SEVERANCE PROTECTION AGREEMENT

Exhibit 10.1

SEVERANCE PROTECTION AGREEMENT

SEVERANCE PROTECTION AGREEMENT, dated September     , 2007, by and between MediciNova, Inc., a Delaware corporation (the “Company”), and                      (the “Executive”).

PURPOSE

The Board of Directors of the Company (the “Board”) recognizes that the possibility of a Change in Control (as hereinafter defined) of the Company exists and that the threat or occurrence of a Change in Control may result in the distraction of its key management personnel because of the uncertainties inherent in such a situation.

The Board has determined that it is essential and in the best interests of the Company and its stockholders to retain the services of the Executive in the event of the threat or occurrence of a Change in Control and to ensure the Executive’s continued dedication and efforts in such event without undue concern for the Executive’s personal financial and employment security.

In order to induce the Executive to remain in the employ of the Company, particularly in the event of the threat or occurrence of a Change in Control, the Company desires to enter into this Agreement to provide the Executive with certain benefits in the event the Executive’s employment is terminated as a result of, or in connection with, a Change in Control.

NOW, THEREFORE, in consideration of the respective agreements of the parties contained herein, it is agreed as follows:

SECTION 1. Definitions.

For purposes of this Agreement, the following terms have the meanings set forth below:

“Base Salary Amount” means the greater of the Executive’s annual base salary (a) at the rate in effect on the Termination Date and (b) at the highest rate in effect at any time during the 180-day period prior to a Change in Control, and will include all amounts of the Executive’s base salary that are deferred under any qualified or non-qualified employee benefit plan of the Company or any other agreement or arrangement.

“Beneficial Owner” has the meaning as used in Rule 13d-3 promulgated under the Securities Exchange Act. The terms “Beneficially Owned” and “Beneficial Ownership” each have a correlative meaning.

“Board” means the Board of Directors of the Company.

(c) Consummation of a reorganization, merger, or consolidation or sale or other disposition of all or substantially all of the assets of the Company (a “Business Combination”), in each case unless following such Business Combination, (i) all or substantially all of the Persons who were the Beneficial Owners, respectively, of the outstanding shares and outstanding voting securities immediately prior to such Business Combination own, directly or indirectly, more than fifty percent (50%) of the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors of the Company, as the case may be, of the entity resulting from the Business Combination (including, without limitation, an entity which as a result of such transaction owns the Company or all or substantially all of the Company’s assets either directly or through one or more subsidiaries) in substantially the same proportions as their ownership, immediately prior to such Business Combination, of the outstanding voting securities (provided, however, that for purposes of this clause (i) any shares of common stock or voting securities of such resulting entity received by such Beneficial Owners in such Business Combination other than as the result of such Beneficial Owners’ ownership of outstanding shares or outstanding voting securities immediately prior to such Business Combination shall not be considered to be owned by such Beneficial Owners for the purposes of calculating their percentage of ownership of the outstanding common stock and voting power of the resulting entity); (ii) no Person (excluding any entity resulting from such Business Combination or any employee benefit plan (or related trust) of the Company or such entity resulting from the Business Combination) beneficially owns, directly or indirectly, forty percent (40%) or more of the combined voting power of the then outstanding voting securities of such entity resulting from the Business Combination unless such Person owned forty percent (40%) or more of the outstanding shares or outstanding voting securities immediately prior to the Business Combination; and (iii) at least a majority of the members of the Board of the entity resulting from such Business Combination were members of the Incumbent Board at the time of the execution of the initial agreement, or the action of the Board, providing for such Business Combination; or

SECTION 2. Term of Agreement.

The term of this Agreement (the “Term”) will commence on the date of this Agreement, and will continue in effect until December 31, 2007; provided that on December 31, 2007 and each anniversary of such date thereafter, the Term shall automatically be extended for one additional year unless, not later than October 1 of such year, the Company or the Executive shall have given notice not to extend the Term; and further provided that in the event a Change in Control occurs during the Term, the Term will be extended to the date 24 months after the date of the occurrence of such Change in Control.

Notwithstanding the foregoing and subject to Section 3.2, the Term shall be deemed to have immediately expired without any further action and this Agreement will immediately terminate and be of no further effect if any of the following events occurs prior to a Change in Control:

(a) the Executive’s employment with the Company is terminated (whether by the Company or the Executive) for any reason;

SECTION 3. Termination of Employment.

6

(iii) subject to Section 18, and subject to the Executive providing the Company with (and not revoking) a Full Release and complying with his or her obligations under Section 6, the Company will, for a period of 24 months (the “Continuation Period”), at its expense provide to the Executive and the Executive’s dependents and beneficiaries the same or equivalent life insurance, disability, medical, dental, and hospitalization benefits (the “Continuation Period Benefits”) provided at Company expense to other similarly situated executives who continue in the employ of the Company during the Continuation Period (“similarly situated executives”). The obligations of the Company to provide the Executive and the Executive’s dependents and beneficiaries with the Continuation Period Benefits shall not restrict or limit the Company’s right to terminate or modify the benefits made available by the Company to its similarly situated executives or other employees and following any such termination or modification, the Continuation Period Benefits that Executive (and the Executive’s dependents and beneficiaries) shall be entitled to receive shall be so terminated or modified. The Company’s obligation hereunder with respect to the foregoing benefits will be limited to the extent that the Executive obtains any such benefits pursuant to a subsequent employer’s benefit plans, in which case the Company may reduce the coverage of any benefits it is required to provide the Executive hereunder as long as the coverages and benefits of the combined benefit plans are no less favorable to the Executive than the coverages and benefits required to be provided hereunder. This Section 3.1(b)(iii) will not be interpreted so as to limit any benefits to which the Executive or the Executive’s dependents or beneficiaries may be entitled under any of the Company’s employee benefit plans, programs or practices following the Executive’s termination of employment;

(iv) the Company shall provide the Executive with reasonable outplacement services suitable to the Executive’s position for a period of 12 months or, if earlier, until the first acceptance by the Executive of an offer of employment; and

(c) Subject to Section 18, the amounts provided for in Section 3.1(a) and Sections 3.1(b)(i) and (ii) will be paid in a single lump sum cash payment by the Company to the Executive within five days after the Termination Date or, if later, upon the provision of a Full Release by the Executive pursuant to Section 3.1(b)(i) and the expiration of any applicable revocation period within the time period required under Section 3.1(b)(i).

(d) The Executive will not be required to mitigate the amount of any payment provided for in this Agreement by seeking other employment or otherwise, and no such payment will be offset or reduced by the amount of any compensation or benefits provided to the Executive in any subsequent employment, except as specifically provided in Section 3.1(b)(iii) and 3.1(b)(iv).

3.2 Notwithstanding anything in this Agreement to the contrary, if, within the 30 days immediately preceding a Change in

7

Control, (i) the Executive’s employment is terminated (whether by the Company or the Executive) for any reason other than as specified in Section 3.1(a), or (ii) (A) there is a material adverse change in the Executive’s status, position or responsibilities (including reporting responsibilities) from that which applied to Executive on the date of this Agreement, and (B) the Executive’s employment with the Company is subsequently terminated within 24 months following a Change in Control (whether by the Company or the Executive) for any reason other than as specified in Section 3.1(a), the Executive shall be entitled to receive the benefits provided in Section 3.1(b), provided that the amounts provided for in Sections 3.1(b)(i) and (ii) will be paid in a single lump sum cash payment by the Company to the Executive within five days after the later of the Termination Date or the Change in Control (or, if later, upon the provision of a Full Release by the Executive pursuant to Section 3.1(b)(i) and the expiration of any applicable revocation period within such period as the Company may require, but not in excess of 60 days following the later of the Termination Date or the Change in Control, taking into account any applicable period for revocation), subject to Section 18.

3.3 Except as otherwise noted herein, the compensation to be paid to the Executive pursuant to Sections 3.1(a), 3.1(b)(i) and 3.1(b)(ii) of this Agreement (whether by reason of Section 3.1(c) or Section 3.2) will be in lieu of any similar severance or termination compensation (i.e., compensation based directly on the Executive’s annual salary or annual salary and bonus) to which the Executive may be entitled under any other Company severance or termination agreement, plan, program, policy, practice or arrangement. With respect to any other compensation and benefit to be paid or provided to the Executive pursuant to this Section 3, the Executive will have the right to receive such compensation or benefit as herein provided or, if determined by the Executive to be more advantageous to the Executive, similar compensation or benefits to which the Executive may be entitled under any other Company severance or termination agreement, plan, program, policy, practice or arrangement. The Executive’s entitlement to any compensation or benefits of a type not provided in this Agreement will be determined in accordance with the Company’s employee benefit plans and other applicable programs, policies and practices as in effect from time to time.

SECTION 4. Notice of Termination.

Following a Change in Control, any purported termination of the Executive’s employment by the Company will be communicated by a Notice of Termination to the Executive. For purposes of this Agreement, no such purported termination will be effective without such Notice of Termination.

SECTION 5. Excise Tax Adjustments.

5.1 In the event Executive becomes entitled to receive the benefits provided pursuant to Sections 3.1(b) or 3.2 herein, and the Company determines that such benefits (the “Total Payments”) will be subject to the tax (the “Excise Tax”) imposed by Section 4999 of the Code, or any similar tax that may hereafter be imposed, the Company shall compute the “Net After-Tax Amount,” and the “Reduced Amount,” and shall adjust the Total Payments as described below. The Net After-Tax Amount shall mean the present value of all amounts payable to the Executive hereunder, net of all federal income, excise and employment taxes imposed on the Executive by reason of such payments. The Reduced Amount shall mean the largest aggregate amount of the Total

8

Payments that if paid to the Executive would result in the Executive receiving a Net After-Tax Amount that is equal to or greater than the Net After-Tax Amount that the Executive would have received if the Total Payments had been made. If the Company determines that there is a Reduced Amount, the Total Payments will be reduced to the Reduced Amount. Such reduction shall be made by the Company with respect to benefits in the order and in the amounts suggested by the Executive, except to the extent that the Company determines that a different reduction or set of reductions would significantly reduce the costs or administrative burdens of the Company.

5.2 For purposes of determining whether the Total Payments will be subject to the Excise Tax and the amounts of such Excise Tax and for purposes of determining the Reduced Amount and the Net After-Tax Amount:

(a) Any other payments or benefits received or to be received by the Executive in connection with a Change in Control of the Company or the Executive’s termination of employment (whether pursuant to the terms of this Agreement or any other plan, arrangement, or agreement with the Company, or with any individual, entity, or group of individuals or entities (individually and collectively referred to in this subsection (a) as “Persons”) whose actions result in a change in control of the Company or any Person affiliated with the Company or such Persons) shall be treated as “parachute payments” within the meaning of Section 280G(b)(2) of the Code, and all “excess parachute payments” within the meaning of Section 280G(b)(1) of the Code shall be treated as subject to the Excise Tax, unless in the opinion of a tax advisor selected by the Company and reasonably acceptable to the Executive (“Tax Counsel”), such other payments or benefits (in whole or in part) should be treated by the courts as representing reasonable compensation for services actually rendered (within the meaning of Section 280G(b)(4)(B) of the Code), or otherwise not subject to the Excise Tax;

(b) The amount of the Total Payments that shall be treated as subject to the Excise Tax shall be equal to the lesser of (i) the total amount of the Total Payments; or (ii) the amount of excess parachute payments within the meaning of Section 280G(b)(1) of the Code (after applying clause (a) above);

(c) In the event that the Executive disputes any calculation or determination made by the Company, the matter shall be determined by Tax Counsel, the fees and expenses of which shall be borne solely by the Company; and

(d) The Executive shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation in the calendar year in which the Gross-Up Payment is to be made, and state and local income taxes at the highest marginal rate of taxation in the state and locality of the Executive’s residence on the effective date of employment, net of the maximum reduction in federal income taxes which could be obtained from deduction of such state and local taxes, taking into account the reduction in itemized deduction under Section 68 of the Code.

9

SECTION 6. Covenants of the Executive.

During the Continuation Period following any Change in Control pursuant to which the Executive receives the benefits pursuant to Section 3.1(b)(iii), the Executive covenants and agrees as follows:

(a) the Executive agrees to comply with his or her obligations under the any Inventions, Copyright and Confidentiality Agreement that he or she entered into with the Company; and

(b) the Executive acknowledges that the Executive has knowledge of confidential and proprietary information concerning the current salary, benefits, skills, and capabilities of Company employees and that it would be improper for the Executive to use such Company proprietary information in any manner adverse to the Company’s interests. The Executive agrees that he or she will not recruit or solicit for employment, directly or indirectly, any employee of the Company during the Continuation Period.

SECTION 7. Successors; Binding Agreement.

This Agreement will be binding upon and will inure to the benefit of the Company and its Successors, and the Company will require any Successors to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession or assignment had taken place. Neither this Agreement nor any right or interest hereunder will be assignable or transferable by the Executive or by the Executive’s beneficiaries or legal representatives, except by will or by the laws of descent and distribution. This Agreement will inure to the benefit of and be enforceable by the Executive’s legal representatives.

SECTION 8. Fees and Expenses.

The Company will pay as they become due all legal fees and related expenses (including the costs of experts) incurred by the Executive, in good faith, in (a) contesting or disputing, any such termination of employment and (b) seeking to obtain or enforce any right or benefit provided by this Agreement or by any other plan or arrangement maintained by the Company under which the Executive is or may be entitled to receive benefits. If the dispute is resolved by a final decision of an arbitrator pursuant to Section 15 in the favor of the Company, the Executive shall reimburse the Company for all such legal fees and related expenses (including costs of experts) paid by the Company on behalf of the Executive.

SECTION 9. Notice.

For the purposes of this Agreement, notices and all other communications provided for in the Agreement (including the Notice of Termination) will be in writing and will be deemed to have been duly given when personally delivered or sent by certified mail, return receipt requested, postage prepaid, addressed to the respective addresses last given by each party to the other, provided that all notices to the Company will be directed to the attention of the Board with a copy to the Secretary of the Company. All notices and communications will be deemed to have been received on the date of delivery thereof or on the third business day after the mailing thereof, except that notice of change of address will be effective only upon receipt.

10

SECTION 10. Dispute Concerning Termination.

If prior to the Date of Termination (as determined without regard to this Section 10), the party receiving the Notice of Termination notifies the other party that a dispute exists concerning the termination, the Date of Termination shall be extended until the earlier of (i) the date on which the Term ends or (ii) the date on which the dispute is finally resolved, either by mutual written agreement of the parties or by a final judgment, order or decree of an arbitrator or a court of competent jurisdiction (which is not appealable or with respect to which the time for appeal therefrom has expired and no appeal has been perfected); provided, however, that the Date of Termination shall be extended by a notice of dispute given by the Executive only if such notice is given in good faith and the Executive pursues the resolution of such dispute with reasonable diligence.

SECTION 11. Compensation During Dispute.

If a purported termination occurs following a Change in Control and during the Term and the Date of Termination is extended in accordance with Section 10 hereof, the Company shall continue to pay the Executive the full compensation in effect when the notice giving rise to the dispute was given (including, but not limited to, salary) and continue the Executive as a participant in all compensation, benefit and insurance plans in which the Executive was participating when the Notice of Termination was given, until the Date of Termination, as determined in accordance with Section 10 hereof. Amounts paid under this Section 11 are in addition to all other amounts due under this Agreement and shall not be offset against or reduce any other amounts due under this Agreement or otherwise.

SECTION 12. Nonexclusivity of Rights.

Nothing in this Agreement will prevent or limit the Executive’s continuing or future participation in any benefit, bonus, incentive or other plan or program provided by the Company for which the Executive may qualify, nor will anything herein limit or reduce such rights as the Executive may have under any other agreements with the Company (except for any severance or termination provision included in any Employment Agreement covering the Executive, which in circumstances under which amounts become payable under Section 3.1(b) hereof shall be deemed superseded completely by this Agreement and of no further force and effect). Amounts which are vested benefits or which the Executive is otherwise entitled to receive under any plan or program of the Company will be payable in accordance with such plan or program, except as specifically modified by this Agreement.

11

SECTION 13. No Set-Off.

The Company’s obligation to make the payments provided for in this Agreement and otherwise to perform its obligations hereunder will not be affected by any circumstances, including any right of set-off, counterclaim, recoupment, defense or other right which the Company may have against the Executive or others.

SECTION 14. Miscellaneous.

No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing and signed by the Executive and the Company. No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party will be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. No agreement or representation, oral or otherwise, express or implied, with respect to the subject matter hereof has been made by either party which is not expressly set forth in this Agreement.

SECTION 15. Governing Law and Binding Arbitration.

This Agreement will be governed by and construed and enforced in accordance with the laws of the State of Delaware without giving effect to the conflict of laws principles thereof. All disputes relating to this Agreement, including its enforceability, shall be resolved by final and binding arbitration before an arbitrator appointed by the Judicial Arbitration and Mediation Service (JAMS), with the arbitration to be held in San Diego, California. Judgment upon the award may be entered in any court having jurisdiction thereof.

SECTION 16. Severability.

The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or enforceability of the other provisions hereof.

SECTION 17. Entire Agreement.

This Agreement constitutes the entire agreement between the parties hereto and supersedes all prior agreements, if any, understandings and arrangements, oral or written, between the parties hereto with respect to severance protection in connection with a Change in Control.

SECTION 18. Section 409A.

18.1 Notwithstanding any provision to the contrary in this Agreement, the Company shall delay the commencement of payments or benefits coverage to which the Executive would otherwise become entitled under the Agreement in connection with his or her termination of employment until the earlier of (i) the expiration of the six-month period measured from the date of the Executive’s “separation from service” with the Company (as such term is defined in Treasury Regulations issued under Section 409A of the Code) or (ii) the

12

date of the Executive’s death, if and only if the Company in good faith determines that the Executive is a “specified employee” within the meaning of that term under Code Section 409A at the time of such separation from service and that such delayed commencement is otherwise required in order to avoid a prohibited distribution under Section 409A(a)(2) of the Code. Upon the expiration of the applicable Code Section 409A(a)(2) deferral period, all payments and benefits deferred pursuant to this Section 18 (whether they would have otherwise been payable in a single sum or in installments in the absence of such deferral) shall be paid or reimbursed to the Executive in a lump sum, and any remaining payments and benefits due under the Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein.

18.2 The provisions of this Agreement which require commencement of payments or benefits coverage subject to Section 409A upon a termination of employment shall be interpreted to require that the Executive have a “separation from service” with the Company (as such term is defined in Treasury Regulations issued under Code Section 409A).

18.3 The provisions of this Section 18 are intended to assure that any benefits provided to Executive hereunder shall comply with Code Section 409A and this Agreement shall be interpreted consistent with such section in all respects.

IN WITNESS WHEREOF, the undersigned have executed the above agreement as of the date set forth first above.
