1.4      DEFERRED TRANSFERS.

                  (a)      If, on the Closing Date:

                           (i)      Seller or Buyer has not obtained any
authorization, approval, order, license, permit, franchise or consent from any
domestic or foreign government or governmental authority or any counterparty to
a contract (an "APPROVAL"):

                                    (A)   which is necessary in order to effect
the transfer of any of the Acquired Assets to Buyer pursuant to the terms and
conditions of this Agreement, or

                                    (B)   the absence of which would render such
transfer void or voidable or subject Buyer, Seller or any of their respective
officers, directors or agents to civil or criminal liability; or

                           (ii)     there is in effect any temporary or
appealable injunction, restraining order or decree of any nature of any court or
governmental agency or body of competent jurisdiction that restrains or
prohibits the transfer to Buyer of any Acquired Asset pursuant to the terms and
conditions of this Agreement, but which does

                                      -14-

<PAGE>

not prevent the conditions precedent to the Closing set forth in Section 5
from being satisfied (a "NON-FINAL INJUNCTION");

then, in each such case, such Acquired Assets (the "DEFERRED ITEMS") shall be
withheld from sale pursuant to the Agreement without any reduction in the
Purchase Price. From and after the Closing, Seller and/or Buyer shall
continue to use reasonable efforts to obtain all Approvals relating to the
Deferred Items or the transfer thereof and/or to cause all Non-Final
Injunctions relating to the Deferred Items or the transfer thereof to be
lifted; PROVIDED that Seller shall not be required to make any payments or
agree to any material undertakings in connection therewith.

                  (b)      Until such time as any Deferred Items have been
transferred to Buyer pursuant to Section 1.4(c) or otherwise disposed of in
accordance with Section 1.4(d) (each, a "DEFERRED TRANSFER"), the Deferred Items
shall be held for Buyer's benefit and the Acquired Assets comprising Deferred
Items shall be managed and operated by Seller for Buyer's benefit and account in
the manner hereinafter provided from the Closing to the time of the respective
Deferred Transfers, with all gains, income, losses, Taxes or other items
generated thereby to be for Buyer's account. Seller shall not have any liability
to Buyer arising out of the management or operation by Seller of any Acquired
Asset comprising Deferred Items, other than for gross negligence or willful
misconduct.

Buyer shall reimburse Seller and shall hold Seller harmless from and against all
liabilities incurred or asserted as a result of Seller's post-Closing direct or
indirect ownership, management, operation or sale (other than to Buyer) of the
Deferred Items,

                                      -15-

<PAGE>

including, without limitation, the amount of any additional Taxes payable by
Seller (whether currently or in the future) in excess of the amount of Taxes
which would have been payable by Seller, after application of the terms of this
Agreement, if the Deferred Items had been transferred to Buyer or any of its
Affiliates (as defined in Section 2.7(a)) on the Closing Date. Such
reimbursement shall be made by Buyer and received by Seller within five (5)
Business Days of Buyer's receipt of any bill, claim, invoice or other request
for payment from Seller. For purposes of this Agreement, "BUSINESS DAY shall
mean any day other than a Saturday or Sunday or a day on which banking
institutions located in New York, New York are permitted or required by law,
executive order or governmental decree to remain closed. From the Closing to the
date of the Deferred Transfer, Seller shall hold the Deferred Items and hold or
operate the Acquired Assets comprising the Deferred Items only in the ordinary
course substantially consistent with past practice; PROVIDED, HOWEVER, that
Seller shall not be required to finance the operations of the Business directly
or indirectly. Subject to applicable law and regulations (including, without
limitation, all laws and regulations requiring investment approvals or consents
or antimonopoly clearances, exemptions or waivers in connection with any
disposition of the Deferred Items, and all exchange controls and laws concerning
foreign corrupt practices, expatriation of funds or otherwise), Seller shall, in
respect of any Deferred Items, use all reasonable efforts to follow and
implement the reasonable written instructions and policies of Buyer relating to
the holding of the Deferred Items.

<PAGE>

                  (c)      Unless otherwise disposed of upon Buyer's
instructions in accordance with Section 1.4(d), the deeds, bills of sale,
endorsements, consents, assignments and other good and sufficient instruments of
conveyance and assignment relating to the relevant Acquired Assets as are
necessary under applicable law in order to transfer effectively such Deferred
Items, free and clear of all liens (except for liens which had existed on the
Closing Date and had been disclosed to Buyer and liens which were created for
Buyer's benefit during the period the Deferred Items were being held for Buyer's
benefit), will be delivered to Buyer on the date which is fifteen (15) Business
Days after all Approvals relating to any such Deferred Item or the transfer
thereof shall have been obtained and/or after any Non-Final Injunction relating
to any such Deferred Items or the transfer thereof has been lifted or on such
other date as the Parties hereto may mutually agree.

                  (d)      At any time prior to the Deferred Transfer relating
to any of the Deferred Items, Seller shall, on Buyer's written instructions
(subject to applicable law and regulations), or may at any time after twelve
(12) months from the Closing, with Buyer's consent (which shall not be
unreasonably withheld, conditioned or delayed), for Buyer's benefit, dispose of
the Deferred Items and remit the proceeds of such sale (less withholding or
similar Taxes, if any, payable with respect to such disposition or remittance)
to Buyer; PROVIDED, that Seller shall not have any liability to any third party
arising out of such transactions other than for gross negligence or willful
misconduct; and PROVIDED, FURTHER, that any amount remitted to Buyer pursuant to
this Section 1.4(d) shall be reduced by, to the extent not previously paid by or
on

                                      -17-

<PAGE>

behalf of Buyer pursuant to Section 1.4(b), the amount of any and all debts,
liabilities and other obligations described in Section 1.4(b) imposed upon or
incurred by Seller as a result of Seller's post-Closing direct or indirect
ownership, management, operation or sale of the Deferred Items, including,
without limitation, the amount of any Taxes (other than Taxes previously paid by
Buyer pursuant to Article IX), payable by Seller as a result thereof.

2.9      TAX MATTERS.

                 (a)      Each of Seller and SRT has filed with the appropriate
authorities all material Tax Returns (as defined below) that it was required to
file and all such Tax Returns were correct and complete, except for any error or
omission that would not reasonably be expected to have a material adverse
effect. Each of Seller and SRT has paid to the appropriate authorities all Taxes
(as defined below) required to have been paid (whether or not shown on such Tax
Returns). All material Taxes that either of Seller and SRT is or was required by
law to withhold or collect have been duly withheld or collected and, to the
extent required, have been paid to the proper Governmental Entity. For purposes
of this Agreement, "TAXES" means all taxes, including without limitation income,
gross receipts, ad valorem, value-added, excise, real property, personal

any tax or any contest or dispute thereof. For purposes of this Agreement, "TAX

Taxes.

                 (b)      No taxing authority has asserted in writing either to
Seller or SRT any adjustment, deficiency, or assessment relating to the Business

be liable. There is

<PAGE>


no pending audit, examination, formal proceeding or investigation, written
dispute or claim with or by a taxing authority for which either Seller or SRT is
or may be liable for additional Taxes with respect to the Business. No statute
of limitations with respect to any Taxes for which either Seller or SRT is or
may be liable has been waived or extended, which waiver or extension is
currently in effect. The due date of any Tax Returns that either Seller or SRT
is required to file is not currently the subject matter of an extension.

                 (c)      There are no liens on any of the Acquired Assets or
the assets of SRT which arose in connection with any failure or asserted failure
to pay any Taxes, other than liens for current Taxes not yet due and payable and
liens for Taxes which are being contested in good faith and by appropriate
proceedings.

                 (d)      SRT is not a party to any contract, agreement, loan or
arrangement that, individually or collectively, could give rise to any payment
that would not be deductible by reason of Section 162 or 404 of the Code.

Business, (ii) extensions of statutory limitations relating to the Business,
(iii) the federal, state and local income Tax Returns and franchise Tax Returns
of SRT, and (iv) material correspondence between SRT and all taxing authorities,
for its last three (3) years, previously have been made available to Buyer.

                 (f)      The provisions for Taxes and any reserve for Taxes, if
any, shown on the Most Recent Balance Sheet are adequate to cover the aggregate


                                      -28-
<PAGE>


liability of SRT arising out of facts or circumstances occurring on or prior to
the date of the Most Recent Balance Sheet for all Taxes.

                 (g)      SRT has not made any election under Section 341(f) of
the Code (or any corresponding provision of state or local income Tax law).

                 (h)      SRT has not been a member of a group with which it has
filed or been included in a combined, consolidated or unitary income Tax Return
other than a group the common parent of which was Thermo Electron Corporation.
SRT is not liable for the Taxes of any taxpayer other than Seller and its
Affiliates under Reg. Section 1.1502-6 (or any similar provision of state, local
or foreign law), as a transferee or successor, by contract, or otherwise for any
taxable period beginning before the Closing Date.

                 (i)      SRT is not obligated to make, and as a result of any
event connected with the transactions contemplated by this Agreement, will not
become obligated to make, any "excess parachute payment" within the meaning of

make an "excess parachute payment" within the meaning of Section 280G of the
Code.

2.10 TANGIBLE PERSONAL PROPERTY. Seller or SRT has good title to all of the
material tangible personal property reflected on the Most Recent Balance Sheet
(other than property sold, consumed or otherwise disposed of in the Ordinary
Course of Business since the date of the Most Recent Balance Sheet), free and
clear of all Security Interests. All of said material tangible personal property

provisions of ERISA and the Code and the regulations thereunder and other
applicable law.

Benefit Plans and proceedings with respect to qualified domestic relations
orders), suits or proceedings against or involving any Business Plan or
asserting any rights or claims to benefits under any Business Plan, or, to

suits, proceedings or investigations that would not reasonably be expected to
result in material liability.

to which SRT or Seller or any ERISA Affiliate contributes or contributed or is
or was obligated to contribute for the benefit of employees of the Business at
any time since January 1, 1994. Neither SRT nor Seller nor any ERISA Affiliate
has withdrawn from any multiemployer plan in a complete or partial withdrawal
which has resulted in any withdrawal liability which has not been satisfied in
full. All required contributions to any such multiemployer plan have been made
in full.

                 (e)      There are no unfunded obligations under any Business
Plan, other than an Employee Benefit Plan intended to be qualified under Section
401(a) of the Code, providing welfare benefits after termination of employment
to any employee of the Business (or to any beneficiary of any such employee),
excluding continuation of health coverage required to be continued under Section
4980B of the Code or other applicable laws.

exists with respect to any Business Plan at any time maintained or contributed
to by SRT or Seller, any of its Affiliates or any ERISA Affiliate that would
subject SRT or Seller or any ERISA Affiliate to any material fine, penalty, Tax
or liability of any kind imposed


                                      -39-

terminated at any time by Seller or SRT without any liability or cost (other
than those associated with benefits accrued through the date of termination or
amendment and other than those related to such amendment or termination), and,
except as set forth in the Disclosure Schedule, the assets of each Business Plan
may be converted at any time to cash without incurring or giving rise to any
market rate adjustment, surrender fee or other liability or cost.

6.3      CLAIMS FOR INDEMNIFICATION.

                 (a)      THIRD-PARTY CLAIMS. All claims for indemnification
made under this Agreement resulting from, related to or arising out of a
third-party claim against an Indemnified Party (as defined below) shall be made
in accordance with the following procedures. A person entitled to
indemnification under this Article VI (an "INDEMNIFIED PARTY") shall give prompt
written notification to the person from whom indemnification is sought (the
"INDEMNIFYING PARTY") of the commencement of any action, suit or proceeding
relating to a third-party claim for which indemnification may be sought or, if
earlier, upon the assertion in writing of any such claim by a third party. No
delay on the part of the Indemnified Party in notifying the Indemnifying Party
shall relieve the Indemnifying Party from any liability or obligation hereunder
except to the extent of any Damages caused by or arising out of such delay.
Within 30 days after delivery of such notification, the Indemnifying Party may,
at its expense, upon written notice thereof to the Indemnified Party, assume
control of the defense of such action, suit, proceeding or claim with counsel
reasonably satisfactory to the Indemnified Party. If the Indemnifying Party does
not assume control of such defense, the Indemnified Party shall control such
defense. The Party not controlling such defense may participate therein at its
own expense; provided that if the Indemnifying Party assumes control of such
defense and the Indemnified Party reasonably concludes, based on advice from
counsel, that the Indemnifying Party and the Indemnified Party have conflicting
interests with respect to such action, suit, proceeding or claim, the reasonable
fees and expenses of counsel to the Indemnified Party solely in connection
therewith shall be considered "DAMAGES" for purposes of this Agreement;
provided, however, that in no event shall the Indemnifying Party be


                                      -53-
<PAGE>


responsible for the fees and expenses of more than one counsel for all
Indemnified Parties. The Party controlling such defense shall keep the other
Party advised of the status of such action, suit, proceeding or claim and the
defense thereof and shall consider recommendations made by the other Party with
respect thereto. The Indemnified Party shall not agree to any settlement of such
action, suit, proceeding or claim without the prior written consent of the
Indemnifying Party. The Indemnifying Party shall not agree to any settlement of
such action, suit, proceeding or claim that does not include a complete release
of the Indemnified Party from all liability with respect thereto or that imposes
any liability or obligation on the Indemnified Party without the prior written
consent of the Indemnified Party, which shall not be unreasonably withheld,
conditioned or delayed.

                 (b)      PROCEDURE FOR OTHER CLAIMS. An Indemnified Party
wishing to assert a claim for indemnification under this Article VI which is not
subject to Section 6.3(a) shall deliver to the Indemnifying Party a written
notice (a "CLAIM NOTICE") which contains (i) a description and the amount (the
"CLAIMED AMOUNT") of any Damages incurred by the Indemnified Party (to the
extent that such Damages can be accurately quantified at the time of the claim),
(ii) a statement that the Indemnified Party is entitled to indemnification under
this Article VI and a reasonable explanation of the basis therefor, and (iii) a
demand for payment in the amount of such Damages. Within 30 days after delivery
of a Claim Notice, the Indemnifying Party shall deliver to the Indemnified Party
a written response in which the Indemnifying Party shall: (I) agree that the
Indemnified Party is entitled to receive all of the Claimed Amount (in which
case such response shall be accompanied by a payment by the Indemnifying Party
to the Indemnified Party of the Claimed Amount, by check or by wire


                                      -54-
<PAGE>


transfer), (II) agree that the Indemnified Party is entitled to receive part,
but not all of the Claimed Amount the "AGREED AMOUNT") (in which case such
response shall be accompanied by a payment by the Indemnifying Party to the
Indemnified Party of the Agreed Amount, by check or by wire transfer), or
(III) contest that the Indemnified Party is entitled to receive any of the
Claimed Amount. If the Indemnifying Party in such response contests the
payment of all or part of the Claimed Amount, the Indemnifying Party and the
Indemnified Party shall use good faith efforts to resolve such dispute. If
such dispute is not resolved within 60 days following the delivery by the
Indemnifying Party of such response, the Indemnifying Party and the
Indemnified Party shall each have the right to submit such dispute to a court
of competent jurisdiction in accordance with the provisions of Section 11.14.

6.4 SURVIVAL.

                 (a)      The representations and warranties of Seller and Buyer
set forth in this Agreement shall survive the Closing and the consummation of
the transactions contemplated hereby and continue until the fifteen-month

Notwithstanding the foregoing, (i) the representations and warranties of Seller

time they shall expire.

                 (b)      Any valid claim that is properly asserted in writing
pursuant to Section 6.3 prior to the expiration as provided in Section 6.4(a) of
the representation or warranty that is the basis for such claim shall survive
until such claim is finally resolved and satisfied.

6.5 LIMITATIONS.

                 (a)      Except with respect to claims (i) based on actual
fraud or (ii) made pursuant to Section 6.2(b) or Article IX, the rights of the

remedies of the Indemnified Parties and their respective Affiliates with respect
to claims resulting from or relating to any misrepresentation, breach of
warranty or failure to perform any covenant or agreement contained in this
Agreement or otherwise relating to the transactions that are the subject of this
Agreement. Without limiting the generality of the foregoing sentence, in no
event shall Buyer, its successors or permitted assigns be entitled to claim or
seek rescission of the transactions consummated under this Agreement.

                 (b)      Notwithstanding anything to the contrary contained in
this Agreement, each of the following six limitations shall apply:

Section 6.1 which exceeds $600,000 (it being understood that Seller shall not be
liable, in any event, for the first $600,000 of said Damages), except in the
case of any Damages resulting from, relating to or constituting any
misrepresentation or breach of warranty by Seller with respect to Section 2.9,
Article IX and the first sentence of Section 2.2(b);

                           (iv)     the amount of any Damages for which

SRT and Nicolet as of January 1, 2000 or a related accrual or reserve created
thereafter in the Ordinary Course of Business;

                           (v)      Seller shall not be liable for any Damages

that causes such misrepresentation or breach of warranty comes to Buyer's
attention in the Ordinary Course of Business or is brought to Buyer's attention
by a Governmental Entity (other than as a result of a voluntary disclosure by
Buyer that is not required by Environmental Law or made in response to an
inquiry by a Governmental Entity); and

                           (vi)     Seller shall not be liable for any Damages
under this Article VI resulting from, relating to or constituting any
misrepresentation or breach of warranty in clauses (i) and (ii) of Section
2.17(c) unless (A) in the case of clause (i) of Section 2.17(c), either such
claim that causes such misrepresentation or breach of warranty comes to Buyer's
attention from a third party (other than an Affiliate of Buyer and other than as
a result of a voluntary disclosure by Buyer that is not required by
Environmental Law or made in response to an inquiry by a Governmental Entity) or
the environmental condition of the property referred to in clause (i) of Section

such that the investigation or remediation of a Release of Materials of
Environmental Concern is required by applicable Environmental Law or (B) in the
case of clause (ii) of Section 2.17(c), the claim that causes such

together with all other Damages for which Seller may be liable under this
Agreement, shall not exceed the Purchase Price, or (B) (I) a claim described in
paragraphs (b)

                                      -58-

responsible and liable for any Damages or other amounts under this Article VI
that are consequential, in the nature of lost profits, diminution in value,
damage to reputation or the like, special or punitive or otherwise not actual
Damages; PROVIDED, HOWEVER, that this sentence shall not limit an Indemnifying
Party's obligations to indemnify the Indemnified Party for any Damages owed or
paid to a third party that are consequential, in the nature of lost profits,

Damages, in each case only to the extent otherwise required pursuant this

efforts to minimize the Damages for which indemnification is provided to Buyer
by Seller under this Article VI.

                  (d)      Seller shall not have any right of contribution
against the Business with respect to any breach by Seller of any of its
representations, warranties, covenants or agreements. Effective as of the

                  (e)      The amount of any Damages for which indemnification
is provided under this Article VI shall be reduced by any related recoveries to
which the


                                      -59-
<PAGE>

Indemnified Party is entitled under insurance policies or other related payments

                  (a)      Seller shall be responsible for the preparation and
filing of all Tax Returns for Seller for all periods as to which Tax Returns are
due after the Closing Date (including the consolidated, unitary, and combined
Tax Returns for Seller which include the operations of the Business for any
period ending on or before the Closing Date) and for all Tax


                                      -60-
<PAGE>

Returns of SRT for all taxable periods that end on or before the Closing Date.
Such Tax Returns shall be prepared in a manner consistent with the last previous
Tax Returns. Seller shall make or cause to be made all payments required with
respect to any such Tax Returns except to the extent provided in Sections 1.4(b)
and 1.4(d) hereof. Buyer shall promptly reimburse Seller for the amount of any
such Taxes paid by Seller (i) to the extent such Taxes are attributable (as
determined under Section 9.2 hereof) to periods following the Closing Date and
(ii) to the extent of any reserves for Taxes on the Most Recent Balance Sheet
reduced by any subsequent payments of Taxes reflected in such reserves through
the Closing Date and increased by the amount of any subsequent increases in such

Business in the Ordinary Course of Business following the date of the Most
Recent Balance Sheet through the Closing Date (as so adjusted, "TAX RESERVES").

such portion of the payment exceeds the amount of the Tax Reserves.

                  (c)      Any Tax Return to be prepared and filed for taxable
periods beginning before the Closing Date and ending after the Closing Date
shall be prepared on a basis consistent with the last previous Tax Return, and
Buyer shall consult with Seller concerning each such Tax Return and report all
items with respect to the period ending on the


                                      -61-

that if Buyer is advised by counsel that the filing of any Tax Return and the
reporting on such Tax Return of any item in accordance with the instructions of
Seller may subject Buyer to any penalties or fines, Buyer may file such Tax
Return without regard to Seller's instructions relating to such item. Buyer
shall provide Seller with a copy of each proposed Tax Return (and such
additional information regarding such Tax Return as may reasonably be requested
by Seller) at least 20 days prior to the filing of such Tax Return.

                  (d)      Buyer shall be responsible for the payment of any
transfer, sales, use, stamp, conveyance, value added, recording, registration,
documentary, filing and other non-income Taxes arising in connection with the
consummation of the transactions contemplated by this Agreement.

                  (e)      Buyer shall be responsible for the payment of any and
all Taxes not incurred in the ordinary course of business attributable to the
acts or omissions of Buyer or Buyer's Affiliates occurring after the Closing on
the Closing Date.

9.2      ALLOCATION OF CERTAIN TAXES.

                  (a)      Buyer and Seller agree that if Seller or SRT is
permitted but not required under applicable foreign, state or local Tax laws to
treat the Closing Date as the last day of a taxable period, Buyer and Seller
shall treat such day as the last day of a taxable period. Buyer and Seller agree
that they will treat the Business as if it ceased to be part of the affiliated
group of corporations of which Seller is a member within the meaning of Section
1504 of the Code, and any comparable or similar provision of state, local or
foreign laws or regulations, as of the close of business on the Closing Date.

<PAGE>

                  (b)      Any Taxes for a taxable period beginning before the
Closing Date and ending after the Closing Date with respect to the Business
shall be paid by Buyer, and the Taxes for such period shall be apportioned for
purposes of Section 9.1 between Seller and Buyer based on the actual operations
of the Business during the portion of such period ending on the Closing Date and
the portion of such period beginning on the day following the Closing Date, and
for purposes of the provisions of Section 9.1 and 9.3, each portion of such
period shall be deemed to be a taxable period (whether or not it is in fact a
taxable period); PROVIDED, HOWEVER, that in the case of any Tax that is assessed
on a periodic basis, (i) Seller shall be apportioned an amount of such Tax equal
to the aggregate amount of such Tax for the entire period multiplied by a
fraction, the numerator of which is the number of days in the portion of the
Taxable period that ends on the Closing Date and the denominator of which is the
total number of days in the Taxable period, and (ii) Buyer shall be apportioned
the balance of such Tax.

9.3      REFUNDS AND CARRYBACKS.

                  (a)      Seller shall be entitled to any refunds (including
any interest paid thereon) or credits of Taxes attributable to taxable periods
ending (or deemed pursuant to Section 9.2(b) to end) on or before the Closing
Date.

                  (b)      Buyer and/or its Affiliates, as the case may be,
shall be entitled to any refunds (including any interest paid thereon) or
credits of Taxes attributable to taxable periods beginning (or deemed pursuant
to Section 9.2(b) to begin) after the Closing Date.

                  (c)      Buyer shall forward to or reimburse Seller for any
refunds (including any interest paid thereon) or credits due Seller after
receipt thereof, and Seller shall


                                      -63-
<PAGE>

promptly forward to Buyer or reimburse Buyer for any refunds (including any
interest paid thereon) or credits due Buyer after receipt thereof.

                  (d)      Buyer and Seller agree that, with respect to any Tax,
SRT shall not carry back any item of loss, deduction or credit which arises in
any taxable period ending after the Closing Date to any taxable period ending on
or before the Closing Date.

9.4      COOPERATION ON TAX MATTERS; TAX AUDITS.

                  (a)      Buyer and Seller and their respective Affiliates
shall cooperate in the preparation of all Tax Returns for any Tax periods for
which one Party could reasonably require the assistance of the other Party in
obtaining any necessary information. Such cooperation shall include, but not be
limited to, furnishing prior years' Tax Returns or return preparation packages
to the extent related to the Business illustrating previous reporting practices
or containing historical information relevant to the preparation of such Tax
Returns, and furnishing such other information within such Party's possession
requested by the Party filing such Tax Returns as is relevant to their
preparation. Such cooperation and information also shall include without
limitation provision of powers of attorney for the purpose of signing Tax
Returns and defending audits and promptly forwarding copies of appropriate
notices and forms or other communications received from or sent to any
applicable governmental authority responsible for the imposition of Taxes (the
"Taxing Authority") which relate to the Business, and providing copies of all
relevant Tax Returns to the extent related to the Business, together with
accompanying schedules and related workpapers, documents relating to rulings or
other determinations by any Taxing Authority and records concerning the
ownership and Tax basis of property, which the requested Party may possess.
Buyer and Seller and their respective Affiliates shall make their respective
employees and facilities available on a mutually convenient basis to explain any
documents or information provided hereunder.

                  (b)      Seller shall have the right, at its own expense, to
control any audit or examination by any Taxing Authority ("Tax Audit"), initiate
any claim for refund, contest, resolve and defend against any assessment, notice
of deficiency, or other adjustment or


                                      -65-
<PAGE>

proposed adjustment relating to any and all Taxes for any taxable period ending
on or before the Closing Date with respect to the Business. Buyer shall have the
right, at its own expense, to control any other Tax Audit, initiate any other
claim for refund, and contest, resolve and defend against any other assessment,
notice of deficiency, or other adjustment or proposed adjustment relating to
Taxes with respect to the Business, including a potential liability for Taxes in
taxable periods ending after the Closing Date as a result of a compromise,
contest or concession by Seller in a taxable period prior to the Closing Date;
provided that, with respect to (i) any state, local or foreign Taxes for any
taxable period beginning before the Closing Date and ending after the Closing
Date and (ii) any item the adjustment of which may cause Seller to become
obligated to make any payment pursuant to Section 9.1(a) hereof, Buyer shall
consult with Seller with respect to the resolution of any issue that would
affect Seller, and not settle any such issue, or file any amended Tax Return
relating to such issue, without the consent of Seller, which consent shall not
be unreasonably withheld. Where consent to a settlement is withheld by Seller
pursuant to this Section, Seller may continue or initiate any further
proceedings at its own expense, provided that any liability of Buyer, after
giving effect to this Agreement, shall not exceed the liability that would have
resulted had Seller not withheld its consent.

9.5      TERMINATION OF TAX SHARING AGREEMENTS. All Tax sharing agreements or
similar arrangements with respect to or involving the Business shall be
terminated prior to the Closing Date and, after the Closing Date, Buyer and its
Affiliates shall not be bound thereby or have any liability thereunder for
amounts due in respect of periods ending on or before the Closing Date.

                               FURTHER AGREEMENTS

10.1     ACCESS; RECORD RETENTION; COOPERATION.

                  (a)      ACCESS. Subject to compliance with applicable laws
and regulations regarding classified information and security clearance,
following the Closing, each Party shall afford to the other Party and to the
other Party's Affiliates, authorized accountants and counsel reasonable access
(including using reasonable efforts to give access to third parties possessing
information and providing reasonable access to its own employees who are in
possession of relevant information) and duplicating rights during normal
business hours in a manner so as to not unreasonably interfere with the conduct
of business to (a) all non-privileged and non-trade secret records, books,
contracts, instruments, documents, correspondence, computer data and other data
and information (collectively, "INFORMATION") within the possession or control
of such Party or its Affiliates and (b) as reasonably necessary, the other
party's personnel, in each case under clauses (a) or (b) relating to the
Business prior to the Closing, insofar as such access is reasonably required by
the other Party in connection with the requesting party's obligations under this
Agreement or with respect to the Business. Information may be requested under
this Section 10.1(a) for, without limitation, financial reporting and accounting
matters, preparing financial statements, preparing and filing of any Tax
Returns, prosecuting any claims for refund, defending any Tax claims or
assessment, preparing securities law or exchange filings, prosecuting, defending
or settling any litigation, Environmental Matter or insurance claim, performing
this Agreement and the transactions contemplated hereby, and all other proper
business purposes. Each Party's obligations under


                                      -67-
<PAGE>

this Section 10.1(a) shall continue for such period of time as is required by
law for records to be maintained with respect to the subject matter of the
request by the Party requesting access, but in any event for a period of two
years after the Closing Date.

                  (b)      REIMBURSEMENT. A Party providing Information or
personnel to another Party under Section 10.1(a) shall be entitled to receive
from the recipient, upon the presentation of invoices therefor, payments for
such amounts, relating to supplies, disbursements and other out-of-pocket
expenses, as may reasonably be incurred in providing such Information; PROVIDED,
HOWEVER, that no such reimbursements shall be required for the salary or cost of
fringe benefits or similar expenses pertaining to employees or directors of the
providing Party or its Affiliates.

                  (c)      RETENTION OF RECORDS. Except as otherwise agreed to
in writing by the Parties, each Party shall (and shall cause its Affiliates to)
use reasonable efforts to preserve all Information in its possession pertaining
to the Business prior to the Closing for such period of time as is required by
law for such Information to be maintained, but in any event for at least two
years after the Closing Date. Notwithstanding the foregoing, in lieu of
retaining any specific Information, any Party may offer in writing to the other
Party to deliver such Information to the other Party and, if such offer is not
accepted within 90 days, the offered Information may be disposed of at any time.

                  (d)      PREPARATION OF SELLER FINANCIAL STATEMENTS. Following
the Closing, Buyer shall cause the Business to provide to Seller and its
Affiliates all information relating to the Business reasonably required for
Seller and its Affiliates to prepare the financial statements of Seller and its
Affiliates for all fiscal periods within the fiscal year ending


                                      -68-
<PAGE>

December 30, 2000. During the period of preparation of the audited accounts of
Seller, Buyer shall use commercially reasonable efforts to ensure that Seller
and its Affiliates (and their auditors) will be provided with reasonable access
to the Business, its financial management, including the financial directors of
each Business and any accountant's work papers, and their books, accounts and
records and will be able to review the work being carried out in accordance with
this Section.

                  (e)      CONFIDENTIALITY. Each of Buyer and Seller shall hold,
shall cause its direct and indirect majority-owned subsidiaries to hold, and
shall use reasonable efforts to cause its consultants and advisors to hold, in
strict confidence all Information concerning the other furnished to it by the
other Party or the other Party's representatives pursuant to this Section 10.1
(except to the extent that such Information (i) is or becomes generally
available to the public other than as a result of a disclosure by the receiving
Party in violation of the terms of this Section 10.1, (ii) was within the
possession of the receiving Party prior to it being furnished to the receiving
Party by or on behalf of the other Party pursuant hereto, provided that the
source of such information was not known by the receiving Party at the time of
receipt to be bound by a confidentiality agreement with or other contractual,
legal or fiduciary obligation of confidentiality to the other Party or any other
party with respect to such information, (iii) is or becomes available to the
receiving Party from a source other than the other Party, provided that such
source is not, to the knowledge of the receiving Party at the time of receipt,
bound by a confidentiality agreement with or other contractual, legal or
fiduciary obligation of confidentiality to the other Party or any other party
with respect to such information, or (iv) was or is independently developed by
the receiving Party without utilizing


                                      -69-
<PAGE>

any Information or violating any of the receiving Party's obligations under this
Agreement), and each Party shall not release or disclose such Information to any
other person, except its auditors, attorneys, financial advisors, bankers and
other consultants and advisors, unless compelled to disclose such Information by
judicial or administrative process or by other requirements of law or so as not
to violate the rules of any stock exchange; PROVIDED, HOWEVER, that in the case
of disclosure compelled by judicial or administrative process, the disclosing
Party shall (to the extent permitted by applicable law) notify the
non-disclosing party promptly of the request or requirement so that the
non-disclosing party may seek an appropriate protective order or waive
compliance with the provisions of this Section 10.1(e). If, in the absence of a
protective order or the receipt of a waiver hereunder, a Party is compelled to
disclose any Information by judicial or administrative process, such Party may
so disclose the Information; provided, however, that, at the written request of
the non-disclosing Party, the disclosing party shall use commercially reasonable
efforts to obtain, at the expense of the non-disclosing Party, an order or other
assurance that confidential treatment will be accorded to such portion of the
Information required to be disclosed. Seller shall not disclose any Information
to any of its Affiliates that is not a direct or indirect majority-owned
subsidiary of Seller unless such Affiliate shall agree to keep such Information
confidential in accordance with the provisions of this Section 10.1(e).

10.2     DIRECTOR AND OFFICER INDEMNIFICATION. Buyer shall not take any action
to alter or impair any exculpatory or indemnification provisions, now existing
in the charter or bylaws of SRT, for the benefit of any individual who served as
a director or officer of SRT at any time prior to the Closing Date, except for
any changes that may be required to conform with changes in


                                      -70-
<PAGE>

applicable law and any changes that do not affect the application of such
provisions to acts or omissions of such individuals prior to the Closing Date.


10.3     COVENANT NOT TO COMPETE. During the period commencing on the Closing
Date and continuing until the third anniversary of the Closing Date (the
"NONCOMPETITION PERIOD"), Seller shall not (and shall cause each Noncompetition
Party (as defined below) not to), directly or indirectly own, manage, operate or
control any business in competition with the business activities conducted by
the Business on the Closing Date (a "COMPETITIVE BUSINESS"); provided, however,
that the foregoing covenants shall not prohibit, or be interpreted as
prohibiting, any Noncompetition Party from:

                  (a)      continuing anywhere in the world in any type of
business conducted by any Noncompetition Party on the date hereof, which is not
part of the Business (Seller hereby acknowledging that, on the date hereof, it
conducts no Competitive Business anywhere in the world);

                  (b)      entering into any relationship with a person or
entity not owned, managed, operated or controlled by any Noncompetition Party
for purposes primarily unrelated to a Competitive Business;

                  (c)      making equity investments in publicly owned companies
which conduct a Competitive Business, provided such investments do not result in
ownership of more than 5% of any such Competitive Business by any Noncompetition
Party; or

                  (d)      acquiring any person or entity which conducts a
Competitive Business if either:


                                      -71-
<PAGE>

                           (i)      in the calendar year prior to such
acquisition, the revenues of such person or entity from its Competitive Business
do not constitute more than 15% of the total revenues of such person or entity;
or

                           (ii)     the applicable Noncompetition Party promptly
commences and thereafter completes the total divestiture of such Competitive
Business not later than 12 months after such acquisition. For purposes of the
Agreement, "NONCOMPETITION PARTY" means each of Seller and any direct or
indirect majority-owned subsidiaries of Seller while (but only while) such
entity is a direct or indirect majority-owned subsidiary of Seller. Seller shall
use reasonable efforts to cause each of its Affiliates to be bound by the
provisions of this Section 10.3 as if it were a Noncompetition Party for so long
as such Affiliate remains an Affiliate of Seller.

10.4     NON-SOLICITATION. During the Noncompetition Period, without the prior
written consent of Buyer, Seller shall not (and shall cause each Noncompetition
Party not to), directly or indirectly, solicit for the purpose of employment any
person who was employed by the Business on the Closing Date and who continues to
be so employed immediately preceding such solicitation; PROVIDED, HOWEVER, that
the foregoing shall not prohibit Seller or any of its Affiliates from placing
any general advertisements for employees so long as such general advertisements
are not expressly directed to any employees of the Business or from hiring or
engaging any employee in response thereto or from hiring any person who
initiates, directly or indirectly, discussions with Seller or any of its
Affiliates regarding potential employment.

10.5     DISCLOSURE GENERALLY. Any information furnished in the Disclosure
Schedule shall be deemed to modify all of Seller's representations and
warranties. The inclusion of any


                                      -72-
<PAGE>

information in the Disclosure Schedule shall not be deemed to be an admission or
acknowledgment, in and of itself, that such information is required by the terms
hereof to be disclosed, is material to the Business, has or would have a
Business Material Adverse Effect, or is outside the Ordinary Course of Business.
For purposes of this Agreement, the terms "to Seller's knowledge," "known by
Seller" or other words of similar meaning shall mean the actual knowledge of (i)
Barry Howe, Ronald Lindell, Bruce Johnson and Fred Schlieper, (ii) solely with
respect to SRT's Business, James Costa, and (iii) solely with respect to
Nicolet's Business, Richard Daly, in each case without any obligation of
investigation, and shall not refer to the knowledge of any other person or
entity.

10.6     ACKNOWLEDGMENTS BY BUYER. Buyer acknowledges that it has conducted to
its satisfaction an independent investigation and verification of the financial
condition, results of operations, assets, liabilities, properties and projected
operations of the Business and, in making its determination to proceed with the
transactions contemplated by this Agreement, Buyer has relied on the results of
its own independent investigation and the representations and warranties of
Seller expressly and specifically set forth in Article II of this Agreement,
including the Disclosure Schedules. SUCH REPRESENTATIONS AND WARRANTIES BY
SELLER CONSTITUTE THE SOLE AND EXCLUSIVE REPRESENTATIONS AND WARRANTIES OF
SELLER TO BUYER IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY, AND
BUYER UNDERSTANDS, ACKNOWLEDGES AND AGREES THAT ALL OTHER REPRESENTATIONS AND
WARRANTIES OF ANY KIND OR NATURE WHETHER EXPRESS, IMPLIED OR STATUTORY
(INCLUDING, BUT NOT LIMITED TO, ANY RELATING TO THE FUTURE OR HISTORICAL
FINANCIAL


                                      -73-
<PAGE>

CONDITION, RESULTS OF OPERATIONS, ASSETS OR LIABILITIES OF THE BUSINESS AND ANY
SET FORTH IN THE CONFIDENTIAL OFFERING MEMORANDUM PREVIOUSLY DELIVERED TO BUYER)
ARE SPECIFICALLY DISCLAIMED BY SELLER. BUYER ALSO ACKNOWLEDGES THAT, EXCEPT IN
THE CASE OF ACTUAL FRAUD, ITS SOLE AND EXCLUSIVE RECOURSE IN RESPECT OF THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT IS TO ASSERT RIGHTS OF BUYER
PURSUANT TO ARTICLE VI AND ARTICLE IX.

10.7     CERTAIN INSURANCE MATTERS. Seller shall maintain, and shall not take
any steps to prospectively or retrospectively cancel, buy-out or remove the
Business or Seller as an additional named insured from, any and all Business
Policies providing coverage for all periods prior to the Closing with respect
to any events, occurrences or matters occurring prior to the Closing (the
"OCCURRENCE-BASED BUSINESS POLICIES") (subject in each case to the
deductibles, limits and other terms and conditions of such policies). Buyer
shall be entitled to the benefit of, and Seller shall pay to Buyer, any
amounts and/or recoveries received by Seller under any Occurrence-Based
Business Policies in respect of any Assumed Liabilities (subject to the
deductibles, limits and other terms and conditions of such policies).

                                      -74-
<PAGE>

10.8     CERTAIN EMPLOYEE BENEFITS MATTERS.

                  (a)      PRE-CLOSING CONDUCT; OTHER LIABILITIES. Neither
Seller nor SRT shall be under any obligation solely by reason of this Agreement
to terminate the employment of any employee of SRT (an "SRT EMPLOYEE") or of
Seller engaged in Nicolet's Business (a "NICOLET EMPLOYEE" and, together with an
SRT Employee, a "BUSINESS EMPLOYEE") prior to the Closing Date. Buyer shall be
liable for any amounts to which any Business Employee becomes entitled, as a
result of, or in connection with, (i) the employment by Buyer of any Business
Employee on or after the Closing Date and (ii) the termination by Buyer of
employment of any Business Employee on or after the Closing Date.

                  (b)      OFFER OF EMPLOYMENT; CONTINUATION OF EMPLOYMENT. The
Parties hereto intend that there shall be continuity of employment with respect
to all Business Employees. Buyer shall offer employment commencing on the
Closing Date to all Nicolet Employees, including those on vacation, leave of
absence, disability or layoff, on the terms set forth in Section 10.8(d). Buyer
will give credit for past service of the Business Employees with Seller or SRT
for purposes of participation under Buyer's standard benefit plans (to the
extent that past service is relevant to participation in such plans) and for
purposes of determining such employee's vested interest under such plans. Those
persons who accept Buyer's offer of employment and who commence working with
Buyer on the Closing Date shall hereafter be referred to, with respect to their
period of employment by Buyer, as "TRANSFERRED EMPLOYEES."

                  (c)      401(k) PLAN TRANSFER. As soon as practicable after
the Closing Date, Seller shall cause the transfer of (i) the account balances of
the current and former Nicolet Employees who participate under the Nicolet
Instruments Corporation Savings (401(k)) Plan


                                      -75-
<PAGE>

(the "SELLER'S 401(k) PLAN"), including outstanding loans of such persons and
(ii) assets having a value equal to said account balances to a profit-sharing
plan maintained by Buyer which is qualified under Section 401(a) of the Code and
which includes a cash or deferred arrangement which qualifies under Section
401(k) of the Code (the "BUYER'S 401(k) PLAN"), such balances and assets being
referred to hereinafter as the "TRANSFERRED 401(k) ACCOUNTS." Buyer shall, prior
to the Closing, notify Seller in writing of the identity of Buyer's 401(k) Plan
and shall cause Buyer's 401(k) Plan to accept the transfers referred to in the
prior sentence. The assets transferred shall consist of the assets allocated
under Seller's 401(k) Plan to the accounts of current and former Nicolet
Employees, including promissory notes evidencing outstanding loans of such
persons. From and after the above-referenced account transfers, Buyer shall
assume all responsibility for the management and administration of the
Transferred 401(k) Accounts and Seller shall have no further obligations with
respect thereto.

                  (d)      COMPENSATION; EMPLOYEE BENEFITS; SEVERANCE PLANS. The
Business Employees shall cease to participate in and to accrue further benefits
under the Business Plans immediately prior to the Closing Date and Seller or SRT
shall arrange for any amendments, notices and filings necessary in connection
with such cessation. On the Closing Date, Buyer shall provide each Transferred
Employee and each SRT Employee who continues his or her employment with SRT or
Buyer after the Closing Date with (i) the opportunity to participate in Buyer's
standard benefit arrangements (including without limitation bonus arrangements)
("BUYER'S PLAN") in accordance with paragraph (b) above and (ii) salaries that
are not less than pre-closing salaries for such employees.


                                      -76-
<PAGE>

                  (e)      WELFARE PLANS. With respect to any Buyer Plan that is
a "welfare benefit plan" (as defined in Section 3(1) of ERISA) or any Buyer Plan
that would be a "welfare benefit plan" (as defined in Section 3(1) of ERISA) if
it were subject to ERISA, Buyer shall, with respect to each Transferred Employee
and SRT Employee, (i) cause to be waived any pre-existing condition limitations
that affect such employees or their beneficiaries, (ii) give effect, in
determining any deductible and maximum out-of-pocket limitations, to claims
incurred and amounts paid by, and amounts reimbursed to, such employees with
respect to similar plans maintained by Seller or SRT immediately prior to the
Closing Date and (iii) recognize all credited service for purposes of
eligibility and vesting and level of benefits (but not for purposes of benefit
accrual except to the extent otherwise provided under the terms of the plan) to
the same extent such service was recognized under similar plans maintained by
Seller or SRT immediately prior to the Closing Date. Buyer shall make
appropriate arrangements to allow the use by Transferred Employees and SRT
Employees of any accrued benefits under any cafeteria plan (as defined in
Section 125 of the Code) which was maintained by Seller or any of its Affiliates
for such Transferred Employees or SRT Employees.

                  (f)      ACCRUED SICK TIME; VACATION. All accrued but unused
sick time to which any Transferred Employee or SRT Employee is entitled pursuant
to the sick policies applicable to such Transferred Employee or SRT Employee
immediately prior to the Closing Date (the "SICK POLICIES") shall be forfeited,
and each Transferred Employee and SRT Employee shall thereafter accrue sick time
pursuant to Buyer's sick time policies; PROVIDED that such forfeiture does not
give rise to liability, and PROVIDED FURTHER that if any such liability does
arise, then in lieu of the foregoing, Buyer shall assume the liability for
allowing each


                                      -77-
<PAGE>

Transferred Employee and SRT Employee with any accrued but unused sick time
referred to above to use such sick time on or prior to December 31, 2000, at
which date all such remaining time shall be forfeited and prior to such date
Buyer shall not place unreasonable restrictions on the ability of any such
Transferred Employee or SRT Employee to use such accrued sick time. Buyer shall
promptly reimburse Seller for the entire cost that Seller incurs in connection
with the satisfaction of vacation liabilities (including without limitation,
vacation liabilities for SRT Employees) that become due and payable as a result
of the transactions contemplated by this Agreement. Notwithstanding any other
provision of this Agreement, no Transferred Employee or SRT Employee with
respect to whom vacation liability has been paid by Seller under the preceding
sentence or by Buyer after the Closing shall accrue vacation leave under Buyer's
policies based on service prior to the Closing; PROVIDED, HOWEVER, that the
foregoing shall not be deemed to limit Buyer's obligations under the penultimate
sentence in Section 10.8(b).

                  (g)      U.S. WARN ACT. Buyer agrees to provide to any
Transferred Employee or SRT Employee any required notice under the Worker
Adjustment and Retraining Notification Act ("WARN") and any other applicable law
and to otherwise comply with any such statute with respect to any "plant
closing" or "mass layoff' (as defined in WARN) or similar event affecting
Transferred Employees or SRT Employees and occurring on or after the Closing
Date or arising as a result of the transactions contemplated hereby. Buyer shall
indemnify and hold harmless Seller and its Affiliates with respect to any
liability relating to Transferred Employees or SRT Employees under WARN or other
applicable law arising from the actions (or inactions) of Buyer or its
Affiliates on or after the Closing Date or arising as a result of the
transactions contemplated hereby.

<PAGE>

                  (h)      U.S. COBRA. Buyer agrees to provide any required
notice under the Consolidated Omnibus Budget Reconciliation Act of 1986
("COBRA") and any other applicable law on or after the Closing Date relating to
Transferred Employees or SRT Employees. Buyer shall indemnify and hold harmless
Seller and its Affiliates with respect to any liability under COBRA or other
applicable law relating to Transferred Employees or SRT Employees arising from
the actions (or inactions) of Buyer or its Affiliates on or after the Closing
Date or arising as a result of the transactions contemplated hereby.

10.9     RESIGNATIONS. Effective upon the Closing, Seller shall cause all of
its own employees, directors and attorneys and all of its Affiliates' (other
than SRT) employees, directors and attorneys to resign from the board of
directors of SRT and from all positions as executive officers of SRT.

10.10    FURTHER ASSURANCES. At any time and from time to time after the
Closing, as and when requested by a Party hereto and at such Party's expense,
the other Party shall promptly execute and deliver, or cause to be executed and
delivered, all such documents and instruments and shall take, or cause to be
taken, all such further or other actions as such other Party may reasonably
request to evidence and effectuate the transactions contemplated by this
Agreement. Upon the request of Seller, Buyer shall arrange for replacement
arrangements (which shall include a full and complete release of Seller and its
Affiliates (other than SRT)), including, to the extent required, guarantees and
letters of comfort, reasonably satisfactory to Seller with respect to all
letters of credit and other borrowings of the Business which are subject to any
guarantee, covenant, indemnity, letter of comfort or similar assurance provided
by Seller or any of its Affiliates (other than SRT) as of the Closing Date.

10.11    BANK ACCOUNT RECONCILIATION. Upon the written request of Buyer
accompanied by documentation in reasonable detail made no earlier than 30 days
after the Closing Date, Seller shall promptly reimburse Buyer for any and all
checks written on or before the Closing by any of Seller, Nicolet or SRT and
drawn on any Business Bank Account (other than the Business Payroll Accounts)
after the Closing.

10.12    FACILITY LEASES. Buyer shall not assign, amend or modify the Leases
with respect to the Facility in a manner that would in any way increase, or
adversely affect, Seller's liability thereunder without Seller's prior written
consent, which consent shall not be unreasonably withheld. The Parties agree
that, in connection with a request by Buyer for Seller's consent in connection
with such an assignment, amendment or modification of such a Lease, a
requirement by Seller to be released of all liability with respect to such Lease
shall not be unreasonable.

10.13    USE OF NAME FOR TRANSITION PERIOD. Seller hereby grants and Buyer
hereby accepts a royalty-free, worldwide exclusive right and license to use the
name "Nicolet Imaging Systems" for a period of two years after the Closing Date
in connection with the conduct by Buyer of Nicolet's Business, as Nicolet's
Business was conducted on the Closing Date, including without limitation the
grant of the non-exclusive right and license to use the name "Nicolet Imaging
Systems" to Buyer's distributors if necessary or useful for the promotion and
sale of products of Nicolet's Business. The license set forth in this Section
10.13 shall not (i) include any right to use the name "Nicolet" other than when
used by Buyer exclusively in the name "Nicolet Imaging Systems" or (ii) prohibit
Seller or any of its Affiliates from using during the term of the license the
name "Nicolet Imaging Systems" when describing their former affiliation with
Nicolet's Business. Buyer agrees that its use of the name "Nicolet Imaging
Systems" shall be


                                      -80-
<PAGE>

consistent with Seller's past practices in connection with Nicolet's Business
and, with respect to such use, Buyer shall adhere to substantially similar
quality standards to which Seller adhered immediately prior to the Closing. The
Parties agree that the grant of the license under this Section constitutes a
part of the consideration given by Seller in exchange for the Purchase Price.

                                   ARTICLE XI

                                  MISCELLANEOUS

11.1     PRESS RELEASES AND ANNOUNCEMENTS. No Party shall issue (and each Party
shall cause its Affiliates not to issue) any press release or public disclosure
relating to the subject matter of this Agreement without the prior written
approval of the other Party; PROVIDED, HOWEVER, that any Party may make any
public disclosure it believes in good faith is required by law, regulation or
stock exchange rule (in which case the disclosing Party shall advise the other
Party and the other Party shall have the right to review such press release or
announcement prior to its publication).

11.2     NO THIRD PARTY BENEFICIARIES. This Agreement shall not confer any
rights or remedies upon any person (including with respect to any employee or
former employee of Seller, Buyer or any of their Affiliates, any Transferred
Employees and any Business Employees, any right to employment or contractual
employment for any specified period) other than the Parties and their respective
successors and permitted assigns and, to the extent specified herein, their
respective Affiliates; PROVIDED, HOWEVER, that the provisions of Article VI and
Section 10.2 are intended for the benefit of the entities and individuals
specified therein and their respective legal representatives, successors and
assigns.

11.3     ACTION TO BE TAKEN BY AFFILIATES. The Parties shall cause their
respective Affiliates to comply with all of the obligations specified in this
Agreement to be performed by such Affiliates. Prior to the Closing, SRT will be
deemed to be an Affiliate of Seller and not of Buyer. Following the Closing, SRT
will be deemed to be an Affiliate of Buyer and not of Seller.

11.4     ENTIRE AGREEMENT. This Agreement (including the documents referred to
herein) and the Confidentiality Agreement, dated September 16, 1999, previously
entered into between Buyer and Seller (the "CONFIDENTIALITY AGREEMENT"), and
Section 1 (and no other provision) of the letter of intent, dated January 20,
2000, between Buyer and Seller (the "LETTER OF INTENT"), constitute the entire
agreement between Buyer, on the one hand, and Seller, on the other hand. This
Agreement supersedes any prior understandings, agreements, or representations by
or between Buyer, on the one hand, and Seller, on the other hand, whether
written or oral, with respect to the subject matter hereof (other than the
Confidentiality Agreement and Section 1 (and no other provision) of the Letter
of Intent).

11.5     SUCCESSION AND ASSIGNMENT. This Agreement shall be binding upon and
inure to the benefit of the Parties named herein and their respective successors
and permitted assigns. No Party may assign either this Agreement or any of its
rights, interests, or obligations hereunder without the prior written approval
of the other Party. Notwithstanding the foregoing, Buyer may, by prior written
notice to Seller, assign some or all of its rights, interests and/or obligations
hereunder (including under Section 1.1(a)) to one or more Affiliates of Buyer
(each, a "DESIGNATED TRANSFEREE"); provided that (i) as a condition of such
assignment the Designated Transferee agrees to be bound by the provisions of
this Agreement and (ii) no such assignment


                                      -82-
<PAGE>

shall relieve Buyer of any of its obligations hereunder. If Buyer so assigns any
of its rights, interests and/or obligations hereunder to one or more Designated
Transferees, unless the context otherwise requires, all references herein to
Buyer shall mean and include both Buyer and any and all such Designated
Transferees.

11.6     COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original but both of which
together shall constitute one and the same instrument.

11.7     HEADINGS. The section headings contained in this Agreement are inserted
for convenience only and shall not affect in any way the meaning or
interpretation of this Agreement.

11.8     NOTICES. All notices, requests, demands, claims and other
communications hereunder shall be in writing. Any notice, request, demand, claim
or other communication hereunder shall be deemed duly delivered one business day

Any Party may give any notice, request, demand, claim, or other communication
hereunder using any other means (including personal delivery, expedited courier,
messenger service, telex, ordinary mail, or electronic mail), but no such
notice, request, demand, claim or other communication shall be deemed to have

                                      -84-
<PAGE>

requests, demands, claims and other communications hereunder are to be delivered
by giving the other Parties notice in the manner herein set forth.

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

11.10    AMENDMENTS AND WAIVERS. The Parties may mutually amend or waive any
provision of this Agreement at any time. No amendment or waiver of any provision
of this Agreement shall be valid unless the same shall be in writing and signed
by both of the Parties. No waiver by either Party of any default,
misrepresentation, or breach of warranty or covenant hereunder, whether
intentional or not, shall be deemed to extend to any prior or subsequent
default, misrepresentation or breach of warranty or covenant hereunder or affect
in any way any rights arising by virtue of any prior or subsequent such
occurrence.

11.11    SEVERABILITY. Any term or provision of this Agreement that is invalid
or unenforceable in any situation in any jurisdiction shall not affect the
validity or enforceability of the remaining terms and provisions hereof or the
validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction. If the final judgment of a court of
competent jurisdiction declares that any term or provision hereof is invalid or
unenforceable, the Parties agree that the body making the determination of
invalidity or unenforceability shall have the power to reduce the scope,
duration or area of the term or provision, to delete specific words or phrases,
or to replace any invalid or unenforceable term or provision with a term or
provision


                                      -85-
<PAGE>

that is valid and enforceable and that comes closest to expressing the intention
of the invalid or unenforceable term or provision, and this Agreement shall be
enforceable as so modified after the expiration of the time within which the
judgment may be appealed. 11.12 EXPENSES. Except as otherwise specifically
provided to the contrary in this Agreement, each of the Parties shall bear its
own costs and expenses (including legal fees and expenses) incurred in
connection with this Agreement and the transactions contemplated hereby. Buyer
shall bear the filing fees associated with filings under the Hart-Scott-Rodino
Act.

11.13    SPECIFIC PERFORMANCE. Each Party acknowledges and agrees that the other
Party would be damaged irreparably in the event any of the provisions of this
Agreement are not performed in accordance with their specific terms or otherwise
are breached. Accordingly, each Party agrees that the other Party may be
entitled to an injunction or injunctions to prevent breaches of the provisions
of this Agreement and to enforce specifically this Agreement and the terms and
provisions hereof in any action instituted in any court of the United States or
any state thereof having jurisdiction over the Parties and the matter.

11.14    SUBMISSION TO JURISDICTION. Each Party (a) submits to the exclusive
jurisdiction of any state or federal court sitting in the Commonwealth of
Massachusetts in any action or proceeding arising out of or relating to this
Agreement, (b) agrees that all claims in respect of such action or proceeding
may be heard and determined only in any such court, and (c) agrees not to bring
any action or proceeding arising out of or relating to this Agreement in any
other court. Each Party waives any defense of inconvenient forum to the
maintenance of any action or proceeding so brought and waives any bond, surety
or other security that might be required of the other Party with respect
thereto. Either Party may make service on the other Party by sending or


                                      -86-
<PAGE>

delivering a copy of the process to the Party to be served at the address and in
the manner provided for the giving of notices in Section 11.8. Nothing in this
Section 11.14, however, shall affect the right of any Party to serve legal
process in any other manner permitted by law.

11.15    BULK TRANSFER LAWS. Buyer acknowledges that Seller will not comply with
the provisions of the bulk transfer laws of any jurisdiction in connection with
the transaction contemplated by this Agreement.

11.16    CONSTRUCTION. The language used in this Agreement shall be deemed to be
the language chosen by the Parties hereto to express their mutual intent, and no
rule of strict construction shall be applied against any Party. Any reference to
any federal, state, local or foreign statute or law shall be deemed also to
refer to all rules and regulations promulgated thereunder, unless the context
requires otherwise. All references to "$", "Dollars" or "US$" refer to currency
of the United States of America.

identified in this Agreement are incorporated herein by reference and made a
