ITEM 5.  OTHER EVENTS

     On October 25, 2000, GaSonics International Corporation ("GaSonics")
entered into an Agreement and Plan of Reorganization (the "Merger Agreement")
with Novellus Systems, Inc. ("Novellus"), a Delaware corporation, and Neptune
Acquisition-Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of
Novellus. If the merger is completed, GaSonics will become a wholly-owned
subsidiary of Novellus and each outstanding share of GaSonics common stock will
be converted into the right to receive 0.52 of a share of Novellus common stock.

     GaSonics, its directors, executive officers and certain other members of
management and employees may be soliciting proxies from GaSonics stockholders
in favor of the adoption and approval of the Merger Agreement and approval of
the merger and related matters, including: Asuri Raghavan (Chief Executive
Officer, President and Director), Jerauld J. Cutini (Senior Vice President of
Marketing and Business Development), Rammy Rasmussen (Vice President of
Finance, Chief Financial Officer and Secretary), Bill Alexander (Vice
President, Worldwide Sales and Field Operations), Graham Hills (Vice
President, Chief Technical Officer), John Villadsen (Vice President,
Manufacturing Operations), Dave Toole (Chairman of the Board of Directors),
Monte M. Toole (Vice Chairman of the Board of Directors), Kenneth L. Schroeder
(Director), Kenneth M. Thompson (Director), and F. Joseph Van Poppelen
(Director). Certain information concerning the participants in the
solicitation is set forth below. Additional information will be set forth in
the Registration Statement and the Proxy Statement/Prospectus that are
expected to be filed with the Securities and Exchange Commission in connection
with the merger. In connection with the merger, certain directors and officers
of GaSonics holding an aggregate of approximately 3,462,564 shares of GaSonics
common stock and options to acquire shares of GaSonics common stock, their
beneficial ownership representing approximately 15.94% of GaSonics' 17,026,462
shares outstanding as of September 15, 2000 (including shares subject to
options exercisable within 60 days that are covered by the voting agreements),
have entered into voting agreements, dated October 25, 2000 (the "Voting
Agreements"), and irrevocable proxies (the "Irrevocable Proxies"), pursuant to
which they have agreed to vote their GaSonics shares in favor of the adoption
and approval of the Merger Agreement and approval of the merger and related
matters.

     Mr. Raghavan beneficially owns 402,000 shares of GaSonics common stock,
including 400,000 shares issuable upon exercise of options, 174,998 of which are
exercisable within 60 days. Mr. Cutini beneficially owns 158,000 shares of
GaSonics common stock, including 150,000 shares issuable upon exercise of
options, of which 24,999 are exercisable within 60 days. Mr. Rasmussen
beneficially owns 52,000 shares of GaSonics common stock, including 50,000
shares issuable upon exercise of options, none of which are exercisable within
60 days. Mr. Alexander beneficially owns 114,564 shares of GaSonics common
stock, including 95,000 shares issuable upon exercise of options, 27,994 of
which are exercisable within 60 days. Mr. Hills beneficially owns 65,874 shares
of GaSonics common stock, including 65,000 shares issuable upon exercise of
options, 17,707 of which are exercisable within 60 days. Mr. Villadsen
beneficially owns 60,422 shares of GaSonics common stock, including 60,000
shares issuable upon exercise of options, 14,062 of which are exercisable within
60 days. Mr. Dave Toole beneficially owns 793,976 shares of GaSonics common
stock, including 245,068 shares issuable upon exercise of options, 169,998 of
which are exercisable within 60 days. Mr. Monte M. Toole beneficially owns
1,685,728 shares of GaSonics common stock. Mr. Schroeder beneficially owns
options to purchase 45,000 shares of GaSonics common stock, 37,500 of which are
exercisable within 60 days. Mr. Thompson beneficially owns options to purchase
30,000 shares of GaSonics common stock, 15,000 of which are exercisable within
60 days. Mr. Van Poppelen beneficially owns 55,000 shares of GaSonics common
stock, including 45,000 shares issuable upon exercise of options, 37,500 of
which are exercisable within 60 days. Under the terms of applicable option
documents, certain of the options listed above which are not presently
exercisable and vested will become immediately exercisable and vested upon the
completion of the merger.

     In addition to their holdings of GaSonics common stock and options, Mr.
Dave Toole, Chairman of GaSonics' Board of Directors, and Mr. Monte M. Toole,
Vice Chairman of GaSonics' Board of Directors, each hold 1,500 shares of
Novellus common stock; Mr. Raghavan, Chief Executive Officer, President and
Director, holds 1,000 shares of Novellus common stock; and Mr. Van Poppelen,
Director, holds 55,000 shares of Novellus common stock.  Their Novellus holdings
were disclosed to the Board of Directors of GaSonics in connection with its
consideration of the merger.  Mr. Van Poppelen did not participate in the vote
of the GaSonics Board of Directors with respect to the Merger Agreement, the
merger or any related matters.  All other members of GaSonics' Board of
Directors voted in favor of the Merger Agreement, merger and related matters.

Employment arrangements

In connection with the Merger, Mr. Raghavan and certain other members of
GaSonics' management have received or expect to receive offers of employment
with Novellus following the completion of the merger, with cash compensation,
benefits and option grants which are comparable to similar-level excutives at
Novellus and which are consistent with Novellus' past hiring practices.

Indemnification

     For not less than (i) six (6) years, in the case of certain acts and
omissions, and (ii) four (4) years, for all other acts or omissions, after the
effective time of the merger, Novellus will, and will cause GaSonics as the
surviving corporation in the merger to, indemnify and hold harmless the present
and former officers, directors, employees and agents of GaSonics (the
"Indemnified Parties") in respect of acts or omissions occurring on or prior to
- --------------------
the effective time of the merger to the extent provided for under GaSonics'
Certificate of Incorporation and Bylaws and existing indemnification agreements,
subject to any limitation imposed from time to time under applicable law.

     For (i) six (6) years, in the case of certain acts and omissions, and (ii)
four (4) years, for all other acts or omissions after the effective time of the
merger, Novellus will, and will cause GaSonics as the surviving corporation in
the merger to, use its best efforts to provide officers' and directors'
liability insurance in respect of acts or omissions occurring on or prior to the
effective time of the merger covering each such person currently covered by
GaSonics' officers' and directors' liability insurance policy on terms at least
as favorable as the coverage currently in effect on the date hereof. Novellus
will not be obligated to cause the surviving corporation to pay premiums in
excess of 150% of the amount per annum GaSonics paid in its last full fiscal
year. If the surviving corporation is unable to obtain the required insurance
without paying more than that, it will obtain as much comparable insurance as
possible at that cost.

     For a period of (i) six (6) years, in the case of certain acts and
omissions, and (ii) four (4) years, for all other acts or omissions, after the
effective time, to the extent there is any claim, action, suit, proceeding or
investigation (whether commencing before or after the effective time) against or
involving any indemnified party that arises out of or pertains to any action or
omission (or alleged action or omission) in his or her capacity as a director,
officer, employee, or agent of GaSonics which act omission occurred prior to the
effective time, Novellus will, and will cause the surviving corporation to,
provide legal counsel and to defend the indemnified party and to pay the
reasonable fees and expenses of counsel.

     Novellus will also pay all expenses, including reasonable attorneys' fees,
that may be incurred by any Indemnified Party in enforcing the indemnity and
other obligations provided for in the merger agreement to the extent that the
indemnified party is determined to be entitled to indemnification under the
merger agreement.

     Forward-Looking Statements:  Except for the historical information
     ---------------------------
presented, certain matters discussed in this press release are forward-looking
statements that are subject to certain risks and uncertainties that could cause
actual results to differ materially from any future results, performance or
achievements expressed or implied by such statements.  Forward-looking
statements in this release include statements regarding financial forecasts,
market growth predictions, leadership positions,  bringing new technologies and
products to the market, and the likelihood and timing of closing.  Factors that
could cause actual results to differ materially include risks and uncertainties
such as the failure of GaSonics' technology to complement and/or broaden
Novellus' current technologies, the ability of the combined company to create
anticipated synergies and increased product sales as a result of the
acquisition,  and possible difficulties in combining the operating plans and
scientific cultures of Novellus and GaSonics.  These risks are detailed from
time to time in Novellus' and GaSonics' public disclosure filings with the U.S.
Securities and Exchange Commission (SEC), including Novellus' annual report on
Form 10-K for the fiscal year ended December 31, 1999, Novellus' Quarterly
