The closing (the “Closing”) of the sale of the Shares shall be effected at the offices of White & Case LLP in Washington, D.C. on December 18, 2006, or as soon as practicable thereafter upon the satisfaction of the conditions set forth in Section 4, or at such other time and place as may be agreed to by IFC and the Company but in no event later than December 29, 2006 (the “Closing Date”).

5.1 Listing of Common Stock. The Company shall use its reasonable best efforts to cause the Common Stock to be listed on the American Stock Exchange (or, if such listing cannot be obtained, upon NASDAQ or another exchange acceptable to IFC) as soon as practicable following the date hereof. The Company shall use its reasonable best efforts to cause the Shares to be listed or included on each securities exchange or automated quotation system on which similar securities issued by the Company are then listed or included.

5.2 Shelf Registration. The Company shall prepare and file or cause to be prepared and filed with the SEC, as soon as practicable but in any event no later than sixty (60) days after the Closing Date (the “Registration Statement Filing Deadline”), a Registration Statement on Form S-1 (or such other form as the Company is then eligible to use) for an offering to be made on a delayed or continuous basis pursuant to Rule 415 of the Securities Act registering the resale from time to time by IFC of the Shares pursuant to plans of distribution acceptable to IFC (the “Registration Statement”). IFC agrees to promptly provide to the Company, in writing, such information as the Company may reasonably request for inclusion in the Registration Statement. The Company shall use its reasonable best efforts to cause the Registration Statement to be declared effective under the Securities Act no later than sixty

(60) days after its filing date or in the event of SEC review, ninety (90) days from the date of filing (the “Effectiveness Deadline”), and to keep such Registration Statement continuously effective under the Securities Act until the earlier of (i) the date on which all Shares covered by the Registration Statement may be sold without volume restrictions pursuant to either Rule 144 or Rule 144(k) as determined by counsel to the Company pursuant to a written opinion letter to such effect, addressed to the Company’s transfer agent and to IFC, or (ii) such date as all Shares registered on such Registration Statement have been resold (the earlier to occur of (i) or (ii) is the “Registration Termination Date”).

(a) If a Registration Statement ceases to be effective for any reason at any time prior to the applicable Registration Termination Date, the Company shall use its reasonable best efforts to reinstate the effectiveness thereof.

(b) The Company shall supplement and amend the Registration Statement if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Registration Statement, if required by the Securities Act or, to the extent to which the Company does not reasonably object, as requested by IFC.

(c) All Registration Expenses incurred in connection with the registrations pursuant to this Section 5.2 shall be borne by the Company. “Registration Expenses” shall mean all expenses incurred by the Company in complying with this Section 5.2 including, without limitation, all registration and filing fees, printing expenses, fees and disbursements of counsel for the Company, blue sky fees and expenses, and the expense of any special audits incident to or required by any such registration (but excluding the compensation of regular employees of the Company which shall be paid in any event by the Company and Selling Expenses, as defined hereinafter). All Selling Expenses incurred in connection with any registrations hereunder, shall be borne by IFC. “Selling Expenses” shall mean all brokerage and selling commissions applicable to a sale of the Shares pursuant to the Registration Statement.

(d) The Company may suspend sales of Shares pursuant to the Registration Statement for a period of not more than thirty (30) days during any six (6) month period in the event it determines in good faith that such Registration Statement contains or may contain an untrue statement of material fact or omits or may omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided that the Company shall promptly amend such Registration Statement in order to correct any untrue statement and/or ensure that such Registration Statement is not misleading; provided further that subject to the time limitations set forth above, the Company may delay such amendment if the Company determines that such delay is in the best interest of the Company in order to avoid premature public announcements of potential acquisitions or other extraordinary transactions. At the time the Registration Statement is declared effective, IFC shall be named as a selling securityholder in the Registration Statement and the related prospectus in such a manner as to permit IFC to deliver such prospectus to purchasers of Shares in accordance with applicable law.

(e) The Company shall promptly furnish to IFC, upon request and without charge, (A) any correspondence from the SEC or the staff of the SEC to the Company or its representatives relating to any Registration Statement, and (B) after the same is prepared and filed with the SEC, one copy of any Registration Statement and any amendment(s) thereto,

including financial statements and schedules, all documents incorporated therein by reference and all exhibits.

(f) The Company shall furnish to IFC such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as it may reasonably request in order to facilitate the disposition of the Shares owned by it.

(g) The Company shall use its reasonable best efforts to register and qualify the securities covered by such registration statement under such other securities or blue sky laws of such jurisdictions as shall be reasonably requested by IFC, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions.

(h) The Company shall immediately notify IFC at any time when a prospectus relating to a Registration Statement which covers the Shares is required to be delivered under the Securities Act regarding the happening of any event as a result of which the prospectus included in such Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; provided, however, that, subject to Section 5.2(d) the Company shall promptly amend such Registration Statement in order to correct any untrue statement and/or ensure that such Registration Statement is not misleading.

5.3 Piggyback Registration.

(a) Whenever the Company proposes to file a registration statement under the Securities Act with respect to an offering of Common Stock (i) following the first anniversary of the Closing Date, for the Company’s own account (other than a registration statement on Form S-4 or S-8 (or any substitute form that may be adopted by the SEC)), or (ii) at any time, for the account of any of its holders of Common Stock, the Company shall give notice of such proposed filing to IFC as soon as practicable (but in no event less than thirty (30) days before the anticipated filing date); provided, however, if any Person other than the Company is permitted to participate in an offering described in clause (i) prior to the first anniversary of the Closing Date, the Company shall give notice of such proposed filing to IFC. Such notice shall offer to IFC the opportunity to register such Shares as IFC may request on the same terms and conditions as the Company’s or such holders’ Common Stock. At the request of IFC received by the Company within twenty days after the receipt of such notice by the Company, the Company shall include, subject to the terms and conditions hereof, the number of Shares that IFC shall have requested to be so included (a “Piggyback Registration”). The Company shall require the lead or managing underwriter, if any, of any proposed underwritten offering to permit the Shares requested to be included in the Piggyback Registration to include such securities on the same terms and conditions as are applicable to the other securities included therein.

(b) If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise the IFC as a part of the written notice given pursuant to Section 5.3(a). In such event the right of IFC to

registration pursuant to Section 5.3 shall be conditioned upon IFC’s participation in such underwriting and the inclusion of IFC’s Shares in the underwriting to the extent provided herein. IFC and all other Persons proposing to distribute their securities through such underwriting shall (together with the Company and the other Persons distributing their securities through such underwriting) enter into an underwriting agreement in customary form with a nationally recognized underwriter selected for underwriting by the Company. Notwithstanding anything to the contrary contained herein, if the managing underwriter or underwriters of an offering described in Section 5.3(a) shall advise the Company that the size of the offering that IFC, the Company and/or any other Persons intend to make is such that the success of the offering would be materially and adversely affected, then the amount of securities to be offered for the account of IFC and for the account of Persons other than the Company shall be reduced pro rata to the extent necessary to reduce the total amount of securities to be included in such offering to the amount recommended by such managing underwriter or underwriters.

5.4 Termination of Registration Rights. All rights and obligations provided for in Section 5.2 shall terminate on the date on which the Company has no obligation to maintain the effectiveness of the Registration Statement; provided that the rights of IFC under Section 5.2 shall terminate on the earlier of (i) the date on which all Shares covered by the Registration Statement may be sold without volume restrictions pursuant to either Rule 144 or Rule 144(k) as determined by counsel to the Company pursuant to a written opinion letter to such effect, addressed to the Company’s transfer agent and to IFC, or (ii) such date as all Shares registered on such Registration Statement have been resold.

5.5 Reports Under Securities Exchange Act of 1934. With a view to making available to IFC the benefits of Rule 144 and any other rule or regulation of the SEC that may at any time permit IFC to sell securities of the Company to the public without registration or pursuant to a Registration Statement, the Company agrees to:

(a) use its reasonable best efforts to make and keep public information available, as those terms are understood and defined in SEC Rule 144, at all times so long as the Company remains subject to the periodic reporting requirements under Sections 13 or 15(d) of the Exchange Act;

(b) use its reasonable best efforts to take such action as is necessary to enable IFC to utilize Form S-1 or such other registration statement form as may be applicable for the sale of its Shares;

(c) use its reasonable best efforts to file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and

(d) furnish to IFC, so long as IFC owns any Shares, forthwith upon request (i) a written statement by the Company that it has complied with the reporting requirements of the Securities Act and the Exchange Act, or that it qualifies as a registrant whose securities may be resold pursuant to Form S-1 (or such other form as the Company is then eligible to use), (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be

reasonably requested in availing IFC of any rule or regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form.

5.6 Preemptive Right. IFC shall have the right to purchase its pro rata share of New Securities (as defined in this Section 5.6) which the Company may, from time to time, propose to sell and issue. IFC’s pro rata share, for purposes of this right, is the ratio of the Common Stock and Stock Equivalents owned by it immediately prior to the issuance of New Securities to all Common Stock and Stock Equivalents outstanding immediately prior to the issuance of New Securities. This pre-emptive right shall be subject to the following provisions:

(a) “New Securities” shall mean any Common Stock or Stock Equivalents of the Company whether now authorized or not, and securities of any type whatsoever that are, or may become, convertible into, or exchangeable or exercisable for, Common Stock or Stock Equivalents; provided that the term “New Securities” does not include: (i) the Shares and any Common Stock issuable upon conversion, exercise or exchange of Stock Equivalents issued as of the date hereof; (ii) Common Stock issued or issuable in connection with any pro rata stock split or stock dividend of the Company; (iii) Common Stock or Stock Equivalents issued pursuant to the acquisition of another Person by the Company by merger, purchase of all or substantially all of the assets of such Person or other transaction whereby the Company shall become directly or indirectly the owner of more than 50% of the voting power of such Person; or (iv) Common Stock issued or issuable under the Company’s current Long-Term Incentive Compensation Plan.

(b) In the event the Company proposes to undertake an issuance of New Securities, it shall give to IFC certified written notice of its intention, describing the type of New Securities, and their price and the general terms upon which the Company proposes to issue the same. IFC shall have forty-five (45) days after any such notice is mailed or delivered to agree to purchase its pro rata share of such New Securities for the price and upon the terms specified in such notice by giving written notice to the Company and stating therein the quantity of New Securities to be purchased.

5.7 IFC Policy Covenants.

(a) The Company and its Subsidiaries shall:

(i) undertake their Operations in compliance with (i) the Action Plan and (ii) the IFC Performance Standards;

(ii) periodically review the form of the Annual Monitoring Report and advise IFC as to whether revision of the form is necessary or appropriate in light of changes to the Operations of the Company or any Subsidiary, or in light of environmental or social risks identified by the Company’s S&E Management System, and revise the form as agreed with IFC;

(iii) use all reasonable efforts to ensure the continuing operation of the S&E Management System to assess and manage the social and environmental performance of the Operations in compliance with the IFC Performance Standards;

(iv) within sixty (60) days after the end of each fiscal year, deliver to IFC an Annual Monitoring Report confirming compliance with the Action Plan, the social and environmental covenants set forth in this Section 5.7 and Applicable S&E Law or, as the case may be, identifying any non-compliance or failure, and the actions taken to remedy any such deficiency, in form and substance satisfactory to IFC; provided the Company may supplement any Annual Monitoring Report with such information as may be useful to enhance its clarity and/or to better illustrate the Company’s performance over time (e.g., charts, graphs);

(v) within three days after its occurrence, notify IFC of any social, labor, health and safety, security or environmental incident, accident or circumstance having, or which could reasonably be expected to have, any material impact on the implementation or operation of the Operations in compliance with the IFC Performance Standards or a Material Adverse Effect, specifying in each case the nature of the incident, accident, or circumstance and the impact or effect arising or likely to arise therefrom, and the measures the Company is taking or plans to take to address them and to prevent any future similar event; and keep IFC informed of the on-going implementation of those measures;

(vi) not amend the Action Plan in any material respect without the prior written consent of IFC; and

(vii) not undertake, or invest in any Person engaged in, any of the activities set forth on Annex B.

(b) The Company hereby agrees that no party hereto shall make (and no party hereto shall authorize or permit any Affiliate or any other Person acting on its behalf to make) any Prohibited Payment. Each of the parties hereto further covenants that should IFC notify the Company of its concern that there has been a violation of the provisions of this paragraph, the Company shall cooperate in good faith with it and its representatives in determining whether such a violation has occurred, and shall respond promptly and in reasonable detail to any notice from IFC, and shall furnish documentary support for such response upon IFC’s request.

(c) The Company will disclose the tax, royalty and other material payments made annually by the Company or any Affiliate to local and/or national governments in the Republic of Peru or the Republic of Ecuador under the applicable upstream license contracts.

5.8 Minimum Insurance. The Company shall cause its operations in Peru to effect and maintain the insurance coverage specified in Annex C at all appropriate and necessary times during the period in which the IFC owns Common Stock, under forms of policies and with insurers and reinsurers acceptable to IFC.

5.9 Minority Rights. So long as IFC holds Shares comprising 5% or more of the Common Stock, neither the Company nor its Subsidiaries shall approve, authorize or enter into a transaction with respect to any of the following without the prior written consent of IFC (such consent not to be unreasonably withheld):

(a) the consolidation or merger of the Company or any Subsidiary; provided that IFC’s consent will not be required in the case of a merger of the Company if the shareholders of the Company immediately preceding such merger continue to hold more than 50% of the equity of the surviving entity, or in the case of a merger of a Subsidiary of the Company, the surviving entity in such merger continues to be a Subsidiary of the Company;

(b) the sale of all or substantially all of the assets of the Company or any Subsidiary; provided that IFC’s consent will not be required in the case of the sale of assets to a direct or indirect Subsidiary of the Company;

(c) the transformation of the Company or any Subsidiary into another form of entity; or

(d) change the nature of the Company’s or any of its Subsidiaries’ business as currently conducted.

5.10 Most Favored Nation (MFN) Status. If the Company enters into any subscription agreement, stock purchase agreement or other agreement on or after the date hereof and prior to the Closing to or with any Person that establishes rights or benefits in favor of such Person with respect to the acquisition of Common Stock or Stock Equivalents that are more favorable in any material respect to such Person than the rights and benefits established in favor of IFC herein, the Company will extend to IFC such rights and benefits established by such subscription agreement, stock purchase agreement or other agreement.

5.11 Use of Proceeds. The Company shall not use the proceeds of the subscription of the Shares by IFC in reimbursement of, or for expenditures in the territories of any country which is not a member of the World Bank or for goods produced in or services supplied from any such country.

Section 6. Indemnification.

6.1 Indemnification. The Company will indemnify and hold harmless IFC, its officers, directors, employees, partners, affiliates, agents, representatives and legal counsel (collectively, “IFC Agents”) with respect to which registration, qualification or compliance has been effected pursuant to Section 5.2 or 5.3, against all claims, losses, damages and liabilities (or actions in respect thereof) against or incurred by IFC or IFC Agents arising out of or based on (A) (i) any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, offering circular or other similar document or any amendments or supplements thereto (including any related registration statement and amendments or supplements thereto, notification or the like) incident to any such registration, qualification or compliance, 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 the light of the circumstances under which they were made, and will reimburse IFC and IFC Agents for any reasonable legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damages, liability or action, as incurred, or (ii) any violation by the Company of any federal, state or common law rule or regulation applicable to the Company in connection with any such registration, qualification or

compliance, and will reimburse IFC, and IFC Agents, for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action; and (B) any breach of any covenant, agreement, representation or warranty of the Company in this Agreement; provided, however, that the Company shall not be liable under this Section 6: (a) in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission based upon written information furnished to the Company by an instrument duly executed by IFC and stated to be specifically for use in a Registration Statement, (b) for any amount paid in settlement of claims without the Company’s written consent (which consent shall not be unreasonably withheld), or (c) with respect to clause (B) of this Section 6.1, to the extent that it is finally judicially determined that such claim, loss, damage, liability or expense resulted primarily from the willful misconduct, gross negligence or bad faith of IFC; provided, further, that if and to the extent that such indemnification is held, by final judicial determination to be unenforceable, in whole or in part, for any reason, the Company shall make the maximum contribution to the payment and satisfaction of such indemnified claim, loss, damage, liability or expense. In connection with the obligation of the Company to indemnify for expenses as set forth in clause (B) of this Section 6.1, if an indemnified party is reimbursed hereunder for any expenses, such reimbursement of expenses shall be refunded to the extent it is finally judicially determined that the claim, loss, damage, liability or expense in question resulted primarily from the willful misconduct, gross negligence or bad faith of such indemnified party.

6.2 Notification; Procedure.

(a) IFC shall give notice to the Company promptly after it has received written notice of any claim as to which indemnity may be sought, and shall permit the Company to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Company, who shall conduct the defense of such claim or litigation, shall be approved by IFC (whose approval shall not be unreasonably withheld). IFC may participate in such defense with separate counsel at its expense; provided, however, that the Company shall bear the expense of such separate counsel if representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interest between the Company and IFC. The failure of IFC to give notice within a reasonable period of time as provided herein shall relieve the Company of its obligations under this Section 6, with respect to any expenses incurred by IFC or IFC’s Agents before the date of such notice and to the extent that such failure to give notice shall materially adversely prejudice the Company in the defense of any such claim or any such litigation. The Company, in the defense of any such claim or litigation, shall not, except with the consent of IFC, 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 IFC of a release from all liability in respect to such claim or litigation.

(b) If the indemnification provided for in this Section 6 is held to be unavailable to IFC with respect to any loss, liability, claim, damage or expense, then the Company, in lieu of indemnifying IFC hereunder, shall contribute to the amount paid or payable by IFC as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and of IFC on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations; provided, that in no event shall

any contribution by IFC under this Section 6 exceed the net proceeds from the offering received by IFC. The relative fault of the Company and of IFC 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 Company or by IFC and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission.

(c) All indemnification rights hereunder shall survive the execution and delivery of the Transaction Documents and the subscription contemplated herein for the applicable statute of limitations, notwithstanding any inquiry or examination made for or on behalf of, or any knowledge of IFC or the acceptance by IFC of any certificate or opinion.

(d) IFC shall furnish to the Company such information regarding IFC and the distribution proposed by IFC as the Company may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification or compliance referred to in this Section 6.

Section 7. Survival of Representations and Warranties. All representations, warranties and agreements made by the Company and IFC in this Agreement or in any certificate or other instrument delivered pursuant hereto shall survive the Closing and any investigation and discovery by the Company or by IFC, as the case may be, made at any time with respect thereto.

Section 8. Miscellaneous Provisions.

8.1 Deliveries. The Company and IFC hereby covenant and agree to use their respective reasonable best efforts to perform each of their obligations hereunder, to deliver all certificates and to satisfy all other conditions set forth in this Agreement and to close the transactions contemplated by this Agreement on the Closing Date.

8.2 Successors and Assigns. This Agreement is executed by, and shall be binding upon and inure to the benefit of, the parties hereto and each of their respective successors and assigns; provided, however, that neither this Agreement nor any right pursuant hereto nor interest herein shall be assignable except (a) by the Company with the consent of IFC, (b) by the Company in connection with a merger, consolidation or sale of all or substantially all of its assets, (c) by IFC with the prior written consent of the Company or (d) the assignment of the rights of IFC set forth in Sections 5.1 through 5.6 by IFC in connection with a sale or other transfer of the Shares. None of the provisions of this Agreement shall be for the benefit of or enforceable by any other person.

8.6 Governing Law; Forum.

(a) This Agreement shall be governed by, and construed and enforced in accordance with, the laws of the State of New York applicable to contracts entered into and to be wholly performed therein.

(b) Any dispute, controversy or claim arising out of, relating to, or in connection with this Agreement, including any question regarding its existence, validity or termination, shall be referred to and finally resolved by arbitration. The arbitration shall be conducted in accordance with the Rules of Arbitration of the International Chamber of Commerce (the “ICC”) in effect at the time the arbitration is initiated, except as they may be modified herein or by mutual agreement of the parties. The place of arbitration shall be New York, New York. The arbitration shall be conducted in the English language.

(c) The arbitration shall be conducted by three arbitrators. The claimant shall nominate one arbitrator and the respondent shall nominate another arbitrator. If either side fails to nominate an arbitrator within 30 days of receipt of the request for arbitration, then that arbitrator shall be nominated by the ICC. The first two arbitrators nominated in accordance with this provision shall nominate a third arbitrator within 30 days after the nomination of the later-nominated of those two arbitrators. When the third arbitrator has accepted the nomination, the two arbitrators making the nomination shall promptly notify the parties of the nomination. If the first two arbitrators nominated fail to (i) nominate a third arbitrator within the time period prescribed above or (ii) notify the parties of the acceptance of a third arbitrator within 10 days after the time period prescribed above, then the ICC shall nominate the third arbitrator and shall promptly notify the parties of the nomination. The third arbitrator shall act as chair of the tribunal.

(d) The arbitration tribunal shall have the authority to make such orders for interim relief, including injunctive relief, as it may deem appropriate, and any interim measures ordered by the arbitrators shall be specifically enforced by any court of competent jurisdiction. Each party hereto retains the right to seek interim measures from a judicial authority, and any such request shall not be deemed incompatible with the agreement to arbitrate or a waiver of the right to arbitrate. The parties agree that, to the extent permitted by applicable law, any ruling by the arbitration tribunal on interim measures shall be deemed to be a final award with respect to the subject matter of the ruling and shall be fully enforceable as such.

(e) Subject to paragraph (h) below, the arbitration tribunal shall have the authority to order such production of documents as may reasonably be requested by any party or by the tribunal itself.

(f) The arbitration award shall be in writing, state the reasons for the award, and be final and binding on the parties. The award may include an award of costs, including reasonable attorneys’ fees and disbursements. Judgment upon the award may be entered by any court having jurisdiction thereof or having jurisdiction over the relevant party or its assets.

(g) Each party shall use its commercially reasonable efforts to ensure the arbitration is concluded as quickly and as efficiently as possible.

(h) Notwithstanding anything to the contrary contained in this Section 8.6, the parties acknowledge and agree that neither any provision of this Section 8.6 nor the submission by IFC to any courts of competent jurisdiction pursuant thereto shall constitute a waiver either before any Authority or court of law of any of the privileges and immunities set

forth in IFC’s Articles of Agreement, including without limitation (i) the immunity of all of the assets of IFC from all forms of seizure, attachment or execution before the delivery of final judgment against IFC, (ii) the immunity of all of the assets of IFC from search, requisition, confiscation, expropriation or any other forms of seizure by executive or legislative action, (iii) the inviolability of IFC’s archives and (iv) the freedom of IFC’s assets from restrictions of any nature.

(i) To the extent that the Company may, in any proceeding brought arising out of or in connection with this Agreement, or the breach, termination or invalidity hereof, be entitled to the benefit of any provision requiring IFC in such suit, action or proceeding to post security for the costs of such party or parties, or to post a bond or to take similar action, the Company hereby irrevocably waives such benefit, in each case to the fullest extent now or in the future permitted under the applicable laws and regulations.

8.7 Attorneys’ Fees. If any party should institute any action to enforce or interpret any term or provision of this Agreement, the party prevailing in such action, after all appeals have been exhausted, shall be entitled to its reasonable attorneys’ fees, out-of-pocket disbursements and all other expenses from the non-prevailing party in such action.

8.8 Entire Agreement. This Agreement (together with all Exhibits and Schedules hereto) constitutes the entire understanding and agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior and contemporaneous written and oral negotiations, discussions, agreements and understandings with respect to such subject matter.

8.9 Section Headings. The section and subsection headings contained in this Agreement are included for convenience only and form no part of the agreement between the parties.

8.10 Amendment. Any amendment of any provision of this Agreement shall be in writing and signed by all parties.

8.11 Remedies and Waivers. No failure or delay by IFC in exercising any power, remedy, discretion, authority or other rights under this Agreement shall waive or impair that or any other right of IFC. No single or partial exercise of any right shall preclude its additional or future exercise. No such waiver shall waive any other right under this Agreement. All waivers or consents given under this Agreement shall be in writing.

8.12 Interpretation. IFC and the Company have participated in the negotiation and drafting of this Agreement. Accordingly, each of the parties hereby waives any statutory provision, judicial precedent or other rule of law to the effect that contractual ambiguities are to be construed against the party who shall have drafted the same.

8.13 Severability. Whenever possible, each provision of this Agreement shall be interpreted in such a manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be or become prohibited or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity without invalidating the remainder of such provision or the remaining provisions of this Agreement, except to the

extent that any provision would clearly be contemplated by the parties to be conditioned upon the validity and enforceability of such invalid or prohibited provision.

8.14 Public Announcements. The Company may, at its option, issue a press release regarding the closing of this offering within a reasonable period after the Closing. Except for such disclosure as the Company is advised by counsel is required to be included in documents filed with the Securities and Exchange Commission or otherwise required by law, the Company shall not use the name of, or make reference to, IFC or any of its Affiliates in any press release or in any public manner (including any reports or filings made by the Company under the Exchange Act) without IFC’s prior written consent which consent shall not be unreasonably withheld.

8.15 Additional Undertakings. The Company hereby agrees to take whatever additional action and to execute whatever additional documents IFC may reasonably deem necessary or advisable in order to carry out or effect one or more of the obligations or restrictions imposed on the parties hereto pursuant to the express provisions of this Agreement.

8.16 English Language. All documents to be furnished or communications to be given or made under this Agreement shall be in the English language or, if in another language, shall be accompanied by a translation into English certified by an authorized officer of the Company, which translations shall be the governing version between the Company and IFC.

8.17 Definitions. Wherever used in this Agreement, unless the context otherwise requires, terms defined in the Recitals shall have the same meanings unless otherwise defined herein, and the terms set forth on Annex A hereto shall have meanings indicated thereon.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed and delivered by their respective representatives hereunto duly authorized as of the date first above written.
