                              THE REVOLVING LOANS

    II.1.  THE REVOLVING LOANS.

         (a)  The Commitment.  Bank agrees, on the terms and conditions 
hereinafter set forth, to make loans ("Revolving Loans") to Borrower from time
to time during the period from the date hereof to and including the Maturity
Date in the aggregate principal amount not to exceed at any one time outstanding
the Commitment, as such amount may be reduced pursuant to Section 2.1(e). Each
Revolving Loan shall be in a minimum amount of $1,000,000 and in an integral
multiple of $100,000 above such amount for a Prime Rate Loan and in a minimum
amount of $1,000,000 and in an integral multiple of $500,000 above such amount
for a Eurodollar Rate Loan. Within the limits of each Commitment, Borrower may
borrow, repay pursuant to Section 2.2(b) and reborrow under this Section,
provided that at no time shall the aggregate principal amount of outstanding
Revolving Loans exceed the Commitment then in effect.

         (b)  Making the Revolving Loans.  Borrower may borrow under the 
Commitment on any Business Day if the Revolving Loan is to be a Prime Rate Loan
and on any Eurodollar Business Day if the Revolving Loan is to be a Eurodollar
Rate Loan, provided Borrower shall give Bank irrevocable notice in the form of
Exhibit A (which notice 


                                      -10-
<PAGE>   14
must be received by Bank prior to 9:00 A.M., San Francisco time) (i) three
Eurodollar Business Days prior to the requested borrowing date in the case of a
Eurodollar Rate Loan, and (ii) on the Business Day of the requested borrowing in
the case of a Prime Rate Loan, specifying (A) the amount of the proposed
Revolving Loan, (B) the requested date of the Revolving Loan, (C) whether the
Revolving Loan is to consist of a Prime Rate Loan or a Eurodollar Rate Loan, and
(D) if the Revolving Loan is to be a Eurodollar Rate Loan, the length of the
Interest Period therefor. Upon satisfaction of the applicable conditions set
forth in this Section and in Article IV, the proceeds of such Revolving Loan
will then be made available to Borrower by Bank by crediting the account of
Borrower on the books of Bank, or as otherwise directed by Borrower.

         The notice of Revolving Loan may be given orally (including 
telephonically) or in writing (including telex or facsimile transmission) and
any conflict regarding a notice or between an oral notice and a written notice
applicable to the same Revolving Loan shall be conclusively determined by Bank's
books and records. Bank shall not incur any liability to Borrower in acting upon
any notice of Revolving Loan which Bank believes in good faith to have been
given by a Person duly authorized to give such notice on behalf of Borrower.

         (c)  Arrangement Fee.  Borrower agrees to pay to Bank, on the date of 
Borrower's execution of this Agreement, the arrangement fee specified in the
letter from Bank to Borrower, dated October 26, 1995.

         (d)  Commitment Fee.  Borrower agrees to pay to Bank a commitment fee 
equal to 0.10% per annum of the maximum amount of the Commitment (whether or not
used), which shall be calculated on the basis of a 365-day year for the actual
days elapsed, payable quarterly in arrears on the last day of each December,
March, June, and September, commencing the first such date occurring after the
date of this Agreement, and on the Maturity Date.

         (e)  Reduction of the Commitment.  Borrower shall have the right, upon 
at least two (2) Business Days' notice to Bank, to terminate in whole or reduce
in part the unused portion of the Commitment, without premium or penalty,
provided that each partial reduction shall be in the aggregate amount of
$1,000,000 or an integral multiple of $1,000,000 thereof and that such reduction
shall not reduce the Commitment to an amount less than the amount 


                                      -11-
<PAGE>   15
outstanding hereunder on the effective date of the reduction. Such notice shall
be irrevocable and such reduction shall not be reinstated.

         (f)  Revolving Note.  The Revolving Loans made by Bank pursuant hereto 
shall be evidenced by a promissory note of Borrower, substantially in the form
of Exhibit B, with appropriate insertions (the "Revolving Note"), payable to the
order of Bank and representing the obligation of Borrower to pay the aggregate
unpaid principal amount of the Revolving Loans made by Bank to Borrower, with
interest thereon as prescribed in Section 2.3. Bank is hereby authorized to
record in its books and records and on any exhibit annexed to Revolving Note,
the date and amount of each Revolving Loan made by Bank and the date and amount
of each payment of principal thereof, and in the case of Eurodollar Rate Loans,
the Interest Period and interest rate with respect thereto, and any such
recordation shall constitute prima facie evidence of the accuracy of the
information so recorded; provided that failure by Bank to effect such
recordation shall not affect Borrower's obligations hereunder. Prior to the
transfer of the Revolving Note, Bank shall record such information on any
exhibit annexed to and forming a part of the Revolving Note.

         (g)  Non-Utilization Fee.  Borrower agrees to pay to Bank a 
non-utilization fee on the average daily unused portion of the Commitment from
the date of this Agreement until the Maturity Date, or any extensions thereof,
at the rate of 0.10% per annum, which shall be calculated on the basis of a
365-day year for the actual days elapsed, payable on the last day of each
December, March, June, and September (for the preceding quarter) commencing the
first such date occurring after the date of this Agreement and on the Maturity
Date.

         (h)  Extension of Maturity Date.  Notwithstanding anything to the 
contrary contained in this Agreement, the Maturity Date may be extended for
additional one year periods on each anniversary date of this Agreement. A
request for an extension of the Maturity Date may be made by Borrower not more
than 60 nor less than 30 days prior to each anniversary of the date of this
Agreement. Within 15 days of its receipt of a request by Borrower to extend the
Maturity Date, Bank shall notify Borrower whether it agrees to the requested
extension of the Maturity Date (which decision shall be in the absolute
discretion of Bank). The failure by Bank to respond to any extension request
within the applicable period, shall be deemed a 



                                      -12-
<PAGE>   16
rejection of such request. Each extension of the Maturity Date agreed to by Bank
shall be evidenced by an amendment to this Agreement. In connection with the
making of any request for an extension of the Maturity Date, Borrower shall
provide to Bank any documents, instruments, records, information, or access to
management personnel that Bank may reasonably request.

    II.2.     REPAYMENT.

         (a)  Mandatory Repayments. The aggregate principal amount of the 
Revolving Loans outstanding on the Maturity Date, together with accrued interest
thereon, shall be due and payable in full on the Maturity Date. If at any time
the aggregate principal amount of outstanding Revolving Loans exceeds the
Commitment then in effect, Borrower shall immediately repay the Revolving Loans
in an amount equal to the excess.

         (b)  Optional Payment.  Borrower may at its option repay the Revolving 
Loans, without penalty except as set forth in Section 3.7(b), in whole or in
part, on any Business Day, prior to the Maturity Date, from time to time,
provided Bank shall have received from Borrower notice of any such payment at
least: (i) three Business Days prior to the date of the proposed payment if the
Revolving Loan being prepaid is a Eurodollar Rate Loan, and (ii) one Business
Day prior to the date of the proposed payment if the Revolving Loan being
prepaid is a Prime Rate Loan. For Prime Rate Loans, each day shall be defined as
and constitute an "Interest Period." Partial payments hereunder shall be in an
aggregate principal amount of not less than the lesser of (a) $1,000,000 and in
an integral multiple of $100,000 for a Revolving Loan consisting of a Prime Rate
Loan; (b) $1,000,000 and in an integral multiple of $500,000 for a Revolving
Loan consisting of a Eurodollar Rate Loan; and (c) the outstanding balance of
the Revolving Loan being paid.

         (c)  Allocation of Payments Following an Event of Default.  Following 
the occurrence of an Event of Default and acceleration of the Revolving Loans,
all amounts received by Bank on account of the Revolving Loans shall be applied
by Bank as follows:

              (i)   First, to the payment of expenses incurred by Bank in the 
enforcement of its rights under the Loan Documents, including, without
limitation, all costs and expenses of collection, attorneys' fees and 


                                      -13-
<PAGE>   17
court costs; and

              (ii)  then, to the outstanding principal balance of all Revolving 
Loans and interest accrued thereon.

    II.3.     INTEREST RATE AND PAYMENT DATES.

         (a)  Payment of Interest.  Interest with respect to each Revolving Loan
shall be payable in arrears on each Interest Payment Date for such Revolving
Loan. In no event shall interest on a Revolving Loan exceed the maximum rate
permitted by applicable law.

         (b)  Prime Rate Loans.  Revolving Loans which are Prime Rate Loans 
shall bear interest on the unpaid principal amount thereof at a rate per annum
equal to the Prime Rate from the date hereof through the Maturity Date. Bank
shall promptly notify Borrower of the amount and the effective date of each
adjustment in the Prime Rate, provided that no failure or delay in giving any
such notice shall affect or delay the making of any such adjustments or the
obligation of Borrower to pay in a timely manner the interest due on such
Revolving Loans.

         (c)  Eurodollar Rate Loans.  Revolving Loans which are Eurodollar Rate 
Loans shall bear interest for each Interest Period with respect thereto on the
unpaid principal amount thereof at a rate per annum equal to the Eurodollar Rate
determined for such Interest Period plus 0.625 percentage points.

    II.4.     CONTINUATION AND CONVERSION OPTIONS. Borrower may elect from time 
to time to convert outstanding Revolving Loans from Revolving Loans bearing
interest at a rate determined by reference to one basis to Revolving Loans
bearing interest at a rate determined by reference to an alternative basis if
Borrower gives Bank (i) at any time irrevocable notice of an election to convert
Eurodollar Rate Loans to Prime Rate Loans and (ii) at least three Eurodollar
Business Days' prior irrevocable notice of an election to convert Prime Rate
Loans to Eurodollar Rate Loans, provided that any conversion of Eurodollar Rate
Loans to Prime Rate Loans shall only be made on the last day of an Interest
Period with respect thereto, and provided further that no Prime Rate Loan may be
converted to a Eurodollar Rate Loan so long as an Event of Default or Potential
Event of Default has occurred and is continuing. Borrower may elect from time to
time to 


                                      -14-
<PAGE>   18
continue its outstanding Eurodollar Rate Loans upon the expiration of the
Interest Period(s) applicable thereto if Borrower gives to Bank irrevocable
notice of continuation of such a Eurodollar Rate at least one Eurodollar
Business Days' prior to the expiration thereof and so long as an Event of
Default or Potential Event of Default has not occurred and is not continuing.
Each notice electing to convert or continue a Revolving Loan shall specify: (i)
the proposed conversion/continuation date; (ii) the amount of the Revolving Loan
to be converted/continued; (iii) the nature of the proposed
continuation/conversion; and (iv) in the case of a conversion to, or
continuation of a Eurodollar Rate Loan, the requested Interest Period, and shall
certify that no Event of Default or Potential Event of Default has occurred and
is continuing. On the date on which such conversion or continuation is being
made Bank shall take such action as is necessary to effect such conversion or
continuation. In the event that no notice of continuation or conversion is
received by Bank with respect to outstanding Eurodollar Rate Loans, upon
expiration of the Interest Period(s) applicable thereto, such Eurodollar Rate
Loans shall convert to Prime Rate Loans. Subject to the limitations set forth in
this Section and in the definition of Interest Period, all or any part of
outstanding Revolving Loans may be converted or continued as provided herein,
provided that partial conversions or continuations shall be in an aggregate
principal amount of not less than (a) $1,000,000 and in an integral multiple of
$100,000 for a Revolving Loan consisting of a Prime Rate Loan; (b) $1,000,000
and in an integral multiple of $500,000 above such amount for a Eurodollar Rate
Loan; and (c) the outstanding balance of the Revolving Loan being converted or
continued.

                                       III

               GENERAL PROVISIONS CONCERNING THE REVOLVING LOANS

    III.1.    USE OF PROCEEDS.  The proceeds of the Revolving Loans hereunder 
shall be used by Borrower for general corporate purposes.

    III.2.    POST MATURITY INTEREST. Notwithstanding anything to the contrary
contained in Section 2.3, if all or a portion of the principal amount of any of
the Revolving Loans made hereunder or any interest accrued thereon shall not be
paid when due (whether at the stated maturity, by acceleration or otherwise),
any such overdue 


                                      -15-
<PAGE>   19
amount shall bear interest at a rate per annum which is equal to the greater of
(a) two percent (2%) above the rate which would otherwise be applicable pursuant
to Section 2.3 and (b) two percent (2%) above the Prime Rate, from the date of
such nonpayment until paid in full (after as well as before judgment), payable
on demand. In addition, such Revolving Loan, if a Eurodollar Rate Loan, shall be
converted to a Prime Rate Loan at the end of the then current Interest Period
therefor.

    III.3.    COMPUTATION OF INTEREST

         (a)  Calculations.  Interest in respect of the Prime Rate Loans shall 
be calculated on the basis of a 365-day year for the actual days elapsed. Any
change in the interest rate on a Prime Rate Loan resulting from a change in the
Prime Rate shall become effective as of the opening of business on the date on
which such change in the Prime Rate shall become effective. Interest with
respect of the Eurodollar Rate Loans shall be calculated on the basis of a
360-day year for the actual days elapsed.

         (b)  Determination by Bank.  Each determination of an interest rate or 
fee by Bank pursuant to any provisions of this Agreement shall be conclusive and
binding on Borrower in the absence of manifest error.

    III.4.    PAYMENTS. Borrower shall make each payment of principal, interest,
and fees referred to in Section 2.2 due from it hereunder and under the
Revolving Note, without setoff or counterclaim, not later than 12:00 P.M. (San
Francisco time) on the day when due in lawful money of the United States of
America to Bank, at the office of Bank designated from time to time in
immediately available funds.

    III.5.    PAYMENT ON NON-BUSINESS DAYS. Whenever any payment to be made
hereunder or under the Revolving Note shall be stated to be due on a day which
is not a Business Day, such payment may be made on the next succeeding Business
Day and with respect to payments of principal, interest thereon shall be payable
at the then applicable rate during such extension.

    III.6.    REDUCED RETURN. If Bank shall have determined that any new or
additional applicable law, regulation, rule, or regulatory requirement
(collectively in this Section 3.6 "Requirement") regarding capital 


                                      -16-
<PAGE>   20
adequacy, or any change therein, or any change in the interpretation or
administration thereof by any governmental authority, central bank, or
comparable agency charged with the interpretation of administration thereof, or
compliance by Bank with any new or additional request or directive regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank, or comparable agency, has or would have the effect of reducing the
rate of return on Bank's capital as a consequence of the Commitment and
obligations hereunder to a level below that which would have been achieved but
for such Requirement, change, or compliance (taking into consideration Bank's
policies with respect to capital adequacy) by an amount deemed by Bank to be
material (which amount shall be determined by Bank's reasonable allocation of
the aggregate of such reductions resulting from such events), then from time to
time, within thirty (30) Business Days after written demand by Bank, Borrower
shall pay to Bank such additional amount or amounts as will compensate Bank for
such reduction. Notwithstanding the foregoing, no additional compensation will
be required from Borrower under this Section 3.6 if the reason for additional
compensation was based solely on Bank's failure to comply with any existing or
new law, treaty, rule, or regulation or requirement. In addition, Bank shall
promptly notify Borrower of any proposed request for compensation under this
Section 3.6 and shall provide Borrower with reasonable support therefor. Any
request by Bank for additional compensation shall be structured to allocate such
additional costs over the term of the credit affected thereby.

    III.7.    INDEMNITIES.

         (a)  General.  Whether or not the transactions contemplated hereby 
shall be consummated, Borrower agrees to indemnify, pay and hold Bank, and the
shareholders, officers, directors, employees, and agents of Bank, harmless from
and against any and all claims, liabilities, losses, damages, costs, and
expenses (whether or not any of the foregoing Persons is a party to any
litigation), including, without limitation, reasonable attorneys' fees and costs
(including, without limitation, the reasonable estimate of the allocated cost of
in-house legal counsel and staff) and costs of investigation, document
production, attendance at a deposition, or other discovery, with respect to or
arising out of any proposed acquisition by Borrower or any of its Consolidated
Subsidiaries of any Person or any securities (including a self-tender), this
Agreement or any use of proceeds 


                                      -17-
<PAGE>   21
hereunder, or any claim, demand, action or cause of action being asserted
against Borrower or any of its Consolidated Subsidiaries (collectively, the
"Indemnified Liabilities"), provided that Borrower shall have no obligation
hereunder with respect to Indemnified Liabilities arising from the gross
negligence or willful misconduct of any such Persons. If any claim is made, or
any action, suit or proceeding is brought, against any Person indemnified
pursuant to this Section, the indemnified Person shall notify Borrower of such
claim or of the commencement of such action, suit or proceeding, and Borrower
will assume the defense of such action, suit or proceeding, employing counsel
selected by Borrower and reasonably satisfactory to the indemnified Person, and
pay the fees and expenses of such counsel. This covenant shall survive
termination of this Agreement and payment of the outstanding Revolving Note.

         (b)  Funding Losses.  Borrower agrees to indemnify Bank and to hold 
Bank harmless from any loss or expense including, but not limited to, any such
loss or expense arising from interest or fees payable by Bank to lenders of
funds obtained by Bank in order to maintain its Eurodollar Rate Loans hereunder,
which Bank may sustain or incur as a consequence of (i) default by Borrower in
payment of the principal amount of or interest on the Eurodollar Rate Loans of
Bank, (ii) default by Borrower in making a conversion or continuation after
Borrower has given a notice thereof, (iii) default by Borrower in making any
payment after Borrower has given a notice of payment or (iv) Borrower making any
payment of a Eurodollar Rate Loan on a day other than the last day of the
Interest Period for such Revolving Loan. For purposes of this Section and
Section 3.10, it shall be assumed that Bank had funded or would have funded one
hundred percent (100%) of each Eurodollar Rate Loan in the interbank Eurodollar
market for a corresponding amount and term. In the event of a payment set forth
in (iv) above, Borrower shall be credited with a reinvestment interest rate
equal to one sixteenth of one percent (.0625%) less than the rate of interest
generally available to Bank at the time of the payment for a period of time
approximately equal to the period remaining on the then applicable Interest
Period and for an amount approximately equal to the amount of the payment. The
determination of such amount by Bank shall be presumed correct in the absence of
manifest error. This covenant shall survive termination of this Agreement and
payment of the outstanding Revolving Note.

    III.8.    FUNDING SOURCES. Nothing in this Agreement 


                                      -18-
<PAGE>   22
shall be deemed to obligate Bank to obtain the funds for any Revolving Loan in
any particular place or manner or to constitute a representation by Bank that it
has obtained or will obtain the funds for any Revolving Loan in any particular
place or manner.

    III.9.    INABILITY TO DETERMINE INTEREST RATE. In the event that Bank shall
have determined (which determination shall be conclusive and binding upon
Borrower) that by reason of circumstances affecting the interbank Eurodollar
market, adequate and reasonable means do not exist for ascertaining the
Eurodollar Rate applicable pursuant to Section 2.3 for any Interest Period with
respect to a Eurodollar Rate Loan that will result from a requested Eurodollar
Rate Loan or that such rate of interest does not adequately cover the cost of
funding such Revolving Loan, Bank shall forthwith give notice of such
determination to Borrower not later than 1:00 P.M., San Francisco time, on the
requested Borrowing date, the requested conversion date or the last day of an
Interest Period of a Revolving Loan which was to have been continued as a
Eurodollar Rate Loan. If such notice is given and has not been withdrawn (i) any
requested Eurodollar Rate Loan shall be made as a Prime Rate Loan, or, at
Borrower's option, such Revolving Loan shall not be made, (ii) any Revolving
Loan that was to have been converted to a Eurodollar Rate Loan, shall be
continued as, or converted into, a Prime Rate Loan and (iii) any outstanding
Eurodollar Rate Loan shall be converted, on the last day of the then current
Interest Period with respect thereto, to a Prime Rate Loan. Until such notice
has been withdrawn by Bank, no further Eurodollar Rate Loans shall be made and
Borrower shall not have the right to convert a Revolving Loan to a Eurodollar
Rate Loan. Bank will review the circumstances affecting the interbank Eurodollar
market from time to time and Bank will withdraw such notice at such time as it
shall determine that the circumstances giving rise to said notice no longer
exist.

    III.10.   REQUIREMENTS OF LAW. In the event that any law, regulation, or
directive or any change therein or in the interpretation or application thereof
or compliance by Bank with any request or directive (whether or not having the
force of law) from any central bank or other governmental authority, agency or
instrumentality:

         (a)  does or shall subject Bank to any new or additional tax of any 
kind whatsoever with respect to this Agreement, the Revolving Note, or any
Revolving Loan made hereunder, or change the basis of taxation of payments to


                                      -19-
<PAGE>   23
Bank of principal, commitment fee, non-utilization fee, interest, or any other
amount payable hereunder (except for changes in the rate of tax on the overall
net income of Bank);

         (b)  does or shall impose, modify, or hold applicable any reserve, 

assessment rate, special deposit, compulsory loan, or other requirement
(collectively in this Section 3.10 "Requirements") against assets held by, or
deposits or other liabilities in or for the account of, advances or loans by, or
other credit extended by, or any other acquisition of funds by, any office of
Bank which Requirements are not otherwise included in the determination of any
Eurodollar Rate at the last Borrowing conversion or continuation date of a
Revolving Loan;

         (c)  does or shall impose, modify or hold applicable any of the 
Requirements against the Commitment; or

         (d)  does or shall impose on Bank any other new or additional 
condition; 

and the result of any of the foregoing is to increase the cost to Bank of
making, renewing or maintaining the Commitment or the Eurodollar Rate Loans or
to reduce any amount receivable thereunder by an amount determined by Bank, in
its sole discretion, to be material (which increase or reduction shall be
determined by Bank's reasonable allocation of the aggregate of such cost
increases or reduced amounts receivable resulting from such events), then, in
any such case, Borrower shall pay to Bank, within thirty (30) Business Days of
its demand, any additional amounts necessary to compensate Bank for such
additional cost or reduced amount receivable as determined by Bank with respect
to this Agreement. If Bank becomes entitled to claim any additional amounts
pursuant to this subsection, it shall notify Borrower of the event by reason of
which it has become so entitled. A statement incorporating the calculation as to
any additional amounts payable pursuant to the foregoing sentence submitted by
Bank to Borrower shall be conclusive in the absence of manifest error.
Notwithstanding the foregoing, no additional compensation will be required from
Borrower under this Section 3.10 if the reason for said additional compensation
was based solely on Bank's failure to comply with any existing or new law,
treaty, rule, regulation, or requirement. In addition, Bank shall promptly
notify Borrower of any proposed request for compensation under this Section 3.10
and shall provide 


                                      -20-
<PAGE>   24
Borrower with reasonable support therefor. Any request by Bank for additional
compensation shall be structured to allocate such additional costs over the term
of the credit affected thereby.

    III.11.   ILLEGALITY. Notwithstanding any other provisions herein, if any 
law, regulation, treaty, or directive or any change therein or in the
interpretation or application thereof, shall make it unlawful, impossible or
impracticable for Bank to make or maintain Eurodollar Rate Loans as contemplated
by this Agreement, (a) the commitment of Bank hereunder to make Eurodollar Rate
Loans or convert Prime Rate Loans to Eurodollar Rate Loans shall forthwith be
suspended and (b) Bank's Revolving Loans then outstanding as Eurodollar Rate
Loans, if any, shall be converted automatically to Prime Rate Loans on the next
succeeding Interest Payment Date or within such earlier period as allowed by
law. Borrower hereby agrees to pay Bank, within thirty (30) Business Days of its
demand, any additional amounts necessary to compensate Bank for any costs
incurred by Bank in making any conversion in accordance with this Section,
including, but not limited to, any interest or fees payable by Bank to lenders
of funds obtained by it in order to make or maintain its Eurodollar Rate Loans
hereunder (Bank's notice of such costs, as certified to Borrower to be
conclusive absent manifest error). Notwithstanding the foregoing, no additional
compensation will be required from Borrower under this Section 3.11 if the
reason for said additional compensation was based solely on Bank's failure to
comply with any existing or new law, treaty, rule or regulation or requirement.
In addition Bank shall promptly notify Borrower of any proposed request for
compensation under this Section 3.11 and shall provide Borrower with reasonable
support therefor. Any request by Bank for additional compensation shall be
structured to allocate such additional costs over the term of the credit
affected thereby.

                                       IV

                             CONDITIONS OF LENDING

    IV.1.     CONDITIONS PRECEDENT TO INITIAL REVOLVING LOANS.  The obligation 
of Bank to make its initial Revolving Loan is subject to the conditions
precedent that:

         (a)  Bank shall have received on or before the date of this Agreement

<PAGE>   26
occasion of such Revolving Loan (including the initial Revolving Loan) shall be

Loan (a) the following statements shall be true and Bank shall have received the
notice required by Section 2.1(b), which notice shall be deemed to be a
certification by Borrower that:

              (i)   The representations and warranties contained in Section 5.1 
are correct on and as of the date of such Revolving Loan as though made on and
as of such date (except to the extent such representations and warranties
expressly refer to an earlier date, in which case they shall be true and correct
as of such earlier date and except that Section 5.1(e) shall be deemed instead

                         REPRESENTATIONS AND WARRANTIES

    V.1. REPRESENTATIONS AND WARRANTIES.  In order to induce Bank to make the 
Revolving Loans, Borrower represents and warrants as follows:

         (a)  Organization.  Borrower is duly organized, validly existing, and 
in good standing under the laws of the state of its formation. Borrower is also
duly authorized, qualified, and licensed in all applicable jurisdictions, and
under all applicable laws, regulations, ordinances, or orders of public
authorities, to carry on its business in the locations and in the manner
presently conducted, to the extent that the failure to do so could not
reasonably be expected to have a Material Adverse Effect. All of the
Subsidiaries and Consolidated Subsidiaries of Borrower and the percentage of
Borrower's 


                                      -23-
<PAGE>   27
ownership interest therein as of the date of this Agreement are identified on
Schedule 2.

         (b)  Authorization.  The execution, delivery, and performance by 
Borrower of the Loan Documents, and the making of Borrowings hereunder, are
within Borrower's corporate powers, have been duly authorized by all necessary
corporate action and do not contravene (i) Borrower's certificate of
incorporation, by-laws or other organizational documents or (ii) any law or
regulation (including Regulations G, T, U, and X) or any contractual restriction
binding on or affecting Borrower.

         (c)  Governmental Consents.  No authorization or approval or other 
action by, and no notice to or filing with, any governmental authority or
regulatory body (except routine reports required pursuant to the Securities
Exchange Act of 1934, as amended (if such act is applicable to Borrower), which
reports will be made in the ordinary course of business) is required for the due
execution, delivery, and performance by Borrower of the Loan Documents.

         (d)  Validity.  The Loan Documents are the binding obligations of 
Borrower, enforceable in accordance with their respective terms; except in each
case as such enforceability may be limited by bankruptcy, insolvency,
reorganization, liquidation, moratorium, or other similar laws of general
application and equitable principles relating to or affecting creditors' rights.

         (e)  Financial Condition.  The balance sheets of Borrower and its 
Consolidated Subsidiaries as at the fiscal quarter ended July 2, 1995 and the
fiscal year ended January 1, 1995, and the related statements of income and
retained earnings of Borrower and its Consolidated Subsidiaries to that date and
the fiscal year then ended, copies of which have been furnished to Bank, fairly
present the financial condition of Borrower and its Consolidated Subsidiaries as
at such dates and the results of the operations of Borrower and its Consolidated
Subsidiaries for the respective periods ended on such dates, all in accordance
with GAAP, consistently applied. Since January 1, 1995, there has been no
material adverse change in the business, operations, properties, assets, or
condition (financial or otherwise) of Borrower and its Consolidated
Subsidiaries, taken as a whole.

         (f)  Litigation.  Except as set forth in the 


                                      -24-
<PAGE>   28
financial statements delivered on or prior to the date hereof, to the best of
Borrower's knowledge there is no pending or threatened action or proceeding
affecting Borrower or any of its Consolidated Subsidiaries before any court,
governmental agency, or arbitrator, which may materially adversely affect the
consolidated financial condition or operations of Borrower or which may have a
material adverse effect on Borrower's ability to perform its obligations under
the Loan Documents, having regard for its other financial obligations (a
"Material Adverse Effect").

         (g)  Employee Benefit Plans.  Borrower and each of its ERISA Affiliates
is in compliance in all material respects with any applicable provisions of
ERISA and the regulations and published interpretations thereunder wish respect
to all Employee Benefit Plans. No Termination Event has occurred or is
reasonably expected to occur with respect to any Pension Plan that would
reasonably be expected to have a Material Adverse Effect.

         (h)  Disclosure.  No representation or warranty of Borrower contained 
in this Agreement or any other document, certificate, or written statement
furnished to Bank or on behalf of Borrower for use in connection with the
transactions contemplated by this Agreement contains any untrue statement of a
material fact or omits to state a material fact (known to Borrower in the case
of any document not furnished by it) necessary in order to make the statements
contained herein or therein not misleading. To the best of Borrower's knowledge,
there is no fact known to Borrower (other than matters of a general economic
nature) which materially adversely affects the business, operations, property,
assets, or condition (financial or otherwise) of Borrower and its Consolidated
Subsidiaries, taken as a whole, which has not been disclosed herein or in such
other documents, certificates and statements furnished to Bank for use in
connection with the transactions contemplated hereby.

         (i)  Margin Stock.  The aggregate value of all margin stock (as defined
in Regulation U) directly or indirectly owned by Borrower and its Consolidated
Subsidiaries is less than 25% of the aggregate value of Borrower's assets.

         (j)  Environmental Matters.  Except as set forth in the financial 
statements delivered on or prior to the date hereof and except for certain
claims associated with Great Western Chemical, neither Borrower nor any


                                      -25-
<PAGE>   29
Consolidated Subsidiary, nor, to the best of their knowledge, any other person,
has treated, stored, processed, discharged, spilled, or otherwise disposed of
any substance defined as hazardous or toxic by any applicable federal, state, or
local law, rule, regulation, order, or directive, or any waste or by-product
thereof, at any real property or any other facility owned, leased, or used by
Borrower or any Consolidated Subsidiary, in violation of any applicable
statutes, regulations, ordinances, or directives of any governmental authority
or court, which violations may result in liability to Borrower or any
Consolidated Subsidiary in an amount for all such violations that could
reasonably be expected to have a Material Adverse Effect; and the unresolved
violations, if any, set forth in the financial statements delivered on or prior
to the date hereof will not result in liability to Borrower or any Consolidated
Subsidiary in an amount for all such unresolved violations that could reasonably
be expected to have a Material Adverse Effect. Except as set forth in the
financial statements delivered on or prior to the date hereof, no employee or
other person has ever made a claim or demand against Borrower or any
Consolidated Subsidiary based on alleged damage to health caused by any such
hazardous or toxic substance or by any waste or by-product thereof in an amount
that could reasonably be expected to have a Material Adverse Effect; and the
unsatisfied claims, if any, or demands against Borrower or any Consolidated
Subsidiary set forth in the financial statements delivered on or prior to the
date hereof will not result in uninsured liability to Borrower or any
Consolidated Subsidiary or any of their respective officers, employees,
representatives, agents, or shareholders in an amount that could reasonably be
expected to have a Material Adverse Effect for all such unsatisfied claims or
demands. Except as set forth in the financial statements delivered on or prior
to the date hereof neither Borrower nor any Consolidated Subsidiary has been
charged by any governmental authority with improperly using, handling, storing,
discharging, or disposing of any such hazardous or toxic substance or waste or
by-product thereof or with causing or permitting any pollution of any body of
water in an amount that could reasonably be expected to have a Material Adverse
Effect; and the outstanding charges, if any, set forth in the financial
statements delivered on or prior to the date hereof will not result in liability
to Borrower or any Consolidated Subsidiary or any or their respective officers,
employees, representatives, agents, or shareholders in an amount that could
reasonably be expected to have a Material Adverse Effect for all such


                                      -26-
<PAGE>   30
outstanding charges.

         (k)  Employee Matters.  There is no strike or work stoppage in 
existence or, to the best of Borrower's knowledge, threatened involving Borrower
or its Consolidated Subsidiaries that could reasonably be expected to have a
Material Adverse Effect.

                                       VI

                                      VIII

                                  MISCELLANEOUS

    VIII.1.   AMENDMENTS, ETC. No amendment or waiver of any provision of the 
Loan Documents nor consent to any departure by Borrower therefrom, shall in any
event be effective unless the same shall be in writing and signed by Bank, and
then such waiver or consent shall be effective only in the specific instance and
for the specific purpose for which given.

    VIII.2.   NOTICES, ETC. Except as otherwise set forth in this Agreement, all
notices and other communications provided for hereunder shall be in writing
(including telegraphic, telex, or facsimile communication) and mailed or
telegraphed or telexed or sent by facsimile or delivered, if to Borrower, at
Borrower's address set forth on the signature page hereof; and if to Bank, at
its address set forth on the signature page hereof; or, as to each party at such
other address as shall be designated by such party in a written notice to the
other parties. All such notices and communications shall be effective when
deposited in the mails, delivered to the telegraph company, sent by telex or
sent by facsimile respectively, except that notices and communications to Bank
pursuant to Article II shall not be effective until received by Bank.

    VIII.3.   RIGHT OF SETOFF. Upon and during the continuance of any Event of
Default, Bank and any participant with Bank in the Commitment pursuant to
Section 8.6 is hereby authorized by Borrower, at any time, and from time to
time, without prior notice, (a) to set off against, and to appropriate and apply
to the payment of, the obligations and liabilities of Borrower under the 


                                      -39-
<PAGE>   43
Loan Documents (whether matured or unmatured, fixed or contingent or liquidated
or unliquidated) any and all amounts owing by Bank or such participant to
Borrower (whether payable in Dollars or any other currency, whether matured or
unmatured, and, in the case of deposits, whether general or special, time or
demand and however evidenced), and (b) pending any such action, to the extent
necessary, to hold such amounts as collateral to secure such obligations and
liabilities and to return as unpaid for insufficient funds any and all checks
and other items drawn against any deposits so held as Bank or such participant
in its sole discretion may elect. Bank agrees promptly to notify Borrower (and
to cause each such participant to notify Borrower) after any such set-off and
application is made. Upon and during the continuance of any Event of Default,
Bank and all such participants are authorized to debit any account maintained
with it by Borrower for any amount of principal, interest, or fees which are
then due and owing to Bank or such participants by Borrower.

    VIII.4.   NO WAIVER: REMEDIES. No failure on the part of Bank to exercise, 
and no delay in exercising, any right under any of the Loan Documents shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right under any of the Loan Documents preclude any other or further exercise
thereof or the exercise of any other right. The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

    VIII.5.   COSTS AND EXPENSES. Borrower agrees to pay, within 30 days of 
demand therefor by Bank (but on demand if there shall then exist any Event of
Default), all costs and expenses (i) of Bank (including reasonable and
documented attorneys' fees and reasonable and documented costs of in-house
counsel and staff) in connection with the preparation, amendment, or
modification of the Loan Documents, and (ii) of Bank in connection with the
enforcement (including, without limitation, in appellate, bankruptcy,
insolvency, liquidation, reorganization, moratorium, or other similar
proceedings) or restructuring of the Loan Documents; provided that Borrower's
obligation to reimburse Bank for such attorneys' fees in connection with the
preparation of the Loan Documents shall be limited to $5,000; provided further
that the foregoing limitation shall not apply to any such costs and expenses
attributable (in the reasonable judgment of Bank) to (i) any material change
(other than at the request of Bank) in the terms and conditions set forth in the
Summary of Terms and Conditions (attached to a letter from Bank to 


                                      -40-
<PAGE>   44
Andrew Koslow, Esq., dated October 16, 1995), dated October 16, 1995, or (ii)
any failure by Borrower, or any representative acting on behalf of Borrower
reasonably to cooperate with the efficient closing of the transaction
contemplated by the Loan Documents.

    VIII.6.   PARTICIPATIONS. (a) Bank may sell, negotiate, or grant 
participations in all or part of the obligations of Borrower outstanding under
the Loan Documents, subject to the prior written approval of Borrower (which
approval shall not be unreasonably withheld); provided that any such sale,
negotiation or participation shall be in compliance with the applicable federal
and state securities laws. Notwithstanding the foregoing, Bank shall not sell,
negotiate, or grant participations unless it retains at least $20,000,000 of the
Commitment or another amount as agreed upon by Borrower and Bank. Bank shall not
transfer or grant any participating interest under which the participant shall
have rights: (i) greater than Bank under Sections 3.6, 3.7, or 3.10 of this
Agreement, or (ii) to approve any amendment to, or any consent or waiver with
respect to, this Agreement or any other Loan Document, except to the extent such
amendment, consent or waiver would:

              (A)  increase the amount or extend the Maturity Date of the 
Commitment;

              (B)  reduce the principal of, or interest on, the Revolving Loans 
or any fee or other amount payable to the participant hereunder;

              (C)  postpone any date fixed for any payment in respect of 
principal of, or interest on, the Revolving Loans or any fee or other amount
payable to Bank hereunder; or

              (D)  amend the provisions of this sentence.

In the event that Borrower requests a modification to any of the provisions set
forth in clauses (A) through (D) above (a "Modification Request") and any
existing participant refuses to agree to such modifications (a "Nonaccepting
Participant"), Bank shall use good faith efforts to secure a participant willing
to accept such modifications as a replacement participant for the Nonaccepting
Participant (an "Accepting Participant") and, in the event that Bank shall be
unable to secure an Accepting Participant within 60 days from Bank's receipt
from Borrower of the related Modification Request, then 



                                      -41-
<PAGE>   45
Borrower shall, at its option, be entitled to purchase the Nonaccepting
Participant's participation interest. No participant shall constitute "Bank"
under any Loan Document, and Borrower shall continue to deal solely and directly
with Bank.

         (b)  Bank may disclose to any proposed participant which is a financial
institution any information relating to Borrower or any of its Consolidated
Subsidiaries; provided, that prior to such disclosure such participant and Bank
shall have executed Borrower's standard Confidential Disclosure Statement
("Confidentiality Letter").

    VIII.7.   EFFECTIVENESS, BINDING EFFECT; GOVERNING LAW. This Agreement is 
being executed on the date hereof by Borrower, and Bank and is binding on and

thereafter shall be binding upon and inure to the benefit of Borrower, Bank and
their respective permitted successors and assigns, except that Borrower shall
not have the right to assign its rights hereunder or any interest herein without
the prior written consent of Bank. THIS AGREEMENT AND THE REVOLVING NOTE SHALL
BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
CALIFORNIA WITHOUT GIVING EFFECT TO ITS CHOICE OF LAW DOCTRINE.

    VIII.8.   CONSENT TO JURISDICTION; VENUE. BANK FOR SERVICE OF PROCESS. All
judicial proceedings brought against Borrower with respect to this Agreement and
the Loan Documents may be brought in any state or federal court of competent
jurisdiction in the County of San Francisco in the State of California, and by
execution and delivery of this Agreement, Borrower accepts for itself and in
connection with its properties, generally and unconditionally, the nonexclusive
jurisdiction of the aforesaid courts, and irrevocably agrees to be bound by any
judgment rendered thereby in connection with this Agreement. Borrower
irrevocably waives any right it may have to assert the doctrine of forum non
conveniens or to object to venue to the extent any proceeding is brought in
accordance with this Section. Borrower designates and appoints Borrower's Chief
Financial Officer, from time to time, Komag Incorporated, 275 South Hillview
Drive, Milpitas, California 95035, and such other Persons as may hereafter be
selected by Borrower irrevocably agreeing in writing to so serve (as its agent
to receive on its behalf 


                                      -42-
<PAGE>   46
service of all process in any such proceedings in any such court, such service
being hereby acknowledged by Borrower to be effective and binding service in
every respect). A copy of any such process so served shall be mailed by
registered mail to Borrower at its address provided in the applicable signature
page hereto, except that unless otherwise provided by applicable law, any
failure to mail such copy shall not affect the validity of service of process.
If any agent appointed by Borrower refuses to accept service, Borrower hereby
agrees that service upon it by mail shall constitute sufficient notice. Nothing
herein shall affect the right to serve process in any other manner permitted by
law or shall limit the right of Bank, on behalf of Bank or Bank to bring
proceedings against Borrower in courts of any jurisdiction.

    VIII.9.   ENTIRE AGREEMENT. This Agreement with Exhibits and the other Loan
Documents embody the entire agreement and understanding between the parties
hereto and supersedes all prior agreements and understandings relating to the
subject matter hereof.

    VIII.10.  SEPARABILITY OF PROVISIONS. In case any one or more of the 
provisions contained in this Agreement should be invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby.

    VIII.11.  EXECUTION IN COUNTERPARTS. This Agreement may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed shall be deemed to be an original and all of
which taken together shall constitute one and the same agreement.

    VIII.12.  SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and 
inure to the benefit of the parties hereto and their respective successors and
assigns, except that Borrower may not assign or transfer any of its rights or
obligations under this Agreement or any other Loan Document without the consent
of Bank.

    VIII.13.  EFFECTIVENESS OF AGREEMENT. This Agreement shall become effective 
on the later to occur of (i) December 15, 1995 and (ii) such other date that
Borrower notifies Bank that any necessary approvals of any other lenders to
Borrower have been obtained and that this Agreement is effective, provided that
if this Agreement 


                                     -43-
<PAGE>   47
has not become effective on or before January 31, 1996 as hereinabove provided,
