TAPESTRY PHARMACEUTICALS, INC. 2006 EQUITY INCENTIVEPLAN

1

(a)           In the Company’s sole discretion and provided that at the time of exercise the Common Stock is publicly traded, pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds.

(b)           In the Company’s sole discretion and provided that at the time of exercise the Common Stock is publicly traded, by delivery of already-owned shares of Common Stock either that you have held for the period required to avoid a charge to the Company’s reported earnings (generally six (6) months) or that you did not acquire, directly or indirectly from the Company, that are owned free and clear of any liens, claims, encumbrances or security interests, and that are valued at Fair Market Value on the date of exercise.  “Delivery” for these purposes, in the sole discretion of the Company at the time you exercise your option, shall include delivery to the Company of your attestation of ownership of such shares of Common Stock in a form approved by the Company.  Notwithstanding the foregoing, you may not exercise your option by tender to the Company of Common Stock to the extent such tender would violate the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock.

(c)           In the Company’s sole discretion and provided that at the time of exercise the Common Stock is publicly traded, through a “net exercise” of your option, pursuant to which the Company will not require payment of the exercise price of your option but will reduce the number of shares of Common Stock issued to you upon the exercise by the largest number of whole shares that has a Fair Market Value that does not exceed the aggregate exercise price.  With respect to any remaining balance of the aggregate exercise price, you shall make a cash payment to the Company.  The shares of Common Stock so used to pay the exercise price of your option under a “net exercise” will be considered to have resulted from the exercise of the option, and accordingly, the option will not again be exercisable with respect to such shares, the shares actually delivered to you, and any shares withheld for purposes of tax withholding.

(d)           In the Company’s sole discretion and subject to compliance with applicable law (including Section 402 of the Sarbanes Oxley Act of 2002), pursuant to the following deferred payment alternative:

(i)            Not less than one hundred percent (100%) of the aggregate exercise price, plus accrued interest, shall be due four (4) years from date of exercise or, at the Company’s election, upon termination of your Continuous Service.

(ii)           Interest shall be compounded at least annually and shall be charged at the minimum rate of interest necessary to avoid (1) the treatment as interest, under any applicable provisions of the Code, of any amounts other than amounts stated to be interest under the deferred payment arrangement and (2) the treatment of the option as a variable award for financial accounting purposes.

(iii)         At any time that the Company is incorporated in Delaware, payment of the Common Stock’s “par value,” as defined in the Delaware General Corporation Law, shall be made in cash and not by deferred payment.

2

(iv)          In order to elect the deferred payment alternative, you must, as a part of your written notice of exercise, give notice of the election of this payment alternative and, in order to secure the payment of the deferred exercise price to the Company hereunder, if the Company so requests, you must tender to the Company a promissory note and a pledge agreement covering the purchased shares of Common Stock, both in form and substance satisfactory to the Company, or such other or additional documentation as the Company may request.

5.             WHOLE SHARES.  You may exercise your option only for whole shares of Common Stock.

6.             SECURITIES LAW COMPLIANCE.  Notwithstanding anything to the contrary contained herein, you may not exercise your option unless the shares of Common Stock issuable upon such exercise are then registered under the Securities Act or, if such shares of Common Stock are not then so registered, the Company has determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act.  The exercise of your option also must comply with other applicable laws and regulations governing your option, and you may not exercise your option if the Company determines that such exercise would not be in material compliance with such laws and regulations.

7.             TERM.  You may not exercise your option before the commencement or after the expiration of its term.  The term of your option commences on the Date of Grant and expires upon the earliest of the following:

(a)           one hundred eighty (180) days after the termination of your Continuous Service for any reason other than your Disability or death, provided that if during any part of such period your option is not exercisable solely because of the condition set forth in Section 6, your option shall not expire until the earlier of the Expiration Date (as defined in your Grant Notice) or until it shall have been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service;

(b)           twelve (12) months after the termination of your Continuous Service due to your Disability;

(c)           eighteen (18) months after your death if you die either during your Continuous Service or within one hundred eighty (180) days after your Continuous Service terminates;

(d)           the Expiration Date indicated in your Grant Notice;

(e)           in accordance with the provisions of Section 12 of the Plan; or

(f)            the day before the tenth (10th) anniversary of the Date of Grant (as defined in your Grant Notice).

8.             EXERCISE.

(a)           You may exercise the vested portion of your option (and the unvested portion of your option if your Grant Notice so permits) during its term by delivering a Notice of Exercise (in a form designated by the Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with such additional documents as the Company may then require.

(b)           By exercising your option you agree that, as a condition to any exercise of your option, the Company may require you to enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (1) the exercise of your option, (2) the lapse of any substantial risk of forfeiture to which the shares of Common Stock are subject at the time of exercise, or (3) the disposition of shares of Common Stock acquired upon such exercise.

9.             TRANSFERABILITY.  Your option is not transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you.  Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your death, shall thereafter be entitled to exercise your option.

10.          CHANGE IN CONTROL.

(a)           If a Change in Control occurs and as of, or within [25 months, for Named Executive Officers][13 months, for Controller and other officers Vice President and above] after, the effective time of such Change in Control your Continuous Service terminates due to an involuntary termination (not including death or Disability) without Cause or due to a voluntary termination with Good Reason, then, as of the date of termination of Continuous Service, the vesting and exercisability of your option shall be accelerated in full.

(b)           “Cause” means the occurrence of any one or more of the following: (i) your commission of any crime involving fraud, dishonesty or moral turpitude; (ii) your attempted commission of or participation in a fraud or act of dishonesty against the Company that results in (or might have reasonably resulted in) material harm to the business of the Company; (iii) your intentional, material violation of any contract or agreement between you and the Company or any statutory duty you owe to the Company; or (iv) your conduct that constitutes gross insubordination, incompetence or habitual neglect of duties and that results in (or might have reasonably resulted in) material harm to the business of the Company; provided, however, that the action or conduct described in clauses (iii) and (iv) above will constitute “Cause” only if such action or conduct continues after the Company has provided you with written notice thereof and thirty (30) days to cure the same.

(c)           “Good Reason” means that one or more of the following are undertaken by the Company without your express written consent: (i) the assignment to you of any duties or responsibilities that results in a material diminution in your function as in effect immediately prior to the effective date of the Change in Control; (ii) a reduction by the Company in your annual base salary, as in effect on the effective date of the Change in Control or as increased thereafter; (iii) any failure by the Company to continue in effect any benefit plan or program, including incentive plans or plans with respect to the receipt of securities of the Company, in

4

which you were participating immediately prior to the effective date of the Change in Control (hereinafter referred to as “Benefit Plans”), or the taking of any action by the Company that would adversely affect your participation in or reduce your benefits under the Benefit Plans or deprive you of any fringe benefit that you enjoyed immediately prior to the effective date of the Change in Control; provided, however, that Good Reason shall not be deemed to have occurred if the Company provides for your participation in benefit plans and programs that, taken as a whole, are comparable to the Benefit Plans; (iv) a relocation of your business office to a location more than fifty (50) miles from the location at which you performed your duties as of the effective date of the Change in Control, except for required travel by you on the Company’s business to an extent substantially consistent with your business travel obligations prior to the effective date of the Change in Control; or (v) a material breach by the Company of any provision of the Plan or the Option Agreement or any other material agreement between you and the Company concerning the terms and conditions of your employment.

(d)           If any payment or benefit you would receive pursuant to a Change in Control from the Company or otherwise (“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be equal to the Reduced Amount. The “Reduced Amount” shall be either (x) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment, whichever amount, after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in your receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment equals the Reduced Amount, reduction shall occur in the following order unless you elect in writing a different order (provided, however, that such election shall be subject to Company approval if made on or after the effective date of the event that triggers the Payment): reduction of cash payments; cancellation of accelerated vesting of Stock Awards; reduction of employee benefits. In the event that acceleration of vesting of Stock Award compensation is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant of your Stock Awards (i.e., earliest granted Stock Award cancelled last) unless you elect in writing a different order for cancellation.

The accounting firm engaged by the Company for general audit purposes as of the day prior to the effective date of the Change in Control shall perform the foregoing calculations. If the accounting firm so engaged by the Company is serving as accountant or auditor for the individual, entity or group effecting the Change in Control, the Company shall appoint a nationally recognized accounting firm to make the determinations required hereunder. The Company shall bear all expenses with respect to the determinations by such accounting firm required to be made hereunder.

The accounting firm engaged to make the determinations hereunder shall provide its calculations, together with detailed supporting documentation, to you and the Company within fifteen (15) calendar days after the date on which your right to a Payment is triggered (if requested at that time by you or the Company) or such other time as requested by you or the

5

Company. If the accounting firm determines that no Excise Tax is payable with respect to a Payment, either before or after the application of the Reduced Amount, it shall furnish you and the Company with an opinion reasonably acceptable to you that no Excise Tax will be imposed with respect to such Payment. Any good faith determinations of the accounting firm made hereunder shall be final, binding and conclusive upon you and the Company.

11.          OPTION NOT A SERVICE CONTRACT.  Your option is not an employment or service contract, and nothing in your option shall be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an Affiliate, or of the Company or an Affiliate to continue your employment.  In addition, nothing in your option shall obligate the Company or an Affiliate, their respective stockholders, Boards of Directors, Officers or Employees to continue any relationship that you might have as a Director or Consultant for the Company or an Affiliate.

12.          WITHHOLDING OBLIGATIONS.

(a)           At the time you exercise your option, in whole or in part, or at any time thereafter as requested by the Company, you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a “cashless exercise” pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with the exercise of your option.

(b)           Upon your request and subject to approval by the Company, in its sole discretion, and compliance with any applicable legal conditions or restrictions, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole shares of Common Stock having a Fair Market Value, determined by the Company as of the date of exercise, not in excess of the minimum amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid variable award accounting).  If the date of determination of any tax withholding obligation is deferred to a date later than the date of exercise of your option, share withholding pursuant to the preceding sentence shall not be permitted unless you make a proper and timely election under Section 83(b) of the Code, covering the aggregate number of shares of Common Stock acquired upon such exercise with respect to which such determination is otherwise deferred, to accelerate the determination of such tax withholding obligation to the date of exercise of your option.  Notwithstanding the filing of such election, shares of Common Stock shall be withheld solely from fully vested shares of Common Stock determined as of the date of exercise of your option that are otherwise issuable to you upon such exercise.  Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility.

(c)           You may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate are satisfied.  Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company shall have no obligation to issue a certificate for such shares of Common Stock or release such shares of Common Stock from any escrow provided for herein unless such obligations are satisfied.

13.          NOTICES.  Any notices provided for in your option or the Plan shall be given in writing and shall be deemed effectively given upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address you provided to the Company.

14.          GOVERNING PLAN DOCUMENT.  Your option is subject to all the provisions of the Plan, the provisions of which are hereby made a part of your option, and is further subject to all interpretations, amendments, rules and regulations, which may from time to time be promulgated and adopted pursuant to the Plan.  In the event of any conflict between the provisions of your option and those of the Plan, the provisions of the Plan shall control.
