(b) except with a 30-day prior written notice to the Issuer, the Servicer and, so long as the Notes are outstanding, the Trustee, change its name, identity, legal entity type or jurisdiction of organization; provided, however, that neither the Issuer nor the Trustee has any right or power to prohibit a change in the Parent’s name, identity, legal entity type or jurisdiction of organization; provided, further, if any change in the Parent’s name, identity, legal entity type or jurisdiction of organization would make any financing or continuation statement or notice of lien filed in connection with this Purchase and Sale Agreement seriously misleading within the meaning of applicable provisions of the UCC, the Parent hereby authorizes each of the Issuer and the Trustee to file such amendments as may be required to preserve and protect the Issuer’s title and interest and the Trustee’s security interest in and to the Purchased Assets and proceeds thereof and the collateral, if any, related thereto; it is understood that, during the term of this Purchase and Sale Agreement, the Parent shall maintain its jurisdiction of organization in the United States;

(d) terminate (or agree with any counterparty to any termination thereof by mutual agreement) any Principal Document in whole or in part;

(e) take any action to waive, repeal, amend, vary, supplement or otherwise modify the Issuer Organizational Documents in a manner that would adversely affect the rights, privileges or preferences of any Noteholder;

(j) take any action adverse to the Issuer under the Residual License Agreement except as contemplated by the Transaction Documents.

Section 6.3 Reporting. The Parent shall, unless the Issuer shall otherwise consent in writing:

(a) subject to applicable confidentiality restrictions, make available such other information as the Issuer or the Trustee may, from time to time, reasonably request with respect to (i) the Purchased Assets or (ii) the condition or operations, financial or otherwise, of it that is reasonably likely to impact or affect the performance of its obligations hereunder or its compliance with the terms, provisions and conditions of this Purchase and Sale Agreement;

(b) promptly (but in no event more than five Business Days following its receipt thereof) provide to the Issuer and the Servicer copies of any Notices between the Parent and any other party to any Principal Document regarding any such Principal Document, including copies of Notices it receives pursuant to Section 12.4 of the Inspire License Agreement, but shall not be required to do so to the extent that any such Notice does not relate to and could not be expected to affect the Purchased Assets in any material respect;

(c) deliver to the Issuer and the Servicer, with a copy to the Trustee, within 120 days after the end of each fiscal year of the Parent ending after the date hereof, a certificate of a Responsible Officer, stating whether or not, to the best knowledge of such Responsible Officer, any party to any Principal Document is in default in the performance and observance of any of the terms, provisions and conditions of any such Principal Document (without regard to any period of grace or requirement of notice provided thereunder) and, if any such party shall be in default, specifying the nature of all such defaults and the steps the Parent plans or expects to take in relation to any such default thereof of which he or she may have knowledge;

(i) an act or failure to act of any party to any Principal Document or other Person that constitutes or, with the passage of time, would constitute a default thereunder or that gives rise or, with the passage of time, would give rise to the right of any party to exercise any remedies thereunder, including any right to terminate any Principal Document; or

(ii) any actual or overtly threatened termination by Inspire or Pfizer of any Principal Document to which it is party in whole or in part; and

(e) during any period in which the Parent is not subject to Section 13 or 15(d) of the Exchange Act, deliver to the Issuer and the Trustee (i) audited financial statements of the Parent with respect to its most recent fiscal year no later than 120 days after the end of such fiscal year and (ii) unaudited interim financial statements of the Parent with respect to each fiscal quarter (except for fiscal year-end) no later than 45 days after the end of such fiscal quarter, in each case, prepared in accordance with GAAP in all material respects.

Section 6.4 Certain Covenants. The mere occurrence of any termination of the Inspire License Agreement will not in and of itself comprise or demonstrate the occurrence of a breach by the Parent of Section 6.1(c), Section 6.1(d), Section 6.1(e), Section 6.1(f), Section 6.1(m), Section 6.1(q), Section 6.2(a) or Section 6.2(c), and the determination of whether the Parent has breached any of the foregoing provisions will be made without regard to any actual termination of the Inspire License Agreement.

ARTICLE IX

MISCELLANEOUS

Section 9.1 Transfers Intended as Sales. Each of the parties hereto expressly intends and agrees that the sale, transfer, conveyance, assignment, contribution and granting of the Purchased Assets contemplated and effected under this Purchase and Sale Agreement are complete and absolute sales rather than pledges or assignments of only a security interest and shall be given effect as such for all purposes. If, however, notwithstanding the express intent of the parties hereto, such sale, transfer, conveyance, assignment, contribution and granting are deemed to be a secured financing, this Purchase and Sale Agreement is a security agreement and the Parent hereby grants to the Issuer a security interest in all of the Parent’s right, title and interest in, to and under the following, in each case, whether now owned or existing or hereafter acquired or arising, and wherever located: (a) the Purchased Assets; and (b) any and all additions and accessions to any of the foregoing, all substitutions and replacements therefor and all products and proceeds thereof, to secure the performance of all of the Parent’s obligations in connection with such secured financing. The sale, transfer, conveyance, assignment, contribution and granting of the Purchased Assets and the grant of the license under the Residual License Agreement shall be reflected on the Parent’s balance sheet and other financial statements and computer records as a sale of assets and a license to the Issuer consistent with GAAP. The sale, transfer, conveyance, assignment, contribution and granting by the Parent of the Purchased Assets hereunder are and shall be without recourse to, or representation or warranty (express or implied) by, the Parent, except as otherwise specifically provided herein. The limited rights of recourse specified herein against the Parent in connection with the sale, transfer, conveyance, assignment, contribution and granting by the Parent of the Purchased Assets hereunder are intended to provide a remedy for breach of representations and warranties relating to the condition of the assets sold, breach of the covenants in this Purchase and Sale Agreement or for other indemnified amounts (including Indemnified Amounts) set forth in Section 8.1 or Section 9.11, rather than to the collectibility of underlying indebtedness and other payment obligations.

Section 9.2 Specific Performance. Any party may enforce specific performance of this Purchase and Sale Agreement.

Section 9.3 Notices. All Notices shall be in writing and shall be effective (a) upon receipt when sent through the mails, registered or certified mail, return receipt requested, postage prepaid, with such receipt to be effective the date of delivery indicated on the return receipt, (b) upon receipt when sent by an overnight courier, (c) on the date personally delivered to an authorized officer of the party to which sent, (d) on the date transmitted by legible telecopier transmission with a confirmation of receipt or (e) in the case of any report that is of a routine nature, on the date sent by first class mail or overnight courier or transmitted by legible telecopier transmission, in all cases, with a copy emailed to the recipient at the applicable address, addressed to the recipient in accordance with Section 12.5 of the Indenture. A copy of each Notice given hereunder to any party hereto shall also be given to the other party hereto. Each party hereto may, by notice given in accordance herewith to the other party hereto, designate any further or different address to which subsequent Notices shall be sent.

Section 9.4 CHOICE OF LAW. THIS PURCHASE AND SALE AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL SUBSTANTIVE LAWS OF THE STATE OF NEW YORK WITHOUT REFERENCE TO THE RULES THEREOF RELATING TO CONFLICTS OF LAW OTHER THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

Section 9.5 Counterparts. This Purchase and Sale Agreement may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all of such counterparts shall together constitute but one and the same instrument.

Section 9.6 Amendment.

(a) The provisions of this Purchase and Sale Agreement may from time to time be amended, modified, supplemented, restated or waived, if such amendment, modification, supplement, restatement or waiver is in writing and consented to by each of the parties hereto and, so long as the Notes are outstanding, the Trustee pursuant to Section 9.1 or Section 9.2 of the Indenture, as applicable.

(b) No failure or delay on the part of the Issuer, the Parent or the Trustee exercising any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power or right preclude any other or further exercise thereof or the exercise of any other power or right. No notice to or demand on the Issuer or the Parent in any case shall entitle it to any notice or demand in similar or other circumstances. No waiver or approval by the Issuer under this Purchase and Sale Agreement shall, except as may otherwise be stated in such waiver or approval, be applicable to subsequent transactions. No waiver or approval under this Purchase and Sale Agreement shall require any similar or dissimilar waiver or approval thereafter to be granted hereunder.

(c) The Transaction Documents contain a final and complete integration of all prior expressions by the parties hereto and thereto with respect to the subject matter hereof and thereof and shall constitute the entire agreement among the parties hereto and thereto with respect to the subject matter hereof and thereof, superseding all prior oral or written understandings.

Section 9.7 Severability of Provisions. If any one or more of the covenants, agreements, provisions or terms of this Purchase and Sale Agreement shall be for any reason whatsoever held invalid, then such covenants, agreements, provisions or terms shall be deemed severable from the remaining covenants, agreements, provisions or terms of this Purchase and Sale Agreement and shall in no way affect the validity or enforceability of the other covenants, agreements, provisions or terms of this Purchase and Sale Agreement.

Section 9.8 Binding Effect; Assignability; Survival. This Purchase and Sale Agreement shall be binding upon and inure to the benefit of the Issuer, the Parent and the Trustee and their respective successors and permitted assigns. Neither the Parent nor the Issuer may assign any of its rights hereunder or any interest herein without the prior written consent of the other party and, in the case of the Parent, so long as the Notes are outstanding, the Trustee pursuant to Section 9.1 or Section 9.2 of the Indenture, as applicable, except as otherwise herein specifically provided; provided, however, that a Change of Control shall not by itself be deemed an assignment for purposes of this Section 9.8. This Purchase and Sale Agreement shall create and constitute the continuing obligations of the parties hereto in accordance with its terms, and shall remain in full force and effect until such time as the parties hereto shall agree, it being agreed that the parties hereto shall not terminate this Purchase and Sale Agreement at any time prior to payment in full of the Notes. The rights and remedies with respect to (i) any breach of any representation and warranty made by the Parent pursuant to Section 5.1, (ii) the indemnification and payment provisions of Article VIII and (iii) the provisions of Section 9.4, Section 9.10, Section 9.11, Section 9.12, Section 9.13 and Section 9.14 shall be continuing and shall survive any termination of this Purchase and Sale Agreement.

Section 9.9 Acknowledgement and Agreement. The Parent expressly acknowledges and agrees that all of the Issuer’s right, title and interest in, to and under this Purchase and Sale Agreement (including the Issuer’s rights under the Servicing Agreement) and the Residual License Agreement shall be pledged and assigned to the Trustee as collateral by the Issuer pursuant to the Indenture, and the Parent consents to such pledge and assignment. Each of the parties hereto acknowledges and agrees that the Trustee, acting on behalf of the Noteholders, is a third party beneficiary of all of the rights of the Issuer arising hereunder and shall be entitled to exercise the rights of the Issuer to give consents under Section 6.2, to receive materials under Section 6.1(j), Section 6.3(c) and Section 6.3(d) and to enforce the rights of the Issuer set forth in Section 8.1 and Section 9.11. Except as set forth in the preceding sentence with respect to the rights of the Issuer under Section 6.1(j), Section 6.2, Section 6.3(c), Section 6.3(d), Section 8.1 and Section 9.11, each of the parties hereto further acknowledges and agrees that the rights of the Issuer arising hereunder that have been assigned and pledged to the Trustee under the Indenture may be enforced by the Trustee only so long as an Event of Default has occurred and is continuing and the Trustee is exercising remedies under the Indenture, in each case at the direction of Noteholders holding a majority in Outstanding Principal Balance of the Senior Class of Notes. In all other cases, the Issuer shall have the right to give and withhold consents and exercise or refrain from exercising rights and remedies hereunder.

Section 9.10 Cumulative Remedies. The remedies herein provided are cumulative and not exclusive of any remedies provided by law. Without limiting the foregoing, the Parent hereby authorizes the Issuer at any time and from time to time, to the fullest extent permitted by law, to offset any amounts payable by the Issuer to, or for the account of, the Parent against any obligations of the Parent to the Issuer arising in connection with the Transaction Documents (including amounts payable pursuant to Section 8.1) that are then due and payable.

Section 9.11 Costs, Expenses and Taxes. In addition to the obligations of the Parent under Article VIII, the Parent agrees:

(a) to pay to the Issuer on demand all reasonable costs and expenses incurred by the Issuer in connection with the enforcement of this Purchase and Sale Agreement and the other Transaction Documents to be delivered hereunder;

(b) to indemnify the Issuer on an after-tax basis for any stamp and other Taxes and fees payable or determined to be payable in connection with the execution, delivery, filing and recording of this Purchase and Sale Agreement or the other Transaction Documents, and to indemnify each Indemnified Party on an after-tax basis in respect of any liabilities with respect to such Taxes and fees; and

(c) to indemnify the Issuer on an after-tax basis for any U.S. federal, state or local or any foreign income, franchise or other Taxes imposed on income or assets (including any interest, penalties or accountant or counsel fees incurred in connection with such Taxes) asserted against, withheld from or required to be withheld by the Issuer at any time that the Notes are outstanding.

Section 9.12 No Proceedings. The Parent hereby agrees that it will not institute against the Issuer, or join any Person in instituting against the Issuer, any insolvency or similar proceeding (namely, any Voluntary Bankruptcy or Involuntary Bankruptcy) until one year and one day after the date on which the Notes have been paid in full.

Section 9.13 Consent to Jurisdiction.

(a) Any legal action or proceeding with respect to this Purchase and Sale Agreement may be brought in the courts of the State of New York located in the Borough of Manhattan, The City of New York or of the United States federal court sitting in the Borough of Manhattan, The City of New York, and, by execution and delivery of this Purchase and Sale Agreement, each party hereto consents, for itself and in respect of its property, to the non-exclusive jurisdiction of those courts. Each party hereto irrevocably consents to service of process in the manner provided for notices in Section 9.3. Nothing in this Purchase and Sale Agreement shall affect the right of any party hereto to serve process in any other manner permitted by law. Each party hereto irrevocably waives, to the maximum extent permitted by law, any objection, including any objection to the laying of venue or based on the grounds of forum non conveniens, that it may now or hereafter have to the bringing of any action or proceeding in such jurisdiction in respect of this Purchase and Sale Agreement or any document related hereto. Each party hereto waives personal service of any summons, complaint or other process, which may be made by any other means permitted by New York law.

(b) If, for the purpose of obtaining a judgment or order in any court, it is necessary to convert a sum due hereunder from U.S. dollars into another currency, each of the Issuer and the Parent has agreed that the rate of exchange used shall be that at which, in accordance with normal banking procedures, such party could purchase U.S. dollars with such other currency in the Borough of Manhattan, The City of New York on the Business Day preceding the day on which final judgment is given.

(c) The obligation of each of the Issuer and the Parent in respect of any sum payable by it hereunder shall, notwithstanding any judgment or order in a Judgment Currency, be discharged only to the extent that, on the Business Day following receipt thereby of such security of any sum adjudged to be so due in the Judgment Currency, it may in accordance with normal banking procedures purchase U.S. dollars with the Judgment Currency. If the amount of U.S. dollars so purchased is less than the sum originally due to such party in the Judgment Currency (determined in the manner set forth in Section 9.13(b)), each of the Issuer and the Parent agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such party against such loss, and, if the amount of the U.S. dollars so purchased exceeds the sum originally due to such party, such party agrees to remit to the payor, such excess, provided that such party shall have no obligation to remit any such excess as long as the payor shall have failed to pay such party any obligations due and payable pursuant to such judgment, in which case such excess may be applied to such obligations of such party in accordance with the terms of such judgment. The foregoing indemnity shall constitute a separate and independent obligation of the Issuer and the Parent and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid.

Section 9.14 Limited Recourse. The Parent accepts that the enforceability against the Issuer of any obligations of the Issuer hereunder shall be limited to the assets of the Issuer, whether tangible or intangible, real or personal (including the Collateral) and the proceeds thereof. Once all such assets have been realized upon and such assets (and proceeds thereof) have been applied in accordance with Article III of the Indenture, any outstanding obligations of the Issuer to the Parent hereunder shall be extinguished. The Parent further agrees that it shall take no action against any employee, director, officer or administrator of the Issuer in relation to this Purchase and Sale Agreement except in the exercise of its rights to proceed against any employee, director, officer or administrator of the Issuer (a) for intentional and willful fraud or intentional and willful misrepresentations on the part of or by such employee, director, officer or administrator or (b) for the receipt of any distributions or payments to which the Parent or any successor in interest is entitled.

The Table of Contents and headings of the Articles and Sections of this Purchase and Sale Agreement have been inserted for convenience of reference only, are not to be considered a part hereof and shall in no way modify or restrict any of the terms or provisions hereof.
