"Options"). Pursuant to the terms and conditions of an Option Exchange and
Release Agreement to be entered into on or prior to the Closing Date by and
between the Company and each holder of Options (each, an "Exchange and
Release Agreement"), each such holder shall surrender the Options to the
Company in exchange for a cash payment equal to the amount indicated next to

                      ------------

have been satisfied or waived during such time period, or if that is not the
case, then the Closing shall occur on such other date on or before June 30,

if the Closing Date is between May 2, 2003 and May 12, 2003, the Parties

          (c) pay the aggregate amount of the Cash Out Payments to the Company

Bonus Obligations to the Company in accordance with Section 2(d).

     2.6. CLOSING FINANCIAL STATEMENTS.

          (a) As promptly as practicable following the Closing Date, but in no
event later than seventy-five (75) days after the Closing Date, Buyer shall
cause to be prepared, at Buyer's expense and in good faith, and submit to
Sellers an audited balance sheet of the Company as of the Closing Date (the
"Closing Balance Sheet") and the related audited statement of income for the
period then ended (collectively, the "Closing Financial Statements"). The
Closing Financial Statements shall be prepared by McGladrey & Pullen, LLP
(the "Accountant") in accordance with generally accepted accounting
principles consistent in all respects (including, without limitation,
classification and presentation of line items) with past practices, so long
as such practices have been in accordance with generally accepted accounting
principles (the "Accounting Principles"), provided, that the Closing
Financial Statements shall not include or reflect any impact from the (i)
cash-out of the Options pursuant to the Exchange and Release Agreements and
the funding and payment of the Employee Bonus Obligations, (ii) Excluded
Assets, (iii) Excluded Liabilities, (iv) any impact that might otherwise
result from the transactions contemplated herein, including but not limited
to, the Section 338(h)(10) Election, and (v) any related income tax effect
as a result of any of the foregoing, and provided further, that the Closing
Financial Statements shall include any fees and expenses incurred and paid
by the Company in connection with negotiation, preparation and execution of
this Agreement and the consummation of the transactions contemplated by this
Agreement, to the extent such fees and expenses would not otherwise be
reflected in the Closing Financial Statements under the Accounting
Principles.

     (b) In the event Sellers dispute the Closing Financial Statements as
delivered by Buyer, Sellers shall provide written notice (a "Notice of
Dispute") specifying in reasonable detail all points of disagreement with
the Closing Financial Statements to Buyer within thirty (30) days after
receipt of the Closing Financial Statements. If Sellers fail to deliver a
Notice of Dispute within such 30-day period, then the Closing Financial
Statements as delivered by Buyer shall be used for purposes of Section 2.7.
If Sellers deliver a Notice of Dispute within such 30-day period, Buyer and
Sellers shall endeavor in good faith to resolve all specified points of
disagreement within thirty (30) days after Seller's receipt of Buyer's
Notice of Dispute. If the dispute is not resolved within such 30-day period,
either or both Parties may


                                    -6-




refer the dispute to a partner in a nationally recognized "Big Four" firm of
independent public accountants (which firm shall not then have, nor within
the past three (3) years have had, any relationship with Buyer or its
Affiliates or the Sellers or their Affiliates) as shall be mutually
acceptable to Buyer and the Sellers, (the "Arbiter"), as arbitrator to
finally determine, as soon as practicable, all points of disagreement with
respect to the Closing Financial Statements. For purposes of such
arbitration, each Party shall submit proposed Closing Financial Statements
to the Arbiter and to the other Party, accompanied by such additional
information explaining such Party's position with respect to the Closing
Financial Statements as it (they) desires to submit. Each Party shall, at
the time of such submission, be free to revise positions they have
maintained in prior drafts of the Closing Financial Statements and related
discussions, but the Parties shall not be permitted to further modify their
proposed Closing Financial Statements once these are submitted to the
Arbiter. Buyer shall submit any revised Closing Financial Statements no
later than five (5) days after such referral. Sellers shall have ten (10)
days after such referral to submit their revised Closing Financial
Statements in response. The Arbiter shall apply the terms of this Section
2.6, and shall otherwise conduct the arbitration under such procedures as
the Parties may agree or, failing such agreement, under the Commercial
Arbitration Rules of the American Arbitration Association. The fees and
expenses of the arbitration and the Arbiter incurred in connection with the
arbitration of the Closing Financial Statements shall be allocated between
the Parties by the Arbiter in proportion to the extent either Party did not
prevail on the points of disagreement in the Closing Financial Statements;
provided, that such fees and expenses shall not include, so long as a Party
complies with the procedures of this Section 2.6, the other Party's outside
counsel or accounting fees. All determinations by the Arbiter shall be
final, conclusive and binding with respect to the Closing Financial
Statements and the allocation of arbitration fees and expenses.

          (c) Buyer agrees to cooperate with Sellers in attempting to resolve
any points of disagreement referred to in Section 2.6(b), including without
limitation, making reasonably available to Sellers to the extent reasonably
requested all books, records, work papers and personnel; provided, however,
that Sellers will conduct their work in a manner that does not unreasonably
interfere with or disrupt the conduct of the Business by the Company after
the Closing.

     2.7. ADJUSTMENT TO PURCHASE PRICE

          (a) The Purchase Price shall be subject to downward adjustment in the
event (i) the stockholders' equity shown on the Closing Balance Sheet as
finally determined (by agreement or otherwise) in accordance with Section
2.6 ("Final Adjusted Stockholders' Equity"), is less than Six Million Six
Hundred Eighty-Eight Thousand Four Hundred Sixty Seven Dollars ($6,688,467),
or (ii) the aggregate amount of the Bank Obligations on the Closing Date
exceeds Seventeen Million Eight Hundred Thirty Thousand Dollars
($17,830,000). In the event the Purchase Price would be subject to
adjustment based on both of the foregoing occurring, the adjustment that
generates the greater purchase price reduction will be used. Sellers shall
pay to Buyer, in the manner provided in Section 2.7(b), the amount of any
Purchase Price adjustment, on a dollar for dollar basis, that may be owing
to Buyer under this Section 2.7(a).

                                    -7-




          (b) If a payment pursuant to Section 2.7(a) is due from Sellers to
Buyer, it shall be made within five (5) business days after the amount of
the adjustment has been finally determined.

     2.8. SECTION 338(h)(10) ELECTION.

          (a) As provided in Section 7.9 below, Buyer and Seller shall jointly
make the Section 338 Election (as that term is hereinafter defined in
Section 7.9(a))and Buyer shall pay to each of the Sellers such amount as is
required to cause such Seller to be in the same after-Tax position with
respect to the sale of his/her Shares in which he/she would have been if the
Section 338 Election not been made (the "Section 338 Price Increase") (other
than the Tax costs to Sellers of the Taxes referred to in Section 2.9). The
Parties agree that any payment among the Parties in respect of the amount of
the Section 338 Price Increase shall be deemed to be an adjustment in the
amount of the Purchase Price, except to the extent required to be treated as
interest under the Code or other relevant Tax law).

          (b) The Section 338 Price Increase shall be determined and be paid
under the procedures provided in Section 7.9.

          (c) The Section 338 Price Increase shall take into account, without
limitation, the following factors:

              (i)   All Taxes imposed on such Seller (other than Taxes referred
to in Section 2.9 hereof) as a result of the making of the Section 338
Election, whether imposed directly or indirectly through withholding or
other means (including Taxes on the increases to the Purchase Price required
under this Section 2.8 and Section 7.9), to the extent such Taxes exceed the
amount of such Taxes that would have been imposed on the Seller if the
Section 338 Election had not been made with respect to the acquisition of
the Shares hereunder; and

              (ii)  The amount necessary to cover the Taxes that the Sellers
may be required to pay because of the payment to them of the Section 338
Price Increase.

          (d) The Section 338 Price Increase shall be computed using the
following assumptions:

              (i)   But for the Section 338 Election, each Seller would have
recognized long-term capital gain and no ordinary income on the sale of the
Shares (except to the extent that payments would have been required to be
characterized as interest);

              (ii)  Each Seller has no other installment receivables arising
in the year of the Closing which are being reported on the installment
method pursuant to Section 453 of the Code;

              (iii) Each Seller would incur Income Tax liability at the highest
marginal federal, state and local Income Tax rate applicable to ordinary
income or long-term capital gains, as the case may be (determined in the
case of gain from the sale of the Shares by reference to the residence of
each Seller and, in the case of income of the Company reportable


                                    -8-




as income by such Seller in taxing jurisdictions other than his state of
residence, at the maximum marginal rate applicable in each state and local
taxing jurisdiction to which such income is allocable or apportionable).

     2.9. BUILT-IN GAINS TAXES. As soon as reasonably practicable after the
Closing, the Parties will mutually agree upon the determination of the
valuation of the assets of the Company required to determine the Built-in
Gains Taxes owed by the Company, if any, as a result of the Section 338
Election; provided that if such valuations are not mutually agreed upon
within thirty (30) days prior to the earliest date that a Tax Return
covering the Built-in Gains Taxes is due, then the valuations shall be
determined by the Accountant. The Sellers, pro rata (based on their
ownership of the Shares immediately prior to the Closing) shall be liable
for and pay to the Company as hereinafter provided, the amount of the
Built-in Gains Taxes owing by the Company to the relevant taxing
authorities. If there are amounts owing from the Company to the relevant
taxing authorities for Built-in Gains Taxes, the Company shall pay the full
amount of the Built-in Gains Taxes and the Sellers shall, within five (5)
business days after receipt of notice from the Company, pay to the Company,
their respective pro rata shares (based on their ownership of the Shares
immediately prior to the Closing) of such Built-in Gains Taxes that have
been paid. Furthermore, the Sellers shall pay their respective pro rata
shares on behalf of and shall indemnify the Company pro rata (based on their
ownership of the Shares immediately prior to the Closing) against any
additional Built-in Gains Taxes, including related interest and penalties,
assessed against the Company as a result of a final determination by any
taxing authority (following an audit or review). For purposes hereof, the
term "Built-in Gains Taxes" shall mean Taxes imposed pursuant to Section
1374 of the Code, and similar Taxes under state or local Income Tax laws
with respect to net unrealized built in gains existing in the assets of the
Company as of the effective date of its election to be taxed under
Subchapter S of the Code, or similar state and local Income Tax laws.

     2.10. EXCLUDED ASSETS; EXCLUDED LIABILITIES.

          (a) Prior to the Closing, the Sellers shall cause the Company to
assign and transfer to the Sellers the following (the "Excluded Assets"):

"Excluded Liabilities")

any costs and expenses related to protesting such claim;

              (vi)   All liabilities and obligations of the Company owing to

the laws of the State of Maryland. The Company is duly qualified as a
foreign corporation to do business and is in good standing as a foreign

since December 31, 2002, there has not been any change in the financial
condition or results of operations of the Company from that shown on the

          (c) The Company has provided Buyer with projections for the expected
financial results of the Company through its 2006 fiscal year which are
attached as Schedule 3.4(c) (the "Company Projections"). Subject to the

Company or the Business or otherwise relating to Buyer's rights and
obligations hereunder or any other obligations of the Company.

any of their proprietary, confidential or classified information (except to
the extent required for purposes of defending or prosecuting any third party
legal proceedings).

reasonable commercial efforts to advise and assist in obtaining these
NID(s).

     7.5. PUBLIC ANNOUNCEMENTS; CONFIDENTIALITY.

          (a) No Party to this Agreement shall issue any press release or make

contemplated hereby without the prior written consent of the other Parties,
except as required by Law or by the rules and regulations of any national
securities exchange on which the securities of Buyer or its Affiliates are
listed; provided that, if a disclosure is determined by Buyer to be required
by law or by the rules and regulations of any national securities exchange
on which Buyer's or Affiliates securities listed, Buyer shall notify the
other Parties hereto as soon as possible in advance of such disclosure and,
to the extent practicable, give the other Parties a reasonable opportunity
to review and comment on such disclosure.

          (b) The Parties' obligations under the Mutual Non-Disclosure Agreement
dated November 5, 2002 (the "Confidentiality Agreement") remain in full

relating to the Business transferred hereunder.

          (c) After the Closing, (i) Sellers shall keep confidential, and cause
their Affiliates and instruct their agents, representatives, consultants and

of a breach of this Section.

          (d) If any Party shall determine that it may be required by Law or
administrative process to make a disclosure otherwise prohibited by this
Section, it shall promptly so advise each other Party and shall cooperate
with such other Parties and take such actions as shall be reasonably
requested by such other Parties in order to prevent or limit such required
disclosure.

     7.6. FURTHER ASSURANCES. The Parties shall cooperate and shall use
their reasonable best efforts to take, or to cause to be taken, and to do,
or cause to be done, all things necessary, proper and advisable to
consummate and make effective, in the most expeditious manner practicable,
the transactions contemplated hereby, including, without limitation, using
their reasonable best efforts to satisfy, or to cause to be satisfied, all
of the conditions set forth in Articles V and VI hereof. From and after the
Closing, the Parties shall do such acts and execute such documents and
instruments as may be reasonably requested by the other Parties to make
effective the transactions contemplated hereby. In the event that consents,
approvals or other


                                    -37-




authorizations or other acts contemplated by this Agreement have not been
fully effected as of Closing, the Parties will continue after the Closing,
without further consideration, to use their reasonable best efforts to carry
out such transactions; provided, however, in the event that certain
approvals, consents or other necessary documentation cannot be secured, then
the Party having legal responsibility, ownership or other control shall act
on behalf of the other Parties, without further consideration, to effect the
essential intention of the Parties with respect to the transactions
contemplated by this Agreement.

     7.7. KNOWLEDGE OF BREACH; CURRENT INFORMATION. Each Party shall advise
the other Parties in writing promptly (and in any event prior to the
Closing) of (i) the occurrence of any event which renders any of such
Party's representations or warranties set forth herein inaccurate in any
material respect or the awareness of such Party that any representation or
warranty set forth herein was not accurate in all material respects when
made; and (ii) the failure of such Party to comply with or accomplish any of
the covenants or agreements set forth herein in any material respect.
Between the date hereof and the Closing, Sellers will also cause the Company
to provide Buyer promptly on becoming available copies of all operating
reports and financial statements prepared by or for the Company. If any of
the information disclosed on any of the Schedules of a Party hereto is (or
becomes) incorrect, such Party shall prepare and deliver to the other
Parties updated Schedules promptly after discovering same and prior to the
Closing. If any matter arises after the date hereof which, had such matter
existed or occurred on or prior to the date hereof, would have been required
to have been disclosed on a Party's schedules, such Party shall prepare and
deliver to the other Parties supplemental schedules prior to the Closing.
Any supplemental schedules delivered pursuant to Section 7.7 shall be deemed
to amend the delivering Party's Schedules, but shall not be effective for
the purposes of Sections 5.1 or 6.1 hereof.

     7.8. TAX MATTERS.

          (a) Buyer will prepare and file, or caused to be prepared and filed,
all Tax Returns for the Company that are due after the Closing Date, that
include periods that end on or before or include the Closing Date, in a
manner that is consistent with prior returns. Buyer shall have such tax
returns prepared by Bormel, Grice & Associates or such other accountant or
accounting firm as the Parties may otherwise agree in writing. Except for
the Section 338 Election, no elections will be made that were not made in
prior returns, and no elections made in prior Tax Returns will be changed
without the prior written consent of the Sellers. Buyer shall provide
Sellers with copies of any such completed Tax Return at least forty-five
(45) days prior to the due date for filing (inclusive of any extensions) of
such Tax Return, for Sellers review and approval. Sellers shall be deemed to
have accepted the Tax Return unless Sellers deliver to the Buyers a written
notice of disagreement within 10 days of receipt of the Tax Return. If
Sellers deliver such notice of disagreement, Sellers and Buyer will
negotiate in good faith to resolve the items of disagreement. If Buyer and
Seller do not reach agreement within ten (10) days of Buyer's receipt of
Sellers' notice of disagreement, the procedures set forth in Section 7.9(e)
shall apply. Sellers will be responsible for reporting and paying the Income
Taxes due for any income passed through to them for any taxable period of
the Company that ends on or before the effective time of the Closing (the
"Pre-Closing Tax Period") by reason of the Company's S Corporation status
prior to the Closing; provided, however, that if the Closing Date occurs on
any date between May 2, 2003 and May 12, 2003, inclusive, Buyer shall
indemnify the Sellers


                                    -38-




for any Income Taxes reported and paid by Sellers pursuant to this sentence
relating to any profit attributable to the period May 1, 2003 through the
Closing Date.

          (b) With respect to any taxable period that would otherwise include
but not end on the Closing Date, to the extent permissible pursuant to
applicable law, Sellers will, and Buyer will cause the Company to, take all
steps as are or may be reasonably necessary, including, without limitation,
the filing of elections or returns with applicable taxing authorities, to
cause such period to end on the Closing Date. Buyer will prepare and file
all such Tax Returns. In any case where applicable law does not permit the
Company to close its taxable year on the Closing Date, then Taxes, if any,
attributable to the taxable period of the Company that includes the Closing
Date shall be allocated to Sellers for that portion of the taxable period up
to and including the Closing Date and to the Buyer for the portion of the
taxable period subsequent to the Closing Date. Sellers shall have access to
such information as Sellers may reasonably request (including access to
books, records and personnel) pursuant to Section 7.2(b) in order for the
operations of the Company to be properly reported in Tax Returns, for the
preparation for any Tax audit or for the prosecution or defense of any
claims, suit or proceeding relating to Taxes for any Pre-Closing Tax Period.

          (c) Sellers and Buyer shall cooperate as and to the extent reasonably
requested by any other Party hereto, in connection with the filing of Tax
Returns and any audit, litigation or other proceeding with respect to Taxes.
Such cooperation shall include the retention and (upon another party's
request) the provision of records and information which are reasonably
relevant to any such Tax Return, audit, litigation or other proceeding and
making employees available on a mutually convenient basis to provide
additional information and explanation of any material provided hereunder.
Sellers and Buyer agree (i) to retain all books and records with respect to
Tax matters pertinent to the Company relating to any taxable period
beginning before the Closing Date until the expiration of the statute of
limitations of the respective taxable periods, and (ii) to give any other
party reasonable written notice prior to transferring, destroying or
discarding any such books and records and, if the other party so requests,
Buyer or Sellers, as the case may be, shall allow the other party to take
possession of such books and records.

          (d) Buyer will, upon receipt of notice by any taxing authority of an
intention to audit the Company for any periods that end on or before or
include the Closing Date, notify the Sellers in writing within five (5)
business days of such notice. Subject to Buyer's obligations in Section
7.8(c), Sellers shall, at Sellers' expense, manage and control all aspects
of such audit and related proceedings, including judicial proceedings, and
shall keep Buyer reasonably informed as to the status of any such
proceedings. Buyer shall have the right, at its expense to participate in
such audit and related proceedings. In no event shall Buyer or the Company
make, accept, or enter into a settlement or other compromise , or forego or
terminate any proceeding relating to such Taxes for such periods without the
prior written consent of the Sellers, which shall not be unreasonably
withheld. To the extent this Section 7.8(d) conflicts with any other
provisions of this Agreement, this Section 7.8(d) shall control.

          (e) Buyer shall not, and shall not permit the Company to file any
amended Tax returns for any periods that end on or prior to or include the
Closing Date, without the prior written consent of the Sellers, which shall
not be unreasonably withheld if the amended


                                    -39-




return is to be filed to reflect the Section 338 Election, which is made in
compliance with the terms of Section 7.9 after the relevant Tax return for
the Company has been filed.

     7.9. SECTION 338(h)(10) ELECTION.

          (a) Subject to the Buyer's delivery of the Section 338 Price Increase,
pursuant to Section 2.8 and this Section 7.9, each of the Sellers shall join
with the Buyer in making an election under Section 338(h)(10) of the Code
(and any similar elections under state, local, or foreign tax law)
(collectively, a "Section 338 Election") with respect to the purchase and
sale of the Shares hereunder. For Tax purposes, to the extent permitted by
law, Buyer and Sellers will report the stock purchase as a purchase and
sale, respectively, of the assets of the Company, followed by the
liquidation of the Company, where such treatment is the required consequence
of the Section 338 Election. Each Seller shall include any income, gain,
loss, deduction or other tax items for the taxable period ending on the
Closing Date on the Seller's personal Tax Returns in a manner consistent
with such treatment, and in the amounts as determined pursuant to this
Section 7.9. The Buyer and Sellers shall, in good faith, use all reasonable
efforts to complete the Section 338 Forms and the delivery of the Section
338 Price Increase by December 31, 2003.

          (b) No later than 30 days after a final determination of the matters
described in Section 7.9(e), Buyer shall prepare and submit to Sellers the
forms that are required to be completed for the Section 338 Election (the
"Section 338 Forms") and are required to be filed to make such election.
With the submission of such Section 338 Forms, Buyer shall advise the
Sellers in writing of those actions that Buyer considers necessary and
appropriate for the Sellers to take to effect, preserve, or perfect a timely
Section 338 Election.

          (c) On or prior to the thirtieth (30th) day after Sellers' receipt of
any Section 338 Form from Buyer, each Seller shall deliver to Buyer either
(A) such executed Section 338 Form or (B) a written notice specifying in
reasonable detail all disputed items and the basis therefor. If Buyer and
Sellers have been unable to resolve all disputed matters relating to the
Section 338 Form within thirty (30) days after Buyer's receipt of the
written notice described in clause (B) above, any remaining disputed issues
shall be resolved pursuant to Section 7.9(h) below.

          (d) Except for the Sellers' responsibilities in this Section 7.9,
Buyer will have the sole responsibility for assuring that the Section 338
Election is validly and timely made. Each of the Sellers (to the extent so
advised by the Buyer pursuant to Section 7.9(b) and subject to Buyer's
compliance with the terms of Sections 7.9 and 2.8) and the Buyer shall
comply fully with all filing and other requirements necessary to effectuate
such Section 338 Election on a timely basis and agree to cooperate in good
faith with each other in the preparation and timely filing of any Tax
Returns required to be filed in connection with the making of such Section
338 Election.

          (e) The Sellers and the Buyer shall use their best efforts to
mutually agree upon the initial determination and allocation among the
assets of the Company of the "aggregate deemed sale price" and "adjusted
grossed up basis" (within the meaning of Treas. Regs. Sections 1.338-4 and
1.338-5 respectively,) no later than (i) thirty (30) days after the final

                                    -40-




determination (by agreement or otherwise) of the Closing Financial
Statements in accordance with Section 2.6 or (ii) one hundred twenty (120)
days after the Closing Date, whichever is earlier. Such allocation shall be
made in accordance with Section 338 of the Code and the regulations
thereunder. If Buyer and all of the Sellers are unable to agree upon such
determination or allocation within such time period, then such determination
and allocation shall be resolved pursuant to Section 7.9(h) below. When
finally determined hereunder (whether by agreement or otherwise) such
allocation shall be binding upon each of the Sellers and the Buyer for all
Tax purposes.

          (f) No later than thirty (30) days after a final determination of the
matters described in Section 7.9(e), Buyer shall (i) cause the Accountant to
prepare computations of the Section 338 Price Increase and (ii) deliver them
to Sellers. Such computations shall be binding on all of the Parties, unless
a notice of disputed items is delivered by Sellers to Buyer within 30 days
of the receipt of the computations from Buyer, or until and unless revised
by a later recomputation pursuant to Section 7.9(g). The initial computation
of the Section 338 Price Increase shall be provided to the Sellers prior to
or at the same time as the Section 338 Forms are provided to Sellers for
review. Buyer shall pay to each of the Sellers, pro rata (based on their
ownership of the Shares immediately prior to the Closing), the amount of the
initial computation of the Section 338 Price Increase on the date Buyer has
received executed Section 338 Forms from all of the Sellers in accordance
with the provisions of this Section 7.9, with such payments to be made by
wire transfer of immediately available funds pursuant to wiring instructions
furnished by the Sellers.

          (g) The Buyer promptly shall cause the Accountant to prepare a
recomputation of the Section 338 Price Increase upon Buyer receiving notice
that such a recomputation is necessary to reflect either a change to the
income recognized by reason of the Section 338 Election (including by reason
of a change in the Purchase Price), or a redetermination by a taxing
authority of the effect on the Sellers of the Section 338 Election that is
inconsistent with the most recent computations of the Section 338 Price
Increase. Subsequent payments between the Parties as a result of any
subsequent adjustments to the Section 338 Price Increase amount shall be
made within five (5) business days after the date that a revised computation
of the Section 338 Price Increase is determined by the Accountant and
provided to the Parties. The recomputation of the Section 338 Price Increase
shall be subject to the same review and approval process as described in
Section 7.9(f).

          (h) If there shall be a dispute between the Parties regarding any
matters concerning the Section 338 Election, a Tax Return prepared pursuant
to Section 7.8(a) or the payments contemplated by Section 2.8 and this
Section 7.9, and the dispute is not resolved within the time period
identified for such resolution in the relevant section, the dispute shall be
referred to the Arbiter. The Arbiter shall finally determine, as soon as
practicable, all points of disagreement with respect to the submitted
matter. Buyer shall submit any statement of its position to the Arbiter no
later than five (5) days after such referral. Sellers shall have ten (10)
days after such referral to submit their proposed revision of the position
urged by the Buyer. The Arbiter shall apply the terms of this Agreement, the
Code, regulations and other relevant law or tax authority announcements or
positions and shall determine, in its judgment, which position is more
likely to prevail. The Arbiter's fees and expenses shall be paid by the
party that did not prevail on the point of disagreement.

                                    -41-




     7.10. CERTAIN LIABILITIES. Prior to the Closing, the Company and the
Sellers shall take all action as is necessary to cause any notes, or
receivables due to the Company from the Sellers or the Company's officers or
directors to be cancelled or otherwise extinguished. Further, the Company
and the Sellers agree to use commercially reasonable efforts prior to the
Closing to do all such acts and undertakings as are necessary to cause title
to the Excluded Assets to be transferred to the Sellers and to cause the
Company to be released from any and all liabilities, obligations and Liens
related to the Excluded Liabilities.

     7.11. CERTAIN EMPLOYEE ISSUES.

           (a) Buyer agrees that during the period commencing on the Closing
Date and ending on the first anniversary thereof, the employees of the
Company will be provided with benefits under Plans that, in the aggregate,
are comparable with those with which they are currently being provided by
the Company.

           (b) Buyer will cause each of the Plans in which employees of the
Company are eligible to participate to take into account for purposes of
eligibility, vesting and for purposes of severance, vacation and sick leave
benefit accrual thereunder, the length of service of such employees with the
Company prior to the Closing Date, to the same extent that such service was
credited under a comparable plan of the Company; provided, however, that
such credit shall not result in a duplication of benefits for the same
period of service.

           (c) Buyer shall take all such actions as are necessary or
appropriate to ensure that each employee of the Company, each such
employee's spouse and dependent children covered under a group health plan
of the Company immediately prior to the Closing Date shall be eligible to
enroll for coverage effective as of the Closing Date under a group health
plan maintained by the Company. Buyer shall take all such reasonable actions
as are necessary or appropriate to cause each group health plan maintained
by the Company in which an employee of the Company, any such employee's
spouse or dependent children will participate on and after the Closing Date
to waive any waiting period, evidence of insurability requirement or
pre-existing condition limitation that did not also apply under the
applicable group health plan of the Company.

          (d) To the extent that an employee of the Company has satisfied in
whole or in part any annual deductible or paid any out-of-pocket or
co-payment expenses (as evidenced by reasonable documentation to be provided
to Purchaser) under a group health plan of the Company for the 2003 plan
year, such employees shall be credited therefore under the corresponding
provisions of the corresponding group health plan of the Company in which
such individual participates on and after the Closing Date.

          (e) Nothing contained in this Agreement shall create any third party
beneficiary rights in any employee of the Company, any beneficiary or
dependent thereof, with respect to the benefits that may be provided to such
employees by the Company or Buyer or under any Plan, or with respect to any
entitlement of an employee to employment or continued employment with the
Company for any specified period after the Closing Date.

                                    -42-




     7.12. EMPLOYEE BONUSES. Prior to the Closing, the Company may award
bonuses to key employees of the Company as determined by the Sellers
pursuant to which such employees shall be given bonuses in fixed amounts in
the aggregate totaling up to $875,000 (the "Employee Bonuses"). At or prior
to the Closing, Sellers will deliver (or cause the Company to deliver) to
Buyer a listing of the employees receiving the Employee Bonuses along with
the amount payable to each such employee. Such Employee Bonuses are being
paid out to such employees as recognition of their efforts on behalf of the
Company prior to the Closing Date.

     7.13. COLLECTION OF ACCOUNTS RECEIVABLE. With respect to all of the
contract receivables of the Company existing as of the Closing
(collectively, the "Accounts Receivable"), the Company shall use
commercially reasonable collection efforts in order to attempt to collect
all of such Accounts Receivable by August 31, 2003. If any of the Accounts
Receivable have not been collected by the Company by August 31, 2003 (the
"Uncollected Receivables"), then the Sellers shall be liable to Buyer for
the amount of any such Uncollected Receivables as hereinafter set forth. If
there is a Holdback Amount, then the aggregate amount of the Uncollected
Receivables shall be retained by Buyer and will reduce the Holdback Amount
on a dollar for dollar basis and the remaining balance of the Holdback
Amount shall be paid on September 10, 2003 to Sellers pro rata (based on
their ownership of their Shares immediately prior to the Closing) by wire
transfer of immediately available funds pursuant to wiring instructions
furnished by Sellers. In the event the aggregate amount of the Uncollected
Receivables exceeds the Holdback Amount, then Sellers shall indemnify Buyer
and the Company for any such excess amount in accordance with Article VIII
of this Agreement. If the Company receives payment on an Uncollected
Receivable after the amount has been retained from the Holdback or Sellers
have indemnified Buyer and the Company under Article VIII hereof, Buyer will
cause the Company to promptly remit to the Sellers pro rata (based on their
ownership of the Shares immediately prior to the Closing) any such payment
received.

     8.1.  INDEMNIFICATION BY SELLERS. Subject to the limitations and other
agreements of Section 8.2 below, from and after the Closing the Sellers,
severally in proportion to each Seller's ownership of the Shares immediately
prior to the Closing, shall indemnify and hold harmless the Buyer and the
Company and each of their respective Affiliates and the directors, officers,
employees, successors, permitted assigns and agents of each of them (the
"Buyer Indemnified Persons") against all liabilities, losses, damages, costs
and expenses reasonably incurred by them as a result of:

           (a) Any misrepresentation, breach of warranty or non-fulfillment of
any agreement or covenant on the part of the Company (other than covenants and
agreements to be performed by the Company after the Closing) or Sellers
under this Agreement, or any misrepresentation in any certificate or other
instrument furnished or to be furnished pursuant to this Agreement by the
Company (other than any certificate or other instrument to be furnished by
the Company after the Closing) or Sellers;

           (b) Any of the Excluded Liabilities;

                                    -43-

Schedule 3.32(b);
----------------

          (d) Any claim, action, suit or other proceeding brought by or on
behalf of any holder of the Options against the Company or the Buyer seeking
to void, nullify, overturn or terminate the Exchange Agreement and Release
entered into by such Option holder or seeking to contest, dispute or
increase the compensation payable to such Option holder under the Exchange
Agreement and Release (each, an "Option Holder Claim");

          (e) Any loss or damage (including an earnings charge) the Company may
incur or suffer (i) if the government exercises its purchase option of the
equipment it is currently leasing from the Company as described on
Schedule 3.30, (ii) if the Company, following the Closing, exercises its
-------------
purchase option of the equipment it is currently leasing under the Amplicon
Lease and the government does not exercise such purchase option and does not
enter into a new lease agreement with Company with respect to such equipment
for the period after July 31, 2003, (iii) if the government does not
exercise such purchase option and the Company terminates the Amplicon Lease
as provided in the Amplicon Lease, (iv) due to the failure of the Company to
provide Buyer on or before the date hereof complete and correct copies of
the Amplicon Lease, including any amendments, exhibits, schedules or
attachments thereto, or (v) due to the failure of the Company's lease with
the government and the Amplicon Lease to each expire on July 31, 2003. For
purposes hereof, the term "Amplicon Lease" means that certain Lease

including any attachments, schedules, exhibits, amendments or modifications
thereto;

          (f) The failure of the Company to collect all of its Accounts
Receivable existing as of the Closing prior to September 1, 2003, but only
to the extent the Uncollected Receivables are in excess of the Holdback
Amount; and

          (g) All actions, suits, proceedings, judgments, settlement payments,
costs and expenses (including reasonable attorneys' fees and expenses)
reasonably incurred by the Company or the Buyer incident to any of the
foregoing;

     provided, that any such amounts shall

              (i)  be computed considering the Tax benefit actually recognized
by the Buyer Indemnified Person arising from the indemnified matter, and

              (ii) not include or be recoverable by any Buyer Indemnified
Person to the extent covered by insurance available to the Buyer Indemnified
Person.

SELLERS. Notwithstanding the foregoing provisions of Section 8.1 and any
other provision of this Agreement:

          (a) The Sellers shall not have any requirement to make

foregoing, any claim that has been timely asserted by a Buyer Indemnified
Person in accordance with this Section 8.2(b) and Section 8.5 hereof shall
survive past the applicable time limits set forth in this Section 8.2(b)
until the final resolution of the claim.

limitation, pursuant to this Article VIII) with regard to any representation
made in Section 3.32 other than the representations made by such Seller with
respect to himself or herself only and with respect to the Company

          (e) Notwithstanding anything to the contrary set forth in this
Agreement, the Parties agree that for purposes of determining Buyer's
entitlement to indemnification from the Sellers hereunder, all
representations and warranties made in Article III

                                    -45-




of this Agreement shall be deemed to have been made without any "Material
Adverse Effect" qualifications and, therefore, the amount of any claim for
indemnification shall be determined without regard to whether or not there
was a "Material Adverse Effect" qualification included as part of the
representation or warranty.

     8.3. INDEMNIFICATION BY BUYER. Subject to the limitations of Section 8.4
below, from and after the Closing the Buyer shall indemnify and hold
harmless the Sellers and their respective heirs, legal representatives,
successors and assigns (the "Sellers Indemnified Persons") against all
liabilities, losses, damages, costs and expenses reasonably incurred by them
as a result of:

          (a) Any misrepresentation, breach of warranty or non-fulfillment of
any agreement or covenant on the part of the Buyer, or any non-fulfillment of
any agreement of the Company after the Closing, under this Agreement, or any
misrepresentation in any certificate or other instrument furnished or to be
furnished by the Buyer to the Sellers under this Agreement;

Person to the extent covered by insurance available to the Seller Indemnified
Person.

     8.4. LIMITATIONS ON LIABILITY OF BUYER. Notwithstanding the foregoing

payments under this Agreement until the aggregate amount of the
indemnification obligation of the Buyer thereunder shall exceed Six Hundred
Sixty-Five Thousand Dollars ($665,000) (the "Buyer's Minimum Threshold
Amount"), in which case the Buyer shall only be liable for the portion of
such obligation in excess of the "Buyer's Minimum Threshold Amount", except
as set forth in Section 8.4(d) below.

          (b) The Sellers shall not have any requirement to make indemnification
payments under this Agreement for breaches of representations or warranties
or for breaches of covenants and agreements to be performed prior to
Closing, except in respect of matters as to which the Sellers shall have

first anniversary of the Closing Date, provided that claims determined by

                                    -46-




final, non-appealable judgment of a court of competent jurisdiction to arise
from fraud by Buyer may be asserted at any time prior to the expiration of
the applicable statutes of limitations therefor. Notwithstanding the
foregoing, any claim that has been timely asserted by a Seller Indemnified
Person in accordance with this Section 8.4(b) and Section 8.5 hereof shall
survive past the applicable time limits set forth in this Section 8.4(b)
until the final resolution of the claim.

          (c) The aggregate liability of the Buyer under this Agreement shall
not exceed Two Million Five Hundred Thousand Dollars ($2,500,000) except as set
forth in Section 8.4(d) below.

          (d) Notwithstanding anything to the contrary set forth herein, the
Buyer's Minimum Threshold Amount set forth in Section 8.4(a) and the maximum
limitations on the Buyer's indemnification liability set forth in Section
8.4(c) shall not be applicable to any (i) obligations of the Buyer pursuant
to Section 9.7, (ii) claims determined by final, non-appealable judgment of
a court of competent jurisdiction to arise from fraud by Buyer, (iii) claims
arising from the failure of the Company or the Buyer to pay the amount of
the Section 338 Price Increase set forth under Sections 2.8 and 7.9, or (iv)
claims arising from the failure of the Buyer to pay to the Sellers the
Holdback Amount or any portion thereof that may be owing to the Sellers in
accordance with Section 7.13.

     8.5. NOTICE OF CLAIM. In the event that Buyer seeks indemnification on
behalf of a Buyer Indemnified Person, or Sellers seek indemnification on
behalf of a Seller Indemnified Person, such Party seeking indemnification
(the "Indemnified Party") shall give reasonably prompt written notice to the
Party from which it seeks indemnification (the "Indemnifying Party")
specifying the facts constituting the basis for such claim and the amount,
to the extent known, of the claim asserted. The Parties shall attempt for
not less than thirty (30) days after the giving of such notice to negotiate
a mutually satisfactory resolution of such matter. In the event the Parties
are not able to agree on a mutually satisfactory resolution, the Indemnified
Party or the Indemnifying Party may seek to resolve the dispute by
litigation in any court of competent jurisdiction.

     8.6. RIGHT TO CONTEST CLAIMS OF THIRD PERSONS. If an Indemnified Party
may be entitled to indemnification hereunder because of a claim asserted by
any claimant other than a Buyer Indemnified Person or a Seller Indemnified
Person hereunder (a "Third Person"), the Indemnified Party shall give the
Indemnifying Party reasonably prompt written notice thereof. The
Indemnifying Party shall have the right, upon written notice to the
Indemnified Party, and using counsel reasonably satisfactory to the
Indemnified Party, to investigate, contest, control the defense of or settle
the claim alleged by such Third Person (a "Third Person Claim"); the
Indemnified Party may thereafter participate in (but not control) the
defense of any such Third Person Claim with its own counsel at its own
expense. If the Indemnifying Party shall fail to assume the defense of any
such Third Person Claim,

          (a) the Indemnified Party, in good faith, may defend against such
claim, in such manner as it may deem appropriate, including, but not limited
to, settling such claim, after giving at least thirty (30) days' advance
notice of any proposed settlement to the Indemnifying Party and receiving
the Indemnifying Party's prior written consent, which may not


                                    -47-




be unreasonably withheld, on such terms as the Indemnified Party, in good
faith, may deem appropriate, and

          (b) the Indemnifying Party may participate in (but not control) the
defense of such action, with its own counsel at its own expense. The Parties
shall make available to each other all relevant information in their
possession relating to any such Third Person Claim and shall cooperate in
the defense thereof.

     8.7. EXCLUSIVE REMEDY. Except as otherwise expressly provided in this
Agreement, the provisions of this Article VIII shall constitute the sole and
exclusive remedy of the Parties from and after the Closing with respect to
any claims resulting from or arising out of the provisions of this Agreement
or the transactions contemplated hereby, other than claims determined by
final, non-appealable judgment of a court of competent jurisdiction to arise
from fraud.

delivered at any time following June 30, 2003 and prior to the Closing, in
the event any of the conditions to the Company's or Seller's obligations, as
set forth in Article VI hereof, have not been satisfied for any reason

a breach by the Company or the Sellers under this Agreement) or waived by

failure of such condition(s) to be so satisfied by reason of a breach by the
Buyer under this Agreement) or waived by the Buyer on or prior to June 30,
2003,

that, in addition to any other remedy to which the Parties may be entitled

Parties shall be entitled to specific performance of the terms thereof and
injunctive relief, without the necessity of proving money damages as an
inadequate remedy.

a waiver, by the Party against which the waiver is to be effective.

will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be
prohibited by or invalid under applicable law, such provision will be
ineffective only to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of
this Agreement.

     9.14. JURISDICTION. AFTER THE CLOSING, ANY LEGAL ACTION OR PROCEEDING
WITH RESPECT TO THIS AGREEMENT OR ANY DOCUMENT RELATED THERETO MAY BE
BROUGHT IN THE COURTS OF THE COUNTY OF PRINCE GEORGES, STATE OF MARYLAND OR

HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH
JURISDICTION. EACH PARTY WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT
