                SECTION B--SUPPLIES OR SERVICES AND PRICES/COSTS

B.1 Descriptions/Specifications

Supplies/Services: The contractor will provide Voice, Data, Video and ADP
Integration Support Services for any federal government agency or GSA customer,
nationwide. The contractor is also responsible for providing Federal
Information Processing (FIP) equipment in addition to the integration support
services.

Performance will be authorized by specific delivery/task orders.

B.2 Estimated Quantity of Services/Materials: The Government can not predict
the precise quantity of services ordered under this contract, therefore, the
quantity of annual hours shown in section B are estimates only. The total
(options included) estimated material costs of $35,000,000 in Section B shall
not be exceeded during the life of this contract.

B.3 Pricing of Task/Delivery Orders: Orders shall be priced on the basis of
fixed loaded hourly rates contained in Section B. These rates are fixed for the
term of the contract, including all option  years. The actual amounts of labor
hours to be used per delivery/task order or mod will be negotiated between the
contractor and the Government (GSA).

B.4 General and Administrative Rates and Material Handling Fee: From the date of
award through DCAA approval of a provisional M&S rate, the contractor is
entitled to bill a G&A rate of 10.06% with a fee of 1% on all material costs
that are associated with individual task/delivery orders. In 1996, TCS will
implement a provisional M&S rate which will replace the application of G&A with
fee on material. This rate will be capped at 8.0% and will cover all remaining
time on the contract. Once this rate is approved by the DCAA, it will be
retroactive to 1/1/96 and a refund will be given to all previous customers and
a credit given to active task customers on future invoices.

I.4   52.203-10 Price or Fee Adjustment for Illegal or Improper Activity
      (SEP 1990)

   (a) The Government, at its election, may reduce the price of a fixed price
type contract or contract modification and the total cost and fee under a cost
type contract or contract modification by the amount of profit or fee determined
as set forth in paragraph (b) of this clause if the head of the contract
activity or his or her designee determines that there was a violation of
subsection 27(a) of the Office of Federal Procurement Policy Act, as amended (41
U.S.C. 423), as implemented by the FAR. In the case of a contract modification,
the fee subject to reduction is the fee specified in the particular contract
modification at the time of execution, except as provided in subparagraph (b)
(5) of this clause.

    (b) The price or fee reduction referred to in paragraph (a) of this clause
shall be:

         (1)  For cost plus fixed fee contracts, the amount of the fee specified
              in the contract at time of award;

         (2)  For cost plus incentive fee contracts, the target fee specified in
              the contract at the time of award, notwithstanding any minimum fee
              or "fee floor" specified in the contract;

         (3)  For cost plus award fee contracts-

              (i)  The base fee established in the contract at the time of
                   contract award.

              (ii)  If no base fee is specified in the contract, 30 percent of
                    the amount of each award fee otherwise payable to the
                    Contractor for each award fee evaluation period or at each
                    award fee determination point.

         (4)  For fixed price incentive contracts, the Government may-

                                     I-8
<PAGE>   61
              (i)   Reduce the contract target price and contract target profit
                    both by an amount equal to the initial target profit
                    specified in the contract at the time of the contract award;
                    or

              (ii)  If an immediate adjustment to the contract target price and
                    the contract target profit would have a significant adverse
                    impact on the incentive price revision relationship under
                    the contract, or adversely affect the contract financing
                    provisions, the Contracting Officer may defer such
                    adjustment until the establishment of the total final price
                    of the contract. The total final price established in
                    accordance with the incentive price revision provisions of
                    the contract shall be reduced by an amount equal to the
                    initial target profit specified in the contract at the time
                    of contract award and such reduced price shall be the total
                    final contract price.

          (5) For firm fixed price contracts or contract modifications, by 10
              percent of the initial contract price; 10 percent of the contract
              modification price; or a profit amount determined by the
              Contracting Officer from records or documents in existence prior
              to the date of the contract award or modification.

    (c) The Government may, at its election, reduce a prime contractor's price
or fee in accordance with the procedures in paragraph (b) of this clause for
violations of the Act by its subcontractors by an amount not to exceed the
amount of profit or fee reflected in the subcontract at the time the subcontract
was first definitively priced.

   (d) In addition to the remedies in paragraphs (a) and (c) of this clause, the
Government may terminate this contract for default. The rights and remedies of
the Government specified herein are not exclusive, and are in addition to any
other rights and remedies provided by law or under this contract.

                                   (3) Capability presentations by persons
seeking awards from an agency pursuant to the provisions of the Small Business
Act, as amended by Public Law 95-507 and subsequent amendments.

                            (e) Only those services expressly authorized by
subdivision (b) (3) (i) (A) of this clause are permitted under this clause.

                     (ii) Professional and technical services.

                            (a) The prohibition on the use of appropriated
funds, in subparagraph (b) (1) of this clause, does not apply in the case of-

                                   (1) A payment of reasonable compensation made
       to an officer or employee of a person requesting or receiving a covered
       Federal action or an extension, continuation, renewal, amendment, or
       modification of a covered Federal action, if payment is for professional
       or technical services rendered directly in the preparation, submission,
       or negotiation of any bid, proposal, or application for that Federal
       action or for meeting requirements imposed by or pursuant to law as a
       condition for receiving that Federal action.

                                   (2) Any reasonable payment to a person, other
       than an officer or employee of a person requesting or receiving a
       covered Federal action or an extension, continuation, renewal, amendment,
       or modification of a covered Federal action if the payment is for
       professional or technical services rendered directly in the preparation,
       submission, or negotiation of any bid, proposal, or application for that
       Federal action or for meeting requirements imposed by or pursuant to law
       as a condition for receiving that Federal action. Persons other than
       officers or employees of a person requesting or receiving a

                                     I-13
<PAGE>   66
covered Federal action include consultants and trade associations.

                            (b) For purposes of subdivision (b) (3) (ii) (A) of
this clause, "professional and technical services" shall be limited to advice
and analysis directly applying any professional or technical discipline. For
example, drafting of a legal document accompanying a bid or proposal by a lawyer
is allowable. Similarly, technical advice provided by an engineer on the
performance or operational capability of a piece of equipment rendered directly
in the negotiation of a contract is allowable. However, communications with the
intent to influence made by a professional (such as a licensed lawyer) or a
technical person (such as a licensed accountant) are not allowable under this
section unless they provide advice and analysis directly applying their
professional or technical expertise and unless the advice or analysis is
rendered directly and solely in the preparation, submission or negotiation of a
covered Federal action. Thus, for example, communications with the intent to
influence made by a lawyer that do not provide legal advice or analysis directly
and solely related to the legal aspects of his or her client's proposal, but
generally advocate one proposal over another are not allowable under this
section because the lawyer is not providing professional legal services.
Similarly, communications with the intent to influence made by an engineer
providing an engineering analysis prior to the preparation or submission of a
bid or proposal are not allowable under this section since the engineer is
providing technical services but not directly in the preparation, submission or
negotiation of a covered Federal action.

                            (c) Requirements imposed by or pursuant to law as a
condition for receiving a covered Federal award include those required by law or
regulation and any other requirements in the actual award documents.

                            (d) Only those services expressly authorized by
subdivisions (b) (3) (ii) (A) (1) and (2) of this clause are permitted under
this clause.

                            (e) The reporting requirements of FAR 3.803(a) shall
not apply with respect to payments of reasonable compensation made to regularly
employed officers or employees of a person.

       (c) Disclosure

            (1) The Contractor who requests or receives from an agency a Federal
contract shall file with that agency a disclosure form, OMB standard form LLL,
Disclosure of Lobbying Activities, if such person has made or has agreed to make
any

                                     I-14
<PAGE>   67
payment using nonappropriated funds (to include profits from any covered Federal
action), which would be prohibited under subparagraph (b)(1) of this clause, if
paid for with appropriated funds.

            (2) The Contractor shall file a disclosure form at the end of each
calendar quarter in which there occurs any event that materially affects the
accuracy of the information contained in any disclosure form previously filed by
such person under subparagraph (c)(1) of this clause. An event that materially
affects the accuracy of the information reported includes--

                  (i) A cumulative increase of $25,000. or more in the amount
paid or expected to be paid for influencing or attempting to influence a covered
Federal action; or

                  (ii) A change in the person(s) or individual(s) influencing or
attempting to influence a covered Federal action; or

                  (iii) A change in the officer(s), employee(s), or Member(s)
contacted to influence or attempt to influence a covered Federal action.

            (3) The Contractor shall require the submittal of a certification,
and if required, a disclosure form by any person who requests or receives any
subcontract exceeding $100,000 under the Federal contract.

            (4) All subcontractor disclosure dorms (but not certifications)
shall be forwarded from tier to tier until received by the prime Contractor. The
prime Contractor shall submit all disclosures to the Contracting Officer at the
end of the calendar quarter in which the disclosure form is submitted by the
subcontractor. Each subcontractor certification shall be retained in the
subcontract file of the awarding Contractor.

      (d) Agreement. The Contractor agrees not to make any payment prohibited by
this clause.

      (e) Penalties.

            (1) Any person who makes an expenditure prohibited under paragraph
(a) of this clause or who fails to file or amend the disclosure form to be filed
or amended by paragraph (b) of this clause shall be subject to civil penalties
as provided for by 31 U.S.C. 1352. An imposition of a civil penalty does prevent
the Government from seeking any other remedy that may be applicable.

                                     I-15
<PAGE>   68
             (2) Contractors may rely without liability on the representation
made by their subcontractors in the certification and disclosure form.

        (f) Cost Allowability. Nothing in this clause makes allowable or
reasonable any costs which would otherwise be unallowable or unreasonable.
Conversely, costs made specifically unallowable by the requirements in this
clause will not be made allowable under any other provision.

subcontracts or purchase orders for public utility services at rates established
for uniform applicability to the general public.

I.14  552.228-75 WORKMEN'S COMPENSATION LAWS (APR 1984)

  The Act of June 25, 1936, 49 Stat. 1938 (40 U.S.C. 290) authorizes the
constituted authority of the several States to apply their workmen's
compensation laws to all lands and premises owned or held by the United States.

I.15  552.232-23 ASSIGNMENT OF CLAIMS (GSA ALTERNATE) (MAY 1989)

  Because this is a requirements or indefinite quantity contract under which
more than one agency may place orders, paragraph (a) of the Assignment of Claims
clause prescribed in FAR 52.232-23 is inapplicable and the following is
substituted therefore:

  In order to prevent confusion and delay in making payment, no claim(s) for
amounts due or to become due under this contract, shall be assigned by the
Contractor; but it shall be permissible for the Contractor to assign separately
to a bank, trust company, or other financial institution, including any Federal
lending agency, under the provisions of the Assignment of Claims Act, as
amended, 31 U.S.C. 3727, 41 U.S.C. 15 (hereinafter referred to as "the Act"),
all amounts due or to become due under any delivery order amounting to $1,000 or
more issued by any Government agency under this contract. Any such assignment
shall be effective only if and when the assignee files written notice of the
assignment together with a true copy of the instrument of assignment with the
contracting officer issuing the delivery order and the finance office designated
in the delivery order to make payment. Unless otherwise stated in the delivery
order, payments to an assignee of any amounts due or to become due under any
delivery order assigned may, to the extent specified in the Act, be subject to
reduction or set-off.

I.16  552.232-70 PAYMENTS BY ELECTRONIC FUNDS TRANSFER (APR 1989)

  The submission of a designation of financial institution for receipt of
electronic funds transfer payments in the "Electronic Funds Transfer Payment
Methods" clause (FAR 52.232-28) shall be as follows: The Contractor shall submit
its designation of a financial institution for receipt of electronic funds
transfer payments with each invoice requesting payment of $25,000 or more
(exclusive of any discount for prompt payment). The information

                                     I-22
<PAGE>   75
for electronic funds transfer is not required by the Department of Defense, the
United States Postal Service, or the Tennessee Valley Authority. Information
required for electronic funds transfer payments shall be furnished to the
Veterans Administration in accordance with instructions provided by that agency.
Other agencies and departments thereof may waive the requirement for designation
of a financial institution for receipt of electronic funds transfer payments and
for submission of information required to make such payments by including a
notice on delivery orders or otherwise notifying the Contractor.

I.17  552.232-72 INVOICE REQUIREMENTS (APR 1989)

  (a) Invoices shall be submitted in an original only, unless otherwise

            clause of this contract.

I.18  552.232-77 AVAILABILITY OF FUNDS (JUL 1984)

  The authorization of performance of work under this contract during the
initial contract period and any option period(s) is contingent upon the
appropriation of funds to procure this service. If the contract is awarded,
extended or option(s) exercised, the Government's obligation beyond the end of
the fiscal year (September 30), in which the award or extension is made or
option(s) exercised, is contingent upon the availability of funds from which
payment for the contract services can be made. No legal liability on the part of
the Government for payment of any money beyond the end of each fiscal year
(September 30) shall arise unless or until funds are made available to the
Contracting Officer for this procurement and written notice of such availability
is given to the contractor.

I.19  552.236-75 USE OF PREMISES (APR 1984)

  (a) If the premises are occupied, the contractor, his subcontractor, and their
employees shall comply with the regulations governing access to, operation of,
and conduct while in or on the premises and shall perform the work required
under this contract in such a manner as not to unreasonably interrupt or
interfere with the conduct of Government business.

  (b) Any requests received by the contractor from occupants of existing
buildings to change the sequence of work shall be referred to the Contracting
Officer for determination.

  (c) If the premises are occupied, the contractor, his subcontractor and their
employees shall not have access to or be admitted into any building outside the
scope of this contract except with official permission.

I.20  552.252-6 AUTHORIZED DEVIATIONS OR VARIATIONS IN CLAUSES (DEVIATION FAR
52.252-6) (JUL 1985)

  (a) The use in this solicitation or contact of any Federal Acquisition
Regulation (48 CFR Chapter 1) clause with an authorized deviation or variation
is indicated by the addition of "(DEVIATION)" or "(VARIATION)" after the date
of the clause, if the clause is not published in the General Services
Administration Acquisition Regulation (48 CFR Chapter 5). The use in this
solicitation of any Federal Acquisition Regulation (FAR) clause with an
authorized deviation or variation that is published in the General Services
Administration Acquisition Regulation is indicated by the addition of
"(DEVIATION (FAR clause no.))" or "(VARIATION (FAR clause no.)" after the date
of the clause.

                                     I-24
<PAGE>   77
   (b) The use in this solicitation of any General Services Administration
Acquisition Regulation clause with an authorized deviation or variation is
indicated by the addition of "(DEVIATION)" or "(VARIATION)" after the date of
the clause.

   (c) Changes in wording of clauses that are prescribed for use on a
"substantially the same as" basis are not considered deviations. Therefore, when
such clauses are not worded exactly the same as the FAR or GSAR clause, they are
identified by the word "(VARIATION)".

I.21  201-39.5202-3 PROCUREMENT AUTHORITY (OCT 1990 FIRMR)

   This acquisition is being conducted under DOE's exclusive procurement
authority for FIP resources.

   The specific GSA DPA case number is not applicable.

I.22  201-39.5202-5 PRIVACY OR SECURITY SAFEGUARDS (FIRMR) (OCT 1990)

   (a) The details of any safeguards the contractor may design or develop under
this contract are the property of the Government and shall not be published or
disclosed in any manner without the Contracting Officer's express written
consent.

   (b) The details of any safeguards that may be revealed to the contractor by
the Government in the course of performance under this contract shall not be
published or disclosed in any manner without the Contracting Officer's express
written consent.

   (c) The Government shall be afforded full, free, and uninhibited access to
all facilities, installations, technical capabilities, operations,
documentation, records, and data bases for the purpose of carrying out a
program of inspection to ensure continued efficiency of safeguards against
threats and hazards to data security, integrity, and confidentiality.

   (d) If new or unanticipated threats or hazards are discovered by either the
Government or the contractor, or if existing safeguards have ceased to function,
the discoverer shall immediately bring the situation to the attention of the
other party. Mutual agree shall then be reached on changes or corrections to
existing safeguards or institution of new safeguards, with final determination
of appropriateness being made by the Government. The Government's liability is
limited to an equitable adjustment of cost for such changes or corrections, and
the Government shall not be liable for claims of loss of business, damage to
reputation, or damages of any other kind

                                     I-25
<PAGE>   78

arising from discovery of new or unanticipated threats or hazards, or any
public or private disclosure thereof.

I.23  201-39.5202-6 WARRANTY EXCLUSION AND LIMITATION OF DAMAGES (FIRMR) (OCT

   Except as expressly set forth in writing in this agreement and except for the
implied warranty of merchantability, there are no warranties expressed or
implied.

In no event will the Contractor be liable to the Government for consequential
damages as defined in the Uniform Commercial Code, section 2-715, in effect in
the District of Columbia as of January 1,1973, i.e.,-

   Consequential damages resulting from the seller's breach include-

   (a) Any loss resulting from general or particular requirements and needs of
which the seller at the time of contracting had reason to know and which could
not reasonably be prevented by cover or otherwise; and

   (b) Injury to person or property proximately resulting from any breach of
warranty.

I.24   OPTION TO EXTEND THE TERM OF THE CONTRACT

The Government may extend the term of this contract at the prices identified in
Section B of any resultant contract.

The Contracting Officer shall give the Contractor a preliminary written notice
of its intent to extend at least 60 days prior to the contract's expiration
date. Such preliminary written notice does not commit the Government to extend
the term. If the Government exercises this option to extend the term of the
contract, such extension shall be provided by contract modification on or before
the expiration date. If the government exercises this option for extension of
the contract term, the extended contract shall be deemed to include this option
provision. The total duration of this contract, including exercise of any option
under this clause shall not extend beyond (3) years after the date of contract
award.

After the last paragraph under this part, the following new paragraphs are

G.7 Payment Of Invoices

Payments of invoices are based on hours worked by the contractor and the
Government's determination that satisfactory services were provided. In
addition, the contractor will be responsible for the certification that labor
charges are accurate. The Government will pay only for hours authorized and
worked.

Payments of invoices for ODCs (materials and supplies) will be based on
acceptance by the Government of such materials and supplies. The Government
will only pay for materials and supplies that meet the specified requirements
and commercially acceptable standards of quality.

If the supplies or services are rejected for failure to conform to the
technical requirements of the contract, or for damage in transit or otherwise,
the provisions in paragraph a. above of this clause will apply to the new
delivery of replacement supplies.

Payments to the contractor will not be made for temporary work stoppage due to
circumstances beyond the control of the agency such as acts of God, inclement
weather, power outages, etc., and results thereof and/or temporary closing of
facilities at which contractor personnel are performing; this may, however, be
justification for excusable delays.

Overtime is defined as any work performed in excess of forty (40) hours per
week when a contractor employee works a non-alternate work schedule. If an
alternate work schedule is required, and approved by the Government, overtime
is defined as any work performed in excess of eighty (80) hours biweekly.
Overtime hours are not allowed until authorized in the task order and approved
in advance by the client representative and the GSA COTR through the ACO.
Overtime will not be granted to compensate for shortcomings in contractor
performance. The contractor will not be reimbursed by the Government for
overtime work except when authorized by the ACO.

Invoices for final payment will be so identified and submitted within 120 days
after task completion. No further charges shall be billed. A copy of GSA's
written acceptance of task completion, when applicable, shall be attached. Work
associated with foreign orders will entirely be paid for with U.S. Funds.

G.8 Travel And Per Diem

The contractor will be reimbursed by the Government for travel and per diem
expenses incurred by the contractor's task order personnel when such travel is
specifically authorized in the task order. Travel and per diem payments are
intended as reimbursement to contractor employees and are not subject to
profit, deduction, or set-aside by the contractor.

G.8.1 Local Travel

Reimbursement will not be allowed for travel within a fifty (50) mile radius of
the employee's regular duty station unless the contractor employee is on
temporary assignment. The contractor will not be reimbursed for travel of the
contractor's employees to and from their residence to their assigned regular
duty station as defined in a task order, nor for travel necessitated by a task
order unless the travel consists of trips to areas outside a fifty (50) mile
radius from their regular duty station.

G.8.2 Temporary Assignments

Any task order requiring on-site assignment of the contractor's personnel at
locations away from the employee's regular duty station for less than three (3)
months will be considered a temporary assignment. Travel and per diem expenses
associated with Government-approved temporary assignments may be billed to the
Government. On task orders of this nature, reimbursable travel and per diem
expenses will not exceed the time or cost of travel as mutually agreed upon by
the contractor Program Manager and the ACO.

G.8.3 Permanent Assignments

Any task or series of tasks requiring continuous, on-site assignment of
contractor personnel for three (3) months or longer will be considered a
permanent assignment. The contractor may, at its discretion, accept assignments
of less than three (3) months under permanent assignment terms. No relocation,
travel, per diem expenses or travel time will be allowed by the Government for
placing contractor personnel at permanent assignments. The Government will not
pay the cost for relocation of contractor personnel.

G.8.4 Foreign Assignments

Foreign assignments will be for temporary duty only. Post differential, travel,
allowance and/or per diem for contractor employees assigned to duty outside the
United States will be at the rate prescribed for GSA Government employees. The
contractor will be responsible for obtaining passports, visas, and the like on
its own.

H.6 Organizational Conflict of Interest/Limits on Future Contracting

The General Services Administration and any customer under this contract will
not consider the contractor, its successor-in-interest, assignee, or affiliates
as a prime source of supply for, or allow it to be a subcontractor or
consultant to a supplier for any competitive procurements for which the
contractor provides technical support services/analyses/system design and
evaluation or other types of assistance.

To prevent unfair competitive advantage in a competitive procurement, the
contractor agrees that, until award of a contract by GSA or customer agency for
any competitive procurements for which the contractor performs a service under
this contract, it shall agree to do the following:

-   not disclose any information concerning the work under this contract,
    including technology developed or findings and conclusions rendered by
    the contractor in performing work under this contract, to any prospective
    offeror

-   not render any services of any kind related to such competitive
    procurements thereof to any such prospective offeror(s).

If under this contract, the contractor prepares or assists in the development
of a Statement Of Work or Operations Document to be used by the Government in a
competitive procurement, the contractor, it successor-in-interest, assignee or
affiliates will not be allowed to be the prime source of supply nor be a
subcontractor or consultant for the competitive procurement.

The restrictions stated above will be in effect for a period of two years from
the performance completion date of this contract or any task order issued
thereunder. At any time, the Government may modify, or waive entirely, the
restrictions outlined above if it deems necessary.

Request For Additional Funds on the New Boiler Control Valves.
At the time this work was quoted an incorrect model number was given by the OEM
for the Copes-Vulcan feedwater valve. After TCS provided a purchase order, the
subcontractor checked the existing valve against the quote and discovered the
error. This change reflects a $5,165.61 increase in material and labor charges
bringing the Grand Total to 1$14,095.64.

LIMITATION OF FUNDS - LABOR HOUR CONTRACT

       (a) The parties estimate that performance of this contract will not cost
the Government more than (1) the estimated cost specified in the task order. The
contractor agrees to use its best efforts to perform the work specified in the
task order and all obligations under this contract within the estimated cost.

       (b) The task order specifies the amount presently available for payment
by the Government and allotted to this contract, the items covered, and the
period of performance it is estimated the allotted amount will cover. The
parties contemplate that the Government will allot additional funds
incrementally to the contract up to the full estimated cost to the Government
specified in the task order. The contractor agrees to perform, or have
performed, work on the contract up to the point at which the total amount paid
and payable by the Government under the contract approximates but does not
exceed the total amount actually allotted by the Government to the contract.

       (c) The Contractor shall notify the Contracting Officer in writing
whenever it has reason to believe that the costs it expects to incur under this
contract in the next 60 days, when added to all costs previously incurred, will
exceed 75 percent of the total amount so far allotted to the contract by the
Government. The notice shall state the estimated amount of additional funds
required to continue performance for the period specified in the task order.

       (d) Sixty days before the end of the period specified in the task order,
the Contractor shall notify the Contracting Officer in writing of the estimated
amount of additional funds, if any, required to continue timely performance
under the contract or for any further period specified in the task order or
otherwise agreed upon, and when funds will be required.

       (e) If, after notification, additional funds are not allotted by the end
of the period specified in the task order or another agreed-upon date, upon the
Contractor's written request the Contracting Officer will terminate this
contract on that date in accordance with the provisions of the Termination
clause of this contract. If the Contractor estimates that the funds available
will allow it to continue to discharge its obligations beyond that date, it may
specify a later date in its request, and the Contracting Officer may terminate
this contract on that later date.

       (f) Except as required by other provisions of this contract, specifically
citing and stated to be an exception to this clause -

              (1) The Government is not obligated to reimburse the Contractor
for costs incurred in excess of the total amount allotted by the Government to
this contract; and

              (2) The Contractor is not obligated to continue performance under
this contract (including actions under the Termination clause of this contract)
or otherwise incur costs in excess of the amount then allotted to the contract
by the Government until the Contracting Officer notifies the Contractor in
writing that the amount allotted by the Government has been increased and
specifies an increased amount, which shall then constitute the total amount
allotted by the Government to this contract.

       (g) No notice, communication, or representation in any form other than
that specified in subparagraph (f)(2) above, or from any person other than the
Contracting Officer, shall affect the amount allotted by the Government to this
contract. In the absence of the specified notice, the Government is not
obligated to reimburse the Contractor for any costs in excess of the total
amount allotted by the Government to this contract, whether incurred during the
course of the contract or as a result of termination.

<PAGE>   88

Page 4 of 4 pages

       (h) When and to the extent that the amount allotted by the Government to
the contract is increased, any costs the Contractor incurs before the increase
that are in excess of the amount previously allotted by the Government shall be
allowable to the same extent as if incurred afterward, unless the Contracting
Officer issues a termination or other notice and directs that the increase is
solely to cover termination or other specified expenses.

       (I) Change orders shall not be considered an authorization to exceed the
amount allotted by the Government specified in the task order, unless they
contain a statement increasing the amount allotted.

       (j) Nothing in this clause shall affect the right of the Government to
terminate this contract. If this contract is terminated, the Government and the
Contractor shall negotiate an equitable distribution of all property produced or
purchased under the contract, based upon the share of costs incurred by each.

                  LIMITATION OF LIABILITY - INCREMENTAL FUNDING

This task order is incrementally funded and the amount currently available for
payment herunder is limited to $710,900.47 Subject to the provisions of the
clause entitled "Limitation of Funds - Labor Hour Contract", no legal liability
on the part of the Government for payment in excess of $710,900.47 shall arise
unless additional funds are made available and are incorporated as a
modification to this task order.

LIMITATION OF FUNDS - LABOR HOUR CONTRACT
---------- -- -----   ----- ---- --------

       (a) The parties estimate that performance of this contract will not cost
the Government more than the estimated cost specified in the task order. The
contractor agrees to use its best efforts to perform the work specified in the
task order and all obligations under this contract within the estimated cost.

       (b) The task order specifies the amount presently available for payment
by the Government and allotted to this contract, the items covered, and the
period of performance it is estimated the allotted amount will cover. The
parties contemplate that the Government will allot additional finds
incrementally to the contract up to the full estimated cost to the Government
specified in the task order. The contractor agrees to perform, or have
performed, work on the contract up to the point at which the total amount paid
and payable by the Government under the contract approximates but does not
exceed the total amount actually allotted by the Government to the contract.

       (c) The Contractor shall notify the Contracting Officer in writing
whenever it has reason to believe that the costs it expects to incur under this
contract in the next 50 days, when added to all costs previously incurred, will
exceed 75 percent of the total amount so far allotted to the contract by the
Government. The notice shall state the estimated amount of additional finds
required to continue performance for the period specified in the task order.

       (d) Sixty days before the end of the period specified in the task order,
the Contractor shall notify the Contracting Officer in writing of the estimated
amount of additional finds, if any, required to continue timely performance
under the contract or for any further period specified in the task order or
otherwise agreed upon, and when funds will be required.

       (e) If, after notification, additional funds are not allotted by the end
of the period specified in the task order or another agreed-upon date, upon the
Contractor's written request the Contracting Officer will terminate this
contract on that date in accordance with the provisions of the Termination
clause of this contract. If the Contractor estimates that the funds available
will allow it to continue to discharge its obligations beyond that date, it may
specify a later date in its request and the Contracting Officer may terminate
this contract on that later date.

       (f) Except as required by other provisions of this contract, specifically
citing and stated to be an exception to this clause -

              (1) The Government is not obligated to reimburse the Contractor
for costs incurred in excess of the total amount allotted by the Government to
this contract; and

              (2) The Contractor is not obligated to continue performance under
this contract (including actions under the Termination clause of this contract)
or otherwise incur costs in excess of the amount then allotted to the contract
by the Government until the Contracting Officer notifies the Contractor in
writing that the amount allotted by the Government has been increased and
specifies an increased amount, which shall then constitute the total amount
allotted by the Government to this contract.

       (g) No notice, communication, or representation in any form other than
that specified in subparagraph (f)(2) above, or from any person other than the
Contracting Officer, shall affect the amount allotted by the Government to this
contract. In the absence of the specified notice, the Government is not
obligated to reimburse the Contractor for any costs in excess of the total
amount allotted by the Government to this contract, whether incurred during the
course of the contract or as a result of termination.

<PAGE>   101

       (h) When and to the extent that the amount allotted by the Government to
the contract is increased, any costs the Contractor incurs before the increase
that are in excess of the amount previously allotted by the Government shall be
allowable to the same extent as if incurred afterward, unless the Contracting
Officer issues a termination or other notice and directs that the increase is
solely to cover termination or other specified expenses.

       (i) Change orders shall not be considered an authorization to exceed the
amount allotted by the Government specified in the task order, unless they
contain a statement increasing the amount allotted.

       (j) Nothing in this clause shall affect the right of the Government to
terminate this contract. If this contract is terminated, the Government and the
Contractor shall negotiate an equitable distribution of all property produced or
purchased under the contract, based upon the share of costs incurred by each.

                  LIMITATION OF LIABILITY - INCREMENTAL FUNDING
                  ---------------------------------------------

This task order is incrementally funded and the amount currently available for
payment hereunder is limited to $ 476,190.48. Subject to the provisions of the
clause entitled "Limitation of Funds - Labor Hour Contract", no legal liability
on the part of the Government for payment in excess of $ 476,190.48 shall arise
unless additional funds are made available and are incorporated as a
modification to this task order.
