                         EXECUTIVE EMPLOYMENT AGREEMENT

      This Executive Employment Agreement (this "Agreement") is made as of the
1st day of July, 2006 by and between Mymetics Corporation, a Delaware
corporation (the "Company"), and Christian J.-F. Rochet, a natural person,
residing in Switzerland ("Executive").

      WHEREAS, Executive has been acting as the Company's Chief Executive
Officer under an informal agreement since August 1, 2003 and;

      WHEREAS, the Company wishes to employ Executive as its Chief Executive
Officer and Executive wishes to accept such employment and;

      WHEREAS, the Company and Executive wish to set forth the terms of
Executive's employment and certain additional agreements between Executive and
the Company.

      NOW, THEREFORE, in consideration of the foregoing recitals and the
representations, covenants and terms contained herein, the parties hereto agree
as follows:

1. Employment Period

            The Company will employ Executive, and Executive will serve the
Company, under the terms of this Agreement commencing July 1st, 2006 (the
"Commencement Date") for a term of five (5) years unless earlier terminated
under Section 4 hereof (the "Initial Term"). Notwithstanding anything to the
contrary contained in the preceding sentence, this Agreement shall be
automatically renewed for successive one-year terms (each such one-year term a
"Renewal Term"), unless sooner terminated in accordance with the provisions of
Section 4 hereof, or unless either party gives to the other party written notice
of intent not to renew the Agreement at least sixty (60) days prior to the end
of the Initial Term or any Renewal Term. The period of time between the
Commencement Date as defined above and the termination date of Executive's
employment as defined in section 4 hereunder shall be referred to herein as the
"Employment Period".

2. Duties and Status

            The Company hereby engages Executive as its Chief Executive Officer
on the terms and conditions set forth in this Agreement, including the terms and
conditions of the Employee Proprietary Information, Inventions, and
Non-Competition Agreement attached hereto as Exhibit A and incorporated herein
(the "Non-Disclosure Agreement"). During the term of the Employment Period,
Executive shall report directly to the Board of Directors of the Company (the
"Board") and shall exercise such authority, perform such executive functions and
discharge such responsibilities as are reasonably associated with Executive's
position, commensurate with the authority vested in Executive pursuant to this
Agreement and consistent with the governing documents of the Company.

<PAGE>

3. Compensation and Benefits

(a) Salary. During the Employment Period, the Company shall pay to Executive, as
compensation for the performance of his duties and obligations under this
Agreement, a base salary of (euro)18,000 per month, payable monthly or as
frequently as the Company's cash flow allows.

(b) Cash Bonuses. Executive shall be entitled to cash bonuses equal to 3% of all
payments to be received from industrial partners with whom the Company will sign
a partnership, a sale or a licensing agreement in relation to its current
technology. Such payments shall be made on an ongoing basis during the
Employment Period and the Severance Period as defined under section 5(a)(i)(A).

(c) Other Bonus. During the Employment Period, Executive shall be entitled to
discretionary bonuses in the form of shares of the Company's common stock as
decided from time to time by the Compensation Committee of the Board of
Directors, based on Executive's contribution to the Company's success.

(d) Other Benefits. During the Employment Period, Executive shall be entitled to
participate in all of the employee benefit plans, programs and arrangements of
the Company in effect during the Employment Period which are generally available
to senior executives of the Company, subject to and on a basis consistent with
the terms, conditions and overall administration of such plans, programs and
arrangements. In addition, during the Employment Period, Executive shall be
entitled to fringe benefits and perquisites comparable to those of other senior
executives of the Company including, but not limited to, twenty five (25) days
of vacation pay plus five (5) sick/personal days, to be used in accordance with
the Company's vacation pay policy for senior executives.

(e) Business Expenses. During the Employment Period, the Company shall promptly
reimburse Executive for all appropriately documented, reasonable business
expenses incurred by Executive in the performance of his duties under this
Agreement, including telecommunications expenses and travel expenses.

4. Termination of Employment

(a) Termination for Cause. The Company may terminate Executive's employment
hereunder for Cause (defined below). For purposes of this Agreement and subject
to Executive's opportunity to cure as provided in Section 4(c) hereof, the
Company shall have Cause to terminate Executive's employment hereunder if such
termination shall be the result of:

(i) a material breach of fiduciary duty or material breach of the terms of this
Agreement or any other agreement between Executive and the Company (including
without limitation any agreements regarding confidentiality, inventions
assignment and non-competition), which, in the case of a material breach of the
terms of this Agreement or any other agreement, remains uncured for a period of
thirty (30) days following receipt of written notice from the Board specifying
the nature of such breach;

(ii) the commission by Executive of any act of embezzlement, fraud, larceny or
theft on or from the Company;

(iii) substantial and continuing neglect or inattention by Executive of the
duties of his employment or the willful misconduct or gross negligence of
Executive in connection with the performance of such duties which remains
uncured for a period of thirty (30) days following receipt of written notice
from the Board specifying the nature of such breach;

<PAGE>

(iv) the commission and indictment by Executive of any crime involving moral
turpitude or a felony; and

(v) Executive's performance or omission of any act which, in the judgment of the
Board, if known to the customers, clients, stockholders or any regulators of the
Company, would have a material and adverse impact on the business of the
Company.

(b) Termination for Good Reason. Executive shall have the right at any time to
terminate his employment with the Company upon not less than thirty (30) days
prior written notice of termination for Good Reason (defined below). For
purposes of this Agreement and subject to the Company's opportunity to cure as
provided in Section 4(c) hereof, Executive shall have Good Reason to terminate
his employment hereunder if such termination shall be the result of:

(i) The Company's material breach of this Agreement; or

(ii) A requirement by the Company that Executive perform any act or refrain from
performing any act that would be in violation of any applicable law.

(iii) A change of control of the Company's Board of Directors, up to 12 months
after such change has taken place.

(iv) Board decisions which, in the view of Executive, are likely to jeopardize
past and/or potential future company products.

(v) Lack of recognition or credits for work accomplished by Executive.

(c) Notice and Opportunity to Cure. Notwithstanding the foregoing, it shall be a
condition precedent to the Company's right to terminate Executive's employment
for Cause and Executive's right to terminate for Good Reason that (i) the party
seeking termination shall first have given the other party written notice
stating with specificity the reason for the termination ("breach") and (ii) if
such breach is susceptible of cure or remedy, a period of fifteen (15) days from
and after the giving of such notice shall have elapsed without the breaching
party having effectively cured or remedied such breach during such 15-day
period, unless such breach cannot be cured or remedied within fifteen (15) days,
in which case the period for remedy or cure shall be extended for a reasonable
time (not to exceed an additional thirty (30) days) provided the breaching party
has made and continues to make a diligent effort to effect such remedy or cure.

(d) Voluntary Termination. Executive, at his election, may terminate his
employment upon not less than sixty (60) days prior written notice of
termination other than for Good Reason.

(e) Termination Upon Death or Permanent and Total Disability. The Employment
Period shall be terminated by the death of Executive. The Employment Period may
be terminated by the Board of Directors of the Company if Executive shall be
rendered incapable of performing his duties to the Company by reason of any
medically determined physical or mental impairment that can be reasonably
expected to result in death or that can be reasonably be expected to last for a
period of either (i) six (6) or more consecutive months from the first date of
Executive's absence due to the disability or (ii) nine (9) months during any
twelve-month period (a "Permanent and Total Disability"). If the Employment
Period is terminated by reason of a Permanent and Total Disability of Executive,
the Company shall give ninety (90) days' advance written notice to that effect
to Executive.

<PAGE>

(f) Termination Without Cause. The Company, at its election, may terminate
Executive's employment otherwise than for Cause, upon not less than ninety (90)
days written notice of termination.

5. Consequences of Termination

(a) Without Cause or for Good Reason. In the event of a termination of
Executive's employment during the Employment Period by the Company other than
for Cause pursuant to Section 4(f) or by Executive for Good Reason pursuant to
Section 4(b) the Company shall pay Executive (or his estate) and provide him
with the following, provided that Executive enter into a release of claims
agreement agreeable to the Company and Executive:

(i) Lump-Sum Payment. A lump-sum cash payment, payable ten (10) days after
Executive's termination of employment, equal to the sum of the following:

(A) Salary. The equivalent of the greater of (i) twenty four (24) months or (ii)
the remaining term of the Agreement (the "Severance Period") of Executive's
then-current base salary; plus

(B) Earned but Unpaid Amounts. Any previously earned but unpaid salary through
Executive's final date of employment with the Company, and any previously earned
but unpaid bonus amounts prior to the date of Executive's termination of
employment.

(ii) Bonuses. Executive (or his estate) shall be entitled to the bonuses defined
under section 3(b) until the end of the partnership, sale or license agreement
under which they were earned.

(iii) Other Benefits. The Company shall provide continued coverage for the
Severance Period under all health, life, disability and similar employee benefit
plans and programs of the Company on the same basis as Executive was entitled to
participate immediately prior to such termination, provided that Executive's
continued participation is possible under the general terms and provisions of
such plans and programs. In the event that Executive's participation in any such
plan or program is barred, the Company shall use its commercially reasonable
efforts to provide Executive with benefits substantially similar (including all
tax effects) to those which Executive would otherwise have been entitled to
receive under such plans and programs from which his continued participation is
barred. In the event that Executive is covered under substitute benefit plans of
another employer prior to the expiration of the Severance Period, the Company
will no longer be obligated to continue the coverages provided for in this
Section 5(a)(ii).

(b) Other Termination of Employment. In the event that Executive's employment
with the Company is terminated during the Employment Period by the Company for
Cause (as provided for in Section 4(a) hereof) or by Executive other than for
Good Reason (as provided for in Section 4(b) hereof), the Company shall pay or
grant Executive any earned but unpaid salary and bonus through Executive's final
date of employment with the Company, plus one month salary per year of
employment (including the initial period under an informal agreement with the
Board of Directors), plus the bonuses defined under section 3(b) which shall
remain due to Executive or his estate until the end of the partnership, sale or
license agreement under which they were earned.

(c) Withholding of Taxes. All payments required to be made by the Company to
Executive under this Agreement shall be subject only to the withholding of such
amounts, if any, relating to tax, excise tax and other payroll deductions as may
be

<PAGE>

required by law or regulation.

(d) No Other Obligations. The benefits payable to Executive under this Agreement
are not in lieu of any benefits payable under any employee benefit plan, program
or arrangement of the Company, except as specifically provided herein, and
Executive will receive such benefits or payments, if any, as he may be entitled
to receive pursuant to the terms of such plans, programs and arrangements.
Except for the obligations of the Company provided by the foregoing and this
Section 5, the Company shall have no further obligations to Executive upon his
termination of employment.

(e) No Mitigation or Offset. Executive shall have no obligation to mitigate the
damages provided by this Section 5 by seeking substitute employment or otherwise
and there shall be no offset of the payments or benefits set forth in this
Section 5 except as provided in Section 5(a)(ii).

6. Governing Law

            This Agreement and the rights and obligations of the parties hereto
shall be construed in accordance with the laws of the State of Delaware, without
giving effect to the principles of conflict of laws.

7. Indemnity and Insurance

            The Company shall indemnify and save harmless Executive for any
liability incurred by reason of any act or omission performed by Executive while
acting in good faith on behalf of the Company and within the scope of the
authority of Executive pursuant to this Agreement and to the fullest extent
provided under the Bylaws, the Certificate of Incorporation and the General
Corporation Law of the State of Delaware, except that Executive must have in
good faith believed that such action was in, or not opposed to, the best
interests of the Company, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe that such conduct was unlawful.

            The Company shall provide that Executive is covered by any Directors
and Officers insurance that the Company provides to other senior executives
and/or board members.

8. Cooperation with the Company After Termination of Employment

            Following termination of Executive's employment for any reason,
Executive shall fully cooperate with the Company, unless Executive has already
started new professional activities under non-competition agreement that limits
the cooperation, term employed under in all matters relating to the winding up
of Executive's pending work on behalf of the Company including, but not limited
to, any litigation in which the Company is involved, and the orderly transfer of
any such pending work to other employees of the Company as may be designated by
the Company. Following any notice of termination of employment by either the
Company or Executive, the Company shall be entitled to such full time or part
time services of Executive as the Company may reasonably require during all or
any part of the sixty (60)-day period following any notice of termination,
provided that Executive shall be compensated for such services at the same rate
as in effect immediately before the notice of termination.
