RECITALS

Roche and PDL were originally parties to agreements dated January 31, 1989, as amended (the “1989 Agreements”) pertaining to humanized and chimeric antibodies against the interleukin-2 receptor (“IL-2R”).

Under the 1989 Agreements, PDL exclusively licensed to Roche rights to a humanized antibody now known as Daclizumab (as defined below).

Roche is currently marketing Daclizumab under the trademark Zenapax® for the prevention of acute organ rejection in patients receiving kidney transplants.

In 1999, Roche and PDL replaced the 1989 Agreements with two new agreements (as amended, known separately as the “1999 PDL/Roche Agreement” and the “F. Roche Agreement,” respectively, and collectively as the “1999 Agreements”) which provided PDL with rights to develop and, if successful, promote Daclizumab in autoimmune indications for increased compensation from the 1989 Agreements.

Roche and PDL now desire to replace the 1999 Agreements with this Amended and Restated Worldwide Agreement that (1) reverts to PDL all IL-2R antibody rights licensed to Roche by PDL under the 1999 Agreements, subject to Roche’s continuing exclusive license to market and sell Daclizumab for Transplant Indications in the Roche Territory and develop and commercialize products based [CONFIDENTIAL TREATMENT REQUESTED] that [CONFIDENTIAL TREATMENT REQUESTED] to the [CONFIDENTIAL TREATMENT REQUESTED] of [CONFIDENTIAL TREATMENT REQUESTED]; (2) grants to PDL the sole and exclusive worldwide rights under Roche’s relevant intellectual property to develop, and, if successful, market and sell Daclizumab for Autoimmune Indications and Other Indications; and (3) grants PDL the right to purchase all of Roche’s remaining rights to Daclizumab, subject to Roche’s right to retain its exclusive license from PDL to develop and commercialize products based on [CONFIDENTIAL TREATMENT REQUESTED] that [CONFIDENTIAL TREATMENT REQUESTED] to the [CONFIDENTIAL TREATMENT REQUESTED] of [CONFIDENTIAL TREATMENT REQUESTED].

7.4      Offset for Third Party Licenses.

(a)      Appendix B sets forth the allocation between the parties of the costs associated with each Third Party License entered into prior to the Effective Date.  Such costs include license fees and any other fixed costs associated with the Third Party License as well as any royalties.  After the Effective Date, the parties shall, within [CONFIDENTIAL TREATMENT REQUESTED] of the end of each [CONFIDENTIAL TREATMENT REQUESTED], reimburse each other in accordance with this Section 7.4 to effect the agreed-on sharing of such license fees and other fixed costs.  Both parties hereby acknowledge that [CONFIDENTIAL TREATMENT REQUESTED] has obtained a required license from the [CONFIDENTIAL TREATMENT REQUESTED] to use the [CONFIDENTIAL TREATMENT REQUESTED] in order to carry out the activities anticipated by this Amended and Restated Worldwide Agreement and that [CONFIDENTIAL TREATMENT REQUESTED] has reimbursed [CONFIDENTIAL TREATMENT REQUESTED] under the 1989 Agreements so that the license fees and other fixed costs of the [CONFIDENTIAL TREATMENT REQUESTED] license have been shared [CONFIDENTIAL TREATMENT REQUESTED].

30


(b)      If PDL and Roche agree in writing, after the Effective Date, that either party must obtain an additional license from an independent Third Party in order for Roche or PDL to manufacture, use, import, offer for sale or sell Daclizumab and if PDL and Roche agree on the terms of such license, then such license shall be deemed a Third Party License and the parties shall, subject to Sections 2.3, 7.4(c) and 7.4(d), share the cost of such Third Party License [CONFIDENTIAL TREATMENT REQUESTED].  Such cost includes license fees and any other fixed costs associated with such Third Party License as well as any royalties.  The parties shall, within [CONFIDENTIAL TREATMENT REQUESTED] of the end of each [CONFIDENTIAL TREATMENT REQUESTED], reimburse each other in accordance with this Section 7.4 to effect a [CONFIDENTIAL TREATMENT REQUESTED] of such license fees and other fixed costs.

(c)      Notwithstanding anything to the contrary herein, the following mechanism shall apply to the royalty portion of any Third Party Licenses to the extent such royalties arise due to sales of Daclizumab by Roche or its Affiliates or sublicensees during the time that Roche is obligated to pay royalties to PDL pursuant to Section 7.2(a):  (i) PDL’s share of such Third Party royalties shall be accrued against and deducted from any amounts due to PDL from Roche pursuant to Section 7.2(a) if Roche pays the royalties due under the Third Party License to such Third Party, and (ii) Roche’s share of the royalties portion of the cost of any Third Party License shall be accrued in favor of and added to any amounts due to PDL from Roche pursuant to Section 7.2(a) if PDL pays the royalties due under the Third Party License to such Third Party; provided, however, that the total amounts of all deductions made by Roche pursuant to clause (i) above (without taking into account any additions made pursuant to clause (ii)) shall not exceed [CONFIDENTIAL TREATMENT REQUESTED] of the amount that would otherwise be due to PDL, pursuant to Section 7.2(a), in any calendar quarter if no adjustments were permitted to account for payments made pursuant to Third Party Licenses;  provided further that the sum of Roche’s royalty obligations to PDL under Section 7.2(a) in any calendar quarter, plus Roche’s share of those royalties payable for such calendar quarter to Third Parties pursuant to Third Party Licenses shall not exceed [CONFIDENTIAL TREATMENT REQUESTED] of the amount that would otherwise be due to PDL, pursuant to Section 7.2(a), in such calendar quarter if no adjustments were permitted to account for payments made pursuant to Third Party Licenses.  Royalty payments made by Roche or PDL pursuant to Third Party Licenses that, due to the limitations set forth in the preceding sentence, cannot be deducted from, or added to, the amount to be paid to PDL by Roche under Section 7.2(a), may be carried forward to subsequent calendar quarters.  An example of the foregoing principles is set forth in Appendix D.

(d)      Notwithstanding anything to the contrary herein, the following mechanism shall apply to the royalty portion of any Third Party Licenses to the extent such royalties arise due to sales of Daclizumab by PDL or its Affiliates or sublicensees during the time that PDL is obligated to pay royalties to Roche, pursuant to Section 7.2(c):  (i) Roche’s share of such Third Party royalties shall be accrued against and deducted from any amounts due to Roche from PDL pursuant to Section 7.2(c) if PDL pays the royalties due under the Third Party License to such Third Party, and (ii) PDL’s share of such Third Party royalties shall be accrued in favor of and added to any amounts due to Roche from PDL pursuant to Section 7.2(c) if Roche pays the royalties due under the Third Party License to such Third Party; provided, however, that the royalty payments made by PDL to Roche pursuant to Section 7.2(c) shall not, as a result of the adjustments set forth in this Section 7.4(d), be reduced to less than [CONFIDENTIAL

31


TREATMENT REQUESTED] of PDL Net Sales.  Royalty payments made by Roche or PDL pursuant to Third Party Licenses that, due to the maximum royalty rate set forth in the preceding sentence, cannot be deducted from, or added to, the amount to be paid to PDL by Roche under Section 7.2(c), may be carried forward to subsequent calendar years.

(e)      If PDL exercises the Transplant Reversion or Roche exercises the Roche Put Right, then commencing on the Reversion Effective Date or the Put Right Effective Date (as applicable): (i) Roche shall not have any further obligation pursuant to this Section 7.4 to share the costs of, or pay directly, any royalties pursuant to any Third Party Licenses on account of sales of Daclizumab by PDL or its Affiliates or sublicensees, and (ii) PDL shall thereafter have sole responsibility for paying such royalties.

(f)      If the Exercise Period expires without PDL exercising the Transplant Reversion or Roche exercising the Roche Put Right, then:

(i)      commencing on [CONFIDENTIAL TREATMENT REQUESTED], with respect to sales of Daclizumab in the [CONFIDENTIAL TREATMENT REQUESTED] by Roche and its Affiliates and sublicensees, or [CONFIDENTIAL TREATMENT REQUESTED], with respect to sales of Daclizumab in the [CONFIDENTIAL TREATMENT REQUESTED] by Roche and its Affiliates and sublicensees, (A) PDL shall not have any further obligation pursuant to this Section 7.4 to share the costs of, or pay directly, any royalties pursuant to any Third Party Licenses on account of sales of Daclizumab by Roche or its Affiliates or sublicensees, and (B) Roche shall thereafter have sole responsibility for paying such royalties.

(ii)      commencing on, a country-by-country basis, with the expiration of PDL’s obligations to pay royalties to Roche, pursuant to Section 7.2(c), in such country with respect to the sale of Daclizumab by PDL and its Affiliates and sublicensees, (A) Roche shall not have any further obligation pursuant to this Section 7.4 to share the costs of, or pay directly, any royalties pursuant to any Third Party Licenses on account of sales of Daclizumab by PDL or its Affiliates or sublicensees, and (B) PDL shall thereafter have sole responsibility for paying such royalties.

7.5      Royalties on Termination.  If this Amended and Restated Worldwide Agreement is terminated pursuant to Sections 13.2, 13.3 or 13.4, then Roche shall continue to pay PDL, and PDL shall continue to pay Roche, as the case may be, any royalties earned pursuant to this Article VII prior to the date of termination.

7.6      Sublicenses.

(a)      Any Roche Net Sales or Roche Net Sales of Excluded Products by a Roche sublicensee shall be treated as Roche Net Sales or Roche Net Sales of Excluded Products of Roche, as the case may be, for the purposes of payments under Article VII.  If Roche, in accordance with Section 2.5(a) or (b), shall grant any sublicenses under this Amended and Restated Worldwide Agreement, then Roche shall obtain the written commitment of such sublicensees to abide by all applicable terms and conditions of this Amended and Restated

32


Worldwide Agreement and Roche shall remain responsible to PDL for the performance by such sublicensee of any and all terms.  All such sublicenses to any Excluded Products shall provide that such license terminates on any termination of the license granted pursuant to Section 2.5(b).  Any sublicense granted under the license in Section 2.5(a) shall expire as set forth in that Section 2.5(a).

(b)      Any PDL Net Sales by a PDL sublicensee shall be treated as PDL Net Sales of PDL for the purposes of payments under Article VII.  If PDL, in accordance with Section 2.1, shall grant any sublicenses under this Amended and Restated Worldwide Agreement, then PDL shall obtain the written commitment of such sublicensees to abide by all applicable terms and conditions of this Amended and Restated Worldwide Agreement and PDL shall remain responsible to Roche for the performance by such sublicensee of any and all terms.

(b)      Ownership of any cell lines developed under Article VI of the 1989 Agreements or delivered to Roche under Milestone #1 of Section 3.1 of the 1989 Agreements, together with their progeny and derivatives, shall remain vested at all times in PDL.

(c)      Roche may use the cell lines delivered to it under the 1989 Agreements, or their progeny or derivatives or the plasmids contained therein (the “Cell Line Derivatives”) solely to perform the Roche Commercialization Activities.  Furthermore, the Cell Line Derivatives may be used by Roche solely in connection with the genes encoding antibodies developed or provided by PDL.

(d)      On the earliest to occur of [CONFIDENTIAL TREATMENT REQUESTED] in the Roche Territory as permitted under this Amended and Restated Worldwide Agreement, Roche shall, on request by PDL, promptly return to PDL all cell lines provided by PDL under the 1989 Agreements and all Cell Line Derivatives.

(e)      PDL MAKES NO REPRESENTATIONS AND EXTENDS NO WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, WITH RESPECT TO ANY CELL LINES DELIVERED UNDER THE 1989 AGREEMENTS OR CELL LINE DERIVATIVES USED HEREUNDER, INCLUDING WITHOUT LIMITATION, ANY EXPRESS OR IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR NONINFRINGEMENT.  FOR CLARITY, PDL MAKES NO REPRESENTATIONS AND EXTENDS NO WARRANTIES OF ANY KIND THAT THE USE OF THE CELL LINES DELIVERED TO ROCHE OR THE CELL LINE DERIVATIVES WILL NOT INFRINGE ANY PATENT OR OTHER RIGHTS OF ANY THIRD PARTY.

X.  OWNERSHIP OF TECHNOLOGY AND INTELLECTUAL PROPERTY

10.1      PDL Technology.  Ownership of the PDL Know-How and PDL Patents shall remain vested at all times in PDL.  PDL expressly reserves under this Amended and Restated Worldwide Agreement (i) all rights to use the PDL Know-How, PDL’s rights under any Joint Roche-PDL Patents, and PDL Patents to make, have made, use, import, offer to sell and sell anywhere in the world all products within the Field that are other than Daclizumab for use in the Transplant Indications (unless and until the Roche Put Right or the Transplant Reversion is exercised) and other than any Excluded Product or any other product in the Excluded Field; and (ii) for all uses outside of the Field.  Following exercise of the Transplant Reversion or the Roche Put Right, PDL shall have the right to use such technology for any and all purposes other than products in the Excluded Field, which right shall be exclusive to Roche except as provided in Section 10.2.

36


10.2      Joint Inventions and Joint Roche-PDL Patents.  Subject to Article XI, ownership of Joint Inventions and Joint Roche-PDL Patents shall be vested jointly in PDL and Roche. Both parties shall at all times have the co-exclusive right within the Territory to practice, or to make, have made, use, import, offer for sale or sell any Joint Invention outside the Field under any Joint Roche-PDL Patent, and neither party shall be obligated to account to the other.  On the earlier of (i) the Reversion Effective Date, or (ii) the Put Right Effective Date, the following shall occur: (a) PDL shall have the exclusive right to practice, and to make, have made, use, import, offer for sale or sell any Joint Invention in the Field (but not in the Excluded Field) under any Joint Roche-PDL Patent, and (b) Roche shall have the exclusive right to practice, and to make, have made, use, import, offer for sale or sell any Joint Invention solely in the Excluded Field, in each case, without restriction and without any obligation to account to the other party.  As used herein, a right to practice any Joint Roche-PDL Patent for a particular purpose without any obligation to account shall include the right to grant licenses for such purpose without the consent of the other party.  To the extent either party needs the consent of the other party to exploit its co-exclusive or exclusive rights with respect to Joint Roche-PDL Patents, including the right to sublicense or enforce such Joint Roche-PDL Patents, the other party shall cooperate with the party making such a request and promptly supply all needed consents, signatures and the like.  In the event the Roche Put Right and the Transplant Reversion both expire unexercised, each party shall have the co-exclusive right to practice, and to make, have made, use, import, offer for sale or sell any Joint Invention in the Field under any Joint Roche-PDL Patent, subject to the license grants set forth in Article II.

10.3      Roche Technology.  PDL hereby acknowledges that, except as expressly provided herein, this Amended and Restated Worldwide Agreement does not grant PDL any ownership rights in the Roche Inventions, Roche Patents and Roche Know-How.  Roche hereby confirms the rights of PDL to certain license grants to Roche Patents and Roche Know-How as provided in Section 2.1 of this Amended and Restated Worldwide Agreement.

10.4      Trademarks.

(a)      Until the Reversion Effective Date or Put Right Effective Date, Roche shall exclusively own all Trademarks, and the exclusive right to use them in the Roche Territory in connection with the marketing and promotion of Daclizumab.  Roche shall have no right to use the Trademarks, or any other marks confusingly similar to the Trademarks, in connection with the promotion, sale or marketing of any other product, including any Excluded Product.

(b)      PDL shall have the right to select any and all AI Trademarks; provided such AI Trademarks are not confusingly similar to the Trademarks (unless otherwise agreed), and PDL shall retain ownership of the AI Trademarks and the exclusive right to use them in connection with the promotion, marketing and sale of Daclizumab for AI or any Other Indications.

(c)      Each party shall be responsible for selection, prosecution, maintenance and enforcement of its own trademarks, and shall indemnify and defend the other from any Third Party claims arising from the indemnifying party’s use of such marks.  At the request [CONFIDENTIAL TREATMENT REQUESTED] of PDL, Roche shall file trademark registration applications for, and procure and maintain registration of, the trademark “Zenapax®” in any

37


country in the Territory in which Roche, as of the Effective Date, has not made such application or procured such registration.  All such applications and registrations shall be deemed to be Trademarks.

(d)      Roche shall assign the Trademarks to PDL upon exercise of either the Transplant Reversion or the Roche Put Right, as provided for in Section 5.4(f).

XI.  PATENT PROSECUTION

11.1      Sole PDL Patents and Roche Owned Patents.

(a)      PDL agrees to prosecute and reasonably maintain all of the patents and applications included within the Sole PDL Patents, to the extent it has the rights to do so, and Roche agrees to prosecute and reasonably maintain the Roche Owned Patents, to the extent it has the rights to do so from any co-owner of such Roche Owned Patents.  The parties agree and acknowledge that the Roche Owned Patents listed on Schedule 2.8(a) are co-owned by Roche and a Third Party, and are governed by the [CONFIDENTIAL TREATMENT REQUESTED] (the “Joint Patent Agreement”) which provides, among other things, that Roche undertake certain obligations in order to continue to maintain its [CONFIDENTIAL TREATMENT REQUESTED] in the Roche Owned Patent.  Promptly after the Effective Date, to the extent that Roche is permitted to do so, Roche shall provide to PDL a copy of the Joint Patent Agreement, and the Roche Owned Patent for PDL’s review such that PDL may determine whether and to what extent, it intends that such Joint Patent Agreement and Roche Owned Patent be assigned to PDL in the event of the Transplant Reversion or the exercise of the Roche Put Right.

(b)      The party responsible for such patent (“Responsible Party”) shall bear all costs and expenses for such prosecution and maintenance. On the reasonable request of the Responsible Party, the other party shall cooperate, in all reasonable ways, in connection with the prosecution of all patent applications included within the Sole PDL Patents or Roche Owned Patents, as the case may be.  Should the Responsible Party decide that it is no longer interested in maintaining or prosecuting a Sole PDL Patent or Roche Owned Patent, as the case may be, it shall promptly advise the other party thereof and, at the request of such other party, PDL and Roche shall negotiate in good faith to determine an appropriate course of action in the interests of both parties.  If any Sole PDL Patents are assigned to Roche, Roche will thereafter prosecute and reasonably maintain such Sole PDL Patents at Roche’s own cost to the extent that Roche desires to do so, provided that to the extent such Sole PDL Patent contains claims outside the Field (or, following either the Reversion Effective Date or the Put Right Effective Date, outside the Excluded Field only), PDL and its Affiliates shall have a worldwide immunity from suit thereunder.  If Roche’s interest in any Roche Owned Patents is assigned to PDL, PDL will thereafter prosecute and reasonably maintain such Roche Owned Patent at PDL’s own cost to the extent that PDL desires to do so, provided that to the extent such Roche Owned Patent contains claims outside the Field (or following either the Reversion Effective Date or the Put Right Effective Date, outside the Excluded Field only), Roche and its Affiliates shall have a worldwide immunity from suit thereunder.   In the event Roche’s interest in the Roche Owned Patents is assigned to PDL pursuant to Section 5.4(e), Roche shall have no further rights with respect thereto under this Section 11.1 except those set forth in the penultimate sentence of this Section 11.1.

38


11.2      Joint Inventions.

(a)      PDL will have the first right of election to file priority patent applications for Joint Inventions in any country in the world.  If PDL declines to file such applications then Roche may do so.

(b)      The party not performing the priority patent filings for Joint Inventions pursuant to this Section 11.2 undertakes without cost to the filing party to obtain all necessary assignment documents for the filing party, to render all signatures that shall be necessary for such patent filings and to assist the filing party in all other reasonable ways that are necessary for the issuance of the patents involved as well as for the maintenance and prosecution of such patents.  The party not performing the patent filings shall on request be authorized by the other party to have access to the files concerning such patents in any patent offices in the world.

(c)      The party performing the priority patent filings for Joint Inventions pursuant to this Section 11.2 undertakes to perform, at its cost and expense, the corresponding convention filings from case to case, after having discussed the countries for foreign filings with the other party.

(d)      Should the Responsible Party decide that it is no longer interested in maintaining or prosecuting a Joint Roche-PDL Patent, it shall promptly advise the other party thereof.  On the written request of such other party, such Joint Roche-PDL Patent shall be assigned to the other party at no cost to the assignee.  If any such patents or patent applications are assigned to Roche, they shall then be deemed to be a Sole Roche Patent and, to the extent such Joint Roche-PDL Patent contains claims outside the Field (or, following the Reversion Effective Date or the Put Right Effective Date, outside the Excluded Field), PDL and its Affiliates shall have a worldwide immunity from suit thereunder.  If any such patents or patent applications are assigned to PDL, they shall then be deemed to be a Sole PDL Patent and, to the extent such Joint Roche-PDL Patents contain claims outside the Field, Roche and its Affiliates shall have a worldwide immunity from suit thereunder.

11.3      General Procedures.  Until the Reversion Effective Date, the Put Right Effective Date or the expiration of the Exercise Period without PDL exercising the Transplant Reversion, the parties shall observe the following procedures for patent applications for inventions arising from this Amended and Restated Worldwide Agreement:

(a)      As soon as one of the parties concludes that it wishes to file a patent application covering an invention in the Field, it shall immediately inform the other party thereof and consult about the filing procedures concerning such patent application.  For this purpose, such party will provide the other party with the determination of inventors and scope of claims as early as possible.  Should a party be faced with possible loss of rights, such communications may take place promptly after filing a convention application.

(b)      The party performing any priority patent filings as described above shall be obliged to prosecute and reasonably maintain such applications and any patents resulting therefrom and will have to bear the costs associated therewith.  On request of the party performing

39


the filing, the other party will cooperate, in all reasonable ways, in connection with the prosecution of all such patent applications relating to inventions.  The party performing the filing shall advise the other party of any substantial action or development in the prosecution of its patent applications and patents, in particular of the question of scope, the issuance of, or the rejection of, an interference involving or an opposition to any respective patent application or patent.

(c)      Inventions and other intellectual property made by either party outside the Field shall be excluded from the provisions of this Amended and Restated Worldwide Agreement and shall belong solely to the party having made the invention or other intellectual property.

11.4      Reimbursement for Costs of Patent Applications for Transplant Indications.

(a)      No Reimbursement.  As of the Effective Date, PDL shall be responsible for all ex parte out-of-pocket expenses incurred by PDL after the Effective Date in connection with the prosecution and maintenance in the Territory of patent applications and patents included within the PDL Patents or Joint Roche-PDL Patents for which PDL makes filings with respect to Transplant Indications pursuant to Article XI of this Amended and Restated Worldwide Agreement.

(b)      PDL Control.  After either the Reversion Effective Date or the Put Right Effective Date, PDL shall have full control over the strategy and decisions with respect to the filing of any patent applications and patents related to Transplant Indications in the Territory.  Roche agrees to cooperate with and reasonably assist PDL in the preparation of any patent applications and the maintenance of any patents.  Prior to the Reversion Effective Date or the Put Right Effective Date, PDL shall consult Roche with respect to its patent prosecution strategy and decisions, as follows:  Prior to the filing of a patent application in the Territory for Transplant Indications, PDL shall inform Roche concerning such proposed filing and shall consult with Roche concerning the proposed filing procedures, including specifically the determination of scope of any such patent and countries in which such application is to be filed.  PDL shall regularly advise Roche of any substantial action or development in the prosecution of its patent applications and patents in the Territory related to the Transplant Indications, in particular of the question of scope of, the issuance of, the rejection of, or an opposition to any respective patent application or patent.

(c)      Accrued Transplant Foreign Filing Expenses.  Transplant Foreign Filing Expenses accrued prior to [CONFIDENTIAL TREATMENT REQUESTED] shall remain creditable against royalties payable by Roche to PDL in the Territory (excluding the U.S., including its territories and possessions), as provided in Section 7.3 of this Amended and Restated Worldwide Agreement.

11.5      Reimbursement for Costs of Patent Applications for Autoimmune Indications.

(a)      No Reimbursement.  PDL shall be responsible for all ex parte out-of-pocket expenses incurred by PDL after the Effective Date in connection with the prosecution and maintenance in the Territory of patent applications and patents included within the PDL Patents or

40


Joint Roche-PDL Patents for which PDL makes filings with respect to Autoimmune Indications pursuant to Article XI of this Amended and Restated Worldwide Agreement.

(b)      PDL Control.  PDL shall have full control over the strategy and decisions with respect to the filing of any patent applications and patents related to Autoimmune Indications in the Territory.  Roche agrees to cooperate with and reasonably assist PDL in the preparation of any patent applications and the maintenance of any patents.

11.6      No Reimbursement for Roche’s Costs of Patent Applications.  Roche shall be responsible for all ex parte out-of-pocket expenses incurred by Roche after the Effective Date in connection with the prosecution and maintenance in the Territory of patent applications and patents included within the Roche Owned Patents or Joint Roche-PDL Patents for which Roche makes filings pursuant to this Article XI of this Amended and Restated Worldwide Agreement.

XII.   ENFORCEMENT AND DEFENSE OF PATENTS

12.1      Sole Patents.

(a)      Except for enforcement or revocation actions involving Sole PDL Patents or Roche Owned Patents outside the Field, in the event of any action against a Third Party for infringement of any claim in any issued patent within the Sole PDL Patents or Roche Owned Patents, as the case may be, or the institution by a Third Party of any proceedings for the revocation of any such claim, each party will notify the other promptly and, following such notification, the parties shall confer.  [CONFIDENTIAL TREATMENT REQUESTED] shall have the right, but not the obligation, to prosecute such actions or to defend such proceedings involving the Sole PDL Patents at its own expense, in its own name and entirely under its own direction and control.  [CONFIDENTIAL TREATMENT REQUESTED] shall have the right, but not the obligation, to prosecute such actions or to defend such proceedings involving the Roche Owned Patents at its own expense, in its own name and entirely under its own direction and control.

(b)      If a party with the first right hereunder elects not to prosecute any action for infringement or to defend any proceeding for revocation of any claims in any issued patent within the Sole PDL Patents (other than those Sole PDL Patents for which PDL [CONFIDENTIAL TREATMENT REQUESTED]) or Roche Owned Patents (other than those Roche Owned Patents [CONFIDENTIAL TREATMENT REQUESTED]), as the case may be, within [CONFIDENTIAL TREATMENT REQUESTED] of being requested by the other party to do so, the other party may prosecute such action or defend such proceeding at its own expense, in its own name and entirely under its own direction and control.  This Section 12.1(b) shall expire on the Reversion Effective Date or the Put Right Effective Date.

(c)      In any event, the party bringing an action (“Acting Party”) pursuant to this Section 12.1 shall solicit, and seriously consider in good faith the non-acting party’s input with respect to all material aspects of such action, including without limitation, the development of the litigation strategy and the execution thereof.  In furtherance and not in limitation of the foregoing, the Acting Party shall keep the other party promptly and fully informed of the status of any such

41


action, and the non-acting party shall have the right to review and comment on the Acting Party’s activities related thereto. The obligations of this Section 12.1(c) shall not apply to PDL as the Acting Party after either the Reversion Effective Date or the Put Right Effective Date.

(d)      Each party will reasonably assist the Acting Party in any such action or proceeding being prosecuted or defended by the Acting Party, if so requested by the Acting Party or required by law.  Without limiting the generality of the foregoing, the non-acting party agrees to join such action or proceeding if required by law to maintain such action or proceeding.  The Acting Party will pay or reimburse the assisting party for all costs, expenses and liabilities that the assisting party may incur or suffer in affording assistance to such actions or proceedings.  No settlement of any such action or defense that restricts the scope or affects the enforceability of PDL Know-How or Sole PDL Patents may be entered into by either PDL (if it would affect Roche’s rights under this Agreement) or Roche without the prior consent of the other party hereto, [CONFIDENTIAL TREATMENT REQUESTED].  No settlement of any such action or defense that restricts the scope or affects the enforceability of Roche Know-How or Roche Owned Patents may be entered into by either PDL or Roche without the prior consent of the other party hereto (if it would affect the other party’s rights under this Agreement, [CONFIDENTIAL TREATMENT REQUESTED].  The consent obligations of this Section 12.1(d) shall not apply to PDL as the Acting Party after either the Reversion Effective Date or the Put Right Effective Date.

(e)      If either party elects to prosecute an action for infringement or to defend any proceedings for revocation of any claims pursuant to this Section 12.1 and subsequently ceases to continue or withdraws from such action or defense, it shall forthwith so notify the other party in writing and the other party may substitute itself for the withdrawing party and the parties’ respective rights and obligations under this Section 12.1 shall be reversed. The obligations of this Section 12.1(e) shall not apply to PDL as the Acting Party after either the Reversion Effective Date or the Put Right Effective Date.

12.2      Joint Roche-PDL Patents.  In the event of any action against a Third Party for infringement of any claim in any issued patent within the Joint Roche-PDL Patents, or the institution by a Third Party of any proceedings for the revocation of any such claim, each party will notify the other promptly and, following such notification, the parties shall confer to determine whether either or both parties shall control the prosecution or defense of such action or proceeding and who shall bear the costs thereof.  If both parties wish to control the prosecution or defense of such action or proceeding and the parties are unable to reach agreement within [CONFIDENTIAL TREATMENT REQUESTED] of the notification referred to above, then (a) with respect to alleged infringement in the [CONFIDENTIAL TREATMENT REQUESTED], [CONFIDENTIAL TREATMENT REQUESTED] shall have the exclusive right to bring such action or defend such proceeding at its own expense, in its own name and entirely under its own direction, (b) with respect to alleged infringement in the [CONFIDENTIAL TREATMENT REQUESTED], [CONFIDENTIAL TREATMENT REQUESTED] shall have the exclusive right to bring such action or defend such proceeding at its own expense, in its own name and entirely under its own direction; and (c) with respect to alleged infringement [CONFIDENTIAL TREATMENT REQUESTED], [CONFIDENTIAL TREATMENT REQUESTED] shall have the right to bring such action or defend such proceeding at its own expense, in its own name and entirely under its own direction and control; provided, however, that if both parties elect to

42


prosecute or defend, each party shall bear its own expenses but both parties shall have equal control over such prosecution or defense.  No settlement of any action or defense that restricts the scope or affects the enforceability of Joint Roche-PDL Patents may be entered into by either PDL or Roche without the prior consent of the other party hereto, which consent shall not be unreasonably withheld.  In any event, the Acting Party pursuant to this Section 12.2 shall solicit, and seriously consider in good faith the other party’s input with respect to all material aspects of such action, including without limitation, the development of the litigation strategy and the execution thereof.  In furtherance and not in limitation of the foregoing, the Acting Party shall keep the other party promptly and fully informed of the status of any such action, and the other party shall have the right to review and comment on the Acting Party’s activities related thereto.

12.3      Distribution of Proceeds.  In the event either party exercises the rights conferred in Section 12.1 or 12.2 hereof, and recovers any damages or other sums in such action, suit or proceeding or in settlement thereof, such damages or other sums recovered shall first be applied to reimburse the parties for all costs and expenses incurred in connection therewith, including reasonable attorneys’ fees necessarily involved in the prosecution and/or defense of any suit or proceeding and, if after such reimbursement any funds shall remain from such damages or other sums recovered, said remaining recovery shall belong to [CONFIDENTIAL TREATMENT REQUESTED]; provided, however, that any remaining recovery by the party exercising its rights for a Joint Roche-PDL Patent with respect to alleged infringement outside the Field shall be shared, with [CONFIDENTIAL TREATMENT REQUESTED] of such remaining recovery to Roche and [CONFIDENTIAL TREATMENT REQUESTED] of such remaining recovery to PDL.

12.4      Defense of Infringement Actions.

(a)      Roche shall defend at its own cost any infringement suit that may be brought against PDL or Roche on account of the development, manufacture, production, use, importation, offer for sale, or sale of Daclizumab or Excluded Products by Roche, and shall indemnify and hold PDL harmless against any such patent or other infringement suits, and any claims, losses, damages, liabilities, expenses, including reasonable attorneys’ fees and cost, that may be incurred by PDL therein or in settlement thereof.  Any and all settlements that restrict the scope or enforceability of PDL Know-How or PDL Patents must be approved by PDL, in its sole and absolute discretion, before execution by Roche.  Any and all settlements that restrict the scope or enforceability of Joint Roche-PDL Patents or Sole Roche Patents (other than those Sole Roche Patents co-owned by a Third Party) must be approved by PDL before execution by Roche, such approval not to be unreasonably withheld.  PDL shall not be required to approve any settlement that does not include as a condition thereof the granting to PDL of a full and unconditional release of claims.

(b)      PDL shall defend at its own cost any infringement suit that may be brought against Roche or PDL on account of the development, manufacture, production, use, importation, offer for sale, or sale of Licensed Products  by PDL, and shall indemnify and hold Roche harmless against any such patent or other infringement suits, and any claims, losses, damages, liabilities, expenses, including reasonable attorneys’ fees and cost, that may be incurred by Roche therein or in settlement thereof.  Any and all settlements that restrict the scope or enforceability of Roche

43


Know-How or Roche Patents must be approved by Roche, in its sole and absolute discretion, before execution by PDL.  Any and all settlements that restrict the scope or enforceability of Joint Roche-PDL Patents must be approved by Roche before execution by PDL, such approval not to be unreasonably withheld.  Roche shall not be required to approve any settlement that does not include as a condition thereof the granting to Roche of a full and unconditional release of claims.  [CONFIDENTIAL TREATMENT REQUESTED]

12.5      Right to Counsel.  Each party to this Amended and Restated Worldwide Agreement shall always have the right to be represented by counsel of its own selection and its own expense in any suit or other action instituted by the other for infringement, under the terms of this Amended and Restated Worldwide Agreement.

XIII.  TERM AND TERMINATION

13.1      Term.  Unless earlier terminated pursuant to the terms of this Article XIII, this Amended and Restated Worldwide Agreement shall go into effect on the Effective Date and shall remain in effect until the latest of (i) expiration of the last to expire PDL Patents; (ii) expiration of the last to expire Roche Patents; (iii) expiration of PDL’s payment obligations hereunder; or (iv) expiration of Roche’s payment obligations hereunder.  On expiration of this Amended and Restated Worldwide Agreement, any exclusive licenses then in effect under any Roche Know-How or PDL Know-How will convert to fully paid, non-exclusive licenses.

13.2      Termination by Mutual Agreement.  This Amended and Restated Worldwide Agreement may be terminated by the written agreement of both parties.

13.3      Termination by PDL on Roche Default.  If, during the period commencing on the Effective Date and terminating on the earlier of Reversion Effective Date or the Put Right Effective Date, Roche defaults in the performance of, or fails to be in compliance with, any material agreement, condition or covenant of this Amended and Restated Worldwide Agreement with respect to either (a) the rights PDL grants to Roche under Article II of this Amended and Restated Worldwide Agreement, including royalties and consideration due from Roche to PDL under Article VII, or (b) the Transplant Reversion granted under Article V, then PDL may terminate any or all of the rights and licenses granted to Roche under Section 2.5 of this Amended and Restated Worldwide Agreement at its option, at which time Roche’s right to promote, distribute and sell Daclizumab in the Roche Territory shall terminate as though PDL had exercised its Transplant Reversion, with all the same effect as though that were the case, but without the need for any payment of the Reversion Exercise Fee.  PDL shall have such right to so terminate Roche’s rights under this Section 13.3 only if such default or noncompliance shall not have been remedied, or steps initiated to remedy the same to PDL’s reasonable satisfaction, within [CONFIDENTIAL TREATMENT REQUESTED] after receipt by Roche of a written notice thereof from PDL.  It is expressly understood that PDL’s rights to terminate under this Section 13.3 are in effect only until the earlier of the Reversion Effective Date or the Put Right Effective Date, and that such rights expire with the expiration, without exercise, of the Transplant Reversion and the Roche Put Right.

44


13.4      Voluntary Termination Of License by Roche.

(a)      Roche shall have the right, in the event the Transplant Reversion and the Roche Put Right expire unexercised, to voluntarily terminate its licenses under Section 2.5(a), on six (6) months written notice.  On notice of such voluntary termination, Roche shall notify PDL of the amount of Daclizumab that Roche, its Affiliates, sublicensees and distributors then have on hand (“Inventory”).  Roche and its Affiliates, sublicensees and distributors shall thereupon be permitted to sell the Inventory, provided that PDL shall have the first option for a period not to exceed [CONFIDENTIAL TREATMENT REQUESTED] to purchase all or part of the Inventory at [CONFIDENTIAL TREATMENT REQUESTED].  If PDL fails to exercise its option to purchase all of the Inventory or for that part of the Inventory with respect to which the option is not exercised, then Roche will be free to sell such Inventory to Third Parties for a period not to exceed [CONFIDENTIAL TREATMENT REQUESTED] from the termination of PDL’s option.  In any event, Roche shall pay the royalties or other consideration due, if any, on the sale of such Inventory in the amounts and manner provided for in Articles VII and VIII.

(b)      Roche shall have the right at any time during the term of this Amended and Restated Worldwide Agreement, to voluntarily terminate its license granted under Section 2.5(b), on [CONFIDENTIAL TREATMENT REQUESTED] written notice to PDL.  In the event of such unilateral termination, Roche agrees to negotiate with PDL, on PDL’s request, for the transfer and/or license of any Roche owned or licensed intellectual property or technology relevant to the development and/or commercialization of the Excluded Products, in return for [CONFIDENTIAL TREATMENT REQUESTED].

13.5      Return of Materials.  On termination of this Amended and Restated Worldwide Agreement in whole by both parties pursuant to Section 13.2, by PDL pursuant to Section 13.3, or by Roche pursuant to Section 13.4, Roche forthwith shall (a) return to PDL all cell lines and their progeny, antibodies and other biological materials provided by PDL under the 1989 Agreements; and (b) subject to Section 13.4, at PDL’s cost, shall deliver to PDL then available supplies of Daclizumab.

XIV.  CONFIDENTIALITY, DISCLOSURE AND PUBLICATIONS

14.1      Confidentiality.

(a)      Generally.  During the term of this Amended and Restated Worldwide Agreement and for a period of [CONFIDENTIAL TREATMENT REQUESTED] following expiration or termination of this Amended and Restated Worldwide Agreement, each party shall maintain in confidence all information and materials including, but not limited to, cell lines, their progeny, and antibodies, disclosed by the other party hereto that such party knows or has reason to know are or contain trade secrets or other proprietary information of the other, including, without

45


limitation, information relating to the PDL Know-How, PDL Patents, Roche Know-How, Roche Patents, Joint Roche-PDL Patents, Joint Inventions and inventions of the other party, and the business plans of the other party, including, without limitation, information provided by either party to the other party hereto prior to the Effective Date, and shall not use such trade secrets or proprietary information for any purpose, including, without limitation, for the purpose of developing products in the Field except as permitted by this Amended and Restated Worldwide Agreement or disclose the same to anyone other than those of its Affiliates, sublicensees, prospective sublicensees, employees, consultants, agents or subcontractors as are necessary in connection with such party’s activities as contemplated in this Amended and Restated Worldwide Agreement.  Each party shall be responsible for ensuring compliance with these obligations by such party’s Affiliates, sublicensees, prospective sublicensees, employees, consultants, agents and subcontractors.  Each party shall use a similar effort to that which it uses to protect its own [CONFIDENTIAL TREATMENT REQUESTED] trade secrets or proprietary information to ensure that its Affiliates, sublicensees, employees, consultants, agents and subcontractors do not disclose or make any unauthorized use of trade secrets or proprietary information of the other party hereto.  Each party shall notify the other promptly on discovery of any unauthorized use or disclosure of the other’s trade secrets or proprietary information.

(b)      Additional Roche Obligations.  During the period commencing on the Effective Date and terminating on the earlier of Reversion Effective Date or the Put Right Effective Date, Roche agrees to maintain in confidence the Roche Know-How related to Daclizumab in a manner consistent with Roche’s maintenance of confidentiality with respect to know-how and trade secrets related to its other products and technologies and consistent with Roche’s past practices with respect to such Roche Know-How.

14.2      Exceptions.  The obligation of confidentiality contained in this Amended and Restated Worldwide Agreement shall not apply to the extent that (a) either party (the “Recipient”) is required to disclose information by order or regulation of a governmental agency or a court of competent jurisdiction or (b) the Recipient can demonstrate that (i) the disclosed information was at the time of such disclosure by the Recipient already in the public domain other than as a result of actions of the Recipient, its Affiliates, employees, licensees, agents or subcontractors, in violation hereof; (ii) the disclosed information was rightfully known by the Recipient or its Affiliates (as shown by its written records) prior to the date of disclosure to the Recipient in connection with the negotiation, execution or performance of this Amended and Restated Worldwide Agreement; or (iii) the disclosed information was received by the Recipient or its Affiliates on an unrestricted basis from a source unrelated to any party to this Amended and Restated Worldwide Agreement and not under a duty of confidentiality to the other party, or (c) the Recipient can demonstrate that disclosure to a regulatory authority is required by its product license approval process.

14.3      Publications.

(a)      Scientific Publications.  Prior to public disclosure or submission for publication of a manuscript describing the results of any scientific activity or collaboration between PDL and Roche in the Field, the party disclosing or submitting such a manuscript (“Disclosing Party”) shall send the other party (“Responding Party”) by expedited delivery a

46


copy of the manuscript to be submitted and shall allow the Responding Party a reasonable time period (not to exceed forty-five (45) days from the date of confirmed receipt) in which to determine whether the manuscript contains subject matter of which patent protection should be sought (prior to publication of such manuscript) for the purpose of protecting an invention, or whether the manuscript contains confidential information belonging to the Responding Party.  After the expiration of forty-five (45) days from the date of confirmed receipt of such manuscript, the Disclosing Party shall be free to submit such manuscript for publication and publish or otherwise disclose to the public such research results.  Should the Responding Party believe the subject matter of the manuscript contains confidential information or a patentable invention of substantial commercial value to the Responding Party, then prior to the expiration of forty-five (45) days from the date of confirmed receipt of such manuscript by the Responding Party, the Responding Party shall notify the Disclosing Party in writing of its determination that such manuscript contains such information or subject matter for which patent protection should be sought.  On receipt of such written notice from the Responding Party, the Disclosing Party shall delay public disclosure of such information or submission of the manuscript for an additional period of sixty (60) days to permit preparation and filing of a patent application on the disclosed subject matter.  The Disclosing Party shall thereafter be free to publish or disclose such information, except that the Disclosing Party may not disclose any confidential information of the Responding Party in violation of Sections 14.1 and 14.2 hereof.  Determination of authorship for any paper or patent shall be in accordance with accepted scientific practice.  Should any questions on authorship arise, this will be determined by good faith consultation between the respective heads of research for each of the parties.

(b)      Clinical Studies.  At any time prior to PDL’s exercise of the Transplant Reversion or Roche’s exercise of the Roche Put Right, if a party intends to publicly disclose or submit for publication a manuscript describing the results of any permitted scientific, preclinical or clinical study involving Daclizumab conducted by or on behalf of such party (the “Publishing Party”) or its Affiliates, the Publishing Party shall send the other party by expedited delivery a copy of the manuscript to be submitted and shall allow the other party a reasonable time period (such period to be stated in the transmittal and not to exceed forty-five (45) days from the date of confirmed receipt by the other party) to review the manuscript, including for the purpose of determining whether the manuscript contains information which is reasonably likely to have a material adverse impact on Daclizumab for either Transplant Indications or Autoimmune Indications, as the case may be, in the Territory or confidential information belonging to the other party.  After the expiration of such stated reasonable period from the date of confirmed receipt by the other party of such manuscript, the Publishing Party shall be free to submit such manuscript for publication and publish or otherwise disclose to the public such research results.  During such stated reasonable period, if the other party believes the manuscript contains information that is reasonably likely to have a material adverse impact on Daclizumab for Transplant Indications or Autoimmune Indications, as the case may be, in the Territory, then prior to the expiration of the stated period above, the other party shall notify the Publishing Party in writing of its determination and the reasons therefor.  On receipt of such written notice from the other party, the Publishing Party shall confer with the other party and shall attempt in good faith to resolve such concerns before the Publishing Party makes any public disclosure of such information or submission of the manuscript.   After the Reversion Effective Date or the Put Right Effective Date, PDL shall have

47


the sole right to publish or otherwise publicly disclose, without the consent of Roche, the results of any scientific, preclinical and clinical data involving Daclizumab conducted by or on behalf of PDL or Roche or their Affiliates.

XV.  DISPUTE RESOLUTION

15.1      Arbitration.  Except as expressly provided herein, any claim, dispute or controversy arising out of or in connection with or relating to this Amended and Restated Worldwide Agreement or the breach or alleged breach thereof shall be submitted by the parties to arbitration by the American Arbitration Association (“AAA”) in Santa Clara County, California, under the commercial rules then in effect for that AAA except as provided herein.  All proceedings shall be held in English and a transcribed record prepared in English.  The parties shall choose, by mutual agreement, one arbitrator within thirty (30) days of receipt of notice of the intent to arbitrate.  If no arbitrator is appointed within the times herein provided or any extension of time that is mutually agreed on, the AAA shall make such appointment within thirty (30) days of such failure.  The award rendered by the arbitrator shall include costs of arbitration, reasonable attorneys’ fees and reasonable costs for expert and other witnesses, and judgment on such award may be entered in any court having jurisdiction thereof.  The parties shall be entitled to discovery as provided in Sections 1283.05 and 1283.1 of the Code of Civil Procedure of the State of California, whether or not the California Arbitration Act is deemed to apply to said arbitration.  Nothing in this Amended and Restated Worldwide Agreement shall be deemed as preventing either party from seeking injunctive relief (or any other provisional remedy) from any court having jurisdiction over the parties and the subject matter of the dispute as necessary to protect either party’s name, proprietary information, trade secrets, know-how or any other proprietary right.  If the issues in dispute involve scientific or technical matters, any arbitrator chosen hereunder shall have educational training and/or experience sufficient to demonstrate a reasonable level of knowledge in the field of biotechnology.  Judgment on the award rendered by the arbitrator may be entered in any court having jurisdiction thereof.

XVI.  FORCE MAJEURE

16.1      No Control.  If either party shall be delayed, interrupted in or prevented from the performance of any obligation hereunder by reason of force majeure including an act of God, fire, flood, earthquake, war (declared or undeclared), public disaster, act of terrorism, strike or labor differences, governmental enactment, rule or regulation, or any other cause beyond such party’s control, such party shall not be liable to the other therefor; and the time for performance of such obligation shall be extended for a period equal to the duration of the force majeure which occasioned the delay, interruption or prevention.  The party invoking such force majeure rights of this Section 16.1 must notify the other party by courier or overnight dispatch (e.g., Federal Express) within a period of fifteen (15) days of both the first and last day of the force majeure unless the force majeure renders such notification impossible in which case notification will be made as soon as possible.  If the delay resulting from the force majeure exceeds six (6) months, both parties shall consult together to find an appropriate solution.

48


XVII.  MISCELLANEOUS

17.1      Representations.  Each party represents and warrants to the other party hereto that, except as may otherwise be disclosed in writing to such party:

(a)      each party has the full right and authority to enter into this Amended and Restated Worldwide Agreement; and

(b)      to the best knowledge of the party after reasonable investigation, no Third Party has any right, title or interest in the PDL Patents or PDL Know-How, Roche Know-How or Roche Patents, as the case may be, or in the Joint PDL-Roche Patents, as the result of such Third Party’s former employment of any employee of that party.

17.2      Assignment.  Either party may assign this Amended and Restated Worldwide Agreement and the licenses herein granted (a) to any Affiliate of such party without the consent of the other party, provided that such party remains fully liable for the performance of such party’s obligations hereunder by such Affiliate, or (b) to any Third Party, on the prior written consent of the other party, not to be unreasonably withheld; and (c) without the consent of the other party, to any Third Party purchaser of all or substantially all of the business unit to which this Amended and Restated Worldwide Agreement relates, which in the case of PDL, shall mean the Daclizumab business, and in the case of Roche, shall mean Roche’s therapeutic antibody business or transplant therapeutic business.  The parties agree that it would be reasonable for a party to withhold consent to the other party’s proposed assignment of this Amended and Restated Worldwide Agreement to an entity, that is, as of the time of such proposed assignment, [CONFIDENTIAL TREATMENT REQUESTED] (in at least one [CONFIDENTIAL TREATMENT REQUESTED] with [CONFIDENTIAL TREATMENT REQUESTED]), or [CONFIDENTIAL TREATMENT REQUESTED] in any [CONFIDENTIAL TREATMENT REQUESTED] any [CONFIDENTIAL TREATMENT REQUESTED] for the [CONFIDENTIAL TREATMENT REQUESTED] of [CONFIDENTIAL TREATMENT REQUESTED] in any [CONFIDENTIAL TREATMENT REQUESTED].  This Amended and Restated Worldwide Agreement shall be binding on and shall inure to the benefit of the permitted successors and assigns of the parties hereto.

17.3      Entire Agreement.  This Amended and Restated Worldwide Agreement, the Reversion Agreement between F. Roche and PDL dated March 4, 2002 (“Japan Reversion Agreement”), the Pharmacovigilance Agreement, and the Joint Defense Agreement dated June 20, 2000, constitute the entire agreement between the parties hereto with respect to the subject matter herein and, effective on the Effective Date, supersede all previous agreements (including the 1999 Agreements), whether written or oral, such superseding resulting in, among other things, the licenses granted thereunder having no further force or effect and being replaced by the licenses set forth in Article II of this Amended and Restated Worldwide Agreement.  Notwithstanding the foregoing, (a) certain provisions of the 1999 Agreements shall remain in force and effect, to the extent this Amended and Restated Worldwide Agreement so indicates by specific reference, and (b) any royalties or other payments accruing under the 1999 Agreements prior to the Effective Date shall remain due and payable.  This Amended and Restated Worldwide Agreement shall not be changed or modified orally, but only by an instrument in writing signed by both parties.

49


17.4      Releases.  The parties hereby confirm the releases contained in Section 15.4 of the 1999 PDL/Roche Agreement and in Section 11.4 of the F. Roche Agreement.

17.5      Severability.  If any provision of this Amended and Restated Worldwide Agreement is declared invalid by an arbitrator pursuant to Section 15.1 or by a court of last resort or by any court or other governmental body from the decision of which an appeal is not taken within the time provided by law, then and in such event, this Amended and Restated Worldwide Agreement will be deemed to have been terminated only as to the portion thereof that relates to the provision invalidated by that decision and only in the relevant jurisdiction, but this Amended and Restated Worldwide Agreement, in all other respects and all other jurisdictions, will remain in force; provided, however, that if the provision so invalidated is essential to the Amended and Restated Worldwide Agreement as a whole, then the parties shall negotiate in good faith to amend the terms hereof as nearly as practical to carry out the original intent of the parties, and, failing such amendment, either party may submit the matter to arbitration for resolution pursuant to Section 15.1.

17.6      Indemnification.

(a)      Roche agrees to defend, indemnify and hold harmless PDL, its trustees, officers, agents and employees from and against any and all Third Party suits, claims, acts, liabilities, demands, damages, expenses, and losses of any kind, including those resulting from death, personal injury, illness or property damage arising (i) out of the manufacture, distribution, use, testing, promotion, marketing or sale or other disposition, by Roche, an Affiliate of Roche, or any distributor, customer, sublicensee or representative of Roche or anyone in privity therewith (other than PDL), of (A) any Licensed Product, as defined in the 1999 Agreements, prior to the Effective Date, (B) Daclizumab or any Excluded Product on or after the Effective Date, or (C) any cell lines, their progeny, or other biological materials, method, process, device or apparatus licensed or provided by PDL pursuant to the 1989 Agreements, the 1999 Agreements or this Amended and Restated Worldwide Agreement; (ii) as a result of practicing a Joint Invention, or using PDL Know-How or PDL Patents licensed to Roche under this Amended and Restated Worldwide Agreement, except where such claim is based on the negligent acts of commission or omission of PDL; (iii) out of any breach by Roche of any representation, warranty or covenant of this Amended and Restated Worldwide Agreement; (iv) out of any violation of applicable law by an action, policy or procedure of Roche or its Affiliates; or (v) out of any negligence or willful misconduct of Roche or its Affiliates.

(b)      PDL agrees to defend, indemnify and hold harmless Roche, its trustees, officers, agents and employees harmless from and against any and all Third Party suits, claims, actions, liabilities, demands, damages, expenses, and losses of any kind, including those resulting from death, personal injury, illness or property damage arising (i) out of the manufacture, distribution, use, testing, promotion, marketing or sale or other disposition, by PDL, an Affiliate of PDL, or any distributor, customer, sublicensee or representative of PDL or anyone in privity therewith (other than Roche), of (A) Daclizumab prior to the Effective Date, or (B) Daclizumab or any Other Licensed Product on or after the Effective Date, or (C) any biological materials, method, process, device or apparatus licensed or provided by Roche pursuant to this Amended and Restated Worldwide Agreement; (ii) as a result of practicing a Joint Invention, or using Roche

50


Know-How or Roche Patents licensed to PDL under this Amended and Restated Worldwide Agreement, except where such claim is based on the negligent acts of commission or omission of Roche; (iii) out of any breach by PDL of any representation, warranty or covenant of this Amended and Restated Worldwide Agreement; (iv) out of any violation of applicable law by an action, policy or procedure of PDL or its Affiliates; (v) out of any negligence or willful misconduct of PDL or its Affiliates; or (vi) from any claim for failure to pay any license fee, royalty or other payment due on sales of Daclizumab or any Other Licensed Product by PDL or its Affiliates or sublicensees under any license agreement for any Roche Controlled Patents between Roche and any Third Party licensor that PDL elected not to take a sublicense under as provided in Section 2.8(b).

(c)      Procedure.  In the event of a claim by a Third Party against a party entitled to indemnification under this Amended and Restated Worldwide Agreement (“Indemnified Party”), the Indemnified Party shall promptly notify the other party (“Indemnifying Party”) in writing of the claim and the Indemnifying Party shall undertake and solely manage and control, at its sole expense, the defense of the claim and its settlement.  The Indemnified Party shall cooperate with the Indemnifying Party, including, as requested by the Indemnifying Party and at the Indemnifying Party’s cost, entering into a joint defense agreement.   The Indemnified Party may, at its option and expense, be represented in any such action or proceeding by counsel of its choice.  The Indemnifying Party shall not be liable for any litigation costs or expenses incurred by the Indemnified Party without the Indemnifying Party’s written consent.  The Indemnifying Party shall not settle any such claim unless such settlement fully and unconditionally releases the Indemnified Party from all liability relating thereto, unless the Indemnified Party otherwise agrees in writing.

17.7      Notices.  Any notice or report required or permitted to be given under this Amended and Restated Worldwide Agreement shall be in writing and shall be mailed by certified or registered mail, or telexed or telecopied and confirmed by mailing, as follows and shall be effective five (5) days after such mailing:
