     4.1    Indenture, dated as of August 6, 1997, by and among Cymer, Inc. and
            State Street Bank and Trust Company of California, N.A., as trustee
            thereunder.
     4.2    Registration Rights Agreement, dated as of August 6, 1997, by and

            Montgomery Securities.



ITEM 9.        Sale of Equity Securities Pursuant to the Regulation S.

          On August 6, 1997, Cymer, Inc., a Nevada corporation (the
"Company"), completed the sale of $172,500,000 aggregate principal amount of its
3 1/2%/7 1/4% Step-up Convertible Subordinated Notes due 2004 (the "Notes").
Interest on the Notes will accrue at the rate per annum of 3 1/2% for August 6,
1997 through August 5, 2000 and at the rate per annum of 7 1/4% from August 6,
2000 to maturity and is payable semi-annually on February 6 and August 6 of each
year, commencing on February 6, 1998. The Notes are convertible, in whole or in
part, at the option of the holder at any time from and after November 4, 1997
through maturity, unless previously redeemed, into shares of the Company's
Common Stock, at a conversion price of $94.00 per share, subject to adjustment 
in certain circumstances. The Notes are redeemable at the Company's option at 
any time from and after August 9, 2000 at the redemption prices specified 
therein, together with accrued interest. Moreover, if a "Fundamental Change" 
(as defined in the Indenture for the Notes) of the Company were to occur prior 
to maturity, each holder of Notes would be entitled to require the Company to 
purchase its Notes, in whole or in part, at a purchase price specified therein,
together with accrued interest. No sinking fund is provided for the Notes, 
which are general unsecured obligations of the Company, subordinated in right 
of payment to all "Senior Indebtedness" (as defined in the Indenture for the 
Notes) of the Company and effectively subordinated in right of payment to the 
prior payment in full of all indebtedness and other liabilities of the 
Company's subsidiaries.

          The Notes were sold by the Company to Morgan Stanley & Co.
Incorporated and Montgomery Securities, as initial purchasers (collectively, the
"Initial Purchasers"), in an unregistered private placement conducted pursuant
to Section 4(2) of the Securities Act of 1933, as amended (the "Securities
Act"). The discount to the Initial Purchasers was 3% of the principal amount of
the Notes purchased (or an aggregate of $5,175,000).

          The Company has been advised that the Initial Purchasers subsequently
resold the Notes in the United States to "qualified institutional buyers" in
reliance on Rule 144A under the Securities Act and outside of the United States
in offshore transactions to investors in reliance on Regulation S under the
Securities Act. In addition, the Company has been advised that the Initial
Purchasers have resold a portion of the Notes in the United States to a limited
number of institutions that are "accredited investors" within the meaning of
Rule 501(a)(1), (2), (3) or (7) under the Securities Act.

          The Company has agreed to file, within 90 days following the last
original issue date of the Notes, a shelf registration statement in respect of
Common Stock issuable upon conversion of the Notes, pursuant to a Registration
Rights Agreement dated as of August 6, 1997, by and among the Company and the
Initial Purchasers.

          The foregoing summary of the Notes, the Indenture and the Registration
Rights Agreement does not purport to be complete and is subject to, and
qualified in its entirety by reference to, all of the provisions of the Notes,
the Indenture and Registration Rights Agreement, forms of which are filed as
Exhibits to this Current Report on Form 8-K (included in the Indenture in the
case of the form of Note).
