                                  DEFINITIONS

   1.1      Defined Terms.  As used in this Agreement, the following terms
shall have the following meanings (such meanings to be equally applicable to
both the singular and plural forms of the terms defined):

associates (as defined in Rule 12b-2 under the Exchange Act), becomes, by way
of any transaction not approved by resolution of a majority of Continuing
Directors of the Company or the applicable Parent of the Company, the
beneficial owner of the shares of the Company or such Parent having more than

directors of the Company or such Parent.

   "Adjusted CD Rate" means, for the Interest Period for each Adjusted CD
Rate Advance made by each Bank comprising part of the same Syndicated
Borrowing, an interest rate per annum equal to the sum of:  (a) the rate per
annum obtained by dividing (i) the rate of interest determined by the Company
to be the average (rounded upward to the nearest whole multiple of 1/100 of 1%
per annum, if such average is not such a multiple) of the consensus bid rate
determined by each of the Reference Banks for the bid rates per annum, at
10:00 a.m. (New York City time) (or as soon thereafter as practicable) on the
first day of such Interest Period, of two or more New York certificate of
deposit dealers of recognized standing selected by such Reference Bank for the
purchase at face value of certificates of deposit of such Reference Bank in an
amount approximately equal to the principal amount of such Reference Bank's
Adjusted CD Rate Advance comprising part of such Syndicated Borrowing during
such Interest Period and with a maturity approximately equal to such Interest
Period, by (ii) a percentage equal to 100% minus the Adjusted CD Rate Reserve
Percentage for such Interest Period, plus (b) the Assessment Rate for such
Interest Period.  The Adjusted CD Rate for the Interest Period for each
Adjusted CD Rate Advance comprising part of the same Syndicated Borrowing

each Adjusted CD Rate Advance comprising part of the same Syndicated
Borrowing, the percentage which is in effect on the first day of such Interest
Period under regulations issued from time to time by the Board of Governors of

reserve requirement (including, but not limited to, any emergency,
supplemental or other marginal reserve requirement) for a member bank of the
Federal Reserve System with deposits exceeding five billion dollars with
respect to liabilities consisting of or including (among other liabilities)
U.S. dollar non-personal time deposits of $100,000 or more in the United
States and with a maturity equal to such Interest Period.

    1.2  Computation of Time Periods.  In this Agreement, when computing
periods of time from a specified date to a later specified date, the word
"from" means "from and including" and the words "to" and "until" each means

    1.3  Accounting Terms and Principles.  All accounting terms used herein
shall be interpreted, all accounting determinations hereunder shall be made,
and all financial statements required to be delivered hereunder shall be
prepared, in accordance with generally accepted accounting principles as in
effect from time to time, applied on a basis consistent (except for changes
concurred in by the Company's independent accountants or, in the case of the
financial statements required to be delivered pursuant to Section 7.17(a), as
determined by the Company to be required in accordance with then existing
generally accepted accounting principles) with the December 31, 1991, audited
consolidated financial statements of the Company and its consolidated
Subsidiaries.  If any preparation of the financial statements referred to in
Section 7.17 hereafter occasioned by the promulgation of rules, regulations,
pronouncements, and opinions by or required by the Financial Accounting
Standards Board or the American Institute of Certified Public Accountants (or
successors thereto or agencies with similar functions) results in a change in
the method of calculation of financial covenants, standards, or terms found in
Articles I or VII hereof, the parties hereto agree to enter into good faith
negotiations in order to amend such provisions so as to equitably reflect such
changes with the desired result that the criteria for evaluating the Company's
financial condition shall be the same after such changes as if such changes
had not been made.  Specifically, the parties agree that the effect of any
change in Consolidated Tangible Net Worth or Consolidated Net Income arising
from the adoption by the Company of Financial Accounting Standard 106 and/or
109 shall be reflected as adjustments to the definitions of Consolidated
Tangible Net Worth and Consolidated Net Income, as appropriate, except to the
extent that such adjustments exceed $100,000,000, and that the determination
by the Company of the amount of these adjustments, as communicated in writing
by the Company to the Banks, shall be binding, absent manifest error.

    1.4  Specified Subsidiaries.  The Company may from time to time designate
as many as 10 Subsidiaries as Specified Subsidiaries.  Such designated
Specified Subsidiaries, if approved by the Banks in accordance with the
provisions of this Section 1.4 and upon the satisfaction of the conditions to
borrowing set forth in Sections 5.3 and 5.4 hereof, may borrow directly from
the Banks under the terms of this Agreement on the same basis and under the
same conditions as the Company.

    (a) The designation of a Specified Subsidiary shall be made by written
notice from the Company to each Bank designating the proposed Subsidiary, the
maximum aggregate amount of Permitted Advances to be made available to the
proposed Subsidiary at any one time and the effective date of the designation,
which shall be at least 30 days after the date of the written notice.  The
written notice shall be accompanied by copies of the financial statements
required by Section 5.4(j) hereof.  The designated Subsidiary shall become a
Specified Subsidiary on the later of (i) the effective date specified in such
written notice, or (ii) the date upon which all of the documents and
instruments required pursuant to Section 5.4 with respect to such Subsidiary
have been delivered to the Banks, in either event so long as, within 30 days
after the date of the written notice, the Majority Banks have notified the
Company in writing that they approve of the designation.  Failure on the part
of any Bank to respond to any such request shall be deemed to be a denial of
such request.  If the Majority Banks agree in writing to the designation, such
designation shall be binding upon all Banks.

    (b) The Company may propose by written notice an increase in the maximum
amount of Permitted Advances for a Specified Subsidiary effective as of a date
at least 30 days after the date of such written notice, which written notice
shall be accompanied by the most recent (i) annual unaudited financial
statements, and (ii) unaudited interim financial statements with respect to
such Specified Subsidiary as of the date of such written notice, in each case
certified as complete and correct by an authorized financial officer of the
Specified Subsidiary.  The increase shall be effective on the effective date
specified in the written notice so long as, within 30 days after the date of
the written notice, the Majority Banks have notified the Company in writing
that they approve of the increase.  Failure on the part of any Bank to respond
to any such proposed increase shall be deemed to be a denial of such proposed
increase.  If the Majority Banks agree in writing to such increase, such
agreement shall be binding upon all Banks.

    (c) All Specified Subsidiaries shall be Wholly-owned Subsidiaries.

    (d) The Company may discontinue the designation of any Subsidiary as a
Specified Subsidiary, or reduce the maximum amount of Permitted Advances for
any Specified Subsidiary, by written notice to the Banks at least 30 days
prior to the effective date of such discontinuance or reduction, provided that
no Subsidiary shall cease to be designated as a Specified Subsidiary at any
time during which any Permitted Advances to such Subsidiary are outstanding;
and provided further that the maximum amount of Permitted Advances available
to any Specified Subsidiary shall not be reduced to an amount less than its
Permitted Advances outstanding as of the date of such reduction.

    (e) The Company shall deliver or cause to be delivered to the Banks,
within 120 days after the close of the fiscal year of each Specified
Subsidiary, annual unaudited financial statements in the form required by
Section 5.4(j) hereof with respect to each such Specified Subsidiary,
certified as complete and correct by an authorized financial officer of the
applicable Specified Subsidiary.

    (f) The aggregate principal amount of (i) Permitted Advances to all
Specified Subsidiaries outstanding at any time shall not exceed $100,000,000;
and (ii) all Advances (including Permitted Advances) outstanding at any time
shall not exceed the aggregate Commitments of the Banks at such time.  

                                  ARTICLE II
                       THE SYNDICATED BORROWING FACILITY

    2.1 The Syndicated Borrowing Facility.  Each Bank severally agrees, on
the terms and conditions provided herein, to make Syndicated Advances to the
Company or a Specified Subsidiary, as applicable, from time to time on any
Business Day during the period from the date hereof to the Termination Date in
an aggregate amount not to exceed at any time outstanding the amount of such
Bank's Available Commitment (the "Syndicated Borrowing Facility").  Subject to
Section 4.11, each Syndicated Borrowing shall be in an aggregate amount not
less than $10,000,000 (and in integral multiples of $5,000,000 in excess
thereof), shall be made on the same day from the Banks ratably according to
their respective Commitments and shall consist of Syndicated Advances of the
same Type.  Within the limits of each Bank's Available Commitment, the Company
or a Specified Subsidiary, as applicable, may borrow under this Section 2.1,
repay pursuant to Section 4.8, or prepay pursuant to Section 4.6, and reborrow
under this Section 2.1.  The Syndicated Borrowing Facility is an entirely
separate facility from the Competitive Bid Borrowing Facility; the aggregate
principal amount of Syndicated Advances outstanding at any time, together with
the aggregate principal amount of Competitive Bid Advances outstanding at such
time, shall not exceed the aggregate Commitments of the Banks at such time.

    2.2  Making the Syndicated Advances.  Each Syndicated Borrowing shall be
made by telephonic notice (which shall be confirmed in writing not later than
two hours thereafter in the case of a Borrowing consisting of Eurodollar Rate
Advances or Adjusted CD Rate Advances, and not later than 30 minutes
thereafter in the case of a Borrowing consisting of Base Rate Advances),
telecopier notice or telex notice given by the Company or a Specified
Subsidiary, as applicable, to each Bank not later than (i) 10:00 a.m. (Chicago
time) three Business Days prior to the proposed Borrowing Date, in the case of
a Borrowing comprised of Eurodollar Rate Advances, (ii) 10:00 a.m. (Chicago
time) two Business Days prior to the proposed Borrowing Date, in the case of a
Borrowing comprised of Adjusted CD Rate Advances, or (iii) 9:00 a.m. (Chicago
time) on the proposed Borrowing Date, in the case of a Borrowing comprised of
Base Rate Advances.  Each notice of Syndicated Borrowing pursuant to this
Section 2.2 (a "Notice of Syndicated Borrowing") shall be in substantially the
form of Exhibit 2.2 hereto, specifying the proposed Borrowing Date, the Type
of Syndicated Advances, the aggregate amount of the proposed Syndicated
Borrowing, the Interest Period for each such Syndicated Advance, and for each
Bank such Bank's ratable portion of such Syndicated Borrowing.  With respect
to Advances to the Company, each Bank, for the account of its Applicable
Lending Office, shall before 2:00 p.m. (Chicago time) on the date of such
Syndicated Borrowing specified in the Notice of Syndicated Borrowing received
from the Company, pursuant to the preceding sentence, deposit such Bank's
ratable portion of such Syndicated Borrowing in immediately available funds to
the Company's account (number xx-xxxxx) at Continental Bank N.A. (unless
another account is designated by the Company to the Banks in writing for such
purpose).  With respect to Permitted Advances to a Specified Subsidiary, each
Bank, for the account of its Applicable Lending Office, shall before 2:00 p.m.
(Chicago time) on the date of such Syndicated Borrowing specified in the
Notice of Syndicated Borrowing received from such Specified Subsidiary,
deposit such Bank's ratable portion of such Syndicated Borrowing in
immediately available funds to the account designated by such Specified
Subsidiary to the Banks in writing for such purpose.

                                  ARTICLE III
                    THE COMPETITIVE BID BORROWING FACILITY

    3.1  The Competitive Bid Borrowing Facility.  Each Bank severally agrees,
on the terms and conditions provided herein, to make available to the Company
or a Specified Subsidiary, as applicable, a competitive bid borrowing facility
(the "Competitive Bid Borrowing Facility") pursuant to which the Company or a
Specified Subsidiary, as applicable, may, from time to time on any Business
Day during the period from the date hereof to the Termination Date and as
otherwise set forth in this Article III, request all of the Banks to offer to
make Competitive Bid Advances to the Company or a Specified Subsidiary, as
applicable; provided, however, that the Company or a Specified Subsidiary, as
applicable, shall be under no obligation to request any Bank to offer to make
Competitive Bid Advances if such Bank has provided prior written notice to the
Bid Advance Agent and the Company or a Specified Subsidiary, as applicable,
that it desires not to participate in the Competitive Bid Borrowing Facility
for a period of time which includes the date of the Company's or a Specified
Subsidiary's, as applicable, request.  Each Bank of which any such request
shall be made may, but shall have no obligation to, make such offers and the
Company or a Specified Subsidiary, as applicable, may, but shall have no
obligation to, accept any such offers in the manner set forth in this Article
III.  The Competitive Bid Borrowing Facility is an entirely separate facility
from the Syndicated Borrowing Facility; provided that the aggregate principal
amount of Competitive Bid Advances outstanding at any time, together with the
aggregate principal amount of Syndicated Advances outstanding at such time,
shall not exceed the aggregate Commitments of the Banks at such time.  Within
the limits and on the conditions set forth in this Article III, the Company or
a Specified Subsidiary, as applicable, may from time to time borrow, repay,
and reborrow under this Article III.

    3.2  Competitive Bid Quote Request.  When the Company or a Specified
Subsidiary, as applicable, wishes to request offers to make Competitive Bid
Advances under this Article III, it shall deliver to the Bid Advance Agent a
Competitive Bid Quote Request by telephone (confirmed immediately in writing),
telecopier, or telex so as to be received no later than 9:30 a.m. (Chicago
time) at least one Business Day prior to the Borrowing Date proposed therein
(or, upon reasonable prior notice to the Banks, such other time and date as
the Company or a Specified Subsidiary, as applicable, and the Majority Banks
(or, if the Bid Advance Agent is a Bank, the Bid Advance Agent) may agree),
specifying:  

    (a) the proposed Borrowing Date, which shall be a Business Day, for the
proposed Competitive Bid Advances;

    (b) the aggregate principal amount of such Competitive Bid Advances;

    (c) the Interest Period or Periods applicable thereto; and

    (d) if fewer than all Banks are to be solicited, the name of the Banks to
be solicited.

    The Company or a Specified Subsidiary, as applicable, may request offers
to make Competitive Bid Advances for more than one Interest Period, but not
more than six Interest Periods, in a single Competitive Bid Quote Request.  No
Competitive Bid Quote Request shall be given within five Business Days (or
such other number of days as the Company or a Specified Subsidiary, as
applicable, and the Majority Banks (or, if the Bid Advance Agent is a Bank,
the Bid Advance Agent) may agree) of any other Competitive Bid Quote Request. 
A Competitive Bid Quote Request that does not conform substantially to the
format of Exhibit 3.2 hereto shall be rejected, and the Bid Advance Agent
shall promptly notify the Company or a Specified Subsidiary, as applicable, of
such rejection by telephone, telex, or telecopy.

    3.3  Invitation for Competitive Bid Quotes.  Promptly upon receipt of a
Competitive Bid Quote Request that is not rejected pursuant to Section 3.2,
the Bid Advance Agent shall send to each of the Banks (or, if fewer than all
of the Banks shall have been specified by the Company or a Specified
Subsidiary, as applicable, therein pursuant to Section 3.1, to each of the
specified Banks) by telex or telecopy a copy of such Competitive Bid Quote
Request or a summary of the contents thereof.

    3.4  Submission and Contents of Competitive Bid Quotes. (a) Each Bank
receiving notice of a Competitive Bid Quote Request from the Bid Advance Agent
pursuant to Section 3.3 may, in its sole discretion, submit a Competitive Bid
Quote containing an offer or offers to make Competitive Bid Advances in
response to such Competitive Bid Quote Request.  Each Competitive Bid Quote
must comply with the requirements of this Section 3.4 and must be submitted to
the Bid Advance Agent by telex or telecopy at its offices specified in or
pursuant to Section 10.2 not later than 9:00 a.m. (Chicago time) on the
proposed Borrowing Date (or, upon reasonable prior notice to the Banks, such
other time and date as the Company or a Specified Subsidiary, as applicable,
and the Majority Banks (or, if the Bid Advance Agent is a Bank, the Bid
Advance Agent) may agree); provided, if the Bid Advance Agent is a Bank, that
Competitive Bid Quotes submitted by the Bid Advance Agent in its capacity as a
Bank may be submitted, and may only be submitted, if such Bid Advance Agent
notifies the Company or a Specified Subsidiary, as applicable, of the terms of
the offer or offers contained therein not later than 30 minutes prior to the
time the other Banks are required to submit their Competitive Bid Quotes on
the proposed Borrowing Date. Subject to Articles V and VIII, any Competitive
Bid Quote so made shall be irrevocable except with the written consent of the
Bid Advance Agent and the Company or a Specified Subsidiary, as applicable.

    (b)  Each Competitive Bid Quote shall be in substantially the form of
Exhibit 3.4 hereto and shall in any case specify:

       (i) the proposed Borrowing Date, which shall be the same as that set
    forth in the applicable Competitive Bid Quote Request;

       (ii) the principal amount of the Competitive Bid Advance for which
    each such offer is being made, which principal amount (1) may be greater
    than, less than, or equal to the Commitment of the quoting Bank, (2) must
    be at least $2,000,000 (and in integral multiples of $500,000 in excess
    thereof), and (3) may not exceed the aggregate principal amount of
    Competitive Bid Advances for which offers were requested;

       (iii) the Absolute Rate offered for each such Competitive Bid Advance
    and the Interest Period applicable thereto; and

       (iv) the identity of the quoting Bank.

    (c)  The Bid Advance Agent shall reject any Competitive Bid Quote that:

       (i) is not substantially in the form of Exhibit 3.4 hereto or does not
    specify all of the information required by Section 3.4(b);

       (ii) contains qualifying, conditional, or similar language, other than
    any such language contained in Exhibit 3.4; provided, however, that a
    quoting Bank may condition its Competitive Bid Quote on acceptance by the
    Company or a Specified Subsidiary, as applicable, of a specified minimum
    principal amount of such Bank's proposed Competitive Bid Advance;

       (iii) proposes terms other than or in addition to those set forth in
    the applicable Competitive Bid Quote Request; or

       (iv) arrives after the time set forth in Section 3.4(a).

If any Competitive Bid Quote shall be rejected pursuant to this Section
3.4(c), the Bid Advance Agent shall notify the relevant Bank of such rejection
as soon as practical.

    3.5  Notice to the Company or a Specified Subsidiary, as applicable.  The
Bid Advance Agent shall promptly, but in no event later than 9:30 a.m.
(Chicago time) on the proposed Borrowing Date (or such other time and date as
the Company or a Specified Subsidiary, as applicable, and the Majority Banks
(or, if the Bid Advance Agent is a Bank, the Bid Advance Agent) may agree),
notify the Company or a Specified Subsidiary, as applicable, of the terms (i)
of any Competitive Bid Quote submitted by a Bank that is in accordance with
Section 3.4 and (ii) of any Competitive Bid Quote submitted by a Bank which
amends, modifies, or is otherwise inconsistent with a previous Competitive Bid
Quote submitted by such Bank with respect to the same Competitive Bid Quote
Request.  Any such subsequent Competitive Bid Quote shall be disregarded by
the Bid Advance Agent unless such subsequent Competitive Bid Quote
specifically states that it is submitted solely to correct a manifest error in
such former Competitive Bid Quote.  The Bid Advance Agent's notice to the
Company or a Specified Subsidiary, as applicable, shall specify the aggregate
principal amount of Competitive Bid Advances for which offers have been
received for each Interest Period specified in the related Competitive Bid
Quote Request and the respective principal amounts and Absolute Rates so
offered.

    3.6  Acceptance and Notice by the Company or a Specified Subsidiary, as
applicable.  Not later than 10:00 a.m. (Chicago time) on the proposed
Borrowing Date (or, upon reasonable prior notice to the Banks, such other time
and date as the Company or a Specified Subsidiary, as applicable, and the
Majority Banks (or, if the Bid Advance Agent is a Bank, the Bid Advance Agent)
may agree), the Company or a Specified Subsidiary, as applicable, shall either
cancel the applicable Competitive Bid Quote Request by giving the Bid Advance
Agent notice to that effect, or notify the Bid Advance Agent of its acceptance
or non-acceptance of any or all of the offers so notified to it pursuant to
Section 3.5; provided, however, that the failure by the Company or a Specified
Subsidiary, as applicable, to give such notice of acceptance or non-acceptance
to the Bid Advance Agent with respect to any such offer shall be deemed to be
a rejection of such offer.  In the case of acceptance, such notice (a "Notice
of Competitive Bid Borrowing") shall be substantially in the form of Exhibit
3.6 hereto and shall specify the aggregate principal amount of offers for each
Interest Period that are accepted.  The Company or a Specified Subsidiary, as
applicable, may accept any Competitive Bid Quote in whole or in part; provided
that:  

    (a) the aggregate principal amount of Competitive Bid Advances may not
exceed, but may be less than, the applicable amount set forth in the related
Competitive Bid Quote Request;

    (b) acceptance of offers may only be made on the basis of ascending
Absolute Rates starting with the lowest and continuing with the next lowest
until offers in the aggregate amount specified by the Company or a Specified
Subsidiary, as applicable, for acceptance shall have been accepted; and

    (c) the Company or a Specified Subsidiary, as applicable, may not accept
any offer that is described in Section 3.4(c) or that otherwise fails to
comply with the requirements of this Agreement.

    3.7  Allocation by Bid Advance Agent.  If offers are made by two or more
Banks with the same Absolute Rates for a greater aggregate principal amount
than the amount in respect of which offers remain to be accepted, as specified
by the Company or a Specified Subsidiary, as applicable, for the related
Interest Period (after giving effect to the acceptance of all offers made at
lower rates), the principal amount of Competitive Bid Advances in respect of
which such offers are accepted shall be allocated by the Bid Advance Agent
among such Banks as nearly as possible (in such multiples, not greater than
$500,000, as the Bid Advance Agent may deem appropriate) in proportion to the
aggregate principal amount of such offers.  Allocations by the Bid Advance
Agent of the amounts of Competitive Bid Advances shall be conclusive in the
absence of manifest error.

    3.8  Notification of Acceptances to the Affected Banks.  Promptly
following its receipt of a Notice of Competitive Bid Borrowing, the Bid
Advance Agent shall notify by telex or telecopy each Bank that has made a
Competitive Bid Quote of the extent to which its offer or offers have been
accepted, specifying in such notice the principal amount of each Competitive
Bid Advance in respect of which such Competitive Bid Quote has been accepted,
the Interest Period therefor and the Absolute Rate therefor.

    3.9  Funding of Competitive Bid Advances.  Each Bank that is to make a
Competitive Bid Advance in connection with any Notice of Competitive Bid
Borrowing shall, before 12:00 noon (Chicago time) on the first day of the
Interest Period therefor specified in the notice from the Bid Advance Agent
delivered pursuant to Section 3.8, deposit the amount of each of such Bank's
Competitive Bid Advances in immediately available funds to the Company's
account (number xx-xxxxx) at Continental Bank N.A. (unless another account is
designated by the Company to the Banks in writing for such purpose) or, with
respect to Competitive Bid Advances to a Specified Subsidiary, to the account
designated by such Specified Subsidiary to the Banks in writing for such
purpose.  Promptly following each Competitive Bid Borrowing, the Company or a
Specified Subsidiary, as applicable, shall notify each Bank of the aggregate
amount of Competitive Bid Advances made in connection therewith, the
consequent Syndicated Reduction and the Interest Periods for such Competitive
Bid Advances.

                                  ARTICLE IV

from time to time.

    4.3  Interest Rate Determinations. (a) Each Reference Bank agrees to
furnish to the Company and to each Bank timely information for the purpose of
determining each Adjusted CD Rate or Eurodollar Rate, as applicable.  Subject
to subsection (c) of this Section, if any one or more of the Reference Banks
shall not furnish such timely information to the Company and the Banks for
determination of any such interest rate, the Company shall determine such
interest rate on the basis of timely information furnished by the remaining
Reference Banks.

    (b) The Company shall give prompt notice to the Banks of any applicable
interest rate determined by the Company for purposes of Section 4.1 and the
applicable rate, if any, furnished by each Reference Bank for determining the

    (c) If any Reference Bank shall fail to furnish timely information to the
Company and the Banks for determining the Adjusted CD Rate or the Eurodollar
Rate with respect to any requested Borrowing, the Company shall be entitled to
designate one or more of the other Banks hereunder as successor Reference
Banks.  Each such designation shall be subject to the consent of the Majority
Banks, which consent shall not be unreasonably withheld.  Upon receipt of such
consent, the affected Reference Bank shall cease to be a Reference Bank
hereunder and each successor Reference Bank shall be a Reference Bank for all
purposes of this Agreement until such time as either (i) such Reference Bank
shall no longer be a Bank hereunder or (ii) the Company shall replace such
Reference Bank pursuant to this Section 4.3(c).

ratably in part the respective Commitments of the Banks, provided that (i) any
such reduction shall not exceed an aggregate amount equal to the unused
portions of the respective Available Commitments of the Banks at such time,
and (ii) in the case of any partial reduction of the Commitments, such partial
reduction shall be in an aggregate amount not less than the lesser of (A)
$10,000,000 (or an integral multiple of $5,000,000 in excess thereof) and (B)
the aggregate amount at such time of the unused portions of the respective
Available Commitments.

     4.6  Optional Prepayments.  The Company or a Specified Subsidiary, as
applicable, may, upon irrevocable notice to the Banks, given not later than
9:00 a.m. (Chicago time) on the proposed date of prepayment, by telephone (to
be confirmed immediately in writing), telecopier or telex, stating in such
notice the proposed date, aggregate principal amount of the prepayment, and
each Bank's ratable share, if any, of such prepayment, and if such notice is
given the Company or a Specified Subsidiary, as applicable, shall, prepay the
outstanding principal amount of the Syndicated Advances made as part of the
same Syndicated Borrowing in whole or, in the case of a Syndicated Borrowing
comprised solely of Base Rate Advances, ratably in part, by paying the
principal amount to be prepaid together with accrued interest thereon to the
date of prepayment; provided that each partial prepayment shall be in an
amount not less than $10,000,000 and in an integral multiple of $5,000,000. 
Each such optional prepayment shall be applied to prepay ratably the
Syndicated Advances of the several Banks included in such Syndicated
Borrowing.  If the Company or a Specified Subsidiary, as applicable, prepays
any Syndicated Borrowing consisting of or including Adjusted CD Rate Advances
or Eurodollar Rate Advances, the Company or a Specified Subsidiary, as
applicable, shall reimburse each Bank for the losses, costs, and expenses
contemplated in Section 10.4(b).  The Company or a Specified Subsidiary, as
applicable, may not, unless otherwise required hereunder, prepay any
Competitive Bid Advance without the consent of the Bank which shall have
extended such Competitive Bid Advance.  In the event the Company or a
Specified Subsidiary, as applicable, and a Bank agree to the prepayment to
such Bank of a Competitive Bid Advance, and such prepayment is made, the
Company or a Specified Subsidiary, as applicable, thereupon shall notify the
other Banks thereof.

   4.7  The Notes. (a)The Indebtedness of the Company or a Specified
Subsidiary, as applicable, resulting from Syndicated Advances made by each
Bank to the Company or a Specified Subsidiary, as applicable, shall be
evidenced by a promissory note of the Company or a Specified Subsidiary, as
applicable, payable to the order of such Bank substantially in the form of
Exhibit 4.7(a) or 5.4(b)(1) hereto (sometimes called a "Syndicated Note"). 
Each Bank may, by notice to the Company or a Specified Subsidiary, as
applicable, to be given not later than three Business Days prior to the First
Borrowing, request that its Adjusted CD Rate Advances, Base Rate Advances, and
Eurodollar Rate Advances each (or in any combination thereof) be evidenced by
separate promissory notes.  Each such promissory note shall be substantially
in the form of Exhibit 4.7(a) or 5.4(b)(1), with appropriate modifications to
reflect the fact that each such promissory note evidences solely Syndicated
Advances of the relevant Type.  Each reference in this Agreement or the Notes
to the "Notes" or the "Syndicated Notes" of such Bank shall mean and be deemed
to refer to and include any or all of such substituted promissory notes, as
the context may require.

   (b) The Indebtedness of the Company or a Specified Subsidiary, as
applicable, resulting from the Competitive Bid Advances made by each Bank to
the Company or a Specified Subsidiary, as applicable, shall be evidenced by a
promissory note of the Company or a Specified Subsidiary, as applicable,
payable to the order of such Bank substantially in the form of Exhibit 4.7(b)
or 5.4(b)(2) hereto (sometimes called a "Competitive Bid Note" and together
with the Syndicated Notes, the "Notes").

   (c) The Company or a Specified Subsidiary, as applicable, and each Bank
shall maintain records of all Advances made by such Bank to the Company or a
Specified Subsidiary, as applicable, the interest rate for such Advances, and
all payments made on account of principal thereof and, prior to any transfer
of any Note, such Bank shall endorse a record of the Advances evidenced by
such Note held by such Bank on the grid attached thereto and forming a part of
such Note.  Failure by a Bank to record on the appropriate Note any Advance or
payment shall not affect the obligation of the Company or a Specified
Subsidiary, as applicable, with respect to such Advance or payment.  If the
records of the Company or a Specified Subsidiary, as applicable, and any Bank
differ in any material respect, the records of such Bank shall govern absent
manifest error.

   4.8  Repayment.  The Company or a Specified Subsidiary, as applicable,
shall repay the principal amount of each Advance made by each Bank on the last
day of the Interest Period for such Advance, or on any earlier date required
in accordance with the terms of this Agreement.  If any Bank makes a new
Advance to the Company or a Specified Subsidiary, as applicable, on a day on
which the Company or a Specified Subsidiary, as applicable, is to repay all or
any part of any outstanding Advance from such Bank, such Bank shall apply the
proceeds of its new Advance to make such repayment, and only an amount equal
to the difference (if any) between the amount being borrowed from such Bank
and the amount being repaid to such Bank shall be made available by such Bank
to the Company or a Specified Subsidiary, as applicable, as provided in
Section 2.2 or 3.9 (as applicable) or remitted by the Company or a Specified
Subsidiary, as applicable, to such Bank as provided in Section 4.9, as the
case may be.

   4.9  Payments and Computations. (a) The Company or a Specified Subsidiary,
as applicable, shall make each payment hereunder and under the Notes not later
than 12:00 noon (Chicago time) on the day when due in U.S. Dollars to the
Banks in immediately available funds.  The Company or a Specified Subsidiary,
as applicable, shall make each payment of principal, interest, and commitment
fees as such payment becomes due, ratably (in accordance with the obligation
to which such payment relates) to the Banks for the account of their
respective Applicable Lending Offices, and shall make payment of any other
amount payable to any Bank, to such Bank for the account of its Applicable
Lending Office, in each case to be applied in accordance with the terms of
this Agreement.

   (b) All computations of interest and commitment fees shall be made on the
basis of a year of 360 days (except for computation of interest based on the
Base Rate, which shall be made on the basis of a year of 365 or 366 days, as
the case may be) for the actual number of days (including the first day but
excluding the last day) occurring in the period for which such interest or
commitment fees are payable.

   (c) 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 commitment fee, as the
case may be.  If such extension would cause such payment with respect to a
Eurodollar Rate Advance to be made in the next following calendar month, such
payment shall be made on the next preceding Business Day and the period of
time during which such payment would have been outstanding but for compliance
with this provision shall not be included in the computation of payment of
interest with respect thereto.

   4.10 Effect of Notice of Borrowing.  Subject to Section 4.11, each Notice
of Borrowing shall be irrevocable and binding on the Company or a Specified
Subsidiary, as applicable.  In the event that a Notice of Borrowing is made by
telephone and the written confirmation thereof differs in any respect from
such telephone notice, the information contained in the written confirmation
shall control for purposes of Advances to be made under this Agreement.

   4.11 Illegality; Interest Rate Inadequate or Unfair.  The obligation of
each Bank to extend an Advance on the date therefor is subject to the
following:  

   (a) If, after the date of this Agreement, the adoption of any applicable
law, rule, or regulation, or any change therein, or any change in the
interpretation or administration thereof by any governmental authority,
central bank, or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank (or its Applicable Lending
Office) with any request or directive (whether or not having the force of law)
of any such authority, central bank, or comparable agency shall make it
unlawful or impossible for any Bank (or its Applicable Lending Office) to
make, maintain, or fund its Adjusted CD Rate Advances or Eurodollar Rate
Advances, such Bank shall so notify the Company.  The Company and such Bank
shall forthwith give notice thereof to the other Banks, whereupon until such
Bank notifies the Company that the circumstances giving rise to such
suspension no longer exist, the obligation of such Bank to make Adjusted CD
Rate Advances or Eurodollar Rate Advances, as the case may be, shall be
suspended and each Adjusted CD Rate Advance or Eurodollar Rate Advance, as the
case may be, which such Bank shall thereafter be required to make hereunder
shall be made as a Base Rate Advance, which Base Rate Advance shall be made on
the same day and have the same Interest Period as the Adjusted CD Rate
Advances or Eurodollar Rate Advances, as the case may be, made by the other
Banks comprising the balance of such Borrowing.  If such Bank (i) shall
determine that it may not lawfully continue to maintain and fund any of its
outstanding Adjusted CD Rate Advances, Eurodollar Rate Advances, or
Competitive Bid Advances to maturity, (ii) shall so specify in a written
notice to the Company, and (iii) shall deliver to the Company an opinion of
counsel concurring in such determination, the Company or a Specified
Subsidiary, as applicable, shall immediately prepay in full the then
outstanding principal amount of each such Adjusted CD Rate Advance, Eurodollar
Rate Advance, or Competitive Bid Advance, as the case may be, the Company or a
Specified Subsidiary, as applicable, shall borrow a Base Rate Advance (or if
the Company or a Specified Subsidiary, as applicable, shall so elect (A) by
two Business Days' notice to such Bank, an Adjusted CD Rate Advance in the
case of an affected Eurodollar Rate Advance or Competitive Bid Advance or (B)
by three Business Days' notice to such Bank, a Eurodollar Rate Advance in the
case of an affected Adjusted CD Rate Advance or Competitive Bid Advance) in an
equal principal amount from such Bank (on which interest and principal shall
be payable contemporaneously with the related Adjusted CD Rate Advances,
Eurodollar Rate Advances, or Competitive Bid Advances of the other Banks), and
such Bank shall make such Advance.

   (b) Subject to Section 4.3(c), if by the first day of the Interest Period
for any requested Syndicated Borrowing consisting of Adjusted CD Rate Advances
or by the first Business Day before the date of any requested Borrowing
consisting of Eurodollar Rate Advances less than two Reference Banks furnish
timely information to the Company and the Banks for determining the Adjusted
CD Rate for Adjusted CD Rate Advances, or the Eurodollar Rate for Eurodollar
Rate Advances, comprising such requested Borrowing, the right of the Company
or a Specified Subsidiary, as applicable, to select Adjusted CD Rate Advances
or Eurodollar Rate Advances, as the case may be, for such Borrowing and any
subsequent Borrowing shall be suspended until at least two Reference Banks
shall furnish such information.  Upon such suspension, the Company or a
Specified Subsidiary, as applicable, shall by 1:00 p.m. (Chicago time) on such
Business Day notify the Banks whether it shall revoke the related Notice of
Borrowing or shall amend the related Notice of Borrowing to request an
unaffected Type of Advance.  If the Company or a Specified Subsidiary, as
applicable, elects to revoke such Notice of Borrowing, the obligation of the
Banks to make Advances in connection with such Notice of Borrowing shall
thereupon terminate.  If the Company or a Specified Subsidiary, as applicable,
elects to amend such Notice of Borrowing, the Company or a Specified
Subsidiary, as applicable, shall specify, in its notice thereof to the Banks,
the Type of Advances to be made in connection with such Notice of Borrowing,
which Type of Advances, unless the Company or a Specified Subsidiary, as
applicable, is not able to comply with the notice requirements set forth with
respect thereto in the first sentence of Section 2.2, shall be the Type of
Advance each Bank shall make in connection with such Notice of Borrowing.  In
the event that (i) the Company or a Specified Subsidiary, as applicable, shall
fail to give timely notice to the Banks as provided herein as to whether the
Company or a Specified Subsidiary, as applicable, shall revoke or amend a
Notice of Borrowing or (ii) the Company or a Specified Subsidiary, as
applicable, is not able to comply with the notice requirements set forth in
the first sentence of Section 2.2 with respect to a requested unaffected Type
of Advance, the Company or a Specified Subsidiary, as applicable, shall be
deemed to have requested Base Rate Advances in substitution for the affected
Advances, and each Bank obligated to participate in such Borrowing shall
extend a Base Rate Advance to the Company or a Specified Subsidiary, as
applicable, in lieu of the originally requested Type of Advance.  Each Advance
to be made in connection with an amended Notice of Borrowing pursuant to this
subsection (b) shall be made on the date specified in the original Notice of
Borrowing with respect thereto and shall have an Interest Period which is
approximately the same duration as the Interest Period originally requested
but which conforms to the conventions, if any, for the substituted Type of
Advance.

   (c) If the Majority Banks shall, by 11:00 a.m. (Chicago time) on the first
Business Day before the date of any requested Borrowing consisting of Adjusted
CD Rate Advances or Eurodollar Rate Advances, notify the Company (setting
forth in writing the reasons therefor) that the Adjusted CD Rate for Adjusted
CD Rate Advances or the Eurodollar Rate for Eurodollar Rate Advances
comprising such Borrowing will not adequately reflect the cost to such Banks
of making or funding their respective Adjusted CD Rate Advances or Eurodollar
Rate Advances for such Borrowing, the right of the Company or a Specified
Subsidiary, as applicable, to select Adjusted CD Rate Advances or Eurodollar
Rate Advances, as the case may be, for such Borrowing and any subsequent
Borrowing shall be suspended until such Majority Banks notify the Company in
writing that the circumstances causing such suspension no longer exist.  Upon
such suspension, the Company or a Specified Subsidiary, as applicable, shall
by 1:00 p.m. (Chicago time) on such Business Day notify the Banks whether it
shall revoke the related Notice of Borrowing or shall amend the related Notice
of Borrowing to request an unaffected Type of Advance.  If the Company or a
Specified Subsidiary, as applicable, elects to revoke such Notice of
Borrowing, the obligation of the Banks to make Advances in connection with
such Notice of Borrowing shall thereupon terminate.  If the Company or a
Specified Subsidiary, as applicable, elects to amend such Notice of Borrowing,
the Company or a Specified Subsidiary, as applicable, shall specify, in its
notice thereof to the Banks, the Type of Advances to be made in connection
with such Notice of Borrowing, which Type of Advance, unless the Company or a
Specified Subsidiary, as applicable, is not able to comply with the notice
requirements set forth with respect thereto in the first sentence of Section
2.2, shall be the Type of Advance each Bank shall make in connection with such
Notice of Borrowing.  In the event that (i) the Company or a Specified
Subsidiary, as applicable, shall fail to give timely notice to the Banks as
provided herein as to whether the Company or a Specified Subsidiary, as
applicable, shall revoke or amend a Notice of Borrowing or (ii) the Company or
a Specified Subsidiary, as applicable, is not able to comply with the notice
requirements set forth in the first sentence of Section 2.2 with respect to a
requested unaffected Type of Advance, the Company or a Specified Subsidiary,
as applicable, shall be deemed to have requested Base Rate Advances in
substitution for the affected Advances, and each Bank obligated to participate
in such Borrowing shall extend a Base Rate Advance to the Company or a
Specified Subsidiary, as applicable, in lieu of the originally requested
Adjusted CD Rate Advance or Eurodollar Rate Advance.  Each Advance to be made
in connection with an amended Notice of Borrowing pursuant to this subsection
(c) shall be made on the date specified in the original Notice of Borrowing
with respect thereto and shall have an Interest Period which is approximately
the same duration as the Interest Period originally requested but which
conforms to the conventions, if any, for the substituted Type of Advance.

   4.12 Increased Costs. (a) Subject to Section 4.13, if any Bank shall
determine that by reason of (i) the introduction of or any change in any
applicable law, regulation, or guideline (including the phasing-in of a
provision of any applicable law, regulation, or guideline) or in the
interpretation thereof by any governmental or other regulatory authority
charged with the administration thereof or court of competent jurisdiction
and/or (ii) compliance by such Bank with any requirement of or directive from
any central bank or other fiscal, monetary, or other regulatory authority
(whether or not having the force of law), there shall be any increase in the
cost to such Bank of agreeing or committing to make or making, funding, or
maintaining any Fixed Rate Advances or any reduction in any amount receivable
by such Bank in respect of Fixed Rate Advances under this Agreement, then the
Company or a Specified Subsidiary, as applicable, shall from time to time,
within 30 days after receipt (whenever occurring) of a certificate from such
Bank (which shall be executed by an officer thereof) pay to such Bank such
amounts as are stated therein to be required to indemnify such Bank against
such increased costs and reduction.  The certificate of such Bank as to the
amount of such increased costs or reduction shall set forth in reasonable
detail the computation of such increased costs and reduction.  The costs or
reduction shall set forth in reasonable detail the computation of such
increased costs or reduction, and shall be binding and conclusive in the
absence of manifest error.  Amounts payable pursuant to this Section 4.12(a)
shall not include amounts which the Company or a Specified Subsidiary, as
applicable, is obligated to pay pursuant to the definition of "Adjusted CD
Rate" or "Eurodollar Rate" or Section 4.14.  A Bank which demands
indemnification hereunder as a result of an increased cost or reduction
referred to herein shall deliver the certificate referred to above to the
Company demanding indemnification no later than the later of (A) the 60th day
immediately following each payment or realization by such Bank of such
increased cost or reduction (and such certificate shall certify that the
amounts set forth therein were paid or realized within such 60 day period) and
(B) the 60th day immediately following such Bank's knowledge of the incurrence
or realization by such Bank of such increased cost or reduction (and such
certificate shall so certify).

   (b) In the event that any Bank shall have determined that the adoption
after the date of this Agreement of any law, rule, guideline, or regulation
regarding the amount of capital required or expected to be maintained
("capital adequacy") by such Bank or any corporation controlling such Bank, or
any change therein or in the interpretation or application thereof after the
date of this Agreement or compliance by such Bank or any corporation
controlling such Bank with any request or directive regarding capital adequacy
(whether or not having the force of law) from any central bank or other
similar authority after the date of this Agreement, does or shall have the
effect of reducing the rate of return on such Bank's or such corporation's
capital as a consequence of its obligations hereunder to a level below that
which such Bank or such corporation could have achieved but for such adoption,
change, or compliance (taking into consideration such Bank's or such
corporation's policies with respect to capital adequacy) by an amount deemed
by such Bank to be material, then from time to time, within 30 days after
receipt (whenever occurring) of a certificate from such Bank (which shall be
executed by an officer thereof), the Company shall pay to such Bank such
additional amounts as are stated therein to be required to compensate it for
such reduction; provided, however, that in no event shall the Company be
obligated to pay such Bank any such additional amount during any quarterly
period which exceeds .25% of the average daily amount of such Bank's
Commitment Fee Base for such period.  The certificate of such Bank as to the
amount of such reduction shall set forth in reasonable detail the computation
of such reduction, and shall be binding and conclusive in the absence of
manifest error.  A Bank which demands indemnification hereunder as a result of
a reduction referred to herein shall deliver the certificate referred to above
to the Company demanding indemnification no later than the later of (A) the
60th day immediately following each realization by such Bank of such reduction
(and such certificate shall certify that the amounts set forth therein were
realized within such 60 day period) and (B) the 60th day immediately following
such Bank's knowledge of the realization by such Bank of such reduction (and
such certificate shall so certify).  If any Bank shall not be fully
compensated for any additional amounts certified to the Company pursuant to
this Section 4.12(b) by virtue of the limitation set forth in the proviso to
the first sentence of this Section 4.12(b), such Bank may elect to cancel the
unused portion of the Commitment of such Bank (a "Cancelling Bank") by giving
notice thereof (a "Cancellation Notice") to the Company specifying the
proposed effective date of cancellation (the "Bank Cancellation Date") of the
unused portion of such Cancelling Bank's Commitment, which date shall not in
any event be less than 10 Business Days following the date of such notice. 
Any outstanding Advance of such Cancelling Bank constituting a Base Rate
Advance or having an Interest Period ending on the Bank Cancellation Date
shall be paid on the Bank Cancellation Date and any other Advance of such
Cancelling Bank shall remain outstanding until the last day of the Interest
Period therefor or until otherwise required to be paid in accordance with the
terms of this Agreement.  Upon the Company's receipt of such Cancellation
Notice, one or more of the other Banks may agree, upon request of the Company,
to succeed in the aggregate to the entire Commitment of the Cancelling Bank on
the Bank Cancellation Date, which succession shall, with respect to the unused
portion of such Cancelling Bank's Commitment, become effective as of such Bank
Cancellation Date and, with respect to the remaining portion of such
Cancelling Bank's Commitment, become effective as and when such Cancelling
Bank's Advances are repaid.  On the Bank Cancellation Date, the Cancelling
Bank shall have no further Commitment and shall no longer be a "Bank" under
this Agreement for any purpose (other than in each case with respect to
Advances made by such Bank which remain outstanding after such date).

   4.13 Performance of Banks' Obligations.  Each Bank shall use its
reasonable and good faith efforts to keep apprised of all events and
circumstances that would (i) excuse or prohibit such Bank from performing its
obligation to make Eurodollar Rate Advances hereunder pursuant to Section
4.11(a) or (b) or (ii) permit such Bank to demand increased costs pursuant to
Section 4.12.  Such Bank shall, as soon as practicable after becoming aware of
any such event or circumstance, use its reasonable and good faith efforts, to
the extent permitted by law, to perform its obligations to make Eurodollar
Rate Advances through another office or lending office, and with respect to
increased costs, to mitigate such increased costs (if the use of such other
office or lending office, or such mitigation would not adversely affect the
performance of such obligations or repayment of the Advances or result in any
increased cost, loss, liability, or other disadvantage to such Bank), in
either case if by taking the action contemplated by the foregoing, such event
or circumstance would cease to exist.

   4.14 Taxes. (a) All payments made by the Company or a Specified
Subsidiary, as applicable, under this Agreement or under the Notes shall be
made free and clear of, and without deduction or withholding for or on account
of, any present and future income, stamp, or other taxes, levies, imposts,
deductions, charges, or withholdings imposed, assessed, levied, or collected
by any country or any political subdivision or taxing authority thereof or
therein but excluding taxes imposed on net income of the Bank to which such
amount is payable by the country under the laws of which such Bank is
organized or managed and controlled or any political subdivision or taxing
authority thereof or therein or the country in which such Bank's Applicable
Lending Office may be located or any political subdivision or taxing authority
thereof or therein (all such non-excluded taxes, levies, imposts, deductions,
charge, or withholdings being hereinafter called "Taxes").  If any Taxes are
required to be withheld from the amounts payable to any Bank hereunder, the
amounts so payable to such Bank shall be increased to the extent necessary to
yield to such Bank (after payment of all Taxes) interest or any such other
amounts payable hereunder at the rates or in the amounts specified in this
Agreement.  Whenever any tax is paid by the Company or a Specified Subsidiary,
as applicable, as promptly as possible thereafter, the Company or a Specified
Subsidiary, as applicable, shall send to the relevant Bank a certified copy of
any original receipt received by the Company or a Specified Subsidiary, as
applicable, showing payment thereof.  If the Company or a Specified
Subsidiary, as applicable, fails to pay any Taxes when due to the appropriate
taxing authority, the Company or a Specified Subsidiary, as applicable, shall
indemnify each Bank for any incremental taxes, interest, or penalties that may
become payable by such Bank as a result of any such failure.

   (b) Each of Chemical Bank, Continental Bank N.A., The First National Bank
of Chicago, Bank of America National Trust and Savings Association and The
Northern Trust Company represents that it is incorporated under the laws of
the United States of America or a state thereof.  Within 30 days after the
date of execution of this Agreement, each other Bank agrees that it will
deliver to the Company (i) either (A) a statement that it is incorporated
under the laws of the United States of America or a state thereof or (B) if it
is not so incorporated, a letter in duplicate in the form of Exhibit 4.14(a)
or Exhibit 4.14(b) attached hereto, as appropriate, and two duly completed
copies of United States Internal Revenue Service Form 1001 or 4224 or
successor applicable form, as the case may be, certifying in each case that
such Bank is entitled to receive payments under this Agreement without
deduction or withholding of any United States Federal income taxes, and (ii)
an Internal Revenue Service Form W-8 or W-9 or successor applicable form, as
the case may be, to establish an exemption from United States backup
withholding tax.  Each such Bank which delivers to the Company a Form 1001 or
4224 and Form W-8 or W-9 pursuant to the next preceding sentence further
undertakes to deliver to the Company two further copies of the said letter and
Form 1001 or 4224 and Form W-8 or W-9, or successor applicable forms, or other
manner of certification, as the case may be, on or before the date that any
such letter or form expires or becomes obsolete or after the occurrence of any
event requiring a change in the most recent letter and form previously
delivered by it to the Company, and such extensions or renewals thereof as may
reasonably be requested by the Company, certifying in the case of a Form 1001
or 4224 that such Bank is entitled to receive payments under this Agreement
without deduction or withholding of any United States Federal income taxes,
unless in any such case an event (including without limitation any change in
treaty, law, or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent a Bank from duly completing and delivering any such
letter or form with respect to it and such Bank advises the Company that it is
not capable of receiving payments without any deduction or withholding of
United States Federal income tax, and in the case of a Form W-8 or W-9,
establishing an exemption from United States backup withholding tax.

   (c) Without affecting its rights under this Section 4.14 or any other
provision of this Agreement, each Bank agrees that in the event that any Taxes
are imposed and required by law to be paid or to be withheld from any amount
payable to any Bank or its Applicable Lending Office with respect to which the
Company or a Specified Subsidiary, as applicable, would be obligated pursuant
to this Section 4.14 to increase any amounts payable to such Banks or to pay
any such Taxes, such Bank shall use reasonable efforts to select an
alternative Applicable Lending Office which would not result in the imposition
of such Taxes; provided, however, that no Bank shall be obligated to select an
alternative Applicable Lending Office if such Bank determines, in its sole
discretion, that (i) as a result of such selection such Bank would be in
violation of an applicable law, regulation, treaty, directive, or guideline or
would incur additional costs or expenses or (ii) such selection would be
inadvisable for regulatory reasons or inconsistent with the interests of 
such Bank.

   (d) To the extent that, as determined by any Bank in its sole discretion
and without any obligation to disclose its tax records, Taxes have been
irrevocably utilized by such Bank (either as credits or deductions) to reduce
its tax liabilities and such utilization is consistent with its overall tax
policy, such Bank shall pay to the Company or a Specified Subsidiary, as
applicable, an amount equal to such reduction obtained to the extent of such
increased amounts paid by the Company or a Specified Subsidiary, as
applicable, to such Bank as aforesaid.

   4.15 Effect of Failure to Borrow or Fund. (a)In the case of any Borrowing
which the related Notice of Borrowing specifies is to be comprised of Fixed
Rate Advances, the Company or a Specified Subsidiary, as applicable, shall
indemnify each Bank against all direct out-of-pocket losses and reasonable
expenses incurred by such Bank as a result of any failure by the Company or a
Specified Subsidiary, as applicable, to fulfill on or before the date
specified for such Borrowing the applicable conditions set forth in Article V
to the extent of all direct out-of-pocket losses and reasonable expenses
incurred by reason of the liquidation or reemployment of deposits or other
funds acquired by such Bank to fund the Advance to be made by such Bank as
part of such Borrowing when such Advance, as a result of such failure, is not
made on such date.  The Company or a Specified Subsidiary, as applicable,
shall not be liable to any Bank under this Section 4.15(a) with respect to
consequential damages arising or incurred by such Bank in connection with the
Company's or a Specified Subsidiary's, as applicable, failure to fulfill
timely the applicable conditions set forth in Article V.

   (b) Each Bank shall indemnify the Company or a Specified Subsidiary, as
applicable, against all direct out-of-pocket losses and reasonable expenses
incurred by the Company or a Specified Subsidiary, as applicable, as a result
of any failure by such Bank to make timely any Advance in the manner and at
the time such Advance is required to be made in accordance with Section 2.2 or
3.9, as applicable (but only if all of the conditions precedent to the making
of such Advances were timely satisfied or waived pursuant to Section 10.1), to
the extent of all interest and overdraft charges and all direct out-of-pocket
losses and reasonable expenses incurred by reason of the Company or a
Specified Subsidiary, as applicable, borrowing funds at a higher rate of
interest than the rate of interest applicable to any Advance not made;
provided, however, that the aggregate amount payable to the Company or a
Specified Subsidiary, as applicable, by any Bank under this Section 4.15(b)
shall not exceed the Daily Indemnity Amount for each of the first two Business
Days (and for each non-Business Day occurring prior to either of the first or
second of such Business Days) after such Bank has failed to make timely such
Advance and such failure has continued.  Beginning with the day (whether or
not a Business Day) immediately succeeding the second Business Day after any
such failure to make an Advance, the amount payable to the Company or a
Specified Subsidiary, as applicable, by any Bank in respect of each day on
which such failure has continued shall no longer be limited by the proviso in
the preceding sentence.  For purposes of this Section 4.15(b), "Daily
Indemnity Amount" shall mean the amount equal to the product of (i) the amount
of the Advance which a Bank has failed to make timely as otherwise required in
accordance with Section 2.2 or 3.9 and (ii) the Federal Funds Rate (calculated
on a per diem basis).  No Bank shall be liable to the Company or a Specified
Subsidiary, as applicable, under this Section 4.15(b) with respect to
consequential damages arising or incurred by the Company or a Specified
Subsidiary, as applicable, in connection with such Bank's failure to make
timely any Advance hereunder.

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

   4.16 Termination and Prepayment with Respect to Any Bank. (a)In addition
to the right of the Company to terminate in whole or reduce ratably in part
the respective Commitments of the Banks as described in Section 4.5 and the
right of the Company and each Specified Subsidiary to prepay Syndicated
Advances as described in Section 4.6, the Company shall have the right to
terminate the unused portion of the Commitment of any Bank and to prepay and
cause each Specified Subsidiary to prepay all outstanding Advances made by
such Bank in the manner described in this Section 4.16 if (i) such Bank shall
be an Objecting Bank or (ii) the Company shall have received notice (a
"Special Notice") from such Bank that such Bank (A) cannot extend an Adjusted
CD Rate Advance or a Eurodollar Rate Advance and shall exercise its rights
pursuant to Section 4.11(a), or (B) claims reimbursement for increased costs
pursuant to Section 4.12(a) or reduced returns pursuant to Section 4.12(b), or
(C) claims reimbursement for Taxes pursuant to Section 4.14.

   (b) Upon any Bank becoming an Objecting Bank or upon receipt by the
Company of a Special Notice from any Bank, the Company may elect to terminate
the unused portion of the Commitment of such Bank by giving notice thereof
within 30 days thereafter (a "Termination Notice") to such Bank specifying
therein (i) the name of such Bank ("Terminated Bank"), (ii) the proposed
effective date of termination ("Bank Termination Date") of the unused portion
of such Terminated Bank's Commitment, which date shall not in any event be
less than five Business Days following the date of such Termination Notice,
(iii) one or more commercial banks (each, a "Successor Bank"), each such
Successor Bank having a combined capital, surplus (or its equivalent) and
undivided profits in an amount not less than U.S. $500,000,000 (or its
equivalent in another currency), which Successor Bank or Successor Banks shall
have agreed, in the aggregate, to succeed to the entire Commitment of such
Terminated Bank on the Bank Termination Date, and (iv) whether the Company or
a Specified Subsidiary, as applicable, shall, on the Bank Termination Date,
prepay all the outstanding Advances made by such Terminated Bank.

   (c) Unless the Company shall have elected, as evidenced by its Termination
Notice, to prepay and cause each Specified Subsidiary to prepay all the
Advances made by a Terminated Bank outstanding as of the Bank Termination
Date, any Advance made by such Terminating Bank constituting a Base Rate
Advance or having an Interest Period ending on the Bank Termination Date shall
be paid on the Bank Termination Date and any other Advance made by such
Terminated Bank shall remain outstanding until the last day of the Interest
Period therefor or until otherwise required to be paid in accordance with the
terms of this Agreement (including the provisions of Section 4.6).  The
Successor Bank or Successor Banks specified by the Company in a Termination
Notice shall have agreed, prior to the Bank Termination Date, to succeed, in
the aggregate, to the entire Commitment of such Terminated Bank on the Bank
Termination Date which succession shall, with respect to the unused portion of
such Terminated Bank's Commitment as of such Bank Termination Date, become
effective as of the Bank Termination Date and, with respect to the remaining
portion of such Terminated Bank's Commitment, become effective as and when
such Terminated Bank's Advances are repaid.

   (d) If the Company shall have elected, as evidenced by its Termination
Notice, to prepay and cause each Specified Subsidiary to prepay all the
Advances made by a Terminated Bank outstanding as of the Bank Termination
Date, the Successor Bank or Successor Banks shall in the aggregate extend to
the Company and its Specified Subsidiaries, as applicable, on the Bank
Termination Date, Advances (with interest at a rate to be agreed upon by the
Company and each Successor Bank) corresponding in respective amounts to each
Advance being prepaid as of such date, each of which Advances shall have an
Interest Period beginning on the Bank Termination Date and ending on the last
day of the Interest Period of the Advance being prepaid to which it
corresponds; provided that, upon the mutual agreement of the Company and the
Successor Bank (or Successor Banks, as applicable), the Company may elect not
to require the Successor Bank (or Successor Banks, as applicable) to extend
Competitive Bid Advances in substitution for the Competitive Bid Advances
extended by the Terminated Bank.

   (e) Each such termination pursuant to this Section 4.16 shall be effective
on the Bank Termination Date proposed by the Company in the related
Termination Notice if (i) no Event of Default shall have occurred prior to
such date and be continuing on such date, (ii) in the event the Company shall
have elected to prepay and cause each Specified Subsidiary to prepay all
Advances made by such Terminated Bank outstanding as of such date, (A) the
Company and such Specified Subsidiary shall have prepaid the outstanding
aggregate amount of all Advances made by the Terminated Bank, together with
accrued interest to such date on the amount prepaid and all other amounts
payable to such Bank as of such date and (B) the Successor Bank or Successor
Banks shall have extended to the Company or such Specified Subsidiary Advances
equal in aggregate amount to the Advances of the Terminated Bank being prepaid
as required pursuant to Section 4.16(d), and (iii) each Bank shall have
received evidence that the Successor Bank or Successor Banks shall have agreed
in the aggregate to succeed to the entire Commitment of the Terminated Bank in
accordance with this Section 4.16.

   (f) Subject to subsection (e) above, on the Bank Termination Date, (i)
each Successor Bank, upon execution of an agreement with the Company
substantially in the form of Exhibit 4.16(f) attached hereto, shall become a
party to this Agreement as if such Successor Bank shall have been named on the
signature pages hereof, and such Successor Bank shall have all the rights and
obligations of a "Bank" hereunder and (ii) the Terminated Bank shall have no
further Commitment under this Agreement and shall no longer be a "Bank" under
this Agreement for any purpose (other than in each case with respect to
Advances made by such Bank which remain outstanding after such date) except
insofar as it shall be entitled to any payment or indemnification, or be
obligated to make any indemnification (including, without limitation, pursuant
to Section 4.15(b)), on account of any event which shall have occurred, or any
right or liability which shall have arisen, on or prior to the date of
repayment of such outstanding Advances.  The termination of any Bank's
Commitment and the prepayment of such Bank's Advances pursuant to this Section
4.16 shall not relieve or satisfy the obligations of the Company or a
Specified Subsidiary, as applicable, to make any such prepayments free and
clear of all Taxes, to reimburse such Bank for all increased costs pursuant to
Section 4.12, or to comply with all other terms and conditions of this
Agreement (including, without limitation, Section 10.4).  A Successor Bank
shall be subject to the Syndicated Reduction (or, in the case of more than one
Successor Bank, its ratable share of the Syndicated Reduction) of the
Terminated Bank it succeeds upon the Bank Termination Date applicable to such
successor.

   4.17 Extensions of the Termination Date. (a) The Termination Date shall be
extended by an additional year if (i) the Company shall deliver a notice in
writing to each Bank by October 31, 1993 or October 31 of any subsequent year
(if the Termination Date has been previously extended), requesting that the
Termination Date be December 31 of the third following year and (ii) by
November 30, 1993 or November 30 of any subsequent year (if the Termination
Date has been previously extended), the Majority Banks have notified the
Company in writing that they agree to the requested extension.  Failure on the
part of any Bank to respond to any such request shall be deemed to be a denial
of such request by such Bank and, with respect to any such Bank and any Banks
which shall have denied such request in writing (each such Bank being referred
to herein as an "Objecting Bank"), the Termination Date shall, subject to
Section 4.16, continue to be the then existing Termination Date.  If the
Majority Banks have not agreed to the requested extension, the Termination
Date as to all of the Banks shall continue to be the then-existing Termination
Date.

   (b) Any Objecting Bank, the Commitment of which shall expire prior to any
extended Termination Date, shall, subject to Section 4.16, have its Advances
paid in full by the Company or a Specified Subsidiary, as applicable, on the
then-existing Termination Date, together with accrued interest thereon, and
shall have any accrued and unpaid commitment fee or other amounts payable to
it hereunder paid on such Termination Date.

                        REPRESENTATIONS AND WARRANTIES

   The Company hereby represents and warrants to each Bank that:

   6.1 Corporate Existence; Subsidiaries. (a) The Company and each
Significant Subsidiary is a corporation duly organized, validly existing, and
in good standing under the laws of its jurisdiction of incorporation and has
all requisite authority and all necessary material licenses and permits to own
its properties and to conduct the business in which it is currently engaged.

   (b) Schedule 6.1(b) attached hereto states the name of each of the
Company's Subsidiaries, its jurisdiction of incorporation, and the percentage
of its Voting Stock owned by the Company and/or its Subsidiaries, and
identifies those Subsidiaries which are Significant Subsidiaries.  The Company
and each Subsidiary has good and marketable title to all of the shares it
purports to own of the stock of each Subsidiary, free and clear in each case
of any lien with the exception of rights of first refusal granted to certain
minority shareholders in certain Foreign Restricted Subsidiaries.  All such
shares have been duly issued and are fully paid and non-assessable.

   6.2 Corporate and Governmental Authorization; No Contravention.  The
execution, delivery, and performance by the Company of this Agreement and the
Notes are within the Company's corporate powers, have been duly authorized by
all necessary corporate action, require no action by or in respect of, or
filing with, any Governmental Authority, and do not (i) contravene, or
constitute a default under, any provision of applicable law or regulation or
of the certificate of incorporation or by-laws of the Company, or of any
agreement, indenture, judgment, injunction, order, decree, or other instrument
binding upon the Company or (ii) result in the creation or imposition of any
lien on any property of the Company.

   6.3 Binding Effect.  This Agreement constitutes a valid and binding
agreement of the Company, and the Notes, when executed and delivered in
accordance with this Agreement, will constitute valid and binding obligations
of the Company, in each case enforceable against the Company in accordance
with their respective terms, except as enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, or similar laws
affecting the enforcement of creditors' rights generally and by general equity
principles (whether enforcement is sought by proceedings in equity or at law).

   6.4 Financial Information. (a) The consolidated balance sheet of the
Company and its consolidated Subsidiaries as at December 31, 1991, and the
related consolidated statements of income and cash flows and common
shareholders' investment for the fiscal year then ended, reported on by Arthur
Andersen & Co., copies of which have been delivered to each of the Banks,
present fairly the consolidated financial condition of the Company and its
consolidated subsidiaries as at such date and the consolidated results of
their operations and changes in financial position for the fiscal year then
ended, in conformity with generally accepted accounting principles
consistently applied except as noted therein.

   (b) As set forth in the Company's most recent quarterly report as filed
with the Securities and Exchange Commission on Form 10-Q, a copy of which has
been delivered to each of the Banks, the unaudited consolidated balance sheet
of the Company and its consolidated Subsidiaries as at September 30, 1992, and
the related unaudited consolidated statements of income and cash flow for the
nine-month period ended on such date, present fairly the consolidated
financial condition of the Company and its consolidated Subsidiaries as at

the financial condition or results of operations of the Company and its
consolidated Subsidiaries considered as a whole.

   6.5 Litigation.  There is no pending or, to the best of the knowledge of
the Company, threatened action or proceeding affecting the Company or any of
its Subsidiaries before any Governmental Authority which could reasonably be
expected to have a Material Adverse Effect on the financial condition or
results of operations of the Company and its consolidated Subsidiaries
considered as a whole or which purports to affect the validity or
enforceability of this Agreement or any Note.

   6.6 Taxes.  United States Federal income tax returns of the Company and
its Subsidiaries have been examined and closed through the fiscal year ended
December 31, 1985.  The Company and its Significant Subsidiaries have filed
all United States Federal income tax returns and all other material tax
returns which are required to be filed by them and have paid all taxes due
pursuant to such returns or pursuant to any assessment received by the Company
or any of its Significant Subsidiaries, except for taxes and assessments being
contested by the Company in good faith by appropriate proceedings and with
respect to which reserves in conformity with generally accepted accounting
principles have been provided on the books of the Company or its Subsidiaries,
as the case may be.  The charges, accruals, and reserves on the books of the
Company and its Significant Subsidiaries in respect of taxes or other
governmental charges are, in the opinion of the Company, adequate.

respective obligations under the minimum funding standards of ERISA and the
Code with respect to each employee pension benefit plan which is covered by
Title IV of ERISA or is subject to the minimum funding standards under Section

other event or condition exists which presents a material risk of (i)
termination by the Pension Benefit Guaranty Corporation of any single-employer
plan (as defined in Section 4001(a)(15) of ERISA) providing benefits for
employees of the Company or any Subsidiary and which has an Unfunded Liability
of more than $10,000,000 or (ii) the assessment of withdrawal liability
against the Company or any Subsidiary in connection with any multi-employer
plan (whether under Section 4203 or Section 4205 of ERISA) in excess of
$10,000,000.

Margin Stock constitutes less than 25% of the Company's consolidated assets. 
The proceeds of the Advances will be used by the Company for working capital
and other general corporate purposes; no part of the proceeds of any Advance
hereunder will be used for any purpose which violates the provisions of
Regulation U of the Board of Governors of the Federal Reserve System as now
and from time to time hereafter in effect.

   6.9 Not an Investment Company.  The Company is not an "investment company"
within the meaning of the Investment Company Act of 1940, as amended.

   6.10 No Default.  No Default has occurred and is continuing.

   6.11 Compliance with Environmental Laws.  The Company complies with all
applicable Federal, state, or local laws, statutes, rules, regulations, or
ordinances relating to public health, safety, or the environment (including,
without limitation, those relating to:  (a) releases, discharges, emissions,

management, or release of gases or liquid substances) the failure to comply
with which could reasonably be expected to have a Material Adverse Effect on
the Company, its consolidated Subsidiaries, their businesses and properties,
considered as a whole.

                                  ARTICLE VII
                                   COVENANTS

make Advances hereunder, any Advance to the Company or a Specified Subsidiary,
as applicable, remains outstanding and unpaid, or any other amount is owing by
the Company or a Specified Subsidiary, as applicable, to any Bank hereunder
(unless the Majority Banks shall otherwise consent in writing):

and effect, and will cause each Restricted Subsidiary to preserve and keep in
force and effect, its corporate existence and all licenses and permits
necessary to the proper conduct of its business, provided that the foregoing
shall not prevent any transaction permitted by Section 7.12 hereof, and
provided further that the Company may terminate the corporate existence of any
Restricted Subsidiary and any license or permit necessary to the conduct of
its business if in the opinion of the Board of Directors of the Company such
existence or the maintenance of such license or permit is no longer in the
best interest of the Company and is not prejudicial to the interests of the
Banks hereunder.

   7.2 Insurance.  The Company will maintain, and will cause each Restricted
Subsidiary to maintain, insurance coverage by financially sound and reputable
insurers in such forms and amounts and against such risks as are customary for
corporations of established reputation engaged in the same or a similar
business and owning and operating similar properties.

   7.3 Taxes, Claims for Labor and Materials, Compliance with Laws.  The
Company will promptly pay and discharge, and will cause each Restricted
Subsidiary promptly to pay and discharge, all lawful taxes, assessments, and
governmental charges or levies imposed upon the Company or such Restricted
Subsidiary, respectively, or upon or in respect of all or any material part of
the property or business of the Company of such Restricted Subsidiary, all
trade accounts payable in accordance with usual and customary business terms,

   stock under Section 7.12(b), such issuance or sale together with the sale,
   lease, or other disposition of assets of the Company and its Restricted
   Subsidiaries during the applicable period shall not constitute a
   substantial part of the assets of the Company and its Restricted

any such relief or to the appointment of or taking possession by any such
official in an involuntary case or other proceeding commenced against it, or
shall make a general assignment for the benefit of creditors, or shall fail
generally to pay its debts as they become due, or shall take any corporate
action to authorize any of the foregoing; or

   (g) An involuntary case or other proceeding shall be commenced against the
Company or any of its Significant Subsidiaries seeking liquidation,
reorganization, or other relief with respect to it or its debts under any
bankruptcy, insolvency, or other similar law now or hereafter in effect or
seeking the appointment of a trustee, receiver, liquidator, custodian, or
other similar official of it or any substantial part of its property, and such
involuntary case or other proceeding shall remain undismissed and unstayed for
a period of 60 days; or an order for relief shall be entered against the
Company or any of its Significant Subsidiaries under the Federal bankruptcy
laws as now or hereafter in effect; or

   (h) A judgement or order for the payment of money in excess of U.S.
$2,000,000 shall be rendered against the Company or any of its Subsidiaries
and, unless such judgement or order is otherwise being appropriately contested
in good faith, such judgment or order shall continue unsatisfied and unstayed
for a period of 30 days; or

   (i) A Change of Control shall have occurred and continued in effect for 30
days after written notice thereof has been given to the Company by any Bank;

   (j) At any time that any Permitted Advance is outstanding, the guaranty of
the Company set forth in Article XI shall fail to be in full force and effect
or the Company or any Person acting on behalf of the Company shall contest in
any manner the validity or enforceability of such guaranty.

   (k) The Subsidiary Guaranty shall fail to be in full force and effect, the
Company shall fail to comply with the covenant set forth in Section 7.18 with
respect to the Subsidiary Guaranty for 5 days after written notice thereof has
been given to the Company by any Bank, or the Company or any Subsidiary or any
Person acting on behalf of the Company or any Subsidiary shall contest in any
manner the validity or enforceability of the Subsidiary Guaranty.

then, in any such event but subject to the next sentence, the Majority Banks
may, by notice to the Company, (i) declare the obligation of the Banks to make
Advances hereunder to be terminated, whereupon the same shall forthwith
terminate, and/or (ii) declare the entire unpaid principal amount of any Notes
held by the Banks, all interest accrued and unpaid thereon and all other
amounts owing under this Agreement to the Banks to be forthwith due and
payable, whereupon such Notes, all such accrued interest, and all such amounts
shall become and be forthwith due and payable to the Banks, without
presentment, demand, protest, or further notice of any kind, all of which are
hereby expressly waived by the Company and each Specified Subsidiary.  In the
event of an Event of Default under paragraph (f) or (g) above, (x) the
obligations of the Banks to make Advances shall automatically be terminated
and (y) the Notes, all accrued and unpaid interest thereon and all other
amounts owing under this Agreement shall 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 Company and each Specified
Subsidiary.

                                  ARTICLE IX
                             THE BID ADVANCE AGENT

   9.1 Initial Bid Advance Agent.  Each Bank agrees that Ibis Investments,
Inc. may act as Bid Advance Agent hereunder until Ibis Investments, Inc.
resigns from such position pursuant to the provisions of Section 9.8.  In so
acting, Ibis Investments, Inc. is acting as agent for the Company and the
Specified Subsidiaries, and no Bank shall be responsible for any action or
inaction of Ibis Investments, Inc. under or in connection with this Agreement. 
Except for Sections 9.3(i), 9.4 and 9.8, the remaining provisions of this
Section 9 shall not apply to Ibis Investments, Inc., but shall only apply to
any successor Bid Advance Agent which is a Bank.

   9.2 Appointment; Delegation of Duties.  Each Bank hereby agrees that any
successor Bid Advance Agent appointed pursuant to Section 9.8 may take such
action on behalf of such Bank under the provisions of this Agreement and
exercise such powers and perform such duties as are expressly delegated to the
Bid Advance Agent by the terms of this Agreement, together with such other
powers as are reasonably incidental thereto.  Notwithstanding any provision to
the contrary elsewhere in this Agreement, the Bid Advance Agent shall not have
any duties or responsibilities except those expressly set forth herein, or any
fiduciary relationship with any Bank, and no implied covenants, functions,
responsibilities, duties, obligations, or liabilities shall be read into this
Agreement or otherwise exist against the Bid Advance Agent.  The Bid Advance
Agent may execute any of its duties under this Agreement by or through agents
or attorneys-in-fact and shall be entitled to the advice of counsel concerning
all matters pertaining to such duties.  The Bid Advance Agent shall not be
responsible for the negligence or misconduct of any agents or attorneys-in-
fact selected by it with reasonable care.

   9.3 Exculpatory Provisions.  Neither the Bid Advance Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact, or affiliates shall
be (i) liable to any Bank for any action lawfully taken or omitted to be taken
by it or such Person under or in connection with this Agreement (except for
its or such Person's own gross negligence or wilful misconduct), or (ii)
responsible in any manner to any of the Banks for any recitals, statements,
representations, or warranties made by the Company or a Specified Subsidiary,
as applicable, or any officer thereof contained in this Agreement or in any
certificate, report, statement, or other document referred to or provided for
in, or received by the Bid Advance Agent under or in connection with, this
Agreement or for the value, validity, effectiveness, genuineness,
enforceability, or sufficiency of this Agreement or for any failure of the
Company or a Specified Subsidiary, as applicable, to perform its obligations
hereunder.  The Bid Advance Agent shall not be under any obligation to any
Bank to ascertain or to inquire as to the observance or performance of any of
the agreements contained in this Agreement, or to inspect the properties,
books, or records of the Company or a Specified Subsidiary, as applicable.

   9.4 Reliance by Bid Advance Agent.  The Bid Advance Agent shall be
entitled to rely, and shall be fully protected in relying, upon any writing,
resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, telecopy, telex, or teletype message, statement, order, or other
document or conversation believed by it to be genuine and correct and to have
been signed, sent, or made by the proper Person or Persons, and upon advice
and statements of legal counsel (including, without limitation, counsel to the
Company), independent accountants and other experts selected by the Bid
Advance Agent.  The Bid Advance Agent shall be fully justified in failing or
refusing to taken any discretionary action under this Agreement unless it
shall first receive such advice or concurrence of the Banks as it deems
appropriate or it shall first be indemnified to its satisfaction by the Banks
against any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action.

   9.5 Non-Reliance on Bid Advance Agent and Other Banks.  Each Bank
expressly acknowledges that neither the Bid Advance Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact, or affiliates has
made any representations or warranties to it and that no act by the Bid
Advance Agent hereinafter taken, including any individual review of the
affairs of the Company or a Specified Subsidiary, as applicable, shall be
deemed to constitute any representation or warranty by the Bid Advance Agent
to any Bank.  Each Bank represents to the Bid Advance Agent that it has,
independently and without reliance upon the Bid Advance Agent or any other
Bank, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial, and other condition and credit-worthiness of
the Company or a Specified Subsidiary, as applicable, and made its own
decision to make its loans hereunder and enter into this Agreement.  Each Bank
also represents that it will, independently and without reliance upon the Bid
Advance Agent or any other Bank, and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
analysis, appraisals, and decisions in taking or not taking action under this
Agreement, and to make such investigation as it deems necessary to inform
itself as to the business, operations, property, financial, and other
condition and credit-worthiness of the Company or a Specified Subsidiary, as
applicable.  Except for notices expressly required to be furnished to the
Banks by the Bid Advance Agent hereunder, the Bid Advance Agent shall not have
any duty or responsibility to provide any Bank with any credit or other
information concerning the business, operations, property, financial, and
other condition of credit-worthiness of the Company or a Specified Subsidiary,
as applicable, including information of a Default or Event of Default, which
may come into the possession of the Bid Advance Agent or any of its officers,
directors, employees, agents, attorneys-in-fact, or affiliates.

   9.6 Indemnification.  The Banks agree to indemnify the Bid Advance Agent
in its capacity as such (to the extent not reimbursed by the Company and
without limiting the obligation of the Company to do so), ratably according to
their respective Commitments in effect on the date of incurrence by the Bid
Advance Agent of an indemnifiable cost hereunder, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgements,
suits, costs, expenses, or disbursements of any kind whatsoever which may at
any time (including without limitation at any time following the payment of
the Advances) be imposed on, incurred by or asserted against the Bid Advance
Agent in any way relating to or arising out of this Agreement, or any
documents contemplated by or referred to herein or the transactions
contemplated hereby or any action taken or omitted by the Bid Advance Agent
under or in connection with any of the foregoing; provided that no Bank shall
be liable for the payment of any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgements, suits, costs, expenses, or
disbursements resulting solely from the Bid Advance Agent's gross negligence
or wilful misconduct.  The agreements in this Section 9.6 shall survive the
payment of the Advances and all other amounts payable hereunder.

   9.7 Agent in Its Individual Capacity.  The Bid Advance Agent and its
affiliates may make loans to, accept deposits from and generally engage in any
kind of business with the Company or a Specified Subsidiary, as applicable, as
though the Bid Advance Agent were not the Bid Advance Agent hereunder.  With
respect to its Advances made by it, the Bid Advance Agent shall have the same
rights and powers under this Agreement as any Bank and may exercise the same
as though it were not the Bid Advance Agent, and the terms "Bank" and "Banks"
shall include the Bid Advance Agent in its individual capacity.

   9.8 Successor Bid Advance Agent.  The Bid Advance Agent may resign as Bid
Advance Agent upon 30 days' notice thereof to the Company and the Banks.  The
Bid Advance Agent shall resign as Bid Advance Agent upon 30 days' notice from
the Majority Banks to the Bid Advance Agent and to the Company requesting such
resignation.  Further, the Bid Advance Agent shall resign as Bid Advance Agent
upon 30 days' notice from the Company to the Bid Advance Agent and to the
Majority Banks requesting such resignation.  If the Bid Advance Agent shall or
shall be notified to resign as Bid Advance Agent under this Agreement, then
the Company shall appoint from among the Banks a successor agent for the Banks
which successor agent shall be approved by the Majority Banks, whereupon, if
such successor agent is willing to accept such appointment, such successor
agent shall succeed to the rights, powers, and duties of the Bid Advance
Agent, and the term "Bid Advance Agent" shall mean such successor agent
effective upon its appointment, and the former Bid Advance Agent's rights,
powers, and duties as Bid Advance Agent shall be terminated, without any other
or further act or deed on the part of such former Bid Advance Agent or any of
the parties to this Agreement.  After any retiring Bid Advance Agent's
resignation hereunder as Bid Advance Agent, the provisions of this Article IX
shall to the extent previously applicable to such Bid Advance Agent inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Bid Advance Agent under this Agreement.

   Anything contained in this Agreement to the contrary notwithstanding, if a
successor agent is appointed as a result of the resignation of the Bid Advance
Agent pursuant to the second sentence of this Section 9.8, then the costs
incurred by such successor agent (including the reasonable fees of counsel to
such successor agent) in connection with its preparation to perform its
obligations hereunder in such capacity shall be paid by those Banks which
shall have delivered the applicable resignation notice to the Bid Advance
Agent and the Company.

                                   ARTICLE X
                                 MISCELLANEOUS

   10.1 Amendments.  Subject to the next two sentences, no amendment or
waiver of any provision of this Agreement or any of the Notes, nor consent to
any departure by the Company or a Specified Subsidiary, as applicable,
therefrom, shall in any event be effective unless the same shall be in writing
and signed by the Majority Banks, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given.  No amendment, waiver, or consent shall, unless in writing and signed
by all the Banks, do any of the following:  (i) waive any of the conditions
specified in Article V (if and to the extent that the Borrowing which is the
subject of such waiver is not a Refunding Borrowing), (ii) change the
Commitments of the Banks or subject the Banks to any additional obligations,
(iii) change the principal of, or interest on, any of the Notes or any
commitment fees or other amounts payable hereunder, (iv) change any date fixed
for any payment in respect of principal of, or interest on, the Notes or any
commitment fees or other amount payable hereunder, (v) change the percentage
of the Commitments or of the aggregate unpaid principal amount of the Notes,
or the number of Banks, which shall be required for the Banks or any of them
to take any action hereunder, (vi) amend or otherwise modify any provision of
Article XI or release the Company from any of its obligations thereunder,
(vii) amend or otherwise modify any provision of the Subsidiary Guaranty or
release any Subsidiary from its obligations thereunder (except as permitted
hereunder or thereunder), or (viii) amend this Section 10.1.  No amendment,
waiver, or consent shall, unless in writing and signed by the Bid Advance
Agent in addition to the Banks required hereinabove to take such action,
affect the rights or duties of the Bid Advance Agent under this Agreement.

   10.2 Notices, etc.  All notices and other communications provided for
hereunder shall, unless otherwise stated herein, be in writing (including by
telex, telegram or telecopier) and mailed, certified mail, return receipt
requested, or delivered personally, or delivered by overnight courier service,
if to the Company or a Specified Subsidiary, as applicable, at the address set
forth for the Company on the signature pages hereof; if to the initial Bid
Advance Agent, at the address set forth for the Bid Advance Agent on the
signature pages hereof, and, if any successor Bid Advance Agent is a Bank, at
the Domestic Lending Office specified in its capacity as a Bank; and if to any
Bank, at its Domestic Lending Office, or at such other address as shall be
designated by such party in a written notice to the other parties hereto. 
Subject to the next sentence, all such notices and communications shall be
effective, in the case of written notice, when deposited in the mail, postage
prepaid, if mailed, or upon delivery, if delivered personally, or one Business
Day after delivery to the courier, if delivered by overnight courier service,
and, in the case of notice by telex, telegram or telecopier, when sent
addressed as set forth above.  All notices and communications pursuant to
Articles II, III, VIII and IX shall not be effective until they are received
by the addressee.

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

   10.4 Costs and Expenses; Indemnification. (a) The Company agrees to pay
the reasonable fees and disbursements of Mayer, Brown & Platt as special
counsel to the Banks in connection with the preparation, execution, delivery,
and any amendment of this Agreement, the Notes and the other documents to be
delivered hereunder.  The Company further agrees to pay on demand all direct
out-of-pocket losses, and reasonable out-of-pocket expenses, if any (including
reasonable fees and disbursements of counsel, including reasonable staff
counsel costs), of any Bank and of the Bid Advance Agent in connection with
the enforcement (whether by legal proceedings, negotiation or otherwise) of
this Agreement, the Notes and the other documents delivered hereunder.

   (b) If, due to payments made by the Company or a Specified Subsidiary, as
applicable, prior to the maturity of the Notes pursuant to Sections 4.6, 4.16
or 8.1 (but excluding prepayments pursuant to Section 4.11(a)), any Bank
receives payments of principal of any Fixed Rate Advance other than on the
last day of the Interest Period for such Advance, the Company or a Specified
Subsidiary, as applicable, shall, upon demand by such Bank, pay to such Bank
any amounts required to compensate such Bank for any additional direct out-of-
pocket losses, costs, or expenses, including, without limitation, any such
loss, cost, or expense incurred by reason of the liquidation or reemployment
of deposits or other funds acquired by any Bank to fund or maintain such
Advance.

   (c) Subject to the next sentence, the Company agrees to indemnify and hold
harmless each Bank and each of their respective directors, officers, and
employees from and against any and all claims, damages, liabilities, and
expenses (including, without limitation, reasonable fees and disbursements of
counsel, including reasonable staff counsel costs) which may be incurred by or
asserted against such Bank or any such director, officer, or employee in
connection with or arising out of any investigation, litigation, or proceeding
(i) related to any transaction or proposed transaction (whether or not
consummated) in which any proceeds of any Borrowing are applied or proposed to
be applied, directly or indirectly, by the Company or a Specified Subsidiary,
as applicable, whether or not such Bank or any such director, officer, or
employee is a party to such transaction or (ii) related to the Company's
entering into this Agreement, or to any actions or omissions of the Company,
any of its Subsidiaries or Affiliates or any of its or their respective
officers, directors, or employees in connection therewith.  The Company shall
not be required to indemnify any such indemnified Person from or against any
portion of such claims, damages, liabilities, or expenses (x) arising out of
the gross negligence or willful misconduct of such indemnified Person or (y)
that result from the violation by any Bank of any law or judicial order.

   10.5 Right of Set-Off.  Upon (i) the occurrence and during the continuance
of any Event of Default and (ii) the acceleration of the Notes pursuant to the
provisions of Section 8.1, each Bank is hereby authorized at any time and from
time to time, to the fullest extent permitted by law, to set off and apply any
and all deposits (general or special, time or demand, provisional or final) at
any time held and other indebtedness at any time owing by such Bank to or for
the credit or the account of the Company or a Specified Subsidiary, as
applicable, against any and all of the obligations of the Company or a
Specified Subsidiary, as applicable, now or hereafter existing under this
Agreement and the Notes held by such Bank, irrespective of whether or not such
Bank shall have made any demand under this Agreement and such Notes and of
whether or not such obligations may be matured.  Each Bank agrees promptly to
notify the Company or a Specified Subsidiary, as applicable, after any such
set-off and application made by such Bank, but the failure to give such notice
shall not affect the validity of such set-off and application.  The rights of
each Bank under this Section 10.5 are in addition to other rights and remedies
(including, without limitation, other rights of set-off) which such Bank may
have.

   10.6 Sharing of Payments, etc. (a)If on any day that a Pro Rata Sharing
Event (as defined below) is not in effect, the amounts paid by the Company and
the Subsidiaries hereunder or in connection herewith are insufficient to pay
in full all amounts due and payable hereunder on such day, such payments shall
be distributed as follows (notwithstanding that any Bank may make a different
application of any such amount on its books and records):  first, to the
payment of the principal of Advances which are then due and payable, ratably
among the Banks in accordance with the aggregate amount of such Advances owed
to each of them; second, to the payment of interest which is then due and
payable in respect of all Advances, ratably among the Banks in accordance with
the aggregate amount of such interest owed to each of them; third, to the
payment of any commitment fees which are then due and payable, ratably among
the Banks in accordance with the aggregate amount of such fees owed to each of
them; and fourth, to the payment of any other amounts which are then due and
payable by the Company or any Subsidiary to any Bank hereunder or in
connection herewith, ratably among the Banks in accordance with the aggregate
amount owed to each of them.

   (b) On any day that a Pro Rata Sharing Event is in effect, all amounts
paid by the Company and its Subsidiaries hereunder or in connection herewith
shall be distributed as follows (notwithstanding that any Bank may make a
different application of any such amount on its books and records):  first, to
the payment of any accrued and unpaid commitment fees, ratably among the Banks
in accordance with the aggregate amount of such fees owed to each of them;
second, to the payment of principal of and interest accrued on all Advances,
ratably among the Banks in accordance with the aggregate amount of principal
of and interest on the Advances owed to each of them; and third, to the
payment of any other amounts owed by the Company or any Subsidiary hereunder
or in connection herewith, ratably among the Banks according to the aggregate
amount owed to each of them.

   (c) If any Bank shall obtain any payment or other recovery (whether
voluntary, involuntary, through the exercise of any right of set-off, or
otherwise) hereunder on account of principal of or interest on any Advance, or
any fees or other amounts payable hereunder, in excess of the share of
payments and other recoveries such Bank would have received if such payment or
recovery had been distributed in accordance with the provisions of clauses (a)
and (b) of this Section 10.6, such Bank shall purchase from the other Banks
such participations in the Advances of each other Bank (or other amounts owed
to each other Bank) as shall be necessary to cause the purchasing Bank to
share the excess payment with each other Bank in accordance with the
provisions of clauses (a) and (b) of this Section 10.6; provided, however,
that if all or any portion of the excess payment or other recovery is
thereafter received from such purchasing Bank, the purchase shall be rescinded
and the purchase price restored to the extent of such recovery, but without
interest.  The Company agrees that any Bank so purchasing a participation from
another Bank pursuant to this Section 10.6 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 Bank were the
direct creditor of the Company or a Specified Subsidiary, as applicable, in
the amount of such participation.  Nothing contained herein shall require any
Bank to exercise any right it may have of set-off, bankers' lien, counterclaim
or similar right or shall affect the right of any Bank to exercise, and retain
the benefits of exercising, any such right with respect to any other
indebtedness or obligation of the Company or a Specified Subsidiary, as
applicable, not evidenced by this Agreement or the Notes.  If under any
applicable bankruptcy, insolvency or other similar law, any Bank obtains a
secured claim in lieu of a set-off or other payment to which this Section 10.6
would apply, such Bank shall, to the extent practicable, exercise its rights
in respect of such secured claim in a manner consistent with the rights of the
Banks entitled under this Section 10.6 to share in the benefits of any
recovery of such secured claim.

   (d) For purposes of this Section 10.6, a Pro Rata Sharing Event exists
when (i) an Event of Default described in clause (f) or (g) of Section 8.1 has
occurred and is continuing or (ii) any other Event of Default exists and any
Bank has delivered a written notice to the Company (with a copy to each other
Bank), which notice has not been rescinded, declaring that a Pro Rata Sharing
Event exists.

   10.7 Binding Effect; Successors and Assigns. (a)This Agreement shall
become effective when it shall have been executed by the Company, the Bid
Advance Agent and each Bank.  This Agreement thereafter shall be binding upon
and inure to the benefit of the Company, each Specified Subsidiary, the Bid
Advance Agent, and each Bank and their respective successors and assigns,
except that neither the Company nor any Specified Subsidiary shall have the
right to assign its rights hereunder or any interest herein without the prior
written consent of all of the Banks.

   (b) Each Bank may, with the prior written consent of the Company, which
consent shall not be unreasonably withheld, assign all or any part of, or
interest in, such Bank's Commitment, rights and obligations hereunder and
under the Notes to one or more institutional lenders or investors, and in such
case such Bank shall be relieved of its obligations hereunder with respect to
all or any such part of its Commitment so assigned.  The Company or a
Specified Subsidiary, as applicable, may, for all purposes of this Agreement,
treat any Bank as the holder of any Note drawn to its order (and owner of the
Advances evidenced thereby) until the Company receives (i) written notice of
the assignment thereof signed by such Bank, (ii) the written agreement of the
assignee that such assignee assumes all obligations hereunder and is bound
hereby as it would have been if it had been an original Bank party hereto, and
(iii) the documents from the assignee required pursuant to Section 4.14(b). 
Upon consummation of any assignment pursuant to this Section 10.7(b), the
assignor Bank and the Company shall make appropriate arrangements so that, if
required, a replacement Note or Notes is issued to such assignor Bank and a
new Note or Notes, or as appropriate a replacement Note or Notes, is issued to
the assignee, in each case in principal amounts reflecting their resulting
respective interests hereunder.

   (c) Each Bank may grant participations in its Commitment, Advances, and
its Notes or any other interest of such Bank hereunder to one or more
institutional lenders or investors.  Any agreement pursuant to which any Bank
may grant a participation in its rights with respect to its Commitment or any
particular Advance or Advances shall provide that, with respect to its
Commitment or any such Advance or Advances, such Bank shall retain the sole
right and responsibility to enforce the obligations of the Company or a
Specified Subsidiary, as applicable, relating to its Commitment or such
Advance or Advances including, without limitation, the right to approve any
amendment, modification, or waiver of any provision of this Agreement;
provided that such participation agreement may provide that such Bank will not
agree to any modification, amendment or waiver of this Agreement without the
consent of the participant that would (i) reduce the rate of interest on such
Advance or Advances or any fees hereunder, or (ii) postpone or extend the date
fixed for any payment of principal of or interest on any such Advance or
Advances or any fees hereunder.

   (d) Notwithstanding any other provision of this Agreement, any Bank may at
any time pledge or assign any Note or its rights under this Agreement to any
Federal Reserve Bank without notice to or consent from the Company or any
Specified Subsidiary.

   10.8 Contingent Appointment of Agent.  If at any time prior to the
Termination Date the Credit Ratings shall fall to BB- (S&P) and Ba3 (Moody's)
or lower in either case, the Company and the Specified Subsidiaries agree that
the Majority Banks may appoint, in writing, one of the Banks as agent (the
"Contingency Agent") for the Banks, which appointment shall be accepted by the
Contingency Agent in writing and shall be reasonably acceptable to the
Company.  The Contingency Agent may, but shall not be required to, be a Bank
which is then acting as Bid Advance Agent.  The Contingency Agent shall
immediately begin to perform those functions which the Company or a Specified
Subsidiary, as applicable, would otherwise have performed in connection with
providing notifications to the Banks under Section 2.2, determining interest
rates under Section 4.3 and collecting and remitting payments for the account
of the Banks under Section 4.9, shall at the request, or may with the consent,
of the Majority Banks, by notice to the Company, take the actions specified
under Section 8.1 hereof and shall otherwise be authorized to take any action
under this Agreement on behalf of the Banks which it may be  directed to take
by the Majority Banks.  In the event that a Contingency Agent is appointed
pursuant to this Section 10.8, the Banks agree among themselves (and the
Contingency Agent by its acceptance of its appointment as such agrees) that
the provisions set forth in Exhibit 10.8 hereto shall automatically become a
part of this Agreement as if fully set forth in this place.  The Company
agrees to pay the expenses of and indemnify the Contingency Agent to the same
extent as it has agreed to do with respect to the Bid Advance Agent under
Section 10.4.

   10.9 Participation in Unfriendly Takeovers.  Each Bank shall be given
notice by the Company at least 10 Business Days prior to the date on which the
Company intends to use the proceeds from any Advance to finance in whole or in
part an Unfriendly Takeover.  Each Bank shall then have five Business Days
after receipt of the notice from the Company within which to give written
notice to the Company that it declines to participate in the financing of such
Unfriendly Takeover (a "Declining Bank").  Any Bank failing to give such
written notice within the specified time period shall automatically be deemed
to be a Declining Bank with respect to that Unfriendly Takeover (unless such
Bank subsequently notifies the Company in writing that it is willing to
participate in that Unfriendly Takeover).  Notwithstanding anything in this
Agreement to the contrary, the Company shall not request any Declining Bank,
and no Declining Bank shall be required, to make any Advance the proceeds of
which will be used directly or indirectly to finance in whole or in part an
Unfriendly Takeover.  Any provision of this Agreement which would otherwise
require ratable or pro-rata treatment of the Banks shall not be deemed to
include a Declining Bank with respect to any Advance made to finance in whole
or in part an Unfriendly Takeover.  "Unfriendly Takeover" shall mean the
acquisition of, or the attempt to acquire, by the Company or any Subsidiary of
the Company, individually or collectively, 20% or more of any class of voting
securities of any Person, which acquisition is not approved by the board of
directors of such Person.

   10.10 Governing Law.  This Agreement and the Notes shall be governed by,
and construed in accordance with, the internal laws (as distinguished from the
conflicts of laws rules) of the State of Illinois.

   10.11 Execution in Counterparts.  This Agreement may be executed in any
number of counterparts and by different parties hereto 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
agreement.

   10.12 Limited Role of Banks.  The relationship between the Company and the
Specified Subsidiaries, on the one hand, and the Banks, on the other hand,
shall be solely that of borrowers and lenders, respectively.  No Bank shall
have any fiduciary responsibility to the Company or any Specified Subsidiary,
and no joint venture exists hereunder or in connection herewith between the
Company or any Specified Subsidiary and any Bank.

   10.13 Integration.  This Agreement represents the agreement of the
Company, the Specified Subsidiaries and the Banks with respect to the subject

                                  ARTICLE XI
                                   GUARANTY

   11.1    Guaranty of Payment.  The Company hereby unconditionally
guarantees the full and prompt payment to the Banks when due, upon demand, at
maturity, or by reason of acceleration or otherwise, of any and all Advances
from time to time made to any Specified Subsidiary (without deduction of any
applicable taxes, if any), together with all interest thereon and any premium,
penalties, and other amounts payable in connection therewith (the "Guaranteed
Indebtedness").

   11.2    The Banks' Costs and Expenses.  The Company agrees to pay on
demand all costs and expenses of every kind incurred by the Banks:

   (a) in enforcing the guaranty contained in this Article XI (this
"guaranty");

   (b) in collecting any of the Guaranteed Indebtedness from any Specified
Subsidiary or the Company;

   (c) for any other purpose related to the Guaranteed Indebtedness.

   "Costs and expenses" as used in the preceding sentence shall include,
without limitation, attorneys' fees incurred by any Bank (including the
allocated costs of internal counsel) in retaining counsel for advice, suit,
appeal, any insolvency, or other proceedings under the Federal Bankruptcy Code
or otherwise, or for any purpose specified in the preceding sentence.

   11.3 Nature of Guaranty:  Continuing, Absolute, and Unconditional. (a)This
guaranty is and is intended to be a continuing guaranty of payment of the
Guaranteed Indebtedness, independent of and in addition to any other guaranty,
indorsement, collateral, or other agreement held by the Banks therefor or with
respect thereto, whether or not furnished by the Company.  The Company waives
all rights of subrogation (whether contractual, under Section 509 of the
United States Bankruptcy Code or otherwise) to the claims of the Banks against
any Specified Subsidiary and all contractual, statutory, or common law rights
of reimbursement, contribution, or indemnity from any Specified Subsidiary
which may otherwise have arisen in connection with this guaranty.

   (b) This guaranty is absolute and unconditional and shall not be changed
or affected by any representation, oral agreement, act, or thing whatsoever,
except as herein provided.

   11.4 Certain Rights and Obligations. (a) The Company authorizes the Banks,
without notice, demand, or any reservation of rights against the Company and
without affecting the Company's obligations hereunder, from time to time:  

     (i)   to renew, extend, increase, accelerate, or otherwise change the
   time for payment of, the terms of or the interest on the Guaranteed
   Indebtedness or any part thereof, or grant other indulgences to any
   Specified Subsidiary or others;  

     (ii)  to accept from any Person and hold collateral for the payment of
   the Guaranteed Indebtedness or any part thereof, and to modify, exchange,
   enforce, or refrain from enforcing, or release such collateral or any part
   thereof; 

     (iii)  to accept and hold any indorsement or guaranty of payment of the
   Guaranteed Indebtedness or any part thereof, and to discharge, release, or
   substitute any such obligation of any such indorser or guarantor, or any
   Person who has given any security interest in any collateral as security
   for the payment of the Guaranteed Indebtedness or any part thereof, or any
   other Person in any way obligated to pay the Guaranteed Indebtedness or
   any part thereof, and to enforce or refrain from enforcing, or compromise
   or modify, the terms of any obligation of any such indorser, guarantor, or
   Person; 

     (iv)  to dispose of any and all collateral securing the Guaranteed
   Indebtedness, if any, in any manner as the Majority Banks, in their sole
   discretion, may deem appropriate, and to direct the order or manner of
   such disposition and the enforcement of any and all endorsements and
   guaranties relating to the Guaranteed Indebtedness or any part thereof as
   the Majority Banks in their sole discretion may determine; 

     (v)   to determine the manner, amount, and time of application of
   payments and credits, if any, to be made on all or any part of any
   component or components of the Guaranteed Indebtedness (whether principal,
   interest, costs, expenses, or otherwise);

     (vi)  to grant or continue credit from time to time by the Banks to any
   Specified Subsidiary without notice to or authorization from the Company
   regardless of such Specified Subsidiary's financial or other condition at
   the time of any such grant or continuation, and in connection therewith
   the Banks shall have no obligation to disclose or discuss with the Company
   their assessment of the financial condition of any Specified Subsidiary;
   and 

     (vii)   to take advantage or refrain from taking advantage of any
   security or accept or make or refrain from accepting or making any
   compositions or arrangements when and in such manner as the Majority
   Banks, in their sole discretion, may deem appropriate and generally do or
   refrain from doing any act or thing which might otherwise, at law or in
   equity, release the liability of the Company as a guarantor or surety in
   whole or in part, and in no case shall any Bank be responsible or shall
   the Company be released either in whole or in part for any act or omission
   in connection with any Bank having sold any security at an under value.

   (b) If any default shall be made in the payment of any of the Guaranteed
Indebtedness, the Company hereby agrees to pay the same in full to the extent
hereinafter provided:  

     (i)   without deduction by reason of any setoff, defense (other than
   payment) or counterclaim of the applicable Specified Subsidiary; 

     (ii)  without requiring protest or notice of nonpayment or notice of
   default to Company, to the applicable Specified Subsidiary or to any other
   Person; 

     (iii)   without demand for payment or proof of such demand; 

     (iv)  without requiring the Banks to resort first to the applicable
   Specified Subsidiary (this being a guaranty of payment and not of
   collection) or to any other guaranty or any collateral which any Bank may
   hold; 

     (v)   without requiring notice of acceptance hereof or assent hereto by
   any Bank; and 

     (vi)  without requiring notice that any of the Guaranteed Indebtedness
   has been incurred or of the reliance by the Banks upon this guaranty; all
   of which the Company hereby waives.

   (c) The Company's obligation hereunder shall not be affected by any of the
following, all of which the Company hereby waives:  

     (i)   any defense arising by reason of the cessation from any cause
   whatsoever of liability of the applicable Specified Subsidiary, including,
   without limitation, any failure, negligence, or omission by the Banks in
   enforcing their claims against such Specified Subsidiary; 

     (ii)  any release, settlement, or compromise of any obligation of any
   Specified Subsidiary; 

     (iii)   the invalidity or unenforceability of any of the Guaranteed
   Indebtedness; 

     (iv)  any change of ownership of any Specified Subsidiary or the
   insolvency, bankruptcy, or any other change in the legal status of any
   Specified Subsidiary; 

     (v)   the change in or the imposition of any law, decree, regulation, or
   other governmental act which does or might impair, delay, or in any way
   affect the validity, enforceability, or the payment when due of the
   Guaranteed Indebtedness; or 

     (vi)  the failure of any Specified Subsidiary or the Company to maintain
   in full force, validity, or effect or to obtain or renew when required all
   governmental and other approvals, licenses, or consents required in
   connection with the Guaranteed Indebtedness or this guaranty, or to take
   any other action required in connection with the performance of all
   obligations pursuant to the Guaranteed Indebtedness or this guaranty.

   A. Continuing Guaranty.  If after receipt of any payment of all or any
part of the Guaranteed Indebtedness, any Bank is for any reason compelled by
court order to surrender such payment to any person or entity, because such
payment is determined to be void or voidable as a preference, impermissible
setoff, or a diversion of trust funds, or for any reason, this guaranty shall
continue in full force (or, if applicable, be reinstated) notwithstanding any
contrary action which may have been taken by any Bank in reliance upon such
payment, and any such contrary action so taken shall be without prejudice to
the Banks' rights under this guaranty and shall be deemed to have been
conditioned upon such payment having become final and irrevocable. 

   B. Guaranty of Performance.  The Company also guarantees the full, prompt,
and unconditional performance of all obligations and agreements of every kind
owed or hereafter to be owed by each Specified Subsidiary to the Banks.  Every
provision for the benefit of the Banks contained in this guaranty shall apply
to the guarantee of performance given in this paragraph.
   
   IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed and delivered by their proper and duly authorized officers as of
the day and year first above written.

                    [FORM OF OPINION OF COMPANY'S COUNSEL]


December 14, 1992


To each of the Banks parties 
  to the Credit Agreement
  dated as of December 4, 1992
  among CBI Industries, Inc.,
  said Banks, and to IBIS INVESTMENTS, INC.
  as Bid Advance Agent

Gentlemen:

      This opinion is furnished to you pursuant to Section 5.2(e) of the
Credit Agreement dated as of December 4, 1992 (the "Credit Agreement") among
CBI Industries, Inc. (the "Company"), the Specified Subsidiaries party
thereto, the Banks parties thereto, and Ibis Investments, Inc., as Bid Advance
Agent for said Banks.  Terms defined in the Credit Agreement are used herein
as therein defined.

      As Senior Vice President and General Counsel to the Company, I have
participated in the preparation, execution, and delivery of the Credit
Agreement.  In that connection I have examined:

      1.    The Credit Agreement; 

      2.    The documents furnished by the Company pursuant to Section 5.2 of
            the Credit Agreement;

      3.    The Subsidiary Guaranty and the documents furnished by the
            Subsidiaries party thereto pursuant to Section 5.5 of the Credit
            Agreement; and

      4.    The opinion of even date herewith of Robert W. Dudley, Senior Vice
            President and General Counsel of Liquid Carbonic Industries
            Corporation.

      In addition, I have reviewed such of the corporate proceedings of the
Company and its Subsidiaries, and have examined such documents, corporate
records, certificates of public officials and of officers of the Company and
its Subsidiaries, agreements, and other instruments as I have deemed necessary
for the purpose of this opinion.  I have assumed the due execution and
delivery, pursuant to due authorization, of the Credit Agreement by the Banks
and the Bid Advance Agent, and the authenticity of all documents submitted to
me as originals and the conformity to the original documents of all documents
submitted to me as certified, conformed, or photostatic copies.

      To the extent that my opinion expressed below involves conclusions as to
the matters set forth in the above-mentioned opinion of Robert W. Dudley,
Esq., a copy of which is attached, I have assumed without independent
investigation the correctness of the matters set forth therein.

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

      1.    Each of the Company and its U.S. Restricted Subsidiaries is a
            corporation duly incorporated, validly existing, and in good
            standing under the laws of its jurisdiction of incorporation and
            has the corporate power and authority to carry on its business as
            now being conducted and to own its properties.  Each of the
            Company and its U.S. Restricted Subsidiaries has been duly
            qualified as a foreign corporation for the transaction of business
            and is in good standing under the laws of each other jurisdiction
            in the United States in which the failure to so qualify could
            reasonably be expected to have a materially adverse effect on the
            financial condition or operations of the Company and its
            Subsidiaries considered as a whole.

      2.    The execution, delivery, and performance by the Company of the
            Credit Agreement and the Notes are within the Company's corporate
            powers and have been duly authorized by all necessary corporate
            action on the part of the Company, the execution, delivery and
            performance of the Subsidiary Guaranty by each Subsidiary party
            thereto are within each such Subsidiary's corporate powers and
            have been duly authorized by all necessary corporate action on the
            part of each such Subsidiary, and such execution, delivery and
            performance do not, in any such case, (i) contravene, or
            constitute a default under, the certificate of incorporation or
            by-laws of the Company or any such Subsidiary, or any judgment,
            law, rule, or regulation known to me to be applicable to the
            Company or any such Subsidiary, or any indenture, mortgage, deed
            of trust, or other material agreement or instrument by which the
            Company or any of its Subsidiaries is bound or (ii) result in the
            creation of any lien, charge, or encumbrance upon any of the
            property or assets of the Company or any of its Subsidiaries.  The
            Credit Agreement and the Notes have been duly executed and
            delivered on behalf of the Company and the Subsidiary Guaranty has
            been duly executed and delivered by each Subsidiary party thereto.

      3.    No authorization, approval, or other action by, and no notice to
            or filing with, any Governmental Authority is required for the due
            execution, delivery, and performance (a) by the Company of the
            Credit Agreement and the Notes or (b) by any Subsidiary of the
            Subsidiary Guaranty.

      4.    The Credit Agreement and the Notes are valid and legally binding
            obligations of the Company enforceable against the Company in
            accordance with their respective terms, subject, as to
            enforcement, to bankruptcy, insolvency, reorganization, and other
            laws of general applicability relating to or affecting creditors'
            rights and to general equity principles.

      5.    The Subsidiary Guaranty is the legal, valid and binding obligation
            of each Subsidiary which is a party thereto enforceable against
            each such Subsidiary in accordance with its terms, subject, as to
            enforcement, to bankruptcy, insolvency, reorganization, and other
            laws of general applicability relating to or affecting creditors'
            rights and to general equity principles.

      6.    There is no pending or, to the best of my knowledge, threatened
            action or proceeding against the Company or any of its
            Subsidiaries before any Governmental Authority which is likely to
            have a materially adverse effect upon the financial condition or
            operations of the Company and its Subsidiaries considered as a
            whole which has not been previously disclosed or which purports to
            affect the legality, validity, or enforceability of the Credit
            Agreement, the Notes or the Subsidiary Guaranty.

      I am aware that Mayer, Brown & Platt will rely upon the opinions set
forth in paragraphs 1, 2, and 3 of this opinion in rendering their opinion
furnished pursuant to Section 5.2(f) of the Credit Agreement and consent
thereto.

                           Very truly yours,



                           Charles O. Ziemer
                           Senior Vice President and General Counsel


                                             EXHIBIT 5.2(f)

                  [FORM OF OPINION OF BANK'S SPECIAL COUNSEL]


To Each of the Banks Listed
on Schedule A attached hereto

Ladies and Gentlemen:

      We have acted as special counsel to the banking institutions listed on
Schedule A hereto in connection with the preparation, execution, and delivery
of the Credit Agreement dated as of December 4, 1992 (the "Credit Agreement")
among CBI Industries, Inc., a Delaware corporation, (the "Company"), the
Specified Subsidiaries party thereto, the Banks party thereto (the "Banks"),
and Ibis Investments, Inc., as Bid Advance Agent.  Unless otherwise defined
herein, capitalized terms used herein have the meanings assigned to those
terms in the Credit Agreement.

      In this connection, we have examined the following documents:

      (1)   An executed Credit Agreement;

      (2)   The Notes delivered to the Banks by the Company pursuant to
            Section 5.2(a) of the Credit Agreement (the Credit Agreement and
            the Notes are hereinafter collectively referred to as the "Loan
            Documents"); 

      (3)   The Subsidiary Guaranty executed by various subsidiaries; and

      (4)   The opinion of even date herewith of Charles O. Ziemer, Esq.,
            Senior Vice President and General Counsel of the Company.

      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 of the originals of all such documents submitted
to us as copies.  We have also assumed that each of the Banks and the Bid
Advance Agent has duly executed and delivered, with all necessary power and
authority (corporate and otherwise), the Credit Agreement.

      To the extent that our opinion expressed below involves conclusions as
to the matters set forth in the above-mentioned opinion of Charles O. Ziemer,
Esq., we have assumed without independent investigation the correctness of the
matters set forth therein.

      Based upon the foregoing examination of documents and assumptions and
upon such other investigation as we have deemed necessary, we are of the
following opinion:

      1.    The legal opinion of Charles O Ziemer, Esq. is substantially
            responsive to the requirements of Section 5.2(e) of the Credit
            Agreement.

      2.    The Notes are substantially responsive to the requirements of
            Section 5.2(a) of the Credit Agreement.

      3.    The Loan Documents are the legal, valid, and binding obligations
            of the Company enforceable against the Company in accordance with
            their respective terms.

      4.    The Subsidiary Guaranty is the legal, valid and binding obligation
            of each Subsidiary which is a party thereto, enforceable against
            each such Subsidiary in accordance with its terms.

      Our opinions expressed in Paragraphs 3 and 4 above are subject to the
following qualifications:

      (a)   Our opinions are subject to the effect of any applicable
            bankruptcy, insolvency, reorganization, fraudulent conveyance,
            moratorium, or similar law affecting the enforcement of creditors'
            rights generally and to the effect of general principles of equity
            (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 creditor to accelerate maturity of a debt upon the
            occurrence of a default deemed immaterial or might decline to
            order a borrower to perform covenants.  Such principles applied by
            a court might include a requirement that the creditor act with
            reasonableness and in good faith.  Furthermore, a court may refuse
            to enforce a covenant where a court deems such covenant to be
            violative of applicable public policy.

      (b)   Certain provisions of the each of the Credit Agreement and the
            Subsidiary Guaranty may be unenforceable in whole or in part under
            the laws of the State of Illinois, but the inclusion of such
            provisions does not affect the validity of the each of the Credit
            Agreement and the Subsidiary Guaranty, and, except as set forth in
            subparagraph (a) above, theeach of the Credit Agreement and
            Subsidiary Guaranty contains adequate provisions for the practical
            realization of the benefits intended thereby.

      (c)   Our opinion expressed above is limited to the law of the State of
            Illinois and the Federal law of the United States, and we do not
            express any opinion herein concerning any other law.

      We understand that copies of this opinion will be delivered to (certain
Banks not listed on Schedule A), and such Banks may rely on this opinion as if
it were addressed to them.

                           Very truly yours,

To each of the Banks parties
  to the Credit Agreement dated
  December 4, 1992, as amended,
  among CBI Industries, Inc., said
  Banks, and Ibis Investments, Inc.
  as Bid Advance Agent

Gentlemen:

      This opinion is furnished to you pursuant to Section 5.4(b) of the
Credit Agreement dated as of December 4, 1992, as amended (the "Credit
Agreement") among CBI Industries, Inc. (the "Company"), the Specified
Subsidiaries party thereto, the Banks parties thereto, and Ibis Investments,
Inc. as Bid Advance Agent for said Banks.  Terms defined in the Credit
Agreement are used herein as therein defined.

      As Senior Vice President and General Counsel to the Company, I have
participated in the preparation, execution, and delivery of the Specified
Subsidiary Agreement and the Notes dated as of                 executed by
[Name of Subsidiary] (the "Applicable Subsidiary").  In that connection I have
examined:

      1.    The Credit Agreement;

      2.    The Specified Subsidiary Agreement; and

      2.    The documents furnished pursuant to Section 5.4 of the Credit
            Agreement.

      In addition, I have reviewed such of the corporate proceedings of the
Company and the Applicable Subsidiary, and have examined such documents,
corporate records, certificates of public officials and of officers of the
Company and the Applicable Subsidiary, agreements, and other instruments as I
have deemed necessary for the purpose of this opinion.  I have assumed the due
execution and delivery, pursuant to due authorization, of the Credit Agreement
by the Banks and the Bid Advance Agent, and the authenticity of all documents
submitted to me as originals and the conformity to the original documents of
all documents submitted to me as certified, conformed, or photostatic copies.

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

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

      1.    The Applicable Subsidiary is a corporation duly incorporated,
            validly existing, and in good standing under the laws of its state
            of incorporation and has the corporate power and authority to
            carry on its business as now being conducted and to own its
            properties.  The Applicable Subsidiary has been duly qualified as
            a foreign corporation for the transaction of business and is in
            good standing under the laws of each other jurisdiction in the
            United States in which the failure to so qualify could reasonably
            be expected to have a Material Adverse Effect.

      2.    The execution, delivery, and performance by the Applicable
            Subsidiary of the Specified Subsidiary Agreement and its Notes are
            within such Applicable Subsidiary's corporate powers, have been
            duly authorized by all necessary corporate action, and do not (i)
            contravene, or constitute a default under, such Applicable
            Subsidiary's certificate of incorporation or by-laws, or any
            judgment, law, rule, or regulation known to me applicable to the
            Applicable Subsidiary, or any indenture, mortgage, deed of trust,
            or other material agreement or instrument by which the Applicable
            Subsidiary is bound or (ii) result in the creation of any lien,
            charge, or encumbrance upon any of the property or assets of the
            Applicable Subsidiary .  The Specified Subsidiary Agreement and
            the Notes have been duly executed and delivered on behalf of the
            Applicable Subsidiary.

      3.    No authorization, approval, or other action by, and no notice to
            or filing with, any Governmental Authority is required for the due
            execution, delivery, and performance by the Applicable Subsidiary
            of the Specified Subsidiary Agreement and the Notes.

      4.    The Specified Subsidiary Agreement and the applicable Notes are
            valid and legally binding obligations of the Applicable Subsidiary
            enforceable against the Applicable Subsidiary in accordance with
            their respective terms, subject, as to enforcement, to bankruptcy,
            insolvency, reorganization, and other laws of general
            applicability relating to or affecting creditors' rights and to
            general equity principles.

      5.    There is no pending or, to the best of my knowledge, threatened
            action or proceeding against the Applicable Subsidiary before any
            Governmental Authority which purports to affect the legality,
            validity, or enforceability of the Credit Agreement, the Specified
            Subsidiary Agreement, or the applicable Notes. 

                           Very truly yours,



                           Charles O. Ziemer

obligations under Article XI of the Credit Agreement, being herein
collectively called the "Liabilities"); provided, however, that the liability
of each of the undersigned hereunder shall be limited to the maximum amount of
the Liabilities which such undersigned may guaranty without violating any
fraudulent conveyance or fraudulent transfer law (plus all costs and expenses
paid or incurred by any Bank in enforcing this Guaranty against such
undersigned).

      This Guaranty shall in all respects be a continuing, absolute and
unconditional guaranty, and shall remain in full force and effect
(notwithstanding, without limitation, the dissolution of any of the
undersigned or that at any time or from time to time no Liabilities are
outstanding) until all Commitments (as defined in the Credit Agreement) have
terminated and all Liabilities have been finally paid in full.

      The undersigned further agree that if at any time all or any part of any
payment theretofore applied by any Bank to any of the Liabilities is or must
be rescinded or returned by such Bank for any reason whatsoever (including,
without limitation, the insolvency, bankruptcy or reorganization of the
Company, any Specified Subsidiary (as defined in the Credit Agreement) or any
of the undersigned), such Liabilities shall, for the purposes of this
Guaranty, to the extent that such payment is or must be rescinded or returned,
be deemed to have continued in existence, notwithstanding such application by
such Bank, and this Guaranty shall continue to be effective or be reinstated,
as the case may be, as to such Liabilities, all as though such application by
such Bank had not been made.

      Any Bank may, from time to time, at its sole discretion and without
notice to the undersigned (or any of them), take any or all of the following
actions without affecting the rights of the Banks or the obligations of the
undersigned hereunder:  (a) retain or obtain a security interest in any
property to secure any of the Liabilities or any obligation hereunder, (b)
retain or obtain the primary or secondary obligation of any obligor or
obligors, in addition to the undersigned, with respect to any of the
Liabilities, (c) extend or renew any of the Liabilities for one or more
periods (whether or not longer than the original period), alter or exchange
any of the Liabilities, or release or compromise any obligation of any of the
undersigned hereunder or any obligation of any nature of any other obligor
with respect to any of the Liabilities, (d) release its security interest in,
or surrender, release or permit any substitution or exchange for, all or any
part of any property securing any of the Liabilities or any obligation
hereunder, or extend or renew for one or more periods (whether or not longer
than the original period) or release, compromise, alter or exchange any
obligations of any nature of any obligor with respect to any such property,
and (e) resort to the undersigned (or any of them) for payment of any of the
Liabilities when due, whether or not such Bank shall have resorted to any
property securing any of the Liabilities or any obligation hereunder or shall
have proceeded against any other of the undersigned or any other obligor
primarily or secondarily obligated with respect to any of the Liabilities.

      Any amounts received by any Bank from whatever source on account of the
Liabilities may be applied by it toward the payment of the Liabilities; and,
notwithstanding any payments made by or for the account of any of the
undersigned pursuant to this Guaranty, the undersigned shall not be subrogated
to any rights of any Bank until such time as this Guaranty shall have been
discontinued as to all of the undersigned and the Banks shall have received
payment of the full amount of all liabilities of all of the undersigned
hereunder.

      The undersigned hereby expressly waive:  (a) notice of the acceptance by
any Bank of this Guaranty, (b) notice of the existence or creation or non-
payment of all or any of the Liabilities, (c) presentment, demand, notice of
dishonor, protest, and all other notices whatsoever, and (d) all diligence in
collection or protection of or realization upon any Liabilities or any
security for or guaranty of any Liabilities.

      Each of the undersigned further agrees to pay all reasonable expenses
(including reasonable attorneys' fees and legal expenses) paid or incurred by
any Bank in endeavoring to collect the Liabilities of such undersigned, or any
part thereof, and in enforcing this Guaranty against such undersigned.

      Subject to the provisions of the Credit Agreement, any Bank may from
time to time, without notice to the undersigned (or any of them), assign or
transfer any or all of the Liabilities or any interest therein; and,
notwithstanding any such assignment or transfer or any subsequent assignment
or transfer thereof, such Liabilities shall be and remain Liabilities for the
purposes of this Guaranty, and each and every immediate and successive
assignee or tranferee of any of the Liabilities or of any interest therein
shall, to the extent of the interest of such assignee or transferee in the
Liabilities, be entitled to the benefits of this Guaranty to the same extent
as if such assignee or transferee were a Bank.

      No delay on the part of any Bank in the exercise of any right or remedy
shall operate as a waiver thereof, and no single or partial exercise by any
Bank of any right or remedy shall preclude other or further exercise thereof
or the exercise of any other right or remedy; nor shall any modification or
waiver of any provision of this Guaranty be binding upon the Banks except as
expressly set forth in a writing duly signed and delivered on behalf of the
Banks.  No action of any Bank permitted hereunder shall in any way affect or
impair the rights of any Bank or the obligations of the undersigned under this
Guaranty.

      This Guaranty shall be binding upon the undersigned and the successors
and assigns of the undersigned; and to the extent that the Company or any of
the undersigned is either a partnership or a corporation, all references
herein to the Company and to the undersigned, respectively, shall be deemed to
include any successor or successors, whether immediate or remote, to such
partnership or corporation.  The term "undersigned" as used herein shall mean
all parties executing this Guaranty and each of them, and all such parties
shall be jointly and severally obligated hereunder.

      This Guaranty has been delivered at Chicago, Illinois, and shall be
construed in accordance with and governed by the internal laws of the State of
Illinois.  Wherever possible each provision of this Guaranty shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Guaranty shall be prohibited by or invalid under
such law, such provision shall be ineffective to the extent of such
prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Guaranty.

      This Guaranty may be executed in any number of counterparts and by the
different parties hereto on separate counterparts, and each such counterpart
shall be deemed to be an original but all such counterparts shall together
constitute one and the same Guaranty.  At any time after the date of this
Guaranty, one or more additional persons or entities may become parties hereto
by executing and delivering to the Banks counterparts of this Guaranty. 
Immediately upon such execution and delivery (and without any further action),
each such additional person or entity will become a party to, and will be
bound by all of the terms of, this Guaranty.

      ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER OR IN CONNECTION
WITH THIS GUARANTY, SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE COURTS
OF THE STATE OF ILLINOIS OR IN THE UNITED STATES DISTRICT COURT FOR THE
NORTHERN DISTRICT OF ILLINOIS; PROVIDED, HOWEVER, THAT ANY SUIT SEEKING
ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT THE
OPTION OF ANY BANK, IN THE COURTS OF ANY JURISDICTION WHERE SUCH COLLATERAL OR
OTHER PROPERTY MAY BE FOUND.  EACH OF THE UNDERSIGNED HEREBY EXPRESSLY AND
IRREVOCABLY SUBMITS TO THE JURISDICTION OF THE COURTS OF THE STATE OF ILLINOIS
AND OF THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS
FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE.  EACH OF THE
UNDERSIGNED FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY
REGISTERED MAIL, POSTAGE PREPAID, TO THE ADDRESS SET FORTH OPPOSITE ITS
SIGNATURE HERETO (OR SUCH OTHER ADDRESS AS IT SHALL HAVE SPECIFIED IN WRITING
TO THE BANKS AS ITS ADDRESS FOR NOTICES HEREUNDER) OR BY PERSONAL SERVICE
WITHIN OR WITHOUT THE STATE OF ILLINOIS.  EACH OF THE UNDERSIGNED HEREBY
EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY
OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY
SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT
ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.  TO THE EXTENT
THAT ANY OF THE UNDERSIGNED HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM
JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE
OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR
OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, SUCH UNDERSIGNED HEREBY
IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS
GUARANTY.

      IN WITNESS WHEREOF, this Guaranty has been duly executed and delivered
as of the day and year first above written.

                         Contingency Agent Provisions

      1.    General.  Each Bank hereby irrevocably authorizes the Contingency
Agent to take such action on its behalf under the provisions of this Agreement
and to exercise such powers and perform such duties as are expressly delegated
to the Contingency Agent by the terms of this Agreement, together with such
other powers as are reasonably incidental thereto.  Notwithstanding any
provision to the contrary elsewhere in this Agreement, the Contingency Agent
shall not have any duties or responsibilities except those expressly set forth
herein, or any fiduciary relationship with any Bank, and no implied covenants,
functions, responsibilities, duties, obligations, or liabilities shall be read
into this Agreement or otherwise exist against the Contingency Agent.

      2.    Delegation of Duties.  The Contingency Agent may execute any of
its duties under this Agreement by or through agents or attorneys-in-fact and
shall be entitled to the advice of counsel concerning all matters pertaining
to such duties.  The Contingency Agent shall not be responsible for the
negligence or misconduct of any agents or attorneys-in-fact selected by it
with reasonable care.

      3.    Exculpatory Provisions.  Neither the Contingency Agent nor any of
its officers, directors, employees, agents, attorneys-in-fact, or affiliates
shall be (i) liable to any Bank for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement (except
for its or such Person's own gross negligence or willful misconduct), or (ii)
responsible in any manner to any of the Banks for any recitals, statements,
representations, or warranties made by the Company, any Specified Subsidiary,
or any officer of any thereof contained in this Agreement or in any
certificate, report, statement, or other document referred to or provided for
in, or received by the Contingency Agent under or in connection with, this
Agreement or the value, validity, effectiveness, genuineness, enforceability,
or sufficiency of this Agreement or for any failure of the Company or any
Specified Subsidiary to perform its obligations hereunder.  The Contingency
Agent shall not be under any obligation to any Bank to ascertain or to inquire
as to the observance or performance of any of the agreements contained in this
Agreement, or to inspect the properties, books, or records of the Company or
any Specified Subsidiary.

      4.    Reliance by Contingency Agent.  The Contingency Agent shall be
entitled to rely, and shall be fully protected in relying, upon any writing,
resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, telecopy, telex, or teletype message, statement, order, or other
document or conversation believed by it to be genuine and correct and to have
been signed, sent, or made by the proper Person or Persons, and upon advice
and statements of legal counsel (including, without limitation, counsel to the
Company or any Specified Subsidiary), independent accountants, and other
experts selected by the Contingency Agent.  The Contingency Agent shall be
fully justified in failing or refusing to take any discretionary action under
this Agreement unless it shall first receive such advice or concurrence of the
Banks as it deems appropriate or it shall first be indemnified to its
satisfaction by the Banks against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action.

      5.    Non-Reliance on Contingency Agent and Other Banks.  Each Bank
expressly acknowledges that neither the Contingency Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact, or affiliates has
made any representations or warranties to it and that no act by the
Contingency Agent hereinafter taken, including any individual review of the
affairs of the Company or any Specified Subsidiary, shall be deemed to
constitute any representation or warranty by the Contingency Agent to any
Bank.  Each Bank represents to the Contingency Agent that it has,
independently and without reliance upon the Contingency Agent or any other
Bank, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial, and other condition and credit-worthiness of
the Company and its Subsidiaries and made its own decision to make its loans
hereunder and enter into this Agreement.  Each Bank also represents that it
will, independently and without reliance upon the Contingency Agent or any
other Bank, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals,
and decisions in taking or not taking action under this Agreement, and to make
such investigation as it deems necessary to inform itself as to the business,
operations, property, financial, and other condition and credit-worthiness of
the Company and its Subsidiaries.  Except for notices expressly required to be
furnished to the Banks by the Contingency Agent hereunder, the Contingency
Agent shall not have any duty or responsibility to provide any Bank with any
credit or other information concerning the business, operations, property,
financial, and other condition and credit-worthiness of the Company or any
Subsidiary.  Except for notices expressly required to be furnished to the
Banks by the Contingency Agent hereunder, the Contingency Agent shall not have
any duty or responsibility to provide any Bank with any credit or other
information concerning the business, operations, property, financial, and
other condition or credit-worthiness of the Company or any Subsidiary,
including information of a Default or Event of Default, which may come into
the possession of the Contingency Agent or any of its officers, directors,
employees, agents, attorneys-in-fact, or affiliates.

      6.    Indemnification.  The Banks agree to indemnify the Contingency
Agent in its capacity as such (to the extent not reimbursed by the Company or
any Subsidiary and without limiting the obligation of the Company or any
Subsidiary to do so), ratably according to their respective Commitments in
effect (or, if the Commitments are no longer in effect, according to the
respective unpaid principal amount of the Advances) on the date of incurrence
by the Contingency Agent of an indemnifiable cost hereunder, from and against
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses, or disbursements of any kind whatsoever,
which may at any time (including without limitation at any time following the
payments of the Advances) be imposed on, incurred by, or asserted against the
Contingency Agent in any way relating to or arising out of this Agreement, or
any documents contemplated by or referred to herein or the transactions
contemplated hereby or any action taken or omitted by the Contingency Agent
under or in connection with any of the foregoing; provided that no Bank shall
be liable for the payment of any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses, or
disbursements resulting solely from the Contingency Agent's gross negligence
or willful misconduct.  The agreements in this Section shall survive the
payment of the Advances and all other amounts payable hereunder.

      7.    Contingency Agent in Its Individual Capacity.  The Contingency
Agent and its affiliates may make loans to, accept deposits from, and
generally engage in any kind of business with the Company and its Subsidiaries
as though the Contingency Agent were not the Contingency Agent hereunder. 
With respect to its Advances made by it, the Contingency Agent shall have the
same rights and powers under this Agreement as any Bank and may exercise the
same as though it were not the Contingency Agent, and the terms "Bank" and
"Banks" shall include the Contingency Agent in its individual capacity.

      8.    Successor Contingency Agent.  The Contingency Agent may resign as
Contingency Agent upon 30 days' notice thereof to the Company and the Banks. 
The Contingency Agent shall resign as Contingency Agent upon 30 days' notice
from the Majority Banks to the Contingency Agent requesting such resignation. 
If the Contingency Agent shall or shall be notified to resign as Contingency
Agent under this Agreement, then the Majority Banks shall appoint from among
the Banks a successor agent for the Banks, which successor agent shall be
reasonably acceptable to the Company, whereupon such successor agent shall
succeed to the rights, power, and duties of the Contingency Agent, and the
term "Contingency Agent" shall mean such successor agent effective upon its
appointment, and the former Contingency Agent's rights, powers, and duties as
Contingency Agent shall be terminated, without any other or further act or
deed on the part of such former Contingency Agent or any of the parties to
this Agreement.  After any retiring Contingency Agent's resignation hereunder
as Contingency Agent, the provisions of this Section shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Contingency Agent under this Agreement.  Anything contained in this Agreement
to the contrary notwithstanding, if a successor agent is appointed as a result
of the resignation of the Contingency Agent pursuant to the second sentence of
this Section, then the costs incurred by such successor agent (including the
reasonable fees of counsel to such successor agent) in connection with its
preparation to perform its obligations hereunder in such capacity shall be
paid by those Banks which shall have delivered the applicable resignation
notice to the Contingency Agent and the Company.
