This Current Report on Form 8-K/A amends and restates, in its entirety, the
Current Report on Form 8-K (date of report October 16, 1997), which was filed
with the Securities and Exchange Commission on October 16, 1997. This Form 8-K/A
also reports the acquisition of HIMSCORP, Inc. and Subsidiaries ("HIMSCORP") by
Iron Mountain Incorporated (the "Registrant").

Item 2.  Acquisition or Disposition of Assets

HIMSCORP, Inc. and Subsidiaries

On October 31, 1997, the Registrant acquired all of the outstanding capital
stock of HIMSCORP, the leading national provider of records management services
for hospitals and other organizations in the healthcare industry. The
acquisition, effective November 1, 1997, was structured as a tax free
reorganization for total consideration, including transaction costs, of $98.8
million, including 1.2 million shares of Iron Mountain Common Stock ("Common
Stock") preliminarily valued at $46.2 million and cash and assumed indebtedness
of $52.6 million.

The cash consideration was financed primarily by a portion of the net proceeds
from the sale of the Registrant's $250 million in aggregate principal amount of
8.75% Senior Subordinated Notes due 2009.

The assets acquired by the Registrant include primarily accounts receivable,
office equipment, furniture and fixtures, motor vehicles, racking and shelving
and intangible personal property regularly used in HIMSCORP's records management
business. The Registrant intends to use the acquired property and equipment in
the operation of its records management business.

Allegiance Business Archives, Ltd.

On October 1, 1997, as previously reported on the Form 8-K dated October 16,
1997, Iron Mountain Records Management, Inc. ("IMRM"), a wholly owned subsidiary
of the Registrant, acquired all of the outstanding capital stock of Allegiance
Business Archives, Ltd. ("Allegiance"), a New Jersey Corporation, for $8.8
million in cash, pursuant to a Stock Purchase and Sale Agreement dated July 29,
1997 among IMRM and the Stockholders of Allegiance Business Archives, Ltd.

The cash consideration was financed primarily by borrowings under the
Registrant's $250 million revolving credit facility (the "Credit Facility")
dated September 29, 1997, as amended, among the Registrant, various financial
institutions and The Chase Manhattan Bank, as administrative agent for such
lenders.

The assets acquired by the Registrant include primarily accounts receivable,
office equipment, furniture and fixtures, motor vehicles, racking and shelving
and intangible personal property regularly used in Allegiance's records
management business. The Registrant intends to use the acquired property and
equipment in the operation of its records management business.

Records Retention/FileSafe

On October 2, 1997, as previously reported on the Form 8-K dated October 16,
1997, IMRM purchased certain assets, including real property, and assumed
certain liabilities of Records Retention/FileSafe ("FileSafe"), a California
limited partnership, for $44.6 million in cash and assumed debt pursuant to an
Asset Purchase and Sale Agreement dated August 20, 1997, among IMRM and
FileSafe.


                                       2
<PAGE>

The cash consideration was financed primarily by borrowings under the Credit
Facility.

The assets acquired by the Registrant include primarily real property, accounts
receivable, office equipment, furniture and fixtures, motor vehicles, racking
and shelving and intangible personal property regularly used in FileSafe's
records management business. The Registrant intends to use the acquired property
and equipment in the operation of its records management business.

Safesite Records Management Corporation

As previously reported on a Form 8-K/A dated August 26, 1997, Safesite Records
Management Corporation ("Safesite"), a Delaware corporation, merged with and
into Iron Mountain/Safesite, Inc., a wholly owned subsidiary of the Registrant,
effective June 12, 1997, pursuant to an Agreement and Plan of Merger dated
February 19, 1997, as amended, among the Registrant, Iron Mountain/Safesite,
Inc. and Safesite. In addition, wholly owned subsidiaries of the Registrant also
acquired certain real property from a trust for the benefit of the controlling
stockholders of Safesite.

The total consideration paid by the Registrant, including transaction costs, was
$70.6 million. The consideration consisted of 1.8 million shares of Common Stock
and options to purchase Common Stock valued at $53.6 million and cash of $17.0
million financed primarily by borrowings under the Credit Facility.

Valuation of Common Stock

The Company has issued shares of Common Stock in connection with certain recent
acquisitions including HIMSCORP and Safesite and will record such shares for
financial reporting purposes at fair value. Because under the terms of the
relevant acquisition agreements a portion of such shares are subject to resale
restrictions, the Company is in the process of obtaining appraisals to determine
the fair value of such shares. Pending the appraisals, the Company initially
recorded the value of such shares based upon their market price at the time of
closing. The Company anticipates that the appraised value of the restricted
shares will be less than the initially recorded value for accounting purposes
and expects to record corresponding decreases in equity, goodwill and goodwill
amortization.

                           IRON MOUNTAIN INCORPORATED
         UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


The following Unaudited Pro Forma Condensed Consolidated Balance Sheet has been
prepared based on the unaudited historical condensed consolidated balance sheet
of the Registrant as of June 30, 1997 and the unaudited historical condensed
consolidated balance sheets as of June 30, 1997 of Allegiance, FileSafe and
HIMSCORP (together with related real estate transactions, the "Current
Acquisitions") and gives effect to the Current Acquisitions as if each had
occurred as of June 30, 1997. The following Unaudited Pro Forma Condensed
Consolidated Statements of Operations for the six months ended June 30, 1997 and
for the year ended December 31, 1996 give effect to the Current Acquisitions and
to the acquisition of Safesite (together with related real estate transactions,
the "Previous Acquisition") as if each had occurred as of January 1, 1996.
However, the aforementioned statements of operations do not include results of
operations prior to the date of acquisition, or pro forma adjustments, for
acquisitions completed by HIMSCORP in 1996 and 1997. Pro Forma adjustments are
described in the accompanying notes.

The Unaudited Pro Forma Condensed Consolidated Statements of Operations are not
necessarily indicative of the actual results of operations that would have been
reported had the Current Acquisitions and the Previous Acquisition been
consummated as of January 1, 1996, nor do they purport to indicate the results
of future operations of the Registrant. Furthermore, the pro forma results do
not give effect to all cost savings or incremental costs which may occur as a
result of the integration and consolidation of the Current Acquisitions and the
Previous Acquisition. In the opinion of management, all adjustments necessary to
present fairly such pro forma financial statements have been made.

All of the acquisitions and related real estate transactions have been accounted
for using the purchase method of accounting.

     (a)     The Company, acting through its Board of Directors, shall, in

Merger and the Transactions.  Acquiror shall take all additional actions as 
sole stockholder of Acquiror Merger Subsidiary necessary to adopt and approve 
and effectuate the provisions of this Agreement, the Merger and the 
Transactions. 

     Section 1.3. Closing. Unless this Agreement shall have been terminated
pursuant to Section 7.1 hereof and the Merger and the Transactions shall have

consummated by filing a certificate of merger with the Secretary of State of the
State of Delaware, and by making any related filings required under the DGCL.
The Merger shall become effective at such time (but not prior to the Closing
Date) as such certificate is



                                       2
<PAGE>

duly filed with the Secretary of State of the State of Delaware, or at such

                                   ARTICLE 2.

              CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES;
                            PAYMENT OF INDEBTEDNESS

     Section 2.1. Conversion of Securities. At the Effective Time, by virtue of
the Merger and without any action on the part of Acquiror Merger Subsidiary, the
Company or the holders of any of the following securities:

     (a)     Each share of Class A Common Stock, par value $.01 per share, of 
the Company (the "Class A Company Stock") issued and outstanding immediately 
prior to the Effective Time (other than any shares of Class A Company Stock to 
be cancelled pursuant to Section 2.1(b) and any Dissenting Shares of Class A 
Company Common Stock), shall be converted into the right to receive, subject 
to Section 5.3(a) hereof and the indemnification provisions of Article 8 
hereof, (i) that number equal to the Class A Stock Conversion Number of fully 
paid and nonassessable shares of Acquiror Stock (the "Class A Stock Merger 
Consideration") and (ii) cash in an amount equal to the Class A Cash 
Conversion Number (the "Class A Cash Merger Consideration"), and each share of 
Class B Common Stock, par value $.01 per share, of the Company (the "Class B 
Company Stock") 



                                       3
<PAGE>

issued and outstanding immediately prior to the Effective Time (other than any
shares of Class B Company Stock to be cancelled pursuant to Section 2.1(b) and
any Dissenting Shares of Class B Company Stock), shall be converted into the
right to receive, subject to Section 5.3(a) hereof and the indemnification
provisions of Article 8 hereof, (i) that number equal to the Class B Stock
Conversion Number of fully paid and nonassessable shares of Acquiror Stock (the
"Class B Stock Merger Consideration") and (ii) cash in an amount equal to the
Class B Cash Conversion Number (the "Class B Cash Merger Consideration"). At the
Effective Time, all shares of Company Stock (the "Shares") shall no longer be
outstanding and shall automatically be cancelled and retired and shall cease to
exist, and certificates previously evidencing any such Shares (each, a
"Certificate") shall thereafter represent the right to receive, upon the
surrender of such Certificate in accordance with the provisions of Section 2.2,
but subject to the indemnification provisions of Article 8 hereof, the Stock
Merger Consideration and Cash Merger Consideration attributable to the number
and class of Shares represented by such Certificate, and a holder of more than
one Certificate shall have the right to receive the Stock Merger Consideration
and Cash Merger Consideration attributable to the number and class of Shares
represented by all such Certificates (the "Exchange Merger Consideration"). The
holders of such Certificates previously evidencing such Shares outstanding
immediately prior to the Effective Time shall cease to have any rights with
respect to such Shares except as otherwise provided herein or by Applicable Law.
Notwithstanding anything to the contrary herein, the Stock Merger Consideration
to be received by any Stockholder prior to the termination of the Escrow
Indemnity Period shall be adjusted to give full effect to the indemnification
provisions in Article 8 hereof.

     (b)     Each Share held in the treasury of the Company and each Share 
owned by Acquiror or any direct or indirect Subsidiary of Acquiror immediately 
prior to the Effective Time shall automatically be cancelled and extinguished 
without any conversion thereof and no payment shall be made with respect 
thereto.

     (c)     Each share of common stock of Acquiror Merger Subsidiary 
outstanding immediately prior to the Effective Time shall continue to be 
outstanding and shall constitute the only outstanding shares of capital stock 
of the Surviving Corporation.

     (d)     In lieu of issuing fractional shares, Acquiror shall convert a 
holder's right to receive shares of Acquiror Stock pursuant to Section 2.1(a) 
into a right to receive the highest whole number of shares of Acquiror Stock 
constituting the non-cash portion of the Exchange Merger Consideration (after 
taking into account the shares of Acquiror Stock to be held in escrow pursuant 
to Article 8 hereof) plus cash equal to the fraction of a share of Acquiror 
Stock to which the holder would otherwise be entitled multiplied by the 
Determination Price, and the Exchange Merger Consideration to which a holder 
is entitled shall be deemed to be such number of shares of Acquiror Stock plus 
such cash in lieu of fractional shares plus the cash portion of the Exchange 
Merger Consideration.  In addition, upon distribution to Stockholders of any 
portion of the Escrow Indemnity Funds, Acquiror shall deliver to each such 
Stockholder the highest whole number of shares of Acquiror Stock to which such 
Stockholder is entitled plus cash equal to the fraction of a share of Acquiror 
Stock to which the holder would otherwise be entitled multiplied by the Market 
Price.  For purposes of carrying out the intent of this Section 2.1(d), 
Acquiror may aggregate Certificates so that fractional 




                                       4
<PAGE>

shares of Acquiror Stock due in exchange for multiple Certificates may be
combined to yield a number of whole shares thereof plus a single fraction.
   
     Section 2.2. Exchange of Certificates; Exchange Agent and Exchange
Procedures.

     (a)     As soon as reasonably practicable after the Effective Time (it 
being understood that Acquiror shall use reasonable best efforts to deposit 
the Cash Merger Consideration with the Exchange Agent on the Closing Date), 
Acquiror shall deposit or cause to be deposited with a bank or trust company 
designated by Acquiror (the "Exchange Agent"), for the benefit of the holders 
of Shares (other than Dissenting Shares), for exchange in accordance with this 
Article, through the Exchange Agent, (i) cash (by wire transfer of federal 
funds pursuant to instructions reasonably satisfactory to the Exchange Agent) 
in an amount equal to the sum of (a) the Class A Cash Merger Consideration 
multiplied by the number of all Shares of Class A Company Stock issued and 
outstanding immediately prior to the Effective Time (other than Shares of 
Class A Company Stock to be cancelled pursuant to Section 2.1(b) and any 
Dissenting Shares of Class A Company Stock) (said number of Shares less said 
Shares to be cancelled and less said Dissenting Shares hereafter to be 
referred to as the "Net Class A Shares"), and (b) the Class B Cash Merger 
Consideration multiplied by the number of all Shares of Class B Company Stock 
issued and outstanding immediately prior to the Effective Time (other than 
Shares of Class B Company Stock to be cancelled pursuant to Section 2.1(b) and 
any Dissenting Shares of Class B Company Stock) (said number of Shares less 
said Shares to be cancelled and less said Dissenting Shares hereafter to be 
referred to as the "Net Class B Shares"), and (ii) the sum of (a) the Class A 
Stock Merger Consideration multiplied by the Net Class A Shares, and (b) the 
Class B Stock Merger Consideration multiplied by the Net Class B Shares, (x) 
less the number of shares of Acquiror Stock constituting the Escrow Indemnity 
Funds and (y) plus cash in an amount sufficient to make payment for fractional 
shares, in exchange for all of the outstanding Shares (collectively, the 
"Exchange Fund").  Subject to Article 8 hereof, the Exchange Agent shall, 
pursuant to irrevocable instructions from Acquiror, deliver the Exchange 
Merger Consideration to be issued pursuant to Section 2.1(a) out of the 
Exchange Fund to holders of Shares upon transmittal of Certificates for 
exchange as provided therein and in Section 2.2(b).  The Exchange Fund shall 
not be used for any other purpose.  Any interest, dividends or other income 
earned by the Exchange Fund shall be for the account of Acquiror.

     (b)     As soon as reasonably practicable after the Effective Time, 
Acquiror will instruct the Exchange Agent to issue (pursuant to instructions 
from each holder of record reasonably satisfactory to Acquiror and the 
Exchange Agent, and otherwise by mail to the most recent address of such 
holder as shown on the Company's books and records) to such holder of a 
Certificate or Certificates which immediately prior to the Effective Time 
evidenced outstanding Shares (other than Shares to be cancelled pursuant to 
Section 2.1(b) and any Dissenting Shares),  a letter of transmittal (which 
shall specify that delivery shall be effected, and risk of loss and title to 
the Certificates shall pass, only upon proper delivery of the Certificates to 
the Exchange Agent and shall be in such form and have such other provisions as 
Acquiror and the Company may reasonably specify) and  instructions to effect 
the surrender of the Certificates in exchange for the Exchange Merger 
Consideration.  Upon surrender of a Certificate for cancellation to the 
Exchange Agent or to such other agent or agents as may be appointed by 
Acquiror together with such letter of transmittal, duly executed, and such 
other 



                                       5
<PAGE>

customary documents as may be reasonably required pursuant to such instructions
(collectively, the "Transmittal Documents"), the holder of such Certificate
shall be entitled to receive in exchange therefor the Exchange Merger
Consideration which such holder has the right to receive, subject to Article 8
hereof, pursuant to Sections 2.1(a) and 2.1(d) hereof, and the Certificate so
surrendered shall forthwith be cancelled. In the event of a transfer of
ownership of Shares which is not registered in the transfer records of the
Company, the Exchange Merger Consideration may be issued and paid in accordance
with this Article to a transferee if the Certificate evidencing such Shares is
presented to the Exchange Agent, accompanied by all documents reasonably
required to evidence and effect such transfer and by evidence that any
applicable stock transfer taxes have been paid. The Exchange Merger
Consideration will be delivered by the Exchange Agent promptly following
surrender of a Certificate and the related Transmittal Documents, and cash
payments for fractional shares and the cash portion of the Exchange Merger
Consideration may be made by check (or, pursuant to instructions reasonably
satisfactory to the Exchange Agent, by wire transfer). No interest will be
payable on the Exchange Merger Consideration regardless of any delay in making
payments. Until surrendered as contemplated by this Section, each Certificate
shall be deemed at any time after the Effective Time to evidence only the right
to receive, upon such surrender, the Exchange Merger Consideration, without
interest. Notwithstanding the foregoing, any Stockholder may, prior to the
Effective Time, request a letter of transmittal from Acquiror, and, if proper
delivery of all applicable Transmittal Documents is made to the Exchange Agent
prior to the Effective Time, the Exchange Agent shall deliver to the holder
thereof by wire transfer of immediately available funds in accordance with
instructions contained in such Stockholder's Transmittal Documents as promptly
as is practicable after the Exchange Agent's receipt from Acquiror of the Cash
Merger Consideration the full amount of Cash Merger Consideration to which such
Stockholder is entitled.

     (c)     In the event any Certificate shall have been lost, stolen or 
destroyed, upon the making of an affidavit of that fact by the Person claiming 
such Certificate to be lost, stolen or destroyed and subject to such other 
conditions as Acquiror reasonably may impose, the Surviving Corporation shall 
issue in exchange for such lost, stolen or destroyed Certificate the Exchange 
Merger Consideration deliverable in respect thereof as determined in 
accordance with Sections 2.1(a) and 2.1(d), subject to Article 8 hereof.  
Acquiror may, in its discretion and as a condition precedent to authorizing 
the issuance thereof by the Surviving Corporation, require the owner of such 
lost, stolen or destroyed Certificate to provide a bond or other surety to 
Acquiror and the Surviving Corporation in such sum as Acquiror may reasonably 
direct as indemnity against any claim that may be made against Acquiror or the 
Surviving Corporation (and their Affiliates) with respect to the Certificate 
alleged to have been lost, stolen or destroyed.

     (d)     Any portion of the Exchange Fund which remains undistributed to 
the holders of the Company Stock for ninety (90) days after the Effective Time 
shall be delivered to Acquiror upon demand by Acquiror, and any holders of 
Certificates who have not theretofore complied with this Article shall 
thereafter look only to Acquiror for the Exchange Merger Consideration to 
which they are entitled pursuant to this Article.

     (e)     None of Acquiror, Acquiror Merger Subsidiary, the Company or the 
Surviving Corporation shall be liable to any holder of Shares for any shares 
of Acquiror Stock or cash from the 



                                       6
<PAGE>

Exchange Fund delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

     (f)     Each of Acquiror, the Surviving Corporation and the Exchange 
Agent shall be entitled to deduct and withhold from the consideration 
otherwise payable pursuant to this Agreement to any holder of Shares such 
amounts as Acquiror, the Surviving Corporation or the Exchange Agent is 
required to deduct and withhold with respect to the making of such payment 
under the Code, or any provision of federal, state, local or foreign tax law.  
To the extent that amounts are so withheld by Acquiror, the Surviving 
Corporation or the Exchange Agent, such withheld amounts shall be treated for 
all purposes of this Agreement as having been paid to the holder of the Shares 
in respect of which such deduction and withholding was made by Acquiror,  the 
Surviving Corporation or the Exchange Agent.

     Section 2.3. Stock Transfer Books. At the Effective Time, the stock
transfer books of the Company shall be closed, and there shall be no further
registration of transfers of Shares thereafter on the records of the Company
other than to Acquiror. On or after the Effective Time, any Certificate
presented to the Exchange Agent or the Surviving Corporation shall be converted
into the Exchange Merger Consideration.

     Section 2.4. Dissenting Shares.

     (a)     Notwithstanding any other provision of this Agreement to the 
contrary, Shares that are outstanding immediately prior to the Effective Time 
and which are held by Stockholders who shall have not voted in favor of the 
Merger or consented thereto in writing and who shall be entitled to and shall 
have demanded properly in writing appraisal for such Shares in accordance with 
the DGCL, and who shall not have withdrawn such demand or otherwise have 
forfeited appraisal rights (collectively, the "Dissenting Shares") shall not 
be converted into or represent the right to receive the Merger Consideration.  
Such Stockholders shall be entitled to receive payment of the appraised value 
of such Shares held by them in accordance with the provisions of the DGCL, 
except that all Dissenting Shares held by Stockholders who shall have failed 
to perfect or who effectively shall have withdrawn, forfeited or lost their 
rights to appraisal of such Shares under the DGCL shall thereupon be deemed to 
have been converted into and to have become exchangeable for, as of the 
Effective Time, the right to receive, without any interest thereon, the 
Exchange Merger Consideration attributable to such Shares, upon surrender, in 
the manner provided in Section 2.2, of the Certificate or Certificates that 
formerly evidenced such Shares.

     (b)     The Company shall give Acquiror prompt notice of any demands for 
appraisal received by it, withdrawals of such demands, and any other 
instruments served pursuant to the DGCL and received by the Company and 
relating thereto.  The Company and Acquiror shall jointly direct all 
negotiations and proceedings with respect to demands for appraisal under 
Applicable Law.  The Company shall not, except with the prior written consent 
of Acquiror, make any payment with respect to any demands for appraisal, or 
offer to settle, or settle, any such demands.

     Section 2.5. Payment of Indebtedness. Contemporaneously with the Effective
Time, Acquiror shall, or shall cause the Surviving Corporation to, pay and
satisfy in full by wire transfer 



                                       7
<PAGE>

of immediately available funds, the unpaid balance (principal and interest) of
the Company's and its Subsidiaries' Indebtedness described in the Indebtedness
Schedule attached hereto; provided, however, that neither Acquiror nor the
Surviving Corporation shall be required to pay in full at the Effective Time (i)
the Indebtedness under the subordinated promissory notes due January 2, 2002
issued to former stockholders of JAD Interests, Inc. in connection with its
merger into HIMSCORP of San Diego, Inc., (ii) any Indebtedness listed on the
Indebtedness Schedule in respect of capitalized leases or (iii) any other
Indebtedness which the Indebtedness Schedule indicates is not to be so paid in
full.


                                   ARTICLE 3.

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company hereby represents and warrants to Acquiror and Acquiror 
Merger Subsidiary as follows:

     Section 3.1. Organization and Business; Power and Authority; Effect of
Transaction.

     (a)     The Company: 

          (i) is a corporation duly organized, validly existing and in good
     standing under the laws of the State of Delaware,

          (ii) has all requisite power and corporate authority to own or hold

     Disclosure Schedule, has in full force and effect all Governmental
     Authorizations and Private Authorizations and has made all Governmental
     Filings, to the extent required for such ownership and lease of its
     property and conduct of its business, and

          (iii) is, to the Company's knowledge, duly qualified and authorized to
     do business and is in good standing as a foreign corporation in each
     jurisdiction (a true and correct list of which is set forth in Section
     3.1(a) of the Disclosure Schedule) in which the character of its property
     or the nature of its business or operations requires such qualification or
     authorization, except to the extent the failure to so qualify or to
     maintain such authorizations would not have an Adverse Effect.

     (b)     The Company has all requisite power and corporate authority and 
has in full force and effect all Governmental Authorizations and Private 
Authorizations in order to enable it to execute and deliver, and to perform 
its obligations under, this Agreement and each Collateral Document executed or 
required to be executed by it pursuant hereto or thereto and to consummate the 
Merger and the Transactions, and the execution, delivery and performance of

                                       8
<PAGE>



Collateral Document executed or required to be executed pursuant hereto or
thereto or to consummate the Merger and the Transactions, when executed and
delivered by the Company or an Affiliate of the Company will constitute, legal,
valid and binding obligations of the Company or such Affiliate, enforceable in
accordance with their respective terms, except as such enforceability may be
subject to bankruptcy, moratorium, insolvency, reorganization, arrangement,
voidable preference, fraudulent conveyance and other similar laws relating to or
affecting the rights of creditors and except as the same may be subject to the
effect of general principles of equity (the "Enforceability Exceptions"). The
affirmative vote or action by written consent of the holders of a majority of
the outstanding Shares (which requisite vote has been obtained by the Principal
Stockholder's execution and delivery of a written consent on the date hereof) is
the only vote of the holders of any class or series of the capital stock of the
Company necessary to approve this Agreement, the Merger and the Transactions
under Applicable Law and the Company's Organic Documents. The provisions of
Section 203 of the DGCL will not apply to this Agreement, the Merger or the
Transactions.

     (c)     Except as set forth in Section 3.1(c) of the Disclosure Schedule, 
neither the execution and delivery of this Agreement or any Collateral 
Document executed or required to be executed pursuant hereto or thereto, nor 
the consummation of the Transactions, nor compliance with the terms, 
conditions and provisions hereof or thereof by the Company, any Company 
Subsidiary or the Principal Stockholder:

          (i) will conflict with, or result in a breach or violation of, or
     constitute a default under, any Applicable Law on the part of the Company
     or any Company Subsidiary or will conflict with, or result in a breach or
     violation of, or constitute a default under, or permit the acceleration of
     any obligation or liability in, or but for any requirement of giving of
     notice or passage of time or both would constitute such a conflict with,
     breach or violation of, or default under, or permit any such acceleration
     in, any Contractual Obligation of the Company or any Company Subsidiary,

          (ii) will result in or permit the creation or imposition of any Lien
     upon any property now owned or leased by the Company, any Company
     Subsidiary or any such other party, or

          (iii) will require any Governmental Authorization or Governmental
     Filing or Private Authorization, except for the certificate of merger and
     related filings under the DGCL in connection with the Merger and the
     Transactions and except pursuant to the HSR Act.

     (d)     The Company does not have any Subsidiaries other than those set 
forth on Section 3.1(d) of the Disclosure Schedule, each of which is directly 
or indirectly wholly owned, is a corporation which is duly organized, validly 
existing and in good standing under the laws of the respective state of 
incorporation set forth opposite its name on Section 3.1(d) of the Disclosure 
Schedule, and is duly qualified and in good standing as a foreign corporation 
in each other jurisdiction (as shown in Section 3.1(d) of the Disclosure 
Schedule) in which the character of its property or the nature of its business 
or operations requires such qualification or authorization (except to the extent
 the failure to so qualify would not, individually or in the aggregate, have

financial statements forming part of the Financial Statements, except to the
extent specifically described in Section 3.3 of the Disclosure Schedule, there
has been no Adverse Change in the Company. To the Company's knowledge, there is

whole, or the ability of the Company to perform any of the obligations set forth
in this Agreement or any Collateral Document executed or required to be executed
pursuant hereto or thereto except for changes in general economic conditions or
the industry in general and to the extent set forth in Section 3.3 of the
Disclosure Schedule.

     Section 3.4. Liabilities. At the date of the most recent balance sheet
forming part of the Financial Statements, neither the Company nor any Company
Subsidiary had any obligations or liabilities, past, present or deferred,
accrued or unaccrued, fixed, absolute, contingent or other (including, without
limitation, any contingent payments or "earnouts" owing under any Acquisition
Agreement), except as disclosed in such balance sheet, or the notes thereto, and
since such date neither the Company nor any Company Subsidiary has incurred any
such obligations or liabilities, other than obligations and liabilities incurred
in the ordinary course of business consistent with past practice of the Company
and the Company Subsidiaries, which do not and, to the Company's knowledge, will
not, in the aggregate, Adversely Affect the Company, except to the extent set

     (a)     The Company and its Subsidiaries do not own any real property.  
To the Company's knowledge, each of the Company and its Subsidiaries has good 
leasehold title with respect to all real property it leases.  Each of the 
Company and its Subsidiaries has good indefeasible and merchantable title to 
all other assets, tangible and intangible, reflected on the most recent 
balance sheet forming part of the Financial Statements, or (excluding leased 
real estate) held by the Company or any Company Subsidiary for use in its 
business if not so reflected, or purported to have been acquired by the 
Company or any Company Subsidiary since such date, except inventory sold or 
depleted, or property, plant and other equipment used up or retired, since 
such date, in each case in the ordinary course of business consistent with 
past practice of the Company and its Subsidiaries, free and clear of all 
Liens, except (i) Liens reflected in the Financial Statements, (ii) Liens for 
current taxes not yet due and payable, (iii) Liens set forth on Section 3.5(a) 
of the Disclosure Schedule, (iv) Liens that will be released prior to the 
Closing Date (and which are listed on Section 3.5(a) of the Disclosure 
Schedule), (v) Permitted Liens, and (vi) such imperfections of title, 
easements, encumbrances and mortgages or other Liens, if any, as are not, 
individually or in the aggregate, substantial in character, amount or extent 
and do not materially detract from the value, or materially interfere with the 
present use, of the property subject thereto or affected thereby, or otherwise 
materially impair business operations.  Each Lease or other occupancy or other 
agreement under which the Company or any 



                                       11
<PAGE>

Company Subsidiary holds real or personal property has been duly authorized,
executed and delivered by the Company or a Company Subsidiary, and, to the
Company's knowledge, by each of the other parties thereto; each such Lease is a
legal, valid and binding obligation of the Company or a Company Subsidiary, and,
to the Company's knowledge, of each other party thereto, enforceable in
accordance with its terms (subject to the Enforceability Exceptions). To the
Company's knowledge, each of the Company and its Subsidiaries has a valid
leasehold interest in and enjoys peaceful and undisturbed possession under all
Leases pursuant to which it holds any real property or tangible personal
property, none of which, to the Company's knowledge, contains any provision
which would impair the Company's or a Company Subsidiary's ability to use such
property as it is currently used by the Company or a Company Subsidiary, except
as described in Section 3.5(a) of the Disclosure Schedule. To the Company's
knowledge, (i) all of such Leases are valid and subsisting and in full force and
effect and (ii) except as set forth in Section 3.5(a) of the Disclosure
Schedule, none of the Company, its Subsidiaries or any other party thereto is in
default in the performance, observance or fulfillment of any obligation,
covenant or condition contained in any such Lease.

     (b)     Section 3.5(b) of the Disclosure Schedule contains a true, 
correct and complete address and general description of all real estate leased 
by the Company or any Company Subsidiary.

     (c)     To the Company's knowledge, except as set forth in Section 3.5(c) 
of the Disclosure Schedule, all real property leased by the Company or any 
Company Subsidiary conforms to and complies with, except as in the aggregate 
would not result in an Adverse Effect on the Company, all applicable title 
covenants, conditions, restrictions and reservations and all Environmental 
Laws and all applicable zoning, wetlands, land use and other Applicable Laws.

     Section 3.6. Compliance with Private Authorizations. Section 3.6 of
the Disclosure Schedule sets forth, to the Company's knowledge, a true, 
correct and complete list and description of each Private Authorization which 
individually is material to the Company and its Subsidiaries, all of which are 
in full force and effect, except as set forth in Section 3.6 of the Disclosure 
Schedule.  To the Company's knowledge, each of the Company and its 
Subsidiaries has obtained all Private Authorizations which are necessary for 
the ownership by the Company or such Company Subsidiary of its properties and 
the conduct of its business as now conducted or which, if not obtained and 
maintained, could reasonably be expected to, singly or in the aggregate, 
Adversely Affect the Company.  To the Company's knowledge, except as set forth 
in Section 3.6 of the Disclosure Schedule, (i) neither the Company nor any 
Company Subsidiary is in breach or violation of, or is in default in the 
performance, observance or fulfillment of, any Private Authorization, and (ii) 
no Event exists or has occurred, which constitutes, or but for any requirement 
of giving of notice or passage of time or both would constitute, such a 
breach, violation or default, under any Contractual or Private Authorization, 
except for such defaults, breaches or violations as do not and, to the 
Company's knowledge, will not in the aggregate have any Adverse Effect on the 
Company or the ability of the Company to perform any of the obligations set 
forth in this Agreement or any Collateral Document executed or required to be 
executed pursuant hereto or thereto or to consummate the Merger and the 
Transactions.  No material Private Authorization is the subject of any pending 
or, to the Company's knowledge, threatened attack, revocation or termination.

     Section 3.7. Compliance with Governmental Authorizations and
Applicable Law.

     (a)     Section 3.7(a)  of the Disclosure Schedule contains a description 
of:

          (i) all Legal Actions which are pending in which the Company or any
     Company Subsidiary is a party, or to which the business, operations or
     properties of the Company or any Company Subsidiary are subject or, to the
     Company's knowledge, which are threatened or contemplated against, the
     Company or any Company Subsidiary or any of their respective business,
     operations or properties, which in the case of such threatened or
     contemplated Legal Actions, individually or in the aggregate, if determined
     against the Company or any Company Subsidiary would reasonably be expected
     to have an Adverse Effect on the Company; and
 
          (ii) to the Company's knowledge, each material Governmental
     Authorization to which the Company or any Company Subsidiary is subject and
     which relates to the business, operations, properties, prospects, condition
     (financial or other), or results of operations of the Company and its
     Subsidiaries, and, except as set forth in Section 3.7(a)(ii) of the
     Disclosure Schedule, each Governmental Authorization known to the Company
     to which the Company or any Company Subsidiary is subject and which relates
     to the business, operations, properties, prospects, condition (financial or
     other), or results of operations of the Company and its Subsidiaries is in
     full force and effect.

     (b)     To the Company's knowledge, the Company and its Subsidiaries have 
obtained all Governmental Authorizations which are necessary for the ownership 
or use of their respective properties and the conduct of their respective 
business as now conducted by the Company or any Company Subsidiary or which, 
if not obtained and maintained, could singly or in the aggregate, have any 
Adverse Effect on the Company.  No material Governmental Authorization is the 
subject of any pending or, to the Company's knowledge, threatened attack, 
revocation or termination.  To the Company's knowledge, (i) neither the 
Company nor any Company Subsidiary is in material breach or violation of, or 
in default in the performance, observance or fulfillment of, any Governmental 
Authorization or any Applicable Law, and (ii) no Event exists or has occurred, 
which constitutes, or but for any requirement of giving of notice or passage 
of time or both would constitute, such a breach, violation or default, under 
any Governmental Authorization or any Applicable Law, except for such 
breaches, violations or defaults as do not and, to the Company's knowledge, 
will not have in the aggregate any Adverse Effect on the Company.

     (c)     The matters, if any, referred to in Section 3.7(a) of  the 
Disclosure Schedule, if adversely determined against the Company or any 
Company Subsidiary, will not Adversely Affect the Company, except to the 
extent set forth in the Disclosure Schedule, or the ability of the Company to 
perform its obligations under this Agreement or any Collateral Documents 
executed or required to be executed pursuant hereto or thereto or to 
consummate the Merger and the Transactions.

     Section 3.8. Intangible Assets. Section 3.8 of the Disclosure
Schedule sets forth a true and accurate description of all Intangible Assets 
held or used by the Company and its Subsidiaries, including without limitation 
the nature of the Company's and its Subsidiaries' interest in each and 




                                       13
<PAGE>

the extent to which the same have been duly registered in the offices as
indicated therein. To the Company's knowledge, each of the Company and its
Subsidiaries owns or possesses or otherwise has the right to use all Intangible
Assets necessary for the conduct of its business, except where the failure to so
own, possess or have the right to use would not, insofar as can reasonably be
foreseen, individually or in the aggregate, have an Adverse Effect on the
Company. To the Company's knowledge, except as set forth in Section 3.8 of the
Disclosure Schedule, no authorizations or intangible assets (except the
Intangible Assets so set forth) are required for each of the Company and its
Subsidiaries to conduct its business. Except as set forth in Section 3.8 of the
Disclosure Schedule, the Company possesses all proprietary rights in and to the
principal software used in operating and conducting its business and no other
Person has any rights therein or with respect thereto.

     Section 3.9. Related Transactions. Section 3.9 of the Disclosure
Schedule sets forth a true, correct and complete (in all material respects) 
description of any Contractual Obligation or transaction, whether now existing 
or existing during the period covered by the most recent audited Financial 
Statements, between the Company or any Company Subsidiary and any Affiliate 
thereof (other than (a) any transaction between the Company and any Company 
Subsidiary or between Company Subsidiaries and (b) reasonable compensation for 
services as officers, directors and employees and reimbursement for 
out-of-pocket expenses reasonably incurred in support of the Company's and its 
Subsidiaries' business), including without limitation any providing for the 
furnishing of services to or by, providing for rental of property, real, 
personal or mixed, to or from, or providing for the lending or borrowing of 
money to or from or otherwise requiring payments to or from, any such 
Affiliate.

     Section 3.10. Insurance.

policies maintained by the Company or any Company Subsidiary and includes the 
insurers' names, policy numbers, expiration dates, risks insured against, 
amounts of coverage, the annual premiums, exclusions, deductibles and 
self-insured retention and describes in reasonable detail any retrospective 
rating plan, fronting arrangement or any other self-insurance or risk assumption
 agreed to by the Company or any Company Subsidiary or imposed upon the 
Company or any Company Subsidiary by any such insurers, as well as any 
self-insurance program that is in effect.

     (b)     To the Company's knowledge, except as set forth in Section 
3.10(b) of the Disclosure Schedule, neither the Company nor any Company 
Subsidiary is in breach or violation of or in default under any such policy, 
and all premiums due thereon have been paid, and each such policy or a 
comparable replacement policy will continue to be in force and effect up to 
and including the Closing Date.
 
     Section 3.11. Tax Matters.

     (a)     Each of the Company and each Company Subsidiary has in accordance 
with all Applicable Laws filed all Tax Returns which are required to be filed, 
and has paid, or made adequate provision for the payment of, all Taxes which 
have or may become due and payable pursuant to said 




                                       14
<PAGE>

Returns and all other governmental charges and assessments received to date. The
Tax Returns of the Company and each Company Subsidiary have been prepared in
accordance with all Applicable Laws and generally accepted principles applicable
to taxation consistently applied. All Taxes which the Company and each Company
Subsidiary are required by law to withhold and collect have been duly withheld
and collected, and have been paid over, in a timely manner, to the proper
Authorities to the extent due and payable. Neither the Company nor any Company
Subsidiary has executed any waiver to extend, or otherwise taken or failed to
take any action that would have the effect of extending, the applicable statute
of limitations in respect of any Tax liabilities of the Company or any Company
Subsidiary for the fiscal years prior to and including the most recent fiscal
year. Adequate provision has been made on the most recent balance sheet forming
part of the Financial Statements for all Taxes of any kind, whether disputed or
not, and whether past or current, fixed, contingent or absolute, and to the
knowledge of the Company there are no transactions or matters or any basis which
might or could result in additional Taxes of any nature to the Company or any
Company Subsidiary for which an adequate reserve has not been provided on such
balance sheet. Neither the Company nor any Company Subsidiary is a "consenting
corporation" within the meaning of Section 341(f) of the Code. Each of the
Company and each Company Subsidiary has at all times been taxable as a
Subchapter C corporation under the Code, except as otherwise set forth in
Section 3.11(a) of the Disclosure Schedule. Neither the Company nor any Company
Subsidiary has ever been a member of any consolidated group (other than
exclusively with the Company and its Subsidiaries) for Tax purposes, except as
set forth in Section 3.11(a) of the Disclosure Schedule.

     (b)     Each of the Company and each Company Subsidiary has paid all 
Taxes which have become due pursuant to its Returns and has paid all 
installments (to the extent required to avoid material underpayment penalties) 
of estimated Taxes due and payable.  

     (c)     From the end of its most recent fiscal year to the date hereof, 
neither the Company nor any Company Subsidiary has made any payment on account 
of any Taxes except regular payments required in the ordinary course of 
business, consistent with prior practice, with respect to current operations 
or property presently owned.

     (d)     The information shown on the Federal income Tax Returns of the 
Company and its Subsidiaries (true, correct and complete copies of which have 
been furnished by the Company to Acquiror) is true, correct and complete in 
all material respects and fairly and accurately reflects the information 
purported to be shown.  Federal and state income Tax Returns of the Company 
and its Subsidiaries have been examined by the IRS or applicable state 
Authority through the taxable periods set forth in Section 3.11(d) of the 
Disclosure Schedule, and neither the Company nor any Company Subsidiary has 
been notified in writing regarding any pending examination, except as shown in 
Section 3.11(d) of the Disclosure Schedule.

     (e)     Neither the Company nor any Company Subsidiary is a party to any 
tax sharing agreement or arrangement.

     (f)     Neither the Company nor any Company Subsidiary is, and since the 
date of its incorporation has not been, a "United States real property holding 
corporation" as defined in Section 897 of the Code.

approval of any Authority or otherwise, Acquiror shall not be required to
divest, abandon, license or take similar action with respect to any assets
(tangible or intangible) of it or any of its Subsidiaries (including, without

     (b)     The Company will use its reasonable best efforts on or prior to 
the Closing Date to obtain the satisfaction of the conditions specified in 
Sections 6.1 and 6.2.  Each of Acquiror and Acquiror Merger Subsidiary will

statement or other public filing of Acquiror under the Securities Act and the 
Exchange Act, and any other offering circular or document used by Acquiror in 
any other offering, whether public or private, and (ii) shall use its best 
efforts to cause the Company's independent accountants to cooperate with 
Acquiror in connection with the foregoing (including, without limitation, 
using best efforts to cause such independent accountants to deliver so-called 
"comfort letters," written consents and representation letters relating to the 
foregoing); provided, however, that Acquiror shall reimburse the Company for 
its reasonable out-of-pocket expenses incurred in connection with its 
compliance with this Section 5.2(e) (which reimbursement obligation will 
survive termination of this Agreement pursuant to Section 7.1 (other than a 
termination pursuant to Section 7.1(d)(ii)(B)(I) for the Company's breach of 
this Section 5.2(e) and other than a termination pursuant to Section

the use of such audited financial statements in any such registration 
statement, document or circular and (ii) execute and deliver, and cause its

countersign each such Investment Agreement and Noncompetition and 
Nonsolicitation Agreement on or prior to the Closing Date.  Notwithstanding 
anything to the contrary herein, it shall be a condition to a Stockholder's 
right to receive shares of Acquiror Stock pursuant to the Merger that such

that such Person is or was a director or officer of the Company or any Company
Subsidiary and arising out of actions or omissions occurring at or prior to the
Effective Time (including, without limitation, the Merger and the Transactions),
in each case to the fullest extent currently provided under the Company's or
such Subsidiary's Organic Documents (but only to the extent permitted under the
DGCL), and shall pay any expenses in advance of the final disposition of any
such action or proceeding to each such Person to the fullest extent permitted
under the DGCL, upon receipt from the Person to whom expenses are advanced of an
undertaking to repay such advances to the extent required under the DGCL.

condition or agreement to be complied with or satisfied by it hereunder;
provided, however, that the delivery of any notice pursuant to this Section 5.6

Notwithstanding the foregoing, the Company acknowledges and agrees that Acquiror
may, without the prior consent of the Company, issue such press releases or make
such public statements as may be required by

Applicable Law, in which case, to the extent practicable, Acquiror will consult

the Company regarding the nature, extent and form of such press release or
public statement, and, in any event, with prior notice to the Company.

"Qualified Plan").  If a Qualified Plan is terminated in accordance with this 
Section 5.9(b), benefit accruals, including contributions of salary reduction 
contributions, if any, shall cease.  The Company agrees to take no action to 
merge any of its Qualified Plans, transfer the assets of any of its Qualified 
Plans, or terminate any of its Qualified Plans, except as otherwise provided 
in this Section 5.9(b), following the execution of this Agreement without the 
consent of Acquiror.

     Section 5.10.     Certain Actions Concerning Business Combinations.  The 
Company will not apply, and will not take any action resulting in the

the Transactions.

after the Closing Date, except as permitted under Section 368(a)(2)(C) of the

Section 368 of the Code, or unless it first shall have received an opinion of
counsel from Sullivan & Worcester LLP or another law firm of national standing

tax-free nature of the Merger. Acquiror, Acquiror Merger Subsidiary and the

facilitate the provision of the tax opinions described in Sections 6.2(i) and

     continue to be untrue in any material respect, unless such breach or
     untruth is capable of being cured by and will not prevent or delay
     consummation of the Merger by or beyond the Termination Date, and (B)
     either (I) the Company is in breach of this Agreement or any of its

     by underwriters in connection with an underwritten offering of securities
     or by initial purchasers in connection with a private placement of
     securities) relating to the Company's provision, pursuant to and in
     accordance with Section 5.2(e), of consolidated financial statements for
     the Company in connection with any registration statement or other public
     filing of Acquiror under the Securities Act and the Exchange Act, or any

     of the foregoing, or (II) have recommended or resolved to recommend to the
     Stockholders any Other Transaction, or (B) the Company shall have entered
     into or agreed to enter into any Other Transaction.

     Section 7.2. Effect of Termination. Except as provided in Sections 5.1,
5.7, 7.2 and 7.5 and in the provisos in the first sentence of Section 5.2(e), in
the event of the termination of this Agreement pursuant to Section 7.1, this
Agreement shall forthwith become void, there shall be no liability on the part
of any Party, or any of their respective officers or directors, to the other and
all rights and obligations of any Party shall cease; provided, however, that
such termination shall not relieve any Party from liability for the knowing and
willful breach of any of its representations, warranties, covenants or
agreements set forth in this Agreement, or impair the right of the Company, on
the one hand, and Acquiror and Acquiror Merger Subsidiary, on the other hand, to
compel specific performance of the other party of its or their obligations under
this Agreement which survive termination.

     Section 7.3. Amendment. This Agreement may be amended by the Parties by
action taken by or on behalf of the respective Boards of Directors thereof at
any time prior to the Effective Time; provided, however, that, after approval of
this Agreement and the Merger by the Stockholders, no amendment, which under
Applicable Law may not be made without the approval of the Stockholders, may be
made without such approval. This Agreement may not be amended except by an
instrument in writing signed by the Parties hereto.



                                       38
<PAGE>

     Section 7.4. Waiver. At any time prior to the Effective Time, except to the
extent Applicable Law does not permit, either Acquiror and Acquiror Merger
Subsidiary or the Company may extend the time for the performance of any of the
obligations or other acts of the other, subject, however, to the terms and
conditions of Section 7.1, waive any inaccuracies in the representations and
warranties of the other contained herein or in any document delivered pursuant
hereto and waive compliance by the other with any of the agreements, covenants
or conditions contained herein. Any such extension or waiver shall be valid only
if set forth in an agreement in writing signed by the Party or Parties to be
bound thereby.

     Section 7.5. Fees, Expenses and Other Payments. All costs and expenses
incurred in connection with this Agreement, the Merger and the Transactions, and
compliance with Applicable Law and Contractual Obligations as a consequence
hereof and thereof, including, without limitation, filing fees under the HSR
Act, fees and disbursements of counsel, financial advisors and accountants,
incurred by the Parties shall be borne solely and entirely by the Party which
has incurred such costs and expenses (with respect to such Party, its
"Expenses") ; provided, however, that Acquiror shall reimburse the Principal
Stockholder for the filing fee payable in connection with his filing of a
Notification and Report Form under the HSR Act (if such a filing is required) in
connection with his acquisition of shares of Acquiror Stock pursuant to the
Merger. Without limiting the generality of the foregoing, the Company agrees to
pay its and its Subsidiaries' Expenses in full prior to the Effective Time, it
being the understanding of the Parties that none of Acquiror, the Surviving
Corporation or Acquiror Merger Subsidiary shall become liable for any of the
Company's Expenses by virtue of the Merger.

     Section 7.6. Effect of Investigation. The right of any Party to terminate
this Agreement pursuant to Section 7.1 shall remain operative and in full force
and effect regardless of any investigation made by or on behalf of any Party, or
any Person controlling any such party or any of their respective Representatives
whether prior to or after the execution of this Agreement.

               INDEMNIFICATION; COMPANY INDEBTEDNESS CALCULATION

     Section 8.1. Survival. The representations, warranties, covenants and
agreements of the Company contained in or made pursuant to this Agreement or any
Collateral Document shall survive the Closing and shall remain operative and in
full force and effect for a period of one (1) year after the Closing Date (the
"Escrow Indemnity Period"), regardless of any investigation or statement as to
the results thereof made by or on behalf of any Party. No claim for
indemnification may be asserted after the expiration of the Escrow Indemnity
Period. Notwithstanding anything herein to the contrary, any representation,
warranty, covenant and agreement which is the subject of a Claim which is
asserted in writing prior to the expiration of the Escrow Indemnity Period shall
survive with respect to such Claim or any dispute with respect thereto until the
final resolution thereof.



                                       39

     Section 8.2. Escrow; Indemnification. The Parties hereto agree, and by
adopting and approving this Agreement and the Merger, the Stockholders shall
agree, that the Escrow Indemnity Funds will be withheld from the Exchange Merger
Consideration and held in escrow in accordance with the terms of this Article 8
and the Escrow Agreement in order to provide a fund to indemnify Acquiror and
hold Acquiror harmless from and against any and all damages, claims, losses,
expenses, costs, obligations and liabilities, including without limitation
liabilities for all reasonable attorneys', accountants', and experts' fees and
expenses including those incurred to enforce the terms of this Agreement or any
Collateral Document (collectively, "Loss and Expense"), suffered, directly or
indirectly, by Acquiror by reason of, or arising out of:

     (a)     any breach of representation or warranty made by the Company 
pursuant to this Agreement or any Closing Certificate or any failure by the 
Company to perform or fulfill any of its covenants or agreements set forth in 
this Agreement or any Closing Certificate;

     (b)     any Legal Action or other Claim by any third party relating to 
the Company to the extent such Legal Action or other Claim has resulted in a 
breach of representation or warranty by the Company pursuant to this Agreement 
or any Collateral Document; 

     (c)     the Indebtedness, if any, of the Company and its Subsidiaries as 
of the Effective Time exceeding the Company Indebtedness Calculation; 

     (d)     the amount of the Houston Earnout exceeding $300,000; or

     (e)     any Legal Action or other Claim by any individual relating to or 
arising out of (i) the terms, conditions or circumstances of such individual's 
employment (including as a part-time employee or consultant) by the Company or 
any Company Subsidiary prior to the Closing or (ii) the repurchase of Company 
Stock in connection with the termination of such individual's employment by 
the Company or any Company Subsidiary prior to the Closing.
 .     
     The Company hereby appoints, and by adopting and approving this Agreement 
and the Merger, the Stockholders shall appoint, Kent P. Dauten (the "Agent", 
with full and unqualified power to delegate to one or more persons the 
authority granted to him hereunder) to act as his, her or its agent and 
attorney-in-fact, with full power of substitution, to take all actions called 
for by this Article 8 and the Escrow Agreement on his, her or its behalf, in 
accordance with the terms of this Article 8 and the Escrow Agreement.

     Section 8.3. Limitation of Liability; Disposition of Escrow Indemnity
Funds.

     (a)     Notwithstanding the provisions of Section 8.2, after the Closing, 
except as set forth in the following sentence, Acquiror's rights to 
indemnification shall be subject to the following limitations: (i) Acquiror 
shall be entitled to recover its Loss and Expense in respect of any Claim only 
if the Loss and Expense for all Claims exceeds, in the aggregate, $150,000 
(and then only to 



                                       40
<PAGE>

the extent in excess of such $150,000) and (ii) in no event shall the aggregate
amount to be paid to Acquiror exceed the lesser of (x) the Escrow Indemnity
Funds and (y) shares of Acquiror Stock having an aggregate Market Value (valued
for such purpose at the Market Price at which such shares are valued for purpose
of the distribution from the Escrow Indemnity Funds) of Two Million Five Hundred
Thousand Dollars ($2,500,000). The limitations in clause (i) of the first
sentence of this Section 8.3(a) shall not apply to Claims in respect of a breach
by the Company of its representations and warranties in Section 3.12 of this
Agreement or its obligations under Section 5.9(b) or 7.5 of this Agreement or to
Claims pursuant to Section 8.2(c) or (d) or clause (ii) of Section 8.2(e) of
this Agreement.

     (b)     Anything in this Agreement, including without limitation the 
provisions of Sections 8.2 or 8.3(a), to the contrary notwithstanding, the 
exclusive recourse of Acquiror with respect to Claims brought after the 
Effective Time arising out of the transactions contemplated by this Agreement 
shall be the Escrow Indemnity Funds.  On or before the Closing Date, Acquiror, 
the Company and the Agent shall execute and deliver an escrow agreement 
substantially in the form attached hereto as Exhibit 8.3 (the "Escrow 
Agreement").  Any Claims of Acquiror for indemnification to be satisfied out 
of the Escrow Indemnity Funds shall be made in accordance with the terms of 
the Escrow Agreement (it being hereby understood that for purposes of 
determining the number of shares of Acquiror Stock necessary to satisfy such 
Claim, the Market Price of the Acquiror Stock calculated in accordance with 
the terms of the Escrow Agreement shall be used).  At the Effective Time, a 
certificate registered in the name of Kent P. Dauten, as Agent, representing 
the Escrow Indemnity Funds shall be withheld from the Merger Consideration 
hereunder and shall be deposited with the Escrow Agent.  In accordance with 
the terms of the Escrow Agreement, each Stockholder shall be entitled to 
receive all ordinary cash dividends paid in respect of his or her 
Proportionate Share of Acquiror Stock that would otherwise be registered in 
his or her name but for such shares being a part of the Escrow Indemnity Funds 
and to vote and to give consents, waivers and ratifications in respect of his 
or her Proportionate Share of Acquiror Stock which is part of the Escrow 
Indemnity Funds.  In connection with any such vote or consent, the Agent and 
Acquiror, at Acquiror's expense, shall cause to be delivered to such 
Stockholder such information (including, without limitation, any proxy 
statement and cards).  The Agent shall vote the shares of Acquiror Stock 
forming part of the Escrow Indemnity Funds in accordance with the directions 
of the Stockholders.  In order to take such vote, the Agent shall tabulate the 
votes it receives from the Stockholders and inform Acquiror in writing of the 
aggregate percent of all votes received for, against and in abstention with 
respect to each matter voted upon.  Acquiror shall then convert such percent 
to number based on the then-existing Escrow Indemnity Funds, rounded in each 
case down to the nearest whole number.

     (c)     In the event there are no Unresolved Claims (as defined in the 
Escrow Agreement), as soon as reasonably practicable and in any event not 
later than the fifth day after the expiration of the Escrow Indemnity Period, 
or the next business day thereafter if such fifth day is not a business day, 
the Escrow Indemnity Funds then remaining shall be distributed to the 
Stockholders (or their nominee or transferee, as set forth in the Transmittal 
Documents in respect of the Exchange Merger Consideration) entitled thereto in 
accordance with their Proportionate Share (provided that cash in 



                                       41
<PAGE>

lieu of fractional shares will be distributed in accordance with Section 2.1(d)
hereof). In the event one or more Unresolved Claims with respect to the Escrow
Indemnity Funds, if any, shall exist upon the expiration of the Escrow Indemnity
Period, shares of Acquiror Stock, rounded to the nearest whole share, having a
Market Price equal to the sum of (i) the aggregate amount of such Unresolved
Claims and (ii) the amount reasonably estimated by Acquiror to cover the fees,
expense and other costs (including reasonable counsel fees and expenses) which
will be required to resolve such Unresolved Claims shall be retained as part of
the Escrow Indemnity Funds and the balance thereof, if any, shall be distributed
to the Persons entitled thereto. Upon the resolution of all such Claims and the
payment of all such fees, expenses and costs out of the Escrow Indemnity Funds,
the balance of the shares of Acquiror Stock, if any, shall be distributed to the
Persons entitled thereto. Acquiror agrees to pursue with reasonable diligence
the resolution of any Unresolved Claims existing after the expiration of the
Escrow Indemnity Period (but the failure to so pursue such resolution shall not
affect Acquiror's ability to recover its Losses and Expenses from the Escrow
Indemnity Funds, except to the extent such failure prejudices the Agent's
ability to defend against such Unresolved Claims).

     Section 8.4. Notice of Claims. If Acquiror believes that it has suffered or
incurred any Loss and Expense, it shall notify the Agent promptly in writing,
and in any event within the applicable time period specified in Section 8.1,
describing such Loss and Expense, all with reasonable particularity and
containing a reference to the provisions of this Agreement in respect of which
such Loss and Expense shall have occurred. If any Legal Action is instituted by
a third party with respect to which Acquiror intends to claim any liability or
expense as Loss and Expense under this Article, Acquiror shall promptly notify
the Agent of such Legal Action, but the failure to so notify the Agent shall not
affect Acquiror's ability to recover its Losses and Expenses from the Escrow
Indemnity Funds under this Article, except to the extent such failure to notify
prejudices the Agent's ability to defend against such Claim. With respect to
Losses and Expenses for which recovery could be made under any insurance
policies held prior to the Closing by the Company or any Company Subsidiary or
pursuant to indemnification obligations of a third party in favor of the Company
or any Company Subsidiary under any Acquisition Agreements, Acquiror undertakes
to use commercially reasonable efforts to pursue in good faith recovery under
such insurance policies or from such third-party indemnitors prior to Acquiror's
recovery from the Escrow Indemnity Funds in respect of a Claim for
indemnification with respect to such matters under this Agreement; provided,
however, that Acquiror shall be entitled to indemnification hereunder for any
costs, fees and expenses incurred by Acquiror in pursuing recovery under such
insurance policies or from such third-party indemnitors; and provided, further,
that any representation, warranty, covenant or agreement which is the subject of
a claim for insurance or for third-party indemnification which is asserted prior
to the expiration of the Escrow Indemnity Period shall survive (together with
Acquiror's right to indemnification in the immediately preceding proviso) for
purposes of a Claim hereunder with respect thereto until the final resolution
thereof. Acquiror agrees that, subject to the provisos in the immediately
preceding sentence, amounts actually received by Acquiror under the insurance
policies or from the third-party indemnitors described in the preceding sentence
shall not constitute Losses and Expenses for which Acquiror is entitled to
indemnification hereunder.



                                       42
<PAGE>

     Section 8.5. Defense of Third Party Claims. The Agent shall have the right
to conduct and control, through counsel of his own choosing, reasonably
acceptable to Acquiror, any third party Legal Action or other Claim (unless the
amount claimed under such Legal Action or other Claim exceeds the Escrow
Indemnity Funds, in which case Acquiror shall retain the right to control such
Legal Action or other Claim), but Acquiror may, at its election, participate in
the defense thereof at its sole cost and expense; provided, however, that if the
Agent shall fail to defend any such Legal Action or other Claim, then Acquiror
may defend, through counsel of its own choosing, such Legal Action or other
Claim, and (so long as it gives the Stockholders at least fifteen (15) days'
notice of the terms of the proposed settlement thereof and permits the
Stockholders to then undertake the defense thereof, except as set forth above)
settle such Legal Action or other Claim, and to recover out of the Escrow
Indemnity Funds the amount of such settlement or of any judgment and the costs
and expenses of such defense. The Agent shall not compromise or settle any such
Legal Action or other Claim without the prior written consent of Acquiror. All
reasonable costs and expenses defending any such third party Legal Action or
other Claim, including the amount of any settlement or of any judgment, shall be
paid out of the Escrow Indemnity Funds.

     Section 8.6. Company Indebtedness Calculation. Five business days prior to
the Closing Date, the Company shall prepare and deliver to Acquiror a schedule
showing the Company's best estimate of its Indebtedness as of the Effective Time
(the "Company Indebtedness Calculation"). If Acquiror disagrees with such
estimate, Representatives of the Company and Acquiror shall meet to discuss such
estimate, and the Company Indebtedness Calculation shall be revised, to the
extent agreed, to reflect such discussions. In addition, at the Closing, the
Company shall deliver to Acquiror a letter from First Source Financial LLP
certifying to Acquiror the entire unpaid balance (principal and interest) of the
Company Subsidiaries' Indebtedness to First Source Financial LLP, together with
all fees, expenses and other amounts (including so-called "breakage" amounts)
due in connection with the prepayment in full of such Indebtedness and the
termination of the commitments with respect thereto at the Closing, such that
the payment thereof at that time would terminate that Indebtedness. To the
extent any amounts in such letter shall not have previously been reflected in
the Company Indebtedness Calculation, the Company Indebtedness Calculation shall
be revised to include such amounts.

     Section 8.7. Exclusive Remedy. Except as otherwise provided in this
Article, the indemnification provided in this Article shall be the sole and
exclusive post-Closing remedy available to Acquiror against the Stockholders for
any Claim under this Agreement.

     Section 8.8. Determination of Loss and Expense. Any amounts paid to
Acquiror under Section 8.2 shall be treated as an adjustment to the Exchange
Merger Consideration. Any Loss and Expense that the Stockholders are required to
indemnify Acquiror against pursuant to Section 8.2 shall be adjusted to take
into account the present value of any Tax and insurance benefits realized or
reasonably expected to be realized by Acquiror as a result of incurring such
Loss and Expense (present value being determined using a discount rate equal to
7% per annum), taking into account the relevant effective Tax rates applicable
to Acquiror and the Tax attributes of Acquiror.

     Section 9.2. Headings. The headings contained in this Agreement are for
purposes of reference only and shall not affect in any way the meaning or
interpretation of this Agreement.

     Section 9.3. Severability. If any term or provision of this Agreement shall
be held or deemed to be, or shall in fact be, invalid, inoperative, illegal or
unenforceable as applied to any particular case in any jurisdiction or
jurisdictions, or in all jurisdictions or in all cases, because of the
conflicting of any provision with any constitution or statute or rule of public
policy or for any other reason, such circumstance shall not have the effect of
rendering the provision or provisions in question invalid, inoperative, illegal
or unenforceable in any other jurisdiction or in any other case or circumstance
or of rendering any other provision or provisions herein contained invalid,
inoperative, illegal or unenforceable to the extent that such other provisions
are not themselves actually in conflict with such constitution, statute or rule
of public policy, but this Agreement shall be reformed and construed in any such
jurisdiction or case as if such invalid, inoperative, illegal or unenforceable
provision had never been contained herein and such provision reformed so that it
would be valid, operative and enforceable to the maximum extent permitted in
such jurisdiction or in such case. Notwithstanding the foregoing, in the event
of any such determination the effect of which is to Affect Materially and
Adversely either party, the parties shall negotiate in good faith to modify this
Agreement so as to effect the original intent of the parties as closely as
possible to the fullest extent permitted by Applicable Law in an acceptable
manner to the end that the Transactions are fulfilled and consummated to the
maximum extent possible.

     Section 9.4. Entire Agreement. This Agreement (together with the
Confidentiality Agreements, the Disclosure Schedule, the Acquiror Disclosure
Schedule and the other Collateral Documents delivered in connection herewith)
constitutes the entire agreement of the Parties and supersedes all prior
agreements and undertakings, both written and oral (other than the
Confidentiality Agreements), between the Parties, or any of them, with respect
to the subject matter hereof.

     Section 9.5. Assignment. This Agreement shall not be assigned by operation
of law or otherwise and any purported assignment shall be null and void,
provided that Acquiror may cause a wholly owned Subsidiary of Acquiror to be
substituted for Acquiror Merger Subsidiary as the party to the Merger and may,
in addition, assign the other rights, but not its obligations, including,
without limitation, its obligation to pay the Merger Consideration, under this
Agreement to such Subsidiary.

     Section 9.6. Parties in Interest. This Agreement shall be binding upon and
inure solely to the benefit of each Party, and nothing in this Agreement,
express or implied, is intended to or shall confer upon any Person any right,
benefit or remedy of any nature whatsoever under or by reason of this Agreement.

     Section 9.7. Governing Law. The validity, interpretation, construction and
performance of this Agreement shall be governed by, and construed in accordance
with, the applicable laws of the United States of America and the laws of The
Commonwealth of Massachusetts applicable to contracts made and performed in such
State and, in any event, without giving effect to any choice 



                                       45
<PAGE>

or conflict of laws provision or rule that would cause the application of
domestic substantive laws of any other jurisdiction, except to the extent that
the provisions of the DGCL apply to the Merger. Anything in this Agreement to
the contrary notwithstanding, including without limitation the provisions of
Article 8, in the event of any dispute between the parties which results in a
Legal Action, the prevailing party shall be entitled to receive from the
non-prevailing party reimbursement for reasonable legal fees and expenses
incurred by such prevailing party in such Legal Action (it being understood that
the Escrow Indemnity Funds shall be the sole source of funds used to reimburse
the legal fees and expenses of Acquiror if Acquiror is the prevailing party).

     Section 9.8. Enforcement of the Agreement. Each Party recognizes and agrees
that each other Party's remedy at law for any breach of the provisions of this
Agreement would be inadequate and agrees that, subject to the exclusivity of the
indemnification remedy after Closing as provided in Section 8.7, for breach of
such provisions, such Party shall, in addition to such other remedies as may be
available to it at law or in equity or as provided in this Agreement, be
entitled to injunctive relief and to enforce its rights by an action for
specific performance to the extent permitted by Applicable Law. Each Party
hereby waives any requirement for security or the posting of any bond or other
surety in connection with any temporary or permanent award of injunctive,
mandatory or other equitable relief. Nothing herein contained shall be construed
as prohibiting a Party from pursuing any other remedies available to such Party
as provided in this Agreement for any breach or threatened breach hereof or
failure to take or refrain from any action as required hereunder to consummate
the Merger and carry out the Transactions.

     Section 9.9. Counterparts. This Agreement may be executed in one or more
counterparts, and by the different Parties hereto in separate counterparts, each
of which when executed shall be deemed to be an original but all of which taken
together shall constitute one and the same agreement.

     Section 9.10. Mutual Drafting. This Agreement is the result of the joint
efforts of Acquiror and the Company, and each provision hereof has been subject
to the mutual consultation, negotiation and agreement of the parties and there
shall be no construction against any Party based on any presumption of that
Party's involvement in the drafting thereof.
