                                 MARCH 31, 2005

B. For Cause. By the Company for Cause upon notice to the Employee. "Cause"
shall mean the Employee's having engaged in fraud, embezzlement, theft,
commission of a felony or, except as may be required by law or upon advice of
counsel, his having been proven to have made an intentional unauthorized
disclosure with the knowledge that such disclosure would materially harm the
Company of trade secrets or other proprietary information of the Company or a
subsidiary in violation of written policies regarding disclosure of trade
secrets and such information, and in each case such disclosure shall have
damaged the Company or s subsidiary in a material manner.

C. Disability. By the Company upon thirty (30) days notice to the Employee, if
he should be prevented by illness, accident or other disability (mental or
physical) from discharging his duties hereunder for a period of time which would
entitle him to disability payments under any long-term disability policy held by
or paid for by the Company or, if no such policy is then in effect, for one or
more periods totaling 90 work days during any consecutive twelve (12) month
period. In the event of such termination the Company shall pay the Employee an
amount each month for twenty-four (24) months, commencing with the month of his
termination, equal to (i) his highest salary during the twelve (12) month period
ending with the month of his termination, minus (ii) the amount actually
received by the Employee for such month under any long-term disability policy
held by or paid for by the Company.



D. Death. In the event of Employee's death during the term of his employment,
the Company's obligation to pay further compensation hereunder shall cease
forthwith, except that Employee's legal representative shall be entitled to (a)
receive his monthly compensation for the period up to the last day of the month
in which such death shall have occurred and (b) receive on behalf of the
Employee's estate such benefits as to which the Employee may be entitled under
then existing; benefit policies and programs.

E. Not for Cause/Severance. By the Company other than for Cause in which event
the Company shall pay to the Employee an amount equal to six (6) months salary
as severance compensation (without regard to compensation or benefits the
Employee receives from any other source). The Employee shall be eligible for all
benefits during this 6 month period including bonuses, vesting of stock options,
health care insurance and other fringe benefits that have been ongoing prior to
the written notice(without regard to compensation or benefits the Employee
receives from any other source). The Company may elect to pay such severance
compensation in a lump sum or in equal payments over a period of not more than
six (6) months. If the Employee leaves the employ of the Company voluntarily as
a result of a breach of this Agreement by the Company, there having been as of
the date of the Company's breach no breach of this Agreement by the Employee
which has not been cured or waived, then the Employee's termination of
employment shall be deemed to have been a termination by the Company other than
for Cause. The Employee may treat reduction in rank or responsibilities as
termination of him without cause.

Notwithstanding any of the foregoing provisions of this Section 6, if the
Employee is indebted to the Company, the severance pay or other compensation
obligations of the Company shall be applied first to such indebtedness, but only
in the amount and to the extent that the Employee does not dispute, the excess,

if any, will be paid to said Employee and, in any event, the Employee shall
remain liable for any excess of his indebtedness to the Company over any amounts
owed by the Company. In addition, upon termination of the Employee's employment
(other than a voluntary termination by the Employee) all loans, expense
reimbursements and other amounts owed by the Company to the Employee (other than
severance compensation) shall become immediately due and payable.

7. Compensation Upon Termination

Upon termination of this Agreement for any reason, the Company shall promptly
compensate the Employee (or, in the event of the Employee's death, his surviving
spouse, if any, or his estate) for all unreimbursed business expenses in
accordance with the Company's expense reimbursement policy in effect at the time
the expenses were incurred.

8. Nondisclosure of Proprietary/Confidential Information

The Employee acknowledges that he will have access to information about the
Company and his employment with the Company shall, throughout the Employment
Period, bring him into close contact with many confidential affairs of the
Company, its subsidiaries and affiliates, and their respective customers,
including, without limitation, information proprietary to the Company, trade
secrets, and other confidential material, which information is not readily
available to the public and all of which is highly confidential and proprietary
and was developed at great effort and expense (such material, "Confidential
Information"). In recognition of the foregoing, during the Employment Period and
for a period of one (1) year thereafter, regardless of the reason for any
termination of employment (whether voluntary or involuntary and whether for
Cause or otherwise), the Employee shall not, without the written consent of the
Shareholders of the Company or its delegate, disclose, or use or make available
for anyone to use (except in the course of his employment hereunder and in
furtherance of the business of the Company, its subsidiaries, or its affiliates)
any Confidential Information and the Employee shall during the continuance of
his employment by the Company use his best efforts to prevent the unauthorized
publication or misuse of any Confidential Information; provided, however, that
Confidential Information shall not include any information (i) known generally
to the public (other than as a result of unauthorized disclosure by the
Employee) or (ii) developed by the Employee without violating any of the
provisions of this Agreement.

The Employee agrees that upon termination of his employment with the Company for
any reason, voluntary or involuntary, with or without Cause, he will immediately
return to the Company all Confidential Information within his possession (or
under his control), and shall not at any time thereafter copy or reproduce the
same.

9. Restrictive Covenant

(a) Employee recognizes and acknowledges that during employment the Employee
will have access to, learn, be provided with, and, in some cases, will prepare
and create certain confidential proprietary business information, including, but
not limited to, client and customer information and customer lists, all of which
are of substantial value to the Company's business. The Employee agrees that in
addition to any other limitation, for a period of twelve (12) months after the
termination of employment hereunder by him or for Cause, the Employee will not,
on his behalf or on behalf of any other person, firm, or corporation, call on
any of the Employer's customers, or any of its affiliates or subsidiaries for
the purpose of soliciting and/or providing to any of these customers any


                                       5

                        SALIVA DIAGNOSTIC SYSTEMS, INC.
                                 MARCH 31, 2005


non-public customer information relating to the Company's services, nor will the
Employee in any way, directly or indirectly, for himself, or on behalf of any
other person, firm, or corporation competing with the Company, solicit, divert,
or take away any customers of the Employer, its affiliates, or its subsidiaries.
In the event of an actual or threatened breach by the Employee of the provisions
of this paragraph, the Company shall be entitled to injunctive relief
restraining the Employee from the breach or threatened breach. Nothing herein
shall be construed as prohibiting the Company from pursuing any other remedies
available to the Company for such breach or threatened breach, including the
recovery of damages from the Employee.

(b) During the course of employment and for a period of six (6) months from the
date of termination of this Agreement by him or for Cause, Employee shall not,
directly or indirectly, individually or on behalf of persons not now parties to
this agreement, or as a partner, stockholder, director, officer, principal,
agent, employee, or in any other capacity or relationship, engage in any
business or employment, or aid or endeavor to assist any business or legal
entity to engage in the business of rapid diagnostic testing for infectious
disease or other products that directly compete with the Company's then current
customer sales (as of termination) within the United States. Employee
acknowledges the reasonableness of this restrictive covenant and the
reasonableness of the geographic area and duration which are a part of this
covenant.

(c) The Company recognizes that the Employee has had 35 years of experience in
the diagnostic and health care industry, and that concomitant with such
experience is a network of personal and business relationships already
established prior to employment with the Company, and nothing in this Section 9
will limit the business or activities of Employee except for the restriction on
information and customers set forth above.

10. Independence and Severability

Each of the rights enumerated in Sections 8 and 9 (the Restrictive Covenant,
Nondisclosure, and No-Solicitation clauses) shall be independent of the others
and shall be in addition to and not in lieu of any other rights and remedies
available to the Company at law or in equity. If any of the covenants contained
in Sections 8 or 9, or any part of any of them is hereafter construed or
adjudicated to be invalid or unenforceable, the same shall not affect the
remainder of the covenant or covenants or rights or remedies which shall be
given full effect without regard to the invalid portions. If any of the
covenants contained in Sections 8 and 9, is held to be invalid or unenforceable
because of the duration of such provision or the area covered thereby, the
parties agree that the court making such determination shall have the power to
reduce the duration and/or area of such provision and in its reduced form said
provision shall then be enforceable.

11. Solicitation of Former Employees

Employee agrees that during his employment with Employer and for twelve (12)
months, after termination of employment by him or for cause, the Employee will
not, on behalf of himself or on behalf of any, other person, firm, or
corporation, solicit for hire, nor for six months after such termination, hire
any of the professional or scientific employees of the Company employed as of
such termination.

12. Specific Remedies

(a) The Employee acknowledges that the Company shall suffer irreparable injury
if he breaches his obligations under Sections 8, 9 and 11. Accordingly, in the
event of such breach, the Employee acknowledges that the Company will be
entitled to injunctive relief in any state or federal court of competent
jurisdiction within the Commonwealth of Massachusetts. The Employee further
submits to the personal jurisdiction of such courts for the purposes of any such
action.

(b) Employee hereby acknowledges that his services are unique and extraordinary,
and are not readily replaceable, and hereby expressly agrees that the Company,
in enforcing the covenants contained herein, in addition to any other remedies
provided for herein or otherwise available at law, shall be entitled in any
court of equity having jurisdiction to an injunction restraining him in the
event of a breach, actual or threatened, of the agreements and covenants
contained in these paragraphs.

13. Employee's Duty to Mitigate

In the event Employee's employment is actually or constructively terminated by
the Company prior to the end of the Employment Period, whether or not such
termination is for Cause, Employee agrees to exert reasonable efforts to seek
alternative employment in the same or substantially similar position as that
held with the Company and at the same or substantially similar remuneration.

14. Cooperation Following Termination

Provided that he is fairly compensated for his time and reimbursed for his
out-of-pocket expenses, the Employee agrees that, following notice of
termination of his employment, (i) he will cooperate fully with the Company in
all matters relating to the completion of his pending work on behalf of the
Company and the orderly transition of such work to such other employees as the
Company may designate; and (ii) he will cooperate with the Company as to any and
all claims, controversies, disputes, or complaints over which he has any
knowledge or that may relate to him or his employment relationship with the
Company. Such cooperation includes, but is not limited to, providing the Company
with all information known to him related to such claims, controversies,
disputes, or complaints and appearing and giving testimony in any forum.

15. Arbitration

To ensure rapid and economical resolution of any and all disputes directly or
indirectly arising out of, or in any way connected or related to the Executive's
employment with the Company or the termination of that employment, the Company
and the Executive each agree that any and all such dispute, whether of law or
fact of any nature whatsoever, shall, if dispute cannot be resolved within
thirty days despite good faith negotiation, be resolved by final and binding
arbitration by Judicial Arbitration and Mediation Services, Inc. ("JAMS") in
Boston, Massachusetts. The Employee agrees to submit to binding arbitration for
the resolution of any employment related controversy, dispute or claim
("Employment Related Claim"). The term "Employment Related Claim" means any
dispute, claim, or controversy against the Company, including claims related to
salary, bonuses, stock, options, vacation pay, fringe benefits, expense
reimbursement, severance benefits, wrongful discharge, defamation, fraud, and
breach of good faith and fair dealing, whether arising out of Employee's
employment, the cessation of Employee's employment or any terms or conditions of
Employee's employment, or arising out of this Agreement (including the
restrictive covenant hereunder), which could have been brought before an
appropriate government administrative agency or in an appropriate court.

waive his right to file a complaint with the Equal Employment Opportunity
Commission pursuant to Title VII, the ADEA, and/or the OWBPA.
