                                     PART I

ITEM 1.   BUSINESS.

     Charles E. Smith Residential Realty L.P., a Delaware limited partnership
(the "Operating Partnership"), was formed in 1993 and commenced operations on
June 30, 1994.  It is managed by its general partner, Charles E. Smith
Residential Realty, Inc., a Maryland corporation (the " Company"), which is a
self-administered and self-managed equity real estate investment trust ("REIT").
The Company was organized in 1993 and also commenced operations on June 30, 1994
upon completion of its initial public offering (the "Initial Public Offering").

The Operating Partnership and the Company are engaged primarily in the
acquisition, development, management and operation of multifamily properties.
The Operating Partnership, together with the Company and their respective
subsidiaries as described below, is a fully integrated real estate organization
with in-house acquisition, development, financing, marketing, leasing and
property management expertise. The Operating Partnership's primary strategy for
growth is to acquire, develop, own and manage high quality multifamily
properties for income generation and long-term value appreciation.

     The Company is the sole general partner and holds approximately 56% of the
common and preferred units of limited partnership interest ("Units") in the
Operating Partnership as of March 2, 1998. The other limited partners of the
Operating Partnership (the "Minority Interest") primarily consist of the former
limited and general partners of properties and the former owners of the property
service businesses acquired by the Operating Partnership (see "History of the
Company" below). The Operating Partnership and its subsidiaries own all of the
properties, property interests, and business assets and conduct all operations
on behalf of the Company and the Operating Partnership. The Operating 
Partnership owns 100% of the nonvoting common

                                       1
<PAGE>
 
stock, which represents 99% of the total economic interest, of three operating
companies (collectively, the "Property Service Businesses") which provide
property services to the properties owned by the Operating Partnership and to
other multifamily, retail, and office properties. The three Property Service
Businesses are: Smith Realty Company, which provides management, leasing,
financing, development and insurance services; Consolidated Engineering
Services, Inc., which provides engineering and technical services; and Smith
Management Construction, Inc., which provides construction and interior
renovation services. As the sole general partner of the Operating Partnership,
the Company has the exclusive power to manage and conduct the business of the
Operating Partnership, subject to the consent of the holders of Units in
connection with the sale of all or substantially all of the assets of the
Operating Partnership. Some references made herein to the Company include the
Operating Partnership and the Property Service Businesses, as the context
requires.

     As of March 2, 1998, the Operating Partnership, directly or through its
subsidiaries, owned 46 operating multifamily apartment properties containing a
total of 18,296 units (the "Multifamily Properties"),  two retail centers
containing approximately 436,000 square feet of retail space (the "Retail
Properties"), and had three properties under construction containing
approximately 2,000 units  ("Development Properties").  All properties,
excluding two in Chicago, Illinois and one in Boston, Massachusetts, are located
in the Washington, D.C. metropolitan area (collectively, the "Properties").

     The executive offices of the Operating Partnership and the Company are
located at 2345 Crystal Drive, Crystal City, Arlington, Virginia 22202, and its
telephone number is (703) 920-8500.


HISTORY OF THE COMPANY

     The Operating Partnership was formed to succeed to the property assets of
38 partnerships (the "Property Partnerships") and certain asset management and
property service businesses of the Charles E. Smith Companies (the "Smith
Companies").  On June 30, 1994, the Company consummated an initial public
offering (the "Initial Public Offering") of 8,632,800 shares of its common
stock, $.01 par value per share (the "Common Stock"), and a private placement of
416,667 shares of its Common Stock.  The Company contributed the net proceeds of
such offerings to the Operating Partnership in return for 9,049,467 Units of
general and limited partnership interest therein.  On that same date, (i) the
Operating Partnership acquired, in exchange for 12,131,292 Units, 30  Properties
(reflects the combination of  three buildings into one for operational and
statistical purposes), partial interests in two additional properties, all of
the non-voting common stock of the Property Service Businesses (representing 99%
of the economic interest), and notes of the Property Service Businesses in the
aggregate amount of $44.5 million; (ii) the Operating Partnership, through its
partnership subsidiaries, issued $352.4 million of fixed-rate indebtedness
secured by certain of the Properties in private placements to institutional
investors and assumed certain other indebtedness (the "Mortgage Loans"); (iii)
the Operating Partnership applied the proceeds of the Mortgage Loans and the
Company's contribution of offering proceeds to repay approximately $454 million
of mortgage indebtedness,

                                       2
<PAGE>
 
$26.2 million in related party indebtedness and $11.1 million in notes payable
to a bank, to pay $13.8 million in prepayment penalties related to the early
extinguishment of debt, to pay $14.7 million in transfer taxes and other costs
associated with the formation of the Company and the Operating Partnership, and
to pay $18.5 million of mortgage recording taxes, origination fees and other
expenses associated with the Mortgage Loans, and to supply $15.4 million of
working capital; and (iv) the Operating Partnership established a $100 million
line of credit to fund development activities and property acquisitions and for
general corporate purposes (collectively, the "Formation Transactions").

     Since the Formation Transactions and through March 2, 1998, the Operating
Partnership developed one and acquired 18 operating Multifamily Properties
totaling 6,688 apartment units and sold one property containing 227 units. In
addition, the Operating Partnership had approximately 2,000 units under
construction at three Development Properties as of March 2, 1998 (see "Recent
Developments" below).

BUSINESS STRATEGY

     The Operating Partnership seeks growth in funds from operations (a common
measure of equity real estate investment trust performance, defined as net
income [loss] computed in accordance with generally accepted accounting
principles, excluding gains or losses from debt restructuring and sales of
property plus depreciation and amortization of assets unique to the real estate
industry) while preserving and enhancing property values by pursuing the
following strategies: (i) maximizing cash flow from operations of the Properties
by seeking to maintain high occupancy levels, obtain rent increases, manage
tenant turnover efficiently, make strategic capital investments, expand the
availability of furnished rental apartments, initiate new tenant fees and
control operating expenses; (ii) acquiring additional multifamily properties for
Common Stock, Units, or cash in situations where, in the judgment of management,
the Operating Partnership's business strengths have the potential to increase
property performance and value; (iii) developing new multifamily properties
consistent with the predecessor Smith Companies' historical policies of
constructing and maintaining high quality properties for long-term income and
value enhancement; and (iv) actively promoting the comprehensive property
services of the Property Service Businesses to unaffiliated property owners.  In
addition to its activities in the Washington, D.C. metropolitan area, the
Operating Partnership also seeks to acquire additional properties or portfolios
in Chicago, Boston and other markets with characteristics similar to the
Operating Partnership's current portfolio that offer opportunities for
profitable investment and long-term growth.

FINANCING STRATEGY

     To the extent that the Company's board of directors determines to seek
additional capital for acquisitions or otherwise, the Company or the Operating
Partnership may raise such capital through additional equity offerings, debt
financing or retention of cash flow (subject to provisions of  the Internal
Revenue Code of 1986, as amended, requiring the distribution by a REIT of a
certain percentage of taxable income and taking into account taxes that would be
imposed on undistributed taxable income), or a combination of these methods.

                                       3

EQUITY

During 1997 and through March 2, 1998, the Company and the Operating Partnership
completed several equity transactions.

     On February 19, 1997, the Company consummated a second stock offering,
issuing an additional 3,105,000 shares of Common Stock (including exercise of
the underwriter's over-allotment), and the proceeds of such offering were used
to purchase an additional 3,105,000 common units in the Operating Partnership.

     On May 15, 1997, the Company entered into an agreement with Security
Capital Preferred Growth, Inc. ("Security Capital") to sell  2,640,325 shares by
May 14, 1998 of Series A Cumulative Convertible Redeemable Preferred Stock
("Series A Preferred Shares"), $0.01 par value.  On June 30, 1997 and December
2, 1997, the Company sold 738,553 and 923,191 Series A Preferred Shares,
respectively, under the agreement.  The net proceeds were contributed to the
Operating Partnership in exchange for 1,661,744 Series A Cumulative Redeemable
Preferred Units ("Series A Preferred Units").

     The Operating Partnership amended the Articles of  Incorporation to
designate and establish the rights and privileges of the Series A Preferred
Unitholders which include certain voting, distribution and liquidation
preferences. Distributions are cumulative from the date of original issue and
are payable quarterly at the greater of the rate declared on the common unit or
an annual rate of $2.02 per unit. The Series A Preferred Units are not
redeemable prior to May 15, 2003. On or after May 15, 2003, the Operating
Partnership, at its option, may redeem the Series A Preferred Units for cash at
a price of $27.08 per unit, plus accrued and unpaid distributions. Under certain
circumstances, the Operating Partnership may elect to make such redemption with
Common Unit at the then market price of the Company's Common Stock. On or after
January 31, 1999, Security Capital may convert the Series A Preferred Shares
into Common Stock on a one-for-one basis subject to certain limitations. Prior
to January 31, 1999, the Series A Preferred Shares will not be convertible
unless the Company undergoes a change in control, as defined by the agreement,
or fails to qualify as a REIT for tax purposes.

     On October 3, 1997, the Company sold 1,450,000 shares of Common Stock and
1,216,666 shares of Series B Cumulative Convertible Redeemable Preferred Stock
("Series B Preferred Shares"), $0.01 par value, to the Prudential Insurance
Company of America ("Prudential").  The net proceeds were contributed to the
Operating Partnership in exchange for 1,450,000 common units and 1,216,666
Series B Cumulative Redeemable Preferred Units ("Series B Preferred Units").

     The Operating Partnership amended the Articles of Incorporation to
designate and establish the rights and privileges of the Series B Preferred
Unitholders which include certain voting, distribution and liquidation
preferences over the common unitholders. The Series B Preferred Units have a
liquidation preference of $28.50 per unit. Distributions are cumulative

                                       4
<PAGE>
 
and are payable quarterly at the greater of the rate declared on the common unit
or an annual rate of $2.02 per unit. Prudential may convert the Series B
Preferred Shares into shares of Common Stock on a one-for-one basis, subject to
certain adjustments and limitations related to its ownership of Common Stock of
the Company. The Company, at its option, may redeem Series B Preferred Shares at
any time for Common Stock, plus accrued and unpaid dividends.

     In January 1998, the Company sold 500 shares of Series C Cumulative
Redeemable Preferred Stock ("Series C Preferred Shares"), $0.01 par value, to
Cobalt Capital, LLC.  The Company contributed the net proceeds to the Operating
Partnership in exchange for 500 shares of Series C Cumulative Redeemable
Preferred Units ("Series C Preferred Units").

     The Operating Partnership amended the Articles of Incorporation to
designate and establish the rights and privileges of the Series C Preferred
Unitholders which include certain voting, distribution and liquidation
preferences over the common unitholders.  The Series C Preferred Units have a
liquidation preference of $100,000 per unit and an initial annual distribution
of $7,910 per unit (7.91% of purchase price).  If the securities receive an
investment grade rating, the distribution  will  decrease to $7,660 per unit.
Distributions are cumulative and are payable quarterly.  The Operating
Partnership may redeem Series C Preferred Units after February 1, 2028, at the
liquidation price plus accrued distributions.

     The Company currently has on file with the Securities and Exchange
Commission an effective registration statement which allows the sale of up to
$450,000,000 in debt or equity securities, of which approximately $312,000,000
remains available. As long as the Operating Partnership is in existence, the net
proceeds of all equity capital raised by the Company will be contributed to the
Operating Partnership in exchange for limited partnership interests in the
Operating Partnership.  The Company and the Operating Partnership also may issue
securities senior to the Common Stock or Units, including additional preferred
stock or debt securities (either of which may be convertible into Common Stock
or Units or may be accompanied by warrants to purchase Common Stock or Units).

DEBT

     The Operating Partnership's policy, which is set by the Board of Directors
of the Company, is to incur debt (including debt incurred under its lines of
credit) only if upon such incurrence its ratio of debt to total market
capitalization would be 60% or less. The Operating Partnership may reevaluate or
modify this financing policy from time to time in light of then current economic
conditions, relative costs of debt and equity capital, market values of
properties, growth and acquisition opportunities and other factors.  At December
31, 1997, the Operating Partnership's debt to total market capitalization ratio
was 35.0%.

PROPERTY MANAGEMENT

     The Operating Partnership  and its Property Service Businesses are
experienced in the management and leasing of multifamily and retail properties.
The Operating Partnership believes that the management and leasing of its own
portfolio has resulted in consistent income growth

                                       5
<PAGE>
 
and reduced operating expenses. The Property Service Businesses have provided
the Operating Partnership both with a source of cash flow that is relatively
stable and with economies of scale in conjunction with the management and
leasing of its own Properties. These Property Service Businesses also allow the
Operating Partnership and its subsidiaries to establish additional relationships
with tenants that benefit the Properties.

PROPERTY SERVICE BUSINESSES

     MULTIFAMILY PROPERTY MANAGEMENT SERVICES.  The residential property
management business of Smith Realty Company ("SRC"), an operating subsidiary of
the Operating Partnership, is a long-established, integrated business with
extensive experience in leasing and managing multifamily properties. This
subsidiary has been managing and leasing multifamily housing in the Washington,
D.C. metropolitan area since 1946 and, as of March 2, 1998, manages 58 apartment
properties (including 45 Multifamily Properties and 13 other multifamily
properties with approximately 3,800 apartment units). It also assists in the
development and acquisition of additional multifamily properties and carries out
a periodic inspection program that addresses all aspects of the property and
property management.

     RETAIL PROPERTY MANAGEMENT SERVICES.  The retail management and leasing
business, also conducted through Smith Realty Company, approaches the management
and leasing of its retail portfolio with an integrated program of regular direct
communication with retail tenants, proactive assistance with marketing,
merchandising and monitoring store operations, and maintenance. A retail
marketing staff works to promote the shopping centers as a whole and to work
with individual tenants to ensure the effectiveness of store design, marketing,
merchandising and sales efforts. The retail management and leasing group, in
addition to providing complete property management and leasing services for the
two Retail Properties totaling approximately 436,000 square feet, also provides
such services for a fee to three retail properties owned by affiliated parties
totaling approximately 293,000 square feet, and one retail property owned by an
unaffiliated third party totaling 660,000 square feet. Smith Realty Company also
provides retail leasing and brokerage services for additional, unaffiliated
third parties on a fee-for-service basis.
 
          FINANCING SERVICES.  The finance department negotiates and administers
all debt financing for the Operating Partnership and its subsidiaries, and, for
a fee, other properties owned by third parties (the majority of which are
affiliated with Robert H. Smith and Robert P. Kogod, the Co-Chief Executive
Officers and Co-Chairmen of the Board of the Company and the owners of
approximately 13% of the shares and Units).  This responsibility includes
obtaining new sources of funding by actively soliciting prospective lenders,
monitoring, analyzing and negotiating changes in loan status and/or structure,
and satisfying reporting requirements of lenders. Financing services were
performed for approximately $489 million of refinancing in 1997. During the
fourth quarter of 1997, Financing Services personnel transferred to  Charles E.
Smith Commercial Realty L.P. ("CESCR"),  a commercial office partnership
affiliated with Messrs. Smith and Kogod.  The Operating Partnership entered into
agreements through December 31, 1998 to provide Financing Services for certain
properties owned and certain properties to be acquired by CESCR.  Services will
be provided utilizing CESCR personnel on

                                       6
<PAGE>
 
a negotiated cost basis. The Company will separately negotiate revenue and cost
sharing agreements for Financing Services it may provide, if any, to properties
managed but not owned by CESCR.

     ENGINEERING AND TECHNICAL SERVICES.  The engineering and technical services
business is conducted through Consolidated Engineering Services, Inc., an
operating subsidiary of the Operating Partnership, which manages, operates,
maintains and repairs the "physical plant" of office, multifamily, and retail
properties.  Through its staff of on-site and off-site engineers, supervisors,
technical specialists and maintenance personnel, this subsidiary provides
various services, including on-site building systems operations and maintenance,
engineering and technical consulting, automated environmental monitoring and
controls, preventive maintenance, management of building environmental systems
and repair and replacement of mechanical/electrical systems.  This business
serves the Properties and also provides facilities management services for both
affiliated and unaffiliated third parties, including condominium, bank,
university and government buildings. During 1997, services were provided with
respect to approximately 30 million square feet of facilities.

     INTERIOR CONSTRUCTION AND RENOVATION SERVICES.  The construction services
business, conducted through Smith Management Construction, Inc., an operating
subsidiary of the Operating Partnership, is a construction management and
general contracting company that provides interior construction and renovation
services to the Properties and various other affiliated and unaffiliated third
party clients.  This business focuses primarily on capital improvement projects
and office and retail tenant space construction and alteration, and provides the
expertise necessary to take a project from the initial planning and
preconstruction stage through the completion of construction. In 1997, oversight
was provided to approximately $66 million of construction activity.

     CORPORATE SERVICES. The corporate services businesses, conducted through
Smith Realty Company, enable a central office to provide supporting services in
the areas of  insurance, legal advice, accounting, information systems, human
resources, office  administration and marketing to the Operating Partnership
and its subsidiaries, as well as to other affiliated third parties, including
CESCR. Services are provided at cost (including overhead) in accordance with
cost and executive sharing agreements. In management's opinion, the allocation
methods provide reasonable estimates of the costs that would have been incurred
by the Operating Partnership had the services been provided by the Operating
Partnership.

     The accounting department is responsible for all accounting, auditing and
controls, procedures and management information systems as they relate to the
Operating Partnership and the Properties, and for certain other partnerships and
corporate entities (including affiliates of Messrs. Smith and Kogod). The legal
department provides real estate and corporate advice to management, performs
legal services and in some cases coordinates representation by outside counsel.
The marketing department develops and implements a variety of marketing programs
for the Operating Partnership and its subsidiaries, and for specific properties.
The human resources department administers all personnel functions.  The
insurance subsidiary provides

                                       7
<PAGE>
 
property and casualty insurance placement services for both corporate and
individual property requirements.

EMPLOYEES

     As of  March 2, 1998, the Operating Partnership and its subsidiaries had
approximately 1,400 full-time and part-time employees, the latter primarily
employed in on-site clerical positions.  This total includes 540 employees who
provide on-site property services and, in the Property Service Businesses, 550
persons in its engineering and technical services subsidiary, 110 persons in its
interior construction and renovation subsidiary, and 200 persons in its
residential and retail leasing and management, finance, and corporate services
subsidiary.

ITEM 2.   PROPERTIES

GENERAL

     The 51 Properties as of March 2, 1998 consist of 46 Multifamily Properties,
three Development Properties and two Retail Properties, as described in more
detail below. Twenty-eight of the Multifamily Properties (reflecting the
combination of three buildings into one for operational and statistical
purposes) and both Retail Properties were acquired in connection with the
Formation Transactions, two additional Multifamily Properties were acquired in
1994, five additional Multifamily Properties were acquired and one additional
Multifamily Property was constructed and delivered in 1995, four additional
Multifamily Properties were acquired in 1996

                                       12
<PAGE>
 
(one of which was later combined with another Property for operational and
statistical purposes), six operating Multifamily Properties were acquired in
1997, and three Development Properties (or interests therein) were acquired and
construction commenced in 1997. In addition, the Operating Partnership held a
minority limited partnership interest in one other multifamily property (after
giving effect to the January 1998 purchase of the remaining partnership interest
in Tunlaw Park) in the Washington metropolitan area, acquired in the Formation
Transactions and increased in a subsequent transaction.

     All of the Operating Partnership's properties are located in developed
areas that include other residential and retail properties.  The number of
competitive residential properties in a particular area could have a material
effect on the Operating Partnership's ability to lease apartment units and on
the rents charged.  In addition, other forms of single and multifamily
residential properties provide housing alternatives to tenants and potential
tenants of the Operating Partnership's residential properties.  The Operating
Partnership's  retail properties face similar competition with other retail
properties with respect to tenant leases.  The Operating Partnership believes
that the properties are well located in their markets and are well constructed
and designed.  In the opinion of management, the Operating Partnership's
properties are adequately covered by insurance.

MULTIFAMILY PROPERTIES

     The  45 operating Multifamily Properties owned as of December 31, 1997
contain a total of 18,236 garden, mid-rise, and high-rise apartment units,
ranging in size from 115 to 1,065 apartment units.  All properties are located
in the Washington D.C. metropolitan area with the exception of one property in
Chicago, Illinois and one property in Boston, Massachusetts.  All of the
Multifamily Properties are 100% owned by the Operating Partnership and its
subsidiaries. The Smith Companies developed and built 27 of the Multifamily
Properties owned by the Operating Partnership (not including the Westerly at
Worldgate, which was developed by the Operating Partnership but constructed by
an affiliate of the Smith Companies).  In 1997, the average monthly rental
revenue per unit was $901 and the average economic occupancy was 96.4% for the
Core Residential Portfolio (Multifamily Properties owned as of  December 31,
1995.)

     Each of the Multifamily Properties is established in its local market and
provides residents with numerous amenities and services, which may include 24-
hour desk service, swimming pools, tennis courts, exercise rooms and/or saunas,
day care centers, party or meeting rooms, tenant newsletters, and laundry
facilities. Nearly all units are wired for cable television, and many units also
offer additional features, such as washer/dryer, microwave, fireplace, and
patio/balcony. The Operating Partnership  maintains an ongoing program of
regular maintenance and capital improvements and renovations, including roof
replacement and exterior maintenance, kitchen and bath renovations, balcony
repairs, and replacements of various building systems.

     The following table sets forth certain additional information relating to
the Multifamily Properties as of December 31, 1997 (in the following table,
occupancy is based upon economic occupancy, which measures occupancy beginning
on the rent commencement date; monthly

RETAIL PROPERTIES

     The Operating Partnership's two Retail Properties, Skyline Mall and
Worldgate Centre, are enclosed malls containing a total of approximately 436,000
square feet of retail space.   Until December  1997, both Retail Properties
leased  health club facilities to entities controlled by Messrs. Smith and Kogod
pursuant to leases expiring on December 31, 2015.  In December 1997, the health
clubs were sold by Messrs. Smith and Kogod.  In conjunction with that sale, the
Operating Partnership agreed to restructure the two leases, including reduced
base rent on the Worldgate lease, and extend terms on both leases for ten years,
through 2025, in exchange for a $2.3 million cash payment.  The Operating 
Partnership used the funds to retire 65,000 Operating Partnership units.

     WORLDGATE CENTRE.  Worldgate Centre is a community retail center located in
Herndon, Virginia, at the intersection of two major Northern Virginia traffic
arteries, the Dulles Airport Access Highway and Centreville Road.  Developed by
the Smith Companies in 1991, it is a part of a mixed-use development which
includes the 320-unit Multifamily Property which the Operating Partnership
constructed  in 1995. The town of Herndon is located in Fairfax County, one of
the highest median income counties in the country. The Property contains the
108,670 square foot Worldgate Athletic Club, a Loew's Cinema, and a mix of
approximately 40 other food service, fashion and specialty retailers and various
business and general service tenants.  Worldgate Centre has 230,926 square feet
of leasable area and had an average occupancy rate of 97.6% during 1997.
Approximately 10.1% of the leases, based on net rentable area, are scheduled to
expire prior to the year 2001.

     SKYLINE MALL.  Skyline Mall is a two-level, enclosed community retail
center located on Route 7 in Northern Virginia, at the intersection of  Fairfax
County, Arlington County, and the City of Alexandria, Virginia. Originally
developed by the Smith Companies in 1977, it is part of a mixed-use community
which also includes over two million square feet of office space and over 3,300
high-

rise condominium and apartment units (including Skyline Towers, a 940-unit
Multifamily Property owned by the Operating Partnership), all within walking
distance.  The Property has 204,914 square feet of leasable area and had an
average occupancy rate of 97.2% in 1997.  It contains the 79,920 square foot
Skyline Racquet and Health Club, an AMC Cinema, and approximately 40 other
stores, including restaurants, fashion and specialty retailers, and various
business and general services. Approximately 11.8% of the leases, based on net
rentable area, are scheduled to expire prior to the year 2001.

PROPERTY MARKETS

     The Operating Partnership believes that the demographic and economic trends
and conditions in the Chicago, Boston and Washington, D.C. metropolitan areas,
the markets where the Properties are located, indicate an excellent potential
for continued high occupancy and  rental rate growth in 1998 and beyond.  These
three markets are projected to be among the top four U.S. markets in total
employment growth over the period 1993 to 2005, an average increase in each
market of over 50,000 or more jobs per annum, according to 1996 projections
prepared by the U.S. Dept. of Commerce, Bureau of Economic Analysis as indicated
on the following table:

     In the Washington, D.C. metropolitan area, employment and population growth
in recent years, and expected in future years, has been considerably stronger in
the northern Virginia

segment of the metropolitan area, which is the sector where the majority (69%)
of the Multifamily Properties are located. The growth in northern Virginia is
substantially attributable to continuing strong growth in the technology sector,
particularly the information technology and telecommunications segments. The
Operating Partnership believes that this trend will continue due to the
concentration of technology firms in northern Virginia and the growth outlook
for the information technology and telecommunications industries.

     Demand for multifamily rental apartments continues to be strong in the
Boston, Chicago and Washington, D.C. metropolitan areas as evidenced by high
occupancy and rent growth rates. Surveys of comparable investment grade
apartment properties are conducted in each of these markets annually by The REIS
Reports, Inc.  The results of these surveys are shown in the following tables:

MORTGAGE FINANCING

     As of  December 31, 1997, thirty-five of the 50 Properties were subject to
Mortgage Loans aggregating approximately $500,435,000. The Mortgage Loans are
collateralized by nonrecourse first lien mortgages or deeds of trust on
Properties organized into four pools ("Mortgage Pool One," "Mortgage Pool Two,"
"Mortgage Pool Three," and "Mortgage Pool Four", as shown in the chart below)
and seven individual loans (the "Acquisition Mortgages"). The Mortgage Loans
bear interest at a weighted average interest rate of  7.86% at December 31,
1997. The Properties collateralizing each Mortgage Loan, the outstanding
principal balances as of December 31, 1997, the applicable interest rates, and
the maturity dates for each Mortgage Loan are set forth in the chart below.

     Each of the related loan agreements for Mortgage Pool One and Mortgage Pool
Two requires the payment of interest only and contains cross-collateral and
cross-default provisions among the separate financing partnership borrowers in
each pool.  Prepayment of these loans would be subject to a yield maintenance
premium. The loan secured by Mortgage Pool Three is interest only through June
30, 1999, at which time amortization begins using a 25-year amortization
schedule with a balloon payment at maturity. In addition, this loan may not be
prepaid until May 1, 1999, at which time it would be subject to a yield
maintenance premium. The loan is cross-collateralized with the $83 million line
of credit from the same lender, as described below.  Certain predecessor
partners executed guarantees for $42 million of the mortgage loans secured by
Mortgage Pool Three.  The loan secured by Mortgage Pool Four was refinanced in
September 1996 and was obtained jointly with a ground lessor, with a portion of
the principal allocated to each of them.  The ground lessor has been allocated
$9.9 million of the refinanced loan (of the total of $41.0  million outstanding
as of December 31, 1997), for which the Operating Partnership is contingently
liable.  The loan requires the payment of interest only through August 2004, at
which time amortization begins using a 30-year amortization schedule with a
balloon payment due in August 2009.  The Operating Partnership remits full debt
service to the lender and reduces its ground rent payment by the corresponding
amount of debt service relating to the principal assigned to the ground lessor.

     The Acquisition Mortgages relate to the debt assumed on seven acquired
Multifamily Properties.  The loans  require monthly payments of interest and, in
certain cases, principal (1841 Columbia Road, Crystal Towers and Kenmore).


Lines of Credit

     The Operating Partnership had a $100 million revolving line of credit with
PNC Bank, Nations Bank and U.S. Bank (formerly First Bank), of which $75 million
was outstanding at December 31, 1997. Amounts outstanding bear interest at a
selected LIBOR rate plus 97.5 to 125 basis points (6.98% at December 31, 1997)
based on the leverage ratio of the related collateral. The Operating Partnership
paid an annual fee of .125% on the full amount of the line.  Borrowings under
this line of credit were collateralized by the Albemarle, Worldgate Centre,
Manor, Potomac View, Suburban Tower, Boulevard of Old Town I and II, and Van
Ness South apartments properties.

     In February 1998, the Operating Partnership established a  new $250
million, unsecured line of credit with PNC Bank, Nations Bank and U.S. Bank
which matures in March 2001.  Draws upon 

                                       21

the line are subject to certain unencumbered asset requirements. The Operating
Partnership repaid the balance outstanding under the existing $100 million line
and recognized an extraordinary loss of $0.3 million related to the
extinguishment of such debt. Borrowings under the new line bear interest at a
selected LIBOR rate plus 75 to 110 basis points based on the leverage ratio of
the Operating Partnership.

     The Operating Partnership also has a secured $83 million credit facility
with Northwestern Mutual Life expiring in June, 2004, to be used for property
acquisitions. The line provides for an interest rate that is fixed at the time
of each acquisition at a spread of 1.50% over 10-year Treasury Bills at that
time. Any properties acquired in this fashion will secure the facility, and it
is cross-collateralized with Mortgage Pool Three.  The balance of $30 million
outstanding at December 31, 1997 is collateralized by the Oakwood and Charter
Oak properties.  The blended interest rate  is 7.27%.

     Subsequent to the issuance of the Series C Preferred Units in the first
quarter of 1998, the related debt repayment and the newly established $250
million line of credit, the Operating Partnership had approximately $183 million
of unused borrowing capacity available on its lines of credit, subject to
unencumbered asset requirements.

     In October 1997, the Operating Partnership obtained a variable rate,
unsecured construction loan of $46.3 million to finance the construction of the
564-unit Courthouse Place property.  The loan is recourse to the Operating
Partnership, bears interest at LIBOR plus 130 basis point (6.93% at December 31,
1997), and matures in October 2000.  The loan balance at December 31, 1997 was
$5,536,000.


ITEM 3.   LEGAL PROCEEDINGS.

     The Operating Partnership  and/or the Property Service Businesses are
presently subject to legal actions or claims for damages that arise in the
ordinary course of business.  In the opinion of management and counsel to the
Operating Partnership, the ultimate outcome of such litigation will not have a
material adverse effect on the Operating Partnership's financial  position,
results of operations or cash flows.


ITEM 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

ITEM 5.   MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED SHAREHOLDER
          MATTERS.

     There is no established public trading market for the Units of the
Operating Partnership.  The Company's shares of Common Stock have been listed on
the New York Stock Exchange ("NYSE") since June 24, 1994, trading under the
symbol "SRW." Prior to that date, the Company's shares of Common Stock were not
publicly traded.

     During the fourth quarter of 1997, the Operating Partnership issued Units 
(as set forth in the chart below) for the purpose of acquiring all or part of an
ownership interest in a real estate property. The recipients of these Units have
been the partners of partnerships owning such property, who have swapped their
ownership interest for Units, cash, the assumption of debt, or some combination
thereof. These Units are offered on a private placement basis, and the offerings
are completed without an underwriter or the payment of sales commissions or
discounts. The Operating Partnership believes that such offerings and sales were
exempt from registration under the Securities Act of 1933, as amended (the
"Securities Act") by virtue of Section 4(2) of the Securities Act as the
securities were issued to accredited investors or affiliates in transactions not
involving a public offering.

     On October 3, 1997,  the Company issued 1,450,000 shares of Common Stock
and 1,216,666 shares of Series B Cumulative Convertible Redeemable Preferred
Stock ("Series B Preferred Shares") , $0.01 par value, liquidation preference of
$28.50 per share, for a total of $76 million.  The Company contributed the net
proceeds to the Operating Partnership in exchange for 1,450,000 common units and
1,216,666 Series B Preferred Units.

                                       24
<PAGE>
     The Operating Partnership amended the First Amended and Restated Limited 
Partnership Agreement of the Operating Partnership to designate and establish
the rights and privileges of the Series B Preferred Units which include certain
voting, distribution and liquidation preferences over the common unitholders,
mirroring the rights of the Preferred Shareholders.

     Distributions on the Series B Preferred Units are cumulative and are
payable quarterly at the greater of an annual rate of $2.02 per unit or the rate
declared on the common units. No distributions will be declared or paid on any
class of common or other junior units to the extent that distributions on Series
B Preferred Units have not been declared and/or paid. The Operating Partnership,
at its option, may redeem the Series B Preferred Units for Common Unit. The
investor may convert the Series B Preferred Shares into Common Shares on a one-
for-one basis subject to certain adjustments and limitations related to its
ownership of Common Units.

     On December 2, 1997, the Company sold an additional 923,191 Series A 
Preferred Shares for $24.7 million, net of $0.3 million in offering costs. The 
net proceeds were contributed to the Operating Partnership in exchange for 
923,191 Series A Preferred Units.

     In January 1998, the Company sold 500 shares of Series C Cumulative
Redeemable Preferred Stock ("Series C Preferred Shares"), $0.01 par value,  for
$48.9 million, net of offering costs of $1.1 million.  The net proceeds were
contributed to the Operating Partnership in exchange for 500 Series C
Preferred Units.  The Operating Partnership amended the First Amended and 
Restated Limited Partnership Agreement of the Operating Partnership to 
designate and establish the rights and privileges of the Series C Preferred 
Unitholders which include certain voting, distribution and liquidation
preferences over the common unitholders, mirroring the rights of the Preferred
Shareholders. The Series C Preferred Units have a liquidation preference of
$100,000 per unit and an initial annual distribution rate of $7,910 per unit. If
the securities receive an investment grade rating, the distribution will
decrease by $250 per unit. Distributions are cumulative and are payable
quarterly. The Operating Partnership may redeem Series C Preferred Units after
February 1, 2028, at the liquidation price plus accrued distributions.

     The Operating Partnership believes that such offering and sale was exempt 
from registration under the Securities Act  by virtue of Section 4(2) of the
Securities Act as the securities were issued to an affiliate in a transaction 
not involving a public offering.

     The following table sets forth the distributions made by the Operating
Partnership with respect to each such period:

1.   Includes revenues from the retail properties of  $10,645 in 1997, $10,176
     in 1996, $10,418 in 1995, $8,990 in 1994 and $8,048 in 1993.

2.   Funds from Operations (FFO) is defined by the National Association of Real
     Estate Investment Trusts (NAREIT) as  net income (loss) (computed in
     accordance with generally accepted accounting principles) excluding gains
     (or losses) from debt restructuring, and distributions in excess of
     earnings allocated to Minority Interest, plus depreciation/amortization of
     assets unique to the real estate industry. Depreciation/amortization of
     assets not unique to the industry, such as amortization of deferred
     financing costs and non-real estate assets, is not added back. FFO does not
     represent cash flow from operating activities in accordance with generally
     accepted accounting principles (which, unlike Funds from Operations,
     generally reflects all cash effects of transactions and other events in the
     determination of net income) and should not be considered an alternative to
     net income as an indication of the Operating Partnership's performance or
     to cash flow as a measure of liquidity or ability to make distributions.
     The Operating Partnership considers FFO a meaningful, additional measure of
     operating performance because it primarily excludes the assumption that the
     value of real estate assets diminishes predictably over time, and because
     industry analysts have accepted it as a performance measure. Comparison of
     the Operating Partnership's presentation of FFO, using the NAREIT
     definition, to similarly titled measures for other REITs may not
     necessarily be meaningful due to possible differences in the application of
     the NAREIT definition used by such REITs.

3.   Average occupancy is defined as gross potential rent for the core portfolio
     less vacancy allowance divided by gross potential rent for the period,
     expressed as percentage.

4.   At the formation of the Operating Partnership, all rental properties were
     recorded at predecessor partners' historical cost basis which is
     significantly less than current value and, therefore,  results in dilution
     of  partners' book value. Partners' equity as of December 31, 1997, 1996,
     1995 and 1994 is net of $(244,208) contribution by Predecessors of assets
     at historical cost, net of  liabilities.

5.   Represents mortgage loans, lines of credit and construction loans.

6.   Limited partnership units of the Other Limited Partners may be redeemed
     at the unitholder's discretion. Consequently, the Other Limited Partners'
     Interest, measured at redemption value, is not included in partner's
     equity. Partner's equity has been adjusted to reflect the redemption value
     of Other Limited Partners' Interest. (See footnote 15 to the financial
     statements.)

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS.


BACKGROUND

     The following discussion compares historical results of operations for the
years ended December 31, 1997 and 1996 as well as the years ended December 31,
1996 and 1995.  The discussion should be read in conjunction with the "Selected
Financial Data," and the financial statements and notes thereto included
elsewhere in this annual report.

THE OPERATING PARTNERSHIP

     The Operating Partnership is engaged primarily in the acquisition,
development, management and operation of multifamily properties. Together with
its subsidiaries, the Operating Partnership is a fully integrated real estate
organization with in-house acquisition, development, financing, marketing,
leasing and property management expertise.

     On June 30, 1994, Charles E. Smith Residential Realty, Inc. (the "Company")
made a $201.4 million capital contribution to the Operating Partnership for a 1%
general partnership interest and a 41.7% limited partnership interest in the
Operating Partnership.  The Company is the sole general partner of the Operating
Partnership.

     As of December 31, 1997, the Operating Partnership and its subsidiaries,
owned 45 operating multifamily properties, three multifamily properties under
construction and two retail shopping centers (collectively, the "Properties").
Two of the properties are located in Chicago, Illinois and one is located in
Boston, Massachusetts; all other properties are located in the Washington, D.C.
metropolitan area. The operating multifamily properties consist of the
following:

OCCUPANCY RATES

  Average occupancy of the Operating Partnership's core multifamily properties
compares favorably with the Washington, D.C. metropolitan area market-wide
average occupancy, based on annual surveys of approximately 80% of comparable
investment grade apartment properties conducted by The REIS Reports, Inc. as
follows:

<TABLE>

                              Occupancy Percent

                ---------------------   ------------------
       <S>             <C>                     <C>
        1997           96.4%                   96.4%
        1996           97.0%                   96.5%
        1995           97.2%                   95.9%
 
</TABLE>

  The decreases in occupancy in 1997 and 1996 are consistent with the Operating
Partnership's aggressive efforts to maximize apartment rents including various
revenue initiatives such as non-refundable move-in fees.  Also, it is important
to note that market data from The REIS Reports, 

                                       30
<PAGE>
 
Inc. is determined on a physical occupancy basis, whereas the Operating
Partnership's occupancy data is calculated on an economic basis. Physical
occupancy data commonly yields a slightly higher percentage than economic
occupancy because apartment units are considered physically rented when a rental
applicant's deposit is received, a point in time generally prior to the actual
rent commencement date used in computing economic occupancy.

RENTAL REVENUE

  Average revenue per apartment unit for the Operating Partnership's core
multifamily  properties increased approximately 3.5% in 1997 as compared with
1996, and 3.4% in 1996 (based on properties owned as of December 31, 1994) as
compared with 1995.

  Multifamily and Retail Property Management Services provide management
services to the Operating Partnership at cost plus 5% in accordance with the
management agreement. In addition to 46 owned Properties (Multifamily and
Retail), management services were also provided to 14 third-party owned
multifamily properties of approximately 3,800 apartment units and to three
third-party owned retail properties of approximately 293,000 square feet. Of the
17 third-party management agreements, twelve are with Affiliates and five are
with unaffiliated property owners. Two of the multifamily management agreements
were terminated in January 1998 when the Operating Partnership acquired the
properties. The management agreements with Affiliates are for initial terms of
three years or more while the management agreements with unaffiliated owners
generally have one-year terms. The average term for which the Operating
Partnership and its Predecessors have managed these properties is 20 years.

  Interior Construction and Renovation Services provided oversight to
approximately $66 million of gross construction activity in 1997 compared to
approximately $58 million in 1996 and $45 million in 1995. Services are provided
to the Operating Partnership at cost and to Affiliates and third parties at cost
plus a fee.

  Engineering and Technical Services provides on-site building systems
operations, maintenance and inspection to the Operating Partnership and
Affiliates at cost and to third parties at cost plus a fee. Services were
provided to approximately 30 million square feet of facilities in 1997 and 28
million square feet in 1996 and 1995.

  Financing Services performed $489 million of refinancings in 1997 compared to
$242 million in 1996 and $261 million in 1995.


RESULTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 31, 1997

COMPARISON TO YEAR ENDED DECEMBER 31, 1996

  SUMMARY.  Net income of the Operating Partnership increased 50.0%, or $17.4
million, from $34.8 million for the year ended December 31, 1996 to $52.2
million for the year ended December 31, 1997.  Funds from Operations ("FFO") of
the Operating Partnership increased $20.2 million, or 38.3%  during the same
period.  The increase in both net income and FFO is due to increases in income
from the rental properties, primarily the multifamily acquisition and
development properties.  These increases were partially offset by higher
interest and other expenses related to acquisitions and development.

  RENTAL PROPERTIES.  Revenue from rental properties increased $36.1 million, or
22.0%, from $164.0 million for 1996 to $200.1 million for 1997. The nine
multifamily acquisition properties, consisting of 4,038 apartment units,
contributed $30.4 million, or 84.2% of the rental revenue increase. This growth
was primarily due to the fact that six of the nine properties, or 3,036 units,
were acquired during 1997.  The core portfolio contributed an increase of $5.2

                                       34

million, or 3.5%, over 1996 while revenue from the retail properties increased
$0.5 million over 1996.

  Average monthly revenue per apartment unit of the core portfolio increased
from $870 in 1996  to $901 per month during 1997. Average economic occupancy
decreased to 96.4% in 1997 from 96.9% in 1996.  The decrease in occupancy was
not unexpected given continued efforts by management in 1997 to lead the market
in terms of rent increases as well as further growth of revenue-enhancing
initiatives such as the premium for month-to-month leases and the charging of a
non-refundable move-in fee in lieu of security deposits. The Operating
Partnership also continues to expand and aggressively market its furnished
apartment program. As a result, revenues from this program increased $0.5
million, or 34.9%, over the prior year period.

  Retail revenues increased by $0.5 million, or 4.6%, during 1997 compared to
the prior year due primarily to rent increases and improved vacancy at Skyline
Mall.  Average occupancy at Skyline Mall increased from 95.1% in 1996 to 97.2%
in 1997.  In addition, 1997 reflects a full year of retail revenue related to a
1996 multifamily property acquisition which also contained retail space.

  In December 1997, Messrs. Smith and Kogod sold their health club facilities
which lease retail space from the Operating Partnership.  In conjunction with
that sale, the Operating Partnership agreed to restructure the leases by
reducing base rent on the Worldgate lease and extending the terms on both leases
by ten years, through 2025, in exchange for a $2.3 million cash payment which
will be amortized over the lives of the revised leases. The Operating
Partnership used the funds to retire 65,000 Operating Partnership units.

  Expenses from rental properties (including depreciation) increased $15.3
million, or 17.2%, from $89.2 million in 1996 to $104.5 million in 1997.  The
increases resulted primarily from the acquisition of 4,038 apartment units
subsequent to December 31, 1995 which added $12.3 million in property operating
expenses compared to the prior year.  The increase of $2.7 million in
depreciation expense for 1997 is primarily due to the impact of 1996 and 1997
acquisitions.  The increase of $0.3 million, or 0.4%, in property operating
expenses for the core portfolio was primarily due to expected increases in
payroll and related costs, partially offset by savings from management
restructuring and the outsourcing of janitorial services.

  Operating margins of the Operating Partnership's core portfolio of
approximately 57% and 56% for the years ended December 31, 1997 and 1996,
respectively, are generally lower in comparison to industry averages due
primarily to its method of recovering utility costs.  The Operating
Partnership's apartment rents, for the most part, include utility services such
as electricity and gas since the Operating Partnership bears utility costs. The
majority of the Operating Partnership's competitors, however, require their
tenants to pay utilities directly. Management estimates that the Operating
Partnership's operating margins would be approximately 60% on a comparable
basis.

  PROPERTY SERVICE BUSINESSES.  Income from the Property Service Businesses
decreased $0.2 million, or 3.2%, during 1997 compared to 1996.

  Income before depreciation for Multifamily and Retail Property Management
Services decreased $1.5 million, or 65.6%, primarily due to a non-recurring fee
of $0.6 million earned in 1996 in connection with the termination of a
management agreement with a hotel owned by a related party.  In addition,
revenue decreased by an additional $0.9 million due to the February 1997
acquisition of two properties previously managed by the Operating Partnership's.

  Income before depreciation for Interior Construction and Renovation Services
increased $0.1 million, or 8.9%, due to an increase of $1.0 million in net fee
revenue offset by an increase of $0.9 million in related expenses.

  Revenue from Engineering and Technical Services increased 20.0%, or $8.4
million, in 1997 with a corresponding increase of $8.2 million in expenses
compared to 1996 due primarily to additional HVAC systems operations and
preventative maintenance contracts obtained throughout 1997.  Due to start-up
costs on the new contracts, operating margins during 1997 were lower than 1996.
Consequently, income before depreciation for Engineering and Technical Services
increased a moderate 4.8% to $3.8 million for 1997 compared to $3.7 million in
1996.

  Income before depreciation for Financing Services increased $1.2 million, or
60.2%,  due primarily to fees earned on an unusually high level of refinancings
performed during the fourth quarter of 1997.  Such refinancings were related to
the roll-up of Affiliated commercial properties into a single partnership.  In
conjunction with the roll-up, Financing Services personnel transferred to the
new entity, Charles E. Smith Commercial Realty L.P.("CESCR").  The Operating
Partnership entered into agreements through December 31, 1998 to provide
Financing Services for certain properties owned and certain properties to be
acquired by CESCR.  Services will be provided utilizing CESCR personnel on a
negotiated cost basis.  The Operating Partnership will separately negotiate
revenue and cost sharing agreements for Financing Services it may provide, if
any, to properties managed but not owned by CESCR.

  OTHER.  Corporate general and administrative expenses increased by $1.3
million, or 24.9%, due primarily to additional personnel added during the year
to expand  the Operating Partnership's acquisition and development program
outside of the Washington, D.C. metropolitan area to other U.S. cities with
strong urban multifamily markets.  Interest expense increased by $1.8 million,
or 4.1%, primarily due to assumed debt on acquisitions of multifamily
properties.

RESULTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 31, 1996

COMPARISON TO YEAR ENDED DECEMBER 31, 1995

  SUMMARY. Net income of the Operating Partnership increased 12.1%, or $3.8
million, from $31.1 million for the year ended December 31, 1995 to $34.8
million for the year ended 

                                       36
<PAGE>
 
December 31, 1996. Funds from Operations of the Operating Partnership increased
$5.4 million, or 11.5%, during the same period. The increase in both net income
and FFO is due to increases in income from the rental properties, primarily the
multifamily acquisition and development properties, as well as increased income
from the Property Service Businesses. These increases were partially offset by
an increase in interest expense related to multifamily acquisitions and
development.

  RENTAL PROPERTIES.  Revenue from rental properties increased $20.5 million, or
14.3%, from $143.5 million for 1995 to $164.0 million for 1996. The three
multifamily acquisition properties, consisting of 1,002 apartment units (note
that five properties purchased and one property constructed in 1995 totaling
1,736 apartment units were transferred into the core portfolio on January 1,
1997), contributed $5.6 million of the rental revenue increase. The core
portfolio contributed an increase of $15.2 million over 1995 (which includes
$10.8 million impact of transferring the six properties to core on January 1,
1997), offset by a $0.2 million decrease in revenue from the retail properties.

  Average monthly revenue per apartment unit of the core portfolio (based on
properties owned as of December 31, 1994) increased 3.4% from $854 in 1995 to
$883 per month during 1996. Average economic occupancy decreased slightly to
97.0% in 1996 from 97.2% in 1995. The decrease in occupancy was not unexpected
given the aggressive efforts initiated by management to increase rents as well
as the implementation during the third quarter of 1996 of several revenue-
enhancing initiatives, including a premium for month-to-month leases and the
charging of a non-refundable move-in fee in lieu of security deposits.

  Retail revenues decreased by $0.2 million, or 2.3%, during the year ended
December 31, 1996 compared to the prior year due to lower base and percentage
rents as well as higher vacancy at Skyline Mall. Average occupancy at Skyline
Mall declined from 97.3% in 1995 to 95.1% in 1996 due to several stores
remaining vacant during the last six months of 1996. In addition, repairs and
maintenance expenses were higher in 1996 than in 1995.

  Expenses from rental properties (including depreciation) increased $10.7
million, or 13.6%, from $78.5 million in 1995 to $89.2 million in 1996. The
increases resulted primarily from the acquisition/development of 2,738 apartment
units subsequent to December 31, 1994 which added $9.0 million in property
operating expenses compared to the prior year. The increase of $6.3 million in
operating expenses for the core portfolio (which includes $3.6 million impact of
transferring the six properties to core on January 1, 1997) was primarily due to
expected increases in payroll and related costs, increased repairs and
maintenance costs and increased snow removal costs caused by the record snowfall
in the first quarter of 1996. In addition, real estate taxes were significantly
higher in 1996 primarily in the Virginia submarkets which constitute the
majority of the portfolio. Assessments averaged 5.5% higher in 1996 than in 1995
for the Virginia properties while local property tax rates for Arlington and
Fairfax counties increased by 2.1% and 5.9%, respectively. The substantial
increase in utility costs during the first quarter of 1996 was mostly offset in
the third quarter by an unseasonably cool summer.

  PROPERTY SERVICE BUSINESSES. Income from the Property Service Businesses
increased $1.0 million, or 14.2%, during 1996 compared to 1995.

  Income before depreciation for Multifamily and Retail Property Management
Services increased $0.3 million, or 14.3%, resulting primarily from the impact
of a non-recurring fee of $0.6 million related to the termination of a
management agreement with a hotel owned by a related party. The hotel was sold
during the first quarter of 1996. In addition, retail leasing income increased
by approximately $0.2 million due primarily to retail leases for a third party
development project. These increases were offset by approximately $0.5 million
of increased marketing expenditures for furnished corporate apartments, Smith
Advantage, and other tenant services. Also, although income from residential
management services increased approximately $0.2 million due to the growth in
the size of the portfolio, the increase was offset by the cost of severance and
other benefits related to a late 1996 management reorganization in this group.

  Income before depreciation for Interior Construction and Renovation Services
decreased $0.1 million, or 11.4%, due primarily to a 4.3% decrease in net fee
revenue caused by a shift to lower margin, third-party construction management
services compared to higher margin general contracting services provided to
Affiliates.  The decrease in revenues was partially offset by a 2.6% decrease in
operating expenses resulting primarily from worker's compensation insurance
savings due to favorable claims experience.

  Revenue from Engineering and Technical Services increased 5.0%, or $2.0
million, in 1996 to $42.2 million compared to 1995 due primarily to additional
HVAC systems operations and preventative maintenance contracts obtained in late
1995 and throughout 1996. As a result of the growth in revenue, expenses
increased by $1.8 million, or 4.9%, due primarily to additional payroll and
related benefit costs associated with performing the additional work as well as
increased information technology costs. Consequently, income before depreciation
for Engineering and Technical Services increased 5.1% to $3.7 million for 1996
compared to $3.5 million in 1995.

  Income before depreciation for Financing Services increased $0.4 million, or
23.7%,due primarily to savings in payroll and related expenses during the latter
half of 1996. These savings were partially offset by reduced revenue associated
with the $19 million decrease in refinancings performed in 1996 compared to
1995.

     OTHER. Corporate general and administrative expenses increased by $0.5
million, or 10.2%, due primarily to costs incurred in connection with the
Operating Partnership's acquisition and development efforts including write-offs
of capitalized costs for terminated acquisition efforts. Interest expense
increased by $6.2 million, or 16.5%, due to the assumption of debt and
additional borrowings under the lines of credit related to the acquisition and
development of multifamily properties.

LIQUIDITY AND CAPITAL RESOURCES

SUMMARY

  Net cash flow provided by operating activities was $75.2 million for 1997
compared to $51.0 million for 1996. The increase of $24.2 million was primarily
due to higher cash flow contributed by the acquisition portfolio as well as core
revenue growth.  Although the acquisition portfolio also increased accounts
payable, the cash flows were offset by related increases in receivables.

  Net cash flow used by the Operating Partnership for investing activities
increased $124.2 million in 1997, from $72.7 million in 1996 to $196.9 million
in 1997 due to the substantial increase in acquisition volume during the year as
well as increased capital expenditures.

  Net cash flow provided by financing activities was $117.8 million in 1997
compared to $16.2 million in 1996.  The Operating Partnership significantly
deleveraged in 1997 through issuance of equity in order to finance increased
acquisition and development activities. Approximately $203 million was raised in
1997 through sales of common and preferred equity with net repayments of debt of
approximately $29 million. In 1997, the Operating Partnership paid distributions
of $53.5 million, or $2.035 per unit representing three quarters of
distributions at $.505 per unit and one quarter at $.52, a 3.0% increase.

EQUITY ACTIVITY

  During the first quarter of 1997, the Company issued 3.1 million shares of
common stock in an equity offering at $28.375 per share resulting in proceeds of
$82.9 million, net of underwriting discounts and other expenses totaling $5.2
million.  The Company used the net proceeds from the offering to purchase 3.1
million limited partnership units of the Operating Partnership.  The Operating
Partnership used the resulting proceeds to repay $72.1 million on the line of
credit and $9.0 million of mortgage debt and to fund three property
acquisitions.

  In May 1997, the Company entered into an agreement with a private investor to
sell 2.6 million shares of Series A Cumulative Convertible Redeemable Preferred
Stock ("Series A Preferred Shares") for $71.5 million no later than May 14,
1998.  On June 30, 1997, the Company issued 0.7 million shares of Series A
Preferred Shares at $27.08 per share resulting in proceeds of $19.8 million, net
of underwriting discounts and other expenses totaling $0.2 million. In December
1997, the Company issued 0.9 million shares of Series A Preferred Shares at
$27.08 per share resulting in proceeds of $24.7 million, net of expenses of $0.3
million.  The net proceeds of both issuances were contributed to the Operating
Partnership in exchange for 1.6 million Series A Preferred Units.  The Operating
Partnership used the proceeds to repay a portion of the  line of credit.

                                       39
<PAGE>
 
  In October 1997, the Company sold 1.45 million shares of common stock and 1.22
million shares of Series B Cumulative Convertible Redeemable Preferred Stock
("Series B Preferred Shares") to a private investor for $76 million.  The net
proceeds were contributed to the Operating Partnership in exchange for 1.45
million common units and 1.22 million Series B Preferred Units. The Operating
Partnership used the proceeds to fund an acquisition.

  During 1997, the Operating Partnership issued approximately 2.1 million
Operating Partnership units valued at $61.1 million in connection with property
acquisitions.

  In January 1998, the Company sold 500 shares of Series C Cumulative Redeemable
Preferred Stock ("Series C Preferred Shares") for $48.9 million, net of offering
costs of $1.1 million.  The Company contributed the net proceeds to the
Operating Partnership in exchange for 500 shares of Series C Preferred Units.
The Series C Preferred Units have a liquidation preference of $100,000 per unit
and an initial annual distribution rate of $7,910 per unit.  If the securities
receive an investment grade rating, the distribution rate will decrease by $250
per unit. The Operating Partnership used the proceeds to repay outstanding
amounts under its lines of credit.

FUNDS FROM OPERATIONS

  FFO is defined by the National Association of Real Estate Investment Trusts
("NAREIT") as net income (loss) (computed in accordance with generally accepted
accounting principles) excluding gains (or losses) from debt restructuring, and
distributions in excess of earnings allocated to Minority Interest, plus
depreciation/amortization of assets unique to the real estate industry.
Depreciation/amortization of assets not unique to the industry, such as
amortization of deferred financing costs and non-real estate assets, is not
added back. FFO does not represent cash flow from operating activities in
accordance with generally accepted accounting principles (which, unlike FFO,
generally reflects all cash effects of transactions and other events in the
determination of net income) and should not be considered an alternative to net
income as an indication of the Operating Partnership's performance or to cash
flow as a measure of liquidity or ability to make distributions. The Operating
Partnership considers FFO a meaningful, additional measure of operating
performance because it primarily excludes the assumption that the value of real
estate assets diminishes predictably over time, and because industry analysts
have accepted it as a performance measure. Comparison of the Operating
Partnership's presentation of FFO, using the NAREIT definition,  to similarly
titled measures for other REITs may not necessarily be meaningful due to
possible differences in the application of the NAREIT definition used by such
REITs.

  The Operating Partnership's FFO for the years ended December 31, 1997, 1996
and 1995 was as follows (in thousands):

  In January 1998, the Operating Partnership completed the acquisition of two
multifamily properties in northwest Washington, D.C. totaling 287 apartment
units.  The total cost of approximately $12.1 million was comprised of $3.3
million cash and 254,000 Operating Partnership units valued at approximately
$8.8 million.  The Operating Partnership previously owned a 20% interest in one
of the properties, and both properties were previously managed by the Operating
Partnership.  The Operating Partnership also finalized a contract to purchase in
the second quarter of 1998 a 299-unit multifamily property located in the
Crystal City submarket of Arlington, Virginia.  The purchase price of $39
million is expected to be funded from the line of credit.

DEVELOPMENT

  Springfield Station.  The Operating Partnership purchased for $9.1 million
approximately 17 acres of land and is nearing completion on the first phase of
construction of an estimated 630-unit mid-rise and garden apartment property in
Springfield, Virginia.  The site is located adjacent to a new Metrorail and
commuter rail station and a regional shopping mall and offers convenient access
to major transportation routes.  Total cost is expected to be approximately $60
million with final delivery in mid-1999.

  Courthouse Place.  On October 8, 1997, the Operating Partnership acquired a
564-unit, luxury high rise property under construction in Arlington, Virginia
for $17.5 million consisting of $3.6 million cash and approximately 450,000
Operating Partnership units valued at $13.9 million.  Total expected project
cost is approximately $65 million.  The balance of construction cost will be
funded through a construction loan secured in October 1997 at LIBOR plus 130
basis points which matures in October 2000. The balance outstanding at December
31, 1997 is $5.5 million.  Management expects to initially deliver apartment
units in October 1998, with completion in the fall of 1999.

  One Superior Place.  During the fourth quarter of 1997, the Operating
Partnership began construction of a 52-story, 809-unit luxury high rise
apartment and commercial center in downtown Chicago.  The $112 million project,
which is expected to be funded through a construction loan, will also include a
new Whole Foods supermarket and other tenants in its 52,000 square feet of
commercial space. Management expects to initially deliver units in September
1999 with completion in mid-2000.

  Numerous other acquisition and development projects are being pursued by the
Operating Partnership.  The Operating Partnership anticipates meeting the
related funding requirements through draws on its lines of credit, long-term
borrowings and public or private issuances of equity, including Operating
Partnership unit exchanges.

DEBT

  As of December 31, 1997, the Operating Partnership had the following mortgage
indebtedness and other borrowings carrying a weighted average interest rate of
7.71% and collateralized by 44 of the 50 Properties:

versus 45.9% at December 31, 1996. The decreases are attributable to the 1997
common and preferred equity sales, acquisitions funded via Operating Partnership
unit exchanges, and an increasing stock price of the Company. The Operating
Partnership's Interest Coverage Ratios for the years ended December 31, 1997 and
1996 were 2.78:1 and 2.38:1, respectively.

securities or public or private equity offerings.

    In February 1998, the Operating Partnership terminated its existing $100
million line of credit and entered into a new $250 million, unsecured line of
credit with PNC Bank, Nations Bank, and U.S. Bank which matures in March 2001.
Draws upon the new line are subject to

certain unencumbered asset requirements and bear interest at a selected LIBOR
rate plus 75 to 110 basis points based on the leverage ratio of the Operating
Partnership. If the Operating Partnership receives an investment grade rating,
the interest rate will decrease to 60 to 90 basis points over LIBOR based on the
rating. The Operating Partnership repaid the balance outstanding under the $100
million line and recognized an extraordinary loss of $0.3 million related to the
extinguishment of such debt.

    CAPITAL IMPROVEMENTS.  In 1997, total capital improvements were $12.8
million, of which $10.3 million, or $727 per apartment unit, was for the core
portfolio.  Approximately 36% of the capital expenditures on the core portfolio
are considered by management to be revenue generating or economic improvements,
as shown below, which management believes directly affect the Operating
Partnership's ability to increase rents. The remaining capital expenditures on
the core portfolio indirectly influence the Operating Partnership's ability to
increase rents and are considered non-revenue generating.  A summary of core
capital expenditures during 1997 follows:

     INCOME TAXES. The Property Service Businesses are taxable corporations, and
thus, pay Federal and state income taxes on their net income. Such taxes
amounted to $ 0.4 million, $0.4 million and $0.6 million for 1997, 1996 and
1995.

     EFFECT OF INFLATION. Substantially all of the leases at the Multifamily
Properties are for a term of one year or less, which enables the Operating
Partnership to seek increased rents upon 

                                       44

renewal or reletting of apartments. Retail tenant leases provide for pass-
through of common area maintenance, real estate taxes and other operating costs
to tenants, which reduces the impact of inflation.

     YEAR 2000.  The Operating Partnership has conducted a comprehensive review
of its internal computer systems and related software to identify issues related
to year 2000 compliance. Accordingly, the Operating Partnership has determined
that it has no material risks related to the ability of its hardware and
software to recognize the year 2000 and beyond as valid dates. The Operating
Partnership's primary financial and operational software programs are purchased
from outside vendors who have generally resolved or are in the process of
resolving year 2000 issues. The Operating Partnership is in the process of
replacing one computer system, however, which is not currently year 2000
compliant at an estimated cost of approximately $1 million.  The new system will
be operational in early 1999 and the related cost will be depreciated over its
estimated useful life.  During 1998, the Operating Partnership will continue to
monitor year 2000 issues (primarily using internal staff) including analysis of
its secondary applications software and suppliers and review of its service
providers for year 2000 compliance. The Operating Partnership does not expect
any material adverse impact to its business operations from service providers'
inability, if any, to become year 2000 compliant.  Costs associated with the
Operating Partnership's ongoing year 2000 compliance review and any necessary
system or software modifications are expensed as incurred.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Unitholders of Charles E. Smith Residential Realty L.P.:


We have audited the accompanying consolidated balance sheets of Charles E. Smith
Residential Realty L.P. (a Delaware limited partnership) and subsidiaries as of
December 31, 1997 and 1996 and the related consolidated statements of
operations, partner's equity and other limited partners' interest, and cash
flows for the years ended December 31, 1997, 1996 and 1995. These consolidated
financial statements and the schedule referred to below are the responsibility
of the management of Charles E. Smith Residential Realty L.P. Our responsibility
is to express an opinion on these consolidated financial statements and schedule
based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Charles E. Smith
Residential Realty L.P. and subsidiaries as of December 31, 1997 and 1996, and
the consolidated results of its operations and its cash flows for the years
ended December 31, 1997, 1996 and 1995, in conformity with generally accepted
accounting principles.

Our audit was made for the purpose of forming an opinion on the basic financial
statements taken as a whole. The schedule listed in the index to financial
statements is presented for purposes of complying with the Securities and
Exchange Commission's rules and is not part of the basic financial statements.
This schedule has been subjected to the auditing procedures applied in the audit
of the basic financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

                   CHARLES E. SMITH RESIDENTIAL REALTY L.P.
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1. ORGANIZATION AND FORMATION OF COMPANY

     Charles E. Smith Residential Realty L.P. (The "Operating Partnership") was
organized in Delaware in 1993.  The Operating Partnership had no operations
prior to the completion of the business combination (discussed below) which
occurred on June 30, 1994.  Charles E. Smith Residential Realty, Inc. (the
"Company"), formed in June 1993, is a self-administered and self-managed equity
real estate investment trust ("REIT").  On June 30, 1994, the Company raised
equity through an initial public offering and a private placement (the
"Offerings"), and issued debt in a series of concurrent private financing
transactions. The proceeds from the Offerings were used to acquire the 1.0% sole
general partnership and a 41.7% limited partnership interest in the Operating
Partnership.

      Simultaneous with the Offerings, the entities that owned the properties
and the related service businesses included in the CES Group contributed the
properties (the "Predecessor Properties") and the management, development,
leasing, interior construction, engineering, and financing services business
segments of the Predecessor to the Operating Partnership (or corporations in
which the Operating Partnership owns substantially all of the equity) and
received in exchange, directly or indirectly, units of limited partnership in
the Operating Partnership. (The contributing entities and their owners, which
include Robert H. Smith and Robert P. Kogod and their families, and other former
owners of indirect interests in contributed properties, are referred to
collectively as the "Other Limited Partners"). The contributed assets and
liabilities were recorded at historical net book value which transferred a net
carry-over deficit of $244.2 million to the Operating Partnership.

     The Operating Partnership and its subsidiaries are engaged in the
ownership, operation, management, leasing, acquisition, and development of real
estate properties, primarily residential multifamily properties. As of December
31, 1997, the Operating Partnership owned 45 operating multifamily properties
containing 18,236 apartment units (the "Properties"), had approximately 2,000
units under construction at three additional sites and owned two free-standing
community retail shopping centers aggregating 436,000 square feet.  The
properties are located in the following metropolitan areas:

     Additionally, the Operating Partnership owned substantially all of the
equity in entities which provide multifamily and retail property management and
leasing, interior construction and renovation, building engineering and
technical services, and financial advisory services (collectively, the "Property
Service Businesses").


2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

     The accompanying consolidated financial statements include all of the
accounts of the Operating Partnership and its subsidiaries and affiliates.  The
Operating Partnership uses the equity method of accounting for its 99% non-
voting interest in the Property Service Businesses.

     All significant intercompany balances and transactions have been
eliminated.

RENTAL PROPERTY

  The Operating Partnership recorded the contributed Predecessor Properties at
the Predecessor's historical cost.  Rental property subsequently acquired or
developed is recorded at the Operating Partnership's actual cost, including
interest and real estate taxes incurred during development.  Ordinary repairs
and maintenance, such as minor replacements and painting, are expensed as
incurred; major improvements, such as new HVAC equipment and kitchen/bath
renovations, are capitalized when they extend the useful life, increase capacity
or improve the efficiency of the asset. Depreciation on buildings and
improvements is computed using the straight-line method over estimated useful
asset lives as follows:

          Base building           40 years
          Land improvements       20 years
          Building improvements   7 to 20 years
          Tenant improvements     Shorter of remaining lease term or useful life
          Furniture, fixtures 
           and equipment          5 to 10 years

                                      F-8
<PAGE>
 
DEFERRED CHARGES

    Deferred charges consist primarily of permanent loan fees, which are
amortized to interest expense over the terms of the notes using the effective
interest rate method, and retail lease acquisition costs, which are amortized
over the terms of the related leases.


REVENUE RECOGNITION

     Rental income attributable to residential leases is recognized when due
from tenants. The Operating Partnership requires residential tenants to
initially execute a one-year lease. At the expiration of the lease term, if not
renewed, the lease converts to a month-to-month basis.

     Minimum rental income attributable to retail leases is recognized on a
straight-line basis over the term of the lease regardless of when payments are
due. Minimum rental income recognized in excess of payments due was $5.0 million
and $6.8 million at December 31, 1997 and 1996, respectively, and is included in
other assets. The lease agreements contain provisions that provide for
additional rentals based on the tenants' sales volume and reimbursement from the
tenants for their share of real estate taxes and certain common area maintenance
costs. Additional rentals are recognized on the accrual basis.

     The future minimum lease payments to be received by the Operating
Partnership under noncancelable retail leases as of December 31, 1997, are as
follows (in thousands):

INCOME TAXES

     These financial statements contain no provision for Federal income taxes
since the entity is a partnership and, therefore, all Federal income tax
liabilities and/or tax benefits are passed through to the individual partners in
accordance with the partnership agreement and the Internal Revenue Code.

                                      F-9
<PAGE>
 
     The Operating Partnership's income tax basis in its assets and liabilities
was $702 million and $635 million, respectively, at December 31, 1997 and $470
million and $558 million, respectively, at December 31, 1996.
 
CASH AND CASH EQUIVALENTS

     Cash and cash equivalents include all cash and cash equivalent investments
with original maturities of three months or less.

USE OF ESTIMATES IN THE FINANCIAL STATEMENTS

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions related to the net realizable value of rental property, the
collectibility of accounts and notes receivable, and the outcome of asserted and
unasserted claims that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods.  Actual results could differ from those estimates.

IMPAIRMENT OF LONG-LIVED ASSETS

     Management assesses for impairment any property whenever events or
circumstances indicate that the carrying amount may not be recoverable. An
impairment loss is recognized when the sum of the estimated undiscounted future
cash flows before interest charges is less than its carrying value.  The loss is
measured as the difference between the carrying value and the fair value of the
property.

STOCK-BASED COMPENSATION

     The Company accounts for stock-based compensation programs under Accounting
Principles Board Opinion No. 25 whereby compensation expense is equal to the
excess, if any, of the quoted market price of the stock at the grant date over
the exercise price.

NEW ACCOUNTING PRONOUNCEMENTS

     During 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standard ("SFAS") No. 128, "Earnings Per
Share" which specifies the computation, presentation, and disclosure
requirements for earnings per share for entities with publicly held common stock
or potential common stock.  The standard is effective for interim and annual
periods ending after December 15, 1997 and requires restatement of comparative
prior-period data.  The Operating Partnership has adopted SFAS No. 128 and all
prior period amounts have been restated to conform with this standard.

                                      F-10
<PAGE>
 
     During 1997, the FASB also issued several additional standards including
SFAS No. 129, "Disclosure of Information About Capital Structure", SFAS No. 130,
"Reporting Comprehensive Income" and SFAS No. 131, "Disclosures About Segments
of an Enterprise and Related Information".  SFAS No. 129 is effective for
reporting periods ending after December 15, 1997 and had no impact on the
Operating Partnership's financial statements.   SFAS No. 130 and SFAS No. 131
are effective beginning in 1998 and are not expected to have any significant
impact on the Operating Partnership's financial statements.

RECLASSIFICATIONS

     The Operating Partnership changed the classification of certain senior
management payroll costs from property operating expenses to corporate general
and administrative expense. Management believes this reclassification more
accurately reflects property operations and is consistent with industry
practice.  Approximately $2.2 million and $1.9 million, respectively, for the
years ended December 31, 1996 and 1995 have been reclassified to conform to the
current year's presentation.

     Certain other reclassifications of the prior years' information have been
made to conform to the current year's presentation.

property for a total cost of approximately $23.9 million.


4.   INVESTMENT IN AND ADVANCES TO PROPERTY SERVICE BUSINESSES AND OTHER

     The Operating Partnership uses the equity method of accounting for its 99%
non-voting interest in the Property Service Businesses, which include Smith
Realty Company ("SRC"), Consolidated Engineering Services, Inc. ("CES") and
Smith Management Construction, Inc. ("SMC"). These companies provide services
which include property management, leasing, engineering and technical, financing
and property construction and renovation. Under the equity 

                                      F-12
<PAGE>
 
method, the Operating Partnership's investment is adjusted for its proportionate
share of earnings or losses of the Property Service Businesses and by dividends
received. The Operating Partnership recognized its 99% interest in the earnings
of each of the Property Service Businesses which aggregated $7.6 million, $7.8
million and $6.9 million for the years ended December 31, 1997, 1996 and 1995,
respectively. The Operating Partnership received distributions aggregating $8.9
million, $8.9 million and $8.2 million for the years ended December 31, 1997,
1996 and 1995, respectively.

     The Property Service Businesses provide services to the Operating
Partnership under one-year agreements which are automatically renewable. Such
services are generally provided at cost (including a proportionate share of
total overhead) except property management and leasing services which are
provided at cost plus five percent. The Property Service Businesses also provide
services to certain partnerships which own multifamily and commercial office
properties and have Messrs. Smith and Kogod as the general partners
("Affiliates"). Such services are generally provided at cost (including
overhead) plus a fee, except for certain engineering and technical services
which are provided at cost and overhead.

     In November 1997, certain Affiliates combined into a single partnership,
Charles E. Smith Commercial Realty L.P. ("CESCR").  In conjunction with the
combination, CES and SMC each entered into eight-year agreements with CESCR to
continue providing services under the same terms and conditions in place prior
to the business combination.  In addition, certain Financing Services personnel
of SRC transferred to CESCR.  SRC entered into agreements through December 31,
1998 to provide Financing Services for certain properties owned and certain
properties to be acquired by CESCR.  Services will be provided utilizing CESCR
personnel on a negotiated cost basis.  SRC will separately negotiate revenue and
cost sharing agreements for Financing Services it may provide, if any, to
properties managed but not owned by CESCR.

     In addition to the above, SRC provided administrative services such as
accounting, systems and human resources services to the Operating Partnership
and Affiliates at cost and overhead in accordance with cost and executive
sharing agreements. In management's opinion, the allocation methods provide
reasonable estimates of the costs that would have been incurred had the services
been provided by the Operating Partnership.

10.  RELATED-PARTY TRANSACTIONS

     The Operating Partnership conducts business with entities in which Messrs.
Smith and Kogod exercise control.  In each case, the Company's Board of
Directors reviews the transaction and obtains, as required, independent
assurance as to the arms-length nature of the terms.  The following is a
description of these transactions.

     In connection with the development of the Westerly at Worldgate apartments,
     the Operating Partnership purchased the land in 1994 for $4.7 million from
     an affiliate controlled by Messrs. Smith and Kogod. Also, a contract was
     executed with an entity controlled by Messrs. Smith and Kogod to manage the
     construction of the apartments at a fee of 4% of hard construction costs.
     Construction management fees were $0.5 million for the year ended December
     31, 1995 and $0.2 million for the period from June 30, 1994 to December 31,
     1994. The project was completed in December 1995.

     Partnership paid approximately $0.7 million, $0.7 million and $0.3 million,
     respectively,  in payroll reimbursements to an entity controlled by Messrs.
     Smith and Kogod for efforts on development properties and potential
     development sites.

     In February 1997, the Operating Partnership purchased two multifamily
     properties (Crystal Plaza and Crystal Towers) totaling $112.8 million from
     partnerships in which Messrs. Smith and Kogod had ownership interests. 

     In connection with the development of Springfield Station, a contract was
     executed with an entity controlled by Messrs. Smith and Kogod to manage the
     construction of the apartments at a fee of 4% of hard construction costs.

     1997, the health clubs were sold. In conjunction with that sale, the
     Operating Partnership agreed to restructure the leases by reducing base
     rent on the Worldgate lease and extending the terms of both leases for ten
     years, through 2025, in exchange for a $2.3 million cash payment which will
     be amortized over the lives of the revised leases. The Operating
     Partnership used the funds to retire 65,000 Operating Partnership units.


11.  FAIR VALUE OF FINANCIAL INSTRUMENTS

     Statement of Financial Accounting Standards No. 107 requires disclosure
about fair value for all financial instruments. Based on the borrowing rates
currently available to the Operating Partnership for mortgages with similar
terms and remaining maturities, the fair value of mortgages payable was
approximately $527 million and $427 million at December 31, 1997 and 1996,
respectively. The fair values of lines of credit and construction loans
approximate the carrying values.


12.  EARNINGS PER UNIT

     For the year ended December 31, 1997, basic and diluted earnings per common
unit is computed based on 26.7 million weighted average units outstanding during
the year and 26.8 million weighted average units outstanding during the year
adjusted for the assumed conversion of dilutive securities, respectively.  For
the years ended December 31, 1996 and 1995, weighted average units outstanding
were 21.9 million and 21.6 million, respectively, for both basic and diluted
earnings per common unit.  The per-unit impact in 1997 of the extraordinary
item was immaterial.

</TABLE>

     Options to purchase 798,500 shares of the Company's common stock at $35 
per share were not included in the computation of diluted earnings per unit
because the options' exercise price was higher than the average price of the
Company's common shares. All convertible preferred units were also excluded 
from the calculation of diluted earnings since the preferred dividends paid per
unit exceeded basic earnings per unit.


13.  INCENTIVE PLANS

     The Company applies Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees" and related interpretations in accounting for its
plans.  Accordingly, no compensation expense has been recognized for its stock-
based compensation plans other than for restricted stock and performance-based
awards.  Had compensation cost for the Company's other stock option plans been
determined based on the fair value at the grant date consistent with the
methodology prescribed under SFAS 123, the Operating Partnership's net income
would have been reduced by approximately $65,000 (less than $0.01 per basic and
diluted common unit) for the year ended December 31, 1997 and $8,000 for the
year ended December 31, 1996.  The fair value of options granted during 1997 and
1996 is estimated at approximately $2,111,000 and $23,000, respectively, based
on the date of grant using the Black-Scholes option-pricing model.  The
following assumptions were used for 1997 and 1996, respectively: dividend yield
of 6.8% and 8.3%, volatility of 14% and 9%, risk-free interest rate of 5.7% and
6.3% and an expected life of 3 years and 7 years.

OPTION PLANS

     The Company with the Operating Partnership maintains an employee stock 
and unit option plan designed for executive officers and other key employees of
the Company, the Operating Partnership and the Property Service Businesses.
Messrs. Smith and Kogod are not eligible to participate under this plan. The
Company also maintains a Director's stock option plan which provides for
automatic grants of vested options, exercisable for 5,000 shares of common
stock, to newly appointed non-employee directors. The plans authorize the
issuance of up to 1,750,000 shares of common stock and/or units pursuant to
options granted under these plans. Options outstanding under both plans are as
follows:

     The exercise price of options granted under the plans may not be less than
the fair market value of the common stock on the date of grant. Payment for
shares and/or units granted under the plans may be made either in cash, or, if
permitted by the option agreement, by exchanging shares of common stock of the
Company having a fair market value equal to the option exercise price. The
weighted average remaining contractual life of options outstanding as of
December 31, 1997 was 8.4 years.

     Options granted under the employee plan have a maximum term of ten years
and vest generally in three to five equal annual installments beginning on the
first anniversary of the date of grant. Generally, options terminate three
months after the optionee's termination of employment with the Company. The
Executive Compensation Committee of the Board of Directors may provide, however,
that an option may be exercised over a longer period following termination of
employment, but in no event beyond the expiration date of the option.

RESTRICTED STOCK AND UNIT PLAN

     The Company, with the Operating Partnership, maintains a restricted stock
and unit plan for executive officers and other key employees of the Company, the
Operating Partnership and the Property Service Businesses.  Messrs. Smith and
Kogod are not eligible to participate under the plan. A maximum of 300,000
shares of common stock and/or units may be issued under the plan.  Restricted
shares and/or units that have not vested at the time of an employee's
termination of employment with the Company will be forfeited, except where such
termination occurs by reason of death or disability. Any restricted shares
and/or units forfeited pursuant to the vesting provisions of the plan will again
be available for award under the plan. In July 1994, 95,000 restricted units
were awarded to certain executive officers and key employees.  These grants vest
in four equal annual installments beginning on the first anniversary of the date
of grant, subject to acceleration of vesting upon a change of control of the
Company.  During 1997, 24,000 grants were awarded and 20,700 units vested.
During 1996, 7,500 grants were canceled and 23,750 units vested. No grants were
canceled and 23,750 units vested in 1995. For the years ended December 31, 1997,
1996 and 1995, compensation expense relating to the plan was $0.6 million, $0.5
million and $0.6 million, respectively, based on the market value of the
Company's stock at the date of grant.

15.  OTHER LIMITED PARTNERS' INTEREST

     Limited partnership units of the Other Limited Partners may be redeemed at
the unitholders' discretion.   At the option of the Company, such redemption may
be made for cash, at the then fair value of the Company's stock, or for shares
of common stock of the Company on a one-for-one basis.  As of December 31, 1997,
approximately 18.7 million shares of the Company's authorized common stock had
been reserved for possible issuance upon redemption of limited partnership 
units.

     In accordance with generally accepted accounting principles, the Other
Limited Partners' redemption rights are not included in partner's equity.
Consequently, the accompanying consolidated balance sheets and statements of
partner's equity reflect the Other Limited Partners' Interest in the Operating
Partnership, measured at redemption value. Such interest is deducted from
partner's equity.


16.  SUBSEQUENT EVENTS (UNAUDITED)

     In January 1998, the Operating Partnership completed the acquisition of two
multifamily properties in northwest Washington, D.C. totaling 287 apartment
units.  The total cost of approximately $12.1 million was comprised of $3.3
million cash and 254,000 Operating Partnership units valued at approximately
$8.8 million.  One of the properties was an Affiliate in which the Operating
Partnership previously owned a 20% interest.  Both properties were previously
managed by the  Operating Partnership.

     In January 1998, the Operating Partnership finalized a contract to purchase
a 299-unit multifamily property located in the Crystal City submarket of
Arlington, Virginia. The acquisition is expected to close during the second
quarter of 1998. The purchase price of $39 million is expected to be funded from
the line of credit.

     In January 1998, the Company sold 500 shares of Series C Cumulative
Redeemable Preferred Stock ("Series C Preferred Shares"), $0.01 par value, for
$48.9 million, net of offering costs of $1.1 million. The net proceeds were
contributed to the Operating Partnership in exchange for 500 shares of Series C
Preferred Units. The Operating Partnership amended the Articles of Incorporation
to designate and establish the rights and privileges of the Series C Preferred
Unitholders which include certain voting, distribution and liquidation
preferences over the common unitholders. The Series C Preferred Units have a
liquidation preference of $100,000 per unit and an initial annual distribution
rate of $7,910 per unit. If the securities receive an investment grade rating,
the distribution rate will decrease by $250 per unit. Distributions are
cumulative and are payable quarterly. The Operating Partnership may redeem
Series C Preferred Units after February 1, 2028, at the liquidation price plus
accrued distributions.

     In February 1998, the  Operating Partnership terminated its existing $100
million line of credit and entered into a new $250 million, unsecured line of
credit with PNC Bank, Nations Bank, and U.S. Bank  which matures in March 2001.
Draws upon the new line are subject to certain unencumbered asset requirements
and bear interest at a selected LIBOR rate plus 75 to 110 basis points based on
the leverage ratio of the  Operating Partnership.  If the  Operating Partnership
receives an investment grade rating, the interest rate will decrease to 60 to 90
basis points over LIBOR based on the rating.  The  Operating Partnership repaid
the balance outstanding under the $100 million line and recognized an
extraordinary loss of $0.3 million related to the extinguishment of such debt.

     In March 1998, the  Operating Partnership sold a 227-unit multifamily
property located in southeast Washington, D.C. for $4.4 million.  The  Operating
Partnership recognized a gain on the sale of $3.2 million.

                        AGREEMENT OF LIMITED PARTNERSHIP
                                       OF
                    CHARLES E. SMITH RESIDENTIAL REALTY L.P.

       THIS TENTH AMENDMENT TO FIRST AMENDED AND RESTATED AGREEMENT OF LIMITED
PARTNERSHIP OF CHARLES E. SMITH RESIDENTIAL REALTY L.P. (this "TENTH
AMENDMENT"), dated as of October 3, 1997, is entered into by Charles E. Smith
Residential Realty, Inc., a Maryland corporation, as general partner (the
"GENERAL PARTNER") of Charles E. Smith Residential Realty L.P. (the

Partnership.

       WHEREAS, Section 4.2.B of the First Amended and Restated Agreement of
Limited Partnership of the Partnership (as heretofore amended, the "PARTNERSHIP
AGREEMENT") provides that the General Partner shall not issue additional
convertible securities containing the right to subscribe for or purchase shares
of Common Stock of the General Partner ("REIT SHARES" and collectively, the "NEW
SECURITIES"), other than to all holders of REIT Shares, unless the General
Partner causes the Partnership to issue to the General Partner Partnership
Interests having designations, preferences and other rights, all such that the
economic interests are substantially the same as those of the New Securities;

       WHEREAS, the General Partner has entered into a Purchase Agreement dated
as of September 17, 1997, pursuant to which the General Partner has agreed to
issue shares of Common Stock and a newly created series of capital stock,
designated Series B Cumulative Convertible Redeemable Preferred Stock (the
"SERIES B PREFERRED STOCK");

       WHEREAS, pursuant to the authority granted to the General Partner
pursuant to Section 4.2 of the Partnership Agreement, the General Partner
desires to amend the Partnership Agreement (i) to establish a new class of
Units, to be entitled Series B Cumulative Convertible Redeemable Preferred Units
(the "SERIES B PREFERRED UNITS"), and to set forth the designations, rights,
powers, preferences and duties of such Series B Preferred Units, which are
substantially the same as those of the Series B Preferred Stock, and (ii) to
make certain other changes to the Partnership Agreement;

       NOW, THEREFORE, in consideration of the premises and for other good and
valuable consideration, the receipt and sufficiency of which hereby are
acknowledged, the General Partner hereby amends the Partnership Agreement, as
follows:

       1. Section 4.2 of the Partnership Agreement is hereby amended by adding
after Section 4.2.D the following section:

            E. Series B Preferred Units.  Under the authority granted to
               ------------------------                                 
       it by Section 4.2.A hereof, the General Partner hereby establishes an
       additional class of Partnership Units entitled "Series B Cumulative
       Convertible Redeemable Preferred Units" (the "SERIES B PREFERRED UNITS").
       Series B Preferred Units shall have the designations, preferences,
       rights, powers and duties as set forth in Exhibit G hereto.
                                                 ---------

                       CHARLES E. SMITH RESIDENTIAL REALTY, INC.,
                       as General Partner of
                       Charles E. Smith Residential Realty L.P.
                       and on behalf of existing Limited Partners



                       By:

                       Title:

                                   EXHIBIT G

                   DESIGNATION OF THE PREFERENCES, CONVERSION
   AND OTHER RIGHTS, VOTING POWERS, RESTRICTIONS, LIMITATIONS AS TO SERIES B
                                PREFERRED UNITS

       The Series B Preferred Units shall have the following designations,
preferences, rights, powers and duties:

          (1) Certain Defined Terms.  The following capitalized terms used in
              ---------------------                                          
     this Exhibit G shall have the respective meanings set forth below:

          "DISTRIBUTION DATE" means (i) for any Distribution Period with respect
     to which the Partnership pays a distribution on the Class A Units, the date
     on which such distribution is paid, or (ii) for any Distribution Period
     with respect to which the Partnership does not pay a distribution on the
     Class A Units, the date set by the General Partner for payment of dividends
     on the Series B Preferred Stock.

          "DISTRIBUTION PERIOD" means quarterly periods commencing on January 1,
     April 1, July 1 and October 1 of each year and ending on and including the
     day preceding the first day of the next succeeding Distribution Period,
     except that: (i) the initial Distribution Period shall commence on July 1,
     1997 and end on and include September 30, 1997, and (ii) the Distribution
     Period during which any Series B Preferred Units shall be redeemed pursuant
     to Section 4 shall end on and include the date of such redemption.

          "FULLY JUNIOR UNITS" shall mean the Common Units and any other class
     or series of Partnership Units now or hereafter issued and outstanding over
     which the Series B Preferred Units have a preference or priority in both
     (i) the payment of dividends and (ii) the distribution of assets on any
     liquidation, dissolution or winding up of the Partnership.

          "JUNIOR UNITS" shall mean the Common Units and any other class or
     series of Partnership Units now or hereafter issued and outstanding over
     which the Series B Preferred Units have a preference or priority in either
     (i) the payment of dividends or (ii) the distribution of assets on any
     liquidation, dissolution or winding up of the Partnership.

          "PARITY UNITS" has the meaning ascribed thereto in Section 6(B).

          (2)  Distributions.
               ------------- 

          (A) The General Partner, in its capacity as the holder of the then
     outstanding Series B Preferred Units, shall be entitled to receive out of
     funds legally available therefor, when, as and if declared by the General
     Partner, distributions payable in cash at the rate per Series B Preferred
     Unit equal to the greater of (a) $2.02 per annum, prorated as described in
     Section 2(B), or (b) 

                                      G-1
<PAGE>
 
     the ordinary cash distributions (determined on each Distribution Date) paid
     on the number of Class A Units, or portion thereof, into which a Series B
     Preferred Unit is convertible. The distributions referred to in clause (b)
     of the preceding sentence shall equal the number of Class A Units, or
     portion thereof, into which a Series B Preferred Unit is convertible,
     multiplied by the most recent quarterly distribution on a Class A Unit on
     or before the applicable Distribution Date. If the Partnership pays an
     ordinary cash distribution on the Class A Units with respect to a
     Distribution Period after the date on which the Distribution Date is
     declared pursuant to clause (ii) of the definition of Distribution Date and
     the distribution calculated with respect to clause (b) of the first
     sentence of this Section 2(A) is greater than the distribution previously
     declared on the Series B Preferred Units with respect to such Distribution
     Period, the Partnership shall pay an additional distribution in respect of
     the Series B Preferred Units on the date on which the distribution on the
     Class A Units is paid, in an amount equal to the difference between (y) the
     distribution calculated pursuant to clause (b) of the first sentence of
     this Section 2(A) and (z) the amount of distributions previously declared
     on the Series B Preferred Units with respect to such Distribution Period.
     Distributions shall begin to accrue and shall be fully cumulative from
     September 30, 1997, whether or not in any Distribution Period or Periods
     there shall be funds of the Partnership legally available for the payment
     of such distributions, and shall be payable quarterly, when, as and if
     declared by the General Partner, in arrears on each Distribution Date.
     Accrued and unpaid distributions for any past Distribution Periods may be
     declared and paid at any time and for such interim periods, without
     reference to any regular Distribution Date, to the General Partner, on such
     date as may be fixed by the General Partner for payment of the
     corresponding dividend on the Series B Preferred Stock. Any distribution
     made on the Series B Preferred Units shall first be credited against the
     earliest accrued but unpaid distribution due with respect to Series B
     Preferred Units which remains payable.

          (B) The amount of distributions referred to in clause (a) of the first
     sentence of Section 2(A) shall be equal to $0.505.  The distribution
     payable with respect to the initial Distribution Period will include a full
     distribution for such Distribution Period notwithstanding the fact that the
     Series B Preferred Units were issued after September 30, 1997 (i.e., the
     greater of $0.505 per Series B Preferred Unit or the ordinary cash
     distribution paid on the Class A Units with respect to the quarterly period
     ending on or about September 30, 1997).  The amount of distribution for any
     period on the Series B Preferred Units that represents less than a full
     quarter of a year shall be computed on the basis of a 360-day year of
     twelve 30-day months and the actual number of days in such Distribution
     Period.  No interest, or sum of money in lieu of interest, shall be payable
     in respect of any distribution payment or payments on the Series B
     Preferred Units that may be in arrears.

          (C) So long as any Series B Preferred Units are outstanding, no
     distributions, except as described in the immediately following sentence,
     shall be declared or paid or set apart for payment on any class or series
     of Parity Units for any period unless full cumulative distributions have
     been or 

                                      G-2
<PAGE>
 
     contemporaneously are declared and paid or declared and a sum sufficient
     for the payment thereof set apart for such payment on the Series B
     Preferred Units for all Distribution Periods terminating on or prior to the
     distribution payment date for such class or series of Parity Units. When
     distributions are not paid full or a sum sufficient for such payment is not
     set apart, as aforesaid, all distributions declared upon Series B Preferred
     Units and all distributions declared upon any other class or series of
     Parity Units shall be declared ratably in proportion to the respective
     amounts of distributions accumulated and unpaid on the Series B Preferred
     Units and accumulated and unpaid on such Parity Units.

          (D) So long as any Series B Preferred Units are outstanding, no
     distributions (other than distributions paid solely in Fully Junior Units
     or options, warrants or rights to subscribe for or purchase Fully Junior
     Units) shall be declared or paid or set apart for payment or other
     distribution shall be declared or made or set apart for payment upon Junior
     Units, nor shall any Junior Units be redeemed, purchased or otherwise
     acquired (other than a redemption, purchase or other acquisition of Class A
     Units made for purposes of an employee incentive or benefit plan of the
     General Partner or any subsidiary) for any consideration (or any moneys be
     paid to or made available for a sinking fund for the redemption of any such
     Junior Units) by the Partnership, directly or indirectly (except by
     conversion into or exchange for Fully Junior Units), unless in each case
     (i) the full cumulative distributions on all outstanding Series B Preferred
     Units and any other Parity Units of the Partnership shall have been paid or
     declared and set apart for payment for all past Distribution Periods with
     respect to the Series B Preferred Units and all past distribution periods
     with respect to such Parity Units and (ii) sufficient funds shall have been
     paid or set apart for the payment of the distribution for the current
     Distribution Period with respect to the Series B Preferred Units and the
     current distribution period with respect to such Parity Units.

          (E) No distributions on the Series B Preferred Units shall be declared
     by the General Partner or paid or set apart for payment by the Partnership
     at such time as the terms and provisions of any agreement of the General
     Partner or the Partnership, including any agreement relating to
     indebtedness of either of them, prohibits such declaration, payment, or
     setting apart for payment or provides that such declaration, payment or
     setting apart for payment would constitute a breach thereof or a default
     thereunder, or if such declaration or payment shall be restricted or
     prohibited by law.

          (3)  Liquidation Preference.
               ---------------------- 

          (A) In the event of any liquidation, dissolution or winding up of the
     Partnership, whether voluntary or involuntary, before any payment or
     distribution of the assets of the Partnership shall be made to or set apart
     for the holders of Junior Units, the General Partner, in its capacity as
     holder of the Series B Preferred Units, shall be entitled to receive Twenty
     Eight Dollars and Fifty Cents ($28.50) (the "Series B Liquidation
     PreferencE") per Series B 

                                      G-3
<PAGE>
 
     Preferred Unit plus an amount equal to all distributions (whether or not
     earned or declared) accumulated, accrued and unpaid thereon to the date of
     final distribution to the General Partner, in its capacity as such holder;
     but the General Partner, in its capacity as the holder of Series B
     Preferred Units shall not be entitled to any further payment; provided that
     the distribution payable with respect to the Distribution Period containing
     the date of final distribution shall be equal to the greater of (i) the
     distribution provided in clause (a) of the first sentence of Section 2(A)
     or (ii) the distribution determined pursuant to clause (b) of the first
     sentence of Section 2(A) for the preceding Distribution Period. Until the
     holders of Series B Preferred Units have been paid, the Series B
     Liquidation Preference in full, no payment will be made to any holder of
     Junior Units upon the liquidation, dissolution, or winding up of the
     General Partner. If, upon any such liquidation, dissolution or winding up
     of the Partnership, the assets of the Partnership, or proceeds thereof,
     distributable to the General Partner, in its capacity as the holder of
     Series B Preferred Units, shall be insufficient to pay in full the
     preferential amount aforesaid and liquidating payments on any other class
     or series of Parity Units, then such assets, or the proceeds thereof, shall
     be distributed among the General Partner, in its capacity as the holder of
     such Series B Preferred Units, and the holders of such other Parity Units
     ratably in accordance with the respective amounts that would be payable on
     such Series B Preferred Units and such other Parity Units if all amounts
     payable thereon were paid in full. For the purposes of this Section 3, (x)
     a consolidation or merger of the Partnership with one or more partnerships,
     limited liability companies, corporations, real estate investment trusts or
     other entities and (y) a sale, lease or conveyance of all or substantially
     all of the Partnership's property or business shall not be deemed to be a
     liquidation, dissolution or winding up, voluntary or involuntary, of the
     Partnership.

          (B) Subject to the rights of the holders of Partnership Units of any
     Parity Units upon any liquidation, dissolution or winding up of the
     Partnership, after payment shall have been made in full to the General
     Partner, in its capacity as the holder of the Series B Preferred Units, as
     provided in this Section 3, any other series or class or classes of Junior
     Units shall, subject to any respective terms and provisions applying
     thereto, be entitled to receive any and all assets remaining to be paid or
     distributed, and the General Partner, in its capacity as the holder of the
     Series B Preferred Units, shall not be entitled to share therein.

          4.  Redemption Right.
              ---------------- 

          (A) Except as provided in Section 4(B), the Series B Preferred Units
     shall be redeemable by the General Partner, at its option, in whole or in
     part, for Class A Units, subject to the following conditions:

          (i)  The Series B Preferred Units shall be redeemed only if  the
               General Partner shall concurrently therewith redeem an equivalent
               number of shares of Series B Preferred Stock for REIT

                                      G-4
<PAGE>
 
               Shares. Such redemption of Series B Preferred Units shall occur
               substantially concurrently with the redemption by the General
               Partner of such Series B Preferred Shares (such date of
               redemption the "REDEMPTION DATE").

          (ii) In the event that the General Partner redeems shares of Series B
               Preferred Stock in exchange for REIT Shares, an equivalent number
               of Series B Preferred Units shall be converted into a number of
               Class A Units equal to (x) the number of REIT Shares issued by
               the General Partner in redemption of such shares of Series B
               Preferred Stock divided by (y) the Conversion Factor.

          (iii)  Upon any redemption of Series B Preferred Units, the
               Partnership shall pay in cash to the holder of such Units an
               amount equal to all accumulated, accrued and unpaid distributions
               with respect to the Series B Preferred Units being redeemed for
               any Distribution Period ending on or prior to the Redemption Date
               whether or not earned or declared.  Immediately prior to
               authorizing any redemption of the Series B Preferred Units, and
               as a condition precedent for such redemption, the General
               Partner, by resolution of its Board of Directors, shall declare a
               mandatory distribution on the Series B Preferred Units, payable
               in cash on the Redemption Date in an amount equal to all
               accumulated, accrued, and unpaid distributions as of the
               Redemption Date on the Series B Preferred Units to be redeemed,
               which amount shall be added to the redemption price, except to
               the extent such distributions are to be paid pursuant to the
               immediately following sentence.  If the Redemption Date falls
               after a Partnership Record Date and prior to the corresponding
               Distribution Date, then the General Partner, in its capacity as
               the holder of the Series B Preferred Units being redeemed, shall
               be entitled to distributions payable on the corresponding
               Distribution Date notwithstanding the redemption of such Series B
               Preferred Units prior to such Distribution Date.  Except as
               provided above, the Partnership shall make no payment or
               allowance for accumulated or accrued distributions on Series B
               Preferred Units called for redemption or on the Class A Units
               issued upon such redemption.

          (iv) Any Class A Unit issued upon redemption of the Series B Preferred
               Units shall be validly issued, fully paid and non-assessable.

          (B) In the event that the General Partner is required to redeem any
     shares of Series B Preferred Stock pursuant to the terms thereof, the
     Partnership shall redeem an equivalent number of Series B Preferred Units
     for consideration equal to the consideration payable by the General Partner
     upon redemption of such shares of Series B Preferred Stock.

          5.  Conversion to Class A Units.
              --------------------------- 

          (A) In the event that a holder of Series B Preferred Stock exercises
     its right to convert such Series B Preferred Stock into REIT Shares, then,
     concurrently therewith, an equivalent number of Series B Preferred Units
     shall be automatically converted into a number of Class A Units equal to
     (x) the number of REIT Shares issued upon conversion of such Series B
     Preferred Shares divided by (y) the Conversion Factor.  Any such conversion
     will be effective at the same time as the conversion of Series B Preferred
     Stock into REIT Shares is effective.

          (B) The General Partner, in its capacity as the holder of Series B
     Preferred Units that are converted pursuant to this Section 4 effective
     during the period after a Partnership Record Date with respect to the
     Series B Preferred Shares and prior to the opening of business on the
     distribution payment record date with respect to the Class A Units for the
     corresponding Distribution Date, shall not be entitled to receive the
     distribution payable on such Series B Preferred Units on such Distribution
     Date notwithstanding such conversion thereof following the corresponding
     Partnership Record Date and prior to such Distribution Date.

          6.  Ranking.  Any class or series of  Partnership Units shall be
              -------                                                     
     deemed to rank:

          (A) prior to the Series B Preferred Units, as to the payment of
     distributions and as to distribution of assets upon liquidation,
     dissolution or winding up of the Partnership, if the holders of such class
     or series of Partnership Units shall be entitled to the receipt of
     distributions or of amounts distributable upon liquidation, dissolution or
     winding up, as the case may be, in preference or priority to the holders of
     Series B Preferred Units;

          (B) on a parity with the Series B Preferred Units as to the payment of
     distributions and as to the distribution of assets upon liquidation,
     dissolution or winding up of the Partnership, whether or not the
     distribution rates, distribution payment dates or redemption or liquidation
     prices per Partnership Unit be different from those of the Series B
     Preferred Units, if the holders of such class or series of Partnership
     Units and the Series B Preferred Units shall be entitled to the receipt of
     distributions and of amounts distributable upon liquidation, dissolution or
     winding up in proportion to their respective amounts of accrued and unpaid
     distributions per Partnership Unit or liquidation preferences, without
     preference or priority one over the other ("PARITY UNITS"); the outstanding
     Series A Cumulative Convertible Redeemable Preferred Units of the General
     Partner are Parity Units;

          (C) junior to the Series B Preferred Units, as to the payment of
     distributions or as to the distribution of assets upon liquidation,
     dissolution 

                                      G-6
<PAGE>
 
     or winding up of the Partnership, if such class or series of
     Partnership Units shall be Junior Units; and

          (D) junior to the Series B Preferred Units, as to the payment of
     distributions and as to the distribution of assets upon liquidation,
     dissolution or winding up of the Partnership, if such class or series of
     Partnership Units shall be Fully Junior Units;

          7.  Voting.  Except as required by law, the General Partner, in its
              ------                                                         
     capacity  as the holder of the Series B Preferred Units, shall not be
     entitled to vote at any meeting of the Partners or for any other purpose or
     otherwise to participate in any action taken by the Partnership or the
     Partners, or to receive notice of any meeting of the Partners.

          8.  Restriction on Ownership.  The Series B Preferred Units shall be
              ------------------------                                        
     owned and held solely by the General Partner.

          9.  General.  The rights of the General Partner, in its capacity as
              -------                                                        
     the holder of the Series B Preferred Units, are in addition to and not in
     limitation on any other rights or authority of the General Partner, in any
     other capacity, under the Agreement.  In addition, nothing contained in
     this Exhibit G shall be deemed to limit or otherwise restrict any rights or
          ---------                                                             
     authority of the General Partner under the Agreement, other than in its
     capacity as the holder of the Series B Preferred Units.

     SECTION 2.1.  Commitments to Lend.
                   ------------------- 

     (a)  Each Bank severally agrees, on the terms and conditions set forth in
this Agreement, to make Loans to the Borrower and participate in Letters of
Credit issued by the Fronting Bank on behalf of the Banks pursuant to this
Article II from time to time during the term hereof in amounts such that the
aggregate principal amount of Committed Loans by such Bank at any one time
outstanding together with such Bank's pro rata share of the Letter of Credit
Usage shall not exceed the amount of its Commitment, provided that in no event
shall the aggregate amount of the Loans then outstanding and Letter of Credit
Usage, exceed the Loan Availability.  Each Borrowing under this Section 2.1
shall be in an aggregate principal amount of $1,000,000 or an integral multiple
of $100,000 in excess thereof (except that any such Borrowing may be in the
aggregate amount available in accordance with Section 3.2(b) or in any amount
required to reimburse the Fronting Bank for any drawing under any Letter of
Credit) and, other than with respect to Money Market Loans, shall be made from
the several Banks ratably in proportion to their respective Commitments.
Subject to the limitations set forth herein, any amounts repaid may be
reborrowed.

     (b)  If at any time the outstanding principal balance of the Loans and the
Letter of Credit Usage exceeds the Loan Availability, Borrower shall submit to
the Administrative Agent, not later than fifteen (15) days following written
notice from the Administrative Agent to Borrower (a copy of which shall be sent
promptly by the Administrative Agent to each Bank) of the existence of such
excess borrowing condition, a written plan pursuant to which Borrower shall
cause such excess borrowing condition to be eliminated not later than thirty
(30) days following such notice from the Administrative Agent to the Borrower,
through one or both of the following means: Borrower shall (A) pay to the
Administrative Agent such amounts and/or (B) designate to the Administrative
Agent such additional Qualifying Unencumbered Properties as may be acceptable
under Section 5.14 as are necessary so that the outstanding principal balance of
the Loans and the Letter of Credit Usage does not exceed the Loan Availability.
Failure by Borrower to have complied with the foregoing in a timely manner shall
constitute an Event of Default without further notice or grace period hereunder.
No further Borrowings shall be permitted, and the Borrower shall not cause or
allow any existing Qualifying Unencumbered Property to no longer be a Qualifying
Unencumbered Property, so long as such excess borrowing condition shall continue
to exist.  Nothing in this Section 2.1(b) shall excuse Borrower's compliance
with all terms, conditions, covenants and other obligations imposed upon it
under the Loan Documents during the period of such excess borrowing, nor in any
manner condition or impair the Banks' rights thereunder in respect of any such
breach thereof by Borrower.

of Credit to be issued, (iv) the date of such issuance (which shall be a

(vii) the purpose and circumstances for which such Letter of Credit is being
issued and (viii) the terms upon which each such Letter of Credit may be drawn
down (which terms shall not leave any discretion to Fronting Bank), including,
if available, a proposed form of the Letter of Credit.  Each such notice may be
revoked telephonically by the Borrower to the applicable Fronting Bank and the
Administrative Agent any time prior to the date of issuance of the Letter of
Credit by the applicable Fronting Bank, provided such revocation is confirmed in
writing by the Borrower to the Fronting Bank and the Administrative Agent within
one (1) Domestic Business Day by facsimile.  No later than 10:00 a.m.,
Pittsburgh  time, on the date that is four (4) Domestic Business Days prior to
the date of issuance, the Borrower shall specify a precise description of the
documents and the verbatim text of any certificate to be presented by the
beneficiary of such Letter of Credit, which if presented by such beneficiary
prior to the expiration date of the Letter of Credit would require the Fronting
Bank to make a payment under the Letter of Credit; provided, that Fronting Bank
may, in its reasonable judgment, require changes in any such documents and
certificates only in conformity with customary and commercially reasonable
practice or law and, provided further, that no Letter of Credit shall require
payment against a conforming draft to be made thereunder before the third
Domestic Business Day following the date that such 

                                       30

draft is presented if such presentation is made later than 10:00 A.M. Pittsburgh
time. The Borrower shall further deliver to the Fronting Bank such additional
instruments and documents as the Fronting Bank may reasonably require in
conformity with the commercially reasonable practices of its letter of credit
department, in connection with the issuance of such Letter of Credit. At the
time that each Letter of Credit is issued, Borrower shall pay to the
Administrative Agent for the benefit of Fronting Bank an issuance fee, to be
retained by the Fronting Bank with no obligation to share with any other Bank,
with respect to each Letter of Credit issued in an amount equal to Five Hundred
Dollars ($500). In determining whether to pay on such Letter of Credit, the
Fronting Bank shall be responsible only to determine that the documents and
certificates required to be delivered under the Letter of Credit have been
delivered and that they substantially comply on their face with the requirements
of that Letter of Credit.

          (a)  The Money Market Option.  From time to time during the Term
               -----------------------                                    
following the end of the Syndication Period, and provided that at such time
either Borrower or CESRRI maintains the Investment Grade Ratings, the Borrower
may, as set forth in this Section 2.3, request the Banks during the Term to make
offers to make Money Market Loans to the Borrower, provided that the aggregate

any amounts so repaid may be reborrowed, up to the amount available under this
Section 2.3 or under Section 2.1, as applicable, at the time of such Borrowing,
until the Domestic Business Day next preceding the Maturity Date. The Banks may,
but shall have no obligation to, make such offers and the Borrower may, but
shall have no obligation to, accept any such offers in the manner set forth in
this Section 2.3.

          (b)  Money Market Quote Request.  When the Borrower wishes to request
               --------------------------                                      
offers to make Money Market Loans under this Section 2.3, it shall transmit to

Business Day in the case of a LIBOR Auction or a Domestic Business Day in the
case of an Absolute Rate Auction,

          (ii) the aggregate amount of such Borrowing, which shall be $3,000,000
or a larger multiple of $100,000,

                                       31
<PAGE>
 
          (iii) the duration of the Interest Period applicable thereto
(which shall not be less than 14 days or more than 180 days), subject to the

          (iv)  whether the Money Market Quotes requested are to set forth a
Money Market Margin or a Money Market Absolute Rate,

number of days as the Borrower and the Administrative Agent may agree) of any
other Money Market Quote Request, and no more than two (2)  Money Market Quote
Requests may be submitted within any calendar month.  There shall be no more
than five (5) Money Market Loans outstanding at any one time.  To the extent
that any such Borrowing would result in the outstanding Loans exceeding Loan
Availability, as based upon the most recent Compliance Certificate but also
taking into account additional Unsecured Debt which has been incurred subsequent
to the most recent Compliance Certificate, a Compliance Certificate in
accordance with Section 5.8(l) shall be delivered with the applicable Money
Market Loan Request.

          (c)   Invitation for Money Market Quotes.  Promptly upon receipt of a
                ----------------------------------                             
Money Market Quote Request, the Administrative Agent shall send to the Banks by
telex or facsimile transmission an Invitation for Money Market Quotes
substantially in the form of Exhibit C hereto or such replacement form as may be
delivered by the Administrative Agent, which shall constitute an invitation by

                --------------------------------------- ------ 

          (i)   Each Bank may submit a Money Market Quote containing an offer or
offers to make Money Market Loans in response to any Invitation for Money Market

offer or offers contained therein not later than (x) one hour prior to the
deadline for the other Banks, in the case of a LIBOR Auction or (y) 15 minutes
prior to the deadline for the other Banks, in the case of an Absolute Rate

irrevocable except with 

                                       32
<PAGE>
 
the written consent of the Administrative Agent given on the instructions of the
Borrower. Such Money Market Loans may be funded by such Bank's Designated Lender
(if any) as provided in Section 9.6(d), however such Bank shall not be required
to specify in its Money Market Quote whether such Money Market Loans will be
funded by such Designated Lender.

          (ii)  Each Money Market Quote shall be in substantially the form of
Exhibit D hereto and shall in any case specify:

                (A)  the proposed date of Borrowing,

                (B)  the principal amount of the Money Market Loan for which
each such offer is being made, which principal amount (w) may be greater than or
less than the Commitment of the quoting Bank, (x) must be $3,000,000 or a larger
multiple of $100,000, (y) may not exceed the principal amount of Money Market
Loans for which offers were requested and (z) may be subject to an aggregate
limitation as to the principal amount of Money Market Loans for which offers
being made by such quoting Bank may be accepted,

                (C)  in the case of a LIBOR Auction, the margin above or below

                (D)  in the case of an Absolute Rate Auction, the fixed rate of

A Money Market Quote may set forth up to five (5) separate offers by the quoting
Bank with respect to each Interest Period specified in the related Invitation
for Money Market Quotes.

          (iii) Any Money Market Quote shall be disregarded by the
Administrative Agent if it:

                (A) is not substantially in conformity with Exhibit D hereto or
does not specify all of the information required by Section 2.3(d)(ii) above;

                (B) contains qualifying, conditional or similar language (except
for an aggregate limitation as provided in Section 2.3(d)(ii)(B) above);

                (C) proposes terms other than or in addition to those set forth
in the applicable Invitation for Money Market Quotes; or

                (D) arrives after the time set forth in Section 2.3(d)(i).

                                       33
<PAGE>
 
          (e)   Notice to Borrower.  The Administrative Agent shall promptly
                ------------------
(and in any event within one (1) Domestic Business Day) notify the Borrower in
writing of the terms (x) of any Money Market Quote submitted by a Bank that is
in accordance with Section 2.3(d) and (y) of any Money Market Quote that amends,
modifies or is otherwise inconsistent with a previous Money Market Quote
submitted by such Bank with respect to the same Money Market Quote Request. Any
such subsequent Money Market Quote shall be disregarded by the Administrative
Agent unless such subsequent Money Market Quote is submitted solely to correct a
manifest error in such former Money Market Quote or modifies the terms of such
previous Money Market Quote to provide terms more favorable to Borrower. The
Administrative Agent's notice to the Borrower shall specify (A) the aggregate
principal amount of Money Market Loans for which offers have been received for
each Interest Period specified in the related Money Market Quote Request, (B)
the respective principal amounts and Money Market Margins or Money Market
Absolute Rates, as the case may be, so offered and (C) if applicable,
limitations on the aggregate principal amount of Money Market Loans for which
offers in any single Money Market Quote may be accepted.

          (f)   Acceptance and Notice by Borrower.  Not later than 10:30 A.M.
                ---------------------------------                            
Pittsburgh time on (x) the third Euro-Dollar Business Day prior to the proposed
date of Borrowing, in the case of a LIBOR Auction or (y) the proposed date of
Borrowing, in the case of an Absolute Rate Auction, the Borrower shall notify
the Administrative Agent of its acceptance or non-acceptance of the offers
communicated to it pursuant to subsection (e).  In the case of acceptance, such
notice (a "Notice of Money Market Borrowing") shall specify the aggregate
principal amount of offers for each Interest Period that are accepted.  The
Borrower may accept any Money Market Quote in whole or in part; provided that:

          (i)   the aggregate principal amount of each Money Market Borrowing
may not exceed the applicable amount set forth in the related Money Market Quote
Request;

          (ii)  the principal amount of each Money Market Borrowing must be
$3,000,000 or a larger multiple of $100,000 ;

          (iii) acceptance of offers may only be made on the basis of ascending
Money Market Margins or Money Market Absolute Rates, as the case may be; and

          (iv)  the Borrower may not accept any offer that is described in
Section 2.3(d)(iii) or that otherwise fails to comply with the requirements of
this Agreement.

          (g)   Allocation by Administrative Agent.  If offers are made by two
                ----------------------------------      
or more Banks with the same Money Market Margins or Money Market Absolute Rates,
as the case may be, for a greater aggregate principal amount than the amount in
respect of which such offers are accepted for the related Interest Period, the
principal amount of Money Market Loans in respect of which such offers are
accepted shall be allocated by the Administrative Agent among such Banks as
nearly as possible (in multiples of $100,000, as the Administrative Agent may
deem appropriate) in proportion to the aggregate principal amounts of such
offers. The Administrative Agent shall promptly notify the Borrower and each
such Bank in writing of any such allocation of Money Market Loans.
Determinations by the Administrative Agent of the allocation of Money Market
Loans shall be 

                                       34
<PAGE>
 
conclusive in the absence of manifest error.

          (h) Notification by Administrative Agent.  Upon receipt of the
              ------------------------------------                      
Borrower's Notice of Money Market Borrowing in accordance with Section 2.3(f)
hereof, the Administrative Agent shall promptly notify each Bank of the
principal amount of the Money Market Borrowing accepted by the Borrower and of
such Bank's share (if any) of such Money Market Borrowing and such Notice of
Money Market Borrowing shall not thereafter be revocable by the Borrower.  A
Bank who is notified that it has been selected to make a Money Market Loan may
designate its Designated Lender (if any) to fund such Money Market Loan on its
behalf, as described in Section 9.6(d). Any Designated Lender which funds a
Money Market Loan shall on and after the time of such funding become the obligee
under such Money Market Loan and be entitled to receive payment when due.  No
Bank shall be relieved of its obligation to fund a Money Market Loan, and no
Designated Lender shall assume such obligation, prior to the time the applicable
Money Market Loan is funded.

          (i) Funding of Pro Rata Shares.  Notwithstanding anything to the
              --------------------------                                  
contrary contained herein, each Bank shall be required to fund its pro rata
share of Committed Loans in accordance with Section 2.1 hereof despite the fact
that such Bank's Commitment may have been or may be exceeded as a result of such
Bank's making of Money Market Loans.

     SECTION 2.4.  Notice to Banks; Funding of Loans.
                   --------------------------------- 

          (a) Upon receipt of a notice from Borrower in accordance with Section
2.2 hereof (each such notice being a "Notice of Borrowing") in the form of
Exhibit I attached hereto, and, if the amount of the Borrowing would result in
the outstanding Loans exceeding Loan Availability, based upon the most recent
Compliance Certificate but also taking into account any additional Unsecured
Debt which has been incurred subsequent to the most recent Compliance
Certificate, an updated Compliance Certificate in accordance with Section 5.8(l)
shall be delivered simultaneously therewith, the Administrative Agent shall, on
the date such Notice of Borrowing is received by the Administrative Agent, send
each Bank a copy of the Notice of Borrowing and, if applicable, the Compliance
Certificate, and notify each Bank of such Bank's share of such Borrowing, of the
interest rate determined pursuant thereto and the Interest Period(s) and such
Notice of Borrowing shall not thereafter be revocable by the Borrower, unless
Borrower shall pay any applicable expenses pursuant to Section 2.13.

          (b) Not later than 1:00 p.m. Pittsburgh  time on the date of each
Borrowing as indicated in the Notice of Borrowing, each Bank shall make
available its share of such Borrowing in Federal funds immediately available in
Pittsburgh, Pennsylvania, to the Administrative Agent at its address referred to
in Section 9.1. If the Borrower has requested the issuance of a Letter of
Credit, no later than 12:00 Noon Pittsburgh  time on the date of such issuance
as indicated in the notice delivered pursuant to Section 2.2(b), the Fronting
Bank shall issue such Letter of Credit in the amount so requested and deliver
the same to or as directed by the Borrower with a copy thereof to the
Administrative Agent.  Promptly following receipt of a copy of each Letter of
Credit, Administrative Agent shall deliver a copy thereof to each Bank.
Immediately upon the issuance of each Letter of Credit by the Fronting Bank,
such Fronting Bank shall be deemed to have sold and transferred to each  other
Bank, and each such other Bank shall be deemed, and hereby agrees, to 

                                       35
<PAGE>
 
have irrevocably and unconditionally purchased and received from the Fronting
Bank, without recourse or warranty, an undivided interest and a participation in
such Letter of Credit, any drawing thereunder, and the obligations of the
Borrower hereunder with respect thereto, and any security therefor or guaranty
pertaining thereto, in an amount equal to such Bank's ratable share thereof
(based upon the ratio its Commitment bears to the aggregate of all Commitments).
Upon any change in any of the Commitments in accordance herewith, there shall be
an automatic adjustment to such participations to reflect such changed shares.
The Fronting Bank shall have the primary obligation to fund any and all draws
made with respect to such Letter of Credit notwithstanding any failure of a
participating Bank to fund its ratable share of any such draw. The
Administrative Agent will instruct the Fronting Bank to make such Letter of
Credit available to or as directed by the Borrower and the Fronting Bank shall
make such Letter of Credit available to or as directed by the Borrower at the
Borrower's aforesaid address or at such address in the United States as Borrower
shall request on the date of the Borrowing.

          (c) Unless the Administrative Agent shall have received notice from a
Bank prior to the date of any Borrowing that such Bank will not make available
to the Administrative Agent such Bank's share of such Borrowing, the
Administrative Agent may assume that such Bank has made such share available to
the Administrative Agent on the date of such Borrowing in accordance with
Section 2.4(b), and the Administrative Agent may, in reliance upon such
assumption, but shall not be obligated to, make available to the Borrower on
such date a corresponding amount on behalf of such Bank.  If and to the extent
that such Bank shall not have so made such share available to the Administrative
Agent, such Bank and the Borrower severally agree to repay to the Administrative
Agent forthwith on demand, and in the case of the Borrower one (1)  Domestic
Business Day after demand, such corresponding amount together with interest
thereon, for each day from the date such amount is made available to the
Borrower until the date such amount is repaid to the Administrative Agent, at
(i) in the case of the Borrower, a rate per annum equal to the interest rate
applicable thereto pursuant to Section 2.7 and (ii) in the case of such Bank,
the Federal Funds Rate.  If such Bank shall repay to the Administrative Agent
such corresponding amount, such amount so repaid shall constitute such Bank's
Loan included in such Borrowing for the purposes of this Agreement.

          (d) The failure of any Bank to make available to the Administrative
Agent its share of any Borrowing shall not relieve any other Bank of its
obligation to fund its share of such Borrowing.

     SECTION 2.5.  Notes.
                   ----- 

          (a) The Base Rate Loans and the Euro-Dollar Loans of each Bank shall
be evidenced by a single Revolving Credit Note in the amount of its Commitment
payable to the order of such Bank for the account of its Applicable Lending
Office.  The Money Market Loans of each Bank, including each Designated Lender,
shall be evidenced by a single Bid Rate Note in the amount of $125,000,000,
payable to the order of such Bank for the account of its Applicable Lending
Office.

          (b) Each Bank may, by notice to the Borrower and the Administrative
Agent, request that its Loans of a particular type (including Money Market
Loans) be evidenced by a separate Note in an amount equal to the aggregate
unpaid principal amount of such Loans.  Any 

                                       36
<PAGE>
 
additional costs incurred by the Administrative Agent, the Borrower or the Banks
in connection with preparing such a Note shall be at the sole cost and expense
of the Bank requesting such Note. In the event any Loans evidenced by such a
Note are paid in full prior to the Maturity Date, any such Bank shall return
such Note to Borrower. Each such Note shall be in substantially the form of
Exhibit A-2 hereto (or in the case of a Money Market Loan, in substantially the
form of Exhibit A-1 hereto) with appropriate modifications to reflect the fact
that it evidences solely Loans of the relevant type. Upon the execution and
delivery of any such Note, any existing Note payable to such Bank shall be
replaced or modified accordingly. Each reference in this Agreement to the "Note"
of such Bank shall be deemed to refer to and include any or all of such Notes,
as the context may require.

          (c) Upon receipt of each Bank's Note pursuant to Section 3.1(a), the
Administrative Agent shall forward such Note to such Bank.  Each Bank shall
record the date, amount, type and maturity of each Loan made by it and the date
and amount of each payment of principal made by the Borrower with respect
thereto, and may, if such Bank so elects in connection with any transfer or
enforcement of its Note, endorse on the appropriate schedule appropriate
notations to evidence the foregoing information with respect to each such Loan
then outstanding; provided that the failure of any Bank to make any such
recordation or endorsement shall not affect the obligations of the Borrower
hereunder or under the Notes.  Each Bank is hereby irrevocably authorized by the
Borrower to so endorse its Note and to attach to and make a part of its Note a
continuation of any such schedule as and when required.

          (d) The Committed Loans shall mature, and the principal amount thereof
shall be due and payable, on the Maturity Date.

          (e) Each Money Market Loan included in any Money Market Borrowing
shall mature, and the principal amount thereof shall be due and payable,
together with accrued interest thereon, on the earlier to occur of (i) the last
day of the Interest Period applicable to such Money Market Borrowing or (ii) the
Maturity Date.

          (f) There shall be no more than ten (10) Euro-Dollar Groups of Loans
outstanding at any one time.

     SECTION 2.6.  Method of Electing Interest Rates.
                   --------------------------------- 

          (a)  The Loans included in each Committed Borrowing shall bear
interest initially at the type of rate specified by the Borrower in the
applicable Notice of Borrowing. Thereafter, the Borrower may from time to time
elect to change or continue the type of interest rate borne by each Group of
Loans (subject in each case to the provisions of Article VIII), as follows:

               (i)  if such Loans are Base Rate Loans, the Borrower may elect to
          convert all or any portion of such Loans to Euro-Dollar Loans as of
          any Euro-Dollar Business Day;

               (ii) if such Loans are Euro-Dollar Loans, the Borrower may elect
          to convert all or any portion of such Loans to Base Rate Loans and/or
          elect to continue

                                       37
<PAGE>
 
          all or any portion of such Loans as Euro-Dollar Loans for an
          additional Interest Period or additional Interest Periods, in each
          case effective on the last day of the then current Interest Period
          applicable to such Loans, or on such other date designated by Borrower
          in the Notice of Interest Rate Election provided Borrower shall pay
          any losses pursuant to Section 2.13.

Each such election shall be made by delivering a notice (a "Notice of Interest
Rate Election") to the Administrative Agent on or before 11:00 a.m. Pittsburgh
time at least three (3) Euro-Dollar Business Days before the conversion or
continuation selected in such notice is to be effective.  A Notice of Interest
Rate Election may, if it so specifies, apply to only a portion of the aggregate
principal amount of the relevant Group of Loans; provided that (i) such portion
is allocated ratably among the Loans comprising such Group, (ii) the portion to
which such Notice of Interest Rate Election applies, and the remaining portion
to which it does not apply, are each $1,000,000 or any larger multiple of
$100,000, (iii) there shall be no more than ten (10) Euro-Dollar Groups of Loans
outstanding at any time, (iv) no Committed Loan may be continued as, or
converted into, a Euro-Dollar Loan when any Default or Event of Default has
occurred and is continuing, and (v) no Interest Period shall extend beyond the
Maturity Date.

          (b)  Each Notice of Interest Rate Election shall specify:

               (i)    the Group of Loans (or portion thereof) to which such
          notice applies;

               (ii)   the date on which the conversion or continuation selected
          in such notice is to be effective, which shall comply with the
          applicable clause of subsection (a) above;

               (iii)  if the Loans comprising such Group are to be converted,
          the new type of Loans and, if such new Loans are Euro-Dollar Loans,
          the duration of the initial Interest Period applicable thereto; and

               (iv)   if such Loans are to be continued as Euro-Dollar Loans for
          an additional Interest Period, the duration of such additional
          Interest Period.

Each Interest Period specified in a Notice of Interest Rate Election shall
comply with the provisions of the definition of Interest Period.

          (c) Upon receipt of a Notice of Interest Rate Election from the
Borrower pursuant to subsection (a) above, the Administrative Agent shall notify
each Bank the same day as it receives such Notice of Interest Rate Election of
the contents thereof, and the Interest Periods (if different from those
requested by the Borrower) and such notice shall not thereafter be revocable by
the Borrower.  If the Borrower fails to deliver a timely Notice of Interest Rate
Election to the Administrative Agent for any Euro-Dollar Group of Loans, such
Euro-Dollar Group of Loans shall be converted into Base Rate Loans on the last
day of the then current Interest Period applicable thereto.

          (d) If the Borrower shall fail to pay any principal of or interest on
any Money Market Loan when due, such Money Market Loan shall bear interest,
payable on demand, for each day until paid at a rate per annum equal to the Base
Rate until such failure shall become an Event of Default and thereafter at a
rate per annum equal to the sum of 4% plus the Base Rate for such day (the
"Default Rate").

     SECTION 2.7.  Interest Rates.
                   -------------- 

          (a) Each Base Rate Loan shall bear interest on the outstanding
principal amount thereof, for each day from the date such Loan is made until the
date it is repaid or converted into a Euro-Dollar Loan pursuant to Section 2.6
or at the Maturity Date, at a rate per annum equal to the Base Rate plus the
Applicable Margin for Base Rate Loans for such day.  Such interest shall be
payable on the first day of each calendar month.

          (b) Each Euro-Dollar Loan shall bear interest on the outstanding
principal amount thereof, for each day during the Interest Period applicable
thereto, at a rate per annum equal to the sum of the Applicable Margin for Euro-
Dollar Loans for such day plus the Adjusted London Interbank Offered Rate
applicable to such Interest Period.  Such interest shall be payable for each
Interest Period on the  first day of each calendar month.

     The "Adjusted London Interbank Offered Rate" applicable to any Interest
          --------------------------------------                            
Period means a rate per annum equal to the quotient obtained (rounded upward, if
necessary, to the next higher 1/100th of 1%) by dividing (i) the London
Interbank Offered Rate applicable during such Interest Period by (ii) 1.00 minus
the Euro-Dollar Reserve Percentage.

     The "London Interbank Offered Rate" applicable to any Interest Period means
          ------------------------------                                        
the rate per annum (rounded upward, if necessary, to the next higher 1/100th of
1%) determined by the Administrative Agent in accordance with its usual
procedures (which determination shall be conclusive absent manifest error) to be
the average of the London interbank offered rates for U.S. Dollars quoted by the
British Bankers' Association as set forth on Dow Jones Markets Service (formerly
known as Telerate) display page 3750 (or appropriate successor or, if British
Bankers' Association or its successor ceases to provide such quotes, a
comparable replacement determined by the Administrative Agent) two (2) Euro-
Dollar Business Days before the first day of such Interest Period in an amount
approximately equal to the principal amount of the Euro-Dollar Borrowing or
Group of Loans or portion thereof to be converted into or continued as Euro-
Dollar Loans to which such Interest Period is to apply and for a period of time
comparable to such Interest Period.

     "Euro-Dollar Reserve Percentage" means for any day that percentage
      ------------------------------                                   
(expressed as a decimal) which is in effect on such day, as prescribed by the
Board of Governors of the Federal Reserve System (or any successor) under
Regulation D, as Regulation D may be amended, modified or supplemented, for
determining the maximum reserve requirement for a member bank of the Federal
Reserve System in New York City with deposits exceeding five billion dollars in
respect of "Euro-Currency liabilities" (or in respect of any other category of
liabilities which includes deposits by reference to which the interest rate on
Euro-Dollar Loans is determined or any category of extensions of credit or other
assets which includes loans by a non-United States office of any Bank

to United States residents). The Adjusted London Interbank Offered Rate shall be
adjusted automatically on and as of the effective date of any change in the 
Euro-Dollar Reserve Percentage.

          (c) Subject to Section 8.1, each Money Market LIBOR Loan shall bear
interest on the outstanding principal amount thereof, for the Interest Period
applicable thereto, at a rate per annum equal to the sum of the London Interbank
Offered Rate for such Interest Period (determined in accordance with Section
2.7(b) as if the related Money Market LIBOR Borrowing were a Euro-Dollar
Borrowing) plus, or minus, the Money Market Margin quoted by the Bank making
such Loan in accordance with Section 2.3. Each Money Market Absolute Rate Loan
shall bear interest on the outstanding principal amount thereof, for the
Interest Period applicable thereto, at a rate per annum equal to the Money
Market Absolute Rate quoted by the Bank making such Loan in accordance with
Section 2.3. Such interest shall be payable for each Interest Period on the last
day thereof, except as may be otherwise agreed among Borrower, Administrative
Agent and the applicable Bank, but in no event shall interest be payable at any
interval shorter than one month.  Any overdue principal of or interest on any
Money Market Loan shall bear interest, payable on demand, for each day until
paid at a rate per annum equal to the Base Rate until such failure shall become
an Event of Default and thereafter during the continuance of such Event of
Default at a rate per annum equal to the Default Rate.

          (d) In the event that, and for so long as, any Event of Default shall
have occurred and be continuing, the outstanding principal amount of the Loans,
and, to the extent permitted by applicable law, overdue interest in respect of
all Loans, shall bear interest at the Default Rate.

          (e) The Administrative Agent shall determine each interest rate
applicable to the Loans hereunder.  The Administrative Agent shall give prompt
notice to the Borrower and the Banks of each rate of interest so determined, and
its determination thereof shall be conclusive in the absence of demonstrable
error.

     SECTION 2.8.  Fees.

not maintained, the Borrower shall pay to the Administrative Agent for the
account of the Banks ratably in proportion to their respective Commitments a
facility fee (the "Facility Fee") on the aggregate Commitments at the respective
percentages per annum based upon the range into which the Borrower's Leverage
Ratio then falls, in accordance with the following table.  Any change in
Borrower's Leverage Ratio causing it to move to a different range on the table
shall effect an immediate change in the Facility Fee, effective on the earlier
of (i) the date of the Compliance Certificate reflecting such change in the
Leverage Ratio, or (ii) the end of the calendar quarter to which such Compliance
Certificate is related, if applicable.

     During any time when either CESRRI or Borrower shall maintain the
Investment Grade Ratings, "Facility Fee" shall mean a facility fee on the
aggregate Commitments at the respective percentages per annum based upon the
Credit Ratings then applicable in accordance with the following table.

</TABLE>

Any change in Credit Rating causing it to move into a different range on the
table shall effect an immediate change in the applicable percentage per annum.
If CESRRI or  Borrower shall maintain two (2) Credit Ratings, and such ratings
are not equivalent, the Facility Fee shall be based upon the lower of such
Credit Ratings.  In the event that CESRRI or Borrower receives more than two (2)
Credit Ratings, and such ratings are not equivalent, the Facility Fee shall be
determined by the lower of the two (2) highest ratings, provided that at least
one of such highest Credit Ratings shall be from S&P or Moody's.  In the event
that at least one of the two (2) highest ratings shall not be a Credit Rating
from S&P or Moody's, then the applicable percentage per annum shall be
determined by the lowest of the ratings.  In the event that only one (1) Rating
Agency has set the Borrower's or CESRRI's Credit Rating, or CESRRI or Borrower
does not maintain the Investment Grade Ratings, then the Facility Fee shall be
based on Borrower's Leverage Ratio as set forth above. Notwithstanding anything
herein contained to the contrary, the Borrower shall always have the right to
elect that the Facility Fee be determined based upon its Leverage Ratio by
written notice to Administrative Agent, with such election to become effective
upon the next Domestic Business Day following receipt of such notice by the
Administrative Agent.  Any change in the Facility Fee resulting from a change in
a Credit Rating shall become effective on the effective date of the change in
the applicable Credit Rating.  The Facility Fee shall be payable quarterly in
arrears on each January 1, April 1, July 1 and October 1 during the Term.  The
Facility Fee for any partial calendar quarter shall be prorated as provided in
Section 2.14.

          (b)  Letter of Credit Fee.  During the Term, the Borrower shall pay to
               --------------------

Administrative Agent, for the account of the Banks in proportion to their
interests in respective undrawn issued Letters of Credit, a fee (the "Letter of
Credit Fee") in an amount, provided that no Event of Default shall have occurred
and be continuing, equal to a rate per annum of one percent (1%) on the daily
average of the undrawn amount of such Letters of Credit, which fee shall be
payable quarterly, in arrears, on each January 1, April 1, July 1 and October 1
during the Term. From the occurrence, and during the continuance, of an Event of
Default, such fee shall be increased to be equal to four percent (4%) per annum
on the daily average of the undrawn amount of such Letters of Credit. The Letter
of Credit Fee for any partial calendar quarter shall be prorated.

          (c)  Fronting Bank Fee. The Borrower shall pay the Administrative
               -----------------                                           
Agent, for the Fronting Bank's account, a fee (the "Fronting Bank Fee") at a
rate per annum equal to one-eighth of one percent (0.125%) of the undrawn amount
of such Letter of Credit (less the Fronting Bank's pro rata share thereof based
upon the amount of the Fronting Bank's pro rata share of the Commitments), which
fee shall be in addition to and not in lieu of, the Letter of Credit Fee.  The
Fronting Bank Fee shall be payable in arrears on each January 1, April 1, July 1
and October 1 during the Term.  The Fronting Bank Fee for any partial calendar
quarter shall be prorated.

          (d)  Closing Fee.  The Borrower shall pay to the Administrative Agent
               -----------                                                     
certain closing and amendment fees pursuant to the Fee Letter. The
Administrative Agent shall pay to the Banks shares of the closing and amendment
fees in accordance with their separate agreements.

          (e)  Administrative Agent's Fee.  The Borrower shall also pay to the
               --------------------------                                     
Administrative Agent, for the Administrative Agent's own account, an
Administrative Agent's fee pursuant to the Fee Letter.

          (f)  Extension Fee.  As provided in Section 2.9(b) and (c), the
               -------------
Borrower shall pay to the Administrative Agent, for the account of the Banks in
proportion to the Commitments, an extension fee (the "Extension Fee") in the
amount of one-tenth of one percent (.10%) of the Commitments of Banks which
shall be participating in an extension of the Maturity Date, when due in
accordance with Section 2.9(b) or (c), as applicable.

          (g)  Money Market Loan Fees.  The Borrower agrees to pay the
               ----------------------                                 
Administrative Agent together with each Money Market Loan Request an
administrative fee in the amount of $1,000, or as otherwise may be agreed to in
writing from time to time.

          (h)  Fees Non-Refundable.  All fees set forth in this Section 2.8
               -------------------
shall be deemed to have been earned on the date payment is due in accordance
with the provisions hereof and shall be non-refundable. The obligation of the
Borrower to pay such fees in accordance with the provisions hereof shall be
binding upon the Borrower and shall inure to the benefit of the Administrative
Agent and the Banks regardless of whether any Loans are actually made.

     SECTION 2.9.  Maturity Date; Extension of Maturity Date.
                   ----------------------------------------- 

     (a)  The term (the "Term") of the Commitments (and each Bank's obligations
to make Loans and to participate in Letters of Credit hereunder) shall terminate
and expire and the Borrower 

                                       42
<PAGE>
 
shall return or cause there to be returned all Letters of Credit to the Fronting
Bank on the Maturity Date, unless the Term shall be extended as hereinafter set
forth. Upon the date of the termination of the Term, any Loans then outstanding
(together with accrued interest thereon and all other obligations) shall be due
and payable on such date.

     (b)  Provided that no Default or Event of Default then exists, the Borrower
may request that the Administrative Agent and the Banks extend the initial
Maturity Date for an additional  two (2) year period by executing and delivering
to the Administrative Agent at least ninety (90) days but no more than one
hundred twenty (120) days prior to the initial Maturity Date, a written request
in the form of Exhibit J (an "Extension Request"), with the joinder in the
Extension Request of each Consolidated Subsidiary which has provided a Guaranty
pursuant hereto.  The Administrative Agent shall forward to each Bank a copy of
the Extension Request delivered to the Administrative Agent promptly after
receipt thereof.  The Borrower understands that this Section has been included
in this Agreement for the Borrower's convenience in requesting an extension of
the Maturity Date and the Borrower acknowledges that none of the Banks nor the
Administrative Agent has promised (either expressly or impliedly), nor has any
obligation or commitment whatsoever, to extend the Maturity Date.  If all of the
Banks shall have notified the Administrative Agent in writing on or prior to the
date which is sixty (60) days prior to the initial Maturity Date that they
accept such Extension Request, then the Maturity Date shall be extended to the
date two (2) years following the initial Maturity Date.  If any Bank shall not
have notified the Administrative Agent on or prior to the date which is sixty
(60) days prior to the initial Maturity Date that it accepts such Extension
Request, then the Maturity Date shall not be extended.  The Administrative Agent
shall promptly notify the Borrower whether the Extension Request has been
accepted or rejected, and if rejected, the Administrative Agent shall also give
the Borrower notice of which Banks rejected such Extension Request (each such
Bank a "Rejecting Lender').  If accepted, within five (5) Domestic Business Days
after Borrower's receipt of notification thereof, Borrower shall pay the
Extension Fee to the Administrative Agent.

     (c)  Notwithstanding the preceding subsection (b), after notification from
the Administrative Agent to the Borrower that an Extension Request has been
rejected, the Maturity Date shall be extended as requested in such Extension
Request if (i) the Required Banks consented to such Extension Request, (ii) no
later than thirty (30) days prior to the initial Maturity Date, the Borrower
shall have given written notice to the Administrative Agent and each Bank that
the Borrower desires the Maturity Date to be so extended notwithstanding such
rejection,  (iii) the Borrower shall have, no later than ten (10) days prior to
the initial Maturity Date (x) caused each Rejecting Lender to have assigned its
respective Commitment to a Bank  subject to and in accordance with the
provisions of Section 9.6(c) for a purchase price equal to the aggregate
principal balance of Loans then owing to such Rejecting Lender plus any accrued
but unpaid interest thereon and accrued but unpaid fees owing to such Rejecting
Lender, and (y) to the extent the Commitment of any Rejecting Lender is not so
assigned by such date, paid to such Rejecting Lender the aggregate principal
balance of Loans then owing to such Rejecting Lender plus any accrued but unpaid
interest thereon and accrued but unpaid fees owing to such Rejecting Lender,
whereupon such Rejecting Lender's Commitment shall terminate, and such Rejecting
Lender shall no longer be a party hereto or have any rights or obligations
hereunder or under any of the other Loan Documents, and (iv) on or before the
initial Maturity Date, the Borrower shall pay the Extension Fee to the
Administrative 

                                       43
<PAGE>
 
Agent for the ratable benefit of the Banks participating in the extension to the
extent of their Commitments. In addition, in connection with any such assignment
by a Rejecting Lender or any such payment to a Rejecting Lender, the Borrower
shall pay the amounts, if any, due such Rejecting Lender under Section 2.13. If
the Borrower desires to cause any Rejecting Lender to assign its Commitment to
an existing or new Bank pursuant to this subsection, the Borrower shall so
notify such Rejecting Lender, the Administrative Agent and the other Banks in
writing no later than the date thirty (30) days prior to the initial Maturity
Date. A Rejecting Lender shall be obligated to assign its Commitment pursuant to
this subsection if requested to do so by the Borrower subject to Borrower's
compliance with the provisions of this subsection. Each Bank that is not a
Rejecting Lender shall have the right (but not the obligation) to acquire such
Rejecting Lender's Commitment and shall exercise such right by giving written
notice thereof to the Administrative Agent no later than five (5) Domestic
Business Days following receipt of the Borrower's notice. Any Bank who has
failed to so notify the Administrative Agent and the Borrower within such five
(5) Domestic Business Day period shall be deemed to have declined to exercise
such right. If more than one Bank exercises its right to acquire a Rejecting
Lender's Commitment, each such Bank shall acquire an amount of such Rejecting
Lender's Commitment in proportion to the Commitments of the Banks exercising
such right. After the expiration of such five (5) Domestic Business Day period,
the Borrower shall have the right to attempt to cause one or more new or
existing Banks to accept an assignment of a Rejecting Lender's Commitment in
accordance with, and subject to, the provisions of Section 9.6(c) hereof.
Neither the Administrative Agent nor any Bank shall have any obligation to
assist the Borrower in finding any such Bank. If the Required Banks do not
consent to the Extension Request or if the Borrower fails to comply with any
provision of this subsection, the Maturity Date shall not be extended.

      SECTION 2.10. [Intentionally Deleted].

      SECTION 2.11. Optional Prepayments.
                    -------------------- 

          (a)  The Borrower may, upon notice to the Administrative Agent
delivered by 11:00 a.m., Pittsburgh time on the preceding Domestic Business Day,
prepay any Base Rate Group of Loans (or any Euro-Dollar Borrowing bearing
interest at the Base Rate pursuant to Section 8.1), in whole at any time, or
from time to time in part in amounts aggregating One Million Dollars
($1,000,000) or any larger multiple of One Hundred Thousand Dollars ($100,000),
by paying to the Administrative Agent the principal amount to be prepaid
together with accrued interest thereon to the date of prepayment.  Each such
optional prepayment shall be applied by the Administrative Agent to prepay
ratably the Loans of the several Banks included in such Group of Loans or
Borrowing.

          (b)  The Borrower may, upon notice to the Administrative Agent
delivered by 11:00 a.m., Pittsburgh time on the preceding Euro-Dollar Business
Day, prepay any Euro-Dollar Loan as of the last day of the Interest Period
applicable thereto.  The Borrower may not prepay all or any portion of the
principal amount of any Euro-Dollar Loan prior to the end of the Interest Period
applicable thereto unless the Borrower shall also pay any applicable expenses
pursuant to Section 2.13. Any such prepayment prior to the end of the Interest
Period applicable thereto shall be upon at least three (3) Euro-Dollar Business
Days notice to the Administrative Agent.  Each such optional 

                                       44
<PAGE>
 
prepayment shall be in the amounts set forth in Section 2.11(a) above and shall
be applied to prepay ratably the Loans of the Banks included in any Euro-Dollar
Group of Loans, except that any Euro-Dollar Loan which has been converted to a
Base Rate Loan pursuant to Section 8.2, 8.3 or 8.4 hereof may be prepaid without
ratable payment of the other Loans in such Group of Loans which have not been so
converted.

          (c)  The Borrower may, upon at least one (1) Domestic Business Day's
notice to the Administrative Agent (by 11:00 a.m Pittsburgh time on such
Domestic Business Day), reimburse the Administrative Agent for the benefit of
the Fronting Bank for the amount of any drawing under a Letter of Credit in
whole or in part in any amount.

          (d)  The Borrower may at any time return any undrawn Letter of Credit
to the Fronting Bank in whole, but not in part, and the Fronting Bank within one
(1) Domestic Business Day shall give the Administrative Agent and each of the
Banks notice of such return.

          (e)  The Borrower may at any time and from time to time cancel all or
any part of the Commitments by the delivery to the Administrative Agent of a
notice of cancellation within the applicable time periods for prepayments set
forth in Sections 2.11(a) and (b) if there are Loans then outstanding or, if
there are no Loans outstanding at such time as to which the Commitments with
respect thereto are being canceled, upon at least one (1) Domestic Business
Day's notice to the Administrative Agent, whereupon, in either event, all or
such portion of the Commitments, as applicable, shall terminate as to the Banks,
pro rata on the date set forth in such notice of cancellation, and, if there are
any Loans then outstanding, Borrower shall prepay, as applicable, all or such
portion of Loans outstanding on such date in accordance with the requirements of
Section 2.11(a) and (b).  In no event shall the Borrower be permitted to cancel
Commitments for which a Letter of Credit has been issued and is outstanding
unless the Borrower returns (or causes to be returned) such Letter of Credit to
the Fronting Bank.  Borrower shall be permitted to designate in its notice of
cancellation which Loans, if any, are to be prepaid.

          (f)  Any amounts so prepaid pursuant to Section 2.11 (a) or (b) may be
reborrowed.  In the event Borrower elects to cancel all or any portion of the
Commitments pursuant to Section 2.11(c) hereof, such amounts may not be
reborrowed.

          (g)  Notwithstanding anything herein contained to the contrary, the
Borrower may not prepay all or any portion of the principal amount of any Money
Market Loan prior to the end of the Interest Period applicable thereto.

      SECTION 2.12. General Provisions as to Payments.
                    --------------------------------- 

          (a)  The Borrower shall make each payment of the principal and
interest on the Loans and of fees hereunder, not later than 12:00 Noon
Pittsburgh time on the date when due, in Federal or other funds immediately
available in Pittsburgh, to the Administrative Agent at its address referred to
in Section 9.1. If any such payment is received by the Administrative Agent
later than 12:00 Noon Pittsburgh time, such payment shall be treated as having
been made on the next Domestic Business Day or Euro-Dollar Business Day, as
applicable. The Administrative Agent will

                                       45
<PAGE>
 
promptly distribute to each Bank its ratable share (or applicable share with
respect to Money Market Loans) of each such payment received by the
Administrative Agent for the account of the Banks. If and to the extent that the
Administrative Agent shall receive any such payment for the account of the Banks
on or before 12:00 Noon Pittsburgh time on any Domestic Business Day, and
Administrative Agent shall not have distributed to any Bank its applicable share
of such payment on such Domestic Business Day, Administrative Agent shall
distribute such amount to such Bank together with interest thereon, for each day
from the date such amount should have been distributed to such Bank until the
date Administrative Agent distributes such amount to such Bank, at the Federal
Funds Rate. Whenever any payment of principal of, or interest on the Base Rate
Loans or of fees shall be due on a day which is not a Domestic Business Day, the
date for payment thereof shall be extended to the next succeeding Domestic
Business Day. Whenever any payment of principal of, or interest on, the Euro-
Dollar Loans shall be due on a day which is not a Euro-Dollar Business Day, the
date for payment thereof shall be extended to the next succeeding Euro-Dollar
Business Day unless such Euro-Dollar Business Day falls in another calendar
month, in which case the date for payment thereof shall be the next preceding
Euro-Dollar Business Day. Whenever any payment of principal of, or interest on,
the Money Market Loans shall be due on a day which is not a Euro-Dollar Business
Day, the date for payment thereof shall be extended to the next succeeding Euro-
Dollar Business Day. If the date for any payment of principal is extended by
operation of law or otherwise, interest thereon shall be payable for such
extended time. Unless the Borrower shall otherwise instruct the Administrative
Agent, each payment of principal made by Borrower hereunder shall be first
applied to reduce amounts allocated to the Working Capital Sublimit to the
extent that advances have been so allocated.

          (b)  Unless the Administrative Agent shall have received notice from
the Borrower prior to the date on which any payment is due to the Banks
hereunder that the Borrower will not make such payment in full, the
Administrative Agent may assume that the Borrower has made such payment in full
to the Administrative Agent on such date and the Administrative Agent may, in
reliance upon such assumption, cause to be distributed to each Bank on such due
date an amount equal to the amount then due such Bank. If and to the extent that
the Borrower shall not have so made such payment, each Bank shall repay to the
Administrative Agent forthwith on demand such amount distributed to such Bank
together with interest thereon, for each day from the date such amount is
distributed to such Bank until the date such Bank repays such amount to the
Administrative Agent, at the Federal Funds Rate.

     SECTION 2.13.  Funding Losses.
                    -------------- 

     If the Borrower makes any payment of principal with respect to any Euro-
Dollar Loan (pursuant to Article II, VI or VIII or otherwise) on any day other
than the last day of the Interest Period applicable thereto, or if the Borrower
fails to borrow any Euro-Dollar Loans after notice has been given by the
Administrative Agent to any Bank in accordance with Section 2.4(a), or if
Borrower shall deliver a Notice of Interest Rate Election specifying that a
Euro-Dollar Loan shall be converted on a date other than the last day of' the
then current Interest Period applicable thereto, the Borrower shall reimburse
each Bank within fifteen (15) days after Borrower receives certification of such
Bank of such loss or expense (which shall be delivered by each such Bank to
Administrative Agent for delivery to Borrower) for any resulting loss or expense
incurred by it (or by an existing 

                                       46
<PAGE>
 
Participant in the related Loan), including (without limitation) any loss
incurred in obtaining, liquidating or employing deposits from third parties, but
excluding loss of margin for the period after any such payment or failure to
borrow, provided that such Bank shall have delivered to Administrative Agent and
Administrative Agent shall have delivered to the Borrower a certification as to
the amount of such loss or expense, which certification shall set forth in
reasonable detail the basis for and calculation of such loss or expense and
shall be conclusive in the absence of demonstrable error. Calculation of all
amounts payable to a Bank under this Section 2.13 shall be made as though such
Bank had actually funded Euro-Dollar Loans through the purchase of deposits in
the relevant market bearing interest at the rate applicable to such Euro-Dollar
Loans in an amount equal to the amount of the Euro-Dollar Loans and having a
maturity comparable to the relevant Interest Period, provided, however, that
each Bank may fund each of its Euro-Dollar Loans in any manner it sees fit and
the foregoing assumption shall be used only for calculation of amounts payable
under this Section 2.13.

     SECTION 2.14. Computation of Interest and Fees.
                   -------------------------------- 

     All interest and fees (other than the closing fee and amendment fee
pursuant to Section 2.8(d) and the Extension Fee) shall be computed on the basis
of a year of 360 days and paid for the actual number of days elapsed (including
the first day but excluding the last day), provided that the Facility Fee shall
be computed on a quarterly basis, with any partial quarter being prorated on a
per diem basis using the total number of days in the applicable calendar
quarter.

     SECTION 2.15. Use of Proceeds.
                   --------------- 

     Borrower shall use the proceeds of the Loans only for pre-development
costs, development costs, construction costs, acquisitions, working capital,
equity investments and repayment of Indebtedness . Use of proceeds for working
capital purposes shall not exceed Fifty Million Dollars ($50,000,000.00) at any
one time (the "Working Capital Sublimit").

     SECTION 2.16. Letters of Credit.
                   ----------------- 

          (a)  Subject to the terms contained in this Agreement and the other
Loan Documents, upon the receipt of a notice in accordance with Section 2.2(b)
requesting the issuance of a Letter of Credit, the Fronting Bank shall issue a
Letter of Credit or Letters of Credit in such form as is reasonably acceptable
to the Borrower subject to the provisions of Section 2.2(b) in an amount or
amounts equal to the amount or amounts requested by the Borrower.

          (b)  Each Letter of Credit shall be issued in the minimum amount of
One Hundred Thousand Dollars ($100,000).

          (c)  The Letter of Credit Usage shall be no more than Twenty-Five
Million Dollars ($25,000,000) at any one time.

          (d)  There shall be no more than ten (10) Letters of Credit
outstanding at any one time.

                                       47
<PAGE>
 
          (e)  In the event of any request for a drawing under any Letter of
Credit by the beneficiary thereunder, the Fronting Bank shall notify the
Borrower and the Administrative Agent (and the Administrative Agent shall notify
each Bank thereof) on or before the date on which the Fronting Bank intends to
honor such drawing, and, except as provided in this subsection (e), the Borrower
shall reimburse the Fronting Bank, in immediately available funds, on the same
day on which such drawing is honored in an amount equal to the amount of such
drawing.  Notwithstanding anything contained herein to the contrary, however,
unless the Borrower shall have notified the Administrative Agent, and the
Fronting Bank prior to 11:00 a.m. Pittsburgh time on the Domestic Business Day
immediately prior to the date of such drawing that the Borrower intends to
reimburse the Fronting Bank for the amount of such drawing with funds other than
the proceeds of the Loans, the Borrower shall be deemed to have timely given a
Notice of Borrowing pursuant to Section 2.2 to the Administrative Agent,
requesting a Borrowing of Base Rate Loans on the date on which such drawing is
honored and in an amount equal to the amount of such drawing.  Each Bank (other
than the Fronting Bank) shall, in accordance with Section 2.4 (b), make
available its pro rata share of such Borrowing to the Administrative Agent, the
proceeds of which shall be applied directly by the Administrative Agent to
reimburse the Fronting Bank for the amount of such draw.  In the event that any
such Bank fails to make available to the Fronting Bank the amount of such Bank's
pro rata share on the date of a drawing, the Fronting Bank shall be entitled to
recover such amount on demand from such Bank together with interest at the
Federal Funds Rate commencing on the date such drawing is honored, and the
provisions of Section 9.16 shall otherwise apply to such failure.

          (f)  If after the date hereof, any change in any law or regulation or
in the interpretation thereof by any court or administrative or governmental
authority charged with the administration thereof shall either (i) impose,
modify or deem applicable any reserve, special deposit or similar requirement
against letters of credit issued by, or assets held by, or deposits in or for
the account of, or participations in any letter of credit, upon any Bank
(including the Fronting Bank) or (ii) impose on any Bank any other condition
regarding this Agreement or such Bank (including the Fronting Bank) as it
pertains to the Letters of Credit or any participation therein and the result of
any event referred to in the preceding clause (i) or (ii) shall be to increase
by an amount deemed by the Fronting Bank or such Bank to be material, the cost
to the Fronting Bank or any Bank of issuing or maintaining any Letter of Credit
or participating therein, then the Borrower shall pay to the Fronting Bank or
such Bank, within fifteen (15) days after written demand by such Bank (with a
copy to the Administrative Agent) , which demand shall be accompanied by a
certificate showing, in reasonable detail, the calculation of such amount or
amounts, such additional amounts as shall be required to compensate the Fronting
Bank or such Bank for such increased costs or reduction in amounts received or
receivable hereunder.  Each Bank will promptly notify the Borrower and the
Administrative Agent of any event of which it has knowledge, occurring after the
date hereof, which will entitle such Bank to compensation pursuant to this
Section 2.16 and will designate a different Applicable Lending Office if such
designation will avoid the need for, or reduce the amount of, such compensation
and will not, in the reasonable judgment of such Bank, be otherwise
disadvantageous to such Bank.  A certificate of any Bank claiming compensation
under this Section 2.16 and setting forth a reasonably detailed calculation of
the additional amount or amounts to be paid to it hereunder shall be conclusive
in the absence of demonstrable error.  In determining such amount, such Bank may
use any reasonable averaging and attribution methods.

                                       48

          (g)  The Borrower hereby agrees to protect, indemnify, pay and save
the Fronting Bank harmless from and against any and all claims, demands,
liabilities, damages, losses, costs, charges and expenses (including reasonable
attorneys' fees and disbursements) which the Fronting Bank may incur or be
subject to as a result of (i) the issuance of the Letters of Credit, other than
to the extent of the bad faith, gross negligence or wilful misconduct of the
Fronting Bank or (ii) the failure of the Fronting Bank to honor a drawing under
any Letter of Credit as a result of any act or omission, whether rightful or
wrongful, of any present or future de jure or de facto government or
Governmental Authority (collectively, "Governmental Acts"), other than to the
extent of the bad faith, gross negligence or wilful misconduct of the Fronting
Bank.  As between the Borrower and the Fronting Bank, the Borrower assumes all
risks of the acts and omissions of any beneficiary with respect to its use, or
misuse of, the Letters of Credit issued by the Fronting Bank.  In furtherance
and not in limitation of the foregoing, the Fronting Bank shall not be
responsible (i) for the form, validity, sufficiency, accuracy, genuineness or
legal effect of any document submitted by any party in connection with the
application for and issuance of such Letters of Credit, even if it should in
fact prove to be in any or all respects invalid, insufficient, inaccurate,
fraudulent or forged; (ii) for the validity or insufficiency of any instrument
transferring or assigning or purporting to transfer or assign any such Letter of
Credit or the rights or benefits thereunder or proceeds thereof, in whole or in
part, which may prove to be invalid or ineffective for any reason; (iii) for
failure of the beneficiary of any such Letter of Credit to comply fully with
conditions required in order to draw upon such Letter of Credit, other than as a
result of the bad faith, gross negligence or wilful misconduct of the Fronting
Bank; (iv) for errors, omissions, interruptions or delays in transmission or
delivery of any message, by mail, cable, telegraph, telex, facsimile
transmission, or otherwise, unless the result of the bad faith, gross negligence
or wilful misconduct of the Fronting Bank; (v) for errors in interpretation of
any technical terms, unless the result of the bad faith, gross negligence or
wilful misconduct of the Fronting Bank; (vi) for any loss or delay in the
transmission or otherwise of any documents required in order to make a drawing
under any such Letter of Credit or of the proceeds thereof; (vii) for the
misapplication by the beneficiary of any such Letter of Credit of the proceeds
of such Letter of Credit; and (viii) for any consequence arising from causes
beyond the control of the Fronting Bank, including any Government Acts, in each
case other than to the extent of the bad faith, gross negligence or willful
misconduct of the Fronting Bank.  None of the above shall affect, impair or
prevent the vesting of the Fronting Bank's rights and powers hereunder.  In
furtherance and not in limitation of the specific provisions hereinabove set
forth, any action taken or omitted by the Fronting Bank  under or in connection
with the Letters of Credit issued by it or the related certificates, if taken or
omitted in good faith, shall not put the Fronting Bank under any resulting
liability to the Borrower; provided that, notwithstanding anything in the
foregoing to the contrary, the Fronting Bank will be liable to the Borrower for
any damages suffered by the Borrower or its Subsidiaries as a result of the
Fronting Bank's grossly negligent or wilful failure to pay under any Letter of
Credit after the presentation to it of a sight draft and certificates strictly
in compliance with the terms and conditions of the Letter of Credit.

          (h)  If the Fronting Bank or the Administrative Agent is required at
any time, pursuant to any bankruptcy, insolvency, liquidation or reorganization
law or otherwise, to return to the Borrower any reimbursement by the Borrower of
any drawing under any Letter of Credit, each Bank shall pay to the Fronting Bank
or the Administrative Agent, as the case may be, its pro rata share of such
payment, but without interest thereon unless the Fronting Bank or the
Administrative

                                       49
<PAGE>
 
Agent is required to pay interest on such amounts to the person recovering such
payment, in which case with interest thereon, computed at the same rate, and on
the same basis, as the interest that the Fronting Bank or the Administrative
Agent is required to pay.

          (i)  The Letters of Credit issued under the Existing Credit Agreement
described on Schedule 2.16 shall be deemed to be Letters of Credit issued under
this Agreement.

     SECTION 2.17. Letter of Credit Usage.
                   ---------------------- 

     The obligations of the Borrower under this Agreement in respect of any
Letter of Credit shall be unconditional and irrevocable, and shall be paid
strictly in accordance with the terms of this Agreement (as the same may be
amended from time to time) and any Letter of Credit Documents (as hereinafter
defined) under all circumstances, including, without limitation, to the extent
permitted by law, the following circumstances:

any other agreement or instrument relating thereto (collectively, the "Letter of
Credit Documents") or any Loan Document;

          (b)  any change in the time, manner or place of payment of, or in any
other term of, all or any of the obligations of the Borrower in respect of the
Letters of Credit or any other amendment or waiver of or any consent by the
Borrower to departure from all or any of the Letter of Credit Documents or any
Loan Document; provided, that the Fronting Bank shall not consent to any such
change or amendment unless previously consented to in writing by the Borrower;

          (c)  any exchange, release or non-perfection of any collateral, or any
release or amendment or waiver of or consent to departure from any guaranty, for

Credit;

the Borrower may have at any time against any beneficiary or any transferee of a
Letter of Credit (or any Persons for whom any such beneficiary or any such
transferee may be acting), the Administrative Agent, the Fronting Bank or any
Bank (other than a defense based on the bad faith, gross negligence or wilful
misconduct of the Administrative Agent, the Fronting Bank or such Bank) or any
other Person, whether in connection with the Loan Documents, the transactions
contemplated hereby or by the Letters of Credit Documents or any unrelated
transaction;

          (e)  any draft or any other document presented under or in connection
with any Letter of Credit or other Loan Document proving to be forged,
fraudulent, invalid or insufficient in any respect or any statement therein
being untrue or inaccurate in any respect; provided, that payment by the
Fronting Bank under such Letter of Credit against presentation of such draft or
document shall not have been the result of the bad faith, gross negligence or
wilful misconduct of the Fronting Bank;

          (f)  payment by the Fronting Bank against presentation of a draft or
certificate that 

                                       50
<PAGE>
 
does not strictly comply with the terms of the Letter of Credit; provided, that
such payment shall not have been the result of the bad faith, gross negligence
or wilful misconduct of the Fronting Bank; and

          (g)  any other circumstance or happening whatsoever other than the
payment in full of all obligations hereunder in respect of any Letter of Credit
or any agreement or instrument relating to any Letter of Credit, whether or not
similar to any of the foregoing, that might otherwise constitute a defense
available to, or a discharge of, the Borrower; provided, that such other
circumstance or happening shall not have been the result of bad faith, gross
negligence or wilful misconduct of the Fronting Bank.

     SECTION 4.1. Existence and Power.
                  ------------------- 

     The Borrower is a limited partnership, duly formed and validly existing as
a limited partnership under the laws of the State of Delaware and has all powers
and all material governmental licenses, authorizations, consents and approvals
required to own its property and assets and carry on its business as now
conducted or as it presently proposes to conduct and has been duly qualified and
is in good standing in every jurisdiction in which the failure to be so
qualified and/or in good standing is likely to have a Material Adverse Effect.
CESRRI is a real estate investment trust or corporation, duly formed, validly
existing and in good standing as a real estate investment trust or a corporation
under the laws of the jurisdiction in which it is organized and has all powers
and all material governmental licenses, authorizations, consents and approvals
required to own its property and assets and carry on its business as now
conducted or as it presently proposes to conduct and has been duly qualified and
is in good standing in every jurisdiction in which the failure to be so
qualified and/or in good standing is likely to have a Material Adverse Effect.

     SECTION 4.2. Power and Authority.
                  ------------------- 
 
     The Borrower has the partnership power and authority to execute, deliver
and carry out the terms and provisions of each of the Loan Documents to which it
is a party and has taken all necessary partnership action, if any, to authorize
the execution and delivery on behalf of the Borrower and the performance by the
Borrower of such Loan Documents.  The Borrower has duly executed and delivered
each Loan Document to which it is a party in accordance with the terms of this
Agreement, and each such Loan Document constitutes the legal, valid and binding
obligation of the Borrower, enforceable in accordance with its terms, except as
enforceability may be limited by applicable insolvency, bankruptcy or other laws
affecting creditors rights generally, or general principles of equity, whether
such enforceability is considered in a proceeding in equity or at law.  CESRRI
has the power and authority, as general partner of the Borrower, to execute,
deliver and 

                                       54
<PAGE>
 
carry out the terms and provisions of each of the Loan Documents on behalf of
the Borrower to which the Borrower is a party and has taken all necessary action
to authorize, as general partner of the Borrower, the execution and delivery on
behalf of the Borrower and the performance by the Borrower of such Loan
Documents. The Borrower has obtained all consents and authorizations required
pursuant to the terms of any indenture, mortgage, deed of trust or other
material agreement to which it or any of its Consolidated Subsidiaries is a
party as may be necessary to allow Borrower and the Consolidated Subsidiaries to
lawfully execute, deliver and perform their obligations under the Loan Documents
to which they are parties.

     SECTION 4.3. No Violation.
                  ------------ 

     Neither the execution, delivery or performance by or on behalf of the
Borrower of the Loan Documents to which it is a party, nor compliance by the
Borrower with the terms and provisions thereof nor the consummation of the
transactions contemplated by the Loan Documents, (i) will materially contravene
any applicable provision of any law, statute, rule, regulation, order, writ,
injunction or decree of any court or governmental instrumentality, (ii) will
materially conflict with or result in any breach of, any of the terms,
covenants, conditions or provisions of, or constitute a default under, or result
in the creation or imposition of (or the obligation to create or impose) any
Lien upon any of the property or assets of the Borrower or any of its
Consolidated Subsidiaries pursuant to the terms of any indenture, mortgage, deed
of trust, or other agreement or other instrument to which the Borrower (or of
any partnership of which the Borrower is a partner) or any of its Consolidated
Subsidiaries is a party or by which it or any of its property or assets is bound
or to which it is subject, or (iii) will cause a material default by the
Borrower under any organizational document of any person in which the Borrower
has an interest, or cause a material default under the Borrower's agreement or
certificate of limited partnership, the consequences of which conflict, breach
or default would have a Material Adverse Effect, or result in or require the
creation or imposition of any material Lien whatsoever upon any Property (except
as contemplated herein).

     SECTION 4.4. Financial Information.
                  ---------------------

the calculation thereof in the last Compliance Certificate submitted prior
thereto reflecting the amount of the additional Borrowing and any other

      SECTION 5.9.  Restriction on Fundamental Changes.
                    ---------------------------------- 

          (a) Neither the Borrower nor CESRRI shall enter into any merger or

Neither the Borrower nor CESRRI shall liquidate, wind-up or dissolve (or suffer
any liquidation or dissolution), discontinue its business or convey, lease,
sell, transfer or otherwise dispose of, in one transaction or series of
transactions, all or substantially all of its business or property, whether now

prohibit the sale or leasing of portions of the Real Property Assets in the
ordinary course of business.

          (b) The Borrower shall not amend its agreement of limited partnership
or other organizational documents in any  manner that would be materially
adverse to the Banks without the Administrative Agent's consent, which shall not
be unreasonably withheld.  CESRRI shall not amend its articles of incorporation,
by-laws, or other organizational documents in any  manner that would be
materially adverse to the Banks without the Administrative Agent's consent,

Maturity Date), (ii) shall have the effect of capping the interest rates covered
thereby at a rate equal to or lower than the Hedge Rate at the time of purchase
or execution, and (iii) shall be with the Administrative Agent or an Approved

      SECTION 5.14. Acceptance of Qualifying Unencumbered Properties
                    ------------------------------------------------

     (a)  The Banks have accepted the Properties listed on Exhibit F as of the
Effective Date as Qualifying Unencumbered Properties.  If the Borrower desires
to add a  Property as a Qualifying Unencumbered Property, the Borrower shall so
notify the Administrative Agent in writing.  To the extent that increased Loan
Availability is necessary in order for a Borrowing to be permitted, such
notification shall be delivered to the Administrative Agent at least five (5)
Domestic Business Days prior to the submission of the applicable Notice of
Borrowing or Money Market Loan Request.  The Property will be accepted as a
Qualifying Unencumbered Property when the Borrower delivers to the
Administrative Agent a certificate that the Property is a Qualifying
Unencumbered Property in the form attached hereto as Exhibit K, as well as the
following in form and substance satisfactory to the Administrative Agent:

          (i)    with respect to any Property being acquired by Borrower or a
     Consolidated Subsidiary, a copy of the relevant materials relating to such
     Property submitted by the Borrower to its board of directors, executive
     committee or investment committee, as applicable for their approval, or
     such other materials as Borrower deems relevant, as well as a copy of the
     environmental report and, if applicable, any ground lease affecting such
     Property;

          (ii)   if required under Section 2.3 or 2.4(a), or if the Borrower
     otherwise so elects, an updated Compliance Certificate as described in
     Section 5.8(l); and

          (iii)  if such Property is owned or leased by a Consolidated
     Subsidiary, a Guaranty and all of the documents required to be provided
     under Section 3.1, with respect to a Guaranty to be furnished by a
     Consolidated Subsidiary, if not previously delivered to the Administrative
     Agent, and, if such Property is subject to a Lien permitted under
     subsection h of the definition of Permitted Liens, a Guaranty and the
     Security Documents from the Consolidated Subsidiary which owns such Lien,
     and all of the documents required to be provided under Section 3.1 with
     respect to a Guaranty to be furnished by a Consolidated Subsidiary.

     Following receipt of the foregoing certificate documents and information,
the Administrative Agent shall review them as expeditiously as is reasonably
practicable under the circumstances but in any event within five (5) Domestic
Business Days of receipt of all such documents and information. If, following
such review, the Administrative Agent has confirmed that such Property
constitutes a 

                                       68
<PAGE>
 
Qualifying Unencumbered Property, the Administrative Agent will promptly send
copies of the applicable certificate concerning Qualifying Unencumbered Property
status and the related property information and, if applicable, copies of the
Compliance Certificate updating the calculation of the covenants contained in
Section 5.8(e) and (i), the Guaranty and the Security Documents, to the Banks.
If, following such review, the Administrative Agent determines that such
Property does not constitute a Qualifying Unencumbered Property or that
Administrative Agent does not have sufficient information or documents to
determine whether the Property constitutes a Qualifying Unencumbered Property ,
the Administrative Agent will promptly so notify the Borrower that the Property
shall not be deemed to be a Qualifying Unencumbered Property.

     (b) If, following a determination by the Administrative Agent that a
Property does not constitute a Qualifying Unencumbered Property, the Borrower
shall so request that the Administrative Agent submit such Property to the Banks
for the approval by the Required Banks, the Administrative Agent will submit
such documents and information to the other Banks for their review.  The
Borrower also shall have the right, while acknowledging that a Property does not
meet the standards of a Qualifying Unencumbered Property, to submit the
applicable documents and information described in subparagraph (a) above to the
Administrative Agent and the Banks, and request that such Property nevertheless
be accepted by the Required Banks as a Qualifying Unencumbered Property.  Each
Bank shall notify the Administrative Agent whether it approves or rejects of the
designation of such Property as a Qualifying Unencumbered Property within ten
(10) Domestic Business Days of receipt of  such documents and information.  If a
Bank shall fail to so notify the Administrative Agent, then such Bank shall be
deemed to have accepted such Property.  If, following such review, the Property
is approved by the Required Banks, such Property shall immediately become a
Qualifying Unencumbered Property. If, following such review, the Property is
rejected by the Required Banks, the Administrative Agent will promptly so notify
the Borrower.

 
     (c) From time to time the Borrower may elect that a Property cease to be a
Qualifying Unencumbered Property.  Such election shall be in writing and shall
be effective upon delivery to the Administrative Agent, provided that, if the
ceasing of such Property to constitute a Qualifying Unencumbered Property shall
result in a reduction in Loan Availability or result in a violation of any other
limitation affecting the Qualifying Unencumbered Properties, such election shall
be delivered to the Administrative Agent five (5) Domestic Business Days before
such election shall become effective. Such election shall become effective on
such fifth Domestic Business Day so long as:

         (i)   no Default or Event of Default shall have occurred and be
     continuing both at the time of such election and immediately after giving
     effect to such election; and

         (ii)  the Borrower shall have delivered to the Administrative Agent an
     updated Compliance Certificate with such election in accordance with
     Section 5.8(l) demonstrating on a pro forma basis that the Borrower will
     remain in compliance with Section 2.1 and 5.8 (e) and (i) hereof after
     giving effect to such request and any prepayment to be made and/or the
     acceptance of any Property as an additional or replacement Qualifying
     Unencumbered Property to be given concurrently with such request, and the
     Administrative Agent shall have reviewed and accepted such updated
     Compliance Certificate.

                                       69

     (d) A Property shall cease to be included in the calculation of
Unencumbered Asset Value if it shall cease to be a Qualifying Unencumbered
Property.

      SECTION 5.15. Payment of Taxes and Claims.
                    --------------------------- 

     Borrower shall pay (i) all taxes, assessments and other governmental
charges imposed upon it or on any of its properties or assets or in respect of
any of its franchises, business, income or property before any penalty or
interest accrues thereon, the failure to make payment of which will have a
Material Adverse Effect on Borrower, and (ii) all claims (including, without
limitation, claims for labor, services, materials and supplies) for sums,
material in the aggregate to Borrow-er, which have become due and payable and
which by law have or may become a Lien other than a judgment lien upon any of
Borrower's properties or assets, prior to the time when any penalty or fine
shall be incurred with respect thereto.

      SECTION 5.16. Maintenance of Permits, Etc.
                    ----------------------------

     Borrower will maintain in full force and effect all Permits, franchises,
patents, trademarks, trade names, copyrights, authorizations or other rights
necessary for the operation of its business, except where the failure to obtain
any of the foregoing would not have a Material Adverse Effect on Borrower; and
notify Administrative Agent in writing, promptly after learning thereof, of the
suspension, cancellation, revocation or discontinuance of or of any pending or
threatened action or proceeding seeking to suspend, cancel, revoke or
discontinue any material Permit, patent, trademark, trade name, copyright,
governmental approval, franchise, authorization or right, except where such
suspension, cancellation, revocation or discontinuance would not have a Material
Adverse Effect.

      SECTION 5.17. Disposal of Consolidated Subsidiary Interests.
                    --------------------------------------------- 

     Neither Borrower nor CESRRI will directly or indirectly convey, sell,
transfer, assign, pledge or otherwise encumber or dispose of any of its
partnership or membership interests, whether owned directly or indirectly
through other Persons, in any Consolidated Subsidiary at any time when such
Consolidated Subsidiary owns a Qualifying Unencumbered Property, unless, after
giving effect to such transaction, there is no Default or Event of Default
hereunder, including, without limitation, a breach of Section 5.8 hereof.  Upon
any such sale, transfer, assignment, pledge, encumbrance or disposal in
accordance with this Section 5.17, each Qualifying Unencumbered Property owned
by the applicable Consolidated Subsidiary shall cease to be a Qualifying
Unencumbered Property.  Borrower shall provide the Administrative Agent with an
updated Compliance Certificate pursuant to Section 5.8(1) demonstrating
Borrower's continued compliance prior to the consummation of any such
transaction.

      SECTION 5.18. Environmental Liabilities.
                    ------------------------- 

     Neither Borrower nor any of its Subsidiaries shall become subject to any
Environmental 

                                       70
<PAGE>
 
Claim which has a Material Adverse Effect, including any arising out of or
related to (i) the release or threatened release of any Material of
Environmental Concern into the environment, or any remedial action in response
thereto, or (ii) any violation of any Environmental Laws. Notwithstanding the
foregoing provision, the Borrower shall have the right to contest in good faith
any claim of violation of an Environmental Law by appropriate legal proceedings
and shall be entitled to postpone compliance with the obligation being contested
as long as (i) no Event of Default shall have occurred and be continuing, (ii)
the Borrower shall have given Administrative Agent prior written notice of the
commencement of such contest, (iii) noncompliance with such Environmental Law
shall not subject the Borrower or such Subsidiary to any criminal penalty or
subject Administrative Agent, or any Bank to pay any civil penalty or to
prosecution for a crime, and (iv) no portion of any Property material to
Borrower or its condition or prospects shall be in substantial danger of being
sold, forfeited or lost, by reason of such contest or the continued existence of
the matter being contested.

6.1) for  thirty (30) days after written notice thereof has been given to the
Borrower by the Administrative Agent, or, if such default is of such a nature
that it cannot with reasonable effort be completely remedied within said period
of thirty (30) days, such additional period of time as may be reasonably
necessary to cure same, provided Borrower commences such cure within said thirty
(30) day period and diligently prosecutes same, until completion, but in no

Code that could reasonably be expected to be imposed on any member of the ERISA
Group or their assets in respect of such failure shall be equal to or greater
than Ten Million Dollars ($10,000,000) and which the Administrative Agent
reasonably determines will have a Material Adverse Effect;

          (n) at any time, for any reason the Borrower seeks to repudiate its
obligations under any Loan Document; or

          (o) a default beyond any applicable notice or grace period under any
of the other Loan Documents, including, without limitation, under any of the
Guaranties.

      SECTION 6.2.  Rights and Remedies.
                    ------------------- 

          (a) Upon the occurrence of any Event of Default described in Sections
6.1(f) or (g), the Commitments shall immediately terminate and the unpaid
principal amount of, and any and all accrued interest on, the Loans and any and
all accrued fees and other obligations hereunder shall automatically become
immediately due and payable, with all additional interest from time to time
accrued thereon and without presentation, demand, or protest or other
requirements of any kind (including, without limitation, valuation and
appraisement, diligence, presentment, notice of intent to demand or accelerate
and notice of acceleration), all of which are hereby expressly waived by the
Borrower; and upon the occurrence and during the continuance of any other Event
of Default, the Administrative Agent may (and upon the demand of the Required
Banks shall), by written notice to the Borrower, in addition to the exercise of
all of the rights and remedies permitted the Administrative 

                                       73
<PAGE>
 
Agent and the Banks at law or equity or under any of the other Loan Documents,
declare the Commitments terminated and the unpaid principal amount of and any
and all accrued and unpaid interest on the Loans and any and all accrued fees
and other obligations hereunder to be, and the same shall thereupon be,
immediately due and payable with all additional interest from time to time
accrued thereon and (except as otherwise provided in the Loan Documents) without
presentation, demand, or protest or other requirements of any kind (including,
without limitation, valuation and appraisement, diligence, presentment, notice
of intent to demand or accelerate and notice of acceleration), all of which are
hereby expressly waived by the Borrower.

          (b) Notwithstanding anything to the contrary contained in this
Agreement or in any other Loan Document, the Administrative Agent, and the Banks
each agree that any exercise or enforcement of the rights and remedies granted
to the Administrative Agent or the Banks or the Fronting Bank under this
Agreement or at law or in equity with respect to this Agreement or any other
Loan Documents shall be commenced and maintained by the Administrative Agent on
behalf of the Administrative Agent and/or the Banks and/or the Fronting Bank.
The Administrative Agent shall act at the direction of the Required Banks in
connection with the exercise of any and all remedies at law, in equity or under
any of the Loan Documents or, if the Required Banks are unable to reach
agreement, then, from and after an Event of Default, the Administrative Agent
may pursue such rights and remedies as it may determine.

      SECTION 6.3.  Notice of Default.
                    ----------------- 

     The Administrative Agent shall give notice to the Borrower under Section
6.1(c) promptly upon being requested to do so by the Required Banks and shall
thereupon notify all the Banks thereof. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default (other than nonpayment of principal of or interest on the Loans) unless
Administrative Agent has received notice in writing from a Bank or Borrower
referring to this Agreement or the other Loan Documents, describing such event
or condition.  Should Administrative Agent receive notice of the occurrence of a
Default or Event of Default expressly stating that such notice is a notice of  a
Default or Event of Default, or should Administrative Agent send Borrower a
notice of Default or Event of Default, Administrative Agent shall promptly give
notice thereof to each Bank.

      SECTION 6.4.  Actions in Respect of Letters of Credit.
                    --------------------------------------- 

          (a) If, at any time and from time to time, any Letter of Credit shall
have been issued hereunder and an Event of Default shall have occurred and be
continuing, then, upon the occurrence and during the continuation thereof, the
Administrative Agent may, and upon the demand of the Required Banks shall,
whether in addition to the taking by the Administrative Agent of any of the
actions described in this Article VI or otherwise, make a demand upon the
Borrower to, and forthwith upon such demand (but in any event within ten (10)
days after such demand) the Borrower shall pay to the Administrative Agent, on
behalf of the Banks, in same day funds at the Administrative Agent's office
designated in such demand, for deposit in a special cash collateral account (the
"Letter of Credit Collateral Account") to be maintained in the name of the
Administrative Agent (on behalf of the Banks) and under its sole dominion and
control at such place 

                                       74
<PAGE>
 
as shall be designated by the Administrative Agent, an amount equal to the
amount of the Letter of Credit Usage under the Letters of Credit. Interest shall
accrue on the Letter of Credit Collateral Account at a rate equal to the rate on
overnight funds.

          (b)  The Borrower hereby pledges, assigns and grants to the
Administrative Agent, as administrative agent for its benefit and the ratable
benefit of the Banks a lien on and a security interest in, the following
collateral (the "Letter of Credit Collateral"):

               (i)    the Letter of Credit Collateral Account, all cash
deposited therein and all certificates and instruments, if any, from time to
time representing or evidencing the Letter of Credit Collateral Account;

               (ii)   all notes, certificates of deposit and other instruments
from time to time hereafter delivered to or otherwise possessed by the
Administrative Agent for or on behalf of the Borrower in substitution for or in
respect of any or all of the then existing Letter of Credit Collateral;

               (iii)  all interest, dividends, cash, instruments and other
Property from time to time received, receivable or otherwise distributed in
respect of or in exchange for any or all of the then existing Letter of Credit
Collateral; and

               (iv)   to the extent not covered by the above clauses, all
proceeds of any or all of the foregoing Letter of Credit Collateral.

The lien and security interest granted hereby secures the payment of all
obligations of the Borrower now or hereafter existing hereunder and under any
other Loan Document.

          (c)  The Borrower hereby authorizes the Administrative Agent for the
ratable benefit of the Banks to apply, from time to time after funds are
deposited in the Letter of Credit Collateral Account, funds then held in the
Letter of Credit Collateral Account to the payment of any amounts, in such order
as the Administrative Agent may elect, as shall have become due and payable by
the Borrower to the Banks in respect of the Letters of Credit.

          (d)  Neither the Borrower nor any Person claiming or acting on behalf
of or through the Borrower shall have any right to withdraw any of the funds
held in the Letter of Credit Collateral Account, except as provided in Section
6.4(h) hereof.

          (e)  The Borrower agrees that it will not (i) sell or otherwise
dispose of any interest in the Letter of Credit Collateral or (ii) create or
permit to exist any lien, security interest or other charge or encumbrance upon
or with respect to any of the Letter of Credit Collateral, except for the
security interest created by this Section 6.4.

          (f)  If any Event of Default shall have occurred and be continuing:

          (i)  The Administrative Agent may, in its sole discretion without
notice to the Borrower except as required by law and at any time from time to
time, charge, set off or otherwise 

                                       75
<PAGE>
 
apply all or any part of first, (x) to amounts previously drawn on any Letter of
Credit that have not been reimbursed by the Borrower and (y) any Letter of
Credit Usage described in clause (ii) of the definition thereof that are then
due and payable and second, to any other unpaid obligations then due and payable
against the Letter of Credit Collateral Account or any part thereof, in such
order as the Administrative Agent shall elect. The rights of the Administrative
Agent under this Section 6.4 are in addition to any rights and remedies which
any Bank may have.

               (ii)   The Administrative Agent may also exercise, in its sole
discretion, in respect of the Letter of Credit Collateral Account, in addition
to the other rights and remedies provided herein or otherwise available to it,
all the rights and remedies of a secured party upon default under the Uniform
Commercial Code in effect in the Commonwealth of Virginia at that time.

          (g)  The Administrative Agent shall be deemed to have exercised
reasonable care in the custody and preservation of the Letter of Credit
Collateral if the Letter of Credit Collateral is accorded treatment
substantially equal to that which the Administrative Agent accords its own
property, it being understood that, assuming such treatment, the Administrative
Agent shall not have any responsibility or liability with respect thereto.

          (h)  At such time as all Events of Default have been cured or waived
in writing, all amounts remaining in the Letter of Credit Collateral Account
shall be promptly returned to the Borrower. Absent such cure or written waiver,
any surplus of the funds held in the Letter of Credit Collateral Account and
remaining after payment in full of all of the Obligations of the Borrower
hereunder and under any other Loan Document after the Maturity Date shall be
paid to the Borrower or to whomsoever may be lawfully entitled to receive such
surplus.

      SECTION 6.5. Distribution of Proceeds after Default.
                   -------------------------------------- 

     Notwithstanding anything contained herein to the contrary, during the
continuance of an Event of Default, to the extent proceeds are received by
Administrative Agent, such proceeds will be distributed to the Banks pro rata in
accordance with the unpaid principal amount of the Loans.

                                  ARTICLE VII
                           THE ADMINISTRATIVE AGENT
      SECTION 7.1.  Appointment and Authorization.
                    ----------------------------- 

     Each Bank irrevocably appoints and authorizes the Administrative Agent to
take such action as agent on its behalf and to exercise such powers under this
Agreement and the other Loan Documents as are delegated to the Administrative
Agent by the terms hereof or thereof, together with all such powers as are
reasonably incidental thereto.  Except as set forth in Sections 7.8 and 7.9
hereof, the provisions of this Article VII are solely for the benefit of
Administrative Agent and the Banks, and Borrower shall not have any rights to
rely on or enforce any of the provisions hereof.  In performing its functions
and duties under this Agreement, Administrative Agent shall act solely as an
agent of the Banks and the Fronting Bank and does not assume and shall not be
deemed to have 

                                       76
<PAGE>
 
assumed any relationship of agency or trust with or for the Borrower.

      SECTION 7.2.  Agency and Affiliates.
                    --------------------- 

     PNC shall have the same rights and powers under this Agreement as any other
Bank and may exercise or refrain from exercising the same as though it were not
the Administrative Agent and PNC and its affiliates may accept deposits from,
lend money to, and generally engage in any kind of business with the Borrower,
CESRRI or any Subsidiary or affiliate of the Borrower as if it was not the
Administrative Agent hereunder, and the term "Bank" and "Banks" shall include
PNC in its individual capacity.

      SECTION 7.3. Action by Administrative Agent.
                   ------------------------------ 

     The obligations of the Administrative Agent hereunder are only those
expressly set forth herein.  Without limiting the generality of the foregoing,
the Administrative Agent shall not be required to take any action with respect
to any Default or Event of Default, except as expressly provided in Article VI.
The duties of Administrative Agent  shall be administrative in nature.  Subject
to the provisions of Sections 7.1, 7.5 and 7.6,  the Administrative Agent shall
perform its obligations under this Agreement and the other Loan Documents in
good faith according to the same standard of care as that customarily exercised
by the Administrative Agent in administering its own similar loans, and shall at
all times keep accurate books of account reflecting the interests of the Banks
in the Loans. Such books shall be available to the Banks for inspection during
business hours with reasonable notice to the Administrative Agent.  Except as
stated in the preceding two (2) sentences or as otherwise expressly set forth in
this Agreement, the Administrative Agent shall have no duties or
responsibilities except those expressly set forth in this Agreement, and no
implied covenants, functions, responsibilities, duties, obligations, or
liabilities shall be read into this Agreement or otherwise exist. The duties of
the Administrative Agent shall be mechanical and administrative in nature; the
Administrative Agent shall not have by reason of this Agreement or any other
Loan Document a fiduciary relationship in respect of any Bank; and nothing in
this Agreement or any other Loan Document, expressed or implied, is intended to
or shall be construed so as to impose upon the Administrative Agent any
obligations in respect of this Agreement except as expressly set forth herein.
Without limiting the generality of the foregoing, the use of the term "agent" in
this Agreement with reference to the Administrative Agent is not intended to
connote any fiduciary or other implied (or express) obligations arising under
agency doctrine of any applicable law.  Instead, such term is used merely as a
matter of market custom, and is intended to create or reflect only an
administrative relationship between independent contracting parties.  Each Bank
expressly acknowledges (i) that the Administrative Agent has not made any
representations or warranties to them and that no act by the Administrative
Agent hereafter taken, including any review of the affairs of the Borrower,
shall be deemed to constitute any representation or warranty by the
Administrative Agent to any Bank; and (ii) except as expressly provided herein,
that the Administrative Agent shall have no duty or responsibility, either
initially or on a continuing basis, to provide any Bank with credit or other
information with respect thereto, whether coming into its possession before the
making of the Loans or at any time or times thereafter.

      SECTION 7.4.  Consultation with Experts.
                    ------------------------- 

     As between Administrative Agent and the Banks, the Administrative Agent may
consult with legal counsel, independent public accountants and other experts
selected by it and shall not be liable for any action taken or omitted to be
taken by it in good faith in accordance with the advice of such counsel,
accountants or experts.

      SECTION 7.5.  Liability of Administrative Agent.
                    --------------------------------- 

     As between Administrative Agent and the Banks, neither the Administrative
Agent, nor any of its affiliates nor any of its directors, officers, agents or
employees shall be liable for any action taken or not taken by it in connection
herewith (i) with the consent or at the request of the Required Banks or (ii) in
the absence of its own gross negligence or wilful misconduct.  As between
Administrative Agent and the Banks, neither the Administrative Agent, nor any of
its directors, officers, agents or employees shall be responsible for or have
any duty to ascertain, inquire into or verify (i) any statement, warranty or
representation made in connection with this Agreement or any borrowing
hereunder; (ii) the performance or observance of any of the covenants or
agreements of the Borrower; (iii) the satisfaction of any condition specified in
Article III, except receipt of items required to be delivered to the
Administrative Agent or (iv) the validity, effectiveness or genuineness of this
Agreement, the other Loan Documents or any other instrument or writing furnished
in connection herewith.  As between Administrative Agent and the Banks, the
Administrative Agent shall not incur any liability by acting in reliance upon
any notice, consent, certificate, statement, or other writing (which may be a
bank wire, telex or similar writing) believed by it to be genuine or to be
signed by the proper party or parties.

      SECTION 7.6.  Indemnification.
                    --------------- 

     Each Bank shall, ratably in accordance with its Commitment, indemnify the
Administrative Agent and its affiliates and its directors, officers, agents and
employees (to the extent not reimbursed by the Borrower) against any cost,
expense (including counsel fees and disbursements), claim, demand, action, loss
or liability (except such as result from such indemnitee's gross negligence or
wilful misconduct) that such indemnitee may suffer or incur in connection with
its duties as Administrative Agent under this Agreement, the other Loan
Documents or any action taken or omitted by such indemnitee hereunder.  In the
event that the Administrative Agent shall, subsequent to its receipt of
indemnification payment(s) from Banks in accordance with this section, recoup
any amount from the Borrower, or any other party liable therefor in connection
with such indemnification, the Administrative Agent shall reimburse the Banks
which previously made the payment(s) pro rata, based upon the actual amounts
                                     --------                               
which were theretofore paid by each Bank.  The Administrative Agent shall
reimburse such Banks so entitled to reimbursement within two (2) Domestic
Business Days of its receipt of such funds from the Borrower or such other party
liable therefor.

      SECTION 7.7. Credit Decision.
                   --------------- 

     Each Bank acknowledges that it has, independently and without reliance upon
the Administrative Agent, or any other Bank, and based on such documents and
information as it has 

                                       78
<PAGE>
 
deemed appropriate, made its own credit analysis and decision to enter into this
Agreement. Each Bank also acknowledges that it will, independently and without
reliance upon the Administrative Agent, or any other Bank, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking any action under this
Agreement.

      SECTION 7.8.  Successor Administrative Agent.
                    ------------------------------ 

     The Administrative Agent may resign at any time by giving written notice
thereof to the Banks and the Borrower and shall resign, at the request of the
Required Banks, in the event its Commitment is reduced to an amount less than
the amount of the next largest Commitment.  Further, the Required Banks may, for
good cause, remove Administrative Agent at any time by giving at least thirty
(30) Domestic Business Days' prior written notice to the Borrower and all other
Banks. Upon any such resignation or removal, the Required Banks shall have the
right to appoint a successor Administrative Agent, which shall be selected by
the Required Banks from between NationsBank, N.A. and U.S. Bank National
Association.  In the event that both NationsBank, N.A., and U.S. Bank National
Association shall decline to serve, or following their resignation or removal,
the Required Banks shall have the right to appoint a successor Administrative
Agent, which successor Administrative Agent (other than NationsBank, N.A., and
U.S. Bank National Association) shall, provided no Event of Default has occurred
and is then continuing, be subject to Borrower's approval, which approval shall
not be unreasonably withheld or delayed.  Any successor Administrative Agent
must be a Bank (i) the senior debt obligations of which (or such Bank's parent's
senior unsecured debt obligations) are rated not less than Baa by Moody's or a
comparable rating by a rating agency acceptable to the Required Banks and (ii)
which has total assets in excess of Ten Billion Dollars ($10,000,000,000).    If
no successor Administrative Agent shall have been so appointed by the Required
Banks and approved by the Borrower, and shall have accepted such appointment,
within 30 days after the retiring Administrative Agent gives notice of
resignation, then the retiring Administrative Agent may, on behalf of the Banks,
appoint a successor Administrative Agent, which shall be the Administrative
Agent, who shall act until the Required Banks shall appoint a successor
Administrative Agent.  Upon the acceptance by a successor Administrative Agent
of its appointment as the Administrative Agent hereunder, such successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights and duties of the retiring Administrative Agent, and the retiring
Administrative Agent shall be discharged from its duties and obligations
hereunder.  After any retiring Administrative Agent's resignation hereunder, the
provisions of this Article VII shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was the Administrative Agent as
applicable.  Any resignation or removal of the Administrative Agent shall take
effect upon the acceptance of appointment by a successor Administrative Agent in
accordance with the provisions of this Section 7.8.

      SECTION 7.9.  Consents and Approvals.
                    ---------------------- 

     (a) All communications from Administrative Agent to the Banks requesting
the Banks' determination, consent, approval or disapproval (i) shall be given in
the form of a written notice to each Bank, (ii) shall be accompanied by a
description of the matter or item as to which such determination, approval,
consent or disapproval is requested, or shall advise each Bank where such 

                                       79
<PAGE>
 
matter or item may be inspected, or shall otherwise describe the matter or issue
to be resolved, (iii) shall include, if reasonably requested by a Bank and to
the extent not previously provided to such Bank, written materials and a summary
of all oral information provided to Administrative Agent by Borrower in respect
of the matter or issue to be resolved, and (iv) shall include Administrative
Agent's recommended course of action or determination in respect thereof. Each
Bank shall reply promptly, but in any event within ten (10) Domestic Business
Days after receipt of the request therefor from Administrative Agent (the "Bank
Reply Period"). Unless a Bank shall give written notice to Administrative Agent
that it objects to the recommendation or determination of Administrative Agent
(together with a written explanation of the reasons behind such objection)
within the Bank Reply Period, such Bank shall be deemed to have approved of or
consented to such recommendation or determination. With respect to decisions
requiring the approval of the Required Banks or all the Banks, Administrative
Agent shall submit its recommendation or determination for approval of or
consent to such recommendation or determination to all Banks and upon receiving
the required approval or consent shall follow the course of action or
determination of the Required Banks (and each non-responding Bank shall be
deemed to have concurred with such recommended course of action) or all the
Banks, as the case may be.

     (b) The Administrative Agent may at any time request instructions from the
Required Banks with respect to any actions or approvals which, by the terms of
this Agreement or of any of the Loan Documents, the Administrative Agent is
permitted or required to take or to grant without instructions from any Banks,
and if such instructions are promptly requested, the Administrative Agent shall
be absolutely entitled to refrain from taking any action or to withhold any
approval and shall not be under any liability whatsoever to any Person for
refraining from taking any action or withholding any approval under any of the
Loan Documents until it shall have received such instructions from the Required
Banks.  Without limiting the foregoing, no Bank shall have any right of action
whatsoever against the Administrative Agent as a result of the Administrative
Agent acting or refraining from acting under this Agreement, or any of the other
Loan Documents in accordance with the instructions of Required Banks or, where
applicable, all Banks.  The Administrative Agent shall promptly notify each Bank
at any time that the Required Banks have instructed the Administrative Agent to
act or refrain from acting pursuant hereto.  Each Bank agrees that any action
taken by the Administrative Agent at the direction or with the consent of
Required Banks in accordance with the provisions of this Agreement or any Loan
Document, and the exercise by the Administrative Agent at the direction or with
the consent of Required Banks of the powers set forth herein or therein,
together with such other powers as are reasonably incidental thereto, shall be
authorized and binding upon all Required Banks, except for actions specifically
requiring the approval of all Banks.

      SECTION 7.10.  Delivery of Documents.
                     --------------------- 

     The Administrative Agent shall as soon as reasonably practicable and, in
any event, within thirty (30) days, distribute to each Bank at its primary
address set forth on the appropriate counterpart signature page hereof, or at
such other address as a Bank may request in writing, (i) such Bank's Notes, (ii)
all documents set forth on the Closing Requirements attached hereto as Exhibit
O, (iii) all other documents or information which the Administrative Agent is
required to send to Banks pursuant to the terms of this Agreement, and (iv)
other information or documents received by the 

                                       80
<PAGE>
 
Administrative Agent at the request of any Bank. In addition, within fifteen
(15) Domestic Business Days after receipt of a request in writing from a Bank
for written information or documents provided by or prepared by Borrower, CESRRI
or any Consolidated Subsidiary or Investment Affiliate, the Administrative Agent
shall deliver such written information or documents to such requesting Bank if
Administrative Agent has possession of such written information or documents in
its capacity as the Administrative Agent or as a Bank.

     SECTION 7.11.  Inspection of Books and Records.
                    ------------------------------- 

     Subject to the provisions of Section 5.6, each Bank shall have the right to
exercise the rights of the Administrative Agent set forth in the Loan Documents
to inspect the books and records of the Borrower, CESSRI, any Consolidated
Subsidiary and any other Person.

     SECTION 7.12.  Administrative Agent's Commitment.
                    --------------------------------- 

     Prior to any Event of Default, PNC agrees to retain a Commitment, in an
amount equal to or greater than the Commitment of any other Bank.

                                 ARTICLE VIII

                            CHANGE IN CIRCUMSTANCES

     SECTION 8.1.   Basis for Determining Interest Rate Inadequate or Unfair.
                    -------------------------------------------------------- 

     If on or prior to the first day of any Interest Period for any Euro-Dollar
Borrowing or Money Market LIBOR Loan:

          (a)  the Administrative Agent has determined in good faith that
deposits in dollars (in the applicable amounts) are not being offered to the
Administrative Agent in the relevant market for such Interest Period, or

          (b)  Banks having 50% or more of the aggregate amount of the
Commitments advise the Administrative Agent that the Adjusted London Interbank
Offered Rate, as determined by the Administrative Agent, or any Bank making a
Money Market LIBOR Loan advises the Administrative Agent that the applicable
Money Market Margin quoted by such Bank, will not adequately and fairly reflect
the cost to such Bank of funding its Euro-Dollar Loans or the Money Market LIBOR
Loans, as applicable, for such Interest Period, the Administrative Agent shall
forthwith give notice thereof to the Borrower and the Banks, whereupon until the
Administrative Agent notifies the Borrower that the circumstances giving rise to
such suspension no longer exist, the obligations of the Banks to make Euro-
Dollar Loans and Money Market LIBOR Loans shall be suspended.  Unless the
Borrower notifies the Administrative Agent at least two (2) Domestic Business
Days before the date of (i) any Euro-Dollar Borrowing for which a Notice of
Borrowing has previously been given that it elects not to borrow on such date,
such Borrowing shall instead be made as a Base Rate Borrowing, or (ii) any Money
Market LIBOR Borrowing for which a Notice of Money Market Borrowing has
previously been given, the Money Market LIBOR Loans comprising such 

                                       81
<PAGE>
 
Borrowing shall bear interest for each day from and including the first day to
but excluding the last day of the Interest Period applicable thereto at the Base
Rate for such day.

     SECTION 8.2.   Illegality.
                    ---------- 

     If, on or after the date of this Agreement, the adoption of any applicable
law, rule or regulation, or any change in any applicable law, rule or
regulation, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Bank (or its
Euro-Dollar Lending Office) with any request or directive (whether or not having
the force of law) made after the Closing Date of any such authority, central
bank or comparable agency shall make it unlawful for any Bank (or its Euro-
Dollar Lending Office) (x) to make, maintain or fund its Euro-Dollar Loans or
Money Market Loans, or (y) to participate in any Letter of Credit issued by the
Fronting Bank, or, with respect to the Fronting Bank, to issue any Letter of
Credit, the Administrative Agent shall forthwith give notice thereof to the
other Banks and the Borrower, whereupon until such Bank notifies the Borrower
and the Administrative Agent that the circumstances giving rise to such
suspension no longer exist, the obligation of such Bank in case of the event
described in clause (x) above to make Euro-Dollar Loans or Money Market Loans,
as applicable or in the case of the event described in clause (y) above, to
participate in any Letter of Credit issued by the Fronting Bank or, with respect
to the Fronting Bank, to issue any Letter of Credit, shall be suspended.  With
respect to Euro-Dollar Loans and Money Market LIBOR Loans, before giving any
notice to the Administrative Agent pursuant to this Section 8.2, such Bank shall
designate a different Euro-Dollar Lending Office if such designation will avoid
the need for giving such notice and will not, in the judgment of such Bank, be
otherwise disadvantageous to such Bank.  If such Bank shall determine that it
may not lawfully continue to maintain and fund any of its outstanding Euro-
Dollar Loans or Money Market Loans to maturity and shall so specify in such
notice, the Borrower shall be deemed to have delivered a Notice of Interest Rate
Election and such Euro-Dollar Loan or Money Market Loans, as applicable shall be
converted as of such date to a Base Rate Loan in an equal principal amount from
such Bank (on which interest and principal shall be payable contemporaneously
with the related Euro-Dollar Loans  or Money Market Loans, as applicable, of the
other Banks), and such Bank shall be deemed to have made such a Base Rate Loan.

     If at any time, it shall be unlawful for any Bank to make, maintain or fund
its Euro-Dollar Loans or Money Market Loans, the Borrower shall have the right,
upon five (5) Domestic Business Day's notice to the Administrative Agent, to
either (x) cause a bank, reasonably acceptable to the Administrative Agent, to
offer to purchase the Commitment of such Bank for an amount equal to such Bank's
outstanding Loans, and to become a Bank hereunder, or obtain the agreement of
one or more existing Banks to offer to purchase the Commitment of such Bank for
such amount, which offer such Bank is hereby required to accept, or (y) repay in
full all Loans then outstanding of such Bank, together with interest and all
other amounts due thereon, upon which event, such Bank's Commitment shall be
deemed to be canceled pursuant to Section 2.11(e).

      SECTION 8.3.  Increased Cost and Reduced Return.
                    --------------------------------- 

          (a)  If, on or after (x) the date hereof in the case of Committed
Loans made 

                                       82
<PAGE>
 
pursuant to Section 2.1, or (y) the date of the related Money Market Quote, in
the case of any Money Market Loan, the adoption of any applicable law, rule or
regulation, or any change in any applicable law, rule or regulation, or any
change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank (or its Applicable Lending
Office) with any request or directive (whether or not having the force of law)
of any such authority, central bank or comparable agency shall impose, modify or
deem applicable any reserve (including, without limitation, any such requirement
imposed by the Board of Governors of the Federal Reserve System (but excluding
with respect to any Euro-Dollar Loan any such requirement reflected in an
applicable Euro-Dollar Reserve Percentage)), special deposit, insurance
assessment or similar requirement against assets of, deposits with or for the
account of, or credit extended by, any Bank (or its Applicable Lending Office)
or shall impose on any Bank (or its Applicable Lending Office) or on the London
interbank market any other condition materially more burdensome in nature,
extent or consequence than those in existence as of the Closing Date, or the
date of the related Money Market Quote, as applicable, affecting such Bank's
Euro-Dollar Loans, Money Market Loans, its Note, or its obligation to make Euro-
Dollar Loans or Money Market Loans, and the result of any of the foregoing is to
increase the cost to such Bank (or its Applicable Lending office) of making or
maintaining any Euro-Dollar Loan or Money Market Loan, or to reduce the amount
of any sum received or receivable by such Bank (or its Applicable Lending
Office) under this Agreement or under its Note with respect to such Euro-Dollar
Loans or Money Market Loans, by an amount reasonably deemed by such Bank to be
material, then, within fifteen (15) days after demand by such Bank (with a copy
to the Administrative Agent), the Borrower shall pay to such Bank such
additional amount or amounts (based upon a reasonable allocation thereof by such
Bank to the Euro-Dollar Loans and Money Market Loans made by such Bank
hereunder) as will compensate such Bank for such increased cost or reduction to
the extent such Bank generally imposes such additional amounts on other
borrowers of such Bank in similar circumstances.

          (b)  If any Bank shall have reasonably determined that, after the date
hereof, the adoption of any applicable law, rule or regulation regarding capital
adequacy, or any change in any such law, rule or regulation, or any change in
the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy
(whether or not having the force of law) made after the Closing Date of any such
authority, central bank or comparable agency, has or would have the effect of
reducing the rate of return on capital of such Bank (or its Parent) as a
consequence of such Bank's obligations hereunder to a level below that which
such Bank (or its Parent) could have achieved but for such adoption, change,
request or directive (taking into consideration its policies with respect to
capital adequacy) by an amount reasonably deemed by such Bank to be material,
then from time to time, within fifteen (15) days after demand by such Bank (with
a copy to the Administrative Agent), the Borrower shall pay to such Bank such
additional amount or amounts as will compensate such Bank (or its Parent) for
such reduction to the extent such Bank generally imposes such additional amounts
on other borrowers of such Bank in similar circumstances.

          (c)  Each Bank will promptly notify the Borrower and the
Administrative Agent of any event of which it has knowledge, occurring after the
date hereof, which will entitle such Bank to compensation pursuant to this
Section 8.3 and will designate a different Applicable Lending Office 

                                       83
<PAGE>
 
if such designation will avoid the need for, or reduce the amount of, such
compensation and will not, in the reasonable judgment of such Bank, be otherwise
disadvantageous to such Bank. A certificate of any Bank claiming compensation
under this Section 8.3 and setting forth a reasonably detailed calculation of
the additional amount or amounts to be paid to it hereunder shall be conclusive
in the absence of demonstrable error. In determining such amount, such Bank may
use any reasonable averaging and attribution methods.

          (d)  If at any time, any Bank shall be owed amounts pursuant to this
Section 8.3, the Borrower shall have the right, upon five (5) Domestic Business
Day's notice to the Administrative Agent to either (x) cause a bank, reasonably
acceptable to the Administrative Agent, to offer to purchase the Commitment of
such Bank for an amount equal to such Bank's outstanding Loans, and to become a
Bank hereunder, or to obtain the agreement of one or more existing Banks to
offer to purchase the Commitment of such Bank for such amount, which offer such
Bank is hereby required to accept, or (y) repay in full all Loans then
outstanding of such Bank, together with interest and all other amounts due
thereon, upon which event, such Bank's Commitment shall be deemed to be canceled
pursuant to Section 2.11(e).

      SECTION 8.4.  Taxes.
                    ----- 

          (a)  Any and all payments by the Borrower to or for the account of any
Bank, or the Administrative Agent hereunder or under any other Loan Document
shall be made free and clear of and without deduction for any and all present or
future taxes, duties, levies, imposts, deductions, charges or withholdings, and
all liabilities with respect thereto, excluding, in the case of each Bank and
the Administrative Agent, taxes imposed on its income, and franchise taxes
imposed on it, by the jurisdiction under the laws of which such Bank or the
Administrative Agent (as the case may be) is organized or any political
subdivision thereof and, in the case of each Bank, taxes imposed on its income,
and franchise or similar taxes imposed on it, by the jurisdiction of such Bank's
Applicable Lending Office or any political subdivision thereof or by any other
jurisdiction (or any political subdivision thereof) as a result of a present or
former connection between such Bank or Administrative Agent and such other
jurisdiction or by the United States (all such non-excluded taxes, duties,
levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Non-Excluded Taxes"). If the Borrower shall be
required by law to deduct any Non-Excluded Taxes from or in respect of any sum
payable hereunder or under any Note or Letter of Credit, (i) the sum payable
shall be increased as necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
8.4) such Bank, the Fronting Bank or, the Administrative Agent (as the case may
be) receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions, (iii) the
Borrower shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law and (iv) the Borrower shall
furnish to the Administrative Agent, at its address referred to in Section 9.1,
the original or a copy of a receipt evidencing payment thereof.

          (b)  In addition, the Borrower agrees to pay any present or future
stamp or documentary taxes and any other excise or property taxes, or charges or
similar levies which arise from any payment made hereunder or under any Note or
Letter of Credit or from the execution or delivery of, or otherwise with respect
to, this Agreement or any Note or Letter of Credit (hereinafter 

                                       84
<PAGE>
 
referred to as "Other Taxes").

          (c)  The Borrower agrees to indemnify each Bank, the Fronting Bank,
and the Administrative Agent for the full amount of Non-Excluded Taxes or Other
Taxes (including, without limitation, any Non-Excluded Taxes or Other Taxes
imposed or asserted by any jurisdiction on amounts payable under this Section
8.4) paid by such Bank, the Fronting Bank, or the Administrative Agent (as the
case may be) and, so long as such Bank, the Fronting Bank or the Administrative
Agent has promptly paid any such Non-Excluded Taxes or Other Taxes, any
liability for penalties and interest arising therefrom or with respect thereto.
This indemnification shall be made within fifteen (15) days from the date such
Bank, the Fronting Bank, or the Administrative Agent (as the case may be) makes
demand therefor.

          (d)  Each Bank organized under the laws of a jurisdiction outside the
United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Bank listed on the signature pages hereof and on
or prior to the date on which it becomes a Bank in the case of each other Bank,
shall provide the Borrower with (A) two duly completed copies of Internal
Revenue Service Form 1001 or 4224, as appropriate, or any successor form
prescribed by the Internal Revenue Service, and (B) an Internal Revenue Service
Form W-8 or W-9, or any successor form prescribed by the Internal Revenue
Service, and shall provide Borrower with two further copies of any such form or
certification on or before the date that any such form or certification expires
or becomes obsolete and after the occurrence of any event requiring a change in
the most recent form previously delivered by it to Borrower, certifying (i) in
the case of a Form 1001 or 4224, that such Bank is entitled to benefits under an
income tax treaty to which the United States is a party which reduces the rate
of withholding tax on payments of interest or certifying that the income
receivable pursuant to this Agreement is effectively connected with the conduct
of a trade or business in the United States, and (ii) in the case of a Form W-8
or W-9, that it is entitled to an exemption from United States backup
withholding tax.  If the form provided by a Bank at the time such Bank first
becomes a party to this Agreement indicates a United States interest withholding
tax rate in excess of zero, withholding tax at such rate shall be considered
excluded from "Non-Excluded Taxes" as defined in Section 8.4(a).

          (e)  For any period with respect to which a Bank has failed to provide
the Borrower with the appropriate form pursuant to Section 8.4(d) (unless such
failure is due to a change in treaty, law or regulation occurring subsequent to
the date on which a form originally was required to be provided), such Bank
shall not be entitled to indemnification under Section 8.4(c) with respect to
Non-Excluded Taxes imposed by the United States; provided, however, that should
a Bank, which is otherwise exempt from or subject to a reduced rate of
withholding tax, become subject to Non-Excluded Taxes because of its failure to
deliver a form required hereunder, the Borrower shall take such steps as such
Bank shall reasonable request to assist such Bank to recover such Taxes so long
as Borrower shall incur no cost or liability as a result thereof.

          (f)  If the Borrower is required to pay additional amounts to or for
the account of any Bank pursuant to this Section 8.4, then such Bank will change
the jurisdiction of its Applicable Lending Office so as to eliminate or reduce
any such additional payment which may thereafter accrue if such change, in the
judgment of such Bank, is not otherwise disadvantageous to such Bank.

                                       85
<PAGE>
 
          (g)  If at any time, any Bank shall be owed amounts pursuant to this
Section 8.4, the Borrower shall have the right, upon five (5) Domestic Business
Day's notice to the Administrative Agent to either (x) cause a bank, reasonably
acceptable to the Administrative Agent, to offer to purchase the Commitment of
such Bank for an amount equal to such Bank's outstanding Loans, and to become a
Bank hereunder, or to obtain the agreement of one or more existing Banks to
offer to purchase the Commitment of such Bank for such amount, which offer such
Bank is hereby required to accept, or (y) repay in full all Loans then
outstanding of such Bank, together with interest and all other amounts due
thereon, upon which event, such Bank's Commitment shall be deemed to be canceled
pursuant to Section 2.11(e).

     SECTION 8.5.   Base Rate Loans Substituted for Affected Euro-Dollar Loans.
                    ---------------------------------------------------------- 

     If (i) the obligation of any Bank to make Euro-Dollar Loans or Money Market
Loans has been suspended pursuant to Section 8.2 or (ii) any Bank has demanded
compensation under Section 8.3 or 8.4 with respect to its Euro-Dollar Loans or
Money Market Loans and the Borrower shall, by at least five (5) Euro-Dollar
Business Days' prior notice to such Bank through the Administrative Agent, have
elected that the provisions of this Section 8.5 shall apply to such Bank, then,
unless and until such Bank notifies the Borrower that the circumstances giving
rise to such suspension or demand for compensation no longer exist:

          (a)  Borrower shall be deemed to have delivered a Notice of Interest
Rate Election with respect to such affected Euro-Dollar Loans or Money Market
Loans and thereafter all Loans which would otherwise be made by such Bank as
Euro-Dollar Loans or Money Market Loans shall be made instead as Base Rate Loans
(on which interest and principal shall be payable contemporaneously with the
related Euro-Dollar Loans or Money Market Loans of the other Banks), and

          (b)  after each of its Euro-Dollar Loans or Money Market Loans has
been repaid, all payments of principal which would otherwise be applied to repay
such Euro-Dollar Loans or Money Market Loans shall be applied to repay its Base
Rate Loans instead.


                                  ARTICLE IX

                                 MISCELLANEOUS

     SECTION 9.1.   Notices.

address, telex number or facsimile number set forth on Schedule II hereto , or
(y) in the case of any party, such other address, telex number or facsimile
number as such party may hereafter specify for the purpose by notice to the
Administrative Agent and the Borrower.  Each such notice, request or other
communication shall be effective (i) if given by telex or facsimile

                                       86
<PAGE>
 
transmission, when such telex or facsimile is transmitted to the telex number or
facsimile number specified in this Section 9.1 and the appropriate answerback or
facsimile confirmation is received, (ii) if given by certified registered mail,

nationally recognized overnight carrier, twenty-four (24) hours after such
communication is deposited with such carrier with postage prepaid for next day
delivery, or (iv) if given by any other means, when delivered at the address
specified in this Section 9.1; provided that notices to the Administrative Agent
                               --------                                         
under Article II or Article VIII shall not be effective until received.

     SECTION 9.2.   No Waivers.
                    ---------- 

     No failure or delay by the Administrative Agent, or any Bank in exercising
any right, power or privilege hereunder or under any Note shall operate as a
waiver thereof nor shall any single or partial exercise thereof preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege.  The rights and remedies herein provided shall be cumulative and not
exclusive of any rights or remedies provided by law.

     SECTION 9.3.   Expenses; Indemnification.
                    ------------------------- 

          (a)  The Borrower shall pay within thirty (30) days after written
notice from the Administrative Agent (i) all reasonable out-of-pocket costs and
expenses of the Administrative Agent (including reasonable fees and
disbursements of special counsel Marcus & Shapira, LLP), in connection with the
preparation of this Agreement, the Loan Documents and the documents and
instruments referred to therein, and any waiver or consent hereunder or any
amendment hereof or any Default or alleged Default hereunder, (ii) all
reasonable out-of-pocket costs and expenses of PNC in connection with the
syndication of the Loans, subject to a maximum reimbursement of $10,000, and, in
addition thereto, all reasonable fees and disbursements of special counsel
Marcus & Shapira, LLP in connection with the syndication of the Loans, (iii) any
reasonable out-of-pocket costs and expenses incurred by Administrative Agent to
verify the status of any Property as a Qualifying Unencumbered Property,
including, without limitation, any title searches, lien checks and other similar
actions, and (iv) if an Event of Default should be continuing, all reasonable
out-of-pocket expenses incurred by the Administrative Agent, and each Bank,
including reasonable fees and disbursements of counsel for the Administrative
Agent, and each of the Banks, in connection with the enforcement of the Loan
Documents and the instruments referred to therein and such Event of Default and
collection, bankruptcy, insolvency and other enforcement proceedings resulting
therefrom.

          (b)  The Borrower agrees to indemnify the Administrative Agent, and
each Bank, their respective affiliates and the respective directors, officers,
agents and employees of the foregoing (each an "Indemnitee") and hold each
Indemnitee harmless from and against any and all liabilities, losses, damages,
reasonable costs and reasonable expenses of any kind, including, without
limitation, the reasonable fees and disbursements of counsel, which may be
incurred by such Indemnitee in connection with any investigative, administrative
or judicial proceeding that may at any time (including, without limitation, at
any time following the payment of the Obligations) be asserted against any
Indemnitee, as a result of, or arising out of, or in any way related to or by
reason of, (i) any of the transactions contemplated by the Loan Documents or the
execution, delivery or 

                                       87
<PAGE>
 
performance of any Loan Document, (ii) any violation by the Borrower or the
Environmental Affiliates of any applicable Environmental Law, (iii) any
Environmental Claim arising out of the management, use, control, ownership or
operation of property or assets by the Borrower or any of the Environmental
Affiliates, including, without limitation, all on-site and off-site activities
of Borrower or any Environmental Affiliate involving Materials of Environmental
Concern, (iv) the breach of any environmental representation or warranty set
forth herein, but excluding those liabilities, losses, damages, costs and
expenses (a) for which such Indemnitee has been compensated pursuant to the
terms of this Agreement, (b) incurred solely by reason of the gross negligence,
wilful misconduct, bad faith or fraud of any Indemnitee as finally determined by
a court of competent jurisdiction, (c) violations of Environmental Laws relating
to a Property which are caused by the act or omission of such Indemnitee after
such Indemnitee takes possession of such Property or (d) any liability of such
Indemnitee to any third party based upon contractual obligations of such
Indemnitee owing to such third party which are not expressly set forth in the
Loan Documents. In addition, the indemnification set forth in this Section
9.3(b) in favor of any director, officer, agent or employee of Administrative
Agent, or any Bank shall be solely in their respective capacities as such
director, officer, agent or employee. The Borrower's obligations under this
Section 9.3(b) shall survive the termination of this Agreement and the payment
of the Obligations.

     SECTION 9.4.   Sharing of Set-Offs.
                    ------------------- 

     In addition to any rights now or hereafter granted under applicable law or
otherwise, and not by way of limitation of any such rights, upon the occurrence
and during the continuance of any Event of Default, each Bank is hereby
authorized at any time or from time to time, without presentment, demand,
protest or other notice of any kind to the Borrower or to any other Person, any
such notice being hereby expressly waived, but subject to the prior consent of
the Administrative Agent, to set off and to appropriate and apply any and all
deposits (general or special, time or demand, provisional or final) and any
other indebtedness at any time held or owing by such Bank (including, without
limitation, by branches and agencies of such Bank wherever located) to or for
the credit or the account of the Borrower against and on account of the
Obligations of the Borrower then due and payable to such Bank under this
Agreement or under any of the other Loan Documents, including, without
limitation, all interests in Obligations purchased by such Bank. Each Bank
agrees that if it shall by exercising any right of set-off or counterclaim or
otherwise, receive payment of a proportion of the aggregate amount of principal
and interest due with respect to any Note held by it or Letter of Credit
participated in by it, or, in the case of the Fronting Bank, Letter of Credit
issued by it, which is greater than the proportion received by any other Bank or
Letter of Credit issued or participated in by such other Bank, the Bank
receiving such proportionately greater payment shall purchase such
participations in the Notes held by the other Banks, and such other adjustments
shall be made, as may be required so that all such payments of principal and
interest with respect to the Notes held by the Banks or Letter of Credit issued
or participated in by such other Banks shall be shared by the Banks pro rata;
provided that nothing in this Section 9.4 shall impair the right of any Bank to
exercise any right of set-off or counterclaim it may have to any deposits not
received in connection with the Loans and to apply the amount subject to such
exercise to the payment of indebtedness of the Borrower other than its
indebtedness under the Notes or the Letters of Credit.  The Borrower agrees, to
the fullest extent it may effectively do so under applicable law, that any
holder of a participation in a Note or a Letter of Credit, whether or not
acquired pursuant to the foregoing arrangements, may exercise 

                                       88
<PAGE>
 
rights of set-off or counterclaim and other rights with respect to such
participation as fully as if such holder of a participation were a direct
creditor of the Borrower in the amount of such participation. Notwithstanding
anything to the contrary contained herein, any Bank may, by separate agreement
with the Borrower, waive its right to set off contained herein or granted by law
and any such written waiver shall be effective against such Bank under this
Section 9.4.

     SECTION 9.5.   Amendments and Waivers.
                    ---------------------- 
 
     Any provision of this Agreement or the Notes, the Letters of Credit or
other Loan Documents may be amended or waived or consented to if, but only if,
such amendment, waiver or consent is in writing and is signed by the Borrower,
the Administrative Agent, and the Required Banks  provided that no such
amendment, waiver or consent with respect to this Agreement, the Notes, the
Letters of Credit or any other Loan Documents shall, unless signed by all the
Banks, (i) increase or decrease the Commitment of any Bank (except for a ratable
decrease in the Commitments of all Banks) or subject any Bank to any additional
obligation, (ii) reduce the principal of or rate of interest on any Loan or any
fees hereunder, (iii) postpone the date fixed for any payment of principal of or
interest on any Loan or any fees hereunder or for any reduction or termination
of any Commitment, (iv) change the percentage of the Commitments or of the
aggregate unpaid principal amount of the Notes, or the number of Banks, which
shall be required for the Banks or any of them to take any action under this
Section 9.5 or any other provision of this Agreement, (v) release the
Guaranties or (vi) modify the provisions of this Section 9.5.

     SECTION 9.6.   Successors and Assigns.
                    ---------------------- 

          (a)  The provisions of this Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and
assigns, except that the Borrower may not assign or otherwise transfer any of
its rights under this Agreement or the other Loan Documents without the prior
written consent of all Banks and the Administrative Agent and a Bank may not
assign or otherwise transfer any of its interest under this Agreement except as
permitted in subsection (b) and (c) of this Section 9.6.

          (b)  Any Bank may at any time grant (i) prior to the occurrence of an
Event of Default, to an existing Bank, one or more banks, finance companies,
insurance companies or other financial institutions in minimum amounts of not
less than $10,000,000 (or any lesser amount in the case of participations to an
existing Bank or in the case of participations with respect to Money Market
Loans only) and (ii) after the occurrence and during the continuance of an Event
of Default, to any Person in any amount (in each case, a "Participant"),
participating interests in its Commitment or any or all of its Loans, with (and
subject to) the consent of the Administrative Agent (other than with respect to
Money Market Loans) and, provided that no Event of Default shall have occurred
and be continuing, the Borrower, which consent shall not be unreasonably
withheld or delayed.  Any participation made during the continuation of an Event
of Default shall not be affected by the subsequent cure of such Event of
Default.  In the event of any such grant by a Bank of a participating interest
to a Participant, whether or not upon notice to the Borrower and the
Administrative Agent, such Bank shall remain responsible for the performance of
its obligations hereunder, and the Borrower and the Administrative Agent shall
continue to deal solely and directly with such Bank in 

                                       89
<PAGE>
 
connection with such Bank's rights and obligations under this Agreement. Any
agreement pursuant to which any Bank may grant such a participating interest
shall provide that such Bank shall retain the sole right and responsibility to
enforce the Obligations of the Borrower hereunder including, without limitation,
the right to approve any amendment, modification or waiver of any provision of
this Agreement; provided that such participation agreement may provide that such
                --------
Bank will not agree to any modification, amendment or waiver of this Agreement
described in clause (i), (ii), (iii), (iv) or (v) of Section 9.5 without the
consent of the Participant. The Borrower agrees that each Participant shall, to
the extent provided in its participation agreement, be entitled to the benefits
of Article VIII with respect to its participating interest. An assignment or
other transfer which is not permitted by subsection (c) or (d) below shall be
given effect for purposes of this Agreement only to the extent of, and subject
to the restrictions with respect to, a participating interest granted in
accordance with this subsection (b).

          (c)  Any Bank may at any time assign to (i) prior to the occurrence of
an Event of Default, an existing Bank or one or more banks, finance companies,
insurance or other financial institutions in minimum amounts of not less than
Ten Million Dollars ($10,000,000) (or any lesser amount in the case of
assignments to an existing Bank) and (ii) after the occurrence and during the
continuance of an Event of Default, to any Person in any amount (in each case,
an "Assignee"), all or a proportionate part of all, of its rights and
obligations under this Agreement, the Notes and the other Loan Documents, and,
in either case, such Assignee shall assume such rights and obligations, pursuant
to a an Assignment and Assumption Agreement in substantially the form of Exhibit
"E" hereto executed by such Assignee and such transferor Bank, with (and subject
to) the consent of the Administrative Agent and, provided that no Event of
Default shall have occurred and be continuing, the Borrower, which consent shall
not be unreasonably withheld or delayed; provided that if an Assignee is an
affiliate of such transferor Bank or was a Bank immediately prior to such
assignment, no such consent shall be required; and provided further that such
assignment may, but need not, include rights of the transferor Bank in respect
of outstanding Money Market Loans. Upon its receipt of an Assignment and
Assumption Agreement executed by a transferor Bank and an Assignee,
Administrative Agent shall, if such Assignment and Assumption Agreement has been
properly completed and is in substantially the form of Exhibit E, (i) accept
such Assignment and Assumption Agreement, (ii) record the information contained
therein in the Administrative Agent's records, and (iii) give prompt notice
thereof to Borrower. Upon execution and delivery of such instrument and payment
by such Assignee to such transferor Bank of an amount equal to the purchase
price agreed between such transferor Bank and such Assignee, such Assignee shall
be a Bank party to this Agreement and shall have all the rights and obligations
of a Bank with a Commitment as set forth in such instrument of assumption, and
no further consent or action by any party shall be required and the transferor
Bank shall be released from its obligations hereunder to a corresponding extent.
Upon the consummation of any assignment pursuant to this subsection (c), the
transferor Bank, the Administrative Agent and the Borrower shall make
appropriate arrangements so that, if required, new Notes are issued to the
Assignee, and, if necessary, to the transferor Bank. Upon execution and delivery
of such replacement Notes, the original Notes evidencing all or the portion of
the Commitment being assigned shall be canceled and returned to Borrower. In
connection with any such assignment, the transferor Bank shall pay to the
Administrative Agent an administrative fee for processing such assignment in the
amount of $3,000. If the Assignee is not incorporated under the laws of
the United States of America or a state thereof, it shall deliver to the
Borrower and the 

                                       90
<PAGE>
 
Administrative Agent certification as to exemption from deduction or withholding
of any United States federal income taxes in accordance with Section 8.4. Any
assignment made during the continuation of an Event of Default shall not be
affected by any subsequent cure of such Event of Default.

          (d)  Any Bank (each, a "Designating Lender") may at any time designate
one Designated Lender to fund Money Market Loans on behalf of such Designating
Lender subject to the terms of this Section 9.6(d) and the provisions in Section
9.6(b) and (c) shall not apply to such designation. No Bank may designate more
than one (1) Designated Lender at any one time. The parties to each such
designation shall execute and deliver to the Administrative Agent for its
acceptance a Designation Agreement. Upon such receipt of an appropriately
completed Designation Agreement executed by a Designating Lender and a designee
representing that it is a Designated Lender, the Administrative Agent will
accept such Designation Agreement and will give prompt notice thereof to the
Borrower, whereupon, (i) the Borrower shall execute and deliver to the
Designating Lender a Bid Rate Note payable to the order of the Designated
Lender, (ii) from and after the effective date specified in the Designation
Agreement, the Designated Lender shall become a party to this Agreement with a
right (subject to the provisions of Section 2.3) to make Money Market Loans on
behalf of its Designating Lender pursuant to Section 2.3 after the Borrower has
accepted a Money Market Loan (or portion thereof) of the Designating Lender and
subject to the terms of this Agreement, and (iii) the Designated Lender shall
not be required to make payments with respect to any obligations in this
Agreement except to the extent of excess cash flow of such Designated Lender
which is not otherwise required to repay obligations of such Designated Lender
which are then due and payable; provided, however, that regardless of such
designation and assumption by the Designated Lender, the Designating Lender
shall be and shall remain obligated to the Borrower, the Administrative Agent,
and the Banks for each and every of the obligations of the Designating Lender
and its related Designated Lender with respect to this Agreement, including,
without limitation, any indemnification obligations under Section 7.6 hereof and
any sums otherwise payable to the Borrower by the Designated Lender. Each
Designating Lender shall serve as the administrative agent of the Designated
Lender and shall on behalf of, and to the exclusion of, the Designated Lender:
(i) receive any and all payments made for the benefit of the Designated Lender
and (ii) give and receive all communications and notices and take all actions
hereunder, including, without limitation, votes, approvals, waivers, consents
and amendments under or relating to this Agreement and the other Loan Documents.
Any such notice communication, vote, approval, waiver, consent or amendment
shall be signed by the Designating Lender as administrative agent for the
Designated Lender and shall not be signed by the Designated Lender on its own
behalf and shall be binding upon the Designated Lender to the same extent as if
signed by the Designated Lender on its own behalf. The Borrower, the
Administrative Agent, and the Banks may rely thereon without any requirement
that the Designated Lender sign or acknowledge the same. No Designated Lender
may assign or transfer all or any portion of its interest hereunder or under any
other Loan Document, other than assignments to the Designating Lender which
originally designated such Designated Lender or otherwise in accordance with the
provisions of Section 9.6 (b) and (c), and any such assignment or transfer shall
be null and void.

          (e)  Any Bank may at any time assign all or any portion of its rights
under this Agreement and its Notes and the Letter(s) of Credit participated in
by such Bank or, in the case of the 

                                       91
<PAGE>
 
Fronting Bank, issued by it, to a Federal Reserve Bank. No such assignment shall
release the transferor Bank from its obligations hereunder.

          (f)  Administrative Agent shall maintain, at its address referred to
on Schedule II, a copy of each Assignment and Assumption Agreement delivered to
and accepted by it and shall record in its records the names and addresses of
each Bank and the Commitment of, and principal amount of the Loans owing to,
such Bank from time to time. Borrower and Banks may treat each Person whose name
is recorded in the Administrative Agent's records as a Bank hereunder for all
purposes of this Agreement.

          (g)  Borrower will use reasonable efforts to cooperate with the
Administrative Agent and Banks in connection with the assignment of interests
under this Agreement or the sale of participations herein.

     SECTION 9.7.   Collateral.
                    ---------- 

     Each of the Banks represents to the Administrative Agent and each of the
other Banks that it in good faith is not relying upon any Margin Stock as
collateral in the extension or maintenance of the credit provided for in this
Agreement.

and other similar documents as may be necessary to release the collateral held
by the Administrative Agent pursuant to the Existing Agreement and shall cause
all of the promissory notes held by the lenders under the Existing Agreement to
be returned to the Borrower.

     SECTION 9.10.  WAIVER OF JURY TRIAL.
                    -------------------- 

     THE BORROWER, THE ADMINISTRATIVE AGENT AND THE BANKS WAIVE THE RIGHT TO A

                    -------- 

     All indemnities set forth herein shall survive the execution and delivery
of this Agreement and the other Loan Documents and the making and repayment of
the Loans hereunder.

     SECTION 9.12.  Domicile of Loans.
                    ----------------- 

     Each Bank may transfer and carry its Loans at, to or for the account of any
domestic or foreign branch office, subsidiary or affiliate of such Bank.

     SECTION 9.13.  Limitation of Liability.
                    ----------------------- 

     No claim may be made by the Borrower or any other Person acting by or

for any consequential or punitive damages in respect of any claim for breach of
contract or any other theory of liability arising out of or related to the
transactions contemplated by this Agreement or by the other Loan Documents, or
any act, omission or event occurring in connection therewith; and the Borrower
hereby waives, releases and agrees not to sue upon any claim for any such
damages, whether or not accrued and whether or not known or suspected to exist
in its favor.

     SECTION 9.14.  Recourse Obligation.
                    ------------------- 

     (a)  This Agreement and the Obligations hereunder are fully recourse to the
Borrower. Notwithstanding the foregoing, no recourse under or upon any
obligation, covenant, or agreement contained in this Agreement shall be had
against any officer, director, shareholder or employee of the Borrower or CESRRI
except in the event of fraud or misappropriation of funds on the part of such
officer, director, shareholder or employee.

     (b)  Subject to the exceptions and qualifications set forth hereinbelow,
the general and limited partners of Borrower and any Consolidated Subsidiary
shall not be personally liable for the payment of the Obligations of the
Borrower and any Consolidated Subsidiary respectively, and any judgment or
decree in any action brought to enforce any Obligation shall be enforceable only
against the Borrower and any Consolidated Subsidiary and the assets of Borrower
and any Consolidated Subsidiary, and any such judgment or decree shall not be
subject to execution upon or be a lien upon the assets of the general or limited
partners of the Borrower other than their respective partnership interests in
Borrower and any Consolidated Subsidiary. Notwithstanding the foregoing, the
general partner of Borrower shall be fully and personally liable as general
partner for the following:

               (i)  the commission of fraud by the Borrower or any material
misrepresentation made by the Borrower in connection with, arising out of, or in
any way related or 

                                       94
<PAGE>
 
incidental to the application for or closing of this Agreement, the Notes or any
advance made thereunder, or any of the Loan Documents executed or delivered in
connection herewith or the transactions related hereto or thereto; and

               (ii) any fraudulent conveyance made by Borrower, CESRRI or any
Subsidiary.

     Nothing contained herein shall affect, reduce or otherwise limit the
obligations of  any Consolidated Subsidiary on the Guaranty furnished by any
such party.

     SECTION 9.15.  Confidentiality.
                    --------------- 

     The Administrative Agent, and each Bank shall use reasonable efforts to
assure that information about Borrower, CESRRI and its Subsidiaries and
Investments Affiliates, and the Properties thereof and their operations, affairs
and financial condition, not generally disclosed to the public, which is
furnished to Administrative Agent, or any Bank pursuant to the provisions hereof
or any other Loan Document is used only for the purposes of this Agreement and
shall not be divulged to any Person other than the Administrative Agent, the
Banks, and their affiliates and respective officers, directors, employees and
agents who are actively and directly participating in the evaluation,
administration or enforcement of the Loan, except: (a) to their attorneys and
accountants, (b) in connection with the enforcement of the rights and exercise
of any remedies of the Administrative Agent, and the Banks hereunder and under
the other Loan Documents, (c) in connection with assignments and participations
and the solicitation of prospective assignees and participants referred to in
Section 9.6 hereof, and (d) as may otherwise be required or requested by any
regulatory authority having jurisdiction over the Administrative Agent, or any
Bank or by any applicable law, rule, regulation or judicial process.

     SECTION 9.16.  Bank's Failure to Fund.
                    ---------------------- 

          (a)  Unless the Administrative Agent shall have received notice from a
Bank prior to the date of any Borrowing that such Bank will not make available
to the Administrative Agent such Bank's share of such Borrowing, the
Administrative Agent may assume that such Bank has made such share available to
the Administrative Agent on the date of such Borrowing in accordance with
Section 2.4(b) or Section 2.16(e) hereof, and the Administrative Agent may, in
reliance upon such assumption, make available to Borrower on such date a
corresponding amount. If and to the extent that such Bank shall not have so made
such share available to the Administrative Agent, such Bank and Borrower
severally agree to repay to the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, in accordance with the
provisions of Section 2.4(c) or Section 2.16(e) hereof. If such Bank shall repay
to the Administrative Agent such corresponding amount, such amount so repaid
shall constitute such Bank's Loan included in such Borrowing for purposes of
this Agreement. Nothing contained in this Section 9.16(a) or Sections 2.4(c) or
2.16(e), shall he deemed to reduce the Commitment of any Bank or in any way
affect the rights of Borrower with respect to any defaulting Bank or
Administrative Agent. The failure of any Bank to make available to the
Administrative Agent such Bank's share of any Borrowing in accordance with
Sections 2.4(b) or 2.16(e) hereof shall not relieve any other Bank of its
obligations

                                       95
<PAGE>
 
to fund its Commitment, in accordance with the provisions hereof.

          (b)  If a Bank does not advance to Administrative Agent such Bank's
pro rata share of a Loan in accordance herewith, then neither Administrative
Agent, nor the other Banks shall be required or obligated to fund such Bank's
pro rata share of such Loan.

          (c)  As used herein, the following terms shall have the meanings set
forth below:

               (i)    "Defaulting Bank" shall mean any Bank which (x) does not
                       ---------------
advance to the Administrative Agent such Bank's pro rata share of a Loan in
accordance herewith for a period of five (5) Domestic Business Days after notice
of such failure from Administrative Agent, (y) shall otherwise fail to perform
such Bank's obligations under the Loan Documents for a period of five (5)
Domestic Business Days after notice of such failure from Administrative Agent,
or (z) shall fail to pay the Administrative Agent, or any other Bank, as the
case may be, upon demand, such Bank's pro rata share of any costs, expenses or
disbursements incurred or made by the Administrative Agent pursuant to the terms
of the Loan Documents for a period of five (5) Domestic Business Days after
notice of such failure from Administrative Agent, and in all cases, such failure
is not as a result of a good faith dispute as to whether such advance is
properly required to be made pursuant to the provisions of this Agreement, or as
to whether such other performance or payment is properly required pursuant to
the provisions of this Agreement.

               (ii)   "Junior Creditor" means any Defaulting Bank which has not
                       --------------
(x) fully cured each and every default on its part under the Loan Documents and
(y) unconditionally tendered to the Administrative Agent such Defaulting Bank's
pro rata share of all costs, expenses and disbursements required to be paid or
reimbursed pursuant to the terms of the Loan Documents.

               (iii)  "Payment in Full" means, as of any date, the receipt by
                       ---------------                                       
the Banks who are not Junior Creditors of an amount of cash, in lawful currency
of the United States, sufficient to indefeasibly pay in full all Senior Debt.

               (iv)   "Senior Debt" means (x) collectively, any and all
                       -----------  
indebtedness, obligations and liabilities of the Borrower to the Banks who are
not Junior Creditors from time to time, whether fixed or contingent, direct or
indirect, joint or several, due or not due, liquidated or unliquidated,
determined or undetermined, arising by contract, operation of law or otherwise,
whether on open account or evidenced by one or more instruments, and whether for
principal, premium, interest (including, without limitation, interest accruing
after the filing of a petition initiating any proceeding referred to in Section
6.1(f) or (g)), reimbursement for fees, indemnities, costs, expenses or
otherwise, which arise under, in connection with or in respect of the Loans or
the Loan Documents, and (y) any and all deferrals, renewals, extensions and
refundings of, or amendments, restatements, rearrangements, modifications or
supplements to, any such indebtedness, obligation or liability.

               (v)    "Subordinated Debt" means (x) any and all indebtedness,
                       -----------------                                     
obligations and liabilities of Borrower to one or more Junior Creditors from
time to time, whether fixed or contingent, direct or indirect, joint or several,
due or not due, liquidated or unliquidated, determined or undetermined, arising
by contract, operation of law or otherwise, whether on open account or 

                                       96
<PAGE>
 
evidenced by one or more instruments, and whether for principal, premium,
interest (including, without limitation, interest accruing after the filing of a
petition initiating any proceeding referred to in Section 6.1(f) or (g)),
reimbursement for fees, indemnities, costs, expenses or otherwise, which arise
under, in connection with or in respect of the Loans or the Loan Documents, and
(y) any and all deferrals, renewals, extensions and refundings of, or
amendments, restatements, rearrangements, modifications or supplements to, any
such indebtedness, obligation or liability.

          (d)  Immediately upon a Bank's becoming a Junior Creditor, no Junior
Creditor shall, prior to Payment in Full of all Senior Debt:

               (i)    accelerate, demand payment of, sue upon, collect, or
receive any payment upon, in any manner, or satisfy or otherwise discharge, any
Subordinated Debt, whether for principal, interest and otherwise;

               (ii)   take or enforce any Liens to secure Subordinated Debt or
attach or levy upon any assets of Borrower, to enforce any Subordinated Debt;

               (iii)  enforce or apply any security for any Subordinated Debt;
or

               (iv)   incur any debt or liability, or the like, to, or receive
any loan, return of capital, advance, gift or any other property, from, the
Borrower.

          (e)  In the event of:

               (i)    any insolvency, bankruptcy, receivership, liquidation,
dissolution, reorganization, readjustment, composition or other similar
proceeding relating to Borrower;

               (ii)   any liquidation, dissolution or other winding-up of the
Borrower, voluntary or involuntary, whether or not involving insolvency,
reorganization or bankruptcy proceedings;

               (iii)  any assignment by the Borrower for the benefit of
creditors;

               (iv)   any sale or other transfer of all or substantially all
assets of the Borrower; or

               (v)    any other marshalling of the assets of the Borrower;

each of the Banks shall first have received Payment in Full of all Senior Debt
before any payment or distribution, whether in cash, securities or other
property, shall be made in respect of or upon any Subordinated Debt.  Any
payment or distribution, whether in cash, securities or other property that
would otherwise be payable or deliverable in respect of Subordinated Debt to any
Junior Creditor but for this Agreement shall be paid or delivered directly to
the Administrative Agent for distribution to the Banks in accordance with this
Agreement until Payment in Full of all Senior Debt.  If any Junior Creditor
receives any such payment or distribution, it shall promptly pay over or deliver
the same to 

                                       97
<PAGE>
 
the Administrative Agent for application in accordance with the preceding
sentence.

          (f)  Each Junior Creditor shall file in any bankruptcy or other
proceeding of Borrower in which the filing of claims is required by law, all
claims relating to Subordinated Debt that such Junior Creditor may have against
Borrower and assign to the Banks who are not Junior Creditors all rights of such
Junior Creditor thereunder.  If such Junior Creditor does not file any such
claim prior to forty-five (45) days before the expiration of the time to file
such claim, Administrative Agent, as attorney-in-fact for such Junior Creditor,
is hereby irrevocably authorized to do so in the name of such Junior Creditor
or, in Administrative Agent's sole discretion, to assign the claim to a nominee
and to cause proof of claim to be filed in the name of such nominee.  The
foregoing power of attorney is coupled with an interest and cannot be revoked.
The Administrative Agent shall, to the exclusion of each Junior Creditor, have
the sole right, subject to Section 9.5 hereof, to accept or reject any plan
proposed in any such proceeding and to take any other action that a party filing
a claim is entitled to take.  In all such cases, whether in administration,
bankruptcy or otherwise, the Person or Persons authorized to pay such claim
shall pay to Administrative Agent the amount payable on such claim and, to the
full extent necessary for that purpose, each Junior Creditor hereby transfers
and assigns to the Administrative Agent all of the Junior Creditor's rights to
any such payments or distributions to which Junior Creditor would otherwise be
entitled.

          (g)  (i)  If any payment or distribution of any character or any
security, whether in cash, securities or other property, shall be received by
any Junior Creditor in contravention of any of the terms hereof, such payment or
distribution or security shall be received in trust for the benefit of, and
shall promptly be paid over or delivered and transferred to, Administrative
Agent for application to the payment of all Senior Debt, to the extent necessary
to achieve Payment in Full.  In the event of the failure of any Junior Creditor
to endorse or assign any such payment, distribution or security, Administrative
Agent is hereby irrevocably authorized to endorse or assign the same as
attorney-in-fact for such Junior Creditor.

               (ii) Each Junior Creditor shall take such action (including,
without limitation, the execution and filing of a financing statement with
respect to this Agreement and the execution, verification, delivery and filing
of proofs of claim, consents, assignments or other instructions that
Administrative Agent may require from time to time in order to prove or realize
upon any rights or claims pertaining to Subordinated Debt or to effectuate the
full benefit of the subordination contained herein) as may, in Administrative
Agent's sole and absolute discretion, be necessary or desirable to assure the
effectiveness of the subordination effected by this Agreement.

          (h)  (i)  Each Bank that becomes a Junior Creditor understands and
acknowledges by its execution hereof that each other Bank is entering into this
Agreement and the Loan Documents in reliance upon the absolute subordination in
right of payment and in time of payment of Subordinated Debt to Senior Debt as
set forth herein.

               (ii) Only upon the Payment in Full of all Senior Debt shall any
Junior Creditor be subrogated to any remaining rights of the Banks which are not
Defaulting Banks to receive payments or distributions of assets of the Borrower
made on or applicable to any Senior Debt.

                                       98
<PAGE>
 
               (iii)  Each Junior Creditor agrees that it will deliver all
instruments or other writings evidencing any Subordinated Debt held by it to
Administrative Agent, promptly after request therefor by the Administrative
Agent.

               (iv)   No Junior Creditor may at any time sell, assign or
otherwise transfer any Subordinated Debt, or any portion thereof, including,
without limitation, the granting of any Lien thereon, unless and until
satisfaction of the requirements of Section 9.6 above and the proposed
transferee shall have assumed in writing the obligation of the Junior Creditor
to the Banks under this Agreement, in a form acceptable to the Administrative
Agent.

               (v)    If any of the Senior Debt should be invalidated, avoided
or set aside, the subordination provided for herein nevertheless shall continue
in full force and effect and, as between the Banks which are not Defaulting
Banks and all Junior Creditors, shall be and be deemed to remain in full force
and effect.

               (vi)   Each Junior Creditor hereby irrevocably waives, in respect
of Subordinated Debt, all rights (x) under Sections 361 through 365, 502(e) and
509 of the Bankruptcy Code (or any similar sections hereafter in effect under
any other Federal or state laws or legal or equitable principles relating to
bankruptcy, insolvency, reorganizations, liquidations or otherwise for the
relief of debtors or protection of creditors), and (y) to seek or obtain
conversion to a different type of proceeding or to seek or obtain dismissal of a
proceeding, in each case in relation to a bankruptcy, reorganization, insolvency
or other proceeding under similar laws with respect to the Borrower. Without
limiting the generality of the foregoing, each Junior Creditor hereby
specifically waives (A) the right to seek to give credit (secured or otherwise)
to the Borrower in any way under Section 364 of the Bankruptcy Code unless the
same is subordinated in all respects to Senior Debt in a manner acceptable to
Administrative Agent in its sole and absolute discretion and (B) the right to
receive any collateral security (including any "super priority" or equal or
"priming" or replacement Lien) for any Subordinated Debt unless the Banks which
are not Defaulting Banks have received a senior position acceptable to the Banks
in their sole and absolute discretion to secure all Senior Debt (in the same
collateral to the extent collateral is involved).

          (i)  (i)    In addition to and not in limitation of the subordination
effected by this Section 9.16, the Administrative Agent and each of the Banks
which are not Defaulting Banks may in their respective sole and absolute
discretion, also exercise any and all other rights and remedies available at law
or in equity in respect of a Defaulting Bank; and

               (ii)   The Administrative Agent shall give each of the Banks
notice of the occurrence of a default under this Section 9.16 by a Defaulting
Bank and if the Administrative Agent and/or one or more of the other Banks
shall, at their option, fund any amounts required to be paid or advanced by a
Defaulting Bank, the other Banks who have elected not to fund any portion of
such amounts shall not be liable for any reimbursements to the Administrative
Agent and/or to such other funding Banks.

          (j)  Notwithstanding anything to the contrary contained or implied
herein, a Defaulting Bank shall not be entitled to vote on any matter as to
which a vote by the Banks is required 

                                       99

hereunder, including, without limitation, any actions or consents on the part of
the Administrative Agent as to which the approval or consent of all the Banks or
the Required Banks is required under Article VIII, Section 9.5 or elsewhere, so
long as such Bank is a Defaulting Bank; provided, however, that in the case of
any vote requiring the unanimous consent of the Banks, if all the Banks other
than the Defaulting Bank shall have voted in accordance with each other, then
the Defaulting Bank shall be deemed to have voted in accordance with such Banks.

          (k)  Each of the Administrative Agent and any one or more of the Banks
which are not Defaulting Banks may, at their respective option, (i) advance to
the Borrower such Bank's pro rata share of the Loans not advanced by a
Defaulting Bank in accordance with the Loan Documents, or (ii) pay to the
Administrative Agent such Bank's pro rata share of any costs, expenses or
disbursements incurred or made by the Administrative Agent pursuant to the terms
of this Agreement not theretofore paid by a Defaulting Bank. Immediately upon
the making of any such advance by the Administrative Agent or any one of the
Banks, such Bank's pro rata share and the pro rata share of the Defaulting Bank
shall be recalculated to reflect such advance. All payments, repayments and
other disbursements of funds by the Administrative Agent to Banks shall
thereupon and, at all times thereafter be made in accordance with such Bank's
recalculated pro rata share unless and until a Defaulting Bank shall fully cure
all defaults on the part of such Defaulting Bank under the Loan Documents or
otherwise existing in respect of the Loans or this Agreement, at which time the
pro rata share of the Bank(s) which advanced sums on behalf of the Defaulting
Bank and of the Defaulting Bank shall be restored to their original percentages.

     SECTION 9.17.  No Bankruptcy Proceedings.
                    ------------------------- 

     Each of the Borrower, the Banks and the Administrative Agent hereby agrees
that it will not institute against any Designated Lender or join any other
Person in instituting against any Designated Lender any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceeding under any
federal or state bankruptcy or similar law, until one year and one day after the
later to occur of (i) the payment in full of the latest maturing commercial
paper note issued by such Designated Lender and (ii) the later to occur of (a)
the payment in full of the Obligations or (b) the Maturity Date.
