Exhibit 10.36

FORM OF DIRECTORS STOCK OPTION AGREEMENT AND GRANT

THIS STOCK OPTION AGREEMENT (this “Agreement”), dated as of the          day of             , (the “Grant Date”), by, between and among CRYOLIFE, INC., a Florida Corporation (the “Corporation”), and             , a member of the Board of Directors of the Corporation (a “Director”) and an individual residing in             (the “Optionee”).

WITNESSETH:

WHEREAS, the Corporation wishes to grant to the Optionee an option (the “Option”) to purchase the number of shares of Common Stock set forth in this Agreement and under the terms and conditions set forth herein including the provision that the Option is not an incentive stock option under Section 422 of the Internal Revenue Code of 1986, as amended (“Code”);

NOW THEREFORE, in consideration of the foregoing, the mutual promises and covenants contained herein and the mutual benefit to be derived therefrom and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby agree as follows:

1. Grant of Option: Subject to the terms and conditions set forth herein, the Corporation hereby grants to the Optionee the option to purchase, in the aggregate, up to              shares of the Common Stock (the “Shares”) which shall consist of authorized and unissued shares of the Common Stock or, at the option of the Corporation, treasury shares of Common Stock. The Option shall be deemed granted by the Corporation to the Optionee as of the Grant Date. This Option is not granted pursuant to the CryoLife, Inc. Amended and Restated Non-Employees Directors Plan (the “Plan”), but the terms of the Plan are incorporated herein by reference. The terms of the Plan shall govern this Option. Optionee acknowledges receipt of a copy of the Plan. The Optionee has received a Prospectus covering the Shares subject to this Option.

2. Option Price: The price of the Option shall be the last closing price of the Corporation’s Common Stock on the New York Stock Exchange on the day of the grant of the Option. The Option exercise price is the sum of $             per share (the “Option Exercise Price”).

3. Option Period: Subject to the limitations set forth in this Plan, an Option granted under the Plan shall vest and become exercisable on the Options’s Award Date. Subject to the limitations set forth in the Plan, the Option may be exercised at any time after its Award Date, provided that at the time of exercise all of the conditions set forth in the Plan have been met. Notwithstanding the foregoing, no Option may be exercised later than five years after the date of grant thereof.

4. Termination of Option: Except as herein otherwise stated, the Option, to the extent not previously exercised, shall terminate sixty (60) months following the Grant Date.

5. Cessation of Service: If a grantee leaves the Board of Directors for any reason, including without limitation resignation or death, such grantee’s Options shall remain in effect and exercisable, and shall expire as if the grantee had remained a Non-Employee Director of the Company. Upon the death of a Non-Employee Director, his or her Options shall be exercisable by his/her legal representatives or heirs, but in no event may the Options be exercised beyond the last date which they could have been exercised had the Non-Employee Director not died.

6. Delivery of Notice: The Optionee may exercise the Option only by delivering written notice to the Corporation of his intent to exercise the Option (the “Notice”). The Notice shall be delivered to the Corporation at its principal office at:

CRYOLIFE, INC.

1655 Roberts Blvd., N.W.

Kennesaw, Georgia 30144

or such other address as may be designated by the Corporation. The Notice shall specify the number of Shares to be purchased in accordance with this Agreement and shall include payment in full of the Option Price.

7. Payment: The Option Exercise Price shall be paid in cash in U.S. Dollars at the time the Option is exercised or in shares of Common Stock of the Company having an aggregate value equal to the Option Exercise Price. If the Option Exercise Price is paid by transfer of shares of Common Stock of the Corporation then the value of such shares will be determined by the last closing price of the Corporation’s Common Stock on the New York Stock Exchange prior to the exercise of the options. The Option Exercise Price may be paid by a combination of cash and Common Stock. Subject to approval by the Board, the phrase “shares of stock of the Company”, may include shares which the director is entitled to purchase by reason of a stock option grant, sometimes called “option shares”.

8. Delivery of Shares to Optioneee: Upon the Optionee’s proper exercise of the Option, the Corporation shall deliver to the Optionee one or more certificates evidencing the number of Shares purchased pursuant to the exercise of the Option and such Shares shall be fully paid and nonassessable.

9. Transferability: Except as otherwise provided in this paragraph 9, the Options granted under this Plan are not transferable other than as designated by the grantee by will or by the laws of the descent and distribution, and during the grantee’s life, may be exercised only by the grantee. However, the grantee may transfer the Option for no consideration to or for the benefit of the grantee’s Immediate Family (including, without limitation, to a trust for the benefit of the grantee’s Immediate Family or to a partnership or limited liability company for one or more members of the grantee’s

Immediate Family or to an IRA for the benefit of one or more members of his Immediate Family), subject to such limits as the Board may establish, and the transferee shall remain subject to all the terms and conditions applicable to such Option prior to such transfer. The foregoing right to transfer the Option shall apply to the right to consent to amendments to the grant agreement and shall also apply to the right to transfer ancillary rights associated with the Option. The term “Immediate Family” shall mean the grantee’s spouse, parents, children, stepchildren, adoptive relationships, sisters, brothers and grandchildren (and, for this purpose, shall also include the grantee).

10. Optionee Not a Shareholder: The Optionee shall not be deemed, by reason of this option agreement, for any purposes to be a shareholder of the Corporation with respect to any of the shares of the capital stock of the Corporation or with respect to any of the Shares, except to the extent that the Option has been exercised, in whole or in part, and a stock certificate representing Shares has been issued to the Optionee. Notwithstanding this provision, it is understood and agreed that the Corporation and the Optionee shall make any required disclosure of the “beneficial ownership” of Shares which may be received upon a future exercise of the Option.

11. No Restrictions on the Corporation: The grant of the Option shall not affect in any way the right or power of the Corporation or its shareholders to make or authorize any or all adjustments, recapitalizations, reorganizations, or any other changes in the Corporation’s capital structure or its business, or any merger or consolidation of the Corporation, or any issue of bonds, debentures, preferred or prior preference stock ahead of or affecting the Common Stock, or the rights thereof, or dissolution or liquidation of the Corporation, or any sale or transfer of all or any part of the assets or business of the Corporation, or any other corporate act or proceeding, whether of a similar character or otherwise.

12. Reclassification, Consolidation, or Merger: The number of Option Shares may be adjusted by the Board of Directors if certain events such as merger, reorganization, consolidation, recapitalization, stock dividends, stock splits, or other changes in the Company’s corporate structure affecting its Common Stock occur. No adjustments or substitution provided for in this Subsection, however, shall require the Corporation in any Agreement to sell a fractional share, and the total substitution or adjustment herein is and shall be limited accordingly.

The Optionee further agrees that he will not sell, assign, transfer or pledge the Option or any of the Shares purchased by him pursuant to the exercise of the Option, unless and until either (i) a registration statement

No Tax Advice: The Optionee understands that neither the Corporation nor any of its affiliates, has given any advice regarding the federal income tax consequences of (i) the Agreement, or (ii) the grant of the Option, or (iii) the acquisition of the Shares upon exercise of the Option. The Optionee acknowledges that he has been encouraged to seek independent advice regarding the grant and the exercise of the Option herein.

14. Legends: The Corporation shall have the discretion to require that the certificates representing the Shares shall bear such legends as are necessary to ensure the enforceability of the conditions and limitations set forth herein.

Any transfer of the option (if otherwise permitted hereunder, and once exercised, the Option Shares) will not be recognized by the Corporation unless such transfer is registered under the Act, the Georgia Act, and any other applicable state securities laws or effected pursuant to an exemption from such registration which may then be available. Any share certificates representing the Option Shares may be stamped with legends restricting transfer thereof in accordance with the Corporation’s policy with respect to unregistered shares of its Common Stock issued as a result of exercise of options. The Corporation may make a notation in its stock transfer records of the aforementioned restrictions on transfers and legends. Optionee recognizes and understands that the Option Shares may be restricted securities within the meaning of Rule 144 promulgated under the Act; that the exemption from registration under Rule 144 may not be available under certain circumstances and that Optionee’s opportunity to utilize such Rule 144 to sell the Option Shares may be limited or denied. The Corporation shall be under no obligation to maintain or promote a public trading market for the class of shares for which the option is granted or to make provision for adequate information concerning the Corporation to be available to the public as contemplated under Rule 144. The Corporation will be under no obligation to

recognize any transfer or sale of any Option Shares unless the terms and conditions of Rule 144 are complied with by the Optionee. By acceptance hereof, Optionee agrees that no permitted disposition of this option or any Option Shares shall be made unless and until (i) there is then in effect a registration statement under the Act, the Georgia Act, and applicable state securities laws covering such proposed disposition and such disposition is made in accordance with such registration statement, or (ii) Optionee shall have notified the Corporation of a proposed disposition and shall have furnished to the Corporation a detailed statement of the circumstances surrounding such disposition, together with an opinion of counsel acceptable in form and substance to the Corporation that such disposition will not require registration of the shares so disposed under the Act, the Georgia Act, and any applicable state securities laws. The Corporation shall be under no obligation to permit such transfer or disposition on its stock transfer books unless counsel for the Corporation shall concur as to such matters.

25. Applicable Taxes: No later than the date as of which an amount first becomes includable in the gross income of the Optionee for Federal income tax purposes with respect to the exercise of the Option, the Optionee shall pay to the Corporation, or make arrangements satisfactory to the Corporation regarding the payment of any Federal, state, or local taxes of any kind required by law to be withheld with respect to such amount. The obligations of the Corporation under this Agreement shall be conditional upon such payment or arrangements and the Corporation 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 Optionee.

IN WITNESS WHEREOF, the Corporation has caused this instrument to be executed by its duly authorized officers and the Optionee has executed this Agreement as of the date and year first above written.
