Xx. Xxx Xxxxxx

Dear Xxx:

Pursuant to our discussions regarding your employment with J. Crew Group, Inc. (the “Parent”) and its operating subsidiaries (collectively with the Parent, the “Company”), we thought it would be useful to lay out the terms and conditions of our agreement in this letter agreement (the “Agreement”) for all parties to sign.

1. Employment.

(a) The Company hereby agrees to employ you during the “Employment Period” (as defined below) as Chief Financial Officer (principal financial officer and principal accounting officer), and you hereby agree to serve the Company in such capacity. You shall report to the Chief Executive Officer of the Company.

(b) During the Employment Period, you shall devote your full business time and energy, attention, skills and ability to the performance of your duties and responsibilities hereunder and shall faithfully and diligently endeavor to promote the business and best interests of the Company. Accordingly, you may not, directly or indirectly, without the prior written consent of the Company, operate, participate in the management, operations or control of, or act as an employee, officer, consultant, agent or representative of, any type of business or service (other than as an employee of the Company), provided that it shall not be a violation of the foregoing for you to (i) act or serve as a director, trustee or committee member of any civic or charitable organization, and (ii) manage your personal, financial and legal affairs, so long as such activities (described in clauses (i) or (ii)) do not interfere with the performance of your duties and responsibilities to the Company as provided hereunder.

2. Employment Period.

(a) The “Employment Period” shall begin on September 7, 2005 (the “Effective Date”) and shall terminate (“Termination Date”) upon the earliest to occur of (i) the third anniversary of the Effective Date (the “Scheduled Termination Date”), (ii) your death or Disability (as defined below), (iii) voluntary termination of employment by you without Good Reason (as defined below) on at least two months prior notice, (iv) voluntary termination of employment by you for Good Reason in accordance with the procedure outlined in Section 2(e) below, (v) termination of employment by the Company without Cause (as defined below) or (vi) termination of employment by the Company for Cause. The Scheduled Termination Date shall be extended for successive one year periods beginning on the third anniversary of the Effective Date and on each anniversary thereafter, unless either the Company or you notifies the other in

writing at least four months prior to the applicable Scheduled Termination Date of its intention not to extend the Scheduled Termination Date further in which case the Employment Period shall terminate on such Scheduled Termination Date.

(b) Upon termination of the Employment Period for any reason, you shall be entitled to any earned but unpaid Base Salary (as defined below) as of the Termination Date. If the Company terminates the Employment Period without Cause or you terminate the Employment Period for Good Reason, you will be entitled to the following severance benefits (the “Severance Benefits”): (i) continuation of your Base Salary as in effect immediately prior to such termination (your “Ending Base Salary”, and such continuation of your Ending Base Salary being referred to herein as the “Continuation Severance Payment”) and medical benefits which may be provided by the Company reimbursing payment of COBRA premiums if any (“Continuation Medical Benefit”) for a period of one (1) year (the “Severance Period”) after the Termination Date and (ii) a lump sum amount, equal to the product of (x) the Annual Bonus, if any, that you would have earned (based only upon the objective bonus criteria) in the fiscal year which includes the Termination Date had your employment not been terminated and (y) a fraction, the numerator of which is the number of days in the fiscal year that includes the Termination Date through the Termination Date and the denominator of which is 365, payable when bonuses are generally paid to the employees of the Company (“Pro-Rata Bonus”); provided that the Severance Benefits are subject to and conditioned upon your execution of a valid general release and waiver in a form reasonably satisfactory to the Company waiving all claims that you may have against the Company, its successors, assigns, affiliates, employees, officers and directors and your compliance with the provisions set forth in Section 4 hereof. Notwithstanding anything herein to the contrary, your right to receive the Continuation Severance Payment during the Severance Period shall terminate effective immediately upon the date that you become employed by a new employer or otherwise begin providing services for an entity as a consultant or otherwise (“New Employment”); provided that if the cash compensation you receive pursuant to such New Employment, including without limitation guaranteed bonus payments relating to the Severance Period whether or not paid during the Severance Period, (“New Compensation”) is less than your Ending Base Salary, the Company will continue to pay you an incremental amount during the remaining Severance Period such that the New Compensation payments you receive together with such incremental amount will equal your Ending Base Salary on an annualized basis and your right to receive the Continuation Medical Benefit shall cease immediately upon your being eligible for coverage under another group health plan. You shall immediately notify the Company upon obtaining New Employment and provide all information regarding medical benefits coverage reasonably requested by the Company. The Company shall have no additional obligations under this Agreement, including under any severance or termination pay plan, and your rights under any benefit plan of the Company to vested benefits or welfare benefits will be determined pursuant to the terms of the applicable plan. Notwithstanding the foregoing, in the event the payments or benefits under this Section 2(b) would result in the imposition of a tax under Section 409A of the Internal Revenue Code of 1986, as amended, then such payments or benefits will be paid or provided at such time when such payments or benefits would not be subject to such tax.

2

(c) For purposes of this Agreement, the term “Cause” shall mean (i) the indictment for a felony or any crime involving moral turpitude or being charged or sanctioned by a federal or state government or governmental authority or agency with violations of federal or state securities laws in any judicial or administrative process or proceeding, or having been found by any court or governmental authority or agency to have committed any such violation, (ii) willful misconduct or gross negligence in connection with the performance of your duties as an employee of the Company, (iii) a willful and material breach of this Agreement, including without limitation, your failure to perform your duties and responsibilities hereunder, after you have been given written notice specifying such breach and at least thirty (30) days to cure such breach, to the extent reasonably susceptible to cure, (iv) a fraudulent act or omission by you adverse to the reputation of the Company or any affiliate, (v) the willful disclosure by you of any Confidential Information (as defined below) to persons not authorized to know same, and (vi) your violation of or failure to comply with (A) any Company policy, including, without limitation, the Code of Ethics and Business Practices, or (B) any legal or regulatory obligations or requirements, including, without limitation, failure to provide any certifications as may be required by law, provided that with respect to this Section 2(c)(vi), you shall be given thirty (30) days to cure such violation to the extent such violation is reasonably susceptible to cure. If subsequent to the termination of your employment, it is discovered that your employment could have been terminated for Cause pursuant to sections (i) or (iv) of this Section 2(c), your employment shall, at the election of the Company, in its sole discretion, be deemed to have been terminated for Cause in which event the Company shall be entitled to immediately cease providing any Severance Benefits to you or on your behalf and recover any payments previously made to you or on your behalf in the form of Severance Benefits. For purposes of this provision, no act or omission on your part shall be considered “willful” unless it is done, or omitted to be done, by you in bad faith or without reasonable belief that your action or omission was in the best interests of the Company. Any act, or failure to act, based upon authority given pursuant to a resolution duly adopted by the Board of Directors of the Parent (the “Board”) shall be conclusively presumed to be done, or omitted to be done, by you in good faith and in the best interests of the Company.

(d) For purposes of this Agreement, the term “Disability” shall mean your incapacity due to physical or mental illness or injury, which results in your being unable to perform your duties hereunder for a period of ninety (90) consecutive working days, and within thirty (30) days after the Company notifies you that your employment is being terminated for Disability, you shall not have returned to the performance of your duties on a full-time basis.

(e) For purposes of this Agreement, the term “Good Reason” shall mean (i) any action by the Company that results in a material and continuing diminution in your position, authority, duties or responsibilities, including without limitation a change in your title from Chief Financial Officer or a change such that you no longer report directly to the Chief Executive Officer; (ii) a reduction by the Company in your Base Salary or Annual Bonus opportunity as in effect on the Effective Date or as the same may be increased from time to time; or (iii) a relocation of your principal place of employment to more than fifty (50) miles from your

3

principal place of employment, in each case without your written consent. Termination of your employment for “Good Reason” shall not be effective until you deliver to the Board a written notice specifically identifying the conduct of the Company which you believe constitutes “Good Reason” in accordance with this Section 2(e) and you provide the Board at least thirty (30) days to remedy such conduct.

3. Compensation and Benefits.

(a) Base Salary. During the Employment Period, your annual base salary shall be $475,000 (“Base Salary”) and shall be paid pursuant to regular Company payroll practices for the senior executives of the Company. The Base Salary will be reviewed annually by the Company.

(b) Annual Bonus. In addition to the Base Salary, in each fiscal year during the Employment Period, you will have the opportunity to earn an annual bonus (“Annual Bonus”) at the following percentages of your Base Salary if both the Company achieves certain performance objectives (which will be determined by the Company for each such fiscal year in accordance with the Company’s bonus plan) and you achieve your performance goals established by the Company: target bonus of 50% up to a maximum bonus of 100% of Base Salary. Notwithstanding the foregoing, your Annual Bonus for the fiscal year beginning January 30, 2005 will be $250,000 (the “FY ’05 Guaranteed Bonus”) regardless of the achievement or non-achievement of performance objectives for such fiscal year. Any Annual Bonus (including the FY ‘05 Guaranteed Bonus, if applicable) will be paid only if you are actively employed with the Company and not in breach of this Agreement on the date of actual payment, except for any Pro-Rata Bonus payable pursuant to Section 2(b) hereof.

(c) Transition Support Payment. No later than thirty (30) days after the Effective Date, the Company will pay you a transition support payment (“Transition Support Payment”) of $165,000 as consideration for entering into this Agreement, provided that you will be required to immediately pay back the pro-rata portion of the Transition Support Payment in the event you voluntarily terminate your employment hereunder other than for Good Reason or your employment is terminated by the Company for Cause within one (1) year after the Effective Date. The pro-ration shall be determined on the basis of the number of full months having elapsed from the Effective Date to the Termination Date, divided by twelve. To the extent that you fail to pay back any portion of the Transition Support Payment as provided herein, the Company shall have the right to offset any other payments provided hereunder or otherwise owed to you in respect of such amount.

(d) Initial Stock Options. As soon as reasonably practicable after the Effective Date, and subject to the approval of the Board or a Committee thereof, the Company will cause the Parent to grant you a non-qualified stock option (the “Initial Option”) to purchase 50,000 shares of common stock of the Parent (the “Common Stock”) at an exercise price per share equal to the fair market value of the Common Stock on the date of grant. Twenty-five (25%) percent of the

4
