 AGREEMENT 
 NOW THEREFORE, in
consideration of the mutual covenants herein contained and intending to be legally bound, the parties agree as follows: 
 1. DEFINITIONS 

All references to Exhibits, Articles and Sections shall be references to Exhibits, Articles and Sections of this Agreement. In addition, except as
otherwise expressly provided herein, the following terms in this Agreement shall have the following meanings: 
 1.01
“Affiliate” shall mean, with respect to a party hereto, any corporate or other entity which, directly or indirectly, controls, is controlled by, or is under common control with such party where “control” means the ownership
of not less than 50% of the voting shares of a 

  

 1 








 
corporation, or decision-making authority as to an unincorporated entity; provided that such entity shall be an Affiliate only so long as such control
exists. 
 1.02 “Combination Product(s)” shall mean any product containing both a pharmaceutically active agent or
ingredient which constitutes a Licensed Product and one or more other pharmaceutically active agents or ingredients which do not constitute Licensed Products. 
 1.03 “Licensed Product(s)” shall mean human therapeutic products of ELAN or
ELAN’s sublicensees that include an Antibody developed by ELAN binding to the alpha subunit of the VLA-4 integrin whose development, manufacture, import, use or sale would, but for a license under this Agreement, infringe a Valid Claim.
“Antibody” as used herein shall include, without limitation, monospecific and bispecific antibodies; less than full-length antibody forms such as Fv, Fab, and F(ab’)2; single-chain antibodies; and antibody conjugates bound to a toxin, label or other moiety. 
 1.04
“Net Sales” shall mean the aggregate gross revenues, whether in cash or in kind, derived by or payable from or on account of the sale of Licensed Products by ELAN, its Affiliates and its sublicensees to an independent third party not
an Affiliate or sublicensee of either ELAN or ELAN’s sublicensee, less amounts actually incurred or provided for (a) credits, allowances, discounts or rebates, if any, granted on account of price adjustments, recalls, rejection or return
of items previously sold, (b) excise and sales taxes, duties or other taxes imposed on and paid with respect to such sales (excluding income or franchise taxes of any kind) and (c) outer packing, freight and freight insurance costs. If
ELAN or any of its Affiliates or sublicensees receive any consideration (whether in cash or otherwise) in lieu of all or part of any royalties otherwise payable for any Licensed Product sold or otherwise transferred to an independent third party not
an Affiliate of the seller or transferor, the fair market value of such consideration on the date of such transfer as known to ELAN, or as reasonably estimated by ELAN if unknown, shall be included in the definition of Net Sales. For purposes of the
foregoing sentence, consideration paid to Elan from its Affiliates or sublicensees in the form of fees, milestones, collaboration payments or supply payments shall not be deemed consideration in lieu of royalties (i.e., not part of Net Sales)
hereunder if such consideration is not intended to and does not result in a reduction, credit, allowance, rebate or other offset against payment of any royalties otherwise payable for any Licensed Product sold or otherwise transferred to an
independent third party. 
 1.05 “PDL Patent Rights” means the patent applications or patents (as well as any foreign
counterparts thereto filed by PDL before or during the term of this Agreement) identified on Exhibit A, including any additions, continuations, continuations-in-part or divisions thereof or any substitute applications therefor;
any patents issued with respect to such patent applications, any reissues, extensions or patent term extensions of any such patents, and any confirmation patents or registration patents or patents of addition based on any such patents. 

1.06 “Valid Claim” means (a) any claim in any issued patent included in the PDL Patent Rights which would be infringed but for
the license granted under Section 2.01, and which claim has not been disclaimed or held unenforceable or invalid by a governmental agency or court of competent jurisdiction by a decision beyond right of review; and (b) any pending claim
under 

  

 2 








 
PDL Patent Rights which, if granted, would be infringed but for the license granted under Section 2.01, and which pending claim would be a Valid Claim
if the pending claim were treated as granted. 
 2. LICENSE 
 2.01 License Grant. Subject to the terms and conditions of this Agreement, PDL hereby grants and ELAN hereby accepts a worldwide nonexclusive license under the PDL Patent Rights, including the right to grant
sublicenses in accordance with Section 2.02, to make, have made, use and sell Licensed Products. 
 2.02 Limitation on Sublicenses;
Notification. ELAN shall have the right to grant sublicenses of its rights with respect to the Licensed Product under Section 2.01 to its Affiliates, including for purposes of this Agreement, Axogen Limited (“Axogen”), and such
Affiliates shall have the right to grant further sublicenses with respect to Licensed Products in accordance with the terms of this Agreement. ELAN and its Affiliates shall only grant sublicenses hereunder in connection with the assignment or
license by ELAN and its Affiliates of the Licensed Product to that sublicensee. ELAN shall provide a written summary to PDL within forty-five (45) days following the end of each calendar quarter during the term of this Agreement specifying the
name of each sublicensee, territory and scope of the rights sublicensed hereunder during that quarter. Notwithstanding the assignment or grant of a sublicense by ELAN or its Affiliates hereunder, ELAN shall remain obligated to pay all royalties due
to PDL with respect to the sale of Licensed Products by its assignee or sublicensee. In addition, the grant or any sublicenses under Section 2.01 shall be on terms and conditions which are subject to and subordinate to the terms of this
Agreement and ELAN shall remain fully responsible to PDL for the performance of any and all such terms by its sublicensees. 
 2.03 No
Other License Rights. ELAN expressly acknowledges and agrees that, except for the license expressly granted under Section 2.01, no rights to any other PDL patents, patent applications, know-how or licenses are included in this Agreement and
that any royalties or payments that may be due to third parties in order for ELAN to make, have made, use or sell Licensed Products shall be the sole responsibility of ELAN. 
 2.04 Certain Understandings. 
 (a)
[    ] 
 (b) Fee Payment. ELAN acknowledges that the payments under Section 3.01 are based on good faith
market projections provided by ELAN to PDL and ELAN represents that the projections as provided to PDL are the same as those used by ELAN internally at this time for initial marketing and development decisions of the Licensed Product. 
 3. PAYMENTS, ROYALTIES, REPORTS 
 3.01
Payments. In consideration for the license granted by PDL under Article 2 of this Agreement, ELAN shall pay to PDL the following amounts: 
 (a) Signing and Licensing Fee. ELAN shall pay to PDL a nonrefundable signing and licensing fee within ten (10) days of the Effective Date in the sum of [    ]. 
  

 3 








 (b) Development Milestone. Within ten (10) days of its determination to proceed with further
development of the Licensed Product following completion of the U.S. Phase II clinical study in multiple sclerosis designated as “AN100226-202” (the “Milestone Trial”), ELAN shall pay to PDL a nonrefundable milestone payment in
the sum of either (a) [            ] if paid on or prior to December 31, 1998, or (b) [            ] if paid after
December 31, 1998. In any event, ELAN shall notify PDL in writing of its determination to proceed with or to terminate further development of the Licensed Product not later than thirty (30) days following the earlier of (a) its review
of the preliminary results from the Milestone Trial, or (b) its public announcement or presentation of the results from the Milestone Trial. 
 3.02 Royalties to PDL. Subject to reduction for any offset as provided in Section 3.05, in further consideration of the rights and licenses granted under Article 2, ELAN shall pay to PDL a royalty of
[            ] of the Net Sales of all Licensed Products sold by ELAN or its Affiliates or sublicensees in each country until the last date on which there is a Valid Claim that, but for the
licenses granted to ELAN under this Agreement, would be infringed by the making, using, having made or sale of that Licensed Product in such country or by the manufacture of Licensed Product in the country of manufacture. 
 3.03 Sales Among Affiliates. Sales between and among ELAN and its Affiliates of Licensed Products which are subsequently resold or to be resold by
such Affiliates shall not be subject to royalty, but in such cases royalties shall accrue and be calculated on any subsequent sale of such Licensed Products to a non-Affiliate. 
 3.04 Combination Products. Net Sales in a particular country, in the case of Combination Products for which the pharmaceutically active agent or
ingredient constituting a Licensed Product and each of the other pharmaceutically active agents or ingredients not constituting Licensed Products have established market prices in that country when sold separately, shall be determined by multiplying
the Net Sales for each such Combination Product by a fraction, the numerator of which shall be the established market price for the Licensed Product(s) contained in the Combination Product and the denominator of which shall be the sum of the
established market prices for the Licensed Product(s) plus the established market prices for the other pharmaceutically active agents or ingredients contained in the Combination Product. When such separate market prices are not established in that
country, then the parties shall negotiate in good faith to determine a fair and equitable method of calculating Net Sales in that country for the Combination Product in question. 
 3.05 Annual Maintenance Fee. In further consideration of the licenses granted under
Article 2, not later than thirty (30) days following the third (3rd) anniversary of the Effective Date and not later than each
anniversary thereafter, ELAN shall pay PDL a nonrefundable annual maintenance fee in the amount of [            ]. An amount up to fifty percent (50%) of the annual maintenance fee
paid by ELAN hereunder beginning in the year in which a Biologics License Application (“BLA”) is filed with the U.S. Food and Drug Administration (or any successor thereto) with respect to a Licensed Product shall be creditable against
royalties payable to PDL pursuant to Section 3.02; provided that in no event shall any portion of the annual maintenance fees paid prior to the year in which a BLA is filed with respect to the Licensed Product be creditable against royalties
hereunder. 
  

 4 








 3.06 Currency Conversion. All amounts payable to PDL under this Agreement shall be payable in U.S.
Dollars by wire transfer to a bank account designated by PDL. In the case of royalties on Net Sales, all amounts payable shall first be calculated in the currency of sale and then converted into U.S. Dollars using the average of the daily exchange
rates for such currency quoted by Citibank, N.A. for each of the last five (5) banking days of each calendar quarter. 
 3.07 Royalty
Reports. 
 (a) Current Reports. ELAN agrees to make written reports and royalty payments to PDL within forty-five (45) days
after the close of each calendar quarter during the term of this Agreement, beginning with the calendar quarter in which the date of first sale following regulatory approval occurs. These reports shall show for the calendar quarter in question Net
Sales by ELAN, its Affiliates and sublicensees of the Licensed Products on a country-by-country basis, details of the quantities of Licensed Products sold in each country and the country of manufacture if different, applicable offsets and the net
royalty due to PDL thereon pursuant to Article 3. No later than at the time of the making of each such report, ELAN shall make any payment due to PDL of royalties for the period covered by such report. 
 (b) Termination Report. For each Licensed Product, ELAN also agrees to make a written report to PDL within ninety (90) days after the date on
which ELAN, its Affiliates or sublicensees last sell that Licensed Product stating in such report the same information required by quarterly reports for all such Licensed Products made, sold or otherwise disposed of which were not previously
reported to PDL. 
 3.08 Inspection. ELAN agrees to keep clear, accurate and complete records for a period of at least three (3)
years for each reporting period in which Net Sales occur showing the manufacturing, sales, use and other disposition of Licensed Products in sufficient detail to enable the royalties payable hereunder to be determined, and further agrees to permit
its books and records to be examined by an independent accounting firm selected by PDL and reasonably satisfactory to ELAN, from time-to-time to the extent necessary, but not more than once a year. Said independent accounting firm shall not be
required to disclose to PDL any information other than that relating to the accuracy of the reports and payments thereunder. Such examination is to be made at the expense of PDL, except in the event that the results of the audit reveal that ELAN
underpaid PDL by five percent (5%) or more, then the audit fees shall be paid by ELAN. Any such discrepancies will be promptly corrected by a payment or refund, as appropriate. 
 3.09 Withholding. 
 (a)
Payments. The amounts payable under Sections 3.01 and 3.05 shall represent the actual proceeds to be received by PDL, net of any withholding or other taxes or levies that may be applicable to such payments. PDL agrees to reasonably
cooperate with ELAN in obtaining a refund of any withholding taxes or levies paid by ELAN, if any, with respect to any payments to PDL hereunder. In the event that PDL is successful in obtaining any refund of tax withholding amounts paid by ELAN
under this Agreement, PDL agrees to promptly remit such refund amount to ELAN. 
  

 5 








 (b) Royalty Payments. ELAN may withhold from royalties due to PDL amounts for payment of any
withholding tax that ELAN, its Affiliates and sublicensees have paid to any taxing authority with respect to the royalty amounts due to PDL hereunder; provided, however, that the net amount payable to PDL shall in no event be reduced, on account of
non-U.S. withholding or other taxes, by more than ten (10) percent. ELAN agrees to reasonably cooperate with PDL in obtaining a foreign tax credit in the U.S. with respect to royalties due to PDL on the sale or manufacture of Licensed Products.

 4. PATENT PROSECUTION AND MAINTENANCE 
 4.01 Prosecution. PDL hereby agrees that, at its own expense it will use commercially reasonable efforts to: 
 (a)
prosecute any patent applications comprising the PDL Patent Rights and to secure the most extensive protection reasonably obtainable under the PDL Patent Rights; and 
 (b) maintain the claims under the PDL Patent Rights as valid and enforceable claims for the full term thereof. 
 4.02 Updates. Upon the written request of ELAN (which request shall not be made more than once per calendar year), PDL agrees to provide a written update of the information relating to the PDL Patent Rights as
set forth on Exhibit A. 
 4.03 Defense of PDL Patent Rights. With respect to the PDL Patent Rights licensed under
this Agreement, PDL at its sole cost and expense agrees to take all steps and proceedings and to undertake such other acts as PDL may, in its sole discretion, deem necessary or advisable to restrain any infringement or improper or unlawful use of
the PDL Patent Rights and to recover any actual or punitive compensation therefor. ELAN shall provide reasonable assistance to PDL and permit PDL to have the sole right to take such steps, conduct any such proceedings or undertake any such actions
to restrain any infringement or improper or unlawful use of the PDL Patent Rights, whether or not ELAN is a party to such steps, proceedings or actions. Any monies recovered from alleged infringers shall be retained by PDL. 
 4.04 Notification. ELAN shall promptly notify PDL in writing of any actual or suspected infringement of any PDL Patent Right, which notification
shall specify in reasonable detail the nature of such actual or suspected infringement. 
 5. REPRESENTATIONS AND WARRANTIES; INDEMNIFICATION
