ADVANCES"), or (ii) in a lawful currency other than dollars which is 
available at a branch or affiliate of the Bank located in a country other

    2.02  DOLLAR ADVANCES UNDER THE REVOLVING FACILITY.  (a)  Subject to the 
other provisions of this Section, Dollar Advances under the Revolving 
Facility shall bear interest at a rate per annum equal to the Reference Rate 
(the Reference Rate is sometimes referred to herein as the "FLOATING RATE").  
The Borrower or an Acceptable Subsidiary shall request Floating Rate Advances 
(i) by giving irrevocable written notice in the form of a Notice of Borrowing 
or (ii) by giving irrevocable oral notice by telephone in accordance with 
Section 9.10 followed promptly by facsimile confirmation in the form of a

date of the Advance. The Borrower shall pay or cause the applicable 
Acceptable Subsidiary to pay interest quarterly, on the last day of each 
calendar quarter until the Final Maturity Date, on which date all accrued and

the applicable Acceptable Subsidiary to repay the principal amount of each 
Reference Rate Advance on the Final Maturity date and on the date such 
advance is converted into an Offshore Rate Advance under subsection (b) below.

         (b) In lieu of the Floating Rate, the Borrower or the applicable 
Acceptable Subsidiary may elect during the Availability Period to have all or 
portions of Advances under the Revolving Facility bear interest at the 
Offshore Rate plus 1.0% per annum during an Offshore Rate Interest Period, 
subject to the following requirements:

              (i)   Each Offshore Rate Advance shall be for an amount not 
     less than $250,000 and multiples of $50,000 in excess thereof.

     PROVIDED, HOWEVER, that if any Interest Period for an Offshore Rate 
     Advance exceeds three months, interest shall also be payable on the date 
     which falls three months after the beginning of such 

                                       8
<PAGE>

     Interest Period and on each date which falls three months after any such 
     interest payment date. The Borrower shall repay or shall cause the 
     applicable Acceptable Subsidiary to repay the principal balance of each 
     Offshore Rate Advance on the last day of the Offshore Rate Interest 
     Period for such Advance, and (if sooner occurring) on the Final Maturity 
     Date.

              (iii)  Any payment of an Offshore Rate Advance prior to 
     the last day of the Offshore Rate Interest Period for such Advance, 
     whether voluntary, by reason of acceleration or otherwise, including any 
     mandatory payments required under this Agreement and applied by the Bank 
     to an Offshore Rate Advance, shall be accompanied by the amount of 
     accrued interest on the amount repaid and by the amount (if any) 
     required by Section 3.11.

    The Borrower or an Acceptable Subsidiary shall request Offshore Rate 
Advances by giving irrevocable written notice in the form of a Notice of 
Borrowing prior to 9:00 a.m. San Francisco time three Business Days prior to 
the requested date of the Advance.

    2.03  CONVERSION AND CONTINUATION ELECTIONS.  (a)  The Borrower or an 
Acceptable Subsidiary may, upon irrevocable written notice in the form of a 
Notice of Conversion/Continuation.

              (i)  elect, as of any Business Day, in the case of 
     Floating Rate Advances, or as of the last day of the applicable Offshore 
     Rate Interest Period, in the case of any Offshore Rate Advance, to 
     convert any such Advances (or any part thereof in an amount not less 
     than $250,000, or that is in an integral multiple of $50,000 in excess 
     thereof) into Advances of the other type; or

              (ii)  elect, as of the last day of the applicable Offshore 
     Rate Interest Period, to continue any Offshore Rate Advance having 
     Interest Periods expiring on such day (or any part thereof in an amount 
     not less than $250,000 or that is in an integral multiple of $50,000 in 
     excess thereof);

PROVIDED, that if at any time the aggregate amount of Offshore Rate Advances 
is reduced, by payment, prepayment, or conversion of part thereof to be less 
than $250,000, such Offshore Rate Advances shall automatically convert into 
Floating Rate Advances, and on and after such date the right of the Borrower 
or an Acceptable Subsidiary to continue such Advances as, and convert such 
Advances into, Offshore Rate Advances shall terminate.

         (b)  The Borrower or an Acceptable Subsidiary shall deliver a Notice 
of Conversion/Continuation to be received by the Agent not later than 9:00

the Advances are to be converted into or continued as Offshore Rate Advances; 
and (ii) on or before the Conversion/Continuation Date, if the Advances are 
to be converted into Floating Rate Loans.

         (c)  If upon the expiration of any Offshore Rate Interest Period, 
the Borrower or an Acceptable Subsidiary has failed to select timely a new 
Offshore Rate Interest Period to be applicable to such Offshore Rate 
Advances, or if any Default or Event of Default then exists, the Borrower or

to the Borrower's or the Acceptable Subsidiary's commercial letters of credit.

         (d)  In the event of any request for a drawing under a commercial 
letter of credit, the Bank will notify the Borrower.  The Borrower or the 
applicable Acceptable Subsidiary may, subject to satisfaction of all 
conditions to borrowing set forth in this Agreement, convert the amount of 
each drawing into a Reference Rate Advance (which conversion shall be deemed 
to be a new Advance).  With respect to any unreimbursed drawing which is not

Borrower's failure to satisfy the conditions set 

                                      10

forth in Section 4.02 or for any other reason, the Borrower shall reimburse

notice of the increase to the Borrower.  The Borrower shall also pay or cause

         (d)  In the event of any request for a drawing under a standby 
letter of credit, the Bank will notify the Borrower.  The Borrower or the 
applicable Acceptable Subsidiary may, subject to satisfaction of all 
conditions to borrowing set forth in this Agreement, convert the amount of 
each drawing into a Reference Rate Advance (which conversion shall be deemed 
to be a new Advance).  With respect to any unreimbursed drawing which is not 
converted into a Reference Rate Advance in whole or in part, because of the 
Borrower's failure to satisfy the conditions set forth in Section 4.02 or for 
any other reason, the Borrower shall reimburse or cause the applicable 
Acceptable Subsidiary to reimburse the Bank prior to 11:00 a.m. (San 
Francisco time), on each date that any amount is paid by the Bank under any 
standby letter of credit, in an amount equal to the amount so paid by the

Amount thereof.  Payments under this Section may be applied to the 
obligations of the Borrower or the Acceptable Subsidiaries to the Bank in the 
order and manner as the Bank in its discretion may determine; PROVIDED, 
however, that if no Default or Event of Default exists at the time of such 
payments, Borrower may designate the obligations to which such payments shall 
be applied.  Payments may also be held as cash collateral to secure letters 
of credit and may be used to prepay drafts accepted under letters of credit, 
at the Bank's option.

    2.09  INTENTIONALLY OMITTED.

    2.10  COMMITMENT FEE.  The Borrower shall pay to the Bank a commitment 
fee at the rate of .20% per annum on the average daily unused portion of the 
credit provided under this Agreement.  For purposes of computing the unused

commitment fee shall be computed on a calendar quarter basis, except for the 
first period which shall commence on the Closing Date, and end on September 
30, 1997, and the last period which shall end on the Final Maturity Date in 
respect of Advances.  The commitment fee shall be payable in arrears on 
September 30, 1997, on the last day of each successive quarter thereafter, 
and on the Final Maturity Date in respect of Advances.

and paying in full the entire amount of credit outstanding hereunder 
(including the L/C Outstanding Amount) or, in the case of a reduction of the 
commitment, that amount which is in excess of the reduced commitment, 
together with any sums due under Section 3.11.  If the commitment is 
terminated, payments shall be applied to letters of credit and drafts 
accepted under letters of credit, 

                                      13
<PAGE>

secure, the Borrower's and Acceptable Subsidiaries' obligations to the Bank 
or any Offshore Credit Provider with respect thereto.  All accrued commitment 
fees to, but not including the effective date of any termination of the 
commitment, shall be paid on the effective date of such termination.

    3.02  DISBURSEMENTS AND PAYMENTS.  Each disbursement by the Bank and each

    3.04  EVIDENCE OF INDEBTEDNESS.  Principal, interest, and all other sums 
due to the Bank (or any Offshore Credit Provider) under this Agreement shall

Credit Provider), and, if required by the Bank, by a promissory note or 
notes.  Each payment on and any other credits with respect to principal, 
interest, and all other sums due under this Agreement shall be evidenced by 
entries to records maintained by the Bank or such Offshore Credit Provider.  
The loan accounts or records maintained by the Bank or any Offshore Credit 
Provider shall be conclusive absent manifest error of the amount of the 
credit extended hereunder and the interest and payments thereon.  Any failure 
to so record or any error in doing so shall not, however, limit or otherwise 
affect the obligation of the Borrower or any Acceptable Subsidiary hereunder 
to pay any amount owing.

    3.05  INTEREST CALCULATION.  Interest based on the Reference Rate shall 
be computed on the basis of a 365/366-day year and actual days elapsed.  All 
other interest and fees payable under this Agreement shall be computed on the 
basis of a 360 day year and actual days elapsed, which results in more 
interest or a larger fee than if a 365-366 day year were used.

Acceptable Subsidiary hereunder (including unpaid interest) if not paid when 
due shall bear interest (payable on demand) from its due date until payment

interest at the rate applicable to principal.

    3.07  BUSINESS DAY.  Any sum payable by the Borrower or an Acceptable 
Subsidiary hereunder which becomes due on a day which is not a Business Day 
shall be due on the next Business Day after such due date, unless, in the 
case of an Offshore Rate Loan, the result of such extension would be to carry 
such Offshore Rate Interest Period into another calendar month, in which 
event such Offshore Rate Interest Period shall end on the immediately 
preceding Business Day.  Any payments received by the Bank or an Offshore 
Credit Provider on a day which is not a Business Day shall be deemed to be 
received on the next Business Day after such date of receipt.

    3.08  TAXES AND OTHER CHARGES.  (a) (i)  If any taxes (other than taxes 
on net income (A) imposed by the country or any subdivision of the country in 
which the Bank's or any Offshore Credit Provider's principal office or actual 
lending office is located and (B) measured by the United States taxable 
income the Bank would have received if all payments under or in respect of 
this Agreement and any instrument or agreement required hereunder were exempt 
from taxes levied by the Borrower's or the applicable Acceptable Subsidiary's 
country) are at any time imposed on any payments under or in respect of this 
Agreement or any instrument or agreement required hereunder including, but 
not limited to, payments made pursuant to this Section, the Borrower shall 
pay or shall cause the applicable Acceptable Subsidiary to pay all such taxes 
and shall also pay or cause to be paid to the Bank, at the time interest is 
paid, all additional amounts which the Bank specifies as necessary to 
preserve the after-tax yield the Bank would have received if such taxes had 
not been imposed.

                   (ii)  The additional amounts necessary to preserve the 
after-tax yield the Bank would have received if such taxes had not been 
imposed shall be calculated pursuant to the formula:

                              (w)(t)(i)
                         y = -----------
                                1-w-t

where the terms are defined as follows:

              y = additional payment to be made to the Bank

              w = withholding tax rate levied by foreign government

              t = the Bank's combined Federal and state tax rate

                                      15
<PAGE>

              i  = amount of interest to be paid on Credit (computed by using 
                   the Offshore Rate or Reference Rate or other index rate, as 
                   applicable plus the quoted margin over such rate)

              1  = one


         (b)  The Borrower will provide the Bank with original tax receipts, 
notarized copies of tax receipts, or such other documentation as will prove 
payment of tax in a court of law applying the United States Federal Rules of 
Evidence, for all taxes paid by the Borrower or an Acceptable Subsidiary 
pursuant to subsection (a) above.  The Borrower will deliver receipts to the 
Bank within 30 days after the due date for the related tax.

      3.09  ILLEGALITY.  (a)  If the Bank determines that (i) the 
introduction of any law, rule, regulation, treaty, or determination of an 
arbitrator or court or other governmental authority or any change in or in 
the interpretation or administration thereof has made it unlawful, or that 
any central bank or other governmental authority has asserted that it is 
unlawful, for the Bank (directly or through any Offshore Credit Provider) to 
make or extend any Advance or other credit under this Agreement, or (ii) any 
order, judgment, or decree of any governmental authority or arbitrator 
purports by its terms to enjoin or restrain the Bank (or any Offshore Credit 
Provider) from making or extending any Advance or other credit hereunder, 
THEN, on notice thereof by the Bank to the Borrower, the obligation of the 
Bank to make or extend such Advance or other credit (directly or through any 
Offshore Credit Provider) shall be suspended until the Bank shall have 
notified the Borrower that the circumstances giving rise to such 
determination no longer exist.

         (b)  If the Bank determines that it is unlawful for it or any 
applicable Offshore Credit Provider to maintain any Offshore Rate Advance or 
Local Currency Advance hereunder, the Borrower shall or shall cause the 
applicable Acceptable Subsidiary to prepay in full all Offshore Rate Advances 
or Local Currency Advances, as the case may be then outstanding, together 
with interest accrued thereon, either on the last day of the applicable 
Offshore Rate Interest Period or the interest period applicable to the Local 
Currency Advance if the Bank or such Offshore Credit Provider may lawfully 
continue to maintain such Advances to such day and such loans have an 
interest period, or immediately, if the Bank may not lawfully continue to 
maintain such Advances or such loans have no interest period, together with 
any amounts required to be paid in connection therewith pursuant to Section 
3.11.

    3.10  INCREASED COSTS.  (a) If the Bank determines that, due to either 
(i) the introduction of or any change (other than any 

                                      16
<PAGE>

change by way of imposition of or increase in reserve requirements included 
in the calculation of the Offshore Rate) in or in the interpretation of any 
law or regulation or (ii) the compliance by the Bank with any guideline or 
request from any central bank or other governmental authority (whether or not 
having the force of law), there shall be any increase in the cost to the Bank 
of agreeing to make or making, funding or maintaining any Offshore Rate 
Advances, then the Borrower shall be liable for, and shall from time to time, 
upon demand (with a copy of such demand to be sent to the Agent), pay to the 
Bank, additional amounts as are sufficient to compensate the Bank for such 
increased costs.

         (b)  If the Bank shall have determined that (i) the introduction of 
any Capital Adequacy Regulation, (ii) any change in any Capital Adequacy 
Regulation, (iii) any change in the interpretation or administration of any 
Capital Adequacy Regulation by any central bank or other governmental 
authority charged with the interpretation or administration thereof, or (iv) 
compliance by the Bank (or its Offshore Credit Provider) or any corporation 
controlling the Bank with any Capital Adequacy Regulation, affects or would 
affect the amount of capital required or expected to be maintained by the 
Bank or any corporation controlling the Bank and (taking into consideration 
the Bank's or such corporation's policies with respect to capital adequacy 
and the Bank's desired return on capital) determines that the amount of such 
capital is increased as a consequence of its commitment, Advances, credits or 
obligations under this Agreement, then, upon demand of the Bank to the 
Borrower, the Borrower shall pay to the Bank, from time to time as specified 
by the Bank, additional amounts sufficient to compensate the Bank for such 
increase.

    3.11  FUNDING LOSSES.  The Borrower shall reimburse the Bank and hold the 
Bank harmless from any loss or expense which the Bank may sustain or incur as 
a consequence of the failure of the Borrower (or any Acceptable Subsidiary) 
to make any payment or prepayment of principal of any Advance hereunder made 
at a rate of interest related to the Offshore Rate (including payments made 
after any acceleration thereof), or to borrow at such a rate, or the 
prepayment of an Advance which bears interest at such a rate on a day which 
is not the last day of the interest period with respect thereto (including 
payments made after any acceleration thereof or because the total amount of 
credit exceeds the limitations set forth herein), or the redenomination and 
conversion, upon the occurrence of any Event of Default, of an Advance which 
bears interest at such a rate; including any such loss or expense arising 
from the liquidation or reemployment of funds obtained by it to maintain its 
Advances made at a rate related to the Offshore Rate hereunder or from fees 
payable to terminate any deposits from which such funds were obtained or 
deemed obtained.

                                      17
<PAGE>

    3.12  INABILITY TO DETERMINE RATES.  The Bank has no obligation to accept 
an election for an Offshore Rate Advance if (a) deposits in the applicable 
currency and in the principal amount, and for the period equal to the 
interest period, for such Advance are not available in the applicable funding 
market; or (b) the Offshore Rate does not accurately reflect the cost of such 
Advance.  Nothing contained herein shall, however, obligate the Bank to 
obtain the funds for any Advance in any particular manner.

    3.13  CERTIFICATE OF THE BANK.  If the Bank claims any reimbursement or 
compensation pursuant to Section 3.10 or Section 3.11, then the Bank shall 
deliver to the Borrower a certificate setting forth in reasonable detail the 
amount payable to the Bank thereunder and such certificate shall be 
conclusive and binding on the Borrower in the absence of manifest error.

    3.14  SURVIVAL.  The agreements and obligations of the Borrower under 
Sections 3.08 through 3.11 shall survive the expiration or termination of the 
commitment to extend credit hereunder and the payment of all other 
obligations of the Borrower and the Acceptable Subsidiaries hereunder.

between or among the parties arising out of or relating to this Agreement or 
any other Credit Document or other agreements or instruments relating hereto 
or delivered in connection herewith and any claim based on or arising from an 
alleged tort, shall at the request of any party be determined by arbitration. 
The arbitration shall be conducted in accordance with the United States 
Arbitration Act (Title 9, U.S. Code), notwithstanding any choice of law 
provision in this Agreement, and under the Commercial Rules of the American 
Arbitration Association ("AAA").  The arbitration shall be conducted within 
the following California county or counties:  San Francisco.  The 
arbitrator(s) shall give effect to statutes of limitation in determining any 
claim.  Any controversy concerning whether an issue is arbitrable shall be 
determined by the arbitrator(s).  Judgment upon the arbitration award may be 
entered in any court having jurisdiction.  The institution and maintenance of 
an action for judicial relief or pursuit of a provisional or ancillary remedy 
shall not constitute a waiver of the right of any party, including the 
plaintiff, to submit the controversy or claim to arbitration if any other 
party contests such action for judicial relief.

         (b)  Notwithstanding the provisions of subsection (a) of this 
Section, no controversy or claim shall be submitted to arbitration without 
the consent of all parties if, at the time of the proposed submission, such 
controversy or claim arises from or relates to an obligation to the Bank 
which is secured by real property collateral located in California.  If all 
parties do not consent to submission of such a controversy or claim to 
arbitration, the controversy or claim shall be determined as provided in 
subsection (c) of this Section.

         (c)  A controversy or claim which is not submitted to arbitration as 
provided and limited in subsections (a) and (b) of this Section shall, at the 
request of any party, be determined by a reference in accordance with 
California Code of Civil Procedure Sections 638 ET SEQ.  If such an election 
is made, the parties shall designate to the court a referee or referees 
selected under the auspices of the AAA in the same manner as arbitrators are 
selected in AAA-sponsored proceedings.  The presiding referee of the panel, 
or the referee if there is a single referee, shall be an active attorney or 
retired judge.  Judgment upon the award rendered by such referee or referees 
shall be entered in the court in which such proceeding was commenced in 
accordance with California Code of Civil Procedure Sections 644 and 645.

         (d)  No provision of this paragraph shall limit the right of any 
party to this Agreement to exercise self-help remedies such as setoff, to 
foreclose against or sell any real or personal property collateral or

arbitration or other proceeding.  The exercise of a remedy does not waive the 
right of either party to resort to arbitration or reference.  At the Bank's 
option, foreclosure under a deed of trust or mortgage may be accomplished 
either by exercise of power of sale under the deed of trust or mortgage or by 
judicial foreclosure.

    9.10  NOTICES.  (a)  All notices, requests and other communications 
provided for hereunder shall be in writing and mailed or delivered to a party

         (c)  The Borrower acknowledges and agrees that any agreement of the 
Bank pursuant to Article II to receive notices by telephone or facsimile is 
solely for the convenience and at the request of the Borrower.  Telephone 
requests may be made by any individual identified in writing to the Bank on a 
form acceptable to the Bank as being authorized to make such requests.  The 
Bank shall be entitled to rely upon any written or telephone request from 
persons it reasonably believes to be authorized by the Borrower to make such 
requests without making independent inquiry.  The Borrower assumes the full 
risk of, and the Bank shall not be responsible for, any delays or errors in 
transmission, and the obligation of the Borrower to repay the loans and other 
extensions of credit hereunder shall not be affected in any way or to any 
extent by any failure by the Bank to receive written confirmation of any 
telephonic or facsimile notice or the receipt by the Bank of a confirmation 
which is at variance with the terms understood by the Bank to be contained in 
the telephonic or facsimile notice.

    9.11  HEADINGS; INTERPRETATION.  Article, section, and paragraph headings 
are for reference only and shall not affect the interpretation or meaning of

in any way affect or impair the legality or enforceability of the remaining 
provisions of this Agreement or any instrument or agreement required 
hereunder.

    9.13  COUNTERPARTS.  This Agreement may be executed in as many 
counterparts as may be deemed necessary or convenient, and by the different 
parties hereto on separate counterparts each of which, when so executed, 
shall be deemed an original but all such counterparts shall constitute but 
one and the same agreement.

    9.14  WAIVER OF JURY TRIAL.  IF A CONTROVERSY OR CLAIM IS NOT SUBMITTED 
TO ARBITRATION AS PROVIDED AND LIMITED IN SUBSECTIONS (a) AND (b) OF SECTION 
9.09 OR IS NOT DETERMINED BY A REFERENCE AS PROVIDED IN SUBSECTION (c) OF 
SUBSECTION 9.09, THEN THE BORROWER AND THE BANK WAIVE THEIR RESPECTIVE RIGHTS

CLAIMS, TORT CLAIMS, OR OTHERWISE.  THE BORROWER AND THE BANK EACH AGREE THAT 
ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A 
JURY.  WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR 
RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS 
TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN 
PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS AGREEMENT OR THE
