Exhibit 10.1

AFFIRMATIVE INSURANCE HOLDINGS, INC.

AMENDED AND RESTATED 2004 STOCK INCENTIVE PLAN

as amended

STOCK OPTION AGREEMENT

This Stock Option Agreement (the “Agreement”) is made and entered into as of the date of grant set forth below (the “Date of Grant”) by and between Affirmative Insurance Holdings, Inc., a Delaware corporation (the “Company”), and the participant named below (the “Participant”). Capitalized terms not defined herein shall have the meaning ascribed to them in the Company’s Amended and Restated 2004 Stock Incentive Plan, as amended (the “Plan”).

Page 1

1. Grant of Option. The Company hereby grants to Participant an option (this “Option”) to purchase the total number of shares of Common Stock of the Company set forth above as Total Option Shares (the “Shares”) at the Exercise Price Per Share set forth above (the “Exercise Price”), subject to all of the terms and conditions of this Agreement and the Plan. If designated as an Incentive Stock Option above, the Option is intended to qualify as an “incentive stock option” (an “ISO”) within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), although the Company makes no representation or guarantee that such Option will qualify as an ISO.

2. Exercise Period; Vesting.

2.1. Exercise Period. Unless expired as provided in Section 3 of this Agreement, this Option may be exercised from time to time after the Date of Grant set forth above (the “Date of Grant”) to the extent the Option has vested in accordance with the vesting schedule in Subsection 2.2.

2.2. Vesting. Provided Participant’s employment pursuant to his employment agreement has not terminated prior to such vesting dates, the Option will become vested and exercisable according to the Vesting Schedule. If application of the vesting percentage causes a fractional share, such share shall be rounded down to the nearest whole share for each vesting period except for the last period in such vesting period, at the end of which last period this Option shall become exercisable for the full remainder of the Shares. The Shares issued upon exercise of the Option will be subject to the restrictions on transfer set forth in Sections 8 and 9 below.

3. Expiration. The Option shall expire on the Expiration Date set forth above or earlier as provided in Section 4 below or, if applicable, pursuant to Section 11 of the Plan.

4. Termination of Continuous Service.

4.1. Termination for Any Reason Except Death, Disability or Cause. Unless otherwise provided in an employment agreement the terms of which have been approved by the Administrator, if Participant’s Continuous Service is terminated for any reason, except death, disability or for Cause, the Option, to the extent (and only to the extent) that it would have been exercisable by Participant on the date of termination, may be exercised by Participant no later than three (3) months after the date of termination, but in any event no later than the Expiration Date.

4.2. Termination Because of Death or Disability. If Participant’s Continuous Service is terminated because of death or disability of Participant, the Option, to the extent that it would have been exercisable by Participant on the date of termination, may be exercised by Participant (or Participant’s legal representative) no later than twelve (12) months after the date of termination, but in any event no later than the Expiration Date. If permitted by this Agreement, any exercise beyond twelve (12) months after the date of termination when the termination is for Participant’s disability is deemed to be a Nonstatutory Stock Option (an “NSO”) and not an ISO.

Page 2

4.3. Termination for Cause. If Participant’s Continuous Service is terminated for Cause, then the Option will expire on the Participant’s date of termination.

4.4. No Obligation to Employ. Nothing in the Plan or this Agreement shall confer on Participant any right to continue in the employ of, or other relationship with, the Company or any Affiliate, or limit in any way the right of the Company or any Affiliate to terminate Participant’s employment or other relationship at any time, with or without Cause.

5. Manner of Exercise.

5.1. Stock Option Exercise Agreement. To exercise this Option, Participant (or in the case of exercise after Participant’s death or incapacity, Participant’s executor, administrator, heir or legatee, as the case may be) must deliver to the Company an executed stock option exercise agreement in the form attached hereto as Exhibit A, or in such other form as may be approved by the Administrator from time to time (the “Exercise Agreement”), which shall set forth, inter alia, (a) Participant’s election to exercise the Option, (b) the number of Shares being purchased, (c) any restrictions imposed on the Shares and (d) any representations, warranties, and agreements regarding Participant’s investment intent and access to information as may be required by the Company to comply with applicable securities laws. If someone other than Participant exercises the Option, then such person must submit documentation reasonably acceptable to the Company verifying that such person has the legal right to exercise the Option.

5.2. Limitations on Exercise. The Option may not be exercised unless such exercise is in compliance with all applicable federal and state securities laws, as they are in effect on the date of exercise. The Option may not be exercised for fewer than one (1) Share unless it is exercised as to all Shares as to which the Option is then exercisable.

5.3. Payment. The Exercise Agreement shall be accompanied by full payment of the Exercise Price for the shares being purchased in cash (by certified check or wire transfer), or where permitted by law and upon written approval by the Administrator:

(a) by surrender of shares of the Company’s Common Stock that (i) either (1) have been owned by Participant for more than six (6) months and have been paid for within the meaning of SEC Rule 144 (and, if such shares were purchased from the Company by use of promissory note, such note has been fully paid with respect to such shares); or (2) were obtained by Participant in the open public market; and (ii) are clear of all liens, claims, encumbrances or security interests;

(b) provided that a Listing Date has occurred: (i) through a “same day sale” commitment from Participant and a broker-dealer that is a member of the National Association of Securities Dealers (an “NASD Dealer”) whereby Participant irrevocably elects to exercise the Option and to sell a portion of the Shares so purchased sufficient to pay for the total Exercise Price and whereby the NASD Dealer irrevocably commits upon receipt of such Shares to forward the total Exercise Price directly to the Company, or (ii) through a “margin” commitment from Participant and an NASD Dealer whereby Participant irrevocably elects to exercise the Option and to pledge the Shares so purchased to the NASD Dealer in a margin account as security for a loan from NASD Dealer in the amount of the total Exercise Price, and

Page 3

whereby the NASD Dealer irrevocably commits upon receipt of such Shares to forward the total Exercise Price directly to the Company; provided, however, a cashless exercise by a Director or executive officer that involves or may involve a direct or indirect extension of credit or arrangement of an extension of credit by the Company or an Affiliate in violation of Section 402(a) of the Sarbanes-Oxley Act (codified as Section 13(k) of the Securities Exchange Act of 1934, 15 U.S.C. § 78m(k)) shall be prohibited;

(c) by any other form of legal consideration that may be acceptable to the Administrator; or

(d) by any combination of the foregoing.

5.4. Tax Withholding. Prior to the issuance of the Shares upon exercise of the Option, Participant must pay or provide for any applicable federal, state and local withholding obligations of the Company.

5.5. Issuance of Shares. Provided that the Exercise Agreement and payment are in form and substance satisfactory to counsel for the Company, the Company shall issue the Shares registered in the name of Participant, Participant’s authorized assignee, or Participant’s legal representative, and shall deliver certificates representing the Shares with the appropriate legends affixed thereto.

6. Notice of Disqualifying Disposition of ISO Shares. If the Option is an ISO, and if Participant sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (a) the date two (2) years after the Date of Grant, and (b) the date one (1) year after transfer of such Shares to Participant upon exercise of the Option, Participant shall immediately notify the Company in writing of such disposition. Participant agrees that Participant may be subject to income tax withholding by the Company on the compensation income recognized by Participant from the early disposition by payment in cash or out of the current wages or other compensation payable to Participant.

7. Compliance with Laws and Regulations. The exercise of the Option and the issuance and transfer of Shares shall be subject to compliance by the Company and Participant with all applicable requirements of federal and state securities laws and with all applicable requirements of any stock exchange on which the Company’s Common Stock may be listed at the time of such issuance or transfer. Participant understands that the Company is under no obligation to register or qualify the Shares with the SEC, any state securities commission or any stock exchange to effect such compliance.

8. Nontransferability of Option. If the Option is an ISO, the Option may not be transferred in any manner other than by will or by the laws of descent and distribution and may be exercised during the lifetime of Participant only by Participant or in the event of Participant’s incapacity, by Participant’s legal representative. The terms of the Option shall be binding upon the executors, administrators, successors and assigns of Participant. If the Option is not an ISO, upon written approval by the Administrator, it may be transferred by gift or domestic relations order to a member of the Participant’s immediate family (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 Participant’s household (other than a tenant or employee), a trust in which these persons have more than 75% of the beneficial interest, a foundation in which these persons (or the Participant) control the management of assets, and any other entity in which these persons (or the Participant) own more than 75% of the voting interests.

9. Privileges of Stock Ownership. Participant shall not have any of the rights of a stockholder with respect to any Shares until the Shares are issued to Participant.

10. General.

10.1. Interpretation. Any dispute regarding the interpretation of this Agreement shall be submitted by Participant or the Company to the Administrator for review. The resolution of such a dispute by the Administrator shall be final and binding on the Company and Participant.

10.2. Entire Agreement. The Plan and Participant’s employment agreement are incorporated herein by reference. This Agreement and the Plan constitute the entire agreement of the parties and supercede all prior undertakings and agreements with respect to the subject matter hereof. If any inconsistency should exit between the nondiscretionary terms and conditions of this Agreement and the Plan, the Plan shall govern and control.

10.3. Notices. Any notice required to be given or delivered to the Company under the terms of this Agreement shall be in writing and addressed to the Corporate Secretary of the Company at its principal corporate offices. Any notice required to be given or delivered to Participant shall be in writing and addressed to Participant at the address indicated above or to such other address as such party may designate in writing from time to time to the Company.

This Agreement shall be binding upon and inure to the benefit of the successors and assigns of the Company.

10.5. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without giving effect to its conflict of law principles. If any provision of this Agreement is determined by a court of law to be illegal or unenforceable, then such provision will be enforced to the maximum extent possible and the other provisions will remain fully effective and enforceable.

11. Acceptance. Participant hereby acknowledges receipt of a copy of the Plan and this Agreement. Participant has read and understands the terms and provisions thereof, and accepts the Option subject to all the terms and conditions of the Plan and this Agreement.
