EMPLOYMENT AGREEMENT

EMPLOYMENT AGREEMENT, effective as of August 17, 2004 (the “Commencement Date”) by and between Aphton Corporation, a Delaware corporation and its successors or assigns (the “Company”), and James F. Smith (“Executive”).

W I T N E S S E T H:

WHEREAS, the Board of Directors of the Company (the “Board”) desires to employ Executive and to assure Executive’s continued employment by the Company on the terms and conditions of this Agreement, and Executive desires to be employed by the Company on the terms and conditions of this Agreement.

NOW, THEREFORE, in consideration of the promises and mutual covenants contained herein and for other good and valuable consideration, the parties agree as follows:

1. Positions.

(a) Executive shall serve as the Chief Financial Officer of the Company.

(b) Executive shall have such duties and authority, consistent with the position of chief financial officer of a company as shall be assigned to him from time to time by the Chief Executive Officer, the Board or the Board’s Audit Committee. Executive shall report directly to the Chief Executive Officer in performing his duties hereunder.

(c) The Executive is an at will employee of the Company. Accordingly, the Company may terminate Smith Employment at any time for any lawful reason. During his term of employment (“Employment Term”), Executive shall devote all of his business time and efforts to the performance of his duties hereunder; provided, however, that Executive shall be allowed, to the extent that such activities do not materially interfere with the performance of his duties and responsibilities hereunder, to manage his passive personal interests and, subject to the next sentence, to serve on the board of directors, or on committees of such board of directors (or any similar positions), of any for-profit, charitable or civic entity. Executive may serve on such boards of directors or committees only if approved in advance by the Board (which approval may be withdrawn for any good reason, as determined by the Board in its sole discretion) and Executive shall not serve on any board of directors if such service would be inconsistent with his fiduciary responsibilities to the Company.

2. Base Salary. The Employment Term, the Company shall pay Executive a base salary at the annual rate of not less than $240,000. Base salary shall be payable in accordance with the usual payroll practices of the Company, but no less frequently than monthly. Executive’s base salary shall be reviewed annually in December by the Compensation Committee during the period of the Employment Term and may be increased, but not decreased, from time to time by the Compensation Committee and shall constitute “Base Salary” for purposes of this Agreement.

3. Incentive Compensation.

(a) Signing Bonus. Upon execution of this Agreement, Executive shall be entitled to a one-time bonus of twenty-five (25) thousand dollars.

(b) Annual Bonus. For each fiscal year after the Commencement Date and during the Employment Term, the Compensation Committee may award the Executive a bonus (the “Bonus”) in accordance with performance targets, measurements and such other criteria as shall be established for such year by the Compensation Committee on or before March 31^st of such year. The Bonus shall be earned and deemed accrued on the date the Compensation Committee approves the award of the Bonus. If awarded, the Bonus shall be paid by March 31^st of the calendar year immediately following the calendar year for which the bonus was awarded.

(c) Stock Options. Upon the Commencement Date, Executive will be granted options to purchase one hundred and fifty thousand (150,000) shares of the Company’s common stock subject to the terms set forth in the Option Agreement between the Company and Executive dated as of the same date (the “Option Agreement”). Executive shall be entitled to receive additional stock options and such other long term compensation as may be determined by the Compensation Committee from time to time in its discretion.

4. Employee Benefits and Vacation.

(a) Medical Insurance. During the Employment Term, Executive shall have the ability to participate in the Company’s comprehensive major medical and hospitalization coverage, and to the extent offered to other senior executive officers, dental and optical coverage (the “Medical Coverage”). Such Medical Coverage may be provided either through the Company’s group medical plans, by an individual policy, or by a combination of both group and individual policies. Nothing in this Agreement requires the Company to maintain any welfare or health plan in existence at the time this Agreement is executed or to create or obtain any new welfare or health plan.

(b) Vacation and Sick Leave. During the Employment Term, Executive shall be entitled to vacation each year in accordance with the Company’s policies in effect from time to time. Executive shall also be entitled to such periods of sick leave as is customarily provided by the Company to its senior executive officers. In accordance with Company policies, Executive shall have the right to carry forward unused vacation days for a calendar year to any future calendar year.

(c) Other Benefits. During the Employment Term, Executive shall be entitled to participate in all insurance, pension, long-term incentive compensation, retirement, savings, welfare and other employee benefit plans and arrangements, fringe benefits and perquisites generally provided by the Company from time to time for the benefit of comparable senior executive officers (collectively with the benefits provided pursuant to Section 4(b) above,

“Additional Benefits”). Nothing in this Agreement requires the Company to maintain any welfare or health plan in existence at the time this Agreement is executed or to create or obtain any new welfare or health plan.

5. Business Expenses. The Company shall reimburse Executive for the travel, entertainment and other business expenses incurred by Executive in the performance of his duties hereunder, including without limitation, the cost of conferences, seminars and other educational classes or meetings attended by Executive, in accordance with the Company’s policies as in effect from time to time.

6. Change of Control. (a) If Executive’s employment is terminated due to either a Termination Without Cause (as defined below) or Termination For Good Reason (as defined below) and such termination occurs within thirteen (13) months after a Change in Control (as defined below), Executive shall receive a cash lump sum within five (5) days of the date of termination in an amount equal to: (i) (A) if the Change in Control occurred prior to the accrual of a Bonus to the Executive for fiscal year 2004, two (2) times the then current Base Salary or (B) if the Change in Control occurred after the accrual of a Bonus to the Executive for fiscal year 2004, one and one-half (1.5) times the sum of the then current Base Salary plus the mean Bonus paid with respect to the prior three fiscal years; (ii) the sum of any Accrued Amounts and Other Accrued Benefits; and (iii) the aggregate amount of the premiums payable by the Company for Executive’s Medical Coverage, at the date of termination, for three (3) years.

In the event of any termination of employment under Section 6, Executive shall be under no obligation to seek other employment and there shall be no offset against any amounts due Executive under this Agreement on account of any remuneration attributable to any subsequent employment that Executive may obtain. Any amounts due under Section 6 are in the nature of severance payments and are not in the nature of a penalty. Such amounts are inclusive of, and in lieu of, any amounts payable under any other salary continuation or cash severance arrangement of the Company and to the extent paid or provided under any other such arrangement shall be offset from the amount due hereunder.

(e) Release.

Executive shall use Confidential Information only for the contemplated purposes for the sole benefit of the Company; shall not use Confidential Information for any other purpose; and shall not disclose or cause to be disclosed Confidential Information to any Executive, consultant, or third party, except as required in the course and scope of Executive’s employment by the Company and only if the Executive, consultant, or third party has executed an Agreement Not to Disclose Confidential Information. Executive further acknowledges that the Confidentiality Policy may be amended from time to time, and Executive agrees that this paragraph survives and applies to all such amendments.

(ii) The parties agree that the failure of any Confidential Information to be marked or otherwise labeled as confidential or proprietary information shall not affect its status as Confidential Information.

(iii) Executive agrees that all Confidential Information and other materials relating in any way to any Confidential Information shall be and remain the Company’s sole property during and after Executive’s employment.

(iv) Executive agrees that he will not duplicate any Confidential Information or other materials relating in any way to any Confidential Information, other than as necessary to fulfill his obligations as an officer of the Company, without the express written consent of the Company.

(v) Executive agrees to take all reasonable steps needed or requested by the Company to ensure that all Confidential Information is kept confidential.

(b) Agreement to Comply with Company Policy Regarding Inventions and Ideas. Executive acknowledges he has read and understands the Company’s Policy Regarding Inventions and Ideas (“Inventions Policy”) and that the Inventions Policy is incorporated by reference into this Agreement. Executive agrees that during and subsequent to Executive’s employment with the Company, he will abide by the Inventions Policy. Executive further acknowledges that the Inventions Policy may be amended from time to time, and Executive agrees that this paragraph survives and applies to all such amendments.

(c) Agreement Not to Compete. Executive agrees that, both during employment and for a period of two (2) years following separation from employment for any reason (the “Non-Compete Period”), Executive will not directly or indirectly (on his own behalf or on behalf of any other person or entity) engage in any business (or own an interest in an individual proprietorship, partnership, corporation, joint venture, trust or other form of business entity, whether as an individual proprietor, partner, shareholder, joint venturer, officer, director, consultant, broker, employee, sales person, trustee, independent contractor, or in any manner whatsoever (except for an ownership interest not exceeding five percent (5%) of a publicly traded entity), that is of the type and character or that is competitive with any business conducted by the Company at any time during the Employee’s employment with the Company. The parties hereby agree that the Company is currently engaged in the business of developing products using immunotherapy technology for neutralizing hormones that participate in gastrointestinal system and reproductive system cancer and non-cancer diseases and is also engaged in the business of research and development in the area of biotechnology, including but not limited to, hybridoma, monoclonal antibodies, and recombinant DNA.

(d) Agreement Not to Recruit the Company’s Employees. Executive agrees that, both during employment and for a period of two (2) years following separation from employment for any reason (the “Non-Solicit Period”), Executive will not directly or indirectly (on his own behalf or on behalf of any other person or entity) recruit, solicit or otherwise induce any Company employee or consultant to enter into an employment or a consulting relationship with any other business entity that competes with the Company.

(e) Agreement Not to Solicit the Company’s Clients/Customers. Executive agrees that, both during employment and until the end of the Non-Solicit Period, Executive will not directly or indirectly (on his own behalf or on behalf of any other person or entity), solicit any business involving or similar to any products or services produced or being developed by the Company from any Clients/Customers of the Company, or divert or attempt to divert from the Company any business relationship which existed between the Company and any Clients/Customers. For purposes of this Agreement, Clients/Customers shall include any person or entity: 1) that was a client of the Company with which Executive had contact in the course of his business responsibilities during the twelve (12) month period immediately preceding the end of Executive’s employment; and 2) about which Executive gained confidential or proprietary information belonging to the client or Company. Customer shall also mean specifically Aventis Pasteur, GlaxoSmithKline, and Schering Plough.

(f) Reasonableness of this Section 7. Executive agrees that the provisions of this Section 7 are reasonable and necessary for protection of the Company’s Confidential Information; its Clients/Customers’ Confidential Information; its business relationships with its Clients/Customers; and its undisrupted workplace.

Executive agrees that, prior to the commencement of any new employment or consultation with a person or entity in any business in which the Company operated during Executive’s employment, he will advise the person or entity of the terms of Section 7 of this Agreement. The Executive also agrees that the Company may advise any new or prospective employer of the existence and terms of this Agreement and may furnish said employer or consultant with a copy of the relevant provisions of this Agreement.

(h) Absence of Geographic Description; Savings Clause. Executive acknowledges that there are no geographic restrictions contained in this Section 7 because the Company’s business is international and not limited to any one geographic area. Notwithstanding, if a court of competent jurisdiction finds any or all of the foregoing paragraphs invalid for lack of a specific geographic restriction, Executive agrees that the applicable geographical restriction is the United States or such lesser or greater geographic area in which Executive worked or solicited Clients/Customers at any time during his employment.

(i) No Conflict With Obligations. Executive promises and represents that his employment with the Company is not in conflict with any obligations he owes to any other person or entity. Executive will notify the Company in writing before performing or causing to be performed any work for or on behalf of the Company which appears to be in conflict with: (a) rights of any nature owned or claimed by Executive in any Invention or Idea or Confidential Information, as defined in the appropriate Company Policies, conceived by him prior to

beginning work with the Company; (b) rights arising out of obligations incurred by Executive prior to beginning work for the Company; or (c) Executive’s obligations to the Company under this Agreement. In the event of Executive’s failure to give notice of any such conflict, the Company may conclude that no such conflict exists, and Executive agrees, in such event, to make no claim against the Company with respect to the use of any such Invention or Idea or Confidential Information by the Company.

(j) Remedies for Breaches of Section 7. In the event of a breach or potential breach of this Section 7, Executive acknowledges that the Company and its affiliates will be caused irreparable injury and that money damages may not be an adequate remedy and agree that the Company and its affiliates shall be entitled to injunctive relief (in addition to its other remedies at law) to have the provisions of this Section 7 enforced. It is hereby acknowledged that the provisions of this Section 7 are for the benefit of the Company and all of the affiliates of the Company and each such entity may enforce the provisions of this Section 7 and only the applicable entity can waive the rights hereunder with respect to its confidential information and Executives. Furthermore, in the event of a breach of this Section 7 by Executive while amounts under Section 6 hereof are due and owing, Executive shall not be entitled to receive any future amounts owed under Section 6 hereof, other than payment of Accrued Amounts and Other Accrued Benefits, but the Company shall remain entitled to injunctive relief in addition to any other remedies at law. In the event that the Company has breached any of its obligations to make payments to Executive under Section 6 hereof, and such breach is not remedied within 30 days of written notice, then Executive shall be relieved of his obligations under Sections 7(c), (d) and (e) hereof; provided however, that from the date that the Company shall have remedied such breach, and paid all amounts owed under Section 6, the Executive shall not take any future steps that would be in violation of Section 7(c), (d) or (e) until the end of the Non-Compete Period or the Non-Solicit Period, as the case may be; provided further, however, that in event that prior to the Company’s remedy of the breach, Executive becomes engaged in activities that would violate Sections 7(c), (d) or (e), except for this Section 7(j), then, upon the Company’s remedy of such breach, Executive shall be permitted to continue to engage in such activities, to the extent of such prior activity, subsequent to the Company’s remedy.

8. Indemnification. The Company shall indemnify and hold harmless Executive to the extent provided in the Certificate of Incorporation and By-Laws of the Company for any action or inaction of Executive while serving as an officer and director of the Company or, at the Company’s request, as an officer or director of any other subsidiary or affiliate of the Company or as a fiduciary of any benefit plan. The Company shall cover Executive under directors and officers’ liability insurance both during and, while potential liability exists, after the Employment Term in the same amount and to the same extent as the Company covers its other officers and directors.

9. Gross-Up Payment.

(a) Amount. If any payment or benefit provided to Executive by the Company (a “Base Payment”) is subject to the tax (the “Excise Tax”) imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”) (or any other similar tax that may hereafter be imposed), the Company shall pay to Executive the “Gross-Up Payment” determined

as follows. The “Gross-Up Payment” shall be equal to the sum of (i) the Excise Tax imposed with respect to the Base Payment, plus (ii) the Excise Tax imposed with respect to the Gross-Up Payment, plus (iii) all other taxes imposed on Executive with respect to the Gross-Up Payment, including income taxes and Executive’s share of FICA, FUTA and other payroll taxes. The Gross-Up Payment shall not include the payment of any tax on the Base Payment other than the Excise Tax. The Gross-Up Payment is intended to place Executive in the same economic position Executive would have been in if the Excise Tax did not apply, and shall be calculated in accordance with such intent.

(b) Tax Rates and Assumptions. For purposes of determining the amount of the Gross-Up Payment, 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 Executive’s residence on the date of termination, net of the maximum reduction in Federal income taxes which could be obtained from deduction of such state and local taxes.

(c) Payment and Calculation Procedures. The Gross-Up Payment attributable to a Base Payment shall be paid to Executive in cash and at such times as such Base Payment is paid or provided pursuant to this Agreement. Simultaneously with or prior to the Company’s payment of a Base Payment, the Company shall deliver to Executive a written statement specifying the total amount of the Base Payment and the Excise Tax and Gross-Up Payment relating to the Base Payment, if any, together with all supporting calculations and conclusions. If Executive disagrees with the Company’s determination of the Excise Tax or Gross-Up Payment, Executive shall submit to the Company, no later than thirty (30) days after receipt of the Company’s written statement, a written notice advising the Company of the disagreement and setting forth Executive’s calculation of said amounts. Executive’s failure to submit such notice within such period shall be conclusively deemed to be an agreement by Executive as to the amount of the Excise Tax and Gross-Up Payment, if any. If the Company agrees with Executive’s calculations, it shall pay any shortfall in the Gross-Up Payment to Executive within twenty (20) days after receipt of such a notice from Executive. If the Company does not agree with Executive’s calculations, it shall provide Executive with a written notice within twenty (20) days after the receipt of Executive’s calculations advising Executive that the disagreement is to be referred to an independent accounting firm for resolution. Such disagreement shall be referred to an independent accounting firm which is not the regular accounting firm of the Company and which is designated by the Company. The Company shall be required to designate such accounting firm within ten (10) days after issuance of the Company’s notice of disagreement. The accounting firm shall review all information provided to it by the parties and submit a written report to the parties setting forth its calculation of the Excise Tax and the Gross-Up Payment within fifteen (15) days after submission of the matter to it, and such decision shall be final and binding on all of the parties. The fees and expenses charged by said accounting firm shall be paid by the Company. If the amount of the Gross-Up Payment actually paid by the Company was less than the amount calculated by the accounting firm, the Company shall pay the shortfall to Executive within five (5) days after the accounting firm submits its written report. If the amount of the Gross-Up Payment actually paid by the Company was greater than the amount calculated by the accounting firm, Executive shall pay the excess to the Company within fifteen (15) days after the accounting firm submits its written report.

(d) Subsequent Recalculation. In the event the Internal Revenue Service or other applicable governmental authority imposes an Excise Tax with respect to a Base Payment that is greater than the amount of the Excise Tax determined pursuant to the immediately preceding paragraph, the Company shall reimburse Executive for the full amount of such additional Excise Tax plus any interest and penalties which may be imposed in connection therewith, and pay to Executive a Gross-up Payment sufficient to make Executive whole and reimburse Executive for any Excise Tax, income tax and other taxes imposed on the reimbursement of such additional Excise Tax and interest and penalties, in accordance with the principles set forth above.

10. Miscellaneous.

(a) Arbitration. (i) All disputes arising out of or relating to this Agreement, other than those arising out of the Company’s enforcement of Section 7 hereof, that cannot be settled by the parties shall be settled by arbitration in Philadelphia, Pennsylvania, pursuant to the rules and regulations then obtaining of the American Arbitration Association. The decision of the arbitrators shall be final and binding upon the parties, and judgment upon such decision may be entered in any court of competent jurisdiction.
