RECITALS

The Orthovita, Inc. 2007 Omnibus Equity Compensation Plan (the “Plan”) provides for the grant of options to purchase shares of common stock of the Company. The Company has decided to make a stock option grant as an inducement for the Grantee to promote the best interests of the Company and its shareholders.

NOW, THEREFORE, the parties to this Agreement, intending to be legally bound hereby, agree as follows:

1. Grant of Option; Vesting. Subject to the terms and conditions set forth in this Agreement and in the Plan, the Company hereby grants to the Grantee a nonqualified stock option (the “Option”) to purchase                     shares of common stock of the Company (“Shares”) at an exercise price of $                     per Share. [The Option shall be fully vested on the Date of Grant./This Option shall vest and be exercisable as follows: [VESTING SCHEDULE HERE].

2. Term of Option.

(a) The Option shall have a term of ten years from the Date of Grant and shall terminate at the expiration of that period on                     , 20    , unless it is terminated at an earlier date pursuant to the provisions of this Agreement or the Plan.

(b) The Option shall automatically terminate upon the happening of the first of the following events:

(i) The expiration of the one-year period after the Grantee’s death, liquidation or dissolution.

(ii) The finding by the Company after full consideration of the facts presented on behalf of both the Company and Grantee that the Grantee has breached any contract with the Company, or has been engaged in disloyalty to the Company or an affiliate thereof, including, without limitation, fraud, embezzlement, theft, commission of a felony or proven dishonesty in the course of his service, or has disclosed trade secrets or confidential information of the Company or an affiliate thereof. In such event, in addition to immediate termination of the Option, the Grantee shall automatically forfeit all Shares for which the Company has not yet delivered the share certificates upon refund by the Company of the Option exercise price. Notwithstanding anything herein to the contrary, the Company may withhold delivery of share certificates pending the resolution of any inquiry that could lead to a finding resulting in a forfeiture.

Notwithstanding the foregoing, in no event may the Option be exercised after the date that is immediately before the tenth anniversary of the Date of Grant.

3. Exercise Procedures.

(a) Subject to the provisions of Paragraph 2 above, the Grantee may exercise part or all of the exercisable Option by giving the Company written notice of intent to exercise in the manner provided in this Agreement, specifying the number of Shares as to which the Option is to be exercised and the method of payment. Payment of the exercise price shall be made in accordance with procedures established by the Board of Directors of the Company (the “Board”) or Compensation Committee of the Board (the “Committee”) from time to time based on type of payment being made but, in any event, prior to issuance of the Shares. The Grantee shall pay the exercise price (i) in cash, (ii) if permitted by the Board or the Committee, by delivering Shares owned by the Grantee and having a fair market value on the date of exercise equal to the exercise price, or by attestation (on a form prescribed by the Committee) to ownership of Shares having a fair market value on the date of exercise equal to the exercise price, (iii) by payment through a broker in accordance with procedures permitted by Regulation T of the Federal Reserve Board or (iv) by such other method as the Committee may approve, to the extent permitted by applicable law, or (v) through any combination of the foregoing. The Committee may impose from time to time such limitations as it deems appropriate on the use of Shares of the Company to exercise the Option.

(b) The obligation of the Company to deliver Shares upon exercise of the Option shall be subject to all applicable laws, rules, and regulations and such approvals by governmental agencies as may be deemed appropriate by the Committee, including such actions as Company counsel shall deem necessary or appropriate to comply with relevant securities laws and regulations. The Company may require that the Grantee (or other person exercising the Option after the Grantee’s death) represent that the Grantee is purchasing Shares for the Grantee’s own account and not with a view to or for sale in connection with any distribution of the Shares, or such other representation as the Committee deems appropriate.

(c) All obligations of the Company under this Agreement shall be subject to the rights of the Company as set forth in the Plan to withhold amounts required to be withheld for any taxes, if applicable. Subject to Committee approval, the Grantee may elect to satisfy any tax withholding obligation of the Company with respect to the Option by having Shares withheld up to an amount that does not exceed the minimum applicable withholding tax rate for federal (including FICA), state and local tax liabilities subject to prior approval by the Committee.

4. Change of Control. The provisions of the Plan applicable to a Change of Control shall apply to the Option, and, in the event of a Change of Control, the Committee may take such actions as it deems appropriate pursuant to the Plan.

As a condition to each issuance of Shares from time to time hereunder, Grantee may be required to make the representation set forth in this Section 6(b) to ensure compliance with federal securities laws.

7. No Employment or Other Rights.
