($78,000.00) each payable on the last Business Day of January of
each year commencing January 31, 1997;  and, a final payment in the
amount of the outstanding principal balance of the ESOP Loan on
August 31, 2001.  Any amounts paid or prepaid with respect to the
ESOP Loan may not be reborrowed.

          2.2  ESOP Note.  The ESOP Loan made by the Bank pursuant
hereto shall be evidenced by the ESOP Note payable to the order of
the Bank in the original principal amount of Five Million Eleven
Thousand Two Hundred Forty-Eight Dollars ($5,011,248.00).  The Bank
is hereby authorized to record the date and amount of each payment
of principal and/or interest made under the ESOP Note, either on
the schedule annexed to and constituting a part of the ESOP Note
or otherwise on the Bank's books and records and any such
recordation shall constitute PRIMA FACIE evidence of the accuracy
of the information so recorded.  The ESOP Note shall (a) be dated
the Effective Date, (b) be stated to mature on August 31, 2001 and
be payable as provided in subsection 2.1 hereof, and (c) bear
interest for the period from and including the Effective Date until
the ESOP Note is paid in full on the unpaid principal amount
thereof from time to time outstanding at the applicable interest
rate per annum determined as provided in subsection 2.4.  Interest
on the ESOP Note shall be payable as specified in subsection 2.4.

          2.3  Voluntary Prepayments.  The Trust shall have the
privilege of prepaying the ESOP Loan in whole or in part at any
time upon prior notice to the Bank by paying to the Bank the
principal amount to be prepaid and accrued interest thereon to the
date of prepayment and any amounts due the Bank under Section 2.7
hereof.  Unless the Trust otherwise directs, principal payments
shall be first applied to the Prime Rate Portion until payment in
full thereof, with any balance applied to the Fixed Rate Portions
in the order in which their Interest Periods expire.

          2.4  Interest Rate Options.  (a)  Subject to all of the
terms and conditions of this Section, portions of the principal
indebtedness evidenced by the ESOP Note (all of the indebtedness
evidenced by the ESOP Note bearing interest at the same rate for
the same period of time being hereinafter referred to as a
"Portion") may, at the option of the Trust, bear interest with
reference to the ABN AMRO Rate or with reference to an Adjusted
Eurodollar Rate or with reference to an Adjusted CD Rate.  Portions
may be converted from time to time from one basis to another.  All
  12
of the indebtedness evidenced by the ESOP Note which is not part
of a Fixed Rate Portion shall constitute a single Prime Rate
Portion.  Anything contained herein to the contrary
notwithstanding, the obligation of the Bank to create, continue or
effect by conversion any Fixed Rate Portion shall be conditioned
upon the fact that at the time no Default or Event of Default shall
have occurred and be continuing.  The Trust hereby promises to pay
interest on each Portion at the rates and times specified in this
Section 2.4.


               (b)  Prime Rate Portion.  The Prime Rate Portion
     shall bear interest at the rate per annum equal to the ABN
     AMRO Rate as in effect from time to time, provided that if
     the Prime Rate Portion or any part thereof is not paid when
     due (whether by lapse of time, acceleration or otherwise)
     such Portion shall bear interest, whether before or after
     judgment, until payment in full thereof at the rate per annum
     determined by adding 2% to the interest rate which would
     otherwise be applicable thereto from time to time.  Interest
     on the Prime Rate Portion shall be payable quarterly in
     arrears on the last Business Day of each February, May,
     August and November in each year (commencing May 31, 1996)
     and at maturity of the ESOP Note and interest after maturity
     (whether by lapse of time, acceleration or otherwise) shall
     be due and payable upon demand.  

               (c)  Eurodollar Portions.  Each Eurodollar Portion
     shall bear interest for each Interest Period selected
     therefor at a rate per annum equal to the Adjusted Eurodollar
     Rate for such Interest Period, provided that if any
     Eurodollar Portion is not paid when due (whether by lapse of
     time, acceleration or otherwise) such Portion shall bear
     interest, whether before or after judgment, until payment in
     full thereof through the end of the Interest Period then
     applicable thereto at the rate per annum determined by adding
     2% to the interest rate which would otherwise be applicable
     thereto, and effective at the end of such Interest Period
     such Eurodollar Portion shall automatically be converted into
     and added to the Prime Rate Portion and shall thereafter bear
     interest at the interest rate applicable to the Prime Rate
     Portion after default.  Interest on each Eurodollar Portion
     shall be due and payable on the last day of each Interest
     Period applicable thereto and, with respect to any Interest
     Period applicable to an Eurodollar Portion in excess of 3
     months, on the date occurring every 3 months after the date
     such Interest Period began and at the end of such Interest
     Period, and interest after maturity (whether by lapse of
          time, acceleration or otherwise) shall be due and payable
  13
upon demand.  The Trust, or its designee appointed pursuant to
subsection (f) below, shall notify the Bank on or before 11:00 a.m. 
(Chicago time) on the third Business Day preceding the end of an
Interest Period applicable to an Eurodollar Portion whether such
Eurodollar Portion is to continue as an Eurodollar Portion, in
which event the Trust, or its designee appointed pursuant to
subsection (f) below, shall notify the Bank of the new Interest
Period selected therefor, and in the event the Trust or its
designee shall fail to so notify the Bank, such Eurodollar Portion
shall automatically be converted into and added to the Prime Rate
Portion as of and on the last day of such Interest Period.

               (d)  CD Portions.  Each CD Portion shall bear
     interest for each Interest Period selected therefor at a rate
     per annum equal to the Adjusted CD Rate for such Interest
     Period, provided that if any CD Portion is not paid when due
     (whether by lapse of time, acceleration or otherwise) such
     Portion shall bear interest, whether before or after
     judgment, until payment in full thereof through the end of
     the Interest Period then applicable thereto at the rate per
     annum determined by adding 2% to the interest rate which
     would otherwise be applicable thereto, and effective at the
     end of such Interest Period such CD Portion shall
     automatically be converted into and added to the Prime Rate
     Portion and shall thereafter bear interest at the interest
     rate applicable to the Prime Rate Portion after default. 
     Interest on each CD Portion shall be due and payable on the
     last day of each Interest Period applicable thereto and, with
     respect to any Interest Period applicable to a CD Portion in
     excess of 90 days, on the date occurring every 90 days after
     the date such Interest Period began and at the end of such
     Interest Period , and interest after maturity (whether by
     lapse of time, acceleration or otherwise) shall be due and
     payable upon demand.  The Trust, or its designee appointed
     pursuant to subsection (f) below, shall notify the Bank on or
     before 11:00 a.m. (Chicago time) on the Business Day
     preceding the end of an Interest Period applicable to a  CD
     Portion whether such CD Portion is to continue as a CD
     Portion, in which event the Trust, or its designee appointed
     pursuant to subsection (f) below, shall notify the Bank of
     the new Interest Period selected therefor, and in the event
     the Trust or its designee shall fail to so notify the Bank,
     such CD Portion shall automatically be converted into and
     added to the Prime Rate Portion as of and on the last day of
     such Interest Period. 

               (e)  Minimum Amounts.  Each Fixed Rate Portion
     shall be in a minimum amount  of Ten Thousand Dollars
          ($10,000.00).
   14

               (f)  Manner of Rate Selection.  The Trust shall
     notify the Bank by (i) 11:00 a.m. (Chicago time) at least
     three (3) Business Days prior to the date upon which the
     Trust requests that any Eurodollar Portion be created or that
     any part of the Prime Rate Portion or any part of a CD
     Portion be converted into an Eurodollar portion and (ii)
     11:00 a.m. (Chicago time) at least one (1) Business Day prior
     to the date upon which the Trust requests that any CD Portion
     be created or that any part of the Prime Rate Portion or any
     part of an Eurodollar Portion be converted into a CD Portion
     (each such notice to specify in each instance the amount
     thereof and the Interest Period selected therefor).  If any
     request is made to convert a Fixed Rate Portion into another
     type of Portion available hereunder, such conversion shall
     only be made so as to become effective as of the last day of
     the Interest Period applicable thereto.  All requests for the
     creation, continuance and conversion of Portions under this
     Agreement shall be irrevocable.  Such requests may be written
     or oral and the Bank is hereby authorized to honor telephonic
     requests for creations, continuances and conversions received
     by it from any person the Bank in good faith believes to be
     an authorized representative of the Trust without the need of
     independent investigation.  Until the Trust provides the Bank
     with written notice to the contrary and the Bank has had a
     reasonable opportunity to act thereon, the Trust hereby
     authorizes Wisconsin Gas Company to communicate to the Bank
     the interest rate selections to be made from time to time
     under this Agreement, and the Trust authorizes the Bank to
     honor all directions of Wisconsin Gas Company or any other
     person designated pursuant to this sentence in connection
     with the selection of interest rates under this Agreement
     until such time as the Bank receives contrary written notice
     and has had a reasonable opportunity to act thereon.  Until
     the Bank receives written notice from the Trust to the
     contrary, it shall be entitled to assume the foregoing power
     continues in full force and effect.


          2.5. Change of Law.  Notwithstanding any other provisions
of this Agreement or the ESOP Note, if at any time the Bank shall
determine in good faith that any change in applicable laws,
treaties or regulations or in the interpretation thereof makes it
unlawful for the Bank to create or continue to maintain any Fixed
Rate Portion, it shall promptly so notify the Trust and the
obligation of the Bank to create, continue or maintain any such
Fixed Rate Portion under this Agreement shall terminate until it
is no longer unlawful for the Bank to create, continue or maintain
such Fixed Rate Portion.  The Trust, on demand, shall, if the
  15
continued maintenance of any such Fixed Rate Portion is unlawful,
thereupon prepay the outstanding principal amount of the affected
Fixed Rate Portion, together with all interest accrued thereon and
all other amounts payable to the Bank with respect thereto under
this Agreement; provided, however, that the Trust may elect to
convert the principal amount of the affected Portion into another
type of Portion available hereunder, subject to the terms and
conditions of this Agreement.

          2.6. Unavailability of Deposits or Inability to Ascertain
Adjusted Eurodollar Rate or Adjusted CD Rate.  Notwithstanding any
other provision of this Agreement or the ESOP Note, if prior to the
commencement of any Interest Period, the Bank shall determine in
good faith that deposits in the amount of any Eurodollar Portion
or CD Portion scheduled to be outstanding during such Interest
Period are not readily available to the Bank in the relevant market
or, by reason of circumstances affecting the relevant market,
adequate and reasonable means do not exist for ascertaining the
Adjusted Eurodollar Rate or Adjusted CD Rate, then the Bank shall
promptly give notice thereof to the Trust and the obligations of
the Bank to create, continue or effect by conversion any such Fixed
Rate Portion in such amount and for such Interest Period shall
terminate until deposits in such amount and for the Interest Period
selected by the Trust shall again be readily available in the
relevant market and adequate and reasonable means exist for
ascertaining the Adjusted Eurodollar Rate or Adjusted CD Rate, as
the case may be.

          2.7. Funding Indemnity.  In the event the Bank shall
incur any loss, cost or expense (including, without limitation, any
loss, cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired or contracted to
be acquired by the Bank to fund or maintain any Fixed Rate Portion
or the relending or reinvesting of such deposits or other funds or
amounts paid or prepaid to the Bank) as a result of:

               (i)  any payment of a Fixed Rate Portion on a date
          other than the last day of the then applicable Interest
          Period for any reason, whether before or after default,
          and whether or not such payment is required by any
          provisions of this Agreement; or

               (ii) any failure by the Trust to create, continue
          or effect by conversion a Fixed Rate Portion on the date
          specified in a notice given pursuant to this Agreement;

then upon the demand of the Bank, the Trust shall pay to the Bank
such amount as will reimburse the Bank for such loss, cost or
expense.  If the Bank requests such a reimbursement, it shall
  16
provide to the Trust a certificate setting forth the computation
of the loss, cost or expense giving rise to the request for
reimbursement in reasonable detail and such certificate shall be
conclusive if reasonably determined.

          2.8. Lending Branch.  The Bank may, at its option, elect
to make, fund or maintain Portions of the ESOP Loan hereunder at
such of its branches or offices as the Bank may from time to time
elect.  To the extent reasonably possible, the Bank shall designate
an alternate branch or funding office with respect to the Fixed
Rate Portions to reduce any liability of the Trust to the Bank
under Section 2.12 hereof or to avoid the unavailability of an
interest rate option under Section 2.6 hereof, so long as such
designation is not otherwise disadvantageous to the Bank.

          2.9. Discretion of Bank as to Manner of Funding. 
Notwithstanding any provision of this Agreement to the contrary,
the Bank shall be entitled to fund and maintain its funding of all
or any part of the ESOP Note in any manner it sees fit, it being
understood, however, that for the purposes of this Agreement all
determinations hereunder shall be made as if the Bank had actually
funded and maintained each Fixed Rate Portion during each Interest
Period applicable thereto through the purchase of deposits in the
relevant market in the amount of such Fixed Rate Portion, having
a maturity corresponding to such Interest Period, and bearing an
interest rate equal to the Eurodollar Rate or CD Rate, as the case
may be, for such Interest Period.

          2.10.     Computation of Interest Payments.  All interest
on the ESOP Loan shall be computed on the basis of a year of 360
days for the actual number of days elapsed, except that interest
on the ESOP Loan which bears interest at the ABN AMRO Rate shall
be computed on the basis of a year of 365 or 366 days, as the case
may be, for the actual number of days elapsed.  Any change in the
interest rate on the ESOP Note resulting from a change in the ABN
AMRO Rate, if applicable, shall be effective as of the opening of
business on the day on which such change in the ABN AMRO Rate shall
become effective.  If any payment to be made hereunder or on the
ESOP Note shall be stated to be due on a day which is not a
Business Day, such payment may be made on the next succeeding
Business Day and such extension of time shall be included in the
computation of interest on the ESOP Loan unless in the case of an
Eurodollar Portion such payment would fall into another calendar
month in which case such payment shall be made on the immediately
preceding Business Day.  All payments (including prepayments) by
the Trust on account of principal, interest and fees, shall be made
without set-off or counterclaim and without any withholding for any
present or future taxes, duties, levies or charges to the Bank in
lawful money of the United States of America and in immediately
  17
available funds by wire transfer of funds as follows (or by such
other means as the Bank informs the Trust by prior written notice):

     Bank Name:     ABN AMRO Bank N.V., New York, N.Y.
                    ABA #026009580
                    F/O ABN AMRO Bank N.V. - Chicago Branch
                    ACCT No. 651-0-010111-42

          2.11.     Additional Interest on Loan Bearing Adjusted
Eurodollar Rate.  The Trust shall pay to the Bank, so long as the
Bank shall be required under regulations of the Board to maintain
reserves with respect to Liabilities or assets consisting of or
including Eurocurrency Liabilities, additional interest on the
unpaid principal amount of the ESOP Loan in any Interest Period
during which the ESOP Loan bears interest at the Adjusted
Eurodollar Rate, at an interest rate per annum equal at all times
to the remainder obtained by subtracting (i) the Adjusted
Eurodollar Rate for such Interest Period from (ii) the rate
obtained by dividing such Adjusted Eurodollar Rate by a percentage
equal to 100% minus the Eurodollar Rate Reserve Percentage for such
Interest Period, payable on each date on which interest is payable
with respect to such Interest Period.  Such additional interest
shall be determined by the Bank and notice thereof shall be given
to the Trust and Wisconsin Gas (or such other Person designated as
the Trust's designee).  If requested by the Trust or Wisconsin Gas,
the Bank 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 Trust to pay
such additional interest.

          2.12.     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 cases where the ESOP
     Loan is bearing interest at the Adjusted CD Rate, included in
     the Adjusted CD Rate Reserve Percentage or, in cases where
     the ESOP Loan is bearing interest at the Adjusted Eurodollar
     Rate, 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
     the Bank of maintaining the ESOP Loan at the Adjusted CD Rate
     or the Adjusted Eurodollar Rate, then the Trust shall from
     time to time, upon demand by the Bank pay to the Bank
     additional amounts sufficient to compensate the Bank for such
          increased cost.  The Bank agrees to notify the Trust and
  18
Wisconsin Gas (or such other Person designated as the Trust's
designee) of any such increased costs as soon as reasonably
practicable after determining that such increased cost is
applicable hereunder.  A certificate as to the amount of such
increased cost, submitted to the Trust and Wisconsin Gas (or such
other Person designated as the Trust's designee) by the Bank, shall
be conclusive and binding for all purposes, absent manifest error. 
If requested by the Trust or Wisconsin Gas (or such other Person
designated as the Trust's designee), the Bank shall provide a brief
summary of the manner in which such increased cost 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 Trust to pay such increased cost.

               (b)  If the Bank 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 the Bank
     or any corporation controlling the Bank and that the amount
     of such capital is increased by or based upon the existence
     of the Bank's commitment to lend hereunder and other
     commitments of this type, then, upon demand by the Bank, the
     Trust shall immediately pay to the Bank, from time to time as
     specified by the Bank, additional amounts sufficient to
     compensate the Bank or such corporation in the light of such
     circumstances, to the extent that the Bank reasonably
     determines such increase in capital to be allocable to the
     existence of the Bank's commitment hereunder.  The Bank
     agrees to notify the Trust and Wisconsin Gas (or such other
     Person designated as the Trust's designee) of any such
     additional amount as soon as reasonably practicable after the
     Bank makes such determination.  A certificate as to such
     amounts submitted to the Trust and Wisconsin Gas by the Bank
     shall be conclusive and binding for all purposes, absent
     manifest error.  If requested by the Trust or Wisconsin Gas
     (or such other Person designated as the Trust's designee),
     the Bank 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 Trust to pay
     such additional amount.

               (c)  The provisions contained in this Section 2.12
     shall survive for a period of 90 days after the repayment of
     the ESOP Loan.

          2.13.     Purpose.  The proceeds of the ESOP Loan shall
  19
be used by the Trust exclusively to repay in full, on the Effective
Date, all remaining principal and interest outstanding under a
current loan from M&I Marshall & Ilsley Bank, Milwaukee, Wisconsin. 
The proceeds of such M&I Marshall & Ilsley Bank loan (entered into
on November 4, 1991) were used exclusively by the Trust to acquire
WICOR Stock pursuant to the Stock Purchase Agreement.

          The following representations and warranties are made to
the Bank:

          5.3. Negative Covenants.  Until the ESOP Note is paid in
full and all obligations of the Trust hereunder performed, the

permit the Trust to:

               (a)  Fundamental Changes.  (i) Amend the ESOP or

     terminate the ESOP.

               (b)  Other Agreements.  Enter into any agreement or

will promptly pay all out-of-pocket expenses, including, but not
limited to, all legal fees and expenses, incurred by the Bank in

     or any interest on, the ESOP Note when the same becomes due
     and payable; or

               (b)  Any representation or warranty made or deemed
     made by the Company or the Trust in the Loan Documents or any
     certificate, document, financial statement or other statement
     furnished at any time under or in connection with the Loan
     Documents, proves to have been incorrect in any material
     respect on or as of the date made; or

               (c)  The Company or the Trust shall fail to perform
     or observe any term, covenant or agreement contained in this

     observed if the failure to perform or observe such other

     Bank; or

               (d)  The Trust shall generally not pay its debts as
     such debts become due, or shall admit in writing its
     inability to pay its debts generally, or shall make a general
     assignment for the benefit of creditors; or any proceeding

     an order for relief or the appointment of a receiver,
     trustee, custodian or other similar official for it or for
     any substantial part of its property and, in the case of any
     such proceeding instituted against it (but not instituted by
     it), such proceeding shall remain undismissed or unstayed for
     a period of 45 days, any of the actions sought in such
     proceeding (including, without limitation, the entry of an
     order for relief against, or the appointment of a receiver,
     trustee, custodian or other similar official for, it or for
     any substantial part of its property) shall occur or the
     Trust shall consent to or acquiesce in any such proceeding;

     this Agreement or the ESOP Note shall become unenforceable,
     or the Trust or the Company or any court or governmental or
     regulatory body having jurisdiction over the Trust, shall so
     assert in writing; or

               (f)  If there shall occur any Default or Event of
     Default under or any breach or violation of, or if the
     Company shall fail to observe or perform any of the covenants
     to be observed or performed by it under, the Guaranty or any
     of the other Loan Documents, which Default, Event of Default,

declare the Bank's obligations hereunder terminated forthwith,
whereupon such obligations shall terminate, and/or (ii) by notice
of default to the Trust, declare the ESOP Loan and all amounts
owing hereunder to be due and payable forthwith, whereupon the same
shall become immediately due and payable.  Except as expressly
provided above in this subsection, presentment, demand, protest or
further notice of any kind are hereby expressly waived.  This

          7.3. No Waiver; Cumulative Remedies.  If the Bank fails
to exercise, or delays before exercising, any right, remedy, power

a waiver thereof.  The single or partial exercise of any right,

and the vesting of venue therein.

          7.7. Severability.  Any provision of this Agreement which

of such prohibition or unenforceability without invalidating the
remaining provisions hereof.

          7.8. Headings.  Section, subsection and paragraph
headings in this Agreement are included herein for convenience of
reference only and shall not constitute a part of this Agreement
for any other purpose.

          7.9. Special Limitations.

               (a)  Notwithstanding any other provision in this
     Agreement or the ESOP Note, the obligations of the Trust and
          the Company and the rights of the Bank under this Agreement
  28
and the ESOP Note are subject to and limited by any limitations as
to recourse against the Trust, transfer of ESOP assets required to
qualify the ESOP Loan for an exemption from any prohibition
relating to transactions with the ESOP by a Disqualified Person or
otherwise, under Section 4975 of the Code or Section 406 and 408
of ERISA, or any similar or successor provision of applicable law,
but only to the extent, and for so long as, such prohibitions would
be applicable to the Bank and the ESOP Loan hereunder.  The Trust
and the Company will, and will use reasonable efforts to cause the
ESOP and Wisconsin Gas to, comply with any reasonable request from
the Bank for assistance in establishing the inapplicability of such
a prohibition or the qualification for an exemption thereunder. 
No such limitation or impairment shall in any way impair, diminish
or delay the performance of, any obligations of the Company under
any of the Loan Documents, or, upon a Default or Event of Default,
limit or impair the right of the Bank to accelerate as against, and
collect from, the Company, the entire indebtedness under the ESOP
Loan pursuant to the terms of the Guaranty.

               (b)  The Bank, the Company and the Trust
     acknowledge and agree that the limitations referred to in
     subsection 7.9(a) require, among other things, that the
     rights, powers and remedies shall be limited by the following
     requirements to the extent and so long as the same would be
     applicable to the Bank and the ESOP Loan hereunder:

                    (i)  That payments of principal and interest
          (or any other sum due) with respect to the ESOP Loan
          shall be made by the Trust only from:  (A) cash
          contributions made to the Trust under the ESOP by
          Wisconsin Gas or any contributing employer to enable the
          Trust to make such payments; (B) from any earnings
          attributable to such contributions and any dividends
          paid on the shares of WICOR Stock; and (C)
          notwithstanding that the Trust has not granted to the
          Bank a security interest in the WICOR Stock, to the
          extent permitted by applicable law, the Bank shall have
          recourse against the WICOR Stock (other than those
          shares of WICOR Stock which have been allocated to
          accounts of ESOP participants) and any dividends paid on
          the shares of the WICOR Stock (other than those shares
          of WICOR Stock which have been allocated to accounts of
          ESOP participants) for the ESOP Loan and the Bank shall
          have no recourse against the Trust for the ESOP Loan,
          except to the extent of the WICOR Stock (other than
          those shares of WICOR Stock which have been allocated to
          accounts of ESOP participants) and such contributions,
                    earnings and dividends held by the Trust; and
  29
                    (ii) That upon the occurrence of an Event of
          Default, the value of Trust assets transferred in
          satisfaction of the ESOP Loan must not exceed the amount
          of default.

          7.10.     No Representation.  The Company, Wisconsin Gas
and the Trust have independently, and with legal counsel and other
advisors of their choice, made to their satisfaction such
investigations, evaluations and determinations with regard to such
qualification and related issues as the Company, Wisconsin Gas, the
Trust and their counsel and other advisors have deemed necessary
and have done so taking into consideration the terms of this
Agreement and any proposal or commitment of the Bank pursuant to
which this Agreement has been entered into.

          7.11.     Trustee's Exculpation.  This Agreement is
executed by the Trustee, not in its individual capacity, but solely
in its capacity as Trustee pursuant to the power and authority
conferred upon it under and by virtue of the terms and provisions
of the Trust Agreement, and the representations, warranties,
covenants, undertakings and agreements herein made and entered into
are made and entered into solely for the purpose of binding the
Trust.  It is expressly agreed by the Bank, and by all Persons
claiming by, through or under the Bank, that no personal liability
is assumed by or shall at any time arise or be asserted or enforced
against the Trustee, in its individual capacity, or against any
beneficiary under the Trust Agreement, or any of its or their
respective officers, partners, employees, agents, personal
representatives, heirs, executors, administrators, successors or
assigns, on account of this Agreement or on account of the
representations, warranties, covenants, undertakings and agreements
herein contained, either express or implied, all such liability,
if any, being expressly waived and released by the Bank, and by all
Persons claiming by, through or under the Bank, and that recourse
hereunder shall be limited exclusively to the Trust and the trust
assets referred to in Section 7.9(b) above.

          IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed and delivered by their respective
officers, thereunto duly authorized, as of the date first above
written.

conformity with the laws, rules of law, and regulations governing
loans to employee stock ownership trusts to purchase qualifying
