operating programs, budgets, procedures, and directions established from time to
time by the Company (the "Services"). The Employee shall devote his best efforts
and full business and professional time, attention, energy, loyalty, and skill
to the rendering of the Services on behalf of the Company, to the business
affairs of the Company, and to the advancement of the Company's interests. The
Employee shall initially have the title of "Regional Vice President," subject to
the Company's right to change such title consistent with the Employee's duties
and responsibilities from time to time.

         (iv)   Compensation. As compensation for his services under this
agreement, the Company shall pay the Employee a base salary at the annual rate
of $199,680 (the "Base Salary"), payable in accordance with the Company's
general policies and procedures for payment of salaries to its executive
personnel. The Employee's performance shall be reviewed annually for the purpose
of considering potential increases in the Base Salary, but the Company shall not

         contemplated by the Purchase Agreement (as defined in (S)6, below), the
         benefits described in this (S)5(a) are being provided through the

         of New York (as defined in (S)6, below) and Capitol Professional
         Employer, Inc., a New York corporation dba "The Capital Group," that
         such arrangement is being made solely for purposes of convenience to
         the Employee, and that without such arrangement the Company would not

         the Employee during such transition period;

                (b)  Four weeks paid vacation during each year of this
         agreement; and

         generally to the Company's executive personnel from time to time

         the board of directors of the Company, including without limitation
         participation in the Company's 1997 Employee Stock Purchase Plan and
         Amended and Restated 1996 Stock Option Plan, each as in effect from
         time to time.

         action which would tend to disparage or diminish the reputation of any
         Affiliated Company.

include the Company and all subsidiaries or affiliates of the Company other than
Summit Ventures IV, L.P., (ii) "Confidential Information" shall mean all trade
secrets, proprietary data, and other confidential information of any Affiliated

agreement to which it is a party or otherwise bound; (iii) "Restricted Period"
shall mean the period beginning on the Commencement Date and ending on the later

employment with the Company, and, with respect to the remaining sections of this
agreement, the geographic area within a radius of 25 miles from any facility or
operation leased, owned, managed, or operated by any Affiliated Company.

         The Employee acknowledges that (A) the provisions of this section are
fundamental and essential for the protection of the Company's legitimate
business and proprietary interests, (B) such provisions are reasonable and
appropriate in all respects, and (C) in the event of any violation by the
Employee of any of such provisions, the Company would suffer irreparable harm
and its remedies at law would be inadequate. In the event of any violation or
attempted violation of such provisions by the Employee, the Company shall be
entitled to a temporary restraining order, temporary and permanent injunctions,
specific performance, and other equitable relief, without any showing of
irreparable harm or damage or the posting of any bond, in addition to any other
rights or remedies which may then be available to the Company.

         (vii)  Termination. The Employee's employment with the Company shall
terminate automatically upon the death of the Employee, may be terminated by the

         Employee; provided that if the Company terminates the Employee's
         employment pursuant to this clause (c) and no other basis for
         termination exists under this agreement, then the Employee shall be
         entitled to severance payments in an aggregate amount equal to the Base
         Salary then in effect prorated for the period equal to the lesser of 12
         months or the time remaining in the then-current term after the
         effective date of such termination. Any such severance payments shall
         be payable periodically in the same manner as the Base Salary is
         payable under (S)4 of this agreement, and, notwithstanding any other
         provisions of this agreement to the contrary, such severance payments
         shall be payable only so long as the Employee is in full compliance
         with the provisions of (S)6 of this agreement.

         For purposes of this agreement:

                (i)  "Cause" shall mean:

<PAGE>

                     (A) any act constituting (1) a felony under the federal
                laws of the United States, the laws of any state, or any other
                applicable law, (2) fraud, embezzlement, misappropriation of
                assets, willful misfeasance, or dishonesty, or (3) other
                criminal conduct which in any way materially and adversely
                affects the reputation, goodwill, or business position of the
                Company;

                     (B) the failure of the Employee to perform and observe all
                material obligations and conditions to be performed and observed
                by the Employee under this agreement, or to perform his duties
                in accordance with the policies, programs, budgets, procedures,
                and directions established from time to time by the COO or the
                Company (any such failure, a "Performance Failure"), and to
                correct such Performance Failure promptly following notice from
                the Company to do so; or

                     (C) having corrected (or the Company having waived the
                correction of) a Performance Failure, the occurrence of any
                subsequent Performance Failure; and

                (ii) "Long-Term Disability" shall mean that, because of physical
         or mental incapacity, it is more likely than not that the Employee will
         be unable, within 180 days after such incapacity commenced, to perform
         the essential functions of his position with the Company, with or
         without reasonable accommodation. In the event of any disagreement
         about whether or when the Employee is under a Long-Term Disability, the
         question shall be determined: (A) by a physician selected by agreement
         between the Employee and the Company if such a physician is selected
         within 10 days after either of them requests the other so to agree; or,
         if not, (B) by two physicians, the first of whom shall be selected by
         the Employee and the second of whom shall be selected by the Company
         or, if the Employee fails to make a selection within 10 days after
         being requested to do so by the Company, the second physician shall be
         selected by the first physician; or, if the two physicians fail to
         agree, (C) by a third physician selected by the first two physicians.
         The Employee shall submit to all reasonable examinations requested by
         any such physicians.

         (viii) Capacity. The Employee represents and warrants to the Company
that he has the capacity and right to enter into this agreement and perform all
of his obligations under this agreement without any restriction.

         (ix)   Remedies. Subject to the right of the Company and the Affiliated
Companies to exercise the remedies described in the last paragraph of 6 of this
agreement in any court having jurisdiction, all disagreements and controversies
arising with respect to this agreement, or with respect to its application to
circumstances not clearly set forth in this agreement, shall be settled by
binding arbitration to be held, and the award made, in Albany, New York,
pursuant to the then-applicable Commercial Arbitration Rules of the American
Arbitration Association. In any such arbitration, the arbitrators shall consist
of a panel of three arbitrators, which shall act by majority vote and which
shall consist of one arbitrator selected by the Party on one side of the issue
subject to the arbitration, one arbitrator selected by the Party on the other
side of the issue, and a third arbitrator selected by the two arbitrators so
selected, who shall be either a certified public accountant or an attorney at
law licensed to practice in the State of New York and who shall act as chairman
of the arbitration panel; provided that if the Party on one side of the issue
selects its arbitrator for the panel and the other Party fails so to select its
arbitrator within 10 business days after being requested by the first Party to
do so, then the sole arbitrator shall be the arbitrator selected by the first
Party. A decision in any such arbitration shall apply both to the particular
question submitted and to all similar questions arising thereafter and shall be
binding and conclusive upon both Parties and shall be enforceable in any court
having jurisdiction over the Party to be charged.

         All costs and expenses of arbitration shall be borne by the Parties as
determined by the arbitrator or arbitration panel, except that the fees and
expenses of any arbitrator on an arbitration panel who is selected individually
by a Party shall be borne separately by the Party appointing the arbitrator;
provided that if one Party fails to select an arbitrator for a panel, and the
sole arbitrator is the arbitrator selected by the other Party, then the fees of
that arbitrator shall be borne by the Parties as determined by that arbitrator.

                                       4

         All rights and remedies of either Party under this agreement are
cumulative and in addition to all other rights and remedies which may be
available to that Party from time to time, whether under any other agreement, at
law, or in equity.

         (x)    Survival. The termination of the Employee's employment with the
Company (for any reason) shall not relieve either Party of any of that Party's
obligations under this agreement existing at, arising as a result of, or
relating to acts or omissions occurring prior to, such termination. Without
limiting the generality of the preceding sentence, in no event shall the
termination of such employment modify or affect any obligations of the Employee
or rights of the Company under (S)6 of this agreement, all of which shall
survive the termination of such employment.

agreement to any Party shall be in writing and shall be deemed given when

with all rules, laws, and public policies to the extent possible. If and to the
extent that any court of competent jurisdiction is unable so to construe any
provision of this agreement and holds that provision to be invalid, such
invalidity shall not affect the remaining provisions of this agreement, which
shall remain in full force and effect. With respect to any provision in this
agreement finally determined by such a court to be invalid or unenforceable,
such court shall have jurisdiction to reform this agreement to the extent
necessary to make such provision valid and enforceable, and, as reformed, such

         (xiii) Non-Waiver. No failure by either Party to insist upon strict
compliance with any term of this agreement, to exercise any option, to enforce
any right, or to seek any remedy upon any default of the other Party shall
affect, or constitute a waiver of, the other Party's right to insist upon such
strict compliance, exercise that option, enforce that right, or seek that remedy
with respect to that default or any prior, contemporaneous, or subsequent
default. No custom or practice of the Parties at variance with any provision of
this agreement shall affect, or constitute a waiver of, either Party's right to
demand strict compliance with all provisions of this agreement.
