Section 5.5 Counterparty License Agreement.

(a) The Seller (i) shall perform and comply in all material respects with its duties and obligations under the Counterparty License Agreement, (ii) shall not forgive, release or compromise any amount owed to or becoming owing to it under the Counterparty License Agreement, (iii) shall not, without the prior written consent of the Purchaser, assign (other than in accordance with Section 8.4), amend, modify, supplement, restate, waive, cancel or terminate (or consent to any cancellation or termination of), in whole or in part, the Counterparty License Agreement or any rights constituting or involving or affecting or relating to the Purchased Assets or the right to receive the Royalties, (iv) shall not breach any of the provisions of the Counterparty License Agreement, (v) except pursuant to Section 5.6, shall not enter into any new agreement in respect of the Purchased Assets or MT 400 (solely in respect of the Territory), (vi) shall not waive any obligation of, or grant any consent to, Counterparty under or in respect of MT 400 (in respect of the Territory), the Counterparty License Agreement or the other Purchased Assets and (vii) shall not agree to do any of the foregoing.

(b) The Seller shall not, without the prior written consent of the Purchaser (except as set forth in the last sentence of Section 5.1(c) with respect to the Outstanding Litigation), grant any consent or withhold any consent, exercise or waive any right or option, fail to exercise any right or option or take or fail to take any action in respect of, affecting or relating to the Purchased Assets, MT 400 (in respect of the Territory) or the Counterparty License Agreement (including, for the avoidance of doubt, the conduct of any matters referred to in Section 2.3 of the Counterparty License Agreement) in any manner that would, in each case, reasonably be expected to (i) result in a Material Adverse Change or (ii) cause an event of default under, or breach or termination of, this Purchase and Sale Agreement, any other Transaction Document or the Counterparty License Agreement. Notwithstanding the foregoing, the Parties agree that (x) the Seller and the Purchaser shall consult with each other in advance of the conduct of any negotiations referred to in Section 2.3 of the Counterparty License Agreement and (y) the Seller shall then proceed, in consultation with the Purchaser, to conduct any negotiations with Counterparty pursuant to such Section 2.3, provided, however, that the Seller shall not effect any agreement with respect to the matters referred to in such Section 2.3 without the prior written consent of the Purchaser (it being understood and agreed that the Purchaser shall, in the course of such negotiations, act in good faith and shall not take any position that would cause the Seller to breach its obligations under such Section 2.3).

(c) Promptly after (i) receiving notice from Counterparty (A) terminating the Counterparty License Agreement (in whole or in part), (B) alleging any breach of or default under the Counterparty License Agreement by the Seller or (C) asserting the existence of any facts, circumstances or events that, alone or together with other facts, circumstances or events, could reasonably be expected (with or without the giving of notice or passage of time, or both) to give rise to a breach of or default under the Counterparty License Agreement by the Seller or the right to terminate the Counterparty License Agreement (in whole or in part) by Counterparty or (ii) the Seller otherwise has knowledge of any fact, circumstance or event that, alone or together with other facts, circumstances or events, could reasonably be expected (with or without the giving of notice or passage of time, or both) to give rise to a breach of or default under the Counterparty License Agreement by the Seller or give the right to terminate the Counterparty License Agreement (in whole or in part) by Counterparty, in each case, the Seller shall (A) promptly (and in any event within five Business Days) give a written notice to the Purchaser describing in reasonable detail the relevant breach, default or termination event, including a copy of any written notice received from Counterparty, and, in the case of any breach or default or alleged breach or default by the Seller, describing in reasonable detail any corrective action the Seller proposes to take, and (B) use commercially reasonable efforts to promptly cure such breach or default and shall promptly (and in any event within five Business Days) give written notice to the Purchaser upon curing such breach or default; provided, however, that, if the Seller fails to cure such breach or default, the Purchaser shall, to the extent permitted by the Counterparty License Agreement, be entitled to take any and all actions the Purchaser considers reasonably necessary to promptly cure such breach or default, and the Seller shall reasonably cooperate with the Purchaser for such purpose and reimburse the Purchaser promptly (but in no event later than five Business Days following notice thereof) for all costs and expenses incurred in connection therewith.

(d) Promptly after the Seller obtains knowledge of a breach or default or alleged breach or default under the Counterparty License Agreement by Counterparty or of the existence of any facts, circumstances or events that, alone or together with other facts, circumstances or events, could reasonably be expected (with or without the giving of notice or passage of time, or both) to give rise to a breach or default under the Counterparty License Agreement by Counterparty or the right to terminate the Counterparty License Agreement (in whole or in part) by the Seller, in each case, the Seller shall (i) within five Business Days of obtaining such knowledge, give a written notice to the Purchaser describing in reasonable detail the relevant breach, default or termination event and (ii) if requested by the Purchaser, proceed in consultation with the Purchaser and take such permissible actions (including commencing legal action against Counterparty with legal counsel selected by the Purchaser, such counsel to be reasonably satisfactory to the Seller) to enforce compliance by Counterparty with the relevant provisions of the Counterparty License Agreement and to exercise any or all of the Purchaser’s or the Seller’s rights and remedies, whether under the Counterparty License Agreement or by operation of law, with respect thereto. The Purchaser shall have the right, at its sole expense, to participate in and control, with counsel appointed by it, any meeting, discussion, action, suit or other proceeding relating to any such breach, default or termination event or alleged breach, default or termination event, including any counterclaim, settlement discussions or meetings; provided, that the fees and expenses of the Purchaser’s counsel in connection therewith shall be borne by the Seller if such breach, default or termination event or alleged breach, default or termination event results from, or is caused by, directly or indirectly, a breach or default by the Seller. The Seller shall make reasonably available its relevant records and personnel to the Purchaser in connection with any prosecution or litigation against Counterparty to enforce any of the Purchaser’s or the Seller’s rights under the Counterparty License Agreement, with Purchaser reimbursing Seller for all of its reasonable out-of-pocket costs and expenses incurred in connection therewith. In the event the Purchaser does not exercise its right to control any meeting, discussion, action, suit or other proceeding under this Section 5.5(d), then the Purchaser shall reimburse Seller for all out-of-pocket costs and expenses (including reasonable attorneys fees) incurred by Seller in connection with enforcing the provisions of this Section 5.5(d); provided, that such out-of-pocket costs and expenses (including the fees and expenses of the Seller’s counsel) shall be borne by the Seller if such breach, default or termination event or alleged breach, default or termination event results from, or is primarily caused by, directly or indirectly, a breach or default by the Seller. Notwithstanding anything to the contrary contained in this Article V, nothing herein shall prevent, restrict or limit the Purchaser from directly enforcing Counterparty’s payment obligations in respect of the Purchased Assets with counsel selected by the Purchaser in its sole discretion.

(e) The Seller shall (i) subject to the provisions of the Counterparty License Agreement and any rights of Counterparty thereunder, take such commercially reasonable actions, and prepare, execute, deliver and file any and all agreements, documents and instruments, that are reasonably necessary to diligently preserve and maintain the Intellectual Property Rights, including payment of maintenance fees or annuities, at the sole expense of the Seller, (ii) take commercially reasonable steps to diligently defend (and enforce) the Intellectual Property Rights against infringement or interference by any other Person, and against any claims of invalidity or unenforceability, in any relevant jurisdiction (including by bringing any legal action for infringement or defending counterclaim of invalidity or action of a third party for declaratory judgment of non-infringement or non-interference) in the Territory, and (iii) when available in respect of MT 400, obtain patents and any corrections, substitutions, reissues and reexaminations thereof, obtain patent term extensions and any other forms of patent term restoration in any country of the Territory and obtain patent listing in the FDA Electronic Orange Book. The Seller shall not disclaim or abandon, or fail to take any commercially reasonable action necessary to prevent the disclaimer or abandonment of, the Intellectual Property Rights. The Purchaser shall have the right, at its sole expense, to participate in and control, with counsel appointed by it, any meeting, discussion, action, suit or proceeding (including the Outstanding Litigation) involving the infringement, legality, validity or enforceability of the Intellectual Property Rights or the Counterparty License Agreement to the same extent that the Seller has such rights under the Counterparty License Agreement, including any counterclaim, settlement discussions or meetings, and the Seller shall exercise and enforce such rights on its own behalf (and on behalf of the Purchaser) to the fullest extent permitted under the terms of the Counterparty License Agreement; provided, that the Seller’s exercise and enforcement of such rights shall not result in a breach of this Purchase and Sale Agreement or a Material Adverse Change; provided, further, that the fees and expenses of the Purchaser’s counsel in connection therewith shall be borne by the Seller if such infringement, legality, validity or enforceability is caused by the Seller. In the event the Purchaser does not exercise its right to control any meeting, discussion, action, suit or proceeding under this Section 5.5(e), then the Purchaser shall reimburse Seller for all out-of-pocket costs and expenses (including reasonable attorneys fees) incurred by the Seller in connection with enforcement of the provisions of this Section 5.5(e); provided, that such out-of-pocket costs and expenses (including the fees and expenses of the Seller’s counsel) shall be borne by the Seller if such infringement, legality, validity or enforceability is caused by the Seller. For the avoidance of doubt (but subject to the proviso of the immediately preceding sentence), all out-of-pocket costs and expenses relating to the Outstanding Litigation shall be borne by (x) the Seller, to the extent that such costs and expenses accrued prior to the Closing, and (y) the Purchaser, to the extent that such costs and expenses accrued on or after the Closing.

(f) Except in connection with an assignment by the Seller to any other Person with which the Seller may merge or consolidate or to which the Seller may sell all or substantially all of its assets or all of its assets related to MT 400 in accordance with the provisions of Section 8.4, the Seller shall not dispose of, assign or otherwise transfer, or grant, incur or suffer to exist any Lien on the Counterparty License Agreement, the Purchased Assets or any of the Seller’s right, title or interest in and to the Intellectual Property Rights (in whole or in part), without the prior written consent of the Purchaser.

(g) The Seller shall to the extent reasonably practicable make available its records and personnel to the Purchaser in connection with any prosecution of litigation by the Purchaser against Counterparty to enforce any of the Purchaser’s or the Seller’s rights under the Counterparty License Agreement, and provide reasonable assistance and authority to file and bring the litigation, including, if required to bring the litigation, being joined as a party plaintiff. The Purchaser shall reimburse Seller for all out-of-pocket costs and expenses (including reasonable attorneys’ fees) incurred in connection with this Section 5.5(g).

(h) The Seller shall not exercise the Co-Promotion Option without the prior written consent of the Purchaser.

Section 5.6 Termination of the Counterparty License Agreement; Mergers, Consolidations and Asset Sales Involving Counterparty.

(a) Without limiting the provisions of Section 5.5, if Counterparty or the Seller terminates or provides written notice of termination of the Counterparty License Agreement (in whole or in part), or the Counterparty License Agreement is otherwise terminated (in whole or in part), then the Seller shall provide reasonable assistance to and cooperate with the Purchaser, at the Purchaser’s sole discretion, cost and expense (including the Purchaser’s payment of the Seller’s reasonable attorneys’ fees in connection therewith, if any), in such efforts as the Purchaser shall reasonably undertake in connection with the negotiation of a license of the Intellectual Property Rights, which shall include terms no less favorable in the aggregate to the Seller than those contained in the Counterparty License Agreement with respect to obligations and costs imposed on the Seller, disclaimers of the Seller’s liability, intellectual property ownership and control, commercialization diligence and indemnification of the Seller (any such license, a “New Arrangement”). Should the Purchaser identify any New Arrangement, the Seller agrees to negotiate in good faith such New Arrangement that satisfies the foregoing requirements promptly upon the written request of the Purchaser. In the event the Seller enters into a New Arrangement, the Seller agrees to comply in all material respects with the provisions of this Purchase and Sale Agreement in connection with the New Arrangement and references herein to the Purchased Assets and the Counterparty License Agreement shall be deemed to be references to any new purchased asset and any new license agreement, constructed under the New Arrangement, and references to Counterparty shall be deemed to be references to the other party to such new license agreement and that other party’s Affiliates and sublicensees or licensees, as the case may be. Such New Arrangement shall also provide, for no additional consideration from the Purchaser, that (i) the Purchaser shall have the same rights as those acquired under the Counterparty License Agreement pursuant to this Purchase and Sale Agreement and (ii) all payments and other consideration (including any upfront fees) thereunder be made by the other party to such New Arrangement directly to the Purchaser.

(b) If there occurs a merger or consolidation of the Seller, on the one hand, and Counterparty or its Affiliates, on the other hand, a sale of all or substantially all of the Seller’s assets to Counterparty or a sale or assignment of the Counterparty License Agreement or the Intellectual Property Rights by the Seller to Counterparty, and in any such case the Counterparty License Agreement is terminated in connection therewith, the Seller (or its successor) shall pay to the Purchaser royalties on Net Sales of MT 400 in the Territory for the term of the Counterparty License Agreement on the same basis as if the Counterparty License Agreement had continued and the Purchaser’s rights with respect to the Purchased Assets and the covenants of the Seller under this Purchase and Sale Agreement shall continue to apply on the same basis as if the Counterparty License Agreement was in place between the Seller and Counterparty.

Section 5.7 Audits. Beginning on the Closing Date, the Purchaser shall have the exclusive right, at its sole expense (and using an accountant designated by the Purchaser and reasonably satisfactory to the Seller), to inspect and audit Counterparty’s books and records at any time and from time to time, in accordance with Section 7.11 of the Counterparty License Agreement, at its sole discretion for payments that are paid or payable to the Purchaser with respect to Net Sales and Royalties beginning on or after the Royalty Commencement Date. Notwithstanding the foregoing, the Seller shall retain the exclusive right to inspect and audit Counterparty’s books and records at any time and from time to time, in accordance with Section 7.11 of the Counterparty License Agreement, at its sole discretion and its sole expense, for payments that are paid or payable to the Seller pursuant to the Counterparty License Agreement with respect to Net Sales and Royalties attributable to the period prior to the Royalties Commencement Date. The Seller shall not, without the prior written consent of the Purchaser, such consent not to be unreasonably withheld, cause an inspection or audit of Counterparty’s books and records under this Section 5.7 or under Section 7.11 of the Counterparty License Agreement for the period commencing on the Royalty Commencement Date.

Section 5.8 Tax Matters.

(a) Notwithstanding the accounting treatment thereof, for United States federal, state and local tax purposes, the Seller and the Purchaser shall treat the transactions contemplated by the Transaction Documents as a sale for United States federal, state and local tax purposes.

(b) All payments to the Purchaser under this Purchase and Sale Agreement shall be made without any deduction or withholding for or on account of any tax; provided, that, if deduction or withholding of any tax is required from any such payment under this Purchase and Sale Agreement or from any payment under the Counterparty License Agreement by reason of the Seller’s being a party to the Counterparty License Agreement, then the sum payable shall be increased and paid by the Seller as necessary so that, after making all required deductions and withholdings, the Purchaser receives an amount equal to the amount that it would have received had no such deductions or withholdings been made.

(c) The parties hereto agree not to take any position that is inconsistent with the provisions of this Section 5.8 on any tax return or in any audit or other administrative or judicial proceeding unless (i) the other party hereto has consented to such actions or (ii) the party hereto that contemplates taking such an inconsistent position has been advised by nationally recognized tax counsel in writing that there is no “reasonable basis” (within the meaning of Treasury Regulation Section 1.6662-3(b)(3)) for the position specified in this Section 5.8. If there is an inquiry by any Governmental Authority of the Seller or the Purchaser related to this Section 5.8, the parties hereto shall cooperate with each other in responding to such inquiry in a reasonable manner consistent with this Section 5.8.

Section 7.1 Indemnification by the Seller. The Seller agrees to indemnify and hold each of the Purchaser and its Affiliates and any and all of their respective partners, directors, managers, members, officers, employees, agents and controlling persons (each, a “Purchaser Indemnified Party”) harmless from and against, and will pay to each Purchaser Indemnified Party the amount of, any and all Losses (including attorneys fees) awarded against or incurred or suffered by such Purchaser Indemnified Party, whether or not involving a third party claim, demand, action or proceeding, arising out of (i) any breach of any representation, warranty or certification made by the Seller in any of the Transaction Documents to which the Seller is party or certificates given by the Seller to the Purchaser in writing pursuant to this Purchase and Sale Agreement, (ii) any breach of or default under any covenant or agreement by the Seller to the Purchaser pursuant to any Transaction Document to which the Seller is party, (iii) any Excluded Liabilities and Obligations (unless such Excluded Liabilities and Obligations are due to the Purchaser not complying with any confidentiality provisions set forth in this Purchase and Sale Agreement), and (iv) any fees, expenses, costs, liabilities or other amounts incurred or owed by the Seller to any brokers, financial advisors or comparable other Persons retained or employed by it in connection with the transactions contemplated by this Purchase and Sale Agreement; provided, however, that the foregoing shall exclude any indemnification to any Purchaser Indemnified Party to the extent resulting from (A) the bad faith, gross negligence or willful misconduct of such Purchaser Indemnified Party or (B) acts or omissions of the Seller based upon the written instructions from any Purchaser Indemnified Party. Notwithstanding the foregoing, absent Seller’s actual fraud, in no event shall Seller’s indemnification obligations under clause (i) of this Section 7.1 exceed, individually or in the aggregate, an amount equal to the Purchase Price, less all Royalties received by Purchaser, without duplication, under this Agreement prior to and through resolution of the applicable claim.

Section 7.2 Indemnification by the Purchaser. The Purchaser agrees to indemnify and hold each of the Seller and its Affiliates and any and all of their respective partners, directors, managers, members, officers, employees, agents and controlling Persons (each, a “Seller Indemnified Party”) harmless from and against, and will pay to each Seller Indemnified Party the amount of, any and all Losses (including attorneys’ fees) awarded against or incurred or suffered by such Seller Indemnified Party, whether or not involving a third party claim, demand, action or proceeding, arising out of (i) any breach of any representation, warranty or certification made by the Purchaser in any of the Transaction Documents to which the Purchaser is party or certificates given by the Purchaser in writing pursuant to this Purchase and Sale Agreement, (ii) any breach of or default under any covenant or agreement by the Purchaser pursuant to any Transaction Document to which the Purchaser is party and (iii) any fees, expenses, costs, liabilities or other amounts incurred or owed by the Purchaser to any brokers, financial advisors or comparable other Persons retained or employed by it in connection with the transactions contemplated by this Purchase and Sale Agreement; provided, however, that the foregoing shall exclude any indemnification to any Seller Indemnified Party to the extent resulting from (A) the bad faith, gross negligence or willful misconduct of such Seller Indemnified Party or (B) acts or omissions of the Purchaser based upon the written instructions from any Seller Indemnified Party. Notwithstanding the foregoing, absent the Purchaser’s actual fraud, in no event shall the Purchaser’s indemnification obligations under clause (i) of this Section 7.2 exceed, individually or in the aggregate, an amount equal to the Purchase Price, less all payments received by the Seller pursuant to Section 5.4(d) prior to and through resolution of the applicable claim.

Section 7.3 Procedures. If any claim, demand, action or proceeding (including any investigation by any Governmental Authority) shall be brought or alleged against an indemnified party in respect of which indemnity is to be sought against an indemnifying party pursuant to Section 7.1 or Section 7.2, the indemnified party shall, promptly after receipt of notice of the commencement of any such claim, demand, action or proceeding, notify the indemnifying party in writing of the commencement of such claim, demand, action or proceeding, 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 Section 7.1 or Section 7.2 unless, and only to the extent that, the indemnifying party is actually prejudiced by such omission. In case any such action is brought against an indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled, at the indemnifying party’s sole cost and expense, to participate therein and, to the extent that it may wish, 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 Article VII for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and except as provided below. 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 (a) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (b) 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 (c) 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 counsel to the indemnifying party. It is agreed that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable and documented fees and expenses of more than one separate law firm (in addition to local counsel where necessary) for all such indemnified parties. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent (such consent not to be unreasonably withheld), 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 by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party (such consent not to be unreasonably withheld), effect any settlement, compromise or discharge of any claim or 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, compromise or discharge, as the case may be, (i) includes an unconditional written release of such indemnified party, in form and substance reasonably satisfactory to the indemnified party, from all liability on claims that are the subject matter of such claim or proceeding, (ii) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any indemnified party and (iii) does not impose any obligation or restriction on any indemnified party.
