                        "Adjusted CD Rate" shall mean, with respect to any 
                         ----------------

              amount to such Eurodollar Loan made by the Banks, and for a 
              maturity comparable to such Interest Period are offered to 
              the principal London office of Chemical Bank, or if Chemical

              principal office of any Affiliate of Chemical Bank, in 
              immediately available funds in the London interbank market at

                         -------------------

              to the greatest of (a) the Federal Funds Effective Rate in 
              effect on such day plus 1/2 of 1%, (b) the Prime Rate in 
              effect on such day and (c) the Base CD Rate in effect on such 
              day plus 1%.  For purposes hereof, "Prime Rate" shall mean

              the rate of interest per annum publicly announced from time 
              to time by Chemical Bank at its principal office in New York 
              City as its prime rate in effect on such day; each change in 
              the Prime Rate shall be effective on the date such change is 
              publicly announced as being effective.  "Base CD Rate" shall
                                                       ------------
              mean the sum of (a) the product of (i) the Three-Month 
              Secondary CD Rate and (ii) Statutory Reserves and (b) the 
              Assessment Rate.  If for any reason any Bank shall have 
              determined (which determination shall be conclusive absent 
              manifest error) that it is unable to ascertain the Federal 






              Funds Effective Rate or the Base CD Rate or both for any 
              reason, including the inability or failure of Chemical Bank 
              to obtain sufficient quotations in accordance with the terms 
              thereof, the Alternate Base Rate shall be determined without 
              regard to clause (a) or (c), or both, of the first sentence 
              of this definition, as appropriate, until the circumstances 
              giving rise to such inability no longer exist.  For purposes 
              of this Agreement, any change in the Alternate Base Rate due 
              to a change in the Prime Rate, the Federal Funds Effective 
              Rate or the Three Month Secondary CD Rate shall be effective 
              on the date such change in the Prime Rate, the Federal Funds 
              Effective Rate or the Three-Month Secondary CD Rate, 
              respectively, is announced.
              
                        "Arrangement Fee" shall have the meaning assigned
                         ---------------

                         ---------------
              annual rate (rounded upwards, if necessary, to the next 1/100 
              of 1%) most recently estimated by Chemical Bank as the then 
              current net annual assessment rate that will be employed in 
              determining amounts payable by Chemical Bank to the Federal 
              Deposit Insurance Corporation (or any successor) for 
              insurance by such Corporation (or such successor) of time 
              deposits made in dollars at Chemical Bank's domestic offices.
              
                        "Asset Coverage" shall mean the ratio which (x) the
                         --------------
              value of the total assets of the Company, less all 
              liabilities of the Company, including as a liability 
              provision for estimated Federal taxes on unrealized 
              appreciation of securities for which market quotations are 
              readily available, but excluding from liabilities (i) all 
              deferred income taxes relating to undistributed earnings of

              (a)  Each Bank, severally and not jointly, agrees, upon the 
              terms and subject to the conditions hereof, to make revolving 
              credit Loans (herein called "RC Loans") to the Company at any 
              time and from time to time from the date hereof until the 
              Maturity Date, or until the earlier termination of the 
              Commitments, in an aggregate principal amount at any one time 
              outstanding not to exceed the amount of its Commitment.  All 
              RC Loans shall be made from each Bank pro rata in accordance 
              with its Commitment.  Each Eurodollar Loan or CD Rate Loan 
              requested hereunder on any date shall be in the principal 
              amount of at least $500,000.  Any ABR Loan requested 
              hereunder on any date shall be in a principal amount of 
              $100,000 or an integral multiple thereof.  To the extent that 
              Loans (as defined in the Prior Agreement) are outstanding 
              under the Prior Agreement as of the date hereof, such Loans 
              shall continue to be outstanding as Loans of the same Type 
              and Interest Period hereunder (but shall bear interest at the

                        (b)  Each RC Loan shall be either an ABR Loan, a 
              Eurodollar Loan or a CD Rate Loan as the Company may request 
              pursuant to Section 2.02.  Each Bank may at its option 
              fulfill its Commitment with respect to any Eurodollar Loan by 
              causing a foreign branch or affiliate of such Bank to make 
              such Loan; provided that any such exercise of such option
                         --------
              shall not affect the obligation of the Company to repay such 
              Loan in accordance with the terms of this Agreement.  Loans 
              of more than one type may be outstanding at the same time.  






              Loans requested from, and maintained with, each Bank 
              hereunder need not be of the same type as those requested 
              from, and maintained with, the other Banks.
              
                        (c)  Each Bank shall make its Loans by depositing 
              immediately available funds in the regular deposit account of 
              the Company maintained with such Bank not later than 
              2:00 p.m., New York City time, on the date of such Loan.

              shall give each of the Banks irrevocable written, telegraphic 
              or telex notice (i) not later than 12:00 (noon), New York 
              City time, one Business Day before such Loan if such Loan is 
              to be an ABR Loan; (ii) not later than 10:00 a.m., New York 
              City time, two Business Days before such Loan if such Loan is 
              to be a CD Rate Loan and (iii) not later than 10:00 a.m., 
              New York City time, three Business Days before such Loan if 
              such Loan is to be a Eurodollar Loan.  Such notice shall 
              specify (i) whether the Loan then being requested of such 
              Bank is to be an ABR Loan, a CD Rate Loan or a Eurodollar 
              Loan, (ii) the date of such borrowing and amount thereof and 
              (iii) if such Loan is to be a Eurodollar Loan or CD Rate 
              Loan, the Interest Period with respect thereto.  If no 
              election as to the type of Loan is specified in such notice, 
              such Loan shall be an ABR Loan.  If no Interest Period with 
              respect to any Eurodollar Loan or CD Rate Loan is specified 
              in any such notice, then the Company shall be deemed to have 
              selected an Interest Period of one month's duration, in the 
              case of a Eurodollar Loan, or 30 days' duration, in the case 
              of a CD Rate Loan.  Such notice to any Bank for a Eurodollar 
              Loan or CD Rate Loan may condition such request upon a 
              maximum Adjusted LIBO Rate or Adjusted CD Rate; provided 
              that, if such Bank determines
                                   --------
              that the Adjusted LIBO Rate or Adjusted CD Rate, as the case 
              may be, will exceed the maximum specified by the Company, 
              such request shall be deemed a request for an ABR Loan.
              
                        (b)  The Company may continue any Eurodollar Loan 
              or CD Rate Loan or convert all or any part of any ABR Loan, 
              CD Rate Loan or Eurodollar Loan into a Loan of a different 
              type, in each case in accordance with Section 2.09 and 
              subject to the limitations set forth therein.
              
                        (c)  The Company shall not request from any Bank 
              more than a total of five new Eurodollar Loans and/or CD Rate 
              Loans or conversions to Eurodollar Loans from ABR Loans or CD 
              Rate Loans and/or to CD Rate Loans from ABR Loans or 
              Eurodollar Loans in any one calendar month.

              Company may borrow, pay, prepay and reborrow hereunder,

              including but not limited to the provisions for prepayment 
              set forth in Section 2.08.  The unpaid principal of and 
              accrued interest on the RC Loans shall be payable on the 
              Maturity Date.
              
                        SECTION 2.04.  Interest.  (a)  In the case of an
                                       --------
              ABR Loan, interest shall be payable at a rate per annum 
              (computed on the basis of the actual number of days elapsed 
              over a year of 360 days during any period that the Alternate 
              Base Rate is determined based upon the Base CD Rate or the 
              Federal Funds Effective Rate and, at all other times, 365 or 
              366 days, as the case may be) equal to the Alternate Base

                        (b)  In the case of a Eurodollar Loan, interest 
              shall be payable at a rate per annum (computed on the basis 
              of the actual number of days elapsed over a year of 360 days) 
              equal to the Adjusted LIBO Rate, plus one-half percent (1/
              2%).  Interest shall be payable on each Eurodollar Loan on 
              the applicable Interest Payment Dates, and at repayment or 
              the date of conversion of such Eurodollar Loan to a CD Rate 
              Loan or an ABR Loan.  Each Bank requested to make a 
              Eurodollar Loan hereunder shall determine the applicable 
              Adjusted LIBO Rate for each Interest Period as soon as 
              practicable after 10:00 a.m., New York City time, two

                        (c)  In the case of a CD Rate Loan, interest will 
              be payable at a rate per annum (computed on the basis of the 
              actual number of days elapsed over a period of 360 days) 
              equal to the Adjusted CD Rate, plus five-eighths percent 
              (5/8%).  Interest shall be payable on each CD Rate Loan on 
              the applicable Interest Payment Dates, and at repayment or 
              the date of conversion of such CD Rate Loan to an ABR Loan or 
              a Eurodollar Loan.  Each Bank requested to make a CD Rate 
              Loan hereunder shall determine the applicable Adjusted CD 
              Rate for each Interest Period as soon as practicable after 
              9:00 a.m., New York City time, on the date of the 
              commencement of such Interest Period and shall notify the 
              Company of the Adjusted CD Rate so determined.  Such 
              determination shall be conclusive absent manifest error.

              Date, computed at the rate of 1/4 of 1% per annum on the 
              average daily unused amount of such Bank's Commitment during 
              the period for which payment is made, payable quarterly on 
              the last day of each March, June, September and December and 
              on the Maturity Date or such earlier date as the Commitments 
              shall terminate or be reduced as provided herein, commencing 
              on the first of such dates to occur after the date hereof.
              
                        (b)  The Company agrees to pay each Bank, for its 
              own account, the fees separately agreed to by the Company and 
              the Banks (the "Arrangement Fees").

                        (c) The Company agrees to pay each Bank, on the 
              last Business Day of March, June, September and December in 
              each year, and on the date on which all Loans shall be paid 
              in full and all Commitments shall be terminated as provided 
              herein, a utilization fee ("Utilization Fee") equal

              to .125% per annum on the average aggregate outstanding 
              amount of Loans during the quarter or other period then 
              ended, if during such quarter or other period the average 
              daily amount of all Loans outstanding exceeds 50% of the 
              average daily aggregate commitments in effect.
              
                        (d) All Fees shall be paid on the date due, in 
              immediately available funds, to each of the Banks.  Once 
              paid, none of the Fees shall be refundable under any 
              circumstances.
              
                        SECTION 2.06.  Termination and Reduction of
                                       ----------------------------
              Commitments.  Upon at least two Business Days prior written,
              -----------
              telegraphic or telex notice to the Banks, the Company may at 
              any time in whole permanently terminate, or from time to time 
              permanently reduce, the Commitments.  Each partial reduction 
              of the Commitments shall be in the aggregate principal amount 
              of $100,000 or an integral multiple thereof.  In the event of 
              a partial reduction of the Commitments, such reduction shall 
              be made pro rata among the Banks in accordance with their 
              respective Commitments. In no event shall the Commitment of 
              any Bank be reduced to an amount less than the then 
              outstanding unpaid principal balance of the Note given in 
              favor of such Bank.
              
                        SECTION 2.07.  Alternative Rate of Interest. 
                                       ----------------------------
              (a)  In the event, and on each occasion, that on the day two 






              Business Days prior to the commencement of any Interest 
              Period for a Eurodollar Loan, any Bank shall have determined 
              (which determination shall be conclusive and binding upon the 
              Company) that dollar deposits in the amount of the unpaid 
              principal amount of such Eurodollar Loan are not generally 
              available in the London interbank market, or that the rate at 
              which such dollar deposits are being offered will not 
              adequately and fairly reflect the cost to such Bank of making 
              or maintaining the principal amount of such Eurodollar Loan 
              during such Interest Period, such Bank shall promptly give 
              written, telegraphic or telex notice of such determination to 
              the Company and the other Banks.  In such event the Company 
              and the Bank giving such notice may agree on a substitute 
              rate of interest.  For one Business Day after receipt of such 
              notice, the Company shall have the right to withdraw its 
              request for a Eurodollar Loan pursuant to Section 2.02 by 
              written, telegraphic or telex notice to the Banks.  If the 
              Company and the Bank giving notice as hereinabove provided 
              have not agreed on a substitute rate of interest, any request 
              by the Company to make, convert to or maintain a Eurodollar 
              Loan pursuant to Sections 2.02 (unless withdrawn as provided 
              above) or 2.09 shall be deemed a request for an ABR Loan in 
              respect of any Bank giving such notice.  After such notice 
              shall have been given and until the circumstances giving rise 
              to such notice no longer exist or until the Company and such 
              Bank agree on a substitute rate of interest, each request for 
              a Eurodollar Loan shall be deemed to be a request for an ABR 
              Loan in respect of any such Bank giving such notice.  Each 
              determination by a Bank hereunder shall be conclusive absent 
              manifest error.  Any Bank giving notice as described above 
              shall notify the Company at such time as the circumstances 
              giving rise to such notice no longer exist.
              
                        (b)  In the event, and on each occasion, that on 
              the day of the commencement of any Interest Period for a CD 
              Rate Loan, any Bank shall have determined (which determina-
              tion shall be conclusive and binding upon the Company) that 
              such Bank is unable to obtain bids for its dollar deposits 
              for such Interest Period in the manner contemplated by the 
              term "Fixed CD Rate", or that the rate at which such dollar 
              deposits are being offered will not adequately and fairly 
              reflect the cost to such Bank of making or maintaining the 
              principal amount of such CD Rate Loan during such Interest 
              Period, such Bank shall promptly give written, telegraphic or 
              telex notice of such determination to the Company and the 
              other Banks.  In such event the Company and the Bank giving 
              such notice may agree on a substitute rate of interest.  For 
              one Business Day after receipt of such notice, the Company 
              shall have the right to withdraw its request for a CD Rate 
              Loan pursuant to Section 2.02 by written, telegraphic or 
              telex notice to the Banks.  If the Company and the Bank 






              giving notice as hereinabove provided have not agreed on a 
              substitute rate of interest, any request by the Company to 
              make, convert to or maintain a CD Rate Loan pursuant to 
              Sections 2.02 (unless withdrawn as provided above) or 2.09 
              shall be deemed a request for an ABR Loan in respect of any 
              Bank giving such notice.  After such notice shall have been 
              given and until the circumstances giving rise to such notice 
              no longer exist or until the Company and such Bank agree on a 
              substitute rate of interest, each request for a CD Rate Loan 
              shall be deemed to be a request for an ABR Loan in respect of 
              any such Bank giving such notice.  Each determination by a 
              Bank hereunder shall be conclusive absent manifest error.  
              Any Bank giving notice as described above shall notify the 
              Company at such time as the circumstances giving rise to such 
              notice no longer exist.
              
                        SECTION 2.08.  Prepayment of Loans.  (a)  The
                                       -------------------
              Company shall have the right at any time and from time to 
              time to prepay any Loan, in whole or in part, without premium 
              or penalty, upon at least two Business Days' prior written, 
              telegraphic or telex notice to the Banks; provided, however,
                                                        --------  -------
              that (i) each such partial prepayment shall be in the 
              aggregate principal amount of $100,000 or an integral 
              multiple thereof, (ii) such prepayments shall be made pro 
              rata among the Banks in accordance with their respective 
              Commitments, and (iii) each prepayment shall be accompanied 
              by accrued interest on the principal amount being prepaid to 
              the date of prepayment.
              
                        (b)  Each notice of prepayment shall specify the 
              prepayment date and the principal amount of each Loan to be 
              prepaid, shall be irrevocable and shall commit the Company to 
              prepay such Loan by the amount stated therein.
              
                        (c)  If the outstanding unpaid principal balance of 
              the Note given in favor of any Bank on the date of any such 
              payment includes one or more of ABR Loans, CD Rate Loans and 
              Eurodollar Loans, the notice given to such Bank shall specify 
              the extent to which such payment is to be applied against 
              such ABR Loans, CD Rate Loans and Eurodollar Loans.  If the 
              outstanding unpaid principal balance of the Note given in 
              favor of any Bank on the date of any such payment includes 
              more than one Eurodollar Loan or CD Rate Loan, the notice 
              given to such Bank shall specify the Eurodollar Loans or CD 
              Rate Loans, as the case may be, against which such payment is 
              to be applied, and the extent to which it is to be applied 
              against each Eurodollar Loan or CD Rate Loan, as the case may 
              be, so specified.  To the extent not otherwise so specified, 
              each such payment shall be applied, first, against any 
              outstanding ABR Loans, and next, after all such ABR Loans 
              have been repaid, to the outstanding Eurodollar Loans and CD 






              Rate Loans in the order of expiration of their respective 
              Interest Periods.
              
                        (d)  The Company shall reimburse any Bank on demand 
              for any loss incurred or to be incurred by it in the 
              reemployment of the funds released by (i) any prepayment or 
              payment of any Eurodollar Loan or CD Rate Loan pursuant to 
              Section 2.10(a) or 2.05 hereof, as the case may be, in whole 
              or in part on a date prior to the last day of an Interest 
              Period for such Eurodollar Loan or CD Rate Loan, (ii) any 
              prepayment or payment of any Eurodollar Loan or CD Rate Loan 
              by reason of acceleration of the indebtedness due hereunder 
              on the occurrence of an Event of Default pursuant to 
              Article VII hereof or (iii) by any failure or refusal of the 
              Company to accept (or to meet the conditions precedent for) 
              any Eurodollar Loan or CD Rate Loan as to which notice was 
              given by the Company hereunder.  Such loss shall be the 
              difference as reasonably determined by such Bank between its 
              cost of obtaining the funds for the Loan being prepaid or 
              refused and any lesser amount realized by such Bank in 
              reemploying such funds during the period from the date of 
              prepayment or refusal to the end of the Interest Period of 
              the Eurodollar Loan or CD Rate Loan being repaid or the 
              Interest Period specified in the notice given by the Company, 
              as the case may be; provided that such loss shall not include 
              any loss, damage or expense resulting from the failure of any 
              Person to whom any such funds are loaned to timely and duly 
              repay the same, or from any other default or nonperformance 
              of such Person's obligations.
              
                        SECTION 2.09.  Continuation and Conversion of
                                       ------------------------------
              Loans.  The Company shall have the right, at any time, with
              -----
              at least three Business Days' prior irrevocable written, 
              telegraphic or telex notice to the Banks, (i) to continue any 
              Eurodollar Loan or CD Rate Loan or portion thereof into a 
              subsequent Interest Period, or (ii) to convert any type of 
              Loan or portion thereof into a Loan of a different type, 
              subject to the following:
              
                        (a) no Event of Default or event which with notice 
                   or lapse of time or both would constitute an Event of 
                   Default shall have occurred and be continuing at the 
                   time of such continuation or conversion and, with 
                   respect to Eurodollar Loans or CD Rate Loans, no notice 
                   described in Section 2.07 or 2.11 (which shall not have 
                   been rescinded) shall have been given by the Bank from 
                   which the Eurodollar Loan or CD Rate Loan is requested;
              
                        (b) each conversion shall be effected by the Banks 
                   applying the proceeds of the new Loan to the Loan (or 
                   portion thereof) being converted;
              






                        (c) if the new Loan made in respect of the conver-
                   sion shall be a Eurodollar Loan or CD Rate Loan, the 
                   first Interest Period with respect thereto shall 
                   commence on the date of conversion;
              
                        (d) Eurodollar Loans and CD Rate Loans may be 
                   converted on their respective Interest Payment Dates 
                   only, except conversion of Eurodollar Loans or CD Rate 
                   Loans to ABR Loans to the extent required to be 
                   converted pursuant to Section 2.11(a);
              
                        (e) each request for a Eurodollar Loan or CD Rate 
                   Loan or for a continuation thereof which shall fail to 
                   state the applicable Interest Period, shall be for one 
                   month's duration or 30 days' duration, respectively;
              
                        (f) no more than a total of five new Eurodollar 
                   Loans and/or CD Rate Loans or conversions to Eurodollar 
                   Loans from ABR Loans or CD Rate Loans and/or to CD Rate 
                   Loans from ABR Loans or Eurodollar Loans may be 
                   requested from any Bank in any one calendar month; 
              
                        (g) any portion of a Loan maturing or required to 
                   be repaid in less than one month may not be converted 
                   into or continued as a Eurodollar Loan; 
              
                        (h) any portion of a Loan maturing or required to 
                   be repaid in less than 30 days may not be converted into 
                   or continued as a CD Rate Loan;
              
                        (i) any portion of a Eurodollar Loan or CD Rate 
                   Loan which cannot be converted into or continued as a 
                   Eurodollar Rate Loan or a CD Rate Loan by reason of 
                   clauses (g) and (h) above shall be automatically 
                   converted at the end of the Interest Period in effect 
                   for such Loan into an ABR Loan; and 
              
                        (j) each request for conversion of an ABR Loan to a 
                   Eurodollar Loan or CD Rate Loan hereunder shall be in 
                   the principal amount of at least $500,000.
              
              In the event that the Company shall not give notice to 
              continue any Eurodollar Loan or CD Rate Loan, such Loan 
              (unless repaid) shall automatically become an ABR Loan at the 
              expiration of the then current Interest Period. The Company 
              may condition any request to any Bank for conversion to or 
              maintenance of a Eurodollar Loan or CD Rate Loan upon a 
              maximum Adjusted LIBO Rate or maximum Adjusted CD Rate, as 
              the case may be; provided that, if such Bank determines that 
              the Adjusted LIBO Rate or Adjusted CD Rate, as the case may 
              be, will exceed such maximum specified by the Company, such 
              request shall be deemed a request for an ABR Loan.
              






                        SECTION 2.10.  Increased Costs.
                                       ---------------
              (a) Notwithstanding any other provision herein, if after the 
              date of this Agreement any change in applicable law or 
              regulation or in the interpretation or administration thereof 
              by any Governmental Authority charged with the interpretation 
              or administration thereof (whether or not having the force of 
              law) shall change the basis of taxation of payments to any 
              Bank of the principal of or interest on any Eurodollar Loan 
              or CD Rate Loan or any other fees or amounts payable 
              hereunder (other than taxes imposed on the overall net income 
              of such Bank by the jurisdiction in which such Bank has its 
              principal office or by any political subdivision or taxing 
              authority therein), or shall impose, modify or deem 
              applicable any reserve, special deposit or similar require-
              ment against assets of, deposits with or for the account of, 
              or credit extended by, such Bank or shall impose on such Bank 
              or the London interbank market any other condition affecting 
              this Agreement or the Eurodollar Loans or CD Rate Loans, and 
              the result of any of the foregoing shall be to increase the 
              cost to such Bank of making or maintaining any Eurodollar 
              Loan or CD Rate Loan or to reduce the amount of any sum 
              received or receivable by such Bank hereunder (whether of 
              principal, interest or otherwise) in respect thereof, by an 
              amount deemed by such Bank to be material, then (to the 
              extent the amount is not included in the computation of the 
              Adjusted LIBO Rate or Adjusted CD Rate (as the case may be)), 
              the Company shall pay to such Bank, upon such Bank's demand, 
              such additional amount or amounts as will compensate such 
              Bank for such additional costs or reduction.
              
                        (b)  If any Bank shall have determined that the 
              applicability of any law, rule, regulation, agreement or 
              guideline adopted pursuant to or arising out of the July 1988 
              report of the Basle Committee on Banking Regulations and 
              Supervisory Practices entitled "International Convergence of 
              Capital Measurement and Capital Standards", or the adoption 
              after the date hereof of any other law, rule, regulation, 
              agreement or guideline regarding capital adequacy, or any 
              change in any of the foregoing or in the interpretation or 
              administration of any of the foregoing by any Governmental 
              Authority, central bank or comparable agency charged with the 
              interpretation or administration thereof, or compliance by 
              any Bank (or any lending office of such Bank) or any Bank's 
              holding company with any request or directive regarding 
              capital adequacy (whether or not having the force of law) of 
              any such Governmental Authority, central bank or comparable 
              agency, has or would have the effect of reducing the rate of 
              return on such Bank's capital or on the capital of such 
              Bank's holding company, if any, as a consequence of this 
              Agreement or the Loans made by such Bank pursuant hereto to a 
              level below that which such Bank or such Bank's holding 
              company could have achieved but for such adoption, change or 
              compliance (taking into consideration such Bank's policies 






              and the policies of such Bank's holding company with respect 
              to capital adequacy) by an amount deemed by such Bank to be 
              material, then from time to time, after submission by such 
              Bank to the Company of a written request therefor, the 
              Company shall pay to such Bank such additional amount or 
              amounts as will compensate such Bank or such Bank's holding 
              company for any such reduction suffered.
              
                        (c)  A certificate of each Bank setting forth such 
              amount or amounts and the basis for determination from time 
              to time of such amount or amounts as shall be necessary to 
              compensate such Bank or its holding company as specified in 
              paragraph (a) or (b) above, as the case may be, shall be 
              delivered to the Company and shall be conclusive absent 
              manifest error.  The Company shall pay each Bank the amount 
              shown as due on any such certificate delivered by it within 
              10 days after its receipt of the same. 
              
                        (d)  Failure on the part of any Bank to demand 
              compensation for any increased costs or reduction in amounts 
              received or receivable or reduction in return on capital with 
              respect to any period shall not constitute a waiver of such 
              Bank's right to demand compensation with respect to such 
              period within a commercially reasonable time or any other 
              period.  The protection of this Section shall be available to 
              each Bank regardless of any possible contention of the 
              invalidity or inapplicability of the law, rule, regulation, 
              guideline or other change or condition which shall have 
              occurred or been imposed.
              
                        SECTION 2.11.  Change in Legality. 
                                       ------------------
              (a)  Notwithstanding anything to the contrary herein 
              contained, if any change in any law or regulation or in the 
              interpretation thereof by any Governmental Authority charged 
              with the administration or interpretation thereof shall make 
              it unlawful for any Bank to make or maintain any Eurodollar 
              Loan or to give effect to its obligations as contemplated 
              hereby then, by written notice to the Company and to the 
              other Banks, (i) such Bank may require payment (together with 
              accrued interest to the date of payment) of all outstanding 
              Eurodollar Loans due to it hereunder, whereupon all such 
              Eurodollar Loans then outstanding shall be automatically 
              converted to an ABR Loan (notwithstanding Section 2.08, but 
              otherwise subject to Section 2.08(d)), as of the effective 
              date of such notice as provided in paragraph (b) below, 
              (ii) the obligation of such Bank to continue or convert to 
              Eurodollar Loans shall terminate immediately and (iii) each 
              subsequent request to such Bank for a Eurodollar Loan shall 
              be deemed to be a request for an ABR Loan.  Any Bank giving 
              such notice shall rescind such notice if the conditions 
              giving rise to it shall cease to exist.  If the Company shall 
              be prohibited from incurring, continuing or converting to a 
              Eurodollar Loan from any Bank, Eurodollar Loans shall be 






              made, continued or converted by the other Banks pro rata in 
              accordance with their respective Commitments then in effect.
              
                        (b)  For purposes of Section 2.11(a)(i), a notice 
              to the Company by any Bank shall be effective, if lawful, and 
              if any Eurodollar Loans shall then be outstanding, on the 
              last day of the then current Interest Period or, if there is 
              more than one current Interest Period, on the last day of 
              each such Interest Period, respectively; otherwise, such 
              notice shall be effective on the date of receipt by the 
              Company.
              
                        SECTION 2.12.  Indemnity.  The Company shall
                                       ---------
              indemnify each Bank against any loss or expense which such 
              Bank may sustain or incur as a consequence of any default in 
              prepayment of the principal amount of any Eurodollar Loan or 
              any CD Rate Loan or any part thereof or interest accrued 
              thereon, as and when due and payable by irrevocable notice, 
              including but not limited to any loss or reasonable expense 
              sustained or incurred in liquidating or employing deposits 
              from third parties acquired to effect or maintain such 
              Eurodollar Loan or CD Rate Loan or any part thereof.  Such 
              Bank shall provide to the Company a statement, supported 
              where applicable by documentary evidence, explaining the 
              amount of any such loss or expense, which statement shall be 
              conclusive absent manifest error.
              
                        SECTION 2.13.  Money of Account; Payments. 
                                       --------------------------
              (a)  This transaction is an international loan transaction in 
              which the specification of dollars is of the essence, and 
              dollars shall be the currency of account and of payment in 
              all events.  The payment obligations of the Company shall not 
              be discharged by an amount paid in another currency, whether 
              pursuant to a judgment or otherwise, to the extent that the 
              amount so paid on prompt conversion to dollars under normal 
              banking procedures shall not yield the amount of dollars due 
              hereunder.  In the event that any payment made in a currency 
              other than dollars, whether pursuant to a judgment or 
              otherwise, upon conversion shall not yield such amount of 
              dollars, each Bank shall be entitled to demand immediate 
              payment of, and shall have a separate cause of action for, 
              the dollar deficiency.  
              
                        (b)  All payments by the Company under this 
              Agreement and under any other Loan Document shall be made in 
              immediately available funds at the office of the Bank to 
              which such payment is due as set forth in the preamble hereof 
              by 12:00 noon, New York City time, on the date on which such 
              payment shall be due.
              






                        SECTION 2.14.  Loan Records.  The Loan Account
                                       ------------
              established and maintained by each Bank hereunder shall 
              constitute prima facie evidence of such Bank's Loans and any 
              extension or renewal thereof made pursuant to this Agreement.
              
                        SECTION 2.15.  The Notes.  Should the Company and a
                                       ---------
              Bank so elect, a Note may be utilized to evidence the Loans 
              outstanding from such Bank to the Company.  Simultaneously 
              with the execution of a Note by the Company, (i) the 
              principal balance of all outstanding Loans from the Bank in 
              whose favor the Note is given shall be recorded on the 
              schedule attached to the Note (together with other 
              information, if any, required by the schedule), and (ii) the 
              Loan Account with respect to the foregoing shall be reduced 
              to zero.  Thereafter, the Note shall be utilized to record 
              and evidence all Loans from, and all repayments to, the Bank 
              in whose favor the Note is given, and the Loan Account of 
              such Bank shall remain at zero.
              
                        SECTION 2.16.  Use of Proceeds.  The proceeds of
                                       ---------------
              the Loans shall be used for the working capital and other 
              general corporate purposes of the Company (including, without 
              limitation, acquisitions).

              --------------
              each Bank a consolidated balance sheet of the Company and its 
              consolidated Subsidiaries as at December 31, 1994, and the

              then ended, all certified by KPMG Peat Marwick, independent

              operations for such period, have been prepared in accordance 
              with GAAP consistently followed throughout the periods 
              involved (except as set forth in the notes to such financial 
              statements) and show all material liabilities, direct or

              financial or otherwise, of the Company and its Subsidiaries

              and its Subsidiaries have no obligations or liabilities, 
              contingent or otherwise, which are material to the Company 
              and its Subsidiaries considered as a whole, and which have 
              not been disclosed in the audited year-end financial 
              statements (and accompanying schedules and notes) referred to 
              in paragraph (a) above, other than as expressly disclosed in

                        SECTION 3.09.  Investment Company Act.  The Company
                                       ----------------------
              is not an "Investment Company" or a company "controlled" by 
              an "Investment Company", within the meaning of the Investment 
              Company Act of 1940, as amended.
              
                        SECTION 3.10.  Employee Benefit Plans.  No
                                       ----------------------
              Reportable Event has occurred during the immediately 
              preceding six-year period with respect to any Plan, and each 
              Plan has complied and has been administered in all material 
              respects with applicable provisions of ERISA and the Code.  
              Except as set forth in Schedule 3.10, the present value of 
              all benefit liabilities under each Single Employer Plan 
              maintained by the Company or any Commonly Controlled Entity 
              (based on those assumptions used to fund such Plan) did not, 
              as of the last annual valuation date applicable thereto, 
              exceed the value of the assets of such plan.  None of the 
              Company nor any Commonly Controlled Entity has (a) adopted 
              any amendment to a Plan that would require the provision of 
              security pursuant to Section 401(a)(29) of the Code or 
              Section 307 of ERISA, (b) filed pursuant to Section 412(d) of 
              the Code or Section 303(d) of ERISA an application for a 
              waiver of the minimum funding standard with respect to any 
              Plan, (c) incurred any liability under Title IV of ERISA, 
              (d) withdrawn or partially withdrawn from any Plan or 
              Multiemployer Plan, or (e) received from the PBGC or a plan 
              administrator any notice relating to the intention to 
              terminate any Plan or Plans or to appoint a trustee to 
              administer any Plan.  None of the Company nor any Commonly 
              Controlled Entity is aware of (x) the existence with respect 
              to any Plan of an "accumulated funding deficiency" (as 
              defined in Section 412 of the Code or Section 302 of ERISA), 
              whether or not waived, (y) the occurrence of a "prohibited 
              transaction" (as defined in Section 4975 of the Code or as 
              described in Section 406 of ERISA) with respect to which 
              there exists no statutory or administrative exemption and 
              with respect to which the Company or any Commonly Controlled 
              Entity, or any person indemnified by the Company or any 
              Commonly Controlled Entity, is directly or indirectly liable 
              or (z) any other event or condition with respect to a Plan or 
              Multiemployer Plan that could reasonably result in liability 
              of the Company or any Commonly Controlled Entity.  Except as 
              set forth in Schedule 3.10, on the date of this Agreement and 






              for the immediately preceding six-year period, neither the 
              Company nor any Commonly Controlled Entity participates in or 
              is subject to any Multiemployer Plan.  In the event that 
              during the term of this Agreement the Company or any Commonly 
              Controlled Entity participates in or becomes subject to any 
              Multiemployer Plans, the liability to which the Company or 
              any Commonly Controlled Entity would become subject under 
              ERISA if the Company or any Commonly Controlled Entity were 
              to withdraw completely from all Multiemployer Plans, if any, 
              as of the valuation date most closely preceding the date of 
              determination will not be material to the business, 
              operations, property or financial or other condition of the 
              Company.  In the event that during the term of this Agreement 
              the Company or any Commonly Controlled Entity participates in 
              or becomes subject to any Multiemployer Plans, such 
              Multiemployer Plans, if any, will neither be in 
              Reorganization nor Insolvent.

                                       -------------------
              proceeds of any Loan hereunder will be used for any purpose 
              which violates, or which would be inconsistent with, the 
              provisions of Regulation U of the Board as now and from time 
              to time hereafter in effect.  If requested by any Bank, the 
              Company will furnish to each Bank a statement to the 
              foregoing effect in conformity with the requirements of Form 
              F.R. U-1 referred to in said Regulation U.

                                       ---------------
              use the proceeds of the Loans only for the purposes specified 
              in Section 2.16.
              
                        SECTION 3.13.  Subsidiaries.  Schedule 3.13 sets

              forth as of the date of this Agreement a list of all 
              Subsidiaries of the Company and the percentage ownership 
              interest of the Company therein.

              equity or at law)) and (c) covering such additional matters 
              relating to the transaction contemplated hereby as the Banks 
              shall reasonably and timely request.

              unpaid principal balance of the Note given in favor of such

              become immediately due and payable without presentment, 
              demand, protest or notice of any kind, all of which are 
              hereby expressly waived, anything contained herein to the 
              contrary notwithstanding.  The failure of a Bank to give any 
              notice described above to the other Banks shall not affect 
              the validity of such notice to the Company.

              enforcement and protection of the rights of the Banks in 
              connection with this Agreement and the other Loan Documents 
              or in connection with the Loans made or the Notes issued

                        SECTION 8.03.  Indemnification.  The Company agrees
                                       ---------------
              to indemnify each Bank from and hold each of them harmless 
              against any and all liabilities, claims, damages or expenses 
              incurred by any of them (excluding any liabilities, claims, 
              damages or expenses of any Bank arising from gross 
              negligence, fraud or breach of fiduciary duty owed to third 
              parties on the part of such Bank or arising from any 
              assertion, putative or otherwise, as to the legal capacity or 
              authority of any Bank to execute and deliver this Agreement 
              or in respect of any law governing the corporate powers of 
              any Bank to perform its obligations hereunder) arising out of 
              or by reason of the consummation of the transactions 
              contemplated by this Agreement, or the use or contemplated 






              use of proceeds of the Loans, including, without limitation, 
              the fees and disbursements of counsel incurred in connection 
              with any investigation, litigation or other proceedings 
              (whether or not any Bank is a party thereto) arising out of 
              or by reason of any of the aforesaid; provided that the
                                                    --------
              foregoing shall not apply to any liability, claim, damage or 
              expense (i) incurred by any Bank against any other Bank here-
              under, (ii) arising from the breach by any Bank of any of its 
              obligations to the Company hereunder or (iii) arising out of 
              any commitment made by any Bank which would be breached by 
              performance of such Bank's obligations hereunder.  Each Bank 
              will promptly give the Company written notice of the 
              assertion of any claim which it believes is subject to the 
              indemnity set forth in this Section 8.03 and will, upon the 
              request of the Company, promptly furnish the Company with all 
              material in its possession relating to such claims or the 
              defense thereof to the extent that such Bank may do so 
              without breach of duty to others.
              
                        SECTION 8.04.  Set-off.  (a)  Each Bank agrees that
                                       -------
              if it shall, through the exercise of a right of banker's 
              lien, set-off or counterclaim against the Company, obtain 
              payment in respect of one or more Loans made by it as a 
              result of which the unpaid portion of the Loans made by it is 
              proportionately less than the unpaid portion of the Loans 
              made by any other Bank (i) it shall simultaneously purchase 
              from such other Bank a participation in the Loans made by 
              such other Bank, so that the aggregate unpaid principal 
              amount of all Loans and participations in Loans made by each 
              Bank shall be in the same proportion to the aggregate unpaid 
              principal amounts of all Loans then outstanding as the 
              principal amount of such Loans made by it prior to such 
              exercise of banker's lien, set-off or counterclaim and 
              (ii) such other adjustments shall be made from time to time 
              as shall be equitable to ensure that all the Banks share such 
              payment pro rata; provided, however, that if any such
                                --------  -------
              purchase or purchases shall be made pursuant to clause (i) 
              above and the payment giving rise thereto shall be recovered, 
              such purchase or purchases shall be rescinded to the extent 
              of such recovery and the purchase price or prices restored 
              without interest.
              
                        (b)  If an Event of Default shall have occurred and 
              be continuing, each Bank is hereby authorized at any time and 
              from time to time, to the fullest extent permitted by law, to 
              set-off and apply any and all deposits (general or special, 
              time or demand, provisional or final) at any time held and 
              other indebtedness at any time owing by such Bank to or for 
              the credit or the account of the Company against any of and 
              all the obligations of the Company now or hereafter existing 
              under this Agreement and other Loan Documents held by such 






              Bank, irrespective of whether or not such Bank shall have 
              made any demand under this Agreement or such other Loan 
              Document and although such obligations may be unmatured.  The 
              rights of each Bank under this Section 8.04(b) are in 
              addition to other rights and remedies (including other rights 
              of set-off) which such Bank may have.
              
                        SECTION 8.05.  APPLICABLE LAW.  THIS AGREEMENT AND
                                       --------------
              THE OTHER LOAN DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE 
              WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

              this Agreement and in the certificates or other instruments 
              prepared or delivered in connection with or pursuant to this 
              Agreement or any other Loan Document shall be considered to 
              have been relied upon by the Banks and shall survive the 
              making by the Banks of the Loans hereunder, and the execution 
              and delivery to the Banks of the Notes evidencing such Loans, 
              regardless of any investigation made by the Banks or on their 
              behalf, and shall continue in full force and effect so long 
              as any amounts payable hereunder or thereunder shall be 
              outstanding and unpaid.  Whenever in this Agreement any of 
              the parties hereto is referred to, such reference shall be 






              deemed to include the successors and assigns of such party, 
              and all covenants, promises and agreements by or on behalf of 
              the Company or the Banks which are contained in this 
              Agreement shall inure to the benefit of the successors and

              amount would become due and payable on other than a Business 
              Day, such payment shall instead become due on the next 
              succeeding Business Day, and, in the case of principal, 
              interest shall be payable thereon at the rate herein 
              specified during such extension; provided, however, that any
                                               --------  -------

              provisions contained herein shall not in any way be affected 
              or impaired thereby.  The parties shall endeavor in good-
              faith negotiations to replace the invalid, illegal or 
              unenforceable provisions with valid provisions the economic 
              effect of which comes as close as possible to that of the 
              invalid, illegal or unenforceable provisions.
              
                        SECTION 8.10.  Counterparts.  This Agreement may be

              effective when copies hereof which, when taken together, bear 
              the signatures of each of the parties hereto shall be 
              delivered to the Company and the Banks.
              
                        SECTION 8.11.  Successors and Assigns.

              referred to, such reference shall be deemed to include the 
              successors and assigns of such party; and all covenants, 
              promises and agreements by or on behalf of the Company or the

              all or a portion of its interests, rights and obligations

              Company must give its prior written consent to such 
              assignment (which consent shall not be unreasonably 
              withheld), (ii) the amount of the Commitment of the assigning 
              Bank subject to each such assignment (determined as of the

              assignment is delivered to such Bank) shall not be less than 
              $5,000,000 and the amount of the Commitment of such Bank 
              remaining after such assignment shall not be less than

              such assignment shall execute and deliver to the assigning 
              Bank an Assignment and Acceptance.  From and after the 
              effective date specified in each Assignment and Acceptance, 
              which effective date shall be at least five Business Days 
              after the execution thereof, (A) the assignee thereunder 
              shall be a party hereto and, to the extent of the interest 
              assigned by such Assignment and Acceptance, become and have 
              the rights and obligations of a Bank under this Agreement and 
              (B) the assigning Bank thereunder shall, to the extent of the 
              interest assigned by such Assignment and Acceptance, be 
              released from its obligations under this Agreement (and, in 
              the case of an Assignment and Acceptance covering all or the 
              remaining portion of an assigning Bank's rights and 
              obligations under this Agreement, such Bank shall cease to be 
              a party hereto but shall continue to be entitled to the 
              benefits of Sections 2.10, 2.12 and 8.02, as well as to any 
              Fees or other amounts accrued for its account and not yet 
              paid).
              
                        (c)  By executing and delivering an Assignment and 
              Acceptance, the assigning Bank thereunder and the assignee 
              thereunder shall be deemed to confirm to and agree with each 
              other and the other parties hereto as follows:  (i) such 
              assigning Bank warrants that it is the legal and beneficial 
              owner of the interest being assigned thereby free and clear 
              of any adverse claim and that its Commitments, and the 
              outstanding balances of its Loans, in each case without 
              giving effect to assignments thereof which have not become 
              effective, are as set forth in such Assignment and 
              Acceptance, (ii) except as set forth in (i) above, such 
              assigning Bank makes no representation or warranty and 
              assumes no responsibility with respect to any statements, 
              warranties or representations made in or in connection with 
              this Agreement, or the execution, legality, validity, 
              enforceability, genuineness, sufficiency or value of this 
              Agreement, any other Loan Document or any other instrument or 
              document furnished pursuant hereto, or the financial 
              condition of the Company or any Subsidiary or the performance 
              or observance by the Company or any Subsidiary of any of its 
              obligations under this Agreement, any other Loan Document or 
              any other instrument or document furnished pursuant hereto; 
              (iii) such assignee represents and warrants that it is 






              legally authorized to enter into such Assignment and 
              Acceptance; (iv) such assignee confirms that it has received 
              a copy of this Agreement, together with copies of the most 
              recent financial statements delivered pursuant to 
              Section 5.05 and such other documents and information as it 
              has deemed appropriate to make its own credit analysis and 
              decision to enter into such Assignment and Acceptance; 
              (v) such assignee will independently and without reliance 
              upon such assigning Bank or any other Bank 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 (vi) such 
              assignee agrees that it will perform in accordance with their 
              terms all the obligations which by the terms of this 
              Agreement are required to be performed by it as a Bank.
              
                        (d)  Upon its receipt of a duly completed 
              Assignment and Acceptance executed by an assigning Bank and 
              an assignee together with the Note or Notes subject to such 
              assignment (if applicable), the assigning Bank shall 
              (i) accept such Assignment and Acceptance and (ii) give 
              prompt notice thereof to the other Banks and the Company.  
              Within five Business Days after receipt of notice, the 
              Company, at its own expense, shall execute and deliver to the 
              assignee, in exchange for the surrendered Note or Notes, if 
              any, a new Note or Notes to the order of such assignee in a 
              principal amount equal to the applicable Commitment assumed 
              by it pursuant to such Assignment and Acceptance and, if the 
              assigning Bank has retained a Commitment, a new Note to 
              replace the old Note, if any, to the order of such assigning 
              Bank in a principal amount equal to the applicable Commitment
