PART II
INFORMATION NOT REQUIRED IN PROSPECTUS
ITEM 20. 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 22. UNDERTAKINGS.
The undersigned Registrant hereby undertakes:
1. 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 Securities Exchange Act of 1934, as amended (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 this 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 a bona fide offering thereof;
2. That, prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this Registration Statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c) of the Securities Act, such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form;
3. That every prospectus (i) that is filed pursuant to paragraph (2) immediately preceding, or (ii) that purports to meet the requirements of
Section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to this Registration Statement and will not be used until such amendment is effective, and that, for purposes 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;
4. To respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of Form S-4, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of this Registration Statement through the date of responding to the request; and
5. To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in this Registration Statement when it became effective.
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 provisions described under Item 20 above, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities
II-2

(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.

Ladies and Gentlemen:
This opinion is being delivered to you in connection with (i) the Agreement and Plan of Merger and Reorganization (the "Agreement") dated as of May 4, 2000, between Cisco Systems, Inc., a California corporation ("Parent"), Archer Acquisition Corporation, a Delaware corporation and a wholly owned subsidiary of Parent ("Merger Sub"), and Arrowpoint Communications, Inc., a Delaware corporation ("Target"), and (ii) the preparation and filing with the Securities and Exchange Commission of a Form S-4 Registration Statement relating to the Merger (the "Registration Statement"). Pursuant to the Agreement, Merger Sub will merge with and into Target (the "Merger"), and Target will become a wholly owned subsidiary of Parent.
Except as otherwise provided, capitalized terms referred to herein have the meanings set forth in the Agreement. All section references, unless otherwise indicated, are to the Internal Revenue Code of 1986, as amended (the "Code").
We have acted as legal counsel to Parent in connection with the Merger. As such, and for the purpose of rendering this opinion, we have examined and are relying upon (without any independent investigation or review thereof) the truth and accuracy, at all relevant times, of the statements, covenants, representations and warranties contained in the following documents (including all schedules and exhibits thereto):
1. The Agreement;
2. The Registration Statement; and
3. Such other instruments and documents related to Parent, Target, Merger Sub and the Merger as we have deemed necessary or appropriate.
In connection with rendering this opinion, we have assumed or obtained representations (and are relying thereon, without any independent investigation or review thereof) that:
A. Original documents submitted to us (including signatures) are authentic, documents submitted to us as copies conform to the original documents, and there has been (or will be by the Effective Time) due execution and delivery of all documents where due execution and delivery are prerequisites to the effectiveness thereof; and
B. The Merger will be consummated in accordance with the Agreement without any waiver or breach of any material provision thereof, and the Merger will be effective under applicable state law.

Cisco Systems, Inc. May 8, 2000

Based on our examination of the foregoing items and subject to the assumptions, exceptions, limitations and qualifications set forth herein, we are of the opinion that the statements regarding United States federal income tax consequences set forth in the Registration Statement under the heading "Federal Income Tax Considerations," insofar as they constitute statements of law or legal conclusions, are correct in all material respects. We express no opinion as to any federal, state or local, foreign or other tax consequences, other than as set forth in the Registration Statement under the heading "Federal Income Tax Considerations."
In addition to the assumptions and representations described above, this opinion is subject to the exceptions, limitations and qualifications set forth below.
(1) This opinion represents and is based upon our best judgment regarding the application of federal income tax laws arising under the Code, existing judicial decisions, administrative regulations and published rulings and procedures. Our opinion is not binding upon the Internal Revenue Service or the courts, and there is no assurance that the Internal Revenue Service will not successfully assert a contrary position. Furthermore, no assurance can be given that future legislative, judicial or administrative changes, on either a prospective or retroactive basis, will not adversely affect the accuracy of the conclusions stated herein. Nevertheless, we undertake no responsibility to advise you of any new developments in the application or interpretation of the federal income tax laws.
(2) No opinion is expressed as to any transaction other than the Merger (whether or not undertaken in connection with the Merger) or as to any transaction whatsoever, including the Merger, if all the transactions described in the Agreement are not consummated in accordance with the terms of such Agreement and without waiver or breach of any material provision thereof or if all of the statements, representations, warranties and assumptions upon which we relied are not true and accurate at all relevant times. In the event any one of the statements, representations, warranties or assumptions upon which we have relied to issue this opinion is incorrect, our opinion might be adversely affected and may not be relied upon.
This opinion is rendered to you solely in connection with the filing of the Registration Statement. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement. We also consent to the references to our firm name wherever appearing in the Registration Statement with respect to the discussion of the federal income tax consequences of the Merger, including any amendments to the Registration Statement. This opinion may not be relied upon for any other purpose, and may not be made available to any other person, without our prior written consent.
Very truly yours,
BROBECK, PHLEGER & HARRISON LLP

Re: Merger pursuant to Agreement and Plan of Merger and Reorganization dated as of May 4, 2000 among Cisco Systems, Inc., Archer Acquisition Corporation and Arrowpoint Communications, Inc.
Ladies and Gentlemen:
This opinion is being delivered to you in connection with the filing of a registration statement (the "Registration Statement") on Form S-4, which includes the Joint Proxy Statement and Prospectus relating to the Agreement and Plan of Merger and Reorganization dated as of May 4, 2000 (the "Merger Agreement"), by and among Cisco Systems, Inc., a California corporation ("Parent"), Archer Acquisition Corp., a Delaware corporation and wholly owned subsidiary of Parent ("Acquisition"), and Arrowpoint Communications, Inc., a Delaware corporation ("Company"). Pursuant to the Merger Agreement, Acquisition will merge with and into Company (the "Merger"). Except as otherwise provided, capitalized terms not defined herein have the meanings set forth in the Merger Agreement and the exhibits thereto or in the letters to be delivered pursuant to the Merger Agreement to Hale and Dorr LLP by Parent and Company containing certain representations of Parent and Company relevant to this opinion (the "Representation Letters"). All section references, unless otherwise indicated, are to the United States Internal Revenue Code of 1986, as amended (the "Code").
In our capacity as counsel to Company in the Merger, and for purposes of rendering this opinion, we have examined and relied upon the Registration Statement, the Merger Agreement and the exhibits thereto and such other documents as we considered relevant to our analysis. In our examination of documents, we have assumed the authenticity of original documents, the accuracy of copies, the genuineness of signatures, and the legal capacity of signatories.
We have assumed that all parties to the Merger Agreement and to any other documents examined by us have acted, and will act, in accordance with the terms of such Merger Agreement and documents and that the Merger will be consummated at the Effective Time pursuant to the terms and conditions set forth in the Merger Agreement without the waiver or modification of any such terms and conditions. Furthermore, we have assumed that all representations contained in the Merger Agreement, as well as those representations to be contained in the Representation Letters when delivered, are, at the Effective Time, and at any relevant future date, will be, true and complete in all material respects, and that any representation made or to be made in any of the documents referred to herein "to the best of the knowledge and belief" (or similar qualification) of any person or party is correct without such qualification. We have also assumed that as to all matters for which a person or entity has represented that such person or entity is not a party to, or does not have, or is not aware of, any plan, intention, understanding, or agreement, there is no such plan, intention, understanding or agreement. We have not attempted and will not attempt, to verify independently such representations, including representations relating to future conduct.
The conclusions expressed herein represent our judgment as to the proper treatment of certain aspects of the Merger under the income tax laws of United States based upon the Code, Treasury Regulations, case law, and rulings and other pronouncements of the Internal Revenue Service (the

"IRS") as in effect on the date of this opinion. No assurances can be given that such laws will not be amended or otherwise changed prior to the Effective Time, or at any other time, or that such changes will not affect the conclusions expressed herein. Nevertheless, we undertake no responsibility to advise you of any developments after the Effective Time in the application or interpretation of the income tax laws of the United States.
Our opinion represents our best judgment of how a court would decide if presented with the issues addressed herein and is not binding upon either the IRS or any court. Thus, no assurances can be given that a position taken in reliance on our opinion will not be challenged by the IRS or rejected by a court.
This opinion addresses only the specific United States federal income tax consequence of the Merger set forth below, and does not address any other federal, state, local, or foreign income, estate, gift, transfer, sales, use, or other tax consequences that may result from the Merger or any other transaction (including any transaction undertaken in connection with the Merger).
On the basis of, and subject to, the foregoing, and in reliance upon the representations and assumptions described above, we are of the opinion that the discussion contained in the Registration Statement under the caption "Federal Income Tax Consequences," subject to the limitations and qualifications described therein, sets forth the material United States Federal income tax considerations generally applicable to the Merger. Because this opinion is being delivered prior to the Effective Time of the Merger, it must be considered prospective and dependent on future events. There can be no assurance that changes in the law will not take place which could affect the United States Federal income tax consequences of the Merger or that contrary positions may not be taken by the Internal Revenue Service.
In rendering this opinion, we have assumed that Brobeck Phleger & Harrison LLP has delivered, and has not withdrawn, an opinion that is substantially similar to this one. No opinion is expressed as to any federal income tax consequence of the Merger except as specifically set forth herein, and this opinion may not be relied upon except with respect to the consequence specifically discussed herein.
This opinion is intended solely for the purpose of inclusion as an exhibit to the Registration Statement. It may not be relied upon for any other purpose or by any other person or entity, and may not be made available to any other person or entity without our prior written consent. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and further consent to the use of our name in the Registration Statement in connection with the references to this opinion and the tax consequences of the Merger. In giving this consent, however, we do not hereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended, or the rules and regulations of the Securities and Exchange Commission thereunder, nor do we thereby admit that we are experts with respect to any part of such Registration Statement within the meaning of the term "experts" as used in the Securities Act of 1933, as amended, or the rules and regulations of the Securities and Exchange Commission thereunder.
Very truly yours,
