                 AMOUNTS AND TERMS OF THE ADVANCES

Section 2.01  The Advances
--------------------------
  Each Lender severally agrees, on the terms and conditions hereinafter set
forth, to make Advances to the Borrower from time to time on any Business Day
during the period from the date hereof until the Termination Date in an
aggregate amount not to exceed at any time outstanding the amount set
opposite such Lender's name on the signature pages hereof or, if such Lender
has entered into any Assignment and Acceptance, set forth for such Lender in
the Register maintained by the Agent pursuant to Section 8.07(c), as such
amount may be reduced pursuant to Section 2.04 (such Lender's "Commitment"). 
Each Borrowing shall consist of Advances of the same Type made on the same
day by the Lenders ratably according to their respective Commitments.  Each
Borrowing consisting of Eurodollar Rate Advances shall be in an aggregate
amount not less than $10,000,000 or an integral multiple of $1,000,000 in
excess thereof.  Each Borrowing consisting of Base Rate Advances shall be in
an aggregate amount not less than $500,000 or an integral multiple of
$500,000 in excess thereof.  Within the limits of each Lender's Commitment,
the Borrower may from time to time borrow and prepay pursuant to Section
2.10(b); provided, however, that amounts borrowed hereunder, once repaid or
prepaid, may not be reborrowed.

2.02  Making the Advances
-------------------------
  (a)  Each Borrowing shall be made on notice by the Borrower to the Agent,
       given not later than 10:00 A.M. (i) in the case of a Borrowing
       comprising Base Rate Advances, on the date of the proposed
       Borrowing, and (ii) in the case of a Borrowing comprising Eurodollar
       Rate Advances, three Business Days prior to the date of the proposed
       Borrowing.  The Agent shall give to each Lender prompt notice of
       each proposed Borrowing by telecopier, telex or cable.  Each such
       notice from the Borrower of a Borrowing (a "Notice of Borrowing")
       shall be by telecopier, telex or cable, confirmed immediately in
  11
       writing, in substantially the form of Exhibit C-1 hereto, specifying
       therein the requested (A) date of such Borrowing, (B) Type of
       Advances comprising such Borrowing, (C) aggregate amount of such
       Borrowing and (D) in the case of a Borrowing comprising Eurodollar
       Rate Advances, initial Interest Period for each such Advance.  Upon
       fulfillment of the applicable conditions set forth in Article III,
       each Lender shall, before 12:00 Noon on the date of such Borrowing,
       make available for the account of its Applicable Lending Office to
       the Borrower, at the Borrower's Account, in same day funds, such
       Lender's Percentage of such Borrowing.

  (b)  Each Notice of Borrowing shall be irrevocable and binding on the
       Borrower.  In the case of any Borrowing which the related Notice of
       Borrowing specifies is to comprise Eurodollar Rate Advances, the
       Borrower shall indemnify each Lender against any loss, cost or
       expense incurred by such Lender as a result of any failure to
       fulfill on or before the date specified in such Notice of Borrowing
       for such Borrowing the applicable conditions set forth in Article
       III, or as a result of such Borrowing not being completed on the
       proposed date thereof because of a reason attributable to the
       Borrower, including, without limitation, any loss (including loss of
       anticipated profits), cost or expense incurred by reason of the
       liquidation or reemployment of deposits or other funds acquired by
       such Lender to fund the Advance to be made by such Lender as part of
       such Borrowing when such Advance, as a result of such failure, is
       not made on such date.

  (c)  The failure of any Lender to make the Advance to be made by it as
       part of any Borrowing shall not relieve any other Lender of its
       obligation, if any, hereunder to make its Advance on the date of
       such Borrowing, but no Lender shall be responsible for the failure
       of any other Lender to make the  Advance to be made by such other
       Lender on the date of any Borrowing.

2.03  Fees
-----------
  (a)  The Borrower agrees to pay to the Agent for the account of each
       Lender a facility fee on the average daily amount of such Lender's
       Commitment (determined without regard to usage) from the date
       hereof, in the case of each Bank, and from the effective date
       specified in the Assignment and Acceptance pursuant to which it
       became a Lender, in the case of each other Lender, until the
       Termination Date, payable quarterly in arrears on the last day of
       each March, June, September and December during the term of such
       Lender's Commitment, commencing September 30, 1995, and on the
       Termination Date, at the rate of 0.10% per annum.

       provided for in the separate fee letter, dated July 3, 1995, between
       the Guarantor and CSI (the "Fee Letter").

----------------------------------
  (a)  The Borrower shall have the right, upon at least five Business Days'
       notice to the Agent, to terminate in whole or reduce ratably in part
       the unused portions of the respective Commitments of the Lenders;
       provided that each partial reduction shall be in an aggregate amount
       of $5,000,000 or an integral multiple of $1,000,000 in excess
       thereof.

  (b)  On the Termination Date, the Commitments of the Lenders shall be
              reduced to zero.
  12
  (c)  On the date of 
       any repayment or
        prepayment of the principal amount
       of the Advances made hereuder, the Commitments of the Lenders shall
       automatically and permanently reduce ratably by an amount equal to
       the amount 
       so repaid or
        prepaid.

2.05  Repayment of Advances
---------------------------
The Borrower shall repay the principal amount of each Advance made by each
Lender in accordance with the Note to the order of such Lender.




2.06  Interest on Advances
---------------------------
  The Borrower shall pay interest on the unpaid principal amount of each
Advance owing to each Lender from the date of such Advance until such
principal amount shall be paid in full, at the Applicable Rate for such
Advance (except as otherwise provided in this Section 2.06), payable as
follows:

  (a)  Base Rate Advances.  If such Advance is a Base Rate Advance,
       interest thereon shall be payable quarterly in arrears on the last
       day of each March, June, September and December, on the date of any
       Conversion of such Base Rate Advance and on the date such Base Rate
       Advance shall become due and payable or otherwise shall be paid in
       full; provided that at any time an Event of Default shall have
       occurred and be continuing, each Base Rate Advance shall bear
       interest, payable on demand, at a rate per annum equal at all times
       to 2% per annum plus above the Applicable Rate in effect from time
       to time for Base Rate Advances.

  (b)  Eurodollar Rate Advances.  If such Advance is a Eurodollar Rate
       Advance, interest thereon shall be payable on the last day of the
       Interest Period for such Advance and, if such Interest Period has a
       duration of more than three months, on each day which occurs during
       such Interest Period every three months from the first day of such
       Interest Period; provided that at any time an Event of Default shall
       have occurred and be continuing, each Eurodollar Rate Advance shall
       bear interest payable on demand, at a rate per annum equal at all
       times to 2% per annum above the rate per annum required to be paid
       on such Eurodollar Rate Advance immediately prior to the date of the
       occurrence of such Event of Default.

2.07   Additional Interest on Eurodollar Rate Advances
--------------------------------------------------------
  The Borrower shall pay to each Lender, so long as such Lender shall be
required under regulations of the Board of Governors of the Federal Reserve
System to maintain reserves with respect to liabilities or assets consisting
of or including Eurocurrency Liabilities, additional interest on the unpaid
principal amount of each Eurodollar Rate Advance of such Lender, from the
date of such Advance until such principal amount is paid in full, at an
interest rate per annum equal at all times to the remainder obtained by
subtracting (i) the Eurodollar Rate for the Interest Period for such Advance
from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage
equal to 100% minus the Eurodollar Rate Reserve Percentage of such Lender for
such Interest Period, payable on each date on which interest is payable on
such Advance.  Such additional interest shall be determined by such Lender
and notified to the Borrower through the Agent.  If requested by the
Borrower, the Lender requesting such additional interest shall provide a
brief summary of the manner in which such additional interest was determined,
provided that the failure to deliver such summary or, absent manifest error,
the contents of such summary shall not affect the obligation of the Borrower
to pay such additional interest.
  13
2.08   Interest Rate Determination
------------------------------------
  (a)  Each Reference Bank agrees to furnish to the Agent timely
       information for the purpose of determining each Eurodollar Rate.  If
       
       fewer than two
        Reference 
       Banks
        furnish such timely information to
       the Agent for the purpose of determining any such interest rate, the
       Agent shall determine such interest rate on the basis of timely
       information furnished by the remaining Reference Bank.

  (b)  The Agent shall give prompt notice to the Borrower and the Lenders
       of the applicable interest rate determined by the Agent for purposes
       of Section 2.06(a) or (b), and the applicable rate, if any,
       furnished by each Reference Bank for the purpose of determining the
       applicable interest rate under Section 2.06(b).

  (c)  If, with respect to any Eurodollar Rate Advances, (i) the Majority
       Lenders notify the Agent that the Eurodollar Rate for any Interest
       Period for such Advances will not adequately reflect the cost to
       such Majority Lenders of making, funding or maintaining their
       respective Eurodollar Rate Advances for such Interest Period or (ii)
       the Reference Banks notify the Agent that adequate and fair means do
       not exist for ascertaining the applicable interest rate on the basis
       provided for in the definition of Eurodollar Rate, the Agent shall
       forthwith so notify the Borrower and the Lenders, whereupon

       (A)  each Eurodollar Rate Advance will automatically, on the last
            day of the then existing Interest Period therefor, Convert
            into a Base Rate Advance, and

       (B)  the obligation of the Lenders to make, or to Convert Advances
            into, Eurodollar Rate Advances shall be suspended until the
            Agent shall notify the Borrower and the Lenders that the
            circumstances causing such suspension no longer exist.

  (d)  If the Borrower shall fail to (i) select the duration of any
       Interest Period for any Eurodollar Rate Advances in accordance with
       the provisions contained in the definition of  Interest Period  in
       Section 1.01, or (ii) provide a Notice of Conversion with respect to
       any Eurodollar Rate Advances on or prior to 11:00 A.M. on the third
       Business Day prior to the last day of the Interest Period applicable
       thereto, in the case of a Conversion to or in respect of Eurodollar
       Rate Advances, the Agent will forthwith so notify the Borrower and
       the Lenders and such Advances will automatically, on the last day of
       the then existing Interest Period therefor, Convert into Base Rate
       Advances.

  (e)  On the date on which the aggregate unpaid principal amount of
       Advances comprising any 
       Eurodollar Rate Borrowing shall be reduced,
       by payment or prepayment or otherwise, to less than $5,000,000, such
       Advances shall automatically Convert into Base Rate Advances, and on
       and after such date the right of the Borrower to Convert such
       Advances into Eurodollar Rate Advances shall terminate; provided,
       however, that if and so long as each such Advance shall have the
       same Interest Period as Advances comprising another Eurodollar Rate
       Borrowing, and the aggregate unpaid principal amount of all such
       Advances shall equal or exceed $5,000,000,  the Borrower shall have
       the right to continue all such Eurodollar Rate Advances as
       Eurodollar Rate Advances having such Interest Period.

2.09  Voluntary Conversion of Advances
--------------------------------------
  The Borrower may on any Business Day, by delivering a Notice of Conversion
(a "Notice of Conversion") to the Agent not later than 11:00 A.M. on the
third Business Day prior to the date of the proposed Conversion, and subject
to the provisions of Sections 2.08 and 2.12, Convert all Advances of one Type
  14
comprising the same Borrowing into Advances of another Type; provided,
however, that any Conversion of any Eurodollar Rate Advances into Advances of
another Type shall be made on, and only on, the last day of an Interest
Period for such Eurodollar Rate Advances.  Each such Notice of Conversion
shall be in substantially the form of Exhibit C-2 hereto and shall, within
the restrictions specified above, specify (i) the date of such Conversion,
(ii) the Advances to be Converted, (iii) if such Conversion is into
Eurodollar Rate Advances, the duration of the Interest Period for each such
Advance, and (iv) the aggregate amount of Advances proposed to be Converted.

2.10  Prepayments of Advances
-----------------------------
  (a)  The Borrower shall have no right to prepay any principal amount of
       any Advances other than as provided in subsections (b) and (c)
       below.

  (b)  The Borrower may, upon at least two Business Days' notice to the
       Agent stating the proposed date and aggregate principal amount of
       the prepayment, and if such notice is given the Borrower shall,
       prepay the outstanding principal amounts of the Advances comprising
       part of the same Borrowing in whole or ratably in part, together
       with accrued interest to the date of such prepayment on the
       principal amount prepaid; provided, however, that (x) each partial
       prepayment shall be in an aggregate principal amount not less than
       $1,000,000 (or, if lower, the principal amount outstanding hereunder
       on the date of such prepayment) or an integral multiple of
       $1,000,000 in excess thereof and (y) in the case of any such
       prepayment of a Eurodollar Rate Advance on a day other than the last
       day of an Interest Period for such Advance, the Borrower shall be
       obligated to reimburse the Lenders in respect thereof pursuant to
       Section 8.04(b).

  (c)  On the date of any termination or reduction of the Commitments
       pursuant to Section 2.04, the Borrower shall pay or prepay for the
       ratable accounts of the Lenders so much of the principal amount
       outstanding under this Agreement as shall be necessary in order that
       the principal amount outstanding (after giving effect to such
       prepayment) will not exceed the amount of Commitments following such
       termination or reduction, together with (i) accrued interest to the
       date of such prepayment on the principal amount repaid or prepaid
       and (ii) in the case of prepayments of Eurodollar Rate Advances, any
       amount payable to the Lenders pursuant to Section 8.04(b).

2.11  Increased Costs
---------------------
  (a)  If, due to either (i) the introduction of or any change (other than
       any change by way of imposition or increase of reserve requirements,
       in the case of Eurodollar Rate Advances, included in the Eurodollar
       Rate Reserve Percentage) in or in the interpretation of any law or
       regulation or (ii) the compliance with any guideline or request from
       any central bank or other governmental authority (whether or not
       having the force of law), there shall be any increase in the cost to
       any Lender of agreeing to make or making, funding or maintaining
       Eurodollar Rate Advances, then the Borrower shall from time to time,
       upon demand by such Lender (with a copy of such demand to the
       Agent), pay to such Lender additional amounts sufficient to
       compensate such Lender for such increased cost.  Each Lender agrees
       to notify the Borrower of any such increased costs as soon as
       reasonably practicable after determining that such increased cost is
       applicable to Eurodollar Rate Advances hereunder.  A certificate as
       to the amount of such increased cost, submitted to the Borrower and
       the Agent by such Lender, shall be conclusive and binding for all
       purposes, absent manifest error.  If requested by the Borrower, the
       Lender requesting such increased cost shall provide a brief summary
       of the manner in which such increased cost was determined, provided
         15
       that the failure to deliver such summary or, absent manifest error,
       the contents of such summary shall not affect the obligation of the
       Borrower to pay such increased cost.

  (b)  If any Lender determines that compliance with any law or regulation
       or any guideline or request from any central bank or other
       governmental authority (whether or not having the force of law)
       affects or would affect the amount of capital required or expected
       to be maintained by such Lender or any corporation controlling such
       Lender and that the amount of such capital is increased by or based
       upon the existence of such Lender's commitment to lend hereunder and
       other commitments of this type, then, upon demand by such Lender
       (with a copy of such demand to the Agent), the Borrower shall
       immediately pay to such Lender, from time to time as specified by
       such Lender, additional amounts sufficient to compensate such Lender
       or such corporation in the light of such circumstances, to the
       extent that such Lender reasonably determines such increase in
       capital to be allocable to the existence of such Lender's commitment
       to lend hereunder.  Each Lender agrees to notify the Borrower of any
       such additional amount as soon as reasonably practicable after the
       Lender makes such determination.  A certificate as to such amounts
       submitted to the Borrower and the Agent by such Lender shall be
       conclusive and binding for all purposes, absent manifest error.  If
       requested by the Borrower, the Lender requesting such additional
       amount shall provide a brief summary of the manner in which such
       additional amount was determined, provided that the failure to
       deliver such summary or, absent manifest error, the contents of such
       summary shall not affect the obligation of the Borrower to pay such
       additional amount.

  (c)  The provisions contained in this Section 2.11 shall survive for a
       period of 90 days after the repayment (on or after the Termination
       Date) of all Advances.

2.12  Illegality
--------------
Notwithstanding any other provision of this Agreement, if any Lender shall
notify the Agent that the introduction of or any change in or in the
interpretation of any law or regulation makes it unlawful, or any central
bank or other governmental authority asserts that it is unlawful, for any
Lender or its Eurodollar Lending Office to perform its obligations hereunder
to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate
Advances hereunder, (i) the obligation of the Lenders to make, or to Convert
Advances into, Eurodollar Rate Advances shall be suspended until the Agent
(based on notice from the affected Lender) shall notify the Borrower and the
Lenders that the circumstances causing such suspension no longer exist and
(ii) the Borrower shall forthwith prepay in full all Eurodollar Rate Advances
of all Lenders then outstanding, together with interest accrued thereon,
unless the Borrower, within five Business Days of notice from the Agent (or
such shorter, maximum period of time, specified by the Agent, as may be
legally allowable), Converts all Eurodollar Rate Advances of all Lenders then
outstanding into Base Rate Advances in accordance with Section 2.09.

2.13  Payments and Computations
-------------------------------
  (a)  The Borrower shall make each payment hereunder and under the Notes
       not later than 12:00 Noon on the day when due in U.S. dollars to the
       Agent at its address referred to in Section 8.02 in same day funds. 
       The Agent will promptly thereafter cause to be distributed like
       funds relating to the payment of principal or interest or facility
       fees ratably (other than amounts payable pursuant to Section 2.07)
       to the Lenders for the account of their respective Applicable
       Lending Offices, and like funds relating to the payment of any other
       amount payable to any Lender to such Lender for the account of its
       Applicable Lending Office, in each case to be applied in accordance
         16
       with the terms of this Agreement.  Upon its acceptance of an
       Assignment and Acceptance and recording of the information contained
       therein in the Register pursuant to Section 8.07(d), from and after
       the effective date specified in such Assignment and Acceptance, the
       Agent shall make all payments hereunder and under the Notes in
       respect of the interest assigned thereby to the Lender assignee
       thereunder, and the parties to such Assignment and Acceptance shall
       make all appropriate adjustments in such payments for periods prior
       to such effective date directly between themselves.

  (b)  The Borrower hereby authorizes each Lender, if and to the extent
       payment owed to such Lender is not made to the Agent when due
       hereunder or under any Note held by such Lender, to charge from time
       to time against any or all of the Borrower's accounts with such
       Lender any amount so due.

  (c)  All computations of interest based on the Base Rate shall be made by
       the Agent on the basis of a year of 365 or 366 days, as the case may
       be, and all computations of interest based on the Eurodollar Rate
       and of facility fees shall be made by the Agent, and all
       computations of interest pursuant to Section 2.07 shall be made by a
       Lender, on the basis of a year of 360 days, in each case for the
       actual number of days (including the first day but excluding the
       last day) occurring in the period for which such interest or
       facility fees are payable.  Each determination by the Agent (or, in
       the case of Section 2.07, by a Lender) of an interest rate hereunder
       shall be conclusive and binding for all purposes, absent manifest
       error.

  (d)  Whenever any payment hereunder or under the Notes shall be stated to
       be due on a day other than a Business Day, such payment shall be
       made on the next succeeding Business Day, and such extension of time
       shall in such case be included in the computation of payment of
       interest or facility fees, as the case may be; provided, however,
       that if such extension would cause payment of interest on or
       principal of Eurodollar Rate Advances to be made in the next
       following calendar month, such payment shall be made on the next
       preceding Business Day.

  (e)  Unless the Agent shall have received notice from the Borrower prior
       to the date on which any payment is due to the Lenders hereunder
       that the Borrower will not make such payment in full, the Agent may
       assume that the Borrower has made such payment in full to the Agent
       on such date and the Agent may, in reliance upon such assumption,
       cause to be distributed to each Lender on such due date an amount
       equal to the amount then due such Lender.  If and to the extent that
       the Borrower shall not have so made such payment in full to the
       Agent, each Lender shall repay to the Agent forthwith on demand such
       Lender's pro rata share of such deficiency together with interest
       thereon, for each day from the date such amount is distributed to
       such Lender until the date such Lender repays such amount to the
       Agent, at the Federal Funds Rate.

2.14  Taxes
-----------
  (a)  Any and all payments by the Borrower hereunder and under the Notes
       shall be made, in accordance with Section 2.13, free and clear of
       and without deduction for any and all present or future taxes,
       levies, imposts, deductions, charges or withholdings, and all
       liabilities with respect thereto, excluding, in the case of each
       Lender and the Agent, taxes imposed on its overall net income, and
       franchise taxes imposed on it by the jurisdiction under the laws of
       which such Lender or the Agent (as the case may be) is organized or
       any political subdivision thereof and, in the case of each Lender,
       taxes imposed on its overall net income, and franchise taxes imposed
         17
       on it by the jurisdiction of such Lender's Applicable Lending Office
       or any political subdivision thereof (all such non-excluded taxes,
       levies, imposts, deductions, charges, withholdings and liabilities
       being hereinafter referred to as "Taxes").  If the Borrower shall be
       required by law to deduct any Taxes from or in respect of any sum
       payable hereunder or under any Note to any Lender or the Agent,
       (i) the sum payable shall be increased as may be necessary so that
       after making all required deductions (including deductions
       applicable to additional sums payable under this Section 2.14) such
       Lender or the Agent (as the case may be) receives an amount equal to
       the sum it would have received had no such deductions been made,
       (i) the Borrower shall make such deductions and (ii) the Borrower
       shall pay the full amount deducted to the relevant taxation
       authority or other authority in accordance with applicable law.

  (b)  In addition, the Borrower agrees to pay any present or future stamp
       or documentary taxes or any other excise or property taxes, charges
       or similar levies which arise from any payment made hereunder or
       under the Notes or from the execution, delivery or registration of,
       or otherwise with respect to, this Agreement or the Notes
       (hereinafter referred to as "Other Taxes").

  (c)  The Borrower will indemnify each Lender and the Agent for the full
       amount of Taxes or Other Taxes (including, without limitation, any
       Taxes or Other Taxes imposed by any jurisdiction on amounts payable
       under this Section 2.14) paid by such Lender or the Agent (as the
       case may be) and any liability (including penalties, interest and
       expenses) arising therefrom or with respect thereto, whether or not
       such Taxes or Other Taxes were correctly or legally asserted.  This
       indemnification shall be made within 30 days from the date such
       Lender or the Agent (as the case may be) makes written demand
       therefor.  Nothing herein shall preclude the right of the Borrower
       to contest any such Taxes or Other Taxes so paid, and the Lenders in
       question or the Agent (as the case may be) will, following notice
       from, and at the expense of, the Borrower, reasonably cooperate with
       the Borrower to preserve the Borrower's rights to contest such Taxes
       or Other Taxes.

  (d)  Within 30 days after the date of any payment of Taxes, the Borrower
       will furnish to the Agent, at its address referred to in Section
       8.02, the original or a certified copy of a receipt evidencing
       payment thereof.

  (e)  Each Lender agrees that, on or prior to the date upon which it shall
       become a party hereto, and upon the reasonable request from time to
       time of the Borrower or the Agent, such Lender will deliver to the
       Borrower and the Agent either (i) a statement that it is organized
       under the laws of a jurisdiction within the United States or (ii)
       duly completed copies of such form or forms as may from time to time
       be prescribed by the United States Internal Revenue Service
       indicating that such Lender is entitled to receive payments without
       deduction or withholding of any United States federal income taxes,
       as permitted by the Code.  Each Lender represents and warrants that
       each such form delivered by it to the Agent and the Borrower
       pursuant to this subsection (e) is or will be, as the case may be,
       complete and accurate at the time delivered.  Each Lender that
       delivers to the Borrower and the Agent the form or forms referred to
       in clause (ii), above, further undertakes to deliver to the Borrower
       and the Agent further copies of such form or forms, or successor
       applicable form or forms, as the case may be, as and when any
       previous form filed by it hereunder shall expire or shall become
       incomplete or inaccurate in any respect. 

  (f)  Any Lender claiming any additional amounts payable pursuant to this
       Section 2.14 shall use its best efforts (consistent with its
  18
       internal policy and legal and regulatory restrictions) to change the
       jurisdiction of its Applicable Lending Office if the making of such
       additional amounts which may thereafter accrue an rof such Lender, 
       be otherwise such Lender.

  (g)  Without prejudice to the survival of any other agreement of the
       Borrower hereunder, the agreements and obligations of the contained in
       this Section 2.14 shall survive for a period of four years after the
       payment in full of principal and interest hereunder and under the Notes.

2.15  Sharing of Payments, Etc
------------------------------
  If any Lender shall obtain any payment (whether voluntary, involuntary,
through the exercise of any right of set-off, or otherwise) on account of the
Advances made by it (other than pursuant to Section 2.07, 2.11 or 8.04(b)) in
excess of its ratable share of payments on account of the Advances obtained
by all the Lenders, such Lender shall, if such payment relates to principal
of or interest on an Advance, forthwith purchase from the other Lenders such
participations in the Advances made by them as shall be necessary to cause
such purchasing Lender to share the excess payment ratably with each of them,
provided, however, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Lender, such purchase from each
Lender shall be rescinded and each such Lender shall repay to the purchasing
Lender the purchase price to the extent of such recovery, together with an
amount equal to such Lender's ratable share (according to the proportion of
(i) the amount of such Lender's required repayment to (ii) the total amount
so recovered from the purchasing Lender) of any interest or other amount paid
or payable by the purchasing Lender in respect of the total amount so
recovered.  The Borrower agrees that any Lender so purchasing a participation
from another Lender pursuant to this Section 2.15 may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of
set-off) with respect to such participation as fully as if such Lender were
the direct creditor of the Borrower in the amount of such participation.  If
such excess payment relates to any fees payable hereunder (other than the
fees specified in Section 2.03(b) hereof), the Lender receiving such excess
payment shall forthwith remit such excess payment to the Agent for
distribution by the Agent to the Lenders on a pro rata basis, provided,
however, that if all or any portion of such excess payment is thereafter
recovered from such receiving Lender, each Lender shall remit to the Agent
for redistribution to the receiving Lender such Lender's ratable share of the
amount so recovered together with an amount equal to such Lender's ratable
share of any interest or other amount paid or payable by the receiving Lender
in respect of the total amount so recovered.

  (a)  Each Loan Party and each of their respective Subsidiaries is a
       corporation duly organized, validly existing and in good standing
       under the laws of the jurisdiction of its incorporation and is duly
       qualified to do business in, and is in good standing in, all other
       jurisdictions where the nature of its business or the nature of
       property owned or used by it makes such qualification necessary. 
       Each Loan Party and each of their respective Subsidiaries has all
       requisite corporate powers and authority to own or lease and operate
       its properties and to carry on its business as now conducted and as
       proposed to be conducted.

  (b)  The execution, delivery and performance by each Loan Party of each
       Loan Document to which such Loan Party is a party are within such
       Loan Party s corporate powers, have been duly authorized by all
       necessary corporate action, do not contravene (i) such Loan Party s
       charter or by-laws, (ii) any law, rule or regulation applicable to
       such Loan Party or (iii) any contractual or legal restriction
       binding on or affecting such Loan Party, and will not result in or
       require the imposition of any lien or encumbrance on, or security
       interest in, any property (including, without limitation, accounts
       or contract rights) of such Loan Party.

  (c)  No Governmental Approval is required for the execution or delivery
       by any Loan Party of any Loan Document to which such Loan Party is a
       party or for the performance by such Loan Party of its obligations
       under any such Loan Document.

  (d)  This Agreement is, and the Notes when executed and delivered
       hereunder will be, legal, valid and binding obligations of the
       Borrower enforceable against the Borrower in accordance with their
       respective terms.  The Guaranty is the legal, valid and binding
       obligation of the Guarantor enforceable against the Guarantor in
       accordance with its terms.

  (e)  Each of the audited consolidated balance sheet of the Guarantor and
       its Subsidiaries as at December 31, 1994, and the related statements
       of income, retained earnings and cash flows of the Guarantor and its
       Subsidiaries for the fiscal year then ended, and the unaudited
       consolidated balance sheet of the Guarantor and its Subsidiaries as
       at March 31, 1995, and the related statements of income, retained
       earnings and cash flows of the Guarantor and its Subsidiaries for
       the three months then ended, copies of which have been furnished to
       each Bank, fairly present the financial condition of the Guarantor
       and its Subsidiaries as at such dates and the results of the
       operations of the Guarantor and its Subsidiaries for the periods
       ended on such dates, all in accordance with generally accepted
       accounting principles consistently applied.  Since December 31,
       1994, there has been no material adverse change in such condition or
       results of operations, in the prospects of the Guarantor and its
       Subsidiaries or of the Borrower, or in the ability of any Loan Party
       to perform its obligations under any Loan Document to which such
       Loan Party is a party.

  (f)  There is no pending or threatened action or proceeding affecting any
       Loan Party or any of their respective Subsidiaries before any court,
       governmental agency or arbitrator, that could, if adversely
       determined, reasonably be expected to materially adversely affect
       the financial condition, results of operations, operations or
       prospects of any Loan Party or any of their respective Subsidiaries
       or which purports to affect the legality, validity or enforceability
       of any Loan Document.

  (g)  The use of the proceeds of each Advance will comply with all
       provisions of applicable law and regulation in all material
              respects.
  22

  (h)  Each Loan Party and each of their respective Subsidiaries has filed
       all tax returns (Federal, state and local) required to be filed and
       paid all taxes shown thereon to be due, including interest and
       penalties, except to the extent that any such Loan Party or
       Subsidiary is diligently contesting any such taxes in good faith and
       by appropriate proceedings, and for which adequate reserves for
       payment thereof have been established.

  (i)  The Guarantor is the direct, legal and beneficial owner of 100% of
       the issued and outstanding capital stock of Wisconsin Gas Company,
       Sta-Rite Industries, Inc. and the Borrower.

  (j)  Neither Loan Party nor any of their respective Subsidiaries is an
        investment company  or a company  controlled  by an  investment
       company , within the meaning of the Investment Company Act of 1940,
       as amended.

  (k)  The Guarantor is a  holding company  exempt from registration under
       Section 5 of the Public Utility Holding Company Act of 1935, as
       amended ( PUHCA ), pursuant to Section 3(a)(1) of such Act.  The
       Borrower is not a  holding company  within the meaning of PUHCA.

  (l)  Neither Loan Party is engaged in the business of extending credit
       for the purpose of buying or carrying margin stock (within the
       meaning of Regulation U issued by the Board of Governors of the
       Federal Reserve System), and no proceeds of any Advance will be used
       to buy or carry any margin stock or to extend credit to others for
       the purpose of buying or carrying any margin stock.

  (m)  No ERISA Event has occurred or is reasonably expected to occur with
       respect to any Plan which reasonably could be expected to materially
       adversely affect the financial condition, results of operations,
       operations or prospects of the Borrower and its Subsidiaries or the
       ability of the Borrower to perform its obligations hereunder.  Since
       the actuarial valuation date specified in the most recent Schedule B
       (Actuarial Information) to the annual report of Plans maintained by
       the Borrower (Form 5500 Series), if any, (i) there has been no
       material adverse change in the funding status of the Plans referred
       to therein which reasonably could be expected to materially
       adversely affect the financial condition, results of operations,
       operations or prospects of the Borrower and its Subsidiaries or the
       ability of the Borrower to perform its obligations hereunder and
       (ii) no  prohibited transaction  has occurred with respect thereto
       which is reasonably expected to result in a material liability to
       the Borrower.  Neither the Borrower nor any of its ERISA Affiliates
       has incurred nor reasonably expects to incur any material withdrawal
       liability under ERISA to any Multiemployer Plan.

  (n)  Each Loan Party and their respective Subsidiaries are in compliance
       in all material respects with all applicable Federal, state and
       local statutes, rules, regulations, orders and other provisions of
       law relating to Hazardous Materials, air emissions, water discharge,
       noise emission and liquid disposal, and other environmental, health
       and safety matters, other than those the non-compliance with which
       would not have a material adverse effect (taking into consideration
       all fines, penalties and sanctions that may be imposed because of
       such non-compliance) on the condition (financial or otherwise),
       results of operations, operations or prospects of the Guarantor or
       any of its Subsidiaries or on the ability of any Loan Party to
       perform its obligations under any Loan Document to which such Loan
       Party is a party.  Except as disclosed in the financial statements
       described in Section 4.01(e), neither Loan Party nor any of their
       respective Subsidiaries has received from any governmental authority
       any notice of any material violation of any such statute, rule,
              regulation, order or provision.

  automatically become and be due and payable, without presentment, demand,
  protest or any notice of any kind, all of which are hereby expressly
  waived by the Borrower.


                            ARTICLE VII

                             THE AGENT

Section 7.01 Authorization and Action
-------------------------------------
  Each Lender hereby appoints and authorizes the Agent to take such action
as agent on its behalf and to exercise such powers under this Agreement as
are delegated to the Agent by the terms hereof, together with such powers as
are reasonably incidental thereto.  As to any matters not expressly provided
for by this Agreement (including, without limitation, enforcement or
collection of the Notes and the Guaranty), the Agent shall not be required to
exercise any discretion or take any action, but shall be required to act or
to refrain from acting (and shall be fully protected in so acting or
refraining from acting) upon the instructions of the Majority Lenders, and
such instructions shall be binding upon all Lenders and all holders of Notes;
provided, however, that the Agent shall not be required to take any action
which exposes the Agent to personal liability or which is contrary to this
Agreement or applicable law.  The Agent agrees to give to each Lender prompt
notice of each notice given to it by the Borrower pursuant to the terms of
this Agreement.

7.02  Agent's Reliance, Etc.
----------------------------
  Neither the Agent nor any of its directors, officers, agents or employees
shall be liable for any action taken or omitted to be taken by it or them
under or in connection with this Agreement, except for its or their own gross
negligence or willful misconduct. Without limitation of the generality of the
foregoing, the Agent:  (i) to the extent of any payments to be disbursed by
the Agent, may treat the payee of any Note as the holder thereof until the
Agent receives and accepts an Assignment and Acceptance entered into by the
Lender which is the payee of such Note, as assignor, and an assignee of such
Lender, as provided in Section 8.07; (ii) may consult with legal counsel
(including counsel for the Borrower), independent public accountants and
other experts selected by it and shall not be liable for any action taken or
omitted to be taken in good faith by it in accordance with the advice of such
counsel, accountants or experts; (iii) makes no warranty or representation to
any Lender and shall not be responsible to any Lender for any statements,
warranties or representations (whether written or oral) made in or in
connection with this Agreement; (iv) shall not have any duty to ascertain or
to inquire as to the performance or observance of any of the terms, covenants
or conditions of this Agreement on the part of the Borrower or to inspect the
property (including the books and records) of the Borrower; (v) shall not be
responsible to any Lender for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of this Agreement or any
other instrument or document furnished pursuant hereto; and (vi) shall incur
no liability under or in respect of this Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by
telecopier, telegram, cable or telex) believed by it to be genuine and signed
or sent by the proper party or parties.

7.03 Citibank and Affiliates
----------------------------
  With respect to its Commitment, the Advances made by it and the Notes
issued to it, Citibank shall have the same rights and powers under this
Agreement as any other Lender and may exercise the same as though it were not
the Agent; and the terms "Bank" or "Banks" and "Lender" or "Lenders" shall,
unless otherwise expressly indicated, include Citibank in its individual
capacity.  Citibank and its Affiliates may accept deposits from, lend money
to, act as trustee under indentures of, and generally engage in any kind of
business with, the Borrower, any of its Subsidiaries or Affiliates and any
Person who may do business with or own securities of the Borrower or any such
Subsidiary or Affiliate, all as if Citibank were not the Agent and without
any duty to account therefor to the Lenders.

7.04 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
referred to in Section 4.01(e) and such other documents and information as it
has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement.  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.

7.05 Indemnification
--------------------
  The Lenders agree to indemnify the Agent (to the extent not reimbursed by
the Borrower), ratably according to the respective principal amounts of the
Notes then held by each of them (or if no Notes are at the time outstanding
or if any Notes are held by Persons which are not Lenders, ratably according
to the respective amounts of their Commitments), from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever
  31
which may be imposed on, incurred by, or asserted against the Agent in any
way relating to or arising out of this Agreement or any action taken or
omitted by the Agent under this Agreement, provided that no Lender shall be
liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the Agent's gross negligence or willful misconduct.  Without
limitation of the foregoing, each Lender agrees to reimburse the Agent
promptly upon demand for its ratable share of any out-of-pocket expenses
(including counsel fees) incurred by the Agent in connection with the
preparation, execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings or otherwise)
of, or legal advice in respect of rights or responsibilities under, this
Agreement, to the extent that the Agent is not reimbursed for such expenses
by the Borrower, provided, that no Lender shall be liable for any portion of
such out-of-pocket expenses (including counsel fees) resulting from the
Agent's gross negligence or willful misconduct.

7.06 Successor Agent
--------------------
  The Agent may resign at any time by giving written notice thereof to the
Lenders and the Borrower and may be removed at any time with or without cause
by the Majority Lenders, with any such resignation or removal to become
effective only upon the appointment of a successor Agent pursuant to this
Section 7.06.  Upon any such resignation or removal, the Majority Lenders
shall have the right to appoint a successor Agent.  Such successor shall be
subject to the approval of the Borrower, such approval not to be unreasonably
withheld or delayed, provided that such approval shall not be necessary if at
the time such successor is appointed there shall have occurred and be
continuing an Event of Default or an Unmatured Default.  If no successor
Agent shall have been so appointed by the Majority Lenders, and shall have
accepted such appointment, within 30 days after the retiring Agent's giving
of notice of resignation or the Majority Lenders' removal of the retiring
Agent, then the retiring Agent may, on behalf of the Lenders, appoint a
successor Agent, which shall be a Lender or shall be another commercial bank
or trust company organized under the laws of the United States of America or
of any State thereof and having a combined capital and surplus 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 retiring
Agent, and the retiring Agent shall be discharged from its duties and
obligations under this Agreement.  After any retiring Agent's resignation or
removal hereunder as Agent, the provisions of this Article VII shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Agent under this Agreement.


                           ARTICLE VIII

Section 8.01 Amendments, Etc 
----------------------------
  No amendment or waiver of any provision of this Agreement or the Notes,

effective unless the same shall be in writing and signed by the Majority
Lenders, and then such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given; provided,
however,, that no amendment, waiver or consent shall, unless in writing and
signed by all the Lenders, do any of the following:  (a) waive, modify or

and provided, further, that no amendment, waiver or consent shall, unless in
writing and signed by the Agent in addition to the Lenders required above to
take such action, affect the rights or duties of the Agent under this
Agreement or any Note.

Agent pursuant to Article II or VII shall not be effective until received by
the Agent.

8.03 No Waiver; Remedies
------------------------
  No failure on the part of any Lender or the Agent to exercise, and no
delay in exercising, any right under any Loan Document or under any Note
shall operate as a waiver thereof; nor shall any single or partial exercise
of any such right preclude any other or further exercise thereof or the
exercise of any other right.  The remedies herein provided are cumulative and
not exclusive of any remedies provided by law.

8.04 Costs, Expenses, Taxes and Indemnification
-----------------------------------------------
  (a)  The Borrower agrees to pay on demand all costs and expenses in
       connection with the preparation, execution, delivery,
       administration, modification and amendment of the Loan Documents and
       the other documents to be delivered hereunder and thereunder,
       including, without limitation, the reasonable fees and out-of-pocket
       expenses of counsel for the Agent with respect thereto and with
       respect to advising the Agent as to its rights and responsibilities
       under this Agreement.  The Borrower further agrees to pay on demand
       all costs and expenses, if any (including, without limitation,
       reasonable counsel fees and expenses), in connection with the
       enforcement (whether through negotiations, legal proceedings or
       otherwise) of the Loan Documents and the other documents to be
       delivered hereunder and thereunder, including, without limitation,
       reasonable counsel fees and expenses in connection with the
       enforcement of rights under this Section 8.04(a).  In addition, the
       Borrower shall pay any and all stamp and other taxes payable or
       determined to be payable in connection with the execution and
       delivery of the Loan Documents and the other documents to be
       delivered hereunder and thereunder, and agrees to save the Agent and
       each Lender harmless from and against any and all liabilities with
       respect to or resulting from any delay by the Borrower in paying or
              omission to pay such taxes.  
  33

  (b)  If any payment of principal of, or Conversion of, any Eurodollar
       Rate Advance is made other than on the last day of the Interest
       Period for such Advance, as a result of a payment or Conversion
       pursuant to Section 2.08(e), 2.09, 2.10 or 2.12 or acceleration of
       the maturity of the Notes pursuant to Section 6.01 or for any other
       reason, the Borrower shall, upon demand by any Lender (with a copy
       of such demand to the Agent), pay to the Agent for the account of
       such Lender any amounts required to compensate such Lender for any
       additional losses, costs or expenses which it may reasonably incur
       as a result of such payment or Conversion, including, without
       limitation, any loss (including loss of anticipated profits), cost
       or expense incurred by reason of the liquidation or reemployment of
       deposits or other funds acquired by any Lender to fund or maintain
       such Advance.

  (c)  The Borrower hereby agrees to indemnify and hold each Lender, the
       Agent and their respective officers, directors, employees, agents,
       professional advisors and affiliates (each, an "Indemnified
       Person" ) harmless from and against any and all claims, damages,
       losses, liabilities, costs or expenses (including, without
       limitation, reasonable attorney's fees and expenses, whether or not
       such Indemnified Person is named as a party to any proceeding or is
       otherwise subjected to judicial or legal process arising from any
       such proceeding) (collectively, "Claims") which any of them may
       incur or which may be claimed against any of them by any Person
       (except for Claims resulting from such Indemnified Person's gross
       negligence or willful misconduct):

       (i)  by reason of or in connection with the execution, delivery or
            performance of any Loan Document or any transaction
            contemplated hereby or thereby, or the use by the Borrower or
            any of its Subsidiaries of the proceeds of any Advance;

       (ii) in connection with any documentary taxes, assessments or
            charges made by any governmental authority by reason of the
            execution and delivery of any Loan Document; or

       (iii)      in connection with or resulting from the utilization, storage,
                  disposal, treatment, generation, transportation, release or
                  ownership of any Hazardous Materials (A) at, upon, or under
                  any property of the Borrower or any of its Affiliates or (B)
                  by or on behalf of the Borrower or any of its Affiliates at
                  any time and in any place.

Each Indemnified Person agrees to use reasonable efforts, consistent with
such Indemnified Person s customary business practices and business judgment,
to defend against or mitigate, as appropriate, any Claims.  Each Indemnified
Person further agrees to provide prompt notice to the Borrower of any Claims,
provided, however, that any failure to provide such notice will not affect or
reduce the Borrower s obligations under this subsection (c).

  (d)  The Borrower's obligations under this Section 8.04 shall survive the
repayment of all amounts owing to the Lenders under the Notes and the
termination of the Commitments.  If and to the extent that the obligations of
the Borrower under this Section 8.04 are unenforceable for any reason, the
Borrower agrees to make the maximum contribution to the payment and
satisfaction thereof which is permissible under applicable law.

8.05 Right of Set-off
---------------------
  (a)  Upon (i) the occurrence and during the continuance of any Event of
       Default and (ii) the making of the request or the granting of the
       consent specified by Section 6.01 to authorize the Agent to declare
       the Notes due and payable pursuant to the provisions of Section
  34
       6.01, each Lender 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 Lender to or for the credit or the account of the
       Borrower against any and all of the obligations of the Borrower now
       or hereafter existing under this Agreement and any Note held by such
       Lender, whether or not such Lender shall have made any demand under
       this Agreement or such Note and although such obligations may be
       unmatured.  Each Lender agrees promptly to notify the Borrower after
       any such set-off and application made by such Lender, provided that
       the failure to give such notice shall not affect the validity of
       such set-off and application.  The rights of each Lender under this
       Section are in addition to other rights and remedies (including,
       without limitation, other rights of set-off) which such Lender may
       have.

  (b)  The Borrower agrees that it shall have no right of set-off,
       deduction or counterclaim in respect of its obligations hereunder,
       and that the obligations of the Lenders hereunder are several and
       not joint.  Nothing contained herein shall constitute a
       relinquishment or waiver of the Borrower's rights to any claim
       arising under this Agreement that the Borrower may have against the
       Agent or any Lender for the Agent's or such Lender's, as the case
       may be, gross negligence or wilful misconduct, but no Lender shall
       be liable to the Borrower for the conduct of the Agent or any other
       Lender, and the Agent shall not be liable to the Borrower for the
       conduct of any Lender.

8.06 Binding Effect
-------------------
  This Agreement shall become effective when it shall have been executed by
the Borrower and the Agent and when the Agent shall have been notified in
writing by each Bank that such Bank has executed it and thereafter shall be
binding upon and inure to the benefit of the Borrower, the Agent and each
Lender and their respective successors and assigns, except that the Borrower
shall not have the right to assign its rights or obligations hereunder or any
interest herein without the prior written consent of the Lenders, other than
in connection with a merger of Hypro with and into the Borrower with Hypro as
the surviving corporation assuming all the rights and obligations of the
Borrower hereunder.

8.07 Assignments and Participations
-----------------------------------
  (a)  Each Lender may assign to one or more banks or financial
       institutions all or a portion of its rights and obligations under
       the Loan Documents (including, without limitation, all or a portion
       of its Commitment, the Advances owing to it and the Note or Notes
       held by it); provided, however, that (i) the Borrower shall have
       consented to such assignment (such consent not to be unreasonably
       withheld or delayed) by signing the Assignment and Acceptance
       referred to in clause (iii) below, (ii) each such assignment shall
       be of a constant, and not a varying, percentage of all of the
       assigning Lender's rights and obligations under this Agreement and
       (iii) the parties to each such assignment shall execute and deliver
       to the Agent, for its acceptance and recording in the Register, an
       Assignment and Acceptance, together with any Note or Notes subject
       to such assignment and a processing and recordation fee of $3000
       (plus an amount equal to out-of-pocket legal expenses of the Agent,
       estimated by the Agent and advised to such parties), payable by the
       assigning Lender or the assignee, as agreed upon by such parties. 
       Upon such execution, delivery, acceptance and recording, from and
       after the effective date specified in each Assignment and
       Acceptance, (x) the assignee thereunder shall be a party hereto and,
       to the extent that rights and obligations hereunder have been
  35
       assigned to it pursuant to such Assignment and Acceptance, have the
       rights and obligations of a Lender hereunder and (y) the Lender
       assignor thereunder shall, to the extent that rights and obligations
       hereunder have been assigned by it pursuant to such Assignment and
       Acceptance, relinquish its rights and 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
       Lender's rights and obligations under this Agreement, such Lender
       shall cease to be a party hereto).  Notwithstanding anything to the
       contrary contained in this Agreement, any Lender may at any time
       assign all or any portion of the Advances owing to it to any
       Affiliate of such Lender.  No such assignment, other than to an
       Affiliate of such Lender consented to by the Borrower (such consent
       not to be unreasonably withheld or delayed), shall release the
       assigning Lender from its obligations hereunder.

  (b)  By executing and delivering an Assignment and Acceptance, the Lender
       assignor thereunder and the assignee thereunder confirm to and agree
       with each other and the other parties hereto as follows:  (i) other
       than as provided in such Assignment and Acceptance, such assigning
       Lender makes no representation or warranty and assumes no
       responsibility with respect to any statements, warranties or
       representations made in or in connection with any Loan Document or
       the execution, legality, validity, enforceability, genuineness,
       sufficiency or value of any Loan Document or any other instrument or
       document furnished pursuant hereto; (ii) such assigning Lender makes
       no representation or warranty and assumes no responsibility with
       respect to the financial condition of any Loan Party or the
       performance or observance by any Loan Party of any of its
       obligations under any Loan Document or any other instrument or
       document furnished pursuant hereto or thereto; (iii) such assignee
       confirms that it has received a copy of this Agreement and the
       Guaranty, together with copies of the financial statements referred
       to in Section 4.01(e) 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; (iv) such assignee
       will, independently and without reliance upon the Agent, such
       assigning Lender 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; (v) such assignee appoints and authorizes the Agent
       to take such action as agent on its behalf and to exercise such
       powers under this Agreement as are delegated to the Agent by the
       terms hereof, together with such powers as are reasonably incidental
       thereto; and (vi) such assignee agrees that it will perform in
       accordance with their terms all of the obligations which by the
       terms of this Agreement are required to be performed by it as a
       Lender.

  (c)  The Agent shall maintain at its address referred to in Section 8.02
       a copy of each Assignment and Acceptance delivered to and accepted
       by it and a register for the recordation of the names and addresses
       of the Lenders and the Commitment of, and principal amount of the
       Advances owing to, each Lender from time to time (the "Register"). 
       The entries in the Register shall be conclusive and binding for all
       purposes, absent manifest error, and the Borrower, the Agent and the
       Lenders may treat each Person whose name is recorded in the Register
       as a Lender hereunder for all purposes of this Agreement.  The
       Register shall be available for inspection by the Borrower or any
       Lender at any reasonable time and from time to time upon reasonable
              prior notice.
  36

  (d)  Upon its receipt of an Assignment and Acceptance executed by an
       assigning Lender and an assignee, together with any Note or Notes
       subject to such assignment, the Agent shall, if such Assignment and
       Acceptance has been completed and is in substantially the form of
       Exhibit D hereto, and has been signed by the Borrower, (i) accept
       such Assignment and Acceptance, (ii) record the information
       contained therein in the Register and (iii) give prompt notice of
       such recordation to the Borrower.  Within five Business Days after
       its receipt of such notice, the Borrower, at its own expense, shall
       execute and deliver to the Agent in exchange for the surrendered
       Note or Notes a new Note to the order of such assignee in an amount
       equal to the Commitment assumed by it pursuant to such Assignment
       and Acceptance and, if the assigning Lender has retained a
       Commitment hereunder, a new Note to the order of the assigning
       Lender in an amount equal to the Commitment retained by it
       hereunder.  Such new Note or Notes shall be in an aggregate
       principal amount equal to the aggregate principal amount of such
       surrendered Note or Notes, shall be dated the effective date of such
       Assignment and Acceptance and shall otherwise be in substantially
       the form of Exhibit A hereto.

  (e)  Each Lender may sell participations to one or more banks, financial
       institutions or other entities in all or a portion of its rights and
       obligations under the Loan Documents (including, without limitation,
       all or a portion of its Commitment, the Advances owing to it and the
       Note or Notes held by it); provided, however, that (i) such Lender's
       obligations under this Agreement (including, without limitation, its
       Commitment to the Borrower hereunder) shall remain unchanged,
       (ii) such Lender shall remain solely responsible to the other
       parties hereto for the performance of such obligations, (iii) such
       Lender shall remain the holder of any such Note for all purposes of
       this Agreement, and (iv) the Borrower, the Agent and the other
       Lenders shall continue to deal solely and directly with such Lender
       in connection with such Lender's rights and obligations under this
       Agreement.  The Borrower agrees that any purchaser of a
       participation may, to the fullest extent permitted by law, exercise
       all of its rights of payment (including the right of set-off) with
       respect to such participation as fully as if such purchaser were the
       direct creditor of the Borrower in the amount of such participation.

  (f)  Any Lender may, in connection with any assignment or participation
       or proposed assignment or participation pursuant to this Section
       8.07, disclose to the assignee or participant or proposed assignee
       or participant, any information relating to the Borrower furnished
       to such Lender by or on behalf of the Borrower; provided that, prior
       to any such disclosure, the assignee or participant or proposed
       assignee or participant shall agree to preserve the confidentiality
       of any confidential information relating to the Borrower received by
       it from such Lender.

  (g)  Anything in this Section 8.07 to the contrary notwithstanding, any
Lender may assign and pledge all or any portion of its Commitment and the
Advances owing to it to any Federal Reserve Bank (and its transferees) as
collateral security pursuant to Regulation A of the Board of Governors of the
Federal Reserve System and any Operating Circular issued by such Federal
Reserve Bank.  No such assignment shall release the assigning Lender from its
obligations hereunder.  

8.08 Consent to Jurisdiction
----------------------------
  The Borrower hereby irrevocably submits to the non-exclusive jurisdiction
of any New York State or Federal court sitting in New York County, State of
New York, for any action or proceeding arising out of or relating to any Loan
Document, and the Borrower hereby irrevocably agrees that all claims in
  37

U.S.$                                       Dated:           , 19  


  FOR VALUE RECEIVED, the undersigned, HC 1995 ACQUISITION, INC., a     
corporation (the "Borrower"), HEREBY PROMISES TO PAY to the order of          
                (the "Lender") for the account of its Applicable Lending
Office (as defined in the Credit Agreement referred to below) the principal
sum of U.S.$[amount of the Lender's Commitment in figures] or, if less, the
aggregate principal amount of the Advances (as defined below) made by the
Lender to the Borrower pursuant to the Credit Agreement outstanding on the
Termination Date (as defined in the Credit Agreement).

  The Borrower promises to pay interest on the unpaid principal amount of
each Advance from the date of such Advance until such principal amount is
paid in full, at such interest rates, and payable at such times, as are
specified in the Credit Agreement.

  Both principal and interest are payable in lawful money of the United
States of America to Citibank, N.A., as Agent, at 399 Park Avenue, New York,
New York 10043, Attention:  Utilities Department, in same day funds.  Each
Advance made by the Lender to the Borrower pursuant to the Credit Agreement,
and all payments made on account of principal thereof, shall be recorded by
the Lender and, prior to any transfer hereof, endorsed on the grid attached
hereto which is part of this Promissory Note, provided that the failure to so
record any Advance or any payment thereof shall not affect the payment
obligations of the Borrower hereunder or under the Credit Agreement.

  This Promissory Note is one of the Notes referred to in, and is entitled
to the benefits of, the Credit Agreement, dated as of July 18, 1995 (as
amended, modified or supplemented from time to time, the "Credit Agreement"),
among the Borrower, the Lender and certain other lenders parties thereto, and
Citibank, N.A., as Agent for the Lender and such other lenders.  The Credit
Agreement, among other things, (i) provides for the making of advances (the
"Advances") by the Lender to the Borrower from time to time in an aggregate
amount not to exceed at any time outstanding the U.S. dollar amount first
above mentioned, the indebtedness of the Borrower resulting from each such
Advance being evidenced by this Promissory Note, and (ii) contains provisions
for acceleration of the maturity hereof upon the happening of certain stated
events and also for prepayments on account of principal hereof prior to the
maturity hereof upon the terms and conditions therein specified.

  The Borrower hereby waives presentment, demand, protest and notice of any
kind.  No failure to exercise, and no delay in exercising, any rights
hereunder on the part of the holder hereof shall operate as a waiver of such
rights.

  This Promissory Note shall be governed by, and construed in accordance
with, the laws of the State of New York.

(whether from the Borrower, the Agent or otherwise) in the same funds in

  3.   The Assignor (i) 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; (ii) makes no representation

the Assignor 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 the Loan Documents;
(iii) appoints and authorizes the Agent to take such action as agent on its
behalf and to exercise such powers under the Loan Documents as are delegated
to the Agent by the terms thereof, together with such powers as are
reasonably incidental thereto; (iv) agrees that it will perform in accordance
with their terms all of the obligations which by the terms of the Credit
Agreement are required to be performed by it as a Lender; [and] (v) specifies
as its Domestic Lending Office (and address for notices) and Eurodollar

respect of the interest assigned hereby (including, without limitation, all
payments of principal, interest and commitment fees with respect thereto) to

adjustments in payments under the Credit Agreement and the Notes for periods
prior to the Effective Date directly between themselves.

counterparts and by different parties in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute but one and the same instrument.

To each of the Lenders parties to the
  Credit Agreement referred to below,
  and to Citibank, N.A., as Agent


  Re:  WICOR, Inc.

Ladies and Gentlemen:

  This opinion is furnished to you pursuant to Section 3.01(a)(viii) of the
Credit Agreement, dated as of July 18, 1995 (the "Credit Agreement"), among
HC 1995 Acquisition, Inc. (the "Borrower"), the Banks parties thereto and the
other Lenders from time to time parties thereto, and Citibank, N.A., as
Agent.  Terms defined in the Credit Agreement and not otherwise defined
herein are used herein as therein defined.

  I am the senior legal advisor of the Guarantor and the Borrower and have
acted in that capacity in connection with the preparation, execution and
delivery of, and the Closing on this date under, the Credit Agreement.

  In that connection, I have examined:

  (a)  The Credit Agreement;

  (b)  The Guaranty;

  (c)  The other documents furnished by the Borrower and the Guarantor
       pursuant to Section 3.01 of the Credit Agreement;

  (d)  The Articles of Incorporation of the Borrower and all amendments
       thereto (the "Borrower Charter");

  (e)  The by-laws of the Borrower and all amendments thereto (the
       "Borrower By-laws");

  (f)  The Articles of Incorporation of the Guarantor and all amendments
       thereto (the "Guarantor Charter");

  (g)  The by-laws of the Guarantor and all amendments thereto (the
       "Guarantor By-laws");

  (h)  A certificate of the Secretary of State of the State of Delaware,
       dated July    , 1995, attesting to the continued corporate existence
       and good standing of the Borrower in that State; and

  (i)  A certificate of the Secretary of State of the State of Wisconsin,
       dated July     , 1995, attesting to the continued corporate
       existence and good standing of the Guarantor in that State.

I have also examined the originals, or copies certified to my satisfaction,
of such other corporate records of the Loan Parties, certificates of public
officials and of officers of the Loan Parties, and agreements, instruments
and other documents, as I have deemed necessary as a basis for the opinions
expressed below.  I have assumed the due execution and delivery, pursuant to
due authorization, of the Credit Agreement by the Banks and the Agent.  I
have witnessed the execution of counterparts of the Credit Agreement by the
Borrower and of the Guaranty by the Guarantor.
  47

  I am qualified to practice law in the State of Wisconsin and I do not
purport to be expert on any laws other than the laws of the State of
Wisconsin, the Federal laws of the United States and the General Corporation
Law of the State of Delaware.

  Based upon the foregoing and upon such investigation as I have deemed
necessary, I am of the following opinion:

  1.   The Borrower is a corporation duly organized, validly existing and
  in good standing under the laws of the State of Delaware.  The Guarantor
  is a corporation duly organized, validly existing and in good standing
  under the laws of the State of Wisconsin.  Each other Subsidiary of the
  Guarantor is duly incorporated, validly existing and in good standing
  under the laws of the jurisdiction of its incorporation.  Each Loan Party
  and each of their respective Subsidiaries has all requisite corporate
  powers and authority to own or lease and operate its properties and to
  carry on its business as now conducted and as proposed to be conducted.

  2.   The execution, delivery and performance by the Borrower of the
  Credit Agreement and the Notes are within the Borrower's corporate powers,
  have been duly authorized by all necessary corporate action, do not
  contravene (i) the Borrower Charter or the Borrower By-laws or (ii) any
  law, rule or regulation applicable to the Borrower or (iii) any
  contractual or legal restriction binding on or affecting the Borrower, and
  will not result in or require the creation or imposition of any lien or
  encumbrance on, or security interest in, any property (including, without
  limitation, accounts or contract rights) of the Borrower.  The Credit
  Agreement and the Notes have been duly executed and delivered on behalf of
  the Borrower. 

  3.   The execution, delivery and performance by the Guarantor of the
  Guaranty and the Fee Letter are within the Guarantor s corporate powers,
  have been duly authorized by all necessary corporate action, do not
  contravene (i) the Guarantor Charter or the Guarantor By-laws or (ii) any
  law, rule or regulation applicable to the Guarantor or (iii) any
  contractual or legal restriction binding on or affecting the Guarantor,
  and will not result in or require the imposition of any lien or
  encumbrance on, or security interest in, any property (including, without
  limitation, accounts or contract rights) of the Guarantor.  The Guaranty
  and the Fee Letter have been duly executed and delivered on behalf of the
  Guarantor.

  4.   No authorization, approval or other action by, and no notice to or
  filing with, any governmental authority or regulatory body, including,
  without limitation, the Public Service Commission of Wisconsin, is
  required for the due execution, delivery and performance by any Loan Party
  of any Loan Document to which it is a party or by the Guarantor of the Fee
  Letter.

  5.   There are no pending or, to the best of my knowledge, overtly
  threatened actions or proceedings against the Borrower or the Guarantor or
  any of its Subsidiaries before any court, governmental agency or
  arbitrator which purport to affect the legality, validity, binding effect
  or enforceability of any Loan Document or which are likely to have a
  materially adverse effect upon the condition, results of operations,
  operations or prospects of the Guarantor or any of its Subsidiaries, or
  upon the ability of any Loan Party to perform its obligations under any
  Loan Document to which such Loan Party is a party.

  6.   Neither the Guarantor nor any of its Subsidiaries is an "investment
  company" or a company "controlled" by an "investment company", within the
    meaning of the Investment Company Act of 1940, as amended.
  48

  7.   The Borrower is not a "holding company" within the meaning of the
  Public Utility Holding Company Act of 1935, as amended ("PUHCA").  The
  Guarantor is a "holding company" exempt from registration under Section 5
  of  PUHCA, pursuant to Section 3(a)(1) thereof.
  8.   
  Upon the merger of Hypro with and into the Borrower pursuant to the
  Agreement and Plan of Merger, dated as of July 13, 1995, among Hypro, the
  shareholders of Hypro named therein, the Borrower and the Guarantor, Hypro
  will be the surviving corporation and will assume all rights and
  obligations of the
   Borrower under the Credit Agreement and the Notes.

  The opinions set forth above are subject to the qualification that I
express no opinion as to the effect of the law of any jurisdiction other than
the State of Wisconsin, the federal laws of the United States of America and
the General Corporation Law of the State of Delaware.

  I am aware that Foley & Lardner and King & Spalding will rely upon the
opinions set forth in paragraphs 1 through 4 of this opinion in rendering
their opinions furnished pursuant to Sections 3.01(a)(viii) and 3.01(a)(ix),
respectively, of the Credit Agreement.

                Very truly yours,

                             FORM OF            OPINION OF SPECIAL WISCONSIN
COUNSEL         TO THE BORROWER AND THE GUARANTOR


                                                [Date of Closing]




To each of the Lenders parties to the
  Credit Agreement referred to below,
  and to Citibank, N.A., as Agent


       Re:  WICOR, Inc.

Ladies and Gentlemen:

  This opinion is furnished to you pursuant to Section 3.01(a)(viii) of the
Credit Agreement, dated as of July 18, 1995 (the "Credit Agreement"), among
HC 1995 Acquisition, Inc. (the "Borrower"), the Banks parties thereto and the
other Lenders from time to time parties thereto and Citibank, N.A., as Agent. 
Terms defined in the Credit Agreement and not otherwise defined herein are
used herein as therein defined.

  We have acted as special Wisconsin counsel to the Borrower and the
Guarantor in connection with the preparation, execution and delivery of, and
the Closing on this date under, the Credit Agreement.

  In that connection, we have examined the Credit Agreement and the
documents furnished by the Borrower and the Guarantor pursuant to Section
3.01 of the Credit Agreement.  We have also examined the originals, or copies
certified to our satisfaction, of such other corporate records of the Loan
Parties, and certificates of public officials and of officers of the Loan
Parties, and agreements, instruments and other documents, as we have deemed
necessary as a basis for the opinions expressed below.  As to questions of
fact material to such opinions, we have, when relevant facts were not
independently established by us, relied upon certificates of the Loan Parties
or their respective officers or of public officials.  We have assumed the due
execution and delivery, pursuant to due authorization, of the Credit
Agreement by the Banks and the Agent.  In addition, we have assumed (i) the
genuineness of the signatures of persons signing all documents in connection
with which this opinion is being rendered on behalf of parties thereto, (ii)
the authenticity of all documents submitted to us as originals or execution
copies, and (iii) the conformity to authentic original documents of all
documents submitted to us as certified, conformed or photostatic copies.

  With certain exceptions we are members of the Bar of the State of
Wisconsin only and do not hold ourselves out as experts on the law of any
other state or of any foreign country.  Therefore, this opinion does not
relate to the laws of any jurisdiction other than the State of Wisconsin and
the federal laws of the United States of America.

  With your consent, we have assumed the accuracy of the opinions set forth
in paragraphs 1 through 4 of the opinion letter of Robert A. Nuernberg, the
senior legal advisor of the Borrower and the Guarantor, delivered to you in
connection herewith, without having made any independent investigation
thereof, and we believe that both you and we are justified in so relying
thereon.
  50
  Based upon the foregoing and upon such investigation as we have deemed
necessary, we are of the following opinion:


  1.  Although there is no controlling precedent on point, assuming that (i)
the State of New York has a substantial relationship to the parties to the
Loan Documents, (ii) there is a reasonable basis for the parties' choice of
New York law, and (iii) the application of New York law would not be contrary
to important public policies of a state whose law would be applicable if the
parties' choice of law provision were disregarded (See Bush v. National
School Studios, Inc., 139 Wis. 2d 635, 642, 407 N.W. 2d 883, 886 (1987)), the
courts of Wisconsin will enforce the provisions of each Loan Document stating
that such Loan Document shall be governed by and construed in accordance with
the laws of the State of New York, except that, under federal law, the rates
of interest charged by any Lender that is a national bank located in a state
other than New York will be governed by the usury laws of such other state.

  2.  To the extent that Wisconsin usury laws are deemed to be controlling,
neither the Credit Agreement nor the Notes violate the applicable usury
limitations of Wisconsin law.

  3.  If a court were to hold that the Loan Documents are governed by, and
to be construed in accordance with, the laws of the State of Wisconsin, the
Loan Documents would be, under the laws of the State of Wisconsin, legal,
valid and binding obligations of each Loan Party party thereto and, subject
to the qualifications stated in the next paragraph hereof, enforceable
against each such Loan Party in accordance with their respective terms.

  The opinion set forth in paragraph 3 above is subject to the following
qualifications:

  (a)  The enforceability of each Loan Party s obligations under each Loan
       Document to which such Loan Party is a party is subject to the
       effect of any applicable bankruptcy, insolvency, reorganization,
       moratorium or similar law affecting creditors' rights generally.

  (b)  The enforceability of each Loan Party s obligations under each Loan
       Document to which such Loan Party is a party is subject to the
       effect of general principles of equity, including (without
       limitation) concepts of materiality, reasonableness, good faith and
       fair dealing (regardless of whether considered in a proceeding in
       equity or at law).

  (c)  Certain provisions of the Credit Agreement are or may be
       unenforceable in whole or in part under applicable law, but the
       inclusion of such provisions does not affect the validity of the
       Credit Agreement, and the Credit Agreement contains legally adequate
       provisions for the realization of the principal legal rights and
       benefits afforded by it.

  We hereby authorize King & Spalding to rely upon this opinion in rendering
their opinion under Section 3.01(a)(ix) of the Credit Agreement.

                Very truly yours,

                             OPINION                OF SPECIAL NEW YORK
COUNSEL                    TO THE AGENT



                                                  [Date of Closing]



Citibank, N.A., as Agent
   under the Credit Agreement
   referred to below and the
   Lenders from time to time
   parties thereto


  Re:  Wicor, Inc.

Ladies and Gentlemen:

  We have acted as special New York counsel to Citibank, N.A., individually
and as agent (the "Agent"), in connetion with the Credit Agreement, dated as
of July 18, 1995 (the "Credit Agreement"), among HC 1995 Acquisition, Inc.
(the "Borrower"), the Banks parties thereto and the other Lenders from time
to time parties thereto and the Agent.  Terms defined in the Credit Agreement
and not otherwise defined herein are used herein as therein defined.  This
opinion is being delivered to you in connection with Section 3.01(a) (ix) of
the Credit Agreement.

  In this connection, we have examined executed counterparts of the
following documents:

  (a)  The Credit Agreement;

  (b)  The Guaranty; and

  (c)  The Notes.

In our examination of the documents referred to above, we have assumed the
authenticity of all such documents submitted to us as originals, the
genuineness of all signatures, the due authority of the parties executing
such documents and the conformity to the originals of all such documents
submitted to us as copies.  We have also assumed that you have independently
evaluated, and are satisfied with, the creditworthiness of the Loan Parties
and the business terms of the Loan Documents.  We have relied, as to factual
matters, on the documents we have examined.

  To the extent that our opinions expressed below involve conclusions as to
matters governed by law other than the law of the State of New York, we have
relied upon the opinions of the Senior Legal Advisor to the Borrower and the
Guarantor and of Foley & Lardner, special Wisconsin counsel to the Loan
Parties, delivered on this date pursuant to Section 3.01(a)(viii) of the
Credit Agreement, and have assumed without independent investigation the
correctness of the matters set forth therein, our opinions expressed below
being subject to the assumptions, qualifications and limitations set forth in
such opinions.

  Based upon and subject to the foregoing, and subject to the qualifications
set forth below, we are of the opinion that the Credit Agreement, the
Guaranty and the Notes are the legal, valid and binding obligations of each
Loan Party party thereto enforceable against each such Loan Party in
accordance with their respective terms.

  Our opinion is subject to the following qualifications:
  52      
  (a)  The enforceability of each Loan Party s obligations under the Credit
Agreement, the Guaranty and the Notes is subject to the effect of any
applicable bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium or similar law affecting creditors' rights generally.

  (b)  The enforceability of each Loan Party s obligations under the Credit
Agreement, the Guaranty and the Notes is subject to the effect of general
principles of equity, including (without limitation) concepts of materiality,
reasonableness, good faith and fair dealing (regardless of whether considered
in a proceeding in equity or at law).  Such principles of equity are of
general application, and, in applying such principles, a court, among other
things, might not allow a contracting party to exercise remedies in respect
of a default deemed immaterial, or might decline to order an obligor to
perform covenants.

  (c)  We note further that, in addition to the application of equitable
principles described above, courts have imposed an obligation on contracting
parties to act reasonably and in good faith in the exercise of their
contractual rights and remedies, and may also apply public policy
considerations in limiting the right of parties seeking to obtain
indemnification under circumstances where the conduct of such parties is
determined to have constituted negligence.

  (d)  We express no opinion herein as to (i) Section 8.05 of the Credit
Agreement or Section 11 of the Guaranty, (ii) the enforceability of
provisions purporting to grant to a party conclusive rights of determination,
(iii) the availability of specific performance or other equitable remedies,
(iv) the enforceability of rights to indemnity under federal or state
securities laws or (v) the enforceability of waivers by parties of their
respective rights and remedies under law.

  (e)  Our opinions expressed above are limited to the law of the State of
New York, and we do not express any opinion herein concerning any other law.

  The foregoing opinion is solely for your benefit and may not be relied
upon by any other person or entity.


                         Very truly yours,
