 SECTION 2: DEVELOPMENT PHASE AND REGULATORY FILINGS 
  
 2.1    During the Development Phase, Dynal shall
use its good faith and commercially reasonable efforts to complete its responsibilities under the Work Plans in accordance with the standards and time frames stated therein and the terms and conditions of this Agreement. If Xcyte does not complete
its responsibilities under the Work Plans in accordance with the standards and time frames stated therein and/or the terms and conditions of this Agreement, Dynal shall not be entitled to terminate this Agreement therefor, but Dynal shall be

the development activities to be conducted through Phase I of the Development Phase, but only provide a general outline of the development activities to be conducted during Phase III of the Development Phase, and therefore, the parties shall after
the Signing Date, amend the Work Plans to detail the Phase III activities during the Development Phase, as mutually agreed by the parties. The parties shall use commercially reasonable efforts to so amend the Work Plans to detail the Phase III
activities by April 1, 2000. 
  
 2.2    The parties shall, promptly after the Signing Date, each designate a representative to act as a contact person for the other party and to coordinate and communicate between the parties with respect to each
party’s respective development activities under this Agreement during the Development Phase. A party may change its designee at any time by written notice to the other party. During the Development Phase, each party shall prepare and provide to
the other party written reports on a quarterly basis detailing its development activities and progress under the Work Plans under this Agreement, and each party shall also keep the other party generally updated on a monthly basis of its development
activities and progress under this Agreement. 
  
 2.3    As part of Dynal’s activities under the Work Plans, Dynal, at its cost, shall duly file with the FDA and the regulatory agencies in the countries included in the European Union (the
“EU”), and shall own, all DMFs that are to be filed in connection with the Products. With respect to countries in the Territory outside of the United States and the EU, Dynal shall, at Xcyte’s cost, if and as requested by
Xcyte, duly file with the regulatory agencies in such countries, and shall own, all DMFs for the Products. During the term of this Agreement and after the term of this Agreement upon non-renewal of this Agreement or termination of this Agreement
pursuant to Section 8.3 by Xcyte, Xcyte shall have the right to cross-reference all DMFs filed during the term of this Agreement by Dynal in the Territory as necessary to enable Xcyte to obtain or maintain marketing approval for use of the
Products in the Field. Xcyte or its Antibody suppliers shall duly file with the FDA and the applicable regulatory agencies in the Territory outside the United States and shall own all regulatory filings for the Antibodies. If Xcyte makes any
regulatory filings in the Territory relating to the Products and/or their use in the Field, Dynal shall have the right to cross-reference such regulatory filings in the Territory as necessary in connection with Dynal’s obligations under this
Agreement, including with respect to accomplishing activities under the Work Plans, making DMF filings for the Products and manufacturing and supplying the Products to Xcyte under this Agreement. If a regulatory agency in the Territory will not
grant marketing approval to Xcyte for use of the Products in the Field based upon a cross-reference to a DMF for the Products made by Dynal or its agent for the Field, and requires that Xcyte submit the information that is (or if not yet filed in
such country, would be) included in Dynal’s DMF for the Products in such country for the Field, Dynal shall provide the information that is (or if not yet filed in such country, would be) included in Dynal’s DMF for the Products for the
Field solely for Xcyte to include such information in its filing to the regulatory agency to obtain marketing approval for use of the Products in the Field in such country and for no other use or purpose; provided that Xcyte provides Dynal
with written confirmation from the regulatory agency in such country that the regulatory agency will not allow a cross-reference to Dynal’s DMF for the Product, and requires the information that is (or if not yet filed in such country, would
be) included in Dynal’s DMF for the Products.

development work to be performed during such period of the Development Phase, Xcyte may make payment to Dynal for such Dynabeads® M-450 CD3/CD28 T Product so ordered by Xcyte within twelve (12) months (instead of thirty (30) days) from the date of the invoices for such Product.

  
 4.4 Xcyte shall pay interest to Dynal on any overdue
payments under this Agreement at a rate of [*] per month overdue from the date due until payment. 
  
 4.5 Dynal reserves the right to alter the payment procedures set forth in this Agreement in the event that Xcyte has previously (within the
then-most recent three-month period) failed to conform to the payment provisions hereof and if and for so long as Dynal is reasonably concerned about Xcyte’s financial condition. Such alterations in payment terms shall be either a requirement
of an irrevocable, confirmed letter of credit or a requirement of cash prior to delivery. 
  
 4.6 Xcyte shall not require a delivery date of earlier than ninety (90) days after the date of receipt of an order for Products by Dynal. Orders by Xcyte for Products shall be sent to Dynal at P.O. Box 158,
Skøyen N-0212, Oslo, Norway, or as otherwise may be directed by Dynal from time to time. Dynal shall use its reasonable efforts to fill orders from Xcyte which are in accordance with this Section 4 by the delivery date requested by
Xcyte. Dynal shall acknowledge each Xcyte purchase order in writing and notify Xcyte of the estimated delivery date. Dynal shall promptly notify Xcyte if at any time Dynal has reason to be concerned that Dynal will not be able to fill any Xcyte
order on time or as estimated or agreed. 
  
 4.7 Xcyte
shall, starting at the thirtieth (30th) day following the end of the Development Phase and thereafter on a quarterly
basis (by March 31st, June 30th, September 30th, and December 31st) of each Year, provide to Dynal a forecast of Xcyte’s requirements for the Products for the ensuing twelve (12) month period for the Territory. The amount of Products specified
for the first quarter of such twelve (12) month period shall be binding on Xcyte, and Dynal shall supply, and Xcyte shall be required to take delivery and pay for such amount of the Products. All amounts specified for succeeding quarters of a twelve
(12) month period are considered a non-binding but good faith forecast.

 4.8 In addition to the forecasts provided pursuant to Section 4.7, Xcyte shall provide to Dynal good faith
non-binding three (3) Year forecasts for the Products for capacity and long-term manufacturing planning purposes. This three (3) Year forecast shall be provided by Xcyte to Dynal on or before the thirtieth (30th) day following the end of the
Development Phase, and thereafter by August 31st of each Year, covering the succeeding three-Year period. In the event that the manufacture of the volumes of Dynabeads® M-450 CD3/CD28 T indicated by such three-Year forecast would require Dynal to make any capital expansions (including
entering into any leases), the parties may meet to discuss in good faith how to proceed and whether Xcyte would be willing to commit to such forecasts if Dynal decides to make any capital expansion and/or enter into any leases (as Dynal shall decide
in its sole discretion). Subject to the provisions of Section 4.10, in no event shall Dynal be required to meet any such forecast for the Dynabeads® M-450 CD3/CD28 T (beyond the levels stated therein that would not require Dynal to make such capital expansions) nor to obtain such capital expansions
unless the parties agree in writing how to proceed and without Xcyte agreeing to purchase sufficient volumes of the Products and to amend this Agreement to increase the minimums set forth in Section 8.5. 
  
 4.9 All sales of Products to Xcyte shall be controlled by the terms
and conditions of this Agreement and the standard terms and conditions of the business forms of the parties shall not form part of the agreement of the parties. 
  

4.10 During the term of this Agreement, Dynal shall notwithstanding Section 4.8, fill any order (or series of orders) for any calendar
quarter which are in accordance with this Article 4 and that is (or are) not in excess of one hundred twenty five percent (125%) of the volumes specified for such calendar quarter in Xcyte’s most recent good faith quarterly estimate for such
calendar quarter (i.e., that was not a binding order for such calendar quarter under Section 4.7), and Dynal shall not be required to fill any order or series of orders that are for any calendar quarter in excess of one hundred twenty five
percent (125%) of the volumes specified for such calendar in Xcyte’s most recent good faith quarterly estimate for such calendar quarter. However, Dynal shall nevertheless exert commercially reasonable efforts to fill all Xcyte orders and to
supply all requested volumes to the extent the same may be done without extra cost to Dynal, and in doing so Dynal would not be in violation of any other agreement. 
  
 4.11 Notwithstanding anything contained herein, in no event shall Dynal be liable for any delay or failure to deliver
Products for reasons beyond the control of Dynal, provided, however, that Dynal shall notify Xcyte promptly of anticipated delays and shall use all commercially reasonable efforts to fill such orders as soon as possible. 
  
 4.12 If Dynal is not able to manufacture the Products in the
quantities ordered by Xcyte in accordance with the terms and conditions of this Agreement either itself or through its Affiliates, Dynal shall undertake to engage and qualify a Third Party contract manufacturer to manufacture those quantities of the
Products that Dynal and/or its Affiliates are unable to supply to Xcyte, for supply to Xcyte subject to and in accordance with the terms and conditions of this Agreement (including the terms and conditions of this Agreement relating to
Specifications, quality control and assurance, price, ordering, delivery, indemnities and warranties) and Xcyte shall continue to pay Dynal for the Products in accordance with Section 4. The parties recognize

 EXECUTION COPY 
  
 that use of such a Third Party contract manufacturer would constitute a “Major Change” as such term defined in
Attachment F, and that it will be handled in accordance with and shall be governed by the requirements in that Attachment. 
  
 4.13 All payments due to Dynal under this Agreement shall be paid in full, regardless of whether Xcyte or its Affiliates or their distributors or
licensees are required to withhold taxes, levies or other duties on payments made under this Agreement. If Xcyte is required to withhold taxes, levies or other duties on payments made under this Agreement, then Xcyte shall gross up such payments so
that Dynal receives the payment in full regardless of any withholdings, and if Dynal obtains any credit for the amount of the withholding, such amount shall be repaid by Dynal to Xcyte when it is received by Dynal. 
  
 SECTION 5: WARRANTY AND DISCLAIMER 
  
 5.1 Dynal warrants that the Products shall conform to the
Specifications upon delivery to Xcyte’s carrier, provided that in no event shall Dynal be responsible or liable for any failure of the Products to meet the Specifications as a result of defects in the Antibodies (other than any defect in the
Antibodies caused solely because of a failure of Dynal or its Affiliates to act in conformity with any applicable quality control guidelines provided to Dynal by Xcyte). Xcyte shall promptly inspect the Products upon receipt and in accordance with
any applicable quality control guidelines provided to Xcyte by Dynal, and shall promptly notify Dynal of any discovered failure of the Products to conform to the Specifications, but in no event later than thirty (30) days after Xcyte’s receipt
of the Products. Upon request by Dynal, Xcyte shall promptly return the non-conforming Products to Dynal. Upon verification that the Products failed to comply with the Specifications upon delivery to Xcyte’s carrier other than because of
defects in the Antibodies (other than any defect in the Antibodies caused solely because of a failure of Dynal or its Affiliates to act in conformity with any applicable quality control guidelines provided to Dynal by Xcyte), Xcyte shall receive, at
Dynal’s sole option, a credit, refund or replacement for such non-conforming Products. In the event that Dynal decides to replace such non-conforming Products with conforming Products, Dynal shall use reasonable commercial efforts to do so
within sixty (60) days of such confirmation by Dynal, and Dynal shall in such event bear the cost of delivery and risk of loss or damage to the replacement Products during delivery. Notwithstanding anything to the contrary contained in this
Agreement, Dynal shall not be responsible for any Products if such Products are removed from their original vials prior to inspection by Xcyte or are modified in any manner not in conformity with any applicable quality control guidelines provided to
Xcyte by Dynal, nor for any use or misuse or actions or inactions by any person or entity after delivery of the Products to Xcyte’s carrier. 
  
 THE FOREGOiNG WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, AND DYNAL EXPRESSLY DISCLAIMS ANY IMPLIED WARRANTIES INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. EXCEPT AS SET FORTH IN SECTION 10, XCYTE’S EXCLUSIVE REMEDY FOR ANY DEFECT IN THE PRODUCTS OR BREACH OF WARRANTY SHALL AT DYNAL’S OPTION BE
CREDIT, REFUND OR REPLACEMENT AS SET FORTH IN THIS SECTION 5.

 EXECUTION COPY 
  
 EXCEPT AS SET FORTH IN SECTION 10, IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR ANY SPECIAL, CONSEQUENTIAL OR INCIDENTAL DAMAGES BASED UPON
BREACH OF WARRANTY, BREACH OF CONTRACT, NEGLIGENCE, STRICT TORT OR ANY OTHER LEGAL THEORY. 
  
 SECTION 6: INTELLECTUAL PROPERTY 
  
 6.1    Except as provided in Section 6.2, ownership of any and all inventions or other proprietary rights (“Inventions”) developed in connection with activities under or performed in connection with this
Agreement, including in connection with development and acceptance testing of the Dynabeads® M-450 Epoxy T and the Dynabeads® M-450 CD3/CD28 T or during or in connection with work performed under the Work Plans, shall be determined by reference to United States laws pertaining to inventorship. For example, (a)
if Inventions is developed in connection with the development activities hereunder by one (1) or more employees or consultants of each party, it shall be jointly owned (“Joint Inventions”), and if one (1) or more claims included in an
issued Patent or pending Patent application which is filed in a patent office in the Territory claim such Joint Inventions such claims shall be jointly owned (“Joint Patent Rights”); and (b) if Inventions is developed in connection with
development activities hereunder solely by an employee or consultant of a party, it shall be solely owned by such party, and any Patent filed claiming such solely owned Inventions shall also be solely owned by such party. Each party shall ensure
that its employee and consultant inventors of Inventions developed in connection with this Agreement shall assign his/her interest in such Inventions to his/her respective party employer (e.g., Dynal or Xcyte, as the case may be), and such rights
shall therefore vest in the respective party employer to whom the inventor assigns his/her rights. The parties shall discuss and consult with each other in good faith as to the filing and prosecution of any joint patent applications covering Joint
Inventions, the maintenance of any ensuing Joint Patent Rights covering such Joint Inventions, and the enforcement, defense and protection of any such Joint Patent Rights. 
  
 6.2    Notwithstanding anything contained in this Agreement, including Section 6.1: (a) any
Inventions, including any know-how and data relating to any Dynabeads®, including the Dynabeads® M-450 and/or coupling to Dynabeads® and/or the coating of Dynabeads®, shall be owned solely by Dynal regardless of inventorship and Xcyte shall assign any and all such rights that Xcyte and/or its Affiliates or any of their agents may have in or to any such Inventions to Dynal, and such
rights shall therefore vest in Dynal; and (b) any Inventions, including any know-how and data relating to the Antibodies shall be owned solely by Xcyte regardless of inventorship and Dynal shall assign any and all such rights that Dynal and/or its
Affiliates or any of their agents may have in or to any such Inventions to Xcyte, and such rights shall therefore vest in Xcyte. 
  
 6.3    This Agreement contains no grants to either party under any intellectual property of the other party, except as expressly set
forth in this Agreement. 
  
 6.4    Xcyte
retains all right, title and interest in and to the Antibodies delivered or to be delivered to Dynal hereunder. Unless otherwise agreed by the parties, Dynal shall not at any time 
  

 - 12 - 








 EXECUTION COPY 
  
 during the term of this Agreement, divert or use any of the Antibodies for any other purpose or in support of any other product or service
than the Dynabeads® M-450 CD3/CD28 T to be
developed and manufactured hereunder solely for supply to Xcyte, and Dynal shall not authorize anyone else to do so. 
  
 SECTION 7: TRADEMARK, LABELING AND PACKAGING 
  
 7.1 Xcyte shall use the registered trademark “Dynabeads®” in the package inserts, labels and packaging and, to the extent appropriate, promotion and marketing materials, used in connection with
the sale of the Products or the performance of the treatments using the Products, and each such package insert, label and packing and promotion and marketing materials that uses such trademark shall state: “Dynabeads® is a registered trademark of Dynal A.S., Oslo Norway, licensed to Xcyte”
or equivalent language approved by Dynal. Xcyte and Dynal shall cooperate reasonably in the use by Xcyte of Dynal’s trademark, so that such use will be consistent with applicable regulations, including any concerning or affecting the
designation of Xcyte as the manufacturer. Subject to the terms and conditions of this Agreement, during the term of this Agreement, Dynal hereby grants to Xcyte a non-exclusive license to use the Dynabeads® trademark to such limited extent. The registered trademark “Dynabeads®” is and shall remain the sole and exclusive
property of Dynal and all goodwill arising from the use of the Dynabeads® trademark shall enure to the benefit of Dynal. If necessary in any market to maintain Dynal’s rights in Dynal’s trademarks, Xcyte shall enter into a reasonable separate royalty-free license or registered user
agreement regulating its use of the Dynal trademarks. Approval of such material by Dynal shall not be unreasonably withheld. Approval shall be deemed given in the event that Dynal does not otherwise so notify Xcyte within twenty-one (21) days after
receipt of such material from Xcyte. During any periods in which Xcyte is so using any Dynal trademark(s), Xcyte shall periodically and upon reasonable request, provide Dynal with samples of any products and packages that bear, or that have been
associated with, copies of all product literature, promotional material, advertising, product inserts, labeling and packaging and other printed materials that use, the “Dynabeads®” trademark, in order that Dynal may monitor the quality of products associated
with such trademark(s). 
  
 7.2 The Products shall be labeled and
packaged for delivery to Xcyte as provided in Attachment F.

disclosure otherwise reasonably put the recipient on notice that the information or materials are treated as confidential or which receiving party should reasonably know should be treated as confidential. The parties agree: 
  
 (i) not to use such Confidential Information for any purpose other than for
the purpose of this Agreement or as may otherwise be agreed by the parties in writing; 
  
 (ii) to use the same degree of care to maintain such Confidential Information in confidence as it applies to confidential information of its own of the same type, but in no event less than a reasonable standard of

 (iv) Information that, after disclosure, can be demonstrated by the receiving party by credible evidence to have been
subsequently provided to the receiving party by a Third Party having the right to disclose such information and without obligations of confidentiality if the receiving party reasonably believes such disclosure does not violate any obligations of the
Third Party to the disclosing party. 
  
 (v) Information that has
been independently developed without the benefit of any reference to any disclosure hereunder from the other party. 
  
 (vi) Information that is required to be disclosed by law or regulation, provided that the party required to make such disclosure shall, to the extent

documents that contain any Confidential Information) received from the disclosing party if the retention of the same is necessary for regulatory purposes or is otherwise required by law or regulation, and in any event the receiving party may retain
one (1) copy of Confidential Information received from the disclosing party for archival purposes.

 12.2 Any dispute arising from or in connection with this Agreement during the

parties to arbitrate any and all claims and disputes under this Agreement as provided in this Section 12.3, and the results, determination, finding, judgment and/or award rendered through such arbitration, shall be final and binding on the
parties thereto and may be specifically enforced by legal proceedings in a court having jurisdiction over the party in question. Arbitration proceedings under this Agreement shall be conducted under the auspices of the International Arbitration
Rules of the American Arbitration Association (the “AAA”) in New York. Dynal shall appoint one (1) arbitrator, and Xcyte one (1) arbitrator, within a term of thirty (30) days from the date arbitration is required or invoked by the parties,
and the two (2) arbitrators so appointed shall appoint the third arbitrator within a term of thirty (30) days from the date on which the later of the two (2) arbitrators have been selected, all in accordance with the rules of the AAA. If either
party fails to select its arbitrator within the term mentioned above, or in the event that the two (2) selected arbitrators are unable or unwilling to select a third arbitrator within thirty (30) days, one shall be appointed in accordance with the
rules of the AAA, and the three (3) arbitrators so selected shall constitute the arbitration panel for purposes of the dispute. Unless agreed otherwise by the parties, the parties shall have thirty (30) days thereafter to submit their position to
the arbitrators, and the arbitrators shall be instructed and required to render their decision within thirty (30) days following completion of the arbitration. In any arbitration, the prevailing party shall be entitled to reimbursement of its
