Borrowing Date and (iii) the respective lengths of the initial Interest Period
therefor. Each borrowing under the Revolving Commitments shall be in an amount
equal to E500,000 or a whole multiple of E100,000 in excess thereof. Upon
receipt of any such notice, the Administrative Agent shall promptly notify each
Lender thereof. Each Lender will make the amount of its pro rata share of each
borrowing available to the Administrative Agent for the account of the relevant
Borrower at the Funding Office prior to 12:00 Noon, London time, on the
Borrowing Date requested by the relevant Borrower in funds immediately available
to the Administrative Agent. Such borrowing will then be made available to the

available to the Administrative Agent by the Lenders and in like funds as
received by the Administrative Agent.

            2.3   Commitment Fees, etc.

            (a) GMBH agrees to pay to the Administrative Agent for the account
of each relevant Lender a commitment fee for the period from and including the
date hereof to the last day of the Revolving Commitment Period, computed at the
Commitment Fee Rate on the average daily amount of the Available GMBH Revolving
Commitment of such Lender during the period for which payment is made, payable
quarterly in arrears on each Fee Payment Date, commencing on the first such date
to occur after the date hereof. BV agrees to pay to the Administrative Agent for
the account of each relevant Lender a commitment fee for the period from and
including the date hereof to the last day of the Revolving Commitment Period,
computed at the Commitment Fee Rate on the average daily amount of the Available
BV Revolving Commitment of such Lender during the period for which payment is
made, payable quarterly in arrears on each Fee Payment Date, commencing on the
first such date to occur after the date hereof.

            (b) Novellus agrees to pay to the Administrative Agent the fees in
the amounts and on the dates as set forth in any fee agreements with the
Administrative Agent and to perform any other obligations contained therein.

            2.4   Termination or Reduction of Revolving Commitments.

            (a) GMBH shall have the right, upon not less than three Business
Days' notice to the Administrative Agent, to terminate the GMBH Revolving
Commitments or, from time to time, to reduce the amount of the GMBH Revolving
Commitments; provided that no such termination or reduction of GMBH Revolving
Commitments shall be permitted if, after giving effect thereto and to any
prepayments by GMBH of the Revolving Loans made on the effective date thereof,
the Total GMBH Revolving Extensions of Credit would exceed the Total GMBH
Revolving Commitments. Any such reduction shall be in an amount equal to
E500,000, or a whole multiple thereof, and shall reduce permanently the GMBH
Revolving Commitments then in effect.

            (b) BV shall have the right, upon not less than three Business Days'
notice to the Administrative Agent, to terminate the BV Revolving Commitments
or, from time to time, to reduce the amount of the BV Revolving Commitments;
provided that no such termination or reduction of BV Revolving Commitments shall
be permitted if, after giving effect thereto and to any prepayments by BV of the
Revolving Loans made on the effective date thereof, the Total BV Revolving
Extensions of Credit would exceed the Total BV Revolving Commitments. Any such
reduction shall be in an amount equal to E1,000,000, or a whole multiple
thereof, and shall reduce permanently the BV Revolving Commitments then in
effect.

            2.5   Optional Prepayments.

            The relevant Borrower may at any time and from time to time prepay
the Revolving Loans made to it, in whole or in part, without premium or penalty,
upon irrevocable notice delivered to the Administrative Agent no later than
11:00 A,M., London time, three Business Days prior thereto, which notice shall
specify the date and amount of prepayment; provided, that if a Revolving Loan is
prepaid on any day other than the last day of the Interest Period applicable
thereto, such Borrower shall also pay any amounts owing pursuant to Section
2.14. Upon receipt of any such notice the Administrative Agent shall promptly
notify each Lender thereof. If any such notice is given, the amount specified in
such notice shall be due and payable on the date specified therein, together
with accrued interest to such date on the amount prepaid. Partial prepayments of
Revolving Loans shall be in an aggregate principal amount of E500,000 or a whole
multiple thereof.

                                                                              14

            2.6   Continuation Options.

            Any Eurocurrency Loan may be continued as such upon the expiration
of the then current Interest Period with respect thereto by the relevant
Borrower giving irrevocable notice to the Administrative Agent, in accordance
with the applicable provisions of the term "Interest Period" set forth in
Section 1.1, of the length of the next Interest Period to be applicable to such
Revolving Loans, provided that if (a) any Event of Default has occurred and is
continuing and the Administrative Agent has or the Required Lenders have
determined in its or their sole discretion not to permit Eurocurrency Loans to
be continued as such for Interest Periods of more than one month or (b) the
relevant Borrower shall fail to give any required notice as described above in
this paragraph, such Revolving Loans shall be automatically continued as a
Eurocurrency Loan with an Interest Period of one month. Upon receipt of any such
notice the Administrative Agent shall promptly notify each Lender thereof.

            2.7   Limitations on Eurocurrency Tranches.

            Notwithstanding anything to the contrary in this Agreement, all
borrowings, conversions and continuations of Eurocurrency Loans and all
selections of Interest Periods shall be in such amounts and be made pursuant to
such elections so that, (a) after giving effect thereto, the aggregate principal
amount of the Eurocurrency Loans comprising each Eurocurrency Tranche shall be
equal to E500,000 or a whole multiple of E100,000 in excess thereof and (b) no
more than twenty Eurocurrency Tranches shall be outstanding at any one time.

            2.8   Interest Rates and Payment Dates.

            (a) Each Revolving Loan shall bear interest for each day during each
Interest Period with respect thereto at a rate per annum equal to the
Eurocurrency Rate determined for such day plus the Applicable Margin.

            (b) If (i) all or a portion of the principal amount of any Revolving
Loan shall not be paid when due (whether at the stated maturity, by acceleration
or otherwise) or (ii) if all or a portion of any interest payable on any
Revolving Loan or any commitment fee or other amount payable hereunder shall not
be paid when due (whether at the stated maturity, by acceleration or otherwise),
such overdue amount shall bear interest at a rate per annum equal to the rate
that would otherwise be applicable thereto pursuant to the foregoing provisions
of this Section plus 2%, in each case, with respect to clauses (i) and (ii)
above, from the date of such non-payment until such amount is paid in full (as
well after as before judgment).

            (c) Interest shall be payable in arrears on each Interest Payment
Date, provided that interest accruing pursuant to paragraph (c) of this Section
shall be payable from time to time on demand.

            2.9   Computation of Interest and Fees.

            (a) Interest and fees payable pursuant hereto shall be calculated on
the basis of a 360-day year for the actual days elapsed. The Administrative
Agent shall as soon as practicable notify the Borrowers and the Lenders of each
determination of a Eurocurrency Rate. Any change in the interest rate on a
Revolving Loan resulting from a change in the Eurocurrency Reserve Requirements
shall become effective as of the opening of business on the day on which such
change becomes effective. The Administrative Agent shall as soon as practicable
notify the Borrowers and the Lenders of the effective date and the amount of
each such change in interest rate.

<PAGE>

                                                                              15

            (b) Each determination of an interest rate by the Administrative
Agent pursuant to any provision of this Agreement shall be conclusive and
binding on the Borrowers and the Lenders in the absence of manifest error.

            2.10  Inability to Determine Interest Rate.

            If prior to the first day of any Interest Period:

            (a) the Administrative Agent shall have determined (which
      determination shall be conclusive and binding upon the Borrowers) that, by
      reason of circumstances affecting the relevant market, adequate and
      reasonable means do not exist for ascertaining the Eurocurrency Rate for
      such Interest Period, or

            (b) the Administrative Agent shall have received notice from the
      Required Lenders that the Eurocurrency Rate determined or to be determined
      for such Interest Period will not adequately and fairly reflect the cost
      to such Lenders (as conclusively certified by such Lenders) of making or
      maintaining their affected Revolving Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrowers and the Lenders as soon as practicable thereafter. If such notice is
given, any Revolving Loans comprising such Interest Period shall be maintained
at the rate reasonably determined by the Administrative Agent as the actual cost
of funding such Revolving Loans plus the Applicable Margin until such time as
such notice has been withdrawn by the Administrative Agent.

            2.11  Pro Rata Treatment and Payments.

            (a) Each borrowing by GMBH from the Lenders hereunder, each payment
by GMBH on account of any commitment fee and any reduction of the GMBH Revolving
Commitments of the Lenders shall be made pro rata according to the GMBH
Revolving Percentages of the relevant Lenders. Each borrowing by BV from the
Lenders hereunder, each payment by BV on account of any commitment fee and any
reduction of the BV Revolving Commitments of the Lenders shall be made pro rata
according to the BV Revolving Percentages of the relevant Lenders.

            (b) Each payment (including each prepayment) by GMBH on account of
principal of and interest on the GMBH Revolving Loans made to it shall be made
pro rata according to the respective outstanding principal amounts of the GMBH
Revolving Loans then held by the Lenders. Each payment (including each
prepayment) by BV on account of principal of and interest on the BV Revolving
Loans shall be made pro rata according to the respective outstanding principal
amounts of the BV Revolving Loans then held by the Lenders.

            (c) All payments (including prepayments) to be made by a Borrower
hereunder, whether on account of principal, interest, fees or otherwise, shall
be made without setoff or counterclaim and shall be made prior to 12:00 Noon,
London time, on the due date thereof to the Administrative Agent, for the
account of the Lenders, at the Funding Office, in Euros and in immediately
available funds. The Administrative Agent shall distribute such payments to the
Lenders promptly upon receipt in like funds as received. If any payment on a
Revolving Loan becomes due and payable on a day other than a Business Day, the
maturity thereof shall be extended to the next succeeding Business Day unless
the result of such extension would be to extend such payment into another
calendar month, in which event such payment shall be made on the immediately
preceding Business Day. In the case of any extension of any payment of principal
pursuant to the preceding two sentences, interest thereon shall be payable at
the then applicable rate during such extension.

                                                                              16

            (d) Unless the Administrative Agent shall have been notified in
writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its share of such borrowing available to the
Administrative Agent, the Administrative Agent may assume that such Lender is
making such amount available to the Administrative Agent, and the Administrative
Agent may, in reliance upon such assumption, make available to the relevant
Borrower a corresponding amount. If such amount is not made available to the
Administrative Agent by the required time on the Borrowing Date therefor, such
Lender shall pay to the Administrative Agent, on demand, such amount with
interest thereon, at a rate equal to a rate determined by the Administrative
Agent in accordance with banking industry rules on interbank compensation, for
the period until such Lender makes such amount immediately available to the
Administrative Agent. A certificate of the Administrative Agent submitted to any
Lender with respect to any amounts owing under this paragraph shall be
conclusive in the absence of manifest error. If such Lender's share of such
borrowing is not made available to the Administrative Agent by such Lender
within three Business Days after such Borrowing Date, the Administrative Agent
shall also be entitled to recover such amount with interest thereon at the rate
per annum applicable thereto, on demand, from the relevant Borrower.

            (e) Unless the Administrative Agent shall have been notified in
writing by the relevant Borrower prior to the date of any payment due to be made
by such Borrower hereunder that such Borrower will not make such payment to the
Administrative Agent, the Administrative Agent may assume that such Borrower is
making such payment, and the Administrative Agent may, but shall not be required
to, in reliance upon such assumption, make available to the Lenders their
respective pro rata shares of a corresponding amount. If such payment is not
made to the Administrative Agent by the relevant Borrower within three Business
Days after such due date, the Administrative Agent shall be entitled to recover,
on demand, from each Lender to which any amount which was made available
pursuant to the preceding sentence, such amount with interest thereon at the
rate per annum equal to the daily average rate of interest determined by the
Administrative Agent (which determination shall be conclusive absent manifest
error) to be the cost to it of obtaining funds for the relevant Interest Period.
Nothing herein shall be deemed to limit the rights of the Administrative Agent
or any Lender against the Borrowers.

            2.12  Requirements of Law.

            (a) If the adoption of or any change in any Requirement of Law or in
the interpretation or application thereof or compliance by any Lender with any
request or directive (whether or not having the force of law) from any central
bank or other Governmental Authority made subsequent to the date hereof:

            (i) shall subject any Lender to any tax of any kind whatsoever with
      respect to this Agreement or any Eurocurrency Loan made by it, or change
      the basis of taxation of payments to such Lender in respect thereof
      (except for Non-Excluded Taxes covered by Section 2.13 and changes in the
      rate of tax on the overall net income of such Lender);

            (ii) shall impose, modify or hold applicable any reserve, special
      deposit, compulsory loan or similar requirement against assets held by,
      deposits or other liabilities in or for the account of, advances, loans or
      other extensions of credit by, or any other acquisition of funds by, any
      office of such Lender that is not otherwise included in the determination
      of the Eurocurrency Rate; or

            (iii) shall impose on such Lender any other condition;

<PAGE>

                                                                              17

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount that such Lender deems to be material, of making, converting into,
continuing or maintaining Eurocurrency Loans, or to reduce any amount receivable
hereunder in respect thereof, then, in any such case, the relevant Borrower
shall promptly pay such Lender, upon its demand, any additional amounts
necessary to compensate such Lender for such increased cost or reduced amount
receivable. If any Lender becomes entitled to claim any additional amounts
pursuant to this paragraph, it shall promptly notify the relevant Borrower (with
a copy to the Administrative Agent) of the event by reason of which it has
become so entitled.

            (b) If any Lender shall have determined that the adoption of or any
change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder to a level below that which such Lender
or such corporation could have achieved but for such adoption, change or
compliance (taking into consideration such Lender's or such corporation's
policies with respect to capital adequacy) by an amount deemed by such Lender to
be material, then from time to time, after submission by such Lender to the
relevant Borrower (with a copy to the Administrative Agent) of a written request
therefor, the relevant Borrower shall pay to such Lender such additional amount
or amounts as will compensate such Lender or such corporation for such
reduction.

            (c) A certificate as to any additional amounts payable pursuant to
this Section submitted by any Lender to the relevant Borrower (with a copy to
the Administrative Agent) shall be conclusive in the absence of manifest error.
Notwithstanding anything to the contrary in this Section, no Borrower shall be
required to compensate a Lender pursuant to this Section for any amounts
incurred more than nine months prior to the date that such Lender notifies the
relevant Borrower of such Lender's intention to claim compensation therefor;
provided that, if the circumstances giving rise to such claim have a retroactive
effect, then such nine-month period shall be extended to include the period of
such retroactive effect. The obligations of the Borrowers pursuant to this
Section 2.12 shall survive until the date that is one year after the termination
of this Agreement and the payment of the Revolving Loans and all other amounts
payable hereunder.

            2.13  Taxes.

            (a) All payments made by the Borrowers under this Agreement shall be
made free and clear of, and without deduction or withholding for or on account
of, any present or future income, stamp or other taxes, levies, imposts, duties,
charges, fees, deductions or withholdings, now or hereafter imposed, levied,
collected, withheld or assessed by any Governmental Authority, excluding net
income taxes and franchise taxes (imposed in lieu of net income taxes) imposed
on the Administrative Agent or any Lender as a result of a present or former
connection between the Administrative Agent or such Lender and the jurisdiction
of the Governmental Authority imposing such tax or any political subdivision or
taxing authority thereof or therein (other than any such connection arising
solely from the Administrative Agent or such Lender having executed, delivered
or performed its obligations or received a payment under, or enforced, this
Agreement or any other Loan Document). If any such non-excluded taxes, levies,
imposts, duties, charges, fees, deductions or withholdings ("Non-Excluded
Taxes") or Other Taxes are required to be withheld from any amounts payable to
the Administrative Agent or any Lender hereunder, the amounts so payable to the
Administrative Agent or such Lender shall be increased to the extent necessary
to yield to the Administrative Agent or such Lender (after payment of all
Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable
hereunder at the rates or in the amounts specified in this Agreement, provided,
however, that the Borrowers shall not be required to

<PAGE>

                                                                              18

increase any such amounts payable to any Lender with respect to any Non-Excluded
Taxes (i) that are attributable to such Lender's failure to comply with the
requirements of paragraph (d) or (e) of this Section or (ii) that are United
States withholding taxes imposed on amounts payable to such Lender at the time
such Lender becomes a party to this Agreement, except to the extent that such
Lender's assignor (if any) was entitled, at the time of assignment, to receive
additional amounts from the relevant Borrower with respect to such Non-Excluded
Taxes pursuant to this paragraph.

            (b) In addition, the Borrowers shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

            (c) Whenever any Non-Excluded Taxes or Other Taxes are payable by a
Borrower, as promptly as possible thereafter such Borrower shall send to the
Administrative Agent for its own account or for the account of the relevant
Lender, as the case may be, a certified copy of an original official receipt
received by such Borrower showing payment thereof. If a Borrower fails to pay
any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing
authority or fails to remit to the Administrative Agent the required receipts or
other required documentary evidence, such Borrower shall indemnify the
Administrative Agent and the Lenders for any incremental taxes, interest or
penalties that may become payable by the Administrative Agent or any Lender as a
result of any such failure.

            (d) Each Lender (or Transferee) that is not a "U.S. Person" as
defined in Section 7701(a)(30) of the Code (a "Non-U.S. Lender") shall deliver
to the Borrowers and the Administrative Agent (or, in the case of a Participant,
to the Lender from which the related participation shall have been purchased)
two copies of either U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI,
or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal
withholding tax under Section 871(h) or 881(c) of the Code with respect to
payments of "portfolio interest", a statement substantially in the form of
Exhibit D and a Form W-8BEN, or any subsequent versions thereof or successors
thereto, properly completed and duly executed by such Non-U.S. Lender claiming
complete exemption from, or a reduced rate of, U.S. federal withholding tax on
all payments by the Borrowers under this Agreement and the other Loan Documents.
Such forms shall be delivered by each Non-U.S. Lender on or before the date it
becomes a party to this Agreement (or, in the case of any Participant, on or
before the date such Participant purchases the related participation). In
addition, each Non-U.S. Lender shall deliver such forms promptly upon the
obsolescence or invalidity of any form previously delivered by such Non-U.S.
Lender. Each Non-U.S. Lender shall promptly notify the Borrowers at any time it
determines that it is no longer in a position to provide any previously
delivered certificate to the Borrowers (or any other form of certification
adopted by the U.S. taxing authorities for such purpose). Notwithstanding any
other provision of this paragraph, a Non-U.S. Lender shall not be required to
deliver any form pursuant to this paragraph that such Non-U.S. Lender is not
legally able to deliver.

            (e) A Lender that is entitled to an exemption from or reduction of
non-U.S. withholding tax under the law of the jurisdiction in which the relevant
Borrower is located, or any treaty to which such jurisdiction is a party, with
respect to payments under this Agreement shall deliver to such Borrower (with a
copy to the Administrative Agent), at the time or times prescribed by applicable
law or reasonably requested by such Borrower, such properly completed and
executed documentation prescribed by applicable law as will permit such payments
to be made without withholding or at a reduced rate, provided that such Lender
is legally entitled to complete, execute and deliver such documentation and in
such Lender's judgment such completion, execution or submission would not
materially prejudice the legal position of such Lender.

            (f) If the Administrative Agent or any Lender determines, in its
sole discretion, that it has received a refund or credit of any Non-Excluded
Taxes or Other Taxes as to which it has been indemnified by the Borrowers or
with respect to which a Borrower has paid additional amounts pursuant

<PAGE>

                                                                              19

to this Section 2.13, it shall pay over such refund or credit to such Borrower
(but only to the extent of indemnity payments made, or additional amounts paid,
by such Borrower under this Section 2.13 with respect to the Non-Excluded Taxes
or Other Taxes giving rise to such refund or credit), net of all out-of-pocket
expenses of the Administrative Agent or such Lender and without interest (other
than any interest paid by the relevant Governmental Authority with respect to
such refund or credit); provided, that such Borrower, upon the request of the
Administrative Agent or such Lender, agrees to repay the amount paid over to
such Borrower (plus any penalties, interest or other charges imposed by the
relevant Governmental Authority) to the Administrative Agent or such Lender in
the event the Administrative Agent or such Lender is required to repay such
refund or credit to such Governmental Authority. This paragraph shall not be
construed to require the Administrative Agent or any Lender to make available
its tax returns (or any other information relating to its taxes which it deems
confidential) to a Borrower or any other Person.

            (g) The agreements in this Section 2.13 shall survive until the date
that is one year after the termination of this Agreement and the payment of the
Revolving Loans and all other amounts payable hereunder.

            2.14  Indemnity.

            Each Borrower agrees to indemnify each Lender for, and to hold each
Lender harmless from, any loss or expense that such Lender may sustain or incur
as a consequence of (a) default by such Borrower in making a borrowing of,
conversion into or continuation of Eurocurrency Loans after such Borrower has
given a notice requesting the same in accordance with the provisions of this
Agreement, (b) default by such Borrower in making any prepayment of or
conversion from Eurocurrency Loans after such Borrower has given a notice
thereof in accordance with the provisions of this Agreement or (c) the making of
a prepayment of Eurocurrency Loans on a day that is not the last day of an
Interest Period with respect thereto. Such indemnification may include an amount
equal to the excess, if any, of (i) the amount of interest that would have
accrued on the amount so prepaid, or not so borrowed, converted or continued,
for the period from the date of such prepayment or of such failure to borrow,
convert or continue to the last day of such Interest Period (or, in the case of
a failure to borrow, convert or continue, the Interest Period that would have
commenced on the date of such failure) in each case at the applicable rate of
interest for such Revolving Loans provided for herein (excluding, however, the
Applicable Margin included therein, if any) over (ii) the amount of interest (as
reasonably determined by such Lender after consultation with Novellus) that
would have accrued to such Lender on such amount by placing such amount on
deposit for a comparable period with leading banks in the interbank eurocurrency
market. A certificate as to any amounts payable pursuant to this Section
submitted to the relevant Borrower by any Lender shall be conclusive in the
absence of manifest error. This covenant shall survive the termination of this
Agreement and the payment of the Revolving Loans and all other amounts payable
hereunder until such time as any applicable statute of limitations has expired.

            2.15  Change of Lending Office.

            Each Lender agrees that, upon the occurrence of any event giving
rise to the operation of Section 2.12 or 2.13(a) with respect to such Lender, it
will, if requested by the relevant Borrower, use reasonable efforts (subject to
overall policy considerations of such Lender) to designate another lending
office for any Revolving Loans affected by such event with the object of
avoiding the consequences of such event; provided, that such designation is made
on terms that, in the sole judgment of such Lender, cause such Lender and its
lending office(s) to suffer no economic, legal or regulatory disadvantage, and
provided, further, that nothing in this Section shall affect or postpone any of
the obligations of any Borrower or the rights of any Lender pursuant to Section
2.12 or 2.13(a).

                                                                              20

            2.16  Replacement of Lenders.

            The relevant Borrower shall be permitted to replace any Lender that
(a) requests reimbursement for amounts owing pursuant to Section 2.12 or 2.13(a)
or (b) defaults in its obligation to make Revolving Loans hereunder, with a
replacement financial institution; provided that (i) such replacement does not
conflict with any Requirement of Law, (ii) no Event of Default shall have
occurred and be continuing at the time of such replacement, (iii) prior to any
such replacement, such Lender shall have taken no action under Section 2.15 so
as to eliminate the continued need for payment of amounts owing pursuant to
Section 2.12 or 2.13(a), (iv) the replacement financial institution shall
purchase, at par, all Revolving Loans and other amounts owing to such replaced
Lender on or prior to the date of replacement, (v) the relevant Borrowers shall
be liable to such replaced Lender under Section 2.14 if any Eurocurrency Loan
owing to such replaced Lender shall be purchased other than on the last day of
the Interest Period relating thereto, (vi) the replacement financial
institution, if not already a Lender, shall be reasonably satisfactory to the
Administrative Agent, (vii) the replaced Lender shall be obligated to make such
replacement in accordance with the provisions of Section 9.6 (provided that the
relevant Borrower shall be obligated to pay the registration and processing fee
referred to therein), (viii) until such time as such replacement shall be
consummated, the Borrowers shall pay all additional amounts (if any) required
pursuant to Section 2.12 or 2.13(a), as the case may be, and (ix) any such
replacement shall not be deemed to be a waiver of any rights that the Borrowers,
the Administrative Agent or any other Lender shall have against the replaced
Lender.

                    SECTION 3. REPRESENTATIONS AND WARRANTIES

            To induce the Administrative Agent and the Lenders to enter into
this Agreement and to make the Revolving Loans, Novellus and the Borrowers
hereby jointly and severally represent and warrant to the Administrative Agent
and each Lender that:

            3.1   Financial Condition.

            The audited consolidated balance sheets of Novellus and its
consolidated Subsidiaries as at December 31, 2001, December 31, 2002 and
December 31, 2003, and the related consolidated statements of income and of cash
flows for the fiscal years ended on such dates, reported on by and accompanied
by an unqualified report from Ernst & Young LLP, present fairly the consolidated
financial condition of Novellus and its consolidated Subsidiaries as at such
date, and the consolidated results of its operations and its consolidated cash
flows for the respective fiscal years then ended. The unaudited consolidated
balance sheet of Novellus and its consolidated Subsidiaries as at March 31,
2004, and the related unaudited consolidated statements of income and cash flows
for the three-month period ended on such date, present fairly the consolidated
financial condition of Novellus and its consolidated Subsidiaries as at such
date, and the consolidated results of its operations and its consolidated cash
flows for the three-month period then ended (subject to normal year-end audit
adjustments). All such financial statements, including the related schedules and
notes thereto, have been prepared in accordance with GAAP applied consistently
throughout the periods involved (except as approved by the aforementioned firm
of accountants and disclosed therein). No Group Member has any material
Guarantee Obligations, contingent liabilities and liabilities for taxes, or any
long-term leases or unusual forward or long-term commitments, including any
interest rate or foreign currency swap or exchange transaction or other
obligation in respect of derivatives, that are not reflected in the most recent
disclosure filings made by Novellus with the SEC. During the period from
December 31, 2003 to and including the date hereof there has been no Disposition
by any Group Member of any material part of its business or property for which
reasonable consideration has not been received.

            3.2   No Change.

                                                                              21

            Since December 31, 2003, there has been no development or event that
has had or could reasonably be expected to have a Material Adverse Effect.

            3.3   Existence; Compliance with Law.

            Each Group Member (a) is duly organized, validly existing and in
good standing under the laws of the jurisdiction of its organization, (b) has
the power and authority, and the legal right, to own and operate its property,
to lease the property it operates as lessee and to conduct the business in which
it is currently engaged, (c) is duly qualified as a foreign corporation or other
organization and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of property or the conduct of its business
requires such qualification except to the extent that the failure to so qualify
could not, in the aggregate, reasonably be expected to have a Material Adverse
Effect and (d) is in compliance with all Requirements of Law except to the
extent that the failure to comply therewith could not, in the aggregate,
reasonably be expected to have a Material Adverse Effect.

            3.4   Power; Authorization; Enforceable Obligations.

            Each Loan Party has the power and authority, and the legal right, to
make, deliver and perform the Loan Documents to which it is a party and, in the
case of each Borrower, to obtain extensions of credit hereunder. Each Loan Party
has taken all necessary organizational action to authorize the execution,
delivery and performance of the Loan Documents to which it is a party and, in
the case of each Borrower, to authorize the extensions of credit on the terms
and conditions of this Agreement. No consent or authorization of, filing with,
notice to or other act by or in respect of, any Governmental Authority or any
other Person is required in connection with the Acquisition and the extensions
of credit hereunder or with the execution, delivery, performance, validity or
enforceability of this Agreement or any of the Loan Documents, except consents,
authorizations, filings and notices which have been obtained or made and are in
full force and effect. Each Loan Document has been duly executed and delivered
on behalf of each Loan Party party thereto. This Agreement constitutes, and each
other Loan Document upon execution will constitute, a legal, valid and binding
obligation of each Loan Party party thereto, enforceable against each such Loan
Party in accordance with its terms, except as enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting the enforcement of creditors' rights generally and by general
equitable principles (whether enforcement is sought by proceedings in equity or
at law).

            3.5   No Legal Bar.

            The execution, delivery and performance of this Agreement and the
other Loan Documents, the borrowings hereunder and the use of the proceeds
thereof will not violate any Requirement of Law or any Contractual Obligation of
any Group Member and will not result in, or require, the creation or imposition
of any Lien on any of their respective properties or revenues pursuant to any
Requirement of Law or any such Contractual Obligation (other than the Liens
created by the Guarantee and Collateral Agreement). No Requirement of Law or
Contractual Obligation applicable to Novellus or any of its Subsidiaries could
reasonably be expected to have a Material Adverse Effect.

            3.6   Litigation.

            No litigation, investigation or proceeding of or before any
arbitrator or Governmental Authority is pending or, to the knowledge of Novellus
or either Borrower, threatened by or against any Group Member or against any of
their respective properties or revenues (a) with respect to any of the Loan
Documents or any of the transactions contemplated hereby or thereby, or (b) that
could reasonably be expected to have a Material Adverse Effect.

            3.7   No Default.

            No Group Member is in default under or with respect to any of its
Contractual Obligations in any respect that could reasonably be expected to have
a Material Adverse Effect. No Default or Event of Default has occurred and is
continuing.

            3.8   Ownership of Property.

            Each Group Member has title in fee simple to, or a valid leasehold
interest in, all its real property, and good title to, or a valid leasehold
interest in, all its other property.

            3.9   Intellectual Property.

            Except as disclosed from time to time in any filing made by Novellus
with the SEC, each Group Member owns, or is licensed to use, all Intellectual
Property necessary for the conduct of its business as currently conducted. No
material claim has been asserted and is pending by any Person challenging or
questioning the use of any Intellectual Property or the validity or
effectiveness of any Intellectual Property, nor does Novellus or either Borrower
know of any valid basis for any such claim.

            3.10  Taxes.

            Each Group Member has filed or caused to be filed all Federal, state
and other material tax returns that are required to be filed and has paid all
taxes shown to be due and payable on said returns or on any assessments made
against it or any of its property and all other taxes, fees or other charges
imposed on it or any of its property by any Governmental Authority (except to
the extent the amount or validity thereof is currently being contested in good
faith by appropriate proceedings and with respect to which reserves in
conformity with GAAP have been provided on the books of the relevant Group
Member); no tax Lien has been filed, and, to the knowledge of Novellus and each
Borrower, no claim is being asserted, with respect to any such tax, fee or other
charge.

            3.11  Federal Regulations.

            No part of the proceeds of any Revolving Loans, and no other
extensions of credit hereunder, will be used (a) for "buying" or "carrying" any
"margin stock" within the respective meanings of each of the quoted terms under
Regulation U as now and from time to time hereafter in effect for any purpose
that violates the provisions of the Regulations of the Board or (b) for any
purpose that violates the provisions of the Regulations of the Board. If
requested by any Lender or the Administrative Agent, the Borrowers will furnish
to the Administrative Agent and each Lender a statement to the foregoing effect
in conformity with the requirements of FR Form G-3 or FR Form U-1, as
applicable, referred to in Regulation U.

            3.12  ERISA.

            Neither a Reportable Event nor an "accumulated funding deficiency"
(within the meaning of Section 412 of the Code or Section 302 of ERISA) has
occurred during the five-year period prior to the date on which this
representation is made or deemed made with respect to any Plan, and each Plan
has complied in all material respects with the applicable provisions of ERISA
and the Code. No termination of a Single Employer Plan has occurred, and no Lien
in favor of the PBGC or a Plan has arisen, during such five-year period. The
present value of all accrued benefits under each Single Employer Plan (based on
those assumptions used to fund such Plans) did not, as of the last annual
valuation date prior to the date on which this representation is made or deemed
made, exceed the value of

<PAGE>

                                                                              23

the assets of such Plan allocable to such accrued benefits by a material amount.
Neither Novellus nor any Commonly Controlled Entity has had a complete or
partial withdrawal from any Multiemployer Plan that has resulted or could
reasonably be expected to result in a material liability under ERISA, and
neither Novellus nor any Commonly Controlled Entity would become subject to any
material liability under ERISA if Novellus or any such Commonly Controlled
Entity were to withdraw completely from all Multiemployer Plans as of the
valuation date most closely preceding the date on which this representation is
made or deemed made. No such Multiemployer Plan is in Reorganization or
Insolvent.

            3.13  Investment Company Act; Other Regulations.

            No Loan Party is an "investment company", or a company "controlled"
by an "investment company", within the meaning of the Investment Company Act of
1940, as amended. No Loan Party is subject to regulation under any Requirement
of Law (other than Regulation X of the Board) that limits its ability to incur
Indebtedness.

            3.14  Subsidiaries.

            As of the Closing Date, Schedule 3.14 sets forth the name and
jurisdiction of incorporation of each Subsidiary.

            3.15  Use of Proceeds.

            The proceeds of the Revolving Loans shall be used for general
corporate purposes, including to finance a portion of the Acquisition and to pay
related fees and expenses.

            3.16  Environmental Matters.

            Except as, in the aggregate, could not reasonably be expected to
have a Material Adverse Effect:

            (a) the facilities and properties owned, leased or operated by any
Group Member (the "Properties") do not contain, and have not previously
contained, any Materials of Environmental Concern in amounts or concentrations
or under circumstances that constitute or constituted a violation of, or could
give rise to liability under, any Environmental Law;

            (b) no Group Member has received or is aware of any notice of
violation, alleged violation, non-compliance, liability or potential liability
regarding environmental matters or compliance with Environmental Laws with
regard to any of the Properties or the business operated by any Group Member
(the "Business"), nor does Novellus or either Borrower have knowledge or reason
to believe that any such notice will be received or is being threatened;

            (c) Materials of Environmental Concern have not been transported or
disposed of from the Properties in violation of, or in a manner or to a location
that could give rise to liability under, any Environmental Law, nor have any
Materials of Environmental Concern been generated, treated, stored or disposed
of at, on or under any of the Properties in violation of, or in a manner that
could give rise to liability under, any applicable Environmental Law;

            (d) no judicial proceeding or governmental or administrative action
is pending or, to the knowledge of Novellus or either Borrower, threatened,
under any Environmental Law to which any Group Member is or will be named as a
party with respect to the Properties or the Business, nor are there any consent
decrees or other decrees, consent orders, administrative orders or other orders,
or other

                                                                              24

administrative or judicial requirements outstanding under any Environmental Law
with respect to the Properties or the Business;

            (e) there has been no release or threat of release of Materials of
Environmental Concern at or from the Properties, or arising from or related to
the operations of any Group Member in connection with the Properties or
otherwise in connection with the Business, in violation of or in amounts or in a
manner that could give rise to liability under Environmental Laws;

            (f) the Properties and all operations at the Properties are in
compliance, and have in the last five years been in compliance, with all
applicable Environmental Laws, and there is no contamination at, under or about
the Properties or violation of any Environmental Law with respect to the
Properties or the Business; and

            (g) no Group Member has assumed any liability of any other Person
under Environmental Laws.

            3.17  Accuracy of Information, etc.

            No statement or information contained in this Agreement, any other
Loan Document or any other document, certificate or statement furnished by or on
behalf of any Loan Party to the Administrative Agent or the Lenders, or any of
them, for use in connection with the transactions contemplated by this Agreement
or the other Loan Documents, contained as of the date such statement,
information, document or certificate was so furnished, any untrue statement of a
material fact or omitted to state a material fact necessary to make the
statements contained herein or therein not misleading. The projections and pro
forma financial information contained in the materials referenced above are
based upon good faith estimates and assumptions believed by management of
Novellus to be reasonable at the time made, it being recognized by the Lenders
that such financial information as it relates to future events is not to be
viewed as fact and that actual results during the period or periods covered by
such financial information may differ from the projected results set forth
therein by a material amount. There is no fact known to any Loan Party that
could reasonably be expected to have a Material Adverse Effect that has not been
expressly disclosed herein, in the other Loan Documents or in any other
documents, certificates and statements furnished to the Administrative Agent and
the Lenders for use in connection with the transactions contemplated hereby and
by the other Loan Documents.

            3.18  Guarantee and Collateral Agreement.

            The Guarantee and Collateral Agreement is effective to create in
favor of the Administrative Agent, for the benefit of the Lenders, a legal,
valid and enforceable security interest in the Collateral described therein and
proceeds thereof. When the Collateral is delivered to the Administrative Agent
and held by the Securities Intermediary in the Securities Account, the Guarantee
and Collateral Agreement and the Securities Account Control Agreement shall
constitute a fully perfected Lien on, and security interest in, all right, title
and interest of Novellus in such Collateral and the proceeds thereof, as
security for the Obligations (as defined in the Guarantee and Collateral
Agreement), in each case prior and superior in right to any other Person.

            3.19  Solvency.

            Each Loan Party is, and after giving effect to the Acquisition and
the incurrence of all Indebtedness and obligations being incurred in connection
herewith and therewith will be and will continue to be, Solvent.

            4.2   Conditions to Each Extension of Credit.

            The agreement of each Lender to make any Revolving Loan requested to

for avoidance of doubt, any continuation pursuant to Section 2.6) is subject to
the satisfaction of the following conditions precedent:

            (a) Representations and Warranties. Each of the representations and
      warranties made by any Loan Party in or pursuant to the Loan Documents
      shall be true and correct on and as of such date as if made on and as of
      such date, except to the extent any such representation and warranty
      specifically relates to any earlier date, in which case such
      representation and warranty shall have been true and correct on and as of
      such earlier date.

            (b) No Default. No Default or Event of Default shall have occurred

respects and shall be prepared in reasonable detail and in accordance with GAAP
applied (except as approved by such accountants or officer, as the case may be,
and disclosed in reasonable detail therein) consistently throughout the periods
reflected therein and with prior periods. For avoidance of doubt, the delivery

organizational existence and (ii) take all reasonable action to maintain all

same or a similar business, except to the extent Novellus or its Subsidiaries
maintains reasonable self-insurance with respect to such risks.

            5.6   Inspection of Property; Books and Records; Discussions.

of its books and records at any reasonable time and as often as may reasonably
be desired and to discuss the business, operations, properties and financial and
other condition of the Group Members with officers and employees of the Group

      Plan, (ii) any "accumulated funding deficiency" (as defined in Section 302
      of ERISA), whether or not waived, shall exist with respect to any Plan or

Lenders, the Administrative Agent may, or upon the request of the Required
Lenders, the Administrative Agent shall, by notice to the Borrowers declare the
Revolving Commitments to be terminated forthwith, whereupon the Revolving
Commitments shall immediately terminate; and (ii) with the consent of the
Required Lenders, the Administrative Agent may, or upon the request of the
Required Lenders, the Administrative Agent shall, by notice to the Borrowers,
declare the Revolving Loans (with accrued interest thereon) and all other
amounts owing under this Agreement and the other Loan Documents to be due and
payable forthwith, whereupon the same shall immediately become due and payable.
Except as expressly provided above in this Section, presentment, demand, protest
and all other notices of any kind are hereby expressly waived by Novellus and
the Borrowers.

                      SECTION 8. THE ADMINISTRATIVE AGENT

            8.1   Appointment.

            Each Lender hereby irrevocably designates and appoints the
Administrative Agent as the agent of such Lender under this Agreement and the
other Loan Documents, and each such Lender irrevocably authorizes the
Administrative Agent, in such capacity, to take such action on its behalf under
the provisions of this Agreement and the other Loan Documents and to exercise
such powers and perform such duties as are expressly delegated to the
Administrative Agent by the terms of this Agreement and the other Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement, the
Administrative Agent shall not have any duties or responsibilities, except those
expressly set forth herein, or any fiduciary relationship with any Lender, and
no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Administrative Agent.

            8.2   Delegation of Duties.

            The Administrative Agent may execute any of its duties under this
Agreement and the other Loan Documents by or through agents or attorneys-in-fact
and shall be entitled to advice of counsel concerning all matters pertaining to
such duties. The Administrative Agent shall not be responsible for the
negligence or misconduct of any agents or attorneys in-fact selected by it with
reasonable care.

            8.3   Exculpatory Provisions.

            Neither the Administrative Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any
action lawfully taken or omitted to be taken by it or such Person under or in
connection with this Agreement or any other Loan Document (except to the extent
that any of the foregoing resulted from its or such Person's own gross
negligence or willful

<PAGE>

                                                                              33

misconduct) or (ii) responsible in any manner to any of the Lenders for any
recitals, statements, representations or warranties made by any Loan Party or
any officer thereof contained in this Agreement or any other Loan Document or in
any certificate, report, statement or other document referred to or provided for
in, or received by the Administrative Agent under or in connection with, this
Agreement or any other Loan Document or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document or for any failure of any Loan Party a party thereto to perform its
obligations hereunder or thereunder. The Administrative Agent shall not be under
any obligation to any Lender to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this
Agreement or any other Loan Document, or to inspect the properties, books or
records of any Loan Party.

            8.4   Reliance by Administrative Agent.

            The Administrative Agent shall be entitled to rely, and shall be
fully protected in relying, upon any instrument, writing, resolution, notice,
consent, certificate, affidavit, letter, telecopy, telex or teletype message,
statement, order or other document or conversation believed by it to be genuine
and correct and to have been signed, sent or made by the proper Person or
Persons and upon advice and statements of legal counsel (including counsel to
Novellus or either Borrower), independent accountants and other experts selected
by the Administrative Agent. The Administrative Agent may deem and treat the
payee of any Note as the owner thereof for all purposes unless a written notice
of assignment, negotiation or transfer thereof shall have been filed with the
Administrative Agent. The Administrative Agent shall be fully justified in
failing or refusing to take any action under this Agreement or any other Loan
Document unless it shall first receive such advice or concurrence of the
Required Lenders (or, if so specified by this Agreement, all Lenders) as it
deems appropriate or it shall first be indemnified to its satisfaction by the
Lenders against any and all liability and expense that may be incurred by it by
reason of taking or continuing to take any such action. The Administrative Agent
shall in all cases be fully protected in acting, or in refraining from acting,
under this Agreement and the other Loan Documents in accordance with a request
of the Required Lenders (or, if so specified by this Agreement, all Lenders),
and such request and any action taken or failure to act pursuant thereto shall
be binding upon all the Lenders and all future holders of the Revolving Loans.

            8.5   Notice of Default.

            The Administrative Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default unless the
Administrative Agent has received notice from a Lender, Novellus or a Borrower
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default". In the event that the
Administrative Agent receives such a notice, the Administrative Agent shall give
notice thereof to the Lenders. The Administrative Agent shall take such action
with respect to such Default or Event of Default as shall be reasonably directed
by the Required Lenders (or, if so specified by this Agreement, all Lenders);
provided that unless and until the Administrative Agent shall have received such
directions, the Administrative Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem advisable in the best interests of the
Lenders.

            8.6   Non-Reliance on Administrative Agent and Other Lenders.

            Each Lender expressly acknowledges that neither the Administrative
Agent nor any of its officers, directors, employees, agents, attorneys-in-fact
or affiliates have made any representations or warranties to it and that no act
by the Administrative Agent hereafter taken, including any review of the affairs
of a Loan Party or any affiliate of a Loan Party, shall be deemed to constitute
any representation or warranty by the Administrative Agent to any Lender. Each
Lender represents to the Administrative

<PAGE>

                                                                              34

Agent that it has, independently and without reliance upon the Administrative
Agent or any other Lender, and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, operations, property, financial and other condition and
creditworthiness of the Loan Parties and their affiliates and made its own
decision to make its Revolving Loans hereunder and enter into this Agreement.
Each Lender also represents that it will, independently and without reliance
upon the Administrative Agent or any other Lender, and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit analysis, appraisals and decisions in taking or not taking action
under this Agreement and the other Loan Documents, and to make such
investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Loan Parties and their affiliates. Except for notices, reports and other
documents expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, the Administrative Agent shall not have any duty
or responsibility to provide any Lender with any credit or other information
concerning the business, operations, property, condition (financial or
otherwise), prospects or creditworthiness of any Loan Party or any affiliate of
a Loan Party that may come into the possession of the Administrative Agent or
any of its officers, directors, employees, agents, attorneys-in-fact or
affiliates.

            8.7   Indemnification.

            The Lenders agree to indemnify the Administrative Agent in its
capacity as such (to the extent not reimbursed by Novellus or a Borrower and
without limiting the obligation of Novellus or the Borrowers to do so), ratably
according to their respective Aggregate Exposure Percentages in effect on the
date on which indemnification is sought under this Section (or, if
indemnification is sought after the date upon which the Revolving Commitments
shall have terminated and the Revolving Loans shall have been paid in full,
ratably in accordance with such Aggregate Exposure Percentages immediately prior
to such date), from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind whatsoever that may at any time (whether before or after the payment
of the Revolving Loans) be imposed on, incurred by or asserted against the
Administrative Agent in any way relating to or arising out of, the Revolving
Commitments, this Agreement, any of the other Loan Documents or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by the
Administrative Agent under or in connection with any of the foregoing; provided
that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements that are found by a final and nonappealable
decision of a court of competent jurisdiction to have resulted from the
Administrative Agent's gross negligence or willful misconduct. The agreements in
this Section shall survive the payment of the Revolving Loans and all other
amounts payable hereunder.

            8.8   Administrative Agent in Its Individual Capacity.

            The Administrative Agent and its affiliates may make loans to,
accept deposits from and generally engage in any kind of business with any Loan
Party as though the Administrative Agent were not the Administrative Agent. With
respect to its Revolving Loans made or renewed by it, the Administrative Agent
shall have the same rights and powers under this Agreement and the other Loan
Documents as any Lender and may exercise the same as though it were not the
Administrative Agent, and the terms "Lender" and "Lenders" shall include the
Administrative Agent in its individual capacity.

            8.9   Successor Administrative Agent.

            The Administrative Agent may resign as Administrative Agent upon 10
days' notice to the Lenders and the Borrowers. If the Administrative Agent shall
resign as Administrative Agent under

<PAGE>

                                                                              35

this Agreement and the other Loan Documents, then the Required Lenders shall
appoint from among the Lenders a successor agent for the Lenders, which
successor agent shall (unless an Event of Default under Section 7(a) or Section
7(f) with respect to Novellus or a Borrower shall have occurred and be
continuing) be subject to approval by the Borrowers (which approval shall not be
unreasonably withheld or delayed), whereupon such successor agent shall succeed
to the rights, powers and duties of the Administrative Agent, and the term
"Administrative Agent" shall mean such successor agent effective upon such
appointment and approval, and the former Administrative Agent's rights, powers
and duties as Administrative Agent shall be terminated, without any other or
further act or deed on the part of such former Administrative Agent or any of
the parties to this Agreement or any holders of the Revolving Loans. If no
successor agent has accepted appointment as Administrative Agent by the date
that is 10 days following a retiring Administrative Agent's notice of
resignation, the retiring Administrative Agent's resignation shall nevertheless
thereupon become effective, and the Lenders shall assume and perform all of the
duties of the Administrative Agent hereunder until such time, if any, as the
Required Lenders appoint a successor agent as provided for above. After any
retiring Administrative Agent's resignation as Administrative Agent, the
provisions of this Section 8 shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Administrative Agent under this
Agreement and the other Loan Documents.

                            SECTION 9. MISCELLANEOUS

            9.1   Amendments and Waivers.

            Neither this Agreement, any other Loan Document, nor any terms
hereof or thereof may be amended, supplemented or modified except in accordance
with the provisions of this Section 9.1. The Required Lenders and each Loan
Party party to the relevant Loan Document may, or, with the written consent of
the Required Lenders, the Administrative Agent and each Loan Party party to the
relevant Loan Document may, from time to time, (a) enter into written
amendments, supplements or modifications hereto and to the other Loan Documents
for the purpose of adding any provisions to this Agreement or the other Loan
Documents or changing in any manner the rights of the Lenders or of the Loan
Parties hereunder or thereunder or (b) waive, on such terms and conditions as
the Required Lenders or the Administrative Agent, as the case may be, may
specify in such instrument, any of the requirements of this Agreement or the
other Loan Documents or any Default or Event of Default and its consequences;
provided, however, that no such waiver and no such amendment, supplement or
modification shall (i) forgive the principal amount or extend the final
scheduled date of maturity of any Revolving Loan, reduce the stated rate of any
interest or fee payable hereunder (except in connection with the waiver of
applicability of any post-default increase in interest rates (which waiver shall

voting rights of any Lender under this Section 9.1 without the written consent
of such Lender; (iii) reduce any percentage specified in the definition of

Administrative Agent. Any such waiver and any such amendment, supplement or
modification shall apply equally to each of the Lenders and shall be binding
upon the Loan Parties, the Lenders, the Administrative Agent and all future
holders of the Revolving Loans. In the case of any waiver, the Loan Parties, the
Lenders and the Administrative Agent shall be restored to their former position
and rights hereunder and under the other Loan Documents, and any Default or
Event of Default waived shall be deemed to be cured and not continuing; but no
such

            No failure to exercise and no delay in exercising, on the part of
the Administrative Agent or any Lender, any right, remedy, power or privilege
hereunder or under the other Loan Documents shall operate as a waiver thereof;

privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, remedy, power or privilege. The rights, remedies,
powers and privileges herein provided are cumulative and not exclusive of any
rights, remedies, powers and privileges provided by law.

            9.4   Survival of Representations and Warranties.

            All representations and warranties made hereunder, in the other Loan

credit hereunder.

            9.5   Payment of Expenses and Taxes.

            Novellus agrees (a) to pay or reimburse the Administrative Agent for
all its out-of-pocket costs and expenses incurred in connection with the
development, preparation and execution of, and any amendment, supplement or
modification to, this Agreement and the other Loan Documents and any other
documents prepared in connection herewith or therewith, and the consummation and
administration of the transactions contemplated hereby and thereby, including
the reasonable fees and disbursements of counsel to the Administrative Agent
(which fees and disbursements of counsel shall be limited to $85,000 with
respect to the development, preparation and execution of this Agreement and the
other Loan Documents and any other documents prepared in connection herewith or
therewith) and filing and recording fees and expenses, with statements with
respect to the foregoing to be submitted to Novellus prior to the Closing Date
(in the case of amounts to be paid on the Closing Date) and from time to time
thereafter on a quarterly basis or such other periodic basis as the
Administrative Agent shall deem appropriate, (b) to pay or reimburse each Lender
and the Administrative Agent for all its costs and expenses incurred in
connection with the enforcement or preservation of any rights under this
Agreement, the other Loan Documents and any such other documents, including the
fees and disbursements of counsel (including the allocated fees and expenses of
in-house counsel) to each Lender and of counsel to the Administrative Agent, (c)
to pay, indemnify, and hold each Lender and the Administrative Agent harmless
from, any and all recording and filing fees and any and all liabilities with
respect to, or resulting from any delay in paying, stamp, excise and other
taxes, if any, that may be payable or determined to be payable in connection
with the execution and delivery of, or consummation or administration of any of
the transactions contemplated by, or any amendment, supplement or modification
of, or any waiver or consent under or in respect of, this Agreement, the other

                                                                              38

and (d) to pay, indemnify, and hold each Lender and the Administrative Agent and
their respective officers, directors, employees, affiliates, agents and
controlling persons (each, an "Indemnitee") harmless from and against any and
all other liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever with respect to the execution, delivery, enforcement, performance and
administration of this Agreement, the other Loan Documents and any such other
documents, including any of the foregoing relating to the use of proceeds of the
Revolving Loans or the violation of, noncompliance with or liability under, any
Environmental Law applicable to the operations of any Group Member or any of the
Properties and the reasonable fees and expenses of legal counsel in connection
with claims, actions or proceedings by any Indemnitee against any Loan Party
under any Loan Document (all the foregoing in this clause (d), collectively, the
"Indemnified Liabilities"), provided, that Novellus shall have no obligation
hereunder to any Indemnitee with respect to Indemnified Liabilities to the
extent such Indemnified Liabilities resulted from the gross negligence or
willful misconduct of such Indemnitee. Without limiting the foregoing, and to
the extent permitted by applicable law, Novellus agrees not to assert and to
cause its Subsidiaries not to assert, and hereby waives and agrees to cause its
Subsidiaries to waive, all rights for contribution or any other rights of
recovery with respect to all claims, demands, penalties, fines, liabilities,
settlements, damages, costs and expenses of whatever kind or nature, under or
related to Environmental Laws, that any of them might have by statute or
otherwise against any Indemnitee. All amounts due under this Section 9.5 shall
be payable not later than 10 days after written demand therefor. Statements
payable by Novellus pursuant to this Section 9.5 shall be submitted to Novellus
at the address, telecopy number and telephone number of Novellus set forth in
Section 9.2, or to such other Person or address as may be hereafter designated
by Novellus in a written notice to the Administrative Agent. The agreements in
this Section 9.5 shall survive repayment of the Revolving Loans and all other
amounts payable hereunder.

            9.6   Successors and Assigns; Participations and Assignments.

            (a) The provisions of this Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that (i) each of Novellus and each Borrower may not
assign or otherwise transfer any of its rights or obligations hereunder without
the prior written consent of each Lender (and any attempted assignment or
transfer by Novellus or a Borrower without such consent shall be null and void)
and (ii) no Lender may assign or otherwise transfer its rights or obligations
hereunder except in accordance with this Section.

            (b) (i) Subject to the conditions set forth in paragraph (b)(ii)
below, any Lender may assign to one or more assignees (each, an "Assignee") all
or a portion of its rights and obligations under this Agreement (including all
or a portion of its Revolving Commitments and the Revolving Loans at the time
owing to it) with the prior written consent of:

            (A) the Loan Parties (such consent not to be unreasonably withheld),
      provided that no consent of the Loan Parties shall be required for an
      assignment to a Lender, an affiliate of a Lender, an Approved Fund (as
      defined below) or, if an Event of Default has occurred and is continuing,
      any other Person; and

            (B) the Administrative Agent (such consent not to be unreasonably
      withheld).

            (ii) Assignments shall be subject to the following additional
      conditions:

            (A) except in the case of an assignment to a Lender, an affiliate of
      a Lender or an Approved Fund or an assignment of the entire remaining
      amount of the assigning Lender's Revolving Commitments or Revolving Loans,
      the amount of the Revolving Commitments or Revolving Loans of the
      assigning Lender subject to each such assignment (determined as of the

<PAGE>

                                                                              39

      date the Assignment and Assumption with respect to such assignment is
      delivered to the Administrative Agent) shall not be less than E15,000,000
      unless each of the Loan Parties and the Administrative Agent otherwise
      consent, provided that (1) no such consent of the Loan Parties shall be
      required if an Event of Default has occurred and is continuing and (2)
      such amounts shall be aggregated in respect of each Lender and its
      affiliates or Approved Funds, if any;

            (B) the parties to each assignment shall execute and deliver to the
      Administrative Agent an Assignment and Assumption, together with a
      processing and recordation fee of $3,500 (payable by the assigning Lender
      or the Assignee); and

            (C) the Assignee, if it shall not be a Lender, shall deliver to the
      Administrative Agent an administrative questionnaire.

            For the purposes of this Section 9.6, "Approved Fund" means any
Person (other than a natural person) that is engaged in making, purchasing,
holding or investing in bank loans and similar extensions of credit in the
ordinary course of its business and that is administered or managed by (a) a
Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an
entity that administers or manages a Lender.

            (iii) Subject to acceptance and recording thereof pursuant to
paragraph (b)(iv) below, from and after the effective date specified in each
Assignment and Assumption the Assignee thereunder shall be a party hereto and,
to the extent of the interest assigned by such Assignment and Assumption, have
the rights and obligations of a Lender under this Agreement, and the assigning
Lender thereunder shall, to the extent of the interest assigned by such
Assignment and Assumption, be released from its obligations under this Agreement
(and, in the case of an Assignment and Assumption covering all of the assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto but shall continue to be entitled to the benefits of Sections
2.12, 2.13, 2.14 and 9.5). Any assignment or transfer by a Lender of rights or
obligations under this Agreement that does not comply with this Section 9.6
shall be treated for purposes of this Agreement as a sale by such Lender of a
participation in such rights and obligations in accordance with paragraph (c) of
this Section.

            (iv) The Administrative Agent, acting for this purpose as an agent
of the Borrowers, shall maintain at one of its offices a copy of each Assignment
and Assumption delivered to it and a register for the recordation of the names
and addresses of the Lenders, and the Revolving Commitments of, and principal
amount of the Revolving Loans owing to, each Lender pursuant to the terms hereof
from time to time (the "Register"). The entries in the Register shall be
conclusive, and the Loan Parties, the Administrative Agent and the Lenders may
treat each Person whose name is recorded in the Register pursuant to the terms
hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding
notice to the contrary.

            (v) Upon its receipt of a duly completed Assignment and Assumption
executed by an assigning Lender and an Assignee, the Assignee's completed
administrative questionnaire (unless the Assignee shall already be a Lender
hereunder), the processing and recordation fee referred to in paragraph (b) of
this Section and any written consent to such assignment required by paragraph
(b) of this Section, the Administrative Agent shall accept such Assignment and
Assumption and record the information contained therein in the Register. No
assignment shall be effective for purposes of this Agreement unless it has been
recorded in the Register as provided in this paragraph.

            (c) (i) Any Lender may, without the consent of the Loan Parties or
the Administrative Agent, sell participations to one or more banks or other
entities (a "Participant") in all or a portion of such Lender's rights and
obligations under this Agreement (including all or a portion of its Revolving

<PAGE>

                                                                              40

Commitments and the Revolving Loans owing to it); provided that (A) such
Lender's obligations under this Agreement shall remain unchanged, (B) such
Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations and (C) the Loan Parties, the Administrative
Agent and the other Lenders shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement. Any agreement pursuant to which a Lender sells such a participation
shall provide that such Lender shall retain the sole right to enforce this
Agreement and to approve any amendment, modification or waiver of any provision
of this Agreement; provided that such agreement may provide that such Lender
will not, without the consent of the Participant, agree to any amendment,
modification or waiver that (1) requires the consent of each Lender directly
affected thereby pursuant to the proviso to the second sentence of Section 9.1
and (2) directly affects such Participant. Subject to paragraph (c)(ii) of this
Section, the Loan Parties agree that each Participant shall be entitled to the
benefits of Sections 2.12, 2.13 and 2.14 to the same extent as if it were a
Lender and had acquired its interest by assignment pursuant to paragraph (b) of
this Section. To the extent permitted by law, each Participant also shall be
entitled to the benefits of Section 9.7(b) as though it were a Lender, provided
such Participant shall be subject to Section 9.7(a) as though it were a Lender.

            (ii) A Participant shall not be entitled to receive any greater
payment under Section 2.12 or 2.13 than the applicable Lender would have been
entitled to receive with respect to the participation sold to such Participant,
unless the sale of the participation to such Participant is made with the Loan
Parties' prior written consent. Any Participant that is a Non-U.S. Lender shall
not be entitled to the benefits of Section 2.13 unless such Participant complies
with Section 2.13(d).

            (d) Any Lender may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement to secure obligations
of such Lender, including any pledge or assignment to secure obligations to a
Federal Reserve Bank, and this Section shall not apply to any such pledge or
assignment of a security interest; provided that no such pledge or assignment of
a security interest shall release a Lender from any of its obligations hereunder
or substitute any such pledgee or Assignee for such Lender as a party hereto.

            (e) The relevant Borrower, upon receipt of written notice from the
relevant Lender, agrees to issue Notes to any Lender requiring Notes to
facilitate transactions of the type described in paragraph (d) above.

            (f) Notwithstanding the foregoing, any Conduit Lender may assign any
or all of the Revolving Loans it may have funded hereunder to its designating
Lender without the consent of the Loan Parties or the Administrative Agent and
without regard to the limitations set forth in Section 9.6(b). Each Loan Party,
each Lender and the Administrative Agent hereby confirms that it will not
institute against a Conduit Lender or join any other Person in instituting
against a Conduit Lender any bankruptcy, reorganization, arrangement, insolvency
or liquidation proceeding under any state bankruptcy or similar law, for one
year and one day after the payment in full of the latest maturing commercial
paper note issued by such Conduit Lender; provided, however, that each Lender
designating any Conduit Lender hereby agrees to indemnify, save and hold
harmless each other party hereto for any loss, cost, damage or expense arising
out of its inability to institute such a proceeding against such Conduit Lender
during such period of forbearance.

            9.7   Adjustments; Set-off.

            (a) Except to the extent that this Agreement expressly provides for
payments to be allocated to a particular Lender, if any Lender (a "Benefitted
Lender") shall, at any time after the Revolving Loans and other amounts payable
hereunder shall immediately become due and payable pursuant to Section 7,
receive any payment of all or part of the Obligations owing to it, or receive
any

<PAGE>

                                                                              41

collateral in respect thereof (whether voluntarily or involuntarily, by set-off,
pursuant to events or proceedings of the nature referred to in Section 7(f), or
otherwise), in a greater proportion than any such payment to or collateral
received by any other Lender, if any, in respect of the Obligations owing to
such other Lender, such Benefitted Lender shall purchase for cash from the other
Lenders a participating interest in such portion of the Obligations owing to
each such other Lender, or shall provide such other Lenders with the benefits of
any such collateral, as shall be necessary to cause such Benefitted Lender to
share the excess payment or benefits of such collateral ratably with each of the
Lenders; provided, however, that if all or any portion of such excess payment or
benefits is thereafter recovered from such Benefitted Lender, such purchase
shall be rescinded, and the purchase price and benefits returned, to the extent
of such recovery, but without interest.

            (b) In addition to any rights and remedies of the Lenders provided
by law, each Lender shall have the right, without prior notice to Novellus or
either Borrower, any such notice being expressly waived by Novellus and each
Borrower to the extent permitted by applicable law, upon any amount becoming due
and payable by Novellus or a Borrower hereunder (whether at the stated maturity,
by acceleration or otherwise), to set off and appropriate and apply against such
amount any and all deposits (general or special, time or demand, provisional or
final), in any currency, and any other credits, indebtedness or claims, in any
currency, in each case whether direct or indirect, absolute or contingent,
matured or unmatured, at any time held or owing by such Lender or any branch or
agency thereof to or for the credit or the account of Novellus or a Borrower, as
the case may be; provided that to the extent any Lender exercises any such right
against Novellus, such Lender shall be limited to setting off and appropriating
and applying against such amount any and all deposits (general or special, time
or demand, provisional or final) in the Securities Account, in any currency, and
any other credits, indebtedness or claims with respect to the Securities
Account, in any currency, in each case whether direct or indirect, absolute or
contingent, matured or unmatured. Each Lender agrees promptly to notify the
Borrowers and the Administrative Agent after any such setoff and application
made by such Lender, provided that the failure to give such notice shall not
affect the validity of such setoff and application.

            9.8   Counterparts.

            This Agreement may be executed by one or more of the parties to this
Agreement on any number of separate counterparts, and all of said counterparts
taken together shall be deemed to constitute one and the same instrument.
Delivery of an executed signature page of this Agreement by facsimile
transmission shall be effective as delivery of a manually executed counterpart
hereof. A set of the copies of this Agreement signed by all the parties shall be
lodged with Novellus and the Administrative Agent.

            9.9   Severability.

            Any provision of this Agreement that is prohibited or unenforceable
in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent
of such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

            9.10  Integration.

            This Agreement and the other Loan Documents represent the entire
agreement of Novellus, the Borrowers, the Administrative Agent and the Lenders
with respect to the subject matter hereof and thereof, and there are no
promises, undertakings, representations or warranties by the Administrative
Agent or any Lender relative to the subject matter hereof not expressly set
forth or referred to herein or in the other Loan Documents.

            9.12  Submission To Jurisdiction; Waivers.

            Each of Novellus and each Borrower hereby irrevocably and
unconditionally:

            (a) submits for itself and its property in any legal action or
      proceeding relating to this Agreement and the other Loan Documents to
      which it is a party, or for recognition and enforcement of any judgment in
      respect thereof, to the non-exclusive general jurisdiction of the courts

            9.18  Judgment Currency.

            (a) If for the purpose of obtaining judgment in any court it is
necessary to convert a sum due hereunder in one currency into another currency,
the parties hereto agree, to the fullest extent that they may effectively do so,
that the rate of exchange used shall be that at which in accordance with normal
banking procedures the Administrative Agent could purchase the first currency
with such other currency in the city in which it normally conducts its foreign
exchange operation for the first currency on the Business Day preceding the day
on which final judgment is given.

            (b) The obligation of each Borrower in respect of any sum due from
it to any Lender hereunder shall, notwithstanding any judgment in a currency
(the "Judgment Currency") other than that in which such sum is denominated in
accordance with the applicable provisions of this Agreement (the "Agreement
Currency"), be discharged only to the extent that on the Business Day following
receipt by such Lender of any sum adjudged to be so due in the Judgment Currency
such Lender may in accordance with normal banking procedures purchase the
Agreement Currency with the Judgment Currency; if the amount of Agreement
Currency so purchased is less than the sum originally due to such Lender in the
Agreement Currency, such Borrower agrees notwithstanding any such judgment to
indemnify such Lender against such loss, and if the amount of the Agreement
Currency so purchased exceeds the sum originally due to any Lender, such Lender
agrees to remit to such Borrower such excess.

      (c)   Novellus agrees that the Borrower Obligations may at any time and
from time to time exceed the amount of the liability of Novellus hereunder
without impairing the guarantee contained in this Section 2 or affecting the
rights and remedies of the Administrative Agent or any Lender hereunder.

      (d)   The guarantee contained in this Section 2 shall remain in full force
and effect until all the Borrower Obligations and the obligations of Novellus
under the guarantee contained in this Section 2 shall have been satisfied by
payment in full and the Revolving Commitments shall be terminated,
notwithstanding that from time to time during the term of the Credit Agreement
the Borrowers may be free from any Borrower Obligations.

      (e)   No payment made by the Borrowers, any other guarantor or any other
Person or received or collected by the Administrative Agent or any Lender from
the Borrowers, any other guarantor or any other Person by virtue of any action
or proceeding or any set-off or appropriation or application at any time or from
time to time in reduction of or in payment of the Borrower Obligations shall be
deemed to modify, reduce, release or otherwise affect the liability of Novellus
hereunder which shall, notwithstanding any such payment (other than any payment
made by Novellus in respect of the Borrower Obligations or any payment received
or collected from Novellus in respect of the Borrower Obligations), remain
liable for the Borrower Obligations up to the maximum liability of Novellus
hereunder until the Borrower Obligations are paid in full and the Revolving
Commitments are terminated.

      2.2   No Subrogation.

            Notwithstanding any payment made by Novellus hereunder or any
set-off or application of funds of Novellus by the Administrative Agent or any
Lender, Novellus shall not be entitled to be subrogated to any of the rights of
the Administrative Agent or any Lender against the Borrowers or any collateral
security or guarantee or right of offset held by the Administrative Agent or any
Lender for the payment of the Borrower Obligations, nor shall Novellus seek or
be entitled to seek any contribution or reimbursement from the Borrowers in
respect of payments made by Novellus hereunder, until all amounts owing to the
Administrative Agent and the Lenders by the Borrowers on account of the Borrower
Obligations are paid in full and the Revolving Commitments are terminated. If
any amount shall be paid to Novellus on account of such subrogation rights at
any time when all of the Borrower Obligations shall

                                                                               4

not have been paid in full, such amount shall be held by Novellus in trust for
the Administrative Agent and the Lenders, segregated from other funds of
Novellus, and shall, forthwith upon receipt by Novellus, be turned over to the
Administrative Agent in the exact form received by Novellus (duly indorsed by
Novellus to the Administrative Agent, if required), to be applied against the
Borrower Obligations, whether matured or unmatured, in such order as the
Administrative Agent may determine.

      2.3   Amendments, etc. with respect to the Borrower Obligations.

            Novellus shall remain obligated hereunder notwithstanding that,
without any reservation of rights against Novellus and without notice to or
further assent by Novellus, any demand for payment of any of the Borrower
Obligations made by the Administrative Agent or any Lender may be rescinded by
the Administrative Agent or such Lender and any of the Borrower Obligations
continued, and the Borrower Obligations, or the liability of any other Person
upon or for any part thereof, or any collateral security or guarantee therefor
or right of offset with respect thereto, may, from time to time, in whole or in
part, be renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered or released by the Administrative Agent or any Lender, and the
Credit Agreement and the other Loan Documents and any other documents executed
and delivered in connection therewith may be amended, modified, supplemented or
terminated, in whole or in part, as the Administrative Agent (or the Required
Lenders or all Lenders, as the case may be) may deem advisable from time to
time, and any collateral security, guarantee or right of offset at any time held
by the Administrative Agent or any Lender for the payment of the Borrower
Obligations may be sold, exchanged, waived, surrendered or released. Neither the
Administrative Agent nor any Lender shall have any obligation to protect,
secure, perfect or insure any Lien at any time held by it as security for the
Borrower Obligations or for the guarantee contained in this Section 2 or any
property subject thereto.

      2.4   Guarantee Absolute and Unconditional.

            Novellus waives any and all notice of the creation, renewal,
extension or accrual of any of the Borrower Obligations and notice of or proof
of reliance by the Administrative Agent or any Lender upon the guarantee
contained in this Section 2 or acceptance of the guarantee contained in this
Section 2; the Borrower Obligations, and any of them, shall conclusively be
deemed to have been created, contracted or incurred, or renewed, extended,
amended or waived, in reliance upon the guarantee contained in this Section 2;
and all dealings between the Borrowers and Novellus, on the one hand, and the
Administrative Agent and the Lenders, on the other hand, likewise shall be
conclusively presumed to have been had or consummated in reliance upon the
guarantee contained in this Section 2. Novellus waives diligence, presentment,
protest, demand for payment and notice of default or nonpayment to or upon the
Borrowers with respect to the Borrower Obligations. Novellus understands and
agrees that the guarantee contained in this Section 2 shall be construed as a
continuing, absolute and unconditional guarantee of payment without regard to
(a) the validity or enforceability of the Credit Agreement or any other Loan
Document, any of the Borrower Obligations or any other collateral security
therefor or guarantee or right of offset with respect thereto at any time or
from time to time held by the Administrative Agent or any Lender, (b) any
defense, set-off or counterclaim (other than a defense of payment or
performance) which may at any time be available to or be asserted by any
Borrower or any other Person against the Administrative Agent or any Lender, or
(c) any other circumstance whatsoever (with or without notice to or knowledge of
the Borrowers or Novellus) which constitutes, or might be construed to
constitute, an equitable or legal discharge of the Borrowers for the Borrower
Obligations, or of Novellus under the guarantee contained in this Section 2, in
bankruptcy or in any other instance. When making any demand hereunder or
otherwise pursuing its rights and remedies hereunder against Novellus, the
Administrative Agent or any Lender may, but shall be under no obligation to,
make a similar demand on or otherwise pursue such rights and remedies as it may
have against the Borrowers or any other Person or against any collateral
security or guarantee for the Borrower Obligations or any right of offset with
respect thereto, and any failure by the

<PAGE>

                                                                               5

Administrative Agent or any Lender to make any such demand, to pursue such other
rights or remedies or to collect any payments from the Borrowers or any other
Person or to realize upon any such collateral security or guarantee or to
exercise any such right of offset, or any release of the Borrowers or any other
Person or any such collateral security, guarantee or right of offset, shall not
relieve Novellus of any obligation or liability hereunder, and shall not impair
or affect the rights and remedies, whether express, implied or available as a
matter of law, of the Administrative Agent or any Lender against Novellus. For
the purposes hereof "demand" shall include the commencement and continuance of
any legal proceedings.

      2.5   Reinstatement.

            The guarantee contained in this Section 2 shall continue to be
effective, or be reinstated, as the case may be, if at any time payment, or any
part thereof, of any of the Borrower Obligations is rescinded or must otherwise
be restored or returned by the Administrative Agent or any Lender upon the
insolvency, bankruptcy, dissolution, liquidation or reorganization of any
Borrower or Novellus, or upon or as a result of the appointment of a receiver,
intervenor or conservator of, or trustee or similar officer for, any Borrower or
Novellus or any substantial part of its property, or otherwise, all as though
such payments had not been made.

      2.6   Payments.

            Novellus hereby guarantees that payments hereunder will be paid to
the Administrative Agent without set-off or counterclaim in Dollars at the
Funding Office.

                  SECTION 3. COLLATERAL AND SECURITIES ACCOUNT

      3.1   Grant of Security Interest.

            Novellus hereby assigns and transfers to the Administrative Agent,
and hereby grants to the Administrative Agent, for the ratable benefit of the
Lenders, a security interest in and to, all of Novellus' right, title and
interest in and to the Collateral, as collateral security for the prompt and
complete payment and performance when due (whether at the stated maturity, by
acceleration or otherwise) of Novellus' Obligations.

      3.2   Maintenance of Securities Account.

            Pursuant to the Securities Account Control Agreement, the Securities
Account shall be maintained until Novellus' Obligations have been paid and
performed in full.

      3.3   Withdrawals from Securities Account.

            (a) If on any Measurement Date, the Collateral Ratio is greater than
1.00 to 1.00, by giving a Securities Transfer Notice within five Business Days
of such Measurement Date to the Securities Intermediary pursuant to the terms of
the Securities Account Control Agreement, Novellus may cause the transfer to it
of Marketable Securities from the Securities Account in an amount such that if
such Marketable Securities had not been on deposit in the Securities Account on
such Measurement Date, the Collateral Ratio would have been 1:00 to 1.00;
provided that Novellus may not cause such a transfer of Marketable Securities
unless such withdrawal would be of $1,000,000 or more of Marketable Securities.
Novellus shall not give a Securities Transfer Notice to the Securities
Intermediary except in compliance with the preceding sentence. Within one
Business Day of the Administrative Agent's receipt of a Securities Transfer
Notice presented to it by Novellus in compliance with the preceding sentence,
the

<PAGE>

                                                                               6

Administrative Agent shall execute and deliver to the Securities Intermediary
such Securities Transfer Notice.

      (b) Novellus shall not trade, withdraw, transfer, redeem or otherwise
cause the release of Marketable Securities from the Securities Account unless,
after giving pro forma effect to such trade, withdrawal, transfer, redemption or
release, the Collateral Ratio shall not be less than 1.00 to 1.00.

      3.4   Deposits to Securities Account.

            If on any Measurement Date, the Collateral Ratio is less than 1.00
to 1.00, Novellus shall, within five Business Days of such Measurement Date,
cause Marketable Securities to be deposited in the Securities Account such that
if such Marketable Securities had been on deposit in the Securities Account on
such Measurement Date, the Collateral Ratio on such Measurement Note would have
been at least 1.00 to 1.00.

                   SECTION 4. REPRESENTATIONS AND WARRANTIES

            To induce the Administrative Agent and the Lenders to enter into the
Credit Agreement and to induce the Lenders to make their respective extensions
of credit to the Borrowers thereunder, Novellus hereby represents and warrants
to the Administrative Agent and each Lender that:

      4.1   Title; No Other Liens.

            Except for the security interest granted to the Administrative Agent
for the ratable benefit of the Lenders pursuant to this Agreement, Novellus owns
each item of the Collateral free and clear of any and all Liens or claims of
others. No financing statement or other public notice with respect to all or any
part of the Collateral is on file or of record in any public office, except such
as have been filed in favor of the Administrative Agent, for the ratable benefit
of the Lenders, pursuant to this Agreement.

      4.2   Perfected First Priority Liens.

            The security interests granted pursuant to this Agreement (a)
constitute valid perfected security interests in all of the Collateral in favor
of the Administrative Agent, for the ratable benefit of the Lenders, as
collateral security for Novellus' Obligations, enforceable in accordance with
the terms hereof against all creditors of Novellus and any Persons purporting to
purchase any Collateral from Novellus and (b) are prior to all other Liens on
the Collateral in existence on the date hereof.

                              SECTION 5. COVENANTS

            Novellus covenants and agrees with the Administrative Agent and the
Lenders that, from and after the date of this Agreement until the Obligations
shall have been paid in full and the Revolving Commitments shall have
terminated:

      5.1   Maintenance of Perfected Security Interest; Further Documentation.

<PAGE>

                                                                               7

            (a) Novellus shall maintain the security interest created by this
Agreement as a perfected security interest having at least the priority
described in Section 4.2 and shall defend such security interest against the
claims and demands of all Persons whomsoever. Novellus will not (i) except as
provided for in the Securities Account Control Agreement, sell, assign,
transfer, exchange, or otherwise dispose of, or grant any option with respect
to, the Collateral, or (ii) create, incur or permit to exist any Lien or option
in favor of, or any claim of any Person with respect to, any of the Collateral,
or any interest therein, except for the Lien created by this Agreement.

      (b)   Except to the extent otherwise available to the Administrative
Agent, Novellus will furnish to the Administrative Agent from time to time
statements and schedules further identifying and describing the assets and
property constituting the Collateral and such other reports in connection
therewith as the Administrative Agent may reasonably request, all in reasonable
detail.

      (c)   At any time and from time to time, upon the written request of the
Administrative Agent, and at the sole expense of Novellus, Novellus will
promptly and duly execute and deliver, and have recorded, such further
instruments and documents and take such further actions as the Administrative
Agent may reasonably request for the purpose of obtaining or preserving the full
benefits of this Agreement and of the rights and powers herein granted,
including, without limitation, (i) filing any financing or continuation
statements under the Uniform Commercial Code (or other similar laws) in effect
in any jurisdiction with respect to the security interests created hereby and
(ii) taking any actions necessary to enable the Administrative Agent to obtain
"control" (within the meaning of the applicable Uniform Commercial Code) with
respect thereto.

      5.2   Notices.

            Novellus will advise the Administrative Agent and the Lenders
promptly, in writing and in reasonable detail, of:

      (a)   any Lien (other than security interests created hereby) on any of
the Collateral; and

      (b)   the occurrence of any other event which could reasonably be expected
to have a material adverse effect on the aggregate value of the Collateral or on
the security interests created hereby.

                         SECTION 6. REMEDIAL PROVISIONS

      6.1   Code and Other Remedies.

            Unless an Event of Default shall have occurred and be continuing,
the Administrative Agent shall not deliver a Notice of Sole Control to the
Securities Intermediary. If an Event of Default shall occur and be continuing,
the Administrative Agent may, on behalf of the Lenders, (a) deliver a Notice of
Sole Control to the Securities Intermediary and (b) exercise, in addition to all
other rights and

<PAGE>

                                                                               8

remedies granted to them in this Agreement and in any other instrument or
agreement securing, evidencing or relating to the Obligations, all rights and
remedies of a secured party under the New York UCC or any other applicable law.
Without limiting the generality of the foregoing, the Administrative Agent,
without demand of performance or other demand, presentment, protest,
advertisement or notice of any kind (except any notice required by law referred
to below) to or upon Novellus or any other Person (all and each of which
demands, defenses, advertisements and notices are hereby waived), may in such
circumstances forthwith collect, receive, appropriate and realize upon the
Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give
option or options to purchase, or otherwise dispose of and deliver the
Collateral or any part thereof (or contract to do any of the foregoing), in one
or more parcels at public or private sale or sales, at any exchange, broker's
board or office of the Administrative Agent or any Lender or elsewhere upon such
terms and conditions as it may deem advisable and at such prices as it may deem
best, for cash or on credit or for future delivery without assumption of any
credit risk. The Administrative Agent or any Lender shall have the right upon
any such public sale or sales, and, to the extent permitted by law, upon any
such private sale or sales, to purchase the whole or any part of the Collateral
so sold, free of any right or equity of redemption in Novellus, which right or
equity is hereby waived and released. The Administrative Agent shall apply the
net proceeds of any action taken by it pursuant to this Section 6.1, after
deducting all reasonable costs and expenses of every kind incurred in connection
therewith or incidental to the care or safekeeping of any of the Collateral or
in any way relating to the Collateral or the rights of the Administrative Agent
and the Lenders hereunder, including, without limitation, reasonable attorneys'
fees and disbursements, to the payment in whole or in part of the Obligations,
in such order as the Administrative Agent may elect, and only after such
application and after the payment by the Administrative Agent of any other
amount required by any provision of law, including, without limitation, Section
9-615(a)(3) of the New York UCC, need the Administrative Agent account for the
surplus, if any, to Novellus. To the extent permitted by applicable law,
Novellus waives all claims, damages and demands it may acquire against the
Administrative Agent or any Lender arising out of the exercise by them of any
rights hereunder. If any notice of a proposed sale or other disposition of
Collateral shall be required by law, such notice shall be deemed reasonable and
proper if given at least 10 days before such sale or other disposition.

      6.2   Deficiency.

            Novellus shall remain liable for any deficiency if the proceeds of
any sale or other disposition of the Collateral are insufficient to pay its
Obligations and the fees and disbursements of any attorneys employed by the
Administrative Agent or any Lender to collect such deficiency.

                      SECTION 7. THE ADMINISTRATIVE AGENT

      7.1   Administrative Agent's Appointment as Attorney-in-Fact, etc.

            (a) Novellus hereby irrevocably constitutes and appoints the
Administrative Agent and any officer or agent thereof, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead of Novellus and in the name of
Novellus or in its own name, for the purpose of carrying out the terms of this
Agreement, to take any and all appropriate action and to execute any and all
documents and instruments which may be necessary or desirable to accomplish the
purposes of this Agreement, and, without limiting the generality of the
foregoing, Novellus hereby gives the Administrative Agent the power and right,
on behalf of Novellus, without notice to or assent by Novellus, to do any or all
of the following:

<PAGE>

                                                                               9

            (i)   pay or discharge taxes and Liens levied or placed on or
      threatened against the Collateral, effect any repairs or any insurance
      called for by the terms of this Agreement and pay all or any part of the
      premiums therefor and the costs thereof;

            (ii)  execute, in connection with any sale provided for in Section
      6.1, any indorsements, assignments or other instruments of conveyance or
      transfer with respect to the Collateral; and

            (iii) (1) direct any party liable for any payment under any of the
      Collateral to make payment of any and all moneys due or to become due
      thereunder directly to the Administrative Agent or as the Administrative
      Agent shall direct; (2) ask or demand for, collect, and receive payment of
      and receipt for, any and all moneys, claims and other amounts due or to
      become due at any time in respect of or arising out of any Collateral; (3)
      commence and prosecute any suits, actions or proceedings at law or in
      equity in any court of competent jurisdiction to collect the Collateral or
      any portion thereof and to enforce any other right in respect of any
      Collateral; (4) defend any suit, action or proceeding brought against
      Novellus with respect to any Collateral; (5) settle, compromise or adjust
      any such suit, action or proceeding and, in connection therewith, give
      such discharges or releases as the Administrative Agent may deem
      appropriate; and (6) generally, sell, transfer, pledge and make any
      agreement with respect to or otherwise deal with any of the Collateral as
      fully and completely as though the Administrative Agent were the absolute
      owner thereof for all purposes, and do, at the Administrative Agent's
      option and Novellus' expense, at any time, or from time to time, all acts
      and things which the Administrative Agent deems necessary to protect,
      preserve or realize upon the Collateral and the Administrative Agent's and
      the Lenders' security interests therein and to effect the intent of this
      Agreement, all as fully and effectively as Novellus might do.

      Anything in this Section 7.1(a) to the contrary notwithstanding, the
Administrative Agent agrees that it will not exercise any rights under the power
of attorney provided for in this Section 7.1(a) unless an Event of Default shall
have occurred and be continuing.

            (b)   If Novellus fails to perform or comply with any of its
agreements contained herein, the Administrative Agent, at its option, but
without any obligation so to do, may perform or comply, or otherwise cause
performance or compliance, with such agreement.

            (c)   The expenses of the Administrative Agent incurred in
connection with actions undertaken as provided in this Section 7.1, together
with interest thereon at a rate per annum equal to the highest rate per annum at
which interest would then be payable on any category of past due ABR Loans under
the Credit Agreement, from the date of payment by the Administrative Agent to
the date reimbursed by Novellus, shall be payable by Novellus to the
Administrative Agent on demand.

            (d)   Novellus hereby ratifies all that said attorneys shall
lawfully do or cause to be done by virtue hereof. All powers, authorizations and
agencies contained in this Agreement are coupled with an interest and are
irrevocable until this Agreement is terminated and the security interests
created hereby are released.

            7.2   Duty of Administrative Agent.

                  The Administrative Agent's sole duty with respect to the
custody, safekeeping and physical preservation of the Collateral in its
possession, under Section 9-207 of the New York UCC or otherwise, shall be to
deal with it in the same manner as the Administrative Agent deals with similar
property for its own account. Neither the Administrative Agent, any Lender nor
any of their respective officers, directors, employees or agents shall be liable
for failure to demand, collect or realize upon any of the Collateral or for any
delay in doing so or shall be under any obligation to sell or otherwise dispose
of

<PAGE>

                                                                              10

any Collateral upon the request of Novellus or any other Person or to take any
other action whatsoever with regard to the Collateral or any part thereof. The
powers conferred on the Administrative Agent and the Lenders hereunder are
solely to protect the Administrative Agent's and the Lenders' interests in the
Collateral and shall not impose any duty upon the Administrative Agent or any
Lender to exercise any such powers. The Administrative Agent and the Lenders
shall be accountable only for amounts that they actually receive as a result of
the exercise of such powers, and neither they nor any of their officers,
directors, employees or agents shall be responsible to Novellus for any act or
failure to act hereunder, except for their own gross negligence or willful
misconduct.

            7.3   Execution of Financing Statements.

                  Pursuant to any applicable law, Novellus authorizes the
Administrative Agent to file or record financing statements and other filing or
recording documents or instruments with respect to the Collateral without the
signature of Novellus in such form and in such offices as the Administrative
Agent determines appropriate to perfect the security interests of the
Administrative Agent under this Agreement.

            7.4   Authority of Administrative Agent.

                  Novellus acknowledges that the rights and responsibilities of
the Administrative Agent under this Agreement with respect to any action taken
by the Administrative Agent or the exercise or non-exercise by the
Administrative Agent of any option, voting right, request, judgment or other
right or remedy provided for herein or resulting or arising out of this
Agreement shall, as between the Administrative Agent and the Lenders, be
governed by the Credit Agreement and by such other agreements with respect
thereto as may exist from time to time among them, but, as between the
Administrative Agent and Novellus, the Administrative Agent shall be
conclusively presumed to be acting as agent for the Lenders with full and valid
authority so to act or refrain from acting, and Novellus shall not be under any
obligation, or entitlement, to make any inquiry respecting such authority.

                            SECTION 8. MISCELLANEOUS

            8.1   Amendments in Writing.

                  None of the terms or provisions of this Agreement may be
waived, amended, supplemented or otherwise modified except in accordance with
Section 9.1 of the Credit Agreement.

            8.2   Notices.

                  All notices, requests and demands to or upon the
Administrative Agent or Novellus hereunder shall be effected in the manner
provided for in Section 9.2 of the Credit Agreement.

            8.3   No Waiver by Course of Conduct; Cumulative Remedies.

                  Neither the Administrative Agent nor any Lender shall by any
act (except by a written instrument pursuant to Section 8.1), delay, indulgence,
omission or otherwise be deemed to have waived any right or remedy hereunder or
to have acquiesced in any Default or Event of Default. No failure to exercise,
nor any delay in exercising, on the part of the Administrative Agent or any
Lender, any right, power or privilege hereunder shall operate as a waiver
thereof. No single or partial exercise of any right, power or privilege
hereunder shall preclude any other or further exercise thereof or the exercise
of any other right, power or privilege. A waiver by the Administrative Agent or
any Lender of any right or remedy hereunder on any one occasion shall not be
construed as a bar to any right or remedy which the Administrative Agent or such
Lender would otherwise have on any future occasion. The rights and

<PAGE>

                                                                              11

remedies herein provided are cumulative, may be exercised singly or concurrently
and are not exclusive of any other rights or remedies provided by law.

            8.4   Enforcement Expenses; Indemnification.

                  (a) Novellus agrees to pay or reimburse each Lender and the
Administrative Agent for all its costs and expenses incurred in connection with
the maintenance and operation of the Securities Account, collecting against
Novellus under the guarantee contained in Section 2 or otherwise enforcing or
preserving any rights under this Agreement and the other Loan Documents to which
Novellus is a party, including, without limitation, the fees and disbursements
of counsel (including the allocated fees and expenses of in-house counsel) to
each Lender and of counsel to the Administrative Agent.

            (b)   Novellus agrees to pay, and to save the Administrative Agent
and the Lenders harmless from, any and all liabilities with respect to, or
resulting from any delay in paying, any and all stamp, excise, sales or other
taxes which may be payable or determined to be payable with respect to any of
the Collateral or in connection with any of the transactions contemplated by
this Agreement.

            (c)   Novellus agrees to pay, and to save the Administrative Agent
and the Lenders harmless from, any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever with respect to the execution, delivery,
enforcement, performance and administration of this Agreement to the extent the
