     Section 2.1  STATUTORY MERGER.  Subject to the terms and conditions and 
in reliance upon the representations, warranties, covenants and agreements 
contained herein, Newco will merge with and into the Company at the Effective 
Time.  The terms and conditions of the Merger and the mode of carrying the 
same into effect will be as set forth in this Agreement.  As a result of the 
Merger, the separate corporate existence of Newco will cease and the Company 
will continue as the Surviving Corporation and shall succeed to and assume 
all of the rights and obligations of Newco in accordance with the DGCL.  The 
Merger shall have the effect set forth in the DGCL.

     Section 2.2  EFFECTIVE TIME.  As soon as practicable after the 
satisfaction or, if permissible, waiver of the conditions set forth in 
Article VIII, the parties hereto will cause the Merger to be consummated by 
filing a certificate of merger (the "Certificate of Merger") with the 
Secretary of State of the State of Delaware, in such form as required by, and 
executed in accordance with the relevant provisions of, the DGCL.  The Merger 
shall become effective at the time at which the Certificate of Merger has 
been duly filed with the Secretary of State of the State of Delaware (the 
time the Merger becomes effective in accordance with the foregoing being 
referred to as the "Effective Time").

     Section 2.3  CERTIFICATE OF INCORPORATION; BYLAWS.  At the Effective Time,
the certificate of incorporation of the Company shall be amended and restated 
by deleting its provisions and substituting therefore the provisions of the 
certificate of incorporation of Newco except that from and after the Effective 
Time Article First of the certificate of incorporation will read in its 

                                       7
<PAGE>
entirety substantially as follows:  The name of the corporation is "Netscape 
Communications Corporation."  At the Effective Time, the by-laws of Newco, as 
in effect immediately prior to the Effective Time, shall be the by-laws of 
the Surviving Corporation until thereafter amended as provided by Law and the 
certificate of incorporation of the Surviving Corporation and such by-laws.

     Section 2.4  DIRECTORS AND OFFICERS.  The directors of Newco immediately 
prior to the Effective Time will be the directors of the Surviving 
Corporation, each to hold office in accordance with the certificate of 
incorporation and by-laws of the Surviving Corporation, and the officers of 
the Company immediately prior to the Effective Time will be the officers of 
the Surviving Corporation, in each case until their respective successors are 
duly elected or appointed and qualify for such election.

                                     ARTICLE III

                  CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

     Section 3.1  MERGER CONSIDERATION; CONVERSION AND CANCELLATION OF 
SECURITIES.  At the Effective Time, by virtue of the Merger and without any 
action on the part of the holders of any of the following securities:

             (a)  Subject to the other provisions of this Article III, each 
share of Company Common Stock issued and outstanding immediately prior to the 
Effective Time (excluding any Company Common Stock described in Section 
3.1(c)) will be converted into the right to receive 0.45 (the "Exchange 
Ratio") shares of Acquiror Common Stock (the "Merger Consideration"). 
Notwithstanding the foregoing, if between the date of this Agreement and the 
Effective Time the outstanding shares of Acquiror Common Stock or Company 
Common Stock shall have been changed into a different number of shares or a 
different class, by reason of any stock dividend, subdivision, 
reclassification, recapitalization, split, conversion, consolidation, 
combination or exchange of shares, the Exchange Ratio will be correspondingly 
adjusted to reflect such stock dividend, subdivision, reclassification, 
recapitalization, split, conversion, consolidation, combination or exchange 
of shares.

             (b)  Subject to the other provisions of this Article III, all 
shares of Company Common Stock will, upon conversion thereof into shares of 
Acquiror Common Stock at the Effective Time, cease to be outstanding and will 
automatically be cancelled and retired, and each certificate previously 
evidencing Company Common Stock outstanding immediately prior to the 
Effective Time (other than Company Common Stock described in Section 3.1(c)) 
will thereafter represent only the right to receive (i) the number of whole 
shares of Acquiror Common Stock  and (ii) as provided in Section 3.2(e), cash 
in lieu of fractional shares into which the shares of Company Common Stock 
represented by such certificate have been converted pursuant to this Section 
3.1(b).  The holders of certificates previously evidencing Company Common 
Stock  will cease to have any rights with respect to such Company Common 
Stock except as otherwise provided herein or by Law.

                                       8
<PAGE>
             (c)  Notwithstanding any provision of this Agreement to the 
contrary, each share of Company Common Stock held in the treasury of the 
Company and each share of Company Common Stock, if any, owned by Acquiror or 
any direct or indirect wholly owned Subsidiary of Acquiror or of the Company 
immediately prior to the Effective Time will be cancelled.

             (d)  Each share of common stock, par value $.01 per share, of 
Newco issued and outstanding immediately prior to the Effective Time shall be 
converted into and become one fully paid and nonassessable share of common 
stock, par value $.01 per share, of the Surviving Corporation.

     Section 3.2  EXCHANGE OF CERTIFICATES.

             (a)  EXCHANGE FUND.  On the day of the Effective Time, Acquiror 
will deposit, or cause to be deposited, with the Exchange Agent, for the 
benefit of the former holders of Company Common Stock, for exchange in 
accordance with this Article III, through the Exchange Agent, certificates 
representing shares of Acquiror Common Stock issuable pursuant to Section 3.1 
in exchange for certificates representing Company Common Stock immediately 
prior to the Effective Time (such shares of Acquiror Common Stock so 
deposited, together with cash realized and held by the Exchange Agent for the 
benefit of such former holders of Company Common Stock in accordance with 
Section 3.2(e), being referred to as the "Exchange Fund").  Thereafter, 
Acquiror will deposit, or cause to be deposited, with the Exchange Agent, for 
the benefit of any former holders of Company Common Stock who have not yet 
surrendered their shares of Company Common Stock  for exchange, at the 
appropriate payment date, the amount of dividends or other distributions, 
with a record date after the Effective Time but prior to surrender, payable 
with respect to any shares of Acquiror Common Stock remaining in the Exchange 
Fund on such record date.  The Exchange Agent will, pursuant to irrevocable 
instructions from Acquiror, deliver Acquiror Common Stock and any such 
dividends or distributions related thereto, in exchange for certificates 
theretofore evidencing Company Common Stock surrendered to the Exchange Agent 
pursuant to Section 3.2(c).

             (b)  LETTER OF TRANSMITTAL.  Promptly after the Effective Time, 
Acquiror will cause the Exchange Agent to mail to each record holder of a 
certificate or certificates representing Company Common Stock immediately 
prior to the Effective Time (i) a letter of transmittal which shall specify 
that delivery shall be effected, and risk of loss and title to the 
certificates formerly representing Company Common Stock shall pass, only upon 
delivery of such certificates to the Exchange Agent and shall be in such form 
and have such other provisions, including appropriate provisions with respect 
to back-up withholding, as Acquiror may reasonably specify, and (ii) 
instructions for use in effecting the surrender of the certificates formerly 
representing Company Common Stock.  Upon surrender of a certificate formerly 
representing Company Common Stock for cancellation to the Exchange Agent, 
together with such letter of transmittal, duly executed and completed in 
accordance with the instructions thereto, the holder thereof shall be 
entitled to receive in exchange therefor that portion of the Exchange Fund 
which such holder has the right to receive pursuant to the provisions of this 
Article III, after giving effect to any required withholding Tax, and the 
certificate formerly 

                                       9
<PAGE>
representing Company Common Stock so surrendered shall forthwith be 
cancelled.  No interest will be paid or accrued on the cash to be paid which 
is in the Exchange Fund.

             (c)  EXCHANGE PROCEDURES.  Promptly after the Effective Time, 
the Exchange Agent will distribute to each former holder of Company Common 
Stock, upon surrender to the Exchange Agent for cancellation of one or more 
certificates, accompanied by a duly executed letter of transmittal that 
theretofore evidenced shares of Company Common Stock, certificates evidencing 
the appropriate number of shares of Acquiror Common Stock into which such 
shares of Company Common Stock were converted pursuant to the Merger and any 
dividends or distributions related thereto which such former holder of 
Company Common Stock is entitled to receive pursuant to the provisions of 
this Article III.  If shares of Acquiror Common Stock are to be issued to a 
Person other than the Person in whose name the surrendered certificate or 
certificates are registered, it will be a condition of issuance of Acquiror 
Common Stock  that the surrendered certificate or certificates shall be 
properly endorsed, with signatures guaranteed by a member firm of the New 
York Stock Exchange or a bank chartered under the Laws of the United States, 
or otherwise in proper form for transfer and that the Person requesting such 
payment shall pay any transfer or other Taxes required by reason of the 
issuance of Acquiror Common Stock  to a Person other than the registered 
holder of the surrendered certificate or certificates or such Person shall 
establish to the satisfaction of Acquiror that any such Tax has been paid or 
is not applicable. Notwithstanding the foregoing, neither the Exchange Agent 
nor any party hereto will be liable to any former holder of Company Common 
Stock for any Acquiror Common Stock or cash or dividends or distributions 
thereon delivered to a public official pursuant to any applicable escheat Law.

             (d)  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES OF COMPANY 
COMMON STOCK. No dividends or other distributions declared or made with 
respect to Acquiror Common Stock on or after the Effective Time will be paid 
to the holder of any certificate that theretofore evidenced shares of Company 
Common Stock until the holder of such certificate shall surrender such 
certificate.  Subject to the effect of any applicable escheat Law, following 
surrender of any such certificate, there will be paid from the Exchange Fund 
to the holder of the certificates evidencing whole shares of Acquiror Common 
Stock issued in exchange therefor, without interest, (i) promptly, the amount 
of dividends or other distributions with a record date after the Effective 
Time theretofore paid with respect to such whole shares of Acquiror Common 
Stock, and (ii) at the appropriate payment date, the amount of dividends or 
other distributions, with a record date after the Effective Time but prior to 
surrender and a payment date occurring after surrender, payable with respect 
to such whole shares of Acquiror Common Stock.

             (e)  NO FRACTIONAL SHARES.

                  (i)    No certificates or scrip representing fractional 
shares of Acquiror Common Stock shall be issued upon the surrender for 
exchange of certificates formerly representing shares of Company Common Stock 
pursuant to this Article III; no dividend, stock split or other change in the 
capital structure of Acquiror shall relate to any fractional security; and 
such fractional interests shall not entitle the owner thereof to vote or to 
any rights of a security holder.

                                       10
<PAGE>
                  (ii)    As promptly as practicable following the Effective 
Time, the Exchange Agent will determine the excess of (A) the number of whole 
shares of Acquiror Common Stock delivered to the Exchange Agent by Acquiror 
pursuant to Section 3.2(a) over (B) the aggregate number of whole shares of 
Acquiror Common Stock to be distributed to holders of Company Common Stock 
pursuant to Section 3.2(c) (such excess being herein called the "Excess 
Shares"). Following the Effective Time, the Exchange Agent will, on behalf of 
former stockholders of the Company, sell the Excess Shares at then-prevailing 
prices on the New York Stock Exchange, Inc. (the "NYSE"), all in the manner 
provided in Section 3.2(e)(iii).

                 (iii)   The sale of the Excess Shares by the Exchange Agent 
will be executed on the NYSE through one or more member firms of the NYSE and 
will be executed in round lots to the extent practicable.  The Exchange Agent 
will use reasonable efforts to complete the sale of the Excess Shares as 
promptly following the Effective Time as, in the Exchange Agent's sole 
judgment, is practicable consistent with obtaining the best execution of such 
sales in light of prevailing market conditions.  Until the net proceeds of 
such sale or sales have been distributed to the holders of Company Common 
Stock, the Exchange Agent will hold such proceeds in trust for the former 
holders of Company Common Stock (the "Common Shares Trust").  The Surviving 
Corporation will pay all commissions, transfer taxes and other out-of-pocket 
transaction costs, including the expenses and compensation of the Exchange 
Agent incurred in connection with such sale of the Excess Shares.  The 
Exchange Agent will determine the portion of the Common Shares Trust to which 
each former holder of Company Common Stock is entitled, if any, by 
multiplying the amount of the aggregate net proceeds comprising the Common 
Shares Trust by a fraction, the numerator of which is the amount of the 
fractional share interest to which such former holder of Company Common Stock 
is entitled (after taking into account all shares of Company Common Stock 
held at the Effective Time by such holder) and the denominator of which is 
the aggregate amount of fractional share interests to which all holders of 
Company Common Stock are entitled.  For purposes of this Section 3.2(e), 
shares of Company Common Stock of any former holder represented by two or 
more certificates may be aggregated and in no event shall any holder be paid 
an amount of cash in respect of more than one share of Acquiror Common Stock.

                  (iv)    As soon as practicable after the determination of 
the amount of cash, if any, to be paid to the former holders of Company 
Common Stock with respect to any fractional share interests, the Exchange 
Agent will hold such cash amounts for the benefit of, and pay such cash 
amounts to, such former holders of Company Common Stock subject to and in 
accordance with the terms of Section 3.2(c).

             (f)  TERMINATION OF EXCHANGE FUND.  Any portion of the Exchange 
Fund which remains unclaimed by the former holders of Company Common Stock 
for twelve months after the Effective Time will be delivered to Acquiror, 
upon demand, and any former holders of Company Common Stock who have not 
theretofore complied with this Article III will, subject to applicable 
abandoned property, escheat and other similar Laws, thereafter look only to 
Acquiror for Acquiror Common Stock and any cash to which they are entitled.

                                       11
<PAGE>
             (g)  WITHHOLDING OF TAX.  Acquiror or the Exchange Agent will be 
entitled to deduct and withhold from the consideration otherwise payable 
pursuant to this Agreement to any former holder of Company Common Stock such 
amounts as Acquiror (or any Affiliate thereof) or the Exchange Agent are 
required to deduct and withhold with respect to the making of such payment 
under the Code, or any provision of state, local or foreign Tax Law.  To the 
extent that amounts are so withheld by Acquiror or the Exchange Agent, such 
withheld amounts will be treated for all purposes of this Agreement as having 
been paid to the former holder of Company Common Stock in respect of whom 
such deduction and withholding was made by Acquiror.

             (h)  LOST CERTIFICATES.  If any certificate evidencing Company 
Common Stock shall have been lost, stolen or destroyed, upon the making of an 
affidavit of that fact by the Person claiming such certificate to be lost, 
stolen or destroyed and, if required by Acquiror, the posting by such Person 
of a bond, in such reasonable amount as Acquiror may direct, as indemnity 
against claims 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 of Acquiror Common Stock to which the holder may be entitled 
pursuant to this Article III and cash and any dividends or other 
distributions to which the holder thereof may be entitled pursuant to Section 
3.2(d) or Section 3.2(e).

     Section 3.3  CLOSING.  The Closing will take place at the offices of 
Skadden, Arps, Slate, Meagher & Flom LLP, One Beacon Street, 31st Floor, 
Boston, Massachusetts at 10:00 a.m. on the second Business Day following the 
date on which the conditions to the Closing have been satisfied or waived or 
at such other place, time and date as the parties hereto may agree.  At the 
conclusion of the Closing on the Closing Date, the parties hereto will cause 
the Certificate of Merger to be filed with the Secretary of State of the 
State of Delaware.

     Section 3.4  STOCK TRANSFER BOOKS.  At the Effective Time, the stock 
transfer books of the Company will be closed and there will be no further 
registration of transfers of shares of Company Common Stock thereafter on the 
records of the Company.  If, after the Effective Time, certificates formerly 
representing Company Common Stock are presented to the Surviving Corporation, 
they shall be cancelled and exchanged for certificates representing Acquiror 
Common Stock.

                                      ARTICLE IV

individually or together, have good, valid and marketable title to or a valid

the Company and its Subsidiaries as it is currently being conducted, 
including all of the properties and assets reflected in the Company's

as part of its report on Form 10-Q, other than any such properties or assets 
that have been sold or otherwise disposed of in the ordinary course of 
business since July 31, 1998.  None of such properties are securities pledged 
for interest rate swap, cap or floor contracts.  The Company or its 
Subsidiaries, individually or together, hold under valid lease agreements all 
real and personal properties being held by the Company or its Subsidiaries

other than (i) any properties as to which such leases have expired in

Property).

its terms, except (a) that the enforcement thereof may be limited by (i) 
bankruptcy, insolvency, reorganization, moratorium or other similar Laws now 
or hereafter in effect relating to creditors' rights generally and (ii) 
general principles of equity (regardless of whether enforceability is 
considered in a proceeding in equity or at law) and (b) as would not, 
individually or in the aggregate, materially adversely impact any Business 
Segment.  No condition exists or event has occurred which (whether with or 
without notice or lapse of time or both, or the happening or occurrence of 
any other event) would constitute a default by the Company or a Subsidiary 
or, to the Knowledge of the Company, any other party thereto under, or result 
in a right in termination of, any Material Contract, except as would not,

the Company's stockholders to consider the Merger (the "Company Stockholders' 
Meeting") (such proxy statement/prospectus, as amended or supplemented, is 
referred to herein as the "Proxy Statement") shall not, on the date the Proxy 
Statement is first mailed to the Company's stockholders, at the time of the 
Company Stockholders' Meeting and at the Effective Time, contain any

information supplied by Acquiror or required to be supplied by the Acquiror

substitution for, shares outstanding on the date hereof.  In no event shall

restricted Company Common Stock granted or issued under any Company Plan be 
accelerated as a result of or in connection with the execution, delivery or 
performance of this Agreement, the Option Agreement or the Voting Agreement 
or the consummation of the transactions contemplated hereby and thereby, 
except to the extent required under the terms of the applicable Company Plan 
or applicable individual agreement as in effect on the date hereof (or if

                                ADDITIONAL AGREEMENTS

     Section 7.1  NO SOLICITATION.  From the date hereof until the Effective 
Time or, if earlier, the termination of this Agreement pursuant to Article 
IX, the Company shall not (whether directly or indirectly through advisors, 
agents or other intermediaries), and the Company shall cause its respective 
officers, directors, advisors, representatives or other agents of the Company 
not to, (a) solicit, initiate or knowingly encourage any Acquisition Proposal 
(as defined herein) or (b) engage in discussions or negotiations with, or 
disclose any non-public information relating to the Company or its 
Subsidiaries or afford access to the properties, books or records of the 
Company or its Subsidiaries to, any Person that has made an Acquisition 
Proposal or has advised the Company that it is interested in making an 
Acquisition Proposal; PROVIDED that, if and only if (i) the Company's Board 
of Directors believes in good faith, based on such matters as it deems 
relevant, including the advice of the Company's financial advisor, that such 
Acquisition Proposal is a Financially Superior Proposal (as defined herein) 
and (ii) the Company's Board of Directors determines in good faith, based on 
such matters as it deems relevant, including consultation with the Company's 
outside legal counsel, that the failure to

                                       33

<PAGE>

engage in such negotiations or discussions or provide such information is a 
breach of the fiduciary duties of the Board of Directors of the Company under 
applicable Law, then the Company may engage in any act otherwise proscribed 
by clause (b) above.  The Company shall as promptly as practicable provide 
Acquiror with a copy of any written Acquisition Proposal received and a 
written statement with respect to any nonwritten Acquisition Proposal 
received, which statement shall include the identity of the Person making the 
Acquisition Proposal and the material terms thereof.  The Company shall 
inform Acquiror as promptly as practicable of any change in the price, 
structure, form of consideration or material terms and conditions regarding 
the Acquisition Proposal.  For purposes of this Agreement, "Acquisition 
Proposal" means any offer or proposal for a merger, consolidation, 
recapitalization, liquidation or other business combination involving the 
Company or any of its Material Subsidiaries (as defined herein) or the 
acquisition or purchase of 20% or more of any class of equity securities of 
the Company or any of its Material Subsidiaries, or any tender offer or 
exchange offer, that, if consummated, would result in any Person (other than 
Acquiror and its affiliates) beneficially owning 20% or more of any class of 
equity securities of the Company or any of its Material Subsidiaries, or the 
acquisition, license or purchase of a substantial portion of the technology, 
business or assets of the Company and its Subsidiaries, other than the 
transactions contemplated by this Agreement and other than in the ordinary 
course of business.  As used herein, a "Financially Superior Proposal" shall 
mean an Acquisition Proposal which in the reasonable judgment of the 
Company's Board of Directors, based on such matters as it deems relevant, 
including the advice of the Company's financial advisor, (i) will result in a 
transaction providing aggregate value greater than that provided pursuant to 
this Agreement and (ii) is reasonably capable of being financed by the Person 
making such Acquisition Proposal.  As used herein, "Material Subsidiary" 
means any Subsidiary of the Company whose consolidated revenues, net income 
or assets constitute 20% or more of the revenues, net income or assets of the 
Company and its Subsidiaries, taken as a whole.  Nothing in this Agreement, 
including Section 6(g), shall prohibit the Company or the Company's Board of 
Directors from taking and disclosing to the Company's stockholders a position 
with respect to a tender or exchange offer by a third party pursuant to Rules

cause its Subsidiaries to, (i) afford to the other party and its officers, 
directors, employees, accountants, consultants, legal counsel, agents and 
other representatives (collectively, the "Representatives") full access at 
reasonable times upon reasonable prior notice to the officers, employees,

other party and its Representatives such information concerning the business,

Board of Directors, shall, in accordance with the DGCL and its certificate of 
incorporation and bylaws, promptly and duly call, give notice of, convene and 
hold as soon as practicable following the date upon which the Registration 
Statement becomes effective, the Company Stockholders' Meeting, and the 
Company shall consult with Acquiror in connection therewith. Unless the Board 
of Directors determines, based on such matters as it deems relevant, 
including consultation with the Company's outside legal counsel, that to do 
so is a breach of the fiduciary duties of the Board of Directors of the 
Company under applicable Law, the Board of Directors of the Company shall 
declare that this Agreement is advisable and recommend that the Agreement and 
the transactions contemplated hereby be approved and adopted by the 
stockholders of the Company and include in the Registration Statement and 
Proxy Statement a copy of such recommendations; PROVIDED, HOWEVER, that, the 
Board of Directors of the Company shall submit this Agreement to the 
Company's stockholders, whether or not the Board of Directors of the Company 
at any time subsequent to the date hereof determines that this Agreement is 
no longer advisable or recommends that the stockholders of the Company reject 
it.  Unless the Board of Directors of the Company has withdrawn its 
recommendation of this Agreement in compliance herewith, the Company shall 
use reasonable efforts to solicit from stockholders of the Company proxies in 
favor of the approval and adoption of this Agreement and the Merger and to 
secure the vote or consent of stockholders required by the DGCL and its 
certificate of incorporation and bylaws to approve and adopt this Agreement 
and the Merger.

          (a)    As promptly as practicable following the date of this 
Agreement, the Company shall prepare and file with the SEC a preliminary 
proxy or information statement relating to the Merger and this Agreement and 
obtain and furnish the information required to be included by the SEC in the 
Proxy Statement and, after consultation with Acquiror, respond promptly to 
any comments made by the SEC with respect to the Proxy Statement to be mailed

consultation with Acquiror and its counsel.

          (b)    Acquiror shall prepare and file with the SEC the 
Registration Statement, in which the Proxy Statement shall be included as a 
prospectus, and shall use reasonable efforts to have the Registration 
Statement declared effective by the SEC as promptly as practicable. Acquiror 
shall obtain and furnish the information required to be included in the 
Registration Statement and, after consultation with the Company, respond

or supplement thereto, to be mailed to the Company's stockholders at the 
earliest practicable date after the Registration Statement is declared 
effective

                                      35

by the SEC, provided that no amendment or supplement to the Registration 
Statement will be made by Acquiror without consultation with the Company and 
its counsel.  Acquiror shall also take any action required to be taken under 
state blue sky or other securities Laws in connection with the issuance of 
Acquiror Common Stock in the Merger.

     Section 7.5 APPROPRIATE ACTION; CONSENTS; FILINGS.

          (a)    The Company and Acquiror will each use reasonable efforts 
(i) to take, or to cause to be taken, all appropriate action, and to do, or 
to cause to be done, all things necessary, proper or advisable under 
applicable Law or otherwise to consummate and make effective the transactions 
contemplated by this Agreement, unless the Board of the Directors of the 
Company has withdrawn its recommendation of this Agreement in compliance 
herewith, (ii) to obtain from any Governmental Authorities any Permits or 
Orders required to be obtained by Acquiror or the Company or any of their 
Subsidiaries in connection with the authorization, execution, delivery and 
performance of this Agreement and the consummation of the transactions 
contemplated hereby, including the Merger, (iii) to make all necessary

this Agreement and the Merger required under (A) the Securities Act and the 
Exchange Act, and any other applicable federal or state securities Laws, (B) 
the HSR Act (C) Foreign Competition Laws and (D) any other applicable Law; 
PROVIDED that Acquiror and the Company will cooperate with each other in 
connection with the making of all such filings, including providing copies of 
all such documents to the nonfiling party and its advisors prior to filings 
and, if requested, will accept all reasonable additions, deletions or changes 
suggested in connection therewith and (iv) to furnish all information 
required for any application or other filing to be made pursuant to any 
applicable Law or any applicable Regulations of any Governmental Authority 
(including all information required to be included in the Proxy Statement or 
the Registration Statement) in connection with the transactions contemplated 
by this Agreement PROVIDED, HOWEVER, that neither Acquiror nor any of its 
Affiliates shall be under any obligation to make proposals, execute or carry 
out agreements or submit to Orders providing for the sale or other 
disposition or holding separate (through the establishment of a trust or 
otherwise) of any material (in nature or amount) assets or categories of 
material (in nature or amount) assets of Acquiror, any of its Affiliates or 
the Company or the holding separate of the shares of Company Common Stock or 
imposing or seeking to impose any material limitation on the ability of 
Acquiror or any of its Subsidiaries or Affiliates to conduct their business 
or own such assets or to acquire, hold or exercise full rights of ownership 
of the shares of Company Common Stock.

          (b)    Each of the Company and Acquiror will give prompt notice to 
the other of (i) any notice or other communication from any Person alleging 
that the consent of such Person is or may be required in connection with the 
Merger, (ii) any notice or other communication from any Governmental 
Authority in connection with the Merger, (iii) any Litigation, relating to or 
involving or otherwise affecting the Company, Acquiror or their Subsidiaries 
that relates to the consummation of the Merger; and (iv) any change that is 
reasonably likely to have a Material Adverse Effect on the Company or 
Acquiror.

                                      36
<PAGE>

          (c)    Each of the Company and Acquiror will give (or will cause 
their respective Subsidiaries to give) any notices to third Persons, and use, 
and cause their respective Subsidiaries to use, reasonable efforts to obtain 
any consents from third Persons necessary, proper or advisable (as determined 
in good faith by Acquiror with respect to such notices or consents to be 
delivered or obtained by the Company) to consummate the transactions 
contemplated by this Agreement.

          (d)    To the extent requested by Acquiror, the Company shall 
cooperate with Acquiror to identify any "Encumbrances" that may adversely 
affect the Company's or its Subsidiaries' right to sublicense any 
Intellectual Property rights owned or licensed by the Company (including the 
right to further sublicense such rights) in the Company's or its 
Subsidiaries' client or server software (including without limitation 
development tools, tests and other development components) which will exist 
as of the Closing Date, and any maintenance upgrades and new releases of such 
software, if any, which will be already in progress at the Company as of the 
Closing Date, and/or any components of the foregoing (collectively, the 
"Software Products").  Such cooperation shall include, upon Acquiror's 
written request, granting Acquiror full access, subject to existing or other 
reasonable confidentiality restrictions, to the Company's technology 
licenses, acquisition agreements and Intellectual Property claims relating to 
the Software Products.  "Encumbrance" means any restriction or limit that 
would prevent or materially limit or restrict the Company's ability to 
sublicense any Intellectual Property right owned or licensed by the Company 
(including the right to further sublicense such rights) with respect to the 
Software Products, including, without limitation, limitations on source code 
access and sublicensing rights, as well as prohibitions or required consents 
to assignment of rights from the Company to the Acquiror upon the Closing 
Date, which rights, if not available, would constitute an Encumbrance.  The 
Company shall use reasonable efforts in consultation with Acquiror to remove, 
limit or diminish such Encumbrances in a reasonable priority order designated 
by Acquiror, with the goal of removing or minimizing as soon as practicable 
all such Encumbrances and having no ongoing financial obligations in 
connection therewith. 

     Section 7.6 AFFILIATES; POOLING; TAX TREATMENT.

          (a)    The Company will use reasonable efforts to obtain an 
executed letter agreement substantially in the form of ANNEX C hereto from 
(i) each Person identified in Section 4.22 of the Company's Disclosure 
Schedule within 15 days following the execution and delivery of this 
Agreement and (ii) from any Person who, to the Company's Knowledge, may be 
deemed to have become an Affiliate of the Company after the date of this 
Agreement and prior to the Effective Time as soon as practicable after 
attaining such status.

          (b)    Acquiror will use reasonable efforts to obtain an executed 
letter agreement substantially in the form of ANNEX D hereto from (i) each 
Person identified in Section 5.11 of Acquiror's Disclosure Schedule within 15 
days following the execution and delivery of this Agreement and (ii) from any 
Person who, to Acquiror's Knowledge, may be

                                      37
<PAGE>

deemed to have become an Affiliate of Acquiror after the date of this 
Agreement and prior to the Effective Time as soon as practicable after 
attaining such status.

          (c)    Acquiror Companies will not be required to maintain the 
effectiveness of the Registration Statement for the purpose of resale by 
stockholders of the Company who may be Affiliates of the Company pursuant to 
Rule 145 under the Securities Act.

          (d)    Acquiror and the Company will each use reasonable efforts 
before and after the Closing to cause the Merger to qualify as a 
reorganization within the meaning of Section 368(a) of the Code, and will not 
take, and will use reasonable efforts to prevent any Affiliate of such party 
from taking, any actions which could prevent the Merger from qualifying as 
such a reorganization, and will take such action as is available and may be 
reasonably required to negate the impact of any past actions by such party or 
its respective Affiliates which would reasonably be expected to adversely 
impact the qualification of the Merger as a reorganization within the meaning 
of Section 368(a) of the Code.  Acquiror and the Company will each use 
reasonable efforts to obtain executed representation letters described in 
Sections 8.2(d) and 8.3(c), respectively, substantially in the respective 
forms attached hereto as Annexes E and F.

          (e)    (i)     Acquiror will not knowingly take, or knowingly 
permit any controlled Affiliate of Acquiror to take, any actions which could 
prevent the Merger from being treated for financial accounting purposes as a 
"pooling of interests" under GAAP, it being understood and agreed that if 
Ernst & Young LLP, Acquiror's independent accountants, advises Acquiror that 
an action would not prevent the Merger from being so treated, such action 
will be conclusively deemed not to constitute a breach of this Section 7.6 
(e)(i).

                 (ii)    The Company will not knowingly take, or knowingly 
permit any controlled Affiliate of the Company to take, any actions which 
could prevent the Merger from being treated for financial accounting purposes 
as a "pooling of interests" under GAAP, it being understood and agreed that 
if Ernst & Young LLP, the Company's independent accountants, advises the 
Company that an action would not prevent the Merger from being so treated, 
such action will be conclusively deemed not to constitute a breach of this 
Section 7.6 (e)(ii).

     Section 7.7 PUBLIC ANNOUNCEMENTS.  The parties will consult with each 
other and will mutually agree upon any press release or public announcement 
pertaining to the Merger and shall not issue any such press release or make 
any such public announcement prior to such consultation and agreement, except 
as may be required by applicable Law or by obligations pursuant to any 
listing agreement with any national securities exchange or national automated 
quotation system, in which case the party proposing to issue such press 
release or make such public announcement shall use reasonable efforts to 
consult in good faith with the other party before issuing any such press 
release or making any such public announcement.  Notwithstanding the 
foregoing, in the event the Company's Board of Directors withdraws its 
recommendation of this Agreement in compliance herewith, the Company will no 
longer be

                                      38
<PAGE>

required to consult with or obtain the agreement of Acquiror or Newco in 
connection with any press release or public announcement.

     Section 7.8 STOCK EXCHANGE LISTING.  Acquiror will use reasonable 
efforts to cause the shares of Acquiror Common Stock to be issued in the 
Merger to be approved for listing (subject to official notice of issuance) on 
the New York Stock Exchange prior to the Effective Time. 

     Section 7.9 EMPLOYEE BENEFIT PLANS.

          (a)    Acquiror agrees that individuals who are employed by the 
Company or any Subsidiary of the Company immediately prior to the Effective 
Time shall become employees of the Surviving Corporation or one of its 
Subsidiaries following the Effective Time (each such employee, an "Affected 
Employee"); PROVIDED, HOWEVER, that this Section 7.9(a) shall not be 
construed to limit the ability of the applicable employer to terminate the 
employment of any Affected Employee at any time.

          (b)    Acquiror will, or will cause the Surviving Corporation to, 
give Affected Employees full credit for purposes of eligibility (including 
service and waiting period requirements), vesting, benefit accrual and 
determination of the level of benefits under any employee benefit plans or 
arrangements maintained by the Acquiror, the Surviving Corporation or any 
Subsidiary of the Acquiror for such Affected Employees' service with the 
Company or any Subsidiary of the Company to the same extent recognized by the 
Company or any Subsidiary of the Company immediately prior to the Effective 
Time.

          (c)    Acquiror will, or will cause the Surviving Corporation to, 
(i) waive all limitations as to preexisting conditions, exclusions and 
waiting periods and service requirements with respect to participation and 
coverage requirements applicable to the Affected Employees under any welfare 
benefit plans that such employees may be eligible to participate in after the 
Effective Time, other than limitations, waiting periods or service 
requirements that are already in effect with respect to such employees and 
that have not been satisfied as of the Effective Time under any welfare plan 
maintained for the Affected Employees immediately prior to the Effective 
Time, and (ii) provide each Affected Employee with credit for any co-payments 
and deductibles paid prior to the Effective Time (as shown on the Company's 
records) in satisfying any applicable deductible or out-of-pocket 
requirements under any welfare plans that such employees are eligible to 
participate in after the Effective Time.

          (d)    For a period of six months immediately following the 
Effective Time, the coverage and benefits provided to Affected Employees 
pursuant to employee benefit plans or arrangements maintained by Acquiror, 
the Company or any Subsidiary of the Company, or any Subsidiary of the 
Acquiror shall be, in the aggregate, not less favorable than those provided 
to such employees immediately prior to the Effective Time.

     Section 7.10   INDEMNIFICATION OF DIRECTORS AND OFFICERS; DIRECTORS & 
OFFICERS INSURANCE.  

          (a)    From and after the Effective Time, Acquiror will fulfill and 
honor and will cause the Surviving Corporation to fulfill and honor in all 
respects the obligations of the Company pursuant to any indemnification 
agreements between the Company and its directors and officers as of or prior 
to the date hereof (or indemnification agreements in the Company's customary 
form for directors joining the Company's Board of Directors prior to the 
Effective Time) and any indemnification provisions under the Company's 
certificate of incorporation or bylaws as in effect immediately prior to the 
Effective Time.

          (b)    For a period of six years after the Effective Time, Acquiror 
will maintain or cause the Surviving Corporation to maintain in effect, if 
available, directors' and officers' liability insurance covering those 
Persons who, as of immediately prior to the Effective Time, are covered by 
the Company's directors' and officers' liability insurance policy (the 
"Insured Parties") on terms no less favorable to the Insured Parties than 
those of the Company's present directors' and officers' liability insurance 
policy; PROVIDED, HOWEVER, that in no event will Acquiror or the Surviving 
Corporation be required to expend in excess of 150% of the annual premium 
currently paid by the Company for such coverage (or such coverage as is 
available for 150% of such annual premium).

          (c)    The provisions of this Section 7.10 are intended to be for 
the benefit of, and will be enforceable by, each Person entitled to 
indemnification hereunder and the heirs and representatives of such Person.  
Acquiror will not permit the Surviving Corporation to merge or consolidate 
with any other Person unless the Surviving Corporation will ensure that the 
surviving or resulting entity assumes the obligations imposed by this Section 
7.10.

     Section 7.11   EVENT NOTICES.  From and after the date of this Agreement 
until the Effective Time, each party hereto will promptly notify the other 
party hereto of (i) the occurrence or nonoccurrence of any event the 
occurrence or nonoccurrence of which would be likely to cause any condition 
to the obligations of such party to effect the Merger and the other 
transactions contemplated by this Agreement not to be satisfied and (ii) the 
failure of such party to comply with any covenant or agreement to be complied 
with by it pursuant to this Agreement which would be likely to result in any 
condition to the obligations of such party to effect the Merger and the other 
transactions contemplated by this Agreement not to be satisfied. No delivery 
of any notice pursuant to this Section 7.11 will cure any breach of any 
representation or warranty of such party contained in this Agreement or 
otherwise limit or affect the remedies available hereunder to the party 
receiving such notice.

     Section 7.12   ASSUMPTION OF OBLIGATIONS TO ISSUE STOCK.

          (a)    Simultaneously with the Merger, (i) each outstanding option 
or warrant to purchase or acquire a share of Company Common Stock under any 
Company Option Plan or otherwise shall, in accordance with the terms thereof, 
be converted into an option or warrant to purchase the number of shares of 
Acquiror Common Stock equal to the Exchange Ratio times the number of shares 
of Company Common Stock which could have been obtained prior to the Effective 
Time upon the exercise of each such option or warrant (rounded down to the 
nearest whole share), at an exercise price per share equal to the exercise 
price for each such share of Company Common Stock (rounded up to the nearest 
whole cent) subject to such option or warrant divided by the Exchange Ratio, 
and all references in each such option or warrant to the Company shall be 
deemed to refer to Acquiror, where appropriate, and (ii) Acquiror shall 
assume the obligations of the Company under the Company Option Plans.  The 
other terms of each such option or warrant and any Company Option Plans under 
which they were issued, shall continue to apply in accordance with their 
terms, including any provisions providing for acceleration.

          (b)    Simultaneously with the Merger, each outstanding award 
(including restricted stock, stock equivalents and stock units) ("Company 
Award") under any employee incentive or benefit plans, programs or 
arrangements presently maintained by the Company or any Company Subsidiary 
which provide for grants of equity-based awards shall be amended or converted 
into a similar instrument of Acquiror, in each case with such adjustments to 
the terms of such Company Awards as are appropriate to preserve the value 
inherent in such Company Awards with no detrimental effects on the holders 
thereof.  The other terms of each Company Award, and the plans or agreements 
under which they were issued, shall continue to apply in accordance with 
their terms, including any provisions providing for acceleration.

          (c)    The Company and Acquiror agree that each of their respective 
employee incentive or benefit plans, programs and arrangements shall be 
amended, to the extent necessary and appropriate, to reflect the transactions 
contemplated by this Agreement, including, but not limited to the conversion 
of shares of Company Common Stock held or to be awarded or paid pursuant to 
such benefit plans, programs or arrangements into shares of Acquiror Common 
Stock on a basis consistent with the transactions contemplated by this 
Agreement.

          (d)    Acquiror shall (i) reserve for issuance the number of shares 
of Acquiror Common Stock that will become subject to the benefit plans, 
programs, arrangements and warrants referred to in this Section 7.12 and (ii) 
issue or cause to be issued the appropriate number of shares of Acquiror 
Common Stock pursuant to such plans, programs, arrangements and warrants, 
upon the exercise or maturation of rights existing thereunder at the 
Effective Time or thereafter granted or awarded.

          (e)    The parties will use their reasonable efforts to mutually 
agree with respect to the treatment of the Company Stock Purchase Plan in the 
Merger on terms not

                                      41
<PAGE>

inconsistent with the Company Stock Purchase Plan or the terms of this 
Agreement; provided, however, that in no event may Company Common Stock be 
purchased under the Company Stock Purchase Plan after the Effective Time.

          (f)    Acquiror agrees to file a registration statement on Form S-8 
for the shares of Acquiror Common Stock issuable with respect to options 
under any Company Option Plan at or prior to the Effective Time and shall use 
its commercially reasonable efforts to maintain the effectiveness of such 
registration statement thereafter for as long as any of such options remain 
outstanding, to the same extent as Acquiror maintains the effectiveness of 
its existing Form S-8.

          (g)    The Company hereby assigns all Repurchase Rights to the 
Surviving Corporation as of the Effective Time.

     Section 7.13   CONVEYANCE TAXES.  Acquiror and the Company shall 
cooperate in the preparation, execution and filing of all returns, 
questionnaires, applications, or other documents regarding (i) any real 
property transfer gains, sales, use, transfer, value-added, stock transfer 
(subject to Section 3.2(c)), and stamp Taxes (ii) any recording, registration 
and other fees, and (iii) any similar Taxes or fees that become payable in 
connection with the transactions contemplated hereby.  The Taxes described in 
clause (i) above shall be paid by the Company.

     Section 7.14   VOTING AGREEMENT.  The Company shall use reasonable 
efforts, on behalf of Acquiror and pursuant to the request of Acquiror, to 
cause each Company stockholder named on the signature pages to the Voting 
Agreement to execute and deliver to Acquiror the Voting Agreement 
concurrently with the execution of this Agreement.

     Section 7.15   OPTION AGREEMENT.  Concurrently with the execution of 
this Agreement, the Company shall deliver to Acquiror an executed Option 
Agreement in the form of ANNEX B attached hereto.  The Company agrees to 
fully perform to the fullest extent permitted under applicable Law its 
obligations under the Option Agreement.

     Section 7.16   RIGHTS AGREEMENT.  The Company covenants and agrees with 
Acquiror that the Company shall not take any action which would cause (A) a 
"Shares Acquisition Date" to occur, or Acquiror or any of its Affiliates, 
individually or taken together, to be or be deemed to be an "Acquiring 
Person" under the Company Rights Agreement, or (B) the Company Rights 
Agreement or the Company Rights to apply to Acquiror or any of its 
Affiliates, individually or taken together, in the case of (A) or (B), solely 
as a result of this Agreement, the Option Agreement, the Voting Agreement or 
the transactions contemplated hereby and thereby.  The Company agrees to take 
all actions as are required to prevent any event described in (A) or (B) from 
occurring, in any such case solely as a result of this Agreement, the Option 
Agreement, the Voting Agreement or the transactions contemplated hereby and 
thereby.

     Section 7.17   REASONABLE EFFORTS AND FURTHER ASSURANCES.  Subject to 
the terms and conditions hereof, each of the parties to this Agreement shall 
use reasonable efforts to effectuate

                                      42
<PAGE>

the transactions contemplated hereby and to fulfill and cause to be fulfilled 
the conditions to Closing under this Agreement.  Subject to the terms and 
conditions hereof, each party hereto, at the reasonable request of another 
party hereto, shall execute and deliver such other instruments and do and 
perform such other acts and things as may be necessary or desirable for 
effecting completely the consummation of this Agreement and the transactions 
contemplated hereby.

                                     ARTICLE VIII

                                  CLOSING CONDITIONS

     Section 8.1 CONDITIONS TO OBLIGATIONS OF EACH PARTY UNDER THIS 
AGREEMENT.  The respective obligations of each party to effect the Merger and 
the other transactions contemplated hereby will be subject to the 
satisfaction at or prior to the Effective Time of the following conditions, 
any or all of which may be waived by the party entitled to the benefit 
thereof, in whole or in part, to the extent permitted by applicable Law:

          (a)    EFFECTIVENESS OF THE REGISTRATION STATEMENT.  The 
Registration Statement shall have become effective in accordance with the 
provisions of the Securities Act; no stop Order suspending the effectiveness 
of the Registration Statement shall be in effect; and no proceedings for that 
purpose shall be pending before or threatened by the SEC.

          (b)    STOCKHOLDER APPROVAL.  This Agreement and the Merger shall 
have been approved and adopted by the requisite vote of the stockholders of 
the Company in accordance with the DGCL and the certificate of incorporation 
and bylaws of the Company.

          (c)    NO ORDER.  No Court or Governmental Authority having 
jurisdiction over the Company or Acquiror shall have enacted, issued, 
promulgated, enforced or entered any Law, Regulation or Order (whether 
temporary, preliminary or permanent) which is then in effect and which has 
the effect of making the Merger illegal or otherwise prohibiting consummation 
of the Merger substantially on the terms contemplated by this Agreement.

          (d)    REGULATORY APPROVALS.  All approvals and consents of 
applicable Courts and/or Governmental Authorities required to consummate the 
Merger shall have been received, and all applicable waiting periods under the 
HSR Act and Foreign Competition Laws shall have expired or been terminated.

          (e)    STOCK EXCHANGE LISTING.  The shares of Acquiror Common Stock 
to be issued pursuant to the Merger shall have been approved for listing, 
subject to official notice of issuance, on the New York Stock Exchange.

          (f)    POOLING OF INTERESTS.  Acquiror shall have been advised in 
writing by Ernst & Young LLP as of the date upon which the Effective Time is 
to occur, in a form and in substance reasonably acceptable to Acquiror and 
the Company, that the transactions

                                      43
<PAGE>

contemplated by this Agreement, if consummated, can properly be accounted for 
as a "pooling of interests" business combination in accordance with GAAP and 
the criteria of Accounting Principles Board Opinion No. 16 and the 
Regulations of the SEC.  It is understood and agreed that (i) the obligations 
of the Company to effect the Merger shall not be subject to the condition set 
forth in this Section 8.1(f) to the extent that the Company shall have 
breached Section 4.21(a) or Section 7.6(e)(ii) hereof, but only if but for 
such breach the condition set forth in this Section 8.1(f) could have been 
satisfied (and provided that (A) if such breach is curable the Company shall

Company contained in this Agreement shall be true and correct as of the date 
hereof and at and as of the Closing Date as if made at and as of such time, 
except that, to the extent such representations and warranties address 
matters only as of a particular date, such representations and warranties 
shall, to such extent, be true and correct at and as of such particular date 
as if made at and as of such particular date; PROVIDED that if any of such 
representations and warranties shall not be true and correct as aforesaid, 
then the condition contained in this Section 8.2(a)(i) (but not the condition 
contained in Section 8.2(a)(ii)) shall nevertheless be deemed satisfied if 
the


                                      44
<PAGE>

cumulative effect of all inaccuracies of such representations and breaches of 
such warranties shall not be or have a Material Adverse Effect on the 
Company.  The Acquiror Companies shall have received a certificate of an 
executive officer of the Company, dated the date of the Effective Time, to 
such effect.

                 (ii)    The representations and warranties of the Company

such particular date; provided that if any of such representations and 
warranties shall not be true and correct as aforesaid, then the condition 
contained in this Section 8.2(a)(ii) shall nevertheless be deemed satisfied 
if the cumulative effect of all inaccuracies of such representations and 
breaches of such warranties shall not be or have a Material Adverse Effect on 
any Business Segment.

          (b)    AGREEMENTS AND COVENANTS.  The Company shall have performed 
or complied in all material respects with all agreements and covenants 
required by this Agreement to be performed or complied with by it at or prior 
to the Closing.  The Acquiror Companies shall have received a certificate of 
an executive officer of the Company, dated the Closing Date, to such effect.

          (c)    THIRD PARTY CONSENTS.  All Change of Control Consents of 
third parties required in order for a Change of Control Effect not to occur 
under any contract, note, bond, mortgage, indenture, license, agreement or 
other instrument to which the Company or any of its Subsidiaries is a party 
or by which it is bound and which is material to any Business Segment shall 
have been obtained, except where the failure to obtain such Change of Control 
Consents, either individually or in the aggregate, shall not have or be a 
Material Adverse Effect on the Company.

its tax counsel, Skadden, Arps, Slate, Meagher & Flom LLP, dated as of the 
Closing Date, to the effect that the Merger will qualify as a reorganization 
within the meaning of Section 368(a) of the Code; provided, however, that if 
such firm does not render such opinion, this condition shall nonetheless be 
deemed satisfied if such opinion, dated as of the Closing Date, is rendered

conditioned on the receipt by such tax counsel rendering such opinion of 
representation letters from each of Acquiror, Newco and the Company, in each 
case, in form and substance reasonably satisfactory to such tax counsel.  The 
specific provisions of each such representation letter shall be in form and 
substance reasonably satisfactory to such tax counsel rendering such opinion, 
and each such representation letter shall be dated on or before the date of 
such opinion and shall not have been withdrawn or modified in any material 
respect.

Company as being an Affiliate of the Company shall have delivered to Acquiror 
an executed Affiliate Agreement, in the form attached hereto as ANNEX C, 
which shall be in full force and effect.

          (f)    RIGHTS PLAN.  The provisions of the Company Rights Agreement 
and the Rights shall not apply to Acquiror or any of its Affiliates, 
individually or taken together, as a result of this Agreement, the Option 
Agreement, the Voting Agreement or the transactions contemplated hereby or 
thereby, or to the Merger, and all Company Rights issued thereunder shall, 
immediately prior to the Effective Time, be canceled, void and of no further 
force or effect.

obligations of the Company to effect the Merger and the other transactions 
contemplated hereby shall be subject to the satisfaction at or prior to the 
Effective Time of the following additional conditions, any or all of which 
may be waived by the Company, in whole or in part, to the extent permitted by

representations and warranties address matters only as of a particular date, 
such representations and warranties shall, to such extent, be true and 
correct as of the date hereof and at and as of such particular date as if 
made at and as of such particular date; PROVIDED that if any of such 
representations and warranties shall not be true and correct as aforesaid, 
then this condition shall nevertheless be deemed satisfied if the cumulative

warranties shall not be or have a Material Adverse Effect on Acquiror. The 
Company shall have received a certificate of an executive officer of each of 
the Acquiror Companies, dated the date of the Effective Time, to such effect.

its tax counsel, Wilson Sonsini Goodrich & Rosati, Professional Corporation, 
dated as of the Closing Date, to the effect that the Merger will qualify as a 
reorganization within the meaning of Section 368(a) of the Code; provided, 
however, that if such firm does not render such opinion, this condition shall 
nonetheless be deemed satisfied if such opinion, dated as of the Closing 
Date, is rendered to the Company by Skadden, Arps, Slate, Meagher & Flom LLP, 
tax counsel to Acquiror.  The issuance of such opinion shall be conditioned 
on the receipt by such tax

                                      46
<PAGE>

counsel rendering such opinion of representation letters from each of

such representation letter shall be in form and substance reasonably 
satisfactory to such tax counsel rendering such opinion, and each such 
representation letter shall be dated on or before the date of such opinion

          (b)    by Acquiror, upon a material breach of any covenant or 
agreement on the part of the Company set forth in this Agreement, or if any

<PAGE>

          (e)    by either Acquiror or the Company, if the Merger shall not 
have been consummated before June 30, 1999 (the "Termination Date"); 
PROVIDED, HOWEVER, that the right to terminate this Agreement under this 
Section 9.1(e) shall not be available to any party whose failure to fulfill 
any obligation under this Agreement has been a cause of, or resulted in, the 
failure of the Effective Time to occur on or before the Termination Date;

          (f)    by either Acquiror or the Company, if this Agreement shall 
fail to receive the requisite vote for approval and adoption by the

this Section 9.1 will remain operative and in full force and effect 
regardless of any investigation made by or on behalf of any party hereto, any 
Person controlling any such party or any of their respective officers, 
directors, representatives or agents, whether prior to or after the execution 
of this Agreement.

terms, of any representation, warranty, covenant or agreement contained in 
this Agreement.

hereto by action taken by or on behalf of their respective Boards of 
Directors at any time prior to the Effective Time; PROVIDED, HOWEVER, that, 
after approval of the Merger by the stockholders of the Company, no amendment 
may be made which would reduce the amount or change the type of consideration

this Agreement upon consummation of the Merger.  This Agreement may not be 
amended except by an instrument in writing signed by the parties hereto.

writing signed by the party or parties to be bound thereby.  For purposes of 
this Section 9.4, Acquiror Companies will be deemed to be one party.

     Section 9.5 EXPENSES.  Except as set forth in Section 9.2, all expenses 
incurred by the parties hereto will be borne solely and entirely by the party 
which has incurred such expenses; PROVIDED, HOWEVER, that the Company and

preclude other or further exercise thereof or of any other right.  All rights 
and remedies existing under this Agreement are cumulative to, and not 
exclusive to, and not exclusive of, any rights or remedies otherwise 
available.

and a newly-formed wholly owned direct subsidiary of Acquiror ("Newco"), have 
contemporaneously with the execution of this Voting Agreement, entered into 
an Agreement and Plan of Merger dated as of November 23, 1998 (the "Merger

respect to such shares of Company Common Stock;

     NOW, THEREFORE, in consideration of the foregoing and the mutual

                         written consent of Acquiror (provided nothing 
                         contained herein will be deemed to restrict the 
                         exercise of Options), unless the Person to whom Shares
                         or Options have been sold, assigned, pledged, 
                         hypothecated, transferred, exchanged or disposed 
                         agrees to be bound by this Voting Agreement as if a 
                         party hereto.

                 (b)     The Stockholder hereby agrees and consents to the entry
                         of stop transfer instructions by the Company against

Stockholder is competent to execute and deliver this Voting Agreement, to 
perform its obligations hereunder and to consummate the transactions 
contemplated hereby. This Voting Agreement has been duly and validly executed

execution and delivery by Acquiror, constitutes a legal, valid and binding 
obligation of such Stockholder, enforceable against such Stockholder in 
accordance with its terms.

          Section 3.2    NO CONFLICT.  The execution and delivery of this 
Voting Agreement by such Stockholder does not, and the performance of this

amendment, acceleration or cancellation of, or result in the creation of a 
lien or encumbrance, on any of the Shares or Options pursuant to, any note, 
bond, mortgage, indenture, contract, agreement, lease, license, permit, 
franchise or other instrument or obligation to which such Stockholder is a 
party or by which such Stockholder or the Shares or Options are bound or 
affected.

          Section 3.3    TITLE TO THE SHARES.  The Shares and Options held by 
such Stockholder are owned free and clear of all security interests, liens, 
claims, pledges, options, rights of first refusal, agreements, limitations on

nature whatsoever, and such Stockholder has not appointed or granted any 
proxy, which appointment or grant remains effective, with respect to the

                                      ARTICLE IV

                                    Miscellaneous

          Section 4.1    NO SOLICITATION.  From the date hereof until the 
Effective Time or, if earlier, the termination of the Merger Agreement, the 
Stockholder shall not (whether directly or indirectly through advisors, 
agents or other intermediaries) (a) solicit, initiate or encourage any 
Acquisition Proposal or (b) engage in discussions or negotiations with, or 
disclose any non-public information relating to the Company or its 
Subsidiaries to any Person that has made an Acquisition Proposal or has 
advised the Stockholder, or to his Knowledge, any other Stockholder or the 
Company, that such Person is interested in making an Acquisition Proposal.

          Section 4.2    TERMINATION.  This Agreement shall terminate upon 
the earliest to occur of (a) the termination of the Merger Agreement in 
accordance with its terms or (b) the Effective Time.  Upon such termination, 
no party shall have any further obligations or liabilities hereunder, 
provided that no such termination shall relieve any party from liability for 
any breach of this Voting Agreement prior to such termination.

          Section 4.3    ENFORCEMENT OF AGREEMENT.  The parties hereto agree 
that irreparable damage would occur in the event that any of the provisions 
of this Voting Agreement were not performed in accordance with its specified 
terms or were otherwise breached.  It is accordingly agreed that the parties 
shall be entitled to an injunction or injunctions to prevent breaches of this 
Voting Agreement and to specific performance of the terms and provisions 
hereof in addition to any other remedy to which they are entitled at law or 
in equity.

          Section 4.4    SUCCESSORS AND AFFILIATES.  This Voting Agreement 
shall inure to the benefit of and shall be binding upon the parties hereto 
and their

                                       5
<PAGE>

respective heirs, legal representatives and permitted assigns.  If any 
Stockholder shall at any time hereafter acquire ownership of, or voting power 
with respect to, any additional Shares in any manner, whether by the exercise 
of any Options or any securities or rights convertible into or exchangeable 
for shares of Company Common Stock, by operation of law or otherwise, such 
Shares shall be held subject to all of the terms and provisions of this 
Voting Agreement.  Without limiting the foregoing, each Stockholder 
specifically agrees that the obligations of such Stockholder hereunder shall 
not be terminated by operation of law, whether by death or incapacity of the 
Stockholder or otherwise.

          Section 4.5    ENTIRE AGREEMENT.  This Voting Agreement together 
with the Affiliates Agreements, in the form attached as Annex C to the Merger 
Agreement, if and to the extent entered into by each of the Stockholders and 
Acquiror constitutes the entire agreement among Acquiror and the Stockholders 
with respect to the subject matter hereof and supersedes all prior agreements 
and understandings, both written and oral, among Acquiror and the 
Stockholders with respect to the subject matter hereof.

          Section 4.6    CAPTIONS AND COUNTERPARTS.  The captions in this 
Voting Agreement are for convenience only and shall not be considered a part 
of or affect the construction or interpretation of any provision of this 
Voting Agreement.  This Voting Agreement may be executed in several 
counterparts, each of which shall constitute one and the same instrument.

          Section 4.7    AMENDMENT.  This Voting Agreement may not be amended 
except by an instrument in writing signed by the parties hereto.

          Section 4.8    WAIVERS.  Except as provided in this Voting 
Agreement, no action taken pursuant to this Voting Agreement, including 
without limitation any investigation by or on behalf of any party, shall be 
deemed to constitute a waiver by the party taking such action of compliance 
with any representations, warranties, covenants or agreements contained in 
this Voting Agreement.  The waiver by any party hereto of a breach of any 
provision hereunder shall not operate or be construed as a wavier of any 
prior or subsequent breach of the same or any other provision hereunder.

          Section 4.9    SEVERABILITY.  If any term or other provision of 
this Voting Agreement is invalid, illegal or incapable of being enforced by 
any rule of law, or public policy, all other conditions and provisions of 
this Voting Agreement 

                                       6
<PAGE>

shall nevertheless remain in full force and effect.  Upon such determination 
that any term or other provision is invalid, illegal or incapable of being 
enforced, the parties hereto shall negotiate in good faith to modify this 
Voting Agreement so as to effect the original intent of the parties as 
closely as possible to the fullest extent permitted by applicable law in a 
mutually acceptable manner in order that the terms of this Voting Agreement 
remain as originally contemplated to the fullest extent possible.
