(a)           To the extent that the Transfer or the Assumption requires any Governmental Approvals, the Parties shall use reasonable best efforts to obtain any such Governmental Approvals.  If and to the extent that the Transfer or the Assumption would be a violation of applicable laws or require any Governmental Approval in connection with the Separation or the Distribution, then, unless PDL shall otherwise determine, the Transfer to or Assumption by Facet of such Facet Assets or Facet Liabilities, as the case may be, shall be automatically deemed deferred and any such purported Transfer or the Assumption shall be null and void until such time as all legal impediments are removed and/or each of such Governmental Approval has been obtained.

(b)           The Parties shall use reasonable best efforts to obtain any Consents required in connection with the transactions contemplated by this Agreement.  Notwithstanding the foregoing, no Party shall be obligated to pay any consideration therefor to any Third Party from whom any such Consent, substitution or amendment is requested (unless such Party is fully reimbursed by the requesting Party).

2.4          Deferred Transfers/Assumptions.

(a)           If the Transfer of any Facet Asset or Assumption intended to be Transferred and assumed hereunder is not consummated prior to or at the Effective Time, whether as a result of the provisions of Section 2.3 or for any other reason, then PDL shall thereafter hold such Facet Asset for the use and benefit of Facet if permitted by Law.

12

(b)           If and when the Consents and/or Governmental Approvals, or any other impediments to Transfer or Assumption, the absence of which caused the deferral of Transfer of any Facet Asset or Assumption pursuant to Section 2.3 or otherwise, are obtained or removed (as appropriate), the Transfer of the applicable Facet Asset or Assumption shall be effected in accordance with the terms of this Agreement and/or the applicable Ancillary Agreement.

(c)           With respect to any Facet Asset retained by PDL due to the deferral of the Transfer of such Facet Asset, PDL shall take such actions with respect to such Facet Asset as may be reasonably requested by Facet.

(d)           If the Parties are unable to obtain, or to cause to be obtained, any such required Governmental Approvals, Consents, release, substitution or amendment pursuant to Section 2.3 or otherwise, PDL shall (i) continue to be bound by such Contract, license or other obligation, which shall not constitute a Liability of PDL (unless not permitted by Law or the terms thereof), and (ii) as agent or subcontractor for Facet, pay, perform and discharge fully all the obligations or other Facet Liabilities thereunder after the Effective Time; provided, however, that PDL shall not be obligated to extend, renew or otherwise cause such Contract, license or other obligation to remain in effect beyond the term in effect as of the Effective Time.  Facet shall fully indemnify PDL and its Affiliates, officers, directors, employees, agents and hold each of them harmless against any and all obligations or Facet Liabilities arising in connection therewith and also for any actions requested by Facet pursuant to Section 2.4(c), provided, however, that Facet shall have no obligation to indemnify PDL with respect to any matter to the extent that PDL has engaged in any violation of Law or fraud in connection therewith.  PDL shall, without further consideration, promptly pay and remit, or cause to be promptly paid or remitted, to Facet, all money, rights and other consideration received by it or any of its Subsidiaries in respect of such performance on behalf of Facet (unless any such consideration is an Excluded Asset of PDL pursuant to this Agreement).  If and when any such Governmental Approval, Consent, release, substitution or amendment shall be obtained or such agreement, lease, license or other rights or obligations shall otherwise become assignable or capable of novation, PDL shall promptly assign, or cause to be assigned, all rights, obligations and other Facet Liabilities thereunder of PDL’s to Facet without payment of any further consideration and Facet, without the payment of any further consideration, shall assume such rights and obligations and other Facet Liabilities.

2.5          Calculation, Adjustment and Payment of Selected Liabilities.

(a)           “PDL Consolidated Balance Sheet” shall mean the unaudited consolidated balance sheet of PDL, dated as of the day immediately preceding the Distribution Date, prepared on a basis consistent with the basis on which the unaudited consolidated balance sheet included in PDL’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2008 and filed with the Securities and Exchange Commission on November 12, 2008 was prepared.

13

(b)           “Selected Liabilities” shall mean certain current liabilities that are both recorded on the PDL Consolidated Balance Sheet in accordance with U.S. generally accepted accounting principals (“GAAP”) and unpaid as of the Effective Time, in the following categories: accrued vacation, accrued preclinical and clinical trial expenses, personnel-related restructuring accruals and accrued post-employment benefits.  For clarity, the Selected Liabilities shall be recorded on the Opening Facet Balance Sheet.

(c)           Payment of Current Liabilities.  PDL shall under the terms of each respective Contract remit payment to vendors for all current liabilities that are both recorded on the PDL Consolidated Balance Sheet in accordance with GAAP and unpaid as of the Effective Time, with the exception of (i) the Selected Liabilities and (ii) any deferred revenue and debt accounts that are recorded on the Opening Facet Balance Sheet.  Facet shall remit payment for the Selected Liabilities to the payees identified by PDL under the terms of each respective Contract.

(d)           Initial Selected Liabilities Statement and Post-Closing Cash.  Facet shall provide PDL in writing with its estimate for the amount of the Selected Liabilities within fifteen (15) business days after the Effective Time (the “Selected Liabilities Statement”).  PDL shall have ten (10) business days following the receipt of the Selected Liabilities Statement to review and analyze Facet’s calculation of the amount set forth in the Selected Liabilities Statement (the “Post-Closing Cash”) and PDL shall then pay to Facet any undisputed part of the Post-Closing Cash.  If PDL does not agree with Facet’s calculation of the Post-Closing Cash, the parties shall work in good faith to resolve the disagreement.  After resolution of such disagreement, any payments owing either to Facet as a result of such adjustment shall be made within five (5) business days after the agreement of the parties.

2.6           Termination of Agreements.  Except with respect to this Agreement and the Ancillary Agreements (and agreements expressly contemplated herein or therein to survive by their terms), the Parties hereby terminate any and all written or oral agreements, arrangements, commitments or understandings, between or among them, effective as of the Effective Time; and each Party shall, at the reasonable request of the other Party, take, or cause to be taken, such other actions as may be necessary to effect the foregoing.

2.7           Disclaimer of Representations and Warranties.  THE PARTIES UNDERSTAND AND AGREE THAT, EXCEPT AS EXPRESSLY SET FORTH HEREIN OR IN ANY ANCILLARY AGREEMENT, NO PARTY TO THIS AGREEMENT, ANY ANCILLARY AGREEMENT OR ANY OTHER AGREEMENT OR DOCUMENT CONTEMPLATED BY THIS AGREEMENT HEREBY OR THEREBY, IS REPRESENTING OR WARRANTING IN ANY WAY AS TO THE FACET ASSETS, FACET BUSINESS OR FACET LIABILITIES CONTRIBUTED, TRANSFERRED, DISTRIBUTED OR ASSUMED AS CONTEMPLATED HEREBY OR THEREBY, AS TO ANY CONSENTS OR GOVERNMENTAL APPROVALS REQUIRED IN CONNECTION HEREWITH OR THEREWITH, AS TO THE VALUE OR FREEDOM FROM ANY SECURITY INTERESTS OF, OR ANY OTHER MATTER CONCERNING, ANY FACET ASSETS, FACET BUSINESS OR FACET

14

LIABILITIES OR AS TO THE ABSENCE OF ANY DEFENSES OR RIGHT OF SETOFF OR FREEDOM FROM COUNTERCLAIM WITH RESPECT TO ANY CLAIM, INCLUDING ANY ACCOUNTS RECEIVABLE, OF ANY PARTY, OR AS TO THE LEGAL SUFFICIENCY OF ANY CONTRIBUTION, DISTRIBUTION, ASSIGNMENT, DOCUMENT, CERTIFICATE OR INSTRUMENT DELIVERED HEREUNDER TO CONVEY TITLE TO ANY FACET ASSET OR THING OF VALUE UPON THE EXECUTION, DELIVERY AND FILING HEREOF OR THEREOF.  EXCEPT AS MAY EXPRESSLY BE SET FORTH HEREIN OR IN ANY ANCILLARY AGREEMENT, ALL SUCH FACET ASSETS ARE BEING TRANSFERRED ON AN “AS IS,” “WHERE IS” BASIS AND SO LONG AS THE TRANSFEROR IS IN COMPLIANCE WITH THE TERMS OF THIS AGREEMENT RELATING TO THE TRANSFER, THE TRANSFEREE SHALL BEAR THE ECONOMIC AND LEGAL RISKS THAT (I) ANY CONVEYANCE SHALL PROVE TO BE INSUFFICIENT TO VEST IN THE TRANSFEREE GOOD AND MARKETABLE TITLE, FREE AND CLEAR OF ANY SECURITY INTEREST, AND (II) ANY NECESSARY CONSENTS OR GOVERNMENTAL APPROVALS ARE NOT OBTAINED OR THAT THE REQUIREMENTS OF LAWS, CONTRACTS, OR JUDGMENTS ARE NOT COMPLIED WITH.

(i)            PDL and Facet shall cooperate to change the name, effective on or prior to the Distribution Date, of any entity that is part of (i) Facet and any of its Affiliates so that the words “PDL,” or derivations thereof are not included in any such name, and (ii) PDL and its Affiliates so that the word “Facet” or derivations thereof are not included in any such name.  Notwithstanding the foregoing, Facet may continue to operate PDL BioPharma France S.A.S. under that name during the period in which Facet

3.3           Conditions to Distribution.  Subject to Section 3.2, the following are conditions to the consummation of Distribution.  The conditions are for the sole benefit of PDL and shall not give rise to or create any duty on the part of PDL or the Board of Directors of PDL to waive or not waive any such condition:

(a)           The Form 10 shall have been declared effective by the SEC, with no stop order in effect with respect thereto;

(b)           All permits, registrations and consents required under the securities or blue sky laws of the states or other political subdivisions of the United States or of other foreign jurisdictions in connection with the Separation and the Distribution shall have been obtained and be in full force and effect;

Article IV

Insurance

4.1                                 Policies and Rights Included Within the Facet Assets.  Without limiting the generality of the definition of the Facet Assets, the Facet Assets shall include (a) the Facet Policies and (b) any and all rights of an insured Party or its Affiliates under each of the PDL Pre-Distribution Policies, to the extent allowable under such Policies, including rights of indemnity and the right to be defended by or at the expense of the insurer, with respect to all injuries, losses, Liabilities, damages and expenses incurred or claimed to have been incurred prior to the Effective Time by any Party or any of its Affiliates in connection with the Facet Business (provided PDL shall have equal rights with respect to indemnity and the right to be defended to the extent practical and appropriate) and which injuries, losses, liabilities, damages and expenses may arise out of insured or insurable occurrences or events under one or more of the PDL Pre-Distribution Policies; provided, however, that nothing in this Section 4.1 shall be deemed to constitute (or to reflect) the assignment of the PDL Pre-Distribution Policies, or any of them, to Facet.

4.2                                 Post-Effective Time Claims.

(a)                                  If, subsequent to the Effective Time, any Person shall assert a claim against Facet or its Affiliates with respect to any injury, loss, Liability, damage or expense incurred or claimed to have been incurred prior to the Effective Time, including claims related to the Facet Business, or in connection with the Distribution, and such injury, loss, Liability, damage or expense may have or has arisen out of insured or insurable occurrences, claims or events under one or more of the PDL Pre-Distribution Policies, PDL shall at the time such claim is asserted (except to the extent inconsistent with Section 4.1 and to the extent allowable under the PDL Pre-Distribution Policies) be deemed to assign, without need of further documentation, to Facet or its Affiliates, any and all rights of an insured party under the applicable PDL Pre-Distribution Policy with respect to such asserted claim, including rights of indemnity and the right to be defended

18

by or at the expense of the insurer; provided, however, that nothing in this Section 4.2 shall be deemed to constitute (or to reflect) the assignment of the PDL Pre-Distribution Policies, or any of them, to Facet.

(b)                                 In the event that any PDL Pre-Distribution Policy does not allow such assignment of a claim to Facet or its Affiliates, at Facet’s sole option, cost and expense, claims for coverage of insured Facet Liabilities shall be tendered by PDL as necessary to invoke the benefit of the PDL Pre-Distribution Policies.  If such insurers do not promptly acknowledge insurance coverage in connection with such insured Facet Liabilities, then, with respect to such insured Facet Liabilities, Facet, on an as-incurred basis (i) shall advance all amounts expended by PDL, incurred at the request of Facet, for or with respect to such insured Facet Liabilities, including all costs and expenses in connection with the defense and settlement and in satisfaction of any judgment incurred, and amounts sufficient to cover any Liabilities required to be paid by PDL or its Subsidiaries, and (ii) shall pay all costs incurred in connection with pursuing and recovering Insurance Proceeds with respect to the insured Facet Liabilities, but only to the extent so requested by Facet, which shall be entitled to direct such recovery efforts.  Any payments made to PDL or its Subsidiaries by Facet or the Facet Subsidiaries on account of such insured Facet Liabilities shall be deemed to be advances pursuant to this Section 4.2.  Facet and the Facet Subsidiaries shall have the right to recover any advances made pursuant to Section 4.3 from PDL and its Subsidiaries, and PDL and its Subsidiaries shall have the obligation promptly to reimburse Facet and the Facet Subsidiaries for such advances, solely from the Insurance Proceeds of the PDL Pre-Distribution Policies that cover such insured Facet Liabilities and that are received by PDL or its Subsidiaries.  PDL and its Subsidiaries (i) shall, at all times until paid to Facet, hold Insurance Proceeds received for or with respect to insured Facet Liabilities in trust for the benefit of Facet; and (ii) shall promptly remit such Insurance Proceeds to Facet.

4.3                                 PDL Policies.  PDL shall, to the extent that the PDL Policies cover the Facet Liabilities, after discussion with Facet, either (a) maintain the PDL Policies, (b) buy replacement insurance, or (c) purchase an extended reporting period endorsement for the PDL Policies.  In each of (a), (b) and (c), such coverage shall be at the expense of Facet and be of a type and with a limit and terms and conditions similar to those in force under the PDL Policies as of the Effective Time and shall be maintained for a minimum of six (6) years after the Effective Time.

(c)                                  Nothing contained in Section 5.1(a) and Section 5.1(b) shall impair or otherwise affect any right of any Party to enforce this Agreement or any Ancillary Agreement.  In addition, nothing contained in Section 5.1(a) and Section 5.1(b) shall release any Party from:

(i)                                     any Liability assumed by, or transferred, or assigned or allocated to, a Party or its respective Affiliates pursuant to or contemplated by this Agreement or any Ancillary Agreement;

(ii)                                  any Liability provided in or resulting from any other Contract or understanding that is entered into after the Effective Time between one Party (and/or a member of such Party’s Affiliates), on the one hand, and the other Party (and/or a member of such Party’s Affiliates), on the other hand; and

(iii)                               any Liability that the Parties may have with respect to indemnification or contribution pursuant to this Agreement or otherwise for claims brought against the Parties by a Third Party, which Liability shall be governed by the provisions of this Article V and, if applicable, the appropriate provisions of the Ancillary Agreements.

(d)                                 Each Party shall not, and shall not permit any of its Subsidiaries to, make any claim or demand, or commence any Action asserting any claim or demand, including any claim of contribution or indemnification, against the other Party or any member of the other Party’s Affiliates, or any other Person released pursuant to Section 5.1(a) and Section 5.1(b), with respect to any and all Liabilities released pursuant to Section 5.1(a) and Section 5.1(b).  If a Party breaches this Section 5.1(d), such breaching Party shall be liable for all related expenses, including court costs, attorneys’ fees, and all other legal expenses of the other Party.

20

(e)                                  It is the intent of each Party, by virtue of the provisions of this Section 5.1, to provide for a full and complete release and discharge of all Liabilities existing or arising from all acts and events occurring or failing to occur or alleged to have occurred or to have failed to occur and all conditions existing or alleged to have existed on or before the Effective Time, whether known or unknown, between one Party (and/or any Affiliate of such Party) and the other Party (and/or a member of such other Party) (including any contractual agreements or arrangements existing or alleged to exist between or among any such members on or before the Effective Time), except as otherwise set forth in this Section 5.1.

(f)                                    If any Person associated with a Party (including any director, officer or employee of a Party) initiates an Action with respect to claims released by this Section 5.1, the Party with which such Person is associated shall indemnify the other Party against such Action in accordance with the provisions set forth in this Article V.

(g)                                 At any time, at the request of a Party, each Party shall, and to the extent practicable, cause each other Person on whose behalf it released Liabilities pursuant to this Section 5.1, to execute and deliver releases reflecting the provisions hereof.

5.2                                 Indemnification by Facet.  Except as otherwise provided in this Agreement or any Ancillary Agreement, following the Effective Time, Facet shall indemnify, defend and hold harmless PDL and its Affiliates and all Persons who at any time prior to the Effective Time were directors, officers, agents or employees of PDL or any of its Affiliates (in each case, in their respective capacities as such), in each case, together with their respective heirs, executors, administrators, successors and assigns (collectively, the “PDL Indemnitees”), from and against any and all Liabilities and related losses of the PDL Indemnitees relating to, arising out of or resulting from any of the following:

(a)                                  The failure of Facet, and its Affiliates or any other Person to pay, perform or otherwise promptly discharge after the Effective Time any Facet Liabilities in accordance with their respective terms;

(b)                                 The Facet Liabilities (including any subsequently identified Facet Liabilities under Section 2.2(e));

(d)                                 Any breach by Facet of this Agreement or any of the Ancillary Agreements.

5.3                                 Indemnification by PDL.  Except as otherwise provided in this Agreement or any Ancillary Agreement, following the Effective Time, PDL shall indemnify, defend and hold harmless Facet, and its Affiliates and all Persons who are directors, officers, agents or employees of Facet or any of its Affiliates (in each case, in their respective

21

capacities as such), in each case, together with their respective heirs, executors, administrators, successors and assigns (collectively, the “Facet Indemnitees”), from and against any and all Liabilities and related losses of the Facet Indemnitees relating to, arising out of or resulting from any of the following items:

(a)                                  The failure of PDL, its Affiliates or any other Person to pay, perform or otherwise promptly discharge after the Effective Time any Excluded Liabilities;

(c)                                  Any breach by PDL of this Agreement or any of the Ancillary Agreements.

5.4                                 Reduction for Insurance Proceeds and Other Recoveries.

(a)                                  The amount that any Party is required to provide indemnification (the “Indemnifying Party”) to or on behalf of the Party entitled to such indemnification (the “Indemnitee”) pursuant to this Article V, shall be reduced (retroactively or prospectively) by Insurance Proceeds or other amounts actually recovered from Third Parties on behalf of such Indemnitee in respect of the Liability or related loss.  If an Indemnitee receives a payment as required by this Agreement from an Indemnifying Party in respect of any Liability or related loss (an “Indemnity Payment”) and subsequently receives Insurance Proceeds in respect of such Liability or related loss, then such Indemnitee shall hold such Insurance Proceeds in trust for the benefit of the Indemnifying Party (or Indemnifying Parties) and shall pay to the Indemnifying Party, as promptly as practicable after receipt, a sum equal to the amount of such Insurance Proceeds received, up to the aggregate amount of any payments received from the Indemnifying Party pursuant to this Agreement in respect of such indemnifiable loss of such Insurance Proceeds.

(b)                                 An insurer who would otherwise be obligated to pay any claim shall not be relieved of the responsibility with respect thereto or, solely by virtue of the indemnification provisions hereof, have any subrogation rights with respect thereto, it being expressly understood and agreed that no insurer or any other Third Party shall be entitled to a “windfall” (i.e., a benefit they would not be entitled to receive in the absence of the indemnification provisions) by virtue of the indemnification provisions hereof.  Notwithstanding the foregoing, each Party shall be required to use reasonable best efforts to collect or recover any available Insurance Proceeds.

5.5                                 Procedures For Indemnification of Third-Party Claims.

(a)                                  If an Indemnitee shall receive notice or otherwise learn of the assertion by a Third Party (including any Governmental entity) of any claim or of the commencement by any such Person of any Action (collectively, a “Third-Party Claim”) with respect to which an Indemnifying Party may be obligated to provide indemnification to such Indemnitee, such Indemnitee shall give such Indemnifying Party and each Party to this Agreement, written notice thereof as soon as reasonably practicable, but no later

22

than thirty (30) days after becoming aware of such Third-Party Claim.  Any such notice shall describe the Third-Party Claim in reasonable detail.  If any Party shall receive notice or otherwise learn of the assertion of a Third-Party Claim which may reasonably be determined to be a Liability of the Parties, such Party shall give the other Party to this Agreement written notice thereof within thirty (30) days after becoming aware of such Third-Party Claim.  Any such notice shall describe the Third-Party Claim in reasonable detail.  Notwithstanding the foregoing, the failure of any Indemnitee or other Party to give notice as provided in this Section 5.5(a) shall not relieve the related Indemnifying Party of its obligations under this Article V, except to the extent that such Indemnifying Party is actually prejudiced by such failure to give notice.

(b)                                 An Indemnifying Party shall be entitled to participate in the defense of any Third-Party Claim, at such Indemnifying Party’s own expense and by such Indemnifying Party’s own counsel; provided that if the defendants in any such claim include both the Indemnifying Party and one or more Indemnitees and in such Indemnitees’ reasonable judgment a conflict of interest between such Indemnitees and such Indemnifying Party exists in respect of such claim, such Indemnitees shall have the right to employ separate counsel and in that event the reasonable fees and expenses of such separate counsel (but not more than one separate counsel reasonably satisfactory to the Indemnifying Party) shall be paid by such Indemnifying Party.  Within thirty (30) days after the receipt of notice from an Indemnitee in accordance with Section 5.5(a) (or sooner, if the nature of such Third-Party Claim so requires), the Indemnifying Party shall notify the Indemnitee of its election whether the Indemnifying Party will assume responsibility for defending such Third-Party Claim.  After notice from an Indemnifying Party to an Indemnitee of its election to assume the defense of a Third-Party Claim, such Indemnitee shall have the right to employ separate counsel and to participate in (but not control) the defense, compromise, or settlement thereof, but the fees and expenses of such counsel shall be the expense of such Indemnitee.

(c)                                  With respect to any Third-Party Claim, the Indemnifying Party and Indemnitees agree, and shall cause their respective counsel (if applicable), to cooperate fully (in a manner that will preserve all attorney-client privilege or other privileges) to mitigate any such claim and minimize the defense costs associated therewith.

(d)                                 If an Indemnifying Party fails to assume the defense of a Third-Party Claim within thirty (30) days after receipt of written notice of such claim, the Indemnitee will, upon delivering notice to such effect to the Indemnifying Party, have the right to undertake the defense, compromise or settlement of such Third-Party Claim on behalf of and for the account of the Indemnifying Party subject to the limitations as set forth in this Section 5.5; provided, however, that such Third-Party Claim shall not be compromised or settled without the written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, delayed or conditioned.  If the Indemnitee assumes the defense of any Third-Party Claim, it shall keep the Indemnifying Party reasonably informed of the progress of any such defense, compromise or settlement.  The Indemnifying Party shall reimburse all such costs and expenses of the Indemnitee in the event it is ultimately determined that the Indemnifying Party is obligated to indemnify the Indemnitee with respect to such Third-Party Claim.  In no event shall an Indemnifying

Party be liable for any settlement effected without its consent, which consent will not be unreasonably withheld, delayed or conditioned.

(a)                                  Any claim on account of a Liability which does not result from a Third-Party Claim shall be asserted by written notice given by the Indemnitee to the related Indemnifying Party.  Such Indemnifying Party shall have a period of thirty (30) days after the receipt of such notice within which to respond thereto.  If such Indemnifying Party does not respond within such sixty (60) day period, such Indemnifying Party shall be deemed to have accepted responsibility to make payment.  If such Indemnifying Party rejects such claim in whole or in part, such Indemnitee shall be free to pursue such remedies as may be available to such party as contemplated by this Agreement and the Ancillary Agreements.

(b)                                 In the event of payment by or on behalf of any Indemnifying Party to any Indemnitee in connection with any Third-Party Claim, such Indemnifying Party shall be subrogated to and shall stand in the place of such Indemnitee as to any events or circumstances in respect of which such Indemnitee may have any right, defense or claim relating to such Third-Party Claim against any claimant or plaintiff asserting such Third-Party Claim or against any other person.  Such Indemnitee shall cooperate with such Indemnifying Party in a reasonable manner, and at the cost and expense (including allocated costs of in-house counsel and other in-house personnel) of such Indemnifying Party, in prosecuting any subrogated right, defense or claim.

(c)                                  In the event of an Action in which the Indemnifying Party is not a named defendant, if the Indemnifying Party shall so request, the Parties shall endeavor to substitute the Indemnifying Party for the named defendant, and add the Indemnifying Party as a named defendant if at all practicable.  If such substitution or addition cannot be achieved for any reason or is not requested, the named defendant shall allow the Indemnifying Party to manage the Action as set forth in this section and subject to Section 5.5 with respect to Liabilities, the Indemnifying Party shall fully indemnify the named defendant against all costs of defending the Action (including court costs, sanctions imposed by a court, attorneys’ fees, experts’ fees and all other external expenses, and the allocated costs of in- house counsel and other in-house personnel), the costs of any judgment or settlement, and the cost of any interest or penalties relating to any judgment or settlement.

5.7                                 Survival of Indemnities.  The rights and obligations of each Party and their respective Indemnitees under this Article V shall survive the sale or other transfer by any Party or its Affiliates of any assets or businesses or the assignment by it of any and all Liabilities.

27

(b)                                 With respect to Facet Books and Records (including e-mails and other electronic correspondence not readily available in hard copy) that relate to both the Facet Business and the PDL Business (the “Combined Books and Records”), (i) the Parties shall use good faith efforts to divide as soon as practicable but no later than six (6) months following the Distribution Date such Combined Books and Records into the books and records which solely relate to PDL or the conduct of the PDL Business and those that relate solely to Facet and the Facet Business, as the case may be, up to the Effective Time, as appropriate, and (ii) to the extent such Combined Books and Records are not so divided, each Party shall keep and maintain copies of such Combined Books and Records as reasonably appropriate under the circumstances, subject to applicable confidentiality provisions hereof and of any Ancillary Agreement.

8.2                                 Access to Information.  Except as otherwise provided in any Ancillary Agreement, after the Distribution Date, each Party shall provide the other Party and such other Party’s authorized accountants, counsel and other designated representatives reasonable access and duplicating rights during normal business hours to all records, books, contracts, instruments, computer data and other data and Information relating to pre-Distribution operations of the Facet Business or PDL Business, as applicable, or within such Party’s possession or control or such other Information reasonably necessary for the preparation, review or auditing for spin-out financials for such other Party (including using reasonable best efforts to give access to Persons or firms possessing Information) insofar as such access is reasonably required by such other Party for the conduct of the Facet Business or PDL Business, as applicable, subject to appropriate restrictions for classified or privileged information.

8.3                                 Production of Witnesses.  At all times after the Effective Time, each of Facet and PDL shall use reasonable best efforts to make available to the other, upon prior written request, its and its Subsidiaries’ officers, directors, employees and agents as witnesses to the extent that such Persons may reasonably be required in connection with any Action.

8.4                                 Privileged Matters.  To allocate the interests of each Party with respect to privileged information, the Parties agree as follows:

(a)                                  PDL shall be entitled, in perpetuity, to control the assertion or waiver of all privileges in connection with privileged information which relates solely to the PDL Business, whether or not the privileged information is in the possession of or under the control of PDL or Facet.  PDL shall also be entitled, in perpetuity, to control the assertion or waiver of all privileges in connection with privileged information that relates solely to the subject matter of any claims constituting Liabilities of PDL and its Affiliates and all Persons who at any time prior to or as of the Effective Time were directors, officers, agents or employees of PDL or any of its Affiliates (in each case, in their respective capacities as such), in each case, together with their respective heirs, executors, administrators, successors and assigns, now pending or which may be asserted in the future, in any lawsuits or other Actions initiated against or by PDL, whether or not the privileged information is in the possession of or under the control of PDL or Facet.

28

(b)           Facet shall be entitled, in perpetuity, to control the assertion or waiver of all privileges in connection with privileged information which relates solely to the Facet Business, whether or not the privileged information is in the possession of or under the control of PDL or Facet.  Facet shall also be entitled, in perpetuity, to control the assertion or waiver of all privileges in connection with privileged information which relates solely to the subject matter of any claims constituting Facet Liabilities, now pending or which may be asserted in the future, in any lawsuits or other Actions initiated against or by Facet, whether or not the privileged information is in the possession of Facet or under the control of PDL or Facet.

(c)           PDL and Facet agree that they shall have a shared privilege, with equal right to assert or waive, subject to the restrictions of this Section 8.4, with respect to all privileges not allocated pursuant to the terms of Sections 8.4(a) and (b).  All privileges relating to any claims, proceedings, litigation, disputes or other matters which involve both PDL and Facet in respect of which PDL and Facet retain any responsibility or liability under this Agreement shall be subject to a shared privilege.

(d)           No Party may waive any privilege which could be asserted under any applicable law, if the other Party has a shared privilege, without the consent of the other Party, except to the extent reasonably required in connection with any litigation with Third Parties or as provided in Section 8.4(e).  Such consent shall be in writing, or shall be deemed to be granted unless written objection is made within twenty (20) days after notice upon the other Party requesting such consent.

(e)           In the event of any litigation or dispute between the Parties and any of its Affiliates, either Party may waive a privilege in which the other Party has a shared privilege, without obtaining the consent of the other Party, provided that such waiver of a shared privilege shall be effective only as to the use of Information with respect to the litigation or dispute between the Parties and any of its Affiliates, and shall not operate as a waiver of the shared privilege with respect to Third Parties.

(f)            If a dispute arises between the Parties regarding whether a privilege should be waived to protect or advance the interest of either Party, each Party agrees that it shall negotiate in good faith, shall endeavor to minimize any prejudice to the rights of the other Party, and shall not unreasonably withhold consent to any request for waiver by the other Party.  Each Party specifically agrees that it will not withhold consent to waiver for any purpose except to protect its own legitimate interests.

(g)           Upon receipt by any Party of any subpoena, discovery or other request which arguably calls for the production or disclosure of Information subject to a shared privilege or as to which the other Party has the sole right hereunder to assert a privilege, or if any Party obtains knowledge that any of its current or former directors, officers, agents or employees has received any subpoena, discovery or other request which arguably calls for the production or disclosure of such privileged information, such Party shall promptly notify the other Party of the existence of the request and shall provide the other Party a reasonable opportunity to review the Information and to assert

29

any rights it may have under this Section 8.4 or otherwise to prevent the production or disclosure of such privileged information.

(h)           The transfer of all Information pursuant to this Agreement is made in reliance on the agreement of PDL and Facet, as set forth in this Section 8.4 and elsewhere in this Agreement, to maintain the confidentiality of privileged information and to assert and maintain applicable privileges.  The access to Information being granted pursuant to Sections 8.1 and 8.2, the agreement to provide witnesses and individuals pursuant to Section 8.3 and the transfer of privileged information between the Parties pursuant to this Agreement shall not be deemed a waiver of any privilege that has been or may be asserted under this Agreement or otherwise.

Article IX

Dispute Resolution

9.1           Disputes and Negotiation.  PDL and Facet recognize that disputes as to certain matters may from time to time arise during the effectiveness of this Agreement and the Ancillary Agreements which relate to either Party’s rights and obligations hereunder or thereunder.  It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising under this Agreement and the Ancillary Agreements in an expedient manner by mutual cooperation and without resort to litigation.  To accomplish this objective, the Parties agree to follow the procedures set forth in this Article IX if and when a dispute arises under this Agreement or the Ancillary Agreements.  In the event of a dispute between the Parties, a designated representative of each of PDL and Facet will meet as reasonably requested by either Party to review any such dispute.  If the disagreement is not resolved by the designated representatives by mutual agreement within thirty (30) days after a meeting to discuss the disagreement, either Party may at any time thereafter provide the other Party written notice specifying the terms of such disagreement in reasonable detail.  Upon receipt of such notice, the chief executive officers of PDL and Facet shall meet at a mutually agreed upon time and location for the purpose of resolving such disagreement.  The chief executive officers of PDL and Facet will discuss such disagreement and/or negotiate for a period of up to sixty (60) days in an effort to resolve such disagreement or negotiate an acceptable interpretation or revision of the applicable portion of this Agreement or the Ancillary Agreements mutually agreeable to both Parties, without the necessity of formal procedures relating thereto.  During the course of such negotiations, the Parties will reasonably cooperate and provide information that is not materially confidential in order that each of the Parties may be fully informed with respect to the issues in dispute.  The institution of a formal proceeding, including arbitration under Section 9.2, to resolve the disagreement may occur by written notice to the other Party only after the earlier of: (i) the chief executive officers of PDL and Facet mutually agreeing that resolution of the disagreement through continued negotiation is not likely to occur; or (ii) the expiration of the sixty (60) day negotiation period.

9.2           Dispute Resolution and Arbitration.  Except as provided in the Non-Exclusive Cross-License Agreement for any disputes concerning Intellectual Property,

30

disputes arising out of, relating to or in connection with this Agreement or the Ancillary Agreements, or in relations between the parties with respect to the subject matter hereof, for any reason or under any circumstances, will be finally settled by a single arbitrator in a binding arbitration in accordance with the Judicial Arbitration and Mediation Services (“JAMS”) Comprehensive Arbitration Rules and Procedures (the “JAMS Rules”).  Upon receipt of written notice by one Party to the other of the existence of a dispute, the Parties shall, within thirty (30) days conduct a meeting of one or more senior executives of each Party, with full settlement authority, in an attempt to resolve the dispute.  Each Party shall make available appropriate personnel to meet and confer with the other Party reasonably within the thirty-day period.  Upon the expiration of the thirty-day period, or upon the termination of discussions between the senior executives, either Party may elect arbitration of any dispute by written notice to the other (the “Arbitration Notice”).  The arbitration shall be held in San Francisco, California before one (1) arbitrator from JAMS having substantial experience as a jurist and mediator with significant disputes in the biotechnology and/or pharmaceuticals industry selected by the mutual agreement of the Facet and the PDL; provided, however, that if such parties cannot agree on an arbitrator within thirty (30) days of the Arbitration Notice, either Party may request JAMS select the arbitrator, and JAMS shall select an arbitrator pursuant to the procedure set out by the JAMS rules; provided, however, that the arbitrator selected by JAMS shall be a former judge with at least fifteen (15) years experience addressing as a jurist and/or mediator significant disputes in the biotechnology and/or pharmaceutical industry.  The arbitration shall be administered by JAMS pursuant to its AAA Rules.  Judgment on the arbitration award may be entered in any court having jurisdiction.  The arbitrator may, in the arbitration award, allocate for payment by the non-prevailing party all or part of the costs of the arbitration, including fees of the arbitrator and the reasonable attorneys’ fees and costs incurred by the prevailing party.  This Section shall not preclude the parties from seeking provisional remedies in aid of arbitration from a court of appropriate jurisdiction.  In respect of any actions for injunctive or other equitable relief hereunder, any action or proceeding may be brought against any Party in the state and federal courts located in the county of San Mateo, California and each of the parties consents to the jurisdiction of such courts in any such action or proceeding and waives any objection to venue laid therein.

31

(b)           Without limiting the foregoing, prior to, on and after the Distribution Date, each Party shall cooperate with the other Party, and without any further consideration, but at the expense of the requesting Party, to execute and deliver, or use its reasonable best efforts to cause to be executed and delivered, all instruments, including instruments of conveyance, assignment and transfer, and to make all filings with, and to obtain all consents, approvals or authorizations of, any Governmental entity or any other Person under any permit, license, agreement, indenture or other instrument (including any Consents or Governmental Approvals), and to take all such other actions as such Party may reasonably be requested to take by the other Party from time to time, consistent with the terms of this Agreement and the Ancillary Agreements, in order to effectuate the provisions and purposes of this Agreement and the Ancillary Agreements and the transfers of the Facet Assets and the assignment and assumption of the Facet Liabilities and the other transactions contemplated hereby and thereby.
