1.3	Tax Treatment.

The Company and the Purchasers agree that the Notes and the Warrants are being issued together as an “investment unit” within the meaning of Section 1273(c)(2) of the Internal Revenue Code. For the purpose of allocating the issue price of the “investment unit” to the Notes and the Warrants, the Company and the Purchasers agree that the aggregate fair market value of the Notes is $73,874,768.79 and the aggregate fair market value of the Warrants is $2,685,231.21, in each case, on the date hereof. The Company and the Purchasers agree that the foregoing allocation will be used to determine the issue price of the “investment unit” for purposes of Section 1273(c)(2) of the Internal Revenue Code and Treasury Regulations Section 1.1273-2(h)(2), and except as otherwise required by applicable Law, to use the foregoing allocation for all applicable Tax purposes with respect to this transaction. The Company and the Purchasers agree (i) that the Notes are debt for U.S. federal income tax purposes, (ii) that the Notes issued to each Purchaser constitute a single debt instrument for purposes of Sections 1271 through 1275 of the Internal Revenue Code and the Treasury Regulations thereunder (pursuant to Treasury Regulations Section 1.1275-2(c)), that such debt instrument is issued with original issue discount (“OID”), and that such debt instrument is described in Treasury Regulations Section 1.1272-1(c)(2) and therefore is governed by the rules set out in Treasury Regulations Section 1.1272-1(c), including Section 1.1272-1(c)(5), and is not governed by the rules set out in Treasury Regulations Section 1.1275-4, (iii) that any calculation by the Company regarding the amount of OID for any accrual period on the Notes shall be as set forth by the Company in a written statement that shall be prepared by the Company consistent herewith within forty-five days of the Closing and will be available to each Purchaser upon request and (iv) to adhere to this Agreement for U.S. federal income tax purposes and not to take any action or file any Tax Return, report or declaration inconsistent herewith (including, with respect to the amount of OID on the Notes, as determined in accordance with the preceding clause (iii)).

(iv) all fees and expenses (including fees and expenses of counsel) in connection with the approval of the Notes, the Warrants and the Warrant Shares by DTC for “book-entry” transfer;

(v) each Purchaser’s expenses (including the fees and expenses of counsel) relating to any amendment to, or modification of, or any waiver or consent or preservation of rights under, this Agreement or any of the other Documents;

(vi) all costs, expenses, fees and taxes incident to and in connection with the issuance and delivery of the Notes, including, without limitation, the fees and expenses of the Trustee and the fees and expenses of the Warrant Agent; and

(vii) all other expenses, including without limitation counsel’s fees, accountants’ fees incurred by the Company in connection with the transactions contemplated by this Agreement or any of the other Documents.

1.5	Registration of Securities.

The Company shall cause to be kept (a) at the offices of the Registrar (as defined in the Indenture), a register for the registration and transfer of the Notes (the “Notes Register”), (b) by

the Warrant Agent, a register for the registration and transfer of the Warrants (the “Warrant Register”) in accordance with the terms of the Warrant Agreement and (c) at the offices of the Transfer Agent, a register for the registration and transfer of the Warrant Shares (the “Common Stock Register”). The names and addresses of the Holders of Notes, each transfer of Notes, and the names and addresses of the transferees of the Notes, shall be registered in the Notes Register.

1.6	Delivery Expenses.

If a Holder surrenders any Security to the Company for any reason, the Company agrees to pay the cost of delivering from or to such ▇▇▇▇▇▇’s home office or from or to the office of such ▇▇▇▇▇▇’s designee from the Company, insured to such ▇▇▇▇▇▇’s satisfaction, the surrendered Security and each Security issued in substitution, replacement or exchange for the surrendered Security.

1.7	Issue Taxes.

The Company agrees to pay all documentary stamp taxes and other governmental charges (other than taxes in the nature of income, franchise, property, estate, inheritance, gift or similar taxes) and governmental fees in connection with the issuance or delivery by the Company to each Holder of the Securities and the execution and delivery of the other Documents and any modification of any of such Securities or other Documents, and will hold such Holder harmless without limitation as to time against any and all liabilities with respect to all such taxes and fees. The obligations of the Company under this Section 1.7 are in addition to any other obligations of the Company contained elsewhere in this Agreement and shall survive the payment or prepayment of the Notes, at maturity, upon redemption or otherwise, the exercise of the Warrants and the termination of this Agreement or any of the other Documents.

1.8	Lost, Etc. Securities.

If a mutilated Security is surrendered to the Company or if the Holder of a Security claims and submits an affidavit or other evidence, satisfactory to the Company, to the effect that the Security has been lost, destroyed or wrongfully taken, the Company shall issue a replacement Security if the customary requirements relating to replacement securities are reasonably satisfied. If required by the Company, such Holder must provide an indemnity bond, or other form of indemnity, sufficient in the judgment of the Company to protect the Company from any loss which it may suffer if a Security is replaced. If any Purchaser or any other institutional Holder (or nominee thereof) is the owner of any such lost, stolen or destroyed Security, then the affidavit of an authorized officer of such owner, setting forth the fact of loss, theft or destruction and of its ownership of the Security at the time of such loss, theft or destruction shall be accepted as satisfactory evidence thereof, and no further indemnity shall be required as a condition to the execution and delivery of a new Security other than the unsecured written agreement of such owner reasonably satisfactory to the Company, to indemnify the Company or at the option of the Purchaser, an indemnity bond in the amount of the Security remaining outstanding. Every replacement Security shall be a valid and binding obligation of the Company.

1.9	Further Actions.

During the period from the date hereof to the Closing Date, the Company shall (i) take all actions necessary or appropriate to cause its representations and warranties contained in Section 3.3 to be true and correct as of the Closing Date (unless stated to refer to another date), both before and after giving effect to the transactions contemplated by this Agreement or any of the other Documents, as if made on and as of such date, and (ii) take, or cause to be taken, all action, and do, or cause to be done, all things necessary, proper or advisable under applicable Law and regulations to consummate and make effective the transactions contemplated by this Agreement or any of the other Documents, including, without limitation, obtaining all consents and approvals of all Persons and removing all injunctive or other impediments or delays, legal or otherwise, which are necessary to the consummation of the transactions contemplated by this Agreement or any of the other Documents.

1.10	Other Covenants.

The Company further covenants and agrees:

(a) to not, and will ensure that no affiliate (as defined in Rule 501(b) of the Securities Act) of the Company, nor any other Person acting on its behalf, will sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in the Securities Act) that would be integrated with the sale of the Securities in a manner that would require the registration under the Securities Act of the sale to the Purchasers of the Securities;

(b) for so long as any of the Securities remain outstanding and during any period in which the Company is not subject to Section 13 or 15(d) of the Exchange Act, to make available to any beneficial owner of Securities and to any prospective purchaser thereof from such beneficial owner, the information required by Rule 144A(d)(4) under the Securities Act;

(c) to cause the Notes, the Warrants and the Warrant Shares to be eligible for clearance and settlement through DTC and to comply with the representation letter of the Company to DTC relating to the approval of such securities by DTC for “book entry” transfer; and

order suspending the qualification or exemption from qualification of any of the Securities under any such laws, use its commercially reasonable efforts to obtain the withdrawal or lifting of such order at the earliest possible time.

1.11	Election to Be Subject to Beneficial Ownership Limitation Provisions.

(a) Each Purchaser agrees that if it indicates below its signature to this Agreement that it has elected to be subject to the provisions set forth below in Section 1.11(b) (the “Beneficial Ownership Limitation Provisions”) it shall be subject to such limitations as they will appear on any certificate representing the Warrants until such time that the Purchaser has provided the Company with the notice described in the Beneficial Ownership Limitation Provisions or those provisions shall have otherwise terminated in accordance those provisions.

(b) The following Beneficial Ownership Limitation Provisions will apply only to a Purchaser who has made the election described in Section 1.11(a): The holder of this Warrant shall not be entitled to receive shares of Common stock upon exercise of this Warrant to the extent (but only to the extent) that such receipt would cause the holder to become, directly or indirectly, a “beneficial owner” (within the meaning of Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder) of a number of shares of Common Stock that exceeds the Maximum Percentage of the shares of Common Stock outstanding at such time. This limitation on beneficial ownership shall be terminated (i) upon 61 days’ notice to the Company by the holder or (ii) immediately on the date that is 30 days prior to the expiration of the Exercise Period of the Warrants. Any purported delivery of shares of Common Stock upon exercise of this Warrant shall be void and have no effect to the extent (but only to the extent) that such delivery would result in the holder becoming the beneficial owner of more than the Maximum Percentage of the shares of Common Stock outstanding at such time. If any delivery of shares of Common Stock owed to the holder upon exercise of this Warrant is not made, in whole or in part, as a result of this limitation, the Company’s obligation to make such delivery shall not be extinguished and the Company shall deliver such shares of Common Stock as promptly as practicable after the holder gives notice to the Company that such delivery would not result in such limitation being triggered or after these beneficial ownership limitation provisions shall have been terminated by the holder of the Warrants or upon 30 days prior to the expiration of the Exercise Period of the Warrants. For purposes of this Agreement, (i) the term “Maximum Percentage” shall mean initially 5%; provided, that if at any time on or after the date hereof the Holder Group beneficially owns in excess of 5% of the outstanding shares of Common Stock (excluding any shares issuable under this Warrant and any other convertible security including a similar limitation), then the Maximum Percentage shall automatically increase to 10% so long as the Holder Group owns in excess of 5% of the outstanding shares of Common Stock (excluding any shares issuable under this Warrant and any other convertible security including a similar limitation), and (ii) the term “Holder Group” shall mean the holder of this Warrant plus any other Person with which such holder is considered to be part of a group under Section 13 of the Exchange Act or with which such holder otherwise files reports under Section 13 or 16 of the Exchange Act.

3.10	Litigation.

There are no actions, suits, proceedings, claims or disputes pending or, to the knowledge of the Company, threatened or contemplated, at Law, in equity, in arbitration or before any Governmental Authority, by or against the Company or any of its Subsidiaries or against any of their properties or revenues that (a) purport to affect or pertain to this Agreement or any other Document, or (b) except as specifically disclosed in Schedule 3.10, either individually or in the aggregate, if determined adversely, could reasonably be expected to have a Material Adverse Effect.

3.11	Environmental Compliance.

(a) The Company and its respective Subsidiaries conduct in the ordinary course of business a review of the effect of existing Environmental Laws on their business, operations and properties and claims asserted against them alleging potential liability or responsibility for violation of any Environmental Law, and as a result thereof the Company has reasonably concluded that such Environmental Laws and such claims could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

3.12	ERISA Compliance.

(a) Each Plan is in compliance with the applicable provisions of ERISA, the Internal Revenue Code and other federal or state laws, except in instances in which any such non-compliance could not be reasonably expected to have a Material Adverse Effect. Each Pension Plan that is intended to be a qualified plan under Section 401(a) of the Internal Revenue Code has received a favorable determination letter from the IRS to the effect that the form of such Plan is qualified under Section 401(a) of the Internal Revenue Code and the trust related thereto has been determined by the IRS to be exempt from federal income tax under Section 501(a) of the Internal Revenue Code, or has an applicable remedial amendment period that will not have ended before the Closing Date.

become due that are unpaid; (v) neither the Company nor any ERISA Affiliate has engaged in a transaction that could be subject to Section 4069 or Section 4212(c) of ERISA; and (vi) no Pension Plan has been terminated by the plan administrator thereof nor by the PBGC, and no event or circumstance has occurred or exists that could reasonably be expected to cause the PBGC to institute proceedings under Title IV of ERISA to terminate any Pension Plan.

(a) Neither the Company nor any Affiliated Entity is (i) a Person whose name appears on the list of Specially Designated Nationals and Blocked Persons published by the Office of Foreign Assets Control, U.S. Department of Treasury (“OFAC”) (an “OFAC Listed Person”) or (ii) a department, agency or instrumentality of, or is otherwise controlled by or acting on behalf of, directly or indirectly, (x) any OFAC Listed Person or (y) the government of a country subject to comprehensive U.S. economic sanctions administered by OFAC (each OFAC Listed Person and each other entity described in clause (ii), a “Blocked Person”).

(b) No part of the proceeds from the sale of the Securities hereunder constitutes or will constitute funds obtained on behalf of any Blocked Person or will otherwise be used, directly by the Company or indirectly through any Affiliated Entity, in connection with any investment in, or any transactions or dealings with, any Blocked Person.

(c) Except as set forth in Schedule 3.14, to the Company’s knowledge, neither the Company nor any Affiliated Entity (i) is under investigation by any Governmental Authority for, or has been charged with, or convicted of, money laundering, drug trafficking, terrorist-related activities or other money laundering predicate crimes under any applicable Law (collectively, “Anti-Money Laundering Laws”), (ii) has been assessed civil penalties under any Anti-Money Laundering Laws or (iii) has had any of its funds seized or forfeited in an action under any Anti-Money Laundering Laws.

(d) No part of the proceeds from the sale of the Securities hereunder will be used, directly or indirectly, for any improper payments to any governmental official or employee, political party, official of a political party, candidate for political office, official of any public international organization or anyone else acting in an official capacity, in order to obtain, retain or direct business or obtain any improper advantage.

5.1	Registration.

(a) The Company shall use its commercially reasonable efforts to (i) cause to be prepared and filed with the SEC a shelf registration statement on Form S-3 (or, if the Company is not eligible to use such form, Form S-1) (the “Registration Statement”) within ninety (90) days of the Closing Date (the “Filing Date”) for purposes of registering for sale to the public the Registrable Securities, and (ii) cause such Registration Statement to be declared effective (including, without limitation, the execution of any required undertaking to file post-effective amendments, appropriate qualifications or exemptions under applicable Blue Sky or other state securities Laws and appropriate compliance with applicable securities laws, requirements or regulations) under the Securities Act by the SEC as soon as practicable thereafter and in any event no later than one hundred fifty (150) days after the Closing Date. The Company shall not be obligated to enter into any underwriting agreement for the sale of any of the Registrable Securities.

transaction, or negotiations, discussions or pending proposals with respect thereto or (ii) the Registration Statement and any prospectus contains or would contain a material misstatement of fact or omission as a result of an event that has occurred or is continuing, the Company shall be entitled to postpone for the shortest reasonable period of time (but not exceeding one hundred eighty (180) days from the date of such determination of the Board of Directors of the Company), the filing or effectiveness of such Registration Statement and shall promptly give the Holders written notice of such determination, and, upon request of the Holders, a general statement of the reasons for such postponement and an approximation of the anticipated delay.

(a) subject to Section 5.5, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities Laws which the Company determines to obtain, continuously effective until the earlier of the following: (i) such time as all of the Registrable Securities are sold, or (ii) such time as all Warrant Shares and any other shares of Common Stock held by the Holders cease to be Registrable Securities.

(b) advise the Holders within five (5) Business Days:

(iii) of the issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for such purpose;

(iv) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(v) of the occurrence of any event that requires the making of any changes in the Registration Statement or the prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the prospectus, in the light of the circumstances under which they were made) not misleading;

(c) use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement at the earliest possible time;

(f) prior to any public offering of Registrable Securities pursuant to any Registration Statement, promptly take such actions as may be necessary to register or qualify or obtain an exemption for offer and sale under the securities or Blue Sky Laws of such jurisdictions as any such Holders reasonably request in writing, provided that the Company shall not for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified, to consent to general service of process in any such jurisdiction or to become subject to taxation in any jurisdiction in which it is not then already subject to taxation, and do any and all other acts or things reasonably necessary or advisable to enable the offer and sale in such jurisdictions of the Registrable Securities covered by such Registration Statement;

(g) upon the occurrence of any event contemplated by Section 5.3(b)(v), the Company shall use its best efforts to promptly prepare a post-effective amendment to the Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, the prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(h) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the SEC that could affect the sale of the Registrable Securities;

5.4	Indemnification.

(a) To the extent permitted by Law, the Company shall indemnify each Holder and each Person controlling such Holder within the meaning of Section 15 of the Securities Act, with respect to which any registration that has been effected pursuant to this Agreement, against all claims, losses, damages and liabilities (or action in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 5.4(c)), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in the Registration Statement, prospectus, any amendment or supplement thereof or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were made, or any violation by the Company of any rule or regulation promulgated by the Securities Act applicable to the Company and relating to any action or inaction required of the Company in connection with any such registration and will reimburse each Holder and each Person controlling such Holder for reasonable legal and other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action as incurred; provided, however, that the Company will not be liable in any such case to the extent that any untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Holder; provided further, however, that the Company will not be liable in any such case where the claim, loss, damage or liability arises out of or is related to the failure of the Holder to comply with the covenants and agreements contained in this Agreement respecting sales of Registrable Securities.

(b) Each Holder will severally (but not jointly), if Registrable Securities held by such Holder are included in the securities as to which such registration is being effected, indemnify the Company, each of its directors and officers and each Person who controls the Company within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 5.4(c)), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in the Registration Statement, prospectus, or any amendment or supplement thereof, or based on any omission (or alleged omission) to

state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were made, and will reimburse the Company, such directors and officers and each Person controlling the Company for reasonable legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action as incurred, in each case to the extent, but only to the extent, that such untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Holder; provided that the indemnity shall not apply to the extent that such claim, loss, damage or liability results from the fact that the Final Prospectus was not made available to the Person or entity asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act and the Final Prospectus would have cured the defect giving rise to such loss, claim, damage or liability. Notwithstanding the foregoing, a Holder’s aggregate liability pursuant to this Section 5.4(b) and Section 5.4(d) shall be limited to the net amount received by the Holder from the sale of the Registrable Securities.

(c) Each party entitled to indemnification under this Section 5.4 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party (at its expense) to assume the defense of any such claim or any litigation resulting therefrom, provided, however, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense provided that all legal and other expenses incurred by the Indemnified Party in connection therewith shall be at such Indemnified Party’s expense, and, provided further, that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement, unless such failure is materially prejudicial to the Indemnifying Party in defending such claim or litigation. An Indemnifying Party shall not be liable for any settlement of an action or claim effected without its written consent (which consent will not be unreasonably withheld). No Indemnifying Party, in its defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation.

(d) If the indemnification provided for in this Section 5.4 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage or expense referred to therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party thereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative

fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

5.5	Certain Obligations of Holders.

(a) Each Holder agrees that, upon receipt of any notice from the Company of the happening of any event requiring the preparation of a supplement or amendment to a prospectus relating to Registrable Securities so that, as thereafter delivered to the Holders, such prospectus shall not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, each Holder will forthwith discontinue disposition of Registrable Securities pursuant to the Registration Statement and prospectus contemplated by Section 5.1 until its receipt of copies of the supplemented or amended prospectus from the Company and, if so directed by the Company, each Holder shall deliver to the Company all copies, other than permanent file copies then in such Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice.

(b) Each Holder shall suspend, upon request of the Company, any disposition of Registrable Securities pursuant to the Registration Statement and prospectus contemplated by Section 5.1 during (i) any period not to exceed one ninety (90) day period within any one twelve (12) month period (the “Ninety Day Period”) the Company requires in connection with a primary underwritten offering of equity securities so long as the Holders are permitted to participate in such primary underwritten offering on a pro rata basis based on the number of shares of Common Stock they hold at such time relative to the Company’s total number of outstanding shares of Common Stock at such time (provided, however, that, to the extent the underwriters for such offering advise the Holders that marketing factors require a limitation of the number of shares of Common Stock that may be included in such underwritten offering, the right of the Holders to participate in such offering on a pro rata basis as described above shall be reduced or eliminated and such Holder shall nonetheless remain obligated to suspend its disposition of Registrable Securities pursuant to the Registration Statement and prospectus contemplated by Section 5.1 for up to the entirety of the Ninety Day Period), and (ii) any period, not to exceed one ninety (90) day period per twelve (12) month period, when the Company determines in good faith that offers and sales pursuant thereto should not be made by reason of the presence of material undisclosed circumstances or developments with respect to which the disclosure that would be required in such a prospectus is premature or would have a Material Adverse Effect on the Company.

(c) As a condition to the inclusion of its Registrable Securities, each Holder shall furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may request in writing, including completing a Registration Statement questionnaire substantially in the form provided by the Company, or as shall be required in connection with any registration referred to in this Agreement.

(d) Each Holder acknowledges and agrees that the Registrable Securities sold pursuant to the Registration Statement are not transferable on the books of the Company unless any stock certificate submitted to the transfer agent evidencing such Registrable Securities is accompanied by a certificate reasonably satisfactory to the Company to the effect that (i) the Registrable Securities have been sold in accordance with such Registration Statement and (ii) the requirement of delivering a current prospectus has been satisfied.

(e) Each Holder agrees not to take any action with respect to any distribution deemed to be made pursuant to such Registration Statement which would constitute a violation of Regulation M under the Exchange Act or any other applicable rule, regulation or Law.

(f) At the end of the Registration Period the Holders shall discontinue sales of shares pursuant to such Registration Statement upon receipt of notice from the Company of its intention to remove from registration the shares covered by such Registration Statement which remain unsold, and such Holders shall notify the Company of the number of shares registered which remain unsold immediately upon receipt of such notice from the Company.

5.6

With a view to making available to the Holders the benefits of certain rules and regulations of the SEC which at any time permit the sale of the Notes, the Warrants or the Registrable Securities to the public without registration, so long as the Holders still own the Notes, the Warrants or any Registrable Securities, the Company shall use its commercially reasonable efforts to:

Form of Legal Opinion of Special Counsel to the Company

Capitalized terms used in this Annex have the respective meanings (i) set forth below, or (ii) if not so set forth, given to such terms in the Purchase Agreement to which this Annex is attached (the “Purchase Agreement”).

“Applicable Agreements” means those agreements and other instruments included among the agreements and other instruments that have been filed or listed as exhibits to any of the Exchange Act Documents.

“Applicable Orders” means those orders or decrees of governmental authorities listed in Schedule [ ] to this opinion letter, which have been certified by officers of the Company as being every order or decree of any governmental authority by which the Company or any of its subsidiaries or any of their respective properties is bound, that is material in relation to the business, operations, affairs, financial condition, assets, or properties of the Company and its subsidiaries, considered as a single enterprise. [However, officers of the Company have certified to us that there are no Applicable Orders.]

“Transaction Agreements” means the Purchase Agreement, the Indenture, the Notes, the Warrant Agreement and the Warrants.

References herein to “applicable laws” mean those laws, rules and regulations that, in our experience, are normally applicable to transactions of the type contemplated by the Transaction Agreements, without our having made any special investigation as to the applicability of any specific law, rule or regulation, and that are not the subject of a specific opinion herein referring expressly to a particular law or laws; provided however, that such references do not include any municipal or other local laws, rules or regulations, or any antifraud, environmental, labor, securities (except as set forth in paragraphs 10 and 11 below), tax, insurance or antitrust, laws, rules or regulations.

1. The Company is validly existing as a corporation and in good standing under the laws of the State of Delaware.

2. The Company has the corporate power and corporate authority under the laws of the State of Delaware to (i) execute and deliver, and incur and perform all of its obligations under, each of the Transaction Agreements and (ii) carry on its business and own its properties as described in the Exchange Act Documents.

3. Each of the Transaction Agreements has been duly authorized, executed and delivered by the Company.

4. None of (i) the execution and delivery of, or the incurrence or performance by the Company of its obligations under, each of the Transaction Agreements, each in accordance with its terms and (ii) the offering, issuance, sale and delivery of the Securities pursuant to the Purchase Agreement, (A) constituted, constitutes or will constitute a violation of the Company’s Charter Documents, (B) constituted, constitutes or will constitute a breach or violation of, or a

default (or an event which, with notice or lapse of time or both, would constitute such a default), under any Applicable Agreement, (C) resulted, results or will result in the creation of any security interest in, or lien upon, any of the property or assets of the Company or any of its subsidiaries pursuant to any Applicable Agreement, (D) resulted, results or will result in any violation of (i) applicable laws of the State of New York, (ii) applicable laws of the State of Texas, (iii) applicable laws of the United States of America or (iii) the General Corporation Law of the State of Delaware or (E) resulted, results or will result in the contravention of any Applicable Order.

5. No Governmental Approval or Filing, which has not been obtained or made and is not in full force and effect, is required to authorize, or is required for the execution and delivery by the Company of, the Transaction Agreements or the incurrence or performance of its obligations thereunder, or the enforceability of any of such Transaction Agreements against the Company. As used in this paragraph, “Governmental Approval or Filing” means any consent, approval, license, authorization or validation of, or filing, recording or registration with, any executive, legislative, judicial, administrative or regulatory body of the State of New York, the State of Texas, the State of Delaware or the United States of America, pursuant to (i) applicable laws of the State of New York, (ii) applicable laws of the State of Texas, (iii) the General Corporation Law of the State of Delaware or (iv) applicable laws of the United States of America.

6. Each of the Transaction Agreements constitutes a valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, under applicable laws of the State of New York.

7. In a case properly argued and presented, a Texas state court having jurisdiction and applying Texas law (including, without limitation, the conflict of law principles set forth in Chapter 271 of the Texas Business and Commerce Code) or a United States federal court having jurisdiction and applying Texas law (including, without limitation, the conflict of law principles set forth in Chapter 271 of the Texas Business and Commerce Code) would enforce the provisions contained in the Transaction Agreements that purport to require that the rights and obligations of the parties thereto are to be governed by and construed in accordance with the laws of the State of New York.

8. In a case properly argued and presented, a New York state court having jurisdiction and applying New York law (including, without limitation, New York General Obligations Law Section 5-1401) or a United States federal court having jurisdiction and applying New York law (including, without limitation, New York General Obligations Law Section 5-1401) would enforce the provisions contained in the Transaction Agreements that purport to require that the rights and obligations of the parties thereto are to be governed by and construed in accordance with the laws of the State of New York.

9. The holders of outstanding shares of capital stock of the Company are not entitled to any preemptive rights under the Company’s Charter Documents or any Applicable Agreement, to subscribe for the Securities or the shares of the Company’s Common Stock issuable upon the exercise of any of the Warrants. The shares of Common Stock issuable upon exercise of the Warrants at the initial exercise price provided in the Warrant Agreement and the

Annex C - Page 2

Warrants have been duly authorized by the Company and reserved for issuance upon such exercise, and upon issuance of such shares of Common Stock pursuant to the exercise of the Warrants in accordance with the terms of the Warrant Agreement and the Warrants at exercise prices at or in excess of the par value of such shares of Common Stock, such shares of Common Stock will be validly issued, fully paid and nonassessable.

10. The issuance, sale and delivery by the Company of the Securities to the Purchasers in the manner contemplated by the Purchase Agreement, do not require registration under the Securities Act of 1933, as amended, and such issuance, sale and delivery of the Notes do not require the Purchase Agreement or the Indenture to be qualified under the Trust Indenture Act of 1939, as amended.

11. Each of the Company and its Subsidiaries is not, and immediately after giving effect to the issuance and sale of the Securities occurring today and the application of proceeds therefrom as described in the Purchase Agreement, will not be, an “investment company” within the meaning of said term as used in the Investment Company Act of 1940, as amended.

Schedule 3.10

Disclosed Litigation

In May 2012, Newfield Production Company (“Newfield”) filed notice pursuant to the Purchase and Sale Agreement between Harvest (US) Holdings, Inc. (“Harvest US”) and ▇▇▇▇▇▇▇▇ dated March 21, 2011 (the “PSA”) of a potential environmental claim involving certain ▇▇▇▇▇ drilled on the Antelope Project. The claim asserts that locations constructed by Harvest were built on, within, or otherwise impact or potentially impact wetlands and other water bodies. The notice asserts that to the extent of potential penalties or other obligations that might result from potential violations that Harvest US indemnifies Newfield pursuant to the PSA. In June 2012, we provided Newfield with notice pursuant to the PSA (1) denying that Newfield has any right to indemnification from us, (2) alleging that any potential environmental claim related to Newfield’s notice would be an assumed liability under the PSA and (3) asserting that Newfield indemnify us pursuant to the PSA. We dispute ▇▇▇▇▇▇▇▇’▇ claims and plan to vigorously defend against them. We are unable to estimate the amount or range of any possible loss.

Anti-Money Laundering Law Events

On May 31, 2011, the United Kingdom branch of our subsidiary, Harvest Natural Resources, Inc. (UK), initiated a wire transfer of approximately $1.1 million ($0.7 million net to our 66.667 percent interest) intending to pay Libya Oil Gabon S.A. (“LOGSA”) for fuel that LOGSA supplied to our subsidiary in the Netherlands, Harvest Dussafu, B.V., for the company’s drilling operations in Gabon. On June 1, 2011, our bank notified us that it had been required to block the payment in accordance with the U.S. sanctions against Libya as set forth in Executive Order 13566 of February 25, 2011, and administered by OFAC, because the payee, LOGSA, may be a blocked party under the sanctions. The bank further advised us that it could not release the funds to the payee or return the funds to us unless we obtain authorization from OFAC. On October 26, 2011, we filed an application with OFAC for return of the blocked funds to us. Unless that application is approved, the funds will remain in the blocked account, and we can give no assurance when, or if, OFAC will permit the funds to be released. Our October 26, 2011 application for the return of the blocked funds remains pending with OFAC.
