                                   THE COMPANY

        Cisco's principal executive offices are located at 255 West Tasman
Drive, San Jose, California 95134. Cisco's telephone number is (408) 526-4000.

                              PLAN OF DISTRIBUTION

        Cisco is registering all 438,280 shares (the "Shares") on behalf of
certain selling shareholders. All of the shares originally were issued by us in
connection with our acquisition of Calista, Inc. We merged with Calista, Inc.
and we are the surviving corporation. Cisco will receive no proceeds from this
offering. The Selling Shareholders named in the table below or pledgees, donees,
transferees or other successors-in-interest selling shares received from a named
selling shareholder as a gift, partnership distribution or other
non-sale-related transfer after the date of this prospectus (collectively, the
"Selling Shareholders") may sell the shares from time to time. The Selling
Shareholders will act independently of Cisco in making decisions with respect to
the timing, manner and size of each sale. The sales may be made on one or more
exchanges or in the over-the-counter market or otherwise, at prices and at terms
then prevailing or at prices related to the then current market price, or in
negotiated transactions. The Selling Shareholders may effect such transactions
by selling the shares to or through broker-dealers. The shares may be sold by
one or more of, or a combination of, the following:

        o   a block trade in which the broker-dealer so engaged will attempt to
            sell the shares as agent but may position and resell a portion of
            the block as principal to facilitate the transaction,

        o   purchases by a broker-dealer as principal and resale by such
            broker-dealer for its account pursuant to this prospectus,

        o   an exchange distribution in accordance with the rules of such
            exchange,

        o   ordinary brokerage transactions and transactions in which the broker
            solicits purchasers, and

        o   in privately negotiated transactions.

        To the extent required, this prospectus may be amended or supplemented
from time to time to describe a specific plan of distribution. In effecting
sales, broker-dealers engaged by the Selling Shareholders may arrange for other
broker-dealers to participate in the resales.

        The Selling Shareholders may enter into hedging transactions with
broker-dealers in connection with distributions of the shares or otherwise. In
such transactions, broker-dealers may engage in short sales of the shares in the
course of hedging the positions they assume with Selling Shareholders. The
Selling Shareholders also may sell shares short and redeliver the shares to
close out such short positions. The Selling Shareholders may enter into option
or other transactions with broker-dealers which require the delivery to the
broker-dealer of the shares. The broker-dealer may then resell or otherwise
transfer such shares pursuant to this prospectus. The Selling Shareholders also
may loan or pledge the shares to a broker-dealer. The broker-dealer may sell the
shares so loaned, or upon a default the broker-dealer may sell the pledged
shares pursuant to this prospectus.

        Broker-dealers or agents may receive compensation in the form of
commissions, discounts or concessions from Selling Shareholders. Broker-dealers
or agents may also receive compensation from the purchasers of the shares for
whom they act as agents or to whom they sell as principals, or both.
Compensation as to a particular broker-dealer might be in excess of customary
commissions and will be in amounts to be negotiated in connection with the sale.
Broker-dealers or agents and any other participating broker-dealers or the
Selling Shareholders may be deemed to be "underwriters" within the meaning of
Section 2(11) of the Securities Act in connection with sales of the shares.
Accordingly, any such commission, discount or concession received by them and
any profit on the resale of the shares purchased by them may be deemed to be
underwriting discounts or commissions under the Securities Act. Because Selling
Shareholders may be deemed to be "underwriters" within the meaning of Section
2(11) of the Securities Act, the Selling Shareholders will be subject to the
prospectus delivery requirements of the Securities Act. In addition, any
securities covered by this prospectus which qualify for sale pursuant to Rule
144 promulgated under the Securities Act may be sold under Rule 144 rather than
pursuant to this prospectus. The Selling Shareholders have advised Cisco that
they have not entered into any agreements, understandings or


                                       3
<PAGE>   5

arrangements with any underwriters or broker-dealers regarding the sale of their
securities. There is no underwriter or coordinating broker acting in connection
with the proposed sale of shares by Selling Shareholders.

        The shares will be sold only through registered or licensed brokers or
dealers if required under applicable state securities laws. In addition, in
certain states the shares may not be sold unless they have been registered or
qualified for sale in the applicable state or an exemption from the registration
or qualification requirement is available and is complied with.

        Under applicable rules and regulations under the Exchange Act, any
person engaged in the distribution of the shares may not simultaneously engage
in market making activities with respect to our common stock for a period of two
business days prior to the commencement of such distribution. In addition, each
Selling Shareholder will be subject to applicable provisions of the Exchange Act
and the associated rules and regulations under the Exchange Act, including
Regulation M, which provisions may limit the timing of purchases and sales of
shares of our common stock by the Selling Shareholders. Cisco will make copies
of this prospectus available to the Selling Shareholders and has informed them
of the need for delivery of copies of this prospectus to purchasers at or prior
to the time of any sale of the shares.

        Cisco will file a supplement to this prospectus, if required, pursuant
to Rule 424(b) under the Securities Act upon being notified by a Selling
Shareholder that any material arrangement has been entered into with a
broker-dealer for the sale of shares through a block trade, special offering,
exchange distribution or secondary distribution or a purchase by a broker or
dealer. Such supplement will disclose:

        o   the name of each such Selling Shareholder and of the participating
            broker-dealer(s),

        o   the number of shares involved,

        o   the price at which such shares were sold,

        o   the commissions paid or discounts or concessions allowed to such
            broker-dealer(s), where applicable,

        o   that such broker-dealer(s) did not conduct any investigation to
            verify the information set out or incorporated by reference in this
            prospectus, and

        o   other facts material to the transaction.

        In addition, upon being notified by a Selling Shareholder that a donee
or pledgee intends to sell more than 500 shares, Cisco will file a supplement to
this prospectus.

        Cisco will bear all costs, expenses and fees in connection with the
registration of the shares. The Selling Shareholders will bear all commissions
and discounts, if any, attributable to the sales of the shares. The Selling
Shareholders may agree to indemnify any broker-dealer or agent that participates
in transactions involving sales of the shares against certain liabilities,
including liabilities arising under the Securities Act. The Selling Shareholders
have agreed to indemnify certain persons, including broker-dealers and agents,
against certain liabilities in connection with the offering of the shares,
including liabilities arising under the Securities Act.

                              SELLING SHAREHOLDERS

        The following table sets forth the number of shares owned by each of the
Selling Shareholders. None of the Selling Shareholders has had a material
relationship with Cisco within the past three years other than as a result of
the ownership of the shares or other securities of Cisco. No estimate can be
given as to the amount of shares that will be held by the Selling Shareholders
after completion of this offering because the Selling Shareholders may offer all
or some of the shares and because there currently are no agreements,
arrangements or understandings with respect to the sale of any of the shares.
The shares offered by this prospectus may be offered from time to time by the
Selling Shareholders named below.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

        Section 317 of the California Corporations Code authorizes a court to
award, or a corporation's Board of Directors to grant, indemnity to directors
and officers in terms sufficiently broad to permit indemnification, including
reimbursement of expenses incurred, under certain circumstances for liabilities
arising under the Securities Act. Cisco's Restated Articles of Incorporation, as
amended, and Amended Bylaws provide for indemnification of its directors,
officers, employees and other agents to the maximum extent permitted by the
California Corporations Code. In addition, Cisco has entered into
indemnification agreements with each of its directors and officers.

ITEM 17.  UNDERTAKINGS

The undersigned registrant hereby undertakes:

        (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement: (i) to include any
prospectus required by Section 10(a)(3) of the Securities Act; (ii) to reflect
in the prospectus any facts or events arising after the effective date of the
registration statement, or the most recent post-effective amendment thereof,
which, individually or in the aggregate, represent a fundamental change in the
information set forth in the registration statement; and (iii) to include any
material information with respect to the plan of distribution not previously
disclosed in the Registration Statement or any material change to such
information in the registration statement.

        (2) That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

        (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.


                                      II-1
<PAGE>   9

        Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions or otherwise, the registrant has
been advised that in the opinion of the SEC such indemnification is against
public policy as expressed in the Securities Act and therefore is unenforceable.
In the event that a claim for indemnification against such liabilities, other
than the payment by the registrant of expenses incurred or paid by a director,
officer or controlling person of the registrant in the successful defense of any
action, suit or proceeding is asserted by such director, officer or controlling
person in connection with the securities being registered, the registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

        The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act, and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act, that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

                 AGREEMENT AND PLAN OF MERGER AND REORGANIZATION


               This AGREEMENT AND PLAN OF MERGER AND REORGANIZATION (this
"Agreement") is made and entered into as of August 12, 1999, by and between
Cisco Systems, Inc., a California corporation ("Acquiror"), and Calista, Inc., a
Delaware corporation ("Target").

                                    RECITALS

               A. The Boards of Directors of Target and Acquiror believe it is
advisable and in the best interests of their respective companies and the
stockholders of their respective companies that Target merge with and into
Acquiror (the "Merger") and, in furtherance thereof, have unanimously approved
the Merger.

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

               C. Target and Acquiror desire to make certain representations,
warranties, covenants 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 Sections 368(a) of the Code.

               E. Concurrently with the execution of this Agreement and as an
inducement to Acquiror and Target to enter into this Agreement a certain
stockholder of Target has on the date hereof entered into a stockholder
agreement (the "Stockholder Agreement") to, among other things, vote the shares
of Target Common Stock owned by such person to approve the Merger.

               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
Certificate of Merger attached hereto as Exhibit A-1 (the "Certificate of
Merger"), the Agreement of Merger attached hereto as Exhibit A-2 (the "Agreement
of Merger") and the applicable provisions of the Delaware General Corporation
Law ("Delaware Law") and 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
(the "Merger"). Acquiror as the surviving corporation after the Merger is
hereinafter sometimes referred to as the "Surviving Corporation."



<PAGE>   6

               1.2  CLOSING; EFFECTIVE TIME. The closing of the transactions
contemplated hereby (the "Closing") shall take place as soon as practicable (and
in any event not later than five business days) 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 the offices of Brobeck Hale and Dorr, Hasilwood House, 60 Bishopsgate,
London, EC2N 4AJ, England, or at such other location as the parties hereto
agree. At the Closing, the parties hereto shall cause the Merger to be
consummated by filing the Certificate of Merger with the Secretary of State of
Delaware, in accordance with the relevant provisions of Delaware Law, and the
Agreement of Merger, together with the required officer's certificates, with the
Secretary of State of California, in accordance with the relevant provisions of
California Law (the time of such California filing, or such later time as may be
agreed to by the parties and set forth in the Agreement of Merger, 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 Certificate of Merger,
the Agreement of Merger and the applicable provisions of California Law and
Delaware 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 and Acquiror shall vest in the Surviving Corporation, and
all debts, liabilities and duties of Target and Acquiror shall become the debts,
liabilities and duties of the Surviving Corporation.

               1.4  ARTICLES OF INCORPORATION; BYLAWS.

                      (a) At the Effective Time, the Articles of Incorporation
of Acquiror, as in effect immediately prior to the Effective Time, shall be
Articles of Incorporation of the Surviving Corporation.

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

               1.5  DIRECTORS AND OFFICERS. At the Effective Time, the
directors of Acquiror, as in effect immediately prior to the Effective Time,
shall be the directors of the Surviving Corporation, until their respective
successors are duly elected or appointed and qualified. The officers of
Acquiror, as in effect immediately prior to the Effective Time, shall be the
officers of the Surviving Corporation, until their respective successors are
duly elected or appointed and qualified.

               1.6  EFFECT ON CAPITAL STOCK. By virtue of the Merger and
without any action on the part of Acquiror, Target or the holders of any of
Target's securities:

                      (a) Conversion of Target Capital Stock. Notwithstanding
any provision of this Agreement to the contrary, the maximum number of shares of
Acquiror Common Stock to be issued (including Acquiror Common Stock to be
reserved for issuance upon exercise of options to purchase shares of Target
Common Stock ("Target Options") assumed by Acquiror) in exchange for the
acquisition by Acquiror of all outstanding Target Capital Stock and all
unexpired and unexercised outstanding options to acquire Target Capital Stock
shall be equal to that number of shares determined by dividing $55,000,000 (the


                                       2
<PAGE>   7

"Valuation") by the average of the closing bid prices for a share of Acquiror
Common Stock as quoted on the Nasdaq National Market for the ten (10) trading
days immediately preceding and ending on the trading day that is three (3)
calendar days prior to the Closing Date (the "Acquiror Stock Price") (the number
of shares determined above being referred to herein as the "Total Acquiror
Shares"), reduced as a result of any Dissenting Shares (as defined below). No
other adjustment shall be made in the number of shares of Acquiror Common Stock
issued in the Merger as a result of (x) any increase or decrease in the market
price of Acquiror Common Stock prior to the Effective Time not otherwise
required by the immediately preceding sentence, or (y) any cash proceeds
received by Target from the date hereof to the Closing Date pursuant to the
exercise of currently outstanding options to acquire Target Capital Stock. All
references in this Agreement to Acquiror Common Stock to be issued pursuant to
the Merger shall be deemed to include the corresponding rights to purchase
shares of Acquiror Series A Junior Participating Preferred Stock, no par value,
pursuant to the Acquiror Rights Agreement dated as of June 10, 1998 between
Acquiror and BankBoston, N.A., except where the context otherwise requires.
Subject to the terms and conditions of this Agreement, the Certificate of Merger
and the Agreement of Merger as of the Effective Time, by virtue of the Merger
and without any action on the part of the holder of any shares of Target Capital
Stock:

                             (A) At the Effective Time, each share of Target
               Common Stock issued and outstanding immediately prior to the
               Effective Time (other than shares, if any, held by persons who
               have not voted such shares for approval of the Merger and with
               respect to which such persons shall have perfected dissenters'
               rights in accordance with Delaware Law ("Dissenting Shares"))
               shall be converted into and exchanged for the right to receive
               such number of shares of Acquiror Common Stock as shall be
               determined in accordance with item (i) of Exhibit B hereof (the
               "Exchange Ratio"). Each share of Target Common Stock issued and
               outstanding immediately prior to the Effective Time that is
               restricted or not fully vested shall upon such conversion and
               exchange have the same restrictions or vesting arrangements
               applicable to such shares prior to the conversion.

                             (B) At the Effective Time, each Target Option
               granted and outstanding immediately prior to the Effective Time
               shall be assumed by Acquiror in accordance with Section 5.9 and
               thereafter shall constitute the right to receive options to
               purchase such number of shares of Acquiror Common Stock as shall
               be determined in accordance with item (ii) of Exhibit B hereof.

                      (b) Cancellation of Target Capital Stock Owned by Acquiror
or Target. At the Effective Time, all shares of Target Capital Stock that are
owned by Target as treasury stock, and each share of Target Capital Stock owned
by Acquiror or any direct or indirect wholly owned subsidiary of Acquiror or of
Target immediately prior to the Effective Time shall be canceled and
extinguished without any conversion thereof.

                      (c) Target Stock Option Plan. At the Effective Time,
Target's 1999 Employee Stock Option Plan (the "Target Stock Option Plan"), and
all options to purchase Target Common Stock then outstanding under the Target
Stock Option Plan shall be assumed by Acquiror in accordance with Section 5.9.


                                       3
<PAGE>   8

                      (d) Adjustments to Exchange Ratio. The Exchange Ratio
shall be adjusted to reflect fully the effect of any stock split, reverse 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 occurring after the date hereof and prior to the Effective
Time.

                      (e) 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 Acquiror Stock Price.

                      (f) Dissenters' Rights. Any 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 Delaware Law. Target agrees that, except
with the prior written consent of Acquiror (such consent not to be unreasonably
withheld or delayed), or as required under Delaware 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 Stockholder")
who, pursuant to the provisions of Delaware Law, becomes entitled to payment of
the fair value 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 stockholder of certificate or
certificates representing shares of Target Capital Stock, the number of shares
of Acquiror Common Stock to which such stockholder would otherwise be entitled
under this Section 1.6, the Certificate of Merger and the Agreement of Merger
less the number of shares allocable to such stockholder that have been deposited
in the Escrow Fund (as defined below) in respect of such shares of Acquiror
Common Stock pursuant to Section 1.7(c) and Article VIII hereof.

               1.7  SURRENDER OF CERTIFICATES.

                      (a) Exchange Agent. BankBoston, N.A. 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) the shares of Acquiror Common Stock
issuable pursuant to Section 1.6(a) (provided that delivery of any shares that
are subject to vesting shall be in book entry form only until such vesting
restrictions have lapsed) in exchange for shares of Target Capital Stock
outstanding immediately prior to the Effective Time less (in the case of the
holders of Target Capital Stock other than Acquiror) the number of shares of
Acquiror Common Stock to be deposited into an escrow fund (the "Escrow Fund")
pursuant to the requirements of Article VIII and (ii) cash in an amount
sufficient to permit payment of cash in lieu of fractional shares pursuant to
Section 1.6(e); it being understood that, notwithstanding anything herein to the
contrary, the Escrow Shares (as


                                       4
<PAGE>   9

defined below) shall consist solely of shares of Acquiror Common Stock issuable
pursuant to Section 1.6(a) to holders of Target Capital Stock other than
Acquiror, and shall be so withheld on a pro rata basis for deposit in the Escrow
Fund only from shares of Acquiror Common Stock issuable as aforesaid to such
holders other than Acquiror until expiration of the Escrow Fund as set forth in
Article VIII hereof.

                      (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 1.6,
(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 (or book entries in the case of shares that have not yet
vested) 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 (or a book entry in
the case of shares that have not yet vested in full) representing the number of
whole shares of Acquiror Common Stock less the number of shares of Acquiror
Common Stock to be deposited in the Escrow Fund on such holder's behalf pursuant
to Article VIII hereof and payment in lieu of fractional shares which such
holder has the right to receive pursuant to Section 1.6, 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 1.6. As soon as practicable after the Effective Time,
and subject to and in accordance with the provisions of Article VIII hereof,
Acquiror shall cause to be distributed to the Escrow Agent (as defined in
Article VIII hereof) a certificate or certificates representing ten percent
(10%) of the number of shares determined by dividing the Valuation by the
Acquiror Stock Price (the "Escrow Shares"), which shall be registered and held
in the name of the Escrow Agent as nominee for the holders of Certificates
cancelled pursuant to this Section 1.7. The Escrow Shares shall be, to the
extent possible, vested shares not subject to any repurchase rights, shall be
beneficially owned by such holders and shall be held in escrow and shall be
available to compensate Acquiror for certain damages as provided in Article
VIII. To the extent not used for such purposes, such shares shall be released,
all as provided in Article VIII hereof.

                      (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


                                       5
<PAGE>   10

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 1.7(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 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 1.7, 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 1.7
shall also apply to Dissenting Shares that lose their status as such, except
that the obligations of Acquiror under this Section 1.7 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 and cash in lieu of any fractional shares to which such holder is entitled
pursuant to Section 1.6 hereof.

               1.8  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.

               1.9  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 1.6; 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.


                                       6
<PAGE>   11

               1.10  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.

               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
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

               Any reference to any event, change, condition or effect being
"material" with respect to any entity or group of entities means any event,
change, condition or effect which (i) is material to the condition (financial or
otherwise), properties, assets (including intangible assets), liabilities,
business, operations or results of operations of such entity or group of
entities, taken as a whole or (ii) would prevent or materially alter or delay
any of the transactions contemplated by this Agreement. Any reference to a
"Material Adverse Effect" with respect to any entity or group of entities means
any event, change or effect that (x) is materially adverse to the condition
(financial or otherwise), properties, assets (including intangible assets),
liabilities, business, operations or results of operations of such entity and
its subsidiaries, taken as a whole or (y) would prevent or materially alter or
delay any of the transactions contemplated by this Agreement.

               Any reference to a party's "knowledge" means (i) with respect to
any natural person, the actual knowledge, after reasonable inquiry, of such
person, or (ii) with respect to any corporation or entity, the actual knowledge
of such party's officers and directors provided that such persons shall have
made due and diligent inquiry of those employees of such party whom such
officers and directors reasonably believe would have actual knowledge of the
matters represented.

               Except as disclosed in the Disclosure Schedule, attached as an
exhibit to this Agreement and delivered by Target to Acquiror simultaneously
with the execution and delivery of this Agreement, Target represents and
warrants to Acquiror as follows. Disclosures made under one section heading of
the Disclosure Schedule may be deemed as disclosure relating to one or more
other sections of this Agreement to the extent such disclosure would be
appropriate in such other section provided that such disclosure is either
cross-referenced or the substance of such disclosure is reasonably evident from
the context.

               2.1  ORGANIZATION, STANDING AND POWER. Each of Target and its
subsidiaries is a corporation duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization. Each of Target and
its subsidiaries has the corporate power to own its properties and to carry on
its business as now being conducted and as currently proposed to be


                                       7
<PAGE>   12

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 the Certificate of Incorporation and Bylaws or other charter
documents, as applicable, of Target and each of its subsidiaries, each as
amended to date, to Acquiror. Neither Target nor any of its subsidiaries is in
violation of any of the provisions of its Certificate of Incorporation and
Bylaws or equivalent organizational documents. Except for the entities
identified in Schedule 2.1 of the Disclosure Schedule, 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.
Target is the owner of all outstanding shares of capital stock of each of the
entities set forth on Schedule 2.1 (each a "subsidiary" and collectively the
"subsidiaries") and all such shares are duly authorized, validly issued, fully
paid and nonassessable. All of the outstanding shares of capital stock of each
such subsidiary are owned by Target 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
obligating Target or any such subsidiary to issue, transfer, sell, purchase,
redeem or otherwise acquire any such securities.

               2.2  CAPITALIZATION; TITLE TO THE SHARES. The authorized capital
stock of Target consists of 16,000,000 shares of Common Stock, of which there
were issued and outstanding as of the close of business on the date hereof
8,140,000 shares of Common Stock. Except as set forth on Schedule 2.2, 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, other than pursuant to the exercise of options outstanding as of the
date hereof under the Target Stock Option Plan. Attached to or as set forth in
Schedule 2.2 to the Disclosure Schedule is a true and correct list of Target's
shareholders and any persons with rights to acquire Target securities from
Target, which list will be promptly updated from time to time prior to Closing
to reflect any changes thereto (which changes are in any event subject to the
restrictions imposed under Section 4.2 below). 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, and are not subject to preemptive
rights or rights of first refusal created by statute, the Certificate of
Incorporation or Bylaws of Target or any agreement to which Target is a party or
by which it is bound. Target has reserved 6,400,000 shares of Common Stock for
issuance to employees and consultants pursuant to the Target Stock Option Plan,
of which 130,000 shares have been issued pursuant to option exercises, 6,070,000

under treasury regulations promulgated under section 414(o) of the Code, any of
which includes Target. Schedule 2.14 attached hereto expressly identifies which
of Target's Employee Plans, individually or collectively, constitute an
"employee welfare benefit plan" as defined in Section 3(1) of ERISA
(collectively, the "Welfare Benefit Plans").

                      (b) None of the Employee Benefit Plans is an "employee
pension benefit plan," as defined in Section 3(2) of ERISA and neither Target
nor any ERISA Affiliate has ever sponsored, maintained or contributed to, or
ever been obligated to contribute to, an "employee pension benefit plan."

                      (c) None of the Employee Benefit Plans is a pension
benefit plan or other plan of deferred compensation that provides "relevant
benefits" within the meaning of Section 612 of the Income and Corporation Tax
Act of 1988 (as applicable in England and Wales.) and neither Target nor any
ERISA Affiliate has ever sponsored, maintained or contributed to, or ever been
obligated to contribute to, such a plan.

                      (d) Target does not maintain or contribute to any Employee
Plan that provides health benefits to an employee after the employee's

                      (e) Each Employee Plan materially complies by its terms

or governmental rules or regulations applicable to the Plan, including but not
limited to ERISA and the Code.

in section 4980B(f)(3) of the Code) occurring prior to and including the Closing
Date, and no tax payable on account of Section 4980B of the Code has been
incurred with respect to any current or former employee of Target.

                      (g) Target is not a party to any contract, instrument,
agreement or arrangement with a "disqualified individual" (as defined in Section
280G(c) of the Code) that could result in a disallowance of the deduction for
any "excess parachute payment" (as defined in Section 280G(b)(i) of the Code) or
subject any such disqualified individual to the excise tax imposed under Section
4999 of the Code.

                      (h) All reports, forms and other documents required to be
filed with any government entity with respect to any Plan (including without

have been timely filed and are accurate.

                      (i) All contributions for all periods ending prior to the

                      (j) All insurance premiums have been paid in full, subject
only to normal retrospective adjustments in the ordinary course, with regard to
the Employee Plans for plan years ending on or before the Closing Date.

                      (k) With respect to each Welfare Benefit Plan:

                             (i) no action or claims (other than routine claims
        for benefits made in the ordinary course of Employee Plan administration
        for which Employee Plan administrative review procedures have not been
        exhausted) are pending, threatened or imminent against or with respect
        to the Employee Plan, any employer who is participating (or who has
        participated) in any Plan or any fiduciary (as defined in Section 3(21)
        of ERISA), of the Employee Plan;

                             (ii) neither Target nor any fiduciary has any
        knowledge of any facts which could give rise to any such action or
        claim; and

                             (iii) the governing instruments of the plan provide
        that it may be amended or terminated at any time and all benefits
        payable to current, terminated employees or any beneficiary may be
        amended or terminated by Target or an ERISA Affiliate at any time
        without liability.

                      (l) True, correct and complete copies of all documents
creating or evidencing any Plan listed in Schedule 2.14 have been delivered to
Purchaser, and true, correct and complete copies of all reports, forms and other
documents required to be filed with any governmental entity (including, without
limitation, summary plan descriptions, Forms 5500 and summary annual reports for
all plans subject to ERISA) have been delivered to Purchaser. There are no
negotiations, demands or proposals which are pending or have been made which
concern matters now covered, or that would be covered, by the type of agreements
listed in Schedule 2.14.

                      (m) All expenses and liabilities relating to all of the
Employee Plans described in Schedule 2.14 have been, and will on the Closing
Date be, fully and properly accrued on Target's books and records and disclosed
in accordance with generally accepted accounting principles and in Employee
Plans' financial statements.

               2.15  CERTAIN AGREEMENTS AFFECTED BY THE MERGER. Neither the
execution and delivery of this Agreement nor the consummation of the
transactions contemplated hereby will (i) result in any payment (including,
without limitation, severance, unemployment compensation, contractual or
statutory redundancy pay, golden parachute, liquidated damages, damages for
breach of contract or wrongful dismissal, compensation in respect of unfair
dismissal, bonus or otherwise) becoming due to any present or former director or
employee or consultant of Target or any of its subsidiaries, (ii) materially
increase or create any power to augment or augment any benefits otherwise
payable by Target or any of its subsidiaries in respect of any present or former
director or employee of Target of any of its subsidiaries or (iii) result in the
acceleration of the time of payment or vesting of any such benefits. No payment
which will or may be made by Target or any of its subsidiaries to any employee
will be characterized as an "excess parachute payment" within the meaning of
Section 280G(b)(1) of the Code.

connection with employment, terms and conditions of employment, wages, hours and
occupational safety and health and employment practices, in connection with all
present and former directors, employees and consultants of Target and any of its
subsidiaries.

                      (b) Each of Target and its subsidiaries has, in relation
to all present and former directors, employees and consultants of Target and any
of its subsidiaries, withheld all amounts required by law or by agreement to be
withheld from the wages, salaries, and other payments to employees; and has, in
relation to such persons, discharged its obligations in full and is not liable
for any arrears in respect of wages, salaries, fees, commission, bonus, overtime
pay, holiday pay, sick pay, employer pension contribution (and employee pension
contribution where relevant) and any other benefits and emoluments or any taxes
or national insurance contributions and is not liable in respect of any penalty
for failure to comply in any material respect with any of the foregoing.

                      (c) Neither Target nor any of its subsidiaries is liable
for any payment to any trust or other fund or to any governmental or
administrative authority, with respect to unemployment compensation benefits,
social security or other benefits or obligations for employees (other than
routine payments to be made in the normal course of business and consistent with
past practice).

                      (d) There are no pending claims against Target under any
workers compensation plan or policy or for long term disability.

                      (e) There are no controversies or disputes (whether
industrial, trade or otherwise) pending or, to the knowledge of Target,
threatened, between Target or any of its subsidiaries, on the one hand, and any
of their respective present or former directors, employees, consultants and/or
other employees' representatives on the other hand, which controversies have or
could reasonably be expected to result in an action, suit, proceeding, claim,
arbitration or investigation before any agency, court or tribunal in the United
States or in any other jurisdiction.

                      (f) Neither Target nor any of its subsidiaries is a party
to any collective bargaining agreement or other labor union contract or any form
of agreement or arrangement (whether oral or in writing or existing by reason of
custom and practice and whether or not legally binding) with any labor union or
other employees' representatives or organization concerning or affecting
Target's or any of its subsidiaries' employees nor does Target know of any
activities or proceedings of any labor union to organize any such employees.
Further, neither Target nor any of its subsidiaries, so far as Target is aware,
has done any act which might be reasonably construed as recognition and there
has been no request for recognition from any labor union and no such request is
pending.

                      (g) To Target's knowledge, no employees of Target or any
of its subsidiaries are in violation of any term of any employment contract,
patent disclosure


                                       20

agreement, noncompetition agreement, confidentiality agreement, or any
restrictive covenant to a former employer relating to the right of any such
employee to be employed by Target or any of its subsidiaries because of the
nature of the business conducted or presently proposed to be conducted by Target
or to the use of trade secrets or proprietary information of others.

                      (h) No key employees or officers of Target or any of its
subsidiaries have given notice to Target, nor is Target otherwise aware, that
any such key employee or officer intends to terminate his or her employment with
Target or any of its subsidiaries.

                      (i) Neither Target nor any of its subsidiaries has either
given notice of any redundancies to any statutory or regulatory body nor started
consultations with any labor union or employees' representatives within the
preceding period of one year in relation to any of its employees. To Target's
knowledge no circumstances have arisen under which Target or any of its
subsidiaries is reasonably likely to be required to pay damages for wrongful
dismissal or breach of contract, to make any contractual or statutory redundancy
payment or make or pay any compensation in respect of unfair dismissal, to make
any other payment under any employment law or to reinstate or re-engage any
former employee. To Target's knowledge no circumstances have arisen or exist
under which Target or any of its subsidiaries may be required to pay damages or
compensation, or suffer any penalty or be required to take corrective action or
be subject to any form of sanction under the following legislation (as
applicable in England and Wales): Employment Rights Act of 1996, the Trade Union
and Labour Relations (Consolidation) Act 1992, the Transfer of Undertakings
(Protection of Employment) Regulations 1981, the Sex Discrimination Act 1975,
the Equal Pay Act 1976, the Treaty of Rome or any Directive or recommendation
made pursuant to it, the Race Relations Act 1976, the Disability Discrimination
Act 1995, the National Minimum Wage Act 1998, the Data Protection Act 1998, the
Public Interest Disclosure Act 1998, the Working Time Regulations 1998, the
Acquired Rights Directive or any other employment law. To Target's knowledge, no
inquiries or investigations exist, are pending or threatened against Target or
any of its subsidiaries by the U.K. Equal Opportunities Commission or the U.K.
Commission for Racial Equality or other applicable authorities.

                      (j) There are no existing service or other agreements or
contracts between Target or its subsidiaries and any of its directors or
employees or consultants which cannot be lawfully terminated by three calendar
months' notice or less without giving rise to any claim for damages or
compensation other than a statutory redundancy payment.

                      (k) Neither Target nor any of its subsidiaries is involved
in negotiations (whether with employees or consultants or any labor unions or
other employees' representatives) to vary the terms and conditions of employment
or engagement of any of its employees, directors or consultants in any material
respect nor has Target made any representations, promises, offers or proposals
to any of its employees, directors or consultants or to any labor union or other
employees' representatives concerning or affecting the terms and conditions of
employment or engagement of any of its employees, directors or consultants.

                      (l) Neither Target nor any subsidiary has any continuing
obligation for health, life, medical insurance or other similar fringe benefits
or for pensions or any other form of payment to any former employee of Target or

or its subsidiaries' employees or ex-employees.

                      (n) Target has provided to Acquiror a true, correct and
complete list of current payroll of Target and its subsidiaries, including job

1998.

               2.17  INTERESTED PARTY TRANSACTIONS. Except as set forth in
Schedule 2.17 of the Disclosure Schedule, neither Target nor any of its
subsidiaries is indebted to any director, officer, employee or agent of Target
or any such subsidiary (except for amounts due as normal salaries and bonuses
and in reimbursement of ordinary expenses), and no such person is indebted to
Target or any such subsidiary.

               2.18  INSURANCE. Target and each of its subsidiaries have
policies of insurance and bonds of the type and in amounts customarily carried
by persons conducting businesses or owning assets similar to those of Target and
its subsidiaries. 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 to date
under all such policies and bonds have been paid and Target and its subsidiaries
are otherwise in compliance in all material respects 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.

               2.19  COMPLIANCE WITH LAWS. Each of Target and its subsidiaries

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.

               2.20  MINUTE BOOKS. The minute books of Target and its
subsidiaries made available to Acquiror contain a complete and accurate summary
in all material respects of all meetings of directors and shareholders or

available true and complete copies of each document which has been requested by
Acquiror or its counsel in connection with their legal and accounting review of
Target and its subsidiaries.

<PAGE>   27

               2.22  BROKERS' AND FINDERS' FEES. Target has not incurred, nor
will it incur, directly or indirectly, any liability for brokerage or finders'
fees or agents' commissions or investment bankers' fees or any similar charges

               2.23  VOTE REQUIRED. The affirmative vote of the holders of at
least a majority of Target Common Stock outstanding on the record date set for

Target's capital stock necessary to approve this Agreement and the transactions

               2.24  BOARD APPROVAL. The Board of Directors of Target has
unanimously (i) approved this Agreement, (ii) determined that the transactions

of Target and on terms that are fair to such stockholders and (iii) recommended
that the stockholders of Target approve this Agreement.

               2.25  ACCOUNTS RECEIVABLE. Subject to any reserves set forth in
the Financial Statements, the accounts receivable shown on the Financial

sales and other charges, and are not subject to discount except for normal cash

               2.26  CUSTOMERS AND SUPPLIERS. No customer which individually
accounted for more than 15% of Target's gross revenues during the 12-month
period preceding the date hereof, and no material supplier of Target or any of
its subsidiaries, has canceled or otherwise terminated, or made any written
threat to Target or any such subsidiary to cancel or otherwise terminate its
relationship with Target or any such subsidiary, or has decreased materially its
services or supplies to Target or any such subsidiary in the case of any such
supplier, or its usage of the services or products of Target or any such
subsidiary in the case of such customer, and to Target's knowledge, no such
supplier or customer intends to cancel or otherwise terminate its relationship
with Target or any such subsidiary or to decrease materially its services or
supplies to Target or any such subsidiary or its usage of the services or
products of Target or any such subsidiary, as the case may be. Neither Target
nor any of its subsidiaries has knowingly breached, so as to provide a benefit
to Target or any such subsidiary that was not intended by the parties, any
agreement with, or engaged in any fraudulent conduct with respect to, any
customer or supplier of Target or any such subsidiary.

               2.27  MATERIAL CONTRACTS. Except for the contracts and agreements
listed in Schedule 2.27 to the Disclosure Schedule (collectively, the "Material
Contracts"), neither Target nor any of its subsidiaries is a party to or bound
by any material contract, including without limitation:

                      (a) any distributor, agency or manufacturer's
representative contract;

                      (b) any continuing contract for the purchase and sale of
materials, supplies, equipment or services (including advertising), involving in
the case of any such contract more than $20,000 over the life of the contract;

                      (c) any contract that expires or may be renewed at the
option of any person other than Target so as to expire more than one year after
the date of this Agreement;


                                       23
<PAGE>   28

                      (d) any trust indenture, mortgage, promissory note, loan
agreement or other contract for the borrowing of money, any currency exchange,
commodities or other hedging arrangement or any leasing transaction of the type
required to be capitalized in accordance with generally accepted accounting
principles;

                      (e) any contract for capital expenditures in excess of
$40,000 in the aggregate;

                      (f) any contract limiting the freedom of Target or any of
its subsidiaries to engage in any line of business or to compete with any other
Person as that term is defined in the U.S. Securities Exchange Act of 1934, as
amended, or, other than those entered into in the ordinary course of business,
any confidentiality, secrecy or non-disclosure contract;

                      (g) any contract pursuant to which Target is a lessor of
any machinery, equipment, motor vehicles, office furniture, fixtures or other
personal property, involving in the case of any such contract more than $20,000
over the life of the contract;

                      (h) any contract with any affiliate of Target or any of
its subsidiaries; or

                      (i) any agreement of guarantee, support, indemnification,
assumption or endorsement of, or any similar commitment with respect to, the
obligations, liabilities (whether accrued, absolute, contingent or otherwise) or
indebtedness of any other Person, except such agreements entered into in the
ordinary course of business.

               2.28  NO BREACH OF MATERIAL CONTRACTS. All Material Contracts are
in written form. Each of Target and its subsidiaries has in all material
respects performed the obligations required to be performed by it and is
entitled to all benefits under, and is not, to the knowledge of Target, alleged
to be in default in respect of any Material Contract. Each of the Material
Contracts is in full force and effect, and there exists no default or event of
default or event, occurrence, condition or act, with respect to Target or any of
its subsidiaries or, to the knowledge of Target, with respect to the other
contracting party, which, with the giving of notice, the lapse of time or the
happening of any other event or conditions, would reasonably be expected to
become a material default or event of default under any Material Contract. True,
correct and complete copies of all Material Contracts have been delivered or
made available to the Acquiror.

               2.29  THIRD PARTY CONSENTS. Schedule 2.29 of the Disclosure
Schedule lists all contracts of Target and each of its subsidiaries that would
permit the other party to the contract to terminate the contract or otherwise
would require the consent of such other party as a result of the transactions
contemplated by this Agreement (each a "Consent Contract").

               2.30  MATERIAL THIRD PARTY CONSENTS. Schedule 2.30 of the
Disclosure Schedule includes every Consent Contract which if no consent of the
other party to the contract was obtained in connection with the transactions
contemplated by this Agreement would have a Material Adverse Effect on
Acquiror's ability to operate the business of Target and its subsidiaries in the
same manner as the business was operated by Target and its subsidiaries prior to
the Closing Date.


                                       24

               2.31  EXPORT CONTROL LAWS. Target has conducted its export
transactions in all material respects in accordance with applicable provisions
of export control laws in the country of origin and the country of destination.

               2.32  PRODUCT RELEASES. Target has provided Acquiror a Schedule
of Product Releases, which Schedule is attached as Schedule 2.32 to the
Disclosure Schedule. Target has a good faith reasonable belief that it can
achieve the release of products on the schedule and is not currently aware of
any change in its circumstances or other fact that has occurred that would cause
it to believe that it will be unable to meet such release schedule.

               2.33  YEAR 2000. Except as a result of errors or "bugs"
contained in data that is generated by third parties and processed by Target's
products, none of the products sold or licensed by Target or by any of its
subsidiaries in the conduct of their respective businesses will malfunction,
will cease to function, will generate materially incorrect data or will produce
materially incorrect results and will not directly cause any of the above with
respect to the property or business of third parties using such products or
services when processing, providing or receiving (i) date-related data from,
into and between the Twentieth (20th) and Twenty-First (21st) centuries, or (ii)
date-related data in connection with any valid date in the Twentieth (20th) and
Twenty-First (21st) centuries, causing a Material Adverse Effect on Target.
Except as set forth in Schedule 2.34 of the Disclosure Schedule, neither Target
nor any subsidiary has made any representations or warranties specifically
relating to the ability of any product or service sold, licensed, rendered, or
otherwise provided by Target (or by any of its subsidiaries) in the conduct of
their respective businesses to operate without malfunction, to operate without
ceasing to function, to generate correct data or to produce correct results when
processing, providing or receiving (i) date-related data from, into and between
the Twentieth (20th) and Twenty-First (21st) centuries, and (ii) date-related
data in connection with any valid date in the Twentieth (20th) and Twenty-First
(21st) centuries.

               2.34  STATE TAKEOVER STATUTES. The Board of Directors of Target
has taken all actions so that the restrictions contained in Section 203 of the
Delaware Law applicable to a "business combination" (as defined in Section 203)
will not apply to the execution, delivery or performance of this Agreement or

duly organized, validly existing and in good standing under the laws of its
jurisdiction of organization. Acquiror has the corporate power to own its

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, when
duly executed and delivered in accordance with its terms, will constitute the
valid and binding obligation of Acquiror enforceable against Acquiror in
accordance with its terms. The execution and delivery of this Agreement 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

cancellation or acceleration of any obligation or loss of a benefit under (i)
any provision of the Articles of Incorporation or Bylaws of Acquiror, as
amended, or (ii) any material mortgage, indenture, lease, contract or other
agreement or instrument, permit, concession, franchise, license, judgment, order

Financial Statements fairly present the consolidated financial condition and
operating results of Acquiror at the dates and during the periods indicated
therein (subject, in the case of unaudited statements, to normal, recurring
year-end adjustments). Acquiror currently satisfies the requirements to use Form
S-3 for registration of Acquiror Common Stock to be issued in connection with
the Merger.

Acquiror is not required for this Agreement, the attachments hereto and thereto,
and the Merger.

               3.6  TAX MATTERS. As of the date hereof, neither Acquiror nor,
to Acquiror's knowledge, any of its affiliates has taken or agreed to take any

Section 368(a) of the Code.

this Agreement. No consent or approval of the shareholders of Acquiror is
required or necessary for Acquiror to enter into this Agreement or to consummate
the transactions contemplated hereby.

will it incur, directly or indirectly, any liability for brokerage or finders'
fees or agents' commissions or investment bankers' fees or any similar charges
in connection with this Agreement or any transaction contemplated hereby for
which the stockholders of Target may be held directly liable.

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 its commercially reasonable efforts to obtain, all
consents and approvals required to be obtained by it for the consummation of the
transactions contemplated hereby, including those required under HSR and any
foreign antitrust laws. Target shall use its commercially reasonable efforts to
obtain all necessary consents, waivers and approvals under any of its material
contracts 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 or relating to
HSR or any other antitrust or fair trade law.

                      (b) Each of Acquiror and Target shall, at Acquiror's

transactions contemplated by this Agreement under the HSR, the Sherman Act, as
amended, the Clayton Act, as amended, the Federal Trade


                                       34

Commission Act, as amended, and any other Federal, state or foreign statutes,
rules, regulations, orders or decrees that are designed to prohibit, restrict or
regulate actions having the purpose or effect of monopolization or restraint of
trade (collectively, "Antitrust Laws"). In connection therewith, if any
administrative or judicial action or proceeding is instituted (or threatened to
be instituted) challenging any transaction contemplated by this Agreement as
violative of any Antitrust Law, each of Acquiror and Target shall cooperate and,
at Acquiror's expense, use all commercially reasonable efforts vigorously to
contest and resist any such action or proceeding and to have vacated, lifted,
reversed, or overturned any decree, judgment, injunction or other order, whether
temporary, preliminary or permanent (each an "Order"), that is in effect and
that prohibits, prevents, or restricts consummation of the transactions
contemplated hereby, unless by mutual agreement Acquiror and Target decide that
litigation is not in their respective best interests. Notwithstanding the
provisions of the immediately preceding sentence, it is expressly understood and
agreed that neither Acquiror nor Target shall have any obligation to litigate or
contest any administrative or judicial action or proceeding or any Order beyond
the earlier of (i) the three-month anniversary of the date hereof or (ii) the
date of a ruling preliminarily enjoining the Merger issued by a court of
competent jurisdiction. Each of Acquiror and Target shall use all commercially
reasonable efforts to take such action as may be required to cause the
expiration of the notice periods under the HSR or other Antitrust Laws with
respect to such transactions as promptly as possible after the execution of this
Agreement.

                      (c) Notwithstanding anything to the contrary in this
Agreement, (i) Acquiror shall not be required to divest any of its businesses,
product lines or assets, or to take or agree to take any other action or agree
to any limitation that could reasonably be expected to have a Material Adverse
Effect on Acquiror or on Target after the Closing Date and (ii) Target shall not
be required to divest any of its businesses, product lines or assets, or to take
or agree to take any other action or agree to any limitation that could
reasonably be expected to have a Material Adverse Effect on Target.

               5.7  LEGAL REQUIREMENTS. Each of Acquiror and Target will, and
will cause their respective subsidiaries to, take all reasonable actions
necessary to comply in all material respects 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 by them in connection with the
taking of any action contemplated by this Agreement.

               5.8  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, at Acquiror's expense, use its reasonable 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.

               5.9  EMPLOYEE BENEFIT PLANS; ASSUMPTION OF OPTIONS. Assumption
of Options. At the Closing Date, 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 (but as modified by the Amendment)
(the "Target Options"), will be assumed by Acquiror. Schedule 5.9 to the
Disclosure Schedule 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
("Option Holder") including the number of shares of Target Common Stock subject
to each such option, the exercise or vesting schedule (but as modified by the
Amendment) (as defined below), the exercise price per share and the term of each
such option. On the Closing Date, Target shall deliver to Acquiror an updated
Schedule 5.9 hereto current as of such date. Each such option so assumed by
Acquiror under the terms of this Agreement shall continue to have, and be
subject to, the same terms and conditions set forth in the Target Stock Option
Plan and the applicable stock option agreement (as modified by the Amendment)
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 transactions
contemplated hereby will not terminate any of the outstanding options under the
Target Stock Option Plan 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 hereunder. Within 30
business days after the Effective Time, Acquiror will issue to each person who,
immediately prior to the Effective Time was a holder of an outstanding option
under the Target Stock Option Plan a document in form and substance satisfactory
to Target evidencing the foregoing assumption of such option by Acquiror.

               Assignment of Repurchase Options. All outstanding rights of
Target which it may hold immediately prior to the Effective Time to repurchase
unvested shares of Target Common Stock (the "Repurchase Options") shall be
assigned to Acquiror automatically in the Merger and shall thereafter be
exercisable by Acquiror upon the same terms and conditions in effect immediately
prior to the Effective Time, except that the shares purchasable pursuant to the
Repurchase Options and the purchase price per share shall be adjusted to reflect
the Exchange Ratio.

               5.10  ESCROW AGREEMENT. On or before the Closing Date, the
parties hereto will use their reasonable best efforts to cause the Escrow Agent
(or some other entity reasonably acceptable to the parties hereto) to execute
the Escrow Agreement contemplated by Article VIII in substantially the form
attached hereto as Exhibit C ("Escrow Agreement").

               5.11  FORM S-8. Acquiror shall file a registration statement on
Form S-8 (or any successor or other appropriate forms that Acquiror is eligible
to use) under the Securities Act


                                       36
<PAGE>   41

with respect to the shares of Acquiror Common Stock subject to options held by
Option Holders within forty five (45) days following the Closing Date.

               5.12  LISTING OF ADDITIONAL SHARES. Prior to the Effective Time,
Acquiror shall cause the shares of Acquiror Common Stock issuable to the
shareholders of Target pursuant to Sections 1.3(a), 1.3(c) and 5.9, including
shares of Acquiror Common Stock issuable upon exercise of Target Options, to be
authorized for listing on the Nasdaq National Market.

               5.13  DISCLOSURE SCHEDULE. If any action is taken by Target at
the written request, or with the express written consent, of Acquiror which
action by its execution would result in the failure by Target to satisfy the
conditions set forth in Sections 6.1 or 6.3, then Acquiror shall be deemed to
have waived such conditions.

               5.14  COMMERCIALLY REASONABLE EFFORTS AND FURTHER ASSURANCES.
Each of the parties to this Agreement shall use its commercially reasonable
efforts to effectuate the transactions contemplated hereby and to fulfill and
cause to be fulfilled the conditions to closing under this Agreement. Each party
hereto, at the reasonable request of another party hereto, shall execute and
deliver such other instruments and do and perform such other acts and things as
may be necessary or desirable for effecting completely the consummation of this
Agreement and the transactions contemplated hereby.

Directors of Acquiror and Target;

                      (b) by either Acquiror or Target, if the Closing shall not

(provided, a later date may be agreed upon in writing by the parties hereto, and
provided further that the right to terminate this Agreement under this Section
7.1(b) shall not be available to any party whose action or failure to act has
been the cause or resulted in the failure of the Merger to occur on or before
such date and such action or failure to act constitutes a breach of this
Agreement);

                      (c) by Acquiror, if (i) Target shall breach any
representation, warranty, obligation or agreement hereunder and such breach (if

Agreement as provided in Section 7.1, this Agreement shall forthwith become void

representations, warranties or covenants set forth in this Agreement; provided
that the provisions of Section 5.4 (Confidentiality), Section 7.3 (Expenses and
Termination Fees) and this Section 7.2 and of Article IX shall remain in full

accountants and legal counsel) shall be paid by the party incurring such
expense.

                      (b) In the event that this Agreement shall be terminated

                                  ARTICLE VIII

                           ESCROW AND INDEMNIFICATION

               8.1  ESCROW FUND. As soon as practicable after the Effective
Time, the Escrow Shares shall be registered in the name of, and be deposited
with, State Street Bank and Trust Company of California, N.A. (or its successor
in interest or other institution selected by Acquiror with the reasonable
consent of Target) as escrow agent (the "Escrow Agent"), such deposit (together
with interest and other income thereon) to constitute the Escrow Fund and to be
governed by the terms set forth herein and in the Escrow Agreement attached
hereto as Exhibit C. The Escrow Fund shall be available to compensate Acquiror
pursuant to the indemnification obligations of the stockholders of Target.

               8.2  INDEMNIFICATION; CAP.

                      (a) Subject to the limitations set forth in this Article
VIII, subsequent to the Closing Target will indemnify and hold harmless Acquiror
and its officers, directors, agents and employees, and each person, if any, who
controls or may control Acquiror within the meaning of the Securities Act
(hereinafter referred to individually as an "Indemnified Person" and
collectively as "Indemnified Persons") from and against any and all losses,
costs, damages, liabilities and expenses arising from claims, demands, actions,
causes of action, including, without limitation, reasonable legal fees,
(collectively, "Damages") arising out of any breach of or default in connection
with any of the representations, warranties, covenants and agreements given or
made by Target in this Agreement (excluding Section 2.29 hereto), the Disclosure
Schedules or any Exhibit to this Agreement.

                      (b) Acquiror and Target each acknowledge that such
Damages, if any, would relate to unresolved contingencies existing at the
Effective Time, which if resolved at the Effective Time would have led to a
reduction in the total consideration Acquiror would have agreed to issue in
connection with the Merger. In no event shall the aggregate liability of Target
and its stockholders exceed $13,750,000 and in no event shall the individual
liability of each of Target's stockholders exceed the amounts set forth in
Section 8.2(d) herein; provided, however, that nothing in this Agreement shall
limit the liability of any Target stockholder in connection with any breach by
such stockholder of the Stockholder Agreement or irrevocably proxy or any
willful misrepresentation or breach by Target or such stockholder of any
representation, warranty or covenant of this Agreement or any fraudulent conduct
by Target or such stockholder in connection herewith.

                      (c) For the purpose of compensating Acquiror for its
Damages pursuant to this Agreement, the Acquiror Common Stock in the Escrow Fund
shall be valued at the Acquiror Stock Price.

                      (d) (i) The Escrow Fund shall be security for part of the
        indemnity obligations hereunder. Subject to the limitations in this
        Agreement, when entitled to Damages hereunder Acquiror shall be entitled
        and obligated to seek and claim the full amount of damages from the
        Escrow Fund until exhausted; and


                                       42
<PAGE>   47

                             (ii)   thereafter from all holders of Target Common
        Stock as of the Effective Time on a pro rata and several basis (based on
        their holdings as of the Effective Time) up to an aggregate liability
        per holder of Target Common Stock of 7% of the value of Acquiror Common
        Stock received by such holders as of the Effective Time.

               8.3  DAMAGE THRESHOLD. Acquiror may not receive any shares from
the Escrow Fund unless and until an Officer's Certificate or Certificates (as
defined in Section 8.5 below) identifying Damages the aggregate amount of which
exceeds $100,000 has been delivered to the Escrow Agent as provided in Section
8.5 below and such amount is determined pursuant to this Article VIII to be
payable, in which case Acquiror shall receive shares equal to the full amount of
Damages. All Damages shall be net of any insurance proceeds actually received by
Acquiror that are attributable to such Damages.

               8.4  ESCROW PERIOD. The Escrow Period shall terminate at 11:59
p.m. California time on the one-year anniversary of the Closing Date; provided,
however, that a portion of the Escrow Fund, which is necessary to satisfy any
unsatisfied claims specified in any Officer's Certificate theretofore delivered
to the Escrow Agent prior to termination of the Escrow Period with respect to
facts and circumstances existing prior to expiration of the Escrow Period, shall
remain in the Escrow Fund until such claims have been resolved. Acquiror shall
deliver to the Escrow Agent a certificate specifying the Closing Date.

               8.5  CLAIMS UPON ESCROW FUND.

                      (a) Upon receipt by the Escrow Agent on or before the last
day of the Escrow Period of a certificate signed by any officer of Acquiror (an
"Officer's Certificate"):

                             (i) stating that, Damages exist in an aggregate
        amount greater than $100,000; and

                             (ii) specifying in reasonable detail the individual
        items of such Damages included in the amount so stated, the date each
        such item was paid, or properly accrued or arose, the nature of the
        misrepresentation, breach of warranty or claim to which such item is
        related,

the Escrow Agent shall, subject to the provisions of Section 8.6 and 8.7 below,
deliver to Acquiror out of the Escrow Fund, as promptly as practicable, Acquiror
Common Stock or other assets held in the Escrow Fund having a value equal to
such Damages.

                      (b) For the purpose of compensating Acquiror for its
Damages pursuant to this Agreement, the Acquiror Common Stock in the Escrow Fund
shall be valued at the Acquiror Stock Price.

               8.6  OBJECTIONS TO CLAIMS. At the time of delivery of any
Officer's Certificate to the Escrow Agent, a duplicate copy of such Officer's
Certificate shall be delivered to the Shareholders' Agent (defined in Section
8.8 below) and for a period of forty-five (45) days after such delivery to the
Escrow Agent of such Officer's Certificate, the Escrow Agent shall make no
delivery of cash or other property pursuant to Section 8.5 hereof unless the
Escrow Agent shall have received written authorization from the Shareholders'
Agent to make such delivery. After


                                       43
<PAGE>   48

the expiration of such forty-five (45) day period, the Escrow Agent shall make
delivery of cash or other property in the Escrow Fund in accordance with Section
8.5 hereof, provided that no such payment or delivery may be made if the
Shareholders' Agent shall object in a written statement to the claim made in the
Officer's Certificate, and such statement shall have been delivered to the
Escrow Agent and to Acquiror prior to the expiration of such forty-five (45) day
period.

               8.7  RESOLUTION OF CONFLICTS; ARBITRATION.

                      (a) In case the Shareholders' Agent shall so object in
writing to any claim or claims by Acquiror made in any Officer's Certificate,
Acquiror shall have forty-five (45) days after receipt by the Escrow Agent of an
objection by the Shareholders' Agent to respond in a written statement to the
objection of the Shareholders' Agent. If after such forty-five (45) day period
there remains a dispute as to any claims, the Shareholders' Agent and Acquiror
shall attempt in good faith for sixty (60) days to agree upon the rights of the
respective parties with respect to each of such claims. If the Shareholders'
Agent and Acquiror should so agree, a memorandum setting forth such agreement
shall be prepared and signed by both parties and shall be furnished to the
Escrow Agent. The Escrow Agent shall be entitled to rely on any such memorandum
and shall distribute the cash or other property from the Escrow Fund in
accordance with the terms thereof.

                      (b) If no such agreement can be reached after such good
faith negotiation, either Acquiror or the Shareholders' Agent may, by written
notice to the other, demand arbitration of the matter unless the amount of the
damage or loss is at issue in pending litigation with a third party, in which
event arbitration shall not be commenced until such amount is ascertained or
both parties agree to arbitration; and in either such event the matter shall be
settled by arbitration conducted by three arbitrators. Within fifteen (15) days
after such written notice is sent, Acquiror or the Shareholders' Agent shall
each select one arbitrator, and the two arbitrators so selected shall select a
third arbitrator. The decision of the arbitrators as to the validity and amount
of any claim in such Officer's Certificate and the Stockholders' Agent's written
objection shall be binding and conclusive upon the parties to this Agreement,
and notwithstanding anything in Section 8.6 hereof, the Escrow Agent shall be
entitled to act in accordance with such decision and make or withhold payments
out of the Escrow Fund in accordance therewith.

                      (c) Judgment upon any award rendered by the arbitrators
may be entered in any court having jurisdiction. Any such arbitration shall be
held in Santa Clara or San Mateo County, California under the commercial rules
then in effect of the American Arbitration Association. Each party shall bear
its own expenses (including, attorneys' fees and expenses) incurred in
connection with any such arbitration, and the fees and expenses of each
arbitrator and the administrative fee of the American Arbitration Association
shall be allocated by the arbitrator or arbitrators, as the case may be (or, if
not so allocated, shall be borne equally by Acquiror, on the one hand, and
Target, on the other hand).

               8.8  SHAREHOLDERS' AGENT.

                      (a) Mark Richer shall be constituted and appointed as
agent ("Shareholders' Agent") for and on behalf of the stockholders of Target to
give and receive notices and communications, to authorize delivery to Acquiror
of the cash or other property from the Escrow Fund in satisfaction of claims by
Acquiror, to object to such deliveries, to agree to, negotiate, enter into
settlements and compromises of, and demand arbitration and comply with orders of
courts and awards of arbitrators with respect to such claims, and to take all
actions necessary or appropriate in the judgment of the Shareholders' Agent for
the accomplishment of the foregoing. Such agency may be changed by the holders
of a majority in interest of the Escrow Fund from time to time upon not less
than ten (10) days' prior written notice to Acquiror. No bond shall be required
of the Shareholders' Agent, and the Shareholders' Agent shall receive no
compensation for his services. Notices or communications to or from the
Shareholders' Agent shall constitute notice to or from each of the Target
shareholders.

                      (b) The Shareholders' Agent shall not be liable for any
act done or omitted hereunder as Shareholders' Agent while acting in good faith
and in the exercise of reasonable judgment, and any act done or omitted pursuant
to the advice of counsel shall be conclusive evidence of such good faith. The
stockholders of Target shall severally indemnify the Shareholders' Agent and
hold him harmless against any loss, liability or expense incurred without gross
negligence or bad faith on the part of the Shareholders' Agent and arising out
of or in connection with the acceptance or administration of his duties
hereunder.

               8.9  ACTIONS OF THE SHAREHOLDERS' AGENT. A written decision,
act, consent or instruction of the Shareholders' Agent shall constitute a
decision of all stockholders of Target and shall be final, binding and
conclusive upon each stockholder of Target, and the Escrow Agent and Acquiror
may rely upon any written decision, act, consent or instruction of the
Shareholders' Agent as being the decision, act, consent or instruction of each
and every such stockholder. The Escrow Agent and Acquiror are hereby relieved
from any liability to any person for any acts done by them in accordance with
such written decision, act, consent or instruction of the Shareholders' Agent.

               8.10  THIRD-PARTY CLAIMS. In the event Acquiror becomes aware of
a third-party claim which Acquiror believes may result in a demand against the
Escrow Fund, Acquiror shall promptly notify the Shareholders' Agent of such
claim, and the Shareholders' Agent shall be entitled, at their expense, to
participate in any defense of such claim. Acquiror shall have the right in its
sole discretion to settle any such claim; provided, however, that Acquiror may
not effect the settlement of any such claim without the prior written consent of
the Shareholders' Agent, which consent shall not be unreasonably withheld. In
the event that the Shareholders' Agent has consented to any such settlement, the
Shareholders' Agent shall have no power or authority to object under Section 8.7
or any other provision of this Article VIII to the amount of any claim by
Acquiror against the Escrow Fund for indemnity with respect to such settlement.

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.

               9.4  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.

               9.5  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 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, (c) shall not be
assigned by operation of law or otherwise except as otherwise specifically
provided and except that Acquiror may assign its rights hereunder to a
wholly-owned subsidiary and (d) shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and permitted assigns.

               9.6  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.

               9.7  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.

               9.8  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.

suit or proceeding arising out of or relating to this Agreement may be
instituted in any United States Federal court or any state court located in San
Jose, California, and each party agrees not to assert, by way of motion, as a
defense or otherwise, in any such action, suit or proceeding, any claim it may
now or hereafter have that it is not subject personally to the jurisdiction of
such court, that the action, suit or proceeding is brought in an inconvenient
forum, that the venue of the action, suit or proceeding is improper or that this
Agreement or the subject matter hereof may not be enforced in or by such court.
Each party further irrevocably submits to the jurisdiction of such court in any
such action, suit or proceeding, and irrevocably agrees to be bound by any final
judgment rendered thereby in connection with this Agreement from which no appeal
has been taken or is available. Any and all service of process and any other
notice in any such action, suit or proceeding shall be effective against any
party if given personally or by registered or certified mail, postage prepaid
and return receipt requested, or by personal service on such party. Nothing
contained herein shall be deemed to affect the right of any party to serve
process in any manner permitted by law or to commence legal proceedings or
otherwise proceed against any other party in any other jurisdiction.

                        OPINION OF BROBECK HALE AND DORR

               Re:    Cisco Systems, Inc. Registration Statement on Form S-3 for
                      Resale of 438,280 Shares of Common Stock

Ladies and Gentlemen:

               We have acted as counsel to Cisco Systems, Inc., a California
corporation (the "Company"), in connection with the registration for resale of
438,280 shares of Common Stock (the "shares"), as described in the Company's
Registration Statement on Form S-3 ("Registration Statement") filed with the
Securities and Exchange Commission under the Securities Act of 1933, as amended
(the "Act").

               This opinion is being furnished in accordance with the
requirements of Item 16 of Form S-3 and Item 601(b)(5)(i) of Regulation S-K.

               We have reviewed the Company's charter documents, the corporate
proceedings taken by the Company in connection with the original issuance and
sale of the shares and a certificate of a Company officer regarding (among other
things) the Company's receipt of consideration upon the original issuance and
sale of the shares. Based on such review, we are of the opinion that the shares
are duly authorized, validly issued, fully paid and nonassessable.

               We consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement and to the reference to this firm under the caption
"Legal Matters" in the prospectus which is part of the Registration Statement.
In giving this consent, we do not thereby admit that we are within the category
of persons whose consent is required under Section 7 of the Act, the rules and
regulations of the Securities and Exchange Commission promulgated thereunder or
Item 509 of Regulation S-K.

               This opinion letter is rendered as of the date first written
above and we disclaim any obligation to advise you of facts, circumstances,
events or developments which hereafter may be brought to our attention and which
may alter, affect or modify the opinion expressed herein. Our opinion is
expressly limited to the matters set forth above and we render no opinion,
whether by implication or otherwise, as to any other matters relating to the
Company or the Shares.


                                        Very truly yours,


                                        BROBECK HALE AND DORR

                       CONSENT OF INDEPENDENT ACCOUNTANTS


        We hereby consent to the incorporation by reference in this Registration
Statement on Form S-3 of our report dated August 10, 1999 relating to the
consolidated financial statements, which appears in the 1999 Annual Report to
Shareholders of Cisco Systems, Inc., which is incorporated by reference in Cisco
Systems, Inc.'s Annual Report on Form 10-K for the year ended July 31, 1999. We
