                                   ARTICLE 2

                                  The Merger

          Section 2.01. The Merger. (a) Subject to the terms and conditions of
this Agreement, at the Effective Time, Merger Subsidiary shall be merged with
and into the Company in accordance with the Delaware Law, whereupon the separate
existence of Merger Subsidiary shall cease, and the Company shall be the
surviving corporation (the "Surviving Corporation").

          (b)  The closing of the transactions contemplated by this Agreement
(the "Closing") shall take place at the offices of Davis Polk & Wardwell, 450
Lexington Avenue, New York, NY 10017, as soon as practicable, but in no event
later than 10 Business Days, after the satisfaction or (subject to applicable
law) waiver of the conditions (excluding conditions that, by their terms, cannot
be satisfied until the Closing Date) set forth in Article 9 (the "Closing
                                                          -
Date"), or at such other time and place as the Company and Parent may agree to
in writing.

          (c)  As soon as practicable following the Closing, the Company and
Merger Subsidiary will file a certificate of merger (the "Certificate of
Merger") with the Delaware Secretary of State and make all other filings or
recordings required by Delaware Law in connection with the Merger in such form
as is required by and executed in accordance with the relevant provisions of
Delaware Law. The Merger shall become effective at such time (the "Effective
Time") as the Certificate of Merger is duly filed with the Delaware Secretary of
State (or at such later time as the parties hereto may agree and as may be
specified in the Certificate of Merger).

          (d)  From and after the Effective Time, the Surviving Corporation
shall possess all the rights, powers, privileges and franchises and be subject
to all of the obligations, liabilities, restrictions and disabilities of the
Company and Merger Subsidiary, all as provided under Delaware Law.

          Section 2.02. Merger Consideration. (a) The Merger Consideration per
share of Common Stock will be the right to receive (i) $11.50 in cash, without
interest (the "Closing Merger Consideration"), and (ii) the Additional Merger
Consideration, if any (the Closing Merger Consideration together, with the
Additional Merger Consideration, if any, the "Merger Consideration").

          (b)  The "Additional Merger Consideration" per share of Common Stock
shall be the right to receive, following a Sagavista Disposition in compliance
with Article 6, payment in cash equal to 80% of any Sagavista Net Proceeds
divided by the number of Adjusted Fully Diluted Shares.

                                       8
<PAGE>

          "Sagavista Net Proceeds" shall mean the gross cash proceeds actually
received by Parent, the Company or any of their respective Subsidiaries on or
prior to October 31, 2002 from any Sagavista Disposition minus (i) all Taxes
payable by the Parent, the Company or any of their respective Subsidiaries as a
result of the Sagavista Disposition, (ii) all out-of-pocket expenses, fees and
costs attributable to the Sagavista Disposition incurred by Parent, the Company
or any of its Subsidiaries or any of their Affiliates after the date hereof,
(iii) any determinable liabilities which may have been retained by Parent, the
Company or any of its Subsidiaries or any of their Affiliates related in any way
to the Sagavista Business, (iv) a reserve, determined by Parent in its sole and
absolute discretion, adequate to satisfy (y) the maximum amount of indemnity
liability of the Company in connection with the Sagavista Disposition and (z)
any liability of the Company, any of its Subsidiaries, the Parent or any
Affiliate of the Parent relating in any manner to the Sagavista Disposition or
any action or inaction by the Parent, the Company or any of its Subsidiaries or
any of their Affiliates in connection with the Sagavista Disposition (provided
however that to the extent any portion of any liabilities for which a reserve
was taken has been cancelled, expired or terminated without payment therefrom
under applicable contract terms or otherwise (as determined in Parent's sole and
absolute discretion) prior to October 31, 2002, then such portion shall be a
part of the Additional Merger Consideration and will be paid as provided in
Section 2.02; provided, further that none of the items listed in this clause
        ----
(iv) shall be deducted more than once), and (v) all out-of-pocket expenses and
costs attributable to the distribution of the Additional Merger Consideration
incurred by the Parent, the Company or any of its Subsidiaries or any of their
Affiliates. Parent shall have sole and absolute discretion in determining the
direct and indirect expenses and liabilities of the Company, any of its
Subsidiaries, the Parent or any Affiliate relating to the Sagavista Disposition
and in determining the amount of any reserve (including estimating Taxes
described in clause (i) above) to be deducted in determining the Sagavista Net
Proceeds. As used in this definition, liabilities includes, without limitation,
all claims, losses, expenses, judgments and liabilities of any type whatsoever,
whether or not known and reasonable expenses of investigation and all fees and
expenses of advisors; provided, however, that the Sagavista Net Proceeds shall
be $0.00 and the right to receive Additional Merger Consideration shall
automatically terminate in the event that the SEC or other Governmental Agency
requires the registration of the Additional Merger Consideration pursuant to the
1933 Act or state securities laws or requires one or more undertakings by any of
Parent, the Company, the Subsidiaries or any of their Affiliates to make
periodic filings with the SEC or such Governmental Agency or other reports to
the stockholders of the Company, whether pursuant the to 1934 Act or state
securities laws or otherwise (such registration or reporting obligations is
referred to as "Registration/ Reporting"), with respect to the Additional Merger
Consideration.

                                       9
<PAGE>

          "Adjusted Fully Diluted Shares" shall equal the sum of the number of
shares of Common Stock outstanding immediately prior to the Effective Time plus
the Eligible Options, in each case, including the shares owned by Parent or its
Affiliates or purchased pursuant to the Stockholder Agreement.

          (c)  In the event the SEC requests Registration/Reporting, Parent and
Company hereby agree to use reasonable efforts for a period of 30 days to
negotiate a mutually acceptable amendment to the terms of the Additional Merger
Consideration to the extent necessary to satisfy the SEC that the Additional
Merger Consideration is not a security as defined in the 1933 Act or the 1934
Act and that Registration/Reporting is not required with respect to the
Additional Merger Consideration provided, however, that Parent shall not be
obligated to take any action or agree to any amendment which would result in any
cost, expense or liability to the Parent, Company or any Affiliate. If changing
the period of time during which stockholders have the right to receive
Additional Merger Consideration to a date earlier than October 31, 2002 would
eliminate the need for Registration/Reporting, Parent and Company agree to
change such date as necessary.

          (d)  In the event that Parent has approved the terms and conditions of
a Sagavista Disposition and the Sagavista Disposition is consummated in
compliance with Article 6 at or prior to the Effective Time, any Additional
                        -
Merger Consideration shall be paid to the stockholders at the same time such
holders receive the Closing Merger Consideration.

          (e)  In the event a Sagavista Disposition is consummated after the
Effective Time but on or prior to October 31, 2002 in compliance with Article 6,
any Additional Merger Consideration will be paid to the stockholders entitled to
receive the Closing Merger Consideration in cash as promptly as practicable
following the consummation of the Sagavista Disposition; provided, however, that
the Surviving Corporation shall not be obligated to pay any amounts until the
earliest of the time (i) that Additional Merger Consideration to be distributed
at that time would equal at least $0.25 per share of Common Stock, (ii) the
Additional Merger Consideration would be the final distribution under this
Section or (iii) within 30 days after October 31, 2002.

          Section 2.03. Conversion of Shares. At the Effective Time:

          (a)  except as otherwise provided in Sections 2.03(b) and 2.05, each
                                                        -------     ----
share of Common Stock outstanding immediately prior to the Effective Time shall
be converted into the right to receive the Merger Consideration payable as
provided in Section 2.02 and 2.04 herein;
                    ----     ----

                                       10
<PAGE>

          (b)  each share of Common Stock held by the Company as treasury stock
(other than shares in an Employee Plan of the Company) or owned by Parent or any
of its Subsidiaries (including the Note Shares purchased pursuant to the
Stockholder Agreement) immediately prior to the Effective Time shall be
canceled, and no payment shall be made with respect thereto; and

          (c)  each share of common stock of 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.

          Section 2.04. Surrender and Payment. (a) Prior to the Effective Time,
Parent shall appoint an agent (the "Exchange Agent") for the purpose of
exchanging certificates representing shares of Common Stock (the "Certificates")
for the Merger Consideration. At or prior to the Effective Time, Parent will
make available, or cause to be made available, to the Exchange Agent, the
aggregate Closing Merger Consideration (and if Section 2.02(d) is applicable,
                                                       -------
the aggregate Additional Merger Consideration, if any) to be paid in respect of
the shares of Common Stock. Promptly after the Effective Time, Parent will send,
or will cause the Exchange Agent to send, to each holder of shares of Common
Stock at the Effective Time a letter of transmittal and instructions (which
shall specify that the delivery shall be effected, and risk of loss and title
shall pass, only upon proper delivery of the Certificates to the Exchange Agent)
for use in such exchange.

          (b)  Each holder of shares of Common Stock that have been converted
into the right to receive the Merger Consideration will be entitled to receive
promptly following the Effective Time, upon surrender to the Exchange Agent of a
Certificate, together with a properly completed letter of transmittal, the
Closing Merger Consideration (and if Section 2.02(d) is applicable, the
                                             -------
Additional Merger Consideration, if any) in respect of the Common Stock
represented by such Certificate. Until so surrendered, each such Certificate
shall represent after the Effective Time for all purposes only the right to
receive the Merger Consideration.

          (c)  If any portion of the Merger Consideration is to be paid to a
Person other than the Person in whose name the Certificate is registered, it
shall be a condition to such payment that the Certificate so surrendered shall
be properly endorsed or otherwise be in proper form for transfer and that the
Person requesting such payment shall pay to the Exchange Agent any transfer or
other taxes required as a result of such payment to a Person other than the
registered holder of such Certificate or establish to the satisfaction of the
Exchange Agent that such tax has been paid or is not payable. Additional Merger
Consideration shall only be paid to those Persons who receive the Closing Merger
Consideration.

                                       11
<PAGE>

          (d)  After the Effective Time, there shall be no further registration
of transfers of shares of Common Stock. If, after the Effective Time,
Certificates are presented to the Surviving Corporation, they shall be canceled
and exchanged for the Merger Consideration provided for, and in accordance with
the procedures set forth, in this Article.

          (e)  Any portion of the Merger Consideration made available to the
Exchange Agent pursuant to Section 2.04(a) that remains unclaimed by the holders
                                   -------
of shares of Common Stock six months after the Effective Time shall be returned
to the Surviving Corporation, upon demand, and any such holder who has not
exchanged such shares for the Merger Consideration in accordance with this
Article prior to that time shall thereafter look only to the Surviving
Corporation for payment of the Merger Consideration, in respect of such shares
without any interest thereon. Notwithstanding the foregoing, neither Parent nor
the Surviving Corporation shall be liable to any holder of shares of Common
Stock for any amounts paid to a public official pursuant to applicable abandoned
property, escheat or similar laws. Any amounts remaining unclaimed by holders of
shares of Common Stock three years after the Effective Time (or such earlier
date, immediately prior to such time when the amounts would otherwise escheat to
or become property of any governmental authority) shall become, to the extent
permitted by applicable law, the property of the Surviving Corporation free and
clear of any claims or interest of any Person previously entitled thereto, other
than any such claim or interest which any Person would otherwise have thereto
under applicable law if such amounts had escheated to, or otherwise become the
property of, any governmental authority, provided such Person establishes such
claim or interest as if such claim or interest were to be established pursuant
to applicable law if such amounts had escheated to, or otherwise become the
property of, any governmental authority.

          (f)  Any portion of the Merger Consideration made available to the
Exchange Agent pursuant to Section 2.04(a) to pay for shares of Common Stock for
                                   -------
which appraisal rights have been perfected pursuant to Section 2.05 hereto shall
                                                               ----
be returned to Surviving Corporation, upon demand.

          (g)  Parent shall enter into an exchange agent agreement with the
Exchange Agent which shall set forth the duties, responsibilities and
obligations of the Exchange Agent consistent with the terms of this Agreement
and otherwise reasonably satisfactory to Parent and the Company.

          Section 2.05. Dissenting Shares. Notwithstanding anything in this
Agreement to the contrary, shares of Common Stock which are issued and
outstanding immediately prior to the Effective Time and which are held by a
holder who has not voted such shares in favor of the Merger, who shall have

                                       12
<PAGE>

delivered a written demand for appraisal of such shares in the manner provided
by the Delaware Law and who, as of the Effective Time, shall not have
effectively withdrawn such demand or lost such right to appraisal and payment
therefor under the Delaware Law ("Dissenting Shares") shall not be converted
into a right to receive the Merger Consideration. The holders thereof shall be
entitled only to such rights as are granted by Section 262 of the Delaware Law.
Each holder of Dissenting Shares who becomes entitled to payment for such shares
pursuant to Section 262 of the Delaware Law shall receive payment therefor from
the Surviving Corporation in accordance with the Delaware Law; provided,
however, that (i) if any such holder of Dissenting Shares shall have failed to
establish his or her entitlement to appraisal rights as provided in Section 262
of the Delaware Law, (ii) if any such holder of Dissenting Shares shall have
effectively withdrawn his or her demand for appraisal of such shares or lost his
or her right to appraisal and payment for his or her shares under Section 262 of

Surviving Corporation shall have filed a petition demanding a determination of
the value of all Dissenting Shares within the time provided in Section 262 of
the Delaware Law, such holder shall forfeit the right to appraisal of such
shares and each such share shall be treated as if it had been, as of the
Effective Time, converted into a right to receive the Merger Consideration,

----
any demands received by the Company for appraisal of shares, and Parent shall

Parent, make any payment with respect to, or settle or offer to settle, any such

determined by multiplying (i) the excess, if any, of the Merger Consideration
over the applicable exercise price of such option by (ii) the number of shares

plus the Additional Merger Consideration, if any.

for less than the Merger Consideration could have purchased is referred to in

applicable exercise price of such option plus all Additional Merger
Consideration previously paid to such holder by (ii) such holder's Eligible
Options in the same manner and as, when and if paid by the Company pursuant to
Section 2.02(e).

--------

          (d)  The Company agrees that it will not initiate any new Option

this Agreement and the Effective Time, any change in the outstanding shares of
Common Stock shall occur, including by reason of any reclassification,
recapitalization, stock split or combination, exchange or readjustment of
shares, or any stock dividend thereon with a record date during such period, the
Merger Consideration and any other amounts payable pursuant to this Agreement
shall be appropriately adjusted.

          Section 2.08. Withholding Rights. Each of the Surviving Corporation
and Parent shall be entitled to deduct and withhold from the consideration
otherwise payable to any Person pursuant to this Article such amounts as it is
required to deduct and withhold with respect to the making of such payment under
any provision of federal, state, local or foreign tax law. If the Surviving
Corporation or Parent, as the case may be, so withholds amounts, such amounts
shall be timely remitted to the applicable Taxing Authority and shall be treated
for all purposes of this Agreement as having been paid to the holder of the
shares of Common Stock in respect of which the Surviving Corporation or Parent,
as the case may be, made such deduction and withholding.

such reasonable amount as the Surviving Corporation may direct, as indemnity
against any claim that may be made against it with respect to such Certificate,
the Exchange Agent will issue, in exchange for such lost, stolen or destroyed
Certificate, the Merger Consideration to be paid in respect of the shares of
Common Stock represented by such Certificate, as contemplated by this Article.

                                              ----

supplement thereto is first mailed to stockholders of the Company and at the
time the stockholders vote on adoption of this Agreement and at the Effective
Time, will contain any untrue statement of a material fact or omit to state any

paid by Parent, there is no investment banker, broker, finder or other
intermediary that has been retained by or is authorized to act on behalf of

                           Covenants of the Company

          The Company agrees that:

          Section 6.01. Conduct of the Company. (a) Except as otherwise
specifically provided in this Agreement or as approved in writing by Parent,
from the date hereof to the Effective Time, the Board of Directors of the
Company shall not approve or authorize any action that would allow the Company
and its Subsidiaries to carry on their respective businesses other than in the
ordinary and usual course of business and consistent with past practice or any
action that would prevent the Company and the Subsidiaries, as a whole, from (1)
preserving intact its present business organization and (2) maintaining
satisfactory relationships with its material customers, lenders, suppliers and
others having business relationships with it. Neither the Company nor its
Subsidiaries shall be deemed to be in breach of this Section if a provision of
this Section specifically permits an action to be taken by the Company or its
Subsidiaries even in the case such action may be prohibited by other provisions
of this Section which may be broader or more general in scope. Without limiting
the generality of the foregoing, and except as otherwise specifically provided
in this Agreement, without the prior

                                       34

         and warranties of the Company hereunder inaccurate in any material
         respect at, or as of any time prior to, the Effective Time, or omit to
         take any action within the reasonable control of the Company necessary
         to prevent any such representation or warranty from being inaccurate in
         any material respect at any such time;

               (iv)  enter into any agreement or commitment relating to the sale
         of products if any such agreement or commitment involves the
         expenditure by the Company of amounts in excess of $500,000; provided

         the other party to the agreement or commitment a discount to list
         prices which is higher than the discounts from list prices the Company
         has generally granted prior to the date hereof to similarly situated
         customers for an agreement of a similar type taking into account the
         length and the nature of the relationship the Company has with the
         counterparty, the dollar amount of the contract, the size of the

         employee, or (except for normal increases in the ordinary course of
         business that are consistent with past practices and that, in the
         aggregate, do not result in a material increase in benefits or

         otherwise required by law) increase in any manner the compensation or
         fringe benefits of any director, officer or employee or pay any benefit
         not required by any existing plan or arrangement (including, without
         limitation, the granting of stock options or stock appreciation rights
         or the removal of existing restrictions in any benefit plans or
         agreements, except for normal increases in non-executive employee
         compensation in the ordinary course of business that are consistent
         with past practices and that, in the aggregate, do not result in a
         material increase in benefits or compensation expense to the Company or

December 31, 2000 shall be considered a "Business Day") prior to entering into

         Section 6.02. Stockholder Meeting; Proxy Material. (a) The Company
shall cause a meeting of its stockholders (the "Company Stockholder Meeting") to
be duly called and held as soon as reasonably practicable for the purpose of
voting on the approval and adoption of this Agreement and the Merger. Subject to
Section 6.03(b), the Board of Directors of the Company shall recommend approval
and adoption of this Agreement and the Merger by the Company's stockholders. In

prepare and file with the SEC, use its reasonable best efforts to have cleared
by the SEC and thereafter mail to its stockholders as promptly as practicable

subject to 6.03(b), use its reasonable efforts to obtain the necessary approvals
by its stockholders of this Agreement and the transactions contemplated hereby
and (iii) otherwise comply with all legal requirements applicable to such
meeting.

         (b)   The Company shall deliver, and give Parent an opportunity to
comment on, prior to filing with the SEC and mailing to the Company's
stockholders, the Company Proxy Statement. Parent will be reasonably satisfied
with the content of the Company Proxy Statement dealing with it or its
Affiliates prior to the Company filing a definitive Company Proxy Statement.

         Section 6.03. No Solicitation. (a) Except to the extent permitted by
Section 6.04 neither the Company nor any of its Subsidiaries shall, nor shall
the Company or any of its Subsidiaries authorize or permit any of its or their
officers, directors, employees, investment bankers, attorneys, accountants,
consultants or other agents or advisors (its "Representatives") to, directly or
indirectly, (i) solicit, initiate or knowingly take any action to facilitate or
encourage the submission of any Acquisition Proposal, (ii) enter into or
participate in any discussions or negotiations with, furnish any information
relating to the Company or any of its Subsidiaries or afford access to the
business, properties, assets, books or records of the Company or any of its
Subsidiaries to, otherwise cooperate in any way with, or knowingly assist,
participate in, facilitate or encourage any effort by any Third Party that is
seeking to make, or has made, an Acquisition Proposal or (iii) grant any waiver
or release under any standstill or similar agreement with respect to any class
of equity securities of the Company or any of its Subsidiaries.

         (b)   Notwithstanding the Section 6.02 and 6.03(a), the Board of
Directors of the Company, directly or indirectly through advisors, agents or
other intermediaries, may (i) engage in negotiations or discussions with any
Third Party that has made a Superior Proposal which did not result, in whole or
in part, from a breach of Section 6.03(a), (ii) furnish to such Third Party
nonpublic information relating to the Company or any of its Subsidiaries
pursuant to a confidentiality agreement with terms no less favorable to the
Company than those contained in the Confidentiality Agreement dated as of July
26, 2000 between the Company

                                       38
<PAGE>

and Parent (the "Confidentiality Agreement"), (iii) take and disclose to its
stockholders a position in compliance by Rule 14e-2(a) under the 1934 Act or
otherwise make disclosure to them, (iv) following receipt of such Superior
Proposal, fail to make, withdraw, or modify in a manner adverse to Parent its
recommendation to its stockholders referred to in Section 6.02 hereof or fail to
call the Company Stockholder Meeting in accordance with Section 6.02 hereof
and/or (v) take any non-appealable, final action ordered to be taken by the
Company by any court of competent jurisdiction, but in each case referred to in
the foregoing clauses (i) through (iv) only if the Board of Directors of the
Company determines in good faith by a majority vote, after consultation with and
based on the advice from King & Spalding, outside legal counsel to the Company,
that it must take such action to comply with its fiduciary duties under
applicable law.

         (c)   The Board of Directors of the Company shall not take any of the
actions referred to in clauses (i) through (iv) of the preceding subsection
unless the Company shall have delivered to Parent a prior (and if not
practicable, contemporaneously) written notice advising Parent that it intends
to take such action, and the Company shall continue to advise Parent after
taking such action. In addition, the Company shall notify Parent promptly (but
in no event later than 24 hours) after receipt by the Company (or any of its
advisors) of any Acquisition Proposal, any indication that a Third Party is
considering making an Acquisition Proposal or of any request for information
relating to the Company or any of its Subsidiaries or for access to the
business, properties, assets, books or records of the Company or any of its
Subsidiaries by any Third Party that may be considering making, or has made, an
Acquisition Proposal. The Company shall provide such notice orally and in
writing and shall identify the Third Party making, and the terms and conditions
of, any such Acquisition Proposal, indication or request. The Company shall keep
Parent informed, on as current basis as practicable, of the status and details
of any such Acquisition Proposal, indication or request. The Company shall, and
shall cause its Subsidiaries and the advisors, employees and other agents of the
Company and any of its Subsidiaries to, cease immediately and cause to be
terminated any and all existing activities, discussions or negotiations, if any,
with any Third Party conducted prior to the date hereof with respect to any
Acquisition Proposal and shall use its reasonable best efforts to cause any such
Party (or its agents or advisors) in possession of confidential information
about the Company that was furnished by or on behalf of the Company to return or
destroy all such information.

         "Superior Proposal" means any bona fide, unsolicited written
Acquisition Proposal (provided that all references to 20% shall be deemed to be
50%) on terms that the Board of Directors of the Company determines in good
faith by a majority vote, on the basis of the advice of a financial advisor of
nationally recognized reputation and taking into account all the terms and

                                       39
<PAGE>

conditions of the Acquisition Proposal, including any break-up fees, expense
reimbursement provisions and conditions to consummation, are more favorable and
provide greater value (considering all factors deemed relevant by the Board of
Directors) to all the Company's stockholders than as provided hereunder and for
which financing, to the extent required, is then fully committed or reasonably
determined to be available by the Board of Directors of the Company.

         Section 6.04. Disposition of Sagavista Business. Until the Effective
Time, the Company may not, and may not permit its Representatives to, solicit
proposals for or engage in any discussions regarding the acquisition of all or a
part of the Sagavista Business (the "Sagavista Disposition") other than on a
basis which is limited to the assets used exclusively in the Sagavista Business
and requires the assumption of all liabilities relating to the Sagavista
Business and which does not result in or impose any adverse impact, financial or
otherwise, or liability on the Company, its Subsidiaries, Parent or their
Affiliates, in any case without Parent's consent in writing, which consent may
be withheld or withdrawn at any time in Parent's sole and absolute discretion.
In any case, prior to (x) soliciting any proposal from any Person for or
relating to the Sagavista Disposition, or (y) providing any information to any
Person relating to the Sagavista Business or Sagavista Disposition, the Company
shall notify Parent in writing of such proposal or information and shall not act
without the prior express written consent of Parent. The Company and its
advisors shall keep Parent fully informed on a current basis on the status,
details and progress of any negotiations and such further information as Parent
may request concerning a Sagavista Disposition. A Sagavista Disposition shall
include after the Effective Time, any transaction which transfers all or
substantially all of the rights exclusively related to the Sagavista Business in
a manner which is economically equivalent to a Sagavista Disposition (such as
the licencing of the Sagavista product to a third party to be managed by and for
the benefit of such third party, but not in the ordinary course of running the
Sagavista Business, such as entering into contracts concerning the Sagavista
product similar to those contracts the Company enters into concerning the
Parent's products). After the Effective Time and on or prior to October 31,
2002, Parent shall not, and shall not permit the Company or any of their
respective Subsidiaries to, effect any Sagavista Disposition other than in a
transaction in which the consideration due from any third party is payable
solely in cash ("Cash Consideration") prior to October 31, 2002; provided,
however, that Cash Consideration may be payable after October 31, 2002 if the
Parent agrees to extend the date in the definition of Sagavista Net Proceeds
from October 31, 2002 to such date as such Cash Consideration is received by
Parent, Company or any of their respective Subsidiaries.

         As used in this Section, the term "liability" and "liabilities" include
all claims, losses, expenses, judgements and liabilities of any type whatsoever,
and whether fixed, matured or contingent, and whether or not known (including,

                                       40
<PAGE>

without limitation, reasonable expenses of investigation and reasonable fees and
expenses of advisors).

         Section 6.05. Access to Information. From the date hereof until the
Effective Time or the termination of this Agreement and subject to applicable
law and the Confidentiality Agreement, the Company shall (i) upon reasonable
notice give Parent, its counsel, financial advisors, auditors and other
authorized representatives reasonable access during business hours to the
offices, properties, books and records of the Company and the Subsidiaries, (ii)
upon reasonable notice furnish to Parent, its counsel, financial advisors,
auditors and other authorized representatives such financial and operating data
and other information as such Persons may reasonably request and (iii) instruct
the employees, counsel, financial advisors, auditors and other authorized
representatives of the Company and its Subsidiaries to cooperate with Parent in
its investigation of the Company and its Subsidiaries. Any investigation
pursuant to this Section shall be conducted in such manner as not to interfere
unreasonably with the conduct of the business of the Company and its
Subsidiaries. No information or knowledge obtained by Parent in any
investigation pursuant to this Section shall affect or be deemed to modify any
representation or warranty made by the Company hereunder.

         Section 6.06. Tax Matters. (a) From the date hereof until the Effective
Time, the Company and its Subsidiaries shall not without prior written consent
of Parent (which consent shall not be unreasonably withheld) make or change any
Tax election, change any annual Tax accounting period, adopt or change any
method of Tax accounting, file any amended Returns or claims for Tax refunds,
enter into any closing agreement, surrender any Tax claim, audit or assessment,
surrender any right to claim a Tax refund, offset or other reduction in Tax
liability surrendered, consent to any extension or waiver of the limitations
period applicable to any Tax claim or assessment or take or omit to take any
other action, if any of the foregoing actions or omissions (i) is not in the
ordinary course of business consistent with past practice and (ii) would have
the effect of increasing the Tax liability or reducing any Tax Asset of the
Company or any of its Subsidiaries.

         (b)   From the date hereof until the Effective Time, the Company and
each of its Subsidiaries will establish or cause to be established in accordance
with U.S. GAAP an adequate accrual for all Taxes due with respect to any
Pre-Effective Tax Period.

         (c)   On or prior to the Effective Time, the Company shall deliver to
Parent a certification signed by an officer of the Company to the effect that
the Company is not nor has it been within 5 years of such date a "United States
real property holding corporation as defined in Section 897 of the Code".

                                       41

         Section 6.07. Retention Bonuses. In the event that the sum of the line
items "Cash and cash equivalents" and "Short-term investments" on the Company's
balance sheet calculated in accordance with U.S. GAAP applied in a manner
consistent with prior practice has increased from $56.3 million on September 30,
2000 to at least $60 million on the Company's balance sheet as of December 31,
2000 prepared in accordance with U.S. GAAP applied on a basis consistent with
past practice as certified to the Parent by the Chief Financial Officer of the
Company (which is supported by a bank certification regarding bank balances of
the Company) as a result of operating cash flow and not as a result of financing
activities or of a Sagavista Disposition (the "Cash Balance") the Company shall
be permitted to pay at the Effective Time an aggregate amount, which amount
shall not exceed $3 million, equal to the excess of the Cash Balance over $ 60
million, to employees selected by and in individual amounts determined in the
Company's sole and absolute discretion.

                                   ARTICLE 7

                              Covenants of Parent

         Parent agrees that:

         Section 7.01. Confidentiality. Prior to the Effective Time and after
any termination of this Agreement, Parent will hold, and will use its best
efforts to cause its officers, directors, employees, accountants, counsel,
consultants, advisors and agents to hold, in confidence, unless compelled to
disclose by judicial or administrative process or by other requirements of law,
all confidential documents and information concerning the Company or any of its
Subsidiaries furnished to Parent or its Affiliates in connection with the
transactions contemplated by this Agreement, except to the extent that such
information can be shown to have been (i) previously known on a non-confidential
basis by Parent, (ii) in the public domain through no fault of Parent or (iii)
later lawfully acquired by Parent from sources other than the Company, provided
that Parent may disclose such information to its officers, directors, employees,
accountants, counsel, consultants, advisors and agents in connection with the
transactions contemplated by this Agreement so long as Parent informs such
Persons of the confidential nature of such information and directs them to treat
it confidentially. Parent and its Affiliates shall satisfy their obligation to
hold any such information in confidence if they exercise the same care with
respect to such information as they would take to preserve the confidentiality
of their own similar information. If this Agreement is terminated, Parent and
its Affiliates will, and will use their best efforts to cause their officers,

Agreement, each Stockholder has agreed to enter into this Agreement with respect
to all Owned Shares;

         NOW, THEREFORE, in consideration of the foregoing and the

stockholder's "Note Shares") in exchange for a Subordinated Note of Parent in
the Form of Exhibit 1 hereto (a "Subordinated Note") in an aggregate principal
amount equal to (x) the number of such Thayer Stockholder's Note Shares
multiplied by (y) the Merger Consideration. Each Thayer Stockholder agrees that

such Thayer Stockholder in cash an amount per Note Share equal to the amount of
Additional Merger Consideration per share of Common Stock so paid by the
Company.

expired or been terminated, (ii) any other required governmental approval shall
have been obtained and (iii) no law, regulation, judgment, order or decree shall

         Section 5.06. Counterparts. This Agreement may be executed in one or

         Section 5.07. Governing Law. The validity, construction and effect of
this Agreement shall be governed by and construed enforced in accordance with
the laws of the State of Delaware, without giving effect to the principles of
conflicts of law of such state.

         Section 5.08. Enforcement. The parties agree that irreparable damage
would occur in the event that any of the provisions of this Agreement were not
performed by the parties in accordance with their specific terms or were
otherwise breached. It is accordingly agreed that, in addition to any other
remedy to which it may be entitled, at law or in equity, the parties shall be
entitled to the remedy of specific performance of the covenants and agreements
contained herein and injunctive and other equitable relief and the parties
hereto further agree to waive any requirement for the securing or posting of any
bond in connection with the obtaining of any such injunctive or other equitable
relief. The parties agree that time shall be of essence in the performance of
obligations hereunder.

         Section 5.09. Parties in Interest. This Agreement shall be binding upon

nature whatsoever under or by reason of this Agreement.

         Section 5.10. Severability. Whenever possible, each provision or

to be effective and valid under applicable law, but if any provision or portion
of any provision of this Agreement is held to be invalid, illegal or
unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or portion of any provision in such jurisdiction, and this
Agreement will be reformed, construed and enforced in such jurisdiction as if
such invalid, illegal or unenforceable provision or portion of any provision had
never been contained herein.

         Section 5.11. Definitions; Headings; Construction. Capitalized terms
used but not defined herein have the meanings assigned to them in the Merger
Agreement. When a reference is made in this Agreement to Sections, such
reference shall be to a Section of this Agreement unless otherwise indicated.
The headings contained in this Agreement are for convenience of reference only
and shall not affect the meaning or interpretation of this Agreement. Wherever
the

                                      12
<PAGE>

words "include", "includes" or "including" are used in this Agreement, they
shall be deemed to be followed by the words "without limitation". For purposes
of this Agreement:

          (a) "Beneficially own" or "beneficial ownership" with respect to any
securities shall mean having "beneficial ownership" of such securities (as
determined pursuant to Rule 13d-3 under the Exchange Act), including pursuant to
any agreement (other than by virtue of this Agreement), arrangement or
understanding, whether or not in writing. Without duplicative counting of the
same securities by the same holder, securities beneficially owned by a Person
shall include securities Beneficially Owned by all other Persons with whom such
Person would constitute a "group" as described in Section 3(d)(3) of the 1934
Act.

          (b) "Person" shall mean an individual, corporation, partnership,
limited liability company, joint venture, association, trust, unincorporated
organization or other entity.

          (c) In the event that any Persons are added to Schedule A, such
Persons shall be included in the definition of the term "Stockholder".

          (d) In the event of a stock or other dividend or distribution, or any
change in the Common Stock by reason of any stock dividend, split-up,
recapitalization, combination, exchange of shares or the like, the term "Shares"
shall be deemed to refer to and include the Shares as well as all such dividends
and distributions and any shares into which or for which any or all of the
Shares may be changed or exchanged.

          Section 5.12. Stockholder Capacity. Notwithstanding anything herein to
the contrary, no Person executing this Agreement who or whose representative or
officer is, or becomes during the term hereof, a director of the Company makes
any agreement or understanding herein in his capacity as a, or with respect to
any, director, and the agreements set forth herein shall in no way restrict any
director in the exercise of such director's fiduciary duties as a director of
the Company.
