Exhibit 10.35

Dear Jeff:

Somaxon Pharmaceuticals, Inc. (“Somaxon”) desires to obtain your services as a consultant during the term of this agreement. You agree to provide such services in accordance with the following terms and conditions.

At times agreeable to you and as requested by Somaxon, you will make available your services and undertake consulting for a period commencing on the date first listed above (the “Effective Date”) and expiring on June 30, 2013, subject to earlier termination or renewal as provided in Section 4 (the “Term”). No services shall be performed by you prior to the written request by Somaxon to perform such services. The services shall include, but not be limited to, information, advice and assistance concerning matters that are within the scope of your knowledge and expertise as mutually agreed to between you and Somaxon.

As compensation for your services, Somaxon shall pay you $200.00 per hour. Total hours will be limited initially to up to ten (10) pre-authorized hours per month, unless additional hours are further authorized by Somaxon in writing.

During the Term, all of your unexercised stock options, restricted stock units and such other awards (collectively, the “Stock Awards”) granted pursuant to the Company’s 2004 Equity Incentive Award Plan or 2005 Equity Incentive Award Plan (the “Plans”) and related Stock Award agreements shall continue to vest and be exercisable, if applicable, pursuant to the terms of the Plans and related Stock Award agreements pursuant to which they were granted. Following the expiration of the Term, the vested Stock Awards shall be exercisable by you in accordance with the terms of the Plans, related Stock Award agreements pursuant to which they were granted and the Separation Agreement between you and Somaxon dated as of October 1, 2011. There shall be no break in service as a result of your conversion from an employee to an independent contractor for purposes of your Stock Awards.

In addition, you shall be reimbursed for air travel (economy class), and all reasonable living expenses, including but not limited to car rental, meals and lodging incurred by you when associated with the rendering of your services at locations away from the San Diego area, subject to the prior written approval of Somaxon. You shall be solely responsible for all other expenses incurred in the performance of your services under this Agreement.

Somaxon shall make all payments to you hereunder within thirty (30) days of receipt of an invoice from you itemizing your hours spent providing services hereunder and permitted expenses, including receipts for incidental expenses in excess of $25.00.

All payments, including reimbursements for actual expenditures, shall be included in your gross income as compensation for services rendered and accordingly reported on your IRS Form 1099.

You shall be responsible for payment of all taxes, including Social Security taxes, on income earned under this Agreement as none will be withheld by Somaxon.

Your invoices shall be e-mailed to Somaxon at accountspayable@somaxon.com.

It is agreed that you are to have complete freedom of action as to the details, methods, and means of performing services hereunder. It is further understood that you are retained and have contracted with Somaxon only for the purposes and to the extent set forth in this Agreement, and your relation to Somaxon shall, during the period of your retainer and service, be that of an independent contractor, and you shall be free to dispose of such portion of your entire time, energy, and skill as you are not obligated to devote to Somaxon in such manner you see fit and to such persons, firms, or corporations as you deem advisable, so long as same does not create a conflict of interest between Somaxon and such other persons, firms, or corporations.

You shall not be considered under the provisions of this Agreement or otherwise as having status as an employee of Somaxon, nor shall you be entitled hereafter to participate in any plans, arrangements, or distributions by Somaxon relating to any pension, deferred compensation, stock bonus, stock option, hospitalization, insurance, or other benefits extended to its employees since you are performing the services as an independent contractor.

This Agreement becomes effective as of the Effective Date and will continue in effect for the Term, unless otherwise extended by the mutual agreement of the parties. It is provided, however, that either you or Somaxon may immediately terminate this Agreement at any time during the Term. Upon any notice of termination, you agree to discontinue any services performed for Somaxon under this agreement, unless otherwise agreed to between you and Somaxon.

Termination of this Agreement shall not affect (i) Somaxon’s obligation to pay for services previously rendered by you or expenses reasonably incurred by you for which you are entitled to reimbursement under Section 2 of this Agreement, or (ii) your obligations to Somaxon under Sections 5, 6 and the first paragraph of Section 10 of this Agreement

In the event a court or governmental agency legally compels you to disclose Confidential Information, you shall promptly inform Somaxon of the compelled disclosure, so that Somaxon may seek a protective order or other remedy or waive compliance with this Agreement, or both. In any event, you shall limit any compelled disclosure of Confidential Information to that legally required.

In addition, you agree to execute, when requested, patent, copyright or similar applications and assignments to Somaxon and any other lawful documents deemed necessary by Somaxon to carry out the purposes of this Agreement with respect thereto.

All right, title and interest of every kind and nature whatsoever in and to any Intellectual Property made, discussed, developed, secured, obtained or learned by you during the term of this Agreement, or the 60-day period immediately following termination of this Agreement, are hereby assigned to Somaxon, and shall be the sole and exclusive property of Somaxon for any purposes or uses whatsoever, and shall be disclosed promptly by you to Somaxon. All copyrightable material shall constitute works for hire.

You agree that, during the Term of this Agreement, you will not, without Somaxon’s express written consent, engage in any employment or activity (whether as a consultant, advisor or otherwise) in any business competitive with Somaxon’s current business.

It is agreed that your rendering of services under this Agreement shall in no way conflict or interfere with your existing job responsibilities.

If you breach or threaten to commit a breach of any of the provisions of Sections 5 or 6 or the first paragraph of Section 10 below (collectively, the “Restrictive Covenants”), Somaxon shall have the right and remedy to have the Restrictive Covenants specifically enforced by any court of competent jurisdiction (without the need to post bond or other security), it being agreed that any breach or threatened breach of the Restrictive Covenants would cause irreparable injury to Somaxon and that money damages would not provide an adequate remedy to Somaxon. Somaxon shall also have any other rights and remedies available to Somaxon under law or in equity.

You agree that during the Term of this Agreement and for a period of one (1) year following termination of this Agreement, you will not (i) directly nor indirectly solicit business as to products or services competitive with those of Somaxon or any of its subsidiaries, from any of Somaxon’s or any of its subsidiaries’ customers with whom you had contact during the course of your service to Somaxon or within one year prior to the termination of this Agreement; or (ii) directly or indirectly induce or solicit any of the Company’s employees or consultants to leave their employment.

The arbitrator shall have the authority to award any remedy or relief that a court of competent jurisdiction could order or grant, including, without limitation, the issuance of an injunction. However, either party may, without inconsistency with this arbitration provision, apply to any court having jurisdiction over such dispute or controversy and seek interim provisional, injunctive or other equitable relief until the arbitration award is rendered or the controversy is otherwise resolved. Except as necessary in court proceedings to enforce this arbitration provision or an award rendered hereunder, or to obtain interim relief, neither a party nor an arbitrator may disclose the existence, content or results of any arbitration hereunder without the prior written consent of Somaxon and you.
