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:

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.

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;

(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;

-8-

(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 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); (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

(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.

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.

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.

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 LUCENTIS^™ (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 Engineering™ 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.
