      day period shall constitute Buyer's approval of the Closing Net Asset
      Statement as so delivered. If Buyer timely provides an Objection Notice,
      Buyer and the Seller Representative shall promptly commence good faith
      discussions in an attempt to resolve any issues raised in the Objection
      Notice. If Buyer and the Seller Representative are unable to resolve such
      dispute within thirty (30) days after the delivery of the Objection
      Notice, such dispute shall be resolved by a Big Four accounting firm
      mutually acceptable to the Buyer and the Seller Representative or, in the
      absence of agreement, by a Big Four accounting firm selected by lot after
      eliminating Target's and Buyer's principal outside accountants. At or
      prior to the time such dispute is submitted to such accounting firm for
      resolution, Buyer shall provide a specific proposed Net Asset amount. The
      accounting firm so selected shall make its determination within thirty
      (30) days after delivery to it of the Objection Notice which determination
      shall be final and binding upon the Parties with respect to the
      Post-Closing Adjustment. The fees and expenses of such accounting firm
      shall be paid by the Buyer and the Sellers pro rata in accordance with
      each Party's asserted position relative to the accounting firm's final
      determination. The amount of the Net Assets on the Closing Net Assets
      Statement, as determined pursuant to this section, shall be the "Closing
      Date Net Assets." For purposes of this Agreement, "Net Assets" means the
      book value of total Assets (excluding, pursuant to the definition of
      "Assets," all Excluded Assets) owned by Target as of the Closing, less the
      book value of Target's liabilities as of the Closing, other than all
      Excluded Liabilities, each as determined in accordance with GAAP, applied
      on a basis consistent with, and following the accounting principles,
      procedures, policies and methods employed by Sellers in preparing Target's
      Most Recent Fiscal Year End balance sheet. The date on which the Closing
      Date Net Assets is determined shall be the "Determination Date." The
      "Post-Closing Adjustment" shall be computed by subtracting the Reference
      Amount from the Closing Date Net Assets.

            (ii) If the Post-Closing Adjustment is a positive number, Buyer
      shall pay to Harry P. Headley the amount of such excess plus the Holdback,
      in immediately available funds, within ten (10) business days after the
      Determination Date.

            (iii) If the Post Closing Adjustment is a negative number, the
      Holdback shall be retained and applied by Buyer, to the extent of the
      amount of the deficiency, and the remainder shall be paid to Seller
      Representative within ten (10) business days after the Determination Date.
      In the event the Post Closing Adjustment decreases the Purchase Price by
      more than the Holdback, any such remaining amount shall first be applied
      to reduce the principal amount of the Note, and then any additional
      portion of such remaining amount shall be paid to Buyer by the Seller
      Representative within ten (10) days after such amount is demanded by the
      Buyer.

      (d) Valuation of the Noncompetition Agreement and Noncompetition and
Nonsolicitation Provisions. Buyer and Sellers agree that the amount of the
consideration allocable to the Noncompetition Agreement shall be Twenty Thousand
Dollars ($20,000) and that the amount of the consideration allocable to the
Noncompetition and Nonsolicitation provisions of each Employment Agreement shall
each be Ten Thousand Dollars ($10,000).

waiver of all conditions to the obligations of the Parties to consummate the

4. Representations and Warranties Concerning Target. Each of Target and the
Seller Representative jointly and severally represent and warrant to the Buyer
that the statements contained in this section 4 are correct and complete as of
the date of this Agreement and will be correct and complete as of the Closing
Date (as though made then and as though the Closing Date were substituted for
the date of this Agreement throughout this section 4), except as set forth in
the disclosure schedule delivered by the Sellers to the Buyer on the date hereof
and initialed by the Parties (the "Disclosure Schedule"). The Disclosure
Schedule will be arranged in paragraphs corresponding to the lettered and
numbered paragraphs contained in this section 4.

      (a)   Corporate Existence and Capitalization.

            (i) Target is a corporation duly organized, validly existing, and in
      good standing under the laws of the State of New Jersey. Target is duly
      authorized to conduct business as a foreign corporation and is in good
      standing under the laws of each jurisdiction where such qualification is
      required, except where the lack of such qualification would not have a
      Material Adverse Effect. Section 4(a) of the Disclosure Schedule contains
      an accurate list of all jurisdictions in which Target is qualified to do
      business as a foreign corporation

            (ii) The authorized capital stock of Target consists solely of
      20,000 shares of common stock, no par value, of which 400 shares are
      issued and outstanding. All of the issued and outstanding shares of such
      common stock have been duly authorized and validly issued and are fully
      paid and nonassessable and are not subject to any preemptive rights. To
      the knowledge of Target, each of the Sellers owns of record and
      beneficially the number of shares of common stock set forth on section
      3(b) of the Disclosure Schedule with respect to such Seller, free and
      clear of all restrictions on transfer (other than restrictions under the
      Securities Act, state securities laws and the Shareholder Agreements,
      which Shareholder Agreements shall be terminated on or before the
      Closing), taxes, Security Interests, options, warrants, purchase rights,
      contracts, commitments, equities, claims and demands, other than such
      restrictions as may be contained in the Shareholder Agreements.

            (iii) Target has not issued or granted any outstanding options,
      warrants, rights or other securities convertible into or exchangeable or
      exercisable for shares of the capital stock of Target, any other
      commitments or agreements providing for the issuance of additional shares
      of the capital stock of Target, the sale of treasury shares, or for the
      repurchase or redemption of shares of Target's capital stock, or any
      obligations arising from canceled stock. There are no agreements of any
      kind which may obligate Target to issue, purchase, register for sale,
      redeem or otherwise acquire any of its securities or interests. There are
      no outstanding or authorized stock appreciation, phantom stock or similar
      rights with respect to Target.

            (iv) To the Knowledge of Target, except for the Shareholder
      Agreements, there are no voting trusts, shareholder agreements, proxies or
      other agreements in effect with respect to the voting or transfer of the
      Target Shares.


                                       13

      (b) Authorization of Transaction. Target has all requisite corporate power
and authority to own, lease and operate the properties owned by it, to conduct
its business as it is presently being conducted, to execute and deliver this
Agreement and to perform its obligations hereunder. This Agreement has been duly
executed and delivered by Target.

      (c) Noncontravention. Except as set forth in section 4(c) of the
Disclosure Schedule, neither the execution and the delivery of this Agreement,
nor the consummation of the transactions contemplated hereby, will (i) violate
any constitution, statute, regulation, rule, injunction, judgment, order,
decree, ruling, charge, or other restriction of any government, governmental
agency, or court to which Target or any of the Assets is subject or any
provision of the charter or bylaws of Target or (ii) conflict with, result in a
material breach of, constitute a default under, result in the acceleration of,
create in any party the right to accelerate, terminate, modify, or cancel, or
require any notice under any Contract to which Target is a party or by which it
is bound or to which any of the Assets is subject (or result in the imposition
of any Security Interest upon any of the Assets), except where, prior to or
simultaneously with the Closing, such Contract is being terminated or the
consent of the other party thereto will have been obtained. Target does not need
to give any notice to, make any filing with, or obtain any authorization,
consent, or approval of any government or governmental agency in order for the
Parties to consummate the transactions contemplated by this Agreement, except
where the failure to give notice, to file, or to obtain any authorization,
consent, or approval would not have a Material Adverse Effect on the business,
financial condition, operations, results of operations, or future prospects of
the Business, or on the ability of the Parties to consummate the transactions
contemplated by this Agreement, and except for the filing contemplated by
section 5(b) below. Notwithstanding the foregoing, Target and the Seller
Representative make no representation as to the applicability of 41 U.S.C.
section 15 (the "Assignment of Contracts Act") or 31 U.S.C. section 3727 (the
"Assignment of Claims Act").

      (d) Title to Assets. Except as set forth in section 4(d) of the Disclosure
Schedule, Target has good title to, or a valid leasehold interest in, or, as to
Intellectual Property, valid license of, the property and assets used by it, or
shown on the Most Recent Balance Sheet or acquired after the date thereof and
shown on the Closing Net Asset Statement, free and clear of any Security
Interests. Except as contemplated by this Agreement, the Assets are all of the
assets necessary for the conduct of the Business as currently conducted.

      (e) Books and Records. Target has made and kept (and given Buyer access
to) Books and Records and accounts, which, in reasonable detail, accurately and
fairly reflect in all material respects, Target's business. The minute books of
Target to which Buyer has been given access do not omit reference to any
corporate transaction of Target which will continue in effect or remain binding
on Target or any of the Assets after the Closing.

      (f) Subsidiaries. Target has no Subsidiaries.

      (g) Financial Statements. Attached hereto as Exhibit D are the following
financial statements (collectively the "Financial Statements"): (i) reviewed
balance sheets and reviewed statements of income, changes in stockholders'
equity, and cash flow as of and for the fiscal years ended December 31, 1997
(the "Most Recent Fiscal Year End"), December 31, 1996 and


                                       14
<PAGE>

December 31, 1995 for Target, and (ii) unaudited balance sheets and statements
of operations, (the "Most Recent Financial Statements") as of and for the one
month ended January 31, 1998 (the "Most Recent Fiscal Month End") for Target.
The Financial Statements described above present fairly the financial condition
of Target and the Business as of such dates and the results of operations of
Target for such periods. The Financial Statements (including the notes thereto )
have been prepared in accordance with GAAP applied on a consistent basis
throughout the periods covered thereby; provided, however, that the Most Recent
Financial Statements are subject to normal year-end adjustments and lack
footnotes and other presentation items.

      (h) Projections. Seller Representative has delivered to Buyer projected
income statements and balance sheets of the Business for the 1998 and 1999
fiscal years (the "Projections"), which are attached as Exhibit E hereto. The
Projections were prepared in good faith and represent management's current
estimate, based on Target's current Knowledge, of the financial position and
results of operations of the Business for the periods indicated. To Target's
Knowledge as of the date hereof and as of the Closing Date, the assumptions
forming the basis of such Projections are reasonable. Buyer recognizes that the
basis for such Projections assumes the "stand alone" operation of the Business.
Buyer further recognizes that future circumstances and events may affect the
actual performance of the Business, and there can be no assurance that such
performance will be in accordance with the Projections.

      (i) Events Subsequent to Most Recent Fiscal Year End. Since the Most
Recent Fiscal Year End, there has not been any Material Adverse Change in
Target, or the Business, taken as a whole. Specifically, without limiting the
generality of the foregoing, since the Most Recent Fiscal Year End, except as
contemplated in this Agreement or as set forth in the Disclosure Schedule, there
has not been any:

            (i) change in accounting methods, principles, or practices by

      benefit granted, made or accrued, contingently or otherwise, for or to the
      credit of, any director, officer or other employee, except as provided in
      any employment agreement (including any union contract) between Target and
      any such persons or in any employee plan, and except for any increases in
      the normal course of business;

            (v) addition to or modification of the Employee Benefit Plans,
      arrangements or practices affecting the officers, directors, or Business
      Employees of Target other than (A) contributions made for 1997 in
      accordance with the normal practices of the Target, or

      Assets, other than in the ordinary course of business, except as approved
      in writing in advance by Buyer and except for transfers of the Excluded
      Assets;

            (viii) capital expenditure or the execution of any lease or any
      incurring of liability therefor by Target involving payments in excess of
      $10,000 or $50,000 in the aggregate with respect to any such expenditure
      or lease or otherwise not substantially in accordance with Target's past
      practice;

            (ix) any indebtedness incurred by Target for borrowed money or any
      commitment to borrow money entered into by Target, or any loans made or
      agreed to be made by Target except for loans constituting Excluded Assets
      and indebtedness incurred in the ordinary course of business as part of
      Target's Inventory financing or under the existing working capital line of
      credit;

            (x) revaluation by Target of any of the Assets, including, without
      limitation, writing-off notes, or writing-off accounts receivable except
      with respect to accounts receivable written off in the ordinary course of
      business;

            (xi) payment or declaration of any dividends, distributions with
      respect to any of the Target Shares, or redemption, repurchase or

      the things described in the preceding clauses (i) through (xi), other than

(whether absolute or contingent, whether accrued or unaccrued, whether

liability for Taxes), except for (i) liabilities set forth on the Most Recent
Financial Statements (or in any notes to the December 31, 1997 Financial
Statements), (ii) liabilities which have arisen after the Most Recent Fiscal
Month End in the ordinary course of business, and (iii) Excluded Liabilities.

      (k) Legal Compliance. Target has complied in its operations in all
material respects with all applicable statutes and governmental rules,
regulations and Permits. No action, suit, proceeding, hearing, or, to Seller
Representative's Knowledge, investigation, charge, complaint, claim, demand, or
notice has been filed or commenced against Target alleging any failure so to
comply, nor, to the Knowledge of Seller Representative, are any such actions
threatened.

            (i) Filing of Tax Returns. Target has timely filed with the
      appropriate taxing authorities all returns (including without limitation
      information returns and other material information) in respect of Taxes
      required to be filed through the date hereof and will timely file any such
      returns required to be filed on or prior to the Closing Date, in each

      any Taxes.

            (ii) Payment of Taxes. All Taxes that accrue or are payable by
      Target in respect of taxable periods that end on or before the Closing
      Date and for any taxable periods that begin before the Closing Date and
      end thereafter to the extent such Taxes are attributable to the portion of
      such period ending on the Closing Date (such period being referred to
      herein as a "Pre-Closing Partial Period"), as determined under the closing
      of the books method of allocation, have (or will have, on or before the

      claims for or relating to any additional Tax liability, and there are no

      Taxes that in the reasonable judgment of the Target is likely to result in
      a material additional liability of Target for Taxes. Except as set forth
      in such Section, neither Target nor Seller Representative has been
      notified that any taxing authority intends to audit a return for any
      period.

      in accounts for such purpose.

            (x) Disclosure Statements. Target has not filed with respect to any
      item a disclosure statement pursuant to Code Section 6662 or any

      (m)   Real Property.

            (i) Target owns only the real property described on section 4(m)(i)
      of the Disclosure Schedule (the "Owned Real Property"). Target's title to
      and possession of the Owned Real Property is without any lien,
      encumbrance, covenant, condition or adverse claim of any kind except as
      shown on the owner's title insurance policy and deed with respect thereto,
      as previously furnished to Buyer.

            (ii) Section 4(m)(ii) of the Disclosure Schedule lists and describes
      briefly all real property leased or subleased to Target for use in the

      Buyer correct and complete copies of the leases and subleases listed in
      section 4(m)(ii) of the Disclosure Schedule (as amended to date). With
      respect to each lease and sublease listed in section 4(m)(ii) of the
      Disclosure Schedule, the lease or sublease is legal, valid, binding,
      enforceable, and in full force and effect. Target has not assigned,
      transferred, conveyed, mortgaged, deeded in trust, or encumbered any
      interest in any such leasehold or subleasehold. Target enjoys peaceful

      fulfilled in all material respects all the obligations required to be
      performed by it through the date hereof with respect to such Leased Real

      governmental authorities (including Permits and material certificates of
      occupancy or other similar certificates permitting lawful occupancy)
      required in connection with the present use of the Leased Real Property.

            (iv) Target has not received notice of any special assessment
      relating to any Real Property for which Target would be liable under any

having a gross book value equal to or greater than $10,000 constituting part of

Target has not interfered with, infringed upon, misappropriated, or violated any
Intellectual Property rights of third parties in any material respect, and

      items of Intellectual Property owned by Target and used in the Business,
      the loss of which could reasonably be expected to have a Material Adverse
      Effect ("Material Intellectual Property"), and identifies each license,
      agreement, or other permission which Target has granted to any third party
      with respect to any such Material Intellectual Property (together with any
      exceptions). Copies of all documents of Material Intellectual Property
      have been made available to Buyer. With respect to each item of
      Intellectual Property required to be identified in section 4(o)(i) of the
      Disclosure Schedule:

                  (B) no action, suit, proceeding, hearing, investigation,
      charge, complaint, claim, or demand is pending or, to the Knowledge of
      Target, threatened which challenges the legality, validity,
      enforceability, use, or ownership of the item.

            (ii) Section 4(o)(ii) of the Disclosure Schedule identifies each
      material item of Intellectual Property that any third party owns and that
      Target uses in the Business

      the item is legal, valid, binding, enforceable, and in full force and
      effect; provided, however, that no representation is made as to the
      ownership of any Material Non-Owned Intellectual Property or as to the
      right of the Target's licensor, sublicensor or grantor to grant any such
      license, sublicense, agreement or permission;

                  (B) neither Target nor, to the Knowledge of Target, any other
      party to the license, sublicense, agreement, or permission is in breach or
      default which would permit termination, modification, or acceleration
      thereunder; and

                  (C) Target has not granted any sublicense or similar right
      with respect to the license, sublicense, agreement, or permission.

            (iii) With respect to each software license or software sublicense

information contained in this section 4 not misleading. Buyer agrees that, if
prior to Closing Buyer obtains Knowledge that any of the representations or
warranties in this section 4 is inaccurate or misleading in any material
respect, Buyer will give Seller Representative notice thereof and will either
(i) give Seller Representative a reasonable opportunity to cure such

or destroy all tangible embodiments (and all copies) of the Confidential
Information, including all information prepared by the receiving party or such
receiving party's representatives, which are in its possession or the possession
of its representatives. Any provision hereof to the contrary notwithstanding,

information relating solely to Target (other than information relating to the
Excluded Assets or Excluded Liabilities).

      (g) Consents; Reasonable Effort; Cooperation. Target and Sellers will make

      (h) Notice of Developments. Buyer will give written notice to the Seller
Representative of any development causing a breach of any of the representations
and warranties in section 3(a) which has not previously been disclosed to the

agents' due diligence investigation with regard to this Agreement.

      (i) Exclusivity. Prior to the Closing or other termination of this
Agreement in accordance with the terms hereof, none of the Sellers will (and the
Sellers will not cause or permit Target to) accept an offer from any Person
relating to the acquisition of any capital stock or other voting securities, or
any portion of the Assets, of Target, other than in the ordinary course of
business (including any acquisition structured as a merger, consolidation, or
share exchange). None of the Sellers will vote their Target Shares in favor of
any such nonpermitted acquisition structured as a merger, consolidation, or
share exchange.

      (j) No Solicitations. From the date hereof through the Closing Date or
termination of this Agreement in accordance with the terms hereof, neither
Target nor any Seller shall directly or through an agent solicit, participate in
or initiate discussions or negotiations with any Person or group of Persons
(other than Buyer or any of its Affiliates) concerning any merger, sale of
assets, sale of shares of capital stock or similar transactions involving Target
or the Business.

      (k) Employee Matters. Upon the Closing, Buyer will cause Target to
continue the employment of each employee of Target ("Business Employees") except
for such individuals as are designated on section 4(v) of the Disclosure
Schedule (the "Excluded Employees") at a comparable level of salary and
comparable benefits as currently provided to such Business Employee by Target.
Notwithstanding the foregoing, Buyer shall not thereafter be restricted from any
modification in terms of employment or termination of the Business Employees in
the ordinary course of business. It is acknowledged and agreed that Buyer shall
have no obligation to pay, or cause Target after the Closing to pay, any
severance or termination payments to any Excluded Employee by virtue of the
termination of their employment with Target effective as of the Closing.

      (l) Updated Contract Backlog and Financial Statements. Prior to the
Closing, (i) Target shall provide an updated estimate of the amounts anticipated
to be recognized during the remaining term of the Government Contracts, prepared

            (i) In case at any time after the Closing any further action is

8. Consents To Assignment or Novation; Risk of Loss.

      (a) Anything in this Agreement to the contrary notwithstanding, this
Agreement shall not constitute an agreement to assign or novate any Contract, or
any claim or right or any benefit arising thereunder or resulting therefrom, if
an attempted assignment or novation thereof, without the consent of a third
party thereto, would constitute a breach thereof or in any way adversely affect
the rights of Target thereunder. If such consent is not obtained, or if an
attempted assignment or novation thereof would be ineffective or would affect
the rights thereunder so that Target would not receive all such rights, Sellers
and Buyer will cooperate, in all reasonable respects but without material cost
to Sellers which is not promptly reimbursed by Buyer, to obtain such consent as
soon as practicable and, until such consent is obtained, to provide to Target
the benefits under any Contract to which such consent relates (with Target
responsible for all the liabilities and obligations thereunder). Recognizing
that any action taken by Sellers pursuant to this section 8(a) is at the request
of and for the benefit of Buyer, Buyer agrees to indemnify and hold harmless
Sellers from and against any claim, loss, liability, damages, cost or expense
(including reasonable attorneys' fees and expenses) arising from or related to
any breach or default under such contracts by Target following the Closing Date
or any action taken by Sellers pursuant to the terms of this section 8(a) at the
request of Buyer. No failure of a Contract to be transferred shall be deemed to
affect any amount payable to Sellers pursuant to any provision of section 2 of
this Agreement (subject to any set-off rights expressly provided for in this
Agreement), except to the extent such failure is the result of any breach by
Target or any Seller of any covenant, representation or warranty contained
herein.

      (b) Risk of Loss. If any material portion of the tangible Assets is
destroyed or damaged by fire or any other cause prior to the Closing Date which
destruction or damage disables Target from carrying on, or materially impairs
Target's ability to carry on, a material part of the Business, the Seller
Representative shall give written notice to Buyer as soon as reasonably
practicable after, but in any event within five (5) business days of, Seller
Representative obtaining Knowledge thereof, including information as to the
amount of insurance, if any,


                                       33
<PAGE>

believed to cover such destruction or damage. In such event, prior to the
Closing, Buyer shall have the option, which shall be exercised by written notice
to the Seller Representative within ten (10) days after receipt of the Seller
Representative's notice or, if there are not ten (10) days prior to the Closing
Date, as soon as practicable prior to the Closing Date, of (i) closing with such
Assets in their destroyed or damaged condition, in which event Buyer shall be
entitled to the proceeds of any insurance or other proceeds payable with respect
to such loss and, subject to the limitations set forth in section 9 hereof, to
indemnification for any uninsured portion of such loss to the extent provided by
such section 9, and the full purchase price shall be paid, (ii) if agreed by the
Seller Representative, excluding such Assets from the transaction contemplated
hereby, in which case the purchase price shall be reduced by the amount
allocated to such Assets, as mutually agreed between the Parties, and Sellers
shall be entitled to promptly receive any insurance or other proceeds payable
with respect to such loss, or (iii) after providing Target with a reasonable
opportunity to repair such destruction or damage, terminating this Agreement in
accordance with section 11.

9. Survival; Indemnification.

      (a) Survival of Representations and Warranties. All of the representations
and warranties of the Parties contained in this Agreement shall survive the
Closing and continue in full force and effect for a period of one (1) year
thereafter except (i) those representations made with respect to the matters set
forth in sections 4(a) (ii) and (iii), 4(j), 4(l), 4(w), 4(x) and 4(z) and any
claim with respect thereto, and any matters arising by reason of any DCAA audits
for periods prior to and through the Closing Date, and any claim with respect
thereto, shall survive until ninety (90) days after the expiration of the
applicable statute of limitations (with extensions) with respect to the matters
addressed in those sections, and (ii) as otherwise expressly set forth herein.
The termination after Closing of the representations and warranties provided
herein shall not affect the rights of a party in respect of any claim made by
such party in a writing received by the other party prior to the expiration of
the applicable survival period provided herein.

      (b) Indemnification Provisions for Benefit of the Buyer. In the event
Target or Buyer suffers Adverse Consequences after the Closing as a result of
(i) the breach by Sellers or Target of any of their respective representations
and warranties contained in section 3(b) or 4 hereof or of any covenant in
section 2, 5, 6 or 10 hereof, (ii) any third party claim with respect to the
operation of the Business or other actions of Target prior to the Closing Date
(except to the extent any such claim constitutes a liability included on the
Closing Net Asset Statement), (iii) any Excluded Liability or Pre-Closing
Environmental Liability, or (iv) any material breach or default by Target under
any of the Contracts prior to the Closing Date (each, a "Buyer Indemnification
Matter"), provided that the Buyer makes a written claim for indemnification
against Seller Representative pursuant to section 13(h) below within the
survival period described above, then the Seller Representative agrees to
indemnify and hold harmless the Buyer and its Affiliates, and their respective
directors, officers, shareholders and employees (collectively, the "Buyer
Parties") from and against any Adverse Consequences the Buyer Parties may suffer
through and after the date of the claim for indemnification (including any
Adverse Consequences the Buyer Parties may suffer after the end of any
applicable survival period) directly resulting from or caused by such Buyer
Indemnification Matter (calculated as set forth in subsection (e) below);
provided, however, that Seller Representative shall not have any


                                       34
<PAGE>

obligation to indemnify any of the Buyer Parties from or against any Adverse
Consequences resulting from any Buyer Indemnification Matter until the Buyer
Parties have suffered Adverse Consequences by reason of all such Buyer
Indemnification Matters in excess of $50,000 in the aggregate, after which point
Seller Representative will be obligated only to indemnify the Buyer Parties from
and against further such Adverse Consequences); further provided, that the
limitations set forth above shall not apply to (x) any breach of a covenant set
forth in sections 2, 5, 6 or 10 of this Agreement, or of the representation set
forth in section 4(l)(ix), hereof, or (y) any indemnification for any Excluded
Liability, except such excluded Liabilities as are described in clause (a) of
the definition thereof and are not described in any other clause of such
definition. Notwithstanding the foregoing, Seller Representative shall have no
liability for Adverse Consequences arising from the breach of the representation
set forth in section 4(q) except as follows. If and to the extent any
Transferred Receivable is not collected by Buyer within ninety (90) days after
the later of the Closing Date or the date on which the same was billed (the
"Preliminary Collection Date"), Buyer shall notify Seller representative of such
non-collection. For a period of ninety (90) days after the Preliminary
Collection Date, Seller Representative shall have the right to work together
with Buyer in an attempt to collect any such uncollected Transferred
Receivables; provided that Seller Representative shall not take any action which
could reasonably be deemed to have an adverse affect on any ongoing relationship
between Target or Buyer and the account debtor on any such Transferred
Receivable. If and to the extent that, at the end of such further ninety-day
period, any such Transferred Receivable has not been fully paid over to Buyer,
one-half (1/2) of any remaining uncollected amount thereof shall be deemed an
Adverse Consequence as to which Seller Representative shall have an
indemnification responsibility pursuant to this section 13(b).

      (c) Indemnification Provisions for Benefit of Sellers. In the event (i)
the Buyer breaches any of its representations, warranties, and covenants
contained herein, or (ii) after the Closing, Target takes or fails to take any
action under any Contract which constitutes part of the Assets, or fails fully
and timely to perform its obligations with respect to any liabilities existing
as of the Closing and not constituting Excluded Liabilities (each, a "Seller
Indemnification Matter"), and a claim is made against any of the Sellers or any
of the Seller Parties (as defined below) with respect thereto, provided that any
of the Sellers or such Seller Party makes a written claim for indemnification
against the Buyer pursuant to section 13(h) below within the survival period
described above, then the Buyer agrees to indemnify, save, and hold harmless any
of such Sellers and any Sellers' Affiliates, and their respective directors,
officers, shareholders and employees (collectively, the "Seller Parties") from
and against any Adverse Consequences such Seller Parties may suffer through and
after the date of the claim for indemnification (including any Adverse
Consequences the such Seller Parties may suffer after the end of any applicable
survival period) resulting from or caused by the Seller Indemnification Matter
(calculated as set forth in subsection (e) below; provided, however, that the
Buyer shall not have any obligation to indemnify the Sellers hereunder until the
Sellers have suffered Adverse Consequences by reason of all Seller
Indemnification Matters in excess of $50,000 in the aggregate, after which point
the Sellers shall be entitled to indemnification for all such Adverse
Consequences in excess of such amount; and further provided that the limitations
set forth above shall not apply to claims for breaches of any covenant set forth
in section 2, 5 or 6 of this Agreement.


                                       35
<PAGE>

      (d)   Matters Involving Third Parties.

            (i) If any third party shall notify any Party (the "Indemnified
      Party") with respect to any matter (a "Third Party Claim") which may give
      rise to a claim for indemnification against any other Party (the
      "Indemnifying Party") under this section 9, then the Indemnified Party
      shall promptly notify each Indemnifying Party thereof in writing within
      ten (10) days after the Indemnified Party has Knowledge thereof; provided,
      however, that the Indemnified Party's failure timely to provide such
      notice shall not bar the Indemnified Party's right to indemnification
      hereunder if the Indemnified Party can establish that such failure has not
      materially prejudiced the Indemnifying Party's ability to defend the claim
      or proceeding.

            (ii) Any Indemnifying Party will have the right, at its sole cost
      and expense, to assume the defense of the Third Party Claim with counsel
      of his or its choice reasonably satisfactory to the Indemnified Party at
      any time within ten (10) business days after the Indemnified Party has
      given notice of the Third Party Claim; provided, however, that the
      Indemnifying Party shall not have the right to control the defense of any
      such claim or proceeding unless it has acknowledged in writing its
      obligation to indemnify the Indemnified Party from liability arising from
      such claim or proceeding pursuant to this section 9 (subject to any
      applicable limitations set forth in subsections 9(b) and 9(c) above), and
      then, and periodically thereafter, provides the Indemnified Party with
      reasonably sufficient evidence of the ability of the Indemnifying Party to
      satisfy its obligations under this section 9 with respect to such Third
      Party Claim. In the event that the Indemnifying Party assumes the defense
      as set forth hereunder, the Indemnifying Party shall conduct the defense
      of the Third Party Claim with reasonable diligence thereafter. The
      Indemnified Party may retain separate co-counsel at its sole cost and
      expense and participate in the defense of the Third Party Claim; provided
      that Indemnifying Party's counsel will consult with such co-counsel, but
      shall remain in sole control of such action.

            (iii) So long as the Indemnifying Party has assumed and is
      conducting the defense of the Third Party Claim in accordance with section
      9(d)(ii) above, (A) the Indemnifying Party will not consent to the entry
      of any judgment or enter into any settlement with respect to the Third
      Party Claim without the prior written consent of the Indemnified Party
      (not to be withheld, conditioned or delayed unreasonably) unless the
      judgment or proposed settlement involves only the payment of money damages
      by one or more of the Indemnifying Parties and does not impose any
      material injunction or other equitable relief upon the Indemnified Party
      and (B) the Indemnified Party will not consent to the entry of any
      judgment or enter into any settlement with respect to the Third Party
      Claim without the prior written consent of the Indemnifying Party (not to
      be withheld, conditioned or delayed unreasonably).

            (iv) In the event none of the Indemnifying Parties assumes and
      conducts the defense of the Third Party Claim in accordance with section
      9(d)(ii) above, however, (A) the Indemnified Party may defend against the
      Third Party Claim in any manner he or it reasonably may deem appropriate;
      provided that the Indemnified Party shall conduct the


                                       36
<PAGE>

      defense of the Third Party Claim with reasonable diligence and (B) the
      Indemnifying Parties will remain responsible for any Adverse Consequences
      the Indemnified Party may suffer resulting from, arising out of, relating
      to, in the nature of, or caused by the Third Party Claim to the extent
      provided in this section 9. In such event, (1) the Indemnifying Party may
      retain separate co-counsel at its sole cost and expense and participate in
      the defense of the Third Party Claim, and the Indemnified Party's counsel
      will consult with such co-counsel but shall remain in sole control of such
      proceeding, and (2) the Indemnified Party will not consent to the entry of
      any judgment or enter into any settlement with respect to the Third Party
      Claim without the prior written consent of the Indemnifying Party (not to
      be withheld, conditioned or delayed unreasonably).

      (e) Determination of Adverse Consequences. The Parties shall make
appropriate adjustments for tax consequences and insurance coverage and take
into account the time cost of money (using the Applicable Rate as the discount
rate from the later of the Closing Date or (x) the date of incurrence of such
Adverse Consequences, if not involving a Third Party Claim, or the date of such
Third Party Claim) in determining Adverse Consequences for purposes of this
section 9. All indemnification payments under this section 9 shall be deemed
adjustments to the Purchase Price.

      (f) Exclusive Remedy. The Buyer and Sellers acknowledge and agree that,
except (i) as otherwise set forth in this Agreement, (ii) with respect to actual
fraud, intentional misconduct and violations of law, and (iii) for claims
brought for breaches of or default under any Ancillary Agreement, the foregoing
indemnification provisions in this section 9, together with any other
indemnification provisions expressly set forth in this Agreement, shall be the
exclusive remedy of the Buyer and Sellers with respect to matters relating to
the Business and the Assets and the transactions contemplated by this Agreement.
Without limiting the foregoing, Buyer acknowledges that Target's inclusion as a
Party to this Agreement is not intended to, nor shall it have the effect of,
enlarging the liability of the Seller Representative beyond the limitations set
forth in this section 9.

      (g) Right of Set-Off. In addition to any other remedies, any Claims under
this section 9 are, at the option of the Buyer, subject to the following right
of set-off. At the Buyer's election, the principal amount of the Note is subject
to adjustment following the Closing for any aggregate amount finally determined
to be payable by or to Buyer or the Seller Representative pursuant to this
section 9. Any such adjustment is intended as, and shall be treated by the
Parties as, an adjustment to the Total Consideration. If the principal amount of
the Note is adjusted pursuant to this subsection (g)(ii), such adjustment shall
be deemed to be made effective as of the later of (i) Closing Date, or (ii) the
date such Claim arose, and all interest that may have accrued on the principal
amount so canceled or added shall also be deemed to be retroactively canceled or
added, effective as of such date. Upon any adjustment of the principal amount of
the Note, Seller Representative shall, upon request of Buyer, surrender the
outstanding Note for a replacement Note reflecting the adjusted principal
amount, and Buyer shall, upon request of Seller Representative, execute and
deliver to Seller Representative such replacement Note.

10. Tax Matters. The following provisions shall govern the allocation of
responsibility as between Buyer and Sellers for certain tax matters:


                                       37
<PAGE>

      (a) Buyer shall, and shall cause Target to, promptly provide and make
available to the Seller Representative all information he may request for the
purpose of preparing and filing any such return or working on any such audit.

      (b) Buyer and Sellers shall cooperate fully, as and to the extent
reasonably requested by the other party, in connection with the filing of any
Tax Returns for Target and any audit, litigation or other proceeding with
respect to Taxes. Such cooperation shall include the retention and (upon the
other party's request) the provision of records and information which are
reasonably relevant to any such 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.

      (c) Buyer and Sellers further agree, upon request, to use all reasonable
efforts to obtain any certificate or other document from any governmental
authority or any other Person as may be necessary to mitigate, reduce or
eliminate any Tax that could be imposed (including, but not limited to, with
respect to the transactions contemplated hereby).

      (d) Buyer and Sellers further agree, upon request, to provide each other
party with all information that either party may be required to report pursuant
to section ss.6043 of the Code and all Treasury Department Regulations
promulgated thereunder.

      (e) Any transfer, documentary, sales, use, stamp, registration and other
such Taxes and fees (including any penalties and interest) incurred in
connection with this Agreement and the transactions contemplated hereby, shall
be paid half by Sellers and half by Buyer when due, and Buyer will file all
necessary Tax Returns and other documentation with respect to all such transfer,
documentary, sales, use, stamp, registration and other Taxes and fees, and, if
required by applicable law.

      (f) Sellers shall have no liability with respect to any Taxes of any kind
with respect to Target or its Assets or operations (i) with respect to all tax
periods beginning after the Closing Date, (ii) with respect to any tax period of
Target beginning before the Closing Date and ending after the Closing Date, but
only with respect to the portion thereof beginning after the Closing Date, or
(iii) with respect to any Pre-Closing Partial Period, but only to the extent
such Taxes were paid prior to Closing or are provided for on the Closing Net
Asset Statement. Except as set forth in subsection 10(f) above, Sellers shall
have sole liability for all Taxes that arise from the actual sale of the Target
Shares or any deemed sale of the Assets occurring as a result of the Election.

      (g) Contests. Sellers and Buyer agree to give prompt notice to each other
of any proposed adjustment to Taxes for periods of Target ending on or prior to
the Closing Date or any Pre-Closing Partial Period. Sellers and Buyer shall
cooperate with each other in the conduct of any audit or other proceedings
involving Target for such periods and each party may participate at its own
expense. Seller Representative shall have the right to control the conduct of
any such audit or proceeding for which Seller Representative agrees that any
resulting Tax allocable to any period prior to or including the Closing Date is
covered by the indemnity provided in Section 9 of this Agreement, (such audit or
other proceeding, a "Sellers' Contest"), provided that: (i) Seller


                                       38
<PAGE>

Representative shall keep Buyer informed regarding the progress and substantive
aspect of any Sellers' Contest and (ii) Seller Representative shall not
compromise or settle any Sellers' Contest without Buyer's consent, which consent
may not be unreasonably withheld. If Seller Representative chooses to direct a
Sellers' Contest, Buyer shall cause powers of attorney authorizing Seller
Representative to represent Target before the relevant taxing authority and such
other documents as are reasonably necessary for Seller Representative to control
the conduct of any Sellers' Contest.

      (h) Section 338(h)(10) Election and Allocation of Purchase Price. (i) Each
Seller and Buyer shall jointly make the election provided for by Section
338(h)(10) of the Code and any corresponding elections under state, local or
foreign tax law (the "Election") with respect to the purchase and sale of Target
Shares. Seller Representative and Buyer shall provide to the other all necessary
information to permit the Election to be made. Seller Representative and Buyer
shall, as promptly as practicable following the Closing Date, take all actions
necessary and appropriate (including filing IRS Form 8023-A and other such
forms, returns, elections, schedules, attachments and other documents as may be
required (collectively, the "Forms")) to effect and preserve a timely election.

            (i) In connection with the Election, Buyer and Seller Representative
      shall mutually determine (i) the amount of the modified aggregated deemed
      sales price ("MADSP") of the Target Shares (within the meaning of Treas.
      Reg. Section 1.338(h)(10)-1(f)) and (ii) the proper allocation of the
      MADSP among the Assets in accordance with Treas. Reg. Section
      1.338(h)(10)-1(f); provided, however that for such purpose, the
      depreciable tangible assets of Target shall have the value of such assets
      as set forth on the balance sheet of Target dated January 31, 1998. The
      allocations referred to in the preceding sentence are referred to herein
      as the "Allocations." Buyer and Seller Representative will calculate the
      gain or loss, if any, in a manner consistent with the Allocations, and
      Buyer and each Seller will not take any position inconsistent with the
      Allocations in any Tax Return (subject to appropriate adjustments pursuant
      to Treas. Reg. ss. 1.338(h)(10)-1(f)(4)).

            (ii) Buyer shall prepare IRS Form 8594 allocating the Purchase Price
      (including any Adjustment Amount under section 2.5 hereof) in accordance
      with Section 1060 of the Code in light of the procedure set forth in the
      preceding subsection (i) and such other information as required by Form
      8594, and shall forward it within one hundred twenty (120) days after
      Closing to Seller Representative for his approval, which approval shall
      not be unreasonably withheld. In accordance with Code Section 1060(e),
      Buyer and each of the Seller Representative shall file with their
      respective federal Income Tax Returns for the tax year in which the
      Closing occurs, IRS Form 8594 containing the information agreed upon by
      the parties pursuant to the immediately preceding sentence.

            (iii) Buyer shall prepare, after consultation with Seller
      Representative, each Form and shall within thirty (30) days prior to the
      latest date for the filing of each Form, submit each such Form to Seller
      Representative for Seller Representative's approval, which approval shall
      not be unreasonably withheld.

11. Termination.

      (a) Termination of Agreement. Either Buyer or Seller Representative may
terminate this Agreement as provided below:

            (i) Buyer and Seller Representative may terminate this Agreement by
      mutual written consent at any time prior to the Closing;

            (ii) Buyer may terminate this Agreement by giving written notice to
      the Seller Representative at any time prior to the Closing (A) in the
      event any of the Sellers has breached any material representation,
      warranty, or covenant contained in this Agreement in any material respect,
      the Buyer has notified the Seller Representative of the breach, and the
      breach has continued without cure for a period of ten (10) days after the
      notice of breach or (B) if the Closing shall not have occurred on or
      before the Termination Date (as defined below), by reason of the material
      failure of any condition precedent under section 7(a) hereof (unless the
      breach of any representation, warranty, or covenant of Buyer contained in
      this Agreement is a material factor therein); or (C) if consummation of
      the transactions contemplated by this Agreement is enjoined, prohibited or
      otherwise restrained by the terms of a final, non-appealable order or
      judgment of a court of competent jurisdiction, or (D) if such termination
      would be authorized pursuant to section 8(b) hereof; and

            (iii) Seller Representative may terminate this Agreement by giving
      written notice to the Buyer at any time prior to the Closing (A) in the
      event the Buyer has breached any material representation, warranty, or
      covenant contained in this Agreement in any material respect, Seller
      Representative have notified the Buyer of the breach, and the breach has
      continued without cure for a period of ten (10) days after the notice of
      breach or (B) if the Closing shall not have occurred on or before the
      Termination Date, by reason of the material failure of any condition
      precedent under section 7(b) hereof (unless the breach of any
      representation, warranty, or covenant of Target or any Seller contained in
      this Agreement is a material factor therein); or (C) if consummation of
      the transactions contemplated by this Agreement is enjoined, prohibited or
      otherwise restrained by the terms of a final, non-appealable order or
      judgment of a court of competent jurisdiction.

            (iv) "Termination Date" means March 16, 1998; provided that Buyer
      may extend the Termination Date, by written notice to Seller
      Representative prior to any termination of this Agreement, to a date not
      later than March 31, 1998 in order to obtain satisfaction of the closing
      conditions set forth in Section 7.

            (v) Effect of Termination. If any Party terminates this Agreement
      pursuant to section 11(a) above, all rights and obligations of the Parties
      hereunder shall terminate without any liability of any Party to any other
      Party (except for any liability of any Party then in breach); provided,
      however, that (i) the confidentiality provisions contained in section 5(f)
      above shall survive termination, and (ii) the provisions of Article 12
      shall apply.


                                       40

      12.   Breach of Agreement.

            (a) Breach and Opportunity to Cure. If any party shall breach the
      terms of this Agreement or default in the performance of its obligations
      to be performed hereunder prior to Closing (a "Pre-Closing Default"), the
      nondefaulting party shall have the right to provide the applicable Seller
      and Seller Representative, or Buyer, as applicable, with notice specifying
      in reasonable detail the nature of such breach or default. If such breach
      or default has not been cured within the time period specified in section
      10 above, or by two (2) business days prior to the Closing Date, if
      earlier, then the party giving such notice may (i) terminate this
      Agreement by giving written notice to the defaulting party hereunder, (ii)
      extend the Closing Date for a period not in excess of ten (10) days, if
      such default has not been cured by the Closing Date (but no such extension
      shall constitute a waiver of such nondefaulting party's right to terminate
      as a result of such default), (iii) exercise the remedies available to
      such party pursuant to sections 12(b) or 12(c), as applicable, subject to
      the right of the other party to contest such action through appropriate
      proceedings, and/or (iv) proceed to Closing.

            (b) Sellers' Remedies for Failure of Buyer to Close. Buyer
      recognizes that if the transactions contemplated hereby are not
      consummated as a result of Buyer's default, Sellers would incur damages,
      the extent of which is extremely difficult and impractical to ascertain.
      The parties, therefore, agree that if this Agreement is terminated or the
      transactions contemplated are otherwise not consummated due to the
      material default of Buyer, Buyer shall pay to the Sellers an amount equal
      to $250,000, as liquidated damages, as Sellers' sole and exclusive remedy
      in full settlement of any damages of such failure to close. The parties
      agree that this sum shall be in lieu of any and all other relief to which
      Sellers might otherwise be entitled due to such failure to close.

            (c) Buyer's Remedies for Failure of Sellers to Close. Sellers agree
      that the Target Shares represent unique property that cannot be readily
      obtained on the open market and that Buyer would be irreparably injured if
      Sellers' obligation to sell the Target Shares to Buyer pursuant to this
      Agreement is not specifically enforced after default. Therefore, Buyer
      shall have the right to specifically enforce Sellers' obligation to sell
      the Target Shares to Buyer pursuant to this Agreement, and Sellers agree
      to waive the defense in any such suit that Buyer has an adequate remedy at
      law and to interpose no opposition, legal or otherwise, as to the
      propriety of specific performance as a remedy. In addition, Buyer shall be
      entitled to obtain from Sellers (in the event Buyer obtains the remedy of
      specific performance) court costs and reasonable attorneys' fees incurred
      by Buyer in enforcing its rights under this subsection (c). As a condition
      to seeking specific performance, Buyer shall not be required to have
      tendered the Cash Consideration, but shall be ready, willing and able to
      do so. In the event Buyer elects not to seek specific performance, but
      instead to terminate this Agreement as a result of any Pre-Closing
      Default, then Buyer shall be entitled to recover an amount equal to
      $250,000, as liquidated damages, as Buyer's sole and exclusive remedy in
      full settlement of any damages of such wrongful failure of Sellers to
      close. If, upon the default of Sellers in their obligation to close
      hereunder, Buyer seeks specific performance and does not prevail in its
      attempt to obtain specific performance, then Buyer shall be entitled to
      recover an amount equal to $250,000, as liquidated damages, as Buyer's
      sole and exclusive remedy in full settlement of any damages arising from
      such wrongful failure of Sellers to close. Buyer shall have the right to
      make any claim under this section 12(c) against Seller


                                       41
<PAGE>

Representative, without including a claim against any of the other Sellers. Any
claim of Buyer under this section 12(c) shall not be subject to any restrictions
or limitations on Seller Representative's liability set forth in section 9 of
this Agreement.

      (d) Parties' Remedies for Breach After Closing. For the breach by any of
the Parties of any covenant or agreement of such Party to be performed after the
Closing, the nondefaulting Party shall have the rights provided for under
section 9 hereof, and all other rights and remedies available for breach of
contract at law and in equity.

13. Miscellaneous.

      (a) Press Releases and Public Announcements. No Party shall issue any
press release or make any public announcement relating to the subject matter of
this Agreement without the prior written approval of the Buyer and the Seller
Representative; provided, however, that any Party may make any public disclosure
it believes in good faith is required by applicable law or any listing or
trading agreement concerning its publicly-traded securities (in which case the
disclosing Party will advise the other Parties prior to making the disclosure).

      (b) No Third-Party Beneficiaries. This Agreement shall not confer any
rights or remedies upon any Person other than the Parties and their respective
successors and permitted assigns; provided that the Buyer Parties and Seller
Parties are intended third party beneficiaries of section 9 hereof.

      (c) Entire Agreement. This Agreement (including the documents referred to
herein) constitutes the entire agreement among the Parties and supersedes any
prior understandings, agreements, or representations by or among the Parties,
written or oral, to the extent they relate in any way to the subject matter
hereof.

      (d) Further Assurances. Each Party to this Agreement shall execute such
documents and take, or cause Target to take, such further actions as may
reasonably be necessary to implement the provisions of this Agreement.

      (e) Succession and Assignment. This Agreement shall be binding upon and
inure to the benefit of the Parties named herein and their respective successors
and permitted assigns. No Party may assign either this Agreement or any of his
or its rights, interests, or obligations hereunder without the prior written
approval of the Buyer and Seller Representative; provided, however, that the
Buyer may (i) assign any or all of its rights and interests hereunder to one or
more of its Affiliates or as collateral to its financing source and (ii)
designate one or more of its Affiliates to perform its obligations hereunder (in
any or all of which cases the original Buyer nonetheless shall remain fully
responsible for the performance of all obligations hereunder designated as the
obligations of Buyer); and (iii) after the Closing Date, assign its rights and
obligations under this Agreement to any Person in connection with a sale or
other disposition of substantially all of the Business or substantially all of
Target's assets, without the consent of Sellers.
