Exhibit 10.10    
    


 
 

NEORX CORPORATION
  CHANGE OF CONTROL AGREEMENT    
    


        This Change of Control Agreement (VP) (this "Agreement"), dated as of February 28, 2003, is entered into by
and between NEORX CORPORATION, a Washington corporation (as supplemented by Section 13, the "Company"), and Anna Wight (the
"Executive"). 



        The
Board of Directors of the Company (the "Board") has determined that it is in the best interests of the Company and its shareholders to
ensure that the Company will have the continued dedication of the Executive, notwithstanding the possibility, threat or occurrence of a Change of Control (as defined in Section 1 hereof) of the
Company. The Board believes it is imperative to diminish the inevitable distraction of the Executive arising from the personal uncertainties and risks created by a pending or threatened Change of
Control, to encourage the Executive's full attention and dedication to the Company currently and in the event of any threatened or pending Change of Control, and to provide the Executive with
reasonable compensation and benefit arrangements upon a Change of Control. 


        In
order to accomplish these objectives, the Board has caused the Company to enter into this Agreement. 


1.     Definitions  


        1.1   "Change of Control" shall have the definition set forth in Appendix A hereto, which is hereby incorporated by
reference. 


        1.2   "Change of Control Date" shall mean the first date on which a Change of Control occurs. 


        1.3   "Employment Period" shall mean the two (2) year period commencing on the Change of Control Date and ending on the
second anniversary of such date. 


        1.4   "Severance Agreement" shall mean the Key Executive Severance Agreement, dated as of the date hereof, between the parties,
as it may be amended from time to time, that provides for certain benefits related to termination of the Executive's employment that are unrelated to a Change of Control. 


2.     Term  


        The initial term of this Agreement ("Initial Term") shall be for a period of one (1) year from the date of
this Agreement as first appearing above; provided, however, that this Agreement shall automatically renew for successive additional one (1) year periods ("Renewal
Terms") unless notice of nonrenewal is given by either party to the other at least ninety (90) days prior to the end of the Initial Term or any Renewal Term, and
provided further that if a Change in Control occurs during the Term, the Term shall automatically extend for the duration of the Employment Period. The
"Term" of this Agreement shall be the Initial Term plus all Renewal Terms and, if applicable, the duration of the Employment Period. At the end of the
Term, this Agreement shall terminate without further action by either the Company or the Executive. 


3.     Employment  


        3.1   Employment Period  



        During the Employment Period, the Company hereby agrees to continue the Executive in its employ or in the employ of its affiliated companies, and the Executive
hereby agrees to remain in the employ of the Company or its affiliated companies, in accordance with the terms and provisions of this Agreement; provided, however, that either the Company or the
Executive may terminate the employment relationship subject to the terms of this Agreement. 





 



        3.2   Position and Duties  



        During the Employment Period, the Executive's position, authority, duties and responsibilities shall be at least commensurate in all material respects with the
most significant of those held, exercised and assigned at any time during the ninety (90) day period immediately preceding the Change of Control Date. 


        3.3   Location  


        During the Employment Period, the Executive's services shall be performed at the Company's headquarters on the Change of Control Date or any office that is
subsequently designated as the headquarters of the Company and is less than thirty (30) miles from such location. 


        3.4   Employment at Will  


        The Executive and the Company acknowledge that, except as may otherwise be provided under any other written agreement between the Executive and the Company, the
employment of the Executive by the Company or its affiliated companies is "at will" and may be terminated by either the Executive or the Company or its affiliated companies at any time with or without
cause. Moreover, if prior to the Change of Control Date, the Executive's employment with the Company or its affiliated companies terminates for any reason, then the Executive shall have no further
rights under this Agreement; provided, however, that the Company may not avoid liability for any termination payments that would have been required during the Employment Period pursuant to
Section 8 hereof by terminating the Executive prior to the Employment Period where such termination is carried out in anticipation of a Change of Control and the principal motivating purpose is
to avoid liability for such termination payments. 


4.     Attention And Effort  


        During the Employment Period, and excluding any periods of vacation and sick leave to which the Executive is entitled, the Executive will devote all of her
productive time, ability, attention and effort to the business and affairs of the Company and the discharge of the responsibilities assigned to her hereunder, and will use her reasonable best efforts
to perform faithfully and efficiently such responsibilities. It shall not be a violation of this Agreement for the Executive to (a) serve on corporate, civic or charitable boards or committees,
(b) deliver lectures, fulfill speaking engagements or teach at
educational institutions, (c) manage personal investments, or (d) engage in activities permitted by the policies of the Company or as specifically permitted by the Company, so long as
such activities do not significantly interfere with the performance of the Executive's responsibilities in accordance with this Agreement. It is expressly understood and agreed that to the extent any
such activities have been conducted by the Executive prior to the Employment Period, the continued conduct of such activities (or the conduct of activities similar in nature and scope thereto) during
the Employment Period shall not thereafter be deemed to interfere with the performance of the Executive's responsibilities to the Company. 


5.     Compensation  


        As long as the Executive remains employed by the Company during the Employment Period, the Company agrees to pay or cause to be paid to the Executive, and the
Executive agrees to accept in exchange for the services rendered hereunder by him, the following compensation: 


        5.1   Salary  


        The Executive shall receive an annual base salary (the "Annual Base Salary"), at least equal to the annual salary
established by the Board or the Compensation Committee of the Board (the 


2





 



"Compensation Committee") or the Chief Executive Officer for the fiscal year in which the Change of Control Date occurs. The Annual Base Salary shall be
paid in substantially equal installments and at the same intervals as the salaries of other executives of the Company are paid. The Board or the Compensation Committee or the Chief Executive Officer
shall review the Annual Base Salary at least annually and shall determine in good faith and consistent with any generally applicable Company policy any increases for future years. 



        5.2   Bonus  


        In addition to the Annual Base Salary, the Executive shall be awarded, for each fiscal year ending during the Employment Period, an annual bonus (the
"Annual Bonus") in cash at least equal to the average annualized (for any fiscal year consisting of less than twelve (12) full months) bonus paid
or payable (including by reason of any deferral and including the value of any stock awards and the compensation expense disclosed in the Company's financial statements for the grant of any stock
options) to the Executive by the Company and its affiliated companies in respect of the three fiscal years immediately preceding the fiscal year in which the Change of Control Date occurs. Each Annual
Bonus shall be paid no later than ninety (90) days after the end of the fiscal year for which the Annual Bonus is awarded, unless the Executive shall elect to defer the receipt of the Annual
Bonus. 


6.     Benefits  


        6.1   Incentive, Retirement and Welfare Benefit Plans; Vacation  


        During the Employment Period, the Executive shall be entitled to participate, subject to and in accordance with applicable eligibility requirements, in such
fringe benefit programs as shall be generally made available to other executives of the Company and its affiliated companies from time to time during the Employment Period by action of the Board (or
any person or committee appointed by the Board to determine fringe benefit programs and other emoluments), including, without limitation, paid vacations; any stock purchase, savings or retirement
plan, practice, policy or program; and all welfare benefit plans, practices, policies or programs (including, without limitation, medical, prescription, dental, disability, salary continuance,
employee life, group life, accidental death and travel accident insurance plans or programs). 


        6.2   Expenses  



        During the Employment Period, the Executive shall be entitled to receive prompt reimbursement for all reasonable employment expenses incurred by her in accordance
with the policies, practices and procedures of the Company and its affiliated companies in effect for the executives of the Company and its affiliated companies during the Employment Period. 


7.     Termination  


        During the Employment Period, employment of the Executive may be terminated as follows, but, in any case, the nondisclosure provisions set forth in
Section 10 hereof shall survive the termination of this Agreement and the termination of the Executive's employment with the Company: 


        7.1   By the Company or the Executive  


        At any time during the Employment Period, the Company may terminate the employment of the Executive with or without Cause (as defined below), and the Executive
may terminate her employment for Good Reason (as defined below) or for any reason, upon giving the Notice of Termination (as defined below). 


3





 



        7.2   Automatic Termination  


        This Agreement and the Executive's employment during the Employment Period shall terminate automatically upon the death or Total Disability of the Executive. The
term "Total Disability" as used herein shall mean the Executive's inability (with such accommodation as may be required by law and which places no undue
burden on the Company), as determined by a physician selected by the Company and acceptable to the Executive, to perform the duties set forth in Section 3.2 hereof for a period or periods
aggregating twelve (12) weeks in any three hundred sixty-five (365) day period as a result of physical or mental illness, loss of legal capacity or any other cause beyond the
Executive's control, unless the Executive is granted a leave of absence by the Board. The Executive and the Company hereby acknowledge that the duties specified in Section 3.2 hereof are
essential to the Executive's position and that Executive's ability to perform those duties is the essence of this Agreement. 


        7.3   Notice of Termination  


        Any termination by the Company or by the Executive during the Employment Period shall be communicated by the Notice of Termination to the other party given in
accordance with Section 12 hereof. The term "Notice of Termination" shall mean a written notice that (a) indicates the specific
termination provision in this Agreement relied upon and (b) to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of
the Executive's employment under the provision so indicated. The failure by the Executive or the Company to set forth in the Notice of Termination any fact or circumstance that contributes to a
showing of Good Reason or Cause shall not waive any right of the Executive or the Company hereunder or preclude the Executive or the Company from asserting such fact or circumstance in enforcing the
Executive's or the Company's rights hereunder. 


        7.4   Date of Termination  


        During the Employment Period, "Date of Termination" means (a) if the Executive's employment is terminated
by reason of death, at the end of the calendar month in which the Executive's death occurs, (b) if the Executive's employment is terminated by reason of Total Disability, immediately upon a
determination by the Company of the Executive's Total Disability, and (c) in all other cases, ten (10) days after the date of personal delivery or mailing of the Notice of Termination.
The Executive's employment and performance of services will continue during such ten (10) day period; provided, however, that the Company may, upon notice to the Executive and without reducing
the Executive's compensation during such period, excuse the Executive from any or all of her duties during such period. 


8.     Termination Payments  


        In the event of termination of the Executive's employment during the Employment Period, all compensation and benefits set forth in this Agreement shall terminate
except as specifically provided in this Section 8. 


4





 



        8.1   Termination by the Company Other Than for Cause or by the Executive for Good Reason  


        If during the Employment Period the Company terminates the Executive's employment other than for Cause or the Executive terminates her employment for Good Reason,
the Executive shall be entitled to: 



        (a)   receive
payment of the following accrued obligations (the "Accrued Obligations"): 



        (i)    the
Annual Base Salary through the Date of Termination to the extent not theretofore paid; 


        (ii)   the
product of (x) the Annual Bonus payable with respect to the fiscal year in which the Date of Termination occurs and (y) a fraction the numerator of
which is the number of days in the current fiscal year through the Date of Termination, and the denominator of which is three hundred sixty-five (365); provided that, in the event that the
Executive is entitled to an amount in respect of the Annual Bonus under Section 8.1(c), she shall receive the amount payable under Section 8.1(c) first and the amount payable under this
Section 8.1(a)(ii) only to the extent it exceeds the amount payable under Section 8.1(c); and 


        (iii)  any
compensation previously deferred by the Executive (together with accrued interest or earnings thereon, if any) and any accrued vacation pay that would be payable
under the Company's standard policy, in each case to the extent not theretofore paid; 




        (b)   for
one year after the Date of Termination or until the Executive qualifies for comparable medical and dental insurance benefits from another employer, whichever occurs
first, the Company shall pay the Executive's premiums for health insurance benefit continuation for the Executive and her family members, if applicable, which the Company provides to the Executive
under the provisions of the federal Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA"), to the extent that the Company would
have paid such premiums had the Executive remained employed by the Company (such continued payment is hereinafter referred to as "COBRA Continuation"); 


        (c)   an
amount equal to fifty percent (50%) of the Annual Bonus that would have been paid to the Executive for the fiscal year in which the Date of Termination falls but for
the termination of the Executive's employment; 


        (d)   an
amount as severance pay equal to fifty percent (50%) of the Annual Base Salary for the fiscal year in which the Date of Termination occurs; and 


        (e)   immediate
vesting of all outstanding stock options previously granted to the Executive by the Company. 




        8.2   Termination for Cause or Other Than for Good Reason  


        If during the Employment Period the Executive's employment shall be terminated by the Company for Cause or by the Executive for other than Good Reason, this
Agreement shall terminate without further obligation on the part of the Company to the Executive, other than the Company's obligation to pay the Executive (a) the Annual Base Salary through the
Date of Termination, (b) the amount of any compensation previously deferred by the Executive, and (c) any accrued vacation pay that would be payable under the Company's standard policy,
in each case to the extent theretofore unpaid. 


        8.3   Expiration of Term  


        In the event the Executive's employment is not terminated prior to expiration of the Term, this Agreement shall terminate without further obligation on the part
of the Company to the Executive, other than the Company's obligation to pay the Executive the product of (a) the Annual Bonus payable 


5





 



with
respect to the fiscal year in which the Term expired and (b) a fraction the numerator of which is the number of days in the current fiscal year through the end of the Term and the
denominator of which is three hundred sixty-five (365). 


        8.4   Termination Because of Death or Total Disability  



        If during the Employment Period the Executive's employment is terminated by reason of the Executive's death or Total Disability, this Agreement shall terminate
automatically without further obligation on the part of the Company to the Executive or her legal representatives under this Agreement, other than the Company's obligation to pay the Executive the
Accrued Obligations (which shall be paid to the Executive's estate or beneficiary, as applicable in the case of the Executive's death), and to provide COBRA Continuation. 


        8.5   Payment Schedule  


        All payments of Accrued Obligations, or any portion thereof payable pursuant to this Section 8, shall be made to the Executive within ten
(10) working days of the Date of Termination. Any payments payable to the Executive pursuant to Section 8.1(c) and (d) hereof shall be made to the Executive in a lump sum within
ten (10) working days of the Date of Termination. 


        8.6   Cause  


        For purposes of this Agreement, "Cause" means cause given by the Executive to the Company and shall include,
without limitation, the occurrence of one (1) or more of the following events:

clear refusal to carry out any material lawful duties of the Executive or any directions of the Board or senior management of the Company, all reasonably consistent
with the duties described in Section 3.2 hereof; 


        (b)   persistent
failure to carry out any lawful duties of the Executive described in Section 3.2 hereof or any directions of the Board or senior management reasonably
consistent with the duties herein set forth to be performed by the Executive, provided, however, that the Executive has been given reasonable notice and opportunity to correct any such failure; 



        (c)   violation
by the Executive of a state or federal criminal law involving the commission of a crime against the Company or any other criminal act involving moral
turpitude; 


        (d)   current

compromising the Executive's reputation or ability to represent the Company with investors, customers or the public; or 


        (e)   any
other material violation of any provision of this Agreement by the Executive, subject to the notice and opportunity-to-cure requirements of
Section 11 hereof. 




        8.7   Good Reason  


        For purposes of this Agreement, "Good Reason" means 



        (a)   the
assignment to the Executive of any duties materially inconsistent with the Executive's position, authority, duties or responsibilities as contemplated by
Section 3.2 hereof or any other action by the Company that results in a material diminution in such position, authority, duties or responsibilities, excluding for this purpose an isolated and
inadvertent action not taken in bad faith and that is remedied by the Company promptly after receipt of notice thereof given by the Executive;

        (b)   any

(including stock option plan) would be characterized as an "excess parachute payment" to the Executive under Section 280G of the Internal Revenue Code of 1986, as amended (the
"Code"), the Executive shall be paid any excise tax that the Executive owes under Section 4999 of the Code as a result of such characterization,
such excise tax to be paid to the Executive at least ten (10) days prior to the date that she is obligated to make the excise tax payment. The determination of whether and to what extent any
payments or benefits would be "excess parachute payments" and the date by which any excise tax shall be due, shall be determined in writing by recognized tax counsel selected by the Company and
reasonably acceptable to the Executive. 


9.     Representations, Warranties and Other Conditions  


        In order to induce the Company to enter into this Agreement, the Executive represents and warrants to the Company as follows:

        10.2 Return of Materials  



        All documents, records, notebooks, notes, memoranda, drawings or other documents made or compiled by the Executive at any time, or in her possession, including

17.   Arbitration; Attorneys' Fees  


        Except in connection with enforcing Section 10 hereof, for which legal and equitable remedies may be sought in a court of law, any dispute arising under
this Agreement shall be subject to arbitration. The arbitration proceeding shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association (the
"AAA Rules") then in effect, conducted by one arbitrator either mutually agreed upon or selected in accordance with the AAA Rules. The arbitration shall

        If any provision of this Agreement shall be held invalid, illegal or unenforceable in any jurisdiction, for any reason, including, without limitation, the

9





 



other
provisions hereof shall remain in full force and effect in such jurisdiction and shall be liberally construed in order to carry out the intent of the parties hereto as nearly as may be possible,
(b) such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of any other provision hereof, and (c) any court or arbitrator having
jurisdiction thereover shall have the power to reform such provision to the extent necessary for such provision to be enforceable under applicable law. 


19.   Entire Agreement  


        Except as described in Section 22 hereof, this Agreement constitutes the entire agreement between the Company and the Executive with respect to the subject
matter hereof, and all prior or
contemporaneous oral or written communications, understandings or agreements between the Company and the Executive with respect to such subject matter, including, without limitation, the Change of
Control Agreement, dated March 26, 2002, between the parties, are hereby superseded and nullified in their entireties, except that the Proprietary Information and Invention Agreement between
the Company and the Executive shall continue in full force and effect to the extent not superseded by Section 10 hereof. 


20.   Withholding  



        The Company may withhold from any amounts payable under this Agreement such federal, state or local taxes as shall be required to be withheld pursuant to any
applicable law or regulation. 


21.   Counterparts  


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



22.   Coordination With Severance Agreement  


        The Severance Agreement that the parties are entering into contemporaneously with this Agreement provides for certain forms of severance and benefit payments in
the event of termination of the Executive's employment. This Agreement is in addition to the Severance Agreement and in no way supersedes or nullifies the Severance Agreement. Nevertheless, it is
possible that termination of employment by the Company or by the Executive may fall within the scope of both agreements. In such event, payments made to the Executive under Section 8.1 hereof
shall be coordinated with payments made to the Executive under Section 5.1 of the Severance Agreement as follows: 



        (a)   Accrued
Obligations under this Agreement shall be paid first, in which case Accrued Obligations need not be paid under the Severance Agreement; 


        (b)   COBRA
Continuation under this Agreement shall be provided first, in which case COBRA Continuation need not be provided under the Severance Agreement; and 


        (c)   the
severance payment required under Section 8.1(d) hereof shall be paid first, in which case only that portion of any severance payment required under
Section 5.1(c) of the Severance Agreement in excess of the severance payment required under Section 8.1(d) hereof shall be paid in accordance with the provisions of the Severance
Agreement. 



10





 





        IN
WITNESS WHEREOF, the parties have executed and entered into this Agreement effective on the date first set forth above.

APPENDIX A    
    


        For purposes of this Agreement, a "Change of Control" shall mean: 



        (a)   A
"Board Change" that, for purposes of this Agreement, shall have occurred if a majority (excluding vacant seats) of the
seats on the Board are occupied by individuals who were neither (i) nominated by a majority of the Incumbent Directors nor (ii) appointed by directors so nominated. An
"Incumbent Director" is a member of the Board who has been either (i) nominated by a majority of the directors of the Company then in office or
(ii) appointed by directors so nominated, but excluding, for this purpose, any such individual whose initial assumption of office occurs as a result of either an actual or threatened election
contest (as such terms are used in Rule 14a-11 of Regulation 14A promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange
Act")) or other actual or threatened solicitation of proxies or consents by or on behalf of a Person (as hereinafter defined) other than the Board; or 


        (b)   The
acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) (a
"Person") of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of (i) twenty percent
(20%) or more of either (A) the then outstanding shares of Common Stock of the Company (the "Outstanding Company Common Stock") or (B) the
combined voting power of the then outstanding voting securities of the Company entitled to vote generally in the election of directors (the "Outstanding Company Voting
Securities"), in the case of either (A) or (B) of this clause (i), which acquisition is not approved in advance by a majority of the Incumbent Directors,
or (ii) thirty-three percent (33%) or more of either (A) the Outstanding Company Common Stock or (B) the Outstanding Company Voting Securities, in the case of either (A) or
(B) of this clause (ii), which acquisition is approved in advance by a majority of the Incumbent Directors; provided, however, that the following acquisitions shall not constitute a
Change of Control: (x) any acquisition by the Company, (y) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any corporation
controlled by the Company, or (z) any acquisition by any corporation pursuant to a reorganization, merger or consolidation, if, following such reorganization, merger or consolidation, the
conditions described in clauses (i), (ii) and (iii) of subsection (c) of this Appendix A are satisfied; or 


        (c)   Approval
by the shareholders of the Company of a reorganization, merger or consolidation, in each case, unless, immediately following such reorganization, merger or
consolidation, (i) more than sixty percent (60%) of, respectively, the then outstanding shares of common stock of the corporation resulting from such reorganization, merger or consolidation and
the combined voting power of the then outstanding voting securities of such corporation entitled to vote generally in the election of directors is then beneficially owned, directly or indirectly, by
all or substantially all the individuals and entities who were the beneficial owners, respectively, of the Outstanding Company Common Stock and the Outstanding Company Voting Securities immediately
prior to such reorganization, merger or consolidation in substantially the same proportion as their ownership immediately prior to such reorganization, merger or consolidation of the Outstanding
Company Common Stock and the Outstanding Company Voting Securities, as the case may be, (ii) no Person (excluding the Company, any employee benefit plan (or related trust) of the Company or
such corporation resulting from such reorganization, merger or consolidation and any Person beneficially owning, immediately prior to such reorganization, merger or consolidation, directly or
indirectly, thirty-three percent (33%) or more of the Outstanding Company Common Stock or the Outstanding Company Voting Securities, as the case may be) beneficially owns, directly or indirectly,
thirty-three percent (33%) or more of, respectively, the then outstanding shares of common stock of the corporation resulting from such reorganization, merger or consolidation or the combined voting
power of the then outstanding voting securities of such corporation entitled to vote generally in the election of directors, and (iii) at least a majority

of
the members of the board of directors of the corporation resulting from such reorganization, merger or consolidation were the Incumbent Directors at the time of the execution of the initial
agreement providing for such reorganization, merger or consolidation; or 



        (d)   Approval
by the shareholders of the Company of (i) a complete liquidation or dissolution of the Company or (ii) the sale or other disposition of all or
substantially all the assets of the Company, other than to a corporation with respect to which immediately following such sale or other disposition, (A) more than sixty percent (60%) of,
respectively, the then outstanding shares of common stock of such corporation and the combined voting power of the then outstanding voting securities of such corporation entitled to vote generally in
the election of directors is then beneficially owned, directly or indirectly, by all or substantially all the individuals and entities who were the beneficial owners, respectively, of the Outstanding
Company Common Stock and the Outstanding Company Voting Securities immediately prior to such sale or other disposition in substantially the same proportion as their ownership, immediately prior to
such sale or other disposition, of the Outstanding Company Common Stock and the Outstanding Company Voting Securities, as the case may be, (B) no Person (excluding the Company, any employee
benefit plan (or related trust) of the Company or such corporation and any Person beneficially owning, immediately prior to such sale or other disposition, directly or indirectly, thirty-three percent
(33%) or more of the Outstanding Company Common Stock or the Outstanding Company Voting Securities, as the case may be) beneficially owns, directly or indirectly, thirty-three percent (33%) or more
of, respectively, the then outstanding shares of common stock of such corporation and the combined voting power of the then outstanding voting securities of such corporation entitled to vote generally
in the election of directors, and (C) at least a majority of the members of the board of directors of such corporation were approved by a majority of the Incumbent Directors at the time of the
execution of the initial agreement or action of the Board providing for such sale or other disposition of the Company's assets.
