                                   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 940,202 shares (the "Shares") on behalf of certain
selling shareholders. All of the shares originally were issued by us in
connection with our acquisition of all outstanding shares of COCOM A/S. Cisco
acquired all of the outstanding shares of COCOM A/S and COCOM A/S is now a
wholly-owned subsidiary of Cisco. 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:

     -    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,

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

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

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

     -    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


                                       4
<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:

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

     -    the number of shares involved,

     -    the price at which such shares were sold,

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

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

     -    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 16.  EXHIBITS

2.1       Share Purchase Agreement by and between the Equity Holders of COCOM
          A/S, Denmark and Cisco Systems, Inc., USA dated as of the 14th of

2.2       Escrow Agreement, dated as of September 29, 1999, between Cisco
          Systems, Inc., State Street Bank and Trust Company of California, N.A.

5.1       Opinion of Brobeck Hale and Dorr
23.1      Consent of PricewaterhouseCoopers LLP
23.2      Consent of Brobeck Hale and Dorr (included in the Opinion of Brobeck
          Hale and Dorr filed as Exhibit 5.1 hereto)
24.1      Power of Attorney (included on page II-3 of this registration
          statement)

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.



                                      II-1
<PAGE>   10

     (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.

     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.

                hereof be deemed to include the contents of such Addendum.

          (a)   Documentation to the effect that each Seller has or will as of
                Closing obtain ownership of the portion of the Cisco Shares set

                account is duly transferred to the escrow account in the
                individual


                                       -8-

          amend the items of transaction that are to take place at Closing.

2.2.3     POST-CLOSING TRANSACTIONS. Cisco shall hold a general meeting of
          shareholders of the Company to elect new members of the Company's

          Registrar of the documents required in relation to the Warrantholders'
          exercise of their warrants into shares of Company common stock and
          DB's conversion of the Convertible Subordinated Loan.

2.3       SHARE EXCHANGE

2.3.1     EXCHANGE OF SHARES OF COMPANY'S COMMON STOCK. At the Effective Date,
          the Shares shall be assigned and transferred to Cisco in exchange for
          that number of shares of Cisco Common Stock (Cisco Shares) that equals
          that Seller's number of shares of Company's common stock with a par
          value of DKK 1.00 multiplied by the Exchange Ratio, adjusted according
          to the provisions of 2.3.4 if applicable.

2.3.2     THE CONVERTIBLE SUBORDINATED LOAN. DB agrees that the Convertible
          Subordinated Loan shall be converted into shares of Company's common
          stock at Closing and consequently such shares of Company's common
          stock will become subject to the provisions of Section 2.3.1.

2.3.3     WARRANTS. The Warrantholders agree to exercise their warrants at
          Closing and consequently become a Minority Shareholder upon Closing
          and become subject to the provisions of Section 2.3.1.

2.3.4     ADJUSTMENTS TO EXCHANGE RATIO. The Exchange Ratio shall be adjusted in
          the event of any Cisco Recapitalisation, being it a stock split,
          reverse split, stock dividend (including any dividend or distribution
          of securities


                                      -9-




<PAGE>   12



          convertible into Cisco common stock), reorganization, recapitalization
          or other like change with respect to Cisco common stock (a "Cisco
          Recapitalisation") occurring after the date hereof and prior to the
          Effective Date, so as to provide the Sellers and Cisco the same
          economic effect as contemplated by this Agreement prior to such stock
          split, reverse split, stock dividend, reorganization,
          recapitalization, like change or increase.


2.3.5     FRACTIONAL SHARES. No fraction of a share of the Cisco Shares will be
          issued by virtue of the exchange of shares as set forth in Section
          2.3.1. The amount of Cisco Shares to be issued to any Seller who would
          otherwise be entitled to a fraction of a share of the Cisco common
          stock shall be rounded up to the nearest whole number of Shares.


2.3.6     EXEMPTION FROM REGISTRATION. The Cisco Shares to be issued hereunder
          will be issued in a transaction exempt from registration under the

          properties, assets, liabilities, business, operations, results of
          operations or prospects of such person and its subsidiaries, taken as
          a whole, provided, however, that none of the following shall be deemed
          by itself or by themselves, either alone or in combination, to
          constitute a Material Adverse Effect on such person:

          (a)     any change in the market price or trading volume of such
                  person;

          (b)     with respect to Company, any adverse effect on the bookings,
                  revenues, gross margins or earnings of Company, or any delay

                  products, or any employee attrition, following execution of
                  this Agreement to the extent attributable to the announcement
                  of the execution of this Agreement and the transactions
                  contemplated hereby; or

          (c)     any change to the extent attributable to conditions affecting

                  technology, which conditions do not affect such person in a
                  materially disproportionate manner relative to other
                  participants in the economy or such industry, respectively.

          In this Agreement, any reference to the Sellers' "knowledge" means the
          knowledge of any Affiliate after diligent inquiry of the officers,
          directors and other employees charged with senior administrative or
          operational responsibility for such matters of the Company.

          to carry on its business as now being conducted and as currently
          proposed to be conducted, and is duly qualified and in good standing
          in each jurisdiction where the failure to be so qualified and in good
          standing would have a Material Adverse Effect on the Company. The
          Sellers have delivered a true and correct English translation of the
          latest corporate summary (Sammenskrevet resume) of the Company from
          the Danish Companies' Registrar, and of Company's presently registered
          Articles of Association as amended to date, including the filing dated

          or its Articles of Association or equivalent organizational documents.
          The Company has no subsidiaries and Company does not directly or
          indirectly own any equity interest in, or any interest convertible or
          exchangeable or exercisable for, any equity interest in, any
          corporation, partnership, joint venture or other business association
          or entity.

          Company has granted warrants (exercisable into 556,125 shares of
          Company Common Stock, DKK 1.00 par value) and has obtained a
          Convertible Subordinated Loan of which DKK 21,000,000 is outstanding,
          convertible into 1,000,000 shares of Company Common Stock, DKK 1.00
          par value. 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. All issued shares of Company
          Common Stock are duly authorized, validly issued, fully paid and
          non-assessable and are free of any liens or encumbrances other than
          any liens or encumbrances created by or imposed upon the holders
          thereof, and are not subject to preemptive rights or rights of first
          refusal created by statute, the charter documents of Company, or by
          agreement, except the provision of the Company's Articles of
          Association giving allowance for the protection of the pre-emptive
          rights and rights of first refusal, etc., subject to the Shareholders'
          Agreement dated 14 May 1999, attached hereto as Appendix 5, entered
          into in connection with the Company obtaining the Convertible
          Subordinated Loan, according to an Investment Agreement and a Loan
          Agreement of 14 May 1999 with DB, attached hereto as Appendix 6.

          None of the Company's shares are subject to stock purchase rights of
          any nature. There are no other options, warrants, calls, rights,
          commitments or agreements of any character to which the Company's
          shareholders and/or the Company are a party or by which these are
          bound, obligating Company to issue, deliver, sell, repurchase or
          redeem, or cause to be issued, delivered, sold, repurchased or
          redeemed, any shares of capital stock of Company or obligating Company
          to grant, extend, accelerate the vesting of, change the price of, or
          otherwise amend or enter into any such option, warrant, call, right,
          commitment or agreement. There are no other contracts, commitments or

          (i) between or among Company and any of its stockholders and (ii) to
          the knowledge of the Sellers, between or among any of Company's
          stockholders. The terms of the Company Warrant Plans do not permit the
          assumption of or substitution of warrants to purchase Cisco Common
          Stock, without the consent or approval of the holders of such
          warrants. True and complete copies of all agreements and instruments
          relating to or issued under the Company Warrant Plans have been
          delivered to Cisco and such agreements and instruments have not been
          amended, modified or supplemented other than as specifically
          contemplated by the provisions of this Agreement, and there are no
          agreements to amend, modify or supplement such agreements or
          instruments in any case from the form made available to Cisco, other
          than as expresly permitted by this Agreement.

          The Sellers are entitled to sell and transfer to Cisco the full legal
          and beneficial ownership of their Shares, free from all liens,
          options, charges, encumbrances, rights of pre-emption, rights of
          pledge or any other third party rights on the terms of this Agreement
          without the consent of any third party and no claim has been made by
          any person to be entitled to any of the foregoing. Included within
          Appendix 1 is a list of the Company's current shareholders, showing
          the record name of each such shareholder and the number of shares held
          by such shareholder.

          transactions contemplated hereby. The execution and delivery of this
          Agreement and the consummation of the transactions contemplated hereby
          have been duly authorized by all necessary action on the part of the
          Sellers. This Agreement has been duly executed and delivered by each
          Seller, and constitutes the valid and binding obligation of each such
          Seller, enforceable against them in accordance with its terms, except
          as enforceability may be limited by bankruptcy and other laws
          affecting the rights and remedies of creditors generally and general
          principles of equity.


                                      -14-
<PAGE>   17
          The execution and delivery of this Agreement by such shareholders does
          not, and the consummation of the transactions contemplated hereby will
          not, conflict with, or result in any violation of, or default under
          (with or without notice or lapse of time, or both), or give rise to a
          right of termination, cancellation or acceleration of any obligation
          or loss of any benefit under (i) any provision of the charter
          documents of Company, (ii) any mortgage, lease, contract or other
          agreement or instrument, permit, concession, franchise, license,
          judgment, order, decree, statute, law, ordinance, rule or regulation
          applicable to Company or any of its properties or assets which would
          have a Material Adverse Effect on the Company. No consent, approval,
          order or authorization of, or registration, declaration or filing
          with, any court, administrative agency or commission or other
          governmental authority ("Governmental Entity") is required by or with

          execution and delivery of this Agreement, or the consummation of the
          transactions contemplated hereby, except for (i) the filing of any
          amendments to the Company's Articles of Association as a consequence
          of the issuance of new shares as contemplated herein with the Danish
          Companies' Registrar; (ii) such consents, approvals, orders,
          authorizations, registrations, declarations and filings as may be

          and would not prevent, or materially alter or delay any of the
          transactions contemplated by this Agreement.

          or any of their respective officers or directors (in their capacities
          as such), or to which the Company is a party. There is no judgment,
          decree or order against Company, or any of their respective directors

          exemption was prepared and submitted by the Sellers on 3 September
          1999. If the approval stipulates as a condition precedent to
          tax-exemption for the Sellers that Cisco shall, for a specified

          the facts that formed

          last two (2) years, a summary of which is contained in Appendix 8.
          Subject to Section 6.2 below, the Sellers do not undertake any
          liability whatsoever and disclaim any liabilities as to the fact
          whether the transaction as contemplated in this Agreement will qualify

          this Agreement and until the Closing refrain from acting contrary to

          to cause to be delivered to the Sellers a letter of KPMG, the

          the assertions of the Company's management that no conditions exist
          that represent violations of certain of the specific conditions that
          must be met for pooling of interest accounting to be appropriate,
          including (i) autonomy, (ii) independence, (iii) change in equity
          interests, and (iv) treasury stock. A form Pooling Letter which is

                  though such representations and warranties were made on and as

                  Material Adverse Effect on the Company and except for failures
                  occurring in the ordinary course of the Company's business.

          (vii)   TAX TREATMENT. Cisco shall have received, reviewed and found
                  that nothing contained in the tax approval to be obtained by
                  the Sellers, see Section 5 above, is, in the opinion of Cisco,
                  materially adverse for Cisco.

10.       Conditions for Obligations of the Sellers

10.1      CLOSING. The Sellers' obligation to sell the Shares at Closing is, at
          the option of the Sellers, which may waive any such conditions,
          subject to the fulfilment on or prior to the Closing Date of the
          following conditions:

          (i)     REPRESENTATIONS AND WARRANTIES CORRECT. The representations
                  and warranties made by Cisco in Section 4 hereof shall be true
                  and correct as of the Effective Date as though such
                  representations and warranties were made on and as of such
                  time.

          (ii)    COVENANTS. All covenants, agreements and conditions contained
                  in this Agreement to be performed by Cisco on or prior to the
                  Effective Date shall have been performed or complied with in
                  all material respects.

          (iii)   CERTIFICATE OF CISCO. Company shall have been provided with a
                  certificate executed on behalf of Cisco by an individual
                  authorized to sign for Cisco certifying that the condition set
                  forth in Section 10.1(i) and (ii) shall have been fulfilled.

          (iv)    NO ORDER PENDING. There shall not at Closing be in effect any
                  order enjoining or restraining the transactions contemplated
                  by this Agreement.

          (v)     NO LAW PROHIBITING OR RESTRICTING SUCH SALE. There shall not
                  be in effect any law, rule or regulation prohibiting or
                  restricting the sale


                                      -40-
<PAGE>   43
                  of the shares of Company's Common Stock or other transactions
                  contemplated herein, or requiring any consent or approval of
                  any person which shall not have been obtained to issue the
                  shares of Cisco Common Stock (the Cisco Shares).

          (vi)    LISTING OF ADDITIONAL SHARES. The filing with the Nasdaq
                  National Market of a Notification Form for Listing of
                  Additional Shares with respect to the shares of Cisco Common
                  Stock issuable upon closing in exchange of the Company Common
                  Stock shall have been made.

          (vii)   TAX TREATMENT. The Sellers shall have received the applicable
                  approval for tax-exemption as an exchange of shares, see
                  Section 5 above.

11.       Covenant of Principal Equity Holders

11.1      The Principal Equity Holders covenant and agree that the Principal
          Equity Holders will procure the waiver by any Minority Shareholder or
          Warrantholder of applicable preemtpive rights, if any, relating to the
          Shares under any Shareholders' Agreement or the like thereof.

11.2      By signing this Agreement, each Seller recognizes in relation to
          Cisco, the Company and the other Sellers that the Company Equity
          Capital is as appears from Appendix 1, and that the Cisco Shares shall
          be distributed between the Sellers as set forth in Appendix 1.

12.       Escrow and Indemnification

12.1      ESCROW FUND. At Closing, Cisco shall deposit pursuant to the Escrow
          Agreement ten (10) percent of the Cisco Shares, exclusive of the
          portion of the Cisco Shares relating to the Company's treasury stock,
          with State Street Bank & Trust (or another institution selected by the
          Principal Equity Holders and Cisco) (the "Escrow Agent"), such deposit
          together with interest and other income and proceeds thereon to
          constitute the "Escrow Fund" and to be governed by the terms set forth


                                      -41-
<PAGE>   44
          herein and in the Escrow Agreement. Each of the Sellers agrees to be
          bound by the terms of the Escrow Agreement. The Escrow Fund shall be
          available to compensate Cisco pursuant to the indemnification
          obligations of the Sellers.

12.2      INDEMNIFICATION.

          (a) Subject to the limitations set forth in this Section 12, the
          Sellers will, on a pro rata basis in relation to each Seller's
          proportion of the Company Equity Capital as set forth in Appendix 1,
          indemnify and hold harmless Cisco and its officers, directors, agents
          and employees, and each person, if any, who controls or may control
          Cisco 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
          misrepresentation or breach of, or default in connection with, any of
          the representations, warranties, covenants and agreements given or
          made by the Sellers in this Agreement. Cisco will notify the
          Shareholders' Agent in accordance with Section 12.5 as soon as is
          reasonably practical with respect to each event or circumstance that
          gives rise to Damages that are subject to indemnification hereunder.
          The Escrow Fund shall be security for this indemnity obligation
          subject to the limitations in this Agreement.

          (b) Cisco and the Sellers each acknowledge that such Damages, if any,
          would relate to unresolved contingencies existing at the Effective
          Date, which if resolved at the Effective Time would have led to a
          reduction in the total number of shares Cisco would have agreed to
          issue in connection with the share exchange.

          (c) After Closing, recovery from the Escrow Fund shall be Cisco's
          exclusive remedy for any breach by the Sellers hereof or Damages
          described in Section 12.2(a);


                                      -42-
<PAGE>   45
          provided, however, that (i) in the event of any willful
          misrepresentation, any willful breach or any fraudulent conduct by any
          Seller, all Sellers shall be liable on a pro rata basis up and until
          their pro rata share, as set forth in Appendix 1, of the cash value of
          the Cisco Shares at the signing hereof; and (ii) nothing herein shall
          limit the liability of a Seller who has acted fraudulently.

          (d) If the transaction contemplated hereby does not close due to any
          negligence of any one Seller, the Sellers shall on a pro rata basis be
          liable towards Cisco up to an amount of USD 6,567,500, provided that
          the liability of a Seller shall not be limited if such Seller has
          acted fraudulently or such Seller has transferred or assigned rights
          to any third party in his portion of the Shares after signing.

12.3      INDEMNITY THRESHOLD AND CAP. Cisco may not receive any Cisco Shares
          from the Escrow Fund unless and until an Officer's Certificate or
          Certificates (as defined in Section 12.5 below), identifying Damages
          the aggregate amount of which exceeds USD 75,000 (the "Indemnity
          Threshold") has been delivered to the Escrow Agent as provided in
          Section 12.5 below and such amount is determined pursuant to this
          Section 12 to be payable, in either which case Cisco shall receive
          Cisco Shares equal in value to the full amount of Damages. In
          determining the amount of any Damage attributable to a specific
          breach, if the representation, warranty or covenant in question
          contains a materiality standard and it is determined that the specific
          event is in fact material, then the materiality standard contained
          therein shall be disregarded and the full amount of the Damages
          attributable to such breach shall be subject to the procedures set
          forth in this Section 12.

12.4      ESCROW PERIOD. The Escrow Period shall terminate (i) for those matters
          that are not expected to be encountered and resolved in the audit of
          Cisco's financial statements for its fiscal year because of
          materiality considerations or otherwise, at the one


                                      -43-
<PAGE>   46
          year anniversary of the Effective Date or (ii) for all other matters
          at the earlier of the one year anniversary of the Effective Date or
          the issuance of the audited consolidated financial statements of Cisco
          for its fiscal year which include the results of the Company;
          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. Cisco
          shall deliver to the Escrow Agent a certificate specifying the
          Effective Date.

12.5      CLAIMS UPON ESCROW FUND. Upon receipt by the Escrow Agent on or before
          the last day of the Escrow Period set out in Section 12.4 above of a
          certificate signed by any officer of Cisco (an "Officer's
          Certificate") (i) stating that, a claim under this present Section 12
          exists; and (ii) specifying in reasonable detail the individual items
          of such claim as well as the nature of the misrepresentation, breach
          of warranty or other action or omission on behalf of the Sellers that
          gave rise to the claim, the Escrow Agent shall, subject to Section
          12.6 and 12.7 below, deliver to Cisco out of the Escrow Fund, as
          promptly as practicable, cash or other assets held in the Escrow Fund
          having a value equal to the claim made. Any amounts paid out of the
          Escrow Fund to Cisco shall constitute a reduction of the consideration
          paid to the Sellers for the Company Equity Capital.

12.6      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 12.8 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 Cisco Common Stock pursuant to
          Section 12.5 hereof un-


                                      -44-
<PAGE>   47
          less the Escrow Agent shall have received written authorization from
          the Shareholders' Agent to make such delivery. After the expiration of
          such forty-five (45) day period, the Escrow Agent shall make delivery
          of Cisco Shares or other funds then in the Escrow Fund in accordance
          with Section 12.5 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 Cisco
          prior to the expiration of such forty-five (45) day period. Any such
          objection by the Shareholders' Agent need not include a specification
          of the reasons for the objection to be considered timely received.

12.7      RESOLUTION OF CONFLICTS; ARBITRATION.

          (a) In case the Shareholders' Agent shall so object in writing to any
          claim or claims by Cisco made in any Officer's Certificate, Cisco
          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 Cisco 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
          Cisco 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 Cisco Shares or other funds from the
          Escrow Fund in accordance with the terms thereof.

          (b) If no such agreement can be reached after good faith negotiation,
          either Cisco or the Sellers may refer the issue to arbitrations in
          accordance with Section 14.3 below.

12.8      SHAREHOLDERS' AGENT.


                                      -45-
<PAGE>   48

          (a) 2M Invest A/S shall be constituted and appointed as agent
          ("Shareholders' Agent") for and on behalf of the Sellers to give and
          receive notices and communications, to authorize delivery to Cisco
          from the Escrow Fund in satisfaction of claims by Cisco, 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 Cisco. 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
          Sellers. (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 Principal Equity Holders 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.

12.9      ACTIONS OF THE SHAREHOLDERS' AGENT. A decision, act, consent or
          instruction of the Shareholders' Agent shall constitute a decision of
          all Sellers and shall be final, binding and conclusive upon each
          Seller, and the Escrow Agent and Cisco may rely upon any decision,
          act, consent or instruction of the Shareholders' Agent as being the
          decision, act, consent or instruction of each and every such Seller.
          The Escrow Agent and Cisco are hereby relieved from any liability to
          any person for

                                      -46-
<PAGE>   49
          any acts done by them in accordance with such decision, act, consent
          or instruction of the Shareholders' Agent.

12.10     THIRD-PARTY CLAIMS. In the event Cisco becomes aware of a third-party
          claim which Cisco believes may result in a demand against the Escrow
          Fund, Cisco shall promptly notify the Shareholders' Agent of such
          claim, and the Shareholders' Agent shall be entitled, at the Sellers'
          expense, to participate in any defense of such claim. Cisco shall have
          the right in its sole discretion to settle any such claim; provided,
          however, that Cisco may not effect the settlement of any such claim
          without the 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 12.6 or any
          other provision of this Section 12 to the amount of any claim by Cisco
          against the Escrow Fund for indemnity with respect to such settlement.

13.       Indemnification of the Sellers

13.1      INDEMNITY OBLIGATION. Cisco will indemnify and hold harmless each
          Seller and its officers, directors, agents and employees and each
          person, who controls or may control any Seller (hereinafter referred
          to individually as an "Indemnified Person" or 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, arising out of any misrepresentation or breach of, or
          default in connection with, any of the representations, warranties,
          covenants and agreements given or made by Cisco in this Agreement. The
          Shareholders' Agent shall notify Cisco as soon as is reasonably
          practical with respect to each event or circumstance that gives rise
          to a claim against Cisco hereunder.

13.2      INDEMNITY THRESHOLD AND CAP. The Sellers shall not be entitled to
          indemnification unless and until the Share-


                                      -47-
<PAGE>   50

          holders' Agent has presented a claim in writing to Cisco identifying
          damages the aggregate amount of which exceeds USD 75,000 (the
          "Indemnity Threshold") and either Cisco agrees that such amount is
          payable, or an arbitration award to the effect that such amount is
          payable has been delivered, in either which case the Sellers shall be
          indemnified in the full amount of damages. In determining the amount
          of any damage attributable to a specific breach, if the
          representation, warranty or covenant in question contains a
          materiality standard and it is determined that the specific event is
          in fact material, then the materiality standard contained therein
          shall be disregarded and the full amount of the damages attributable
          to such breach shall be subject to the procedures set forth in this
          Section 13. If the transactions contemplated by this Agreement are
          consummated, the entire liability of Cisco hereunder shall be limited
          to the amount of USD 6,567,500, absent any fraud or willful misconduct
          on the part of Cisco.

13.3      INDEMNITY PERIOD. The period in which Cisco shall be under an
          obligation to indemnify the Sellers shall terminate (i) for those
          matters that are not expected to be encountered and resolved in the
          audit of Cisco's financial statements for its fiscal year because of
          materiality considerations or otherwise, at the one year anniversary
          of the Effective Date or (ii) for all other matters at the earlier of
          the one year anniversary of the Effective Date or the issuance of the
          audited consolidated financial statements of Cisco for its fiscal year
          which include the results of the Company, unless Cisco has been
          presented with a written claim from the Shareholders' Agent pursuant
          to Section 13.2 above prior to such time, in which event Cisco's
          obligation to indemnify the Sellers shall survive the expiry of the
          indemnity period with respect to the claims specified in the
          Shareholders' Agents' claim.

14.       Miscellaneous

14.1      LOANS AND GUARANTEES GRANTED BY 2M INVEST A/S. Cisco is informed of
          the obligations of the Company under a Loan

          that 2M Invest A/S is discharged of their obligations under the said
          guarantee obligations.

14.2      GOVERNING LAW. This Agreement shall be governed by and interpreted in
          accordance with the laws of Denmark, without reference to conflict of
          laws principles.

14.3      ARBITRATION. Any dispute or claim between the parties under this
          Agreement shall be finally settled by binding arbitration in
          accordance with the Rules of Procedure of the Danish Institute of
          Arbitration (Copenhagen Arbitration). For the purposes of this Section
          14.2, the Sellers shall be deemed to be one party. The Arbitration
          Tribunal shall be composed of three arbitrators. Each party shall
          appoint one arbitrator and the Arbitration Institute shall appoint a
          third arbitrator who shall chair the Tribunal. If a party has not
          appointed an arbitrator within thirty (30) days of having requested or
          received notice of the arbitration, such arbitrator shall be appointed
          by the Arbitration Institute. The place of arbitration shall be
          Copenhagen. The language of the arbitration shall be English.

14.4      SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and shall
          inure to the benefit of the parties hereto and their respective
          successors and assigns. This Agreement may not be assigned by a party

This Escrow Agreement is made as of 29 September 1999 by and among State Street
Bank and Trust Company of California, N.A. ("Escrow Agent"), Cisco Systems,
Inc., a California corporation ("Cisco"), and 2M Invest A/S, a Danish
corporation registered with the Companies' Registrar as company no. A/S 209.034,
as agent ("Shareholders' Agent") of the Sellers under the Share Purchase
Agreement of 14 September 1999, being the former shareholders, the lender under
a convertible subordinated loan, and holders of warrants to subscribe for common
stock of COCOM A/S, a Danish corporation registered with the Companies'
Registrar as company no. A/S 220.522 (the "Company"). Terms not otherwise
defined herein shall have the meaning set forth in the Share Purchase Agreement
(as defined below), a copy of which is attached hereto.

WITNESSETH

            WHEREAS, Cisco and the Sellers have entered into a Share Purchase
Agreement of 14 September 1999 (the "Share Purchase Agreement") providing for
the acquisition by Cisco of the Company Equity Capital by way of an exchange of
shares; and

            WHEREAS, pursuant to Section 12 of the Share Purchase Agreement,
entitled "Escrow and Indemnification" (the "Escrow and Indemnification Terms"),
an escrow fund (the "Escrow Fund") will be established to compensate Cisco for
certain Damages (as defined in the Escrow and Indemnification Terms) arising out
of any misrepresentation or breach or default in connection with any of the
representations, warranties, covenants and agreements given or made by the
Sellers in the Share Purchase Agreement, the Disclosure Schedule or any exhibit
or schedule to the Share Purchase Agreement; and

            WHEREAS, the Shareholders' Agent has been constituted as agent for
and on behalf of the Sellers to undertake certain obligations specified herein
and in the Escrow and Indemnification Terms; and

            WHEREAS, the Escrow and Indemnification Terms provides for an Escrow
Fund of 94,019 shares, being ten (10) per cent. of the Cisco Shares, exclusive
of the Cisco Shares relating to the Company's treasury stock, such escrow to be
held by the Escrow Agent; and

            WHEREAS, the parties hereto desire to set forth further terms and
conditions in addition to those set forth in the Escrow and Indemnification
Terms relating to the operation of the Escrow Fund.


                                      -1-
<PAGE>   3
            NOW, THEREFORE, the parties hereto, in consideration of the mutual
covenants contained herein, and intending to be legally bound, hereby agree as
follows:

1.        Escrow and Escrow Shares.

          Pursuant to the Escrow and Indemnification Terms and subject to any
          Cisco Recapitalization, Cisco shall deposit in escrow with the Escrow
          Agent within five (5) business days of the Effective Date (as defined
          in the Share Purchase Agreement), 94,019, in writing ninety four
          thousand and nineteen, Cisco Shares (the "Escrow Shares") which shall
          be registered in the name of the Escrow Agent as nominee for the
          Sellers. The Escrow Shares shall be held and distributed by the Escrow
          Agent in accordance with the terms and conditions of the Escrow and
          Indemnification Terms and this Agreement. The number of Escrow Shares
          beneficially owned by each Seller, the percentage interest of each
          Seller in the Escrow Fund, the address of each Seller and the taxpayer
          identification of each Seller are set forth in Annex 1 attached
          hereto.

2.        Rights and Obligations of the Parties.

          The Escrow Agent shall be entitled to such rights and shall perform
          such duties of the escrow agent as set forth herein and in the Escrow
          and Indemnification Terms (collectively, the "Duties"), in accordance
          with the terms and conditions of this Agreement and the Escrow and
          Indemnification Terms. Cisco, the Company and the Shareholders' Agent
          shall be entitled to their respective rights and shall perform their
          respective duties and obligations as set forth herein and in the
          Escrow and Indemnification Terms, in accordance with the terms hereof
          and thereof. In the event that the terms of this Agreement conflict in
          any way with the provisions of the Escrow and Indemnification Terms,
          the Escrow and Indemnification Terms shall control.


                                      -2-
<PAGE>   4
3.        Escrow Period.

          The Escrow Period shall terminate (i) for those matters that are not
          expected to be encountered and resolved in the audit of Cisco's
          financial statements for its fiscal year because of materiality
          considerations or otherwise, at the one year anniversary of the
          Effective Date or (ii) for all other matters at the earlier of the one
          year anniversary of the Effective Date or the date set forth in an
          Officers' Certificate of Cisco, delivered to the Escrow Agent, as
          being the date of the issuance of the audited consolidated financial
          statements of Cisco for its fiscal year which include the results of
          the Company; 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. Cisco
          immediately shall deliver to the Escrow Agent a certificate specifying
          the Effective Date and, later, shall deliver to the Escrow Agent a
          certificate setting forth the date on which the Escrow Period
          terminates. Upon the expiration of the Escrow Period, Cisco shall
          deliver to the Escrow Agent a certificate setting forth as of the date
          of such termination the Nasdaq National Market closing price of Cisco
          Common Stock (the "Termination Stock Price").

4.        Duties of Escrow Agent.

          In addition to the Duties set forth in the Escrow and Indemnification
          Terms, the Duties of the Escrow Agent shall include the following:

4.1       The Escrow Agent shall hold and safeguard the Escrow Shares during the
          Escrow Period, shall treat such Escrow Fund as a trust fund in
          accordance with the terms of this Agreement and the Escrow and
          Indemnification Terms and not as the property of Cisco, and shall hold
          and dispose of the Escrow Shares only in accordance with the terms
          hereof.

4.2       The Escrow Shares shall be voted by the Escrow Agent in accordance
          with the instructions received by the Escrow Agent from the beneficial


                                      -3-
<PAGE>   5
          owners of such shares. In the absence of such instructions, the Escrow
          Agent shall be under no obligation to vote such shares. The Escrow
          Agent need not forward proxy information, annual or other reports or
          other information received from Cisco with respect to the Escrow
          Shares.

4.3       Promptly following termination of the Escrow Period as set forth in
          Section 3 hereof, if necessary, the Escrow Agent (i) shall deposit
          with the Cisco's stock transfer agent (which is currently Boston
          EquiServe LP) the number of Escrow Shares and other property in the
          Escrow Fund which is in excess of the amount of such Escrow Shares or
          other property (as set forth in a certificate of Cisco) which is
          determined to be sufficient to satisfy any unsatisfied claims made by
          Cisco and delivered to the Escrow Agent prior to termination of the
          Escrow Period, and to pay expenses as provided in Section 9.2 hereof
          and (ii) shall cause such transfer agent to transfer such Escrow
          Shares and other property to the Sellers. As soon as all such claims
          have been resolved, the Escrow Agent shall cause such transfer agent
          to deliver to such Sellers all of the Escrow Shares and other property
          remaining in the Escrow Fund and not required to satisfy such claims
          and expenses. Each Seller shall receive that number of Escrow Shares
          equivalent to such Seller's percentage interest in the Escrow Fund as
          set forth in Annex 1 hereto.

4.4       Pursuant to Section 12 of the Share Purchase Agreement, for the
          purpose of compensating Cisco for its Damages pursuant to the Share
          Purchase Agreement, the Escrow Shares shall be valued on the basis of
          the closing price of Cisco Common Stock on the Nasdaq National Market
          on the trading day before the date of an Officer's Certificate
          presented pursuant to Section 12.5 of the Share Purchase Agreement
          (the "Claim Stock Price"). The Claim Stock Price shall be set forth in
          such Officer's Certificate. If the value to be distributed to Cisco
          (or to any Seller upon a termination of the escrow) is not evenly
          divisible by the Claim Stock Price or the Termination Stock Price, as
          applicable, the Escrow Agent shall round down the number of shares to
          be distributed to the next highest number of shares and shall cause
          the transfer agent of the Escrow Shares to distribute that number. In
          lieu of the fractional interest not distributed, Cisco shall furnish
          to the Escrow Agent, and the Escrow Agent (or such stock transfer
          agent) in turn


                                      -4-
<PAGE>   6
          will distribute to Cisco, cash equal to such fractional interest times
          the Claim Stock Price or the Termination Stock Price, as applicable.
          Cisco shall be deemed to have purchased such fractional interests with
          respect to which it has furnished funds to the Escrow Agent.
          Accordingly, the Escrow Agent, upon receipt of such funds, shall
          deliver the corresponding number of shares to Cisco. In all events,
          Cisco shall so purchase only a whole number of shares. Any cash so
          received from Cisco and not so immediately distributed by the Escrow
          Agent shall be retained by the Escrow Agent as part of the Escrow
          Fund, but need not be invested.

5.        Distribution.

          Any cash dividends, dividends payable in securities or other
          distributions of any kind (but excluding any shares of Cisco capital
          stock received upon a stock split or stock dividend) shall be promptly
          distributed by the Escrow Agent to the beneficial holder of the Escrow
          Shares to which such distribution relates, by check mailed via first
          class mail, to the Sellers at their addresses, and in the percentage
          interests, set forth in Annex 1. Any shares of Cisco common stock
          received by the Escrow Agent upon a stock split made in respect of any
          securities in the Escrow Fund shall be added to the Escrow Fund and
          become a part thereof. Any provision hereof or of the Escrow and
          Indemnification Terms shall be adjusted to appropriately reflect any
          stock split or reverse stock split, as set forth in a revised version
          of Annex 1 delivered to the Escrow Agent and the Shareholders' Agent.

6.        Exculpatory Provisions.

6.1       The Escrow Agent shall be obligated only for the performance of such
          Duties as are specifically set forth herein and in the Escrow and
          Indemnification Terms and may rely and shall be protected in relying
          or refraining from acting on any instrument reasonably believed to be
          genuine and to have been signed or presented by the proper party or
          parties. The Escrow Agent shall not be liable for forgeries or false
          personations. The Escrow Agent shall not be liable for any act done or
          omitted hereunder as escrow agent except for gross negligence or
          willful misconduct. The Escrow Agent shall, in no case or event be
          liable for any representations or warranties of the Company or Cisco


                                      -5-
<PAGE>   7
          or for punitive, incidental or consequential damages. Any act done or
          omitted pursuant to the advice or opinion of counsel shall be
          conclusive evidence of the good faith of the Escrow Agent.

6.2       The Escrow Agent is hereby expressly authorized to disregard any and
          all warnings given by any of the parties hereto or by any other
          person, excepting only orders or process of courts of law or
          arbitrations as provided in Sections 12.7 and 14.3 of the Share
          Purchase Agreement, and is hereby expressly authorized to comply with
          and obey orders, judgments or decrees of any court or rulings of any
          arbitrators. In case the Escrow Agent obeys or complies with any such
          order, judgment or decree of any court or such ruling of any
          arbitrator, the Escrow Agent shall not be liable to any of the parties
          hereto or to any other person by reason of such compliance,
          notwithstanding any such order, judgment, decree or arbitrators'
          ruling being subsequently reversed, modified, annulled, set aside,
          vacated or found to have been entered without jurisdiction.

6.3       The Escrow Agent shall not be liable in any respect on account of the
          identity, authority or rights of the parties executing or delivering
          or purporting to execute or deliver the Agreement or any documents or
          papers deposited or called for thereunder.

6.4       The Escrow Agent shall not be liable for the outlawing of any rights
          under any statute of limitations with respect to the Agreement or any
          documents deposited with the Escrow Agent.

7.        Resignation and Removal of the Escrow Agent.

          The Escrow Agent may resign as Escrow Agent at any time with or
          without cause by giving at least thirty (30) days' prior written
          notice to each of Cisco and the Shareholders' Agent, such resignation
          to be effective thirty (30) days following the date such notice is
          given. In addition, Cisco and the Shareholders' Agent may jointly
          remove the Escrow Agent as escrow agent at any time with or without
          cause, by an instrument (which may be executed in counterparts) given
          to the Escrow Agent, which instrument shall designate the effective
          date of such removal. In the event of any such resignation or removal,
          a successor escrow agent which shall be a bank or trust company


                                      -6-
<PAGE>   8
          organized under the laws of the United States of America or of the
          State of California having (or if such bank or trust company is a
          member of a bank company, its bank holding company shall have) a
          combined capital and surplus of not less than $50,000,000, shall be
          appointed by the Shareholders' Agent with the approval of Cisco, which
          approval shall not be unreasonably withheld. Any such successor escrow
          agent shall deliver to Cisco and the Shareholders' Agent a written
          instrument accepting such appointment, and thereupon it shall succeed
          to all the rights and duties of the escrow agent hereunder and shall
          be entitled to receive the Escrow Fund.

8.        Further Instruments.

          If the Escrow Agent reasonably requires other or further instruments
          in connection with performance of the Duties, the necessary parties
          hereto shall join in furnishing such instruments.

9.        Escrow Fees and Expenses.

9.1       Cisco shall pay the fees of the Escrow Agent.

9.2       Any out-of-pocket expenses incurred by the Shareholders' Agent shall
          be paid out of the Escrow Fund in preference to other distributions
          from such Escrow Fund; provided, however, that the aggregate of such
          payments shall not exceed $15,000, and provided further that under no
          circumstances will the Shareholders' Agent have personal liability for
          any such expenses.

10.       Indemnification.

          In consideration of the Escrow Agent's acceptance of this appointment,
          Cisco and the Shareholders' Agent, on behalf of the Sellers of the
          Company and not individually, jointly and severally, agree to
          indemnify and hold the Escrow Agent harmless as to any liability
          incurred by it to any person, firm or corporation by reason of its
          having accepted such appointment or in carrying out the terms hereof
          and of the Escrow and Indemnification Terms, and to reimburse the
          Escrow Agent for all its costs and expenses, including, among other
          things, counsel fees and expenses, reasonably incurred by reason of


                                      -7-
<PAGE>   9
          any matter as to which an indemnity is paid; provided, however, that
          no indemnity need be paid in case of the Escrow Agent's negligence,
          willful misconduct or breach of this Agreement.

11.       Notices.

          Any notice given hereunder shall be in writing and shall be deemed
          effective upon the earlier of personal delivery or the third day after
          mailing by certified or registered mail, postage prepaid, or sent via
          facsimile (with confirmation of receipt) to the parties at the

          interpretation of any provision of this Escrow Agreement.

12.2      This Escrow Agreement may be executed in any number of counterparts,
          each of which when so executed shall constitute an original copy
          hereof, but all of which together shall constitute one agreement.

12.3      No party may, without the prior express written consent of each other
          party, assign this Escrow Agreement in whole or in part. This Escrow
          Agreement shall be binding upon and inure to the benefit of the
          respective successors and assigns of the parties hereto.

12.4      It is understood and agreed that should any dispute arise with respect
          to the delivery and/or ownership or right of possession of the
          securities held by the Escrow Agent hereunder, the Escrow Agent is
          authorized and directed to act in accordance with, and in reliance
          upon, the terms hereof and of the Escrow and Indemnification Terms.

12.5      This Escrow Agreement shall be governed by and construed in accordance
          with the laws of the Kingdom of Denmark. Any dispute or claim between

          principal of which is invested solely in obligations issued or
          guaranteed by the United States Government. All interest or any other
          income earned with respect to such investment shall be retained by the

          documents that the Escrow Agent may reasonably request (collectively,
          "Tax Reporting Documentation") to the Escrow Agent within 30 days
          after the date hereof. The parties hereto understand that, if such Tax
          Reporting Documentation is not so certified to the Escrow Agent, the

          monies or other property held by the Escrow Agent pursuant to this
          Agreement.

                        OPINION OF BROBECK HALE AND DORR

          Re:  Cisco Systems, Inc. Registration Statement on Form S-3 for Resale
               of 940,202 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 940,202
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

Statement on Form S-3 of our report dated August 10, 1999 relating to the
