                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                            (dollar amounts in thousands)
                                     (unaudited)


1.  The interim financial statements included herein have been prepared,
    without audit, pursuant to the rules and regulations of the Securities and
    Exchange Commission.  Certain information and footnote disclosures normally
    included in financial statements prepared in accordance with generally
    accepted accounting principles have been condensed or omitted pursuant to
    such rules and regulations, although Fibreboard management believes that
    the disclosures are adequate to make the information presented not
    misleading.  These interim financial statements and notes should be read in
    conjunction with the financial statements and the notes thereto included in
    Fibreboard's 1996 Annual Report and Form 10-K.

    Interim financial statements are by necessity somewhat tentative. 
    Judgments are used to estimate the amounts recorded each quarter for items
    that are normally determinable only on an annual basis.  For example,
    numerous items relating to employee benefits are determined annually, with
    hours worked determining pension plan contributions for the year,
    eligibility for vacations, etc.  Further, all inventory quantities are
    verified by physically counting the units on hand at least once a year. 
    For those inventories not counted at the end of the quarter, quantities are
    determined using measured sales and production data for the period.

    The interim period financial information included herein reflects all
    adjustments of a normal and recurring nature which are, in the opinion of
    Fibreboard management, necessary for a fair presentation of the results of
    the respective interim periods.  Results of operations for interim periods
    are not necessarily indicative of results to be expected for an entire
    year.

2.  Net earnings per common and common equivalent shares were calculated
    using the weighted average number of common shares outstanding during the
    period plus the net additional number of shares which would be issuable
    upon the exercise of stock options, assuming Fibreboard used the proceeds
    received to purchase additional shares at market value.  Fibreboard will
    adopt Statement of Financial Accounting Standards No. 128, Earnings per
    Share (SFAS 128), effective December 15, 1997.  SFAS 128 requires the
    calculation of basic earnings per share which is computed by dividing net
    income by the weighted average number of shares of common stock outstanding
    during the period and diluted earnings per common share which is computed
    using the weighted average number of shares of common stock and common
    stock equivalents.  As required, Fibreboard will report earnings per share 
    in accordance with SFAS 128. Pro forma basic earnings per share from 
    continuing operations for the three months ended March 31, 1997 and 1996 
    would have been $0.15 and $(0.04). Pro forma diluted earnings per share 
    from continuing operations for the three months ended March 31, 1997 and 
    1996 would have been $0.14 and $(0.04).
    
3.  Inventories are valued at the lower of cost (first in, first out) or
    market.  Inventory costs include material, labor and operating overhead. 
    Operating supplies are priced at average cost.  Inventories were as follows:

4.  The functional currency of Fibreboard's foreign operations is the 
    applicable local currency.  Translation from the applicable foreign
    currency to U. S. dollars is performed for balance sheet accounts using
    exchange rates in effect at the balance sheet date and for sales and
    expense accounts using a weighted average exchange rate during the period. 
    The resulting translation adjustment is reflected as a component of
    stockholder's equity. 
    
    Realized translation losses were $237 and $354 for the three months ended
    March 31, 1997 and 1996.  To mitigate future translation gains or losses on
    U. S. denominated debt held by a Canadian subsidiary, Fibreboard entered
    into a foreign currency swap during 1996 under which Fibreboard will receive
    U.S. $25,000 in exchange for Canadian $34,290 upon contract termination in 
    August 1998. Gains or losses due to currency exchange fluctuations during 
    the contract period are deferred.
    
    The Canadian subsidiary also enters into forward exchange and purchased
    foreign currency option contracts in an effort to mitigate fluctuations 
    in transactions denominated in U.S. dollars.  The gains or losses on
    these contracts are included in income in the period in which the 
    exchange rates change.  No contracts of this type were entered into 
    during 1996, and the gains and losses recorded on such contracts
    during 1997 were not material.

5.  Information about Fibreboard's industry segments is set forth below:

6.  In March 1997, Fibreboard increased its U. S. revolving credit facility
    from $125,000 to $225,000.  At March 31, 1997, $234,400 was available 
    for borrowing under the U. S. and Canadian revolving credit facilities.
    
7.  On January 1, 1997, Fibreboard acquired the Florida-based net assets of
    Gentek Building Products, including ten building product distribution sites
    and two manufacturing plants that fabricate aluminum windows and doors, for
    $11,816 in cash including the assumption of certain liabilities.  The 
    acquisition was accounted for as a purchase.

8.  Prior to 1972, Fibreboard manufactured insulation products containing
    asbestos.  Fibreboard has since been named as a defendant in many thousands
    of personal injury claims for injuries allegedly

    caused by asbestos exposure and in asbestos-in-buildings actions involving 
    many thousands of buildings.

    Fibreboard has unique insurance coverage for personal injury claims. 
    During 1993, Fibreboard and its insurers, Continental Casualty Company
    (Continental) and Pacific Indemnity Company (Pacific), entered into the
    Insurance Settlement Agreement, and Fibreboard, its insurers and plaintiffs
    representatives entered into the Global Settlement Agreement.  These
    agreements are interrelated and require final court approval.  On July 26,
    1996, the U. S. Fifth Circuit Court of Appeals affirmed the Global
    Settlement by a majority decision and the Insurance Settlement by an
    unanimous decision.
    
    A petition for rehearing on the Global Settlement was filed with the Fifth
    Circuit in September 1996 and subsequently rejected by the Court.  The
    parties opposing the Global Settlement have filed petitions seeking review
    with the U. S. Supreme Court.  The Supreme Court will likely rule whether
    to grant these petitions during 1997.  If granted, final resolution of
    the Global Settlement may not be known until 1998 or later.
    
    On October 24, 1996, the statutory time period to seek further review of
    the Insurance Settlement approval judgment lapsed with no petition for
    review having been filed with the U. S. Supreme Court.  Therefore, the
    Insurance Settlement approval judgment is now final and not subject to
    further appeal.
    
    Fibreboard will continue to seek approval of the Global Settlement.  Under
    the Global Settlement, all asbestos-related personal injury liabilities of
    Fibreboard will be resolved through insurance funds and existing corporate
    reserves.  Upon final approval, Fibreboard's insurers are required to pay
    existing settlements and assume full responsibility for any claims filed
    before August 27, 1993, the date the settling parties reached agreement on
    the terms of the Global Settlement.  A court-supervised claims processing
    trust has already been established to administer the $1,535,000 dedicated
    to resolving claims filed against Fibreboard since August 27, 1993, and any
    further claims that might otherwise be asserted in the future.  
    
    Fibreboard will contribute $10,000 plus accrued interest toward the
    settlement trust, which it will obtain from other remaining insurance
    sources and existing reserves.  The Home Insurance Company has already paid
    $9,892 into the escrow account  on behalf of Fibreboard, in satisfaction of
    an earlier settlement agreement.  At December 31, 1996, Fibreboard owed the
    escrow account $224. 
    
    The remainder of the trust will be funded by Continental and Pacific. 
    These insurers have placed $1,525,000 in an interest-bearing escrow account
    pending court approval of the settlements.  The balance of the escrow
    account was $1,697,815 at December 31, 1996, after payment of interim
    expenses associated with the Global Settlement.  A permanent injunction
    barring the filing of any further claims against Fibreboard or its insurers
    is included as part of the Global Settlement.
    
    The Insurance Settlement, which is now final, is structured as an
    alternative solution in the event the Global Settlement fails to receive
    final approval.  Under the Insurance Settlement, Continental and Pacific
    will pay in full settlements reached as of August 27, 1993 and provide
    Fibreboard with up to $2,000,000, plus accrued interest, in additional
    funds as needed to resolve unsettled claims as of August 27, 1993 and
    claims which have been or may be filed against Fibreboard after that date. 
    Under the Insurance Settlement, Fibreboard will continue to manage the
    defense and resolution of asbestos-related personal injury claims.
    
    The Insurance Settlement will not be fully implemented or funded until such
    time as the Global Settlement has been finally resolved.  In the event the
    Global Settlement is finally approved, the

    Insurance Settlement will not be implemented.  If, however, the Global 
    Settlement is not approved, then the Insurance Settlement will be 
    implemented.  However, the insurers began paying deferred settlement 
    obligations in the fourth quarter of 1996.

    Fibreboard believes the amounts available under the Insurance Settlement
    Agreement will be adequate to fund the ongoing defense and indemnity costs
    associated with asbestos-related personal injury claims for the foreseeable
    future.

    The following tables illustrate asbestos-related personal injury claims
    activity for the periods indicated:

          Claims pending at end of period                90,241         49,619

      1  Under Green Card Settlements, there is no determination of liability
         by Fibreboard to a claimant.  Instead, Fibreboard waives the statute
         of limitations should a claimant develop an asbestos-related
         impairment in the future.

      2  Often, multiple claims are filed for the same injury.  In addition,
         Fibreboard's claims database was constructed by merging several 
         third-party databases in 1988.  Fibreboard has attempted to identify
         duplicate claims and remove them from the database.  It is often not
         possible to fully identify duplicate claims until the claims are
         prepared for trial.  Fibreboard anticipates additional future
         adjustments.

      3  The higher settlement average in 1996 and 1997 is due to the absence 
         of group settlements, where large numbers of low value cases are 
         traditionally settled along with more valuable cases, and due to the 
         fact that in 1996 and 1997 a relatively small number of individual 
         cases involving more seriously injured plaintiffs were settled during 
         the pendency of the Global Settlement injunction
      ------------------------------------------------------------------------

    At the end of 1991, Fibreboard attempted to quantify its liability for
    asbestos-related personal injury claims then pending as well as anticipated
    to be received through the end of the decade.  There are many opportunities
    for error in such an exercise.  Assumptions concerning the number of claims
    to be received, the disease mix of pending and future claims and
    projections of defense and indemnity costs may or may not prove correct. 
    Fibreboard's assumptions were based on its historical experience, modified
    as appropriate for anticipated demographic changes or changes in the
    litigation environment.

<PAGE>

                   FIBREBOARD CORPORATION AND SUBSIDIARIES

    Notwithstanding the inherent risk of significant error in such a
    calculation, Fibreboard estimated that the amount necessary to defend and
    dispose of asbestos-related personal injury claims pending at December 31,
    1991, and anticipated through the end of the decade plus the costs of
    prosecuting its insurance coverage litigation would aggregate $1,610,000. 
    Because of the dynamic nature of this litigation, it is more difficult to
    estimate how many personal injury claims will be received after 1999 as
    well as the costs of defending and disposing of those future claims. 
    Consequently, Fibreboard's estimated liability contains no amounts for
    personal injury claims received after the end of the decade, although it is
    likely additional claims will be received thereafter.

    Fibreboard believed it probable that it would ultimately receive insurance
    proceeds of $1,584,000 for the defense and disposition of the claims
    quantified above. As a result, Fibreboard recorded a liability, net of
    anticipated insurance proceeds, of $26,000 at December 31, 1991,
    representing its best estimate of the unreimbursed cost of resolving
    personal injury claims then pending and anticipated through the remainder
    of the decade as well as the costs of prosecuting the insurance coverage
    litigation.  Although there likely will be claims filed beyond the end of
    the decade, these have not been estimated.

    Although Fibreboard, its insurers and plaintiffs' representatives entered
    into the Insurance and Global Settlements discussed above, Fibreboard does
    not believe these settlements impact its estimate of liability through the
    end of the decade.  However, during 1995, Fibreboard recorded a $4,000
    reversal of previously established reserves for anticipated unreimbursable
    costs as a result of a reduction in its estimate of the amounts which will
    be needed for such purpose in the event neither the Global nor Insurance
    Settlements are finally approved.  Fibreboard anticipates reevaluating and
    updating its estimates of liability once it is determined which of the
    Global Settlement or the Insurance Settlement is ultimately implemented.

9.  Subsequent Event

    On May 5, 1997, Fibreboard completed the purchase of the stock of Fabwel,
    Inc. for approximately $120 million, subject to post closing adjustments. 
    Fabwel, headquartered in Elkhart, Indiana, is a major producer and supplier
    of customized exterior components for the manufactured housing,
    recreational vehicle, building and construction and transportation/cargo
    industries.  Fabwel reported net sales of $194.2 million for the year ended
    December 31, 1996, pre-tax income of $11.0 million, earnings before 
    interest and taxes of $13.9 million, and earnings before interest, taxes, 
    depreciation and amortization of $17.0 million. The purchase was
    funded by $100.0 million from Fibreboard's existing revolving credit
    facility and cash on hand.  The acquisition will be accounted for as 
    a purchase.

ITEM 2 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
       RESULTS OF OPERATIONS

       QUARTER ENDED MARCH 31, 1997 VS. 1996

       OVERALL
       -------

       - Net sales increased 45% due to the acquisition of Stone Products
         (acquired July 1996), additional Norandex branches and increased
         shipments of residential building products.

       - Gross margin increased 56%, and increased as a percent of sales from
         28% in 1996 to 30% in 1997.  Lower raw material costs and operating
         efficiencies in the residential building products group resulted in
         improved consolidated gross margin while stable raw material costs
         (relative to sales prices) were experienced for industrial building
         products.
       
       - Selling, general and administrative costs increased 48% due to the
         increase in the number of Norandex branches since the prior year, and
         the acquisition of Stone Products.
       
       - Goodwill amortization increased 49% between years as a result of the
         acquisition of Stone Products.
       
       - As a result of the factors noted above, operating income increased
         $1.6 million between years.
       
       - Interest expense declined 19% as a result of decreased debt balances
         combined with the expiration of an interest rate cap during the 
         fourth quarter of 1996. 
       
       - Interest and other income increased $1.0 million as average cash
         balances were higher, and gains on sales of surplus assets
         totaled $0.6 million in 1997.
       
       - The income tax rate was 41.5% for 1997 and 40% for 1996.
       
       - Income from continuing operations increased $1.6 million as a result
         of the above factors.
       
       - Net income for the first quarter of 1996 included the operating
         results of the resort operations which were sold during the fourth
         quarter of 1996.

       SEGMENT DISCUSSION
       ------------------

       BUILDING PRODUCTS:

         Residential products sales increased 58% due to the acquisition of
         Stone Products, new Norandex branches added during the past year, and
         increased shipment of vinyl products.  Stone Products contributed
         $12.4 and $1.3 million of sales and operating income in 1997.  Had 
         Stone Products been acquired at the beginning of 1996, it would have 
         contributed $9.3 million of pro forma sales for the first quarter 
         of 1996.  Because of the limited nature of pro forma adjustments,
         Fibreboard does not believe pro forma comparisons of operating results
         between periods are indicative of the results that would have occurred
         if the combination had been in effect throughout 1996 or which 
         may be obtained in the future.  Norandex branch same store sales 
         increased 15% between comparable quarters of 1996 and 1997. 
         Shipments of vinyl siding increased  42% from 585,000 squares in
         1996 to 830,000 squares in 1997 as a 

                                       13

                       FIBREBOARD CORPORATION AND SUBSIDIARIES

         result of a 48% increase in shipments by Norandex and a 34% 
         increase in shipments by Vytec. Operating profit increased 665% 
         from $0.3 million in 1996 to $2.4 million.  The improvement in 
         operating profits was due to the acquisitions of Stone Products, 
         increased sales volumes at Norandex and Vytec and higher 
         manufacturing efficiencies during 1997.

    -    Industrial products sales decreased 7% as a result of decreased sales
         of calcium silicate ("CalSil") products.  Operating profits declined
         6% due primarily to the volume declines of CalSil sales. 

    UNALLOCATED EXPENSE:

    -    Unallocated expenses increased 18% or $0.4 million between years.

    FINANCIAL CONDITION


    -    Cash on hand at March 31, 1997 aggregated $23.0 million, which will be
         utilized to fund continuing operations and the acquisition of Fabwel,
         Inc.

    -    Borrowings under Fibreboard's revolving credit facilities aggregated
         $1.0 million at March 31, 1997.  Total availability was $234.4
         million.  In addition, Fibreboard had $25.0 million outstanding in the
         form of a five-year term loan.

    -    Including Fabwel, capital expenditures of between $33 to $38 million 
         are anticipated during 1997.  Major anticipated projects include the
         construction of a vinyl siding manufacturing plant in Joplin, Missouri
         at an approximate total cost of $15.0 million (completed on April 
         14, 1997), $6.0 million to increase production capacity and improve 
         productivity at the vinyl siding manufacturing plants in London, 
         Ontario and Claremont, North Carolina, and approximately $6.0 million 
         for expansion of Stone Products production facilities. For the first 
         three months of 1997, Fibreboard has expended approximately $10.9 
         million on these and other projects.

    -    In addition to cash needs related to continuing operations, Fibreboard
         must fund its minimal on-going asbestos-related costs. To date,
         substantially all such costs, other than the cost of litigating
         insurance coverage issues and certain in-house expenses, have been
         funded from insurance resources.  At March 31, 1997, Fibreboard had
         $4.5 million in cash on hand restricted for asbestos-related costs. 
         Fibreboard believes that substantially all of its cash needs for
         asbestos-related expenditures will be satisfied through existing
         settlements with asbestos-in-buildings insurers or through the
         Insurance Settlement which became final on October 24, 1996.

    -    Additional information regarding the asbestos-related litigation can
         be found in Note 8 to the Consolidated Financial Statements beginning
         on page 10.

(the "ORIGINAL CREDIT AGREEMENT").

     B.   The Revolving Borrower is engaged directly and through its various
Subsidiaries in the Existing Lines of Business (as defined herein).

     C.   The Revolving Borrower and/or its Subsidiaries may from time to time

     D.   Under the Original Credit Agreement, the Revolving Borrower has

<PAGE>
          (d)  The Revolving Borrower has guaranteed such Term Loans.

     E.   The Revolving Borrower and the Term Borrower have requested the
Co-Agents and the Lenders to amend and restate the Original Credit Agreement to

the financial covenants, definitional provisions, standards or other terms or
conditions found in this Agreement, (i) the parties hereto agree to enter into

those covenants, definitional provisions, standards or other terms and
conditions as criteria for evaluating the Revolving Borrower's and its

                   COMMITMENTS, BORROWING PROCEDURES AND NOTES

     SECTION 2.1  COMMITMENTS.  On the terms and subject to the conditions of
this Agreement (including ARTICLE V), each Lender severally agrees as follows:

     SECTION 2.1.1  REVOLVING LOAN COMMITMENTS; TERM LOANS.  Subject to SECTION
2.1.3,

          (a)  From time to time on any Business Day occurring prior to the
     Revolving Commitment Termination Date, each Lender will make Loans
     (relative to such Lender, its "COMMITTED REVOLVING LOANS") to the Revolving
     Borrower equal to such Lender's Percentage of the aggregate amount of the
     Borrowing of Committed Revolving Loans requested by the Revolving Borrower
     to be made on such day up to an aggregate principal amount not exceeding at
     any time outstanding the Revolving Commitment Amount.  On the terms and
     subject to the conditions hereof, the Revolving Borrower may from time to
     time borrow, prepay and reborrow Committed Revolving Loans.

          (b)  The Borrower acknowledges that the aggregate outstanding
     principal amount of the Term Loans on the Restatement Effective Date under
     the Original Credit Agreement is $25,000,000.  On the Restatement Effective
     Date, pursuant to SECTION 5.13, each Lender will purchase or sell
     assignments of such Term Loans such that, immediately following such
     purchases and sales, each Lender's principal amount of Term Loans will be
     equal to such Lender's Percentage of $25,000,000.

     SECTION 2.1.2  COMMITMENT TO ISSUE LETTERS OF CREDIT.  From time to time on
any Business Day, each Issuer will issue, and each Lender will participate in,
the Letters of Credit, in accordance with ARTICLE IV.

     SECTION 2.1.3  LENDERS NOT PERMITTED OR REQUIRED TO MAKE REVOLVING LOANS OR
ISSUE OR PARTICIPATE IN LETTERS OF CREDIT UNDER CERTAIN CIRCUMSTANCES.  No
Lender shall be permitted or required to

          (a) make any Revolving Loan if, after giving effect thereto, the
     aggregate outstanding principal amount

               (i) of all Revolving Loans of all Lenders, together with all
          Letter of Credit Outstandings, would exceed the Revolving Commitment
          Amount, or

                                      -32-
<PAGE>

               (ii) of all Revolving Loans of such Lender (other than any Bid
          Loans or Swingline Loans of such Lender), together with its Percentage
          of all Letter of Credit Outstandings, would exceed such Lender's
          Percentage of the Revolving Commitment Amount; or

          (b) issue (in the case of any Issuer) or participate in (in the case
     of each Lender) any Letter of Credit if, after giving effect thereto

               (i) the aggregate amount of all Letter of Credit Outstandings
          would exceed $30,000,000,

               (ii) all Letter of Credit Outstandings together with the
          aggregate outstanding principal amount of all Revolving Loans of all
          Lenders would exceed the Revolving Commitment Amount, or

               (iii) such Lender's Percentage of all Letter of Credit
          Outstandings together with the aggregate outstanding principal amount
          of all Revolving Loans of such Lender (other than any Bid Loans or
          Swingline Loans of such Lender) would exceed such Lender's Percentage
          of the Revolving Commitment Amount.

     SECTION 2.1.4  EXTENSION OF COMMITMENT TERMINATION DATES AND STATED
MATURITY DATE. (a) Not less than 60 days nor more than 120 days before (i) the
first anniversary of the date of the Restatement Effective Date and/or (ii) the
then current Revolving Commitment Termination Date and Stated Maturity Date for
Term Loans, the Revolving Borrower and the Term Borrower may, by written request
delivered to the Administrative Agent, request that the Revolving Commitment
Termination Date and Stated Maturity Date for Term Loans be extended by all the
Lenders for a period of one year from the then-current Revolving Commitment
Termination Date and Stated Maturity Date for Term Loans.  The Administrative
Agent shall notify the Lenders of any such request.  Such extension shall only
be effective upon approval thereof in writing by the Administrative Agent and
all the Lenders, and the execution and delivery of such amendments to the Loan
Documents and other documents as the Administrative Agent may require in
connection with such extension.  The Administrative Agent and each Lender may
accept or reject any request for an extension in its sole and absolute
discretion.  The Administrative Agent and each Lender shall use reasonable
efforts to accept or reject any such request within 30 days after receiving
notice thereof, PROVIDED that any failure by the Administrative Agent or Lender
to respond to such a request shall be deemed to be a rejection thereof.

     (b)  If any Lender rejects any Borrower's request for an extension
hereunder, subject to SECTION 11.11, such Borrower may: 

                                      -33-

(i) request one or more of the other Lenders to acquire and assume (in such 
Lender's sole discretion) all or part of such rejecting Lender's Loans and 
Commitments; or (ii) designate a replacement bank or financial institution to 
acquire and assume all or part of such rejecting Lender's Loans and 
Commitments.  Any such designation of a replacement bank or financial 
institution under CLAUSE (ii) shall be subject to the prior written consent 
of the Administrative Agent and the other Lenders (which consent shall not be 
unreasonably withheld).

     SECTION 2.2  MANDATORY AND OPTIONAL REDUCTIONS OF REVOLVING COMMITMENT
AMOUNTS.

     SECTION 2.2.1  MANDATORY REDUCTIONS.  At no time shall the Swingline
Commitment exceed the Revolving Commitment Amount, and any reduction of the
Revolving Commitment Amount which reduces the Revolving Commitment Amount below
the then current amount of the Swingline Commitment shall result in an automatic
corresponding reduction of the Swingline Commitment to the amount of the
Revolving Commitment Amount, as so reduced, without any action on the part of
the Swingline Lender.

     SECTION 2.2.2  OPTIONAL REDUCTIONS.  The Revolving Borrower may, from time
to time on any Business Day occurring after the time of the initial Borrowing
hereunder, voluntarily reduce the amount of the Revolving Commitment Amount;
PROVIDED, HOWEVER, that all such reductions shall require at least five Business
Days' irrevocable prior written notice to the Administrative Agent and be
permanent, and any partial reduction of the Revolving Commitment Amount shall be
in a minimum amount of $5,000,000 and in an integral multiple of $1,000,000;
PROVIDED FURTHER, HOWEVER, that no such reduction shall be permitted if, after
giving effect thereto and to any prepayments of the Committed Revolving Loans
made on the effective date thereof, the outstanding principal amount of
Committed Revolving Loans, Swingline Loans and Bid Loans when taken together
with Letter of Credit Outstandings would exceed the Revolving Commitment Amount
then in effect.  Once reduced in accordance with this SECTION 2.2.2, the
reduction in the Revolving Commitment Amount shall be applied to each Lender's
Commitment in accordance with such Lender's Percentage.  All accrued commitment
fees to the effective date of any reduction of Commitments shall be paid on the
effective date of such reduction or termination.

     SECTION 2.3  PROCEDURE FOR COMMITTED BORROWINGS.  By delivering a Borrowing
Request to the Administrative Agent on or before 9:00 a.m., San Francisco time,
on a Business Day, the Revolving Borrower may from time to time irrevocably
request, on not less than one nor more than five Business Days' notice, in the
case of Base Rate Committed Loans, and on not less than three nor more than five
Business Days' notice, in the case of Eurodollar Committed Loans, that a
Committed Borrowing be made in

<PAGE>

a minimum amount of $5,000,000 and an integral multiple of $1,000,000, or in

of such notice, the Agent shall advise each Lender thereof.  On the terms and 
subject to the conditions of this Agreement, each Committed Borrowing shall 
be comprised of the Type of Loans, and shall be made on the Business Day, 
specified in such Borrowing Request.  On or before 11:00 a.m. (San Francisco

Agent same day funds in an amount equal to such Lender's Percentage of the 
requested Committed Borrowing.  Such deposit will be made to an account which

Lenders.  To the extent funds are timely received from the Lenders, the 
Administrative Agent shall make such funds available to the applicable 
Borrower by wire transfer on such Business Day to the accounts such Borrower 
shall have specified in its Borrowing Request.  No Lender's obligation to 
make any Loan shall be affected by any other Lender's failure to make any 
Loan.

Continuation/Conversion Notice to the Administrative Agent on or before 9:00
a.m., San Francisco time, on a Business Day, the Revolving Borrower and/or Term

     Committed Loans or continuation of Eurodollar Committed Loans, and

integral multiple of $1,000,000, of any Committed Loans be, in the case of Base
Rate Committed Loans, converted into Eurodollar Committed Loans or, in the case
of Eurodollar Committed Loans, converted into a Base Rate Committed Loan or
continued as a Eurodollar Committed Loan (in the absence of delivery of a
Continuation/Conversion Notice with respect to any Eurodollar Committed Loan at
least three Business Days before the last day of the then current Interest
Period with respect thereto, such Eurodollar Committed Loan shall, on such last
day, automatically convert to a Base Rate Committed Loan); PROVIDED, HOWEVER,
that (x) each such conversion or continuation shall be pro rated among the
applicable outstanding Committed Loans of all Lenders, and (y) no portion of the
outstanding principal amount of any Loans may be continued as, or be converted
into, Eurodollar Committed Loans when any Default has occurred and is
continuing.

is submitted solely to correct a manifest error in such former Competitive Bid
and only if received within the times set forth in SUBSECTION 2.6(c).  The
Administrative Agent's notice to the Revolving Borrower shall specify (1) the
aggregate principal amount of Bid Loans for which offers have been received for
each Interest Period specified in the related Competitive Bid Request; and (2)
the respective principal amounts and Eurodollar Bid Margins or Absolute Rates,
as the case may be, so offered.  Subject only to the provisions of SECTIONS 5.1,
5.2 and 6.2 

                                      -38-

hereof and the provisions of this SUBSECTION (d), any Competitive Bid shall 
be irrevocable except with the written consent of the Administrative Agent 
given on the written instructions of the Revolving Borrower.

          (e)  Not later than 7:30 a.m. (San Francisco time) three Business Days
prior to the proposed date of Borrowing, in the case of a Eurodollar Auction, or
7:30 a.m. (San Francisco time) on the proposed date of Borrowing, in the case of
an Absolute Rate Auction, the Revolving Borrower shall notify the Administrative
Agent of its acceptance or non-acceptance of the offers so notified to it
pursuant to SUBSECTION 2.6(d).  The Revolving Borrower shall be under no
obligation to accept any offer and may choose to reject all offers.  In the case
of acceptance, such notice shall specify the aggregate principal amount of
offers for each Interest Period that is accepted.  The Revolving Borrower may
accept any Competitive Bid in whole or in part; PROVIDED that:

               (i)  the aggregate principal amount of each Bid Borrowing
     may not exceed the applicable amount set forth in the related
     Competitive Bid Request;

               (ii)  the principal amount of each Bid Borrowing must be
     $5,000,000 or in any multiple of $1,000,000 in excess thereof;

               (iii)  acceptance of offers may only be made on the basis of
     ascending Eurodollar Bid Margins or Absolute Rates within each
     Interest Period, as the case may be; and

               (iv)  the Revolving Borrower may not accept any offer that
     is described in SUBSECTION 2.6(c)(iii) or that otherwise fails to
     comply with the requirements of this Agreement.

          (f)  If offers are made by two or more Lenders with the same
Eurodollar Bid Margins or Absolute Rates, as the case may be, for a greater
aggregate principal amount than the amount in respect of which such offers are
accepted for the related Interest Period, the principal amount of Bid Loans in
respect of which such offers are accepted shall be allocated by the
Administrative Agent among such Lenders as nearly as possible (in such
multiples, not less than $1,000,000, as the Administrative Agent may deem
appropriate) in proportion to the aggregate principal amounts of such offers.
Determination by the Administrative Agent of the amounts of Bid Loans shall be
conclusive in the absence of manifest error.

          (g)  (i)  The Administrative Agent will promptly notify each Lender
     having submitted a Competitive Bid if its offer 

                                      -39-
<PAGE>

     has been accepted and, if its offer has been accepted, of the amount 
     of the Bid Loan or Bid Loans to be made by it on the date of the Bid 
     Borrowing.

               (ii)  Each Lender which has received notice pursuant to
     SUBSECTION 2.6(g)(i) that its Competitive Bid has been accepted, shall
     make the amounts of such Bid Loans available to the Administrative
     Agent for the account of the Revolving Borrower by deposit to an
     account designated by the Administrative Agent, by 11:00 a.m. (San
     Francisco time) on such date of Bid Borrowing, in funds immediately
     available to the Administrative Agent.

               (iii)  Promptly following each Bid Borrowing, the
     Administrative Agent shall notify each Lender of the ranges of bids
     submitted and the highest and lowest Bids accepted for each Interest
     Period requested by the Revolving Borrower and the aggregate amount
     borrowed pursuant to such Bid Borrowing.

               (iv)  From time to time, the Revolving Borrower and the
     Lenders shall furnish such information to the Administrative Agent as
     the Administrative Agent may request relating to the making of Bid
     Loans, including the amounts, interest rates, dates of borrowings and
     maturities thereof, for purposes of the allocation of amounts received
     from the Revolving Borrower for payment of all amounts owing
     hereunder.

          (h)  If, on or prior to the proposed date of Borrowing, the Revolving
Commitment Termination Date shall not have occurred and if, on such proposed
date of Borrowing all applicable conditions to funding referenced in
SECTIONS 5.1, 5.2 and 6.2 hereof are satisfied, the Lenders whose offers the
Revolving Borrower has accepted will fund each Bid Loan so accepted.  Nothing in
this SECTION 2.6 shall be construed as a right of first offer in favor of the
Lenders or to otherwise limit the ability of the Revolving Borrower to request
and accept credit facilities from any Person (including any of the Lenders),
provided that no Default or Event of Default would otherwise arise or exist as a
result of the Revolving Borrower executing, delivering or performing under such
credit facilities.

     SECTION 2.7    SWINGLINE LOANS.

     (a)  Subject to the terms and conditions hereof, the Swingline Lender
severally agrees to make a portion of the Revolving Commitment Amount available
to the Revolving Borrower by making swingline loans (individually, a "SWINGLINE
LOAN"; collectively, the "SWINGLINE LOANS") to the Revolving Borrower on any
Business Day prior to the Revolving Commitment Termination 

                                      -40-
<PAGE>

Date in accordance with the procedures set forth in this Section in an 
aggregate principal amount at any one time outstanding not to exceed 
$20,000,000, notwithstanding the fact that such Swingline Loans, when 
aggregated with the Swingline Lender's outstanding Committed Loans, may 
exceed the Swingline Lender's Commitment (the amount of such commitment of 
the Swingline Lender to make Swingline Loans to the Revolving Borrower 
pursuant to this SUBSECTION 2.7(a), as the same shall be reduced pursuant to 
SUBSECTION 2.2.1) or as a result of any assignment pursuant to SECTION 
11.11.1, the Swingline Lender's "SWINGLINE COMMITMENT"); PROVIDED, that at no 
time shall (i) the sum of the outstanding principal amount of all Swingline 
Loans PLUS the outstanding principal amount of all Committed Loans and Bid 
Loans PLUS the Letter of Credit Outstandings exceed the Revolving Commitment 
Amount, or (ii) the outstanding principal amount of all Swingline Loans 
exceed the Swingline Commitment.  Additionally, no more than four Swingline 
Loans may be outstanding at any one time, and except as otherwise provided in 
SECTION 3.2.2, all Swingline Loans shall at all times bear interest at a rate 
per annum equal to the Alternate Base Rate unless otherwise agreed to by the 
Swingline Lender in its sole discretion.  Within the foregoing limits, and 
subject to the other terms and conditions hereof, the Revolving Borrower may 
borrow under this SUBSECTION 2.7(a), repay pursuant to SECTION 3.1 and 
reborrow pursuant to this SUBSECTION 2.7(a).

          (b)  The Revolving Borrower shall provide the Administrative Agent
(with a copy to the Swingline Lender) with irrevocable written notice (including
notice via telephone call confirmed immediately by facsimile) in the form of a
Borrowing Request of any Swingline Loan requested hereunder (which notice must
be received by the Swingline Lender and the Administrative Agent prior to 12:00
noon (San Francisco time) on the requested Borrowing date) specifying (i) the
amount to be borrowed, and (ii) the requested Borrowing date, which must be a
Business Day.

          Upon receipt of the Borrowing Request, the Swingline Lender will
immediately confirm with the Administrative Agent (by telephone or in writing)
that the Administrative Agent has received a copy of the Borrowing Request from
the Revolving Borrower, and, if not, the Swingline Lender will provide the
Administrative Agent with a copy thereof.  Unless the Swingline Lender has
received notice prior to 2:00 p.m. on such Borrowing date from the
Administrative Agent (A) directing the Swingline Lender not to make the
requested Swingline Loan as a result of the limitations set forth in the PROVISO
set forth in the first sentence of SUBSECTION 2.7(a); or (B) that one or more
conditions specified in ARTICLE VI are not then satisfied; then, subject to the
terms and conditions hereof, the Swingline Lender will, not later than 3:00 p.m.
(San Francisco time) on the Borrowing date specified in such Borrowing Request,
make the amount of its Swingline Loan available to the Administrative Agent for
the 

                                      -41-
<PAGE>

account of the Revolving Borrower at an account designated by the 
Administrative Agent in funds immediately available to the Administrative 
Agent. The proceeds of such Swingline Loan will then promptly be made 
available to the Revolving Borrower by the Administrative Agent crediting the 
account of the Revolving Borrower on the books of BofA with the aggregate of 
the amounts made available to the Administrative Agent by the Swingline 
Lender and in like funds as received by the Administrative Agent.  Each 
Borrowing pursuant to this Section shall be in an aggregate principal amount 
equal to two hundred fifty thousand dollars ($250,000) or an integral 
multiple of one hundred thousand dollars ($100,000) in excess thereof, unless 
otherwise agreed by the Swingline Lender.

          (c)  If (i) any Swingline Loans shall remain outstanding at 9:00 a.m.
(San Francisco time) on the Business Day immediately prior to a Swingline
Clean-Up Day and by such time on such Business Day the Administrative Agent
shall have received neither

                    (A) a Borrowing Request delivered pursuant to SECTION 2.3
               requesting that Committed Revolving Loans be made pursuant to
               SECTION 2.1 or Bid Loans be made pursuant to SECTION 2.5 on the
               Swingline Clean-Up Day in an amount at least equal to the
               aggregate principal amount of such Swingline Loans, nor

                    (B) any other notice indicating the Revolving Borrower's
               intent to repay such Swingline Loans with funds obtained from
               other sources, or

          (ii) any Swingline Loans shall remain outstanding during the existence
     of a Default or Event of Default and the Swingline Lender shall in its sole
     discretion notify the Administrative Agent that the Swingline Lender
     desires that such Swingline Loans be converted into Committed Revolving
     Loans,

then the Administrative Agent shall be deemed to have received a Borrowing
Request from the Revolving Borrower pursuant to SECTION 2.3 requesting that Base
Rate Committed Revolving Loans be made pursuant to SECTION 2.1 on such Swingline
Clean-Up Day (in the case of the circumstances described in CLAUSE (i) above) or
on the first Business Day subsequent to the date of such notice from the
Swingline Lender (in the case of the circumstances described in CLAUSE (ii)
above) in an amount equal to the aggregate amount of such Swingline Loans, and
the procedures set forth in SUBSECTIONS 2.3 shall be followed in making such
Base Rate Committed Loans; PROVIDED that such Base Rate Committed Revolving
Loans shall be made notwithstanding the Revolving Borrower's failure to comply
with SECTION 6.2.1; and PROVIDED, FURTHER, that 

                                      -42-
<PAGE>

if a Borrowing of Committed Revolving Loans becomes legally impracticable and 
if so required by the Swingline Lender at the time such Committed Revolving 
Loans are required to be made by the Lenders in accordance with this 
SUBSECTION 2.7(c), each Lender agrees that in lieu of making Committed 
Revolving Loans as described in this SUBSECTION 2.7(c), such Lender shall 
purchase a participation from the Swingline Lender in the applicable 
Swingline Loans in an amount equal to such Lender's Percentage of such 
Swingline Loans, and the procedures set forth in SECTION 2.3 shall be 
followed in connection with the purchases of such participations.  Upon such 
purchases of participations, the prepayment requirements of SUBSECTION 3.1(d) 
shall be deemed waived with respect to such Swingline Loans.  The proceeds of 
such Base Rate Committed Revolving Loans, or participations purchased, shall 
be applied to repay such Swingline Loans.  A copy of each notice given by the 
Administrative Agent to the Lenders pursuant to this SUBSECTION 2.7(c) with 
respect to the making of Committed Revolving Loans, or the purchases of 
participations, shall be promptly delivered by the Administrative Agent to 
the Revolving Borrower.  Each Lender's obligation in accordance with this 
Agreement to make the Committed Revolving Loans, or purchase the 
participations, as contemplated by this SUBSECTION 2.7(c), shall be absolute 
and unconditional and shall not be affected by any circumstance, including 
(1) any set-off, counterclaim, recoupment, defense or other right which such 
Lender may have against the Swingline Lender, the Revolving Borrower or any 
other Person for any reason whatsoever; (2) the occurrence or continuance of 
a Default, an Event of Default or a Material Adverse Effect; or (3) any other 
circumstance, happening or event whatsoever, whether or not similar to any of 
the foregoing.

     SECTION 2.8  FUNDING.  Each Lender may, if it so elects, fulfill its
obligation to make Bid Loans or Swingline Loans based on the Eurodollar Rate or
to make, continue or convert Eurodollar Committed Loans hereunder by causing one
of its foreign branches or Affiliates (or an international banking facility
created by such Lender) to make or maintain such Bid Loan, Swingline Loan or
Eurodollar Committed Loan; PROVIDED, HOWEVER, that such Loan shall nonetheless
be deemed to have been made and to be held by such Lender, and the obligation of
the applicable Borrower to repay such Loan shall nevertheless be to such Lender
for the account of such foreign branch, Affiliate or international banking
facility.  In addition, each Borrower hereby consents and agrees that, for
purposes of any determination to be made for purposes of SECTION 5.1, 5.2, 5.3,
5.4 or 5.11, it shall be conclusively assumed that each Lender elected to fund
all Bid Loans and Swingline Loans based on the Eurodollar Rate and all
Eurodollar Committed Loans by purchasing Dollar deposits in its Eurodollar
Office's interbank eurodollar market.

                                      -43-

     SECTION 2.9  NOTES. (a) The Loans made by each Lender shall be evidenced by
one or more loan accounts or records maintained by such Lender in the ordinary
course of business.  The loan accounts or records maintained by the
Administrative Agent and each Lender shall be conclusive absent manifest error
of the amount of the Loans made by the Lenders to each Borrower and the interest
and payments thereon.  Any failure so to record or any error in doing so shall
not, however, limit or otherwise affect the obligation of such Borrower
hereunder to pay any amount owing with respect to the Loans.

     (b) Upon the request of any Lender made through the Administrative Agent,
the Committed Loans made by such Bank may be evidenced by one or more Committed
Loan Notes and the Bid Loans made by such Lender may be evidenced by one or more
applicable notes ("BID LOAN NOTES"), instead of or in addition to loan accounts.
Each such Lender shall endorse on the schedules annexed to its Note(s) the date,
amount and maturity of each Loan made by it and the amount of each payment of
principal made by the applicable Borrower with respect thereto.  Each such
Lender is irrevocably authorized by the applicable Borrower to endorse its
Note(s) and each Lender's record shall be conclusive absent manifest error;
PROVIDED, HOWEVER, that the failure of a Lender to make, or an error in making,
a notation thereon with respect to any Loan shall not limit or otherwise affect
the obligations of the applicable Borrower hereunder or under any such Note to
such Lender.


                                   ARTICLE III

                   REPAYMENTS, PREPAYMENTS, INTEREST AND FEES

     SECTION 3.1  REPAYMENTS AND PREPAYMENTS.  Each Borrower shall repay in full
the unpaid principal amount of each Loan made to it upon the Stated Maturity
Date therefor.  Prior thereto

          (a) each Borrower may, from time to time on any Business Day, make a
     voluntary prepayment, in whole or in part, of the outstanding principal
     amount of any Loans; PROVIDED, HOWEVER, that

               (i) any such prepayment of a Loan (other than a Bid Loan or a
          Swingline Loan) shall be made PRO RATA among Loans of the same Type
          and, if applicable, having the same Interest Period of all Lenders;

               (ii) any such prepayment of any Loan (other than a Base Rate
          Committed Loan or a Swingline Loan based on the Alternate Base Rate)
          made on any day other than the last day of the Interest Period for
          such Loan shall be subject to such Borrower's obligation to make
          payment, 

                                      -44-
<PAGE>

          if requested by any Lender, of an additional amount equal to
          the amount due under SECTION 5.4 incurred as a result of such
          prepayment being so made at such time;

               (iii) all such prepayments shall require at least three but no
          more than five Business Days' prior written notice (except in the case
          of Base Rate Committed Loans and Swingline Loans based upon the
          Alternate Base Rate which shall require one Business Day's prior
          written notice) to the Administrative Agent and such notice of
          prepayment shall be irrevocable and shall specify (i) the date and
          amount of such prepayment, and (ii) whether such payment is of Base
          Rate Committed Loans, Eurodollar Committed Loans or Swingline Loans,
          or any combination thereof;

               (iv) all such prepayments (A) in the case of Loans other than
          Swingline Loans, shall be in an aggregate minimum amount of $5,000,000
          (or if less, the aggregate outstanding amount of all Loans) and an
          integral multiple of $1,000,000, and (B) in the case of Swingline
          Loans, shall be in an aggregate minimum amount of $250,000 (or if
          less, the aggregate outstanding amount of such Swingline Loan) and an
          integral multiple of $100,000; and

               (v) notwithstanding the terms of SECTION 5.4(a), Bid Loans may
          not be voluntarily prepaid.

          (b) the Revolving Borrower shall, on each date when any reduction in
     the Revolving Commitment Amount shall become effective, including pursuant
     to SECTION 2.2, make a mandatory prepayment (which shall be applied (or
     held for application and bear interest at the rate applicable under SECTION
     4.7) as the case may be, by the Lenders first to the payment of the
     aggregate unpaid principal amount of those Revolving Loans then
     outstanding, and then to the payment of the then outstanding Letter of
     Credit Outstandings) equal to the excess, if any, of the aggregate,
     outstanding principal amount of all Revolving Loans and Letter of Credit
     Outstandings over the Revolving Commitment Amount as so reduced;

          (c) each Borrower shall, immediately upon any acceleration of the
     Stated Maturity Date of any Revolving Loans or Term Loans pursuant to
     SECTION 9.2 or SECTION 9.3, repay all such Loans, unless, pursuant to
     SECTION 9.3, only a portion of all such Loans is so accelerated;

          (d) the Revolving Borrower shall make a mandatory prepayment of
     Swingline Loans (A) if following any reduction of the Swingline Commitment
     pursuant to SUBSECTION 2.2.1 the 

                                      -45-
<PAGE>

     aggregate outstanding principal amount of Swingline Loans would exceed 
     the Swingline Commitment as reduced, on the reduction date in an amount 
     equal to the excess of the Swingline Loans over the Swingline 
     Commitment, and (B) so that for at least one Business Day during each 
     successive two calendar week period the aggregate principal amount of 
     Swingline Loans shall be $0 (a "SWINGLINE CLEAN-UP DAY"), the Revolving 
     Borrower shall prepay on the Swingline Clean-Up Day the outstanding 
     principal amount of the Swingline Loans (which Swingline Loans may not 
     be reborrowed until such Swingline Clean-Up Day has ended); and
     
          (e)  shall repay each Bid Loan on the last day of the relevant
     Interest Period.
     
Each prepayment of any Loans made pursuant to this Section shall be without
premium or penalty, except as may be required by SECTION 5.4.  No voluntary
prepayment of principal of any Revolving Loans shall cause a reduction in the
Revolving Commitment Amount.

     SECTION 3.2  INTEREST PROVISIONS.  Interest on the outstanding principal
amount of Loans shall accrue and be payable in accordance with this SECTION 3.2.


     SECTION 3.2.1  RATES.  Bid Loans shall accrue interest at the applicable
Eurodollar Rate PLUS the Eurodollar Bid Margin, in the case of a Eurodollar Bid
Loan, and at the Absolute Rate, in the case of any Absolute Rate Bid Loan, in
each case as determined in accordance with SECTION 2.6.  Each Swingline Loan
shall bear interest on the principal amount thereof from the date when made
until such Loan becomes due at a rate PER ANNUM equal to the Alternate Base Rate
or such other rate agreed to by the Swingline Lender in its sole discretion.
Pursuant to an appropriately delivered Borrowing Request or
Continuation/Conversion Notice, each Borrower may elect that its Committed Loans
comprising a Borrowing accrue interest at a rate per annum:

          (a) on that portion maintained from time to time as a Base Rate
     Committed Loan, equal to the Alternate Base Rate from time to time in
     effect; and

          (b) on that portion maintained as a Eurodollar Committed Loan, during
     each Interest Period applicable thereto, equal to the sum of the Eurodollar
     Rate (Reserve Adjusted) for such Interest Period plus a margin equal to the
     Applicable Margin in effect on the date such Eurodollar Committed Loan is
     made.

The applicable margin to be added to each Eurodollar Committed Loan (the
"APPLICABLE MARGIN") will be determined by the 

                                      -46-

<PAGE>

Administrative Agent from time to time in accordance with the table set forth 
below based on the Compliance Certificate delivered by the Revolving Borrower 
for the calendar quarter immediately preceding such time (the "PRECEDING 
QUARTER") under CLAUSE (c) of SECTION 8.1.1.  Such determination shall be 
based on the calculation of the Consolidated Funded Debt to Cash Flow Ratio 
set forth in the Compliance Certificate for the Preceding Quarter and shall 
apply from and including the Business Day such Compliance Certificate is 
delivered until but excluding the Business Day the Compliance Certificate is 
delivered for the calendar quarter immediately following the Preceding 
Quarter; PROVIDED that the Applicable Margin for any day after the 
forty-fifth day of any calendar quarter during which the Revolving Borrower 
shall not deliver a Compliance Certificate shall be 1.0% PER ANNUM effective 
until the day such certificate is delivered.  The Applicable Margin for the 
period from the Restatement Effective Date until but excluding the Business 
Day the first Compliance Certificate is delivered hereunder shall be based 
upon the Compliance Certificate most recently delivered under the Original 
Credit Agreement prior to the Restatement Effective Date.  The ratios set 
forth in the table below are for the purpose of interest calculation only and 
shall not affect the Revolving Borrower's obligation to comply with SECTION 
8.2.4.

            Ratio                      Applicable Margin
            -----                      -----------------
     Less than 1.00:1                        0.35%

     The "EURODOLLAR RATE (RESERVE ADJUSTED)" means, relative to any Loan to be
made, continued or maintained as, or converted into, a Eurodollar Committed Loan
for any Interest Period, a rate per annum (rounded upwards, if necessary, to the
nearest 1/16 of 1%) determined pursuant to the following formula:

  Eurodollar Rate       =              EURODOLLAR RATE
  (Reserve Adjusted)        ------------------------------------
                            1.00 - Eurodollar Reserve Percentage

The Eurodollar Rate (Reserve Adjusted) for any Interest Period for Eurodollar
Committed Loans will be determined by the Administrative Agent on the basis of
the Eurodollar Reserve Percentage in effect on, and the applicable rates
furnished to 

                                      -47-
<PAGE>

and received by the Administrative Agent from its Eurodollar office, two 
Business Days before the first day of such Interest Period.

     "EURODOLLAR RATE"  means the rate of interest PER ANNUM determined by the
Administrative Agent as the rate at which dollar deposits in the approximate
amount of any Loan to bear interest at a rate based upon the Eurodollar Rate or
BofA's Eurodollar Committed Loan, as applicable, for such Interest Period would
be offered by BofA's Grand Cayman Branch, Grand Cayman B.W.I. (or such other
office as may be designated for such purpose by BofA), to major banks in the
offshore dollar interbank market at their request at approximately 11:00 a.m.
(New York City time) two Business Days prior to the commencement of such
Interest Period.

     "EURODOLLAR RESERVE PERCENTAGE" means, relative to any Interest Period for
Eurodollar Committed Loans, the reserve percentage (expressed as a decimal and
rounded upward to the nearest 1/100th of 1%) equal to the maximum aggregate
reserve requirements (including all basic, emergency, supplemental, marginal and
other reserves and taking into account any transitional adjustments or other
scheduled changes in reserve requirements) specified under regulations issued
from time to time by the F.R.S. Board and then applicable to assets or
liabilities consisting of and including "Eurocurrency Liabilities", as currently
defined in Regulation D of the F.R.S. Board, having a term approximately equal
or comparable to such Interest Period.

     All Eurodollar Committed Loans shall bear interest from and including the
first day of the applicable Interest Period to (but not including) the last day
of such Interest Period at the interest rate determined as applicable to such
Eurodollar Committed Loan.

     The foregoing adjustment of the Eurodollar Rate on the basis of the
Eurodollar Reserve Percentage in order to determine the Eurodollar Rate (Reserve
Adjusted) shall be made by the Administrative Agent upon notice from time to
time by a Lender that it has become subject to reserves under applicable F.R.S.
Board regulations in respect of "Eurocurrency Liabilities" and that it shall
require compensation for costs it has incurred during an Interest Period as a
consequence of maintaining such reserves during such Interest Period.  Such
compensation shall be limited to the actual costs of such reserves determined by
such Lender to be allocable to its Eurodollar Committed Loan or Loans.  Any
determination by a Lender of the amount of such reserves shall, in the absence
of manifest error, be final, conclusive and binding on all of the parties
hereto.

     SECTION 3.2.2  POST-DEFAULT RATE.  At any time when any Event of Default
shall occur and be continuing, upon the request of the Administrative Agent, at
the direction of the Majority Lenders, each Borrower shall pay, but only to the
extent permitted by law, interest (after as well as before judgment) on its
Loans and all other amounts due from it hereunder at the following rates: (i)
with respect to any amount payable on or in connection with a Base Rate
Committed Loan or Swingline Loan, from the date of such Event of Default until
such amount is paid in full, at a rate PER ANNUM equal to the sum of the
Alternate Base Rate in effect from time to time (but not less than the Alternate
Base Rate in effect at such date), or, in the case of any Swingline Loan, such
other rate at which such Loan bears interest, PLUS 2.0% PER ANNUM (the
"POST-DEFAULT RATE"),(ii) with respect to any amount payable on or in connection
with a Eurodollar Committed Loan or a Bid Loan, from the date of such Event of
Default until the end of the Interest Period for such Loan, at a rate PER ANNUM
equal to the sum of the applicable Eurodollar Rate (Reserve Adjusted), in the
case of a Eurodollar Committed Loan or the applicable Absolute Rate or
Eurodollar Rate PLUS the applicable Eurodollar Bid Margin in the case of any
Eurodollar Bid Loan PLUS, in each such case, 3.0% PER ANNUM, and, thereafter, at

     whole or in part, of principal outstanding on such Loan;

          (c) with respect to Base Rate Committed Loans, and Bid Loans that
     accrue interest at the Absolute Rate, on each Quarterly Payment Date
     occurring after the date of the initial Borrowing hereunder;

          (d) with respect to Eurodollar Committed Loans, or any Bid Loan or
     Swingline Loan that accrues interest at a rate based upon the Eurodollar

     Interest Period shall exceed three months, on the date which would have
     been the last day in an Interest Period of three months);

          (e) with respect to any Base Rate Committed Loans converted into
     Eurodollar Committed Loans on a day when interest would not otherwise have
     been payable pursuant to CLAUSE (c), on the date of such conversion; and

                                      -49-
<PAGE>

          (f) on that portion of any Loans the Stated Maturity Date of which is
     accelerated pursuant to SECTION 9.2 or SECTION 9.3, immediately upon such

     SECTION 3.2.4  INTEREST RATE (CANADA).

     SECTION 3.3  FEES.  Each Borrower agrees to pay the fees set forth in this
SECTION 3.3.  All such fees shall be non-refundable.

     SECTION 3.3.1  COMMITMENT FEES.

     (a) The Revolving Borrower agrees to pay to the Administrative Agent for
the account of each Lender, for the period (including any portion thereof when
any of its Commitments are suspended by reason of the Revolving Borrower's
inability to satisfy any condition of ARTICLE VI) commencing on the Original
Effective Date and continuing through the final Revolving Commitment Termination
Date, a commitment fee on such Lender's Percentage of the sum of the average
daily unused portion of the Revolving Commitment Amount (as in effect from time
to time since the Original Effective Date) calculated at the rates PER ANNUM
determined from time to time for the Current Fiscal Quarter in accordance with
the table set forth below in CLAUSE (c) and the Compliance Certificate delivered
by the Revolving Borrower pursuant to CLAUSE (c) of SECTION 8.1.1.  The amount
of any outstanding Bid Loans and Swingline Loans shall be disregarded for
purposes of calculating any Lender's Percentage of the average daily unused
portion of the Revolving Commitment Amount in accordance with the preceding
sentence except that, in determining such Percentage of the average daily unused
portion for any such Lender for any day, the outstanding principal amount of any
Bid Loans of such Lender on such day shall be subtracted from its Percentage of
the unused portion of the Revolving Commitment Amount in effect on such day.

     (b) The determination of the commitment fee shall be based on the
calculation of the Consolidated Funded Debt to Cash Flow Ratio set forth in the
Compliance Certificate for the Preceding 

                                      -50-

latest Consolidated Funded Debt to Cash Flow Ratio determined under the 
Original Credit Agreement.  Subject to the terms of SECTION 2.2.2 hereof, 
such commitment fees shall be payable by the Revolving Borrower in arrears on 
each Quarterly Payment Date, commencing on June 30, 1997, and on the 
Commitment Termination Date and shall be determined on the basis of a 360 day 
year.

     The Commitment Fee rate applicable for any day after the forty-fifth day of
any quarter of any calendar year during which the Revolving Borrower does not
deliver a Compliance Certificate, effective until the day such certificate is
delivered, shall be the highest rate set forth above.

     SECTION 3.3.2  PARTICIPATION FEES.  On the Restatement Effective Date, the

Revolving Borrower, the Co-Agent, BancAmerica Securities, Inc. and 
Nationsbank Capital Markets, Inc.

     SECTION 3.3.5  LETTER OF CREDIT FACE AMOUNT FEE.  The Revolving Borrower
shall pay to the Administrative Agent for the benefit of the Lenders letter of
credit fees per annum based on the average daily maximum amount available to be
drawn on the outstanding Letters of Credit, payable quarterly in arrears on each
Quarterly Payment Date, commencing on June 30, 1997, and determined on the basis
of a 360 day year.  The applicable fees will be determined by the Administrative
Agent from time to time for the Current Quarter in accordance with the table set
forth below based on the Compliance Certificate delivered by the Revolving
Borrower for the Preceding Quarter under CLAUSE (c) of SECTION 8.1.1.  Such
determination shall be based on the calculations of the Consolidated Funded Debt
to Cash Flow Ratio set forth in the Compliance Certificate for the Preceding
Quarter and shall apply from and including the Business Day such Compliance
Certificate is delivered until but excluding the Business Day the Compliance
Certificate for the calendar quarter immediately following the Preceding Quarter
is delivered.  The Consolidated Funded Debt to Cash Flow Ratio for the period
from the Restatement Effective Date to but excluding the Business Day the first
Compliance Certificate is delivered hereunder shall be the latest Consolidated
Funded Debt to Cash Flow Ratio determined under the Original Credit Agreement.
The ratios set forth in the table below are for the purpose of letter of credit
fee calculation only and shall not affect the Revolving Borrower's obligations
to comply with SECTION 8.2.4.

        2.50:1 or greater                  0.875%

the request of the Administrative Agent, at the direction of the Majority
Lenders, for any day during which an Event of Default shall occur and be
continuing shall be 2.0% PER ANNUM, and (ii) for every day after the forty-fifth

     SECTION 3.3.6  LETTER OF CREDIT ISSUING FEE.  The Revolving Borrower agrees
to pay to the Administrative Agent, for the account of the applicable Issuer, an
issuing fee for each Letter of Credit for the period from and including the date
of issuance of such Letter of Credit to (but not including) the date upon which
such Letter of Credit expires, of 0.125% PER ANNUM of the face amount of such
Letter of Credit and the Revolving Borrower further agrees to pay to the
Administrative Agent, for the account of the applicable Issuer, such Issuer's
customary administrative and processing fees and out-of-pocket expenses relating
to such Letter of Credit.  Such issuing fee shall be determined on the basis of
a 360 day year, and together with other amounts shall be payable by the
Revolving Borrower in arrears on each Quarterly Payment Date, commencing on June
30, 1997, and on the Commitment Termination Date for any period then ending for

                                   ARTICLE IV

                                LETTERS OF CREDIT

     SECTION 4.1  ISSUANCE REQUESTS.  By delivering to the Administrative Agent
and the applicable Issuer an Issuance Request on or before 10:00 a.m. San
Francisco time, the Revolving Borrower may request, from time to time prior to
the Commitment Termination Date and on not less than three nor more than fifteen
Business Days' notice, that such Issuer issue an irrevocable standby letter of
credit (each a "LETTER OF CREDIT"), in support of financial obligations of any
Borrower or its Subsidiaries incurred in such Borrower's or such Subsidiary's
ordinary course of business or in connection with an Approved Acquisition and
which are described in such Issuance Request.  Upon receipt of an Issuance
Request, the Administrative Agent shall promptly notify the Lenders thereof.
Each Letter of Credit shall by its terms:

          (a) be issued in a Stated Amount which

               (i) is at least $100,000; and

               (ii) does not exceed (or would not exceed) the then Letter of
          Credit Availability; and

          (b) be stated to expire on a date (its "STATED EXPIRY DATE") no later
     than fifteen days prior to the then Revolving Commitment Termination Date.

                                      -53-
<PAGE>

So long as no Default has occurred and is continuing, by delivery to the
applicable Issuer and the Administrative Agent of an Issuance Request at least
five but not more than fifteen Business Days prior to the earlier of (i) the
Stated Expiry Date of any Letter of Credit and (ii) (if such Letter of Credit
contains provisions for automatic extension or renewal unless the Issuer advises
the beneficiary thereof that such Letter of Credit will not be extended or
renewed) the date upon which in accordance with the terms of such Letter of
Credit, the Issuer must provide notice to the Revolving Borrower that such
Letter of Credit will expire without renewal on the Stated Expiry Date, the
Revolving Borrower may request such Issuer to extend the Stated Expiry Date of
such Letter of Credit to a date no later than fifteen days prior to the then
Revolving Commitment Termination Date.  Notwithstanding any provision contained
in the foregoing to the contrary, the Revolving Borrower may not request the
issuance of, and no Issuer shall have an obligation to issue, any Letter of
Credit at any time when, or if after giving effect to such issuance, and so long
as, the Letter of Credit Outstandings shall equal or exceed $30,000,000.

     SECTION 4.2  ISSUANCES AND EXTENSIONS.

     (a)  On the terms and subject to the conditions of this Agreement
(including ARTICLE VI), the Issuer shall issue Letters of Credit, and extend the
Stated Expiry Dates of outstanding Letters of Credit, in accordance with the
Issuance Requests made therefor.  Each Issuer will make available the original
of each Letter of Credit which it issues in accordance with the Issuance Request
therefor to the beneficiary thereof (and will promptly provide the Revolving
Borrower and each of the Lenders with a copy of such Letter of Credit) and will
notify the beneficiary under any Letter of Credit of any extension of the Stated
Expiry Date or other renewal thereof.

     (b)  No Issuer is under any obligation to issue any Letter of Credit if:

          (i)  any order, judgment or decree of any Governmental Authority or
     arbitrator shall by its terms purport to enjoin or restrain the Issuer from
     issuing such Letter of Credit, or any Applicable Law with respect to the
     Issuer or any request or directive (whether or not having the force of law)
     from any Governmental Authority with jurisdiction over the Issuer shall by
     its terms purport to direct the Issuer to refrain from the issuance of
     letters of credit generally or such Letter of Credit in particular or shall
     impose upon the Issuer with respect to such Letter of Credit any
     restriction, reserve or capital requirement (for which the Issuer is not
     otherwise compensated hereunder) not in effect on the Restatement Effective
     Date, or shall impose upon the Issuer any unreimbursed loss, cost or
     expense which was not 

                                      -54-
<PAGE>

     applicable on the Original Effective Date and which the Issuer in good 
     faith deems material to it (unless the Revolving Borrower elects to pay 
     such losses, costs and expenses);

          (ii) the Issuer has received written notice from any Lender, the
     Administrative Agent or the Revolving Borrower, on or prior to the Business
     Day prior to the requested date of issuance of such Letter of Credit, that
     one or more of the applicable conditions contained in ARTICLE VI is not
     then satisfied;

          (iii) the expiry date of any requested Letter of Credit is prior to
     the maturity date of any financial obligation to be supported by the
     requested Letter of Credit;

          (iv) any requested Letter of Credit is not in form and substance
     acceptable to the Issuer, or the issuance of a Letter of Credit shall
     violate any applicable policies of the Issuer; or

          (v) any standby Letter of Credit is for the purpose of supporting the
     issuance of any letter of credit by any other Person.

     (c)  SCHEDULE IV hereto sets forth each irrevocable standby letter of
credit issued pursuant to the Original Credit Agreement and outstanding on the
date hereof.  Each such irrevocable standby letter of credit listed on SCHEDULE
IV hereto shall, as of the Restatement Effective Date and thereafter, be a
Letter of Credit for all purposes hereunder.

     SECTION 4.3  EXPENSES.  The Revolving Borrower agrees to pay to the
Administrative Agent for the account of the applicable Issuer(s) all
administrative expenses of such Issuer(s) in connection with the issuance,
maintenance, modification (if any) and administration of each Letter of Credit
issued by such Issuer(s) upon demand from time to time.

     SECTION 4.4  OTHER LENDERS' PARTICIPATION.

     (a) Each Letter of Credit issued pursuant to SECTION 4.2 shall, effective
upon its issuance and without further action, be issued on behalf of all Lenders
(including the Issuer thereof) PRO RATA according to their respective
Percentages.  Each Lender shall, to the extent of its Percentage, be deemed
irrevocably to have participated in the issuance of such Letter of Credit
(including, without limitation, Letters of Credit issued prior to the
Restatement Effective Date) and shall be responsible to reimburse promptly the
Issuer thereof for Reimbursement Obligations which have not been reimbursed by
the Revolving Borrower in accordance with SECTION 4.5, or which have been
reimbursed by the Revolving 

                                      -55-
<PAGE>

Borrower but must be returned, restored or disgorged by such Issuer for any 
reason, and each Lender shall, to the extent of its Percentage, be entitled 
to receive from the Administrative Agent a ratable portion of the letter of 
credit fees received by the Administrative Agent pursuant to SECTION 3.3.4, 
with respect to each Letter of Credit and which accrue on or after the 
Restatement Effective Date.

     (b) In the event that the Revolving Borrower shall fail to reimburse any
Issuer, or if for any reason Loans shall not be made to fund any Reimbursement
Obligation, all as provided in SECTION 4.5 and in an amount equal to the amount
of any drawing honored by such Issuer under a Letter of Credit issued by it, or
in the event such Issuer must for any reason return or disgorge such
reimbursement, such Issuer shall promptly notify each Lender of the unreimbursed
amount of such drawing and of such Lender's respective participation therein.
Each Lender shall make available to such Issuer, whether or not any Default
shall have occurred and be continuing, an amount equal to its respective
participation in same day or immediately available funds at the office of such
Issuer specified in such notice not later than 9:00 a.m., San Francisco time, on
the Business Day (under the laws of the jurisdiction of such Issuer) after the
date notified by such Issuer.

     (c) In the event that any Lender fails to make available to any Issuer the
amount of such Lender's participation in any Letter of Credit as provided
herein, such Issuer shall be entitled to recover such amount on demand from such
Lender together with interest at the daily average Federal Funds Rate for three
Business Days (together with such other compensatory amounts as may be required
to be paid by such Lender to the Administrative Agent pursuant to the Rules for
Interbank Compensation of the council on International Banking or the
Clearinghouse Compensation Committee, as the case may be, as in effect from time
to time) and thereafter at the Alternate Base Rate.

     (d) Nothing in this SECTION 4.4 shall be deemed to prejudice the right of
any Lender to recover from any Issuer any amounts made available by such Lender
to such Issuer pursuant to this Section in the event that it is finally
determined by a court of competent jurisdiction that the payment with respect to
a Letter of Credit by such Issuer in respect of which payment was made by such
Lender constituted gross negligence or wilful misconduct on the part of such
Issuer.  Each Issuer shall distribute to each other Lender which has paid all
amounts payable by it under this SECTION 4.4 with respect to any Letter of
Credit issued by such Issuer such other Lender's Percentage of all payments
received by such Issuer from the Revolving Borrower 

                                      -56-
<PAGE>

in reimbursement of drawings honored by such Issuer under such Letter of 
Credit when such payments are received.

     SECTION 4.5  DISBURSEMENTS.  Each Issuer will notify the Revolving Borrower
and the Administrative Agent promptly of the presentment for payment of any
Letter of Credit, together with notice of the date (a "DISBURSEMENT DATE") such
payment shall be made.  Subject to the terms and provisions of such Letter of
Credit, the applicable Issuer shall make such payment to the beneficiary (or its
designee) of such Letter of Credit.  Prior to 10:00 a.m., San Francisco time, on
the Disbursement Date, the Revolving Borrower will reimburse the applicable
Issuer for all amounts which it has disbursed or is required to disburse under
the Letter of Credit on such date.  To the extent the applicable Issuer is not
reimbursed in full in accordance with the THIRD SENTENCE of this Section, the
Revolving Borrower's Reimbursement Obligation shall accrue interest at a
fluctuating rate equal to the Alternate Base Rate through and including the
first Business Day after the Disbursement Date, and thereafter at a fluctuating
rate equal to the Alternate Base Rate plus a margin of 2.0% PER ANNUM, in each
case, payable on demand.  The Revolving Borrower may borrow Revolving Loans
hereunder in order to pay any Reimbursement Obligation, subject to the terms and
conditions hereof (except for the minimum amounts for Borrowings set forth in
SECTION 2.3) including satisfaction of the conditions set forth in SECTION 6.2,
PROVIDED, HOWEVER, for the purpose of determining the availability of the
Commitments to make Revolving Loans immediately prior to giving effect to the
application of the proceeds of such Revolving Loans, such Reimbursement
Obligation shall be deemed not to be outstanding at such time.

     SECTION 4.6  REIMBURSEMENT.  The Revolving Borrower's obligation (a
"REIMBURSEMENT OBLIGATION") under SECTION 4.5 to reimburse an Issuer with
respect to each Disbursement (including interest thereon), and each Lender's
obligation to make participation payments in each drawing which has not been
reimbursed by the Revolving Borrower, shall be absolute and unconditional under
any and all circumstances and irrespective of any setoff, recoupment,
counterclaim, or defense to payment which the Revolving Borrower may have or
have had against any Lender or any beneficiary of a Letter of Credit, including
any defense based upon the occurrence of any Default, any draft, demand or
certificate or other document presented under a Letter of Credit proving to be
forged, fraudulent, invalid or insufficient, the failure of any Disbursement to
conform to the terms of the applicable Letter of Credit (if, in the applicable
Issuer's good faith opinion, such Disbursement is determined to be appropriate)
or any non-application or misapplication by the beneficiary of the proceeds of
such Disbursement, or the legality, validity, form, regularity, or
enforceability of such Letter of Credit; PROVIDED, HOWEVER, that nothing herein
shall adversely affect the right of the Revolving Borrower to commence any
proceeding 

                                      -57-
<PAGE>

against the applicable Issuer for any wrongful Disbursement made by such 
Issuer under a Letter of Credit as a result of acts or omissions constituting 
gross negligence or wilful misconduct on the part of such Issuer.

     SECTION 4.7  DEEMED DISBURSEMENTS.  Upon the occurrence and during the
continuation of any Event of Default after the Restatement Effective Date or the
occurrence of the Revolving Commitment Termination Date, an amount equal to that
portion of Letter of Credit Outstandings attributable to outstanding and undrawn
Letters of Credit shall, at the election of the applicable Issuer acting on
instructions from the Majority Lenders, and without demand upon or notice to the
Revolving Borrower, be deemed to have been paid or disbursed by such Issuer
under such Letters of Credit (notwithstanding that such amount may not in fact
have been so paid or disbursed), and, upon notification by such Issuer to the
Administrative Agent and the Revolving Borrower of its obligations under this
Section, the Revolving Borrower shall be immediately obligated to pay to the
Administrative Agent, the amount deemed to have been so paid or disbursed by
such Issuer.  Any amounts so received by the Administrative Agent from the
Revolving Borrower pursuant to this SECTION 4.7 shall be held by the
Administrative Agent in a segregated account as collateral security for the
repayment of the Revolving Borrower's Obligations in connection with the Letters
of Credit issued by such Issuer and, subject to the prior payment of such
Obligations, the other Obligations of the Revolving Borrower.  The Revolving
Borrower hereby assigns and pledges to the Administrative Agent, for the benefit
of the applicable Issuer, and hereby grants to the Administrative Agent, for the
benefit of the applicable Issuer, a security interest in and lien upon such
account and all deposits in such account, all investments arising out of such
funds, all claims thereunder or in connection therewith and all cash,
securities, rights and other property at any time and from time to time
received, receivable or otherwise distributed in respect of such account, such
funds or such investments.  At such time when all Events of Default shall have
been cured or waived, the Administrative Agent shall return to the Revolving
Borrower all amounts then on deposit with the Administrative Agent pursuant to
this Section.  All amounts on deposit pursuant to this Section shall, until
their application to any Reimbursement Obligation or other Obligation or their
return to the Revolving Borrower, as the case may be, bear interest at the daily
average Federal Funds Rate from time to time in effect (net of the costs of any
reserve requirements, in respect of amounts on deposit pursuant to this Section,
pursuant to F.R.S. Board Regulation D), which interest shall be held by the
Administrative Agent as additional collateral security for the repayment of the
Obligations.

     SECTION 4.8  NATURE OF REIMBURSEMENT OBLIGATIONS.  The Revolving
Borrower shall assume all risks of the acts, omissions, 

                                      -58-

or misuse of any Letter of Credit by the beneficiary thereof.  Neither any 
Issuer nor any Lender (except to the extent of its own gross negligence or 
wilful misconduct) shall be responsible for:

          (a) the form, validity, sufficiency, accuracy, genuineness, or legal
     effect of any Letter of Credit or any document submitted by any party in
     connection with the application for and issuance of a Letter of Credit,
     even if it should in fact prove to be in any or all respects invalid,
     insufficient, inaccurate, fraudulent, or forged;

          (b) the form, validity, sufficiency, accuracy, genuineness, or legal
     effect of any instrument transferring or assigning or purporting to
     transfer or assign a Letter of Credit or the rights or benefits thereunder
     or proceeds thereof in whole or in part, which may prove to be invalid or
     ineffective for any reason;

          (c) failure of the beneficiary to comply fully with conditions
     required in order to demand payment under a Letter of Credit;

          (d) errors, omissions, interruptions, or delays in transmission or
     delivery of any messages, by mail, cable, telegraph, telex, or otherwise;
     or

          (e) any loss or delay in the transmission or otherwise of any document
     or draft required in order to make a Disbursement under a Letter of Credit
     or of the proceeds thereof.

None of the foregoing shall affect, impair, or prevent the vesting of any of the
rights or powers granted any Issuer or any Lender hereunder.  In furtherance and
extension, and not in limitation or derogation, of any of the foregoing, any
action taken or omitted to be taken by any Issuer in good faith shall be binding
upon the Revolving Borrower and shall not put such Issuer under any resulting
liability to the Revolving Borrower.

     SECTION 4.9  INDEMNITY.  The Revolving Borrower hereby agrees to protect,
indemnify, pay and save each Issuer, the Administrative Agent and each Lender
harmless from and against any and all claims, demands, liabilities, damages,
losses, costs, charges and expenses (including reasonable attorneys' fees and
allocated costs of internal counsel) which such Issuer, Co-Agent or Lender may
incur or be subject to as a consequence, direct or indirect, of

          (a) the issuance of the Letters of Credit, other than as a result of
     the gross negligence or wilful misconduct of 

                                      -59-
<PAGE>

     such Issuer, the Administrative Agent or Lender as determined by a court 
     of competent jurisdiction, or
     
          (b) the failure of such Issuer, the Administrative Agent or Lender to
     honor a drawing under any Letter of Credit as a result of any applicable
     act or omission, whether rightful or wrongful, of any present or future de
     jure or de facto government or governmental authority.

     SECTION 4.10  CONFLICTS WITH LETTER OF CREDIT RELATED DOCUMENTS.  In the
event of any conflict between this Agreement and any of the agreements and
instruments entered into by the Revolving Borrower with (or in favor of) any
Issuer and relating to any Letter of Credit (other than the Letter of Credit
itself), including any Issuance Request, this Agreement shall control.


                                    ARTICLE V

                  CERTAIN EURODOLLAR RATE AND OTHER PROVISIONS

     SECTION 5.1  EURODOLLAR RATE LENDING UNLAWFUL.  If any Lender shall
determine (which determination shall, upon notice thereof to each Borrower and
the Lenders, be conclusive and binding on such Borrower) that the introduction
of or any change in or in the interpretation of any law makes it unlawful, or
any central bank or other governmental authority asserts that it is unlawful,
for such Lender to make Bid Loans based upon the Eurodollar Rate or to make,
continue or maintain any Loan as, or to convert any Loan into, a Eurodollar
Committed Loan of a certain Type, the obligations of such Lender to make,
continue, maintain or convert into any such Loans shall, upon such
determination, forthwith be suspended until such Lender shall notify the
Administrative Agent that the circumstances causing such suspension no longer
exist, and all outstanding Bid Loans based upon the Eurodollar Rate and all
outstanding Eurodollar Committed Loans made by such Lender shall automatically
convert into Base Rate Committed Loans at the end of the then current Interest
Periods with respect thereto or sooner, if required by such law or assertion.

     SECTION 5.2  DEPOSITS UNAVAILABLE.  If the Majority Lenders shall have
determined that

          (a) Dollar deposits in the relevant amount and for the relevant
     Interest Period are not available to the Administrative Agent in its
     relevant market; or

          (b)  by reason of circumstances affecting their relevant eurodollar
     markets, adequate means do not exist for ascertaining the interest rate
     applicable hereunder to Bid 

                                      -60-
<PAGE>

     Loans based on the Eurodollar Rate or to Eurodollar Committed Loans,

then, upon notice from the Administrative Agent to each Borrower and the
Lenders, the obligations of all Lenders under SECTION 2.3 and SECTION 2.4 to
make any Bid Loans based on the Eurodollar Rate or to make or continue any Loans
as, or to convert any Loans into, Eurodollar Committed Loans shall forthwith be
suspended until the Administrative Agent shall notify such Borrower and the
Lenders that the circumstances causing such suspension no longer exist.

     SECTION 5.3  INCREASED EURODOLLAR LOAN COSTS, ETC.  Each Borrower agrees to
reimburse each Lender for any increase in the cost to such Lender of, or any
reduction in the amount of any sum receivable by such Lender in respect of,
making, continuing or maintaining (or of its obligation to make, continue or
maintain) any Loans as, or, if applicable, of converting (or of its obligation
to convert) any Loans into, Bid Loans based on the Eurodollar Rate or Eurodollar
Committed Loans.  Such Lender shall promptly notify the Administrative Agent and
each Borrower in writing of the occurrence of any such event, such notice to
state, in reasonable detail, the reasons therefor and the additional amount
required fully to compensate such Lender for such increased cost or reduced
amount (which shall include calculations in reasonable detail).  Such additional
amounts shall be payable by each Borrower directly to such Lender within five
Business Days of its receipt of such notice, and such notice shall, in the
absence of manifest error, be conclusive and binding on such Borrower.

     SECTION 5.4  FUNDING LOSSES.  In the event any Lender shall incur any loss
or expense (including any loss or expense incurred by reason of the liquidation
or reemployment of deposits or other funds acquired by such Lender to make,
continue or maintain any portion of the principal amount of any Loan as, or, if
applicable, to convert any portion of the principal amount of any Loan into, a
Bid Loan based upon the Eurodollar Rate or a Eurodollar Committed Loan) as a
result of

          (a) any conversion or repayment or prepayment of the principal amount
     of any Bid Loans or Eurodollar Committed Loans on a date other than the
     scheduled last day of the Interest Period applicable thereto, whether
     pursuant to SECTION 3.1 or otherwise;

          (b) any Loans not being made in accordance with the Borrowing Request
     therefor; or

          (c) any Loans not being continued as, or converted into, Eurodollar
     Committed Loans in accordance with the Continuation/Conversion Notice
     therefor; or

                                      -61-
<PAGE>

          (d) receipt by such Lender of a payment in respect of its Loans on a
     date other than the scheduled last day of an Interest Period applicable
     thereto as a consequence of the assignments which take place on the
     Restatement Effective Date pursuant to SECTION 5.13,

then, upon the written notice of such Lender to each Borrower (with a copy to
the Administrative Agent), which notice shall set forth the basis for requesting
such reimbursement, such Borrower shall, within five Business Days of its
receipt thereof, pay directly to such Lender such amount as will (in the
reasonable determination of such Lender) reimburse such Lender for such loss or
expense incurred with respect to Loans to such Borrower.  Such written notice
(which shall include calculations in reasonable detail) shall, in the absence of
manifest error, be conclusive and binding on such Borrower.

     SECTION 5.5  INCREASED CAPITAL COSTS.  If any change in, or
the introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in since the Restatement Effective Date of, any law or regulation,
directive, guideline, decision or request (whether or not having the force of
law) of any court, central bank, regulator or other governmental authority
affects or would affect the amount of capital required or expected to be
maintained by any Lender or any Person controlling such Lender, and such Lender
determines (in its sole and absolute discretion) that the rate of return on its
or such controlling Person's capital as a consequence of its Commitments,
issuance of or participation in Letters of Credit or the Loans made by such
Lender is reduced to a level below that which such Lender or such controlling
Person could have achieved but for the occurrence of any such circumstance,
then, in any such case upon notice from time to time by such Lender to each
Borrower, such Borrower shall, within five Business Days of its receipt thereof
pay directly to such Lender additional amounts sufficient to compensate such
Lender or such controlling Person for such reduction in rate of return with
respect to such Borrower.  A statement of such Lender as to any such additional
amount or amounts (including calculations thereof in reasonable detail) shall,
in the absence of manifest error, be conclusive and binding on each Borrower.
In determining such amount, such Lender may use any method of averaging and
attribution that it (in its sole and absolute discretion) shall deem applicable.

     SECTION 5.6  TAXES. (a)  All payments by each Borrower of principal of, and
interest on, the Loans and all other amounts payable hereunder shall be made
free and clear of and without deduction for any present or future income,
excise, stamp or franchise taxes and other taxes, fees, duties, withholdings or
other charges of any nature whatsoever imposed by any taxing authority, but
excluding franchise taxes and taxes imposed on or measured by any Lender's net
income or receipts (such non-

                                      -62-
<PAGE>

excluded items being called "TAXES").  In the event that any withholding or 
deduction from any payment to be made by either Borrower hereunder is 
required in respect of any Taxes pursuant to any applicable law, rule or 
regulation, then such Borrower will

          (i) pay directly to the relevant authority the full amount required to
     be so withheld or deducted;

          (ii) promptly forward to the Administrative Agent an official receipt
     or other documentation satisfactory to the Administrative Agent evidencing
     such payment to such authority; and

          (iii) pay to the Administrative Agent for the account of the Lenders
     such additional amount or amounts as is necessary to ensure that the net
     amount actually received by each Lender will equal the full amount such
     Lender would have received had no such withholding or deduction been
     required.

Moreover, if any Taxes are directly asserted against the Administrative Agent or
any Lender with respect to any payment received by the Administrative Agent or
such Lender hereunder, the Administrative Agent or such Lender may pay such
Taxes and the applicable Borrower will promptly pay such additional amounts
(including any penalties, interest or expenses) as is necessary in order that
the net amount received by such person after the payment of such Taxes
(including any Taxes on such additional amount) shall equal the amount such
person would have received had not such Taxes been asserted.

     (b) If the applicable Borrower fails to pay any Taxes when due to the
appropriate taxing authority or fails to remit to the Administrative Agent, for
the account of the Administrative Agent or Lenders, the required receipts or
other required documentary evidence, such Borrower shall indemnify the
Administrative Agent and 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.  For purposes of this SECTION 5.6, a distribution
hereunder by the Administrative Agent or any Lender to or for the account of any
Lender shall be deemed a payment by the applicable Borrower.

     Each Lender that is organized under the laws of a jurisdiction other than
the United States shall, prior to the date such Lender becomes a party to this
Agreement and in a timely fashion thereafter, execute and deliver to each
Borrower and the Administrative Agent, one or more (as such Borrower or the
Administrative Agent may reasonably request) United States Internal Revenue
Service Forms 4224 or Forms 1001 or such other forms or documents (or successor
forms or documents), 

                                      -63-
<PAGE>

appropriately completed, as may be applicable to establish the extent, if 
any, to which a payment to such Lender is exempt from withholding or 
deduction of Taxes.

     SECTION 5.7  PAYMENTS, COMPUTATIONS, ETC.  Unless otherwise expressly
provided, all payments by each Borrower pursuant to this Agreement, the Notes or
any other Loan Document shall be made by such Borrower to the Administrative
Agent for the PRO RATA account of the Lenders entitled to receive such payment.
All such payments required to be made to the Administrative Agent shall be made,
without setoff, deduction or counterclaim, not later than 9:00 a.m., San
Francisco time, on the date due, in same day or immediately available funds, to
such account as the Administrative Agent shall specify from time to time by
notice to such Borrower.  Funds received after that time shall be deemed to have
been received by the Administrative Agent on the next succeeding Business Day.
The Administrative Agent shall promptly remit in same day funds to each Lender
its share, if any, of such payments received by the Administrative Agent for the
account of such Lender.  All interest and fees shall be computed on the basis of
the actual number of days (including the first day but excluding the last day)
occurring during the period for which such interest or fee is payable over a
year comprised of 360 days (or, in the case of interest on a Base Rate Committed
Loan (other than when calculated with respect to the Federal Funds Rate), 365
days or, if appropriate, 366 days).  Whenever any payment to be made shall
otherwise be due on a day which is not a Business Day, such payment shall
(except as otherwise required by CLAUSE (c) of the definition of the term
"INTEREST PERIOD" with respect to Eurodollar Committed Loans) be made on the
next succeeding Business Day and such extension of time shall be included in
computing interest and fees, if any, in connection with such payment.

     SECTION 5.8  SHARING OF PAYMENTS.  If any Lender shall obtain any payment
or other recovery (whether voluntary, involuntary, by application of setoff or
otherwise) on account of any Committed Loan (other than pursuant to the terms of
SECTIONS 5.3, 5.4 and 5.5) or Letter of Credit in excess of its PRO RATA share
of payments then or therewith obtained by all Lenders, such Lender shall
purchase from the other Lenders such participations in Committed Loans made by
them and/or Letters of Credit as shall be necessary to cause such purchasing
Lender to share the excess payment or other recovery ratably with each of them;
PROVIDED, HOWEVER, that if all or any portion of the excess payment or other
recovery is thereafter recovered from such purchasing Lender, the purchase shall
be rescinded and each Lender which has sold a participation to the purchasing
Lender shall repay to the purchasing Lender the purchase price to the ratable
extent of such recovery together with an amount equal to such selling Lender's
ratable share (according to the proportion of

                                      -64-
<PAGE>

          (a)  the amount of such selling Lender's required repayment to the
     purchasing Lender

TO

          (b)  the total amount so recovered from the purchasing Lender)

of any interest or other amount paid or payable by the purchasing Lender in
respect of the total amount so recovered.  Each Borrower agrees that any Lender
so purchasing a participation from another Lender pursuant to this Section may,
to the fullest extent permitted by law, exercise all its rights of payment
(including set-off, but subject to SECTION 5.9) with respect to such
participation as fully as if such Lender were the direct creditor of such
Borrower in the amount of such participation.  If under any applicable
bankruptcy, insolvency or other similar law, any Lender receives a secured claim
in lieu of a setoff to which this Section applies, such Lender shall, to the
extent practicable, exercise its rights in respect of such secured claim in a
manner consistent with the rights of the Lenders entitled under this Section to
share in the benefits of any recovery on such secured claim.

     SECTION 5.9  SET-OFF.  In addition to any rights and remedies of the
Lenders provided by law, if an Event of Default exists, each Lender is
authorized at any time and from time to time, without prior notice to either
Borrower, any such notice being waived by such Borrower to the fullest extent
permitted by law, to set off and apply any and all deposits (general or special,
time or demand, provisional or final) at any time held by, and other
indebtedness at any time owing by, such Lender to or for the credit or the
account of each Borrower against any and all Obligations owing to such Lender by
such Borrower, now or hereafter existing, irrespective of whether or not the
Administrative Agent or such Lender shall have made demand under this Agreement
or any Loan Document and although such Obligations may be contingent or
unmatured.  Each Lender agrees promptly to notify each Borrower and the
Administrative Agent after any such set-off and application made by such Lender;
PROVIDED, HOWEVER, that the failure to give such notice shall not affect the
validity of such set-off and application.  The rights of each Lender under this
SECTION 5.9 are in addition to the other rights and remedies (including other
rights of set-off) which the Lender may have.  Any Lender or Swingline Lender
having outstanding Committed Loans, Swingline Loans and Bid Loans at any time a
right of set-off is exercised by such Lender or Swingline Lender shall apply the
proceeds of such set-off first to such Lender's Committed Loans, until its
Committed Loans are reduced to zero, then to its Swingline Loans, and thereafter
to its Bid Loans.  NOTWITHSTANDING THE FOREGOING, NO LENDER SHALL EXERCISE, OR
ATTEMPT TO EXERCISE, ANY RIGHT OF SET-OFF, BANKER'S LIEN, OR THE 

                                      -65-
<PAGE>

LIKE ARISING UNDER OR IN CONNECTION WITH THE LOAN DOCUMENTS AGAINST ANY 
DEPOSIT ACCOUNT OR PROPERTY OF EITHER BORROWER OR ANY SUBSIDIARY OF SUCH 
BORROWER HELD OR MAINTAINED BY THE LENDER WITHOUT THE PRIOR WRITTEN CONSENT 
OF THE MAJORITY LENDERS AND THE ADMINISTRATIVE AGENT.

     SECTION 5.10  USE OF PROCEEDS.  Each Borrower shall apply the proceeds of
each Borrowing in accordance with RECITAL G, PROVIDED, that, without limiting
the foregoing, no proceeds of any Loan will be used to acquire or carry any
equity security of a class which is registered pursuant to Section 12 of the
Securities Exchange Act of 1934, as amended, or any "margin stock", as defined
in F.R.S. Board Regulation U except for Approved Acquisitions in compliance with
F.R.S. Board Regulation U.

     SECTION 5.11   OTHER INCREASED COSTS.  If by reason of

          (a) any change in applicable law, regulation, rule, decree or
     regulatory requirement or any change in the interpretation or application
     by any judicial or regulatory authority of any law, regulation, rule,
     decree or regulatory requirement, or

          (b) compliance by any Lender or any Issuer with any direction, request
     or requirement (whether or not having the force of law) of any governmental
     or monetary authority, including Regulation D of the F.R.S. Board:

               (i) any Lender or any Issuer shall be subject to any tax (other
          than taxes on net income and franchises), levy, charge or withholding
          of any nature or to any variation thereof or to any penalty with
          respect to the maintenance or fulfillment of its obligations under
          this Agreement, whether directly or by such being imposed on or
          suffered by such Lender or Issuer;

               (ii) any reserve, deposit or similar requirement is or shall be
          applicable, imposed or modified in respect of any Letters of Credit
          issued by any Issuer or participations therein purchased by any Lender
          or any Commitment or Loans made by any Lender, but excluding with
          respect to any Eurodollar Committed Loan any such requirement included
          in the calculation of the Eurodollar Rate (Reserve Adjusted); or

               (iii) there shall be imposed on any Issuer any other condition
          regarding any Letter of Credit or any other condition on any Lender
          regarding this Agreement, any Commitment and Loans and any
          participation in any Letter of Credit;

                                      -66-
<PAGE>

and the result of the foregoing is directly or indirectly to increase the cost
to such Issuer or such Lender of issuing, making or maintaining its Commitment,
any Loans or any Letter of Credit or of purchasing or maintaining any
participation therein or making any Loan or to reduce any amount receivable in
respect of any such Letter of Credit or any such Commitment or Loan by such
Issuer or such Lender, as applicable, then and in any such case such Issuer or
such Lender, as applicable, may, at any time after the additional cost is
incurred or the amount received is reduced, notify each Borrower thereof, and
such Borrower shall pay on demand such amounts as such Issuer or Lender, as
applicable, may specify to be necessary to compensate such Issuer or Lender, as
applicable, for such additional cost or reduced receipt attributable to such
Borrower, together with interest on such amount from the date demanded until
payment in full thereof at a rate equal at all times to the Alternate Base Rate.
The determination by such Issuer or Lender, as applicable, of any amount due
pursuant to this Section, as set forth in a statement setting forth the
calculation thereof in reasonable detail, shall, in the absence of manifest
error, be final and conclusive and binding on all of the parties hereto.

     SECTION 5.12  OBLIGATION TO MITIGATE; SUBSTITUTION OF LENDERS.   (a)  Each
Lender agrees that as promptly as practicable after it becomes aware of the
occurrence of an event that would entitle it to give notice pursuant to this
ARTICLE V, and in any event if so requested by either Borrower, each Lender
shall use reasonable efforts to make, fund or maintain its affected Loans based
on the Eurodollar Rate through another Domestic Office, or a lending office
outside of the United States, if as a result thereof the increased costs would
be avoided or materially reduced or the illegality would thereby cease to exist
and if, in the opinion of such Lender, the making, funding or maintaining of
such Loans through such other office would not be disadvantageous to such Lender
or contrary to such Lender's normal banking practices.

     (b)  Upon the receipt by either Borrower from any Lender (an "AFFECTED
LENDER") of a request for compensation or payment under this ARTICLE V, such
Borrower may:  (i) request one or more of the other Lenders to acquire and
assume (in such Lender's sole discretion) all or part of such Affected Lender's
Loans and Commitments or Swingline Commitment, as the case may be; or (ii)
designate a replacement bank or financial institution to acquire and assume all
or part of such Affected Lender's Loans and Commitments or Swingline Commitment,
as the case may be.  Any such designation of a replacement bank or financial
institution under CLAUSE (ii) shall be subject to the prior written consent of
the Administrative Agent and the other Lenders (which consent shall not be
unreasonably withheld).  Nothing in this CLAUSE (b) shall relieve either
Borrower of any obligation to pay any 

                                     -67-
<PAGE>

amounts accrued under this ARTICLE V prior to the date any Lender is replaced.

     SECTION 5.13  CERTAIN RESTATEMENT EFFECTIVE DATE TRANSITIONAL MATTERS.

          (a) On the Restatement Effective Date, each Lender hereby sells and
     assigns, without recourse, an amount of Loans equal to the product of (i)
     the excess (if any) of its Original Percentage over its Restated Percentage
     times (ii) the aggregate principal amount of Loans outstanding on such date
     and each Lender hereby purchases an amount of Loans equal to the product of
     (i) the excess (if any) of its Restated Percentage over its Original
     Percentage times (ii) the aggregate principal amount of Loans outstanding
     on such date.  Each Lender selling Loans under this SECTION 5.13 shall be
     deemed to have sold (and each Lender purchasing Loans shall be deemed to
     have purchased) a PRO RATA portion (based on the aggregate principal amount
     of Loans then outstanding) of each of such selling Lender's Loans.
     Payments by each Lender purchasing Loans under this SECTION 5.13 shall be
     made to the Administrative Agent not later than 9:00 a.m., San Francisco
     time in immediately available funds, without setoff, deduction or
     counterclaim, for the PRO RATA account (based upon the outstanding
     principal amount of Loans being sold) of each selling Lender in an amount
     equal to the aggregate principal amount of outstanding Loans purchased by
     such Lender.

          (b) On and after the Restatement Effective Date, each Lender shall be
     entitled to receive commitment fees under SECTION 3.3.1, letter of credit
     fees under SECTION 3.3.5 and interest on Loans and on any other amount due
     under any Loan Document, in each case, (i) accrued and unpaid before the
     Restatement Effective Date in accordance with its Original Percentage and
     at the applicable rates then in effect under the Original Credit Agreement
     and (ii) accrued on and after the Restatement Effective Date in accordance
     with its Restated Percentage and at the applicable rates under this
     Agreement.

          (c)  Each Lender acknowledges and agrees that in accordance with
     SECTION 4.4 it shall be deemed to have participated in the issuance of each
     Letter of Credit issued pursuant to SECTION 4.2 (including, without
     limitation, Letters of Credit issued prior to the Restatement Effective
     Date) in accordance with its Restated Percentage.

          (d)  On and after the Restatement Effective Date, to the extent that
     any commitment and the other rights and obligations of any Lender existing
     at the time immediately preceding the Restatement Effective Date have been
     assigned 

                                      -68-
<PAGE>

     or delegated, as applicable, to any Lender under this Agreement, such 
     Lender hereby assumes such commitment and other obligations and shall
     have the rights and obligations of a Lender hereunder and under the other
     Loan Documents and, to the extent that any commitment and other obligations
     of any Lender existing at the time immediately preceding the Restatement
     Effective Date have been delegated by any Lender pursuant to this
     Agreement, such Lender shall be released from such commitment and its
     obligations thereunder and under the other Loan Documents.


                                   ARTICLE VI

                              CONDITIONS PRECEDENT

     SECTION 6.1  CONDITIONS TO RESTATEMENT EFFECTIVE DATE.  Unless otherwise
terminated pursuant to SECTION 6.4, this Agreement shall become effective on the
date (the "RESTATEMENT EFFECTIVE DATE") the conditions precedent set forth in
this SECTION 6.1 have been satisfied:

     SECTION 6.1.1  AGREEMENT.  The Administrative Agent shall have received
counterparts hereof executed on behalf of each Borrower, each Co-Agent and each
Lender (or notice thereof satisfactory to the Administrative Agent) shall have

     SECTION 6.1.2  RESOLUTIONS, ETC.  The Administrative Agent shall have
received from each Obligor a certificate, dated the Restatement Effective Date,
of its Secretary or Assistant Secretary as to

          (a) resolutions of its Board of Directors then in full force and
     effect authorizing the execution, delivery and performance of this
     Agreement, the Notes and each other Loan Document to be executed by it; and

          (b) the incumbency and signatures of those of its officers or other
     designees authorized to act with respect to this Agreement, the Notes and

<PAGE>


Effective Date (in exchange for Notes previously delivered by the Borrowers
under the Original Credit Agreement) for the account of such Lender, its

examined without qualification by Arthur Andersen LLP), copies of which have
been furnished to the Administrative Agent and each Lender, have been prepared
in accordance with GAAP consistently applied (except, in the case of the

Settlement Agreement Modification would, or could reasonably be expected to:

          (a)  increase or accelerate the payment date of any amounts payable by
     the Revolving Borrower or any of its Subsidiaries under the Settlement
     Agreements, or require the Revolving Borrower or any of its Subsidiaries to

     them under the Settlement Agreements;

          (b)  reduce or delay in any material respect the payment or funding of
     any amounts which the parties to the Settlement Agreements (other than the

     behalf of the Revolving Borrower or any of its Subsidiaries (including
     without limitation (i) the payment of any claims, judgments, settlements or
     other amounts payable in respect of asbestos or Asbestos Litigation, and
     (ii) the funding of any trusts, escrows or other funding mechanisms
     provided for in the Settlement Agreements);

          (c)  change in any material respect the "spendthrift" limitations
     applicable to any payments which are to be made from any trusts, escrows or
     other funds which are established or to be established pursuant to the
     Settlement Agreements;

          (d)  modify in any way which is materially adverse to the Revolving
     Borrower or any of its Subsidiaries any of the components contained in the

     To the extent reasonably practicable prior to entering into any Settlement
Agreement Modification or other modification of any of the terms, or provisions
contained in or applicable to any of the Settlement Agreements, the Revolving
Borrower will deliver to the Administrative Agent a copy thereof and, if the
Revolving Borrower believes that such Settlement Agreement Modification does not
violate this SECTION 8.2.9, a written explanation of the reason for such belief.

                                      -92-

PROVIDED that no Event of Default shall occur under this SECTION 9.1.12 if

Borrower executes and delivers to the Administrative Agent the Collateral
Documents substantially in the form in effect at the time immediately preceding
the Restatement Effective Date, in each case, together with the items set forth

                            THE ADMINISTRATIVE AGENT


     SECTION 10.1  APPOINTMENT AND AUTHORIZATION.  Each of the Lenders hereby
irrevocably appoints, designates and authorizes the Administrative Agent to take
such action on its behalf under the provisions of this Agreement and each other
Loan Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document, the Administrative Agent shall have no
duties or responsibilities, except those expressly set forth herein, nor shall
the Administrative Agent have or be deemed to have 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.

     SECTION 10.2  DELEGATION OF DUTIES.  The Administrative Agent may execute
any of its duties under this Agreement or any other Loan Document by or through
agents, employees 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 agent or
attorney-in-fact that it selects with reasonable care.

     SECTION 10.3  LIABILITY OF ADMINISTRATIVE AGENT AND ISSUERS.  None of the
Administrative Agent/Related Persons shall (i) be liable for any action taken or
omitted to be taken by any of them under or in connection with this Agreement or
any other Loan Document (except for its own gross negligence or willful
misconduct), or (ii) be responsible in any manner to any of the Lenders for any
recital, statement, representation or warranty made by either Borrower or any
Subsidiary of such Borrower, or any officer thereof, contained in this Agreement
or in 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 validity, effectiveness, genuineness, enforceability or sufficiency of this
Agreement or any other Loan Document, or for any failure of either Borrower or
any other party to any Loan Document to perform its obligations hereunder or
thereunder.  No Administrative Agent/Related Person shall 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

                                      -98-
<PAGE>

records of either Borrower or any of its Subsidiaries or Affiliates.

     SECTION 10.4   RELIANCE BY ADMINISTRATIVE AGENT.

          (a)  The Administrative Agent shall be entitled to rely, and shall be
fully protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement 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 either
Borrower), independent accountants and other experts selected by 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
Majority Lenders or Lenders as it deems appropriate and, if it so requests, it
shall first be indemnified to its satisfaction by the Lenders against any and
all liability and expense which 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
or any other Loan Document in accordance with a request or consent of the
Majority Lenders or Lenders, as applicable, and such request and any action
taken or failure to act pursuant thereto shall be binding upon all of the
Lenders.

          (b)  For purposes of determining compliance with the conditions
specified in ARTICLE VI, each Lender that has executed this Agreement shall be
deemed to have consented to, approved or accepted or to be satisfied with each
document or other matter either sent or made available by the Administrative
Agent to such Lender for consent, approval, acceptance or satisfaction, or
required thereunder to be consented to or approved by or acceptable or
satisfactory to such Lender, unless an officer of the Administrative Agent
responsible for the transactions contemplated by the Loan Documents shall have
received notice from such Lender prior to the applicable Credit Extension
specifying its objection thereto and either such objection shall not have been
withdrawn by notice to the Administrative Agent to that effect or (with respect
to any Loan) such Lender shall not have made available to the Administrative
Agent such Lender's ratable portion of any Borrowing.

     SECTION 10.5   NOTICE OF DEFAULT.  The Administrative Agent shall be deemed
to have knowledge or notice of the occurrence of any Default, except with
respect to defaults in the payment of principal, interest and fees required to
be paid to the Administrative Agent for the account of the Lenders, unless the
Administrative Agent shall have received written notice from a 

                                      -99-
<PAGE>

Lender or either Borrower referring to this Agreement, describing such 
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 will 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 requested by the Majority Lenders in accordance with ARTICLE IX; 
PROVIDED, HOWEVER, that unless and until the Administrative Agent shall have 
received any such request, the Administrative Agent may (but shall not be 
obligated to) take such action, or refrain from taking such action, subject 
to the provisions of SECTION 9.3, with respect to such Default or Event of 
Default as it shall deem advisable or in the best interest of the Lenders.

     SECTION 10.6   CREDIT DECISION.  Each Lender expressly acknowledges that
none of the Administrative Agent/Related Persons has made any representation or
warranty to it and that no act by the Administrative Agent hereinafter taken,
including any review of the affairs of either Borrower and its Subsidiaries,
shall be deemed to constitute any representation or warranty by the
Administrative Agent to any Lender.  Each Lender represents to the
Administrative Agent that it has, independently and without reliance upon the
Administrative Agent and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and
creditworthiness of each Borrower and its Subsidiaries, and all applicable bank
regulatory laws relating to the transactions contemplated thereby, and made its
own decision to enter into this Agreement and extend credit to each Borrower
hereunder.  Each Lender also represents that it will, independently and without
reliance upon the Administrative Agent and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, evaluations and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigations as
it deems necessary to inform itself as to the business, prospects, operations,
property, financial and other condition and creditworthiness of each Borrower.
Except for notices, reports and other documents expressly herein required to be
furnished to the Lenders by the Administrative Agent, the Administrative Agent
shall not have any duty or responsibility to provide any Lender with any credit
or other information concerning the business, prospects, operations, property,
financial and other condition or creditworthiness of either Borrower which may
come into the possession of any of the Administrative Agent/Related Persons.

     SECTION 10.7  INDEMNIFICATION.  The Lenders shall indemnify upon demand the
Administrative Agent/Related Persons and the Documentation Agent/Related Persons
(to the extent not reimbursed by or on behalf of either Borrower and without
limiting the obligation of each Borrower to do so), ratably according to its

                                     -100-

<PAGE>

respective Percentage from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses and
disbursements of any kind whatsoever which may at any time (including at any
time following the termination of the Letters of Credit, the repayment of the
Loans and the termination or resignation of the Administrative Agent or the
Documentation Agent, as applicable) be imposed on, incurred by or asserted
against any such Person in any way relating to or arising out of this Agreement
or any document contemplated by or referred to herein or therein or the
transactions contemplated hereby or thereby or any action taken or omitted by
any such Person under or in connection with any of the foregoing; PROVIDED,
HOWEVER, that no Lender shall be liable for the payment to the Administrative
Agent/Related Persons or Documentation Agent/Related Persons of any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting solely from such Person's
gross negligence or willful misconduct.  Without limitation of the foregoing,
each Lender shall reimburse the Administrative Agent and the Documentation Agent
upon demand for its ratable share according to its respective Percentage of any
reasonable costs or out-of-pocket expenses including the fees and disbursements
of legal counsel incurred by the Administrative Agent or the Documentation Agent
in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any document
contemplated by or referred to herein to the extent that the Administrative
Agent or the Documentation Agent is not reimbursed for such expenses by or on
behalf of either Borrower.  Without limiting the generality of the foregoing, if
the Internal Revenue Service or any authority of the United States or other
jurisdiction asserts a claim that Administrative Agent did not properly withhold
tax from amounts paid to or for the account of any Lender (because the
appropriate form was not delivered, was not properly executed, or because such
Lender failed to notify the Administrative Agent of a change in circumstances
which rendered the exemption from, or reduction of, withholding tax ineffective,
or for any other reason), such Lender shall indemnify Administrative Agent fully
for all amounts paid, directly or indirectly, by the Administrative Agent as tax
or otherwise, including penalties and interest, and including any taxes imposed
by any jurisdiction on the amounts payable to Administrative Agent under this
SECTION 10.7, together with all costs and out-of-pocket expenses, including the
fees and disbursements of legal counsel.  The obligation of the Lenders in this
Section shall survive the payment of all Obligations hereunder.

     SECTION 10.8  ADMINISTRATIVE AGENT IN INDIVIDUAL CAPACITY.  The
Administrative Agent and its Affiliates may make loans to, 

                                     -101-
<PAGE>

issue letters of credit for the account of, accept deposits from, acquire 
equity interests in and generally engage in any kind of banking, trust, 
financial advisory, underwriting or other business with each Borrower and its 
Subsidiaries and Affiliates as though it were not the Administrative Agent 
hereunder and without notice to or consent of the Lenders.  The Lenders 
acknowledge that, pursuant to such activities, the Administrative Agent or 
its Affiliates may receive information regarding either Borrower or its 
Subsidiaries or Affiliates (including information that may be subject to 
confidentiality obligations in favor of such Borrower or such Subsidiary or 
Affiliate) and acknowledge that the Administrative Agent shall be under no 
obligation to provide such information to them.  With respect to its Loans 
and participation in Letters of Credit, the Administrative Agent shall have 
the same rights and powers under this Agreement as any other 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.

     SECTION 10.9  SUCCESSOR ADMINISTRATIVE AGENT.  The Administrative Agent may
resign from its capacity as Administrative Agent upon 30 days' notice to the
Lenders.  If the Administrative Agent shall resign as Administrative Agent under
this Agreement, the Majority Lenders shall appoint from among the Lenders a
successor agent for the Lenders.  If no successor Administrative Agent is
appointed prior to the effective date of the resignation of a retiring
Administrative Agent, the Administrative Agent shall appoint, after consulting
with the Lenders and the Revolving Borrower, a successor agent from among the
Lenders.  Upon the acceptance of its appointment as successor agent hereunder,
such successor agent shall succeed to all the rights, powers and duties of the
retiring Administrative Agent and the term "Administrative Agent" shall mean
such successor agent and the retiring Administrative Agent's rights, powers and
duties as Administrative Agent shall be terminated.  After any retiring
Administrative Agent's resignation hereunder as Administrative Agent, the
provisions of this ARTICLE X and SECTIONS 11.3 and 11.4 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.  If no successor agent has accepted
appointment as Administrative Agent by the date which is 30 days following a
retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become effective
and the Banks shall perform all of the duties of the Administrative Agent
hereunder until such time, if any, as the Majority Lenders appoint a successor
agent as provided for above.

     SECTION 10.10  COLLATERAL MATTERS.

          (a)  The Revolving Borrower hereby requests the Administrative Agent,
the Documentation Agent and the Lenders to 

                                     -102-
<PAGE>

release the Collateral Documents and Collateral.  To induce the 
Administrative Agent, the Documentation Agent and the Lenders to consent to 
such release, the Revolving Borrower hereby certifies to each of them that:

               (i) no Default has occurred and is continuing on the Restatement
     Effective Date or shall have occurred and be continuing on the date of the
     release of the Collateral, both before and after giving effect to such
     release;

               (ii) the representations and warranties of each Borrower set
     forth in ARTICLE VII are true and correct on the Restatement Effective Date
     and shall be true and correct on the date of the release of the Collateral,
     both before and after giving effect to such release;

               (iii) a Settlement Agreement Approval Judgment has been issued
     and entered as to which any appeal (and subsequent remand, if any) has been
     finally decided and no further appeal or petition for certiorari can be
     taken or granted; and

               (iv) Arthur Andersen LLP has delivered its opinion with respect
     to the December 31, 1995 audited annual consolidated financial statements
     of the Revolving Borrower and its Subsidiaries and such opinion contains no
     Impermissible Qualification (including, without limitation, the Asbestos
     Qualification).

          (b)  The Documentation Agent and the Lenders hereby irrevocably
consent to the release of the Collateral Documents and the Collateral, and
authorize the Administrative Agent to release the Collateral Documents and any
Lien granted to or held by the Administrative Agent upon any Collateral.

          (c)  The Administrative Agent is hereby instructed by the Lenders to
sign all applicable agreements and other documents respecting the Collateral
release permitted hereunder.

     SECTION 10.11  FUNDING RELIANCE, ETC.  Unless the Administrative Agent
shall have been notified by telephone, confirmed in writing, by any Lender or
Bid Loan Lender by 3:00 p.m., San Francisco time, on the day prior to a
Borrowing that such Lender will not make available the amount which would
constitute its Percentage of such Borrowing on the date specified therefor, or
such Bid Loan Lender shall not make available the amount of its Bid Loan on the
date specified therefor the Administrative Agent may assume that such Lender or
Bid Loan Lender, as the case may be, has made such amount available to the
Administrative Agent and, in reliance upon such assumption, may (but shall not
be obligated to) make available to the applicable Borrower a corresponding
amount.  If and to the extent that such 

                                     -103-
<PAGE>

Lender shall not have made such amount available to the Administrative Agent, 
such Lender or Bid Loan Lender, as the case may be, and the applicable 
Borrower severally agree to repay the Administrative Agent forthwith on 
demand such corresponding amount together with interest thereon, for each day 
from the date the Administrative Agent made such amount available to such 
Borrower to the date such amount is repaid to the Administrative Agent, at 
the interest rate applicable at the time to Loans comprising such Borrowing.

     SECTION 10.12  COPIES, ETC.  The Administrative Agent will give prompt
notice to each Lender of each notice or request required or permitted to be
given to the Administrative Agent by each Borrower pursuant to the terms of this
Agreement or the other Loan Documents (unless concurrently delivered to the
Lenders by such Borrower).  The Administrative Agent will distribute to each
Lender each document or instrument received for its account and copies of all
other communications received by it from each Borrower for distribution to the
Lenders in accordance with the terms of this Agreement or the other Loan
Documents.

     SECTION 10.13  CO-AGENTS.  None of the Lenders identified on the facing
page or signature pages of this Agreement as a "co-agent" (other than BofA in
its capacity as Administrative Agent) or "documentation co-agent" shall have any
right, power, obligation, liability, responsibility or duty under this Agreement
other than those applicable to all Lenders as such.  Without limiting the
foregoing, none of the Lenders so identified as a "co-agent" (including BofA in
its capacity as Administrative Agent) or "documentation co-agent" shall have or
be deemed to have any fiduciary relationship with any Lender.  Each Lender
acknowledges that it has not relied, and will not rely, on any of the Lenders so
identified in deciding to enter into this Agreement or in taking or not taking
action hereunder.

     Section 10.14. LIMITATIONS ON INTEREST.  It is the intention of the parties
hereto to conform strictly to applicable usury laws and, anything herein to the
contrary notwithstanding, the obligations of the Borrowers to each Lender or
Co-Agent under this Agreement, the Notes, the Loan Documents and any other
document or instrument executed in connection herewith or therewith, shall be
subject to the limitation that payments of interest or of other amounts
constituting interest under applicable law to such Lender or Co-Agent shall not
be required to the extent that receipt thereof would be in excess of the Highest
Lawful Rate (as defined below), or otherwise contrary to provisions of law
applicable to such Lender or Co-Agent limiting rates of interest which may be
charged or collected by Lender or Co-Agent.  Accordingly, if the transactions or
the amount paid or otherwise agreed to be paid for the use, forbearance or
detention of money under this Agreement, the Notes, the Loan Documents and 

                                     -104-
<PAGE>

any other document or instrument executed in connection herewith or therewith 
would exceed the Highest Lawful Rate or otherwise be usurious under 
applicable law (including the federal and state laws of the United States of 
America, or of any other jurisdiction whose laws may be mandatorily 
applicable) with respect to any Lender or Co-Agent then, in that event, 
notwithstanding anything to the contrary in this Agreement or the Loan 
Documents and any other document or instrument executed in connection 
herewith or therewith, it is agreed as follows as to each Lender and Co-Agent:

               (a)  the provisions of this SECTION 10.14 shall govern and
          control over any other provision in this Agreement, the Notes,
          the Loan Documents and any other document or instrument executed
          in connection herewith or therewith and each provision set forth
          therein is hereby so limited;

               (b)  the aggregate of all consideration which constitutes
          interest under applicable law that is contracted for, charged or
          received under this Agreement, or under any of the other
          aforesaid agreements or otherwise in connection with this
          Agreement by such Lender or Co-Agent shall under no circumstances
          exceed the maximum amount of interest allowed by applicable law
          (such maximum lawful interest rate, if any, with respect to such
          Lender herein called the "HIGHEST LAWFUL RATE"), and all amounts
          owed under this Agreement, the Notes, the Loan Documents and any
          other document or instrument executed in connection herewith or
          therewith shall be held subject to reduction and (i) the amount
          of interest which would otherwise be payable to such Lender or
          Co-Agent hereunder and under the Loan Documents and any other
          document or instrument executed in connection herewith or
          therewith, shall be automatically reduced to the amount allowed
          under applicable law and (ii) any unearned interest paid by a
          Borrower in excess of the Highest Lawful Rate shall be credited
          to the applicable Borrower by such Lender or Co-Agent (or, if
          such consideration shall have been paid in full, refunded to the
          applicable Borrower);

               (c)  all sums paid, or agreed to be paid, to such Lender for
          the use, forbearance and detention of the indebtedness of a
          Borrower to such Lender or Co-Agent hereunder shall, to the
          extent permitted by applicable law, be amortized, prorated,
          allocated and spread throughout the full term of such
          indebtedness until payment in full so 

                                     -105-
<PAGE>

          that the actual rate of interest is uniform throughout the full 
          term thereof;

               (d)  if at any time the interest provided pursuant to this
          Agreement, together with any other fees, late charges and other
          sums payable pursuant to or in connection with this Agreement or
          any other Loan Document and deemed interest under applicable law,
          exceeds that amount which would have accrued at the Highest
          Lawful Rate, the amount of interest and any such fees, charges
          and sums to accrue to such Lender or Co-Agent pursuant to this
          Agreement or any other Loan Document shall be limited,
          notwithstanding anything to the contrary in this Agreement or any
          other Loan Document to that amount which would have accrued at
          the Highest Lawful Rate for such Lender or Co-Agent, as the case
          may be, but any subsequent reductions, as applicable, shall not
          reduce the interest to accrue pursuant to this Agreement below
          the Highest Lawful Rate for such Lender or Co-Agent until the
          total amount of interest payable to such Lender or Co-Agent
          (including all consideration which constitutes interest) equals
          the amount of interest which would have been payable to such
          Lender or Co-Agent (including all consideration which constitutes
          interest) assuming a varying rate per annum equal to the interest
          provided pursuant to SECTION 3.2 at all times in effect, PLUS the
          amount of fees which would have been received but for the effect
          of this SECTION 10.14.

     For purposes of Article 5069-1.04, Vernon's Texas Civil Statutes, as
     amended, to the extent, if any, applicable to any Lender or Co-Agent,
     each Borrower agrees that the Highest Lawful Rate for any Lender or
     Co-Agent shall be the "indicated (weekly) rate ceiling" as defined in
     said Article, provided that such Lender or Co-Agent may also rely, to
     the extent permitted by applicable laws, on alternative maximum rates
     of interest under other laws applicable to such Lender or Co-Agent if
     greater.  To the extent that Texas law shall be applicable to the
     determination of the Highest Lawful Rate of any Lender or Co-Agent,
     the provisions of Chapter 15 of Subtitle 3, Title 79 of the Revised
     Civil Statutes of Texas, 1925, as amended, shall not apply to this
     Agreement, the Notes or any other Loan Document.

No failure or delay on the part of the Administrative Agent, any Lender or the
holder of any Note in exercising any power or right under this Agreement or any
other Loan Document shall operate as a waiver thereof, nor shall any single or
partial exercise of any such power or right preclude any other or further
exercise thereof or the exercise of any other power or right.  No notice to or
demand on either Borrower in any case shall entitle it to any notice or demand
in similar or other circumstances.  No 

                                     -107-

respective officers, directors, employees and agents (collectively, the
"INDEMNIFIED PARTIES") free and harmless from and against any and all actions,
causes of action, suits, losses, costs, liabilities and damages, and expenses
incurred in connection therewith (irrespective of whether any such Indemnified
Party is a party to the action for which indemnification hereunder is sought),
including reasonable attorneys' fees, charges and disbursements (including
allocated costs of internal counsel) (collectively, the "INDEMNIFIED
LIABILITIES"), incurred by the Indemnified Parties or any of them as a result
of, or arising out of, or relating to

          (a) any transaction financed or to be financed in whole or in part,
     directly or indirectly, with the proceeds of any Loan or the use of any
     Letter of Credit;

          (b) the entering into and performance of this Agreement and any other
     Loan Document by any of the Indemnified Parties (including any action

     determination by the Majority Lenders pursuant to ARTICLE VI not to make
     any Credit Extension);

          (c) any investigation, litigation or proceeding related to any
     acquisition or proposed acquisition by either Borrower or any of its
     Subsidiaries of all or any portion of the stock or assets of any Person,
     whether or not the Administrative Agent or such Lender is party thereto;

          (d) any pending or threatened investigation, litigation or proceeding,
     or any action taken by any Person, 

                                     -109-
<PAGE>

     with respect to any Environmental Claim arising out of or related to the 
     Release by either Borrower or any of its Subsidiaries of any Hazardous 
     Material on any property owned, leased, occupied or used by such 
     Borrower or its Subsidiaries subject to any Collateral Document;

          (e) the presence on or under, or the escape, seepage, leakage,
     spillage, discharge, emission, discharging or releases from, any real
     property owned or operated by either Borrower or any Subsidiary thereof of
     any Hazardous Material (including any losses, liabilities, damages,
     injuries, costs, expenses or claims asserted or arising under any
     Environmental Law), regardless of whether caused by, or within the control
     of, such Borrower or such Subsidiary; or

          (f)  any Asbestos Litigation,

except for any such Indemnified Liabilities arising for the account of a
particular Indemnified Party by reason of the relevant Indemnified Party's gross
negligence or wilful misconduct.  No action taken by legal counsel chosen by the
Administrative Agent the Documentation Agent or any Lender in defending against
any such investigation, litigation or proceeding or requested remedial, removal
or response action shall vitiate or in any way impair the Revolving Borrower's
obligation and duty hereunder to indemnify and hold harmless the Administrative
Agent, the Documentation Agent and each Lender.  In no event shall any site
visit, observation, or testing by the Administrative Agent, the Documentation
Agent or any Lender be deemed a representation or warranty that Hazardous
Materials are or are not present in, on, or under the site, or that there has
been or shall be compliance with any Environmental Law.  Neither Borrower nor
any other Person is entitled to rely on any site visit, observation, or testing
by either Co-Agent or any Lender.  Neither the Administrative Agent nor any
Lender owes any duty of care to protect either Borrower or any other Person
against, or to inform either Borrower or any other party of, any Hazardous
Materials or any other adverse condition affecting any site or Property.
Neither the Administrative Agent, the Documentation Agent nor any Lender shall
be obligated to disclose to either Borrower or any other Person any report or
findings made as a result of, or in connection with, any site visit,
observation, or testing by either Co-Agent or any Lender.  If and to the extent
that the foregoing undertaking may be unenforceable for any reason, the
Revolving Borrower hereby agrees to make the maximum contribution to the payment
and satisfaction of each of the Indemnified Liabilities which is permissible
under applicable law.

     SECTION 11.5  SURVIVAL.  The obligations of each Borrower under SECTIONS
5.3, 5.4, 5.5, 5.6, 5.11, 11.3 and 11.4, and the obligations of the Lenders
under SECTION 10.1, shall in each case 

                                     -110-

<PAGE>

survive any termination of this Agreement, the payment in full of all 
Obligations and the termination of all Commitments.  The representations and 
warranties made by each Obligor in this Agreement and in each other Loan 
Document shall survive the execution and delivery of this Agreement and each 
such other Loan Document.

     SECTION 11.6  SEVERABILITY.  Any provision of this Agreement or any other
Loan Document which is prohibited or unenforceable in any jurisdiction shall, as
to such provision and such jurisdiction, be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining provisions of
this Agreement or such Loan Document or affecting the validity or enforceability
of such provision in any other jurisdiction.

     SECTION 11.7  HEADINGS.  The various headings of this Agreement and of each
other Loan Document are inserted for convenience only and shall not affect the

constitute together but one and the same agreement.

     SECTION 11.9  GOVERNING LAW; ENTIRE AGREEMENT.  THIS AGREEMENT, THE NOTES
AND EACH OTHER LOAN DOCUMENT SHALL EACH BE DEEMED TO BE A CONTRACT MADE UNDER

FEDERAL LAW.  This Agreement, the Notes and the other Loan Documents constitute
the entire understanding among the parties hereto with respect to the subject
matter hereof, supersede any prior agreements, written or oral, with respect
thereto and may not be contradicted by evidence of prior, contemporaneous or
subsequent oral agreements of the parties.

     SECTION 11.10  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
successors and assigns; PROVIDED, HOWEVER, that:

          (a) no Borrower may assign or transfer its rights or obligations
     hereunder without the prior written consent of the Administrative Agent and
     all Lenders; and

          (b) the rights of sale, assignment and transfer of the Lenders are

          (a) with the written consents of each Borrower (except that no consent
     of either Borrower shall be required after the occurrence and during the
     continuance of a Default), the Administrative Agent, and any Issuer (which
     consents shall not be unreasonably delayed or withheld and which consent,
     in the case of each Borrower, shall be deemed to have been given in the
     absence of a written notice delivered by each Borrower to the
     Administrative Agent, on or before the fifth Business Day after receipt by
     such Borrower of such Lender's request for consent, stating, in reasonable
     detail, the reasons why such Borrower proposes to withhold such consent)
     may at any time assign and delegate to one or more commercial banks or
     other financial institutions, and

          (b) with notice to either Borrower and the Administrative Agent, but
     without the consent of either Borrower or the Administrative Agent, may
     assign and delegate to any of its Affiliates or to any other Lender

(each Person described in either of the foregoing clauses as being the Person to
whom such assignment and delegation is to be made, being hereinafter referred to
as an "ASSIGNEE LENDER"), (x) all or any fraction of such Lender's total Loans
and Commitments, or (y) in the case of the Swingline Lender, all of its
Swingline Loans and Swingline Commitment (which assignment and delegation shall
be of a constant, and not a varying, percentage of all the assigning Lender's
Loans (other than Bid Loans) and Commitments and, in connection with any
assignment by BofA, its Swingline Commitment and Swingline Loans may be in whole
but not in part included as part of the assignment transaction) in a minimum
aggregate amount of $10,000,000; PROVIDED, HOWEVER, that any such Assignee
Lender will comply, if applicable, with the provisions contained in SECTION 5.12
and in the last sentence of SECTION 5.6 and FURTHER, PROVIDED, HOWEVER, that,
each Borrower, each other Obligor and the Administrative Agent shall be entitled
to continue to deal solely and directly with such Lender in connection with the
interests so assigned and delegated to an Assignee Lender until

          (c) written notice of such assignment and delegation, together with
     payment instructions, addresses and related information with respect to
     such Assignee Lender, shall have been given to each Borrower, the
     Administrative Agent and any Issuer by such Lender and such Assignee
     Lender,

                                     -112-
<PAGE>

          (d) such Assignee Lender shall have executed and delivered to each
     Borrower, the Administrative Agent and any Issuer a Lender Assignment
     Agreement, accepted by the Administrative Agent, and

          (e) the processing fees described below shall have been paid.

     From and after the date that the Administrative Agent accepts such Lender
Assignment Agreement, (x) the Assignee Lender thereunder shall be deemed
automatically to have become a party hereto and to the extent that rights and
obligations hereunder have been assigned and delegated to such Assignee Lender
in connection with such Lender Assignment Agreement, shall have the rights and
obligations of a Lender hereunder and under the other Loan Documents, and (y)
the assignor Lender, to the extent that rights and obligations hereunder have
been assigned and delegated by it in connection with such Lender Assignment
Agreement, shall be released from its obligations hereunder and under the other
Loan Documents.  If requested as provided in SECTION 2.9, within five Business
Days after its receipt of notice that the Administrative Agent has received an
executed Lender Assignment Agreement, each Borrower shall execute and deliver to
the Administrative Agent (for delivery to the relevant Assignee Lender) new
Notes evidencing such Assignee Lender's assigned Loans and Commitment or
Swingline Commitment, as the case may be, and, if the assignor Lender has
retained Loans and a portion of its Commitment hereunder, replacement Notes in
the principal amounts of the Loans and Commitment retained by the assignor
Lender hereunder (such Notes to be in exchange for, but not in payment of, the
Notes then held by such assignor Lender).  Each such Note shall be dated the
date of the predecessor Note.  Following receipt of the replacement Notes and
new Notes by the Assigning Lender and the Assignee Lenders, the assignor Lender
shall mark the predecessor Notes "exchanged" and deliver them to the applicable
Borrowers.  Accrued interest on that part of the predecessor Notes evidenced by
the Notes, and accrued fees, shall be paid as provided in the Lender Assignment
Agreement.  Accrued interest on that part of the predecessor Notes evidenced by
replacement Notes shall be paid to the assignor Lender.  Accrued interest and
accrued fees shall be paid at the same time or times provided in the predecessor
Notes and in this Agreement.  Such assignor Lender or such Assignee Lender must
also pay a processing fee to the Administrative Agent upon delivery of any
Lender Assignment Agreement in the amount of $3,500.

     SECTION 11.11.2  PARTICIPATIONS.  Any Lender may at any time sell to one or
more commercial banks or other Persons (each of such commercial banks and other
Persons being herein called a "PARTICIPANT") participating interests (or a
sub-participating interest, in the case of a Lender's participating interest in
a Letter of Credit) in any of the Loans (including its Bid Loans), 

                                     -113-

Commitment, or other interests of such Lender hereunder; PROVIDED, HOWEVER, 
that

          (a) no participation or sub-participation contemplated in this
     SECTION 11.11 shall relieve such Lender from its Commitment or Swingline
     Commitment, as the case may be, or its other obligations hereunder or under
     any other Loan Document,

          (b) such Lender shall remain solely responsible for the performance of
     its Commitment and such other obligations,

          (c) each Borrower and each other Obligor and the Administrative Agent
     shall continue to deal solely and directly with such Lender in connection
     with such Lender's rights and obligations under this Agreement and each of
     the other Loan Documents,

          (d) no Participant, unless such Participant is an Affiliate of such
     Lender, or is itself a Lender, shall be entitled to require such Lender to
     take or refrain from taking any action hereunder or under any other Loan
     Document, except that such Lender may agree with any Participant that such
     Lender will not, without such Participant's consent, take any actions of
     the type described in CLAUSE (b) or (c) of SECTION 11.1, and

          (e) neither Borrower shall be required to pay any amount under SECTION
     5.6 that is greater than the amount which it would have been required to
     pay had no participating interest been sold.

Each Borrower acknowledges and agrees that each Participant, for purposes of
SECTIONS 5.3, 5.4, 5.5, 5.6, 5.8, 5.9, 11.3 and 11.4, shall be considered a
Lender.

     SECTION 11.12  OTHER TRANSACTIONS.  Nothing contained herein shall preclude
the Administrative Agent or any other Lender from engaging in any transaction,
in addition to those contemplated by this Agreement or any other Loan Document,
with either Borrower or any of its Affiliates in which such Borrower or such
Affiliate is not restricted hereby from engaging with any other Person.

     SECTION 11.13  FORUM SELECTION AND CONSENT TO JURISDICTION.

     (a)  ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN
CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF

ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS
(WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN
AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, SUCH
BORROWER HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS
UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

     SECTION 11.14  WAIVER OF JURY TRIAL.

     THE ADMINISTRATIVE AGENT, THE LENDERS AND EACH BORROWER HEREBY KNOWINGLY,
VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY
IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN

     The Administrative Agent and each Lender agrees to take normal and

provided to it by such Borrower or any of its Subsidiaries, or by the
Administrative Agent on such Borrower's or Subsidiary's behalf, under this

shall use any such information other than in connection with or in enforcement
of this Agreement and the other Loan Documents; except to the extent such
information (i) was or becomes generally available to the public other than as a
result of disclosure by the Administrative Agent or any Lender, or (ii) was or
becomes available on a non-confidential basis from a source other than such
Borrower, PROVIDED that such source is not bound by a confidentiality agreement
with such Borrower known to the Administrative Agent or such Lender, as the case
may be; PROVIDED, HOWEVER, that the Administrative Agent or any Lender may
disclose such information (A) at the request or pursuant to any requirement of
any Governmental Authority to which the Administrative Agent or Lender is

     President/Treasurer of Stone and the Vice President of the Term Borrower;

capacity of natural persons, the authenticity of the documents submitted to 
us as originals, the conformity to the original documents of all documents 
submitted to us as certified, facsimile or photostatic copies, and the 
authenticity of the originals of such copies. As to any facts material to the 
opinions hereinafter expressed which we did not independently establish or 
verify, we have relied without investigation upon certificates, statements 
and representations of representatives of the Companies. Regarding documents 
executed by parties other than the U.S. Companies, we have assumed (i) that 
each such other party had the power to enter into and perform all its 
obligations thereunder, and (ii) the due authorization, execution and 
delivery of such documents by each such party. Regarding documents executed 
by parties other than the Companies, we have assumed that such documents 
constitute the legal, valid and binding obligations of each such party.

     We refer you to the opinion referred to above given by Messrs. Fraser &
Beatty, containing certain opinions concerning the Term Borrower.

     With respect to our opinion in paragraph 1 below as to the good standing of
the U.S Companies in any jurisdictions other than Delaware and California, we
are relying solely on the representations of the U.S. Companies set forth in the
Officer's Certificate and the status searches obtained by us, without further
investigation as to the criteria for qualification or any related legal issues
with respect to such jurisdictions.

     Based upon and subject to the foregoing, and subject to the further
assumptions, limitations, qualifications and exceptions set forth herein, we are
of the opinion that:

     1.   The Revolving Borrower and Pabco each (i) (A) is a corporation duly
incorporated, validly existing and in good standing under the laws of the State
of Delaware (B) with the corporate power and authority to own its properties and
to carry on its business as, to our knowledge, it is now conducted, and (ii) is
qualified as a foreign corporation and in good standing under the laws of the
State of California. Norandex and Vytec Sales each (a) is a corporation duly
incorporated, validly existing and in good standing under the laws of the State
of Delaware (b) with the corporate power and authority to own its properties and
to carry on its business as, to our knowledge, it is now conducted. Stone (1) is
a corporation duly incorporated, validly existing and in good standing under the
laws of the State of California (2) with the corporate power and authority to
own its properties and to carry on its business as, to our knowledge, it is now
conducted. Each of the Revolving Borrower, Pabco, Norandex and Vytec Sales is
qualified as a foreign corporation and in good standing under the laws of the
State of Texas.

     2.   Each U.S. Company has the corporate power and authority to enter into
and perform the Company Documents to which it is a party, and has taken all

March 28, 1997                                                         Page 4


necessary corporate action to authorize the execution, delivery and performance
of the Company Documents to which it is a party.

     3.   No consents, approvals or authorizations of, or notices to or filings
with, any governmental authority or agency under the laws of the State of
California or the laws of the United States, as presently in effect and
interpreted, are required or necessary on the part of the Companies in
connection with the execution and delivery by the Companies of the Company
Documents.

     4.   Each Company Document to which the Revolving Borrower is a party
constitutes the legal, valid and binding obligation of the Revolving Borrower,
enforceable against the Revolving Borrower in accordance with its terms.

     5.   The Guaranty of each Guarantor constitutes the legal, valid and
binding obligation of such Guarantor, enforceable against such Guarantor in
accordance with its terms.

     6.   Each Company Document to which the Term Borrower is a party
constitutes the legal, valid and binding obligation of the Term Borrower,
enforceable against the Term Borrower in accordance with its terms.

     7.   The execution, delivery or performance by each U.S. Company of the
Company Documents to which it is a party do not and will not (i) violate or be
in conflict with any provision of the Certificate of Incorporation or Bylaws of
such U.S. Company, or (ii) violate or conflict with or constitute a default
under or result in the termination of, accelerate the performance required by,
or result in the creation of any lien, security interest, charge or encumbrance
upon any of the assets or properties of any U.S. Company under, any term or
provision of any of the Material Agreements. The execution, delivery or
performance by each Company of the Company Documents to which it is a party do
not and will not (A) violate or be in conflict with any federal or California
law having applicability to such Company, as presently in effect and
interpreted, or (B) to our knowledge, violate or contravene any judgment,
decree, injunction or order of any federal or California court, or any
arbitrator or governmental agency or authority, having jurisdiction over such
Company or its properties or by which such Company may be bound.

     8.   We have no knowledge of any pending litigation or other proceedings
against the Revolving Borrower or its properties before any court, arbitrator or
governmental agency or authority which challenge the validity or enforceability
of the Company Documents or, except for those matters disclosed in Item 7.7 of
the Disclosure Schedule, which, if determined adversely to the Revolving
Borrower, would be likely to have a material adverse effect on the Revolving
Borrower.

     Whenever a statement herein is qualified by the expressions "known to us,"
"to our knowledge," "we are not aware" or a similar phrase with respect to our
knowledge of matters of fact, it is intended to mean that our knowledge is based
upon the records, documents, instruments and certificates described above and
the current actual knowledge of the attorneys in this Firm who have devoted
substantive attention to the transactions contemplated by the Company Documents
or, with respect to the opinion expressed in paragraph 8 above, who are
presently involved in substantive legal representation of the Revolving Borrower
(but not including any constructive or imputed notice of any information) and
that we have not otherwise undertaken any independent investigations for the
purpose of rendering this opinion.

     This opinion is limited to the laws of the State of California, the General
Corporation Law of the State of Delaware and applicable federal laws of the
United States, and we express no opinion herein with respect to the effect or
applicability of the laws of other jurisdictions.

     Our opinions in paragraph 3 above and in clause (B) of paragraph 7 above
are limited to laws and regulations normally applicable to transactions of the
type contemplated in the Company Documents and do not extend to licenses,
permits and approvals necessary for the conduct of any Company's business. In
addition and without limiting the previous sentence, we express no opinion
herein with respect to the effect of any land use, environmental or similar law,
any state or federal antitrust law, state or federal securities laws, or any
local law.

     The opinions set forth above are subject to the following qualifications,
assumptions, limitations and exceptions:

     (a)  The validity, binding nature and enforce ability of each Company's
obligations under the Company Documents are subject to the effect of (i)
bankruptcy, insolvency, reorganization, arrangement, moratorium, fraudulent
transfer and other similar laws affecting the rights of creditors generally;
(ii) the discretion of any court of competent jurisdiction in awarding equitable
remedies, including, without limitation, specific performance or injunctive
relief, and the effect of general principles of equity embodied in California
statutes and common law; and (iii) the effect of California court decisions and
statutes which indicate that provisions of the Company Documents which permit
any Co-Agent, any of the Lenders or any other Person to take action or make
determinations may be subject to a requirement that such action be taken or such
determinations be made on a reasonable basis in good faith or that it be shown
that such action is reasonably necessary for the protection of such Co-Agent,
such Lender or such other Person.

     (b)  We express no opinion as to:

March 28, 1997                                                         Page 6

          (1)    the enforceability of provisions of the Company Documents
pursuant to which any Company agrees to make payments without set-off, defense
or counterclaim;

          (2)    provisions purporting to require the award or payment of
attorneys' fees, expenses or costs in any action where any Lender or Co-Agent is
not the prevailing party, or the impact of California Civil Code ("CC") Section
1717 ET SEQ. on any such provisions;

          (3)    under certain circumstances, provisions to the effect that
rights or remedies are not exclusive, that every right or remedy is cumulative
and may be exercised in addition to or with any other right or remedy, that the
election of some particular remedy or remedies does not preclude recourse to one
or another remedy or that failure to exercise or delay in exercising rights or
remedies will not operate as a waiver of any such right or remedy;

          (4)    provisions prohibiting waivers of any terms or provisions of
any of the Company Documents other than in writing, or prohibiting oral
modifications thereof or modification by course of dealing to the extent such
provisions are inconsistent with applicable law;

          (5)    the enforceability under certain circumstances of provisions
indemnifying a party against, or requiring contributions toward, that party's
liability for its own wrongful or negligent acts or where such indemnification
or contribution is contrary to public policy or prohibited by law;

          (6)    any provision providing for the exclusive jurisdiction of a
particular court or purporting to waive rights to trial by jury, service of
process or objections to the laying of venue or to forum on the basis of forum
NON CONVENIENS, in connection with any litigation arising out of or pertaining
to the Company Documents;

          (7)    provisions providing for an increase in the rate of interest or
imposing a late charge or penalty in the event of delinquency or default;

          (8)    provisions imposing a prepayment charge, fee or penalty based
upon a percentage or fraction of the amount prepaid or the amount outstanding
under the Amended Credit Agreement, except in the case of a voluntary prepayment
by the Revolving Borrower or the Term Borrower;

          (9)    provisions purporting to waive statutory or common law rights,
including the right to receive notice or to be allowed to cure, reinstate or
redeem in the event of default, and provisions expressly or by implication
waiving broadly or vaguely stated rights, unknown future rights and defenses to
obligations, in each case to

March 28, 1997                                                         Page 7

the extent such rights or defenses are not waivable under applicable law and, 
without limiting the generality of the foregoing, Sections 2.3 and 5.2 of 
each Guaranty, to the extent of the possible ineffectiveness under applicable 
law of any of the consents and waivers therein;

          (10)   provisions purporting to designate the Administrative Agent as
any Company's agent or attorney in fact;

          (11)   provisions purporting to waive any applicable statutes of
limitation;

          (12)   provisions authorizing any Lender to set off and apply any
deposits at any time held, and any other indebtedness at any time owing, by such
Lender to or for the account of any Company; and

          (13)   Section 10.14 of the Amended Credit Agreement.

     (c)  Our opinions are subject to the effect of judicial decisions which may
permit the introduction of extrinsic evidence to interpret the terms of written
contracts.

     (d)  Insofar as this opinion letter concerns the law of the State of
California limiting the rates of interest legally chargeable or collectible, we
have relied upon our understanding that each of the Lenders is (i) a subsidiary
of a bank holding company or is a bank organized under the laws of the United
States or any State thereof or (ii) a foreign (other nation) bank within the
meaning of Section 1716 of the California Financial Code, and such Lender (A)
has assets equal to at least $100,000,000, (B) is licensed to maintain an office
in California, (C) is licensed or otherwise authorized by another state of the
United States to maintain an agency or branch in such state, or (D) maintains a
Federal agency or Federal branch in any state of the United States and, as a
result thereof, is exempt from the restrictions of Section 1 of Article XV of
the Constitution of the State of California relating to rates of interest upon
the loan of money. We further assume in this regard that all Loans have been and
will be made by the Lenders for their own account and without intent to
circumvent otherwise applicable interest rate limitations under California law
and that there is no present express or implied agreement or plan to sell
participations or any other interest in the Loans or the Amended Credit
Agreement to any Person other than a Person that also qualifies for an exemption
from the interest rate limitations of California law.

     (e)  We wish to point out that the Lenders who are holders of Notes may be
required to prove the outstanding amount thereof.

     (f)  We have assumed that each Lender has complied with any applicable
requirements to file returns or pay California taxes as required by California
Revenue and Taxation Code Section 23301 ET SEQ.

     The opinions expressed herein are solely for your benefit in connection
with the above transactions and may not be relied on in any manner or for any

The Lenders party to the Amended
Credit Agreement referred to below,
Bank of America National Trust and
Savings Association, as Administrative
Co-Agent, and NationsBank, N.A.
as Documentation Co-Agent

Ladies and Gentlemen:

                            RE: VYTEC CORPORATION

     This opinion letter is furnished to you pursuant to Section 6.1.5 of the
Fourth Amended and Restated Credit Agreement dated as of March 28, 1997 (the
"Amended Credit Agreement"), among Fibreboard Corporation, Vytec Corporation
(the "Term Borrower"), the various financial institutions which are parties
thereto (collectively, the "Lenders"), Bank of America National Trust and
Savings Association, as Administrative Co-Agent for such Lenders (the
"Administrative Agent"), and Nationsbank, N.A., as Documentation Co-Agent for
such Lenders (the "Documentation Agent"; each of the Administrative Agent and
the Documentation Agent sometimes hereinafter referred to in this opinion
individually as a "Co-Agent" and together as "Co-Agents").  Unless otherwise
defined herein, terms used herein shall have the meanings assigned to them in
the Amended Credit Agreement.  We have acted as special counsel for the Term
Borrower in connection with the Amended Credit Agreement.

     In connection with this opinion letter, we have examined and relied on
originals, telecopies or copies certified or otherwise identified to our
satisfaction, of such documents, corporate records, certificates (including
certificates of public officials) and other instruments as we have deemed
necessary or advisable for purposes of this opinion letter, including those
relating to the authorization, execution and delivery by the Term Borrower of
the Amended Credit Agreement, and including the following documents (the items
referred to in subclauses (i) and (ii) below herein referred to as the "Company
Documents"):


<PAGE>

                                                                            2.
                              FRASER & BEATTY


          (i)    a telecopy of an executed copy of the Amended Credit Agreement;

          (ii)   a telecopy of the amended and restated master promissory notes
                 (term loans) executed by the Term Borrower in favour of various
                 of the Lenders;

         (iii)   the Articles of Amalgamation and the Bylaws of the Term
                 Borrower, each as in effect on the date hereof;

          (iv)   a telecopy of an executed copy of the certificate of the
                 Secretary of the Term Borrower dated the date hereof certifying
                 INTER ALIA: (A) true copies of the resolutions of the Board of
                 Directors of the Term Borrower authorizing, among other things,
                 the execution, delivery and performance of the Company
                 Documents, and (B) the incumbency, authority and true
                 signatures of the officers of the Term Borrower authorized to
                 sign the Company Documents and any other documents and
                 certificates delivered in connection therewith;

          (v)    a telecopy of an executed copy of the certificate (the
                 "Officer's Certificate") of the Vice-President of the Term
                 Borrower dated the date hereof; and

          (vi)   a certificate of status dated March 24, 1997 issued by the
                 Ministry of Consumer and Commercial Relations (Ontario) in
                 respect of the Term Borrower, upon which we have relied for the
                 purpose of rendering the opinion in paragraph 1 below.

          We have also examined photostatic copies of the agreements identified
in EXHIBIT B to the Officer's Certificate (the "Material Agreements"). In our
examinations and reviews we have assumed the genuineness of all signatures, the
legal capacity of natural persons, the authenticity of the documents submitted
to us as originals, the conformity to the original documents of all documents
submitted to us as certified or photostatic copies or telecopies, the accuracy
of all certificates, and the authenticity of the originals of such copies. As to
any facts material to the opinions hereinafter expressed which we did not
independently establish or verify, we have relied without investigation upon
certificates, statements and representations of representatives of the Term
Borrower.  Regarding documents executed by parties other than the Term Borrower,
we have assumed (i) that each such other party had the power to enter into and
perform all its obligations thereunder, (ii) the due authorization of, and the
due execution and delivery 


<PAGE>

                                                                            3.
                              FRASER & BEATTY


of, such documents by each such party, and (iii) that such documents 
constitute the legal, valid and binding obligations of each such party.

          We are solicitors qualified to practise in the Province of Ontario
and, accordingly, the opinions expressed herein are restricted to the laws of
the Province of Ontario and the federal laws of Canada applicable therein. In
this opinion, "ONTARIO COURTS" means the courts of the Province of Ontario and
the federal courts constituted by the Parliament of Canada for the better
administration of the laws of Canada, the jurisdiction of which extends to
disputes arising in the Province of Ontario.

          Wherever any opinion set forth herein with respect to the existence or
absence of facts is qualified by the phrase "of which we are aware" or "to our
knowledge", it is intended to indicate that, during the course of our
representation of the Term Borrower, no information has come to the attention of
the lawyers in this firm who have devoted substantive attention to the
transactions contemplated by the Company Documents (being Ronald Marshall and
Douglas Scott) which has given us actual knowledge of, or caused us to believe
or suspect, the existence or absence of such facts. Except to the extent
expressly set forth herein, we have not undertaken any independent investigation
to determine the existence or absence of facts, and no inference as to our
knowledge of the existence or absence of such facts should be drawn from the
fact of our representation of the Term Borrower.

          Based upon and subject to the foregoing, and subject to the further
assumptions, limitations, qualifications and exceptions set forth herein, we are
of the opinion that:

          1.     The Term Borrower is a subsisting corporation in good standing
under the laws of the Province of Ontario with the corporate power and authority
to own its properties and to carry on its business as, to our knowledge, it is
now conducted.

          2.     The Term Borrower has the corporate power and authority to
enter into and perform the Company Documents, and has taken all necessary
corporate action to authorize the execution, delivery and performance of the
Company Documents.

          3.     No consents, approvals or authorizations of, or notices to or
filings with, any governmental authority or agency under the laws of Canada or
the laws of the Province of Ontario, as presently in effect and interpreted, are
required or necessary on the part of the Term Borrower in 


<PAGE>

                                                                            4.
                              FRASER & BEATTY


connection with the execution and delivery by the Term Borrower of the 
Company Documents; provided that in respect of any contract or agreement 
between the Term Borrower and any such authority or agency, the foregoing 
applies to our knowledge.

          4.     The execution, delivery or performance by the Term Borrower of
the Company Documents do not and will not (i) violate or be in conflict with any
provision of the Articles of Amalgamation or Bylaws of the Term Borrower, (ii)
violate or be in conflict with any federal or Ontario law having applicability
to the Term Borrower, as presently in effect and interpreted, (iii) to our
knowledge, violate or contravene any judgment, decree, injunction or order of
any federal or Ontario court, or any arbitrator or governmental agency or
authority, having jurisdiction over the Term Borrower or its properties or by
which the Term Borrower may be bound, or (iv) violate or conflict with or
constitute a default under or result in the termination of, accelerate the
performance required by, or result in the creation of any lien, security
interest, charge or encumbrance upon any of the assets or properties of the Term
Borrower under, any term or provision of the Material Agreements.

          5.     To our knowledge there is no pending litigation or other
proceeding against the Term Borrower or its properties before any court,
arbitrator or governmental agency or authority which challenge the validity or
enforceability of the Company Documents or which, if determined adversely to the
Term Borrower, would be likely to have a material adverse effect on the Term
Borrower.

          6.     The choice of the parties of the laws of the State of
California to govern the Company Documents will, to the extent specifically
pleaded and proved as a fact by expert evidence, be recognized and given effect
to by the Ontario Courts, provided that:

          (a)    The choice of law was freely made by the parties thereto;

          (b)    the parties have not chosen the laws of the State of California
                 for the purpose of evading the provisions of the system of law
                 to which the transactions contemplated by the Company Documents
                 are most closely related;

          (c)    the choice of law will only be effective in regard to
                 substantive law, and the procedural laws of the jurisdiction in
                 which the substantive rights are being enforced will apply;


<PAGE>

                                                                            5.
                              FRASER & BEATTY

          (d)    an Ontario Court will not apply those laws of the State of
                 California which it characterizes as being of a revenue,
                 expropriatory, penal or public nature; and

          (e)    enforcement of any provision of the Company Documents in the
                 Ontario Courts will not be contrary to public policy (as that
                 term is applied by the Ontario Courts) or a statute protecting
                 the citizens of Ontario.

          7.     Any final judgment for a definite sum given by any court in the
State of California (the "foreign court") against the Term Borrower in respect
of the Company Documents would, in an action to enforce such judgment in the
Ontario Courts, be recognized as conclusive and enforceable without
reconsideration of the merits of the action, provided that:

          (a)    such judgment was for a sum certain in money;

          (b)    such judgment was final, conclusive and enforceable where
                 rendered and does not conflict with another final and
                 conclusive judgment on the same cause of action;

          (c)    such judgment was not obtained by fraud or in a manner contrary
                 to natural justice;

          (d)    the foreign court rendering the judgment was impartial and
                 provided procedures compatible with the due process and natural
                 justice standards of the Ontario Courts;

          (e)    the foreign court that rendered the judgment had jurisdiction
                 over the Term Borrower and the subject matter and, if
                 jurisdiction in the foreign court was based on personal service
                 alone, the foreign court was not a seriously inconvenient forum
                 for the trial of the action;

          (f)    the proceedings in the foreign court were not contrary to an
                 agreement between the parties under which the dispute in
                 question was to be settled otherwise than by proceedings in
                 that court;

          (g)    such judgment was a subsisting judgment and had not been
                 satisfied;

                              FRASER & BEATTY

          (h)    after the date of judgment in the foreign court, application to
                 the Ontario Courts to enforce such judgment had been made
                 within twenty (20) years;

          (i)    the claim for relief on which the foreign judgment was based
                 was not repugnant to the public policy of the Province of
                 Ontario, as that term is applied by the Ontario Courts; and

          (j)    any monetary judgment by the Ontario Courts relating to a
                 currency other than Canadian dollars will be expressed as the
                 amount in Canadian currency necessary to purchase the required
                 amount of such other currency.

          Re:  FIBREBOARD CORPORATION

Ladies/Gentlemen:

     This opinion is furnished to you pursuant to Section 6.1.5(c) of that
certain Fourth Amended and Restated Credit Agreement, dated as of March 28, 1997
(the "CREDIT AGREEMENT"), among Fibreboard Corporation, a Delaware corporation
(the "REVOLVING BORROWER"), Vytec Corporation, a corporation formed under the
laws of Ontario, Canada, (the "TERM BORROWER", and together with the Revolving
Borrower, the "BORROWERS"), certain lenders which are or may become parties
thereto (the "LENDERS"), Bank of America National Trust and Savings Association,
as administrative co-agent for the Lenders (in such capacity, the
"ADMINISTRATIVE AGENT") and Nationsbank N.A., as documentation co-agent for the
Lenders (in such capacity, the "DOCUMENTATION AGENT").  Unless otherwise defined
herein, capitalized terms used herein have the meanings provided in the Credit
Agreement.

     We have acted as counsel for the Administrative Agent in the preparation,
execution and delivery of the Credit Agreement.

     In connection with this opinion, we have examined an original, or copy
certified or otherwise identified to our satisfaction as being a true copy, of a
counterpart of the Credit

  The Administrative Agent, the Documentation

  Credit Agreement referred to below

Agreement executed by the Borrowers, the Administrative Agent, the 
Documentation Agent and the Lenders.

     In addition to the Credit Agreement, we have also reviewed the documents
and opinions of counsel listed on SCHEDULE I attached hereto and furnished
pursuant to the Sections of the Credit Agreement indicated on SCHEDULE I.

     For the purposes of this opinion, we have assumed that all items submitted
to us as originals are authentic and all signatures thereon are genuine, and
that all items submitted to us as copies conform to the originals.  We also have
assumed that (a) each Borrower duly executed and delivered the Credit Agreement
and all other documents to which such Borrower is a party pursuant to due
authorization, and (b) the Credit Agreement has been duly executed and delivered
by the Administrative Agent, the Documentation Agent and each Lender, pursuant
to due authorization as such party's legal, valid and binding obligation,
enforceable against such party in accordance with its terms (subject to the
effect of any applicable bankruptcy, insolvency, reorganization, moratorium or
similar law affecting creditors' rights generally and to the effect of general
principles of equity, including, without limitation, concepts of materiality,
reasonableness, good faith and fair dealing (regardless of whether considered in
a proceeding in equity or at law)).

     Based upon the foregoing, and subject to the matters stated herein, we are
of the opinion that, under the laws of the State of California:

     1.   The Credit Agreement constitutes a legal, valid and binding obligation
of each Borrower, enforceable in accordance with its terms.

     2.   The other documents listed on SCHEDULE I attached hereto are
substantially responsive to the requirements of the Credit Agreement.

     Our opinions set forth above are subject to the following qualifications:

  Agent and each of the Lenders

  Credit Agreement referred to below

     A.  Our opinions in paragraph 1 above are subject to the assumptions,
qualifications, exceptions and limitations set forth in the opinions of counsel
to the Borrowers furnished pursuant to clauses (a) and (b) of Section 6.1.5 of
the Credit Agreement.

     B.  In addition, we advise you that a California court may not strictly
enforce certain covenants contained in the Credit Agreement or allow
acceleration of the maturity of the indebtedness incurred under the Credit
Agreement if it concludes that such enforcement or acceleration would be
unreasonable under the then existing circumstances.  We do believe, however,
that subject to the limitations expressed elsewhere in this opinion (including,
without limitation, paragraph A above), enforcement or acceleration would be
available if an Event of Default occurs as a result of a material breach of a
material covenant contained in the Credit Agreement.

     C.  We express no opinion as to matters of creation or perfection of any
liens or security interests under the Collateral Documents, and we refer you to
the opinion of counsel listed as item 2 on SCHEDULE I attached hereto with
respect to such matters.

     D.  We express no opinion as to the effect of the law of any jurisdiction
other than the State of California wherein any Lender or any Lender's initial or
successor funding office may be located, or wherein enforcement of the Credit
Agreement or any Note may be sought, which limits the rates of interest legally
chargeable or collectible.

     We are members of the Bar of the State of California and for purposes of
this opinion do not purport to be experts on, or to express any opinions herein
concerning, any law other than the laws of the State of California.

     This opinion is furnished by us as counsel to the Administrative Agent to
you solely in connection with the transactions described above.  This opinion
may be relied upon by the Administrative Agent, the Documentation Agent, each
Lender, any assignee of any Lender, any participant in any Loan, and the

                            SOLVENCY CERTIFICATE OF
                 VYTEC CORPORATION AND FIBREBOARD CORPORATION

TO:       The parties to the Fourth Amended and Restated Credit Agreement, dated
          as of March 28, 1997, among Fibreboard Corporation (the "REVOLVING
          BORROWER"), Vytec Corporation, (the "TERM BORROWER"; together with the
          Revolving Borrower, the "BORROWERS" and each individually, a
          "BORROWER"), the various lenders which are or may become parties
          thereto (the "LENDERS"), Bank of America National Trust and Savings
          Association, as the administrative co-agent for the Lenders (in such
          capacity, the "ADMINISTRATIVE AGENT"), and Nationsbank N.A., as the
          documentation co-agent for such Lenders (in such capacity, the
          "DOCUMENTATION AGENT").


     This Certificate is delivered pursuant to Section 6.1.6 of the Fourth
Amended and Restated Credit Agreement, dated as of March 28, 1997, (as amended
or otherwise modified from time to time, the "CREDIT AGREEMENT"), among the
Revolving Borrower, the Term Borrower, the Lenders, the Administrative Agent and
the Documentation Agent.  Terms defined in the Credit Agreement are, unless
otherwise defined herein or the context otherwise requires, used herein as
defined in the Credit Agreement. Section references herein are to the Credit
Agreement.

     I hereby certify to the Administrative Agent, the Documentation Agent and
each Lender as follows:

     1.  I am the Vice President Finance of the Revolving Borrower and the Vice
President of the Term Borrower and, in such respective capacities, am the
principal accounting officer of the Revolving Borrower and the Term Borrower.

     2.   I have carefully reviewed the contents of this Certificate and
understand its meaning.

     3.  I have also participated in preparing the balance sheets and the
related statements of income, stockholders' equity and cash flows of the
Revolving Borrower described in Section 7.5 of the Credit Agreement and have
reviewed and am familiar with the balance sheets and the related statements of
income, stockholders' equity and cash flows of the Term Borrower described in
Section 7.5 of the Credit Agreement, each of which has been furnished to the
Administrative Agent, the Documentation

<PAGE>

Agent and each Lender for the purposes of or in connection with the Credit
Agreement.

     4.  In connection with the conclusions set forth below, I have made such
investigation and inquiries as I deem necessary and prudent therefor and
specifically have relied on historical information and other data supplied by
personnel directly responsible for the various operations involved.

     Based upon the foregoing, and subject to the uncertainty and approximation
inherent in any projection and forecast, I have reached the conclusion that,
after giving effect to the transactions contemplated to occur on the Restatement
Effective Date and on the date of each Credit Extension under the Credit
Agreement,

          (a)    the net worth of each Borrower and each Obligor determined in
     accordance with GAAP consistently applied will not be less than zero;

          (b)    the respective assets of each Borrower and each Obligor at fair
     valuation, will exceed its respective liabilities, including contingent
     liabilities;

          (c)    the respective capital of each Borrower and each Obligor will
     not be unreasonably small to conduct its respective business; and

          (d)    neither of the Borrowers nor any other Obligor will have
     incurred debts, or intends to incur debts, beyond its respective ability to
     pay such debts as they mature.

     For purposes of this Certificate, "debt" means any liability with respect
to (a) a right to payment, whether or not such right is reduced to judgment,
liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed,
undisputed, legal, equitable, secured or unsecured, or (b) a right to an
equitable remedy for breach of performance if such breach gives rise to a
payment, whether or not such right to an equitable remedy is reduced to
judgment, fixed, contingent, matured, unmatured, disputed, undisputed, secured
or unsecured.

     I understand you are relying on the truth and accuracy of the foregoing in
connection with your entering into the Credit Agreement and making Loans and
issuing and participating in Letters of Credit thereunder and that no one else
shall be entitled to rely on this Certificate other than your permitted
successors and assigns.

                                     -2-

     I represent the foregoing information to be, in good faith and to the best
of my knowledge, true and accurate, and execute this Certificate as Vice
President Finance of the Revolving Borrower and Vice President of the Term
Borrower (and, in each case, solely in may capacity as such) and as of this 28th
day of March, 1997.

                                    GUARANTY

     THIS GUARANTY (this "GUARANTY"), dated as of March 28, 1997, jointly and
severally made by each of the corporations set forth under the caption
"GUARANTORS" on the signature pages hereto (each a "GUARANTOR"), in favor of
each Lender Party (as defined below).

     A.  Pursuant to a Fourth Amended and Restated Credit Agreement, dated as of

and Savings Association, as the administrative co-agent for such Lenders
(together with any successor(s) thereto in such capacity, the "ADMINISTRATIVE
AGENT"), and Nationsbank N.A., as the documentation co-agent for such Lenders

Revolving Borrower and to participate in Letters of Credit issued by an Issuer
for the account of the Revolving Borrower.

     C.   Each Guarantor has duly authorized the execution, delivery and
performance by it of this Guaranty.

hereby acknowledged, and in order to induce (i) the Lenders to make Loans

                             GUARANTY PROVISIONS

     SECTION 2.1.  GUARANTY.  Each Guarantor hereby jointly and severally
absolutely, unconditionally and irrevocably

          (a)    guarantees the full and punctual payment when due, whether at
     stated maturity, by required prepayment, declaration, acceleration, demand
     or otherwise, of all Obligations of each Borrower and each other Obligor
     now or hereafter existing under the Credit Agreement, the Notes and each
     other Loan Document to which either Borrower or such other Obligor is or
     may become a party, whether for principal, interest, fees, expenses or
     otherwise (including all such amounts which would become due but for the
     operation of the automatic stay under Section 362(a) of the United States
     Bankruptcy Code, 11 U.S.C. Section 362(a), and the operation of Sections
     502(b) and 506(b) of the United States Bankruptcy Code, 11 U.S.C. Section
     502(b) and Section 506(b)), and

          (b)    indemnifies and holds harmless each Lender Party and each
     holder of a Note for any and all reasonable costs and expenses (including
     reasonable attorney's fees and expenses) incurred by such Lender Party or
     such holder, as the case may be, in enforcing any rights under this
     Guaranty;

PROVIDED, HOWEVER, that each Guarantor shall be jointly and severally liable
under this Guaranty for the maximum amount of such liability that can be hereby
incurred by such Guarantor without rendering this Guaranty, as it relates to
such Guarantor, void or voidable under Applicable Law relating to fraudulent
conveyance or fraudulent transfer, and not for any greater amount.  This
Guaranty constitutes a guaranty of payment when due and not of collection, and
each Guarantor specifically agrees that it shall not be necessary or required
that any Lender Party or any holder of any Note exercise any right, assert any
claim or demand or enforce any remedy whatsoever against either Borrower or any
other Obligor (or any other Person) before or as a condition to the obligations
of such Guarantor hereunder.

     SECTION 2.2.  ACCELERATION OF GUARANTY.  Each Guarantor agrees that, in the
event of the dissolution or insolvency of either Borrower, or any other Obligor
or such Guarantor, or the inability or failure of either Borrower, any other
Obligor or such Guarantor to pay debts as they become due (subject to any
applicable grace periods), or an assignment by either Borrower, any other
Obligor or such Guarantor for the benefit of creditors, or the commencement of
any case or proceeding in respect of either Borrower, any other Obligor or such
Guarantor under any

                                     3
<PAGE>

bankruptcy, insolvency or similar laws, and if such event shall occur at a
time when any of the Obligations of each Borrower and each other Obligor may
not then be due and payable, such Guarantor will pay to the Lenders forthwith
the full amount which would be payable hereunder by such Guarantor if all such
Obligations were then due and payable.

     SECTION 2.3.  GUARANTY ABSOLUTE, ETC.  This Guaranty shall in all respects
be a continuing, absolute, unconditional and irrevocable guaranty of payment,
and shall remain in full force and effect until all Obligations of the Borrowers
and each other Obligor have been paid in full, all obligations of each Guarantor
hereunder shall have been paid in full and all Commitments shall have terminated
and all Letters of Credit have expired or been terminated.  Each Guarantor
jointly and severally guarantees that the Obligations of the Borrowers and each
other Obligor will be paid strictly in accordance with the terms of the Credit
Agreement and each other Loan Document under which they arise, regardless of any
law, regulation or order now or hereafter in effect in any jurisdiction
affecting any of such terms or the rights of any Lender Party or any holder of
any Note with respect thereto.  The joint and several liability of each
Guarantor under this Guaranty shall be absolute, unconditional and irrevocable
irrespective of, and each Guarantor hereby waives any defense arising out of or
related to:

          (a)    any lack of validity, legality or enforceability of the Credit
     Agreement, any Note or any other Loan Document;

          (b)    all statutes of limitations asserted as a defense to any action
     brought by the Administrative Agent or any other Lender Party against any
     Guarantor;

          (c)    any disability or any other defense of the either Borrower or
     any other Person with respect to the Obligations, whether consensual or
     arising by operation of law or any bankruptcy, insolvency or debtor-relief
     proceeding, or from any other cause;

          (d)    the failure of the Administrative Agent or any other Lender
     Party or any holder of any Note

                 (i)     to assert any claim or demand or to enforce any right
          or remedy against either Borrower, any other Obligor or any other
          Person (including any other guarantor) under the provisions of the
          Credit Agreement, any Note, any other Loan Document or otherwise, or

                                     4
<PAGE>

                 (ii)    to exercise any right or remedy against any other
          guarantor of, or collateral securing, any Obligations of the either
          Borrower or any other Obligor;

          (e)    any change in the time, manner or place of payment of, or in
     any other term of, all or any of the Obligations of either Borrower or any
     other Obligor, or any other extension, compromise or renewal of any
     Obligation of either Borrower or any other Obligor;

          (f)    any reduction, limitation, impairment or termination of any
     Obligations of the either Borrower or any other Obligor for any reason,
     including any claim of waiver, release, surrender, alteration or
     compromise, and shall not be subject to (and each Guarantor hereby waives
     any right to or claim of) any defense or setoff, counterclaim, recoupment
     or termination whatsoever by reason of the invalidity, illegality,
     nongenuineness, irregularity, compromise, unenforceability of, or any other
     event or occurrence affecting, any Obligations of either Borrower, any
     other Obligor or otherwise;

          (g)    any amendment to, rescission, waiver, or other modification of,
     or any consent to departure from, any of the terms of the Credit Agreement,
     any Note or any other Loan Document;

          (h)    any addition, exchange, release, surrender or non-perfection of
     any collateral, or any amendment to or waiver or release or addition of, or
     consent to departure from, any other guaranty, held by the Administrative
     Agent or any other Lender Party or any holder of any Note securing any of
     the Obligations of either Borrower or any other Obligor;

          (i)    all suretyship defenses and rights of every nature otherwise
     available under California law and the laws of any other jurisdiction,
     including without limitation all defenses arising under Sections 2787
     through 2855, and Sections 2899 and 3433 of the California Civil Code and
     any successor provisions of those Sections; and

          (j)    any other circumstance which might otherwise constitute a
     defense available to, or a legal or equitable discharge of, either
     Borrower, any other Obligor, any surety or any guarantor.

     SECTION 2.4.  REINSTATEMENT, ETC.  Each Guarantor agrees that this Guaranty
shall continue to be effective or be reinstated, as the case may be, if at any
time any payment (in

                                     5
<PAGE>

whole or in part) of any of the Obligations is rescinded or must otherwise be
restored by any Lender Party or any holder of any Note, upon the insolvency,
bankruptcy or reorganization of either Borrower, any other Obligor or
otherwise, all as though such payment had not been made.

     SECTION 2.5.  WAIVER, ETC.  Each Guarantor hereby waives presentment,
promptness, diligence, notice of acceptance and any other notice with respect to
any of the Obligations of either Borrower or any other Obligor and this Guaranty
and any requirement that either Co-Agent, any other Lender Party or any holder
of any Note protect, secure, perfect or insure any security interest or Lien, or
any property subject thereto, or exhaust any right or take any action against
either Borrower, any other Obligor or any other Person (including any other
guarantor) or entity or any collateral securing the Obligations of either
Borrower or any other Obligor, as the case may be.

     SECTION 2.6.  SUBROGATION, ETC.  At any time that a payment is made by any
Guarantor with respect to the Obligations, such Guarantor shall have a right of
contribution against each other Obligor and each other Obligor shall have an
obligation to indemnify such Guarantor in the maximum amount permitted by
Applicable Law, which right of contribution and indemnity shall be subject to
adjustment at the time of any subsequent payment with respect to the
Obligations; PROVIDED, HOWEVER, that the maximum aggregate liability of any
Guarantor shall not exceed the maximum amount of liability that such Guarantor
can incur without rendering such contribution and indemnity rights void or
voidable under Applicable Law relating to fraudulent conveyance or fraudulent
transfers, and not for any greater amount; PROVIDED, FURTHER, HOWEVER, that no
Guarantor will exercise any rights which it may acquire by reason of any payment
made hereunder, whether by way of rights of subrogation, reimbursement or
otherwise, until the prior payment, in full and in cash, of all Obligations of
the Borrowers and each other Obligor.  Any amount paid to any Guarantor on
account of any payment made hereunder prior to the payment in full of all
Obligations of the Borrowers and each other Obligor shall be held in trust for
the benefit of the Lender Parties and each holder of a Note and shall
immediately be paid to the Administrative Agent and credited and applied against
the Obligations of the Borrowers and each other Obligor, whether matured or
unmatured, in accordance with the terms of the Credit Agreement; PROVIDED,
HOWEVER, that if

          (a)    any Guarantor has made payment to the Lender Parties and each
     holder of a Note of all or any part of the Obligations of the Borrowers or
     any other Obligor, and

          (b)    all Obligations of the Borrowers and each other Obligor have
     been paid in full and all Commitments and

                                     6
<PAGE>

     Letters of Credit have expired or been permanently terminated,

at such Guarantor's request, the Administrative Agent, on behalf of the Lender
Parties and the holders of the Notes, will execute and deliver to such Guarantor
appropriate documents (without recourse and without representation or warranty)
necessary to evidence the transfer by subrogation to such Guarantor of an
interest in the Obligations of the Borrowers and each other Obligor resulting
from such payment by such Guarantor.  In furtherance of the foregoing, for so
long as any Obligations, Letters of Credit or Commitments remain outstanding,
each Guarantor shall refrain from taking any action or commencing any proceeding
against either Borrower or any other Obligor (or its successors or assigns,
whether in connection with a bankruptcy proceeding or otherwise) to recover any
amounts in respect of payments made under this Guaranty to any Lender Party or
any holder of a Note.  Each Guarantor hereby waives any benefit of, and any
right to participate in, any collateral now or hereafter held by any Lender
Party.

     SECTION 2.7.   SUCCESSORS, TRANSFEREES AND ASSIGNS; TRANSFERS OF NOTES,
ETC.  This Guaranty shall:

          (a)    be binding upon each Guarantor, and its respective successors,
     transferees and assigns; and

          (b)    inure to the benefit of and be enforceable by each Co-Agent and
     each other Lender Party.

Without limiting the generality of the foregoing CLAUSE (b), any Lender may
assign or otherwise transfer (in whole or in part) any Note or Revolving Loan
held by it to any other Person or entity, and such other Person or entity shall
thereupon become vested with all rights and benefits in respect thereof granted
to such Lender under any Loan Document (including this Guaranty) or otherwise,
subject, however, to any contrary provisions in such assignment or transfer, and
to the provisions of Section 11.11 of the Credit Agreement.

                     REPRESENTATIONS AND WARRANTIES

     SECTION 3.1.   REPRESENTATIONS AND WARRANTIES.  Each Guarantor hereby
represents and warrants unto each Lender Party as set forth in this Article.

     SECTION 3.1.1. RELATIONSHIP OF PARTIES.  (a) Such Guarantor and each
Borrower are distinct and separate entities operating as


                                     7

<PAGE>

independent corporations; (b) such Guarantor has received copies of the 
Credit Agreement and is familiar with and fully understands all of its terms 
and conditions; (c) neither Co-Agent has made any representations or 
warranties to such Guarantor regarding the creditworthiness of the Borrowers 
or the prospects of repayment from sources other than the Borrowers; (d) this 
Guaranty is executed at the request of the Borrowers; (e) such Guarantor has 
established adequate means of obtaining from the Borrowers on a continuing 
basis financial and other information pertaining to the business of the 
Borrowers; (f) each of the Borrowers and such Guarantor is solvent, and (g) 
such Guarantor assumes full responsibility for keeping fully informed with 
respect to the business, operation, condition and assets of the Borrowers.  
Such Guarantor hereby agrees that neither Co-Agent shall have any duty to 
disclose or report to such Guarantor any information now or hereafter known 
to such Co-Agent relating to the business, operation, condition and assets of 
the Borrowers. Neither Co-Agent shall have any duty to inquire into the 
authority or powers of either Borrower or any officer, employee or agent of 
either Borrower with regard to any Obligations, and all Obligations made or 
created in good faith in reliance upon the professed exercise of any such 
authority or powers shall be guaranteed hereunder.

                                  ARTICLE IV

                                COVENANTS, ETC.

     SECTION 4.1.  OBLIGATIONS UNDER CREDIT AGREEMENT.  Each Guarantor jointly
and severally covenants and agrees that, so long as any portion of the
Obligations shall remain unpaid, all Letters of Credit have not expired or been
terminated or any Lender shall have any outstanding Commitment, such Guarantor
will comply with and perform its obligations under the Credit Agreement to the
extent applicable to such Guarantor.


                                   ARTICLE V

                           MISCELLANEOUS PROVISIONS

     SECTION 5.1.  LOAN DOCUMENT.  This Guaranty is a Loan Document executed
pursuant to the Credit Agreement and shall (unless otherwise expressly indicated
herein) be construed, administered and applied in accordance with the terms and
provisions thereof.

     SECTION 5.2.  DEED OF TRUST ON REAL PROPERTY; ADDITIONAL WAIVERS.  (a) Each
Guarantor authorizes the Administrative Agent, with the consent of the Required
Lenders, without notice 


                                       8

<PAGE>

or demand and without affecting the liability of such Guarantor hereunder, to 
release and reconvey (with or without the receipt of any consideration) any 
lien against any or all real or personal property security for the 
Obligations, to foreclose any or all deeds of trust, mortgages, security 
agreements or other instruments or agreements by judicial or nonjudicial 
sale, and to exercise any other remedy against the Borrowers or any other 
Obligor, any security or any other guarantor, all without affecting the 
liability of such Guarantor hereunder.  Each Guarantor acknowledges that, 
pursuant to Section 580d of the California Code of Civil Procedure, the 
exercise by the Administrative Agent or any other Lender Party of certain 
remedies, including the remedy of non-judicial foreclosure, against any 
collateral security for the Obligations would make the Borrowers immune from 
a deficiency judgment, thereby preventing any recovery that such Guarantor 
might have obtained from the Borrowers pursuant to its rights of subrogation 
and acknowledges further that, in the absence of this SECTION 5.2, such a 
loss of such Guarantor's rights may entitle such Guarantor to assert a 
defense to this Guaranty based on Section 580d of the California Code of 
Civil Procedure as interpreted in UNION BANK v. GRADSKY, 265 Cal. App. 2d 40 
(1968) against a claim by the Administrative Agent or any other Lender Party 
against such Guarantor in respect of such deficiency.  Each Guarantor 
expressly waives any defense to the recovery by the Administrative Agent or 
any other Lender Party from such Guarantor of any deficiency after a 
nonjudicial sale, including without limitation any defense arising as a 
result of any election of remedies by the Administrative Agent or any other 
Lender Party which limits or destroys such Guarantor's subrogation rights or 
such Guarantor's right to proceed against the Borrowers for reimbursement 
(including without limitation any election by the Administrative Agent or any 
other Lender Party to exercise its rights under the power of sale in any 
mortgage or deed of trust and any consequential loss by such Guarantor of the 
right to recover any deficiency from the Borrowers as described above).  
Each Guarantor waives any defenses or benefits that may be derived from 
California Code of Civil Procedure Sections 580a, 580b, 580d or 726, or 
Section 2848 of the California Civil Code or comparable provisions of the 
laws of the State of California or any other jurisdiction, and all other 
suretyship defenses it would otherwise have under California law or the laws 
of any other jurisdiction and acknowledges and agrees that the Administrative 
Agent and each other Lender Party are relying on this waiver in creating the 
Obligations, and that this waiver is a material part of the consideration 
which the Administrative Agent and each other Lender Party are receiving for 
creating the Obligations.  Each Guarantor waives any right to receive notice 
of any judicial or nonjudicial sale or foreclosure of any real property, and 
the failure of such Guarantor to receive such 


                                       9

<PAGE>

notice shall not impair or affect such Guarantor's liability hereunder.

          (b) Each Guarantor waives any rights and defenses available to such
Guarantor by reason of Sections 2787 to 2855, inclusive, of the California Civil
Code including, without limitation, (1) any defenses such Guarantor may have to
its obligations under this Guaranty by reason of an election of remedies by any
Lender Party and (2) any rights or defenses such Guarantor may have by reason of
protection afforded to the Borrowers with respect to any of the Obligations of
the Borrowers pursuant to the antideficiency or other laws of California
limiting or discharging any of the Obligations of the Borrowers, including,
without limitation, Sections 580a, 580d, or 726 of the California Code of Civil
Procedure.

          (c) Each Guarantor waives all rights and defenses arising out of an
election of remedies by any Lender Party, even though that election of remedies,
such as a nonjudicial foreclosure with respect to security for a guaranteed
obligation, has destroyed such Guarantor's rights of subrogation and
reimbursement against the Borrowers by the operation of Section 580d of the
California Code of Civil Procedure or otherwise.

          (d) No provision or waiver of this Guaranty shall be construed as
limiting the generality of any other waiver contained in this Guaranty.

     SECTION 5.3.  BINDING ON SUCCESSORS, TRANSFEREES AND ASSIGNS; ASSIGNMENT. 
In addition to, and not in limitation of, SECTION 2.7, this Guaranty shall be
binding upon each Guarantor and its successors, transferees and assigns and
shall inure to the benefit of and be enforceable by each Lender Party and each
holder of a Note and their respective successors, transferees and assigns (to
the full extent provided pursuant to SECTION 2.7); PROVIDED, HOWEVER, that no
Guarantor may assign any of its obligations hereunder without the prior written
consent of the Co-Agents and each other Lender Party.

     SECTION 5.4.  AMENDMENTS. ETC.  No amendment to or waiver of any provision
of this Guaranty, nor consent to any departure by any Guarantor herefrom, shall
in any event be effective unless the same shall be in writing and signed by each
Co-Agent and the Required Lenders, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given.

     SECTION 5.5.  ADDRESSES FOR NOTICES TO EACH GUARANTOR. All notices and
other communications hereunder to each Guarantor shall be in writing (including
by Telex or facsimile) and mailed or telegraphed or delivered to it, addressed
to it at the address 


                                      10

<PAGE>

set forth below its signature hereto or at such other address as shall be 
designated by such Guarantor in a written notice to the Administrative Agent 
at the address specified in the Credit Agreement complying as to delivery 
with the terms of this Section.  Any notice, if mailed and properly addressed 
with postage prepaid or if properly addressed and sent by pre-paid courier 
service, shall be deemed given when received; any notice, if transmitted by 
Telex or facsimile, shall be deemed given when transmitted (answerback 
confirmed in the case of Telexes).

     SECTION 5.6.  NO WAIVER; REMEDIES.  In addition to, and not in limitation
of, SECTION 2.3 and SECTION 2.5, no failure on the part of any Lender Party or
any holder of a Note to exercise, and no delay in exercising, any right
hereunder shall operate as a waiver thereof; nor shall any single or partial
exercise of any right hereunder 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.

          SECTION 5.7.   SECTION CAPTIONS.  Section captions used in this
Guaranty are for convenience of reference only, and shall not affect the
construction of this Guaranty.

          SECTION 5.8.  SETOFF.  In addition to, and not in limitation of, any
rights of any Lender Party or any holder of a Note under applicable law, each
Lender Party and each such holder shall, with the consent of the Required
Lenders, upon the occurrence of any Default described in any of CLAUSES (a)
through (d) of Section 9.1.9 of the Credit Agreement or, with the consent of the
Required Lenders, upon the occurrence of any Event of Default, have the right to
appropriate and apply to the payment of the obligations of each Guarantor owing
to it hereunder, whether or not then due, and each Guarantor hereby grants to
each Lender Party and each such holder a continuing security interest in, any
and all balances, credits, deposits, accounts or moneys of such Guarantor then
or thereafter maintained with such Lender Party or such holder and any and all
property of every kind or description of or in the name of such Guarantor now or
hereafter, for any reason or purpose whatsoever, in the possession or control
of, or in transit to, such Lender Party, such holder or any agent or bailee for
such Lender Party or such holder; PROVIDED, HOWEVER, that any such appropriation
and application shall be subject to the provisions of Section 5.8 of the Credit
Agreement.

     SECTION 5.9.  SEVERABILITY.  Wherever possible each provision of this
Guaranty shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Guaranty shall be prohibited by or
invalid under such law, such provision shall be ineffective to the extent of
such prohibition or invalidity, without invalidating the 


                                      11

<PAGE>

remainder of such provision or the remaining provisions of this Guaranty.

     SECTION 5.10.  GOVERNING LAW, ENTIRE AGREEMENT. ETC.  THIS GUARANTY SHALL
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE
OF CALIFORNIA.  THIS GUARANTY AND THE OTHER LOAN DOCUMENTS CONSTITUTE THE ENTIRE
UNDERSTANDING AMONG THE PARTIES HERETO WITH RESPECT TO THE SUBJECT MATTER HEREOF
AND SUPERSEDE ANY PRIOR AGREEMENTS, WRITTEN OR ORAL, WITH RESPECT THERETO.

     SECTION 5.11.  FORUM SELECTION AND CONSENT TO JURISDICTION. ANY LITIGATION

STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF CALIFORNIA; PROVIDED,
HOWEVER, THAT ANY SUIT SEEKING ENFORCEMENT AGAINST ANY PROPERTY MAY BE BROUGHT,

UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF CALIFORNIA FOR THE
PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE AND IRREVOCABLY AGREES TO BE

GUARANTOR FURThER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED
MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF
CALIFORNIA.  EACH GUARANTOR HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY HAVE OR HEREAFTER
MAY HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT
REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN
