    CHANGE
      OF CONTROL SEVERANCE AGREEMENT

     

    This
      Change of Control Severance Agreement (the “Agreement”) is made and
      entered into effective as of August 3, 2007 (the “Effective Date”), by and
      between Steven B. Engle (the “Employee”) and XOMA Ltd., a Bermuda company
      (the “Company”).

    A.           It
      is expected that the Company may from time to time consider the possibility
      of a
      Change of Control (as hereinafter defined).  The Board of Directors of
      the Company (the “Board”) recognizes that such consideration could be a
      distraction to the Employee and could cause the Employee to consider alternative
      employment opportunities.

     

    B.           The
      Board believes that it is in the best interest of the Company and its
      shareholders to provide the Employee with an incentive to continue the
      Employee’s employment and to maximize the value of the Company upon a Change of
      Control for the benefit of its shareholders.

     

    C.           In
      order to provide the Employee with enhanced financial security and sufficient
      encouragement to remain with the Company notwithstanding the possibility of
      a
      Change of Control, the Board believes that it is imperative to provide the
      Employee with certain severance benefits upon the Employee’s termination of
      employment following a Change of Control.

     

    D.           XOMA
      (US) LLC, a wholly-owned subsidiary of the Company, and the Employee have
      previously entered into an employment agreement effective as of August 3, 2007
      (the “Existing Agreement”), which provides the Employee with certain
      severance benefits upon the Employee’s termination of employment.

     

    E.           The
      parties intend that this Agreement shall operate in addition to, and not in
      replacement of, the Existing Agreement.

     

    AGREEMENT

     

    In
      consideration of the mutual covenants herein contained and the continued

      or
      inaction within thirty (30) days after the Employee’s receipt of notice from the
      Company of such action or inaction and the Board determines that such action
      or

      misfeasance of the Employee in respect of such duties, or (iii) the Employee

        2

      or, if earlier, on the date, prior to a Change of Control Protection Period,

    3.  At-Will

      Agreement or as may otherwise be established under the Company’s then existing
      employee benefit plans or policies at the time of termination.

     

    4.  Change
      of Control and Severance Benefits.

     

    
      
              

          
            	 

          
      

                       
    

        
        

      

      
        3

        
          

        

      

      
        
        

      

    

    (a)  Option
      Acceleration and Extended Exercise Period.  If the Employee’s
      employment with the Company terminates as a result of an Involuntary Termination
      at any time within a Change of Control Protection Period, then the
      exercisability of all options granted to the Employee by the Company (including
      any such options granted or assumed by the surviving or continuing entity of
      the
      Change of Control) and still outstanding (the “Options”) shall
      automatically be accelerated so that all the Options may be exercised
      immediately upon such Involuntary Termination for any or all of the shares
      subject thereto and the post-termination exercise period of each Option shall
      be
      extended to sixty (60) months (but in no event beyond the remainder of the
      maximum term of the Option).  The Options shall continue to be subject
      to all other terms and conditions of the Company’s share option plans and the
      applicable option agreements between the Employee and the Company.

     

    (b)  Outplacement
      Program.  If the Employee’s employment with the Company terminates
      as a result of an Involuntary Termination at any time within a Change of Control
      Protection Period, the Employee will immediately become entitled to participate
      in a twelve (12) month executive outplacement program provided by an executive
      outplacement service, at the Company’s expense not to exceed fifteen thousand
      dollars ($15,000).

     

    (c)  Termination
      Following a Change of Control.

     

    (i)  Cash
      Severance Payment Upon Involuntary Termination.  If the Employee’s
      employment with the Company terminates as a result of an Involuntary Termination
      at any time within a Change of Control Protection Period, then the Employee
      shall be entitled to receive a severance payment equal to the sum of (A) an
      amount equal to 2.0 times the Employee’s annual base salary as in effect
      immediately prior to the Involuntary Termination, plus (B) an amount equal
      to
      2.0 times Employee’s target bonus as in effect for the fiscal year in which the
      Involuntary Termination occurs.  Such severance payments shall be in
      lieu of any other severance payment to which the Employee shall be entitled
      as a
      result of such termination pursuant to this Agreement, any employment agreement
      with or offer letter from the Company or any of its affiliates or the Company’s
      or any of its affiliate’s then existing severance plans and
      policies.  The severance payment described in Section 4(c)(i)(A) shall
      be paid in monthly installments over twenty-four (24) months, beginning within
      thirty (30) days of the termination, and the severance payment described in
      Section 4(c)(i)(B) shall be paid in a lump sum within thirty (30) days of the
      termination, in each case subject to the requirements of Section 4(c)(iii)
      below.

     

    
      
              

          
            	 

          
      

                        
    

        
        

      

      
        4

        
          

        

      

      
        
        

      

    

    (ii)  Provision
      of Group Health and Certain Other Benefits.  In addition, during a
      period of twenty-four (24) months following the termination of Employee’s
      employment as a result of an Involuntary Termination at any time within a Change
      of Control Protection Period, (A) the Company shall make available and pay
      for
      the full cost of the coverage (plus an additional amount to pay for the taxes
      on
      such payments, if any, plus any taxes on such additional amount, such amount
      to
      be paid no later than ten (10) days prior to the date such taxes are due) of
      the
      Employee and Employee’s spouse and eligible dependents under any group health
      plans of the Company on the date of such termination of employment at the same
      level of health (i.e., medical, vision and dental) coverage and benefits as
      in
      effect for the Employee or such covered dependents on the date immediately
      preceding the date of the Employee’s termination; provided,
however, that (1) the Employee and Employee’s spouse and eligible
      dependents each constitutes a qualified beneficiary, as defined in Section
      4980B(g)(1) of the Internal Revenue Code of 1986, as amended; and (2) the
      Employee elects continuation coverage pursuant to the Consolidated Omnibus
      Budget Reconciliation Act of 1985, as amended (“COBRA”), within the time period
      prescribed pursuant to COBRA; and (B) if Employee is, at the time of such
      termination, an eligible participant in the Company’s mortgage differential
      program, the Company shall continue to make mortgage assistance payments to
      Employee pursuant to such program as in effect at the time of such
      termination.  Notwithstanding the foregoing, the payments by the
      Company for such group health coverage and/or mortgage assistance, as
      applicable, shall cease prior to the expiration of the twenty-four (24) month
      period in this Section 4(c)(ii) upon the employment of the Employment by another
      employer.  Furthermore, if, at the time of the termination of
      Employee’s employment as a result of an Involuntary Termination at any time
      within a Change of Control Protection Period, Employee is the obligor of a
      “forgivable” loan (i.e., a loan which by its terms is to be considered forgiven
      by the Company and paid by the obligor in circumstances other than actual
      repayment) from the Company, then, notwithstanding any provisions of such loan
      to the contrary, such loan shall remain outstanding, and the forgiveness thereof
      shall continue, for a period of twenty-four (24) months following such
      termination in accordance with the terms of such loan in effect at the time
      of
      such termination; provided, however, that at the end of such period of
      twenty-four (24) months, the outstanding balance of such loan shall be
      immediately due and payable, together with any accrued and unpaid interest
      thereon.

     

    
      
              

          
            	 

          
      

                        
    

        
        

      

      
        5

        
          

        

      

      
        
        

      

    

    (iii)  Section
      409A of the Code.  Notwithstanding the foregoing clauses (i) and
      (ii), to the extent any of the severance payments, mortgage assistance payments
      or loan forgiveness referred to therein, or any taxes payable on the health
      benefits referred to therein, would be deemed made in connection with a
“separation from service” within the meaning of the term in Section
      409A(a)(2)(A)(i) of the Code to a “specified employee” within the meaning of the
      term in Section 409A(a)(2)(B)(i) of the Code, and not exempt from the
      requirements of Section 409A of the Code, then such payments or forgiveness,
      as
      the case may be, shall be postponed until six (6) months following the
      Employee’s termination from employment as required by Section 409A of the Code,
provided, however, if prior to the expiration of such six-month
      period, the Employee dies, then such payments or forgiveness, as the case may
      be, shall commence prior to expiration of the six month period according to
      the
      original payment schedule for such payments to the extent permitted by Section
      409A of the Code.  Thus, for example, if the provision in the
      preceding sentence applies, the first six (6) monthly installments of the
      severance payments provided for in clause (i) above shall be paid immediately
      following the six (6) month period in a lump sum and the seventh (7th) through
      twenty-fourth (24th) installments
      shall be paid according to their original schedule provided that the Employee
      does not die during such six-month period.

     

    (iv)  Voluntary
      Resignation or Termination for Cause.  If the Employee’s
      employment with the Company terminates as a result of the Employee’s voluntary
      resignation which is not an Involuntary Termination or if the Employee is
      terminated for Cause at any time after a Change of Control, then the Employee
      shall not be entitled to receive severance or other benefits hereunder, but
      may
      be eligible for those benefits (if any) as may then be established under the
      Company’s then existing severance and benefits plans and policies at the time of
      such termination.

     

    (d)  Disability
      or Death.  If the Employee’s employment with the Company
      terminates due to the Employee’s death or disability following a Change of
      Control, then the Employee shall not be entitled to receive severance or other
      benefits hereunder, except for those (if any) as may be then established under
      the Company’s then existing severance and benefits plans and policies at the
      time of such disability or death.  In the event of the Employee’s
      death or disability after the termination of the Employee’s employment with the
      Company as a result of an Involuntary Termination within a Change of Control
      Protection Period, the Employee’s personal or legal representatives, executors,
      administrators, successors, heirs, distributees, devisees and legatees shall
      be
      entitled to receive severance or other benefits hereunder.

     

    
      
              

          
            	 

          
      

                        
    

        
        

      

      
        6

        
          

        

      

      
        
        

      

    

    (e)  Accrued
      Wages and Vacation; Expenses.  Without regard to the reason for,
      or the timing of, the Employee’s termination of employment (and without
      duplication of any similar benefits under any employment agreement with the
      Company or any of its affiliates):  (i) the Company shall pay the
      Employee any unpaid base salary due for periods prior to the date of
      termination; (ii) the Company shall pay the Employee all of the Employee’s
      accrued and unused vacation through the date of termination; and (iii) following
      submission of proper expense reports by the Employee, the Company shall
      reimburse the Employee for all expenses reasonably and necessarily incurred
      by
      the Employee in connection with the business of the Company prior to the date
      of
      termination.  These payments shall be made promptly upon termination,
      within the period of time mandated by law, and in no event later than ten (10)
      days after the date of termination.

     

    5.  Conditional
      Nature of Severance Payments.

     

    (a)  Non-Compete.  The
      Employee shall not, to the detriment of the Company or any of its affiliates,
      disclose or reveal to any unauthorized person any trade secret or other
      confidential information relating to the Company or its affiliates or to any
      businesses operated by them, and the Employee confirms that such information
      constitutes the exclusive property of the Company. The Employee shall not
      otherwise act or conduct her/himself to the material detriment of the Company
      or
      its affiliates, or in a manner which is inimical or contrary to the interests
      thereof, and, for a period of twenty-four (24) months following the termination
      of Employee’s employment as a result of an Involuntary Termination at any time
      within a Change of Control Protection Period, shall not, directly or indirectly,
      engage in or render any service (whether to a person, firm or business) in
      direct competition with the Company; provided, however, that the
      Employee’s ownership of less than five percent (5%) of the outstanding stock of
      a corporation shall not itself be deemed to constitute such competition. The
      Employee recognizes that the possible restrictions on her/his activities which
      may occur as a result of her/his performance of her/his obligations under this
      Section 5(a) are required for the reasonable protection of the Company and
      its
      investments.  For purposes hereof, “in direct competition” means
      engaged in the research, development and/or production of biological materials
      intended for use as therapeutic, prophylactic or diagnostic products in one
      or
      more of the same indications, and that utilize one or more of the same
      scientific bases (e.g., in the case of a therapeutic antibody, targets the
      same
      signal initiating pathway), as a product or product candidate the research,
      development and/or production of which is an active part of the Company’s
      business plan at the time of Employee’s termination.

     

    (b)  Non-Disparagement.  The
      Employee and the Company agree to refrain from any defamation, libel or slander
      of the other and its respective officers, directors, employees, representatives,
      investors, shareholders, administrators, affiliates, divisions, subsidiaries,
      predecessor and successor corporations and assigns or tortious interference
      with
      the contracts and relationships of the other and its respective officers,
      directors, employees, representatives, investors, shareholders, administrators,
      affiliates, divisions, subsidiaries, predecessor and successor corporations
      and
      assigns.

    (c)  Understanding
      of Covenants.  The Employee represents that the Employee (i) is
      familiar with the foregoing covenants not to compete and not to disparage,
      and
      (ii) is fully aware of the Employee’s obligations hereunder, including, without
      limitation, the reasonableness of the length of time, scope and geographic
      coverage of the covenant not to compete.

     

    6.  Golden
      Parachute Excise Tax.  In the event that the benefits provided for
      in this Agreement or otherwise payable to the Employee constitute “parachute
      payments” within the meaning of Section 280G of the Internal Revenue Code of
      1986, as amended (the “Code”) that are subject to the excise tax imposed
      by Section 4999 of the Code (the “Excise Tax”), then the Employee shall
      receive (i) a one-time payment from the Company sufficient to pay such excise
      tax (the “Excise Tax Gross-Up”), and (ii) an additional one-time payment
      from the Company sufficient to pay the additional excise tax and federal, state
      and local income and employment taxes arising from the Excise Tax Gross-Up
      made
      by the Company to the Employee pursuant to this Section 6 (the “Additional
      Gross-Up”).  Unless the Company and the Employee otherwise agree
      in writing, the determination of the Employee’s excise tax liability and the
      amount required to be paid under this Section 6 shall be made in writing in
      good
      faith by the accounting firm serving as the Company’s independent public
      accountants immediately prior to the Change of Control (the
“Accountants”).  The initial Excise Tax Gross-Up and Additional
      Gross-Up payments hereunder, if any, shall either be (x) paid to the Employee
      no
      later than ten (10) days prior to the due date for the payment of any excise
      tax, or (y) paid to the Internal Revenue Service on behalf of the Employee
      no
      later than the due date for the payment of any excise tax.  In the
      event that the Excise Tax incurred by the Employee is determined by the Internal
      Revenue Service to be greater or lesser than the amount so determined by the
      Accountants, the Company and the Employee agree to promptly (but in no event
      later than the end of the calendar year in which the applicable taxes are paid
      to (or received from) the Internal Revenue Service) make such additional
      payment, including interest and any tax penalties, to the other party as the
      Accountants reasonably determine is appropriate.  For purposes of
      making the calculations required by this Section 6, the Accountants may make
      reasonable assumptions and approximations concerning applicable taxes and may
      rely on interpretations concerning the application of the Code for which there
      is a “substantial authority” tax reporting position.  The Company and
      the Employee shall furnish to the Accountants such information and documents
      as
      the Accountants may reasonably request in order to make a determination under
      this Section 6.  The Company shall bear all costs the Accountants may
      reasonably incur in connection with any calculations contemplated by this
      Section 6.

     

    7.  Successors.

     

    
      
              

          
            	 

          
      

                        
    

        
        

      

      
        8

        
          

        

      

      
        
        

      

    

    (a)  Company’s
      Successors.  Any successor to the Company (whether direct or
      indirect and whether by purchase, lease, merger, amalgamation, consolidation,
      liquidation or otherwise) to all or substantially all of the Company’s business
      and/or assets shall assume the Company’s obligations under this Agreement and
      agree expressly to perform the Company’s obligations under this Agreement in the
      same manner and to the same extent as the Company would be required to perform
      such obligations in the absence of a succession.  For all purposes
      under this Agreement, the term “Company” shall include any successor to the
      Company’s business and/or assets which executes and delivers the assumption
      agreement described in this subsection (a) or which becomes bound by the terms
      of this Agreement by operation of law.

     

    (b)  Employee’s
      Successors.  Without the written consent of the Company, the
      Employee shall not assign or transfer this Agreement or any right or obligation
      under this Agreement to any other person or entity.  Notwithstanding
      the foregoing, the terms of this Agreement and all rights of the Employee
      hereunder shall inure to the benefit of, and be enforceable by, the Employee’s
      personal or legal representatives, executors, administrators, successors, heirs,
      distributees, devisees and legatees.

     

    8.  Notices.

     

    (a)  General.  Notices
      and all other communications contemplated by this Agreement shall be in writing
      and shall be deemed to have been duly given when personally delivered or when
      mailed by U.S. registered or certified mail, return receipt requested and
      postage prepaid.  In the case of the Employee, mailed notices shall be
      addressed to the Employee at the home address that the Employee most recently
      communicated to the Company in writing.  In the case of the Company,
      mailed notices shall be addressed to its corporate headquarters, and all notices
      shall be directed to the attention of its Secretary.

     

    (b)  Notice
      of Termination.  Any termination by the Company for Cause or by
      the Employee as a result of a voluntary resignation or an Involuntary
      Termination shall be communicated by a notice of termination to the other party
      hereto given in accordance with this Section 8.  Such notice shall
      indicate the specific termination provision in this Agreement relied upon,
      shall
      set forth in reasonable detail the facts and circumstances claimed to provide
      a
      basis for termination under the provision so indicated.  The failure
      by the Employee to include in the notice any fact or circumstance which
      contributes to a showing of Involuntary Termination shall not waive any right
      of
      the Employee hereunder or preclude the Employee from asserting such fact or
      circumstance in enforcing the Employee’s rights hereunder.

    9.  Execution
      of Release Agreement Upon Termination.  As a condition of entering
      into this Agreement and receiving the benefits under Section 4, the Employee
      agrees to execute and not revoke a release of claims agreement substantially
      in
      the form attached hereto as Exhibit A upon the termination of the
      Employee’s employment with the Company.  Such release shall not,
      however, apply to the rights and claims of the Employee under this Agreement,
      any indemnification agreement between the Employee and the Company (or its
      successor or acquirer), the bye-laws of the Company (or its successor or
      acquirer), the share award agreements between the Employee and the Company
      (or
      its successor or acquirer), or any employee benefit plan of which the Employee
      is a participant and under which all benefits due under such plan have not
      yet
      been paid or provided.

     

    10.  Arbitration.

     

    (a)  Any
      dispute or controversy arising out of, relating to, or in connection with this
      Agreement, or the interpretation, validity, construction, performance, breach,
      or termination thereof, shall be settled by binding arbitration to be held
      in
      San Francisco or Alameda County, California, in accordance with the National
      Rules for the Resolution of Employment Disputes then in effect of the American
      Arbitration Association (the “Rules”).  The cost of the
      arbitration shall be borne in full by the Company (or its successor or acquirer)
      but each of the Employee and the Company (or its successor or acquirer) shall
      bear his, her or its own legal fees and other cost in such arbitration subject
      to a possible award of attorneys fees and costs by the arbitrator as provided
      in
      the arbitration ruling.  The arbitrator may grant injunctions or other
      relief in such dispute or controversy.  The decision of the arbitrator
      shall be final, conclusive and binding on the parties to the
      arbitration.  Judgment may be entered on the arbitrator’s decision in
      any court having jurisdiction.

     

    (b)  The
      arbitrator(s) shall apply California law to the merits of any dispute or claim,
      without reference to conflicts of law rules.  The arbitration
      proceedings shall be governed by federal arbitration law and by the Rules,
      without reference to state arbitration law.  The Employee hereby
      consents to the personal jurisdiction of the state and federal courts located
      in
      California for any action or proceeding arising from or relating to this
      Agreement or relating to any arbitration in which the parties are
      participants.

     

    (c)  The
      Employee understands that nothing in this Section 10 modifies the Employee’s
      at-will employment status.  Either the Employee or the Company can
      terminate the employment relationship at any time, with or without
      cause.

    (d)  THE
      EMPLOYEE HAS READ AND UNDERSTANDS THIS SECTION, WHICH DISCUSSES
      ARBITRATION.  THE EMPLOYEE UNDERSTANDS THAT SUBMITTING ANY CLAIMS
      ARISING OUT OF, RELATING TO, OR IN CONNECTION WITH THIS AGREEMENT, OR THE
      INTERPRETATION, VALIDITY, CONSTRUCTION, PERFORMANCE, BREACH OR TERMINATION
      THEREOF TO BINDING ARBITRATION TO THE EXTENT PERMITTED BY LAW, AND THAT THIS
      ARBITRATION CLAUSE CONSTITUTES A WAIVER OF THE EMPLOYEE’S RIGHT TO A JURY TRIAL
      AND RELATES TO THE RESOLUTION OF ALL DISPUTES RELATING TO ALL ASPECTS OF THE
      EMPLOYER/EMPLOYEE RELATIONSHIP, INCLUDING BUT NOT LIMITED TO, THE FOLLOWING
      CLAIMS:

     

    (i)           ANY
      AND ALL CLAIMS FOR WRONGFUL DISCHARGE OF EMPLOYMENT; BREACH OF CONTRACT, BOTH
      EXPRESS AND IMPLIED; BREACH OF THE COVENANT OF GOOD FAITH AND FAIR DEALING,
      BOTH
      EXPRESS AND IMPLIED; NEGLIGENT OR INTENTIONAL INFLICTION OF EMOTIONAL DISTRESS;
      NEGLIGENT OR INTENTIONAL MISREPRESENTATION; NEGLIGENT OR INTENTIONAL
      INTERFERENCE WITH CONTRACT OR PROSPECTIVE ECONOMIC ADVANTAGE; AND
      DEFAMATION.

     

    (ii)           ANY
      AND ALL CLAIMS FOR VIOLATION OF ANY FEDERAL STATE OR MUNICIPAL STATUTE,
      INCLUDING, BUT NOT LIMITED TO, TITLE VII OF THE CIVIL RIGHTS ACT OF 1964, THE
      CIVIL RIGHTS ACT OF 1991, THE AGE DISCRIMINATION IN EMPLOYMENT ACT OF 1967,
      THE
      AMERICANS WITH DISABILITIES ACT OF 1990, THE FAIR LABOR STANDARDS ACT, THE
      CALIFORNIA FAIR EMPLOYMENT AND HOUSING ACT, AND LABOR CODE SECTION 201, et
      seq;

      AND ALL CLAIMS ARISING OUT OF ANY OTHER LAWS AND REGULATIONS RELATING TO
      EMPLOYMENT OR EMPLOYMENT DISCRIMINATION.

     

    11.  Miscellaneous
      Provisions.

     

    (a)  Mitigation.  The
      Employee shall not be required to mitigate the amount of any payment
      contemplated by this Agreement, nor shall any such payment be reduced by any
      earnings that the Employee may receive from any other
      source.  However, the Employee shall not be entitled to receive the
      health coverage and benefits contemplated by this Agreement in the event that
      the Employee receives similar health coverage and benefits as a result of new
      employment during the Compensation Continuation Period.

     

    
      
              

          
            	 

          
      

                        
    

        
        

      

      
        11

        
          

        

      

      
        
        

      

    

    (b)  Waiver.  No
      provision of this Agreement may be modified, waived or discharged unless the
      modification, waiver or discharge is agreed to in writing and signed by the
      Employee and by an authorized officer of the Company (other than the
      Employee).  No waiver by either party of any breach of, or of
      compliance with, any condition or provision of this Agreement by the other
      party
      shall be considered a waiver of any other condition or provision or of the
      same
      condition or provision at another time.

     

    (c)  Integration.  This
      Agreement represents the entire agreement and understanding between the parties
      with respect to the subject matter herein but shall not supersede any employment
      agreement between the Company or any of its affiliates and the Employee, any
      indemnification agreement between the Employee and the Company (or its successor
      or acquirer), the share award agreements between the Employee and the Company
      (or its successor or acquirer), or any employee benefit plan of which the
      Employee is a participant and under which all benefits due under such plan
      have
      not yet been paid or provided.

     

    (d)  Choice
      of Law.  The validity, interpretation, construction and
      performance of this Agreement shall be governed by the internal substantive
      laws, but not the conflicts of law rules, of the State of
      California.

     

    (e)  Severability.  The
      invalidity or unenforceability of any provision or provisions of this Agreement
      shall not affect the validity or enforceability of any other provision hereof,
      which shall remain in full force and effect.

     

    (f)  Tax
      Withholdings.  All payments made pursuant to this Agreement shall
      be subject to withholding of applicable income and employment
      taxes.

     

    (g)  Compliance
      with Section 409A of the Code.  It is intended that this Agreement
      will comply with Section 409A of the Code (and any regulations and guidelines
      issued thereunder) to the extent the Agreement is subject thereto, and the
      Agreement shall be interpreted on the basis consistent with such
      intent.

     

    (h)  Counterparts.  This
      Agreement may be executed in counterparts, each of which shall be deemed an
      original, but all of which together will constitute one and the same
      instrument.

     

    IN
      WITNESS WHEREOF, each of the parties has executed this Agreement, in the case
      of
      the Company by its duly authorized officer, as of the day and year first above
      written.

      THEREFORE, in consideration of the mutual promises made herein and other good
      and valuable consideration, the receipt and sufficiency of which are hereby

      released.  Notwithstanding the foregoing, this release does not extend
      to any obligations now or subsequently incurred under this Agreement, the
      Severance Agreement, the Indemnification Agreement between the Employee and
      the
      Company (or its successor or acquirer), the outstanding share award agreements
      between the Employee and the Company (or its successor or acquirer), or any
      employee benefit plan of which the Employee is a participant and under which
      all
      benefits due under such plan have not yet been paid or provided.

    4.  Acknowledgment
      of Waiver of Claims under ADEA.  The Employee acknowledges that
      the Employee is waiving and releasing any rights the Employee may have under
      the
      Age Discrimination in Employment Act of 1967 (“ADEA”) and that this waiver and
      release is knowing and voluntary.  The Employee and the Company agree
      that this waiver and release does not apply to any rights or claims that may
      arise under the ADEA after the Effective Date of this Agreement.  The
      Employee acknowledges that the consideration given for this waiver and release
      agreement is in addition to anything of value to which the Employee was already

    5.  Civil
      Code Section 1542.  The Employee represents that the Employee is
      not aware of any claims against the Company other than the claims that are
      released by this Agreement.  The Employee acknowledges that the
      Employee has been advised by legal counsel and is familiar with the provisions
      of California Civil Code Section 1542, which provides as follows:

     

    A
      GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW
      OR
      SUSPECT TO EXIST IN HER OR HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE,

      WITH
      THE DEBTOR.

     

    The
      Employee, being aware of said code section, agrees to expressly waive any rights
      the Employee may have thereunder, as well as under any other statute or common

      Employee does not intend to bring any claims on the Employee’s own behalf or on
      behalf of any other person or entity against the Company or any other person
      or
      entity referred to herein except, if necessary, with respect to the agreements
      listed in the last sentence of Section 4 of this Agreement.

     

    
      
              

          
            	 

          
      

                        
    

        
        

      

      
        A-3

        
          

        

      

      
        
        

      

    

    7.  Confidentiality.  The
      Employee agrees to use the Employee’s best efforts to maintain in confidence the
      existence of this Agreement, the contents and terms of this Agreement, and
      the
      consideration for this Agreement (hereinafter collectively referred to as
“Release Information”).  The Employee agrees to take every reasonable
      precaution to prevent disclosure of any Release Information to third parties
      and

      disclose Release Information only to those attorneys, accountants, governmental
      entities and family members who have a reasonable need to know of such Release
      Information.

     

    8.  No
      Adverse Cooperation.  The Employee agrees the Employee will not
      act in any manner that might damage the business of the Company.  The
      Employee agrees that the Employee will not counsel or assist any attorneys
      or
      their clients in the presentation or prosecution of any disputes, differences,
      grievances, claims, charges or complaints by any third party against the Company
      and/or any officer, director, employee, agent, representative, shareholder
      or
      attorney of the Company, unless compelled under a subpoena or other court order
      to do so.

     

    9.  Costs.  The
      Parties shall each bear their own costs, expert fees, attorneys’ fees and other
      fees incurred in connection with this Agreement.

     

    10.  Authority.  The

    11.  No
      Representations.  The Employee represents that the Employee has
      had the opportunity to consult with an attorney, and has carefully read and
      understands the scope and effect of the provisions of this
      Agreement.  Neither party has relied upon any representations or
      statements made by the other party hereto which are not specifically set forth
      in this Agreement.

     

    12.  Severability.  In
      the event that any provision hereof becomes or is declared by a court of
      competent jurisdiction to be illegal, unenforceable or void, this Agreement
      shall continue in full force and effect without said provision.

     

    13.  Entire
      Agreement.  This Agreement and the Severance Agreement and the
      agreements and plans referenced therein represent the entire agreement and
      understanding between the Company and the Employee concerning the Employee’s
      separation from the Company, and supersede and replace any and all prior
      agreements and understandings concerning the Employee’s relationship with the
      Company and the Employee’s compensation by the Company.  This
      Agreement may only be amended in writing signed by the Employee and an executive
      officer of the Company.

    16.  Counterparts.  This
      Agreement may be executed in counterparts, and each counterpart shall have
      the

                Share Option

            

    

    

     

    XOMA
      Ltd.
      (the "Company") has granted you an option to purchase the number of Common
      Shares shown in item (C) above (the "Optioned Shares") at the Exercise Price
      per
      share shown in item (G) above. This option is subject to the terms of the
      Company's 1981 Share Option Plan, as amended through December 8, 2004 (the
      "Plan") and to the terms and conditions set forth in this Share Option Agreement
      under the XOMA Ltd. 1981 Share Option Plan (the "Agreement").

     

    The
      details of your option are as follows:

     

     

    1.           Term;
      Transfer.  The term of this option commences on the Grant
      Date shown in item (B) above and, except as provided in Section 3 and Subsection
      5(a) hereof, expires at the close of business on the Expiration Date shown
      in
      item (F) above, which is 10 years from the Grant Date.

     

    This
      option may be transferred or assigned to your spouse or descendent (any such
      spouse or descendent, your "Immediate Family Member") or a corporation,
      partnership, limited liability company or trust so long as all of the
      shareholders, partners, members or beneficiaries thereof, as the case may be,
      are either you or your Immediate Family Member, provided that (i) there may
      be
      no consideration for any such transfer and (ii) subsequent transfers of the
      transferred option will be prohibited other than by will or the laws of descent
      and distribution. Following transfer, the option will continue to be subject
      to
      the same terms and conditions as were applicable immediately prior to transfer,
      provided that for purposes of this Agreement any references to "you" will refer
      to the transferee. The events of termination of employment will continue to
      be
      applied with respect to you, following which the option will be exercisable
      by
      the transferee only to the extent, and for the periods specified, in this
      Agreement.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    2.           Exercise
      Schedule.  The option granted herein is exercisable
      immediately on this date of grant.

     

    This
      option may be exercised in whole or in part in increments of 25 or more shares
      and, to the extent not exercised, will accumulate and be exercisable at any
      time
      on or before the Expiration Date or sooner termination of the option
      term.

     

     

    3.           Effect
      of Termination of Employment.

     

    (a)           If
      you cease to be an employee of the Company at any time during the option term
      for any reason other than as provided in Subsections (b), (c), (d) or (e) below,
      then the period for exercising this option will be limited to the three-month
      period commencing with the date of such cessation of employee status; provided
      that, notwithstanding the foregoing, if you cease to be an employee of the
      Company and immediately thereafter become a consultant to the Company at any
      time during the option term, then the period for exercising this option will
      not
      be limited as aforesaid but will be limited to the three-month period commencing
      with the date of cessation of consultant status, if during the option term;
      and
      provided further, that in no event will this option be exercisable at any time
      after the Expiration Date.  Upon the expiration of any such limited
      period of exercisability or (if earlier) upon the Expiration Date, this option
      will terminate and cease to be outstanding.

     

    (b)           If
      you die and cease by reason thereof to be either an employee of or a consultant
      to the Company at any time during the option term, then this option will remain
      exercisable for a twelve-month period following the date of death; provided,
      however, that in no event shall this option be exercisable at any time after
      the
      Expiration Date.  Upon the expiration of such twelve-month period or
      (if earlier) upon the Expiration Date, this option will terminate and cease
      to
      be outstanding.  Upon your death, the option will be exercisable by
      the personal representative of your estate or by the person or persons to whom
      the option is transferred pursuant to Section 1 above, provided any such
      exercise occurs prior to the earlier of (i) the expiration of the
      twelve-month period following the date of your death or (ii) the specified
      Expiration Date of the option term.

     

    (c)           If
      you become permanently disabled and cease by reason thereof to be either an
      employee of or a consultant to the Company at any time during the option term,
      then you will have a period of twelve months (commencing with the date of such
      cessation of employee or consultant status, as the case may be) during which
      to
      exercise this option; provided, however, that in no event shall this option
      be
      exercisable at any time after the Expiration Date.  Upon the
      expiration of such limited period of exercisability or (if earlier) upon the
      Expiration Date, this option will terminate and cease to be outstanding. You
      will be deemed to be permanently disabled if you are, by reason of any medically
      determinable physical or mental impairment expected to result in death or to
      be
      of continuous duration of not less than twelve consecutive months or more,
      unable to perform your usual duties for the Company or its
      subsidiaries.

     

    (d)           If
      you retire at or after age fifty-five (55) and the sum of your age on the date
      of retirement plus years of full-time employment or consultancy with the Company
      exceeds seventy (70) ("Retirement") and if by reason thereof you cease to be
      either an employee of or consultant to the Company, at any time during the
      option term, then this option will remain exercisable for the full option term
      until the Expiration Date as if you had continued in employment or
      consultancy.  On the Expiration Date, the option will terminate and
      cease to be outstanding.

     

    
      
        
        

      

      
        2

        
          

        

      

      
        
        

      

    

    (e)           Should
      (i) your status as either an employee or a consultant be terminated for cause
      (including, but not limited to, any act of dishonesty, willful misconduct,
      fraud
      or embezzlement or any unauthorized disclosure or use of confidential
      information or trade secrets), or (ii) you make or attempt to make any
      unauthorized use or disclosure of confidential information or trade secrets
      of
      the Company or its subsidiaries, then in any such event this option will
      terminate and cease to be exercisable immediately upon the date of such
      termination of employee or consultant status, as the case may be, or such
      unauthorized use or disclosure of confidential or secret information or attempt
      thereat.

     

    (f)           For
      purposes of this Agreement, you will be deemed to be an employee of the Company
      for so long as you remain in the employ of the Company or one or more of its
      subsidiaries, and you will be deemed to be a consultant to the Company for
      so
      long as you are actively rendering consulting services on a periodic basis
      to
      the Company or one or more of its subsidiaries. A legal entity will be deemed
      to
      be a subsidiary of the Company if it is a member of an unbroken chain of legal
      entities beginning with the Company, provided that each such legal entity in
      the
      chain (other than the last legal entity) owns, at the time of determination,
      shares possessing 50% or more of the total combined voting power of all classes
      of shares  in one of the other legal entities in such
      chain.

     

     

    4.           Adjustment
      in Option Shares.

     

    (a)           If
      any change is made to the Common Shares issuable under the Plan, whether by
      reason of any share dividend, share split, combination of shares,
      recapitalization or other change affecting the outstanding Common Shares as
      a
      class without receipt of consideration, then appropriate adjustments will be
      made to (i) the total number of Optioned Shares subject to this option and
      (ii)
      the Exercise Price payable per share, in order to reflect such change and
      thereby preclude the dilution or enlargement of benefits under this Agreement.
      The adjustments determined by the plan administrator (the "Plan Administrator")
      will be final, binding and conclusive.

     

    (b)           If
      the Company is the surviving or continuing entity in any merger, amalgamation
      or
      other business combination, then this option, if outstanding under the Plan
      immediately after such merger, amalgamation or other business combination,
      will
      be appropriately adjusted to apply and pertain to the number and class of
      securities which the holder of the same number of Common Shares as are subject
      to this option immediately prior to such merger, amalgamation or other business
      combination would have been entitled to receive in the consummation of such
      merger, amalgamation or other business combination, and an appropriate
      adjustment will be made to the Exercise Price payable per share, provided the
      aggregate Exercise Price payable hereunder will remain the same.

     

     

    5.           [Intentionally
      omitted.]

     

     

    6.           Privilege
      of Share Ownership.  The holder of this option will not
      have any rights of a shareholder with respect to the Optioned Shares until
      such
      individual has exercised the option, paid the Exercise Price and been issued
      a
      certificate for the purchased shares.

     

     

    7.           Manner
      of Exercising Option.

     

    (a)           In
      order to exercise this option with respect to all or any part of the Optioned
      Shares, you (or in the case of exercise after your death, your executor,
      administrator, heir, legatee or transferee as the case may be) must take the
      following actions:

     

    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

    

    (i)  Provide
      the Secretary of the Company with written notice of such exercise, specifying
      the number of Optioned Shares with respect to which the option is being
      exercised.

     

    (ii)  Pay
      the Exercise Price for the purchased Optioned Shares in one or more of the
      following alternative forms:  (A) full payment in cash or by check
      payable to the Company's order; (B) full payment in Common Shares of the Company
      valued at fair market value on the exercise date (as such terms are defined
      below); (C) full payment in combination of Common Shares of the Company valued
      at fair market value on the exercise date and cash or check payable to the
      Company's order; (D) payment effected through a broker-dealer sale and
      remittance procedure pursuant to which you (I) will provide irrevocable written
      instructions to the designated broker-dealer to effect the immediate sale of
      the
      purchased shares and remit to the Company, out of the sale proceeds, an amount
      equal to the aggregate Exercise Price payable for the purchased shares plus
      all
      applicable Federal and State income and employment taxes required to be withheld
      by the Company by reason of such purchase and (II) will provide written
      directives to the Company to deliver the certificates for the purchased shares
      directly to such broker-dealer; or, to the extent the Plan Administrator
      specifically authorizes such method of payment at the time of exercise, (E)
      payment by a full-recourse promissory note. Any such promissory note authorized
      by the Plan Administrator will be substantially in the form approved by the
      Plan
      Administrator, will bear interest at the minimum per annum rate necessary to
      avoid the imputation of interest income to the Company and compensation income
      to you under the Federal tax laws and will become due in full (in one or more
      consecutive annual installments measured from the execution date of the note)
      not later than the Expiration Date of this option. Payment of the note will
      be
      secured by the pledge of the purchased shares, and the pledged shares will
      be
      released only as the note is paid.

     

    (iii)  Furnish
      to the Company appropriate documentation that the person or persons exercising
      the option, if other than you, have the right to exercise this
      option.

     

    (b)           For
      purposes of Subsection 7(a) hereof, the fair market value per Common Share
      on
      any relevant date will be determined in accordance with Subsections (i) through
      (iii) below, and the exercise date will be the date on which you exercise this
      option in compliance with the provisions of Subsection 7(a).

     

    (i)  If
      the Common Shares are not listed or admitted to trading on any stock exchange
      on
      the date in question, but is traded in the over-the-counter market, the fair
      market value will be the closing selling price per share of such shares on
      such
      date, as such price is reported by the National Association of Securities
      Dealers through its Nasdaq National Market. If there is no reported closing
      selling price of the shares on the date in question then the closing selling
      price on the last preceding date for which such quotation exists will be
      determinative of fair market value.

     

    
      
        
        

      

      
        4

        
          

        

      

      
        
        

      

    

    (ii)  If
      the Common Shares are listed or admitted to trading on any stock exchange on
      the
      date in question, the fair market value will be the closing selling price per
      share of such shares on such date on the stock exchange determined by the Plan
      Administrator to be the primary market for such shares, as such price is
      officially quoted on such exchange. If there is no reported closing selling
      price of such shares on such exchange on the date in question, the fair market
      value will be the closing selling price on the exchange on the last preceding
      date for which such quotation exists.

     

    (iii)  If
      the Common Shares are neither listed nor admitted to trading on any stock
      exchange nor traded in the over-the-counter market on the date in question
      or if
      the Plan Administrator determines that the quotations under Subsections (i)
      or
      (ii) above do not accurately reflect the fair market value of such shares,
      the
      fair market value will be determined by the Plan Administrator after taking
      into
      account such factors as the Plan Administrator may deem appropriate, including
      one or more independent professional appraisals.

     

    (c)           In
      no event may this option be exercised for any fractional share.

     

     

    8.           Compliance
      with Laws and Regulations.

     

    (d)           The
      exercise of this option and the issuance of Optioned Shares upon such exercise
      will be subject to compliance by the Company and by you with all applicable
      requirements of law relating thereto and with all applicable regulations of
      any
      stock exchange on which the Company's Common Shares may be listed at the time
      of
      such exercise and issuance.

     

    (e)           In
      connection with the exercise of this option, you will execute and deliver to
      the
      Company such representations in writing as may be requested by the Company
      in
      order for it to comply with the applicable requirements of Federal and State
      securities laws.

     

     

    9.           Restrictive
      Legends.  If and to the extent any Optioned Shares
      acquired under this option are not registered under the Securities Act of 1933,
      the certificates for such Optioned Shares will be endorsed with restrictive
      legends, including (without limitation) the following:

     

    "The
      Shares represented by this certificate have not been registered under the
      Securities Act of 1933. The shares have been acquired for investment and may
      not
      be sold or offered for sale in the absence of (a) an effective registration
      statement for the shares under such Act, (b) a 'no action' letter of the
      Securities and Exchange Commission with respect to such sale or offer, or (c)
      an
      opinion of counsel to the Company that registration under such Act is not
      required with respect to such sale or offer."

     

     

    10.           Successors
      and Assigns.  Except to the extent otherwise provided in
      Section 1 and Subsection 5(a), the provisions of this Agreement will inure
      to
      the benefit of, and be binding upon your successors, administrators, heirs,
      legal representatives and assigns and the successors and assigns of the
      Company.

     

    
      
        
        

      

      
        5

        
          

        

      

      
        
        

      

    

     

    11.           Liability
      of the Company.

     

    (f)           If
      the Optioned Shares covered by this Agreement exceed, as of the Grant Date,
      the
      number of Common Shares which may without shareholder approval be issued under
      the Plan, then this option will be void with respect to such excess shares
      unless shareholder approval of an amendment sufficiently increasing the number
      of Common Shares issuable under the Plan is obtained in accordance with the
      provisions of the Plan.

     

    (g)           The
      inability of the Company to obtain approval from any regulatory body having
      authority deemed by the Company to be necessary to the lawful issuance and
      sale
      of any Common Shares pursuant to this option will relieve the Company of any
      liability in respect of the non-issuance or sale of such shares as to which
      such
      approval will not have been obtained.

     

     

    12.           No
      Employment or Consulting Contract.  Nothing in this
      Agreement or in the Plan will confer upon you any right to continue in the
      employ or service of the Company for any period of time or interfere with or
      otherwise restrict in any way the rights of the Company (or any subsidiary
      of
      the Company employing or retaining you) or you, which rights are hereby
      expressly reserved by each, to terminate your employee or consultant status
      as
      the case may be, at any time for any reason whatsoever, with or without
      cause.

     

     

    13.           Notices.  Any
      notice required to be given or delivered to the Company under the terms of
      this
      Agreement will be in writing and addressed to the Company in care of its
      Secretary at its principal offices. Any notice required to be given or delivered
      to you will be in writing and addressed to you at the address indicated below
      your signature line herein. All notices will be deemed to be given or delivered
      upon personal delivery or upon deposit in the U.S. mail, postage prepaid and
      properly addressed to the party to be notified.

     

     

    14.           Construction.  This
      Agreement and the option evidenced hereby are made and granted pursuant to
      the
      Plan and are in all respects limited by and subject to the express terms and
      provisions of the Plan. Any dispute regarding the interpretation of this
      Agreement will be submitted to the Plan Administrator for resolution. The
      decision of the Plan Administrator will be final, binding and conclusive.
      Questions regarding this option or the Plan should be referred to the Legal
      Department of the Company.

     

     

    15.           Governing
      Law.  The interpretation, performance, and enforcement of
      this Agreement will be governed by the laws of the State of
      California.

     

    16.           [Intentionally
      omitted.]

     

     

    17.           Tax
      Arrangements.  You hereby agree to make appropriate
      arrangements with the Company or subsidiary thereof by which you are employed
      or
      retained for the satisfaction of all Federal, State or local income tax
      withholding requirements and Federal social security employee tax requirements
      applicable to the exercise of this option.
