Cisco Systems, Inc.
170 West Tasman Drive
San Jose, California 95134-1706
Re: Cisco Systems, Inc. - Registration Statement for
Offering of an Aggregate of Shares of Common
Stock
Dear Ladies and Gentlemen:
We have acted as counsel to Cisco Systems, Inc., a California
corporation (the "Company"), in connection with the registration on Form S-8
(the "Registration Statement") under the Securities Act of 1933, as amended, of
an aggregate of 531,724 shares of common stock (the "Shares") and related stock
options under the Atlantech Technologies Limited U.K. Unapproved Share Option
Scheme 1995, the Atlantech Technologies Limited U.K. Unapproved Share Option
Scheme 1999, the Atlantech Technologies Limited 1998 Stock Option Plan and the
JetCell, Inc. 1998 Stock Plan (the "Plans").
This opinion is being furnished in accordance with the
requirements of Item 8 of Form S-8 and Item 601(b)(5)(i) of Regulation S-K.
We have reviewed the Company's charter documents and the
corporate proceedings taken by the Company in connection with the assumption of
the Plans and the options outstanding thereunder. Based on such review, we are
of the opinion that if, as and when the Shares are issued and sold (and the
consideration therefor received) pursuant to the provisions of option agreements
duly authorized under the Plans and in accordance with the Registration
Statement, such Shares will be duly authorized, legally issued, fully paid and
nonassessable.
We consent to the filing of this opinion letter as Exhibit 5 to
the Registration Statement.
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, the Plans or the Shares.
Very truly yours,
