     7.1  Consultant understands and acknowledges that during the term of this
Agreement, Consultant and its manager, Louis Friedman, will be exposed to
Confidential Information (as defined below) which is proprietary and which

                                       6
<PAGE>

either directly or indirectly, or disclose any of such Confidential Information
at any time, either during or after termination of this Agreement, without the
Company's prior written consent. Consultant shall take all reasonable steps to
safeguard such Confidential Information that is within its possession or control
and to protect such information against disclosure, misuse, loss or theft.
Consultant's obligations under this paragraph with respect to any specific
Confidential Information shall cease when that specific Confidential Information
becomes publicly known or when it is disclosed by any person, firm, corporation
or business entity which is not bound by the terms of a confidentiality
agreement with the Company. The term "Confidential Information" shall mean any
information not generally known in the relevant trade or industry, which was
obtained from the Company, or which was learned as a result of the performance
of any services by Consultant on behalf of the Company, and which falls within
the following general categories:

               (a) information concerning Trade Secrets of the Company;

               (b) information concerning existing or contemplated products,
     services, technology, designs, processes and research or product
     developments of the Company;

               (c) information concerning business plans, sales or marketing
     methods, methods of doing business, customer lists, customer usages and
     requirements, or supplier information of the Company; and

               (d) any other confidential information which the Company may
     reasonably have the right to protect by patent, copyright or by keeping it
     secret and confidential.

     As used herein, the term "Trade Secrets" shall mean any scientific or
     technical data, information, design, process, procedure, formula, or
     improvement that is commercially valuable to Company and is not generally
     known in the industry.

     7.2  (a)  Consultant acknowledges that in the course of providing Services
pursuant to this Agreement it will become familiar with the Company's and its
subsidiaries' Trade Secrets and with other Confidential Information and that its
Services will be of special, unique and extraordinary value to the Company and
its subsidiaries.  Therefore,  Consultant agrees that, during the term of this
Agreement (the "Non-Compete Period"), it and its manager will not directly or
indirectly, either for itself or any other person, own, manage, control,
participate in, consult with, render services for, permit its name to be used by
or in any manner engage in any business competing with the businesses of the
Company or its subsidiaries as such businesses exist or are in process on the
date of the termination of this Agreement, within (i) the City of Atlanta and
(ii) all cities, counties and towns contiguous to either the City of Atlanta.
Nothing herein will prohibit Consultant or any affiliate of Consultant from
being a passive owner of not more than 5% of the outstanding stock of any class
of a corporation which is publicly traded, so long as Consultant has no active
participation in the business of such corporation.

                                       7
<PAGE>

          (b) During the Non-Compete Period, Consultant will not directly or
indirectly through another person (i) induce or attempt to induce any employee
of the Company or any subsidiary to leave the employ of the Company or such
subsidiary, or in any way interfere with the relationship between the Company or
any subsidiary and any employee thereof, (ii)hire any person who was an employee
of the Company or any subsidiary at any time during the term of this Agreement,
or (iii)  induce or attempt to induce any customer, supplier, licensee or other
business relation of the Company or any subsidiary to cease doing business with
the Company or such subsidiary, or in any way interfere with the relationship
between any such customer, supplier, licensee or business relation and the
Company or any subsidiary.

          (c) During the Non-Compete Period, Consultant agrees not to take any
action that materially interferes with or disrupts the Company's business or its
relationships with its customers, suppliers or employees.

     7.3  Consultant acknowledges and agrees that the Company will disclose
publicly its relationship with Consultant and the material terms thereof in
order to comply with the requirements of the federal securities laws.

                                   SECTION 8

                                INDEMNIFICATION

     8.1  The Company shall indemnify and hold harmless Consultant, and
Consultant's affiliates, agents and employees ("Indemnitees"), against any and
all losses, liabilities, claims, damages or expenses whatsoever (including
reasonable legal expenses) ("Losses") to the extent such Losses arise out of or
are based upon:  (i) any representation, or any untrue statement of a material
fact contained in any information given, by the Company to any participant in a
Securities Transaction or any omission by the Company to state therein a
material fact necessary to make the statements made not misleading; (ii) any
untrue statement of a material fact contained in any application or other
papers, filed by the Company with any state or federal agency; or (iii) any act
or omission of the Company or any of its agents or employees any other violation
of state or federal securities laws based on statements, actions or inactions of
the Company, or its agents or employees.

     8.2  Consultant hereby indemnifies and agrees to defend and hold harmless
the Company and its affiliates and their respective directors, officers,
employees, representatives, and agents from and against any and all Losses to
the extent such Losses arise out of or are based upon (i) Consultant's breach of
any of Consultant's covenants, agreements, obligations or duties hereunder, and
(ii) Consultant's breach of any of the representations and warranties made by
Consultant in Section 3 hereof.

     8.3  If the indemnification provided for in this Section 8 is unavailable
to or insufficient to hold harmless the indemnified party in respect of any
Losses, the indemnifying party shall in lieu of indemnifying such indemnified
party contribute to the amount paid or payable by such indemnified party as a
result of such Losses in such proportion as is appropriate to reflect not only
(a) the relative benefits received by the Company and any person who may be

                                       8
<PAGE>

alleged to be in control of the Company within the meaning of Section 15 of the
Securities Exchange Act of 1934 (the " Controlling Person") on the one hand and
the Consultant on the other, but also (b) the relative fault of (i) the Company
and its Controlling Persons and (ii) the Consultant in connection with the
actions, inactions, statements or omissions which resulted in such Losses, as
well as any other relevant equitable considerations.  The Company and the
Consultant agree that it would not be just and equitable if contribution
pursuant to this Section 8 were determined by pro rata allocation or by any
other method of allocation which does not take account of the equitable
considerations referred to above in this subsection.  The amount paid or payable
by the indemnified party as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to above in this Section
8.3 shall be deemed to include any legal or other expenses to which such
indemnified party would be entitled if Section 8 were applied.

     8.4  The Company's and Consultant's respective obligations under this
Section 8 shall survive the completion of the Services and the termination or
cancellation of this Agreement for any reason for a period of 5 years.

                                   SECTION 9

                               NON-CIRCUMVENTION

     Company agrees not to, directly or through intermediaries, agents or
otherwise indirectly, circumvent or interfere with the business relationship
existing between the Consultant and any Introduced Person.

                                   SECTION 10

                       INVESTMENTS IN INTRODUCED PERSONS

     Company acknowledges that Consultant or one or more of its members or its
affiliates may be an investor in one or more of the Introduced Persons.
Consultant covenants and agrees  to disclose in writing any such investment in
an Introduced Person upon referring the Company to the Introduced Person or the
Introduced Person to the Company.

                                   SECTION 11

                             EMPLOYMENT AGREEMENT

        THIS EMPLOYMENT AGREEMENT, dated as of December 16, 1996, between
Mastech Systems Corporation, a Pennsylvania corporation, with its principal
executive offices at 1004 McKee Road, Oakdale, Pennsylvania 15071 (the
"Company"), and Sunil Wadhwani, an individual and resident of Allegheny
County, Pennsylvania (the "Executive").

        WHEREAS, the Executive is and has been employed by the Company and is
currently Co-Chairman and Chief Executive Officer of the Company;

        WHEREAS, the Company and the Executive desire to set forth in this
Agreement the terms on which the Company will continue to employ the Executive
and the Executive agrees to be employed by the Company;

        NOW, THEREFORE, in consideration of the mutual covenants herein
contained, and intending to be legally bound hereby, the Company and the
Executive hereby agree as follows:

        1. Position and Duties.
           -------------------

           a. The Company agrees to, and hereby does, continue to employ the
Executive for the term of this Agreement to render services to the Company as
Co-Chairman and Chief Executive Officer of the Company, (and the Executive
shall be elected to the same office and shall serve concurrently as such as an
officer of the Company's ultimate corporate parent, Mastech Corporation), and
in connection therewith, to perform such duties as the Executive is now
performing and such other duties commensurate with such positions as the
Executive may reasonably be directed to perform by the Board of Directors. The
Executive shall have the right to devote a reasonable amount of time to (i)
industry, community or charitable organizations, and (ii) the management of
personal investments, so long as such activities do not interfere or conflict
with the performance by the Executive of his obligations hereunder. Subject to
the provisions of Section 8, Section 9 and Section 10 hereof, the Executive
may serve as a director of other companies with the consent of the Board of
Directors of the Company, which consent shall not be unreasonably withheld.

           b. The Executive hereby accepts such employment and agrees
faithfully to perform to the best of his ability the duties described in
Section 1(a).

        2. Term. Subject to Section 4 hereof, the term of employment of the
           ----
Executive under this Agreement shall commence on the closing date of the
initial public offering of the Company's Common Stock (the "Effective Date")
(at which time this Agreement shall become effective) and shall terminate on
the last day of the calendar month which is 24 calendar months after the
Effective Date. Commencing on the last day of the first full calendar month
after the Effective Date and on the last day of each succeeding calendar
month, the term of this Agreement shall be automatically extended without
further action by either party for one additional calendar month unless one
party notifies the other in writing that such party does not wish to extend
the term of this Agreement. In the event that such notice shall have been
<PAGE>

delivered, the term hereof shall no longer be subject to automatic extension
and the term hereof shaft expire on the date which is 24 calendar months after
the last day of the month in which such written notice is received. (The last
day of the calendar month in which the term hereof, as extended from time to
time, shall end is hereinafter referred to as the "Expiration Date").

        3. Consummation. In consideration for the Executive's agreements
           ------------
contained herein, and as compensation to the Executive for the performance of
the services required hereunder, the Company shall pay or grant to him the
following salary and other compensation and benefits:

           a. a base salary, payable in equal installments not less frequently
than monthly, at an annual rate of not less than $300,000 per year, such
amount to be determined from time to time by the Board of Directors or an
appropriate committee thereof, provided, however, that the Executive's base
salary shall be periodically reviewed by the Board of Directors and shall be
increased if the Board of Directors determines that an increase is appropriate
on the basis of the types of factors it generally takes into account in
increasing the salaries of executive officers of the Company;

           b. an annual incentive compensation payment (bonus) of not less
than $200,000, the precise amount to be determined by the Board of Directors
and payable to the Executive no later than April 15 of each calendar year for
the prior year; provided that payment of all or a portion of such bonus may be
made subject to the attainment of reasonable Company, business unit or
individual performance goals;

           c. such other awards under the Company's 1996 Stock Incentive Plan
(the "Plan") or under any other stock option, incentive compensation or other
compensation plan, program or arrangement now existing, or hereafter adopted
and applicable to executive officers of the Company, as the Board of
Directors, or an appropriate committee thereof administering such plan,
program or arrangement, may determine appropriate in light of the duties and
responsibilities of the Executive in respect to other executive officers;

           d. participation on the same terms and conditions as all other
employees in all employee benefit plans, whether or not qualified within the
meaning of Section 401 (a) of the Internal Revenue Code of 1986, as may be
amended from time to time (the "Code"), as may be now or hereafter sponsored
or maintained for all employees of the Company, and participation on the same
terms and conditions as other executive officers in such other plan, program
or arrangement as may be now or hereafter sponsored or maintained for
executive officers of the Company;

           e. reimbursement for reasonable travel and other expenses incurred
by Executive in performing his obligations hereunder pursuant to the terms and
conditions of the Company's policy in respect thereto; and

           f. reasonable vacations, absences on account of temporary illness
and fringe benefits customarily enjoyed by employees or officers of the
Company under the terms and conditions of the Company's policy in respect
thereto.

                                      -2-
<PAGE>

        Nothing contained in this Agreement shall prevent the Board of
Directors from amending or otherwise altering the Plan, or any other plan,
program or arrangement so long as such amendment or alteration (i) is
accomplished pursuant to the terms thereof as in effect on the Effective Date
or on the date such is adopted, if later, and (ii) equitably affects all
employees, executive or otherwise, previously covered thereunder.

        4. Termination of Employment. This Agreement shall terminate upon the
           -------------------------
Expiration Date or upon the death of the Executive. The Company may terminate
this Agreement prior to the Expiration Date (and the Executive's employment
hereunder shall terminate) for "Disability" or "Cause". Termination of this
Agreement by the Company for any reason not set forth in the two preceding
sentences shall not be deemed a permitted termination and shall be deemed a
breach of this Agreement. In the event of any termination of this Agreement
prior to the Expiration Date, whether a permitted termination or otherwise,
the provisions of Section 5 of this Agreement shall determine the amount, if
any, of any compensation thereafter due the Executive in respect to such
termination.

           As used in this Agreement, the following terms shall have the
meanings set forth:

           a. Disability. If, as a result of the Executive's incapacity due to
              ----------
physical or mental illness, the Executive shall have been absent from his
duties with the Company on a full-time basis for six consecutive months, and
within thirty days after written notice of termination is given by the
Company, the Executive shall not have returned to the full-time daily
performance of his duties, the Executive shall be deemed to have experienced a
Disability and the Company may terminate the Executive's employment. The
Executive shall be entitled to leaves of absence from the Company in
accordance with the Company's policy generally applicable to executives for
illness or other temporary disabilities for a period or periods not exceeding
an aggregate of six months in any calendar year, and his compensation and
status as an employee hereunder shall continue during any such period or
periods.

        b. Cause. Termination by the Company of employment for "Cause" shall
           -----
mean termination upon:

           (1)   the willful and continued failure by the Executive to
substantially perform his duties with the Company (other than any such failure
resulting from his incapacity due to physical or mental illness), after a
written demand for substantial performance is delivered to the Executive by
the Board of Directors which specifically identifies the manner in which the
Board of Directors believes that the Executive has not substantially performed
his duties, and which failure has not been cured within thirty days after such
written demand; or

           (ii)  the willful and continued engaging by the Executive in conduct
which is demonstrated and materially injurious to the Company, monetarily or
otherwise; or

           (iii) the willful breach by the Executive of the Non-Competition
clause in Section 8, the Non-Solicitation clauses in Sections 9 and 10 or the
Confidentiality clause in Section 11 hereof.

                                      -3-
<PAGE>

        For purposes of this Subsection (b), no act, or failure to act, on the
Executive's part shall be considered "willful" unless done, or omitted to be
done, by the Executive in bad faith and without reasonable belief that such
action or omission was in the best interest of the Company. Notwithstanding
the foregoing, the Executive shall not be deemed to have been terminated for
Cause unless and until there shall have been delivered to him a copy of a
resolution duly adopted by the affirmative vote of at least 80% of the
directors then serving (after reasonable notice to the Executive and an
opportunity for the Executive, together with his counsel, to be heard before
the Board of Directors), finding that in the good faith opinion of the Board
of Directors the Executive was guilty of conduct set forth above in clauses
(i), (ii) or (iii) of the first sentence of this Subsection (b) and specifying
the particulars thereof in detail.

        c. Notice of Termination. Any purported termination by the Company
           ---------------------
shall be communicated by written Notice of Termination to the Executive in
accordance with Section 13 hereof. For purposes of this Agreement, a "Notice
of Termination" shall mean a notice which shall indicate the specific
termination, resignation or retirement provision in this Agreement relied upon
and shall set forth in reasonable detail the facts and circumstances claimed
to provide a basis for such termination, resignation or retirement under the
provision so indicated.

        d. Date of Termination, Etc. "Date of Termination" shall mean (i) if
           ------------------------
the Executive's employment is terminated for Disability, thirty days after
Notice of Termination is given (provided that the Executive shall not have
returned to the performance of the Executive's duties on a full-time daily
basis during such thirty-day period), and (ii) if the Executive's employment
is terminated for any other reason, the date specified in the Notice of
Termination (which shall not be less than thirty days nor more than sixty
days, from the date such Notice of Termination is given) and provided that
if within thirty days after any Notice of Termination is given the Executive
and the Executive has notified the Company that a dispute exists concerning
the termination, the Date of Termination shall be the date on which the
dispute is finally determined by mutual written agreement of the parties, by a
binding arbitration award, or by a final judgment, order or decree of a court
of competent jurisdiction (the time for appeal therefrom having expired and no
appeal having been perfected). Any party giving notice of a dispute shall
pursue the resolution of such dispute with reasonable diligence.
Notwithstanding the pendency of any such dispute, the Executive will be
entitled to indemnification under Section 7 hereof and the Company will
continue to pay the Executive his full compensation in effect when the notice
giving rise to the dispute was given (including, but not limited to, base
salary) and continue the Executive as a participant in all compensation,
employee benefit and insurance plans, programs and arrangements in which the
Executive was participating when the notice giving rise to the dispute was
given, until the dispute is finally resolved in accordance with this
Subsection (d).

        5. Compensation Upon Termination.
           -----------------------------

           a. Death. If the Executive's employment hereunder terminates by
              -----
reason of his death, the Company shall be obligated to pay to his surviving
widow, or to his legal representatives if he leaves no surviving widow or if
his surviving widow dies prior to fulfillment of the Company's obligations,
(i) the Executive's then current base salary for a twelve (12) month

                                      -4-
<PAGE>

period commencing on the first day of the month following the Executive's
death, or until the Expiration Date, whichever shall be the first to occur,
(ii) within 30 days after the Executive's death, a one time payment of
$100,000, and (iii) any benefits to which the Executive is entitled under any
insurance policies on the life of the Executive, under the Company's insurance
programs and other employee benefit plans, programs and arrangements then in
effect and under the Company's pension plan for salaried employees, if any. In
addition to the foregoing, the Company shall arrange to provide the
Executive's spouse and eligible dependents with and shall pay the cost or
premiums when due for health and accident insurance benefits substantially
similar to those which the Executive is receiving immediately prior to his
death.

        b. Disability. If the Executive's employment hereunder terminates by
           ----------
reason of his Disability, the Company shall (i) continue to pay to the
Executive, in accordance with the payroll practices of the Company in effect
prior to the Date of Termination, the Executive's then current base salary for
thirty-six (36) months after the Date of Termination, reduced by any benefits
to which the Executive may be entitled under any Company sponsored disability
income or income protection plan, policy or arrangement, the premiums for
which are paid by the Company, and (ii) for each of the three years after the
Date of Termination an amount equal to the highest annual bonus that the
Executive received in the three years prior to the Date of Termination,
payable each year in a lump sum at approximately the same time as annual
bonuses were paid by the Company in the year prior to the Date of Termination.
If the Executive dies prior to the date on which such additional amounts would
have ceased to be payable under this Subsection (b), the amount that would
have been payable by the Company had he lived shall continue to be paid by the
Company to his surviving widow, for a period of 12 months following the
Executive's death, at the same times and rates as it would have been payable
to him.

        c. Cause. If the Executive's employment hereunder is terminated by the
           -----
Company for Cause, the Company shall pay to the Executive his full base salary
through the Date of Termination at the rate in effect at the time Notice of
Termination is given and the Company shall have no further obligations to the
Executive under this Agreement.

        d. Voluntary Resignation or Retirement. In the event the Executive
           -----------------------------------
retires or resigns other than because of a material breach of this Agreement
by the Company, the Company shall pay to the Executive his full base salary
through the Date of Termination at the rate in effect at the time Notice of
Termination is given and, except as provided in Section 6, the Company shall
have no further obligations to the Executive under this Agreement.

        e. Other. If the Executive's employment hereunder is terminated (1) by
           -----
the Company other than for Cause or Disability, or (2) by the Executive
because of a material breach by the Company of this Agreement, then the
Executive shall be entitled to the benefits provided below:

           (i) the Company shall pay the Executive his full base salary
through the Date of Termination at the rate in effect at the time Notice of
Termination is given;

           (ii) in lieu of any further salary payments to the Executive for
periods subsequent to the Date of Termination, the Company shall pay as
severance pay to the Executive,

                                      -5-
<PAGE>

not later than the thirtieth day following the Date of Termination, a lump sum
severance payment equal to the Executive's full base salary for the then
remaining term of this Agreement (without regard to the date of such Notice of
Termination) at the rate then in effect, discounted to present value at a
discount rate of 7% per annum applied to each future payment from the time it
would have become payable;

           (iii) the Executive shall receive, not later than the thirtieth day
following the Date of Termination, that number of shares of the Corporation's
common stock with a value equal to the product of (i) the difference (to the
extent that such difference is a positive number) obtained by subtracting the
per share exercise price of each (1) Option and (2) SAR held by the Executive,
whether or not then fully exercisable, from the closing price of the Common
Stock (the "Closing Price") as reported on the National Association of
Securities Dealers Automatic Quotation/National Market System, or such similar
national quotation system or stock exchange on the Date of Termination (or if
not traded on the Date of Termination, the closing price on the preceding
business day on which the Common Stock traded), and ii) the total number of
Options and SARs held by the Executive provided, however, that the Executive
may elect to receive in lieu of stock an amount of cash equal to his federal
and state income tax liability with respect to amounts received pursuant to
this subsection (iii);

           (iv) the Company shall also pay directly as incurred or reimburse the
Executive, upon demand, all legal fees and expenses incurred by the Executive
in contesting or disputing any such termination or in seeking to obtain or
enforce any right or benefit provided by this Agreement or in connection with
any tax audit or proceeding to the extent attributable to the application of
Section 4999 of the Internal Revenue Code (the "Code") to any payment or
benefit provided hereunder;

           (v) for the remainder of the Executive's life, the Company shall
arrange to provide the Executive with and shall pay the cost or premiums when
due for disability and health-and-accident insurance benefits substantially
similar to those which the Executive is receiving immediately prior to the
Notice of Termination;

           (vi) the payments under this Subsection (e) are intended by the
parties to be due and payable under the circumstances of a termination for the
reasons set forth above whether or not such circumstances are preceded by a
change in control of the Company. If, notwithstanding the intentions of the
parties, it is asserted by any governmental agency, in any tax audit,
administrative proceeding or otherwise, that any payments provided under this
Section 5(e) (the "Severance Payments") are or will be subject to the tax (the
"Excise Tax") imposed by Section 4999 of the Code (or any successor provision
thereto) and/or that a federal income tax deduction for amounts paid as
Severance Payments will not be allowed to the Company for any year by reason
of Section 28OG of the Code (or any successor provision thereto), the
Executive may contest or refute such assertion with respect to the Excise Tax
in any appropriate forum (the "Executive's Contest") and the Company shall
diligently and vigorously contest or refute such assertion with respect to the
disallowance of such deduction in all administrative proceedings and in the
federal district court or the Tax Court, whichever shall have Jurisdiction
(the "Company's Contest"). The Executive's Contest and the Company's Contest
shall be conducted and presented

                                      -6-
<PAGE>

separately unless the Executive, in his discretion but with the consent of the
Company, joins in the Company's Contest. In any event, the Executive shall be
entitled to retain attorneys and other experts deemed necessary or appropriate
by the Executive to the proper presentation of the Executive's Contest and
shall not be compelled by the Company to compromise, settle or otherwise
terminate the Executive's Contest without his written consent thereto. The
Company and the Executive shall cooperate one with the other and each shall
provide to the other copies of all documents relevant to or useful in
connection with either the Executive's Contest or the Company's Contest as may
reasonably be requested by the other. The Executive shall attend any hearing,
deposition or other proceeding at which his attendance in person is material
to the Company's Contest. The Company shall cause the appropriate authorized
officer or officers of the Company to attend any hearing, deposition or other
matter at which the Company's appearance is requested by any party; and

           (vii) The payments provided for in this Subsection (e), shall be
made not later than the thirtieth day following the Date of Termination,
provided, however, that if the amounts of such payments cannot be finally
determined on or before such day, the Company shall pay to the Executive on
such day an estimate, as determined in good faith by the Company, of the
minimum amount of such payments and shall pay the remainder of such payments
(together with interest at the rate provided in Section 1274(b)(2)(B) of the
Code) as soon as the amount thereof can be determined but in no event later
than the sixtieth day after the Date of Termination. In the event that the
amount of the estimated payments exceeds the amount subsequently determined to
have been due, such excess shall constitute a loan by the Company to the
Executive payable on the fifth day after demand by the Company (together with
interest at the rate provided in Section 1274(b)(2)(B) of the Code).

        f. The Executive shall not be required to mitigate the amount of any
payment provided for in this Section 5 by seeking other employment or
otherwise, nor shall the amount of any payment provided for in this Section 5
be reduced by any compensation earned by the Executive as the result of
employment by another employer, or otherwise. Notwithstanding the preceding
sentence, benefits otherwise receivable by the Executive pursuant to Section
5(c)(v) above shall be reduced to the extent comparable benefits are actually
received by the Executive from the plan or plans of any subsequent employer
or from any program maintained by any governmental body not requiring
contribution by the Executive, and any such benefits actually received by the
Executive shall be reported to the Company.

        6. Retirement.
           ----------

        Nothing contained in this Agreement shall be deemed to limit the
Executive's right to receive vested benefits under the Company's retirement
policies and pension plan for salaried employees, if any, and to thereby
receive all benefits for which he is eligible under such plans and any other
plan, program or arrangement of the Company, all subject to and in accordance
with the terms of those plans.

                                      -7-
<PAGE>

        7. Indemnification.
           ---------------

           a. The Company shall indemnify and hold harmless to the full extent
not prohibited by law, as the same exists or may hereinafter be amended,
interpreted or implemented (but, in the case of any amendment, only to the
extent that such amendment permits the Company to provide broader
indemnification rights than the Company is permitted to provide prior to such
amendment), the Executive or his estate if made a party to, or threatened to
be made a party to, or is otherwise involved in (as a witness or otherwise)
any threatened, pending or completed action, suit, or proceeding, whether
civil, criminal, administrative or investigative and whether or not by or in
the right of the Company or otherwise (hereinafter, a "proceeding"), by reason
of the fact that he, or a person of whom he is the heir, executor, or
administrator, is or was a director, officer or controlling person (within the
meaning of the Securities Exchange Act of 1934, as amended) of the Company or
is or was serving at the request of the Company as a director, officer or
trustee of another Company or of a partnership, joint venture, trust or other
enterprise (including, without limitation, service with respect to employee
benefit plans), or where the basis of such proceeding is any alleged action or
failure to take any action by the Executive while acting in an official
capacity as a director, officer or controlling person of the Company or in any
other capacity on behalf of the Company, against all expenses, liability and
loss, including but not limited to attorneys' fees, judgments, fines, excise
taxes or penalties and amounts paid or to be paid in settlement whether with
or without court approval, actually incurred or paid by the Executive in
connection therewith.

           b. Notwithstanding the foregoing, and except as provided in Section
7(e) below, the Company shall indemnify the Executive seeking indemnification
in connection with a proceeding (or part thereof) initiated by the Executive
only if such proceeding (or part thereof) was authorized by the Board of
Directors of the Company.

           c. Subject to the limitation set forth above concerning proceedings
initiated by the Executive, the right to indemnification conferred in this
Section 7 shall be a contract right and shall include the right to be paid by
the Company the expenses incurred in defending any such proceeding (or part
thereof) or in enforcing his rights under this Section 7 in advance of the
final disposition thereof promptly after receipt by the Company of a request
therefor stating in reasonable detail the expenses incurred; provided,
however, that to the extent required by law, the payment of such expenses
incurred by the Executive in advance of the final disposition of a proceeding
shall be made only upon receipt of an undertaking, by or on behalf of the
Executive, to repay all amounts so advanced if and to the extent it shall
ultimately be determined by a court that he is not entitled to be indemnified
by the Company under this Section 7, or in the case of a criminal action, the
majority of the Board of Directors so determines that he is not entitled to be
indemnified by the Company, or otherwise.

           d. The right to indemnification and advancement of expenses
provided herein shall continue as to the Executive after he has ceased to be
employed by the Company or to serve in any of the other capacities described
herein, and shall inure to the benefit of his heirs, executors and
administrators.

                                      -8-
<PAGE>

           e. Company shall reimburse the Executive for the expenses
(including attorneys' fees and disbursements) incurred in successfully
prosecuting or defending any dispute related to his right to indemnification
hereunder.

           f. The right to indemnification and the payment of expenses
incurred in defending a proceeding in advance of a final disposition conferred
in this Section 7 shall not be deemed exclusive of any other rights to which
the Executive may be entitled under the articles of incorporation, any bylaw,
agreement, vote of shareholders, vote of directors Or otherwise, both as to
actions in his official capacity and as to actions in any other capacity while
holding that office.

        8. Non-Competition. During the term of this Agreement and, if and only
           ---------------
if the Executive's employment has been terminated by the Company for Cause,
and in no other case, for one (1) year after the Date of Termination, the
Executive shall refrain from competing with the Company or any subsidiary of
the Company except with the Company's prior written consent. The phrase
"refrain from competing with the Company or any subsidiary of the Company"
shall mean that the Executive will not engage, directly or indirectly
(including, by way of example only, as a principal, partner, venturer,
employee or agent) nor have any direct or indirect interest in any enterprise
(a "Competing Enterprise") which competes with the Company or any subsidiary
thereof by providing information technology consultants to clients on an
independent contractor basis. It is agreed that the foregoing provisions shall
not restrict the Executive from either (i) being a director of or having any
investments or other interests in an enterprise which is not a competing
enterprise, or (ii) having any investments in any competing enterprise the
stock of which is listed on a national securities exchange or traded publicly
over-the-counter so long as such investment does not give the Executive more
than five percent (5%) of the voting stock of such enterprise.

        9. Non-Solicitation of Customers and Suppliers. Executive agrees that
           -------------------------------------------
during his employment with the Company he shall not, directly or indirectly,
solicit the trade of, or trade with, any customer, prospective customer,
supplier, or prospective supplier of the Company for any business purpose
other than for the benefit of the Company. Executive further agrees that for
one (1) year following termination of his employment with the Company,
including without limitation termination by the Company for cause or without
cause, Executive shall not, directly or indirectly, solicit the trade of, or
trade with, any customers or suppliers, or prospective customers or suppliers,
of the Company except in instances where the Company has not solicited the
potential client in the past or where the services proposed to be offered by
the Executive are not then offered by the Company.

        10. Non-Solicitation of Employees. Executive agrees that, during his
            -----------------------------
employment with the Company and for one (1) year following termination of
Executive's employment with the Company, including without limitation
termination by the Company for cause or without cause, Executive shall not,
directly or indirectly, solicit or induce, or attempt to solicit or induce,
any employee of the Company to leave the Company for any reason whatsoever, or
hire any employee of the Company.

                                      -9-
<PAGE>

        11. Confidentiality. The Executive agrees:
            ---------------

            a. To keep secret all trade secret and proprietary information of
the Company and its subsidiaries and affiliates and not to disclose them to
anyone outside the Company or its subsidiaries and affiliates, either during
or for one year after his employment with the Company, except with the
Company's prior written consent or as required by law; and

            b. To deliver promptly to the Company on termination of
Executive's employment with the Company all memoranda, notes, records, reports
and other documents (and all copies thereof) with respect to any such trade

           (ii) This Agreement shall be binding on the successors and assigns
of the Company, and the Company shall require any successor (whether direct or

           (iii) indirect, by purchase, merger, consolidation or otherwise) to
all or substantially all of the business or assets of the Company, by
agreement in form and substance satisfactory to the Executive, expressly to
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform if no such succession had
taken place. As used in this Agreement, "Company" shall mean the Company as
defined in the preamble to this Agreement and any successor to its business
or assets which executes and delivers the agreement provided for in this
Subsection 14 (b) (ii) or which otherwise becomes bound by all the terms and
provisions of this Agreement by operation of law.

        c. This Agreement may be amended, modified, superseded, canceled,
renewed or extended and the terms or covenants hereof may be waived, only by a
written instrument executed by both of the parties hereto, or in the case of
a waiver, by the party waiving compliance. The failure of either party at any
time or times to require performance of any provisions hereof shall in no
manner affect the right at a later time to enforce such provisions
thereafter. No waiver by either party of the breach of any term or covenant
contained in this Agreement, whether by conduct or otherwise, in any one or
more instances, shall be deemed to be, or construed as, a further or
continuing waiver of any such breach or a waiver of the breach of any other
term or covenant contained in this Agreement.

        d. In the event any one or more of the covenants, terms or provisions
contained in this Agreement shall be invalid, illegal or unenforceable in any
respect, the validity of the remaining covenants, terms and provisions
contained herein shall be in no way affected, prejudiced or disturbed thereby.

        e. This Agreement is personal in nature and neither of the parties
hereto shall, without the consent of the other, assign or transfer this
Agreement or any rights or obligations hereunder, except as provided in
Subsection 14(b) above. Without limiting the foregoing, the Executive's right
to receive payments hereunder shall not be assignable or transferable, whether
by pledge, creation of a security interest or otherwise, other than a
transfer by his will or by the laws of descent or distribution, and in the
event of any attempted assignment or transfer contrary to this Subsection
14(e) the Company shall have no liability to pay any amount so attempted to be
assigned or transferred; provided, however, that the Executive may ask the
Company to consent to any assignment of any payments due after the termination
of his employment and the Company shall not unreasonably withhold such
consent.

        IN WITNESS WHEREOF, the parties have caused this Agreement to be
executed and delivered as of the date first above written.
