<PAGE>
                                  THE COMPANY

     The Company is a fully integrated, self-administered and self-managed
publicly traded real estate investment trust (a 'REIT') that focuses primarily
on the acquisition, development, ownership and operation of office properties in
select suburban markets across the United States.

     The Company's principal executive offices are located at 1700 Pennsylvania
Avenue, N.W., Washington, D.C. 20006, and its telephone number is (202)
624-7500. The Company was organized as a Maryland corporation on July 9, 1992.

       

                                  RISK FACTORS

     Prospective investors should carefully consider, among other factors, the
matters described below.

REAL ESTATE INVESTMENT RISKS

     General. Investments in real property are subject to varying degrees of
risk. The yields available from equity investments in real estate and the
Company's ability to service debt will depend in large part on the amount of
income generated, expenses incurred and capital expenditures required by its
real property investments. The Company's income from office properties may be
adversely affected by a number of factors, including the general economic
climate and local real estate conditions, an over-supply of, or a reduction in
demand for, office space in the areas where its properties are located and the
attractiveness of the properties to tenants. Income from properties and real
estate values also are affected by such factors as the cost of compliance with
government regulation, including zoning and tax laws and the potential for
liability under applicable laws. Certain significant expenditures associated
with each equity investment by the Company in a property (such as operating
expenses and capital expenditures costs) may not be reduced when circumstances
cause a reduction in income from the property.

     Renewal of Leases and Reletting of Space. The Company is subject to the
risks that upon expiration of leases for space located at its properties, the
space may not be relet or, if relet, the terms of the renewal or reletting
(including the cost of required renovations or concessions to tenants) may be
less favorable than current lease terms. Although the Company has established an
annual budget for renovation and reletting costs that it believes is reasonable
in light of each property's situation, no assurance can be given that this
budget will be sufficient to cover these costs. If the Company is unable
promptly to relet or renew leases for all or substantially all of the space at
its properties, if the rental rates upon such renewal or reletting are
significantly lower than expected, or if the Company's reserves for these
purposes prove inadequate, then the Company's cash provided by operating
activities and ability to make expected distributions to stockholders or debt
service payments may be adversely affected.

     Possible Environmental Liabilities. Under various federal, state and local
laws, ordinances and regulations, a current or previous owner or operator of
real estate may be required to investigate and clean up certain hazardous
substances released at the property, and may be held liable to a governmental
entity or to third parties for property damage and for investigation and cleanup
costs incurred by such parties in connection with the contamination. In
addition, some environmental laws create a lien on the contaminated site in
favor of the government for damages and costs it incurs in connection with the
contamination. The presence of contamination or the failure to remediate
contamination may adversely affect the owner's ability to sell or lease real
estate or to borrow using the real estate as collateral. The owner or operator
of a site may be liable under common law to third parties for damages and
injuries resulting from environmental contamination emanating from the site. The
Company has not been notified by any governmental authority of any material
non-compliance, liability or other claim in connection with any of its
properties, and the Company is not aware of any other material environmental
condition with respect to any of its properties. No assurance, however, can be
given that no prior owner created any material environmental condition not known
to the Company, that no material environmental condition with respect to any
property has occurred during the Company's ownership thereof, or that future
uses or conditions (including, without limitation, changes in applicable
environmental laws and regulations) will not result in imposition of
environmental liability against the Company.

                                       2
<PAGE>
REAL ESTATE FINANCING RISKS

     Debt Financing. The Company is subject to the risks associated with debt
financing, including the risk that the cash provided by the Company's operating
activities will be insufficient to meet required payments of principal and
interest, the risk of rising interest rates on the Company's floating rate debt
that is not hedged, the risk that the Company will not be able to repay or
refinance existing indebtedness (which generally will not have been fully
amortized at maturity) or that the terms of such refinancing will not be as
favorable as the terms of existing indebtedness. In the event the Company is
unable to secure refinancing of such indebtedness on acceptable terms, the
Company might be forced to dispose of properties upon disadvantageous terms,
which might result in losses to the Company, or to obtain financing at
unfavorable terms, either of which might adversely affect the cash flow
available for distribution to stockholders or meet debt service obligations. In
addition, if a property or properties are mortgaged to secure payment of
indebtedness and the Company is unable to meet required mortgage payments, the
mortgage securing the property could be foreclosed upon by, or the property
could be otherwise transferred to, the mortgagee with a consequent loss of
income and asset value to the Company.

     Degree of Leverage. At February 28, 1998, on a consolidated basis, the
Company's total indebtedness was approximately $1.188 billion and the ratio of
its total indebtedness to total assets (excluding intangibles) was 38.8%. The
degree to which the Company is leveraged could have important consequences to
holders of the Securities, including affecting the Company's ability to obtain
additional financing in the future for working capital, capital expenditures,
acquisitions, development or other general corporate purposes and making the
Company more vulnerable to a downturn in its business or the economy generally.

ACQUISITION AND DEVELOPMENT RISKS

     The Company intends to continue acquiring and developing office properties
in markets where it believes that such acquisition or development is consistent
with the business strategies of the Company. Acquisitions entail risks that
investments will fail to perform in accordance with expectations and that
judgments with respect to the costs of improvements to bring an acquired
property up to standards established for the market position intended for that
property will prove inaccurate, as well as general investment risks associated
with any new real estate investment. See '--Real Estate Investment Risks' above.
New office development also is subject to a number of risks, including, but not
limited to, construction delays or cost overruns that may increase project
costs, financing risks as described above, the failure to meet anticipated
occupancy or rent levels, failure to receive required zoning, occupancy and
other governmental permits and authorizations and changes in applicable zoning
and land use laws, which may result in the incurrence of development costs in
connection with projects that are not pursued to completion. In addition,
because the Company must distribute 95% of its taxable income in order to
maintain its qualification as a REIT, the Company anticipates that new
acquisitions and developments will be financed primarily through periodic equity
and debt offerings, lines of credit or other forms of secured or unsecured
financing. If permanent debt or equity financing is not available on acceptable
terms, further acquisitions or development activities may be curtailed or cash
available for distribution to stockholders or to meet debt service obligations
may be adversely affected.

CHANGE IN BUSINESS STRATEGY; RISKS ASSOCIATED WITH THE ACQUISITION OF
SUBSTANTIAL NEW PROPERTIES

     In November 1995, the Company shifted its emphasis from downtown
Washington, D.C. properties toward a more national business strategy, focusing
primarily on office properties in suburban growth markets across the United
States. This change represented a significant shift in the business strategy of
the Company. Although the Company's Board of Directors (the 'Board') believes
that such a shift in strategy was warranted in light of the opportunities
available to the Company, there is no assurance that the Company's efforts to
implement its national business strategy will continue to be successful.
Consistent with the Company's strategy of acquiring office properties in
suburban growth markets, the Company has significantly expanded its portfolio of
office properties since November 1995. These

                                       3
<PAGE>
properties have a relatively short operating history under the Company's
management and they may have characteristics or deficiencies unknown to the
Company affecting their valuation or revenue potential.

SUBSTANTIAL OWNERSHIP OF COMMON STOCK

     As of April 13, 1998, Security Capital Holdings S.A., a wholly owned
subsidiary of Security Capital U.S. Realty (together with Security Capital U.S.
Realty, 'SC-USREALTY'), owned approximately 40.0% of the outstanding shares of
the Company's Common Stock (36.2% of the Common Stock on a fully diluted basis),
and SC-USREALTY has the right to nominate a proportionate number of the
directors of the Board based upon its ownership of stock on a fully-diluted
basis, rounded down to the nearest whole number (but in no event more than 40%
of the directors). As a result, SC-USREALTY is the largest single stockholder of
the Company, while no other stockholder is permitted to own more than 5% of the
Company's Common Stock, subject to certain exceptions set forth in the Articles
of Incorporation or approved by the Board. Although certain standstill
provisions preclude SC-USREALTY from increasing its percentage interest in the
Company above 45% until at least April 30, 2001 (subject to certain exceptions)
and the Articles of Incorporation preclude it from increasing such percentage
interest thereafter, and SC-USREALTY agreed to certain limitations on its voting
rights with respect to its shares of Common Stock, SC-USREALTY nonetheless has a
substantial influence over the affairs of the Company. This concentration of
ownership in one stockholder could potentially be disadvantageous to other
stockholders' interests. In addition, so long as SC-USREALTY owns at least 25%
of the outstanding Common Stock of the Company on a fully diluted basis,
SC-USREALTY will be entitled (except in certain limited circumstances), upon
compliance with certain specified conditions, to a participation right to
purchase or subscribe for, either as part of such issuance or in a concurrent
issuance, a total number of shares of Common Stock or Preferred Stock, as the
case may be, equal to up to 30% (or 35% in certain circumstances) of the total
number of shares or of Common Stock or Preferred Stock, as applicable, proposed
to be issued by the Company.

LIMITATIONS ON CORPORATE ACTIONS

     In conjunction with the transaction in which SC-USREALTY acquired its
initial interest in the Company (the 'SC-USREALTY Transaction'), the Company
agreed to certain limitations on its operations, including restrictions relating
to incurrence of additional indebtedness, retention of third-party managers for
the Company's properties, investments in properties other than office buildings,
issuances of limited partnership interests ('CRLP Units') of Carr Realty, L.P.,
a partnership that owns certain of the Company's properties, and certain other
matters. The Company may take actions relating to these matters only with the
consent of SC-USREALTY. In addition, the Company is contractually obligated to
abide by certain limitations on the amount of assets that it owns indirectly
through other entities and the manner in which it conducts its business
(including the types of assets that it can acquire and own and the manner in
which such assets are operated). The Company also is obligated to use reasonable
efforts to effect all dispositions of assets in transactions that are tax-free
exchanges and do not generate 'capital gain dividends' to stockholders of the
Company. These limitations (which generally were designed to address special
U.S. tax considerations applicable to foreign corporations such as SC-USREALTY
under the Internal Revenue Code) limit the flexibility of the Company to
structure transactions that might otherwise be advantageous to the Company, and
may impair the Company's ability to conduct its business in the future.

     In addition, in connection with the acquisition of certain properties by
CarrAmerica Realty, L.P. and Carr Realty, L.P., the Company is restricted in its
ability to dispose of such properties in taxable transactions or to refinance
such properties.

CONFLICTS OF INTEREST

     Certain members of the Board and officers of the Company own CRLP Units
and, thus, may have interests that conflict with stockholders with respect to
business decisions affecting the Company and Carr Realty, L.P. In particular, a
holder of CRLP Units may suffer different and/or more adverse tax consequences
than the Company upon the sale or refinancing of some of the properties owned by
Carr

                                       4
<PAGE>
Realty, L.P. as a result of unrealized gain attributable to certain properties.
These CRLP Unit holders and the Company, therefore, may have different
objectives regarding the appropriate pricing and timing of a sale or refinancing
of properties. Although the Company, as the sole general partner of Carr Realty,
L.P., has the exclusive authority to determine whether and on what terms to sell
or refinance an individual property, these CRLP Unit holders might seek to
influence the Company not to sell or refinance a property, even though such sale
might otherwise be financially advantageous to the Company, or may seek to
influence the Company to refinance a property with a higher level of debt than
would be in the best interests of the Company.

MANAGEMENT, LEASING AND BROKERAGE RISKS

     The Company is subject to the risks associated with the property
management, leasing and brokerage businesses. These risks include the risk that
management contracts or service agreements with third-party owners will be lost
to competitors, that a property will be sold and the Company will lose the
contract, that contracts will not be renewed upon expiration or will not be
renewed on terms consistent with current terms and that leasing and brokerage
activity generally may decline. Each of these developments could adversely
affect the ability of the Company to make expected distributions to stockholders
or debt service payments.

LACK OF VOTING CONTROL OF OPERATING SUBSIDIARIES; OTHER SPECIAL CONSIDERATIONS
RELATED TO OMNIOFFICES

     Lack of Voting Control. The Company does not have voting control of Carr
Real Estate Services, Inc. ('Carr Services, Inc.'), CarrAmerica Development,
Inc. ('CarrAmerica Development') or OmniOffices, Inc. ('OmniOffices'), and may
acquire economic interests in similarly structured companies in the future
(collectively, the 'Operating Subsidiaries'). (Certain provisions in the Code
prohibit the Company from owning a significant portion of the voting stock of an
Operating Subsidiary, as described in '--Administration's Proposed Changes to
REIT Asset Test' below.) Carr Services, Inc., which conducts primarily fee-based
management and leasing, has capital stock which is divided into two classes:
voting common stock, approximately 92% and 8% of which is held by The Oliver
Carr Company ('OCCO') and Carr Realty, L.P., respectively; and nonvoting common
stock, approximately 96% and 4% of which is held by Carr Realty, L.P. and OCCO,
respectively. OCCO, as the holder of 92% of the voting common stock, has the
ability to elect the board of directors of Carr Services, Inc. CarrAmerica
Development, which conducts primarily fee-based development, has capital stock
which is divided into two classes: voting common stock, 96% and 4% of which is
held by OCCO and the Company, respectively; and nonvoting common stock, 100% of
which is held by the Company. OCCO, as the holder of 96% of the voting common
stock, has the ability to elect the board of directors of CarrAmerica
Development. Oliver T. Carr, Jr., who is Chairman of the Board of the Company
and a significant stockholder of the Company, beneficially owns a majority of
the voting stock of OCCO, which controls the election of directors of Carr
Services, Inc. and CarrAmerica Development. OmniOffices, which provides
executive office suites to commercial customers, has capital stock which is
divided into two classes: voting common stock and nonvoting common stock. The
voting stock is owned 17% by OCCO, 35% by SC-USREALTY and 48% by an entity owned
by the Company's six current executive officers. The nonvoting common stock is
owned entirely by the Company. The holders of the voting common stock control
the ability to elect the board of directors of OmniOffices.

     Although neither the right of Carr Realty, L.P. or the Company, as
applicable, to receive distributions with respect to its equity interest in each
Operating Subsidiary nor the terms of the promissory notes made by such
Operating Subsidiary and held by Carr Realty, L.P. or the Company, as
applicable, can be changed by the holder of the majority of the voting common
stock of such Operating Subsidiary, the Company will not be able to elect
directors of any Operating Subsidiary, and its ability to influence the
day-to-day decisions of each Operating Subsidiary is limited. As a result, the
board of directors and management of each Operating Subsidiary may implement
business policies or decisions that might not have been implemented by persons
elected by the Company and that are adverse to the interests of the Company or
that lead to adverse financial results, which could adversely impact the
Company's operating income and funds from operations.

                                       5
<PAGE>
     Lack of Liquidity for Stock.  None of the Operating Subsidiaries is a
public company, and there is no market for the equity securities held by the
Company or Carr Realty, L.P. in any Operating Subsidiary. Consequently, neither
the Company nor Carr Realty, L.P. has ready ability to liquidate its holdings in
any Operating Subsidiary.

     Constraints on Growth of OmniOffices. Certain provisions in the Code
prohibit the Company from having an investment in any Operating Subsidiary that
has a value in excess of 5% of the value of the Company's gross assets. These
provisions will limit the ability of OmniOffices to grow its business without
jeopardizing the Company's REIT qualification or, alternatively, incurring third
party debt (which may have to be guaranteed by the Company) or bringing into
OmniOffices additional investors. As of March 31, 1998, the Company's investment
in OmniOffices was such that the Company currently is precluded from making
substantial additional investments (either in the form of equity or a loan) in
OmniOffices. There can be no assurance that OmniOffices will be able to obtain
such third-party financing (or obtain it on attractive terms) or that suitable
additional investors can be identified. Limitations on the Company's ability to
fund additional growth of OmniOffices may preclude (or delay) OmniOffices from
pursuing growth opportunities that might otherwise be in its best interest.

     It is possible that the Company could elect in the future to dispose of
part or all of its equity interest in OmniOffices, including through a
distribution of the stock of OmniOffices to the Company's stockholders; however,
the Company is subject to certain contractual restrictions with SC-USREALTY that
could preclude or restrict such a distribution or other disposition. In
addition, the income from such a disposition would not qualify for purposes of
the 75% gross income test applicable to REITs, which could limit the ability of
the Company to dispose of all of its interest in OmniOffices (through a
distribution to stockholders or otherwise) in a single transaction. (For a more
detailed description of the income tests applicable to REITs, see 'Federal
Income Tax Considerations--Taxation of the Company.') Finally, because of
tax-related considerations specific to SC-USREALTY and SC-USREALTY's indirect
interest in OmniOffices through the Company, OmniOffices has agreed to conduct
its business subject to certain constraints, even though these constraints may
have the effect of precluding OmniOffices from undertaking transactions that
would be in the best interests of its other stockholders, including the Company.
Any reduction by the Company of its investment in OmniOffices would
correspondingly reduce the Company's right to receive distributions from
OmniOffices.

     Administration's Proposed Changes to REIT Asset Test. In order for the
Company to qualify as a REIT, the Company, at the close of each quarter of its
taxable year, must not own more than 10% of the outstanding voting securities of
any issuer, other than a qualified REIT subsidiary (a 'QRS') or another REIT
(for a more detailed discussion of this and other REIT qualification
requirements, see 'Federal Income Tax Considerations--Taxation of the Company').
The Clinton Administration's February 1998 budget proposal includes a proposal
to amend the 10% voting securities test by prohibiting a REIT from owning more
than 10% of the vote or value of all classes of stock of any corporation (other
than a QRS or another REIT). Stock owned by the Company in corporations prior to
the effective date of the proposal generally would be 'grandfathered' (i.e.,
with respect to such grandfathered stock, the REIT would be subject only to the
existing 10% voting securities test described above). However, if the
corporation in which such grandfathered stock is held were to engage in a new
trade or business or acquire substantial new assets, the grandfathered status
would terminate with respect to such stock.

     Because the Company owns the majority of the nonvoting stock of each of the
Operating Subsidiaries, the Company would not satisfy the proposed 10% value
limitation with respect to its stock interests in the Operating Subsidiaries.
However, as the Clinton Administration's proposal is currently drafted, stock
currently held by the Company in the Operating Subsidiaries should be
grandfathered. If any of the Operating Subsidiaries, however, were to engage in
new trades or businesses or acquire substantial new assets (or the Company were
to make a significant additional equity investment in an Operating Subsidiary),
then the stock held by the Company in such Operating Subsidiary would lose its
grandfathered status and the Company would fail to qualify as a REIT. Moreover,
the Company would not be able to own more than 10% of the vote or value of any
corporation (other than a QRS or another REIT) formed after the effective date
of the proposal. Thus, if enacted as currently drafted, the proposal would
materially impede the ability of the Company to engage in new activities or to
expand substantially its

                                       6

current activities, such as the executive office suites business and the
property development and management businesses.

CHANGES IN POLICIES

     The major policies of the Company, including its policies with respect to
development, acquisitions, financing, growth, operations, debt capitalization
and distributions, are determined by its Board. The Board may amend or revise
these and other policies from time to time without a vote of the stockholders of
the Company. A change in these policies could adversely affect the Company's
financial condition, results of operations, funds available for distributions to
stockholders, debt service or the market price of the Securities. The Company
cannot change its policy of seeking to maintain its qualification as a REIT
without the approval of the holders of a majority of the Common Stock.

CERTAIN TAX RISKS

     Tax Liabilities as a Consequence of the Failure to Qualify as a REIT. The
Company believes that it has been organized and has operated so as to qualify
for taxation as a REIT under the Internal Revenue Code of 1986, as amended (the
'Code'), commencing with its taxable year ended December 31, 1993, and intends
to continue to so operate. No assurance, however, can be given that the Company
has qualified for taxation as a REIT or will be able to remain so qualified.
Qualification as a REIT involves the application of highly technical and complex
Code provisions as to which there are only limited judicial and administrative
interpretations. Certain facts and circumstances that may be wholly or partially
beyond the Company's control may affect its ability to qualify or to continue to
qualify as a REIT. In addition, no assurance can be given that new legislation,
Treasury Regulations, administrative interpretations or court decisions will not
significantly change the tax laws with respect to the Company's qualification as
a REIT or the federal income consequences of such qualification to the Company.
If the Company fails to qualify as a REIT, it will be subject to federal income
tax (including any applicable alternative minimum tax) on its taxable income at
regular corporate rates and it will not be entitled to a deduction for dividends
paid to its stockholders. In addition, unless entitled to relief under certain
statutory provisions, the Company would be disqualified from taxation as a REIT
for the four taxable years following the year during which qualification is
lost. The additional tax incurred in such event would significantly reduce the
cash flow available for distribution to shareholders and to meet debt service
obligations. See 'Federal Income Tax Considerations--Taxation of the Company.'

     REIT Distribution Requirements and Potential Impact of Borrowings. To
obtain the favorable tax treatment associated with qualifying as a REIT under
the Code, the Company generally is required each year to distribute to its
shareholders at least 95% of its real estate investment trust taxable income.
See 'Federal Income Tax Considerations--Taxation of the Company (Annual
Distribution Requirements).' In addition, the Company will be subject to a 4%
nondeductible excise tax on the amount, if any, by which certain distributions
paid by it with respect to any calendar year are less than the sum of 85% of its
ordinary income, 95% of its capital gain net income and 100% of its real estate
investment trust taxable income from prior years that is not deemed to have been
distributed under the Code. Differences in timing between the receipt of income,
the payment of expenses and the inclusion of such income and the deduction of
such expenses in arriving at taxable income (of the Company or its
subsidiaries), or the effect of nondeductible capital expenditures, the creation
of reserves or required debt or amortization payments, could require the
Company, directly or through its subsidiaries, to borrow funds on a short-term
basis to meet the distribution requirements that are necessary to achieve the
tax benefits associated with qualifying as a REIT. In such instances, the
Company might need to borrow funds in order to avoid adverse tax consequences
even if management believed that the prevailing market conditions were not
otherwise favorable for such borrowings.

     Other Tax Liabilities. Even if the Company qualifies as a REIT, the Company
and certain of its subsidiaries will be subject to certain federal, state and
local taxes on its income and property. See 'Federal Income Tax
Considerations--Taxation of the Company and Other Tax Considerations.'

                                       7
<PAGE>
SPECIAL CONSIDERATIONS FOR FOREIGN INVESTORS

     In order to assist the Company in qualifying as a 'domestically controlled
REIT,' the Company's Articles of Incorporation, as amended (the 'Articles of
Incorporation'), contain certain provisions generally preventing foreign
investors (other than SC-USREALTY and its affiliates) from acquiring additional
shares of the Company's capital stock if, as a result of such acquisition, the
Company would fail to qualify as a 'domestically controlled REIT.' See 'Federal
Income Tax Considerations--Taxation of Holders of Common Stock--Taxation of
Non-U.S. Shareholders.' Accordingly, an acquisition of the Company's capital
stock would not likely be a suitable investment for non-U.S. shareholders other
than SC-USREALTY. See 'Description of Common Stock--Restrictions on Transfer.'

PRICE FLUCTUATIONS OF THE COMMON STOCK AND TRADING VOLUME;
SHARES AVAILABLE FOR FUTURE SALE

     A number of factors may adversely influence the price of the Company's
Common Stock in the public markets, many of which are beyond the control of the
Company. These factors include possible increases in market interest rates,
which may lead purchasers of Common Stock to demand a higher annual yield from
distributions by the Company in relation to the price paid for Common Stock, the
relatively low daily trading volume of REITs in general, including the Common
Stock, and any inability of the Company to invest the proceeds of a future
offering of Securities in a manner that will increase earnings per share. Sales
of a substantial number of shares of Common Stock, or the perception that such
sales could occur, could adversely affect prevailing market prices for shares.
The Company also may issue shares of Common Stock upon redemption of Units
issued in connection with the formation of the Company and subsequent
acquisitions. In addition, as of March 31, 1997, 4,416,900 shares of Common
Stock of the Company were reserved for issuance pursuant to stock and unit
options, and more shares may be reserved for such purpose in the future. These
shares will be available for sale in the public markets from time to time
pursuant to exemptions from registration requirements or upon registration. In
connection with the SC-USREALTY Transaction, the Company granted SC-USREALTY the
right to require the Company to file, at any time requested by SC-USREALTY, a
registration statement under the Securities Act of 1933 covering all or any of
the shares of Common Stock acquired by SC-USREALTY. In addition, in connection
with a forward equity sale transaction which the Company consummated, as well as
any such transaction which the Company may consummate in the future, the Company
may issue additional shares of Common Stock, and/or the purchasers of such
shares of Common Stock may sell shares issued to them. No prediction can be made
about the effect that future sales of Common Stock will have on the market
prices of shares.

POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES

     In order to assist the Company in maintaining its qualification as a REIT,
the Articles of Incorporation contain certain provisions generally limiting the
ownership of shares of capital stock by any single shareholder to 5% of the
outstanding Common Stock and/or 5% of any class or series of Preferred Stock
(with exceptions for persons who received more than 5% of the equity of the
Company pursuant to the contribution of assets to the Company in connection with
the initial public offering of the Company and SC-USREALTY and its affiliates).
The Board could waive this restriction if it were satisfied that ownership in
excess of the above ownership limit would not jeopardize the Company's status as
a REIT and the Board otherwise decided such action would be in the best
interests of the Company. Capital stock acquired or transferred in breach of the
limitation will be automatically transferred to a trust for the benefit of a
designated charitable beneficiary. See 'Description of Common
Stock--Restrictions on Transfer' for additional information regarding the limits
on ownership of shares of capital stock.

RESTRICTIONS ON ACQUISITION AND CHANGE IN CONTROL

     Various provisions of the Articles of Incorporation restrict the
possibility for acquisition or change in control of the Company, even if such
acquisition or change in control were in the stockholders' interest, including
the Ownership Limits (as defined herein), the staggered terms of the Company's
directors and the ability of the Board to authorize the issuance of preferred
stock without stockholder approval.

<PAGE>
                                USE OF PROCEEDS

     Unless otherwise specified in the applicable Prospectus Supplement, the net
proceeds from the sale of the Securities will be used for the acquisition and
development of additional office properties, as suitable opportunities arise,
for the repayment of certain outstanding indebtedness at such time, for capital
improvements to property and for working capital and other general corporate
purposes.

                      RATIOS OF EARNINGS TO FIXED CHARGES
   

     The Company's ratios of earnings to fixed charges for the period from
February 16, 1993 (commencement of operations) to December 31, 1993 and for the
years ended December 31, 1994, 1995, 1996 and 1997 were 1.75x, 1.81x, 1.91x,
1.74x and 2.01x, respectively.
    

     The ratios of earnings to fixed charges were computed by dividing earnings
by fixed charges. For this purpose, earnings consist of income (loss) before
gains from sales of property and extraordinary items plus fixed charges
(excluding interest cost capitalized). Fixed charges consist of interest expense
(including interest costs capitalized), the amortization of debt issuance costs
and rental expense deemed to represent interest expense.

   

     The Company issued preferred stock in 1996 and in August, November and
December 1997. Accordingly, the ratios of earnings to combined fixed charges and
preferred stock dividends for the years ended December 31, 1996 and 1997 were
1.71x and 1.73x, respectively.

                         DESCRIPTION OF DEBT SECURITIES

     The following description sets forth certain general terms and provisions
of the Debt Securities to which this Prospectus and any applicable Prospectus
Supplement may relate. The particular terms of the Debt Securities being offered
and the extent to which such general provisions may apply will be set forth in
the applicable indenture or in one or more indentures supplemental thereto and
described in a Prospectus Supplement relating to such Debt Securities.

GENERAL

     The Debt Securities will be direct, unsecured obligations of the Company
and may be either senior Debt Securities ('Senior Securities') or subordinated
Debt Securities ('Subordinated Securities'). The Debt Securities will be issued
under one or more indentures (the 'Indentures'). Senior Securities and
Subordinated 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 (a 'Trustee'). The Indentures will be
subject to and governed by the Trust Indenture Act of 1939, as amended (the
'TIA'). The statements made under this heading relating to the Debt Securities
and the Indentures are summaries of the anticipated provisions thereof, do not
purport to be complete and are qualified in their entirety by reference to the
Indentures and such Debt Securities. All section references appearing herein are
to sections of each Indenture unless otherwise indicated and capitalized terms
used but not defined under this heading shall have the respective meanings set
forth in each Indenture.

     The indebtedness represented by Subordinated Securities will be
subordinated in right of payment to the prior payment in full of the Senior Debt
of the Company as described under '--Subordination' below.

     Except as set forth in the applicable Indenture or in one or more
indentures supplemental thereto and described in a Prospectus Supplement
relating thereto, 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 the Company or as established in the applicable Indenture or 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.

     It is anticipated that each Indenture will provide that there may be more
than one Trustee thereunder, each with respect to one or more series of Debt
Securities. Any Trustee under an 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 director of a trust under the
applicable Indenture separate and apart from the trust administered by any other
Trustee, and, except as otherwise indicated herein, any action described herein
to be taken by each 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.

     The Prospectus Supplement relating to any series of Debt Securities being
offered will contain the specific terms thereof, including, without limitation:

          (1) The title of such Debt Securities and whether such Debt Securities
     are Senior Securities or Subordinated 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 will be issued and, if other than the principal amount thereof,
     the portion of the principal amount thereof payable upon declaration of
     acceleration of the maturity thereof;

          (4) If convertible in whole or in part into Common Stock or Preferred
     Stock, the terms on which such Debt Securities are convertible, including
     the initial conversion price or rate (or method for determining the same),
     the portion that is convertible and the conversion period, and any
     applicable limitations on the ownership or transferability of the Common
     Stock or Preferred Stock receivable on conversion;

                                       10
<PAGE>
          (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 dates on which any
     such interest will be payable, the regular record dates for such interest
     payment dates, or the method by which such dates shall be 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 the Company 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, in whole or in part, at the option of the Company, if the Company
     is to have such an option;

          (10) The obligation, if any, of the Company 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 or the date and dates on which the price or prices at which
     and the other terms and conditions upon which such Debt Securities will be
     redeemed, repaid or purchased, in 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) Any additions to, modifications of or deletions from the terms of
     such Debt Securities with respect to Events of Default or covenants set
     forth in the applicable Indenture;

          (14) Whether such Debt Securities will be issued in certificate or
     book-entry form;

          (15) 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;

          (16) The applicability, if any, of the defeasance and covenant
     defeasance provisions of Article Fourteen of the applicable Indenture;

          (17) Whether and under what circumstances the Company will pay any
     additional amounts on such Debt Securities in respect of any tax,
     assessment or governmental charge and, if so, whether the Company will have
     the option to redeem such Debt Securities in lieu of making such payment;
     and

          (18) Any other terms of such Debt Securities not inconsistent with the
     provisions of the applicable Indenture (Section 301).

     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'). Special federal income tax, accounting
and other considerations applicable to Original Issue Discount Securities will
be described in the applicable Prospectus Supplement.

     Except as set forth in the applicable Indenture or in one or more
indentures supplemental thereto, the applicable Indenture will not contain any
provisions that would limit the ability of the Company to

                                       11
<PAGE>
incur indebtedness or that would afford Holders of Debt Securities protection in
the event of a highly leveraged or similar transaction involving the Company or
in the event of a change of control. Restrictions on ownership and transfers of
the Company's Common Stock and Preferred Stock are designed to preserve its
status as a REIT and, therefore, may act to prevent or hinder a change of
control. See 'Description of Preferred Stock--Restrictions on Ownership' and
'Description of Common Stock-- Restrictions on Transfer.' 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 the Company that are described below, including any addition of a
covenant or other provision providing event risk or similar protection.

DENOMINATION, 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 (Section 302).

     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, the
address of which will be stated in the applicable Prospectus Supplement;
provided that, at the option of the Company, payment of interest may be made by
check mailed to the address of the person entitled thereto as it appears in the
applicable register for such Debt Securities or by wire transfer of funds to
such person at an account maintained within the United States (Sections 301,
305, 306, 307 and 1002).

     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 on the applicable regular 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
Trustee, notice whereof shall be given to the Holder of such Debt Security not
less than ten 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 Indenture
(Section 307).

     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 referred
to above. 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 or exchange thereof at
the corporate trust office of the applicable Trustee. Every Debt Security
surrendered for conversion, registration of transfer or exchange must 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 the Company 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 the Company with respect to any
series of Debt Securities, the Company 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 the Company will be required to maintain a
transfer agent in each place of payment for such series. The Company may at any
time designate additional transfer agents with respect to any series of Debt
Securities (Section 1002).

     Neither the Company 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) 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 (Section 305).

                                       12
<PAGE>
MERGER, CONSOLIDATION OR SALE

     The Company will be permitted to consolidate with, or sell, lease or convey
all or substantially all of its assets to, or merge with or into, any other
entity provided that (a) either the Company shall be the continuing entity, or
the successor entity (if other than the Company) formed by or resulting from any
such consolidation or merger or which shall have received the transfer of such
assets 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 each
Indenture; (b) immediately after giving effect to such transaction and treating
any indebtedness that becomes an obligation of the Company or any Subsidiary as
a result thereof as having been incurred by the Company or Subsidiary at the
time of such transaction, no Event of Default under the Indentures, 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 officer's certificate
and legal opinion covering such conditions shall be delivered to each Trustee
(Sections 801 and 803).

CERTAIN COVENANTS

     Existence. Except as described under '--Merger, Consolidation or Sale'
above, the Company will be required to do or cause to be done all things
necessary to preserve and keep in full force and effect its existence, rights
(by articles of incorporation, by-laws and statute) and franchises; provided,
however, that the Company 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. The Company will be required to cause all of its
material properties used or useful in the conduct of its business or the
business of any Subsidiary (as defined below) 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 the Company may
be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times (Section 1007); provided,
however, that the Company shall not be prevented from selling or otherwise
disposing for value its properties in the ordinary course of business.

     Insurance. The Company will be required to, and will be required to cause
each of its Subsidiaries to keep all of its insurable properties insured against
loss or damage at least equal to their then full insurable value with insurers
of recognized responsibility and, if described in the applicable Prospectus
Supplement, having a specified rating from a recognized insurance rating service
(Section 1008).

     Payment of Taxes and Other Claims. The Company will be required to 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
Company 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
Company or any Subsidiary; provided, however, that the Company 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 1009).


     Provision of Financial Information. Whether or not the Company is subject
to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), the Company will be required, to the extent permitted under the
Exchange Act, to file with the U.S. Securities and Exchange Commission (the
"Commission" or the "SEC") the annual reports, quarterly reports and other
documents which the Company would have been required to file with the Commission
pursuant to such Sections 13 or 15(d) if the Company were so subject (the
'Financial Information'), such documents to be filed with the Commission on or
prior to the respective dates (the 'Required Filing Dates') by which the Company
would have been required so to file such documents if the Company were so
subject. The Company also will in any event (x) within 15 days of each Required
Filing Date (i) transmit by mail to all Holders of Debt Securities, as their
names and addresses appear in the Security Register, without cost to such
Holders, copies of the Financial Information and (ii) file with the Trustee
copies of the Financial Information, and (y) if filing such documents by the
Company with the Commission is not permitted


                                       13

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 1010).

ADDITIONAL COVENANTS AND/OR MODIFICATIONS TO THE COVENANTS DESCRIBED ABOVE

     Any additional covenants of the Company and/or modifications to the
covenants described above with respect to any Debt Securities or series thereof,
including any covenants relating to limitations on incurrence of indebtedness or
other financial covenants, will be set forth in the applicable Indenture or an
indenture supplemental thereto and described in the Prospectus Supplement
relating thereto.

EVENTS OF DEFAULT, NOTICE AND WAIVER

     Each Indenture will provide that the following events are 'Events of
Default' with respect to any series of Debt Securities issued thereunder: (i)
default in the payment of any installment of interest on any Debt Security of
such series; (ii) default in the payment of principal of (or premium, if any,
on) any Debt Security of such series when due and payable; (iii) default in
making any sinking fund payment as required for any Debt Security of such
series; (iv) default in the performance, or breach, of any other covenant or
warranty of the Company contained in the applicable Indenture (other than a
covenant added to the 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; (v) default under
any bond, debenture, note or other evidence of indebtedness for money borrowed
by the Company or any of its Subsidiaries (including obligations under leases
required to be capitalized on the balance sheet of the lessee under GAAP)
representing recourse indebtedness or indebtedness guaranteed by such party in
an aggregate principal amount in excess of $5,000,000, 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 the Company or any
of its Subsidiaries (including the leases) representing recourse indebtedness or
indebtedness guaranteed by such party in an aggregate principal amount in excess
of $5,000,000, whether the indebtedness now exists or shall hereafter be
created, which default shall have resulted in the indebtedness becoming or being
declared due and payable prior to the date on which it would otherwise have
become due and payable, or the obligations being accelerated, without the
acceleration having been rescinded or annulled; (vi) certain events of
bankruptcy, insolvency or reorganization, or court appointment of a receiver,
liquidator or trustee of the Company or any Significant Subsidiary (as defined
below) for all or substantially all of the property of the Company or any
Significant Subsidiary; and (vii) any other Event of Default provided with
respect to a particular series of Debt Securities (Section 501).

     'Significant Subsidiary' means any Subsidiary that is a 'significant
subsidiary' (within the meaning of Regulation S-X promulgated under the
Securities Act) of the Company.

     'Subsidiary' means a corporation, partnership or other entity a majority of
the voting power of the voting equity securities or the outstanding equity
interests of which are owned, directly or indirectly, by the Company or by one
or more other Subsidiaries of the Company. For the purposes of this definition,
'voting equity securities' means equity securities having voting power for the
election of directors, whether at all times or only so long as no senior class
of security has such voting power by reason of any contingency. The term
'Subsidiary' does not include Carr Services, Inc., CarrAmerica Development or
OmniOffices, as the Company does not own or control a majority of the
outstanding voting stock of such entities.

     If an Event of Default under any 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% of the
principal amount of the Outstanding Debt Securities of that series will have the
right to 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 the Company (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
any 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

                                       14
<PAGE>
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) the Company shall have 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 such Indenture (Section
502). Each Indenture also will 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 (Section 513).

     Each 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, 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 specified responsible officers of such Trustee
consider such withholding to be in the interest of such Holders (Section 601).

     Each Indenture will provide that no Holders of Debt Securities of any
series may institute any proceedings, judicial or otherwise, with respect to
such Indenture or for any remedy thereunder, except in the cases of failure of
the applicable Trustee, for 60 days, to act after it has received a written
request to institute proceedings in respect of an Event of Default from the
Holders of not less than 25% in principal amount of the Outstanding Debt
Securities of such series, as well as an offer of indemnity reasonably
satisfactory to it (Section 507). This provision will not prevent, however, any
Holder of Debt Securities from instituting suit for the enforcement of payment
of the principal of (and premium, if any) and interest on such Debt Securities
at the respective due dates thereof (Section 508).

     Subject to provisions in each Indenture relating to its duties in case of
default, no Trustee will be under any obligation to exercise any of its rights
or powers under an 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 Trustee thereunder reasonable security or
indemnity (Section 602). 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 an 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, a 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
(Section 512).

     Within 120 days after the close of each fiscal year, the Company 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 (Section 1011).

MODIFICATION OF THE INDENTURES

     Modifications and amendments of an Indenture will be permitted to be made
only with the consent of the Holders of not less than a majority in principal
amount of all Outstanding Debt Securities issued under such 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

                                       15
<PAGE>
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 the principal of (or 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 applicable 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 applicable 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 (Section 902).

     The Holders of not less than a majority in principal amount of Outstanding
Debt Securities of each series affected thereby will have the right to waive
compliance by the Company with certain covenants in such Indenture (Section
1013).

     Modifications and amendments of an Indenture will be permitted to be made
by the Company 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 the Company as obligor under such Indenture;
(ii) to add to the covenants of the Company for the benefit of the Holders of
all or any series of Debt Securities or to surrender any right or power
conferred upon the Company in the Indenture; (iii) to add Events of Default for
the benefit of the Holders of all or any series of Debt Securities; (iv) to add
or change any provisions of an 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 an 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 Stock or
Preferred Stock of the Company; (viii) to provide for the acceptance of
appointment by a successor Trustee or facilitate the administration of the
trusts under an Indenture by more than one Trustee; (ix) to cure any ambiguity,
defect or inconsistency in an 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 an 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 (Section 901).

     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 any 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

                                       16
<PAGE>
applicable Indenture, and (iv) Debt Securities owned by the Company or any other
obligor under the Debt Securities or any affiliate of the Company 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 (Section 501). A meeting will be
permitted to be called at any time by the applicable Trustee, and also, upon
request, by the Company or the Holders of at least 10% in principal amount of
the Outstanding Debt Securities of such series, in any such case upon notice
given as provided in the Indenture. Except for any consent that must be given by
the Holder of each Debt Security affected by certain modifications and
amendments of an 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 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
an 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, each Indenture will provide that
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 and other action that such 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 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 such Indenture.

SUBORDINATION

     The terms and conditions, if any, upon which the Debt Securities are
subordinated to other indebtedness of the Company will be set forth in the
applicable Prospectus Supplement relating thereto. Such terms will include a
description of the indebtedness ranking senior to the Debt Securities, the
restrictions on payments to the Holders of such Debt Securities while a default
with respect to such senior indebtedness in continuing, the restrictions, if
any, on payments to the Holders of such Debt Securities following an Event of
Default, and provisions requiring Holders of such Debt Securities to remit
certain payments to holders of senior indebtedness.

DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE

     The Company may be permitted under the applicable Indenture 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

                                       17
<PAGE>
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, if the provisions of Article Fourteen are
made applicable to the Debt Securities of or within any series pursuant to
Section 301 of such Indenture, the Company 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') (Section 1402) or (b) to be released from its obligations with
respect to such Debt Securities under certain specified sections of Article Ten
of such Indenture as specified in the applicable Prospectus Supplement and any
omission to comply with such obligations shall not constitute an Event of
Default with respect to such Debt Securities ('covenant defeasance') (Section
1403), in either case upon the irrevocable deposit by the Company 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 without reinvestment 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.

     Such a trust will only be permitted to be established if, among other
things, the Company has delivered to the applicable Trustee an opinion of
counsel (as specified in the applicable Indenture) to the effect that the
Holders of such Debt Securities will not recognize income, gain or loss for
federal income tax purposes as a result of such defeasance or covenant
defeasance and will be subject to 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, will be required to 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 (Section 1404).

     '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 timely
payment of which is unconditionally guaranteed as a full faith and credit
obligation of the United States of America or such 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 applicable 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 (Section 101).

     Unless otherwise provided in the applicable Prospectus Supplement, if after
the Company 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 applicable 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 will be deemed to have been, and
will be, fully discharged and satisfied

                                       18
<PAGE>
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 ECU both within the European Monetary System 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.

     In the event the Company effects covenant defeasance with respect to any
Debt Securities and such Debt Securities are declared due and payable because of
the occurrence of any Event of Default other than the Event of Default described
in clause (iv) under '--Events of Default, Notice and Waiver' above with respect
to certain specified sections of Article Ten of each Indenture (which sections
would no longer be applicable to such Debt Securities as a result of such
covenant defeasance) or described in clause (vii) under '--Events of Default,
Notice and Waiver' above with respect to any other covenant as to which there
has been covenant defeasance, the amount in such currency, currency unit or
composite currency in which such Debt Securities are payable, and Government
Obligations on deposit with the applicable Trustee, will be sufficient to pay
amounts due on such Debt Securities at the time of their stated maturity but may
not be sufficient to pay amounts due on such Debt Securities at the time of the
acceleration resulting from such Default. However, the Company would remain
liable to make payment of such amounts due at the time of acceleration.

     The applicable Prospectus Supplement may further describe the provisions,
if any, permitting such defeasance or covenant defeasance, including any
modifications to 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 Stock or Preferred Stock will be set forth in the
applicable Prospectus Supplement relating thereto. Such terms will include
whether such Debt Securities are convertible into Common Stock or Preferred
Stock, 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 the Company, the events requiring an adjustment of the conversion price and
provisions affecting conversion in the event of the redemption of such Debt
Securities and any restrictions on conversion, including restrictions directed
at maintaining the Company's REIT status.

REDEMPTION OF SECURITIES

     The Indenture provides that the Debt Securities may be redeemed at any time
at the option of the Company, in whole or in part, at the redemption price,
except as may otherwise be provided in connection with any Debt Securities or
series thereof.

     From and after notice has been given as provided in the Indenture, if funds
for the redemption of any Debt Securities called for redemption shall have been
made available on such redemption date, such Debt Securities will cease to bear
interest on the date fixed for such redemption specified in such notice, and the
only right of the Holders of the Debt Securities will be to receive payment of
the redemption price.

     Notice of any optional redemption of any Debt Securities will be given to
Holders at their addresses, as shown in the Company's books and records, not
more than 60 nor less than 30 days prior to the date fixed for redemption. The
notice of redemption will specify, among other items, the redemption price and
the principal amount of the Debt Securities held by such Holder to be redeemed.

                                       19
<PAGE>
     If the Company elects to redeem Debt Securities, it will notify the Trustee
at least 45 days prior to the redemption date (or such shorter period as
satisfactory to the Trustee) of the aggregate principal amount of Debt
Securities to be redeemed and the redemption date. If less than all of the Debt
Securities are to be redeemed, the Trustee shall select the Debt Securities to
be redeemed pro rata, by lot or in such manner as it shall deem fair and
appropriate.

                         DESCRIPTION OF PREFERRED STOCK

     The Company is authorized to issue 15,000,000 shares of Preferred Stock. As
of March 31, 1998, there were 780,000 shares of Series A Cumulative Convertible
Redeemable Preferred Stock outstanding (1,740,000 were issued originally) and
8,000,000 shares of Series B Cumulative Redeemable Preferred Stock issued and
outstanding. There were also 600,000 shares of Series C Cumulative Redeemable
Preferred Stock issued and outstanding and underlying 6,000,000 depositary
shares which are traded publicly. In addition, there were 200,000 shares of
Series D Cumulative Redeemable Preferred Stock issued and outstanding and
underlying 2,000,000 depositary shares which are traded publicly.

     Under the Company's Articles of Incorporation, the Board may from time to
time establish and issue one or more series of Preferred Stock. The Board may
classify or reclassify any unissued Preferred Stock by setting or changing the
number, designation, preference, conversion or other rights, voting powers,
restrictions, limitations as to dividends, qualifications and terms or
conditions of redemption of such series (a 'Designating Amendment').

     The following description of the Preferred Stock sets forth certain general
terms and provisions of the Preferred Stock to which any Prospectus Supplement
may relate. The statements below describing the Preferred Stock are in all
respects subject to and qualified in their entirety by reference to the
applicable provisions of the Company's Articles of Incorporation and the
Company's bylaws (the 'Bylaws').

GENERAL

     The Board is empowered by the Company's Articles of Incorporation to
designate and issue from time to time one or more series of Preferred Stock
without stockholder approval. The Board may determine the relative rights,
preferences and privileges of each series of Preferred Stock so issued. Because
the Board has the power to establish the preferences and rights of each series
of Preferred Stock, it may afford the holders of any series of Preferred Stock
preferences, powers and rights, voting or otherwise, senior to the rights of
holders of Common Stock. The Preferred Stock will, when issued, be fully paid
and nonassessable.

     The Prospectus Supplement relating to any Preferred Stock offered thereby
will contain the specific terms thereof, including, without limitation:

          (1) The title and stated value of such Preferred Stock;

          (2) The number of such shares of Preferred Stock offered, the
     liquidation preference per share and the offering price of such Preferred
     Stock;

          (3) The dividend rate(s), period(s) and/or payment date(s) or
     method(s) of calculation thereof applicable to such Preferred Stock;

          (4) The date from which dividends on such Preferred Stock will
     accumulate, if applicable;

          (5) The procedures for any auction and remarketing, if any, for such
     Preferred Stock;

          (6) The provision for a sinking fund, if any, for such Preferred
     Stock;

          (7) The provision for redemption, if applicable, of such Preferred
     Stock;

          (8) Any listing of such Preferred Stock on any securities exchange;

          (9) The terms and conditions, if applicable, upon which such Preferred
     Stock will be convertible into Common Stock of the Company, including the
     conversion price (or manner of calculation thereof);

                                       20

          (10) Any other specific terms, preferences, rights, limitations or
     restrictions of such Preferred Stock;

          (11) A discussion of federal income tax considerations applicable to
     such Preferred Stock;

          (12) The relative ranking and preferences of such Preferred Stock as
     to dividend rights and rights upon liquidation, dissolution or winding up
     of the affairs of the Company;

          (13) Any limitations on issuance of any series of Preferred Stock
     ranking senior to or on a parity with such series of Preferred Stock as to
     dividend rights and rights upon liquidation, dissolution or winding up of
     the affairs of the Company; 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 the Company as a REIT.

RANK

     Unless otherwise specified in the Prospectus Supplement, the Preferred
Stock will, with respect to dividend rights and rights upon liquidation,
dissolution or winding up of the Company, rank (i) senior to all classes or
series of Common Stock of the Company, and to all equity securities ranking
junior to such Preferred Stock, (ii) on a parity with all equity securities
issued by the Company the terms of which specifically provide that such equity
securities rank on a parity with the Preferred Stock, and (iii) junior to all
equity securities issued by the Company the terms of which specifically provide
that such equity securities rank senior to the Preferred Stock. The term 'equity
securities' does not include convertible debt securities.

DIVIDENDS

     Holders of the Preferred Stock of each series will be entitled to receive,
when, as and if declared by the Board, out of assets of the Company legally
available for payment, cash dividends (or dividends in kind or in other property
if expressly permitted and described in the applicable Prospectus Supplement) at
such rates and on such dates as will be set forth in the applicable Prospectus
Supplement. Each such dividend will be payable to holders of record as they
appear on the stock transfer books of the Company on such record dates as are
fixed by the Board.

     Dividends on any series of Preferred Stock 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 Stock for
which dividends are non-cumulative, then the holders of such series of the
Preferred Stock will have no right to receive a dividend in respect of the
dividend period ending on such dividend payment date, and the Company 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.

     Unless otherwise specified in the Prospectus Supplement, if any shares of
Preferred Stock of any series are outstanding, no full dividends will be
declared or paid or set apart for payment on any capital stock of the Company of
any other series ranking, as to dividends, on a parity with or junior to the
Preferred Stock of such series for any period unless (i) if such series of
Preferred Stock 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 Stock of such
series for all past dividend periods and the then current dividend period or
(ii) if such series of Preferred Stock 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 Stock of such series. When dividends
are not paid in full (or a sum sufficient for such full payment is not so set
apart) upon Preferred Stock of any series and the shares of any other series of
Preferred Stock ranking on a parity as to dividends with the Preferred Stock of
such series, all dividends declared upon Preferred Stock of such series and any
other series of Preferred Stock ranking on a parity as to dividends with such
Preferred Stock will be declared pro rata so that the amount of dividends
declared per share of Preferred Stock of such series and such other series of
Preferred Stock

                                       21
<PAGE>
will in all cases bear to each other the same ratio that accrued dividends per
share on the Preferred Stock of such series (which will not include any
accumulation in respect of unpaid dividends for prior dividend periods if such
Preferred Stock do not have a cumulative dividend) and such other series of
Preferred Stock bear to each other. No interest, or sum of money in lieu of
interest, will be payable in respect of any dividend payment or payments on
Preferred Stock of such series which may be in arrears.

     Except as provided in the immediately preceding paragraph, unless (i) if
such series of Preferred Stock has a cumulative dividend, full cumulative
dividends on the Preferred Stock 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 Stock does not have a
cumulative dividend, full dividends on the Preferred Stock 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 Stock or other capital stock ranking
junior to the Preferred Stock of such series as to dividends and upon
liquidation) will be declared or paid or set aside for payment or other
distribution upon the Common Stock, or any other capital stock of the Company
ranking junior to or on a parity with the Preferred Stock of such series as to
dividends or upon liquidation, nor will any Common Stock, or any other capital
stock of the Company ranking junior to or on a parity with the Preferred Stock
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 stock) by the
Company (except by conversion into or exchange for other capital stock of the
Company ranking junior to the Preferred Stock of such series as to dividends and
upon liquidation).

     If for any taxable year, the Company elects to designate as 'capital gains
dividends' (as defined in Section 857 of the Code) any portion (the 'Capital
Gains Amount') of the dividends (within the meaning of the Code) paid or made
available for the year to holders of all classes of capital stock (the 'Total
Dividends'), then the portion of the Capital Gains Amount that will be allocable
to the holders of shares of Preferred Stock will be the Capital Gains Amount
multiplied by a fraction, the numerator of which shall be the total dividends
(within the meaning of the Code) paid or made available to the holders of shares
of Preferred Stock for the year and the denominator of which shall be the Total
Dividends.

REDEMPTION

     If so provided in the applicable Prospectus Supplement, the Preferred Stock
will be subject to mandatory redemption or redemption at the option of the
Company, in 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 Stock that is
subject to mandatory redemption will specify the number of shares of such
Preferred Stock that will be redeemed by the Company 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
will not, if such Preferred Stock does 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 Stock of any series is payable only from the net
proceeds of the issuance of capital stock of the Company, the terms of such
Preferred Stock may provide that, if no such capital stock 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 Stock will
automatically and mandatorily be converted into the applicable capital stock of
the Company pursuant to conversion provisions specified in the applicable
Prospectus Supplement.

     Notwithstanding the foregoing, unless (i) if such series of Preferred Stock
has a cumulative dividend, full cumulative dividends on all Preferred Stock of
any series 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 current dividend period and (ii) if such
series of Preferred Stock does not have a cumulative dividend, full dividends of
the Preferred Stock of any series have been or

                                       22
<PAGE>
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
Preferred Stock of any series shall be redeemed unless all outstanding Preferred
Stock of such series are simultaneously redeemed; provided, however, that the
foregoing shall not prevent the purchase or acquisition of Preferred Stock of
such series to preserve the REIT status of the Company or pursuant to a purchase
or exchange offer made on the same terms to holders of all outstanding Preferred
Stock of such series. In addition, unless (i) if such series of Preferred Stock
has a cumulative dividend, full cumulative dividends on all outstanding shares
of any series of Preferred Stock 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 dividends periods and the then current dividend period, and
(ii) if such series of Preferred Stock does not have a cumulative dividend, full
dividends on the Preferred Stock 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 current dividend period, the Company will not
purchase or otherwise acquire directly or indirectly any Preferred Stock of such
series (except by conversion into or exchange for capital stock of the Company
ranking junior to the Preferred Stock of such series as to dividends and upon
liquidation); provided, however, that the foregoing will not prevent the
purchase or acquisition of Preferred Stock of such series to preserve the REIT
status of the Company or pursuant to a purchase or exchange offer made on the
same terms to holders of all outstanding Preferred Stock of such series.

     If fewer than all of the outstanding shares of Preferred Stock of any
series are to be redeemed, the number of shares to be redeemed will be
determined by the Company 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
or for which redemption is requested by such holder (with adjustments to avoid
redemption of fractional shares) or by lot in a manner determined by the
Company.

     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 Stock of
any series to be redeemed at the address shown on the stock transfer books of
the Company. Each notice will state: (i) the redemption date; (ii) the number of
shares and series of Preferred Stock to be redeemed; (iii) the redemption price;
(iv) the place or places where certificates for such Preferred Stock 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 of the Preferred Stock of any series are to be
redeemed, the notice mailed to each such holder thereof will also specify the
number of shares of Preferred Stock to be redeemed from each such holder. If
notice of redemption of any Preferred Stock has been given and if the funds
necessary for such redemption have been set aside by the Company in trust for
the benefit of the holders of any Preferred Stock so called for redemption, then
from and after the redemption date dividends will cease to accrue on such
Preferred Stock, and all rights of the holders of such shares will terminate,
except the right to receive the redemption price.

LIQUIDATION PREFERENCE

     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the affairs of the Company, then, before any distribution or payment is made to
the holders of any Common Stock or any other class or series of capital stock of
the Company ranking junior to the Preferred Stock in the distribution of assets
upon any liquidation, dissolution or winding up of the Company, the holders of
each series of Preferred Stock shall be entitled to receive out of assets of the
Company 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 will not include any accumulation in respect
of unpaid dividends for prior dividend periods if such Preferred Stock does not
have a cumulative dividend). After payment of the full amount of the liquidating
distributions to which they are entitled, the holders of Preferred Stock will
have no right or claim to any of the remaining assets of the Company. In the
event that, upon any such voluntary or involuntary liquidation, dissolution or
winding up, the available assets of the Company are insufficient to pay the
amount of the liquidating distributions on all outstanding Preferred Stock and
the corresponding amounts payable on all shares of other classes or series of
capital stock of the Company ranking on a

                                       23
<PAGE>
parity with the Preferred Stock in the distribution of assets, then the holders
of the Preferred Stock and all other such classes or series of capital stock
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 Stock, the remaining assets of the Company will be distributed among
the holders of any other classes or series of capital stock ranking junior to
the Preferred Stock 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
the Company with or into any other corporation, trust or entity, or the sale,
lease or conveyance of all or substantially all of the property or business of
the Company, will not be deemed to constitute a liquidation, dissolution or
winding up of the Company.

VOTING RIGHTS

     Holders of Preferred Stock 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.

     Whenever dividends on any Preferred Stock shall be in arrears for six or
more consecutive quarterly periods, the holders of such Preferred Stock (voting
separately as a class with all other series of Preferred Stock upon which like
voting rights have been conferred and are exercisable) will be entitled to vote
for the election of two additional directors of the Company at a special meeting
called by the holders of record of at least ten percent (10%) of any series of
Preferred Stock so in arrears (unless such request is received less than 90 days
before the date fixed for the next annual or special meeting of the
shareholders) or at the next annual meeting of stockholders, and at each
subsequent annual meeting until (i) if such series of Preferred Stock has a
cumulative dividend, all dividends accumulated on such shares of Preferred Stock
for the past dividend periods and the then current dividend period shall have
been fully paid or declared and a sum sufficient for the payment thereof set
aside for payment or (ii) if such series of Preferred Stock do not have a
cumulative dividend, four consecutive quarterly dividends shall have been fully
paid or declared and a sum sufficient for the payment thereof set aside for
payment. In such case, the entire Board will be increased by two directors.

     Unless provided otherwise for any series of Preferred Stock, so long as any
shares of Preferred Stock remain outstanding, the Company will not, without the
affirmative vote or consent of the holders of at least two-thirds of each series
of shares of Preferred Stock 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 stock ranking prior to such series of Preferred
Stock with respect to the payment of dividends or the distribution of assets
upon liquidation, dissolution or winding up or reclassify any authorized capital
stock of the Company into 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 the Company's
Articles of Incorporation or the Designating Amendment for such series of
Preferred Stock, whether by merger, consolidation or otherwise (an 'Event'), so
as to materially and adversely affect any right, preference, privilege or voting
power of such series of Preferred Stock or the holders thereof; provided,
however, with respect to the occurrence of any of the Events set forth in clause
(ii) above, so long as the shares of Preferred Stock remain outstanding with the
terms thereof materially unchanged, taking into account that upon the occurrence
of an Event the Company may not be the surviving entity, the occurrence of any
such Event will not be deemed to materially and adversely affect such rights,
preferences, privileges or voting power of holders of Preferred Stock and
provided further that (x) any increase in the amount of the authorized Preferred
Stock or the creation or issuance of any other series of Preferred Stock, or (y)
any increase in the amount of authorized shares of such series or any other
series of Preferred Stock, in each case ranking on a parity with or junior to
the Preferred Stock of such series with respect to payment of dividends or the
distribution of assets upon liquidation, dissolution or winding up, will 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 Preferred Stock

                                       24
<PAGE>
of such series 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 Stock
is convertible into Common Stock will be set forth in the applicable Prospectus
Supplement relating thereto. Such terms will include the number of shares of
Common Stock into which the Preferred Stock 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
Stock or the Company, the events requiring an adjustment of the conversion price
and provisions affecting conversion in the event of the redemption of such
series of Preferred Stock.

RESTRICTIONS ON OWNERSHIP

     As discussed below under 'Description of Common Stock--Restrictions on
Transfer--Ownership Limits,' for the Company to qualify as a REIT under the
Code, no more than 50% in value of its outstanding capital stock may be owned,
directly or indirectly, by five or fewer 'individuals' (as defined in the Code
to include certain entities) during the last half of a taxable year (other than
the first year) or during a proportionate part of a shorter taxable year. To
assist the Company in meeting this requirement, the Articles of Incorporation
provide that no holder of Preferred Stock may own, or be deemed to own by virtue
of certain attribution provisions of the Code, more than 5% of any class or
series of Preferred Stock and/or more than 5% of the issued and outstanding
shares of Common Stock, subject to certain exceptions specified in the Articles
of Incorporation. See 'Description of Common Stock--Restrictions on
Transfer--Ownership Limits.'

REGISTRAR AND TRANSFER AGENT

     The Registrar and Transfer Agent for the Preferred Stock will be set forth
in the applicable Prospectus Supplement.

                          DESCRIPTION OF COMMON STOCK

GENERAL

     The Company is authorized to issue 90,000,000 shares of Common Stock. The
outstanding Common Stock entitles the holder to one vote on all matters
presented to stockholders for a vote. Holders of Common Stock have no preemptive
rights. At April 13, 1998, there were 69,291,700 shares of Common Stock
outstanding.

     Shares of Common Stock currently outstanding are listed for trading on the
New York Stock Exchange (the 'NYSE'). The Company will apply to the NYSE to list
the additional Common Stock to be sold pursuant to any Prospectus Supplement,
and the Company anticipates that such shares will be so listed.

     Subject to such preferential rights as may be granted by the Board in
connection with the future issuance of Preferred Stock, holders of Common Stock
are entitled to one vote per share on all matters to be voted on by stockholders
and are entitled to receive ratably such dividends as may be declared on the
Common Stock by the Board in its discretion from funds legally available
therefor. In the event of the liquidation, dissolution or winding up of the
Company, holders of Common Stock are entitled to share ratably in all assets
remaining after payment of all debts and other liabilities and any liquidation
preference of the holders of Preferred Stock. Holders of Common Stock have no
subscription, redemption, conversion or preemptive rights. Matters submitted for
stockholder approval generally require a majority vote of the shares present and
voting thereon.

                                       25
<PAGE>
ADVANCE NOTICE OF DIRECTOR NOMINATIONS AND NEW BUSINESS

     The Bylaws of the Company provide that, with respect to an annual meeting
of stockholders, the proposal of business to be considered by stockholders may
be made only (i) by or at the direction of the Board or (ii) by a stockholder
who is entitled to vote at the meeting and who has complied with the advance
notice procedures set forth in the Bylaws. In addition, with respect to any
meeting of stockholders, nominations of persons for election to the Board may be
made only (i) by or at the direction of the Board or (ii) by any stockholder of
the Company who is entitled to vote at the meeting and has complied with the
advance notice provisions set forth in the Bylaws.

RESTRICTIONS ON TRANSFER

     Ownership Limits. The Company's Articles of Incorporation contain certain
restrictions on the number of shares of Common Stock that individual
shareholders may own. For the Company to qualify as a REIT under the Code, no
more than 50% in value of its outstanding capital stock may be owned, directly
or indirectly, by five or fewer 'individuals' (as defined in the Code to include
certain entities) during the last half of a taxable year (other than the first
year) or during a proportionate part of a shorter taxable year. The capital
stock also must be beneficially owned by 100 or more persons during at least 335
days of a taxable year or during a proportionate part of a shorter taxable year.
Because the Company intends to maintain its qualification as a REIT, the
Company's Articles of Incorporation contain certain restrictions on the
ownership and transfer of capital stock, including Common Stock, intended to
ensure compliance with these requirements.

     Subject to certain exceptions specified in the Articles of Incorporation,
no holder may own, or be deemed to own by virtue of certain attribution
provisions of the Code, more than (A) 5% of the issued and outstanding shares of
Common Stock (the 'Common Stock Ownership Limit') and/or (B) more than 5% of any
class or series of Preferred Stock. (This limit, in addition to the Existing
Holder Limit, the Special Shareholder Limit, and the Non U.S. Shareholder Limit,
all as defined below, are referred to collectively herein as the 'Ownership
Limits.') Existing Holders, including Clark Enterprises Inc., The Oliver Carr
Company, Oliver T. Carr, Jr., and A. James Clark, are not subject to the Common
Stock Ownership Limit, but they are subject to special ownership limitations
(the 'Existing Holder Limit'). Furthermore, SC-USREALTY and its affiliates are
not subject to the Common Stock Ownership Limit, but are subject to a special
ownership limit of 45% of the outstanding shares of Common Stock and 45% of the
outstanding shares of each class or series of preferred stock of the Company
(the 'Special Shareholder Limit'). Furthermore, all holders are prohibited from
acquiring any capital stock if such acquisition would cause five beneficial
owners of capital stock to beneficially own in the aggregate more than 50% in
value of the outstanding capital stock.

     In addition to the above restrictions on ownership of shares of capital
stock of the Company, in order to assist the Company in qualifying as a
'domestically controlled REIT,' the Articles of Incorporation contain certain
provisions preventing any Non-U.S. Shareholder (as defined below) (other than
SC-USREALTY and its affiliates) from acquiring additional shares of the
Company's capital stock if, as a result of such acquisition, the Company would
fail to qualify as a 'domestically controlled REIT' (computed assuming that
SC-USREALTY owns the maximum percentage of the Company's capital stock that it
is permitted to own under the Special Shareholder Limit) (the 'Non-U.S.
Shareholder Limit'). A Non-U.S. Shareholder is a nonresident alien individual,
foreign corporation, foreign partnership and any other foreign shareholder. For
a discussion of the taxation of a Non-U.S. Shareholder and the requirements for
the Company to qualify as a 'domestically controlled REIT,' see 'Federal Income
Tax Considerations--Taxation of Holders of Common Stock--Taxation of Non-U.S.
Shareholders.' The Company is unlikely to be able to advise a prospective
Non-U.S. Shareholder that its purchase of any shares of the Company's capital
stock would not violate this prohibition, thereby subjecting such prospective
Non-U.S. Shareholder to the adverse consequences described under '--Violation of
Ownership Limits' below. Accordingly, an acquisition of the Company's capital
stock would not likely be a suitable investment for Non-U.S. Shareholders other
than SC-USREALTY.

     The Board may increase the Ownership Limits from time to time, but may not
do so to the extent that, after giving effect to such increase, five beneficial
owners of shares of capital stock could beneficially

                                       26
<PAGE>
own in the aggregate more than 49.5% of the value of the Company's outstanding
shares of capital stock. The Board, in its sole discretion, may waive the
Ownership Limits with respect to a holder if such holder's ownership will not
then or in the future jeopardize the Company's status as a REIT.

     Violation of Ownership Limits. The Articles of Incorporation provide that,
if any holder of capital stock of the Company purports to transfer shares to a
person or there is a change in the capital structure of the Company and either
the transfer or the change in capital structure would result in the Company
failing to qualify as a REIT, or such transfer or the change in capital
structure would cause the transferee to hold shares in excess of the applicable
Ownership Limit (including the Non-U.S. Shareholder Limit), then the capital
stock being transferred (or in the case of an event other than a transfer, the
capital stock beneficially owned) that would cause one or more of the
restrictions on ownership or transfer to be violated will be automatically
transferred to a trust for the benefit of a designated charitable beneficiary.
The purported transferee of such shares shall have no right to receive dividends
or other distributions with respect to such shares and shall have no right to
vote such shares. Any dividends or other distributions paid to such purported
transferee prior to the discovery by the Company that the shares have been
transferred to a trust shall be paid upon demand to the trustee of the trust for
the benefit of the charitable beneficiary. The trustee of the trust will have
all rights to dividends with respect to the shares of capital stock held in
trust, which rights will be exercised for the exclusive benefit of the
charitable beneficiary. Any dividends or distributions paid over to the trustee
will be held in trust for the charitable beneficiary. The trustee shall
designate a transferee of such stock so long as such shares of stock would not
violate the Ownership Limitations in the hands of such designated transferee.
Upon the sale of such shares, the purported transferee shall receive the lesser
of (A) (i) the price per share such purported transferee paid for the capital
stock in the purported transfer that resulted in the transfer of shares of
capital stock to the trust, or (ii) if the transfer or other event that resulted
in the transfer of shares of capital stock to the trust was not a transaction in
which the purported record transferee of shares of capital stock gave full value
for such shares, a price per share equal to the market price on the date of the
purported transfer or other event that resulted in the transfer of the shares to
the trust, and (B) the price per share received by the trustee from the sale or
disposition of the shares held in the trust.

     All certificates representing Common Stock will bear a legend referring to
the restrictions described above.

     Every owner of more than 5% (or such lower percentage as required by the
Code or regulations thereunder) of the issued and outstanding shares of Common
Stock must file a written notice with the Company containing the information
specified in the Articles of Incorporation no later than December 31 of each
year. In addition, each stockholder shall upon demand be required to disclose to
the Company in writing such information as the Company may request in good faith
in order to determine the Company's status as a REIT.

REGISTRAR AND TRANSFER AGENT

     The Registrar and Transfer Agent for the Common Stock is BankBoston, N.A.

                                       27
<PAGE>
                      DESCRIPTION OF COMMON STOCK WARRANTS

     The Company may issue Common Stock Warrants for the purchase of Common
Stock. Common Stock Warrants may be issued independently or together with any
other Securities offered by any Prospectus Supplement and may be attached to or
separate from such Securities. Each series of Common Stock Warrants will be
issued under a separate warrant agreement (each, a 'Warrant Agreement') to be
entered into between the Company and a warrant agent specified in the applicable
Prospectus Supplement (the 'Warrant Agent'). The Warrant Agent will act solely
as an agent of the Company in connection with the Common Stock Warrants of such
series and will not assume any obligation or relationship of agency or trust for
or with any holders or beneficial owners of Common Stock Warrants. The following
sets forth certain general terms and provisions of the Common Stock Warrants
offered hereby. Further terms of the Common Stock Warrants and the applicable
Warrant Agreements will be set forth in the applicable Prospectus Supplement.

     The applicable Prospectus Supplement will describe the terms of the Common
Stock Warrants in respect of which this Prospectus is being delivered,
including, where applicable, the following: (1) the title of such Common Stock
Warrants; (2) the aggregate number of such Common Stock Warrants; (3) the price
or prices at which such Common Stock Warrants will be issued; (4) the
designation, number and terms of the shares of Common Stock purchasable upon
exercise of such Common Stock Warrants; (5) the designation and terms of the
other Securities offered thereby with which such Common Stock Warrants are
issued and the number of such Common Stock Warrants issued with each such
Security offered thereby; (6) the date, if any, on and after which such Common
Stock Warrants and the related Common Stock will be separately transferable; (7)
the price at which each of the shares of Common Stock purchasable upon exercise
of such Common Stock Warrants may be purchased; (8) the date on which the right
to exercise such Common Stock Warrants shall commence and the date on which such
right shall expire; (9) the minimum or maximum number of such Common Stock
Warrants which may be exercised at any one time; (10) information with respect
to book entry procedures, if any; (11) a discussion of certain federal income
tax considerations; and (12) any other terms of such Common Stock Warrants,
including terms, procedures and limitations relating to the exchange and
exercise of such Common Stock Warrants.

                        DESCRIPTION OF DEPOSITARY SHARES

GENERAL

     The Company may issue receipts ('Depositary Receipts') for Depositary
Shares, each of which will represent a fractional interest of a share of a
particular series of Preferred Stock, as specified in the applicable Prospectus
Supplement. Shares of Preferred Stock of each series represented by Depositary
Shares will be deposited under a separate deposit agreement (each, a 'Deposit
Agreement') among the Company, the depositary named therein (a 'Preferred Stock
Depositary') and the holders from time to time of the Depositary Receipts.
Subject to the terms of the applicable Deposit Agreement, each owner of a
Depositary Receipt will be entitled, in proportion to the fractional interest of
a share of a particular series of Preferred Stock represented by the Depositary
Shares evidenced by such Depositary Receipt, to all the rights and preferences
of the Preferred Stock represented by such Depositary Shares (including
dividend, voting, conversion, redemption and liquidation rights).

     The Depositary Shares will be evidenced by Depositary Receipts issued
pursuant to the applicable Deposit Agreement. Immediately following the issuance
and delivery of the Preferred Stock by the Company to a Preferred Stock
Depositary, the Company will cause such Preferred Stock Depositary to issue, on
behalf of the Company, the Depositary Receipts. Copies of the applicable form of
Deposit Agreement and Depositary Receipt may be obtained from the Company upon
request, and the statements made hereunder relating to Deposit Agreements and
the Depositary Receipts to be issued thereunder are summaries of certain
anticipated provisions thereof and do not purport to be complete and are subject
to,

                                       28
<PAGE>
and qualified in their entirety by reference to, all of the provisions of the
applicable Deposit Agreement and related Depositary Receipts.

DIVIDENDS AND OTHER DISTRIBUTIONS

     A Preferred Stock Depositary will be required to distribute all cash
dividends or other cash distributions received in respect of the applicable
Preferred Stock to the record holders of Depositary Receipts evidencing the
related Depositary Shares in proportion to the number of such Depositary
Receipts owned by such holders, subject to certain obligations of holders to
file proofs, certificates and other information and to pay certain charges and
expenses to such Preferred Stock Depositary.

     In the event of a distribution other than in cash, a Preferred Stock
Depositary will be required to distribute property received by it to the record
holders of Depositary Receipts entitled thereto, subject to certain obligations
of holders to file proofs, certificates and other information and to pay certain
charges and expenses to such Preferred Stock Depositary, unless such Preferred
Stock Depositary determines that it is not feasible to make such distribution,
in which case such Preferred Stock Depositary may, with the approval of the
Company, sell such property and distribute the net proceeds from such sale to
such holders.

     No distribution will be made in respect of any Depositary Share to the
extent that it represents any Preferred Stock which has been converted or
exchanged before the record date for such distribution.

WITHDRAWAL OF STOCK

     Upon surrender of the Depositary Receipts at the corporate trust office of
the applicable Preferred Stock Depositary (unless the related Depositary Shares
have previously been called for redemption or converted), the holders thereof
will be entitled to delivery at such office, to or upon each such holder's
order, of the number of whole or fractional shares of the applicable Preferred
Stock and any money or other property represented by the Depositary Shares
evidenced by such Depositary Receipts. Holders of Depositary Receipts will be
entitled to receive whole or fractional shares of the related Preferred Stock on
the basis of the proportion of Preferred Stock represented by each Depositary
Share as specified in the applicable Prospectus Supplement, but holders of such
shares of Preferred Stock will not thereafter be entitled to receive Depositary
Shares therefor. If the Depositary Receipts delivered by the holder evidence a
number of Depositary Shares in excess of the number of Depositary Shares
representing the number of shares of Preferred Stock to be withdrawn, the
applicable Preferred Stock Depositary will be required to deliver to such holder
at the same time a new Depositary Receipt evidencing such excess number of
Depositary Shares.

REDEMPTION OF DEPOSITARY SHARES

     Whenever the Company redeems shares of Preferred Stock held by a Preferred
Stock Depositary, such Preferred Stock Depositary will be required to redeem as
of the same redemption date the number of Depositary Shares representing shares
of the Preferred Stock so redeemed, provided the Company shall have paid in full
to such Preferred Stock Depositary the redemption price of the Preferred Stock
to be redeemed plus an amount equal to any accrued and unpaid dividends thereon
to the date fixed for redemption. The redemption price per Depositary Share will
be equal to the redemption price and any other amounts per share payable with
respect to the Preferred Stock. If fewer than all the Depositary Shares are to
be redeemed, the Depositary Shares to be redeemed will be selected pro rata (as
nearly as may be practicable without creating fractional Depositary Shares) or
by any other equitable method determined by the Company that preserves the REIT
status of the Company.

     From and after the date fixed for redemption, all dividends in respect of
the shares of Preferred Stock so called for redemption will cease to accrue, the
Depositary Shares so called for redemption will no longer be deemed to be
outstanding and all rights of the holders of the Depositary Receipts evidencing
the Depositary Shares so called for redemption will cease, except the right to
receive any moneys payable upon such redemption and any money or other property
to which the holders of such Depositary Receipts

                                       29
<PAGE>
were entitled upon such redemption upon surrender thereof to the applicable
Preferred Stock Depositary.

VOTING OF THE PREFERRED STOCK

     Upon receipt of notice of any meeting at which the holders of the
applicable Preferred Stock are entitled to vote, a Preferred Stock Depositary
will be required to mail the information contained in such notice of meeting to
the record holders of the Depositary Receipts evidencing the Depositary Shares
which represent such Preferred Stock. Each record holder of Depositary Receipts
evidencing Depositary Shares on the record date (which will be the same date as
the record date for the Preferred Stock) will be entitled to instruct such
Preferred Stock Depositary as to the exercise of the voting rights pertaining to
the amount of Preferred Stock represented by such holder's Depositary Shares.
Such Preferred Stock Depositary will be required to vote the amount of Preferred
Stock represented by such Depositary Shares in accordance with such
instructions, and the Company will agree to take all reasonable action which may
be deemed necessary by such Preferred Stock Depositary in order to enable such
Preferred Stock Depositary to do so. Such Preferred Stock Depositary will be
required to abstain from voting the amount of Preferred Stock represented by
such Depositary Shares to the extent it does not receive specific instructions
from the holders of Depositary Receipts evidencing such Depositary Shares. A
Preferred Stock Depositary will not be responsible for any failure to carry out
any instruction to vote, or for the manner or effect of any such vote made, as
long as any such action or non-action is in good faith and does not result from
negligence or willful misconduct of such Preferred Stock Depositary.

LIQUIDATION PREFERENCE

     In the event of the liquidation, dissolution or winding up of the Company,
whether voluntary or involuntary, the holders of each Depositary Receipt will be
entitled to the fraction of the liquidation preference accorded each share of
Preferred Stock represented by the Depositary Share evidenced by such Depositary
Receipt, as set forth in the applicable Prospectus Supplement.

CONVERSION OF PREFERRED STOCK

     The Depositary Shares, as such, will not be convertible into Common Stock
or any other securities or property of the Company. Nevertheless, if so
specified in the applicable Prospectus Supplement relating to an offering of
Depositary Shares, the Depositary Receipts may be surrendered by holders thereof
to the applicable Preferred Stock Depositary with written instructions to such
Preferred Stock Depositary to instruct the Company to cause conversion of the
Preferred Stock represented by the Depositary Shares evidenced by such
Depositary Receipts into whole shares of Common Stock, other shares of Preferred
Stock of the Company or other shares of stock, and the Company will agree that
upon receipt of such instructions and any amounts payable in respect thereof, it
will cause the conversion thereof utilizing the same procedures as those
provided for delivery of Preferred Stock to effect such conversion. If the
Depositary Shares evidenced by a Depositary Receipt are to be converted in part
only, a new Depositary Receipt or Receipts will be issued for any Depositary
Shares not to be converted. No fractional shares of Common Stock will be issued
upon conversion, and if such conversion will result in a fractional share being
issued, an amount will be paid in cash by the Company equal to the value of the
fractional interest based upon the closing price of the Common Stock on the last
business day prior to the conversion.

AMENDMENT AND TERMINATION OF A DEPOSIT AGREEMENT

     Any form of Depositary Receipt evidencing Depositary Shares which will
represent Preferred Stock and any provision of a Deposit Agreement will be
permitted at any time to be amended by agreement between the Company and the
applicable Preferred Stock Depositary. However, any amendment that materially
and adversely alters the rights of the holders of Depositary Receipts or that
would be materially and adversely inconsistent with the rights granted to the
holders of the related Preferred Stock will not be effective unless such
amendment has been approved by the existing holders of at least two-thirds of
the applicable Depositary Shares evidenced by the applicable Depositary Receipts
then outstanding. No amendment shall impair the right, subject to certain
anticipated exceptions in the Deposit Agreements, of any holders of Depositary
Receipts to surrender any Depositary Receipt with instructions to deliver to the

                                       30
<PAGE>
holder the related Preferred Stock and all money and other property, if any,
represented thereby, except in order to comply with law. Every holder of an
outstanding Depositary Receipt at the time any such amendment becomes effective
shall be deemed, by continuing to hold such Depositary Receipt, to consent and
agree to such amendment and to be bound by the applicable Deposit Agreement as
amended thereby.

     A Deposit Agreement will be permitted to be terminated by the Company upon
not less than 30 days' prior written notice to the applicable Preferred Stock
Depositary if (i) such termination is necessary to preserve the Company's status
as a REIT or (ii) a majority of each series of Preferred Stock affected by such
termination consents to such termination, whereupon such Preferred Stock
Depositary will be required to deliver or make available to each holder of
Depositary Receipts, upon surrender of the Depositary Receipts held by such
holder, such number of whole or fractional shares of Preferred Stock as are
represented by the Depositary Shares evidenced by such Depositary Receipts
together with any other property held by such Preferred Stock Depositary with
respect to such Depositary Receipts. The Company will agree that if a Deposit
Agreement is terminated to preserve the Company's status as a REIT, then the
Company will use its best efforts to list the Preferred Stock issued upon
surrender of the related Depositary Shares on a national securities exchange. In
addition, a Deposit Agreement will automatically terminate if (i) all
outstanding Depositary Shares thereunder shall have been redeemed, (ii) there
shall have been a final distribution in respect of the related Preferred Stock
in connection with any liquidation, dissolution or winding up of the Company and
such distribution shall have been distributed to the holders of Depositary
Receipts evidencing the Depositary Shares representing such Preferred Stock or
(iii) each share of the related Preferred Stock shall have been converted into
stock of the Company not so represented by Depositary Shares.

CHARGES OF A PREFERRED STOCK DEPOSITARY

     The Company will pay all transfer and other taxes and governmental charges
arising solely from the existence of a Deposit Agreement. In addition, the
Company will pay the fees and expenses of a Preferred Stock Depositary in
connection with the performance of its duties under a Deposit Agreement.
However, holders of Depositary Receipts will pay the fees and expenses of a
Preferred Stock Depositary for any duties requested by such holders to be
performed which are outside of those expressly provided for in the applicable
Deposit Agreement.

RESIGNATION AND REMOVAL OF DEPOSITARY

     A Preferred Stock Depositary will be permitted to resign at any time by
delivering to the Company notice of its election to do so, and the Company will
be permitted at any time to remove a Preferred Stock Depositary, any such
resignation or removal to take effect upon the appointment of a successor
Preferred Stock Depositary. A successor Preferred Stock Depositary will be
required to be appointed within 60 days after delivery of the notice of
resignation or removal and will be required to be a bank or trust company having
its principal office in the United States and having a combined capital and
surplus of at least $50,000,000.

MISCELLANEOUS

     A Preferred Stock Depositary will be required to forward to holders of
Depositary Receipts any reports and communications from the Company which are
received by such Preferred Stock Depositary with respect to the related
Preferred Stock.

     Neither a Preferred Stock Depositary nor the Company will be liable if it
is prevented from or delayed in, by law or any circumstances beyond its control,
performing its obligations under a Deposit Agreement. The obligations of the
Company and a Preferred Stock Depositary under a Deposit Agreement will be
limited to performing their duties thereunder in good faith and without
negligence (in the case of any action or inaction in the voting of Preferred
Stock represented by the applicable Depositary Shares), gross negligence or
willful misconduct, and neither the Company nor any applicable Preferred Stock
Depositary will be obligated to prosecute or defend any legal proceeding in
respect of any Depositary Receipts, Depositary Shares or shares of Preferred
Stock represented thereby unless satisfactory indemnity is furnished. The
Company and any Preferred Stock Depositary will be permitted to rely on

                                       31
<PAGE>
written advice of counsel or accountants, or information provided by persons
presenting shares of Preferred Stock represented thereby for deposit, holders of
Depositary Receipts or other persons believed in good faith to be competent to
give such information, and on documents believed in good faith to be genuine and
signed by a proper party.

     In the event a Preferred Stock Depositary shall receive conflicting claims,
requests or instructions from any holders of Depositary Receipts, on the one
hand, and the Company on the other hand, such Preferred Stock Depositary shall
be entitled to act on such claims, requests or instructions received from the
Company.

                             BOOK-ENTRY SECURITIES

     The Securities may be issued in whole or in part in book-entry form,
meaning that beneficial owners of the Securities will not receive certificates
representing their ownership interests in the Securities, except in the event
the book-entry system for the Securities is discontinued. If the Securities are
issued in book-entry form, they will be issued, the form of one or more global
securities (the 'Global Securities'), which 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 class or series of Securities issued in book-entry
form will be described in the applicable Prospectus Supplement relating to such
class or series.

                       FEDERAL INCOME TAX CONSIDERATIONS

GENERAL

     The following discussion summarizes the material federal income tax
considerations to a prospective holder of Common Stock. The following discussion
is for general information only, is not exhaustive of all possible tax
considerations and is not intended to be and should not be construed as tax
advice. For example, this summary does not give a detailed discussion of any
state, local or foreign tax considerations. In addition, this discussion is
intended to address only those federal income tax considerations that are
generally applicable for all Security holders in the Company. It does not
discuss all of the aspects of federal income taxation that may be relevant to a
prospective Security holder in light of his or her particular circumstances or
to certain types of Security holders who are subject to special treatment under
the federal income tax laws including, without limitation, insurance companies,
tax-exempt entities, financial institutions or broker-dealers, foreign
corporations and persons who are not citizens or residents of the United States.
If the Company offers one or more series of Preferred Stock, Depositary Shares,
Common Stock Warrants or Debt Securities, then there may be tax consequences for
the holders of such Securities not discussed herein. For a discussion of any
such additional consequences, see the applicable Prospectus Supplement.

     The information in this section is based on the Code (including the
provisions of the Taxpayer Relief Act of 1997 (the '1997 Act'), several of which
are described herein), current, temporary and proposed Treasury Regulations, the
legislative history of the Code, current administrative interpretations and
practices of the IRS (including its practices and policies as endorsed in
private letter rulings, which are not binding on the IRS except with respect to
the taxpayer that receives such a ruling), and court decisions, all as of the
date hereof. No assurance can be given that future legislation, Treasury
Regulations, administrative interpretations and court decisions will not
significantly change current law or adversely affect existing interpretations of
current law. Any such change could apply retroactively to transactions preceding
the date of the change. Except as described below in '--Requirements for
Qualification--Income Tests,' the Company has not received any rulings from the
IRS concerning the tax treatment of the Company. Thus no assurance can be
provided that the statements set forth herein (which do not bind the IRS or the
courts) will not be challenged by the IRS or will be sustained by a court if so
challenged.

     As used under this heading, the term 'Company' refers solely to CarrAmerica
Realty Corporation.

     EACH PROSPECTIVE PURCHASER IS ADVISED TO CONSULT WITH HIS OR HER OWN TAX
ADVISOR REGARDING THE SPECIFIC TAX CONSEQUENCES TO HIM OR HER OF THE PURCHASE,
OWNERSHIP AND SALE OF SECURITIES OF AN ENTITY ELECTING TO BE TAXED AS A REIT,
INCLUDING THE FEDERAL, STATE, LOCAL, FOREIGN AND OTHER TAX CONSEQUENCES OF SUCH
PURCHASE, OWNERSHIP, SALE AND ELECTION AND OF POTENTIAL CHANGES IN APPLICABLE
TAX LAWS.

TAXATION OF THE COMPANY

     General. The Company has elected to be taxed as a REIT under Sections 856
through 860 of the Code commencing with its taxable year ended December 31,
1993. The Company believes that it was organized and has operated in a manner so
as to qualify for taxation as a REIT under the Code, and the Company intends to
continue to operate in such a manner. No assurance, however, can be given that
the Company has operated in a manner so as to qualify as a REIT or that it will
continue to operate in such a manner in the future. Qualification and taxation
as a REIT depends upon the Company's ability to meet on a continuing basis
(through actual annual operating results, distribution levels and diversity of
stock ownership) the various qualification tests imposed under the Code on
REITs, some of which are summarized below. While the Company intends to operate
so that it qualifies as a RElT, given the highly complex nature of the rules
governing REITs, the ongoing importance of factual determinations, and the
possibility of future changes in circumstances of the Company, no assurance can
be given that the Company has satisfied or will continue to satisfy such tests.
See '--Failure to Qualify' below.

                                       33
<PAGE>
     The following is a general summary of the Code provisions that govern the
federal income tax treatment of a REIT and its shareholders. These provisions of
the Code are highly technical and complex. This summary is qualified in its
entirety by the applicable Code provisions, Treasury Regulations and
administrative and judicial interpretations thereof, all of which are subject to
change prospectively or retroactively.

     In any year in which the Company qualifies for taxation as a REIT, it
generally will not be subject to federal corporate income taxes on net income
that it distributes currently to shareholders. However, the Company will be
subject to federal income tax in the following circumstances. First, the Company
will be taxed at regular corporate rates on any undistributed REIT taxable
income, including undistributed net capital gains. Second, under certain
circumstances, the Company may be subject to the 'alternative minimum tax' on
any items of tax preference. Third, if the Company has (i) net income from the
sale or other disposition of certain 'foreclosure property' that is held
primarily for sale to customers in the ordinary course of business or (ii) other
nonqualifying income from foreclosure property, it will be subject to tax at the
highest corporate rate on such income. Fourth, if the Company has net income
from prohibited transactions (which are, in general, certain sales or other
dispositions of property (other than foreclosure property) held primarily for
sale to customers in the ordinary course of business), such income will be
subject to a 100% tax. Fifth, if the Company should fail to satisfy the 75%
gross income test or the 95% gross income test (discussed below), and
nonetheless should maintain its qualification as a REIT because certain other
requirements have been met, it will be subject to a 100% tax on the net income
attributable to the greater of either the amount by which it fails the 75% gross
income test or the amount by which it fails the 95% gross income test. Sixth, if
the Company should fail to distribute during each calendar year at least the sum
of (i) 85% of its REIT ordinary income for such year, (ii) 95% of its REIT
capital gain net income for such year, and (iii) any undistributed taxable
income from prior periods, it would be subject to a 4% excise tax on the excess
of such required distribution over the amounts actually distributed. Seventh, if
the Company acquires or has acquired any asset from a C corporation (i.e., a
corporation generally subject to full corporate-level tax) in a transaction in
which the basis of the asset in the acquiror's hands is determined by reference
to the basis of the asset (or any other asset) in the hands of the C corporation
and the acquiror recognizes gain on the disposition of such asset during the 10
year period beginning on the date on which such asset was acquired by it, then
to the extent of such asset's 'Built-In Gain' (i.e.,the excess of (a) the fair
market value of such asset at the time of the acquisition by the Company over
(b) the adjusted basis in such asset, determined as of the time of such
acquisition), such gain will be subject to tax at the highest regular corporate
rate applicable, pursuant to anticipated Treasury Regulations that have not yet
been promulgated. This result with respect to the recognition of Built-In Gain
assumes that the Company will make an election pursuant to IRS Notice 88-19 with
respect to any such acquisition.

     Requirements for Qualification. The Code defines a REIT as a corporation,
trust or association (1) that is managed by one or more trustees or directors,
(2) the beneficial ownership of which is evidenced by transferable shares of
stock, or by transferable certificates of beneficial interest, (3) that would be
taxable as a domestic corporation, but for Sections 856 through 859 of the Code,
(4) that is neither a financial institution nor an insurance company subject to
certain provisions of the Code, (5) the beneficial ownership of which is held by
100 or more persons, (6) that during the last half of each taxable year not more
than 50% in value of the outstanding stock of which is owned, directly or
indirectly, by five or fewer individuals (as defined in the Code to include
certain entities), and (7) that meets certain other tests, described below,
regarding the nature of its income and assets. The Code provides that conditions
(1) through (4), inclusive, must be met during the entire taxable year and that
condition (5) must be met during at least 335 days of a taxable year of 12
months, or during a proportionate part of a taxable year of less than 12 months.
The Company's Articles of Incorporation contain restrictions regarding the
transfer of its capital stock that are intended to assist the Company in
continuing to satisfy the stock ownership requirements described in conditions
(5) and (6). See 'Description of Common Stock--Restrictions on Transfer.'
Moreover, pursuant to the 1997 Act, for the Company's taxable years commencing
on or after January 1, 1998, if the Company complies with regulatory rules
pursuant to which it is required to send annual letters to holders of its
capital stock requesting information regarding the actual ownership of the

                                       34
<PAGE>
capital stock, and the Company does not know, or exercising reasonable diligence
would not have known, whether it failed to meet requirement (6) above, the
Company will be treated as having met the requirement.

     Income Tests. In order to maintain qualification as a REIT, the Company
must satisfy certain gross income requirements, which are applied on an annual
basis. First, at least 75% of the Company's gross income (excluding gross income
from prohibited transactions) for each taxable year must be derived directly or
indirectly from investments relating to real property or mortgages on real
property (including 'rents from real property' and, in certain circumstances,
interest) or from certain types of temporary investments. Second, at least 95%
of the Company's gross income (excluding gross income from prohibited
transactions) for each taxable year must be derived from the same items which
qualify under the 75% income test, and from dividends, interest and gain from
the sale or disposition of stock or securities, or from any combination of the
foregoing. For its taxable years ending on or before December 31, 1997, the
Company was subject to a third gross income test which required that short-term
gain from the sale or other disposition of stock or securities, gain from
prohibited transactions and gain on the sale or other disposition of real
property held for less than four years (apart from involuntary conversions and
sales of foreclosure property) must have represented less than 30% of the
Company's gross income (including gross income from prohibited transactions).
Pursuant to the 1997 Act, the Company will not have to meet the 30% test for its
taxable years commencing on or after January 1, 1998.

     Rents received by the Company will qualify as 'rents from real property' in
satisfying the gross income requirements for a REIT described above only if
several conditions (related to the identity of the tenant, the computation of
the rent payable, and the nature of the property leased) are met. The Company
does not anticipate receiving rents that fail to meet these conditions in an
amount that reasonably could be expected to cause it to fail to meet the 75% and
95% gross income tests. In addition, for rents received to qualify as 'rents
from real property,' the Company generally must not operate or manage the
property or furnish or render services to tenants, other than through an
'independent contractor' from whom the Company derives no revenue. The
'independent contractor' requirement, however, does not apply to the extent the
services are 'usually or customarily rendered' in connection with the rental
space for occupancy only and are not otherwise considered 'rendered to the
occupant' ('Permissible Services'). The Company will provide certain services
with respect to the properties through entities that do not satisfy the
'independent contractor' requirements described above. The Company has received
a ruling from the IRS that the provision of certain services will not cause the
rents received with respect to the properties to fail to qualify as 'rents from
real property.' Based upon the IRS ruling and its experience in the office
rental markets in which the Company's properties are located, the Company
believes that all services provided to tenants will be considered 'usually or
customarily rendered' in connection with the rental of office space for
occupancy only, although there can be no assurance that the IRS will not contend
otherwise. If the Company contemplates providing services, either directly or
through another entity, in the future that reasonably might be expected not to
meet the 'usual or customary' standard, it will arrange to have such services
provided by an independent contractor from which the Company will receive no
income.

     Pursuant to the 1997 Act, for the Company's taxable years commencing on or
after January 1, 1998, rents received generally will qualify as rents from real
property notwithstanding the fact that the Company provides services that are
not Permissible Services so long as the amount received for such services meets
a de minimis standard. The amount received for 'impermissible services' with
respect to a property will be de minimis so long as such amount does not exceed
one percent of all amounts received, directly or indirectly, by the Company with
respect to such property. The amount that the Company will be deemed to have
received for performing 'impermissible services' will be the greater of the
actual amount so received or 150% of the direct cost to the Company of providing
such 'impermissible services.'

     The Company may receive fees in consideration of the performance of
management and administrative services with respect to properties that are not
owned entirely by the Company. A portion of such management and administrative
fees (corresponding to that portion of a property owned by a third party)
generally will not qualify under the 75% or 95% gross income tests. The Company
also may

                                       35
<PAGE>
receive other types of income with respect to the properties that it owns that
will not qualify for the 75% or 95% gross income tests. The Company believes,
however, that the aggregate amount of such fees and other non-qualifying income
in any taxable year will not cause the Company to exceed the limits on
non-qualifying income under the 75% and 95% gross income tests.

     If the Company fails to satisfy one or both of the 75% or 95% gross income
tests for any taxable year, it may nevertheless qualify as a REIT for such year
if it is entitled to relief under certain provisions of the Code. It is not
possible, however, to state whether in all circumstances the Company would be
entitled to the benefit of these relief provisions. Even if these relief
provisions were to apply, however, a 100% tax would be imposed with respect to
the 'excess net income' attributable to the failure to satisfy the 75% and 95%
gross income tests.

     Asset Tests. At the close of each quarter of its taxable year, the Company
also must satisfy the following three tests relating to the nature of its
assets: (i) at least 75% of the value of the Company's total assets must be
represented by 'real estate assets,' cash, cash items and government securities;
(ii) not more than 25% of the Company's total assets may be represented by
securities other than those in the 75% asset class; and (iii) of the investments
included in the 25% asset class, the value of any one issuer's securities (other
than an interest in a partnership, shares of a 'qualified REIT subsidiary' or
another REIT, but including any unsecured debt of Carr Realty, L.P. or
CarrAmerica Realty, L.P.) owned by the Company may not exceed 5% of the value of
the Company's total assets, and the Company may not own more than 10% of any one
issuer's outstanding voting securities (other than an interest in a partnership,
shares of a 'qualified REIT subsidiary' or another REIT). The Company owns
directly all of the non-voting stock, representing 95% of the equity, of
OmniOffices and CarrAmerica Development. By virtue of its ownership of CRLP
Units, the Company will be considered to own its pro rata share of the assets of
Carr Realty, L.P., including the securities of Carr Services, Inc. (Carr
Services, Inc., OmniOffices and CarrAmerica Development are referred to
collectively herein as the 'Non-qualified REIT Subsidiaries.') Neither Carr
Realty, L.P., CarrAmerica Realty, L.P., nor the Company will own more than 10%
of the voting securities of any Non-qualified REIT Subsidiary. There can be no
assurance, however, that the IRS might not contend that the arrangements between
the Company and the Non-qualified REIT Subsidiaries are such that the Company
should be considered to own more than 10% of the voting securities of one or
both of these entities. In addition, the Company and its senior management
believe that the Company's pro rata share of the value of the securities of each
such Non-qualified REIT Subsidiary and of any unsecured debt of Carr Realty,
L.P. and CarrAmerica Realty, L.P. owned by the Company will not exceed 5% of the
total value of the Company's assets. There can be no assurance, however, that
the IRS might not contend otherwise. Although the Company plans to take steps to
ensure that it continues to satisfy the 5% test, there can be no assurance that
such steps will be successful or will not require a reduction in the Company's
overall interest in one or more of the Non-qualified REIT Subsidiaries.

     Annual Distribution Requirements. The Company, in order to qualify as a
REIT, is required to distribute dividends (other than capital gain dividends) to
its shareholders in an amount at least equal to (i) the sum of (a) 95% of the
Company's 'REIT taxable income' (computed without regard to the dividends paid
deduction and the Company's net capital gain) and (b) 95% of the net income
(after tax), if any, from foreclosure property, minus (ii) the sum of certain
items of noncash income. In addition, if the Company disposes of any Built-In
Gain Asset during its Recognition Period, the Company will be required, pursuant
to Treasury Regulations which have not yet been promulgated, to distribute at
least 95% of the Built-In Gain (after tax), if any, recognized on the
disposition of such asset. See '--General' above for a discussion of 'Built-In
Gain Assets.' Such distributions must be paid in the taxable year to which they
relate, or in the following taxable year if declared before the Company timely
files its tax return for such year and if paid on or before the first regular
dividend payment date after such declaration.

     To the extent that the Company does not distribute all of its net capital
gain or distributes at least 95%, but less than 100%, of its 'REIT taxable
income,' as adjusted, it will be subject to tax thereon at regular ordinary and
capital gain corporate tax rates. The Company may elect to require the
shareholders to include the Company's undistributed net capital gains in their
income by designating, in a written

                                       36
<PAGE>
notice to shareholders, those amounts as undistributed capital gains in respect
of its shareholders' shares. If the Company makes such an election, the
shareholders will (i) include in their income as capital gains their
proportionate share of such undistributed capital gains and (ii) be deemed to
have paid their proportionate share of the tax paid by the Company on such
undistributed capital gains and thereby receive a credit or refund for such
amount. A shareholder will increase the basis in its Common Shares by the
difference between the amount of capital gain included in its income and the
amount of the tax that the Company is deemed to have paid on the shareholder's
behalf. The earnings and profits of the Company will be adjusted appropriately.
For a more detailed description of the tax consequences to a shareholder of such
a designation, see '--Taxation of Holders of Common or Preferred Stock.'

     In addition, if the Company should fail to distribute during each calendar
year at least the sum of (i) 85% of its REIT ordinary income for such year, (ii)
95% of its REIT capital gain income for such year, and (iii) any undistributed
taxable income from prior periods, the Company would be subject to a 4% excise
tax on the excess of such required distribution over the sum of amounts actually
distributed during the calendar year by the REIT and the amount, if any, on
which the REIT paid income tax for such year.

     The Company intends to make timely distributions sufficient to satisfy its
annual distribution requirements. It is expected that the Company's REIT taxable
income will be less than its cash flow due to the allowance of depreciation and
other noncash charges in computing REIT taxable income. Accordingly, the Company
anticipates that it will generally have sufficient cash or liquid assets to
enable it to satisfy the distribution requirements described above. It is
possible, however, that the Company, from time to time, may not have sufficient
cash or other liquid assets to meet these distribution requirements due to
timing differences between (i) the actual receipt of income and actual payment
of deductible expenses and (ii) the inclusion of such income and deduction of
such expenses in arriving at taxable income of the Company. If such timing
differences occur, in order to meet the distribution requirements, the Company
may find it necessary to arrange for short-term, or possibly long-term,
borrowings or to pay dividends in the form of taxable stock dividends.

     Under certain circumstances, the Company may be able to rectify a failure
to meet the distribution requirement for a year by paying 'deficiency dividends'
to shareholders in a later year, which may be included in the Company's
deduction for dividends paid for the earlier year. Thus, the Company may be able
to avoid being taxed on amounts distributed as deficiency dividends; however,
the Company will be required to pay interest based upon the amount of any
deduction taken for deficiency dividends.

     Failure to Qualify. If the Company fails to qualify for taxation as a REIT
in any taxable year, the Company will be subject to tax (including any
applicable alternative minimum tax) on its taxable income at regular corporate
rates. Distributions to shareholders in a year in which the Company fails to
qualify as a REIT will not be deductible and will not be required to be made. In
addition, if the Company fails to qualify as a REIT, all distributions to
shareholders will be taxable as ordinary income, to the extent of the Company's
current and accumulated earnings and profits, and, subject to certain
limitations of the Code, corporate distributees may be eligible for the
dividends received deduction. Unless entitled to relief under specific statutory
provisions, the Company also will be disqualified from taxation as a REIT for
the four taxable years following the year during which qualification was lost.
It is not possible to state whether in all circumstances the Company would be
entitled to such statutory relief.

TAXATION OF HOLDERS OF COMMON OR PREFERRED STOCK

     Taxation of Taxable U.S. Shareholders. As used herein, the term 'U.S.
shareholder' means a holder of Common or Preferred Stock who (for United States
federal income tax purposes) (i) is a citizen or resident of the United States,
(ii) is a corporation, partnership, or other entity treated as a corporation or
partnership for federal income tax purposes created or organized in or under the
laws of the United States or of any political subdivision thereof, (iii) is an
estate the income of which is subject to United States federal income taxation
regardless of its source or (iv) a trust whose administration is subject to the
primary supervision of a United States court and which has one or more United
States persons who have the authority to control all substantial decisions of
the trust.

                                       37
<PAGE>
     As long as the Company qualifies as a REIT, distributions made to the
Company's taxable U.S. shareholders out of current or accumulated earnings and
profits (and not designated as capital gain dividends) will be taken into
account by them as ordinary income, and corporate shareholders will not be
eligible for the dividends received deduction as to such amounts. For purposes
of determining whether distributions on the shares of Common Stock are out of
current or accumulated earnings and profits, the earnings and profits of the
Company will be allocated first to shares of Preferred Stock and second to the
shares of Common Stock. There can be no assurance that the Company will have
sufficient earnings and profits to cover distributions on any shares of
Preferred Stock.

     Distributions that are designated as capital gain dividends will be taxed
as gains from the sale or exchange of a capital asset held for more than one
year (to the extent they do not exceed the Company's actual net capital gain for
the taxable year) without regard to the period for which the shareholder has
held its stock. Corporate shareholders, however, may be required to treat up to
20% of certain capital gain dividends as ordinary income.

     As described below in '--Recent Legislation,' the 1997 Act changed
significantly the taxation of capital gains by taxpayers who are individuals,
estates, or trusts. On November 10, 1997, the IRS issued IRS Notice 97-64, which
provides generally that the Company may classify portions of its designated
capital gain dividend as (i) a 20% rate gain distribution (which would be taxed
as long-term capital gain in the 20% group), (ii) an unrecaptured Section 1250
gain distribution (which would be taxed as long-term capital gain in the 25%
group), or (iii) a 28% rate gain distribution (which would be taxed as long-term
capital gain in the 28% group). (If no designation is made, the entire
designated capital gain dividend will be treated as a 28% rate gain
distribution.) IRS Notice 97-64 provides that a REIT must determine the maximum
amounts that it may designate as 20% and 25% rate capital gain dividends by
performing the computation required by the Code as if the REIT were an
individual whose ordinary income were subject to a marginal tax rate of at least
28%. The Notice further provides that designations made by the REIT will be
effective only to the extent that they comply with Revenue Ruling 89-81, which
requires that distributions made to different classes of shares not be composed
disproportionately of dividends of a particular type.

     Distributions in excess of current or accumulated earnings and profits will
not be taxable to a U.S. shareholder to the extent that they do not exceed the
adjusted basis of the shareholder's shares of Common Stock, but rather will
reduce the adjusted basis of such shares of Common Stock. To the extent that
such distributions exceed the adjusted basis of a U.S. shareholder's shares of
Common Stock, they will be included in income as capital gains, assuming the
shares of Common Stock are a capital asset in the hands of the U.S. shareholder.

     In general, a domestic shareholder will realize capital gain or loss on the
disposition of shares of Common Stock equal to the difference between (i) the
amount of cash and the fair market value of any property received on such
disposition and (ii) the shareholder's adjusted basis of such shares of Common
Stock. With respect to dispositions occurring after July 28, 1997, in the case
of a taxable U.S. shareholder who is an individual or an estate or trust, such
gain or loss will be long-term capital gain or loss, subject to a 28% tax rate,
if such shares have been held for more than one year but not more than 18 months
and long-term capital gain or loss, subject to a 20% tax rate, if such shares
have been held for more than 18 months. In the case of a taxable U.S.
shareholder that is a corporation, such gain or loss will be long-term capital
gain or loss if such shares have been held for more than one year. Loss upon a
sale or exchange of shares of Common Stock by a shareholder who has held such
shares of Common Stock for six months or less (after applying certain holding
period rules) will be treated as a long-term capital loss to the extent of
distributions from the Company required to be treated by such shareholder as
long-term capital gain.

     Pursuant to the 1997 Act, for the Company's taxable years commencing on or
after January 1, 1998, the Company may elect to require the holders of Common
Stock to include the Company's undistributed net long-term capital gains in
their income. If the Company makes such an election, the holders of Common Stock
will (i) include in their income as long-term capital gains their proportionate
share of such undistributed capital gains and (ii) be deemed to have paid their
proportionate share of the tax paid by

                                       38
<PAGE>
the Company on such undistributed capital gains and thereby receive a credit or
refund for such amount. A holder of Common Stock will increase the basis in its
Common Stock by the difference between the amount of capital gain included in
its income and the amount of the tax it is deemed to have paid. The earnings and
profits of the Company will be adjusted appropriately. As described below in
'--Recent Legislation,' with respect to such long-term capital gain of a taxable
domestic shareholder that is an individual or an estate or trust, the IRS has
authority to issue regulations that could apply the special tax rate applicable
to sales of depreciable real property by an individual or an estate or trust to
the portion of the long-term capital gains of an individual or an estate or
trust attributable to deductions for depreciation taken with respect to
depreciable real property.

     Backup Withholding. The Company will report to its domestic shareholders
and the IRS the amount of dividends paid during each calendar year, and the
amount of tax withheld, if any, with respect thereto. Under the backup
withholding rules, a shareholder may be subject to backup withholding at the
rate of 31% with respect to dividends paid unless such holder (a) is a
corporation or comes within certain other exempt categories and, when required,
demonstrates this fact, or (b) provides a taxpayer identification number and
certifies as to no loss of exemption from backup withholding. Amounts withheld
as backup withholding will be creditable against the stockholder's income tax
liability. In addition, the Company may be required to withhold a portion of
capital gain distributions made to any shareholders who fail to certify their
non-foreign status to the Company. See '--Taxation of Non-U.S. Shareholders'
below. Additional issues may arise pertaining to information reporting and
backup withholding with respect to Non-U.S. Shareholders (persons other than (i)
citizens or residents of the United States, (ii) corporations, partnerships or
other entities created or organized under the laws of the United States or any
political subdivision thereof, and (iii) estates or trusts the income of which
is subject to United States federal income taxation regardless of its source)
and Non-U.S. Shareholders should consult their tax advisors with respect to any
such information reporting and backup withholding requirements.

     The Treasury Department has recently finalized regulations regarding the
withholding and information reporting rules discussed above. In general, these
regulations do not alter the substantive withholding and information reporting
requirements but unify current certification procedures and forms and clarify
and modify reliance standards. These regulations (as modified by a notice
published by the IRS) generally are effective for payments made after December
31, 1999, subject to certain transition rules. Valid withholding certificates
that are held on December 31, 1999, will remain valid until the earlier of
December 31, 2000 or the date of expiration of the certificate under rules
currently in effect (unless otherwise invalidated due to changes in the
circumstances of the person whose name is on such certificate).

     Taxation of Tax-Exempt Shareholders. As a general rule, amounts distributed
to a tax-exempt entity do not constitute 'unrelated business taxable income'
('UBTI'), and thus distributions by the Company to a stockholder that is a
tax-exempt entity should also not constitute UBTI, provided that the tax-exempt
entity has not financed the acquisition of its shares of Common Stock with
'acquisition indebtedness' within the meaning of the Code and the shares of
Common Stock are not otherwise used in an unrelated trade or business of the
tax-exempt entity. However, distributions by a REIT to a tax-exempt employee's
pension trust that owns more than 10% of the REIT will be treated as UBTI in an
amount equal to the percentage of gross income of the REIT that is derived from
an 'unrelated trade or business' (determined as if the REIT were a pension
trust) divided by the gross income of the REIT for the year in which the
dividends are paid. This rule only applies, however, if (i) the percentage of
gross income of the REIT that is derived from an unrelated trade or business for
the year in which the dividends are paid is at least 5%, (ii) the REIT qualifies
as a REIT only because the pension trust is not treated as a single individual
for purposes of the 'five-or-fewer rule' (see '--Taxation of the
Company-Requirements for Qualification' above), and (iii) (A) one pension trust
owns more than 25 percent of the value of the REIT or, (B) a group of pension
trusts individually holding more than 10 percent of the value of the REIT
collectively own more than 50 percent of the value of the REIT. The Company
currently does not expect that this rule will apply.

                                       39
<PAGE>
     Taxation of Non-U.S. Shareholders. The rules governing U.S. federal income
taxation of the ownership and disposition of Common Stock by persons that are,
for purposes of such taxation, nonresident alien individuals, foreign
corporations, foreign partnerships, or foreign estates or trusts (collectively,
'Non-U.S. Shareholders') are complex, and no attempt will be made herein to
provide more than a limited summary of such rules. Prospective Non-U.S.
Shareholders should consult with their own tax advisors to determine the impact
of U.S. federal, state and local income tax laws with regard to an investment in
Common Stock, including any reporting requirements.

     Distributions that are not attributable to gain from sales or exchanges by
the Company of U.S. real property interests and not designated by the Company as
capital gain dividends will be treated as dividends of ordinary income to the
extent that they are made out of current or accumulated earnings and profits of
the Company. Such distributions, ordinarily, will be subject to a withholding
tax equal to 30% of the gross amount of the distribution unless an applicable
tax treaty reduces that tax. Distributions in excess of current and accumulated
earnings and profits of the Company will not be taxable to a Non-U.S.
Shareholder to the extent that they do not exceed the adjusted basis of the
shareholder's Common Stock, but rather will reduce the adjusted basis of such
Common Stock. To the extent that such distributions exceed the adjusted basis of
a Non-U.S. Shareholder's Common Stock, they will give rise to tax liability if
the Non-U.S. Shareholder would otherwise be subject to tax on any gain from the
sale or disposition of its Common Stock as described below. For withholding tax
purposes, the Company is currently required to treat all distributions as if
made out of its current or accumulated earnings and profits and thus intends to
withhold at the rate of 30% (or a reduced treaty rate if applicable) on the
amount of any distribution (other than distributions designed as capital gain
dividends) made to a Non-U.S. Shareholder. Under the final regulations
(discussed above), generally effective for distributions on or after January 1,
2000, the Company would not be required to withhold at the 30% rate on
distributions it reasonably estimates to be in excess of the Company's current
and accumulated earnings and profits. If it cannot be determined at the time a
distribution is made whether such distribution will be in excess of current and
accumulated earnings and profits, the distribution will be subject to
withholding at the rate applicable to ordinary dividends. As a result of a
legislative change made by the Small Business Job Protection Act of 1996, it
appears that the Company will be required to withhold 10% of any distribution in
excess of the Company's current and accumulated earnings and profits.
Consequently, although the Company intends to withhold at a rate of 30% on the
entire amount of any distribution (or a lower applicable treaty rate), to the
extent that the Company does not do so, any portion of a distribution not
subject to withholding at a rate of 30% (or a lower applicable treaty rate) will
be subject to withholding at a rate of 10%. However, the Non-U.S. Shareholder
may seek from the IRS a refund of such amounts from the IRS if it is
subsequently determined that such distribution was, in fact, in excess of
current or accumulated earnings and profits of the Company, and the amount
withheld exceeded the Non-U.S. Shareholder's United States tax liability, if
any.

     For any year in which the Company qualifies as a REIT, distributions that
are attributable to gain from sales or exchanges by the Company of U.S. real
property interests will be taxed to a Non-U.S. Shareholder under the provisions
of the Foreign Investment in Real Property Tax Act of 1980 ('FIRPTA') at the
normal capital gain rates applicable to domestic shareholders (subject to
applicable alternative minimum tax and a special alternative minimum tax in the
case of nonresident alien individuals). Also, distributions subject to FIRPTA
may be subject to a 30% branch profits tax in the hands of a corporate Non-U.S.
Shareholder not entitled to treaty relief or exemption. The Company is required
by applicable Treasury Regulations to withhold 35% of any distribution that is
or could be designated by the Company as a capital gain dividend. The amount
withheld is creditable against the Non-U.S. Shareholder's FIRPTA tax liability.

     Although the law is not entirely clear on the matter, it appears that
amounts designated by the Company pursuant to the 1997 Act as undistributed
capital gains in respect of shares of Common Stock (see 'Taxation of
Shareholders--Taxation of Taxable Domestic Shareholders' above) would be treated
with respect to Non-U.S. Shareholders in the manner outlined in the preceding
paragraph for actual distributions by the Company of capital gain dividends.
Under that approach, the Non-U.S. Shareholders would be able to offset as a
credit against their United States federal income tax liability resulting

                                       40
<PAGE>
therefrom their proportionate share of the tax paid by the Company on such
undistributed capital gains (and to receive from the IRS a refund to the extent
their proportionate share of such tax paid by the Company were to exceed their
actual United States federal income tax liability).

     Gain recognized by a Non-U.S. Shareholder upon a sale of Common Stock
generally will not be taxed under FIRPTA if the Company is a 'domestically
controlled REIT,' defined generally as a REIT in which at all times during a
specified testing period less than 50% in value of the stock was held directly
or indirectly by foreign persons. As of April 13, 1998, SC-USREALTY held
approximately 40.0% in value of the outstanding Common Stock of the Company. In
the event that SC-USREALTY and other stockholders of the Company who are
Non-U.S. Shareholders own collectively 50% or more, in value, of the outstanding
stock of the Company, the Company would cease to be a 'domestically controlled
REIT.'

     If the Company does not qualify as a 'domestically controlled REIT,' a
Non-U.S. Shareholder's sale of securities of the Company generally still will
not be subject to U.S. tax under FIRPTA as a sale of a U.S. real property
interest, provided that (i) the securities are 'regularly traded' (as defined by
the applicable Treasury Regulations) on an established securities market, and
(ii) the selling Non-U.S. Shareholder held 5% or less of the value of any class
or series of the Company's outstanding securities at all times during a
specified testing period. The Company believes that the Common Stock would be
considered to be 'regularly traded' for this purpose, and the Company has no
actual knowledge of any Non-U.S. Shareholder (other than SC-USREALTY) that holds
in excess of 5% of the Company's capital stock. In order to assist the Company
in qualifying as a 'domestically controlled REIT,' the Articles of Incorporation
contain certain provisions preventing any Non-U.S. Shareholder (other than
SC-USREALTY and its affiliates) from acquiring additional shares of the
Company's capital stock if, as a result of such acquisition, the Company would
fail to qualify as a 'domestically controlled REIT' (computed assuming that
SC-USREALTY owns the maximum percentage of the Company's capital stock that
SC-USREALTY is permitted to own under the Special Shareholder Limit). The
Company is unlikely to be able to advise a prospective Non-U.S. Shareholder that
its purchase of any shares of the Company's capital stock would not violate this
prohibition, thereby subjecting such prospective Non-U.S. Shareholder to the
adverse consequences described under 'Description of Common Stock--Restrictions
on Transfer--Violation of Ownership Limits.' Accordingly, an acquisition of the
Company's capital stock would not likely be a suitable investment for Non-U.S.
Shareholders other than SC-USREALTY.

     If the gain on the sale of Common Stock were to be subject to tax under
FIRPTA, the Non-U.S. Shareholder would be subject to the same treatment as
domestic shareholders with respect to such gain (subject to applicable
alternative minimum tax and a special alternative minimum tax in the case of
nonresident alien individuals), and the purchaser of the Common Stock would be
required to withhold and remit to the IRS 10% of the purchase price.

RECENT LEGISLATION

     As described above, 1997 Act contains certain changes to the REIT
qualification requirements and to the taxation of REITs. The 1997 Act also
contains certain changes to the taxation of capital gains of individuals, trusts
and estates.

     Capital Gain Rates. Subject to certain exceptions, for individuals, trusts
and estates the maximum rate of tax on the net capital gain from a sale or
exchange occurring after July 28, 1997 of a capital asset held for more than 18
months has been reduced from 28% to 20%. The maximum rate has been reduced to
18% for capital assets acquired after December 21, 2000 and held for more than
five years. The maximum rate for capital assets held for more than one year but
not more than 18 months remains at 28%. The maximum rate for net capital gains
attributable to the sale of depreciable real property held for more than 18
months in 25% to the extent of the prior deductions for 'unrecaptured Section
1250 gain' (i.e., depreciation deductions not otherwise recaptured as ordinary
income under the existing depreciation recapture rules). Capital gain from the
sale of depreciable real property held for more than 18 months allocated by the
Company to a non-corporate shareholder will be subject to the 25% rate to the
extent that the capital gain on the real property sold by the Company does not
exceed prior depreciation deductions with respect to such property. The 1997 Act
provides the IRS with authority to issue

                                       41
<PAGE>
regulations that could, among other things, apply these rates on a look-through
basis in the case of 'pass-through' entities such as the Company. The taxation
of capital gains of corporations was not changed by the 1997 Act.

     REIT Provisions. In addition to the provisions discussed above, the 1997
Act contains a number of technical provisions that either (i) reduce the risk
that the Company will inadvertently cease to qualify as a REIT, or (ii) provide
additional flexibility with which the Company can meet the REIT qualification
requirements. These provisions are effective for the Company's taxable years
commencing on or after January 1, 1998.

OTHER TAX CONSIDERATIONS

     Entity Classification. A significant number of the Company's investments
are through Carr Realty, L.P. and CarrAmerica Realty, L.P. If either Carr
Realty, L.P. or CarrAmerica Realty, L.P. were treated as an association, the
entity would be taxable as a corporation and therefore would be subject to an
entity level tax on its income. In such a situation, the character of the
Company's assets and items of gross income would change and would preclude the
Company from qualifying as a REIT (see 'Taxation of the Company--Income Tests'
and '--Asset Tests').

     Prior to January 1, 1997, an organization formed as a partnership or a
limited liability company was treated as a partnership for federal income tax
purposes rather than as a corporation only if it had no more than two of the
four corporate characteristics that the Treasury Regulations in effect at that
time used to distinguish a partnership from a corporation for tax purposes.
These four characteristics were (i) continuity of life, (ii) centralization of
management, (iii) limited liability and (iv) free transferability of interests.
Under final Treasury Regulations which became effective January 1, 1997, the
four factor test has been eliminated and an entity formed as a partnership or as
a limited liability company will be taxed as a partnership for federal income
tax purposes, unless it specifically elects otherwise. The Regulations provide
that the IRS will not challenge the classification of an existing partnership or
limited liability company for tax periods prior to January 1, 1997, so long as
(1) the entity had a reasonable basis for its claimed classification, (2) the
entity and all of its members recognized the federal income tax consequences of
any changes in the entity's classification within the 60 months prior to January
1, 1997, and (3) neither the entity nor any member of the entity had been
notified in writing on or before May 8, 1996, that the classification of the
entity was under examination by the IRS.

     The Company believes that Carr Realty, L.P. and CarrAmerica Realty, L.P.
each will be treated as a partnership for federal income tax purposes (and not
as an association taxable as a corporation).

     Tax Allocations with Respect to the Properties. When property is
contributed to a partnership in exchange for an interest in the partnership, the
partnership generally takes a carryover basis in that property for tax purposes
equal to the adjusted basis of the contributing partner in the property, rather
than a basis equal to the fair market value of the property at the time of
contribution (this difference is referred to as 'Book-Tax Difference'). The
partnership agreements of each of Carr Realty, L.P. and CarrAmerica Realty, L.P.
require that allocations of income, gain, loss and deduction with respect to
each property contributed to those partnerships be made in a manner consistent
with the special rules in 704(c) of the Code and the regulations thereunder,
which will tend to eliminate the Book-Tax Differences with respect to such
contributed properties over the life of the partnership. However, because of
certain technical limitations, the special allocation rules of Section 704(c)
may not always entirely eliminate the Book-Tax Difference on an annual basis or
with respect to a specific taxable transaction such as a sale. Thus, the
carryover basis of such contributed properties in the hands of Carr Realty, L.P.
or CarrAmerica Realty, L.P., as applicable could cause the Company to be
allocated lower amounts of depreciation and other deductions for tax purposes
than would be allocated to the Company if all such contributed properties were
to have a tax basis equal to their fair market values at the time such
properties were contributed to Carr Realty, L.P. or CarrAmerica Realty, L.P., as
applicable. The foregoing rules also apply for purposes of determining the
Company's earnings and profits. The application of such rules over time could
result in a higher portion of distributions to shareholders being taxed as
dividends. See '--Taxation of Holders of Common Stock.'

                                       42
<PAGE>
     Non-Qualified REIT Subsidiaries. The Non-qualified REIT Subsidiaries do not
qualify as REITs and thus pay federal, state and local income taxes (including
District of Columbia franchise tax) on their net income at normal corporate
rates. To the extent the Non-qualified REIT Subsidiaries are required to pay
federal, state and local income taxes, the cash available for distribution to
stockholders will be reduced accordingly.

     State and Local Taxes; District of Columbia Unincorporated Business Tax.
The Company and its stockholders may be subject to state or local taxation in
various state or local jurisdictions, including those in which it or they
transact business or reside. The state and local tax treatment of the Company
and its stockholders may not conform to the federal income tax consequences
discussed above. In this regard, the District of Columbia imposes an
unincorporated business income tax, at the rate of 9.975%, on the 'District of
Columbia taxable income' of partnerships doing business in the District of
Columbia. Because many of the properties owned by Carr Realty, L.P. are located
in the District of Columbia, the Company's share of the 'District of Columbia
taxable income' of Carr Realty, L.P. will be subject to this tax. Carr Realty,
L.P. has taken steps to attempt to reduce the amount of income that is
considered 'District of Columbia taxable income,' but it is likely that at least
some portion of the income attributable to Carr Realty, L.P.'s properties
located in the District of Columbia will be subject to the District of Columbia
tax. To the extent Carr Realty, L.P. is required to pay the District of Columbia
unincorporated business income tax, the cash available for distribution to the
Company and, therefore, to its stockholders as dividends will be reduced
accordingly. This tax would not apply if the Company were to own and operate its
assets directly, rather than through Carr Realty, L.P.; however, the Company's
ability to eliminate Carr Realty, L.P. and thus own directly the assets
currently owned by Carr Realty, L.P. is severely limited.

                              PLAN OF DISTRIBUTION

GENERAL

     The Company may sell Securities in or through underwriters for public offer
and sale by them, and also may sell Securities offered hereby to investors
directly or through agents. Any such underwriter or agent involved in the offer
and sale of the Securities will be named in the applicable Prospectus
Supplement.

     Underwriters may offer and sell the Securities at a fixed price or prices,
which may be changed, at prices related to the prevailing market prices at the
time of sale or at negotiated prices. The Company also may, from time to time,
authorize underwriters acting as the Company's agents to offer and sell
Securities upon terms and conditions set forth in the applicable Prospectus
Supplement. In connection with the sale of the Securities, underwriters may be
deemed to have received compensation from the Company in the form of
underwriting discounts or commissions and may also receive commissions from
purchasers of the Securities for whom they may act as agent. Underwriters may
sell Securities to or through dealers, and such dealers may receive compensation
in the form of discounts, concessions or commissions from the underwriters
and/or commissions from the purchasers for whom they may act as agent.


     Any underwriting compensation paid by the Company to underwriters or agents
in connection with the offering of the Securities, and any discounts,
concessions or commissions allowed by underwriters to participating dealers,
will be set forth in the applicable Prospectus Supplement. Underwriters, dealers
and agents participating in the distribution of the Securities may be deemed to
be underwriters, and any discounts and commissions received by them and any
profit realized by them on resale of the Securities may be deemed to be
underwriting discounts and commissions under the Securities Act. Underwriters,
dealers and agents may be entitled, under agreements with the Company, to
indemnification against and contribution toward certain civil liabilities,
including liabilities under the Securities Act.


     If so indicated in the applicable Prospectus Supplement, the Company will
authorize underwriters or other persons acting as the Company's agents to
solicit offers by certain institutions to purchase

                                       43
<PAGE>
Securities from the Company at the public offering price set forth in such
Prospectus Supplement pursuant to delayed delivery contracts ('Contracts')
providing for payment and delivery on the date or dates stated in such
Prospectus Supplement. Each Contract will be for an amount not less than, and
the aggregate principal amount of Securities sold pursuant to Contracts shall be
neither less nor more than, the respective amounts stated in the applicable
Prospectus Supplement. Institutions with whom Contracts, when authorized, may be
made include commercial and savings banks, insurance companies, pension funds,
investment companies, educational and charitable institutions, and other
institutions, but will in all cases be subject to the approval of the Company.
Contracts will not be subject to any conditions except (i) the purchase by an
institution of the Securities covered by its Contracts shall not at the time of
delivery be prohibited under the laws of any jurisdiction in the United States
to which such institution is subject, and (ii) if the Securities are being sold
to underwriters, the Company shall have sold to such underwriters the total
principal amount of the Securities less the principal amount thereof covered by
Contracts.

     Certain of the underwriters and their affiliates may be customers of,
engage in transactions with and perform services for the Company and its
Subsidiaries in the ordinary course of business.

PARTICIPATION RIGHTS

     In conjunction with the SC-USREALTY Transaction, so long as SC-USREALTY
owns at least 25% of the outstanding Common Stock of the Company on a fully
diluted basis, SC-USREALTY will be entitled (except in certain limited
circumstances), upon compliance with certain specified conditions, to a
participation right to purchase or subscribe for, either as part of such
issuance or in a concurrent issuance, a total number of shares of Common Stock
or Preferred Stock, as the case may be, equal to up to 30% (or 35% in certain
circumstances) of the total number of shares or of Common Stock or Preferred
Stock, as applicable, proposed to be issued by the Company. All purchases
pursuant to such participation rights will be at the same price and on the same
terms and conditions as are applicable to other purchasers hereunder.

RESALES

     If set forth in the applicable Prospectus Supplement, this Prospectus may
be used in connection with resales or redistributions of shares of the Company
by a selling stockholder. The selling stockholder may be a person who acquired
the shares from the Company or such a person's pledgees, transferees or other
successors in interest. Such a resale or redistribution may be effected directly
or indirectly through brokers or dealers or in a distribution by one or more
underwriters on a firm commitment or best efforts basis, on the NYSE, in the
over-the-counter market, on any other national securities exchange on which
shares of the Company's Common Stock are listed or traded, in privately
negotiated transactions or otherwise, at market prices prevailing at the time of
sale, at prices related to such prevailing market prices or at negotiated
prices. Such a resale or redistribution also may be effected through a block
trade (which may involve cross trades) in which the broker or dealer engaged
will attempt to sell the shares as agent but may position and resell a portion
of the block as principal to facilitate the transaction; purchases by a broker
or dealer as principal and resale by such broker or dealer for its account;
exchange distributions and/or secondary distributions in accordance with the
rules of the NYSE; ordinary brokerage transactions and transactions in which the
broker solicits purchasers; an offering at other than a fixed price on or
through the facilities of the NYSE or to or through a market maker otherwise
than on the NYSE; sales to a dividend reinvestment plan established by the
Company, or to any agent acting on behalf of such plan, for sale to participants
in the plan; pledges to lenders as collateral to secure loans, credit or other
financing arrangements and any subsequent foreclosure thereunder; and any other
legally available means. In effecting sales, brokers or dealers engaged by the
Selling Stockholder may arrange for other brokers or dealers to participate. Any
public offering price and any discount or concessions allowed or reallowed or
paid to dealers may be changed from time to time. The Selling Stockholder may
from time to time deliver all or a portion of the shares of Common Stock covered
by a particular Prospectus Supplement to cover a short sale or sales or upon the
exercise, settlement or closing of a call equivalent position or a put
equivalent position. The broker-dealers participating in such a resale or
redistribution may be deemed 'underwriters' within the meaning of the Securities
Act, and any profit on the sale of the shares of Common Stock and any
commissions received by any such broker-dealers may be regarded as underwriting
commissions under the Securities Act. Selling stockholders, underwriters,
dealers and agents may be entitled, under agreements with the Company, to
indemnification against and contribution toward certain civil liabilities,
including liabilities under the Securities Act. The shares of Common Stock may
be sold from time to time at varying prices determined at the time of sale or at
negotiated prices.

     The Company will pay all expenses in connection with the registration of
such resales and redistributions. The selling stockholder will pay any brokerage
or underwriting commissions and taxes of any kind (including, without
limitation, transfer taxes).


                                       44
<PAGE>

     In connection with resales and redistributions, the following information
will, to the extent then required, be provided in the applicable Prospectus
Supplement: the number of shares to be sold, the purchase price, the public
offering price, if applicable, the name of any underwriter, agent or
broker-dealer, and any applicable commissions, discounts or other items
constituting compensation to underwriters, agents or broker-dealers with respect
to the particular sale or distribution.

     The rules of the SEC permit an underwriter to engage in certain
transactions that stabilize the price of shares of the Company's Common Stock in
connection with resales or redistributions of the Company's comomon shares. Such
transactions may consist of bids or purchases for the purpose of pegging, fixing
or maintaining the market price of the shares being sold.

     If an underwriter creates a short position in shares of the Company's
Common Stock in connection with a resale or redistribution, i.e., if it sells
more shares than are set forth on the cover page of the applicable Prospectus
Supplement, the underwriter may reduce that short position by purchasing shares
of the Company's Common Stock in the open market.

     In the case of an underwritten resale of shares, the managing underwriter
may also impose a penalty bid on certain underwriters and selling group members.
This means that, if the managing underwriter purchases shares in the open market
to reduce any underwriter's short position, or to stabilize the price of the
Company's common shares, the managing underwriter may reclaim the amount of the
selling concession from any such underwriters and selling group members who sold
those shares.

     In general, purchases of a security for the purpose of stablization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of a security to the extent that it
discourages resales of the security.

                                 LEGAL MATTERS

     The legality of the Debt Securities, the Preferred Stock, the Depositary
Shares, the Common Stock and the Common Stock Warrants offered hereby have been
passed upon for the Company by Hogan & Hartson L.L.P., Washington, D.C. Certain
federal income tax matters have been passed upon for the Company by Hogan &
Hartson L.L.P., Washington, D.C.

Item 15.  Indemnification of Directors and Officers

         The Company's officers and directors are and will be indemnified under
Maryland and Delaware law, the charter and by-laws of the Company, the
partnership agreement of Carr Realty, L.P. and the partnership agreement of
CarrAmerica Realty, L.P.

         The charter and by-laws of the Company require that the Company shall,
to the fullest extent permitted by Section 2-418 of the Maryland General
Corporation Law (the "MGCL") as in effect from time to time, indemnify any
person who is or was, or is the personal representative of a deceased person who
was, a director or officer of the Company against any judgments, penalties,
fines, settlements and reasonable expenses and any other liabilities; provided,
that, unless applicable law otherwise requires, indemnification shall be
contingent upon a determination, by the Board by a majority vote of a quorum
consisting of directors not, at the time, parties to the proceeding, or, if such
a quorum cannot be obtained, then by a majority vote of a committee of the Board
consisting solely of two or more directors not, at the time, parties to such
proceeding and who were duly designated to act in the matter by a majority vote
of the full Board in which the designated directors who are parties may
participate or by special legal counsel selected by and if directed by the Board
as set forth above, that indemnification is proper in the circumstances because
such director, officer, employee, or agent has met the applicable standard of
conduct prescribed by Section 2-418(b) of the MGCL.

         Under Maryland law, a corporation formed in Maryland is permitted to
limit, by provision in its charter, the liability of directors and officers so
that no director or officer of the Company shall be liable to the Company or to
any shareholder for money damages except to the extent that (i) the director or
officer actually received an improper benefit in money, property or services,
for the amount of the benefit or profit in money, property or services actually
received, or (ii) a judgment or other final adjudication adverse to the director
or officer is entered in a proceeding based on a finding in a proceeding that
the director's or officer's action was the result of active and deliberate
dishonesty and was material to the cause of action adjudicated in the
proceeding.

         The partnership agreements of Carr Realty, L.P. and CarrAmerica Realty,
L.P. also provide for indemnification of the Company and their officers and
directors against any and all losses, claims, damages, liabilities, joint or
several, expenses (including legal fees and expenses), judgments, fines,
settlements, and other amounts arising from any and all claims, demands,
actions, suits or proceedings, civil, criminal, administrative or investigative,
that relate to the operations of the partnership as set forth in the partnership
agreements in which any indemnitee may be involved, or is threatened to be
involved,

                                      II-1


<PAGE>


unless it is established that (i) the act or mission of the indemnitee was
material to the matter giving rise to the proceeding and either was committed in
bad faith or was the result of active and deliberate dishonesty, (ii) the
indemnitee actually received an improper personal benefit in money, property or
services, or (iii) in the case of a criminal proceeding, the indemnitee had
cause to believe that the act or omission was unlawful. The termination of any
proceeding by judgment, order or settlement does not create a presumption that
the indemnitee did not meet the requisite standard of conduct set forth in the
respective partnership agreement section on indemnification. The termination of
any proceeding by conviction or upon a plea of nolo contendere or its
equivalent, or an entry of an order of probation prior to judgment creates a
rebuttable presumption that the indemnitee acted in a manner contrary to that
specified in the indemnification section of the partnership agreements. Any
indemnification pursuant to one of the partnership agreements may only be made
out of the assets of that respective partnership.

Item 16.  Exhibits



     The exhibits to this registration statement are listed in the Exhibit
Index, which appears after the signature page and is incorporated in this Item
16 by reference.


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:

                  (i)      To include any prospectus required by Section
                           10(a)(3) of the Securities Act of 1933;

                  (ii)     To reflect in the prospectus any facts or events
                           arising after the effective date of the registration
                           statement (or the most recent post-effective
                           amendment thereof) which, individually or in the
                           aggregate, represent a fundamental change in the



                                      II-2
<PAGE>

                           information set forth in the registration statement.
                           Notwithstanding the foregoing, any increase or
                           decrease in volume of securities offered (if the
                           total dollar value of securities offered would not
                           exceed that which was registered) and any deviation
                           from the low or high end of the estimated maximum
                           offering range may be reflected in the form of
                           prospectus filed with the Commission pursuant to Rule
                           424(b) if, in the aggregate, the changes in volume
                           and price represent no more than a 20 percent change
                           in the maximum aggregate offering price set forth in
                           the "Calculation of Registration Fee" table in the
                           effective registration statement; and

                  (iii)    To include any material information with respect to
                           the plan of distribution not previously disclosed in
                           the registration statement or any material change to
                           such information in this registration statement;

         provided, however, that subparagraphs (i) and (ii) above do not apply
         if the registration statement is on Form S-3, Form S-8 or Form F-3, and
         the information required to be included in a post-effective amendment
         by those paragraphs is contained in periodic reports filed with or
         furnished to the Commission by the registrant pursuant to Section 13 or
         Section 15(d) of the Securities Exchange Act of 1934 that are
         incorporated by reference in this registration statement.

         (2) That, for the purpose of determining any liability under the
         Securities Act of 1933, each such post-effective amendment shall be
         deemed to be a new registration statement relating to the Offered
         Securities offered herein, and the offering of such Offered Securities
         at that time shall be deemed to be the initial bona fide offering
         thereof.

         (3) To remove from registration by means of a post-effective amendment
         any of the Offered Securities being registered which remain unsold at
         the termination of the offering.

         The undersigned registrant hereby undertakes that, for the 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 the
Securities Exchange Act of 1934 that is incorporated by reference in this
registration statement shall be deemed to be a new registration statement
relating to the Offered Securities offered therein, and the offering of such
Offered 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 existing provisions or otherwise, the registrant has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
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 Act and will be governed by the final adjudication of
such issue.

                Any certificate or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon an Opinion of Counsel, or a
certificate or representations 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
Company stating that the information as to such factual matters is in the
possession of the Company, 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 of the Outstanding Securities of
all series or one or more series, as the case may be, 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 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 Company. 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 conclusive
in favor of the Trustee and the Company and any agent of the Trustee or the
Company, 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 by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other reasonable manner which the Trustee deems sufficient.

                (c) The ownership of Registered Securities shall be proved by
the Security Register.



                                      -13-
<PAGE>


                (d) The ownership of Bearer Securities 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, wherever
situated, if such certificate shall be deemed by 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 Company 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 of Bearer
Securities may also be proved in any other manner which the Trustee deems
sufficient.

                (e) If the Company shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may, at its option, in or pursuant to a Board
Resolution, fix in advance a record date for the determination of Holders
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so.
Notwithstanding TIA Section 316(c), such record date shall be the record date
specified in or pursuant to such Board Resolution, which shall be a date not
earlier than the date 30 days prior to the first solicitation of Holders
generally in connection therewith and not later than the date such solicitation
is completed. 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 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 Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

                SECTION 105. Notices, etc., to Trustee and Company. 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,

                (1) the Trustee by any Holder or by the Company 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

                (2) the Company 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 Company
addressed to it at the address of its principal office specified in the first
paragraph of this Indenture or at any other address previously furnished in
writing to the Trustee by the Company.

                SECTION 106. Notice to Holders; Waiver. Where this Indenture
provides for notice of any event to Holders of Registered Securities by the
Company 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
The City of New York 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
or waiver required or permitted under this Indenture shall be in the English
language, except that 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 notice. Waivers of notice by Holders shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

                SECTION 107. Effect of Headings and Table of Contents. The
Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

                SECTION 108. Successors and Assigns. All covenants and
agreements in this Indenture by the Company shall be binding on their successors
and assigns, whether so expressed or not.

                SECTION 109. Separability Clause. In case any provision in this
Indenture or in any Security or coupon shall be 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,
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. No Personal Liability. 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 indebtedness
evidenced thereby, shall be had against any promoter, as such, or against any
past, present or future shareholder, officer or director, as such, of the
Company or of any successor, either directly or through the Company 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.

                SECTION 112. Governing Law. This Indenture and the Securities
and coupons shall be governed by and construed in accordance with the law of the
State of ____________.

                SECTION 113. 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 shall not be a Business Day at any Place of
Payment, then (notwithstanding any other provision of this Indenture or any
Security or coupon other than a provision in the Securities of any series which
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, but may
be made 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, 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, as the case may
be.

                                     [BANK], as Trustee                       
                                                                              
                                                                              
                                                                              
                                                                              
                                     By:_____________________________________ 
                                             Authorized Signatory             
                                                                              
                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 (8) 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 shall represent the aggregate amount of Outstanding Securities
of such series from time to time endorsed thereon and 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 by the
Trustee in such manner and upon instructions given by such Person or Persons as
shall be specified therein or in the Company Order to be delivered to the
Trustee 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 Company Order. If a
Company Order pursuant to Section 303 or 304 has been, or simultaneously is,
delivered, any instructions by the Company 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 Company and the Company 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 any Security in 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 Company, the Trustee and any agent of
the Company and the Trustee shall treat as the Holder of such principal amount
of Outstanding Securities represented by a permanent global Security (i) in the
case of a permanent global Security in registered form, the Holder of such
permanent global Security in registered form, or (ii) in the case of a permanent
global Security in bearer form, Euroclear or CEDEL.

manner in which, any interest payable on a temporary global Security on an
Interest Payment Date will be paid if other than in the manner provided in

                (19) the applicability, if any, of Sections 1402 and/or 1403 to

                (22) whether and under what circumstances the Company will pay

the case of Registered Securities, as to denomination and except as may
otherwise be provided in or pursuant to such Board Resolution (subject to
Section 303) and set forth in such Officers' Certificate or in any such
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

                SECTION 302. Denominations. The Securities of each series shall
be issuable in such denominations as shall be specified as contemplated by
Section 301. With respect to Securities of any series denominated in Dollars, in
the absence of any such provisions with respect to the Securities of any series,
the Registered Securities of such series, 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 of such series, other than Bearer Securities issued in global form
(which may be of any denomination), shall be issuable in a denomination of
$5,000.

                SECTION 303. Execution, Authentication, Delivery and Dating. The
Securities and any coupons appertaining thereto shall be executed by the
Company's Chairman of the Board, Chief Financial Officer, President, Secretary
or one of its Executive Vice Presidents. 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 Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and
delivery of such Securities 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 Company may deliver Securities of any series,
together with any coupon appertaining thereto, executed by the Company to the
Trustee for authentication, together with a Company Order for the authentication
and delivery of such Securities, and the Trustee in accordance with the Company
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, 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
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 Company 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,

                (i) an Opinion of Counsel complying with Section 102 and stating
that

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



                                      -21-
<PAGE>



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

                (c) such Securities, together with any coupons appertaining
thereto, when completed by appropriate insertions and executed and delivered by
the Company 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 Company in the manner and subject to any conditions specified in
such Opinion of Counsel, will constitute legal, valid and binding obligations of
the Company, 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

                (ii) 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, that 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 a Company 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.

                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 Company, and the Company 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
Company, 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 Company may execute, and upon
Company 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. In the case of Securities of
any series, such temporary Securities may be in global form.


                                      -22-
<PAGE>



                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 Company 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 Company 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 non-matured coupons appertaining thereto), the Company 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 Section 303.
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. 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 Company shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary global Security, executed by the Company. On or after
the Exchange Date, such temporary global Security shall be surrendered by the
Common Depositary to the Trustee, as the Company'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 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



                                      -23-
<PAGE>


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 the Trustee prior to the expiration of two years after such Interest
Payment Date in order to be repaid to the Company.

                SECTION 305. Registration, Registration of Transfer and
Exchange. The Company shall cause to be kept at the Corporate Trust Office of
the Trustee or in any office or agency of the Company 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 Company 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 Company 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 initially appointed
"Security Registrar" for the purpose of registering Registered Securities and
transfers of Registered Securities on such Security Register as herein provided.
In the event that 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 Company in a Place of Payment for that series, the
Company 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.

                Subject to the provisions of this Section 305, at the option of
the Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series, of any authorized denomination or
denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be
exchanged at any such office or agency. Whenever any such Registered Securities
are so surrendered for exchange, the Company 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 Company 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 Company 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 Company 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 definitive



                                      -25-
<PAGE>



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 selected or approved by the Company or to a nominee of such
successor to DTC. If at any time DTC notifies the Company 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 Company
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 Company within 90 days after the Company 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 Company,
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 Company 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. 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 date on which such interest may be so exchanged, the
Company 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 Company Order with respect thereto to
the Trustee, as the Company'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 Company, 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 Company or the Security Registrar) be duly endorsed, or be accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar, duly executed by the Holder thereof or his attorney duly
authorized in writing.


                                      -26-
<PAGE>



                No service charge shall be made for any registration of transfer
or exchange of Securities, but the Company 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 Section 304, 906, 1107 or 1305 not involving any
transfer.

                The Company, the Trustee or the Security Registrar, 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 Company, together with, in appropriate
cases, such security or indemnity as may be required by the Company or the
Trustee to hold each of them or any agent of either of them harmless, the
Company 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 Company 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 hold each of them and any agent of either of them harmless, then, in the
absence of notice to the Company or the Trustee that such Security or coupon has
been acquired by a bona fide purchaser, the Company shall execute and upon the
Company's 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 immediately preceding 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 Company 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), any 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 on Bearer Securities shall be payable only upon presentation and
surrender of the coupons appertaining thereto.


                                      -27-
<PAGE>



                Upon the issuance of any new Security under this Section, the
Company 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 Company, 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 hereunder.

                The provisions of this Section 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 Preserved.
Except as otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 301, interest on 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
Company maintained for such purpose pursuant to Section 1002; provided, however,
that each installment of interest on any Registered Security may at the
Company'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.

<PAGE>



                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 Company at its election in each case,
as provided in clause (1) or (2) below:

                (1) The Company 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 Company 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 Company 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 in this clause provided. 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 Company of such Special Record Date and, in the name and at the
expense of the Company, 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 Company, 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 therefor 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 (2). 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.

                (2) The Company 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 Company 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 Company, the Trustee and
any agent of the Company 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, such Registered Security and
for all other purposes whatsoever, whether or not such Registered Security be
overdue, and none of the Company, the Trustee or any agent of the Company 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 Company, the Trustee and any agent of the
Company 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 payment thereof or on account thereof and for all other
purposes whatsoever, whether or not such Security or coupon be overdue, and none
of the Company, the Trustee or any agent of the Company or the Trustee shall be
affected by notice to the contrary.

                None of the Company, 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 Company, the Trustee, or any agent of
the Company, 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. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company 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 Company
has not issued and sold, and all Securities so delivered shall be promptly
canceled by the Trustee. If the Company 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 destroyed by the Trustee and
the Trustee shall deliver a certificate of such destruction to the Company,
unless, by the Company Order, the Company 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 of each series 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 Company Request cease to be of further effect with respect
to any series of Securities specified in such Company 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 a
Company Order, and at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture as to
such series when,

appertaining to Bearer Securities surrendered for exchange for Registered

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 Company and thereafter repaid to the Company
or discharged from such trust (as provided in Section 1003) have been delivered
to the Trustee for cancellation; or

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

                               (i) have become due and payable, or

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

                               (iii) if redeemable at the option of the Company,
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 Company,

and the Company, in the case of (i), (ii) or (iii) above, has irrevocably
deposited or caused to be deposited with the Trustee as trust funds in trust for
the 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;

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

                (3) the Company 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 Company to the Trustee and any predecessor
Trustee under Section 606, the obligations of the Company 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 deposited with the

accordance with the provisions of the Securities, the coupons and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company 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 deposited with or received by the Trustee, but such money
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):

                (1) 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, Additional Amounts or coupon
becomes due and payable, and continuance of such default for a period of 30
days; or

                (2) 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, upon redemption, upon declaration or otherwise; or

                (3) (i) default in the performance, or breach, of any covenant
or warranty of the Company in this Indenture with respect to any Security of
that series (other than a covenant or warranty a default in whose performance or
whose breach is elsewhere in this Section specifically dealt with), or (ii) the
failure of any Subsidiary to comply with the provisions in Section 1004, and, in
each case, continuance of such default or breach for a period of 60 days after
there has been given, by registered or certified mail to the Company, by the
Trustee or to the Company 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

                (4) default under any bond, debenture, note or other evidence of
indebtedness for money borrowed by the Company or any of its Subsidiaries
(including obligations under leases required to be capitalized on the balance
sheet of the lessee under GAAP), representing Recourse Indebtedness or
indebtedness guaranteed by such party in an aggregate principal amount in excess
of $5,000,000, 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 the Company or any of its Subsidiaries (including the leases)
in an aggregate principal amount in excess of $5,000,000, whether the
indebtedness now exists or shall hereafter be created, which default shall have
resulted in the indebtedness becoming or being declared due and payable prior to
the date on which it would otherwise have become due and payable, or the
obligations being accelerated, without the acceleration having been rescinded or
annulled;


                                      -32-
<PAGE>



                (5) the Company or any Significant Subsidiary pursuant to or
within the meaning of any Bankruptcy Law:

                    (A) commences a voluntary case,

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

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

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

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

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

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

                    (C) orders the liquidation of the Company or any Significant
                        Subsidiary,

and the order or decree remains unstayed and in effect for 90 days;
or

                (7) any other Event of Default provided 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 in every such case the Trustee or the
Holders of not 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, and premium or Make-Whole Amount,
if any, on all the Securities of that series to be due and payable immediately,
by a notice in writing to the Company (and to the Trustee if given by the
Holders), and upon any such declaration such principal, and premium and
Make-Whole Amount (if any), or specified portion thereof shall become
immediately due and payable. If an Event of Default with respect to the
Securities of any series set forth in Section 501(5) or (6) of this Indenture
occurs and is continuing, then in every such case all the Securities of that
series shall become immediately due and payable, without notice to the Company,
at the principal amount thereof plus accrued interest to the date the Securities
of that series are paid plus any Make-Whole Amount due on the Securities of that
series.

                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 a majority in principal
amount of the Outstanding Securities of that series, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequences if:



                                      -33-
<PAGE>


                (1) the Company has paid or deposited with the Trustee a sum
sufficient to pay in the currency, 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):

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

                       (B) 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 at the
rate or rates borne by or provided for in such Securities,

                       (C) to the extent that payment of such interest 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

                       (D) 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

                (2) 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 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 Company covenants that if:

                (1) 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

                (2) 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 upon redemption, upon dedication or otherwise, then the Company 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 Amount, 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 Company 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 Company, or any other obligor upon such Securities
of such series and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or any other obligor
upon such Securities of such series, wherever situated.

<PAGE>



                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 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 Company or any other obligor upon the Securities or
the property of the Company 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 Company for the payment of overdue principal, premium or Make-Whole Amount,
if any, or interest) shall be entitled and empowered, by intervention in such
proceeding or otherwise:

                (i) 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 to file such other papers or
                documents as may be necessary or advisable in order to have the
                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

                (ii) to collect and receive any moneys or 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 Securities of such series or 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.

                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 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: To the payment of the remainder, if any, to the Company.

                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:

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

                (2) 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;

                (3) 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;

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

                (5) 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 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
due dates expressed in such Security or coupon (or, in the case of redemption,
on the Redemption 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.


                                      -36-
<PAGE>



                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 Company, 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 the
Holders 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 the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders 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, provided that

                (1) such direction shall not be in conflict with any rule of law
or with this Indenture,

                (2) the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction, and

                (3) 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



                                      -37-
<PAGE>



                (1) 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

                (2) 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, any
Event of Default arising therefrom shall be deemed to have been cured, and for
every purpose of this Indenture, the Company, Trustee and Holders shall be
restored to their former positions and rights hereunder; 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
Company 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 Company (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 10% 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 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). The Company agrees to pay or reimburse the Trustee for paying
all reasonable costs and expenses (including reasonable counsels' fees) of the
Trustee in connection with (a) any default and any enforcement or collection
proceedings resulting therefrom and (b) the enforcement of this Section 515.


                                   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, 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; 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 a committee of trust


                                      -38-
<PAGE>



officers of the Trustee in good faith determine that the withholding of such
notice is in the 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(3) 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):

                (1) except during the continuance of an Event of Default, the
Trustee shall 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;

                (2) in case a default or an Event of Default has occurred and is
continuing of which a Responsible Officer of the Trustee has actual knowledge or
of which written notice of such default or Event of Default shall have been
given to the Trustee by the Company, any other obligor of the Securities or by
any Holder, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent Person would exercise or use under the circumstances in
the conduct of his own affairs;

                (3) 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;

Board of Directors may be sufficiently evidenced by a Board Resolution;

                (5) 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;

                (6) 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

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 Company personally or by agent or attorney;

                (8) in the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the

                (9) the Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents or attorneys and the Trustee shall not be responsible for any misconduct
or negligence on the part of any agent or attorney appointed with due care by it
hereunder; and

                (10) no provision of this Indenture shall be construed to
relieve the Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that

                     (a) this paragraph (10) shall not be construed to limit the
     effect of paragraph (1) of this Section;

                     (b) the Trustee shall not be liable for any errors of
     judgment or any acts, omissions, mistakes of fact or law taken or omitted

     place of conducting any proceeding for any remedy available to the Trustee,
     or exercising any trust or power conferred upon the Trustee, under this
     Indenture; and

                     (d) no provision of this Indenture shall require the
     Trustee 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.

                (11) Whether nor not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section.

                The permissive right of the Trustee to do the things enumerated
in this Indenture shall not be construed as a duty, and the Trustee shall not be
answerable for other than its negligence or willful misconduct.

                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

of the Securities or coupons, except that the Trustee represents that it is duly

                SECTION 604. May Hold Securities. The Trustee, any Paying Agent,
Security Registrar, Authenticating Agent or any other agent of the Company, 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, may
otherwise deal with the Company with the same rights it would have if it were
not the Trustee, Paying Agent, Security Registrar, Authenticating Agent or such
other agent.

                SECTION 605. Money Held in Trust. 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 Company.

                SECTION 606. Compensation and Reimbursement. The Company agrees:

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

                (2) 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

                (3) 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(5) or Section
501(6), 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
Company under this Section, the Trustee shall have a lien prior to the Holders
of 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 on particular Securities or any coupons.

                Notwithstanding any provision in this Indenture, the Trustee's
right to immunities and protection from liability hereunder and its rights to
payment of its fees, expenses and indemnities shall survive its resignation or
removal and the final payment or defeasance of the Securities and the
termination of the Indenture and all indemnification and releases from liability
granted herein shall extend to its directors, officers, employees and agents.

                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 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
Company. If an 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.

                (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 the
Company.

                (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 Company or by any
Holder of a Security who has been a bona fide Holder of a Security for at least
six months, or

                     (2) the Trustee shall cease to be eligible under Section
607 and shall fail to resign after written request therefor by the Company 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 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, (i) the Company by or
pursuant to a Board Resolution may remove the Trustee and appoint a successor
Trustee with respect to all Securities, or (ii) 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 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 Company, 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).
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
Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance or such appointment, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders of Securities and accepted appointment in the manner hereinafter
provided, 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 Company 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 Company and 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 Company 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.

                (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 Company,
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 Trustees 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 Company, 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 Company
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 of 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 issued upon exchange, registration of transfer or
partial redemption or repayment thereof, except upon original issuance or in
replacement of mutilated, lost, stolen or destroyed Securities, 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 of which instrument shall
be promptly furnished to the Company. Except upon original issuance or in
replacement of mutilated, lost, stolen or destroyed Securities, wherever
reference is made in this Indenture to the authentication and delivery of
Securities by the Trustee or the Trustee's certificate 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 Company 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 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.


                                      -44-
<PAGE>



                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 Company. 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 the Company. 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 Company 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 Company 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.

                                       [BANK], as Trustee

and addresses of the Holders of Securities in accordance with TIA Section 312,
regardless of the source from which such information was derived, and that the
Trustee shall not be held accountable by reason of mailing any material pursuant
to a request made under TIA Section 312(b).

                SECTION 702. Reports by Trustee. Within 60 days after June 30 of
each year commencing with the first June 30 after the first issuance of

required to file the same with the Commission, copies of the annual reports and

any of the foregoing as the Commission may from time to time by rules and
regulations prescribe) which the Company may be required to file with the
Commission pursuant to Section 13 or Section 15(d) of the Exchange Act; or the
Company is not required to file information, documents or reports pursuant to

of this Section as may be required by rules and regulations prescribed from time
to time by the Commission.

Leases and Conveyances Permitted Subject to Certain Conditions. The Company may
consolidate with, or sell, lease or convey all or substantially all of its

executed and delivered to the Trustee by such entity and (ii) immediately after
giving effect to such transaction and treating any indebtedness which becomes an
obligation of the Company or any Subsidiary as a result thereof as having been
incurred by the Company or such Subsidiary at the time or such transaction, no
Event of Default, and no event which, after notice or the lapse of time, or
both, would become an Event of Default, shall have occurred and be continuing.

                SECTION 802. Rights and Duties of Successor Entity. In case of
any consolidation, merger, sale, lease or conveyance permitted under Section
801 and upon any assumption by the successor entity, such successor entity
shall succeed to and be substituted for the Company, with the same effect as if
it had been named herein as the Company, and the predecessor entity, except in
the event of a lease, shall be relieved of any further obligation under this
Indenture and the Securities. Such successor entity thereupon may cause to be
signed, and may issue either in its own name or in the name of the Company, any
or all of the Securities issuable hereunder which theretofore shall not have
been signed by the Company and delivered to the Trustee; and, upon the order of
such successor entity, instead of the Company, 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 Company to the Trustee for
authentication, and any Securities which such successor entity 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 from the Company with
respect to Section 801 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 entity, complies with the provisions of this Article
and that all conditions precedent herein provided for relating to such
transaction have been complied with.

                             SUPPLEMENTAL INDENTURES

                SECTION 901. Supplemental Indentures without Consent of Holders.
Without the consent of any Holders of Securities or coupons, the Company, when
authorized by or pursuant to a Board Resolution, and the Trustee, at any time
and from time to time, may enter into one or more indentures supplemental
hereto, in form satisfactory to the Trustee, for any of the following purposes:

                (1) to evidence the succession of another Person to the Company
and the assumption by any such successor of the covenants of the Company herein
and in the Securities contained; or

                (2) to add to the covenants of the Company for the benefit of
the Holders of all or any series of Securities (and if such covenants are to be
for the benefit of less than all series of Securities, stating that such
covenants are expressly being included solely for the benefit of such series) or
to surrender any right or power herein conferred upon the Company; or



                                      -47-
<PAGE>



                (3) 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

                (4) 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 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

                (5) to change or eliminate any of the provisions or 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

                (6) to secure the Securities; or

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

                (8) 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

                (9) 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; or

                (10) 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.

                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 Outstanding Securities affected by such supplemental indenture, by Act of
said Holders delivered to the Company and the Trustee, the Company, 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:


                                      -48-
<PAGE>



                (1) 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 payable in respect thereof, any Security; or reduce
the principal amount thereof or the rate or amount of interest thereon, or any
premium payable upon the redemption thereof, or change any obligation of the
Company to pay Additional Amounts pursuant to Section 1012 (except as
contemplated by Section 801(1) and permitted by Section 901(1)), or reduce the
amount of the principal of an Original Issue Discount Security or Make-Whole
Amount 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, any Security or any premium or Make-Whole
Amount or the interest thereon 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

                (2) 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

                (3) 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. In 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 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 and delivery 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 TIA. Every supplemental indenture
executed pursuant to this Article 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 Company shall so determine,
new Securities of any series so modified as to conform, in the opinion of the
Trustee and the Company, to any such supplemental indenture may be prepared and
executed by the Company 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 Company and the Trustee of any supplemental indenture
pursuant to the provisions of Section 902, the Company 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 (if any), Make-Whole
Amount (if any), Interest and Additional Amounts. The Company 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
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 Company, 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 Company 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 or
conversion, where Securities of that series may be surrendered for registration
of transfer or exchange and where notices and demands to or upon the Company 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 Company will
maintain: (A) in the Borough of Manhattan, The City of New York, an office or
agency where any Registered Securities of that series may be presented or
surrendered for payment or conversion, where any Registered 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



                                      -50-
<PAGE>


Company in respect of the Securities of that series and this Indenture may be
served and where Bearer Securities of that series and related coupons may be
presented or surrendered for payment or conversion 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) or conversion; 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 Company 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 Company in
respect of the Securities of that series and this Indenture may be served. The
Company 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
Company 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) or conversion at the offices specified in the Security, in London,
England, and the Company hereby appoint the same as its agent to receive such
respective presentations, surrenders, notices and demands, and the Company
hereby appoint 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 Company 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 the 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 Company's
Paying Agent in the Borough of Manhattan, The City of New York, if (but only if)
payment in Dollars of the full amount of such principal, premium, or Make-Whole
Amount, interest or Additional Amounts, as the case may be, at all offices or
agencies outside the United States maintained for the purpose by the Company in
accordance with this Indenture, is illegal or effectively precluded by exchange
controls or other similar restrictions.

                The Company 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 designation or
rescission shall in any manner relieve the Company 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 Company 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 Company hereby designates as a Place of Payment for each series
of Securities the office or agency of the Company in the Borough of Manhattan,
The City of New York, 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 Indenture, then
the Company 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 Company 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 Company shall have one or more Paying Agents for
any series of 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 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 Company
will promptly notify the Trustee of its action or failure so to act.

                The Company 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 (or
premium or Make-Whole Amount, if any) or interest on Securities 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 Company (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; 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 Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company 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 Company 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
Company, in trust for the payment of the principal of (and premium or Make-Whole
Amount, if any) or interest on or Additional Amounts in respect of, any Security
of any series and remaining unclaimed for two years after such principal (or
premium or Make-Whole Amount, if any) or interest or Additional Amounts has
become due and payable shall be paid to the Company upon Company Request or (if
then held by the Company) shall be discharged from such trust; and the Holder of
such Security shall thereafter, as an unsecured general creditor, look only to


                                      -52-
<PAGE>



the Company for payment of such principal of (and premium or Make-Whole Amount,
if any) or interest on or 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 Company 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 Company 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
Company.

                SECTION 1004. Limitations on Incurrence of Indebtedness. Neither
the Company nor any Subsidiary will incur any Indebtedness if, immediately after
giving effect to the incurrence of that additional Indebtedness and the
application of the proceeds thereof, the aggregate principal amount of all
outstanding Indebtedness of the Company and its Subsidiaries on a consolidated
basis determined in accordance with GAAP is greater than 60% of the sum of
(without duplication) (i) the Total Assets of the Company and its Subsidiaries
as of the end of the calendar quarter covered in the Company's Annual Report on
Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently
filed with the Commission (or, if the filing is not permitted under the Exchange
Act, with the Trustee) prior to the incurrence of the additional Indebtedness
and (ii) the purchase price of any real estate assets or mortgages receivable
acquired and the amount of any securities offering proceeds received (to the
extent that the proceeds were not used to acquire real estate assets or
mortgages receivable or used to reduce Indebtedness), by the Company or any
Subsidiary since the end of the calendar quarter, including those proceeds
obtained in connection with the incurrence of the additional Indebtedness.

                In addition to the foregoing limitation on the incurrence of
Indebtedness, neither the Company nor any Subsidiary will incur any Indebtedness
secured by any Encumbrance upon any of the property of the Company or any
Subsidiary if, immediately after giving effect to the incurrence of the
additional Indebtedness and the application of the proceeds thereof, the
aggregate principal amount of all outstanding Indebtedness of the Company and
its Subsidiaries on a consolidated basis which is secured by any Encumbrance on
property of the Company or any Subsidiary is greater than 40% of the sum of
(without duplication) (i) the Total Assets of the Company and its Subsidiaries
as of the end of the calendar quarter covered in the Company's Annual Report on
Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently
filed with the Commission (or, if the filing is not permitted under the Exchange
Act, with the Trustee) prior to the incurrence of the additional Indebtedness
and (ii) the purchase price of any real estate assets or mortgages receivable
acquired and the amount of any securities offering proceeds received (to the
extent that the proceeds were not used to acquire real estate assets or
mortgages receivable or used to reduce Indebtedness), by the Company or any
Subsidiary since the end of the calendar quarter, including those proceeds
obtained in connection with the incurrence of the additional Indebtedness.

                The Company and its Subsidiaries may not at any time own Total
Unencumbered Assets equal to less than 150% of the aggregate outstanding
principal amount of the Unsecured Indebtedness of the Company and its
Subsidiaries on a consolidated basis.

                In addition to the foregoing limitations on the incurrence of
Indebtedness, neither the Company nor any Subsidiary will incur any Indebtedness
if the ratio of Consolidated Income Available for Debt Service to the Annual
Service Charge for the four consecutive fiscal quarters most recently ended
prior to the date on which the additional Indebtedness is to be incurred shall
have been less than 1.5:1 on a pro forma basis after giving effect thereto and
to the application of the proceeds therefrom, and calculated on the assumption
that (i) the Indebtedness and any other Indebtedness incurred by the Company and
its Subsidiaries since the first day of the four-quarter period and the



                                      -53-
<PAGE>



application of the proceeds therefrom, including to finance other Indebtedness,
had occurred at the beginning of the period, (ii) the repayment or retirement of
any other Indebtedness by the Company and its Subsidiaries since the first day
of the four-quarter period had been repaid or retired at the beginning of that
period (except that, in making the computation, the amount of Indebtedness under
any revolving credit facility shall be computed based upon the average daily
balance of the Indebtedness during that period), (iii) in the case of Acquired
Indebtedness or Indebtedness incurred in connection with any acquisition since
the first day of the four-quarter period, the related acquisition had occurred
as of the first day of the period with the appropriate adjustments with respect
to the acquisition being included in the pro forma calculation, and (iv) in the
case of any acquisition or disposition by the Company or its Subsidiaries of any
asset or group of assets since the first day of the four-quarter period, whether
by merger, stock purchase or sale, or asset purchase or sale, the acquisition or
disposition and any related repayment of Indebtedness had occurred as of the
first day of the period with the appropriate adjustments with respect to the
acquisition or disposition being included in the pro forma calculation.

                SECTION 1005. [Omitted].

                SECTION 1006. Existence. Subject to Article Eight, the Company
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 Company 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 Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.

                SECTION 1007. Maintenance of Properties. The Company 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 the Company may be necessary so
that the business carried on in connection therewith may be properly and
advantageously conducted at all times; provided, however, that nothing in this
Section shall prevent the Company or any Subsidiary from selling or otherwise
disposing for value its properties in the ordinary course of its business.

                SECTION 1008. Insurance. The Company will, and will cause each
of its Subsidiaries to, keep all of its insurable properties insured against
loss or damage at least equal to their then full insurable value with
financially sound and reputable insurers.

                SECTION 1009. Payment of Taxes and Other Claims. The Company
will pay or discharge or cause to be paid or discharged, before the same shall
become delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or upon the income, profits or property of the
Company or any Subsidiary, and (2) all lawful claims for labor, materials and
supplies which, if unpaid, might by law become a lien upon the property of the
Company or any Subsidiary; provided, however, that the Company 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 Company is subject to Section 13 or 15(d) of the Exchange Act, the Company
will, to the extent permitted under the Exchange Act, file with the Commission
the annual reports, quarterly reports and other documents which the Company
would have been required to file with the Commission pursuant to such Section 13
or 15(d) (the "Financial Statements") if the Company 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 Company would have been required so
to file such documents if the Company were so subject.

                The Company 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 Company would have been
required to file with the Commission pursuant to Section 13 or 15(d) of the
Exchange Act if the Company were subject to such Sections, and (ii) file with
the Trustee copies of the annual reports, quarterly reports and other documents
which the Company would have been required to file with the Commission pursuant
to Section 13 or 15(d) of the Exchange Act if the Company were subject to such
Sections and (y) if filing such documents by the Company with the Commission is
not permitted 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 Company will
deliver to the Trustee, within 120 days after the end of each fiscal year, a
brief certificate from the principal executive officer, principal financial
officer or principal accounting officer as to his or her knowledge of the
Company's compliance with all conditions and covenants under this Indenture and,
in the event of any noncompliance, specifying such noncompliance and the nature
and status thereof. For purposes of this Section 1011, such compliance shall be
determined without regard to any period of grace or requirement of notice under
this Indenture.

                SECTION 1012. Additional Amounts. If any Securities of a series
provide for the payment of Additional Amounts, the Company will pay to the
Holder of any Security of such series or any coupon appertaining thereto
Additional Amounts as may be specified in this Indenture. Whenever in this
Indenture there is mentioned, in any context except in the case of Section
502(1), 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 this
Indenture 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 Company will furnish
the Trustee and the Company's principal Paying Agent or Paying Agents, if other
than the Trustee, with 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 Company will pay
to the Trustee or such Paying Agent the Additional Amounts required by the terms
of such Securities. If the Trustee 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



                                      -55-
<PAGE>



principal and interest with respect to the Securities of a series or related
coupons without withholding or deductions until otherwise advised. The Company
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 them or in reliance on any Officers' Certificate
furnished pursuant to this Section or in reliance on the Company's not
furnishing such an Officers' Certificate.

                SECTION 1013. Waiver of Certain Covenants. The Company may omit
in any particular instance to comply with any term, provision or condition set
forth in Sections 1004 to 1010, 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 such series, 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 Company 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 Company to redeem any Securities shall be evidenced by or
pursuant to a Board Resolution. In case of any redemption at the election of the
Company of less than all of the Securities of any series, the Company shall, at
least 45 days prior to the giving of the 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 Company 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 Company 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.

                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, but 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:

                (1) the Redemption Date,

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

                (3) 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,

                (4) 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,

                (5) 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,

                (6) 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, or for conversion,

                (7) 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 Company and
the Trustee for such series and any Paying Agent is furnished,

                (8) 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 Redemption Date pursuant to Section 305 or otherwise, the
last date, as determined by the Company, on which such exchanges may be made,

                (9) the CUSIP number of such Security, if any, and

               (10) 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.

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

                SECTION 1105. Deposit of Redemption Price. At least one Business
Day prior to any Redemption Date, the Company shall deposit with the Trustee or
with a Paying Agent (or, if the Company is acting as its own Paying Agent,
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, 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 Company 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 Company at the Redemption Price, together with
accrued interest, 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, 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 Company 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 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 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 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


                                      -58-
<PAGE>




Company or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or his attorney duly authorized in writing) and the
Company shall execute and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge a new 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.


                                 ARTICLE TWELVE


                             [INTENTIONALLY OMITTED]


                                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 Company 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 Company is acting as its own Paying Agent, 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 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 there for specified in the terms of such Security (or at
such other place or places of which the Company 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. ("NASD"), 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



                                      -59-
<PAGE>



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, 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 denomination 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
Company.

                SECTION 1304. When Securities Presented for Repayment Become Due
and Payable. If Securities of any series provide 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
portion thereof, as the case may be, to be repaid shall become due and payable
and shall be paid by the Company on the Repayment Date therein specified, and on
and after such Repayment Date (unless the Company 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 coupons, if any, appertaining
thereto maturing after the Repayment Date, the principal amount of such Security
so to be repaid paid by the Company, together with accrued interest, if any,
Repayment Date; provided, however, that coupons whose Stated Maturity is on or
prior to the Repayment Date shall be payable 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 with interest thereon, unless
the Company 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 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
Company and the Trustee if there be furnished to it such security or indemnity
as they may require to save it 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 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.

                SECTION 1305. Securities Repaid in Part. Upon surrender of any
Registered Security which is to be repaid in part only, the Company shall
execute and the Trustee shall authenticate and deliver to the Holder of such
Security, without service charge and at the expense of the Company, 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; Company'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 Company 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 Company's
exercise of the above option applicable to this Section with respect to any
Securities of or within a series, the Company 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 Company 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
Company, 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 to 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, if
any, on such Securities and any coupons appertaining thereto when such payments
are due, (B) the Company'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, (C) the
rights, powers, trusts, duties and immunities of the Trustee hereunder and (D)
this Article. Subject to compliance with this Article Fourteen, the Company 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 Company's exercise
of the above option applicable to this Section with respect to any Securities of
or within a series, the Company shall be released from its obligations under
Sections 1004 to 1010, inclusive and, if specified pursuant to Section 301, its
obligations under any other covenant, with respect to such Outstanding
Securities and coupons appertaining thereto on and after the date the conditions
set forth in Section 1404 are satisfied (hereinafter, "covenant defeasance"),


                                      -61-

and such Securities and any coupons 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 Sections 1004 to 1010, inclusive, or such other 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 Company 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 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(3) or 501(7) otherwise, as the case may be, but,
except as specified above, 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 Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee satisfying the requirements of
Section 607 who shall agree to comply with the provisions of this Article
Fourteen applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefit of the Holders of such Securities and any coupons appertaining
thereto, (1) an amount in such currency, currencies or currency unit in which
such Securities and any coupons appertaining thereto are then specified as
payable at Stated Maturity, or (2) Government Obligations applicable to such
Securities and coupons appertaining thereto (determined on the basis of the
currency, currencies or currency unit in which such Securities and coupons
appertaining thereto are then specified as payable at Stated Maturity) which
through the scheduled payment of principal and interest in respect thereof in
accordance with the terms will provide, not later than one day before the due
date of any payment of principal of (and premium or Make-Whole Amount, if any)
and interest, if any, on such Securities and any coupons appertaining thereto,
money in an amount, or (3) a combination thereof, any case, in an amount,
sufficient, without consideration of any reinvestment of such principal and
interest, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered the Trustee,
to pay and discharge, and which shall be applied by the Trustee (or other
qualifying trustee) to pay and discharge, the principal of (and premium or
Make-Whole Amount, if any) and interest, if any, on such Outstanding Securities
and any coupons, appertaining thereto on the Stated Maturity of such principal
or installment of principal or interest or analogous payments applicable to such
Outstanding Securities and any coupons appertaining thereto on the day on which
such payments are due and payable in accordance with the terms of this Indenture
and of such Securities and any coupons appertaining thereto.

                (b) Such defeasance or covenant defeasance shall not result in a
breach or violation of, or constitute a default under, this Indenture or any
other material agreement or instrument to which the Company is a party or by
which it is bound.

                (c) No Event of Default or event which with notice or lapse of
time or both would become an Event of Default with respect to such Securities
and any coupons appertaining thereto shall have occurred and be continuing on
the date of such deposit or, insofar as Sections 501(5) and 501(6) are
concerned, at any time during the period ending on the 91st day after the date
of such deposit (it being understood that this condition shall not be deemed
satisfied until the expiration of such period).

                (d) In the case of an election under Section 1402, the Company
shall have delivered to the Trustee an Opinion of Counsel stating that (i) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (ii) since the date of execution of this Indenture, there
has been a change in the applicable Federal income tax law, in either case to
the effect that, and based thereon such opinion shall confirm that, the Holders
of such Outstanding Securities and any coupons appertaining thereto will not
recognize income, gain or loss for Federal income tax purposes as a result of
such defeasance and will be subject to 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 had not occurred.

                (e) In the case of an election under Section 1403, the Company
shall have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Outstanding Securities and any coupons appertaining thereto will
not recognize income, gain or loss for Federal income tax purposes as a result
of such covenant defeasance and will be subject to Federal income tax on the
same amounts, in the same manner and at the same times as would have been the
case if such covenant defeasance had not occurred.

                (f) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent to the defeasance under Section 1402 or the covenant defeasance under
Section 1403 (as the case may be) have been complied with and an Opinion of
Counsel to the effect that either (i) as a result of a deposit pursuant to
subsection (a) above and the related exercise of the Company's option under
Section 1402 or Section 1403 (as the case may be), registration is not required
under the Investment Company Act of 1940, as amended, by the Company with
respect to the trust funds representing such deposit or by the Trustee for such
trust funds or (ii) all necessary registrations under said Act have been
effected.

                (g) Notwithstanding any other provisions of this Section, such
defeasance or covenant defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations which may be imposed
on the Company in connection therewith.

                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
respect of any Outstanding Securities of any series and any coupons appertaining
thereto shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and any coupons appertaining thereto and this
Indenture, to the payment, either directly or through any Paying Agent as the
Trustee may determine, to the Holders of such Securities and any coupons
appertaining thereto of all sums due and to become due thereon in respect of
principal (and 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.

                Unless otherwise specified with respect to any Security pursuant
to Section 301, 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 currency or
currency unit 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


                                      -63-
<PAGE>



Amount, if any), and interest, if any, on 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 currency or currency unit in effect (as
nearly as feasible) at the time of the Conversion Event.

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

from time to time pursuant to this Article to make, give or take any request,

provided by this Indenture to be made, given or taken by Holders of Securities
of such series.

                SECTION 1502. Call, Notice and Place of Meetings. (a) The
Trustee may at any time call a meeting of Holders of Securities of any series
for any purpose specified in Section 1501, to be held at such time and at such
place as the Trustee shall determine. Notice of every meeting of Holders of
Securities of any series, setting forth the time and the place of such meeting
and in general terms the action proposed to be taken at such meeting, shall be

Outstanding Securities of any series shall have requested the Trustee to call a

proposed to be taken at the meeting, and the Trustee shall not have made the
first publication of the notice of such meeting within 21 days after receipt of
such request or shall not thereafter proceed to cause the meeting to be held as
provided herein, then the Company or the Holders of Securities of such series in
the amount above specified, as the case may be, may determine the time and the

majority in principal amount of the Outstanding Securities of a series shall
constitute a quorum for a meeting of Holders of Securities of such series;
provided, however, that if any Act is to be taken at such meeting with respect
to a consent or waiver which this Indenture expressly provides may be given by
the Holders of not less than a specified percentage in principal amount of the
Outstanding Securities of a series, the Persons entitled to vote such specified

the meeting may be adjourned for a period of not less than 10 days as determined
by the chairman of the meeting prior to the adjournment of such meeting. In the
absence of a quorum at any such adjourned meeting, such adjourned meeting may be
further adjourned for a period of not less than 10 days as determined by the

percentage, as provided above, of the principal amount of the Outstanding
Securities of such series which shall constitute a quorum.

                Except as limited by the proviso to Section 902, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted by the affirmative vote of the Holders of a
majority in principal amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 902, any
resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other Act which this Indenture expressly provides may
be made, given or taken by the Holders of a specific percentage, that is less
than a majority in principal amount of the Outstanding Securities of a series
may be adopted at a meeting or an adjourned meeting duly reconvened and at which
a quorum is present as aforesaid by the affirmative vote of the Holders of such
specified percentage in principal amount of the Outstanding Securities of that
series.

                Any resolution passed or decision taken at any meeting of
Holders of Securities of any series duly held in accordance with this Section
shall be binding on all of the Holders of Securities of such series and the
related coupons, whether or not present or represented at the meeting.

determining whether such request, demand, authorization, direction, notice,
consent, waiver or other action has been made, given or taken under this
Indenture.

                SECTION 1505. Determination of Voting Rights; Conduct and
Adjournment of Meetings. (a) Notwithstanding any provisions of this Indenture,
the Trustee may make such reasonable regulations as it may deem advisable for
any meeting of Holders of Securities of a series in regard to proof of the
holding of Securities 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 vote,
and such other matters concerning the conduct of the meeting as it shall deem
appropriate. Except as otherwise permitted or required by any such regulations,
the holding of Securities shall be proved in the manner specified in Section 104
and the appointment of any proxy shall be proved in the manner specified in
Section 104 or by having the signature of the 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 appointing proxies, regular on their face, may
be presumed valid and 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 called by
the Company or by Holders of Securities provided in Section 1502(b), in which
case the Company 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
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

                (c) At any meeting each Holder of a Security of such series or
proxy shall be 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.

                SECTION 1506. Counting Votes and Recording Action of Meetings.
The 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 meeting and one such copy shall be delivered to the
Company 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 Act provided
by this Indenture to be given or taken by a specified percentage in principal


                                      -66-
<PAGE>



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 an agent duly appointed in writing; and,
except as herein otherwise expressly provided, such Act shall become effective
when such instrument or instruments are delivered to the Trustee. Proof of
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 Company, 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 accordance with such reasonable rules and regulations as may be
prescribed by the Trustee or in such manner as shall be satisfactory to the
Trustee.

                            ************

                This Indenture may be executed in any number of counterparts,
each of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same Indenture.

[Insert title or sufficient description of Securities to be delivered]

                This is to certify that, as of the date hereof, and except as
set forth below, the above-captioned Securities held by you for our account (i)
are owned by person(s) that are not citizens or residents of the United States,
domestic Companies, domestic corporations or any estate or trust the income of
which is subject to United States federal income taxation regardless of its
source ("United States person(s)"), (ii) are owned by United States person(s)
that are (a) foreign branches of United States financial institutions (financial
institutions, as defined in United States Treasury Regulations Section
2.165-12(c)(1)(v) are herein referred to as "financial institutions") purchasing
for their own account or for resale, or (b) United States person(s) who acquired
the Securities through foreign branches of United States financial institutions
and who hold the Securities through such United States financial institutions on
the date hereof (and in either case (a) or (b), each such United States
financial institution hereby agrees, on its own behalf or through its agent,
that you may advise Colonial Prospective Trust or its agent that such financial
institution will comply with the requirements of Section 165(j)(3)(A), (B) or
(C) of the United States Internal Revenue Code of 1986, as amended, and the
regulations thereunder), or (iii) are owned by United States or foreign

has not acquired the Securities for purposes of resale directly or indirectly to
a United States person or to a person within the United States or its
possessions.

                As used herein, "United States" means the United States of
America (including the States and the District of Columbia); and "possessions"

[Insert title or sufficient description of Securities to be delivered]


                This is to certify that, based solely on written certifications
that we have received in writing, by tested telex or by electronic transmission
from each of the persons appearing in our records as persons entitled to a
portion of the principal amount set forth below (our "Member Organizations")
substantially in the form attached hereto, as of the date hereof, [U.S. $]
________________________________ principal amount of the above-captioned

United States, domestic Companies, domestic corporations or any estate or trust
the income of which is subject to United States Federal income taxation
regardless of its source ("United States person(s)"), (ii) is owned by United
States person(s) that are (a) foreign branches of United States financial
institutions (financial institutions, as defined in U.S. Treasury Regulations
Section 1.165-12(c)(1)(v) are herein referred to as "financial institutions")
purchasing for their own account or for resale, or (b) United States person(s)
who acquired the Securities through foreign branches of United States financial
institutions and who hold the Securities through such United States financial
institutions on the date hereof (and in either case (a) or (b), each such
financial institution has agreed, on its own behalf or through its agent, that
we may advise Colonial Prospective Trust or its agent that such financial
institution will comply with the requirements of Section 165(j) (3) (A), (B) or
(C) of the Internal Revenue Code of 1986, as amended, and the regulations
thereunder), or (iii) is owned by United States or foreign financial
institution(s) for purposes of resale during the restricted period (as defined
in United States Treasury Regulations Section 1.163-5(c)(2)(i)(D)(7)), and, to
the further effect, that financial institutions described in clause (iii) above
(whether or not also described in clause (i) or (ii)) have certified that they
have not acquired the Securities for purposes of resale directly or indirectly
to a United States person or to a person within the United States or its
possessions.

                As used herein, "United States" means the United States of
America (including the States and the District of Columbia); and its
"possessions" include Puerto Rico, the U.S. Virgin Islands, Guam, American
Samoa, Wake Island and the Northern Mariana Islands.

                We further certify that (i) we are not making available herewith
for exchange (or, if relevant, collection of any interest) any portion of the
temporary global Security representing the above captioned Securities excepted
in the above-referenced certificates of Member Organizations and (ii) as of the
date hereof we have not received any notification from any of our Member
Organizations to the effect that the statements made by such Member
Organizations with respect to any portion of the part submitted herewith for
exchange (or, if relevant, collection of any interest) are no longer true and
cannot be relied upon as of the date hereof.

                We understand that this certification is required in connection
with certain tax legislation in the United States. If administrative or legal

month) corresponding to the remaining life to maturity, as of the payment date,

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 purposes of calculating the

                  SECTION 103. Form of Documents Delivered to Trustee. In any

be so certified or covered by only one document, but one such Person may certify
or give an opinion as to some matters and one or more other such Persons as to

matters in one or several documents.

                  Any certificate or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon an Opinion of Counsel, or a
certificate or representations 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

                  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 of the Outstanding Securities of
all series or one or more series, as the case may be, 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 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 Company. 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 conclusive
in favor of the Trustee and the Company and any agent of the Trustee or the
Company, 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 by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other reasonable manner which the Trustee deems sufficient.

                  (c) The ownership of Registered Securities shall be proved by
the Security Register.


                                      -13-
<PAGE>

                  (d) The ownership of Bearer Securities 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, wherever
situated, if such certificate shall be deemed by 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 Company 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 of Bearer
Securities may also be proved in any other manner which the Trustee deems
sufficient.

                  (e) If the Company shall solicit from the Holders of
Registered Securities any request, demand, authorization, direction, notice,
consent, waiver or other Act, the Company may, at its option, in or pursuant to
a Board Resolution, fix in advance a record date for the determination of
Holders entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so.
Notwithstanding TIA Section 316(c), such record date shall be the record date
specified in or pursuant to such Board Resolution, which shall be a date not
earlier than the date 30 days prior to the first solicitation of Holders
generally in connection therewith and not later than the date such solicitation
is completed. 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 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 Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

                  SECTION 105. Notices, etc., to Trustee and Company. 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,

                  (1) the Trustee by any Holder or by the Company 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

                  (2) the Company 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 Company
addressed to it at the address of its principal office specified in the first
paragraph of this Indenture or at any other address previously furnished in
writing to the Trustee by the Company.

                  SECTION 106. Notice to Holders; Waiver. Where this Indenture
provides for notice of any event to Holders of Registered Securities by the
Company 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
The City of New York 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
or waiver required or permitted under this Indenture shall be in the English
language, except that 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 notice. Waivers of notice by Holders shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

                  SECTION 107. Effect of Headings and Table of Contents. The
Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

                  SECTION 108. Successors and Assigns. All covenants and
agreements in this Indenture by the Company shall be binding on their successors
and assigns, whether so expressed or not.

                  SECTION 109. Separability Clause. In case any provision in
this Indenture or in any Security or coupon shall be 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,
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. No Personal Liability. 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 indebtedness
evidenced thereby, shall be had against any promoter, as such, or against any
past, present or future shareholder, officer or director, as such, of the
Company or of any successor, either directly or through the Company 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.

                  SECTION 112. Governing Law. This Indenture and the Securities
and coupons shall be governed by and construed in accordance with the law of the
State of ____________.

                  SECTION 113. 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 shall not be a Business Day at any Place of
Payment, then (notwithstanding any other provision of this Indenture or any
Security or coupon other than a provision in the Securities of any series which
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, but may
be made 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, 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, as the case may
be.

Security in global form to reflect the amount, or any increase or decrease in
the amount, of Outstanding Securities represented thereby shall be made by the
Trustee in such manner and upon instructions given by such Person or Persons as
shall be specified therein or in the Company Order to be delivered to the
Trustee 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 Company Order. If a
Company Order pursuant to Section 303 or 304 has been, or simultaneously is,
delivered, any instructions by the Company 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 Company and the Company 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 any Security in 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 Company, the Trustee and any agent of
the Company and the Trustee shall treat as the Holder of such principal amount
of Outstanding Securities represented by a permanent global Security (i) in the
case of a permanent global Security in registered form, the Holder of such
permanent global Security in registered form, or (ii) in the case of a permanent
global Security in bearer form, Euroclear or CEDEL.

or the Person to whom, any interest on any Bearer Security of the series shall
be payable, if otherwise than upon presentation and surrender of the coupons

manner in which, any interest payable on a temporary global Security on an
Interest Payment Date will be paid if other than in the manner provided in
Section 304;

                  (19) the applicability, if any, of Sections 1402 and/or 1403
to the Securities of the series and any provisions in modification of, in
addition to or in lieu of any of the provisions of Article Fourteen;

                  (20) if the Securities of such series are to be issuable in

such certificates, documents or conditions;

                  (23) any other terms of the series (which terms shall not be

                  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

                  SECTION 302. Denominations. The Securities of each series
shall be issuable in such denominations as shall be specified as contemplated by
Section 301. With respect to Securities of any series denominated in Dollars, in
the absence of any such provisions with respect to the Securities of any series,
the Registered Securities of such series, 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 of such series, other than Bearer Securities issued in global form
(which may be of any denomination), shall be issuable in a denomination of
$5,000.

                  SECTION 303. Execution, Authentication, Delivery and Dating.
The Securities and any coupons appertaining thereto shall be executed by the
Company's Chairman of the Board, Chief Financial Officer, President, Secretary
or one of its Executive Vice Presidents. 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 Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and
delivery of such Securities 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 Company may deliver Securities of any series,
together with any coupon appertaining thereto, executed by the Company to the
Trustee for authentication, together with a Company Order for the authentication
and delivery of such Securities, and the Trustee in accordance with the Company
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, 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
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 Company 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,

                  (i) an Opinion of Counsel complying with Section 102 and
stating that

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


                                      -21-
<PAGE>

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

                      (c) such Securities, together with any coupons
appertaining thereto, when completed by appropriate insertions and executed and
delivered by the Company 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 Company in the manner and subject to any
conditions specified in such Opinion of Counsel, will constitute legal, valid
and binding obligations of the Company, 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

                  (ii) 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, that 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 a Company 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.

                  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 Company, and the Company 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
Company, 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 Company may execute, and upon
Company 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. In the case of Securities of
any series, such temporary Securities may be in global form.


                                      -22-
<PAGE>

                  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 Company 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 Company 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 non-matured coupons appertaining thereto), the Company 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 Section 303.
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. 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 Company shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary global Security, executed by the Company. On or after
the Exchange Date, such temporary global Security shall be surrendered by the
Common Depositary to the Trustee, as the Company'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 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.


                                      -23-
<PAGE>

                  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 the Trustee prior to the expiration of two years after such Interest
Payment Date in order to be repaid to the Company.

                  SECTION 305. Registration, Registration of Transfer and
Exchange. The Company shall cause to be kept at the Corporate Trust Office of
the Trustee or in any office or agency of the Company 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 Company 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 Company 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 initially appointed

                  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 Company in a Place of Payment for that series, the
Company 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.

                  Subject to the provisions of this Section 305, at the option
of the Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series, of any authorized denomination or
denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be
exchanged at any such office or agency. Whenever any such Registered Securities
are so surrendered for exchange, the Company 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 Company 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 Company 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 Company 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
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 selected or approved by the Company or to a
nominee of such successor to DTC. If at any time DTC notifies the Company 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 Company 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 Company within 90 days
after the Company 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 Company, 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 Company 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. 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 date on which
such interest may be so exchanged, the Company 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 Company
Order with respect thereto to the Trustee, as the Company'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 Company, 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 Company or the Security Registrar) be duly endorsed, or be accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar, duly executed by the Holder thereof or his attorney duly
authorized in writing.

                  No service charge shall be made for any registration of
transfer or exchange of Securities, but the Company 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 Section 304, 906, 1107 or 1305 not involving any
transfer.

                  The Company, the Trustee or the Security Registrar, 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 Company, together with, in appropriate
cases, such security or indemnity as may be required by the Company or the
Trustee to hold each of them or any agent of either of them harmless, the
Company 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 Company 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 hold each of them and any agent of either of them harmless, then, in the
absence of notice to the Company or the Trustee that such Security or coupon has
been acquired by a bona fide purchaser, the Company shall execute and upon the
Company's 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 immediately preceding
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 Company 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), any 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 on Bearer Securities shall be payable only upon presentation and
surrender of the coupons appertaining thereto.

<PAGE>

                  Upon the issuance of any new Security under this Section, the
Company 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 Company, 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 hereunder.

                  The provisions of this Section 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 Preserved.
Except as otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 301, interest on 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
Company maintained for such purpose pursuant to Section 1002; provided, however,
that each installment of interest on any Registered Security may at the
Company'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 Company at its election in each case,
as provided in clause (1) or (2) below:

                  (1) The Company 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 Company 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 Company 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 in this clause provided. 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 Company of such Special Record Date and, in the name and at the
expense of the Company, 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 Company, 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 therefor 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 (2). 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.

                  (2) The Company 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 Company 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 Company, the Trustee
and any agent of the Company 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, such Registered
Security and for all other purposes whatsoever, whether or not such Registered
Security be overdue, and none of the Company, the Trustee or any agent of the
Company 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 Company, the Trustee and any agent of the
Company 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 payment thereof or on account thereof and for all other
purposes whatsoever, whether or not such Security or coupon be overdue, and none
of the Company, the Trustee or any agent of the Company or the Trustee shall be
affected by notice to the contrary.

                  None of the Company, 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 Company, the Trustee, or any agent of
the Company, 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. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company 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 Company
has not issued and sold, and all Securities so delivered shall be promptly
canceled by the Trustee. If the Company 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 destroyed by the Trustee and
the Trustee shall deliver a certificate of such destruction to the Company,
unless, by the Company Order, the Company 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 of each series shall be computed on the basis
of a 360-day year consisting of twelve 30-day months.

rule or regulation of any administrative or governmental body):

                  (1) default in the payment of any interest upon or any

days; or

                  (2) default in the payment of the principal of (or premium or

failure of any Subsidiary to comply with the provisions in Section 1004, and, in
each case, continuance of such default or breach for a period of 60 days after

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

in an aggregate principal amount in excess of $5,000,000, whether the

                  (5) the Company or any Significant Subsidiary pursuant to or
within the meaning of any Bankruptcy Law:

                      (A) commences a voluntary case,

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

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

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

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

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

                      (B) appoints a Custodian of the Company or any Significant
                          Subsidiary for all or substantially all of either of

                      (C) orders the liquidation of the Company or any
                          Significant Subsidiary,

and the order or decree remains unstayed and in effect for 90 days; or

                  (7) any other Event of Default provided 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 in every such case the
Trustee or the Holders of not 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, and
premium or Make-Whole Amount, if any, on all the Securities of that series to be
due and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by the Holders), and upon any such declaration such principal,
and premium and Make-Whole Amount (if any), or specified portion thereof shall
become immediately due and payable. If an Event of Default with respect to the
Securities of any series set forth in Section 501(5) or (6) of this Indenture
occurs and is continuing, then in every such case all the Securities of that
series shall become immediately due and payable, without notice to the Company,
at the principal amount thereof plus accrued interest to the date the Securities
of that series are paid plus any Make-Whole Amount due on the Securities of that
series.

                  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 a majority in principal
amount of the Outstanding Securities of that series, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequences if:


                                      -33-
<PAGE>

                  (1) the Company has paid or deposited with the Trustee a sum
sufficient to pay in the currency, 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):

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

                      (B) 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 at
                          the rate or rates borne by or provided for in such
                          Securities,

                      (C) to the extent that payment of such interest 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

                      (D) 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

                  (2) 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 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 Company covenants that if:

                  (1) 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

                  (2) 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 upon redemption, upon dedication or otherwise, then the Company 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 Amount, 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 Company 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 Company, or any other obligor upon such Securities
of such series and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or any other obligor
upon such Securities of such series, wherever situated.

<PAGE>

                  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 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 Company or any other obligor upon the Securities or
the property of the Company 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 Company for the payment of overdue principal, premium or Make-Whole Amount,
if any, or interest) shall be entitled and empowered, by intervention in such
proceeding or otherwise:

                  (i) 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 to file such other
                  papers or documents as may be necessary or advisable in order
                  to have the 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

                  (ii) to collect and receive any moneys or 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 Securities of such series or 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.

                  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 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: To the payment of the remainder, if any, to the
Company.

                  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:

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

                  (2) 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;

                  (3) 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;

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

                  (5) 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 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
due dates expressed in such Security or coupon (or, in the case of redemption,
on the Redemption 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.

<PAGE>

                  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 Company, 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
the Holders 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 the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders 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, provided that

                  (1) such direction shall not be in conflict with any rule of
law or with this Indenture,

                  (2) the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction, and

                  (3) 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


                                      -37-
<PAGE>

                  (1) 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

                  (2) 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, any
Event of Default arising therefrom shall be deemed to have been cured, and for
every purpose of this Indenture, the Company, Trustee and Holders shall be
restored to their former positions and rights hereunder; 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
Company 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 Company (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 10% 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 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). The Company agrees to pay or reimburse the Trustee for paying
all reasonable costs and expenses (including reasonable counsels' fees) of the
Trustee in connection with (a) any default and any enforcement or collection
proceedings resulting therefrom and (b) the enforcement of this Section 515.

                                   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, 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; 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 a committee of trust
officers of the Trustee in good faith determine that the withholding of such
notice is in the 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(3) 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):

                  (1) except during the continuance of an Event of Default, the
Trustee shall 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;

                  (2) in case a default or an Event of Default has occurred and
is continuing of which a Responsible Officer of the Trustee has actual knowledge
or of which written notice of such default or Event of Default shall have been
given to the Trustee by the Company, any other obligor of the Securities or by
any Holder, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent Person would exercise or use under the circumstances in
the conduct of his own affairs;

                  (3) 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;

                  (4) any request or direction of the Company mentioned herein
shall be sufficiently evidenced by a Company Request or Company 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;

                  (5) 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;

                  (6) 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;

                  (7) 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 Company personally or by agent or attorney;

                  (8) in the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the

hereunder or perform any duties hereunder either directly or by or through
agents or attorneys and the Trustee shall not be responsible for any misconduct
or negligence on the part of any agent or attorney appointed with due care by it
hereunder; and

                  (10) no provision of this Indenture shall be construed to
relieve the Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that

                       (a) this paragraph (10) shall not be construed to limit
                  the effect of paragraph (1) of this Section;

                       (b) the Trustee shall not be liable for any errors of
                  judgment or any acts, omissions, mistakes of fact or law taken
                  or omitted in good faith by a Responsible Officer, unless it
                  shall be proved that the Trustee was negligent;

                       (c) the Trustee shall not be liable with respect to any
                  action taken or omitted to be taken by it in good faith in
                  accordance with the direction of the Holders of a majority in
                  aggregate principal amount of the Outstanding Securities of
                  such series relating to the time, method and place of
                  conducting any proceeding for any remedy available to the
                  Trustee, or exercising any trust or power conferred upon the
                  Trustee, under this Indenture; and

                       (d) no provision of this Indenture shall require the
                  Trustee 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.

                  (11) Whether nor not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section.

                  The permissive right of the Trustee to do the things
enumerated in this Indenture shall not be construed as a duty, and the Trustee
shall not be answerable for other than its negligence or willful misconduct.

                  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 Company and neither the Trustee nor any Authenticating
Agent assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity, legality 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. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company 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
Company, 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,
may otherwise deal with the Company with the same rights it would have if it
were not the Trustee, Paying Agent, Security Registrar, Authenticating Agent or
such other agent.

                  SECTION 605. Money Held in Trust. 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 Company.

                  SECTION 606. Compensation and Reimbursement. The Company
agrees:

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

                  (2) 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

                  (3) 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(5) or Section
501(6), 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
Company under this Section, the Trustee shall have a lien prior to the Holders
of 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 on particular Securities or any coupons.

                  Notwithstanding any provision in this Indenture, the Trustee's
right to immunities and protection from liability hereunder and its rights to
payment of its fees, expenses and indemnities shall survive its resignation or
removal and the final payment or defeasance of the Securities and the
termination of the Indenture and all indemnification and releases from liability
granted herein shall extend to its directors, officers, employees and agents.

                  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 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
Company. If an 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.

                  (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 the
Company.

                  (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 Company or by any
Holder of a Security who has been a bona fide Holder of a Security for at least
six months, or

                      (2) the Trustee shall cease to be eligible under Section
607 and shall fail to resign after written request therefor by the Company 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 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, (i) the Company by or
pursuant to a Board Resolution may remove the Trustee and appoint a successor
Trustee with respect to all Securities, or (ii) 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 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 Company, 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).
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
Company and the retiring Trustee, the successor Trustee so appointed shall,
forthwith upon its acceptance or such appointment, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders of Securities and accepted appointment in the manner hereinafter
provided, 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 Company 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 Company and 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 Company 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.

                  (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
Company, 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 Trustees 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 Company, 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 Company
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 of 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 issued upon exchange, registration of transfer or
partial redemption or repayment thereof, except upon original issuance or in
replacement of mutilated, lost, stolen or destroyed Securities, 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 of which instrument shall
be promptly furnished to the Company. Except upon original issuance or in
replacement of mutilated, lost, stolen or destroyed Securities, wherever
reference is made in this Indenture to the authentication and delivery of
Securities by the Trustee or the Trustee's certificate 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 Company 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 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.

<PAGE>

                  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 Company. 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 the Company. 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 Company 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 Company 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.

any Authenticating Agent nor any Paying Agent nor any Security Registrar shall
be held accountable by reason of the disclosure of any information as to the
names and addresses of the Holders of Securities in accordance with TIA Section
312, regardless of the source from which such information was derived, and that
the Trustee shall not be held accountable by reason of mailing any material
pursuant to a request made under TIA Section 312(b).

                  SECTION 702. Reports by Trustee. Within 60 days after June 30
of each year commencing with the first June 30 after the first issuance of
Securities pursuant to this Indenture, the Trustee shall transmit by mail to all
Holders of Securities as provided in TIA Section 313(c) a brief report dated as

                  SECTION 703. Reports by Company. The Company will:

                  (1) file with the Trustee, within 15 days after the Company is
required to file the same with the Commission, copies of the annual reports and

any of the foregoing as the Commission may from time to time by rules and
regulations prescribe) which the Company may be required to file with the
Commission pursuant to Section 13 or Section 15(d) of the Exchange Act; or the
Company is not required to file information, documents or reports pursuant to
either of such Sections, then it will file with the Trustee and the Commission,

from time to time by such rules and regulations; and

                  (3) transmit by mail to the Holders of Securities, within 30
days after the filing thereof with the Trustee, in the manner and to the extent
provided in TIA Section 313(c), such summaries of any information, documents and
reports required to be filed by the Company pursuant to paragraphs (1) and (2)
of this Section as may be required by rules and regulations prescribed from time
to time by the Commission.

Trustee:

semi-annually, upon such dates as are set forth in the Board Resolution or
indenture supplemental hereto authorizing such series, and

                  (b) at such other times as the Trustee may request in Writing,

consolidate with, or sell, lease or convey all or substantially all of its
assets to, or merge with or into any other entity, provided that in any such
case, (1) either the Company shall be the continuing entity, or the successor
entity shall be an entity organized and existing under the laws of the United
States or a State thereof and such successor entity shall expressly assume the
due and punctual payment of the principal of (and premium or Make-Whole Amount,
if any) and any interest (including all Additional Amounts, if any, payable
pursuant to Section 1012) on all of the Securities, according to



                                      -46-

their tenor, and the due and punctual performance and observance of all of the
covenants and conditions of this Indenture to be performed by the Company by
supplemental indenture, complying with Article Nine hereof, satisfactory to the
Trustee, executed and delivered to the Trustee by such entity and (ii)
immediately after giving effect to such transaction and treating any
indebtedness which becomes an obligation of the Company or any Subsidiary as a
result thereof as having been incurred by the Company or such Subsidiary at the
time or such transaction, no Event of Default, and no event which, after notice
or the lapse of time, or both, would become an Event of Default, shall have
occurred and be continuing.

                  SECTION 802. Rights and Duties of Successor Entity. In case of
any consolidation, merger, sale, lease or conveyance permitted under Section
801 and upon any assumption by the successor entity, such successor entity
shall succeed to and be substituted for the Company, with the same effect as if
it had been named herein as the Company, and the predecessor entity, except in
the event of a lease, shall be relieved of any further obligation under this
Indenture and the Securities. Such successor entity thereupon may cause to be
signed, and may issue either in its own name or in the name of the Company, any
or all of the Securities issuable hereunder which theretofore shall not have
been signed by the Company and delivered to the Trustee; and, upon the order of
such successor entity, instead of the Company, 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 Company to the Trustee for
authentication, and any Securities which such successor entity 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 from the Company with
respect to Section 801 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 entity, complies with the provisions of this Article
and that all conditions precedent herein provided for relating to such
transaction have been complied with.

                             SUPPLEMENTAL INDENTURES

                  SECTION 901. Supplemental Indentures without Consent of
Holders. Without the consent of any Holders of Securities or coupons, the
Company, when authorized by or pursuant to a Board Resolution, and the Trustee,
at any time and from time to time, may enter into one or more indentures
supplemental hereto, in form satisfactory to the Trustee, for any of the
following purposes:

                  (1) to evidence the succession of another Person to the
Company and the assumption by any such successor of the covenants of the Company
herein and in the Securities contained; or

                  (2) to add to the covenants of the Company for the benefit of
the Holders of all or any series of Securities (and if such covenants are to be
for the benefit of less than all series of Securities, stating that such
covenants are expressly being included solely for the benefit of such series) or
to surrender any right or power herein conferred upon the Company; or


                                      -47-
<PAGE>

                  (3) 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

                  (4) 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 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

                  (5) to change or eliminate any of the provisions or 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

                  (6) to secure the Securities; or

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

                  (8) 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

                  (9) 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; or

                  (10) 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.

                  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 Outstanding Securities affected by such supplemental indenture, by Act of
said Holders delivered to the Company and the Trustee, the Company, 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:


                                      -48-
<PAGE>

                  (1) 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 payable in respect thereof, any Security; or reduce
the principal amount thereof or the rate or amount of interest thereon, or any
premium payable upon the redemption thereof, or change any obligation of the
Company to pay Additional Amounts pursuant to Section 1012 (except as
contemplated by Section 801(1) and permitted by Section 901(1)), or reduce the
amount of the principal of an Original Issue Discount Security or Make-Whole
Amount 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, any Security or any premium or Make-Whole
Amount or the interest thereon 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

                  (2) 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

                  (3) 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. In
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 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 and delivery 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 TIA. Every supplemental indenture
executed pursuant to this Article 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 Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company 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 Company and the Trustee of any supplemental indenture
pursuant to the provisions of Section 902, the Company 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 (if any),
Make-Whole Amount (if any), Interest and Additional Amounts. The Company
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
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 Company, 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 Company 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 or conversion, where Securities of that series may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Company 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
Company will maintain: (A) in the Borough of Manhattan, The City of New York, an
office or agency where any Registered Securities of that series may be presented
or surrendered for payment or conversion, where any Registered 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 Company in respect of the Securities of that series and this Indenture
may be served and where Bearer Securities of that series and related



                                      -50-
<PAGE>

coupons may be presented or surrendered for payment or conversion 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) or conversion; 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 Company 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 Company in respect of the Securities of that series and this Indenture
may be served. The Company 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 Company 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) or conversion at the offices specified in
the Security, in London, England, and the Company hereby appoint the same as its
agent to receive such respective presentations, surrenders, notices and demands,
and the Company hereby appoint 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 Company 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 the 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 Company's
Paying Agent in the Borough of Manhattan, The City of New York, if (but only if)
payment in Dollars of the full amount of such principal, premium, or Make-Whole
Amount, interest or Additional Amounts, as the case may be, at all offices or
agencies outside the United States maintained for the purpose by the Company in
accordance with this Indenture, is illegal or effectively precluded by exchange
controls or other similar restrictions.

                  The Company 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 designation or
rescission shall in any manner relieve the Company 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 Company 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 Company hereby designates as a Place of Payment for each series
of Securities the office or agency of the Company in the Borough of Manhattan,
The City of New York, 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 Indenture, then
the Company 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 Company 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 Company shall have one or more Paying Agents for
any series of 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 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 Company
will promptly notify the Trustee of its action or failure so to act.

                  The Company 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
(or premium or Make-Whole Amount, if any) or interest on Securities 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 Company (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; 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 Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company 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 Company 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
Company, in trust for the payment of the principal of (and premium or Make-Whole
Amount, if any) or interest on or Additional Amounts in respect of, any Security
of any series and remaining unclaimed for two years after such principal (or
premium or Make-Whole Amount, if any) or interest or Additional Amounts has
become due and payable shall be paid to the Company upon Company Request or (if
then held by the Company)



                                      -52-
<PAGE>

shall be discharged from such trust; and the Holder of such Security shall
thereafter, as an unsecured general creditor, look only to the Company for
payment of such principal of (and premium or Make-Whole Amount, if any) or
interest, or 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 Company 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
Company 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 Company.

                  SECTION 1004. Limitations on Incurrence of Indebtedness.
Neither the Company nor any Subsidiary will incur any Indebtedness if,
immediately after giving effect to the incurrence of that additional
Indebtedness and the application of the proceeds thereof, the aggregate
principal amount of all outstanding Indebtedness of the Company and its
Subsidiaries on a consolidated basis determined in accordance with GAAP is
greater than 60% of the sum of (without duplication) (i) the Total Assets of the
Company and its Subsidiaries as of the end of the calendar quarter covered in
the Company's Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as
the case may be, most recently filed with the Commission (or, if the filing is
not permitted under the Exchange Act, with the Trustee) prior to the incurrence
of the additional Indebtedness and (ii) the purchase price of any real estate
assets or mortgages receivable acquired and the amount of any securities
offering proceeds received (to the extent that the proceeds were not used to
acquire real estate assets or mortgages receivable or used to reduce
Indebtedness), by the Company or any Subsidiary since the end of the calendar
quarter, including those proceeds obtained in connection with the incurrence of
the additional Indebtedness.

                  In addition to the foregoing limitation on the incurrence of
Indebtedness, neither the Company nor any Subsidiary will incur any Indebtedness
secured by any Encumbrance upon any of the property of the Company or any
Subsidiary if, immediately after giving effect to the incurrence of the
additional Indebtedness and the application of the proceeds thereof, the
aggregate principal amount of all outstanding Indebtedness of the Company and
its Subsidiaries on a consolidated basis which is secured by any Encumbrance on
property of the Company or any Subsidiary is greater than 40% of the sum of
(without duplication) (i) the Total Assets of the Company and its Subsidiaries
as of the end of the calendar quarter covered in the Company's Annual Report on
Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently
filed with the Commission (or, if the filing is not permitted under the Exchange
Act, with the Trustee) prior to the incurrence of the additional Indebtedness
and (ii) the purchase price of any real estate assets or mortgages receivable
acquired and the amount of any securities offering proceeds received (to the
extent that the proceeds were not used to acquire real estate assets or
mortgages receivable or used to reduce Indebtedness), by the Company or any
Subsidiary since the end of the calendar quarter, including those proceeds
obtained in connection with the incurrence of the additional Indebtedness.

                  The Company and its Subsidiaries may not at any time own Total
Unencumbered Assets equal to less than 150% of the aggregate outstanding
principal amount of the Unsecured Indebtedness of the Company and its
Subsidiaries on a consolidated basis.

                  In addition to the foregoing limitations on the incurrence of
Indebtedness, neither the Company nor any Subsidiary will incur any Indebtedness
if the ratio of Consolidated Income Available for Debt Service to the Annual
Service Charge for the four consecutive fiscal quarters most recently ended
prior to the date on which the additional Indebtedness is to be incurred shall
have been less than 1.5:1 on a pro forma basis after giving effect thereto and
to the application of the proceeds therefrom, and calculated on the assumption
that (i) the Indebtedness and any other Indebtedness incurred by the Company and
its Subsidiaries since the first day of the four-quarter period and the
application of the proceeds therefrom, including to finance other Indebtedness,
had occurred at the beginning of the period, (ii) the repayment or retirement of


                                      -53-
<PAGE>

any other Indebtedness by the Company and its Subsidiaries since the first day
of the four-quarter period had been repaid or retired at the beginning of that
period (except that, in making the computation, the amount of Indebtedness under
any revolving credit facility shall be computed based upon the average daily
balance of the Indebtedness during that period), (iii) in the case of Acquired
Indebtedness or Indebtedness incurred in connection with any acquisition since
the first day of the four-quarter period, the related acquisition had occurred
as of the first day of the period with the appropriate adjustments with respect
to the acquisition being included in the pro forma calculation, and (iv) in the

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

business.

                  SECTION 1008. Insurance. The Company will, and will cause each

become delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or upon the income, profits or property of the
Company or any Subsidiary, and (2) all lawful claims for labor, materials and

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.

not the Company is subject to Section 13 or 15(d) of the Exchange Act, the

                  The Company 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 Company would have been
required to file with the Commission pursuant to Section 13 or 15(d) of the
Exchange Act if the Company were subject to such Sections, and (ii) file with
the Trustee copies of the annual reports, quarterly reports and other documents
which the Company would have been required to file with the Commission pursuant
to Section 13 or 15(d) of the Exchange Act if the Company were subject to such
Sections and (y) if filing such documents by the Company with the Commission is
not permitted 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 Company will

brief certificate from the principal executive officer, principal financial

Company's compliance with all conditions and covenants under this Indenture and,
in the event of any noncompliance, specifying such noncompliance and the nature
and status thereof. For purposes of this Section 1011, such compliance shall be
determined without regard to any period of grace or requirement of notice under
this Indenture.

                  SECTION 1012. Additional Amounts. If any Securities of a
series provide for the payment of Additional Amounts, the Company will pay to
the Holder of any Security of such series or any coupon appertaining thereto
Additional Amounts as may be specified in this Indenture. Whenever in this
Indenture there is mentioned, in any context except in the case of Section
502(1), 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 this
Indenture 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 Company will furnish
the Trustee and the Company's principal Paying Agent or Paying Agents, if other
than the Trustee, with 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 Company will pay
to the Trustee or such Paying Agent the Additional Amounts required by the terms
of such Securities. If the Trustee 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 Company
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 them or in reliance on any Officers' Certificate
furnished pursuant to this Section or in reliance on the Company's not
furnishing such an Officers' Certificate.

                  SECTION 1013. Waiver of Certain Covenants. SECTION 1013.
Waiver of Certain CovenantsThe Company may omit in any particular instance to
comply with any term, provision or condition set forth in Sections 1004 to 1010,
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 such
series, 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 Company 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 Company to redeem any Securities shall be evidenced by or
pursuant to a Board Resolution. In case of any redemption at the election of the
Company of less than all of the Securities of any series, the Company shall, at
least 45 days prior to the giving of the 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 Company 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 Company 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.

                  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.

<PAGE>

                  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, but 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:

                  (1) the Redemption Date,

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

                  (3) 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,

                  (4) 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,

                  (5) 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,

                  (6) 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, or for conversion,

                  (7) 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 Company and
the Trustee for such series and any Paying Agent is furnished,

                  (8) 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 Redemption Date pursuant to Section 305 or otherwise, the
last date, as determined by the Company, on which such exchanges may be made,

                  (9) the CUSIP number of such Security, if any, and

                  (10) 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.

<PAGE>

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

                  SECTION 1105. Deposit of Redemption Price. At least one
Business Day prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, 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, 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 Company 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 Company at the Redemption Price, together with
accrued interest, 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, 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 Company 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 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 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 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



                                      -58-
<PAGE>

of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing) and the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security without service charge a
new 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.

                                 ARTICLE TWELVE

                             [INTENTIONALLY OMITTED]

                                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 Company 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 Company is acting as its own Paying Agent, 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 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 there for specified in the terms of such Security (or at
such other place or places of which the Company 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. ("NASD"), 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


                                      -59-
<PAGE>

such telegram, telex, 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 denomination 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
Company.

                  SECTION 1304. When Securities Presented for Repayment Become
Due and Payable. If Securities of any series provide 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 portion thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Company on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Company 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 coupons, if any, appertaining thereto maturing after the Repayment Date,
the principal amount of such Security so to be repaid paid by the Company,
together with accrued interest, if any, Repayment Date; provided, however, that
coupons whose Stated Maturity is on or prior to the Repayment Date shall be
payable 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 with interest thereon, unless the Company 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 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
Company and the Trustee if there be furnished to it such security or indemnity
as they may require to save it 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 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.

authenticate and deliver to the Holder of such Security, without service charge

                  SECTION 1401. Applicability of Article; Company's Option to
Effect Defeasance or Covenant Defeasance. SECTION 1401. Applicability of
Article; Company'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

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

applicable to such Securities and any coupons appertaining thereto, and the
Company 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

                  SECTION 1402. Defeasance and Discharge. Upon the Company's
exercise of the above option applicable to this Section with respect to any
Securities of or within a series, the Company 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 Company 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
Company, 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 to 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, if
any, on such Securities and any coupons appertaining thereto when such payments
are due, (B) the Company'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, (C) the
rights, powers, trusts, duties and immunities of the Trustee hereunder and (D)
this Article. Subject to compliance with this Article Fourteen, the Company 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 Company's exercise
of the above option applicable to this Section with respect to any Securities of
or within a series, the Company shall be released from its obligations under
Sections 1004 to 1010, inclusive and, if specified pursuant to Section 301, its
obligations under any other covenant, with respect to such Outstanding
Securities and 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 appertaining thereto shall thereafter be
deemed to be not "Outstanding" for the purposes of any direction, waiver,


                                      -61-
<PAGE>

consent or declaration or Act of Holders (and the consequences of any thereof)
in connection with Sections 1004 to 1010, inclusive, or such other 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 Company 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 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(3) or 501(7) otherwise, as the case may be, but,
except as specified above, 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:

be deposited with the Trustee (or another trustee satisfying the requirements of
Section 607 who shall agree to comply with the provisions of this Article
Fourteen applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefit of the Holders of such Securities and any coupons appertaining
thereto, (1) an amount in such currency, currencies or currency unit in which
such Securities and any coupons appertaining thereto are then specified as
payable at Stated Maturity, or (2) Government Obligations applicable to such
Securities and coupons appertaining thereto (determined on the basis of the
currency, currencies or currency unit in which such Securities and coupons
appertaining thereto are then specified as payable at Stated Maturity) which
through the scheduled payment of principal and interest in respect thereof in
accordance with the terms will provide, not later than one day before the due
date of any payment of principal of (and premium or Make-Whole Amount, if any)
and interest, if any, on such Securities and any coupons appertaining thereto,
money in an amount, or (3) a combination thereof, any case, in an amount,
sufficient, without consideration of any reinvestment of such principal and
interest, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered the Trustee,
to pay and discharge, and which shall be applied by the Trustee (or other
qualifying trustee) to pay and discharge, the principal of (and premium or
Make-Whole Amount, if any) and interest, if any, on such Outstanding Securities
and any coupons, appertaining thereto on the Stated Maturity of such principal
or installment of principal or interest or analogous payments applicable to such
Outstanding Securities and any coupons appertaining thereto on the day on which
such payments are due and payable in accordance with the terms of this Indenture
and of such Securities and any coupons appertaining thereto.

                  (b) Such defeasance or covenant defeasance shall not result in
a breach or violation of, or constitute a default under, this Indenture or any
other material agreement or instrument to which the Company is a party or by
which it is bound.

                  (c) No Event of Default or event which with notice or lapse of
time or both would become an Event of Default with respect to such Securities
and any coupons appertaining thereto shall have occurred and be continuing on
the date of such deposit or, insofar as Sections 501(5) and 501(6) are
concerned, at any time during the period ending on the 91st day after the date
of such deposit (it being understood that this condition shall not be deemed
satisfied until the expiration of such period).

Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (ii) since the date of execution of this Indenture, there
has been a change in the applicable Federal income tax law, in either case to
the effect that, and based thereon such opinion shall confirm that, the Holders
of such Outstanding Securities and any coupons appertaining thereto will not
recognize income, gain or loss for Federal income tax purposes as a result of
such defeasance and will be subject to 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 had not occurred.

                  (e) In the case of an election under Section 1403, the Company
shall have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Outstanding Securities and any coupons appertaining thereto will
not recognize income, gain or loss for Federal income tax purposes as a result
of such covenant defeasance and will be subject to Federal income tax on the
same amounts, in the same manner and at the same times as would have been the
case if such covenant defeasance had not occurred.

                  (f) The Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that all
conditions precedent to the defeasance under Section 1402 or the covenant
defeasance under Section 1403 (as the case may be) have been complied with and
an Opinion of Counsel to the effect that either (i) as a result of a deposit
pursuant to subsection (a) above and the related exercise of the Company's
option under Section 1402 or Section 1403 (as the case may be), registration is
not required under the Investment Company Act of 1940, as amended, by the
Company with respect to the trust funds representing such deposit or by the
Trustee for such trust funds or (ii) all necessary registrations under said Act
have been effected.

                  (g) Notwithstanding any other provisions of this Section, such
defeasance or covenant defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations which may be imposed
on the Company in connection therewith.

                  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
respect of any Outstanding Securities of any series and any coupons appertaining
thereto shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and any coupons appertaining thereto and this
Indenture, to the payment, either directly or through any Paying Agent as the
Trustee may determine, to the Holders of such Securities and any coupons
appertaining thereto of all sums due and to become due thereon in respect of
principal (and 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.

                  Unless otherwise specified with respect to any Security
pursuant to Section 301, 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 currency or
currency unit 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 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 currency or currency unit in effect (as
nearly as feasible) at the time of the Conversion Event.

subject to Section 606, the Trustee shall deliver or pay to the Company from
time to time upon the Company 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.

                  SECTION 1505. Determination of Voting Rights; Conduct and
Adjournment of Meetings. (a) Notwithstanding any provisions of this Indenture,
the Trustee may make such reasonable regulations as it may deem advisable for
any meeting of Holders of Securities of a series in regard to proof of the
holding of Securities 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 vote,

appropriate. Except as otherwise permitted or required by any such regulations,
the holding of Securities shall be proved in the manner specified in Section 104
and the appointment of any proxy shall be proved in the manner specified in
Section 104 or by having the signature of the Person executing the proxy
witnessed or guaranteed by any trust company, bank or banker authorized by

be presumed valid and genuine without the proof specified in Section 104 or
other proof.

temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities provided in Section 1502(b), in which
case the Company 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
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

proxy shall be 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.

The 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 meeting and one such copy shall be delivered to the
Company 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.

request, demand, authorization, direction, notice, consent, waiver or other Act
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 an agent duly appointed in
writing; and, except as herein otherwise expressly provided, such Act shall
become effective when such instrument or instruments are delivered to the
Trustee. Proof of 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 Company, 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 accordance with such reasonable rules and regulations as may be

                  SECTION 1602. Liquidation; Dissolution; Bankruptcy. Upon any
distribution to creditors of the Company in a liquidation or dissolution of the
Company or in a bankruptcy, reorganization, insolvency, receivership or similar
proceeding relating to the Company or its property:

                          (1) Holders of Senior Debt shall be entitled to
                  receive payment in full in cash of the principal of (and
                  premium or Make-Whole Amount, if any) and interest (including
                  interest accruing after the commencement of any such
                  proceeding) to the date of payment on the Senior Debt before
                  Holders shall be entitled to receive any payment of principal
                  of or interest on Securities;

                          (2) Until the Senior Debt is paid in full in cash, any
                  distribution to which Holders would be entitled but for this
                  Article shall be made to holders of Senior Debt as their
                  interests may appear, except that Holders may receive
                  securities that are subordinated to Senior Debt to at least
                  the same extent as the Securities; and

                          (3) the Trustee is entitled to rely upon an order or
                  decree of a court of competent jurisdiction or a certificate
                  of a bankruptcy trustee or other similar official for the
                  purpose of ascertaining the persons entitled to participate in
                  such distribution, the holders of Senior Debt and other
                  Company debt, the amount thereof or payable thereon and all
                  other pertinent facts relating to the Trustee's obligations
                  under this Article Sixteen.

                  SECTION 1603. Default on Senior Debt. The Company may not pay
principal of or interest on the Securities and may not acquire any Securities
for cash or property other than capital stock of the Company if:

                          (1) a default on Senior Debt occurs and is continuing
                  that permits Holders of such Senior Debt to accelerate its
                  maturity, and


                                      -67-
<PAGE>

                          (2) the default is the subject of judicial proceedings
                  or the Company receives a notice of the default from a person
                  who may give it pursuant to Section 1611. If the Company
                  receives any such notice, a similar notice received within
                  nine months thereafter relating to the same default on the
                  same issue of Senior Debt shall not be effective for purposes
                  of this Section.

                  The Company may resume payments on the Securities and may
acquire them when:

                  (a) the default is cured or waived, or

                  (b) 120 days pass after the notice is given if the default is
not the subject of judicial proceedings.

if this Article otherwise permits the payment or acquisition at that time.

Securities is accelerated because of an Event of Default, the Company shall
promptly notify Holders of Senior Debt of the acceleration. The Company may pay
the Securities when 120 days pass after the acceleration occurs if this Article
permits the payment at that time.

                  SECTION 1605. When Distribution Must Be Paid Over. If a
distribution is made to Holders that because of this Article should not have
been made to them, the Holders who receive the distribution shall hold it in
trust for Holders of Senior Debt and pay it over to them as their interests may
appear.

                  SECTION 1606. Notice by Company. The Company shall promptly
notify the Trustee and any Paying Agent of any facts known to them that would
cause a payment of principal of or interest on Securities to violate this
Article.

                  SECTION 1607. Subrogation. After all Senior Debt is paid in
full and until the Securities are paid in full, Holders shall be subrogated to
the rights of Holders of Senior Debt to receive distributions applicable to
Senior Debt to the extent that distributions otherwise payable to the Holders
have been applied to the payment of Senior Debt. A distribution made under this
Article to Holders of Senior Debt which otherwise would have been made to
Holders is not, as between the Company and Holders, a payment by the Company on
Senior Debt.

                  SECTION 1608. Relative Rights. This Article defines the
relative rights of Holders and Holders of Senior Debt. Nothing in this Indenture
shall:

                          (1) impair, as between the Company and Holders, the
                  obligation of the Company, which is absolute and
                  unconditional, to pay principal of and interest on the
                  Securities in accordance with their terms;

                          (2) affect the relative rights of Holders and
                  creditors of the Company other than Holders of Senior Debt; or

                          (3) prevent the Trustee or any Holder from exercising
                  its available remedies upon an Event of Default, subject to
                  the rights of Holders of Senior Debt to receive distributions
                  otherwise payable to Holders.

                  If the Company fails because of this Article to pay principal
of or interest on a Security on the due date, the failure is still a default.

<PAGE>

                  SECTION 1609. Subordination May Not Be Impaired By Company. No
right of any Holder of Senior Debt to enforce the subordination of the
indebtedness evidenced by the Securities shall be impaired by any act or failure
to act by the Company or by its failure to comply with this Indenture.

                  SECTION 1610. Distribution or Notice to Representative.
Whenever a distribution is to be made or a notice given to Holders of Senior
Debt, the distribution may be made and the notice given to their Representative.

                  SECTION 1611. Rights of Trustee and Paying Agent. The Trustee
or any Paying Agent may continue to make payments on the Securities until it
receives written notice of facts that would cause a payment of principal of or
interest on the Securities to violate the Article. Only the Company, a
Representative or a Holder of an issue of Senior Debt that has no Representative
may give the written notice.

                  The Trustee has no fiduciary duty to the Holders of Senior
Debt other than as created under this Indenture. The Trustee in its individual
or any other capacity may hold Senior Debt with the same rights it would have if
it were not Trustee.

                  The Company's obligation to pay, and the Company's payment of,
the Trustee's fees pursuant to Section 606 are excluded from the operation of
this Article Sixteen.

                                  ************

                  This Indenture may be executed in any number of counterparts,
each of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same Indenture.

purchase Common Stock (the "Common Stock Warrants") and (v) shares of Preferred
Stock represented by depositary shares ("Depositary Shares" and, together with
the Debt Securities, Preferred Stock, Common Stock and Common Stock Warrants,

to time as set forth in the prospectus which forms a part of the Registration

and a financial institution identified therein as a warrant agent (each, a
"Warrant Agent"), (iii) prior to any issuance of shares of Preferred Stock or
Depositary Shares, appropriate articles supplementary shall be filed for
recordation with the State Department of Assessment and Taxation of the State of
Maryland (each, "Articles Supplementary") and (iv) any Depositary Shares will be

                       Assessment and Taxation of the State of Maryland on
                       April 17, 1998 and by an Assistant Secretary of the
                       Company on the date hereof as then being complete,
                       accurate and in effect.

                  3.   The Second Amendment and Restatement of Bylaws of the
                       Company, as amended, as certified by an Assistant

                  In our examination of the aforesaid documents, we have assumed
the genuineness of all signatures, the legal capacity of natural persons, the
accuracy and completeness of all documents submitted to us, the authenticity of
all original documents, and the conformity to authentic original documents of
all documents submitted to us as copies (including telecopies). This opinion
letter is given, and all statements herein are made, in the context of the
foregoing.

                  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), 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, 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 creditors' rights (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 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 shares of
         Preferred Stock will be validly issued, fully paid and non-assessable.

                  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 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 non-assessable.

                  4. When the Registration Statement has become effective under
         the Act and when the Common Stock Warrants have been (a) duly
         established by 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 Common Stock
         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 creditors' rights (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
         Common Stock Warrants are considered in a proceeding in equity or at
         law).

                  5. When the Registration Statement has become effective under
         the Act and when a series of Preferred Stock underlying a series of
         Depositary Shares has been classified by applicable Board Action, in
         accordance with the terms of the Articles and applicable law, and
         appropriate Articles Supplementary have been filed with respect to such
         shares of Preferred Stock, and the execution and delivery of a Deposit
         Agreement have been appropriately authorized by applicable Board
         Action, and when the depositary receipts representing the Depositary
         Shares (the "Depositary Receipts") in the form contemplated and

         authorized by a Deposit Agreement have been duly executed and delivered
         by the Depositary against payment of valid consideration therefor in
         accordance with the terms of the Deposit Agreement and any applicable
         underwriting or purchase agreement, and as contemplated by the
         Registration Statement and/or the applicable Prospectus Supplement,
         such Depositary Shares will be validly issued.

                  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 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.

         To the extent that the obligations of the Company and the rights of any
holder of Depositary Shares under any Deposit Agreement may be dependent upon
such matters, we assume for purposes of this opinion that the applicable
Depositary is duly organized, validly existing and in good standing under the
laws of its jurisdiction of organization; that the Depositary is duly qualified
to engage in the activities contemplated by the Deposit Agreement; that the
Deposit Agreement has been duly authorized, executed and delivered by the

Depositary and constitutes a valid and binding obligation of the Depositary
enforceable against the Depositary and the Company in accordance with its terms;
that the Depositary is in compliance, with respect to acting as a Depositary
under the Deposit Agreement, with all applicable laws and regulations; and that
the Depositary has the requisite organizational and legal power and authority to
perform its obligations under the Deposit Agreement.

                  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.

                  We assume no obligation to advise you of any changes in the
foregoing subsequent to the delivery of this opinion letter. This opinion letter
has been prepared solely for your use in connection with the filing of the
Registration Statement on the date of this opinion letter and should not be
quoted in whole or in part or otherwise be referred to, nor filed with or
furnished to any governmental agency or other person or entity, without the
prior written consent of this firm.

                  We hereby consent to the filing of this opinion letter as an
exhibit to the Registration Statement and to the reference to this firm under
the caption "Legal Matters" in the prospectus constituting a part of the
Registration Statement. In giving this consent, we do not thereby admit that we
are an "expert" within the meaning of the Act.

CarrAmerica Realty Corporation

Washington D.C.   20006


Ladies and Gentlemen:

                  We have acted as counsel to CarrAmerica Realty Corporation, a
Maryland corporation (the "Company"), in connection with the registration of
unsecured debt securities ("Debt Securities"), preferred stock ("Preferred
Stock"), common stock, $.01 per value ("Common Stock"), warrants exercisable for
Common Stock ("Common Stock Warrants") and shares of preferred stock represented
by depositary shares ("Depositary Shares") of the Company, with an aggregate
public offering price of up to $1,000,000,000, as more fully described in the
Company's Registration Statement filed with the Securities and Exchange
Commission on or about the date hereof ("Registration Statement," which includes
the "Prospectus"). In connection with such registration, we have been asked to
provide you with an opinion regarding certain federal income tax matters related
to the Company. Capitalized terms used in this letter and not otherwise defined
herein have the meaning set forth in the Prospectus.

                  Basis for Opinion

                  The opinion set forth in this letter is based on relevant
provisions of the Code, Treasury Regulations thereunder (including proposed and
temporary Regulations), and interpretations of the foregoing as expressed in
court decisions, the legislative history, and existing administrative rulings
and practices of the Internal Revenue Service ("IRS") (including its practices
and policies in issuing private letter rulings, which are not binding on the IRS
except with respect to a taxpayer that receives such a ruling), all as of the
date hereof. These provisions and interpretations are subject to change, which
may or may not be retroactive in effect, that might result in modifications of
our opinion.

                  In rendering our opinion, we have examined the following
documents: (1) the Prospectus and the Prospectus Supplement; (2) the Proxy
Statement filed with the Securities and Exchange Commission on November 6, 1995
(the "Proxy Statement"); (3) the Stock Purchase Agreement dated as of November

<PAGE>


5, 1995 among the Company, Security Capital U.S. Realty, a Luxembourg
corporation ("SC-USREALTY"), Security Capital Holdings S.A., a Luxembourg
corporation and a wholly-owned subsidiary of SC-USREALTY ("Holdings"), as
amended as of April 29, 1996 (the "Stock Purchase Agreement"); (4) the
Stockholders Agreement dated as of April 30, 1996 among the Company, Carr
Realty, L.P., SC-USREALTY, and Holdings (the "Stockholders Agreement"); (5) the
Registration Rights Agreement dated as of April 30, 1996 among the Company,
SC-USREALTY and Holdings (the "Registration Rights Agreement"); (6) the articles
of incorporation and stock ownership records or partnership agreement (as
applicable) of each of the Company, Carr Realty, L.P., CarrAmerica Development,
Inc. (the "Development Company"), Carr Real Estate Services, Inc. ("Carr
Services, Inc."), CarrAmerica Realty Services, Inc. ("CarrAmerica Services,
Inc."), Carr Redmond Corporation, Carr Real Estate Services Partnership ("Carr
Services, L.P."), CarrAmerica Realty L.P., Carr Parkway North I Corporation
("Carr Parkway North"), CarrAmerica Realty GP Holdings, Inc. ("Carr GP
Holdings"), CarrAmerica Realty LP Holdings, Inc. ("Carr LP Holdings"),
OmniOffices, Inc. ("OmniOffices") and CarrAmerica Realty Properties, Inc. ("Carr
Properties"). (Collectively, the above-referenced entities are sometimes
referred to herein as the "Company Group Entities.") The opinion set forth in
this letter also is premised on certain written representations of the Company
contained in a letter dated April 7, 1998 (the "Management Representation
Letter").

                  We have made such factual and legal inquiries, including
examination of the documents set forth above, as we have deemed necessary or
appropriate for purposes of our opinion. For purposes of rendering our opinion,
however, we have not made an independent investigation or audit of the facts set
forth in the above referenced documents, including the Prospectus, the
Prospectus Supplement and the Management Representation Letter. We consequently
have relied upon the representations in the Management Representation Letter
that the information presented in such documents or otherwise furnished to us is
accurate and assumed that the information presented in such documents or
otherwise furnished to us is accurate and complete in all material facts
relevant to our opinion.

                  In our review, we have assumed that all of the representations
and statements set forth in the documents (including, without limitation, the
Management Representation Letter) we reviewed are true and correct, and all of
the obligations imposed by any such documents on the parties thereto, including
obligations imposed under the Company Articles of Incorporation, have been and
will be performed or satisfied in accordance with their terms. We also have
assumed the genuineness of all signatures, the proper execution of all
documents, the authenticity of all documents submitted to us as originals, the
conformity to originals of documents submitted to us as copies, and the
authenticity of the originals from which any copies were made. Moreover, we have
assumed that each of the Company Group Entities has been and will continue to be
operated in the manner described in the relevant partnership agreement, articles
(or certificate) of incorporation or other organizational documents and in the
Prospectus and the Prospectus Supplement and that, as represented by the

<PAGE>

Company, (i) there are no agreements or understandings between the Company or
Carr Realty, L.P., on the one hand, and The Oliver Carr Company ("OCCO") and/or
its shareholders, on the other, that are inconsistent with OCCO being considered
to be both the record and beneficial owner of more than 90% of the outstanding
voting stock of each of the Development Company and Carr Services, Inc. and (ii)
there are no agreements or understandings between the Company on the one hand,
and any of (x) SC-USREALTY, (y) OCCO and/or its shareholders, or (z) Strategic
Omni Investors, LLC or the owners thereof, on the other, that are inconsistent
with (x) SC-USREALTY, (y) OCCO and (z) Strategic Omni Investors LLC being
considered to be both the record and beneficial owner of all of the outstanding
voting stock of OmniOffices.

                  We assume for the purposes of this opinion that the Company is
a validly organized and duly incorporated corporation under the laws of the
State of Maryland, that the Development Company, Carr Services, Inc.,
CarrAmerica Services, Inc., Carr Redmond Corporation, Carr Parkway North, Carr
GP Holdings, Carr LP Holdings, OmniOffices and Carr Properties are validly
organized and duly incorporated corporations under the laws of the State of
Delaware, and that Carr Realty, L.P., Carr Services, L.P., and CarrAmerica
Realty, L.P. are duly organized and validly existing partnerships under the
applicable laws of the State of Delaware.

Opinion

                  Based upon, subject to, and limited by the assumptions and
qualifications set forth herein, we are of the opinion that:

                  1. The Company was organized and has operated in conformity
with the requirements for qualification and taxation as a real estate investment
trust ("REIT") under the Code for its taxable years ended December 31, 1993,
December 31, 1994, December 31, 1995, December 31, 1996, and December 31, 1997
and the Company's current organization and method of operation should enable it
to continue to meet the requirements for qualification and taxation as a REIT.

                  2. The discussions in the Prospectus and the Prospectus
Supplement under the headings "Federal Income Tax Considerations," to the extent
that they describe matters of federal income tax law, are correct in all
material respects.

                  We assume no obligation to advise you of any changes in our
opinion subsequent to the delivery of this opinion letter. The Company's
qualification and taxation as a REIT depends upon the Company's ability to meet
on a continuing basis, through actual annual operating and other results, the
various requirements under the Code with regard to, among other things, the
sources of its gross income, the composition of its assets, the level of its

<PAGE>

distributions to stockholders, and the diversity of its stock ownership. We will
not review the Company's compliance with these requirements on a continuing
basis. Accordingly, no assurance can be given that the actual results of the
operations of the Company, Carr Realty, L.P., CarrAmerica Realty, L.P. and the
other Company Group Entities, the sources of their income, the nature of their
assets, the level of the Company's distributions to its stockholders and the
diversity of the Company's stock ownership for any given taxable year will
satisfy the requirements under the Code for qualification and taxation as a
REIT.

                  An opinion of counsel merely represents counsel's best
judgment with respect to the probable outcome on the merits and is not binding
on the IRS or the courts. There can be no assurance that positions contrary to
our opinion will not be taken by the IRS or that a court considering the issues
would not hold contrary to such opinion.

                  This opinion letter has been prepared solely for your benefit
in connection with the filing of the Registration Statement. This opinion may
not be used or relied upon by any other person or for any other purpose and may
not be disclosed, quoted, or filed with a governmental agency or otherwise
referred to without our prior written consent. We hereby consent to the filing
of this opinion letter as Exhibit 8.1 to the Registration Statement and to the
reference to this firm under the caption "Legal Matters" in the Prospectus. In
giving this consent, we do not thereby admit that we are an "expert" within the
meaning of the Securities Act of 1933, as amended.

                                                              Very truly yours,


                                                      /s/ Hogan & Hartson L.L.P.
