Section 2.6 Misbooking Adjustments. Until [CONFIDENTIAL TREATMENT REQUESTED], the Purchaser may provide, within a commercially reasonable time period, written notice to the Seller of any Misbooking identified or determined to exist at any time with respect to a Trading Contract (a “Misbooked Trading Contract”).

(a) Misbooked Trades Accepted. Within [CONFIDENTIAL TREATMENT REQUESTED] of the date upon which such notice is received by the Seller, the Purchaser shall determine the economic impact of the Misbooked Trading Contract by calculating (i) [CONFIDENTIAL TREATMENT REQUESTED], as of the date notice is given pursuant to this Section 2.6, as determined by reference to the actual characteristics of such Misbooked Trading Contract (giving effect to any errors discovered in connection therewith), less (ii) [CONFIDENTIAL TREATMENT REQUESTED].

Upon rejection of a Misbooked Trading Contract pursuant to this Section 2.6(b), the term “Trading Contracts” shall thereafter not include any such rejected Trading Contract for any purpose hereunder.

(c) Misbooking Calculations. For any determination of the amount payable pursuant to Section 2.6(a) or 2.6(b), Purchaser will act in good faith and use commercially reasonable procedures in order to produce a commercially reasonable result. In determining such amount(s), Purchaser may consider (i) quotations (either firm or indicative) for replacement transactions supplied by one or more Third Parties that may take into account the creditworthiness of the Purchaser or the Seller at the time such quotation is provided and the terms of relevant

documentation, including credit support documentation; (ii) information consisting of relevant market data in the relevant market supplied by one or more Third Parties including relevant rates, prices, yields, yield curves, volatilities, spreads, correlations or other relevant market data in the relevant market; or (iii) information of the type described in clause (i) or (ii) from internal sources (including any Affiliates) if that information is of the same type used by the Purchaser in the regular course of business for the valuation of similar transactions.

(b) Notwithstanding anything to the contrary contained in this Agreement but subject to the requirements of Section 2.7(d), to the extent that the transfer or conveyance of any Transferred Contract or Other Asset to the Purchaser pursuant to this Section 2.7 requires the Consent of a Third Party or Governmental Authorization and such Consent or Governmental Authorization shall not have been obtained prior to the Closing Date:

(c) If the Purchaser has an existing master trading agreement with any Counterparty to a Trading Contract, [CONFIDENTIAL TREATMENT REQUESTED], the Purchaser and the Seller shall have the right to seek the consent of such Counterparty to make the Counterpart Trading Contracts under such Trading Contract subject to the existing master trading agreement between the Purchaser and such Counterparty or to negotiate changes to Seller’s existing master trading agreement or a new master trading agreement with such Counterparty.

(i) this Agreement shall not constitute a novation, assignment or attempted assignment with respect to such Trading Contract at or after the Effective Date;

Thereafter, the sale, transfer and novation of each Post-Mirror Trade shall be conditional on:

(b) If following the Mirror Effective Date, this Agreement is terminated in accordance with the terms and conditions set forth in Article VIII, then following such termination, the Purchaser shall convey, assign and transfer to, and the Seller shall receive, undertake and assume, the ISO Contracts; provided, that if (x) the aggregate marked-to-market value for all such ISO Contracts on the termination date is greater than zero, then the Seller shall pay to the Purchaser an amount equal to such amount, and (y) the aggregate marked-to-market value for all such ISO Contracts on the termination date is less than zero, then the Purchaser shall pay to the Seller an amount equal to the absolute value of such amount.

(a) by mutual written consent of the Seller and the Purchaser;

(b) [CONFIDENTIAL TREATMENT REQUESTED] by the Seller or the Purchaser by not less [CONFIDENTIAL TREATMENT REQUESTED] prior written notice to the other Party (if the terminating Party is not, at such time, in material breach of this Agreement which breach has caused the Closing not to occur prior to such date), if the Closing has not occurred on or before the date such notice is given; or

(c) if the Seller or the Purchaser fails in any material respect to perform or comply with any covenant hereunder or under any Related Agreement to be performed or complied with on or prior to the Closing Date or any representation or warranty made or deemed made by the Seller or the Purchaser proves to be incorrect or misleading in any material respect when made or deemed made and as a result thereof the non-defaulting Party would not under the terms of this Agreement be obligated to consummate the Closing, then, in each case, upon

(e) the Assumed Liabilities.

Section 9.4 Indemnification Procedures.

(a) Asserting a Claim. Without limiting the provisions of Section 9.1, if a Party (an “Indemnified Party”) wishes to assert a claim for indemnification against the other Party (the “Indemnifying Party”), the Indemnified Party shall give notice to the Indemnifying Party, setting forth with particularity the basis for the claim, promptly after the Indemnified Party becomes aware of any fact, condition, or event which gives rise to a Claim for which indemnification may be sought under this Article IX. Failure to notify the Indemnifying Party shall not relieve the Indemnifying Party of liability it may have to the Indemnified Party, except to the extent that the Indemnifying Party has been materially prejudiced by such failure and except that nothing in this Agreement shall be deemed to extend the time limits set forth in Section 9.1. Each Indemnified Party shall use commercially reasonable efforts to mitigate Losses for which it seeks indemnification under this Article IX.

(b) Third Party Claims. If any lawsuit, enforcement action, demand or claim is brought or made by any other Person (a “Third Party Claim”) against an Indemnified Party is the basis for an indemnification claim pursuant to Section 9.2 or Section 9.3, the Indemnifying Party shall be entitled, if it so elects, to take control of the defense and investigation of the Third Party Claim and to employ and engage attorneys of its own choice reasonably acceptable to the Indemnified Party to handle and defend the Third Party Claim, at the Indemnifying Party’s cost, risk and expense. Any election by the Indemnifying Party to take control of the defense and investigation of a Third Party Claim shall not be deemed a waiver of the Indemnifying Party’s right to determine at a later date that the Third Party Claim is not entitled to indemnification under this Agreement, in which case Indemnifying Party may, in the exercise of its sole discretion, determine not to continue to defend that Third Party Claim and any action taken by the Indemnifying Party in connection with that determination shall be undertaken in a manner so as not to materially prejudice the defense or the rights of the Indemnified Party. The Indemnified Party shall cooperate with the Indemnifying Party so as to minimize the risk of any such prejudice. The Indemnified Party shall cooperate in all reasonable respects with the Indemnifying Party and such attorneys in the investigation, trial and defense of any Third Party Claim and any resulting appeal, which shall include: (a) furnishing such records, information and testimony, and

attending such conferences, discovery proceedings, hearings, trials and appeals, as reasonably may be requested in connection with the Third Party Claim, (b) affording access during normal business hours to the Indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information which are reasonably relevant to the Third Party Claim, and (c) making its employees available on a mutually convenient basis to provide additional information and explanation of any material provided to the Indemnifying Party under this Agreement. The Indemnified Party nevertheless may, at its own cost, participate in the investigation, trial and defense of such Third Party Claim or any resulting appeal.

Section 9.5 Settlement or Compromise of Third Party Action; Failure to Assume Defense. If the Indemnifying Party has assumed control of the defense of a Third Party Claim pursuant to Section 9.4, the Indemnifying Party may consent to a settlement or compromise of, or the entry of any monetary judgment arising from the Third Party Claim without the prior consent of the Indemnified Party if, and only if, the proposed settlement, compromise or entry (a) does not contain an admission of guilt or wrongdoing on the part of the Indemnified Party, and (b) does not provide for any remedy or sanction against the Indemnified Party other than the payment of money which the Indemnifying Party agrees to pay and does pay. If the Indemnifying Party does not assume the defense of the Third Party Claim in accordance with Section 9.4 within twenty (20) Business Days after the receipt of notice of the Third Party Claim, the Indemnified Party may, at the Indemnifying Party’s expense, defend the Third Party Claim, but may settle or compromise the Third Party Claim only with the consent of the Indemnifying Party.

Section 9.6 Adjustment to Purchase Price. Amounts paid with respect to indemnification pursuant to Section 9.2(a) or Section 9.3(a) shall be treated as an adjustment to the Purchase Price.

Section 9.7 General Limitations.

(a) Basket. Except in the case of (i) fraud, willful breach or willful misconduct, (ii) Liability for Taxes that are the responsibility of the Seller, and (iii) as provided in Section 10.11, the Seller shall not be liable to any member of the Purchaser Group under Section 9.2(a), and the Purchaser shall not be liable to any member of the Seller Group under Section 9.3(a) unless and until the aggregate cumulative amount of all such Losses exceeds one million dollars ($1,000,000.00), and then shall be liable only to the extent of such excess; provided, however, that the limitation pursuant to this Section 9.7(a) shall not apply (i) to any adjustment to the Purchase Price occurring pursuant to the terms and provisions of Article II, including without limitation with respect to any Misbooking and Identified Transactions, or (ii) to any claim for indemnification arising from a breach of Section 3.2, 3.3, 3.4 or 3.6.

(b) Cap. Except in the case of (i) fraud, willful breach or willful misconduct, (ii) Liability for Taxes that are the responsibility of the Seller, and (iii) as provided in Section 10.11, in no event shall the aggregate cumulative amount of the Seller’s Liabilities under Section 9.2(a),

or the Purchaser’s Liabilities under Section 9.3(a), exceed twenty-five million dollars ($25,000,000.00); provided, however, that the limitation pursuant to this Section 9.7(b) shall not apply (i) to any adjustment to the Purchase Price occurring pursuant to the terms and provisions of Article II, including without limitation with respect to any Misbooking and Identified Transactions, or (ii) to any claim for indemnification arising from a breach of Section 3.2, 3.3, 3.4, 3.6, 3.9, 3.12 or 3.13.

(c) Limitation. NOTWITHSTANDING ANYTHING TO THE CONTRARY ELSEWHERE IN THIS AGREEMENT OR PROVIDED FOR UNDER ANY APPLICABLE LAW, NO PARTY WILL, IN ANY EVENT, BE LIABLE, EITHER IN CONTRACT OR IN TORT, FOR ANY CONSEQUENTIAL, INCIDENTAL, INDIRECT, SPECIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF FUTURE REVENUE, INCOME, OR PROFITS, DIMINUTION OF VALUE, OR LOSS OF BUSINESS REPUTATION OR OPPORTUNITY, RELATING TO THE BREACH OR ALLEGED BREACH OF THIS AGREEMENT OR OTHERWISE, WHETHER OR NOT THE POSSIBILITY OF SUCH DAMAGES HAS BEEN DISCLOSED IN ADVANCE OR COULD HAVE BEEN REASONABLY FORESEEN (“Non-Reimbursable Damages”).

(d) Collateral Sources. In calculating the amount of Losses for which an Indemnified Party is entitled to indemnification under Section 9.2(a) or Section 9.3(a), as applicable, the amount of Losses shall be reduced by (a) any insurance proceeds actually received by the Indemnified Party from an insurance carrier with respect to those Losses, provided that if the Indemnified Party fails to either diligently pursue any such insurance proceeds reasonably available to it or assign a valid right to the Indemnifying Party to pursue such insurance proceeds, the Indemnifying Party’s obligation shall be reduced by the amount of insurance proceeds that would have been reasonably available to and obtainable by the Indemnified Party, (b) any amounts actually received by the Indemnified Party from Third Parties with respect to Losses pursuant to indemnification, warranty or other similar rights, provided that if the Indemnified Party fails to diligently pursue such rights, the Indemnifying Party’s obligation shall be reduced by the amounts available to the Indemnified Party, and (c) Tax benefits. If any Losses for which indemnification is provided under Section 9.2(a) or Section 9.3(a), as applicable, subsequently are reduced by any insurance payment or recovery from a Third Party or loss of Tax benefits, the Indemnified Party promptly shall remit the amount of such reduction to the Indemnifying Party.

(e) Duty to Mitigate Losses. Each Indemnified person shall use its commercially reasonable efforts to mitigate any indemnifiable Losses.

(f) Additional Limitations. Neither Indemnifying Party shall have any indemnification obligations under this Article IX to the extent that, as a result of any gross negligence or willful misconduct of an Indemnified Party after the Closing Date, the amount of Losses subject to indemnification by such Indemnifying Party is exacerbated.

Section 9.8 Exclusive Remedies. Except in the case of fraud, willful breach and willful misconduct, and except as provided in Section 10.11, the Seller and the Purchaser acknowledge and agree that, from and after the Closing, the sole and exclusive remedy for any breach or inaccuracy, or alleged breach or inaccuracy, of any representation or warranty in this Agreement, any certificate delivered pursuant hereto, as the case may be, or any Related Agreement or any covenant or agreement to be performed under this Agreement or any Related Agreement on or prior to the Closing Date, will be indemnification in accordance with this Article IX. In furtherance of the foregoing, the Seller and the Purchaser waive, to the fullest extent permitted by applicable Law, any and all other rights, claims, and causes of action (including rights of contributions, if any) that may be based upon, arise out of, or relate to this Agreement or any such certificate or Related Agreement, or the negotiation, execution, or performance of this Agreement or any Related Agreement (including any tort or breach of contract claim or cause of action based upon, arising out of, or related to any representation or warranty made in or in connection with this Agreement or any Related Agreement or as an inducement to enter into this Agreement or any Related Agreement), known or unknown, foreseen or unforeseen, which exist or may arise in the future, that it may have against the other arising under or based upon any Law (including any such Law under or relating to environmental matters), common law, or otherwise.

Section 9.9 Non-Recourse. No past, present or future director, officer, employee, incorporator, member, partner, stockholder, affiliate, agent or Representative of the Seller or the Purchaser, respectively, or their respective Affiliates, shall have any Liability for any obligations or Liabilities of Seller under this Agreement or the other documents delivered by the Seller or the Purchaser in connection with this Agreement, of or for any claim based on, in respect of, or by reason of, the Contemplated Transactions.

ARTICLE X

GENERAL PROVISIONS

Section 10.1 Expenses. Except as otherwise expressly provided in this Agreement (including in Section 7.3(c)), whether or not the Contemplated Transactions are consummated, the Parties shall bear their own costs and expenses in connection with the preparation, negotiation and execution of this Agreement and the Related Agreements and the consummation of the Contemplated Transactions.

Section 10.2 Public Announcements and Confidentiality. None of the Parties nor their respective Subsidiaries or Affiliates, as the case may be, shall issue or cause the publication of this Agreement, any Related Agreement or any press release or other public announcement or communication with respect to the Contemplated Transactions without the prior written consent of the other Parties hereto, which consent shall not be unreasonably withheld or withdrawn, except to the extent a Party’s counsel deems necessary or advisable in order to comply with any Law or the regulations or policies of any securities exchange or other similar regulatory body (in which case the disclosing Party shall give the other Parties notice as is reasonably practicable of

any required disclosure, shall limit such disclosure to the information required to comply with such Law or regulations, and shall use commercially reasonable efforts to accommodate any suggested changes to such disclosure from the other Parties to the extent reasonably practicable).

Section 10.3 Tax Matters.

(a) Notwithstanding any provision of this Agreement to the contrary, the Purchaser and the Seller shall each pay one-half of all Transfer Taxes incurred in connection with this Agreement and the Contemplated Transactions. The Seller and the Purchaser shall cooperate in timely making all filings, Tax Returns, reports and forms as may be required to comply with the provisions of Tax Laws. For purposes of this Agreement, “Transfer Taxes” shall mean all transfer, sales and use, stamp duty, stamp duty reserve tax, documentary, registration and other such taxes (including all applicable real estate transfer taxes).

(b) Within sixty (60) days of the Closing Date, the Seller shall prepare a draft allocation of the consideration paid for the Transferred Assets among the Transferred Assets, which allocation will also include a determination as to the total gross value of all Transferred Assets that have a positive value, and a determination as to the total gross value of all Transferred Assets that have a negative value (the “Draft Allocation”). The Purchaser shall have sixty (60) days after receipt of the Draft Allocation to object in writing to the Draft Allocation. If the Purchaser does not object to the Draft Allocation within such 60-day period, the Draft Allocation shall become final (the “Final Allocation”). If the Purchaser objects to the Draft Allocation in writing within such 60-day period, the Seller and the Purchaser shall attempt in good faith to resolve the disputed items in the Draft Allocation, and any such resolution shall constitute the Final Allocation. If, within thirty (30) days after the Purchaser has objected in writing to the Draft Allocation, the Parties have not resolved all disputed items with respect to the Draft Allocation, the remaining disputed items shall be resolved by a nationally recognized accounting firm, and its resolution shall constitute the Final Allocation. The Seller and the Purchaser (1) shall be bound by the Final Allocation for purposes of determining any and all consequences with respect to Taxes of the Transferred Assets, (2) shall prepare and file all Tax Returns to be filed with any taxing authority in a manner consistent with the Final Allocation, and (3) shall take no position inconsistent with the Final Allocation in any Tax Return, in any discussion with or Proceeding before any taxing authority, or otherwise.

(c) To the extent necessary to determine the liability for Taxes for a portion of a taxable year or period that begins before and ends after the Closing Date, the determination of the Taxes for the portion of the year or period ending on, and the portion of the year or period beginning after, the Closing Date shall be determined by assuming that the taxable year or period ended as of the close of business on the Closing Date, except that those annual property taxes and exemptions, allowances or deductions that are calculated on an annual basis shall be prorated on a time basis.

Section 10.4 Notices. All notices, Consents, waivers and other communications required or permitted by this Agreement shall be in writing and shall be deemed given to a Party when (a) delivered to the appropriate address by hand or by nationally recognized overnight courier service (costs prepaid), (b) sent by facsimile or e-mail with confirmation of transmission by the transmitting equipment or (c) received or rejected by the addressee, if sent by certified mail, return receipt requested, in each case to the following addresses, facsimile numbers or e-mail addresses and marked to the attention of the person (by name or title) designated below (or to such other address, facsimile number, e-mail address or person as a Party may designate by notice to the other Parties):

Section 10.5 Governing Law; Submission to Jurisdiction; Selection of Forum; Waiver of Trial by Jury. THE AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT SUCH PRINCIPLES WOULD PERMIT OR REQUIRE THE APPLICATION OF LAWS OF ANOTHER JURISDICTION. Each Party hereto agrees that it shall bring any action or Proceeding in respect of any claim arising out of or related to this Agreement or the transactions contained in or contemplated by this Agreement and the Related Agreements, exclusively in the United States District Court for the Southern District of New York (or if subject matter jurisdiction before the federal court does not exist, then before the New York State Supreme Court for the Borough of Manhattan, in New York, New York) (the “Chosen Courts”), and solely in connection with claims arising under this Agreement or the transactions that are the subject of this Agreement or any of the Related Agreements (i) irrevocably submits to the exclusive jurisdiction of the Chosen Courts, (ii) waives any objection to laying venue in any such action or Proceeding in the Chosen Courts, (iii) waives any objection that the Chosen Courts are an inconvenient forum or do not have jurisdiction over any Party hereto and (iv) agrees that service of process upon such Party in any such action or Proceeding shall be effective if notice is given in accordance with Section 10.4 of this Agreement. Each Party hereto irrevocably

designates C.T. Corporation as its agent and attorney in fact for the acceptance of service of process and making an appearance on its behalf in any such claim or Proceeding and for the taking of all such acts as may be necessary or appropriate in order to confer jurisdiction over it before the Chose Courts and each Party hereto stipulates that such consent and appointment is irrevocable and coupled with an interest. Each Party hereto irrevocably waives any and all right to trial by jury in any legal Proceeding arising out of or relating to this Agreement or the Contemplated Transactions.

Section 10.6 Amendment and Waiver. Any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by the Purchaser and the Seller, or in the case of a waiver, by the Party against whom the waiver is to be effective. No failure or delay by any Party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law except as otherwise provided in Article IX hereof.

Section 10.7 Entire Agreement.

(a) This Agreement, together with the Related Agreements, supersedes all prior agreements, whether written or oral, between the Parties with respect to its subject matter (including any letter of intent between the Parties related to the subject matter of this Agreement) and constitutes (along with the Schedules, Exhibits and other documents delivered pursuant to this Agreement) the entire agreement between the Parties with respect to its subject matter except for the Confidentiality Agreement, which shall remain in full force and effect until the Closing.

(b) In the case of any conflict between this Agreement and any of the Related Agreements, the relevant Related Agreement shall prevail except as expressly set forth in such Related Agreement.

Section 10.8 Assignments, Successors and No Third-Party Rights. No Party may, in whole or in part, assign any of its rights or interests or delegate any of its obligations under this Agreement without the prior written consent of both the Purchaser and the Seller, and any attempt to do so will be void; provided, however, that without prior written consent either the Purchaser or the Seller may pursuant to a corporate reorganization assign any of its rights or interests under this Agreement to any Affiliate so long as (a) the assignee is bound by this Agreement, (b) the assignee remains an Affiliate of the Purchaser or the Seller, as the case may be, and (c) such assignment does not prevent or materially impede, interfere with, or delay the Contemplated Transaction, increase the costs to non-assigning Party of the consummation of Contemplated Transaction or result in any Seller or its Affiliates incurring a Tax Liability in excess of the Tax Liability Seller or its Affiliates would otherwise incur without such designation. Subject to the preceding sentence, and except as otherwise expressly provided in

Sections 9.2 and 9.3, this Agreement will apply to, be binding in all respects upon and inure to the benefit of the successors and permitted assigns of the Parties. Nothing expressed or referred to in this Agreement will be construed to give any Person other than the Parties to this Agreement any legal or equitable right, remedy or claim under or with respect to this Agreement or any provision of this Agreement, except such rights as shall inure to a successor or permitted assignee pursuant to this Section 10.8.

Section 10.9 Severability. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application thereof to any Person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision, and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application thereof, in any other jurisdiction.

Section 10.10 Execution of Agreement. This Agreement may be executed in one or more counterparts, each of which will be deemed to be an original copy of this Agreement and all of which, when taken together, will be deemed to constitute one and the same agreement. The exchange of copies of this Agreement and of signature pages by facsimile or e-mail 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. Signatures of the Parties transmitted by facsimile or e-mail shall be deemed to be their original signatures for all purposes.

Section 10.11 Specific Performance. Subject to Section 8.2, the Parties hereto, including IEG (solely with respect to Section 7.9), acknowledge and agree that irreparable harm for which monetary damages would not be an adequate remedy would occur in the event of a breach of any of the terms or provisions of this Agreement related to effecting the Closing or Section 2.7(a) and (d) (Transferred Contracts; Other Assets), Section 2.8(a) (Trading Contracts), Section 2.9 (Exchange Traded Transactions), Section 2.10 (Mirror Transactions), Section 2.11 (ISO Contracts), Section 7.3 (Filings; Commercially Reasonable Efforts to Close), Section 7.6 (Transition Plans), Section 7.7 (Confidentiality) and Section 7.9 (Non-Competition). Accordingly, the Parties hereto, including IEG, agree that, in addition to other remedies, each of the Parties shall be entitled to specific performance without the necessity of proving the inadequacy of monetary damages as a remedy and to obtain injunctive relief against any such breaches or threatened breaches of this Agreement.

Section 10.12 Disclosures. Prior to the Closing Date, the Seller may, at its option, supplement or amend the Schedules with items that are not material in order to avoid any misunderstanding; provided, however, that any such inclusion, or any references to dollar amounts, shall not be deemed to effectuate an acknowledgment or representation that such items

are material, to establish any standard of materiality, or to define further the meaning of such terms for purposes of this Agreement. Other than with respect to supplements and amendments made in accordance with Section 2.10(b), (i) in the event that the Purchaser reasonably believes that the changes to the Schedules resulting from such supplements and amendments, considered collectively, will cause a closing condition set forth in Section 5.1 to fail to be satisfied, the Purchaser shall have the right to terminate this Agreement upon fifteen (15) Business Days notice from the date of such relevant supplement or amendment pursuant to Article VIII, and (ii) if the Purchaser does not exercise its right pursuant to clause (i) above, any supplement or amendment made pursuant this Section 10.12 shall not diminish, limit or waive the Seller’s indemnification obligations under this Agreement.
