ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

         (a) On March 17, 1997, the Registrant acquired Internet Middleware
Corporation ("IMC"), a California corporation, by statutory merger (the
"Merger"). The Merger was accomplished pursuant to the Agreement and Plan of
Reorganization, dated as of March 17, 1997, among the Registrant and IMC, and a
related Agreement of Merger (collectively, the "IMC Merger Agreements"). The
Merger of IMC with and into the Registrant occurred following the approval of
the IMC Merger Agreements by the shareholders of IMC by written consent which
was received on March 17, 1997 and by satisfaction of certain other closing
conditions. As a result of the Merger, each outstanding share of IMC Common
Stock was converted into 0.0345267 of a share of the Registrant's Common Stock.
Each outstanding option to purchase shares of IMC Common Stock was assumed by
the Registrant and converted into an option to purchase 0.0345267 of a share of
the Registrant's Common Stock.

         A total of approximately 187,023 shares of the Registrant's Common
Stock and options to purchase shares of the Registrant's Common Stock were
issued to IMC shareholders and optionholders in exchange for the acquisition by
the Registrant of all outstanding IMC Common Stock and all unexpired and
unexercised options to acquire IMC Common Stock.  Pursuant to the Merger,
certain key employees of IMC who will continue as employees of the Registrant
were granted options to purchase shares of the Registrant's Common Stock at a
discount to the market price of the Registrant's Common Stock immediately
preceding the Merger. The securities issued to IMC shareholders and
optionholders were issued pursuant to the exemption from registration provided
by Section 4(2) of the Securities Act of 1933, as amended (the "Securities
Act").  Under terms of the Merger, the Registrant will register the shares and
options issued to IMC shareholders and optionholders with the Securities and
Exchange Commission.

         The Merger is intended to be a tax-free reorganization under the
Internal Revenue Code of 1986, as amended, and will be accounted for as a
purchase.  A copy of the press release announcing the consummation of the
Merger is attached hereto as Exhibit 99.1.

         (b) IMC was founded in 1996 to develop and commercialize
Internet/Intranet proxy caching software.  The Registrant intends to continue
such business and to incorporate the IMC software into its existing products.

                      AGREEMENT AND PLAN OF REORGANIZATION


                 This AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is
made and entered into as of March 17, 1997, by and between Network Appliance,
Inc., a California corporation ("Acquiror") and Internet Middleware
Corporation, a California corporation ("Target").

                                    RECITALS

         A.      The Boards of Directors of Target and Acquiror believe it is
in the best interests of their respective companies and the shareholders of
their respective companies that Target and Acquiror combine into a single
company through the statutory merger of Target with and into Acquiror (the
"Merger") and, in furtherance thereof, have approved the Merger.

         B.      Pursuant to the Merger, among other things, all of the
outstanding shares of Target common stock ("Target Capital Stock") shall be
converted into shares of Acquiror Common Stock ("Acquiror Common Stock"), at
the rate set forth herein.

         C.      Target and Acquiror desire to make certain representations and
warranties and other agreements in connection with the Merger.

         D.      The parties intend, by executing this Agreement, to adopt a
plan of reorganization within the meaning of Section 368 of the Internal
Revenue Code of 1986, as amended (the "Code"), and to cause the Merger to
qualify as a reorganization under the provisions of Section 368(a)(1)(A) of the
Code.

         NOW, THEREFORE, in consideration of the covenants and representations
set forth herein, and for other good and valuable consideration, the parties
agree as follows:

                                   ARTICLE I

                                   THE MERGER

                 1.1      The Merger.  At the Effective Time (as defined in
Section 1.2) and subject to and upon the terms and conditions of this
Agreement, the Agreement of Merger attached hereto as Exhibit A (the "Agreement
of Merger") and the applicable provisions of the California Corporations Code
("California Law"), Target shall be merged with and into Acquiror, the separate
corporate existence of Target shall cease and Acquiror shall continue as the
surviving corporation.  Acquiror, as the surviving corporation after the
Merger, is hereinafter sometimes referred to as the "Surviving Corporation."





                                       1.
<PAGE>   7
                 1.2      Closing; Effective Time.  The closing of the
transactions contemplated hereby (the "Closing") shall take place as soon as
practicable after the satisfaction or waiver of each of the conditions set
forth in Article VI hereof or at such other time as the parties hereto agree
(the "Closing Date").  The Closing shall take place at a location to be
mutually agreed upon by the parties.  In connection with the Closing, the
parties hereto shall cause the Merger to be consummated by filing the Agreement
of Merger with the Secretary of State of the State of California in accordance
with the relevant provisions of California Law (the time of such filing being
the "Effective Time").

                 1.3      Effect of the Merger.  At the Effective Time, the
effect of the Merger shall be as provided in this Agreement, the Agreement of
Merger and the applicable provisions of California Law.  Without limiting the
generality of the foregoing, and subject thereto, at the Effective Time, all
the property, rights, privileges, powers and franchises of Target shall vest in
the Surviving Corporation, and all debts, liabilities and duties of Target
shall become the debts, liabilities and duties of the Surviving Corporation.

                 1.4      Articles of Incorporation; Bylaws.

                          (a)     At the Effective Time, the Restated Articles
of Incorporation (the "Articles of Incorporation") of Acquiror, as in effect
immediately prior to the Effective Time, shall be the Articles of Incorporation
of the Surviving Corporation until thereafter amended as provided by California
Law and such Articles of Incorporation.

                          (b)     The Bylaws of Acquiror, as in effect
immediately prior to the Effective Time, shall be the Bylaws of the Surviving
Corporation until thereafter amended.

                 1.5      Effect on Capital Stock.  By virtue of the Merger and
without any action on the part of Acquiror or Target or the holders of any of
the following securities:

                          (a)     Conversion of Target Common Stock.  At the
Effective Time, each share of Target Common Stock issued and outstanding
immediately prior to the Effective Time (other than any shares of Target Common
Stock to be canceled pursuant to Section 1.5(b)) will be canceled and
extinguished and be converted automatically into the right to receive that
number of shares of Acquiror Common Stock obtained by dividing $1.3569 by the
average of the closing prices of Acquiror's Common Stock as quoted on the
Nasdaq National Market for the ten trading days immediately preceding (and
including) the second trading day prior to the Closing (the "Closing Price"),
provided that, if the Closing Price is less than thirty-six dollars ($36.00)
per share, then the Closing Price shall be thirty-six dollars ($36.00) per
share, and, if the Closing Price is more than fifty-four dollars ($54.00) per
share, then the Closing Price shall be fifty-four dollars per share (the
"Exchange Ratio").





                                       2.
<PAGE>   8
                          (b)     Target Stock Option Plan.  At the Effective
Time, the Target's 1996 Long Term Equity Incentive Plan (the "Target Stock
Option Plan") and all options to purchase Target Common Stock then outstanding
under the Target Stock Option Plan (each a "Target Right") shall be assumed by
Acquiror in accordance with Section 5.12.

                          (c)     Adjustments to Exchange Ratio.  The Exchange
Ratio shall be adjusted to reflect fully the effect of any stock split, reverse
stock split, stock dividend (including any dividend or distribution of
securities convertible into Acquiror Common Stock or Target Capital Stock),
reorganization, recapitalization or other like change with respect to Acquiror
Common Stock or Target Capital Stock.

                          (d)     Fractional Shares.  No fraction of a share of
Acquiror Common Stock will be issued, but in lieu thereof each holder of shares
of Target Capital Stock who would otherwise be entitled to a fraction of a
share of Acquiror Common Stock (after aggregating all fractional shares of
Acquiror Common Stock to be received by such holder) shall receive from
Acquiror an amount of cash (rounded to the nearest whole cent) equal to the
product of (i) such fraction, multiplied by (ii) the Closing Price.

                          (e)     Dissenters' Rights.  Any dissenting shares as
defined by Section 1300 of California Law ("Dissenting Shares") shall not be
converted into Acquiror Common Stock but shall instead be converted into the
right to receive such consideration as may be determined to be due with respect
to such Dissenting Shares pursuant to California Law.  Target agrees that,
except with the prior written consent of Acquiror, or as required under
California Law, it will not voluntarily make any payment with respect to, or
settle or offer to settle, any such purchase demand.  Each holder of Dissenting
Shares ("Dissenting Shareholder") who, pursuant to the provisions of California
Law, becomes entitled to payment for shares of Target Capital Stock shall
receive payment therefor (but only after the value therefor shall have been
agreed upon or finally determined pursuant to such provisions).  If, after the
Effective Time, any Dissenting Shares shall lose their status as Dissenting
Shares, Acquiror shall issue and deliver, upon surrender by such shareholder of
certificate or certificates representing shares of Target Capital Stock, the
number of shares of Acquiror Common Stock to which such shareholder would
otherwise be entitled under this Section 1.5 and the Agreement of Merger.

                 1.6      Surrender of Certificates.

                          (a)     Exchange Agent.  The Harris Trust Company of
California shall act as exchange agent (the "Exchange Agent") in the Merger.

                          (b)     Acquiror to Provide Common Stock and Cash.
Promptly after the Effective Time, Acquiror shall make available to the
Exchange Agent for exchange in accordance with this Article I, through such
reasonable procedures as Acquiror may adopt, (i)





                                       3.
<PAGE>   9
the shares of Acquiror Common Stock issuable pursuant to Section 1.5(a) in
exchange for shares of Target Capital Stock outstanding immediately prior to
the Effective Time and (ii) cash in an amount sufficient to permit payment of
cash in lieu of fractional shares pursuant to Section 1.5(d).

                          (c)     Exchange Procedures.  Promptly after the
Effective Time, the Surviving Corporation shall cause to be mailed to each
holder of record of a certificate or certificates (the "Certificates") which
immediately prior to the Effective Time represented outstanding shares of
Target Capital Stock, whose shares were converted into the right to receive
shares of Acquiror Common Stock (and cash in lieu of fractional shares)
pursuant to Section 1.5, (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates
shall pass, only upon receipt of the Certificates by the Exchange Agent, and
shall be in such form and have such other provisions as Acquiror may reasonably
specify) and (ii) instructions for use in effecting the surrender of the
Certificates in exchange for certificates representing shares of Acquiror
Common Stock (and cash in lieu of fractional shares).  Upon surrender of a
Certificate for cancellation to the Exchange Agent or to such other agent or
agents as may be appointed by Acquiror, together with such letter of
transmittal, duly completed and validly executed in accordance with the
instructions thereto, the holder of such Certificate shall be entitled to
receive in exchange therefor a certificate representing the number of whole
shares of Acquiror Common Stock and payment in lieu of fractional shares which
such holder has the right to receive pursuant to Section 1.5, and the
Certificate so surrendered shall forthwith be canceled.  Until so surrendered,
each outstanding Certificate that, prior to the Effective Time, represented
shares of Target Capital Stock will be deemed from and after the Effective
Time, for all corporate purposes, other than the payment of dividends, to
evidence the ownership of the number of full shares of Acquiror Common Stock
into which such shares of Target Capital Stock shall have been so converted and
the right to receive an amount in cash in lieu of the issuance of any
fractional shares in accordance with Section 1.5.

                          (d)     Distributions With Respect to Unexchanged
Shares.  No dividends or other distributions with respect to Acquiror Common
Stock with a record date after the Effective Time will be paid to the holder of
any unsurrendered Certificate with respect to the shares of Acquiror Common
Stock represented thereby until the holder of record of such Certificate shall
surrender such Certificate.  Subject to applicable law, following surrender of
any such Certificate, there shall be paid to the record holder of the
certificates representing whole shares of Acquiror Common Stock issued in
exchange therefor, without interest, at the time of such surrender, the amount
of any such dividends or other distributions with a record date after the
Effective Time theretofore payable (but for the provisions of this Section
1.6(d)) with respect to such shares of Acquiror Common Stock.

                          (e)     Transfers of Ownership.  If any certificate
for shares of Acquiror Common Stock is to be issued in a name other than that
in which the Certificate surrendered in





                                       4.
<PAGE>   10
exchange therefor is registered, it will be a condition of the issuance thereof
that the Certificate so surrendered will be properly endorsed and otherwise in
proper form for transfer and that the person requesting such exchange will have
paid to Acquiror or any agent designated by it any transfer or other taxes
required by reason of the issuance of a certificate for shares of Acquiror
Common Stock in any name other than that of the registered holder of the
Certificate surrendered, or established to the satisfaction of Acquiror or any
agent designated by it that such tax has been paid or is not payable.

                          (f)     No Liability.  Notwithstanding anything to
the contrary in this Section 1.6, none of the Exchange Agent, the Surviving
Corporation or any party hereto shall be liable to any person for any amount
properly paid to a public official pursuant to any applicable abandoned
property, escheat or similar law.

                          (g)     Dissenting Shares.  The provisions of this
Section 1.6 shall also apply to Dissenting Shares that lose their status as
such, except that the obligations of Acquiror under this Section 1.6 shall
commence on the date of loss of such status and the holder of such shares shall
be entitled to receive in exchange for such shares the number of shares of
Acquiror Common Stock to which such holder is entitled pursuant to Section 1.5
hereof.

                 1.7      No Further Ownership Rights in Target Capital Stock.
All shares of Acquiror Common Stock issued upon the surrender for exchange of
shares of Target Capital Stock in accordance with the terms hereof (including
any cash paid in lieu of fractional shares) shall be deemed to have been issued
in full satisfaction of all rights pertaining to such shares of Target Capital
Stock and there shall be no further registration of transfers on the records of
the Surviving Corporation of shares of Target Capital Stock which were
outstanding immediately prior to the Effective Time.  If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be canceled and exchanged as provided in this Article I.

                 1.8      Lost, Stolen or Destroyed Certificates.  In the event
any Certificates shall have been lost, stolen or destroyed, the Exchange Agent
shall issue in exchange for such lost, stolen or destroyed Certificates, upon
the making of an affidavit of that fact by the holder thereof, such shares of
Acquiror Common Stock (and cash in lieu of fractional shares) as may be
required pursuant to Section 1.5; provided, however, that Acquiror may, in its
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed Certificates to deliver a bond in such
sum as it may reasonably direct as indemnity against any claim that may be made
against Acquiror, the Surviving Corporation or the Exchange Agent with respect
to the Certificates alleged to have been lost, stolen or destroyed.

                 1.9      Tax Consequences.  It is intended by the parties
hereto that the Merger shall constitute a reorganization within the meaning of
Section 368 of the Code.

<PAGE>   11
                 1.10     Exemption from Registration.  The shares of Acquiror
Common Stock to be issued in connection with the Merger will be issued in a
transaction exempt from registration under the Securities Act of 1933, as
amended (the "Securities Act"), by reason of Section 4(2) thereof.  Acquiror
shall use commercially reasonable efforts to prepare and file, as promptly as
practicable, and, in any event, within 45 days following the Closing, a
registration statement with the Securities and Exchange Commission covering the
resale of such shares of Acquiror Common Stock issued in connection with the
Merger and Acquiror shall use commercially reasonable efforts to cause such
registration statement to become effective as promptly as practicable after
filing and to keep such registration statement effective until two (2) years
after the Effective Time.  Any such registration shall be subject to the normal
terms and conditions used in connection with resale prospectuses.  Pursuant to
the filing of a registration statement pursuant to this Article I:

                          (a)     Acquiror will indemnify each holder of shares
of Acquiror Common Stock issued in connection with the Merger (a "Holder"),
each of Target's officers, directors and partners and such Target's legal
counsel and independent accountants, and each person controlling such Holder
within the meaning of Section 15 of the Securities Act, with respect to which
registration, qualification or compliance has been effected pursuant to this
Agreement, and each underwriter, if any, and each person who controls any
underwriter within the meaning of Section 15 of the Securities Act, against all
expenses, claims, losses, damages and liabilities (or actions in respect
thereof), including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any
registration statement, prospectus, offering circular or other document, or any
amendment or supplement thereto, incident to any such registration,
qualification or compliance, or based on any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances in which they are
made, not misleading, or any violation by Acquiror of any rule or regulation
promulgated under the Securities Act, or state securities laws, or common law,
applicable to Acquiror in connection with any such registration, qualification
or compliance, and will reimburse each such Holder, each of Target's officers,
directors and partners and such Target's legal counsel and independent
accountants, and each person controlling such Holder, each such underwriter and
each person who controls any such underwriter, for any legal and any other
expenses reasonably incurred in connection with investigating, preparing or
defending any such claim, loss, damage, liability or action as such expenses
are incurred, provided that Acquiror will not be liable in any such case to the
extent that any such claim, loss, damage, liability or expense arises out of or
is based in any untrue statement or omission or alleged untrue statement or
omission, made in reliance upon and in conformity with written information
furnished to Acquiror in an instrument duly executed by such Holder or
underwriter and stated to be specifically for use therein.

                          (b)     Each Holder will, if securities held by such
Holder are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify Acquiror, each of
Acquiror's directors and officers and its legal counsel and independent
accountants, each underwriter, if any, of Acquiror's securities covered by such
a registration statement, each person who controls Acquiror or such underwriter
within the meaning of Section 15 of the Securities Act, and each other such
Holder, each of Target's officers and directors and each person controlling
such other Holder within the meaning of Section 15 of the Securities Act,
against all claims, losses, damages and liabilities (or actions in respect
thereof) arising out of or based on any untrue statement (or alleged untrue
statement) or a material fact contained in any such registration statement,
prospectus, offering circular or other document, or any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse
Acquiror, such other Holders, such directors, officers, legal counsel,
independent accountants, underwriters or control persons for any legal or any
other expenses reasonably incurred in connection with investigating or
defending any such claim, loss, damage, liability or action as such expenses
are incurred, in each case to the extent, but only to the extent, that such
untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to Acquiror by an instrument duly executed by such Holder and stated
to be specifically for use therein; provided, however, that the obligations of
such Holders hereunder shall be limited to an amount equal to the proceeds
received by each such Holder from the sale of the Registrable Securities sold
as contemplated herein.

                          (c)     Each party entitled to indemnification under
this Section 1.10 (the "Indemnified Party") shall give notice to the party
required to provide indemnification (the "Indemnifying Party") promptly after
such Indemnified Party has written notice of any claim as to which indemnity
may be sought, and shall permit the Indemnifying Party to assume the defense of
any such claim or any litigation resulting therefrom, provided that counsel for
the Indemnifying Party, who shall conduct the defense of such claim or
litigation, shall be approved by the Indemnified Party (whose approval shall
not be unreasonably withheld), and the Indemnified Party may participate in
such defense at such party's expense, and provided further that the failure of
any Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Agreement, except to the
extent, but only to the extent, that the Indemnifying Party's ability to defend
against such claim or litigation is impaired as a result of such failure to
give notice.  No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent
to entry of any judgment or enter any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation.

                          (d)     The indemnification obligations of Acquiror
and each Holder under this Section 1.10 shall survive the completion of any
offering of stock in a registration statement under this Section 1.10.  It is
intended that each Holder shall be a third party beneficiary of the Company's
obligations set forth in this Section 1.10.

                 1.11     Taking of Necessary Action; Further Action.  If, at
any time after the Effective Time, any further action is necessary or desirable
to carry out the purposes of this Agreement and to vest the Surviving
Corporation with full right, title and possession to all assets, property,
rights, privileges, powers and franchises of Target, the officers and directors
of Acquiror and Target are fully authorized in the name of their respective
corporations or otherwise to take, and will take, all such lawful and necessary
action, so long as such action is not inconsistent with this Agreement.

                                   ARTICLE II

                    REPRESENTATIONS AND WARRANTIES OF TARGET

                 In this Agreement, any reference to any event, change,
condition or effect being "material" with respect to Target or Acquiror means
any material event, change, condition or effect related to the condition
(financial or otherwise), properties, assets (including intangible assets),
liabilities, business, operations or results of operations of Target or
Acquiror, respectively.  In this Agreement, any reference to a "Material
Adverse Effect" with respect to Target or Acquiror means any event, change or
effect that is materially adverse to the condition (financial or otherwise),
properties, assets, liabilities, business, operations or results of operations
of Target or Acquiror, respectively.

                 In this Agreement, any reference to a party's "knowledge"
means such party's actual knowledge after due and diligent inquiry of officers,
directors and other employees of such party reasonably believed to have
knowledge of such matters.

                 Except as disclosed in a document of even date herewith and
delivered by Target to Acquiror prior to the execution and delivery of this
Agreement and specifically referring to the relevant section and subsection of
this Article II (the "Target Disclosure Schedule"), Target represents and
warrants to Acquiror as follows:

                 2.1      Organization, Standing and Power.  Target is a
corporation duly incorporated, validly existing and in good standing under the
laws of its jurisdiction of organization.  Target has the corporate power to
own its properties and to carry on its business as now being conducted and as
proposed to be conducted and is duly qualified to do business and is in good
standing in each jurisdiction in which the failure to be so qualified and in
good standing would have a Material Adverse Effect on Target.  Target has
delivered a true and correct copy of its Articles of Incorporation (the
"Articles of Incorporation") and its Bylaws,





                                       8.
<PAGE>   14
each as amended to date, to Acquiror.  Target is not in violation of any of the
provisions of its Articles of Incorporation or Bylaws or equivalent
organizational documents.  Target does not directly or indirectly own any
equity or similar interest in, or any interest convertible or exchangeable or
exercisable for, any equity or similar interest in, any corporation,
partnership, joint venture or other business association or entity.

                 2.2      Capital Structure.  The authorized capital stock of
Target consists of 25,000,000 shares of Common Stock, of which there were
issued and outstanding as of the close of business on March 14, 1997, 4,992,500
shares of Common Stock.  There are no other outstanding shares of capital stock
or voting securities and no outstanding commitments to issue any shares of
capital stock or voting securities after March 14, 1997 other than pursuant to
the exercise of options outstanding as of such date under the Target Stock
Option Plan.  All outstanding shares of Target Capital Stock are duly
authorized, validly issued, fully paid and non-assessable and are free of any
liens or encumbrances created by Target and, to Target's knowledge, free of any
other liens or encumbrances other than any liens or encumbrances created by or
imposed upon the holders thereof, and are not subject to preemptive rights or
rights of first refusal created by statute, the Articles of Incorporation or
Bylaws of Target or any agreement to which Target is a party or by which it is
bound.  As of the close of business on March 14, 1997, Target has reserved (i)
10,000,000 shares of Common Stock for issuance to employees, officers,
directors and consultants pursuant to the Target Stock Option Plan, of which no
shares have been issued pursuant to option exercises, 424,290 shares are
subject to outstanding, unexercised options, and no shares are subject to
outstanding stock purchase rights.  Since March 14, 1997, Target has not (i)
issued or granted additional options under the Target Stock Option Plan or (ii)
granted additional warrants or options to acquire Target Capital Stock.  Except
as set forth in Schedule 2.2 and except for (i) the rights created pursuant to
this Agreement, (ii) Target's right to repurchase restricted shares or shares
issued upon the exercise of stock options granted under the Target Stock Option
Plan and (iii) options referred to in this Section 2.2, there are no other
options, warrants, calls, rights, commitments or agreements of any character to
which Target is a party or by which it is bound obligating Target to issue,
deliver, sell, repurchase or redeem, or cause to be issued, delivered, sold,
repurchased or redeemed, any shares of capital stock of Target or obligating
Target to grant, extend, accelerate the vesting of, change the price of, or
otherwise amend or enter into any such option, warrant, call, right, commitment
or agreement.  Except as set forth in Schedule 2.2, there are no other
contracts, commitments or agreements relating to voting, purchase or sale of
Target's capital stock (i) between or among Target and any of its shareholders
and (ii) to Target's knowledge, between or among any of Target's shareholders,
except for the shareholders delivering Shareholder Agreement (as defined
below.)  The terms of the Target Stock Option Plan permit the assumption or
substitution of options or warrants, as applicable, to purchase Acquiror Common
Stock as provided in this Agreement, without the consent or approval of the
holders of such securities, the Target shareholders, or otherwise and without
any acceleration of the exercise schedule or vesting provisions in effect for
those options.  True and complete copies of all agreements and instruments
relating to or issued under the





                                       9.
<PAGE>   15
Target Stock Option Plan have been made available to Acquiror and such
agreements and instruments have not been amended, modified or supplemented, and
there are no agreements to amend, modify or supplement such agreements or
instruments in any case from the form made available to Acquiror.  All
outstanding Target Capital Stock was issued in compliance with all applicable
federal and state securities laws.

                 2.3      Authority.  Target has all requisite corporate power
and authority to enter into this Agreement and to consummate the transactions
contemplated hereby.  The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby have been duly authorized
by all necessary corporate action on the part of Target, subject only to the
approval of the Merger by Target's shareholders as contemplated by Section
6.1(a). This Agreement has been duly executed and delivered by Target and
constitutes the valid and binding obligation of Target enforceable against
Target in accordance with its terms, except that such enforceability may be
limited by bankruptcy, insolvency, moratorium or other similar laws affecting
or relating to creditors' rights generally, and is subject to general
principles of equity.  The execution and delivery of this Agreement by Target
does not, and the consummation of the transactions contemplated hereby will
not, conflict with, or result in any violation of, or default under (with or
without notice or lapse of time, or both), or give rise to a right of
termination, cancellation or acceleration of any obligation or loss of any
benefit under (i) any provision of the Articles of Incorporation or Bylaws of
Target, or (ii) any material mortgage, indenture, lease, contract or other
agreement or instrument, permit, concession, franchise, license, judgment,
order, decree, statute, law, ordinance, rule or regulation applicable to Target
or any of its properties or assets.  No consent, approval, order or
authorization of, or registration, declaration or filing with, any court,
administrative agency or commission or other governmental authority or
instrumentality ("Governmental Entity") is required by or with respect to
Target in connection with the execution and delivery of this Agreement or the
consummation of the transactions contemplated hereby, except for (i) the filing
of the Agreement of Merger; (ii) such consents, approvals, orders,
authorizations, registrations, declarations and filings as may be required
under applicable state securities laws and the securities laws of any foreign
country; and (iii) such other consents, authorizations, filings, approvals and
registrations which, if not obtained or made, would not have a Material Adverse
Effect on Target and would not prevent, or alter or delay any of the
transactions contemplated by this Agreement.

                 2.4      Financial Statements.  Target has delivered to
Acquiror its unaudited financial statements for the months ended January 31,
1997 (collectively, the "Financial Statements").  The Financial Statements are
complete and correct in all material respects.  The Financial Statements fairly
present the consolidated financial condition and operating results of Target at
the dates and during the periods indicated therein (subject, in the case of
unaudited statements, to normal, recurring year-end adjustments).





                                      10.
<PAGE>   16
                 2.5      Absence of Certain Changes.  Since January 31, 1997,
(the "Target Balance Sheet Date"), Target has conducted its business in the
ordinary course consistent with past practice and there has not occurred: (i)
any change, event or condition (whether or not covered by insurance) that has
resulted in, or is reasonably expected by Target to result in, a Material
Adverse Effect to Target; (ii) any acquisition, sale or transfer of any
material asset of Target other than in the ordinary course of business and
consistent with past practice; (iii) any change in accounting methods or
practices (including any change in depreciation or amortization policies or
rates) by Target or any revaluation by Target of any of its assets; (iv) any
declaration, setting aside, or payment of a dividend or other distribution with
respect to the shares of Target Capital Stock, or any direct or indirect
redemption, purchase or other acquisition by Target of any shares of Target
Capital Stock; (v) any material contract entered into by Target, other than in
the ordinary course of business and as provided to Acquiror, or any amendment
or termination of, or default under, any material contract to which Target is a
party or by which it is bound; (vi) any amendment or change to the Articles of
Incorporation or Bylaws of Target; (vii) any increase in or modification of the
compensation or benefits payable or to become payable by Target to any of its
directors or employees or (viii) any negotiation or agreement by Target to do
any of the things described in the preceding clauses (i) through (vii) (other
than negotiations with Acquiror and its representatives regarding the
transactions contemplated by this Agreement).

                 2.6      Absence of Undisclosed Liabilities.  Target has no
material obligations or liabilities of any nature (matured or unmatured, fixed
or contingent) other than (i) those set forth or adequately provided for in its
Balance Sheet as of January 31, 1997 (the "Target Balance Sheet"), (ii) those
incurred in the ordinary course of business and not required to be set forth in
the Target Balance Sheet under generally accepted accounting principles, (iii)
those incurred in the ordinary course of business since the Target Balance
Sheet Date and consistent with past practice, and (iv) those incurred in
connection with the execution of this Agreement.

                 2.7      Litigation.  To the knowledge of Target, there is no
private or governmental action, suit, proceeding, claim, arbitration or
investigation pending before any agency, court or tribunal, foreign or
domestic, or threatened against Target or any of its properties or any of its
officers or directors (in their capacities as such) that, individually or in
the aggregate, could reasonably be expected to have a Material Adverse Effect
on Target.  There is no judgment, decree or order against Target or, to the
knowledge of Target, any of its directors or officers (in their capacities as
such), that could prevent, enjoin, alter or delay any of the transactions
contemplated by this Agreement, or that could reasonably be expected to have a
Material Adverse Effect on Target.  To the knowledge of Target, all litigation
to which Target is a party (or threatened to become a party) is disclosed in
Schedule 2.7.

                 2.8      Restrictions on Business Activities.  There is no
agreement, judgment, injunction, order or decree binding upon Target which has
or could reasonably be expected to have the effect of prohibiting or impairing
any current or future business practice of Target,





                                      11.
<PAGE>   17
any acquisition of property by Target or the conduct of business by Target as
currently conducted or as proposed to be conducted by Target.

                 2.9      Governmental Authorization.  Target has obtained each
federal, state, county, local or foreign governmental consent, license, permit,
grant, or other authorization of a Governmental Entity (i) pursuant to which
Target currently operates or holds any interest in any of its properties or
(ii) that is required for the operation of Target's business or the holding of
any such interest ((i) and (ii) herein collectively called "Target
Authorizations"), and all of such Target Authorizations are in full force and
effect, except where the failure to obtain or have any such Target
Authorizations could not reasonably be expected to have a Material Adverse
Effect on Target.

                 2.10     Title to Property.  Target has good and marketable
title to all of its properties, interests in properties and assets, real and
personal, reflected in the Target Balance Sheet or acquired after the Target
Balance Sheet Date (except properties, interests in properties and assets sold
or otherwise disposed of since the Target Balance Sheet Date in the ordinary
course of business), or with respect to leased properties and assets, valid
leasehold interests in, free and clear of all mortgages, liens, pledges,
charges or encumbrances of any kind or character, except (i) the lien of
current taxes not yet due and payable, (ii) such imperfections of title, liens
and easements as do not and will not materially detract from or interfere with
the use of the properties subject thereto or affected thereby, or otherwise
materially impair business operations involving such properties and (iii) liens
securing debt which is reflected on the Target Balance Sheet.  The plants,
property and equipment of Target that are used in the operation of its business
are taken as a whole in all material respects in good operating condition and
repair.  All properties used in the operations of Target are reflected in the
Target Balance Sheet to the extent generally accepted accounting principles
require the same to be reflected.  Schedule 2.10 identifies each parcel of real
property owned or leased by Target.

                 2.11     Intellectual Property.

                          (a)     Except as set forth in Schedule 2.11, Target
owns, or is licensed or otherwise possesses legally enforceable rights to use
all patents, trademarks, trade names, service marks, copyrights, and any
applications therefor, maskworks, net lists, schematics, technology, know-how,
trade secrets, inventory, ideas, algorithms, processes, computer software
programs or applications (in both source code and object code form), and
tangible or intangible proprietary information or material ("Intellectual
Property") that are used or currently proposed to be used in the business of
Target as currently conducted or as currently proposed to be conducted by
Target, except to the extent that the failure to have such rights has not had
and would not reasonably be expected to have a Material Adverse Effect on
Target.





                                      12.
<PAGE>   18
                          (b)     Schedule 2.11 also lists (i) all patents and
patent applications and all registered and unregistered trademarks, trade names
and service marks, registered and unregistered copyrights, and maskworks,
included in the Intellectual Property, including the jurisdictions in which
each such Intellectual Property right has been issued or registered or in which
any application for such issuance and registration has been filed, (ii) all
licenses, sublicenses and other agreements to which Target is a party and
pursuant to which any person is authorized to use any Target Intellectual
Property, and (iii) all licenses, sublicenses and other agreements as to which
Target is a party and pursuant to which Target is authorized to use any third
party patents, trademarks or copyrights, including software ("Third Party
Intellectual Property Rights") which are incorporated in, are, or form a part
of any Target product.

                          (c)     To the knowledge of Target, there is no
unauthorized use, disclosure, infringement or misappropriation of any
Intellectual Property rights of Target, any trade secret of Target, or any
Intellectual Property right of any third party to the extent licensed by or
through Target, by any third party, including any employee or former employee
of Target.  Target has not entered into any agreement to indemnify any person
against any charge of infringement of any Intellectual Property, other than
indemnification provisions contained in sales invoices arising in the ordinary
course of business.

                          (d)     Target is not, nor will it be as a result of
the execution and delivery of this Agreement or the performance of its
obligations under this Agreement, in breach of any license, sublicense or other
agreement relating to the Intellectual Property or Third Party Intellectual
Property Rights, the breach of which would have a Material Adverse Effect on
Target.

                          (e)     All patents, registered trademarks, service
marks and copyrights held by Target are valid and subsisting.  Target (i) has
not to Target's knowledge been sued in any suit, action or proceeding which
involves a claim of infringement of any patents, trademarks, service marks,
copyrights or violation of any trade secret or other proprietary right of any
third party; and (ii) has not brought any action, suit or proceeding for
infringement of Intellectual Property or breach of any license or agreement
involving Intellectual Property against any third party.  The manufacturing,
marketing, licensing or sale of Target's products does not infringe any patent,
trademark, service mark, copyright, trade secret or other proprietary right of
any third party, where such infringement would have a Material Adverse Effect
on Target.

                          (f)     Target has secured valid written assignments
from all consultants and employees who contributed to the creation or
development of Target Intellectual Property of the rights to such contributions
that Target does not already own by operation of law, the absence of which
would have a Material Adverse Effect on Target.

<PAGE>   19
                          (g)     All use, disclosure or appropriation of
Intellectual Property not otherwise protected by patents, patent applications
or copyright ("Confidential Information"), owned by Target by or to a third
party has been pursuant to the terms of a written agreement between Target and
such third party.  All use, disclosure or appropriation of Confidential
Information not owned by Target has been pursuant to the terms of a written
agreement between Target and the owner of such Confidential Information, or is
otherwise lawful.

                 2.12     Environmental Matters.

                          (a)     The following terms shall be defined as

                 2.13     Taxes.  Target, and any consolidated, combined or
unitary group for Tax purposes of which Target is or has been a member have
timely filed all Tax Returns required to be filed by them and have paid all
Taxes shown thereon to be due.  The Financial Statements (i) fully accrue all

excess of the amount reflected on the Financial Statements with respect to such

provision has been made in the Financial Statements for all Taxes since that
date.  Target has withheld and paid to the applicable financial institution or
Tax Authority all amounts required to be withheld.  No notice of deficiency or
similar document of any Tax Authority has been received by Target, and there
are no liabilities for Taxes with respect to the issues that have been raised
(and are currently pending) by any Tax Authority that could, if determined
adversely to Target, materially and adversely affect the liability of Target
for Taxes.  Target has received no notification of any audit of any Tax Return
of Target being conducted pending or threatened by a Tax authority.  There is
(i) no material claim for Taxes that is a lien against the property of Target
other than liens for Taxes not yet due and payable, (ii) no extension or waiver
of the statute of limitations on the assessment of any Taxes granted by Target
and currently in effect, and (iii) except as set forth in Schedule 2.13, no
agreement, contract or arrangement to which Target is a party that may result
in the payment of any material amount that would not be deductible by reason of
Sections 280G or 404 of the Code.  Except as set forth in Schedule 2.13, Target
will not be required to include any material adjustment in Taxable income for
any Tax period (or portion thereof) pursuant to Section 481 or 263A of the Code
or any comparable provision under state or foreign Tax laws as a result of
transactions, events or accounting methods employed prior to the Merger.
Target is not a party to any tax-sharing or tax allocation agreement nor does
Target owe any amount under any such agreement.  For purposes of this
Agreement, "Tax" (and, with correlative meaning, "Taxes" and "Taxable") means
(i) any net income, alternative or add-on minimum tax, gross income, gross
receipts, sales, use, ad valorem, transfer, franchise, profits, license,





                                      15.

imposed by any Governmental Entity (a "Tax Authority") responsible for the
imposition of any such tax (domestic or foreign), (ii) any liability for the
payment of any amounts of the type described in (i) as a result of being a
member of an affiliated, consolidated, combined or unitary group for any
Taxable period and (iii) any liability for the payment of any amounts of the
type described in (i) or (ii) as a result of any express or implied obligation
to indemnify any other person.  As used herein, "Tax Return" shall mean any
return, statement, report or form (including, without limitation,) estimated
Tax returns and reports, withholding Tax returns and reports and information
reports and returns required to be filed with respect to Taxes.  Target is in
full compliance with all terms and conditions of any Tax exemptions or other
Tax-sharing agreement or order of a foreign government applicable to them and
the consummation of the Merger shall not have any adverse effect on the
continued validity and effectiveness of any such Tax exemptions or other
Tax-sharing agreement or order.  Target operates at least one historic business
line, or owns at least a significant portion of its historic business assets,
in each case within the meaning of Section 1.368-1(d) of the Treasury
Regulations.

                 2.14     Employee Benefit Plans.

                          (a)     Schedule 2.14 lists, with respect to Target
and any trade or business (whether or not incorporated) which is treated as a
single employer with Target (an "ERISA Affiliate") within the meaning of
Section 414(b), (c), (m) or (o) of the Code, (i) all material employee benefit
plans (as defined in Section 3(3) of the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), (ii) each loan to a non-officer employee in
excess of $10,000, loans to officers and directors and any stock option, stock
purchase, phantom stock, stock appreciation right, supplemental retirement,
severance, sabbatical, medical, dental, vision care, disability, employee
relocation, cafeteria benefit (Code section 125) or dependent care (Code
Section 129), life insurance or accident insurance plans, programs or
arrangements, (iii) all material bonus, pension, profit sharing, savings,
deferred compensation or incentive plans, programs or arrangements, (iv) other
material fringe or employee benefit plans, programs or arrangements that apply
to senior management of Target and that do not generally apply to all employees
and (v) any current or former employment or executive compensation or severance
agreements, written or otherwise, as to which unsatisfied obligations of Target
of greater than $10,000 remain for the benefit of, or relating to, any present
or former employee, consultant or director of Target (collectively, the "Target
Employee Plans").

                          (b)     Target has furnished to Acquiror a copy of
each of the Target Employee Plans and related plan documents (including trust
documents, insurance policies or contracts, employee booklets, summary plan
descriptions and other authorizing documents,





                                      16.

and, to the extent still in its possession, any material employee
communications relating thereto) and has, with respect to each Target Employee
Plan which is subject to ERISA reporting requirements, provided copies of the
Form 5500 reports filed for the last three plan years.  Any Target Employee
Plan intended to be qualified under Section 401(a) of the Code has either
obtained from the Internal Revenue Service a favorable determination letter as
to its qualified status under the Code, including all amendments to the Code
effected by the Tax Reform Act of 1986 and subsequent legislation, or has
applied to the Internal Revenue Service for such a determination letter prior
to the expiration of the requisite period under applicable Treasury Regulations
or Internal Revenue Service pronouncements in which to apply for such
determination letter and to make any amendments necessary to obtain a favorable
determination, or has been established under a standardized prototype plan for
which an Internal Revenue Service opinion letter has been obtained by the plan
sponsor and is valid as to the adopting employer.  Target has also furnished
Acquiror with the most recent Internal Revenue Service determination or opinion
letter issued with respect to each such Target Employee Plan, and nothing has
occurred since the issuance of each such letter which could reasonably be
expected to cause the loss of the tax-qualified status of any Target Employee
Plan subject to Code Section 401(a).

                          (c)     (i) None of the Target Employee Plans
promises or provides retiree medical or other retiree welfare benefits to any
person; (ii) there has been no "prohibited transaction," as such term is
defined in Section 406 of ERISA and Section 4975 of the Code, with respect to
any Target Employee Plan, which could reasonably be expected to have, in the
aggregate, a Material Adverse Effect; (iii) each Target Employee Plan has been
administered in accordance with its terms and in compliance with the
requirements prescribed by any and all statutes, rules and regulations
(including ERISA and the Code), except as would not have, in the aggregate, a
Material Adverse Effect, and Target and each ERISA Affiliate has performed all
material obligations required to be performed by them under, are not in any
material respect in default under or violation of, and have no knowledge of any
material default or violation by any other party to, any of the Target Employee
Plans; (iv) neither Target nor any ERISA Affiliate is subject to any liability
or penalty under Sections 4976 through 4980 of the Code or Title I of ERISA
with respect to any of the Target Employee Plans; (v) all material
contributions required to be made by Target or any ERISA Affiliate to any
Target Employee Plan have been made on or before their due dates and a
reasonable amount has been accrued for contributions to each Target Employee
Plan for the current plan years; (vi) with respect to each Target Employee
Plan, no "reportable event" within the meaning of Section 4043 of ERISA
(excluding any such event for which the thirty (30) day notice requirement has
been waived under the regulations to Section 4043 of ERISA) nor any event
described in Section 4062, 4063 or 4041 or ERISA has occurred; and (vii) no
Target Employee Plan is covered by, and neither Target nor any ERISA Affiliate
has incurred or expects to incur any liability under Title IV of ERISA or
Section 412 of the Code.  With respect to each Target Employee Plan subject to
ERISA as either an employee pension plan within the





                                      17.
<PAGE>   23
meaning of Section 3(2) of ERISA or an employee welfare benefit plan within the
meaning of Section 3(l) of ERISA, Target has prepared in good faith and timely
filed all requisite governmental reports (which were true and correct as of the
date filed) and has properly and timely filed and distributed or posted all
notices and reports to employees required to be filed, distributed or posted
with respect to each such Target Employee Plan.  No suit, administrative
proceeding, action or other litigation has been brought, or to the knowledge of
Target is threatened, against or with respect to any such Target Employee Plan,
including any audit or inquiry by the IRS or United States Department of Labor.
Neither Target nor any ERISA Affiliate is a party to, or has made any
contribution to or otherwise incurred any obligation under, any "multiemployer
plan" as defined in Section 3(37) of ERISA.

                          (d)     With respect to each Target Employee Plan,
Target has complied with (i) the applicable health care continuation and notice
provisions of the Consolidated Omnibus Budget Reconciliation Act of 1985
("COBRA") and the proposed regulations thereunder and (ii) the applicable
requirements of the Family Leave Act of 1993 and the regulations thereunder,
except to the extent that such failure to comply would not, in the aggregate,
have a Material Adverse Effect.

                          (e)     Except as set forth in Schedule 2.14(e)
either the execution and delivery of this Agreement nor the consummation of the
transactions contemplated hereby will (i) entitle any current or former
employee, director, or other service provider of Target or any ERISA Affiliate
to severance benefits or any other payment (including, without limitation,
unemployment compensation, golden parachute or bonus), except as expressly
provided in this Agreement, or (ii) accelerate the time of payment or vesting
of any such benefits, or increase the amount of compensation due any such
employee, director, or service provider, or (iii) increase any benefits
otherwise payable by Target.

                          (f)     There has been no amendment to, written
interpretation or announcement (whether or not written) by Target or any ERISA
Affiliate relating to, or change in participation or coverage under, any Target
Employee Plan which would materially increase the expense of maintaining such
Plan above the level of expense incurred with respect to that Plan for the most
recent fiscal year included in Target's financial statements.

                 2.15     Employee Matters.  To Target's knowledge, Target is
in compliance in all material respects with all currently applicable laws and
regulations respecting employment, discrimination in employment, terms and
conditions of employment, wages, hours and occupational safety and health and
employment practices, and are not engaged in any unfair labor practice.  There
are no pending claims against Target under any workers compensation plan or
policy or for long term disability.  Target has no material obligations under
COBRA with respect to any former employees or qualifying beneficiaries
thereunder.  To the knowledge of Target, there are no proceedings pending or
threatened, between Target and its employees, which proceedings have or could
reasonably be expected to have a Material





                                      18.
<PAGE>   24
Adverse Effect on Target.  Target is not a party to any collective bargaining
agreement or other labor unions contract nor does Target know of any activities
or proceedings of any labor union or organize any such employees.  In addition,
except as set forth in Schedule 2.15, Target has provided all employees with
all relocation benefits, stock options, bonuses and incentives, and all other
compensation that such employee has earned up through the date of this
Agreement or that such employee was otherwise promised in their employment
agreements with Target.

                 2.16     Interested Party Transactions.  Except as set forth
in Schedule 2.16, Target is not indebted to any director, officer, employee or
agent of Target (except for amounts due as normal salaries and bonuses and in
reimbursement of ordinary expenses), and no such person is indebted to Target.

                 2.17     Insurance.  Target has policies of insurance and
bonds of the type and in amounts described in Target's Disclosure Schedule.
There is no material claim pending under any of such policies or bonds as to
which coverage has been questioned, denied or disputed by the underwriters of
such policies or bonds.  All premiums due and payable under all such policies
and bonds have been paid and Target is otherwise in compliance with the terms
of such policies and bonds.  Target has no knowledge of any threatened
termination of, or material premium increase with respect to, any of such
policies.

                 2.18     Compliance With Laws.  To Target's knowledge, Target
has complied with, is not in violation of, and has not received any notices of
violation with respect to, any federal, state, local or foreign statute, law or
regulation with respect to the conduct of its business, or the ownership or
operation of its business, except for such violations or failures to comply as
could not be reasonably expected to have a Material Adverse Effect on Target.

                 2.19     Minute Books.  The minute books of Target made
available to Acquiror contain a complete and accurate summary of all meetings
of directors and shareholders or actions by written consent since the time of
incorporation of Target through the date of this Agreement, and reflect all
transactions referred to in such minutes accurately in all material respects.

                   REPRESENTATIONS AND WARRANTIES OF ACQUIROR

                 Except as disclosed in a document of even date herewith and

Agreement and specifically referring to the relevant section and subsection of
this Article III (the "Acquiror Disclosure Schedule"), Acquiror represents and

                 3.1      Organization, Standing and Power.  Each of Acquiror
and its subsidiaries is a corporation duly organized, validly existing and in
good standing under the laws of its jurisdiction of organization.  Each of
Acquiror and its subsidiaries has the corporate power to own its properties and
to carry on its business as now being conducted and as proposed to be conducted
and is duly qualified to do business and is in good standing in each
jurisdiction in which the failure to be so qualified and in good standing would
have a Material Adverse Effect on Acquiror.  Acquiror has delivered a true and
correct copy of the Articles of Incorporation and Bylaws or other charter

Neither Acquiror nor any of its subsidiaries is in violation of any of the

nonassessable.  All of the outstanding shares of capital stock of each such
subsidiary are owned by Acquiror free and clear of all liens, charges, claims
or encumbrances or rights of others.  There are no outstanding subscriptions,
options, warrants, puts, calls, rights, exchangeable or convertible securities
or other commitments or agreements of any character relating to the issued or
unissued capital stock or other securities of any such subsidiary, or otherwise

pursuant to this Agreement, the Acquiror Stock Option Plans there are no other
options, warrants, calls, rights, commitments or agreements of any character to
which Acquiror is a party or by which it is bound obligating Acquiror to issue,
deliver, sell, repurchase or redeem, or cause to be issued, delivered, sold,
repurchased or redeemed, any shares of the capital stock of Acquiror or
obligating Acquiror to grant, extend or enter into any such option, warrant,
call, right, commitment or agreement.  The shares of Acquiror Common Stock to

                 3.3      Authority.  Acquiror has all requisite corporate
power and authority to enter into this Agreement and to consummate the
transactions contemplated hereby.  The execution and delivery of this Agreement
and the consummation of the transactions contemplated hereby have been duly
authorized by all necessary corporate action on the part of Acquiror.  This
Agreement has been duly executed and delivered by Acquiror and constitutes the
valid and binding obligation of Acquiror enforceable against Acquiror in

bankruptcy, insolvency, moratorium or other similar laws affecting or relating
to creditors' rights generally, and is subject to general principles of equity.
The execution and delivery of this Agreement do not, and the consummation of
the transactions contemplated hereby will not, conflict with, or result in any
violation of, or default under (with or without notice or lapse of time, or
both), or give rise to a right of termination, cancellation or acceleration of
any material obligation or loss of a material benefit under (i) any provision
of the Articles of Incorporation or Bylaws of Acquiror or any of its
subsidiaries, as amended, or (ii) any material mortgage, indenture, lease,

Stock issuable upon conversion of the Target Common Stock in the Merger and
upon exercise of the options under the Target Stock Option Plans assumed by
Acquiror, and (vi) such other consents, authorizations, filings, approvals and
registrations which, if not obtained or made, would not have a Material Adverse
Effect on Acquiror and would not prevent, materially or delay any of the
transactions contemplated by this Agreement.

                 3.4      SEC Documents; Financial Statements.  Acquiror has
made available to Target a true and complete copy of each statement, report,
registration statement (with the prospectus in the form filed pursuant to Rule
424(b) of the Securities Act), definitive proxy statement, and other filing
filed with the SEC by Acquiror since November 21, 1995, and, prior to the
Effective Time, Acquiror will have furnished Target with true and complete
copies of any additional documents filed with the SEC by Acquiror prior to the
Effective Time (collectively, the "Acquiror SEC Documents").  In addition,
Acquiror has made available to Target all exhibits to the Acquiror SEC
Documents filed prior to the date hereof, and will promptly make available to
Target all exhibits to any additional Acquiror SEC Documents filed prior to the
Effective Time.  All documents required to be filed as exhibits to the Acquiror
SEC Documents have been so filed, and all material contracts so filed as
exhibits are in full force and effect, except those which have expired in
accordance with their terms, and neither Acquiror nor any of its subsidiaries
is in default thereunder.  As of their respective filing dates, the Acquiror
SEC Documents complied in all material respects with the requirements of the
Securities Exchange Act of 1934, as amended (the "Exchange Act") and the
Securities Act, and none of the Acquiror SEC Documents contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements made therein, in light of
the circumstances in which they were made, not misleading, except to the extent
corrected by a subsequently filed Acquiror SEC Document prior to the date
hereof.  The financial statements of Acquiror, including the notes thereto,
included in the Acquiror SEC Documents (the "Acquiror Financial Statements")
were complete and correct in all material respects as of their respective
dates, complied as to form in all material respects with applicable accounting
requirements and with the published rules and regulations of the SEC with
respect thereto as of their respective dates, and have been prepared in
accordance with generally accepted accounting principles applied on a basis
consistent throughout the periods indicated and consistent with each other
(except as may be indicated in the notes thereto or, in the case of unaudited
statements included in Quarterly Reports on Form 10-Qs, as permitted by Form
10-Q of the SEC).  The Acquiror Financial Statements fairly present the
consolidated financial condition and operating results of Acquiror and its
subsidiaries at the dates and during the periods indicated therein (subject, in
the case of unaudited statements, to normal, recurring year-end adjustments).
There has been no change in Acquiror accounting policies except as described in
the notes to the Acquiror Financial





                                      23.

or 15(d) of the Exchange Act during the 12 calendar months prior to the date
hereof.

                 3.5      Absence of Certain Changes.  Since January 24, 1997,
(the "Acquiror Balance Sheet Date"), Acquiror has conducted its business in the
ordinary course consistent with past practice and there has not occurred: (i)
any change, event or condition (whether or not covered by insurance) that has

Effect to Acquiror; (ii) any acquisition, sale or transfer of any material
asset of Acquiror or any of its subsidiaries other than in the ordinary course
of business and consistent with past practice; (iii) any change in accounting
methods or practices (including any change in depreciation or amortization
policies or rates) by Acquiror or any revaluation by Acquiror of any of its
assets; (iv) any declaration, setting aside, or payment of a dividend or other
distribution with respect to the shares of Acquiror, or any direct or indirect
redemption, purchase or other acquisition by Acquiror of any of its shares of
capital stock; (v) any material contract entered into by Acquiror, other than
in the ordinary course of business and as provided to Target, or any material
amendment or termination of, or default under, any material contract to which
Acquiror is a party or by which it is bound; (vi) any amendment or change to
Acquiror's Articles of Incorporation or Bylaws; or (vii) any negotiation or
agreement by Acquiror or any of its subsidiaries to do any of the things
described in the preceding clauses (i) through (vi) (other than negotiations
with Target and its representatives regarding the transactions contemplated by
this Agreement).

                 3.6      Absence of Undisclosed Liabilities.  Acquiror has no
material obligations or liabilities of any nature (matured or unmatured, fixed
or contingent) other than (i) those set forth or adequately provided for in the
Balance Sheet included in Acquiror's Quarterly Report on Form 10-Q for the
period ended January 24, 1997 (the "Acquiror Balance Sheet"), (ii) those
incurred in the ordinary course of business and not required to be set forth in
the Acquiror Balance Sheet under generally accepted accounting principles, and
(iii) those incurred in the ordinary course of business since the Acquiror
Balance Sheet Date and consistent with past practice.

                 3.7      Litigation.  There is no private or governmental
action, suit, proceeding, claim, arbitration or investigation pending before
any agency, court or tribunal, foreign or domestic, or, to the knowledge of
Acquiror or any of its subsidiaries, threatened against Acquiror or any of its
subsidiaries or any of their respective properties or any of their respective
officers or directors (in their capacities as such) that, individually or in
the aggregate, could reasonably be expected to have a Material Adverse Effect
on Acquiror.  There is no judgment, decree or order against Acquiror or any of
its subsidiaries or, to the knowledge of Acquiror or any of its subsidiaries,
any of their respective directors or officers (in their capacities as such)
that could prevent, enjoin, or materially alter or delay any of the





                                      24.
<PAGE>   30
transactions contemplated by this Agreement, or that could reasonably be
expected to have a Material Adverse Effect on Acquiror.

                 3.8      Governmental Authorization.  Acquiror and each of its
subsidiaries have obtained each federal, state, county, local or foreign

subsidiaries has complied with, are not in violation of, and have not received
any notices of violation with respect to, any federal, state, local or foreign

incurred, nor will it incur, directly or indirectly, any liability for

or any similar charges in connection with this Agreement or any transaction
contemplated hereby.

                 3.11     Information Statement.  The information supplied by
Acquiror for inclusion in the Information Statement shall not, on the date the
Information Statement is first mailed to Target's shareholders, at the time of
the Written Consent and at the Effective Time, contain any statement which, at
such time, is false or misleading with respect to any material fact, or omit to
state any material fact necessary in order to make the statements therein, in
light of the circumstances under which it is made, not false or misleading; or
omit to state any material fact necessary to correct any statement in any
earlier communication with respect to the solicitation of the Written Consent
which has become false or misleading.  Notwithstanding the foregoing, Acquiror
makes no representation, warranty or covenant with respect to any information
supplied by Target which is contained in any of the foregoing documents.

                             ADDITIONAL AGREEMENTS

                 5.1      Preparation of Information Statement.  Target shall
have prepared, with the cooperation of Acquiror, an Information Statement for
the shareholders of Target to approve this Agreement, the Agreement of Merger
and the transactions contemplated hereby and thereby.  The Information
Statement shall constitute a disclosure document for the offer and issuance of
the shares of Acquiror Common Stock to be received by the holders of Target
Capital Stock in the Merger.  Acquiror and Target shall each use reasonable
commercial efforts to cause the Information Statement to comply with applicable
federal and state securities laws requirements.  Each of Acquiror and Target
agrees to provide promptly to the other such information concerning its
business and financial statements and affairs as, in the reasonable judgment of
the providing party or its counsel, may be required or appropriate for
inclusion in the Information Statement, or in any amendments or supplements
thereto, and to cause its counsel and auditors to cooperate with the other's
counsel and auditors in the preparation of the Information Statement.  Target
will promptly advise Acquiror, and Acquiror will promptly advise Target, in
writing if at any time prior to the Effective Time either Target or Acquiror
shall obtain knowledge of any facts that might make it necessary or appropriate
to amend or supplement the Information Statement in order to make the
statements contained or incorporated by reference therein not misleading or to
comply with applicable law.  The Information Statement shall contain the
recommendation of the Board of Directors of Target that the Target shareholders
approve the Merger and this Agreement and the conclusion of the Board of
Directors that the terms and conditions of the Merger are in the best interests
of the shareholders of Target; provided that such recommendation may not be
included or may be withdrawn if previously included if Target's Board of
Directors believes in good faith that a





                                      30.
<PAGE>   36
superior Takeover Proposal has been made and, upon advice of its outside legal
counsel, shall determine that to include such recommendation or not withdraw
such recommendation if previously included would constitute a breach of the
Board's fiduciary duty under applicable law.  Anything to the contrary
contained herein notwithstanding, Target shall not include in the Information
Statement any information with respect to Acquiror or its affiliates or
associates, the form and content of which information shall not have been
approved by Acquiror prior to such inclusion.

                 5.2      Written Consent of Shareholders.  Target shall,
concurrent with the execution of this Agreement, take all action prior to or at

Incorporation and Bylaws to solicit Written Consents.  Subject to its fiduciary
duties, Target shall take all action necessary or advisable to secure the vote
or consent of shareholders required to effect the Merger.

                 5.3      Access to Information.

                          (a)     Target shall afford Acquiror and its

business hours during the period prior to the Effective Time to (i) all of

other information concerning the business, properties and personnel of Target
as Acquiror may reasonably request.  Target agrees to provide to Acquiror and
its accountants, counsel and other representatives copies of internal financial

records, and (ii) all other information concerning the business, properties and
personnel of Acquiror and its subsidiaries as Target may reasonably request.
Acquiror agrees to provide to Target and its accountants, counsel and other
representatives copies of internal financial statements promptly upon request.

                          (b)     Subject to compliance with applicable law,
from the date hereof until the Effective Time, each of Acquiror and Target
shall confer on a regular and frequent basis with one or more representatives
of the other party to report operational matters of materiality and the general
status of ongoing operations.

                          (c)     No information or knowledge obtained in any
investigation pursuant to this Section 5.2 shall affect or be deemed to modify
any representation or warranty contained herein or the conditions to the
obligations of the parties to consummate the Merger.

                 5.4      Confidentiality.  The parties acknowledge that
Acquiror and Target have previously executed a non-disclosure agreement on

                                      31.
<PAGE>   37
Agreement"), which Confidentiality Agreement shall continue in full force and
effect in accordance with its terms.

                 5.5      Public Disclosure.  Unless otherwise permitted by
this Agreement, Acquiror and Target shall consult with each other before
issuing any press release or otherwise making any public statement or making
any other public (or non-confidential) disclosure (whether or not in response
to an inquiry) regarding the terms of this Agreement and the transactions
contemplated hereby, and neither shall issue any such press release or make any
such statement or disclosure without the prior approval of the other (which
approval shall not be unreasonably withheld), except as may be required by law
or by obligations pursuant to any listing agreement with any national
securities exchange or with the NASD.

                 5.6      Consents; Cooperation.

                          (a)     Each of Acquiror and Target shall promptly
apply for or otherwise seek, and use reasonable best efforts to obtain, all
consents and approvals required to be obtained by it for the consummation of
the Merger and shall use reasonable best efforts to obtain all necessary
consents, waivers and approvals under any of its material contracts in
connection with the Merger for the assignment thereof or otherwise.  The
parties hereto will consult and cooperate with one another, and consider in
good faith the views of one another, in connection with any analyses,
appearances, presentations, memoranda, briefs, arguments, opinions and
proposals made or submitted by or on behalf of any party hereto in connection
with proceedings under any other federal or state antitrust or fair trade law.

                          (b)     Each of Acquiror and Target further agrees to
notify the other promptly of the receipt of any comments from any government
officials for amendments or supplements to any filing or for additional
information and will supply the other with copies of all correspondence between
such company or any of its representatives, on the one hand, and the government
officials, on the other hand, with respect to such filing in accordance with an
appropriate confidentiality agreement between the parties.  Whenever any event
occurs which is required to be set forth in an amendment or supplement to any
such filing, Acquiror or Target, as the case may be, shall promptly inform the
other of such occurrence and cooperate in filing with the government.

                          (c)     Notwithstanding anything to the contrary in
Section 5.6(a), (i) neither Acquiror nor any of it subsidiaries shall be
required to divest any of their respective businesses, product lines or assets,
or to take or agree to take any other action or agree to any limitation and
(ii) Target shall not be required to divest any of its business, product lines
or assets, or to take or agree to take any other action or agree to any
limitation.

                 5.7      Shareholder Agreements.  Schedule 5.7 sets forth

                                      32.
<PAGE>   38
promulgated under the Securities Act ("Rule 145").  Target shall provide
Acquiror such information and documents as Acquiror shall reasonably request
for purposes of reviewing such list.  Target shall use its best efforts to
deliver or cause to be delivered to Acquiror, concurrently with the execution
of this Agreement from each of the shareholders of Target, an executed
Shareholder Agreement in the form attached hereto as Exhibit B.  Acquiror shall
be entitled to place appropriate legends on the certificates evidencing any
Acquiror Common Stock to be received by Affiliates of Target pursuant to the
terms of this Agreement, and to issue appropriate stop transfer instructions to
the transfer agent for Acquiror Common Stock, consistent with the terms of such
Shareholder Agreement.

                 5.8      FIRPTA.  Target shall, on the Closing Date, provide
Acquiror with a properly executed Foreign Investment and Real Property Tax Act
of 1980 ("FIRPTA") Notification Letter, substantially in the form of Exhibit C
attached hereto, which states that shares of capital stock of Target do not
constitute "United States real property interests" under Section 897(c) of the
Code, for purposes of satisfying Acquiror's obligations under Treasury
Regulation Section 1.1445-2(c)(3). In addition, simultaneously with delivery of
such Notification Letter, Target shall have provided to Acquiror, as agent for
Target, a form of notice to the Internal Revenue Service in accordance with the
requirements of Treasury Regulation Section 1.897-2(h)(2) and substantially in
the form of Exhibit C attached hereto along with written authorization for
Acquiror to deliver such notice form to the Internal Revenue Service on behalf
of Target upon the Closing of the Merger.

                 5.9      Legal Requirements.  Each of Acquiror and Target
will, and will cause any subsidiaries to, take all reasonable actions necessary
to comply promptly with all legal requirements which may be imposed on them
with respect to the consummation of the transactions contemplated by this
Agreement and will promptly cooperate with and furnish information to any party
hereto necessary in connection with any such requirements imposed upon such
other party in connection with the consummation of the transactions
contemplated by this Agreement and will take all reasonable actions necessary
to obtain (and will cooperate with the other parties hereto in obtaining) any
consent, approval, order or authorization of, or any registration, declaration
or filing with, any Governmental Entity or other person, required to be
obtained or made in connection with the taking of any action contemplated by
this Agreement.

                 5.10     Blue Sky Laws.  Acquiror shall take such steps as may
be necessary to comply with the securities and blue sky laws of all
jurisdictions which are applicable to the issuance of the Acquiror Common Stock
in connection with the Merger.  Target shall use its best efforts to assist
Acquiror as may be necessary to comply with the securities and blue sky laws of
all jurisdictions which are applicable in connection with the issuance of
Acquiror Common Stock in connection with the Merger.





                                      33.
<PAGE>   39
                 5.11     Employee Benefit Plans.  At the Effective Time, the
Target Stock Option Plan and each outstanding option to purchase shares of
Target Common Stock under the Target Stock Option Plan, whether vested or
unvested, will be assumed by Acquiror and any outstanding repurchase right
shall be assigned to Acquiror.  Schedule 5.11 hereto sets forth a true and
complete list as of the date hereof of all holders of outstanding options under
the Target Stock Option Plan including the number of shares of Target Capital
Stock subject to each such option, the exercise or vesting schedule, the
exercise price per share and the term of each such option.  Each such option so
assumed by Acquiror under this Agreement shall continue to have, and be subject
to, the same terms and conditions set forth in the Target Stock Option Plan
immediately prior to the Effective Time, except that (i) such option will be
exercisable for that number of whole shares of Acquiror Common Stock equal to
the product of the number of shares of Target Common Stock that were issuable
upon exercise of such option immediately prior to the Effective Time multiplied
by the Exchange Ratio and rounded down to the nearest whole number of shares of
Acquiror Common Stock, and (ii) the per share exercise price for the shares of
Acquiror Common Stock issuable upon exercise of such assumed option will be
equal to the quotient determined by dividing the exercise price per share of
Target Common Stock at which such option was exercisable immediately prior to
the Effective Time by the Exchange Ratio, rounded up to the nearest whole cent.
Consistent with the terms of the Target Stock Option Plan and the documents
governing the outstanding options under such Plans, the Merger will not
terminate any of the outstanding options under the Target Stock Option Plan
(other than outstanding options that have been granted to nonemployee members
of Target's Board of Directors) or accelerate the exercisability or vesting of
such options or the shares of Acquiror Common Stock which will be subject to
those options upon the Acquiror's assumption of the options in the Merger.  It
is the intention of the parties that the options so assumed by Acquiror qualify

of this Agreement as provided in Section 7.1, this Agreement shall forthwith
become void and there shall be no liability or obligation on the part of

                 8.3      Interpretation.  When a reference is made in this
Agreement to Exhibits or Schedules, such reference shall be to an Exhibit or
Schedule to this Agreement unless otherwise indicated.  The words "include,"
"includes" and "including" when used herein shall be deemed in each case to be
followed by the words "without limitation." The phrase "made available" in this
Agreement shall mean that the information referred to has been made available
if requested by the party to whom such information is to be made available.
The phrases "the date of this Agreement," "the date hereof," and terms of
similar import, unless the context otherwise requires, shall be deemed to refer
to March 17, 1997.  The table of contents and headings contained in this
Agreement are for reference purposes only and shall not affect in any way the
meaning or interpretation of this Agreement.

                 8.4      Indemnification.  After the Effective Time, Acquiror
will, and will cause the Surviving Corporation to, indemnify and hold harmless
the present and former officers, directors, employees and agents of Target (the
"Indemnified Parties") in respect of matters arising out of acts or omissions
occurring on or prior to the Effective Time to the full extent permitted by law
and to the full extent provided under Target's Articles of Incorporation and
Bylaws or any indemnification agreement with Target officers and directors to
which Target is a party, in each case in effect on the date hereof.  Without
limitation of the foregoing, in the event any such Indemnified Party is or
becomes involved in any capacity in any action, proceeding or investigation in
connection with any matter relating to this Agreement or the transactions
contemplated hereby occurring on or prior to the Effective Time, Acquiror shall
pay as incurred such Indemnified Party's reasonable legal and other expenses
(including the cost of any investigation and preparation) incurred in
connection therewith.

                 8.5      Counterparts.  This Agreement may be executed in one
or more counterparts, all of which shall be considered one and the same
agreement and shall become effective when one or more counterparts have been
signed by each of the parties and delivered to the other parties, it being
understood that all parties need not sign the same counterpart.

                 8.6      Entire Agreement; Nonassignability; Parties in
Interest.  This Agreement and the documents and instruments and other
agreements specifically referred to herein or delivered pursuant hereto,
including the Exhibits, the Schedules, including the Target Disclosure Schedule
and the Acquiror Disclosure Schedule (a) constitute the entire agreement among
the parties with respect to the subject matter hereof and supersede all prior
agreements

and understandings, both written and oral, among the parties with respect to
the subject matter hereof, except for the Confidentiality Agreement, which
shall continue in full force and effect, and shall survive any termination of
this Agreement or the Closing, in accordance with its terms; (b) are not
intended to confer upon any other person any rights or remedies hereunder,
except as specifically set forth herein; and (c) shall not be assigned by
operation of law or otherwise except as otherwise specifically provided.

                 8.7      Severability.  In the event that any provision of
this Agreement, or the application thereof, becomes or is declared by a court
of competent jurisdiction to be illegal, void or unenforceable, the remainder
of this Agreement will continue in full force and effect and the application of
such provision to other persons or circumstances will be interpreted so as
reasonably to effect the intent of the parties hereto.  The parties further
agree to replace such void or unenforceable provision of this Agreement with a
valid and enforceable provision that will achieve, to the extent possible, the
economic, business and other purposes of such void or unenforceable provision.

                 8.8      Remedies Cumulative.  Except as otherwise provided
herein, any and all remedies herein expressly conferred upon a party will be
deemed cumulative with and not exclusive of any other remedy conferred hereby,
or by law or equity upon such party, and the exercise by a party of any one
remedy will not preclude the exercise of any other remedy.

                 8.9      Governing Law.  This Agreement shall be governed by
and construed in accordance with the laws of California, without giving effect
to principles of conflicts of law.  Each of the parties hereto irrevocably
consents to the exclusive jurisdiction of any court located within Santa Clara
or San Mateo County, State of California, in connection with any matter based
upon or arising out of this Agreement or the matters contemplated herein,
agrees that process may be served upon them in any manner authorized by the
laws of the State of California for such persons and waives and covenants not
to assert or plead any objection which they might otherwise have to such
jurisdiction and such process.

                 8.10     Rules of Construction.  The parties hereto agree that
they have been represented by counsel during the negotiation, preparation and
execution of this Agreement and, therefore, waive the application of any law,
regulation, holding or rule of construction providing that ambiguities in an
agreement or other document will be construed against the party drafting such
agreement or document.

                              AGREEMENT OF MERGER

                                       OF

                            NETWORK APPLIANCE, INC.

                                      AND

                        INTERNET MIDDLEWARE CORPORATION

                 This Agreement of Merger, dated as of the 17th day of March,
1997 ("Merger Agreement"), by and between Network Appliance, Inc., a California
corporation ("Acquiror"), and Internet Middleware Corporation, a California
corporation ("Target").

                                    RECITALS

         A.      Target was incorporated in the State of California on May 6,
1996 and on the date hereof has an authorized capital stock of 25,000,000
shares of Common Stock, no par value ("Target Common Stock").  On the date
hereof 4,992,500 shares of Target Common Stock are outstanding and 424,290
shares of Target Common Stock are subject to issuance upon the exercise of
outstanding stock options ("Target Rights").

         B.       Acquiror was incorporated in the State of California on April
21, 1992 and on the date hereof has an authorized capital stock of 55,000,000
shares of Common Stock ("Acquiror Common Stock") and 5,000,000 shares of
Preferred Stock ("Acquiror Preferred Stock").  At the close of business on
March 14, 1997, 15,753,147 shares of Acquiror Common Stock were outstanding,
and 2,102,236 shares of Acquiror Common Stock were subject to issuance upon the
exercise of outstanding stock options ("Acquiror Rights").

         C.      Acquiror and Target have entered into an Agreement and Plan of
Reorganization (the "Agreement and Plan of Reorganization") providing for
certain representations, warranties, covenants and agreements in connection
with the transactions contemplated hereby.  This Merger Agreement and the
Agreement and Plan of Reorganization are intended to be construed together to
effectuate their purpose.

         D.      The Boards of Directors of Target and Acquiror deem it
advisable and in their mutual best interests and in the best interests of the
shareholders of Target and Acquiror, respectively, that Target be acquired by
Acquiror through a merger ("Merger") of Target with and into Acquiror.





<PAGE>   2
         E.      The Boards of Directors of Acquiror and Target and the
shareholders of Target have approved the Merger.

                                   AGREEMENTS

                 The parties hereto hereby agree as follows:

                 1.        Target shall be merged with and into Acquiror, and
Acquiror shall be the surviving corporation.

                 2.       The Merger shall become effective at such time (the
"Effective Time" of the Merger) as this Merger Agreement and the officers'
certificates of Acquiror and Target are filed with the Secretary of State of
the State of California pursuant to Section 1103 of the California Corporations
Code.

                 3.       At the Effective Time of the Merger (i) all shares of
Target Common Stock that are owned directly or indirectly by Target, Acquiror
or any subsidiary of Acquiror shall be cancelled, and no securities of Acquiror
or other consideration shall be delivered in exchange therefor, (ii) each other
share of Target Common Stock issued and outstanding shall be converted
automatically into and exchanged for .0345267 of a share of Acquiror Common
Stock, and (iii) each of the Target Rights (as defined in the Agreement and
Plan of Reorganization) shall be converted into the right to purchase Acquiror
Common Stock as set forth more fully in the Agreement and Plan of
Reorganization.

                 4.       All shareholders of Target shall have approved the
Merger prior to the Effective Time and no shareholders shall have elected to
exercise dissenters' rights in accordance with Chapter 13 of the California
Corporations Code.

                 5.       Notwithstanding any other term or provision hereof
but subject to the proviso in the second sentence of Section 3, no fractional
shares of Acquiror Common Stock shall be issued, but in lieu thereof each
holder of Target Common Stock who would otherwise, but for rounding as provided
herein, be entitled to receive a fraction of a share of Acquiror Common Stock
shall receive from Acquiror an amount of cash equal to the per share market
value of Acquiror Common Stock (deemed to be $39.30) multiplied by the fraction
of a share of Acquiror Common Stock to which such holder would otherwise be
entitled.  The fractional share interests of each Target shareholder shall be
aggregated, so that no Target shareholder shall receive cash in an amount
greater than the value of one full share of Acquiror Common Stock.

                 6.       The conversion of Target Common Stock into Acquiror
Common Stock as provided by this Merger Agreement shall occur automatically at
the Effective Time of the Merger without action by the holders thereof.  Each
holder of Target Common Stock shall thereupon be entitled to receive shares of
Acquiror Common Stock in accordance with Section





                                       2.
<PAGE>   3
3.  Such shareholder shall receive certificates that represent that number of
shares of Acquiror Common Stock in accordance with the following procedures:

                          (a)     As soon as practicable after the Effective
Time of the Merger, Acquiror shall make available for exchange in accordance
with Section 3, through such reasonable procedures as Acquiror may adopt, the
shares of Acquiror Common Stock issuable pursuant to Section 3 in exchange for
outstanding shares of Target Common Stock.

                          (b)     Promptly after the Effective Time of the
Merger, the Exchange Agent (as defined in Section 1.6 of the Agreement and Plan
of Reorganization) shall mail to each holder of record of a certificate or
certificates which immediately prior to the Effective Time of the Merger
represented outstanding shares of Target Common Stock (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the certificates shall pass, only upon receipt of the
certificates to the Exchange Agent and shall be in such form and have such
other provisions as Acquiror may reasonably specify) and (ii) instructions for
use in effecting the surrender of the certificates in exchange for certificates
evidencing Acquiror Common Stock.  Upon surrender of a certificate for
cancellation to the Exchange Agent or to such other agent or agents as may be
appointed by Acquiror, together with such letter of transmittal, duly executed,
the holder of such certificate shall be entitled to receive in exchange
therefor the number of shares of Acquiror Common Stock to which the holder of
Target Common Stock is entitled pursuant to Section 3 hereof and is represented
by the certificate so surrendered, along with a check representing the value of
any fractional shares as defined pursuant to Section 5 hereof.  The certificate
so surrendered shall forthwith be cancelled.  In the event of a transfer of
ownership of Target Common Stock which is not registered in the transfer
records of Target, Acquiror Common Stock may be delivered to a transferee if
the certificate representing such Target Common Stock is presented to Acquiror
and accompanied by all documents required to evidence and effect such transfer
and to evidence that any applicable stock transfer taxes have been paid.  Until
surrendered as contemplated by this Section 6, each certificate shall be deemed
at any time after the Effective Time of Merger to represent the right to
receive upon such surrender such number of shares of Acquiror Common Stock as
provided by Section 3 and the provisions of applicable law.

                          (c)     No dividends on the shares of Acquiror Common
Stock shall be paid to the holder of any unsurrendered certificate until the
holder of record of such certificate shall surrender such certificate.  Subject
to the effect, if any, of applicable escheat and other laws, following
surrender of any certificate, there shall be delivered to the person entitled
thereto, without interest, the amount of dividends theretofore paid with
respect to the shares of Acquiror Common Stock so withheld as of any date
subsequent to the Effective Time of the Merger and prior to such date of
delivery.

                          (d)     All shares of Acquiror Common Stock delivered
upon the surrender for exchange of Target Common Stock in accordance with the
terms hereof shall be deemed to have been delivered in full satisfaction of all
rights pertaining to such Target Common Stock. There shall be no further
registration of transfers on the stock transfer books





                                       3.
<PAGE>   4
of the Target of the Target Common Stock that was outstanding immediately prior
to the Effective Time of the Merger.  If, after the Effective Time of the
Merger, certificates are presented to Acquiror for any reason, they shall be
cancelled and exchanged as provided in this Section 6.

                 7.       At the Effective Time of the Merger, the separate
existence of Target shall cease, and Acquiror shall succeed, without other
transfer, to all of the rights and properties of Target and shall be subject to
all the debts and liabilities thereof in the same manner as if Acquiror had
itself incurred them.  All rights of creditors and all liens upon the property
of each corporation shall be preserved unimpaired, provided that such liens
upon property of Target shall be limited to the property affected thereby
immediately prior to the Effective Time of the Merger.

                 8.       This Merger Agreement is intended as a plan of
reorganization within the meaning of Section 368 of the Internal Revenue Code
of 1986, as amended.

                 9.       (a)     The Restated Articles of Incorporation of
Acquiror shall be the Restated Articles of Incorporation of Acquiror as the
surviving corporation (the "Surviving Corporation") after the Merger unless
thereafter amended.

                          (b)     The Bylaws of Acquiror in effect immediately
prior to the Effective Time shall be the Bylaws of the Surviving Corporation
unless and until amended or repealed as provided by applicable law, the
Articles of Incorporation of the Surviving Corporation and such Bylaws.

                          (c)     The directors and officers of Acquiror
immediately prior to the Effective Time shall be the directors and officers of
the Surviving Corporation.

                 10.      (a)     Notwithstanding the approval of this Merger
Agreement by the shareholders of Target, this Merger Agreement may be
terminated at any time prior to the Effective Time of the Merger by mutual
agreement of the Boards of Directors of Acquiror and Target.

                          (b)     Notwithstanding the approval of this Merger
Agreement by the shareholders of Target, this Merger Agreement shall terminate
forthwith in the event that the Agreement and Plan of Reorganization shall be
terminated as therein provided.

                          (c)     In the event of the termination of this
Merger Agreement as provided above, this Merger Agreement shall forthwith
become void, and there shall be no liability on the part of Target or Acquiror
or their respective officers or directors, except as otherwise provided in the
Agreement and Plan of Reorganization.

                          (d)     This Merger Agreement may be signed in one or
more counterparts, each of which shall be deemed an original and all of which
shall constitute one agreement.

                          (e)     This Merger Agreement may be amended by the
parties hereto any time before or after approval hereof by the shareholders of
Target, but, after such approval, no amendments shall be made which by law
require the further approval of such shareholders without obtaining such
approval.  This Merger Agreement may not be amended except by an instrument in
writing signed on behalf of each of the parties hereto.

                             STOCK OPTION AGREEMENT



RECITALS

I.      The Board has adopted the Plan for the purpose of retaining the services
of selected Employees, non-employee members of the Board or the board of
directors of any Parent or Subsidiary and consultants and other independent
advisors who provide services to the Corporation (or any Parent or Subsidiary).

        A.      Optionee is to render valuable services to the Corporation (or a
Parent or Subsidiary), and this Agreement is executed pursuant to, and is
intended to carry out the purposes of, the Plan in connection with the
Corporation's grant of an option to Optionee.

        B.      All capitalized terms in this Agreement shall have the meaning
assigned to them in the attached Appendix.

                 NOW, THEREFORE, it is hereby agreed as follows:

                 1.       GRANT OF OPTION.  The Corporation hereby grants to
Optionee, as of the Grant Date, an option to purchase up to the number of
Option Shares specified in the Grant Notice.  The Option Shares shall be
purchasable from time to time during the option term specified in Paragraph 2
at the Exercise Price.

                 2.       OPTION TERM.  This option shall have a term of ten
(10) years measured from the Grant Date and shall accordingly expire at the
close of business on the Expiration Date, unless sooner terminated in
accordance with Paragraph 5 or 6.

                 3.       LIMITED TRANSFERABILITY.  This option shall be
neither transferable nor assignable by Optionee other than by will or by the
laws of descent and distribution following Optionee's death and may be
exercised, during Optionee's lifetime, only by Optionee.

                 4.       DATES OF EXERCISE.  This option shall become
exercisable for the Option Shares in one or more installments as specified in
the Grant Notice.  As the option becomes exercisable for such installments,
those installments shall accumulate and the option shall remain exercisable for
the accumulated installments until the Expiration Date or sooner termination of
the option term under Paragraph 5 or 6.
<PAGE>   2

                 5.       CESSATION OF SERVICE.  The option term specified in
Paragraph 2 shall terminate (and this option shall cease to be outstanding)
prior to the Expiration Date should any of the following provisions become
applicable:

                               (i)         Should Optionee cease to remain in
         Service for any reason (other than death or Permanent Disability)
         while this option is outstanding, then Optionee shall have only until
         the later of the following events in which to exercise this option:
         (i) the end of the six (6)-month period measured from the date of such
         cessation of Service or (ii) the end of the seventy eight (78)-month
         period measured from the Grant Date.  Upon the occurrence of the later
         of such events, this option shall terminate and cease to be
         outstanding.

                              (ii)         Should Optionee die while this
         option is outstanding, then the personal representative of Optionee's
         estate or the person or persons to whom the option is transferred
         pursuant to Optionee's will or in accordance with the laws of descent
         and distribution shall have the right to exercise this option.  Such
         right shall lapse, and this option shall cease to be outstanding, upon
         the later of the following events: (A) the expiration of the twelve
         (12)-month period measured from the date of Optionee's death or (B)
         the end of the seventy eight (78)-month period measured from the Grant
         Date.  Upon the occurrence of the later of such events, this option
         shall terminate and cease to be outstanding.

                             (iii)         Should Optionee cease Service by
         reason of Permanent Disability while this option is outstanding, then
         Optionee shall have only until the later of the following events in
         which to exercise this option: (i) the end of the twelve (12)-month
         period measured from the date of such cessation of Service or (ii) the
         end of the seventy eight (78)-month period measured from the Grant
         Date.  Upon the occurrence of the later of such events, this option
         shall terminate and cease to be outstanding.

                               (iv)        In no event shall this option be 
         exercisable at any time after the Expiration Date.

                                (v)        On each occasion during the
         applicable post-Service exercise period on which this option is
         exercised, the option may not be exercised for more than the number of
         Option Shares for which the option is at that time exercisable in
         accordance with the applicable exercise schedule set forth in the
         Grant Notice.

<PAGE>   3
                 6.       SPECIAL ACCELERATION OF OPTION.

                          (a)     This option, to the extent outstanding at the
time of a Corporate Transaction but not otherwise fully exercisable, shall
automatically accelerate so that this option shall, immediately prior to the
effective date of the Corporate Transaction, become exercisable for all of the
Option Shares at the time subject to the option and may be exercised for any or
all of those Option Shares as fully-vested shares of Common Stock.  No such
acceleration of this option, however, shall occur if and to the extent (i) this
option is, in connection with the Corporate Transaction, either to be assumed
by the successor corporation (or parent thereof) or to be replaced with a
comparable option to purchase shares of the capital stock of the successor
corporation (or parent thereof) or (ii) this option is to be replaced with a
cash incentive program of the successor corporation which preserves the spread
existing on the Option Shares at the time of the Corporate Transaction (the
excess of the Fair Market Value of those Option Shares over the aggregate
Exercise Price payable for such shares) and provides for subsequent pay-out in
accordance with the option exercise schedule set forth in the Grant Notice.
The determination of option comparability under clause (i) shall be made by the
Plan Administrator, and such determination shall be final, binding and
conclusive.

                          (b)     Immediately following the Corporate
Transaction, this option, to the extent not previously exercised, shall
terminate and cease to be outstanding, except  to the extent assumed by the
successor corporation (or parent thereof) in connection with the Corporate
Transaction.

                          (c)     If this option is assumed in connection with
a Corporate Transaction, then this option shall be appropriately adjusted,
immediately after such Corporate Transaction, to apply to the number and class
of securities which would have been issuable to Optionee in consummation of
such Corporate Transaction had the option been exercised immediately prior to
such Corporate Transaction, and appropriate adjustments shall also be made to
the Exercise Price, provided the aggregate Exercise Price shall remain the
same.

                          (d)     This Agreement shall not in any way affect
the right of the Corporation to adjust, reclassify, reorganize or otherwise
change its capital or business structure or to merge, consolidate, dissolve,
liquidate or sell or transfer all or any part of its business or assets.

                 7.       ADJUSTMENT IN OPTION SHARES.  Should any change be
made to the Common Stock by reason of any stock split, stock dividend,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's
receipt of consideration, appropriate adjustments shall be made to (i) the
total number and/or class of securities subject to this option and (ii) the
Exercise Price in order to reflect such change and thereby preclude a dilution
or enlargement of benefits hereunder.

                 8.       STOCKHOLDER RIGHTS.  The holder of this option shall
not have any stockholder rights with respect to the Option Shares until such
person shall have exercised the option, paid the Exercise Price and become a
holder of record of the purchased shares.

                 9.       MANNER OF EXERCISING OPTION.

                          (a)     In order to exercise this option with respect
to all or any part of the Option Shares for which this option is at the time
exercisable, Optionee (or any other person or persons exercising the option)
must take the following actions:

                                       (i)         Execute and deliver to the
         Corporation a Notice of Exercise for the Option Shares for which the
         option is exercised.

                                       (ii)        Pay the aggregate Exercise
         Price for the purchased shares in one or more of the following forms:

                                        (A)     cash or check made payable to
                 the Corporation;

                                        (B)     shares of Common Stock held by
                 Optionee (or any other person or persons exercising the
                 option) for the requisite period necessary to avoid a charge
                 to the Corporation's earnings for financial reporting purposes
                 and valued at Fair Market Value on the Exercise Date; or

                                        (C)     through a special sale and
                 remittance procedure pursuant to which Optionee (or any other
                 person or persons exercising the option) shall concurrently
                 provide irrevocable written instructions (I) to a
                 Corporation-designated brokerage firm to effect the immediate
                 sale of the purchased shares and remit to the Corporation, out
                 of the sale proceeds available on the settlement date,
                 sufficient funds to cover the aggregate Exercise Price payable
                 for the purchased shares plus all applicable Federal, state
                 and local income and employment taxes required to be withheld
                 by the Corporation by reason of such exercise and (II) to the
                 Corporation to deliver the certificates for the purchased
                 shares directly to such brokerage firm in order to complete
                 the sale transaction.

                          Except to the extent the sale and remittance
                 procedure is utilized in connection with the option exercise,
                 payment of the Exercise Price must accompany the Notice of
                 Exercise delivered to the Corporation in connection with such
                 option exercise.





                                       4.
<PAGE>   5
                                     (iii)         Furnish to the Corporation
         appropriate documentation that the person or persons exercising the
         option (if other than Optionee) have the right to exercise this
         option.

                                     (iv)          Make appropriate
         arrangements with the Corporation (or Parent or Subsidiary employing
         or retaining Optionee) for the satisfaction of all Federal, state and
         local income and employment tax withholding requirements applicable to
         the option exercise.

                          (b)     As soon as practical after the Exercise Date,
the Corporation shall issue to or on behalf of Optionee (or any other person or
persons exercising this option) a certificate for the purchased Option Shares,
with the appropriate legends affixed thereto.  The Corporation will use
commercially reasonable efforts to file with the SEC a registration statement
on Form S-8 covering all shares of Common Stock issuable pursuant to
outstanding options under the Target Stock Option Plan, as defined in the
Agreement and Plan of Reorganization between the Corporation and Internet
Middleware Corporation, dated March 17, 1997 (the "Reorganization Agreement"),
assumed by the Corporation pursuant to the Reorganization Agreement and all
Option Shares pursuant to this Agreement.  Acquiror shall use commercially
reasonable efforts to cause such registration statement to become effective as
promptly as practicable after filing and to keep such registration statement
effective until all of the shares of Common Stock have been sold thereunder.

                          (c)     In no event may this option be exercised for 
any fractional shares.

                 10.      COMPLIANCE WITH LAWS AND REGULATIONS.

                          (a)     The exercise of this option and the issuance
of the Option Shares upon such exercise shall be subject to compliance by the
Corporation and Optionee with all applicable requirements of law relating
thereto and with all applicable regulations of any stock exchange (or the
Nasdaq National Market, if applicable) on which the Common Stock may be listed
for trading at the time of such exercise and issuance.

                          (b)     The inability of the Corporation to obtain
approval from any regulatory body having authority deemed by the Corporation to
be necessary to the lawful issuance and sale of any Common Stock pursuant to
this option shall relieve the Corporation of any liability with respect to the
non-issuance or sale of the Common Stock as to which such approval shall not
have been obtained.  The Corporation, however, shall use its best efforts to
obtain all such approvals.

                 11.      SUCCESSORS AND ASSIGNS.  Except to the extent
otherwise provided in Paragraphs 3 and 6, the provisions of this Agreement
shall inure to the benefit of, and be binding upon, the Corporation and its
successors and assigns and Optionee, Optionee's assigns and the legal
representatives, heirs and legatees of Optionee's estate.

                 13.      CONSTRUCTION.  This Agreement and the option
evidenced hereby are made and granted pursuant to the Plan and are in all
respects limited by and subject to the terms of the Plan.  All decisions of the
Plan Administrator with respect to any question or issue arising under the Plan
or this Agreement shall be conclusive and binding on all persons having an
interest in this option.

                 14.      GOVERNING LAW.  The interpretation, performance and
enforcement of this Agreement shall be governed by the laws of the State of
California without resort to that State's conflict-of-laws rules.

              NETWORK APPLIANCE ACQUIRES INTERNET MIDDLEWARE CORP.

             IMC'S WEB PROXY CACHING TECHNOLOGY GREATLY ACCELERATES
                     USER ACCESS TO INTERNET/INTRANET DATA

SANTA CLARA, CALIFORNIA -- MARCH 17, 1997 -- Network Appliance, Inc. (NASDAQ:
NTAP) has signed a definitive purchase agreement under which it has acquired
privately-held Internet Middleware Corporation (IMC).

         Under terms of the purchase agreement, Network Appliance common  stock
and options worth approximately $10.5 million was exchanged for all outstanding
shares and options of IMC.  The acquisition will be treated as a purchase.
Allocation of the purchase price is expected to result in a one-time charge to
Network Appliance's income statement in the fourth quarter of the current
fiscal year of approximately $9.5 million, net of income taxes, related to the
purchase of in-process technology.

         IMC was founded in 1996 by University of Southern California Professor
Peter Danzig, a leading member of a web-caching research project sponsored
primarily by the Advanced Research Projects Agency (ARPA) with additional
support from National Science Foundation (NSF).  The pioneering work, known





<PAGE>   2
as Harvest cache, showed that Web proxy caching significantly speeds
Internet/intranet access for users while decreasing the bandwidth needed on the
Internet.  IMC improved the performance in Harvest and prepared it for
commercial application.  IMC and Harvest-based products dominate the market for
Web proxy caching, and are used by more Internet service providers (ISPs) and
large companies worldwide than any other caching product.

         "Proxy-caching technology is a natural fit for NetApp products, which
are already well established in the infrastructure of leading ISPs in North
America and Europe, as well as corporate intranets," said Dan Warmenhoven,
president and CEO of Network Appliance.  "High- bandwidth applications and fast
modems are already straining ISP and corporate networks today, and as bandwidth
availability declines so will access to the data users need.  We can now offer
a superior solution to this problem," he said.

         "We are excited by the IMC-Network Appliance merger," said Mark
Towfiq, president of Intelenet, Inc., which is helping Toshiba America
Information Systems deploy Time Warner's cable modem services across the United
States. "We already use IMC's proxy caching and Network Appliance filer
products to reduce bandwidth costs and improve quality of service as part of
Time Warner's project. We would be very interested in a combination of these
two leading technologies in an appliance product for ease of deployment and
faster performance."

         Network Appliance is a market-leading supplier of dedicated,
network-data access servers, called filers, which enable users on computer
networks to quickly and easily share different types of file data.  The
Company's filers accelerate the performance of applications on a network for
users by dramatically reducing network response times.

         Except for the historical information contained in this announcement,
the discussion in this press release contains certain forward- looking
statements that involve risks and uncertainties.  The Company's actual results
could differ materially from those discussed here.  Factors that could cause or
contribute to





<PAGE>   3
such differences include compliance with accounting rules with regard to the
estimate of the amount to be expensed in the fourth quarter, and those
discussed in "risk factors" in the Company's Annual Report on Form 10K.

         Network Appliance filers deliver shared file service for UNIX, Windows
and the World Wide Web.  These devices deliver fast, simple, reliable, and
cost-effective access to data stored in the network.  The company pioneered the
concept of the "network appliance," an extension of the industry trend toward
dedicated, specialized products that perform a single function.  Network
Appliance filers are based on the company's innovative data access software
known as Data ONTAP and standards-compliant hardware.  More information is
