                            ________________________

 
  This Prospectus relates to $115,000,000 aggregate principal amount of 6 1/4%
Convertible Subordinated Notes due September 15, 2004 (the "Notes") of
Integrated Process Equipment Corp. (the "Company") under the Securities Act of
1933, as amended (the "Securities Act"), and the shares of Common Stock, $.001
par value of the Company, ("Common Stock") issuable upon the conversion of the
Notes (the "Conversion Shares").  The Notes registered hereby were issued and
sold on September 17, 1997 (the "Original Offering") in transactions exempt from
the registration requirements of the Securities Act to persons reasonably
believed by Morgan Stanley & Co. Incorporated, Hambrecht & Quist LLC, Prudential
Securities Incorporated and UBS Securities LLC as the initial purchasers (the
"Initial Purchasers") of the Notes to be "qualified institutional buyers" (as
defined by Rule 144A under the Securities Act) or other institutional
"accredited investors" (as defined in Rule 501(a)(1), (2), (3) or (7) under
Regulation D of the Securities Act). The Notes and the Common Stock issuable
upon conversion thereof may be offered, and sold from time to time by the
holders named herein or by their transferees, pledgees, donees or their
successors (collectively, the "Selling Securityholders") pursuant to this
Prospectus. The Registration Statement of which this Prospectus is a part has
been filed with the Securities and Exchange Commission (the "Commission")
pursuant to a registration rights agreement dated as of September 15, 1997 (the
"Registration Rights Agreement") between the Company and the Initial Purchasers,
entered into in connection with the Original Offering.

  The Notes are convertible at the option of the holder into shares of Common
Stock of the Company (at any time on or after December 17, 1997 and prior to
redemption or maturity, at a conversion rate of 25.6410 shares per $1,000
principal amount of  Notes), subject to adjustment under certain circumstances.
Interest on the Notes is payable semi-annually in arrears on March 15 and
September 15 of each year, commencing on March 15, 1998.  

     
  Prior to the registration of the Notes under the Registration Statement, the
Notes have been designated for trading on The PORTAL Market. Notes sold pursuant
to this Prospectus are not eligible for trading on The PORTAL Market. Prior to 
this offering there has been no public market for the Notes. On February 5,
1998, the closing price of the Common Stock, which is quoted on the Nasdaq
National Market under the symbol "IPEC," was $14 3/4 per share.     

                            _______________________

                 THE NOTES AND THE COMMON STOCK OFFERED HEREBY
               INVOLVE A HIGH DEGREE OF RISK.  SEE "RISK FACTORS"
                             COMMENCING ON PAGE 7.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES

ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY REPRESENTATION TO THE CONTRARY IS
A CRIMINAL OFFENSE.

  The Notes are unsecured general obligations of the Company and are
subordinated in right of payment to all existing and future Senior Indebtedness
(as defined in the Indenture).  See "Description of Notes -- Subordination."
The Notes will mature on September 15, 2004, and may be redeemed, at the option
of the Company, in whole or in part, at any time on or after September 20, 2000
at the redemption prices set forth herein plus accrued interest.  Each holder of
Notes will have the right to cause the Company to redeem all of such holder's
Notes, in the event of a Fundamental Change (as defined in the Indenture) that
occurs at any time prior to September 15, 2004.

  The Notes and the Conversion Shares may be offered by the Selling
Securityholders from time to time in transactions (which may include block
transactions in the case of the Conversion Shares) on any exchange or market on
which such securities are listed or quoted, as applicable, in negotiated
transactions, through a combination of such methods of sale, or otherwise, at
fixed prices that may be changed, at market prices prevailing at the time of
sale, at prices related to prevailing market prices or at negotiated prices.
The Selling Securityholders may effect such transactions by selling the Notes or
Conversion Shares directly or to or through broker-dealers, who may receive
compensation in the form of discounts, concessions or commissions from the
Selling Securityholders and/or the purchasers of the Notes or Conversion Shares
for whom such broker-dealers may act as agents or to whom they may sell as
principals, or both (which compensation as to a particular broker-dealer might
be in excess of customary commissions).  The Company will not receive any of the
proceeds from the sale of the Notes or Conversion Shares by the Selling
Securityholders.  The Company has agreed to pay all expenses incident to the
offer and sale of the Notes and Conversion Shares offered by the Selling
Securityholders hereby, except that the Selling Securityholders will pay all
underwriting discounts and selling commissions, if any.  See "Plan of
Distribution."

<S>                       <C>
Securities Offered........$115,000,000 aggregate principal amount of 6 1/4%
                                Convertible Subordinated Notes due 2004 (the
                                "Notes") issued under an Indenture dated as of
                                September 15, 1997 (the "Indenture") between the
                                Company and State Street Bank and Trust Company
                                of California N.A. as trustee (the "Trustee"),
                                and Common Stock issuable upon conversion
                                thereof.
Interest Payment Dates....March 15 and September 15, commencing March 15, 1998.

Conversion................The Notes are convertible at the option of the holder
                                at any time on or after December 17, 1997,
                                unless previously redeemed, into Common Stock at
                                a conversion price of $39 per share, subject to
                                adjustment in certain events.
    
Subordination.............The Notes are subordinated to all existing and future
                                Senior Indebtedness (as defined) and effectively
                                subordinated to all liabilities, including trade
                                payables and lease obligations, if any, of the
                                Company's subsidiaries. The issuer of the Notes
                                is a holding company with no significant
                                operating assets, and its ability to make
                                payments on the Notes is dependent on
                                distributions from its subsidiaries. As of
                                December 31, 1997, the Company had
                                approximately $4.4 million of indebtedness
                                outstanding that would have constituted Senior
                                Indebtedness, and the Company's subsidiaries had
                                approximately $34.5 million of indebtedness and
                                other liabilities outstanding (excluding
                                liabilities of a type not required to be
                                reflected on a balance sheet in accordance with
                                generally accepted accounting principles and
                                intercompany liabilities) to which the Notes
                                would have been effectively subordinated. The
                                Indenture does not limit the amount of
                                indebtedness, including Senior Indebtedness,
                                that the Company may incur or the amount of
                                indebtedness or other liabilities that the
                                Company's subsidiaries may incur.     

Redemption................The Notes are not redeemable by the Company prior to
                                September 20, 2000. Subject to the foregoing,
                                the Notes will be redeemable on at least 30
                                days' notice at the option of the Company, in
                                whole or in part, at any time, at the redemption
                                prices set forth in "Description of Notes,"
                                together with accrued interest.

Fundamental Change........Upon the occurrence of any Fundamental Change (as
                                defined) prior to the maturity of the Notes,
                                each holder shall have the right, at such
                                holder's option, to require the Company to
                                redeem all or any part of such holder's Notes at
                                the redemption prices set forth in "Description
                                of Notes," together with accrued interest.

Use of Proceeds...........The Company will not receive any of the proceeds from
                                sale of the Notes or the Common Stock issuable
                                upon conversion thereof.

Registration Rights.......Upon any failure by the Company to comply with certain
                                of its obligations under the Registration Rights
                                Agreement, certain predetermined liquidated
                                damages will be payable by the Company to those
                                holders of the Notes and those holders of Common
                                Stock issued upon conversion of the Notes who
                                have requested to sell pursuant to the
                                Registration Statement.

                                  RISK FACTORS

     This Prospectus contains or incorporates by reference forward-looking
     ---------------------------------------------------------------------
statements that involve risks and uncertainties. The statements contained or
- ----------------------------------------------------------------------------
incorporated by reference in this Prospectus that are not purely historical are
- -------------------------------------------------------------------------------
forward-looking statements within the meaning of Section 27A of the Securities
- ------------------------------------------------------------------------------
Act of 1933 and Section 21E of the Securities Exchange Act of 1934, including
- -----------------------------------------------------------------------------
without limitation statements regarding the Company's expectations, beliefs,
- ---------------------------------------------------------------------------
intentions or strategies regarding the future. All forward-looking statements
- -----------------------------------------------------------------------------
included in this document are based on information available to the Company on
- ------------------------------------------------------------------------------
the date hereof, and all forward-looking statements incorporated by reference
- -----------------------------------------------------------------------------
are based on information available to the Company as of the date of such
- ------------------------------------------------------------------------
documents. The Company assumes no obligation to update any such forward-looking
- -------------------------------------------------------------------------------
statements. The Company's actual results could differ materially from those
- ---------------------------------------------------------------------------
anticipated in these forward-looking statements as a result of certain factors,
- ------------------------------------------------------------------------------
including those set forth in the following risk factors and elsewhere in this
- -----------------------------------------------------------------------------
Prospectus and other documents incorporated by reference. In evaluating the
- ---------------------------------------------------------------------------
Company's business, prospective investors should consider carefully the
- -----------------------------------------------------------------------
following factors in addition to the other information presented in this
- ------------------------------------------------------------------------
Prospectus.
- ----------

     The Factors Affecting Operating Results contained in the Company's
Quarterly Report on Form 10-Q filed with the Commission for the quarter ended
September 30, 1997 are incorporated herein by this reference.  These risk
factors include the Company's limited operating history, potential delays in
significant shipments and orders, dependence on a small number of major
customer, the need for broader acceptance of the Company's products,
technological changes, intense competition, reliance on the Asian market, and
difficulties in defending and securing intellectual property rights for the
Company's products.

    
     The Notes are Unsecured and Subordinated to Senior Indebtedness and Do Not
     --------------------------------------------------------------------------
Contain Financial Covenants. The Notes are unsecured and subordinated in right
- ---------------------------
of payment in full to all existing and future Senior Indebtedness (as defined)
of the Company. As a result of such subordination, in the event of bankruptcy,
liquidation or reorganization of the Company or upon acceleration of the Notes
due to an Event of Default under the Indenture and in certain other events, the
assets of the Company will be available to pay obligations on the Notes only
after all Senior Indebtedness has been paid in full, and there may not be
sufficient assets remaining to pay amounts due on any or all of the Notes then
outstanding. The Company's existing credit facility contains detailed financial
covenants. The Company and the lender from time to time in the past have amended
the Company's financial covenants when, absent the amendment, the Company would
not have been in compliance with the covenants. There can be no assurance as to
the ability of the Company to comply with these and other covenants associated
with Senior Indebtedness in the future, and the Company's inability to do so
could result in the blockage of interest or other payments on the Notes pending
the cure of such default and/or in the acceleration of such Senior Indebtedness.
The Indenture does not contain financial covenants or prohibit or limit the
incurrence of Senior Indebtedness or the incurrence of other indebtedness and
other liabilities by the Company, and the incurrence of additional indebtedness
and other liabilities by the Company could adversely affect the Company's
ability to pay its obligations on the Notes. As of December 31, 1997, the
Company had approximately $4.4 million of indebtedness outstanding that would
have constituted Senior Indebtedness. The Company anticipates that from time to
time it will incur significant amounts of additional indebtedness, including
Senior Indebtedness. See "Description of Notes-Subordination of Notes."     

     IPEC's Holding Company Structure May Affect its Ability to Make Payments on
     ---------------------------------------------------------------------------
the Notes and Results in Substantial Structural Subordination. The issuer of the
- -------------------------------------------------------------
Notes is a holding company with no significant operating assets. The Company's
ability to redeem, repurchase or make interest and principal payments on the
Notes is dependent upon the earnings of its subsidiaries and the distribution of
those earnings (through dividends or otherwise) to, or upon royalties, license
fees, loans or other payment of funds by those subsidiaries to, the Company. The
subsidiaries are separate and distinct legal entities and have no 

                                      -7-
<PAGE>
 
obligation, contingent or otherwise, to pay any amounts due pursuant to the
Notes or to make any funds available therefor, whether by dividends, loans or
other payments. In addition, the payment of dividends and the making of loans
and advances to the Company by its subsidiaries may be subject to statutory,
contractual or other restrictions and are dependent upon the earnings or
financial condition of those subsidiaries and subject to various business
considerations. As a result, IPEC may be unable to gain access to the cash flow
or assets of its subsidiaries in amounts sufficient to pay the principal of or
interest on the Notes when due or to redeem Notes at the option of the holders
thereof after the occurrence of a Fundamental Change.

    
     The Notes are effectively subordinated to the liabilities, including trade
payables and lease obligations, if any, of the subsidiaries of the Company. Any
right of the Company to receive the assets of any of its subsidiaries upon the
liquidation or reorganization thereof (and the consequent right of the holders
of the Notes to participate in those assets) will be effectively subordinated to
the claims of that subsidiary's creditors (including trade creditors), except to
the extent that the Company is itself recognized as a creditor of such
subsidiary, in which case the claims of the Company would still be subordinate
to any security interests in the assets of such subsidiary and any indebtedness
of such subsidiary senior to that held by the Company. The Indenture does not
prohibit or limit the incurrence of indebtedness and other liabilities by any
subsidiary of the Company, and the incurrence of additional indebtedness and
other liabilities by any subsidiary of the Company could adversely affect the
Company's ability to pay its obligations on the Notes. As of December 31, 1997,
the Company's subsidiaries had approximately $34.5 million of indebtedness and
other liabilities outstanding (excluding liabilities of a type not required to
be reflected on a balance sheet in accordance with generally accepted accounting
principles and intercompany liabilities) to which the Notes would have been
effectively subordinated. The Company anticipates that from time to time its
subsidiaries will incur significant amounts of additional indebtedness and other
liabilities. See "Description of Notes-Subordination of Notes."     

     The Notes are Subject to Limitations on Redemption Upon a Fundamental
     ---------------------------------------------------------------------
Change. Upon a Fundamental Change (as defined), each holder of the Notes will
- ------
have certain rights, at the holder's option, to require the Company to redeem
all or a portion of such holder's Notes. If a Fundamental Change were to occur,
there can be no assurance that the Company would have sufficient funds to pay
the redemption price for all the Notes tendered by the holders thereof. In
addition, the terms of the Company's existing credit facility prohibit the
Company from purchasing or redeeming any Notes and also provide that a
Fundamental Change would constitute an event of default thereunder. Any future
credit agreements or other agreements relating to other indebtedness (including
other Senior Indebtedness) to which the Company becomes a party may contain
similar restrictions and provisions. In the event a Fundamental Change occurs at
a time when the Company is prohibited from purchasing or redeeming the Notes,
the Company could seek the consent of its lenders to the purchase of the Notes
or could attempt to refinance the borrowings that contain such prohibition. If
the Company does not obtain such a consent or repay such borrowings, the Company
would remain prohibited from purchasing or redeeming the Notes. In such case,
the Company's failure to redeem tendered Notes would constitute an Event of
Default under the Indenture, which would, in turn, constitute a further default
under the Company's existing credit facility and may constitute a default under
the terms of other indebtedness that the Company may enter into from time to
time. In such circumstances, the subordination provisions in the Indenture would
likely restrict payments to the holders of Notes. The term "Fundamental Change"
is limited to certain specified transactions and may not include other events
that might adversely affect the financial condition of the Company. The
requirement that the Company redeem the Notes upon a Fundamental Change may not
afford holders of the Notes protection in the event of a highly leveraged
transaction, reorganization, merger or similar transaction involving the
Company. See "Description of Notes-Redemption at Option of the Holder."

     Limited Public Market Exists for the Notes. The Company does not intend
     ------------------------------------------
to list the Notes on any national securities exchange or to seek the admission
thereof to trading in the Nasdaq system. The Initial Purchasers

                                      -8-
<PAGE>
 
may make a market in the Notes and the underlying Common Stock. However, the
Initial Purchasers are not obligated to make such a market and may discontinue
any market-making activities at any time without notice. In addition, such
market-making activities are subject to the limits imposed by the Securities Act
and the Exchange Act. Although prior to the registration of the Notes under the
Registration Statement the Notes were designated for trading through The PORTAL
Market, the Notes sold hereunder will no longer be eligible for trading through
The PORTAL Market, and no assurance can be given that an active trading market
for the Notes will develop or, if such market develops, as to the liquidity or
sustainability of such market. If a trading market does not develop or is not
maintained, holders of the Notes may experience difficulty in reselling, or an
inability to sell, the Notes. If a market for the Notes develops, any such
market may be discontinued at any time. If a public trading market develops for
the Notes, future trading prices of the Notes will depend on many factors,
including, among other things, prevailing interest rates, the Company's
operating results and the market for similar securities. Depending on prevailing
interest rates, the market for similar securities and other factors, including
the financial condition of the Company, the Notes may trade at a discount from
the principal amount. See "--The Company's Common Stock Price and The Price of
The Notes Are Volatile."

    
     The Company's Common Stock Price and the Price of the Notes are Volatile.
     ------------------------------------------------------------------------
The market price of the Company's Common Stock has been, and may continue to be,
extremely volatile. The market price of the Notes and the shares of Common Stock
into which the Notes are convertible may be significantly affected by factors
such as quarter-to-quarter variations in the actual or anticipated financial
results of the Company or of other companies in the semiconductor industry, or
in the markets served by the Company, announcements by the Company or its
competitors regarding new product introductions, changes in financial estimates
by securities analysts, changes in prevailing interest rates, general market
conditions, and other factors. In addition, the stock market has experienced
extreme price and volume fluctuations that have particularly affected the market
price for many high technology companies and that have often been unrelated to
the operating performance of these companies. The market price of the Company's
Common Stock has fluctuated substantially in recent periods, from a low of $9-
1/2 on July 16, 1996 to a high of $37-11/16 on October 1, 1997. On February 5,
1998, the reported last sale price of the Company's Common Stock on the Nasdaq
National Market was $14 3/4. These broad market fluctuations may adversely
affect the market price of the Notes and the Common Stock into which the Notes
are convertible, and there can be no assurance that the market price of the
Notes and the Common Stock into which the Notes are convertible will not decline
below the levels prevailing at the time of this offering. In the past, following
periods of volatility in the market price of a particular company's securities,
securities class action litigation has often been brought against that company.
Such litigation, if brought against the Company, could result in substantial
costs and a diversion of management's attention and resources.

expense incurred, amortization of debt expense and the portion of rental expense
under leases deemed by the Company to be representative of the interest factor.
For the years ended June 30, 1993, 1994, 1996 and 1997, earnings were
insufficient to cover fixed charges by $2,599, $9,730, $15,762 and $8,133,
respectively.


                                USE OF PROCEEDS

     The Company will not receive any of the proceeds from the sale of the Notes
or the Common Stock issuable upon conversion thereof by the Selling
Securityholders.

                              DESCRIPTION OF NOTES

     The Notes were initially issued by the Company under an indenture dated as
of September 15, 1997 (the "Indenture"), between the Company and State Street
Bank and Trust Company of California, N.A., as trustee (the "Trustee"). The
Indenture and the Registration Rights Agreement were filed as exhibits to the
Company's Quarterly Report on Form 10-Q for reporting date September 30, 1997
and filed on November 13, 1997. The following summaries of certain provisions of
the Notes, the Indenture and the Registration Rights Agreement do not purport to
be complete and are subject to, and are qualified in their entirety by reference
to, all the provisions of the Notes, the Indenture and the Registration Rights
Agreement, including the definitions therein of certain terms which are not
otherwise defined in this Prospectus. Wherever particular provisions or defined
terms of the Indenture (or of the form of Note which is a part thereof) or the
Registration Rights Agreement are referred to, such provisions or defined terms
are incorporated herein by reference. References in this section to the
"Company" are solely to Integrated Process Equipment Corp., a Delaware
corporation, and not its subsidiaries.

GENERAL

     The Notes represent unsecured general obligations of the Company
subordinate in right of payment to certain other obligations of the Company as
described under "Subordination of Notes" and convertible into Common Stock as
described under "Conversion of Notes." The Notes are limited to $115,000,000
aggregate principal amount, are issued only in denominations of $1,000 and
multiples thereof and will mature on September 15, 2004 unless earlier redeemed
at the option of the Company or at the option of the holder upon a Fundamental
Change (as defined).

     The Indenture does not contain any financial covenants or restrictions on
the payment of dividends, the incurrence of Senior Indebtedness (as defined
below under "Subordination of Notes") or the issuance or repurchase of
securities of the Company.  The Indenture contains no covenants or other
provisions to afford protection to holders of the Notes in the event of a highly
leveraged transaction or a change in control of the Company except to the extent
described under "Redemption at Option of the Holder."

     The Notes bear interest at the annual rate set forth on the cover page
hereof from September 17, 1997, payable semi-annually on March 15 and September
15, commencing on March 15, 1998, to holders of record at the close of business
on the preceding March 1 and September 1, respectively, except (i) that the
interest payable upon redemption (unless the date of redemption is an interest
payment date) will be payable to the person to whom principal is payable and
(ii) as set forth in the next succeeding sentence.  In the case of any Note (or
portion thereof) which is converted into Common Stock of the Company during the
period from (but excluding) a record date to (but excluding) the next succeeding
interest payment date either (i) if such Note (or portion thereof) has been
called for redemption on a redemption date which occurs during such period, or
is to be redeemed in connection with a Fundamental Change on a Repurchase Date
(as defined) which occurs during such period, the Company shall not be required
to pay interest on such interest payment date in respect of any such Note (or
portion thereof) or (ii) if otherwise, any Note (or portion thereof) submitted
for conversion during such period shall be accompanied by funds equal to the
interest payable on such succeeding interest payment date on the principal
amount so converted (see "Conversion of Notes").  Interest may, at the Company's
option, be paid either (i) by check mailed to the address of the person entitled
thereto as it appears in the Note register or (ii) by transfer to an account
maintained by such person located in the United States; provided, however, that
payments to The Depository Trust Company, New York, New York ("DTC") will be
made by wire transfer of immediately available funds to the account of DTC or
its nominee.  Interest will be computed on the basis of a 360-day year composed
of twelve 30-day months.

     The Company does not intend to list the Notes on any national securities 
exchange or to seek the admission thereof to trading in the Nasdaq system. The 
Initial Purchasers may make a market in the Notes and the underlying Common 
Stock. However, the Initial Purchasers are not obligated to make such a market 
and may discontinue any market-making activities at any time without notice. In 
addition, such market-making activities are subject to limits imposed by the 
Exchange Act.

     Although prior to the registration of the Notes under the Registration 
Statement the Notes were designated for trading through The PORTAL Market, the 
Notes sold hereunder will no longer be eligible for trading through The PORTAL 
Market, and no assurance can be given that an active trading market for the 
Notes will develop or, if such market develops, as to the liquidity or 
sustainability of such market. If a trading market does not develop or is not 
maintained, holders of the Notes may experience difficulty in reselling, or an 
inability to sell, the Notes. If a market for the Notes develops, any such 
market may be discontinued at any time. If a public trading market develops for 
the Notes, future trading prices of the Notes will depend on many factors, 
including, among other things, prevailing interest rates, the Company's 
operating results and the market for similiar securities. Depending on 
prevailing interest rates, the market for similar securities and other factors, 
including the financial condition of the Company, the Notes may trade at a 
discount from their principal amount. See "Risk Factors -- The Company's Common 
Stock and the Price of the Notes are Volatile."

CONVERSION OF NOTES

     The holders of Notes will be entitled at any time after 90 days following
the date of original issuance thereof through the close of business on
the final maturity date of the Notes, subject to prior redemption, to convert
any Notes or portions thereof (in denominations of $1,000 or multiples thereof)
into Common Stock of the Company, at the conversion price set forth on the cover
page of this Prospectus, subject to adjustment as described below.  Except as
described below, no payment or other adjustment will be made on conversion of
any Notes for interest accrued thereon or for dividends on any Common Stock
issued.  If any Notes not called for redemption are converted after a record
date for the payment of interest and prior to the next succeeding interest
payment date, such Notes must be accompanied by funds equal to the interest
payable on such succeeding interest payment date on the principal amount so
converted.  The Company is not required to issue fractional shares of Common
Stock upon conversion of Notes and, in lieu thereof, will pay a cash adjustment
based upon the market price of Common Stock on the last business day prior to
the date of conversion.  In the case of Notes called for redemption, conversion
rights will expire at the close of business on the business day preceding the
day fixed for redemption unless the Company defaults in the payment of the
redemption price.  A Note in respect of which a holder is exercising its option

                                      -14-
<PAGE>
 
to require redemption upon a Fundamental Change may be converted only if such
holder withdraws its election to exercise its option in accordance with the
terms of the Indenture.

     The initial conversion price of $39 per share of Common Stock is subject to
adjustment under formulae as set forth in the Indenture in certain events,
including:

           (i)    the issuance of Common Stock of the Company as a dividend or
     distribution on the Common Stock;

           (ii)   certain subdivisions and combinations of the Common Stock;

           (iii)  the issuance to all holders of Common Stock of certain rights
     or warrants to purchase Common Stock;

           (iv)   the distribution to all holders of Common Stock of capital
     stock (other than Common Stock) or evidences of indebtedness of the Company
     or of assets (including securities, but excluding those rights, warrants,
     dividends and distributions referred to above or paid in cash);

           (v)    distributions consisting of cash, excluding any quarterly cash
     dividend on the Common Stock to the extent that the aggregate cash dividend
     per share of Common Stock in any quarter does not exceed the greater of (x)
     the amount per share of Common Stock of the next preceding quarterly cash
     dividend on the Common Stock to the extent that such preceding quarterly
     dividend did not require an adjustment of the conversion price pursuant to
     this clause (v) (as adjusted to reflect subdivisions or combinations of the
     Common Stock), and (y) 3.75 percent of the average of the last reported
     sales price of the Common Stock during the ten trading days immediately
     prior to the date of declaration of such dividend, and excluding any
     dividend or distribution in connection with the liquidation, dissolution or
     winding up of the Company.  If an adjustment is required to be made as set
     forth in this clause (v) as a result of a distribution that is a quarterly
     dividend, such adjustment would be based upon the amount by which such
     distribution exceeds the amount of the quarterly cash dividend permitted to
     be excluded pursuant to this clause (v).  If an adjustment is required to
     be made as set forth in this clause (v) as a result of a distribution that
     is not a quarterly dividend, such adjustment would be based upon the full
     amount of the distribution;

           (vi)   payment in respect of a tender offer or exchange offer by the
     Company or any subsidiary of the Company for the Common Stock to the extent
     that the cash and value of any other consideration included in such payment
     per share of Common Stock exceeds the Current Market Price (as defined in
     the Indenture) per share of Common Stock on the trading day next succeeding
     the last date on which tenders or exchanges may be made pursuant to such
     tender or exchange offer; and

           (vii)  payment in respect of a tender offer or exchange offer by a
     person other than the Company or any Subsidiary (as defined in the
     Indenture) of the Company in which, as of the closing date of the offer,
     the Board of Directors is not recommending rejection of the offer.  The
     adjustment referred to in this clause (vii) will only be made if the tender
     offer or exchange offer is for an amount that increases the offeror's
     ownership of Common Stock to more than 25% of the total shares of Common
     Stock outstanding, and if the cash and value of any other consideration
     included in such payment per share of Common Stock exceeds the Current
     Market Price per share of Common Stock on the business day next succeeding
     the last date on which tenders or exchanges may be made pursuant to such
     tender or exchange offer.  The adjustment referred to in this clause (vii)
     will 

                                      -15-
<PAGE>
 
     generally not be made, however, if, as of the closing of the offer, the
     offering documents with respect to such offer disclose a plan or an
     intention to cause the Company to engage in a consolidation or merger of
     the Company or a sale of all or substantially all of the Company's assets.

     Under the terms of the Company's stockholder rights plan, upon conversion
of the Notes into Common Stock, to the extent the stockholder rights plan is
still in effect upon such conversion, the holders of such Notes will receive, in
addition to the Common Stock, the rights described therein (whether or not the
rights have separated from the Common Stock at the time of the conversion),
subject to certain limited exceptions. 

     In the case of (i) any reclassification of the Common Stock or (ii) a
consolidation, merger or combination involving the Company or a sale or
conveyance to another person of the property and assets of the Company as an
entirety or substantially as an entirety, in each case as a result of which
holders of Common Stock shall be entitled to receive stock, other securities,
other property or assets (including cash) with respect to or in exchange for
such Common Stock, the holders of the Notes then outstanding will generally be
entitled thereafter to convert such Notes into the kind and amount of shares of
stock, other securities or other property or assets which they would have owned
or been entitled to receive upon such reclassification, consolidation, merger,
combination, sale or conveyance had such Notes been converted into Common Stock
immediately prior to such reclassification, consolidation, merger, combination,
sale or conveyance assuming that a holder of Notes would not have exercised any
rights of election as to the stock, other securities or other property or assets
receivable in connection therewith.

     In the event of a taxable distribution to holders of Common Stock or in
certain other circumstances requiring conversion price adjustments, the holders
of Notes may, in certain circumstances, be deemed to have received a
distribution subject to United States income tax as a dividend; in certain other
circumstances, the absence of such an adjustment may result in a taxable
dividend to the holders of Common Stock. See "Certain Federal Income Tax
Considerations."

     The Company from time to time may to the extent permitted by law reduce the
conversion price by any amount for any period of at least 20 days, in which case
the Company shall give at least 15 days' notice of such reduction, if the Board
of Directors has made a determination that such reduction would be in the best
interests of the Company, which determination shall be conclusive.  The Company
may, at its option, make such reductions in the conversion price, in addition to
those set forth above, as the Board of Directors deems advisable to avoid or
diminish any income tax to holders of Common Stock resulting from any dividend
or distribution of stock (or rights to acquire stock) or from any event treated
as such for income tax purposes. See "Certain Federal Income Tax
Considerations."

     No adjustment in the conversion price will be required unless such
adjustment would require a change of at least 1% in the conversion price then in
effect; provided that any adjustment that would otherwise be required to be made
shall be carried forward and taken into account in any subsequent adjustment.
Except as stated above, the conversion price will not be adjusted for the
issuance of Common Stock or any securities convertible into or exchangeable for
Common Stock or carrying the right to purchase any of the foregoing.

OPTIONAL REDEMPTION BY THE COMPANY

     The Notes are not entitled to any sinking fund.  At any time on or after
September 20, 2000, the Notes will be redeemable at the Company's option on at
least 30 days' notice as a whole or, from time to time, in part at the following
prices (expressed as a percentage of the principal amount), together with
accrued interest to, but excluding, the date fixed for redemption:

                                      -16-

     If redeemed during the period beginning September 20, 2000 and ending on
September 14, 2001 at a redemption price of 103.571%, and if redeemed during the
12-month period beginning September 15:

and 100% at September 15, 2004; provided that any semi-annual payment of
interest becoming due on the date fixed for redemption shall be payable to the
holders of record on the relevant record date of the Notes being redeemed.

     If less than all of the outstanding Notes are to be redeemed, the Trustee
shall select the Notes to be redeemed in principal amounts of $1,000 or
multiples thereof by lot, pro rata or by another method the Trustee considers
fair and appropriate.  If a portion of a holder's Notes is selected for partial
redemption and such holder converts a portion of such Notes, such converted
portion shall be deemed to be of the portion selected for redemption.

     The Company may not give notice of any redemption of Notes if a default in
payment of interest or premium on the Notes or any other Event of Default has
occurred and is continuing.

REDEMPTION AT OPTION OF THE HOLDER

     If a Fundamental Change (as defined) occurs at any time prior to September
15, 2004, each holder of Notes shall have the right, at the holder's option, to
require the Company to redeem any or all of such holder's Notes on the date (the
"Repurchase Date") that is 30 days after the date of the Company's notice of
such Fundamental Change.  The Notes will be redeemable in multiples of $1,000
principal amount.

     The Company shall redeem such Notes at a price expressed as a percentage of
the principal amount equal to (i) 106.250% if the Repurchase Date is before
September 15, 1998, (ii) 105.357% if the Repurchase Date is during the 12-month
period beginning September 15, 1998, (iii) 104.464% if the Repurchase Date is
during the period beginning September 15, 1999 and ending on September 19, 2000
and (iv) thereafter at the redemption price set forth under "Optional Redemption
by the Company" which would be applicable to a redemption at the option of the
Company on the Repurchase Date; provided that, if the Applicable Price (as
defined in the Indenture) is less than the Reference Market Price (as defined in
the Indenture), the Company shall redeem such Notes at a price equal to the
foregoing redemption price multiplied by the fraction obtained by dividing the
Applicable Price by the Reference Market Price.  In each case, the Company shall
also pay accrued interest on the redeemed Notes to, but excluding, the
Repurchase Date; provided that, if such Repurchase Date is an interest payment
date, then the interest payable on such date shall be paid to the holder of
record of the Notes on the relevant record date.

     The Company is required to mail to all holders of record of the Notes a
notice of the occurrence of a Fundamental Change and of the redemption right
arising as a result thereof on or before the tenth day after the occurrence of
such Fundamental Change.  The Company is also required to deliver the Trustee a
copy of such notice.  To exercise the redemption right, a holder of Notes must
deliver, on or before the 30th day after the date of the Company's notice of a
Fundamental Change (the "Fundamental Change Expiration Time"), written notice of
the holder's exercise of such right, together with the Notes to be so redeemed,
duly endorsed for transfer, to the Company (or an agent designated by the
Company for such purpose).  Payment 

                                      -17-
<PAGE>
 
for Notes surrendered for redemption (and not withdrawn) prior to the
Fundamental Change Expiration Time will be made promptly following the
Repurchase Date.

     The term "Fundamental Change" means the occurrence of any transaction or
event in connection with which all or substantially all Common Stock shall be
exchanged for, be converted into, be acquired for, or constitute in all material
respects solely the right to receive, consideration which is not all of
substantially all common stock listed (or, upon consummation of or immediately
following such transaction or event, which will be listed) on a United States
national securities exchange or approved for quotation on the Nasdaq National
Market or any similar United States system of automated dissemination of
quotations of securities prices (whether by means of an exchange offer,
liquidation, tender offer, consolidation, merger, combination, reclassification,
recapitalization or otherwise).  The term "Applicable Price" means (i) in the
event of a Fundamental Change in which the holders of the Common Stock receive
only cash, the amount of cash received by the holder of one share of Common
Stock and (ii) in the event of any other Fundamental Change, the average of the
last reported sale price for the Common Stock during the ten trading days prior
to the record date for the determination of the holders of Common Stock entitled
to receive cash, securities, property or other assets in connection with such
Fundamental Change, or, if there is no such record date, the date upon which the
holders of the Common Stock shall have the right to receive such cash,
securities, property or other assets in connection with the Fundamental Change.
The term "Reference Market Price" shall initially mean $20 (which is equal to
662/3% of the last bid price of the Common Stock as reflected on the cover page
of this Prospectus) and in the event of any adjustment to the conversion price
described above pursuant to the provisions of the Indenture, the Reference
Market Price shall also be adjusted so that the ratio of the Reference Market
Price to the conversion price after giving effect to any such adjustment shall
always be the same as the ratio of $20 to the conversion price specified on the
cover page of this Prospectus (without regards to any adjustment thereto).

     The Company will comply with the provisions of Rule 13e-4 and any other
tender offer rules under the Exchange Act to the extent then applicable in
connection with the redemption rights of the holders of Notes in the event of a
Fundamental Change.

     The redemption rights of the holders of Notes could discourage a potential
acquiror of the Company. The Fundamental Change redemption feature, however, is
not the result of management's knowledge of any specific effort to obtain
control of the Company by means of a merger, tender offer, solicitation or
otherwise, or part of a plan by management to adopt a series of anti-takeover
provisions.  The term "Fundamental Change" is limited to certain specified
transactions and may not include other events that might adversely affect the
financial condition of the Company, nor would the requirement that the Company
offer to repurchase the Notes upon a Fundamental Change necessarily afford the
holders of the Notes protection in the event of a highly leveraged transaction,
reorganization, merger or similar transaction involving the Company.

     If a Fundamental Change were to occur, there can be no assurance that the
Company would have sufficient funds to pay the redemption price for all the
Notes tendered by the holders thereof.  In addition, the terms of the Company's
existing credit facility prohibit the Company from purchasing or redeeming any
Notes and also provide that a Fundamental Change would constitute an event of
default thereunder.  Any future credit agreements or other agreements relating
to other indebtedness (including other Senior Indebtedness) to which the Company
becomes a party may contain similar restrictions and provisions.  In the event a
Fundamental Change occurs at a time when the Company is prohibited from
purchasing or redeeming the Notes, the Company could seek the consent of its
lenders to the purchase of the Notes or could attempt to refinance the
borrowings that contain such prohibition.  If the Company does not obtain such a
consent or repay such borrowings, the Company would remain prohibited from
purchasing or redeeming the Notes.  In such case, the Company's failure to
redeem tendered Notes would constitute an Event of Default 

                                      -18-
<PAGE>
 
under the Indenture, which would, in turn, constitute a further default under
the Company's existing credit facility and may constitute a default under the
terms of other indebtedness that the Company may enter into from time to time.
In such circumstances, the subordination provisions in the Indenture would
likely restrict payments to the holders of Notes. The term "Fundamental Change"
is limited to certain specified transactions and may not include other events
that might adversely affect the financial condition of the Company.

SUBORDINATION OF NOTES

     The Indebtedness evidenced by the Notes is subordinated to the extent
provided in the Indenture to the prior payment in full of all Senior
Indebtedness of the Company.  The Notes also are effectively subordinated to all
indebtedness and other liabilities, including trade payables and lease
obligations, if any, of the Company's subsidiaries.

     Upon any distribution of assets of the Company upon any dissolution,
winding up, liquidation or reorganization, the payment of the principal of, or
premium, if any, and interest (including liquidated damages, if any) on the
Notes is to be subordinated to the extent provided in the Indenture in right of
payment to the prior payment in full in cash of all Senior Indebtedness.  In the
event of any acceleration of the Notes because of an Event of Default (as
defined in the Indenture), the holders of any Senior Indebtedness then
outstanding would be entitled to payment in full in cash of all obligations in
respect of such Senior Indebtedness before the holders of the Notes are entitled
to receive any payment or distribution in respect thereof.  The Indenture
requires that the Company promptly notify holders of Senior Indebtedness if
payment of the Notes is accelerated because of an Event of Default.

     The Company also may not make any payment upon or in respect of the Notes
(including upon redemption) if (i) a default in the payment of the principal,
premium, if any, interest, rent or other obligations in respect of Senior
Indebtedness occurs and is continuing beyond any applicable period of grace (a
"Payment Default") or (ii) any other default occurs and is continuing with
respect to Designated Senior Indebtedness (as defined) that permits holders of
such Designated Senior Indebtedness to accelerate its maturity and the Trustee
receives a notice of such default (a "Payment Blockage Notice") from the Company
or other person permitted to give such notice under the Indenture (a "Non-
Payment Default").  Payments on the Notes may and shall be resumed (a) in case
of a Payment Default, upon the date on which such default is cured or waived or
ceases to exist and (b) in case of a Non-Payment Default, the earlier of the
date on which such Non-Payment Default is cured or waived or ceases to exist or
179 days after the date on which the applicable Payment Blockage Notice is
received.  No new period of payment blockage may be commenced pursuant to a
Payment Blockage Notice unless and until (i) 365 days have elapsed since the
initial effectiveness of the immediately prior Payment Blockage Notice and (ii)
all scheduled payments of principal, premium, if any, and interest (including
liquidated damages, if any) on the Notes that have come due have been paid in
full in cash.  No Non-Payment Default that existed or was continuing on the date
of delivery of any Payment Blockage Notice to the Trustee shall be, or shall be
made, the basis for a subsequent Payment Blockage Notice.

     In the event that, notwithstanding the foregoing, the Trustee or any holder
of the Notes receives any payment or distribution of assets of the Company of
any kind in contravention of any of the subordination provisions of the
Indenture, whether in cash, property or securities, including, without
limitation, by way of set-off or otherwise, in respect of the Notes before all
Senior Indebtedness is paid in full, then such payment or distribution will be
held by the recipient in trust for the benefit of holders of Senior Indebtedness
or their representatives to the extent necessary to make payment in full of all
Senior Indebtedness remaining unpaid, after giving effect to any concurrent
payment or distribution, or provision therefor, to or for the holders of Senior
Indebtedness.

                                      -19-
<PAGE>
 
     By reason of the subordination provisions described above, in the event of
the Company's bankruptcy, dissolution or reorganization, holders of Senior
Indebtedness may receive more, ratably, and holders of the Notes may receive
less, ratably, than the other creditors of the Company.  Such subordination will
not prevent the occurrence of any Event of Default under the Indenture.

     The term "Senior Indebtedness" means the principal of, premium, if any,
interest (including all interest accruing subsequent to the commencement of any
bankruptcy or similar proceeding, whether or not a claim for post-petition
interest is allowable as a claim in any such proceeding) and rent payable on or
in connection with, and all fees, costs, expenses and other amounts accrued or
due on or in connection with, Indebtedness (as defined) of the Company, whether
outstanding on the date of the Indenture or thereafter created, incurred,
assumed, guaranteed or in effect guaranteed by the Company (including all
deferrals, renewals, extensions or refundings of, or amendments, modifications
or supplements to, the foregoing), unless in the case of any particular
Indebtedness the instrument creating or evidencing the same or the assumption or
guarantee thereof expressly provides that such Indebtedness shall not be senior
in right of payment to the Notes or expressly provides that such Indebtedness is
pari passu or junior to the Notes. Notwithstanding the foregoing, the term
Senior Indebtedness shall not include Indebtedness of the Company to any
subsidiary of the Company, a majority of the voting stock of which is owned,
directly or indirectly, by the Company.

     The term "Indebtedness" means, with respect to any Person (as defined) and
without duplication:

          (a) all indebtedness, obligations and other liabilities (contingent or
     otherwise) of such Person for borrowed money (including obligations of the
     Company in respect of overdrafts, foreign exchange contracts, currency
     exchange agreements, interest rate protection agreements, and any loans or
     advances from banks, whether or not evidenced by notes or similar
     instruments) or evidenced by bonds, debentures, notes or similar
     instruments (whether or not the recourse of the lender is to the whole of
     the assets of such Person or to only a portion thereof), other than any
     account payable or other accrued current liability or obligation incurred
     in the ordinary course of business in connection with the obtaining of
     materials or services;

          (b) all reimbursement obligations and other liabilities (contingent or
     otherwise) of such Person with respect to letters of credit, bank
     guarantees or bankers' acceptances;

          (c) all obligations and liabilities (contingent or otherwise) in
     respect of leases of such Person required, in conformity with generally
     accepted accounting principles, to be accounted for as capitalized lease
     obligations on the balance sheet of such Person and all obligations and
     other liabilities (contingent or otherwise) under any lease or related
     document (including a purchase agreement) in connection with the lease of
     real property which provides that such Person is contractually obligated to
     purchase or cause a third party to purchase the leased property and thereby
     guarantee a minimum residual value of the leased property to the lessor and
     the obligations of such Person under such lease or related document to
     purchase or to cause a third party to purchase such leased property;

          (d) all obligations of such Person (contingent or otherwise) with
     respect to an interest rate or other swap, cap or collar agreement or other
     similar instrument or agreement or foreign currency hedge, exchange,
     purchase or similar instrument or agreement;

          (e) all direct or indirect guaranties or similar agreements by such
     Person in respect of, and obligations or liabilities (contingent or
     otherwise) of such Person to purchase or otherwise 

                                      -20-
<PAGE>
 
     acquire or otherwise assure a creditor against loss in respect of,
     indebtedness, obligations or liabilities of another Person of the kind
     described in clauses (a) through (d);

          (f) any indebtedness or other obligations described in clauses (a)
     through (d) secured by any mortgage, pledge, lien or other encumbrance
     existing on property which is owned or held by such Person, regardless of
     whether the indebtedness or other obligation secured thereby shall have
     been assumed by such Person; and

          (g) any and all deferrals, renewals, extensions and refundings of, or
     amendments, modifications or supplements to, any indebtedness, obligation
     or liability of the kind described in clauses (a) through (f).

     The term "Designated Senior Indebtedness" means Senior Indebtedness under
the Company's existing revolving credit facility or any other particular Senior
Indebtedness in which the instrument creating or evidencing the same or the
assumption or guarantee thereof (or related agreements or documents to which the
Company is a party) expressly provides that such Senior Indebtedness shall be
"Designated Senior Indebtedness" for purposes of the Indenture (provided that
                                                                --------
such instrument, agreement or other document may place limitations and
conditions on the right of such Senior Indebtedness to exercise the rights of
Designated Senior Indebtedness).

     The Notes are also effectively subordinated to all liabilities, including
trade payables and lease obligations, if any, of the Company's subsidiaries.
Any right of the Company to receive the assets of any of its subsidiaries upon
the liquidation or reorganization thereof (and the consequent right of the
holders of the Notes to participate in those assets) will be effectively
subordinated to the claims of that subsidiary's creditors (including trade
creditors), except to the extent that the Company is itself recognized as a
creditor of such subsidiary, in which case the claims of the Company would still
be subordinate to any security interests in the assets of such subsidiary and
any indebtedness of such subsidiary senior to that held by the Company.

     The Company is a holding company with no significant operating assets.  The
Company's ability to redeem, repurchase or make interest and principal payments
on the Notes is dependent upon the earnings of its subsidiaries and the
distribution of those earnings (through dividends or otherwise) to, or upon
royalties, license fees, loans or other payment of funds by those subsidiaries
to, the Company.  The subsidiaries are separate and distinct legal entities and
have no obligation, contingent or otherwise, to pay any amounts due pursuant to
the Notes or to make any funds available therefor, whether by dividends, loans
or other payments.  In addition, the payment of dividends and the making of
loans and advances to the Company by its subsidiaries may be subject to
statutory, contractual or other restrictions and are dependent upon the earnings
or financial condition of those subsidiaries and subject to various business
considerations.  As a result, the Company may be unable to gain access to the
cash flow or assets of its subsidiaries in amounts sufficient to pay the
principal of or interest on the Notes when due or to redeem Notes at the option
of the holders thereof after the occurrence of a Fundamental Change.

    
     As of December 31, 1997, the Company had approximately $4.4 million of
indebtedness outstanding that would have constituted Senior Indebtedness, and
the Company's subsidiaries had approximately $34.5 million of indebtedness and
other liabilities outstanding (other than liabilities of a type not required to
be reflected in a balance sheet in accordance with generally accepted accounting
principles and intercompany indebtedness) to which the Notes would have been
effectively subordinated.  The Indenture does not limit the amount of additional
indebtedness, including Senior Indebtedness, which the Company can create,
incur, assume or guarantee, nor does the Indenture limit the amount of
indebtedness or other liabilities that any subsidiary can create, incur, assume
or guarantee.     

                                      -21-
<PAGE>
 
     The Company is obligated to pay reasonable compensation to the Trustee and
to indemnify the Trustee against certain losses, liabilities or expenses
incurred by it in connection with its duties relating to the Notes.  The
Trustee's claims for such payments will generally be senior to those of the
holders of the Notes in respect of all funds collected or held by the Trustee.

EVENTS OF DEFAULT; NOTICE AND WAVIER

     An Event of Default is defined in the Indenture as being: default in
payment of the principal of or premium, if any (upon redemption or otherwise),
on the Notes (whether or not such payment is permitted to be made under the
subordination provisions described above); default for 30 days in payment of any
installment of interest (including liquidated damages, if any) on the Notes
(whether or not such payment is permitted to be made under the subordination
provisions described above); default by the Company for 60 days after notice in
the observance or performance of any other covenants in the Indenture; or
certain events involving bankruptcy, insolvency or reorganization of the Company
or any of its Significant Subsidiaries (as defined in the Indenture).  The
Indenture provides that the Trustee may withhold notice to the holders of the
Notes of any default (except in payment of principal or premium, if any, or
interest (including liquidated damages, if any) with respect to the Notes) if
the Trustee considers it in the interest of the holders of the Notes to do so.

     The Indenture provides that if an Event of Default shall have occurred and
be continuing, the Trustee or the holders of not less than 25% in principal
amount of the Notes then outstanding may declare the principal of, premium, if
any, and accrued interest (including liquidated damages, if any) on the Notes to
be due and payable immediately.  In the case of certain events of bankruptcy or
insolvency of the Company, the principal of, premium, if any, and accrued
interest (including liquidated damages, if any) on the Notes shall automatically
become and be immediately due and payable.  However, if the Company shall cure
all defaults (except the nonpayment of principal of, premium, if any, and
interest (including liquidated damages, if any) on any of the Notes which shall
have become due by acceleration) and certain other conditions are met, with
certain exceptions, such declaration may be canceled and past defaults may be
waived by the holders of a majority of the principal amount of the Notes then
outstanding.

     The Indenture provides that any payment of principal, premium, if any, or
interest (including liquidated damages, if any) that is not made when due
(whether or not such payment is permitted to be made under the subordination
provisions described above) will accrue interest, to the extent legally
permissible, at the annual rate set forth on the cover page hereof from the date
on which such payment was required under the terms of the Indenture until the
date of payment.

     The holders of a majority in principal amount of the Notes then outstanding
shall have the right to direct the time, method and place of conducting any
proceedings for any remedy available to the Trustee, subject to certain
limitations specified in the Indenture.

     The Indenture provides that no holder of the Notes may pursue any remedy
under the Indenture, except for a default in the payment of principal, premium,
if any (including upon redemption), or interest (including liquidated damages,
if any), on the Notes, unless such holder shall have previously given to the
Trustee written notice of a continuing Event of Default, and the holders of at
least 25% in principal amount of the outstanding Notes shall have made a written
request, and offered reasonable indemnity, to the Trustee to pursue the remedy,
and the Trustee shall not have received from the holders of a majority in
principal amount of the outstanding Notes a direction inconsistent with such
request and shall have failed to comply with such request within 60 days after
receipt of such request.

                                      -22-
<PAGE>
 
MODIFICATION OF THE INDENTURE

     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the holders of a majority in principal amount of the Notes
at the time outstanding, to modify the Indenture or any supplemental indenture
or the rights of the holders of the Notes, except that no such modification
shall (i) extend the fixed maturity of any Note, reduce the rate or extend the
time for payment of interest thereon, reduce the principal amount thereof or
premium, if any, thereon, reduce any amount payable upon redemption thereof,
change the obligation of the Company to redeem any Note upon the happening of
any Fundamental Change in a manner adverse to the holders of the Notes, impair
the right of a holder to institute suit for the payment thereof, change the
currency in which the Notes are payable, impair the right to convert the Notes
into Common Stock subject to the terms set forth in the Indenture, or modify the
provisions of the Indenture with respect to the subordination of the Notes in a
manner adverse to the holders of the Notes in any material respect, without the
consent of each holder of a Note so affected or (ii) reduce the aforesaid
percentage of Notes whose holders are required to consent to any such
modification of the Indenture or any such supplemental indenture, in each case
without the consent of the holders of all of the Notes then outstanding.  The
Indenture also provides for certain modifications of its terms without the
consent of the holders of the Notes.

REGISTRATION RIGHTS OF THE NOTEHOLDERS

     The Company has agreed to file with the Commission a shelf registration
statement (of which this Prospectus is a part) (the "Shelf Registration
Statement") covering resales by holders of the Notes and the Common Stock
issuable upon conversion of the Notes within 90 days after the date of original
issuance of the Notes. The Company has agreed to use reasonable efforts to cause
the Shelf Registration Statement to become effective as promptly as is
practicable and to keep the Shelf Registration Statement effective until the
earlier of (i) the sale pursuant to the Shelf Registration Statement of all the
securities registered thereunder and (ii) the expiration of the holding period
applicable to such securities pursuant to Rule 144(k) under the Securities Act
or any successor provision. The Company will be permitted to suspend the use of
this Prospectus for a period not to exceed 30 days in any three-month period, or
not to exceed an aggregate of 60 days in any 12-month period under certain
circumstances relating to pending corporate developments, public filings with
the Commission and similar events. The Company has agreed to pay predetermined
liquidated damages to those holders of Notes and those holders of Common Stock
issued upon conversion of the Notes who have requested to sell pursuant to the
Shelf Registration Statement if the Shelf Registration Statement was not timely
filed or if the Prospectus is unavailable for periods in excess of those
permitted above. The Company has further agreed, if such failure to file or
unavailability continues for an additional 30-day period, to pay predetermined
liquidated damages to all holders of Notes and all holders of Common Stock
issued upon conversion of the Notes, whether or not such holder has requested to
sell pursuant to the Shelf Registration Statement. A holder who sells the Notes
or the Common Stock issued upon conversion of the Notes pursuant to the Shelf
Registration Statement generally will be required to be named as a selling
stockholder in the related prospectus, deliver a prospectus to purchasers and be
bound by those provisions of the Registration Rights Agreement which are
applicable to such holder (including certain indemnification provisions). The
Company will pay all expenses of the Shelf Registration Statement, provide to

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

     The following is a summary of certain United States federal income tax
considerations relating to the purchase, ownership and disposition of the Notes
and of Common Stock into which Notes may be converted, but does not purport to
be a complete analysis of all the potential tax considerations relating thereto.
This summary is based on laws, regulations, rulings and decisions now in effect,
all of which are subject to change.  This summary deals only with holders that
will hold Notes and Common Stock into which Notes may be converted as "capital
assets" (within the meaning of Section 1221 of the Internal Revenue Code of
1986, as amended (the "Code")) and does not address tax considerations
applicable to investors that may be subject to special tax rules, such as banks,
tax-exempt organizations, insurance companies, foreign persons, dealers in
securities or currencies, persons that will hold Notes as a position in a
hedging transaction, "straddle" or "conversion transaction" for tax purposes or
persons deemed to sell Notes or Common Stock under the recently enacted
constructive sale provisions of the Code.  This summary discusses the tax
considerations applicable to the initial purchasers of the Notes who purchase
the Notes at their "issue price" as defined in Section 1273 of the Code and does
not discuss the tax considerations applicable to subsequent purchasers of the
Notes.  The Company has not sought any ruling from the Internal Revenue Service
(the "IRS") with respect to the statements made and the conclusions reached in
the following summary, and there can be no assurance that the IRS will agree
with such statements and conclusions.  In addition, the IRS is not precluded
from successfully adopting a contrary position.  This summary does not consider
the effect of any applicable foreign, state, local or other tax laws.

     INVESTORS CONSIDERING THE PURCHASE OF NOTES SHOULD CONSULT THEIR OWN TAX
ADVISORS WITH RESPECT TO THE APPLICATION OF THE UNITED STATES FEDERAL INCOME TAX
LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES ARISING
UNDER THE LAWS OF ANY STATE, LOCAL OR FOREIGN TAXING JURISDICTION OR UNDER ANY
APPLICABLE TAX TREATY.

TAXATION OF INTEREST

     Interest paid on the Notes will be included in the income of a holder as
ordinary income at the time it is treated as received or accrued, in accordance
with the holder's regular method of tax accounting.  Failure of the Company to
file or cause to be declared effective a shelf registration statement as
described under "Description of Notes--Registration Rights of the Noteholders"
may result in the payment of predetermined liquidated damages in the manner
described therein, which payments will be treated as additional interest on the
Notes.  According to Treasury Regulations, the possibility of a change in the
interest rate will not affect the amount of interest income recognized by a
holder (or the timing of such recognition) if the likelihood of the change, as
of the date the Notes are issued, is remote.  The Company believes that the
likelihood of a change in the interest rate on the Notes is remote and does not
intend to treat the possibility of a change in the interest rate as affecting
the yield to maturity of any Note.  Similarly, the Company intends to take the
position that a "Fundamental Change" is remote under the Treasury Regulations,
and likewise does not intend to treat the possibility of a "Fundamental Change"
as affecting the yield to maturity of any Note.

SALE, EXCHANGE OR REDEMPTION OF THE NOTES

     Upon the sale, exchange or redemption of a Note, a holder generally will
recognize capital gain or loss equal to the difference between (i) the amount of
cash proceeds and the fair market value of any property received on the sale,
exchange or redemption (except to the extent such amount is attributable to
accrued interest income not previously included in income which is taxable as
ordinary income) and (ii) such holder's adjusted tax basis in the Note.  A
holder's adjusted tax basis in a Note generally will equal the cost of the 

                                      -25-
<PAGE>
 
Note to such holder. Such capital gain or loss will be long-term capital gain or
loss if the holder's holding period in the Note is more than one year at the
time of sale, exchange or redemption. Under recently enacted legislation, long-
term capital gains will generally be subject to a maximum rate of tax of 28% on
property held more than one year, and a maximum rate of tax of 20% on property
held more than 18 months.

CONVERSION OF THE NOTES

     A holder generally will not recognize any income, gain or loss upon
conversion of a Note into Common Stock except to the extent the Common Stock is
considered attributable to accrued interest not previously included in income
(which is taxable as ordinary income) or with respect to cash received in lieu
of a fractional Share of Common Stock.  A holder's tax basis in the Common Stock
received on conversion of a Note will be the same as such holder's adjusted tax
basis in the Note at the time of conversion (reduced by any basis allocable to a
fractional share interest), and the holding period for the Common Stock received
on conversion will generally include the holding period of the Note converted.
However, a holder's tax basis in shares of Common Stock considered attributable
to accrued interest as described above generally will equal the amount of such
accrued interest included in income, and the holding period for such shares
shall begin on the date of conversion.

     Cash received in lieu of a fractional share of Common Stock upon conversion
will be treated as a payment in exchange for the fractional share of Common
Stock.  Accordingly, the receipt of cash in lieu of a fractional share of Common
Stock generally will result in capital gain or loss (measured by the difference
between the cash received for the fractional share and the holder's adjusted tax
basis in the fractional share).

DIVIDENDS

     Dividends paid on the Common Stock generally will be includable in the
income of a holder as ordinary income to the extent of the Company's current or
accumulated earnings and profits.

     Holders of convertible debt instruments such as the Notes may, in certain
circumstances, be deemed to have received constructive distributions where the
conversion ratio of such instruments is adjusted. Adjustments to the conversion
price made pursuant to a bona fide reasonable adjustment formula which has the
effect of preventing the dilution of the interest of the holders of the debt
instruments, however, will generally not be considered to result in a
constructive distribution of stock.  Certain of the possible adjustments
provided in the Notes (including, without limitation, adjustments in respect of
taxable dividends to stockholders of the Company) will not qualify as being
pursuant to a bona fide reasonable adjustment formula.  If such adjustments are
made, the holders of Notes might be deemed to have received constructive
distributions taxable as dividends.

SALE OF COMMON STOCK

     Upon the sale or exchange of Common Stock, a holder generally will
recognize capital gain or loss equal to the difference between (i) the amount of
cash and the fair market value of any property received upon the sale or
exchange and (ii) such holder's adjusted tax basis in the Common Stock.  Such
capital gain or loss will be long-term capital gain or loss if the holder's
holding period in Common Stock is more than one year at the time of the sale or
exchange.  Under recently enacted legislation, long-term capital gains will
generally be subject to a maximum rate of tax of 28% on property held more than
one year, and a maximum rate of tax of 20% on property held more than 18
months.  A holder's basis and holding period in Common Stock received upon
conversion of a Note are determined as discussed above under "Conversion of the
Notes."

                                      -26-

INFORMATION REPORTING AND BACKUP WITHHOLDING TAX

     In general, information reporting requirements will apply to payments of
principal, premium, if any, and interest on a Note, payments of dividends on
Common Stock, payments of the proceeds of the sale of a Note and payments of the
proceeds of the sale of Common Stock, and a 31% backup withholding tax may apply
to such payments if the holder either (i) fails to demonstrate that the holder
comes within certain exempt categories of holders or (ii) fails to furnish or
certify his correct taxpayer identification number to the payor in the manner
required, is notified by the IRS that he has failed to report payments of
interest and dividends properly, or under certain circumstances, fails to
certify that he has not been notified by the IRS that he is subject to backup
withholding for failure to report interest and dividend payments.  Any amounts
withheld under the backup withholding rules from a payment to a holder will be
allowed as a credit against such holder's United States federal income tax and
may entitle the holder to a refund, provided that the required information is
furnished to the IRS.

(1)  Includes shares of Common Stock issuable upon conversion of the Notes.

(2)  Assumes a conversion price of $39.00 per share, and a cash payment in lieu
     of any fractional share interest; such conversion price is subject to
     adjustment as described under "Description of Notes -- Conversion."
     Accordingly, the number of shares of Common Stock issuable upon conversion
     of the Notes may increase or decrease from time to time.  Under the terms
     of Indenture, fractional shares will not be issued upon conversion of the
     Notes; cash will be paid in lieu of fractional shares, if any.

(3)  Information concerning other Selling Securityholders will be set forth in
     Prospectus Supplements from time to time, if required.

                                      -29-

(4)  Assumes that any other holders of Notes or any future transferee from any
     such holder does not beneficially own any Common Stock other than the
     Common Stock issuable upon conversion of the Notes at the initial
     conversion rate.


     The Notes offered hereby were originally issued by the Company and sold by
the Initial Purchasers, in a transaction exempt from the registration
requirements of the Securities Act, to persons reasonably believed by such
Initial Purchasers to be "qualified institutional buyers" (as defined in Rule
144A under the Securities Act) or other institutional "accredited investors" (as
defined in Rule 501(a)(1), (2), (3) or (7) under Regulation D of the Securities
Act).  The Selling Securityholders (which term includes their transferees,
pledgees, donees or their successors) may from time to time offer and sell
pursuant to this Prospectus any or all of the Notes and Common Stock issued upon
conversion of the Notes.

     The Selling Securityholders identified above may have sold, transferred or
otherwise disposed of, in transactions exempt from the registration requirements
of the Securities Act, all or a portion of their notes since the date on which
the information in the preceding table is presented.  Information concerning the
Selling Securityholders may change from time to time and any such changed
information will be set forth in supplements to this Prospectus if and when
necessary.  Because the Selling Securityholders may offer all or some of the
Notes that they hold and/or the common stock issuable upon conversion thereof
pursuant to the offering contemplated by this Prospectus, no estimate can be
given as to the amount of the Notes or the Common Stock issuable upon conversion
thereof that will be held by the Selling Securityholders upon the termination of
any such sales. In addition, the Selling Securityholders identified above may
have sold, transferred or otherwise disposed of all or a portion of their Notes
since the date on which they provided the information regarding their Notes in
transactions exempt from the registration requirements of the Securities Act. 
See "Plan of Distribution."

     Information concerning the Selling Securityholders may change from time to
time and any such changed information will be set forth in supplements to this
Prospectus if and when necessary.  In addition, the per share conversion price,
and therefore the number of shares issuable upon conversion of the Notes, is
subject to adjustment under certain circumstances. Accordingly, the aggregate
principal amount of Notes and the number of shares of common stock issuable upon
conversion thereof offered hereby may increase or decrease.

     From time to time, Morgan Stanley & Co. Incorporated, Hambrecht & Quist
LLC, Prudential Securities Incorporated and UBS Securities LLC have provided,
and continue to provide, investment banking services to the Company, for which
they received or will receive customer fees.  None of the other Selling
Securityholders has had any position, office or other material relationship with
the Company or its affiliates within the last three years.


     The Company will pay the expenses of registering the Notes and Common Stock
being sold hereunder.

                              PLAN OF DISTRIBUTION

     The Company will not receive any of the proceeds of the sale of the Notes
and Common Stock offered hereby. The Notes and Common Stock may be sold from
time to time to purchasers directly by the Selling Securityholders.
Alternatively, the Selling Securityholders may from time to time offer the Notes
and Common Stock through brokers, dealers or agents who may receive compensation
in the form of discounts, concessions or commissions from the Selling
Securityholders and/or the purchasers of the Notes and Common Stock for whom
they may act as agent. The Selling Securityholders and any such brokers, dealers
or agents who participate in the distribution of the Notes and Common Stock may
be deemed to be "underwriters," and any profits on the sale of the Notes and
Common Stock by them and any discounts, commissions or concessions received by
any such brokers, dealers or agents might be deemed to be underwriting discounts
and commissions under the Securities Act. To the extent the Selling
Securityholders may be deemed to be underwriters, the Selling Securityholders
may be subject to certain statutory liabilities of, including, but not limited
to, Sections 11, 12 and 17 of the Securities Act and Rule 10b-5 under the
Exchange Act.

     The Notes and Common Stock offered hereby may be sold from time to time in
one or more transactions at fixed prices, at prevailing market prices at the
time of sale, at varying prices determined at the time of sale or at negotiated
prices. The Notes and Common Stock may be sold by one or more of the following
methods, without limitation: (a) a block trade in which the broker or dealer so
engaged will attempt to sell the Notes and Common Stock as agent but may
position and resell a portion of the block as principal to facilitate the
transaction; (b) purchases by a broker or dealer as principal and resale by such
broker or dealer for its account pursuant to this Prospectus; (c) ordinary
brokerage transactions and transactions in which the broker solicits purchasers;
(d) an exchange distribution in accordance with the rules of such exchange; (e)
face-to-face transactions between sellers and purchasers without a broker-
dealer; and (f) through the writing of options. At any time a particular offer
of the Notes and Common Stock is made, a revised Prospectus or Prospectus
Supplement, if required, will be distributed which will set forth the aggregate
amount and type of securities being offered and the terms of the offering,
including the name or names of any underwriters, dealers or agents, any
discounts, commissions, concessions and other items constituting compensation
from the Selling Securityholders and any discounts, commissions or concessions
allowed or reallowed or paid to dealers. Such Prospectus Supplement and, if
necessary, a post-effective amendment to the Registration Statement of which
this Prospectus is a part, will be filed with the Commission to reflect the
disclosure of additional information with respect to the distribution of the
Notes and Common Stock. In addition, the Notes and Common Stock covered by this
Prospectus may be sold in private transactions or under Rule 144 rather than
pursuant to this Prospectus.

     To the best knowledge of the Company, there are currently no plans,
arrangement or understandings between any Selling Securityholders and any
broker, dealer, agent or underwriter regarding the sale of the Notes and Common
Stock by the Selling Securityholders. There is no assurance that any Selling
Securityholder will sell any or all of the Notes and Common Stock offered by it
hereunder or that any such Selling Securityholder will not transfer, devise or
gift such Notes and Common Stock by other means not described herein.

     The Selling Securityholders and any other person participating in such
distribution will be subject to applicable provisions of the Exchange Act and
the rules and regulations thereunder, including, without limitation, Regulation
M, which may limit the timing of purchases and sales of any of the Notes and
Common Stock by the Selling Securityholders and any other such person.
Furthermore, Regulation M of the Exchange Act may restrict the ability of any
person engaged in the distribution of the Notes and Common Stock to engage in
market-making activities with respect to the particular Notes and Common Stock
being distributed for a period of up to five business days prior to the
commencement of such distribution. All of 

                                      -31-
<PAGE>
 
the foregoing may affect the marketability of the Notes and Common Stock and the
ability of any person or entity to engage in market-making activities with
respect to the Notes and Common Stock.

     Pursuant to the Registration Rights Agreement entered into in connection
with the offer and sale of the Notes by the Company, each of the Company and the
Selling Securityholders will be indemnified by the other against certain
liabilities, including certain liabilities under the Securities Act, or will be
entitled to contribution in connection therewith.

     The Company has agreed to pay substantially all of the expenses incidental
to the registration, offering and sale of the Notes and Common Stock to the
public other than commissions, fees and discounts of underwriters, brokers,
dealers and agents.

                                 LEGAL MATTERS

     The validity of the issuance of the Notes and the underlying Common Stock
offered hereby has been passed upon for the Company by Wilson Sonsini Goodrich &

ITEM 14.  EXPENSES OF ISSUANCE AND DISTRIBUTION.

     The following table sets forth the various expenses payable by the
Registrant in connection with the sale and distribution of the securities being
registered hereby.  Normal commission expenses and brokerage fees are payable
individually by the Selling Securityholders.  All amounts are estimated except
the Securities and Exchange Commission registration fee.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law 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 such indemnification under
certain circumstances for liabilities (including reimbursement for expenses
incurred) arising under the Securities Act.  The Company's Certificate of
Incorporation, as amended, and the Bylaws, as amended, provide for
indemnification of its directors, officers, employees and other agents to the
maximum extent permitted by the Delaware General Corporation law.  In addition,
the Company has entered into Indemnification Agreements with its officers and
directors.  The Company also currently maintains an officers' and directors'
liability insurance policy  which insures, subject to the exclusions and
limitations of the policy, officers and directors of the Company against certain
liabilities which might be incurred by them solely in such capacities.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling the registrant
pursuant to the foregoing provisions, the registrant has been informed that in
the opinion of the Commission such indemnification is against public policy as
expressed in the Securities Act and is therefore unenforceable.

ITEM 17.  UNDERTAKINGS.

     The undersigned Registrant hereby undertakes:

     (1)        To file, during any period in which offers or sales are being
                made, a post-effective amendment to the Registration Statement
                to include any material information with respect to the plan of
                distribution not previously disclosed in the Registration
                Statement or any material change to such information in the
                Registration Statement.

     (2)        That, for the purpose 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.

     (3)        To remove from registration by means of a post-effective
                amendment any of the securities being registered which remain
                unsold at the termination of the offering.

     The undersigned registrant hereby undertakes 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
Exchange Act that is incorporated by reference in the 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 the initial bona fide offering thereof.

     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 foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable.  In the event that such 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.

  RE: REGISTRATION STATEMENT ON FORM S-3
      ----------------------------------

Gentlemen:

  We have examined the Registration Statement on Form S-3 to be filed by
Integrated Process Equipment Corp. (the "Company") with the Securities and
Exchange Commission on or about December 15, 1997 (the "Registration
Statement"), in connection with the registration under the Securities Act of
1933, as amended, of shares of Common Stock of the Company (the "Shares")
issuable upon conversion of $115,000,000 aggregate principal amount of 6-1/4%
Convertible Subordinated Notes (the "Registrable Notes") of the Company due
September 15, 2004.

     
  It is our opinion that:     
        
     1. The Registrable Notes are valid and binding obligations of the Company
        enforceable in accordance with their terms, subject to applicable
        bankruptcy or similar laws affecting creditors' rights generally and
        general principles of equity.     
        
     2. Upon completion of the proceedings being taken or contemplated by us, as
        your counsel, to be taken prior to the issuance of Shares, the Shares,
        when issued and sold in the manner referred to in the Registration
        Statement and in accordance with the terms of the Registrable Notes,
        will be legally and validly issued, fully paid and nonassessable.     

  We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to all references to us in the Registration
Statement, the Prospectus constituting a part thereof and any amendments thereto
which have been approved by us.

                                         Very truly yours,
