 ARTICLE 2 

XOMA GRANT OF RIGHTS TO AFFIMED 

2.1. Research License. XOMA hereby grants to AFFIMED a worldwide, fully paid-up, royalty free, non-exclusive, non-transferable license,
on its own behalf and on behalf of an AFFIMED Collaborator, and without the right to sublicense, under the XOMA Patent Rights and the XOMA Know-How to make and use Licensed Materials to conduct Research, including Antibody Phage Display (the
“Research License”). For the sake of clarity, the Research License is personal to AFFIMED and is to be used on behalf of any AFFIMED Collaborator only in respect of or in connection with the activities that such AFFIMED Collaborator
is engaged in that are the basis for meeting the definition of AFFIMED Collaborator and not any other activities. It is understood between the Parties that the license granted by this Section 2.1 is a “research only” license and that,
unless and until the Option is exercised in accordance with Section 2.5(a), AFFIMED shall have no rights to commercialize, either directly or indirectly, any immunoglobulin or Licensed Immunoglobulin Information, arising from the activities
subject to this license grant. 
 2.2. XOMA Transfer to AFFIMED. Within thirty (30) days of the Effective Date, XOMA shall
transfer to AFFIMED, at a mutually agreed place and time, the materials identified on Schedule 2.2. For the avoidance of doubt, such materials shall constitute XOMA Know-How. Technology is included in the initial consideration to XOMA under
this Agreement and includes up to two person-days of XOMA scientific staff time at XOMA’s facilities for up to two (2) AFFIMED employees within 9 months from the Effective Date (which period may be extended by mutual consent of the
parties, which consent shall not be unreasonably withheld). Thereafter, AFFIMED will be able to consult with XOMA scientific staff at $1,500/person-day (based on an eight hour day) beyond the two person-days. 

2.3. No Implied Rights. Only the rights and licenses granted pursuant to the express terms of this Agreement shall be of any legal
force or effect. No license or other rights shall be deemed to have been granted to AFFIMED or an AFFIMED Collaborator other than as expressly provided for in this Agreement. For the avoidance of doubt, the grants of rights made pursuant to
Section 2.1 and, upon exercise of the Option, Section 2.5, do not include, and expressly exclude, the following: 
  

	 	(a)	any right or license to engage in any activities on behalf of or in collaboration with any Third Party, other than an AFFIMED Collaborator; 


  
 -9- 









	 	(b)	except upon proper exercise of the Option with respect to each Licensed Immunoglobulin, any right or license to make or have made any amount, other than Research Quantities, of a Licensed Immunoglobulin by practicing
the XOMA Patent Rights or the XOMA Know-How; 

  

	 	(c)	any release or right to release any Third Party, including an AFFIMED Collaborator, from any claim of infringement under the XOMA Patent Rights or misappropriation of the XOMA Know-How;

	 	(e)	any right or license under the XOMA Patent Rights or XOMA Know-How to sell, lease, license, transfer or dispose of the ownership or possession to a Third Party of any composition of matter or article of manufacture
suitable for the conduct of Antibody Evolution or Antibody Phage Display; and/or 

  

	 	(f)	any right or license to cause any Third Party to use Antibody Phage Display Materials to identify, select, characterize, study or test a polypeptide, including but not limited to an Immunoglobulin. 


2.4. Transfer Restrictions. 

(a) AFFIMED shall not (i) undertake any Research activities, including any Antibody Phage Display, on behalf of a Third Party or
(ii) Dispose of a Licensed Immunoglobulin, Licensed Immunoglobulin Information or any Immunoglobulin arising out of the practice of any method within the scope of the XOMA Patent Rights (“Transferred Materials”) to any Third
Party until (in the case of either clause (i) or clause (ii)) such time as it has provided to such Third Party the redacted copy of this Agreement referred to in Section 7.2 and the form of notice set out at Schedule 2.4. 

(b) AFFIMED shall enter into a written arrangement with any Third Party with respect to any activities as to which it or such Third Party does
or intends to claim the benefits of any of the licenses or other grants provided for in this Article 2, and such written arrangement shall contain provisions (i) pursuant to which the recipient of any Transferred Materials agrees to abide by
each of the limitations, restrictions and other obligations provided for by this Agreement, including without limitation the restrictions on use of Transferred Materials for purposes other than Research and the obligations of Section 2.5(b);

executes a written agreement in which it undertakes all of the obligations applied to the transferring party. XOMA shall be, and the agreements subject to this Section 2.4 shall provide that
XOMA shall be, an intended third party beneficiary with respect to the foregoing provisions. 
 2.5. License Option. 

(a) So long as the provisions of Section 2.5(b) are complied with and AFFIMED and, as applicable, any AFFIMED Collaborator, is not
otherwise in breach of any material provision of this Agreement, upon ***** prior written notice, on an Immunoglobulin by Immunoglobulin basis, XOMA hereby agrees to grant (the “Option”) a worldwide, non-exclusive, non-transferable
license to AFFIMED, on its own behalf and on behalf of an AFFIMED Collaborator, under the XOMA Patent Rights and the XOMA Know-How in the AFFIMED Field to: 
  

	 	(i)	make or have made (in a prokaryote and without use of a discistronic construct), use, sell, offer to sell, import and otherwise commercialize those Licensed Immunoglobulins discovered, isolated or optimized under the
Research License and as to which AFFIMED or the AFFIMED Collaborator pays the amounts, including royalties on Net Sales, due under Article 3; and/or 

  

	 	(ii)	to make in E. Coli, solely on its own behalf, clinical and commercial supplies of any Immunoglobulin discovered or isolated exclusively by AFFIMED or by AFFIMED on behalf of an AFFIMED Collaborator and as to
which AFFIMED pays the amounts, including royalties on Net Sales, due under Article 3. 

 XOMA shall not be obligated to grant the license
provided for in this Section 2.5(a) unless the other provisions of this Agreement, including Section 2.5(b), are complied with. 

(b) For each Licensed Immunoglobulin as to which AFFIMED wishes to obtain a license pursuant to Section 2.5(a), AFFIMED shall provide to
XOMA a written notice which identifies the specific Immunoglobulin for which AFFIMED seeks such a license, the target to which such Immunoglobulin binds, a designation as to whether such Immunoglobulin was discovered or isolated pursuant to the
Research License, a written certification that AFFIMED or as applicable an AFFIMED Collaborator, for each Licensed Immunoglobulin, has complied with all of the provisions of this Agreement and a notification as to whether AFFIMED seeks a license
pursuant to Section 2.5(a)(i), Section 2.5(a)(ii) or both. Upon receipt of such written notice, XOMA shall, pursuant to its then most current standard non-economic terms, grant the applicable license, unless (i) such Immunoglobulin or
target is the subject of an exclusive license granted by XOMA to a Third Party or (ii) XOMA has contemporaneous written proof of a bona fide development program with respect to any Immunoglobulin binding to the same target as the Immunoglobulin
as to which the request for license grant has been made. 

  
 -11- 








 (c) Upon the successful exercise of an Option to an Immunoglobulin, for so long as the applicable
royalty and other payments are made, XOMA covenants that it shall not initiate or permit any Third Party over whom it has control to initiate or assist in any way in the initiation or prosecution of any action asserting a claim of infringement under
the XOMA Patent Rights or misappropriation of the XOMA Know-How against AFFIMED or any AFFIMED Collaborator to the extent reasonably necessary to permit the authorized making, having made, use, sale, offer for sale or commercialization of any
Licensed Immunoglobulin subject to a grant under Section 2.5(a)(i) and the making and having made of any Immunoglobulin subject to a grant under Section 2.5(a)(ii). The covenant not to sue provided by this Section 2.5(c): 

 

	 	(i)	shall become void and without effect as to any entity or person who claims its benefit but fails to materially discharge or comply with any term of its written agreement with AFFIMED provided for in Section 2.4(b);


  

	 	(ii)	is personal to AFFIMED and any such AFFIMED Collaborator and cannot be assigned or transferred; 

  

	 	(iii)	as to any AFFIMED Collaborator, does not extend to making, using, selling, having made or importing Antibody Phage Display Materials or any compositions of matter or articles of manufacture suitable for Antibody Phage
Display; and 

  

	 	(iv)	does not constitute a release or waiver of past, present or future infringement of the XOMA Patent Rights or misappropriation of the XOMA Know-How by AFFIMED or any Third Party, including, without limitation, any
AFFIMED Collaborator acting outside of the scope of the written agreement with AFFIMED provided for in Section 2.4(b).

such Immunoglobulin to XOMA for a license pursuant to this Section 2.5. 
 2.6. Third Party Variable Domains. (a) From time
to time, but no more often than once per quarter, AFFIMED may, on its own behalf or on behalf of a Third Party who otherwise qualifies as an AFFIMED Collaborator and who will be an AFFIMED Collaborator if the other provisions of this
Section 2.6 are met, request in writing that XOMA permit AFFIMED to format a variable domain not discovered by AFFIMED into a Tandab or a Flexibody and, as applicable, exercise its Option rights pursuant to Section 2.5(a)(i) and (ii). Such
writing (the “In-License Request”) shall specify: (i) the potential AFFIMED Collaborator and any Third Party with a financial interest in the variable domains or the proposed AFFIMED Product; (ii) the variable domains;
(iii) the target as to which such variable domains are directed; (iv) whether the Option request extends to the rights provided for by Sections 2.5(a)(i), 2.5(a)(ii) or both; (v) the format such variable domains shall be
converted into (Tandab or Flexibody); and (vi) a statement as to whether, to the knowledge of AFFIMED after diligent investigation, such variable domains were discovered, identified, characterized, optimized and/or altered using the


  
 -12- 








 
XOMA Patent Rights or bacterial expression, including without limitation via Antibody Phage Display. Upon such request, and until the end of Phase II (or equivalent) clinical trials, such Tandab
or Flexibody shall be deemed to be an “AFFIMED Product” under this Agreement, provided, however, that if no In-License Request is made prior to initiation of Phase II or if a license is not subsequently consummated, then any status
as an AFFIMED Product shall, retroactively, be cancelled and the Tandab or Flexibody will be deemed as to have never been licensed under this Agreement. 

(b) Within ***** of the receipt of the In-License Request, XOMA, pursuant to the same conditions as Section 2.5(b), shall, in writing,
indicate whether each such proposed AFFIMED Product is accepted to be a Licensed Immunoglobulin. For each such proposed AFFIMED Product accepted as a Licensed Immunoglobulin, the following conditions shall apply: (i) XOMA, AFFIMED and the Third
Party must agree to the form of and execute a written license agreement under which XOMA shall grant, pursuant to its then most current non-economic terms, the applicable license; (ii) AFFIMED and the Third Party, if applicable, must negotiate
in good faith for and pay cash consideration to XOMA to obtain a release for any past infringement of the XOMA Patent Rights by such Third Party; and (iii) such license shall, as applicable, contain licenses or grants to XOMA and any XOMA
Development Partner or XOMA Licensee under those rights as may be under the control of or sublicenseable from such Third Party in a form equivalent to the license grant and rights given by AFFIMED to XOMA pursuant to Article 4 of this Agreement.

 (c) AFFIMED’s rights under this Section 2.6 shall apply to no more than five (5) different Tandabs or Flexibodies. 

2.7. XOMA Authorized Site. AFFIMED may “have made” Licensed Immunoglobulins or Immunoglobulins subject to

containing all of the applicable provisions of this Agreement and shall be for the sole benefit of AFFIMED. XOMA shall be provided a reasonable opportunity prior to execution of any such agreement to review a redacted version of such agreement that
is sufficient to confirm the foregoing obligations, and AFFIMED shall give due consideration to any comments of XOMA thereon. Prior to permitting or initiating any activity at a XOMA Authorized Site in the AFFIMED Field, AFFIMED covenants that such
XOMA Authorized Site shall (i) agree in advance in writing to be bound for the benefit of XOMA by all of the provisions of this Agreement; (ii) agree to implement such customary and usual safeguards as may be necessary to insure that the
XOMA Know-How is accessed and utilized on a “need to know” basis only; and (iii) agree that such XOMA Authorized Site shall undertake the activities solely on behalf of AFFIMED and as a result of such activities shall not claim any
license or right under the XOMA Patent Rights or XOMA Know-How for the benefit of itself or any other Third Party. AFFIMED shall remain fully and primarily liable for all actions of, or failures to act by, such XOMA Authorized Site in connection
therewith and agrees to hold XOMA harmless with respect thereto without qualification. For the avoidance of doubt, AFFIMED acknowledges that no such delegation of rights shall relieve AFFIMED

 XOMA LIBRARY PROJECT

 5.1. AFFIMED Library Construction. 

(a) Under the terms and conditions of this Agreement and as described in Schedule 5.1, AFFIMED agrees to create (each a “XOMA
Library Project”) ***** libraries of antibody genes, and expression vectors encoding such antibody genes, derived from ***** samples (each a “XOMA Library”). At XOMA’s option and upon its written request, AFFIMED
shall create each XOMA Library in accordance with XOMA’s written instructions and specifications (each a “XOMA Library Specification”) by applying any technology then under AFFIMED’s control. Each XOMA Library
Specification shall provide reasonable detail setting forth the nature and characteristics of the XOMA Library to be constructed. For the avoidance of doubt, at XOMA’s request, the XOMA Library may be encoded in expression vectors, including
bacteriophage or phagemid display vectors of XOMA’s selection. Within thirty (30) days of the request by XOMA, at AFFIMED’s request, XOMA shall provide such written technical and other information that is reasonably necessary for
AFFIMED to assess the technical requirements for construction of the XOMA Library. 
 (b) Within sixty (60) days of the provision of
the XOMA Specification, AFFIMED shall provide in writing the anticipated timeline and a good faith estimate of the total Direct AFFIMED Costs required for construction of the applicable XOMA Library. Within thirty (30) days of the receipt of
such timeline and cost estimate, XOMA shall comment on and either approve or, after good faith negotiations with AFFIMED, modify and approve such timeline and cost estimate. At any time prior to the commencement of a XOMA Library Project, XOMA may
cancel such XOMA Library Project and such cancelled XOMA Library Project shall not be counted with respect to the other provisions of this Article 5. AFFIMED shall use commercially reasonable and diligent efforts to commence and complete the
activities necessary for the completion of the creation and transfer to XOMA of each XOMA Library with the same level of skill, resources and personnel as it would apply to a similar project undertaken on its own behalf. With respect to each XOMA
Library Project, AFFIMED shall not discriminate against the XOMA Library Project in favor of any Third Party or any of AFFIMED’s internal projects with respect to the application of any techniques or know-how or access to technology or skilled
personnel. For each calendar quarter while a XOMA Library Project is being conducted, AFFIMED, with the consultation and approval of XOMA, shall, as necessary, update and revise the cost estimates and timelines associated therewith. AFFIMED shall
represent and warrant that its activities, the materials and methods used by AFFIMED and any Project Materials provided to XOMA shall be free of claims of patent infringement or misappropriation by any Third Party.

it relates to any XOMA Library and any Project Materials relating thereto and with the exception of the AFFIMED Technology (other than as required to make, use, sell, offer for sale, import or export Project Materials), AFFIMED shall grant,
sublicense or extend the benefit to XOMA of any rights, licenses or other rights to any intellectual property, including patents or patent rights, under the control of AFFIMED or as to which AFFIMED has the power to make such grant, provided,
however, that in the event such grant, sublicense or extension of benefit requires the payments of any amount by XOMA or AFFIMED, at XOMA’s option, XOMA may either pay and hold AFFIMED harmless from such payments or waive such grant. The
license grant of this Section 5.4(c) excludes (i) the conduct of a Commercial Antibody Phage Display Business or a Commercial Evolution Business, and (ii) the conduct of any phage display services or other Immunoglobulin discovery
activities for any Third Party except a XOMA Licensee. 
 5.5. Covenant Not To Sue. AFFIMED covenants that it shall not assert
any claims or permit any Third Party over whom it has control to initiate or assist in any way in the initiation or prosecution of any action asserting a claim of infringement under the AFFIMED Patent Rights against XOMA or any XOMA Licensee or
misappropriation of the Project Materials against XOMA to the extent such claims arise out of (a) use of the Project Materials by XOMA as permitted under the provisions of this Agreement or (b) the discovery, isolation, optimization or
development by XOMA or a XOMA Licensee, or the manufacture, use, offer for use, sale, offer for sale, importation and exportation, of any Immunoglobulin or product containing or comprising an Immunoglobulin which was discovered under conditions
which but for this license would constitute misappropriation of any AFFIMED Technology or infringement of the AFFIMED Patent Rights.

TERM AND TERMINATION 

9.1. Term. Subject to Sections 9.4 and 9.5 hereof, the term of this Agreement will commence on the Effective Date and
(a) with regard to the license and other rights granted to AFFIMED and any AFFIMED Collaborators by XOMA pursuant to Article 2, this Agreement shall remain in full force and effect until the last to expire of the XOMA Patent Rights or the tenth
anniversary of the First Commercial Sale of the last Immunoglobulin subject to Section 2.5(b) to be launched, whichever is later, unless earlier terminated by XOMA pursuant to Section 9.2 or 9.3; and (b) with regard to the license and

upon any material breach by XOMA or AFFIMED, as the case may be, of any material obligation or condition of the Agreement, in either case effective ***** after giving notice to the breaching party of such termination in the case of a payment breach
and ***** after giving written notice to the breaching party of such termination in the case of any other breach, which notice shall describe such breach in reasonable detail. The foregoing notwithstanding, if such breach is cured or shown to be
non-existent within the aforesaid ***** or ***** period, the notice shall be deemed automatically withdrawn and of no effect and the notifying party shall provide written notice to the breaching party of the withdrawal. A termination of the

from the other party (except that each party may retain one copy for its files solely for the purpose of determining its: rights and obligations hereunder).

10.3. Certain Changes in Control. (a) Notwithstanding any other provision of this Agreement to the contrary, solely at XOMA’s
option, unless the provisions of Section 10.3(b) are met, the license and other rights granted to AFFIMED and any AFFIMED Collaborators pursuant to Article 2 shall automatically terminate, in whole or in part, without further action by the

Phage by AFFIMED. 
 (b) The provisions of Section 10.3(a) shall, for a single Change of Control transaction not apply to the
purchase of AFFIMED or all of the antibody discovery assets used for Antibody Phage Display by AFFIMED to a Third Party if (i) the acquiring Third Party has a market capitalization of less than ***** (as determined either by the acquirer’s
share price on the relevant stock exchange thirty (30) days prior to the Change of Control becoming effective or (when the acquiring Third Party is not listed) by the value as determined in the acquirer’s last financing round according to

or decreased) by multiplying it by a fraction (expressed as a percentage), the numerator of which is the average NASDAQ Composite Index for the thirty (30) days beginning sixty (60) days, and ending thirty (30) days, prior to the
Change of Control becoming effective and the denominator of which is the average NASDAQ Composite Index for the thirty (30) days after the Effective Date; (ii) such acquiring Third Party either is not engaged in a Commercial Antibody Phage
Display Business or Commercial Antibody Evolution Business or is engaged in a Commercial Antibody Phage Display Business or Commercial Antibody Evolution Business that has been licensed by XOMA (in which case XOMA shall elect which license
continues); (iii) such acquiring Third Party quitclaims any right to extend this Agreement to any Immunoglobulin discovered, isolated, characterized or optimized by its or any other Third Party prior to the effective date of the Change of
Control; and (iv) such acquiring Third Party agrees to be bound by all the applicable provisions of this Agreement on a going forward basis. 

10.4. Waiver. No waiver of any rights shall be effective unless consented to in writing by the party to be charged and the waiver of
any breach or default shall not constitute a waiver of any other right hereunder or any subsequent breach or default. 

  
 -28- 








 10.5. Severability. In the event that any provisions of this Agreement are determined to
be invalid or unenforceable by a court of competent jurisdiction, the remainder of the Agreement shall remain in full force and effect without said provision.

Agreement, or (b) if not delivered as provided under clause (a) above, upon such other party’s request following the rejection of this Agreement by or on behalf of the party subject to such bankruptcy proceeding. If a party has taken
possession of all applicable embodiments of the intellectual property of the other party pursuant to this section 10.9 and the trustee in bankruptcy of the other party does not reject this Agreement, the party in possession of such intellectual
property shall return such embodiments upon request. If a party seeks or involuntarily is placed under Title XI and the trustee rejects this Agreement as contemplated under 11 U.S.C. 365(n)(l), the other party hereby elects, pursuant to

Any controversy or claim between the parties to this Agreement (other than any dispute which arises out of or relates to infringement, validity and/or enforceability of the XOMA Patent Rights or the AFFIMED Patent Rights) arising out of or relating
to this Agreement or the breach thereof shall be finally determined by arbitration in New York, in accordance with the International Arbitration Rules of the International Centre for Dispute Resolution (“ICDR”) or other rules agreed

procedures for arbitrator selection of the ICDR. 

  
 -30- 








 (b) The parties acknowledge that this Agreement evidences a transaction involving interstate

involved in the dispute, final and non-appealable. Judgment upon the award rendered by the panel may be entered in any court having jurisdiction thereof. 

(d) Except as provided under the United States Arbitration Act and with respect to the infringement, validity and/or enforceability of the
XOMA Patent Rights or the AFFIMED Patent Rights, no action at law or in equity based upon any dispute that is subject to arbitration under this Section 10.13 shall be instituted. 

(e) The arbitral panel shall have the authority to award, in its discretion, part or all the expenses of any arbitration pursuant to this
Section 10.13, including fees and expenses of the prevailing party’s attorneys, fees and expenses of the arbitrators, and fees and expenses of any witness or the cost of any proof produced at the request of the arbitrators, to the
prevailing party.

an original, but all of which together shall constitute one and the same instrument.

Form of Notice 
 XOMA owns a number
of patents covering various aspects of bacterial antibody expression and phage display. 
 XOMA has licensed these patents on a non-exclusive basis to
AFFIMED. 
 Under the license agreement with XOMA: 
  

	•	 	AFFIMED cannot provide evolution or phage display services or transfer related Immunoglobulin information to you without first showing you a redacted copy of its license from XOMA and this notice. 


 

	•	 	If you and AFFIMED enter into a written agreement by which you become a “AFFIMED Collaborator,” then you will be permitted to use AFFIMED evolution or phage display services and related Immunoglobulin and
information to research, develop and commercialize antibody Immunoglobulin. 

  

	•	 	Collaborators do not, however, have either the right to (a) produce commercial quantities of such antibodies using XOMA’s patented technology or (b) commercialize any results of research conducted by
AFFIMED. Rather, AFFIMED has the right to make Research quantities of antibodies using the XOMA patent rights. AFFIMED has the right to obtain licenses from XOMA on pre-negotiated terms, but subject to certain conditions. 


 

	•	 	Therefore, if you and AFFIMED enter into a written agreement, that agreement must contain certain provisions specified in the license agreement with XOMA, including: 


 

	 	•	 	Terms pursuant to which you, as the recipient of any transferred materials, would agree to abide by each of the limitations, restrictions and other obligations provided for by the license agreement with XOMA, including,

2.3 No Implied Rights. Only the rights and licenses granted pursuant to the express terms of this Agreement shall be of any legal force
or effect. No license or other rights shall be deemed to have been granted to AFFIMED or an AFFIMED Collaborator other than as expressly provided for in this Agreement. For the avoidance of doubt, the grants of rights made pursuant to
Section 2.1 and, upon exercise of the Option, Section 2.5, do not include, and expressly exclude, the following:

	 	(c)	any release or right to release any Third Party, including an AFFIMED Collaborator, from any claim of infringement under the XOMA Patent Rights or misappropriation of the XOMA Know-How; 


 

	 	(d)	does not constitute a release or waiver of past, present or future infringement of the XOMA Patent Rights or misappropriation of the XOMA Know-How by AFFIMED or any Third Party; 


 

	 	(e)	any right or license under the XOMA Patent Rights or XOMA Know-How to sell, lease, license, transfer or dispose of the ownership or possession to a Third Party of any composition of matter or article of manufacture

	 	(f)	any right or license to cause any Third Party to use Antibody Phage Display Materials to identify, select, characterize, study or test a polypeptide, including but not limited to an Immunoglobulin. 


2.4 Transfer Restrictions. 

(a) AFFIMED shall not (i) undertake any Research activities, including any Antibody Phage Display, on behalf of a Third Party or
(ii) Dispose of a Licensed Immunoglobulin, Licensed Immunoglobulin Information or any Immunoglobulin arising out of the practice of any method within the scope of the XOMA Patent Rights (“Transferred Materials”) to any Third
Party until (in the case of either clause (i) or clause (ii)) such time as it has provided to such Third Party the redacted copy of this Agreement referred to in Section 7.2 and the form of notice set out at Schedule 2.4. 

(b) AFFIMED shall enter into a written arrangement with any Third Party with respect to any activities as to which it or such Third Party does
or intends to claim the benefits of any of the licenses or other grants provided for in this Article 2, and such written arrangement shall contain provisions (i) pursuant to which the recipient of any Transferred Materials agrees to abide by
each of the limitations, restrictions and other obligations provided for by this Agreement, including without limitation the restrictions on use of Transferred Materials for purposes other than Research and the obligations of Section 2.5(b);
(ii) implementing a covenant not to use Transferred Materials for any purpose other than for Research purposes otherwise authorized by this Agreement; (iii) providing that the “first sale” doctrine does not apply to any
Disposition; and (iv) permitting an AFFIMED Collaborator to further Dispose of Transferred Materials only to a Third Party who otherwise meets the definition of an AFFIMED Collaborator and who executes a written agreement in which it undertakes
all of the obligations applied to the transferring party. XOMA shall be, and the agreements subject to this Section 2.4 shall provide that XOMA shall be, an intended third party beneficiary with respect to the foregoing provisions.

 2.5 License Option. 

(a) So long as the provisions of Section 2.5(b) are complied with and AFFIMED and, as applicable, any AFFIMED Collaborator, is not
otherwise in breach of any material provision of this Agreement, upon ***** prior written notice, on an Immunoglobulin by Immunoglobulin basis, XOMA hereby agrees to grant (the “Option”) a worldwide, non-exclusive, nontransferable
license to AFFIMED, on its own behalf and on behalf of an AFFIMED Collaborator, under the XOMA Patent Rights and the XOMA Know-How in the AFFIMED Field to: 
  

	 	(i)	make or have made (in a prokaryote and without use of a discistronic construct), use, sell, offer to sell, import and otherwise commercialize those Licensed Immunoglobulins discovered, isolated or optimized under the
Research License and as to which AFFIMED or the AFFIMED Collaborator pays the amounts, including royalties on Net Sales, due under Article 3; and/or 

  

	 	(ii)	to make in E. Coli, solely on its own behalf, clinical and commercial supplies of any Immunoglobulin discovered or isolated exclusively by AFFIMED or by AFFIMED on behalf of an AFFIMED Collaborator and as to
which AFFIMED pays the amounts, including royalties on Net Sales, due under Article 3. 

 XOMA shall not be obligated to grant the license
provided for in this Section 2.5(a) unless the other provisions of this Agreement, including Section 2.5(b), are complied with. 

(b) For each Licensed Immunoglobulin as to which AFFIMED wishes to obtain a license pursuant to Section 2.5(a), AFFIMED shall provide to
XOMA a written notice which identifies the specific Immunoglobulin for which AFFIMED seeks such a license, the target to which such Immunoglobulin binds, a designation as to whether such Immunoglobulin was discovered or isolated pursuant to the
Research License, a written certification that AFFIMED or as applicable an AFFIMED Collaborator, for each Licensed Immunoglobulin, has complied with all of the provisions of this Agreement and a notification as to whether AFFIMED seeks a license
pursuant to Section 2.5(a)(i), Section 2.5(a)(ii) or both. Upon receipt of such written notice, XOMA shall, pursuant to its then most current standard non-economic terms, grant the applicable license, unless (i) such Immunoglobulin or
target is the subject of an exclusive license granted by XOMA to a Third Party or (ii) XOMA has contemporaneous written proof of a bona fide development program with respect to any Immunoglobulin binding to the same target as the Immunoglobulin
as to which the request for license grant has been made. 
 (c) Upon the successful exercise of an Option to an Immunoglobulin, for so long
as the applicable royalty and other payments are made, XOMA covenants that it shall not initiate or permit any Third Party over whom it has control to initiate or assist in any way in the initiation or prosecution of any action asserting a claim of
infringement under the XOMA Patent Rights or misappropriation of the XOMA Know-How against AFFIMED or any AFFIMED Collaborator to the extent reasonably necessary to permit the authorized making, having made, use, sale, offer for sale or
commercialization of any 

  
 -10- 








 
Licensed Immunoglobulin subject to a grant under Section 2.5(a){i) and the making and having made of any Immunoglobulin subject to a grant under Section 2.5(a)(ii). The covenant not to
sue provided by this Section 2.5(c): 
  

	 	(i)	shall become void and without effect as to any entity or person who claims its benefit but fails to materially discharge or comply with any term of its written agreement with AFFIMED provided for in Section 2.4(b);


  

	 	(ii)	is personal to AFFIMED and any such AFFIMED Collaborator and cannot be assigned or transferred; 

  

	 	(iii)	as to any AFFIMED Collaborator, does not extend to making, using, selling, having made or importing Antibody Phage Display Materials or any compositions of matter or articles of manufacture suitable for Antibody Phage
Display; and 

  

	 	(iv)	does not constitute a release or waiver of past, present or future infringement of the XOMA Patent Rights or misappropriation of the XOMA Know-How by AFFIMED or any Third Party, including, without limitation, any
AFFIMED Collaborator acting outside of the scope of the written agreement with AFFIMED provided for in Section 2.4(b). 


(d) AFFIMED covenants not to commercialize, license or develop any Immunoglobulin discovered under the Research License without submitting
such Immunoglobulin to XOMA for a license pursuant to this Section 2.5. 
 2.6 Third Party Variable Domains. (a) From time
to time, but no more often than once per quarter, AFFIMED may, on its own behalf or on behalf of a Third Party who otherwise qualifies as an AFFIMED Collaborator and who will be an AFFIMED Collaborator if the other provisions of this
Section 2.6 are met, request in writing that XOMA permit AFFIMED to format a variable domain not discovered by AFFIMED into a Tandab or a Flexibody and, as applicable, exercise its Option rights pursuant to Section 2.5(a)(i) and (ii). Such
writing (the “In-License Request”) shall specify: (i) the potential AFFIMED Collaborator and any Third Party with a financial interest in the variable domains or the proposed AFFIMED Product; (ii) the variable domains;
(iii) the target as to which such variable domains are directed; (iv) whether the Option request extends to the rights provided for by Sections 2.5(a)(i), 2.5(a)(ii) or both; (v) the format such variable domains shall be converted
into (Tandab or Flexibody); and (vi) a statement as to whether, to the knowledge of AFFIMED after diligent investigation, such variable domains were discovered, identified, characterized, optimized and/or altered using the XOMA Patent Rights or
bacterial expression, including without limitation via Antibody Phage Display. Upon such request, and until the end of Phase II (or equivalent) clinical trials, such Tandab or Flexibody shall be deemed to be an “AFFIMED Product” under this
Agreement, provided, however, that if no In-License Request is made prior to initiation of Phase II or if a license is not subsequently consummated, then any status as an AFFIMED Product shall, retroactively, be cancelled and the Tandab or
Flexibody will be deemed as to have never been licensed under this Agreement. 

  
 -11- 








 (b) Within ***** of the receipt of the In-License Request, XOMA, pursuant to the same conditions
as Section 2.5(b), shall, in writing, indicate whether each such proposed AFFIMED Product is accepted to be a Licensed Immunoglobulin. For each such proposed AFFIMED Product accepted as a Licensed Immunoglobulin, the following conditions shall
apply: (i) XOMA, AFFIMED and the Third Party must agree to the form of and execute a written license agreement under which XOMA shall grant, pursuant to its then most current noneconomic terms, the applicable license; (ii) AFFIMED and the
Third Party, if applicable, must negotiate in good faith for and pay cash consideration to XOMA to obtain a release for any past infringement of the XOMA Patent Rights by such Third Party; and (iii) such license shall, as applicable, contain
licenses or grants to XOMA and any XOMA Development Partner or XOMA Licensee under those rights as may be under the control of or sublicenseable from such Third Party in a form equivalent to the license grant and rights given by AFFIMED to XOMA
pursuant to Article 4 of this Agreement. 
 (c) AFFIMED’s rights under this Section 2.6 shall apply to no more than five
(5) different Tandabs or Flexibodies. 
 2.7 XOMA Authorized Site. AFFIMED may “have made” Licensed Immunoglobulins or
Immunoglobulins subject to Section 2.5(a)(ii) under the XOMA Patent Rights and the XOMA Know-How in the AFFIMED Field at a XOMA Authorized Site. All activities at a XOMA Authorized Site in the AFFIMED Field shall be pursuant to a contract
manufacturing agreement containing all of the applicable provisions of this Agreement and shall be for the sole benefit of AFFIMED. XOMA shall be provided a reasonable opportunity prior to execution of any such agreement to review a redacted version
of such agreement that is sufficient to confirm the foregoing obligations, and AFFIMED shall give due consideration to any comments of XOMA thereon. Prior to permitting or initiating any activity at a XOMA Authorized Site in the AFFIMED Field,
AFFIMED covenants that such XOMA Authorized Site shall (i) agree in advance in writing to be bound for the benefit of XOMA by all of the provisions of this Agreement; (ii) agree to implement such customary and usual safeguards as may be
necessary to insure that the XOMA Know-How is accessed and utilized on a “need to know” basis only; and (iii) agree that such XOMA Authorized Site shall undertake the activities solely on behalf of AFFIMED and as a result of such
activities shall not claim any license or right under the XOMA Patent Rights or XOMA Know-How for the benefit of itself or any other Third Party. AFFIMED shall remain fully and primarily liable for all actions of, or failures to act by, such XOMA
Authorized Site in connection therewith and agrees to hold XOMA harmless with respect thereto without qualification. For the avoidance of doubt, AFFIMED acknowledges that no such delegation of rights shall relieve AFFIMED of its responsibilities for
performance of any of its obligations hereunder. For the purposes of this Section 2.7, a “XOMA Authorized Site” shall mean one or more contract manufacturers designated in writing from time to time by XOMA. The terms and
conditions of any agreement between XOMA and the XOMA Authorized Site shall also apply to any activities undertaken on behalf of AFFIMED pursuant to this Section 2.7. No such entity or person shall be deemed to be a XOMA Authorized Site unless
and until, as to each Licensed Immunoglobulin or Immunoglobulin subject to Section 2.5(b), as applicable, to be produced pursuant to this Section 2.7, it enters into a legally binding 

  
 -12- 








 
agreement with AFFIMED that implements the provisions of this Section 2.7, naming XOMA as a third party beneficiary of those provisions of such agreement that pertain to confidentiality and
restrictions on transfer and use of Licensed Immunoglobulins, XOMA Patent Rights and XOMA Know-How provided for in this Agreement. 
 2.8
Reports, Records and Audits. 
 (a) ***** after the end of each calendar quarter, commencing with the first calendar quarter
commencing after the Effective Date, AFFIMED shall deliver to XOMA a written report which shall specify the name, address and contact person for each and every potential and actual AFFIMED Collaborator and any person or entity with whom AFFIMED has
engaged in Research, who has received any Transferred Materials or, in the case of the exercise of the Option in accordance with Section 2.5(a), who has received any clinical or commercial supplies manufactured by AFFIMED or with whom AFFIMED
is engaged in the commercialization of an Immunoglobulin subject to the Option of Section 2.5(a). The reports delivered by AFFIMED to XOMA pursuant to this Section 2.8(a) shall be Confidential Information of AFFIMED. 

(b) AFFIMED shall maintain records fully and properly reflecting those activities to be reported to XOMA pursuant to Section 2.8(a) (the
“Records”), in sufficient detail and in good scientific manner appropriate for patent, regulatory and manufacturing purposes for at least three (3) years. Upon the written request of XOMA and not more than once in each calendar
year, AFFIMED shall permit an independent consultant appointed by XOMA and subject to customary confidentiality restrictions, at XOMA’s expense, to have access during normal business hours to such of the records of AFFIMED as may be reasonably
necessary to verify compliance with the terms of this Agreement, as well as the accuracy of the reports hereunder. AFFIMED shall certify any statements by AFFIMED personnel as to their accuracy and correctness. 

2.9 Ownership; Enforcement. At all times XOMA will retain ownership of the XOMA Know-How and the XOMA Patent Rights and may use and
commercialize such XOMA Know-How and XOMA Patent Rights itself or with any Third Party. XOMA retains the right, at its sole discretion, to enforce, maintain and otherwise protect the XOMA Know-How and the XOMA Patent Rights. In addition to the
requirements of Section 2.8, AFFIMED shall give XOMA prompt notice of misappropriation of any of the XOMA Know-How, or any infringement of any of the XOMA Patent Rights, by a Third Party which comes to AFFIMED’ s attention during the term
of this Agreement. 
 2.10 No Admission of Infringement. The execution of this Agreement is not an admission that any action by
AFFIMED or AFFIMED Product either infringed or is infringing the XOMA Patent Rights and AFFIMED reserves all of its rights with respect to the practice of any technology and the production of any composition of matter or article of manufacture
unrelated to the XOMA Patent Rights or the XOMA Know-How.

 10.9 Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by
one party to the other are, for all purposes of Section 365(n) of Title XI of the United States Code (“Title XI’), licenses of rights to “intellectual property” as defined in Title XI. During the term of this
Agreement each party shall create and maintain current copies to the extent practicable of all such intellectual property. If a bankruptcy proceeding is commenced by or against one party under Title XI, the other party shall be entitled to a copy of
any and all such intellectual property and all embodiments of such intellectual property, and the same, if not in the possession of such other party, shall be promptly delivered to it (a) upon such party’s written request following the
commencement of such bankruptcy proceeding, unless the party subject to such bankruptcy proceeding, or its trustee or receiver, elects within thirty (30) days to continue to perform all of its obligations under this Agreement, or (b) if
not delivered as provided under clause (a) above, upon such other party’s request following the rejection of this Agreement by or on behalf of the party subject to such bankruptcy proceeding. If a party has taken possession of all
applicable embodiments of the intellectual property of the other party pursuant to this Section 10.9 and the trustee in bankruptcy of the other party does not reject this Agreement, the party in possession of such intellectual property shall
return such embodiments upon request. If a party seeks or involuntarily is placed under Title XI and the trustee rejects this Agreement as contemplated under 11 U.S.C. 365(n)(l), the other party hereby elects, pursuant to Section 365(n) of
Title XI, to retain all rights granted to it under this Agreement to the extent permitted by law.

shall use the name or trademarks of the other party, except to the extent that a party is permitted to use the Confidential Information of the other party pursuant to Article 7, without the prior written consent of such other party. 

10.11 Further Actions. Each party agrees to execute, acknowledge and deliver such further instruments, and do such other acts, as may
be necessary and appropriate in order to carry out the purposes and intent of this Agreement. 
 10.12 Entire Agreement; Amendment.
This Agreement constitutes the entire and exclusive Agreement between the parties with respect to the subject matter hereof and supersedes and cancels all previous discussions, agreements, commitments and writings in respect thereof. No amendment or
addition to this Agreement shall be effective unless reduced to writing and executed by the authorized representatives of the parties. 

10.13 Arbitration. 
 (a)
Any controversy or claim between the parties to this Agreement (other than any dispute which arises out of or relates to infringement, validity and/or enforceability of the XOMA Patent Rights (Text intentionally omitted.]) arising out of or relating
to this Agreement or the breach thereof shall be finally determined by arbitration in New York, in accordance with the International Arbitration Rules of the International Centre for Dispute Resolution (“ICDR”) or other rules agreed
to by the parties involved in the dispute, by a panel of three neutral arbitrators (at least two of whom who shall have significant experience in the biotechnology industry), who shall be selected by the parties involved in the dispute using the
procedures for arbitrator selection of the ICDR. 

  
 -21- 








 (b) The parties acknowledge that this Agreement evidences a transaction involving interstate
commerce and is subject to the New York Convention on enforcement of arbitral awards. Insofar as it applies, the United States Arbitration Act shall govern the interpretation of, enforcement of, and proceedings pursuant to the arbitration clause in
this Agreement. Except insofar as the United States Arbitration Act applies to such matters, the agreement to arbitrate set forth in this Section 10.13 shall be construed, and the legal relations among the parties shall be determined in
accordance with, the substantive laws of the State of New York. 
 (c) The panel shall render its decision and award, including a statement
of reasons upon which such award is based, within thirty (30) days after the arbitration hearing. The decision of the panel shall be determined by majority vote among the arbitrators, shall be in writing and shall be binding upon the parties
involved in the dispute, final and non-appealable. Judgment upon the award rendered by the panel may be entered in any court having jurisdiction thereof. 

(d) Except as provided under the United States Arbitration Act and with respect to the infringement, validity and/or enforceability of the
XOMA Patent Rights [Text intentionally omitted.], no action at law or in equity based upon any dispute that is subject to arbitration under this Section 10.13 shall be instituted. 

(e) The arbitral panel shall have the authority to award, in its discretion, part or all the expenses of any arbitration pursuant to this
Section 1 0.13, including fees and expenses of the prevailing party’s attorneys, fees and expenses of the arbitrators, and fees and expenses of any witness or the cost of any proof produced at the request of the arbitrators, to the
prevailing party. 
 10.14 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same instrument.

 SCHEDULE 2.4 

Form of Notice 
 XOMA owns a number
of patents covering various aspects of bacterial antibody expression and phage display. 
 XOMA has licensed these patents on a non-exclusive basis to
AFFIMED. 
 Under the license agreement with XOMA: 
  

	•	 	AFFIMED cannot provide evolution or phage display services or transfer related Immunoglobulin information to you without first showing you a redacted copy of its license from XOMA and this notice. 


 

	•	 	If you and AFFIMED enter into a written agreement by which you become a “AFFIMED Collaborator,” then you will be permitted to use AFFIMED evolution or phage display services and related Immunoglobulin and
information to research, develop and commercialize antibody Immunoglobulin. 

  

	•	 	Collaborators do not, however, have either the right to (a) produce commercial quantities of such antibodies using XOMA’s patented technology or (b) commercialize any results of research conducted by
AFFIMED. Rather, AFFIMED has the right to make Research quantities of antibodies using the XOMA patent rights. AFFIMED has the right to obtain licenses from XOMA on pre-negotiated terms, but subject to certain conditions. 


 

	•	 	Therefore, if you and AFFIMED enter into a written agreement, that agreement must contain certain provisions specified in the license agreement with XOMA, including: 


 

	 	•	 	Terms pursuant to which you, as the recipient of any transferred materials, would agree to abide by each of the limitations, restrictions and other obligations provided for by the license agreement with XOMA, including,
without limitation, the restrictions on use of such transferred materials for purposes other than Research. 

  

	 	•	 	A covenant not to use transferred materials for any purpose other than for Research purposes otherwise authorized by the license agreement with XOMA. 


 

	 	•	 	A provision that the “first sale” doctrine does not apply to any disposition of transferred materials. 









	 	•	 	An agreement by you to further dispose of transferred materials only to a third party who otherwise meets the definition of a “AFFIMED Collaborator” set forth in the license agreement with XOMA and who
executes a written agreement in which it undertakes all of the obligations applied to the transferring party.

 SCHEDULE 7.4 

For Immediate release: 
 XOMA and
Affimed Sign Antibody Cross-License and 
 Collaboration Agreement 

Berkeley, CA and Heidelberg, Germany – October 2, 2006 – XOMA Ltd. (Nasdaq: XOMA) and Affimed Therapeutics AG announced today that they
have signed a cross-license and collaboration agreement for antibody-related technologies. Financial terms were not disclosed. 
 The agreement
provides XOMA with a license under Affimed’s antibody library patents for antibody discovery purposes, as well as for the development and commercialization of antibodies. In addition, Affimed has agreed to build two customized patient-derived
human antibody phage display libraries according to XOMA specifications. 
 The agreement provides Affimed with a license to use XOMA’s Bacterial Cell
Expression (BCE) technology for research purposes, with an option to acquire a BCE license for production and commercialization of antibodies, in particular for Affimed’s proprietary TandAb and Flexibody technologies. XOMA also has agreed to
provide Affimed with cell line development and process development services specific to a TandAb therapeutic product candidate that Affimed is currently developing. 

“Affimed’s custom libraries represent a powerful addition to XOMA’s existing collection of the seven leading commercial human antibody phage
display libraries. The advantage of patient-derived libraries is their potential to contain unique antibody candidates for the therapeutic area of interest,” said Jack Castello, chairman of the board, president and chief executive officer of
XOMA. “This collaboration extends XOMA’s leadership in therapeutic antibodies, providing a single point of access to an even broader fully-integrated antibody discovery and development platform.” 

“We are delighted to enter into this broad cross-license and collaboration agreement with XOMA” said Rolf H. Günther MD PhD, chief executive
officer of Affimed. “The access to XOMA’s state-of-the-art BCE technology represents another very important milestone for Affimed and provides new opportunities for the development of Affimed’s promising recombinant antibody products.
In addition to having the rights to use this technology in our development work, we are particularly pleased to have the benefit of XOMA’s expertise in the development of cell lines and production systems for our TandAb therapeutic
candidate.” 
 About Affimed Therapeutics AG 

Affimed is a private biopharmaceutical company based in Heidelberg, Germany and specializing in the development of recombinant antibodies – the fastest
growing segment of the pharmaceutical industry. Affimed was founded in May of 2000 by Professor Melvyn Little as a spin-off of his group »Recombinant Antibodies« at the German Cancer Research Centre in Heidelberg. The strength of
Affimed’s discovery platform 







 
lies in three large distinct antibody libraries that are the source of antibody leads which can be produced in a variety of formats from scFv, diabodies, full length antibodies to proprietary
tetravalent formats such as Affimed’s TandAb or Flexibody. Affimed’s existing pipeline comprises several very novel antibody formats targeting some potentially very high value cancer targets. Two cancer products are in advanced
pre-clinical development. To learn more about Affimed, please visit www.affimed.com 
 About XOMA and its Bacterial Cell Expression Technology

 XOMA is a leader in the discovery, development and manufacture of therapeutic antibodies, with a therapeutic focus that includes cancer and immune
diseases. XOMA has royalty interests in RAPTIVA® (efalizumab), a monoclonal antibody product marketed worldwide (by Genentech, Inc. and Serono, SA) to treat moderate-to-severe plaque psoriasis, and LUCENTISTM (ranibizumab injection), a monoclonal antibody product marketed worldwide (by Genentech and Novartis AG) to treat neovascular (wet) age-related macular degeneration. 

The company has built a premier antibody discovery and development platform that includes access to seven of the leading commercially available antibody phage
display libraries and XOMA’s proprietary Human EngineeringTM and BCE technologies. BCE is an enabling technology used to discover and screen, as well as develop and manufacture, recombinant proteins and antibodies for commercial purposes.
BCE is also a key technology used in multiple systems for high throughput screening of antibody domains. XOMA scientists were the first to demonstrate the secretion of antibody domains directly from the bacterial cells as fully functional, properly
folded molecules. More than 45 companies have signed BCE licenses. 
 XOMA’s development collaborators include Lexicon Genetics Inc., Novartis and
Schering-Plough Corporation. With a fully integrated product development infrastructure, XOMA’s product development capabilities extend from preclinical sciences to product launch. The company’s pipeline also includes proprietary programs
in preclinical and clinical development. In addition, XOMA leverages its recombinant protein and antibody production infrastructure through process development and manufacturing contracts with public and private sector organizations. For more
information about XOMA’s product pipeline and antibody product development capabilities and technologies, please visit XOMA’s website at http://www.xoma.com/. 

Certain statements contained herein concerning product development, customized patient-derived libraries, or that otherwise relate to future periods are
forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements are based on assumptions that may not prove accurate. Actual results could
differ materially from those anticipated due to certain risks inherent in the biotechnology industry and for companies engaged in the development of new products in a regulated market. These risks, including those related to the results of discovery
research and preclinical testing; the timing or results of pending and future clinical trials (including the design and progress of clinical trials; safety and efficacy of the products being tested; action, inaction or delay by the FDA, European or
other regulators or their advisory bodies; and analysis or interpretation by, or submission to, these entities or others of scientific data); uncertainties 







 
regarding the status of biotechnology patents; uncertainties as to the cost of protecting intellectual property; changes in the status of the existing collaborative and licensing relationships;
the ability of collaborators, licensees and other third parties to meet their obligations; market demand for products; scale up and marketing capabilities; competition; international operations; share price volatility; XOMA’s financing needs
and opportunities and risks associated with XOMA’s status as a Bermuda company, are described in more detail in XOMA’s most recent annual report on Form 10-K and in other SEC filings. Consider such risks carefully in considering
XOMA’s prospects.
