shall be accounted for as a pooling of interests;

            NOW, THEREFORE, in consideration of the foregoing, and the
representations, warranties and covenants herein contained, and for other
good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the Parties, intending to be legally bound, agree as

Stock") in accordance with this Article II (the "Series A Exchange Ratio")
shall be determined by dividing (x) an amount equal to $9.99 plus any
declared but unpaid dividends on such share of Series A Preferred Stock
(such amount, the "Series A Amount") by (y) $84.5705 (the amount referenced

Stock Price"). The aggregate number of shares of Series A Preferred Stock
to be converted in the Merger pursuant to this Article II multiplied by the
Series A Amount is hereinafter referred to as the "Series A Proceeds."

                  (b) The number of shares (or fraction of a share) of
Buyer Common Stock to be issued in the Merger for each share of Series B
Preferred Stock, par value $0.01 per share, of the Company ("Series B
Preferred Stock") in accordance with this Article II (the "Series B
Exchange Ratio") shall be determined by dividing an amount equal to $14.99
plus any declared but unpaid dividends on such share of Series B Preferred
Stock (such amount, the "Series B Amount") by the Average Buyer Common
Stock Price. The aggregate number of shares of Series B Preferred
Stock to be converted in the Merger pursuant to this Article II multiplied
by the Series B Amount is hereinafter referred to as the "Series B
Proceeds."

                  (c) The number of shares (or fraction of a share) of
Buyer Common Stock to be issued in the Merger for each share of Series C
Preferred Stock, par value $0.01 per share, of the Company ("Series C

Exchange Ratio") shall be determined by dividing an amount equal to $2.19
plus any declared but unpaid dividends on such share of Series C Preferred

Series C Amount is hereinafter referred to as the "Series C Proceeds."

                  (d) The number of Shares (or fraction of a share) of
Buyer Common Stock to the issued in the Merger for each shares of Series D
Preferred Stock, par value $0.01 per share, of the Company ("Series D

Exchange Ratio") shall be determined by dividing an amount equal to $3.69
plus any declared but unpaid dividends on such share of Series D Preferred
Stock (such amount, the "Series D Amount") by the Average Buyer Common
Stock Price. The aggregate number of shares of Series D Preferred Stock to

be determined by dividing (i) an amount equal to $2.4 billion less the
Aggregate Preferred Stock Proceeds by (ii) the Fully Diluted Common Stock
Number (as defined herein) and dividing the result obtained thereby by the
Average Buyer Common Stock Price. For purposes of this Agreement, shares of
Series D Preferred Stock that are converted into Common Stock in accordance
with the Certificate of Incorporation (as defined in Section 3.1(b) hereof)
prior to the Effective Time (the "Series D Preferred Stock Conversion")
shall not be considered to be shares of Series D Preferred Stock issued and
outstanding as of immediately prior to the Effective Time, but shall be
considered to have been so converted.

                  (f) The aggregate number of shares of Buyer Common Stock
to be issued in the Merger in accordance with this Article II is
hereinafter referred to as the "Merger Shares", 90% of such aggregate

of Merger Shares to be received by all Company Stockholders in the Merger
pursuant to this Article II, is hereinafter referred to as such Company
Stockholder's "Ownership Percentage Interest."

                  (g) At the Closing, the Company shall deliver to the
Buyer a certificate, in form and substance satisfactory to the Buyer and

2.1(g) of the Disclosure Schedule (the "Outstanding Offers"), other than

the number of shares of Common Stock underlying all warrants to purchase
Common Stock or Series D Preferred Stock ("Warrants"), whether or not
exercisable, outstanding as of immediately prior to the Effective Time;
(iv) as to the number of shares of Common Stock outstanding as of

assuming that all Options referred to in (ii) above (excluding any Options
granted after the date hereof in accordance with Section 5.1(a) to newly
hired employees whose offer of employment was made after the date hereof
but including the number of shares of Common Stock underlying Outstanding
Offers, other than shares underlying Outstanding Offers that the Parties
reasonably agree have been terminated as of immediately prior to the
Effective Time and all Warrants referred to in (iii) above, in each such
case whether or not vested or exercisable, have been exercised in full
(such number of shares of Common Stock being referred to as the "Fully
Diluted Common Stock Number"); and (v) by reference to a schedule to
the Company Closing Certificate, as to a list of all the holders of shares
of Common Stock and Preferred Stock outstanding as of immediately prior to
the Effective Time, after giving effect to the Series D Preferred Stock
Conversion, as such names appear on the stock transfer books of the Company
(individually, a "Company Stockholder" and collectively, the "Company
Stockholders") and the number of shares of Common Stock and Preferred Stock
held by each Company Stockholder. The Schedule containing the information
referred to in clause (v) of the immediately preceding sentence, upon
acceptance by the Buyer at the Closing (such acceptance not to be
unreasonably withheld), shall be appended as Schedule 1 to this Agreement
and shall be deemed incorporated herein and made a part hereof and shall
hereinafter be referred to as the "Closing Stockholder Schedule."

            2.2   Conversion of Capital Stock.  At the Effective Time, by
virtue of the Merger and without any action on the part of the holder of
any shares of Common Stock or of capital stock of Sub:

                  (a) Capital Stock of Sub. Each issued and outstanding
share of common stock, par value $.01 per share, of Sub shall be converted
into and become one fully paid and nonassessable share of common stock, par
value $.01 per share, of the Surviving Corporation.

                  (b) Cancellation of Treasury Stock. All shares of Common
Stock or Preferred Stock that are owned by the Company as treasury stock,
if any, shall be cancelled and retired and shall cease to exist and no
stock of the Buyer or other consideration shall be delivered in exchange
therefor.

                  (c) Company Stock. Subject to Sections 2.3, 2.5 and 2.7,
each share of Common Stock issued and outstanding as of immediately prior
to the Effective Time (other than shares of Common Stock cancelled in

Section 2.7)) shall be converted into the right to receive a number of
validly issued, fully paid and nonassessable shares (or cash in lieu of a
fraction of a share) of Buyer Common Stock equal to the Common Stock
Exchange Ratio. All such shares of Common Stock, when so converted, shall
no longer be outstanding and shall automatically be cancelled and retired
and shall cease to exist, and each holder of a certificate formerly
representing any such shares shall cease to have any rights with respect
thereto, except the right to receive the shares of Buyer Common Stock
pursuant to this Section 2.2(c), and any cash in lieu of fractional shares
payable pursuant to Section 2.5, upon the surrender of such certificate and
the other documents referred to in Section 2.3(a), in accordance with such
Section (collectively, the "Common Stock Merger Consideration"). Subject to
Sections 2.3 and 2.5, (i) each share of Series A Preferred Stock issued and
outstanding as of immediately prior to the Effective Time (other than
shares of Series A Preferred Stock cancelled in accordance with Section
2.2(b)) shall represent only the right to receive a number of validly
issued, fully paid and nonassessable shares (or cash in lieu of a fraction
of a share) of Buyer Common Stock equal to the Series A Exchange Ratio;
(ii) each share of Series B Preferred Stock issued and outstanding as of
immediately prior to the Effective Time (other than shares of Series B
Preferred Stock cancelled in accordance with Section 2.2(b)), shall
represent only the right to receive a number of validly issued, fully paid
and nonassessable shares (or cash in lieu of a fraction of a share) of
Buyer Common Stock equal to the Series B Exchange Ratio; (iii) each share
of Series C Preferred Stock issued and outstanding as of immediately prior
to the Effective Time (other than shares of Series C Preferred Stock
cancelled in accordance with Section 2.2(b)) shall represent only the right
to receive a number of validly issued, fully paid and nonassessable shares
(or cash in lieu of a fraction of a share) of Buyer Common Stock equal to
the Series C Exchange Ratio; and (iv) each share of Series D Preferred
Stock issued and outstanding as of immediately prior to the Effective Time
(other than shares of Series D Preferred Stock cancelled in accordance with
Section 2.2(b)) shall represent only the right to receive a number of
validly issued, fully paid and nonassessable shares (or cash in lieu of a
fraction of a share) of Buyer Common Stock equal to the Series D Exchange
Ratio. All such shares of Preferred Stock, when so converted, shall no
longer be outstanding and shall automatically be cancelled and retired and
shall cease to exist, and each holder of a certificate formerly
representing any such shares shall cease to have any rights with respect
thereto, except the right to receive the shares of Buyer Common Stock
pursuant to this Section 2.2(c), and any cash in lieu of fractional shares
payable pursuant to Section 2.5, upon the surrender of such certificate and
the other documents referred to in Section 2.3(a), in accordance with such
Section (the "Preferred Stock Merger Consideration" and, together with the
Common Stock Merger Consideration, the "Merger Consideration").

                  (d) Adjustment of Exchange Ratios. In the event the Buyer
changes the number of shares of Buyer Common Stock issued and outstanding
prior to the Effective Time pursuant to a stock split, stock dividend,
recapitalization, subdivision, reclassification, combination, exchange of
shares or similar transaction with respect to the outstanding Buyer Common
Stock and the record date therefor shall be prior to the Effective Time,
(i) the Common Stock Exchange Ratio (for purposes of this Article II and
Section 6.7) and (ii) each of the Series A Exchange Ratio, the Series B
Exchange Ratio, the Series C Exchange Ratio and the Series D Exchange Ratio

and who shall have demanded properly in writing appraisal for such shares
in accordance with Section 262 of the DGCL and who shall not have withdrawn
such demand or otherwise have forfeited appraisal rights (collectively, the

entitled to receive payment of the appraised value of such shares of Common
Stock held by them in accordance with the provisions of such Section 262,
except that all Dissenting Shares held by Company Stockholders who shall
have failed to perfect or who effectively shall have withdrawn or lost

provided in Section 2.3(a), of the certificate or certificates which
immediately prior to the Effective Time represented such shares of Common
Stock and the delivery of the other documents required to be delivered

auditors, and (b) an unaudited balance sheet as at April 30, 2000 (the

referred to in such financial statements, all in accordance with United
States generally accepted accounting principles ("GAAP") applied on a basis
consistent with prior periods, subject in the case of interim statements to
normal recurring year-end adjustments that are not likely to be material in
amount and the absence of notes.

            3.6  Books and Records. The books of account of the Company are
complete and correct in all material respects and have been maintained in
accordance with sound business practices. The Company has made and kept
books, records and accounts which, in reasonable detail, accurately and
fairly reflect its transactions and the dispositions of its assets. The
Company maintains a system of accounting controls sufficient to provide
reasonable assurances that (a) transactions are executed in accordance with
management's general or specific authorization; (b) transactions are
recorded as necessary (i) to permit preparation of financial statements in
conformity with GAAP and (ii) to maintain accountability for assets; (c)
access to assets is permitted only in accordance with management's general
or specific authorization; and (d) the recorded accounting for assets is
compared with the existing assets at reasonable intervals and appropriate
action is taken with respect to any differences.

extent of the amounts specifically reflected or reserved on the balance
sheet as at December 31, 1999 (the "Audited Balance Sheet"), (b)
obligations under Contracts entered into in the ordinary course of business
and consistent with past practice and not in excess of current requirements

Sheet, (c) liabilities and obligations incurred in the ordinary course of
business consistent with past practice since the date of the Audited
Balance Sheet and (d) as set forth in Section 3.7 of the Disclosure
Schedule, the Company does not have any liabilities or obligations of any
nature whether absolute, accrued, known, or unknown, contingent or
otherwise and whether due or to become due, which individually or in the
aggregate would have a Material Adverse Effect.

            3.8 Accounts Receivable. All accounts receivable of the
Company, whether reflected in the Interim Balance Sheet or otherwise,
represent sales actually made in the ordinary course of business and have
been reflected properly in its books and records.

            3.9 Inventory. All of the inventories of the Company consist
of a quality and quantity usable and salable in the ordinary and usual
course of business, except for items of obsolete materials and materials of
below-standard quality, all of which items have been written off or written
down on the Financial Statements to fair market value or for which adequate
reserves have been provided therein. All inventories not written off have
been priced at the lower of average cost or market. The quantities of each
type of inventory (whether raw materials, work-in-process, or finished
goods) are not excessive, but are reasonable and warranted in the present
circumstances of the Company. All finished goods inventory held by the
Company is free of any defect or other deficiency.

            3.10 Assets. Except as set forth in Section 3.10 of the
Disclosure Schedule, the Company has good and marketable title, free and
clear of all Liens, to (i) all of its assets and properties reflected as
owned on the Audited Balance Sheet, except for assets and properties
disposed of, or subject to purchase or sales orders, in the ordinary course
of business since the date of the Audited Balance Sheet and (ii) all of the
Company's other assets, real property, interests in real property, rights,
franchises, copyrights, trademarks, trade names, licenses and properties,
tangible or intangible, real or personal, wherever located which are used
in the conduct of its business, other than property that is leased or
licensed, with respect to which the Company has valid and enforceable
leases or licenses under which there exists no default, event of default or
event which, with notice or lapse of time or both, would constitute a
default, except for such defaults which have not had or are not reasonably
likely to have, either individually or in the aggregate, a Material Adverse
Effect.

                  (a) All patents (including, without limitation, all U.S.

respect of Company Intellectual Property within twelve (12) months hereof.
All of the Company's patents, patent applications, registered trademarks,
trademark applications and registered copyrights are in good standing and,
except as would not have a Material Adverse Effect, all of the fees and

complete in all material respects.

                  (c) The Company Intellectual Property contains only those
items and rights which are: (i) owned by the Company; (ii) in the public
domain; or (iii) rightfully used by the Company pursuant to a valid and
enforceable license or other similar agreement (the "Company Licensed
Intellectual Property"). The Company has all rights in currently existing
Company Intellectual Property necessary to carry out their respective
current activities and their respective future activities to the extent
such future activities are already planned in a written business plan (and
had all rights necessary to carry out its former activities at the time
such activities were being conducted), including, to the extent required to
carry out such activities, rights to make, use, reproduce, modify, adopt,
create derivative works based on, translate, distribute (directly and
indirectly), transmit, display and perform publicly, license, rent and
lease and, other than with respect to Company Licensed Intellectual
Property, assign and sell, Company Intellectual Property.

                  (d) The reproduction, manufacturing, distribution,
licensing, sublicensing, sale or any other exercise of rights in any
Company Intellectual Property, product, work, technology or process as now
used or offered or proposed in a written business plan for use, licensing
or sale by the Company does not infringe on any rights in any patent,
design right, trademark, trade name, service mark, mask work, trade dress,
Internet domain name, copyright, database, statistical model, technology,
invention, supplier list, trade secret, know-how, computer software program
or application of any Person, anywhere in the world. No claims (i)
challenging the validity, effectiveness or, other than with respect to
Company Licensed Intellectual Property, ownership by the Company or any
Company Subsidiary of any Company Intellectual Property or (ii) to the
effect that the use, distribution, licensing, sublicensing, sale or any
other exercise of rights in any product, work, technology or process as now
used or offered or proposed in a written business plan for use, licensing,
sublicensing or sale by the Company or any Company Subsidiary or their
respective agents or use by its customers infringes or will infringe any
Intellectual Property or other proprietary right of any Person, have been
asserted or, to the Knowledge of the Company after due inquiry of those
individuals who would reasonably be expected to have information relevant
thereto, are threatened by any Person and the Company is unaware of the
existence of any facts which could reasonably support such a claim. To the
Knowledge of the Company after due inquiry of those individuals who would
reasonably be expected to have information relevant thereto, all of the
rights within Company Intellectual Property are enforceable and subsisting.
To the Knowledge of the Company after due inquiry of those individuals who
would reasonably be expected to have information relevant thereto, there is
no material unauthorized use, infringement or misappropriation of any
Company Intellectual Property by any third party, employee, former employee
or contract worker.

                  (e) Except in respect of the Persons referred to on
Section 3.11(e) of the Disclosure Schedule, all personnel, including
employees, contract workers, agents, consultants and contractors, who have
contributed to or participated in the conception and development of Company
Intellectual Property on behalf of the Company or any Company Subsidiary,
have executed proprietary inventions agreements in the form attached to
Section 3.11(e) of the Disclosure Schedule and either (i) have been a party
to an enforceable "work-for-hire" or similar agreement with the Company in
accordance with applicable national and state law that has accorded the
Company full, effective, exclusive and original ownership of all tangible
and intangible property thereby arising, or (ii) have executed appropriate
instruments of assignment in favor of the Company as assignee that have
conveyed to the Company effective and exclusive ownership of all tangible
and intangible property thereby arising. None of the Persons referred to in
Section 3.11(e) of the Disclosure Schedule as not having executed any of
the foregoing agreements, whether or not expressly named thereon, have
materially contributed to or participated in the conception or development
of Company Intellectual Property.

                  (f) The Company is not, nor as a result of the execution
or delivery of this Agreement, or performance of the Company's obligations
hereunder, will the Company be, in violation of any license, sublicense,
agreement or instrument involving Intellectual Property to which the
Company is a party or otherwise bound, nor will execution or delivery of
this Agreement, or performance of the Company's obligations hereunder,
cause the diminution, termination or forfeiture of the Company's rights in
any Company Intellectual Property.

                  (g) Section 3.11(g) of the Disclosure Schedule contains a
true and the complete list of all of the software programs included in or
developed for inclusion in the Company's products by the Company (including

Company's ability to account for, enforce its rights under, make use of,
understand or memorialize the Company Intellectual Property, the Company
has taken all reasonable steps, in accordance with normal industry
practice, to preserve and maintain notes and records relating to Company
Intellectual Property to cause the same to be readily understood,
identified and available.

                  (j) The Company Software Programs (i) have been designed
to ensure Year 2000 compatibility, which consists of data century
recognition, and calculations that accommodate same century and
multi-century formulas and date values; (ii) operate and will operate in
accordance with their specifications during and after the calendar Year
2000; (iii) have been designed to correctly recognize and process leap year

accrued prior to the Closing have been paid.

                  (n) The Company employs commercially reasonable measures
to ensure that the Company Software Programs contain no "viruses." For the
purposes of this Agreement, "virus" means any computer code intentionally
designed to disrupt, disable or harm in any manner the operation of any
software or hardware. To the Company's Knowledge, none of the foregoing
contains any worm, bomb, backdoor, clock, timer, or other disabling device,
code, design or routine which causes the software to be erased, inoperable,
or otherwise incapable of being used, either automatically or upon command
by any party.

                  (o) The Company has implemented commercially reasonable
steps for the physical and electronic protection of their respective
information assets from unauthorized disclosure, use or modification.
Section 3.11(o) of the Disclosure Schedule sets forth (i) each breach of
security involving its information assets of which the Company has
Knowledge, (ii) its known consequences and (iii) the steps the Company has

            3.13  Tax Matters.

                  (a) Filing of Timely Tax Returns. The Company has timely
filed all Tax Returns (as defined below) required to be filed by or on
behalf of it under applicable law. All such Tax Returns were and are true,
complete and correct. No claim has been made by a Taxing Authority (as
defined below), in a jurisdiction where the Company does not file Tax
Returns to the effect that the Company is or may be subject to taxation by
that jurisdiction, and to the Company's Knowledge, no reasonable basis
exists for such a claim to be made as to any prior period if such a claim
would involve a material Tax liability.

                  (b) Payment of Taxes. The Company has, within the time
and in the manner prescribed by law, paid all Taxes (as defined below) that
are due and payable by it.

                  (c) Tax Reserves. The total of the accrual and reserves
for Taxes (excluding deferred Taxes) on the balance sheets contained in the
Financial Statements is an amount at least equal to the sum of the
Company's liability for Taxes (other than Taxes previously paid over to the
appropriate Taxing Authority) for all Tax periods (and portions thereof)
ending on or before the date of such financial statements. Since the date
of the most recent Financial Statements, the Company has not incurred any
liability for Taxes other than in the ordinary course of business.

                  (d) Tax Liens. There are no Tax liens upon the assets,
properties or business of the Company except liens for Taxes not yet due or
being contested in good faith through appropriate proceedings and for which
adequate reserves have been established in the Financial Statements.

                  (e) Withholding Taxes. The Company and each Company
Subsidiary has complied in all material respects with the provisions of the
Code and all other applicable laws relating to information reporting and
returns and the payment and withholding of Taxes, including, without
limitation, the withholding and reporting requirements under Code Sections
1441 and 1464, 3401 through 3406 and 6041 through 6060, as well as similar
provisions under any other laws, and have, within the time and in the
manner prescribed by law, withheld and paid over to the proper Taxing
Authority all Taxes required to have been withheld and paid in
connection with amounts paid or owing to any employee, independent
contractor, creditor, stockholder, or other third party.

                  (f) Extensions of Time for Filing Tax Returns. The
Company has not requested any extension of time within which to file any
Tax Return, which Tax Return has not since been timely filed.

                  (g) Waivers of Statute of Limitations. The Company has
not executed any outstanding waivers or comparable consents regarding the
application of a statute of limitations with respect to any Taxes or Tax
Returns.

                  (h) Expiration of Statute of Limitations. Prior to the
date of this Agreement, the Company has provided the Buyer with written
schedules of (i) the Tax years of the Company for which any statute of
limitation with respect to any Tax has not expired and (ii) with respect to
any franchise Tax and any Tax based on net income, gross receipts or gross
income, for all Tax years of the Company for which the statutes of
limitations have not yet expired, those years for which examinations have
been completed, those years for which examinations are presently being
conducted and those years for which examinations have not yet been
initiated. To the Company's Knowledge, no deficiency for any Taxes has been
proposed, asserted or assessed against the Company that has not been
resolved and paid in full. To the Company's Knowledge, no facts exist that
would be reasonably likely to result in the assessment of any material
liability for Taxes against the Company for any prior periods for which Tax
Returns were or should have been filed.

                  (i) Audit, Administrative and Court Proceedings. No
audits or other proceedings by any Taxing Authority are presently pending,
or, to the Knowledge of the Company, threatened, with regard to any Taxes
or Tax Returns of the Company.

                  (j) Tax Ruling. The Company has not received or requested
a Tax Ruling (as defined below) or entered into a Closing Agreement (as
defined below) with any Taxing Authority. As used in this Agreement, "Tax
Ruling" shall mean any written ruling of (or other written guidance from) a
Taxing Authority relating to Taxes; and "Closing Agreement" shall mean a
written and legally binding agreement with a Taxing Authority relating to
Taxes.

                  (k) Availability of Tax Returns. Prior to the Effective
Time, the Company will make available to the Buyer complete and accurate
copies of (i) all Tax Returns for open years, and any amendments thereto,
filed by or on behalf of the Company, (ii) all audit reports or written
proposed adjustments (whether formal or informal) received from any Taxing
Authority relating to any Tax Return filed by or on behalf of the Company
and (iii) any Tax Ruling or request for a Tax Ruling applicable to the
Company and Closing Agreements entered into by the Company.

                  (l) Tax Sharing Agreements. The Company is not a party
to, is not bound by, and has no obligation under, any agreement relating to
the allocation of sharing of Taxes and has no liability for the Taxes of
any person other than the Company as a transferee, or successor or
otherwise (including, without limitation, any liability under Treasury
Regulation Section 1.1502-6 or any similar provision of state, local or
foreign law).

                  (m) Code Section 341(f). The Company has not filed (and
will not file prior to the Closing) a consent pursuant to Code Section
341(f) and has not agreed to have Code Section 341(f)(2) apply to any
disposition of a subsection (f) asset (as that term is defined in Code
Section 341(f)(4)) owned by the Company.

                  (n) Code Section 168. No property of the Company is
property that the Company or any party to this transaction is or will be
required to treat as being owned by another person pursuant to the
provisions of Code Section 168(f)(8) (as in effect prior to its amendment
by the Tax Reform Act of 1986) or is "tax-exempt use property" within the
meaning of Code Section 168(h).

                  (o) Code Section 481 Adjustments. The Company is not
required to include in income for any Tax period ending after the date
hereof any adjustment pursuant to Code Section 481(a) by reason of a
voluntary change in accounting method of the Company, nor has the IRS (as
defined below) proposed any such adjustment or change in accounting method.

                  (p) Acquisition Indebtedness. No indebtedness of the
Company is "corporate acquisition indebtedness" within the meaning of Code
Section 279(b) or an "applicable high yield discount obligation" within the
meaning of Code Section 163(i).

                  (q)  Consolidated Tax Returns.  The Company has never been
a member of an affiliated group of corporations (within the meaning of Code
Section 1504(a)) filing consolidated Tax Returns.

                  (r) United States Real Property Holding Company. The
Company has not been a United States real property holding company within
the meaning of Code Section 897(c)(2) during the applicable period
specified in Code Section 897(c)(1)(A)(ii).

either a "distributing corporation" or a "controlled corporation" (within
the meaning of Code Section 355(a)(1)(A)) in a distribution of stock
qualifying for tax-free treatment under Code Section 355(a), either (i) in
the two years prior to the date of this Agreement or (ii) in a distribution
that could otherwise constitute part of a "plan" or "series of related
transactions" (within the meaning of Code Section 355(e)) in conjunction
with the Merger.

                  (u) For purposes of this Agreement: (i) "Taxes"
(including, with correlative meaning, the word "Tax") shall include any and

awards, judgments, injunctions, decrees or other requirements of any court,
arbitrator or governmental or regulatory body against the Company. There is
no Litigation pending or, to the Knowledge of the Company, threatened

duly qualified or licensed as a foreign corporation to conduct business and
is in good standing under the laws of each jurisdiction in which the nature
of its business or the ownership or leasing of its properties requires such

reasonably be likely to, have a Buyer Material Adverse Effect. The Buyer
and each of its Subsidiaries has all requisite corporate power and
authority to own, lease and operate its assets and to carry on its business
as now being and as heretofore conducted.

applicable bankruptcy, insolvency, reorganization or similar laws now or
hereafter in effect relating to creditors' rights generally or to general

periods imposed by and receipt of all Permits or Orders indicated as
required in Section 4.3(c), the execution and delivery of this Agreement by
the Buyer and Sub does not (and, in the case of the Buyer, the execution

(and, in the case of the Buyer, thereunder) and the consummation by each of
the Buyer and Sub of the transactions contemplated hereby (and in the case
of the Buyer, thereby) will not, (i) conflict with, or result in any
violation or breach of any provision of the Amended and Restated
Certificate of Incorporation of the Buyer or the certificate of
incorporation of Sub, the by-laws of the Buyer or the by-laws of Sub, (ii)
result in any violation or breach of, or constitute (with or without notice

benefit) under any of the terms, conditions or provisions of any note,
bond, mortgage, indenture, lease, contract or other agreement, instrument
or obligation to which the Buyer or any of its Subsidiaries is a party or

Subsidiaries or any of its or their properties or assets, except, in the
case of (ii) and (iii), for any such violations, breaches, defaults,
terminations, cancellations, accelerations or conflicts which would not, in
the aggregate, have or result in a Buyer Material Adverse Effect.

registration, declaration or filing with, any Governmental Entity, is
required by or with respect to the Buyer or Sub in connection with the
execution and delivery by the Buyer or Sub of this Agreement or the Escrow

Effect.

omit to state a material fact required to be stated in such Buyer SEC
Reports or necessary in order to make the statements in such Buyer SEC

with GAAP applied on a consistent basis throughout the periods involved and
fairly presented the consolidated financial position of the Buyer and its
Subsidiaries as at the respective dates and the consolidated results of its

notes.

by the Buyer for inclusion in the Proxy Statement/Prospectus will not, on
the date the Proxy Statement/Prospectus is first mailed or otherwise

                        ADDITIONAL AGREEMENTS

            6.1  No Solicitation.

                  (a) During the period from the date of this Agreement
until the earlier of (i) the termination of this Agreement in accordance
with its terms and (ii) the Effective Time, the Company will not, directly
or indirectly, through any officer, director, employee, stockholder,
representative or agent of the Company (and the Company shall cause such
officers, directors, employees, stockholders, representatives and agents
not to, directly or indirectly), (i) solicit, initiate, facilitate or
encourage any inquiries or proposals that constitute, or could reasonably
be expected to lead to, a proposal or offer for a merger, consolidation,
business combination, sale of substantial assets (other than sales of
inventory in the ordinary course of business consistent with past
practice), sale of shares of capital stock or similar transactions
involving the Company, other than the transactions contemplated by this
Agreement (any of the foregoing inquiries or proposals being referred to in
this Agreement as an "Acquisition Proposal"), (ii) engage in negotiations
or discussions concerning, or provide any information concerning the
Company to any Person relating to, any Acquisition Proposal or (iii) agree
to, approve or recommend any Acquisition Proposal.

                  (b) The Company shall notify the Buyer immediately (and
no later than 24 hours) after receipt by the Company (or its advisors) of
any Acquisition Proposal or any request for information concerning the
Company in connection with an Acquisition Proposal or for access to the
properties, books or records of the Company by any Person that informs the
Company that it is considering making, or has made, an Acquisition
Proposal. Such notice to the Buyer shall be made orally and in writing and
shall indicate in reasonable detail the identity of the offeror and the
terms and conditions of such proposal, inquiry or contact. The Company
shall keep the Buyer informed in reasonable detail of all material
developments and the status of any Acquisition Proposal, or any request for
information in connection with any Acquisition Proposal or for access to
the properties, books or records of the Company by any person or entity
that is considering making, or has made, an Acquisition Proposal. The
Company shall provide the Buyer with copies of all documents received from
or delivered or sent to any person or entity that is considering making or
has made, an Acquisition Proposal.

            6.2  Approval of Stockholders; Proxy Statement/Prospectus; Blue
Sky.

                  (a) As promptly as practical after the execution of this
Agreement, the Company and the Buyer shall prepare, and the Buyer shall
file with the SEC, the Registration Statement and the Proxy
Statement/Prospectus to be included therein as a prospectus. The Company
and the Buyer shall use all reasonable efforts to respond to any comments
of the SEC and shall cause the Registration Statement to become effective
as soon after filing as practicable. The Company shall cause to be mailed
or otherwise provided to its stockholders the Proxy Statement/Prospectus as
soon as practicable after the Registration Statement is declared effective
by the SEC. The form of proxy to be executed by the Company Stockholders
shall be enclosed with the Proxy Statement/Prospectus. The Company
shall furnish the Buyer with all information concerning the Company and the
holders of Company Stock and shall take such other action as the Buyer may
reasonably request in connection with the Proxy Statement/Prospectus. In
addition, the Company agrees that the Proxy Statement/Prospectus, the form
of proxy and all other materials to be provided to the Company Stockholders
in connection with obtaining the Merger Stockholder Approval Actions shall
be subject to prior review of and approval by the Buyer and its counsel,
which shall not be unreasonably withheld. If at any time prior to the
Effective Time any event or circumstance relating to the Company, the
Buyer, Sub or any of their respective Affiliates, officers or directors
should be discovered by such party which should be set forth in an
amendment or a supplement to the Proxy Statement/Prospectus, such party
shall promptly inform the other thereof and take appropriate action in
respect thereof.

                  (b) Unless the Company shall have previously secured the
written consent of the Company Stockholders, in accordance with the DGCL
and the Certificate of Incorporation and the By-laws, approving and
adopting this Agreement, the Merger and the other transactions contemplated
hereby, the Company, acting through the Company Board, shall, in accordance
with the DGCL and the Certificate of Incorporation and the By-laws, as
promptly as practicable following the effectiveness of the Registration
Statement, duly call, give notice of, convene and hold, a special meeting
of the Company Stockholders to consider the approval and adoption of this
Agreement, the Merger and the other transactions contemplated hereby (the
"Company's Stockholders' Meeting"), and the Company shall consult with the
Buyer in connection therewith. The Company Board shall recommend the
approval and adoption of this Agreement, the Merger and the other
transactions contemplated hereby by the Company Stockholders and shall
include such recommendation in the Proxy Statement/Prospectus. The Company
shall use all reasonable efforts to solicit from the Company Stockholders
proxies or written consents in favor of the approval and adoption of this
Agreement, the Merger (including the appointment of the Stockholder
Representative) and the other transactions contemplated hereby and to
secure the vote, written consent or other written action of stockholders
required by the DGCL and the Certificate of Incorporation and the By-laws
to approve and adopt this Agreement, the Merger and the other transactions
contemplated hereby. Each of the Buyer and the Company shall prepare and
file as promptly as practicable any such other filings under the Exchange
Act, the Securities Act or the DGCL as may be required to effectuate the
Merger and the transactions contemplated by this Agreement. In the event
that the Company secures the written consent of the Company Stockholders
with respect to the approval and adoption of this Agreement, the Merger and
the other transactions contemplated hereby, the Company shall promptly
provide such notice to holders of shares of Company Stock entitled to
appraisal rights as required by the DGCL.

                  (c) The Buyer shall use all reasonable efforts to take
any action required to be taken under state securities or "blue sky" laws
in connection with the issuance of the shares of Buyer Common Stock in the
Merger.

            6.3 Access to Information. Upon reasonable notice, during
normal business hours during the period prior to the Effective Time, each
party shall (a) afford to the officers, directors, employees, accountants,
counsel and other representatives of the other party, reasonable access to
all its properties, plants, personnel, books, contracts, commitments and
records (other than privileged documents) and (b) all other information
concerning its business, properties and personnel as the other party may
reasonably request during such period. During such period, each party will
hold any such information which is non-public in confidence in accordance
with the Mutual Non-Disclosure Agreement, dated April 18, 2000, as amended
on May 27, 2000 (the "Confidentiality Agreement"), between the Buyer and
the Company. No information or knowledge obtained in any investigation
pursuant to this Section 6.3 shall affect or be deemed to modify any
representation or warranty contained in this Agreement or the conditions to
the obligations of the parties to consummate the Merger.

            6.4 Supplements to Disclosure Schedule. From time to time
prior to the Closing, the Company shall give prompt notice to the Buyer and
thereafter promptly supplement or amend the Disclosure Schedule with
respect to any matter hereafter arising which, if existing or occurring at
the date of this Agreement, would have been required to be set forth or
described in the Disclosure Schedule. No supplement or amendment of the
Disclosure Schedule made pursuant to this Section 6.4 shall be deemed to
cure any breach of any representation or warranty made in this Agreement,
or shall be taken into account in determining whether the condition to
Closing set forth in Section 7.2(a) hereof is satisfied as of the Closing
Date, unless the Buyer specifically agrees thereto in writing.

            6.5 Legal Conditions to Merger; Taking of Necessary Action.
Each of the Buyer and the Company will take all reasonable actions
necessary to comply promptly with all legal requirements which may be
imposed on either party with respect to the Merger (which actions shall
include, without limitation, furnishing all information required under the
HSR Act or in connection with approvals of or filings with any other
Governmental Entity) and will promptly cooperate with and furnish
information to each other in connection with any such requirements imposed
upon either of them in connection with the Merger. Each of the Buyer and
the Company will take (or cause to be taken) all reasonable actions
necessary to obtain (and will cooperate with each other in obtaining) any
consent, authorization, order or approval of, or any exemption by, any
Governmental Entity required to be obtained or made by the Buyer or the
Company in connection with the Merger or the taking of any action
contemplated thereby or by this Agreement. Subject to the terms and
conditions of this Agreement, each of the parties agrees to use reasonable
efforts to take, or cause to be taken, all action and to do, or cause to be
done, all things necessary, proper or advisable under applicable laws and
regulations to consummate and make effective the transactions contemplated
by this Agreement.

            6.6 Listing of Buyer Shares. The Buyer shall use reasonable
efforts to have authorized for listing on the Nasdaq National Market, upon
official notice of issuance, the shares of Buyer Common Stock to be issued
in the Merger and to be issued upon exercise of any Option assumed by the
Buyer pursuant to Section 6.7.

            6.7 Company Stock Plan. At the Effective Time, the Company
Stock Plan and each then outstanding Option, whether vested or unvested,
will be assumed by the Buyer and become and represent an option to acquire,
on the same terms and conditions (including, without limitation, vesting
provisions and repurchase provisions regarding any shares of restricted
stock) as were applicable to such Option prior to the Effective Time, a
number of shares of Buyer Common Stock (rounded down to the nearest whole
number) determined by multiplying (i) the number of shares of Common Stock
subject to such Option immediately prior to the Effective Time by (ii) the
Common Stock Exchange Ratio, at an exercise price per share (rounded up to
the nearest whole cent) equal to the exercise price per share of Common
Stock subject to such Option immediately prior to the Effective Time,
divided by the Common Stock Exchange Ratio. It is the intention of the
parties hereto that each Option so assumed by the Buyer will, to the extent
permitted by applicable laws, qualify as an "incentive stock option" within
the meaning of Section 422 of the Code to the extent such Option qualified
as such immediately prior to the Effective Time. As soon as practicable
after the Effective Time, the Buyer will deliver to each Person who,
immediately prior to the Effective Time, was a holder of an outstanding
Option, an instrument evidencing the assumption of such Option by the Buyer
as provided in this Section 6.7. The Buyer will take all corporate action
necessary to reserve for issuance a sufficient number of shares of Buyer
Common Stock for delivery upon exercise of Options assumed by the Buyer
pursuant to this Section 6.7. The Buyer will use reasonable efforts to
cause the issuance of shares of Buyer Common Stock issuable upon exercise
of any Options to have been registered as promptly as reasonably
practicable following the Effective Time pursuant to an effective
registration statement on Form S-8 under the Securities Act and to maintain
the effectiveness of such registration statement thereafter for so long as
any of such Options remain outstanding.

            6.8 Consents. Each of the Buyer and the Company shall use
reasonable efforts to obtain all necessary consents, waivers and approvals
under any of the Buyer's or the Company's material agreements, contracts,
licenses, leases or commitments in connection with the Merger.

            6.9 Further Action. In case at any time after the Effective
Time any further action is necessary or desirable and available to a party
to carry out the purposes of this Agreement or to vest the Surviving
Corporation with full title to all properties, assets, rights, approvals,
immunities and franchises of either of Sub or the Company, each party to
this Agreement shall take or cause to be taken all such action.

            6.10 Financial Statement Preparation and Review. Prior to the
Effective Time, the Company will use all reasonable efforts to cause its
respective management and independent auditors to facilitate on a timely
basis (i) the preparation of financial statements (including pro forma
financial statements to be prepared by the Buyer, if required) to comply or
enable the Buyer to comply with applicable SEC regulations, (ii) the review
of any audit or review work papers including the examination of selected
audited financial statements and data and (iii) the delivery of such
representations from each party's independent accountants as may be
reasonably requested by the other party or its accountants. The Company
will obtain a SAS 71 review of its unaudited financial statements as of
April 30, 2000 and for the four months then ended and any subsequent
interim financial statements prior to the Effective Time and provide copies
thereof to Buyer prior to the filing of the Registration Statement.


            6.11 Company Director and Officer Indemnification; Insurance.

                  (a) From and after the Effective Time, the Buyer will,
and will cause the Surviving Corporation to indemnify and hold harmless the
present and former officers, directors, employees and agents of the Company
in respect of acts or omissions occurring on or prior to the Effective Time
to the extent provided under the Certificate of Incorporation and the
By-laws, in each case as in effect on the date hereof; provided that such
indemnification shall be subject to any limitation imposed from time to
time under applicable law and shall not be available with respect to an
action initiated by an indemnification party (other than an action to
enforce this provision); and provided further that indemnification by the
Buyer pursuant to this Section 6.11 shall be provided only to the extent
any directors' and officers' liability insurance policy of the Company does
not provide coverage and actual payment. From the Effective Time and for a
period of four years thereafter, the certificate of incorporation and
by-laws of the Surviving Corporation shall contain provisions providing
rights to liability limitation, exculpation and indemnification in favor of
the employees, agents, directors or officers of the Company at least as
favorable as those currently included in the Certificate of Incorporation
and By-laws as in effect on the date hereof.

                  (b) The Surviving Corporation shall, and the Buyer shall
cause the Surviving Corporation to, maintain in effect for not less than
four years after the Effective Time the policies of directors' and
officers' liability insurance maintained by the Company as of the date
hereof for the benefit of those persons covered by such policies as of the
date hereof with respect to matters occurring prior to or at the Effective
Time; provided, however, that (i) the Surviving Corporation may substitute
therefor policies of at least the same coverage containing terms and
conditions which are no less advantageous to the insured persons with an
insurance company or companies, the claims paying ability of which is
substantially equivalent to the claims paying ability of the insurance
company or companies providing such insurance coverage as of the date
hereof for directors and officers of the Company and (ii) the Surviving
Corporation shall not be required to pay an annual premium for such
insurance in excess of two times the last annual premium paid prior to the
date hereof, but in such case shall purchase as much coverage as possible
for two times the last annual premium.

            6.12 Tax Treatment. From and after the date of this Agreement,
each Party shall use reasonable best efforts to cause the Merger to
qualify, and shall not knowingly take actions or cause actions to be taken
which could reasonably be expected to prevent the Merger from qualifying,
as a reorganization under Section 368(a) of the Code.

            6.13 Agreements with Respect to Affiliates.

                  (a) The Company will cause each person who is identified
in Section 3.29 of the Disclosure Schedule and any other person who, to the
Knowledge of the Company, is or becomes an "affiliate" of the Company for
purposes of Rule 145 under the Securities Act ("Rule 145") to deliver to
the Buyer, as soon as practicable but not later than thirty days after the
date hereof, a written agreement (a "Company Affiliate Agreement") in
connection with restrictions on affiliates under Rule 145 and pooling of
interests accounting treatment, substantially in the form of Exhibit A
hereto. The Company shall provide prompt notice to the Buyer of any such
other person who, to the Knowledge of the Company, is or becomes an
"affiliate" of the Company who is not identified in Section 3.29 of the
Disclosure Schedule.

                  (b) The Buyer will cause each person who, to the
Knowledge of the Buyer, is or may become an "affiliate" of the Buyer for
purposes of Rule 145, excluding all Subsidiaries of the Buyer, to deliver
to Buyer, a written agreement in connection with restrictions on affiliates
under pooling of interests accounting treatment, substantially in the form
of Exhibit B hereto.

            6.14 Pooling Accounting. The Buyer and the Company shall each
use reasonable best efforts to cause the business combination to be
effected by the Merger to be accounted for as a pooling of interests for
accounting purposes. Neither the Buyer nor the Company shall knowingly take
any action, or knowingly fail to take any action, that would be reasonably
likely to jeopardize the treatment of the Merger as a pooling of interests
for accounting purposes. The Buyer and the Company will use all reasonable
efforts to prevent any affiliate of such party from taking any actions
which could prevent the Merger from being treated for financial accounting
purposes as a "pooling of interests". Each of the Buyer and the Company
agrees to take such action as may be reasonably required to negate the
impact of any past actions which to its knowledge could be reasonably
likely to jeopardize the treatment of the Merger as a pooling of interests
for accounting purposes.

            6.15 Letters of Company Accountants. The Company shall use its
reasonable best efforts to cause to be delivered to the Buyer (i) a letter
of PricewaterhouseCoopers LLP, the Company's independent auditors, dated a
date within two business days before the date on which the Registration
Statement shall become effective and addressed to the Buyer, in form and
substance reasonably satisfactory to the Buyer and customary in scope and
substance for comfort letters delivered by independent public accountants
in connection with registration statements similar to the Registration
Statement, which letter shall be brought down to the Effective Time, and
(ii) the letter of PricewaterhouseCoopers LLP referred to in Section
7.2(i).

            6.16 Employee Matters.

                  (a) Employees of the Company whose employment with the
Company is continued by the Buyer, or who are retained as employees of the
Buyer, after the Effective Time, will receive salary and benefits
consistent with the Buyer's practices and policies in effect from time to
time.

                  (b) Prior to the Closing, the Company shall take all
necessary and appropriate action so that no amount payable under any
Company Employee Plan or Employee Agreement or otherwise will fail to be
deductible by the Company, Sub or the Buyer for U.S. federal income tax
purposes by virtue of Section 280G of the Code.

                  (c) The Company shall use its reasonable best efforts to
obtain from (i) each consultant (and each employee who formerly was a
consultant) a waiver to the effect that all work of such Person for the
Company will be deemed to be "work-for-hire" and (ii) a royalty-free
license to use any prior invention of any employee or consultant that is
incorporated into a product of the Company.

            6.17 Ancillary Agreements.  Concurrently with the Closing, the
Buyer and the Stockholder Representative will execute and deliver the Escrow
Agreement.

            6.18 Takeover Statutes. If any takeover statute is or may
become applicable to the transactions contemplated hereby, the Company
Board will grant such approvals and take such actions as are reasonably
necessary so that the transactions contemplated hereby may be consummated
as promptly as practicable on the terms contemplated hereby and otherwise
act to eliminate the effects of any takeover statute on any of the
transactions contemplated hereby.

            6.19 Employees. From and after the Effective Time, the Buyer
shall continue to employ individuals who are employed by the Company as of
the Effective Time who remain employed with the Buyer (the "Affected
Employees") at their salaries as in effect prior to the date hereof. The
Buyer shall use its reasonable efforts to ensure that as soon as
practicable after the Effective Time the Affected Employees, provided they
meet applicable eligibility requirements, are provided the opportunity to
participate in the Buyer's employee benefit plans, programs, policies or
arrangements that the Buyer provided to employees of the Buyer in positions
comparable to positions held by Affected Employees with the Buyer as of the
Effective Time.

            6.20 Alternative Transaction Structures. The Buyer and the
Company hereby acknowledge their mutual intent and agreement to further
consider following the date hereof alternative transaction structures and
registration procedures, including the delivery of the Merger Consideration
to the Company Stockholders in a manner which would not require
registration under the Securities Act, with the commitment of the Buyer to
register the shares of Buyer Common Stock to be issued in the Merger
subsequent to the Effective Time. The Company and the Buyer will use their
reasonable efforts to reach agreement as to any such alternative structures
or procedures which may be proposed and to negotiate an appropriate
amendment to this Agreement to effectuate the same.

            6.21 Working Capital Loan. In the event that prior to the
Effective Time the cash balances of the Company shall be reduced to less
than $5 million, provided that the Company's expenditures have been in the
ordinary course of business and the Company is not otherwise in material
breach of any of its representations, warranties or covenants in this
Agreement, the Buyer agrees to extend to the Company a working capital loan
of up to $15 million (with take downs in increments of $5 million) which
would be subordinate to the Company's existing bank borrowings and
otherwise on commercially reasonable terms.

efforts to have any such order, ruling or injunction vacated or lifted);

deemed applicable to the Merger which makes the consummation of the Merger
illegal.

                  (d)  Escrow Agreement.  The Buyer, the Stockholder
Representative and the Escrow Agent shall have executed and delivered the
Escrow Agreement.

opinion of Skadden, Arps, Slate, Meagher & Flom LLP, special tax counsel to
the Buyer, dated as of the Closing Date, substantially to the effect that
for U.S. federal income tax purposes the Merger will qualify as a
reorganization within the meaning of Section 368(a) of the Code and (ii)
the Company shall have received an opinion of Day, Berry & Howard LLP,
special tax counsel to the Company, dated as of the Closing Date,
substantially to the effect that for U.S. federal income tax purposes the

the receipt by such special tax counsel of representation letters from each
of the Buyer, Sub and the Company, in each case, in substantially the form
and substance attached hereto as Exhibit F and Exhibit G and in form and
substance reasonably satisfactory to such counsel, which letters shall not
have been modified or withdrawn. The opinions referred to in this Section
7.1(g) shall not be waivable after receipt of the Merger Stockholder

The obligations of the Buyer and Sub to effect the Merger are subject to
the satisfaction of each of the following conditions, any of which may be
waived in writing exclusively by the Buyer and Sub:

made and at and as of the Closing Date, as if made at and as of such time
(except to the extent such representations and warranties speak as of an
earlier date, in which case as of such date), except where the failure of
such representations and warranties to be so true and correct (without
giving effect to any limitations or qualifications as to "materiality" or
"Material Adverse Effect" set forth therein) would not be reasonably likely
to have, individually or in the aggregate, a Material Adverse Effect; and
the Buyer shall have received a certificate, signed on behalf of the
Company by the President and Chief Operating Officer of the Company, to
such effect.

                  (b) Performance of Obligations of the Company. The
Company shall have performed in all material respects all obligations
required to be performed by it under this Agreement at or prior to the
Closing Date; and the Buyer shall have received a certificate, signed on

Company, to such effect.

                  (c) No Litigation. There shall not be pending or
threatened in writing any suit, action or proceeding by any Governmental
Entity or other Person (i) seeking to prevent the consummation of the
Merger or seeking significant damages in connection therewith or (ii) which
otherwise is reasonably likely to have a Buyer Material Adverse Effect.

                  (d) Opinion. The Company shall have delivered to the
Buyer the opinion of Ropes & Gray or Day, Berry & Howard LLP, dated the
Closing Date, covering the matters set forth on Exhibit E hereto.

                  (e) Resignations. All officers and directors of the

of the Key Employees shall be in full force and effect, William Tao shall
have entered into a Key Employee Agreement and such agreement shall be in
full force and effect and no Key Employee shall have disavowed any such
agreement or otherwise indicated to the Company or the Buyer that such Key
Employee does not intend to continue or accept employment with the Company
or the Buyer after the Effective Time on the terms set forth in the Key
Employee Agreement with such Key Employee.

                  (h)  Escrow Agreement.  The Escrow Agreement shall have

a letter from PricewaterhouseCoopers LLP dated a date within two business
days of the Closing Date and addressed to the Buyer, stating that the
business combination to be effected by the Merger will qualify as a pooling
of interests transaction under generally accepted accounting principles.
The Company shall have received (and delivered to the Buyer copies of) a
letter from PricewaterhouseCoopers LLP, dated a date within two business
days of the Closing Date and addressed to the Company, stating that neither
the Company nor any Company Subsidiary has taken or agreed to take any
action that (without giving effect to this Agreement, the transactions
contemplated hereby, or any action taken or agreed to be taken by the Buyer
or any of its Subsidiaries) would prevent the Buyer from accounting for the
business combination to be effected by the Merger as a pooling of interests
transaction under generally accepted accounting principles.

                  (j) Affiliate Agreements. The Buyer shall have received
from each person who is identified in Section 3.29 of the Disclosure
Schedule or in any notice delivered by the Company to the Buyer pursuant to
Section 6.13 as an "affiliate" of the Company, a Company Affiliate
Agreement, and such Company Affiliate Agreement shall be in full force and
effect.

                  (k)  Termination of Company Stockholders' Agreement.  The
Company Stockholders' Agreement shall have been terminated.

                  (l) Dissenters. Unless the holders of greater than 95% of
the Common Stock issued and outstanding as of the Record Date have voted in
favor of the approval and adoption of this Agreement, the Merger and the
other transactions contemplated hereby, the period during which holders of
Common Stock may assert rights under Section 262 of the DGCL shall have
ended and not greater than 5% of the Common Stock issued and outstanding as
of the Record Date shall be Dissenting Shares in respect of which the
holder thereof has not forfeited, lost or withdrawn his or her right to
have the Company repurchase such shares pursuant to Section 262 of the
DGCL.

                  (m) Warrants and Equity Securities. All outstanding
Warrants and all rights to purchase equity securities pursuant to the Loan

and correct U.S. federal income Tax Return for its tax year ending December
31, 1999, and has filed all other material Tax Returns that are due on or
before the Closing Date (such due dates determined without regard to
extensions of time for filing such Tax Returns).

            7.3 Additional Conditions to Obligations of the Company. The
obligation of the Company to effect the Merger is subject to the
satisfaction of each of the following conditions, any of which may be
waived, in writing, exclusively by the Company:

                  (a) Representations and Warranties. The representations
and warranties of the Buyer set forth in this Agreement shall be true and

made and at and as of the Closing Date, as if made at and as of such time
(except to the extent such representations and warranties speak as of an
earlier date, in which case as of such date), except where the failure of
such representations and warranties to be so true and correct (without
giving effect to any limitations or qualifications as to "materiality" or
"Buyer Material Adverse Effect" set forth therein) would not be reasonably
likely to have, individually or in the aggregate, a Buyer Material Adverse
Effect; and the Company shall have received a certificate, signed on behalf
of the Buyer by the President and Chief Financial Officer of the Buyer, to
such effect.

                  (b) Performance of Obligations of the Buyer and Sub. The
Buyer and Sub shall have performed in all material respects all obligations
required to be performed by them under this Agreement at or prior to the

                                ARTICLE VIII

                        SURVIVAL AND INDEMNIFICATION

            8.1  Survival of Company Obligations.

                  (a) Subject to Section 8.3(a), the representations,
warranties, covenants and agreements of the Company in this Agreement shall
survive the Effective Time until the earlier to occur of (i) 5:00 p.m.,
Boston time, on the first anniversary of the Effective Time or (ii) the
date of issuance of the first independent audit report on the Buyer's
annual financial statements after the Effective Time, which annual
financial statements include the financial results of the Company.

                  (b) No investigation by, or furnishing of information to,
the Buyer shall affect the right of the Buyer to rely on the
representations, warranties, covenants and agreements of the Company set
forth herein.

            8.2  Company Stockholder Obligation to Indemnify.

                  (a) After the Effective Time, subject to Sections 8.1 and
8.3, the Company Stockholders shall indemnify and hold harmless the Buyer
and the Surviving Corporation and their respective directors, officers,
employees, agents, affiliates and assigns (collectively, the "Buyer
Indemnified Persons") from and against all losses, liabilities, damages,
deficiencies, costs or expenses, including interest and penalties imposed
or assessed by any judicial or administrative body and reasonable
attorneys' fees, whether or not arising out of third-party claims and
including all amounts paid in investigation, defense or settlement of the
foregoing, net of any actual recoveries under existing insurance policies,
amounts actually received pursuant to indemnification from third parties or
in the case of third party claims, by any amount actually recovered by the
party or parties seeking indemnification or their Affiliates pursuant to
counterclaims made by any of them directly relating to facts giving rise to
such third-party claims (collectively, "Losses"), suffered or incurred by
any Buyer Indemnified Person based upon, arising out of or otherwise in
respect of any inaccuracy in or breach of any representation or warranty
(for purposes of this Section 8.2, disregarding, in determining the
existence of a misrepresentation or breach of warranty, any requirement in
a representation or warranty that an event or fact be material or have, or
be reasonably likely to have, a Material Adverse Effect, in order for such
event or fact to constitute a misrepresentation or breach of warranty), or
any breach of any covenant or agreement, of the Company in this Agreement
or any certificate of the Company delivered pursuant to the terms hereof.

                  (b) No indemnification shall be payable pursuant to
Section 8.2(a) with respect to any inaccuracy or breach of any
representation or warranty or breach of any covenant or agreement after
termination thereof in accordance with Section 8.1, except with respect to
claims made prior to such termination pursuant to Section 8.5 but not then
resolved (such representation, warranty, covenant or agreement surviving
with respect to such claim until resolution of such claim).

                  (c) The terms and conditions of this Article VIII
constitute essential terms and conditions of this Agreement and the Merger,
and approval of the Merger by the Company Stockholders shall constitute the
express agreement of each Company Stockholder with respect to (i) the
obligations of the Company Stockholders pursuant to this Article VIII and
(ii) the appointment of G. Felda Hardymon to act as the representative of
the Company Stockholders pursuant to the terms and conditions of this
Agreement and the Escrow Agreement. Without limitation of the foregoing, as
an essential term of this Agreement and the Merger, the Company
Stockholders acknowledge that their indemnification obligations are solely
in their capacity as former stockholders of the Company, and, accordingly,
an obligation to indemnify any Buyer Indemnified Person pursuant to this
Section 8.2 shall not itself cause any current or former officer, director,
employee or agent of the Company to be entitled to any indemnification from
the Company pursuant to the Certificate of Incorporation, the By-laws or
any agreement with the Company.

            8.3 Limitations on Company Stockholder Indemnification.

                  (a) The limitations of Sections 8.2(b), 8.3(b), 8.3(c),
8.3(d) and 8.3(e) shall not apply in the case of a fraudulent or
intentional misrepresentation by the Company. Notwithstanding the
foregoing, in no event shall the liability of any Company Stockholder
exceed the value of the Merger Shares paid to such Company Stockholder in
the Merger, including the value of the Escrow Shares included in Merger
Shares paid to such Company Stockholder in the Merger.

                  (b) The Company Stockholders shall have no
indemnification obligation pursuant to Section 8.2 unless and until the
aggregate amount of Losses incurred or suffered by the Buyer Indemnified
Persons exceeds $1,000,000, after which, subject to Sections 8.3(c) and
8.3(d), the obligation of the Company Stockholders shall be to indemnify
the Buyer Indemnified Persons for the entire amount of such Losses
(including such initial $1,000,000).

                  (c) The indemnification obligations of the Company
Stockholders pursuant to Section 8.2 shall be several, and not joint, in
proportion to their respective Ownership Percentage Interests as set forth
on the Closing Stockholder Schedule referred to in Section 2.1(g).

                  (d) The Escrow Shares shall be the sole and exclusive
recourse of the Buyer Indemnified Persons to satisfy the indemnification
obligations of the Company Stockholders pursuant to Section 8.2(a), and the
Company Stockholders shall have no further obligation to indemnify the
Buyer Indemnified Persons pursuant to Section 8.2(a) after all the Escrow
Shares have been redelivered to the Buyer pursuant to the Escrow Agreement.
For purposes of satisfying the indemnification obligations of the Company
stockholders, the Escrow Shares shall be valued at $84.5705 per share,
subject to appropriate adjustment for splits, combinations and the like
affecting Buyer Common Stock.

                  (e) After the Effective Time, subject to Section 8.3(a),
this Article VIII shall set forth the sole and exclusive remedy and
recourse of the Buyer Indemnified Persons with respect to any
representation, warranty, covenant or agreement of the Company contained
herein.

            8.4  Nonsurvival of Buyer Obligations.  The representations and
warranties of the Buyer in this Agreement shall terminate and be of no further
force or effect as of the Effective Time.

            8.5  Procedures Relating to Indemnification.

                  (a) An indemnified person or entity under Section 8.2 (an
"Indemnified Party") shall give prompt written notice to the Stockholder
Representative (as defined in Section 8.6), as agent for the Company
Stockholders, with a copy to the Escrow Agent of any claim or event known
to it which gives rise or, in its reasonable judgment, may give rise to a
claim for indemnification hereunder by the Indemnified Party against the
Company Stockholders; provided that the failure of any Indemnified Party to
give notice as provided in this Section 8.5 shall not relieve the Company
Stockholders of their obligations under this Article VIII, except to the
extent that such failure has materially and adversely affected the rights
of the Company Stockholders. In the case of any claim for indemnification
hereunder arising out of a claim, action, suit or proceeding brought by any
person who is not a Party to this Agreement (a "Third-Party Claim"), the
Indemnified Party shall also give the Stockholder Representative, as agent
for the Company Stockholders, copies of any written claims, process or
legal pleadings with respect to such Third-Party Claim promptly after such
documents are received by the Indemnified Party.

                  (b) Except as otherwise provided in paragraph (c) below,
the Indemnified Parties shall be entitled to control the defense of any
Third-Party Claim; provided, however, that the Stockholder Representative,
as agent for the Company Stockholders, may elect, at the Company
Stockholders' own cost and expense, to participate in any Third-Party
Claim; provided further, however, that neither the Stockholder
Representative nor any Company Stockholder shall take any action with
respect to such Third-Party Claim before consulting with, and receiving the
consent of, each Indemnified Party involved. If the Stockholder
Representative, as agent for the Company Stockholders, elects to
participate in a Third-Party Claim, the Stockholder Representative shall,
within 30 days of its receipt of the notice provided pursuant to Section
8.5(a) hereof (or sooner, if the nature of such Third-Party Claim so
requires), notify the related Indemnified Party of its intent to do so. The
Stockholder Representative and each Company Stockholder shall reasonably
cooperate in the compromise of, or defense against, such Third-Party Claim.
The Company Stockholders shall be responsible for the payment of each
Indemnified Party's costs and expenses incurred in connection with such
cooperation, and such expenses shall constitute Losses incurred or suffered
by the Buyer within the meaning of Section 8.2 hereof. The Indemnified
Party shall not consent to entry of any judgment or enter into any
settlement without the prior written consent of the Stockholder
Representative, as agent for the Company Stockholders, which consent shall
not be unreasonably withheld.

                  (c) If the Indemnified Party elects not to compromise or
defend against a Third-Party Claim, the Stockholder Representative, on
behalf of the Company Stockholders shall pay, compromise or defend such
Third-Party Claim at the Company Stockholders own cost and expense. The
Stockholder Representative shall, within thirty days (or sooner, if the
nature of such Third-Party Claim so requires), notify the Indemnified Party
of its intent to pay, compromise or defend such Third-Party Claim, and such
Indemnified Party shall reasonably cooperate in the compromise of, or
defense against, such Third-Party Claim. The Company Stockholders shall be
responsible for the payment of the Indemnified Parties' costs and expenses
incurred in connection with such cooperation, and such costs and
expenses shall constitute Losses incurred or suffered by the Buyer within
the meaning of Section 8.2 hereof. Neither the Stockholder Representative
nor any Company Stockholder shall consent to entry of any judgment or enter
into any settlement without the prior written consent of each related
Indemnified Party (which consent shall not be unreasonably withheld),
unless such judgment or settlement provides solely for money Losses or
other money payments for which such Indemnified Party is entitled to
indemnification hereunder and includes as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnified Party of a release
from all liability in respect of such Third-Party Claim; provided that the
Stockholder Representative shall not be entitled to settle any claim,
action, suit or proceeding brought by a Taxing Authority in respect of
Taxes for any Pre-Closing Period that would have the effect of materially
decreasing the Company's deductions for credits or materially increasing
the Company's taxable income for any taxable year or period subsequent to
the Pre-Closing Period without the prior written consent of the Buyer,
which consent shall not be unreasonably withheld. After notice from the
Stockholder Representative, as agent for the Company Stockholders, to an
Indemnified Party of its election to assume the defense of a Third-Party
Claim, the Company Stockholders shall not be liable to such Indemnified
Party under this Article VIII for any legal expenses subsequently incurred
by such Indemnified Party in connection with the defense thereof; provided
that such Indemnified Party shall have the right to employ one counsel of
its choice to represent such Indemnified Party if, in such Indemnified
Party's reasonable judgment, a conflict of interest between such
Indemnified Party and the Company Stockholders exists in respect of such
claim, or if there is a reasonable likelihood that a Third-Party Claim may
have a material adverse effect on an Indemnified Party, and in that event
the reasonable fees and expenses of such separate counsel shall be the
responsibility of the Company Stockholders (and shall constitute Losses
incurred or suffered by the Buyer within the meaning of Section 8.2(a)
hereof).

            8.6 Stockholder Representative.

                  (a) In order to administer the transactions contemplated
by this Agreement and the Escrow Agreement, including the indemnification
obligations of the Company Stockholders under this Article VIII, the
Company Stockholders hereby designate and appoint G. Felda Hardymon as
their sole and exclusive representative for purposes of this Agreement and
the Escrow Agreement and as attorneys-in-fact and agent for and on behalf
of each Company Stockholder (in such capacity, the "Stockholder
Representative"), and G. Felda Hardymon accepts such appointment as
Stockholder Representative.

                  (b) The Company Stockholders hereby authorize the
Stockholder Representative to represent the Company Stockholders, and their
successors, with respect to all matters arising under this Agreement and
the Escrow Agreement, including without limitation, (i) to take all action
necessary in connection with the indemnification obligations of the
Stockholders under this Article VIII, including the defense or settlement
of any claims and the making of payments with respect thereto, (ii) to give
and receive all notices required to be given by or to any Company
Stockholder under this Agreement and the Escrow Agreement, (iii) to execute
the Escrow Agreement for and on behalf of the Company Stockholders, and
(iv) to take any and all additional action as is contemplated to be taken
by or on behalf of the Company Stockholders by the Stockholder
Representative pursuant to this Agreement and the Escrow Agreement.

                  (c) In the event that G. Felda Hardymon or any substitute
Stockholder Representative dies, becomes unable to perform his
responsibilities as Stockholder Representative or resigns from such
position, the Company Stockholders having an aggregate Ownership Percentage
Interest as set forth on the Closing Stockholder Schedule referred to in
Section 2.1(g) greater than 50% shall select another representative to fill
such vacancy and such substituted Stockholder Representative shall be
deemed to be the Stockholder Representative for all purposes of this
Agreement and the Escrow Agreement.

                  (d) All decisions and actions by the Stockholder
Representative, including without limitation any agreement between the
Stockholder Representative and the Buyer or the Escrow Agent relating to
indemnification obligations of the Stockholders under this Article VIII,
including the defense or settlement of any claims and the making of
payments with respect hereto, shall be binding upon all of the Company
Stockholders, and no Company Stockholders shall have the right to object,
dissent, protest or otherwise contest the same. The Stockholder
Representative shall incur no liability to the Company Stockholders with
respect to any action taken or suffered by the Stockholder Representative
in reliance upon any notice, direction, instruction, consent, statement or
other documents believed by him to be genuinely and duly authorized, nor
for any other action or inaction with respect to the indemnification
obligations of the Company Stockholders under this Article VIII, including
the defense or settlement of any claims and the making of payments with
respect thereto, except to the extent resulting from the Stockholder
Representative's own willful misconduct or gross negligence. The
Stockholder Representative may, in all questions arising under this
Agreement or the Escrow Agreement rely on the advice of counsel, and shall
not be liable to the Company Stockholders for anything done, omitted or
suffered in good faith by the Stockholder Representative. The Company
Stockholders shall severally indemnify the Stockholder Representative and
hold him or her harmless against any loss, liability or expense incurred
without gross negligence or bad faith on the part of the Stockholder
Representative and arising out of or in connection with the acceptance or
administration of his or her duties hereunder.

                  (e) The Buyer and the Escrow Agent shall be able to rely
conclusively on the instructions and decisions of the Stockholder
Representative with respect to the indemnification obligations of the
Company Stockholders under this Article VIII, including the defense or
settlement of any claims or the making of payments with respect thereto, or
as to any other actions required or permitted to be taken by the
Stockholder Representative hereunder, and no party hereunder shall have any
cause of action against the Buyer or the Escrow Agent to the extent the
Buyer or the Escrow Agent has relied upon the instructions or decisions of
the Stockholder Representative.

                  (f) The Company Stockholders acknowledge and agree that
the Stockholder Representative may incur costs and expenses on behalf of
the Company Stockholders in his capacity as Stockholder Representative
("Representative Expenses"). Each of the Company Stockholders agrees to pay
the Stockholder Representative, promptly upon demand by the Stockholder
Representative therefor, a percentage of any Representative Expenses equal
to such Company Stockholder's Ownership Percentage Interest as set forth on
the Closing Stockholder Schedule referred to in Section 2.1(g), provided
that no Company Stockholder shall be required to pay, in the aggregate,
Representative Expenses in an amount in excess of the value of such Company
Stockholder's Ownership Percentage Interest in the Escrow Shares initially
deposited in escrow pursuant to Section 2.3(b) (valuing the Escrow Shares
for this purpose at $84.5705 per share, subject to splits, combinations and
the like affecting Buyer Common Stock).

                  (b) by the Buyer or the Company if the Merger shall not
have been consummated by November 30, 2000, provided that the right to

pursuant to this Section 9.1(c) shall have complied with its obligations
under Section 6.5 and used reasonable efforts to have any such order,
ruling, injunction or other action vacated or lifted);

                  (d) by the Buyer, if (i) any Company Stockholder party to
the Voting Agreement breaches the Voting Agreement (without limitation of
other actions or failures to act by any Company Stockholder that may
constitute a breach of the Voting Agreement, such Company Stockholder will

does not vote in favor of the approval and adoption of this Agreement, the
Merger and the other transactions contemplated hereby at the Company's
Stockholders' Meeting with respect to all of such Company Stockholder's
Company Stock or if such Company Stockholder transfers any of such Company

takes any action prohibited by or otherwise breaches Section 6.1; or (iii)

other party (and which breach would result in the condition to Closing in
Section 7.2(a), 7.2(b), 7.3(a) or 7.3(b), as the case may be, not being
satisfied).

            9.2 Effect of Termination. In the event of termination of this
