                  b. Executive agrees that, except in the good faith performance
of his duties and responsibilities under this Agreement or as required by order
of a court or governmental agency having jurisdiction, he will not at any time

information that (i) is or becomes known to the general public under
circumstances involving no breach by Executive of this Agreement, (ii) is
generally disclosed to third parties (excluding counsel, accountants, financial
advisors, employees, agents and material creditors of the Company) by the
Company without restriction on such third parties, or (iii) is approved for

                  c. During the Term and for a period of one (1) year from the
date of any termination (a) by the Executive prior to the expiration of the Term
(other than as provided in Section 6.d. or 6.f.) or (b) by the Company pursuant
to Section 6.c. or 6.e., Executive shall not (i) enter into the employment of,
or act as a consultant, director, officer, or employee of, or render any service
or advice to, any other business, partnership, association, corporation or other
entity whose products or activities compete in whole or in part with the
products or activities of the Company or any Affiliate, or with any contemplated
products or activities of the Company or any Affiliate as evidenced by a
business plan or other written memoranda (a "Competing Business"), or (ii)
invest or otherwise acquire any interest, whether as a shareholder, lender,
partner, proprietor, vendor or otherwise, in any Competing Business (excluding
ownership of less than 2% of a class of securities of a publicly-traded
company).

                  d. During the Term and for a period of one (1) year from the
date of any termination (a) by the Executive prior to the expiration of the Term
(other than as provided in Section 6.d. or 6.f.) or (b) by the Company pursuant
to Section 6.c. or 6.e., Executive will not, directly or indirectly, entice,

purpose of engaging in a Competing Business, or being employed or engaged by or
otherwise associated with any person or entity which is a Competing Business.

                  e. The provisions of this Section 5 shall survive the
termination of this Agreement and the termination of Executive's employment with
the Company and shall run to and inure to the benefit of the Company and its
successors and assigns. Executive represents, warrants and acknowledges that he
has carefully read this Section 5, that he has had an opportunity to have the
provisions contained herein explained to him by his attorney, and that he
understands the provisions contained herein. Executive further acknowledges
that, by reason of his training, skills, experience and employment hereunder,
the services to be rendered by him under the provisions of this Agreement and
their value to the Company are of a special, unique and extraordinary character
and that it would be difficult or impossible to replace such services,


                                      -3-
<PAGE>   4
and he further acknowledges that a violation by him of any of the provisions of
this Section 5 could cause continuing material and irreparable injury to the
Company and that in such event money damages would not be readily calculable and
the Company would not have an adequate remedy at law. Executive acknowledges and
agrees that (i) the restrictions under this Section 5 are reasonable and will
not interfere with Executive's ability to earn a livelihood or impose upon him
any undue hardship, and (ii) any breach of the covenants, provisions and
restrictions contained in this Section 5 shall cause, and shall he deemed to be,
a fundamental and material breach of Executive's fiduciary and contractual
obligations to Employer. Therefore, Executive agrees that the Company shall be
authorized and entitled to obtain from any court of competent jurisdiction,
interim and permanent equitable relief, including without limitation, injunctive
relief, in the event of any such breach or threatened breach, together with
payment of reasonable attorneys' fees and disbursements and any other costs of
enforcement incurred in connection with such breach or threatened breach. These
rights and remedies shall be cumulative and shall be in addition to any other
rights or remedies whatsoever to which the Company shall otherwise be entitled
hereunder, at law or otherwise, including the right to seek damages (including
any consequential damages) which any court of competent jurisdiction may deem
appropriate.

         6. Termination of Employment. The term of employment may terminate upon
the occurrence of any of the following events:

                  a. Termination Due to Death. Executive's employment hereunder
shall terminate upon his death. In such event his estate or his beneficiaries,
as the case may be, shall be entitled to:

                           (1)      Salary accrued through the date of death;
                                    and

                           (2)      The right to exercise any or all of his
                                    outstanding stock options (the "Options"),
                                    subject to the terms of the Stock Option
                                    Agreements (the "Option Agreements") and the
                                    applicable Stock Option Plans.

                  b. Termination Due to Disability. The Company may terminate
Executive's employment at any time on written notice after his "Disability."
"Disability" shall mean Executive's inability by reason of illness or injury
substantially to perform his duties and responsibilities under this Agreement,
as reasonably determined by a majority of the Board based upon the report of a
reputable physician designated by the Board (whom Executive shall permit to
examine him) , for a period of eight-four (84) consecutive days or one hundred
(100) days in any twelve (12) month period. In the event Executive's employment
is terminated due to his Disability, he shall be entitled to receive the
following:

                           (1)      The amount of any disability or retirement
                                    benefits provided to Executive by the
                                    Company under the provisions of any Company
                                    plan for its employees with respect to which
                                    Executive is qualified; and

                           (2)      Any accrued and unpaid salary through the
                                    effective date of termination.

                  c. Involuntary Termination for Cause. The Company may
terminate Executive's employment at any time for "Cause" on written notice.
"Cause" shall mean (i) Executive is convicted of a felony, or a misdemeanor
involving moral turpitude; or (ii) the Board determines in good faith, after
reasonable notice to Executive and an opportunity for Executive to present his
views of the relevant facts and circumstances, that Executive has (A) materially

as provided in this Agreement; (B) has breached his duty of loyalty to, or
committed any act of fraud, theft or dishonesty against, the Company or any of
its Affiliates; or (C) has violated any of his material obligations under this
Agreement after written notice and a reasonable opportunity (not to be less than
ten (10) days) to cure such default, if curable. In the event of such
termination for Cause, all rights and benefits of Executive under this Agreement
(including without limitation all unexercised options) shall immediately
terminate and in no event shall the Company be obligated to pay Executive any
compensation (other than salary and accrued and vested benefits through the date
of termination) with respect to any period before or after the date of such
termination.

                  d. Voluntary Termination by Executive. Executive may terminate
this Agreement in a "Qualifying Termination" (as defined in Section 7.d. below).

                                    his annual salary, in cash, without any
                                    offset for any compensation earned through
                                    other employment and without any obligation
                                    to mitigate damages;

                           (2)      All options previously issued to Executive
                                    shall immediately become exercisable and
                                    shall remain exercisable for two (2) years
                                    from the date of termination, in accordance
                                    with the Option Agreements.

                           (1)      Executive shall be entitled to receive in
                                    cash an amount equal to his annual salary
                                    from the effective date of such termination
                                    through the Expiration Date; provided,
                                    however, that such sum shall be offset by
                                    the amount of any compensation earned by
                                    Executive through other employment from the
                                    effective date of such termination through
                                    the Expiration Date (it being understood


                                      -5-
<PAGE>   6
                                    that Executive shall be under no obligation
                                    to mitigate his damages in such event);

                           (2)      All options previously issued to Executive
                                    shall immediately become exercisable and
                                    shall remain exercisable for two (2) years
                                    from the date of termination, in accordance
                                    with the Option Agreements.

         7. Change of Control.

                  a. In the event that Executive's employment by the Company
terminates in a Qualifying Termination (as defined in Subsection 7.d. below):

                           (1)      Executive shall be entitled to receive in
                                    cash upon the Qualifying Termination an
                                    amount equal to the greater of (a) the sum
                                    of his annual salary from the date of the
                                    Qualifying Termination through the
                                    Expiration Date or (b) twice his annual
                                    salary immediately prior to the date of the
                                    Change in Control;

                           (2)      All Options previously issued to Executive
                                    shall immediately become exercisable in
                                    accordance with the Option Agreements; and

                           (3)      The covenants contained in Subsections 5.c
                                    and 5.d. shall not apply;

                  b. Payments under this Subsection 7.a. shall be made without
regard to whether the deductibility of such payments (or any other "parachute
payments," as that term is defined in Section 28OG of the Internal Revenue Code
of 1986, as amended (the "Code"), to or for the Executive's benefit) would be
limited or precluded by Section 280G and without regard to whether such payments
(or any other "parachute payments" as so defined) would subject the Executive to
the federal excise tax levied on certain "excess parachute payments 11 under
Section 4999 of the Code; provided that if the total of all "parachute payments"
to or for the Executive's benefit, after reduction for all federal, state and
local taxes (including the tax described in Section 4999 of the Code, if
applicable) with respect to such payments (the "Total After-Tax Payments"),
would be increased by the limitation or elimination of any payment under this
Subsection 7.a., amounts payable under this Subsection 7.a. shall be reduced to
the extent, and only to the extent, necessary to maximize the Total After-Tax
Payments. The determination as to whether and to what extent payments under this
Subsection 7.a. are required to be reduced in accordance with the preceding
sentence shall be made at the Company's expense by Arthur Andersen or by such
other certified public accounting or law firm as the Board may designate prior
to a Change of Control of the Company. In the event of any underpayment or
overpayment under this Subsection 7.a. as determined by Arthur Andersen (or such
other firm as may have been designated in accordance with the preceding
sentence) , the amount of such underpayment or overpayment shall forthwith be
paid to the Executive or refunded to the Company, as the case may be, with
interest at the applicable federal rate provided for in Section 7872 of the
Code.

                  c. For purposes of this Agreement, a "Change of Control"

                                    equity securities, or

                           (2)      the stockholders of the Company approve a
                                    definitive agreement to merge or consolidate
                                    the Company with or into another corporation
                                    or person (other than a subsidiary of the

                                    all or substantially all of its assets
                                    unless at least 50% of the voting power of

                                    resulting or surviving corporation or other
                                    person from such merger or consolidation or
                                    of the corporation or other person acquiring

                  d. For purposes of this Agreement, a "Qualifying Termination"
occurs if, prior to the earlier of the Expiration Date or the second anniversary
of a Change of Control, (a) the employment of Executive is terminated other than
for Cause or (b) Executive resigns following any material impairment or material
adverse change in his working conditions, -authority, autonomy, compensation or
benefits immediately prior to the Change of Control, as the same may from time
to time have been improved, or otherwise altered with the written consent of
Executive such that his position within the Company or its successor is no
longer reasonably comparable (a "Material Adverse Change"). An assignment by the
Company of all rights and obligations hereunder to an entity into or with which
the Company merges or consolidates or to which the Company transfers
substantially all of its assets shall not constitute a Material Adverse Change
in and of itself so long as such entity fully assumes the Company's obligations
under this Agreement. In the event that both Subsection (i) 6.e. or 6.f. and
(ii) this Subsection 7.d. are applicable, the provisions of this Section shall
exclusively govern Executive's rights and remedies.

         8. Extension of Term.

         In the event that the Company participates in an initial firm
commitment underwritten public offering of shares of its Common Stock pursuant
to a registration statement filed under the Securities Act of 1933, the Company,
at its option, may extend the Term of this Agreement for one (1) additional
year, to August 31, 2004, in which event all references in this Agreement to


                                      -7-
<PAGE>   8
the Expiration Date shall mean August 31, 2004. Such option to extend shall be
exercised by written notice delivered to the Executive at any time prior to July
31, 2003.

         9. Miscellaneous.

                  a. This Agreement shall be governed by and construed and
interpreted in accordance with the laws of the State of New Hampshire without
reference to principles of conflict of laws. Any dispute, action or proceeding
arising hereunder shall be maintained in the state or federal courts located in
New Hampshire and each party hereto consents to service of process in the manner
provided in Subsection b. of this Section 8 (which shall constitute "personal
service").

                  b. Any notice given to a party shall be in writing and shall
be deemed to have been given when delivered personally or sent by certified or
registered mail, postage prepaid, return receipt requested, duly addressed to
the party concerned at the address indicated below or to such other address as
to which such party may subsequently give such notice:

                           2 International Drive, Suite 370
                           Portsmouth, NH 03801-6809

                           Attention: Compensation Committee Chairman

                           Portsmouth, New Hampshire 03801

Copies of all notices to the Company shall be sent to Richard A. Samuels,
McLane, Graf, Raulerson & Middleton Professional Association, 900 Elm Street, PO
Box 326, Manchester, NH 03105-0326.

                  c. This Agreement is personal to Executive and shall not be
assignable by Executive, except that Executive's rights to compensation and
benefits may be transferred in the event of death or Disability by will or
operation of law (subject to the terms hereof and of the applicable plans).
Subject to the provisions of Section 7.d. above, the Company may assign (without
Executive's consent) all rights and obligations hereunder to an entity into or
with which the Company merges or consolidates or to which the Company transfers
substantially all of its assets. This Agreement shall be binding upon and inure
to the benefit of Executive's heirs and legal representatives and shall be
binding upon and inure to the benefit of the Company and its successors and
assigns.

                  d. Executive and the Company each represents and warrants to
the other that such party is fully authorized and empowered to enter into this
Agreement and that the entry into and performance of such party's obligations
hereunder will not violate any agreement between such party and any other person
or entity. Executive represents and warrants that he has made a


                                      -8-

thorough investigation of and is knowledgeable about the facts and circumstances
affecting the business and prospects of the Company.

                  e. This Agreement contains the entire understanding and
agreement between the parties concerning the subject matter hereof and
supersedes all prior agreements, understandings, discussions, negotiations and
undertakings, whether written or oral, between the parties with respect thereto.
No provision hereof may be amended unless such amendment is agreed to in writing
and signed by Executive and an authorized officer of the Company acting at the
direction of the Board. No waiver by either party of any breach by the other
party of any condition or provision contained herein to be performed by such
other party shall be deemed a waiver of a similar or dissimilar condition or
provision at the same or any prior or subsequent time. Any waiver must be in
writing and signed by Executive or an authorized officer of the Company, as the
case may be.

                  f. Any provision of this Agreement that may be prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions thereof. Any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction. To the extent permitted by law, the parties hereby waive any
provision of law that renders any provision of this Agreement prohibited or
unenforceable in any respect. in addition, in the event of any such prohibition
or unenforceability, the parties agree that it is their intention and agreement
that any such provision, as written, in any jurisdiction shall nonetheless be in
force and binding to the fullest extent permitted by the law of such
jurisdiction as though such provision had been written in such a manner and to
such an extent as to be enforceable therein under the circumstances. Without
limitation of the foregoing, with respect to the restrictive covenant contained
herein, if it is determined that any such provision is excessive as to duration,
scope or area, it is intended that it nonetheless be enforced for such shorter
duration or with such narrower scope or area as will render it enforceable, and
the court making such determination shall have the power to modify such
duration, scope or area, or all of them, and/or to delete specific words or
phrases, and such provision shall then be applicable and enforceable in such
modified form.

         The parties hereto have signed this Employment Agreement as of the date
first written above.
