Exhibit 10.3

PROS HOLDINGS, INC.
STOCK OPTION AGREEMENT

PROS Holdings, Inc. has granted to the Participant named in the Notice of Grant of Stock Option (the "Grant Notice") to which this Stock Option Agreement (the "Option Agreement") is attached an option (the "Option") to purchase certain shares of Stock upon the terms and conditions set forth in the Grant Notice and this Option Agreement. The Option has been granted pursuant to and shall in all respects be subject to the terms and conditions of the PROS Holdings, Inc. 2007 Equity Incentive Plan (the "Plan"), as amended to the Date of Grant, the provisions of which are incorporated herein by reference.  By signing the Grant Notice, the Participant: (a) acknowledges receipt of and represents that the Participant has read and is familiar with the Grant Notice, this Option Agreement, the Plan and a prospectus for the Plan prepared in connection with the registration with the Securities and Exchange Commission of shares issuable pursuant to the Option (the "Plan Prospectus"), (b) accepts the Option subject to all of the terms and conditions of the Grant Notice, this Option Agreement and the Plan and (c) agrees to accept as binding, conclusive and final all decisions or interpretations of the Committee upon any questions arising under the Grant Notice, this Option Agreement or the Plan.

1.     DEFINITIONS AND CONSTRUCTION.

1.1     Definitions. Unless otherwise defined herein, capitalized terms shall have the meanings assigned to such terms in the Grant Notice or the Plan.

1.2     Construction.  Captions and titles contained herein are for convenience only and shall not affect the meaning or interpretation of any provision of this Option Agreement.  Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular.  Use of the term "or" is not intended to be exclusive, unless the context clearly requires otherwise.

2.    TAX CONSEQUENCES.

2.1     Tax Status of Option.  This Option is intended to have the tax status designated in the Grant Notice.

(a)     Incentive Stock Option.  If the Grant Notice so designates, this Option is intended to be an Incentive Stock Option within the meaning of Section 422(b) of the Code, but the Company does not represent or warrant that this Option qualifies as such.  The Participant should consult with the Participant's own tax advisor regarding the tax effects of this Option and the requirements necessary to obtain favorable income tax treatment under

1

Section 422 of the Code, including, but not limited to, holding period requirements. (NOTE TO PARTICIPANT: If the Option is exercised more than three (3) months after the date on which you cease to be an Employee (other than by reason of your death or permanent and total disability as defined in Section 22(e) (3) of the Code), the Option will be treated as a Nonstatutory Stock Option and not as an Incentive Stock Option to the extent required by Section 422 of the Code.)

(b)     Nonstatutory Stock Option. If the Grant Notice so designates,  this Option is intended to be a Nonstatutory Stock Option and shall not be treated as an Incentive Stock Option within the meaning of Section 422(b) of the Code.

2.2     ISO Fair Market Value Limitation. If the Grant Notice designates  this Option as an Incentive Stock Option, then to the extent that the Option (together with all Incentive Stock Options granted to the Participant under all stock option plans of the Participating Company Group, including the Plan) becomes exercisable for the first time during any calendar year for shares having a Fair Market Value greater than One Hundred Thousand Dollars ($100,000), the portion of such options which exceeds such amount will be treated as Nonstatutory Stock Options.  For purposes of this Section 2.2, options designated as Incentive Stock Options are taken into account in the order in which they were granted, and the Fair Market Value of stock is determined as of the time the option with respect to such stock is granted.  If the Code is amended to provide for a different limitation from that set forth in this Section 2.2, such different limitation shall be deemed incorporated herein effective as of the date required or permitted by such amendment to the Code.  If the Option is treated as an Incentive Stock Option in part and as a Nonstatutory Stock Option in part by reason of the limitation set forth in this Section 2.2, the Participant may designate which portion of such Option the Participant is exercising.  In the absence of such designation, the Participant shall be deemed to have exercised the Incentive Stock Option portion of the Option first.  Separate certificates representing each such portion shall be issued upon the exercise of the Option.  (NOTE TO PARTICIPANT:  If the aggregate Exercise Price of the Option (that is, the Exercise Price multiplied by the Number of Option Shares) plus the aggregate exercise price of any other Incentive Stock Options you hold (whether granted pursuant to the Plan or any other stock option plan of the Participating Company Group) is greater than $100,000, you should contact the Chief Financial Officer of the Company to ascertain whether the entire Option qualifies as an Incentive Stock Option.)

3.    ADMINISTRATION.

All questions of interpretation concerning this Option Agreement shall be determined by the Committee.  All determinations by the Committee shall be final and binding upon all persons having an interest in the Option as provided by the Plan.  Any Officer shall have the authority to act on behalf of the Company with respect to any matter, right, obligation, or election which is the responsibility of or which is allocated to the Company herein, provided the Officer has apparent authority with respect to such matter, right, obligation, or election.

4.     EXERCISE OF THE OPTION.

4.1     Right to Exercise.  Except as otherwise provided herein, the Option shall be exercisable on and after the Initial Vesting Date and prior to the termination of the Option (as provided in Section 6) in an amount not to exceed the number of Vested Shares less the number of shares previously acquired upon exercise of the Option.  In no event shall the Option be exercisable for more shares than the Number of Option Shares, as adjusted pursuant to Section 9.

4.2     Method of Exercise.  Exercise of the Option shall be by means of electronic or written notice (the "Exercise Notice") in a form authorized by the Company.  An electronic Exercise Notice must be digitally signed or authenticated by the Participant in such manner as required by the notice and transmitted to the Company or an authorized representative of the Company (including a third-party administrator designated by the Company).  In the event that the Participant is not authorized or is unable to provide an electronic Exercise Notice, the Option shall be exercised by a written Exercise Notice addressed to the Company, which shall be signed by the Participant and delivered in person, by certified or registered mail, return receipt requested, by confirmed facsimile transmission, or by such other means as the Company may permit, to the Company, or an authorized representative of the Company (including a third-party administrator designated by the Company).  Each Exercise Notice, whether electronic or written, must state the Participant's election to exercise the Option, the number of whole shares of Stock for which the Option is being exercised and such other representations and agreements as to the Participant's investment intent with respect to such shares as may be required pursuant to the provisions of this Option Agreement.  Further, each Exercise Notice must be received by the Company prior to the termination of the Option as set forth in Section 6 and must be accompanied by full payment of the aggregate Exercise Price for the number of shares of Stock being purchased.  The Option shall be deemed to be exercised upon receipt by the Company of such electronic or written Exercise Notice and the aggregate Exercise Price.

4.3     Payment of Exercise Price.

(a)     Forms of Consideration Authorized. Except as otherwise provided below, payment of the aggregate Exercise Price for the number of shares of Stock for which the Option is being exercised shall be made (i) in cash or by check or cash equivalent, (ii) if permitted by the Company, by tender to the Company, or attestation to the ownership, of whole shares of Stock owned by the Participant having a Fair Market Value not less than the aggregate Exercise Price, (iii) by means of a Cashless Exercise, as defined in Section 4.3(b), or (iv) by any combination of the foregoing.

(b)     Limitations on Forms of Consideration.

(i)     Tender of Stock.  Notwithstanding the foregoing, the Option may not be exercised by tender to the Company, or attestation to the ownership, of 

3

shares of Stock to the extent such tender or attestation would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock.  If required by the Company, the Option may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock unless such shares either have been owned by the Participant for more than six (6) months or such other period, if any, required by the Company (and not used for another option exercise by attestation during such period) or were not acquired, directly or indirectly, from the Company.

(ii)     Cashless Exercise.  A "Cashless Exercise" means the delivery of a properly executed notice together with irrevocable instructions to a broker in a form acceptable to the Company providing for the assignment to the Company of the proceeds of a sale or loan with respect to some or all of the shares of Stock acquired upon the exercise of the Option pursuant to a program or procedure approved by the Company (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System).  The Company reserves, at any and all times, the right, in the Company's sole and absolute discretion, to establish, decline to approve or terminate any such program or procedure, including with respect to the Participant notwithstanding that such program or procedures may be available to others.

4.4     Tax Withholding.

(a)     In General. At the time the Option is exercised, in whole or in part, or at any time thereafter as requested by the Company, the Participant hereby authorizes withholding from payroll and any other amounts payable to the Participant, and otherwise agrees to make adequate provision for (including by means of a Cashless Exercise to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Participating Company Group, if any, which arise in connection with the Option.  The Company shall have no obligation to deliver shares of Stock until the tax withholding obligations of the Participating Company Group have been satisfied by the Participant.

(b)     Withholding in Shares. The Company may permit or require the Participant to satisfy all or any portion of a Participating Company's tax withholding obligations upon exercise of the Option by deducting from the shares of Stock otherwise issuable to the Participant upon such exercise a number of whole shares having a fair market value, as determined by the Company as of the date of exercise, not in excess of the amount of such tax withholding obligations determined by the applicable minimum statutory withholding rates.  Any adverse consequences to the Participant resulting from the procedure permitted under this Section, including, without limitation, tax consequences, shall be the sole responsibility of the Participant.

4

4.5     Beneficial Ownership of Shares; Certificate Registration.  The Participant hereby authorizes the Company, in its sole discretion, to deposit for the benefit of the Participant with any broker with which the Participant has an account relationship of which the Company has notice any or all shares acquired by the Participant pursuant to the exercise of the Option.  Except as provided by the preceding sentence, a certificate for the shares as to which the Option is exercised shall be registered in the name of the Participant, or, if applicable, in the names of the heirs of the Participant.

4.6     Restrictions on Grant of the Option and Issuance of Shares.  The grant of the Option and the issuance of shares of Stock upon exercise of the Option shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities.  The Option may not be exercised if the issuance of shares of Stock upon exercise would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Stock may then be listed.  In addition, the Option may not be exercised unless (i) a registration statement under the Securities Act shall at the time of exercise of the Option be in effect with respect to the shares issuable upon exercise of the Option or (ii) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Option may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. THE PARTICIPANT IS CAUTIONED THAT THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED.  ACCORDINGLY, THE PARTICIPANT MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company's legal counsel to be necessary to the lawful issuance and sale of any shares subject to the Option shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to the exercise of the Option, the Company may require the Participant to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company.

4.7     Fractional Shares. The Company shall not be required to issue fractional shares upon the exercise of the Option.

5.     NONTRANSFERABILITY OF THE OPTION.

During the lifetime of the Participant, the Option shall be exercisable only by the Participant or the Participant's guardian or legal representative.  The Option shall not be subject in any manner  to anticipation, alienation,  sale, exchange, transfer,  assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant's beneficiary, except  transfer  by will or by the laws of descent  and distribution.  Following the death of the Participant, the Option,  to the extent provided  in Section  7, may be 

5

exercised by the Participant's legal representative or by any person empowered to do so under the deceased  Participant's will or under the then applicable laws of descent  and distribution.

6.     TERMINATION OF THE OPTION.

The Option shall terminate and may no longer be exercised after the first to occur of (a) the close of business on the Option Expiration Date, (b) the close of business on the last date for exercising the Option following termination of the Participant's Service as described in Section 7, or (c) a Change in Control to the extent provided in Section 8.

7.     EFFECT OF TERMINATION OF SERVICE.

7.1     Option Exercisability. The Option shall terminate immediately upon the Participant's termination of Service to the extent that it is then unvested  and shall be exercisable after the Participant's termination of Service  to the extent it is then vested only during  the applicable time period  as determined  below  and thereafter shall terminate.

(a)     Disability. If the Participant's Service terminates because of the Disability of the Participant, the Option, to the extent unexercised and exercisable for Vested Shares on the date on which the Participant's Service terminated, may be exercised by the Participant (or the Participant's guardian or legal representative) at any time prior to the expiration of twelve (12) months after the date on which the Participant's Service terminated, but in any event no later than the Option Expiration Date.

(b)        Death. If the Participant's Service terminates because of the death of the Participant, the Option,  to the extent  unexercised and exercisable for Vested  Shares on the date on which the Participant's Service  terminated, may be exercised  by the Participant's legal representative or other person who acquired the right to exercise the Option by reason of the Participant's  death at any time prior to the expiration of twelve (12) months after the date on which the Participant's  Service terminated, but in any event no later than the Option Expiration Date.  The Participant’s Service shall be deemed to have terminated on account of death if the Participant dies within three (3) months after the Participant’s termination of Service.

(c)     Termination for Cause. If the Participant's Service is terminated for Cause or if, following the Participant’s termination of Service and during any period in which the Option otherwise would remain exercisable, the Participant engages in any act that would constitute Cause, the Option shall terminate in its entirety and cease to be exercisable immediately upon such termination of Service or act.

(d)     Other Termination of Service. If the Participant's Service terminates for any reason, except Disability, death or Cause, the Option, to the extent unexercised and exercisable for Vested Shares by the Participant on the date on which the Participant’s Service terminated, may be exercised by the Participant at any time prior to 

6

the expiration of three (3) months after the date on which the Participant’s Service terminated, but in any event no later than the Option Expiration Date.

7.2     Extension if Exercise Prevented by Law or Insider Trading Policy. Notwithstanding the foregoing, other than termination of Service for Cause, if the exercise of the Option within the applicable time periods set forth in Section 7.1 is prevented by the provisions of Section 4.6 or a sale of shares pursuant to a Cashless Exercise of the Option would violate the provisions of the Insider Trading Policy, the Option shall remain exercisable until thirty (30) days after the date such exercise or sale, as the case may be, would no longer be prevented by such provisions, but in any event no later than the Option Expiration Date.

8.     EFFECT OF CHANGE IN CONTROL.

In the event of a Change in Control, except to the extent that the Committee determines to cash out the Option in accordance with Section 15.1(d) of the Plan, the surviving, continuing, successor, or purchasing entity or parent thereof, as the case may be (the "Acquiror "), may, without the consent of any Participant, either assume or continue the Company's rights and obligations under each or any Award or portion thereof outstanding immediately prior to the Change in Control or substitute for each or any such outstanding Award or portion thereof a substantially equivalent award with respect to the Acquiror's stock, as applicable.  For purposes of this Section, if so determined by the Committee, in its discretion, an Award denominated in shares of Stock shall be deemed assumed if, following the Change in Control, the Award confers the right to receive, subject to the terms and conditions of the Plan and the applicable Award Agreement, for each share of Stock subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, other securities or property or a combination thereof) to which a holder of a share of Stock on the effective date of the Change in Control was entitled; provided, however, that if such consideration  is not solely common stock of the Acquiror, the Committee may, with the consent of the Acquiror, provide for the consideration to be received upon the exercise or settlement of the Award, for each share of Stock subject to the Award, to consist solely of common stock of the Acquiror equal in Fair Market Value to the per share consideration received by holders of Stock pursuant to the Change in Control.  Any Award or portion thereof which is neither assumed or continued by the Acquiror in connection with the Change in Control nor exercised or settled as of the time of consummation of the Change in Control shall become immediately exercisable and vested in full (a) as often (1) days prior to, and subject to, the consummation of the Change in Control or (b) settled effective immediately prior to the time of consummation of the Change in Control, as applicable.  Any Award or portion thereof that is immediately exercisable and vested in full pursuant to the preceding sentence to the extent unexercised immediately prior to the consummation of the Change in Control shall terminate and cease to be outstanding effective as of the time of the consummation of the Change in Control.

7

Notwithstanding  any other provision of the Plan to the contrary, if the Participant's Service is terminated without Cause or the Participant voluntarily terminates the Participant's employment  after a reduction of the Participant's base salary of :fifteen percent (15%) or greater without the Participant's  express written consent within eighteen (18) months following the consummation  of a Change in Control, such Participant's Awards shall become immediately exercisable and vested in full as of the date of such termination.  Such immediately exercisable and fully vested Awards shall be settled to the extent possible on the date of the Participant's termination pursuant to this subsection (c).  Awards requiring the Participant's exercise may be exercised by the Participant at any time prior to the expiration of three (3) months after the date on which the Participant’s Service terminated, but in any event no later than the Option Expiration Date.

9.     ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE.

Subject to any required action by the stockholders of the Company, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar change in the capital structure of the Company, or in the event of payment of a dividend or distribution to the stockholders of the Company in a form other than Stock (excepting normal cash dividends) that has a material effect on the Fair Market Value of shares of Stock, appropriate and proportionate adjustments shall be made in the number, Exercise Price and kind of shares subject to the Option, in order to prevent dilution or enlargement of the Participant's rights under the Option.  For purposes of the foregoing, conversion of any convertible securities of the Company shall not be treated as "effected without receipt of consideration by the Company."  Any fractional share resulting from an adjustment pursuant to this Section shall be rounded down to the nearest whole number, and in no event may the Exercise Price be decreased to an amount less than the par value, if any, of the stock subject to the Option.  The Committee in its sole discretion, may also make such adjustments in the terms of the Option to reflect, or related to, such changes in the capital structure of the Company or distributions as it deems appropriate.  The adjustments determined by the Committee pursuant to this Section shall be final, binding and conclusive.

10.     RIGHTS AS A STOCKHOLDER, DIRECTOR, EMPLOYEE OR CONSULTANT.

The Participant shall have no rights as a stockholder with respect to any shares covered by the Option until the date of the issuance of the shares for which the Option has been exercised (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company).  No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date the shares are issued, except as provided in Section 9.  If the Participant is an Employee, the Participant understands and acknowledges that, except as otherwise provided in a separate, 

8

written employment agreement between a Participating Company and the Participant, the Participant's employment is "at will" and is for no specified term.  Nothing in this Option Agreement shall confer upon the Participant any right to continue in the Service of a Participating Company or interfere in any way with any right of the Participating Company Group to terminate the Participant's Service as a Director, an Employee or Consultant, as the case may be, at any time.

11.     NOTICE OF SALES UPON DISQUALIFYING DISPOSITION.

The Participant shall dispose of the shares acquired pursuant to the Option only in accordance with the provisions of this Option Agreement.  In addition, if the Grant Notice designates this Option as an Incentive Stock Option, the Participant shall (a) promptly notify the Chief Financial Officer of the Company if the Participant disposes of any of the shares acquired pursuant to the Option within one (1) year after the date the Participant exercises all or part of the Option or within two (2) years after the Date of Grant and (b) provide the Company with a description of the circumstances of such disposition.  Until such time as the Participant disposes of such shares in a manner consistent with the provisions of this Option Agreement, unless otherwise expressly authorized by the Company, the Participant shall hold all shares acquired pursuant to the Option in the Participant’s name (and not in the name of any nominee) for the one-year period immediately after the exercise of the Option and the two-year period immediately after Date of Grant.  At any time during the one-year or two-year periods set forth above, the Company may place a legend on any certificate representing shares acquired pursuant to the Option requesting the transfer agent for the Company's stock to notify the Company of any such transfers.  The obligation of the Participant to notify the Company of any such transfer shall continue notwithstanding that a legend has been placed on the certificate pursuant to the preceding sentence.

12.     LEGENDS.

The Company may at any time place legends referencing any applicable federal, state or foreign securities law restrictions on all certificates representing shares of stock subject to the provisions of this Option Agreement.  The Participant shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to the Option in the possession of the Participant in order to carry out the provisions of this Section.  Unless otherwise specified by the Company, legends placed on such certificates may include, but shall not be limited to, the following:

12.1     ''THE   SECURITIES   EVIDENCED   BY  THIS  CERTIFICATE   HAVE NOT BEEN REGISTERED UNDER THE SECURITIES  ACT OF 1933, AS AMENDED,  AND MAY  NOT   BE   SOLD,   TRANSFERRED,   ASSIGNED   OR  HYPOTHECATED UNLESS THERE  IS  AN  EFFECTIVE  REGISTRATION   STATEMENT  UNDER  SUCH  ACT COVERING  SUCH  SECURITIES,  THE SALE IS MADE  IN ACCORDANCE  WITH  RULE 144 OR RULE 701 UNDER THE ACT, OR THE COMPANY RECEIVES AN OPINION OFCOUNSEL REASONABLY SATISFACTORY TO THE COMPANY, STATING THAT SUCH 

9

SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT."

12.2   "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER IN FAVOR OF THE CORPORATION OR ITS ASSIGNEE SET FORTH IN AN AGREEMENT BETWEEN THE CORPORATION AND THE REGISTERED HOLDER, OR SUCH HOLDER'S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THIS CORPORATION."

12.3     ''THE SHARES EVIDENCED BY THIS CERTIFICATE WERE ISSUED BY THE CORPORATION TO THE REGISTERED HOLDER UPON EXERCISE OF AN INCENTIVE STOCK OPTION AS DEFINED IN SECTION 422 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED ("ISO").  IN ORDER TO OBTAIN THE PREFERENTIAL TAX TREATMENT AFFORDED TO ISOs, THE SHARES SHOULD NOT BE TRANSFERRED PRIOR TO [INSERT DISQUALIFYING DISPOSITION DATE HERE]. SHOULD THE REGISTERED HOLDER ELECT TO TRANSFER ANY OF THE SHARES PRIOR TO THIS DATE AND FOREGO ISO TAX TREATMENT, THE TRANSFER AGENT FOR THE SHARES SHALL NOTIFY THE CORPORATION IMMEDIATELY. THE REGISTERED HOLDER SHALL HOLD ALL SHARES PURCHASED UNDER THE INCENTIVE STOCK OPTION IN THE REGISTERED HOLDER'S NAME (AND NOT IN THE NAME OF ANY NOMINEE) PRIOR TO THIS DATE OR UNTIL TRANSFERRED AS DESCRIBED ABOVE."

13.     RIGHT OF FIRST REFUSAL.

13.1    Grant of Right of First Refusal.   Except as provided in Section 13.7 below, in the event the Participant, the Participant's  legal representative, or other holder of shares acquired upon exercise of the Option proposes to sell, exchange, transfer, pledge, or otherwise  dispose of  any Vested  Shares  or  any Unvested  Shares  (together, the  "Transfer Shares") to any person or entity, including, without limitation, any shareholder of the Company, the Company shall have the right to repurchase the Transfer Shares under the terms and subject to the conditions set forth in this Section 13 (the "Right of First Refusal").

13.2    Notice of Proposed Transfer.    Prior to any proposed transfer of the Transfer Shares, the Participant shall deliver written notice (the "Transfer Notice") to the Company describing fully the proposed transfer, including the number of Transfer Shares, the name and address of the proposed transferee (the "Proposed Transferee") and, if the transfer is voluntary, the proposed transfer price, and containing such information necessary to show the bona fide nature of the proposed transfer.  In the event of a bona fide gift or involuntary transfer, the proposed transfer price shall be deemed to be the fair market value of the Transfer Shares, as determined by the Board or the Committee in good faith. If the Participant proposes to transfer any Transfer Shares to more than one Proposed Transferee, the Participant shall provide a separate Transfer Notice for the proposed transfer to each Proposed Transferee.  The Transfer Notice shall 

10

be signed by both the Participant and the Proposed Transferee and must constitute a binding commitment of the Participant and the Proposed Transferee for the transfer of the Transfer Shares to the Proposed Transferee subject only to the Right of First Refusal.

13.3    Bona Fide Transfer.  If the Company determines that the information provided by the Participant in the Transfer Notice is insufficient to establish the bona fide nature of a proposed voluntary transfer, the Company shall give the Participant written notice of the Participant's  failure  to  comply  with  the  procedure  described  in  this  Section 13,  and  the Participant shall have no right to transfer the Transfer Shares without first complying with the procedure described in this Section 13.   The Participant shall not be permitted to transfer the Transfer Shares if the proposed transfer is not bona fide.

13.4    Exercise of Right of First Refusal.  If the Company determines the proposed transfer to be bona fide, the Company shall have the right to purchase all, but not less than all, of the Transfer Shares (except as the Company and the Participant otherwise agree) at the purchase price and on the terms set forth in the Transfer Notice by delivery to the Participant of a notice of exercise of the Right of First Refusal within thirty (30) days after the date the Transfer Notice is delivered to the Company. The Company's exercise or failure to exercise the Right of First Refusal with respect to any proposed transfer described in a Transfer Notice shall not affect the Company's right to exercise the Right of First Refusal with respect to any proposed transfer described in any other Transfer Notice, whether or not such other Transfer Notice is issued by the Participant or issued by a person other than the Participant with respect to a proposed transfer to the same Proposed Transferee.  If the  Company exercises the Right of First Refusal, the Company and the Participant shall thereupon consummate the sale of the Transfer Shares to the Company on the terms set forth in the Transfer Notice within sixty (60) days after the date the Transfer Notice is delivered to the Company (unless a longer period is offered by the Proposed Transferee); provided, however, that in the event the Transfer Notice provides for the payment for the Transfer Shares other than in cash, the Company shall have the option of paying for the Transfer Shares by the present value cash equivalent of the consideration described in the Transfer Notice as reasonably determined by the Company.  For purposes of the foregoing, cancellation of any indebtedness of the Participant to the Company shall be treated as payment to the Participant in cash to the extent of the unpaid principal and any accrued interest canceled.

13.5    Failure to Exercise Right of First Refusal.  If the Company fails to exercise the Right of First Refusal in full (or to such lesser extent as the Company and the Participant otherwise agree) within the period specified in Section 13.4 above, the Participant may conclude a transfer to the Proposed Transferee of the Transfer Shares on the terms and conditions described in the Transfer Notice, provided such transfer occurs not later than ninety (90) days following delivery to the Company of the Transfer Notice.  The Company shall have the right to demand further assurances from the Participant and the Proposed Transferee (in a form satisfactory to the Company) that the transfer of the Transfer Shares was actually carried out on the terms and conditions described in the Transfer Notice.  No Transfer Shares shall be transferred on the books of the Company until the Company has received such assurances, if so demanded, and has approved the proposed transfer as bona fide. Any proposed transfer on terms and conditions different from 

11

those described in the Transfer Notice, as well as any subsequent proposed transfer by the Participant, shall again be subject to the Right of First Refusal and shall require compliance by the Participant with the procedure described in this Section 13.

13.6    Transferees of Transfer Shares.  All transferees of the Transfer Shares or any interest therein, other than the Company, shall be required as a condition of such transfer to agree in writing (in a form satisfactory to the Company) that such transferee shall receive and hold such Transfer  Shares or  interest therein subject  to all of the terms and conditions of this Option  Agreement,  including  this  Section  13 providing  for  the  Right  of  First  Refusal  with respect to any subsequent  transfer.   Any sale or transfer of any shares acquired upon exercise of the Option shall be void unless the provisions of this Section 13 are met.

13.7    Transfers Not Subject to Right of First Refusal.  The Right of First Refusal shall not apply to any transfer or exchange of the shares acquired upon exercise of the Option if such transfer or exchange is in connection with an Ownership Change Event.   If the consideration received pursuant to such transfer or exchange consists of stock of the Company, such consideration shall remain subject to the Right of First Refusal unless the provisions of Section 13.9 below result in a termination of the Right of First Refusal.

13.8    Assignment of Right of First Refusal.  The Company shall have the right to assign the Right of First Refusal at any time, whether or not there has been an attempted transfer, to one or more persons as may be selected by the Company.

13.9    Early Termination of Right of First Refusal.   The other  provisions of this Option Agreement  notwithstanding,  the Right of First Refusal shall terminate  and be of no further  force  and effect  upon  (a) the occurrence  of a Change  in Control,  unless  the Acquiror assumes the Company's rights and obligations under the Option or substitutes a substantially equivalent option for the Acquiror's stock for the Option, or (b) the existence of a public market for the class of shares subject to the Right of First Refusal.  A "public market" shall be deemed to exist if (i) such stock  is listed on a national securities  exchange  (as that term is used in the Exchange Act) or (ii) such stock is traded on the over-the-counter  market and prices therefor are published daily on business days in a recognized financial journal.

14.     LOCK-UP AGREEMENT.

The Participant hereby agrees that in the event of any underwritten public offering of stock,  including  an  initial  public offering  of  stock,  made  by the Company  pursuant  to  an effective registration statement  filed under the Securities Act, the Participant shall not offer, sell, contract to sell, pledge, hypothecate,  grant any option to purchase or make any short sale of, or otherwise dispose of any shares of stock of the Company or any rights to acquire stock of the Company for such period of time from and after the effective date of such registration statement as may be established  by the underwriter  for such public offering; provided, however, 

12

that such period of time shall not exceed one hundred eighty (180) days from the effective date of the registration  statement to be filed in connection with such public offering.   The foregoing limitation shall not apply to shares registered in the public offering under the Securities Act.

15.     REPRESENTATIONS AND WARRANTIES.

In connection with the receipt of the Option and any acquisition of shares upon the exercise thereof (collectively, the "Securities"), the Participant hereby agrees, represents and warrants as follows:

15.1    Investment Intent.  The Participant is acquiring the Securities solely for the Participant’s own account for investment and not with a view to or for sale in connection with any distribution of the Securities or any portion thereof and not with any present intention of selling, offering to sell or otherwise disposing of or distributing the Securities or any portion thereof in any transaction other than a transaction exempt from registration under the Securities Act.    The  Participant  further represents that  the  entire legal  and  beneficial  interest  of  the Securities is being acquired, and will be held, for the account of the Participant only and neither in whole nor in part for any other person.

15.2    Absence   of Solicitation.   The  Participant  was  not  presented  with  or solicited by any form of general solicitation or general advertising, including, but not limited to, any  advertisement,  article,  notice,  or  other  communication  published  in  any  newspaper, magazine, or similar media, or broadcast over television, radio or similar communications media, or presented at any seminar or meeting whose attendees have been invited by any general solicitation or general advertising.

15.3    Residence.  The Participant's principal residence is located at the address indicated beneath the Participant's signature on the Grant Notice.

15.4    Information Concerning the Company. The Participant is aware of the Company's business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities.   The Participant further represents and warrants that the Participant has discussed the Company and its plans, operations and financial condition with its Officers, has received all such information as the  Participant  deems  necessary  and  appropriate  to  enable the  Participant  to  evaluate  the financial risk inherent in acquiring the Securities and has received satisfactory and complete information concerning the business and financial condition of the Company in response to all inquiries in respect thereof

15.5    Economic Risk.     The Participant realizes that his acquisition of the Securities will be a highly speculative investment and that the Participant is able, without impairing 

13

his or her financial condition, to hold the Securities for an indefinite period of time and to suffer a complete loss on the Participant's investment.

15.6    Capacity to Protect Interests.  The  Participant  has  (i) a  preexisting personal or business relationship with the Company or any  of its Officers, directors, or controlling persons, consisting of personal or business contacts of a nature and duration to enable the Participant to be aware of the character, business acumen and general business and financial circumstances of the person with whom such relationship exists, or  (ii) such knowledge  and experience in financial and business matters as to make the Participant capable of evaluating the merits and risks of an investment in the Securities and to protect the Participant's own interests in the transaction, or (iii) both such relationship and such knowledge and experience.

15.7   Restricted Securities.     The Participant understands and acknowledges that:

(a) The issuance of the Securities to the Participant has not been registered under  the Securities  Act,  and the Securities  must  be held indefinitely  unless  a transfer  of the Securities   is  subsequently   registered  under  the  Securities  Act  or  an  exemption   from  such registration is available, and that the Company is under no obligation to register the Securities;

(b) The Company will make a notation in its records of the aforementioned restrictions on transfer and legends.

15.8     Disposition Under Rule 144 and/or 701.    The  Participant  understands that  any shares  acquired  upon  exercise  of  the  Option  will  be  restricted  securities  within  the meaning of Rule 144 promulgated under the Securities Act; that the exemption from registration under  Rule  144  will  not  be  available  in  any  event  for  at  least  one  year  from  the  date  of acquisition  of the shares, and even then will not be available unless (a) a public trading market then  exists  for the Common  Stock  of the  Company,  (b) adequate  information  concerning  the Company  is then  available  to the public,  and (c) other  terms  and conditions  of  Rule 144  are complied  with;  and  that  any  sale  of  the  shares  may  be  made  only  in  limited  amounts  in accordance with such terms and conditions.  The Participant further understands that the resale provisions of Rule 701, if available, will not apply until 90 days after the Company becomes subject to the reporting obligation under the Exchange Act.  There can be no assurance that the requirements of Rule 144 or Rule 701 will be met, or that the shares will ever be salable.

15.9    Further Limitations on Disposition.   Without in any way limiting the Participant's representations and warranties set forth above, the Participant further agrees that the Participant will in no event make any disposition of all or any portion of any shares which the Participant acquires upon exercise of the Option unless:

14

(a) There  is then  in effect  a Registration  Statement  under the Securities Act covering such proposed disposition and such disposition is made in accordance with said Registration Statement; or

(b) The  Participant   will  have  notified  the  Company  of  the  proposed disposition   and   furnished   the  Company   with   a  detailed   statement   of  the   circumstances surrounding  the proposed disposition, and either:

(i)        The Participant  will have  furnished the Company  with an opinion  of  the  Participant's own  counsel  to  the  effect  that  such  disposition  will  not  require registration of such shares under the Securities Act, and such opinion of the Participant's counsel will have been concurred in by counsel for the Company and the Company will have advised the Participant of such concurrence; or

(ii)  The disposition is made in compliance with Rule 144 and/or Rule 701 after the Participant has furnished the Company such detailed statement and after the Company has had a reasonable opportunity to discuss the matter with the Participant.
15.10   Reliance by Company. The Participant understands that the Company is relying on the Participant’s representations and warrants that the Company is entitled to rely on such representations and that such reliance is reasonable.

16.     MISCELLANEOUS PROVISIONS.

16.1     Termination or Amendment.

 and shall not affect the meaning or interpretation of any provision of this Agreement.

	3.
	EXERCISE OF THE AWARD.

		
	3.1
	Right to Exercise. Except as otherwise provided herein, the Award shall

 be exercisable on and after the Initial Vesting Date and prior to the termination of the Award (as provided in Section 5) in an amount not to exceed the number of Vested Rights less the number of Rights for which the Award was previously exercised. In no event shall the Award be exercisable for more than the total Number of Rights awarded, as adjusted pursuant to Section 8.

		
	3.2
	Method of Exercise. Exercise of the Award shall be by means of 

2

electronic or written notice (the "Exercise Notice") in a form authorized by the Company. An electronic Exercise Notice must be digitally signed or authenticated by the Participant in such manner as required by the notice and transmitted to the Company or an authorized representative of the Company (including a third-party administrator designated by the Company). In the event that the Participant is not authorized or is unable to provide an electronic Exercise Notice, the Award shall be exercised by a written Exercise Notice addressed to the Company, which shall be signed by the Participant and delivered in person, by certified or registered mail, return receipt requested, by confirmed facsimile transmission, or by such other means as the Company may permit, to the Company, or an authorized representative of the Company (including a third-party administrator designated by the Company).

	Deemed Exercise of the Award.  If, on the date on which Award would 

otherwise terminate or expire (other than as a result of termination of the Participant's Service for Cause), the Award remains exercisable immediately prior to such termination or expiration and, if so exercised, would result in a payment to the holder of the Award, then any portion of the Award which has not previously been exercised and which is then exercisable shall automatically be deemed to be exercised with respect to such portion as of such date, which shall be treated as the Exercise Date.

		
	3.4
	Payment Upon Exercise of Rights. Upon the exercise (or deemed exercise 

pursuant to Section 3.3) of one or more Rights in accordance with the terms of this Agreement, the Participant (or the Participant's legal representative or other person who acquired the right to exercise such Rights by reason of the Participant's death) shall be entitled to receive payment of an amount for each Right exercised equal to the excess, if any, of the Fair Market Value on the Exercise Date of one (1) share of Stock over the Exercise Price (the "Spread"). No adjustment or payment shall be made for dividends declared with respect to the Stock, except as may be provided by Section 8. Payment of the aggregate Spread for the number of Rights exercised shall be made as soon as practicable following the Exercise Date by the issuance of a number of shares of Stock determined by dividing the aggregate Spread for the number of Rights exercised by the Fair Market Value on the Exercise Date of a share of Stock.

3

		
	3.5
	Tax Withholding.

		
	(a)
	In General. At the time the Award is exercised, in whole or in part, or at any

 time thereafter as requested by a Participating Company, the Participant hereby authorizes withholding from payroll and any other amounts payable to the Participant pursuant to the Award or otherwise, and otherwise agrees to make adequate provision for, any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Participating Company, if any, which arise in connection with the Award.  The Company shall have no obligation to deliver shares of Stock until the tax withholding obligations of the Participating Company have been satisfied by the Participant.

		
	(b)
	Withholding in Shares. The Company shall have the right, but not the 

obligation, to require the Participant to satisfy all or any portion of a Participating Company's tax withholding obligations upon exercise of the Award withholding a number of whole shares of Stock otherwise deliverable to the Participant upon the exercise of the Award having a fair market value, as determined by the Company as of the date of exercise, not in excess of the amount of such tax withholding obligations determined by the applicable minimum statutory withholding rates.

		
	3.6
	Beneficial Ownership of Shares; Certificate Registration. In the event that

 payment upon exercise of the Award is made in full or in part in shares of Stock, the Participant hereby authorizes the Company, in its sole discretion, to deposit for the benefit of the Participant with any broker with which the Participant has an account relationship of which the Company has notice any or all shares acquired by the Participant. Except as provided by the preceding sentence, a certificate for the shares issued upon exercise of the Award shall be registered in the name of the Participant, or, if applicable, in the names of the heirs of the Participant.

		
	3.7
	Restrictions on Grant of the Award and Issuance of Shares. The grant of the 

Award and the issuance of shares of Stock upon exercise of the Award shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities. The Award may not be exercised if the issuance of shares of Stock upon exercise would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or the 

4

requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, the Award may not be exercised unless (i) a registration statement under the Securities Act shall at the time of exercise of the Award be in effect with
respect to the shares issuable upon exercise of the Award or (ii) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Award may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. THE PARTICIPANT IS CAUTIONED THAT THE AWARD MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, THE PARTICIPANT MAY NOT BE ABLE TO EXERCISE THE AWARD WHEN DESIRED EVEN THOUGH THE AWARD IS VESTED. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company's legal counsel to be necessary to the lawful issuance and sale of any shares subject to the Award shall relieve the Company of any liability with respect to the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to the exercise of the Award, the Company may require the Participant to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company.

		
	3.8
	Fractional Shares. The Company shall not be required to issue fractional 

shares upon the exercise of an Award.

		
	4.
	NONTRANSFERABILITY OF THE AW ARD.

During the lifetime of the Participant, an Award shall be exercisable only by the
 Participant or the Participant's guardian or legal representative.  Prior to the issuance of shares of Stock upon the exercise of an Award, the Award shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant's beneficiary, except transfer by
will or by the laws of descent and distribution. Following the death of the Participant, the Award, to the extent provided in Section 6, may be exercised by the Participant's legal representative or by any person empowered to do so under the deceased Participant's will or under the then applicable laws of descent and distribution.

5

		
	5.
	TERMINATION OF THE AWARD.

The Award shall terminate and may no longer be exercised after the first to occur of (a) the close of business on the Expiration Date, (b) the close of business on the last date for exercising the Award following termination of the Participant's Service as described in
Section 6, or (c) a Change in Control to the extent provided in Section 7.

		
	6.
	EFFECT OF TERMINATION OF SERVICE.

		
	6.1
	Award Exercisability.   The Award shall terminate  immediately upon the 

Participant' s termination of Service to the extent that it is then unvested and shall be exercisable after the Participant's termination  of Service to the extent it is then vested only during the applicable period as determined below and thereafter  shall terminate.

		
	(a)
	Disability.  If the Participant’s Service terminates because of the Disability of

 the Participant, the Award, to the extent unexercised and exercisable for Vested Rights on the date on which the Participant’s Service terminated, may be exercised by the Participant (or the Participant’s guardian or legal representative) at any time prior to the expiration of twelve (12) months after the date on which the Participant’s Service terminated, but in any event no later than the Expiration Date.

6

		
	(b)
	Death.  If the Participant's Service terminates because of the death of the 

Participant, the Award, to the extent unexercised and exercisable for Vested Rights on the date on which the Participant's Service terminated, may be exercised by the Participant's legal representative or other person who acquired the right to exercise the Award by reason of the Participant's death at any time prior to the expiration of twelve (12) months after the date on which the Participant's Service terminated, but in any event no later than the Expiration Date. The Participant's Service shall be deemed to have terminated on account of death if the Participant dies within three (3) months after the Participant's termination of Service.

		
	(c)
	Termination for Cause. Notwithstanding any other provision of this 

Agreement to the contrary, if the Participant's Service is terminated for Cause or if, following the Participant's termination of Service and during any period in which the Award otherwise would remain exercisable, the Participant engages in any act that would constitute Cause, the Award shall terminate in its entirety and cease to be exercisable immediately upon such termination of Service or act.

		
	(d)
	Other Termination of Service. If the Participant's Service terminates for any 

reason, except Disability, death or Cause, the Award, to the extent unexercised and exercisable for Vested Rights by the Participant on the date on which the Participant's Service terminated, may be exercised by the Participant at any time prior to the expiration of three (3) months after the date on which the Participant's Service terminated, but in any event no later than the Expiration Date.

		
	6.2
	Extension if Exercise Prevented by Law.  Notwithstanding the foregoing other 

than termination of the Participant's Service for Cause, if the exercise of the Award within the applicable time periods set forth in Section 6.1 is prevented by the provisions of Section 3.7, the Award shall remain exercisable until thirty (30) days after the date such exercise would no longer be prevented by such provisions, but in any event no later than the Expiration Date.

7

		
	7.
	EFFECT OF CHANGE IN CONTROL.

In the event of a Change in Control, except to the extent that the Committee determines 
to cash out the Award in accordance with Section 15.l(d) of the Plan, the surviving, continuing, successor, or purchasing entity or parent thereof, as the case may be (the "Acquiror"), may, without the consent of the Participant, assume or continue in full force and effect the Company's rights and obligations under all or any portion of the Award or substitute for all or any portion of the Award a substantially equivalent Award for rights with respect to the Acquiror's stock.  For purposes of this Section, if so determined by the Committee, in its discretion, the Award shall be deemed assumed if, following the Change in Control, the Award confers the right to receive, subject to the terms and conditions of the Plan and this Agreement, for each share of Stock subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, other securities or property or a combination thereof) to which a holder of a share of Stock on the effective date of the Change in Control was entitled; provided, however, that if such consideration is not solely common stock of the Acquiror, the Committee may, with the consent of the Acquiror, provide for the consideration to be received upon the exercise of the Award, for each share of Stock subject to the Award, to consist solely of common stock of the Acquiror equal in Fair Market Value to the per share consideration received by holders of Stock pursuant to the Change in Control.
