                                                                    ---------

 
ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The Bylaws of the Company provide for the indemnification of the Company's
officers and directors against certain liabilities and expenses relating to
lawsuits and other proceedings in which they may become involved. Section 317 of
the California Corporations Code also provides for indemnification of a
corporation's directors and officers under certain circumstances.
 
    Section 204(a)(10) and (11) and Section 317 of the California Corporations
Code and the Bylaws of the Company contain provisions covering indemnification
of corporate directors and officers against certain liabilities and expenses
incurred as a result of proceedings involving such persons in their capacities
as directors and officers, including proceedings under the Securities Act or the
Exchange Act.
 
    The Company provides indemnity insurance pursuant to which its directors and
officers are indemnified or insured under certain circumstances against certain
liabilities or losses, including liabilities under the Securities Act. The
Company has obtained shareholder approval to enter into indemnity agreements
with their respective directors and officers. Each agreement provides for
indemnification of the fines, settlements and other amounts incurred by such
person in connection with the good faith performance of his or her duties as a
director or officer. The indemnification agreements also provide for the advance
payment by the Company of expenses incurred in defending any proceeding to which
the director or officer may be a party, provided that the affected director or
officer executed an undertaking, acceptable to the disinterested members of the
board of directors, agreeing to repay all amounts advanced for defense of the
proceeding if it shall be ultimately determined that such director or officer
was not entitled to be indemnified in accordance with Sections 204(a)(10) and
(11) and Section 317 of the California Corporations Code.
 
    The Company understands that the staff of the Commission is of the opinion
that statutory, charter and contractual provisions as are described above have
no effect on claims arising under the federal securities laws.
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES
 
    Since 1994 the registrant has issued and sold the following unregistered
securities: as of April 30, 1997, the Registrant has issued and sold 186,832
shares of Common Stock to employees and consultants at prices
 
                                      II-1

ranging from $.033 to $10.50 per share, upon exercise of stock options, pursuant
to the Registrant's 1994 Stock Option Plan; in December 1995, the Company issued
15,000 shares of Common Stock to Douglas Meltzer in consideration of past
services rendered to the Company and the signing of a confidentiality agreement;
and in connection with the Company's acquisition of certain assets, with a value
of $189,000 as determined by the Company's Board of Directors, of Lloyd
Internetworking, Inc. ("Lloyd") in June 1996, the Company issued 18,000 shares
of Common Stock to Lloyd shareholders.
 
    The sales of the above securities were deemed to be exempt from registration
under the Securities Act in reliance on Section 4(2) of the Securities Act, or
Rule 701 promulgated under Section 3(b) of the Securities Act, as transactions
by an issuer not involving a public offering or transactions pursuant to
compensatory benefit plans and contracts relating to compensation as provided
under such Rule 701. The recipients of securities in each such transaction
represented their intention to acquire the securities for investment only and
not with a view to or for sale in connection with any distribution thereof and
appropriate legends were affixed to the share certificates and instruments
issued in such transaction. All recipients had adequate access, through their
relationships with the Company, to information about the Registrant.

ITEM 17.  UNDERTAKINGS
 
    The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
    Insofar as indemnification by the Registrant for liabilities arising under
the Securities Act may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the provisions referenced in Item 14 of
this Registration Statement 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 (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:
 
    (1) For purposes of determining any liability under the Securities Act, the
information omitted from the form of Prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act,
each post-effective amendment that contains a form of Prospectus 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-3

                                   SIGNATURES
 
   
    Pursuant to the requirements of the Securities Act, the Registrant has duly
caused this Registration Statement to be signed on its behalf by the
undersigned, thereunto duly authorized, in the City of Pleasanton, State of
California, on the 28th day of May, 1997.
