        For the purposes of calculating the ratio of earnings to fixed
   charges, earnings consist of income before income taxes, adjusted for
   fixed charges.  Fixed charges consist of interest, whether expensed or
   capitalized, amortization of debt expense and one-third of minimum
   rental payments under operating leases (estimated by management to be
   the interest factor of such rentals).  In 1993, earnings, as defined,
   were inadequate to cover fixed charges by $1,917,000.


                         DESCRIPTION OF COMMON STOCK

   GENERAL

        The following is a description of certain terms of the Common
   Stock.  This description does not purport to be complete and is
   subject to and qualified in its entirety by reference to the
   provisions of the Company's Restated Certificate of Incorporation
   relating to the Common Stock.

        The authorized common stock of the Company consists of 80,000,000
   shares of Common Stock, $1.00 par value per share.  As of March 31,
   1998, there were 27,688,317 shares of Common Stock outstanding.

        Holders of Common Stock are entitled to one vote for each share
   held on all matters submitted to a vote of stockholders and do not
   have cumulative voting rights.  Holders of a majority of the shares of
   Common Stock entitled to vote in any election of directors may elect
   all of the directors standing for election. Upon the liquidation,
   dissolution or winding up of the Company, the holders of Common Stock
   are entitled to receive ratably the net assets of the Company
   available after the payment of all debts and other liabilities. 
   Holders of Common Stock have no preemptive, subscription, redemption
   or conversion rights.  The outstanding shares of Common Stock are
   fully paid and non-assessable.

        The rights, preferences and privileges of holders of Common Stock
   are subject to, and may be adversely affected by, the rights of the
   holders of shares of any series of preferred stock which the Company
   may designate and issue in the future.


                                      7<PAGE>





   DIVIDENDS

        Holders of Common Stock are entitled to receive ratably such
   dividends, if any, as may be declared by the Board of Directors
   applicable to Common Stock out of funds legally available therefor. 
   Declaration of future dividends by the Board of Directors will depend
   on general business conditions encountered by the Company, earnings,
   financial condition and capital requirements of the Company and such
   other factors as the Board of Directors may deem relevant.

        Certain of the Company's debt agreements contain provisions
   restricting the payment of dividends or repurchase of its shares. 
   Under the most restrictive of these provisions, the Company may not
   pay dividends (other than stock dividends) or acquire its capital
   stock if after giving effect thereto the aggregate amounts paid on or
   after June 1, 1995 exceed the sum of (i) $20,000,000 plus (ii) 50% of
   consolidated net income of the Company after June 1, 1994.  Certain
   restrictions on the declaration or payment of dividends on Common
   Stock and the repurchase of Common Stock shares by the Company apply
   if there are any shares of preferred stock outstanding.

   CERTAIN CHARTER AND BY-LAW PROVISIONS

        GENERAL.  The Company has implemented certain measures designed
   to enhance the Board of Directors' ability to protect stockholders
   against, among other things, unsolicited attempts to acquire a
   significant interest in the Company or to influence the Company's
   management (whether through open market purchases, tender offers or
   otherwise) that do not offer an adequate price to all stockholders or
   that the Board of Directors otherwise considers not in the best
   interests of the Company and its stockholders.

        Certain provisions in the Restated Certificate of Incorporation
   of the Company may have a significant impact on the stockholders'
   ability to change the composition of the incumbent Board of Directors
   or the ability of a substantial holder of the Common Stock to acquire
   control of, or to remove, the incumbent Board of Directors, and might
   discourage certain types of transactions that involve an actual or
   threatened change of control of the Company.

        The provisions of the Restated Certificate of Incorporation are
   intended to encourage persons seeking to acquire control of the
   Company to initiate such an acquisition through arm's-length
   negotiations with the Company's management and Board of Directors. 
   These provisions could have the effect of discouraging a third party
   from making a tender offer to or otherwise attempting to obtain
   control of the Company, even though such an attempt might be
   beneficial to the Company and its stockholders.  At the same time,
   these provisions help ensure that the Board of Directors, if
   confronted by an unsolicited proposal from a third party who has
   recently acquired a block of Common Stock, will have sufficient time
   to review the proposal and alternatives to it and to seek better

                                      8<PAGE>





   proposals for its stockholders, employees, suppliers, customers and
   others.  These provisions are discussed below.

        INDEMNIFICATION.  Pursuant to the provisions of the Delaware
   General Corporation Law (the "Delaware GCL"), the Company has adopted
   provisions in its Restated Certificate of Incorporation which require
   the Company to indemnify its officers and directors to the fullest
   extent permitted by law, and eliminate the personal liability of its
   directors to the Company or its stockholders for monetary damages for
   breach of their duty of due care except (i) for any breach of the duty
   of loyalty; (ii) for acts or omissions not in good faith or which
   involve intentional misconduct or knowing violations of law; (iii) for
   liability under Section 174 of the Delaware GCL (relating to certain
   unlawful dividends, stock repurchases or stock redemptions); or (iv)
   for any transaction from which the director derived any improper
   personal benefit.  These provisions do not eliminate a director's duty
   of care.  Moreover, the provisions do not apply to claims against a
   director for violation of certain laws, including Federal securities
   laws.  The Company believes that these provisions assist the Company
   in attracting and retaining qualified individuals to serve as
   directors and officers.

        PREFERRED STOCK.  The Company's Restated Certificate of
   Incorporation includes a provision which allows the Board of
   Directors, without stockholder approval, to issue up to 250,000 shares
   of preferred stock with voting, liquidation and conversion rights that
   could be superior to and adversely affect the voting power of holders
   of Common Stock.  The issuance of preferred stock could have the
   effect of delaying, deferring or preventing a change in control of the
   Company.

        CLASSIFIED BOARD OF DIRECTORS.  The Company's Restated
   Certificate of Incorporation provides that the Board of Directors of
   the Company shall be divided into three classes of directors serving
   staggered three-year terms.  The classification of directors has the
   effect of making it more difficult for stockholders to change the
   composition of the Board of Directors in a relatively short period of
   time.

        VOTING RESTRICTION ON CERTAIN BUSINESS COMBINATIONS.  An
   affirmative vote of the holders of at least 80% of the outstanding
   shares of capital stock of the Company entitled to vote generally in
   the election of directors is required with respect to the adoption or
   approval of certain business combinations, including mergers,
   consolidations, asset and securities sales, plans of liquidation or
   dissolution and certain reclassifications, involving any related party
   (as defined below).

        A related party is defined in the Company's Restated Certificate
   of Incorporation to mean the beneficial owner, directly or indirectly,
   of not less than 10% of the voting stock of the Company.


                                      9<PAGE>





        The 80% affirmative voting requirement is not applicable to
   business combinations approved by (i) a majority of the Board of
   Directors of the Company prior to the acquisition by the related party
   of 10% of the then outstanding voting stock or (ii) a majority of
   those members of the Board of Directors who are not related party
   directors.

        SPECIAL STOCKHOLDERS' MEETINGS.  The Restated Certificate of
   Incorporation and By-Laws allow only the Chairman of the Board of
   Directors or majority of the Board of Directors then in office to call
   a special meeting of the stockholders.

        NO ACTION BY STOCKHOLDER CONSENT.  The Company's Restated
   Certificate of Incorporation prohibits action that is required or
   permitted to be taken at any annual or special meeting of stockholders
   of the Company from being taken by the written consent of stockholders
   without a meeting.

        SUPERMAJORITY VOTING.  The classified Board, special meeting and
   stockholder consent, as well as certain other provisions, of the
   Restated Certificate of Incorporation may be altered, amended, or
   repealed only if the holders of 80% or more of the outstanding shares
   of voting stock entitled to vote in the election of directors vote in
   favor of such action.  The By-Laws of the Company may be amended,
   altered, changed or replaced by the affirmative vote of the holders of
   at least 80% or more of the outstanding shares of voting stock
   entitled to vote in the election of directors or by a majority of
   Board of Directors then in office.

   DELAWARE ANTI-TAKEOVER LAW

        The Company is a Delaware corporation that is subject to Section
   203 of the Delaware GCL ("Section 203").  Under Section 203 certain
   "business combinations" between a Delaware corporation, whose stock
   generally is publicly traded or held of record by more than 2,000
   stockholders, and an "interested stockholder" are prohibited for a
   three-year period following the date that such stockholder became an
   interested stockholder, unless (i) the corporation has elected in its
   certificate of incorporation not to be governed by Section 203 (the
   Company has not made such election), (ii) the business combination was
   approved by the board of directors of the corporation before the other
   party to the business combination became an interested stockholder,
   (iii) upon consummation of the transaction that made it an interested
   stockholder, the interested stockholder owned at least 85% of the
   voting stock of the corporation outstanding at the commencement of the
   transaction (excluding voting stock owned by directors who are also
   officers or held in employee benefit plans in which the employees do
   not have a confidential right to tender or vote stock held by the
   plan) or (iv) the business combination is approved by the board of
   directors of the corporation and ratified by two-thirds of the voting
   stock which the interested stockholder did not own.  The three-year
   prohibition also does not apply to certain business combinations

                                     10<PAGE>





   proposed by an interested stockholder following the announcement or
   notification of certain extraordinary transactions involving the
   corporation and a person who had not been an interested stockholder
   during the previous three years or who became an interested
   stockholder with the approval of a majority of the corporation's
   directors.  The term "business combination" is defined generally to
   include mergers or consolidations between a Delaware corporation and
   an interested stockholder, transactions with an interested stockholder
   involving the assets or stock of the corporation or its majority-owned
   subsidiaries, and transactions which increase an interested
   stockholder's percentage ownership of stock.  The term "interested
   stockholder" is defined generally as those stockholders who become
   beneficial owners of 15% or more of a Delaware corporation's voting
   stock, together with the affiliates or associates of that stockholder.

   RIGHTS AGREEMENT

        Pursuant to a Rights Agreement adopted in 1997, each outstanding
   share of the Company's Common Stock carries with it a right to
   purchase one additional share at a price of $83.33 (subject to
   anti-dilution adjustments).  The rights become exercisable (and
   separate from the shares) when certain specified events occur,
   including the acquisition of 15% or more of the Common Stock by a
   person or group (an "Acquiring Person") or the commencement of a
   tender or exchange offer for 15% or more of the Common Stock.  The
   rights replace Common Stock purchase rights initially distributed to
   holders of the Company's Common Stock in 1987 and which expired by
   their own terms in 1997.

        In the event that an Acquiring Person acquires 15% or more of the
   Common Stock, or if the Company is the surviving corporation in a
   merger involving an Acquiring Person, or if the Acquiring Person
   engages in certain types of self-dealing transactions, each right
   entitles the holder to purchase for the then current exercise price
   that number of shares of Common Stock having a market value of two
   times the exercise price, subject to certain exceptions.  Similarly,
   if the Company is acquired in a merger or other business combination
   or 50% of more of its assets or earning power is sold, each right
   entitles the holder to purchase at the then current exercise price
   that number of shares of common stock of the surviving corporation
   having a market value of two times the exercise price.  The rights,
   which do not entitle the holder thereof to vote or to receive
   dividends, expire on August 6, 2007 and may be redeemed by the Company
   for $.01 per right under certain circumstances.


                       DESCRIPTION OF PREFERRED STOCK

   GENERAL

        The following is a description of certain general terms and
   provisions applicable to Preferred Stock as a class.  The particular

                                     11<PAGE>





   terms of any series of Preferred Stock will be described in the
   applicable Prospectus Supplement.  This description does not purport
   to be complete and is subject to and qualified in its entirety by the
   provisions of the Company's Restated Certificate of Incorporation and
   a certificate of designation relating to each series of Preferred
   Stock (each, a "Certificate of Designation"), which will be filed as
   an exhibit to or incorporated by reference in the Registration
   Statement of which this Prospectus is a part at or prior to the time
   of issuance of such series of Preferred Stock.  

        The Company's Restated Certificate of Incorporation authorizes
   the issuance of 250,000 shares of Preferred Stock, par value $1.00 per
   share.  No shares of Preferred Stock are currently outstanding.

        Under the Company's Restated Certificate of Incorporation, the
   Preferred Stock may be issued from time to time in one or more series
   with such serial designation and (i) may have such voting powers, full
   or limited, or may be without voting powers; (ii) may be subject to
   redemption at such time or times and such prices; (iii) may be
   entitled to receive dividends (which may be cumulative or
   noncumulative) at such rates, on such conditions, and at such times,
   and payable in preference to, or in such relation to, the dividends
   payable on any other class or classes of stock; (iv) may be entitled
   to such rights upon the dissolution of, or upon any distribution of
   the assets of, the Company; (v) may be made convertible into, or
   exchangeable for, shares of any other class or classes of stock of the
   Company at such price or prices or at such other rates of exchange and
   with such adjustments; and (vi) shall have such other preferences and
   relative, participating, optional or other special rights, and
   qualifications, limitations or restrictions thereof, all as stated in
   a Certificate of Designation adopted by the Board of Directors of the
   Company.

        The Prospectus Supplement relating to the particular Preferred
   Stock offered thereby (the "Offered Preferred Stock") will describe
   the following terms of the Offered Preferred Stock:  (i) the
   designation and stated value per share of the Offered Preferred Stock
   and the number of shares offered; (ii) the amount of liquidation
   preference per share of the Offered Preferred Stock; (iii) the initial
   public offering price at which the Offered Preferred Stock will be
   issued; (iv) the dividend rate (or method of calculation), the dates
   on which dividends shall be payable and the dates from which dividends
   shall commence to cumulate, if any; (v) any redemption or sinking fund
   provisions; (vi) any conversion or exchange rights; (vii) whether the
   Company has elected to offer Depositary Shares as described below
   under "Description of Depositary Shares"; and (viii) any additional
   voting, dividend, liquidation, redemption, sinking fund and other
   rights, preferences, privileges, limitations and restrictions.

        The Preferred Stock will have the dividend, liquidation,
   redemption and voting rights set forth below unless otherwise provided
   in the applicable Prospectus Supplement.

                                     12<PAGE>





        The Preferred Stock will be, upon issuance against full payment
   therefor, fully paid and nonassessable.  The holders of Preferred
   Stock will not have any preemptive rights.  The applicable Prospectus
   Supplement will contain a description of certain United States Federal
   income tax consequences relating to the purchase and ownership of the
   Offered Preferred Stock.

   RANK

        With respect to dividend rights and rights upon the liquidation,
   dissolution or winding up of the Company, each share of Preferred
   Stock will rank on a parity with each other share of Preferred Stock,
   irrespective of series, and will rank prior to the Common Stock and
   any other class or series of capital stock of the Company hereafter
   authorized over which the Preferred Stock has preference or priority
   in the payment of dividends or in the distribution of assets on any
   liquidation, dissolution or winding up of the Company.

        The Preferred Stock will be junior to all outstanding debt of the
   Company.  Each series of Preferred Stock will be subject to creation
   of preferred stock ranking senior to, on a parity with or junior to
   such Preferred Stock to the extent not expressly prohibited by the
   Company's Restated Certificate of Incorporation.

   DIVIDENDS

        Holders of shares of Preferred Stock will be entitled to receive,
   when, as and if declared by the Board of Directors out of funds of the
   Company legally available for payment, cash dividends, payable at such
   dates and at such rates per share per annum as set forth in the
   applicable Prospectus Supplement.  Such rate may be fixed or variable
   or both.  Each declared dividend will be payable to holders of record
   as they appear at the close of business on the stock books of the
   Company (or, if applicable, on the records of the Depositary (as
   hereinafter defined) referred to below under "Description of
   Depositary Shares") on such record dates, not more than 60 calendar
   days preceding the payment dates thereof, as are determined by the
   Board of Directors (each of such dates, a "Record Date").

        Such dividends may be cumulative or noncumulative, as provided in
   the applicable Prospectus Supplement.  If dividends on a series of
   Preferred Stock are noncumulative and if the Board of Directors fails
   to declare a dividend in respect of a dividend period with respect to
   such series, then holders of such Preferred Stock will have no right
   to receive a dividend in respect of such dividend period, and the
   Company will have no obligation to pay the dividend for such period,
   whether or not dividends are declared payable on any future dividend
   payment date.

        No full dividend will be declared or paid or set apart for
   payment on the Preferred Stock of any series for any dividend period
   unless full cumulative dividends have been or contemporaneously are

                                     13<PAGE>





   declared and paid or declared and a sum sufficient for the payment
   thereof set apart for such payment on all the outstanding shares of
   Preferred Stock for all dividend periods terminating on or prior to
   the end of such dividend period.  When dividends are not paid in full
   as aforesaid on all shares of Preferred Stock, as the case may be, any
   dividend payments (including accruals, if any) on the Preferred Stock
   will be paid to the holders of the shares of the Preferred Stock
   ratably in proportion to the respective sums which such holders would
   receive if all dividends thereon accrued to the date of payment were
   declared and paid in full.  Accruals of dividends will not bear
   interest.  So long as any shares of Preferred Stock are outstanding,
   in no event will any dividends, whatsoever, whether in cash or
   property, be paid or declared, nor will any distribution be made, on
   any class of stock ranking subordinate to the Preferred Stock nor will
   any shares of stock ranking subordinate to the Preferred Stock be
   purchased, redeemed or otherwise acquired for consideration by the
   Company or any subsidiary of the Company, unless all dividends on the
   Preferred Stock for all past quarterly dividend periods will have been
   paid or declared and a sum sufficient for the payment thereof set
   apart.  The foregoing provisions will not, however, apply to a
   dividend payable solely in shares of any stock ranking subordinate to
   the Preferred Stock or to the acquisition of shares of any stock
   ranking subordinate to the Preferred Stock in exchange solely for
   shares of any other stock ranking subordinate to the Preferred Stock.

   LIQUIDATION

        In the event of a liquidation, dissolution or winding up of the
   Company, the holders of the Offered Preferred Stock will be entitled,
   subject to the rights of creditors, but before any distribution or
   payment to the holders of Common Stock or any other security ranking
   junior to the Offered Preferred Stock, to receive an amount per share
   determined by the Board of Directors and set forth in the applicable
   Prospectus Supplement plus accrued and unpaid dividends to the
   distribution or payment date (whether or not earned or declared). 
   However, neither the merger, nor the sale, lease or conveyance of all
   or substantially all of the assets of the Company will be deemed a
   liquidation, dissolution or winding up of the Company for purposes of
   this provision.  In the event that the assets available for
   distribution with respect to the Preferred Stock are not sufficient to
   satisfy the full liquidation rights of all the outstanding Preferred
   Stock, then such assets will be distributed to the holders of such
   Preferred Stock ratably in proportion to the full amounts to which
   they would otherwise be respectively entitled.  After payment of the
   full amount of the liquidation preference, the holders of Preferred
   Stock will not be entitled to any further participation in any
   distribution of assets by the Company.

   VOTING RIGHTS

        Except as required by law, the Preferred Stock will not be
   entitled to any voting rights unless provided for in the applicable

                                     14<PAGE>





   Certificate of Designations and set forth in the applicable Prospectus
   Supplement.  As more fully described under "Description of Depositary
   Shares" below, if the Company elects to issue Depositary Shares, each
   representing a fraction of a share of a series of the Preferred Stock,
   each such Depositary Share will, in effect, be entitled to such
   fraction of a vote per Depositary Share.

   NO OTHER RIGHTS

        The shares of a series of Preferred Stock will not have any
   preferences, voting powers or relative, participating, optional or
   other special rights except as set forth above or in the applicable
   Prospectus Supplement, the Restated Certificate of Incorporation and
   the applicable Certificate of Designation or as otherwise required by
   law.

   TRANSFER AGENT AND REGISTRAR

        The transfer agent and registrar for the Offered Preferred Stock
   will be described in the applicable Prospectus Supplement.


                      DESCRIPTION OF DEPOSITARY SHARES

        The following is a description of certain general terms and
   provisions of the Depositary Shares.  The particular terms of any
   series of Depositary Shares will be described in the applicable
   Prospectus Supplement.  If so indicated in a Prospectus Supplement,
   the terms of any such series may differ from the terms set forth
   below.  The summary of terms of the Deposit Agreement (as defined
   below) and of the Depositary Shares and Depositary Receipts (as
   defined below) contained in this Prospectus does not purport to be
   complete and is subject to, and qualified in its entirety by,
   reference to the forms of the Deposit Agreement and Depositary
   Receipts which will be filed with the Commission at or prior to the
   time of the offering of such Depositary Shares.

   GENERAL

        The Company may, at its option, elect to offer fractional
   interests in shares of Preferred Stock rather than shares of Preferred
   Stock.  In the event such option is exercised, the Company will
   provide for the issuance by a Depositary to the public of receipts for
   Depositary Shares ("Depositary Receipts"), each of which will
   represent a fractional interest.

        The shares of any series of the Preferred Stock underlying the
   Depositary Shares will be deposited under a separate Deposit Agreement
   (the "Deposit Agreement") between the Company and a bank or trust
   company selected by the Company having its principal office in the
   United States and having a combined capital and surplus of at least
   $50,000,000 (the "Depositary").  The Prospectus Supplement relating to

                                     15<PAGE>





   a series of Depositary Shares will set forth the name and address of
   the Depositary.  Subject to the terms of the Deposit Agreement, each
   owner of a Depositary Share will be entitled, in proportion to the
   applicable fractional interest in a share of Preferred Stock
   underlying such Depositary Shares, to all the rights and preferences
   of the Preferred Stock underlying such Depositary Share (including
   dividend, voting, redemption, conversion and liquidation rights).

        The Depositary Shares will be evidenced by Depositary Receipts
   issued pursuant to the Deposit Agreement.

        Pending the preparation of definitive engraved Depositary
   Receipts, the Depositary may, upon the written order of the Company,
   issue temporary Depositary Receipts substantially identical to (and
   entitling the holders thereof to all the rights pertaining to) the
   definitive Depositary Receipts but not in definitive form.  Definitive
   Depositary Receipts will be prepared thereafter without unreasonable
   delay, and temporary Depositary Receipts will be exchangeable for
   definitive Depositary Receipts at the Company's expense.

        Upon surrender of Depositary Receipts at the office of the
   Depositary and upon payment of the charges provided in the Deposit
   Agreement and subject to the terms thereof, a holder of Depositary
   Shares is entitled to have the Depositary deliver to such holder the
   whole shares of Preferred Stock underlying the Depositary Shares
   evidenced by the surrendered Depositary Receipts.

   DIVIDENDS AND OTHER DISTRIBUTIONS

        The Depositary will distribute all cash dividends or other cash
   distributions received in respect of the applicable Preferred Stock to
   the record holders of Depositary Shares relating to such Preferred
   Stock in proportion to the numbers of such Depositary Shares owned by
   such holders on the relevant record date.  The Depositary shall
   distribute only such amount, however, as can be distributed without
   attributing to any holder of Depositary Shares a fraction of one cent,
   and any balance not so distributed shall be added to and treated as
   part of the next sum received by the Depositary for distribution to
   record holders of Depositary Shares.

        In the event of a distribution other than in cash, the Depositary
   will distribute property received by it to the record holders of
   Depositary Shares entitled thereto, unless the Depositary determines
   that it is not feasible to make such distribution, in which case the
   Depositary may, with the approval of the Company, sell such property
   and distribute the net proceeds from such sale to such holders.

        The Deposit Agreement will also contain provisions relating to
   the manner in which any subscription or similar rights offered by the
   Company to holders of the Preferred Stock shall be made available to
   holders of Depositary Shares.


                                     16<PAGE>





   REDEMPTION OF DEPOSITARY SHARES

        If a series of the Preferred Stock underlying the Depositary
   Shares is subject to redemption, the Depositary Shares will be
   redeemed from the proceeds received by the Depositary resulting from
   the redemption, in whole or in part, of such series of the Preferred
   Stock held by the Depositary.  The Depositary shall mail notice of
   redemption not less than 30 and not more than 60 days prior to the
   date fixed for redemption to the record holders of the Depositary
   Shares to be so redeemed at their respective addresses appearing in
   the Depositary's books.  The redemption price per Depositary Share
   will be equal to the applicable fraction of the redemption price per
   share payable with respect to such series of the Preferred Stock. 
   Whenever the Company redeems shares of Preferred Stock held by the
   Depositary, the Depositary will redeem as of the same redemption date
   the number of Depositary Shares relating to shares of Preferred Stock
   so redeemed.  If less than all of the Depositary Shares are to be
   redeemed, the Depositary Shares to be redeemed will be selected by lot
   or pro rata as may be determined by the Depositary.

        After the date fixed for redemption, the Depositary Shares so
   called for redemption will no longer be deemed to be outstanding and
   all rights of the holders of the Depositary Shares will cease, except
   the right to receive the moneys payable upon such redemption and any
   money or other property to which the holders of such Depositary Shares
   were entitled upon such redemption upon surrender to the Depositary of
   the Depositary Receipts evidencing such Depositary Shares.

   VOTING THE PREFERRED STOCK

        Upon receipt of notice of any meeting at which the holders of the
   Preferred Stock are entitled to vote, the Depositary will mail the
   information contained in such notice of meeting to the record holders
   of the Depositary Shares relating to such Preferred Stock.  Each
   record holder of such Depositary Shares on the record date (which will
   be the same date as the record date for such Preferred Stock) will be
   entitled to instruct the Depositary as to the exercise of the voting
   rights pertaining to the number of shares of Preferred Stock
   underlying such Depositary Shares in accordance with such
   instructions, and the Company will agree to take all action which may
   be deemed necessary by the Depositary in order to enable the
   Depositary to do so.  The Depositary will abstain from voting shares
   of Preferred Stock to the extent it does not receive specific
   instructions from the holders of Depositary Shares relating to such
   Preferred Stock.

   AMENDMENT AND TERMINATION OF THE DEPOSIT AGREEMENT

        The form of Depositary Receipt evidencing the Depositary Shares
   and any provision of the Deposit Agreement may at any time be amended
   by agreement between the Company and the Depositary.  However, any
   amendment which materially and adversely alters the rights of the

                                     17<PAGE>





   existing holders of Depositary Shares will not be effective unless
   such amendment has been approved by the record holders of at least a
   majority of the Depositary Shares then outstanding.  The Deposit
   Agreement may be terminated by the Company or the Depositary only if
   (i) all outstanding Depositary Shares relating thereto have been
   redeemed or (ii) there has been a final distribution in respect of the
   Preferred Stock of the relevant series in connection with any
   liquidation, dissolution or winding up of the Company and such
   distribution has been distributed to the holders of the related
   Depositary Shares.

   CHARGES OF DEPOSITARY

        The Company will pay all transfer and other taxes and
   governmental charges arising solely from the existence of the
   depositary arrangements.  The Company will pay charges of the
   Depositary in connection with the initial deposit of the Preferred
   Stock and any redemption of the Preferred Stock.  Holders of
   Depositary Shares will pay other transfer and other taxes and
   governmental charges and such other charges as are expressly provided
   in the Deposit Agreement to be for their accounts.

   MISCELLANEOUS

        The Depositary will forward to the holders of Depositary Shares
   all reports and communications from the Company which are delivered to
   the Depositary and which the Company is required to furnish to the
   holders of the applicable Preferred Stock.

        Neither the Depositary nor the Company will be liable if it is
   prevented or delayed by law or any circumstance beyond its control in
   performing its obligations under the Deposit Agreement.  The
   obligations of the Company and the Depositary under the Deposit
   Agreement will be limited to performance in good faith of their duties
   thereunder and they will not be obligated to prosecute or defend any
   legal proceeding in respect of any Depositary Shares or Preferred
   Stock unless satisfactory indemnity is furnished.  They may rely upon
   written advice of counsel or accountants, or information provided by
   persons presenting Preferred Stock for deposit, holders of Depositary
   Shares or other persons believed to be competent and on documents
   believed to be genuine.

   RESIGNATION AND REMOVAL OF DEPOSITARY

        The Depositary may resign at any time by delivering to the
   Company notice of its election to do so, and the Company may at any
   time remove the Depositary, any such resignation or removal to take
   effect upon the appointment of a successor Depositary and its
   acceptance of such appointment.  Such successor Depositary must be
   appointed within 60 days after delivery of the notice of resignation
   or removal and must be a bank or trust company having its principal


                                     18<PAGE>





   office in the United States and having a combined capital and surplus
   of at least $50,000,000.


                       DESCRIPTION OF DEBT SECURITIES

        The following description of the Debt Securities sets forth
   certain general terms and provisions of the Debt Securities to which
   any Prospectus Supplement may relate.  The particular terms of the
   Debt Securities offered by any Prospectus Supplement (the "Debt
   Securities") will be described in the Prospectus Supplement relating
   to such Debt Securities.

        Senior Debt Securities ("Senior Debt Securities") are to be
   issued under an indenture dated as of October 15, 1989 between the
   Company and U.S. Bank Trust National Association (formerly known as
   First Trust, National Association, as successor in interest to
   Continental Bank, National Association), as Trustee, as supplemented
   and amended by the First Supplemental Indenture dated as of August 26,
   1991, and the Second Supplemental Indenture dated as of December 10,
   1997 (collectively, the "Indenture").  Subordinated Debt Securities
   ("Subordinated Debt Securities," and together with the Senior Debt
   Securities, "Debt Securities") are to be issued under a new indenture
   or a supplement to the Indenture ("Subordinated Indenture").  A copy
   of the Indenture has been included as an exhibit to the Registration
   Statement.  The following summary of certain provisions of the Debt
   Securities and the Indentures does not purport to be complete and is
   subject to, and is qualified in its entirety by reference to, all the
   provisions of the Indenture, which are incorporated by reference
   herein.  Capitalized terms used herein have the respective meanings
   set forth in the Indenture, and references to sections are to sections
   of the Indenture.

        As of the date of this Prospectus, the Company has outstanding
   under the Indenture $65,000,000 aggregate principal amount of its
   9.50% Notes due November 1, 2001, $50,000,000 aggregate principal
   amount of its 7.25% Notes due October 15, 2003 and $60,000,000
   aggregate principal amount of its 6.875% Notes due December 15, 2007.

   GENERAL

        The Indenture provides that Debt Securities may be issued
   thereunder, without limit as to aggregate principal amount, in one or
   more series by the Company from time to time upon satisfaction of
   certain conditions precedent.  The Company may, from time to time, fix
   the terms of such Debt Securities, including: (i) the title of the
   Debt Securities; (ii) any limit upon the aggregate principal amount of
   the Debt Securities; (iii) the date or dates on which the principal of
   the Debt Securities is payable; (iv) the rate or rates (which may be
   fixed or variable) per annum at which the Debt Securities will bear
   interest, if any, the date or dates from which such interest will
   accrue, the Interest Payment Dates on which such interest will be

                                     19<PAGE>





   payable and the Regular Record Date for the interest payable on any
   Interest Payment Date; (v) the place or places where the principal of
   and premium, if any, and interest on the Debt Securities will be
   payable; (vi) the period or periods within which, the price or prices
   at which and the terms and conditions upon which the Debt Securities
   will, pursuant to any mandatory sinking fund provisions, or may,
   pursuant to any optional sinking fund provisions, be redeemed in whole
   or in part by the Company; (vii) the period or periods within which,
   the price or prices at which and the terms and conditions upon which
   the Debt Securities may be repaid, in whole or in part, at the option
   of the Holder thereof; (viii) if other than denominations of $1,000
   and any integral multiple thereof, the denominations in which the Debt
   Securities may be repaid, in whole or in part, at the option of the
   Holder thereof; (viii) if other than denominations of $1,000 and any
   integral multiple thereof, the denominations in which the Debt
   Securities shall be issuable; (ix) if the Debt Securities are Original
   Issue Document Securities, the portion of principal of such Debt
   Securities that shall be payable upon declaration of acceleration of
   the Maturity thereof; and (x) any other terms of the Debt Securities. 
   Reference is made to the Prospectus Supplement for the terms of the
   Offered Debt Securities being offered thereby. (Section 301)

        The Debt Securities will be issued only in fully registered form
   without coupons, in denominations set forth in the Prospectus
   Supplement.  No service charge will be made for any registration of
   transfer or exchange of such Debt Securities, but the Company may
   require payment of a sum sufficient to cover any tax or other
   governmental charges that may be imposed in connection therewith.

        Any principal, premium and interest will be payable, the transfer
   of the Debt Securities will be registrable, and Debt Securities will
   be exchangeable at the office or agency designated for such purpose in
   the Prospectus Supplement.  Payment of interest may be made at the
   option of the Company by check mailed to the address of the person
   entitled thereto as shown on the Security Register.

        The Debt Securities will be unsecured and will rank pari passu
   with all other unsecured and unsubordinated indebtedness of the
   Company, except Subordinated Debt Securities will, to the extent set
   forth in the Subordinated Indenture, be subordinated in right of
   payment to the prior payment in full of all Senior Debt Securities. 

        Debt Securities may be issued under the Indenture as Original
   Issue Discount Securities to be offered and sold at a substantial
   discount from the principal amount thereof.  If the Offered Debt
   Securities are Original Issue Discount Securities, special federal
   income tax, accounting and other considerations applicable thereto
   will be described in the Prospectus Supplement relating thereto. 
   "Original Issue Discount Security" means any Debt Security which
   provides for an amount less than the principal amount thereof to be
   due and payable upon a declaration of acceleration of Maturity thereof


                                     20<PAGE>





   upon the occurrence of an Event of Default and the continuation
   thereof.

   BOOK-ENTRY DEBT SECURITIES

        The Debt Securities of a series may be issued in whole or in part
   in the form of one or more global securities that will be deposited
   with, or on behalf of, a Depositary ("Global Security Depositary") or
   its nominee identified in the applicable Prospectus Supplement.  In
   such a case, one or more global securities will be issued in a
   denomination or aggregate denominations equal to the portion of the
   aggregate principal amount of outstanding Debt Securities of the
   series to be represented by such global security or securities. 
   Unless and until it is exchanged in whole or in part for Debt
   Securities in registered form, a global security may not be registered
   for transfer or exchange except as a whole by the Global Security
   Depositary for such global security to a nominee of such Depositary or
   by a nominee of such Depositary to such Depositary or another nominee
   of such Depositary or by such Depositary or any nominee to a successor
   Depositary or a nominee of such successor Depositary and except in the
   circumstances described in the applicable Prospectus Supplement.

        The specific terms of the depositary arrangement with respect to
   any portion of a series of Debt Securities to be represented by a
   global security will be described in the applicable Prospectus
   Supplement.  However, the Company expects that the following
   provisions will apply to depositary arrangements.

        Unless otherwise specified in the applicable Prospectus
   Supplement, Debt Securities which are to be represented by a global
   security to be deposited with or on behalf of a Global Security
   Depositary will be represented by a global security registered in the
   name of such Depositary or its nominee.  Upon the issuance of such
   global security, and the deposit of such global security with or on
   behalf of the Global Security Depositary for such global security,
   such Depositary will credit, on its book-entry registration and
   transfer system, the respective principal amounts of the Debt
   Securities represented by such global security to the accounts of
   institutions that have accounts with such Depositary or its nominee
   ("participants").  The accounts to be credited will be designated by
   the underwriters or agents of such Debt Securities or by the Company,
   if such Debt Securities are offered and sold directly by the Company. 
   Ownership of beneficial interests in such global security will be
   limited to participants or persons that may hold interests through
   participants.  Ownership of beneficial interests by participants in
   such global security will be shown on, and the transfer of that
   ownership interest will be effected only through, records maintained
   by the Global Security Depositary or its nominee for such global
   security.  Ownership of beneficial interests in such global security
   by persons that hold through participants will be shown on, and the
   transfer of that ownership interest within such participant will be
   effected only through, records maintained by such participant.  The

                                     21<PAGE>





   laws of some jurisdictions require that certain purchasers of
   securities take physical delivery of such securities in certificated
   form.  The foregoing limitations and such laws may impair the ability
   to transfer beneficial interests in such global securities.

        So long as the Global Security Depositary for a global security,
   or its nominee, is the registered owner of such global security, such
   Depositary or such nominee, as the case may be, will be considered the
   sole owner or Holder of the Debt Securities represented by such global
   security for all purposes under the Indenture.  Unless otherwise
   specified in the applicable Prospectus Supplement, owners of
   beneficial interests in such global security will not be entitled to
   have Debt Securities of the series represented by such global security
   registered in their names, will not receive or be entitled to receive
   physical delivery of Debt Securities of such series in certificated
   form and will not be considered the Holders thereof for any purposes
   under the Indenture.  Accordingly, each person owning a beneficial
   interest in such global security must rely on the procedures of the
   Global Security Depositary and, if such person is not a participant,
   on the procedures of the participant through which such person owns
   its interest, to exercise any rights of a Holder under the Indenture. 
   The Company understands that under existing industry practices, if the
   Company requests any action of holders or an owner of a beneficial
   interest in such global security desires to give any notice or take
   any action a Holder is entitled to give or take under the Indenture,
   the Global Security Depositary would authorize the participants to
   give such notice or take such action, and participants would authorize
   beneficial owners owning through such participants to give such notice
   or take such action or would otherwise act upon the instructions of
   beneficial owners owning through them.

        Principal of and any premium and interest on a global security
   will be payable in the manner described in the applicable Prospectus
   Supplement.

   CERTAIN DEFINITIONS

        The term "Subsidiary" is defined as a corporation a majority of
   the outstanding voting stock of which is owned, directly or
   indirectly, by the Company and/or one or more Subsidiaries of the
   Company.  The term "Restricted Subsidiary" is defined as any
   Subsidiary of the Company except (a) a Subsidiary which neither
   transacts any substantial portion of its business nor regularly
   maintains any substantial portion of its fixed assets within the
   United States and/or Canada, or which is engaged primarily in
   financing the operations of the Company or its Subsidiaries outside
   the United States and Canada and (b) AAR Financial Services Corp. and
   any Subsidiary of the Company created or acquired after the date of
   the Indenture the primary business of which consists of financing
   operations in connection with leasing and conditional sales
   transactions on behalf of the Company and the Subsidiaries of the
   Company, or which is otherwise primarily engaged in the business of a

                                     22<PAGE>





   finance company.  The term "Principal Property" is defined to include
   any single manufacturing, production, distribution or service
   facility, plant or warehouse owned or leased by the Company or any
   Restricted Subsidiary (excluding all related land but including
   fixtures, machinery and equipment) which is located within the United
   States or Canada and the gross book value (without deduction of any
   depreciation reserves) of which on the date as of which the
   determination is being made exceeds 1% of Consolidated Net Tangible
   Assets, other than any such facility, plant or warehouse or portion
   thereof which, in the opinion of the Board of Directors, is not of
   material importance to the total business conducted by the Company and
   its subsidiaries as an entirety.  As of the date hereof, approximately
   ten of the Company's properties would be Principal Properties.  The
   term "Attributable Debt" is defined to mean the total net amount of
   rent required to be paid during the remaining term of certain leases,
   discounted at the weighted average rate per annum borne by the Debt
   Securities compounded semi-annually.  The term "Consolidated Net
   Tangible Assets" is defined as the aggregate amount of assets (less
   applicable reserves and other properly deductible items) after
   deducting therefrom (a) all current liabilities (excluding any thereof
   constituting Funded Debt by reason of their being renewable or
   extendible) and (b) all goodwill, trade names, trademarks, patents,
   unamortized debt discount and expense and other like intangibles, all
   as set forth on the most recent consolidated balance sheet of the
   Company and its consolidated and computed in accordance with generally
   accepted accounting principles.  (Section 101)

   RESTRICTIONS ON SECURED DEBT

        If the Company or any Restricted Subsidiary shall incur, issue,
   assume or guarantee any Debt secured by a Mortgage on any Principal
   Property or by a Mortgage on any shares of stock or Debt of any
   Restricted Subsidiary, the Company will secure or cause such
   Restricted Subsidiary to secure the Debt Securities, equally and
   ratably with (or prior to) such Secured Debt, unless after giving
   effect thereto the aggregate amount of all such Debt so secured,
   together with all Attributable Debt in respect of sale and leaseback
   transactions involving Principal Properties (see "Restrictions on
   Sales and Leasebacks" below), would not exceed 10% of Consolidated Net
   Tangible Assets.  This restriction will not apply to, and there will
   be excluded from secured Debt in any computation under such
   restriction, Debt secured by (a) Mortgages on property of, or on any
   shares of stock or Debt of, any corporation existing at the time such
   corporation becomes a Restricted Subsidiary, (b) Mortgages on
   property, shares of stock or Debt existing at the time of acquisition
   thereof (including acquisition through merger or consolidation), (c)
   Mortgages on property, shares of stock or Debt hereafter acquired (or,
   in the case of property, constructed) by the Company or any Restricted
   Subsidiary and created prior to, at the time of, or within 120 days
   after acquisition (or, in the case of property, the completion of
   construction and commencement of commercial operation, whichever is
   later) to secure or provide for the purchase price (or, in the case of

                                     23<PAGE>





   property, construction price) thereof, (d) Mortgages in favor of the
   Company or a Restricted Subsidiary, (e) Mortgages in favor of the
   United States or any State thereof, or Canada or any Province thereof,
   or any instrumentality of any thereof to secure progress, advance or
   other payments pursuant to any contract or provision of any statute,
   and (f) any extension, renewal or replacement of any Mortgage referred
   to in the foregoing clauses (a) through (e), inclusive.  (Section
   1007)

   RESTRICTIONS ON CERTAIN UNSECURED DEBT

        The Debt (other than Secured Debt referenced under "Restrictions
   on Secured Debt" above) of all consolidated Restricted Subsidiaries
   may not exceed 15% of the Consolidated Net Tangible Assets of the
   Company.  (Section 1011)

   MERGER AND CONSOLIDATION

        The Company may not consolidate with or merge into any other
   corporation or convey, transfer or lease its properties and assets
   substantially as an entirety to any Person, or permit any Person to
   consolidate with or merge into the Company or convey, transfer or
   lease its properties and assets substantially as an entirety to the
   Company, unless (i) either the Company shall be the continuing
   corporation or the successor or purchasing Person shall be a domestic
   corporation and shall expressly assume the payment of the principal of
   and premium, if any, and interest, if any, on the Debt Securities and
   the performance of every covenant of the Indenture binding upon the
   Company, (ii) immediately after such transaction no Event of Default,
   and no event which, after notice or lapse of time or both, would
   become an Event of Default, shall have happened and be continuing,
   (iii) if, as a result of the transaction, properties or assets of the
   Company would become subject to an encumbrance not permitted by the
   Indenture, the Company or such successor corporation or Person shall
   take steps necessary to secure the Debt Securities equally and ratably
   with (or prior to) all indebtedness secured by such encumbrance and
   (iv) the Company has delivered to the Trustee an Officer's Certificate
   and an Opinion of Counsel stating that such transaction complies with
   the Indenture.  (Section 801)

   RESTRICTIONS ON SALES AND LEASEBACKS

        Neither the Company nor any Restricted Subsidiary may enter into
   any sale and leaseback transaction involving any Principal Property,
   completion of construction and commencement of commercial operation of
   which has occurred more than 120 days prior thereto, unless (a) the
   Company or such Restricted Subsidiary could mortgage such property
   pursuant to the restrictions on secured Debt described above in an
   amount equal to the Attributable Debt with respect to the sale and
   leaseback transaction without equally and ratably securing the Debt
   Securities or (b) the Company, within 120 days, applies to the
   retirement of its Funded Debt an amount equal to the greater of (i)

                                     24<PAGE>





   the net proceeds of the sale of the Principal Property so leased
   pursuant to such arrangement or (ii) the fair value of the Principal
   Property so leased (subject to credits for certain voluntary
   retirements of Funded Debt and Debt Securities).  This restriction
   will not apply to any sale and lease-back transaction (a) between the
   Company and a Restricted Subsidiary or between Restricted Subsidiaries
   or (b) involving a lease for a period of less than three years. 
   (Section 1008)

   MODIFICATION AND WAIVER

        Modification and amendment of the Indenture may be effected by
   the Company and the Trustee with the consent of the Holders of not
   less than 66 % in principal amount of the Outstanding Debt Securities
   of each series affected thereby, provided that no such modification or
   amendment may, without the consent of the Holder of each Outstanding
   Security affected thereby, (a) change the Stated Maturity of any
   installment of principal of, or interest on, any Debt Security or
   change the redemption price; (b) reduce the principal amount of, or
   interest on, any Debt Security; (c) change the place or currency of
   any payment of principal or interest on any Debt Security; (d) impair
   the right to institute suit for the enforcement of any payment on or

   consent of whose Holders is required to modify or amend the Indenture;
   or (f) modify the foregoing requirements or reduce to less than a
   majority the percentage of Outstanding Debt Securities necessary to
   waive any past default.  Except with respect to certain fundamental
   provisions, the Holders of not less than a majority in principal
   amount of Outstanding Debt Securities of any series may, with respect
   to such series, waive past defaults under the Indenture and waive
   compliance by the Company with certain provisions of the Indenture. 
   (Sections 902, 513)

   EVENTS OF DEFAULT

        Under the Indenture, the following will be Events of Default with
   respect to any series of Debt Securities:  (a) default in the payment
   of any interest upon any Debt Security of that series when due,
   continued for 30 days; (b) default in the payment of any principal or
   premium, if any, on any Debt Security of that series when due; (c)
   default in the deposit of any sinking fund payment, when due, in
   respect of any Debt Security of that series; (d) default in the
   performance, or breach, of any other covenant or warranty of the
   Company contained in the Indenture or in the Debt Securities of such
   series, continued for 60 days after written notice as provided in the
   Indenture; (e) acceleration of any indebtedness for money borrowed in
   an aggregate principal amount exceeding $10,000,000 by the Company
   under the terms of the instrument under which such indebtedness is
   issued or secured, if such acceleration is not annulled, or such
   indebtedness is not discharged, within 10 days after written notice as
   provided in the Indenture; (f) certain events in bankruptcy,

                                     25<PAGE>





   insolvency or reorganization; and (g) any other Event of Default with
   respect to Debt Securities of that series.  The Trustee or the Holders
   of 25% in principal amount of the Outstanding Debt Securities of that
   series may declare the principal amount of all Outstanding Debt
   Securities of that series due and payable immediately if any Event of
   Default with respect to Debt Securities of such series shall occur and
   be continuing at the time of declaration.  At any time after
   declaration of acceleration has been made with respect to Debt
   Securities of any series but before a judgment or decree for payment
   of money due has been obtained by the Trustee, the Holders of a
   majority in principal amount of Outstanding Debt Securities of that
   series may rescind any declaration of acceleration and its
   consequences, if all payments due (other than those due as a result of
   acceleration) have been made and all Events of Default have been cured
   or waived.  Any Event of Default with respect to Debt Securities of
   any series may be waived by the Holders of a majority in principal
   amount of all Outstanding Debt Securities of that series, except a
   default (i) in the payment of principal or premium, if any, or
   interest on any Debt Security of that series or (ii) in respect of a
   covenant or provision which cannot be modified or amended without the
   consent of the Holder of each Outstanding Debt Security of such series
   affected.  (Sections 501, 502, 513)

        The Holders of a majority in principal amount of the Outstanding
   Debt Securities of a series may direct the time, method and place of
   conducting any proceeding for any remedy available to the Trustee or
   exercising any trust or power conferred on the Trustee with respect to
   Debt Securities of such series, provided that such direction shall not
   be in conflict with any rule of law or the Indenture.  Before
   proceeding to exercise any right or power under the Indenture at the
   direction of such Holders, the Trustee shall be entitled to receive
   from such Holders reasonable indemnity against the costs, expenses and
   liabilities which might be incurred by it in complying with any such
   direction.  (Sections 512, 507)

        The Company is required to furnish to the Trustee annually a
   statement as to the fulfillment by the Company of all of its
   obligations under the Indenture.

                           DESCRIPTION OF WARRANTS

   GENERAL

        The Company may issue Warrants, including Warrants to purchase
   Debt Securities ("Debt Warrants"), as well as other types of Warrants
   ("Other Warrants").  Warrants may be issued independently or together
   with any securities and may be attached to or separate from such
   Securities.  Each series of Warrants will be issued under a separate
   warrant agreement (each a "Warrant Agreement") to be entered into
   between the Company and a warrant agent ("Warrant Agent").  The
   Warrant Agent will act solely as an agent of the Company in connection
   with the Warrants of such series and will not assume any obligation or
   relationship of agency or trust for or with any holders or beneficial
   owners of Warrants.  The summary of terms of the Debt Warrants and the
   Other Warrants contained in this Prospectus does not purport to be
   complete and is subject to, and qualified in its entirety by reference
   to, the form of the Warrant Agreement which has been or will be filed
   with the Commission at or prior to the time of the offering of such
   Warrants.

   offered thereby will describe the following terms of such Other

   (which may include Preferred Stock, Depositary Shares or Common Stock)

                            PLAN OF DISTRIBUTION

        The Company may sell Securities to or through underwriters and
   also may sell Securities directly to other purchasers or through
   agents.  Any such underwriter(s) or agent(s) included in the offer and
   sale of Securities will be named in the applicable Prospectus
   Supplement.

        The distribution of the Securities may be effected from time to
   time in one or more transactions at a fixed price or prices, which may
   be changed, or at market prices prevailing at the time of sale, at
   prices related to such prevailing market prices or at negotiated
   prices.

        In connection with the sale of Securities, underwriters may
   receive compensation from the Company or from purchasers of Securities
   for whom they act as agents in the form of discounts, concessions or
   commissions.  Underwriters may sell Securities to or through dealers,
   and such dealers may receive compensation in the form of discounts,
   concessions or commissions from the underwriters and/or commissions
   from the purchasers for whom they may act as agents.  Underwriters,
   dealers and agents that participate in the distribution of Securities
   may be deemed to be underwriters, and any discounts or commissions
   received by them from the Company and any profit on the resale of
   Securities by them may be deemed to be underwriting discounts and
   commissions, under the Securities Act.

        A Prospectus Supplement will set forth the terms of Securities
   offered hereby, including the name or names of any underwriters, the
   purchase price of Securities, and proceeds to the Company from the

                                     28<PAGE>





   sale, any underwriting discounts and other items constituting
   underwriters' compensation, any public offering price, any discounts
   or concessions allowed or reallowed or paid to dealers, and any
   securities exchange or market on which Securities may be listed.  Only
   underwriters so named in such Prospectus Supplement are deemed to be
   underwriters in connection with Securities offered thereby.

        Under agreements which may be entered into by the Company,
   underwriters and agents who participate in the distribution of
   Securities may be entitled to indemnification by the Company against
   certain liabilities, including liabilities under the Securities Act.

        If so indicated in the Prospectus Supplement, the Company will
   authorize underwriters or other persons acting as the Company's agents
   to solicit offers by certain institutions to purchase Securities from
   the Company pursuant to contracts providing for payment and delivery
   on a future date.  Institutions with which such contracts may be made
   include commercial and savings banks, insurance companies, pension
   funds, investment companies, educational and charitable institutions
   and others, but in all cases such institutions must be approved by the
   Company.  The obligations of any purchaser under any such contract
   will be subject to the condition that the purchase of the Securities
   shall not at the time of delivery be prohibited under the laws of the
   jurisdiction to which such purchaser is subject.  The underwriters and
   such other agents will not have any responsibility in respect of the
   validity or performance of such contracts.


                               LEGAL OPINIONS

        The validity of any Securities will be passed upon for the
   Company by Schiff Hardin & Waite, Chicago, Illinois, and for the
   Underwriters by counsel selected by the Underwriters and acceptable to
   the Company.


                                   EXPERTS

        The consolidated financial statements of the Company incorporated
   by reference in this Prospectus, and elsewhere in the registration

   ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

        Article Fourteenth of the Registrant's Restated Certificate of
   Incorporation provides that no director of the Registrant shall have
   personal liability to the Registrant or its stockholders for monetary
   damages for breach of fiduciary duty as a director, but this provision
   does not eliminate or limit the liability of a director (a) for any
   breach of the director's duty of loyalty to the Registrant or its
   stockholders, (b) for acts or omissions not in good faith or which
   involve intentional misconduct or a knowing violation of law, (c)
   under section 174 of the General Corporation Law of the State of
   Delaware (the "GCL") or (d) for any transaction from which the
   director derived an improper personal benefit.

        Reference is made to Section 145 of the GCL, which provides for
   indemnification of directors and officers in certain circumstances. 
   Article Fifteenth of the Registrant's Restated Certificate of
   Incorporation provides for indemnification of the Registrant's
   officers and directors (and those serving in such capacity with
   another corporation at the request of the Registrant) to the fullest
   extent provided by the GCL and other applicable laws as currently in
   effect and as they may be amended in the future.

        The Registrant has directors' and officers' liability insurance
   which provides, subject to certain policy limits, deductible amounts
   and exclusions, coverage for all persons who have been, are or may in
   the future be, directors or officers of the Registrant against amounts
   which such persons must pay resulting from claims made against them by
   reason of their being such directors or officers during the policy

                                    II-1<PAGE>





   period for certain breaches of duty, omissions or other acts done or
   wrongfully attempted or alleged.

        The Registrant has entered into Indemnification Agreements with
   each of its directors and executive officers containing, among other
   things, provisions similar to those in the Registrant's Restated
   Certificate of Incorporation, including provisions requiring
   indemnification to the full extent permitted by the GCL and the prompt
   advancement of expenses under certain circumstances.  In addition, the
   Indemnification Agreements required the Registrant to maintain
   directors' and officers' liability insurance at specified levels,
   subject to certain exceptions, and, if such coverage is not
   maintained, to indemnify the directors and executive officers to the
   full extent of such coverage.

        The Underwriting Agreement to be filed as an exhibit hereto will
   provide for the indemnification of directors and officers of the
   Registrant by the Underwriters under certain circumstances.


   ITEM 16.  EXHIBITS

        The Exhibits filed herewith are set forth on the Exhibit Index
   filed as part of this Registration Statement.


   ITEM 17.  UNDERTAKINGS

           (a)  The undersigned Registrant hereby undertakes:

                 (1) To file, during any period in which offers or sales are
        being made, a post-effective amendment to this Registration
        Statement;
   
                (i)  To include any prospectus required by Section 10(a)(3)
        of the Securities Act of 1933;
   
                (ii)  To reflect in the prospectus any facts or events
        arising after the effective date of the Registration Statement
        (or the most recent post-effective amendment thereof) which,
        individually or in the aggregate, represent a fundamental change
        in the information set forth in the Registration Statement. 
        Notwithstanding the foregoing, any increase or decrease in volume
        of securities offered (if the total dollar value of securities
        offered would not exceed that which was registered) and any
        deviation from the low or high end of the estimated maximum
        offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate,
        the changes in volume and price represent no more than a 20
        percent change in the maximum aggregate offering price set forth
        in the "Calculation of Registration Fee" table in the effective
        Registration Statement;

                                    II-2<PAGE>





   
                (iii)  To include any material information with respect to
        the plan of distribution not previously disclosed in the
        Registration Statement or any material change to such information
        in the Registration Statement.

                  PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and
             (a)(1)(ii) do not apply if the Registration Statement is on
             Form S-3, Form S-8 or Form F-3, and the information required
             to be included in a post-effective amendment by those
             paragraphs is contained in periodic reports filed with or
             furnished to the Commission by the Registrant pursuant to
             Section 13 or 15(d) of the Securities Exchange Act of 1934
             that are incorporated by reference in the Registration
             Statement.
   
                (2)  That, for the purpose of determining any liability
        under the Securities Act of 1933, each such post-effective
        amendment shall be deemed to be a new Registration Statement
        relating to the securities offered therein, and the offering of
        such securities at that time shall be deemed to be the initial
        BONA FIDE offering thereof.

                (3)  To remove from registration by means of a
        post-effective amendment any of the securities being registered
        which remain unsold at the termination of the offering.
   
        (b)  The undersigned Registrant hereby undertakes that, for
   purposes of determining any liability under the Securities Act of
   1933, each filing of the registrant's annual report pursuant to
   Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and,
   where applicable, each filing of an employee benefit plan's annual
   report pursuant to Section 15(d) of the Securities Exchange Act of
   1934) that is incorporated by reference in the Registration Statement
   shall be deemed to be a new Registration Statement relating to the
   securities offered therein, and the offering of such securities at
   that time shall be deemed to be the initial BONA FIDE offering
   thereof.

        (c)  Insofar as indemnification for liabilities arising under the
   Securities Act of 1933 may be permitted to directors, officers and
   controlling persons of the registrant pursuant to the foregoing
   provisions, or otherwise, the registrant has been advised that in the
   opinion of the Securities and Exchange Commission such indemnification
   is against public policy as expressed in the Act and is, therefore,
   unenforceable.  In the event that a claim for indemnification against
   such liabilities (other than the payment by the registrant of expenses
   incurred or paid by a director, officer or controlling person of the
   registrant in the successful defense of any action, suit or
   proceeding) is asserted by such directors, officer or controlling
   person in connection with the securities being registered, the
   registrant will, unless in the opinion of its counsel the matter has

                                    II-3<PAGE>





   been settled by controlling precedent, submit to a court of
   appropriate jurisdiction the question whether such indemnification by
   it is against public policy as expressed in the Act and will be
   governed by the final adjudication of such issue.

             been duly and validly authorized and issued, are fully paid
             and non-assessable, and are owned directly or indirectly by
             the Company, free and clear of all liens, encumbrances,
             equities or claims (such counsel being entitled to rely in
             respect of the opinion in this clause upon opinions of local
             counsel and in respect to matters of fact upon certificates
             of officers of the Company or its subsidiaries, provided
             that such counsel shall state that they believe that both
             you and they are justified in relying upon such opinions and
             certificates);

                                     13<PAGE>





                  (iv) To the best of such counsel's knowledge and other
             than as set forth in the Prospectus, there are no legal or
             governmental proceedings pending to which the Company or any
             of its subsidiaries is a party or of which any property of
             the Company or any of its subsidiaries is the subject which,
             taking into account the likelihood of the outcome, the
             damages or other relief sought and other relevant factors,
             would individually or in the aggregate reasonably be
             expected to have a material adverse effect on the current or
             future consolidated financial position, stockholders' equity
             or results of operations of the Company and its
             subsidiaries; and, to the best of such counsel's knowledge,
             no such proceedings are threatened or contemplated by
             governmental authorities or threatened by others;

                  (v)  The documents incorporated by reference in the
             Prospectus or any further amendment or supplement thereto
             made by the Company prior to such Time of Delivery (other
             than the financial statements and related schedules therein,
             as to which such counsel need express no opinion), when they
             became effective or were filed with the Commission, as the
             case may be, complied as to form in all material respects
             with the requirements of the Act or the Exchange Act, as
             applicable, and the rules and regulations of the Commission
             thereunder; and he has no reason to believe that any of such
             documents, when such documents became effective or were so
             filed, as the case may be, contained, in the case of a
             registration statement which became effective under the Act,
             an untrue statement of a material fact or omitted to state a
             material fact required to be stated therein or necessary to
             make the statements therein not misleading, or, in the case
             of other documents which were filed under the Exchange Act
             with the Commission, an untrue statement of a material fact
             or omitted to state a material fact necessary in order to
             make the statements therein, in the light of the
             circumstances under which they were made when such documents
             were so filed, not misleading, it being understood that such
             counsel need express no opinion as to the financial
             statements or other financial information included in any of
             the documents mentioned in this Clause and that such counsel
             may state that they have not independently verified factual
             statements in any such documents; and 

                  (vi) The Registration Statement and the Prospectus and
             any further amendments and supplements thereto made by the
             Company prior to such Time of Delivery (other than the
             financial statements and related schedules therein, as to
             which such counsel need express no opinion) comply as to
             form in all material respects with the requirements of the
             Act and the Trust Indenture Act and the rules and
             regulations thereunder; although he does not assume any
             responsibility for the accuracy, completeness or fairness of

                                     14<PAGE>





             statements contained in the Registration Statement or the
             Prospectus, except for those referred to in the opinion in
             subsections (vi) of Section 7(c)(i) hereof and he has no
             reason to believe that, as of its effective date, the
             Registration Statement or any amendment thereto made by the
             Company prior to such Time of Delivery (other than the
             financial statements and related schedules therein, as to
             which such counsel need express no opinion) contained an
             untrue statement of a material fact or omitted to state a
             material fact required to be stated therein or necessary to
             make the statements therein not misleading or that, as of
             its date, the Prospectus or any amendment or supplement
             thereto made by the Company prior to such Time of Delivery
             (other than the financial statements and related schedules
             therein, as to which such counsel need express no opinion)
             contained an untrue statement of a material fact or omitted
             to state a material fact necessary to make the statements
             therein, in the light of the circumstances under which they
             were made, not misleading or that, as of such Time of
             Delivery, either the Registration Statement or the
             Prospectus or any amendment or supplement thereto made by
             the Company prior to such Time of Delivery (other than the
             financial statements and related schedules therein, as to
             which such counsel need express no opinion) contains an
             untrue statement of a material fact or omits to state a
             material fact necessary to make the statements therein, in
             the light of the circumstances under which they were made,
             not misleading; and he does not know of any amendment to the
             Registration Statement required to be filed or of any
             contracts or other documents of a character required to be
             filed as an exhibit to the Registration Statement or
             required to be incorporated by reference into the Prospectus
             or required to be described in the Registration Statement or
             the Prospectus which are not filed or incorporated by
             reference or described as required.

             (d)  On the date of the Prospectus at a time prior to the
   execution of this agreement, at ________________, on the effective
   date of any post-effective amendment to the Registration Statement
   filed subsequent to the date of this Agreement and also at the Time of
   Delivery, KPMG Peat Marwick, LLP shall have furnished to you a letter
   or letters, dated the respective dates of delivery thereof, in form
   and substance satisfactory to you;

             (e)  (i)  Neither the Company nor any of its subsidiaries
   shall have sustained since the date of the latest audited financial
   statements included or incorporated by reference in the Prospectus any
   loss or interference with its business from fire, explosion, flood or
   other calamity, whether or not covered by insurance, or from any labor
   dispute or court or governmental action, order or decree, otherwise
   than as set forth or contemplated in the Prospectus which could
   reasonably be expected to have a material adverse effect on the

                                     15<PAGE>





   financial position, stockholders' equity or result of operations of
   the Company and its subsidiaries, considered as a whole, and (ii)
   since the respective dates as of which information is given in the
   Prospectus there shall not have been any change in the capital stock
   or long-term debt of the Company or any of its subsidiaries the
   Company and its subsidiaries shall not have incurred any material
   liabilities or obligations, direct or contingent, or entered into any
   material transactions not in the ordinary course of business or there
   shall not have occurred or any change, or any development involving a
   prospective change, in or affecting the general affairs, management,
   financial position, stockholders' equity or results of operations of
   the Company and its subsidiaries, considered as a whole, otherwise
   than as set forth or contemplated in the Prospectus, the effect of
   which, in any such case described in Clause (i) or (ii), is in the
   judgment of each Underwriter so material and adverse as to make it
   impracticable or inadvisable to proceed with the public offering or
   the delivery of the Securities on the terms and in the manner
   contemplated in the Prospectus; 

             (f)  On or after the date hereof (i) no downgrading shall
   have occurred in the rating accorded the Company's debt securities by
   any "nationally recognized statistical rating organization", as that
   term is defined by the Commission for purposes of Rule 436(g)(2) under
   the Act, and (ii) no such organization shall have publicly announced
   that it has under surveillance or review, with possible negative
   implications, its rating of any of the Company's debt securities; 

             (g)  On or after the date hereof there shall not have
   occurred any of the following: (i) a suspension or material limitation
   in trading in securities generally on the New York Stock Exchange;
   (ii) a suspension or material limitation in trading in the Company's
   securities on the New York Stock Exchange; (iii) a general moratorium
   on commercial banking activities declared by either Federal or New
   York or Illinois authorities; or (iv) the outbreak or escalation of
   hostilities involving the United States or the declaration by the
   United States of a national emergency or war, if the effect of any
   such event specified in this Clause (iv) in the judgment of the
   Underwriters makes it impracticable or inadvisable to proceed with the
   public offering or the delivery of the Securities on the terms and in
   the manner contemplated in the Prospectus; and (i) The Company has
   obtained and delivered to the Underwriters executed copies of an
   agreement from the executive officers and directors of the Company,
   substantially to the effect set forth in Subsection 5(e) hereof in
   form and substance satisfactory to you; 

             (h)  The Company shall have furnished or caused to be
   furnished to you at the Time of Delivery certificates of officers of
   the Company satisfactory to you as to the accuracy of the
   representations and warranties of the Company herein at and as of such
   Time of Delivery, as to the performance by the Company of all of its
   obligations hereunder to be performed at or prior to such Time of
   Delivery, as to the matters set forth in subsections (a) and (e) of

                                     16<PAGE>





   this Section and as to such other matters as you may reasonably
   request; and

             (i)  The Company shall have complied with the provisions of
   Section 5(c) hereof with respect to the furnishing of Prospectuses on
   ________________.

        8.   (a)  The Company will indemnify and hold harmless each
   Underwriter against any losses, claims, damages or liabilities, joint
   or several, to which such Underwriter may become subject, under the
   Act or otherwise, insofar as such losses, claims, damages or
   liabilities (or actions in respect thereof) arise out of or are based
   upon an untrue statement or alleged untrue statement of a material
   fact contained in any Preliminary Prospectus, the Registration
   Statement or the Prospectus, or any amendment or supplement thereto,
   or arise out of or are based upon the omission or alleged omission to
   state therein a material fact required to be stated therein or
   necessary to make the statements therein not misleading, and will
   reimburse each Underwriter for any legal or other expenses reasonably
   incurred by such Underwriter in connection with investigating or
   defending any such action or claim as such expenses are incurred;
   provided, however, that the Company shall not be liable in any such
   case to the extent that any such loss, claim, damage or liability
   arises out of or is based upon an untrue statement or alleged untrue
   statement or omission or alleged omission made in any Preliminary
   Prospectus, the Registration Statement or the Prospectus or any such
   amendment or supplement in reliance upon and in conformity with
   written information furnished to the Company by any Underwriter
   expressly for use therein. 

             (b)  Each Underwriter will indemnify and hold harmless the
   Company against any losses, claims, damages or liabilities to which
   the Company may become subject, under the Act or otherwise, insofar as
   such losses, claims, damages or liabilities (or actions in respect
   thereof) arise out of or are based upon an untrue statement or alleged
   untrue statement of a material fact contained in any Preliminary
   Prospectus, the Registration Statement or the Prospectus, or any
   amendment or supplement thereto, or arise out of or are based upon the
   omission or alleged omission to state therein a material fact required
   to be stated therein or necessary to make the statements therein not
   misleading, in each case to the extent, but only to the extent, that
   such untrue statement or alleged untrue statement or omission or
   alleged omission was made in any Preliminary Prospectus, the
   Registration Statement or the Prospectus or any such amendment or
   supplement in reliance upon and in conformity with written information
   furnished to the Company by such Underwriter expressly for use
   therein; and will reimburse the Company for any legal or other
   expenses reasonably incurred by the Company in connection with
   investigating or defending any such action or claim as such expenses
   are incurred. 



                                     17<PAGE>





             (c)  Promptly after receipt by an indemnified party under
   subsection (a) or (b) above of notice of the commencement of any
   action, such indemnified party shall, if a claim in respect thereof is
   to be made against the indemnifying party under such subsection,
   notify the indemnifying party in writing of the commencement thereof;
   but the omission so to notify the indemnifying party shall not relieve
   it from any liability which it may have to any indemnified party
   otherwise than under such subsection.  In case any such action shall
   be brought against any indemnified party and it shall notify the
   indemnifying party of the commencement thereof, the indemnifying party
   shall be entitled to participate therein and, to the extent that it
   shall wish, jointly with any other indemnifying party similarly
   notified, to assume the defense thereof, with counsel satisfactory to
   such indemnified party (who shall not, except with the consent of the
   indemnified party, be counsel to the indemnifying party), and, after
   notice from the indemnifying party to such indemnified party of its
   election so to assume the defense thereof, the indemnifying party
   shall not be liable to such indemnified party under such subsection
   for any legal expenses of other counsel or any other expenses, in each
   case subsequently incurred by such indemnified party, in connection
   with the defense thereof other than reasonable costs of investigation. 
   No indemnifying party shall, without the written consent of the
   indemnified party, effect the settlement or compromise of, or consent
   to the entry of any judgment with respect to, any pending or
   threatened action or claim in respect of which indemnification or
   contribution may be sought hereunder (whether or not the indemnified
   party is an actual or potential party to such action or claim) unless
   such settlement, compromise or judgment (i) includes an unconditional
   release of the indemnified party from all liability arising out of
   such action or claim and (ii) does not include a statement as to or an
   admission of fault, culpability or a failure to act, by or on behalf
   of any indemnified party.

             (d)  If the indemnification provided for in this Section 8
   is unavailable to or insufficient to hold harmless an indemnified
   party under subsection (a) or (b) above in respect of any losses,
   claims, damages or liabilities (or actions in respect thereof)
   referred to therein, then each indemnifying party shall contribute to
   the amount paid or payable by such indemnified party as a result of
   such losses, claims, damages or liabilities (or actions in respect
   thereof) in such proportion as is appropriate to reflect the relative
   benefits received by the Company on the one hand and the Underwriters
   on the other from the offering of the Securities.  If, however, the
   allocation provided by the immediately preceding sentence is not
   permitted by applicable law or if the indemnified party failed to give
   the notice required under subsection (c) above, then each indemnifying
   party shall contribute to such amount paid or payable by such
   indemnified party in such proportion as is appropriate to reflect not
   only such relative benefits but also the relative fault of the Company
   on the one hand and the Underwriters on the other in connection with
   the statements or omissions which resulted in such losses, claims,
   damages or liabilities (or actions in respect thereof), as well as any

                                     18<PAGE>





   other relevant equitable considerations.  The relative benefits
   received by the Company on the one hand and the Underwriters on the
   other shall be deemed to be in the same proportion as the total net
   proceeds from the offering (before deducting expenses) received by the
   Company bear to the total underwriting discounts and commissions
   (before deducting expenses) received by the Underwriters, in each case
   as set forth in the table on the cover page of the Prospectus.  The
   relative fault shall be determined by reference to, among other
   things, whether the untrue or alleged untrue statement of a material
   fact or the omission or alleged omission to state a material fact
   relates to information supplied by the Company on the one hand or the
   Underwriters on the other and the parties' relative intent, knowledge,
   access to information and opportunity to correct or prevent such
   statement or omission.  The Company and the Underwriters agree that it
   would not be just and equitable if contributions pursuant to this
   subsection (d) were determined by pro rata allocation (even if the
   Underwriters were treated as one entity for such purpose) or by any
   other method of allocation which does not take account of the
   equitable considerations referred to above in this subsection (d). 
   The amount paid or payable by an indemnified party as a result of the
   losses, claims, damages or liabilities (or actions in respect thereof)
   referred to above in this subsection (d) shall be deemed to include
   any legal or other expenses reasonably incurred by such indemnified
   party in connection with investigating or defending any such action or
   claim.  Notwithstanding the provisions of this subsection (d), no
   Underwriter shall be required to contribute any amount in excess of
   the amount by which the total price at which the Securities
   underwritten by it and distributed to the public were offered to the
   public exceeds the amount of any damages which such Underwriter has
   otherwise been required to pay by reason of such untrue or alleged
   untrue statement or omission or alleged omission.  No person guilty of
   fraudulent misrepresentation (within the meaning of Section 11(f) of
   the Act) shall be entitled to contribution from any person who was not
   guilty of such fraudulent misrepresentation.  The Underwriters'
   obligations in this subsection (d) to contribute are several in
   proportion to their respective underwriting obligations and not joint.

             (e)  The obligations of the Company under this Section 8
   shall be in addition to any liability which the Company may otherwise
   have and shall extend, upon the same terms and conditions, to each
   person, if any, who controls any Underwriter within the meaning of the
   Act; and the obligations of the Underwriters under this Section 8
   shall be in addition to any liability which the respective
   Underwriters may otherwise have and shall extend, upon the same terms
   and conditions, to each officer and director of the Company and to
   each person, if any, who controls the Company within the meaning of
   the Act. 

        9.   (a)  If any Underwriter shall default in its obligation to
   purchase the Securities which it has agreed to purchase hereunder, you
   may in your discretion arrange for you or another party or other
   parties to purchase such Securities on the terms contained herein.  If

                                     19<PAGE>





   within _______ after such default by any Underwriter you do not
   arrange for the purchase of such Securities, then the Company shall be
   entitled to a further period of _______ within which to procure
   another party or other parties satisfactory to you to purchase such
   Securities on such terms.  In the event that, within the respective
   prescribed periods, you notify the Company that you have so arranged
   for the purchase of such Securities, or the Company notifies you that
   it has so arranged for the purchase of such Securities, you or the
   Company shall have the right to postpone the Time of Delivery for a
   period of not more than _________, in order to effect whatever changes
   may thereby be made necessary in the Registration Statement or the
   Prospectus, or in any other documents or arrangements, and the Company
   agrees to file promptly any amendments to the Registration Statement
   or the Prospectus which in your opinion may thereby be made necessary. 
   The term "Underwriter" as used in this Agreement shall include any
   person substituted under this Section with like effect as if such
   person had originally been a party to this Agreement with respect to
   such Securities. 

             (b)  If, after giving effect to any arrangements for the
   purchase of the Securities of a defaulting Underwriter or Underwriters
   by you and the Company as provided in subsection (a) above, the
   aggregate principal amount of such Securities which remains
   unpurchased does not exceed __________ of the aggregate principal
   amount of all the Securities, then the Company shall have the right to
   require each non-defaulting Underwriter to purchase the principal
   amount of Securities which such Underwriter agreed to purchase
   hereunder and, in addition, to require each non-defaulting Underwriter
   to purchase its pro rata share (based on the principal amount of
   Securities which such Underwriter agreed to purchase hereunder) of the
   Securities of such defaulting Underwriter or Underwriters for which
   such arrangements have not been made; but nothing herein shall relieve
   a defaulting Underwriter from liability for its default. 

             (c)  If, after giving effect to any arrangements for the
   purchase of the Securities of a defaulting Underwriter or Underwriters
   by you and the Company as provided in subsection (a) above, the
   aggregate principal amount of Securities which remains unpurchased
   exceeds ________ of the aggregate principal amount of all the
   Securities to be purchased at such time of Delivery or if the Company
   shall not exercise the right described in subsection (b) above to
   require non-defaulting Underwriters to purchase Securities of a
   defaulting Underwriter or Underwriters, then this Agreement shall
   thereupon terminate, without liability on the part of any
   non-defaulting Underwriter or the Company, except for the expenses to
   be borne by the Company and the Underwriters as provided in Section 6
   hereof and the indemnity and contribution agreements in Section 8
   hereof; but nothing herein shall relieve a defaulting Underwriter from
   liability for its default.

        10.  The respective indemnities, agreements, representations,
   warranties and other statements of the Company and the several

                                     20<PAGE>





   Underwriters, as set forth in this Agreement or made by or on behalf
   of them, respectively, pursuant to this Agreement, shall remain in
   full force and effect, regardless of any investigation (or any
   statement as to the results thereof) made by or on behalf of any
   Underwriter or any controlling person of any Underwriter, or the
   Company, or any officer or director or controlling person of the
   Company, and shall survive delivery of and payment for the Securities.

        Anything herein to the contrary notwithstanding, the indemnity
   agreement of the Company in subsection (a) of Section 8 hereof, the
   representations and warranties in subsections (b), (c) and (d) of
   Section 1 hereof and any representation or warranty as to the accuracy
   of the Registration Statement or the Prospectus contained in any
   certificate furnished by the Company pursuant to Section 7 hereof,
   insofar as they may constitute a basis for indemnification for
   liabilities (other than payment by the Company of expenses incurred or
   paid in the successful defense of any action, suit or proceeding)
   arising under the Act, shall not extend to the extent of any interest
   therein of a controlling person or partner of an Underwriter who is a
   director, officer or controlling person of the Company when the
   Registration Statement has become effective, except in each case to
   the extent that an interest of such character shall have been
   determined by a court of appropriate jurisdiction as not against
   public policy as expressed in the Act.  Unless in the opinion of
   counsel for the Company the matter has been settled by controlling
   precedent, the Company will, if a claim for such indemnification is
   asserted, submit to a court of appropriate jurisdiction the question
   of whether such interest is against public policy as expressed in the
   Act and will be governed by the final adjudication of such issue. 

        11.  If this Agreement shall be terminated pursuant to Section 9
   hereof, the Company shall not then be under any liability to any
   Underwriter except as provided in Sections 6 and 8 hereof; but, if for
   any other reason, the Securities are not delivered by or on behalf of
   the Company as provided herein, the Company will reimburse the
   Underwriters through you for all out-of-pocket expenses approved in
   writing by you, including fees and disbursements of counsel,
   reasonably incurred by the Underwriters in making preparations for the
   purchase, sale and delivery of the Securities, but the Company shall
   then be under no further liability to any Underwriter except as
   provided in Sections 6 and 8 hereof.

        12.  In all dealings hereunder, you shall act on behalf of the
   other Underwriter, and the parties hereto shall be entitled to act and
   rely upon any statement, request, notice or agreement on behalf of the
   Underwriters made or given by you jointly or by ________________ on
   behalf of you. 

        All statements, requests, notices and agreements hereunder shall
   be in writing, and if to the Underwriters shall be delivered or sent
   by mail, telex or facsimile transmission to you in care of
   ________________ at ________________________; and if to the Company

                                     21<PAGE>





   shall be delivered or sent by mail, telex or facsimile transmission to
   the address of the Company set forth in the Registration Statement,
   Attention: Secretary; provided, however, that any notice to an
   Underwriter pursuant to Section 8(c) hereof shall be delivered or sent
   by mail, telex or facsimile transmission to such Underwriter at its
   address set forth in its Underwriters' Questionnaire, or telex

   related matters as you may reasonably request, and such counsel shall

   Time of Delivery, in form and substance satisfactory to you, to the
   effect that:

                  (i)  The Company has been duly incorporated and is
             validly existing as a corporation in good standing under the
             laws of the State of Delaware, with corporate power and

             by the Company with all of the provisions of this Agreement

             will not conflict with or result in a breach or violation of
             any of the terms or provisions of, or constitute a default
             under, any indenture, mortgage, deed of trust, loan

             10-K, quarterly reports on Form 10-Q, or other Exchange Act
             filings, nor will such action result in any violation of the

             the Company or any statute or any order, rule or regulation
             known to such counsel of any court or governmental agency or
             body having jurisdiction over the Company or any of its
             subsidiaries or any of their properties;

                  (v)  No consent, approval, authorization, order,
             filing, registration or qualification of or with any such
             court or governmental agency or body is required for the
             issue and sale of the Shares or the consummation by the
             Company of the transactions contemplated by this Agreement,
             except the registration under the Act of the Shares, and
             such consents, approvals, authorizations, filings,
             registrations or qualifications as may be required under


                                     12<PAGE>





             state securities or Blue Sky laws in connection with the
             purchase and distribution of the Shares by the Underwriters;

                  (vi)  The statements set forth in the Prospectus
             insofar as they purport to constitute a summary of the terms
             of the Stock and insofar as they purport to describe the
             provisions of the documents referred to therein, are
             accurate and complete in all material respects;

                  (vii)  The Company is not an "investment company" or an
             entity "controlled" by an "investment company", as such
             terms are defined in the Investment Company Act;

                  (viii)  The documents incorporated by reference in the
             Prospectus or any further amendment or supplement thereto
             made by the Company prior to such Time of Delivery (other
             than the financial statements and related schedules therein,
             as to which such counsel need express no opinion), when they
             became effective or were filed with the Commission, as the 
             case may be, complied as to form in all material respects
             with the  requirements of the Act or the Exchange Act, as
             applicable, and the rules and regulations of the Commission
             thereunder; and

                  (ix)  The Registration Statement and the Prospectus and
             any amendments and supplements thereto made by the Company
             prior to such Time of Delivery (other than the financial
             statements and related schedules therein, as to which such
             counsel need express no opinion) comply as to form in all
             material respects with the requirements of the Act and the
             rules and regulations thereunder; although they do not
             assume any responsibility for the accuracy, completeness or
             fairness of the statements contained in the Registration
             Statement or the Prospectus, except for those referred to in
             the opinion in subsection (vi) of this Section 7(c)(i), they
             have no reason to believe that, as of its effective date,
             the Registration Statement or any further amendment thereto
             made by the Company prior to such Time of Delivery (other
             than the financial statements and related schedules therein,
             as to which such counsel need express no opinion) contained
             an untrue statement of a material fact or omitted to state a
             material fact required to be stated therein or necessary to
             make the statements therein not misleading or that, as of
             its date, the Prospectus or any  amendment or supplement
             thereto made by the Company prior to such Time of Delivery
             (other than the financial statements and related schedules
             therein, as to which such counsel need express no opinion)
             contained an untrue statement of a material fact or omitted
             to state a material fact necessary to make the statements
             therein, in the light of the circumstances under which they
             were made, not misleading or that, as of such Time of
             Delivery, either the Registration Statement or the

                                     13<PAGE>





             Prospectus or any amendment or supplement thereto made by
             the Company prior to such Time of Delivery (other than the
             financial statements and related schedules therein, as to
             which such counsel need express no opinion) contains an
             untrue statement of a material fact or omits to state a
             material fact necessary to make the statements therein, in
             the light of the circumstances under which they were made,
             not misleading; and they do not know of any amendment to the
             Registration Statement required to be filed or of any
             contracts or other documents of a character required to be
             filed as an exhibit to the Registration Statement or
             required to be incorporated by reference into the Prospectus
             or required to be described in the Registration Statement or
             the Prospectus which are not filed or incorporated by
             reference or described as required.

        (ii) Howard A. Pulsifer, Esq., General Counsel of the Company,
   shall have furnished to you his written opinion, dated such Time of
   Delivery, in form and substance satisfactory to you, to the effect
   that:
    
                  (i)  The Company 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 which
             it owns or leases properties or conducts any business so as
             to require such qualification or is subject to no material
             liability or disability by reason of the failure to be so
             qualified in any such jurisdiction (such counsel being
             entitled to rely in respect of the opinion in this clause
             upon opinions of local counsel and in respect of matters of
             fact upon certificates of officers of the Company, provided
             that such counsel shall state that they believe that both
             you and they are justified in relying upon such opinions and 
             certificates);

                  (ii)  Each subsidiary of the Company has been duly
             incorporated and is validly existing as a corporation in
             good standing under the laws of its jurisdiction of
             incorporation, with corporate power and authority to own its
             properties and conduct its business as described in the
             Prospectus; and all of the issued shares of capital stock of
             each such subsidiary have been duly and validly authorized
             and issued, are fully paid and non-assessable, and are owned
             directly or indirectly by the Company, free and clear of all
             liens, encumbrances, equities or claims (such counsel being
             entitled to rely in respect of the opinion in this clause
             upon opinions of local counsel and in respect to matters of
             fact upon certificates of officers of the Company or its
             subsidiaries, provided that such counsel shall state that
             they believe that both you and they are justified in relying
             upon such opinions and certificates);


                                     14<PAGE>





                  (iii)  To the best of such counsel's knowledge and
             other than as set forth in the Prospectus, there are no
             legal or governmental proceedings pending to which the
             Company or any of its subsidiaries is a party or of which
             any property of the Company or any of its subsidiaries is
             the subject which, taking into account the likelihood of the
             outcome, the damages or other relief sought and other
             relevant factors, would individually or in the aggregate
             reasonably be expected to have a material adverse effect on
             the current or future consolidated financial position,
             stockholders' equity or results of operations of the Company
             and its subsidiaries; and, to the best of such counsel's
             knowledge, no such proceedings are threatened or
             contemplated by governmental authorities or threatened by
             others;

                  (iv)  The documents incorporated by reference in the
             Prospectus or any further amendment or supplement thereto
             made by the Company prior to such Time of Delivery (other
             than the financial statements and related schedules therein,
             as to which such counsel need express no opinion), when they
             became effective or were filed with the Commission, as the
             case may be, complied as to form in all material respects
             with the requirements of the Act or the Exchange Act, as
             applicable, and the rules and regulations of the Commission
             thereunder; and he has no reason to believe that any of such
             documents, when such documents became effective or were so
             filed, as the case may be, contained, in the case of a
             registration statement which became effective under the Act,
             an untrue statement of a material fact or omitted to state a
             material fact required to be stated therein or necessary to
             make the statements therein not misleading, or, in the case
             of other documents which were filed under the Exchange Act
             with the Commission, an untrue statement of a material fact
             or omitted to state a material fact necessary in order to
             make the statements therein, in the light of the
             circumstances under which they were made when such documents
             were so filed, not misleading, it being understood that such
             counsel need express no opinion as to the financial
             statements or other financial information included in any of
             the documents mentioned in this Clause and that such counsel
             may state that they have not independently verified factual
             statements in any such documents; and

                  (v)  The Registration Statement and the Prospectus and
             any further amendments and supplements thereto made by the
             Company prior to such Time of Delivery (other than the
             financial statements and related schedules therein, as to
             which such counsel need express no opinion) comply as to
             form in all material respects with the requirements of the
             Act and the rules and regulations thereunder; although they
             do not assume any responsibility for the accuracy,

                                     15<PAGE>





             completeness or fairness of the statements contained in the
             Registration Statement or the Prospectus, except for those
             referred to in the opinion in subsection  (vi) of Section
             7(c)(i) hereof, they have no reason to believe that, as of
             its effective date, the Registration Statement or any
             amendment thereto made by the Company prior to such Time of
             Delivery (other than the financial statements and related
             schedules therein, as to which such counsel need express no
             opinion) contained an untrue statement of a material fact or
             omitted to state a material fact required to be stated 
             therein or necessary to make the statements therein not
             misleading or that, as of its date, the Prospectus or any
             amendment or supplement thereto made by the Company prior to
             such Time of Delivery (other than the financial statements
             and related schedules therein, as to which such counsel need
             express no opinion) contained an untrue statement of a 
             material fact or omitted to state a material fact necessary
             to make the statements therein, in the light of the
             circumstances under which they were made, not misleading or
             that, as of such Time of Delivery, either the Registration
             Statement or the Prospectus or any amendment or supplement
             thereto made by the Company prior to such Time of Delivery 
             (other than the financial statements and related schedules
             therein, as to which such counsel need express no opinion)
             contains an untrue statement of a material fact or omits to
             state a material fact necessary to make the statements
             therein, in the light of the circumstances under which they
             were made, not misleading; and he does not know of any
             amendment to the Registration Statement required to be filed
             or of any contracts or other documents of a character
             required to be filed as an exhibit to the Registration
             Statement or required to be incorporated by  reference into
             the Prospectus or required to be described in the
             Registration Statement or the Prospectus which are not filed
             or incorporated by reference or described as required.

                  (d)  On the date of the Prospectus at a time prior to
   the execution of this Agreement, at ______________________, on the
   effective date of any post-effective amendment to the Registration
   Statement filed subsequent to the date of this Agreement and also at
   each Time of Delivery, KPMG Peat Marwick LLP shall have furnished to
   you a letter or letters, dated the respective dates of delivery
   thereof, in form and substance satisfactory to you;

                  (e)  (i)  Neither the Company nor any of its
   subsidiaries shall have sustained since the date of the latest audited
   financial statements included or incorporated by reference in the
   Prospectus any loss or interference with its business from fire,
   explosion, flood or other calamity, whether or not covered by
   insurance, or from any labor dispute or court or governmental action,
   order or decree, otherwise than as set forth or contemplated in the
   Prospectus, and (ii) since the respective dates as of which

                                     16<PAGE>





   information is given in the Prospectus there shall not have been any
   change in the capital stock or long-term debt of the Company or any of
   its subsidiaries, the Company and its subsidiaries shall not have
   incurred any material liabilities or obligations, direct or
   contingent, or entered into any material transactions not in the
   ordinary course of business, or there shall not have occurred any
   change, or any development involving a prospective change, in or
   affecting the general affairs, management, financial position,
   stockholders' equity or results of operations of the Company and its
   subsidiaries considered as a whole, otherwise than as set forth or
   contemplated in the Prospectus, the effect of which, in any such case
   described in Clause (i) or (ii), is in the judgment of the
   Representatives so material and adverse as to make it impracticable or
   inadvisable to proceed with the public offering or the delivery of the
   Shares being delivered at such Time of Delivery on the terms and in
   the manner contemplated in the Prospectus;

                  (f)  On or after the date hereof (i) no downgrading
   shall have occurred in the rating accorded the Company's debt
   securities by any "nationally recognized statistical rating
   organization", as that term is defined by the Commission for purposes
   of Rule 436(g)(2) under the Act, and (ii) no such organization shall
   have publicly announced that it has under surveillance or review, with
   possible negative implications, its rating of any of the Company's
   debt securities;

                  (g)  On or after the date hereof there shall not have
   occurred any of the following: (i) a suspension or material limitation
   in trading in securities generally on the Exchange; (ii) a suspension
   or material limitation in trading in the Company's securities on the
   Exchange; (iii) a general moratorium on commercial banking activities
   declared by either Federal, New York or Illinois authorities; or (iv)
   the outbreak or escalation of hostilities involving the United States
   or the declaration by the United States of a national emergency or
   war, if the effect of any such event specified in this Clause (iv) in
   the judgment of the Representatives makes it impracticable or
   inadvisable to proceed with the public offering or the delivery of the
   Shares being delivered at such Time of Delivery on the terms and in
   the manner contemplated in the Prospectus;

                  (h)  The Shares to be sold at such Time of Delivery
   shall have been duly listed, subject to notice of issuance, on the
   Exchange;

                  (i)  The Company has obtained and delivered to the
   Underwriters executed copies of an agreement from the executive
   officers and directors of the Company, substantially to the effect set
   forth in Subsection 5(e) hereof in form and substance satisfactory to
   you;




                                     17<PAGE>





                  (j)  The Company shall have complied with the
   provisions of Section 5(c) hereof with respect to the furnishing of
   prospectuses on ______________________; and

                  (k)  The Company shall have furnished or caused to be
   furnished to you at such Time of Delivery certificates of officers of
   the Company satisfactory to you as to the accuracy of the
   representations and warranties of the Company herein at and as of such
   Time of Delivery, as to the performance by the Company of all of its
   obligations hereunder to be performed at or prior to such Time of
   Delivery, as to the matters set forth in subsections (a) and (e) of
   this Section and as to such other matters as you may reasonably
   request.

             8.   (a)  The Company will indemnify and hold harmless each
   Underwriter against any losses, claims, damages or liabilities, joint
   or several, to which such Underwriter may become subject, under the
   Act or otherwise, insofar as such losses, claims, damages or
   liabilities (or actions in respect thereof) arise out of or are based
   upon an untrue statement or alleged untrue statement of a material
   fact contained in any Preliminary Prospectus, the Registration
   Statement or the Prospectus, or any amendment or supplement thereto,
   or arise out of or are based upon the omission or alleged omission to
   state therein a material fact required to be stated therein or
   necessary to make the statements therein not misleading, and will
   reimburse each Underwriter for any legal or other expenses reasonably
   incurred by such Underwriter in connection with investigating or
   defending any such action or claim as such expenses are incurred;
   provided, however, that the Company shall not be liable in any such
   case to the extent that any such loss, claim, damage or liability
   arises out of or is based upon an untrue statement or alleged untrue
   statement or omission or alleged omission made in any Preliminary
   Prospectus, the Registration Statement or the Prospectus or any such
   amendment or supplement in reliance upon and in conformity with
   written information furnished to the Company by any Underwriter
   expressly for use therein.

                  (b)  Each Underwriter will indemnify and hold harmless
   the Company against any losses, claims, damages or liabilities to
   which the Company may become subject, under the Act or otherwise,
   insofar as such losses, claims, damages or liabilities (or actions in
   respect thereof) arise out of or are based upon an untrue statement or
   alleged untrue statement of a material fact contained in any
   Preliminary Prospectus, the Registration Statement or the Prospectus,
   or any amendment or supplement thereto, or arise out of or are based
   upon the omission or alleged omission to state therein a material fact
   required to be stated therein or necessary to make the statements
   therein not misleading, in each case to the extent, but only to the
   extent, that such untrue statement or alleged untrue statement or
   omission or alleged omission was made in any Preliminary Prospectus,
   the Registration Statement or the Prospectus or any such amendment or
   supplement in reliance upon and in conformity with written information

                                     18<PAGE>





   furnished to the Company by such Underwriter expressly for use
   therein; and will reimburse the Company for any legal or other
   expenses reasonably incurred by the Company in connection with
   investigating or defending any such action or claim as such expenses
   are incurred. 

                  (c)  Promptly after receipt by an indemnified party
   under subsection (a) or (b) above of notice of the commencement of any
   action, such indemnified party shall, if a claim in respect thereof is
   to be made against the indemnifying party under such subsection,
   notify the indemnifying party in writing of the commencement thereof;
   but the omission so to notify the indemnifying party shall not relieve
   it from any liability which it may have to any indemnified party
   otherwise than under such subsection.  In case any such action shall
   be brought against any indemnified party and it shall notify the
   indemnifying party of the commencement thereof, the indemnifying party
   shall be entitled to participate therein and, to the extent that it
   shall wish, jointly with any other indemnifying party similarly
   notified, to assume the defense thereof, with counsel satisfactory to
   such indemnified party (who shall not, except with the consent of the
   indemnified party, be counsel to the indemnifying party), and, after
   notice from the indemnifying party to such indemnified party of its
   election so to assume the defense thereof, the indemnifying party
   shall not be liable to such indemnified party under such subsection
   for any legal expenses of other counsel or any other expenses, in each
   case subsequently incurred by such indemnified party, in connection
   with the defense thereof other than reasonable costs of investigation. 
   No indemnifying party shall, without the written consent of the
   indemnified party, effect the settlement or compromise of, or consent
   to the entry of any judgment with respect to, any pending or
   threatened action or claim in respect of which indemnification or
   contribution may be sought hereunder (whether or not the indemnified
   party is an actual or potential party to such action or claim) unless
   such settlement, compromise or judgment (i) includes an unconditional
   release of the indemnified party from all liability arising out of
   such action or claim and (ii) does not include a statement as to or an
   admission of fault, culpability or a failure to act, by or on behalf
   of any indemnified party.

                  (d)  If the indemnification provided for in this
   Section 8 is unavailable to or insufficient to hold harmless an
   indemnified party under subsection (a) or (b) above in respect of any
   losses, claims, damages or liabilities (or actions in respect thereof)
   referred to therein, then each indemnifying party shall contribute to
   the amount paid or payable by such indemnified party as a result of
   such losses, claims, damages or liabilities (or actions in respect
   thereof) in such proportion as is appropriate to reflect the relative
   benefits received by the Company on the one hand and the Underwriters
   on the other from the offering of the Shares.  If, however, the
   allocation provided by the immediately preceding sentence is not
   permitted by applicable law or if the indemnified party failed to give
   the notice required under subsection (c) above, then each indemnifying

                                     19<PAGE>





   party shall contribute to such amount paid or payable by such
   indemnified party in such proportion as is appropriate to reflect not
   only such relative benefits but also the relative fault of the Company
   on the one hand and the Underwriters on the other in connection with
   the statements or omissions which resulted in such losses, claims,
   damages or liabilities (or actions in respect thereof), as well as any
   other relevant equitable considerations.  The relative benefits
   received by the Company on the one hand and the Underwriters on the
   other shall be deemed to be in the same proportion as the total net
   proceeds from the offering (before deducting expenses) received by the
   Company bear to the total underwriting discounts and commissions
   (before deducting expenses) received by the Underwriters, in each case
   as set forth in the table on the cover page of the Prospectus.  The
   relative fault shall be determined by reference to, among other
   things, whether the untrue or alleged untrue statement of a material
   fact or the omission or alleged omission to state a material fact
   relates to information supplied by the Company on the one hand or the
   Underwriters on the other and the parties' relative intent, knowledge,
   access to information and opportunity to correct or prevent such
   statement or omission.  The Company and the Underwriters agree that it
   would not be just and equitable if contributions pursuant to this
   subsection (d) were determined by pro rata allocation (even if the
   Underwriters were treated as one entity for such purpose) or by any
   other method of allocation which does not take account of the
   equitable considerations referred to above in this subsection (d). 
   The amount paid or payable by an indemnified party as a result of the
   losses, claims, damages or liabilities (or actions in respect thereof)
   referred to above in this subsection (d) shall be deemed to include
   any legal or other expenses reasonably incurred by such indemnified
   party in connection with investigating or defending any such action or
   claim.  Notwithstanding the provisions of this subsection (d), no
   Underwriter shall be required to contribute any amount in excess of
   the amount by which the total price at which the Shares underwritten
   by it and distributed to the public were offered to the public exceeds
   the amount of any damages which such Underwriter has otherwise been
   required to pay by reason of such untrue or alleged untrue statement
   or omission or alleged omission.  No person guilty of fraudulent
   misrepresentation (within the meaning of Section 11(f) of the Act)
   shall be entitled to contribution from any person who was not guilty
   of such fraudulent misrepresentation.  The Underwriters' obligations
   in this subsection (d) to contribute are several in proportion to
   their respective underwriting obligations and not joint.

                  (e)  The obligations of the Company under this Section
   8 shall be in addition to any liability which the Company may
   otherwise have and shall extend, upon the same terms and conditions,
   to each person, if any, who controls any Underwriter within the
   meaning of the Act; and the obligations of the Underwriters under this
   Section 8 shall be in addition to any liability which the respective
   Underwriters may otherwise have and shall extend, upon the same terms
   and conditions, to each officer and director of the Company and to


                                     20<PAGE>





   each person, if any, who controls the Company within the meaning of
   the Act.

             9.   (a)   If any Underwriter shall default in its
   obligation to purchase the Shares which it has agreed to purchase
   hereunder at a Time of Delivery, you may in your discretion arrange
   for you or another party or other parties to purchase such Shares on
   the terms contained herein.  If within ______________________ after
   such default by any Underwriter you do not arrange for the purchase of
   such Shares, then the Company shall be entitled to a further period of
   ______________________ within which to procure another party or other
   parties reasonably satisfactory to you to purchase such Shares on such
   terms.  In the event that, within the respective prescribed periods,
   you notify the Company that you have so arranged for the purchase of
   such Shares, or the Company notifies you that it has so arranged for
   the purchase of such Shares, you or the Company shall have the right
   to postpone such Time of Delivery for a period of not more than
   ______________________, in order to effect whatever changes may
   thereby be made necessary in the Registration Statement or the
   Prospectus, or in any other documents or arrangements, and the Company
   agrees to file promptly any amendments to the Registration Statement
   or the Prospectus which in your opinion may thereby be made necessary.
   The term "Underwriter" as used in this Agreement shall include any
   person substituted under this Section with like effect as if such
   person had originally been a party to this Agreement with respect to
   such Shares.

                  (b)  If, after giving effect to any arrangements for
   the purchase of the Shares of a defaulting Underwriter or Underwriters
   by you and the Company as provided in subsection (a) above, the
   aggregate number of such Shares which remains unpurchased does not
   exceed ______________________ of the aggregate number of all the
   Shares to be purchased at such Time of Delivery, then the Company
   shall have the right to require each non-defaulting Underwriter to
   purchase the number of shares which such Underwriter agreed to
   purchase hereunder at such Time of Delivery and, in addition, to
   require each non-defaulting Underwriter to purchase its pro rata share
   (based on the number of Shares which such Underwriter agreed to
   purchase hereunder) of the Shares of such defaulting Underwriter or
   Underwriters for which such arrangements have not been made; but
   nothing herein shall relieve a defaulting Underwriter from liability
   for its default.

                  (c)  If, after giving effect to any arrangements for
   the purchase of the Shares of a defaulting Underwriter or Underwriters
   by you and the Company as provided in subsection (a) above, the
   aggregate number of such Shares which remains unpurchased exceeds
   _______________ of the aggregate number of all the Shares to be
   purchased at such Time of Delivery, or if the Company shall not
   exercise the right described in subsection (b) above to require
   non-defaulting Underwriters to purchase Shares of a defaulting
   Underwriter or Underwriters, then this Agreement (or, with respect to

                                     21<PAGE>





   the Second Time of Delivery, the obligations of the Underwriters to
   purchase and of the Company to sell the Optional Shares) shall
   thereupon terminate, without liability on the part of any
   non-defaulting Underwriter or the Company, except for the expenses to
   be borne by the Company and the Underwriters as provided in Section 6
   hereof and the indemnity and contribution agreements in Section 8
   hereof; but nothing herein shall relieve a defaulting Underwriter from
   liability for its default.

             10.  The respective indemnities, agreements,
   representations, warranties and other statements of the Company and
   the several Underwriters, as set forth in this Agreement or made by or
   on behalf of them, respectively, pursuant to this Agreement, shall
   remain in full force and effect, regardless of any investigation (or
   any statement as to the results thereof) made by or on behalf of any
   Underwriter or any controlling person of any Underwriter, or the
   Company, or any officer or director or controlling person of the
   Company, and shall survive delivery of and payment for the Shares.

        Anything herein to the contrary notwithstanding, the indemnity
   agreement of the Company in subsection (a) of Section 8 hereof, the
   representations and warranties in subsections (b), (c) and (d) of
   Section 1 hereof and any representation or warranty as to the accuracy
   of the Registration Statement or the Prospectus contained in any
   certificate furnished by the Company pursuant to Section 7 hereof,
   insofar as they may constitute a basis for indemnification for
   liabilities (other than payment by the Company of expenses incurred or
   paid in the successful defense of any action, suit or proceeding)
   arising under the Act, shall not extend to the extent of any interest
   therein of a controlling person or partner of an Underwriter who is a
   director, officer or controlling person of the Company when the
   Registration Statement has become effective, except in each case to
   the extent that an interest of such character shall have been
   determined by a court of appropriate jurisdiction as not against
   public policy as expressed in the Act.  Unless in the opinion of
   counsel for the Company the matter has been settled by controlling
   precedent, the Company will, if a claim for such indemnification is
   asserted, submit to a court of appropriate jurisdiction the question
   of whether such interest is against public policy as expressed in the
   Act and will be governed by the final adjudication of such issue.

             11.  If this Agreement shall be terminated pursuant to
   Section 9 hereof, the Company shall not then be under any liability to
   any Underwriter except as provided in Sections 6 and 8 hereof; but, if
   for any other reason, any Shares are not delivered by or on behalf of
   the Company as provided herein, the Company will reimburse the
   Underwriters through you for all out-of-pocket expenses approved in
   writing by you, including fees and disbursements of counsel,
   reasonably incurred by the Underwriters in making preparations for the
   purchase, sale and delivery of the Shares not so delivered, but the
   Company shall then be under no further liability to any Underwriter
   except as provided in Sections 6 and 8 hereof.

                                     22<PAGE>





             12.  In all dealings hereunder, you shall act on behalf of
   each of the Underwriters, and the parties hereto shall be entitled to
   act and rely upon any statement, request, notice or agreement on
   behalf of any Underwriter made or given by you jointly or by
   ___________________ on behalf of you as the representatives.

        All statements, requests, notices and agreements hereunder shall
   be in writing, and if to the Underwriters shall be delivered or sent
   by mail, telex or facsimile transmission to you as the representatives
   in care of ____________________________________; and if to the Company
   shall be delivered or sent by mail to the address of the Company set
   forth in the Registration Statement, Attention: Secretary; provided,
   however, that any notice to an Underwriter pursuant to Section 8(c)
   hereof shall be delivered or sent by mail, telex or facsimile
   transmission to such Underwriter at its address set forth in its
   Underwriters' Questionnaire, or telex constituting such Questionnaire,
   which address will be supplied to the Company by you upon request. 
   Any such statements, requests, notices or agreements shall take effect
   upon receipt thereof.

             13.  This Agreement shall be binding upon, and inure solely
   to the benefit of, the Underwriters, the Company and, to the extent
   provided in Sections 8 and 10 hereof, the officers and directors of
   the Company and each person who controls the Company or any
   Underwriter, and their respective heirs, executors, administrators,
   successors and assigns, and no other person shall acquire or have any
   right under or by virtue of this Agreement. No purchaser of any of the
   Shares from any Underwriter shall be deemed a successor or assign by
   reason merely of such purchase.

             14.  All references herein to a "subsidiary" of a
   corporation shall mean each corporation, limited liability company,
   partnership or other entity in which such corporation beneficially
   owns, directly or indirectly, capital stock or other equity interests
   representing in the aggregate 50% or more of the total combined voting
   power of such entity.

             15.  Time shall be of the essence of this Agreement.  As
   used herein, the term "business day" shall mean any day when the
   Commission's office in Washington, D.C.  is open for business.

             16.   THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
   ACCORDANCE WITH THE LAWS OF THE STATE OF _____________.

             17.  This Agreement may be executed by any one or more of
   the parties hereto in any number of counterparts, each of which shall
   be deemed to be an original, but all such counterparts shall together
   constitute one and the same instrument.

        If the foregoing is in accordance with your understanding, please
   sign and return to us five counterparts hereof, and upon the
   acceptance hereof by you, on behalf of each of the Underwriters, this

                                     23<PAGE>





   letter and such acceptance hereof shall constitute a binding agreement
   between each of the Underwriters and the Company. It is understood
   that your acceptance of this letter on behalf of each of the
   Underwriters is pursuant to the authority set forth in a form of
   Agreement among Underwriters, the form of which shall be submitted to
   the Company for examination upon request, but without warranty on your
   part as to the authority of the signers thereof.

                                      Very truly yours,

                                      AAR CORP.

        Termination Date shall be repaid in full on the Revolving Credit
        Termination Date (it being understood and agreed that, subject to
        the terms and conditions of this Agreement, the Borrower shall be
        entitled to make a final borrowing of one or more Advances
        pursuant to Section 2.1(a) on the Revolving Credit Termination
        Date).

             (c)  If on the last day of any calendar month, it is
        determined by the Lender that the sum of the aggregate amount of
        all outstanding Advances plus the aggregate Stated Amount of all
        issued and outstanding Letters of Credit exceeds the Commitment
        then in effect, the Borrower shall, immediately upon the first to
        occur of the Borrower becoming aware of such excess or notice
        thereof by the Lender, make a repayment (in U.S. Dollars) of the
        outstanding Advances in an amount which is at least sufficient to
        eliminate such excess.

             (d)  The Revolving Credit Termination Balance shall be
        payable in twenty (20) equal, consecutive quarterly installments,
        commencing on the first Payment Date following the Revolving
        Credit Termination Date.

             (e)  Any outstanding Advances and all other unpaid
        Obligations shall be paid in full by the Borrower on the Facility
        Termination Date.

                                     -12-<PAGE>





        2.4. FEES.  The Borrower further agrees to pay to the Lender a
   commitment fee of .30% (or if the Borrower no longer has an Investment
   Grade Classification .425%) per annum for the period from the date
   hereof to and including the Revolving Credit Termination Date on the
   average daily principal amount of the Commitment less the average
   daily principal amount of outstanding Advances.  All of the fees
   referred to in this Section 2.4 shall be payable quarterly in arrears
   within 15 days after receipt of a statement therefor from the Lender
   for such quarter, commencing with the calendar quarter ending December
   31, 1997.  The obligations of the Borrower under this Section 2.4
   shall survive the payment of the Advances and the termination of this
   Agreement.  In addition upon any HLT Classification, the Borrower
   agrees to pay the Lender upon demand, an HLT Classification fee equal
   to .125% of the Commitment in effect at the time of such HLT
   Classification.

        2.5. OPTIONAL REDUCTIONS IN COMMITMENT.  The Borrower may
   permanently reduce the Commitment in whole, or in part in integral
   multiples of $1,000,000, upon at least ten days' written notice to the
   Lender, which notice shall specify the amount of any such reduction;
   PROVIDED, HOWEVER, that the amount of the Commitment may not be
   reduced below the sum of the aggregate principal amount of the
   outstanding Advances plus the aggregate Stated Amount of all issued
   and outstanding Letters of Credit.  All accrued commitment fees shall
   be payable on the effective date of any termination of the obligations
   of the Lender to make Advances hereunder.

        2.6. [Intentionally Omitted].

        2.7. TYPES OF ADVANCES.  The Advances may be Floating Rate
   Advances or Eurodollar Advances, or a combination thereof, selected by
   the Borrower in accordance with Sections 2.10 and 2.13.

        2.8. MINIMUM AMOUNT OF EACH ADVANCE.  Each Eurodollar Advance
   shall be in the minimum amount of $1,000,000 (and in multiples of
   $100,000 if in excess thereof), and each Floating Rate Advance shall
   be in the minimum amount of $500,000 (and in multiples of $100,000 if
   in excess thereof); PROVIDED, HOWEVER, that any Floating Rate Advance
   may be in the amount of the Commitment.

        2.9. OPTIONAL PRINCIPAL PAYMENTS.  The Borrower may from time to
   time pay, without penalty or premium, all outstanding Floating Rate
   Advances, or, in a minimum aggregate amount of $1,000,000 or any
   integral multiple of $100,000 in excess thereof, any portion of the
   outstanding Floating Rate Advances upon 5 days' prior notice to the
   Lender.  Eurodollar Advances may be paid in full prior to the last day
   of the applicable Interest Period, subject to compliance with Section
   3.4. Principal payments made after the Revolving Credit Termination
   Date shall be applied to the principal installments payable under
   Section 2.3(d) in the inverse order of maturity.



                                     -13-<PAGE>





        2.10.     METHOD OF SELECTING TYPES AND INTEREST PERIODS FOR NEW
   ADVANCES.  The Borrower shall select the Type and, in the case of each
   Eurodollar Advance, the Interest Period applicable to each new Advance
   from time to time.  The Borrower shall give the Lender irrevocable
   notice in substantially the form of Exhibit "C" hereto with
   appropriate insertions (a "Borrowing Notice") not later than 10:00
   a.m. (Chicago time) at least (a) one Business Day before the Borrowing
   Date of each Floating Rate Advance and (b) three Business Days before
   the Borrowing Date for each Eurodollar Advance, in each case
   specifying:

               (i)     the Borrowing Date of such Advance, which shall be
                       a Business Day, prior to or on the Revolving
                       Credit Termination Date,

              (ii)     the aggregate amount of such Advance,

             (iii)     the Type of Advance selected, and

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

        2.11.     [Intentionally Omitted].

        2.12.     [Intentionally Omitted].

        2.13.     CONVERSION AND CONTINUATION OF OUTSTANDING ADVANCES. 
   Outstanding Advances may be continued or converted into Advances of
   another Type as provided below in this Section 2.13.

        Each Floating Rate Advance shall continue as Floating Rate
   Advance unless and until such Floating Rate Advance is repaid pursuant
   to Section 2.9 or converted into a Eurodollar Advance pursuant to this
   Section 2.13.  Each Eurodollar Advance shall continue as a Eurodollar
   Advance until the end of its respective Interest Period, at which time
   such Eurodollar Advance shall be automatically converted into a
   Floating Rate Advance unless the Borrower shall have given the Lender
   a Eurodollar Conversion Notice requesting that, at the end of such
   Interest Period, such Eurodollar Advance be converted into a new
   Eurodollar Advance for a new Interest Period.  Subject to the terms of
   Section 2.8, the Borrower may from time to time elect to convert all
   or any part of any Floating Rate Advance into a Eurodollar Advance, or
   to convert all or any part of any Eurodollar Advance into a new
   Eurodollar Advance for a new Interest Period; PROVIDED, that any
   conversion of any existing Eurodollar Advance shall be made on, and
   only on, the last day of its respective Interest Period.  The Borrower
   shall give the Lender irrevocable notice (a "Eurodollar Conversion
   Notice") of each conversion of an outstanding Advance into a
   Eurodollar Advance not later than 10:00 a.m. (Chicago time) at least
   three Business Days prior to the date of the requested conversion,
   specifying:


                                     -14-<PAGE>





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

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

             (iii)     the amount and Interest Period applicable to each
                       Eurodollar Advance into which such Advance is to
                       be converted.

   Notwithstanding anything to the contrary contained in this Section
   2.13, no Advance may be converted into or continued as a Eurodollar
   Advance (a) at any time within 30 days of the Facility Termination
   Date or (b) when any Default or Unmatured Default has occurred and is
   continuing.

        2.14.     RESTRICTIONS ON INTEREST PERIODS.  No Interest Period
   may extend beyond a Payment Date on which principal of the Advances
   shall be payable unless outstanding principal of Floating Rate
   Advances and Eurodollar Advances with Interest Periods ending prior to
   said Payment Date and unused Commitment shall be at least equal to the
   amount so payable.  No Interest Period shall extend beyond the
   Facility Termination Date.  No more than ten (10) Interest Periods may
   be in effect at any one time.

        2.15.     CHANGES IN INTEREST RATE, ETC.  Changes in the rate of
   interest on that portion of any Advance maintained as a Floating Rate
   Advance will take effect simultaneously with each change in the
   Alternate Base Rate and each change in the Applicable Margin referred
   to in the definition "Floating Rate".  Each Eurodollar Advance shall
   bear interest from and including the first day of the Interest Period
   applicable thereto to (but not including) the last day of such
   Interest Period at the interest rate determined as applicable to such
   Eurodollar Advance, provided that the rate of interest on each
   Eurodollar Advance will change simultaneously with each change, during
   the applicable Interest Period, of the Applicable Margin referred to
   in the definition of "Eurodollar Rate".

        2.16.     RATES APPLICABLE AFTER DEFAULT.  During the continuance
   of a Default the Lender may, at its option, by notice to the Borrower,
   declare that (i) each Eurodollar Advance shall bear interest for the
   remainder of the applicable Interest Period at the rate otherwise
   applicable to such Interest Period plus 2% per annum and (ii) each
   Floating Rate Advance shall bear interest at a rate per annum equal to
   the Floating Rate otherwise applicable to the Floating Rate Advance
   plus 2%.

        2.17.     METHOD OF PAYMENT. (a) All payments of principal,
   interest and fees to be made by the Borrower hereunder or under the
   Note shall be made in U.S. Dollars, without setoff, deduction, or
   counterclaim, in immediately available funds to the Lender at the


                                     -15-<PAGE>





   Lender's address specified pursuant to Article XIII by noon (local
   time) on the date when due and shall be applied by the Lender. 

        (b)  [Intentionally Omitted].

        (c)  On or before the time a principal payment is made on any of
   the Advances, the Borrower shall inform the Lender as to the
   proportionate application of such payment among the Floating Rate
   Advances and the Eurodollar Advances.  In the absence of such
   instructions, the Lender shall apply such payment first to the
   outstanding Floating Rate Advances and then apply any remainder to the
   outstanding Eurodollar Advances; PROVIDED, that as between Eurodollar
   Advances, the Lender shall endeavor to make such application (not
   otherwise disadvantageous to the Lender) as will mitigate the
   Borrower's liability to the Lender under Section 3.4 as a consequence
   of such application.

        2.18.     [Intentionally Omitted].

        2.19.     [Intentionally Omitted].

        2.20.     NOTE; TELEPHONIC NOTICES.  The Lender shall, and is
   hereby authorized to, record the principal amount of the Advances and
   each repayment on the schedule attached to the Note (or to otherwise
   record the same in its usual practice); PROVIDED, HOWEVER, that the
   failure so to record shall not affect the Borrower's obligations in
   respect of such Advances.  The Borrower hereby authorizes the Lender
   to extend, convert or continue Advances and to transfer funds based on
   telephonic notices made by any person or persons the Lender in good
   faith believes to be acting on behalf of the Borrower.  The Borrower
   agrees to deliver promptly to the Lender a written confirmation, if
   such confirmation is requested by the Lender, of each telephonic
   notice signed by an Authorized Officer.  If the written confirmation
   differs in any material respect from the action taken by the Lender,
   the record of the Lender shall govern absent manifest error.

        2.21.     INTEREST PAYMENT DATES; INTEREST AND FEE BASIS. 
   Interest accrued on each Floating Rate Advance shall be payable on
   each Payment Date, commencing with the first such date to occur after
   the date hereof, on any date on which the Floating Rate Advance is
   prepaid, whether due to acceleration or otherwise, and at maturity. 
   Interest accrued on that portion of the outstanding principal amount
   of any Floating Rate Advance converted into a Eurodollar Advance on a
   day other than a Payment Date shall be payable on the date of
   conversion.  Interest accrued on each Eurodollar Advance shall be
   payable on the last day of its applicable Interest Period, on any date
   on which the Eurodollar Advance is prepaid, whether by acceleration or
   otherwise, and at maturity.  Interest accrued on each Eurodollar
   Advance having an Interest Period longer than three months shall also
   be payable on the last day of each three-month interval during such
   Interest Period.  Interest and fees shall be calculated for actual
   days elapsed on the basis of a 360-day year.  Interest shall be

                                     -16-<PAGE>





   payable for the day an Advance is made but not for the day of any
   payment on the amount paid if payment is received prior to noon (local
   time) at the place of payment.  If any payment of principal of or
   interest on an Advance shall become due on a day which is not a
   Business Day, such payment shall be made on the next succeeding
   Business Day (unless, in the case of any interest payment, such
   Business Day would be in the following month, in which case, such
   interest shall be paid on the last Business Day in the month when such
   interest payment is due) and, in the case of a principal payment, such
   extension of time shall be included in computing interest in
   connection with such payment.  After maturity of any installment,
   interest shall be payable on demand.

        2.23.     [Intentionally Omitted].

        2.24.     [Intentionally Omitted].

        2.25.     LETTERS OF CREDIT.  Subject to the terms and conditions
   of this Agreement (including, without limitation, the last sentence of
   SECTION 2.27) the Lender agrees to issue Letters of Credit for the
   account of the Borrower from the Effective Date to but not including
   the Revolving Credit Termination Date at such times as the Borrower
   may request; provided, however, that the Lender shall not be obligated
   to issue any Letter of Credit to the extent that (a) the sum of (i)
   the aggregate principal amount of all Advances, plus (ii) the
   aggregate Stated Amount of all outstanding Letters of Credit, would
   exceed the Commitment or (b) the aggregate Stated Amount of all
   outstanding Letters of Credit would exceed $5,000,000.

        2.26.     MANNER OF ISSUANCE.

             (a)  APPLICATIONS.  The Borrower shall deliver to the Lender
        (i) prior to 11:00 a.m., Chicago time, on the Borrowing Date of
        any Letter of Credit or the amendment effective date with respect
        to any amendment of an outstanding Letter of Credit, the Lender's
        standard Application and Agreement for Irrevocable Letter of
        Credit ("APPLICATION"), the current form of which is attached
        hereto as Exhibit "D" (with blanks filled in accordingly), or an
        application for amendment in a form acceptable to the Lender.

             (b)  AUTHORIZED OFFICERS.  Each Authorized Officer may
        execute and deliver an Application, and request a Letter of
        Credit or an amendment thereto (as applicable) on behalf of the
        Borrower.  The Lender shall be entitled to rely conclusively on
        each such Authorized Officer's authority to take the action
        referred to in the immediately preceding sentence until the
        Lender receives written notice from the Borrower to the contrary. 
        The Lender shall not have a duty to verify the authenticity of
        the signature appearing on any Application and the Lender shall
        have no duty to verify the identity of any Person representing

                                     -17-<PAGE>





        himself as one of the Authorized Officers entitled to take the
        aforesaid actions on behalf of the Borrower.

             (c)  NO LIABILITY.  The Lender shall not incur any liability
        to the Borrower in acting upon any request referred to above
        which the Lender believes in good faith to have been given by an
        Authorized Officer or for otherwise acting in accordance with
        this SECTION 2.26.

             (d)  APPLICATIONS IRREVOCABLE.  Each Application submitted
        pursuant to this SECTION 2.26 shall be irrevocable.

             (e)  ISSUANCE.  Subject to the terms and conditions set
        forth in SECTION 2.25, the Lender will issue the Letter of Credit
        for the account of the Borrower on the applicable Borrowing Date.

        2.27.     TERM.  Letters of Credit shall be stated to expire no
   more than one year from the date of issuance and may be renewed if so
   requested by the Borrower in the manner required by the Lender (but in
   any event such request shall be in writing, shall reasonably describe
   the Letter of Credit requested to be renewed and the requested renewal
   term and shall be given by an Authorized Officer to the Lender not
   less than 30 days prior to expiration of such Letter of Credit);
   PROVIDED, that no Letter of Credit shall be stated to expire on a date
   after the Revolving Credit Termination Date.  No such renewal shall be
   for more than one year.

        2.28.     LETTER OF CREDIT FEES.  The Borrower agrees to pay the
   Lender, on demand, the Lender's standard issuance, administrative,
   operating and other fees and charges in effect from time to time for
   issuing and administering any Letters of Credit.  It is acknowledged
   by the Lender that as of the date of this Agreement, the Lender shall
   charge the Borrower $200 as an issuance fee and $100 as an amendment
   or renewal fee. The Lender may change such fees at such times, in its
   sole discretion.  The Borrower further agrees to pay the Lender a
   commission on the undrawn amount of each Letter of Credit and on each
   draft drawn on the Lender pursuant to a Letter of Credit and accepted
   by the Lender in such amount(s) as may from time to time be
   established by the Lender.  It is acknowledged by the Lender that as
   of the date of this Agreement such commission shall be equal to 0.50%
   per annum (or at all times when the Borrower does not have an
   Investment Grade Rating, 1.00%). The Lender may change such
   commissions at such times, in its sole discretion.  Such commissions
   shall be paid at such frequency as the Lender shall determine.  The
   Lender may provide for the payment of any fees, charges or commission
   due, if not paid by the Borrower when due, by advancing the amount
   thereof to the Borrower as an Advance.

        2.29.     REIMBURSEMENT OBLIGATION.

             (a)  REIMBURSEMENT.  In the event that any amount is drawn
        under a Letter of Credit by the beneficiary thereof and the

                                     -18-<PAGE>





        Borrower shall not have reimbursed the Lender for such amount
        drawn immediately when due in accordance with the Application,
        the amount so paid shall be deemed to be an Advance.

             (b)  IRREVOCABLE OBLIGATION.  The obligation of the Borrower
        to make payment to the Lender with respect to Letters of Credit
        shall be unconditional and irrevocable and shall not be subject
        to any qualification or exception whatsoever and shall be made
        under all circumstances, including without limitation any of the
        following circumstances:

               (i)     Any lack of validity or enforceability of this
                       Agreement or any of the other Loan Documents;

              (ii)     The existence of any claim, setoff, defense or
                       other right which the Borrower may have at any
                       time against a beneficiary named in a Letter of
                       Credit or any transferee of any Letter of Credit
                       (or any Person for whom any such transferee may be
                       acting), the Lender or any other Person, whether
                       in connection with this Agreement, any other Loan
                       Document, the transactions contemplated herein or
                       any unrelated transactions (including any
                       underlying transactions between the Borrower and
                       the beneficiary named in any Letter of Credit);

             (iii)     Any draft, certificate or any other document
                       presented under the Letter of Credit proving to be
                       forged, fraudulent, invalid or insufficient in any
                       respect or in any statement therein being untrue
                       or inaccurate in any respect;

              (iv)     The surrender or impairment of any security for
                       the performance or observance of any of the terms
                       of any of the Loan Documents;

               (v)     The occurrence of any Default or Unmatured
                       Default, or termination of the Commitment or this
                       Agreement;

              (vi)     Any amendment, modification, waiver, consent or
                       any substitution, exchange or release of or
                       failure to perfect any interest in collateral
                       security, with respect to any Letter of Credit;

             (vii)     Any failure, omission, delay or lack on the part
                       of the Lender or any party to any of the Letters
                       of Credit to enforce, assert or exercise any
                       right, power or remedy conferred upon the Lender
                       or any such party under this Agreement or any
                       Letter of Credit, or any other acts or omissions
                       on the part of the Lender or any other party; and

                                     -19-<PAGE>





            (viii)     Any other event or circumstance that would, in the
                       absence of this clause, result in the release or
                       discharge by operation of law or otherwise of the
                       Borrower from the performance or observance of any
                       obligation, covenant or agreement contained in
                       this Section 2.29.

                           CHANGE IN CIRCUMSTANCES
                           -----------------------

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

             (i)  subjects the Lender to any tax, duty, charge or
        withholding on or from payments due from the Borrower (excluding
        federal taxation of the overall net income of the Lender), or
        changes the time of payment of such taxes or other amounts or the
        basis of taxation of payments to the Lender in respect of its
        Advances or other amounts due it hereunder, or

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

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

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

        3.2. CHANGES IN CAPITAL ADEQUACY REGULATIONS.  If the Lender
   determines the amount of capital required or expected to be maintained
   by the Lender or any corporation controlling the Lender is increased
   as a result of a Change, then, within 15 days of demand by the Lender,
   the Borrower shall pay the Lender the amount necessary to compensate
   for any shortfall in the rate of return on the portion of such
   increased capital which the Lender determines is attributable to this
   Agreement, the Advances or its obligation to make Advances hereunder

                                     -20-<PAGE>





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

        3.3. AVAILABILITY OF EURODOLLAR ADVANCES.  If (i) the Lender
   determines that maintenance of its Eurodollar Advances would violate
   any applicable treaty, law, rule, regulation, or directive, whether or
   not having the force of law, (ii) the Lender determines that deposits
   of a type and maturity appropriate to match fund Eurodollar Advances
   are not available, (iii) the Lender determines that the interest rate
   applicable to a Eurodollar Advance does not accurately reflect the
   cost of making or maintaining such Eurodollar Advance or (iv)
   reasonable means do not exist for the Lender to determine the
   Eurodollar Rate for the amount and maturity requested, then the Lender
   shall suspend the availability of any new Eurodollar Advances (whether
   pursuant to Section 2.10 or Section 2.13).

        3.4. FUNDING INDEMNIFICATION.  If any payment of a Eurodollar
   Advance occurs on a date prior to the last day of the applicable
   Interest Period, whether because of acceleration, prepayment or
   otherwise, or a Eurodollar Advance is not made on the date specified
   by the Borrower in its Borrowing Notice or Eurodollar Conversion
   Notice, as the case may be, as a consequence of any condition
   precedent to such Advance under Section 2.1 or Article IV not being
   satisfied, as a consequence of any failure by the Borrower to borrow
   such Advance when the same has been made available to it pursuant to
   Section 2.12 or as a consequence of a prohibition on making,
   maintaining or repaying the principal of a Eurodollar Advance, the
   Borrower will indemnify the Lender for any loss or cost in liquidating
   or employing deposits acquired to fund or maintain the Eurodollar
   Advance and, provided that the Lender has taken such reasonable
   action, if any, not disadvantageous to it, to mitigate the same, any
   other loss or cost incurred by the Lender resulting therefrom.

        3.5. LENDER STATEMENTS; SURVIVAL OF INDEMNITY.  The Lender shall
   deliver a written statement of the Lender as to the amount due, if
   any, under Section 2.18, 3.1, 3.2 or 3.4.  Such written statement
   shall set forth in reasonable detail (and in accordance with Agreement

                                     -21-<PAGE>





   Accounting Principles, where applicable) the calculations upon which
   the Lender determined such amount and shall be final, conclusive and
   binding on the Borrower in the absence of manifest error. 
   Determination of amounts payable under such Sections in connection
   with a Eurodollar Advance shall be calculated as though the Lender
   funded its Eurodollar Advance through the purchase of a deposit of the
   type and maturity corresponding to the deposit used as a reference in
   determining the Eurodollar Rate applicable to such Eurodollar Advance,
   whether in fact that is the case or not.  Unless otherwise provided
   herein, the amount specified in the written statement shall be payable
   on demand after receipt by the Borrower of the written statement.  The
   obligations of the Borrower under Sections 2.18, 3.1, 3.2 and 3.4
   shall survive payment of the obligations and termination of this
   Agreement.

        3.6. REFUND TO BORROWER.  If, and to the extent that, the Lender
   shall actually receive a credit against its United States federal
   income tax liability or otherwise receive any rebate or refund from
   any government or governmental agency in respect of any amount paid by
   the Borrower pursuant to Section 3.1 or Section 3.2, the Lender agrees
   to promptly notify the Borrower thereof and make reimbursement of
   credit, rebate or refund to the Borrower, provided that if the Lender
   reasonably believes that such credit, rebate or refund may be subject
   to challenge, then the Lender shall thereupon enter into negotiations
   in good faith with the Borrower to determine when reimbursement of
   such credit, rebate or refund can be made to the Borrower.

        The Borrower represents and warrants to the Lender that:



                                     -23-<PAGE>





        5.1. CORPORATE EXISTENCE AND STANDING.  Each of the Borrower and
   its Subsidiaries is a corporation duly incorporated, validly existing
   and in good standing under the laws of its jurisdiction of
   incorporation and has all requisite authority to conduct its business
   in each jurisdiction in which its business is conducted.

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

        5.3. NO CONFLICT; GOVERNMENT CONSENT.  Neither the execution and
   delivery by the Borrower of the Loan Documents, nor the consummation
   of the transactions therein contemplated, nor compliance with the
   provisions thereof will violate any law, rule, regulation, order,
   writ, judgment, injunction, decree or award binding on the Borrower or
   any of its Subsidiaries or the Borrower's or any Subsidiary's articles
   of incorporation or by-laws or the provisions of any indenture,
   instrument or agreement to which the Borrower or any of its
   Subsidiaries is a party or is subject, or by which it, or its
   property, is bound, or conflict with or constitute a default
   thereunder, or result in the creation or imposition of any Lien in, of
   or on the property of the Borrower or a Subsidiary pursuant to the
   terms of any such indenture, instrument or agreement.  No order,
   consent, approval, license, authorization, or validation of, or
   filing, recording or registration with, or exemption by, any
   governmental or public body or authority, or any subdivision thereof,
   is required to authorize, or is required in connection with the
   execution, delivery and performance of, or the legality, validity,
   binding effect or enforceability of, any of the Loan Documents.

        5.4. FINANCIAL STATEMENTS.  The August 31, 1997 consolidated
   financial statements of the Borrower and its Subsidiaries heretofore
   delivered to the Lenders were prepared in accordance with generally
   accepted accounting principles in effect on the date such statements
   were prepared and fairly present the consolidated financial condition
   and operations of the Borrower and its Subsidiaries at such date and
   the consolidated results of their operations for the period then
   ended.

        5.5. MATERIAL ADVERSE CHANGE.  Since August 31, 1997, there has
   been no change in the business, properties, prospects, condition
   (financial or otherwise) or results of operations of the Borrower and
   its Subsidiaries which could reasonably be expected to have a Material
   Adverse Effect.


                                     -24-<PAGE>





        5.6. TAXES.  The Borrower and its Subsidiaries have filed all
   United States federal tax returns and all other tax returns which are
   required to be filed and have paid all taxes due pursuant to said
   returns or pursuant to any assessment received by the Borrower or any
   of its Subsidiaries, except for the filing of such returns and the
   payment of such taxes, if any, as (a) are being contested in good
   faith and as to which adequate reserves have been provided or (b) do
   not in the aggregate exceed $4,000,000 and the failure to file or pay
   for which could not reasonably be expected to have a Material Adverse
   Effect.  As of the date hereof, the United States income tax returns
   of the Borrower and its Subsidiaries have been audited by the Internal
   Revenue Service through the fiscal year ended 1997.  No tax liens have
   been filed other than those permitted pursuant to Section 6.16(a). 
   The charges, accruals and reserves on the books of the Borrower and
   its Subsidiaries in respect of any taxes or other governmental charges
   are adequate.

        5.7. LITIGATION AND CONTINGENT OBLIGATIONS.  Except as set forth
   in the Borrower's Form 10-K filed with the Securities and Exchange
   Commission for its fiscal year ended May 31, 1997, there is no
   litigation, arbitration, governmental investigation, proceeding or
   inquiry pending or, to the knowledge of any of their officers,
   threatened against or affecting the Borrower or any of its
   Subsidiaries which could reasonably be expected to have a Material
   Adverse Effect.  Other than any liability incident to such litigation,
   arbitration or proceedings, the Borrower has no material contingent
   obligations not provided for or disclosed in the Borrower's Form 10-K
   filed with the Securities and Exchange Commission for its fiscal year
   ended May 31, 1997.

        5.8. SUBSIDIARIES.  As of the date hereof, Borrower's Form 10-K
   filed with the Securities and Exchange Commission for its fiscal year
   ended May 31, 1997 contains an accurate description of all of the
   Borrower's presently existing Significant Subsidiaries (as defined in
   Regulation S-X of the Securities and Exchange Commission).  All of the
   issued and outstanding shares of capital stock of all of the
   Borrower's Subsidiaries have been duly authorized and issued and are
   fully paid and non-assessable.

        5.9. ERISA.  The Unfunded Liabilities of all Single Employer
   Plans do not in the aggregate exceed $10,000,000.  Neither the
   Borrower nor any other member of the Controlled Group has incurred, or
   is reasonably expected to incur any withdrawal liability to
   Multiemployer Plans in an aggregate amount which, when added to the
   aggregate Unfunded Liabilities of all Single Employer Plans, would
   exceed of $10,000,000.  Each Plan complies in all material respects
   with all applicable requirements of law and regulations and no
   Reportable Event has occurred with respect to any Plan.  Neither the
   Borrower nor any other member of the Controlled Group has withdrawn
   from any Plan or initiated steps to do so, and no steps have been
   taken to reorganize or terminate any Plan.


                                     -25-<PAGE>





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

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

        5.12.     COMPLIANCE WITH LAWS.  The Borrower and its
   Subsidiaries have complied in all respects with all applicable
   statutes, rules, regulations, orders and restrictions of any domestic
   or foreign government or any instrumentality or agency thereof, having
   jurisdiction over the conduct of their respective businesses or the
   ownership of their respective properties, except where failure to
   comply would not reasonably be expected to have a Material Adverse
   Effect.  Neither the Borrower nor any Subsidiary has received any
   notice to the effect that its operations are not in material
   compliance with any of the requirements of applicable federal, state
   and local environmental, health and safety statutes and regulations or
   the subject of any federal or state investigation evaluating whether
   any remedial action is needed to respond to a release of any toxic or
   hazardous waste or substance into the environment, which
   non-compliance or remedial action could reasonably be expected to have
   a Material Adverse Effect.

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


                                 ARTICLE VI

                  specifically set forth in the audit report for such
                  fiscal year delivered to the Lender pursuant to clause

                                ARTICLE VIII

               ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES
               ----------------------------------------------

        8.1. ACCELERATION.  If any Default described in Section 7.6 or
   7.7 occurs with respect to the Borrower, the obligations of the Lender
   to make Advances and to issue Letters of Credit hereunder shall
   automatically terminate and the Obligations shall immediately become
   due and payable without any election or action on the part of the
   Lender.  If any other Default occurs, the Lender may terminate or
   suspend the obligations of the Lender to make Advances and to issue
   Letters of Credit hereunder, or by written notice to the Borrower
   declare the Obligations to be due and payable, or both, whereupon the
   Obligations shall become immediately due and payable, without
   presentment, demand, protest or further notice of any kind, all of
   which the Borrower hereby expressly waives.  The Lender agrees to give
   the Borrower prompt subsequent notice of any termination or suspension
   of the obligations of the Lender to make Advances and to issue Letters
   of Credit hereunder; PROVIDED, that the giving of such notice shall
   not be a condition to the effectiveness of any such termination or
   suspension.

        8.2. AMENDMENTS.  The provisions of this Agreement and of each
   other Loan Document may from time to time be amended, modified or
   waived, if such amendment, modification or waiver is in writing and
   consented to by the Borrower and the Lender.

        8.3. PRESERVATION OF RIGHTS; WAIVERS, ETC.  No delay or omission
   of the Lender to exercise any right under the Loan Documents shall
   impair such right or be construed to be a waiver of any Default or an
   acquiescence therein, and the making of an Advance or issuance of a
   Letter of Credit notwithstanding the existence of a Default or the
   inability of the Borrower to satisfy the conditions precedent to such
   Advance or issuance of a Letter of Credit shall not constitute any
   waiver or acquiescence.  Any single or partial exercise of any such
   right shall not preclude other or further exercise thereof or the
   exercise of any other right, and no waiver, amendment or other
   variation of the terms, conditions or provisions of the Loan Documents
   whatsoever shall be valid unless in writing signed by the Lender, and
   then only to the extent in such writing specifically set forth.  All
   remedies contained in the Loan Documents or by law afforded shall be
   cumulative and all shall be available to the Lender until the
   Obligations have been paid in full.

   respect of the Loan Documents shall be paid by the Borrower, together
   with interest and penalties, if any.

        9.4. HEADINGS.  Section headings in the Loan Documents are for

   of any of the provisions of the Loan Documents.

        9.5. ENTIRE AGREEMENT.  The Loan Documents embody the entire

   supersede all prior agreements and understandings between the Borrower
   and the Lender relating to the subject matter thereof.

   construed so as to confer any right or benefit upon any Person other

   assigns.

        9.7. EXPENSES; INDEMNIFICATION.  The Borrower shall reimburse the
   Lender for any and all reasonable costs and out-of-pocket expenses
   (including attorneys' fees and time charges of attorneys for the

   negotiation, execution, delivery, review, amendment, modification, and
   administration of the Loan Documents.  The Borrower also agrees to
   reimburse the Lender for any and all reasonable costs and
   out-of-pocket expenses (including attorneys' fees and time charges of
   attorneys for the Lender, which attorneys may be employees of the
   Lender) paid or incurred by the Lender in connection with the
   collection and enforcement of the Loan Documents.  The Borrower
   further agrees to indemnify the Lender, its directors, officers and
   employees against all losses, claims, damages, penalties, judgments,
   liabilities and expenses (including, without limitation, all expenses
   of litigation or preparation therefor whether or not the Lender is a

                                     -41-<PAGE>





   party thereto) which any of them may pay or incur arising out of any
   term or condition contained in this Agreement or the other Loan
   Documents, or the direct or indirect application or proposed
   application of the proceeds of any Advance or Letter of Credit
   hereunder, except to the extent any of the foregoing arises solely

   indemnification.  The obligations of the Borrower under this Section
   shall survive the termination of this Agreement.

        9.8. [Intentionally Omitted].

        9.9. ACCOUNTING.  Except as provided to the contrary herein, all
   accounting terms used herein shall be interpreted and all accounting

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

        9.11.     NONLIABILITY OF THE LENDER.  The relationship between
   the Borrower and the Lender shall be solely that of borrower and
   lender.  The Lender shall not have any fiduciary responsibilities to
   the Borrower.  The Lender does not undertake any responsibility to the
   Borrower to review or inform the Borrower of any matter in connection
   with any phase of the Borrower's business or operations.

        9.12.     CHOICE OF LAW.  THE LOAN DOCUMENTS (OTHER THAN THOSE
   CONTAINING A CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE

   CONFLICTS) OF THE STATE OF ILLINOIS, BUT GIVING EFFECT TO FEDERAL LAWS
   APPLICABLE TO NATIONAL BANKS.

        9.13.     CONSENT TO JURISDICTION.  THE BORROWER AND THE LENDER
   EACH HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF
   ANY UNITED STATES FEDERAL OR ILLINOIS STATE COURT SITTING IN CHICAGO
   IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY LOAN

   OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH
   SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT
   IS AN INCONVENIENT FORUM.  NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE
   BORROWER TO BRING PROCEEDINGS AGAINST THE LENDER, OR THE RIGHT OF THE
   LENDER TO BRING PROCEEDINGS AGAINST THE BORROWER, IN THE COURTS OF ANY
   OTHER JURISDICTION.


                                     -42-<PAGE>





        9.14.     CONFIDENTIALITY.  The Lender agrees to use any

   ANY LOAN DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER.

        11.1.     SETOFF.  In addition to, and without limitation of, any
   rights of the Lender under applicable law, so long as any Default has
   occurred and is continuing, any indebtedness from the Lender to the
   Borrower (including all account balances, whether provisional or final
   and whether or not collected or available) may be offset and applied
   toward the payment of the Obligations then due and owing to the
   Lender.

        12.1.     SUCCESSORS AND ASSIGNS.  The terms and provisions of
   the Loan Documents shall be binding upon and inure to the benefit of
   the Borrower and the Lender and their respective successors and

                                     -43-<PAGE>





   assigns, except that (i) the Borrower shall not have the right to
   assign its rights or obligations under the Loan Documents and (ii) any
   assignment by the Lender must be made in compliance with Section 12.3.
   Notwithstanding clause (ii) of this Section, the Lender may at any
   time, without the consent of the Borrower, assign all or any portion
   of its rights under this Agreement and the Note to a Federal Reserve
   Bank; provided, however, that no such assignment shall release the
   transferor Lender from its obligations hereunder.  Any assignee or
   transferee of the Note agrees by acceptance thereof to be bound by all
   the terms and provisions of the Loan Documents.  Any request,
   authority or consent of any Person, who at the time of making such
   request or giving such authority or consent is the holder of the Note,
   shall be conclusive and binding on any subsequent holder, transferee
   or assignee of the Note or of any Note or Notes issued in exchange
   therefor.

        12.2.     PARTICIPATIONS.

             12.2.1.   PERMITTED PARTICIPANTS; EFFECT.  The Lender may,
        in the ordinary course of its business and in accordance with
        applicable law, at any time sell to one or more banks or other
        entities ("Participants") participating interests in any Advance,
        any Letter of Credit, the Note, the Commitment or any other
        interest of the Lender under the Loan Documents.  The Lender
        selling such participating interests to a Participant agrees to
        promptly notify the Borrower of such sale and the identity of
        such Participant.  In the event of any such sale by the Lender of
        participating interests to a Participant, the Lender's
        obligations under the Loan Documents shall remain unchanged, the
        Lender shall remain solely responsible for the performance of
        such obligations, the Lender shall remain the holder of the Note
        for all purposes under the Loan Documents, and the Borrower shall
        continue to deal solely and directly with the Lender in
        connection with the Lender's rights and obligations under the
        Loan Documents.

             12.2.2.   VOTING RIGHTS.  The Lender shall retain the sole
        right to approve, without the consent of any Participant, any
        amendment, modification or waiver of any provision of the Loan
        Documents other than any amendment, modification or waiver with
        respect to any Advance, Letter of Credit or Commitment in which
        such Participant has an interest which forgives principal,
        interest or fees or reduces the interest rate or fees payable
        with respect to any such Advance, Letter of Credit or Commitment,
        postpones any date fixed for any regularly-scheduled payment of
        principal of, or interest or fees on, any such Advance, Letter of
        Credit or Commitment, releases any guarantor of any such Advance
        or Letter of Credit or releases any substantial portion of
        collateral, if any, securing any such Advance or Letter of
        Credit.



                                     -44-<PAGE>





             12.2.3.   BENEFIT OF SETOFF.  The Borrower agrees that each
        Participant shall be deemed to have the right of setoff provided
        in Section 11.1 in respect of its participating interest in
        amounts owing under the Loan Documents to the same extent as if
        the amount of its participating interest were owing directly to
        it as the Lender under the Loan Documents.

        12.3.     ASSIGNMENTS.

             12.3.1.   PERMITTED ASSIGNMENTS.  The Lender may, in the
        ordinary course of its business and in accordance with applicable
        law, at any time assign to one or more banks or other entities
        ("Purchasers") all or any part of its rights and obligations
        under the Loan Documents.  Unless a Default has occurred and is
        continuing, the consent of the Borrower shall be required prior
        to an assignment becoming effective with respect to a Purchaser
        which is not an Affiliate of the Lender.

             12.3.2.   [Intentionally Omitted].

        12.4.     DISSEMINATION OF INFORMATION.  The Borrower authorizes
   the Lender to disclose to any Participant or Purchaser or any other
   Person acquiring an interest in the Loan Documents by operation of law
   (each a "Transferee") and any prospective Transferee any and all
   information in the Lender's possession concerning the creditworthiness
   of the Borrower and its Subsidiaries; provided that each Transferee
   and prospective Transferee agrees in writing for the benefit of the
   Borrower to be bound by Section 9.14.

   The Northern Trust Company
   50 S. LaSalle Street
   Chicago, Illinois 60675


   Gentlemen/Ladies:

        We are counsel for AAR Corp., a Delaware corporation (the
   "Borrower"), and have represented the Borrower in connection with its
   execution and delivery of a Credit Agreement dated as of November 1,
   1997 between the Borrower and The Northern Trust Company (the
   "Lender"), providing for Advances in an aggregate principal amount not
   exceeding $10,000,000 at any one time outstanding (the "Agreement"). 
   All capitalized terms used in this opinion and not otherwise defined
   shall have the meanings attributed to them in the Agreement.

        We have examined the Borrower's articles of incorporation,
   by-laws, resolutions, the Loan Documents and such other matters of
   fact and law which we deem necessary in order to render this opinion. 
   Based upon the foregoing, it is our opinion that:

        1.   The Borrower and each Subsidiary are corporations duly
   incorporated, validly existing and in good standing under the laws of
   their states of incorporation and have all requisite authority to
   conduct their business in each jurisdiction in which their business is
   conducted.

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

             (a)  require any consent of the Borrower's shareholders;

             (b)  violate any law, rule, regulation, order, writ,
        judgment, injunction, decree or award binding on the Borrower or
        any of its Subsidiaries or the Borrower's or any Subsidiary's
        articles of incorporation or by-laws or any indenture, instrument
        or agreement binding upon the Borrower or any of its
        Subsidiaries; or

             (c)  result in, or require, the creation or imposition of
        any Lien pursuant to the provisions of any indenture, instrument
        or agreement binding upon the Borrower or any of its
        Subsidiaries.

        3.   The Loan Documents have been duly executed and delivered by
   the Borrower and constitute legal, valid and binding obligations of<PAGE>





   the Borrower enforceable in accordance with their terms except to the
   extent the enforcement thereof may be limited by bankruptcy,
   insolvency or similar laws affecting the enforcement of creditors,
   rights generally and subject also to the availability of equitable
   remedies if equitable remedies are sought.

        4.   Except as set forth in the Borrower's Form 10-K filed with
   the Securities and Exchange Commission for its fiscal year ended May
   31, 1997, there is no litigation or proceeding against the Borrower or
   any of its Subsidiaries which, if adversely determined, could have a
   Material Adverse Effect.

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


        This opinion may be relied upon by the Lender and its
   participants, assignees and other transferees. 



                                 Very truly yours,


                                 ___________________________________

                                 ARTICLE II

                     FORM OF RECEIPTS; DEPOSIT OF STOCK;
                      EXECUTION AND DELIVERY, TRANSFER,
                    SURRENDER AND REDEMPTION OF RECEIPTS

        SECTION 2.01.  Form and Transfer of Receipts.  Definitive
   Receipts shall be printed, lithographed, typewritten, mimeographed or
   engraved or otherwise reproduced in any manner and shall be
   substantially in the form set forth in Exhibit A annexed to this
   Deposit Agreement, with appropriate insertions, omissions,
   substitutions and other variations as are required or permitted by
   this Agreement.  As set forth in Section 2.09, all or a portion of the
   Definitive Receipts may be represented by one or more book-entry
   receipts (each, a "Book-Entry Receipt").  Pending the preparation of
   definitive Receipts, the Depositary, upon the written order of the
   Company delivered in compliance with Section 2.02, shall execute and
   deliver temporary Receipts which are printed, lithographed,
   typewritten, mimeographed or otherwise substantially of the tenor of
   the definitive Receipts in lieu of which they are issued and with such
   appropriate insertions, omissions, substitutions and other variations
   as the persons executing such Receipts may determine, as evidenced by
   their execution of such Receipts.  If temporary Receipts are issued,
   the Company and the Depositary will cause definitive Receipts to be
   prepared without unreasonable delay.  After the preparation of
   definitive Receipts, the temporary Receipts shall be exchangeable for
   definitive Receipts upon surrender of the temporary Receipts at an
   office described in the third paragraph of Section 2.02, without
   charge to the holder.  Upon surrender for cancellation of any one or
   more temporary Receipts, the Depositary shall execute and deliver in
   exchange therefor definitive Receipts representing the same number of
   Depositary Shares as represented by the surrendered temporary Receipt
   or Receipts.  Such exchange shall be made at the Company's expense and
   without any charge therefor. Until so exchanged, the temporary
   Receipts shall in all respects be entitled to the same benefits under
   this Deposit Agreement, and with respect to the Stock, as definitive
   Receipts.


                                      2<PAGE>





        Receipts shall be executed by the Depositary by the manual
   signature of a duly authorized officer of the Depositary; provided,
   that such signature may be a facsimile if a Registrar for the Receipts
   (other than the Depositary) shall have been appointed and such
   Receipts are countersigned by manual signature of a duly authorized
   officer of the Registrar.  No Receipt shall be entitled to any
   benefits under this Deposit Agreement or be valid or obligatory for
   any purpose unless it shall have been executed manually by a duly
   authorized officer of the Depositary or, if a Registrar for the
   Receipts (other than the Depositary) shall have been appointed, by
   facsimile signature of a duly authorized officer of the Depositary and
   countersigned manually by a duly authorized officer of such Registrar. 
   The Depositary shall record on its books each Receipt so signed and
   delivered as hereinafter provided. 

        Receipts may be endorsed with or have incorporated in the text
   thereof such legends or recitals or changes not inconsistent with the
   provisions of this Deposit Agreement as may be required by the Company
   or the Depositary or required to comply with any applicable law or any
   regulation thereunder or with the rules and regulations of any
   securities exchange upon which the Stock, the Depositary Shares or the
   Receipts may be listed or to conform with any usage with respect
   thereto, or to indicate any special limitations or restrictions to
   which any particular Receipts are subject.

        Subject to any limitations set forth in a Receipt or in this
   Deposit Agreement title to Depositary Shares evidenced by a Receipt
   which is properly endorsed or accompanied by a properly executed
   instrument of transfer shall be transferable by delivery with the same
   effect as in the case of a negotiable instrument; provided, however,
   that until transfer of a Depositary Share shall be registered on the
   books of the Depositary as provided in Section 2.04, the Depositary
   may, notwithstanding any notice to the contrary, treat the Record
   Holder thereof at such time as the absolute owner thereof for the
   purpose of determining the person entitled to distributions of
   dividends or other distributions with respect to the Stock or to any
   notice provided for in this Deposit Agreement and for all other
   purposes.

   The Depositary shall not lend any Stock deposited hereunder. 

        SECTION 2.02.  Deposit of Stock; Execution and Delivery of
   Receipts in Respect Thereof.  Subject to the terms and conditions of
   this Deposit Agreement, the Company may from time to time deposit
   shares of Stock under this Deposit Agreement by delivery to the
   Depositary of a certificate or certificates representing the Stock to
   be deposited.  Such certificate or certificates representing the Stock
   shall be properly endorsed or accompanied, if required by the
   Depositary, by a duly executed instrument of transfer or endorsement,
   in form satisfactory to the Depositary, together with all such
   certifications as may be required by the Depositary in accordance with
   the provisions of this Deposit Agreement, and together with a written

                                      3<PAGE>





   order of the Company directing the Depositary to execute and deliver
   to, or upon the written order of, the person or persons stated in such
   order a Receipt or Receipts for the number of Depositary Shares
   relating to such deposited Stock.

        All Stock deposited by the Company with the Depositary shall be
   held by the Depositary at the Depositary's Office or at such other
   place or places as the Depositary shall determine.

        Upon receipt by the Depositary of a certificate or certificates
   representing the Stock deposited in accordance with the provisions of
   this Section, together with the other documents required as above
   specified, and upon recordation of the Stock so deposited on the books
   of the Company in the name of the Depositary or its nominee, the
   Depositary, subject to the terms and conditions of this Deposit
   Agreement, shall execute and deliver, to or upon the order of the
   person or persons named in the written order delivered to the
   Depositary referred to in the first paragraph of this Section, a
   Receipt or Receipts for the number of Depositary Shares relating to
   the Stock so deposited and registered in such name or names as may be
   requested by such person or persons.  The Depositary shall execute and
   deliver such Receipt or Receipts at the Depositary's Office or such
   other offices, if any, as the Depositary may designate.  Delivery at
   other offices shall be at the risk and expense of the person
   requesting such delivery.

        Other than in the case of splits, combinations or other
   reclassifications affecting the Stock, or in the case of dividends or
   other distributions of Stock, if any, there shall be deposited
   hereunder not more than ______ shares of Stock.

        SECTION 2.03.  Redemption of Stock.  Whenever the Company shall
   elect to redeem shares of Stock in accordance with the provisions of
   the Certificate, it shall (unless otherwise agreed in writing with the
   Depositary) mail notice to the Depositary of such proposed redemption,
   by first class mail, postage prepaid, not less than 40 or more than 70
   days prior to the date fixed for redemption of Stock in accordance
   with Section 3(b) of the Certificate.  On the date of such redemption,
   provided that the Company shall then have paid in full to the
   Depositary the redemption price of the Stock to be redeemed, plus any
   accrued and unpaid dividends thereon, the Depositary shall redeem the
   Depositary Shares relating to such Stock.  The Depositary shall mail
   notice of such redemption and the proposed simultaneous redemption of
   the number of Depositary Shares relating to the Stock to be redeemed,
   by first-class mail, postage prepaid, not less than 30 and not more
   than 60 days prior to the date fixed for redemption of such Stock and
   Depositary Shares (the "Redemption Date"), to the Record Holders of
   the Depositary Shares to be so redeemed, at the addresses of such
   holders as they appear on the records of the Depositary; provided,
   however, neither failure to mail  any such notice to one or more such
   holders nor any defect in any notice to one or more such holders shall
   affect the sufficiency of the proceedings for redemption as to other

                                      4<PAGE>





   holders. Each such notice shall state: (i) the Redemption Date; (ii)
   the place or places where Receipts evidencing Depositary Shares are to
   be surrendered for payment of the redemption price; (iii) the
   redemption price; (iv) that dividends in respect of the Stock
   underlying the Depositary Shares to be redeemed will cease to accrue
   and accumulate at the close of business on such Redemption Date; (v)
   the number of Depositary Shares to be redeemed and, if less than all
   the Depositary Shares held by any such holder are to be redeemed, the
   number of such Depositary Shares held by such holder to be so
   redeemed; and (vi) if a date other than the Redemption Date, the date
   from and after which the Stock and Depositary Shares shall no longer
   be deemed to be outstanding. In case less than all the outstanding
   Depositary Shares are to be redeemed, the Depositary Shares to be so
   redeemed shall be selected by lot, pro rata or such other method as
   may be determined by the Depositary to be equitable.

        Notice having been mailed by the Depositary as aforesaid, from
   and after the Redemption Date (unless the Company shall have failed to
   redeem the shares of Stock to be redeemed by it as set forth in the
   Company's notice provided for in the preceding paragraph) all
   dividends in respect of the Depositary Shares so called for redemption
   shall cease to accrue and accumulate, the Depositary Shares being
   redeemed from such proceeds shall be deemed to be no longer
   outstanding, all rights of the holders of Receipts evidencing such
   Depositary Shares (except the right to receive the redemption price)
   shall, to the extent of such Depositary Shares, cease and terminate
   and, upon surrender in accordance with such notice of the Receipts
   evidencing any such Depositary Shares (properly endorsed or assigned
   for transfer, if the Depositary shall so require), such Depositary
   Shares shall be redeemed by the Depositary at a redemption price per
   Depositary Share equal to the proportionate part of the redemption
   price per share paid in respect of the shares of Stock plus all money
   and other property, if any, paid with respect to such Depositary
   Shares, including all amounts paid by the Company in respect of
   dividends which on the Redemption Date have accumulated on the shares
   of Stock to be so redeemed and have not theretofore been paid.

        If less than all the Depositary Shares evidenced by a Receipt are
   called for redemption, the Depositary will deliver to the holder of
   such Receipt upon its surrender to the Depositary, together with the
   redemption payment, a new Receipt evidencing the Depositary Shares
   evidenced by such prior Receipt and not called for redemption;
   provided, however, that such Replacement Receipt shall be issued only
   in denominations of whole Depositary Shares and cash will be payable
   in respect of fractional interests.

        SECTION 2.04.  Registration of Transfer of Receipts.  Subject to
   the terms and conditions of this Deposit Agreement, the Depositary
   shall register on its books from time to time transfers of Depositary
   Shares upon any surrender of the Receipt or Receipts evidencing such
   Depositary Shares by the holder in person or by duly authorized
   attorney, properly endorsed or accompanied by a properly executed

                                      5<PAGE>





   instrument of transfer; provided, however, that except as otherwise
   provided herein or in any Book-Entry Receipt, each Book-Entry Receipt
   may be transferred only in whole and only to the Depositary, to
   another nominee of the Depositary, to a successor depository, or to a
   nominee of a successor depository. Thereupon the Depositary shall
   execute a new Receipt or Receipts evidencing the same aggregate number
   of Depositary Shares as those evidenced by the Receipt or Receipts
   surrendered and deliver such new Receipt or Receipts to or upon the
   order of the person entitled thereto.

        SECTION 2.05.  Split-ups and Combinations of Receipts; Surrender
   of Depositary Shares and Withdrawal of Stock.  Upon surrender of a
   Receipt or Receipts at the Depositary's Office or at such other
   offices as it may designate for the purpose of effecting a split-up or
   combination of such Receipt or Receipts, and subject to the terms and
   conditions of this Deposit Agreement, the Depositary shall execute and
   deliver a new Receipt or Receipts in the denominations requested,
   evidencing the aggregate number of Depositary Shares evidenced by the
   Receipt or Receipts surrendered.  The Depositary shall give prompt
   notice of such action and the certificate numbers to the Registrar for
   the purposes of recording such split-up or consolidation.

        Unless the Depositary Shares have previously been called for
   redemption, any holder of Depositary Shares may withdraw the number of
   whole shares of Stock underlying such Depositary Shares and all money
   and other property, if any, underlying such Depositary Shares by
   surrendering Receipts evidencing such Depositary Shares at the
   Depositary's Office or at such other offices as the Depositary may
   designate for such withdrawals. Thereafter, without unreasonable
   delay, the Depositary shall deliver to such holder, or to the person
   or persons designated by such holder as hereinafter provided, the
   number of whole shares of Stock and all money and other property, if
   any, underlying the Depositary Shares so surrendered for withdrawal,
   but holders of such whole shares of Stock will not thereafter be
   entitled to deposit such Stock hereunder or to receive Receipts
   evidencing Depositary Shares therefor.  If a Receipt or Receipts
   delivered by a holder to the Depositary in connection with such
   withdrawal shall evidence in the aggregate a number of Depositary
   Shares in excess of the number of Depositary Shares representing the
   number of whole shares of Stock to be so withdrawn, the Depositary
   shall at the same time, in addition to such number of whole shares of
   Stock and such money and other property, if any, to be so withdrawn,
   deliver to such holder, or (subject to Sections 2.04 and 3.02) upon
   his order, a new Receipt evidencing such excess number of Depositary
   Shares.  Delivery of the Stock and money and other property being
   withdrawn may be made by delivery of such certificates, documents of
   title and other instruments as the Depositary may deem appropriate. 

        Stock delivered pursuant to the preceding paragraph may be
   endorsed with or have incorporated in the text thereof such legend or
   recitals or changes not inconsistent with the provisions of this
   Deposit Agreement as may be required by the Depositary or required to

                                      6<PAGE>





   comply with any applicable law or any regulation thereunder or with
   the rules and regulations of any securities exchange upon which the
   Stock may be listed or to conform with any usage with respect thereto,
   or to indicate any special limitations or restrictions to which any
   particular shares of Stock are subject.

        If the Stock and the money and other property being withdrawn are
   to be delivered to a person or persons other than the Record Holder of
   the Depositary Shares evidenced by the Receipts being surrendered for
   withdrawal of Stock, such holder shall execute and deliver to the
   Depositary a written order so directing the Depositary and the
   Depositary may require that the Receipt or Receipts surrendered by
   such holder for withdrawal of such shares of Stock be properly
   endorsed in blank or accompanied by a properly executed instrument of
   transfer in blank.

        Delivery of the Stock and money and other property, if any,
   underlying the Depositary Shares surrendered for withdrawal shall be
   made by the Depositary at the Depositary's Office, except that, at the
   request, risk and expense of the holder surrendering such Depositary
   Shares and for the account of such holder, such delivery may be made
   at such other place as may be designated by such holder.

        SECTION 2.06.  Limitations on Execution and Delivery, Transfer,
   Surrender and Exchange of Receipts.  As a condition precedent to the
   execution and delivery, registration of transfer, split-up,
   combination, surrender or exchange of any Receipt, the Depositary, any
   of the Depositary's Agents or the Company may require payment to it of
   a sum sufficient for the payment (or, in the event that the Depositary
   or the Company shall have made such payment, the reimbursement to it)
   of any charges or expenses payable by the holder of a Receipt pursuant
   to Section 5.07, may require the production of evidence satisfactory
   to it as to the identity and genuineness of any signature and may also
   require compliance with the rules and regulations of any governmental
   body, the New York Stock Exchange, any applicable self regulatory body
   or such regulations, if any, as the Depositary or the Company may
   establish consistent with the provisions of this Deposit Agreement.

        The delivery of Receipts against Stock may be suspended, the
   registration of transfer of Depositary Shares may be refused and the
   registration of transfer, surrender or exchange of outstanding
   Depositary Shares may be suspended (i) during any period when the
   register of stockholders of the Company is closed or (ii) if any such
   action is deemed necessary or advisable by the Depositary, any of the
   Depositary's Agents or the Company at any time or from time to time
   because of any requirement of law or of any government or governmental
   body or commission, New York Stock Exchange or under any provision of
   this Deposit Agreement.

        SECTION 2.07.  Lost Receipts, etc.  In case any Receipt shall be
   mutilated, destroyed, lost or stolen, the Depositary in its discretion
   may execute and deliver a Receipt of like form and tenor in exchange

                                      7<PAGE>





   and substitution for such mutilated Receipt or in lieu of and in
   substitution for such destroyed, lost or stolen Receipt, upon (i) the
   filing by the holder thereof with the Depositary of evidence
   satisfactory to the Depositary of such destruction or loss or theft of
   such Receipt, of the authenticity thereof and of his or her ownership
   thereof and (ii) the holder's furnishing of the Depositary with
   reasonable indemnification satisfactory to such Depositary and the
   Company. 

        SECTION 2.08.  Cancellation and Destruction of Surrendered
   Receipts.  All Receipts surrendered to the Depositary or any
   Depositary's Agent shall be canceled by the Depositary.  Except as
   prohibited by applicable law or regulation, the Depositary is
   authorized to destroy all Receipts so canceled. 

        SECTION 2.09. Book-Entry Receipts. (a) All or a portion of the
   Receipts may be represented by one or more Book-Entry Receipts
   deposited with [the Depository Trust Company] (the "Depository") and
   registered in the name of [Cede & Co.], a nominee of the Depository. 
   Each Book-Entry Receipt shall bear such legend or legends as may be
   required by the Depository in order for it to accept the Depositary
   Shares for its book-entry settlement system.  Except as provided for
   in Section 2.09(b) hereof, no person acquiring Receipts with book-
   entry settlement through the Depository shall receive or be entitled
   to receive definitive Receipts.  Ownership of beneficial interests in
   the Depositary Shares shall be shown on, and the transfer of such
   ownership shall be affected through, records maintained by (i) the
   Depository or its nominee for each Book-Entry Receipt, or (ii)
   institutions that have accounts with the Depository (such institution,
   with respect to a Depositary Share in its account, a "Participant").

        (b)  If the Depository subsequently ceases to make its book-entry
   system available for the Depositary Shares, the Company may instruct
   the Depository regarding making other arrangements for book-entry
   settlement.  In the event that the Depositary Shares are not eligible
   for, or it is no longer necessary to have the Depositary Shares
   available in, book-entry form, the Depositary shall provide written
   instructions to the Depository to deliver to the Depositary for
   cancellation each Book-Entry Receipt, and the Company shall instruct
   the Depository to deliver to the Depositary definitive Receipts in
   physical form evidencing such Depositary Shares.  Such definitive
   Receipts shall be in the form amended hereto as Exhibit A with
   appropriate insertions, modification and omissions, as provided above.

                                 ARTICLE III

                     CERTAIN OBLIGATIONS OF THE HOLDERS
                         OF RECEIPTS AND THE COMPANY

        SECTION 3.01.  Filing Proofs, Certificates and Other Information. 
   Any holder of a Depositary Share may be required from time to time to
   file such proof of residence, or other matters or other information,

                                      8<PAGE>





   to obtain such guarantees of signature, to execute such certificates
   and to make such representations and warranties as the Depositary or
   the Company may deem reasonably necessary or proper.  The Depositary
   or the Company may withhold the delivery, or delay the registration of
   transfer, redemption or exchange, of any Depositary Share or the
   withdrawal of any Stock underlying Depositary Shares or the
   distribution of any dividend or other distribution or the sale of any
   rights or of the proceeds thereof until such proof or other
   information is filed or such certificates are executed or such
   representations and warranties are made. 

        SECTION 3.02.  Payment of Taxes or Other Governmental Charges.
   Holders of Depositary Shares shall be obligated to make payments to
   the Depositary of certain charges and expenses as provided in Section
   5.07.  Registration of transfer of any Depositary Share or any
   withdrawal of Stock and delivery of all money or other property, if
   any, underlying such Depositary Share may be refused until any such
   payment due is made, and any dividends or other distributions may be
   withheld or all or any part of the Stock or other property relating to
   such Depositary Shares and not theretofore sold may be sold for the
   account of the holder thereof (after attempting by reasonable means to
   notify such holder prior to such sale), and such dividends or other
   distributions or the proceeds of any such sale may be applied to any
   payment of such charges or expenses, the holder of such Depositary
   Share remaining liable for any deficiency. 

        SECTION 3.03.  Warranty as to Stock.  The Company hereby
   represents and warrants to the Depositary that the Stock, when issued,
   will be validly issued, fully paid and nonassessable.  Such
   representation and warranty shall survive the deposit of the Stock and
   the issuance of the Receipts. 

        SECTION 3.04.  Warranty as to Receipts.  The Depositary hereby
   represents and warrants that the Receipts, when issued, will be legal,
   valid and binding obligations of the Depositary, enforceable against
   the Depositary in accordance with their terms, subject to bankruptcy,
   insolvency, fraudulent transfer, reorganization, moratorium and
   similar laws of general applicability relating to or affecting
   creditors' rights and to general equity principles. Such
   representation and warranty shall survive the deposit of the Stock and
   the issuance of the Receipts.

                                 ARTICLE IV

                      THE DEPOSITED SECURITIES; NOTICES

        SECTION 4.01.  Cash Distributions.  Whenever the Depositary shall
   receive any cash dividend or other cash distribution on the Stock, the
   Depositary shall, subject to Sections 3.01 and 3.02, distribute to the
   Record Holders of Depositary Shares on the record date fixed pursuant
   to Section 4.04 such amounts of such dividend or distribution as are,
   as nearly as practicable, in proportion to the respective numbers of

                                      9<PAGE>





   Depositary Shares held by such holders; provided, however, that in
   case the Company or the Depositary shall be required to withhold and
   shall withhold from any cash dividend or other cash distribution in
   respect of the Stock an amount on account of taxes, the amount made
   available for distribution or distributed in respect of Depositary
   Shares shall be reduced accordingly.  The Depositary shall distribute
   or make available for distribution, as the case may be, only such
   amount, however, as can be distributed without attributing to any
   holder of Depositary Shares a fraction of one cent, and any balance
   not so distributable shall be held by the Depositary (without
   liability for interest thereon) and shall be added to and be treated
   as part of the next succeeding distribution to record holders of
   Receipts. 

        SECTION 4.02.  Distributions Other than Cash.  Whenever the
   Depositary shall receive any distribution other than cash with respect
   to the Stock, the Depositary shall, subject to Sections 3.01 and 3.02,
   distribute to the Record Holders of Depositary Shares on the record
   date fixed pursuant to Section 4.04 such amounts of the securities or
   property received by it as are, as nearly as practicable, in
   proportion to the respective numbers of Depositary Shares held by such
   holders, in any manner that the Depositary may deem equitable and
   practicable for accomplishing such distribution.  If in the opinion of
   the Depositary such distribution cannot be made proportionately among
   such Record Holders, or if for any other reason (including any
   requirement that the Company or the Depositary withhold an amount on
   account of taxes or governmental charges) the Depositary deems, after
   consultation with the Company, such distribution not to be feasible,
   the Depositary may, with the approval of the Company, adopt such
   method as it deems equitable and practicable for the purpose of
   effecting such distribution, including the sale (at public or private)
   of the securities or property thus received, or any part thereof, at
   such place or places and upon such terms as it may deem proper.  The
   net proceeds of any such sale shall, subject to Sections 3.01 and
   3.02, be distributed or made available for distribution, as the case
   may be, by the Depositary to the Record Holders of Depositary Shares
   entitled thereto as provided by Section 4.01 in the case of a
   distribution received in cash. The Company shall not make any
   distribution of such securities unless the Company shall have provided
   an opinion of counsel to the effect that such securities have been
   registered under the Securities Act or do not need to be registered.

        SECTION 4.03.  Subscription Rights, Preferences or Privileges. 
   If the Company shall at any time offer or cause to be offered to the
   persons in whose names Stock is recorded on the books of the Company
   any rights, preferences or privileges to subscribe for or to purchase
   any securities or any rights, preferences or privileges of any other
   nature, such rights, preferences or privileges shall in each such
   instance be made available by the Depositary to the Record Holders of
   Depositary Shares in such manner as the Depositary may determine,
   either by the issue to such Record Holders of warrants representing
   such rights, preferences or privileges or by such other method as may

                                     10<PAGE>





   be approved by the Depositary in its discretion with the approval of
   the Company; provided, however, that (i) if at the time of issue or
   offer of any such rights, preferences or privileges the Depositary
   determines that it is not lawful or (after consultation with the
   Company) not feasible to make such rights, preferences or privileges
   available to holders of Depositary Shares by the issue of warrants or
   otherwise, or (ii) if and to the extent so instructed by holders of
   Depositary Shares who do not desire to exercise such rights,
   preferences or privileges, then the Depositary, in its discretion
   (with the approval of the Company, in any case where the Depositary
   has determined that it is not feasible to make such rights,
   preferences or privileges available), may, if applicable laws or the
   terms of such rights, preferences or privileges permit such transfer,
   sell such rights, preferences or privileges at public or private sale,
   at such place or places and upon such terms as it may deem proper. 
   The net proceeds of any such sale shall, subject to Sections 3.01 and
   3.02, be distributed by the Depositary to the Record Holders of
   Depositary Shares entitled thereto as provided by Section 4.01 in the
   case of a distribution received in cash.  The Company shall not make
   any distribution of such rights, preferences or privileges unless the
   Company shall have provided an opinion of counsel to the effect that
   such rights, preferences or privileges have been registered under the
   Securities Act or do not need to be registered. 

        If registration under the Securities Act of the securities to
   which any rights, preferences or privileges relate is required in
   order for holders of Depositary Shares to be offered or sold the
   securities to which such rights, preferences or privileges relate, the
   Company agrees with the Depositary that it will file promptly a
   registration statement pursuant to such Act with respect to such
   rights, preferences or privileges and securities and use its best
   efforts and take all steps available to it to cause such registration
   statement to become effective sufficiently in advance of the
   expiration of such rights, preferences or privileges to enable such
   holders to exercise such rights, preferences or privileges.  In no
   event shall the Depositary make available to the holders of Depositary
   Shares any right, preference or privilege to subscribe for or to
   purchase any securities unless and until such a registration statement
   shall have become effective, or unless the offering and sale of such
   securities to such holders are exempt from registration under the
   provision of such Act. 

        If any other action under the laws of any jurisdiction or any
   governmental or administrative authorization, consent or permit is
   required in order for such rights, preferences or privileges to be
   made available to the holders of Depositary Shares, the Company agrees
   with the Depositary that the Company will use its best efforts to take
   such action or obtain such authorization, consent or permit
   sufficiently in advance of the expiration of such rights, preferences
   or privileges to enable such holders to exercise such rights,
   preferences or privileges.

        SECTION 4.04.  Notice of Dividends, etc.; Fixing of Record Date
   for Holders of Depositary Shares.  (i) Whenever any cash dividend or
   other cash distribution shall become payable or any distribution other
   than cash shall be made, (ii) if rights, preferences or privileges
   shall at any time be offered, with respect to the Stock, (iii)
   whenever the Depositary shall receive notice of (a) any meeting at
   which holders of Stock are entitled to vote or of which holders of
   Stock are entitled to notice, or (b) any election by the Company to
   redeem any shares of Stock, or (iv) whenever the Depositary and the
   Company shall decide it is appropriate) the Depositary shall in each
   such instance fix a record date (which shall be the same date as the
   record date fixed by the Company with respect to the Stock) for the
   determination of the holders of Depositary Shares who shall be
   entitled to receive a distribution in respect of such dividend,
   distribution, rights, preferences or privileges or the net proceeds of
   the sale thereof, or to give instructions for the exercise of voting
   rights at any such meeting, or who shall be entitled to receive notice
   of such meeting.

        SECTION 4.05.  Voting Rights.  Upon receipt of notice of any
   meeting at which the holders of the Stock are entitled to vote, the
   Depositary shall, as soon as practicable thereafter, mail to the
   Record Holders of Depositary Shares a notice which shall contain (i)
   such information as is contained in such notice of meeting and (ii) a
   statement informing holders of Depositary Shares that they may
   instruct the Depositary as to the exercise of the voting rights
   pertaining to the amount of Stock underlying their respective
   Depositary Shares and a brief statement as to the manner in which such
   instructions may be given.  Upon the written request of the holders of
   Depositary Shares on the record date established in accordance with
   Section 4.04, the Depositary shall endeavor insofar as practicable to
   vote or cause to be voted, in accordance with the instructions set
   forth in such requests, the maximum number of whole shares of Stock
   underlying the Depositary Shares as to which any particular voting or
   consent instructions are received.  The Company hereby agrees to take
   all action which may be deemed necessary by the Depositary in order to
   enable the Depositary to vote such Stock or cause such Stock to be
   voted.  In the absence of specific instructions from the holder of a
   Depositary Share, the Depositary will abstain from voting (but, at its
   discretion, not from appearing at any meeting held with respect to
   such Stock unless directed to the contrary by the holders of all the
   Depositary Shares) to the extent of the Stock underlying the
   Depositary Shares evidenced by such Receipt.

        SECTION 4.06.  Changes Affecting Deposited Securities and
   Reclassifications, Recapitalizations, etc.  Upon any change in par or
   liquidation value, split-up, combination or other reclassification of
   the Stock, or upon any recapitalization, reorganization, merger,
   amalgamation or consolidation affecting the Company or to which it is
   a party, the Depositary may in its discretion, with the approval of,
   and shall upon the instructions of, the Company, and (in either case)
   in such manner as the Depositary may deem equitable, (i) make such

                                     12<PAGE>





   adjustments in (a) the fraction of an interest in one share of Stock
   underlying one Depositary Share and (b) the ratio of the redemption
   price per Depositary Share to the redemption price of a share of the
   Stock, in each case as may be necessary to reflect fully the effects
   of such change in par or liquidation value, split-up, combination or
   other reclassification of the Stock, or of such recapitalization,
   reorganization, merger, amalgamation or consolidation and (ii) treat
   any securities which shall be received by the Depositary in exchange
   for or upon conversion of or in respect of the Stock as new deposited
   securities so received in exchange for or upon conversion of or in
   respect of such Stock. In any such case the Depositary may in its
   discretion, with the approval of the Company, execute and deliver
   additional Receipts, or may call for the surrender of all outstanding
   Receipts to be exchanged for new Receipts specifically describing such
   new deposited securities.

        Anything to the contrary herein or in the Receipt
   notwithstanding, holders of Receipts shall have the right from and
   after the effective date or any such change in par or stated value,
   split-up, combination or other reclassification of the Stock or any
   such recapitalization, reorganization, merger, amalgamation,
   consolidation or sale, to the extent that holders of Stock had the
   right, prior to or on the applicable effective date, to convert,
   exchange or surrender shares of Stock into or for other stock,
   securities, property or cash, to surrender such Receipts to the
   Depositary with instructions to convert, exchange or surrender the
   Stock represented thereby only into or for, as the case may be, the
   kind and amount of shares of stock and other securities and property
   and cash into which the Stock represented by such Receipts has been
   converted or for which such Stock might have been exchanged or
   surrendered immediately prior to the effective date of such
   transaction. 

        SECTION 4.07.  Delivery of Reports.  The Depositary will forward
   to Record Holders of Receipts, at their respective addresses appearing
   in the Depositary's books, all notices, reports and communications
   received from the Company which are delivered to the Depositary and
   which the Company is required to furnish to the holders of Stock or
   Receipts.

        SECTION 4.08.  List of Holders.  Promptly upon request from time
   to time by the Company, the Depositary shall furnish to it a list, as
   of a recent date, of the names, addresses and holdings of Depositary
   Shares of all persons in whose names Depositary Shares are registered
   on the books of the Depositary or Registrar, as the case may be.

                  THE DEPOSITARY, THE DEPOSITARY'S AGENTS, 
                        THE REGISTRAR AND THE COMPANY

        SECTION 5.01.  Maintenance of Offices, Agencies and Transfer
   Books by the Depositary; Registrar.  Upon execution of this Deposit
   Agreement, the Depositary shall maintain at the Depositary's Offices
   or at any Registrar's Office, facilities for the execution and
   delivery, surrender and exchange of Receipts and the registration and
   registration of transfer of Depositary Shares and at the offices of
   the Depositary's Agents, if any, facilities for the delivery,
   surrender and exchange of Receipts and the registration of transfer of
   Depositary Shares, all in accordance with the provisions of this
   Deposit Agreement.  The Depositary shall have complete access to all
   books and records maintained on the Company's behalf at such
   Depositary's Offices or at such Registrar's Offices.

        The Depositary shall keep books at the Depositary's Office for
   the registration and registration of transfer of Depositary Shares,
   which books at all reasonable times shall be open for inspection by
   the Record Holders of Depositary Shares; provided, that any such
   holder requesting to exercise such right shall certify to the
   Depositary that such inspection shall be for a proper purpose
   reasonably related to such person's interest as an owner of Depositary
   Shares.

        The Depositary may close such books, at any time or from time to
   time, when deemed expedient by it in connection with the performance
   of its duties hereunder.

        If the Receipts or the Depositary Shares evidenced thereby or the
   Stock underlying such Depositary Shares shall be listed on the New
   York Stock Exchange, the Depositary may, with the approval of the
   Company, appoint a Registrar for registration of such Receipts or
   Depositary Shares in accordance with any requirements of such
   Exchange.  Such Registrar (which may be the Depositary if so permitted
   by the requirements of such Exchange) may be removed and a substitute
   registrar appointed by the Depositary upon the request or with the
   approval of the Company.  If such Receipts, such Depositary Shares or
   such Stock are listed on one or more other stock exchanges, the
   Depositary will, at the request of the Company, arrange such
   facilities for the delivery, registration, registration of transfer,
   surrender and exchange of such Receipts, such Depositary Shares or
   such Stock as may be required by law or applicable stock exchange
   regulation.

        SECTION 5.02.  Prevention of or Delay in Performance by the
   Depositary, the Depositary's Agents, any Registrar or the Company. 
   Neither the Depositary nor any of the Depositary's Agent nor any
   Registrar nor the Company shall incur any liability to any holder of
   any Depositary Share if by reason of any provision of any present or

                                     14<PAGE>





   future law, or regulation thereunder, of the United States of America
   or of any other governmental authority or, in the case of the
   Depositary, any Depositary's Agent or any Registrar, by reason of any
   provision, present or future, of the Company's Certificate of
   Incorporation (including the Certificate) or by reason of any act of
   God or war or other circumstance beyond the control of the relevant
   party, the Depositary, any Depositary's Agent, any Registrar or the
   Company shall be prevented or forbidden from doing or performing any
   act or thing which the terms of this Deposit Agreement provide shall
   be done or performed; nor shall the Depositary, any Depositary's
   Agent, any Registrar or the Company incur any liability to any holder
   of a Depositary Share (i) by reason of any nonperformance or delay,
   caused as aforesaid, in the performance of any act or thing which the
   terms of this Deposit Agreement provide shall or may be done or
   performed, or (ii) by reason of any exercise of, or failure to
   exercise, any discretion provided for in this Deposit Agreement
   except, in the case of any such exercise or failure to exercise
   discretion not caused as aforesaid, if caused by the gross negligence
   or willful misconduct of the party charged with such exercise or
   failure to exercise.

        SECTION 5.03.  Obligations of the Depositary, the Depositary's
   Agents, any Registrar and the Company.  Neither the Depositary nor any
   Depositary's Agent nor any Registrar nor the Company assumes any
   obligation or shall be subject to any liability under this Deposit
   Agreement to holders of Depositary Shares other than for its
   negligence or willful misconduct.

        Neither the Depositary nor any Depositary's Agent nor any
   Registrar nor the Company shall be under any obligation to appear in,
   prosecute or defend any action, suit or other proceeding in respect of
   the Stock, the Depositary Shares or the Receipts which in its opinion
   may involve it in expense or liability unless indemnity satisfactory
   to it against all expense and liability be furnished as often as may
   be required.

        Neither the Depositary nor any Depositary's Agent nor any
   Registrar nor the Company shall be liable for any action or any
   failure to act by it in reliance upon the written advice of legal
   counsel or accountants, or information from any person presenting
   Stock for deposit, any holder of a Depositary Share or any other
   person believed by it in good faith to be competent to give such
   information.  The Depositary, any Depositary's Agent, any Registrar
   and the Company may each rely and shall each be protected in acting
   upon any written notice, request, direction or other document believed
   by it to be genuine and to have been signed or presented by the proper
   party or parties. 

        The Depositary shall not be responsible for any failure to carry
   out any instruction to vote any of the shares of Stock or for the
   manner or effect of any such vote, as long as any such action or non-
   action is in good faith. The Depositary undertakes and shall cause any

                                     15<PAGE>





   Registrar to undertake, to perform such duties and only such duties as
   are specifically set forth in this Deposit Agreement using its
   reasonable best efforts and in good faith.  The parties hereto
   acknowledge that no implied covenants or obligations shall be read
   into this Deposit Agreement against the Depositary or any Registrar.
   The Depositary will indemnify the Company against any liability which
   may arise out of acts performed or omitted by the Depositary or its
   agents due to its or their gross negligence or bad faith. The
   Depositary, any Depositary's Agents, any Registrar and the Company may
   own and deal in any class of securities of the Company and its
   affiliates and in Depositary Shares. The Depositary may also act as
   transfer agent or registrar of any of the securities of the Company
   and its affiliates.

        SECTION 5.04.  Resignation and Removal of the Depositary;
   Appointment of Successor Depositary.  The Depositary may at any time
   resign as Depositary hereunder by notice of its election so to do
   delivered to the Company, such resignation to take effect upon the
   appointment of a successor Depositary and its acceptance of such
   appointment as hereinafter provided.

        The Depositary may at any time be removed by the Company by
   notice of such removal delivered to the Depositary, such removal to
   take effect upon the appointment of a successor Depositary and its
   acceptance of such appointment as hereinafter provided.

        In case the Depositary acting hereunder shall at any time resign
   or be removed, the Company shall, within 60 days after the delivery of
   the notice of resignation or removal, as the case may be, appoint a
   successor Depositary, which shall be a bank or trust company having
   its principal office in the United States of America and having a
   combined capital and surplus of at least $50,000,000.  If no successor
   Depositary shall have been so appointed within 60 days after delivery
   of such notice, the resigning or removed Depositary may petition any
   court of competent jurisdiction for the appointment of a successor
   Depositary.  Every successor Depositary shall execute and deliver to
   its predecessor and to the Company an instrument in writing accepting
   its appointment hereunder, and thereupon such successor Depositary,
   without any further act or deed, shall become fully vested with all
   the rights, powers, duties and obligations of its predecessor and for
   all purposes shall be the Depositary under this Deposit Agreement, and
   such predecessor, upon payment of all sums due it and on the written
   request of the Company, shall execute and deliver an instrument
   transferring to such successor all rights and powers of such
   predecessor hereunder, shall duly assign, transfer and deliver all
   right, title and interest in the Stock and any moneys or property held
   hereunder to such successor and shall deliver to such successor a list
   of the Record Holders of all outstanding Depositary Shares.  Any
   successor Depositary shall promptly mail notice of its appointment to
   the Record Holders of Depositary Shares. 



                                     16<PAGE>





        Any corporation into or with which the Depositary may be merged,
   consolidated or converted shall be the successor of such Depositary
   without the execution or filing of any document or any further act. 
   Such successor Depositary may authenticate the Receipts in the name of
   the predecessor Depositary or in the name of the successor Depositary.

        SECTION 5.05.  Corporate Notices and Reports.  The Company agrees
   that it will deliver to the Depositary and the Depositary will,
   promptly after receipt thereof, transmit to the Record Holder of
   Depositary Shares, in each case at the address furnished to it
   pursuant to Section 4.08, all notices, reports and communications
   (including without limitation financial statements) required by law,
   the rules of any national securities exchange upon which the Stock,
   the Depositary Shares or the Receipts are listed or by the Company's
   Certificate of Incorporation (including the Certificate) to be
   furnished by the Company to holders of the Stock.  Such transmission
   will be at the Company's expense and the Company will provide the
   Depositary with such number of copies of such documents as the
   Depositary may reasonably request.

        SECTION 5.06.  Indemnification by the Company.  The Company shall
   indemnify the Depositary, any Depositary's Agent and any Registrar
   against, and hold each of them harmless from, any loss, liability or
   expense (including the costs and expenses of defending itself) which
   may arise out of (i) acts performed or omitted in connection with this
   Deposit Agreement and the Depositary Shares (a) by the Depositary, any
   Registrar or any of their respective agents (including any
   Depositary's Agent), except for any liability arising out of
   negligence, willful misconduct or bad faith on the respective parts of
   any such person or persons, or (b) by the Company or any of its
   agents, or (ii) the offer, sale or registration of the Depositary
   Shares or the Stock pursuant to the provisions hereof.  The
   obligations of the Company set forth in this Section 5.06 shall
   survive any succession of any Depositary, Registrar or Depositary's
   Agent.

        SECTION 5.07.  Charges and Expenses.  The Company shall pay all
   transfer and other taxes and governmental charges arising solely from
   the existence of the depositary arrangements.  The Company shall pay
   all charges of the Depositary in connection with the initial deposit
   of the Stock and the initial issuance of the Receipts, any redemption
   of the Stock at the option of the Company and any withdrawals of Stock
   by holders of Depositary Shares.  All other transfer and other taxes
   and governmental charges shall be at the expense of holders of
   Depositary Shares.  The Depositary may refuse to effect any transfer
   of a Receipt or any withdrawal of Stock evidenced hereby until all
   such taxes and charges with respect to such receipt or stock are paid
   by the holders thereof.  If, at the request of a holder of a
   Depositary Share, the Depositary incurs charges or expenses for which
   it is not otherwise liable hereunder, such holder will be liable for
   such charges and expenses.  All other charges and expenses of the
   Depositary, any Depositary's Agent hereunder and any Registrar

                                     17<PAGE>





   (including, in each case, fees and expenses of counsel) incident to
   the performance of their respective obligations hereunder will be paid
   upon consultation and agreement between the Depositary and the Company
   as to the amount and nature of such charges and expenses.  The
   Depositary shall present its statement for charges and expenses to the
   Company once every three months or at such other intervals as the
   Company and the Depositary may agree. 

                                 ARTICLE VI

                          AMENDMENT AND TERMINATION

        SECTION 6.01.  Amendment.  The form of the Receipts and any
   provisions of this Deposit Agreement may at any time and from time to
   time be amended by agreement between the Company and the Depositary in
   any respect which they may deem necessary or desirable; provided,
   however, that no such amendment which shall materially and adversely
   alter the rights of the existing holders of Depositary Shares shall be
   effective unless such amendment shall have been approved by the
   holders of at least a majority of the Depositary Shares then
   outstanding.  Every holder of an outstanding Depositary Share at the
   time any such amendment becomes effective shall be deemed, by
   continuing to hold such Depositary Share, to consent and agree to such
   amendment and to be bound by this Deposit Agreement as amended
   thereby.  In no event shall any amendment impair the right, subject to
   the provisions of Sections 2.05 and 2.06 hereof, of any owner of any
   Depositary Shares to surrender any Receipt evidencing such Depositary
   Shares to the Depositary with instructions to deliver to the holder
   the Stock and all money and other property, if any, represented
   thereby, except in order to comply with mandatory provisions of
   applicable law or the rules and regulations of any governmental body,
   agency or commission, the depository for any Book-Entry Receipts, the
   New York Stock Exchange or any applicable stock exchange.

        SECTION 6.02.  Termination.  This Deposit Agreement may be
   terminated by the Company or the Depositary only after (i) all
   outstanding Depositary Shares shall have been redeemed and any
   accumulated and unpaid dividends on the Stock represented by the
   Depositary Shares, together with all other moneys and property, if
   any, to which holders of the related Receipts are entitled under the
   terms of such Receipts or this Deposit Agreement, have been paid or
   distributed as provided in this Deposit Agreement or provision
   therefor has been duly made pursuant to Section 2.03, (ii) all the
   Stock has been withdrawn pursuant to Section 2.05 or (iii) there shall
   have been made a final distribution in respect of the Stock in
   connection with any liquidation, dissolution or winding up of the
   Company and such distribution shall have been distributed to the
   holders of Receipts pursuant to Section 4.01 or 4.02, as applicable. 
   Whenever the Deposit Agreement has been terminated pursuant to (iii)
   above, the Depositary will mail notice of such termination to the
   record holders of all Depositary Shares then outstanding at least 30
   days prior to the date fixed in that notice for termination of the

                                     18<PAGE>





   Deposit Agreement.  If any Depositary Shares remain outstanding after
   the date of termination, the Depositary thereafter will discontinue
   the transfer of Depositary Shares, will suspend the distribution of
   dividends to the owners thereof, and will not give any further notices
   (other than notice of such termination) or perform any further acts
   under this Deposit Agreement, except that the Depositary will continue
   (i) to collect dividends on the Stock and any other distributions with
   respect thereto and (ii) to deliver or cause to be delivered shares of
   Stock, together with such dividends and distributions, or principal
   and interest, and the net proceeds of any sales of rights,
   preferences, privileges or other property (other than real property)
   in exchange for Depositary Shares surrendered. At any time after the
   expiration of three years from the date of termination, the Depositary
   may sell the Stock then held by it at a public or private sale, at
   such place or places and upon such terms as it deems proper and may
   thereafter hold the net proceeds of such sale, without liability for
   interest, for the pro rata benefit of the owners of the Depositary
   Shares which have not theretofore been surrendered. Subject to
   applicable escheat laws, any monies set aside by the Company in
   respect of any payment with respect to the Stock represented by the
   Depositary Shares, or dividends thereon, and unclaimed at the end of
   three years from the date upon which such payment is due and payable
   shall revert to the general funds of the Company, after which
   reversion the holders of such Depositary Shares shall look only to the
   general funds of the Company for payment thereof. 

        Upon the termination of this Deposit Agreement, the parties
   hereto shall be discharged from all obligations under this Deposit
   Agreement except for their respective obligations under Sections 5.03,
   5.06 and 5.07.

   executed in any number of counterparts and by each of the parties
   hereto on separate counterparts, each of which counterparts, when so
   executed and delivered, shall be deemed an original, but all such
   counterparts taken together shall constitute one and the same
   instrument.

        SECTION 7.02.  Exclusive Benefit of Parties.  This Deposit
   Agreement is for the exclusive benefit of the parties hereto and their
   respective successors hereunder and shall not be deemed to give any

                                     19<PAGE>

   prejudiced or disturbed thereby. 

        SECTION 7.04.  Notices.  Any and all notices to be given to the
   Company hereunder or under the Receipts shall be in writing and shall

   request that notices intended for such holder be mailed to some other

   upon any telegram or telex message received by it from the other or

   telegram or telex message shall not subsequently be confirmed by
   letter or as aforesaid.

                 ISSUANCE OF WARRANTS AND FORM, EXECUTION, 
             DELIVERY AND REGISTRATION OF WARRANT CERTIFICATES 

        SECTION 1.01.  Issuance of Warrants.  Each Warrant shall

   therein, to purchase [________] Warrant Securities [in the aggregate
   principal amount of $_____] at the Exercise Price set forth in Section

   to be offered in Book-Entry form: [All] [A portion] of the Warrants
   shall initially be represented by one or more Book-Entry certificates
   (each, a "Book-Entry Warrant Certificate").]  [If Securities and

   Warrants for each [$_____ principal amount of] [_______] Securities
   included in such unit.]  [If Warrants are to be offered separately and
   in definitive form:  Each Warrant Certificate shall evidence [_______]

        SECTION 1.02.  Form, Execution and Delivery of Warrant
   Certificates. 

        (a)  One or more Warrant Certificates evidencing Warrants to
   purchase not more than [____] [$_______ in aggregate principal amount

   2.03(e)) may be executed by the Company and delivered to the Warrant


                                      2<PAGE>





   Agent upon the execution of this Warrant Agreement or from time to
   time thereafter.

        (b)  Each Warrant Certificate, whenever issued, shall be in
   registered form substantially in the form set forth in Exhibit A
   hereto, with such appropriate insertions, omissions, substitutions and
   other variations as are required or permitted by this Agreement.  [If
   Warrants are issued in Book-Entry form:  Each Book-Entry Warrant
   Certificate shall bear such legend or legends as may be required by
   the Depository in order for it to accept the Warrants for its book-
   entry settlement system.]  Each Warrant Certificate shall be printed,
   lithographed, typewritten, mimeographed or engraved or otherwise
   reproduced in any other manner as may be approved by the officers
   executing the same (such execution to be conclusive evidence of such
   approval) and may have such letters, numbers or other marks of
   identification or designation and such legends or endorsements
   printed, lithographed or engraved thereon as the officers of the
   Company executing the same may approve (such execution to be
   conclusive evidence of such approval) and as are not inconsistent with
   the provisions of this Agreement, or as may be required to comply with
   any law or with any rule or regulation made pursuant thereto, or with
   any regulation of any stock exchange on which the Warrants [If
   Securities and Warrants are to be offered together: the Securities] or
   the Warrant Securities may be listed, or to conform to usage.  Each
   Warrant Certificate shall be signed on behalf of the Company by its
   Chairman of the Board, Chief Executive Officer, President, Chief
   Financial Officer or any Vice President.  The signature of any such
   officer on any Warrant Certificate may be manual or facsimile.  Each
   Warrant Certificate, when so signed on behalf of the Company, shall be
   delivered to the Warrant Agent together with an order for the
   countersignature and delivery of such Warrants.

        (c)  The Warrant Agent shall, upon receipt of any Warrant
   Certificate duly executed on behalf of the Company, countersign such
   Warrant Certificate and deliver such Warrant Certificate to or upon
   the order of the Company.  Each Warrant Certificate shall be dated the
   date of its countersignature.

        (d)  No Warrant Certificate shall be entitled to any benefit
   under this Agreement or be valid or obligatory for any purpose, and no
   Warrant evidenced thereby may be exercised, unless such Warrant
   Certificate has been countersigned by the manual signature of the
   Warrant Agent.  Such signature by the Warrant Agent upon any Warrant
   Certificate executed by the Company shall be conclusive evidence that
   such Warrant Certificate has been duly issued under the terms of this
   Agreement.

        (e)  If any officer of the Company who has signed any Warrant
   Certificate either manually or by facsimile signature shall cease to
   be such officer before such Warrant Certificate shall have been
   countersigned and delivered by the Warrant Agent, such Warrant
   Certificate nevertheless may be countersigned and delivered as though

                                      3<PAGE>





   the person who signed such Warrant Certificate had not ceased to be
   such officer of the Company; and any Warrant Certificate may be signed
   on behalf of the Company by such persons as, at the actual date of the
   execution of such Warrant Certificate, shall be the proper officers of
   the Company as specified in this Section 1.02, regardless of whether
   at the date of the execution of this Agreement any such person was
   such officer.

        (f)  The Holders shall [If Warrants are to be issued in Book-
   Entry form: , except as stated below with respect to Warrants
   evidenced by a Book-Entry Warrant Certificate,] be entitled to receive
   Warrants in physical, certificated form.   [If Warrants are to be
   issued in Book-Entry form: 

        (g)  A Book-Entry Warrant Certificate may be exchanged for a new
   Book-Entry Warrant Certificate, or one or more new Book-Entry Warrant
   Certificates may be issued, to reflect the issuance by the Company of
   additional Warrants.  To effect such an exchange, the Company shall
   deliver to the Warrant Agent one or more new Book-Entry Warrant
   Certificates duly executed on behalf of the Company as provided in
   Section 1.02. The Warrant Agent shall authenticate each new Book-Entry
   Warrant Certificate as provided in Section 1.02 and shall deliver each
   new Book-Entry Warrant Certificate to the Depository.  The Warrant
   Agent shall cancel each Book-Entry Warrant Certificate delivered to it
   by the Depository in exchange therefor, if any.]

        SECTION 1.03.  Transfer of Warrants.   [If Warrants are to be
   issued in Book-Entry form:

        (a)  [All] [A portion] of the Warrants shall initially be
   represented by one or more Book-Entry Warrant Certificates deposited
   with [the Depository Trust Company] (the "Depository") and registered
   in the name of [Cede & Co.], a nominee of the Depository.  Except as
   provided for in Section 1.03(b) hereof, no person acquiring Warrants
   with book-entry settlement through the Depository shall receive or be
   entitled to receive physical delivery of definitive Warrant
   Certificates evidencing such Warrants.  Ownership of beneficial
   interests in the Warrants shall be shown on, and the transfer of such
   ownership shall be effected through, records maintained by (i) the
   Depository or its nominee for each Book-Entry Warrant Certificate, or
   (ii) institutions that have accounts with the Depository (such
   institution, with respect to a Warrant in its account, a
   "Participant").] [If Warrants are to be issued in Book-Entry form:  

        (b)  If the Depository subsequently ceases to make its book-entry
   settlement system available for the Warrants, the Company may instruct
   the Warrant Agent regarding making other arrangements for book-entry
   settlement.  In the event that the Warrants are not eligible for, or
   it is no longer necessary to have the Warrants available in, book-
   entry form, the Warrant Agent shall provide written instructions to
   the Depository to deliver to the Warrant Agent for cancellation each

   Warrant Agent to deliver to the Depository definitive Warrant
   Certificates in physical form evidencing such Warrants.  Such
   definitive Warrant Certificates shall be in the form annexed hereto as
   Exhibit A with appropriate insertions, modifications and omissions, as
   provided above.] [If Securities and Warrants are to be offered
   together: 

        (c)  [If Warrants are not immediately detachable:  Prior to the
   Detachment Date,] Warrants may be -transferred or exchanged only
   together with the Security to which such Warrant is attached, and only
   for the purpose of effecting, or in conjunction with, a transfer or
   exchange of such Security.  Furthermore, [If Warrants are not
   immediately detachable: on or prior to the Detachment Date,] each
   transfer of a Security on the register relating to such Securities
   shall operate also to transfer the Warrants to which such Security was
   initially attached.  [If Warrants are not immediately detachable: From
   and after the Detachment Date, the above provisions shall be of no
   further force and effect.]

        (d)  A Warrant Certificate may be transferred at the option of
   the Holder thereof upon surrender of such Warrant Certificate at the
   corporate trust office of the Warrant Agent, properly endorsed or
   accompanied by appropriate instruments of transfer and written
   instructions for transfer, all in form satisfactory to the Company and
   the Warrant Agent [If Warrants are to be issued in Book-Entry form:
   provided, however, that except as otherwise provided herein or in any
   Book-Entry Warrant Certificate, each Book-Entry Warrant Certificate
   may be transferred only in whole and only to the Depository, to
   another nominee of the Depository, to a successor depository, or to a
   nominee of a successor depository].  Upon any such registration of
   transfer, the Company shall execute, and the Warrant Agent shall
   countersign and deliver, as provided in Section 1.02, in the name of
   the designated transferee a new Warrant Certificate or Warrant
   Certificates of any authorized denomination evidencing in the
   aggregate a like number of unexercised Warrants.

        (e)  [If Warrants are not immediately detachable: After the
   Detachment Date,] Upon surrender at the corporate office of the
   Warrant Agent, properly endorsed or accompanied by appropriate
   instruments of transfer and written instructions for such exchange,
   all in form satisfactory to the Company and the Warrant Agent, one or
   more Warrant Certificates may be exchanged for one or more Warrant
   Certificates in any other authorized denominations; provided that such
   new Warrant Certificate(s) evidence the same aggregate number of
   Warrants as the Warrant Certificate(s) so surrendered.  Upon any such
   surrender for exchange, the Company shall execute, and the Warrant
   Agent shall countersign and deliver, as provided in Section 1.02, in
   the name of the Holder of such Warrant Certificates, the new Warrant
   Certificates.

        (f)  The Warrant Agent shall keep, at its corporate trust office,
   books in which, subject to such reasonable regulations as it may

                                      5<PAGE>





   prescribe, it shall register Warrant Certificates in accordance with
   Section 1.02 and transfers, exchanges, exercises and cancellations of
   outstanding Warrant Certificates. Whenever any Warrant Certificates
   are surrendered for transfer or exchange in accordance with this
   Section 1.03, an authorized officer of the Warrant Agent shall
   manually countersign and deliver the Warrant Certificates which the
   Holder making the transfer or exchange is entitled to receive.

        (g)  No service charge shall be made for any transfer or exchange
   of Warrant Certificates, but the Company may require payment of a sum
   sufficient to cover any stamp or other tax or other governmental
   charge that may be imposed in connection with any such transfer or
   exchange.

        SECTION 1.04.  Lost, Stolen, Mutilated or Destroyed Warrant
   Certificates. Upon receipt by the Company and the Warrant Agent of
   evidence satisfactory to them of the ownership of and the loss, theft,
   destruction or mutilation of any Warrant Certificate and of indemnity
   satisfactory to them and, in the case of mutilation, upon surrender of
   such Warrant Certificate to the Warrant Agent for cancellation, then,
   in the absence of notice to the Company or the Warrant Agent that such
   Warrant Certificate has been acquired by a bona fide purchaser, the
   Company shall execute, and an authorized officer of the Warrant Agent
   shall manually countersign and deliver, in exchange for or in lieu of
   the lost, stolen, destroyed or mutilated Warrant Certificate, a new
   Warrant Certificate of the same tenor and for a like number of
   Warrants.  No service charge shall be made for any replacement of
   Warrant Certificates, but the Company may require the payment of a sum
   sufficient to cover any stamp or other tax or other governmental
   charge that may be imposed in connection with any such exchange. To
   the extent permitted under applicable law, the provisions of this
   Section 1.04 are exclusive with respect to the replacement of
   mutilated, lost, stolen or destroyed Warrant Certificates and shall
   preclude any and all other rights or remedies.

        SECTION 1.05.  Cancellation of Warrant Certificates.  Any Warrant
   Certificate surrendered to the Warrant Agent for transfer, exchange or
   exercise of the Warrants evidenced thereby shall be promptly canceled
   by the Warrant Agent and shall not be reissued and, except as
   expressly permitted by this Agreement, no Warrant Certificate shall be
   issued hereunder in lieu thereof. The Warrant Agent shall deliver to
   the Company from time to time or otherwise dispose of canceled Warrant
   Certificates in a manner satisfactory to the Company.  Any Warrant
   Certificate surrendered to the Company for transfer, exchange or
   exercise of the Warrants evidenced thereby shall be promptly delivered
   to the Warrant Agent and such transfer, exchange or exercise shall not
   be effective until such Warrant Certificate has been received by the
   Warrant Agent.

   attempted exercise of Warrants.  The validity of any exercise of
   Warrants will be determined by the Warrant Agent in its sole
   discretion and such determination will be final and binding upon the
   Holder and the Company. Neither the Company nor the Warrant Agent

   be,] together with, or preceded by the prospectus referred to in

   information and documents to the Warrant Agent as may be necessary for
   the Warrant Agent to fulfill its obligations hereunder.

   Warrant Agent as provided in Section 1.02 hereof, and delivered to the
   Holder at the address specified on the books of the Warrant Agent or
   as otherwise specified by such Holder.]

        (f)  The Company shall not be required to pay any stamp or other
   tax or other governmental charge required to be paid in connection
   with any transfer involved in the issue of the Warrant Securities; and
   in the event that any such transfer is involved, the Company shall not
   be required to issue or deliver any Warrant Securities until such tax
   or other charge shall have been paid or it has been established to the
   Company's satisfaction that no such tax or other charge is due.

   of  Warrant Agent] as Warrant Agent of the Company in respect of the
   Warrants upon the terms and subject to the conditions herein set
   forth, and [Name of Warrant Agent] hereby accepts such appointment. 
   The Warrant Agent shall have the powers and authority granted to and

   on behalf of the Company as the Company may hereafter grant to or
   confer upon it.

        SECTION 4.02.  Limitations on Warrant Agent's Obligations.  The
   Warrant Agent accepts its obligations herein set forth upon the terms
   and conditions hereof, including the following, to all of which the
   Company agrees and to all of which the rights hereunder of the Holders
   from time to time shall be subject:

        (a)  Compensation and Indemnification.  The Company agrees to pay
   the Warrant Agent compensation to be agreed upon with the Company for
   all services rendered by the Warrant Agent and to reimburse the
   Warrant Agent for all reasonable out-of-pocket expenses (including
   reasonable counsel fees) incurred by the Warrant Agent in connection
   with the services rendered by it hereunder.  The Company also agrees
   to indemnify the Warrant Agent for, and to hold it harmless against,
   any loss, liability or expense incurred without negligence, bad faith
   or breach of this Agreement on the part of the Warrant Agent, arising
   out of or in connection with its acting as Warrant Agent hereunder.

        (b)  Agent for the Company.  In acting in the capacity of Warrant
   Agent under this Agreement, the Warrant Agent is acting solely as
   agent of the Company and does not assume any obligation or
   relationship of agency or trust with any of the owners or holders of
   the Warrants except as expressly set forth herein.

        (c)  Counsel. The Warrant Agent may consult with counsel
   satisfactory to it (which may be counsel to the Company), and the
   advice of such counsel shall be full and complete authorization and
   protection in respect of any action taken, suffered or omitted by it
   hereunder in good faith and in accordance with the advice of such
   counsel.

                                     11<PAGE>





        (d)  Documents.  The Warrant Agent shall be protected and shall
   incur  no liability for or in respect of any action taken or thing
   suffered by it in reliance upon any notice, direction, consent,
   certificate, affidavit, statement or other paper or document
   reasonably believed by it to be genuine and to have been presented or
   signed by the proper parties.

        (e)  Certain Transactions.  The Warrant Agent, and its officers, 
   directors and employees, may become the owner of, or acquire any
   interest in, any Warrant, with the same rights that it or they would
   have were it not the Warrant Agent hereunder, and, to the extent
   permitted by applicable  law, it or they may engage or be interested
   in any financial or other transaction with the Company and may act on,
   or as a depositary, trustee or agent for, any committee or body of
   holders of Warrants [If Securities and Warrants are to be offered
   together: Securities] or Warrant Securities, or other securities or
   obligations of the Company as freely as if it were not the Warrant
   Agent hereunder.  Nothing in this Agreement shall be deemed to prevent
   the Warrant Agent from acting as trustee under either Indenture. 

        (f)  No Liability for Interest.  The Warrant Agent shall not be
   under any liability for interest on any monies at any time received by
   it pursuant to any of the provisions of this Agreement.

        (g)  No Liability for Invalidity.  The Warrant Agent shall not be

   of this Agreement or the execution and delivery hereof (except the due
   execution and delivery hereof by the Warrant Agent) or with respect to
   the validity or execution of the Warrant Certificates (except its
   countersignature thereon).

        (h)  No Responsibility for Recitals.  The recitals contained
   herein and in the Warrant Certificates (except as to the Warrant
   Agent's countersignature thereon) shall be taken as the statements of
   the Company and the Warrant Agent assumes no responsibility hereby for
   the correctness of the same.

        (i)  No Implied Obligations.  The Warrant Agent shall be
   obligated to perform such duties as are specifically set forth herein
   and no implied duties or obligations shall be read into this Agreement
   against the Warrant Agent. The Warrant Agent shall not be under any
   obligation to take any action hereunder which may tend to involve it
   in any expense or liability, the payment of which within a reasonable
   time is not, in its opinion, assured to it. The Warrant Agent  shall
   not be accountable or under any duty or responsibility for the use by
   the Company of any Warrant Certificate authenticated by the Warrant
   Agent and delivered by it to the Company pursuant to this Agreement or
   for the application by the Company of the proceeds of the issue and
   sale, or exercise, of the Warrants. The Warrant Agent shall have no
   duty or responsibility in case of any default by the Company in the
   performance of its covenants or agreements contained herein or in any
   Warrant Certificate or in the case of the receipt of any written

                                     12<PAGE>





   demand from a Holder with respect to such default, including, without
   limiting the generality of the foregoing, any duty or responsibility
   to initiate or attempt to initiate any proceedings at law or otherwise
   or, except as provided in Section 5.03 hereof, to make any demand upon
   the Company.

        SECTION 4.03.  Compliance With Applicable Laws. The Warrant Agent
   agrees to comply with all applicable federal and state laws imposing
   obligations on it in respect of the services rendered by it under this
   Agreement and in connection with the Warrants, including (but not
   limited to) the provisions of United States federal income tax laws
   regarding information reporting and backup withholding.  The Warrant
   Agent expressly assumes all liability for its failure to comply with
   any such laws imposing obligations on it, including (but not limited
   to) any liability for its failure to comply with any applicable
   provisions of United States federal income tax laws regarding
   information reporting and backup withholding.

        SECTION 4.04.  Resignation and Appointment of Successor. 

        (a)  The Company agrees, for the benefit of the Holders from time
   to time, that there shall at all times be a Warrant Agent hereunder
   until all the Warrants issued hereunder have been exercised or have
   expired in accordance with their terms, which Warrant Agent shall be a

   America or one of the states thereof, which is authorized under the
   laws of the jurisdiction of its organization to exercise corporate
   trust powers, has a combined capital and surplus of at least
   $50,000,000 and has an office or an agent's office in the United
   States of America.

        (b)  The Warrant Agent may at any time resign as such agent by
   giving written notice to the Company of such intention on its part,
   specifying the date on which it desires such resignation to become
   effective; provided that such date shall not be less than three months
   after the date on which such notice is given, unless the Company
   agrees to accept such notice less than three months prior to such date
   of effectiveness.  The Company may remove the Warrant Agent at any
   time by giving written notice to the Warrant Agent of such removal,
   specifying the date on which it desires such removal to become
   effective.  Such resignation or removal shall take effect upon the
   appointment by the Company, as hereinafter provided, of a successor
   Warrant Agent (which shall be a bank or trust company qualified as set
   forth in Section 4.04(a)) and the acceptance of such appointment by
   such successor Warrant Agent. The obligation of the Company under
   Section 4.02(a) shall continue to the extent set forth therein
   notwithstanding the resignation or removal of the Warrant Agent.

        (c)  If at any time the Warrant Agent shall resign, or shall
   cease to be qualified as set forth in Section 4.04(a), or shall be

        SECTION 5.01.  Amendments.
    
        (a)  This Agreement and any Warrant Certificate may be amended by
   the parties hereto by executing a supplemental warrant agreement (a
   "Supplemental Agreement"), without the consent of the Holder of any
   Warrant, for the purpose of (i) curing any ambiguity, or curing,
   correcting or supplementing any defective provision contained herein,
   or making any other provisions with respect to matters or questions
   arising under this Agreement that is not inconsistent with the
   provisions of this Agreement or the Warrant Certificates, (ii)
   evidencing the succession of another corporation to the Company and
   the assumption by any such successor of the covenants of the Company
   contained in this Warrant Agreement and the Warrants, (iii) evidencing
   and providing for the acceptance of appointment by a successor Warrant
   Agent with respect to the Warrants, [If Warrants are to be issued in
   Book-Entry form: (iv) evidencing and providing for the acceptance of
   appointment by a successor Depository with respect to each Book-Entry
   Warrant Certificate, (v) issuing definitive Warrant Certificates in
   accordance with paragraph (b) of Section 1.03,] (vi) adding to the
   covenants of the Company for the benefit of the Holders or
   surrendering any right or power conferred upon the Company under this
   Agreement, (vii) appointing a successor Warrant Agent, or (viii)
   amending this Agreement and the Warrants in any manner that the
   Company may deem to be necessary or desirable and that will not
   adversely affect the interests of the Holders in any material respect.

        (b)  The Company and the Warrant Agent may amend this Agreement
   and the Warrants by executing a Supplemental Agreement with the
   consent of the Holders of not fewer than a majority of the unexercised
   Warrants affected by such amendment, for the purpose of adding any
   provisions to or changing in any manner or eliminating any of the
   provisions of this Agreement or of modifying in any manner the rights
   of the Holders under this Agreement; provided, however, that, without
   the consent of each Holder of Warrants affected thereby, no such
   amendment may be made that (i) changes the Warrants so as to reduce
   the [principal amount] [number] of Warrant Securities purchasable upon
   exercise of the Warrants or so as to increase the exercise price [If
   Warrants for Common Stock are offered: (other than as provided by
   Section 2.03)], (ii) shortens the  period of time during which the
   Warrants may be exercised, (iii) otherwise adversely affects the
   exercise rights of the Holders in any material respect, or (iv)
   reduces the number of unexercised Warrants the consent of the Holders
   of which is required for amendment of this Agreement or the Warrants.

        SECTION 5.02.  Merger, Consolidation, Sale, Transfer or
   Conveyance.  The Company may consolidate or merge with or into any
   other corporation or sell, lease, transfer or convey all or
   substantially all of its assets to any other corporation, provided

                                     15<PAGE>





   that (i) either (x) the Company is the continuing corporation or (y)
   the corporation (if other than the Company) that is formed by or
   results from any such consolidation or merger or that receives such
   assets is a corporation organized and existing under the laws of the
   United States of America or a state thereof and such corporation
   assumes the obligations of the Company with respect to the performance
   and observance of all of the covenants and conditions of this
   Agreement to be performed or observed by the Company and (ii) the
   Company or such successor corporation, as the case may be, must not
   immediately be in default under this Agreement.  If at any time there
   shall be any consolidation or merger or any sale, lease, transfer,
   conveyance or other disposition of all or substantially all of the
   assets of the Company, then in any such event the successor or
   assuming corporation shall succeed to and be substituted for the
   Company, with the same effect as if it had been named herein and in
   the Warrant Certificates as the Company; the Company shall thereupon
   be relieved of any further obligation hereunder or under the Warrants,
   and, in the event of any such sale, lease, transfer, conveyance (other
   than by way of lease) or other disposition, the Company as the
   predecessor corporation may thereupon or at any time thereafter be
   dissolved, wound up or liquidated.  Such successor or assuming
   corporation thereupon may cause to be signed, and may issue either in
   its own name or in the name of the Company, Warrant Certificates
   evidencing the Warrants not theretofore exercised, in exchange and
   substitution for the Warrant Certificates theretofore issued.  Such
   Warrant Certificates shall in all respects have the same legal rank
   and benefit under this Agreement as the Warrant Certificates
   evidencing the Warrants theretofore issued in accordance with the
   terms of this Agreement as though such new Warrant Certificates had
   been issued at the date of the execution hereof.  In any case of any
   such merger or consolidation or sale, lease, transfer, conveyance or
   other disposition of all or substantially all of the assets of the
   Company, such changes in phraseology and form (but not in substance)
   may be made in the new Warrant Certificates, as may be appropriate.

        SECTION 5.03.  Notices and Demands to the Company and Warrant
   Agent.  If the Warrant Agent shall receive any notice or demand
   addressed to the Company by the Holder [If Warrants are to be issued
   in Book-Entry form: or a Participant, as the case may be], the Warrant
   Agent shall promptly forward such notice or demand to the Company.

        SECTION 5.04.  Addresses.  Any communications from the Company to
   the Warrant Agent with respect to this Agreement shall be addressed to

   under United States Federal and state laws, which the Company may deem
   necessary or appropriate in connection with the issuance, sale,

   the issuance, sale, transfer and delivery of the Warrant Securities to

                     [SCHIFF HARDIN & WAITE LETTERHEAD]

                                May 13, 1998


   AAR CORP.
   One AAR Place
   1100 North Wood Dale Road
   Wood Dale, Illinois  60191

   Ladies and Gentlemen:

        We have acted as counsel to AAR CORP., a Delaware corporation
   (the "Company"), and are rendering this opinion in connection with the
   Registration Statement on Form S-3 (the "Registration Statement")
   being filed by the Company with the Securities and Exchange Commission
   under the Securities Act of 1933, as amended (the "Securities Act"),
   with respect to the Company's: (i) Common Stock, par value $1.00 per
   share (the "Common Stock"); (ii) Preferred Stock, par value $1.00 per
   share (the "Preferred Stock"); (iii) Depositary Shares representing
   shares of the Preferred Stock (the "Depositary Shares"); (iv) Debt
   Securities (the "Debt Securities"); and (v) Warrants to purchase
   Common Stock, Preferred Stock, Debt Securities, or Depositary Shares
   (the "Warrants"), all of which may be issued from time to time on a
   delayed or continuous basis pursuant to Rule 415 under the Securities
   Act at an aggregate initial offering price not to exceed $200,000,000.

        The Debt Securities may be issued pursuant to an Indenture
   between the Company and U.S. Bank Trust National Association (formerly
   known as First Trust, National Association, as successor in interest
   to Continental Bank, National Association), as Trustee, as
   supplemented (collectively, the "Indenture").  The Depositary Shares
   will be deposited under a Deposit Agreement between the Company and a
   bank or trust company as Depositary and evidenced by Depositary
   Receipts.  The Warrants will be issued either independently or
   together with Common Stock, Preferred Stock, Depositary Shares, or
   Debt Securities and will be issued pursuant to a Warrant Agreement
   between the Company and a Warrant Agent.

        In connection with our opinion, we have examined the Registration
   Statement, including the exhibits thereto, and such other documents,
   corporate records, and instruments and have examined such laws and
   regulations as we have deemed necessary for the purposes of this
   opinion.  Based upon such examination, we are of the following
   opinions: 

        1.   The Company has been duly incorporated and is a validly
   existing corporation under the laws of the State of Delaware.

        2.   The Common Stock has been duly authorized and will be
   validly issued, fully paid, and nonassessable at such time as:  (i)
   the Registration Statement has become effective under the Securities<PAGE>





   Act, (ii) the terms of the issuance and sale of the Common Stock have
   been duly established in conformity with resolutions of the Board of
   Directors of the Company and the Company's Restated Certificate of
   Incorporation and By-laws, and (iii) the Common Stock has been duly
   issued and sold as contemplated by the Registration Statement and the
   Company's Restated Certificate of Incorporation and By-laws.

        3.   The Preferred Stock has been duly authorized and will be
   validly issued, fully paid, and nonassessable at such time as:  (i)
   the Registration Statement has become effective under the Securities
   Act, (ii) an appropriate Certificate or Certificates of Designations
   relating to a class or series of the Preferred Stock to be sold under
   the Registration Statement have been duly authorized and adopted and
   filed with the Secretary of State of the State of Delaware, (iii) the
   terms of the issuance and sale of shares of such class or series of
   Preferred Stock have been duly established in conformity with
   resolutions of the Board of Directors of the Company and the Company's
   Restated Certificate of Incorporation (including the Certificate or
   Certificates of Designation) and By-laws, and (iv) the shares of such
   class or series of Preferred Stock have been duly issued and sold as
   contemplated by the Registration Statement and the Company's Restated
   Certificate of Incorporation (including the Certificate or
   Certificates of Designation) and By-laws.

        4.   The Depositary Shares will be validly issued and the
   Depositary Receipts will entitle the holders thereof to the rights
   specified in the Depositary Shares and the Deposit Agreement, subject
   to bankruptcy, insolvency, fraudulent transfer, reorganization,
   moratorium and similar laws of general applicability relating to or
   affecting creditors' rights and to general equity principles at such
   time as:  (i) the Registration Statement has become effective under
   the Securities Act, (ii) the Deposit Agreement relating to the
   Depositary Shares has been duly authorized, executed and delivered,
   (iii) the terms of the Depositary Shares and of their issuance and
   sale have been duly established in conformity with resolutions of the
   Board of Directors of the Company and the Deposit Agreement, (iv) the
   class or series of Preferred Stock that is represented by the
   Depositary Shares has been duly authorized, validly issued and
   delivered to the Depositary, (v) the Depositary Receipts evidencing
   the Depositary Shares have been duly executed, countersigned and
   issued against deposit of the class or series of Preferred Stock in
   accordance with the Deposit Agreement, and (vi) the Depositary Shares
   have been duly issued and sold as contemplated by the Registration
   Statement and the Deposit Agreement.

        5.   The Debt Securities will be valid and legally binding
   obligations of the Company, subject to bankruptcy, insolvency,
   fraudulent transfer, reorganization, moratorium and similar laws of
   general applicability relating to or affecting creditors' rights and
   to general equity principles at such time as:  (i) the Registration
   Statement has become effective under the Securities Act, (ii) the
   terms of the Debt Securities and of their issuance and sale have been
   duly established in conformity with resolutions of the Board of
   Directors of the Company and the Indenture, (iii) the Debt Securities<PAGE>





   have been duly executed and authenticated in accordance with the
   Indenture, and (iv) the Debt Securities have been duly issued and sold
   as contemplated by the Registration Statement and the Indenture.

        6.   The Warrants will be valid and legally binding obligations
   of the Company, subject to bankruptcy, insolvency, fraudulent
   transfer, reorganization, moratorium and similar laws of general
   applicability relating to or affecting creditors' rights and to
   general equity principles at such time as:  (i) the Registration
   Statement has become effective under the Securities Act, (ii) the
   Warrant Agreement relating to the Warrants has been duly authorized,
   executed, and delivered, (iii) the terms of the Warrants and of their
   issuance and sale have been duly established in conformity with
   resolutions of the Board of Directors of the Company and the Warrant
   Agreement, (iv) the Warrants have been duly executed and countersigned
   in accordance with the Warrant Agreement and, (v) the Warrants have
   been duly issued and sold as contemplated by the Registration
   Statement and the Warrant Agreement.

        We express opinions herein with respect to the applicability of
   the laws of the State of Illinois, the United States Federal laws and
   the General Corporation Law of Delaware, and we express no opinion as
   to the laws of any other jurisdiction. 

        We have relied as to certain matters on information obtained from
   public officials, officers of the Company, and other sources believed
   by us to be responsible, and we have assumed that the Deposit
   Agreement will be duly authorized, executed, and delivered by the
   Depositary thereunder, and that the Warrant Agreement will be duly
   authorized, executed, and delivered by the Warrant Agent thereunder,
   assumptions which we have not independently verified.

        We hereby consent to the use of this opinion for filing with the
   Registration Statement as Exhibit 5.1 thereto and the reference to us
   under the caption  Legal Opinions  in the Prospectus contained in the
   Registration Statement.

                                 Very truly yours,

                                 SCHIFF HARDIN & WAITE
