Item 3.  Source and Amount of Funds or Other Consideration.

     The shares of Iron Mountain Incorporated Common Stock, par value $.01 per
share, were acquired on June 12, 1997, as a result of the merger of Safesite
Records Management Corporation ("Safesite") with and into Iron
Mountain/Safesite, Inc., a wholly-owned subsidiary of Iron Mountain
Incorporated.  Mr. Golisano was Chairman of Safesite and owned 5,275,185
shares of Safesite Common Stock which, in accordance with the Plan of Merger,
were exchanged for 1,023,875 shares of Iron Mountain Common Stock.  However,
it should be noted that while all Iron Mountain shares issued to Mr. Golisano
were registered with the Securities and Exchange Commission, only 356,939 were
freely tradeable.  584,855 shares are restricted by Iron Mountain Incorporated
By-Law from transfer or other disposition until June 12, 1998 and 82,081
shares are held in escrow until June 12, 1998 to satisfy certain claims which
Iron Mountain may have arising out of the Merger Agreement.  Mr. Golisano has
(i) sole voting power with respect to all of the shares (so long as held by
him or the escrow agent); (ii) sole dispository power with respect to 945,409
of the shares, subject to the By-Law limitation referred to previously, and
(iii) shared dispositive power with respect to the 82,081 shares held in
escrow (as to which Iron Mountain Incorporated and the escrow agent have sole
dispositive power until June 12, 1998 and Mr. Golisano has sole dispositive
power thereafter).

     Mr. Golisano also received, in exchange for his Safesite shares, cash in
the amount of $6,720,585.69 (and $16.36 in lieu of fractional shares).

     In accordance with the Plan of Merger, Mr. Golisano also exchanged
options to purchase 15,000 shares of Safesite common stock for options to
purchase 3,615 shares of Iron Mountain Common Stock.  The Iron Mountain
options are currently exercisable at prices ranging from $9.96 per share to
$13.65 per share and expire as to one-third of the shares optioned on January
1st of each of the next three (3) years.

                                 ARTICLE 2.

             CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

     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 Common Stock, par value $.01 per share, of the Company
(the "Company Stock") issued and outstanding immediately prior to the
Effective Time (other than any shares of Company Stock to be cancelled
pursuant to Section 2.1(b) and any Dissenting Shares), shall be converted into
the right to receive, subject to the indemnification provisions of Article 8
hereof, (i) that number equal to the Stock Conversion Number of fully paid and
nonassessable shares of Acquiror Stock (the "Stock Merger Consideration") and
(ii) cash in an amount equal to the Cash Conversion Number (the "Cash Merger
Consideration", and together with the Stock Merger Consideration, the "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
multiplied by the number 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 multiplied by the number 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 be converted into and become one
share of common stock of the Surviving Corporation with the same rights,
powers and privileges as the shares so converted and shall constitute the only
outstanding shares of capital stock of the Surviving Corporation.
<PAGE>
     (d)  In lieu of issuing fractional shares, Acquiror shall convert a
holder's right to receive shares of Acquiror Stock pursuant to Sections 2.1(a)
and Section 2.1(e) into a right to receive the highest whole number of shares
of Acquiror Stock constituting the non-cash portion of the Exchange Merger
Consideration to be received plus cash equal to the fraction of a share of
Acquiror Stock to which the holder would otherwise be entitled (in each case
after giving effect to Section 1.2(e) hereof) multiplied by the Determination
Price, and the Exchange Merger Consideration to which a holder is so 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 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 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.

     (e)  In order to implement the indemnification provisions of Section 8
hereof, the Stock Merger Consideration payable to each Stockholder pursuant to
Section 2.2 prior to the termination of the Escrow Indemnity Period hereof
shall be equal to the product of (i) the Closing Stock Conversion Number and
(ii) the number of Shares represented by Certificates held by such
Stockholder.  The remainder of such Stockholder's Stock Merger Consideration
shall be held as part of the Escrow Indemnity Funds and shall be payable to
such Stockholder after the Escrow Indemnity Period in accordance with Section
8 hereof and the Escrow Agreement.

     Section 2.2.   Exchange of Certificates; Exchange Agent and Exchange
Procedures.

     (a)  As soon as reasonably practicable after the Effective Time, 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 Cash Merger Consideration multiplied by the number of all
Shares issued and outstanding immediately prior to the Effective Time (other
than Shares to be cancelled pursuant to Section 2.1(b) and any Dissenting
Shares) (said number of Shares less said Shares to be cancelled and less said
Dissenting Shares hereafter to be referred to as the "Net Shares"), and (ii)
the Stock Merger Consideration multiplied by the Net Shares, plus cash in an
amount sufficient to make payment for fractional shares, in exchange for all
of the outstanding Shares, less the number of shares of Acquiror Stock
constituting the Escrow Indemnity Funds (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.
<PAGE>
     (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 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.

     (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.
<PAGE>
     (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 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.   Option Securities

     (a)  As soon as reasonably practicable after the Effective Time, each
holder of an Option Security who elects to shall receive (i) subject to clause
(ii) below, in respect of any such Option Security or portion thereof which is
exercisable at the Effective Time (including those which will become
exercisable by virtue of the consummation of the Merger) (1) a non-qualified
option to acquire shares of Acquiror Stock under Acquiror's 1995 Stock
Incentive Plan, which option for Acquiror Stock shall (A) have an exercise
price per share determined by dividing the exercise price per share of the
applicable Option Security by the Stock Conversion Number and (B) entitle the
holder to purchase that number of shares equal to the product of (x) the
number of shares subject to such Option Security which as of the Effective
Time is exercisable and (y) the Stock Conversion Number, and (2) cash in the
amount of the product of (x) the number of shares subject to such Option
Security which as of the Effective Time is exercisable and (y) the Cash
Conversion Number, and (ii) in respect of any such Option Security or portion
thereof which is not exercisable at the Effective Time and in respect of those
Option Securities to acquire 17,500 shares of Company Stock recently granted
to the five individuals identified in Section 3.13(b) of the Disclosure
Schedule, a non-qualified option to acquire shares of Acquiror Stock under
Acquiror's 1995 Stock Incentive Plan at an exercise price and in an amount
affording the holder equivalent value for the Option Security being exchanged,
which option for Acquiror Stock shall (1) have an exercise price per share
determined by dividing (x) the exercise price per share of the applicable
Option Security by (y) the quotient of the Share Price divided by the
<PAGE>
Determination Price, and (2) entitle the holder to purchase that number of
shares as equals the product of (x) the number of shares subject to such
Option Security which as of the Effective Time is not exercisable and (y) the
quotient of the Share Price divided by the Determination Price.  In addition,
each option to acquire Acquiror Stock issued in accordance with this Section
2.4 shall be exercisable (subject to the terms of such Option Security and
Acquiror's 1995 Stock Incentive Plan) on the date the applicable Option
Security would have been exercisable and otherwise be subject to the terms and
conditions of the Acquiror 1995 Stock Incentive Plan (it being understood that
the terms of the Acquiror option agreement, as to any employee, other than the
Principal Stockholders, of the Company who is not employed by Acquiror or any
of its Affiliates on the first anniversary of the Closing Date, shall not (a)
make it a condition to exercise such option that such employee be in
compliance with an Acquiror confidentiality or non-competition agreement and
(b) require such employee to pay to Acquiror the excess of the fair market
value on the day of exercise over the exercise price as a result of being
employed by a competitor of Acquiror within two years after the exercise of
such option).

     (b)  In lieu of issuing any option to acquire a fractional share of
Acquiror Stock, Acquiror shall convert a holder's right to receive an option
pursuant to this Section 2.4 into a right to receive an option to acquire the
nearest whole number of shares of Acquiror Stock (with no adjustment to any
cash amount received in connection with the conversion of an Exercisable
Option).

     (c)  Notwithstanding the foregoing, in lieu of issuing cash in respect of
exercisable Option Securities, Acquiror reserves the right, in its sole
discretion, subject to notification to the Company not less than ten (10) days
prior to the Closing Date, to exchange each vested and exercisable Option
Security solely for an option to acquire Acquiror Stock, the terms and
conditions (including, without limitation, the amount and exercise price per
share) of which will be determined in accordance with clause (a)(ii) above.

     Section 2.5.   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, upon surrender, in the manner provided in
Section 2.2, of the Certificate or Certificates that formerly evidenced such
Shares.
<PAGE>
     (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 2.6    Standstill.

     (a)  Until the first anniversary of the Effective Time, except as
permitted by Acquiror's Restated By-Laws, any Person who receives or is
entitled to receive at the Effective Time any shares of Acquiror Stock
pursuant to Section 2.1 shall not Transfer (as such term is defined in Exhibit
2.6 hereto), and Acquiror shall not be required to register the Transfer of,
the number of shares, rounded upward to the nearest whole share (the "Subject
Shares"), of Acquiror Stock equal to the product of (1) the quotient obtained
by dividing (x) the "Lock-up Value" by (y) the product of (A) the Common Stock
Amount and (B) the lesser of the Closing Price and the Determination Price
multiplied by (2) the Stock Merger Consideration received by such Person in
connection with the Merger. The "Lock-up Value" shall mean one half of the
sum of  (x) the product of the Common Stock Amount and  the lesser of the
Closing Price and the Determination Price plus (y) the Cash Amount.  The
"Closing Price" shall mean the closing price per share of Acquiror Stock for
the trading day immediately prior to the Effective Time.  The closing price
for such trading day shall be the last quoted sale price or, if not so quoted,
the average of the low bid and high asked prices on the Nasdaq National Market
System.

     (b)  Each certificate representing Subject Shares issued pursuant to the
Merger shall bear the following legend:

          "The shares represented by this certificate may not be transferred
     prior to [first anniversary date of the Effective Time to be inserted]
     except as otherwise permitted by the Restated By-Laws of the Corporation.
     A copy of the Restated By-Laws of the Corporation will be furnished
     without charge upon written request addressed to the Corporation at 745
     Atlantic Avenue, Boston, Massachusetts 02111, Attention:  Chief Executive
     Officer."

The Subject Shares shall not form a part of the shares of Acquiror Stock to be
held in escrow as part of the Escrow Indemnity Funds.

     (c)  In order to implement the provisions of this Section 2.6, the
Restated By-Laws of Acquiror shall be amended on or prior to the Closing Date
to include the provisions as to the limitations on the transferability of the
Acquiror Stock set forth in Exhibit 2.6 hereto."

                                 ARTICLE 3.

     The Company hereby represents and warrants to, and for Section 3.16

     of merger and related filings under the DGCL in connection with the
     Merger and the Transactions and except pursuant to the HSR Act.

     Section 3.5.   Title to Properties; Leases.

     (a)  The Company does not own any real property.  To the Company's

property it leases.  The Company has good indefeasible and merchantable title
to all other assets, tangible and intangible, reflected on the most recent

real estate) held by the Company for use in its business if not so reflected,
or purported to have been acquired by the Company since such date, except

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 Company Disclosure

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 holds real or personal property has been duly authorized,
executed and delivered by the Company 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 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, the Company 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
<PAGE>
personal property, none of which, to the Company's knowledge, contains any
provision which would impair the Company's ability to use such property as it
is currently used by the Company, 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, neither the Company nor any
other party thereto is in default in the performance, observance or
fulfillment of any obligation, covenant or condition contained in any such
Lease.

and complete description of all real estate leased by the Company.

     (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 conforms to

are necessary for the ownership by the Company of its properties and the
conduct of its business as now conducted or as presently proposed to be

as set forth in Section 3.6 of the Disclosure Schedule, (i) the Company is not
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,

     Company or, to the Company's knowledge, which are threatened or
     contemplated against, the Company or  any of its 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 would reasonably be expected to have an Adverse Effect on the
     Company; and
<PAGE>
          (ii)  to the Company's knowledge, each Governmental Authorization to
     which the Company is subject and which relates to the business,
     operations, properties, prospects, condition (financial or other), or
     results of operations of the Company, all of which are in full force and
     effect, except as set forth in Section 3.7(a)(ii) of the Disclosure
     Schedule.

     (b)  To the Company's knowledge, the Company has obtained all
Governmental Authorizations which are necessary for the ownership or use of
its properties and the conduct of its business as now conducted or as

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) the Company is not 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 Sections 3.7(a) or 3.7(b) of
the Disclosure Schedule, if adversely determined against the Company, 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.

registered in the offices as indicated therein.  To the Company's knowledge,
the Company owns or possesses or otherwise has the right to use all Intangible
Assets necessary for the present and planned future 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
the Company to conduct its business as currently conducted or proposed to be

to such a proposal relating to an Other Transaction, and the identity of the
Person making it.  The Company shall further advise Acquiror of the status and
changes in the material terms of any such proposal or inquiry (or any
amendment to any of them).  During the term of this Agreement, the Company
shall not enter into any agreement oral or written, and whether or not legally
binding, with any Person that provides for, or in any way facilitates, an
Other Transaction, or affects any other obligation of the Company under this
Agreement.

     Section 5.5.   Directors' and Officers' Indemnification and Insurance.
From and after the Effective Time, the Surviving Corporation shall indemnify,
defend and hold harmless the present and former officers and directors of the
Company against all Claims or amounts that, with the approval of the Surviving
Corporation as to settlements only, are paid in settlement of or otherwise in
connection with any Claim based in whole or in part on the fact that such
Person is or was a director or officer of the Company 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 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.  Acquiror hereby guarantees the
performance by the Surviving Corporation of all of its obligations in this
Section 5.5 and the payment of all sums which would be due hereunder from the
Surviving Corporation.

     Section 5.6.   Notification of Certain Matters.  Each party shall give
prompt notice to the other of  the occurrence or non-occurrence of any Event
the occurrence or non-occurrence of which would be likely to cause in any
material respect (i) any representation or warranty made by it contained in
this Agreement to be untrue or inaccurate, or (ii) any change to be made in
the Disclosure Schedule or the Acquiror Disclosure Schedule, as the case may
be, or (iii) any failure of the Company or Acquiror, as the case may be, to
comply with or satisfy, or be able to comply with or satisfy, any material
covenant, 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 shall not limit or otherwise affect the remedies available
hereunder to the Party receiving such notice.

     Section 5.7.   Public Announcements.  Until the Closing, or in the event
of termination of this Agreement, each party shall consult with the other
before issuing any press release or otherwise making any public statements
with respect to this Agreement, the Merger or any Transaction and shall not
issue any such press release or make any such public statement without the
prior consent of the other, which consent shall not be unreasonably withheld
or delayed.  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 with, and
exercise in good faith, all reasonable business efforts to agree with 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.
<PAGE>
     Section 5.8.   Obligations of Acquiror.  Acquiror agrees to take all
action necessary to cause Acquiror Merger Subsidiary and the Surviving
Corporation to perform their respective obligations under this Agreement.
Acquiror shall be liable as provided herein for any breach of any
representation, warranty, covenant or agreement of Acquiror Merger Subsidiary
and for any breach of this covenant.

     Section 5.9.   Employee Benefits; Severance Policy.  Provided that it
complies in all material respects with Applicable Law, the Surviving
Corporation may, in its sole discretion, substitute employee compensation,
benefit and severance programs for those of the Company as are comparable with
the programs provided from time to time to Acquiror's employees and the
employees of Acquiror's Subsidiaries.

     Section 5.10.  Certain Actions Concerning Business Combinations.  The
Company will not apply, and will not take any action resulting in the
application of, or otherwise elect to apply, the provisions of applicable
state takeover laws, if any, with respect to or as a result of the Merger or
the Transactions.

     Section 5.11.  Conversion of Option Securities.  The Company will take
all action necessary (a) to provide timely written notice to all persons
holding Option Securities to the effect that all Option Securities outstanding
as of the Effective Time will be exchanged for options to acquire Acquiror
Stock, and cash, in the case of vested and exercisable Option Securities, upon
such exchange, in accordance with Section 2.4 hereof, and (b) to obtain any
consent or waiver from the holder of an Option Security which may be necessary
to give effect to actions contemplated by Section 2.4.  Without the prior
written consent of Acquiror, except as set forth in Section 3.13(b) of the
Disclosure Schedule, (i) such notice will not cause an acceleration of the
exercise, conversion or vesting schedule of any Option Security, and (ii) the
Company will not otherwise accelerate, or cause an acceleration of, the
exercise, exchange or vesting schedule of any Option Security.

     Section 5.12.  Tax Treatment.  Each of Acquiror, Acquiror Merger
Subsidiary and the Company shall use its reasonable best efforts to cause the
Merger to qualify as a tax-free reorganization under the provisions of Section
368(a) of the Code and to obtain the opinions of counsel referred to in
Sections 6.2(j) and 6.3(d). Without limiting the foregoing, Acquiror covenants
that it will not dispose of the Company, whether by sale of stock, sale of
assets, merger, consolidation, liquidation, redemption, or otherwise, for a
period of one year after the Closing Date, except as permitted under Section
368(a)(2)(C) of the Code and the administrative authorities under Section 368
of the Code, or unless it first shall have received an opinion of counsel,
addressed to Acquiror and the Stockholders, that the proposed disposition will
not affect the tax-free nature of the Merger.

     Section 5.13.  Preparation of the Registration Statement.

     (a)  Promptly following the date of this Agreement, Acquiror shall
prepare and file with the SEC the Registration Statement.  Each of the Company
and Acquiror shall use its reasonable best efforts to have the Registration
Statement declared effective under the Securities Act as promptly as
practicable after such filing.  The Company shall use its reasonable best
efforts to cause the Prospectus to be mailed to the Stockholders as promptly
as practicable after the Registration Statement is declared effective under
the Securities Act.  Acquiror shall also take any action (other than
qualifying to do business in any jurisdiction in which it is not now so
<PAGE>
qualified or consenting to service of process in any jurisdiction in which it
has not previously so consented in any action other than one arising out of
the offering of the Acquiror Stock in such jurisdiction) required to be taken
to qualify the Acquiror Stock to be issued in the Merger under any applicable
state securities or "blue sky" laws prior to the Effective Time, and the
Company shall furnish all information concerning the Company and the holders
of the Company Stock as may be requested in connection with any such action.

     (b)  The Company and Acquiror shall cooperate with each other and provide
to each other all information necessary in order to prepare the Registration
Statement.  Acquiror shall notify the Company promptly of the receipt of any
comments from the SEC or its staff and of any requests by the SEC or its staff
for amendments or supplements to the Registration Statement or for additional
information and shall supply the Company with copies of all correspondence
between Acquiror or any of its Representatives, on the one hand, and the SEC
or its staff, on the other hand, with respect thereto.  The Company and
Acquiror shall use their respective reasonable best efforts to respond to any
comments of the SEC with respect to the Registration Statement as promptly as
practicable.  If at any time prior to the Effective Time there shall occur any
event with respect to the Company or Acquiror or any of its Subsidiaries, as
the case may be, or with respect to other information supplied by the Company
or Acquiror, as the case may be, for inclusion in the Registration Statement,
in either case which event is required to be described in an amendment of, or
a supplement to, the Prospectus or the Registration Statement, such event
shall be so described, and such amendment or supplement shall be promptly
filed with the SEC and, as required by law, disseminated to the Stockholders.
Acquiror shall notify the Company promptly upon (i) the declaration by the SEC
of the effectiveness of the Registration Statement, (ii) the issuance or
threatened issuance of any stop order or other order preventing or suspending
the use of any prospectus relating to the Registration Statement, (iii) any
suspension or threatened suspension of the use of any prospectus relating to
the Registration Statement in any state, (iv) any proceedings commenced or
threatened to be commenced by the SEC or any state securities commission that
might result in the issuance of a stop order or other order or suspension of
use or (v) any request by the SEC to supplement or amend the Prospectus after
the effectiveness thereof.  Acquiror and, to the extent applicable, the
Company, shall use their reasonable best efforts to prevent or promptly remove
any stop order or other order preventing or suspending the use of any
prospectus relating to the Registration Statement and to comply with any such
request by the SEC or any state securities commission to amend or supplement
the Registration Statement or the Prospectus.

     (c)  None of the information supplied or to be supplied by the Company or
any Stockholder for inclusion in (i) the Registration Statement will, at the
time the Registration Statement is filed with the SEC, at any time it is
amended or supplemented or at the time it becomes effective under the
Securities Act, contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein not misleading, or (ii) the Prospectus or any other proxy
statement or information furnished to Stockholders in connection with the
Special Meeting will, at the date it is first mailed to the Stockholders or at
the time of the Special Meeting, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading.  The Prospectus and
the Registration Statement will comply as to form in all material respects
with the requirements of the Securities Act.  Notwithstanding the foregoing,
<PAGE>
no representation is made by the Company with respect to statements made or
incorporated by reference in the Registration Statement other than with
respect to information which is supplied by the Company or any Stockholder
specifically for inclusion or incorporation by reference in the Registration
Statement.

          (ii)    in the event (A) neither Acquiror nor Acquiror Merger
     Subsidiary is in breach of this Agreement and none of their

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 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.

     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

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

writing signed by the Party or Parties to be bound thereby.

     Section 7.5.   Fees, Expenses and Other Payments.
<PAGE>

     (b)  The Company agrees that if this Agreement shall be terminated by
Acquiror pursuant to Section 7.1(d) (other than a termination by Acquiror

the Company of its covenants herein or the failure of the representations and
warranties of the Company to be true and correct in all material respects),
then the Company will pay to Acquiror an amount equal to $5,000,000, which
amount is in recognition of, among other things, the out-of-pocket Expenses of
Acquiror related to this Agreement, the reliance of Acquiror on the Company's
fulfillment of its obligations hereunder, the costs in delayed opportunity to
Acquiror, and the benefit to the Company, which heretofore has been a private
closely-held business, in establishing a market price for it, but which amount
shall not be considered to constitute liquidated damages.  Any payment
required to be made pursuant to this Section 7.5(b) shall be made as promptly

Agreement and, in any such case, shall be made by wire transfer of immediately
available funds to an account designated by Acquiror.

     (c)  Acquiror agrees that if this Agreement shall be terminated by the
Company pursuant to Section 7.1(c) (other than a termination by the Company
pursuant to Section 7.1(c)(ii)(B) unless the reason for the failure to
consummate the Merger prior to the Termination Date is due to any breach by
Acquiror or Acquiror Merger Subsidiary of any of their respective covenants
herein or the failure of the representations and warranties of Acquiror and
Acquiror Merger Subsidiary to be true and correct in all material respects),
then Acquiror will pay to the Company an amount equal to $5,000,000, which
amount is in recognition of, among other things, the out-of-pocket Expenses of
the Company related to this Agreement, the reliance of the Company on
Acquiror's fulfillment of its obligations hereunder, the costs in delayed
opportunity to the Company, but which amount shall not be considered to
constitute liquidated damages.  Any payment required to be made pursuant to
this Section 7.5(c) shall be made as promptly as practicable but not later
than ten business days after termination of this Agreement and, in any such
case, shall be made by wire transfer of immediately available funds to an
account designated by the Company.

     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.

                                 ARTICLE 8.

and in full force and effect for a period of one (1) year after the Closing
<PAGE>
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

     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 Collateral Document or any failure by the
Company to perform or fulfill any of its covenants or agreements set forth in
this Agreement or any Collateral Document;

     (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; or

     (c)  the Indebtedness of the Company and its Subsidiaries as of the
Effective Time exceeding $500,000 (unless any adjustment has been made to the
Cash Amount in accordance with Section 8.6).

     The Company hereby appoints, and by adopting and approving this Agreement
and the Merger, the Stockholders shall appoint, James B. Wayman, Jr. (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,
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 (ii) in no event shall the aggregate amount to be
paid to Acquiror exceed the lesser of (i) the Escrow Indemnity Funds and (ii)
shares of Acquiror Stock having an aggregate Market Value of Three Million
Dollars ($3,000,000).
<PAGE>
     (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 Fund 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 James B. Wayman, Jr., 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), on the date which is ten (10) days after the expiration of
the Escrow Indemnity Period, or the next business day if such date 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 the proportions with their ownership of
Shares immediately prior to the Effective Time (provided that cash in 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 shares,
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.
<PAGE>
     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 8.2, 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 relieve the Stockholders of their obligations
under this Article, except to the extent such failure to notify prejudices its
ability to defend against such Claim.

     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.   Balance Sheet Adjustment.  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 Fleet Bank of
Massachusetts, N.A. certifying to Acquiror the entire unpaid balance
(principal and interest) of the Company's Indebtedness to Fleet Bank of
Massachusetts, N.A., such that the payment thereof at that time would
terminate that Indebtedness. If the Company Indebtedness Calculation indicates
that the Indebtedness of the Company is greater than $500,000, the Cash Amount
shall be adjusted in accordance with the definition thereof; if the Company
Indebtedness Calculation indicates that Indebtedness of the Company is less
than $500,000, there shall be no such adjustment.

     Section 8.7.   Exclusive Remedy.  Except as otherwise provided in this
Article and Section 9.8 of the Merger Agreement and Section 5.1 of the
Stockholders' Agreement, 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 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
<PAGE>
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 Agreement, 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 Agreement), 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
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.

     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 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,
<PAGE>
mandatory or other equitable relief.  Nothing herein contained shall be
construed as prohibiting a Party from pursuing any other remedies available to
such Party 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.

     Section 9.11.  Continuation of Covenants. Notwithstanding any termination
by Acquiror of this Agreement, the Company agrees that all of the
representations, warranties and covenants of the Company contained in this
Agreement shall continue and be in full force and effect for so long as
Acquiror has the right to commence an offer to purchase the Company Stock of
the Principal Stockholders pursuant to the terms and provisions of the
Stockholders' Agreement and, in the event Acquiror commences such an offer,
until such time as such offer is consummated.

     2.   Section 2.4 of the Merger Agreement is hereby deleted and the
following new Section 2.4 is inserted in its place:

     "Section 2.4.  Option Securities.

          (a)  As soon as reasonably practicable after the Effective Time,
     each holder of an Option Security who elects to shall receive, subject to
     the indemnification provisions of Article 8 hereof, (i) subject to clause
     (ii) below, in respect of any such Option Security or portion thereof
     which is exercisable at the Effective Time (including those which will

     share of the applicable Option Security by the Stock Conversion Number
     and (B) entitle the holder to purchase that number of shares equal to the

     as of the Effective Time is exercisable and (y) the Stock Conversion
     Number, and (2) cash in the amount of the product of (x) the number of
     shares subject to such Option Security which as of the Effective Time is

     exercisable and (y) the Cash Conversion Number, and (ii) in respect of
     any such Option Security or portion thereof which is not exercisable at

     identified in Section 3.13(b) of the Disclosure Schedule, a non-qualified
     option to acquire shares of Acquiror Stock under Acquiror's 1995 Stock
     Incentive Plan at an exercise price and in an amount affording the holder
     equivalent value for the Option Security being exchanged, which option
     for Acquiror Stock shall (1) have an exercise price per share determined
     by dividing (x) the exercise price per share of the applicable Option
     Security by (y) the quotient of the Share Price divided by the
     Determination Price, and (2) entitle the holder to purchase that number
     of shares as equals the product of (x) the number of shares subject to
     such Option Security which as of the Effective Time is not exercisable
     and (y) the quotient of the Share Price divided by the Determination
     Price.  In addition, each option to acquire Acquiror Stock issued in
     accordance with this Section 2.4 shall be exercisable (subject to the
     terms of such Option Security and Acquiror's 1995 Stock Incentive Plan)
     on the date the applicable Option Security would have been exercisable
     and otherwise be subject to the terms and conditions of the Acquiror 1995

     herein, the cash to be received herein by any holder of an Exercisable
     Option prior to the termination of the Escrow Indemnity Period shall be
     adjusted to give full effect to the indemnification provisions of Article
     8 hereof.

          (b)  In lieu of issuing any option to acquire a fractional share of
     Acquiror Stock, Acquiror shall convert a holder's right to receive an
     option pursuant to this Section 2.4 into a right to receive an option to
     acquire the nearest whole number of shares of Acquiror Stock (with no
     adjustment to any cash amount received in connection with the conversion
     of an Exercisable Option).

          (c)  Notwithstanding the foregoing, in lieu of issuing cash in
     respect of exercisable Option Securities, Acquiror reserves the right, in
     its sole discretion, subject to notification to the Company not less than
     ten (10) days prior to the Closing Date, to exchange each vested and

     fraction of a share of Acquiror Stock to which the holder would otherwise

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

paid to Acquiror exceed the lesser of (i) the Escrow Indemnity Funds and (ii)
shares of Acquiror Stock having an aggregate Market Value of Three Million

     (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 Fund 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

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

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), on the date which is ten (10) days after the expiration of
the Escrow Indemnity Period, or the next business day if such date 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 the proportions with their ownership of
Shares immediately prior to the Effective Time (provided that cash in 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 shares,
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."

     18.  The Merger Agreement is hereby further amended by deleting Exhibit
8.3 thereto in its entirety and inserting in lieu thereof a new Exhibit 8.3
thereto substantially in the form of Exhibit 8.3 hereto.

     19.  Article 10 of the Merger Agreement is hereby amended by adding the
following new definitions to appear in the Merger Agreement in alphabetical
order with the other definitions:

     "Closing Stock Conversion Number shall mean the quotient obtained by
dividing (i) the difference between (a) the Common Stock Amount and (b) the
Escrow Indemnity Funds by (ii) the sum of (a) the number of shares of Company
Stock issued and outstanding immediately prior to the Merger (except shares
subject to Section 2.1(b)) and (b) the number of shares of Company Stock which
may be issued pursuant to Option Securities which are exercisable as of the
Effective Time (including those which will become exercisable by virtue of the
consummation of the Merger)."

     "Market Price" shall have the meaning set forth in the Escrow Agreement."

     "Proportionate Share" shall have the meaning set forth in the Escrow

represents and warrants that all requisite corporate action necessary for the
valid execution and delivery of this Amendment No. 2 has been duly and
effectively taken (including, without limitation, that the Company's Board of
Directors have unanimously approved the execution of this Amendment)

     23.  This Amendment No. 2 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.

     IN WITNESS WHEREOF, Acquiror, Acquiror Merger Subsidiary and the Company
have caused this Amendment No. 2 to be executed as of the date first written
above by their respective officers thereunto duly authorized.

Escrow Indemnity Funds to be delivered to Acquiror in connection with each
payment hereunder shall be calculated by Acquiror and shall be equal to the
quotient obtained by dividing (i) the Claimed Amount (as defined in Section
2.4) by (ii) the average closing price per share of Acquiror Stock for the
period of 20 trading days ending three trading days prior to the date of such
payment (the "Market Price").  The closing price for each such trading day
shall be the last quoted sale price or, if not so quoted, the average of the
low bid and high asked prices on the Nasdaq National Market System.

          (b)  The Escrow Agent may make any payments out of the Escrow
Indemnity Funds that may at the time be permitted to be made under the
provisions of Section 2.4 below, and shall make all such payments that at the
time are required to be made under such provisions or are jointly requested in
writing by Acquiror and the Agent.  Any payment which would result in the
disbursement of a fractional share of Acquiror Stock shall be rounded to the
nearest whole share.  In the event that any payment is made pursuant to this
Agreement, Acquiror shall deliver to the Escrow Agent a new certificate
registered in the name of James B. Wayman, Jr., as Agent, representing the
Escrow Indemnity Funds less such shares disbursed in the payment and all
previous payments.

          (c)  In the event there are no Unresolved Claims (as hereinafter
defined), on the date which is ten (10) days after the expiration of the
Escrow Indemnity Period, or the next business day if such date is not a
business day, Acquiror shall deliver or cause to be delivered to the Escrow
Agent cash in lieu of fractional shares calculated in accordance with the
second to last sentence of this paragraph (c) and separate certificates
registered in each Stockholder's name (or, in the event of a transfer of
ownership of Acquiror Stock which is not registered in the transfer records of
the Company, in the name of a transferee who has presented documents
reasonably required to evidence and effect such transfer and evidence that any
applicable stock transfer taxes have been paid), representing such
Stockholder's Proportionate Share of the Escrow Indemnity Funds, less such
Stockholder's Proportionate Share of all portions thereof, if any,

          (i)  paid to Acquiror pursuant to subparagraphs (a) and (b) above,
               and

          (ii) which are the subject of Unresolved Claims (as hereinafter
               defined).

The Escrow Agent shall retain the portion of the Escrow Indemnity Funds which
relates to all Unresolved Claims until resolution of such Unresolved Claims in
accordance with the terms 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 with a
Market Price measured as of the date of such expiration (such number to be
determined by Acquiror) 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 Stockholders entitled thereto.  Upon the
resolution of all such Unresolved Claims and the payment of all such fees,
expenses and costs out of the Escrow Indemnity Funds, the balance of the
<PAGE>
Acquiror Stock, if any, shall be distributed to the Stockholders entitled
thereto in accordance with the terms hereof. In lieu of issuing fractional
shares pursuant to this paragraph (c), each Stockholder shall receive the
highest whole number of shares of Acquiror Stock to which he or she is
entitled plus cash equal to the fraction of a share of Acquiror Stock to which
the Stockholder would otherwise be entitled multiplied by the Market Price of
the Acquiror Stock determined by Acquiror as of the date three days prior to
the distribution of such shares.  Promptly after such receipt, the Escrow
Agent will deliver such certificates together with any cash in lieu of
fractional shares to each respective Stockholder (or transferee) at the
addresses to be supplied by Acquiror in accordance with Acquiror's written
instructions.  Acquiror shall make all calculations relating to shares of
Acquiror Stock or cash in lieu of fractional shares, and the Escrow Agent
shall not be responsible for determining the accuracy of any such calculation.

     2.3  Unresolved Claims.  The term "Unresolved Claims" shall mean any
claim or request made pursuant to the Merger Agreement against the Escrow
Indemnity Funds in accordance with the Merger Agreement and Section 2.4 below,
until such time as such claim or request has been paid in full or otherwise
fully settled, compromised or adjusted by Acquiror, the Agent and the Escrow
Agent or by a final order of a court of competent jurisdiction resolving such
claim, from which no appeal is or can be taken.

     2.4  Notice of Request; Dispute Notice.  If at any time during the term
of this Agreement, Acquiror believes that it is entitled to any portion of the
Escrow Indemnity Funds, then Acquiror shall furnish to the Escrow Agent (with
a simultaneous copy to the Agent), a notice (the "Indemnity Notice of
Request") setting forth the cash amount (the "Claimed Amount") to which
Acquiror believes it is entitled and the reasons for such belief.  If the
Escrow Agent does not receive, within fifteen (15) business days after receipt
of the Indemnity Notice of Request, a notice from the Agent (the "Indemnity
Dispute Notice") with a simultaneous copy to Acquiror that a dispute (the
"Indemnity Dispute") exists relating to Acquiror's right to that portion of
the Escrow Indemnity Funds claimed in the Indemnity Notice of Request, the
Escrow Agent shall, immediately after such fifteen business day period,
release to Acquiror the certificate then held by the Escrow Agent pursuant to
the terms of this Agreement in exchange for a new certificate registered in
the name of James B. Wayman, Jr., as Agent, representing a number of shares of
Acquiror Stock equal to the quotient obtained by dividing (a) the difference
between, if positive, the Market Price of the shares of Acquiror Stock
represented by the certificate being released calculated as of the date three
trading days prior to such exchange and the Claimed Amount by (b) such Market
Price, and the Escrow Agent shall hold such replacement certificate for
Acquiror Stock or money pursuant to the terms of this Agreement.

     In the event the Escrow Agent receives an Indemnity Dispute Notice that
an Indemnity Dispute exists, the Escrow Agent shall retain custody of that
portion of the Escrow Indemnity Funds which relates to the Unresolved Claim
until the first to occur of the following events:

          (a)  Receipt by the Escrow Agent of a notice ("Indemnity Settlement
     Notice") signed by Acquiror and the Agent that the Indemnity Dispute has
     been resolved, said notice to contain instructions to Escrow Agent
     regarding delivery of that portion of the Escrow Indemnity Funds which
     relates to the Unresolved Claim; or
<PAGE>
          (b)  Receipt by Escrow Agent of a final order of a court of
     competent jurisdiction (the "Indemnity Award") resolving the Indemnity
     Dispute and directing the disposition of that portion of the Escrow
     Indemnity Funds;

after which Escrow Agent shall promptly pay that portion of the Escrow
Indemnity Funds which relates to the Indemnity Unresolved Claim in accordance
with the Indemnity Settlement Notice or the Indemnity Award.

     2.5     Maximum Distributions.  Notwithstanding anything in this
Agreement to the contrary, in no event shall Acquiror be entitled to received
shares of Acquiror Stock having an aggregate value of greater than $3,000,000
(calculated, in each case, based on the shares of Acquiror Stock being
disbursed multiplied by the Market Price employed in connection with such
disbursement).  At such time as the aggregate amount paid to Acquiror
(calculated in accordance with the foregoing sentence) equals $3,000,000, any
remaining Escrow Indemnity Funds shall be disbursed to the Stockholders and
this Agreement shall terminate, all in accordance with the other provisions of
this Agreement.

                                  ARTICLE 3

                                ESCROW AGENT

     3.1  Appointment.  Acquiror, the Company and the Agent hereby appoint the
Escrow Agent to serve hereunder and the Escrow Agent hereby accepts such
appointment and agrees to perform all duties which are expressly set forth in
this Agreement.

     3.2  Compensation.  The Escrow Agent shall be entitled to compensation
for legal fees incurred in connection with the preparation of this Agreement
and for its services hereunder in accordance with the attached fee schedule,
which may be subject to change hereafter on an annual basis, upon notice to
Acquiror and the Agent.  Compensation of the Escrow Agent and all reasonable
expenses of the Escrow Agent (including all reasonable attorneys' fees of
those attorneys not regularly in its employ) in connection with the
performance of its services hereunder shall be borne one half by Acquiror and
one half by the Agent.  The Escrow Agent shall be entitled to reimbursement on
demand for all reasonable out-of-pocket expenses incurred in connection with
the administration of this Agreement or the escrow created hereby which are in
excess of its compensation for normal services hereunder, including without
limitation, payment of any reasonable legal fees and expenses reasonably
incurred by the Escrow Agent in connection with the resolution of any claim in
any party hereunder.

     3.3  Indemnification.  Notwithstanding anything to the contrary in the
foregoing, Acquiror and the Agent will at their joint and several expense hold
the Escrow Agent, its directors, officers and employees harmless and indemnify
the Escrow Agent in connection with any and all third party claims, losses,
judgments or costs, regardless of their nature, arising out of or because of
this Agreement, except such as may arise because of the Escrow Agent's gross
negligence or willful misconduct or breach of this Agreement (including,
without limitation, Article 2 hereof).  Any such expense in the preceding
sentence as between Acquiror and the Agent shall be borne jointly and
severally by Acquiror and the Agent.  Acquiror and the Agent also exonerate
said Escrow Agent from any liability in connection with this Agreement or with
the administration of its duties hereunder, including but not limited to
reasonable legal fees and other reasonable costs and expenses of defending or
<PAGE>
preparing to defend against any claim or liability except such as may arise
because of the Escrow Agent's gross negligence or willful misconduct in
performing its specified duties hereunder or breach of this Agreement
(including, without limitation, Article 2 hereof).  Nothing in this Section
3.3 shall constitute a waiver of any claim which Acquiror and the Agent may
have against the other for contribution arising from their joint obligations
to hold the Escrow Agent harmless hereunder.  Anything in this Agreement to
the contrary notwithstanding, in no event shall the Escrow Agent be liable for
special, indirect or consequential loss or damage of any kind whatsoever
(including but not limited to lost profits), even if the Escrow Agent has been
advised of the likelihood of such loss or damage and regardless of the form of
action.  The Escrow Agent shall not be obligated to take any legal or other
action hereunder which might in its judgment involve any expense or liability
unless it shall have been furnished with acceptable indemnification.

     3.4  Resignation; Removal.  The Escrow Agent may resign at any time upon
giving the parties hereto 30 days' prior written notice.  Acquiror and the
Agent may also, at any time, mutually agree in a writing signed by Acquiror
and the Agent to remove the Escrow Agent upon 30 days' prior written notice.
In either event, the successor Escrow Agent shall be such person, firm or
corporation as shall be mutually selected by Acquiror and the Agent.  It is
understood and agreed that such resignation or removal shall not be effective
until a successor agrees to act hereunder by signing a copy hereof; provided,
however, if no successor is appointed and acting hereunder within thirty (30)
days after such notice is given, the Escrow Agent may pay and deliver the
Escrow Indemnity Funds into a court of competent jurisdiction.

                                  ARTICLE 4

                         LIABILITIES OF ESCROW AGENT

     4.1  Limitations.

          (a)  The Escrow Agent shall be liable only to accept, hold and
deliver the Escrow Indemnity Funds in accordance with the provisions of this
Agreement and any amendments hereto or other written instructions executed by
Acquiror and the Agent; provided, however, that the Escrow Agent shall not
incur any liability with respect to (a) any action taken or omitted in good
faith and with due care upon the reasonable advice of its counsel, including
in-house counsel, given with respect to any questions relating to the duties
and responsibilities of the Escrow Agent under this Agreement, or (b) any
action taken or omitted in reliance upon any instrument which the Escrow Agent
shall in good faith and with due care believe to be genuine (including the
execution of such instrument, the identity or authority of any person
executing such instrument, its validity and effectiveness, and the truth and
accuracy of any information contained therein), to have been signed by a
proper person or persons and to conform to the provisions of this Agreement.

          (b)  The Escrow Agent does not have any interest in the Escrow
Indemnity Funds deposited hereunder but is serving as escrow holder only and
having only possession thereof.  The Agent, on behalf of the Stockholders,
covenants and agrees that he will pay or reimburse the Escrow Agent upon
request for any transfer taxes, to the extent that any exist, relating to the
Escrow Indemnity Funds incurred in connection herewith.  Any payments or
income from the Escrow Indemnity Funds shall be subject to withholding
regulations then in force with respect to United States taxes.  The Agent, on
behalf of the Stockholders, agrees to assume any and all obligations imposed
now or hereafter by any applicable tax law with respect to the payment of
<PAGE>
Escrow Indemnity Funds under this Agreement to the Stockholders, and to
indemnify and hold the Escrow Agent harmless from and against any taxes,
additions for late payment, interest, penalties and other expenses, that may
be assessed against the Escrow Agent in any such payment or other activities
under this Agreement.  Acquiror and the Agent undertake to instruct the Escrow
Agent in writing with respect to the Escrow Agent's responsibility for
withholding and other taxes, assessments or other governmental charges,
certifications and governmental reporting in connection with its acting as
Escrow Agent under this Agreement.  The Agent agrees to hold the Escrow Agent
harmless and the Agent agrees to indemnify the Escrow Agent for any liability
on account of taxes, assessments or other governmental charges, including
without limitation the withholding or deduction or the failure to withhold or
deduct the same, and any liability for failure to obtain proper certifications
or to properly report to governmental authorities, to which the Escrow Agent
may be or become subject in connection with any payment to the Stockholders
under this Agreement, including costs and expenses (including reasonable legal
fees and expenses), interest and penalties.  The parties hereto agree that,
for tax reporting purposes, all interest or other income earned in the Escrow
Indemnity Funds shall be allocable to the Stockholders.

     Acquiror agrees to assume any and all obligations imposed now or
hereafter by any applicable tax law with respect to the payment of Escrow
Indemnity Funds under this Agreement to Acquiror, and to indemnify and hold
the Escrow Agent harmless from and against any taxes, additions for late
payment, interest, penalties and other expenses, that may be assessed against
the Escrow Agent in any such payment or other activities under this Agreement.
Acquiror agrees to hold the Escrow Agent harmless and Acquiror agrees to
indemnify the Escrow Agent for any liability on account of taxes, assessments
or other governmental charges, including without limitation the withholding or
deduction or the failure to withhold or deduct the same, and any liability for
failure to obtain proper certifications or to properly report to governmental
authorities, to which the Escrow Agent may be or become subject in connection
with any payment to Acquiror under this Agreement or which otherwise arises
out of this Agreement, except as provided in the preceding paragraph,
including costs and expenses (including reasonable legal fees and expenses),
interest and penalties.

     The Escrow Agent shall have no more or less responsibility or liability
on account of any action or omission of any book-entry depository or subescrow
agent employed by the Escrow Agent than any such book-entry depository or
subescrow agent has to the Escrow Agent, except to the extent that such action
or omission of any book-entry depository or subescrow agent was caused by the
Escrow Agent's own gross negligence, bad faith or willful misconduct.

     No distributions will be made unless Acquiror and the Agent provide the
Escrow Agent with an appropriate W-9 form for tax identification number
certification or non-resident alien certification prior to distribution.  This
Section 4.1(b) and Section 3.3 hereof shall survive any termination of this
Agreement or the resignation or removal of the Escrow Agent.

     4.2  Collateral Agreements.  Other than this Agreement, which shall be
controlling in regards to the Escrow Indemnity Funds, the Escrow Agent shall
not be bound in any way by any contract or agreement between other parties
hereto, including the Merger Agreement and the Stockholders' Agreement,
whether or not it has knowledge of any such contract or agreement or of its
terms or conditions.

                           STOCKHOLDERS' AGREEMENT


          AGREEMENT, dated as of February 19, 1997, among Iron Mountain

in his individual capacity and as custodian for Alexander B. Wayman and
Catherine Lia Wayman and those other stockholders of the Company which have
become party hereto by execution of an instrument in accordance with Section
6.8 hereof  (the "Additional Stockholders" and, together with the Initial
Stockholders, the "Stockholders").

                            W I T N E S S E T H:

          WHEREAS, each of the Initial Stockholders is the beneficial and
record owner of the shares of Common Stock, $.01 par value per share (the
"Company Stock") of the Company, set forth opposite each such Initial
Stockholder's name on Schedule A-1;

          WHEREAS, concurrently with the execution of this Agreement, Acquiror
and the Company are entering into an Agreement and Plan of Merger (the "Merger
Agreement") pursuant to which a wholly owned subsidiary of Acquiror will be
merged with and into the Company (the "Merger"), with the Company continuing

                       REPRESENTATIONS AND WARRANTIES
                             OF THE STOCKHOLDERS

          2.1  Representations and Warranties of the Stockholders.  Each
Stockholder represents and warrants, severally but not jointly, to Acquiror as
follows:
<PAGE>
          (a)  Ownership of Company Shares.  Except as disclosed in Section
2.1(a) of the letter from the Stockholders to Acquiror, dated the date hereof
or the date such Stockholder becomes party hereto (the "Stockholder Disclosure
Letter"), such Stockholder is the beneficial owner of the shares of Company
Stock set forth opposite such Stockholder's name on Schedule A-1, free and
clear of all Liens and, except for this Agreement and the Merger Agreement,
there are no options, warrants or other rights, agreements, arrangements or
commitments of any character to which such Stockholder is a party relating to
the pledge, disposition or voting of any shares of the Company Stock that are
owned by such Stockholder, and there are no voting trusts or voting agreements
with respect to such shares.  The shares of Company Stock set forth opposite
such Stockholder's name on Schedule A-1 constitute all of the outstanding
shares of capital stock of the Company owned beneficially or of record by such
Stockholder and such Stockholder does not have any options, warrants or other
rights to acquire any additional shares of capital stock of the Company or any
security exercisable or exchangeable for, or convertible into, shares of
capital stock of the Company other than as set forth on Schedule A-1.

          (b)  Authority to Execute and Perform Agreements.  Such Stockholder
has the full legal right and power and all authority required to enter into,
execute and deliver this Agreement and to perform fully such Stockholder's
obligations hereunder.  The execution and delivery of this Agreement by such
Stockholder have been duly authorized by all requisite organizational action,
if any, on the part of such Stockholder.  This Agreement has been duly
executed and delivered and constitutes the legal, valid and binding obligation
of such Stockholder enforceable against such Stockholder in accordance with
its terms (subject to the Enforceability Exceptions).

          (c)  No Conflicts; Consents.  (i) Except as set forth in Section
2.1(c) of the Stockholder Disclosure Letter, the execution and delivery by
such Stockholder of this Agreement do not, and the consummation of the
transactions contemplated hereby will not, conflict with or result in any
violation of or default (with or without notice or lapse of time, or both)
under (A) any contract, agreement or other binding arrangement to which such
Stockholder is a party or (B) any judgment, order, writ, injunction or decree
of any court, governmental body, administrative agency or arbitrator
applicable to such Stockholder.

          (ii)  Except as set forth in Section 2.1(c) of the Stockholder
Disclosure Letter, no Governmental Authorizations or Private Authorizations
are required to be obtained or made by such Stockholder in connection with the
execution and delivery by such Stockholder of this Agreement and the
consummation of the transactions contemplated hereby.

          (d)  Information Supplied.  None of the information specifically
supplied or to be supplied by such Stockholder with respect to such
Stockholder for inclusion or incorporation by reference in (i) the
Registration Statement will, at the time the Registration Statement is filed
with the SEC and at the time it becomes effective under the Securities Act,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated thereon or necessary to make the statements therein
not misleading and (ii) the proxy statement to be delivered to all
stockholders of the Company (the "Proxy Statement") will, at the date the
Proxy Statement is first mailed to the Company's Stockholders and at the time
of the special meeting of Company Stockholders for the purpose of voting on
the Merger Agreement, contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which they
are made, not misleading.
<PAGE>
          (e)  Investigation.  Such Stockholder has had a full opportunity to
review and discuss this Agreement, the Escrow Agreement and the Merger
Agreement (including, without limitation, with respect to the representations
and warranties in the Merger Agreement and the related Disclosure Schedule)
and to ask all questions of the Company and its directors and executive
officers necessary in order for such Stockholder to make an informed decision
to enter into this Agreement.

          (f)  Intent to Transfer Shares.  Such Stockholder has, and as of the
Closing Date, will have, no present plan or intention (an "Intention") to
sell, transfer, exchange, pledge (other than in a pre-existing bona fide
margin account) or otherwise dispose of, including a distribution by a
partnership to its partners, or a corporation to its shareholders, or any
other transaction which results in a reduction of ownership (any of the
foregoing, a "Sale") of any of the shares of Acquiror Stock issued to such
Stockholder in the Merger, or any securities that may be paid as a dividend
otherwise distributed thereon or with respect thereto, or issued or delivered
in exchange or substitution therefor or upon exercise of options held by such
Stockholder.  For purposes of the preceding sentence, shares of Acquiror Stock
(or the portion thereof) with respect to which a Sale will occur prior to the
Merger shall be considered to be shares of Company Stock that are exchanged
for Acquiror Stock in the Merger and then disposed of pursuant to an
Intention.  A Sale of Acquiror Stock shall be considered to have occurred
pursuant to an Intention if, among other things, such Sale occurs in a related
transaction.  Subject to Section 3.8, each Stockholder (i) reserves the rights
at any time after the Closing Date to evaluate his or her investment
portfolio, including shares of Acquiror Stock and any other securities issued
by Acquiror, in light of new, material developments, and to make such
investment decision with respect to such securities as such Stockholder and
his or her investment advisors, if any, shall deem to be in his or her best
interests, and (ii) specifically disavows any undertaking to hold any
securities issued by Acquiror for any specific period.

                                 ARTICLE III

                                  COVENANTS

          3.1  No Disposition or Acquisition of Shares.  Each Initial
Stockholder agrees that, except as set forth in Section 3.1 of the Stockholder
Disclosure Letter, such Initial Stockholder shall not sell, transfer, pledge,
hypothecate, encumber or otherwise dispose of (except upon such Stockholder's
death), or enter into any contract, option or other arrangement or
understanding with respect to the sale, transfer, pledge, hypothecation,
encumbrance or other disposition of, any of the shares of Company Stock set
forth opposite his or her name on Schedule A-1; provided, however, that each
Initial Stockholder shall have the right to transfer such shares to a
Permitted Assignee if such Permitted Assignee becomes a party to this
Agreement and agrees to be bound by the terms hereof.  Each Initial
Stockholder agrees that the certificates representing the shares of Company
Stock owned by him shall bear a legend indicating that such shares are subject
to this Agreement, which legend may be removed upon termination of this
Agreement.
<PAGE>
          3.2  Voting Arrangements.  Each of Golisano and Wayman agrees that,
except pursuant to this Agreement, he shall not grant any proxies, deposit any
shares of Company Stock into a voting trust or enter into any voting agreement
with respect to any shares of Company Stock now or hereafter owned,
beneficially or of record, by him, other than proxies to vote such shares at
any annual or special meeting of Stockholders of the Company on matters
unrelated to the matters set forth in Section 4.1 hereof.

          3.3  Satisfaction of Conditions to the Merger.  Each of Golisano and
Wayman agrees that each, in his capacity as a Stockholder, shall assist and
cooperate with the parties to the Merger Agreement in doing all things
necessary, proper or advisable under Applicable Laws as promptly as
practicable to consummate and make effective the Merger and the other
Transactions and  each of them shall not take any action that would or is
reasonably likely to result in any of its representations and warranties set
forth in this Agreement being untrue as of the date made or in any of the
conditions set forth in Article 6 of the Merger Agreement not being satisfied.
In addition, (i) Acquiror, Golisano and Wayman agree that they will enter
into, or, in the case of Acquiror, cause its nominee to enter into, and, in
the case of Golisano and Wayman, cause their Affiliate which owns any Property
to enter into, a purchase and sale agreement relating to each Property
reasonably satisfactory in form and substance to Acquiror, Golisano and
Wayman, for the price of $2,200,000 for the Property located at 5 Fortune
Drive, Billerica, Massachusetts, $2,400,000 for the Property located at 96
High Street, Billerica, Massachusetts, and $2,700,000 for the Property located
at 520 Metro Park West, Rochester, New York, and (ii) Acquiror, Golisano and
Wayman agree that they will enter into the Registration Rights Agreement.

          3.4  No Solicitation.  Each Stockholder agrees that he shall not,
nor shall he permit any of such Stockholder's Representatives (including,
without limitation, any investment banker, attorney or accountant retained by
such Stockholder) to, initiate, solicit or facilitate, directly or indirectly,
any inquiries or the making of any proposal with respect to an Other
Transaction, engage in any discussions or negotiations concerning, or provide
to any other person any information or data relating to, such Stockholder for
the purposes of, or otherwise cooperate in any way with or assist or
participate in, or facilitate any inquiries or the making of any proposal
which constitutes, or may reasonably be expected to lead to, a proposal to
seek or effect an Other Transaction, or agree to or endorse any Other
Transaction; provided, however, that nothing contained in this Section shall
prohibit any Stockholder, if such Stockholder is a member of Board of
Directors of the Company, from making any disclosure, in his or her capacity
as a director of the Company, to other Stockholders of the Company that, in
the reasonable judgment of the Company's Board of Directors in accordance
with, and based upon the written advice of, outside counsel, is required under
Applicable Law.  Each Stockholder shall promptly advise Acquiror of, and
communicate the material terms of, any proposal such Stockholder may receive,
or any inquiries such Stockholder receives which may reasonably be expected to
lead to such a proposal relating to an Other Transaction, and the identity of
the Person making it.  Each Stockholder shall further advise Acquiror of the
status and changes in the material terms of any such proposal or inquiry (or
any amendment to any of them).  During the term of this Agreement, each
Stockholder agrees that he shall not enter into any agreement oral or written,
and whether or not legally binding, with any Person that provides for, or in
any way facilitates, an Other Transaction, or affects any other obligation of
the other Stockholders under this Agreement.
<PAGE>
          3.5  Standstill.  Golisano agrees that, (i) from the date hereof
until the Closing Date and (ii) from and after the Closing Date for so long as
he shall be a Restricted Stockholder, he shall not, and shall use his best
efforts to cause his Affiliates not to, without the prior written consent of
the board of directors of Acquiror, (A) in any manner acquire, agree to
acquire or make any proposal to acquire, directly or indirectly, any Equity
Securities of Acquiror or any rights or options to acquire such Equity
Securities (other than the shares of Acquiror Stock received by him in the
Merger), (B) propose to enter into, directly or indirectly, a merger or other
business combination involving Acquiror or propose to purchase, directly or
indirectly, a material portion of the assets of Acquiror, (C) make, or in any
way participate, directly or indirectly, in, any "solicitation" of "proxies"
(as such terms are used in Regulation 14A under the Exchange Act) to vote or
consent or seek to advise or influence any Person with respect to the voting
of, or granting of a consent with respect to, any Voting Securities of
Acquiror, (D) form, join or in any way participate in a "group" (within the
meaning of Section 13(d)(3) of the Exchange Act) for the purpose of acquiring,
holding voting or disposing of any Equity Securities of Acquiror, (E)
otherwise act, alone or in concert with others, to seek to control or
influence in any public manner or public forum the management or policies of
Acquiror; provided, however, that the foregoing shall not limit the ability to
vote any shares of any Equity Securities of Acquiror, (F) disclose any
intention, plan or arrangement inconsistent with the foregoing, (G) advise,
assist (including by knowingly providing or arranging financing for that
purpose) or encourage any other Person in connection with any of the foregoing
or (H) take any action which might require Acquiror to make a public
announcement regarding the possibility of a transaction between Golisano and
Acquiror (including any of their respective Affiliates).

          3.6  Non-Competition.

          (a)  Except with the prior written consent of Acquiror, for a period
of five years from the Closing Date or the date of the closing of the Offer,
each of Golisano and Wayman shall not disclose to others or use for his or
others' benefit confidential information related to the Company or Acquiror
and its Subsidiaries, including the names of customers, the contact persons at
customers, pricing, the software programs utilized by the Company or Acquiror
and its Subsidiaries in the operation of its business and all other
information material to the operation, management, marketing or financing of
the Company, Acquiror and its Subsidiaries which is not known or generally
available to the public or competitors in the records management or records
storage industries.

The confidentiality obligations of this Section shall not apply to information:

          (i)     which is required to be disclosed by judicial or
administrative process or order, or by other requirements of law;

          (ii)    which is or becomes generally available to the public other
than as a result of a breach of this Section;

          (iii)   which is received from a third party who obtained such
information other than under an obligation of confidentiality; or

          (iv)    which Acquiror discloses on a nonconfidential basis or
otherwise makes available to the general public or the trade.
<PAGE>
          (b)  Each of Golisano and Wayman agrees that he shall not, for a
period of five years from the Closing Date or from the date of the closing of
the Offer, directly or indirectly own, manage, engage in, participate in,
provide advice to, be employed by or have a financial interest in, any
enterprise which provides records management or records storage services to
business facilities located in any jurisdiction in which Acquiror or the
Company operates.

     This Section 3.6(b) shall not prohibit either Golisano or Wayman from
acquiring up to five percent (5%) of any class of securities registered
pursuant to the Exchange Act of any corporation which may engage in the
records management storage service business in direct competition with the
business of Acquiror within the geographical areas set forth in this Section
3.6.

          (c)  Each of Golisano and Wayman acknowledges that it has carefully
read all the terms herein stated and agrees that the same are necessary for
the reasonable and proper protection of the value of the Company; and that
each and every covenant is reasonable with respect to such matter, length of
time, and the geographical areas described; and that irrespective of all other
conditions, the covenants and restrictions hereinabove provided shall be
operative during the full period and throughout the geographical area
described.  In the event any court finds any such restraint or limitation to
be unreasonable, then it is the intent of the parties that such court should
determine the maximum restraint or limitation which is reasonable and
enforcement will be of that restraint or limitation.

          (d)  Each of Golisano and Wayman acknowledges that confidential
information in his possession related to the Company has particular value, the
loss of confidentiality of which by communication to unauthorized persons
cannot be reasonably or adequately compensated for by damages alone.
Moreover, each of Golisano and Wayman agrees that any breach of paragraphs (a)
and (b) of this Section 3.6 would give rise to damages which would be
difficult to calculate.  Therefore, the parties hereby agree that in the event
of a breach of any of the terms and conditions of this Section 3.6, Acquiror
shall be entitled to equitable relief by way of an injunction.  This Section
3.6 shall not be construed as a limitation upon Acquiror's remedies for such
breach.

          (e)  The restrictions contained in this Section 3.6 shall be broadly
construed by any court having jurisdiction of the matter in order to protect
Acquiror to the maximum degree possible.

          3.7  Tender Offer; Commitment to Sell.

          (a)  If Acquiror terminates the Merger Agreement pursuant to Section
7.1(d) thereof (other than a termination by Acquiror pursuant to Section
7.1(d)(ii)(B)(II) unless the reason for the failure to consummate the Merger
prior to the Termination Date is due to any breach by the Company of its
covenants therein or the failure of the representations and warranties of the
Company to be true and correct in all material respects), it shall have the
right, but not the obligation, to commence an offer (the "Offer") to purchase
all of the outstanding Shares at a per share purchase price (the "Offer
Consideration") equal to the Merger Consideration (assuming for such purposes
that the commencement of the Offer would constitute a Change of Control under
the Option Plans and, as a consequence thereof, there would be an acceleration
<PAGE>
of the Option Securities as of the date of commencement of the Offer, as set
forth in Section 3.13(b) of the Disclosure Schedule).  Shares tendered in the
Offer shall be free and clear of all Liens.  The Offer shall comply in all
material respects with Applicable Law.

          (b)  Each of Golisano and Wayman hereby agrees that they will
irrevocably tender their shares of Company Stock identified on Schedule A-1
hereto in any such Offer commenced by Acquiror and, in connection therewith,
transfer to Acquiror all of the right, title and interest of each of Golisano
and Wayman in and to such shares, free and clear of all Liens.

          (c)  All of the representations, warranties and covenants made by
the Company in the Merger Agreement shall be deemed made in connection with
the Offer by each Stockholder who tenders shares in the Offer, which
representations, warranties and covenants shall survive for a period of one
year after the closing of the Offer.  Any claim for indemnification in respect
of breaches of such representations, warranties and covenants shall be
conducted in accordance with the provisions of Article 8 of the Merger
Agreement and Article 5 of this Agreement (except that there will be no Escrow
Indemnity Fund).

          (d)  The closing of the Offer shall take place in accordance with
the instructions set forth in the Offer.  At such closing, (A) Acquiror shall
make payment of the Offer Consideration to each Stockholder who tenders their
shares in the Offer in shares of Acquiror Stock, which shares shall be duly
authorized, validly issued, fully paid and nonassessable, and the cash portion
of the Exchange Merger Consideration and cash in lieu of fractional shares,
(B) each of Golisano and Wayman shall deliver to Buyer evidence reasonably
satisfactory to Buyer and its counsel that all necessary authorizations,
consents, orders, waivers and approvals have been obtained to vest in Buyer
all of the right, title and interest of the Shares being transferred to Buyer
by them, and (C) each Stockholder who tenders Shares in the Offer shall
deliver to Acquiror the Certificates representing such Shares duly endorsed
for transfer to Acquiror or with stock powers duly executed by such
Stockholder and otherwise in a form and at the time which complies with the
terms of the Offer.

          (e)  It is the understanding of Acquiror, and each of Golisano and
Wayman hereby represents, that, in the event of an acquisition of shares of
Acquiror Stock in the Offer, each of Golisano and/or Wayman will be acquiring
the shares of Acquiror Stock to be acquired by him through the Offer for his
own account for investment with no intention of presently distributing or
reselling the same, subject, nevertheless, to his right to dispose of such
Shares, or any part of any thereof held by him, if at some future time in his
sole discretion he deems it advisable so to do.  Each of Golisano and Wayman
hereby agrees that he will not sell, transfer or otherwise dispose of any such
shares of Acquiror Stock in violation of the Securities Act, and that such
shares of Acquiror Stock may contain a legend, reasonably satisfactory to
Acquiror, referring to the provisions of this Section.  Each of Golisano and
Wayman understands that the Company is not and will not be required to file a
registration statement under the Securities Act in connection with any sale,
transfer or other disposition of shares of Acquiror Stock which may be
acquired by either Golisano or Wayman pursuant to the Offer.
<PAGE>
          (f)  The undertakings in this Section 3.7 shall terminate upon the
earlier of (i) the Effective Time, (ii) the termination of the Merger
Agreement in accordance with Section 7.1 thereof (other than a termination
which results in Acquiror having the right to make the Offer in accordance
with this Section 3.7) or (iii) six months after a termination which results
in Acquiror having the right to make the Offer in accordance with this Section
3.7 (provided that on or before thirty days after such termination Acquiror
shall have provided notice to Golisano of its intention to commence the
Offer).

          3.8  Post-Closing Transfer Restrictions.  In the event the Merger is
consummated as an Alternative Transaction, each of the Stockholders agrees
that, from and after the Closing Date until the one-year anniversary thereof,
such Stockholder shall not sell, transfer, pledge, encumber or otherwise
dispose of, including through any "short sale" or derivative transactions
(collectively "Transfer"), any shares of Acquiror Stock received by such
Stockholder as a result of the Merger if, after giving effect to such
Transfer, the aggregate number of shares of Acquiror Stock received in the
Merger by all Stockholders and not Transferred would be less than a number of
shares of Acquiror Stock having a value, as of the date of the Merger, of less
than fifty percent (50%) of the value of all of the formerly outstanding
Company Stock as of the same date.  For purposes of the preceding computation,
shares of Company Stock surrendered by dissenters or exchanged for cash in
lieu of fractional shares of Acquiror Stock will be treated as outstanding
Company Stock on the date of the Merger that has subsequently been
Transferred, and all shares of Company Stock and all shares of Acquiror Stock
held by the Stockholders and Transferred prior or subsequent to the Merger
will be included in the computation.

          3.9  [Intentionally Omitted.]

                                 ARTICLE IV

                             PROXY; CONVERSION;
                         ELECTIONS; WAIVER OF RIGHTS

          4.1  Proxy.  Each of Golisano and Wayman hereby agrees that, at any
meeting of the stockholders of the Company, however called, and at every
adjournment thereof, and in any action by written consent of the stockholders
of the Company, to (a) vote all of the shares of Company Stock then owned,
beneficially or of record, by him in favor of the adoption of the Merger
Agreement as in effect on the date hereof (as such agreement may be amended
(1) as contemplated by Section 7.3 of the Merger Agreement or (2) with the
consent of such Stockholder) and each of the other transactions contemplated
thereby and any action required in furtherance thereof, (b) vote such shares
against any action or agreement that would result in a breach in any material
respect of any covenant, representation or warranty or any other obligation of
the Company under the Merger Agreement, and (c) vote such shares against any
Other Transaction or any other action or agreement that, directly or
indirectly, is inconsistent with or that would, or is reasonably likely to,
directly or indirectly, impede, interfere with or attempt to discourage the
Merger or any other transaction contemplated by the Merger Agreement,
including, but not limited to (i) any extraordinary corporate transaction
(other than the Merger on the terms set forth in the Merger Agreement), such
as a merger, consolidation, business combination, reorganization
recapitalization or liquidation involving the Company, (ii) a sale or transfer
of a material amount of assets of the Company, or (iii) any material change in
<PAGE>
the Company's corporate structure or business; provided, however, that, if
either Golisano or Wayman is a member of the Board of Directors of the
Company, nothing herein shall be construed to obligate such Stockholder or
representative to act in his capacity as a director in any manner which may
conflict with such Person's fiduciary duties as a director of the Company.

          In furtherance of the foregoing, (i) each of Golisano and Wayman
hereby appoints Acquiror and the proper officers of Acquiror, and each of
them, with full power of substitution in the premises, its proxies to vote all
his shares of Company Capital Stock at any meeting, general or special, of the
Stockholders of the Company, and to execute one or more written consents or
other instruments from time to time in order to take such action without the
necessity of a meeting of the Stockholders of the Company, in accordance with
the provisions of the preceding paragraph and (ii) Acquiror hereby agrees to
vote such shares or execute written consents or other instruments in
accordance with the provisions of the preceding paragraph.

          The proxy and power of attorney granted herein shall be irrevocable
during the term of this Agreement, shall be deemed to be coupled with an
interest and shall revoke all prior proxies granted by such Golisano and
Wayman.  Each of Golisano and Wayman shall not grant any proxy to any person
which conflicts with the proxy granted herein, and any attempt to do so shall
be void.  The power of attorney granted herein is a durable power of attorney
and shall survive the disability or incompetence of such Stockholder.

          4.2  Appraisal Rights.  Each of Golisano and Wayman hereby waives
his rights to appraisal under Section 262 of the DGCL with respect to any
shares of Company Stock owned by him in connection with the transactions
contemplated by the Merger Agreement.  Each of Golisano and Wayman hereby
agrees that he will not in any way attempt to influence, encourage or persuade
any Person who beneficially owns any Company Stock to exercise any rights to
appraisal such Person may have pursuant to Section 262 of the DGCL in
connection with said transactions.

          4.3  Waiver of Certain Rights.  Each Initial Stockholder hereby
waives and agrees not to assert any claims or rights it may have against any
officer or director of the Company relating to or arising out of actions or
omissions occurring at or prior to the Effective Time or the closing of the
Offer, as the case may be, including, without limitation, in respect of
approval or adoption of the Merger Agreement or the consummation of the Merger
or the other transactions contemplated thereby.

                               INDEMNIFICATION

          5.1  Indemnification in the Event of the Offer.  Each Stockholder
agrees that the indemnification provisions set forth in Article 8 of the
Merger Agreement shall be applicable in the event Acquiror consummates the
Offer pursuant to Section 3.7 hereof; provided, however, that only
Stockholders who tender Shares in the Offer shall be responsible for such
indemnification and each such Stockholder shall only be responsible for such
Stockholder's Proportionate Share of any claim.  In addition, (i) the Escrow
Indemnity Period shall terminate on the first anniversary of the closing of
the Offer and the Closing Date shall be deemed to be the closing of the Offer,
<PAGE>
(ii) the amount of Acquiror Stock received by each Stockholder who tenders
Shares in the Offer shall be adjusted to reflect the escrow to be established,
and (iii) each Stockholder will agree to execute the Escrow Agreement with
such changes therein, if any, as are necessary to reflect the differences
between the Merger and the Offer.

          5.2  Exclusive Remedy.  Except as otherwise provided in Article 8
and Section 9.8 of the Merger Agreement, 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.

                                 ARTICLE VI

                                MISCELLANEOUS

to occur of (i) the mutual consent of Acquiror and all of the Stockholders,

consummation of the Merger and (iii) the tenth anniversary of the Closing
Date.

instrument executed by the parties or their respective successors or assigns.

consents and agrees that such scope may be judicially modified accordingly in
any proceeding brought to enforce such restriction.  In furtherance of the
foregoing, if any court construes any of the provisions of Section 3.6, or any
part thereof, to be unreasonable because of the duration of such provision or
the geographic scope thereof, such court shall have the power to reduce the
duration or restrict the geographic scope of such provision and to enforce
such provision as so reduced or restricted.

          6.7  Further Assurances.  Each party hereto shall execute and

                              ESCROW AGREEMENT


     This ESCROW AGREEMENT (this "Agreement") is entered into as of the 12th
day of June, 1997, by and among Iron Mountain Incorporated, a Delaware
corporation ("Acquiror"), Safesite Records Management Corporation, a Delaware
corporation (the "Company"), James B.  Wayman, Jr., an individual residing at
251 Old Billerica Road, Bedford, MA 01730 (in his capacity as agent for the
Stockholders, the "Agent"), as agent for the stockholders of the Company (the
"Stockholders"), and State Street Bank and Trust Company, as Escrow Agent (the
"Escrow Agent").

                            W I T N E S S E T H :

     WHEREAS, Acquiror and the Company entered into that certain Agreement and
Plan of Merger dated as of February 19, 1997, as amended (the "Merger
Agreement"), an executed copy of which has been provided to the Escrow Agent,
pursuant to which the Company will merge with and into a wholly owned
subsidiary of Acquiror (the "Merger"), and pursuant to which 141,836 shares of
Common Stock, par value $.01 per share of Acquiror ("Acquiror Stock") were
withheld from the consideration payable to the Stockholders and were allocated
to indemnify Acquiror for certain matters relating to the Merger Agreement,
all as is more fully set forth in the Merger Agreement;

     WHEREAS, this Agreement is being entered into pursuant to Article 8 of
the Merger Agreement; and

     WHEREAS, in accordance with and pursuant to Article 8 of the Merger
Agreement, the Agent has been appointed as agent and attorney-in-fact, with
full power of substitution, to take all actions called for by Article 8 of the
Merger Agreement, including, without limitation, the execution of this
Agreement;

     NOW, THEREFORE, in consideration of the foregoing premises and the
agreements set forth below, the receipt and adequacy of which are hereby
acknowledged, the parties hereto, intending to be legally bound, agree as
follows:

                                  ARTICLE 1

                           ESCROW INDEMNITY FUNDS

     1.1  Delivery.  Upon consummation of the Merger, Acquiror will deliver to
the Escrow Agent a certificate registered in the name of James B. Wayman, Jr.,
as Agent, representing 141,836 shares of Acquiror Stock (the "Escrow Indemnity
Funds").  The shares of Acquiror Stock represented by the Escrow Indemnity
Funds shall not be subject to the restrictions set forth in Article XII of
Acquiror's By-Laws.

     1.2  Receipt.  The Escrow Agent agrees to hold and disburse the Escrow
Indemnity Funds (together with interest earned thereon) solely in accordance
with the terms and conditions of this Agreement, pursuant to the written
direction of Acquiror, and for the uses and purposes stated herein.  The
Escrow Agent shall, upon receipt of the Escrow Indemnity Funds, issue written
acknowledgment to Acquiror and the Agent of receipt thereof.
<PAGE>
     1.3  Rights of Stockholders.

          (a)  In the case any distribution of capital or stock dividend shall
be made on or in respect of Acquiror Stock, or any money or property shall be
distributed with respect to Acquiror Stock, pursuant to a recapitalization or
reclassification of the capital of Acquiror, or pursuant to a reorganization
or liquidation or dissolution of Acquiror, any such money or property to be
distributed with respect to the Escrow Indemnity Funds shall be delivered to
the Escrow Agent to be held by it as part of the Escrow Indemnity Funds.
Acquiror shall forthwith deliver to the Escrow Agent an additional certificate
registered in the name of James B. Wayman, Jr., as Agent, representing any
such additional Acquiror Stock or such money and the Escrow Agent shall hold
such additional Acquiror Stock or money pursuant to the terms of this
Agreement.

          (b)  Each Stockholder shall be entitled to receive all ordinary cash
dividends paid in respect of his or her Proportionate Share (as defined below)
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.  The Agent shall pay over to each Stockholder, forthwith upon receipt,
his or her Proportionate Share of all ordinary cash dividends paid on the
Escrow Indemnity Funds, and, at the cost of Acquiror, shall execute and
deliver to each Stockholder such proxies or other documents in writing as may
be necessary to enable each Stockholder to exercise the foregoing rights.  In
connection with any vote or consent by the Stockholders with respect to shares
of Acquiror Stock which are part of the Escrow Indemnity Funds, the Agent
shall vote the shares of Acquiror Stock forming part of the Escrow Indemnity
Funds in accordance with the directions of the Stockholders to the Agent.  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 a number based on the
then-existing Escrow Indemnity Funds, rounded in each case down to the nearest
whole number. The term "Proportionate Share", as to each Stockholder, shall
mean such Stockholder's proportionate share of the total number of shares of
Aquiror Stock to be issued in connection with the Merger.

                                  ARTICLE 2

            PROCEDURES FOR DISBURSEMENT OF ESCROW INDEMNITY FUNDS

     2.1     Purpose.  The Escrow Indemnity Funds shall be held by the Escrow
Agent to secure the indemnification obligations to Acquiror under the Merger
Agreement and shall be held and released in accordance with the provisions of
this Agreement.  The Escrow Agent agrees to hold, disburse and invest the
Escrow Indemnity Funds solely in accordance with the terms and conditions of
this Agreement and for the uses and purposes stated herein.

     2.2  Disbursement.

          (a)  If at any time after the Closing Date and prior to the
termination of this Agreement, the Escrow Agent receives written instructions
in accordance with the terms of Section 2.4 hereof from Acquiror to make a
payment to Acquiror, then the Escrow Agent shall make payments out of the
Escrow Indemnity Funds to Acquiror, in accordance with such instructions and
with Section 2.4, unless the Escrow Indemnity Funds shall be insufficient to
<PAGE>
comply with such instructions, in which case the Escrow Agent shall pay the
entire Escrow Indemnity Funds to Acquiror and shall advise Acquiror and the
Agent in writing of the amount of such payment.  The number of shares of the
Escrow Indemnity Funds to be delivered to Acquiror in connection with each
payment hereunder shall be calculated by Acquiror and shall be equal to the
quotient obtained by dividing (i) the Claimed Amount (as defined in Section
2.4) by (ii) the average closing price per share of Acquiror Stock for the
period of 20 trading days ending three trading days prior to the date of such
payment (the "Market Price").  The closing price for each such trading day
shall be the last quoted sale price or, if not so quoted, the average of the
low bid and high asked prices on the Nasdaq National Market System.

          (b)  The Escrow Agent may make any payments out of the Escrow
Indemnity Funds that may at the time be permitted to be made under the
provisions of Section 2.4 below, and shall make all such payments that at the
time are required to be made under such provisions or are jointly requested in
writing by Acquiror and the Agent.  Any payment which would result in the
disbursement of a fractional share of Acquiror Stock shall be rounded to the
nearest whole share.  In the event that any payment is made pursuant to this
Agreement, Acquiror shall deliver to the Escrow Agent a new certificate
registered in the name of James B. Wayman, Jr., as Agent, representing the
Escrow Indemnity Funds less such shares disbursed in the payment and all
previous payments.

          (c)  In the event there are no Unresolved Claims (as hereinafter
defined), on the date which is ten (10) days after the expiration of the
Escrow Indemnity Period, or the next business day if such date is not a
business day, Acquiror shall deliver or cause to be delivered to the Escrow
Agent cash in lieu of fractional shares calculated in accordance with the
second to last sentence of this paragraph (c) and separate certificates
registered in each Stockholder's name (or, in the event of a transfer of
ownership of Acquiror Stock which is not registered in the transfer records of
the Company, in the name of a transferee who has presented documents
reasonably required to evidence and effect such transfer and evidence that any
applicable stock transfer taxes have been paid), representing such
Stockholder's Proportionate Share of the Escrow Indemnity Funds, less such
Stockholder's Proportionate Share of all portions thereof, if any,

          (i)  paid to Acquiror pursuant to subparagraphs (a) and (b) above,
               and

          (ii) which are the subject of Unresolved Claims (as hereinafter
               defined).

The Escrow Agent shall retain the portion of the Escrow Indemnity Funds which
relates to all Unresolved Claims until resolution of such Unresolved Claims in
accordance with the terms 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 with a
Market Price measured as of the date of such expiration (such number to be
determined by Acquiror) 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 Stockholders entitled thereto.  Upon the
resolution of all such Unresolved Claims and the payment of all such fees,
expenses and costs out of the Escrow Indemnity Funds, the balance of the
<PAGE>
Acquiror Stock, if any, shall be distributed to the Stockholders entitled
thereto in accordance with the terms hereof. In lieu of issuing fractional
shares pursuant to this paragraph (c), each Stockholder shall receive the
highest whole number of shares of Acquiror Stock to which he or she is
entitled plus cash equal to the fraction of a share of Acquiror Stock to which
the Stockholder would otherwise be entitled multiplied by the Market Price of
the Acquiror Stock determined by Acquiror as of the date three days prior to
the distribution of such shares.  Promptly after such receipt, the Escrow
Agent will deliver such certificates together with any cash in lieu of
fractional shares to each respective Stockholder (or transferee) at the
addresses to be supplied by Acquiror in accordance with Acquiror's written
instructions.  Acquiror shall make all calculations relating to shares of
Acquiror Stock or cash in lieu of fractional shares, and the Escrow Agent
shall not be responsible for determining the accuracy of any such calculation.

     2.3  Unresolved Claims.  The term "Unresolved Claims" shall mean any
claim or request made pursuant to the Merger Agreement against the Escrow
Indemnity Funds in accordance with the Merger Agreement and Section 2.4 below,
until such time as such claim or request has been paid in full or otherwise
fully settled, compromised or adjusted by Acquiror, the Agent and the Escrow
Agent or by a final order of a court of competent jurisdiction resolving such
claim, from which no appeal is or can be taken.

     2.4  Notice of Request; Dispute Notice.  If at any time during the term
of this Agreement, Acquiror believes that it is entitled to any portion of the
Escrow Indemnity Funds, then Acquiror shall furnish to the Escrow Agent (with
a simultaneous copy to the Agent), a notice (the "Indemnity Notice of
Request") setting forth the cash amount (the "Claimed Amount") to which
Acquiror believes it is entitled and the reasons for such belief.  If the
Escrow Agent does not receive, within fifteen (15) business days after receipt
of the Indemnity Notice of Request, a notice from the Agent (the "Indemnity
Dispute Notice") with a simultaneous copy to Acquiror that a dispute (the
"Indemnity Dispute") exists relating to Acquiror's right to that portion of
the Escrow Indemnity Funds claimed in the Indemnity Notice of Request, the
Escrow Agent shall, immediately after such fifteen business day period,
release to Acquiror the certificate then held by the Escrow Agent pursuant to
the terms of this Agreement in exchange for a new certificate registered in
the name of James B. Wayman, Jr., as Agent, representing a number of shares of
Acquiror Stock equal to the quotient obtained by dividing (a) the difference
between, if positive, the Market Price of the shares of Acquiror Stock
represented by the certificate being released calculated as of the date three
trading days prior to such exchange and the Claimed Amount by (b) such Market
Price, and the Escrow Agent shall hold such replacement certificate for
Acquiror Stock or money pursuant to the terms of this Agreement.

     In the event the Escrow Agent receives an Indemnity Dispute Notice that
an Indemnity Dispute exists, the Escrow Agent shall retain custody of that
portion of the Escrow Indemnity Funds which relates to the Unresolved Claim
until the first to occur of the following events:

          (a)  Receipt by the Escrow Agent of a notice ("Indemnity Settlement
     Notice") signed by Acquiror and the Agent that the Indemnity Dispute has
     been resolved, said notice to contain instructions to Escrow Agent
     regarding delivery of that portion of the Escrow Indemnity Funds which
     relates to the Unresolved Claim; or
<PAGE>
          (b)  Receipt by Escrow Agent of a final order of a court of
     competent jurisdiction (the "Indemnity Award") resolving the Indemnity
     Dispute and directing the disposition of that portion of the Escrow
     Indemnity Funds;

after which Escrow Agent shall promptly pay that portion of the Escrow
Indemnity Funds which relates to the Indemnity Unresolved Claim in accordance
with the Indemnity Settlement Notice or the Indemnity Award.

     2.5     Maximum Distributions.  Notwithstanding anything in this
Agreement to the contrary, in no event shall Acquiror be entitled to received
shares of Acquiror Stock having an aggregate value of greater than $3,000,000
(calculated, in each case, based on the shares of Acquiror Stock being
disbursed multiplied by the Market Price employed in connection with such
disbursement).  At such time as the aggregate amount paid to Acquiror
(calculated in accordance with the foregoing sentence) equals $3,000,000, any
remaining Escrow Indemnity Funds shall be disbursed to the Stockholders and
this Agreement shall terminate, all in accordance with the other provisions of
this Agreement.

                                  ARTICLE 3

                                ESCROW AGENT

     3.1  Appointment.  Acquiror, the Company and the Agent hereby appoint the
Escrow Agent to serve hereunder and the Escrow Agent hereby accepts such
appointment and agrees to perform all duties which are expressly set forth in
this Agreement.

     3.2  Compensation.  The Escrow Agent shall be entitled to compensation
for legal fees incurred in connection with the preparation of this Agreement
and for its services hereunder in accordance with the attached fee schedule,
which may be subject to change hereafter on an annual basis, upon notice to
Acquiror and the Agent.  Compensation of the Escrow Agent and all reasonable
expenses of the Escrow Agent (including all reasonable attorneys' fees of
those attorneys not regularly in its employ) in connection with the
performance of its services hereunder shall be borne one half by Acquiror and
one half by the Agent.  The Escrow Agent shall be entitled to reimbursement on
demand for all reasonable out-of-pocket expenses incurred in connection with
the administration of this Agreement or the escrow created hereby which are in
excess of its compensation for normal services hereunder, including without
limitation, payment of any reasonable legal fees and expenses reasonably
incurred by the Escrow Agent in connection with the resolution of any claim in
any party hereunder.

     3.3  Indemnification.  Notwithstanding anything to the contrary in the
foregoing, Acquiror and the Agent will at their joint and several expense hold
the Escrow Agent, its directors, officers and employees harmless and indemnify
the Escrow Agent in connection with any and all third party claims, losses,
judgments or costs, regardless of their nature, arising out of or because of
this Agreement, except such as may arise because of the Escrow Agent's gross
negligence or willful misconduct or breach of this Agreement (including,
without limitation, Article 2 hereof).  Any such expense in the preceding
sentence as between Acquiror and the Agent shall be borne jointly and
severally by Acquiror and the Agent.  Acquiror and the Agent also exonerate
said Escrow Agent from any liability in connection with this Agreement or with
the administration of its duties hereunder, including but not limited to
reasonable legal fees and other reasonable costs and expenses of defending or
<PAGE>
preparing to defend against any claim or liability except such as may arise
because of the Escrow Agent's gross negligence or willful misconduct in
performing its specified duties hereunder or breach of this Agreement
(including, without limitation, Article 2 hereof).  Nothing in this Section
3.3 shall constitute a waiver of any claim which Acquiror and the Agent may
have against the other for contribution arising from their joint obligations
to hold the Escrow Agent harmless hereunder.  Anything in this Agreement to
the contrary notwithstanding, in no event shall the Escrow Agent be liable for
special, indirect or consequential loss or damage of any kind whatsoever
(including but not limited to lost profits), even if the Escrow Agent has been
advised of the likelihood of such loss or damage and regardless of the form of
action.  The Escrow Agent shall not be obligated to take any legal or other
action hereunder which might in its judgment involve any expense or liability
unless it shall have been furnished with acceptable indemnification.

     3.4  Resignation; Removal.  The Escrow Agent may resign at any time upon
giving the parties hereto 30 days' prior written notice.  Acquiror and the
Agent may also, at any time, mutually agree in a writing signed by Acquiror
and the Agent to remove the Escrow Agent upon 30 days' prior written notice.
In either event, the successor Escrow Agent shall be such person, firm or
corporation as shall be mutually selected by Acquiror and the Agent.  It is
understood and agreed that such resignation or removal shall not be effective
until a successor agrees to act hereunder by signing a copy hereof; provided,
however, if no successor is appointed and acting hereunder within thirty (30)
days after such notice is given, the Escrow Agent may pay and deliver the
Escrow Indemnity Funds into a court of competent jurisdiction.

     4.1  Limitations.

          (a)  The Escrow Agent shall be liable only to accept, hold and
deliver the Escrow Indemnity Funds in accordance with the provisions of this
Agreement and any amendments hereto or other written instructions executed by
Acquiror and the Agent; provided, however, that the Escrow Agent shall not
incur any liability with respect to (a) any action taken or omitted in good
faith and with due care upon the reasonable advice of its counsel, including
in-house counsel, given with respect to any questions relating to the duties
and responsibilities of the Escrow Agent under this Agreement, or (b) any
action taken or omitted in reliance upon any instrument which the Escrow Agent
shall in good faith and with due care believe to be genuine (including the
execution of such instrument, the identity or authority of any person
executing such instrument, its validity and effectiveness, and the truth and
accuracy of any information contained therein), to have been signed by a
proper person or persons and to conform to the provisions of this Agreement.

          (b)  The Escrow Agent does not have any interest in the Escrow
Indemnity Funds deposited hereunder but is serving as escrow holder only and
having only possession thereof.  The Agent, on behalf of the Stockholders,
covenants and agrees that he will pay or reimburse the Escrow Agent upon
request for any transfer taxes, to the extent that any exist, relating to the
Escrow Indemnity Funds incurred in connection herewith.  Any payments or
income from the Escrow Indemnity Funds shall be subject to withholding
regulations then in force with respect to United States taxes.  The Agent, on
behalf of the Stockholders, agrees to assume any and all obligations imposed
now or hereafter by any applicable tax law with respect to the payment of
<PAGE>
Escrow Indemnity Funds under this Agreement to the Stockholders, and to
indemnify and hold the Escrow Agent harmless from and against any taxes,
additions for late payment, interest, penalties and other expenses, that may
be assessed against the Escrow Agent in any such payment or other activities
under this Agreement.  Acquiror and the Agent undertake to instruct the Escrow
Agent in writing with respect to the Escrow Agent's responsibility for
withholding and other taxes, assessments or other governmental charges,
certifications and governmental reporting in connection with its acting as
Escrow Agent under this Agreement.  The Agent agrees to hold the Escrow Agent
harmless and the Agent agrees to indemnify the Escrow Agent for any liability
on account of taxes, assessments or other governmental charges, including
without limitation the withholding or deduction or the failure to withhold or
deduct the same, and any liability for failure to obtain proper certifications
or to properly report to governmental authorities, to which the Escrow Agent
may be or become subject in connection with any payment to the Stockholders
under this Agreement, including costs and expenses (including reasonable legal
fees and expenses), interest and penalties.  The parties hereto agree that,
for tax reporting purposes, all interest or other income earned in the Escrow
Indemnity Funds shall be allocable to the Stockholders.

     Acquiror agrees to assume any and all obligations imposed now or
hereafter by any applicable tax law with respect to the payment of Escrow
Indemnity Funds under this Agreement to Acquiror, and to indemnify and hold
the Escrow Agent harmless from and against any taxes, additions for late
payment, interest, penalties and other expenses, that may be assessed against
the Escrow Agent in any such payment or other activities under this Agreement.
Acquiror agrees to hold the Escrow Agent harmless and Acquiror agrees to
indemnify the Escrow Agent for any liability on account of taxes, assessments
or other governmental charges, including without limitation the withholding or
deduction or the failure to withhold or deduct the same, and any liability for
failure to obtain proper certifications or to properly report to governmental
authorities, to which the Escrow Agent may be or become subject in connection
with any payment to Acquiror under this Agreement or which otherwise arises
out of this Agreement, except as provided in the preceding paragraph,
including costs and expenses (including reasonable legal fees and expenses),
interest and penalties.

     The Escrow Agent shall have no more or less responsibility or liability
on account of any action or omission of any book-entry depository or subescrow
agent employed by the Escrow Agent than any such book-entry depository or
subescrow agent has to the Escrow Agent, except to the extent that such action
or omission of any book-entry depository or subescrow agent was caused by the
Escrow Agent's own gross negligence, bad faith or willful misconduct.

     No distributions will be made unless Acquiror and the Agent provide the
Escrow Agent with an appropriate W-9 form for tax identification number
certification or non-resident alien certification prior to distribution.  This
Section 4.1(b) and Section 3.3 hereof shall survive any termination of this
Agreement or the resignation or removal of the Escrow Agent.

     4.2  Collateral Agreements.  Other than this Agreement, which shall be
controlling in regards to the Escrow Indemnity Funds, the Escrow Agent shall
not be bound in any way by any contract or agreement between other parties
hereto, including the Merger Agreement and the Stockholders' Agreement,
whether or not it has knowledge of any such contract or agreement or of its
terms or conditions.
