Buyer may assign without the consent of Seller any of its rights or obligations under the Transaction Documents without restriction; provided that, so long as no Event of Default shall have occurred and be continuing, Buyer may not assign any of its rights and obligations under the Transaction Documents to any Competitor without the prior written consent of Seller.

(d)Buyer hereby indemnifies and holds each Seller Indemnified Party harmless from and against any and all Losses incurred or suffered by a Seller Indemnified Party arising out of (i) any breach of any representation or warranty made by Buyer in any of the Transaction Documents or in any certificate delivered pursuant to the Transaction Documents or (ii) any breach of or default under any covenant or agreement by Buyer pursuant to any Transaction Document. Notwithstanding the foregoing, such indemnification by Buyer shall not apply with respect to any Losses to the extent resulting from the gross negligence, willful misconduct or bad faith of any Seller Indemnified Party.
(e)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 and documented 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 has failed to diligently conduct the defense of such Claim, (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; or (iv) the Claim relates to taxes or any criminal or regulatory enforcement Claim. 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 (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding; (ii) provides for the payment by the indemnifying party of money as sole relief for the claimant; and (iii) involves no finding or admission of any violation of Law or the rights of any Person and has no effect on any other claims that have been made against the indemnified person.
(f)The only legal action that may be asserted by or on behalf of any Buyer Indemnified Party or Seller Indemnified Party with respect to any matter arising out of the transactions contemplated by this Agreement or the Transaction Documents shall be an action to enforce or to recover Losses as an indemnification claim pursuant to this Section 8.04. Without limiting the generality of the foregoing, no legal action based upon predecessor or successor liability, contribution, tort, strict liability or any statute, regulation or ordinance may be maintained by or on behalf of Buyer or any Buyer Indemnified Party or Seller or any Seller Indemnified Party, as applicable, with respect to any matter that is the subject of this Section 8.04.
(g)Losses shall be (i) calculated net of actual recoveries received by or on behalf of an 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, any indemnified party may take any action against an indemnifying party to enforce or recover Losses pursuant to the indemnification obligations of the indemnifying party under this Section 8.04 without any requirement to take any action or exhaust any right or remedy against any other Person, provided that the indemnified party agrees that the indemnifying party shall then be subrogated to any and all other rights of the indemnified party to recovery to the extent of such indemnification paid by the indemnifying party (but excluding interest amounts and gross-up or other payments in respect of taxes). If any proceeds, benefits or recoveries are received by or on behalf an indemnified party with respect to Losses after an indemnifying party has made an indemnification payment to an 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 indemnified party shall hold such amounts in trust for the benefit of the indemnifying party and, within three (3) Business Days after receipt thereof, deliver such amounts (net of any applicable withholding tax) to the indemnifying party by wire transfer of immediately available funds as directed by the indemnifying party.
(h)Neither Party shall be obligated to indemnify Seller Indemnified Parties or Buyer Indemnified Parties, as applicable, with respect to any Losses as to which such Party is otherwise entitled to assert any claim for indemnification, pursuant to Section 8.04(a)(i) or Section 8.04(b)(i), as applicable, unless and until the aggregate amount of the Losses of Seller Indemnified Parties or Buyer Indemnified Parties in respect of Section 8.04(a)(i) or Section 8.04(b)(i), as applicable, exceed the Indemnity Threshold Amount; provided, however, that

thereafter the indemnifying party shall indemnify Buyer Indemnified Parties or Seller Indemnified Parties, as applicable, for all amounts including, for the avoidance of doubt, the Indemnity Threshold Amount; provided, further, that such foregoing limitation shall not apply to any Losses suffered by any indemnified party in connection with a Third Party Claim.
(i)Notwithstanding anything in this Agreement to the contrary, Seller shall not have any liability under Section 8.04(a) in excess of the sum of (i) the Closing Amount, (ii) all Investment Payments made by Buyer to Seller, and (iii) the applicable Investment Return Amount; provided that such foregoing limitation shall not apply to any Losses suffered by any Buyer Indemnified Party in connection with a Third Party Claim (other than any Losses to the extent resulting from the gross negligence, willful misconduct or bad faith of any Buyer Indemnified Party). Notwithstanding anything in this Agreement to the contrary, Buyer shall not have any liability under Section 8.04(b) in excess of the amount of Royalty Interest Payments received by Buyer pursuant to this Agreement.
Section 1.05. 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)Seller and Buyer shall treat the transactions contemplated by the Transaction Documents as a sale of the Purchased Assets for all purposes (other than financial accounting purposes), including United States federal, state and local tax purposes.
(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) such inconsistent position is required by applicable Law. 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.
(e)The Parties shall use commercially reasonable efforts to ensure all payments to Buyer under this Agreement are made without any deduction or withholding for or on account of any tax, provided that if deduction or withholding is required from any payment under this Agreement, other than any deduction or withholding
47

in respect of (i) any tax that would not have been imposed (or would have been imposed but at a lower rate) but for any connection of Buyer with the jurisdiction of the applicable taxing authority (other than a connection arising solely from this Agreement or any transaction contemplated hereby); (ii) any tax that would not have been imposed (or would have been imposed but at a lower rate) but for any failure of Buyer to provide any applicable documentation permitting such payments to be made without (or at a reduced rate of) withholding that is reasonably requested by Seller and that Buyer is legally eligible to provide and (iii) any U.S. federal withholding tax (such taxes described in clauses (i) through (iii), “Excluded Taxes,” and all such taxes other than Excluded Taxes, “Indemnified Taxes”), the sum payable shall be increased and paid by Seller or any of its Affiliates as necessary so that after all such deductions and withholdings have been made, Buyer receives an amount equal to the amount it would have received had no such deductions or withholding been made. Seller shall promptly notify Buyer in writing in the event that any deduction or withholding is effected or proposed by Seller or, to the Knowledge of Seller, any Governmental Authority, with respect to any such payments hereunder. On or prior to the Closing Date, Buyer shall deliver to Seller a duly executed Internal Revenue Service Form W-9.
(f)The Parties shall treat any Investment Payments pursuant to Section 2.03(b) and any indemnification payments pursuant to Section 8.04 (except to the extent treated as imputed interest pursuant to Sections 483 or 1274 of the Internal Revenue Code of 1986, as amended or otherwise) as adjustments to the purchase price of the Purchased Assets for all tax purposes to the extent permitted by applicable Law.
(g)Without limitation of Section 8.05(d) and (e), this Agreement is not intended to create a deemed partnership, association or joint venture between Buyer and any counterparty. Each Party agrees not to refer to the other as a “partner,” or the relationship as a “partnership” or “joint venture.”

(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.
