Amended Executive Change in Control and Severance Benefit Plan



 Exhibit 10.67 
 NUVELO, INC. 
 EXECUTIVE CHANGE IN CONTROL AND SEVERANCE BENEFIT PLAN 
 As Amended August 1, 2007 (the “Amendment Date”). 
  

	1.	INTRODUCTION 

 The Nuvelo, Inc.
Executive Change in Control and Severance Benefit Plan (the “Plan”), as established effective December 14, 2004 (the “Effective Date”) and amended from time to time, is intended to provide for the payment of severance
benefits and/or change in control benefits to certain eligible employees of Nuvelo, Inc. and its wholly owned subsidiaries (collectively, “Nuvelo”). The Plan supersedes and replaces in its entirety any change in control and/or severance
arrangement adopted by Nuvelo. This Plan also is intended to supersede any unwritten severance plan, policy, or practice of Nuvelo and any unwritten change of control plan, policy or practice of Nuvelo. However, except as provided herein, this Plan
does not supersede any written agreement between Nuvelo and any employee that provides for payments or benefits in the event of termination of employment or a change in control of Nuvelo. This Plan may, however, provide for certain offsets or
reduction of benefits under this Plan on account of such other benefits. This document also is the Summary Plan Description for the Plan. 
  

	2.	DEFINITIONS. 

 For purposes of the
Plan, the following terms are defined as follows: 
 (a) “Alternative Benefits” means Covered Benefits that are provided by
a program, plan, agreement, or arrangement other than this Plan. Accordingly, for example, an “Alternative Cash Severance Benefit” means a Cash Severance Benefit that is an Alternative Benefit and an “Alternative Continued Medical
Benefit” means a Continued Medical Benefit that is an Alternative Benefit. Notwithstanding the foregoing, a benefit that is designated an Alternative Benefit in a Participant’s Participation Notice shall be deemed to be an Alternative
Benefit with respect to such Participant, and a benefit that is designated as not an Alternative Benefit in a Participant’s Participation Notice shall not be deemed to be an Alternative Benefit with respect to such Participant. Any benefit
provided to a Participant other than by this Plan which is not addressed in the Participant’s Participation Notice shall be deemed to be an Alternative Benefit if such benefit is described in the first sentence of this Section 2(a).

 (b) “Base Salary Amount” means the greater of (i) the Participant’s base salary as determined on a monthly
basis at the time of the Covered Termination multiplied by twelve (12), or (ii) the greatest amount of base salary received by the Participant in any consecutive twelve (12) month period that occurred within the thirty-six (36) month
period immediately preceding the Covered Termination. For clarity purposes, any amount that a Participant elects to have withheld from the Participant’s base salary, for example, contributions to any current or future plan qualified under
Section 401(k) of the Code or any nonqualified deferred compensation plan (collectively “Elective Deferral Plans”) shall not reduce the Participant’s Base Salary Amount. 







 (c) “Base Severance Benefit” means the Participant’s Base Salary Amount. Except as
may be set forth in the Participant’s Participation Notice, in the event the Participant has received, or is entitled to and has not waived, an Alternative Cash Severance Benefit, the Base Severance Benefit shall be reduced (but not below zero)
by the amount of the Alternative Cash Severance Benefit. 
 (d) “Board” means the Board of Directors of Nuvelo. 

(e) “Bonus Amount” means the highest level of Bonuses Received by the Participant in any consecutive eleven (11) month period
that occurred within the thirty-six (36) month period immediately preceding the Covered Termination. “Bonuses Received” means any cash bonuses paid to a Participant pursuant to a cash bonus plan or program and shall not include, for
example, amounts received pursuant to restricted stock, restricted stock units, or stock appreciation rights whether or not such awards are paid or settled in cash. 
 (f) “Bonus Severance Benefit” means the Participant’s Bonus Amount. Except as may be set forth in the Participant’s Participation Notice, in the event the Participant has received, or is
entitled to and has not waived, an Alternative Cash Severance Benefit, the Bonus Severance Benefit shall be reduced (but not below zero) by the amount of the excess, if any, of Alternative Cash Severance Benefit over the Base Severance Benefit.

 (g) “Change in Control” is defined as one or more of the following events: 
 (i) there is consummated a sale or other disposition of all or substantially all of the assets of Nuvelo, as determined on a
consolidated basis (other than a sale to an entity where at least fifty percent (50%) of the combined voting power of the voting securities of such entity are owned by the stockholders of Nuvelo immediately after such sale or other disposition
in substantially the same proportions as their ownership of Nuvelo immediately prior to such sale or other disposition); or 
 (ii) there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) Nuvelo, and, immediately after the consummation of such transaction, the stockholders of Nuvelo immediately prior to the
consummation of such transaction do not directly or indirectly own, immediately after the consummation of such transaction, outstanding voting securities representing at least fifty percent (50%) of the combined outstanding voting power of the
surviving entity in such transaction or at least fifty percent (50%) of the combined outstanding voting power of the parent of the surviving entity in such transaction, in each case in substantially the same proportions as their ownership of
Nuvelo immediately prior to such transaction; or 
 (iii) any person, entity or group (other than Nuvelo, a subsidiary
or affiliate of Nuvelo, or a Nuvelo employee benefit plan, including any trustee of such plan acting as trustee) becomes the beneficial owner, directly or indirectly, of securities of Nuvelo representing at least fifty percent (50%) of the
combined voting power of Nuvelo’s then-outstanding securities, other than by virtue of a merger, consolidation or similar transaction; or 







 (iv) the individuals who, at the beginning of any period of twelve
(12) months or less, constituted the Board of Directors of Nuvelo cease, for any reason, to constitute at least a majority thereof, unless the election or nomination for election of each new director was approved by the vote of at least a
majority of the directors then still in office who were directors at the beginning of such period. 
 (h) “Change in Control
Severance” means any Covered Termination of a Participant that occurs during the one (1) month prior to or during the twelve (12) months after a Change in Control. 
 (i) “Code” means the Internal Revenue Code of 1986, as amended. 
 (j) “Constructive Termination” means the Participant’s resignation from all positions he or she then holds with Nuvelo if one or
more of the following events occur without the Participant’s express written consent: 
 (i) the assignment to the
Participant of duties or responsibilities that results in a material diminution in the Participant’s authority, duties, position, status, or responsibilities with Nuvelo as in effect at any time during the twelve (12) month period
preceding such assignment; 
 (ii) a material reduction in the Participant’s base salary; 
 (iii) a change in the Participant’s business location that results in a round trip increase in the Participant’s daily
commute of more than 35 miles, except for required travel for Nuvelo’s business to an extent substantially consistent with Participant’s prior business travel obligations; 
 (iv) a material breach by Nuvelo of any provisions of the Plan or any enforceable written agreement between Nuvelo and the
Participant; or 
 (v) any failure by Nuvelo to obtain assumption of the Plan by any successor to, or assignee of,
Nuvelo. 
 Notwithstanding the foregoing, a voluntary termination shall not be deemed a Constructive Termination unless (x) the
Participant provides Nuvelo with written notice (the “Constructive Termination Notice”) that the Participant believes that an event described in this Section 2(j) has occurred, (y) the Constructive Termination Notice is given
within thirty (30) days after the date the event occurred, and (z) Nuvelo does not rescind or cure the conduct giving rise to the event described in this Section 2(j) within thirty (30) days of receipt by Nuvelo of the
Constructive Termination Notice, in which case the date of Constructive Termination shall be deemed the date on which that thirty (30) day period expires. 
 (k) “Continuation Period” means the twelve (12) month period running from the date of the Covered Termination. 
 (l) “Continued Medical Benefits” means the Nuvelo’s contributions toward the cost of continuation coverage under COBRA as provided under Sections 5(c) and 6(d). 







 (m) “Covered Benefits” means the following benefits: (i) Base Severance Benefit,
(ii) Bonus Severance Benefit, (iii) Continued Medical Benefits and (iv) accelerated vesting of Nuvelo Stock Awards. 
 (n)
“Covered Termination” means an Involuntary Termination Without Cause or a Constructive Termination. Termination of employment of a Participant due to death or disability shall not constitute a Covered Termination unless a voluntary
termination of employment by the Participant immediately prior to the Participant’s death or disability would have qualified as a Constructive Termination. 
 (o) “Eligible Employee” means all executive employees at the level of Vice President of Nuvelo or above. In addition to the foregoing, “Eligible Employee” means any other current or former
employee of Nuvelo (x) who has been designated by the Board as eligible for benefits under the Plan and (y) whose highest seniority level was at least the equivalent of a Vice President; provided, however, that the Board shall not
designate more than ninety-nine (99) persons as Eligible Employees at any one time. 
 (p) “ERISA” means the Employee
Retirement Income Security Act of 1974, as amended. 
 (q) “Involuntary Termination Without Cause” means an involuntary
termination of employment by Nuvelo other than for one of the following reasons: 
 (i) a refusal or failure to follow
the lawful and reasonable directions of the Board or individual to whom the Participant reports, which refusal or failure is not cured within 30 days following delivery of written notice of such conduct to the Participant; 
 (ii) a material failure by the Participant to perform his or her duties in a manner reasonably satisfactory to the Board that is
not cured within 30 days following delivery of written notice of such failure to the Participant; or 
 (iii)
participation in, a conviction of, or a plea of guilty or nolo contendere to a felony or any crime involving moral turpitude, fraud, or dishonesty that is likely to have or has had a material adverse effect on Nuvelo. 
 Termination of employment of a Participant due to death or disability shall not constitute an Involuntary Termination. 
 (r) “Option” means any and all options granted to a Participant by Nuvelo, in exchange for the performance of services, to acquire
common stock of Nuvelo, other than any options granted to a Participant which expressly provide that this Plan shall not apply to such option. 
 (s) “Participant” means an Eligible Employee who has received a Participation Notice that the employee is eligible to receive benefits pursuant to this Plan. 
 (t) “Participation Notice” means the latest notice delivered by Nuvelo to an Eligible Employee informing the employee that the employee
is eligible for Covered Benefits. A Participation Notice shall be in such form as may be determined by Nuvelo. Notwithstanding the 








 
foregoing, neither Nuvelo nor any successor may amend a Participation Notice in any way that is adverse to a Participant, without the written consent of the
Participant, unless (x) the amendment is made more than six (6) months prior to an applicable Covered Termination or Change in Control and (y) the amendment does not reduce any benefits the Participant would receive under the Plan to
an amount that is less than the benefits the Participant would receive if the amended Participation Notice did not address such benefit. 
 (u) “Plan Administrator” means the Board or any committee duly authorized by the Board to administer the Plan. The Plan Administrator may be, but is not required to be, the Compensation Committee of the Board. The Board may
at any time administer the Plan, in whole or in part, notwithstanding that the Board has previously appointed a committee to act as the Plan Administrator. 
 (v) “Regular Severance” means any Covered Termination that is not a Change in Control Severance. 
 (w) “Stock Award” means any and all compensatory stock awards (including Options) and stock rights (including, without limitation, restricted stock, restricted stock units and stock appreciation rights) granted to a
Participant with respect to Nuvelo stock in exchange for services rendered or to be rendered to Nuvelo and which entitle the Participant to receive either common stock of Nuvelo or some other pecuniary benefit determined by reference to Nuvelo
common stock, other than any stock awards granted to a Participant which expressly provide that this Plan shall not apply to such Stock Awards. 
 (x) “Vested” means that the Stock Award is, in the case of an Option, exercisable in full and, in the case of all other Stock Awards, that the Stock Award is not subject to Nuvelo’s right (whether conditional or
unconditional) to reacquire the Stock Award due to forfeiture or repurchase at less than the fair market value of the stock or Stock Award. 
  

	3.	ELIGIBILITY FOR BENEFITS. 

 (a) General Rules. Subject to the provisions set forth in this Section and Section 7, in the event of a Change in Control, Nuvelo will provide the Change in Control benefits described in Sections 4 and 5
of the Plan to the affected Participants. Subject to the provisions set forth in this Section and Section 7, in the event of a Regular Severance, Nuvelo will provide the severance benefits described in Section 6 of the Plan to the affected
Participant. 
 (b) Exceptions to Benefit Entitlement. An employee who otherwise is a Participant will not receive benefits under the
Plan in any of the following circumstances, as determined by Nuvelo in its sole discretion: 
 (i) The employee
voluntarily terminates employment with Nuvelo in order to accept employment with another entity that is controlled (directly or indirectly) by Nuvelo or is otherwise an affiliate of Nuvelo. 
 (ii) The Participant does not confirm in writing that Participant shall be subject to Nuvelo’s Confidential Information
Agreement (and any other proprietary information or confidentiality agreement of similar effect). 







 (iii) Except as may be set forth in a Participant’s Participation Notice, the
Participant shall not be entitled to receive the benefits set forth in Sections 5(c) or 6(d) if the Participant has either (i) previously received an Alternative Continued Medical Benefit or (ii) is eligible for and has not waived an
Alternative Continued Medical Benefit. 
 (iv) The Participant refuses to execute and let become effective, within the
time period provided by Nuvelo, the release of claims described in Section 7 below. 
 (v) The Participant has not
returned all Nuvelo property which he or she has had in his or her possession at any time, including but not limited to any materials which contain or embody any Nuvelo proprietary or confidential information and any computers, mobile telephones and
other physical property. 
 (c) Termination of Benefits. A Participant’s right to receive the payment of benefits under this Plan
shall terminate immediately if, at any time prior to, or during, the Continuation Period, the Participant, without the prior written approval of Nuvelo: 
 (i) willfully breaches a material provision of the Participant’s Confidential Information Agreement (or any other proprietary information or confidentiality agreement of similar effect); 
 (ii) encourages or solicits any of Nuvelo’s then-current employees to leave Nuvelo’s employ for any reason or interferes
in any other manner with employment relationships at the time existing between Nuvelo and its then-current employees; 
 (iii) induces any of Nuvelo’s then-current clients, customers, suppliers, vendors, distributors, licensors, licensees, or other third parties to terminate their existing business relationship with Nuvelo or interferes in any
other manner with any existing business relationship between Nuvelo and any then-current client, customer, supplier, vendor, distributor, licensor, licensee or other third party. 
  

	4.	CHANGE IN CONTROL STOCK AWARD VESTING BENEFITS


 In the event of a Change in Control, a Participant shall receive the following benefits in respect of any Stock Awards
which remain outstanding as of immediately prior to the effective time of the Change in Control (the “Effective Time”): 
 (a)
Change in Control Vesting Benefit. If the Participant is still employed as of the Effective Time, to the extent the Participant holds any Stock Award that is not fully Vested, one hundred percent (100%) of each Stock Award shall become
Vested as of immediately prior to the Effective Time. 
 (b) Vesting Benefit for Covered Termination Preceding Change in Control. If
the Participant is not employed as of the Effective Time but the Participant’s employment terminated pursuant to a Covered Termination during the one (1) month period ending on the Effective Time, the Stock Awards held by the Participant
that were not Vested on the date of the Participant’s Covered Termination shall become Vested as of immediately prior to the Effective Time. 







 (c) Coordination with Outstanding Stock Awards. In the event the provisions of this Section 4
would adversely affect a Stock Award outstanding on the Amendment Date, this Section 4 shall not apply to such Stock Award without the consent of the Participant. 
  


	5.	CHANGE IN CONTROL SEVERANCE BENEFITS 

 (a) Change in Control Severance Benefits. Upon a Change in Control Severance, and subject to the conditions described in Section 3, such
Participant shall receive the benefits described in Sections 5(b) and 5(c). Any amounts paid pursuant to this Section 5 shall be subject to all income tax and employment tax withholding requirements as well as any other applicable withholding
requirements. 
 (b) Cash Severance Benefits. The Participant who incurred such Change in Control Severance shall receive the Base
Severance Benefit and the Bonus Severance Benefit. 
 (c) Continued Medical Benefits. Provided that the Participant timely elects
continued coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985 (together with any state laws of similar effect, “COBRA”), Nuvelo shall pay for the Continuation Period (or such earlier date as the Participant and his or
her dependents are no longer eligible for COBRA coverage) the portion of premiums of the Participant’s group medical, dental, and vision coverage, including coverage for the Participant’s eligible dependents, that Nuvelo paid prior to the
Change in Control Severance; provided, however, that no such premium payments (or any other payments for medical, dental or vision coverage by Nuvelo) shall be made following the effective date of the Participant’s coverage by a medical,
dental or vision insurance plan of a subsequent employer or after the date the Participant or his or her eligible dependents otherwise cease to be eligible for COBRA coverage. Each Participant shall be required to notify Nuvelo immediately if the
Participant becomes covered by a medical, dental or vision insurance plan of a subsequent employer. No provision of this Plan will affect the continuation coverage rules under COBRA, except that Nuvelo’s payment of any applicable insurance
premiums during the Continuation Period will be credited as payment by the Participant for purposes of the Participant’s payment required under COBRA. Therefore, the period during which a Participant may elect whether or not to continue
Nuvelo’s group medical, dental or vision coverage under COBRA, the length of time during which COBRA continuation coverage will be made available to the Participant, and all other rights and obligations of the Participant under COBRA will be
applied in the same manner that such rules would apply in the absence of this Plan. At the conclusion of the Continuation Period, the Participant will be responsible for the entire payment of premiums required under COBRA for the remainder, if any,
of the COBRA continuation period. For purposes of this Section 5(c), applicable premiums paid by Nuvelo during the Continuation Period shall not include any amounts payable by the Participant under a Section 125 health care reimbursement
plan, which amounts, if any, are the sole responsibility of the Participant. Nuvelo’s sole obligation pursuant to this Section 5(c) is to pay the portion of the premium described above for any COBRA coverage during the Continuation Period.
If the Participant or his spouse or his dependents cannot remain eligible for continued COBRA coverage for the entire Continuation Period, Nuvelo shall have no obligation to provide individual medical, dental, and vision coverage for the
individual(s) who cease to be so eligible for the remainder of the Continuation Period. 








	6.	REGULAR SEVERANCE BENEFITS. 

 (a) Regular Severance Benefit. Upon a Regular Severance, and subject to the conditions described in Section 3, such Participant shall receive the benefits described in Sections 6(b) – 6(d), below. Any
amounts paid pursuant to this Section 6 shall be subject to all income tax and employment tax withholding requirements as well as any other applicable withholding requirements. 
 (b) Base Severance Benefit. The Participant who incurred the Regular Severance shall begin to receive from Nuvelo the Base Severance Benefit.

 (c) Credit Toward Vesting Requirements. With respect to any Stock Awards that are outstanding on the date of the Regular Severance,
the Participant shall be immediately credited with an additional twelve (12) months of service for the purposes of determining the portions of such Stock Awards that are Vested. 
 (d) Continued Medical Benefits. Provided that the Participant timely elects continued coverage under COBRA, Nuvelo shall pay for the Continuation
Period (or such earlier date as the Participant and his or her dependents are no longer eligible for COBRA coverage) the portion of premiums of the Participant’s group medical, dental, and vision coverage, including coverage for the
Participant’s eligible dependents, that Nuvelo paid prior to the Change in Control Severance; provided, however, that no such premium payments (or any other payments for medical, dental or vision coverage by Nuvelo) shall be made
following the effective date of the Participant’s coverage by a medical, dental or vision insurance plan of a subsequent employer or after the date the Participant or his or her eligible dependents otherwise cease to be eligible for COBRA
coverage. Each Participant shall be required to notify Nuvelo immediately if the Participant becomes covered by a medical, dental or vision insurance plan of a subsequent employer. No provision of this Plan will affect the continuation coverage
rules under COBRA, except that Nuvelo’s payment of any applicable insurance premiums during the Continuation Period will be credited as payment by the Participant for purposes of the Participant’s payment required under COBRA. Therefore,
the period during which a Participant may elect whether or not to continue Nuvelo’s group medical, dental or vision coverage under COBRA, the length of time during which COBRA continuation coverage will be made available to the Participant, and
all other rights and obligations of the Participant under COBRA will be applied in the same manner that such rules would apply in the absence of this Plan. At the conclusion of the Continuation Period, the Participant will be responsible for the
entire payment of premiums required under COBRA for the remainder, if any, of the COBRA continuation period. For purposes of this Section 6(d), applicable premiums paid by Nuvelo during the Continuation Period shall not include any amounts
payable by the Participant under a Section 125 health care reimbursement plan, which amounts, if any, are the sole responsibility of the Participant. Nuvelo’s sole obligation pursuant to this Section 6(d) is to pay the portion of the
premium described above for any COBRA coverage during the Continuation Period. If the Participant or his spouse or his dependents cannot remain eligible for continued COBRA coverage for the entire Continuation Period, Nuvelo shall have no obligation
to provide individual medical, dental, and vision coverage for the individual(s) who cease to be so eligible for the remainder of the Continuation Period. 








	7.	LIMITATIONS ON BENEFITS 

 (a) Release. In order to be eligible to receive benefits under Sections 3, 4, 5, and 6 of the Plan, a Participant (or, in the case of the Participant’s death or disability, the Participant’s legal
representative) must execute a general waiver and release in the form generally in use by Nuvelo at the time of such Covered Termination or Change in Control within the time provided by the Company (which time period shall generally not exceed 45
days from the date on which the Participant receives the form of release) and allow such release to become effective in accordance with its terms (such effective date, the “Release Date”). Nuvelo, in its sole discretion, may modify the
form of the required release to comply with applicable federal and state law and shall determine the form of the required release. 
 (b)
Timing of Payments. Any Base Severance Benefit and Bonus Severance Benefit to which a Participant is entitled shall be paid in substantially equal installments over the Continuation Period in accordance with Nuvelo’s normal payroll pay
cycle, commencing with the first regular payroll pay date after the date of termination; provided, however, that no installments shall be paid prior to the Release Date (as defined below), and any installments that would have been paid
through the Release Date shall instead be paid in a lump sum on the first regular payroll pay date on or after the Release Date, with the balance of the installments paid in accordance with the regular payroll pay cycle thereafter. 
 (c) Certain Reductions and Offsets. Notwithstanding any other provision of the Plan to the contrary, a Covered Benefit payable to a Participant
under this Plan shall be reduced (but not below zero) by any Alternative Benefit to such Covered Benefit payable by Nuvelo to such individual under any other policy, plan, program or arrangement, including, without limitation, a contract between the
Participant and any entity, covering such individual. Furthermore, to the extent that any federal, state or local laws, including, without limitation, so-called “plant closing” laws or statutory severance requirements, require Nuvelo to
give advance notice or make a payment of any kind to a Participant because of that Participant’s involuntary termination due to a layoff, reduction in force, plant or facility closing, sale of business, change in control, or any other similar
event or reason, the benefits payable under this Plan shall be paid in satisfaction of any and all such statutory obligations. The benefits provided under this Plan are intended to satisfy any and all statutory obligations that may arise out of a
Participant’s involuntary termination of employment for the foregoing reasons, and the Plan Administrator shall so construe and implement the terms of the Plan. 
 (d) Mitigation. Except as otherwise specifically provided herein, a Participant shall not be required to mitigate damages or the amount of any payment provided under this Plan by seeking other employment or
otherwise, nor shall the amount of any payment provided for under this Plan (other than the Continued Medical Benefits) be reduced by any compensation earned by a Participant as a result of employment by another employer or any retirement benefits
received by such Participant after the date of the Participant’s termination of employment with Nuvelo. 
 (e) Non-Duplication of
Benefits. Except as otherwise specifically provided for herein, no Participant is eligible to receive benefits under this Plan more than one time. This Plan is designed to provide certain severance pay and change of control benefits to
Participants pursuant to the terms and conditions set forth in this Plan and any associated Participation Notice. The 








 
payments pursuant to this Plan are in addition to, and not in lieu of, any unpaid earned salary, bonuses or benefits to which a Participant may be entitled
for the period ending with the Participant’s Covered Termination and/or a Change in Control. 
 (f) Indebtedness of Participants.
If a terminating employee is indebted to Nuvelo or an affiliate of Nuvelo at his or her termination date, Nuvelo reserves the right to offset any Covered Benefits under the Plan by the amount of such indebtedness. 
 (g) Parachute Payments. 
 (i) Best-After Tax Result. If any payment or benefit a Participant would receive, from Nuvelo or otherwise, whether or not pursuant to this Plan, in connection with a Change in Control (a “Payment”), would be subject to the
excise tax imposed by Section 4999 of the Code, or any comparable federal, state, or local excise tax (such excise taxes, together with any related interest and penalties, are hereinafter collectively referred to as the “Excise Tax”),
then the Participant shall be entitled to receive 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 the Participant’s 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 the Participant elects in writing a different order (provided, however, that
such election shall be subject to Company approval if made on or after the date on which the event that triggers the Payment occurs): reduction of cash payments; cancellation of accelerated vesting of stock awards; and 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 the Participant’s stock awards unless the Participant
elects in writing a different order for cancellation. 
 (ii) Use of Third Party Expert. The accounting firm engaged by
Nuvelo for the purpose of rendering general tax advice as of the day prior to the effective date of the Change in Control shall perform the calculations required by this Section 7(g). If the accounting firm so engaged by Nuvelo is serving as
accountant or auditor for the individual, entity, or group effecting the Change in Control, Nuvelo shall appoint a nationally recognized accounting firm to make the determinations required hereunder. Nuvelo 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 Nuvelo and the Participant
within fifteen (15) calendar days after the date on which the Participant’s right to a Payment is triggered (if requested at that time by Nuvelo or the Participant) or such other time as requested by Nuvelo or the Participant. If the
accounting firm determines that no Excise Tax is payable with respect to a Payment to a Participant, it shall furnish Nuvelo and the Participant with an opinion reasonably acceptable to Participant 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 Nuvelo and the Participant. 







 (h) Application of Section 409A. If Nuvelo (or, if applicable, the successor entity thereto)
determines that the payments and benefits provided under the Plan (the “Plan Payments”) constitute “deferred compensation” under Code Section 409A (together, with any state law of similar effect,
“Section 409A”) and a Participant is a “specified employee” of Nuvelo or any successor entity thereto, as such term is defined in Section 409A(a)(2)(B)(i) (a “Specified Employee”), then,
solely to the extent necessary to avoid the incurrence of the adverse personal tax consequences under Section 409A, the timing of the Plan Payments shall be delayed as follows: on the earliest to occur of (i) the date that is six months
and one day after the termination date, (ii) the date of the Participant’s death, or (iii) such earlier date, as reasonably determined in good faith by Nuvelo (or any successor entity thereto), as would not result in any of the Plan
Payments being subject to adverse personal tax consequences under Section 409A, (such earliest date, the “Delayed Initial Payment Date”), Nuvelo (or the successor entity thereto, as applicable) shall (A) pay to the
Participant a lump sum amount equal to the sum of the Plan Payments that the Participant would otherwise have received through the Delayed Initial Payment Date (including reimbursement for any premiums paid by the Participant for health insurance
coverage under COBRA) if the commencement of the payment of the Plan Payments had not been delayed pursuant to this Section 7(h) and (B) commence paying the balance of the Plan Payments in accordance with the applicable payment schedules
set forth above. For the avoidance of doubt, it is intended that (1) each installment of Covered Benefits is a separate “payment” for purposes of Section 409A, (2) all Plan Payments satisfy, to the greatest extent possible,
the exemptions from the application of Section 409A provided under of Treasury Regulation 1.409A-1(b)(4) and 1.409A-1(b)(9)(iii), (3) the Plan Payments constituting accelerated vesting satisfy, to the greatest extent possible, the
exemptions from the application of Section 409A provided under Treasury Regulation 1.409A-1(b)(5)(i)(A) and (ii), and (4) the Plan Payments constituting Continued Medical Benefits also satisfy, to the greatest extent possible, the
exemptions from the application of Section 409A provided under Treasury Regulation 1.409A-1(b)(9)(v). 
  

	8.	RIGHT TO INTERPRET PLAN; AMENDMENT AND TERMINATION.


 (a) Exclusive Discretion. The Plan Administrator shall have the exclusive discretion and authority to establish
rules, forms, and procedures for the administration of the Plan and to construe and interpret the Plan and to decide any and all questions of fact, interpretation, definition, computation or administration arising in connection with the operation of
the Plan, including, but not limited to, the eligibility to participate in the Plan and amount of benefits paid under the Plan. The rules, interpretations, computations, and other actions of the Plan Administrator shall be binding and conclusive on
all persons. 
 (b) Amendment or Termination. Nuvelo reserves the right to amend or terminate this Plan or the benefits provided
hereunder at any time; provided, however, that no such amendment or termination shall occur following a Change in Control or a Covered Termination as to any Participant who would be adversely affected by such amendment or termination unless
such Participant consents in writing to such amendment or termination. Any action amending or terminating the Plan shall be in writing and executed by a duly authorized officer of Nuvelo. Unless otherwise required by law, no approval of the
shareholders of Nuvelo shall be required for any amendment or termination including any amendment that increases the benefits provided under any Stock Award. 








	9.	TERMINATION OF CERTAIN EMPLOYEE BENEFITS. 

 Except as provided herein, all employee benefits other than health insurance and life insurance (such as disability and 401(k) plan coverage) terminate as
of a Participant’s employment termination date (except to the extent that a conversion privilege may be available thereunder). 
  

	10.	NO IMPLIED EMPLOYMENT CONTRACT. 

 The Plan shall not be deemed (i) to give any employee or other person any right to be retained in the employ of Nuvelo or (ii) to interfere with
the right of Nuvelo to discharge any employee or other person at any time, with or without cause, which right is hereby reserved. 
  

	11.	LEGAL CONSTRUCTION. 

 This Plan shall be governed by and construed under the laws of the State of California (without regard to principles of conflict of laws), except to the extent preempted by ERISA. 
  

	12.	CLAIMS, INQUIRIES AND APPEALS. 

 (a) Applications for Benefits and Inquiries. Any application for benefits, inquiries about the Plan or inquiries about present or future rights
under the Plan must be submitted to the Plan Administrator in writing. The Plan Administrator is:

submit) written comments, documents, records, and other information relating to his or her claim. The applicant (or his or her representative) shall be provided, upon request and free of charge, reasonable access to, and copies of, all documents,
records and other information relevant to his or her claim. The review shall take into account all comments, documents, records and other information submitted by the applicant (or his or her representative) relating to the claim, without regard to

(60) days after receipt of the request, unless special circumstances require an extension of time (not to exceed an additional sixty (60) days), for processing the request for a review. If an extension for review is required, written
notice of the extension will be furnished to the applicant within the initial sixty (60) day period. This notice of extension will describe the special circumstances necessitating the additional time and the date by which the Review Panel is to

 (1) the specific reason or reasons for the denial;

Administrator and/or the Review Panel may establish rules and procedures, consistent with the Plan and with ERISA, as necessary and appropriate in carrying out its responsibilities in reviewing benefit claims. If the applicant wishes to submit
additional information in connection with an appeal from the denial of benefits, he or she may be required to do so at his or her own expense.

	15.	STATEMENT OF ERISA RIGHTS. 

 Participants in this Plan (which is a welfare benefit plan sponsored by Nuvelo, Inc.) are entitled to certain rights and protections under ERISA. If you are an Eligible Employee, you are considered a participant in
the Plan for the purposes of this Section 15 and, under ERISA, you are entitled with respect to benefits covered by ERISA to: 
 Receive Information
About Your Plan And Benefits 
 (a) Examine, without charge, at the Plan Administrator’s office and at other specified
locations, such as worksites, all documents governing the Plan and a copy of the latest annual report (Form 5500 Series), if applicable, filed by the Plan with the U.S. Department of Labor and available at the Public Disclosure Room of the Pension
and Welfare Benefit Administration; 
 (b) Obtain, upon written request to the Plan Administrator, copies of documents governing the
operation of the Plan and copies of the latest annual report (Form 5500 Series), if applicable, and an updated (as necessary) Summary Plan Description. The Administrator may make a reasonable charge for the copies; and 
 (c) Receive a summary of the Plan’s annual financial report, if applicable. The Plan Administrator is required by law to furnish each
participant with a copy of this summary annual report, if applicable. 
 Prudent Actions By Plan Fiduciaries 
 In addition to creating rights for Plan participants, ERISA imposes duties upon the people who are responsible for the operation of the employee benefit
plan. The people who operate the Plan, called “fiduciaries” of the Plan, have a duty to do so prudently and in the interest of you and other Plan participants and beneficiaries. No one, including your employer, your union or any other
person, may fire you or otherwise discriminate against you in any way to prevent you from obtaining a Plan benefit or exercising your rights under ERISA. 







 Enforce Your Rights 
 If your claim for a Plan benefit is denied or ignored, in whole or in part, you have a right to know why this was done, to obtain copies of documents relating to the decision without charge, and to appeal any denial,
all within certain time schedules. 
 Under ERISA, there are steps you can take to
enforce the above rights. For instance, if you request a copy of Plan documents or the latest annual report from the Plan, if applicable,1 and do not
receive them within 30 days, you may file suit in a Federal court. In such a case, the court may require the Plan Administrator to provide the materials and pay you up to $110 a day until you receive the materials, unless the materials were not sent
because of reasons beyond the control of the Administrator. 
 If you have a claim for benefits which is denied or ignored, in whole
or in part, you may file suit in a state or Federal court. In addition, if you disagree with the Plan’s decision or lack thereof concerning the qualified status of a domestic relations order or a medical child support order, you may file suit
in a state or Federal court. 
 If you are discriminated against for asserting your rights, you may seek assistance from the U.S. Department
of Labor, or you may file suit in a Federal court. The court will decide who should pay court costs and legal fees. If you are successful, the court may order the person you have sued to pay these costs and fees. If you lose, the court may order you
to pay these costs and fees, for example, if it finds your claim is frivolous. 
 Assistance With Your Questions 
 If you have any questions about the Plan, you should contact the Plan Administrator. If you have any questions about this statement or about your rights
under ERISA, or if you need assistance in obtaining documents from the Plan Administrator, you should contact the nearest office of the Employee Benefits Security Administration, U.S. Department of Labor, listed in your telephone directory or the
Division of Technical Assistance and Inquiries, Employee Benefits Security Administration, U.S. Department of Labor, 200 Constitution Avenue N.W., Washington, D.C. 20210. You may also obtain certain publications about your rights and
responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration.
