employees.

incurred by persons holding positions of like responsibility, including, without
limitation, travel, entertainment and similar expenses incurred for the benefit
of the Company. Subject to the Company's policy regarding the reimbursement of
such expenses as in effect from time to time during the Employment Period, which
does not necessarily allow reimbursement of all such expenses, the Company shall
reimburse the Employee for such expenses from time to time, at the Employee's
request, and the Employee shall account to the Company for all such expenses.

the Employee.

           5.5 GOOD REASON. The Employee may terminate this Agreement for Good
Reason, upon written notice to the Company delivered in accordance with Sections

           a lump sum in cash within 30 days after the Date of Termination, the

                     Employee;

                     through the Date of Termination; and

                               (3) in the case of compensation previously
                     deferred by the Employee, all amounts of such compensation
                     previously deferred and not yet paid by the Company; and

                     (b) the Company shall, promptly upon submission by the
           Employee of supporting documentation, pay or reimburse to the
           Employee any costs and expenses paid or incurred by the Employee

of the Employment Period. The Company may purchase insurance to cover all or any
part of the obligation contemplated in the foregoing sentence, and the Employee
agrees to submit to a physical examination to facilitate the procurement of such
insurance. If the physical examination reveals that the Employee is uninsurable,
such death benefit referred to in this Section 6.2 shall not be provided, and
the Employee's estate shall be entitled to receive only those death benefits to
which it is entitled under the Company's benefit plans.

           6.3 GOOD REASON; WITHOUT CAUSE. If this Agreement shall be terminated
either by the Employee for Good Reason or by the Company Without Cause:

<PAGE>

           Employee of supporting documentation, pay or reimburse to the
           Employee any costs and expenses paid or incurred by the Employee

           terminated; and

                     (d) the Company shall pay to the Employee, in equal
           semi-monthly installments, the Base Salary for the remainder of the
           Employment Period.

7.         EMPLOYEE'S OBLIGATION TO AVOID CONFLICTS OF INTEREST.

           7.1 Consistent with the Employee's fiduciary duties to the Company,
the Employee agrees that he shall not knowingly become involved in a conflict of
interest with the Company, or upon discovery thereof, allow such a conflict to
continue. The Employee further agrees to disclose to the Company, promptly after
discovery, any facts or circumstances which might involve a conflict of interest
with the Company.

           7.2 The Company and the Employee recognize that it is impossible to
provide an exhaustive list of actions or interests which constitute a "conflict
of interest." Moreover, the Company and the Employee recognize that there are
many borderline situations. In some instances, full disclosure of facts by the
Employee to the Company is all that is necessary to enable the Company to
protect its interests. In others, if no improper motivation appears to exist and
the Company's interests have not suffered, prompt elimination of the outside
interest will suffice. In still others, it may be necessary for the Company to
terminate the employment relationship. The Company and the Employee agree that
the Company's determination as to whether or not a conflict of interest exists
shall be conclusive. The Company reserves the right to take such action as, in
its judgment, will end the conflict of interest.

           7.3 In this connection, it is agreed that any direct or indirect
interest in, connection with or benefit from any outside activities,
particularly commercial activities, which interest might in any way adversely
affect the Company or its Affiliates, involves a possible conflict of interest.
Circumstances in which a conflict of interest on the part of the Employee would
or might arise, and which should be reported immediately to the Company,
include, but are not limited to, the following:

                     (a) Ownership of a material interest in any lender,
           supplier, contractor, subcontractor, customer or other entity with
           which the Company does business.

                                        8

<PAGE>
                     (b) Acting in any capacity, including director, officer,
           partner, consultant, employee, distributor, agent or the like, for
           any lender, supplier, contractor, subcontractor, customer or other
           entity with which the Company does business.

                     (c) Acceptance, directly or indirectly, of payments,
           services or loans from a lender, supplier, contractor, subcontractor,
           customer or other entity with which the Company does business,
           including, without limitation, gifts, trips, entertainment or other
           favors of more than a nominal value, but excluding loans from
           publicly held insurance companies and commercial or savings banks at
           market rates of interest.

                     (d) Use of information or facilities to which the Employee
           has access in a manner which will be detrimental to the Company's
           interests, such as use for the Employee's own benefit of know-how or
           information developed through the Company's business activities.

                     (e) Disclosure or other misuse of information of any kind
           obtained through the Employee's connection with the Company.

                     (f) Acquiring or trading in, directly or indirectly, other
           properties or interests connected with the design or marketing of
           products or services designed or marketed by the Company.

8.         EMPLOYEE'S CONFIDENTIALITY OBLIGATION.

           8.1 The Employee hereby acknowledges, understands and agrees that all

           have been or are being discussed;

           8.3 As a consequence of the Employee's acquisition or anticipated
acquisition of Confidential Information, the Employee shall occupy a position of
trust and confidence with respect to the affairs and business of the Company and
its Affiliates. In view of the foregoing and of the consideration to be provided
to the Employee, the Employee agrees that it is reasonable and necessary that
the Employee make each of the following covenants:

                     (a) Until the Date of Termination and at all times
           thereafter, the Employee shall not disclose Confidential Information
           to any person or entity, either inside or outside of the Company,
           other than as necessary in carrying out his duties and
           responsibilities as set forth in Section 2 hereof, without first
           obtaining the Company's prior written consent (unless such disclosure
           is compelled pursuant to court orders or subpoena, and at which time
           the Employee shall give notice of such proceedings to the Company).

                     (b) Until the Date of Termination and at all times
           thereafter, the Employee shall not use, copy or transfer Confidential
           Information other than as necessary in carrying out his duties and
           responsibilities as set forth in Section 2 hereof, without first
           obtaining the Company's prior written consent.

                     (c) On the Date of Termination, the Employee shall promptly
           deliver to the Company (or its designee) all written materials,
           records and documents made by the Employee or which came into his
           possession on or before the Date of Termination (even if prior to the
           date hereof) concerning the business or affairs of the Company or its
           Affiliates, including, without limitation, all materials containing
           Confidential Information.

                                       10

9.         DISCLOSURE OF INFORMATION, IDEAS, CONCEPTS, IMPROVEMENTS, DISCOVERIES
           AND INVENTIONS.

           As part of the Employee's fiduciary duties to the Company, the
Employee agrees that during his employment by the Company and for a period of
three years following the Date of Termination, the Employee shall promptly
disclose in writing to the Company all information, ideas, concepts,
improvements, discoveries and inventions, whether patentable or not, and whether
or not reduced to practice, which are conceived, developed, made or acquired by
the Employee, either individually or jointly with others, and which relate to
the business, products or services of the Company or its Affiliates,
irrespective of whether the Employee used the Company's time or facilities and
irrespective of whether such information, idea, concept, improvement, discovery
or invention was conceived, developed, discovered or acquired by the Employee on
the job, at home, or elsewhere. This obligation extends to all types of
information, ideas and concepts, including information, ideas and concepts
relating to new types of services, corporate opportunities, acquisition
prospects, the identity of key representatives within acquisition prospect
organizations, prospective names or service marks for the Company's business
activities, and the like.

10.        OWNERSHIP OF INFORMATION, IDEAS, CONCEPTS, IMPROVEMENTS, DISCOVERIES
           AND INVENTIONS, AND ALL ORIGINAL WORKS OF AUTHORSHIP.

           10.1 All information, ideas, concepts, improvements, discoveries and
inventions, whether patentable or not, which are conceived, made, developed or
acquired by the Employee or which are disclosed or made known to the Employee,
individually or in conjunction with others, during the Employee's employment by
the Company and which relate to the business, products or services of the
Company or its Affiliates (including, without limitation, all such information
relating to corporate opportunities, research, financial and sales data, pricing
and trading terms, evaluations, opinions, interpretations, acquisition
prospects, the identity of customers or their requirements, the identity of key
contacts within the customers' organizations or within the organization of
acquisition prospects, marketing and merchandising techniques, and prospective
names and service marks) are and shall be the sole and exclusive property of the
Company. Furthermore, all drawings, memoranda, notes, records, files,
correspondence, manuals, models, specifications, computer programs, maps and all
other writings or materials of any type embodying any of such information,
ideas, concepts, improvements, discoveries and inventions are and shall be the
sole and exclusive property of the Company.

           10.2 In particular, the Employee hereby specifically sells, assigns,
transfers and conveys to the Company all of his worldwide right, title and
interest in and to all such information, ideas, concepts, improvements,
discoveries or inventions, and any United States or foreign applications for
patents, inventor's certificates or other industrial rights which may be filed
in respect thereof, including divisions, continuations, continuations-in-part,
reissues and/or extensions thereof, and applications for registration of such
names and service marks. The Employee shall assist the Company and its nominee
at all times, until the Date of Termination and at all times thereafter, in the
protection of such information, ideas, concepts, improvements, discoveries or
inventions,

                                       11

<PAGE>
both in the United States and all foreign countries, which assistance shall
include, but shall not be limited to, the execution of all lawful oaths and all
assignment documents requested by the Company or its nominee in connection with
the preparation, prosecution, issuance or enforcement of any applications for
United States or foreign letters patent, including divisions, continuations,
continuations-in-part, reissues and/or extensions thereof, and any application
for the registration of such names and service marks.

           10.3 In the event the Employee creates, during the Employee's
employment by the Company, any original work of authorship fixed in any tangible
medium of expression which is the subject matter of copyright (such as,
videotapes, written presentations on acquisitions, computer programs, drawings,
maps, architectural renditions, models, manuals, brochures or the like) relating
to the Company's business, products or services, whether such work is created
solely by the Employee or jointly with others, the Company shall be deemed the
author of such work if the work is prepared by the Employee within the scope of
his employment; or, if the work is not prepared by the Employee within the scope
of his employment but is specially ordered by the Company as a contribution to a
collective work, as a part of a motion picture or other audiovisual work, as a
translation, as a supplementary work, as a compilation or as an instructional
text, then the work shall be considered to be a work made for hire, and the
Company shall be the author of such work. If such work is neither prepared by
the Employee within the scope of his employment nor a work specially ordered and
deemed to be a work made for hire, then the Employee hereby agrees to sell,
transfer, assign and convey, and by these presents, does sell, transfer, assign
and convey, to the Company all of the Employee's worldwide right, title and
interest in and to such work and all rights of copyright therein. The Employee
agrees to assist the Company and its Affiliates, at all times, until the Date of
Termination and at all times thereafter, in the protection of the Company's
worldwide right, title and interest in and to such work and all rights of
copyright therein, which assistance shall include, but shall not be limited to,
the execution of all documents requested by the Company or its nominee and the
execution of all lawful oaths and applications for registration of copyright in
the United States and foreign countries.

11. CERTAIN REDUCTION OF PAYMENTS BY THE COMPANY. Anything in this Agreement to
the contrary notwithstanding, in the event it shall be determined that any
payment or distribution by the Company to or for the benefit of the Employee
(whether paid or payable or distributed or distributable pursuant to the terms
of this Agreement or otherwise) (a "Payment") would be nondeductible by the
Company for federal income tax purposes because of Section 280G of the Code,
then the aggregate present value of amounts payable or distributable to or for
the benefit of the Employee pursuant to this Agreement (such payments or
distributions pursuant to this Agreement are hereinafter referred to as
"Agreement Payments") shall be reduced (but not below zero) to the Reduced
Amount. The "Reduced Amount" shall be an amount expressed in present value which
maximizes the aggregate present value of Agreement Payments without causing any
Payment to be nondeductible by the Company because of Section 280G of the Code.
Anything in this Agreement to the contrary notwithstanding, if the Reduced
Amount is zero and it is determined further that any Payment which is not an
Agreement Payment would nevertheless be nondeductible by the Company for federal
income tax purposes because of Section 280G of the

                                       12

<PAGE>
Code, then the aggregate present value of Payments, which are not Agreement
Payments, shall also be reduced (but not below zero) to an amount expressed in
present value which maximizes the aggregate present value of Payments without
causing any Payment to be nondeductible by the Company because of Section 280G
of the Code. For purposes of this Section 11, present value shall be determined
in accordance with Section 280G(d)(4) of the Code. All determinations required
to be made under this Section 11 shall be made by the Company's independent
certified public accountant (the "Accounting Firm") which shall provide detailed
supporting calculations both to the Company and the Employee within 15 business
days of the Date of Termination. Any such determination by the Accounting Firm
shall be binding upon the Company and the Employee. The Employee shall determine
which and how much of the Agreement Payments (or, at the election of the
Employee, other Payments) shall be eliminated or reduced consistent with the
requirements of this Section 11; provided, that if the Employee does not make
such determination within ten business days of the receipt of the calculations
made by the Accounting Firm, the Company shall elect which and how much of the
Agreement Payments shall be elimi nated or reduced consistent with the
requirements of this Section 11 and shall notify the Employee promptly of such
election. Within five business days thereafter, the Company shall pay to or
distribute for the benefit of the Employee such amounts as are then due to the
Employee under this Agreement and shall promptly pay to or distribute for the
benefit of the Employee in the future such amounts as become due to the Employee
under this Agreement. As a result of the uncertainty in the application of
Section 280G of the Code at the time of the initial determination by the
Accounting Firm hereunder, it is possible that Agreement Payments will have been
made by the Company which should not have been made ("Overpayment") or that
additional Agreement Payments which have not been made by the Company could have
been made ("Underpayment"), in each case, consistent with the calculations
required to be made hereunder. In the event that the Accounting Firm determines
that an Overpayment has been made, any such Overpayment shall be treated for all
purposes as a loan to the Employee which the Employee shall repay to the
Company, together with interest at the applicable federal rate provided for in
Section 7872(E)(2) of the Code; provided, however, that no amount shall be
payable by the Employee to the Company if and to the extent such payment would
not reduce the amount which is subject to taxation under Section 4999 of the
Code. In the event that the Accounting Firm determines that an Underpayment has
occurred, any such Underpayment shall be promptly paid by the Company to or for
the benefit of the Employee, together with interest at the applicable federal
rate provided for in Section 7872(f)(2) of the Code.

12.        EMPLOYEE'S NON-COMPETITION OBLIGATION.

           12.1 (a) Until the Date of Termination, the Employee shall not,
acting alone or in conjunction with others, directly or indirectly, in any of
the business territories in which the Company or any of its Affiliates is
presently or from time to time conducting business, invest or engage, directly
or indirectly, in any business which is competitive with that of the Company or
accept employment with or render services to such a competitor as a director,
officer, agent, employee or consultant, or take any action inconsistent with the
fiduciary relationship of an employee to his employer; provided, however, that
the beneficial ownership by the Employee of

                                       13

<PAGE>
up to three percent of the Voting Stock of any corporation subject to the
periodic reporting requirements of the Exchange Act shall not violate this
Section 12.1(a).

                (b) In addition to the other obligations agreed to by the
Employee in this Agreement, the Employee agrees that until the Date of
Termination, he shall not at any time, directly or indirectly, (i) induce,
entice or solicit any employee of the Company to leave his employment, (ii)
contact, communicate or solicit any customer or acquisition prospect of the
Company derived from any customer list, customer lead, mail, printed matter or
other information secured from the Company or its present or past employees or
(iii) in any other manner use any customer lists or customer leads, mail,
telephone numbers, printed material or other information of the Company relating
thereto.

           12.2 (a) If this Agreement is terminated by the Employee for any
reason or by the Company for Cause or Disability of the Employee, then for a
period of two years following the Date of Termination, the Employee shall not,
acting alone or in conjunction with others, directly or indirectly, in any of
the business territories in which the Company or any of its Affiliates is
presently or at the Date of Termination conducting business, invest or engage,
directly or indirectly, in any business which is competitive with that of the
Company as of the Date of Termination or accept employment with or render
services to such a competitor as a director, officer, agent, employee or
consultant, or take any action inconsistent with the fiduciary relationship of
an employee to his employer; provided, however, that the beneficial ownership by
the Employee of up to three percent of the Voting Stock of any corporation
subject to the periodic reporting requirements of the Exchange Act shall not
violate this Section 12.2(a).

                (b) In addition to the other obligations agreed to by the
Employee in this Agreement, the Employee agrees that if this Agreement is
terminated by the Employee for any reason or by the Company for Cause or
Disability of the Employee, then for a period of two years following the Date of
Termination, The Employee shall not at any time, directly or indirectly, (i)
induce, entice or solicit any employee of the Company to leave his employment,
(ii) contact, communicate or solicit any customer or acquisition prospect of the
Company derived from any customer list, customer lead, mail, printed matter or
other information secured from the Company or its present or past employees or
(iii) in any other manner use any customer lists or customer leads, mail,
telephone numbers, printed material or other information of the Company relating
thereto.

           12.3 If this Agreement is terminated by the Company Without Cause,
then the Employee shall not be subject to any non-competition obligations
hereunder.

           12.4 The parties hereto acknowledge and agree that (i) the agreements
and covenants set forth in this Section 12 are being made for good and valuable
consideration, the receipt and sufficiency of which is acknowledged; (ii) the
covenants contained in this Section 12 are an important aspect of this
Agreement, and the Company would not have entered into this Agreement absent the
inclusion of this Section 12; and (iii) the restrictions imposed in this Section
12, including

                                       14

<PAGE>
the geographic area and duration of the covenants made herein, are reasonable
and necessary to protect the Company. If the Employee breaches or indicates an
intention to breach any term or provision of this Section 12, the parties hereto
agree that the Company shall be entitled to the right of both temporary and
permanent injunctive relief and/or specific performance. The right of the
Company to such relief shall not be construed to prevent the Company from
pursuing, either consecutively or concurrently, any and all other legal or
equitable remedies available to it for such breach or threatened breach,
specifically including, without limitation, the recovery of monetary damages. If
any court determines that any provision of this Section 12, or any part thereof,
is unenforceable because of the duration or geographic scope of such provision,
the parties hereto agree that such court shall have the power to reduce the
duration or geographic scope of such provision, as the case may be, and the
parties hereto agree to request the court to exercise such power, and, in its
amended form, such provision shall then be enforceable and shall be enforced.

affect any other provisions or applications of this Agreement which can be given
effect without the invalid or unenforceable provision or application.

breach of any term of this Agreement by the Employee would cause irreparable
damage to the Company and that, in the event of such breach, the Company shall
