AGREEMENT AND PLAN OF MERGER

     AGREEMENT AND PLAN OF MERGER, dated as of December 11, 2004 (this “Agreement”), by and among IVANHOE ENERGY INC., a Yukon corporation (“Parent”), IVANHOE MERGER SUB, INC., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub”), and ENSYN GROUP, INC., a Delaware corporation (the “Company”). Capitalized terms used in this Agreement and not otherwise defined have the respective meanings given them in Section 10.1.

RECITALS

     A. The respective boards of directors of Parent and Merger Sub have approved this Agreement and deemed this Agreement and the transactions contemplated hereby (including the merger of Merger Sub with and into the Company (the “Merger”)) advisable and fair to and in the best interests of their respective shareholders and, by resolutions duly adopted, have approved and adopted this Agreement.

     B. The board of directors of the Company has approved this Agreement and deemed this Agreement and the transactions contemplated hereby (including the Merger) advisable and fair to and in the best interests of the Company and the holders of shares of Company Common Stock and, subject to the terms and conditions contained herein, resolved to recommend the approval by the Company’s shareholders of this Agreement, including the Merger and the transactions contemplated by this Agreement.

     C. Subject to certain exceptions, under the Merger, each issued and outstanding share of common stock, par value $.001 per share, of the Company (the “Company Common Stock”) will be converted into the right to receive the Merger Consideration.

     D. Immediately prior to the Merger, or at such earlier time as the Company may elect, the Company shall, pursuant to the Distribution Agreement, distribute to the Company’s stockholders, indirectly, all of the common stock of Ensyn Renewables Inc. (the “Spin-Off Subsidiary”) by means of the distribution of all of the shares of ERI Holdings, Inc., a new entity to be formed (“ERI Holdings”), that immediately prior to such distribution will own all of the common stock of the Spin-Off Subsidiary (such transaction being referred to as the “Spin-Off Transaction”).

     E. Immediately prior to the Merger but subsequent to the Spin-Off Transaction, Parent and the Canadian holders of the Company Common Stock identified on Schedule 1 hereto who so elect shall consummate their purchase and sale arrangements (the “Canadian Transaction”) contemplated by the Exchange Agreement among Parent and each such Canadian holder of Company Common Stock, the form of which is attached hereto as Exhibit A (the “Canadian Exchange Agreement”), pursuant to which such holders will exchange each of their shares of Company Common Stock for the consideration they would have received in respect of such shares of Company Common Stock pursuant to the Merger had such holders not sold their shares to Parent

immediately prior to the Merger; provided, however, that the Canadian Transaction shall become null and void in the event that the Merger does not occur promptly thereafter.

     F. For U.S. federal income tax purposes, it is intended that the Canadian Transaction and the Merger shall together qualify as a reorganization under the provisions of Section 368(a) of the Code.

     G. Concurrently with the execution of this Agreement, certain holders of shares of Company Common Stock are entering into agreements with Parent, the form of which is attached hereto as Exhibit B, pursuant to which they have agreed not to hedge any shares of Parent Common Stock.

     H. Concurrently with the execution of this Agreement, a significant stockholder of Parent is entering into a voting agreement with Parent and the Company, the form of which is attached hereto as Exhibit C, pursuant to which such stockholder has agreed that, if a Parent Stockholders Meeting is held, such stockholder will vote his shares of Parent Common Stock in favor of the issuance of additional shares of Parent Common Stock, but only if the aggregate Merger Consideration does not consist of more than 42,300,000 shares (as the same may be adjusted for stock splits and the like) of Parent Common Stock (the “Voting Agreement”).

The Indemnity Escrow Fund shall be governed by the terms of an Indemnity Escrow Agreement substantially in the form attached as Exhibit E, with such changes as shall be mutually agreed to by the

6

Each Indemnity Fund Securityholder’s proportionate interest in the Indemnity Escrowed Shares deposited into the Indemnity Escrow Fund shall be based upon such Indemnity Fund Securityholder’s Pro Rata Portion (determined based solely with respect to the Indemnity Fund Securityholders). As more fully provided in the Canadian Exchange Agreement, a portion of the Company Common Stock issuable to the participants in the Canadian Transaction in exchange for their shares of Company Common Stock shall be deposited in the Indemnity Escrow Fund and shall constitute Indemnity Escrowed Shares. The Indemnity Escrowed Shares shall be registered in the name of the Indemnity Escrow Agent for so long as they constitute part of the Indemnity Escrow Fund and, upon distribution to any Indemnity Fund Securityholder, shall be registered in the name of such Indemnity Fund Securityholder. The Indemnity Escrow Fund shall be distributed at the times and in the manner as shall be specified in the Indemnity Escrow Agreement.

     (b) Warrant Escrow. At the Closing, without the act of any Securityholder or any holder of Company Warrants, the Escrowed Warrant Consideration shall be deposited by Parent with Mellon Investor Services, or such other bank or trust company designated by Parent and reasonably approved by the Company (the “Warrant Escrow Agent”).

As more fully provided in the Canadian Exchange Agreement, participants in the Canadian Transaction shall be entitled to receive, in exchange for their shares of Company Common Stock, consideration that includes Participation Rights, determined on the same basis as if they had received the Merger Consideration pursuant to the Merger in respect of each share of Company Common Stock owned by them.

7

     (c) Participation Rights. Holders of the Participation Rights shall be entitled to receive, from time to time, their Pro Rata Portion of the residual assets held in the Warrant Escrow Fund, as the same may be reduced from time to time (i) with respect to the Indemnity Escrowed Warrant Shares only, as a result of distributions to the Parent Indemnified Parties for Damages claims made pursuant to Article VIII and (ii) upon the exercise of Company Warrants, at the times and in the manner as shall be specified in the Warrant Escrow Agreement. The Securityholders acknowledge that, other than in the case of a Change of Control, no distributions from the Warrant Escrow Fund shall be made to Securityholders pursuant to their Participation Rights with respect to Merger Consideration relating to any of the Company Warrants evidenced by Company Warrant Nos. 1 through 20 unless the holder of such Company Warrant has acknowledged in writing to Parent that its Company Warrant has terminated or otherwise expired. All distributions from the Warrant Escrow Fund in respect of the Participation Rights will be made in the same form as the assets then held in the Warrant Escrow Fund. The Participation Rights shall inure to the benefit of the holders of record, as applicable, of (i) Company Common Stock as of the Closing Date (before giving effect to the closing of the Canadian Transaction) and (ii) Company Warrants (to the extent the exercise date of such Company Warrants occurs after the Closing Date), and shall not be transferable (either directly or indirectly) except by operation of law, upon the bankruptcy of such record holder, by will, trust or other testamentary transfer or by gift or sale to a descendent of a record holder, a spouse of a record holder or a descendent of a spouse of a record holder as of the exercise date of such Company Warrants.

     (d) Exchange Agent. At the Closing, Parent shall deposit with Mellon Investor Services, or such other bank or trust company designated by Parent and reasonably approved by the Company (the “Exchange Agent”), (A) certificates representing the aggregate number of shares of Parent Common Stock issuable under Section 2.1(c)(i) (B) minus (x) the Indemnity Escrowed Shares and (y) shares included in the Escrowed Warrant Consideration, (B) sufficient funds necessary to pay the cash component of the Merger Consideration and (C) sufficient funds necessary to pay the cash in lieu of fractional shares of Parent Common Stock to which holders of Company Certificates may be entitled under Section 2.3(d). Such deposited shares of Parent Common Stock and deposited cash, together with any dividends or other distributions paid with respect to those shares, are collectively referred to as the “Exchange Fund.”

     (e) Securityholders’ Representative Fund. At the Closing, Parent shall deposit with Mellon Investor Services, or such other bank or trust company designated by Parent and reasonably approved by the Company (the “Securityholders’ Escrow Agent”), an amount in cash equal to US$1,000,000 (the “Securityholders’ Representative Fund”). The dispensation of the Securityholders’ Representative Fund shall be governed by the terms of a Securityholders’ Representative Fund Escrow Agreement substantially in the form attached as Exhibit G (the “Securityholders’ Representative Fund Escrow Agreement”). As more fully provided in the Securityholders’ Representative Fund Escrow Agreement, the Securityholders’ Representative may draw funds from the Securityholders’ Representative Fund for the payment of its out-of-pocket fees and expenses, including reasonable legal and

accounting fees and expenses (the “Securityholders’ Representative Expenses”) associated with the Securityholders’ Representative’s execution of the duties and obligations as such representative under the terms of this Agreement, the Canadian Exchange Agreement, the Escrow Agreements, the Securityholders’ Representative Fund Escrow Agreement and any letters of transmittal contemplated by this Agreement (the “Securityholders’ Representative Obligations”).

     Section 2.3 Exchange of Certificates.

     (a) Exchange Procedures.

     (i) Letter of Transmittal. Parent shall instruct the Exchange Agent to mail or otherwise deliver to each holder of record of a Company Certificate promptly following the Closing (A) a letter of transmittal (which shall (x) specify that delivery shall be effected, and risk of loss and title to the Company Certificates shall pass, only upon proper delivery of Company Certificates to the Exchange Agent, (y) expressly appoint the Securityholders’ Representative in the capacity set forth in Section 8.7(a), the Escrow Agreements, the Securityholders’ Representative Fund Escrow Agreement and pursuant to the terms of representation set forth in the letter of transmittal, the execution and delivery of which by any holder of Company Common Stock shall constitute such holder’s approval of such terms of representation, and (z) be in such form and to have such other provisions as Parent and the Company may reasonably agree) and (B) instructions for surrendering Company Certificates and receiving the Merger Consideration which such holder shall be entitled pursuant to Section 2.1.

     (ii) Surrender of Company Certificates. Immediately following the Closing, upon surrender of a Company Certificate for cancellation to the Exchange Agent, together with a duly executed letter of transmittal and any other documents reasonably required by the Exchange Agent, the holder of that Company Certificate shall be entitled to receive, as soon as reasonably practicable thereafter, in exchange therefor (A) (x) the Closing Date Portion consisting of Parent Common Stock issuable in exchange for such holder’s Company Certificates (after taking into account all shares then held by such holder) and (y) a check in the amount equal to (I) the cash component of the Merger Consideration plus (II) the cash in lieu of fractional shares of Parent Common Stock payable in respect of such holder’s Closing Date Portion (collectively, the “Closing Date Consideration Payments”) and (B) at the times and in accordance with the terms of the Escrow Agreements, any remaining portion of the Merger Consideration payable to such holder, in each case, less any required withholding of taxes. Any Company Certificates so surrendered shall be cancelled immediately. No interest shall accrue or be paid on any amount payable upon due surrender of Company Certificates. To the extent a holder of Company Common Stock surrenders a Company Certificate together with a duly executed letter of transmittal and any other documents reasonably required by the Exchange Agent prior to or at the Closing, Parent shall use its reasonable commercial efforts to deliver, on the Closing Date or as soon thereafter as

9

practicable, the Closing Date Consideration Payments pursuant to such holder’s instructions set forth in the letter of transmittal.

     (iii) Unregistered Transferees. If any share of Parent Common Stock is to be issued in a name other than that in which the surrendered Company Certificate is registered, then the share of Parent Common Stock may be issued or paid to such a transferee so long as (A) the surrendered Company Certificate is accompanied by all documents required to evidence and effect that transfer and (B) the Person requesting such exchange (1) pays any required transfer taxes or (2) establishes to the reasonable satisfaction of Parent and the Exchange Agent that those taxes have already been paid or are not required.

     (iv) No Other Rights. Until surrendered in accordance with this Section 2.3(a), each Company Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive the Merger Consideration. The Merger Consideration issued or paid upon the surrender of any Company Certificate, or issued or paid subsequently thereto upon the terms of the Escrow Agreements, shall be deemed to have been issued or paid in full satisfaction of all rights pertaining to that Company Certificate and the shares of Company Common Stock formerly represented by it. Nothing in this Section 2.3(a)(iv) shall negate the right of any holder of Company Common Stock, entitled to receive common stock of ERI Holdings in the Spin-Off Transaction prior to the Effective Time, from receiving such common stock.

     (b) Distributions With Respect to Unexchanged Shares. No dividends or other distributions payable with respect to shares of Parent Common Stock that have a record date on or after the Closing Date shall be paid to a holder of an unsurrendered Company Certificate until that Company Certificate is properly surrendered in accordance with this Article II. Subject to applicable Laws, following the proper surrender of any such Company Certificate, there shall be issued or paid to the holder of the certificate representing the Closing Date Shares issued in exchange therefor, without interest, (i) at the time of such surrender, the dividends or other distributions payable with respect to the shares of Parent Common Stock represented by that certificate that have a record date on or after the Closing Date and a payment date on or prior to the date of issuance of that certificate and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to the shares of Parent Common Stock represented by that Parent Certificate that have a record date on or after the Closing Date and a payment date after the date of issuance of that certificate. Any non-cash dividends or other non-cash distributions referred to in the foregoing sentence (i) payable with respect to Indemnity Escrowed Shares shall be deposited into the Indemnity Escrow Fund and (ii) payable with respect to Indemnity Escrowed Warrant Shares shall be deposited into the Warrant Escrow Fund.

     (c) No Further Transfers. At the Closing, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of the shares of Company Common Stock that were outstanding immediately prior to the Closing.

10

     (d) Fractional Shares. No certificates or scrip representing Merger Consideration consisting of fractional shares of Parent Common Stock shall be issued or issuable upon the surrender of Company Certificates, and such fractional share interests will not entitle their owners to vote, to receive dividends or other distributions or to any other rights of a stockholder of Parent. Each holder of Company Certificates who would otherwise have been entitled to receive a fraction of a share of Parent Common Stock under this Article II constituting a Closing Date Share (after taking into account all Company Certificates delivered by such holder) shall receive a cash payment in lieu of such fractional share interest equal to the product obtained by multiplying (A) the fraction of a share of Parent Common Stock constituting a Closing Date Share to which such holder would otherwise have been entitled by (B) the Closing Price. At the Closing, Parent shall deposit an amount in cash with the Exchange Agent sufficient to pay the amounts payable under this Section 2.3(d).

     (e) Termination of Exchange Fund. Any portion of the Exchange Fund that remains unclaimed by the holders of Company Certificates 180 days after the Closing shall be delivered by the Exchange Agent to Parent upon demand. Any holder of Company Certificates who has not complied with this Article II shall thereafter look only to Parent for payment of the Merger Consideration.

     (f) No Liability. None of Parent, Merger Sub, the Surviving Corporation or the Exchange Agent shall be liable to any holder of Company Certificates for any Merger Consideration properly delivered to a public official under applicable abandoned property, escheat or similar Laws. If any Company Certificates have not been surrendered prior to five years after the Closing (or immediately prior to such earlier date on which any Merger Consideration in respect of those Company Certificates would otherwise escheat to or become the property of any Governmental Entity), any Merger Consideration payable in respect of those Company Certificates shall, to the extent permitted by applicable Law, become the property of Parent, free and clear of all claims or interests of any Person previously entitled to that Merger Consideration.

     (g) Lost, Stolen or Destroyed Certificates. If any Company Certificate is lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Company Certificate to be lost, stolen or destroyed and the posting by such Person of a bond in the form reasonably required by Parent as indemnity against any claim that may be made against Parent on account of the alleged loss, theft or destruction, the Exchange Agent shall issue the Merger Consideration in accordance with Section 2.2 in exchange for such lost, stolen or destroyed Company Certificate.

     Section 2.4 Withholding Rights. Each of the Exchange Agent, Parent and the Surviving Corporation shall be entitled to deduct and withhold from the Merger Consideration payable to any Person such amounts as it is required to deduct and withhold from such payment under any applicable Laws. If the Exchange Agent, Parent or the Surviving Corporation, as the case may be, deducts or withholds any such amounts (which amounts shall be paid over to the appropriate Tax authority), such amounts shall be treated for all purposes as having been paid to the Person in respect of whom the

11

Exchange Agent, Parent or the Surviving Corporation, as the case may be, made such deduction and withholding.

     Section 2.5 Treatment of Stock Options. At least 30 days prior to the Closing, the Company shall take such actions as may be necessary, including, without limitation, amending any existing stock plan and notifying all affected individuals, to cause each option to acquire shares of Company Common Stock that may be outstanding as of the Closing (“Company Options”), issued under those option plans set forth in Section 4.11(a) of the Company Disclosure Letter (collectively, the “Company Option Plans”), and each EPIL Option that may be outstanding as of the Closing, issued under those option plans set forth in Section 4.11(a) of the Company Disclosure Letter (collectively, the “EPIL Option Plans”), to be immediately vested and exercisable. At the Effective Time, each Company Option and EPIL Option which is then outstanding shall be canceled.

     Section 2.6 Treatment of Warrants. The Company shall use its reasonable commercial efforts to cause each warrant exercisable for shares of Company Common Stock outstanding immediately prior to the Closing (“Company Warrants”) to be exercised or terminated prior to the Closing. The Company acknowledges that Parent intends to take the position that the Merger, pursuant to which holders of Company Warrants, upon the exercise thereof, shall be entitled to receive shares of common stock of a publicly traded company, is an event that is substantially equivalent to an initial public offering of the Company’s common stock for purposes of determining the expiration date of Company Warrants Nos. 1-20 and, accordingly, the “Warrant Expiration Date,” as defined in each of Company Warrants Nos. 1-20, will be deemed to be the later of the date specified in such Company Warrant and the first anniversary of the Closing Date. The Company shall comply with the notice requirements set forth in the instruments evidencing the Company Warrants, and shall include in the notices to be delivered to the holders of Company Warrants Nos. 1-20 a statement of Parent’s position to the effect set forth in the foregoing sentence. As provided in Section 2.2(b), the portion of the aggregate Merger Consideration that would have been payable in respect of the Company Warrants (had the Company Warrants that remain outstanding and unexercised at the Closing been exercised immediately prior to the Closing) that constitutes Escrowed Warrant Consideration shall be deposited with the Warrant Escrow Agent, of which 33.33% (or 16.665%, as applicable) of the shares of Parent Common Stock constituting part of the aggregate Merger Consideration payable in respect of such Company Warrants shall constitute Indemnity Escrowed Warrant Shares. Upon termination of the Indemnity Escrow Fund, the Indemnity Escrowed Warrant Shares, together with any dividends or distributions paid with respect to the Indemnity Escrowed Warrant Shares, shall become available for distribution pursuant to the terms of the Warrant Escrow Agreement.

     Section 2.7 Dissenting Shares.

Notwithstanding the foregoing, if as a result of the determination of the Closing Price the Additional Shares Issuance Condition will occur, but not more than 42,300,000 shares of Parent Common Stock (as the same may be adjusted as a result of a stock split, combination or other similar change with respect to the Parent Common Stock) will be issued upon consummation of the transactions contemplated by this Agreement (including the Canadian Transaction), Parent may not elect to terminate this Agreement pursuant to Section 9.3(e).

          (h) authorize or commit to do any of the foregoing.

     Section 6.3 Other Actions. Parent and the Company shall not, and shall not permit any of their respective Subsidiaries to, take any action that could reasonably be expected to result in any of the conditions to the Merger set forth in Article VII of this Agreement not being satisfied or satisfaction of those conditions being delayed, except, in the case of the Company, to the extent (a) specifically permitted by Section 6.5(d), its board of directors withdraws, modifies or amends the Company Board Recommendation in accordance with Section 6.5(e) and terminates this Agreement in accordance with Section 9.4(a).

The Company shall provide Parent promptly with the material terms of such Takeover Proposal (including the identity of the Person making such Takeover Proposal, and, if available, a copy of such Takeover Proposal). The Company shall keep Parent reasonably informed on a current basis of the status and details of any such Takeover Proposal.

          (d) Subject to the Company’s compliance with the provisions of this Section 6.5 and prior to obtaining the Requisite Company Vote, nothing in this Agreement shall prevent the Company or its board of directors from:

               (i) engaging in discussions or negotiations with, or furnishing or disclosing any non-public information relating to the Company or any of its Subsidiaries or any Company Assets to, any Person who has made a bona fide, written and unsolicited Takeover Proposal that did not result from a breach of Section 6.5(a) which the board of directors of the Company has determined, in good faith and by a majority of the entire board, after consultation with its financial advisor, is reasonably likely to result in a Superior Proposal, but only so long as (A) the board of directors has determined, after consultation with outside legal counsel, that the failure to take such action is reasonably likely to result in a breach of its fiduciary obligations to the stockholders of the Company under applicable Laws, (B) the Company has caused such Person to enter into a confidentiality agreement with the Company on terms and

               (ii) following the actions permitted under Section 6.5(d)(i), entering into a definitive agreement providing for the implementation of a Superior Proposal, but only so long as (A) the board of directors, acting reasonably, in good faith and by a majority of the entire board, approves such definitive agreement, (B) the board of directors has determined, after consultation with an independent financial advisor that such bona fide, written and unsolicited Takeover Proposal constitutes a Superior Proposal, (C) such definitive agreement is conditioned upon the termination of this Agreement in accordance with its terms and (D) the Company notifies Parent in writing of its intention to terminate this Agreement pursuant to, and after complying with all of the provisions of, Section 9.4(a).

               (i) withdraw, modify or amend, or propose to withdraw, modify or amend, the Company Board Recommendation in any manner adverse to Parent unless the board of directors has (A) acted reasonably, in good faith and by a majority of the entire board and (B) determined, after consultation with outside legal counsel, that failure to take such action would result in a breach of its fiduciary obligations to the stockholders of the Company under applicable Laws; or

          (b) Parent shall notify the Company as promptly as practicable of (i) any notice or other communication from any Person alleging that the consent of such Person (or other Person) is or may be required in connection with the transactions contemplated hereby, (ii) any notice or other communication from any Governmental Entity in connection with the transactions contemplated by this Agreement, (iii) any Legal Action threatened in writing or commenced against or otherwise affecting Parent and its Subsidiaries, but only to the extent such Legal Action would have been required to be disclosed pursuant to Section 5.14 had such Legal Action been pending or, to the Knowledge of Parent, threatened as of the date of this Agreement and (iv) any event, change, occurrence, circumstance or development between the date of this Agreement and the Closing which makes any of the representations or warranties of Parent contained in this Agreement untrue or inaccurate or causes or is reasonably likely to cause any of the conditions set forth in Article VII not to be satisfied.

     Section 6.7 Post-Closing Benefit Plan Matters. If any employee of the Company or any of its Subsidiaries at any time after the Effective Time becomes a participant in (or eligible to participate in) an employee benefit plan, program, policy or arrangement maintained by or contributed to by Parent or any of its Subsidiaries, Parent shall cause such plan, program, policy or arrangement to treat the prior service of such employee with the Company or its Subsidiaries, to the extent prior service is generally recognized under the applicable plan, program, policy or arrangement, as service rendered to Parent or such Subsidiary. Parent shall use its reasonable commercial efforts to cause to be waived any pre-existing condition limitation under its welfare plans that might otherwise apply to such employee (or his or her eligible dependents).

     Section 6.8 Directors’ and Officers’ Indemnification and Insurance.

          (a) For a period of not less than six years after the Closing, Parent shall, and shall cause the Surviving Corporation to, indemnify, defend and hold harmless the current and former directors and officers of the Company and its Subsidiaries (the “D&O Indemnified Parties”) against all Damages incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of acts or omissions at or before the Closing (including the acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby) to the same extent as the D&O Indemnified Parties are indemnified or have the right to advancement of expenses pursuant to the Company Organizational Documents and indemnification agreements, if any, in effect on the date of this Agreement between the D&O Indemnified Parties and the Company or one of its Subsidiaries.

57

          (b) Parent shall cause the Surviving Corporation to maintain in effect for at least six years after the Closing the current policies of directors’ and officers’ liability insurance (the “D&O Insurance”) maintained by the Company or its Subsidiaries or policies of at least the same coverage and amounts containing terms and conditions which are no less advantageous with respect to claims arising out of or relating to events which occurred before or at the Closing so long as Parent or the Surviving Corporation is not required to pay an annual premium in excess of 300% of the last annual premium paid by the Company or its Subsidiaries for such insurance prior to the date of this Agreement (such 300% amount being the “Maximum Premium”). If Parent or the Surviving Corporation is unable to obtain the insurance required under the prior sentence it shall obtain as much comparable insurance as possible for an annual premium equal to the Maximum Premium. The Company represents that the current annual premium is $28,350. Prior to the Closing, Parent shall have the right to cause coverage to be extended under the Company’s D&O Insurance at the Closing by obtaining a six-year “tail” policy on terms and conditions no less advantageous than the Company’s existing D&O Insurance, and such “tail” policy shall satisfy the provisions of this Section 6.8(b).

          (c) If Parent or any of its successors or assigns shall consolidate with or merge into any other entity and is not the continuing or surviving entity of such consolidation or merger or shall transfer all or substantially all of its assets to any other entity, then, and in each case, Parent shall cause proper provisions to be made so that the successors and assigns of Parent will assume the obligations set forth in this Section 6.8.

          (d) The provisions of this Section 6.8 are intended to be for the benefit of, and shall be enforceable by, each D&O Indemnified Party and his or her heirs and legal representatives, it being expressly agreed that the D&O Indemnified Parties to whom this Section 6.8 applies shall be third party beneficiaries of this Section 6.8.

     Section 6.9 Reasonable Commercial Efforts. Upon the terms and subject to the conditions set forth in this Agreement and in accordance with applicable Laws, each of the parties to this Agreement shall use its reasonable commercial efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, as promptly as practicable, all things necessary, proper or advisable under applicable Laws to ensure that the conditions set forth in Article VII are satisfied and to consummate the transactions contemplated by this Agreement. If, at any time after the Closing, any further action is necessary or desirable to carry out the purposes of this Agreement, including the execution of additional instruments, the proper officers and directors of each party to this Agreement shall take all such necessary action.

     Section 6.10 Consents; Filings; Further Action.

          (a) Upon the terms and subject to the conditions of this Agreement and in accordance with applicable Laws, each of the parties to this Agreement shall use its reasonable commercial efforts to (i) obtain any consents, approvals or other authorizations required to be obtained by Parent or the Company or any of their

58

respective Subsidiaries in connection with the Merger and the other transactions contemplated by this Agreement, and (ii) make the necessary filings and notifications, and thereafter make any other submissions either required or deemed appropriate by both parties, acting reasonably, with respect to the Merger and the other transactions contemplated by this Agreement required under (A) the Securities Act, the Exchange Act and state securities or “blue sky” Laws, (B) the HSR Act, (C) the DGCL, (D) any Canadian or other applicable Laws and (E) the rules and regulations of the Toronto Stock Exchange and the NASDAQ Small-Cap Market. Parent, on the one hand, and the Company, on the other hand, shall cooperate and consult with each other in connection with the making of all such filings and notifications, including by providing copies of all such documents to the non-filing party and its advisors prior to filing, and neither party will file any such document if the other party shall have reasonably objected to the filing of such document. Parent, on the one hand, and the Company, on the other hand, shall not consent to any voluntary extension of any statutory deadline or waiting period or to any voluntary delay of the consummation of the Merger and the other transactions contemplated by this Agreement at the behest of any Governmental Entity without the consent of the other party, which consent shall not be unreasonably withheld or delayed.

          (b) If Parent, on the one hand, or the Company, on the other hand, or any of their respective Affiliates receives a request for additional information or documentary material from any Governmental Entity with respect to the transactions contemplated by this Agreement, then such party will endeavor in good faith to make, or cause to be made, as soon as reasonably practicable and after consultation with the other party, an appropriate response in compliance with such request. Parent will advise the Company promptly in respect of any understandings, undertakings or agreements (oral or written) which Parent proposes to make or enter into with the Federal Trade Commission, the Department of Justice or any other Governmental Entity in connection with the transactions contemplated by this Agreement. In furtherance and not in limitation of the foregoing, Parent shall use its reasonable best efforts to resolve such objections, if any, as may be asserted with respect to the transactions contemplated by this Agreement under any antitrust, competition or trade regulatory laws, rules or regulations of any Governmental Entity.

          (c) Notwithstanding the foregoing, nothing in this Section 6.10 shall require, or be construed to require, Parent or the Company, in connection with the receipt of any regulatory approval, to propose or agree to (i) sell or hold separate and agree to sell, divest or to discontinue or limit, before or after the Closing, any asset, business or interest in any asset or business of Parent, the Company or any of their respective Affiliates (or consent to any such act) or (ii) any condition relating to, change in or restriction on, the operations of any such asset or business if such condition, change or restriction could reasonably be expected to adversely impact the economic or business benefits to such party of the transactions contemplated by this Agreement.

     Section 6.11 Plan of Reorganization. This Agreement is intended to constitute a “plan of reorganization” within the meaning of Section 1.368-2(g) of the income tax regulations promulgated under the Code. From and after the date of this

59

Agreement and until the Closing, each of Parent and the Company shall use its reasonable commercial efforts (and shall cause their respective Subsidiaries to use their reasonable commercial efforts) to cause the Merger to qualify, and shall not, without the prior written consent of the other party, knowingly take any actions or cause any actions to be taken which would or would reasonably be likely to prevent the Merger from qualifying, as a reorganization under the provisions of Section 368(a) of the Code. Following the Closing, and consistent with any such consent, neither Parent nor any of its Subsidiaries, nor any of its Affiliates, shall knowingly take any action or cause any action to be taken which would cause the Merger to fail to so qualify as a reorganization under Section 368(a) of the Code.

     Section 6.12 Public Announcements. Parent and the Company shall consult with each other before issuing any press release or otherwise making any public statements with respect to this Agreement or any of the transactions contemplated by this Agreement and shall not issue any such press release or make any such public statement prior to such consultation, except to the extent required by applicable Law or the requirements of the Toronto Stock Exchange or the NASDAQ Small-Cap Market, in which case the issuing party shall use reasonable commercial efforts to consult with the other party before issuing any such release or making any such public statement; provided, however, that, unless required by Applicable Law or the rules and regulations of the Toronto Stock Exchange or the NASDAQ Small-Cap Market, prior to Closing in no event shall Parent or its Subsidiaries release any information as to the satisfaction of the condition set forth in Section 7.2(n).

     Section 6.13 Stock Exchange Matters; Parent Stockholders Meeting.

          (a) Parent shall (i) use its reasonable commercial efforts to obtain an exemption from Rule 4350(i)(C)(ii) of the Nasdaq Marketplace Rules to the effect that no approval by Parent’s stockholders will be required in connection with the transactions contemplated by this Agreement (the “Nasdaq Exemption”) and (ii) file the requisite notice with the Toronto Stock Exchange and the appropriate forms with the NASDAQ Small-Cap Market for the listing of the shares of Parent Common Stock issuable pursuant to the Merger, the Canadian Transaction and upon exercise of all outstanding Company Warrants as soon as practicable after the date of this Agreement. Parent will use reasonable commercial efforts to obtain from the Toronto Stock Exchange acceptance of the requisite notice for the listing of additional shares with respect to the shares of Parent Common Stock issuable pursuant to the Merger, the Canadian Transaction and upon exercise of all outstanding Company Warrants.

          (b) Whether or not the Requisite Vote is required, Parent shall prepare, with the cooperation of the Company, an information circular (the “Parent Proxy Statement”) relating to a special meeting of the stockholders of Parent to be held to consider the issuance of Parent Common Stock in connection with this Agreement (including the Canadian Transaction) (the “Parent Stockholders Meeting”).

(“EPIL”) (or the shares of EPIL common stock issued upon exercise thereof) to be cancelled or otherwise converted or exchanged prior to the Closing Date either for (i) Company Options (which shall then be treated in accordance with Section 2.5) or (ii) shares of Company Common Stock (which shall be treated in accordance with Section 2.1(c)). To the extent any EPIL Options remain outstanding following the Closing Date or any holders of EPIL Options shall have exercised their EPIL Options prior to the Closing Date and as a result shares of EPIL common stock are outstanding following the Closing Date that are not owned by the Surviving Corporation or by Parent, Parent shall be entitled to make a claim against the Indemnity Escrow Fund as provided in Section 8.2(a)(ix).

64

Parent, the cost of acquiring the Ensyn Energy Minority Interest held by ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇-▇▇▇▇▇▇▇ shall not exceed the cost of acquiring the Ensyn Energy Minority Interest owned by ▇▇▇▇▇▇ ▇▇▇▇▇.

     Section 6.28 Negotiations Regarding Tax Condition Covenant. If the conditions to the Closing contained in Article VII have been satisfied or waived (other than any conditions that by their nature are to be satisfied at the Closing) and the Closing nevertheless is not being effected solely due to the failure to be satisfied or waived of the condition set forth in Section 7.3(f) of this Agreement, then the Company and Parent shall negotiate in good faith with each other regarding an amendment to this Agreement revising or restructuring the transactions contemplated by this Agreement, on substantially the same economic terms to both parties, in a manner that would qualify as a tax-free reorganization under the Code on terms mutually acceptable to the Company and Parent.

     Section 6.29 Tax Election. Company shall make an election to close its tax year end as of the Closing Date and Parent shall take any actions reasonably requested by the Company or the Securityholders’ Representative to cause that to happen.

               (xii) any claim made with respect to the matter listed as Item 1 of Section 4.34 of the Company’s Disclosure Letter.

          (b) By Parent and Surviving Corporation. From and after the Closing, Parent and the Surviving Corporation (in such capacity, each a “Parent Indemnifying Party” and collectively, the “Parent Indemnifying Parties”) shall, jointly and severally, indemnify, save and hold harmless the Securityholders and each of their successors and permitted assigns (each, a “Company Indemnified Party” and collectively, the “Company Indemnified Parties”) from and against any and all Damages, to the extent incurred in connection with, arising out of, resulting from or incident to:

               (i) a breach of any representation or warranty made by Parent or Merger Sub in this Agreement or in the Parent Closing Certificate; provided, however, that the Company shall not be entitled to indemnification for any breach or inaccuracy of any of the representations and warranties set forth in Article V if such breach or inaccuracy was disclosed in the Parent Closing Certificate and related to any matter arising after the date of this Agreement and prior to the Closing Date; or

               (ii) a breach of any covenant or agreement made, or to be performed, by Parent or Merger Sub in this Agreement.

          (c) Limitations.

               (i) Notwithstanding anything to the contrary contained in this Article VIII, the maximum liability of any Securityholder under Section 8.2(a) shall be limited to, and paid solely from, such Securityholder’s Pro Rata Portion of the Indemnity Escrow Fund or Indemnity Warrant Escrowed Shares, as applicable, as the same may be reduced from time to time in accordance with this Agreement and the

73

Escrow Agreements. For the avoidance of doubt, Securityholders that are a party to the Canadian Transaction shall have such additional contractual liability with respect to the Canadian Transaction as shall be provided in the Canadian Exchange Agreement, which liability shall not be secured by the Indemnity Escrow Fund or the Indemnity Warrant Escrowed Shares.

               (ii) The Company Indemnifying Parties shall have no obligation to indemnify the Parent Indemnified Parties for any Damages under Section 8.2(a)(i) unless and until the Company Indemnifying Parties’ aggregate indemnification obligations thereunder with respect to such Damages shall exceed $500,000 (the “Deductible Amount”), whereupon the Parent Indemnified Parties shall be entitled to receive indemnification for the amount of Damages in excess of the Deductible Amount; provided, however, that the foregoing Deductible Amount limitation shall not apply to any claim for indemnification to the extent incurred in connection with, arising out of or resulting from the Company’s breach of the representations or warranties set forth in Section 4.3 [Corporate Authorization], Section 4.7 [Subsidiaries] (second sentence and clause (ii) of first sentence only), Section 4.10 [Capitalization], Section 4.11 [Options], Section 4.24 [Intellectual Property] or Section 4.36 [Brokers and Finders] of this Agreement (or in the Company Closing Certificate to the extent relating to the Company’s representations and warranties in such Sections); provided further, that with respect to any such breach of the representations or warranties set forth in Section 4.24 [Intellectual Property], the Deductible Amount relating to such breach shall be $100,000 instead of $500,000, but the Deductible Amount with respect to all other applicable representations and warranties of the Company shall remain $500,000, irrespective of any claims relating to representations or warranties set forth in Section 4.24 [Intellectual Property].

               (iii) The Parent Indemnifying Parties shall have no obligation to indemnify the Company Indemnified Parties for any Damages under Section 8.2(b)(i) unless and until the Parent Indemnifying Parties’ aggregate indemnification obligations thereunder with respect to Damages shall exceed $500,000, whereupon the Company Indemnified Parties shall be entitled to receive indemnification for the amount of such Damages in excess of $500,000; provided, however, that the foregoing $500,000 limitation shall not apply to any claim for indemnification to the extent incurred in connection with, arising out of or resulting from Parent’s breach of the representations or warranties set forth in Section 5.3[Corporate Authorization] or Section 5.23 [Brokers and Finders] (or in the Parent Closing Certificate to the extent relating to the Parent’s representations and warranties in such Sections).

               (iv) Cap. No indemnification payment by Indemnifying Parties shall be payable to Indemnified Parties to the extent the aggregated claims hereunder for Damages of such Indemnified Parties exceeds (A) in the case of claims against the Parent Indemnifying Parties, an amount equal to $25,000,000, and (B) in the case of claims against the Company Indemnifying Parties, the amount of the Indemnity Escrow Fund plus the Indemnity Escrowed Warrant Shares (such shares, together with any stock dividends and stock distributions that have been paid thereon and deposited

74

into the Warrant Escrow Fund, the “Indemnity Escrowed Warrant Portion”) up to an aggregate value of $25,000,000 in paid-out claims, with the value of any Indemnity Escrowed Shares and Indemnity Escrowed Warrant Shares paid to satisfy a claim to be determined in accordance with Section 8.3(b); provided, that if only 16.665% of the Indemnity Escrowed Shares and the Indemnity Escrowed Warrant Shares have been deposited into the Indemnity Escrow Fund and the Warrant Escrow Fund, respectively, as contemplated by this Agreement (under the definitions of “Indemnity Escrowed Shares” and “Indemnity Escrowed Warrant Shares”), the reference to “$25,000,000” in the foregoing clauses (A) and (B) shall be replaced with “$12,500,000.”

          (d) Interpretation. The term “Damages” as used in this Article VIII is not limited to matters asserted by third parties against an Indemnified Party, but includes Damages incurred or sustained by the Indemnified Party in the absence of third party claims. The term “Damages” as used in this Article VIII shall not include any consequential damages or punitive damages or awards (unless payable as a result of a Third Party Claim).

          (e) Damage Payments. Except as provided in Section 6.8 with respect to a Company Indemnifying Party’s right to indemnification for acts or omissions of an officer or director of the Company or its Subsidiaries, each of the Company Indemnifying Parties and the Securityholders’ Representative hereby agrees that if, following the Closing, any payment is made pursuant to this Article VIII by such Company Indemnifying Party in respect of any Damages (a “Damage Payment”), such Company Indemnifying Party shall have no rights against the Surviving Corporation, or any current or former director, officer or employee thereof (in their capacity as such), whether by reason of contribution, indemnification, subrogation or otherwise, in respect of any such Damage Payment, and shall not take any action against the Surviving Corporation or any such Person with respect thereto. Any rights with respect to Damage Payments which any of the Company Indemnifying Parties or the Securityholders’ Representative may, by operation of law or otherwise, have against the Surviving Corporation or any such Person shall, effective at the time of the Closing, be deemed to be hereby expressly and knowingly waived.

          (f) Adjustment to Purchase Price for Tax Purposes. It is the intention of the parties to treat any indemnity payment made under this Agreement as an adjustment to the purchase price for all federal, state, local and foreign Tax purposes, and the parties agree to file their Tax Returns accordingly.

     Section 8.3 Certain Matters Relating to the Indemnity Escrow.

          (a) Escrow Period. The period during which claims for indemnification from the Indemnity Escrow Fund and the Warrant Escrow Fund may be initiated (the “Escrow Period”) shall commence on the Closing Date and terminate on the Indemnity Escrow Termination Date. Upon expiration of (i) the Escrow Period, the Indemnity Escrow Fund shall terminate with respect to all Indemnity Escrowed Shares and other property in the Indemnity Escrow Fund at such time (including any shares of Parent Common Stock or other Parent equity securities (“New Shares”) issued or

75

distributed by Parent (upon a stock split or otherwise) in respect of the Indemnity Escrowed Shares and constituting part of the Indemnity Escrow Fund) and (ii) the Indemnity Escrowed Warrant Portion of the Warrant Escrow Fund shall no longer be available for the satisfaction of any claims under this Article VIII; provided, however, that the number of Indemnity Escrowed Shares (and any related New Shares), the part of the Indemnity Escrowed Warrant Portion of the Warrant Escrow Fund, and any other property which, subject to the provisions of this Article VIII, the Indemnity Escrow Agreement (including any objection of the Securityholders’ Representative in accordance with the provisions of the Indemnity Escrow Agreement) and the Warrant Escrow Agreement, as applicable, are necessary (i) to satisfy any unsatisfied claims specified in any Parent Indemnification Certificate delivered to the Indemnity Escrow Agent prior to the expiration of the Escrow Period and (ii) as further provided in Section 7(b) of the Indemnity Escrow Agreement, to pay the estimate of the fees of the Securityholders’ Representative in fulfilling his Securityholders’ Representative Obligations in order to resolve such unsatisfied claims shall remain in the Indemnity Escrow Fund (with respect to the Indemnity Escrowed Shares), which fund shall remain in existence, and shall remain available (with respect to the Indemnity Escrowed Warrant Portion), until all such claims have been resolved. As such claims are resolved, (i) the Indemnity Escrow Agent shall deliver Indemnity Escrowed Shares (and any related New Shares) and other property remaining in the Indemnity Escrow Fund and not necessary to satisfy such resolved claims or any remaining unresolved claims pursuant to the terms of the Indemnity Escrow Agreement and (ii) any part of the Indemnity Escrowed Warrant Portion of the Warrant Escrow Fund that is not necessary to satisfy such resolved claims or any remaining unresolved claims pursuant to the terms of the Indemnity Escrow Agreement shall remain in the Warrant Escrow Fund for distribution to holders of Company Warrants following such holders’ exercise of their Company Warrants.

          (b) Valuation of Indemnity Escrowed Shares. For purposes of making a Damage Payment pursuant to this Article VIII, each Indemnity Escrowed Share held as part of the Indemnity Escrow Fund and each Indemnity Escrowed Warrant Share held as part of the Warrant Escrow Fund, in either case consisting of Parent Common Stock, shall be deemed to be valued at the Closing Price (as the same shall be adjusted as a result of a stock split, stock dividend, stock distribution, combination, reclassification, recapitalization or other similar change with respect to Parent Common Stock occurring after the Closing Date), notwithstanding the then current market price of the Parent Common Stock.

     Section 8.4 Procedure for Claims between Parties.

          (a) If a claim for Damages is to be made by a Parent Indemnified Party entitled to indemnification hereunder, Parent shall be the only party entitled to give notice to the Securityholders’ Representative and shall give such notice to the Securityholders’ Representative and the Indemnity Escrow Agent as soon as reasonably practicable after Parent becomes aware that a fact, condition or event has occurred or exists which may give rise to Damages for which indemnification by a Parent Indemnified Party may be sought under this Article VIII (a “Notice”). If a claim for

76

Damages is to be made by a Company Indemnified Party entitled to indemnification hereunder, the Securityholders’ Representative shall be the only party entitled to give Notice to Parent, and shall give such Notice to Parent as soon as reasonably practicable after the Securityholders’ Representative becomes aware that a fact, condition or event has occurred or exists which may give rise to Damages for which indemnification by a Company Indemnified Party may be sought under this Article VIII. In each case, the Notice shall consist of a certificate signed by an officer of Parent (a “Parent Indemnification Certificate”) or a certificate by the Securityholders’ Representative (a “Securityholders’ Indemnification Certificate”), as applicable, that shall (i) describe in reasonable detail the facts and circumstances known to the Indemnified Party that gave rise to such indemnification claim and the amount arising therefrom and (ii) if the aggregate amount of Damages exceeds the applicable Deductible Amount (after taking into account any other indemnification claims made by the Parent Indemnified Parties or Company Indemnified Parties, as applicable, pursuant to this Article VIII), provide for a demand of payment of the amount. Any delay in submitting a Notice to the Securityholders’ Representative or Parent, as applicable, shall not relieve any Indemnifying Party of any liability hereunder, except to the extent that the Indemnifying Party was prejudiced by such delay; provided that Parent and the Securityholders’ Representative shall only be entitled to submit a Notice during the Escrow Period.

          (b) If the Securityholders’ Representative does not object in writing within the 30 day period after delivery by Parent of the Notice, such failure to so object shall be an irrevocable acknowledgment by the Securityholders’ Representative on behalf of the Company Indemnifying Parties that the Parent Indemnified Parties identified in the Notice are entitled to the full amount of the claim for Damages set forth in such Notice. If Parent does not object in writing within the 30 day period after delivery by the Securityholders’ Representative of the Notice, such failure to so object shall be an irrevocable acknowledgment by Parent that the Company Indemnified Parties identified in the Notice are entitled to the full amount of the claim for Damages set forth in such Notice.

     Section 8.5 Defense of Third Party Claims.

          (a) If any lawsuit or enforcement action is filed against an Indemnified Party by any third party (other than a Contest, with respect to which the provisions of Section 8.8 shall apply) (each a “Third Party Claim”) for which indemnification under this Article VIII may be sought, written notice (“Third Party Notice”) thereof shall be given by Parent to the Securityholders’ Representative or by the Securityholders’ Representative to Parent, as applicable, as promptly as practicable, but in any event within 30 days of service. The Third Party Notice shall describe in reasonable detail the facts and circumstances known to the Indemnified Party that gave rise to such indemnification claim, and the amount or good faith estimate of the amount arising therefrom. The delay of any Indemnified Party in giving a Third Party Notice hereunder shall not affect rights to indemnification hereunder, except to the extent that the Indemnifying Party was prejudiced by such delay.

77

          (b) After receipt of such Third Party Notice, the Indemnifying Party shall be entitled, if it so elects at its own cost, risk and expense, (i) to take control of the defense and investigation of such Third Party Claim, (ii) to employ and engage attorneys of its own choice (provided, that such attorneys are reasonably acceptable to the Indemnified Party) to diligently handle and defend the same, unless the named parties to such action or proceeding include both one or more Indemnifying Parties and an Indemnified Party, and the Indemnified Party has been advised in writing by counsel that there are one or more legal defenses available to such Indemnified Party that are different from or additional to those available to an applicable Indemnifying Party or there is otherwise a conflict of interest that exists or is reasonably likely to exist that would make it inappropriate, in the reasonable judgment of the Indemnified Party, for the same counsel to represent both the Indemnified Party and the Indemnifying Parties, in which event such Indemnified Party shall be entitled, at the Indemnifying Parties’ cost and expense, to separate counsel of its own choosing (provided, that such cost and expense shall be limited to one firm of attorneys, together with appropriate local counsel, for any such Third Party Claim) and (iii) to compromise or settle such claim, which compromise or settlement shall be made only with the written consent of the Indemnified Party, unless the Indemnified Party and its Affiliates are released in full in connection with the settlement, such consent not to be unreasonably withheld or delayed. Notwithstanding the foregoing, the Indemnifying Party shall not be entitled to assume the defense of any Third Party Claim if the Third Party Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the Indemnified Party that the Indemnified Party reasonably determines, after conferring with outside counsel, cannot be separated from any related claim for money damages. If such equitable relief or relief for other than money damages portion of the Third Party Claim can be so separated from that for money damages, the Indemnifying Party shall be entitled to assume the defense of the portion relating to money damages. If the Indemnifying Party elects to assume the defense of a Third Party Claim, the Indemnified Party shall cooperate in all reasonable respects with the Indemnifying Party and its attorneys in the investigation, trial and defense of such Third Party Claim and any appeal arising therefrom; provided, however, that the Indemnified Party may, at its own cost, participate in the investigation, trial and defense of such lawsuit or action and any appeal arising therefrom and may, at its own expense, retain separate counsel of its choosing. The parties shall cooperate with each other in any notifications to insurers.

          (c) If the Indemnifying Party fails to notify the Indemnified Party within 30 days after receipt of the Third Party Notice that the Indemnifying Party elects to defend the Indemnified Party pursuant to this Section 8.5, or if the Indemnifying Party elects to defend the Indemnified Party pursuant to this Section 8.5 but fails to diligently prosecute or settle the Third Party Claim, which failure continues for ten days after notice to the Indemnifying Party from the Indemnified Party of such failure, then the Indemnified Party against which such claim has been asserted will have the right to undertake, and the cost and expense thereof will constitute Damages, the defense, compromise or settlement of such Third Party Claim on behalf of and for the account and risk of the Indemnifying Parties. The Indemnified Party shall have full control of such defense and proceedings; provided, however, that such claim shall not be compromised

78

or settled without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed. If the Indemnified Party assumes the defense of the claim, the Indemnifying Party shall cooperate in all reasonable respects with the Indemnified Party in such defense and make available to the Indemnified Party at the Indemnifying Party’s expense, all such witnesses, records, materials and information in the Indemnifying Party’s possession or under the Indemnifying Party’s control relating thereto as are reasonably required by the Indemnified Party, and the Indemnified Party will keep the Indemnifying Party reasonably informed of the progress of any such defense, compromise or settlement.

          (d) Subject to Section 8.2(c), in the event the Securityholders’ Representative has consented to any settlement pursuant to this Section 8.5, the Securityholders’ Representative shall promptly deliver a notice to the Indemnity Escrow Agent (with a copy to Parent) specifying the monetary amount of such settlement and instructing the Indemnity Escrow Agent to deliver cash and/or Indemnity Escrowed Shares out of the Indemnity Escrow Fund valued at such monetary amount (together with any related New Shares) to the applicable Parent Indemnified Party; provided, that if the Securityholders’ Representative shall fail to deliver such notice to the Indemnity Escrow Agent, Parent shall be authorized to deliver the notice to the Indemnity Escrow Agent (with a copy to the Securityholders’ Representative) instructing the Indemnity Escrow Agent to deliver cash and/or Indemnity Escrowed Shares out of the Indemnity Escrow Fund valued (as provided in Section 8.3(b)) at the monetary amount of such settlement (together with any related New Shares) to the applicable Parent Indemnified Party.

          (e) Notwithstanding anything to the contrary contained in this Section 8.5, (x) if at the time of or subsequent to the receipt of a Third Party Claim the Indemnity Escrow Fund is not sufficient to cover the full amount of the Damages relating to such Third Party Claim that may be payable to the Parent Indemnified Parties under this Article VIII (assuming the full amount of such Damages becomes payable to the Parent Indemnified Parties) (the “Full Damages Amount”) and either (i) the Full Damages Amount exceeds the then remaining value of the Indemnity Escrow Fund (excluding any portion thereof subject to a pending claim) by $3,500,000 or (ii) the remaining value of the Indemnity Escrow Fund (determined valuing Indemnity Escrowed Shares at the Closing Price and excluding any portion thereof already subject to a pending claim) is less than 50% of the Full Damages Amount, (y) if the Third Party Claim relates to Intellectual Property or (z) if no Damages are specified in the Third Party Claim and at the time of or subsequent to the receipt of the Third Party Claim the remaining value of the Indemnity Escrow Fund (determined valuing Indemnity Escrowed Shares at the Closing Price and excluding any portion thereof already subject to a pending claim) is less than $500,000, then the Securityholders’ Representative shall no longer have the right to control or participate in the defense or investigation of such Third Party Claim (which right shall vest with the Parent), or to compromise or settle such Third Party Claim or to consent to any such compromise or settlement; provided, that the last two sentences of Section 8.5(c) shall become applicable with respect to any such Third Party Claim.

79

     Section 8.6 Resolution of Conflicts and Claims.

          (a) If an Indemnifying Party objects in writing to any claim (or part of any claim) for indemnification made by an Indemnified Party (an “Objection Notice”), the Indemnified Party and Indemnifying Party shall attempt in good faith to agree upon the rights of the respective parties with respect to each of such claims. If the Indemnified Party and Indemnifying Party should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties and, if such agreement involves a payment to a Parent Indemnified Party, shall be furnished to the Indemnity Escrow Agent and the Warrant Escrow Agent. The Indemnity Escrow Agent and the Warrant Escrow Agent shall each be entitled to rely on any such memorandum and distribute Indemnity Escrowed Shares, Indemnity Escrowed Warrant Shares and other property from the Indemnity Escrow Fund and Warrant Escrow Fund in accordance with the terms of the Escrow Agreements.

          (b) If no such agreement can be reached after good faith negotiations and prior to 30 days after delivery of an Objection Notice, either Parent or the Securityholders’ Representative may demand arbitration of the matter unless the amount of the Damages that is at issue is the subject of a pending litigation involving a Third Party Claim, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration, and in either such event the matter shall be settled by arbitration conducted by a panel of three arbitrators. Within ten business days of written notice by the party seeking arbitration under this Agreement (such notice, an “Arbitration Request”), the party requesting arbitration shall appoint one person as an arbitrator and, within ten days thereafter, the other party shall appoint the second arbitrator. At the time of appointment, the appointing party shall designate whether its arbitrator will be treated as a neutral and independent arbitrator or as a partisan arbitrator to become effective upon the appointment of the third impartial and neutral arbitrator. Within ten days after the Arbitration Request, the two arbitrators so selected shall select a third arbitrator. Unless the parties agree otherwise, such third impartial and neutral arbitrator shall be a licensed attorney with ten or more years experience negotiating and drafting commercial contracts similar to this Agreement or a senior executive or retired senior executive with ten or more years of experience with companies having business similar to the Retained Business or of the Spin-Off Subsidiary. If the Securityholders’ Representative fails to select an arbitrator during such ten day period, then the parties agree that Parent may select, in its sole discretion, such arbitrator. If Parent fails to select an arbitrator during such ten day period, then the parties agree that the Securityholders’ Representative may select, in its sole discretion, such arbitrator.

          (c) Any such arbitration shall be held in the State of New York under the commercial arbitration rules then in effect of the American Arbitration Association, subject to the discretion of the arbitrators to permit discovery or portions of the arbitration hearing to be conducted in other jurisdictions to minimize the inconvenience or costs to either of the parties. If the American Arbitration Association or its successor ceases to provide arbitration services, then the term “American Arbitration Association” as used in this Agreement will thereafter mean and refer to

80

J.A.M.S./ENDISPUTE. Each of the parties to the arbitration shall bear its own expenses, except that all expenses relating to the fees of the arbitrators and the administrative fee of the American Arbitration Association shall be shared equally between the parties. If the parties are not able to agree upon the rate of compensation of the impartial and neutral arbitrator, the American Arbitration Association shall determine such rate based upon the normal and customary hourly or daily consulting rate of such impartial and neutral arbitrator. The arbitrators shall be instructed to conduct the arbitration in a manner as expeditious as reasonably possible, consistent with the parties’ intention to have a full and fair hearing on the merits of the disputed matter. Unless otherwise agreed by the parties, the parties shall make their initial and any supplemental claims to the arbitration panel within 20 days after the Arbitration Request. The arbitrators shall set a limited time period and establish procedures designed to reduce the cost and time for discovery while allowing the parties an opportunity, adequate in the sole judgment of the majority of the three arbitrators to discover relevant information from the opposing parties about the subject matter of the dispute. The majority of the three arbitrators shall rule upon motions to compel or limit discovery and shall have the authority to impose sanctions, including attorneys’ fees and costs, to the same extent as a competent court of law or equity, should the majority of the three arbitrators determine that discovery was sought without substantial justification or that discovery was refused or objected to without substantial justification. Each party shall supply to the other party copies of any and all materials that are supplied to the arbitrators concurrently with delivery of such materials to the arbitrators. At least five days prior to the commencement of any hearing on the merits before the arbitration panel, each party shall deliver to the arbitrators and to the other party a list of all witnesses whose testimony such party tends to introduce in connection with all such hearings as well as copies of all documents not previously delivered which such party intends to introduce into evidence or to rely upon in connection with such hearings. The decision of a majority of the three arbitrators as to the validity and amount of any claim shall be final, binding, and conclusive upon the parties to this Agreement. Such conclusions shall be set forth in a written award, judgment, decree or order awarded by the arbitrators, and the Escrow Agent shall be entitled to rely on, and make distributions from the Indemnification Escrow Fund in accordance with, the terms of such award, judgment, decree or order as applicable. Within 30 days of a decision of the arbitrators requiring payment by one party to another, such party shall make the payment to such other party or, in the case of a payment to a Parent Indemnified Party, cause the Escrow Agent to make the payment to such Indemnified Party.

          (d) Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction. The foregoing arbitration provision shall apply to any dispute between Indemnifying Parties and Indemnified Parties under this Article VIII hereof, whether relating to claims upon the Indemnity Escrow Fund or to the other indemnification obligations set forth in this Article VIII, and shall be the sole and exclusive remedy for any such dispute. The arbitrators chosen in accordance with these provisions shall not have the power to alter, amend or otherwise affect the terms of the arbitration provisions or other provisions in this Agreement.

81

     Section 8.7 Securityholders’ Representative.

          (a) At the Closing, ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇ shall be constituted and appointed, without any further act of any Securityholder, the Company Indemnifying Parties’ and the Company Indemnified Parties’ representative (the “Securityholders’ Representative”) and, as such, shall serve as and have all powers as agent and attorney-in-fact for and on behalf of each Company Indemnifying Party or Company Indemnified Party, as the case may be: (i) to give and receive notices and communications on their behalf with respect to any matters related to this Agreement, the Escrow Agreements or the Securityholders’ Representative Fund Escrow Agreement; (ii) to enter into and perform under the Escrow Agreements and the Securityholders’ Representative Fund Escrow Agreement; (iii) to authorize delivery of Indemnity Escrowed Shares or other property from the Indemnity Escrow Fund to a Parent Indemnified Party; (vi) to object to such deliveries and any claims set forth in any Parent Indemnification Certificate; (v) to agree to, negotiate, enter into settlements and compromises of, and demand arbitration and comply with orders of courts and awards of arbitrators with respect to any claim for indemnification pursuant to this Article VIII; (vi) to litigate, mediate, arbitrate, defend, enforce or take any other actions and execute the Escrow Agreements and any other documents that the Securityholders’ Representative deems advisable in connection with enforcing any rights or obligations or defending any claim or action under this Agreement on behalf of the Company Indemnifying Parties and the Company Indemnified Parties; (vii) to sign receipts, consents or other documents in connection with the Securityholders’ Representative’s duties hereunder; and (viii) to take any and all actions necessary or appropriate in the judgment of the Securityholders’ Representative for the accomplishment of the foregoing, in each case, without having to seek or obtain the consent of any Securityholder. Notice or communications to or from the Securityholders’ Representative shall constitute notice to or from the Company Indemnifying Parties and the Company Indemnified Parties. All actions to be taken by a Company Indemnified Party or Company Indemnifying Party, as the case may be, shall be taken solely by the Securityholders’ Representative.

          (b) Without limiting the generality of the foregoing Section 8.7(a), the Securityholders’ Representative shall not incur any liability with respect to any action taken or suffered by him in reliance upon any direction, instruction, consent, statement or other document believed by him to be genuinely and duly authorized, nor for any action or inaction in reliance in good faith upon advice of legal counsel. The Securityholders’ Representative shall have rights to indemnification, contribution and reimbursement, as set forth in the Securityholders’ Representative Fund Escrow Agreement, from each Securityholder. If the Securityholders’ Representative shall die, become disabled, resign or otherwise be unable to fulfill his responsibilities hereunder, Securityholders, acting by consent of Securityholders having an interest in the Indemnity Escrow Fund equal to a majority of the Indemnity Escrowed Shares then held in the Indemnity Escrow Fund (a “Majority”) shall, as soon as practicable after such death, resignation or disability, appoint a successor to the Stockholders’ Representative and immediately thereafter notify Parent of the identity of such successor. If a Majority chooses to remove the Securityholders’ Representative for any reason, such Majority

82

shall simultaneously appoint a successor to the Securityholders’ Representative and immediately thereafter notify Parent of the identity of such successor. Any such successor pursuant to either of the preceding two sentences shall succeed the Securityholders’ Representative as Securityholders’ Representative hereunder.

          (c) A decision, act, consent or instruction of the Securityholders’ Representative shall constitute a decision of the Company Indemnifying Parties or the Company Indemnified Parties, as the case may be, and shall be final, binding and conclusive upon the Company Indemnifying Parties or the Company Indemnified Parties, as the case may be. The Indemnity Escrow Agent and any Parent Indemnified Party may rely upon any decision, act, consent or instruction of the Securityholders’ Representative as being the decision, act, consent or instruction of the Company Indemnifying Parties or the Company Indemnified Parties, as the case may be. Although the Securityholders’ Representative shall not be obligated to obtain instructions from the Company Indemnifying Parties or the Company Indemnified Parties, as the case may be, prior to any decision, act, consent or instruction, if, and to the extent that, the Securityholders’ Representative receives any written instructions from a Majority, the Securityholders’ Representative shall comply with such instructions.

          (d) The Securityholders’ Representative shall not be liable to the Securityholders for any act taken or omitted to be taken as Securityholders’ Representative or for the selection of investments of the escrowed cash in the Indemnity Escrow Fund and the Securityholders’ Representative Fund and any interest or income earned thereon or for investment losses incurred thereon, except for the commission of actual fraud or willful misconduct. Each Securityholder shall severally indemnify the Securityholders’ Representative and hold the Securityholders’ Representative harmless against any damages or expenses incurred without bad faith on the part of the Securityholders’ Representative and arising out of or in connection with the acceptance or administration of the Securityholders’ Representative’s duties hereunder, including the reasonable fees and expenses of any legal counsel retained by the Securityholders’ Representative.

          (e) The power of attorney granted by the Company Indemnifying Parties and the Company Indemnified Parties to the Securityholders’ Representative pursuant to this Section 8.7 is coupled with an interest and is irrevocable and shall not terminate or otherwise be affected by the death, disability, incompetence, bankruptcy or insolvency of any Company Indemnifying Party or Company Indemnified Party.

          (f) The provisions of this Section 8.7 (or a reasonably detailed summary thereof) shall be distributed to the Securityholders prior to the Company Stockholders Meeting, and approval of the Merger and adoption of this Agreement by the Securityholders shall constitute ratification of the appointment of the Securityholders’ Representative and approval of the provisions of this Section 8.7.

83

     Section 8.8 Certain Tax Indemnification Matters; Contests.

          (a) Preparation of Tax Returns and Payment of Taxes.

               (i) Parent shall prepare (or cause to be prepared at Parent’s expense) and timely file all Tax Returns of the Company and its Subsidiaries required to be filed with any Governmental Entity after the Closing Date, and shall pay (or cause to be paid) any Taxes due in respect of such Tax Returns. With respect to any Tax Returns filed with respect to any taxable periods (or portions thereof) ending on or before the Closing Date (“Pre-Closing Taxable Periods”), the Company Indemnifying Parties shall be responsible for the Taxes of the Company and its Subsidiaries for all Pre-Closing Taxable Periods (“Pre-Closing Taxes”). Parent shall notify the Securityholders’ Representative and the Escrow Agent pursuant to the provisions of Section 8.4(a) with respect to any amounts for Taxes due from the Company Indemnifying Parties in respect of any such Tax Return, and the provisions of Section 8.4 shall apply with respect thereto.

               (ii) In the case of Tax Returns that are filed after the Closing Date with respect to taxable periods that end on or prior to the Closing Date, Parent shall prepare such Tax Returns in a manner consistent with past practice, except as otherwise required by Law. The Company Indemnifying Parties shall be responsible for all Pre-Closing Taxes with respect to any such Tax Returns. Parent shall deliver any such Tax Returns to the Securityholders’ Representative for review at least 30 days prior to the date such Tax Returns are required to be filed. If the Securityholders’ Representative disputes any item on any such Tax Return, the Securityholders’ Representative shall notify Parent of such disputed item (or items) and the basis for its objection. The parties shall act in good faith to resolve any such dispute prior to the date on which the relevant Tax Return is required to be filed.

               (iii) In the case of Tax Returns that are filed with respect to any taxable period that begins before and ends after the Closing Date (a “Straddle Period”), Parent shall prepare such Tax Returns (“Straddle Returns”) in a manner consistent with past practice, except as otherwise required by Law. The Company Indemnifying Parties shall be responsible for all Pre-Closing Taxes with respect to any Straddle Period (whether or not shown on any Straddle Return). Parent shall notify the Securityholders’ Representative and the Escrow Agent pursuant to the provisions of Section 8.4(a) with respect to any amounts due from the Company Indemnifying Parties in respect of any Pre-Closing Taxes with respect to any Straddle Period, and the provisions of Section 8.4 shall apply with respect thereto.

               (iv) From and after the Closing Date, the Parent Indemnifying Parties shall indemnify the Company Indemnifying Parties against, and hold them harmless from, any and all Damages arising out of any Taxes of the Post-Spin-Off Company Group for that portion of Taxes attributable to a Straddle Period that does not constitute Pre-Closing Taxes, other than amounts for which a Parent Indemnifying Party is indemnified by the Company Indemnifying Parties under Section 8.2(a).

84

               (v) For purposes of this Agreement, in the case of any Taxes of the Company or any of its Subsidiaries that are payable with respect to any Straddle Period, the portion of any such Taxes that constitutes Pre-Closing Taxes shall: (i) in the case of Taxes that are either (x) based upon or related to income or receipts, or (y) imposed in connection with any sale, transfer or assignment or any deemed sale, transfer or assignment of property (real or personal, tangible or intangible), be deemed equal to the amount that would be payable if the Tax year or period ended on the Closing Date; and (ii) in the case of Taxes (other than those described in clause (i) above) that are imposed on a periodic basis with respect to the business or assets of the Company or its Subsidiaries or otherwise measured by the level of any item, be deemed to be the amount of such Taxes for the entire Straddle Period (or, in the case of such Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding Tax period) multiplied by a fraction the numerator of which is the number of calendar days in the portion of the Straddle Period ending on the Closing Date and the denominator of which is the number of calendar days in the entire Straddle Period. For purposes of clause (i) of the preceding sentence, any exemption, deduction, credit or other item (including, without limitation, the effect of any graduated rates of tax) that is calculated on an annual basis shall be allocated to the portion of the Straddle Period ending on the Closing Date on a pro rata basis determined by multiplying the total amount of such item allocated to the Straddle Period times a fraction, the numerator of which is the number of calendar days in the portion of the Straddle Period ending on the Closing Date and the denominator of which is the number of calendar days in the entire Straddle Period. In the case of any Tax based upon or measured by capital (including net worth or long-term debt) or intangibles, any amount thereof required to be allocated under this Section 8.8 shall be computed by reference to the level of such items on the Closing Date. All determinations necessary to give effect to the foregoing allocations shall be made in a manner consistent with past practice of the Company and its Subsidiaries. The parties hereto will, to the extent permitted by applicable law, elect with the relevant Governmental Entity to treat a portion of any Straddle Period as a short taxable period ending as of the close of business on the Closing Date.

          (b) Control of Contests.

               (i) In the case of a Contest arising after the Closing Date but during the Escrow Period that relates solely to Taxes for which the Parent Indemnified Parties are indemnified under Section 8.2(a), Parent shall notify the Securityholders’ Representative thereof, who shall be entitled to control the conduct of such Contest, but the Parent Indemnified Parties shall have the right to participate in such Contest at their own expense, and the Securityholders’ Representative shall not be able to settle, compromise and/or concede any portion of such Contest that is reasonably likely to affect the Tax liability of any of the Surviving Corporation and its Subsidiaries for any taxable year (or portion thereof) beginning after the Closing Date without the reasonable consent of the Parent, which consent shall not be unreasonably withheld or delayed; provided, that, if the Securityholders’ Representative fails to assume control of the conduct of any such Contest within a reasonable period of time following the receipt by the Securityholders’ Representative of notice of such Contest, or if at the time the Escrow

85

Fund is not sufficient to cover the full amount of the Damages relating to such Contest (assuming the full amount thereof becomes payable to the Parent Indemnified Parties), then the Parent Indemnified Parties shall have the right to assume control of such Contest and shall be able to settle, compromise and/or concede such Contest in their sole discretion.

               (ii) In the case of a Contest arising after the Closing Date but during the Escrow Period that relates both to Taxes for which the Parent Indemnified Parties are indemnified under Section 8.2(a) and Taxes for which the Parent Indemnified Parties are not indemnified under Section 8.2(a), Parent shall notify the Securityholders’ Representative thereof, and the Parent Indemnified Parties shall be entitled to control the conduct of such Contest, but the Securityholders’ Representative shall have the right to participate in such Contest at its own expense, and the Parent Indemnified Parties shall not settle, compromise and/or concede such Contest without the consent of the Securityholders’ Representative, which consent shall not be unreasonably withheld or delayed; provided, that if at the time the Indemnity Escrow Fund is not sufficient to cover the full amount of the Damages relating to such Contest that may be payable to the Parent Indemnified Parties under this Article VIII (assuming the full amount of such Damages becomes payable to the Parent Indemnified Parties) (the “Full Contest Amount”) and either (i) the Full Contest Amount exceeds the then remaining value of the Indemnity Escrow Fund (excluding any portion thereof subject to a pending claim) by $3,500,000 or (ii) the remaining value of the Indemnity Escrow Fund (determined valuing Indemnity Escrowed Shares at the Closing Price and excluding any portion thereof already subject to a pending claim) is less than 50% of the Full Contest Amount, the Securityholders’ Representative shall no longer have the right to participate in such Contest and the Parent Indemnified Parties shall no longer be required to obtain the consent of the Securityholders’ Representative with respect to the settlement, compromise and/or concession of such Contest; provided that (a) such Contest is conducted in good faith and with due regard for the Securityholders’ interests and (b) the Securityholders’ Representative is kept reasonably informed of the progress of such Contest.

               (iii) After the Closing Date, except as provided in Section 8.8(b)(i) or Section 8.8(b)(ii), the Parent Indemnified Parties shall control the conduct, through counsel of their own choosing, of any Contest involving any asserted Tax liability or refund with respect to any of the Surviving Corporation and its Subsidiaries.

     Section 8.9 Limitation on Liability. In determining the amount of Taxes for any Pre-Closing Tax Period for which the Company Indemnifying Parties are required to indemnify the Parent Indemnified Parties pursuant to this Agreement, any net operating losses of the Company and its Subsidiaries at the time of Closing will be deemed to be available, even if those net operating losses have been utilized by the Parent Indemnified Parties in a taxable period ending before the Closing, but taking into account any limitations to which the utilization of such losses were subject immediately prior to the Closing.

86

     Section 8.10 Sole Remedy. From and after the Closing, the rights to indemnification provided for in this Article VIII shall be the exclusive remedy for money damages available to the parties with respect to the subject matter of this Agreement, except for claims of, or causes of action arising from, fraud or fraud-based claims.

ARTICLE IX

          (c) if the board of directors of the Company exempts any Person other than the Parent or any of its Affiliates from the provisions of Section 203 of the DGCL;

               (i) the Company is not then and has not been in breach of any of its obligations under Section 6.5;

               (ii) the board of directors of the Company shall have authorized the Company, subject to complying with the terms of this Agreement, to enter into a binding written agreement, that is conditioned upon the termination of this Agreement in accordance with its terms, concerning a transaction that constitutes a Superior Proposal and the Company notifies Parent in writing either that it has entered into or that it intends to enter into such an agreement, attaching the most current version of such agreement (including any amendments, supplements or modifications to such notice;

          B. Under the terms of the Merger Agreement, it is contemplated that certain Canadian stockholders of the Company will, immediately prior to the Merger, consummate a transaction (the “Canadian Transaction”) whereby such Canadian stockholders will exchange their shares for the Merger Consideration they would have received in respect of those shares pursuant to the Merger had they not sold their shares to Parent immediately prior to the Merger.

          C. The Merger Agreement provides, among other things, that each issued and outstanding share of common stock, par value $.001, of the Company (the “Company Common Stock”), will be converted into the right to receive the Merger Consideration (other than the Excluded Shares).

          D. At the Closing, Parent, the Securityholders’ Representative (as defined below) and Mellon Investor Services, or such other bank or trust company designated by Parent and reasonably approved by the Company, shall enter into (i) an Indemnity Escrow Agreement (the “Indemnity Escrow Agreement”), substantially in the form attached as Exhibit E to the Merger Agreement, (ii) a Warrant Escrow Agreement (the “Warrant Escrow Agreement”), substantially in the form attached as Exhibit F to the Merger Agreement, and (iii) a Securityholders’ Representative Fund Escrow Agreement (the “Securityholders’ Representative Fund Escrow Agreement”), substantially in the form attached as Exhibit G to the Merger Agreement.

          F. Upon the terms and subject to the conditions of this Agreement, each Participating Stockholder wishes to participate in the Canadian Transaction and surrender the Exchange Shares owned by it to Parent, and Parent wishes to acquire such Exchange Shares, in

exchange for the Merger Consideration such Participating Stockholder would have received under the terms of the Merger Agreement had such Participating Stockholder not consummated the transactions contemplated hereby and instead had their shares of Company Common Stock converted into the right to receive the Merger Consideration.

VOTING AGREEMENT

     VOTING AGREEMENT, dated as of December 11, 2004 (this “Agreement”), by and among Ivanhoe Energy Inc., a Yukon corporation (“Parent”), Ensyn Group Inc., a Delaware corporation (the “Company”), and ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇, Businessman (“RMF”).

RECITALS

     WHEREAS Parent and the Company are entering into an Agreement and Plan of Merger, dated as of the date hereof (as the same may be amended or modified from time to time in accordance with its terms, the “Merger Agreement”), which provides, among other things, for the merger of Merger Sub with and into the Company, with the Company as the surviving corporation (the “Merger”);

     WHEREAS, as of the date hereof, RMF is the direct or indirect record and beneficial holder of 46,611,725 common shares without par value of Parent (collectively, the “Shares” and, together with such additional Shares hereafter acquired by RMF whether by means of purchase, dividend, distribution or otherwise, “Owned Shares”), representing 27.47% of the outstanding common shares without par value of Parent and 23.64% on a fully diluted basis, including common shares issued as a result of the exercise of options issued and outstanding under Parent’s employee stock plans and other outstanding convertible securities of Parent; and

     WHEREAS, Parent and the Company have requested that RMF agree, and RMF has agreed, to enter into this Agreement, pursuant to which, among other things, the parties desire to set forth their agreement with respect to the voting of the Owned Shares by RMF in connection with the Merger, upon the terms and subject to the conditions set forth herein.

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained herein, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

     SECTION 1. Certain Definitions. Capitalized terms used and not otherwise defined herein shall have the respective meanings ascribed to them in the Merger Agreement as in effect on the date hereof.

     SECTION 2. Agreement to Vote. RMF agrees that at such time as Parent conducts a meeting of, or otherwise seeks a vote or consent of, its shareholders for the purpose of approving the issuance by Parent of common shares without par value of Parent (“Merger Shares”) in connection with the transactions contemplated by the Merger Agreement (the “Merger Share Issue Approval”), RMF shall vote, or provide a consent with respect to, the Owned Shares in favor of the Merger Share Issue Approval provided that RMF will be under no obligation to vote, or provide a consent with respect to, the Owned Shares in favor of the Merger Share Issue Approval if the Merger Share Issue Approval contemplates the issuance to the shareholders of the Company of more than 42,300,000 Merger Shares (as the same may be adjusted for any stock split, dividend, distribution, reclassification, recapitalization, combination or other change with respect to the Shares occurring prior to the Closing Date).

     SECTION 3. Covenants of RMF. RMF hereby covenants and agrees that, except as contemplated by this Agreement or the Merger Agreement, RMF shall not while this Agreement is in effect:

     SECTION 4. No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Parent or the Company any direct or indirect ownership or incidence of ownership of or with respect to any Owned Shares. All rights, ownership and economic benefits of and relating to the Owned Shares shall remain vested in and belong to RMF, and neither Parent nor the Company shall have any power or authority to direct RMF in the voting of any of the Owned Shares, except as otherwise provided herein.

     SECTION 5. Representations and Warranties of RMF. RMF represents and warrants to Parent and the Company as follows:

     (a) This Agreement has been duly and validly executed and delivered by RMF and, assuming the due authorization, execution and delivery by Parent and the Company, constitutes a legal, valid and binding obligation of RMF, enforceable against RMF in accordance with its terms (except in all cases as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, receivership, conservatorship, moratorium, or similar laws affecting the enforcement of creditors’ rights generally and except that the availability of the equitable remedy of specific performance or injunctive relief is subject to the discretion of the court before which any proceeding may be brought).

     (b) The execution and delivery of this Agreement by RMF does not, and the performance of this Agreement by RMF shall not, (i) conflict with or violate any law, rule, regulation, order, judgment or decree applicable to RMF or by which the Owned Shares are bound or affected or (ii) except with respect to any of the following as to which a consent or waiver has already been obtained, result in any breach of or constitute a default (or an event that with notice or lapse or time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or result in the creation of a lien or encumbrance on any of the Owned Shares pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, franchise or other instrument or obligation to which RMF is a party or by which

2

RMF or the Owned Shares are bound or affected, except, in the case of clauses (i) and (ii), for any such conflicts, violations, breaches, defaults or other occurrences which would not prevent or delay the performance by RMF of his obligations under this Agreement.

     (c) The execution and delivery of this Agreement by RMF does not, and the performance of this Agreement by RMF shall not, require any consent, approval, authorization or permit of, or filing with or notification to, any court or arbitrator or any Governmental Entity except for applicable requirements, if any, of the Exchange Act and except where the failure to obtain such consents, approvals, authorizations or permits, or to make such filings or notifications, would not prevent or delay the performance by RMF of his obligations under this Agreement.

     (d) As of the date hereof, RMF is, directly or indirectly, the beneficial owner of 46,611,725 Shares. The Shares are, and the Owned Shares will be, all of the securities of Parent owned, either of record or beneficially, by RMF and his immediate family members sharing the same residence on and as of the Closing Date and RMF owns no other rights or interests exercisable for or convertible into any securities of Parent. The Shares are, and the Owned Shares will be, owned free and clear of all security interests, liens, claims, pledges, options, rights of first refusal, limitations on RMF’s voting rights, charges and other encumbrances of any nature whatsoever. RMF has not appointed or granted any proxy that is inconsistent with this Agreement, which appointment or grant is still effective, with respect to the Owned Shares.

     SECTION 6. Termination. This Agreement shall terminate and no party shall have any rights or duties hereunder upon the earlier of (a) the day on which the Merger Agreement is terminated in accordance with its terms and (b) the Effective Time. Any such termination shall be without prejudice to liabilities arising hereunder before such termination.

     SECTION 7. Shareholder Capacity. Notwithstanding anything herein to the contrary, RMF has entered into this Agreement solely in RMF’s capacity as the beneficial owner of the Shares and nothing herein shall limit or affect any actions taken or omitted to be taken at any time by RMF in his capacity as an officer or director of Parent.

     SECTION 8. Non-Survival. The representations and warranties made herein shall terminate upon termination of this Agreement.

     SECTION 9. Miscellaneous.

     (a) Entire Agreement; Assignment. This Agreement constitutes the entire agreement among the parties with respect to the subject matter hereof and supersedes all other prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof. Except as provided in Section 3, the rights and obligations under this Agreement shall not be transferred by any party without the prior written consent of the other parties.

The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that he or she is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, partner, member, trustee, employee or agent of another Entity against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit if it shall be determined, pursuant to Section 2 of this Article SIXTH, that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Corporation; except that no indemnification shall be made in respect of any claim, issue or matter as to which any such person shall have been adjudged to be liable for negligence or misconduct in the performance of his or her duty to the Corporation unless and only to the extent that the Court of Chancery of the State of Delaware or the court in which such action or suit was brought shall determine upon application that despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery of the State of Delaware or such other court shall deem proper.

     (c) Indemnification for Expenses of Successful Defense. To the extent that (i) in the case of actions, suits or proceedings relating to acts or omissions occurring prior to July 1, 1997, any director, officer, employee or agent of the Corporation, or (ii) in the case of actions, suits or proceedings relating to acts or omissions occurring on or after such date, any present or former director or officer of this Corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsection a. or b. of this Section 1, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection therewith.

     2. Authorization. Any indemnification under subsection a. or b. of Section 1 of this Article SIXTH (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification is proper in the circumstances because the person whose conduct is at issue has met the applicable standard of conduct set forth in such subsection a. or b. Such determination shall be made, with respect to a person who is a director or officer of the Corporation at the time of such determination, (i) by a majority vote of the directors who were not parties to such action, suit or proceeding, even though less than a quorum, or (ii) by a committee of such directors designated by majority vote of such directors, even though less than a quorum, or (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (iv) by the stockholders.

     3. Expense Advance. Expenses (including attorneys’ fees) incurred by a present or former officer or director of the Corporation in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the Corporation in advance of the final disposition of such action, suit or proceeding as authorized in one of the manners provided in Section 2 of this Article SIXTH upon receipt of an undertaking by or on behalf of such person to repay such amount, if it shall ultimately be determined that he or she is not entitled to be indemnified by the Corporation as authorized in this Article SIXTH. Such expenses (including attorneys’ fees) incurred by other employees or agents of the Corporation may be so paid upon such terms and conditions, if any, as the Corporation deems appropriate.

     4. Nonexclusivity. The indemnification and advancement of expenses provided by, or granted pursuant to, the other Sections of this Article SIXTH shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any statute, by-law, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in an official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, partner, member, trustee, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

     5. Insurance. The Corporation shall have power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, partner, member, trustee, employee or agent of another Entity against any liability asserted against, and incurred by, him or her in any such capacity, or arising out of his or her status as such, whether or not the

3

Corporation would have the power to indemnify such person against such liability under the provisions of this Article SIXTH, or Section 145 of the Delaware General Corporation Law.

     6. “The Corporation”. For the purposes of this Article SIXTH, references to “the Corporation” shall include (i) the corporation surviving or resulting from a merger or consolidation to which this Corporation is a party but is not the resulting or surviving corporation, and (ii) to the extent that the board of directors of the resulting corporation so decides, any constituent corporation (including any constituent of a constituent) which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers and employees or agents if its separate existence had continued, so that any person who is or was a director, officer, employee or agent of such constituent corporation or is or was serving at the request of such constituent corporation as director, officer, partner, member, trustee, employee or agent of another Entity shall stand in the same position under the provisions of this Article SIXTH with respect to the resulting or surviving corporation as he or she would have had with respect such constituent corporation if its separate existence had continued.

     7. Other Indemnification. The Corporation’s obligation, if any, to indemnify any person who was or is serving at its request as a director, officer, partner, member, trustee, employee or agent of another Entity shall be reduced by any amount such person may collect as indemnification from such other Entity or from insurance.

     8. Other Definitions. For purposes of this Article SIXTH , references to “other enterprises” shall include employee benefit plans; references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to “serving at the request of the Corporation” shall include any service as a director, officer, employee or agent of the Corporation which imposes duties on, or involves services by, such person with respect to an employee benefit plan, its participants, or beneficiaries; and a person who acted in good faith and in a manner he or she reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the Corporation” as referred to in this Article SIXTH .

     9. Continuation of Indemnification. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article SIXTH shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, partner, member, trustee, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

     10. Amendment or Repeal. Neither the amendment or repeal of this Article SIXTH nor the adoption of any provision of this Amended and Restated Certificate of Incorporation inconsistent with this Article SIXTH shall reduce, eliminate or adversely affect any right or protection hereunder of any person in respect of any act or omission occurring prior to the effectiveness of such amendment, repeal or adoption.

     SEVENTH: No director shall be personally liable to the Corporation or any stockholder for monetary damages for breach of fiduciary duty as a director, except to the extent that

4

exculpation from liability is not permitted under the General Corporation Law of the state of Delaware as in effect when such breach occurred.

     B. Immediately prior to the Merger, it is contemplated under the Merger Agreement that Parent and certain Canadian stockholders of the Company will consummate a transaction whereby such stockholders will exchange their shares for the consideration they would have received in respect of those shares pursuant to the Merger had they not sold their shares to Parent immediately prior to the Merger (the “Canadian Transaction”).

     C. The Merger Agreement and the Canadian Exchange Agreement contemplate that the Indemnity Escrow Fund provided for herein, together with the Indemnity Escrowed Warrant Shares held in the Warrant Escrow Fund as provided under the Warranty Escrow Agreement, shall be (i) available to secure the indemnification obligations of the Securityholders under the Merger Agreement and (ii) held to secure the Company’s obligations to meet certain business development milestones, in accordance with the terms set forth in this Agreement, the Warrant Escrow Agreement and the Merger Agreement.

     D. Pursuant to the Merger and the Canadian Transaction, the Securityholders, as part of the consideration to be received for their shares of common stock of the Company, will receive shares of Parent Common Stock, a portion of which is to be deposited into the Indemnity Escrow Fund provided for hereby.

     For good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:

     2. Consent of Securityholders and Securityholders’ Representative; Appointment of Indemnity Escrow Agent. By virtue of the approval of the Merger Agreement by the stockholders of the Company, and pursuant to the Canadian Exchange Agreement, the

Securityholders have, without any further act of any Securityholder, consented to (i) the establishment of the Indemnity Escrow Fund and the Warrant Escrow Fund to provide the means for paying the indemnification obligations of the Securityholders under Article VIII of the Merger Agreement, (ii) the appointment of the Securityholders’ Representative as their representative for purposes of this Agreement and as attorney-in-fact and agent for and on behalf of each Securityholder with respect to the subject matter of this Agreement, and the taking by the Securityholders’ Representative of any and all actions and the making of any decisions required or permitted to be taken or made by them under this Agreement (including, without limitation, authorizing delivery of the Escrowed Shares or Escrowed Cash (as those terms are defined in Section 3(a)) and the Indemnity Escrowed Warrant Shares to a Parent Indemnified Party or objecting to such deliveries and any claims set forth in any Parent Indemnification Certificate (as defined in Section 6(a)(i)) (in each case, pursuant to the terms of this Agreement), and (iii) all of the other provisions set forth in this Agreement. The Securityholders’ Representative hereby agrees to act as the Securityholders’ representative in accordance with, and agrees to be bound by, the applicable terms of this Agreement, the Merger Agreement and the Securityholders’ Representative Fund Escrow Agreement. The Indemnity Escrow Agent hereby accepts appointment as Indemnity Escrow Agent and agrees to accept delivery of and hold the Indemnity Escrow Fund in escrow subject to the terms and conditions of this Agreement and the Merger Agreement.

     3. Indemnity Escrow.

     (a) Indemnity Escrow Fund. Pursuant to Section 2.2(a) of the Merger Agreement, at the Closing, Parent shall deposit with the Indemnity Escrow Agent on behalf of the Indemnity Fund Securityholders an original certificate, registered in the name of the Indemnity Escrow Agent, as escrow agent, representing the Indemnity Escrowed Shares (the “Initial Escrowed Shares”). If at any time during the Indemnity Escrow Period (as defined in Section 7(b) hereof) Parent shall issue or otherwise distribute additional shares of Parent Common Stock or other securities (including shares issued upon a stock split, stock dividend, stock distribution, reclassification, recapitalization, combination or similar change affecting the Parent Common Stock) in respect of the Initial Escrowed Shares or any other securities then held in the Indemnity Escrow Fund (the “New Shares,” and together with the Initial Escrowed Shares, the “Escrowed Shares”), Parent shall promptly deliver such New Shares to the Indemnity Escrow Agent. The Escrowed Shares, together with any cash proceeds from the sale of any Escrowed Shares pursuant to Section 8 and any income earned thereon (collectively, the “Escrowed Cash”), are referred to herein as the “Indemnity Escrow Fund.”

     (b) Cash Dividends and Distributions. Notwithstanding anything to the contrary contained herein, and as contemplated by Section 2.2(a) of the Merger Agreement, Parent shall not be required to deposit with the Indemnity Escrow Agent any cash dividends or cash distributions paid in respect of the Escrowed Shares but shall deliver such cash dividends or cash distributions directly to the Indemnity Fund Securityholders in accordance with each Indemnity Fund Securityholder’s Pro Rata Portion (for purposes of this Agreement, the term “Securityholder” contained in the definition of Pro Rata Portion in the Merger Agreement shall be replaced with “Indemnity Fund Securityholder”).

2

     (c) Investment. The Indemnity Escrow Agent shall invest and reinvest the Escrowed Cash in money market funds that invest primarily in short term U.S. Treasury securities, obligations of or guaranteed by the United States of America or any agency thereof, certificates of deposit or bankers acceptances issued by any national or state chartered bank having total assets of at least $500,000,000 with a maturity not later than one year from the date of investment, or such other investments as may be specified from time to time to the Indemnity Escrow Agent by written instructions of the Securityholders’ Representative. In no event shall the Indemnity Escrow Agent be liable for the selection of investments or for investment losses incurred thereon. In no event shall the Securityholders’ Escrow Agent be liable for the selection of investments or for investment losses incurred thereon, except as provided in Section 8.7 of the Merger Agreement.

     4. Pro Rata Portion; Voting; Valuation.

     (a) Pro Rata Portion. As provided in Article VIII of the Merger Agreement and the Canadian Exchange Agreement, the Securityholders shall indemnify and hold harmless each Parent Indemnified Party from and against certain Damages in accordance with the Merger Agreement. The Indemnity Escrow Fund (less any Excess Proceeds (as defined in Section 8(a) below) included therein) and the Indemnity Escrowed Warrant Shares shall be the exclusive sources for the satisfaction of these indemnity obligations of the Securityholders, subject to the limitations, and in the manner provided, in this Agreement, the Warrant Escrow Agreement and the Merger Agreement. Each Indemnity Fund Securityholder’s proportionate interest in the Indemnity Escrow Fund shall be equal to such Indemnity Fund Securityholder’s Pro Rata Portion. Immediately prior to any distribution pursuant to Section 7, the Indemnity Escrow Agent shall request and Parent shall provide to the Indemnity Escrow Agent a schedule setting forth, as of the date of such request, the name of each Indemnity Fund Securityholder and such Indemnity Fund Securityholder’s Pro Rata Portion; provided, however, that each such schedule shall be approved by the Securityholders’ Representative (which approval shall not be unreasonably withheld or delayed) prior to Parent delivering such schedule to the Indemnity Escrow Agent. The Indemnity Escrow Agent and Parent (after approval of such schedule by the Securityholders’ Representative) shall be entitled to rely conclusively on the information set forth in the schedule of the Indemnity Fund Securityholders’ Pro Rata Portions provided to the Indemnity Escrow Agent hereunder from time to time.

     (b) Voting. Each Indemnity Fund Securityholder shall have the right to direct the voting of such Securityholder’s Pro Rata Portion of Escrowed Shares, and Parent will cooperate with the exercise of such rights. As the record holder of the Escrowed Shares, the Indemnity Escrow Agent shall promptly deliver copies of all proxy solicitation materials to the Indemnity Fund Securityholders having a beneficial interest therein and shall vote such shares in accordance with the instructions of the Indemnity Fund Securityholders.

     (c) Valuation of Escrowed Shares and Indemnity Escrowed Warrant Shares. For purposes of determining the number of Escrowed Shares to be delivered out of the Indemnity Escrow Fund as provided in this Agreement (including, without limitation, pursuant to Sections 6(a)(i), 6(b)(ii) and 7) and the number of Indemnity Escrowed Warrant Shares as provided in Section 5, each share of Parent Common Stock shall be deemed to be valued at the Closing Price (as adjusted for any stock split, stock dividend, stock distribution, reclassification,

3

recapitalization, combination or similar change affecting the Parent Common Stock occurring after the Closing Price is established pursuant to Section 3.2(b) of the Merger Agreement), notwithstanding the then current market price of the Parent Common Stock.

     5. Indemnity Escrowed Warrant Shares.

     (a) Indemnity Payments. Indemnified Damages Payments (as defined in Section 6(d)) shall be made in both Escrowed Shares (and/or Escrowed Cash in accordance with Section 6(a)(ii)) and Indemnity Escrowed Warrant Shares. With respect to any Indemnified Damages Payment, the amount of such payment that will be paid from (x) the Indemnity Escrow Fund shall be determined as follows: the product of (i) the amount of the Indemnified Damages Payment for the particular indemnity claim and (ii) a fraction, (A) the numerator of which is the value of the Indemnity Escrow Fund determined as of the date that the calculation is being made and (B) the denominator of which is the value of (1) the Indemnity Escrow Fund plus (2) the remaining Indemnity Escrowed Warrant Shares, in each case determined as of the date that the calculation is being made, and (y) the Indemnity Escrowed Warrant Shares shall be determined as follows: the product of (i) the amount of the Indemnified Damages Payment for the particular indemnity claim and (ii) a fraction, (A) the numerator of which is the value of the remaining Indemnity Escrowed Warrant Shares on the date that the calculation is being made and (B) the denominator of which is the value of (1) the Indemnity Escrow Fund plus (2) the remaining Indemnity Escrowed Warrant Shares, in each case determined as of the date that the calculation is being made. The Escrowed Shares and Indemnity Escrowed Warrant Shares shall be valued as provided in Section 4(c) hereof. For the avoidance of doubt, the Excess Proceeds that may be included in the Indemnity Escrow Fund at any time shall not be included in any determination of the value of the Indemnity Escrow Fund for purposes of the foregoing calculations.

     (b) Distribution of Indemnity Escrow Fund. In connection with any distribution from the Indemnity Escrow Fund pursuant to Section 7 hereof to the Indemnity Fund Securityholders, a proportionate amount of the Indemnity Escrowed Warrant Shares shall be released (as provided in Section 6(c) of the Warrant Escrow Agreement) and shall no longer be available to satisfy indemnification claims under Article VIII of the Merger Agreement.

     (c) Notice to Warrant Escrow Agent. Prior to any payment or distribution pursuant to Sections 6, 7 or 9, the Indemnity Escrow Agent shall send written notice to the Warrant Escrow Agent (i) informing it of the pending payment or distribution and (ii) in the case of payment on an indemnification claim, stating (A) the name of the Parent Indemnified Party to be paid, (B) the value or number of Indemnity Escrowed Warrant Shares to be paid out or distributed and (C) the date such payment or distribution is to take place. If the Indemnity Escrow Agent and the Warrant Escrow Agent are the same entity, then a written record of such information shall be maintained in lieu of sending a written notice.

     6. Indemnification Claims Process.

     (a) Payment of Claims.

               (i) Parent may make an indemnification claim for Damages pursuant to Article VIII of the Merger Agreement by concurrently delivering to the Indemnity Escrow

4

Agent and the Securityholders’ Representative, at any time on or before 5:00 p.m. (EST) on the last day of the Indemnity Escrow Period, a certificate signed by an officer of Parent (a “Parent Indemnification Certificate”) that, with respect to such Damages, (A) describes in reasonable detail the facts and circumstances known to the Parent Indemnified Party that gave rise to such indemnification claim and the amount arising therefrom, and (B) if the amount of Damages exceeds the applicable deductible amount provided for in Section 8.2(c)(ii) of the Merger Agreement (after taking into account any other indemnification claims made by the Parent Indemnified Parties pursuant to Article VIII of the Merger Agreement) (the “Applicable Deductible Amount”), provides for a demand of payment of the amount (not to exceed in the aggregate for all such claims the maximum amount specified in Section 8.2(c)(iv) of the Merger Agreement) arising from such claims for Damages (minus, to the extent not yet exhausted, the applicable Deductible Amount) (the “Payable Damages”), such demand to be accompanied by a statement by Parent that the Parent Indemnified Parties have paid Damages which, on a cumulative basis with all prior Damages, exceed the Applicable Deductible Amount.

               (ii) Any delivery from the Indemnity Escrow Fund to be made to Parent pursuant to this Section 6 shall be made first using Escrowed Shares, to the extent a sufficient number of Escrowed Shares remains in the Indemnity Escrow Fund, and second, using Escrowed Cash; provided, however, that notwithstanding the foregoing, the Securityholders’ Representative shall have the sole and exclusive discretion to direct that such deliveries be made in Escrowed Cash in lieu of or in addition to Escrowed Shares, such direction to be delivered to the Indemnity Escrow Agent (with a copy to Parent) at least two Business Days prior to the earliest date such delivery may be made to Parent in accordance with this Agreement. For purposes of deliveries made to Parent under this Agreement, fractional shares shall be rounded up or down to the nearest whole number.

     (b) Objections to Claims; Settlements.

     (i) For a period of 30 days after receipt by the Indemnity Escrow Agent and the Securityholders’ Representative of a Parent Indemnification Certificate as provided in Section 6(a)(i), (A) the Securityholders’ Representative shall have the right to object in writing to the claim or claims (or part of any claim), including the amount of the Payable Damages, made in such Parent Indemnification Certificate and (B) if such Parent Indemnification Certificate contains a demand for payment, the Indemnity Escrow Agent shall make no delivery to Parent from the Indemnity Escrow Fund pursuant to Section 6(a)(i) hereof (other than as provided in Section 6(b)(ii)) unless the Indemnity Escrow Agent shall have received written authorization from the Securityholders’ Representative to make such delivery. After the expiration of such 30-day period, the Indemnity Escrow Agent shall, as promptly as practicable, deliver to Parent out of the Indemnity Escrow Fund, an amount of Escrowed Shares and/or Escrowed Cash (in the order of priority set forth in Section 6(a)(ii)) having an aggregate value (with respect to the Escrowed Shares, determined in accordance with Section 4(c)) equal to the amount of the Payable Damages set forth in such Parent Indemnification Certificate, less the value of the number of Indemnity Escrowed Warrant Shares being delivered by the Warrant Escrow Agent in accordance with Section 5(a) hereof and Section 6(b) of the Warrant Escrow Agreement; provided, however, that the Indemnity Escrow Agent shall not make any such payment or delivery if the Indemnity Escrow Agent receives, prior to the expiration of such 30-day period, a written statement from the Securityholders’ Representative stating that it objects to

5

any claim or claims (or part of any claim), including the amount of the Payable Damages, made in the Parent Indemnification Certificate. The Securityholders’ Representative shall concurrently deliver a copy of any such written statement to Parent. If the Securityholders’ Representative does not object in writing within such 30-day period, such failure to so object shall be an irrevocable acknowledgment by the Securityholders’ Representative on behalf of the Company Indemnifying Parties that the Parent Indemnified Parties identified in the Parent Indemnification Certificate are entitled to payment as specified herein in respect of the full amount of the claim for Payable Damages set forth in such Parent Indemnification Certificate containing a demand for payment; provided, however, that such failure to object shall not be construed as any admission of liability or responsibility by the Securityholders for any other purpose. Notwithstanding the foregoing, the Indemnity Escrow Agent shall, as promptly as practicable, make delivery from the Indemnity Escrow Fund in accordance with this Section 6(b)(i) to the extent authorized to do so by the Securityholders’ Representative with respect to Escrowed Shares and Escrowed Cash in an aggregate amount equal to the value of the amount of Payable Damages not disputed by the Securityholders’ Representative, less the value of the number of Indemnity Escrowed Warrant Shares being delivered by the Warrant Escrow Agent in accordance with Section 5 hereof and Section 6(b) of the Warrant Escrow Agreement.

               (ii) If the Securityholders’ Representative has consented to any settlement pursuant to Section 8.5 of the Merger Agreement, the provisions of Section 8.5(d) of the Merger Agreement shall apply with respect to the obligation of the Securityholders’ Representative to give notice to the Indemnity Escrow Agent (and the right of Parent to do so upon the failure of the Securityholders’ Representative). If the Securityholders’ Representative has consented to any such settlement, the Securityholders’ Representative shall have no authority to deliver a notice of objection pursuant to Section 6(b)(i) with respect to Payable Damages properly paid by Parent pursuant to such settlement, and upon receipt by the Indemnity Escrow Agent of notice of such settlement from either the Securityholders’ Representative or Parent, the Indemnity Escrow Agent shall, as promptly as practicable, make delivery from the Indemnity Escrow Fund in accordance with Section 6(b)(i), less the Indemnity Escrowed Warrant Shares being delivered by the Warrant Escrow Agent in accordance with Section 5 hereof and Section 6(b) of the Warrant Escrow Agreement.

     (c) Resolution of Conflicts; Arbitration.

               (i) If the Securityholders’ Representative timely objects in writing to any claim or claims (or part of any claim) for indemnification made in any Parent Indemnification Certificate, then the Securityholders’ Representative and Parent shall attempt in good faith to agree upon the rights of the respective parties with respect to each such claim within 30 days after the Indemnity Escrow Agent’s receipt of the Securityholders’ Representative’s written objection to the claim pursuant to Section 6(b)(i) (the “Negotiation Period”). If the Securityholders’ Representative and Parent should so agree during the Negotiation Period, then both parties shall prepare, sign and deliver to the Indemnity Escrow Agent, a memorandum setting forth such agreement. The Indemnity Escrow Agent shall be entitled to rely on any such memorandum and, if such agreement involves a payment to a Parent Indemnified Party (the “Negotiated Damages Amount”), shall make delivery of the Negotiated Damages Amount from the Indemnity Escrow Fund in accordance with Section 6(b)(i), less the

6

Indemnity Escrowed Warrant Shares being delivered by the Warrant Escrow Agent in accordance with Section 5 hereof and Section 6(b) of the Warrant Escrow Agreement.

               (ii) If no such agreement has been reached by the end of the Negotiation Period, then, unless the amount of the Damages at issue is the subject of a pending litigation involving a Third Party Claim (in which event, as provided in Section 8.6(b) of the Merger Agreement, arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration), either Parent or the Securityholders’ Representative may demand arbitration of the matters and in such event the matter shall be settled by arbitration as provided in Section 8.6 of the Merger Agreement. The written decision of the arbitrators as to the validity and amount of any claim in such Parent Indemnification Certificate and the related notice of objection shall be binding and conclusive upon the parties to this Agreement. Parent or the Securityholders’ Representative may deliver to the Indemnity Escrow Agent a copy of the decision of the arbitrators. Notwithstanding anything to the contrary in Section 6(b) hereof, the Indemnity Escrow Agent shall be entitled to act in accordance with such decision and, upon its receipt of a copy thereof, shall make or withhold payments out of the Indemnity Escrow Fund in accordance therewith and provide the notice to the Warrant Escrow Agent pursuant to Section 5(c).

     (d) Indemnified Damage Payments. A payment of Damages to a Parent Indemnified Party with respect to an indemnification claim pursuant to this Section 6 shall be referred to as an “Indemnified Damages Payment.”

     7. Release of Indemnity Escrow Fund.

     (a) [First Release Date. No later than 20 days following the earlier of (i) the date that Parent, the Company, EPIL or any of their Affiliates shall have entered into a definitive agreement with an unaffiliated third party (which for these purposes shall include a joint venture between or among any of the foregoing Persons and an unaffiliated third party that has at least a 10% economic interest in the joint venture) for the construction or use of an RTP™ Plant, (ii) the date that Parent or any of its Affiliates shall have commenced construction or use of an RTP™ Plant and (iii) the second anniversary of the Closing Date (such earlier date being the “First Release Date”), the Indemnity Escrow Fund shall terminate with respect to 50% of the Unencumbered Escrow Fund (as defined below), and such portion of the Unencumbered Escrow Fund shall be delivered as promptly as practicable thereafter to the Indemnity Fund Securityholders in accordance with each Indemnity Fund Securityholder’s Pro Rata Portion, calculated in accordance with Section 4(a) hereof. As soon as practicable (but in no event later than ten Business Days) after the occurrence of the events described in clause (i) or (ii) above, Parent and the Securityholders’ Representative shall deliver to the Indemnity Escrow Agent a certificate signed by both parties notifying the Indemnity Escrow Agent of the occurrence of such event. The term “Unencumbered Escrow Fund” shall mean Escrowed Shares and Escrowed Cash other than the number of Escrowed Shares and/or an amount of Escrowed Cash equal, in the aggregate, to the full amount of each claim for Payable Damages (less the value of the number of Indemnity Escrowed Warrant Shares that would be allocated for payment of such Payable Damages pursuant to Section 5(a)) specified in any Parent Indemnification Certificate

7

containing a demand for payment delivered to the Indemnity Escrow Agent on or before the First Release Date that remains unresolved as of the First Release Date.]¹

     (b) Expiration of Indemnity Escrow Fund. The Indemnity Escrow Fund shall remain in existence from the Closing Date until the Indemnity Escrow Termination Date (the “Indemnity Escrow Period”). Promptly upon expiration of the Indemnity Escrow Period, Parent and the Securityholders’ Representative shall deliver a certificate signed by both parties to the Indemnity Escrow Agent notifying it of such expiration.

As each claim described in clause (i) of the proviso in the preceding sentence is resolved, the Indemnity Escrow Agent shall deliver to the Indemnity Fund Securityholders all Escrowed Shares and Escrowed Cash then remaining in the Indemnity Escrow Fund and not required to satisfy such resolved claims or any remaining unresolved claims, subject to any obligation to distribute such Escrowed Shares and Escrowed Cash as requested by the Securityholders’ Representative pursuant to Section 7(c). In the event the Securityholders’ Representative’s actual fees incurred in resolving all unresolved claims as of the last day of the Indemnity Escrow Period is less than the Estimated Fees, the Indemnity Escrow Agent shall deliver to the Indemnity Fund Securityholders all Escrowed Shares and Escrowed Cash then remaining in the Indemnity Escrow Fund that was to be used for Estimated Fees, subject to any obligation to distribute such Escrowed Shares and Escrowed Cash as requested by the Securityholders’ Representative pursuant to Section 7(c).

the unpaid Securityholders’ Representative Expenses, the Securityholders’ Representative shall have the right to submit any such expenses for payment out of the Indemnity Escrow Fund and the Indemnity Escrowed Warrant Shares in accordance with the payment procedures set forth in Section 5(a) of the Securityholders’ Representative Fund Escrow Agreement, except that the certificate required to be delivered by the Securityholders’ Representative (the “Expense Certificate”) shall be delivered to the Indemnity Escrow Agent and the Warrant Escrow Agent instead of the Securityholders’ Escrow Agent. Upon timely receipt of an Expense Certificate requesting payment of an unpaid Securityholders’ Representative Expense, (i) the Indemnity Escrow Agent shall promptly pay out of the Indemnity Escrow Fund in accordance with the payment instructions set forth therein an amount of Escrowed Cash equal to the product of (A) the amount of the expense set forth in the Expense Certificate and (B) the fraction calculated in accordance with Section 5(a) and (ii) the Warrant Escrow Agent shall promptly pay out of the Indemnity Escrowed Warrant Shares in accordance with the payment instructions set forth therein an amount of Escrowed Cash equal to the product of (A) the amount of the expense set forth in the Expense Certificate and (B) the fraction calculated in accordance with Section 5(a).

     (d) Taxes. For tax reporting purposes, interest or other income earned from the investment of the Indemnity Escrow Fund or any portion thereof that is distributed by the Indemnity Escrow Agent to any Person pursuant to the terms of this Agreement shall be reported as allocated to such Person when paid to such Person.

     (e) Cash In Lieu of Fractional Shares; Cash Requests.

               (i) In lieu of fractional shares of Parent Common Stock otherwise distributable to the Indemnity Fund Securityholders pursuant to Section 7, the Indemnity Fund Securityholders shall be entitled to receive an amount of cash equal to the product obtained by multiplying (A) that fraction of a share of Parent Common Stock to which such holder would otherwise have been entitled to receive by (B) the Closing Price (as adjusted for any stock split, stock dividend, stock distribution, reclassification, recapitalization, combination or similar change affecting the Parent Common Stock occurring after the Closing Price is established pursuant to Section 3.2(b) of the Merger Agreement). In lieu of fractional shares of securities other than Parent Common Stock issued or issuable upon distribution of such securities from the Indemnity Escrow Fund, the Indemnity Escrow Agent shall make such distribution of cash as shall be agreed by the Securityholders’ Representative and Parent.

               (ii) If there is insufficient Escrowed Cash in the Indemnity Escrow Fund to make any cash payments pursuant to Section 7(e)(i), the Indemnity Escrow Agent may submit a written request (a “Cash Request”) to Parent for such cash amounts as soon as practicable after it becomes aware of the need for such cash amounts. Within five Business Days after the receipt of a Cash Request, Parent shall deposit with the Indemnity Escrow Agent sufficient funds to pay such cash amounts; provided, however, that Parent shall be reimbursed therefor pursuant to the following sentence. The Indemnity Escrow Agent shall deliver to Parent that number of Escrowed Shares corresponding to such cash amounts based on the Closing Price

9

(as adjusted for any stock split, stock dividend, stock distribution, reclassification, recapitalization, combination or similar change affecting the Parent Common Stock occurring after the Closing Price is established pursuant to Section 3.2(b) of the Merger Agreement) (provided, however, that fractional shares shall not be distributed to Parent until the aggregate of such fractional shares equals a whole number) and the Indemnity Escrow Fund shall be reduced by such number of Escrowed Shares.

     8. Sale of Escrowed Shares.

     (a) Sale Direction. From time to time during the Indemnity Escrow Period, a majority of the committee (the “Sales Committee”) comprised of (i) the Securityholders’ Representative, (ii) a representative designated by Credit Suisse First Boston Management Corporation and (iii) ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇ (each a, “Committee Member”), each of whom shall have an equal vote in the matter, may deliver to the Indemnity Escrow Agent a written direction (a “Sale Direction”) directing the Indemnity Escrow Agent to sell Escrowed Shares on the NASDAQ Small-Cap Market and deposit the sales proceeds thereof (net of any sales commissions or equivalent charges incurred in connection with such sale) (the “Net Sales Proceeds”) into the Indemnity Escrow Fund; provided, however, that (i) the per share Net Sales Proceeds of such Escrowed Shares shall not be less than the Minimum Sale Price (as defined below) and (ii) not more than 500,000 Escrowed Shares are sold during any five consecutive trading-day period and, in addition, not more than 1,500,000 Escrowed Shares are sold within any 20 consecutive trading-day period. A Sale Direction must be signed by at least two of the three Committee Members, and shall specify (x) the number of Escrowed Shares to be sold, (y) the minimum price per share at which such Escrowed Shares may be sold (which minimum price per share must result in per share Net Sales Proceeds equal to at least 105% of the Closing Price (as adjusted for any stock split, stock dividend, stock distribution, reclassification, recapitalization, combination or similar change affecting the Parent Common Stock occurring after the Closing Price is established pursuant to Section 3.2(b) of the Merger Agreement), such minimum price, the “Minimum Sale Price”), and (z) the trading days on which the Indemnity Escrow Agent must attempt to sell such Escrowed Shares (the “Sale Period”). At the time of delivery of any Sale Direction to the Indemnity Escrow Agent, the Securityholders’ Representative shall deliver a duplicate copy of such Sale Direction to Parent and to each other Committee Member. The Net Sales Proceeds of any sale of Escrowed Shares pursuant to this Section 7(a) shall be deposited by the Indemnity Escrow Agent into the Indemnity Escrow Fund; provided, however, that to the extent the per share Net Sales Proceeds of the Indemnity Escrowed Shares exceed the Closing Price (as adjusted for any stock split, stock dividend, stock distribution, reclassification, recapitalization, combination or similar change affecting the Parent Common Stock occurring after the Closing Price is established pursuant to Section 3.2(b) of the Merger Agreement) (such excess amount being referred to as the “Excess Proceeds”), such Excess Proceeds need not be deposited into the Indemnity Escrow Fund but may be paid to the Indemnity Fund Securityholders or, at the discretion of the Sales Committee, used to pay the Securityholders’ Representative’s fees listed in Section 9(b). None of the Committee Members shall be liable to the Indemnity Fund Securityholders for any action taken or omitted to be taken by him or her under this Section 8.

     (b) Initiation of Sale of Escrowed Shares. Upon receipt of a Sale Direction, the Indemnity Escrow Agent shall use commercially reasonable efforts to sell Escrowed Shares

10

in accordance with the instructions contained therein. Without limiting the generality of Section 10(g), in no event shall the Indemnity Escrow Agent be required to initiate the sale of any Escrowed Shares prior to the second trading day following the date of the Indemnity Escrow Agent’s receipt of the Sale Direction.

     (c) Sale Statement; Delivery of Excess Proceeds. Within two Business Days following the earlier to occur of (i) the date upon which the Indemnity Escrow Agent sells all of the Escrowed Shares that it has been directed to sell pursuant to a Sale Direction and (ii) the expiration of the applicable Sale Period, the Indemnity Escrow Agent shall deliver to the Securityholders’ Representative and to Parent a statement (a “Sale Statement”) setting forth (w) the total number of Escrowed Shares sold pursuant to the applicable Sale Direction, (x) the average per share Net Sales Proceeds, (y) the aggregate amount of any sales commissions or equivalent charges incurred in connection with the sale of such Escrowed Shares and (z) the aggregate Excess Proceeds. If neither the Securityholders’ Representative nor Parent objects to such Sale Statement within two Business Days of its receipt thereof, the Indemnity Escrow Agent shall pay, as promptly as practicable, such Excess Proceeds to the Indemnity Fund Securityholders.

     (d) All deliveries from the Indemnity Escrow Fund to the Indemnity Fund Securityholders under this Agreement (including deliveries of Excess Proceeds pursuant to Section 8(c)) shall be made in accordance with each Indemnity Fund Securityholder’s Pro Rata Portion.

     9. Securityholders’ Representative.

     (a) Removal. The Securityholders’ Representative may be changed in accordance with the terms of Section 8.7 of the Merger Agreement and the Securityholders’ Representative Fund Escrow Agreement. A Majority of the Securityholders shall notify the Indemnity Escrow Agent and Parent in writing of any such change and the Indemnity Escrow Agent and Parent shall be entitled to rely upon such notice without further inquiry.

     (b) Fees. No bond shall be required of the Securityholders’ Representative. The Securityholders’ Representative shall be entitled to receive a fee of $250.00 per hour for time spent fulfilling the Securityholders’ Representative Obligations. Any request by the Securityholders’ Representative for the payment of such fees shall be made by delivery of a request (the “Fee Request”) to the Indemnity Escrow Agent, the Warrant Escrow Agent and Parent, with a copy to the designated representative of Credit Suisse First Boston Management Corporation and ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇, that (i) specifies the amount of fees requested to be paid and (ii) describes in reasonable detail the Securityholders’ Representative Obligations performed for which fees are being requested. The fees specified in the Fee Request shall be paid proportionately out of the Indemnity Escrow Fund and the Indemnity Escrowed Warrant Shares (in accordance with the allocation methodology set forth in Section 5(a)), first, with respect to the Indemnity Escrow Fund, with Escrowed Cash and, if there is not a sufficient amount of Escrowed Cash, with Escrowed Shares, which, together with the Indemnity Escrowed Warrant Shares, shall be valued for purposes of this Section 9(b) at the Daily Closing Price on the trading day immediately preceding the date of payment of such fees. The fees specified in the Fee Request shall be paid to the Securityholders’ Representative promptly, but in no event later than

11

30 days, following receipt by the Indemnity Escrow Agent and Warrant Escrow Agent of written approval by Parent, such approval not to be unreasonably withheld or delayed.

     (c) Reliance. Notices or communications to or from the Securityholders’ Representative shall constitute notice to or from each of the Securityholders. A decision, act, consent or instruction of the Securityholders’ Representative shall constitute a decision of all Securityholders and shall be final, binding and conclusive upon each of such Securityholders, and the Indemnity Escrow Agent, Parent and all other Parent Indemnified Parties may rely upon any such decision, act, consent or instruction of the Securityholders’ Representative as being the decision, act, consent or instruction of each and every such Securityholder. The Indemnity Escrow Agent, Parent and all other Parent Indemnified Parties are hereby relieved from any liability to any person for any acts done by them in accordance with such decision, act, consent or instruction of the Securityholders’ Representative. The Securityholders’ Representative shall not be liable to the Securityholders for any act done or omitted hereunder as the Securityholders’ Representative except as provided in Section 8.7 of the Merger Agreement.

     10. Indemnity Escrow Agent.

     (a) Duties. The Indemnity Escrow Agent shall hold and safeguard the Indemnity Escrow Fund during the Indemnity Escrow Period, and shall hold and dispose of the Indemnity Escrow Fund only in accordance with the terms of this Agreement and with at least the same degree of care that it exercises with respect to its own similar property. The Indemnity Escrow Agent: (i) shall be obligated only for the performance of such duties as are specifically set forth in this Agreement; (ii) shall not be responsible for any of the agreements referred to or described herein (including the Merger Agreement or any of the exhibits thereto), or for determining or compelling compliance therewith, and shall not otherwise be bound thereby, except where such other agreement is referred to in this Agreement either (A) explicitly or (B) implicitly by use of a capitalized term not defined herein but defined therein; (iii) shall not be obligated to take any legal or other action hereunder which might in its reasonable judgment involve material expense or liability unless it shall have been furnished with indemnity reasonably acceptable to it; (iv) may rely on and shall be protected in acting or refraining from acting upon any written notice, instruction, instrument, statement, request or document furnished to it hereunder and reasonably believed by it to be genuine and to have been signed or presented by the proper person, and shall have no responsibility for determining the accuracy thereof; and (v) may consult counsel satisfactory to it, including in-house counsel, in respect of any action taken, suffered or omitted by it hereunder. Without limiting the generality of clause (iv) above, the Indemnity Escrow Agent shall be entitled to rely conclusively upon a Parent Indemnification Certificate (subject to the provisions of Section 6(b)) or any memorandum of agreement or written decision of arbitrators, as the case may be, for the number of Escrowed Shares and Indemnity Escrowed Warrant Shares and the amount of Escrowed Cash to be delivered pursuant to such instruments without any duty to verify or recalculate same.

     (b) Compliance with Orders. The Indemnity Escrow Agent is hereby expressly authorized to comply with and obey orders, judgments or decrees of any court or any written decision of arbitrators. If the Indemnity Escrow Agent obeys or complies with any such order, judgment or decree of any court or any written decision of arbitrators, the Indemnity Escrow Agent shall not be liable to any of the parties hereto or to any other person by reason of

12

such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction.

     (c) Reliance. The Indemnity Escrow Agent shall not be liable in any respect on account of the identity, authority or rights of the other parties executing or delivering or purporting to execute or deliver this Agreement or any documents or papers deposited or called for hereunder.

     (d) Indemnification. Neither the Indemnity Escrow Agent nor any of its directors, officers or employees shall be liable to anyone for any action taken or omitted to be taken by it or any of its directors, officers or employees hereunder except in the case of gross negligence, bad faith or willful misconduct. In no event shall the Indemnity Escrow Agent be liable for indirect, punitive, special or consequential damages or loss whatsoever. Parent and the Indemnity Fund Securityholders (collectively, the “Escrow Agent Indemnifying Parties”) shall, jointly and severally, indemnify the Indemnity Escrow Agent and hold it harmless from and against any fee, loss, liability or expense (including reasonable attorneys’ fees and expenses) (a “Loss”) incurred by the Indemnity Escrow Agent arising out of or in connection with the performance of its obligations in accordance with the provisions of this Agreement or with the administration of its duties hereunder, unless such Loss shall arise out of or be caused by the Indemnity Escrow Agent’s gross negligence, bad faith or willful misconduct; provided, however, that the Indemnity Escrow Fund shall be the exclusive source for the satisfaction by the Indemnity Fund Securityholders of the indemnity obligation set forth in this Section 10(d); provided, further, that the indemnity agreement contained in this Section 10(d) shall not apply to amounts paid in settlement of any Loss if such settlement is effected without the consent of the Securityholders’ Representative and Parent.

     (e) Contribution. Each of the Escrow Agent Indemnifying Parties shall contribute to the indemnification liability under this Section 10 in such proportion as is appropriate to reflect the relative fault of each individual Escrow Agent Indemnifying Party. In all cases where there is no such basis for allocating contribution for such indemnification liability, one half of the total of such indemnification liability shall be paid by Parent and one half of the total of such indemnification liability shall be paid out of the Indemnity Escrow Fund; provided, however, that if insufficient funds are available in the Indemnity Escrow Fund (the “Shortfall”) to pay such half, then Parent shall pay the amount of such Shortfall.

     (f) Resignation; Removal. The Indemnity Escrow Agent may (i) be removed by mutual consent of Parent and the Securityholders’ Representative, provided that the Warrant Escrow Agent and the Securityholders’ Escrow Agent are also so removed, and (ii) resign at any time, in each case, upon giving at least 30 days’ prior written notice to the Indemnity Escrow Agent or Parent and the Securityholders’ Representative, as applicable; provided, however, that no such resignation shall become effective until the appointment of a successor escrow agent, which shall be accomplished as follows: Parent and the Securityholders’ Representative shall use their best efforts to mutually agree upon a successor agent within 30 days after the applicable party receives, or parties receive, such notice. If the parties fail to agree upon a successor escrow agent within such time, the Securityholders’ Representative, with the consent of Parent, which shall not be unreasonably withheld, conditioned or delayed, shall have the right to appoint a

13

successor escrow agent. The successor escrow agent selected in the preceding manner shall execute and deliver an instrument accepting such appointment and becoming a party to this Agreement and it shall thereupon be deemed the Indemnity Escrow Agent hereunder and it shall without further acts be vested with all the estates, properties, rights, powers, and duties of the predecessor the Indemnity Escrow Agent as if originally named as the Indemnity Escrow Agent. If no successor escrow agent is named, the Indemnity Escrow Agent may apply to a court of competent jurisdiction for the appointment of a successor escrow agent. Thereafter, the predecessor Indemnity Escrow Agent shall be discharged from any further duties and liabilities under this Agreement. If the Indemnity Escrow Agent is removed pursuant to clause (i) above, Parent and the Securityholders’ Representative shall appoint a successor escrow agent in accordance with the procedure set forth in clause (ii) above, provided that the successor escrow agent is the same as the successor escrow agent appointed under the Warrant Escrow Agreement and the Securityholders’ Representative Fund Escrow Agreement. The provisions of Section 9(d) shall survive the resignation or removal of the Indemnity Escrow Agent or the termination of this Agreement. Nothing in this Section 10(f) shall affect Parent’s right under Section 8(g) of the Warrant Escrow Agreement.

     (g) Distribution of Indemnity Escrow Fund. Notwithstanding any term appearing in this Agreement to the contrary, in no instance shall the Indemnity Escrow Agent be required or obligated to distribute any of the Indemnity Escrow Fund (or take other action that may be called for hereunder to be taken by the Indemnity Escrow Agent) sooner than two Business Days after (i) it has received the applicable documents required under this Agreement or (ii) passage of the applicable time period (or both, as applicable under the terms of this Agreement), as the case may be.

     (h) Disputes. Should any dispute arise with respect to the delivery, ownership, right of possession, and/or disposition of the Indemnity Escrow Fund, or should any claim be made upon the Indemnity Escrow Agent or the Indemnity Escrow Fund by a third party, the Indemnity Escrow Agent upon receipt of notice of such dispute or claim is authorized and shall be entitled (at its sole option and election) to retain in its possession without liability to anyone, the portion of the Indemnity Escrow Fund in dispute until such dispute shall have been settled either by the mutual written agreement of the parties involved or by a final order, decree or judgment of a court in the United States of America, the time for perfection of an appeal of such order, decree or judgment having expired. The Indemnity Escrow Agent may, but shall be under no duty whatsoever to, institute or defend any legal proceedings which relate to the Indemnity Escrow Fund.

     (i) Transfer Agent. The Indemnity Escrow Agent shall deliver to Mellon Investor Services (the “Transfer Agent”) the original stock certificates representing Escrowed Shares, together with appropriate instructions, whenever the Indemnity Escrow Agent is to disburse Escrowed Shares, whether in payment of a claim or to the Indemnity Fund Securityholders, under the terms hereof. The Indemnity Escrow Agent shall not be liable for the actions or inaction of the Transfer Agent provided the Indemnity Escrow Agent has given the Transfer Agent instructions which conform to the terms hereof. Parent shall cause the Transfer Agent to issue to the Indemnity Escrow Agent stock certificates representing the Escrowed Shares remaining in the Indemnity Escrow Fund upon a distribution of the Escrowed Shares and

14

to issue stock certificates in the name of the Indemnity Fund Securityholders, as instructed by the Securityholders’ Representative.

     (j) Fees and Expenses. Parent and the Indemnity Fund Securityholders shall pay or reimburse the Indemnity Escrow Agent for its normal services hereunder. Such fees shall be shared equally by Parent and the Indemnity Fund Securityholders. The Indemnity Escrow Agent shall satisfy the Indemnity Fund Securityholders’ portion of such reimbursement obligation solely from the Indemnity Escrow Fund.

     (k) Periodic Statements. Within ten days following the end of each month, the Indemnity Escrow Agent shall provide to Parent and the Securityholders’ Representative [monthly][quarterly] statements identifying transactions, transfers or holdings of the Indemnity Escrow Fund. Each [monthly][quarterly] statement shall be deemed to be correct and final upon receipt thereof by Parent and the Securityholders’ Representative unless either one notifies the Indemnity Escrow Agent and the other party in writing to the contrary within 30 days of the date of such statement.

     11. Miscellaneous.

     (a) Amendments and Waivers. Any term of this Agreement may be amended or waived only with the written consent of Parent, the Securityholders’ Representative and the Indemnity Escrow Agent.

     WARRANT ESCROW AGREEMENT, dated as of _____________, 2005 (this “Agreement”), by and among IVANHOE ENERGY INC., a Yukon corporation (“Parent”), ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇ (the “Securityholders’ Representative”) and MELLON INVESTOR SERVICES, a _____________, as escrow agent (the “Warrant Escrow Agent”).

RECITALS

     A. Parent, Ivanhoe Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub”), and Ensyn Group, Inc., a Delaware corporation (the “Company”), have entered into an Agreement and Plan of Merger, dated as of December 11, 2004 (the “Merger Agreement”), pursuant to which Parent will acquire the Company through the merger (the “Merger”) of Merger Sub with and into the Company with the Company as the surviving corporation.

     B. Immediately prior to the Merger, it is contemplated under the Merger Agreement that Parent and certain Canadian stockholders of the Company will consummate a transaction whereby such stockholders will exchange their shares for the consideration they would have received in respect of those shares pursuant to the Merger had they not sold their shares to Parent immediately prior to the Merger (the “Canadian Transaction”).

     C. As of the Effective Time of the Merger, each Company Warrant shall be converted, by virtue of the Merger and without any action on the part of the holder of that Company Warrant, into a warrant exercisable for the Merger Consideration that such holder would have been entitled to receive had such holder exercised the Company Warrant immediately prior to the Closing Date.

     D. The Merger Agreement and the Canadian Exchange Agreement contemplate that the Warrant Escrow Fund provided for herein shall (i) be available to pay the Merger Consideration to holders of Company Warrants that exercise their Company Warrants after the Closing Date and (ii) to the extent not all Company Warrants are exercised prior to their expiration or termination, be payable pursuant to Participation Rights to the Securityholders entitled to receive Merger Consideration pursuant to the Merger Agreement and the Canadian Exchange Agreement, and upon exercise of Company Warrants.

     E. Pursuant to the Merger and the Canadian Transaction, the Securityholders will receive shares of Parent Common Stock, a cash payment and Participation Rights. The aggregate Merger Consideration consisting of Parent Common Stock and cash to be issued upon exercise of all Company Warrants outstanding as of the Closing Date is to be deposited into the Warrant Escrow Fund provided for hereby.

     F. The Merger Agreement and the Canadian Exchange Agreement contemplate that the portion of the Warrant Escrow Fund provided for herein that consists of Indemnity Escrowed Warrant Shares, together with the Indemnity Escrow Fund under the Indemnity Escrow Agreement, shall be (i) available to secure the indemnification obligations of the Securityholders under the Merger Agreement and (ii) held to secure the Company’s obligations to meet certain business development milestones, in accordance with the terms set forth in this Agreement, the Merger Agreement and the Indemnity Escrow Agreement.

           G. The parties desire to establish the terms and conditions pursuant to which the Warrant Escrow Fund will be established and maintained.

     For good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:

     1. Defined Terms. Capitalized terms used in this Agreement and not otherwise defined herein shall have the respective meanings given to them in the Merger Agreement.

     2. Consent of Securityholders and Securityholders’ Representative; Appointment of Warrant Escrow Agent. By virtue of the approval of the Merger Agreement by the stockholders of the Company, and pursuant to the Canadian Exchange Agreement, the Securityholders have, without any further act of any Securityholder, consented to (i) the establishment of the Warrant Escrow Fund to secure the payment of the Merger Consideration to holders of Company Warrants that exercise their Company Warrants after the Closing Date and, to the extent not all Company Warrants are exercised prior to their expiration or termination, to provide for the payment to the Securityholders of their Participation Rights, (ii) the appointment of the Securityholders’ Representative as their representative for purposes of this Agreement and as attorney-in-fact and agent for and on behalf of each Securityholder with respect to the subject matter of this Agreement, and the taking by the Securityholders’ Representative of any and all actions and the making of any decisions required or permitted to be taken or made by them under this Agreement (including, without limitation, authorizing delivery of the Indemnity Escrowed Warrant Shares to a Parent Indemnified Party pursuant to the terms of this Agreement and the Indemnity Escrow Agreement) and (iii) all of the other provisions set forth in this Agreement. The Securityholders’ Representative hereby agrees to act as the Securityholders’ representative in accordance with, and agrees to be bound by, the applicable terms of this Agreement, the Merger Agreement and the Securityholders’ Representative Fund Escrow Agreement. The Warrant Escrow Agent hereby accepts appointment as Warrant Escrow Agent and agrees to accept delivery of and hold the Warrant Escrow Fund in escrow subject to the terms and conditions of this Agreement, the Merger Agreement, the Indemnity Escrow Fund and the Securityholders’ Representative Fund Escrow Agreement.

     3. Warrant Escrow.

           (a) Warrant Escrow Fund. Pursuant to Section 2.2(b) of the Merger Agreement, at the Closing, Parent shall deposit with the Warrant Escrow Agent on behalf of the Securityholders the Escrowed Warrant Consideration, which shall consist of shares of Parent Common Stock (other than fractional shares of Parent Common Stock, in lieu of which cash shall be paid into the Warrant Escrow Fund) and cash (such cash, together with any cash deposited into the Warrant Escrow Fund in lieu of fractional shares of Parent Common Stock, being the “Initial Escrowed Cash”). At the Closing, Parent shall deposit with the Warrant Escrow Agent an original certificate, registered in the name of the Warrant Escrow Agent, as escrow agent, representing such Parent Common Stock (the “Initial Escrowed Warrant Shares”). From time to time during the Warrant Escrow Period (as defined in Section 3(d) hereof), Parent shall deposit with the Warrant Escrow Agent, as promptly as practicable, (i) any additional shares of Parent Common Stock or other securities issued or distributed by Parent (including shares issued upon a stock split, stock dividend, stock distribution, reclassification, recapitalization, combination or similar change affecting the Parent Common Stock) in respect of the Initial Escrowed Warrant Shares or any other securities then held in the Warrant Escrow

2

Fund (the “New Warrant Shares,” and together with the Initial Escrowed Warrant Shares, the “Escrowed Warrant Shares”), (ii) any cash dividends or other cash distributions paid by Parent in respect of the Escrowed Warrant Shares (“Cash Distributions”) and (iii) the cash exercise price paid by any holder of a Company Warrant who exercises such holder’s Company Warrant after the Closing Date (such cash exercise prices paid, together with the Initial Escrowed Cash and any Cash Distributions, being the “Warrant Escrowed Cash”). The Escrowed Warrant Shares and the Warrant Escrowed Cash are referred to herein as the “Warrant Escrow Fund.”

           (b) Investment. The Warrant Escrowed Cash shall not be invested.

           (c) Warrant Escrow Period. The Warrant Escrow Fund shall remain in existence from the Closing Date until the date that all Company Warrants have been exercised, have expired or have otherwise terminated, and all Participation Rights, if any, have been paid (the “Warrant Escrow Period”). For purposes of this Agreement (including, without limitation, Section 5), no Company Warrant shall be deemed to have expired or terminated (including Company Warrant Agreements Nos. 1 through 20) unless (i) such Company Warrant has an express maturity date or (ii) the holder of such Company Warrant provides a written acknowledgement of the expiration or termination of such Company Warrant to Parent and the Securityholders’ Representative.

     4. Participation Rights; Voting; Valuation.

           (a) Participation Rights. Each Securityholder shall have Participation Rights in the Warrant Escrow Fund equal to such Securityholder’s Pro Rata Portion. For the avoidance of doubt, a holder of Company Warrants who exercises such Company Warrants after the Closing Date and thereby becomes a Securityholder shall be entitled to such holder’s Pro Rata Portion of any distribution made pursuant to Section 5(c)(i) (including any distribution made before such holder exercised its Company Warrants) that would have been payable in respect of such holder’s Company Warrants had they been exercised immediately prior to the Closing Date. Immediately prior to any distributions of the Warrant Escrow Fund pursuant to Sections 5(c)(i) or 5(d), the Warrant Escrow Agent shall request and Parent shall provide to the Warrant Escrow Agent a schedule setting forth, as of the date of such request, the name of each Securityholder and such Securityholder’s Pro Rata Portion; provided, however, that each such schedule shall be approved by the Securityholders’ Representative (which approval shall not be unreasonably withheld or delayed) prior to Parent delivering such schedule to the Warrant Escrow Agent. The Warrant Escrow Agent and Parent (after approval of such schedule by the Securityholders’ Representative) shall be entitled to rely conclusively on the information set forth in the schedule of Securityholders’ Pro Rata Portions provided to the Warrant Escrow Agent hereunder from time to time.

           (b) Voting. Parent shall have the right to direct the voting of the Escrowed Warrant Shares.

           (c) Valuation of Escrowed Warrant Shares. For purposes of determining the value of Escrowed Warrant Shares held in the Warrant Escrow Fund, each share of Parent Common Stock constituting an Escrowed Warrant Share shall be deemed to be valued at the Closing Price (as adjusted for any stock splits, stock dividends, stock distributions, reclassifications, recapitalizations, combinations or similar changes affecting the Parent

3

Common Stock occurring after the Closing Price is established pursuant to Section 3.2(b) of the Merger Agreement), notwithstanding the then current market price of the Parent Common Stock.

     5. Distributions. Subject to Section 6 and Section 8(b) hereof, the Warrant Escrow Fund (not including the Indemnity Escrowed Warrant Shares) shall be distributed as follows:

           (a) Notice of Exercise of Company Warrant. Within two Business Days of receipt by Parent or the Company of a notice from a holder of Company Warrants exercising one or more Company Warrants, Parent or the Company, as the case may be, shall provide a copy of such notice to the other and to the Securityholders’ Representative. Upon the determination by Parent and the Securityholders’ Representative that the exercise of such Company Warrants is valid (which determination as to validity shall be made within ten Business Days after such notice is received by the Securityholders’ Representative, or at such earlier time as may be required to comply with the terms of such Company Warrants), Parent and the Securityholders’ Representative shall deliver to the Warrant Escrow Agent a certificate signed by an officer of Parent and the Securityholders’ Representative (a “Joint Certificate”) (i) stating that one or more Company Warrants have been duly exercised, (ii) stating the exercise price(s) with respect thereto and (iii) providing instructions for the delivery of the Merger Consideration payable to such holder of the exercised Company Warrants (less any Indemnity Escrowed Warrant Shares if the Company Warrant is exercised prior to the Indemnity Escrow Termination Date).

           (b) Delivery of Merger Consideration. Upon receipt by the Warrant Escrow Agent of (i) a Joint Certificate pursuant to Section 5(a) and (ii) the full amount of the exercise price payable in respect of the Company Warrants described in the Joint Certificate, the Warrant Escrow Agent shall (A) deposit the aggregate exercise price so received into the Warrant Escrow Fund and (B) deliver to the holder of each Company Warrant that has so exercised Company Warrants, from the Warrant Escrow Fund, (x) the Merger Consideration payable with respect to each Company Warrant so exercised (less any Indemnity Escrowed Warrant Shares if the Company Warrant is exercised prior to the Indemnity Escrow Termination Date) and (y) such holder’s Pro Rata Portion of any distribution previously made pursuant to Section 5(c)(i).

           (c) Release of Excess Warrant Escrow Fund.

               (i) Parent and the Securityholders’ Representative shall deliver a Joint Certificate to the Warrant Escrow Agent within ten Business Days following the end of each calendar [month][quarter], stating the aggregate maximum amount of Escrowed Warrant Consideration that may be payable in respect of all Company Warrants outstanding as of the end of such [month][quarter] (including the portion of any distributions made pursuant to this Section 5(c)(i) relating to any unexercised Company Warrants to be held in the Warrant Escrow Fund) (the “Remaining Warrant Merger Consideration”). If as of such [month][quarter] end the value of the Warrant Escrow Fund (not including the value of the Indemnity Escrowed Warrant Shares) exceeds the value of the Remaining Warrant Merger Consideration (not including the value of the Indemnity Escrowed Warrant Shares) by $50,000 or more, the Warrant Escrow Agent shall deliver to the Securityholders, in accordance with their respective Pro Rata Portions, as promptly as practicable, Escrowed Warrant Shares and Warrant Escrowed Cash, in the relative amounts set forth in Section 5(c)(ii), having an aggregate value equal to the aggregate value of the assets in the Warrant Escrow Fund (not including the Indemnity Escrowed Warrant Shares) minus the Remaining Warrant Merger Consideration. If as of each anniversary date of the Closing Date, the value of the Warrant Escrow Fund (not including the value of the

4

Indemnity Escrowed Warrant Shares) exceeds the value of the Remaining Warrant Merger Consideration by $10,000 or more, the Warrant Escrow Agent shall deliver to the Securityholders, in accordance with their respective Pro Rata Portions, as promptly as practicable, Escrowed Warrant Shares and Warrant Escrowed Cash, in the relative amounts set forth in Section 5(c)(ii), having an aggregate value equal to the aggregate value of the assets in the Warrant Escrow Fund (not including the Indemnity Escrowed Warrant Shares) minus the Remaining Warrant Merger Consideration. Notwithstanding the foregoing, (A) a portion of any distribution from the Warrant Escrow Fund made pursuant to this Section 5(c)(i) equal to the Pro Rata Portion that would have been payable to holders of then-unexercised Company Warrants had such Company Warrants been exercised immediately prior to the Closing Date shall be retained by the Warrant Escrow Agent in the Warrant Escrow Fund, such Pro Rata Portions to be delivered to holders of such unexercised Company Warrants upon the exercise thereof and (B) any distribution of Escrowed Warrant Shares and/or Warrant Escrowed Cash to Securityholders pursuant to this Section 5(c)(i) shall be subject to, and shall not be made prior to, any distribution of all or a portion of such Escrowed Warrant Shares and Warrant Escrowed Cash required to be made to the Securityholders’ Representative pursuant to Section 6(d).

               (ii) Any distribution from the Warrant Escrow Fund to Securityholders pursuant to Section 5(c)(i) shall consist of a combination of Escrowed Warrant Shares and Warrant Escrowed Cash such that, to the extent possible, it is ensured that a number of Escrowed Warrant Shares and an amount of Warrant Escrowed Cash necessary to satisfy any Remaining Warrant Merger Consideration shall remain in the Warrant Escrow Fund.

     (d) Termination of Warrant Escrow Fund. Promptly upon the occurrence thereof, Parent and the Securityholders’ Representative shall deliver a Joint Certificate to the Warrant Escrow Agent notifying the Warrant Escrow Agent of (i) the date that all Company Warrants have been exercised, have expired or have terminated or (ii) the occurrence of a Change of Control affecting Parent. Upon receipt by the Warrant Escrow Agent of a Joint Certificate stating that either of such events has occurred, the Warrant Escrow Agent shall deliver, as promptly as practicable, the Escrowed Warrant Shares (other than Indemnity Escrowed Warrant Shares, if any, which shall remain in the Warrant Escrow Agreement in order to be used to satisfy indemnification obligations under Article VIII of the Merger Agreement as provided in Section 6) and Warrant Escrowed Cash to the Securityholders, in each case, in accordance with their respective Pro Rata Portions, and the Warrant Escrow Fund shall terminate; provided, however, that any distribution of the Escrowed Warrant Shares and Warrant Escrowed Cash to Securityholders pursuant to this Section 5(d) shall be subject to, and shall not be made prior to, any distribution of all or a portion of such Escrowed Warrant Shares and Warrant Escrowed Cash required to be made to the Securityholders’ Representative pursuant to Section 6(d). Thereafter, assuming the Warrant Escrow Fund terminates pursuant to Section 5(d)(ii), each holder of unexercised Company Warrants shall look only to Parent for payment of any claim for Merger Consideration.

     (e) Cash in Lieu of Fractional Shares; Cash Requests.

               (i) In lieu of fractional shares of Parent Common Stock otherwise distributable to the Securityholders pursuant to this Section 5, the Securityholders shall be entitled to receive an amount of cash equal to the product obtained by multiplying (A) that fraction of an Escrowed Warrant Share to which such Securityholder would otherwise have been entitled to receive by (B) the Closing Price (as adjusted for any stock splits, stock dividends,

5

stock distributions, reclassifications, recapitalizations, combinations or similar changes affecting the Parent Common Stock occurring after the Closing Price has been established pursuant to Section 3.2(b) of the Merger Agreement). In lieu of fractional shares of securities other than Parent Common Stock issued or issuable upon distribution of such securities from the Warrant Escrow Fund, if any, the Warrant Escrow Agent shall make such distribution of cash as shall be agreed by the Securityholders’ Representative and Parent.

               (ii) If there is insufficient Warrant Escrowed Cash in the Warrant Escrow Fund to make any cash payments pursuant to Section 5(e)(i), the Warrant Escrow Agent may submit a written request (a “Cash Request”) to Parent for such cash amounts as soon as practicable after it becomes aware of the need for such cash amounts. Within five Business Days after the receipt of a Cash Request, Parent shall deposit with the Warrant Escrow Agent sufficient funds to pay such cash amounts; provided, however, that Parent shall be reimbursed therefor pursuant to the following sentence. The Warrant Escrow Agent shall deliver to Parent that number of Escrowed Warrant Shares corresponding to such cash amounts based on the Closing Price (as adjusted for any stock splits, stock dividends, stock distributions, reclassifications, recapitalizations, combinations or similar changes affecting the Parent Common Stock occurring after the Closing Price has been established pursuant to Section 3.2(b) of the Merger Agreement) (provided, however, that fractional shares shall not be distributed to Parent until the aggregate of such fractional shares equals a whole number) and the Warrant Escrow Fund shall be reduced by such number of Escrowed Warrant Shares.

     (f) Taxes. Each Securityholder shall be responsible for his, her or its Pro Rata Portion for all Taxes resulting from any distributions to such Securityholder of the Warrant Escrow Fund pursuant to this Agreement. Any amounts paid out of the Warrant Escrow Fund to any Securityholder that is treated as interest for United States federal income Tax purposes under the Code shall be deemed paid first by any Warrant Escrow Cash paid to the Securityholder out of the distribution made to the Securityholder.

6. Indemnity Escrowed Warrant Shares

     (a) Indemnification Obligations. As provided in Article VIII of the Merger Agreement and the Canadian Exchange Agreement, the Securityholders shall indemnify and hold harmless each Parent Indemnified Party from and against certain Damages in accordance with the Merger Agreement. The Indemnity Escrow Fund (less any Excess Proceeds (as defined in the Indemnity Escrow Agreement) included therein) and the Indemnity Escrowed Warrant Shares shall be the exclusive sources for the satisfaction of these indemnity obligations of the Securityholders, subject to the limitations, and in the manner provided, in this Agreement, the Indemnity Escrow Agreement and the Merger Agreement.

     (b) Notice of Indemnification Claim Payment. After receipt by the Warrant Escrow Agent of a written notice from the Indemnity Escrow Agent specifying (i) that payment of an indemnification claim for Damages is to be properly paid, (ii) the name of Parent Indemnified Party that is to be paid, (iii) the value or number of Indemnity Escrowed Warrant Shares to be paid with respect to such Indemnified Damages Payment (as defined in Section 6(d) of the Indemnity Escrow Agreement and as calculated pursuant to Section 5(a) thereof) and (iv) the date payment is to take place (unless such written notice has been dispensed because the Indemnity Escrow Agent and the Warrant Escrow Agent are the same entity), the Warrant

6

Escrow Agent shall deliver the appropriate number of Indemnity Escrowed Warrant Shares to the Parent Indemnified Party on the appointed date.

     (c) Notice of Release or Termination. After receipt by the Warrant Escrow Agent of a written notice from the Indemnity Escrow Agent specifying that a portion of the assets of the Indemnity Escrow Fund has been released pursuant to Section 7(a) of the Indemnity Escrow Agreement or that the Indemnity Escrow Fund has terminated pursuant to Section 7(b) of the Indemnity Escrow Agreement (unless such written notice has been dispensed because the Indemnity Escrow Agent and the Warrant Escrow Agent are the same entity), (i) in the case of a release of a portion of the assets of the Indemnity Escrow Fund, 50% of the Indemnity Escrowed Warrant Shares remaining in the Warrant Escrow Fund (other than the number of Indemnity Escrowed Warrant Shares that would be allocated for payment of any then-unresolved claims for Payable Damages (as defined in the Indemnity Escrow Agreement), if any, as provided in Section 7(a) of the Indemnity Escrow Agreement) shall cease to be classified as “Indemnity Escrowed Warrant Shares” and shall no longer be used to satisfy any indemnification claim of Parent under Article VIII of the Merger Agreement, or (ii) in the case of the termination of the Indemnity Escrow Fund, 100% of the Indemnity Escrowed Warrant Shares remaining in the Warrant Escrow Fund (other than the number of Indemnity Escrowed Warrant Shares that would be allocated for payment of (A) any then-unresolved claims for Payable Damages (as defined in the Indemnity Escrow Agreement), if any, as provided in Section 7(a) of the Indemnity Escrow Agreement, and (B) Estimated Fees (as defined in the Indemnity Escrow Agreement)) shall cease to be classified as “Indemnity Escrowed Warrant Shares” and shall no longer be used to satisfy any indemnification claim of Parent under Article VIII of the Merger Agreement. As each claim described in clause (ii) of the preceding sentence is resolved, the Indemnity Escrowed Warrant Shares then remaining in the Warrant Escrow Fund and not required to satisfy such resolved claims or any remaining unresolved claims shall cease to be classified as “Indemnity Escrowed Warrant Shares,” subject to any obligation to distribute such Indemnity Escrowed Warrant Shares as requested by the Securityholders’ Representative pursuant to Section 7(c) of the Indemnity Escrow Agreement. In the event the Securityholders’ Representative’s actual fees incurred in resolving all unresolved claims as of the last day of the Indemnity Escrow Period is less than the Estimated Fees, the remaining number of Indemnity Escrowed Warrant Shares shall cease to be classified as “Indemnity Escrowed Warrant Shares” and shall no longer be used to satisfy any indemnification claim of Parent under Article VIII of the Merger Agreement.

     (d) Fund Deficiency. Distributions shall be made from the Indemnity Escrowed Warrant Shares to satisfy any Fund Deficiency as provided in Section 7(c) of the Indemnity Escrow Agreement.

     7. Securityholders’ Representative.

     (a) Removal. The Securityholders’ Representative may be changed in accordance with the terms of Section 8.7 of the Merger Agreement and the Securityholders’ Representative Fund Escrow Agreement. A Majority of the Securityholders shall notify the Warrant Escrow Agent and Parent in writing of any such change and the Warrant Escrow Agent and Parent shall be entitled to rely upon such notice without further inquiry.

     (b) Fees. No bond shall be required of the Securityholders’ Representative. As more fully provided in the Indemnity Escrow Agreement and the Securityholders’ Representative Fund Escrow Agreement, the Securityholders’ Representative shall be entitled to

7

receive a fee of $250.00 per hour for time spent fulfilling the Securityholders’ Representative Obligations, with such fees to be paid out of the Indemnity Escrow Fund and the Indemnity Escrowed Warrant Shares as provided in the Indemnity Escrow Agreement.

     (c) Reliance. Notices or communications to or from the Securityholders’ Representative shall constitute notice to or from each of the Securityholders. A decision, act, consent or instruction of the Securityholders’ Representative shall constitute a decision of all Securityholders and shall be final, binding and conclusive upon each of such Securityholders, and the Warrant Escrow Agent and Parent may rely upon any such decision, act, consent or instruction of the Securityholders’ Representative as being the decision, act, consent or instruction of each and every such Securityholder. The Warrant Escrow Agent and Parent are hereby relieved from any liability to any person for any acts done by them in accordance with such decision, act, consent or instruction of the Securityholders’ Representative. The Securityholders’ Representative shall not be liable to the Securityholders for any act done or omitted hereunder as the Securityholders’ Representative except as provided in Section 8.7 of the Merger Agreement. Notwithstanding the foregoing, after the Indemnity Escrow Termination Date, the Securityholders’ Representative shall be entitled to have his fees for time spent by him fulfilling his duties under this Agreement paid out of the Warrant Escrow Fund before any distribution is made pursuant to Section 5(c)(i).

     8. Warrant Escrow Agent.

     (a) Duties. The Warrant Escrow Agent shall hold and safeguard the Warrant Escrow Fund during the Warrant Escrow Period, and shall hold and dispose of the Warrant Escrow Fund only in accordance with the terms of this Agreement and with at least the same degree of care that it exercises with respect to its own similar property. The Warrant Escrow Agent: (i) shall be obligated only for the performance of such duties as are specifically set forth in this Agreement; (ii) shall not be responsible for any of the agreements referred to or described herein (including the Merger Agreement or any of the exhibits thereto), or for determining or compelling compliance therewith, and shall not otherwise be bound thereby, except where such other agreement is referred to in this Agreement either (A) explicitly or (B) implicitly by use of a capitalized term not defined herein but defined therein; (iii) shall not be obligated to take any legal or other action hereunder which might in its reasonable judgment involve material expense or liability unless it shall have been furnished with indemnity reasonably acceptable to it; (iv) may rely on and shall be protected in acting or refraining from acting upon any written notice, instruction, instrument, statement, request or document furnished to it hereunder and reasonably believed by it to be genuine and to have been signed or presented by the proper person, and shall have no responsibility for determining the accuracy thereof; and (v) may consult counsel satisfactory to it, including in-house counsel, in respect of any action taken, suffered or omitted by it hereunder. Without limiting the generality of clause (iv) above, the Warrant Escrow Agent shall be entitled to rely conclusively upon a Joint Certificate with respect to the Merger Consideration to be paid to the holder of an exercised Company Warrant named in such Joint Certificate pursuant to such instrument without any duty to verify or recalculate the same.

     (b) Compliance with Orders. The Warrant Escrow Agent is hereby expressly authorized to comply with and obey orders, judgments or decrees of any court or any written decision of arbitrators. If the Warrant Escrow Agent obeys or complies with any such order, judgment or decree of any court or any written decision of arbitrators, the Warrant Escrow Agent

8

shall not be liable to any of the parties hereto or to any other person by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction.

     (c) Reliance. The Warrant Escrow Agent shall not be liable in any respect on account of the identity, authority or rights of the other parties executing or delivering or purporting to execute or deliver this Agreement or any documents or papers deposited or called for hereunder.

     (d) Indemnification. Neither the Warrant Escrow Agent nor any of its directors, officers or employees shall be liable to anyone for any action taken or omitted to be taken by it or any of its directors, officers or employees hereunder except in the case of gross negligence, bad faith or willful misconduct. In no event shall the Warrant Escrow Agent be liable for indirect, punitive, special or consequential damages or loss whatsoever. Parent and the Securityholders (collectively, the “Escrow Agent Indemnifying Parties”) shall, jointly and severally, indemnify the Warrant Escrow Agent and hold it harmless from and against any fee, loss, liability or expense (including reasonable attorneys’ fees and expenses) (a “Loss”) incurred by the Warrant Escrow Agent arising out of or in connection with the performance of its obligations in accordance with the provisions of this Agreement or with the administration of its duties hereunder, unless such Loss shall arise out of or be caused by the Warrant Escrow Agent’s gross negligence, bad faith or willful misconduct; provided, however, that the Indemnity Escrowed Warrant Shares shall be the exclusive source for the satisfaction by the Securityholders of the indemnification obligation set forth in this Section 8(d); provided, further, that the indemnity agreement contained in this Section 8(d) shall not apply to amounts paid in settlement of any Loss if such settlement is effected without the consent of the Securityholders’ Representative and Parent.

     (e) Contribution. Each of the Escrow Agent Indemnifying Parties shall contribute to the indemnification liability under this Section 8 in such proportion as is appropriate to reflect the relative fault of each individual Escrow Agent Indemnifying Party. In all cases where there is no such basis for allocating contribution for such indemnification liability, one half of the total of such indemnification liability shall be paid out of the Indemnity Escrowed Warrant Shares and one half of the total of such indemnification liability shall be paid by Parent; provided, however, that if insufficient funds are available from the then remaining Indemnity Escrowed Warrant Shares (the “Shortfall”) to pay such half, then Parent shall pay the amount of such Shortfall.

     (f) Resignation; Removal. The Warrant Escrow Agent may (i) be removed by mutual consent of Parent and the Securityholders’ Representative, provided that the Indemnity Escrow Agent and the Securityholders’ Escrow Agent are also so removed, and (ii) resign at any time, in each case, upon giving at least 30 days’ prior written notice to the Warrant Escrow Agent or Parent and the Securityholders’ Representative, as applicable; provided, however, that no such resignation shall become effective until the appointment of a successor escrow agent, which shall be accomplished as follows: Parent and the Securityholders’ Representative shall use their best efforts to mutually agree upon a successor agent within 30 days after the applicable party receives, or parties receive, such notice. If the parties fail to agree upon a successor escrow agent within such time, the Securityholders’ Representative, with the consent of Parent, which shall not be unreasonably withheld, conditioned or delayed, shall have the right to appoint a successor escrow agent. The successor escrow agent selected in the

9

preceding manner shall execute and deliver an instrument accepting such appointment and becoming a party to this Agreement and it shall thereupon be deemed the Warrant Escrow Agent hereunder and it shall without further acts be vested with all the estates, properties, rights, powers, and duties of the predecessor the Warrant Escrow Agent as if originally named as the Warrant Escrow Agent. If no successor escrow agent is named, the Warrant Escrow Agent may apply to a court of competent jurisdiction for the appointment of a successor escrow agent. Thereafter, the predecessor Warrant Escrow Agent shall be discharged from any further duties and liabilities under this Agreement. If the Warrant Escrow Agent is removed pursuant to clause (i) above, Parent and the Securityholders’ Representative shall appoint a successor escrow agent in accordance with the procedure set forth in clause (ii) above, provided that the successor escrow agent appointed is the same as the successor escrow agent appointed under the Indemnity Escrow Agreement and the Securityholders’ Representative Fund Escrow Agreement. The provisions of Section 8(d) shall survive the resignation or removal of the Warrant Escrow Agent or the termination of this Agreement.

     (g) Parent as Warrant Escrow Agent. Notwithstanding anything contained herein to the contrary, if the Company Warrants have been exercised prior to the “Warrant Escrow Agent Termination Date” (such date being the later of (i) the second anniversary of the Closing Date and (ii) the Indemnity Escrow Termination Date, as the same shall have been extended until such date as all unresolved claims on that date shall have been resolved) and upon delivery of 10 days’ advance written notice to the Securityholders’ Representative, Parent, at its election, may cause the Warrant Escrow Agent to be removed replaced by Parent, who thereupon shall act as Warrant Escrow Agent hereunder; provided, however, that the Warrant Escrow Agent in place immediately prior to the Warrant Escrow Agent Termination Date shall not be so removed if the Securityholders’ Representative shall agree to pay or reimburse all of the normal fees and expenses of the Warrant Escrow Agent so in place that are incurred on or after the Warrant Escrow Agent Termination Date, such reimbursement obligation to be satisfied solely from the Warrant Escrow Fund. In the event of an election by Parent under this Section 8(g), the provisions of this Section 8 shall no longer apply.

     (h) Distribution of Warrant Escrow Fund. Notwithstanding any term appearing in this Agreement to the contrary, in no instance shall the Warrant Escrow Agent be required or obligated to distribute any of the Warrant Escrow Fund (or take other action that may be called for hereunder to be taken by the Warrant Escrow Agent) sooner than two Business Days after (i) it has received the applicable documents required under this Agreement or (ii) passage of the applicable time period (or both, as applicable under the terms of this Agreement), as the case may be.

     (i) Disputes. Should any dispute arise with respect to the delivery, ownership, right of possession, and/or disposition of the Warrant Escrow Fund, or should any claim be made upon the Warrant Escrow Agent or the Warrant Escrow Fund by a third party, the Warrant Escrow Agent upon receipt of notice of such dispute or claim is authorized and shall be entitled (at its sole option and election) to retain in its possession without liability to anyone, the portion of the Warrant Escrow Fund in dispute until such dispute shall have been settled either by the mutual written agreement of the parties involved or by a final order, decree or judgment of a court in the United States of America, the time for perfection of an appeal of such order, decree or judgment having expired. The Warrant Escrow Agent may, but shall be under no duty whatsoever to, institute or defend any legal proceedings which relate to the Warrant Escrow Fund.

10

     (j) Transfer Agent. The Warrant Escrow Agent shall deliver to Mellon Investor Services (the “Transfer Agent”) the original stock certificates representing Escrowed Warrant Shares, together with appropriate instructions, whenever the Warrant Escrow Agent is to disburse Escrowed Warrant Shares, whether in payment of a claim or to the Securityholders, under the terms hereof. The Warrant Escrow Agent shall not be liable for the actions or inaction of the Transfer Agent provided the Warrant Escrow Agent has given the Transfer Agent instructions which conform to the terms hereof. Parent shall cause the Transfer Agent to issue to the Warrant Escrow Agent stock certificates representing the Escrowed Warrant Shares remaining in the Warrant Escrow Fund upon a distribution of the Escrowed Warrant Shares and to issue stock certificates in the name of the Securityholders, as instructed by the Securityholders’ Representative.

     (k) Periodic Statements. Within ten days following the end of each month, the Warrant Escrow Agent shall provide to Parent and the Securityholders’ Representative [monthly][quarterly] statements identifying transactions, transfers or holdings of the Warrant Escrow Fund. Each [monthly][quarterly] statement shall be deemed to be correct and final upon receipt thereof by Parent and the Securityholders’ Representative unless either one notifies the Warrant Escrow Agent and the other party in writing to the contrary within 30 days of the date of such statement.

     (l) Fees and Expenses. Parent and the Securityholders shall pay or reimburse the Warrant Escrow Agent for its normal services hereunder. Such fees shall be shared equally by Parent and the Securityholders. The Warrant Escrow Agent shall satisfy the Securityholders’ portion of such reimbursement obligation solely from the Warrant Escrow Fund.

     9. Miscellaneous.

     (a) Amendments and Waivers. Any term of this Agreement may be amended or waived only with the written consent of Parent, the Securityholders’ Representative and the Warrant Escrow Agent. Any amendment or waiver effected in accordance with this Section 9(a) shall be binding upon the parties and their respective successors and assigns.

     (b) Successors and Assigns. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and assigns of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. If the Warrant Escrow Agent consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Warrant Escrow Agent.

The parties to this Agreement agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any court of the State of Delaware or of the United States, in the State of Delaware, in either case sitting in Wilmington, Delaware, this being in addition to any other remedy to which they are entitled under this Agreement.

11

     (d) Governing Law; Jurisdiction; Jury Trial. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to the laws that might otherwise govern under applicable principles of conflicts of law.

EXHIBIT G

SECURITYHOLDERS’ REPRESENTATIVE FUND ESCROW AGREEMENT

     SECURITYHOLDERS’ REPRESENTATIVE FUND ESCROW AGREEMENT, dated as of _____________, 2005 (this “Agreement”), by and among IVANHOE ENERGY INC., a Yukon corporation (“Parent”), ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇ (the “Securityholders’ Representative”) and MELLON INVESTOR SERVICES, a _____________, as escrow agent (the “Securityholders’ Escrow Agent”).

RECITALS

               A. Parent, Ivanhoe Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub”), and Ensyn Group, Inc., a Delaware corporation (the “Company”), have entered into an Agreement and Plan of Merger, dated as of December 11, 2004 (the “Merger Agreement”), pursuant to which Parent will acquire the Company through the merger (the “Merger”) of Merger Sub with and into the Company with the Company as the surviving corporation.

               B. Immediately prior to the Merger, it is contemplated under the Merger Agreement that Parent and certain Canadian stockholders of the Company will consummate a transaction whereby such stockholders will exchange their shares for the consideration they would have received in respect of those shares pursuant to the Merger had they not sold their shares to Parent immediately prior to the Merger (the “Canadian Transaction”).

               C. The Merger Agreement and the Canadian Exchange Agreement contemplate that the Securityholders’ Representative may draw funds from the Securityholders’ Representative Fund for the payment of any out-of-pocket fees and expenses, including reasonable legal and accounting fees and expenses (the “Securityholders’ Representative Expenses”), associated with the Securityholders’ Representative’s execution of the duties and obligations as such representative under the terms of this Agreement, the Merger Agreement (including any letters of transmittal contemplated thereby), the Canadian Exchange Agreement, the Indemnity Escrow Agreement and the Warrant Escrow Agreement (the “Securityholders’ Representative Obligations”).

               D. Pursuant to the Merger Agreement and the Canadian Transaction, the Securityholders, as part of the consideration to be paid for their shares of Company Common Stock, will receive a cash payment, a portion of which is to be deposited into the Securityholders’ Representative Fund provided for hereby.

               E. The parties desire to establish the terms and conditions pursuant to which the Securityholders’ Representative Fund will be established and maintained.

               Accordingly, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties to this Agreement agree as follows:

     1. Defined Terms. Capitalized terms used in this Agreement and not otherwise defined herein shall have the respective meanings given to them in the Merger Agreement.

     2. Consent of Securityholders and Securityholders’ Representative; Appointment of Securityholders’ Escrow Agent. By virtue of the approval of the Merger Agreement by the stockholders of the Company, and pursuant to the Canadian Exchange Agreement, the Securityholders have, without any further act of any Securityholder, consented to (i) the establishment of the Securityholders’ Representative Fund to provide the means for paying the Securityholders’ Representative Expenses, (ii) the appointment of the Securityholders’ Representative as their representative for purposes of this Agreement and as attorney-in-fact and agent for and on behalf of each Securityholder with respect to the subject matter of this Agreement, (iii) the taking by the Securityholders’ Representative of any and all actions and the making of any and all decisions required or permitted to be taken or made by them under this Agreement (including, without limitation, authorizing payment of the Securityholders’ Representative Expenses) and (iv) all of the other provisions set forth in this Agreement. The Securityholders’ Representative hereby agrees to act as the Securityholders’ representative in accordance with, and agrees to be bound by, the applicable terms of this Agreement and the Merger Agreement. The Securityholders’ Escrow Agent hereby accepts appointment as the Securityholders’ escrow agent and agrees to accept delivery of and hold the Securityholders’ Representative Fund in escrow subject to the terms and conditions of this Agreement and the Merger Agreement.

     3. Securityholders’ Escrow.

               (a) Securityholders’ Representative Fund. Pursuant to Section 2.2(f) of the Merger Agreement, at the Closing Parent shall deposit with the Securityholders’ Escrow Agent an amount in cash equal to $1,000,000 (together with any income earned thereon, the “Securityholders’ Representative Fund”).

               (b) Investment. The Securityholders’ Escrow Agent shall invest and reinvest the Securityholders’ Representative Fund in money market funds that invest primarily in short-term U.S. Treasury securities, obligations of or guaranteed by the United States of America or any agency thereof, certificates of deposit or bankers acceptances issued by any national or state chartered bank having total assets of at least $500,000,000 with a maturity not later than one year from the date of investment, or such other investments as may be specified from time to time to the Securityholders’ Escrow Agent by the written instructions of the Securityholders’ Representative. In no event shall the Securityholders’ Escrow Agent be liable for the selection of investments or for investment losses incurred thereon. In no event shall the Securityholders’ Representative be liable for the election of investments or for investment losses incurred thereon, except as provided in Section 8.7 of the Merger Agreement.

     4. Pro Rata Portion. Each Securityholder’s proportionate interest in the Securityholders’ Representative Fund shall be equal to such Securityholder’s Pro Rata Portion. Immediately prior to any distribution pursuant to Section 6, the Securityholders’ Escrow Agent shall request and Parent shall provide to the Securityholders’ Escrow Agent a schedule setting forth, as of the date of such request, the name of each Securityholder and such Securityholder’s Pro Rata Portion; provided, however, that such schedule shall be approved by the Securityholders’ Representative (which approval shall not be unreasonably withheld or delayed) prior to Parent delivering such schedule to the Securityholders’ Escrow Agent. The Securityholders’ Escrow Agent and Parent (after approval of such schedule by the

2

Securityholders’ Representative) shall be entitled to rely conclusively on the information set forth in the schedule of the Securityholders’ Pro Rata Portions provided to the Securityholders’ Escrow Agent.

     5. Payment of Securityholders’ Representative Expenses.

               (a) The Securityholders’ Representative may submit any Securityholders’ Representative Expenses associated with the Securityholders’ Representative Obligations (a “Submitted Expense”) for payment out of the Securityholders’ Representative Fund by delivering to the Securityholders’ Escrow Agent (with a copy to the designated representative of Credit Suisse First Boston Management Corporation, ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇ and Parent) at any time on or before 5:00 p.m. (EST) on the last day of the Securityholders’ Escrow Period, a certificate signed by the Securityholders’ Representative (a “Certificate”) that, with respect to such expense, (i) sets forth the amount of the Submitted Expense, together with an invoice or similar form substantiating such amount, (ii) contains instructions for payment and (iii) describes in reasonable detail the Securityholders’ Representative Obligations that gave rise to the Submitted Expense. Upon timely receipt of a Certificate requesting payment of a Submitted Expense, the Securityholders’ Escrow Agent shall promptly pay such Submitted Expense in accordance with the payment instructions set forth in the Certificate out of the Securityholders’ Representative Fund.

               (b) If at any time the amount in the Securityholders’ Representative Fund is not sufficient to cover payment of a Submitted Expense, the Securityholders’ Representative shall have the right to submit such expense for payment out of the Indemnity Escrow Fund and the Warrant Escrow Fund as provided for under the Indemnity Escrow Agreement and Warrant Escrow Agreement, respectively.

     6. Expiration and Release of Securityholders’ Representative Fund. (a) The Securityholders’ Representative Fund shall remain in existence from the Closing Date until the earlier of: (a) the date on which the balance of the Securityholders’ Representative Fund falls below $1,000 or (b) the date on which both the Warrant Escrow Fund and the Indemnity Escrow Fund are terminated (or with respect to the Warrant Escrow Fund, the date on which Parent becomes Warrant Escrow Agent) pursuant to the Warrant Escrow Agreement and Indemnity Escrow Agreement, respectively (the “Securityholders’ Escrow Period”). Promptly upon expiration of the Securityholders’ Escrow Period, the Securityholders’ Representative shall deliver a certificate signed by it to the Securityholders’ Escrow Agent notifying it of such expiration. Upon the expiration of the Securityholders’ Escrow Period, the Securityholders’ Representative Fund shall terminate, and any amounts remaining in the Securityholders’ Representative Fund shall be delivered to the Securityholders in proportion to each Securityholder’s Pro Rata Portion (calculated pursuant to Section 4 hereof) and to the Warrant Escrow Agent, as applicable; provided, however, that if the Securityholders’ Representative Fund expires due to the passage of time, (i) an amount equal to the full amount of each Submitted Expense specified in any Certificate containing a demand for payment delivered to the Securityholders’ Escrow Agent on or before the end of the last day of the Securityholders’ Escrow Period that remains unpaid as of the last day of the Securityholders’ Escrow Period shall remain in the Securityholders’ Representative Fund (and the Securityholders’ Representative Fund shall remain in existence) until such expenses have been paid, and (ii) any distribution shall

3

be subject to, and shall not be made prior to, the payment of such Submitted Expenses.

               (a) Following the termination of the Securityholders’ Escrow Period, this Agreement shall terminate, except that Sections 8(d) and (e) shall continue to be effective until such time as the Warrant Escrow Agreement is terminated.

     7. Taxes. For tax reporting purposes, interest or other income earned from the investment of the Securityholders’ Representative Fund or any portion thereof that is distributed by the Securityholders’ Escrow Agent to any Person pursuant to the terms of this Agreement shall be reported as allocated to such Person when paid to such Person. Each Securityholder shall be responsible for his, her or its Pro Rata Portion of (i) all Taxes resulting from any interest or other income earned on the Securityholders’ Representative Fund and (ii) all Taxes resulting from any distributions of the Securityholders’ Representative Fund to such Securityholder.

     8. Securityholders’ Representative.

               (a) Removal. The Securityholders’ Representative may be changed in accordance with the terms of Section 8.7 of the Merger Agreement. A Majority of the Securityholders shall notify the Securityholders’ Escrow Agent and Parent in writing of any such change and the Securityholders’ Escrow Agent and Parent shall be entitled to rely upon such notice without further inquiry. The provisions of Section 8(d) shall survive the removal or resignation of any Securityholders’ Representative.

               (b) Fees. No bond shall be required of the Securityholders’ Representative. As more fully provided in the Indemnity Escrow Agreement, the Securityholders’ Representative shall be entitled to receive a fee of $250.00 per hour for time spent fulfilling the Securityholders’ Representative Obligations, with such fees to be paid out of the Indemnity Escrow Fund and Indemnity Escrowed Warrant Shares.

               (c) Reliance. Notices or communications to or from the Securityholders’ Representative shall constitute notice to or from each of the Securityholders. A decision, act, consent or instruction of the Securityholders’ Representative shall constitute a decision of all Securityholders and shall be final, binding and conclusive upon each of such Securityholders, and the Securityholders’ Escrow Agent and Parent may rely upon any such decision, act, consent or instruction of the Securityholders’ Representative as being the decision, act, consent or instruction of each and every such Securityholder. The Securityholders’ Escrow Agent and Parent are hereby relieved from any liability to any Person for any acts done by them in accordance with such decision, act, consent or instruction of the Securityholders’ Representative. The Securityholders’ Representative shall not be liable to the Securityholders for any act done or omitted hereunder as the Securityholders’ Representative except as provided in Section 8.7 of the Merger Agreement.

               (d) Indemnification. Each Securityholder shall severally indemnify the Securityholders’ Representative and hold him harmless from and against any fee, loss, liability or expense (including reasonable attorneys’ fees and expenses) (a “Loss”) incurred by the Securityholders’ Representative arising out of or in connection with the acceptance or performance of his obligations under this Agreement, the Indemnity Escrow Agreement, the

4

Warrant Escrow Agreement or the Merger Agreement. The Securityholders’ Representative shall be entitled to be reimbursed for any such Loss first out of any funds otherwise distributable to the Securityholders, including amounts distributable out of the Securityholders’ Escrow Fund pursuant to Section 6, amounts distributable out of the Indemnity Escrow Fund or release of the Indemnity Escrowed Warrant Shares and amounts distributable pursuant to Section 5(c)(i) of the Warrant Escrow Agreement, and then by the Securityholders pursuant to Section 8(e) of this Agreement.

     (e) Right of Contribution. If at any time amounts in the Securityholders’ Representative Fund and the Indemnity Escrow Fund and the Indemnity Escrowed Warrant Shares are insufficient to cover payment of a Submitted Expense or a Loss, then the Securityholders’ Representative shall have the right to seek contribution from any or all Securityholders of such Submitted Expense or Loss (the “Contribution Amount”). If such Securityholder does not pay his, her or its Contribution Amount within 20 Business Days following receipt of a written request for the Contribution Amount from the Securityholders’ Representative, any unpaid amount shall bear default interest from and including the due date to but excluding the date of payment at a rate per annum equal to the prime rate as published in The Wall Street Journal, Central Edition in effect from time to time. Such interest shall be payable at the same time as the payment to which it relates and shall be calculated daily on the basis of a year of 365 days and the actual number of days elapsed. The Securityholders’ Representative shall be entitled to take all actions reasonably necessary to collect any Contribution Amount from each Securityholder.

     9. Securityholders’ Escrow Agent.

     (a) Duties. The Securityholders’ Escrow Agent shall hold and safeguard the Securityholders’ Representative Fund during the Securityholders’ Escrow Period, and shall hold and dispose of the Securityholders’ Representative Fund only in accordance with the terms of this Agreement and with at least the same degree of care that it exercises with respect to its own similar property. The Securityholders’ Escrow Agent: (i) shall be obligated only for the performance of such duties as are specifically set forth in this Agreement; (ii) shall not be responsible for any of the agreements referred to or described herein (including the Merger Agreement or any of the exhibits thereto), or for determining or compelling compliance therewith, and shall not otherwise be bound thereby, except where such other agreement is referred to in this Agreement either (A) explicitly or (B) implicitly by use of a capitalized term not defined herein but defined therein; (iii) shall not be obligated to take any legal or other action hereunder which might in its reasonable judgment involve material expense or liability unless it shall have been furnished with indemnity reasonably acceptable to it; (iv) may rely on and shall be protected in acting or refraining from acting upon any written notice, instruction, instrument, statement, request or document furnished to it hereunder and reasonably believed by it to be genuine and to have been signed or presented by the proper person, and shall have no responsibility for determining the accuracy thereof; and (v) may consult counsel satisfactory to it, including in-house counsel, in respect of any action taken, suffered or omitted by it hereunder. Without limiting the generality of clause (iv) above, the Securityholders’ Escrow Agent shall be entitled to rely conclusively upon a Certificate for the amount to be paid to the Person named in such Certificate without any duty to verify or recalculate same.

5

     (b) Compliance with Orders. The Securityholders’ Escrow Agent is hereby expressly authorized to comply with and obey orders, judgments or decrees of any court or any written decision of arbitrators. If the Securityholders’ Escrow Agent obeys or complies with any such order, judgment or decree of any court or any written decision of arbitrators, the Securityholders’ Escrow Agent shall not be liable to any of the parties hereto or to any other person by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction.

     (c) Reliance. The Securityholders’ Escrow Agent shall not be liable in any respect on account of the identity, authority or rights of the other parties executing or delivering or purporting to execute or deliver this Agreement or any documents or papers deposited or called for hereunder.

     (d) Indemnification. Neither the Securityholders’ Escrow Agent nor any of its directors, officers or employees shall be liable to anyone for any action taken or omitted to be taken by it or any of its directors, officers or employees hereunder except in the case of gross negligence, bad faith or willful misconduct. In no event shall the Securityholders’ Escrow Agent be liable for indirect, punitive, special or consequential damages or loss whatsoever. Parent and the Securityholders (collectively, the “Escrow Agent Indemnifying Parties”) shall, jointly and severally, indemnify the Securityholders’ Escrow Agent and hold it harmless from and against any Loss incurred by the Securityholders’ Escrow Agent arising out of or in connection with the performance of its obligations in accordance with the provisions of this Agreement or with the administration of its duties hereunder, unless such Loss shall arise out of or be caused by the Securityholders’ Escrow Agent’s gross negligence, bad faith or willful misconduct; provided, however, that the Securityholders’ Representative Fund shall be the exclusive source for the satisfaction by the Securityholders of the indemnity obligations contained in this Section 9(d); provided, further, that the indemnity agreement contained in this Section 9(d) shall not apply to amounts paid in settlement of any Loss if such settlement is effected without the consent of the Securityholders’ Representative.

     (e) Contribution. Each of the Escrow Agent Indemnifying Parties shall contribute to the indemnification liability under this Section 9 in such proportion as is appropriate to reflect the relative fault of each individual Escrow Agent Indemnifying Party. In all cases where there is no such basis for allocating contribution for such indemnification liability, one half of the total of such indemnification liability shall be paid by Parent and one half of the total of such indemnification liability shall be paid out of the Securityholders’ Representative Fund; provided, however, that if insufficient funds are available in the Securityholders’ Representative Fund (the “Shortfall”), then Parent shall pay the amount of such Shortfall.

     (f) Resignation; Removal. The Securityholders’ Escrow Agent may (i) be removed by mutual consent of Parent and the Securityholders’ Representative, provided that the Indemnity Escrow Agent and Warrant Escrow Agent are also so removed, and (ii) resign at any time, in each case, upon giving at least 30 days’ prior written notice to the Securityholders’ Representative and Parent; provided, however, that no such resignation shall become effective until the appointment of a successor escrow agent, which shall be accomplished as follows:

6

     Parent and the Securityholders’ Representative shall use their best efforts to mutually agree upon a successor agent within 30 days after the applicable party receives, or parties receive, such notice. If the parties fail to agree upon a successor escrow agent within such time, the Securityholders’ Representative, with the consent of Parent, which shall not be unreasonably withheld, conditioned or delayed, shall have the right to appoint a successor escrow agent. The successor escrow agent selected in the preceding manner shall execute and deliver an instrument accepting such appointment and becoming a party to this Agreement and it shall thereupon be deemed the Securityholders’ Escrow Agent hereunder and it shall without further acts be vested with all the estates, properties, rights, powers, and duties of the predecessor the Securityholders’ Escrow Agent as if originally named as the Securityholders’ Escrow Agent. If no successor escrow agent is named, the Securityholders’ Escrow Agent may apply to a court of competent jurisdiction for the appointment of a successor escrow agent. Thereafter, the predecessor Securityholders’ Escrow Agent shall be discharged from any further duties and liabilities under this Agreement. If the Securityholders’ Escrow Agent is removed pursuant to clause (i) above, Parent and the Securityholders’ Representative shall appoint a successor escrow agent in accordance with the procedure set forth in this Section 9(f), provided that the successor escrow agent is the same as the successor escrow agent appointed under the Indemnity Escrow Agreement and the Warrant Escrow Agreement. The provisions of Section 9(d) shall survive the resignation or removal of the Securityholders’ Escrow Agent or the termination of this Agreement. Nothing in this Section 9(f) shall affect Parent’s right under Section 8(g) of the Warrant Escrow Agreement.

     (g) Distribution of Securityholders’ Representative Fund. Notwithstanding any term appearing in this Agreement to the contrary, in no instance shall the Securityholders’ Escrow Agent be required or obligated to distribute any of the Securityholders’ Representative Fund (or take other action that may be called for hereunder to be taken by the Securityholders’ Escrow Agent) sooner than two Business Days after (i) it has received the applicable documents required under this Agreement or (ii) passage of the applicable time period (or both, as applicable under the terms of this Agreement), as the case may be.

     (h) Disputes. Should any dispute arise with respect to the delivery, ownership, right of possession, and/or disposition of the Securityholders’ Representative Fund, or should any claim be made upon the Securityholders’ Escrow Agent or the Securityholders’ Representative Fund by a third party, the Securityholders’ Escrow Agent upon receipt of notice of such dispute or claim is authorized and shall be entitled (at its sole option and election) to retain in its possession without liability to anyone, the portion of the Securityholders’ Representative Fund in dispute until such dispute shall have been settled either by the mutual written agreement of the parties involved or by a final order, decree or judgment of a court in the United States of America, the time for perfection of an appeal of such order, decree or judgment having expired. The Securityholders’ Escrow Agent may, but shall be under no duty whatsoever to, institute or defend any legal proceedings which relate to the Securityholders’ Representative Fund.

     (i) Fees and Expenses. Parent and the Securityholders shall pay or reimburse the Securityholders’ Escrow Agent for its normal services hereunder. Such fees shall be shared equally by Parent and the Securityholders. The Securityholders’ Escrow Agent shall satisfy the

7

Securityholders’ portion of such reimbursement obligation from the Securityholders’ Representative Fund.

     (j) Periodic Statements. Within ten days following the end of each month, the Securityholders’ Escrow Agent shall provide to the Securityholders’ Representative [monthly][quarterly] statements identifying transactions, transfers or holdings of the Securityholders’ Representative Fund. Each [monthly][quarterly] statement shall be deemed to be correct and final upon receipt thereof by the Securityholders’ Representative unless the Securityholders’ Representative notifies the Securityholders’ Escrow Agent in writing to the contrary within 30 days of the date of such statement.

     10. Miscellaneous.

     (a) Amendments and Waivers. Any term of this Agreement may be amended or waived only with the written consent of Parent, the Securityholders’ Representative and the Securityholders’ Escrow Agent. Any amendment or waiver effected in accordance with this Section 10(a) shall be binding upon the parties and their respective successors and assigns.

     (b) Successors and Assigns. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors and assigns of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. If the Securityholders’ Escrow Agent consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Securityholders’ Escrow Agent.

     (c) Governing Law; Jurisdiction; Jury Trial. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to the laws that might otherwise govern under applicable principles of conflicts of law. The parties to this Agreement (i) irrevocably submit to the personal jurisdiction of the state or federal courts of the United States of America located in Wilmington, Delaware and (ii) waive any claim of improper venue or any claim that those courts are in an inconvenient forum. The parties agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 10(g) or in such other manner as may be permitted by law, shall be valid and sufficient service thereof. Each party to this Agreement irrevocably waives the right to trial by jury in connection with any matter arising out of this Agreement.

     (d) Specific Performance. The parties to this Agreement agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any court of the State of Delaware or of the United States, in the State of Delaware, in either case sitting in Wilmington, Delaware, this being in addition to any other remedy to which they are entitled under this Agreement.

8

     (e) Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. The exchange of copies of this Agreement and of signature pages by facsimile transmission shall constitute effective execution and delivery of this Agreement as to the parties and may be used in lieu of the original Agreement for all purposes.

Ladies and Gentlemen:

     I have been advised that I may be deemed to be an “Affiliate” of Ensyn Group, Inc., a Delaware corporation (the “Company”), as that term is defined for purposes of paragraphs (c) and (d) of Rule 145 of the rules and regulations (the “Rules and Regulations”) of the United States Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “Securities Act”). Neither my entering into this letter agreement nor anything contained in this letter agreement, shall be deemed an admission on my part that I am such an “Affiliate.”

     Under the terms of the Agreement and Plan of Merger, dated as of December      , 2004 (the “Merger Agreement”), by and among Ivanhoe Energy Inc., a Delaware corporation (“Parent”), Ivanhoe Merger Sub, Inc., a Delaware corporation (“Merger Sub”), and the Company. Merger Sub plans to merge with and into the Company (the “Merger”). As a result of the Merger, I may receive common shares, par value $.001 per share, of Parent (the “Parent Common Stock”) in exchange for my shares of common stock, par value $.001 per share, of the Company.

     I represent and warrant to Parent and Merger Sub that in such event:

     A. I shall not make any sale, transfer or other disposition of Parent Common Stock in violation of the Securities Act or the Rules and Regulations.

     B. I have carefully read this letter agreement and the Merger Agreement and discussed its requirements and other applicable limitations upon my ability to sell, transfer or otherwise dispose of Parent Common Stock, to the extent I believed necessary, with my counsel or counsel for the Company.

     C. I have been advised that since at the time the Merger is or was submitted for a vote of the stockholders of the Company, I may be or may have been deemed to have been an Affiliate of the Company and a distribution by me of Parent Common Stock has not been registered under the Securities Act, I may not sell, transfer or otherwise dispose of the Parent Common Stock I receive in the Merger unless such sale, transfer or other disposition (i) has been registered under the Securities Act, (ii) is

F-1

made in conformity with the volume and other limitations of Rule 145 promulgated by the SEC under the Securities Act or (iii) occurs in a transaction which, in the opinion of counsel reasonably acceptable to Parent or as described in a “no-action” or interpretive letter from the staff of the SEC, is otherwise exempt from registration under the Securities Act.

     D. I understand that neither Parent nor Merger Sub is under any obligation to register the sale, transfer or other disposition of Parent Common Stock by me or on my behalf or to take any other action necessary in order to make compliance with an exemption from registration available except as indicated below.

     E. I understand that stop transfer instructions will be given to Parent’s transfer agent with respect to my Parent Common Stock and that there will be placed on my Parent Common Stock certificates, or any substitutions for them, a legend stating in substance:

The shares represented by this certificate were issued in a transaction to which Rule 145 promulgated under the Securities Act of 1933, as amended, applies and may only be transferred in compliance with the requirements of Rule 145 or pursuant to a registration statement under said act or an exemption from such registration.

     F. I also understand that, unless the sale, transfer or other disposition by me of Parent Common Stock has been registered under the Securities Act or is a sale made in conformity with the provisions of Rule 145, Parent reserves the right to put the following legend on the certificates issued to my transferee:

The shares represented by this certificate have not been registered under the Securities Act of 1933, as amended, and were acquired from a person who received such shares in a transaction to which Rule 145 promulgated under the Securities Act of 1933, as amended, applies. The shares have been acquired by the holder not with a view to, or for resale in connection with, any distribution of those shares within the meaning of the Securities Act of 1933, as amended, and may not be sold, transferred or otherwise disposed except in accordance with an exemption from the registration requirements of the Securities Act of 1933, as amended.

     It is understood and agreed that the legends set forth above shall be removed by delivery of substitute certificates without such legends, and/or the issuance of a letter to Parent’s transfer agent removing such stop transfer instructions, and the above restrictions on sale will cease to apply, if (A) one year (or such other period as may be required by Rule 145(d)(2) under the Securities Act or any successor thereto) shall have elapsed from the Closing Date and the provisions of such Rule are then available to

F-2

me; or (B) if two years (or such other period as may be required by Rule 145(d)(3) under the Securities Act or any successor thereto) shall have elapsed from the Closing Date and the provisions of such Rule are then available to me; or (C) I shall have delivered to Parent (i) a copy of a letter from the staff of the SEC, or an opinion of counsel in form and substance reasonably satisfactory to Parent, or other evidence reasonably satisfactory to Parent, to the effect that such legends and/or stop transfer instructions are not required for purposes of the Securities Act or (ii) reasonably satisfactory evidence or representations that the securities represented by such certificates are being or have been transferred in a transaction made in conformity with the provisions of Rule 145 under the Securities Act or pursuant to an effective registration statement under the Securities Act.

     By its acceptance hereof, Parent agrees, for a period of two years after the Effective Time, that it will file on a timely basis all reports required to be filed by it pursuant to Sections 13 or 15(d) of the Securities Exchange Act of 1934, as amended, so that the public information provisions of Rule 144(c) promulgated under the Securities Act are satisfied and the resale provisions of Rule 145(d)(1) and (2) promulgated under the Securities Act are therefore available to me in the event I desire to transfer any Parent Common Stock issued to me in the Merger.

     It is understood and agreed that this agreement shall terminate and be of no further force and effect if the Merger Agreement is terminated in accordance with its terms.
