         This will confirm that your employment and all your positions as an
officer and director of Integra, Inc. (the "Company") and its subsidiaries and
affiliates have terminated as of December 23, 1999 (the "Effective Date").

hereof; and

         (ii) provide reimbursement of up to $10,000 of any outplacement costs
you incur for any reason so long as you obtain the approval of the Company prior
to incurring such costs, which approval shall not be unreasonably withheld or
delayed.

         The benefits referred to in clause (i) shall be no less favorable to
you, in terms of amounts and deductibles and costs to you, than the coverage
provided to you under the plans providing such benefits as of the date hereof.

                             As of November 17, 1999

Eric E. Anderson, Ph.D.

Dear Eric:

         This letter sets forth our agreement with you (the "CEO") on matters
relating to your employment with Integra, Inc., a Delaware corporation (the
"Company"), as its President and Chief Executive Officer.

         1. Your employment as President and Chief Executive Officer of the
Company shall be governed by the terms hereof for an initial term commencing on
November 17, 1999 (the "Effective Date") and ending December 31, 2002, unless
sooner terminated by you or the Company as provided herein. This Agreement shall
be automatically renewed for successive one (1) year terms upon the expiration
of the initial term of this Agreement, or any renewal term of this Agreement,
unless either the Company or the CEO gives the other party at least six (6)
months written notice prior to the scheduled expiration of the initial term of
this Agreement, or any renewal term of this Agreement, that such party does not
intend to renew the Agreement. As President and Chief Executive Officer of the
Company, the CEO shall perform such duties and responsibilities appropriate to
such position as shall be assigned to the CEO by the Board of Directors of the
Company. The CEO shall report to the Board of Directors of the Company. The CEO
shall devote all his working time and efforts to the business of the Company.
The CEO represents that the CEO is not bound by the provisions of any
non-competition, confidentiality or similar agreement not heretofore disclosed
by the CEO in writing to the Company.

         2.

         2.1 The CEO's salary shall be at a rate per annum of $240,000, payable
in accordance with the normal payroll practices of the Company (the "Base
Salary"). In addition, the CEO may be entitled to receive merit increases in
salary during the term hereof in amounts and at such times as shall be
determined by the Board of Directors of the Company in its sole discretion based
on the CEO's performance. The CEO's salary shall be reviewed no less than once
per year.

         2.2 The CEO shall be entitled to receive a bonus for calendar year 1999
in accordance with his current agreements with the Company.

         2.3 In addition to the CEO's salary, the CEO shall be entitled to
payments pursuant to an annual bonus program commencing with calendar year 2000.
Under the bonus

                                                                               2

program, the CEO shall have an annual bonus opportunity of up to seventy-five
(75%) percent of his Base Salary at the then current rate in effect (the
"Bonus"). Bonus goals shall be mutually agreed upon between the CEO and the
Compensation Committee of the Board of Directors of the Company within the first
ninety (90) days of each calendar year for such year. Except as otherwise
provided herein, the CEO must continue in the employment of the Company through
the end of the applicable year in order to be entitled to a bonus for such year.
The bonus award shall be paid in cash, not later than four weeks following the
completion of the annual audit of the Company by the Company's independent
accountants for the applicable year.

         2.4 As promptly as practicable after execution hereof, the Company
shall cause to be granted to the CEO options to purchase an aggregate of 500,000
shares of common stock $.01 par value (the "Common Stock"), of the Company at an
exercise price equal to the fair market value on the date of grant. The options
shall be governed by the terms and conditions of the Company's 1999 Stock Option
Plan, as it may be amended from time to time (the "Plan"), and of the stock
option certificate issued to the CEO. Such options shall vest as follows: 25% on
the date of grant and 25% per year over the three year period after the date of
grant. The options shall vest in full upon a sale of all or substantially all
the assets of the Company or upon the occurrence of a transaction (merger,
consolidation, etc.) which results in the holders of the Common Stock prior to
the transaction owning less than 50% of the Common Stock thereafter (a "Change
in Control"). The options granted hereunder are in addition to any options
heretofore granted under other stock plans of the Company. The CEO will be
eligible for future option grants in the discretion of the Board's stock option
committee.

         3. The CEO shall be entitled to participate in the employee benefit
plans and programs offered by the Company from time to time applicable to
executives of the Company, including group insurance and supplemental life and
disability plans, subject to the provisions of such plans and programs from time
to time in effect. The CEO shall be entitled to twenty days of paid time off per
year plus sick leave, to accrue and to be taken in accordance with Company
policy. In addition, commencing March 1, 2000, the Company shall lease an
automobile for use by the CEO at the Company's expense at a monthly lease
expense of approximately $600, shall pay for insurance for such leased vehicle
and shall reimburse the CEO for gasoline, tolls and parking in connection with
business related travel upon the presentation of proper accounts therefor in
accordance with the Company's policies. During the term of this Agreement, the
Company shall reimburse the CEO for the premiums due on his current long-term
disability insurance policy.

         4. The CEO agrees that the CEO shall not, at any time, use any
Confidential Information (as hereinafter defined) except in the regular course
of the CEO's employment hereunder, or disclose any Confidential Information to
any person or entity other than an employee or professional adviser of the
Company. "Confidential Information" means any information of a confidential or
proprietary nature relating to the business of the Company and its clients;
provided, however, that Confidential Information shall not include information
which (i) becomes generally available to the public other than as a result of an
unauthorized disclosure by the CEO, (ii) was available to the CEO on a
non-confidential basis prior to the CEO's employment with the Company or (iii)
becomes available to the CEO on a non-confidential basis from a source other
than the Company or any of its affiliates, provided that such source is not
bound by a confidentiality agreement with the Company.

         5. The CEO agrees that the CEO shall not, during the period of the
CEO's employment, and for a period of one year thereafter (the "Section 5
Period") following termination of the CEO's employment, whether by the CEO or by
the Company, (a) engage, whether as principal, agent, investor (except as an
owner of less than a 5% interest in a publicly held company), distributor,
representative, stockholder, employee, consultant, volunteer or otherwise, with
or without pay, in any activity or business venture anywhere in the United
States which is directly competitive with the business of the Company or any
other member of the Company Group (as hereinafter defined), (b) without written
permission of the Company, solicit or entice or endeavor to solicit or entice
away from the Company any person who was or is at the time of solicitation an
employee of the Company or any other member of the Company Group, either for the
CEO's own account or for any individual, firm or corporation, whether or not
such person would commit any breach of his contract of employment by reason of
leaving the service of the Company or any other member of the Company Group, (c)
employ, directly or indirectly, any person who was an employee of the Company or
any other member of the Company Group at the date of termination of the CEO's
employment or within one (1) month prior to such date of termination, or (d)
solicit or entice or endeavor to solicit or entice away from the Company or any
other member of the Company Group, (i) any client or customer of the Company or
(ii) any corporation, individual or firm with which the Company or any other
member of the Company Group, is, or has been during the last six (6) months of
the CEO's employment with the Company or any other member of the Company Group
in active negotiations in connection with becoming a client, customer,
acquisition candidate, vendor, supplier or joint venture partner of the Company
or any other member of the Company Group, either for the CEO's own account or
for any individual, firm or corporation.

         For purposes hereof, "Company Group" shall mean, collectively, the
Company and its subsidiaries, affiliates and parent entities operating from time
to time in the same lines of business for which the CEO has had responsibility.

         6. In the event of a breach or threatened breach by the CEO of any of
the provisions of Paragraphs 4 or 5 of this Agreement, the CEO hereby consents
and agrees that the Company shall be entitled to seek an injunction or similar
equitable relief from any court of competent jurisdiction restraining the CEO
from committing or continuing any such breach or threatened breach or granting
specific performance of any act required to be performed by the CEO under any of
such provisions, without the necessity of showing any actual damage or that
money damages would not afford an adequate remedy and without the necessity of
posting any bond or other security. Nothing herein shall be construed as
prohibiting the Company from pursuing any other remedies at law or in equity
which it may have.

         7.

         7.1 Upon the CEO's death, the Company will pay the CEO's estate or
other legal representative the CEO's salary (at the annual rate then in effect)
accrued to the date of death and not theretofore paid to the CEO. In addition,
the CEO's estate or other legal representative shall be entitled to receive the
CEO's annual bonus prorated to the date of death, but only if such bonus is
earned. Such bonus, if any, shall be paid at the time set forth in Section 2.3.
The rights and benefits of the CEO's estate or other legal representative under
the benefit plans and programs of the Company shall be determined by reference
to the provisions of
<PAGE>   4
                                                                               4

such plans and programs of the Company at the time in effect. The estate or
other legal representative of the CEO and the Company shall have no further
rights or obligations under this Agreement.

         7.2 If the CEO shall become incapacitated by reason of sickness,
accident or other physical or mental disability and shall for a period of sixty
(60) consecutive days be unable to materially perform his duties hereunder, with
or without reasonable accommodation, the employment of the CEO hereunder may be
terminated by the Company upon thirty (30) days' (the "Notice Period") notice to
the CEO; provided, however, that the CEO's employment by the Company shall not
be terminated pursuant to this Paragraph 7.2 if the CEO returns to work and is
able to materially perform his duties hereunder during the Notice Period. In the
event of such termination, the Company shall pay the CEO his salary (at the
annual rate then in effect) accrued to the effective date of such termination
and not theretofore paid to the CEO. In addition, the CEO shall be entitled to
receive the CEO's annual bonus prorated to the effective date of termination,
but only if such bonus is earned. Such bonus, if earned, shall be paid at the
time set forth in Section 2.3. The CEO's rights under the benefit plans and
programs of the Company shall be determined by reference to the provisions of
such plans and programs at the time in effect. In the event of such termination,
neither the CEO nor the Company shall have any further rights or obligations
under this Agreement, except as set forth in Paragraphs 4, 5 and 6.

         7.3 The employment of the CEO hereunder may be terminated by the
Company at any time during the term of this Agreement for Due Cause (as
hereinafter defined). In the event of such termination, the Company shall pay to
the CEO his salary (at the annual rate then in effect) accrued to the date of
such termination and not theretofore paid to the CEO, and, after the
satisfaction of any claim of the Company against the CEO arising as a direct and
proximate result of such Due Cause, neither the CEO nor the Company shall have
any further rights or obligations under this Agreement, except as provided in
Paragraphs 4, 5 and 6. Rights and benefits of the CEO under the benefit plans
and programs of the Company will be determined in accordance with the terms and
provisions of such plans and programs. For purposes hereof, "Due Cause" shall
mean (i) a material breach of any of the CEO's material obligations hereunder,
(ii) that the CEO, in carrying out his duties hereunder, has been guilty of (A)
willful or gross neglect or (B) willful or gross misconduct, resulting in either
case in material harm to any member of the Company Group (as hereinafter
defined); or (iii) that the CEO has been convicted of (A) a felony or (B) any
offense involving moral turpitude. In the event of an occurrence of an event
constituting Due Cause under this Paragraph 7.3, the CEO shall be given written
notice by the Company that it intends to terminate the CEO's employment for
Cause under this Paragraph 7.3, which written notice shall specify in detail the
act or acts upon the basis of which the Company intends so to terminate the
CEO's employment. If the basis for such written notice is an act or acts
described in clause (i) above and not involving moral turpitude, the CEO shall
be given twenty (20) days to cease or correct the performance (or
nonperformance) giving rise to such written notice and, upon failure of the CEO
within such twenty (20) days to cease or correct such performance (or
nonperformance), the CEO's employment by the Company shall automatically be
terminated hereunder for Due Cause.

         7.4 The Company may terminate the CEO's employment at any time for
whatever reason it deems appropriate; provided, however, that in the event that
such termination is not pursuant to Paragraphs 7.1, 7.2 or 7.3, the Company
shall pay to the CEO (i) severance pay
<PAGE>   5
                                                                               5

in the form of salary continuation (at the annual rate then in effect) until the
expiration of the lesser of the remaining term of this Agreement or a period of
twelve (12) months (the "Salary Continuation Period") beginning on the date of
termination of employment hereunder. If a termination shall occur hereunder
within six (6) months of a Change in Control, then the Company shall pay the CEO
his salary continuation benefit in a lump sum on the date of termination and the
CEO shall be entitled to a continuation of the health, disability and life
insurance benefits provided for herein at the Company's expense for a period of
twelve (12) months. Except as provided herein, the CEO's rights and benefits
under the benefit plans and programs shall be determined by reference to the
provisions of such plans and programs at the time in effect. In the event of
such termination, neither the CEO nor the Company shall have any further rights
or obligations under this Agreement, except as set forth herein and in
Paragraphs 4, 5 and 6. An election by the Company not to renew this Agreement
made in accordance with the second sentence of Paragraph 1 shall not be treated
as a termination pursuant to this Paragraph 7.4.

         7.5 Anything herein to the contrary notwithstanding, if the Company (i)
demotes the CEO to a lesser position than provided in Paragraph 2; (ii) causes a
material change in the nature or scope of the authorities, powers, functions,
duties, or responsibilities attached to the CEO's position as described in
Section 2; or (iii) decreases the CEO's base salary or eliminates any of the
benefits or perquisites provided for in this Agreement, then, within thirty (30)
days after any occurrence set forth in clause (i), (ii) or (iii) above, the CEO
may advise the Company in writing that the action (or inaction) constitutes a
termination of his employment by the Company (other than for Due Cause), in
which event the Company shall have thirty (30) days (the "Correction Period") in
which to correct such action (or inaction). If the Company does not correct such
action (or inaction) during the Correction Period, such action (or inaction)
shall (unless consented to in writing by the Executive) constitute a termination
of the CEO's employment by the Company pursuant to Paragraph 7.4 (Without Cause)
effective on the first business day following the end of the Correction Period.

         8. This Agreement contains all the understandings and representations
between the CEO and the Company pertaining to the subject matter hereof and
supersedes all undertakings and agreements, whether oral or written, if any
there be, previously entered into by the CEO and the Company with respect
thereto.

         9. No provision of this Agreement may be amended or modified unless
such amendment or modification is agreed to in writing and signed by the CEO and
by a duly authorized representative of the Company.

personally or sent by certified mail, return receipt requested, addressed to the

party may subsequently designate by like notice:
