This Agreement shall not constitute an agreement or attempted agreement to transfer, sublease, sublicense or assign any privilege, right or interest in any Purchased Asset or any claim, right or benefit arising thereunder or resulting therefrom, if an attempted assignment thereof without the consent required or necessary of a Third Party would constitute a breach or violation thereof or affect adversely the rights of Buyer thereunder. If a consent of a Third Party which is required in order to assign any interest in a Purchased Asset has not been obtained prior to the date of this Agreement, or if an attempted assignment would be or for some reason is ineffective or would adversely affect the ability of the Company to convey its interest in a Purchased Asset to Buyer as set forth herein, then the Company shall use its best efforts, and Buyer will cooperate with the Company to the extent commercially reasonable, to obtain promptly such authorizations, consents or waivers. Pending such authorization, consent or waiver, the Company shall hold any asset that has not been transferred or assigned for the benefit of Buyer, and the Parties shall cooperate with each other in any reasonable and lawful arrangements designed to provide to Buyer the benefits of use of such asset that it would have obtained had the asset been conveyed to Buyer at the Closing.

ADDITIONAL COVENANTS

5.1 General. In case any further action is necessary to carry out the purposes of this Agreement or any Ancillary Agreement, each of the Parties will take such further action (including the execution and delivery of such further instruments and documents) as the other Party may reasonably request, all at the sole cost and expense of the requesting Party (unless the requesting Party is entitled to indemnification therefor under ARTICLE 7 below). At Buyer’s request, the Company shall, at its own expense, reasonably assist Buyer in Buyer’s efforts to obtain copies of raw data and annotated case report forms that were requested by, but not provided to, Buyer prior to the Closing. With respect to any agreement that was entered into by Company with respect to the Development, clinical trial or other testing of Program Compounds and Products (including services agreements and license agreements) but is not a Purchased Contract because the Company no longer has any right, title or interest in or to such agreement, the Company has or shall provide Buyer, upon the written request of Buyer, with a copy of each such agreement, and Buyer has the right to access and use such agreement and to disclose such agreement or its existence to Regulatory Authorities to the extent that such disclosure is not prohibited by such agreement.

5.2 Confidentiality. The Company agrees not to and to cause its Affiliates not to disclose or use any Confidential Information except as may be required in order to perform their respective obligations under this Agreement or any Ancillary Agreement. In the event that the Company is requested or required pursuant to written or oral question or request for information or documents in any legal proceeding, interrogatory, subpoena, civil investigation demand, or similar process to disclose any Confidential Information, the Company will notify Buyer promptly of the request or requirement so that Buyer may seek an appropriate protective order or waive compliance with the provisions of this Section 5.2. If, in the absence of a protective order or the receipt of a waiver hereunder, the Company is, on the advice of counsel, compelled to disclose any Confidential Information, the Company may disclose such Confidential Information; provided, however, that the Company shall use its reasonable efforts to obtain, at the request of Buyer, an order or other assurance that confidential treatment will be accorded to such portion of the Confidential Information required to be disclosed as Buyer shall designate. The foregoing provisions shall not apply to any Confidential Information that is generally available to the public immediately prior to the time of the Company’s disclosure unless such Confidential Information is so available due to the unauthorized actions of the Company. The Company shall treat and hold as confidential all of the terms and conditions of the transactions contemplated by this Agreement and the other Ancillary Agreements; provided, however, that the Company may disclose such information to its legal counsel, accountants, or other advisors on an as-needed basis so long as any such Person is bound by a confidentiality obligation with respect thereto similar to the obligation set forth in this Section 5.2. With respect to any Person that has received or receives Confidential Information from the Company or

pursuant to its relationship with the Company and has obligations of confidentiality, nondisclosure or non-use with respect thereto pursuant to any agreement that is not a Purchased Contract, the Company shall promptly notify Buyer if it becomes aware of any breach or threatened breach of such obligations and, at Buyer’s request, shall take action to enforce such obligations.

5.3 Diligent Efforts.

Buyer may satisfy such obligation in whole or in part through the activities of its Affiliates, and licensees, sublicensees, assignees and subsequent acquirers of Buyer or any of the Purchased Assets. If the Company in good faith believes that Buyer is not using Diligent Efforts to fulfill any of the Milestone Events, then the Company may provide Buyer with written notice thereof specifying in reasonable detail the reasons for such belief. If such notice is given, Buyer shall have [*] from receipt of such notice to cure such alleged deficiencies. If, after such cure period, the Company reasserts in writing substantially the same deficiencies (a “Diligence Notice”), then Buyer shall designate Representatives, including at least one officer with operating responsibility with respect to the Purchased Assets, to meet with the Company’s Representatives within [*] from the date of such Diligence Notice to address in good faith the Company’s belief that Buyer is not using Diligent Efforts and any steps that can be taken to cure any alleged breach of the obligation to use Diligent Efforts. If the participating parties fail to resolve these issues within [*] after such Diligence Notice, then the Company and Buyer shall have the right to initiate an alternative dispute resolution (“ADR”) proceeding in accordance with Section 9.8(b).

(b) If Buyer (together with its Affiliates, licensees, sublicensees, assignees and subsequent acquirers) is no longer engaging in and does not have any plans to engage in the activities required to achieve the Milestone Events (which activities may include pursuing potential licensees, sublicensees, assignees and subsequent acquirers), then Buyer shall send prompt written notice thereof to the Company.

(c) Failure of Buyer to fulfill or perform its obligation to use Diligent Efforts shall not subject such party to any Liability to the extent such failure is caused or occasioned by acts of God, acts of terrorism, fire, explosion, flood, drought, war, riot, sabotage, embargo, strikes or other labor disputes (which strikes or disputes need not be settled), compliance with any order, regulation, or request of government, or by any other event or circumstance of like character to the foregoing beyond the reasonable control and without the fault or negligence of such party (a “Force Majeure Event”), provided such party uses commercially reasonable efforts to remove such Force Majeure Event, gives the Company prompt notice of the existence of such Force Majeure Event and as promptly as reasonably practicable resumes the Diligent Efforts after the Force Majeure Event is alleviated.

(d) Notwithstanding anything to the contrary in this Agreement, Buyer may provide written notice to the Company of Buyer’s intent to discontinue Development and/or commercialization of any Product including through its Affiliates, licensees, sublicensees, assignees and subsequent acquirers (a “Product Discontinuation”) in which case the obligations of Buyer under Sections 5.3(a) to 5.3(c) and Sections 5.3(e) to 5.3(f) shall terminate immediately upon issuance of such notice. In the event that there is a Product Discontinuation and Buyer intends to revert to SK (its Affiliates or their respective successors or assigns) all rights granted by SK to Buyer pursuant to the SK License, Buyer will promptly provide notice of such intended reversion and the proposed timing of such reversion to the Company and will, at the subsequent written request of the Company that is received by Buyer within the proposed timing of such reversion provided by Buyer, use commercially reasonable efforts to assign the SK License to the Company or its nominee, at no additional expense to Buyer.

(e) Information Sharing. For so long as one or more Milestone Payments remains unpaid and still potentially payable, Buyer shall provide the Company with a copy of each report required pursuant to the SK License as it exists on the Closing Date and such other reports as provided to SK (its Affiliates or their respective successors or assigns) from time to time.

Such audits may be conducted during normal business hours at the headquarter offices of Buyer upon reasonable prior written notice to such party. Buyer shall include, in any relevant agreement with its Affiliates, licensees, and sublicensees that have the right to sell Products, such audit rights in favor of the Company. The Company shall bear the full cost of such audit unless such audit discloses that Sales Milestone Payments or Royalty Payments have been underpaid for the applicable period by [*] or more, in which case, Buyer shall bear the full cost of such audit and all subsequent audits. Buyer shall as promptly as reasonably practicable remit any underpayment of Sales Milestone Payments and Royalty Payments in accordance with Section 2.6, together with interest at a rate of (i) the thirty (30) day U.S. Dollar LIBOR rate effective for the date that payment was due, as published by The Wall Street Journal, U.S. Internet Edition at ▇▇▇.▇▇▇.▇▇▇ under the Market Data Center tab, on the date such payment was due, plus an additional [*], or (ii) the maximum rate permitted by applicable Laws, whichever is less, calculated on the number of days such payment is delinquent.

7.3 Survival and Time Limitations.

(a) All representations and warranties of the Parties in this Agreement, in any Ancillary Agreement, or in any other certificate or document delivered pursuant to this Agreement or Ancillary Agreement will survive the Closing and shall expire on the date that is eighteen (18) months after the Closing Date, except that (i) the representations and warranties in [*] (collectively, the “Excluded Representations”) shall survive without any time limitation and (ii) the representations and warranties in [*] (collectively, the “Special Representations”) shall expire on the [*] anniversary of the date [*] (the applicable expiration date for any representation or warranty is referred to as the “Expiration Date”); provided, however, that if, at any time prior to the applicable Expiration Date, any Buyer Indemnitee or Company Indemnitee (as the case may be) delivers to the Company or Buyer (as the case may be) a written notice alleging the existence of an inaccuracy in or a breach of any of such representations and warranties or the existence of any events, facts or circumstances that may give rise to the right of such Buyer Indemnitee or Company Indemnitee (as the case may be) to assert a claim under this ARTICLE 7, and asserting a claim for recovery under this ARTICLE 7 based on such alleged inaccuracy, breach, events, facts or circumstances, then the claim asserted in such written notice shall survive such Expiration Date until such time as such claim is fully and finally resolved.

(c) The right to indemnification of each Party, including payment of any Losses, will not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) by such Party at any time.

7.4 Limitations on Indemnification.

(a) Subject to the other limitations contained in this Agreement, with respect to the matters described in [*], the Company will have no Liability with respect to such matters until Buyer Indemnitees have suffered aggregate Losses by reason of all such breaches in excess of [*] U.S. Dollars ($[*]) (the “Threshold”), after which point the Company will be obligated to indemnify Buyer Indemnitees from and against all Losses above the Threshold; provided, that the foregoing limitations shall not apply in respect of any Losses relating to [*] or [*].

(b) Except with respect to [*] or [*], in no event shall the Company’s aggregate Liability (whether satisfied from the Escrow Fund, set-off against the Contingent Payments or payment directly by the Company) for indemnification pursuant to [*] exceed: (i) with respect to [*], other than with respect to [*], an aggregate amount equal to the sum of [*] plus [*] that [*]; (ii) with respect to [*], an aggregate amount equal to the sum of [*] plus [*] that [*]; and (iii) with respect to [*], including [*] and [*], the sum of [*] plus [*] that [*] (the applicable amount under clauses “(i),” “(ii)” or “(iii),” the “Cap”).

(c) Except with respect to [*] or [*], in no event shall Buyer’s aggregate Liability for indemnification with respect to [*] exceed [*].

(d) The Buyer Indemnitees shall be entitled to, and shall seek payment of, indemnification obligations pursuant to this ARTICLE 7: (i) with respect to [*] (except for [*] or [*]) first by making a claim against the Escrow Fund, and after the Escrow Fund has been exhausted (or is subject to then pending claims that, in the aggregate, equal or exceed the amount held thereunder), then by [*], (ii) with respect to [*], by making a claim against the Escrow Fund or [*], or, after such time as the Escrow Fund has been exhausted, by [*], and (iii) with respect to [*], by [*], by [*], or by [*] (in all cases subject to the limits above).

(e) In no event shall the Company or its Affiliates have any Liability to indemnify any Buyer Indemnitee for [*] (except to the extent such Buyer Indemnitee is liable for such damages and losses to a third party).

7.5 Third-Party Claims.

(a) If a third party initiates a Proceeding (a “Third-Party Claim”) against any Person (the “Indemnified Party”) with respect to any matter that the Indemnified Party shall be entitled to make a claim for indemnification against the other Party (the “Indemnifying Party”) under this ARTICLE 7, then the Indemnified Party must promptly notify the Indemnifying Party in writing of the existence of such Third-Party Claim and must deliver copies of any documents served on the Indemnified Party with respect to the Third-Party Claim; provided, however, that any failure on the part of an Indemnified Party to so notify an Indemnifying Party shall not limit any of the obligations of the Indemnifying Party under this ARTICLE 7, except to the extent such failure materially prejudices the defense of such Proceeding.

(b) Upon receipt of the notice described in Section 7.5(a), the Indemnifying Party will have the right to defend the Indemnified Party against the Third-Party Claim with counsel reasonably satisfactory to the Indemnified Party, provided, that (i) the Indemnifying Party provides the Indemnified Party with evidence reasonably acceptable to the Indemnified Party that the Indemnifying Party will have the financial resources to defend against the Third-Party Claim and fulfill its indemnification obligations hereunder, and unconditionally confirms in writing that it will satisfy its indemnification obligations under this ARTICLE 7 with respect to such Third-Party Claim, (ii) the Third-Party Claim involves only money damages and does not seek an injunction or other equitable relief, (iii) settlement of, or an adverse judgment with respect to, the Third-Party Claim is not, [*], likely to (A) [*], or (B) [*], (iv) the Indemnifying Party conducts the defense of the Third-Party Claim actively and diligently, and (v) the amount sought by the third party does not exceed the applicable Cap; and provided, further, that, notwithstanding anything in this Agreement to the contrary, Buyer shall have the right to control the defense of any Third Party Claim involving or pertaining to any Purchased Intellectual Property or any Program Compound or Product. The Indemnifying Party will keep the Indemnified Party apprised of all material developments, including settlement offers, with respect to the Third-Party Claim and permit the Indemnified Party to participate in the defense of the Third-Party Claim. So long as the Indemnifying Party is conducting the defense of the Third-Party Claim in accordance with this Section 7.5(b), the Indemnifying Party will not be responsible for any attorneys’ fees or other expenses incurred by the Indemnified Party regarding the Third-Party Claim. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, enter into any settlement agreement with respect to a Third-Party Claim that does not provide for a full release of the Indemnified Party.

(c) In the event that any of the conditions under Section 7.5(b) is or becomes unsatisfied, (i) the Indemnified Party may defend against, and consent to the entry of any judgment on or enter into any settlement with respect to, the Third-Party Claim in any manner it may reasonably deem appropriate, (ii) the Indemnifying Party will reimburse the Indemnified Party promptly and periodically

for the costs of defending against the Third-Party Claim (including reasonable attorneys’ fees and expenses for one counsel), and (iii) the Indemnifying Parties will remain responsible for any Losses the Indemnified Party may suffer resulting from, arising out of or caused by the Third-Party Claim to the extent provided in this ARTICLE 7.

7.6 Other Indemnification Matters. All indemnification payments under this ARTICLE 7 will be deemed adjustments to the Purchase Price.

7.7 Exclusive Remedy. Each Party acknowledges and agrees that, except [*], from and after the Closing, the indemnification provisions of this ARTICLE 7 shall be the sole and exclusive remedies for money damages for breaches of representations and warranties, the failure or non-performance by any Party hereto of any covenants or agreements, or any other claim in connection with the transactions contemplated by this Agreement, except in the case of fraud or intentional misrepresentation; provided, however, notwithstanding the foregoing, nothing in this ARTICLE 7 shall be deemed to prohibit or limit any Party’s right at any time on or after the Closing Date to seek injunctive or equitable relief for the failure of any Party to perform any covenant or agreement contained in this Agreement or any documents executed or delivered pursuant hereto. No Buyer Indemnitee (other than Buyer) is entitled to assert any indemnification claim under this Agreement unless Buyer consents to the assertion of such claim.

7.8 Mitigation. (a) All Losses shall be calculated after giving effect to any proceeds that have been recovered by Buyer or any of its Affiliates from a Third Party or under any policy of insurance, after deducting from such proceeds any costs of asserting a claim for such amounts and any increase in the future in any insurance premium due to such claim. Buyer agrees to use its commercially reasonable efforts to seek to recover any amounts available under any insurance policy or from any Third Party against whom Buyer has a valid and commercially reasonable claim, provided, however, that Buyer shall in no event be required to initiate any Proceeding to pursue such claims or otherwise take actions that could be commercially harmful to any business interest of any Buyer Indemnitee. The Buyer Indemnitees shall take, and shall cause their respective Affiliates to take, all reasonable steps to mitigate and otherwise minimize their Losses to the extent commercially reasonably upon and after becoming aware of any event which would reasonably be expected to give rise to any Losses.

7.9 Procedure for Direct Claims. In the event that any Indemnified Party believes that it is entitled or may become entitled, to claim indemnification, compensation or reimbursement under this ARTICLE 7, such Indemnified Party shall notify the Indemnifying Party in writing (the “Direct Claim Notice”). The Direct Claim Notice shall include a non-binding estimate of the amount of Losses suffered, incurred or paid or to be suffered, incurred or paid by such Indemnified Party and contain a description in reasonable detail of the facts and circumstances supporting such Indemnified Party’s claim. The Parties hereby agree to resolve any matters set forth in a Direct Claim Notice in accordance with the procedures set forth in the Escrow Agreement.

TAX MATTERS

8.1 Transfer Taxes. All transfer, documentary, sales, use, stamp, registration, value added and other such Taxes and fees (including any penalties and interest) imposed in connection with this Agreement and the Ancillary Agreements (“Transfer Taxes”) will be borne and paid when due [*] by Buyer and the Company, and the Buyer will prepare or cause to be prepared and cause to be timely filed all necessary Tax Returns and other documentation with respect to all such Transfer Taxes; provided, however, that if and to the extent any Transfer Taxes are payable as a result of [*] or [*], [*] shall [*] such Transfer Taxes.

9.8 Governing Law; Dispute Resolution.

(a) This Agreement shall be governed by and construed in accordance with the domestic Laws of the State of New York without giving effect to any choice or conflict of Law provision or rule (whether of the State of New York or any other jurisdiction) that would cause the application of the Laws of any other jurisdiction other than the State of New York. Subject to Section 9.8(b), each of the Parties and Parent irrevocably consents to the exclusive jurisdiction and venue of the federal and state courts located in the State of New York, in connection with any matter based upon or arising out of this Agreement or the transactions contemplated hereby and agrees that process may be served upon it in any manner authorized by the laws of the State of New York for such Persons and waives and covenants not to assert or plead any objection which it might otherwise have to such jurisdiction and such process.

(b) The Parties and Parent expressly acknowledge and agree any dispute, controversy, or claim arising out of or in any way relating to this Agreement, including but not limited to any valid amendments or modifications to this Agreement and any related agreements, whether sounding in contract, tort, or any other theory of liability, including but not limited to alleged fraud or misrepresentation and claims based upon a federal or state statute (collectively, a “Dispute”), shall be resolved exclusively in accordance with the provisions of this Section 9.8(b) and Schedule 9.8(b). In the event of any Dispute between the parties, prior to any party commencing arbitration as set forth on Schedule 9.8(b), the complaining party shall first promptly provide a written explanation of the Dispute and designate a representative for purposes of Dispute resolution, delivered in accordance with the notice provisions of Section 9.7. Upon receipt of the complaining party’s Dispute notice, the receiving party shall respond in writing to state its position with respect to the Dispute and designate its own representative for purposes of Dispute resolution. The parties’ respective representatives shall then

promptly meet in person or speak telephonically in a good-faith attempt to resolve the Dispute. If, within [*] of the date of the complaining party’s notice of Dispute, (i) the parties are unable to resolve the Dispute via discussions between their designated representatives, or (ii) the parties’ designated representatives do not engage in good-faith discussions for any reason, then either party may commence arbitration proceedings in accordance with Schedule 9.8(b). Notwithstanding anything herein to the contrary, nothing in this Section 9.8(b) shall preclude either Party from seeking interim or provisional relief, including a temporary restraining order, preliminary injunction or other interim equitable relief concerning a dispute, if necessary to protect the interests of such Party pursuant to Section 9.10 below. This Section shall be specifically enforceable.

9.9 Amendments and Waivers. No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by Buyer and the Company. No waiver by any Party of any provision of this Agreement or any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, shall be valid unless the same shall be in writing and signed by the Party making such waiver nor shall such waiver be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence.

9.10 Injunctive Relief. The Parties hereby agree that in the event of breach of this Agreement damages would be difficult, if not impossible, to ascertain, that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that, in addition to and without limiting any other remedy or right it may have, Buyer and the Company shall be entitled to seek an injunction or other equitable relief in any court of competent jurisdiction, without any necessity of proving damages or any requirement for the posting of a bond or other security, enjoining any such breach and enforcing specifically the terms and provisions. The Parties hereby waive any and all defenses they may have on the ground of lack of jurisdiction or competence of the court to grant such an injunction or other equitable relief.

9.11 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction.

9.12 Expenses. Except as otherwise provided herein, each Party will bear its own costs and expenses (including legal fees and expenses) incurred in connection with this Agreement and the transactions contemplated hereby.

9.13 Construction. The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement. Any reference to any Law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise.
