Subsidiaries upon whose judgment, initiative and efforts the Company largely depends for the successful conduct of its business to acquire a proprietary interest in the Company. It is anticipated that

SECTION 2.    ADMINISTRATION OF PLAN; ADMINISTRATOR AUTHORITY TO SELECT GRANTEES AND DETERMINE
AWARDS


        (a)    Administration of Plan.    The Plan shall be administered by the Administrator. 


        (b)    Powers of Administrator.    The Administrator shall have the power and authority to grant Awards consistent
with the terms of the Plan, including the power and authority: 



        (i)    to
select the individuals to whom Awards may from time to time be granted; 


        (ii)   to
determine the time or times of grant, and the extent, if any, of Incentive Stock Options, Non-Qualified Stock Options, Stock Appreciation Rights,
Restricted Stock Awards, Deferred Stock Awards, Unrestricted Stock Awards, Cash-based Awards and Dividend Equivalent Rights, or any combination of the foregoing, granted to any one or more
grantees; 


        (iii)  to
determine the number of shares of Stock to be covered by any Award; 


        (iv)  to
determine and modify from time to time the terms and conditions, including restrictions, not inconsistent with the terms of the Plan, of any Award, which terms and
conditions may differ among individual Awards and grantees, and to approve the form of written instruments evidencing the Awards; 


        (v)   to
accelerate at any time the exercisability or vesting of all or any portion of any Award; 


        (vi)  subject
to the provisions of Section 5(a)(ii), to extend at any time the period in which Stock Options may be exercised; and 


        (vii) at
any time to adopt, alter and repeal such rules, guidelines and practices for administration of the Plan and for its own acts and proceedings as it shall deem
advisable; to interpret the terms and provisions of the Plan and any Award (including related written instruments); to make all determinations it deems advisable for the administration of the Plan; to
decide all disputes arising in connection with the Plan; and to otherwise supervise the administration of the Plan. 




        All
decisions and interpretations of the Administrator shall be binding on all persons, including the Company and Plan grantees. 


        (c)    Delegation of Authority to Grant Options.    Subject to applicable law, the Administrator, in its discretion,
may delegate to the Chief Executive Officer of the Company all or part of the Administrator's authority and duties with respect to the granting of Options, to individuals who are (i) not
subject to the reporting and other provisions of Section 16 of the Exchange Act and (ii) not Covered Employees. Any such delegation by the Administrator shall include a limitation as to
the amount of Options that may be granted during the period of the delegation and shall contain guidelines as to the determination of the exercise price and the vesting criteria. The Administrator may
revoke or amend the terms of a delegation at any time but such action shall not invalidate any prior actions of the Administrator's delegate or delegates that were consistent with the terms of the
Plan. 


        (d)    Award Agreement.    Awards under the Plan shall be evidenced by Award Agreements that set forth the terms,
conditions and limitations for each Award which may include, without limitation, the term of an Award, the provisions applicable in the event employment or service terminates, and the Company's
authority to unilaterally or bilaterally amend, modify, suspend, cancel or rescind an Award. 


        (e)    Indemnification.    Neither the Board nor the Administrator, nor any member of either or any delegate thereof,
shall be liable for any act, omission, interpretation, construction or determination made in good faith in connection with the Plan, and the members of the Board and the Administrator (and any
delegate thereof) shall be entitled in all cases to indemnification and reimbursement by the Company in respect of any claim, loss, damage or expense (including, without limitation, reasonable 


3







 



attorneys'
fees) arising or resulting therefrom to the fullest extent permitted by law and/or under the Company's articles or bylaws or any directors' and officers' liability insurance coverage which
may be in effect from time to time and/or any indemnification agreement between such individual and the Company. 



        (f)    Foreign Award Recipients.    Notwithstanding any provision of the Plan to the contrary, in order to comply with
the laws in other countries in which the Company and its Subsidiaries operate or have employees or other individuals eligible for Awards, the Administrator, in its sole discretion, shall have the
power and authority to: (i) determine which Subsidiaries shall be covered by the Plan; (ii) determine which individuals outside the United States are eligible to participate in the Plan;
(iii) modify the terms and conditions of any Award granted to individuals outside the United States to comply with applicable foreign laws; (iv) establish subplans and modify exercise
procedures and other terms and procedures, to the extent the Administrator determines such actions to be necessary or advisable (and such subplans and/or modifications shall be attached to this Plan
as appendices); provided, however, that no such subplans and/or modifications shall increase the share limitations contained in Section 3(a) hereof; and (v) take any action, before or
after an Award is made, that the Administrator determines to be necessary or advisable to obtain approval or comply with any local governmental regulatory exemptions or approvals. Notwithstanding the
foregoing, the Administrator may not take any actions hereunder, and no Awards shall be granted, that would violate the Exchange Act or any other applicable United States securities law, the Code, or
any other applicable United States governing statute or law. 


SECTION 3.    STOCK ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION 


        (a)    Stock Issuable.    The maximum number of shares of Stock reserved and available for issuance under the Plan
shall be the sum of (i) 6,481,198 shares, (ii) the number of Shares under the Company's 2003 Stock Option and Incentive Plan (the "2003 Plan") which are not needed to fulfill the
Company's obligations for awards issued under the 2003 Plan as a result of forfeiture, expiration, cancellation, termination or net issuances of awards thereunder, and (iii) on
January 1, 2008 and on each January 1 thereafter, an additional number of shares equal to the lower of (A) four and one-half percent (4.5%) of the outstanding number
of shares of Stock on the immediately preceding December 31, or (B) such lower number of shares of Stock as may be determined by the Board of Directors, in each case subject to
adjustment as provided in Section 3(b). For purposes of this limitation, the shares of Stock underlying any Awards that are forfeited, canceled, held back upon exercise of an Option or
settlement of an Award to cover the exercise price or tax withholding, reacquired by the Company prior to vesting, satisfied without the issuance of Stock or otherwise terminated (other than by
exercise) shall be added back to the shares of Stock available for issuance under the Plan. Subject to such overall limitations, shares of Stock may be issued up to such maximum number pursuant to any
type or types of Award; provided, however, that (i) Incentive Stock Options may be granted with respect to no more than 6,431,434 shares, plus on each January 1, starting
January 1, 2008, an additional number of shares equal to the lesser of (A) four and one-half percent (4.5%) of the outstanding number of shares of Stock on the immediately
preceding December 31 and (B) 3,150,000 shares of Stock and (ii) Stock Options or Stock Appreciation Rights with respect to no more than 6,500,000 shares of Stock may be granted
to any one individual grantee during any one calendar year period. The shares available for issuance under the Plan may be authorized but unissued shares of Stock or shares of Stock reacquired by the
Company. 


        (b)    Changes in Stock.    Subject to Section 3(c) hereof, if, as a result of any reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change in the Company's capital stock, the outstanding shares of Stock are increased or decreased
or are exchanged for a different number or kind of shares or other securities of the Company, or additional shares or new or different shares or other securities of the Company or other
non-cash assets are 


4







 

distributed
with respect to such shares of Stock or other securities, or, if, as a result of any merger or consolidation, sale of all or substantially all of the assets of the Company, the outstanding
shares of Stock are converted into or exchanged for securities of the Company or any successor entity (or a parent or subsidiary thereof), the Administrator shall make an appropriate or proportionate
adjustment in (i) the maximum number of shares reserved for issuance under the Plan, (ii) the number of Stock Options or Stock Appreciation Rights that can be granted to any one
individual grantee, (iii) the number and kind of shares or other securities subject to any then outstanding Awards under the Plan, (iv) the repurchase price, if any, per share subject to
each outstanding Restricted Stock Award, and (v) the price for each share subject to any then outstanding Stock Options and Stock Appreciation Rights under the Plan, without changing the
aggregate exercise price (i.e., the exercise price multiplied by the number of Stock Options and Stock Appreciation Rights) as to which such Stock Options and Stock Appreciation Rights remain
exercisable. The Administrator shall also make equitable or proportionate adjustments in the number of shares subject to outstanding Awards and the exercise price and the terms of outstanding Awards
to take into consideration cash dividends paid other than in the ordinary course or any other extraordinary corporate event. The adjustment by the Administrator shall be final, binding and conclusive.
No fractional shares of Stock shall be issued under the Plan resulting from any such adjustment, but the Administrator in its discretion may make a cash payment in lieu of fractional shares. 



        (c)    Mergers and Other Transactions.    Except as the Administrator may otherwise specify with respect to particular
Awards in the relevant Award documentation, in the case of and subject to the consummation of a Sale Event, the Administrator shall as to outstanding Awards (on the same basis or on different bases as
the Administrator shall specify), make appropriate provision for the assumption or continuation of Awards theretofore granted by the successor entity, or the substitution of such Awards with new
Awards of the successor entity or parent thereof, with appropriate adjustment as to the number and kind of shares and, if appropriate, the per share exercise prices, as the Administrator shall
specify. In addition to or in lieu of the foregoing, the Administrator may provide that, upon the effective time of the Sale Event, the Plan and all outstanding Awards granted hereunder shall
terminate. In the event of such termination, (i) the Company shall have the option (in its sole discretion) to make or provide for a cash payment to the grantees holding Options and Stock
Appreciation Rights, in exchange for the cancellation thereof, in an amount equal to the difference between (A) the Sale Price multiplied by the number of shares of Stock subject to outstanding
Options and Stock Appreciation Rights (to the extent then exercisable (after taking into account any acceleration hereunder) at prices not in excess of the Sale Price) and (B) the aggregate
exercise price of all such outstanding Options and Stock Appreciation Rights; or (ii) each grantee shall be permitted, within a specified period of time prior to the consummation of the Sale
Event as determined by the Administrator, to exercise all outstanding Options and Stock Appreciation Rights held by such grantee; provided, however, that, in the case of this clause (ii), all
Options and Stock Appreciation Rights that are not exercisable immediately prior to the effective time of the Sale Event shall become fully exercisable as of the effective time of the Sale Event. 


        (d)    Substitute Awards.    The Administrator may grant Awards under the Plan in substitution for stock and stock
based awards held by employees, directors or other key persons of another corporation in connection with the merger or consolidation of the employing corporation with the Company or a Subsidiary or
the acquisition by the Company or a Subsidiary of property or stock of the employing corporation. The Administrator may direct that the substitute awards be granted on such terms and conditions as the
Administrator considers appropriate in the circumstances. Any substitute Awards granted under the Plan shall not count against the share limitation set forth in Section 3(a). 


5







 

SECTION 4.    ELIGIBILITY 


        Grantees
under the Plan will be such full or part-time officers and other employees, Non-Employee Directors and key persons (including
consultants and prospective employees) of the Company and its Subsidiaries as are selected from time to time by the Administrator in its sole discretion. 


SECTION 5.    STOCK OPTIONS 


        Any
Stock Option granted under the Plan shall be in such form as the Administrator may from time to time approve. 



        Stock
Options granted under the Plan may be either Incentive Stock Options or Non-Qualified Stock Options. Incentive Stock Options may be granted only to employees of the
Company or any Subsidiary that is a "subsidiary corporation" within the meaning of Section 424(f) of the Code. To the extent that any Option does not qualify as an Incentive Stock Option, it
shall be deemed a Non-Qualified Stock Option. 


        (a)    Stock Options Granted to Employees and Key Persons.    The Administrator in its discretion may grant Stock
Options to eligible employees and key persons of the Company or any Subsidiary. Stock Options granted pursuant to this Section 5(a) shall be subject to the following terms and conditions and
shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the
Administrator shall deem desirable. If the Administrator so determines, Stock Options may be granted in lieu of cash compensation at the optionee's election, subject to such terms and conditions as
the Administrator may establish. 


                (i)    Exercise Price.    The exercise price per share for the Stock covered by a Stock Option granted
pursuant to this Section 5(a) shall be determined by the Administrator at the time of grant but shall not be less than 100 percent of the Fair Market Value on the date of grant. In the
case of an Incentive Stock Option that is granted to a Ten Percent Owner, the option price of such Incentive Stock Option shall be not less than 110 percent of the Fair Market Value on the
grant date. 


                (ii)    Option Term.    The term of each Stock Option shall be fixed by the Administrator, but no Stock
Option shall be exercisable more than ten years after the date the Stock Option is granted. In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the term of such Stock
Option shall be no more than five years from the date of grant. 


                (iii)    Exercisability; Rights of a Stockholder.    Stock Options shall become exercisable at such time
or times, whether or not in installments, as shall be determined by the Administrator at or after the grant date. The Administrator may at any time accelerate the exercisability of all or any portion
of any Stock Option. An optionee shall have the rights of a stockholder only as to shares acquired upon the exercise of a Stock Option and not as to unexercised Stock Options. 



                (iv)    Method of Exercise.    Stock Options may be exercised in whole or in part, by giving written
notice of exercise to the Company, specifying the number of shares to be purchased. Payment of the purchase price may be made by one or more of the following methods to the extent provided in the
Option Award Agreement: 



        (A)  In
cash, by certified or bank check or other instrument acceptable to the Administrator; 


        (B)  Through
the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the optionee on the open market or that are beneficially owned by
the optionee and are not then subject to restrictions under any Company plan. Such surrendered shares shall be valued at Fair Market Value on the exercise date. To the extent required to avoid
variable accounting treatment under FAS 123R or other applicable accounting rules, such surrendered shares shall have been owned by the optionee for at least six months; or 



6







 

        (C)  By
the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash
or a check payable and acceptable to the Company for the purchase price; provided that in the event the optionee chooses to pay the purchase price as so provided, the optionee and the broker shall
comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as a condition of such payment procedure. 




Payment
instruments will be received subject to collection. The transfer to the optionee on the records of the Company or of the transfer agent of the shares of Stock to be purchased pursuant to the
exercise of a Stock Option will be contingent upon receipt from the optionee (or a purchaser acting in his stead in accordance with the provisions of the Stock Option) by the Company of the full
purchase price for such shares and the fulfillment of any other requirements contained in the Option Award Agreement or applicable provisions of laws (including the satisfaction of any withholding
taxes that the Company is obligated to withhold with respect to the optionee). In the event an optionee chooses to pay the purchase price by previously-owned shares of Stock through the attestation
method, the number of shares of Stock transferred to the optionee upon the exercise of the Stock Option shall be net of the number of shares attested to. In the event that the Company establishes, for
itself or using the services of a third party, an automated system for the exercise of Stock Options, such as a system using an internet website or interactive voice response, then the paperless
exercise of Stock Options may be permitted through the use of such an automated system. 



        (v)    Annual Limit on Incentive Stock Options.    To the extent required for "incentive stock option" treatment under
Section 422 of the Code, the aggregate Fair Market Value (determined as of the time of grant) of the shares of Stock with respect to which Incentive Stock Options granted under this Plan and
any other plan of the Company or its parent and subsidiary corporations become exercisable for the first time by an optionee during any calendar year shall not exceed $100,000. To the extent that any
Stock Option exceeds this limit, it shall constitute a Non-Qualified Stock Option. 



        (b)    Stock Options Granted to Non-Employee Directors.    The Administrator in its discretion may grant
Non-Qualified Stock Options to Non-Employee Directors. Non-Qualified Stock Options granted pursuant to this Section 5(b) shall be subject to the following
terms and conditions and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable. If the Administrator so determines,
Non-Qualified Stock Options may be granted in lieu of cash compensation at the optionee's election, subject to such terms and conditions as the Administrator may establish. 



                (i)    Exercise Price.    The exercise price per share for the Stock covered by a Stock Option granted
pursuant to this Section 5(b) shall be no less than 100 percent of the Fair Market Value of the Stock on the date the Stock Option is granted. 


                (ii)    Exercise; Termination.    



        (A)  Options
shall become exercisable at such time or times, whether or not in installments, as shall be determined by the Administrator at or after the grant date. The
Administrator may at any time accelerate the exercisability of all or any portion of any Stock Option. A Stock Option issued under this Section 5(b) shall not be exercisable after the
expiration of ten years from the date of grant. 


        (B)  Stock
Options granted under this Section 5(b) may be exercised only by written notice to the Company specifying the number of shares to be purchased. Payment of
the full purchase price of the shares to be purchased may be made by one or more of the methods specified in Section 5(a)(iv). An optionee shall have the rights of a stockholder only as to
shares acquired upon the exercise of a Stock Option and not as to unexercised Stock Options. 



7







 

SECTION 6.    STOCK APPRECIATION RIGHTS 


        (a)    Exercise Price of Stock Appreciation Rights.    The exercise price of a Stock Appreciation Right shall not be
less than 100 percent of the Fair Market Value of the Stock on the date of grant (or more than the Stock Option exercise price per share, if the Stock Appreciation Right was granted in tandem
with a Stock Option). 


        (b)    Grant and Exercise of Stock Appreciation Rights.    Stock Appreciation Rights may be granted by the
Administrator in tandem with, or independently of, any Stock Option granted pursuant to Section 5 of the Plan. In the case of a Stock Appreciation Right granted in tandem with a
Non-Qualified Stock Option, such Stock Appreciation Right may be granted either at or after the time of the grant of such Option. In the case of a Stock Appreciation Right granted in
tandem with an Incentive Stock Option, such Stock Appreciation Right may be granted only at the time of the grant of the Option. 


        A
Stock Appreciation Right or applicable portion thereof granted in tandem with a Stock Option shall terminate and no longer be exercisable upon the termination or exercise of the
related Option. 


        (c)    Terms and Conditions of Stock Appreciation Rights.    Stock Appreciation Rights shall be subject to such terms
and conditions as shall be determined from time to time by the Administrator, subject to the following: 



        (i)    Stock
Appreciation Rights granted in tandem with Options shall be exercisable at such time or times and to the extent that the related Stock Options shall be
exercisable. 


        (ii)   Upon
exercise of a Stock Appreciation Right, the applicable portion of any related Option shall be surrendered. 


        (iii)  Stock
Appreciation Rights may have a term of no more than ten years. 




SECTION 7.    RESTRICTED STOCK AWARDS 



        (a)    Nature of Restricted Stock Awards.    The Administrator shall determine the restrictions and conditions
applicable to each Restricted Stock Award at the time of grant. Conditions may be based on continuing employment (or other service relationship) and/or achievement of pre-established
performance goals and objectives. The grant of a Restricted Stock Award is contingent on the grantee executing the Restricted Stock Award Agreement. The terms and conditions of each such Award
Agreement shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees. 



        (b)    Rights as a Stockholder.    Upon execution of the Restricted Stock Award Agreement and payment of any
applicable purchase price, a grantee shall have the rights of a stockholder with respect to the voting of the Restricted Stock, subject to such conditions contained in the Restricted Stock Award
Agreement. Unless the Administrator shall otherwise determine, (i) uncertificated Restricted Stock shall be accompanied by a notation on the records of the Company or the transfer agent to the
effect that they are subject to forfeiture until such Restricted Stock are vested as provided in Section 7(d) below, and (ii) certificated Restricted Stock shall remain in the possession
of the Company until such Restricted Stock is vested as provided in Section 7(d) below, and the grantee shall be required, as a condition of the grant, to deliver to the Company such
instruments of transfer as the Administrator may prescribe. 


        (c)    Restrictions.    Restricted Stock may not be sold, assigned, transferred, pledged or otherwise encumbered or
disposed of except as specifically provided herein or in the Restricted Stock Award Agreement. Except as may otherwise be provided by the Administrator either in the Award Agreement or, subject to
Section 16 below, in writing after the Award Agreement is issued, if any, if a grantee's 


8







 



employment
(or other service relationship) with the Company and its Subsidiaries terminates for any reason, any Restricted Stock that has not vested at the time of termination shall automatically and
without any requirement of notice to such grantee from or other action by or on behalf of, the Company be deemed to have been reacquired by the Company at its original purchase price (if any) from
such grantee or such grantee's legal representative simultaneously with such termination of employment (or other service relationship), and thereafter shall cease to represent any ownership of the
Company by the grantee or rights of the grantee as a stockholder. Following such deemed reacquisition of unvested Restricted Stock that are represented by physical certificates, a grantee shall
surrender such certificates to the Company upon request without consideration. 


        (d)    Vesting of Restricted Stock.    The Administrator at the time of grant shall specify the date or dates and/or
the attainment of pre-established performance goals, objectives and other conditions on which the non-transferability of the Restricted Stock and the Company's right of
repurchase or forfeiture shall lapse. Subsequent to such date or dates and/or the attainment of such pre-established performance goals, objectives and other conditions, the shares on which
all restrictions have lapsed shall no longer be Restricted Stock and shall be deemed "vested." Except as may otherwise be provided by the Administrator either in the Award Agreement or, subject to
Section 16 below, in writing after the Award Agreement is issued, a grantee's rights in any shares of Restricted Stock that have not vested shall automatically terminate upon the grantee's
termination of employment (or other service relationship) with the Company and its Subsidiaries and such shares shall be subject to the provisions of Section 7(c) above. 


SECTION 8.    DEFERRED STOCK AWARDS 



        (a)    Nature of Deferred Stock Awards.    The Administrator shall determine the restrictions and conditions
applicable to each Deferred Stock Award at the time of grant. Conditions may be based on continuing employment (or other service relationship) and/or achievement of pre-established
performance goals and objectives. The grant of a Deferred Stock Award is contingent on the grantee executing the Deferred Stock Award Agreement. The terms and conditions of each such Award Agreement
shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees. At the end of the deferral period, the Deferred Stock Award, to the extent
vested, shall be settled in the form of shares of Stock. 


        (b)    Election to Receive Deferred Stock Awards in Lieu of Compensation.    The Administrator may, in its sole
discretion, permit a grantee to elect to receive a portion of future cash compensation otherwise due to such grantee in the form of a Deferred Stock Award. Any such election shall be made in writing
and shall be delivered to the Company no later than the date specified by the Administrator and in accordance with Section 409A and such other rules and procedures established by the
Administrator. Any such future cash compensation that the grantee elects to defer shall be converted to a fixed number of phantom stock units based on the Fair Market Value of Stock on the date the
compensation would otherwise have been paid to the grantee if such payment had not been deferred as provided herein. The Administrator shall have the sole right to determine whether and under what
circumstances to permit such elections and to impose such limitations and other terms and conditions thereon as the Administrator deems appropriate. 


        (c)    Rights as a Stockholder.    A grantee shall have the rights as a stockholder only as to shares of Stock
acquired by the grantee upon settlement of a Deferred Stock Award; provided, however, that the grantee may be credited with Dividend Equivalent Rights with respect to the phantom stock units
underlying his Deferred Stock Award, subject to such terms and conditions as the Administrator may determine. 



        (d)    Termination.    Except as may otherwise be provided by the Administrator either in the Award Agreement or,
subject to Section 16 below, in writing after the Award Agreement is issued, a grantee's 


9







 



right
in all Deferred Stock Awards that have not vested shall automatically terminate upon the grantee's termination of employment (or cessation of service relationship) with the Company and its
Subsidiaries for any reason. 


SECTION 9.    UNRESTRICTED STOCK AWARDS 


         
Grant or Sale of Unrestricted Stock.    The Administrator may, in its sole discretion, grant (or sell at par value or such higher purchase price determined by the
Administrator) an Unrestricted Stock Award under the Plan. Unrestricted Stock Awards may be granted in respect of past services or other valid consideration, or in lieu of cash compensation due to
such grantee. 


SECTION 10.    CASH-BASED AWARDS 


         
Grant of Cash-based Awards.    The Administrator may, in its sole discretion, grant Cash-based Awards to any grantee in such number or amount
and upon such terms, and subject to such conditions, as the Administrator shall determine at the time of grant. The Administrator shall determine the maximum duration of the Cash-based
Award, the amount of cash to which the Cash-based Award pertains, the conditions upon which the Cash-based Award shall become vested or payable, and such other provisions as
the Administrator shall determine. Each Cash-based Award shall specify a cash-denominated payment amount, formula or payment ranges as determined by the Administrator. Payment,
if any, with respect to a Cash-based Award shall be made in accordance with the terms of the Award and may be made in cash or in shares of Stock, as the Administrator determines. 


SECTION 11.    DIVIDEND EQUIVALENT RIGHTS 



        (a)    Dividend Equivalent Rights.    A Dividend Equivalent Right may be granted hereunder to any grantee as a
component of another Award or as a freestanding award. The terms and conditions of Dividend Equivalent Rights shall be specified in the Award Agreement. Dividend equivalents credited to the holder of
a Dividend Equivalent Right may be paid currently or may be deemed to be reinvested in additional shares of Stock, which may thereafter accrue additional equivalents. Any such reinvestment shall be at
Fair Market Value on the date of reinvestment or such other price as may then apply under a dividend reinvestment plan sponsored by the Company, if any. Dividend Equivalent Rights may be settled in
cash or shares of Stock or a combination thereof, in a single installment or installments. A Dividend Equivalent Right granted as a component of another Award may provide that such Dividend Equivalent
Right shall be settled upon exercise, settlement, or payment of, or lapse of restrictions on, such other Award, and that such Dividend Equivalent Right shall expire or be forfeited or annulled under
the same conditions as such other Award. A Dividend Equivalent Right granted as a component of another Award may also contain terms and conditions different from such other Award. 


        (b)    Interest Equivalents.    Any Award under this Plan that is settled in whole or in part in cash on a deferred
basis may provide in the grant for interest equivalents to be credited with respect to such cash
payment. Interest equivalents may be compounded and shall be paid upon such terms and conditions as may be specified by the grant. 


        (c)    Termination.    Except as may otherwise be provided by the Administrator either in the Award Agreement or,
subject to Section 16 below, in writing after the Award Agreement is issued, a grantee's rights in all Dividend Equivalent Rights or interest equivalents granted as a component of another Award
that has not vested shall automatically terminate upon the grantee's termination of employment (or cessation of service relationship) with the Company and its Subsidiaries for any reason. 


10







 

SECTION 12.    TRANSFERABILITY OF AWARDS 


        (a)    Transferability.    Except as provided in Section 12(b) below, during a grantee's lifetime, his or her
Awards shall be exercisable only by the grantee, or by the grantee's legal representative or guardian in the event of the grantee's incapacity. No Awards shall be sold, assigned, transferred or
otherwise encumbered or disposed of by a grantee other than by will or by the laws of descent and distribution. No Awards shall be subject, in whole or in part, to attachment, execution, or levy of
any kind, and any purported transfer in violation hereof shall be null and void. 


        (b)    Administrator Action.    Notwithstanding Section 12(a), the Administrator, in its discretion, may
provide either in the Award Agreement regarding a given Award or by subsequent written approval that the grantee (who is an employee or director) may transfer his or her Awards (other than any
Incentive Stock Options) to his or her immediate family members, to trusts for the benefit of such family members, or to partnerships in which such family members are the only partners, provided that
the transferee agrees in writing with the Company to be bound by all of the terms and conditions of this Plan and the applicable Award. 


        (c)    Family Member.    For purposes of Section 12(b), "family member" shall mean a grantee's child,
stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law,
son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including
adoptive relationships, any person sharing the grantee's household (other than a tenant of the grantee), a trust in which these persons (or the grantee) have more than 50 percent of the
beneficial interest, a foundation in which these persons (or the grantee) control the management of assets, and any other entity in which these persons (or the grantee) own more than 50 percent
of the voting interests. 


        (d)    Designation of Beneficiary.    Each grantee to whom an Award has been made under the Plan may designate a
beneficiary or beneficiaries to exercise any Award or receive any payment under any Award payable on or after the grantee's death. Any such designation shall be on a form provided for that purpose by
the Administrator and shall not be effective until received by the Administrator. If no beneficiary has been designated by a deceased grantee, or if the designated beneficiaries have predeceased the
grantee, the beneficiary shall be the grantee's estate. 


SECTION 13.    TAX WITHHOLDING 


        (a)    Payment by Grantee.    Each grantee shall, no later than the date as of which the value of an Award or of any
Stock or other amounts received thereunder first becomes includable in the gross income of the grantee for Federal income tax purposes, pay to the Company, or make arrangements satisfactory to the
Administrator regarding payment of, any Federal, state, or local taxes of any kind required by law to be withheld by the Company with respect to such income. The Company and its Subsidiaries shall, to
the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the grantee. The Company's obligation to deliver evidence of book entry (or stock
certificates) to any grantee is subject to and conditioned on tax withholding obligations being satisfied by the grantee. 


        (b)    Payment in Stock.    Subject to approval by the Administrator, a grantee may elect to have the Company's
minimum required tax withholding obligation satisfied, in whole or in part, by authorizing the Company to withhold from shares of Stock to be issued pursuant to any Award a number of shares with an
aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the withholding amount due. 


11







 

SECTION 14.    ADDITIONAL CONDITIONS APPLICABLE TO NONQUALIFIED DEFERRED COMPENSATION UNDER SECTION 409A. 



        In
the event any Stock Option or Stock Appreciation Right under the Plan is materially modified and deemed a new grant at a time when the Fair Market Value
exceeds the exercise price, or any other Award is otherwise determined to constitute "nonqualified deferred compensation" within the meaning of Section 409A (a "409A Award"), the following
additional conditions shall apply and shall supersede any contrary provisions of this Plan or the terms of any agreement relating to such 409A Award. 


        (a)    Exercise and Distribution.    Except as provided in Section 14(b) hereof, no 409A Award shall be
exercisable or distributable earlier than upon one of the following: 



        (i)    Specified Time.    A specified time or a fixed schedule set forth in the written instrument evidencing the 409A
Award. 


        (ii)    Separation from Service.    Separation from service (within the meaning of Section 409A) by the 409A
Award grantee; provided, however, that if the 409A Award grantee is a "key employee" (as defined in Section 416(i) of the Code without regard to paragraph (5) thereof) and any of
the Company's Stock is publicly traded on an established securities market or otherwise, exercise or distribution under this Section 14(a)(ii) may not be made before the date that is six
months after the date of separation from service. 


        (iii)    Death.    The date of death of the 409A Award grantee. 


        (iv)    Disability.    The date the 409A Award grantee becomes disabled (within the meaning of
Section 14(c)(ii) hereof). 


        (v)    Unforeseeable Emergency.    The occurrence of an unforeseeable emergency (within the meaning of
Section 14(c)(iii) hereof), but only if the net value (after payment of the exercise price) of the number of shares of Stock that become issuable does not exceed the amounts necessary to
satisfy such emergency plus amounts necessary to pay taxes reasonably anticipated as a result of the exercise, after taking into account the extent to which the emergency is or may be relieved through
reimbursement or compensation by insurance or otherwise or by liquidation of the grantee's other assets (to the extent such liquidation would not itself cause severe financial hardship). 



        (vi)    Change in Control Event.    The occurrence of a Change in Control Event (within the meaning of
Section 14(c)(i) hereof), including the Company's discretionary exercise of the right to accelerate vesting of such grant upon a Change in Control Event or to terminate the Plan or any
409A Award granted hereunder within 12 months of the Change in Control Event. 




        (b)    No Acceleration.    A 409A Award may not be accelerated or exercised prior to the time specified in
Section 14(a) hereof, except in the case of one of the following events: 



        (i)    Domestic Relations Order.    The 409A Award may permit the acceleration of the exercise or distribution time or
schedule to an individual other than the grantee as may be necessary to comply with the terms of a domestic relations order (as defined in Section 414(p)(1)(B) of the Code). 


        (ii)    Conflicts of Interest.    The 409A Award may permit the acceleration of the exercise or distribution time or
schedule as may be necessary to comply with the terms of a certificate of divestiture (as defined in Section 1043(b)(2) of the Code). 



        (iii)    Change in Control Event.    The Administrator may exercise the discretionary right to accelerate the vesting
of such 409A Award upon a Change in Control Event or to terminate the Plan or any 409A Award granted thereunder within 12 months of the Change in Control Event and cancel the 409A Award for
compensation. 



12







 

        (c)    Definitions.    Solely for purposes of this Section 14 and not for other purposes of the Plan, the
following terms shall be defined as set forth below: 



        (i)    "Change
in Control Event" means the occurrence of a change in the ownership of the Company, a change in effective control of the Company, or a change in the ownership of
a substantial portion of the assets of the Company (as defined in Section 1.409A-3(g) of the proposed regulations promulgated under Section 409A by the Department of the
Treasury on September 29, 2005 or any subsequent guidance). 



        (ii)    "Disabled"
means a grantee who (i) is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment
that can be expected to result in death or can be expected to last for a continuous period of not less than 12 months, or (ii) is, by reason of any
medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than 12 months, receiving income
replacement benefits for a period of not less than three months under an accident and health plan covering employees of the Company or its Subsidiaries. 



        (iii)    "Unforeseeable
Emergency" means a severe financial hardship to the grantee resulting from an illness or accident of the grantee, the grantee's spouse, or a dependent
(as defined in Section 152(a) of the Code) of the grantee, loss of the grantee's property due to casualty, or similar extraordinary and unforeseeable circumstances arising as a result of events
beyond the control of the grantee. 




SECTION 15.    TRANSFER, LEAVE OF ABSENCE, ETC. 


        For
purposes of the Plan, the following events shall not be deemed a termination of employment: 



        (a)   a
transfer to the employment of the Company from a Subsidiary or from the Company to a Subsidiary, or from one Subsidiary to another; or 


        (b)   an
approved leave of absence for military service or sickness, or for any other purpose approved by the Company, if the employee's right to re-employment is
guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was granted or if the Administrator otherwise so provides in writing. 




SECTION 16.    AMENDMENTS AND TERMINATION 


        The
Board may, at any time, amend or discontinue the Plan and the Administrator may, at any time, amend or cancel any outstanding Award for the purpose of
satisfying changes in law or for any other lawful purpose, but no such action shall adversely affect rights under any outstanding Award without the holder's consent. Except as provided in
Section 3(b) or 3(c), in no event may the Administrator exercise its discretion to reduce the exercise price of outstanding Stock Options or Stock Appreciation Rights or effect repricing
through cancellation and re-grants. Any material Plan amendments (other than amendments that curtail the scope of the Plan), including any Plan amendments that (i) increase the
number of shares reserved for issuance under the Plan, (ii) expand the type of Awards available under, materially expand the eligibility to participate in, or materially extend the term of, the
Plan, or (iii) materially change the method of determining Fair Market Value, shall be subject to approval by the Company stockholders entitled to
vote at a meeting of stockholders. In addition, to the extent determined by the Administrator to be required by the Code to ensure that Incentive Stock Options granted under the Plan are qualified
under Section 422 of the Code or to ensure that compensation earned under Awards qualifies as performance-based compensation under Section 162(m) of the Code, Plan amendments shall be
subject to approval by the Company stockholders entitled to vote at a meeting of stockholders. Nothing in this Section 16 shall limit the Administrator's authority to take any action permitted
pursuant to Section 3(c). 


13







 

SECTION 17.    STATUS OF PLAN 


        With
respect to the portion of any Award that has not been exercised and any payments in cash, Stock or other consideration not received by a grantee, a
grantee shall have no rights greater than those of a general creditor of the Company unless the Administrator shall otherwise expressly determine in connection with any Award or Awards. In its sole
discretion, the Administrator may authorize the creation of trusts or other arrangements to meet the Company's obligations to deliver Stock or make payments with respect to Awards hereunder, provided
that the existence of such trusts or other arrangements is consistent with the foregoing sentence. 


SECTION 18.    GENERAL PROVISIONS 



        (a)    No Distribution.    The Administrator may require each person acquiring Stock pursuant to an Award to represent
to and agree with the Company in writing that such person is acquiring the shares without a view to distribution thereof. 


        (b)    Delivery of Stock Certificates.    Stock certificates to grantees under this Plan shall be deemed delivered for
all purposes when the Company or a stock transfer agent of the Company shall have mailed such certificates in the United States mail, addressed to the grantee, at the grantee's last known address on
file with the Company. Uncertificated Stock shall be deemed delivered for all purposes when the Company or a Stock transfer agent of the Company shall have given to the grantee by electronic mail
(with proof of receipt) or by United States mail, addressed to the grantee, at the grantee's last known
address on file with the Company, notice of issuance and recorded the issuance in its records (which may include electronic "book entry" records). Notwithstanding anything herein to the contrary, the
Company shall not be required to issue or deliver any certificates evidencing shares of Stock pursuant to the exercise of any Award, unless and until the Board has determined, with advice of counsel
(to the extent the Board deems such advice necessary or advisable), that the issuance and delivery of such certificates is in compliance with all applicable laws, regulations of governmental
authorities and, if applicable, the requirements of any exchange on which the shares of Stock are listed, quoted or traded. All Stock certificates delivered pursuant to the Plan shall be subject to
any stop-transfer orders and other restrictions as the Administrator deems necessary or advisable to comply with federal, state or foreign jurisdiction, securities or other laws, rules and
quotation system on which the Stock is listed, quoted or traded. The Administrator may place legends on any Stock certificate to reference restrictions applicable to the Stock. In addition to the
terms and conditions provided herein, the Board may require that an individual make such reasonable covenants, agreements, and representations as the Board, in its discretion, deems necessary or
advisable in order to comply with any such laws, regulations, or requirements. The Administrator shall have the right to require any individual to comply with any timing or other restrictions with
respect to the settlement or exercise of any Award, including a window-period limitation, as may be imposed in the discretion of the Administrator. 


        (c)    Stockholder Rights.    Until Stock is deemed delivered in accordance with Section 18(b), no right to
vote or receive dividends or any other rights of a stockholder will exist with respect to shares of Stock to be issued in connection with an Award, notwithstanding the exercise of a Stock Option or
any other action by the grantee with respect to an Award. 


        (d)    Other Compensation Arrangements; No Employment Rights.    Nothing contained in this Plan shall prevent the
Board from adopting other or additional compensation arrangements, including trusts, and such arrangements may be either generally applicable or applicable only in specific cases. The adoption of this
Plan and the grant of Awards do not confer upon any employee any right to continued employment with the Company or any Subsidiary. 


14







 

        (e)    Trading Policy Restrictions.    Option exercises and other Awards under the Plan shall be subject to such
Company's insider trading policy and procedures, as in effect from time to time. 


        (f)    Forfeiture of Awards under Sarbanes-Oxley Act.    If the Company is required to prepare an accounting
restatement due to the material noncompliance of the Company, as a result of misconduct, with any financial reporting requirement under the securities laws, then any grantee who is one of the
individuals subject to automatic forfeiture under Section 304 of the Sarbanes-Oxley Act of 2002 shall reimburse the Company for the amount of any Award received by such individual under the
Plan during the 12-month period following the first public issuance or filing with the United
States Securities and Exchange Commission, as the case may be, of the financial document embodying such financial reporting requirement. 


SECTION 19.    EFFECTIVE DATE OF PLAN 


        This
Plan shall become effective upon approval by the holders of a majority of the votes cast at a meeting of stockholders at which a quorum is present or
pursuant to written consent. No grants of Stock Options and other Awards may be made hereunder after the tenth anniversary of the Effective Date and no grants of Incentive Stock Options may be made
hereunder after the tenth anniversary of the date the Plan is approved by the Board. 


SECTION 20.    GOVERNING LAW 


        This
Plan and all Awards and actions taken thereunder shall be governed by, and construed in accordance with, the laws of Delaware, applied without regard to
conflict of law principles.

hereby grants to the Optionee named above an option (the "Stock Option") to purchase on or prior to the Expiration Date specified above all or part of the number of shares of Common Stock, par value
$0.001 per share (the "Stock"), of the Company specified above at the Option Exercise Price per Share specified above subject to the terms and conditions set forth herein and in the Plan. 



        1.    Exercisability Schedule.    No portion of this Stock Option may be exercised until such portion shall have
become exercisable. Except as set forth below, and subject to the discretion of the Administrator (as defined in Section 2 of the Plan) to accelerate the exercisability schedule hereunder, this
Stock Option shall be exercisable with respect to the following number of Option Shares on the dates indicated: 



			
	Incremental Number of

Option Shares Exercisable 	 	Exercisability Date 
	25% of Shares	 	One year from Vesting Start Date

 [Note that for ISOs, Option Shares for no more than

$100,000 may become exercisable per year.]  


        Once
exercisable, this Stock Option shall continue to be exercisable at any time or times prior to the close of business on the Expiration Date, subject to the provisions hereof and of
the Plan. 


        2.    Manner of Exercise.    



        (a)    The
Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the Expiration Date of this Stock Option, the Optionee may
give written notice to the Administrator of his or her election to purchase some or all of the Option Shares purchasable at the time of such notice. This notice shall specify the number of Option
Shares to be purchased. 


        Payment
of the purchase price for the Option Shares may be made by one or more of the following methods: (i) in cash, by certified or bank check or other instrument acceptable to
the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the Optionee on the open market or that are beneficially owned by
the Optionee and are not then subject to any restrictions under any Company plan and that otherwise satisfy any holding periods as may be required by the Administrator; (iii) by the Optionee
delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the
Company to pay the option purchase price, provided that in the event the Optionee chooses to pay the option purchase price as so provided, the Optionee and the broker shall comply with such procedures
and enter into 







 



such
agreements of indemnity and other agreements as the Administrator shall prescribe as a condition of such payment procedure; or (iv) a combination of (i), (ii) and
(iii) above. Payment instruments will be received subject to collection. 


        The
transfer to the Optionee on the records of the Company or of the transfer agent of the Option Shares will be contingent upon (i) the Company's receipt from the Optionee of the
full purchase price for the Option Shares, as set forth above, (ii) the fulfillment of any other requirements contained herein or in the Plan or in any other agreement or provision of laws, and
(iii) the receipt by the Company of any agreement, statement or other evidence that the Company may require to satisfy itself that the issuance of Stock to be purchased pursuant to the exercise
of Stock Options under the Plan and any subsequent resale of the shares of Stock will be in compliance with applicable laws and regulations. In the event the Optionee chooses to pay the purchase price
by previously-owned shares of Stock through the attestation method, the number of shares of Stock transferred to the Optionee upon the exercise of the Stock Option shall be net of the shares attested
to. 


        (b)    The
shares of Stock purchased upon exercise of this Stock Option shall be transferred to the Optionee on the records of the Company or of the transfer agent upon
compliance to the satisfaction of the Administrator with all requirements under applicable laws or regulations in connection with such issuance and with the requirements hereof and of the Plan. The
determination of the Administrator as to such compliance shall be final and binding on the Optionee. The Optionee shall not be deemed to be the holder of, or to have any of the rights of a holder with
respect to, any shares of Stock subject to this Stock Option unless and until this Stock Option shall have been exercised pursuant to the terms hereof, the Company or the transfer agent shall have
transferred the shares to the Optionee, and the Optionee's name shall have been entered as the stockholder of record on the books of the Company. Thereupon, the Optionee shall have full voting,
dividend and other ownership rights with respect to such shares of Stock. 


        (c)    The
minimum number of shares with respect to which this Stock Option may be exercised at any one time shall be 100 shares, unless the number of shares with respect to
which this Stock Option is being exercised is the total number of shares subject to exercise under this Stock Option at the time. 


        (d)    Notwithstanding
any other provision hereof or of the Plan, no portion of this Stock Option shall be exercisable after the Expiration Date hereof. 


        3.    Termination of Employment.    If the Optionee's employment by the Company or a Subsidiary (as defined in the
Plan) is terminated, the period within which to exercise the Stock Option may be subject to earlier termination as set forth below. 



        (a)    Termination Due to Death.    If the Optionee's employment terminates by reason of the Optionee's death, any
portion of this Stock Option outstanding on such date shall become fully exercisable and may thereafter be exercised by the Optionee's legal representative or legatee for a period of 12 months
from the date of death or until the Expiration Date, if earlier. 


        (b)    Termination Due to Disability.    If the Optionee's employment terminates by reason of the Optionee's
disability (as determined by the Administrator), any portion of this Stock Option outstanding on such
date shall become fully exercisable and may thereafter be exercised by the Optionee for a period of 12 months from the date of termination or until the Expiration Date, if earlier. 


        (c)    Termination for Cause.    If the Optionee's employment terminates for Cause, any portion of this Stock Option
outstanding on such date shall terminate immediately and be of no further force and effect. For purposes hereof, "Cause" shall mean, unless otherwise provided in an employment agreement between the
Company and the Optionee, a determination by the Administrator that the Optionee shall be dismissed as a result of (i) any material breach by the Optionee of any agreement between the Optionee
and the Company; (ii) the conviction of, indictment for or plea of nolo

contendere
by the Optionee to a felony or a crime involving moral turpitude; or (iii) any material misconduct or willful and deliberate non-performance (other than by reason of
disability) by the Optionee of the Optionee's duties to the Company. 



        (d)    Other Termination.    If the Optionee's employment terminates for any reason other than the Optionee's death,
the Optionee's disability, or Cause, and unless otherwise determined by the Administrator, any portion of this Stock Option outstanding on such date may be exercised, to the extent exercisable on the
date of termination, for a period of three months from the date of termination or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of
termination shall terminate immediately and be of no further force or effect. 



        The
Administrator's determination of the reason for termination of the Optionee's employment shall be conclusive and binding on the Optionee and his or her representatives or legatees. 


        4.    Incorporation of Plan.    Notwithstanding anything herein to the contrary, this Stock Option shall be subject to
and governed by all the terms and conditions of the Plan, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized terms in this Agreement shall have the
meaning specified in the Plan, unless a different meaning is specified herein. 



        5.    Transferability.    This Agreement is personal to the Optionee, is non-assignable and is not
transferable in any manner, by operation of law or otherwise, other than by will or the laws of descent and distribution. This Stock Option is exercisable, during the Optionee's lifetime, only by the
Optionee, and thereafter, only by the Optionee's legal representative or legatee. 


        6.    Status of the Stock Option.    This Stock Option is intended to qualify as an "incentive stock option" under
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"), but the Company does not represent or warrant that this Stock Option qualifies as such. The Optionee should consult
with his or her own tax advisors regarding the tax effects of this Stock Option and the requirements
necessary to obtain favorable income tax treatment under Section 422 of the Code, including, but not limited to, holding period requirements. To the extent any portion of this Stock Option does
not so qualify as an "incentive stock option," such portion shall be deemed to be a non-qualified stock option. If the Optionee intends to dispose or does dispose (whether by sale, gift,
transfer or otherwise) of any Option Shares within the one-year period beginning on the date after the transfer of such shares to him or her, or within the two-year period
beginning on the day after the grant of this Stock Option, he or she will so notify the Company within 30 days after such disposition. 


        7.    Tax Withholding.    The Optionee shall, not later than the date as of which the exercise of this Stock Option
becomes a taxable event for Federal income tax purposes, pay to the Company or make arrangements satisfactory to the Administrator for payment of any Federal, state, and local taxes required by law to
be withheld on account of such taxable event. The Optionee may elect to have the minimum required tax withholding obligation satisfied, in whole or in part, by authorizing the Company to withhold from
shares of Stock to be issued a number of shares of Stock with an aggregate Fair Market Value that would satisfy the withholding amount due. 



        8.    No Obligation to Continue Employment.    Neither the Company nor any Subsidiary is obligated by or as a result
of the Plan or this Agreement to continue the Optionee in employment and neither the Plan nor this Agreement shall interfere in any way with the right of the Company or any Subsidiary to terminate the
employment of the Optionee at any time. 


        9.    Notices.    Notices hereunder shall be mailed or delivered to the Company at its principal place of business and
shall be mailed or delivered to the Optionee at the address on file with the Company

        Pursuant
to the Helicos Biosciences Corporation 2007 Stock Option and Incentive Plan as amended through the date hereof (the "Plan"), Helicos Biosciences Corporation (the "Company")
hereby grants to the Optionee named above an option (the "Stock Option") to purchase on or prior to the Expiration Date specified above all or part of the number of shares of Common Stock, par value
$0.001 per share (the "Stock") of the Company specified above at the Option Exercise Price per Share specified above subject to the terms and conditions set forth herein and in the Plan. This Stock
Option is not intended to be an "incentive stock option" under Section 422 of the Internal Revenue Code of 1986, as amended. 



        1.    Exercisability Schedule.    No portion of this Stock Option may be exercised until such portion shall have
become exercisable. Except as set forth below, and subject to the discretion of the Administrator (as defined in Section 2 of the Plan) to accelerate the exercisability schedule hereunder, this
Stock Option shall be exercisable with respect to the following number of Option Shares on the dates indicated: 



			
	Incremental Number of

Option Shares Exercisable 	 	Exercisability Date 
	25% of Shares	 	One year from Vesting Start Date
	An additional 2.0833333% of the Shares	 	The first day of each month following the first anniversary of the Vesting Start Date.






        Once
exercisable, this Stock Option shall continue to be exercisable at any time or times prior to the close of business on the Expiration Date, subject to the provisions hereof and of
the Plan. 


        2.    Manner of Exercise.    


        (a)    The
Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the Expiration Date of this Stock Option, the Optionee may
give written notice to the Administrator of his or her election to purchase some or all of the Option Shares purchasable at the time of such notice. This notice shall specify the number of Option
Shares to be purchased. 


        Payment
of the purchase price for the Option Shares may be made by one or more of the following methods: (i) in cash, by certified or bank check or other instrument acceptable to
the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the Optionee on the open market or that are beneficially owned by
the Optionee and are not then subject to any restrictions under any Company plan and that otherwise satisfy any holding periods as may be required by the Administrator; (iii) by the Optionee
delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the
Company to pay the option purchase price, provided that in the event the Optionee chooses to pay the option purchase price as so provided, the Optionee and the broker shall comply with such procedures
and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as a condition 







 



of
such payment procedure; or (iv) a combination of (i), (ii) and (iii) above. Payment instruments will be received subject to collection. 



        The
transfer to the Optionee on the records of the Company or of the transfer agent of the Option Shares will be contingent upon (i) the Company's receipt from the Optionee of the
full purchase price for the Option Shares, as set forth above, (ii) the fulfillment of any other requirements contained herein or in the Plan or in any other agreement or provision of laws, and
(iii) the receipt by the Company of any agreement, statement or other evidence that the Company may require to satisfy itself that the issuance of Stock to be purchased pursuant to the exercise
of Stock Options under the Plan and any subsequent resale of the shares of Stock will be in compliance with applicable laws and regulations. In the event the Optionee chooses to pay the purchase price
by previously-owned shares of Stock through the attestation method, the number of shares of Stock transferred to the Optionee upon the exercise of the Stock Option shall be net of the Shares attested
to. 


        (b)    The
shares of Stock purchased upon exercise of this Stock Option shall be transferred to the Optionee on the records of the Company or of the transfer agent upon
compliance to the satisfaction of the Administrator with all requirements under applicable laws or regulations in connection with such issuance and with the requirements hereof and of the Plan. The
determination of the Administrator as to such compliance shall be final and binding on the Optionee. The Optionee shall not be deemed to be the holder of, or to have any of the rights of a holder with
respect to, any shares of Stock subject to this Stock Option unless and until this Stock Option shall have been exercised pursuant to the terms hereof, the Company or the transfer agent shall have
transferred the shares to the Optionee, and the Optionee's name shall have been entered as the stockholder of record on the books of the Company. Thereupon, the Optionee shall have full voting,
dividend and other ownership rights with respect to such shares of Stock. 


        (c)    The
minimum number of shares with respect to which this Stock Option may be exercised at any one time shall be 100 shares, unless the number of shares with respect to
which this Stock Option is being exercised is the total number of shares subject to exercise under this Stock Option at the time. 



        (d)    Notwithstanding
any other provision hereof or of the Plan, no portion of this Stock Option shall be exercisable after the Expiration Date hereof. 


        3.    Termination of Employment.    If the Optionee's employment by the Company or a Subsidiary (as defined in the
Plan) is terminated, the period within which to exercise the Stock Option may be subject to earlier termination as set forth below. 


        (a)    Termination Due to Death.    If the Optionee's employment terminates by reason of the Optionee's death, any
portion of this Stock Option outstanding on such date shall become fully exercisable and may thereafter be exercised by the Optionee's legal representative or legatee for a period of 12 months
from the date of death or until the Expiration Date, if earlier. 


        (b)    Termination Due to Disability.    If the Optionee's employment terminates by reason of the Optionee's
disability (as determined by the Administrator), any portion of this Stock Option outstanding on such date shall become fully exercisable and may thereafter be exercised by the Optionee for a period
of 12 months from the date of termination or until the Expiration Date, if earlier. 



        (c)    Termination for Cause.    If the Optionee's employment terminates for Cause, any portion of this Stock Option
outstanding on such date shall terminate immediately and be of no further force and effect. For purposes hereof, "Cause" shall mean, unless otherwise provided in an employment agreement between the
Company and the Optionee, a determination by the Administrator that the Optionee shall be dismissed as a result of (i) any material breach by the Optionee of any agreement between the Optionee
and the Company; (ii) the conviction of, indictment for or plea of nolo contendere by the Optionee to a felony or a crime involving moral turpitude; or (iii) any material 


2







 



misconduct
or willful and deliberate non-performance (other than by reason of disability) by the Optionee of the Optionee's duties to the Company. 


        (d)    Other Termination.    If the Optionee's employment terminates for any reason other than the Optionee's death,
the Optionee's disability or Cause, and unless otherwise determined by the Administrator, any portion of this Stock Option outstanding on such date may be exercised, to the extent exercisable on the
date of termination, for a period of three months from the date of termination or until the Expiration Date, if earlier. Any portion of this Stock Option that is not exercisable on the date of
termination shall terminate immediately and be of no further force or effect. 


        The
Administrator's determination of the reason for termination of the Optionee's employment shall be conclusive and binding on the Optionee and his or her representatives or legatees. 


        4.    Incorporation of Plan.    Notwithstanding anything herein to the contrary, this Stock Option shall be subject to
and governed by all the terms and conditions of the Plan, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized terms in this Agreement shall have the
meaning specified in the Plan, unless a different meaning is specified herein. 


        5.    Transferability.    This Agreement is personal to the Optionee, is non-assignable and is not
transferable in any manner, by operation of law or otherwise, other than by will or the laws of descent and distribution. This Stock Option is exercisable, during the Optionee's lifetime, only by the
Optionee, and thereafter, only by the Optionee's legal representative or legatee. 



        6.    Tax Withholding.    The Optionee shall, not later than the date as of which the exercise of this Stock Option
becomes a taxable event for Federal income tax purposes, pay to the Company or make arrangements satisfactory to the Administrator for payment of any Federal, state, and local taxes required by law to
be withheld on account of such taxable event. The Optionee may elect to have the minimum required tax withholding obligation satisfied, in whole or in part, by authorizing the Company to withhold from
shares of Stock to be issued a number of shares of Stock with an aggregate Fair Market Value that would satisfy the withholding amount due. 



        7.    No Obligation to Continue Employment.    Neither the Company nor any Subsidiary is obligated by or as a result
of the Plan or this Agreement to continue the Optionee in employment and neither the Plan nor this Agreement shall interfere in any way with the right of the Company or any Subsidiary to terminate the
employment of the Optionee at any time. 


        8.    Notices.    Notices hereunder shall be mailed or delivered to the Company at its principal place of business and
shall be mailed or delivered to the Optionee at the address on file with the Company or, in either case, at such other address as one party may subsequently furnish to the other party in writing.

Market Value that would satisfy the withholding amount due.

	Expiration Date: Ten Years from Grant Date	 	 






        Pursuant
to the Helicos Biosciences Corporation 2007 Stock Option and Incentive Plan as amended through the date hereof (the "Plan"), Helicos Biosciences Corporation (the "Company")
hereby grants to the Optionee named above, who is a Director of the Company but is not an employee of the Company, an option (the "Stock Option") to purchase on or prior to the Expiration Date
specified above all or part of the number of shares of Common Stock, par value $0.001 per share (the "Stock"), of the Company specified above at the Option Exercise Price per Share specified above
subject to the terms and conditions set forth herein and in the Plan. This Stock Option is not intended to be an "incentive stock option" under Section 422 of the Internal Revenue Code of 1986,
as amended. 


        1.    Exercisability Schedule.    No portion of this Stock Option may be exercised until such portion shall have
become exercisable. Except as set forth below, and subject to the discretion of the Administrator (as defined in Section 2 of the Plan) to accelerate the exercisability schedule hereunder, this
Stock Option shall be exercisable with respect to the following number of Option Shares on the dates indicated: 



			
	Incremental Number of

Option Shares Exercisable



 
	 	Exercisability Date 
	100% of Shares	 	One year from Vesting Start Date






        In
the event of the termination of the Optionee's service as a director of the Company because of death, this Stock Option shall become immediately exercisable in full, whether or not
exercisable at such time. Once exercisable, this Stock Option shall continue to be exercisable at any time or times prior to the close of business on the Expiration Date, subject to the provisions
hereof and of the Plan. 


        2.    Manner of Exercise.    



        (a)    The
Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the Expiration Date of this Stock Option, the Optionee may
give written notice to the Administrator of his or her election to purchase some or all of the Option Shares purchasable at the time of such notice. This notice shall specify the number of Option
Shares to be purchased. 


        Payment
of the purchase price for the Option Shares may be made by one or more of the following methods: (i) in cash, by certified or bank check or other instrument acceptable to
the Administrator; (ii) through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the Optionee on the open market or that are beneficially owned by
the Optionee and are not then subject to any restrictions under any Company plan and that otherwise satisfy any holding periods as may be required by the Administrator; (iii) by the Optionee
delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the
Company to pay the option purchase price, provided that in the event the Optionee chooses to pay the option purchase price as so provided, the Optionee and the broker shall comply with such procedures
and enter into 







 



such
agreements of indemnity and other agreements as the Administrator shall prescribe as a condition of such payment procedure; or (iv) a combination of (i), (ii) and
(iii) above. Payment instruments will be received subject to collection. 


        The
transfer to the Optionee on the records of the Company or of the transfer agent of the Option Shares will be contingent upon (i) the Company's receipt from the Optionee of the
full purchase price for the Option Shares, as set forth above, (ii) the fulfillment of any other requirements contained herein or in the Plan or in any other agreement or provision of laws, and
(iii) the receipt by the Company of any agreement, statement or other evidence that the Company may require to satisfy itself that the issuance of Stock to be purchased pursuant to the exercise
of Stock Options under the Plan and any subsequent resale of the shares of Stock will be in compliance with applicable laws and regulations. In the event the Optionee chooses to pay the purchase price
by previously-owned shares of Stock through the attestation method, the number of shares of Stock transferred to the Optionee upon the exercise of the Stock Option shall be net of the Shares attested
to. 


        (b)    The
shares of Stock purchased upon exercise of this Stock Option shall be transferred to the Optionee on the records of the Company or of the transfer agent upon
compliance to the satisfaction of the Administrator with all requirements under applicable laws or regulations in connection with such transfer and with the requirements hereof and of the Plan. The
determination of the Administrator as to such compliance shall be final and binding on the Optionee. The Optionee shall not be deemed to be the holder of, or to have any of the rights of a holder with
respect to, any shares of Stock subject to this Stock Option unless and until this Stock Option shall have been exercised pursuant to the terms hereof, the Company or the transfer agent shall have
transferred the shares to the Optionee, and the Optionee's name shall have been entered as the stockholder of record on the books of the Company. Thereupon, the Optionee shall have full voting,
dividend and other ownership rights with respect to such shares of Stock. 


        (c)    The
minimum number of shares with respect to which this Stock Option may be exercised at any one time shall be 100 shares, unless the number of shares with respect to
which this Stock Option is being exercised is the total number of shares subject to exercise under this Stock Option at the time. 


        (d)    Notwithstanding
any other provision hereof or of the Plan, no portion of this Stock Option shall be exercisable after the Expiration Date hereof. 


        3.    Termination as Director.    If the Optionee ceases to be a Director of the Company, the period within which to
exercise the Stock Option may be subject to earlier termination as set forth below. 



        (a)    Termination by Reason of Death.    If the Optionee ceases to be a Director by reason of the Optionee's death,
any portion of this Stock Option outstanding on such date may be exercised by his or her legal representative or legatee for a period of 12 months from the date of death or until the Expiration
Date, if earlier. 


        (b)    Other Termination.    If the Optionee ceases to be a Director for any reason other than the Optionee's death,
any portion of this Stock Option outstanding on such date may be exercised for a period of 12 months from the date of termination or until the Expiration Date, if earlier. 




        4.    Incorporation of Plan.    Notwithstanding anything herein to the contrary, this Stock Option shall be subject to
and governed by all the terms and conditions of the Plan, including the powers of the Administrator set forth in Section 2(b) of the Plan. Capitalized terms in this Agreement shall have the
meaning specified in the Plan, unless a different meaning is specified herein. 


        5.    Transferability.    This Agreement is personal to the Optionee, is non-assignable and is not
transferable in any manner, by operation of law or otherwise, other than by will or the laws of descent
and distribution. This Stock Option is exercisable, during the Optionee's lifetime, only by the Optionee, and thereafter, only by the Optionee's legal representative or legatee. 


2







 

        6.    No Obligation to Continue as a Director.    Neither the Plan nor this Stock Option confers upon the Optionee any
rights with respect to continuance as a Director. 


        7.    Notices.    Notices hereunder shall be mailed or delivered to the Company at its principal place of business and
shall be mailed or delivered to the Optionee at the address on file with the Company or, in either case, at such other address as one party may subsequently furnish to the other party in writing. 



        8.    Amendment.    Pursuant to Section 16 of the Plan, the Administrator may at any time amend or cancel any
outstanding portion of this Stock Option, but no such action may be taken that adversely affects the Optionee's rights under this Agreement without the Optionee's consent.
