   1. BASIS OF PRESENTATION

   The accompanying unaudited condensed consolidated financial
   statements of Bio-Rad Laboratories, Inc. ("Bio-Rad" or the
   "Company"), reflect all adjustments which are, in the opinion of
   management, necessary to a fair statement of the results of the
   interim periods presented.  All such adjustments are of a normal
   recurring nature.  The condensed consolidated financial
   statements should be read in conjunction with the notes to
   consolidated financial statements contained in the Company's
   Annual Report for the year ended December 31, 1997 (the Company's
   1997 Annual Report).  Certain amounts in the financial statements
   of the prior year have been reclassified to be consistent with
   the 1998 presentation.

   4.   LONG-TERM DEBT

   The Company entered into a $100 million revolving credit
   agreement on May 15, 1998, replacing the $60 million credit
   agreement previously in place.  The new agreement provides for
   borrowings on an unsecured basis through May 15, 2003.  Interest
   is based upon Eurodollar or prime rates.

   5.   EARNINGS PER SHARE

   Weighted average shares used for diluted earnings per share
   include the dilutive effect of outstanding stock options of
   151,000 and 120,000 shares for the quarters ended June 30, 1998
   and 1997, respectively.

   Weighted average shares used for diluted earnings per share
   include the dilutive effect of outstanding stock options of
   139,000 and 144,000 shares for the year-to-date periods ended
   June 30, 1998 and 1997, respectively.

   Options to purchase 140,000 and 122,000 shares of common stock
   were outstanding during 1998 and 1997, respectively, but were
   excluded from the computation of diluted earnings per share
   because the exercise price of the options was greater than the
   average market price of the common shares.  The options were
   still outstanding at June 30, 1998.

   6.   COMPREHENSIVE INCOME

   In the first quarter of 1998, the Company adopted Statement of
   Financial Accounting Standards (SFAS) No. 130, "Reporting
   Comprehensive Income."  Comprehensive income is defined as the
   change in equity of a business during a period from transactions
   and other events and circumstances from non-owner sources.  Under
   SFAS No. 130, the term "comprehensive income" is used to describe
   the total of net earnings plus other comprehensive income which,
   for the Company, includes foreign currency translation
   adjustments and unrealized gains and losses on marketable
   securities classified as available-for-sale.

   The adoption of SFAS No. 130 did not impact the calculation of
   net income or earnings per share nor did it impact reported
   assets, liabilities or total stockholders' equity.  It did impact
   the presentation of the components of stockholders' equity within
   the balance sheet and will result in the presentation of the
   components of comprehensive income within an annual financial
   statement, which must be displayed with the same prominence as
   other financial statements.

   7.   NEW FINANCIAL ACCOUNTING STANDARD

   In June 1998, the Financial Accounting Standards Board issued
   SFAS No. 133, "Accounting for Derivative Instruments and Hedging
   Activities," effective for fiscal years beginning after June 15,
   1999, with early adoption permitted.  This statement establishes
   accounting and reporting standards requiring companies to record
   all derivatives on the balance sheet as either assets or
   liabilities and measure those instruments at fair value.  The
   manner in which companies are to record gains or losses resulting
   from changes in the values of those derivatives depends on the
   use of the derivative and whether it qualifies for hedge
   accounting.  The Company has not yet quantified the impacts of
   adopting SFAS No. 133 on its financial statements and has not
   determined the timing of adoption of SFAS No. 133.

              Three Months Ended June 30, 1998 Compared to
                    Three Months Ended June 30, 1997

   Corporate Results - Sales, Margins and Expenses

   Net sales (sales) in the second quarter of 1998 were $107.9
   million compared to $105.8 million in the second quarter of 1997.
   For the second quarter of 1998, the effect of a strengthened U.S.
   dollar reduced international sales by approximately $2.9 million
   when compared to sales based upon 1997 exchange rates.  Sales
   increased in Clinical Diagnostics, were flat in Life Science and
   decreased in Analytical Instruments.  Eliminating the effects of
   a strengthened U.S. dollar, sales increased 16% in Clinical
   Diagnostics, 2% in Life Science and were down 10% in Analytical
   Instruments.  Both the Analytical Instruments and Life Science
   segments have been negatively impacted by the economic conditions
   in Asia.  In addition to Asia, the Analytical Instruments segment
   has been impacted by a general slow down in the markets it
   serves.  Approximately half of the increase in Clinical
   Diagnostics sale growth can be directly attributed to the
   acquisition of the Chiron Diagnostics controls business in the
   fourth quarter of 1997.

                                   7

   Consolidated gross margins were 54.5% for the second quarter of
   1998 compared to 55.5% for the second quarter of 1997 and 55.7%
   for all of 1997.  Gross margins were impacted by the
   strengthening U.S. dollar and declined in all three of the
   Company's segments.  Diagnostic margins declined, in part, from
   the Chiron acquisition, where several supply agreements existed
   to wholesale diagnostic controls.  Analytical Instruments margins
   are negatively impacted by the absorption of period costs over a
   smaller sales amount.

   Selling, general and administrative expense (SG&A) at 38.4% of
   sales in the second quarter of 1998 is virtually unchanged from
   38.3% of sales in the comparable period of 1997.  To improve
   overall profitability, one of the long-term objectives of
   management is to control SG&A growth as a fraction of sales
   growth.

   Product research and development expense (R&D) decreased from the
   second quarter of 1997, both in absolute dollars and as a percent
   of sales.  Compared to the second quarter of 1997, both Clinical
   Diagnostics and Analytical Instruments increased R&D spending
   although Clinical Diagnostics increased spending at a rate less
   than sales growth.  As part of the Company's continuing
   commitment to long-term growth, 1997 was a year of expanding R&D.
   In 1998, management plans to continue R&D spending, but monitor
   it to maintain an appropriate growth rate.

   Corporate Results - Non-Operating Items

   Interest expense was $816,000 more in the second quarter of 1998
   than the comparable period of 1997 principally as a result of
   higher average borrowings.  Borrowings increased in connection
   with acquisitions in the fourth quarter of 1997 and investments
   in the second quarter of 1998.

   Investment income in both years includes gains on sales of
   marketable securities and interest income from short-term
   investments.  During the second quarter of 1998, Bio-Rad realized
   significant investment income, $4.9 million, as it realigned its
   investment in marketable securities in order to increase its
   position in Instrumentation Laboratory.

   Net other income and expense in the second quarter of 1998 is
   primarily goodwill amortization. Net other income and expense in
   the second quarter of 1997 was primarily net exchange losses and
   goodwill amortization.

   The Company's effective tax rate for the second quarter of 1998
   was 29% compared to 28% for all of 1997.  The tax rate for both
   years reflects the utilization of loss carryforwards, foreign
   sales corporation benefits and foreign tax credits.  However, as

                                   8


   <PAGE>


   loss carryforwards are exhausted the benefits realized will
   decline in comparison to prior periods and the effective tax rate
   will rise.

               Six Months Ended June 30, 1998 Compared to
                     Six Months Ended June 30, 1997

   Corporate Results - Sales, Margins and Expenses

   Sales in the first half of 1998 were $224.1 million compared to
   $211.6 million in the first half of 1997, an increase of 6%.  For
   the first half of 1998, the effect of a strengthened U.S. dollar
   reduced international sales by approximately $7.5 million
   compared to sales based upon 1997 exchange rates.  Sales
   increased 14% in Clinical Diagnostics, 4% in Analytical
   Instruments and were flat in Life Science.  Approximately half of
   the increase in Clinical Diagnostics sale growth can be directly
   attributed to the acquisition of the Chiron Diagnostics controls
   business in the fourth quarter of 1997.  Sales increases in
   Analytical Instruments are attributed to limited growth in the
   products sold into the semiconductor test and manufacturing
   equipment market.

   Consolidated gross margins were 54.9% for the first six months of
   1998 compared to 57.1% for the first six months of 1997 and 55.7%
   for all of 1997.  Gross margins declined in all three of the
   Company's segments.  Life Science margins declined as a result of
   the strengthening dollar in Asia and Europe and price discounting
   in Europe.  Diagnostic margins declined, in part, from the Chiron
   acquisition, where several supply agreements existed to wholesale
   diagnostic controls.  Also, higher service costs and some price
   erosion lowered diagnostic margins in the diabetes product line.
   Analytical Instruments margins were negatively impacted by an
   increasingly weak semiconductor market and the strengthening
   dollar.

   SG&A decreased to 36.9% of sales in the first half of 1998 from
   38.4% of sales in the comparable period of 1997.  The
   strengthened U.S. dollar reduced international SG&A by
   approximately $2.3 million or 1.0% of sales.  To improve overall
   profitability, one of the long-term objectives of management is
   to control SG&A growth as a fraction of sales growth.  On a
   currency neutral basis, SG&A for Life Science increased by 1%,
   and SG&A for Analytical Instruments decreased by 2% when compared
   to 1997.  Clinical Diagnostics increased SG&A spending but at a
   rate far less than sales growth.  The 1997 fourth quarter
   acquisition did not add significantly to the fixed SG&A burden of
   Clinical Diagnostics.

   Consolidated R&D decreased from the first half of 1997, both in
   absolute dollars and as a percent of sales.  Compared to the
   first half of 1997, Clinical Diagnostics and Analytical

                                   9


   <PAGE>


   Instruments increased R&D spending by approximately $200,000
   each.  As part of the Company's continuing commitment to long-
   term growth, 1997 was a year of expanding R&D.  In 1998,
   management plans to continue R&D spending, but monitor it to
   maintain an appropriate growth rate.

   Corporate Results - Non-operating Items

   Interest expense was $1.3 million more in the first half of 1998
   than the comparable period of 1997 principally as a result of
   higher average borrowings.  Borrowings increased in connection
   with acquisitions in the fourth quarter of 1997 and investments
   in the second quarter of 1998.

   Investment income in both years includes gains on sales of
   marketable securities and interest income from short-term
   investments.  During the second quarter of 1998, Bio-Rad realized
   significant investment income, $4.9 million, as it realigned its
   investment in marketable securities in order to increase its
   position in Instrumentation Laboratory.

   Net other income and expense in the first half of 1998 includes
   goodwill amortization and non-operating legal costs.  Net other
   income and expense in the first half of 1997 was primarily net
   exchange losses and goodwill amortization.

   As expected, the Company's effective tax rate increased from 28%
   to 29% for the first half of 1998.  The tax rate for both years
   reflects the utilization of loss carryforwards, foreign sales
   corporation benefits and foreign tax credits.  However, as loss
   carryforwards are exhausted the benefits realized will decline in
   comparison to prior periods and the effective tax rate will rise.

   Financial Condition

   At June 30, 1998, the Company had available $13.5 million in cash
   and cash equivalents, $53.0 million under its principal revolving
   credit agreement and marketable securities with a market value of
   $27.7 million, a majority of which could be readily converted to
   cash.  On May 15, 1998, the Company entered into a new $100
   million revolving credit agreement replacing the $60 million
   revolving credit agreement (see Note 4).

   Financing activities, principally borrowings under the Company's
   principal revolving credit agreement, and cash provided by
   operating activities provided the Company with the cash flow
   necessary to support investing activities.  During the second
   quarter the Company realized investment income by selling a
   portion of its investment portfolio.  Sales are expected to
   continue throughout the remainder of the year, however, the
   magnitude of any gains are not expected to match the second
   quarter.  The cash generated by these sales was used to increase

                                   10


   <PAGE>


   Bio-Rad's holdings in Instrumentation Laboratory, S.p.A., an
   Italian based clinical diagnostics company with annual revenues
   of over $200 million.  Bio-Rad currently holds as an investment
   approximately 23% of Instrumentation Laboratory.

   At June 30, 1998, consolidated accounts receivable increased by
   $3.1 million from December 31, 1997.  Excluding the effects of
   the strengthened U.S. dollar, accounts receivable increased by
   $4.8 million.  The increase is a result of larger sales late in
   the quarter when compared to the prior period, the Company
   deciding to factor less in Southern Europe and a slow down in
   payments in Asia.

   At June 30, 1998, consolidated net inventories were $1.9 million
   higher than at December 31, 1997.  The increase in inventory
   occurred in the Life Science segment and was designed to meet
   short term requirements as manufacturing process changes are
   implemented which, by year-end, should result in overall lower
   inventories.   Management continues to monitor inventory levels
   and regularly reviews the impact of obsolescence in current
   inventory caused by the introduction of new products.

   In February 1998, the Board of Directors authorized the Company
   to repurchase up to an additional $10 million of common stock
   over an indefinite period of time.  This is the third such
   authorization since July 1996 bringing the total authorized to
   $18 million.  Through July 1998, the Company has repurchased
   244,700 shares of Class A common stock and 30,000 shares of Class B
   common stock for a total of $7.4 million.  The repurchase is
   designed to improve shareholder value and to satisfy the
   Company's obligations under the employee stock purchase and stock
   option plans.

   The Company continues to regularly review acquisition
   opportunities; currently no material acquisitions have reached a
   stage beyond exploratory discussions.

   Other than statements of historical fact, statements made in this
   report include forward looking statements, such as statements
   with respect to the Company's future financial performance,
   operating results, plans and objectives.  Actual results may
   differ materially from those currently anticipated depending on a
   variety of risk factors.

   shown in the consolidated financial statements of the
   Borrower and its Subsidiaries as at the beginning of the
   twelve-month period ending with the month in which such
   determination is made.

        "Total Indebtedness" means, as of any date of
   determination, the amount (determined in conformity with
   GAAP) of all Indebtedness of the Borrower and all its
   Subsidiaries, determined on a consolidated basis, created or
   assumed by any of such Persons.

        "Total Indebtedness / Adjusted EBITDA Ratio" means, as
   of any date of determination, the quotient of the Total
   Indebtedness of the Borrower and its Subsidiaries
   (determined on a consolidated basis) as of such date divided
   by the Adjusted EBITDA of the Borrower and its Subsidiaries
   (determined on a consolidated basis) as of such date.

   as a Floating Rate Advance or Eurodollar Advance.

        "Unfunded Liabilities" means the amount (if any) by
   which the present value of all vested nonforfeitable
   benefits under all Single Employer Plans exceeds the fair
   market value of all such Plan assets allocable to such
   benefits, all determined as of the then most recent
   valuation date for such Plans.

        "Unmatured Default" means an event which but for the
   lapse of time or the giving of notice, or both, would
   constitute a Default.

        The foregoing definitions shall be equally applicable
   to both the singular and plural forms of the defined terms.


                              ARTICLE II

                              THE CREDITS

        2.1. Commitment.  From and including the date of this
   Agreement and prior to the Facility Termination Date, each
   Lender severally agrees, on the terms and conditions set
   forth in this Agreement, to make Loans to the Borrower from
   time to time in amounts not to exceed in the aggregate at
   any one time outstanding the amount of its Commitment;
   provided, however, that the aggregate amount of Loans made
   by all Lenders at any one time outstanding shall not exceed
   the Aggregate Commitment.  Subject to the terms of this
   Agreement, the Borrower may borrow, repay and reborrow at
   any time prior to the Facility Termination Date.  The
   Commitments to lend hereunder shall expire on the Facility
   Termination Date.

        2.2. Required Payments; Termination.  Any outstanding
   Advances and all other unpaid Obligations shall be paid in
   full by the Borrower on the Facility Termination Date.

        2.3. Ratable Loans.  Each Advance hereunder shall
   consist of Loans made from the several Lenders ratably in
   proportion to the ratio that their respective Commitments
   bear to the Aggregate Commitment.

        2.4. Types of Advances.  The Advances may be Floating
   Rate Advances or Eurodollar Advances, or a combination
   thereof, selected by the Borrower in accordance with
   Sections 2.8 and 2.9.

        2.5. Commitment Fee; Reductions in Aggregate
   Commitment.  The Borrower agrees to pay to the Agent for the
   account of each Lender a commitment fee equal to the
   Applicable Fee Rate multiplied by the amount, calculated
   daily, equal to such Lender's Commitment minus such Lender's
   pro rata share of all outstanding Loans, from the date
   hereof to and including the Facility Termination Date,
   payable quarterly, in arrears, on the last day of each
   calendar quarter and on the Facility Termination Date.  The
   Borrower may permanently reduce the Aggregate Commitment in

                                      10

   <PAGE>

   whole, or in part ratably among the Lenders in the minimum
   amount of $5,000,000 and integral multiples of
   $1,000,000 in excess thereof, upon at least ten Business
   Days' written notice to the Agent, which notice shall
   specify the amount of any such reduction, provided, however,
   that the amount of the Aggregate Commitment may not be
   reduced below the aggregate principal amount of the
   outstanding Advances.  All accrued commitment fees shall be
   payable on the effective date of any termination of the
   obligations of the Lenders to make Loans hereunder.

        2.6. Minimum Amount of Each Advance.  Each Fixed Rate
   Advance shall be in the minimum amount of $4,000,000 (and
   in multiples of $500,000 if in excess thereof), and each
   Floating Rate Advance shall be in the minimum amount of
   $200,000 (and in multiples of $100,000 if in excess
   thereof), provided, however, that any Floating Rate Advance
   may be in the amount of the unused Aggregate Commitment.

        2.7. Optional Principal Payments.  The Borrower may
   from time to time pay, without penalty or premium, all
   outstanding Floating Rate Advances, or, in a minimum
   aggregate amount of $100,000 or any integral multiple of
   $100,000 in excess thereof, any portion of the
   outstanding Floating Rate Advances upon notice not later
   than noon (Chicago time) on the date of prepayment to the
   Agent.  Any Fixed Rate Advance may be paid prior to the last
   day of the applicable Interest Period upon payment of all
   amounts due under Section 3.4.  The Borrower shall give the
   Agent notice not later than noon (Chicago time) on the date
   of any prepayment of a Floating Rate Advance, and not later
   than noon (Chicago time) two Business Days prior to any
   prepayment of any Fixed Rate Advance.  The Agent will
   promptly notify each Lender of its receipt of any such
   notice.

        2.8. Method of Selecting Types and Interest Periods for
   New Advances.  The Borrower shall select the Type of Advance
   and, in the case of each Fixed Rate Advance, the Interest
   Period applicable to each Advance from time to time.  The
   Borrower shall give the Agent irrevocable notice (a
   "Borrowing Notice") not later than noon (Chicago time) on
   the proposed Borrowing Date of each Floating Rate Advance
   and not later than noon (Chicago time) at least three
   Business Days before the Borrowing Date for each Eurodollar
   Advance, specifying:

             (i)   the Borrowing Date, which shall be a Business
                   Day, of such Advance,

             (ii)  the aggregate amount of such Advance,

             (iii) the Type of Advance selected, and

             (iv)  in the case of each Fixed Rate Advance, the
                   Interest Period applicable thereto.

   Not later than 2:00 p.m. (Chicago time) on each Borrowing
   Date, each Lender shall make available its Loan or Loans, in
   funds immediately available in Chicago to the Agent at its
   address specified pursuant to Article XIII.  The Agent will
   make the funds so received from the Lenders available to the
   Borrower at the Agent's aforesaid address.

                                      11

   <PAGE>

        2.9. Conversion and Continuation of Outstanding
   Advances.  Floating Rate Advances shall continue as Floating
   Rate Advances unless and until such Floating Rate Advances
   are converted into Fixed Rate Advances.  Each Fixed Rate
   Advance shall continue as a Fixed Rate Advance until the end
   of the then applicable Interest Period therefor, at which
   time such Fixed Rate Advance shall be automatically
   converted into a Floating Rate Advance unless the Borrower
   shall have given the Agent a Conversion/Continuation Notice
   requesting that, at the end of such Interest Period, such
   Fixed Rate Advance either continue as a Fixed Rate Advance
   for the same or another Interest Period or be converted into
   an Advance of another Type.  Subject to the terms of Section
   2.6, the Borrower may elect from time to time to convert all
   or any part of an Advance of any Type into any other Type or
   Types of Advances; provided that any conversion of any Fixed
   Rate Advance shall be made on, and only on, the last day of
   the Interest Period applicable thereto.  The Borrower shall
   give the Agent irrevocable notice (a
   "Conversion/Continuation Notice") of each conversion of an
   Advance or continuation of a Fixed Rate Advance not later
   than 10:00 a.m. (Chicago time) on the day of a conversion
   into a Floating Rate Advance, or three Business Days, in the
   case of a conversion into or continuation of a Eurodollar
   Advance, prior to the date of the requested conversion or
   continuation, specifying:

             (i)   the requested date, which shall be a Business
                   Day, of such conversion or continuation;

             (ii)  the aggregate amount and Type of the Advance
                   which is to be converted or continued; and

             (iii) the amount and Type(s) of Advance(s) into
                   which such Advance is to be converted or
                   continued and, in the case of a conversion
                   into or continuation of a Fixed Rate Advance,
                   the duration of the Interest Period
                   applicable thereto.

        2.10.  Interest Rates.  Each Floating Rate Advance
   shall bear interest on the outstanding principal amount
   thereof, for each day from and including the date such
   Advance is made or is converted from a Fixed Rate Advance
   into a Floating Rate Advance pursuant to Section 2.9 to but
   excluding the date it becomes due or is converted into a
   Fixed Rate Advance pursuant to Section 2.9 hereof, at a rate
   per annum equal to the Floating Rate for such day.  Changes
   in the rate of interest on that portion of any Advance
   maintained as a Floating Rate Advance will take effect
   simultaneously with each change in the Alternate Base Rate.
   Each Fixed Rate Advance shall bear interest on the
   outstanding principal amount thereof from and including the
   first day of the Interest Period applicable thereto to (but
   not including) the last day of such Interest Period at the
   interest rate determined as applicable to such Fixed Rate
   Advance.  No Interest Period may end after the Facility
   Termination Date.

        2.11.  Rates Applicable After Default.
   Notwithstanding anything to the contrary contained in
   Section 2.8 or 2.9, during the continuance of a Default or
   Unmatured Default no Advance may be made as, converted into
   or rolled over as a Fixed Rate Advance without the prior
   written consent of the Required Lenders.  During the
   continuance of a Default the Required Lenders may, at their
   option, by written notice to the Borrower (which notice may
   be revoked at the option of the Required Lenders
   notwithstanding any provision of Section 8.2 requiring

                                      12

   <PAGE>

   unanimous consent of the Lenders to changes in interest
   rates), declare that all outstanding Loans shall bear
   interest at a rate per annum equal to the Floating Rate plus
   2 1/2% per annum.

        2.12.  Method of Payment.  All payments of the
   Obligations hereunder shall be made, without setoff,
   deduction, or counterclaim, in immediately available funds
   to the Agent at the Agent's address specified pursuant to
   Article XIII, or at any other Lending Installation of the
   Agent specified in writing by the Agent to the Borrower, by
   noon (local time) on the date when due and shall be applied
   ratably by the Agent among the Lenders.  Each payment
   delivered to the Agent for the account of any Lender shall
   be delivered promptly by the Agent to such Lender in the
   same type of funds that the Agent received at its address
   specified pursuant to Article XIII or at any Lending
   Installation specified in a notice received by the Agent
   from such Lender.  The Agent is hereby authorized to charge
   the account of the Borrower maintained with First Chicago
   for each payment of principal, interest and fees as it
   becomes due hereunder.

        2.13.  Notes; Telephonic Notices.  Each Lender is
   hereby authorized to record the principal amount of each of
   its Loans and each repayment on the schedule attached to its
   Note, provided, however, that the failure to so record shall
   not affect the Borrower's obligations under such Note.  The
   Borrower hereby authorizes the Lenders and the Agent to
   extend, convert or continue Advances, effect selections of
   Types of Advances and to transfer funds based on telephonic
   notices made by any person or persons the Agent or any
   Lender in good faith believes to be acting on behalf of the
   Borrower.  The Borrower agrees to deliver promptly to the
   Agent a written confirmation, if such confirmation is
   requested by the Agent or any Lender, of each telephonic
   notice signed by an Authorized Officer.  If the written
   confirmation differs in any material respect from the action
   taken by the Agent and the Lenders, the records of the Agent
   and the Lenders shall govern absent manifest error.

        2.14.  Interest Payment Dates; Interest and Fee Basis.
   Interest accrued on each Floating Rate Advance shall be
   payable on the last day of each month, commencing with the
   first such date to occur after the date hereof, on any date
   on which the Floating Rate Advance is prepaid, whether due
   to acceleration or otherwise, and at maturity.  Interest
   accrued on that portion of the outstanding principal amount
   of any Floating Rate Advance converted into a Fixed Rate
   Advance on a day other than a Payment Date shall be payable
   on the date of conversion.  Interest accrued on each Fixed
   Rate Advance shall be payable on the last day of its
   applicable Interest Period, on any date on which the Fixed
   Rate Advance is prepaid, whether by acceleration or
   otherwise, and at maturity.  Interest accrued on each Fixed
   Rate Advance having an Interest Period longer than three
   months shall also be payable on the last day of each three-
   month interval during such Interest Period.  Interest on
   Fixed Rate Advances and commitment fees shall be calculated
   for actual days elapsed on the basis of a 360-day year and
   interest on Floating Rate Advances shall be calculated to
   actual days elapsed on the basis of a year of 365, or 366
   when appropriate, days.  Interest shall be payable for the
   day an Advance is made but not for the day of any payment on
   the amount paid if payment is received prior to noon (local
   time) at the place of payment.  If any payment of principal
   of or interest on an Advance shall become due on a day which
   is not a Business Day, such payment shall be made on the
   next succeeding Business Day and, in the case of a principal
   payment, such extension of time shall be included in
   computing interest in connection with such payment.

                                      13

   <PAGE>

        2.15.  Notification of Advances, Interest Rates,
   Prepayments and Commitment Reductions.  Promptly after
   receipt thereof, the Agent will notify each Lender of the
   contents of each Aggregate Commitment reduction notice,
   Borrowing Notice, Conversion/Continuation Notice, and
   repayment notice received by it hereunder.  The Agent will
   notify each Lender of the interest rate applicable to each
   Fixed Rate Advance and Floating Rate Advance promptly upon
   determination of such interest rate and will give each
   Lender and the Borrower prompt notice of each change in the
   Alternate Base Rate.

        2.16.  Lending Installations.  Each Lender may book
   its Loans at any Lending Installation selected by such
   Lender and may change its Lending Installation from time to
   time.  All terms of this Agreement shall apply to any such
   Lending Installation and the Notes shall be deemed held by
   each Lender for the benefit of such Lending Installation.
   Each Lender may, by written or telex notice to the Agent and
   the Borrower, designate a Lending Installation through which
   Loans will be made by it and for whose account Loan payments
   are to be made.

        2.17.  Non-Receipt of Funds by the Agent.  Unless the
   Borrower or a Lender, as the case may be, notifies the Agent
   prior to the date on which it is scheduled to make payment
   to the Agent of (i) in the case of a Lender, the proceeds of
   a Loan or (ii) in the case of the Borrower, a payment of
   principal, interest or fees to the Agent for the account of
   the Lenders, that it does not intend to make such payment,
   the Agent may assume that such payment has been made.  The
   Agent may, but shall not be obligated to, make the amount of
   such payment available to the intended recipient in reliance
   upon such assumption.  If such Lender or the Borrower, as
   the case may be, has not in fact made such payment to the
   Agent, the recipient of such payment shall, on demand by the
   Agent, repay to the Agent the amount so made available
   together with interest thereon in respect of each day during
   the period commencing on the date such amount was so made
   available by the Agent until the date the Agent recovers
   such amount at a rate per annum equal to (i) in the case of
   payment by a Lender, the Federal Funds Effective Rate for
   such day or (ii) in the case of payment by the Borrower, the
   interest rate applicable to the relevant Loan.

        2.18.  Withholding Tax Exemption. At least five
   Business Days prior to the first date on which interest or
   fees are payable hereunder for the account of any Lender,
   each Lender that is not incorporated under the laws of the
   United States of America, or a state thereof, agrees that it
   will deliver to each of the Borrower and the Agent two duly
   completed copies of United States Internal Revenue Service
   Form 1001 or 4224, certifying in either case that such
   Lender is entitled to receive payments under this Agreement
   and the Notes without deduction or withholding of any United
   States federal income taxes.  Each Lender which so delivers
   a Form 1001 or 4224 further undertakes to deliver to each of
   the Borrower and the Agent two additional copies of such
   form (or a successor form) on or before the date that such
   form expires (currently, three successive calendar years for
   Form 1001 and one calendar year for Form 4224) or becomes
   obsolete or after the occurrence of any event requiring a
   change in the most recent forms so delivered by it, and such
   amendments thereto or extensions or renewals thereof as may
   be reasonably requested by the Borrower or the Agent, in
   each case certifying that such Lender is entitled to receive
   payments under this Agreement and the Notes without
   deduction or withholding of any United States federal income
   taxes, unless an event (including without limitation any
   change in treaty, law or regulation) has occurred prior to
   the date on which any such delivery would otherwise be
   required which renders all such forms inapplicable or which

                                      14

   <PAGE>

   would prevent such Lender from duly completing and
   delivering any such form with respect to it and such Lender
   advises the Borrower and the Agent that it is not capable of
   receiving payments without any deduction or withholding of
   United States federal income tax.


                              ARTICLE III

                        CHANGE IN CIRCUMSTANCES

        3.1. Yield Protection.  If any law or any governmental
   or quasi-governmental rule, regulation, policy, guideline or
   directive (whether or not having the force of law), or any
   interpretation thereof, or the compliance of any Lender
   therewith,

             (i)  subjects any Lender or any applicable Lending
                  Installation to any tax, duty, charge or
                  withholding on or from payments due from the
                  Borrower (excluding federal taxation of the
                  overall net income of any Lender or
                  applicable Lending Installation), or changes
                  the basis of taxation of payments to any
                  Lender in respect of its Loans or other
                  amounts due it hereunder, or

             (ii) imposes or increases or deems applicable any
                  reserve, assessment, insurance charge,
                  special deposit or similar requirement
                  against assets of, deposits with or for the
                  account of, or credit extended by, any Lender
                  or any applicable Lending Installation (other
                  than reserves and assessments taken into
                  account in determining the interest rate
                  applicable to Fixed Rate Advances), or

             (iii)  imposes any other condition the result of
                  which is to increase the cost to any Lender
                  or any applicable Lending Installation of
                  making, funding or maintaining loans or
                  reduces any amount receivable by any Lender
                  or any applicable Lending Installation in
                  connection with loans, or requires any Lender
                  or any applicable Lending Installation to
                  make any payment calculated by reference to
                  the amount of loans held or interest received
                  by it, by an amount deemed material by such
                  Lender,

   then, within 15 days of demand by such Lender, the Borrower
   shall pay such Lender that portion of such increased expense
   incurred or reduction in an amount received which such
   Lender determines is attributable to making, funding and
   maintaining its Loans and its Commitment.

        3.2. Changes in Capital Adequacy Regulations.  If a
   Lender determines the amount of capital required or expected
   to be maintained by such Lender, any Lending Installation of
   such Lender or any corporation controlling such Lender is
   increased as a result of a Change, then, within 15 days of
   demand by such Lender, the Borrower shall pay such Lender
   the amount necessary to compensate for any shortfall in the
   rate of return on the portion of such increased capital
   which such Lender determines is attributable to this
   Agreement, its Loans or its obligation to make Loans
   hereunder (after taking into account such Lender's policies

                                      15

   <PAGE>

   as to capital adequacy).  "Change" means (i) any change
   after the date of this Agreement in the Risk-Based Capital
   Guidelines or (ii) any adoption of or change in any other
   law, governmental or quasi-governmental rule, regulation,
   policy, guideline, interpretation, or directive (whether or
   not having the force of law) after the date of this
   Agreement which affects the amount of capital required or
   expected to be maintained by any Lender or any Lending
   Installation or any corporation controlling any Lender.
   "Risk-Based Capital Guidelines" means (i) the risk-based
   capital guidelines in effect in the United States on the
   date of this Agreement, including transition rules, and (ii)
   the corresponding capital regulations promulgated by
   regulatory authorities outside the United States
   implementing the July 1988 report of the Basle Committee on
   Banking Regulation and Supervisory Practices Entitled
   "International Convergence of Capital Measurements and
   Capital Standards," including transition rules, and any
   amendments to such regulations adopted prior to the date of
   this Agreement.

        3.3. Availability of Types of Advances.  If any Lender
   determines that maintenance of any of its Fixed Rate Loans
   at a suitable Lending Installation would violate any
   applicable law, rule, regulation or directive, whether or
   not having the force of law, the Agent shall suspend the
   availability of the affected Type of Advance and require any
   Fixed Rate Advances of the affected Type to be repaid; or if
   the Required Lenders determine that (i) deposits of a type
   or maturity appropriate to match fund Fixed Rate Advances
   are not available, the Agent shall suspend the availability
   of the affected Type of Advance with respect to any Fixed
   Rate Advances made after the date of any such determination,
   or (ii) an interest rate applicable to a Type of Advance
   does not accurately reflect the cost of making a Fixed Rate
   Advance of such Type, then, if for any reason whatsoever the
   provisions of Section 3.1 are inapplicable, the Agent shall
   suspend the availability of the affected Type of Advance
   with respect to any Fixed Rate Advances made after the date
   of any such determination.  Subject to the provisions of
   Article II, the Borrower may select any unaffected rate
   option to apply to such affected Advances.  If the Borrower
   fails to select a new rate option, the affected Advances
   shall be Floating Rate Advances.

        3.4. Funding Indemnification.  If any payment of a
   Fixed Rate Advance occurs on a date which is not the last
   day of the applicable Interest Period, whether because of
   acceleration, prepayment or otherwise, or a Fixed Rate
   Advance is not made on the date specified by the Borrower
   for any reason other than default by the Lenders, the
   Borrower will indemnify each Lender for any loss or cost
   incurred by it resulting therefrom, including, without
   limitation, any loss or cost in liquidating or employing
   deposits acquired to fund or maintain the Fixed Rate
   Advance.

        3.5. Lender Statements; Survival of Indemnity. To the
   extent reasonably possible, each Lender shall designate an
   alternate Lending Installation with respect to its Fixed
   Rate Loans to reduce any liability of the Borrower to such
   Lender under Sections 3.1 and 3.2 or to avoid the
   unavailability of a Type of Advance under Section 3.3, so
   long as such designation is not disadvantageous to such
   Lender.  Each Lender shall deliver a written statement of
   such Lender as to the amount due, if any, under Sections
   3.1, 3.2 or 3.4.  Such written statement shall set forth in
   reasonable detail the calculations upon which such Lender
   determined such amount and shall be final, conclusive and
   binding on the Borrower in the absence of manifest error.
   Determination of amounts payable under such Sections in
   connection with a Fixed Rate Loan shall be calculated as
   though each Lender funded its Fixed Rate Loan through the
   purchase of a deposit of the type and maturity corresponding

                                      16

   <PAGE>

   to the deposit used as a reference in determining the Fixed
   Rate applicable to such Loan, whether in fact that is the
   case or not.  Unless otherwise provided herein, the amount
   specified in the written statement shall be payable on
   demand after receipt by the Borrower of the written
   statement.  The obligations of the Borrower under Sections
   3.1, 3.2 and 3.4 shall survive payment of the Obligations
   and termination of this Agreement.

        3.6. Election to Terminate.  If any Lender determines
   that a Fixed Rate Loan would violate any applicable law,
   rule, regulation or directive pursuant to Section 3.3 or any
   Lender (but not all the Lenders) has requested compensation
   pursuant to Sections 3.1 or 3.2, the Borrower may elect to
   replace such Lender ("Replaced Lender") with a substitute
   Lender ("Substitute Lender") with the prior written consent
   of the Agent, which consent shall not be unreasonably
   withheld.  If the Borrower elects to find a Substitute
   Lender, the Borrower shall give the Agent at least five
   Business Days' notice of the identity of such Substitute
   Lender.  On the sixth Business Day following receipt by the
   Agent of such notice, the Replaced Lender, upon receipt of
   payment in full of all of its outstanding Obligations, shall
   execute an assignment in the form of Exhibit "D" hereto of
   all of its rights and obligations under this Agreement to
   the Substitute Lender, except its right to indemnifications
   set forth in Section 9.7 hereof.

                  hereunder.

        4.2. Each Advance Which Increases Outstanding Advances.
   The Lenders shall not be required to make any Advance (other
   than an Advance that, after giving effect thereto and to the
   application of the proceeds thereof, does not increase the
   aggregate amount of outstanding Advances), unless on the
   applicable Borrowing Date:

             (i)  There exists no Default or Unmatured Default.

             (ii) The representations and warranties contained
                  in Article V are true and correct as of such

                  representation or warranty is stated to
                  relate solely to an earlier date, in which
                  case such representation or warranty shall be
                  true and correct on and as of such earlier
                  date.

                  of such Advance shall be satisfactory to the
                  Lenders and their counsel.

        Each Borrowing Notice with respect to each such Advance
   shall constitute a representation and warranty by the
   Borrower that the conditions contained in Sections 4.2(i)
   and (ii) have been satisfied.  Any Lender may require a duly
   completed compliance certificate in substantially the form
   of Exhibit "C" hereto as a condition to making an Advance.

        4.3. Each Advance Which Does Not Increase Outstanding
   Advances.  When the Borrower requests an Advance which,
   after giving effect thereto and to the application of the
   proceeds thereof, does not increase the aggregate amount of
   outstanding Advances, the Borrower shall represent to the
   Banks whether or not a Default exists.  A Borrowing Notice

                                      18

   <PAGE>

   delivered with respect to such an Advance shall constitute a
   representation that no Default exists.  If a Default exists,
   the requested Advance shall be made as a Floating Rate
   Advance.


                               ARTICLE V

                    REPRESENTATIONS AND WARRANTIES

        The Borrower represents and warrants to the Lenders
   that:

        5.1. Corporate Existence and Standing.  Each of the
   Borrower and its Subsidiaries is a corporation duly
   incorporated, validly existing and in good standing under
   the laws of its jurisdiction of incorporation and has all
   requisite authority to conduct its business in each
   jurisdiction in which its business is conducted except where
   the failure to have such authority would not have a Material
   Adverse Effect.

        5.2. Authorization and Validity.  The Borrower has the
   corporate power and authority and legal right to execute and
   deliver the Loan Documents and to perform its obligations
   thereunder.  The execution and delivery by the Borrower of
   the Loan Documents and the performance of its obligations
   thereunder have been duly authorized by proper corporate
   proceedings, and the Loan Documents constitute legal, valid
   and binding obligations of the Borrower enforceable against
   the Borrower in accordance with their terms, except as
   enforceability may be limited by bankruptcy, insolvency or
   similar laws affecting the enforcement of creditors' rights
   generally.

        5.3. No Conflict; Government Consent.  Neither the
   execution and delivery by the Borrower of the Loan
   Documents, nor the consummation of the transactions therein
   contemplated, nor compliance with the provisions thereof
   will violate any law, rule, regulation, order, writ,
   judgment, injunction, decree or award binding on the
   Borrower or any of its Subsidiaries, other than violations
   which would not have a Material Adverse Effect, or the
   Borrower's or any Subsidiary's articles or certificate of
   incorporation or by-laws or the provisions of any indenture,
   instrument or agreement to which the Borrower or any of its
   Subsidiaries is a party or is subject, or by which it, or
   its Property, is bound, or conflict with or constitute a
   default thereunder, or result in the creation or imposition
   of any Lien in, of or on the Property of the Borrower or a
   Subsidiary pursuant to the terms of any such indenture,
   instrument or agreement.  No order, consent, approval,
   license, authorization, or validation of, or filing,
   recording or registration with, or exemption by, any
   governmental or public body or authority, or any subdivision
   thereof, is required to authorize, or is required in
   connection with the execution, delivery and performance of,
   or the legality, validity, binding effect or enforceability
   of, any of the Loan Documents.

        5.4. Financial Statements.  The September 30, 1997,
   consolidated financial statements of the Borrower and its
   Subsidiaries heretofore delivered to the Lenders were
   prepared in accordance with generally accepted accounting
   principles in effect on the date such statements were
   prepared and fairly present the consolidated financial
   condition and operations of the Borrower and its

                                      19

   <PAGE>

   Subsidiaries at such date and the consolidated results of
   their operations for the period then ended.

        5.5. Material Adverse Change.  Since September 30, 1997
   there has been no change in the Borrower and its
   Subsidiaries which had a Material Adverse Effect.

        5.6. Taxes.  The Borrower and its Subsidiaries have
   filed all United States federal tax returns and all other
   tax returns which are required to be filed and have paid all
   taxes due pursuant to said returns or pursuant to any
   assessment received by the Borrower or any of its
   Subsidiaries, except such taxes, if any, as are being
   contested in good faith and as to which adequate reserves
   have been provided in accordance with GAAP.  The United
   States income tax returns of the Borrower and its
   Subsidiaries have been audited by the Internal Revenue
   Service through the fiscal year ended December 31, 1990.  No
   tax liens have been filed and no claims are being asserted
   with respect to any such taxes except as permitted under
   Section 6.16(i) below.  The Borrower does not know of any
   proposed additional tax assessment against it for which
   adequate provisions has not been made on its accounts.  The
   charges, accruals and reserves on the books of the Borrower
   and its Subsidiaries in respect of any taxes or other
   governmental charges are adequate.

        5.7. Litigation and Contingent Obligations.  Except as
   set forth on Schedule "3" hereto, there is no litigation,
   arbitration, governmental investigation, proceeding or
   inquiry pending or, to the knowledge of any of their
   officers, threatened against or affecting the Borrower or
   any of its Subsidiaries which, if adversely determined,
   could reasonably be expected to have a Material Adverse
   Effect.  Other than any liability incident to such
   litigation, arbitration or proceedings, the Borrower has no
   material contingent obligations not provided for or
   disclosed in the financial statements referred to in Section
   5.4.

        5.8. Subsidiaries.  Schedule "1" hereto contains an
   accurate list of all of the presently existing Subsidiaries
   of the Borrower, setting forth their respective
   jurisdictions of incorporation and the percentage of their
   respective capital stock owned by the Borrower or other
   Subsidiaries.  All of the issued and outstanding shares of
   capital stock of such Subsidiaries have been duly authorized
   and issued and are fully paid and non-assessable.

        5.9. ERISA.  There are no Unfunded Liabilities under
   any Single Employer Plan.  Each Plan complies in all
   material respects with all applicable requirements of law
   and regulations and no Reportable Event has occurred and is
   ongoing with respect to any Plan.  Since September 30, 1997,
   neither the Borrower nor any other members of the Controlled
   Group has withdrawn from any Plan or initiated steps to do
   so, and no steps have been taken to reorganize or terminate
   any Plan.

        5.10.  Accuracy of Information.  No information,
   exhibit or report furnished by the Borrower or any of its
   Subsidiaries to the Agent or to any Lender in connection
   with the negotiation of, or compliance with, the Loan
   Documents contained any material misstatement of fact or
   omitted to state a material fact or any fact necessary to
   make the statements contained therein not misleading.

        5.11.  Regulation U.  Margin stock (as defined in
   Regulation U) constitutes less than 25% of those assets
   of the Borrower and its Subsidiaries which are subject to
   any limitation on sale, pledge, or other restriction
   hereunder.

        5.12.  Material Agreements.  Neither the Borrower nor
   any Subsidiary is a party to any agreement or instrument or
   subject to any charter or other corporate restriction which
   would have a Material Adverse Effect.  Neither the Borrower
   nor any Subsidiary is in default in the performance,
   observance or fulfillment of any of the obligations,
   covenants or conditions contained in (i) any agreement to
   which it is a party, which default would have a Material
   Adverse Effect or (ii) any agreement or instrument
   evidencing or governing any Major Indebtedness.

        5.13.  Compliance With Laws.  Neither the Borrower nor
   any Subsidiary (a) is in violation of any law, ordinance,
   franchise, governmental rule and/or regulation to which it
   is subject; (b) is in default with respect to any order of
   any court or governmental authority or arbitration board or
   tribunal; and/or (c) has failed to obtain any license,
   permit, franchise and/or other governmental authorization
   necessary to the ownership of its Property and/or to the
   conduct of its business, which violation, default and/or
   failure to obtain would have a Material Adverse Effect.

        5.14.  Compliance with Environmental Law.  Except
   where any such violation would not have a Material Adverse
   Effect, the Borrower and its Subsidiaries are not in
   violation of any applicable Federal, state and/or local
   laws, statutes, rules, regulations and/or ordinances
   relating to public health, safety and/or the environment
   including, without limitation, those relating (a) to
   releases, discharges, emissions and/or disposal into air,
   water, land and/or groundwater, (b) to the withdrawal and/or
   use of groundwater, (c) to the uses, of handling and/or
   disposal of polychlorinated biphenyls and/or asbestos, (d)
   to the disposal, treatment, storage and/or management of
   hazardous or solid waste, and/or Hazardous Substances and/or
   crude oil, fractious petroleum derivatives and/or by-
   products thereof, (e) to exposure to toxic and/or hazardous
   materials, (f) to the handling, transportation, discharge
   and/or release of gaseous and/or liquid Hazardous Substances
   ("Environmental Laws"), and any order, notice and/or demand
   issued pursuant to such Environmental Laws, in each case
   applicable to the Property of the Borrower and its
   Subsidiaries and/or the operation and/or modification
   thereof.

        5.15.  Ownership of Properties.  Except as set forth
   on Schedule "2" hereto, on the date of this Agreement, the
   Borrower and its Subsidiaries have good title (except for
   immaterial defects of title), free of all Liens other than
   those permitted by Section 6.16, to all of the Property and
   assets reflected in the financial statements referred to in
   Section 5.4 as owned by it, except as sold and/or otherwise
   disposed of in the ordinary course of business.

        5.16.  Patents and Trademarks. The Borrower and each
   Subsidiary (i) owns and/or possesses all the patents,
   trademarks, trade names, service marks, copyrights, licenses
   and rights with respect to the foregoing necessary for the
   present conduct of its business without any known conflict
   with the rights of others, and (ii) owns and/or possesses
   and/or has applied for all the patents, trademarks, trade
   names, service marks, copyrights, licenses and rights with
   respect to the foregoing necessary for the planned conduct
   of its business for the next six months, without any known

                                      21
   <PAGE>

   conflict with the rights of others, except, with respect to
   clauses (i) and (ii), where the failure to own and/or
   possess any patents, trademarks, trade names, service marks,
   copyrights, licenses and/or rights would not have a Material
   Adverse Effect on the Borrower and its Subsidiaries, taken
   as a whole, and/or subject the Borrower to any material
   liability in connection with any infringement and/or similar
   cause of action related to any of the foregoing.

        5.17.  Investment Company Act.  Neither the Borrower
   nor any Subsidiary thereof is an "investment company" or a
   company "controlled" by an "investment company", within the
   meaning of the Investment Company Act of 1940, as amended.

        5.18.  Public Utility Holding Company Act.  Neither

   of the Lenders or the Agent to exercise any right under the

   a waiver of any Default or an acquiescence therein, and the
   making of a Loan notwithstanding the existence of a Default
   or the inability of the Borrower to satisfy the conditions
   precedent to such Loan shall not constitute any waiver or
   acquiescence.  Any single or partial exercise of any such
   right shall not preclude other or further exercise thereof
   or the exercise of any other right, and no waiver, amendment
   or other variation of the terms, conditions or provisions of
   the Loan Documents whatsoever shall be valid unless in
   writing signed by the Lenders required pursuant to Section
   8.2, and then only to the extent in such writing
   specifically set forth.  All remedies contained in the Loan
   Documents or by law afforded shall be cumulative and all
   shall be available to the Agent and the Lenders until the
   Obligations have been paid in full.

                          GENERAL PROVISIONS

        9.1. Survival of Representations.  All representations
   and warranties of the Borrower contained in this Agreement
   shall survive delivery of the Notes and the making of the
   Loans herein contemplated.

        9.2. Governmental Regulation.  Anything contained in
   this Agreement to the contrary notwithstanding, no Lender
   shall be obligated to extend credit to the Borrower in
   violation of any limitation or prohibition provided by any
   applicable statute or regulation.

        9.3. Taxes.  Any taxes (excluding federal income taxes
   on the overall net income of any Lender) or other similar
   assessments or charges made by any governmental or revenue
   authority in respect of the Loan Documents shall be paid by
   the Borrower, together with interest and penalties, if any.

        9.4. Headings.  Section headings in the Loan Documents
   are for convenience of reference only, and shall not govern
   the interpretation of any of the provisions of the Loan
   Documents.

        9.5. Entire Agreement.  The Loan Documents embody the
   entire agreement and understanding among the Borrower, the
   Agent and the Lenders and supersede all prior agreements and
   understandings among the Borrower, the Agent and the Lenders
   relating to the subject matter thereof other than the fee
   letter described in Section 10.13.

        9.6. Several Obligations; Benefits of this Agreement.
   The respective obligations of the Lenders hereunder are
   several and not joint and no Lender shall be the partner or
   agent of any other (except to the extent to which the Agent
   is authorized to act as such).  The failure of any Lender to
   perform any of its obligations hereunder shall not relieve
   any other Lender from any of its obligations hereunder.
   This Agreement shall not be construed so as to confer any
   right or benefit upon any Person other than the parties to
   this Agreement and their respective successors and assigns.

        9.7. Expenses; Indemnification.  The Borrower shall
   reimburse the Agent for any costs, internal charges and out-
   of-pocket expenses (including attorneys' fees and time
   charges of attorneys for the Agent, which attorneys may be
   employees of the Agent) paid or incurred by the Agent in
   connection with the preparation, negotiation, execution,
   delivery, review, amendment, modification, and
   administration of the Loan Documents.  The Borrower also
   agrees to reimburse the Agent and the Lenders for any costs,
   internal charges and out-of-pocket expenses (including
   attorneys' fees and time charges of attorneys for the Agent
   and the Lenders, which attorneys may be employees of the
   Agent or the Lenders) paid or incurred by the Agent or any
   Lender in connection with the collection and enforcement of
   the Loan Documents. The Borrower further agrees to indemnify
   the Agent and each Lender, its directors, officers and
   employees against all losses, claims, damages, penalties,
   judgments, liabilities and expenses (including, without
   limitation, all expenses of litigation or preparation

                                      31

   <PAGE>

   therefor whether or not the Agent or any Lender is a party
   thereto) which any of them may pay or incur arising out of
   or relating to this Agreement, the other Loan Documents, the
   transactions contemplated hereby or the direct or indirect
   application or proposed application of the proceeds of any
   Loan hereunder (other than these resulting from the bad
   faith, gross negligence or willful misconduct of any Lender
   or the Agent.)  The obligations of the Borrower under this
   Section shall survive the termination of this Agreement.

        9.8. Numbers of Documents.  All statements, notices,
   closing documents, and requests hereunder shall be furnished
   to the Agent with sufficient counterparts so that the Agent
   may furnish one to each of the Lenders.

        9.9. Accounting.  Except as provided to the contrary
   herein, all accounting terms used herein shall be
   interpreted and all accounting determinations hereunder
   shall be made in accordance with GAAP.

        9.10.  Severability of Provisions.  Any provision in
   any Loan Document that is held to be inoperative,
   unenforceable, or invalid in any jurisdiction shall, as to
   that jurisdiction, be inoperative, unenforceable, or invalid
   without affecting the remaining provisions in that
   jurisdiction or the operation, enforceability, or validity
   of that provision in any other jurisdiction, and to this end
   the provisions of all Loan Documents are declared to be
   severable.

        9.11.  Nonliability of Lenders.  The relationship
   between the Borrower and the Lenders and the Agent shall be
   solely that of borrower and lender.  Neither the Agent nor
   any Lender shall have any fiduciary responsibilities to the
   Borrower.  Neither the Agent nor any Lender undertakes any
   responsibility to the Borrower to review or inform the
   Borrower of any matter in connection with any phase of the
   Borrower's business or operations.

        9.12.  CHOICE OF LAW.  THE LOAN DOCUMENTS (OTHER THAN
   THOSE CONTAINING A CONTRARY EXPRESS CHOICE OF LAW PROVISION)
   SHALL BE CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS (AND
   NOT THE LAW OF CONFLICTS) OF THE STATE OF ILLINOIS, BUT
   GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

        9.13.  CONSENT TO JURISDICTION.  THE BORROWER HEREBY
   IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY
   UNITED STATES FEDERAL OR ILLINOIS STATE COURT SITTING IN
   CHICAGO IN ANY ACTION OR PROCEEDING ARISING OUT OF OR
   RELATING TO ANY LOAN DOCUMENTS AND THE BORROWER HEREBY
   IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION
   OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT
   AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER
   HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING
   BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN
   INCONVENIENT FORUM.  NOTHING HEREIN SHALL LIMIT THE RIGHT OF
   THE AGENT OR ANY LENDER TO BRING PROCEEDINGS AGAINST THE
   BORROWER IN THE COURTS OF ANY OTHER JURISDICTION.  ANY
   JUDICIAL PROCEEDING BY THE BORROWER AGAINST THE AGENT OR ANY

                                      32

   <PAGE>

   LENDER OR ANY AFFILIATE OF THE AGENT OR ANY LENDER
   INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY
   ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN
   DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN CHICAGO,
   ILLINOIS.

        9.14.  WAIVER OF JURY TRIAL.  THE BORROWER, THE AGENT
   AND EACH LENDER HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL
   PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER
   (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY
   ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN
   DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER.


                               ARTICLE X

                               THE AGENT

        10.1.  Appointment; Nature of Relationship.  The First
   National Bank of Chicago is hereby appointed by the Lenders
   as Agent hereunder and under each other Loan Document, and
   each of the Lenders irrevocably authorizes the Agent to act
   as the contractual representative of such Lender with the
   rights and duties expressly set forth herein and in the
   other Loan Documents.  The Agent agrees to act as such
   contractual representative upon the express conditions
   contained in this Article X.  Notwithstanding the use of the
   defined term "Agent," it is expressly understood and agreed
   that the Agent shall not have any fiduciary responsibilities
   to any Lender by reason of this Agreement or any other Loan
   Document and that the Agent is merely acting as the
   representative of the Lenders with only those duties as are
   expressly set forth in this Agreement and the other Loan
   Documents.  In its capacity as the Lenders' contractual
   representative, the Agent (i) does not hereby assume any
   fiduciary duties to any of the Lenders, (ii) is a
   "representative" of the Lenders within the meaning of
   Section 9-105 of the Uniform Commercial Code and (iii) is
   acting as an independent contractor, the rights and duties
   of which are limited to those expressly set forth in this
   Agreement and the other Loan Documents.  Each of the Lenders
   hereby agrees to assert no claim against the Agent on any
   agency theory or any other theory of liability for breach of
   fiduciary duty, all of which claims each Lender hereby
   waives.

        10.2.  Powers.  The Agent shall have and may exercise
   such powers under the Loan Documents as are specifically
   delegated to the Agent by the terms of each thereof,
   together with such powers as are reasonably incidental
   thereto.  The Agent shall have no implied duties to the
   Lenders, or any obligation to the Lenders to take any action
   thereunder except any action specifically provided by the
   Loan Documents to be taken by the Agent.

        10.3.  General Immunity.  Neither the Agent nor any of
   its directors, officers, agents or employees shall be liable
   to the Borrower, the Lenders or any Lender for any action
   taken or omitted to be taken by it or them hereunder or
   under any other Loan Document or in connection herewith or
   therewith except for its or their own gross negligence or
   willful misconduct.

                                      33

   <PAGE>

        10.4.  No Responsibility for Loans, Recitals, etc.
   Neither the Agent nor any of its directors, officers, agents
   or employees shall be responsible for or have any duty to
   ascertain, inquire into, or verify (i) any statement,
   warranty or representation made in connection with any Loan
   Document or any borrowing hereunder; (ii) the performance or
   observance of any of the covenants or agreements of any
   obligor under any Loan Document, including, without
   limitation, any agreement by an obligor to furnish
   information directly to each Lender; (iii) the satisfaction
   of any condition specified in Article IV, except receipt of
   items required to be delivered to the Agent; or (iv) the
   validity, enforceability, effectiveness, sufficiency or
   genuineness of any Loan Document or any other instrument or
   writing furnished in connection therewith.  The Agent shall
   have no duty to disclose to the Lenders information that is
   not required to be furnished by the Borrower to the Agent at
   such time, but is voluntarily furnished by the Borrower to
   the Agent in its individual capacity.  No Lender shall have
   any duty to disclose to the Agent or the other Lenders
   information voluntarily furnished by the Borrower to such
   Lender in its individual capacity.

        10.5.  Action on Instructions of Lenders.  The Agent
   shall in all cases be fully protected in acting, or in
   refraining from acting, hereunder and under any other Loan
   Document in accordance with written instructions signed by
   the Required Lenders, and such instructions and any action
   taken or failure to act pursuant thereto shall be binding on
   all of the Lenders and on all holders of Notes.  The Lenders
   hereby acknowledge that the Agent shall be under no duty to
   take any discretionary action permitted to be taken by it
   pursuant to the provisions of this Agreement or any other
   Loan Document unless it shall be requested in writing to do
   so by the Required Lenders.  The Agent shall be fully
   justified in failing or refusing to take any action
   hereunder and under any other Loan Document unless it shall
   first be indemnified to its satisfaction by the Lenders pro
   rata against any and all liability, cost and expense that it
   may incur by reason of taking or continuing to take any such
   action.

        10.6.  Employment of Agents and Counsel.  The Agent
   may execute any of its duties as Agent hereunder and under
   any other Loan Document by or through employees, agents, and
   attorneys-in-fact and shall not be answerable to the
   Lenders, except as to money or securities received by it or
   its authorized agents, for the default or misconduct of any
   such agents or attorneys-in-fact selected by it with
   reasonable care.  The Agent shall be entitled to advice of
   counsel concerning all matters pertaining to the agency
   hereby created and its duties hereunder and under any other
   Loan Document.

        10.7.  Reliance on Documents; Counsel.  The Agent
   shall be entitled to rely upon any Note, notice, consent,
   certificate, affidavit, letter, telegram, statement, paper
   or document believed by it to be genuine and correct and to
   have been signed or sent by the proper person or persons,
   and, in respect to legal matters, upon the opinion of
   counsel selected by the Agent, which counsel may be
   employees of the Agent.

        10.8.  Agent's Reimbursement and Indemnification.  The
   Lenders agree to reimburse and indemnify the Agent ratably
   in proportion to their respective Commitments (or, if the
   Commitments have been terminated, in proportion to their
   Commitments immediately prior to such termination) (i) for
   any amounts not reimbursed by the Borrower for which the
   Agent is entitled to reimbursement by the Borrower under the
   Loan Documents, (ii) for any other expenses incurred by the

                                      34

   <PAGE>

   Agent on behalf of the Lenders and not reimbursed by the
   Borrower, in connection with the preparation, execution,
   delivery, administration and enforcement of the Loan
   Documents and (iii) for any liabilities, obligations,
   losses, damages, penalties, actions, judgments, suits,
   costs, expenses or disbursements of any kind and nature
   whatsoever which are not reimbursed by the Borrower and
   which may be imposed on, incurred by or asserted against the
   Agent in any way relating to or arising out of the Loan
   Documents or any other document delivered in connection
   therewith or the transactions contemplated thereby, or the
   enforcement of any of the terms thereof or of any such other
   documents, provided that no Lender shall be liable for any
   of the foregoing to the extent they arise from the gross
   negligence or willful misconduct of the Agent.  If the Agent
   later receives any such amount from the Borrower it will
   reimburse the Lenders for any applicable amounts paid under
   this Section 10.8.  The obligations of the Lenders under
   this Section 10.8 shall survive payment of the Obligations
   and termination of this Agreement.

        10.9.  Rights as a Lender.  In the event the Agent is
   a Lender, the Agent shall have the same rights and powers
   hereunder and under any other Loan Document as any Lender
   and may exercise the same as though it were not the Agent,
   and the term "Lender" or "Lenders" shall, at any time when
   the Agent is a Lender, unless the context otherwise
   indicates, include the Agent in its individual capacity.
   The Agent may accept deposits from, lend money to, and
   generally engage in any kind of trust, debt, equity or other
   transaction, in addition to those contemplated by this
   Agreement or any other Loan Document, with the Borrower or
   any of its Subsidiaries in which the Borrower or such
   Subsidiary is not restricted hereby from engaging with any
   other Person.  The Agent, in its individual capacity, is not
   obligated to remain a Lender.

        10.10. Lender Credit Decision.  Each Lender
   acknowledges that it has, independently and without reliance
   upon the Agent or any other Lender and based on the
   financial statements prepared by the Borrower and such other
   documents and information as it has deemed appropriate, made
   its own credit analysis and decision to enter into this
   Agreement and the other Loan Documents.  Each Lender also
   acknowledges that it will, independently and without
   reliance upon the Agent or any other Lender and based on
   such documents and information as it shall deem appropriate
   at the time, continue to make its own credit decisions in
   taking or not taking action under this Agreement and the
   other Loan Documents.

        10.11. Successor Agent.  The Agent may resign at any
   time by giving written notice thereof to the Lenders and the
   Borrower, such resignation to be effective upon the
   appointment of a successor Agent or, if no successor Agent
   has been appointed, forty-five days after the retiring Agent
   gives notice of its intention to resign.  The Agent may be
   removed at any time with or without cause by written notice
   received by the Agent from the Required Lenders, such
   removal to be effective on the date specified by the
   Required Lenders.  Upon any such resignation or removal, the
   Required Lenders shall have the right to appoint, on behalf
   of the Borrower and the Lenders, a successor Agent.  If no
   successor Agent shall have been so appointed by the Required
   Lenders within thirty days after the resigning Agent's
   giving notice of its intention to resign, then the resigning
   Agent may appoint, on behalf of the Borrower and the
   Lenders, a successor Agent.  If the Agent has resigned or
   been removed and no successor Agent has been appointed, the
   Lenders may perform all the duties of the Agent hereunder
   and the Borrower shall make all payments in respect of the
   Obligations to the applicable Lender and for all other

                                      35

   <PAGE>

   purposes shall deal directly with the Lenders.  No successor
   Agent shall be deemed to be appointed hereunder until such
   successor Agent has accepted the appointment.  Any such
   successor Agent shall be a commercial bank having capital
   and retained earnings of at least $50,000,000.  Upon the
   acceptance of any appointment as Agent hereunder by a
   successor Agent, such successor Agent shall thereupon
   succeed to and become vested with all the rights, powers,
   privileges and duties of the resigning or removed Agent.
   Upon the effectiveness of the resignation or removal of the
   Agent, the resigning or removed Agent shall be discharged
   from its duties and obligations hereunder and under the Loan
   Documents.  After the effectiveness of the resignation or
   removal of an Agent, the provisions of this Article X shall
   continue in effect for the benefit of such Agent in respect
   of any actions taken or omitted to be taken by it while it
   was acting as the Agent hereunder and under the other Loan
   Documents.

        10.12. Agent's Fees.  The Borrower agrees to pay to
   the Agent, for its own account, the fees pursuant to that
   certain fee letter dated April 7, 1998 between the Borrower
   and the Arranger, or as otherwise agreed from time to time.

        10.13. Notice of Default.  The Agent shall not be
   deemed to have knowledge or notice of the occurrence of any
   Default or Unmatured Default hereunder unless the Agent has
   received written notice from a Lender or the Borrower
   referring to this Agreement describing such Default or
   unmatured Default and stating that such notice is a "notice
   of default".  In the event that the Agent receives such a
   notice, the Agent shall give prompt notice thereof to the
   Lenders and the Borrower.


                              ARTICLE XI

                       SETOFF; RATABLE PAYMENTS

        11.1.  Setoff.  In addition to, and without limitation
   of, any rights of the Lenders under applicable law, if the
   Borrower becomes insolvent, however evidenced, or any
   Default occurs, any and all deposits (including all account
   balances, whether provisional or final and whether or not
   collected or available) and any other Indebtedness at any
   time held or owing by any Lender to or for the credit or
   account of the Borrower may be offset and applied toward the
   payment of the Obligations owing to such Lender, whether or
   not the Obligations, or any part hereof, shall then be due.

        11.2.  Ratable Payments.  If any Lender, whether by
   setoff or otherwise, has payment made to it upon its Loans
   (other than payments received pursuant to Sections 3.1, 3.2
   or 3.4) in a greater proportion than that received by any
   other Lender, such benefitted Lender agrees, promptly upon
   demand, to purchase a portion of the Loans held by the other
   Lenders so that after such purchase each Lender will hold
   its ratable proportion of Loans.  If any Lender, whether in
   connection with setoff or amounts which might be subject to
   setoff or otherwise, receives collateral or other protection
   for its Obligations or such amounts which may be subject to
   setoff, such benefitted Lender agrees, promptly upon demand,
   to take such action necessary such that all Lenders share in
   the benefits of such collateral ratably in proportion to
   their Loans.  If all or any portion of such excess payment
   or benefits is thereafter recovered from such benefitted

                                      36

   <PAGE>

   Lender, such purchase shall be rescinded, and the purchase
   price and benefits returned, to the extent of such recovery
   but without interest.


                              ARTICLE XII

           BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

        12.1.  Successors and Assigns.  The terms and
   provisions of the Loan Documents shall be binding upon and
   inure to the benefit of the Borrower and the Lenders and
   their respective successors and assigns, except that (i) the
   Borrower shall not have the right to assign its rights or
   obligations under the Loan Documents and (ii) any assignment
   by any Lender must be made in compliance with Section 12.3.
   Notwithstanding clause (ii) of this Section, any Lender may
   at any time, without the consent of the Borrower or the
   Agent, assign all or any portion of its rights under this
   Agreement and its Notes to a Federal Reserve Bank; provided,
   however, that no such assignment shall release the
   transferor Lender from its obligations hereunder.  The Agent
   may treat the payee of any Note as the owner thereof for all
   purposes hereof unless and until such payee complies with
   Section 12.3 in the case of an assignment thereof or, in the
   case of any other transfer, a written notice of the transfer
   is filed with the Agent.  Any assignee or transferee of a
   Note agrees by acceptance thereof to be bound by all the
   terms and provisions of the Loan Documents.  Any request,
   authority or consent of any Person, who at the time of
   making such request or giving such authority or consent is
   the holder of any Note, shall be conclusive and binding on
   any subsequent holder, transferee or assignee of such Note
   or of any Note or Notes issued in exchange therefor.

        12.2.  Participations.

             12.2.1.Permitted Participants; Effect.  Any
   Lender may, in the ordinary course of its business and in
   accordance with applicable law, at any time sell to one or
   more banks or other entities ("Participants") participating
   interests in any Loan owing to such Lender, any Note held by
   such Lender, any Commitment of such Lender or any other
   interest of such Lender under the Loan Documents.  In the
   event of any such sale by a Lender of participating
   interests to a Participant, such Lender's obligations under
   the Loan Documents shall remain unchanged, such Lender shall
   remain solely responsible to the other parties hereto for
   the performance of such obligations, such Lender shall
   remain the holder of any such Note for all purposes under
   the Loan Documents, all amounts payable by the Borrower
   under this Agreement shall be determined as if such Lender
   had not sold such participating interests, and the Borrower
   and the Agent shall continue to deal solely and directly
   with such Lender in connection with such Lender's rights and
   obligations under the Loan Documents.

             12.2.2.Voting Rights.  Each Lender shall retain
   the sole right to approve, without the consent of any
   Participant, any amendment, modification or waiver of any
   provision of the Loan Documents other than any amendment,
   modification or waiver with respect to any Loan or
   Commitment in which such Participant has an interest which
   forgives principal, interest or fees or reduces the interest
   rate or fees payable with respect to any such Loan or
   Commitment, postpones any date fixed for any
   regularly-scheduled payment of principal of, or interest or

                                      37

   <PAGE>


   fees on, any such Loan or Commitment, releases any guarantor
   of any such Loan or releases any substantial portion of
   collateral, if any, securing any such Loan.

             12.2.3.Benefit of Setoff.  The Borrower agrees
   that each Participant shall be deemed to have the right of
   setoff provided in Section 11.1 in respect of its
   participating interest in amounts owing under the Loan
   Documents to the same extent as if the amount of its
   participating interest were owing directly to it as a Lender
   under the Loan Documents, provided that each Lender shall
   retain the right of setoff provided in Section 11.1 with
   respect to the amount of participating interests sold to
   each Participant.  The Lenders agree to share with each
   Participant, and each Participant, by exercising the right
   of setoff provided in Section 11.1, agrees to share with
   each Lender, any amount received pursuant to the exercise of
   its right of setoff, such amounts to be shared in accordance
   with Section 11.2 as if each Participant were a Lender.

        12.3.  Assignments.

             12.3.1.Permitted Assignments.  Any Lender may, in
   the ordinary course of its business and in accordance with
   applicable law, at any time assign to one or more banks or
   other entities ("Purchasers") all or any part of its rights
   and obligations under the Loan Documents, provided that any
   such assignment shall be in a minimum amount of
   $5,000,000.  Such assignment shall be substantially in the
   form of Exhibit "D" hereto or in such other form as may be
   agreed to by the parties thereto.  The consent of the
   Borrower and the Agent shall be required prior to an
   assignment becoming effective with respect to a Purchaser
   which is not a Lender or an Affiliate thereof; provided,
   however, that if a Default has occurred and is continuing,
   the consent of the Borrower shall not be required.  Such
   consent shall not be unreasonably withheld.

             12.3.2.Effect; Effective Date.  Upon (i) delivery
   to the Agent of a notice of assignment, substantially in the
   form attached as Exhibit "I" to Exhibit "D" hereto (a
   "Notice of Assignment"), together with any consents required
   by Section 12.3.1, and (ii) payment of a $3,500 fee by
   the assignor or the assignee to the Agent for processing
   such assignment, such assignment shall become effective on
   the effective date specified in such Notice of Assignment.
   The Notice of Assignment shall contain a representation by
   the Purchaser to the effect that none of the consideration
   used to make the purchase of the Commitment and Loans under
   the applicable assignment agreement are "plan assets" as
   defined under ERISA and that the rights and interests of the
   Purchaser in and under the Loan Documents will not be "plan
   assets" under ERISA.  On and after the effective date of
   such assignment, such Purchaser shall for all purposes be a
   Lender party to this Agreement and any other Loan Document
   executed by the Lenders and shall have all the rights and
   obligations of a Lender under the Loan Documents, to the
   same extent as if it were an original party hereto, and no
   further consent or action by the Borrower, the Lenders or
   the Agent shall be required to release the transferor Lender
   with respect to the percentage of the Aggregate Commitment
   and Loans assigned to such Purchaser.  Upon the consummation
   of any assignment to a Purchaser pursuant to this Section
   12.3.2, the transferor Lender, the Agent and the Borrower
   shall make appropriate arrangements so that replacement
   Notes are issued to such transferor Lender and new Notes or,
   as appropriate, replacement Notes, are issued to such
   Purchaser, in each case in principal amounts reflecting
   their Commitment, as adjusted pursuant to such assignment.

        12.4.  Dissemination of Information.  The Borrower
   authorizes each Lender to disclose to any Participant or
   Purchaser or any other Person acquiring an interest in the
   Loan Documents by operation of law (each a "Transferee") and
   any prospective Transferee any and all information in such
   Lender's possession concerning the creditworthiness of the
   Borrower and its Subsidiaries provided such Transferee has
   executed a confidentiality agreement in the form of Exhibit
   "F" hereto.

        12.5.  Tax Treatment.  If any interest in any Loan
   Document is transferred to any Transferee which is organized
   under the laws of any jurisdiction other than the United
   States or any State thereof, the transferor Lender shall
   cause such Transferee, concurrently with the effectiveness
   of such transfer, to comply with the provisions of Section
   2.18.


                             ARTICLE XIII

                                NOTICES

        13.1.  Giving Notice.  Except as otherwise permitted
   by Section 2.13 with respect to borrowing notices, all
   notices and other communications provided to any party
   hereto under this Agreement or any other Loan Document shall
   be in writing or by telex or by facsimile and addressed or
   delivered to such party at its address set forth below its
   signature hereto or at such other address as may be
   designated by such party in a notice to the other parties.
   Any notice, if mailed and properly addressed with postage
   prepaid, 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).

        13.2.  Change of Address.  The Borrower, the Agent and
   any Lender may each change the address for service of notice
   upon it by a notice in writing to the other parties hereto.


                              ARTICLE XIV

                             COUNTERPARTS

        This Agreement may be executed in any number of
   counterparts, all of which taken together shall constitute
   one agreement, and any of the parties hereto may execute
   this Agreement by signing any such counterpart.  This
   Agreement shall be effective when it has been executed by
   the Borrower, the Agent and the Lenders and each party has
   notified the Agent by telex or telephone, that it has taken
   such action.

                                            _______________, 19__
   [Names of Lenders]
   c/o The First National Bank of Chicago,
     as Agent
   One First National Plaza
   Chicago, Illinois 60670

   Gentlemen/Ladies:

        I am the General counsel for Bio-Rad Laboratories,
   Inc., a Delaware corporation (the "Borrower").  I understand
   that you and the Borrower have entered into a Credit
   Agreement dated as of May 15, 1998 (the "Agreement").
   Although I have not participated in the preparation or
   negotiation of the Agreement, I have reviewed the Agreement
   and am familiar with its terms and conditions.  The Borrower
   has requested that I furnish this opinion to you pursuant to
   section 4.1 (vii) of the Agreement.  Capitalized terms used
   herein and not otherwise defined shall have the meanings
   ascribed to them in the Agreement.

        I have been furnished and have examined originals, or
   copies certified or otherwise identified to our satisfaction
   as being true copies of the originals, of such records of
   the Borrower, agreements and other instruments, certificates
   of officers, agents and representatives of the Borrower,
   certificates of public officials and other documents as I
   have deemed necessary as a basis for the opinions
   hereinafter expressed.  In addition, I assume that none of
   the Lenders has waived or released any of its rights or
   remedies under the Agreement or is estopped from asserting
   or maintaining any of the same and that no breach of or
   default under the Agreement has occurred or is continuing.
   Based on the foregoing, I am of the opinion that:

        1. The Borrower is duly incorporated, validly existing and in
   good standing as a corporation under the laws of the State of
   Delaware.  The Borrower is duly qualified and in good standing as
   a foreign corporation in each jurisdiction in which the character
   or location of its properties (owned, leased or licensed) or the
   nature or conduct of its business makes such qualification
   necessary, except for those failures to be so qualified or in
   good standing which will not in the aggregate have a material
   adverse effect on the Borrower and its Subsidiaries taken as a
   whole.  The Borrower has all requisite corporate authority to
   own, lease and license its properties and conduct its business as
   now being conducted.

        2. The execution and delivery of the Loan Documents by the
   Borrower and the performance by the Borrower of the Obligations
   have been duly authorized by all necessary corporate actions and
   proceedings on the part of the Borrower and will not:

        (a)  require any consent of the Borrower's stockholders,

                                      44

   <PAGE>

        (b)  violate any order, writ, judgment, injunction, decree or
   award known to me after reasonable inquiry and binding on the
   Borrower, or any law, rule or regulation binding on the Borrower,
   or the Borrower's Certificate of Incorporation or By-laws, or any
   material indenture, instrument or agreement know to me after
   reasonable inquiry and binding on the Borrower; or

        (c)  result in, or require, the creation or imposition of any
   Lien pursuant to any material indenture, instrument or agreement
   known to me after reasonable inquiry and binding on the Borrower.

        3. The Loan Documents have been duly executed and delivered by
   the Borrower and constitute legally, valid and binding
   obligations of the Borrower enforceable in accordance with their
   respective terms, except (a) as may be limited by bankruptcy,
   insolvency, moratorium, reorganization or similar laws affecting
   creditors rights generally, and (b) that the remedies of specific
   performance and injunction and other forms of equitable relief,
   and the enforceability of sections 9.12 and 9.13 of the Agreement
   (relating to choice of law and choice of forum), are subject to
   equitable and other defenses and to the discretion of the court
   before which any proceedings therefor may be brought.

        4. To the best of my knowledge after reasonable inquiry, there
   is no litigation or proceeding against the Borrower which, if
   adversely  determined, would materially and adversely affect the
   business or condition of the Borrower and its Subsidiaries taken
   as a whole.

        5. No approval, authorization, consent, adjudication or order
   of any governmental authority which has not been obtained by the
   Borrower is required to be obtained by the Borrower in connection
   with the execution and delivery of the Loan Documents, the
   borrowings under the Agreement or the payment by the Borrower of
   the Obligations.

        Please be advised that I am licensed  and qualified to
   practice law only in the State of New York and am familiar
   only with the laws of that State, and the General
   Corporation Law of the State of Delaware.  Accordingly, I am
   not called upon to express and do not express herein any
   opinion with regard to the effect, application,
   interpretation or construction of any law, rule or
   regulation other than the laws, rules and regulations of the
   State of New York and the General Corporation Law of the
   State of Delaware.

        This letter is solely for the use of the Lenders,
   Purchasers, and Participants in connection with their
   execution and delivery of the Agreement and is not to be
   used, circulated, quoted or otherwise referred to for any
   other purpose, nor is this letter to be filed with or
   referred to as a whole or in part in any document, and no
   person other than the Lenders, Purchasers and Participants
   is authorized to review or receive this letter or a copy of
   this letter or any excerpt or portion hereof, or to rely on
   this letter, for any purpose.


                                 Yours very truly,

        This Assignment Agreement (this "Assignment Agreement")

   Credit Agreement.

        2. ASSIGNMENT AND ASSUMPTION.  The Assignor hereby sells and

   Assignee shall have the rights and obligations of a Lender under
   the Loan Documents with respect to the rights and obligations
   assigned to the Assignee hereunder and (ii) the Assignor shall
   relinquish its rights and be released from its corresponding
   obligations under the Loan Documents with respect to the rights
   and obligations assigned to the Assignee hereunder.

        4. PAYMENTS OBLIGATIONS.  On and after the Effective Date, the
   Assignee shall be entitled to receive from the Agent all payments
   of principal, interest and fees with respect to the interest
   assigned hereby.  The Assignee shall advance funds directly to

   made on or after the Effective Date with respect to the interest

   of Loans hereunder, (i) the Assignee shall pay the Assignor, on
   the Effective Date, an amount equal to the principal amount of
   the portion of all Floating Rate Loans assigned to the Assignee
   hereunder and (ii) with respect to each Fixed Rate Loan made by
   the Assignor and assigned to the Assignee hereunder which is
   outstanding on the Effective Date, (a) on the last day of the
   Interest Period therefor or (b) on such earlier date agreed to by
   the Assignor and the Assignee or (c) on the date on which any
   such Fixed Rate Loan either becomes due (by acceleration or
   otherwise) or is prepaid (the date as described in the foregoing
   clauses (a), (b) or (c) being hereinafter referred to as the
   "Payment Date"), the Assignee shall pay the Assignor an amount
   equal to the principal amount of the portion of such Fixed Rate
   Loan assigned to the Assignee which is outstanding on the Payment
   Date.  If the Assignor and the Assignee agree that the Payment
   Date for such Fixed Rate Loan shall be the Effective Date, they
   shall agree to the interest rate applicable to the portion of
   such Loan assigned hereunder for the period from the Effective
   Date to the end of the existing Interest Period applicable to
   such Fixed Rate Loan (the "Agreed Interest Rate") and any
   interest received by the Assignee in excess of the Agreed
   Interest Rate shall be remitted to the Assignor.  In the event
   interest for the period from the Effective Date to but not
   including the Payment Date is not paid by the Borrower with
   respect to any Fixed Rate Loan sold by the Assignor to the
   Assignee hereunder, the Assignee shall pay to the Assignor
   interest for such period on the portion of such Fixed Rate Loan
   sold by the Assignor to the Assignee hereunder at the applicable
   rate provided by the Credit Agreement.  In the event a prepayment
   of any Fixed Rate Loan which is existing on the Payment Date and
   assigned by the Assignor to the Assignee hereunder occurs after
   the Payment Date but before the end of the Interest Period
   applicable to such Fixed Rate Loan, the Assignee shall remit to
   the Assignor the excess of the prepayment penalty paid with
   respect to the portion of such Fixed Rate Loan assigned to the
   Assignee hereunder over the amount which would have been paid if
   such prepayment penalty was calculated based on the Agreed
   Interest Rate.  The Assignee will also promptly remit to the
   Assignor (i) any principal payments received from the Agent with
   respect to Fixed Rate Loans prior to the Payment Date and (ii)
   any amounts of interest on Loans and fees received from the Agent
   which relate to the portion of the Loans assigned to the Assignee
   hereunder for periods prior to the Effective Date, in the case of
   Floating Rate Loans, or the Payment Date, in the case of Fixed
   Rate Loans, and not previously paid by the Assignee to the
   Assignor.]*  In the event that either party hereto receives any
   payment to which the other party hereto is entitled under this
   Assignment Agreement, then the party receiving such amount shall
   promptly remit it to the other party hereto.

          1Each Assignor may insert its standard payment provisions in
        lieu of the payment terms included in this Exhibit.

        5. FEES PAYABLE BY THE ASSIGNEE.  The Assignee shall pay to the
   Assignor a fee on each day on which a payment of interest or
   [commitment] fees is made under the Credit Agreement with respect
   to the amounts assigned to the Assignee hereunder (other than a
   payment of interest or commitment fees for the period prior to
   the Effective Date or, in the case of Fixed Rate Loans, the
   Payment Date, which the Assignee is obligated to deliver to the
   Assignor pursuant to Section 4 hereof).  The amount of such fee
   shall be the difference between (i) the interest or fee, as
   applicable, paid with respect to the amounts assigned to the
   _____________________________
   1  to be inserted if required by the Credit Agreement.

                                      50

   <PAGE>

   Assignee hereunder and (ii) the interest or fee, as applicable,
   which would have been paid with respect to the amounts assigned
   to the Assignee hereunder if each interest rate was     of 1%
   less than the interest rate paid by the Borrower or if the
   commitment fee was     of 1% less than the commitment fee
   paid by the Borrower, as applicable.  In addition, the Assignee
   agrees to pay     % of the recordation fee required to be paid
   to the Agent in connection with this Assignment Agreement.

        6. REPRESENTATIONS OF THE ASSIGNOR; LIMITATIONS ON THE ASSIGNOR'S
   LIABILITY.  The Assignor represents and warrants that it is the
   legal and beneficial owner of the interest being assigned by it
   hereunder and that such interest is free and clear of any adverse
   claim created by the Assignor.  It is understood and agreed that
   the assignment and assumption hereunder are made without recourse
   to the Assignor and that the Assignor makes no other
   representation or warranty of any kind to the Assignee.  Neither

   Loan Documents.

        7. REPRESENTATIONS OF THE ASSIGNEE.  The Assignee (i) confirms
   that it has received a copy of the Credit Agreement, together

   Loan Documents, (iii) appoints and authorizes the Agent to take

   Assignor harmless against any and all losses, costs and expenses
   (including, without limitation, reasonable attorneys' fees) and
   liabilities incurred by the Assignor in connection with or
   arising in any manner from the Assignee's non-performance of the
   obligations assumed under this Assignment Agreement.

        9. SUBSEQUENT ASSIGNMENTS.  After the Effective Date, the
   Assignee shall have the right pursuant to Section [12.3.1] of the
   Credit Agreement to assign the rights which are assigned to the
   Assignee hereunder to any entity or person, provided that (i) any
   such subsequent assignment does not violate any of the terms and
   conditions of the Loan Documents or any law, rule, regulation,
   order, writ, judgment, injunction or decree and that any consent
   required under the terms of the Loan Documents has been obtained
   and (ii) unless the prior written consent of the Assignor is

     ____________________________________________________________


                           [BANK LETTERHEAD]



   Attn:


   Dear          :


        __________________ (the "Bank") is interested in
   receiving information with respect to the Company which is
   non-public, confidential or proprietary in nature
   ("Information") in order to evaluate ____________ (the
   "Financing").  Accordingly, the Company and the Bank agree
   as follows:

        1. Non-Disclosure.  The Bank agrees that it will not
   disclose without the prior consent of the Company any
   Information which is furnished by Company to the Bank and
   which is designated by the Company to the Bank in writing as
   confidential, provided, however, that the Bank may disclose
   any Information:

             (a)  to its directors, employees, auditors or
                  counsel or any other party necessary in the
                  credit approval process (collectively
                  "representatives") to whom it is necessary to
                  show the Information, [each of which shall be
                  informed by the Bank of the confidential
                  nature of the Information]; and

             (b)  in any statement or testimony pursuant to a
                  subpoena or order by any court, governmental
                  body or other agency asserting jurisdiction
                  over the Bank, or as may otherwise be
                  required by law (provided that the Bank shall
                  give the Company prior notice of the
                  disclosure permitted by this Section (b)
                  unless such notice is prohibited by the
                  subpoena, order or law);

             (c)  upon the request or demand of any regulatory
                  agency or prospective authority having
                  jurisdiction over the Bank; and

             (d)  to prospective lenders in the primary and
                  secondary syndication, provided that all such
                  prospective lenders execute an agreement with
                  the Bank containing provisions substantially
                  the same as those contained in this
                  Agreement.

                                      61

   <PAGE>

        2. Public Information.  The restrictions contained in
   the Agreement shall not apply to Information which (a) is or
   becomes generally available to the public other than as a
   result of a disclosure by the Bank or the Bank's
   representatives; or (b) becomes available to the Bank on a
   non-confidential basis from a source other than the Company
   or one of its agents or (c) was known to the Bank on a non-
   confidential basis prior to its disclosure to the Bank by
   the Company or one of its agents.

        3. General Provisions.  This Agreement constitutes the
   entire agreement of the parties hereto and supersedes all
   prior agreements of the parties relating to the subject
   matter hereof.  The parties acknowledge however that, upon
   the execution of definitive loan documents, some or all of
   the confidentiality obligations of the Bank with respect to
   the Information hereunder may be superseded by the
   confidentiality provisions of the loan documents upon the
   terms set forth therein.  This agreement is only for the
   benefit of the parties hereto.  This Agreement shall be
   governed by, and construed in accordance with, the laws of
