                                  CRIIMI MAE
 
  CRIIMI MAE is a full service commercial mortgage company structured as a
self-administered real estate investment trust ("REIT"). CRIIMI MAE's
portfolio of assets consists primarily of non-investment grade subordinated
securities backed by first mortgage loans on multifamily and other commercial
real estate ("Subordinated CMBS") and interests in government insured or
guaranteed mortgages secured by multifamily housing complexes located
throughout the United States. CRIIMI MAE believes that its concentration on
acquiring Subordinated CMBS and originating commercial mortgage loans for its
own securitization program, together with its expertise as an underwriter and
servicer, enable CRIIMI MAE to take advantage of the rapid growth in the
securitization of debt backed by income-producing commercial real estate.
CRIIMI MAE is one of the largest publicly traded REITs focused primarily on
the acquisition of Subordinated CMBS. In addition, CRIIMI MAE provides certain
servicing functions, including acting as the special servicer for the
commercial mortgage loans underlying its Subordinated CMBS portfolio, with
respect to commercial mortgage assets.
 
                                USE OF PROCEEDS
 
  Unless otherwise specified in the applicable Prospectus Supplement for any
offering of Securities, CRIIMI MAE intends to use the majority of the net
proceeds from the sale of Securities (i) to acquire additional mortgage
assets, primarily Subordinated CMBSs, (ii) to sponsor and/or participate in
collateralized mortgage obligation programs, and (iii) for other general
corporate purposes, including working capital. Pending their use for the
foregoing purposes, the net proceeds may be invested in short term, interest-
bearing accounts and/or used to pay down debt on a temporary basis.

*  Prior to the offering of Series A Cumulative Convertible Preferred Stock on

   Shares.
 
  For purposes of computing these ratios, earnings consist of CRIIMI MAE's
consolidated net income, plus fixed charges, extraordinary items, loss from
investment in limited partnerships and dividends on Preferred Shares. Fixed
charges and Preferred Share dividends consist of gross interest cost,
including amortization of debt cost, discount or premium and adjustment to
hedges for valuation and sales, and dividends on Preferred Shares.

issued, a description of their terms (as well as the form of Debt Securities)
will be filed by CRIIMI MAE as an exhibit to a current report on Form 8-K and
incorporated herein by reference.
 
  When issued, the Debt Securities will be direct obligations of CRIIMI MAE
and may be either senior Debt Securities ("Senior Debt Securities") or
subordinated Debt Securities ("Subordinated Debt Securities"). The
indebtedness represented by Subordinated Debt Securities, as set forth below
under "--Subordination," will be subordinate in right of payment to Senior
Debt Securities and other senior indebtedness of CRIIMI MAE. In addition to
the terms of the Indenture and any specific, express terms of the Debt
Securities described below, the issuance of the Debt Securities will be
limited by, and subject to certain terms of, CRIIMI MAE's existing financing
facilities. Senior Debt Securities and Subordinated Debt Securities will be
issued pursuant to separate indentures (respectively, a "Senior Indenture" and
a "Subordinated Indenture"), in each case between the Company and a Trustee.
 
TERMS
 
  The applicable Indenture may provide that the Debt Securities may be issued
without limit as to aggregate principal amount, in one or more series, in each
case as established from time to time in or pursuant to authority granted by a
resolution of the Board of Directors of CRIIMI MAE (the "Board") or as
established in one or more indentures supplemental to such Indenture. All Debt
Securities of one series need not be issued at the same time and, unless
otherwise provided, a series may be reopened, without the consent of the
holders of the Debt Securities of such series, for issuances of additional
Debt Securities of such series.
 
  The applicable Indenture may also provide that there may be more than one
Trustee thereunder, each with respect to one or more series of Debt
Securities. Any Trustee under the applicable Indenture may resign or be
removed with respect to one or more series of Debt Securities, and a successor
Trustee may be appointed to act with respect to such series. In the event that
two or more persons are acting as Trustee with respect to different series of
Debt Securities, each such Trustee shall be a Trustee of a trust under the
applicable Indenture separate and apart from the trust administered by any
other Trustee, and, except as otherwise indicated therein, any action
described therein to be taken by the Trustee may be taken by each such Trustee
with respect to, and only with respect to, the one or more series of Debt
Securities for which it is Trustee under the applicable Indenture.
 
  Reference is made to the Prospectus Supplement relating to the series of
Debt Securities being offered for the specific terms thereof, including:
 
    (1) the title of such Debt Securities and whether such Debt Securities
  are Senior Debt Securities or Subordinated Debt Securities;
 
    (2) the aggregate principal amount of such Debt Securities and any limit
  on such aggregate principal amount;
 
    (3) the percentage of the principal amount at which such Debt Securities

  of the principal amount thereof payable upon declaration of acceleration of
  the maturity thereof, or (if applicable) the portion of the principal
  amount of such Debt Securities that is convertible into Common Shares
  and/or Preferred Shares, or the method by which any such portion shall be
  determined;
 
    (4) if convertible, in connection with the preservation of CRIIMI MAE's
  status as a REIT, any applicable limitations on the ownership or
  transferability of the Common Shares and/or Preferred Shares into which
  such Debt Securities are convertible;
 
 
                                       5

    (5) the date or dates, or the method for determining such date or dates,
  on which the principal of such Debt Securities will be payable;
 
    (6) the rate or rates (which may be fixed or variable), or the method by
  which such rate or rates shall be determined, at which such Debt Securities
  will bear interest, if any;
 
    (7) the date or dates, or the method for determining such date or dates,
  from which any such interest will accrue, the interest payment dates on
  which any such interest will be payable, the regular record dates for such

  determined, the persons to whom such interest shall be payable, and the
  basis upon which interest shall be calculated if other than that of a 360-
  day year of twelve 30-day months;
 
    (8) the place or places where the principal of (and premium, if any) and
  interest, if any, on such Debt Securities will be payable, where such Debt
  Securities may be surrendered for conversion or registration of transfer or
  exchange and where notices or demands to or upon CRIIMI MAE in respect of
  such Debt Securities and the applicable Indenture may be served;
 
    (9) the period or periods within which, the price or prices at which and
  the other terms and conditions upon which such Debt Securities may be
  redeemed, as a whole or in part, at the option of CRIIMI MAE, if CRIIMI MAE
  is to have such an option;
 
    (10) the obligation, if any, of CRIIMI MAE to redeem, repay or purchase
  such Debt Securities pursuant to any sinking fund or analogous provision or
  at the option of a holder thereof, and the period or periods within which,
  the price or prices at which and the other terms and conditions upon which
  such Debt Securities will be redeemed, repaid or purchased, as a whole or
  in part, pursuant to such obligation;
 
    (11) if other than U.S. dollars, the currency or currencies in which such
  Debt Securities are denominated and payable, which may be a foreign
  currency or units of two or more foreign currencies or a composite currency
  or currencies, and the terms and conditions relating thereto;
 
    (12) whether the amount of payments of principal of (and premium, if any)
  or interest, if any, on such Debt Securities may be determined with
  reference to an index, formula or other method (which index, formula or
  method may, but need not be, based on a currency, currencies, currency unit
  or units or composite currency or currencies) and the manner in which such
  amounts shall be determined;
 
    (13) whether such Debt Securities will be issued in the form of one or
  more global securities and whether such global securities are to be
  issuable in a temporary global form or permanent global form;
 
    (14) any additions to, modifications of or deletions from the terms of
  such Debt Securities with respect to the events of default or covenants set
  forth in the applicable Indenture;
 
    (15) any provision for collateral security for repayment of such Debt
  Securities;
 
    (16) whether such Debt Securities will be issued in certificated or book-
  entry form;
 
    (17) whether such Debt Securities will be in registered or bearer form
  and, if in registered form, the denominations thereof if other than $1,000
  and any integral multiple thereof and, if in bearer form, the denominations
  thereof and terms and conditions relating thereto;
 
    (18) the applicability, if any, of the defeasance and covenant defeasance
  provisions of the applicable Indenture;
 
    (19) the terms, if any, upon which such Debt Securities may be
  convertible into Common Shares and/or Preferred Shares and the terms and
  conditions upon which such conversion will be effected, including, without
  limitation, the initial conversion price or rate and the conversion period;
 
    (20) whether and under what circumstances CRIIMI MAE will pay additional
  amounts on such Debt Securities in respect of any tax, assessment or
  governmental charge and, if so, whether CRIIMI MAE will have the option to
  redeem such Debt Securities in lieu of making such payment; and
 
    (21) any other terms of such Debt Securities not inconsistent with the
  provisions of the applicable Indenture.
 
 
                                       6
<PAGE>
 
  The Debt Securities may provide for less than the entire principal amount
thereof to be payable upon declaration of acceleration of the maturity thereof
("Original Issue Discount Securities") or that the principal amount thereof
payable at their stated maturity may be more or less than the principal amount
thereof at original issuance ("Indexed Securities"). Special U.S. federal
income tax, accounting and other considerations applicable to Original Issue
Discount Securities or Indexed Securities will be described in the applicable
Prospectus Supplement.
 
  Except as may be set forth in any Prospectus Supplement, the Debt Securities
will not contain any provisions that would limit the ability of CRIIMI MAE to
incur indebtedness or that would afford holders of Debt Securities protection
in the event of a highly leveraged or similar transaction involving CRIIMI MAE
or in the event of a change of control. Restrictions on ownership and
transfers of CRIIMI MAE's Common Shares and Preferred Shares are designed to
preserve its status as a REIT and, therefore, may act to prevent or hinder a
change of control. See "Description of Capital Stock." Reference is made to
the applicable Prospectus Supplement for information with respect to any
deletions from, modifications of, or additions to, the events of default or
covenants of CRIIMI MAE that are described below, including any addition of a
covenant or other provision providing event risk or similar protection.
 
DENOMINATIONS, INTEREST, REGISTRATION AND TRANSFER
 
  Unless otherwise described in the applicable Prospectus Supplement, the Debt
Securities of any series will be issuable in denominations of $1,000 and
integral multiples thereof.
 
  Unless otherwise specified in the applicable Prospectus Supplement, the
principal of (and applicable premium, if any) and interest on any series of
Debt Securities will be payable at the corporate trust office of the Trustee;
provided that, at the option of CRIIMI MAE, payment of interest may be made by
check mailed to the address of the person entitled thereto as it appears in
the register to be maintained by the Trustee or by wire transfer of funds to
such person at an account maintained within the United States.
 
  Any interest not punctually paid or duly provided for on any interest
payment date with respect to a Debt Security ("Defaulted Interest") will
forthwith cease to be payable to the holder thereof on the applicable record
date and may either be paid to the person in whose name such Debt Security is
registered at the close of business on a special record date (the "Special
Record Date") for the payment of such Defaulted Interest to be fixed by the
applicable Trustee, notice whereof shall be given to each holder of such Debt
Security not less than 10 days prior to such Special Record Date, or may be
paid at any time in any other lawful manner, all as more completely described
in the applicable Indenture.
 
  Subject to certain limitations imposed upon Debt Securities issued in book-
entry form, the Debt Securities of any series will be exchangeable for other
Debt Securities of the same series and of a like aggregate principal amount
and tenor of different authorized denominations upon surrender of such Debt
Securities at the corporate trust office of the applicable Trustee. In
addition, subject to certain limitations imposed upon Debt Securities issued
in book-entry form, the Debt Securities of any series may be surrendered for
conversion or registration of transfer thereof at the corporate trust office
of the applicable Trustee. Every Debt Security tendered for conversion,
registration of transfer or exchange shall be duly endorsed or accompanied by
a written instrument of transfer. No service charge will be made for any
registration of transfer or exchange of any Debt Securities, but CRIIMI MAE
may require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith. If the applicable Prospectus
Supplement refers to any transfer agent (in addition to the applicable
Trustee) initially designated by CRIIMI MAE with respect to any series of Debt
Securities, CRIIMI MAE may at any time rescind the designation of any such
transfer agent or approve a change in the location through which any such
transfer agent acts, except that CRIIMI MAE will be required to maintain a
transfer agent in each place of payment for such series of Debt Securities.
CRIIMI MAE may at any time designate additional transfer agents with respect
to any series of Debt Securities.
 
 
                                       7
<PAGE>
 
  To protect CRIIMI MAE's status as a REIT, CRIIMI MAE may refuse to effect a
transfer of Debt Securities if, as a result of such transfer, any person would
beneficially own, either directly or indirectly, more than 9.8% of CRIIMI
MAE's outstanding capital stock. Neither CRIIMI MAE nor any Trustee shall be
required to (i) issue, register the transfer of or exchange Debt Securities of
any series during a period beginning at the opening of business 15 days before
any selection of Debt Securities of that series to be redeemed and ending at
the close of business on the day of mailing of the relevant notice of
redemption; (ii) register the transfer of or exchange any Debt Security, or
portion thereof, called for redemption, except the unredeemed portion of any
Debt Security being redeemed in part; or (iii) for Debt Securities repayable
at the option of the holder, issue, register the transfer of or exchange any
Debt Security that has been surrendered for repayment at the option of the
holder, except the portion, if any, of such Debt Security not to be so repaid.
 
MERGER, CONSOLIDATION OR SALE
 
  Each Indenture will provide that CRIIMI MAE may consolidate with, or sell,
lease or convey all or substantially all of its assets to, or merge with or
into, any other corporation or trust or other entity provided that (a) either
CRIIMI MAE shall be the continuing corporation, or the successor corporation
(if other than CRIIMI MAE) formed by or resulting from any such consolidation
or merger or which shall have received the transfer of such assets and shall
be an entity organized and existing under the laws of the United States or a
state thereof and the successor entity shall expressly assume payment of the
principal of (and premium, if any) and interest on all of the Debt Securities
and the due and punctual performance and observance of all of the covenants
and conditions contained in the applicable Indenture; (b) immediately after
giving effect to such transaction and treating any indebtedness that becomes
an obligation of CRIIMI MAE or any subsidiary as a result thereof as having
been incurred by CRIIMI MAE or such subsidiary at the time of such
transaction, no event of default under the applicable Indenture, and no event
which, after notice or the lapse of time, or both, would become such an event
of default, shall have occurred and be continuing; and (c) an officers'
certificate and legal opinion covering such conditions shall be delivered to
each Trustee.
 
CERTAIN COVENANTS
 
  Existence. Except as permitted under "--Merger, Consolidation or Sale,"
CRIIMI MAE will do or cause to be done all things necessary to preserve and
keep in full force and effect its corporate existence, rights (charter and
statutory) and franchises; provided, however, that CRIIMI MAE shall not be
required to preserve any right or franchise if it determines that the
preservation thereof is no longer desirable in the conduct of its business and
that the loss thereof is not disadvantageous in any material respect to the
holders of the Debt Securities.
 
  Maintenance of Properties. CRIIMI MAE will cause all of its material
properties used or useful in the conduct of its business or the business of
any subsidiary to be maintained and kept in good condition, repair and working
order and supplied with all necessary equipment and will cause to be made all
necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of CRIIMI MAE may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that CRIIMI MAE and its
subsidiaries shall not be prevented from discontinuing the operation and
maintenance of any such properties if such discontinuance is in the judgment
of CRIIMI MAE desirable in the conduct of its business and not disadvantageous
in any material respect to the holders of the Debt Securities.
 
  Payment of Taxes and Other Claims. CRIIMI MAE will pay or discharge or cause
to be paid or discharged, before the same shall become delinquent, (i) all
taxes, assessments and governmental charges levied or imposed upon it or any
subsidiary or upon the income, profits or property of CRIIMI MAE or any
subsidiary, and (ii) all lawful claims for labor, materials and supplies
which, if unpaid, might by law become a lien upon the property of CRIIMI MAE
or any subsidiary; provided, however, that CRIIMI MAE shall not be required to
pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings.
 
  Additional Covenants. Any additional covenants of CRIIMI MAE with respect to
any series of Debt Securities will be set forth in the Prospectus Supplement
relating thereto.

EVENTS OF DEFAULT, NOTICE AND WAIVER
  Each Indenture will describe specific "Events of Default" with respect to
any series of Debt Securities issued thereunder. Such "Events of Default" are
likely to include (with grace and cure periods): (a) default for 30 days in
the payment of any installment of interest on any Debt Security of such
series; (b) default in the payment of the principal of (or premium, if any,
on) any Debt Security of such series when due and payable, at maturity, upon
redemption or otherwise which continues for five business days; (c) default in
making any sinking fund payment as required for any Debt Security of such
series which continues for five business days; (d) default in the performance
or breach of any other covenant or warranty of CRIIMI MAE contained in the
applicable Indenture (other than a covenant added to such Indenture solely for
the benefit of a series of Debt Securities issued thereunder other than such
series), continued for 60 days after written notice as provided in the
applicable Indenture; (e) a default not being contested in good faith by
CRIIMI MAE under any bond, debenture, note or other evidence of indebtedness
for money borrowed by CRIIMI MAE (including obligations under leases required
to be capitalized on the balance sheet of the lessee under generally accepted
accounting principles but not including any indebtedness or obligations for
which recourse is limited to property purchased) in an aggregate principal
amount in excess of $10,000,000 or under any mortgage, indenture or instrument
under which there may be issued or by which there may be secured or evidenced
any indebtedness for money borrowed by CRIIMI MAE (including such leases but
not including such indebtedness or obligations for which recourse is limited
to property purchased) in an aggregate principal amount in excess of
$10,000,000 by CRIIMI MAE, whether such indebtedness now exists or shall
hereafter be created which default shall have resulted in such indebtedness
becoming or being declared due and payable prior to the date on which it would
otherwise have become due and payable or such obligations being accelerated,
without such acceleration having been rescinded or annulled; (f) certain
events of bankruptcy, insolvency or reorganization, or court appointment of a
receiver, liquidator or trustee of CRIIMI MAE or any Significant Subsidiary or
either of its properties; and (g) any other Event of Default provided with
respect to a particular series of Debt Securities. The term "Significant
Subsidiary" means each significant subsidiary (as defined in Regulation S-X
promulgated under the Securities Act) of CRIIMI MAE.
 
  If an Event of Default under an Indenture with respect to Debt Securities of
any series at the time outstanding occurs and is continuing, then in every
such case the applicable Trustee or the holders of not less than 25% in
principal amount of the outstanding Debt Securities of that series may declare
the principal amount (or, if the Debt Securities of that series are Original
Issue Discount Securities or Indexed Securities, such portion of the principal
amount as may be specified in the terms thereof) of all the Debt Securities of
that series to be due and payable immediately by written notice thereof to
CRIIMI MAE (and to the applicable Trustee if given by the holders). However,
at any time after such a declaration of acceleration with respect to Debt
Securities of such series (or of all Debt Securities then outstanding under
the applicable Indenture, as the case may be) has been made, but before a
judgment or decree for payment of the money due has been obtained by the
applicable Trustee, the holders of not less than a majority in principal
amount of outstanding Debt Securities of such series (or of all Debt
Securities then outstanding under the applicable Indenture, as the case may
be) may rescind and annul such declaration and its consequences if (a) CRIIMI
MAE shall have paid or deposited with the applicable Trustee all required
payments of the principal of (and premium, if any) and interest on the Debt
Securities of such series (or of all Debt Securities then outstanding under
the applicable Indenture, as the case may be), plus certain fees, expenses,
disbursements and advances of the applicable Trustee and (b) all Events of
Default, other than the non-payment of accelerated principal (or specified
portion thereof), with respect to Debt Securities of such series (or of all
Debt Securities then outstanding under the applicable Indenture, as the case
may be) have been cured or waived as provided in the applicable Indenture.
Each Indenture will also provide that the holders of not less than a majority
in principal amount of the outstanding Debt Securities of any series (or of
all Debt Securities then outstanding under the applicable Indenture, as the
case may be) may waive any past default with respect to such series and its
consequences, except a default (x) in the payment of the principal of (or
premium, if any) or interest on any Debt Security of such series or (y) in
respect of a covenant or provision contained in the applicable Indenture that
cannot be modified or amended without the consent of the holder of each
outstanding Debt Security affected thereby.
 
  The applicable Trustee will be required to give notice to the holders of
Debt Securities within 90 days of a default under the applicable Indenture
unless such default shall have been cured or waived; provided, however,
 
                                       9
<PAGE>
 
that such Trustee may withhold notice to the holders of any series of Debt
Securities of any default with respect to such series (except a default in the
payment of the principal of (or premium, if any) or interest on any Debt
Security of such series or in the payment of any sinking fund installment in
respect of any Debt Security of such series) if designated officers of such
Trustee consider such withholding to be in the interest of such holders.
 
  The right of any holder to institute a proceeding with respect to an
Indenture will be subject to certain conditions precedent including notice and
indemnity to the applicable Trustee, but the holder has an absolute right to
receipt of principal of (and premium, if any) and interest on such holder's
Debt Security on or after the respective due dates expressed in the Debt
Security, and to institute suit for the enforcement of any such payments.
 
  Subject to provisions in the Indenture relating to its duties in case of
default, no Trustee will be under an obligation to exercise any of its rights
or powers under such Indenture at the request or direction of any holders of
any series of Debt Securities then outstanding under such Indenture, unless
such holders shall have offered to the applicable Trustee thereunder
reasonable security or indemnity. The holders of not less than a majority in
aggregate principal amount of the outstanding Debt Securities of any series
(or of all Debt Securities then outstanding under the applicable Indenture, as
the case may be) shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the applicable Trustee,
or of exercising any trust or power conferred upon such Trustee. However, each
Trustee may refuse to follow any direction which is in conflict with any law
or the applicable Indenture, which may involve such Trustee in personal
liability or which may be unduly prejudicial to the holders of Debt Securities
of such series not joining therein.
 
  Within 120 days after the close of each fiscal year, CRIIMI MAE will be
required to deliver to each Trustee a certificate, signed by one of several
specified officers, stating whether or not such officer has knowledge of any
default under the applicable Indenture and, if so, specifying each such
default and the nature and status thereof.
 
MODIFICATION OF THE INDENTURE
 
  Modifications and amendments of an Indenture may be made only with the
consent of the holders of not less than a majority in aggregate principal
amount of all outstanding Debt Securities issued under the Indenture which are
affected by such modification or amendment; provided, however, that no such
modification or amendment may, without the consent of the holder of each such
Debt Security affected thereby, (a) change the stated maturity of the
principal of, or any installment of interest (or premium, if any) on, any such
Debt Security; (b) reduce the principal amount of, or the rate or amount of
interest on, or any premium payable on redemption of, any such Debt Security,
or reduce the amount of principal of an Original Issue Discount Security that
would be due and payable upon declaration of acceleration of the maturity
thereof or would be provable in bankruptcy, or adversely affect any right of
repayment of the holder of any such Debt Security; (c) change the place of
payment, or the coin or currency, for payment of principal of, premium, if
any, or interest on any such Debt Security; (d) impair the right to institute
suit for the enforcement of any payment on or with respect to any such Debt
Security; (e) reduce the above-stated percentage of outstanding Debt
Securities of any series necessary to modify or amend the Indenture, to waive
compliance with certain provisions thereof or certain defaults and
consequences thereunder or to reduce the quorum or voting requirements set
forth in the Indenture; or (f) modify any of the foregoing provisions or any
of the provisions relating to the waiver of certain past defaults or certain
covenants, except to increase the required percentage to effect such action or
to provide that certain other provisions may not be modified or waived without
the consent of the holder of such Debt Security.
 
  The holders of not less than a majority in principal amount of outstanding
Debt Securities issued under an Indenture have the right to waive compliance
by CRIIMI MAE with certain covenants in such Indenture.
 
  Modifications and amendments of an Indenture may be made by CRIIMI MAE and
the respective Trustee thereunder without the consent of any holder of Debt
Securities for any of the following purposes: (i) to evidence the succession
of another person to CRIIMI MAE as obligor under such Indenture; (ii) to add
to the covenants of CRIIMI MAE for the benefit of the holders of all or any
series of Debt Securities or to surrender any right or power conferred upon
CRIIMI MAE in such Indenture; (iii) to add Events of Default for the benefit
of the
 
                                      10
<PAGE>
 
holders of all or any series of Debt Securities; (iv) to add or change any
provisions of the Indenture to facilitate the issuance of, or to liberalize
certain terms of, Debt Securities in bearer form, or to permit or facilitate
the issuance of Debt Securities in uncertificated form, provided that such
action shall not adversely affect the interests of the holders of the Debt
Securities of any series in any material respect; (v) to change or eliminate
any provisions of the Indenture, provided that any such change or elimination
shall become effective only when there are no Debt Securities outstanding of
any series created prior thereto which are entitled to the benefit of such
provision; (vi) to secure the Debt Securities; (vii) to establish the form or
terms of Debt Securities of any series, including the provisions and
procedures, if applicable, for the conversion of such Debt Securities into
Common Shares and/or Preferred Shares; (viii) to provide for the acceptance of
appointment by a successor Trustee or facilitate the administration of the
trusts under the Indenture by more than one Trustee; (ix) to cure any
ambiguity, defect or inconsistency in the Indenture, provided that such action
shall not adversely affect the interests of holders of Debt Securities of any
series issued under such Indenture in any material respect; or (x) to
supplement any of the provisions of the Indenture to the extent necessary to
permit or facilitate defeasance and discharge of any series of such Debt
Securities, provided that such action shall not adversely affect the interests
of the holders of the Debt Securities of any series in any material respect.
 
  Each Indenture will provide that in determining whether the holders of the
requisite principal amount of outstanding Debt Securities of a series have
given any request, demand, authorization, direction, notice, consent or waiver
thereunder or whether a quorum is present at a meeting of holders of Debt
Securities, (i) the principal amount of an Original Issue Discount Security
that shall be deemed to be outstanding shall be the amount of the principal
thereof that would be due and payable as of the date of such determination
upon declaration of acceleration of the maturity thereof, (ii) the principal
amount of a Debt Security denominated in a foreign currency that shall be
deemed outstanding shall be the U.S. dollar equivalent, determined on the
issue date for such Debt Security, of the principal amount (or, in the case of
an Original Issue Discount Security, the U.S. dollar equivalent on the issue
date of such Debt Security of the amount determined as provided in (i) above),
(iii) the principal amount of an Indexed Security that shall be deemed
outstanding shall be the principal face amount of such Indexed Security at
original issuance, unless otherwise provided with respect to such Indexed
Security pursuant to the Indenture, and (iv) Debt Securities owned by CRIIMI
MAE or any other obligor upon the Debt Securities or any affiliate of CRIIMI
MAE or of such other obligor shall be disregarded.
 
  Each Indenture will contain provisions for convening meetings of the holders
of Debt Securities of a series. A meeting may be called at any time by the
applicable Trustee, and also, upon request, by CRIIMI MAE or the holders of at
least 25% in principal amount of the outstanding Debt Securities of such
series, in any such case upon notice given as provided in the applicable
Indenture. Except for any consent that must be given by the holder of each
Debt Security affected by certain modifications and amendments of the
Indenture, any resolution presented at a meeting or adjourned meeting duly
reconvened at which a quorum is present may be adopted by the affirmative vote
of the holders of a majority in principal amount of the outstanding Debt
Securities of that series; provided, however, that, except as referred to
above, any resolution with respect to any request, demand, authorization,
direction, notice, consent, waiver or other action that may be made, given or
taken by the holders of a specified percentage, which is less than a majority,
in principal amount of the outstanding Debt Securities of a series may be
adopted at a meeting or adjourned meeting duly reconvened at which a quorum is
present by the affirmative vote of the holders of such specified percentage in
principal amount of the outstanding Debt Securities of that series. Any
resolution passed or decision taken at any meeting of holders of Debt
Securities of any series duly held in accordance with the applicable Indenture
will be binding on all holders of Debt Securities of that series. The quorum
at any meeting called to adopt a resolution, and at any reconvened meeting,
will be persons holding or representing a majority in principal amount of the
outstanding Debt Securities of a series; provided, however, that if any action
is to be taken at such meeting with respect to a consent or waiver which may
be given by the holders of not less than a specified percentage in principal
amount of the outstanding Debt Securities of a series, the persons holding or
representing such specified percentage in principal amount of the outstanding
Debt Securities of such series will constitute a quorum.
 
  Notwithstanding the foregoing provisions, if any action is to be taken at a
meeting of holders of Debt Securities of any series with respect to any
request, demand, authorization, direction, notice, consent, waiver or
 
                                      11
<PAGE>
 
other action that the applicable Indenture expressly provides may be made,
given or taken by the holders of a specified percentage in principal amount of
all outstanding Debt Securities affected thereby, or of the holders of such
series and one or more additional series: (i) there shall be no minimum quorum
requirement for such meeting and (ii) the principal amount of the outstanding
Debt Securities of such series that vote in favor of such request, demand,
authorization, direction, notice, consent, waiver or other action shall be
taken into account in determining whether such request, demand, authorization,
direction, notice, consent, waiver or other action has been made, given or
taken under the Indenture.

  Upon any distribution to creditors of the Company in a liquidation,
dissolution or reorganization, the payment of the principal of and interest on
any Subordinated Debt Securities will be subordinated to the extent provided
in the applicable Indenture in right of payment to the prior payment in full
of all Senior Debt Securities and other senior indebtedness. No payment of
principal or interest will be permitted to be made on Subordinated Debt
Securities at any time if a default in Senior Debt Securities exists that
permits the holders of such Senior Debt Securities to accelerate their
maturity and the default is the subject of judicial proceedings or the Company
receives notice of the default. After all Senior Debt Securities are paid in
full and until the Subordinated Debt Securities are paid in full, holders of
Subordinated Debt Securities will be subrogated to the right of holders of
Senior Debt Securities to the extent that distributions otherwise payable to
holders of Subordinated Debt Securities have been applied to the payment of
Senior Debt Securities. By reason of such subordination, in the event of a
distribution of assets upon insolvency, certain general creditors of the
Company may recover more, ratably, than holders of Subordinated Debt
Securities. If this Prospectus is being delivered in connection with a series
of Subordinated Debt Securities, the accompanying Prospectus Supplement or the
information incorporated herein by reference will contain the approximate
amount of Senior Debt Securities outstanding as of the end of the Company's
most recent fiscal quarter.
 
DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE
 
  Under the Indentures, CRIIMI MAE may be permitted to discharge certain
obligations to holders of any series of Debt Securities issued thereunder that
have not already been delivered to the applicable Trustee for cancellation and
that either have become due and payable or will become due and payable within
one year (or scheduled for redemption within one year) by irrevocably
depositing with the applicable Trustee, in trust, funds in such currency or
currencies, currency unit or units or composite currency or currencies in
which such Debt Securities are payable in an amount sufficient to pay the
entire indebtedness on such Debt Securities in respect of principal (and
premium, if any) and interest to the date of such deposit (if such Debt
Securities have become due and payable) or to the stated maturity or
redemption date, as the case may be.
 
  Each Indenture will provide that, under certain circumstances, CRIIMI MAE
may elect either (a) to defease and be discharged from any and all obligations
with respect to such Debt Securities (except for the obligation to pay
additional amounts, if any, upon the occurrence of certain events of tax,
assessment or governmental charge with respect to payments on such Debt
Securities and the obligations to register the transfer or exchange of such
Debt Securities, to replace temporary or mutilated, destroyed, lost or stolen
Debt Securities, to maintain an office or agency in respect of such Debt
Securities and to hold moneys for payment in trust) ("defeasance") or (b) to
be released from its obligations with respect to such Debt Securities under
the applicable Indenture or, under certain circumstances, its obligations with
respect to any other covenant, and any omission to comply with such
obligations shall not constitute a default or an Event of Default with respect
to such Debt Securities ("covenant defeasance"), in either case upon the
irrevocable deposit by CRIIMI MAE with the applicable Trustee, in trust, of an
amount, in such currency or currencies, currency unit or units or composite
currency or currencies in which such Debt Securities are payable at stated
maturity, or Government Obligations (as defined below), or both, applicable to
such Debt Securities which through the scheduled payment of principal and
interest in accordance with their terms will provide money in an amount
sufficient to pay the principal of (and premium, if any) and interest on such
Debt Securities, and any mandatory sinking fund or analogous payments thereon,
on the scheduled due dates therefor.
 
 
                                      12
<PAGE>
 
  Such a trust may be established only if, among other things, CRIIMI MAE has
delivered to the applicable Trustee an opinion of counsel (as specified in
each Indenture) to the effect that the holders of such Debt Securities will
not recognize income, gain or loss for U.S. federal income tax purposes as a
result of such defeasance or covenant defeasance and will be subject to U.S.
federal income tax on the same amounts, in the same manner and at the same
times as would have been the case if such defeasance or covenant defeasance
had not occurred, and such opinion of counsel, in the case of defeasance, must
refer to and be based upon a ruling of the Internal Revenue Service or a
change in applicable U.S. federal income tax law occurring after the date of
the Indenture.
 
  "Government Obligations" means securities which are (i) direct obligations
of the United States of America or the government which issued the foreign
currency in which the Debt Securities of a particular series are payable, for
the payment of which its full faith and credit is pledged or (ii) obligations
of a person controlled or supervised by and acting as an agency or
instrumentality of the United States of America or such government which
issued the foreign currency in which the Debt Securities of such series are
payable, the payment of which is unconditionally guaranteed as a full faith
and credit obligation by the United States of America or such other
government, which, in either case, are not callable or redeemable at the
option of the issuer thereof, and shall also include a depository receipt
issued by a bank or trust company as custodian with respect to any such
Government Obligation or a specific payment of interest on or principal of any
such Government Obligation held by such custodian for the account of the
holder of a depository receipt, provided that (except as required by law) such
custodian is not authorized to make any deduction from the amount payable to
the holder of such depository receipt from any amount received by the
custodian in respect of the Government Obligation or the specific payment of
interest on or principal of the Government Obligation evidenced by such
depository receipt.
 
  Unless otherwise provided in the applicable Prospectus Supplement, if after
CRIIMI MAE has deposited funds and/or Government Obligations to effect
defeasance or covenant defeasance with respect to Debt Securities of any
series, (a) the holder of a Debt Security of such series is entitled to, and
does, elect pursuant to the Indenture or the terms of such Debt Security to
receive payment in a currency, currency unit or composite currency other than
that in which such deposit has been made in respect of such Debt Security, or
(b) a Conversion Event (as defined below) occurs in respect of the currency,
currency unit or composite currency in which such deposit has been made, the
indebtedness represented by such Debt Security shall be deemed to have been,
and will be, fully discharged and satisfied through the payment of the
principal of (and premium, if any) and interest on such Debt Security as they
become due out of the proceeds yielded by converting the amount so deposited
in respect of such Debt Security into the currency, currency unit or composite
currency in which such Debt Security becomes payable as a result of such
election or such cessation of usage based on the applicable market exchange
rate. "Conversion Event" means the cessation of use of (i) a currency,
currency unit or composite currency both by the government of the country
which issued such currency and for the settlement of transactions by a central
bank or other public institutions of or within the international banking
community, (ii) the European Currency Unit ("ECU") both within the European
Monetary System established by the Resolution of December 5, 1978 of the
council of the European Economic Community, European Coal and Steel Community
and the European Atomic Energy Community (collectively, the "European
Communities") and for the settlement of transactions by public institutions of
or within the European Communities or (iii) any currency unit or composite
currency other than the ECU for the purposes for which it was established.
Unless otherwise provided in the applicable Prospectus Supplement, all
payments of principal of (and premium, if any) and interest on any Debt
Security that is payable in a foreign currency that ceases to be used by its
government of issuance shall be made in U.S. dollars.
 
  The applicable Prospectus Supplement may further describe the provisions, if
any, permitting such defeasance or covenant defeasance, including any
modifications of the provisions described above, with respect to the Debt
Securities of or within a particular series.
 
CONVERSION RIGHTS
 
  The terms and conditions, if any, upon which the Debt Securities are
convertible into Common Shares or Preferred Shares will be set forth in the
applicable Prospectus Supplement relating thereto. Such terms will
 
                                      13
<PAGE>
 
include whether such Debt Securities are convertible into Common Shares and/or
Preferred Shares, the conversion price (or manner of calculation thereof), the
conversion period, provisions as to whether conversion will be at the option
of the holders or CRIIMI MAE, the events requiring an adjustment of the
conversion price and provisions affecting conversion in the event of the
redemption of such Debt Securities.
 
  To protect CRIIMI MAE's status as a REIT, CRIIMI MAE may refuse to effect a
conversion of the Debt Securities if, as a result of such conversion, any
person would beneficially own, either directly or indirectly, more than 9.8%
of CRIIMI MAE's outstanding capital stock. See "Description of Capital Stock--
Common Shares--Restrictions on Ownership and Transfer."
 
GLOBAL SECURITIES
 
  The Debt Securities of a series may be issued in whole or in part in the
form of one or more global securities (the "Global Securities") that will be
deposited with, or on behalf of, a depositary identified in the applicable
Prospectus Supplement relating to such series. Global Securities may be issued
in either registered or bearer form and in either temporary or permanent form.
The specific terms of the depositary arrangement with respect to a series of
Debt Securities will be described in the applicable Prospectus Supplement
relating to such series.
 
                         DESCRIPTION OF CAPITAL STOCK
 
  The authorized capital stock of CRIIMI MAE comprises 60 million Common
Shares and 25 million Preferred Shares.
 
PREFERRED SHARES
 
  General. The following description of the Preferred Shares sets forth
certain general terms and provisions of the Preferred Shares to which any
Prospectus Supplement may relate. The statements below describing the
Preferred Shares are in all respects subject to and qualified in their
entirety by reference to the applicable provisions of CRIIMI MAE's Articles of
Incorporation, as amended (the "Articles of Incorporation") and Bylaws and
applicable articles supplementary relating to any offering of Preferred Shares
("Articles Supplementary"). If Preferred Shares are to be issued, a
description of the terms of such Preferred Shares (as well as the form of
Preferred Share certificate) will be filed by CRIIMI MAE as an exhibit to a
current report on Form 8-K and incorporated by reference.
 
  Terms. Subject to the limitations prescribed by the Articles of
Incorporation, the Board is authorized to fix the number of shares
constituting each series of Preferred Shares and the designations and powers,
preferences and relative, participating, optional or other special rights and
qualifications, limitations or restrictions thereof, including such provisions
as may be desired concerning voting, redemption, dividends, dissolution or the
distribution of assets, conversion or exchange, and such other subjects or
matters as may be fixed by resolution of the Board. The Preferred Shares will,
when issued, be fully paid and nonassessable by CRIIMI MAE and will have no
preemptive rights.
 
  Reference is made to the Prospectus Supplement relating to the Preferred
Shares offered thereby for specific terms, including:
 
    (1) The title and stated value of such Preferred Shares;
 
    (2) The number of such Preferred Shares offered, the liquidation
  preference per share and the offering price of such Preferred Shares;
 
    (3) The dividend rate(s), period(s) and/or payment date(s) or method(s)
  of calculation thereof applicable to such Preferred Shares;
 
    (4) The date from which dividends on such Preferred Shares shall
  accumulate, if applicable;
 
    (5) The procedures for any auction and remarketing, if any, for such
  Preferred Shares;
 
                                      14
<PAGE>
 
    (6) The provision for a sinking fund, if any, for such Preferred Shares;
 
    (7) The provision for redemption, if applicable, of such Preferred
  Shares;
 
    (8) Any listing of such Preferred Shares on any securities exchange;
 
    (9) The terms and conditions, if applicable, upon which such Preferred
  Shares will be convertible into Common Shares, including the conversion
  price (or manner of calculation thereof);
 
    (10) Any other specific terms, preferences, rights, limitations or
  restrictions of such Preferred Shares;
 
    (11) A discussion of federal income tax considerations applicable to such
  Preferred Shares;
 
    (12) The relative ranking and preferences of such Preferred Shares as to
  dividend rights and rights upon liquidation, dissolution or winding up of
  the affairs of CRIIMI MAE;
 
    (13) Any limitations on issuance of any series of Preferred Shares
  ranking senior to or on a parity with such series of Preferred Shares as to
  dividend rights and rights upon liquidation, dissolution or winding up of
  the affairs of CRIIMI MAE; and
 
    (14) Any limitations on direct or beneficial ownership and restrictions
  on transfer, in each case as may be appropriate to preserve the status of
  CRIIMI MAE as a REIT.
 
  Rank. Unless otherwise specified in the Prospectus Supplement, the Preferred
Shares will, with respect to dividend rights and rights upon liquidation,
dissolution or winding up of CRIIMI MAE, rank (i) senior to all classes or
series of Common Shares and to all equity securities ranking junior to such
Preferred Shares with respect to dividend rights or rights upon liquidation,
dissolution or winding up of CRIIMI MAE; (ii) on a parity with all equity
securities issued by CRIIMI MAE the terms of which specifically provide that
such equity securities rank on a parity with the Preferred Shares with respect
to dividend rights or rights upon liquidation, dissolution or winding up of
CRIIMI MAE; and (iii) junior to all equity securities issued by CRIIMI MAE the
terms of which specifically provide that such equity securities rank senior to
the Preferred Shares with respect to dividend rights or rights upon
liquidation, dissolution or winding up of CRIIMI MAE. The term "equity
securities" does not include convertible debt securities.
 
  Dividends. Holders of the Preferred Shares of each series will be entitled
to receive, when, as and if declared by the Board, out of assets of CRIIMI MAE
legally available for payment, cash dividends at such rates and on such dates
as will be set forth in the applicable Prospectus Supplement. Each such
dividend shall be payable to holders of record as they appear on the share
transfer books of CRIIMI MAE on such record dates as shall be fixed by the
Board.
 
  Dividends on any series of the Preferred Shares may be cumulative or non-
cumulative, as provided in the applicable Prospectus Supplement. Dividends, if
cumulative, will be cumulative from and after the date set forth in the
applicable Prospectus Supplement. If the Board fails to declare a dividend
payable on a dividend payment date on any series of the Preferred Shares for
which dividends are noncumulative, then the holders of such series of the
Preferred Shares will have no right to receive a dividend in respect of the
dividend period ending on such dividend payment date, and CRIIMI MAE will have
no obligation to pay the dividend accrued for such period, whether or not
dividends on such series are declared payable on any future dividend payment
date.
 
  If Preferred Shares of any series are outstanding, full dividends will not
be declared or paid or set apart for payment on the Preferred Shares of any
other series ranking, as to dividends, on a parity with the Preferred Shares
of such series, and no dividends will be declared or paid or set apart for
payment on the Preferred Shares of any other series ranking, as to dividends,
junior to the Preferred Shares of such series for any period unless (i) if
such series of Preferred Shares has a cumulative dividend, full cumulative
dividends have been or contemporaneously are declared and paid or declared and
a sum sufficient for the payment thereof set apart for such payment on the
Preferred Shares of such series for all past dividend periods and the then
current dividend period or (ii) if such series of Preferred Shares does not
have a cumulative dividend, full dividends for the then current dividend
period have been or contemporaneously are declared and paid or declared and a
sum sufficient for the payment thereof set apart for such payment on the
Preferred Shares of such series. When dividends are
 
                                      15
<PAGE>
 
not paid in full (or a sum sufficient for such full payment is not so set
apart) upon Preferred Shares of any series and the shares of any other series
of Preferred Shares ranking on a parity as to dividends with the Preferred
Shares of such series, all dividends declared upon Preferred Shares of such
series and any other series of Preferred Shares ranking on a parity as to
dividends with such Preferred Shares shall be declared pro rata so that the
amount of dividends declared per Preferred Share of such series and such other
series of Preferred Shares shall in all cases bear to each other the same
ratio that accrued dividends per share on the Preferred Shares of such series
(which shall not include any accumulation in respect of unpaid dividends for
prior dividend periods if such Preferred Shares do not have a cumulative
dividend) and such other series of Preferred Shares bear to each other.
 
  Except as provided in the immediately preceding paragraph, unless (i) if
such series of Preferred Shares has a cumulative dividend, full cumulative
dividends on the Preferred Shares of such series have been or
contemporaneously are declared and paid or declared and a sum sufficient for
the payment thereof set apart for payment for all past dividend periods and
the then current dividend period and (ii) if such series of Preferred Shares
does not have a cumulative dividend, full dividends on the Preferred Shares of
such series have been or contemporaneously are declared and paid or declared
and a sum sufficient for the payment thereof set apart for payment for the
then current dividend period, no dividends (other than in Common Shares or
other capital shares ranking junior to the Preferred Shares of such series as
to dividends and upon liquidation) shall be declared or paid or set aside for
payment or other distribution shall be declared or made upon the Common
Shares, or any other capital shares of CRIIMI MAE ranking junior to or on a
parity with the Preferred Shares of such series as to dividends or upon
liquidation, nor shall any Common Shares, or any other capital shares of
CRIIMI MAE ranking junior to or on a parity with the Preferred Shares of such
series as to dividends or upon liquidation be redeemed, purchased or otherwise
acquired for any consideration (or any moneys be paid to or made available for
a sinking fund for the redemption of any such shares) by CRIIMI MAE (except by
conversion into or exchange for other capital shares of CRIIMI MAE ranking
junior to the Preferred Shares of such series as to dividends and upon
liquidation).
 
  Any dividend payment made on shares of a series of Preferred Shares shall
first be credited against the earliest accrued but unpaid dividend due with
respect to shares of such series which remains payable.
 
  Redemption. If so provided in the applicable Prospectus Supplement, the
Preferred Shares will be subject to mandatory redemption or redemption at the
option of CRIIMI MAE, as a whole or in part, in each case upon the terms, at
the times and at the redemption prices set forth in such Prospectus
Supplement.
 
  The Prospectus Supplement relating to a series of Preferred Shares that is
subject to mandatory redemption will specify the number of such Preferred
Shares that shall be redeemed by CRIIMI MAE in each year commencing after a
date to be specified, at a redemption price per share to be specified,
together with an amount equal to all accrued and unpaid dividends thereon
(which shall not, if such Preferred Shares do not have a cumulative dividend,
include any accumulation in respect of unpaid dividends for prior dividend
periods) to the date of redemption. The redemption price may be payable in
cash or other property, as specified in the applicable Prospectus Supplement.
If the redemption price for Preferred Shares of any series is payable only
from the net proceeds of the issuance of capital shares of CRIIMI MAE, the
terms of such Preferred Shares may provide that, if no such capital shares
shall have been issued or to the extent the net proceeds from any issuance are
insufficient to pay in full the aggregate redemption price then due, such
Preferred Shares shall automatically and mandatorily be converted into the
applicable capital shares of CRIIMI MAE pursuant to conversion provisions
specified in the applicable Prospectus Supplement.
 
  Notwithstanding the foregoing, unless (i) if such series of Preferred Shares
has a cumulative dividend, full cumulative dividends on all shares of any
series of Preferred Shares shall have been or contemporaneously are declared
and paid or declared and a sum sufficient for the payment thereof set apart
for payment for all past dividend periods and the then current dividend period
and (ii) if such series of Preferred Shares does not have a cumulative
dividend, full dividends on the Preferred Shares of any series have been or
contemporaneously are declared and paid or declared and a sum sufficient for
the payment thereof set apart for payment for the then
 
                                      16
<PAGE>
 
current dividend period, no shares of any series of Preferred Shares shall be
redeemed (unless all outstanding Preferred Shares of such series are
simultaneously redeemed) or directly or indirectly purchased or acquired
(except by conversion into or exchange for capital shares of CRIIMI MAE
ranking junior to the Preferred Shares of such series as to dividends and upon
liquidation); provided, however, that the foregoing shall not prevent the
purchase or acquisition of Preferred Shares of such series to preserve the
REIT status of CRIIMI MAE or pursuant to a purchase or exchange offer made on
comparable terms to holders of all outstanding Preferred Shares of such
series.
 
  If fewer than all of the outstanding Preferred Shares of any series are to
be redeemed, the number of shares to be redeemed will be determined by the
Board and such shares may be redeemed pro rata from the holders of record of
such shares in proportion to the number of such shares held by such holders
(with adjustments to avoid redemption of fractional shares) or any other
equitable method determined by the Board.
 
  Notice of redemption will be mailed at least 30 days but not more than 60
days before the redemption date to each holder of record of Preferred Shares
of any series to be redeemed at the address shown on the share transfer books
of CRIIMI MAE. Each notice shall state: (i) the redemption date; (ii) the
number of shares and series of the Preferred Shares to be redeemed; (iii) the
redemption price; (iv) the place or places where certificates for such
Preferred Shares are to be surrendered for payment of the redemption price;
(v) that dividends on the shares to be redeemed will cease to accrue on such
redemption date; and (vi) the date upon which the holder's conversion rights,
if any, as to such shares shall terminate. If fewer than all the Preferred
Shares of any series are to be redeemed, the notice mailed to each such holder
thereof shall also specify the number of Preferred Shares to be redeemed from
each such holder. If notice of redemption of any Preferred Shares has been
given and if the funds necessary for such redemption have been set aside by
CRIIMI MAE in trust for the benefit of the holders of any Preferred Shares so
called for redemption, then from and after the redemption date dividends will
cease to accrue on such Preferred Shares, such Preferred Shares shall no
longer be deemed outstanding and all rights of the holders of such shares will
terminate, except the right to receive the redemption price. Any moneys so
deposited which remain unclaimed by the holders of the Preferred Shares at the
end of two years after the redemption date will be returned by such bank or
trust company to CRIIMI MAE.
 
  Liquidation Preference. Upon any voluntary or involuntary liquidation,
dissolution or winding up of the affairs of CRIIMI MAE, then, before any
distribution or payment shall be made to the holders of any Common Shares or
any other class or series of capital shares of CRIIMI MAE ranking junior to
the Preferred Shares in the distribution of assets upon any liquidation,
dissolution or winding up of CRIIMI MAE, the holders of each series of
Preferred Shares shall be entitled to receive out of assets of CRIIMI MAE
legally available for distribution to stockholders, liquidating distributions
in the amount of the liquidation preference per share (set forth in the
applicable Prospectus Supplement), plus an amount equal to all dividends
accrued and unpaid thereon (which shall not include any accumulation in
respect of unpaid dividends for prior dividend periods if such Preferred
Shares do not have a cumulative dividend). After payment of the full amount of
the liquidating distributions to which they are entitled, the holders of
Preferred Shares will have no right or claim to any of the remaining assets of
CRIIMI MAE. In the event that, upon any such voluntary or involuntary
liquidation, dissolution or winding up, the available assets of CRIIMI MAE are
insufficient to pay the amount of the liquidating distributions on all
outstanding Preferred Shares and the corresponding amounts payable on all
shares of other classes or series of capital shares of CRIIMI MAE ranking on a
parity with the Preferred Shares in the distribution of assets upon
liquidation, dissolution or winding up, then the holders of the Preferred
Shares and all other such classes or series of capital shares shall share
ratably in any such distribution of assets in proportion to the full
liquidating distributions to which they would otherwise be respectively
entitled.
 
  If liquidating distributions shall have been made in full to all holders of
Preferred Shares, the remaining assets of CRIIMI MAE shall be distributed
among the holders of any other classes or series of capital shares ranking
junior to the Preferred Shares upon liquidation, dissolution or winding up,
according to their respective rights and preferences and in each case
according to their respective number of shares. For such purposes, the
consolidation or merger of CRIIMI MAE with or into any other corporation,
trust or entity, or the sale, lease or
 
                                      17
<PAGE>
 
conveyance of all or substantially all of the property or business of CRIIMI
MAE, shall not be deemed to constitute a liquidation, dissolution or winding
up of CRIIMI MAE.
 
  Voting Rights. Holders of the Preferred Shares will not have any voting
rights, except as set forth below or as otherwise from time to time required
by law or as indicated in the applicable Prospectus Supplement.
 
  Unless provided otherwise for any series of Preferred Shares, so long as any
Preferred Shares remain outstanding, CRIIMI MAE will not, without the
affirmative vote or consent of the holders of at least a majority of the
shares of each series of Preferred Shares outstanding at the time, given in
person or by proxy, either in writing or at a meeting (such series voting
separately as a class), (i) authorize or create, or increase the authorized or
issued amount of, any class or series of capital shares ranking prior to such
series of Preferred Shares with respect to payment of dividends or the
distribution of assets upon liquidation, dissolution or winding up or
reclassify any authorized capital shares of CRIIMI MAE into any such shares,
or create, authorize or issue any obligation or security convertible into or
evidencing the right to purchase any such shares; or (ii) amend, alter or
repeal the provisions of CRIIMI MAE's Articles of Incorporation or the
Articles Supplementary for such series of Preferred Shares, whether by merger,
consolidation or otherwise (each, an "Event"), so as to materially and
adversely affect any right, preference, privilege or voting power of such
series of Preferred Shares or the holders thereof; provided, however, with
respect to the occurrence of any of the Events set forth in (ii) above, so
long as the Preferred Shares remain outstanding with the terms thereof
materially unchanged, taking into account that upon the occurrence of an
Event, CRIIMI MAE may not be the surviving entity, the occurrence of any such
Event shall not be deemed to materially and adversely affect such rights,
preferences, privileges or voting power of holders of Preferred Shares, and
provided further that (x) any increase in the amount of the authorized Common
Shares or Preferred Shares or the authorization, creation or issuance of any
other series of Preferred Shares or any other class or series of capital
shares, or (y) any increase in the amount of authorized shares of such series
or any other series of Preferred Shares or any other class or series of
capital shares, in each case ranking on a parity with or junior to the
Preferred Shares of such series with respect to payment of dividends or the
distribution of assets upon liquidation, dissolution or winding up, shall not
be deemed to materially and adversely affect such rights, preferences,
privileges or voting powers.
 
  The foregoing voting provisions will not apply if, at or prior to the time
when the act with respect to which such vote would otherwise be required shall
be effected, all outstanding shares of such series of Preferred Shares shall
have been redeemed or called for redemption and sufficient funds shall have
been deposited in trust to effect such redemption.
 
  Conversion Rights. The terms and conditions, if any, upon which any series
of Preferred Shares are convertible into Common Shares will be set forth in
the applicable Prospectus Supplement relating thereto. Such terms will include
the number of Common Shares into which the Preferred Shares are convertible,
the conversion price (or manner of calculation thereof), the conversion
period, provisions as to whether conversion will be at the option of the
holders of the Preferred Shares or CRIIMI MAE, the events requiring an
adjustment of the conversion price and provisions affecting conversion in the
event of the redemption of such Preferred Shares.
 
  Restrictions on Ownership and Transfer. As discussed below under "--Common
Shares--Restrictions on Ownership and Transfer," for CRIIMI MAE to qualify as
a REIT under the Internal Revenue Code of 1986, as amended (the "Code"), not
more than 50% in value of its outstanding capital shares may be owned,
directly or constructively, by five or fewer individuals (as defined in the
Code to include certain entities) during the last half of a taxable year. To
assist CRIIMI MAE in meeting this requirement, CRIIMI MAE may take certain
actions to limit the beneficial ownership, directly or indirectly, by a single
person of more than 9.8% of CRIIMI MAE's outstanding capital stock, including
any Preferred Shares of CRIIMI MAE. Therefore, the Articles Supplementary for
each series of Preferred Shares may contain certain provisions restricting the
ownership and transfer of the Preferred Shares. The applicable Prospectus
Supplement will specify any additional ownership limitation relating to a
series of Preferred Shares.

COMMON SHARES
 
  The following description of the Common Shares is summarized from relevant
portions of CRIIMI MAE's Articles of Incorporation and Bylaws, as amended. A
more complete description of the Common Shares may be obtained by reference to
such documents and to the documents incorporated by reference in this
Prospectus. The following statements are qualified in their entirety by such
reference.
 
  General. Stockholders are entitled to one vote for each Common Share held on
all matters presented for a vote to stockholders. The Board serves in
staggered three-year terms. Directors may be removed only for cause, upon the
affirmative vote of holders of a majority of the Common Shares voting together
as a single class. Except as otherwise provided in the Articles of
Incorporation, in meetings where a quorum is present, a majority of the votes
cast by stockholders is required to adopt a provision. Stockholders are
entitled to receive all assets available for distribution to the stockholders,
subject to any preferential rights of the holders of any Preferred Shares. The
Common Shares, when issued, will be fully paid and nonassessable and will not
be subject to redemption, except as provided in the Articles of Incorporation,
nor will they have any preference, conversion, exchange, preemptive or
cumulative voting rights.
 
  The transfer agent and register for the Common Shares is Registrar and
Transfer Company.
 
  Restrictions on Ownership and Transfer. The Code provides that a corporation
may not qualify as a REIT if more than 50% in value of the shares of the
corporation are owned, directly or indirectly, by five or fewer individuals,
which for this purpose includes pension funds and certain other tax-exempt
entities. Provisions of the Articles of Incorporation, intended to prevent
concentrated ownership of the capital stock of CRIIMI MAE that might
jeopardize its qualification as a REIT, authorize the Board to refuse to
effect a transfer of shares of capital stock of CRIIMI MAE to any person who
as a result would own in excess of 9.8% of the outstanding shares of capital
stock of CRIIMI MAE ("Excess Shares") and to redeem such Excess Shares.
 
                            DESCRIPTION OF WARRANTS
 
  CRIIMI MAE may issue Warrants for the purchase of Preferred Shares or Common
Shares. Warrants may be issued independently or together with any Debt
Securities, Preferred Shares or Common Shares, offered by any Prospectus
Supplement and may be attached to or separate from such Debt Securities,
Preferred Shares or Common Shares. Each series of Warrants will be issued
under a separate warrant agreement (a "Warrant Agreement") to be entered into
between CRIIMI MAE and a bank or trust company, as warrant agent (the "Warrant
Agent"), all as set forth in the Prospectus Supplement relating to the
particular issue of Warrants. The Warrant Agent will act solely as an agent of
CRIIMI MAE in connection with the Warrants and will not assume any obligation
or relationship of agency or trust for or with any holders of Warrants or
beneficial owners of Warrants. If Warrants are to be issued, a copy of the
form of Warrant Agreement will be filed by CRIIMI MAE as an exhibit to a
current report on Form 8-K and incorporated herein by reference. The following
summary of certain provisions of the form of Warrant Agreement does not
purport to be complete and is subject to, and is qualified in its entirety by
reference to, all the provisions of the applicable Warrant Agreement.
 
  General. If Warrants are offered, the related Prospectus Supplement will
describe the Warrant Agreement and the terms of the Warrants, including the
following: (i) the title of such Warrants; (ii) the aggregate number of such
Warrants; (iii) the price or prices at which such Warrants will be issued;
(iv) the currencies in which the price or prices of such Warrants may be
payable; (v) the designation, amount and terms of the Preferred Shares and/or
Common Shares purchasable upon exercise of such Warrants; (vi) the designation
and terms of the Debt Securities, Preferred Shares and/or Common Shares, if
any, with which such Warrants are issued and the number of such Warrants
issued with each such Security; (vii) if applicable, the date on and after
which such Warrants and the Preferred Shares and/or Common Shares purchasable
upon exercise of such Warrants will be separately transferable; (viii) the
price or prices at which and the currency or currencies in which the Preferred
Shares and/or Common Shares purchasable upon exercise of such Warrants may be
purchased; (ix) the date on which the right to exercise such Warrants shall
commence and the date on which such right shall expire; (x) the minimum and
 
                                      19
<PAGE>
 
maximum amount of such Warrants which may be exercised at any one time; (xi)
information with respect to book-entry procedures, if any; (xii) a discussion
of certain United States federal income tax considerations; and (xiii) any
other material terms of such Warrants, including terms, procedures and
limitations relating to exchange or exercise of such Warrants.
 
  Exercise. Prior to the exercise of any Warrants to purchase Preferred Shares
and/or Common Shares, holders of such Warrants will not have any of the rights
of holders of Preferred Shares or Common Shares, as the case may be,
purchasable upon such exercise, including the right to receive payments of
dividends, if any, on the Preferred Shares or Common Shares purchasable upon
such exercise, or to exercise any applicable right to vote.
 
  Each Warrant will entitle the holder to purchase Preferred Shares and/or
Common Shares at such exercise price as shall in each case be set forth in, or
calculable from, the Prospectus Supplement relating to the Warrants. Warrants
may be exercised at any time up to 5:00 P.M. New York time on the expiration
date set forth in the Prospectus Supplement relating to such Warrants. After
the close of business on the expiration date (or such later date to which such
expiration date may be extended by CRIIMI MAE), unexercised Warrants will
become void.
 
  Restrictions on Ownership and Transfer. As discussed above under "--Common
Shares--Restrictions on Ownership and Transfer," for CRIIMI MAE to qualify as
a REIT under the Code, not more than 50% in value of its outstanding capital
shares may be owned, directly or constructively, by five or fewer individuals
(as defined in the Code to include certain entities) during the last half of a
taxable year. To assist CRIIMI MAE in meeting this requirement, CRIIMI MAE may
take certain actions to limit the beneficial ownership, directly or
indirectly, by a single person of more than 9.8% of CRIIMI MAE's outstanding
capital stock. An individual or entity that owns Warrants to acquire Common
Shares and/or Preferred Shares will be deemed to own such Common Shares or
Preferred Shares for purposes of meeting the ownership requirement. Therefore,
the terms of any Warrant Agreement entered into in connection with the
issuance of Warrants may contain certain provisions restricting the ownership
and transfer of the Warrants. The applicable Prospectus Supplement will
specify any additional ownership limitation relating to the Warrants.
 
            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
  The following summary of certain United States federal income tax
considerations to CRIIMI MAE is based on current law, is for general
information only, and is not tax advice. The tax treatment of a holder of any
of the Securities will vary depending upon the terms of the specific
Securities acquired by such holder, as well as such holder's particular
situation, and this discussion does not attempt to address any aspects of
United States federal income taxation relating to holders of Securities.
Certain United States federal income tax considerations relevant to holders of
the Securities will be provided in the applicable Prospectus Supplement
relating thereto.
 
  This discussion does not consider specific facts and circumstances that may
be relevant to a particular holder's tax position, and does not consider U.S.
state and local or non-U.S. tax consequences. Furthermore, the following
discussion is based on provisions of the Code and administrative and judicial
interpretations, all of which are subject to change, possibly on a retroactive
basis.
 
  EACH INVESTOR IS ADVISED TO CONSULT THE APPLICABLE PROSPECTUS SUPPLEMENT, AS
WELL AS HIS OWN TAX ADVISOR, REGARDING THE TAX CONSEQUENCES TO HIM OF THE
ACQUISITION, OWNERSHIP AND SALE OF THE SECURITIES, INCLUDING THE FEDERAL,
STATE, LOCAL, FOREIGN AND OTHER TAX CONSEQUENCES OF SUCH ACQUISITION,
OWNERSHIP AND SALE AND OF POTENTIAL CHANGES IN APPLICABLE TAX LAWS.
 
  CRIIMI MAE has qualified, and intends to continue to qualify, as a REIT
under the Code. Qualification for treatment as a REIT requires CRIIMI MAE to
meet certain criteria including certain requirements regarding the
 
                                      20
<PAGE>
 
nature of its ownership, assets, income and distributions of taxable income. A
REIT generally is not subject to federal income tax on that portion of its
ordinary income or capital gains that is distributed currently to
stockholders. CRIIMI MAE has distributed and intends to continue to distribute
substantially all of its taxable income to stockholders and to meet
distribution requirements to continue to qualify as a REIT. CRIIMI MAE will
generally be subject to federal income tax at normal corporate rates on its
undistributed income and to a 4% excise tax under the Code on the amount, if
any, by which 85% of its REIT taxable income (including accrued but unpaid
interest income) and 95% of any net capital gain exceed the amount actually
distributed to its stockholders during the year (or declared as a dividend
during October, November or December of a calendar year, if distributed during
the following January as ordinary income dividends). Accrued income for the
last month of each quarter is generally received within 30 days after the end
of the quarter. CRIIMI MAE is not aware of any present circumstances that
would cause it to fail to qualify as a REIT, nor does it anticipate any such
circumstances in the reasonably foreseeable future. If the U.S. Internal
Revenue Service ("IRS") successfully challenged the tax status of CRIIMI MAE
as a REIT, CRIIMI MAE's earnings would become subject to federal income tax
(including any applicable minimum tax) at corporate rates.
 
  To assist in maintaining CRIIMI MAE's qualification as a REIT under the
Code, CRIIMI MAE's Articles of Incorporation provide that no person or persons
acting as a group (defined to include partnerships, corporations, trusts and
other entities), with the exception of C.R.I., Inc. or its affiliates, shall
at any time directly or indirectly acquire ownership of more than 9.8% of the
outstanding shares of CRIIMI MAE's capital stock.
 
                             PLAN OF DISTRIBUTION
 
  CRIIMI MAE may sell Securities to or through one or more underwriters, and
also may sell Securities directly to other purchasers or through agents. 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, at market
prices prevailing at the time of sale, at prices related to such prevailing
market prices or at negotiated prices. If underwriters are used in the sale of
Securities, the Securities will be acquired by the underwriters for their own
account and may be resold from time to time in one or more transactions,
including negotiated transactions. If the Securities are sold through one or
more agents, as designated by CRIIMI MAE from time to time, any such agent
will be acting on a best efforts basis for the period of its appointment.
 
  In connection with the sale of Securities, underwriters may receive
compensation from CRIIMI MAE or from purchasers of Securities, for whom they
may 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 (which may be all or a portion of the discount to be
received by such underwriter from CRIIMI MAE) 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 they receive from CRIIMI MAE,
and any profit on the resale of Securities they realize may be deemed to be
underwriting discounts and commissions, under the Securities Act. Any such
underwriter or agent will be identified, and any such compensation received
from CRIIMI MAE will be described, in the Prospectus Supplement.
 
  Unless otherwise specified in the related Prospectus Supplement, each series
of Securities will be a new issue with no established trading market, other
than the Common Shares which are listed on the NYSE. Any Common Shares sold
pursuant to a Prospectus Supplement are expected to be listed on such
exchange, subject to official notice of issuance. CRIIMI MAE may elect to list
any series of Debt Securities, Preferred Shares or Warrants on a securities
exchange, but is not obligated to do so. It is possible that one or more
underwriters may make a market in a series of Securities, but will not be
obligated to do so and may discontinue any market making at any time without
notice. Therefore, no assurance can be given as to the liquidity of the
trading market for any Securities (other than Common Shares).
 
 
                                      21
<PAGE>
 
  Under agreements CRIIMI MAE may enter into, underwriters, dealers, and
agents who participate in the distribution of Securities may be entitled to
indemnification by CRIIMI MAE against certain liabilities, including
liabilities under the Securities Act.
 
  Underwriters, dealers and agents may engage in transactions with, or perform
services for, or be customers of, CRIIMI MAE in the ordinary course of
business. In connection with any particular issue of Debt Securities, CRIIMI
MAE may enter into hedging transactions with an underwriter, dealer or agent
participating in such transaction or an affiliate thereof.
 
  If so indicated in the Prospectus Supplement, CRIIMI MAE will authorize
underwriters or other persons acting as CRIIMI MAE's agents to solicit offers
by certain institutions to purchase Securities from CRIIMI MAE 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 CRIIMI MAE. 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 MATTERS
 
  Certain matters relating to the validity of the Securities will be passed
upon for CRIIMI MAE by Swidler & Berlin, Chartered, Washington, D.C.
 
                                    EXPERTS
 
  The financial statements included in CRIIMI MAE's Annual Report on Form 10-K
incorporated herein by reference, have been audited by Arthur Andersen LLP,
independent public accountants, as indicated in their reports with respect
thereto, and have been incorporated by reference herein in reliance upon the
authority of said firm as experts in accounting and auditing in giving said
reports.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Under Maryland law, a corporation formed under Maryland law is permitted to
limit, by provisions in its articles of incorporation, the liability of its
directors and officers to the corporation or its stockholders for money
damages except for (i) actual receipt of an improper benefit or profit in
money, property or services or (ii) active and deliberate dishonesty
established by a final judgment as being material to the cause of action.
CRIIMI MAE's Articles of Incorporation include such a provision which limits
such liability to the fullest extent permitted by Maryland law.
 
  CRIIMI MAE's Amended and Restated Bylaws provide that CRIIMI MAE shall
indemnify its directors, officers and advisers, and may indemnify other
persons who may be indemnified, to the fullest extent permitted by Maryland
law against any liability and related expenses (including attorneys' fees)
incurred in conjunction with any proceeding or threatened proceeding in which
any of them may be involved, or threatened to be involved, as a party or
otherwise, arising out of or incidental to CRIIMI MAE's business. CRIIMI MAE
has purchased and maintains liability insurance against liabilities that may
be asserted against such persons in connection with CRIIMI MAE, whether or not
indemnification against such liabilities would be permitted under the
provisions of CRIIMI MAE's Articles of Incorporation.
 
  Section 2-418 of the General Corporation Law of the State of Maryland
provides, together with the Amended and Restated Bylaws described above, for
the indemnification of directors, officers and other corporate agents in terms
sufficiently broad to indemnify such persons, under certain circumstances, for
liabilities (including reimbursements of expenses incurred) arising under the
Securities Act.

ITEM 17. UNDERTAKINGS
 
  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 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; and (2)
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.
 
  The undersigned registrant also 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 Section 15(d) of
 
                                     II-2
<PAGE>
 
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.
 
  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 provisions described in Item 15, 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
Securities Act of 1933 and is, therefore, unenforceable. If 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 director, officer or controlling person in
connection with the Securities being registered, the registrant will, unless
in the opinion of its counsel the matter has 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
Securities Act of 1933 and will be governed by the final adjudication of such
issue.
 
  The undersigned registrant hereby undertakes to file an application for the
purpose of determining the eligibility of the Trustee to act under subsection
(a) of section 310 of the Trust Indenture Act (the "TIA") in accordance with
the rules and regulations prescribed by the Commission under section 305(b)(2)
of the TIA.
 
  The undersigned registrant hereby further undertakes that: (1) For purposes
of determining any liability under the Securities Act of 1933, the information
omitted from the form of prospectus filed as part of this Registration
Statement in reliance upon Rule 430A and contained in a form of prospectus
filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the
Securities Act shall be deemed to be part of this Registration Statement as of
the time it was declared effective; and (2) For the purpose of determining any
liability under the Securities Act, each post-effective amendment that
contains a form of prospectus 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.

provided, however, that in determining whether the Holders of the requisite
principal amount of the Outstanding Securities have given any request, demand,

a meeting of Holders for quorum purposes, and for the purpose of making the
calculations required by TIA Section 313, (i) the principal amount of an
Original Issue Discount Security that may be counted in making such

shall be protected in making such determination or calculation or in relying
upon any such request, demand, authorization, direction, notice, consent or
waiver, only Securities which a Responsible Officer of the Trustee knows to be
so owned shall be so disregarded. Securities so owned which have been pledged in
good faith may be regarded as Outstanding if the pledgee establishes to the

corresponds to such maturity, yields for the two published maturities most
closely corresponding to such maturity shall be calculated pursuant to the
immediately preceding sentence and the Reinvestment Rate shall be interpolated
or extrapolated from such yields on a straight-line basis, rounding in each of
such relevant periods to the nearest month.  For the purposes of calculating the
Reinvestment Rate, the most recent Statistical Release published prior to the
date of determination of the Make-Whole Amount shall be used.  If the format or
content of the Statistical Release changes in a manner that precludes
determination of the Treasury yield in the above manner, then the Treasury yield
shall be determined in the manner that most closely approximates the above
manner, as reasonably determined by the Issuer.  If the format or content of the
Statistical Release changes in a manner that precludes determination of the
Treasury Yield in the above manner, then the Treasury Yield shall be determined

          SECTION 103. FORM OF DOCUMENTS DELIVERED TO TRUSTEE. In any case where
several matters are required to be certified by, or covered by an opinion of,
any specified Person, it is not necessary that all such matters be certified by,

opinion as to some matters and one or more other such Persons as to other
matters, and any such Person may certify or give an opinion as to such matters

certificate or representations of or by counsel, unless such officer knows, or
in the exercise of reasonable care should know, that the opinion, certificate or
representations with respect to the matters upon which his certificate or
opinion is based are erroneous.  Any such Opinion of Counsel or certificate or
representations may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, an officer or officers of the

possession of the Issuer, unless such counsel knows that the certificate or
opinion or representations as to such matters are erroneous.

          Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

          SECTION 104. ACTS OF HOLDERS. (a) Any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person or
by agents duly appointed in writing. If, but only if, Securities of a series are
issuable as Bearer Securities, any request, demand, authorization, direction,
notice, consent, waiver or other action provided by this Indenture to be given
or taken by Holders of Securities of such series may, alternatively, be embodied
in and evidenced by the record of Holders of Securities of such series voting in
favor thereof, either in person or by proxies duly appointed in writing, at any
meeting of Holders of Securities of such series duly called and held in
accordance with the provisions of Article Fifteen, or a combination of such
instruments and any such record. Except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments or record
or both are delivered to the Trustee and, where it is hereby expressly required,
to the Issuer. Such instrument or instruments and any such record (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders signing such instrument or instruments or so voting
at any such meeting. Proof of execution of any such instrument or of a writing
appointing any such agent, or of the holding by any Person of a Security, shall
be sufficient for any purpose of this Indenture and (subject to Section 315 of
the TIA) conclusive in favor of the Trustee and the Issuer and any agent of the
Trustee or the Issuer, if made in the manner provided in this Section. The
record of any meeting of Holders of Securities shall be proved in the manner
provided in Section 1506.

          (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems sufficient and in accordance with such reasonable rules as the Trustee may
determine; and the Trustee may in any instance require further proof with
respect to any of the matters referred to in this Section.

                                     - 10 -

          (c) The ownership, principal amount and serial numbers of Registered
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, shall be proved by the Security Register.

          (d) The ownership, principal amount and serial numbers of Bearer
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same may be proved by the production of such
Bearer Securities or by a certificate executed, as, depositary, by any trust
company, bank, banker or other depositary reasonably acceptable to the Issuer,
wherever situated, if such certificate shall be deemed by the Issuer and the
Trustee to be satisfactory, showing that at the date therein mentioned such
Person had on deposit with such depositary, or exhibited to it, the Bearer
Securities therein described; or such facts may be proved by the certificate or
affidavit of the Person holding such Bearer Securities, if such certificate or
affidavit is deemed by the Trustee to be satisfactory.  The Trustee and the
Issuer may assume that such ownership of any Bearer Security continues until (1)
another certificate or affidavit bearing a later date issued in respect of the
same Bearer Security is produced, or (2) such Bearer Security is produced to the
Trustee by some other Person, or (3) such Bearer Security is surrendered in
exchange for a Registered Security, or (4) such Bearer Security is no longer
Outstanding.  The ownership, principal amount and serial numbers of Bearer
Securities held by the Person so executing such instrument in writing and the
date of the commencement and the date of the termination of holding the same may
also be proved in any other manner which the Trustee deems sufficient.

          (e) If the Issuer shall solicit from the Holders of any Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Issuer may, at its option, in or pursuant to a Board
Resolution, fix in advance a record date for the determination of Holders of
Registered Securities entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other Act, but the Issuer shall have no
obligation to do so.  If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of Registered Securities
of record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Securities have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Outstanding Securities shall be computed as of
such record date, provided that no such authorization, agreement or consent by
the Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the  provisions of this Indenture not later than eleven
months after the record date.

          (f) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee, any
Security Registrar, any Paying Agent, any Authenticating Agent or the Issuer in
reliance thereon, whether or not notation of such action is made upon such
Security.

          SECTION 105.  NOTICES, ETC., TO TRUSTEE AND ISSUER .  Any request,
demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with

     (A)  the Trustee by a Holder or by the Issuer shall be sufficient for every
          purpose hereunder if made, given, furnished or filed in writing to or
          with the Trustee at its Corporate Trust Office, or

     (B)  the Issuer by the Trustee or by any Holder shall be sufficient for
          every purpose hereunder (unless otherwise herein expressly provided)
          if in writing and mailed, first class postage prepaid, to the Issuer
          addressed to it at the address of its principal

                                     - 11 -
<PAGE>
 
          office specified in the first paragraph of this Indenture or at any
          other address previously furnished in writing to the Trustee by the
          Issuer.

          SECTION 106. NOTICE TO HOLDERS; WAIVER. Where this Indenture provides
for notice of any event to Holders of Registered Securities by the Issuer or the
Trustee, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each such Holder affected by such event, at his address as it appears in the
Security Register, not later than the latest date, and not earlier than the
earliest date, prescribed for the giving of such notice. In any case where
notice to Holders of Registered Securities is given by mail, neither the failure
to mail such notice, nor any defect in any notice so mailed, to any particular
Holder shall affect the sufficiency of such notice with respect to other Holders
of Registered Securities or the sufficiency of any notice to Holders of Bearer
Securities given as provided herein. Any notice mailed to a Holder in the manner
herein prescribed shall be conclusively deemed to have been received by such
Holder, whether or not such Holder actually receives such notice.

          If by reason of the suspension of or irregularities in regular mail
service or by reason of any other cause it shall be impracticable to give such
notice by mail, then such notification to Holders of Registered Securities as
shall be made with the approval of the Trustee shall constitute a sufficient
notification to such Holders for every purpose hereunder.

          Except as otherwise expressly provided herein or otherwise specified
with respect to any Securities pursuant to Section 301, where this Indenture
provides for notice to Holders of Bearer Securities of any event, such notice
shall be sufficiently given if published in an Authorized Newspaper in New York
City and in such other city or cities as may be specified in such Securities on
a Business Day, such publication to be not later than the latest date, and not
earlier than the earliest date, prescribed for the giving of such notice.  Any
such notice shall be deemed to have been given on the date of such publication
or, if published more than once, on the date of the first such publication.

          If by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder.  Neither the failure to give notice by
publication to any particular Holder of Bearer Securities as provided above, nor
any defect in any notice so published, shall affect the sufficiency of such
notice with respect to other Holders of Bearer Securities or the sufficiency of
any notice to Holders of Registered Securities given as provided herein.

          Any request, demand, authorization, direction, notice, consent, waiver
or Act required or permitted under this Indenture shall be in the English
language, except that, if the Issuer so elects, any published notice may be in
an official language of the country of publication.

          Where this Indenture provides for notice in any manner, such notice
may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such

          SECTION 109. SEVERABILITY CLAUSE. In case any provision in this
Indenture or in any Security or coupon shall be deemed invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

          SECTION 110. BENEFITS OF INDENTURE. Nothing in this Indenture or in
the Securities or coupons, express or implied, shall give to any Person, other
than the parties hereto, any Security Registrar, any Paying Agent, any
Authenticating Agent and their successors hereunder and the Holders any benefit
or any legal or equitable right, remedy or claim under this Indenture.

          SECTION 111. GOVERNING LAW. This Indenture and the Securities and
coupons shall be governed by and construed in accordance with the laws of the
State of [Delaware].

          SECTION 112. LEGAL HOLIDAYS. In any case where any Interest Payment
Date, Redemption Date, Repayment Date, sinking fund payment date, Stated
Maturity or Maturity of any Security, or the last date on which a Holder has the
right to exchange Securities of a series that are exchangeable, shall be a Legal
Holiday at any Place of Payment, then (notwithstanding any other provision of
this Indenture or any Security or coupon other than a provision in any Security
or coupon that specifically states that such provision shall apply in lieu
hereof), payment of interest or any Additional Amounts or principal (and premium
or Make-Whole Amount, if any) need not be made at such Place of Payment on such
date and such Securities need not be exchanged on such date, but such payment
may be made and such Securities may be exchanged on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on the
Interest Payment Date, Redemption Date, Repayment Date or sinking fund payment
date, or at the Stated Maturity or Maturity or on such last day for exchange,
provided that no interest shall accrue on the amount so payable for the period
from and after such Interest Payment Date, Redemption Date, Repayment Date,
sinking fund payment date, Stated Maturity or Maturity or last day for or
exchange, as the case may be.

          SECTION 113. CONFLICT WITH TRUST INDENTURE ACT. This Indenture is

          SECTION 114. COUNTERPARTS. This Indenture may be executed in several
counterparts, each of which shall be an original and all of which shall
constitute but one and the same instrument.

          SECTION 115. JUDGMENT CURRENCY. The Issuer agrees, to the fullest
extent that it may effectively do so under applicable law, that (a) if for the
purpose of obtaining judgment in any court it is necessary to convert the sum
due in respect of the principal of, or premium or interest, if any, or
Additional Amounts on the Securities of any series (the "Required Currency")
into a currency in which a judgment will be rendered (the "Judgment Currency"),
the rate of exchange used shall be the rate at which in accordance with normal
banking procedures the Trustee could purchase in The City of New York the
Required Currency with the Judgment Currency on the New York Banking Day
preceding that on which a final unappealable judgment is given and (b) the
Issuer's obligations under this Indenture to make payments in the Required
Currency (i) shall not be discharged or satisfied by any tender, or any recovery
pursuant to any judgment (whether or not entered in accordance with clause (a)),
in any currency other than the Required Currency, except to the extent that such
tender or recovery shall result in the actual receipt, by the payee, of the full
amount of the Required Currency expressed to be payable in respect of such
payments, (ii) shall be enforceable as an alternative or additional cause of
action for the purpose of recovering in the Required Currency the amount, if
any, by which such actual receipt shall fall short of the full amount of the
Required Currency so expressed to be payable, and (iii) shall not be affected by
judgment being obtained for any other sum due under this Indenture. For purposes
of the foregoing, "New York Banking Day" means any day except a Legal Holiday in
The City of New York.

          SECTION 116. NONRECOURSE. Unless otherwise provided in the Board
Resolution authorizing a particular series of Securities in accordance with
Section 301, no recourse under or upon any obligation, covenant or agreement
contained in this Indenture, in any Security or coupon appertaining thereto, or
because of any Debt evidenced thereby (including, without limitation, any
obligation or indebtedness relating to the principal of, or premium or Make-
Whole Amount, if any, interest or any other amounts due, or claimed to be due,
on any Security issued hereunder), or for any claim based thereon or otherwise
in respect thereof, shall be had (i) against any Person which owns an interest,
directly or indirectly, in the Issuer, or (ii) against any promoter, as such, or
against any past, present or future shareholder, officer or trustee, as such, of
the Issuer or of any successor, either directly or through the Issuer or any
successor, under any rule of law, statute or constitutional provision or by the
enforcement of any assessment or by any legal or equitable proceeding or
otherwise, all such liability being expressly waived and released by the
acceptance of the Securities by the Holders thereof and as part of the
consideration for the issue of the Securities. Unless otherwise provided in the
Board Resolution authorizing a particular series of Securities in accordance
with Section 301, the Holders of the Securities hereunder acknowledge by the
acceptance of the Securities that their sole remedies under this Indenture for
any Default by the Issuer in the payment of the principal of, or any premium or
Make-Whole Amount, if any, interest or any amounts due, or claimed to be due, on
any Security, or otherwise, are limited to claims against the property of the
Issuer as provided in Section 503 hereof.

                                SECURITIES FORMS

          SECTION 201. FORMS OF SECURITIES. The Registered Securities, if any,
of each series and the Bearer Securities, if any, of each series and related
coupons shall be in substantially the forms as shall be established in one or
more indentures supplemental hereto or approved from time to time by or pursuant
to a Board Resolution in accordance with Section 301, shall have such
appropriate insertions, omissions, substitutions and other variations as are
required or permitted by this Indenture or any indenture supplemental hereto,
and may have such letters, numbers or other marks of identification or
designation and such legends or endorsements placed thereon as the Issuer may
deem appropriate and as are not inconsistent with the provisions of this
Indenture, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange on which the Securities may be listed, or to conform to usage.

          Unless otherwise specified as contemplated by Section 301, Bearer
Securities shall have interest coupons attached.

          The definitive Securities and coupons shall be printed, lithographed
or engraved or produced by any combination of these methods on a steel engraved
border or steel engraved borders or may be produced in any other manner, all as
determined by the officers executing such Securities or coupons, as evidenced by
their execution of such Securities or coupons.

          SECTION 202. FORM OF TRUSTEE'S CERTIFICATE OF AUTHENTICATION. Subject
to Section 611, the Trustee's certificate of authentication shall be in
substantially the following form:

                    This is one of the Securities of the series designated
          therein referred to in the within-mentioned Indenture.

                                    (TRUSTEE)
                                    as Trustee

                                    By:

          SECTION 203. SECURITIES ISSUABLE IN GLOBAL FORM. If Securities of or
within a series are issuable in global form, as specified as contemplated by
Section 301, then, notwithstanding clause (9) of Section 301 and the provisions
of Section 302, any such Security shall represent such of the Outstanding
Securities of such series as shall be specified therein and may provide that it
or any number of such Securities shall represent the aggregate amount of
Outstanding Securities of such series from time to time endorsed thereon and may
also provide that the aggregate amount of Outstanding Securities of such series
represented thereby may from time to time be increased or decreased to reflect
exchanges. Any endorsement of a Security in global form to reflect the amount,
or any increase or decrease in the amount, of Outstanding Securities represented
thereby shall be made in such manner and by such Person or Persons as shall be
specified therein or in the Issuer Order to be delivered pursuant to Section 303
or 304. Subject to the provisions of Section 303 and, if applicable, Section
304, the Trustee shall deliver and redeliver any Security in permanent global
form in the manner and upon instructions given by the Person or Persons
specified therein or in the applicable Issuer Order. If an Issuer Order pursuant
to Section 303 or 304 has been, or simultaneously is, delivered, any
instructions by the Issuer with respect to endorsement or delivery or redelivery
of a Security in global form shall be in writing but need not comply with
Section 102 and need not be accompanied by an Opinion of Counsel.

          The provisions of the last sentence of Section 303 shall apply to any
Security represented  by a Security in global form if such Security was never
issued and sold by the Issuer and the Issuer delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.

          Notwithstanding the provisions of Section 307, unless otherwise
specified as contemplated by Section 301, payment of principal of, and any
premium and interest on, and any Additional Amounts in respect of, any Security
in temporary or permanent global form shall be made to the Person or Persons
specified therein.

          Notwithstanding the provisions of Section 308 and except as provided
in the preceding  paragraph, the Issuer, the Trustee and any agent of the Issuer
and the Trustee shall treat as the Holder of such principal amount of
Outstanding Securities represented by a global Security (a) in the case of a
global Security in registered form, the Holder of such global Security in
registered form, or (b) in the case of a global Security in bearer form, the
Person or Persons specified pursuant to Section 301.

          All Securities of any one series and the coupons, if any, appertaining
to any Bearer Securities of the series shall be substantially identical except,
in the case of Registered Securities, as to denomination and except as may
otherwise be provided in or pursuant to the Board Resolution establishing the
series (subject to Section 303 and the second paragraph of this Section 301) and
set forth in an Officers' Certificate or in any indenture supplemental hereto.
All Securities of any one series need not be issued at the same time and, unless
otherwise provided, a series may be reopened, without the consent of the
Holders, for issuances of additional Securities of such series.

          If any of the terms of the Securities of any series are established by
action taken pursuant to one or more Board Resolutions, a copy of an appropriate
record of such action(s) shall be certified by the Secretary or an Assistant
Secretary of the Issuer and delivered to the Trustee at or prior to the delivery
of the Officers' Certificate setting forth the terms of the Securities of such
series.

          SECTION 302. CURRENCY, DENOMINATIONS. Unless otherwise provided as
contemplated by Section 301, the principal of, any premium and interest on and
any Additional Amounts with respect to the Securities shall be payable in
Dollars.  Unless otherwise provided as contemplated by Section 301, Registered
Securities denominated in Dollars (other than Registered Securities issued in
global form, which may be of any denomination) shall be issuable in
denominations of $1,000 and any integral multiple thereof, and the Bearer
Securities denominated in Dollars (other than Bearer Securities issued in global
form, which may be of any denomination) shall be issuable in denominations of
$5,000 and any integral multiple thereof.  Securities not denominated in Dollars
shall be issuable in such denominations as are established with respect to such
Securities in or pursuant to this Indenture.

          SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING. The
Securities and any coupons appertaining thereto shall be executed on behalf of
the Issuer by its Chairman of the Board, its President or one of its Vice
Presidents (whether or not designated by a number or word or words added before
or after the title "vice president"), under its corporate seal reproduced
thereon, and attested by its Secretary or one of its Assistant Secretaries.  The
signature of any of these officers on the Securities and coupons may be manual
or facsimile signatures of the present or any future such authorized officer and
may be imprinted or otherwise reproduced on the Securities.

          Securities or coupons bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Issuer shall bind
the Issuer, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities or coupons.

          At any time and from time to time after the execution and delivery of
this Indenture, the Issuer may deliver the Securities of any series, together
with any coupon appertaining thereto, executed by the Issuer to the Trustee for
authentication, together with an Issuer Order for the  authentication and
delivery of such Securities, and the Trustee in accordance with the Issuer Order
shall authenticate and deliver such Securities; provided, however, that, in
connection with its original issuance, no Bearer Security shall be mailed or
otherwise delivered to any location in the United States; and provided further
that, unless otherwise specified with respect to any series of Securities
pursuant to Section 301, a Bearer Security may be delivered in connection with
its original issuance only if the Person entitled to receive such Bearer
Security shall have furnished a certificate to Euroclear or CEDEL (with a copy
to the Trustee), as the case may be, in the form set forth in Exhibit A-1 to
this Indenture or such other certificate as may be specified with respect to any
series of Securities pursuant to Section 301, dated no earlier than 15 days
prior to the earlier of the date on which such Bearer Security is delivered and
the date on which any temporary Security first becomes exchangeable for such
Bearer Security in accordance with the terms of such temporary Security and this
Indenture.  If any Security shall be represented by a permanent global Bearer
Security, then, for purposes of this Section and Section 304, the notation of a
beneficial owner's interest therein upon original issuance of such Security or
upon exchange of a portion of a temporary global Security shall be deemed to be
delivery in connection with its original issuance of such beneficial owner's
interest in 

                                     - 19 -
<PAGE>
 
such permanent global Security. Except as permitted by Section 306, the Trustee
shall not authenticate and deliver any Bearer Security unless all appurtenant
coupons for interest then matured have been detached and canceled.

          If all the Securities of any series are not to be issued at one time
and if the Board Resolution or supplemental indenture establishing such series
shall so permit, such Issuer Order may set forth procedures acceptable to the
Trustee for the issuance of such Securities and determining the terms of
particular Securities of such series, such as interest rate or formula, maturity
date, date of issuance and date from which interest shall accrue.  In
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to TIA Section 315(a) through 315(d)) shall be
fully protected in relying upon:

          (a)  an Opinion of Counsel stating that:

               (1) the terms and the form or forms of such Securities and any
               coupons have been established in conformity with the provisions
               of this Indenture; and

               (2) such Securities, together with any coupons appertaining
               thereto, when completed by appropriate insertions and executed
               and delivered by the Issuer to the Trustee for authentication in
               accordance with this Indenture, authenticated and delivered by
               the Trustee in accordance with this Indenture and issued by the
               Issuer in the manner and subject to any conditions specified in
               such Opinion of Counsel, will constitute legal, valid and binding
               obligations of the Issuer, enforceable in accordance with their
               terms, subject to applicable bankruptcy, insolvency,
               reorganization and other similar laws of general applicability
               relating to or affecting the enforcement of creditors' rights
               generally and to general equitable principles and will entitle
               the Holders thereof to the benefits of this Indenture; and

          (b)  an Officers' Certificate stating that all conditions precedent
    provided for in this Indenture relating to the issuance of the Securities
    have been complied with and that, to the best of the knowledge of the
    signers of such certificate, no Event of Default with respect to any of the
    Securities shall have occurred and be continuing.

          If such form or terms have been so established, the Trustee shall not
be required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties,
obligations or immunities under the Securities and this Indenture or otherwise
in a manner which is not reasonably acceptable to the Trustee.

          Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Officers' Certificate otherwise required
pursuant to Section 301 or an Issuer Order, or an Opinion of Counsel or an
Officers' Certificate otherwise required pursuant to the preceding paragraph at
the time of issuance of each Security of such series, but such order, opinion
and certificates, with appropriate modifications to cover such future issuances,
shall be delivered at or before the time of issuance of the first Security of
such series.

          Each Registered Security shall be dated the date of its authentication
and each Bearer Security shall be dated as of the date specified as contemplated
by Section 301.

                                     - 20 -

          No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security or Security to which such coupon appertains a certificate of
authentication substantially in the form provided for herein duly executed by
the Trustee by manual signature of an authorized signatory, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder and is entitled to
the benefits of this Indenture.  Notwithstanding the foregoing, if any Security
shall have been authenticated and delivered hereunder but never issued and sold
by the Issuer, and the Issuer shall deliver such Security to the Trustee for
cancellation as provided in Section 309 together with a written statement (which
need not comply with Section 102 and need not be accompanied by an Opinion of
Counsel) stating that such Security has never been issued and sold by the
Issuer, for all purposes of this Indenture such Security shall be deemed never
to have been authenticated and delivered hereunder and shall never be entitled
to the benefits of this Indenture.

          SECTION 304. TEMPORARY SECURITIES. (a) Pending the preparation of
definitive Securities of any series, the Issuer may execute, and upon Issuer
Order the Trustee shall authenticate and deliver, temporary Securities which are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any
authorized denomination, substantially of the tenor of the definitive Securities
in lieu of which they are issued, in registered form, or, if authorized, in
bearer form with one or more coupons or without coupons, and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities may determine, as conclusively evidenced by
their execution of such Securities.  Such temporary Securities may be in global
form.

          Except in the case of temporary Securities in global form (which shall
be exchanged in accordance with Section 304(b) or as otherwise provided in or
pursuant to a Board Resolution), if temporary Securities of any series are
issued, the Issuer will cause definitive Securities of that series to be
prepared without unreasonable delay.  After the preparation of definitive
Securities of such series, the temporary Securities of such series shall be
exchangeable for definitive Securities of such series upon surrender of the
temporary Securities of such series at the office or agency of the Issuer in a
Place of Payment for that series, without charge to the Holder.  Upon surrender
for cancellation of any one or more temporary Securities of any series
(accompanied by any nonmatured coupons appertaining thereto), the Issuer shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
like principal amount of definitive Securities of the same series of authorized
denominations; provided, however, that no definitive Bearer Security shall be
delivered in exchange for a temporary Registered Security, and provided further
that a definitive Bearer Security shall be delivered in exchange for a temporary
Bearer Security only in compliance with the conditions set forth in this
Indenture. Until so exchanged, the temporary Securities of any series shall in
all respects be entitled to the same benefits under this Indenture as definitive
Securities of such series.

          (b) Unless otherwise provided in or pursuant to a Board Resolution,
this Section 304(b) shall govern the exchange of temporary Securities issued in
global form other than through the facilities of The Depository Trust Company
("DTC").  If any such temporary Security is issued in global form, then such
temporary global Security shall, unless otherwise provided therein, be delivered
to the London office of a depositary or common depositary (the "Common
Depositary"), for the benefit of Euroclear and CEDEL, for credit to the
respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).

          Without unnecessary delay, but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security (the "Exchange Date"), the Issuer shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary global Security, executed by the Issuer.  On or after
the Exchange Date, such temporary global Security shall be surrendered by the
Common Depositary to the Trustee, as the Issuer's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities
without charge, and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary global Security, an equal aggregate principal
amount of 

                                     - 21 -
<PAGE>
 
definitive Securities of the same series of authorized denominations and of like
tenor as the portion of such temporary global Security to be exchanged. The
definitive Securities to be delivered in exchange for any such temporary global
Security shall be in bearer form, registered form, permanent global bearer form
or permanent global registered form, or any combination thereof, as specified as
contemplated by Section 301, and, if any combination thereof is so specified, as
requested by the beneficial owner thereof; provided, however, that, unless
otherwise specified in such temporary global Security, upon such presentation by
the Common Depositary, such temporary global Security is accompanied by a
certificate dated the Exchange Date or a subsequent date and signed by Euroclear
as to the portion of such temporary global Security held for its account then to
be exchanged and a certificate dated the Exchange Date or a subsequent date and
signed by CEDEL as to the portion of such temporary global Security held for its
account then to be exchanged, each in the form set forth in Exhibit A-2 to this
Indenture or in such other form as may be established pursuant to Section 301;
and provided further that definitive Bearer Securities shall be delivered in
exchange for a portion of a temporary global Security only in compliance with
the requirements of Section 303.

          Unless otherwise specified in such temporary global Security, the
interest of a beneficial owner of Securities of a series in a temporary global
Security shall be exchanged for definitive Securities of the same series and of
like tenor following the Exchange Date when the account holder instructs
Euroclear or CEDEL, as the case may be, to request such exchange on his behalf
and delivers to Euroclear or CEDEL, as the case may be, a certificate in the
form set forth in Exhibit A-1 to this Indenture (or in such other form as may be
established pursuant to Section 301), dated no earlier than 15 days prior to the
Exchange Date, copies of which certificate shall be available from the offices
of Euroclear and CEDEL, the Trustee, any Authenticating Agent appointed for such
series of Securities and each Paying Agent.  Unless otherwise specified in such
temporary global Security, any such exchange shall be made free of charge to the
beneficial owners of such temporary global Security, except that a Person
receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like unless such Person takes delivery of such definitive
Securities in person at the offices of Euroclear or CEDEL.  Definitive
Securities in bearer form to be delivered in exchange for any portion of a
temporary global Security shall be delivered only outside the United States.

          Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary global
Security on an Interest Payment Date for Securities of such series occurring
prior to the applicable Exchange Date shall be payable to Euroclear and CEDEL on
such Interest Payment Date upon delivery by Euroclear and CEDEL to the Trustee
of a certificate or certificates in the form set forth in Exhibit A-2 to this
Indenture (or in such other forms as may be established pursuant to Section
301), for credit without further interest on or after such Interest Payment Date
to the respective accounts of Persons who are the beneficial owners of such
temporary global Security on such Interest Payment Date and who have each
delivered to Euroclear or CEDEL, as the case may be, a certificate dated no
earlier than 15 days prior to the Interest Payment Date occurring prior to such
Exchange Date in the form set forth as Exhibit A-1 to this Indenture (or in such
other forms as may be established pursuant to Section 301).  Notwithstanding
anything to the contrary herein contained, the certifications made pursuant to
this paragraph shall satisfy the certification requirements of the preceding two
paragraphs of this Section 304(b) and of the third paragraph of Section 303 of
this Indenture and the interests of the Persons who are the beneficial owners of
the temporary global Security with respect to which such certification was made
will be exchanged for definitive Securities of the same series and of like tenor
on the Exchange Date or the date of certification if such date occurs after the
Exchange Date, without further act or deed by such beneficial owners.  Except as
otherwise provided in this paragraph, no payments of principal or interest owing
with respect to a beneficial interest in a temporary global Security will be
made unless and until such interest in such temporary global Security shall have
been exchanged for an interest in a definitive Security. Any interest so
received by Euroclear and CEDEL and not paid as herein provided shall be
returned to 

                                     - 22 -
<PAGE>
 
the Trustee prior to the expiration of two years after such Interest Payment
Date in order to be repaid to the Issuer.

          (c) Unless otherwise provided in or pursuant to a Board Resolution,
this Section 304(c) shall govern the exchange of temporary Securities issued in
global form through the facilities of DTC.  If any such temporary Security is
issued in global form, then such temporary global security shall, unless
otherwise provided therein, be delivered to DTC for credit to the respective
accounts of the beneficial owners of such Securities (or to such other accounts
as they may direct).

          Without unnecessary delay, but in any event not later than the
Exchange Date, the Issuer shall deliver to the Trustee definitive Securities, in
aggregate principal amount equal to the principal amount of such temporary
global Security, executed by the Issuer.  On or after the Exchange Date, such
temporary global Security shall be surrendered by DTC to the Trustee, as the
Issuer's agent for such purpose, to be exchanged, in whole or from time to time
in part, for definitive Securities without charge, and the Trustee shall
authenticate and deliver, in exchange for each portion of such temporary global
Security, an equal aggregate principal amount of definitive Securities of the
same series of authorized denominations and of like tenor as the portion of such
temporary global Security to be exchanged.  The definitive Securities to be
delivered in exchange for any such temporary global Security shall be in
registered form or permanent global registered form, or any combination thereof,
as specified as contemplated by Section 301, and, if any combination thereof is
so specified, as requested by the beneficial owner thereof.

          Unless otherwise specified in such temporary global Security, the
interest of a beneficial owner of Securities of a series in a temporary global
Security shall be exchanged for definitive Securities of the same series and of
like tenor following the Exchange Date when the account holder instructs DTC to
request such exchange on his behalf.  Unless otherwise specified in such
temporary global Security, any such exchange shall be made free of charge to the
beneficial owners of such temporary global Security, except that a Person
receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like unless such Person takes delivery of such definitive
Securities in person.

          Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary global
Security on an Interest Payment Date for Securities for such series occurring
prior to the applicable Exchange Date shall be payable to DTC on such Interest
Payment Date, for credit without further interest on or after such Interest
Payment Date to the respective accounts of Persons who are the beneficial owners
of such temporary global Security on such Interest Payment Date.

          SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE. The 
Issuer shall cause to be kept at the Corporate Trust Office of the Trustee or in
any office or agency of the Issuer in a Place of Payment a register for each
series of Securities (the registers maintained in such office or in any such
office or agency of the Issuer in a Place of Payment being herein sometimes
referred to collectively as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Issuer shall provide for the
registration of Registered Securities and of transfers of Registered Securities.
The Security Register shall be in written form or any other form capable of
being converted into written form within a reasonable time. The Trustee, at its
Corporate Trust Office, is hereby appointed "Security Registrar" for the purpose
of registering Registered Securities and transfers of Registered Securities on
such Security Register as herein provided. The Issuer shall have the right to
remove and replace from time to time the Security Registrar for any series of
Securities; provided that no such removal or replacement shall be effective
until a successor Security Registrar with respect to such series of Securities
shall have been appointed by the Issuer and shall have accepted such appointment
by the Issuer. In the event that


                                     - 23 -
<PAGE>
 
the Trustee shall cease to be Security Registrar, it shall have the right to
examine the Security Register at all reasonable times.

          Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Security of any series at any office
or agency of the Issuer in a Place of Payment for that series, the Issuer shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Registered Securities of
the same series, of any authorized denominations and of a like aggregate
principal amount, bearing a number not contemporaneously outstanding, and
containing identical terms and provisions.  Whenever any such Registered
Securities are so surrendered for exchange, the Issuer shall execute, and the
Trustee shall authenticate and deliver, the Registered Securities which the
Holder making the exchange is entitled to receive.

          Unless otherwise specified with respect to any series of Securities as
contemplated by Section 301, Bearer Securities may not be issued in exchange for
Registered Securities.  If (but only if) permitted by the applicable Board
Resolution and (subject to Section 303) set forth in the  applicable Officers'
Certificate, or in any indenture supplemental hereto, delivered as contemplated
by Section 301, at the option of the Holder, Bearer Securities of any series may
be exchanged for Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount and tenor, upon surrender
of the Bearer Securities to be exchanged at any such office or agency, with all
unmatured coupons and all matured coupons in default thereto appertaining. If
the Holder of a Bearer Security is unable to produce any such unmatured coupon
or coupons or matured coupon or coupons in default, any such permitted exchange
may be effected if the Bearer Securities are accompanied by payment in funds
acceptable to the Issuer in an amount equal to the face amount of such missing
coupon or coupons, or the surrender of such missing coupon or coupons may be
waived by the Issuer and the Trustee if there is furnished to them such security
or indemnity as they may require to save each of them and any Paying Agent
harmless. If thereafter the Holder of such Security shall surrender to any
Paying Agent any such missing coupon in respect of which such a payment shall
have been made, such Holder shall be entitled to receive the amount of such
payment; provided, however, that, except as otherwise provided in Section 1002,
interest represented by coupons shall be payable only upon presentation and
surrender of those coupons at an office or agency located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such office or agency in a permitted exchange for a
Registered Security of the same series and like tenor after the close of
business at such office or agency on (i) any Regular Record Date and before the
opening of business at such office or agency on the relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related proposed date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture. Whenever any Securities are so
surrendered for exchange, the Issuer shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

          If provided as contemplated by Section 301, at the option of the
Holder, Registered Securities of such series may be exchanged for Bearer
Securities upon such terms and conditions as may be provided in or pursuant to
this Indenture with respect to such series.  Whenever any Securities are so
surrendered for exchange, the Issuer shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

          Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent global Security shall be exchangeable
only as provided in this paragraph.  If the depositary for any permanent global
Security is DTC, then unless the terms of such global Security expressly
permit such global Security to be exchanged in whole or in part for 

                                     - 24 -
<PAGE>
 
definitive Securities, a global Security may be transferred, in whole but not in
part, only to a nominee of DTC, or by a nominee of DTC to DTC, or to a successor
to DTC for such global Security elected or approved by the Issuer or to a
nominee of such successor to DTC. If at any time DTC notifies the Issuer that it
is unwilling or unable to continue as depositary for the applicable global
Security or Securities or if at any time DTC ceases to be a clearing agency
registered under the Exchange Act if so required by applicable law or
regulation, the Issuer shall appoint a successor depositary with respect to such
global Security or Securities. If (x) a successor depositary for such global
Security or Securities is not appointed by the Issuer within 90 days after the
Issuer receives such notice or becomes aware of such unwillingness, inability or
ineligibility, (y) an Event of Default has occurred and is continuing and the
beneficial owners representing a majority in principal amount of the applicable
series of Securities represented by such global Security or Securities advise
DTC to cease acting as depositary for such global Security or Securities or (z)
the Issuer, in its sole discretion, determines at any time that all Outstanding
Securities (but not less than all) of any series issued or issuable in the form
of one or more global Securities shall no longer be represented by such global
Security or Securities, then the Issuer shall execute, and the Trustee shall
authenticate and deliver definitive Securities of like series, rank, tenor and
terms in definitive form in an aggregate principal amount equal to the principal
amount of such global Security or Securities. The Issuer and the Trustee shall
be entitled to rely conclusively on information provided by DTC as to the names
of the beneficial holders and the amounts owned by such holders. If any
beneficial owner of an interest in a permanent global Security is otherwise
entitled to exchange such interest for Securities of such series and of like
tenor and principal amount of another authorized form and denomination, as
specified as contemplated by Section 301 and provided that any applicable notice
provided in the permanent global Security shall have been given, then without
unnecessary delay but in any event not later than the earliest day on which such
interest may be so exchanged, the Issuer shall execute, and the Trustee shall
authenticate and deliver definitive Securities in aggregate principal amount
equal to the principal amount of such beneficial owner's interest in such
permanent global Security. On or after the earliest date on which such interests
may be so exchanged, such permanent global Security shall be surrendered for
exchange by DTC or such other depositary as shall be specified in the Issuer
Order with respect thereto to the Trustee, as the Issuer's agent for such
purpose, provided, however, that no such exchanges may occur during a period
beginning at the opening of business 15 days before any selection of Securities
to be redeemed and ending on the relevant Redemption Date if the Security for
which exchange is requested may be among those selected for redemption; and
provided further that no Bearer Security delivered in exchange for a portion of
a permanent global Security shall be mailed or otherwise delivered to any
location in the United States. If a Registered Security is issued in exchange
for any portion of a permanent global Security after the close of business at
the office or agency where such exchange occurs on (i) any Regular Record Date
and before the opening of business at such office or agency on the relevant
Interest Payment Date, or (ii) any Special Record Date and the opening of
business at such office or agency on the related proposed date for payment of
Defaulted Interest, interest or Defaulted Interest, as the case may be, will not
be payable on such Interest Payment Date or proposed date for payment, as the
case may be, in respect of such Registered Security, but will be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to
the Person to whom interest in respect of such portion of such permanent global
Security is payable in accordance with the provisions of this Indenture.

          All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Issuer, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

          Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Issuer or
the Security Registrar) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Issuer and the Security
Registrar, duly executed by the Holder thereof or his attorney duly authorized
in writing.

                                     - 25 -
<PAGE>
 
          No service charge shall be made for any registration of transfer or
exchange of Securities, but the Issuer may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Sections 304, 906, 1107 or 1305 not involving any
transfer.

          Except as otherwise provided in or pursuant to this Indenture, the
Issuer or the Trustee, as applicable, shall not be required (i) to issue,
register the transfer of or exchange any Security if such Security may be among
those selected for redemption during a period beginning at the opening of
business 15 days before selection of the Securities to be redeemed under Section
1103 and ending at the close of business on (A) if such Securities are issuable
only as Registered Securities, the day of the mailing of the relevant notice of
redemption and (B) if such Securities are issuable as Bearer Securities, the day
of the first publication of the relevant notice of redemption or, if such
Securities are also issuable as Registered Securities and there is no
publication, the mailing of the relevant notice of redemption, or (ii) to
register the transfer of or exchange any Registered Security so selected for
redemption in whole or in part, except, in the case of any Registered Security
to be redeemed in part, the portion thereof not to be redeemed, or (iii) to
exchange any Bearer Security so selected for redemption except that such a
Bearer Security may be exchanged for a Registered Security of that series and
like tenor, provided that such Registered Security shall be simultaneously
surrendered for redemption, or (iv) to issue, register the transfer of or
exchange any Security which has been surrendered for repayment at the option of
the Holder, except the portion, if any, of such Security not to be so repaid.

          SECTION 306. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES. If any
mutilated Security or a Security with a mutilated coupon appertaining to it is
surrendered to the Trustee or the Issuer, together with, in proper cases, such
security or indemnity as may be required by the Issuer or the Trustee to save
each of them and any agent of either of them harmless, the Issuer shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new
Security of the same series and principal amount, containing identical terms and
provisions and bearing a number not contemporaneously outstanding, with coupons
corresponding to the coupons, if any, appertaining to the surrendered Security.

          If there shall be delivered to the Issuer and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or coupon, and (ii) such security or indemnity as may be required by them to
save each of them and any agent of either of them harmless, then, in the absence
of notice to the Issuer or the Trustee that such Security or coupon has been
acquired by a bona fide purchaser, the Issuer shall execute and upon its request
the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost
or stolen Security or in exchange for the Security to which a destroyed, lost or
stolen coupon appertains (with all appurtenant coupons not destroyed, lost or
stolen), a new Security of the same series and principal amount, containing
identical terms and provisions and bearing a number not contemporaneously
outstanding, with coupons corresponding to the coupons, if any, appertaining to
such destroyed, lost or stolen Security or to the Security to which such
destroyed, lost or stolen coupon appertains.

          Notwithstanding the provisions of the previous two paragraphs, in case
any such mutilated, destroyed, lost or stolen Security or coupon has become or
is about to become due and payable, the Issuer in its discretion may, instead of
issuing a new Security, with coupons corresponding to the coupons, if any,
appertaining to such destroyed, lost or stolen Security or to the Security to
which such destroyed, lost or stolen coupon appertains, pay such Security or
coupon, provided, however, that payment of principal of (and premium or Make-
Whole Amount, if any), and interest on and any Additional Amounts with respect
to, Bearer Securities shall, except as otherwise provided in Section 1002, be
payable only at an office or agency located outside the United States and,
unless otherwise specified as contemplated by Section 301, any interest in
Bearer Securities shall be payable only upon presentation and surrender of the
coupons appertaining thereto.

                                     - 26 -
<PAGE>
 
          Upon the issuance of any new Security under this Section, the Issuer
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

          Every new Security of any series with its coupons, if any, issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security, or
in exchange for a Security to which a destroyed, lost or stolen coupon
appertains, shall constitute an original additional contractual obligation of
the Issuer, whether or not the destroyed, lost or stolen Security and its
coupons, if any, or the destroyed, lost or stolen coupon shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of that
series and their coupons, if any, duly issued thereunder.

          The provisions of this Section, as amended or supplemented, are
exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities or coupons.

          SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS RESERVED. Except as
otherwise specified with respect to a series of Securities in accordance with
the provisions of Section 301, interest on and Additional Amounts with respect
to any Registered Security that is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest at the office or
agency of the Issuer maintained for such purpose pursuant to Section 1002;
provided, however, that each installment of interest on any Registered Security
may at the Issuer's option be paid by (i) mailing a check for such interest,
payable to or upon the written order of the Person entitled thereto pursuant to
Section 308, to the address of such Person as it appears on the Security
Register or (ii) transfer to an account maintained by the payee located inside
the United States.

          Unless otherwise provided as contemplated by Section 301 with respect
to the Securities of any series, payment of interest may be made, in the case of
a Bearer Security, by transfer to an account maintained by the payee with a bank
located outside the United States.

          Unless otherwise provided as contemplated by Section 301, every
permanent global Security will provide that interest, if any, payable on any
Interest Payment Date will be paid to DTC, Euroclear and/or CEDEL, as the case
may be, with respect to that portion of such permanent global Security held for
its account by Cede & Co.  or the Common Depositary, as the case may be, for the
purpose of permitting such party to credit the interest received by it in
respect of such permanent global Security to the accounts of the beneficial
owners thereof.

          In case a Bearer Security of any series is surrendered in exchange for
a Registered Security of such series after the close of business (at an office
or agency in a Place of Payment for such series) on any Regular Record Date and
before the opening of business (at such office or agency) on the next succeeding
Interest Payment Date, such Bearer Security shall be surrendered without the
coupon relating to such Interest Payment Date and interest will not be payable
on such Interest Payment Date in respect of the Registered Security issued in
exchange for such Bearer Security, but will be payable only to the Holder of
such coupon when due in accordance with the provisions of this Indenture.

          Except as otherwise specified with respect to a series of Securities
in accordance with the provisions of Section 301, any interest on any Registered
Security of any series that is payable, but is not punctually paid or duly
provided for, on any Interest Payment Date (herein called "Defaulted Interest")
shall forthwith cease to be payable to the registered Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Issuer, at its election in each case, as
provided in clause (A) or (B) below:

                                     - 27 -
<PAGE>
 
                    (A) The Issuer may elect to make payment of any Defaulted
          Interest to the Persons in whose names the Registered Securities of
          such series (or their respective Predecessor Securities) are
          registered at the close of business on a Special Record Date for the
          payment of such Defaulted Interest, which shall be fixed in the
          following manner.  The Issuer shall notify the Trustee in writing of
          the amount of Defaulted Interest proposed to be paid on each
          Registered Security of such series and the date of the proposed
          payment (which shall not be less than 20 days after such notice is
          received by the Trustee), and at the same time the Issuer shall
          deposit with the Trustee an amount of money in the currency or
          currencies, currency unit or units or composite currency or currencies
          in which the Securities of such series are payable (except as
          otherwise specified pursuant to Section 301 for the Securities of such
          series) equal to the aggregate amount proposed to be paid in respect
          of such Defaulted Interest or shall make arrangements satisfactory to
          the Trustee for such deposit on or prior to the date of the proposed
          payment, such money when deposited to be held in trust for the benefit
          of the Persons entitled to such Defaulted Interest as provided in this
          clause.  Thereupon the Trustee shall fix a Special Record Date for the
          payment of such Defaulted Interest which shall be not more than 15
          days and not less than 10 days prior to the date of the proposed
          payment and not less than 10 days after the receipt by the Trustee of
          the notice of the proposed payment.  The Trustee shall promptly notify
          the Issuer of such Special Record Date and, in the name and at the
          expense of the Issuer, shall cause notice of the proposed payment of
          such Defaulted Interest and the Special Record Date therefor to be
          mailed, first class postage prepaid, to each Holder of Registered
          Securities of such series at his address as it appears in the Security
          Register not less than 10 days prior to such Special Record Date. The
          Trustee may, in its discretion, in the name and at the expense of the
          Issuer, cause a similar notice to be published at least once in an
          Authorized Newspaper in each Place of Payment, but such publications
          shall not be a condition precedent to the establishment of such
          Special Record Date. Notice of the proposed payment of such Defaulted
          Interest and the Special Record Date therefore having been mailed as
          aforesaid, such Defaulted Interest shall be paid to the Persons in
          whose names the Registered Securities of such series (or their
          respective Predecessor Securities) are registered at the close of
          business on such Special Record Date and shall no longer be payable
          pursuant to the following clause (B). In case a Bearer Security of any
          series is surrendered at the office or agency in a Place of Payment
          for such series in exchange for a Registered Security of such series
          after the close of business at such office or agency on any Special
          Record Date and before the opening of business at such office or
          agency on the related proposed date for payment of Defaulted Interest,
          such Bearer Security shall be surrendered without the coupon relating
          to such proposed date of payment and Defaulted Interest will not be
          payable on such proposed date of payment in respect of the Registered
          Security issued in exchange for such Bearer Security, but will be
          payable only to the Holder of such coupon when due in accordance with
          the provisions of this Indenture.

                    (B) The Issuer may make payment of any Defaulted Interest on
          the Registered Securities of any series in any other lawful manner not
          inconsistent with the requirements of any securities exchange on which
          such Securities may be listed, and upon such notice as may be required
          by such exchange, if, after notice given by the Issuer to the Trustee
          of the proposed payment pursuant to this clause, such manner of
          payment shall be deemed practicable by the Trustee.

          Subject to the foregoing provisions of this Section and Section 305,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

          SECTION 308.  PERSONS DEEMED OWNERS.  Prior to due presentment of a
Registered Security for registration of transfer, the Issuer, the Trustee and
any agent of the Issuer or the Trustee may treat the Person in whose name such
Registered Security is registered as the owner of such Security for the
purpose of receiving payment of principal of (and premium or Make-Whole Amount,
if any), and (subject to Sections 305 and 307) interest on and any Additional
Amounts with respect to such Registered Security and for all other purposes
whatsoever, whether or not such Registered Security be overdue, and neither the
Issuer, the Trustee nor any agent of the Issuer or the Trustee shall be affected
by notice to the contrary.

          Title to any Bearer Security and any coupons appertaining thereto
shall pass by delivery.  The Issuer, the Trustee and any agent of the Issuer or
the Trustee may treat the Holder of any Bearer Security and the Holder of any
coupon as the absolute owner of such Security or coupon for the purpose of
receiving any payment with respect to payment thereof or on account thereof and
for all other purposes whatsoever, whether or not any payment with respect to
such Security or coupon be overdue, and neither the Issuer, the Trustee nor any
agent of the Issuer or the Trustee shall be affected by notice to the contrary.

          No Holder of any beneficial interest in any global Security held on
its behalf by a depositary shall have any rights under this Indenture with
respect to such global Security, and such depositary may be treated by the
Issuer, the Trustee, and any agent of the Issuer or the Trustee as the owner of
such global Security for all purposes whatsoever.  None of the Issuer, the
Trustee, any Paying Agent or the Security Registrar will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests of a Security in global form or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.

          Notwithstanding the foregoing, with respect to any global Security,
nothing herein shall prevent the Issuer, the Trustee, or any agent of the Issuer
or the Trustee, from giving effect to any written certification, proxy or other
authorization furnished by any depositary, as a Holder, with respect to such
global Security or impair, as between such depositary and owners of beneficial
interests in such global Security, the operation of customary practices
governing the exercise of the rights of such depositary (or its nominee) as
Holder of such global Security.

          SECTION 309.  CANCELLATION.  All Securities and coupons surrendered
for payment, redemption, repayment at the option of the Holder, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee,
and any such Securities and coupons and Securities and coupons surrendered
directly to the Trustee for any such purpose shall be promptly canceled by it;
provided, however, where the Place of Payment is located outside of the United
States, the Paying Agent at such Place of Payment may cancel the Securities
surrendered to it for such purposes prior to delivering the Securities to the
Trustee.  The Issuer may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Issuer may
have acquired in any manner whatsoever, and may deliver to the Trustee (or to
any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Issuer has not issued and sold, and
all Securities so delivered shall be promptly canceled by the Trustee. If the
Issuer shall so acquire any of the Securities, however, such acquisition shall
not operate as a redemption or satisfaction of the indebtedness represented by
such Securities unless and until the same are surrendered to the Trustee for
cancellation. No Securities shall be authenticated in lieu of or in exchange for
any Securities canceled as provided in this Section, except as expressly
permitted by this Indenture. Canceled Securities and coupons held by the Trustee
shall be periodically destroyed by the Trustee and the Trustee shall deliver a
certificate of such destruction to the Issuer, unless by an Issuer Order the
Issuer directs their return to it.

          SECTION 310.  COMPUTATION OF INTEREST.  Except as otherwise specified
as contemplated by Section 301 with respect to Securities of any series,
interest on the Securities shall be computed on the basis of a 360-day year
consisting of twelve 30-day months.

                           SATISFACTION AND DISCHARGE

     SECTION 401.  SATISFACTION AND DISCHARGE OF INDENTURE.  This Indenture
shall upon Issuer Request cease to be of further effect with respect to any
series of  Securities specified in such Issuer Request (except as to any
surviving rights of registration of transfer or exchange of Securities of such
series herein expressly provided for and any right to receive Additional
Amounts, as provided in Section 1012), and the Trustee, upon receipt of an
Issuer Order, and at the expense of the Issuer, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture as to such series
when

          (a)  either

               (1)  all Securities of such series theretofore authenticated and
                    delivered and all coupons, if any, appertaining thereto
                    (other than (i) coupons appertaining to Bearer Securities
                    surrendered in exchange for Registered Securities and
                    maturing after such exchange, whose surrender is not
                    required or has been waived as provided in Section 305, (ii)
                    Securities and coupons of such series which have been
                    destroyed, lost or stolen and which have been replaced or
                    paid as provided in Section 306, (iii) coupons appertaining
                    to Securities called for redemption and maturing after the
                    relevant Redemption Date, whose surrender has been waived as
                    provided in Section 1106, and (iv) Securities and coupons of
                    such series for whose payment money has theretofore been
                    deposited in trust or segregated and held in trust by the
                    Issuer and thereafter repaid to the Issuer or discharged
                    from such Trust, as provided in Section 1003) have been
                    delivered to the Trustee for cancellation; or

               (2)  all Securities of such series and, in the case of (A) or
                    (B) below, any coupons appertaining thereto not theretofore
                    delivered to the Trustee for cancellation

                    (A)  have become due and payable, or

                    (B)  will become due and payable at their Stated Maturity 
                         within one year, or

                    (C)  if redeemable at the option of the Issuer, are to be
                         called for redemption within one year under
                         arrangements satisfactory to the Trustee for the giving
                         of notice of redemption by the Trustee in the name, and
                         at the expense, of the Issuer,

                    and the Issuer, in the case of (A), (B) or (C) above, has
                    irrevocably deposited or caused to be deposited with the
                    Trustee as trust funds in trust for such purpose an amount
                    in the currency or currencies, currency unit or units or
                    composite currency or currencies in which the Securities of
                    such series are payable, sufficient to pay and discharge
                    the entire indebtedness on such Securities and such coupons
                    not theretofore delivered to the Trustee for cancellation,
                    for principal (and premium or Make-Whole Amount, if any)
                    and interest, and any Additional Amounts with respect
                    thereto, to the date of such deposit (in the case of
                    Securities which have become due and payable) or to the
                    Stated Maturity or Redemption Date, as the case may be,

          (b)  the Issuer has paid or caused to be paid all other sums payable
               hereunder by the Issuer; and

                                     - 30 -
<PAGE>
 
          (c)  the Issuer has delivered to the Trustee an Officers' Certificate
               and an Opinion of Counsel, each stating that all conditions
               precedent herein provided for relating to the satisfaction and
               discharge of this Indenture as to such series have been complied
               with.

          Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Issuer to the Trustee and any predecessor Trustee under
Section 606, the obligations of the Issuer to any Authenticating Agent under
Section 611 and, if money shall have been deposited with and held by the Trustee
pursuant to subclause (B) of clause (1) of this Section, the obligations of the
Trustee under Section 402 and the last paragraph of Section 1003 shall survive.

          SECTION 402.  APPLICATION OF TRUST FUNDS. Subject to the provisions
of the last paragraph of Section 1003, all money and Government Obligations
deposited with the Trustee pursuant to Section 401 or Article 14 shall be held
in trust and applied by it, in accordance with the provisions of the Securities,
the coupons and this Indenture, to the payment, either directly or through any
Paying Agent (including the Issuer acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal (and
premium or Make-Whole Amount, if any), and any interest and Additional Amounts
for whose payment such money has or Government Obligations have been deposited
with or received by the Trustee, but such money and Government Obligations need
not be segregated from other funds except to the extent required by law.

                                    REMEDIES

          SECTION 501.  EVENTS OF DEFAULT.  "Event of Default," wherever used
herein  with respect to any particular series of Securities, means any one of
the following events (whatever the reason for such Event of Default and whether
or not it shall be voluntary or involuntary or be effected by operation of law
or pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body) unless such event is
specifically deleted or modified in or pursuant to the supplemental indenture,
Board Resolution or Officers' Certificate establishing the terms of such series
pursuant to this Indenture:

          (a)  default in the payment of any interest upon or any Additional
               Amounts payable in respect of any Security of that series or of
               any coupon appertaining thereto, when such interest or Additional
               Amounts or coupon becomes due and payable, and continuance of
               such default for a period of 30 days; or

          (b)  default in the payment of the principal of (or premium or Make-
               Whole Amount, if any, on) any Security of that series when it
               becomes due and payable at its Maturity; or

          (c)  default in the deposit of any sinking fund payment, when and as
               due by the terms of any Security of that series; or

          (d)  default in the performance, or breach, of any covenant or
               warranty of the Issuer in this Indenture with respect to any
               Security of that series (other than a covenant or warranty a
               default in the performance or the breach of which is elsewhere in
               this Section specifically dealt with), and continuance of such
               default or breach for a period of 60 days after there has been
               given, by registered or certified mail, to the Issuer by the
               Trustee or to the Issuer and the Trustee by the Holders of at
               least 25% in principal amount of the Outstanding Securities of
               that series, a written notice specifying such default or breach
               and requiring it to be remedied and stating that such notice is a
               "Notice of Default" hereunder; or

                                     - 31 -
<PAGE>
 
          (e)  a default under any evidence of Recourse Indebtedness of the
               Issuer, or under any mortgage, indenture or other instrument of
               the Issuer (including a default with respect to Securities of any
               series other than that series) under which there may be issued or
               by which there may be secured any Recourse Indebtedness of the
               Issuer (or by any Subsidiary, the repayment of which the Issuer
               has guaranteed or for which the Issuer is directly responsible or
               liable as obligor or guarantor), whether such Recourse Debt now
               exists or shall hereafter be created, which default shall
               constitute a failure to pay an aggregate principal amount
               exceeding $5,000,000 of such indebtedness when due and payable
               after the expiration of any applicable grace period with respect
               thereto and shall have resulted in such indebtedness in an
               aggregate principal amount exceeding $5,000,000 becoming or being
               declared due and payable prior to the date on which it would
               otherwise have become due and payable, without such indebtedness
               having been discharged, or such acceleration having been
               rescinded or annulled, within a period of 10 days after there
               shall have been given, by registered or certified mail, to the
               Issuer by the Trustee or to the Issuer and the Trustee by the
               Holders of at least 25% in principal amount of the Outstanding
               Securities of that series of a written notice specifying such
               default and requiring the Issuer to cause such indebtedness to be
               discharged or cause such acceleration to be rescinded or annulled
               and stating that such notice is a "Notice of Default" hereunder;
               or

          (f)  the Issuer or any Significant Subsidiary pursuant to or within
               the meaning of any Bankruptcy Law:

               (1)  commences a voluntary case;

               (2)  consents to the entry of an order for relief against it in
                    an involuntary case;

               (3)  consents to the appointment of a Custodian of it or for all
                    or substantially all of its property; or

               (4)  makes a general assignment for the benefit of its creditors;
                    or

          (g)  a court of competent jurisdiction enters an order or decree under
               any Bankruptcy Law that:

               (1)  is for relief against the Issuer or any Significant
                    Subsidiary in an involuntary case,

               (2)  appoints a Custodian of the Issuer or any Significant
                    Subsidiary or for all or substantially all of either of its
                    property, or

               (3)  orders the liquidation of the Issuer or any Significant
                    Subsidiary, and the order or decree remains unstayed and in
                    effect for 90 days; or

          (h)  any other Event of Default provided in or pursuant to this
               Indenture with respect to Securities of that series.

As used in this Section 501, the term "Bankruptcy Law" means title 11, U.S.
Code or any similar Federal or state law for the relief of debtors and the term
"Custodian" means any receiver, trustee, assignee, liquidator or other similar
official under any Bankruptcy Law.

          SECTION 502.  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.  If
an Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then and in every such case the Trustee or
the Holders of not 

                                     - 32 -
<PAGE>
 
less than 25% in principal amount of the Outstanding Securities of that series
may declare the principal (or, if any Securities are Original Issue Discount
Securities or Indexed Securities, such portion of the principal as may be
specified in the terms thereof) of all the Securities of that series to be due
and payable immediately, by a notice in writing to the Issuer (and to the
Trustee if given, or such lesser amount as may be provided for in the Securities
of such series, by the Holders), and upon any such declaration such principal or
such lesser amount shall become immediately due and payable.

          At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of not less than a majority in principal amount of
the Outstanding Securities of that series, by written notice to the Issuer and
the Trustee, may rescind and annul such declaration and its consequences if:

          (a)  the Issuer has paid or deposited with the Trustee a sum
               sufficient to pay in the currency or currency unit or composite
               currency in which the Securities of such series are payable
               (except as otherwise specified pursuant to Section 301 for the
               Securities of such series):

               (1)  all overdue installments of interest on and any Additional
                    Amounts payable in respect of all Outstanding Securities of
                    that series and any related coupons,

               (2)  the principal of (and premium or Make-Whole Amount, if any,
                    on) any Outstanding Securities of that series which have
                    become due otherwise than by such declaration of
                    acceleration and interest thereon and any Additional Amounts
                    with respect thereto at the rate or rates borne by or
                    provided for in such Securities,

               (3)  to the extent that payment of such interest or Additional
                    Amounts is lawful, interest upon overdue installments of
                    interest and any Additional Amounts at the rate or rates
                    borne by or provided for in such Securities, and

               (4)  all sums paid or advanced by the Trustee hereunder and the
                    reasonable compensation, expenses, disbursements and
                    advances of the Trustee, its agents and counsel; and

          (b)  all Events of Default with respect to Securities of that series,
               other than the nonpayment of the principal of (or premium or 
               Make-Whole Amount, if any) or interest on, and any Additional
               Amounts with respect to Securities of that series which have
               become due solely by such declaration of acceleration, have been
               cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

     SECTION 503.  COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
TRUSTEE.  The Issuer covenants that if:

          (a)  default is made in the payment of any installment of interest or
               Additional Amounts, if any, on any Security of any series and any
               related coupon when such interest or Additional Amount becomes
               due and payable and such default continues for a period of 30
               days, or

          (b)  default is made in the payment of the principal of (or premium or
               Make-Whole Amount, if any, on) any Security of any series at its
               Maturity,

                                     - 33 -
<PAGE>
 
then the Issuer will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities of such series and coupons, the whole
amount then due and payable on such Securities and coupons for principal (and
premium or Make-Whole Amount, if any) and interest and Additional Amounts, with
interest upon any overdue principal (and premium or Make-Whole Amount, if any)
and, to the extent that payment of such interest shall be legally enforceable,
upon any overdue installments of interest or Additional Amounts, if any, at the
rate or rates borne by or provided for in such Securities, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

          If the Issuer fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Issuer or any other obligor upon such Securities and any related
coupons and collect the monies adjudged or decreed to be payable in the manner
provided by law out of the property of the Issuer or any other obligor upon such
Securities and any related coupons wherever situated.

          If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series
and any related coupons by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights, whether for
the specific enforcement of any covenant or agreement in this Indenture or in
aid of the exercise of any power granted herein or therein, or to enforce any
other proper remedy.

          SECTION 504.  TRUSTEE MAY FILE PROOFS OF CLAIM.  In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Issuer or any other obligor upon the Securities or
the property of the Issuer or of such other obligor or their creditors, the
Trustee (irrespective of whether the principal of the Securities of any series
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Issuer for the payment of overdue principal, premium or Make-Whole Amount,
if any, or interest or Additional Amounts) shall be entitled and empowered, by
intervention in such proceeding or otherwise:

          (a)  to file and prove a claim for the whole amount, or such lesser
               amount as may be provided for in the Securities of such series,
               of principal (and premium or Make-Whole Amount, if any) and
               interest and Additional Amounts, if any, owing and unpaid in
               respect of the Securities and any related coupons and to file
               such other claims of the Trustee (including any claim for the
               reasonable compensation, expenses, disbursements and advances of
               the Trustee, its agents and counsel) and of the Holders allowed
               in such judicial proceeding, and

          (b)  to collect and receive any monies of other property payable or
               deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator (or
other similar official) in any such judicial proceeding is hereby authorized by
each Holder of the Securities of such series and coupons to make such payments
to the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee and any predecessor Trustee, their agents and counsel, and any other
amounts due the Trustee or any predecessor Trustee under Section 606.

                                     - 34 -
<PAGE>
 
          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
or coupon any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or coupons or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder of a
Security or coupon in any such proceeding.

          SECTION 505.  TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF
SECURITIES OR COUPONS.  All rights of action and claims under this Indenture or
any of the Securities or coupons may be prosecuted and enforced by the Trustee
without the possession of any of the Securities or coupons or the production
thereof in any proceeding relating thereto, and any such proceeding instituted
by the Trustee shall be brought in its own name as trustee of an express trust,
and any recovery of judgment shall, after provision for the payment of the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, be for the ratable benefit of the Holders of the
Securities and coupons in respect of which such judgment has been recovered.

          SECTION 506.  APPLICATION OF MONEY COLLECTED.  Any money collected by
the Trustee pursuant to this Article shall be applied in the following order, at
the date or dates fixed by the Trustee and, in case of the distribution of such
money on account of principal (or premium or Make-Whole Amount, if any) or
interest and any Additional Amounts, upon presentation of the Securities or
coupons, or both, as the case may be, and the notation thereon of the payment if
only partially paid and upon surrender thereof if fully paid:

          FIRST:  To the payment of all amounts due the Trustee and any
     predecessor Trustee under Section 606;

          SECOND:  To the payment of the amounts then due and unpaid upon the
     Securities and coupons for principal (and premium or Make-Whole Amount, if
     any) and interest and any Additional Amounts payable, in respect of which
     or for the benefit of which such money has been collected, ratably, without
     preference or priority of any kind, according to the aggregate amounts due
     and payable on such Securities and coupons for principal (and premium or
     Make-Whole Amount, if any), interest and Additional Amounts, respectively;
     and

          THIRD:  The balance, if any, to the Issuer.

          SECTION 507.  LIMITATION ON SUITS.  No Holder of any Security of any
series or any related coupon shall have any right to institute any proceeding,
judicial or otherwise, with respect to this Indenture, or for the appointment of
a receiver or trustee, or for any other remedy hereunder, unless:

          (a)  such Holder has previously given written notice to the Trustee of
               a continuing Event of Default with respect to the Securities of
               that series;

          (b)  the Holders of not less than 25% in principal amount of the
               Outstanding Securities of that series shall have made written
               request to the Trustee to institute proceedings in respect of
               such Event of Default in its own name as Trustee hereunder;

          (c)  such Holder or Holders have offered to the Trustee indemnity
               reasonably satisfactory to the Trustee against the costs,
               expenses and liabilities to be incurred in compliance with such
               request;

          (d)  the Trustee for 60 days after its receipt of such notice, request
               and offer of indemnity has failed to institute any such
               proceeding; and

                                     - 35 -
<PAGE>
 
          (e)  no direction inconsistent with such written request has been
               given to the Trustee during such 60-day period by the Holders of
               a majority in principal amount of the Outstanding Securities of
               that series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture or any Security to affect, disturb or prejudice the rights of
any other of such Holders, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all such Holders.

          SECTION 508.  UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL,
PREMIUM OR MAKE-WHOLE AMOUNT, IF ANY, INTEREST AND ADDITIONAL AMOUNTS.
Notwithstanding any other provision in this Indenture, the Holder of any
Security or coupon shall have the right which is absolute and unconditional to
receive payment of the principal of (and premium or Make-Whole Amount, if any)
and (subject to Sections 305 and 307) interest on, and any Additional Amounts in
respect of, such Security or payment of such coupon on the respective Stated
Maturity or Maturities specified in such Security or coupon (or, in the case of
redemption, on the Redemption Date or, in the case of repayment, on the
Repayment Date) and to institute suit for the enforcement of any such payment
and such rights shall not be impaired without the consent of such Holder.

          SECTION 509.  RESTORATION OF RIGHTS AND REMEDIES.  If the Trustee or
any Holder of a Security or coupon has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, the Issuer, the Trustee and the
Holders of Securities and coupons shall, subject to any determination in such
proceeding, be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

          SECTION 510.  RIGHTS AND REMEDIES CUMULATIVE.  Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities or coupons in the last paragraph of Section 306, no
right or remedy herein conferred upon or reserved to the Trustee or to each
Holder of Securities or coupons is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

          SECTION 511.  DELAY OR OMISSION NOT WAIVER.  No delay or omission of
the Trustee or of any Holder of any Security or coupon to exercise any right or
remedy accruing upon any Event of Default shall impair any such right or remedy
or constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to any
Holder may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by such Holder of Securities or coupons, as the
case may be.

          SECTION 512.  CONTROL BY HOLDERS OF SECURITIES.  The Holders of not
less than a majority in principal amount of the Outstanding Securities of any
series shall have the right to 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 the Securities of such series
and any related coupons, provided that

          (a)  such direction shall not be in conflict with any rule of law or
               with this Indenture or with the Securities of any series,

                                     - 36 -
<PAGE>
 
          (b)  the Trustee may take any other action deemed proper by the
               Trustee which is not inconsistent with such direction, and

          (c)  the Trustee need not take any action which might involve it in
               personal liability or be unduly prejudicial to the Holders of
               Securities of such series not joining therein.

          SECTION 513.  WAIVER OF PAST DEFAULTS.  The Holders of not less than
a majority in principal amount of the Outstanding Securities of any series may
on behalf of the Holders of all the Securities of such series and any related
coupons waive any past default hereunder with respect to such series and its
consequences, except a default

          (a)  in the payment of the principal of (or premium or Make-Whole
               Amount, if any) or interest on or Additional Amounts payable in
               respect of any Security of such series or any related coupons, or

          (b)  in respect of a covenant or provision hereof which under Article
               Nine cannot be modified or amended without the consent of the
               Holder of each Outstanding Security of such series affected.

          Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.

          SECTION 514.  WAIVER OF USURY, STAY OR EXTENSION LAWS.  The Issuer
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Issuer (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

          SECTION 515.  UNDERTAKING FOR COSTS.  All parties to this Indenture
agree, and each Holder of any Security by his acceptance thereof shall be deemed
to have agreed, that any court may in its discretion require, in any suit for
the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken or omitted by it as Trustee, the filing
by any party litigant in such suit of any undertaking to pay the costs of such
suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; but the provisions of this Section shall not apply to any
suit instituted by the Trustee, to any suit instituted by any Holder, or group
of Holders, holding in the aggregate more than 25% in principal amount of the
Outstanding Securities, or to any suit instituted by any Holder for the
enforcement of the payment of the principal of (or premium or Make-Whole Amount,
if any) or interest or Additional Amounts, if any on any Security on or after
the respective Stated Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date or, in the case of repayment, on or
after the Repayment Date).

                                  ARTICLE SIX

                                  THE TRUSTEE

          SECTION 601.  NOTICE OF DEFAULTS.  Within 90 days after the
occurrence of any default hereunder with respect to the Securities of any series
for which it is acting as trustee, the Trustee shall transmit in the manner and
to the extent provided in TIA Section 313(c), notice of such default hereunder
known to the Trustee, unless such default shall have been cured or waived;

                                     - 37 -
<PAGE>
 
provided, however, that, except in the case of a default in the payment of the
principal of (or premium or Make-Whole Amount, if any) or interest on or any
Additional Amounts with respect to any Security of such series, or in the
payment of any sinking fund installment with respect to the Securities of such
series, the Trustee shall be protected in withholding such notice if and so long
as Responsible Officers of the Trustee in good faith determine that the
withholding of such notice is in the best interests of the Holders of the
Securities and coupons of such series; and provided further that in the case of
any default or breach of the character specified in Section 501(d) with respect
to the Securities and coupons of such series, no such notice to Holders shall be
given until at least 60 days after the occurrence thereof.  For the purpose of
this Section, the term "default" means any event which is, or after notice or
lapse of time or both would become, an Event of Default with respect to the
Securities of such series.

          SECTION 602.  CERTAIN RIGHTS OF TRUSTEE.  Subject to the provisions
of TIA Section 315(a) through 315(d):

          (a)  the Trustee may rely and shall be protected in acting or
               refraining from acting upon any resolution, certificate,
               statement, instrument, opinion, report, notice, request,
               direction, consent, order, bond, debenture, note, coupon or other
               paper or document believed by it to be genuine and to have been
               signed or presented by the proper party or parties;

          (b)  any request or direction of the Issuer mentioned herein shall be
               sufficiently evidenced by an Issuer Request or Issuer Order
               (other than delivery of any Security, together with any coupons
               appertaining thereto, to the Trustee for authentication and
               delivery pursuant to Section 303 which shall be sufficiently
               evidenced as provided therein) and any resolution of the Board of
               Directors may be sufficiently evidenced by a Board Resolution;

          (c)  whenever in the administration of this Indenture the Trustee
               shall deem it desirable that a matter be proved or established
               prior to taking, suffering or omitting any action hereunder, the
               Trustee (unless other evidence be herein specifically prescribed)
               may, in the absence of bad faith on its part, rely upon an
               Officers' Certificate;

          (d)  the Trustee may consult with counsel and the written advice of
               such counsel or any Opinion of 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 reliance
               thereon;

          (e)  the Trustee shall be under no obligation to exercise any of the
               rights or powers vested in it by this Indenture at the request or
               direction of any of the Holders of Securities of any series or
               any related coupons pursuant to this Indenture, unless such
               Holders shall have offered to the Trustee security or indemnity
               reasonably satisfactory to the Trustee against the costs,
               expenses and liabilities which might be incurred by it in
               compliance with such request or direction;

          (f)  the Trustee shall not be bound to make any investigation into the
               facts or matters stated in any resolution, certificate,
               statement, instrument, opinion, report, notice, request,
               direction, consent, order, bond, debenture, note, coupon or other
               paper or document, but the Trustee, in its discretion, may make
               such further inquiry or investigation into such facts or matters
               as it may see fit, and, if the Trustee shall determine to make
               such further inquiry or investigation, it shall be entitled to
               examine the books, records and premises of the Issuer, personally
               or by agent or attorney following reasonable notice to the
               Issuer;

                                     - 38 -
<PAGE>
 
          (g)  the Trustee may execute any of the trusts or powers hereunder or
               perform any duties hereunder either directly or by or through
               agents or counsel and the Trustee shall not be responsible for
               any misconduct or negligence on the part of any agent or counsel
               appointed with due care by it hereunder; and

          (h)  subject to Sections 315(a) through 315(d) of the TIA, the Trustee
               shall not be charged with knowledge of any Event of Default
               described in Section 501(d), (e), (f), (g) or (h) hereof unless a
               Responsible Officer of the Trustee shall have actual knowledge of
               such Event of Default.

          The Trustee shall not be required to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

          Except during the continuance of an Event of Default, the Trustee
undertakes to perform only such duties as are specifically set forth in this
Indenture, and no implied covenants or obligations shall be read into this
Indenture against the Trustee.

          SECTION 603.  NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.
The recitals contained herein and in the Securities, except the Trustee's
certificate of authentication, and in any coupons shall be taken as the
statements of the Issuer, and neither the Trustee nor any Authenticating Agent
assumes any responsibility for their correctness.  The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder and that the statements made by it in a
Statement of Eligibility and Qualification on Form T-1 supplied to the Issuer
are true and correct, subject to the qualifications set forth therein.  Neither
the Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Issuer of Securities or the proceeds thereof.

          SECTION 604.  MAY HOLD SECURITIES.  The Trustee, any Paying Agent,
Security Registrar, Authenticating Agent or any other agent of the Trustee or
the Issuer, in its individual or any other capacity, may become the owner or
pledgee of Securities and coupons and, subject to TIA Sections 310(b) and 311 of
the TIA, may otherwise deal with the Issuer with the same rights it would have
if it were not Trustee, Paying Agent, Security Registrar, Authenticating Agent
or such other agent.

          SECTION 605.  MONEY HELD IN TRUST.  Except as provided in Section 402
and Section 1003, money held by the Trustee in trust hereunder need not be
segregated from other funds except to the extent required by law.  The Trustee
shall be under no liability for interest on any money received by it hereunder
except as otherwise agreed with the Issuer.

          SECTION 606.  COMPENSATION AND REIMBURSEMENT.  The Issuer agrees:

          (a)  to pay to the Trustee from time to time reasonable compensation
               for all services rendered by the Trustee hereunder (which
               compensation shall not be limited by any provision of law in
               regard to the compensation of a trustee of an express trust);

          (b)  except as otherwise expressly provided herein, to reimburse each
               of the Trustee and any predecessor Trustee upon its request for
               all reasonable expenses, disbursements and advances incurred or
               made by the Trustee in accordance with any provision of this
               Indenture (including the reasonable compensation and the expenses
               and disbursements of its agents and counsel), except any such
               expense, disbursement or advance as may be attributable to its
               negligence or bad faith; and

                                     - 39 -
<PAGE>
 
          (c)  to indemnify each of the Trustee and any predecessor Trustee for,
               and to hold it harmless against, any loss, liability or expense
               incurred without negligence or bad faith on its own part, arising
               out of or in connection with the acceptance or administration of
               the trust or trusts hereunder, including the costs and expenses
               of defending itself against any claim or liability in connection
               with the exercise or performance of any of its powers or duties
               hereunder.

          When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 501(f) or Section 501(g), the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

          As security for the performance of the obligations of the Issuer under
this Section, the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of (or premium or Make-Whole Amount, if
any) or interest or any Additional Amounts on particular Securities or any
related coupons.

          The provisions of this Section shall survive the termination of this
Indenture.

          SECTION 607.  CORPORATE TRUSTEE REQUIRED ELIGIBILITY; CONFLICTING
INTERESTS.  There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and shall have or be
wholly owned by an entity having a combined capital and surplus of at least
$50,000,000.  If such corporation publishes reports of condition at least
annually, pursuant to law or the requirements of Federal, state, territorial or
District of Columbia supervising or examining authority, then for the purposes
of this Section, the combined capital and surplus of such corporation shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published.  If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

          SECTION 608.  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

          (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 609.

          (b) The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Issuer. If any
instrument of acceptance by a successor Trustee shall not have been delivered to
the Trustee within 30 days after the giving of such notice of resignation, the
resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to such series.

          (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series delivered to the Trustee and to the
Issuer.

          (d)  If at any time:

               (1)  the Trustee shall fail to comply with the provisions of TIA
                    Section 310(b) after written request therefor by the Issuer
                    or by any Holder of a Security who has been a bona fide
                    Holder of a Security for at least six months, or

                                     - 40 -
<PAGE>
 
               (2)  the Trustee shall cease to be eligible under Section 607 and
                    shall fail to resign after written request therefor by the
                    Issuer or by any Holder of a Security who has been a bona
                    fide Holder of a Security for at least six months, or

               (3)  the Trustee shall become incapable of acting or shall be
                    adjudged a bankrupt or insolvent, or a receiver of the
                    Trustee or of its property shall be appointed or any public
                    officer shall take charge or control of the Trustee or of
                    its property or affairs for the purpose of rehabilitation,
                    conservation or liquidation,

then, in any such case, (A) the Issuer by or pursuant to a Board Resolution may
remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (B) subject to TIA Section 315(e), any Holder of a Security who
has been a bona fide Holder of a Security for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities of
such series and the appointment of a successor Trustee or Trustees.

          (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause with
respect to the Securities of one or more series, the Issuer, by or pursuant to a
Board Resolution, shall promptly appoint a successor Trustee or Trustees with
respect to the Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the Securities of one or
more or all of such series and that at any time there shall be only one Trustee
with respect to the Securities of any particular series) and shall comply with
the applicable requirements of Section 609. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Issuer and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of Section
609, become the successor Trustee with respect to the Securities of such series
and to that extent supersede the successor Trustee appointed by the Issuer. If
no successor Trustee with respect to the Securities of any series shall have
been so appointed by the Issuer or the Holders of Securities and accepted
appointment in the manner provided in Section 609, any Holder of a Security who
has been a bona fide Holder of a Security of such series for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee with
respect to Securities of such series.

          (f) The Issuer shall give notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each appointment
of a successor Trustee with respect to the Securities of any series in the
manner provided for notices to the Holders of Securities in Section 106. Each
notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.


          SECTION 609.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

          (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee shall execute,
acknowledge and deliver to the Issuer and to the retiring Trustee, an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; but, on request of the Issuer
or the successor Trustee, such retiring Trustee shall, upon, payment of its
charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee, and shall
duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder, subject nevertheless to its
claim, if any, provided for in Section 606.

                                     - 41 -
<PAGE>
 
          (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Issuer, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto,
pursuant to Article Nine hereof, wherein each successor Trustee shall accept
such appointment and which (1) shall contain such provisions as shall be
necessary or desirable to transfer and confirm to, and to vest in, each
successor Trustee all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the
appointment of such successor Trustee relates, (2) if the retiring Trustee is
not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustee's co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Issuer or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

          (c) Upon request of any such successor Trustee, the Issuer shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section, as the case may be.

          (d) No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

          SECTION 610.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS.  Any Corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any Corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
Corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such Corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto.  In case any Securities or coupons shall have
been authenticated, but not delivered, by the Trustee then in office, any
successor by merger, conversion or consolidation to such authenticating Trustee
may adopt such authentication and deliver the Securities or coupons so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities or coupons.  In case any Securities or coupons
shall not have been authenticated by  such predecessor Trustee, any such
successor Trustee may authenticate and deliver such Securities or coupons, in
either its own name or that of its predecessor Trustee, with the full force and
effect which this Indenture provides for the certificate of authentication of
the Trustee.

          SECTION 611.  APPOINTMENT OF AUTHENTICATING AGENT.  At any time when
any of the Securities remain Outstanding, the Trustee may appoint an
Authenticating Agent or Agents with respect to one or more series of Securities
which shall be authorized to act on behalf of the Trustee to authenticate
Securities of such series or pursuant to Section 306 issued upon original issue,
exchange, registration of transfer or partial redemption or repayment thereof,
and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder.  Any such appointment shall be evidenced by an
instrument in writing signed by a Responsible Officer of the Trustee, a copy 

                                     - 42 -
<PAGE>
 
of which instrument shall be promptly furnished to the Issuer. Wherever
reference is made in this Indenture to the authentication and delivery of
Securities by the Trustee or the Trustee's certification of authentication, such
reference shall be deemed to include authentication and delivery on behalf of
the Trustee by an Authenticating Agent and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent.

          Each Authenticating Agent shall be acceptable to the Issuer and shall
at all times be a bank or trust company or corporation organized and doing
business and in good standing under the laws of the United States of America or
of any State or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having or be wholly owned by an entity having a combined
capital and surplus of not less than $50,000,000 and subject to supervision or
examination by Federal or State authorities.  If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published.  In case at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

          Any Corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any Corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any Corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such Corporation shall be otherwise eligible
under this Section without the execution or filing of any paper or further act
on the part of the Trustee or the Authenticating Agent.

          An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Issuer.  The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Issuer.  Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Issuer and shall give
notice of such appointment to all Holders of Securities of the series with
respect to which such Authenticating Agent will serve in the manner set forth in
Section 106.  Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an
Authenticating Agent herein.  No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

          The Issuer agrees to pay to each Authenticating Agent from time to
time reasonable compensation including reimbursement of its reasonable expenses
for its services under this Section.

          If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have endorsed thereon, in
addition to or in lieu of the Trustee's certificate of authentication, an
alternate certificate of authentication substantially in the following form:

          This is one of the Securities of the series designated therein
referred to in the within-mentioned Indenture.

                              (TRUSTEE)
                              as Trustee

                              By:
                                 --------------------
                              as Authenticating Agent

                              By:
                                 --------------------
                              Authorized Signatory

          If all of the Securities of any series may not be originally issued at
one time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the Issuer
wishes to have Securities of such series authenticated upon original issuance,
the Trustee, if so requested in writing (which writing need not be accompanied
by or contained in an Officers' Certificate by the Issuer), shall appoint in
accordance with this Section an Authenticating Agent having an office in a Place
of Payment designated by the Issuer with respect to such series of Securities.

     Commission pursuant to Section 13 or Section 15(d) of the Exchange Act; or,

          SECTION 801.  CONSOLIDATIONS AND MERGERS OF ISSUER AND SALES, LEASES
AND CONVEYANCE PERMITTED SUBJECT TO CERTAIN CONDITIONS.  The Issuer may
consolidate with, or sell, lease or convey all or substantially all of its
assets to, or merge with or into, any other Corporation, provided that (a) the
Issuer shall be the continuing Corporation, or the successor Corporation or its
transferees or assignees of such assets (if other than the Issuer) formed by or
resulting from any such consolidation or merger or which shall have received the
transfer of such assets by lease (subject to the continuing obligations of
Issuer set forth in Section 802) or otherwise, either directly or indirectly,
shall expressly assume the payment of the principal of (and premium or Make-
Whole Amount, if any) and interest on all the Securities, and the

resulting from any such consolidation or merger or which shall have received the
transfer of assets pursuant to this Section 801 shall be a United States
Corporation; and (c) immediately after giving effect to such transaction and
treating any Debt which becomes an obligation of the Issuer or any Subsidiary as
a result thereof as having been incurred by the Issuer or such Subsidiary at the
time of such transaction, no Event of Default, and no event which, after notice
or the lapse of time, or both, would become such an Event of Default, shall have
occurred and be continuing.

          SECTION 802.  RIGHTS AND DUTIES OF SUCCESSOR CORPORATION.  In case of
any such consolidation, merger, sale, lease or conveyance and upon any such
assumption by the successor Corporation, such successor Corporation shall
succeed to and be substituted for the Issuer with the same effect as if it had
been named herein as the party of the first part, and the predecessor
Corporation, except in the event of a lease, shall be relieved of any further
obligation under this Indenture and the Securities.  Such successor Corporation
thereupon may cause to be signed, and may issue either in its own name or in the
name of the Issuer, any or all of the Securities issuable hereunder which
theretofore shall not have been signed by the Issuer and delivered to the
Trustee; and, upon the order of such successor Corporation, instead of the
Issuer, and subject to all the terms, conditions and limitations in this
Indenture prescribed, the Trustee shall authenticate and shall deliver any
Securities which previously shall have been signed and delivered by the officers
of the Issuer to the Trustee for authentication, and any Securities which such
successor Corporation thereafter shall cause to be signed and delivered to the
Trustee for that purpose.  All the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Securities had been issued at the date of the execution
hereof.

          In case of any such consolidation, merger, sale, lease or conveyance,
such changes in phraseology and form (but not in substance) may be made in the
Securities thereafter to be issued as may be appropriate.

          SECTION 803.  OFFICERS' CERTIFICATE AND OPINION OF COUNSEL.  Any
consolidation, merger, sale, lease or conveyance permitted under Section 801 is
also subject to the condition that the Trustee receive an Officers' Certificate
and an Opinion of Counsel to the effect that any such consolidation, merger,
sale, lease or conveyance, and the assumption by any successor Corporation,
complies with the provisions of this Article and that all conditions precedent
herein provided for relating to such transaction have been complied with.

     covenants are expressly being included solely for the benefit of such
     series) or to surrender any right or power herein conferred upon the

          (c) to add any additional Events of Default for the benefit of the
     Holders of all or any series of Securities (and if such Events of Default
     are to be for the benefit of less than all series of Securities, stating
     that such Events of Default are expressly being included solely for the
     benefit of such series); provided, however, that in respect of any such
     additional Events of Default such supplemental indenture may provide for a
     particular period of grace after default (which period may be shorter or
     longer than that allowed in the case of other defaults) or may provide for
     an immediate enforcement upon such default or may limit the remedies
     available to the Trustee upon such default or may limit the right of the
     Holders of a majority in aggregate principal amount of that or those series
     of Securities to which such additional Events of Default apply to waive
     such default; or

          (d) to add to or change any of the provisions of this Indenture to
     provide that Bearer Securities may be registrable as to principal, to
     change or eliminate any restrictions on the payment of principal of or any
     premium or interest on or any Additional Amounts with respect to Bearer
     Securities, to permit Bearer Securities to be issued in exchange for
     Registered Securities, to permit Bearer Securities to be issued in exchange
     for Bearer Securities of other authorized denominations or to permit or
     facilitate the issuance of Securities in uncertificated form, provided that
     any such action shall not adversely affect the interests of the Holders of
     Securities of any series or any related coupons in any material respect; or

          (e) to change or eliminate any of the provisions of this Indenture,
     provided that any such change or elimination shall become effective only
     when there is no Security Outstanding of any series created prior to the
     execution of such supplemental indenture which is entitled to the benefit
     of such provision; or

          (f) to secure the Securities; or

          (g) to establish the form or terms of Securities of any series and any
     related coupons as permitted by Sections 201 and 301; or

          (h) to evidence and provide for the acceptance of appointment
     hereunder by a successor Trustee with respect to the Securities of one or
     more series and to add to or change any of the provisions of this Indenture
     as shall be necessary to provide for or facilitate the administration of
     the trusts hereunder by more than one Trustee; or

          (i) to cure any ambiguity, to correct or supplement any provision
     herein which may be defective or inconsistent with any other provision
     herein, or to make any other provisions with respect to matters or
     questions arising under this Indenture which shall not be inconsistent with
     the provisions of this Indenture, provided such provisions shall not
     adversely affect the interests of the Holders of Securities of any series
     or any related coupons in any material respect;

          (j) to supplement any of the provisions of this Indenture to such
     extent as shall be necessary to permit or facilitate the defeasance and
     discharge of any series of Securities pursuant to Sections 401, 1402 and
     1403, provided that any such action shall not adversely affect the
     interests of the Holders of Securities of such series and any related
     coupons or any other series of Securities in any material respect; or

          (k) to add to or change any provisions of this Indenture to comply
     with any requirements of the Commission in connection with (i)
     qualification of the Indenture under the TIA and (ii) any registration of
     the Securities pursuant to the requirements of the Securities Act of 1933,
     as amended.


          SECTION 902.  SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.  With
the consent of the Holders of not less than a majority in principal amount of
all 

                                     - 47 -
<PAGE>
Outstanding Securities affected by such supplemental indenture, by Act of
said Holders delivered to the Issuer and the Trustee, the Issuer, when
authorized by or pursuant to a Board Resolution, and the Trustee may enter into
an indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders of
Securities and any related coupons under this Indenture; provided, however, that
no such supplemental indenture shall, without the consent of the Holder of each
Outstanding Security affected thereby:

          (a) change the Stated Maturity of the principal of (or premium or 
     Make-Whole Amount, if any, on) or any installment of principal of or
     interest on or any Additional Amounts with respect to, any Security, or
     reduce the principal amount thereof or the rate or amount of interest
     thereon or any Additional Amounts payable in respect thereof, or any
     premium payable upon the redemption thereof, or change any obligation of
     the Issuer to pay Additional Amounts pursuant to Section 1012 (except as
     contemplated by Section 801(a) and permitted by Section 901(a)), or reduce
     the amount of the principal of an Original Issue Discount Security that
     would be due and payable upon a declaration of acceleration of the Maturity
     thereof pursuant to Section 502 or the amount thereof provable in
     bankruptcy pursuant to Section 504, or adversely affect any right of
     repayment at the option of the Holder of any Security, or change any Place
     of Payment where, or the currency or currencies, currency unit or units or
     composite currency or currencies in which the principal of, any premium or
     interest on, or any Additional Amounts with respect to any Security is
     payable, or impair the right to institute suit for the enforcement of any
     such payment on or after the Stated Maturity thereof (or, in the case of
     redemption or repayment at the option of the Holder, on or after the
     Redemption Date or the Repayment Date, as the case may be), or

          (b) reduce the percentage in principal amount of the Outstanding
     Securities of any series, the consent of whose Holders is required for any
     such supplemental indenture, or the consent of whose Holders is required
     for any waiver with respect to such series (or compliance with certain
     provisions of this Indenture or certain defaults hereunder and their
     consequences) provided for in this Indenture, or reduce the requirements of
     Section 1504 for quorum or voting, or

          (c) modify any of the provisions of this Section, Section 513 or
     Section 1013, except to increase the required percentage to effect such
     action or to provide that certain other provisions of this Indenture cannot
     be modified or waived without the consent of the Holder of each Outstanding
     Security affected thereby.

          It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

          A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which has expressly been included solely for
the benefit of one or more particular series of Securities, or which modifies
the rights of the Holders of Securities of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

          SECTION 903.  EXECUTION OF SUPPLEMENTAL INDENTURES.  As a condition
to executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modification thereby of the trusts
created by this Indenture, the Trustee shall be entitled to receive, and
(subject to TIA Section 315) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this

Indenture.  The Trustee may, but shall not be obligated to, enter into any such
supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

          SECTION 904.  EFFECT OF SUPPLEMENTAL INDENTURES.  Upon the execution
of any supplemental indenture under this Article, this Indenture shall be
modified in accordance therewith, and such supplemental indenture shall form a
part of this Indenture for all purposes; and every Holder of Securities
theretofore or thereafter authenticated and delivered hereunder and of any
coupon appertaining thereto shall be bound thereby.

          SECTION 905.  CONFORMITY WITH TRUST INDENTURE ACT.  Every
supplemental indenture executed pursuant to this Article following the
qualification of the Indenture under the provisions of the TIA, shall conform to
the requirements of the TIA as then in effect.

          SECTION 906.  REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.
Securities of any series authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall, if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture.  If the Issuer shall so determine,
new Securities of any series so modified as to conform, in the opinion of the
Trustee and the Issuer, to any such supplemental indenture may be prepared and
executed by the Issuer and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.

          SECTION 907.  NOTICE OF SUPPLEMENTAL INDENTURES.  Promptly after the
execution by the Issuer and the Trustee of any supplemental indenture pursuant
to the provisions of Section 902, the Issuer shall give notice thereof to the
Holders of each Outstanding Security affected, in the manner provided for in
Section 106, setting forth in general terms the substance of such supplemental
indenture.

                                  ARTICLE TEN

                                   COVENANTS

          SECTION 1001.  PAYMENT OF PRINCIPAL, PREMIUM OR MAKE-WHOLE AMOUNT, IF
ANY, INTEREST AND ADDITIONAL AMOUNTS.  The Issuer covenants and agrees for the
benefit of the Holders of each series of Securities that it will duly and
punctually pay the principal of (and premium or Make-Whole Amount, if any) and
interest on and any Additional Amounts payable in respect of the Securities of
that series in accordance with the terms of such series of Securities, any
coupons appertaining thereto and this Indenture.  Unless otherwise specified as
contemplated by Section 301 with respect to any series of Securities, any
interest due on and any Additional Amounts payable in respect of any Bearer
Securities on or before Maturity, other than Additional Amounts, if any, payable
as provided in Section 1012 in respect of principal of (or premium or Make-Whole
Amount, if any, on) such a Security, shall be payable only upon presentation and
surrender of the several coupons for such interest installments as are evidenced
thereby as they severally mature. Unless otherwise specified with respect to
Securities of any series pursuant to Section 301, at the option of the Issuer,
all payments of principal may be paid by check to the registered Holder of the
Registered Security or other person entitled thereto against surrender of such
Security.

          SECTION 1002.  MAINTENANCE OF OFFICE OR AGENCY.  If Securities of a
series are issuable only as Registered Securities, the Issuer shall maintain in
each Place of Payment for any series of Securities an office or agency where
Securities of that series may be presented or surrendered for payment, where
Securities of that series may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Issuer in respect of the
Securities of that series and this Indenture may be served.  If Securities of a
series are issuable as Bearer Securities, the Issuer will maintain: (A) in the
Borough of Manhattan, New York City, an office or agency where any Securities of
that series may be presented or surrendered for payment, where any Securities of
that series may be surrendered for registration of transfer, where Securities of
that series may be surrendered for exchange, where notices and demands to or
upon the Issuer in respect of the Securities of that series and this Indenture
may be served and where Bearer Securities 

                                     - 49 -
<PAGE>
of that series and related coupons may be presented or surrendered for payment
in the circumstances described in the following paragraph (and not otherwise);
(B) subject to any laws or regulations applicable thereto in a Place of Payment
for that series which is located outside the United States, an office or agency
where Securities of that series and related coupons may be presented and
surrendered for payment (including payment of any Additional Amounts payable on
Securities of that series pursuant to Section 1012), provided, however, that if
the Securities of that series are listed on the Luxembourg Stock Exchange or any
other stock exchange located outside the United States and such stock exchange
shall so require, the Issuer will maintain a Paying Agent for the Securities of
that series in Luxembourg or any other required city located outside the United
States, as the case may be, so long as the Securities of that series are listed
on such exchange and (C) subject to any laws or regulations applicable thereto,
in a Place of Payment for that series located outside the United States an
office or agency where any Registered Securities of that series may be
surrendered for registration of transfer, where Securities of that series may be
surrendered for exchange and where notices and demands to or upon the Issuer in
respect of the Securities of that series and this Indenture may be served. The
Issuer will give prompt written notice to the Trustee of the location, and any
change in the location, of each such office or agency. If at any time the Issuer
shall fail to maintain any such required office or agency or shall fail to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, except that Bearer Securities of that series and the related coupons
may be presented and surrendered for payment (including payment of any
Additional Amounts payable on Bearer Securities of that series pursuant to
Section 1012) at the offices specified in the Security in Europe, and the Issuer
hereby appoints the same as its agent to receive such respective presentations,
surrenders, notices and demands, and the Issuer hereby appoints the Trustee its
agent to receive all such presentations, surrenders, notices and demands.

          Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium or interest on or Additional
Amounts in respect of Bearer Securities shall be made at any office or agency of
the Issuer in the United States or by check mailed to any address in the United
States or by transfer to an account maintained with a bank located in the United
States; provided, however, that, if amounts owing with respect to any Bearer
Securities of a series are payable in Dollars, payment of principal of and any
premium and interest on any Bearer Security (including any Additional Amounts
payable on Securities of such series pursuant to Section 1012) shall be made at
the office of the designated agent of the Issuer's Paying Agent in the Borough
of Manhattan, New York City, if (but only if) payment in Dollars of the full
amount of such principal, premium, interest or Additional Amounts, as the case
may be, at all offices or agencies outside the United States maintained for the
purpose by the Issuer in accordance with this Indenture, is illegal or
effectively precluded by exchange controls or other similar restrictions, as
evidenced by an Opinion of Counsel.

          The Issuer may from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all of such purposes, and may from time to time rescind
such designations, provided, however, that no such designations or rescission
shall in any manner relieve the Issuer of its obligation to maintain an office
or agency in accordance with the requirements set forth above for Securities of
any series for such purposes.  The Issuer will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location
of any such other office or agency.  Unless otherwise specified with respect to
any Securities pursuant to Section 301 with respect to a series of Securities,
the Issuer hereby designates as a Place of Payment for each series of Securities
the office or agency of the Issuer in the Borough of Manhattan, New York City,
and initially appoints the Trustee at its Corporate Trust Office as Paying Agent
in such city and as its agent to receive all such presentations, surrenders,
notices and demands.

          Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of the 

                                     - 50 -
<PAGE>
Indenture, then the Issuer will maintain with respect to each such series of
Securities, or as so required, at least one exchange rate agent.

          SECTION 1003.  MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.  If
the Issuer shall at any time act as its own Paying Agent with respect to any
series of any Securities and any related coupons, it will, on or before each due
date of the principal of (and premium or Make-Whole Amount, if any), or interest
on or Additional Amounts in respect of, any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum in the currency or currencies, currency unit or units or composite currency
or currencies in which the Securities of such series are payable (except as
otherwise specified pursuant to Section 301 for the Securities of such series)
sufficient to pay the principal (and premium or Make-Whole Amount, if any) or
interest or Additional Amounts so becoming due until such sums shall be paid to
such Persons or otherwise disposed of as herein provided, and will promptly
notify the Trustee of its action or failure so to act.

          Whenever the Issuer shall have one or more Paying Agents for any
series of Securities and any related coupons, it will, before each due date of
the principal of (and premium or Make-Whole Amount, if any), or interest on or
Additional Amounts in respect of, any Securities of that series, deposit with a
Paying Agent a sum (in the currency or currencies, currency unit or units or
composite currency or currencies described in the preceding paragraph)
sufficient to pay the principal (and premium or Make-Whole Amount, if any) or
interest or Additional Amounts, so becoming due, such sum to be held in trust
for the benefit of the Persons entitled to such principal, premium or interest
or Additional Amounts and (unless such Paying Agent is the Trustee) the Issuer
will promptly notify the Trustee of its action or failure so to act.

          The Issuer will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will:

(1)  hold all sums held by it for the payment of principal of (and premium or
     Make-Whole Amount, if any) or interest on Securities or Additional Amounts
     in trust for the benefit of the Persons entitled thereto until such sums
     shall be paid to such Persons or otherwise disposed of as herein provided;

(2)  give the Trustee notice of any default by the Issuer (or any other obligor
     upon the Securities) in the making of any such payment of principal (and
     premium or Make-Whole Amount, if any) or interest or Additional Amounts;
     and

(3)  at any time during the continuance of any such default upon the written
     request of the Trustee, forthwith pay

     to the Trustee all sums so held in trust by such Paying Agent.

          The Issuer may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Issuer Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Issuer or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Issuer or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such sums.

          Except as otherwise provided in the Securities of any series, any
money deposited with the Trustee or any Paying Agent, or then held by the
Issuer, in trust for the payment of the principal of (and premium or Make-Whole
Amount, if any) or interest on, or any Additional Amounts in respect of, any
Security of any series or any related coupon and remaining unclaimed for two
years after such principal (and premium or Make-Whole Amount, if any), interest
or Additional Amounts have become due and payable shall be paid to the Issuer
upon Issuer Request or (if then held by the Issuer) shall be discharged from
such trust; and the Holder of such Security shall thereafter, as an 

                                     - 51 -
<PAGE>
unsecured general creditor, look only to the Issuer for payment of such
principal of (and premium or Make-Whole Amount, if any) or interest on, or any
Additional Amounts in respect of, any Security, without interest thereon, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Issuer as trustee thereof, shall thereupon
cease, provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Issuer cause to
be published once, in an Authorized Newspaper, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such publication, any unclaimed balance of such money
then remaining will be repaid to the Issuer.

          SECTION 1004.  [INTENTIONALLY OMITTED].

          SECTION 1005.  [INTENTIONALLY OMITTED].

          SECTION 1006.  EXISTENCE.  Subject to Article Eight, the Issuer will
do or cause to be done all things necessary to preserve and keep in full force
and effect its existence, rights and franchises; provided, however, that the
Issuer shall not be required to preserve any right or franchise if the Board of
Directors shall determine that the preservation thereof is no longer desirable
in the conduct of the business of the Issuer and that the loss thereof is not
disadvantageous in any material respect to the Holders.

          SECTION 1007.  MAINTENANCE OF PROPERTIES.  The Issuer will cause all
of its material properties used or useful in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair
and working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the reasonable judgment of the Issuer may be necessary so
that the business carried on in connection therewith may be properly and
advantageously conducted at all times; provided, however, that the Issuer and
its Subsidiaries shall not be prevented from discontinuing the operation and
maintenance of any of such properties if such discontinuance is, in the judgment
of the Issuer, desirable in the conduct of its business and not disadvantageous
in any material respect to the Holders.

          SECTION 1008.  INSURANCE.  The Issuer will, and will cause each of
its Subsidiaries to, maintain insurance coverage by financially sound and
reputable insurance companies on all of its insurable property against loss or
damage with amounts and types of insurance that are commercially reasonable.

          SECTION 1009.  PAYMENT OF TAXES AND OTHER CLAIMS.  The Issuer will
pay or discharge or cause to be paid or discharged, before the same shall become
delinquent, (i) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or upon the income, profits or property of the
Issuer or any Subsidiary, and (ii) all lawful claims for labor, materials and
supplies which, if unpaid, might by law become a lien upon the property of the
Issuer or any Subsidiary; provided, however, that the Issuer shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings.

          SECTION 1010.  PROVISION OF FINANCIAL INFORMATION.   Whether or not
the Issuer is subject to Section 13 or 15(d) of the Exchange Act, and for so
long as any Securities are outstanding, the Issuer will, to the extent permitted
under the Exchange Act, file with the Commission the annual reports, quarterly
reports and other documents which the Issuer would have been required to file
with the Commission pursuant to such Section 13 or 15(d) (the "Financial
Statements") if the Issuer were so subject, such documents to be filed with the
Commission on or prior to the respective dates (the "Required Filing Dates") by
which the Issuer would have been required so to file such documents if the
Issuer were so subject.

                                     - 52 -
<PAGE>

          The Issuer will also in any event (x) within 15 days of each Required
Filing Date (i) transmit by mail to all Holders, as their names and addresses
appear in the Security Register, without cost to such Holders, copies of the
annual reports and quarterly reports which the Issuer would have been required
to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act
if the Issuer were subject to such Sections, and (ii) file with the Trustee
copies of the annual reports, quarterly reports and other documents which the
Issuer would have been required to file with the Commission pursuant to Section
13 or 15(d) of the Exchange Act if the Issuer were subject to such Sections, and
(y) if filing such documents by the Issuer with the Commission is not made under
the Exchange Act, promptly upon written request and payment of the reasonable
cost of duplication and delivery, supply copies of such documents to any
prospective Holder.

          SECTION 1011.  STATEMENT AS TO COMPLIANCE.  The Issuer shall deliver
to the Trustee, within 120 days after the end of each fiscal year (which is
currently December 31), a written statement (which need not be contained in or
accompanied by an Officers' Certificate) signed by the principal executive
officer, the principal financial officer or the principal accounting officer of
the Issuer, stating that:

(a)  a review of the activities of the Issuer during such year and of its
     performance under this Indenture has been made under his or her
     supervision, and
(b)  to the best of his or her knowledge, based on such review, (i) the Issuer
     has complied with all the conditions and covenants imposed on it under this
     Indenture throughout such year, or, if there has been a default in the
     fulfillment of any such condition or covenant, specifying each such default
     known to him or her and the nature and status thereof, and (ii) no event
     has occurred and is continuing which is, or after notice or lapse of time
     or both would become, an Event of Default, or, if such an event has
     occurred and is continuing, specifying each such event known to him and the
     nature and status thereof.

          SECTION 1012.  ADDITIONAL AMOUNTS.  If any Securities of a series
provide for the payment of Additional Amounts, the Issuer will pay to the Holder
of any Security of such series or any coupon appertaining thereto Additional
Amounts as may be specified as contemplated by Section 301.  Whenever in this
Indenture there is mentioned, in any context except in the case of Section
502(a), the payment of the principal of or any premium or interest on, or in
respect of, any Security of any series or payment of any related coupon or the
net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established pursuant to Section 301
to the extent that, in such context, Additional Amounts are, were or would be
payable in respect thereof pursuant to such terms and express mention of the
payment of Additional Amounts (if applicable) in any provisions hereof shall not
be construed as excluding Additional Amounts in those provisions hereof where
such express mention is not made.

          Except as otherwise specified as contemplated by Section 301, if the
Securities of a series provide for the payment of Additional Amounts, at least
10 days prior to the first Interest Payment Date with respect to that series of
Securities (or if the Securities of that series will not bear interest prior to
Maturity, the first day on which a payment of principal and any premium is
made), and at least 10 days prior to

each date of payment of principal and any premium or interest if there has been
any change with respect to the matters set forth in the below-mentioned
Officers' Certificate, the Issuer shall furnish to the Trustee and the Paying
Agent, if other than the Trustee, an Officers' Certificate instructing the
Trustee and such Paying Agent or Paying Agents whether such payment of principal
of and any premium or interest on the Securities of that series shall be made to
Holders of Securities of that series or any related coupons who are not United
States persons without withholding for or on account of any tax, assessment or
other governmental charge described in the Securities of the series.  If any
such withholding shall be required, then such Officers' Certificate shall
specify by country the amount, if any, required to be withheld on such payments
to such Holders of Securities of that series or related coupons and the Issuer
will pay to the Trustee or such Paying Agent the Additional Amounts required by
the terms of such Securities.  If the Trustee 

                                     - 53 -
<PAGE>
or any Paying Agent, as the case may be, shall not so receive the above-
mentioned certificate, then the Trustee or such Paying Agent shall be entitled
(i) to assume that no such withholding or deduction is required with respect to
any payment of principal or interest with respect to any Securities of a series
or related coupons until it shall have received a certificate advising otherwise
and (ii) to make all payments of principal and interest with respect to the
Securities of a series or related coupons without withholding or deductions
until otherwise advised. The Issuer covenants to indemnify the Trustee and any
Paying Agent for, and to hold them harmless against, any loss, liability or
expense reasonably incurred without negligence or bad faith on their part
arising out of or in connection with actions taken or omitted by any of them or
in reliance on any Officers' Certificate furnished pursuant to this Section or
in reliance on the Issuer's not furnishing such an Officers' Certificate.

          SECTION 1013.  WAIVER OF CERTAIN COVENANTS.  The Issuer may omit in
any particular instance to comply with any term, provision or condition set
forth in Sections 1004 to 1011, inclusive, if before or after the time for such
compliance the Holders of at least a majority in principal amount of all
Outstanding Securities of each series affected by such omission, by Act of such
Holders, either waive such compliance in such instance or generally waive
compliance with such covenant or condition, but no such waiver shall extend to
or affect such covenant or condition except to the extent so expressly waived,
and, until such waiver shall become effective, the obligations of the Issuer and
the duties of the Trustee in respect of any such term, provision or condition
shall remain in full force and effect.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

          SECTION 1101.  APPLICABILITY OF ARTICLE.  Securities of any series
which are redeemable before their Stated Maturity shall be redeemable in
accordance with their terms and (except as otherwise specified as contemplated
by Section 301 for Securities of any series) in accordance with this Article.

          SECTION 1102.  ELECTION TO REDEEM; NOTICE TO TRUSTEE.  The election
of the Issuer to redeem any Securities shall be evidenced by or pursuant to a
Board Resolution.  In case of any redemption at the election of the Issuer of
less than all of the Securities of any series, the Issuer shall, at least 45
days prior to the giving of notice of redemption in Section 1104 (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date and of the principal amount of Securities of such series to be
redeemed.  In the case of any redemption of Securities prior to the expiration
of any restriction on such redemption provided in the terms of such Securities
or elsewhere in this Indenture, the Issuer shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

          SECTION 1103.  SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.  If
less than all the Securities of any series issued on the same day with the same
terms are to be redeemed, the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee, from
the Outstanding Securities of such series issued on such date with the same
terms not previously called for redemption, by such method as the Trustee shall
deem fair and appropriate and which may provide for the selection for redemption
of portions (equal to the minimum authorized denomination for Securities of that
series or any integral multiple thereof) of the principal amount of Securities
of such series of a denomination larger than the minimum authorized denomination
for Securities of that series.

          The Trustee shall promptly notify the Issuer and the Security
Registrar (if other than itself) in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption,
the principal amount thereof to be redeemed.

                                     - 54 -
<PAGE>
          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

          SECTION 1104.  NOTICE OF REDEMPTION.  Notice of redemption shall be
given in the manner provided in Section 106, not less than 30 days nor more than
60 days prior to the Redemption Date, unless a shorter period is specified by
the terms of such series established pursuant to Section 301, to each Holder of
Securities to be redeemed.  Failure to give such notice in the manner herein
provided to the Holder of any Security designated for redemption as a whole or
in part, or any defect in the notice to any such Holder, shall not affect the
validity of the proceedings for the redemption of any other such Security or
portion thereof.  Any notice that is mailed to the Holders of Registered
Securities in the manner herein provided shall be conclusively presumed to have
been duly given, whether or not the Holder; receives the notice.

          All notices of redemption shall state:

(a)  the Redemption Date;

(b)  the Redemption Price, accrued interest to the Redemption Date payable as
     provided in Section 1106, if any, and Additional Amounts, if any,

(c)  if less than all Outstanding Securities of any series are to be redeemed,
     the identification (and, in the case of partial redemption, the principal
     amount) of the particular Security or Securities to be redeemed,

(d)  in case any Security is to be redeemed in part only, the notice which
     relates to such Security shall state that on and after the Redemption Date,
     upon surrender of such Security, the holder will receive, without a charge,
     a new Security or Securities of authorized denominations for the principal
     amount thereof remaining unredeemed,

(e)  that on the Redemption Date the Redemption Price and accrued interest to
     the Redemption Date payable as provided in Section 1106, if any, will
     become due and payable upon each such Security, or the portion thereof, to
     be redeemed and, if applicable, that interest thereon shall cease to accrue
     on and after said date,

(f)  the Place or Places of Payment where such Securities, together in the case
     of Bearer Securities with all coupons appertaining thereto, if any,
     maturing after the Redemption Date, are to be surrendered for payment of
     the Redemption Price and accrued interest, if any,

(g)  that the redemption is for a sinking fund, if such is the case,

(h)  that, unless otherwise specified in such notice, Bearer Securities of any
     series, if any, surrendered for redemption must be accompanied by all
     coupons maturing subsequent to the date fixed for redemption or the amount
     of any such missing coupon or coupons will be deducted from the Redemption
     Price, unless security or indemnity satisfactory to the Issuer, the Trustee
     for such series and any Paying Agent is furnished,

(i)  if Bearer Securities of any series are to be redeemed and any Registered
     Securities of such series are not to be redeemed, and if such Bearer
     Securities may be exchanged for Registered Securities not subject to 
     redemption on this

                                     - 55 -
<PAGE>
     Redemption Date pursuant to Section 305 or otherwise, the last date, as
     determined by the Issuer, on which such exchanges may be made,

(j)  the CUSIP number or the Euroclear or CEDEL reference numbers of such
     Security, if any (provided that the notice may contain a disclaimer as to
     the accuracy of such numbers), and

(k)  if applicable, that a Holder of Securities who desires to convert
     Securities for redemption must satisfy the requirements for conversion
     contained in such Securities, the then existing conversion price or rate,
     and the date and time when the option to convert shall expire.

          A notice of redemption published as contemplated by Section 106 need
not identify particular Registered Securities to be redeemed.

          Notice of redemption of Securities to be redeemed shall be given by
the Issuer or, at the Issuer's request, by the Trustee in the name and at the
expense of the Issuer.

          SECTION 1105.  DEPOSIT OF REDEMPTION PRICE.  At least one Business
Day prior to any Redemption Date, the Issuer shall deposit with the Trustee or
with a Paying Agent (or, if the Issuer is acting as its own Paying Agent, which
it may not do in the case of a sinking fund payment under Article Twelve,
segregate and hold in trust as provided in Section 1003) an amount of money in
the currency or currencies, currency unit or units or composite currency or
currencies in which the Securities of such series are payable (except as
otherwise specified pursuant to Section 301 for the Securities of such series)
sufficient to pay on the Redemption Date the Redemption Price of, and (except if
the Redemption Date shall be an Interest Payment Date) accrued interest on and
Additional Amounts with respect thereto, all the Securities or portions thereof
which are to be redeemed on that date.

          SECTION 1106.  SECURITIES PAYABLE ON REDEMPTION DATE.  Notice of
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified in the currency or currencies, currency unit or units or
composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) (together with accrued interest, if any, to the
Redemption Date), and from and after such date (unless the Issuer shall default
in the payment of the Redemption Price and accrued interest) such Securities
shall, if the same were interest-bearing, cease to bear interest and the coupons
for such interest appertaining to any Bearer

Securities so to be redeemed, except to the extent provided below, shall be
void.  Upon surrender of any such Security for redemption; in accordance with
said notice, together with all coupons, if any, appertaining thereto maturing
after the Redemption Date, such Security shall be paid by the Issuer at the
Redemption Price, together with accrued interest and Additional Amounts, if any,
to the Redemption Date; provided, however, that installments of interest on
Bearer Securities whose Stated Maturity is on or prior to the Redemption Date
shall be payable only at an office or agency located outside the United States
(except as otherwise provided in Section 1002) and, unless otherwise specified
as contemplated by Section 301, only upon presentation and surrender of coupons
for such interest; and provided further that, except as otherwise provided,
installments of interest on Registered Securities whose Stated Maturity is on or
prior to the Redemption Date shall be payable to the Holders of such Securities,
or one or more Predecessor Securities, registered as such at the close of
business on the relevant Record Dates according to their terms and the
provisions of Section 307.

          If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Issuer and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of

                                     - 56 -
<PAGE>
them and any Paying Agent harmless.  If thereafter the Holder of such Security
shall surrender to the Trustee or any Paying Agent any such missing coupon in
respect of which a deduction shall have been made from the Redemption Price,
such Holder shall be entitled to receive the amount so deducted; provided,
however, that interest represented by coupons shall be payable only upon
presentation and surrender of those coupons at an office or agency located
outside the United States (except as otherwise provided in Section 1002).

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium or Make-Whole
Amount, if any) shall, until paid, bear interest from the Redemption Date at the
rate borne by the Security.

          SECTION 1107.  SECURITIES REDEEMED IN PART.  Any Registered Security
which is to be redeemed only in part (pursuant to the provisions of this
Article) shall be surrendered at a Place of Payment therefor (with, if the
Issuer or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Issuer and the Trustee duly executed by,
the Holder thereof or his attorney duly authorized in writing) and the Issuer
shall execute and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge a new Registered Security or Securities of
the same series, of any authorized denomination as requested by such Holder in
aggregate principal amount equal to and in exchange for the unredeemed portion
of the principal of the Security so surrendered. If a Security in global form is
so surrendered, the Issuer shall execute, and the Trustee shall authenticate and
deliver to the depositary for such Security in global form as shall be specified
in the Issuer Order to the Trustee with respect thereto, without service charge,
a new Security in global form in a denomination equal to and in exchange for the
unredeemed portion of the principal of the Security in global form so
surrendered.

                                 ARTICLE TWELVE

                                 SINKING FUNDS

          SECTION 1201.  APPLICABILITY OF ARTICLE.  The provisions of this
Article shall be applicable to any sinking fund for the retirement of Securities
of a series except as otherwise specified as contemplated by Section 301 for
Securities of such series.

          The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment," and any payment in excess of such minimum amount provided for by
the terms of such Securities of any series is herein referred to as an "optional
sinking fund payment." If provided for by the terms of any Securities of any
series, the cash amount of any mandatory sinking fund payment may be subject to
reduction as provided in Section 1202.  Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series.

          SECTION 1202.  SATISFACTION OF SINKING FUND PAYMENT WITH SECURITIES.
The Issuer may, in satisfaction of all or any part of any mandatory sinking fund
payment with respect to the Securities of a series, (1) deliver Outstanding
Securities of such series (other than any Securities previously called for
redemption) together in the case of any Bearer Securities of such series with
all unmatured coupons appertaining thereto and (2) apply as a credit Securities
of such series which have been redeemed either at the election of the Issuer
pursuant to the terms of such Securities or through the application of permitted
optional sinking fund payments pursuant to the terms of such Securities, or
which have otherwise been acquired by the Issuer; provided that such Securities
so delivered or applied as a credit have not been previously so credited.  Such
Securities shall be received and credited for such purpose by the Trustee at the
applicable Redemption Price specified in such Securities for redemption through
operation of the sinking fund and the amount of such mandatory sinking fund
payment shall be reduced accordingly.

          SECTION 1203.  REDEMPTION OF SECURITIES FOR SINKING FUND.  Not less
than 60 days prior to each sinking fund payment date for Securities of any
series, the Issuer will 

                                     - 57 -
<PAGE>
deliver to the Trustee an Officers' Certificate specifying the amount of the
next ensuing mandatory sinking fund payment for that series pursuant to the
terms of that series, the portion thereof, if any, which is to be satisfied by
payment of cash in the currency or currencies, currency unit or units or
composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 1202, and the optional amount, if any, to be added in cash to the next
ensuing mandatory sinking fund payment, and will also deliver to the Trustee any
Securities to be so delivered and credited. If such Officers' Certificate shall
specify an optional amount to be added in cash to the next ensuing mandatory
sinking fund payment, the Issuer shall thereupon be obligated to pay the amount
therein specified. Not less than 30 days before each such sinking fund payment
date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 1103 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Issuer in the manner provided in Section 1104. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 1106 and 1107.

                                ARTICLE THIRTEEN

                       REPAYMENT AT THE OPTION OF HOLDERS

          SECTION 1301.  APPLICABILITY OF ARTICLE.  Repayment of Securities of
any  series before their Stated Maturity at the option of Holders thereof shall
be made in accordance with the terms of such Securities, if any, and (except as
otherwise specified by the terms of such series established pursuant to Section
301) in accordance with this Article.

          SECTION 1302.  REPAYMENT OF SECURITIES.  Securities of any series
subject to  repayment in whole or in part at the option of the Holders thereof
will, unless otherwise provided in the terms of such Securities, be repaid at a
price equal to the principal amount thereof, together with interest, if any,
thereon accrued to the Repayment Date specified in or pursuant to the terms of
such Securities.  The Issuer covenants that at least one Business Day prior to
the Repayment Date it will deposit with the Trustee or with a Paying Agent (or,
if the Issuer is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money in currency or currencies, currency
unit or units or composite currency or currencies in which the Securities of
such series are payable (except as otherwise specified pursuant to Section 301
for the Securities of such series) sufficient to pay the principal (or, if so
provided by the terms of the Securities of any series, a percentage of the
principal) of, and (except if the Repayment Date shall be an Interest Payment
Date) accrued interest on, all the Securities or portions thereof, as the case
may be, to be repaid on such date.


          SECTION 1303.  EXERCISE OF OPTION.  Securities of any series subject
to repayment  at the option of the Holders thereof will contain an "Option to
Elect Repayment" form on the reverse of such Securities.  In order for any
Security to be repaid at the option of the Holder, the Trustee must receive at
the Place of Payment therefor specified in the terms of such Security (or at
such other place or places of which the Issuer shall from time to time notify
the Holders of such Securities) not earlier than 60 days nor later than 30 days
prior to the Repayment Date (1) the Security so providing for such repayment
together with the "Option to Elect Repayment" form on  the reverse thereof duly
completed by the Holder (or by the Holder's attorney duly authorized in writing)
or (2) a telegram, telex, facsimile transmission or a letter from a member of a
national securities exchange, or the National Association of Securities Dealers,
Inc., or a commercial bank or trust company in the United States setting forth
the name of the Holder of the Security, the principal amount of the Security,
the principal amount of the Security to be repaid, the CUSIP number, if any, or
a description of the tenor and terms of the Security, a statement that the
option to elect repayment is being exercised thereby and a guarantee that the
Security to be repaid, together with the duly completed form entitled "Option to
Elect Repayment" on the reverse of the Security will be received by the Trustee
not later than the fifth Business Day after the date of such telegram, telex,

                                     - 58 -
<PAGE>
facsimile transmission or letter; provided, however, that such telegram, telex,
facsimile transmission or letter shall only be effective if such Security and
form duly completed are received by the Trustee by such fifth Business Day.  If
less than the entire principal amount of such Security is to be repaid in
accordance with the terms of such Security, the principal amount of such
Security to be repaid, in increments of the minimum denominations for Securities
of such  series, and the denomination or denominations of the Security or
Securities to be issued to the Holder for the portion of the principal amount of
such Security surrendered that is not to be repaid, must be specified.  The
principal amount of any Security providing for repayment at the option of the
Holder thereof may not be repaid in part if, following such repayment, the
unpaid principal amount of such Security would be less than the minimum
authorized denomination of Securities of the series of which such Security to be
repaid is a part.  Except as otherwise may be provided by the terms of any
Security providing for repayment at the option of the Holder thereof, exercise
of the repayment option by the Holder shall be irrevocable unless waived by the
Issuer.

          SECTION 1304.  WHEN SECURITIES PRESENTED FOR REPAYMENT BECOME DUE AND
PAYABLE.  If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Issuer on the Repayment Date therein specified,
and on and after such Repayment Date (unless the Issuer shall default in the
payment of such Securities on such Repayment Date) such Securities shall, if the
same were interest-bearing, cease to bear interest and the coupons for such
interest appertaining to any Bearer Securities so to be repaid, except to the
extent provided below, shall be void.  Upon surrender of any such Security for
repayment in accordance with such provisions, together with all coupons, if any,
appertaining thereto maturing after the Repayment Date, the principal amount of
such Security so to be repaid shall be paid by the Issuer, together with accrued
interest, if any, to the Repayment Date; provided, however, that coupons whose
Stated Maturity is on or prior to the Repayment Date shall be payable only at an
office or agency located outside the United States (except as otherwise provided
in Section 1002) and, unless otherwise specified pursuant to Section 301, only
upon presentation and surrender of such coupons; and provided further that, in
the case of Registered Securities, installments of interest, if any, whose
Stated Maturity is on or prior to the Repayment Date shall be payable (but
without interest thereon, unless the Issuer shall default in the payment
thereof) to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 307.

          If any Bearer Security surrendered for repayment shall not be
accompanied by all appurtenant coupons maturing after the Repayment Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1302 an amount equal to the face amount of all such missing
coupons, or the surrender of such missing coupon or coupons may be waived by the
Issuer and the Trustee if there be furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless.  If
thereafter the Holder of such Security shall surrender to the Trustee or any
Paying Agent any such missing coupon in respect of which a deduction shall have
been made as provided in the preceding sentence, such Holder shall be entitled
to receive the amount so deducted; provided, however, that interest represented
by coupons shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified as contemplated by Section 301, only upon presentation and
surrender of those coupons.

          If the principal amount of any Security surrendered for repayment
shall not be so repaid  upon surrender thereof, such principal amount (together
with interest, if any, thereon, accrued to such Repayment Date) shall, until
paid, bear interest from the Repayment Date at the rate of, interest or Yield to
Maturity (in the case of Original Issue Discount Securities) set forth in such
Security.

                                     - 59 -
<PAGE>
          SECTION 1305.  SECURITIES REPAID IN PART.  Upon surrender of any
Registered Security which is to be repaid in part only, the Issuer shall execute
and the Trustee shall authenticate and deliver to the Holder of such Security,
without service charge and at the expense of the Issuer, a new Registered
Security or Securities of the same series, of any authorized denomination
specified by the Holder, in an aggregate principal amount equal to and in
exchange for the portion of the principal of such Security so surrendered which
is not to be repaid.

                                ARTICLE FOURTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

          SECTION 1401.  APPLICABILITY OF ARTICLE; ISSUER'S OPTION TO EFFECT
DEFEASANCE OR COVENANT DEFEASANCE.  If, pursuant to Section 301, provision is
made for either or both of (a) defeasance of the Securities of or within a
series under Section 1402 or (b) covenant defeasance of the Securities of or
within a series under Section 1403, then the provisions of such Section or
Sections, as the case may be, together with the other provisions of this Article
(with such modifications thereto as may be specified pursuant to Section 301
with respect to any Securities), shall be applicable to such Securities and any
coupons appertaining thereto, and the Issuer may at its option by Board
Resolution, at any time, with respect to such Securities and any coupons
appertaining thereto, elect to have Section 1402 (if applicable) or Section 1403
(if applicable) be applied to such Outstanding Securities and any coupons
appertaining thereto upon compliance with the conditions set forth below in this
Article.

          SECTION 1402.  DEFEASANCE AND DISCHARGE.  Upon the Issuer's exercise
of the above option applicable to this Section with respect to any Securities of
or within a series, the Issuer shall be deemed to have been discharged from its
obligations with respect to such Outstanding Securities and any coupons
appertaining thereto on the date the conditions set forth in Section 1404 are
satisfied (hereinafter, "defeasance").  For this purpose, such defeasance means
that the Issuer shall be deemed to have paid and discharged the entire
indebtedness represented by such Outstanding Securities and any coupons
appertaining thereto, which shall thereafter be deemed to be "Outstanding" only
for the purposes of Section 1405 and the other Sections of this Indenture
referred to in clauses (A) and (B) below, and to have satisfied all of its other
obligations under such Securities and any coupons appertaining thereto and this
Indenture insofar as such Securities and any coupons appertaining thereto are
concerned (and the Trustee, at the expense of  the Issuer, shall execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of such Outstanding Securities and any coupons appertaining thereto
receive, solely from the trust  fund described in Section 1404 and as more fully
set forth in such Section, payments in respect of the principal of (and premium
or Make-Whole Amount, if any) and interest and Additional Amounts, if any, on
such  Securities and any coupons appertaining thereto when such payments are due
and any right of such Holder to exchange such Securities for other Securities,
(B) the Issuer's obligations with respect to such Securities under Sections 305,
306, 1002 and 1003 and with respect to the payment of Additional Amounts, if
any, on such Securities as contemplated by Section 1012 (but only to the extent
that the Additional Amounts payable with respect to such Securities exceed the
amount deposited in respect of such Additional Amounts pursuant to Section 1404
below), (C) the rights, powers, trusts, duties and immunities of the Trustee
hereunder and (D) this Article. Subject to compliance with this Article
Fourteen, the Issuer may exercise its option under this Section notwithstanding
the prior exercise of its option under Section 1403 with respect to such
Securities and any coupons appertaining thereto.

          SECTION 1403.  COVENANT DEFEASANCE.  Upon the Issuer's exercise of
the above option applicable to this Section with respect to any Securities of or
within a series, the Issuer shall be released from its obligations under
Sections 1004 to 1011, inclusive, and, if specified pursuant to Section 301, its
obligations under any other covenant, with respect to such Outstanding
Securities and any coupons appertaining thereto on and after the date the
conditions set forth in Section 1404 are satisfied (hereinafter, "covenant
defeasance"), and such Securities and any coupons 

                                     - 60 -
<PAGE>
appertaining thereto shall thereafter be deemed to be not "Outstanding" for the
purposes of any direction, waiver, consent or declaration or Act of Holders (and
the consequences of any thereof) in connection with any such covenant, but shall
continue to be deemed "Outstanding" for all other purposes hereunder. For this
purpose, such covenant defeasance means that, with respect to such Outstanding
Securities and any coupons appertaining thereto, the Issuer may omit to comply
with and shall have no liability in respect of any term, condition or limitation
set forth in any such Section or such other covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such Section or
such other covenant or by reason of reference in any such Section or such other
covenant to any other provision herein or in any other document and such
omission to comply shall not constitute a default or an Event of Default under
Section 501(d) or 501(h) or otherwise, as the case may be, but, except as
specified above, the remainder of this Indenture and such Securities and any
coupons appertaining thereto shall be unaffected thereby.

          SECTION 1404.  CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.  The
following shall be the conditions to application of Section 1402 or Section 1403
to any Outstanding Securities of or within a series and any coupons appertaining
thereto:

(a)  The Issuer shall irrevocably have deposited or caused to be deposited with
     the Trustee (or another trustee satisfying the requirements of Section 607

     an Opinion of Counsel, each stating that all conditions precedent to the
     defeasance under Section 1402 or the covenant defeasance under Section 1403

     Issuer in connection therewith pursuant to Section 301.

          SECTION 1405.  DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD
IN TRUST; OTHER MISCELLANEOUS PROVISIONS.  Subject to the provisions of the
last paragraph of Section 1003, all money and Government Obligations (or other
property as may be provided pursuant to Section 301) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively
for purposes of this Section 1405, the "Trustee") pursuant to Section 1404 in

premium or Make-Whole Amount, if any) and interest and Additional Amounts, if
any, but such money need not be segregated from other funds except to the extent
required by law.

Section 301, in or pursuant to this Indenture or any Security if, after a
deposit referred to in Section 1404(a) has been made, (a) the Holder of a
Security in respect of which such deposit was made is entitled to, and does,
elect pursuant to Section 301 or the terms of such Security to receive payment
in a currency or currency unit other than that in which the deposit pursuant to
Section 1404(a) has been made in respect of such Security, or (b) a Conversion
Event occurs in respect of the Foreign Currency in which the deposit pursuant to
Section 1404(a) has been made, the indebtedness represented by such Security and
any coupons appertaining thereto shall be deemed to have been, and will be,
fully discharged and satisfied through the payment of the principal of (and
premium or Make-Whole Amount, if any), and interest, if any, on and Additional
Amounts, if any, with respect to such Security as the same becomes due out of
the proceeds yielded by converting (from time to time as specified below in the
case of any such election) the amount or other property deposited in respect of
such Security into the currency or currency unit in which such Security becomes
payable as a result of such election or Conversion Event based on the applicable
market exchange rate for such currency or currency unit in effect on the second
Business Day prior to each payment date, except, with respect to a Conversion
Event, for such Foreign Currency in effect (as nearly as feasible) at the time
of the Conversion Event.

          The Issuer shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the Government Obligations deposit
pursuant to Section 1404 or the principal and interest received in respect
thereof other than any such tax, fee or other charge which 

                                     - 62 -
<PAGE>
by law is for the account of the Holders of such Outstanding Securities and any
coupons appertaining thereto.

          Anything in this Article to the contrary notwithstanding, subject to
Section 606, the Trustee shall deliver or pay to the Issuer from time to time
upon Issuer Request any money or Government Obligations (or other property and
any proceeds therefrom) held by it as provided in Section 1404 which, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect a defeasance or covenant defeasance, as applicable, in accordance with
this Article.

     of such series and of the appointment of proxies and in regard to the
     appointment and duties of inspectors of votes, the submission and
     examination of proxies, certificates and other evidence of the right to

     Person executing the proxy witnessed or guaranteed by any trust company,
     bank or banker authorized by Section 104 to certify to the holding of
     Bearer Securities.  Such regulations may provide that written instruments

     genuine without the proof specified in Section 104 or other proof.

(b)  The Trustee shall, by an instrument in writing appoint a temporary chairman
     of the meeting, unless the meeting shall have been canceled by the Issuer
     or by Holders of Securities as provided in Section 1502(b), in which case
     the Issuer or the Holders of Securities of the series calling the meeting,
     as the case may be, shall in like manner appoint a temporary chairman.  A

     entitled to one vote for each $1,000 principal amount of the Outstanding
     Securities of such series held or represented by him; provided, however
     that no vote shall be cast or counted at any meeting in respect of any
     Security challenged as not Outstanding and ruled by the chairman of the
     meeting to be not Outstanding.  The chairman of the meeting shall have no
     right to vote, except as a Holder of a Security of such series or proxy.

(d)  Any meeting of Holders of Securities of any series duly called pursuant to
     Section 1502 at which a quorum is present may be adjourned from time to
     time by Persons entitled to vote a majority in principal amount of the
     Outstanding Securities of such series represented at the meeting, and the
     meeting may be held as so adjourned without further notice.

vote upon any resolution submitted to any meeting of Holders of Securities of
any series shall be by written ballots on which shall be subscribed the
signatures of the Holders of Securities of such series or of their
representatives by proxy and the principal amounts and serial numbers of the
Outstanding Securities of such series held or represented by them.  The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting.  A record, at least in
duplicate, of the proceedings of each meeting of Holders of Securities of any
Series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the fact, setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1502 and, if
applicable, Section 1504.  Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Issuer and another to the Trustee to be preserved
by the Trustee, the latter to have attached thereto the ballots voted at the
meeting.  Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

          SECTION 1507.  EVIDENCE OF ACTION TAKEN BY HOLDERS.  Any request,
demand, authorization, direction, notice consent, waiver or other action
provided by this Indenture to be given or taken by a specified percentage in
principal amount of the Holders of any or all series may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such specified percentage of Holders in person or by agent duly appointed in
writing, and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the
Trustee.  Proof and execution of any instrument or of a writing appointing any
such agent shall be sufficient for any purpose of this Indenture and (subject to
Article Six) conclusive in favor of the Trustee and the Issuer, if made in the
manner provided in this Article.

          SECTION 1508.  PROOF OF EXECUTION OF INSTRUMENTS.  Subject to Article
Six, the execution of any instrument by a Holder or his agent or proxy may be
proved in

Securities of any series in which not all of such Securities are denominated in
the same currency, or (b) any distribution to Holders of Securities, in the
absence of any provision to the contrary in the form of Security of any
particular series or pursuant to this Indenture or the Securities, any amount in
respect of any Security denominated in a currency other than Dollars shall be
treated for any such action or distribution as that amount of Dollars that could
be obtained for such amount on such reasonable basis of exchange and as of the
record date with respect to Registered Securities of such series (if any) for
such action, determination of rights for distribution (or, if there shall be no
applicable record date, such other date reasonably proximate to the date of such
action, determination of rights or distribution) as the Issuer may specify in a
written notice to the Trustee or, in the absence of such written notice, as the
Trustee may determine.

from time to time as set forth in the prospectus which forms a part of the
Registration Statement (the "Prospectus"), and as to be set forth in one or
more supplements to the Prospectus (each, a "Prospectus Supplement"). This
opinion letter is furnished to you at your request to enable you to fulfill
the requirements of Item 601(b)(5) of Regulation S-K, 17 C.F.R. ss.
229.601(b)(5), in connection with the Registration Statement.
 
  As counsel to the Company, we have examined the Company's Articles of
Incorporation, as amended (the "Articles"), and such Company records,
certificates and other documents and relevant statutes, regulations, published
rulings and such questions of law as we considered necessary or appropriate
for the purpose of this opinion.
 
  In our examination, we have assumed the authenticity of original documents,
the accuracy of copies and the genuineness of signatures. We have relied upon
the representations and statements of officers and other representatives of
the Company with respect to the factual determinations underlying the legal
conclusions set forth herein. We have not attempted to verify independently
such representations and statements.
 
  We assume that the issuance, sale, amount and terms of the Securities to be
offered from time to time will be duly authorized and determined by proper
action of the Board of Directors of the Company consistent with the procedures
and terms described in the Registration Statement (each, a "Board Action") and
in accordance with the Articles and applicable Maryland law. We further assume
that (i) any Debt Securities will be issued pursuant to one or more indentures
(each, an "Indenture"), the forms of which will be filed as exhibits to a
Current Report on Form 8-K prior to issuance thereof, (ii) any Warrants will
be issued under one or more warrant agreements (each, a "Warrant Agreement"),
each to be between the Company and a warrant agent identified therein (each, a
"Warrant Agent"), and (iii) prior to any issuance of shares of Preferred
Stock, appropriate articles supplementary shall be filed for recordation with
the State Department of Assessments and Taxation of the State of Maryland
(each, "Articles Supplementary").
 
  This opinion letter is based as to matters of law solely on (i) the General
Corporation Law of the State of Maryland and (ii) Maryland contract law (but
not including any statutes, ordinances, administrative decisions, rules or
regulations of any political subdivision of Maryland), in each case as
currently in effect, and we express no opinion herein as to any other laws,
statutes, ordinances, rules or regulations.

  Based upon, subject to and limited by the foregoing and the other
qualifications herein, we are of the opinion that:
 
    1. When the Registration Statement has become effective under the
  Securities Act of 1933, as amended (the "Act"), and when the Debt
  Securities have been (a) duly established by an Indenture or any
  supplemental indenture thereto, (b) duly authorized and established by
  applicable Board Action and duly authenticated by the Trustee thereunder
  (the "Trustee"), and (c) duly executed and delivered on behalf of the
  Company against payment therefor in accordance with the terms of such Board
  Action, any applicable underwriting agreement, an Indenture and any
  applicable supplemental indenture, and as contemplated by the Registration
  Statement and/or the applicable Prospectus Supplement, the Debt Securities
  will constitute binding obligations of the Company, enforceable in
  accordance with their terms, except as may be limited by bankruptcy,
  insolvency, reorganization, moratorium or other laws affecting rights of
  creditors and other obligees (including, without limitation, the effect of
  statutory and other law regarding fraudulent conveyances, fraudulent
  transfers and preferential transfers) and as may be limited by the exercise
  of judicial discretion and the application of principles of equity,
  including, without limitation, requirements of good faith, fair dealing,
  conscionability and materiality (regardless of whether the Debt Securities
  are considered in a proceeding in equity or at law).
 
    2. When the Registration Statement has become effective under the Act and
  when a series of the Preferred Stock has been duly authorized and
  established by applicable Board Action, in accordance with the terms of the
  Articles and applicable law, and appropriate Articles Supplementary have
  been duly filed, and, upon issuance and delivery of such series of
  Preferred Stock against payment of valid consideration therefor in
  accordance with the terms of such Board Action and any applicable
  underwriting or purchase agreement, and as contemplated by the Registration
  Statement and/or the applicable Prospectus Supplement, the shares
  represented by such series of Preferred Stock will be validly issued, fully
  paid and nonassessable.
 
    3. When the Registration Statement has become effective under the Act,
  upon due authorization by Board Action of an issuance of Common Stock, and
  upon issuance and delivery of such Common Stock against payment of valid
  consideration therefor in accordance with the terms of such Board Action
  and any applicable underwriting or purchase agreement, and as contemplated
  by the Registration Statement and/or the applicable Prospectus Supplement,
  such shares of Common Stock will be validly issued, fully paid and
  nonassessable.
 
    4. When the Registration Statement has become effective under the Act and
  when the Warrants have been (a) duly established pursuant to the related
  Warrant Agreement, (b) duly authorized and established by applicable Board
  Action and duly authenticated by the Warrant Agent, and (c) duly executed
  and delivered on behalf of the Company against payment therefor in
  accordance with the terms of such Board Action, any applicable underwriting
  or purchase agreement and the applicable Warrant Agreement and as
  contemplated by the Registration Statement and/or the applicable Prospectus
  Supplement, the Warrants will constitute binding obligations of the
  Company, enforceable in accordance with their terms, except as may be
  limited by bankruptcy, insolvency, reorganization, moratorium or other laws
  affecting rights of creditors and other obligees (including, without
  limitation, the effect of statutory and other law regarding fraudulent
  conveyances, fraudulent transfers and preferential transfers) and as may be
  limited by the exercise of judicial discretion and the application of
  principles of equity, including, without limitation, requirements of good
  faith, fair dealing, conscionability and materiality (regardless of whether
  the Warrants are considered in a proceeding in equity or at law).
 
  The opinions expressed in Paragraphs (1) and (4) above shall be understood
to mean only that if there is a default in performance of an obligation, (i)
if a failure to pay or other damage can be shown and (ii) if the defaulting
party can be brought into a court which will hear the case and apply the
governing law, then, subject to the availability of defenses and to the
exceptions set forth in Paragraphs (1) and (4), the court will provide a money
damage (or perhaps injunctive or specific performance) remedy.
 
  To the extent that the obligations of the Company under an Indenture may be
dependent upon such matters, we assume for purposes of this opinion that the
Trustee is duly organized, validly existing and in good standing
 
                                       2

under the laws of its jurisdiction of organization; that the Trustee is duly
qualified to engage in the activities contemplated by the Indenture; that the
Indenture has been duly authorized, executed and delivered by the Trustee and
constitutes the legally valid and binding obligation of the Trustee
enforceable against the Trustee in accordance with its terms; that the Trustee
is in compliance, with respect to acting as a trustee under the Indenture,
with all applicable laws and regulations; and that the Trustee has the
requisite organizational and legal power and authority to perform its
obligations under the Indenture.
 
  To the extent that the obligations of the Company under any Warrant
Agreement may be dependent upon such matters, we assume for purposes of this
opinion that the applicable Warrant Agent is duly organized, validly existing
and in good standing under the laws of its jurisdiction of organization; that
the Warrant Agent is duly qualified to engage in the activities contemplated
by the Warrant Agreement; that the Warrant Agreement has been duly authorized,
executed and delivered by the Warrant Agent and constitutes the legally valid
and binding obligation of the Warrant Agent enforceable against the Warrant
Agent in accordance with its terms; that the Warrant Agent is in compliance,
with respect to acting as a warrant agent under the Warrant Agreement, with
all applicable laws and regulations; and that the Warrant Agent has the
requisite organizational and legal power and authority to perform its
obligations under the Warrant Agreement.
 
  We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to all references to our firm in the Registration
Statement. In giving this consent, we do not admit that we come within the
category of persons whose consent is required under Section 7 of the Act or
the rules promulgated thereunder.
 
  This opinion is rendered solely for your benefit in connection with the
transactions described above upon the understanding that we are not hereby
assuming any professional responsibility to any other person. Except as
provided in the preceding paragraph, this opinion may not be relied upon by
any other person and this opinion may not be used, disclosed, quoted, filed
