Seller has not caused, by any means, the Seller’s Royalty Interest to be subordinated to the rights of any creditor of Licensee or any other Person. In addition, Seller has not caused, and to the Knowledge of the Seller no other Person has caused, the claims and rights of Buyer created by any Transaction Document (i) out of or in connection with the License Agreement and/or (ii) in and to the Assigned Rights and any Collateral, in each case, to be subordinated to any creditor of Licensee or any other Person; provided, however, that the Seller makes no representation as to whether Buyer (or any Person acting on behalf of Buyer) has caused any

such subordination.

(g) The Seller has not:

Seller has not taken any action that would entitle any Person to any commission or broker’s fee in connection with the transactions contemplated by the Transaction Documents.

Section 3.10 Information.

Other than financial and Product sales projections and analyst reports, all written information heretofore or herein supplied by or on behalf of Seller or any of its Subsidiaries to the Buyer is accurate and complete in all material respects, and none of such information, when taken together with all other information furnished, contains any untrue statement of a material fact or omits to state any material fact necessary to make such information not materially misleading in light of the circumstances under which made.

(d) Notwithstanding anything to the contrary contained in this Agreement or any of the other Transaction Documents, the Receiving Party may disclose the Confidential Information of the Disclosing Party, including this Agreement, the other Transaction Documents and the terms and conditions hereof and thereof, to the extent necessary in connection with the enforcement of its rights and remedies hereunder or thereunder or as required to perfect the Receiving Party’s rights hereunder or thereunder; provided that, the Receiving Party shall only disclose that portion of the Confidential Information that its counsel advises that it is legally required to disclose and will exercise commercially reasonable efforts to ensure that confidential treatment will be accorded to that portion of the Confidential Information that is being disclosed, including requesting confidential treatment of information in the Transaction Documents.

(g) Each of Seller and Buyer hereby (i) agree that, notwithstanding the terms thereof, the Confidentiality Agreement is hereby terminated and (ii) acknowledge that this Agreement shall supersede such Confidentiality Agreement with respect to the treatment of Confidential Information by the Parties (including, without limitation, with regard to Confidential Information previously provided pursuant to such Confidentiality Agreement).

Section 8.03 Successors and Assigns.

The provisions of this Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and assigns. Seller shall not be entitled to assign any of its obligations and rights under the Transaction Documents without the prior written consent of Buyer; provided, however, such consent shall not be required in connection with the merger or other consolidation of Seller or the assignment of Seller’s obligations and rights by operation of law, so long as, the Person into which Seller has been merged or consolidated or which has acquired such assets of Seller has delivered evidence, in form and substance reasonably satisfactory to Buyer, to that such Person has assumed all of Seller’s obligations under the Transaction Documents. So long as the assignee agrees to comply with all covenants set forth in the Shire APA Agreement, Buyer may assign without consent of Seller any of its rights and obligations under the Transaction Documents without restriction. Any purported assignment in violation of this Section 8.03 shall be null and void.

Section 8.04 Indemnification.

(a) Seller hereby indemnifies and holds each Buyer Indemnified Party harmless from and against any and all Buyer Indemnifiable Costs incurred prior to the Agreement Termination Date, Lost Profits incurred or suffered by any Buyer Indemnified Party arising out of a Buyer Indemnity Event, and any Refund Requests received from Seller. For the avoidance of doubt, Buyer, for itself and each other Buyer Indemnified Party, agrees and acknowledges that (i) the maximum aggregate of all awards it can receive in respect of any claims from Seller cannot exceed the difference of (A) $** less (B) the aggregate amount of Royalty Interest Payments received by Buyer from Licensee and not returned to Licensee, (ii) absent a Buyer Indemnity Event, no claim may be asserted by a Buyer Indemnified Party for Lost Profits or Buyer Indemnifiable Costs, and (iii) Lost Profits and Buyer Indemnifiable Costs shall not include and shall be determined without regard for the following (unless resulting from or attributable to a Buyer Indemnity Event): (A) economic risks related to the financial success or performance of the Product or Compound, including, but not limited to, any failures by Licensee in the development and launch of a successful Product or Compound or general economic success of Licensee’s business, (B) the Use of the Product by Licensee or any Third Party, (C) regulatory, medical or clinical risks generally affecting participants in Licensee’s industry, (D) Third Party Claims or judgments that arise out of or in connection with (A), (B), or (C) above, (E) Third Party claims to Third Party Patent Rights to the extent not resulting from a breach of a covenant by Seller hereunder or as a consequence of facts or circumstances in effect as of the Closing Date which facts or circumstances constitute a

breach of a representation or warranty by Seller hereunder, or (F) general economic conditions ((A) through (F) being referred to as the “Assumption of Risk Losses”).

(b) Buyer hereby indemnifies and holds each Seller Indemnified Party harmless from and against any and all Seller Indemnifiable Costs incurred or suffered by a Seller Indemnified Party arising out of a Seller Indemnity Event. For the avoidance of doubt, Seller, for itself and each other Seller Indemnified Party, agrees and acknowledges that (i) absent a Seller Indemnity Event, no claim may be asserted by a Seller Indemnified Party for Seller Indemnifiable Costs, and (ii) Seller Indemnifiable Costs shall not include and shall be determined without regard for: (A) economic risks related to the financial success or performance of the Product or Compound, including, but not limited to, any failures by Licensee in the development and launch of a successful Product or Compound or general economic success of Licensee’s business, (B) the Use of the Product by Licensee or any Third Party, (C) regulatory, medical or clinical risks generally affecting participants in Licensee’s industry, (D) Third Party Claims or judgments that arise out of or in connection with (A), (B), or (C) above, (E) Third Party claims to Third Party Patent Rights to the extent not resulting from a breach of a covenant by Buyer hereunder or as a consequence of facts or circumstances in effect as of the Closing Date which facts or circumstances constitute a breach of a representation or warranty by Buyer hereunder, or (F) general economic conditions.

(c) If any a Claim shall be brought or alleged against an indemnified party in respect of which indemnity is to be sought against an indemnifying party pursuant to the preceding paragraphs, the indemnified party shall, promptly after receipt of notice of the commencement of any such Claim, notify the indemnifying party in writing of the commencement of such Claim, enclosing a copy of all papers served, if any; provided, that the omission to so notify such indemnifying party will not relieve the indemnifying party from any liability that it may have to any indemnified party under the foregoing provisions of this Section 8.04 unless, and only to the extent that, such omission results in the forfeiture of, or has a material adverse effect on the exercise or prosecution of, substantive rights or defenses by the indemnifying party. In case any such Claim is brought against an indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section 8.04 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, an indemnified party shall have the right to retain its own counsel, but the reasonable fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the indemnifying party has assumed the defense of such proceeding and has failed within a reasonable time to retain counsel reasonably

satisfactory to such indemnified party or (iii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interests between them based on the advice of such counsel. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) The only legal actions that may be asserted by or on behalf of any Buyer Indemnified Party with respect to any matter arising out of the transactions contemplated by this Agreement and/or the Transaction Documents shall be an action to enforce or to recover Buyer Indemnifiable Costs and Lost Profits as an indemnification claim pursuant to this Section 8.04, the exercise of Buyer’s rights under the Security Agreement and the right of Buyer to seek specific performance of Seller’s obligations under this Agreement. Without limiting the generality of the foregoing, no legal action based upon predecessor or successor liability, contribution, tort, strict liability or any statute, equity, regulation or ordinance may be maintained by or on behalf of Buyer or any Buyer Indemnified Party with respect to any matter that is the subject of this Section 8.04.

(e) The only legal actions that may be asserted by or on behalf of any Seller Indemnified Party with respect to any matter arising out of the transactions contemplated by this Agreement and/or the Transaction Documents shall be an action to enforce or to recover Seller Indemnifiable Costs as an indemnification claim pursuant to this Section 8.04, the right of the Seller to indemnification for expenses under this Section 8.04 hereof and the right of Seller to seek specific performance of Buyer’s obligations under this Agreement. Without limiting the generality of the foregoing, no legal action based upon predecessor or successor liability, contribution, tort, strict liability or any statute, equity, regulation or ordinance may be maintained by or on behalf of Seller or any Seller Indemnified Party with respect to any matter that is the subject of this Section 8.04.

(f) Buyer Indemnifiable Costs shall be (i) calculated net of actual recoveries received by or on behalf of Buyer or any Buyer Indemnified Party under insurance policies, risk sharing pools or similar arrangements (net of any actual collection costs and recoveries and deductibles) and (ii) reduced by any proceeds received from third parties, through indemnification, counterclaim or otherwise in compensation for the subject matter of an indemnification claim made hereunder. Notwithstanding the foregoing, Buyer or any Buyer Indemnified Party may take any action against Seller to enforce or recover Buyer Indemnifiable Costs and Lost Profits pursuant to the indemnification obligations of Seller under this Section 8.04 without any requirement to take any action or exhaust any right or

remedy against any other Person, provided that Buyer agrees that Seller shall then be subrogated to any and all other rights of Buyer to recovery to the extent of such indemnification paid by Seller (but excluding interest amounts and withholding tax gross-up payments). If any proceeds, benefits or recoveries are received by or on behalf a Buyer Indemnified Party with respect to Buyer Indemnifiable Costs or Lost Profits after Seller has made an indemnification payment to a Buyer Indemnified Party with respect thereto and receipt of such proceeds, benefits or recoveries prior to such payment would have reduced the amount of such indemnification payment if received prior to such payment, then such Buyer Indemnified Party shall hold such amounts in trust for the benefit of Seller and, within five (5) Business Days after receipt thereof, deliver such amounts (net of any applicable withholding tax) to Seller by wire transfer of immediately available funds as directed by Seller.

(g) Seller Indemnifiable Costs shall be (i) calculated net of actual recoveries received by or on behalf of Seller or any Seller Indemnified Party under insurance policies, risk sharing pools or similar arrangements (net of any actual collection costs and recoveries and deductibles) and (ii) reduced by any proceeds received from third parties, through indemnification, counterclaim or otherwise in compensation for the subject matter of an indemnification claim made hereunder. Notwithstanding the foregoing, Seller or any Seller Indemnified Party may take any action against Buyer to enforce or recover Seller Indemnifiable Costs pursuant to the indemnification obligations of Seller under this Section 8.04 without any requirement to take any action or exhaust any right or remedy against any other Person, provided that Seller agrees that Buyer shall then be subrogated to any and all other rights of Seller to recovery to the extent of such indemnification paid by Buyer (but excluding interest amounts and withholding tax gross-up payments). If any proceeds, benefits or recoveries are received by or on behalf a Seller Indemnified Party with respect to Seller Indemnifiable Costs after Buyer has made an indemnification payment to a Seller Indemnified Party with respect thereto and receipt of such proceeds, benefits or recoveries prior to such payment would have reduced the amount of such indemnification payment if received prior to such payment, then such Seller Indemnified Party shall hold such amounts in trust for the benefit of Buyer and, within five (5) Business Days after receipt thereof, deliver such amounts (net of any applicable withholding tax) to Buyer by wire transfer of immediately available funds as directed by Buyer.

(h) Neither Party shall be obligated to indemnify the Seller Indemnified Parties or the Buyer Indemnified Parties, respectively, with respect to any Indemnifiable Costs as to which such Party is otherwise entitled to assert any claim for indemnification, pursuant to Section 8.04(a) or Section 8.04(b), unless and until the aggregate amount of the Indemnifiable Costs of the Seller Indemnified Parties or the Buyer Indemnified Parties, as the case may be, exceeds the Indemnity Threshold Amount; provided, however, that thereafter the indemnifying Party shall indemnify the Buyer Indemnified Parties or Seller Indemnified Parties, as applicable, for all amounts including, for the avoidance of doubt, the Indemnity Threshold Amount.

Section 8.05 Independent Nature of Relationship; Taxes.

(a) The relationship between Seller, on the one hand, and Buyer, on the other hand, is solely that of assignor and assignee, and neither Buyer, on the one hand, nor Seller, on the other hand, has any fiduciary or other special relationship with the other or any of their respective Affiliates. For the avoidance of doubt, nothing in this Agreement shall be read to create any agency, partnership, association or joint venture of Seller (or any of its Affiliates) and Buyer (or any of its Affiliates) and each Party agrees not to refer to the other as a “partner” or the relationship as a “partnership” or “joint venture” or other kind of entity or legal form.

(b) Except as otherwise contemplated herein, no Party shall at any time obligate the other Party, or impose on such other Party any obligation, in any manner or respect to any Third Party.

(c) For United States federal, state and local tax purposes, Seller and Buyer shall treat the transactions contemplated by the Transaction Documents as a sale.

(d) The Parties hereto agree not to take any position that is inconsistent with the provisions of this Section 8.05 on any tax return or in any audit or other administrative or judicial proceeding unless (i) the other Party to this Agreement has consented to such actions, or (ii) the Party that contemplates taking such an inconsistent position has been advised by nationally recognized tax counsel in writing that it is more likely than not that (x) there is no “reasonable basis” (within the meaning of Treasury Regulation Section 1.6662-3(b)(3)) for the position specified in this Section 8.05 or (y) taking such a position would otherwise subject the Party to penalties under the Internal Revenue Code of 1986, as amended. If a Governmental Authority conducts an inquiry of Seller or Buyer related to this Section 8.05, the Parties hereto shall cooperate with each other in responding to such inquiry in a reasonable manner consistent with this Section 8.05.

Section 8.06 Entire Agreement.

This Agreement, together with the Exhibits and Schedules hereto (which are incorporated herein by reference), and the other Transaction Documents constitute the entire agreement between the Parties with respect to the subject matter hereof and supersede all prior agreements (including the Confidentiality Agreement), understandings and negotiations, both written and oral, between the Parties with respect to the subject matter of this Agreement. Neither this Agreement nor any provision hereof (other than Section 8.03), is intended to confer upon any Person other than the Parties any rights or remedies hereunder.

Section 8.07 Amendments; No Waivers.

(a) This Agreement or any term or provision hereof may not be amended, changed or modified except with the written consent of both Parties. No waiver of any right hereunder shall be effective unless such waiver is signed in writing by the Party against whom such waiver is sought to be enforced.

(b) No failure or delay by either 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.

(c) No waiver or approval hereunder shall, except as may otherwise be stated in such waiver or approval, be applicable to subsequent transactions. No waiver or approval hereunder shall require any similar or dissimilar waiver or approval thereafter to be granted hereunder. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by applicable Law.

Section 8.08 Interpretation.

When a reference is made in this Agreement to Articles, Sections, Schedules or Exhibits, such reference shall be to an Article, Section, Schedule or Exhibit to this Agreement unless otherwise indicated. The words “include”, “includes” and “including” when used herein shall be deemed in each case to be followed by the words “without limitation”.

(b) Each Party hereby irrevocably consents to the service of process out of any of the courts referred to in subsection (a) above of this Section 8.13 in any such suit, action or proceeding by the mailing of copies thereof by registered or certified mail, postage prepaid, to it at its address set forth in this Agreement. Each Party hereby irrevocably waives any objection to such service of process and further irrevocably waives and agrees not to plead or claim in any suit, action or proceeding commenced hereunder or under any other Transaction Document that service of process was in any way invalid or ineffective. Nothing herein shall affect the right of a Party to serve process on the other Party in any other manner permitted by law.
