Item 2.  Acquisition or Disposition of Assets

        On August 11, 1998, the Company, through its wholly owned subsidiary
MCTI Acquisition Corporation ("MCTI Acquisition"), acquired four affiliated,
privately held companies for cash. MCTI Acquisition purchased all the
outstanding stock of APCOM Inc. and Celerity Systems Inc., and the assets and
certain liabilities of Acceleration Systems, Inc. and Digital Telcom, Inc. for
approximately $16 million. The acquisition is being treated as a purchase for
accounting purposes. The Company obtained financing from NationsBank, N.A. to
finance the transaction. In conjunction with such financing, the Company
obtained a new line of credit facility from NationsBank, N.A. for $10 million
payable on October 31, 2000. The Company repaid the current borrowings under its
existing revolving line of credit facility totaling $4.5 million with the amount
available under this new line of credit. Operations of the companies will be run
in conjunction with those of the Company's wholly owned subsidiary, Microdyne
Communications Technologies Incorporated (MCTI) located in Ocala, Florida.

and in consideration for the sale by the Sellers to the Purchaser of the
Purchased Stock, the Purchased Options, the Purchased Loan Accounts, and the
Purchased Assets, the Purchaser shall, subject to the conditions and at the time
set forth in Section 2.06, pay to the Sellers an additional and contingent

earned and payable pursuant to Section 2.06, shall be part of the Purchase
Price. The Purchase Price other than the Earn-Out Amount is payable in the
manner provided in Sections 2.03 and 2.04 and the Earn-Out Amount, if earned and

         2.03 CLOSINGS.

         (a) The closing (the "Closing") for the purchase and sale contemplated

10:00 A.M. local time, on August 11, 1998 or such other date as the Purchaser
and the Sellers' Representative shall mutually agree (the date and time of the
Closing are herein referred to as the "Closing Date").

         (b) At the Closing:

                  (i) Purchaser will pay an aggregate of Thirteen Million Nine
         Hundred Thousand Dollars ($13,900,000) of the Purchase Price to the
         Sellers by wire transfer of immediately available funds to such account
         as each Seller may reasonably direct by written notice delivered to
         Purchaser by such Seller at least three (3) Business Days before the
         Closing Date, payable to each Seller in the amount obtained by
         multiplying $13,900,000 by the percentage set forth opposite such
         Seller's name 


                                       12
<PAGE>   18
         in Section 2.03(b) of the Disclosure Schedule (the "Shareholder
         Percentage"); provided, however, that with respect to any such payment
         to any Individual Seller which would constitute actual or deemed
         compensation to such Individual Seller in connection with such
         Individual Seller's employment with a Company or with respect to which
         withholding is otherwise reflected in Section 2.03(b) of the Disclosure
         Schedules, the Purchaser shall withhold from such payment all
         withholding required in connection therewith under applicable federal
         and state Tax or other relevant Laws, and such withheld amount shall be
         deemed for all purposes hereunder to have been paid to such Individual
         Seller. Any amounts so withheld by the Purchaser shall be paid by the
         Purchaser to the Target Companies, as applicable. In addition, of the
         amount of the Purchase Price payable to Mr. Timmer on the Closing Date
         as reflected in in Section 2.03(a) of the Disclosure Schedule, Mr.
         Timmer hereby authorizes the Purchaser to pay to Mr. Gallupe on his
         behalf, and on the Closing Date the Purchaser shall pay to Mr. Gallupe
         on Mr. Timmer's behalf, an amount of $850,000 in complete satisfaction
         of the amount owed by Mr. Timmer to Mr. Gallupe, which amount shall for
         all purposes hereunder be deemed to have been received by Mr. Timmer as
         part of the Purchase Price. The balance of the Purchase Price other
         than the Earn Out Amount, comprising $2,000,000, will be paid in the
         manner provided for in Section 2.04.

                  (ii) Simultaneously, each Individual Seller will sell to
         Purchaser those shares of Purchased Stock, those Purchased Options, and
         those Purchased Loan Accounts set forth opposite the name of each such
         Individual Seller on Schedule 2.03(b) of the Disclosure Schedule
         (representing, in the aggregate, 100% of each class of outstanding
         capital stock of each Target Company, all Options to acquire any
         capital stock or other securities of each Target Company, and all
         Liabilities of each Target Company to the Sellers and their
         Affiliates), in each case free and clear of all Liens, and the Selling
         Companies will sell the Purchased Assets to Purchaser free and clear of
         all Liens other than Permitted Liens, by delivering to Purchaser (i)
         stock certificates or stock indemnities evidencing all of the Purchased
         Stock duly endorsed by the Individual Sellers in blank or accompanied
         by stock powers duly executed by the Individual Sellers (and also, in
         the case of any married (by Law, common law or otherwise) Individual
         Seller resident in a community of property state, executed by the
         spouse of such Individual Seller) in blank, with all required stock
         transfer tax stamps affixed or provided for, (ii) assignments of all of
         the Purchased Options in the form of Exhibit B, duly executed by the
         Individual Sellers, reflecting the Purchaser as the assignee, (iii)
         assignments of all of the Purchased Loan Accounts in the form of
         Exhibit A, duly executed by every Seller on its own behalf and on
         behalf of every Affiliate of every such Seller, and (iv) a bill of sale
         and assignment in the form of Exhibit I hereto duly executed by each
         Selling Company.

                  (iii) The Purchaser shall deliver to the Selling Companies an
         instrument of assumption of liabilities in the form of Exhibit J-1
         hereto with respect to ASI and Exhibit J-2 hereto with respect to DTI,
         and shall deliver the Escrow Amount to the Escrow Agent and there shall
         also be delivered by Purchaser and Sellers the opinions, certificates
         and other agreements, documents and instruments to be delivered under
         Sections 6.01 and 6.02.

         2.04 ESCROW. On the Closing Date, the Purchaser, as collateral security
for the payment of the outstanding balance of the Purchase Price of Two Million
Dollars ($2,000,000) not paid to the Sellers at the Closing, shall execute and
deliver an Escrow Agreement in the form annexed hereto as Exhibit C (the "Escrow
Agreement") and Purchaser shall execute and deliver to and deposit with the
Escrow Agreements the sum of Two Million Dollars ($2,000,000) (the "Escrow
Amount"). The Escrow Amount shall be payable to the Sellers at the end of the
eighteenth month following the month in which the Closing occurs, pursuant to
the terms of the Escrow Agreement and subject to the right of the Purchaser and
Microdyne to indemnification hereunder pursuant to Article VIII hereof and the
provisions of the Escrow Agreement; 


                                       13
<PAGE>   19
provided, however, that with respect to any such payment to any Individual
Seller which would constitute actual or deemed compensation to such Individual
Seller in connection with such Individual Seller's employment with a Company or
with respect to which withholding is otherwise reflected in Section 2.03(b) of
the Disclosure Schedules, the Escrow Agent shall, in accordance with the terms
of the Escrow Agreement, withhold from such payment all withholding required in
connection therewith under applicable federal and state Tax or other relevant
Laws, and such withheld amount shall be deemed for all purposes hereunder to
have been paid to such Individual Seller. Sellers shall not be entitled at the
time of deposit thereof with the Escrow Agent to any of the Escrow Amount
deposited by the Purchaser with the Escrow Agent, and shall be entitled to such
of the Escrow Amount that becomes payable to Sellers only at such time when such
amounts become payable to Sellers pursuant to the terms of the Escrow Agreement.
Any amounts paid or released by the Escrow Agent to the Purchaser under Section
4(a) of the Escrow Agreement, including without limitation following an
arbitration and an arbitrators report or on the order of a court, shall be
treated in the manner contemplated by Section 8.02(f) hereof or, if such
treatment is not proper and permissible as contemplated by Section 8.02(f), as
though such amount had been paid to the Sellers on account of the Purchase Price
and then returned by the Sellers to the Purchaser under Article VIII hereof.

         2.05 EFFECT OF FAILURE OF ANY SELLER TO DELIVER. If any Individual
Seller shall fail to deliver on the Closing Date any shares of Purchased Stock
to be sold by him or her hereunder, such failure or refusal shall not relieve
any other Seller of his, her or its obligations hereunder, and Purchaser, at its
option and without prejudice to its rights against such defaulting Seller or
Sellers, shall have the right either to accept delivery of the remainder of the
shares of Purchased Stock and Purchased Assets that it is entitled to have
delivered to it hereunder with a reduction in the Purchase Price for such
undelivered securities, or to give notice of its refusal to accept delivery of
those shares of Purchased Stock and those Purchased Assets tendered, thereby
terminating all its obligations and liabilities to such tendering Sellers.

         2.06 EARN OUT AMOUNT.

         (a) The Purchaser shall, if the conditions in subsection (b) below are
met, pay the Earn Out Amount to the Sellers on September 1, 1999, by wire
transfer of immediately available funds to such account as each Seller may
reasonably direct by written notice delivered to the Purchaser by such Seller at
least three (3) Business Days before September 1, 1999, payable to each Seller
in the amount obtained by multiplying the Earn Out Amount by each Sellers'
Shareholder Percentage; provided, however, that with respect to any such payment
to any Individual Seller which would constitute actual or deemed compensation to
such Individual Seller in connection with such Individual Seller's employment
with a Company or with respect to which withholding is otherwise reflected in
Section 2.03(b) of the Disclosure Schedules, the Purchaser shall withhold from
such payment all withholding required in connection therewith under applicable
federal and state Tax or other relevant Laws, and such withheld amount shall be
deemed for all purposes hereunder to have been paid to such Individual Seller.

         (b) The Earn Out Amount shall be payable if the Acquired Businesses,
during the twelve (12) calendar month period commencing June 1, 1998 and ending
May 31, 1999, achieve an EBIT of $3,923,000 or more and revenues of $19,615,000
or more, both determined in accordance with GAAP as historically implemented by
the Target Companies, consistently applied, and both achieved by the operation
of the business in a manner not materially inconsistent with the Business Plans,
including with respect to research and development and capital and marketing
expenditure, except as otherwise provided for the next sentence.

                  (i) The EBIT shall be determined: (A) without any amortization
         of goodwill or write up of intangibles associated with the transactions
         contemplated hereby; (B) without any charge against the Acquired
         Businesses for any costs associated with the transactions contemplated
         by this 


                                       14
<PAGE>   20
         Agreement; (C) without any deduction or charge for any deemed
         compensation attributed to any Individual Seller arising in connection
         with the sale of the Purchased Stock or Purchased Options to the
         Purchaser under this Agreement; (D) without any charge against the
         Acquired Businesses for any general corporate or head office overhead
         charge by Microdyne; (E) with costs for employee benefits taken into
         account at whichever is the lower of the per employee (or, where a
         percentage of salary, at the same percentage) levels that existed prior
         to the Closing or the actual costs, provided however that if employee
         benefits are increased after the Closing with the approval of Mr.
         Timmer and such increase in benefits causes the costs per employee to
         exceed the pre-Closing costs per employee, then the costs per employee
         shall be taken into account at their actual amount; (F) after deduction
         of all incentive compensation, bonuses and commissions paid (not
         accrued) from June 1, 1998 through May 31, 1999 to employees and
         executives of the Acquired Businesses; and (G) with a charge against
         the Acquired Businesses for actual expenses incurred by Microdyne on
         behalf of the Acquired Businesses, including without limitation for
         insurance and other items purchased by Microdyne for its operating
         subsidiaries on a group wide basis.

                  (ii) The EBIT shall be determined after excluding the effect
         on the Acquired Businesses of any material changes to the Acquired
         Businesses caused or made by the Purchaser to which the Principal
         Stockholders then employed by the Acquired Businesses took exception or
         objected to at the time thereof. If the Purchaser makes or causes any
         material change to the Acquired Business to which the Principal
         Stockholders then employed by the Acquired Businesses take exception or
         object at the time thereof, and if it is reasonably likely that the
         Earn Out Amount would have been earned but for such change, then the
         Purchaser shall be obligated to pay the Earn Out Amount. Nothing herein
         shall be construed as in any way constraining the right of the
         Purchaser to make changes to the Acquired Businesses, subject to the
         Purchaser's obligation to pay the Earn Out Amount if so required under
         this paragraph (ii).

                  (iii) Any revenues, earnings and expenses derived from or
         related to (A) the exploitation by the Purchaser in its other
         facilities of any of the products or technology of the Acquired
         Businesses in markets or applications not being exploited by the
         Acquired Businesses on the Closing Date shall be excluded from the
         revenues and EBIT hereunder, and (B) any products or product lines that
         are transferred to the Acquired Businesses from Microdyne or its
         Affiliates or that are acquired for the Acquired Businesses by
         Microdyne.

                  (iv) The EBIT, revenue and balance sheet determinations will
         be determined in accordance with GAAP (except as otherwise set forth in
         this Section 2.06(b)) subject to all reserves with respect thereto, and
         may be adjusted retrospectively at any time up to the date on which the
         Earn-Out Amount is to be paid to reflect any matter or circumstance
         relevant to the determination thereof for the relevant period,
         including without limitation any receivables generated during such
         period which are unpaid at the end of such period and with respect to
         which a reserve is required to be made prior to the date on which the
         Earn-Out Amount is to be paid.

                  (v) If any one of the EBIT or revenue criteria are not met or
         achieved, then no Earn Out Amount shall be payable.

         (c) During the month of June, 1999, the Purchaser and those Principal
Stockholders who are employed by the Purchaser or the Target Companies at that
time shall prepare a balance sheet, statement of operations and cash flow for
the Acquired Businesses at and for the twelve (12) month period ending May 31,

ARTICLE III:        REPRESENTATIONS AND WARRANTIES OF SELLERS

         As an inducement to Purchaser to enter into this Agreement and to
consummate the transactions contemplated herein, and except as set forth in the
Disclosure Schedule (with Section references corresponding to those set forth
below), each of the Sellers hereby represents, warrants, covenants and agrees,
jointly and severally (subject to Article VIII), to and with Purchaser as
follows:

         3.01 ORGANIZATION AND QUALIFICATION. Each Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Maryland, in the case of Apcom, DTI and ASI, or California in the case of
Celerity, and has full corporate power and authority to conduct its business as
and to the extent now conducted and to own, use and lease its Assets and
Properties. Each Company is duly qualified, licensed or admitted to do business
and is in good standing in the jurisdictions listed in Section 3.01 of the
Disclosure Schedule, which are the only jurisdictions in which the ownership,
use or leasing of its Assets and Properties, or the conduct or nature of its
business, makes such qualification, licensing or admission necessary, except
where the failure to be so qualified, licensed or admitted would not have a
material adverse effect on such Company. The business now being conducted by
each Company has not been conducted under any other name.

         3.02 CAPITAL STOCK.

                  (a) The authorized capital stock of:

                           (i) Apcom consists of twenty million (20,000,000) 
         shares of shares of common stock, par value $0.01 per share; and

                           (ii) Celerity consists of five million (5,000,000)
         shares of common stock without par value.

                  (b) The only issued and outstanding shares of common stock of
the Target Companies are the shares of Purchased Stock, all of which are validly
issued, fully paid and nonassessable, and the issuance of all of which was in
compliance with all applicable Laws. The only Options to acquire shares of stock
in the Target Companies are the Purchased Options, all of the material terms of
which are set forth in Section 3.02(b) of the Disclosure Schedule. The share
ledger of each Target Company accurately reflects all issuances and transfers of
such Target Company's capital stock since the incorporation of such Target
Company.

                  (c) Except for the Purchased Stock and for shares of common
stock of the Target Companies issuable upon exercise of the Purchased Options,
no shares of the capital stock of the Target Companies have been issued or
reserved for issuance. Except for the Purchased Options, there are no
outstanding Options with respect to the capital stock of the Target Companies,
or agreements, arrangements or understandings to issue Options with respect to
the capital stock of the Target Companies and there are 


                                       16

preemptive rights with respect to the issuance or sale of the Target Companies'
capital stock.

owners of the Purchased Stock, the Purchased Options and the Purchased Loan
Accounts as set forth in Section 2.03(b) of the Disclosure Schedule free and
clear of all Liens. The delivery to the Purchaser at the Closing of the

form reflecting the Purchaser as the transferee and an assignment of the
Purchased Options reflecting the Purchaser as the assignee, executed in each
case by the Individual Seller identified in Section 2.03(b) of the Disclosure
Schedule as the owner thereof, will transfer to Purchaser good and valid title
to the Purchased Stock, the Purchased Options and the Purchased Loan Accounts,
free and clear of all Liens.

Companies of the transactions contemplated hereby and thereby have been duly and

Returns, if any, of the Companies that have been audited by the IRS or any other
Taxing Authority, and indicates those Tax Returns of the Companies that are
currently the subject of audit. No deficiencies, adjustments or changes in
assessments for any Taxes have been proposed, asserted or assessed against any
Company, and no Company expects any Taxing Authority to assess additional Taxes
against or in respect of it for any past period. Except as disclosed in Section
3.1 1 of the Disclosure Schedule, (i) there are no investigations, examinations,
reassessments, claims, actions, suits or proceedings pending or to the Seller's

raised or to the Seller's Knowledge threatened by any Taxing Authority. There

claims the payment of which is not yet due) for Taxes upon the Assets and
Properties of any Company. Sellers have delivered to Purchaser complete and
correct copies of all Tax Returns filed by any Company and all Tax examination
reports since January 1, 1996. No issue has been raised since that date by the
IRS or any other Taxing Authority in any audit of any Company which, by
application of similar principles, could be expected to result in a material
proposed deficiency for any period prior to Closing not yet audited or under
audit.

         (f) No Company has waived any statute of limitations in respect of
Taxes or agreed to any extension of time with respect to any Tax assessment or
deficiency.

         (g) No Company has received any written ruling related to Taxes or
entered into any written and legally binding agreement with the IRS or any other
Taxing Authority relating to Taxes.

         (h) No Company has any Liability for Taxes of any Person other than
such Company (i) as a transferee or successor, (ii) by reason of Section
1.1502-6 of the United States Treasury Regulations or any similar provision of
any other Law, (iii) by contract, or (iv) otherwise.

         (i) Except as set forth in Section 3.11 of the Disclosure Schedule, no
Company has been a member of a consolidated, combined, affiliated or unitary
group and no Company has filed or consented to the filing of any consolidated,
combined, affiliated or unitary or similar return with any entity with respect
to any Tax. No Company is a party to or is bound by any obligations under any
Tax sharing, Tax indemnity or similar agreement or arrangement.

         (j) No Company is a party to any joint venture, partnership or other

         Properties or this Agreement and the transactions contemplated hereby;

                  (ii) there are no facts or circumstances known to any Company
         or any Individual Seller that could reasonably be expected to give rise
         to any Action or Proceeding that would be required to be disclosed
         pursuant to clause (a) (i) above; and

                  (iii) neither any Company nor any Individual Seller has
         received notice, or is aware, of any Orders outstanding against any
         Company or any Individual Seller (relating to any Company or this
         Agreement).

         (b) Prior to the execution of this Agreement, the Companies have
delivered all responses of counsel for any Company to auditors' requests for
information regarding Actions or Proceedings pending or threatened against,
relating to or affecting any Company for the periods covered by the Audited
Financial Statements. Section 3.12(b) of the Disclosure Schedule sets forth all
Actions or Proceedings relating to or affecting any Company, any Individual
Seller (in his, her or its capacity as a stockholder of the Company) or any of
their respective Assets and Properties since January 1, 1995.

         3.13 COMPLIANCE WITH LAWS AND ORDERS. No Company is, nor has any
Company been at any time, in any material violation of or in any material
default under any Law or Order applicable to any Company or any of its
respective Assets and Properties. In furtherance and not limitation of the

with the offer, sale or purchase of any securities.

         3.14 PLANS.

         (a) Set forth in Section 3.14(a) of the Disclosure Schedule is a
complete and correct list of all Plans maintained or contributed to by any
Company, Plans pursuant to which any Company may have any Liability, and Plans
covering employees or former or retired employees of any Company ("Employees")
with respect to their employment with any Company. Except as disclosed in
Section 3.14(a) of the Disclosure Schedule, each Plan is in writing or has been
properly summarized in writing and true and complete copies of the following
items relating to each Plan, where applicable, have heretofore been delivered to
Purchaser: (i) the Plan and any trust, custodial or other funding agreement,
including all amendments thereto; (ii) the three most recent actuarial reports
and annual reports filed with any Governmental or Regulatory Authority 


                                       24
<PAGE>   30
for the three most recent Plan years; (iii) the most recent summary plan
description, all summaries of material modifications to such summary plan
descriptions and all material Employee communications relating to such Plans
distributed within the last twelve (12) months, and (iv) the most recent
custodian or trustee reports or other financial statement for funded Plans.

         (b) Each of the Plans that is a retirement, savings or other pension
plan as defined in Section 3(2) of ERISA has been determined by the IRS to be
tax-qualified under Section 401 of the Internal Revenue Code, and, each Company
has complied, in all material respects, with all applicable Laws in
administering such Plans, including specifically the provisions of ERISA. To the
Seller's Knowledge, no non-exempt prohibited transaction, as defined in Section
4975 of the Internal Revenue Code, has occurred with respect to any such Plans,
and no such Plan has incurred any accumulated funding deficiency, as defined in
Section 412 of the Internal Revenue Code, whether or not waived. There has not
been, with regard to any such Plan, any reportable event, as defined in Section
4043(b) of ERISA, that is required to be reported to the PBGC by any Law. The
fair market value of the assets of each such Plan that is subject to Title IV of
ERISA equals or exceeds the present value of all benefits accrued under such
Plan, whether or not vested, based on the actuarial assumptions that would be
used by the PBGC if the Plan were terminated as of the date of this Agreement or
as of the Closing Date. As to each of the Plans that is a health, severance,
insurance, disability and other employee welfare Plan, and all other employee
benefit plans and programs as defined in Section 3(1) of ERISA, except as set
forth in Section 3.14(b) of the Disclosure Schedule, the Company has complied,
in all material respects, with all applicable Laws in the administration thereof
including, without limitation, the provisions of ERISA when applicable. The
Company has not terminated any Plan or incurred any material liability to the
PBGC under Title IV of ERISA and, to the Seller's Knowledge, no condition exists
that could reasonably be expected to cause the Purchaser to incur any such
liability. All premiums payable to the PBGC have been paid when due. No
compensation or benefit that is or will be payable as a result of the
transactions contemplated by this Agreement will be characterized as an "excess
parachute payment" within the meaning of Section 280G of the Internal Revenue
Code.

         (c) All required employer contributions, premium payments and
source-deducted Employee contributions under the Plans have been made or will be
timely made and remitted to the funding agents thereunder. All such
contributions to the Plans for any period ending before the Closing Date that
are not yet, but will be, required to be made are properly accrued and reflected
on the Effective Date Balance Sheet or are disclosed in Section 3.14 (c) of the
Disclosure Schedule. No oral or written promise, commitment or representation
has been made by any Individual Seller or any Company (i) to amend any of the
Plans or to provide increased benefits thereunder to any of the Companies
present or former employees, independent contractors, directors, officers or
shareholders, except pursuant to the requirements, if any, of the Plans or any
collective bargaining agreements, (ii) to establish any new Plans, or (iii) to
fund or continue any Plan beyond the Closing Date. Except as set forth in
Section 3.14 (c) of the Disclosure Schedule, each Plan can be terminated on the
Closing Date without making any additional contribution to such Plan other than
normal contributions with respect to the current plan year.

         (d) Except as set forth in Section 3.14(d) of the Disclosure Schedule,
each Plan has been maintained, operated and administered in compliance with its
terms and all related documents or agreements and in compliance with all
applicable Laws. Except as set forth in Section 3.14(d) of the Disclosure
Schedule, any non-compliance or failure to properly administer a Plan or related
trust or fund has not exposed such Plan or related trust or fund or any Company,
nor could it result in any exposure of the Purchaser, to any Taxes, penalties or
Liabilities to any Person, or expose the Plan to disqualification or the trust
or fund to loss of tax exempt status.


                                       25
<PAGE>   31
         (e) There is no pending or, to the Seller's Knowledge threatened claim
(other than claims for benefits in the ordinary course), assessment, complaint,
proceeding or investigation of any kind before any Governmental or Regulatory
Authority with respect to any Plan.

         (f) All insurance premiums required with respect to any Plan up to the
Closing Date have been or shall be paid on or prior to the Closing Date, and,
with respect to any such insurance policy, there shall be no Liability of any
Company or the Purchaser in the nature of a retroactive rate adjustment, loss
sharing arrangement or other actual or contingent Liability arising wholly or
partially out of events occurring prior to the Closing Date.

         (g) All benefits, expenses and other amounts due and payable to or
under any Plan, and all contributions, transfers or payments required to be made
to any Plan, have been paid when due.

         (h) No Plan provides benefits, including without limitation death or
medical benefits, beyond termination of service or retirement other than (i)
coverage mandated by Law, (ii) deferred compensation benefits reflected on the
books of a Company and described in Section 3.14(h) of the Disclosure Schedule
or (iii) a pension plan as defined in Section 3(2) of ERISA.

         (i) Neither any Company nor any Plan has agreed to guarantee or
indemnify the performance of any Person with respect to any Plan.

         (j) As a result of the purchase of the Purchased Stock and the
Purchased Assets by the Purchaser, neither any Company nor the Purchaser shall
be obligated to make a payment to any individual with respect to severance or
compensation for personal services (other than salary and benefits at current
rates for services performed), nor shall any benefit under any Plan be
accelerated or become vested, including any stock options or similar rights to
stock.

owes brokerage, commissions or finders fees with respect to any such Real
Property Lease or Leased Real Property, except to the extent that a Company may
renew the term of any such Real Property Lease, in which case, any such
commissions and fees would be in amounts that are reasonable and customary for
premises similar to those leased, given their intended use and terms. No Company
has assigned, sublet, transferred, hypothecated or

force and effect and which, in the case of lease agreements in favor of the
Selling Companies, will be validly and enforceably assigned to the Purchaser as

The consummation of the transactions contemplated by this Agreement will neither

suspension of the Intellectual Property License Agreements, and each Company is
in compliance with, and has not breached (or would breach after notice or lapse
of time) any term of, the Intellectual Property License Agreements and, to the
Seller's Knowledge, all of the other parties to such Intellectual Property
License Agreements are in compliance with, and have not breached, any of the

                                       27
<PAGE>   33

Knowledge exist or prevail at the time of the preparation of the plan; provided,
however, that no representation or warranty is made or given that the Companies

of any Company.

                                       35
<PAGE>   41
any untrue statement of a material fact or omits to state a material fact
necessary in order to make the statements herein or therein, in the light of the
circumstances under which they were made, not misleading. The Principal
Stockholders and those other Individual Sellers who are directors or officers of
any of the Companies shall for the purpose of the preceding sentence only be
deemed to have knowledge or belief of any fact, matter or circumstance, or act

reckless disregard with respect thereto.

Companies or the Target Companies. Furthermore, the Purchaser and its
Representatives may disclose such information to the extent that they are
required to do so to comply with an Order, but upon receiving notice that any

ARTICLE VIII: INDEMNIFICATION

         8.01 INDEMNIFICATION.

         (a) From and after the Closing Date and subject to the limitation on

Purchaser, Microdyne and their respective stockholders and the general partners,
limited partners, officers, directors, employees, agents and Affiliates of each
of them (in each case, other than the Sellers) (collectively, the "Purchaser
Indemnities"), in respect of, and hold each of them harmless from and against,
and shall pay the full amount of, any and all Losses suffered, incurred or
sustained by any of them or to which any of them becomes subject, resulting
from, arising out of or relating to any misrepresentation or breach of warranty
or nonfulfillment of or failure to perform any covenant or agreement on the part

A to the Escrow Agreement) were such amount to have been paid to the Sellers
absent such Losses; (ii) subject to the


                                       50
<PAGE>   56
limitation on indemnity provided in Section 8.01(c) below and to (iii) below,
with respect to any Losses that exceed the Escrow Amount and the Earn-Out Amount
(if earned), the indemnification obligations of the Principal Stockholders and

each of the Other Stockholders shall not be liable therefor; and (iii) the
maximum amount of the indemnification obligations of each Principal Stockholder
shall be limited to the portion of the Purchase Price received by, or receivable

the entire Escrow Amount shall, notwithstanding the provisions of Section
8.02(f), be deemed to be part of the Purchase Price, and, as set forth in the
proviso to Section 2.01(a)(i), any amount of the Purchase Price withheld from a
Principal Stockholder under applicable Tax or other Laws shall be deemed to have
been paid to such Principal Stockholder.

         (b) From and after the Closing Date and subject to the limitation on
indemnity provided in Section 8.01(d), Purchaser shall indemnify the Individual
Sellers and their respective heirs, executors, personal representatives,
successors and assigns, and the Selling Companies and their respective
stockholders, officers, directors, employees, agents and Affiliates (the "Seller
Indemnities"') in respect of, and hold each of them harmless from and against,
and shall pay the full amount of, any and all Losses suffered, incurred or
sustained by any of them or to which any of them becomes subject, resulting

         (c) No amounts of indemnity shall be payable as a result of a claim
under Section 8.01(a) in respect of a misrepresentation or breach of warranty
(other than a claim based upon fraud or willful or criminal misconduct or any
claim pursuant to Sections 3.01 (first sentence) or 3.02 in which case the
following clauses (i) and (ii) shall not apply) (i) unless and until the
Purchaser Indemnities have suffered, incurred, sustained or become subject to
Losses with respect thereto in excess of $170,000 in the aggregate, in which
case the Purchaser Indemnities shall be entitled to seek indemnity for the
entire amount of such Losses, or (ii) to the extent that the Purchaser
Indemnities have suffered, incurred, sustained or become subject to Losses by
reason of all such claims in excess of the Purchase Price (for which purpose the
entire Escrow Amount shall, notwithstanding the provisions of Section 8.02(f),
be deemed to be part of the Purchase Price).

         (d) No amounts of indemnity shall be payable as a result of a claim
under Section 8.01(b) in respect of a misrepresentation or breach of warranty
(other than a claim based upon fraud or willful or criminal misconduct or
pursuant to Section 4.01, in which case the following clauses (i) and (ii) shall
not apply) (i) unless and until the Seller Indemnities have suffered, incurred,
sustained or become subject to Losses with respect thereto in excess of $170,000
in the aggregate, in which case the Seller Indemnities shall be entitled to seek
indemnity for the entire amount of such Losses, or (ii) to the extent that the
Seller Indemnities have suffered, incurred, sustained or become subject to
Losses by reason of all such claims in excess of $2,000,000.

         8.02 METHOD OF ASSERTING CLAIMS. All claims for indemnification by any
Indemnified Party under Section 8.01 will be asserted and resolved as follows:

         (a) In order for an Indemnified Party to be entitled to any
indemnification provided for under Section 8.01 in respect of, arising out of or
involving a claim or demand made by any Person not a party to this Agreement
against the Indemnified Party (a "Third Party Claim"), the Indemnified Party
must deliver


                                       51
<PAGE>   57
a Claim Notice to the Indemnifying Party within thirty (30) Business Days after
receipt by such Indemnified Party of written notice of the Third Party Claim;
provided, however, that failure to give such Claim Notice shall not affect the
indemnification provided hereunder except to the extent the Indemnifying Party
shall have been actually prejudiced as a result of such failure.

         (b) If a Third Party Claim is made against an Indemnified Party, the
Indemnifying Party shall be entitled to participate in the defense thereof and,
if it so chooses, to assume the defense thereof with counsel selected by the
Indemnifying Party, which counsel must be reasonably satisfactory to the
Indemnified Party, provided that all Indemnifying Parties with respect to such
Third Party Claim jointly acknowledge to the Indemnified Party its right to
indemnity pursuant hereto in respect of the entirety of such claim (as such
claim may be modified through written agreement of the parties or arbitration
hereunder) and provide assurances reasonably satisfactory to the Indemnified
Party that the Indemnifying Parties will be financially able to satisfy such
claim in full if it is decided adversely. Should the Indemnifying Party so elect
to assume the defense of a Third Party Claim, the Indemnifying Party shall not
be liable to the Indemnified Party for legal expenses subsequently incurred by
the Indemnified Party in connection with the defense thereof (except as
hereinafter provided), but shall continue to pay for any expenses of
investigation or any Loss suffered. If the Indemnifying Party assumes such
defense, the Indemnified Party shall have the right to participate in the
defense thereof and to employ counsel, at its own expense (except as hereinafter
provided), separate from the counsel employed by the Indemnifying Party.
Notwithstanding the foregoing, if (i) the Indemnifying Party shall not assume
the defense of a Third Party Claim with counsel satisfactory to the Indemnified
Party within five (5) Business Days of any Claim Notice, or (ii) legal counsel
for the Indemnified Party notifies the Indemnifying Party that there are or may
be legal defenses available to the Indemnified Party or to other Indemnified
Parties which are different from or additional to those available to the
Indemnifying Party, which, if the Indemnified Party and the Indemnifying Party
were to be represented by the same counsel, would constitute a conflict of
interest for such counsel or prejudice prosecution of the defenses available to
such Indemnified Party, or (iii) the Indemnifying Party shall assume the defense
of a Third Party Claim and fail to diligently and vigorously prosecute such
defense in a timely manner, then in each such case the Indemnified Party, by
notice to the Indemnifying Party, may employ its own counsel and control the
defense of the Third Party Claim and the Indemnifying Party shall be liable for
the reasonable fees, charges and disbursements of counsel employed by the
Indemnified Party; and the Indemnified Party shall be promptly reimbursed for
any such fees, charges and disbursements, as and when incurred. Whether the
Indemnifying Party or the Indemnified Party controls the defense of any Third
Party Claim, the parties hereto shall cooperate in the defense thereof. Such
cooperation shall include the retention and provision to the counsel of the
controlling party of records and information which are reasonably relevant to
such Third Party Claim, and making employees available on a mutually convenient
basis to provide additional information and explanation of any material provided
hereunder. The Indemnifying Party shall have the right to settle, compromise or
discharge a Third Party Claim (other than any such Third Party Claim in which
criminal conduct is alleged) without the Indemnified Party's consent if such
settlement, compromise or discharge (i) constitutes a complete and unconditional
discharge and release of all Indemnified Parties, and (ii) provides for no
relief other than the payment of monetary damages and such monetary damages are
paid in full by the Indemnifying Party, and in all other cases may not so settle
without the prior written consent of the Indemnified Party.

         (c) In the event any Indemnified Party should have a claim under
Section 8.01 against any Indemnifying Party that does not involve a Third Party
Claim, the Indemnified Party shall deliver an Indemnity Notice with reasonable
promptness to the Indemnifying Party. The failure by any Indemnified Party to
give the Indemnity Notice shall not impair such party's rights hereunder except
to the extent that an Indemnifying Party demonstrates that it has been actually
prejudiced thereby. If the Indemnifying Party notifies the Indemnified Party
that it does not dispute the claim described in such Indemnity Notice or fails


                                       52
<PAGE>   58
to notify the Indemnified Party within the Dispute Period as to whether the
Indemnifying Party disputes the claim described in such Indemnity Notice, the
Loss in the amount specified in the Indemnity Notice will be conclusively deemed
a Liability of the Indemnifying Party under Section 8.01 and the Indemnifying
Party shall pay the amount of such Loss to the Indemnified Party on demand. If
the Indemnifying Party has timely disputed its Liability with respect to such
claim, the Indemnifying Party and the Indemnified Party will proceed in good
faith to negotiate a resolution of such dispute, and if not resolved through
negotiations within the Resolution Period, such dispute shall be resolved by
arbitration as provided in Article 11.

         (d) The indemnification provisions of this Article VIII shall
constitute the sole and exclusive remedy of the parties hereto, for any
inaccuracy, untruth, incompleteness or other breach of any representation or
warranty contained in or made pursuant to this Agreement or for any breach of or
failure to perform any covenant or agreement made in this Agreement or otherwise
arising out of the contemplated transactions, and the parties each waive any
other remedy, which they or any other Person entitled to indemnification
hereunder may have at law or in equity with respect thereto. The amount of
Losses suffered by any Person entitled to indemnification shall be reduced by an
amount equal to any insurance recovery received by such Person with respect to
such Loss and shall be reduced or increased by any Tax benefit or detriment
attributable to the realization of such Loss and any Tax benefit or detriment
attributable to the proper accounting of the Tax consequences of the receipt of
any indemnification payment payable hereunder.

         (e) Notwithstanding anything contained in this Agreement to the
contrary, at and after the Closing, no Seller shall be entitled to any
indemnification, right of contribution or other right of recovery from either
Target Company in connection with any claim made by or which could be made by an
Indemnified Party against a Target Company or which a Target Company could be
liable for, all of which are irrevocably waived and released by each Seller.

         (f) Any payment under this Article VIII shall be treated for tax
purposes as an adjustment of the Purchase Price to the extent such
characterization is proper and permissible under relevant Tax Laws, or,
alternatively, by Purchaser as an offset to a Tax benefit item, if such
characterization is proper under such Tax Laws.

Purchaser is not then in material breach of any material provision of this
Agreement and there has been any one or more material misrepresentations in or
breaches of the representations or warranties made by Sellers herein that, if

Purchaser grounds not to close under Section 6.02 when taken into account with
all other uncured misrepresentations in or breaches of such representations or
warranties as to which Purchaser shall have given notice to Sellers'
Representative as provided in this paragraph (b); a termination pursuant to this
paragraph (b) shall become effective (i) fifteen (15) days after such notice

<PAGE>   59
         (c) by Purchaser if Purchaser is not then in material breach of any
provision of this Agreement after written notice to Sellers' Representative of
the failure by Sellers to perform and satisfy in any material respect any of
their material obligations required to be performed and satisfied by Sellers on
or prior to the Closing Date, if the aggregate of all such failures shall be
material; a termination pursuant to this paragraph (c) shall become effective
(i) fifteen (15) days after such notice with respect to such a failure that is
not capable of being cured on or prior to the Closing Date, or (ii) immediately
prior to the Closing with respect to such a failure that is capable of being
cured, but is not cured, on or prior to the Closing Date;

         (d) by Sellers after written notice by Sellers' Representative to
Purchaser if Sellers are not then in material breach of any material provision
of this Agreement and there has been one or more material misrepresentations in
or material breaches of the representations or warranties made by Purchaser
herein which, if not cured on or prior to the Closing Date, could be reasonably
expected to give Sellers grounds not to close under Section 6.01 when taken into
account with all other uncured misrepresentations in or breaches of such
representations or warranties as to which Sellers' Representative shall have
given notice to Purchaser as provided in this paragraph (d); a termination
pursuant to this paragraph (d) shall become effective (i) fifteen (15) days
after such notice with respect to such a misrepresentation or breach that is not
capable of being cured on or prior to the Closing Date, or (ii) immediately
prior to the Closing Date with respect to such a misrepresentation or breach
that is capable of being cured, but is not cured, on or prior to the Closing
Date;

         (e) by Sellers if Sellers are not then in material breach of any
material provision of this Agreement after written notice by Sellers'
Representative to Purchaser of Purchaser's failure to perform and satisfy in any
material respect any of its material obligations under this Agreement required
to be performed and satisfied by Purchaser on or prior to the Closing Date, if
the aggregate of all such failures shall be material; a termination pursuant to
this paragraph (e) shall become effective (i) fifteen (15) days after such
notice with respect to such a failure that is not capable of being cured on or
prior to the Closing Date, or (ii) immediately prior to the Closing Date with
respect to such a failure that is capable of being cured, but is not cured, on
or prior to the Closing Date;

         (f) by Purchaser or by Sellers' Representative, if the Closing shall
not have been consummated by September 30, 1998; provided, however, that neither
Purchaser nor Sellers may terminate this Agreement pursuant to this paragraph
(f) if the Closing shall not have been consummated within such time period by
reason of the failure of such party or any of its Affiliates to perform in all
material respects any of its covenants or agreements contained in this
Agreement; and

         (g) by Purchaser or Sellers' Representative if any Law or Order shall
hereafter be enacted or become applicable that makes the transactions
contemplated hereby or the consummation of the Closing illegal or otherwise
prohibited, or if any Order enjoining any party hereto from consummating the
transactions contemplated hereby is entered and such Order shall become final
and nonappealable.

         The party desiring to terminate this Agreement pursuant to the
foregoing provisions shall give written notice of such termination to the other
party.

         9.02 EFFECT OF TERMINATION. If this Agreement is terminated as
permitted by Section 9.01, such termination shall be without liability of any
party to any other party to this Agreement except as hereinafter expressly
provided in this Section 9.02. If such termination shall result from the breach
by any party of its representations, warranties or covenants contained in this
Agreement, such party shall be fully liable for any and all Losses incurred or
suffered by the other parties as a result of such failure or breach and such
termination shall not be deemed to be an election of remedies. The provisions of
Sections 5.04, this Section


                                       54
<PAGE>   60
9.02 and Articles X, XI, and XII shall survive any termination of this Agreement
pursuant to this Article IX, and each party hereto shall be fully responsible
for any breach of Section 5.04, whether or not such breach occurs prior to the
termination of this Agreement.

ARTICLE X: SELLERS' REPRESENTATIVE

         10.01 APPOINTMENT OF SELLERS' REPRESENTATIVE. Mr. Gary Gallupe is
hereby appointed as agent and attorney-in-fact (the "Sellers' Representative")
for each Seller, to give and receive notices and communications; to authorize
delivery to Purchaser of payments from the Escrow Fund in satisfaction of claims
by Purchaser; to object to such deliveries; to agree to, negotiate, enter into
settlements and compromises of, and demand arbitration and comply with Orders
with respect to, any claims; to amend this Agreement (subject to Section 12.02)
or the Escrow Agreement; to take all other actions set forth in this Agreement
to be taken by the Sellers' Representative; and to take all actions necessary or
appropriate in the judgment of the Sellers' Representative for the
accomplishment of the foregoing. Such agency may be changed by the Sellers from
time to time upon not less than thirty (30) days prior written notice to
Purchaser and the Escrow Agent; provided that the Sellers' Representative may
not be removed unless Sellers holding Shareholder Percentages totaling more than
50% agree to such removal and select a substituted agent. No bond shall be
required of the Sellers' Representative, and the Sellers' Representative shall
not receive compensation for services as such. Notices or communications to or
from the Sellers' Representative shall constitute notice to or from each of the
Sellers or their permitted transferees.

         10.02 LIMITATION OF LIABILITY. The Sellers' Representative shall not be
liable for any act done or omitted hereunder as Sellers' Representative while
acting in good faith and in the exercise of reasonable judgment. The Sellers
shall severally indemnify the Sellers' Representative and hold him or her
harmless against any loss, liability or expense incurred without negligence or
bad faith on the part of the Sellers' Representative and arising out of or in
connection with the acceptance or administration of the Sellers'
Representative's duties hereunder, including the reasonable fees and expenses of
any legal counsel retained by the Sellers' Representative.

         10.03 ACTIONS BINDING. A decision, act, consent or instruction of the
Sellers' Representative shall constitute a decision of all the Sellers and shall
be final, binding and conclusive upon each of such Sellers, and the Escrow Agent
and Purchaser may rely upon any such decision, act, consent or instruction of
the Sellers' Representative as being the decision, act, consent or instruction
of each and every such Seller. The Escrow Agent and Purchaser are hereby
relieved from any Liability to any Person for any acts done by them in
accordance with such decision, act, consent or instruction of the Sellers'
Representative.

ARTICLE XI: ARBITRATION OF DISPUTES

         11.01 ARBITRATION. The parties agree that, except as provided in
Section 5.06(b) hereof arbitration shall be the exclusive and final means for
resolving any and every dispute, controversy, claim, or difference ("Disputes")
related to or arising out of or in connection with this Agreement, or any
commercial relationship or dealings of the parties that are related to or arise
out of or in connection with the subject matter of this Agreement (including
without limitation any questions concerning the scope and application of this
arbitration clause or the arbitrability of any Dispute under this clause), which
arbitration shall be conducted according to the rules then in effect of the
American Arbitration Association (the "AAA"), or such other rules as the AAA may
designate.

         11.02 PROCEDURE FOR ARBITRATION


                                       55
<PAGE>   61
         (a) The right of any party to require the arbitration of any Dispute
hereunder and the arbitration of any Dispute hereunder shall be governed by the
Federal laws of the United States (including expressly, but without limitation,
the Federal Arbitration Act).

         (b) The arbitration shall be held in Fairfax, Virginia and shall be
administered by the rules (the "Rules") then in effect of the AAA. Demand for
arbitration (an "Arbitration Notice") shall be delivered by the party demanding
arbitration under this Agreement (the "Initiating Party") to the party (or
parties) with whom arbitration is sought in accordance with the procedure set
forth in the Rules. The parties shall agree upon an arbitrator within thirty
(30) calendar days after the demand for arbitration is served. If they fail to
do so within such time, the arbitrator, or a panel of three arbitrators if so
requested by any party to the Dispute, shall be appointed by the AAA. If the
arbitrator dies, becomes disqualified or incapacitated, or fails or refuses to
act before the matter or matters subjected to such arbitration have been
determined, then, in place of such arbitrator, a new arbitrator shall promptly
be appointed in the same manner as such arbitrator. The arbitrator or
arbitration panel shall decide any matter before him or it in accordance with
this Agreement, including without limitation the law chosen by the parties in
Section 12.08 to govern this Agreement, which law shall also be the applicable
law to govern the arbitration proceedings. The arbitrator shall have the power
and the discretion to order discovery and the taking of depositions.

         (c) The arbitrator or arbitration panel shall proceed promptly and
diligently and render his or its decision as soon as practicable. The decision
of the arbitrator or arbitration panel shall be in writing and presented in
separate findings of fact and conclusions of law (the "Arbitrators' Report")
which shall be a final and binding award on the parties from which no appeal may
be taken, and an order confirming the award or judgment upon the award may be
entered in any court having jurisdiction thereto.

         (d) All fees, costs and expenses (including reasonable attorneys' fees
and expenses) incurred by a party that prevails on any issue in any arbitration
commenced hereunder or in any judicial proceeding seeking to enforce this
agreement to arbitrate disputes or seeking to enforce any order or award of any
arbitration hereunder shall be assessed against the party or parties that do not
prevail on such issue or issues.

         11.03 LIMITATION ON POWERS OR ARBITRATORS. Notwithstanding the
foregoing, it is hereby agreed that the arbitrator or arbitration panel shall
only have the power to order or grant relief in a manner that is directly
related to the subject matter of the dispute before the arbitrator or
arbitration panel, that the relief or order that may be granted by the
arbitrator or arbitration panel shall be limited to that which a court of
competent jurisdiction would have had the power to order or grant were the
dispute to have been heard before such court, and that no arbitrator or
arbitration panel shall have any power to add to, alter or modify the terms and
conditions of this Agreement or any other agreement executed and delivered in
connection herewith or to decide any issue which does not arise from the
interpretation or application of the provisions of this Agreement.

delivered personally to the address as provided in this Section, be deemed given
upon delivery, (ii) if delivered by facsimile transmission to the facsimile
number as provided for in this Section, be deemed given upon receipt, (iii) if
delivered by mail in the manner described above to the address as provided in
this Section, be deemed given on the earlier of the fourth Business Day
following mailing or upon receipt and (iv) if delivered by overnight courier to

communication is received by any other Person to whom a copy of such notice is
to be delivered pursuant to this Section). Any party from time to time may
change its address, facsimile number or other information for the purpose of
notices to that party by giving notice specifying such change to the other
parties hereto.

         12.02 ENTIRE AGREEMENT, AMENDMENT. This Agreement, the Exhibits hereto,
the Disclosure Schedule and the Operative Agreements supersede all prior
discussions and agreements between the parties with respect to the subject
matter hereof and thereof and contain the sole and entire agreement between the
parties hereto with respect to the subject matter hereof and thereof. This
Agreement may be amended, supplemented or modified only by a written instrument
duly executed by or on behalf of the Purchaser and the Sellers' Representative,
except that the consent of all Sellers shall be required to change the Purchase
Price. The terms and provisions of this Agreement are intended solely for the
benefit of each party hereto and their respective successors or permitted
assigns, and it is not the intention of the parties to confer third-party
beneficiary rights, and this Agreement does not confer any such rights, upon any
other Person other than any Person entitled to indemnity under Article VIII.

         12.03 EXPENSES. Except as otherwise expressly provided in this
Agreement (including without limitation as provided in Article VIII), each party
will pay its own costs and expenses incurred in connection with this Agreement,
the Operative Agreements, and the transactions contemplated hereby and thereby.

         12.04 CUMULATIVE REMEDIES. The rights, remedies, powers and privileges
herein provided are cumulative.

         12.05 WAIVER. Any term or condition of this Agreement may be waived at
any time by the party that is entitled to the benefit thereof, but no such
waiver shall be effective unless set forth in a written instrument duly executed
by or on behalf of the party waiving such term.

         12.06 NO ASSIGNMENT, BINDING EFFECT. Neither this Agreement nor any
right, interest or obligation hereunder may be assigned (by operation of law or
otherwise) by Sellers or by Purchaser without the prior written consent of
Purchaser or the Seller's Representative, respectively, and any attempt to do so
will be void. Subject to the preceding sentence, this Agreement is binding upon,
inures to the benefit of and is enforceable by the parties hereto and their
respective heirs, executors, personal representatives, successors and assigns.

         12.07 INVALID PROVISIONS. If any provision of this Agreement is held to
be illegal, invalid or unenforceable under any present or future Law, and if the
rights or obligations of any party hereto under this Agreement will not be
materially and adversely affected thereby, (a) such provision will be fully
severable,


                                       58
<PAGE>   64
(b) this Agreement will be construed and enforced as if such illegal, invalid or
unenforceable provision had never comprised a part hereof, (c) the remaining
provisions of this Agreement will remain in full force and effect and will not
be affected by the illegal, invalid or unenforceable provision or by its
severance here from and (d) in lieu of such illegal, invalid or unenforceable
provision, there will be added automatically as a part of this Agreement a
legal, valid and enforceable provision as similar in terms to such illegal,
invalid or unenforceable provision as may be possible.

         12.08 GOVERNING LAW. This Agreement shall be governed by and construed
in accordance with the domestic laws of the Commonwealth of Virginia without
giving effect to any choice of law or conflict of law provision or rule (whether
of the Commonwealth of Virginia or any other jurisdiction) that would cause the
application of the laws of any jurisdiction other than the Commonwealth of
Virginia.

         12.09 CONSTRUCTION.

                  (a) The parties hereto intend that each representation,
warranty, and covenant contained herein shall have independent significance. If
any party has breached any representation, warranty or covenant contained herein
in any respect, the fact that there exists another representation, warranty or
covenant relating to the same subject matter (regardless of the relative levels
of specificity) that the party has not breached shall not detract from or
mitigate the fact that the party is in breach of the first representation,
warranty or covenant.

                  (b) The parties hereto agree that this Agreement is the
product of negotiation between sophisticated parties and individuals, all of
whom were represented by counsel, and each of whom had an opportunity to
participate in and did participate in the drafting of each provision hereof.
Accordingly, ambiguities in this Agreement, if any, shall not be construed
strictly or in favor of or against any party hereto but rather shall be given a
fair and reasonable construction without regard to the rule of contra
proferentum.

         12.10 TIME PERIODS. When any provision of this Agreement provides for
the expiration of a time period or requires the giving of a notice on a day
which is other than a Business Day, such time period or day shall be extended to
the next succeeding Business Day.

         12.11 COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which will be deemed an original, but all of which
together will constitute one and the same instrument.

                            [Signature Page Follows]

conditions of this Agreement, to make Advances to the Borrower from time to
time on any Business Day during the period from the date hereof until the
Advance Termination Date, in an aggregate amount not to exceed at any time
outstanding the amount of such Bank's Advance Commitment.  Within the 





                                      -23-
<PAGE>   27

limits of the aggregate principal amount of the Advance Commitment, the Borrower
may borrow, prepay pursuant to Section 2.7 and reborrow the Advances; provided,
however, that no Advance will be disbursed by any Bank if, after such
disbursement, (1) a prepayment would be required under Section 2.7(d) or (2) the
aggregate amount of outstanding Advances and Letters of Credit would exceed the
Maximum Amount.

            (b)   The proceeds of the Advances shall be used (1) to refinance
existing loans made by Crestar Bank to the Borrower, (2) for short-term
working capital purposes, (3) for Capital Expenditures, (4) to pay such Debt
of the Targets of the Oasis Acquisition as shall be requested to be paid in

ordinary and customary corporate purposes, and no other purpose.

            (c)   The Borrower shall submit to the Agent a written request
for Advances in accordance with Section 4.6 hereof.  The Agent may also
accept telephonic or oral requests for Advances which are otherwise in
accordance with Section 4.6 hereof, and in so doing, may act upon such
request from anyone believed by the Agent to have the authority to make such
request.  Each Bank shall, before 1:00 p.m. (Bethesda, Md., time) on the date
of the borrowing of such Advances as specified in the Borrower's written
request therefor, make available for the account of its Applicable Lending
Office to the Agent at its address referred to in Section 12.2, in same day

Borrower may direct.

            (d)   The obligation of the Borrower to repay the Advances made

Credit for the account of the Borrower from time to time until the Advance
Termination Date; provided, however, that no Letter of Credit shall be issued
if, after such issuance, (1) a prepayment would be required under
Section 2.7(d), or (2) the aggregate amount of outstanding Advances and
Letters of Credit would exceed the Maximum Amount.  The form of each such
Letter of Credit shall be approved by the Agent.  The Advance Commitment of
each Bank shall be reduced by each Bank's Commitment Percentage of the
Letters of Credit. In no event shall (i) the aggregate amount of outstanding
Letters of Credit exceed $3,000,000 at any time; or (ii) the expiration of
any Letter of Credit extend beyond the earlier of the Advance Termination

<PAGE>   28

            (b)   Prior to the issuance of any Letter of Credit, the Agent
must receive an appropriately completed LC Agreement, executed by the
Borrower, not less than five Business Days prior to the date on which the
Letter of Credit is to be issued, and a written notice describing in
reasonable detail the proposed terms of such Letter of Credit and the nature
of the transactions or obligations to be supported thereby.  In the event of
a conflict between the terms of any LC Agreement and the terms of this
Agreement, this Agreement shall control.  The Borrower agrees to reimburse
the Agent on demand for any drawing paid by the Agent under a Letter of
Credit, together with interest thereon from the date of such demand at the
rate applicable to Base Rate Advances.

            (c)   (1)   As consideration for the issuance of any Letters of
Credit, the Borrower agrees to pay to the Agent, for the ratable benefit of
the Banks, a letter of credit fee equal to the Applicable LIBOR Margin per
annum on the daily aggregate face amount of all Letters of Credit outstanding
and undrawn.  The fee provided for in this Section 2.2()(1) shall be payable
quarterly in arrears on each Quarterly Payment Date, commencing with the
first such date to occur after the Closing Date on which any Letter of Credit
shall be outstanding, and on the Advance Termination Date.

                  (2)  As additional consideration for the issuance of any
Letters of Credit, in addition to the fee payable under Section 2.2()(1)
hereof, the Borrower agrees to pay to the Agent, for its own account, an
opening fee of $200 per Letter of Credit and a fronting fee, in addition to
the processing, administrative, and similar fees of the Agent in connection
with the Letters of Credit, equal to 0.10% per annum on the daily aggregate
face amount of all Letters of Credit outstanding and undrawn; provided,
however, that the minimum fronting fee shall be $500 per Letter of Credit
issued and outstanding.  The opening fee shall be paid on the date of
issuance of each Letter of Credit and the fronting fee provided for in this
Section 2.2()(2) shall be payable quarterly in arrears on each Quarterly
Payment Date, commencing with the first such date to occur after the Closing
Date on which any Letter of Credit shall be outstanding, and on the Advance
Termination Date.

            (d)   The Agent shall irrevocably grant to each Bank, and, to
induce the Agent to issue Letters of Credit hereunder, each Bank irrevocably
agrees to accept and purchase from the Agent, on the terms and conditions
hereinafter stated, for such Bank's own account and risk, an undivided
participation interest equal to such Bank's Advance Commitment Percentage in
the Agent's obligations and rights under each Letter of Credit issued
hereunder and any amounts paid by the Agent thereunder.  Each Bank
unconditionally and irrevocably agrees with the Agent that, if any amounts
are paid under any such Letter of Credit for which the Agent is not
reimbursed in full by the Borrower in accordance with the terms of this
Agreement, such Bank shall pay to the Agent, upon demand, at the Agent's
address for notices specified in Section 12.2 below, such Bank's Advance
Commitment Percentage of such amounts paid by the Agent that are not so
reimbursed.  Each Bank acknowledges and agrees that its obligation to make
such payment to the Agent is absolute and unconditional and shall not be
affected by any circumstance whatsoever, regardless of whether the conditions
precedent in Article 6 are then 





                                      -25-
<PAGE>   29

satisfied, the Advance Commitments are then in effect, a Default or an Event of
Default then exists or all of the Loans have been accelerated.

            (e)   If any amount required to be paid by any Bank to the Agent
pursuant to Section 2.2() in respect of any unreimbursed portion of any
payment made by the Agent under any Letter of Credit is not paid to the Agent
within three Business Days after the date such payment is due, such Bank
shall pay to the Agent, on demand, an amount equal to the product of (1) such
amount, times (2) the daily average Federal Funds Rate, as quoted by the
Agent, during the period from and including the date such payment is required
to the date on which such payment is immediately available to the Agent,
times (3) a fraction, the numerator of which is the number of days that
elapse during such period and the denominator of which is 360.  If any such
amount required to be paid by any Bank pursuant to Section 2.2()  is not in
fact made available to the Agent by such Bank within three Business Days
after the date such payment is due, the Agent shall be entitled to recover
from such Bank, on demand, such amount with interest thereon calculated from
such due date at the rate per annum then applicable to Base Rate Advances
hereunder.  Further, such Bank shall be deemed to have assigned any and all
payments made of principal and interest on its Loans, and any other amounts
due to it hereunder to the Agent to fund its participation in the Letter of
Credit Obligations that such Bank failed to purchase under this Section until
such amount has been purchased (as a result of assignment or otherwise).  A
certificate of the Agent submitted to any Bank with respect to any amounts
owing under this Section shall be conclusive in the absence of manifest error.

            (f)   Whenever, at any time after the Agent has made payment
under any Letter of Credit and has received from any Bank its pro rata share
of such payment in accordance with Section 2.2(), the Agent receives any
payment related to such Letter of Credit (whether directly from the Borrower
or otherwise, including proceeds of Collateral applied thereto by the Agent),
or any payment of interest on account thereof, the Agent will pay to such
Bank its pro rata share thereof; provided, however, that in the event that
any such payment received by the Agent shall be required to be returned by
the Agent, such Bank shall return to the Agent, for the account of the Agent,
the portion thereof previously distributed by the Agent to it.

            (g)   The Borrower's obligations under this Section 2.2 shall be
absolute and unconditional under any and all circumstances, irrespective of
any set-off, counterclaim or defense to payment that the Borrower may have or
have had against the Agent or any beneficiary of a Letter of Credit;
provided, however, that nothing in this Section 2.2(g) shall constitute a
waiver of any claim that the Borrower may have against the Agent in
connection with a Letter of Credit under applicable law, including a claim
for wrongful payment.  The Borrower also agrees with the Agent that the Agent
shall not be responsible for, and the Borrower's Letter of Credit Obligations
shall not be affected by, among other things, the validity or genuineness of
any documents or of any endorsements thereon, even though such documents
shall prove in fact to be invalid, fraudulent or forged, or any dispute
between or among the Borrower and any beneficiary of any Letter of Credit or
any other party to which such Letter of Credit may be transferred, or any
claims whatsoever of the Borrower against any beneficiary of such Letter of
Credit or any 





                                      -26-

negligence or willful misconduct. The Agent shall not be liable for any error,
omission, interruption or delay in transmission, dispatch or delivery of any
message or advice, however transmitted, in connection with any Letter of Credit,

under or in connection with any Letter of Credit or the related drafts or
documents, if done in the absence of gross negligence or willful misconduct and
in accordance with the standards of care specified in the Uniform Customs and
Practice for Documentary Credits (1994 Revision), International Chamber of
Commerce Publication No. 500, and, to the extent not inconsistent therewith, the
UCC, shall be binding on the Borrower and shall not result in any liability of
the Agent to the Borrower.

            (h)   The issuance by the Agent of any modification, renewal or
supplement to any Letter of Credit hereunder shall be subject to the same
conditions under this Section 2.2 to the issuance of new Letters of Credit,
and no such modification, renewal or supplement shall be issued hereunder
unless either (1) the respective Letter of Credit would have complied with
such conditions had it originally been issued hereunder in such modified or
supplemented form or (2) each Bank shall have consented thereto.

closing thereof, which shall be on the Closing Date.  Each of the Acquisition
Company and any Target which, upon consummation of the Oasis Acquisition,
becomes a Subsidiary of the Borrower, shall become a Loan Party pursuant to
the provisions of Section 9.1.

     SECTION 2.5. Interest.  The Borrower shall pay interest on the
unpaid principal amount of each Loan from the date of such Loan until such
principal amount shall be paid in full, on each Interest Payment Date, and on
the Advance Termination Date and the maturity date of the Oasis Acquisition
Loan, as applicable, at the following rates per annum:

            (a)   Base Rate Loans.  During such periods as such Loan is a
Base Rate Loan, a rate per annum equal at all times to the Base Rate plus the
Applicable Base Rate Margin in effect from time to time.

            (b)   Other Loans.  During such periods as such Loan is a LIBOR
Loan or a Floating LIBOR Loan, at a rate per annum equal to, as applicable,
the Floating LIBOR Rate or the Adjusted  LIBOR for the applicable Interest
Period, plus the Applicable LIBOR Margin in effect from time to time.

     SECTION 2.6. Designation, Conversion or Continuation of LIBOR
Loans.  The Borrower shall have the right (a) to designate any portion of an
Advance or the Oasis Acquisition Loan to be a LIBOR Loan, (b) to Continue any
LIBOR Loan or portion thereof into a subsequent Interest Period, and (c) to
Convert any Base Rate Loan or Floating LIBOR Loan into a LIBOR Loan, subject
in each case to the selection of Interest Periods in accordance with the
definition thereof, and the provisions set forth below.  Each such
designation, Conversion or Continuation shall be made upon prior irrevocable
written or telephonic notice to the Agent.  Each designation, Continuation
and Conversion shall be subject to the following:




                                      -28-
<PAGE>   32

                  (1)   in the case of a designation, Continuation or
Conversion of less than all Advances and the Oasis Acquisition Loan, the
aggregate principal amount of Loans designated, Continued or Converted shall
not be less than $500,000 or an integral multiple of $100,000 above $500,000;

                  (2)   if a Loan is being Continued as a LIBOR Loan, the
first Interest Period with respect thereto shall commence on the date of such
Continuation;

                  (3)   if a Loan or a portion thereof is being designated as
or Converted to a LIBOR Loan, the first Interest Period with respect thereto
shall commence on the second Business Day following the Agent's receipt of
the notice required above;

                  (4)   a LIBOR Loan may be Converted to a Base Rate Loan or
Floating LIBOR Loan only on the last day of an Interest Period;

                  (5)   each request for a LIBOR Loan or a Continuation
thereof which shall fail to state an applicable Interest Period, shall be
deemed to be a request for an Interest Period of a one month duration; and

                  (6)   subject to Section 4.6, a Base Rate Loan may be
Converted to a Floating LIBOR Loan, and vice versa, at any time.

In the event that the Borrower shall not give the required notice to
designate a Loan as a LIBOR Loan, continue a Loan as a LIBOR Loan into a
subsequent Interest Period, or Convert any Loan into a LIBOR Loan, such Loan
(unless repaid) shall be made as a Floating LIBOR Loan or shall automatically
be or become a Floating LIBOR Loan at the expiration of the then-current
Interest Period, as applicable.

     SECTION 2.7. Prepayments.

            (a)   Subject to Section 4.5, the Borrower shall have the right
at any time and from time to time to prepay any Base Rate Loan or Floating
LIBOR Loan, in whole or in part, without premium or penalty.

            (b)   Subject to Section 4.5, the Borrower shall have the right
to prepay any LIBOR Loan, in whole or in part, on the last day of the
then-current Interest Period in effect for such LIBOR Loan.  The Borrower
shall not prepay any LIBOR Loan except at the end of the Interest Period in
effect for such Loan.

            (c)   Partial prepayments of the Oasis Acquisition Loan shall be
applied to installments due thereunder in the inverse order of their
maturities.  Prepayments of the Oasis Acquisition Loan may not be reborrowed



                                      -29-
<PAGE>   33

            (d)   The Borrower immediately shall, first prepay the Advances
and, second, provide cover for the Letters of Credit as specified below, to
the extent that the Borrowing Base is less than 100% of Borrowing Base Credit
Extensions.  In the event the Borrower shall be required to provide cover for
the Letters of Credit, the Borrower shall effect the same by paying to the
Agent immediately available funds in an amount equal to the required amount,
which funds shall be retained by the Agent in a cash collateral account (as
collateral security in the first instance for the Letter of Credit
Obligations) until such time as the Letters of Credit shall have been
terminated and all of such Letter of Credit Obligations are paid in full.

     SECTION 2.8. Reduction of Commitments.

            (a)   The Oasis Acquisition Loan Commitment shall be
automatically reduced on the date of the disbursement of the Oasis
Acquisition Loan to Zero Dollars ($0.00).

            (b)   The Borrower shall have the right at any time and from time
to time (1) so long as no Loans, Letters of Credit or Obligations are
outstanding, to terminate the Advance Commitments, and (2) to reduce the
aggregate unused amount of the Advance Commitments (for which purpose use of
the Advance Commitment shall be deemed to include the aggregate amount of
outstanding Letters of Credit); provided that (i) the Borrower shall give
notice of each such termination or reduction as provided in Section 4.5
hereof, and (ii) each partial reduction shall be in an aggregate amount equal
to at least $1,000,000 (or a larger integral multiple of $500,000).

            (c)   Any Advance Commitment once terminated or reduced may not
be reinstated.

                             YIELD PROTECTION, ETC.

     SECTION 3.1. Suspension of LIBOR Loans.

            (a)   If the Agent is unable to determine LIBOR for any LIBOR
Loan for any reason, (1) the Agent shall forthwith notify the Borrower and
the Banks of such determination, (2) any request for LIBOR Loans shall be
withdrawn or changed to a request for Base Rate Loans, at the discretion of
the Borrower, (3) each LIBOR Loan will automatically, on the last day of the
then-existing Interest Period therefor, Convert into a Base Rate Loan, and
(4) the obligation of the Banks to make, or Continue Loans as, or to Convert
Loans into, LIBOR Loans shall be suspended until the Agent shall notify the
Borrower and the Banks that the circumstances causing such suspension no
longer exist.

            (b)   If, with respect to any LIBOR Loan, any Bank notifies the
Agent that LIBOR for any Interest Period will not adequately reflect the cost
to such Bank of making, funding or maintaining its respective LIBOR Loans for
such Interest Period, the Agent shall 





                                      -30-
<PAGE>   34
forthwith so notify the Borrower and the Banks, whereupon (1) each LIBOR Loan
will automatically, on the last day of the then-existing Interest Period
therefor, Convert into a Base Rate Loan, (2) any request for LIBOR Loans shall
be withdrawn or changed to a request for Base Rate Loans, at the discretion of
the Borrower, and (3) the obligation of the Banks to make, or Continue Loans as,
or to Convert Loans into, LIBOR Loans shall be suspended until the Agent shall
notify the Borrower and the Banks that the circumstances causing such suspension
no longer exist.

     SECTION 3.2. Additional Costs.

            (a)   The Borrower shall pay directly to each Bank from time to
time such amounts as such Bank may determine to be necessary to compensate
such Bank for any costs that such Bank determines are attributable to its
making or maintaining of any LIBOR Loans or its obligation to make any LIBOR
Loans hereunder, or any reduction in any amount receivable by such Bank
hereunder in respect of any of such Loans or such obligation (such increases
in costs and reductions in amounts receivable being herein called "Additional
Costs"), resulting from any Regulatory Change that:

                  (1)   shall subject any Bank (or its Applicable Lending
Office for any of such Loans) to any tax, duty or other charge in respect of
such Loans or its Notes or changes the basis of taxation of any amounts
payable to such Bank under this Agreement or its Notes in respect of any such
Loans (excluding changes in the rate of tax on the overall net income of such
Bank or of such Applicable Lending Office by the jurisdiction in which such
Bank has its principal office or such Applicable Lending Office); or

                  (2)   imposes or modifies any reserve, special deposit or
similar requirements (other than the reserve requirement utilized in the
determination of the Adjusted LIBOR for such Loan) relating to any extensions
of credit or other assets of, or any deposits with or other liabilities of,
such Bank (including, without limitation, any of such Loans or any deposits
referred to in the definition of "LIBOR" in Section 1.1 hereof), or any
commitment of such Bank (including, without limitation, the Advance
Commitments of such Bank hereunder); or

                  (3)   imposes any other condition affecting this Agreement
or its Notes (or any of such extensions of credit or liabilities) or its
Advance Commitments.

            (b)   Without limiting the effect of the provisions of
paragraph (a) of this Section 3.2, in the event that, by reason of any
Regulatory Change, any Bank either (1) incurs Additional Costs based on or
measured by the excess above a specified level of the amount of a category of
deposits or other liabilities of such Bank that includes deposits by
reference to which the interest rate on LIBOR Loans is determined as provided
in this Agreement or a category of extensions of credit or other assets of
such Bank that includes LIBOR Loans, or (2) becomes subject to restrictions
on the amount of such a category of liabilities or assets that it may hold,
then, if such Bank so elects by notice to the Borrower (with a copy to the
Agent), the obligation 





                                      -31-
<PAGE>   35

of such Bank to make or Continue, or to Convert Base Rate Loans into, LIBOR
Loans hereunder shall be suspended until such Regulatory Change ceases to be in
effect (in which case the provisions of Section 3.1 hereof shall be applicable).

            (c)   Without limiting the effect of the foregoing provisions of
this Section 3.2 (but without duplication), the Borrower shall pay directly
to each Bank from time to time on request such amounts as such Bank may
determine to be necessary to compensate such Bank (or, without duplication,
the bank holding company of which such Bank is a subsidiary) for any costs
that it determines are attributable to the maintenance by such Bank (or any
Applicable Lending Office or such bank holding company), pursuant to any law
or regulation or any interpretation, directive or request (whether or not
having the force of law and whether or not failure to comply therewith would
be unlawful) of any court or governmental or monetary authority (1) following
any Regulatory Change or (2) implementing any risk-based capital guideline or
other requirement (whether or not having the force of law and whether or not
the failure to comply therewith would be unlawful) heretofore or hereafter
issued by any government or governmental or supervisory authority
implementing at the national level the Basle Accord (including, without
limitation, the Final Risk-Based Capital Guidelines of the Board of Governors
of the Federal Reserve System (12 C.F.R. Part 208, Appendix A; 12 C.F.R. Part
225, Appendix A) and the Final Risk-Based Capital Guidelines of the Office of
the Comptroller of the Currency (12 C.F.R. Part 3, Appendix A)), of capital
in respect of its Advance Commitments or Loans (such compensation to include,
without limitation, an amount equal to any reduction of the rate or return on
assets or equity of such Bank (or any Applicable Lending Office or such bank
holding company) to a level below that which such Bank (or any Applicable
Lending Office or such bank holding company) could have achieved but for such
law, regulation, interpretation, directive or request).  For purposes of this
Section 3.2 and Section 3.4 hereof, "Basle Accord" shall mean the proposals
for risk-based capital framework described by the Basle Committee on Banking
Regulations and Supervisory Practices in its paper entitled "International
Convergence of Capital Measurement and Capital Standards" dated July 1988, as
amended, modified and supplemented and in effect from time to time or any
replacement thereof.

            (d)   Each Bank shall notify the Borrower of any event occurring
after the date of this Agreement entitling such Bank to compensation under
paragraph (a) or (c) of this Section 3.2 as promptly as practicable, but in
any event within 45 days, after such Bank obtains actual knowledge thereof;
provided that (1) if any Bank fails to give such notice within 45 days after
it obtains actual knowledge of such an event, such Bank shall, with respect
to compensation payable pursuant to this Section 3.2 in respect of any costs
resulting from such event, only be entitled to payment under this Section 3.2
for costs incurred from and after the date 45 days prior to the date that
such Bank does give such notice and (2) each Bank will designate a different
Applicable Lending Office for the Loans of such Bank affected by such event
if such designation will avoid the need for, or reduce the amount of, such
compensation and will not, in the sole opinion of such Bank, be
disadvantageous to such Bank, except that such Bank shall have no obligation
to designate an Applicable Lending Office located in the United States of
America.  Each Bank will furnish to the Borrower a certificate for
compensation under paragraph (a) or (c) 





                                      -32-
<PAGE>   36

of this Section 3.2. Determinations and allocations by any Bank for purposes of
this Section 3.2 of the effect of any Regulatory Change pursuant to paragraph
(a) or (b) of this Section 3.2, or of the effect of capital maintained pursuant
to paragraph (c) of this Section 3.2, on its costs or rate of return of
maintaining Loans or its obligation to make Loans, or on amounts receivable by
it in respect of Loans, and of the amounts required to compensate such Bank
under this Section 3.2, shall be conclusive, provided that such determinations
and allocations are made on a reasonable basis.

     SECTION 3.3. Compensation.  The Borrower shall pay to the Agent for
account of each Bank, upon the request of such Bank through the Agent, such
amount or amounts as shall be sufficient (in the reasonable opinion of such
Bank) to compensate it for any loss, cost or expense that such Bank determines
is attributable to:

            (a)   any payment, mandatory or optional prepayment or Conversion
of a LIBOR Loan made by such Bank for any reason (including, without
limitation, a mandatory prepayment of the Loans pursuant to Section 2.7(d) or
3.6 hereof or the acceleration of the loans pursuant to Section 10.1 hereof)
on a date other than the last day of the Interest Period for such Loan; or

            (b)   any failure by the Borrower for any reason (including,
without limitation, the failure of any of the conditions precedent specified
in Article 6 hereof to be satisfied) to borrow a LIBOR Loan from such Bank on
the date for such borrowing specified in the relevant request for borrowing
given pursuant to Section 4.6 hereof.

Without limiting the effect of the preceding sentence, such compensation
shall include an amount equal to the excess, if any, of (i) the amount of
interest that otherwise would have accrued on the principal amount so paid,
prepaid, Converted or not borrowed for the period from the date of such
payment, prepayment, Conversion or failure to borrow to the last day of the
then current Interest Period for such Loan (or, in the case of a failure to
borrow, the Interest Period for such Loan that would have commenced on the
date specified for such borrowing) at the applicable rate of interest for
such Loan provided for herein over (ii) the amount of interest that otherwise
would have accrued on such principal amount at a rate per annum equal to the
interest component of the amount such Bank would have bid in the London
interbank market for Dollar deposits of leading banks in amounts comparable
to such principal amount and with maturities comparable to such period (as
reasonably determined by such Bank).

     SECTION 3.4. Additional Costs in Respect of Letters of Credit.

            (a)   Without limiting the obligations of the Borrower under
Section 3.2 hereof (but without duplication), if as a result of any
Regulatory Change or any risk-based capital guideline or other requirement
heretofore or hereafter issued by any government or governmental or
supervisory authority implementing at the national level the Basle Accord
there shall be imposed, modified or deemed applicable any tax, reserve,
special deposit, capital adequacy or similar requirement against or with
respect to or measured by reference to Letters of Credit 





                                      -33-
<PAGE>   37

issued or to be issued hereunder and the result shall be to increase the cost to
any Bank or Banks of issuing (or purchasing participations in) or maintaining
its obligation hereunder to issue (or purchase participations in) any Letter of
Credit hereunder or reduce any amount receivable by any Bank hereunder in
respect of any Letter of Credit (which increases in cost, or reductions in
amount receivable, shall be the result of such Bank's or Banks' reasonable
allocation of the aggregate of such increases or reductions resulting from such
event), then, upon demand by such Bank or Banks (through the Agent), the
Borrower shall pay immediately to the Agent for account of such Bank or Banks,
from time to time as specified by such Bank or Banks (through the Agent), such
additional amounts as shall be sufficient to compensate such Bank or Banks
(through the Agent) for such increased costs or reductions in amount. A
statement as to such increased costs or reductions in amount incurred by any
such Bank or Banks, submitted by such Bank or Banks to the Borrower shall be
conclusive in the absence of manifest error as to the amount thereof.

            (b)   Each Bank shall notify the Borrower of any event occurring
after the date of this Agreement entitling such Bank to compensation under
paragraph (a) of this Section 3.4 as promptly as practicable, but in any
event within 45 days, after such Bank obtains actual knowledge thereof;
provided that (1) if any Bank fails to give such notice within 45 days after
it obtains actual knowledge of such an event, such Bank shall, with respect
to compensation payable pursuant to this Section 3.4 in respect of any costs
resulting from such event, only be entitled to payment under this Section 3.4
for costs incurred from and after the date 45 days prior to the date that
such Bank does give such notice and (2) each Bank will designate a different
Applicable Lending Office for the Letters of Credit participations of such
Bank affected by such event if such designation will avoid the need for, or
reduce the amount of, such compensation and will not, in the sole opinion of
such Bank, be disadvantageous to such Bank, except that such Bank shall have
no obligation to designate an Applicable Lending Office located in the United
States of America.  Each Bank will furnish to the Borrower a certificate for
compensation under paragraph (a) of this Section 3.4.  Determinations and
allocations by any Bank for purposes of this Section 3.4 of the effect of any
Regulatory Change pursuant to paragraph (a) of this Section 3.4, or of the
effect of capital maintained pursuant to paragraph (c) of Section 3.4, on its
costs or rate of return of issuing or participating in, or maintaining
Letters of Credit or its obligation to issue or participate in Letters of
Credit, or on amounts receivable by it in respect of Letters of Credit, and
of the amounts required to compensate such Bank under this Section 3.4, shall
be conclusive, provided that such determinations and allocations are made on
a reasonable basis.

     SECTION 3.5. U.S. Taxes.  The Borrower agrees to pay to each Bank
that is not a U.S. Person such additional amounts as are necessary in order
that the net payment of any amount due to any Bank that is a non-U.S. Person
hereunder after deduction for or withholding in respect of any U.S. Tax
imposed with respect to such payment (or in lieu thereof, payment of such
U.S. Tax by such non-U.S. Person), will not be less than the amount stated
herein to be then due and payable, provided that the foregoing obligation to
pay such additional amounts shall not apply:



                                      -34-
<PAGE>   38

            (a)   to any payment to a Bank hereunder unless such Bank is, on
the date hereof (or on the date it becomes a Bank as provided in Section
12.19 hereof) and on the date of any change in the Applicable Lending Office
of such Bank, either entitled to submit a Form 1001 (relating to such Bank
and entitling it to a complete exemption from withholding on all interest to
be received by it hereunder in respect of the Loans) or Form 4224 (relating
to all interest to be received by such Bank hereunder in respect of the
Loans), or

            (b)   to any U.S. Tax imposed solely by reason of the failure by
such non-U.S. Person to comply with applicable certification, information,
documentation or other reporting requirements concerning the nationality,
residence, identity or connections with the United States of America of such
non-U.S. Person if such compliance is required by statute or regulation of
the United States of America as a precondition to relief or exemption from
such U.S. Tax.

For the purposes of this Section 3.5, "Form 1001" shall mean Form 1001
(Ownership, Exemption, or Reduced Rate Certificate) of the Department of the
Treasury of the United States of America, "Form 4224" shall mean Form 4224
(Exemption from Withholding of Tax on Income Effectively Connected with the
Conduct of a Trade or Business in the United States) of the Department of the
Treasury of the United States of America (or in relation to either such Form
such successor and related forms as may from time to time be adopted by the
relevant taxing authorities of the United States of America to document a
claim to which such Form relates), "U.S. Person" shall mean a citizen,
national or resident of the United States of America, a corporation,
partnership or other entity created or organized in or under any laws of the
United States of America, or any estate or trust that is subject to Federal
income taxation regardless of the source of its income and "U.S. Taxes" shall
mean any present or future tax, assessment or other charge or levy imposed by
or on behalf of the United States of America or any taxing authority thereof
or therein.  Within 30 days after paying any amount to the Agent or any Bank
from which it is required by law to make any deduction or withholding, and
within 30 days after it is required by law to remit such deduction or
withholding to any relevant taxing or other authority, the Borrower shall
deliver to the Agent for delivery to such non-U.S. Person evidence
satisfactory to such Person of such deduction, withholding or payment (as the
case may be).  A certificate as to the amount of such increased cost or
additional tax, submitted to the Borrower and the Agent by such Bank, shall
be conclusive and binding for all purposes, absent manifest error.

     SECTION 3.6. Illegality.  Notwithstanding any other provision of
this Agreement, if any Bank shall notify the Agent that the introduction of
or any change in or in the interpretation of any law or regulation makes it
unlawful, or any central bank or other governmental authority asserts that it
is unlawful, for any Bank to perform its obligations hereunder to make LIBOR
Loans or to fund or maintain LIBOR Loans hereunder, (1) the obligation of the
Banks to make, to Continue Loans as or to Convert Loans or portions thereof
into LIBOR Loans, shall be suspended until the Agent shall notify the
Borrower and the Banks that the circumstances causing such suspension no
longer exist, and (2) the Borrower shall forthwith prepay in full all 




                                      -35-
<PAGE>   39

LIBOR Loans of all Banks then outstanding, together with interest accrued
thereon and any amount payable pursuant to Section 3.3.


                                     ARTICLE 4
                  PAYMENTS, COMPUTATIONS AND CERTAIN NOTICES

     SECTION 4.1. Payments.

            (a)   The Borrower shall make each payment hereunder and under
the Notes and the LC Agreements without setoff, deduction or counterclaim of
any kind not later than 11:00 a.m. (Bethesda, Md. time) on the day when due
in U.S. dollars to the Agent at its address referred to in Section 12.2 in
same day funds.  Except to the extent otherwise provided herein, the Agent
will promptly thereafter cause to be distributed like funds relating to the
payment of principal or interest on the Advances, the Acquisition Loans or
fees ratably to the Banks for the account of their respective Applicable
Lending Offices, and like funds relating to the payment of any other amount
payable to any Bank to such Bank for the account of its Applicable Lending
Office, in each case to be applied in accordance with the terms of this
Agreement.

            (b)   If any payment of principal, interest or fees is not made
within ten days of its due date, the Borrower agrees to pay to the Agent, for
the ratable benefit of the Banks, a late charge equal to 5% of the amount of
the payment, provided that the foregoing shall not constitute a waiver of the
right of the Agent or the Majority Banks to declare an Event of Default under
Section 10.1(a).  Upon the occurrence of an Event of Default and during the
continuation of such Event of Default, interest shall accrue on the Loans and
the Letter of Credit Obligations representing amounts paid by the Agent under
a Letter of Credit for which it has not been reimbursed, and the fee on the
undrawn Letters of Credit shall accrue, at a per annum rate of 2% above the
rate otherwise in effect.

            (c)   Whenever any payment hereunder or under the Notes shall be
stated to be due on a day other than a Business Day, such payment shall be
made on the next succeeding Business Day, and such extension of time shall in
such case be included in the computation of payment of interest or fee, as
the case may be; provided, however, if such extension would cause payment of
interest on or principal of LIBOR Loans to be made in the next following
calendar month, such payment shall be made on the next preceding Business Day.

     SECTION 4.2. Commitment Fees.  In consideration of the Loans to be made by
the Banks, the Borrower agrees to pay to the Agent for the ratable benefit of
each Bank a commitment fee equal to the Applicable Unused Fee Percentage per
annum on the daily aggregate unused amount of the Advance Commitment (for which
purpose the use of the Advance Commitment shall include the outstanding amount
of Advances and Letters of Credit).  The fees provided for in this Section 4.2
shall be calculated and shall be payable quarterly in arrears on each Quarterly
Payment Date, commencing with the first such date to occur after the Closing
Date and on the Advance Termination Date.




                                      -36-

     SECTION 4.3. Agent's Fee.  [INTENTIONALLY DELETED]

     SECTION 4.4. Computations.  All computations of interest, fees and other
charges hereunder and under any Loan Document shall be made by the Agent on the
basis of a year of 360 days, in each case for the actual number of days
(including the first day but excluding the last day) occurring in the period
for which such interest or other amounts are payable.  Each determination by
the Agent of an interest rate or fees hereunder shall be conclusive and binding
for all purposes, absent manifest error.

     SECTION 4.5. Minimum Amounts.  Except for mandatory prepayments
made pursuant to Section 2.7(d) hereof and Conversions or prepayments made
pursuant to Sections 3.1, 3.2 and 3.6 hereof, each borrowing, Conversion and
partial prepayment of principal of Loans shall be in an aggregate amount at
least equal to $500,000 or a larger multiple of $100,000 (borrowings,
Conversions or prepayments of or into Loans of different Types or, in the
case of LIBOR Loans, having different Interest Periods at the same time
hereunder to be deemed separate borrowings, Conversions and prepayments for
purposes of the foregoing, one for each Type or Interest Period), provided
that the aggregate principal amount of LIBOR Loans having the same Interest
Period shall be in an amount at least equal to $500,000 or a larger multiple
of $100,000 and, if any LIBOR Loans would otherwise be in a lesser principal
amount for any period, such Loans shall be Floating LIBOR Loans during such
period.

     SECTION 4.6. Certain Notices.  In addition to written request for
the Oasis Acquisition Loan required by Section 2.4, notices by the Borrower
to the Agent of terminations or reductions of the Advance Commitments, of
borrowings, Conversions, Continuations and optional prepayments of Loans and
of Types of Loans and of the duration of Interest Periods shall be in

     SECTION 4.7. Non-Receipt of Funds by the Agent.  Unless the Agent
shall have been notified by a Bank or the Borrower (the "Payor") prior to the
date on which the Payor is to make payment to the Agent of (in case of a
Bank) the proceeds of a Loan to be made by such Bank hereunder or (in the
case of the Borrower) a payment to the Agent for account of one or more of
the Banks hereunder (such payment being herein called the "Required
Payment"), which notice shall be effective upon receipt, that the Payor does
not intend to make the Required Payment to the Agent, the Agent may assume
that the Required Payment has been made and may, in reliance upon such
assumption (but shall not be required to), make the amount thereof available
to the intended recipient(s) on such date; and, if the Payor has not in fact
made payment, the recipient shall, on demand, repay to the Agent the amount
so made available together with interest thereon in respect of each day
during the period commencing on the date (the "Advance Date") such amount was
so made available by the Agent until the date the Agent recovers such amount
at a rate per annum equal to the Federal Funds Rate for such day and, if such
recipient(s) shall fail promptly to make such payment, the Agent shall be
entitled to recover such amount, on demand, from the Payor, together with
interest as aforesaid, provided that if neither the recipient(s) nor the
Payor shall return the Required Payment to the Agent within five Business
Days of the Advance Date, the Payor and the recipient(s) shall each be
obligated to pay interest on the Required Payment from and after such fifth
Business Day as follows:

            (a)   if the Required Payment shall represent a payment to be
made by the Borrower to the Banks, the Borrower and the recipient(s) shall
each be obligated to pay interest in respect of the Required Payment at a
rate per annum equal to the Base Rate in effect from time to time plus 2%
(and, in case the recipient(s) shall return the Required Payment to the
Agent, without limiting the obligation of the Borrower under Section 4.1(b)
hereof to pay interest to such recipient(s) at the default rate in respect of
the Required Payment); and

            (b)   if the Required Payment shall represent proceeds of a Loan
to be made by the Banks to the Borrower, the Payor and the Borrower shall
each be obligated to pay interest in respect of the Required Payment at a
rate per annum equal to the Base Rate in effect from time to time plus 2%
(and, in case the Borrower shall return the Required Payment to the Agent,
without limiting any claim the Borrower may have against the Payor in respect
of the Required Payment).

     SECTION 4.8. Sharing of Payments, etc.  Except to the extent
otherwise expressly provided herein, (a) Advances and the Oasis Acquisition
Loan shall be made by the Banks pro rata in accordance with their respective
Commitment Percentages, (b) each reduction in the Advance Commitment shall be
made pro rata in accordance with the respective amounts thereof, (c) each
payment or prepayment of the principal of or interest on the Advances and the
Oasis Acquisition Loan or of fees shall be made for the account of the Banks
pro rata in accordance with the respective amounts thereof then due and
payable and held by them, provided that if immediately prior to giving effect
to any such payment the outstanding principal amount of Advances and the
Oasis Acquisition Loan shall not be held by the Banks pro rata in accordance
with their respective Commitment Percentage, then such payment shall be
applied to such Loans in such manner as shall result, as nearly as
practicable, in the outstanding principal amount of such Loans being held pro
rata in accordance with their respective Commitment Percentage, (d) the
making, Conversion and Continuation of Advances and the Oasis Acquisition
Loan of a particular Type (other than Conversions provided for in
Sections 3.1, 3.2 and 3.6) shall be made pro rata among the Banks in
accordance with their respective Commitment Percentage and the then current
Interest Period for each Bank's portion of each Loan of such Type shall be
conterminous; and (e) the Bank's participations in, and payment obligations
in respect of, Letters of Credit shall be pro rata in accordance with their
respective Commitment Percentage. If any Bank shall obtain any payment
(whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) on account of the Advances made by it or on account of
its share of the Oasis Acquisition Loan (other than pursuant to Sections 3.2,
3.3, 3.4 and 3.5) in excess of its ratable share of payments on account of
the Advances or the Oasis Acquisition Loan obtained by all the Banks, such
Bank shall forthwith purchase from the other Banks such participations in the
Advances made by them or in the Oasis Acquisition Loan as shall be necessary
to cause such purchasing Bank to share the excess payment ratably with each
of them; provided, however, that if all or any portion of such excess payment
is thereafter recovered from such purchasing Bank, such purchase from each
Bank shall be rescinded and such Bank shall repay to the purchasing Bank the
purchase price to the extent of such recovery together with an amount equal
to such Bank's ratable share (according to the proportion of (1) the amount
of such Bank's required repayment to (2) the total amount so recovered from
the purchasing Bank) of any interest or other amount paid or payable by the
purchasing Bank in respect of the total amount so recovered.  The Borrower
agrees that any Bank so purchasing a participation from another Bank pursuant
to this Section 4.8 may, to the fullest extent permitted by law, exercise all
of its rights of payment (including the right of set-off) with respect to
such participation as fully as if such Bank were the direct creditor of the
Borrower in the amount of such participation.

     SECTION 4.9. Several Obligations.  No Bank shall be responsible
for the failure of any other Bank to make a Loan or to perform any other
obligation to be made or performed by such other Bank hereunder, and the
failure of any Bank to make a Loan or to perform any other obligation to be
made or performed by it hereunder shall not relieve the obligation of any
other Bank to make any Loan or to perform any other obligation to be made or
performed by such other Bank.

Credit Obligation, (b) the amount of any principal, interest and fee due and
payable or to become due and payable hereunder, and (c) the amount of any sum
received by the Agent hereunder.  The entries maintained in such accounts
shall be prima facie evidence of the existence of the amounts recorded
therein, provided that the failure of the Agent to maintain such accounts or
any error therein shall not in any manner affect the obligation of the
Borrower to repay all amounts owed by it in accordance with the terms of this
Agreement and the other Loan Documents.

     SECTION 4.11. Crediting of Payments and Proceeds.  In the event
that the Borrower shall fail to pay any of the Obligations when due and the
Obligations have been accelerated pursuant to Section 10.1, all payments
received by the Banks upon the Notes and the other Obligations and all net
proceeds from the enforcement of the Obligations shall be applied first to
all expenses then due and payable by the Borrower hereunder, then to all
indemnity obligations then due and payable by the Borrower hereunder, then to
all Agent's fees then due and payable, then to all other fees and commissions
then due and payable, then to accrued and unpaid interest on the Revolving
Notes, the Oasis Acquisition Note and the Letter of Credit Obligations (pro
rata in accordance with all such amounts due), then to the principal amount
of the Revolving Notes, the Oasis Acquisition Note and the Letter of Credit
Obligations, and then to the cash collateral account described in Section
10.l to the extent of any Letters of Credit then outstanding, in that order.

others for the purpose of purchasing or carrying any margin stock.

pension benefit plan" (as defined in Section 3(2) of ERISA) established or
maintained by the Borrower or any Subsidiary. None of the employee pension
benefit plans (as defined above) of the Borrower or any Subsidiary, nor any
trusts created thereunder, nor any trustee or administrator thereof, has engaged
in a "prohibited transaction," as such term is defined in Section 406 of ERISA
or Section 4975 of the Code, that could subject such plans or 


                                       -46-
<PAGE>   50

any of them, any such trust, or any trustee or administrator thereof, or any
party dealing with such plans or any such trust to any material liability or tax
or penalty on prohibited transactions imposed by such Sections 406 or 4975.
Neither the Borrower nor any Affiliate or Subsidiary of the Borrower is now, or
at any time in the past has been, obligated to make contributions to a
"multiemployer plan," as such term is defined in Section 4001(a)(3) of ERISA.

            (k)   Taxes.  The Borrower and each Subsidiary has filed all tax
returns (federal, state and local) required to be filed and have paid all
taxes, assessments and governmental charges and levies shown thereon to be
due, including interest and penalties, and the charges, accruals and reserves
on the books of the Borrower in respect thereof are, in the opinion of the
Borrower, adequate.  Neither the Borrower nor any Subsidiary has given or
been requested to give a waiver of the statute of limitations relating to the
payment of any taxes.

            (l)   Debt.  The Borrower and its Subsidiaries are not in any
manner directly or contingently obligated with respect to any Debt that is
not permitted by this Agreement.  Neither the Borrower nor any Subsidiary is
in default with respect to any Debt.

            (m)   Debarment and Suspension.  No event has occurred and no
condition exists that is likely to result in the debarment or suspension of
the Borrower or any Subsidiary from any contracting with the Government, and
the Borrower has not, nor has any Affiliate or Subsidiary of the Borrower,
been subject to any such debarment or suspension prior to the date of this
Agreement.

            (n)   Material Contracts.  Attached hereto as Schedule 7.1(n) is
a correct and complete list, as of the date of this Agreement, of each
Material Contract.  Neither the Borrower, any Subsidiary nor any other party
thereto is in material default under any Material Contract.

            (o)   Intellectual Property.  The Borrower and its Subsidiaries
do not own or hold any Intellectual Property subject to United States
copyright, patent or trademark protection, other than as listed on
Schedule 7.1(o) attached hereto, and all of such Intellectual Property has
been registered with the United States Patent and Trademark Office and the
Register of Copyrights.  The Borrower and each Subsidiary owns or has the
right to use under valid license agreements or otherwise all Intellectual
Property that is required or necessary for the conduct of the business of the
Borrower and its Subsidiaries as now conducted or proposed to be conducted
without any conflict with any rights of any other Person.

            (p)   Compliance with Laws.  The Borrower and each Subsidiary are
in compliance in all material respects with all applicable laws and
regulations.

            (q)   True and Complete Information.  All factual and financial
information (taken as a whole) previously furnished to the Banks in
connection with this Agreement by the Borrower and each Subsidiary is, and
all factual and financial information (taken as a whole) furnished to the
Banks by the Borrower and each Subsidiary after the date of this Agreement
will be, true and accurate in all material respects on the date on which such
information is dated, 



                                       -47-
<PAGE>   51

certified or furnished, and is not, and will not be, incomplete by omitting to
state any fact necessary to make such information (taken as a whole) not
misleading at such time in light of the circumstances under which such
information was provided.

            (r)   Integrated Business.  The Borrower and its Subsidiaries
will be engaged as an integrated group in providing services and goods to
their respective Customers.  The integrated operation will require financing
on such a basis that credit supplied to the Borrower be made available from
time to time to Subsidiaries of the Borrower, as required for the successful
operation of the Borrower and its Subsidiaries separately, and the integrated
operation as a whole.  In that connection, the Borrower and its Subsidiaries
will request that the Agent and the Banks provide the Loans to, and issue the
Letters of Credit for the account of, the Borrower (to be made available as
needed to the Subsidiaries) to finance such operation.  To induce the Agent
and the Banks to extend credit, each Subsidiary will execute and deliver to
the Agent a Security Agreement, a Subsidiary Guaranty, an Intellectual
Property Assignment, and, if applicable, Mortgages for all Real Estate
Assets.  Each Subsidiary will derive benefit, directly and indirectly, from
the credit so extended to the Borrower, both in its separate capacity and as
a member of the integrated group.

            (s)   Environmental Laws.  The Borrower and its Subsidiaries have
obtained all governmental approvals which are required under Environmental
Laws, and are in compliance with all terms and conditions of such
governmental approvals, which the failure to obtain or to comply with could
reasonably be expected to have a Material Adverse Effect.  Each of the
Borrower and its Subsidiaries is also in compliance with all other
limitations, restrictions, conditions, standards, prohibitions, requirements,
obligations, schedules, and timetables contained in the Environmental Laws
the failure with which to comply could have a Material Adverse Effect.
Neither the Borrower nor any Subsidiary is aware of, or has received notice
of, any past, present, or future events, conditions, circumstances,
activities, practices, incidents, actions, or plans which, with respect to
the Borrower or any of its Subsidiaries may interfere with or prevent
compliance or continued compliance with Environmental Laws, or may give rise
to any common-law or legal liability, or otherwise form the basis of any
claim, action, demand, suit, proceeding, hearing, study, or investigation,
based on or related to the manufacture, processing, distribution, use,
treatment, storage, disposal, transport or handling or the emission,
discharge, release or threatened release into the environment, of any
pollutant, contaminant, chemical, or industrial, toxic, or other Hazardous
Material that could be reasonably expected to have a Material Adverse Effect;
and there is no civil, criminal, or administrative action, suit, demand,
claim, hearing, notice, or demand letter, notice of violation, investigation,
or proceeding pending or, to the knowledge of the Borrower or any Subsidiary,
after due inquiry, threatened, against the Borrower or any of its
Subsidiaries relating in any way to Environmental Laws that could be
reasonably expected to have a Material Adverse Effect.

            (t)   Investment Company; Public Utility Holding Company.
Neither the Borrower nor any Subsidiary is an "investment company" within the
meaning of the Investment Company Act of 1940.  Neither the Borrower nor any
Subsidiary is (i) a "holding company" or a 



                                       -48-
<PAGE>   52

"subsidiary company" of a "holding company," or an "affiliate" of a "holding
company" or of a "subsidiary company" of a "holding company," within the meaning
of the Public Utility Holding Company Act of 1935, as amended, or (ii) subject
to any other Applicable Law which purports to regulate or restrict its ability
to borrow money or to consummate the transactions contemplated by this Agreement
or to perform its obligations under any Loan Document to which it is a party.

            (u)   Year 2000.  The Borrower and its Subsidiaries have
undertaken reasonable efforts to determine whether all material Date Affected
Information Technology used in the business operations of the Borrower and
its Subsidiaries is Fully Date Capable, and, to the extent necessary, the
Borrower and its Subsidiaries have initiated efforts to make Date Affected
Information Technology Fully Date Capable prior to the date that the failure
to be Fully Date Capable would adversely affect the operation thereof.  For
purposes of this Agreement, Date Affected Information Technology is
"material" if the failure or degradation in performance of such Date Affected
Information Technology would result in a Material Adverse Effect.

            (v)   Employee Relations.  As of the Closing Date, neither the
Borrower nor any of its Subsidiaries is a party to any collective bargaining
agreement nor has any labor union been recognized as the representative of
its employees except as set forth on Schedule 7.1(v).  The Borrower knows of
no pending, threatened or contemplated strikes, work stoppage or other
collective labor disputes involving its employees or those of any of its
Subsidiaries, except for those which are not reasonably likely to have a
materially adverse effect on the operations of the Borrower or any Subsidiary.

            (w)   Burdensome Provisions.  Neither the Borrower nor any
Subsidiary is a party to any indenture, agreement, lease or other instrument,
or subject to any corporate or partnership restriction, governmental approval
or applicable law which is so unusual or burdensome as in the foreseeable
future could be reasonably expected to have a Material Adverse Effect.  The
Borrower and its Subsidiaries do not presently anticipate that future
expenditures needed to meet the provisions of any statutes, orders, rules or
regulations of a governmental authority will be so burdensome as to have a
Material Adverse Effect.

            (x)   No Material Adverse Change.  Since March 31, 1998, there
has been no material adverse change in the business or financial condition of
the Borrower or any Subsidiary, and no event has occurred or condition arisen
that could reasonably be expected to have a Material Adverse Effect.

            (y)   Absence of Defaults.  No event has occurred and is
continuing which constitutes a Default or an Event of Default.  No event has
occurred and is continuing which constitutes, or which with the passage of
time or giving of notice or both would constitute, a default or event of
default by the Borrower or any Subsidiary under any Material Contract or
judgment, decree or order to which the Borrower or one or more of its
Subsidiaries is a party or by which the Borrower or one or more of its
Subsidiaries or any of their respective properties may be bound or which
would require the Borrower or one or more of its Subsidiaries to make any
payment thereunder prior to the scheduled maturity date therefor.

satisfactory to the Banks prior to such move or change.

and (2) all lawful claims of materialmen, mechanics, carriers, warehousemen and
landlords for labor, materials, supplies and rentals which, if unpaid, might

Section shall not require the payment or discharge of any such tax, assessment,
charge, levy or claim which is being contested in good faith by appropriate
proceedings which operate to suspend the collection thereof and for which
adequate reserves have been established on the books of the Borrower or such
Subsidiary, as applicable, in accordance with GAAP.

            (l)   Environmental Matters.  Comply, and cause all of its
Subsidiaries to comply, with all Environmental Laws, the failure with which
to comply could have a Material Adverse Effect.  If a Borrower or any
Subsidiary shall (1) receive notice that any violation of any Environmental
Law may have been committed or is about to be committed by such Person,
(2) receive notice that any administrative or judicial complaint or order has
been filed or is about to be filed against a Borrower or any Subsidiary

party alleging that a Borrower or any Subsidiary may be liable or responsible
for costs associated with a response to or cleanup of a release of Hazardous
Materials or any damages caused thereby, and such notices, individually or in
the aggregate, could have a Material Adverse Effect, such Borrower shall
provide the Agent with a copy of such notice within 10 days after the receipt
thereof by such Borrower or any of the Subsidiaries.  The Borrower and the
Subsidiaries shall promptly take all actions necessary to prevent the
imposition of any Liens on any of their respective properties arising out of
or related to any Environmental Laws.

            (m)   Mortgages.  Not later than 30 days after the date the Agent
gives notice (the "Mortgage Notice") to the Borrower requesting the granting
of Mortgages on Real Estate of the Borrower and its Subsidiaries , the
Borrower (1) will and will cause each of the applicable Subsidiaries to duly
execute, acknowledge and deliver Mortgages to the Agent in form and substance
satisfactory to the Agent, in recordable form (including full legal
descriptions of the Real Estate) and in such number of copies as the Agent
shall have requested and (2) will furnish or cause to be furnished to the
Agent:

      acceptable to the Agent (the "Title Policies") issued to the Agent by
      such title insurance company as the Agent shall approve (the "Title
      Insurer"), in form and substance and in such amounts satisfactory to
      the Agent, insuring the perfection, enforceability and first priority
      of the Lien of each of the Mortgages subject only to such title
      exceptions as the Agent in the exercise of its reasonable discretion
      shall approve and including such affirmative coverage and endorsements
      as the Agent shall require, together with copies of (A) all instruments
      of record and (B) all other documents specified in the Title Policies
      encumbering or otherwise affecting the Real Estate;

      appropriate, by the trustee designated therein (such trustee to be
      specified by the Borrower with the approval of the Agent), and that
      such trustee has full power and authority to serve in such capacity and
      to exercise all rights and powers under such Mortgages and (B) the
      Mortgages are legal, valid and binding obligations enforceable in
      accordance with their respective terms except as may be limited by
      (x) bankruptcy, insolvency, reorganization, moratorium or similar laws
      of general applicability affecting the enforcement of creditor's rights
      and (y) general principles of equity (regardless of whether such
      enforceability is considered in a proceeding in equity or at law) and
      opining as to such other matters with respect to the Mortgages as such
      special counsel to the Agent may require;

            (q)   Any indorsement or guaranty of the payment of the Loans
shall cease for any reason to be in full force and effect, or any indorser or
guarantor shall contest the validity or enforceability of the indorsement or
guaranty or deny that it has any further liability or obligation under the
indorsement or guaranty; or

            (r)   The failure of the Borrower to give notice of the
termination of the Epson Contract within 5 days after notice to or from Epson
of said termination.

     SECTION 10.2. Remedies.  Upon the occurrence of any Event of Default, the
Agent (a) shall at the request of the Majority Banks, by notice to the
Borrower, terminate the Commitments, whereupon the same shall forthwith
terminate, and (b) shall at the request of the Majority Banks, by notice to the
Borrower, declare the Notes, the Loans, the Letter of Credit Obligations and
all other Obligations, all interest thereon and all other amounts payable under
this Agreement, to be forthwith due and payable, whereupon the Obligations, all
such interest and all such amounts shall become and be forthwith due and
payable, without presentment, demand, protest or further notice of any kind,
all of which are hereby expressly waived by the Borrower; provided, however,
that if an Event of Default occurs under Sections 10.1() or 10.1() above, (1)
Commitments shall automatically be terminated, and (2) the Obligations, all
such interest and all such amounts shall automatically become and be due and
payable, without presentment, demand, protest or any notice of any kind, all of
which are hereby expressly waived by the Borrower.  After the occurrence of an
Event of Default, the Agent may require the Borrower to pay, and the Borrower
agrees to pay, to the Agent an amount of cash equal to the aggregate amount of
the Letters of Credit then outstanding, and any amounts paid by the Borrower
shall be held by the Agent in a cash collateral account for the benefit of the
Banks, over which the Agent shall have the exclusive power of withdrawal, as
security for the Letter of Credit Obligations.

                                    THE AGENT
                                   ----------

     SECTION 11.1. Authorization and Action.  Each Bank hereby
appoints and authorizes the Agent to take such action as agent on its behalf
and to exercise such powers under this Agreement as are delegated to the
Agent by the terms hereof, together with such powers as are reasonably
incidental thereto.  The Agent shall not have any fiduciary duty to any Bank
or Loan Party.  As to any matters not expressly provided for by this
Agreement (including, without limitation, enforcement or collection of the
Notes), the Agent shall not be required to exercise any discretion or take
any action, but shall be required to act or to refrain from acting (and shall
be fully protected in so acting or refraining from acting) upon the
instructions of the Majority Banks, and such instructions shall be binding
upon all Banks and all holders of Notes; provided, however, that the Agent
shall not be required to take any action that exposes the Agent to personal
liability or that is contrary to this Agreement, any other Loan Document or
applicable 



                                     -65-

law. The Agent agrees to give to each Bank prompt notice of each notice given to
it by the Borrower pursuant to the terms of this Agreement.

     SECTION 11.2. Agent's Reliance.  Neither the Agent nor any of its
directors, officers, agents or employees shall be liable for any action taken
or omitted to be taken by it or them under or in connection with this
Agreement, except for its or their own gross negligence or willful
misconduct.  Without limitation of the generality of the foregoing, the
Agent:  (1) may treat the payee of any Note as the holder thereof; (2) may
consult with legal counsel (including counsel for the Borrower), independent
public accountants and other experts selected by it and shall not be liable
for any action taken or omitted to be taken in good faith by it in accordance
with the advice of such counsel, accountants or experts; (3) makes no
warranty or representation to any Bank and shall not be responsible to any
Bank for any statements, warranties or representations (whether written or
oral) made in or in connection with this Agreement or any other Loan
Document; (4) shall not have any duty to ascertain or to inquire as to the
performance or observance of any of the terms, covenants or conditions of
this Agreement or any other Loan Document on the part of the Borrower or any
other Loan Party or to inspect the property (including the books and records)
of the Borrower or any other Loan Party; (5) shall not be responsible to any
Bank for the due execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement, any other Loan Document or any other
instrument or document furnished pursuant hereto; and (6) shall incur no
liability under or in respect of this Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by
telecopier, telegram, cable or telex) reasonably believed by it to be genuine
and signed or sent by the proper party or parties.

     SECTION 11.3. NationsBank and Affiliates.  With respect to its
Advance Commitment and Oasis Acquisition Loan Commitment, the Advances and
Oasis Acquisition Loan made by it, the Notes issued to it and the Obligations
due to it, NationsBank, N.A. shall have the same rights and powers under this
Agreement as any other Bank and may exercise the same as though it were not
the Agent, and the term "Bank" or "Banks" shall, unless otherwise expressly
indicated, include NationsBank, N.A. in its individual capacity.
NationsBank, N.A.and its affiliates may accept deposits from, lend money to,
act as trustee under indentures of, and generally engage in any kind of
business with, the Borrower and any Person who may do business with or own
common stock of the Borrower, all as if NationsBank, N.A. were not the Agent
and without any duty to account therefor to the Banks.

     SECTION 11.4. Bank Credit Decision.  Each Bank acknowledges that
it has, independently and without reliance upon the Agent or any other Bank
and based on the financial statements referred to in Section 7.1(e) and such
other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement.  Each Bank also
acknowledges that it will, independently and without reliance upon the Agent
or any other Bank and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement.



                                     -66-
<PAGE>   70

     SECTION 11.5. Indemnification.  The Banks agree to indemnify the
Agent (to the extent not reimbursed by the Borrower), ratably according to
the respective principal amounts of the Notes then held by each of them (or
if no Notes are at the time outstanding or if any Notes are held by Persons
that are not Banks, ratably according to the respective amounts of their
Advance Commitment or Oasis Acquisition Loan Commitment), from and against
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever that may be imposed on, incurred by, or asserted against the Agent
in any way relating to or arising out of this Agreement or any action taken
or omitted by the Agent under this Agreement, provided that no Bank shall be
liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the Agent's gross negligence or willful misconduct.  Without
limitation of the foregoing, each Bank agrees to reimburse the Agent promptly
upon demand for its ratable share of any out-of-pocket expenses (including
counsel fees) incurred by the Agent in connection with the preparation,
execution, delivery, administration, modification, amendment or enforcement
(whether through negotiations, legal proceedings or otherwise) of, or legal
advice in respect of rights or responsibilities under, this Agreement, to the
extent that the Agent is not reimbursed for such expenses by the Borrower.

     SECTION 11.6. Successor Agent.  The Agent may resign at any time
by giving written notice thereof to the Banks and the Borrower.  Upon any
such resignation, the Majority Banks shall have the right to appoint a
successor Agent.  If no Event of Default has occurred and is continuing, the
Borrower shall have the right to approve a successor Agent, which approval
shall not be unreasonably withheld.  If no successor Agent shall have been so
appointed by the Majority Banks, and shall have accepted such appointment,
within 30 days after the retiring Agent's giving of notice of resignation,
then the retiring Agent, on behalf of the Banks, may appoint a successor
Agent, which shall be a commercial bank organized under the laws of the
United States of America or of any State thereof and having a combined
capital and surplus of at least $50,000,000.  Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent
shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations under this Agreement.  After any
retiring Agent's resignation hereunder as Agent, the provisions of this
Article 11 shall inure to its benefit as to any actions taken or omitted to
be taken by it while it was Agent under this Agreement.

                                  MISCELLANEOUS
                                  -------------

     SECTION 12.1. Amendments, Etc..  Except as otherwise expressly provided in
this Agreement, any consent or approval required or permitted by this Agreement
or in any Loan Document to be given by the Banks may be given, and any term of
this Agreement or of any other Loan Document may be amended, and the
performance or observance by the Borrower or any Subsidiary of any terms of
this Agreement or such other Loan Document or the continuance 



                                     -67-
<PAGE>   71

of any Default or Event of Default may be waived (either generally or in a
particular instance and either retroactively or prospectively) with, but only
with, the written consent of the Majority Banks (and, in the case of an
amendment to any Loan Document, the written consent of the Borrower).
Notwithstanding the foregoing, no amendment, waiver or consent shall, unless in
writing, and signed by all of the Banks (or the Agent at the written direction
of all of the Banks), do any of the following: (a) increase the Commitments of
the Banks or subject the Banks to any additional obligations; (b) reduce the
principal of, or interest rates that have accrued or that will be charged on the
outstanding principal amount of, any Loans or other Obligations; (c) reduce the
amount of any fees payable hereunder; (d) postpone any date fixed for any
payment of any principal of, interest on, or fees with respect to, any Loans or
any other Obligations; (e) change the Commitment Percentages; (f) amend this
Section or amend the definitions of the terms used in this Agreement or the
other Loan Documents insofar as such definitions affect the substance of this
Section; (g) release any Subsidiary from its obligations under a Subsidiary
Guaranty; (h) modify the definition of the term "Majority Banks" or modify in
any other manner the number or percentage of the Banks required to make any
determinations or waive any rights hereunder or to modify any provision hereof;
(i) release any Collateral; or (j) amend the definitions of "Borrowing Base" or
"Eligible Receivables." Further, no amendment, waiver or consent unless in
writing and signed by the Agent, or by NationsBank, N.A. in its capacity as the
issuer of the Letters of Credit, in addition to the Banks required above to take
such action, shall affect the rights or duties of the Agent, or NationsBank,
N.A. as such issuer under this Agreement or any of the other Loan Documents. No
waiver shall extend to or affect any obligation not expressly waived or impair
any right consequent thereon and any amendment, waiver or consent shall be
effective only in the specific instance and for the specific purpose set forth
therein. No course of dealing or delay or omission on the part of the Agent or
any Bank in exercising any right shall operate as a waiver thereof or otherwise
be prejudicial thereto. Except as otherwise explicitly provided for herein or in
any other Loan Document, no notice to or demand upon a Borrower shall entitle
such Borrower to other or further notice or demand in similar or other
circumstances.

     SECTION 12.2. Notices, Etc.  All notices and other communications
provided for hereunder shall be in writing (including telecopier,
telegraphic, telex or cable communication) and mailed, telecopied,
telegraphed, telexed, cabled or delivered by hand or sent, prepaid, by
Federal Express (or a comparable overnight delivery service), if to the
Borrower, at its address at 3601 Eisenhower Avenue, Alexandria, Virginia
22304, Attention:  Chief Financial Officer, if to any Bank or to the Agent,
at its Applicable Lending Office specified below its name on the signature
page hereto or in the Assignment and Assumption Agreement pursuant to which
such Bank becomes a party hereto; or, as to each party, at such other address
as shall be designated by such party in a written notice to the other
parties.  Any such notice or other communication, when mailed, telecopied,
telegraphed, telexed, cabled, delivered by hand or sent overnight, shall be
effective on the earliest of (a) the date it is actually received or
telecopied, telexed (confirmed by telex answerback), or delivered by hand,
(b) the Business Day after the day on which it is properly delivered to a
telegraph or cable company or to Federal Express (or a comparable 



                                     -68-
<PAGE>   72

overnight delivery service), as applicable, or (c) the third Business Day after
the day on which it is deposited in the United States mail.

     SECTION 12.3. No Waiver; Remedies.  No failure on the part of any
Bank or the Agent to exercise, and no delay in exercising, any right under
any Loan Document shall operate as a waiver thereof; nor shall any single or
partial exercise of any such right preclude any other or further exercise
thereof or the exercise of any other right.  The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

     SECTION 12.4. Captions.  The captions of the various sections and
paragraphs of this Agreement have been inserted only for the purposes of
convenience; such captions are not a part of this Agreement and shall not be
deemed in any manner to modify, explain, enlarge or restrict any of the
provisions of this Agreement.

     SECTION 12.5. Survival of Agreements.  All agreements,
representations and warranties made herein shall survive the delivery of this
Agreement, the making of the Loans and the issuance of the Letters of Credit
hereunder.

     SECTION 12.6. Cost, Expenses and Taxes. The Borrower agrees
(a) to pay or reimburse the Agent on demand for all its costs and expenses
incurred in connection with the preparation, execution and delivery of, and
any amendment, supplement or modification to, the Loan Documents and any
other documents prepared in connection herewith or therewith, and the
consummation of the transactions contemplated hereby and thereby, including,
without limitation, the reasonable fees and disbursements of counsel to the
Agent; (b) to pay or reimburse the Agent and each Bank for all of their
respective costs and expenses incurred in connection with the enforcement or
preservation of any rights under the Loan Documents and any such other
documents, including, without limitation, reasonable fees and disbursements
of counsel to the Agent and each Bank; and (c) to pay, indemnify and hold
each Bank and the Agent harmless from any and all recording and filing fees
and any and all liabilities with respect to, or resulting from any delay in
paying, stamp, excise and other taxes, if any, that may be payable or
determined to be payable in connection with the execution and delivery or
consummation of any of the transactions contemplated by, or any amendment,
supplement or modification to, or any waiver or consent under or in respect
of, the Loan Documents and any such other documents.

     SECTION 12.7. Indemnification.

            (a)   The Borrower shall and hereby agrees to indemnify, defend
and hold harmless each Agent, any affiliate of each Agent and each of the
Banks and their respective directors, officers, shareholders, agents,
employees and counsel (each referred to herein as an "Indemnified Party")
from and against any and all losses, costs, claims, damages, liabilities,
deficiencies, judgments or expenses of every kind and nature (including,

incurred 



                                     -69-
<PAGE>   73

by an Indemnified Party in connection with, arising out of, or by reason of, any
suit, cause of action, claim, arbitration, investigation or settlement, consent
decree or other proceeding (the foregoing referred to herein as an "Indemnity
Proceeding") arising out of: (i) this Agreement or any other Loan Document or
the transactions contemplated thereby, (ii) the making of any Loans hereunder;
(iii) any actual or proposed use by the Borrower of the proceeds of the Loans;
(iv) an Agent's or any Lender's entering into this Agreement; (v) the fact that
the Agent and the Banks have established the credit facilities evidenced hereby
in favor of the Borrower; (vi) the fact that the Agents and the Banks are
creditors of the Borrower and have or are alleged to have information regarding
the financial condition, strategic plans or business operations of the Borrower
and its Subsidiaries; (vii) the fact that the Agent and the Banks are material
creditors of the Borrower and are alleged to influence directly or indirectly
the business decisions or affairs of the Borrower and its Subsidiaries or their
financial condition; (viii) the exercise of any right or remedy the Agent or the
Banks may have under this Agreement or the other Loan Documents; (ix) any
violation or non-compliance by the Borrower or any Subsidiary of any applicable
law (including any Environmental Law) including, but not limited to, any
Indemnity Proceeding commenced by (A) the Internal Revenue Service or state
taxing authority or (B) any governmental authority or other Person under any
Environmental Law, including any Indemnity Proceeding commenced by a
governmental authority or other Person seeking remedial or other action to cause
the Borrower or its Subsidiaries (or its respective properties) (or the Agent or
the Banks as successors to the Borrower) to be in compliance with such
Environmental Laws; or (x) an Indemnified Party's reliance on telephonic or oral
requests, as described in Section 2.1(c); provided, however, that the Borrower
shall not be obligated to indemnify any Indemnified Party for any acts or
omissions of such Indemnified Party in connection with matters described in this
Section 12.7(a) that constitute gross negligence or willful misconduct.

            (b)   The Borrower's indemnification obligations under this
Section shall apply to all Indemnity Proceedings arising out of, or related
to, the foregoing whether or not an Indemnified Party is a named party in
such Indemnity Proceeding.  In this connection, this indemnification shall
cover all costs and expenses of any Indemnified Party in connection with any
deposition of any Indemnified Party or compliance with any subpoena
(including any subpoena requesting the production of documents).  This
indemnification shall, among other things, apply to any Indemnity Proceeding
commenced by other creditors of the Borrower or any Subsidiary, any
shareholder of the Borrower or any Subsidiary (whether such shareholder(s)
are prosecuting such Indemnity Proceeding in their individual capacity or
derivatively on behalf of the Borrower), any account debtor of the Borrower
or any Subsidiary or by any governmental authority.  This indemnification
shall apply to any Indemnity Proceeding arising during the pendency of any
bankruptcy proceeding filed by or against the Borrower or any Subsidiary.

            (c)   An Indemnified Party may conduct its own investigation and
defense of, and may formulate its own strategy with respect to, any
Indemnified Proceeding covered by this Section and, as provided above, all
costs and expenses incurred by the Indemnified Party shall be reimbursed by
the Borrower.  No action taken by legal counsel chosen by an Indemnified
Party in investigating or defending against any such Indemnified Proceeding
shall vitiate or in any way 



                                     -70-
<PAGE>   74

impair the obligations and duties of the Borrower hereunder to indemnify and
hold harmless each such Indemnified Party, provided, however, that (i) if the
Borrower is required to indemnify an Indemnified Party pursuant hereto and (ii)
the Borrower has provided evidence reasonably satisfactory to such Indemnified
Party that the Borrower has the financial wherewithal to reimburse such
Indemnified Party for any amount paid by such Indemnified Party with respect to
such Indemnified Proceeding, such Indemnified Party shall not settle or
compromise any such Indemnified Proceeding without the prior written consent of
the Borrower (which consent shall not be unreasonably withheld or delayed).

            (d)   If and to the extent that the obligations of the Borrower
hereunder are unenforceable for any reason, the Borrower hereby agrees to
make the maximum contribution to the payment and satisfaction of such
obligations which is permissible under applicable law.  The Borrower's
obligations hereunder shall survive any termination of this Agreement and the
other Loan Documents and the payment in full of the Obligations, and are in
addition to, and not in substitution of, any other of their obligations set
forth in this Agreement or any other Loan Document to which it is a party.

     SECTION 12.8. Termination; Survival.  At such time as (a) all of
the Advance Commitments have been terminated, (b) none of the Banks is
obligated any longer under this Agreement to make any Loans and (c) all
Obligations (other than obligations which survive as provided in the
following sentence) have been paid and satisfied in full, this Agreement
shall terminate.  Notwithstanding any termination of this Agreement, or of
the other Loan Documents, the indemnities to which the Agent and the Banks
are entitled under the provisions of this Agreement and the other Loan
Documents, and the waivers of jury trial and submission to jurisdiction
contained in Sections 12.12 and 12.17, shall continue in full force and
effect and shall protect the Agent and the Bank against events arising after
such termination as well as before.

     SECTION 12.9. Limitation of Liability.  The Borrower hereby
waives, releases, and agrees not to sue the Agent or any Bank or any of the
Agent's or any Bank's affiliates, officers, directors, employees, attorneys,
or agents for punitive damages in respect of any claim in connection with,
arising out of, or in any way related to, this Agreement or any of the other
Loan Documents, or any of the transactions contemplated by this Agreement or
financed hereby.

     SECTION 12.10. Construction.  The Agent, the Borrower and each
Bank acknowledge that each of them has had the benefit of legal counsel of
its own choice and has been afforded an opportunity to review this Agreement
and the other Loan Documents with its legal counsel and that this Agreement
and the other Loan Documents shall be construed as if jointly drafted by the
Agent, the Borrower and each Bank.

     SECTION 12.11. Right of Set-off.  Upon (a) the failure of the
Borrower to make any payment owed to the Banks when due (after any applicable
cure period) under any Loan Document or (b) the occurrence and during the
continuance of any Event of Default and the making of the request or the
granting of the consent specified by Section 10.1 to authorize the 



                                     -71-
<PAGE>   75

Agent to declare the Obligations due and payable pursuant to the provisions of
Section 10.1, each Bank and each Participant is hereby authorized at any time
and from time to time, to the fullest extent permitted by law, to set off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held and other indebtedness at any time owing by such Bank or
Participant to or for the credit or the account of the Borrower against any and
all of the obligations of the Borrower now or hereafter existing under any Loan
Document, whether or not such Bank or Participant shall have made any demand
under this Agreement or any such Loan Document and although such obligations may
be unmatured. Each Bank and Participant agrees promptly to notify the Borrower
after any such set-off and application made by such Bank, provided that the
failure to give such notice shall not affect the validity of such set-off and
application. The rights of each Bank and Participant under this Section are in
addition to other rights and remedies (including, without limitation, other
rights of set-off) that such Bank or Participant may have.

     SECTION 12.12. Waiver.  THE BORROWER EXPRESSLY WAIVES ITS RIGHT TO A TRIAL
BY JURY WITH RESPECT TO ANY LITIGATION OR OTHER DISPUTE RELATING TO THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT.

     SECTION 12.13. Severability.  If any provision of any Loan Document is
held to be illegal, invalid or unenforceable under present or future laws
during the term of this Agreement, such provision shall be fully severable,
such Loan Document shall be construed and enforced as if such illegal, invalid
or unenforceable provision had never comprised a part of such Loan Document,
and the remaining provisions of such Loan Document shall remain in full force
and effect and shall not be affected by the illegal, invalid or unenforceable
provision or by its severance from such Loan Document.

     SECTION 12.14. Entire Agreement.  Except for the other Loan Documents
expressly referred to herein, this Agreement represents the entire agreement
between the Banks, the Agent and the Borrower, supersedes all prior commitments
and may be modified only by an agreement in writing.

     SECTION 12.15. Binding Effect.  This Agreement shall be binding upon and
inure to the benefit of the Borrower, the Agent and each Bank and their
respective successors and assigns, except that no party shall have the right to
assign its rights hereunder or any interest herein without the prior written
consent of the other parties.

     SECTION 12.16. Governing Law.  This Agreement, the Notes and each Loan
Document shall be governed by, and construed in accordance with, the laws of
the Commonwealth of Virginia, without reference to conflict of laws principles.

     SECTION 12.17. Consent to Jurisdiction.  Each party to this Agreement
hereby irrevocably submits generally and unconditionally for itself and in
respect of its property to the jurisdiction of the Circuit Court for Fairfax
County, Virginia, or the United States District Court for the Eastern District
of Virginia, Alexandria Division, over any suit, action or proceeding



                                     -72-
<PAGE>   76

arising out of or relating to this Agreement, any Loan Document or the
Obligations. Each party to this Agreement hereby irrevocably waives, to the
fullest extent permitted by law, any objection that it may now or hereafter have
to the laying of venue in any such court and any claim that any such court is an
inconvenient forum. The Borrower hereby agrees and consents that, in addition to
any methods of service of process provided for under applicable law, all service
of process in any such suit, action or proceeding in the courts designated above
may be made by certified or registered mail, return receipt requested, directed
to the Borrower at its address for notice stated in Section 12.2 above, or at a
subsequent address of which the Agent received actual notice from the Borrower
in accordance with the terms hereof, and service so made shall be complete five
days after the same shall have been so mailed. The foregoing provisions shall
not limit the right of any Bank, the Agent or any other party hereto to serve
process in any other manner permitted by law or limit the right of any Bank or
the Agent or other party hereto to bring any suit, action or proceeding or to
obtain execution on any judgment rendered in any suit, action or proceeding in
any other appropriate jurisdiction or in any other manner.

     SECTION 12.18. Execution in Counterparts.  This Agreement may be executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.

     SECTION 12.19. Assignments.

            (a)   The provisions of this Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors
and assigns, except that the Borrower may neither assign nor otherwise
transfer any of its rights under this Agreement without the prior written
consent of the Banks.

            (b)   Any Bank may make, carry or transfer Loans or Letters of
Credit at, to or for the account of, any of its branch offices or the office
of an affiliate of such Bank except to the extent such transfer would result
in increased costs to the Borrower.

            (c)   Any Bank may at any time grant to one or more banks or
other financial institutions (each such bank or financial institution, a
"Participant") participating interests in the Advance Commitment, the Oasis
Acquisition Note, or the Obligations owing to such Bank; provided however,
(1) any such participating interest must be for a constant and not a varying
percentage interest, (2) no Bank may grant a participating interest in the
Advance Commitment, or if any part of the Advance Commitment has been
terminated, the aggregate outstanding principal balance of Revolving Notes
held by it, in an amount less than $5,000,000, and (3) after giving effect to
any such participation by a Bank, the amount of the Advance Commitment, or if
any of the Advance Commitment has been terminated, the aggregate outstanding
principal balance of Revolving Notes held by it, in which it has not granted
any participating interests must be at least $5,000,000.  No Participant
shall have any rights or benefits under this Agreement or any other Loan
Document, except (i) as provided in Section 12.11, and (ii) a 



                                       -73-
<PAGE>   77

Participant shall be entitled to the benefits of the cost protection provisions
contained in Article 3 to the same extent as if it were a Bank but not in excess
of the cost protections to which the Bank from which it purchased its
participation would be entitled. In the event of any such grant by a Bank of a
participating interest to a Participant, such Bank shall remain responsible for
the performance of its obligations hereunder, and the Borrower and the Agent
shall continue to deal solely and directly with such Bank in connection with
such Bank's rights and obligations under this Agreement. Any agreement pursuant
to which any Bank may grant such a participating interest shall provide that
such Bank shall retain the sole right and responsibility to enforce the
obligations of the Borrower hereunder including, without limitation, the right
to approve any amendment, modification or waiver of any provision of this
Agreement; provided, however, such Bank may agree with the Participant that it
will not, without the consent of the Participant, agree to (A) increase, or
extend the term or extend the time or waive any requirement for the reduction or
termination of, the Advance Commitment, (B) extend the date fixed for the
payment of principal of or interest on the Loans or Letter of Credit Obligations
or portions thereof owing to such Bank, (C) reduce the amount of any such
payment of principal, or (D) reduce the rate at which interest is payable
thereon. An assignment or other transfer which is not permitted by subsection
(d) or (e) below shall be given effect for purposes of this Agreement only to
the extent of a participating interest granted in accordance with this
subsection (c). The selling Bank shall notify the Agent and the Borrower of the
sale of any participation hereunder and the terms thereof.

            (d)   Any Bank may with the prior written consent of the Agent
and, so long as no Default or Event of Default shall have occurred and be
continuing, the Borrower (which consent, in the case of the Agent and the
Borrower, shall not be unreasonably withheld) assign to one or more Eligible
Assignees (each an "Assignee") all or a portion of the Advance Commitment and
its other rights and obligations under this Agreement and the Revolving
Notes; provided, however, (1) no such consent by the Borrower or the Agent
shall be required in the case of any assignment to another Bank or any
affiliate of such Bank or another Bank; (2) any partial assignment shall be
in an amount at least equal to $5,000,000 and after giving effect to such
assignment the assigning Bank retains part of the Advance Commitment, or if
the Advance Commitment has been terminated, holds Revolving Notes having an
aggregate outstanding principal balance, of at least $5,000,000; and (3) each
such assignment shall be effected by means of an Assignment and Acceptance
Agreement.  Upon execution and delivery of such instrument and payment by
such Assignee to such transferor Bank of an amount equal to the purchase
price agreed between such transferor Bank and such Assignee, such Assignee
shall be deemed to be a Bank party to this Agreement as of the effective date
of the Assignment and Acceptance Agreement and shall have all the rights and
obligations of a Bank with the Advance Commitment as set forth in such
Assignment and Acceptance Agreement, and the transferor Bank shall be
released from its obligations hereunder to a corresponding extent, and no
further consent or action by any party shall be required.  Upon the
consummation of any assignment pursuant to this subsection (d), the
transferor Bank, the Agent and the Borrower shall make appropriate
arrangements so that new Revolving Notes are issued to the Assignee and such
transferor Bank, as appropriate.  In connection with any such assignment, the
transferor Bank 



                                     -74-
<PAGE>   78

shall pay to the Agent an administrative fee for processing such assignment in
the amount of $2,500; provided, however, such fee shall not be payable in
connection with the first assignment of all or any portion of the Advance
Commitment of any Bank initially a party to this Agreement to an affiliate of
such Bank.

            (e)   The Agent shall maintain at its office specified in
Section 12.2 a copy of each Assignment and Acceptance Agreement delivered to
and accepted by it and a register for the recordation of the names and
addresses of the Banks and the Advance Commitment of each Bank from time to
time (the "Register").  The Agent shall give each Bank and the Borrower
notice of the assignment by any Bank of its rights as contemplated by this
Section.  The Borrower, the Agent and the Banks may treat each Person whose
name is recorded in the Register as a Bank hereunder for all purposes of this
Agreement.  The Register and copies of each Assignment and Acceptance
Agreement shall be available for inspection by the Borrower or any Bank at
any reasonable time and from time to time upon reasonable prior notice to the
Agent.  Upon its receipt of an Assignment and Acceptance Agreement executed
by an assigning Bank, together with each Revolving Note subject to such
assignment (the "Surrendered Note"), the Agent shall, if such Assignment and
Acceptance Agreement has been completed and if the Agent receives the
processing and recording fee described in subsection (d) above, (1) accept
such Assignment and Acceptance Agreement, (2) record the information
contained therein in the Register, and (3) give prompt notice thereof to the
Borrower.

            (f)   In addition to the assignments and participations permitted
under the foregoing provisions of this Section, any Bank may assign and
pledge all or any portion of its Loans and its Notes to any Federal Reserve
Bank as collateral security pursuant to Regulation A and any Operating
Circular issued by such Federal Reserve Bank, and such Loans and Notes shall
be fully transferable as provided therein.  No such assignment shall release
the assigning Bank from its obligations hereunder.

            (g)   Anything in this Section to the contrary notwithstanding,
no Bank may assign or participate any interest in any Loan held by it
hereunder to the Borrower or any Subsidiary or Affiliate of the Borrower.

            (h)   Each Bank agrees that, without the prior written consent of
the Borrower and the Agent, it will not make any assignment hereunder in any
manner or under any circumstances that would require registration or
qualification of, or filings in respect of, any Loan or Note under the
Securities Act or any other securities laws United States of America or of
any other jurisdiction.

     SECTION 12.20. Confidential Information.  The Agent and the Banks
agree to keep confidential (and to cause their respective affiliates,
officers, directors, employees, agents and representatives to keep
confidential) all information, materials and documents furnished to the Agent
or any such Bank by or on behalf of the Borrower (whether before or after the
Closing Date) which relates to the Borrower or any of its Subsidiaries (the
"Information").  Notwithstanding the foregoing, the Agent and each Bank shall
be permitted to disclose 



                                     -75-
<PAGE>   79

Information (a) to its affiliates, officers, directors, employees, agents and
representatives in connection with its participation in any of the transactions
evidenced by this Agreement or any other Loan Documents or other administration
of this Agreement or any other Loan Documents; (b) to the extent required by
applicable laws and regulations or by any subpoena or similar legal process, or
requested by any governmental authority; (c) to the extent such Information (1)
becomes publicly available other than as a result of a breach of this Agreement
or any agreement entered into pursuant to clause (d) below, (2) becomes
available to the Agent or such Bank on a non-confidential basis from a source
other than the Borrower or any of its Subsidiaries or (3) was available to the
Agent or such Bank on a non-confidential basis prior to its disclosure to the
Agent or such Bank by the Borrower; (d) to any Assignee or Participant (or
prospective Assignee or Participant) so long as such Assignee or Participant (or
prospective Assignee or Participant) first specifically agrees in a writing
furnished to and for the benefit of the Borrower to be bound by the terms of
this Section 12.20; or (e) to the extent that the Borrower shall have consented
in writing to such disclosure.
