Exhibit 10.37 NONSTATUTORY STOCK OPTION AGREEMENT (cliff vesting, performance-based acceleration) Pursuant to the Grant Notice and this Nonstatutory Stock Option Agreement, the Company has granted you an option to purchase the number of shares of Common Stock indicated in the Grant Notice at the exercise price indicated in the Grant Notice. Shares issued upon your exercise of your option are hereinafter referred to as "Option Shares." Your option is granted in connection with and in furtherance of the Company's compensatory benefit plan for the Company's employees (including officers), directors or consultants, and is intended to comply with the provisions of Rule 701 promulgated by the Securities and Exchange Commission under the Securities Act of 1933, as amended (the "Securities Act"). Defined terms not explicitly defined in this Stock Option Agreement but defined in the Plan shall have the same definitions as in the Plan. The details of your option are as follows: 1. Vesting. Subject to the limitations contained herein, your option will vest as provided in the Grant Notice. 2. Method of Payment. (a) Payment Options. Payment of the exercise price by cash or check is due in full upon exercise of all or any part of your option, provided that you may elect, to the extent permitted by applicable law and the Grant Notice, to make payment of the exercise price under one of the following alternatives: (i) Payment pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board which, prior to the issuance of Option Shares, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds; (ii) Delivery of shares of any class or series of the Company's capital stock, the fair market value of which (as determined by the board of directors of the Company in its sole discretion) is equal to the option exercise price; or (iii) Payment by a combination of the above methods. 3. Whole Shares. Your option may only be exercised for whole shares. 4. Securities Law Compliance. Notwithstanding anything to the contrary contained herein, your option may not be exercised unless the shares issuable upon exercise of your option are then registered under the Securities Act or, if such shares are not then so registered, the Company has determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act. 1 5. Term. The term of your option commences on the date of grant and expires upon the earliest of: (i) the Expiration Date indicated in the Grant Notice; and (ii) the violation by you of any provision of this Agreement. 6. Exercise. (a) You may exercise the your option during its term (to the extent vested) by delivering a notice of exercise (in a form designated by the Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with such additional documents as the Company may then require. (b) By exercising your option you agree that the Company (or a representative of the underwriters) may, in connection with the first underwritten registered public offering of any securities of the Company under the Securities Act, require that you not sell or otherwise transfer or dispose of any Option Shares or other securities of the Company during such period (not to exceed one hundred eighty (180) days) following the effective date of the registration statement of the Company filed under the Securities Act as may be requested by the Company or the representative of the underwriters. You further agree that the Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such period. 7. Transferability. Your option is not transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your death, shall thereafter be entitled to exercise your option. 8. Right of First Refusal. The Company shall have a right of first refusal, as set forth below, with respect to the Option Shares. Except for Permitted Transfers (as defined below), no Option Shares may be transferred unless (a) the holder delivers to the Company written notice of his/her intent to transfer all or any part of such shares (the "Offered Shares"), including the name and address of the proposed transferee and the proposed terms and conditions of such transfer (the "Notice of Intent to Sell"), and (b) within thirty (30) days following its receipt of the Notice of Intent to Sell the Company does not deliver to the holder written notice of its intent to exercise its right of first refusal and purchase the Offered Shares on the terms set forth in the Notice of Intent to Sell. The Company's right of first refusal must be exercised as to all the Offered Shares unless the holder consents to exercise for less than all the Offered Shares. The purchase of the Offered Shares following exercise must be completed within sixty (60) days of the Company's receipt of the Notice of Intent to Sell or such longer period of time as has been offered by the person to whom you intend to transfer the Offered Shares. "Permitted Transfer" means a transfer to a member of your immediate family or to a trust for the benefit of you and/or one or more members of your immediate family, provided that each such transferee shall have 2 executed and delivered to the Company a written acknowledgment that such Option Shares remain subject to the provisions of this Agreement, including the Company's right of first refusal hereunder. This Section 8 shall terminate and be of no further force and effect upon the closing of the first underwritten public offering of the Company's equity securities under the Securities Act. 9. Taxation; Tax Withholding Requirements. You understand and acknowledge that upon exercise of your option you will recognize for income tax purposes an amount of ordinary income equal to the excess, if any, of the fair market value of the shares of the Common Stock received over the exercise price for such shares. Any amounts required by any then applicable tax law to be withheld by the Company from the compensation you are deemed to have received upon any exercise of your option or portion thereof shall be satisfied, at election, either by having the Company withhold shares, or by delivery of cash or shares of the Common Stock having a value equal to the amount required to be withheld. 10. Option Not a Service Contract. Your option is not an employment contract and nothing in your option shall be deemed to create in any way whatsoever any obligation on your part to continue or resume being in the employ of the Company, or of the Company to continue or resume your employment with the Company. In addition, nothing in your option shall obligate the Company, its shareholders, board of directors, officers or employees to continue or resume any relationship which you might have as a director or consultant for the Company. 11. Notices. Any notices provided for in your option or in the Plan shall be given in writing and shall be deemed effectively given upon receipt or, in the case of notices delivered by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address you provided to the Company. 12. Governing Plan Document. Your option is subject to all the provisions of the Plan, the provisions of which are hereby made a part of your option, including without limitation the provisions of the Plan relating to option provisions, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflict between the provisions of your option and those of the Plan, the provisions of the Plan shall control. 3 VISTACARE, INC.
