ITEM 1.  BUSINESS

BACKGROUND AND GENERAL

     We are a  fully-integrated  real estate investment  company organized under
Maryland law, providing property management,  leasing,  marketing,  acquisition,
development, redevelopment, construction, finance and other related services. We
have elected to be taxed as a Real Estate  Investment Trust ("REIT") for federal
income tax purposes  beginning  with our taxable period ended December 31, 1997.
As  of  December  31,  1998,  we  owned  24  office  properties,  46  industrial
properties,  one retail  center and one parking  facility.  Our  properties  are
located  primarily  in the Chicago  metropolitan  area.  In  addition,  we own a
mortgage  on an office  property  located  at 180 N.  LaSalle  Street,  Chicago,
Illinois.

     We also own  approximately  225.0 acres of land that we may  develop.  This
acreage includes a development site which contains  approximately  67,000 square
feet  located in the Chicago  central  business  district and is held by a joint
venture with a third party. We also have rights to acquire  approximately  325.8
acres of developable land,  including rights to acquire two sites located in the
Chicago central business district containing  approximately 119,000 square feet.
We believe that this land could be developed to have  approximately  4.7 million
square  feet of  additional  office  space and over 7.6  million  square feet of
additional industrial space.

     We were formed on July 21, 1997 as a Maryland real estate  investment trust
to succeed  and expand the office and  industrial  real  estate  business of The
Prime Group, Inc. ("PGI"),  which was our predecessor.  On November 17, 1997, we
sold  12,380,000  of our  common  shares  at a price of  $20.00  per share in an
underwritten  offering and became a public  company.  Our executive  offices are
located at 77 West Wacker Drive,  Suite 3900,  Chicago,  Illinois 60601, and our
telephone number is (312) 917-1300.

     We are the managing  general  partner of, and  currently  hold 59.4% of the
economic interests in, Prime Group Realty, L.P., our operating  partnership.  We
conduct  substantially  all of our business through this operating  partnership,
except for leasing,  corporate advisory,  construction,  architectural and third
party property  management  services and land sales, which are conducted through
Prime Group Realty  Services,  Inc., a Maryland  corporation  and its affiliates
(the "Services Company").

TAX STATUS

     We have elected to be taxed as a REIT under Sections 856 through 860 of the
Internal Revenue Code of 1986, as amended.  As a REIT, we will not be subject to
federal  income  tax at the  corporate  level on  income  we  distribute  to our
shareholders  as  long as we  distribute  at  least  95% of our  taxable  income
(excluding any net capital gain) each year. Since our inception, we believe that
we have complied  with the tax  regulations  to maintain our REIT status.  If we
fail to qualify  as a REIT in any  taxable  year,  we will be subject to federal
income tax  (including any  applicable  alternative  minimum tax) on our taxable
income at regular  corporate  rates.  Even if we  qualify  as a REIT,  we may be
subject to certain state and local taxes on our income and property.

BUSINESS AND GROWTH STRATEGIES

     Our  primary  business  strategy is to achieve  our  investment  and growth
objectives by focusing on the  acquisition,  development and operation of office
and industrial  real estate located in the Chicago  metropolitan  area and, to a
lesser extent,  other midwestern markets. To implement this strategy,  we intend
to continue to:

     -    own, acquire,  develop,  redevelop,  lease, manage and operate Class A
          office buildings that have below market rents and, therefore,  provide
          the opportunity to enhance returns as leases expire or are renewed;

     -    develop Class A office  buildings in prime locations with  significant
          leasing potential;

     -    acquire distressed,  under-performing and under-managed Class B office
          buildings in desirable  locations and improve the income  potential of
          such assets by raising  them to a higher  operating  standard  through
          value-added renovation programs,  professional property management and
          aggressive leasing, retenanting and marketing efforts;


                                      -2-
<PAGE>
     -    acquire and develop  properties that underutilize  their sites or that
          have  excess  land for future  development; 

     -    acquire  properties or portfolios  of  properties  from  tax-sensitive
          owners where the properties  can be acquired on a  tax-deferred  basis
          using  common  units of limited  partner  interests  in our  operating
          partnership, as purchase consideration; and

     -    own,  acquire,  develop,  redevelop,  lease,  manage and operate  bulk
          warehouse/distribution  facilities  and  overhead  crane/manufacturing
          facilities.

     Class A office buildings are centrally located,  professionally managed and
maintained, attract high-quality tenants and command upper-tier rental rates and
are modern  structures or have been modernized to compete with newer  buildings.
Class B office  buildings have good location,  construction  and tenancy and are
sometimes  considered  to be  competitive  with the  lower  spectrum  of Class A
buildings.

     We believe that we can draw upon our  extensive  experience  and  long-term
presence in the Chicago  metropolitan  area to create a strategic  advantage  in
competing for future development and acquisition opportunities.

     OPERATING STRATEGY. We will focus on enhancing our cash flow per share by:

     -    engaging  in  pro-active   leasing  programs  and  effective  property
          management;

     -    managing  operating  expenses  through the use of in-house  management
          expertise;

     -    maintaining  and  developing  long-term  relationships  with a diverse
          tenant  group;

     -    attracting and retaining  motivated  employees by providing  financial
          and other incentives;

     -    continuing to emphasize  value-added  capital  improvements to enhance
          our properties' competitive advantages in their submarkets; and

     -    maximizing the cash flow of our properties.

     ACQUISITION  STRATEGY.  We plan to  increase  our cash  flow  per  share by
acquiring  additional  office and industrial  properties,  including  properties
that:

     -    provide attractive initial yields and significant potential for growth
          in cash flow from property operations;

     -    are well-located,  of high quality and competitive in their respective
          submarkets;

     -    are  located  in our  existing  submarkets  and/or in other  strategic
          submarkets  where the demand for office and  industrial  space exceeds
          available supply; and

     -    have  been   under-managed  or  are  otherwise   capable  of  improved
          performance through intensive management, marketing and leasing.

     We  plan  to  concentrate  our   acquisition   activities  in  the  Chicago
metropolitan  area and, to a lesser  extent,  in other  midwestern  markets.  We
believe that  attractive  opportunities  exist to acquire  office and industrial
properties in these markets at prices below  replacement  cost. Each acquisition
opportunity  will be reviewed  to  evaluate  whether it meets one or more of the
following criteria:

     -    potential  for higher  occupancy  levels  and/or  rents as well as for
          lower tenant turnover and/or operating expenses;

     -    ability to generate  returns in excess of our weighted average cost of
          capital,  taking into  account the  estimated  costs  associated  with
          renovation and tenant turnover (i.e.,  tenant improvements and leasing
          commissions);  and

     -    purchase prices at or below estimated replacement cost.



                                      -3-
<PAGE>
     We believe we have certain competitive  advantages that enhance our ability
to  identify  and  complete  acquisitions  on  a  timely  and  efficient  basis,
including:

     -    our  management's   significant  local  market  experience  with,  and
          knowledge of, properties, submarkets and potential tenants;

     -    our  management's  long-standing  relationships  with  commercial real
          estate brokers and  institutional  and other owners of commercial real
          estate in the Chicago metropolitan area;

     -    our fully-integrated real estate operations, which allow us to quickly
          evaluate and respond to  acquisition  opportunities;

     -    our  ability  to access  relatively  low-cost  financing  through  the
          capital  markets; 

     -    our management's  reputation as an experienced purchaser of office and
          industrial  properties with the ability to execute  transactions in an
          efficient and timely manner; and

     -    our ability to add a number of office and industrial properties to our
          portfolio  without the need for a significant  increase in general and
          administrative expenses, due to our expertise and depth of management.

     We also plan to make strategic  purchases of land where opportunities exist
for current or future development.

     We believe  that many of the owners of  commercial  real estate  properties
located  in  the  Chicago  metropolitan  area  have a low  tax  basis  in  their
properties  and  have  the  corresponding   potential  for  the  recognition  of
substantial taxable gains as a result of the disposition of such properties.  We
believe that our capital structure and ability to acquire properties in exchange
for common units,  and thereby  defer a seller's  potential  taxable gain,  will
enhance our ability to  consummate  transactions  quickly and to structure  more
competitive  acquisitions  than other real estate  companies in the market which
lack our access to capital and ability to acquire property with common units.

     DEVELOPMENT  STRATEGY.  As opportunities  arise and where market conditions
support a  favorable  risk-adjusted  return on  investment,  we intend to pursue
opportunities  for growth  through the  development of new office and industrial
properties. We believe that the strength and experience of our management in the
development  of  office  and  industrial  properties  will  provide  us  with  a
competitive  advantage  in  evaluating  and  pursuing  opportunities  to develop
additional  properties.  During the next few years,  we expect  that most of our
development  activities  will be focused on Chicago  central  business  district
office and suburban office and industrial properties in the Chicago metropolitan
area.

     Based on ongoing  marketing  activities and  discussions  with  prospective
tenants,  we expect that over the next several  years there will be  significant
demand  from  several  large  tenants  that are unable to find  large  blocks of
contiguous  Class A office  space in downtown  Chicago  which may lead to office
development  opportunities.  We believe that our  significant  land holdings and
land option  rights will provide us with a distinct  advantage in competing  for
future development opportunities.

     The Services Company's corporate advisory activities with third parties are
expected  to give us  further  access to future  development  opportunities  for
properties we will build and lease.  The Services  Company will also continue to
undertake build-to-suit projects for sale to third parties.

     FINANCING STRATEGY.  During 1998, our Board Trustees modified our financing
policy to specify that we intend to operate with a ratio of debt-to-total market
capitalization at a level below 50.0%.

     Our  Board  further  modified  our  financing  policy in  December  1998 by
replacing the debt-to-total market  capitalization  formulation with a series of
financial  ratios and other  measurements  which would  better  measure our debt
carrying  capacity.  As modified,  our new  financing  policy has the  following
targets in place as of December 31, 1998: (i) a minimum interest  coverage ratio
of at least 2.0,  (ii) a minimum fixed  coverage  charge ratio of at least 1.60,
(iii)  a ratio  of  debt-to-net  asset  value  of no more  than  50%,  and  (iv)
unencumbered  cash and credit  availability of at least $40.0 million,  of which
$10.0 million  should be cash on hand.  The  foregoing  ratios and  measures are
calculated  pursuant  to  detailed  definitions  set by our Board  and,  in some
instances, are adjusted over time pursuant to a schedule set by our Board.

                                       -4-
<PAGE>
     The above  targets  do not mean  that we will  operate  within  each of the
ratios at all time or that our Board will not approve  actions  which will cause
us to not be in compliance with this policy. Our financing policy may be altered
without the consent of our shareholders, and our organizational documents do not
limit the amount or type of indebtedness that we may incur.

     We intend to use one or more sources of capital for future acquisitions and
development  activities.  These capital sources may include  undistributed  cash
flow, borrowings under certain credit facilities, property specific non-recourse
debt,  proceeds from the issuance of long-term,  tax-exempt bonds and other debt
or equity securities and other bank and/or institutional borrowings.

     During 1998, we acquired the following eight office properties:

     The Aurora land contracts  require us to purchase an additional 132.7 acres
over a three to five year period for additional  consideration of $10.4 million.
Certain  minimum  installment  payments  are  required;  however,  the timing of
purchases is at our discretion.  During 1998, we made two  installment  payments
totaling $0.4 million.

     In July 1998, we began  construction  of a 242,000  square foot  industrial
facility and in September 1998, we began  construction of four office  buildings
with a total of 180,000  square feet on the  Libertyville  land  parcels  listed
above.

     Concurrently with the closing of our initial public offering, we obtained a
secured revolving credit facility from a group of financial  institutions with a
maximum  commitment  of $235.0  million.  We used the  credit  facility  to fund
property acquisitions and letters-of-credit  that provide credit enhancements on
certain of our bonds  payable.  The credit  facility is also  subject to various
financial and other  operating  covenants.  During 1998, the credit facility was
amended to provide that the commitments  under the credit facility be reduced to
$80.0  million  and the  interest  rate was  modified  from LIBOR plus 150 basis
points to LIBOR plus 225 basis points.  On February 4, 1999, the credit facility
was further  amended and the  commitment  was reduced to $75.0  million with the
interest rate remaining the same.

     On  January  1, 1998,  we  provided  the  Services  Company a $5.0  million
line-of-credit,  which (i)  accrues  interest  at LIBOR plus 3%,  (ii)  requires
monthly  principal and interest  payments from  available cash flow, as defined,
and (iii)  matures on  December  31,  2000.  The line is  collateralized  by the
Services  Company's third party receivables and is subject to various covenants.
As of December 31, 1998, the line-of-credit had $0.6 million outstanding.

     In January 1998, we obtained a $15.0 million revolving  line-of-credit with
a financial  institution.  The line-of-credit is collateralized by an industrial
property  located at as 475  Superior  Avenue in Munster,  Indiana.  Outstanding
balances  under the  line-of-credit  bear interest at a rate equal to LIBOR plus
195 basis  points.  In  January  1999,  we  exercised  an  option to extend  the
line-of-credit for one year to January 2000, with the existing terms and subject
to an  additional  one-year  extension at our option.  Generally,  the covenants
contained in the line-of-credit are identical to the covenants  contained in the
above  mentioned  credit  facility.  The $15.0  million  line-of-credit  and the
previously mentioned $75.0 million credit facility are collectively  referred to
as the "Credit Facilities."

     During 1998, we obtained the following new mortgage indebtedness:

     We used a portion of the proceeds  from the mortgage  notes listed above to
purchase the above  properties,  repay previously  outstanding  mortgage debt of
$83.5 million, and reduce borrowings under the Credit Facilities.

     In February  1998, we refinanced  $48.8 million of  letters-of-credit  that
provided  credit  enhancements  on certain of our bonds  payable from one of our
Credit  Facilities  to a separate  financing  facility  provided  by a financial


                                      -6-
<PAGE>
institution.  The new  letters-of-credit  have an annual fee of 1.4% of the face
amount and are  collateralized  by  mortgages on certain  industrial  and office
properties and a $5.0 million cash collateral account.  This amount was included
in restricted cash escrows at December 31, 1998.

     On  March  30,  1998,  we  entered  into  a  joint  venture  that  acquired
approximately  67,000 square feet of vacant land located in the Chicago  central
business  district.  The parcel was acquired for the potential  development of a
Class A multi-purpose  facility,  with  approximately  1,000,000  square feet of
office space,  approximately  100,000  square feet of retail space and a parking
garage with a capacity for  approximately  250 cars. We have economic control of
the joint venture and, therefore,  have consolidated the operations of the joint
venture from the date of inception.  The joint venture  entered into a bank loan
in the amount of $13.5 million to acquire the land.  Interest is payable monthly
at a rate of LIBOR plus 200 basis points or at the lender's prime rate. The note
was to mature on April 1, 1999; however we have exercised a six-month  extension
option and extended the maturity to October 1, 1999.

     On March 25,  1998,  we  completed a private  placement of 2,579,994 of our
common  shares  to   institutional   investors  and  received  net  proceeds  of
approximately  $45.9  million,  which were used to fund the  acquisition  of the
office  properties  located at 208 South LaSalle  Street and 122 South  Michigan
Avenue.

     On March 31, 1998 and on September  28,  1998,  we issued a total of 22,500
common shares  granted to two of our officers and 2,500 common shares granted to
one of our board members pursuant to their  employment  agreements or consulting
agreement, as applicable.

     On June 5, 1998, we completed the sale of 4.0 million  shares of our Series
B -  Cumulative  Redeemable  Preferred  Shares  and  received  net  proceeds  of
approximately  $95.3 million which were used to fund (i) the  acquisition of Two
Century  Centre and 2000 York Road, and (ii) repay  borrowings  under the Credit
Facilities.  Distributions  on the Series B -  Redeemable  Preferred  Shares are
payable  quarterly on or about the last day of January,  April, July and October
of each year,  at the rate of 9%  (equivalent  to $2.25 per annum per Series B -
Cumulative  Redeemable  Preferred Share).  The Series B - Cumulative  Redeemable
Preferred Shares rank senior to our common shares and our Series A - Convertible
Preferred  Shares as to the payment of dividends and as to the  distribution  of
assets.  On and  after  June 5,  2003,  the  Series  B -  Cumulative  Redeemable
Preferred  Shares may be redeemed at our option at a redemption  price of $25.00
per share plus accrued and unpaid distributions. The redemption price is payable
solely  out of the  proceeds  from  the  sale of our  other  capital  shares  of
beneficial interest.

     On July 22, 1998, we entered into a purchase  agreement,  with an affiliate
of an investor in the operating  partnership,  to acquire two office  buildings,
IBM Plaza (a  1,354,354  square  foot  office  building  located in the  Chicago
central  business  district)  and  National  City Center (a 766,965  square foot
office building located in Cleveland,  Ohio) for an aggregate  purchase price of
approximately  $357.0 million. On September 15, 1998, we terminated the purchase
agreement in accordance  with the terms of the agreement due to the failure of a
material condition precedent to the closing of these acquisitions.  On September
21,  1998,  the sellers  notified  us in writing  that they  believed  they were
entitled to the $20.0 million  earnest money provided for by the agreement,  and
instructed  the earnest  money  escrow  agent to draw the full amount  under two
earnest money  letters-of-credit we provided under one of the Credit Facilities.
The  sellers  also filed a complaint  against us with the  Supreme  Court of New
York,  New York County  alleging that we breached the  contract.  On October 30,
1998, we filed our answer to the  complaint and denied all material  allegations
of the complaint. We also filed a counterclaim against the sellers alleging that
the sellers  breached the contract and sought the return of the above  mentioned
earnest money and other damages.

     On February 5, 1999, we entered into an amended  option  agreement with the
seller  of IBM  Plaza  and an  amended  purchase  agreement  with the  seller of
National City Center, which have the following terms:

     -    both the  original  lawsuit  filed by the sellers and our counterclaim
          were dismissed;

     -    we purchased  National  City Center on February 5, 1999 for a contract
          price of $100.0 million; and

     -    the $20.0 million  earnest money escrow  described  above was released
          and  credited  to the  purchase  of  National  City Center and an $8.0
          million  nonrefundable  payment for the option to purchase  IBM Plaza.

                                      -7-
<PAGE>
          The option  provides us with the opportunity to purchase IBM Plaza for
          $230.0  million  (exclusive  of the $8.0 million  deposit) and expires
          October 31,  1999.  If the option is  exercised,  the  purchase of the
          property must be completed no later than December 20, 1999.

     On August 21, 1998, we entered into two treasury lock  agreements  with two
financial  institutions to lock certain debt instruments at the interest rate on
ten-year  Treasury  Notes  effective  on the date of the  agreements  to provide
interest rate protection on future debt financings.  One of these agreements was
entered into in  anticipation  of a planned  future  securitization  of a $170.0
million loan related to the 77 West Wacker Drive  building,  and had a lock rate
of 5.364%.  The other  agreement  was  entered  into in  anticipation  of $160.0
million in debt  related  to the  acquisition  of IBM Plaza,  had a lock rate of
4.732% and was to expire on March 19, 1999.  We made deposits as required by the
agreements,  totaling  approximately  $14.6  million at December  31, 1998 ($5.9
million related to the $170.0 million  agreement and $8.7 million related to the
$160.0  million  agreement),  exclusive  of  a  $2.0  million  credit  threshold
described below and are included in other assets in our  consolidated  financial
statements. The $170.0 million agreement was to expire on February 18, 1999, but
was  extended to April 15,  1999.  At that time,  the lock rate was  modified to
5.016% and the credit  threshold  reduced from $2.0 million to $0.5 million.  If
the market rate on ten-year  Treasury  Notes falls below the locked rate and the
difference  between  $170.0  million and the  calculated  notional  amount is in
excess of the credit threshold, cash deposits are required. On March 1, 1999, we
terminated the $160.0 million treasury lock agreement due to the change in terms
and  timing  of the IBM  Plaza  purchase  as a result  of the  amended  purchase
agreement.  We had  approximately  $0.6 million on deposit that was forfeited at
the time of  termination.  During the period  January 1, 1999 through  March 24,
1999,  we received net cash  settlements  of  approximately  $9.2 million  ($1.0
million related to the $170.0 million agreement, and $8.2 million related to the
$160.0 million agreement) related to both treasury lock agreements. If the yield
on U.S. ten-year Treasury Notes at settlement is less than the locked yield, the
difference  between $170.0 million and the  calculated  notional  amount will be
amortized  over the terms of the future debt  instruments  as an  adjustment  to
interest  expense.  We  intend  to  consummate  debt  transactions  equal to the
notional value of the remaining agreement.

     During the third quarter of 1998, we entered into  contracts to acquire two
land parcels and an option to acquire a land parcel,  all located in the Chicago
metropolitan  area, for a total purchase price of  approximately  $62.0 million.
The purchase price is subject to an additional  $2.2 million based upon the date
the  purchase is  completed.  We were  required to make cash escrow  deposits of
approximately $25.2 million (including a $25.0 million non-refundable  deposit).
As of  December  31,  1998,  we had made cash escrow  deposits of $15.2  million
related to these  contracts and the remaining  $10.0 million was made in January
1999. We made an additional  non-refundable deposit of $0.6 million on March 10,
1999 related to the additional purchase price adjustment.  We expect to complete
the  acquisitions  by the  end of the  second  quarter  of  1999.  However,  the
acquisitions are subject to our completion of due diligence and the satisfaction
of other customary closing conditions. There can be no assurance that any or all
of the acquisitions will be completed.

     On September  14, 1998,  we  established  a program to repurchase up to the
lesser of (i) 1,550,000 of our common shares or (ii) $7.5 million for our common
shares in open market and privately negotiated  transactions,  with share prices
not to  exceed  $20.00  per  common  share.  As of  December  31,  1998,  we had
repurchased   474,200   common  shares  for  an  aggregate   purchase  price  of
approximately  $7.3 million.  No additional  shares have been repurchased  since
December 31, 1998.

     As part of an annual  incentive  award  program,  on December 17, 1998, our
Board of Trustees  granted to nineteen  of our  officers  (two of whom are Board
members) and one Board  member,  25,694 common  shares.  The common share grants
vest 50% on January 15, 1999 and 50% on January 15, 2000.

     On January 8, 1999,  we filed our initial shelf  registration  statement on
Form S-3 with the  Securities  and Exchange  Commission to register up to $500.0
million of our equity and debt securities for future sale.

     During the period from January 1, 1999 through  March 25, 1999, we acquired
the following office and industrial properties:

     On February 8, 1999, we signed a contract with a buyer pursuant to which we
will construct an approximately  1,018 space parking garage,  with approximately
4,000 square feet of retail space, on  approximately  22,700 square feet of land
that we have under option to purchase in the Chicago central business  district,
and  sell  the  competed  parking  garage  to the  buyer.  The  sales  price  is
approximately $34.6 million, plus the value of any of the retail space leased by
us at the time of sale, currently estimated to be approximately $4.0 million. In
addition,  we are  entitled to an  additional  $1.0  million  from the buyer if,
within  15  years  after  our  sale  of the  parking  garage  to the  buyer,  we
substantially  complete an office  building  containing at least 800,000  square
feet of  office  space,  which is  occupied  by at least one  tenant  who is not
affiliated  with us. We have  acquired this land with the intent to construct an
office  building  which we will own for  lease.  The land  parcel for the office
building  could  not be  obtained  without  obtaining  the land for the  parking
parking  garage and in order to  construct an office  building,  parking must be
provided pursuant to zoning requirements.

SEGMENT REPORTING DATA

     See Note 15 to our  consolidated  financial  statements for a discussion on
our  operating  segment  data for the year ended  December  31, 1998 and for the
period from November 17, 1997 through December 31, 1997.

COMPETITION

     We compete with other owners and developers;  some of whom may have greater
resources and more experience than we.  Additionally,  the number of competitive
properties in any  particular  market or submarket in which our  properties  are
located could have a material  adverse effect on both our ability to lease space
at our properties or any newly-acquired property and on the rents charged at our
properties.  We believe that our existing Credit  Facilities and our access as a
public  company  to the  capital  markets to raise  funds  during  periods  when
conventional sources of financing may be unavailable or prohibitively  expensive
provide us with substantial competitive advantages. Further, we believe that our
capital structure and ability to acquire properties in exchange for common units
in our operating  partnership  and, thereby defer a seller's  potential  taxable
gain,  enhance our ability to consummate  transactions  quickly and to structure
more  competitive  acquisitions  than other real estate  companies in the market
which lack our access to capital  and  ability to acquire  property  with common
units.  See  "Business and Growth  Strategies-Acquisition  Strategy." We believe
that the  number of real  estate  developers  has  decreased  as a result of the
recessionary  market conditions and tight credit markets during the early 1990's
as well as the reluctance on the part of more conventional  financing sources to
fund development and acquisition  projects.  In addition, we believe that we are
one of a limited  number of  publicly-traded  real  estate  companies  primarily
focusing on the office and industrial market in the Chicago metropolitan area.

SERVICES COMPANY

     The  Services  Company was formed in March 1997 under the laws of the state
of Maryland.  The operating  partnership owns 100.0% of the nonvoting  preferred
stock of the Services Company, representing 95.0% of its economic value and also
has a $4.8 million  promissory  note issued from Services  Company in connection
with its formation.  We have also provided a $5.0 million  line-of-credit to the
Services  Company.  The ownership  structure  permits us to share in the Service
Company's  income and also maintain our status as a REIT for federal  income tax
purposes. We receive substantially all of the economic benefit of the businesses
carried  on by the  Services  Company  because  we have  the  right  to  receive
dividends through the operating partnership's  investment in the preferred stock
and interest payments on the note held by the operating partnership. However, we
do not elect the Services Company's officers or directors and, consequently,  do
not have the  ability to  control  the  operations  of the  Services  Company or
require the declaration of dividends.

     The Services  Company  provides  certain  corporate  advisory,  management,
leasing,  tenant  improvement  construction,  painting,  contracting  and tenant
representation  services to buildings  owned by others.  The Services  Company's
leasing  division  provides  leasing  services to certain of our  properties and
other property  owners for fees. The Services  Company's  construction  division
provides   construction   and  construction   management   services  for  tenant
improvements,  renovations  and  other  construction  to the  properties  owned,
acquired or managed by us. The Services Company also acquires, markets and sells
land.

GOVERNMENT REGULATION

     ENVIRONMENTAL  MATTERS.  All of our  properties  were subject to Phase I or
similar  environmental  assessments  by independent  environmental  consultants.
Phase I  assessments  are  intended to discover  information  regarding,  and to
evaluate the  environmental  condition of, the surveyed property and surrounding
properties. Phase I assessments generally include an historical review, a public
records  review,   an   investigation  of  the  surveyed  site  and  surrounding
properties,  and the preparation  and issuance of a written  report,  but do not
include soil sampling or subsurface investigations.

     We are  aware  of  environmental  contamination  at  certain  of our  older
industrial  properties  contributed by PGI. These  properties are in remediation
programs  sponsored by the appropriate  state  environmental  agencies.  PGI has
contractually  agreed to retain  liability,  and indemnify us, for environmental
remediation  with regard to these  industrial  properties,  which  environmental
consultants  have  estimated  will cost, in the  aggregate,  up to $3.2 million.
Based on such estimates,  certain properties PGI contributed recorded provisions
for environmental remediation costs totaling $3.2 million in 1997 prior to their
contribution. During 1997, PGI initiated lawsuits against a former owner (who is
also a former tenant) of one of the properties and an  environmental  consultant
to cover the cost of the  remedial  action  plans.  On February  20,  1998,  PGI
reached  an  agreement  with  the  former  owner  and  received  a $1.8  million
settlement   payment,   in  addition  to  $0.5  million  previously  paid  as  a
reimbursement  for  costs.  In 1998,  PGI sued a  current  tenant  of one of the
properties to recover the cost of certain remedial action plans.

     We are also aware of  contamination  at 455  Academy  Drive in  Northbrook,
Illinois. The current tenant of the property,  National Service Industries,  has
provided us with an indemnity for all of the costs of environmental  remediation
regarding the property they caused either knowingly or unknowingly. In addition,
we are aware of contamination at 1301 E. Tower Road in Schaumburg, Illinois. The
property has been submitted into a remediation program sponsored by the Illinois
Environmental  Protection  Agency and we are in the process of  quantifying  the
cost of necessary  remedial actions.  In connection with 1301 E. Tower Road, the
previous owner and other third parties have placed approximately $0.8 million in
escrow to fund the clean-up of the property.  We currently  anticipate that this
escrow  will be  sufficient  to fund  the  necessary  remedial  action  for this
property,  although  the  previous  owner and other  third  parties  will not be
responsible for any costs in excess of the amount placed in escrow.

     We believe  that our other  properties  are in  compliance  in all material
respects  with all federal,  state and local laws,  ordinances  and  regulations
regarding  hazardous  or toxic  substances.  We have not  been  notified  by any
governmental   authority,   and  are  not  otherwise   aware,  of  any  material
noncompliance,  liability or claim relating to hazardous or toxic  substances in
connection  with  any  of  our  other  properties.  None  of  our  environmental
assessments of the properties  have revealed any  environmental  liability that,
after giving effect to the contractual  indemnities and escrows described above,


                                      -10-
<PAGE>
we believe would have a material  adverse  effect on our financial  condition or
results of  operations  taken as a whole,  nor are we aware of any such material
environmental liability. Nonetheless, it is possible that our assessments do not
reveal all  environmental  liabilities or that there are material  environmental
liabilities  of which we are unaware.  Moreover,  there can be no assurance that
(i)  future  laws,  ordinances  or  regulations  will not  impose  any  material
environmental  liability  or (ii) the  current  environmental  condition  of our
properties  will  not be  affected  by  tenants,  by the  condition  of  land or
operations  in  the  vicinity  of  our  properties  (such  as  the  presence  of
underground  storage  tanks) or by third parties  unrelated to us. If compliance
with the  various  laws and  regulations,  now  existing or  hereafter  adopted,
exceeds our budgets for such items,  our ability to make expected  distributions
to shareholders could be adversely affected.

     COSTS OF COMPLIANCE  WITH AMERICANS WITH  DISABILITIES  ACT. Under the ADA,
all public accommodations and commercial facilities are required to meet certain
federal  requirements  related  to access  and use by  disabled  persons.  These
requirements  became  effective in 1992.  Compliance  with the ADA  requirements
could require removal of access barriers,  and noncompliance could result in the
imposition of fines by the federal  government or an award of damages to private
litigants.  We believe that our properties are  substantially in compliance with
these  requirements;  however,  we may incur additional costs to comply with the
ADA. Although we believe that such costs will not have a material adverse effect
on our  financial  position,  if required  changes  involve a greater  amount of
expenditures  than  we  currently  anticipate,  our  ability  to  make  expected
distributions could be adversely affected.

     OTHER  REGULATIONS.  Our  properties  are also subject to various  federal,
state and local regulatory  requirements,  such as state and local fire and life
safety  requirements.  Failure to comply with these requirements could result in
the  imposition  of fines by  governmental  authorities  or awards of damages to
private  litigants.  We believe that our  properties  are  currently in material
compliance  with all such  regulatory  requirements.  However,  there  can be no
assurance that these  requirements  will not be changed or that new requirements
will not be imposed  which would  require us to make  significant  unanticipated
expenditures  and could have an adverse effect on our Funds from  Operations and
expected distributions.

INSURANCE

     We  believe  that our  properties  are  covered by  adequate  comprehensive
liability, rental loss, and all-risk insurance, provided by reputable companies,
with  commercially  reasonable  deductibles,  limits and  policy  specifications
customarily carried for similar properties. There are, however, certain types of
losses which may be either  uninsurable or not economically  insurable,  such as
losses due to floods,  riots or acts of war.  Should an uninsured loss occur, we
could lose both our  invested  capital in, and  anticipated  profits  from,  the
property.

EMPLOYEES

     As of December 31, 1998, we had approximately 200 full-time  employees.  We
believe that our relations with our employees are satisfactory.

ITEM 2.  PROPERTIES

GENERAL

     As of December 31, 1998, we owned 24 office properties (including 1701 Golf
Road, on which we own a second mortgage note, but for which we have consolidated
the property's operations),  46 industrial properties, one retail center and one
parking   facility.   Our  properties  are  located  primarily  in  the  Chicago
metropolitan area. In addition,  we own a mortgage on an office property located
at 180 N. LaSalle Street, in the Chicago central business district.  In terms of
net rentable square feet, approximately 90.2% of our office properties and 89.7%
of our  industrial  properties are located in the Chicago  metropolitan  area in
prime business locations within established business communities. The properties
located in the Chicago  metropolitan area accounted for  approximately  90.8% of
our rental revenue and 98.0% of our tenant  reimbursements  revenue for the year
ended December 31, 1998.

     Our management team has developed or redeveloped,  leased and managed 40 of
our 46 industrial  properties  (85.0% in terms of industrial net rentable square
feet) and 11 of our 24 office  properties (47.3% in terms of office net rentable
square  feet).  In the course of such  development  and  redevelopment,  we have
acquired  experience  across a broad  range  of  development  and  redevelopment


                                      -11-
<PAGE>
projects. For example, our management team has developed both office properties,
such as the 77 West Wacker Drive building in Chicago,  Illinois,  and industrial
properties,  such as 1001 Technology Way and 801 Technology Way in Libertyville,
Illinois. Our management team also has redeveloped both office properties,  such
as 201 4th Avenue in Nashville, Tennessee and industrial properties, such as the
Chicago  Enterprise   Center,   East  Chicago  Enterprise  Center,  and  Hammond
Enterprise  Center in the Chicago  metropolitan  area. We believe our properties
are well maintained  and, based on recent  engineering  reports,  do not require
significant capital improvements.

     We own approximately 225.0 acres of land that we may develop.  This acreage
includes a  development  site which  contains  approximately  67,000 square feet
located in the Chicago central business  district and is held by a joint venture
with a third party. We also have rights to acquire  approximately 325.8 acres of
developable  land,  including rights to acquire two sites located in the Chicago
central  business  district  containing  approximately  119,000  square feet. We
believe  that this land could be  developed  to have  approximately  4.7 million
square  feet of  additional  office  space and over 7.6  million  square feet of
additional  industrial  space.  Included  in the 325.8 acres are 94 acres and an
industrial  property  currently  under  development  that we are to acquire from
affiliates  of a member of our Board of Trustees for a total  purchase  price of
$20.9 million.

     Our office  properties are leased to tenants either (i) on a net basis with
tenants  obligated  to pay  their  proportionate  share  of real  estate  taxes,
insurance,  utility and  operating  expenses or (ii) on a gross basis,  with the
landlord responsible for the payment of these expenses up to the amount incurred
during the tenants first year of occupancy ("Base Year") or a negotiated  amount
approximating the tenants pro rata share of these expenses ("Expense Stop"). The
tenants pay their pro rata share of increases in expenses above the Base Year or
Expense Stop.  Most of the leases for our  industrial  properties are written on
either a (i) net basis,  with tenants paying their  proportionate  share of real
estate taxes, insurance, utility and other operating expenses as additional rent
or (ii) triple net lease  basis with the  tenants  paying all of the real estate
taxes, insurance, utility and other operating expenses for the property.

PROPERTIES

     The following table sets forth certain information  relating to each of our
properties  as of December 31, 1998,  unless  indicated  otherwise.  Through the
operating  partnership and other subsidiaries,  we own a 100% interest in all of
the office and the industrial properties,  except for 1701 Golf Road (we own the
second  mortgage note on this  property)  and 180 N. LaSalle  Street (we own the
first mortgage note on this property).

ITEM 3.  LEGAL PROCEEDINGS

     Neither we nor any of our properties are presently  subject to any material
litigation  nor, to the our  knowledge,  is any material  litigation  threatened
against us, other than  routine  litigation  arising in the  ordinary  course of
business, some of which is expected to be covered by liability insurance and all
of which  collectively is not expected to have a material  adverse effect on our
consolidated  financial  statements.  Although  subsequently settled in February
1999, we were subject to the litigation discussed below as of December 31, 1998.

     On July 22, 1998, we entered into a purchase  agreement,  with an affiliate
of an investor in the operating  partnership,  to acquire two office  buildings,
IBM Plaza (a  1,354,354  square  foot  office  building  located in the  Chicago
central  business  district)  and  National  City Center (a 766,965  square foot
office building located in Cleveland,  Ohio) for an aggregate  purchase price of
approximately  $357.0 million. On September 15, 1998, we terminated the purchase
agreement in accordance  with the terms of the agreement due to the failure of a
material condition precedent to the closing of these acquisitions.  On September
21,  1998,  the sellers  notified  us in writing  that they  believed  they were
entitled to the $20.0 million  earnest money provided for by the agreement,  and
instructed  the earnest  money  escrow  agent to draw the full amount  under two
earnest money  letters-of-credit we provided under one of the Credit Facilities.
The  sellers  also filed a complaint  against us with the  Supreme  Court of New
York,  New York County  alleging that we breached the  contract.  On October 30,
1998,  we  filed our answer to the complaint and denied all material allegations


                                      -14-
<PAGE>
of the complaint. We also filed a counterclaim against the sellers alleging that
the sellers  breached the contract and sought the return of the above  mentioned
earnest money and other damages.

     On February 5, 1999, we entered into an amended  option  agreement with the
sellers  of IBM Plaza and an  amended  purchase  agreement  with the  sellers of
National City Center, which have the following terms:

     -    both the  original  lawsuit  filed by the sellers and our counterclaim
          were dismissed;

     -    we purchased  National  City Center on February 5, 1999 for a contract
          price of $100.0 million; and

     -    the $20.0 million  earnest money escrow  described  above was released
          and  credited  to the  purchase  of  National  City Center and an $8.0
          million  nonrefundable  payment for the option to purchase  IBM Plaza.
          The  option  allows  us to  purchase  IBM  Plaza  for  $238.0  million
          (including the $8.0 million  deposit) and expires October 31, 1999. If
          the  option  is  exercised,  the  purchase  of the  property  must  be
          completed no later than December 20, 1999.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITYHOLDERS

     No matters  were  submitted  to vote of  securityholders  during the fourth
quarter of 1998.

(3)  This  distribution  was  for  a  partial  quarter.  It is  equivalent  to a
     quarterly distribution of $0.3375 per common share and common unit.

     We currently make quarterly  distributions  to holders of our common shares
and operating  partnership common units.  Distributions on the common shares and
common  units  are  not  permitted   unless  all  current  and  any  accumulated
distributions on our Series A - cumulative  convertible  preferred  shares,  our
Series B -  Cumulative  Redeemable  Preferred  Shares and the related  preferred
units in the  operating  partnership  have  been  paid in full or set  aside for
payment.  Future  distributions  by us will be at the  direction of our Board of
Trustees.  These  distributions  will  depend on the actual cash  available  for
distribution,   our  financial  condition,  capital  requirements,   the  annual
distribution requirements under the REIT provisions of the Internal Revenue Code
and such other factors as our Board of Trustees deems relevant.

     Concurrently  with the  completion  of our  initial  public  offering,  the
operating  partnership  issued  9,994,310  common units to PGI,  the  Primestone
Investment  Partners  L. P. (a joint  venture of PGI and a third  party),  other
contributors  and  certain  members  of  management  in  exchange  for  property
contributions  and cash.  In  addition,  the  operating  partnership  has issued
323,590 common units through December 31, 1998 as partial  consideration for its
acquisition  of the first  mortgage  note of 180 N. LaSalle  Street.  Holders of
9,390,800  of the above  mentioned  common  units may redeem  part or all of the
common units for common shares on a one-for-one  basis,  or at our option,  cash
equal to the fair market value of a common share at the time of exchange.

     Also  concurrently  with the completion of our initial public offering,  we
issued  2,000,000 of our Series A - Cumulative  Convertible  Preferred Shares of
Beneficial  Interest,  $0.01 par value per share,  in a private  placement to an
institutional investor for an aggregate purchase price of $40.0 million. Holders
of our Series A - Cumulative  Convertible  Preferred  Shares can convert them to
our common shares.

     On March  25,1998,  we issued  2,579,994 of our common  shares in a private
placement.  In addition,  during 1998, we granted 50,694 of our common shares to
certain of our officers and board members. See "Business - Recent Developments."

     The  issuance of 2,579,994  of our common  shares,  the common share grants
described  above to certain of our  employees  and  trustees,  the common  units
described  above and our  Series A -  Cumulative  Convertible  Preferred  Shares
constituted   private  placements  of  securities  which  are  exempt  from  the
registration requirements of the Securities Act of 1933, as amended, pursuant to
Section 4(2) thereof.

     Note 8 to our consolidated financial statements for further information.

(2)  As defined by the National  Association  of Real Estate  Investment  Trusts
     ("NAREIT"),  Funds from  Operations  represents  net income  (loss)  before
     minority  interest of holders of Common Units  (computed in accordance with
     GAAP),  excluding  gains (or losses) from debt  restructuring  and sales of
     property, plus real estate related depreciation and amortization (excluding
     amortization  of  deferred  financing  costs)  and  after  adjustments  for
     unconsolidated  partnerships  and joint ventures.  Non-cash  adjustments to
     Funds from Operations  were as follows:  in all periods,  depreciation  and
     amortization,  for the period from  January 1, 1997  through  November  16,
     1997,  provision for  environmental  remediation  cost, for the years ended
     December 31, 1996, 1995,  1994,  gains on the sale of real estate,  for the
     years ended December 31, 1996 and 1995, write-off of deferred tenant costs,
     and for the year ended  December 31, 1995,  excess  proceeds from insurance
     claims.  Management  considers Funds from Operations an appropriate measure
     of  performance  of an  office  and/or  industrial  REIT  because  industry
     analysts  have  accepted it as such.  We compute  Funds from  Operations in

                                      -18-
<PAGE>

     accordance  with standards  established by the Board of Governors of NAREIT
     in its March 1995 White Paper  (with the  exception  that we report  rental
     revenues on a cash basis (based on contractual lease terms),  rather than a
     straight-line  GAAP  basis,  which we believe  results  in a more  accurate
     presentation of our actual operating activities), which may differ from the
     methodology for calculating  Funds from Operations used by other REITs and,
     accordingly, may not be comparable to such other REITs. Further, Funds from
     Operations   does  not  represent   amounts   available  for   management's
     discretionary use because of needed capital replacement or expansion,  debt
     repayment obligations,  or other commitments and uncertainties.  Funds from
     Operations  should not be considered as an alternative  for net income as a
     measure of  profitability  nor is it comparable  to cash flows  provided by
     operating activities determined in accordance with GAAP.

(3)  The ratios of earnings  to  combined  fixed  charges  and  preferred  share
     distributions  were computed by dividing earnings by combined fixed charges
     and preferred share  distributions.  For this purpose,  earnings consist of
     income (loss)  before  minority  interest,  plus  combined  fixed  charges.
     Combined fixed charges  consist of interest  expense,  amortization of debt
     issuance  costs,  and  preferred  share  distributions.  The  Predecessor's
     historical   earnings   were   insufficient   to  cover  fixed  charges  by
     approximately $29.1 million, $31.4 million, $29.6 million and $22.1 million
     for the period from January 1, 1997  through  November 16, 1997 and for the
     years ended December 31, 1996, 1995, and 1994, respectively.

     The following is our consolidated quarterly summary of operations.

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

OVERVIEW

     The following  discussion should be read in conjunction with our historical
consolidated  financial  statements  and the  predecessor's  combined  financial
statements and related notes thereto included elsewhere in this Form 10-K.

     We are a  fully-integrated  real estate investment  company organized under
Maryland law, providing property management,  leasing,  marketing,  acquisition,
development, redevelopment, construction, finance and other related services. As
of December 31, 1998, we owned 24 office  properties (eight were acquired during
1998  and the  remaining  were  owned  at  December  31,  1997),  46  industrial
properties  (all were owned at December 31, 1997),  one retail  center,  and one
parking   facility.   Our  properties  are  located  primarily  in  the  Chicago
metropolitan area. In addition,  we own a mortgage on an office property located
at 180 N. LaSalle Street, Chicago, Illinois.

     As  of  December  31,  1998,   in  terms  of  net  rentable   square  feet,
approximately  90.2%  of our  office  properties  and  89.7%  of our  industrial
properties  were  located in the  Chicago  metropolitan  area in prime  business
locations within established business communities. The properties located in the
Chicago  metropolitan area account for approximately 90.8% of our rental revenue
and 98.0% of our tenant  reimbursements  revenue for the year ended December 31,
1998. Our remaining office  properties are located in the Nashville,  Tennessee;
Knoxville, Tennessee; and Milwaukee, Wisconsin metropolitan areas. Our remaining
industrial properties are located in the Columbus, Ohio metropolitan area.

     Our income is derived  primarily  from  rental  revenue  (including  tenant
reimbursements)  from our  properties  supplemented  by  interest  income on the
mortgage note owned.  We expect that revenue  growth over the next several years
will come from a combination of additional  acquisitions  and revenue  generated
through increased rental and occupancy rates in the current portfolio.

CAUTIONARY STATEMENTS

     The  following  discussion  in  "Management's  Discussion  and  Analysis of
Financial Condition and Results of Operations"  contain certain  forward-looking
statements within the meaning of the Private Securities Litigation Reform Act of
1995 which reflect  management's current views with respect to future events and
financial  performance.  Such forward-looking  statements are subject to certain
risks and  uncertainties;  including,  but not limited to, the effects of future
events on our financial  performance;  the risk that we may be unable to finance
our  planned  acquisition  and  development  activities;  risks  related  to the
industrial and office  industry in which our properties  compete,  including the
potential  adverse  impact  of  external  factors  such as  inflation,  consumer
confidence,  unemployment  rates and  consumer  tastes  and  preferences;  risks
associated  with our  development  activities,  such as the  potential  for cost
overruns,  delays  and lack of  predictability  with  respect  to the  financial
returns  associated  with these  development  activities;  the risk of potential
increase in market interest rates from current rates;  and risks associated with
real estate  ownership,  such as the potential  adverse impact of changes in the
local economic climate on the revenues and the value of our properties.

RESULTS OF OPERATIONS

     The  following  analysis  provides a comparison of our  operations  for the
years ended  December 31, 1998 and 1997. The period from January 1, 1997 through
November 16, 1997  represents the activity of the  Predecessor's  properties and
the period from  November 17, 1997  through  December  31, 1998  represents  our
activity.

     YEAR ENDED DECEMBER 31, 1998 COMPARED TO THE YEAR ENDED DECEMBER 31, 1997

     In analyzing  the operating  results for the year ended  December 31, 1998,
the changes in rental and reimbursable  revenue,  property  operating  expenses,
real  estate  taxes  and  depreciation  and  amortization   from  1997  are  due
principally to the addition of operating results from properties contributed and
acquired as part of our initial public  offering as well as properties  acquired
after our initial public offering through December 31, 1998.

     The Predecessor's properties currently owned by us consisted of five office
properties, 17 industrial properties, and a parking facility. At the time of our
initial  public  offering,  nine  additional  office  properties,  29 additional
industrial properties and one retail center were contributed or acquired.  After


                                      -20-
<PAGE>
the date of our initial  public  offering  and through  December  31,  1998,  we
acquired ten additional  office properties and a first mortgage note encumbering
an office property as described in the footnotes to our  consolidated  financial
statements contained elsewhere in this Form 10-K.

     For  the  year  ended   December  31,  1998,   rental  revenue  and  tenant
reimbursements income increased $85.0 million, or 170.7%, to $134.8 million, and
other revenue  increased  $5.5  million,  or 372.4%,  to $7.0 million,  property
operating  expenses  and real estate tax expense  increased  $33.5  million,  or
158.2%,  to $54.7 million,  and depreciation and amortization  expense increased
$11.7 million, or 85.5%, to $25.4 million as compared to the year ended December
31, 1997.  The primary reason for the increases in the above revenue and expense
categories  was the  contribution  and  acquisition of new office and industrial
properties we have made since our initial public offering. The additional office
and industrial  properties resulted in increased total rental revenue and tenant
reimbursements income of $88.6 million, other revenue of $5.0 million,  property
operating expenses and real estate tax expense of $35.4 million and depreciation
and amortization  expense of $11.9 million for the year ended December 31, 1998.
Included in the rental  revenue  increase  for 1998 is $4.1  million  related to
lease  terminations.  Rental  revenue and tenant  reimbursement  revenue for the
Predecessor's  properties increased $0.6 million for the year ended December 31,
1998 compared to the same period in 1997.  Depreciation and amortization expense
for the  Predecessor's  properties  increased  $0.7  million  for the year ended
December 31, 1998 compared to the same period in 1997.

     Mortgage note interest income increased by $5.6 million to $5.9 million due
to the acquisition of the first mortgage note  encumbering the property known as
180 North LaSalle Street in December 1997.

     Interest  expense had a net increase of $4.6  million,  or 17.5%,  to $30.9
million during the year ended December 31, 1998. The increase was due to a $36.2
million  increase due to mortgages  obtained on certain of the properties  which
were contributed or acquired after our initial public  offering,  as well as our
Credit  Facilities  borrowings used to fund property  acquisitions,  offset by a
$31.6  million  decrease as a result of the repayment of debt with proceeds from
our initial public offering or debt forgiveness in 1997.

     General and  administrative  expense increased $3.0 million during the year
ended December 31, 1998,  reflecting  costs related to our new public status and
increased size.

     The $1.2 million  decrease in financing fees and the $1.3 million  decrease
in property and asset  management  fees are due to these fees being  incurred by
the Predecessor under their previous ownership and are costs we no longer incur.

     In 1997, the Predecessor recorded a provision for environmental remediation
costs of $3.2 million,  which  represents the estimated costs to be incurred for
the clean-up of environmental  contamination of certain  industrial  properties.
PGI has contractually agreed to indemnify us from any environmental  liabilities
we may incur. No additional provision was deemed necessary in 1998.

     Income  allocated  to minority  interests  increased  $9.4  million to $9.4
million for the year ended December 31, 1998 compared to the same period in 1997
due to an increase in income  before  minority  interest  of $58.5  million,  or
212.0%,  to $30.9  million due to the changes in revenue and expenses  described
above and a change in the  ownership  structure.  The increase in income  before
minority  interests is due to additional  properties either being contributed or
acquired and the effects they had on revenue and expenses  described  above. The
change in ownership structure is due to certain ownership  percentages  changing
do to our initial public offering.

     Extraordinary  gain on  extinguishment of debt decreased $67.2 million to a
$1.3 million  extraordinary loss in 1998, due to the gain in 1997 related to the
forgiveness  of debt principal net of the write-off of various  deferred  costs,
while the loss in 1998 represents only the write-off deferred costs for mortgage
indebtness  that was repaid or refinanced and a reduction in the maximum balance
that can be drawn on one of our Credit Facilities.

     Net income decreased $18.2 million, or 47.3%, to $20.2 million for the year
ended  December 31, 1998  compared to the same period in 1997 due to the changes
in revenue,  expenses,  minority  interest,  and  extraordinary  items described
above.

     The following analysis provides a comparison of the property operations for
the years  ended  December  31, 1997 and 1996.  The period from  January 1, 1997
through  November 16, 1997 and the year ended  December 31, 1996  represents the
activity of the  Predecessors  properties  and the period from November 17, 1997
through December 31, 1997 represents our activity.

<PAGE>
     YEAR ENDED DECEMBER 31, 1997 COMPARED TO THE YEAR ENDED DECEMBER 31, 1996.

     Total revenue  increased  $3.6  million,  or 7.5%, to $51.8 million for the
year ended  December  31,  1997  compared  to $48.2  million  for the year ended
December 31, 1996 primarily due to the addition of the  properties  acquired and
contributed  at our initial  public  offering.  Rental  revenue  increased  $4.7
million, or 15.4%, to $35.2 million in 1997 from $30.5 million in 1996. In 1997,
rental revenue from our office properties  increased $3.2 million,  or 13.0%, to
$27.9  million  from $24.7  million in 1996.  In 1997,  rental  revenue from our
industrial  properties  increased $1.5 million,  or 25.9%,  to $7.3 million from
$5.8 million in 1996. Tenant  reimbursements  revenue increased $0.3 million, or
2.1%, to $14.5 million in 1997 from $14.2 million in 1996. Tenant reimbursements
revenue from our office properties remained consistent at $12.1 million for both
1997 and 1996.  During 1996 a significant  tenant of the 77 West Wacker building
paid no tenant reimbursements until a final restructuring  agreement was reached
in late 1996.  During  1997,  the above  mentioned  tenant paid $0.6  million of
tenant  reimbursements.  Tenant  reimbursements  from our industrial  properties
increased $0.3 million,  or 14.3%,  to $2.4 million in 1997 from $2.1 million in
1996.  Other  nonrecurring  items recorded in 1996 resulted in a net decrease of
$1.4 million,  or 41.2%,  in all other revenue to $2.0 million in 1997 from $3.4
million in 1996.  Included in our historical  financials,  related to the period
from November 17, 1997 to December 31, 1997 are rental revenues of $3.5 million,
tenant revenue  reimbursements of $0.8 million and $0.4 million of other revenue
related to the  non-Predecessor  properties  contributed or acquired during that
period

     Total expenses  decreased  $0.2 million,  or 0.3%, to $79.4 million for the
year ended  December  31,  1997  compared  to $79.6  million  for the year ended
December 31, 1996. Property operating expenses increased $1.0 million, or 11.2%,
to $10.8 million in 1997 from $9.8 million in 1996. In 1997,  property operating
expenses from our office  properties  increased $1.6 million,  or 19.5%, to $9.8
million for the year ended  December  31, 1997  compared to $8.2 million for the
year  ended  December  31,  1996.  The  property  operating  expenses  from  our
industrial  properties decreased $0.6 million, or 37.5%, to $1.0 million for the
year  ended  December  31,  1997  compared  to $1.6  million  for the year ended
December 31, 1996. In 1997, real estate tax expenses increased $1.0 million,  or
10.6%,  to $10.4  million  from $9.4  million  in 1996  primarily  due to higher
property  assessments in 1997. In 1997,  total interest  expense  decreased $1.1
million,  or 3.0%, to $36.1 million from $37.2 million in 1996  primarily due to
the  paydown of a  mortgage  note  collateralized  by the 77 West  Wacker  Drive
building.  In 1997, general and administrative  expenses decreased $2.2 million,
or  44.5%,  to $2.7  million  from $4.9  million  in 1996  primarily  due to the
nonrecurring  expenses  recorded  in the last six months of 1996.  In 1997,  the
Predecessor  recorded a provision for  environmental  remediation  costs of $3.2
million,  which represents the probable costs to be incurred for the clean-up of
environmental   contamination  at  certain   industrial   properties.   PGI  has
contractually  agreed to indemnify us from any environmental  liabilities we may
incur.  Other expenses  decreased $2.1 million on a net basis in 1997 from $18.3
million in 1996 compared to $16.2 million in 1997 primarily due to the write-off
of deferred tenant costs in 1996. Included in our historical  financials related
to the period  from  November  17,  1997 to  December  31,  1997,  are  property
operating  expenses of $0.6  million,  real estate tax expense of $0.6  million,
interest expense of $1.3 million and general and administrative  expense of $0.7
million related to the non Predecessor properties contributed of acquired during
the period.

     In 1997, net loss allocated to minority  interests  decreased $0.8 million,
or 88.9%,  to $0.1  million  from $0.9  million  in 1996,  primarily  due to the
changes  described above and an overall change in minority  interests  ownership
due to our initial public offering.

     In 1997,  net income of $38.4  million was  reported  compared to a loss of
$30.5  million in 1996,  primarily  due to the changes  described  above and the
extraordinary  gain on early  extinguishment  of debt of $66.0  million,  net of
minority interests, recorded in 1997.

LIQUIDITY AND CAPITAL RESOURCES

     CREDIT FACILITIES. Our Credit Facilities,  with a maximum loan availability
totaling $90.0 million,  have been provided by various  financial  institutions,
and are  collateralized  by first mortgages on certain  properties  owned by the
operating  partnership.  Subject  to our  compliance  with the  applicable  loan
covenants,  the Credit  Facilities may be used to provide funds for acquisitions
and development activities and to provide the replacement  letters-of-credit for
the  $26.9  million  of  tax-exempt  bonds.  No  amounts  were  drawn on  Credit



                                      -22-
<PAGE>
Facilities  at December  31, 1998  (except for the  letters-of-credit  impact on
current  availability).  See Note 4 to our consolidated financial statements for
further  information.  In January and February  1999, we drew $30.0 million from
our Credit Facilities to acquire two office buildings.

     MORTGAGE  NOTES.  We have  financed  a  portion  of our  acquisitions  with
proceeds from mortgage notes payable from various financial  institutions,  with
fixed and variable  interest  rates and maturities of 1999 through 2013. We feel
that our  properties  have  excess  value that may be  utilized  for  additional
mortgage  borrowing  or debt  securitizations.  See  Note 4 to our  consolidated
financial statements for further information.

     FUTURE  OFFERINGS.   On  January  8,  1999,  we  filed  our  initial  shelf
registration  statement on Form S-3 with the Securities and Exchange  Commission
to register up to $500.0  million of our equity and debt  securities  for future
sale.

     We intend to fund future acquisitions and development with a combination of
advances  from our Credit  Facilities,  additional  mortgage  notes  payable and
future equity and debt offerings.

     ANALYSIS OF LIQUIDITY AND CAPITAL RESOURCES.

     We expect to meet our short-term  liquidity  requirements  through net cash
provided by operations.  Our properties require periodic  investments of capital
for tenant-related  capital  expenditures and for general capital  improvements.
During 1998, our tenant improvements and leasing commissions averaged $18.04 per
square  foot of newly  leased  office  space,  $3.85 per square  foot of renewal
leased office space, and $4.53 per square foot of newly leased industrial space.
Our  estimated  annual  cost  of  recurring  tenant   improvements  and  leasing
commissions is approximately  $8.6 million based upon average annual square feet
for leases expiring during the years ending December 31, 1999 and 2000. Our cost
of general capital  improvements to our properties  average  approximately  $3.0
million annually based upon an estimate of $0.26 per square foot.

     We expect to meet our long-term  liquidity  requirements for the funding of
property  development,  property  acquisitions and other  non-recurring  capital
improvements  through  a  combination  of net cash  from  operations,  long-term
secured and unsecured  indebtedness  (including the Credit  Facilities)  and the
issuance of additional equity securities. The terms of the Credit Facilities and
our preferred  shares impose  restrictions on our ability to incur  indebtedness
and issue additional preferred shares.

HISTORICAL CASH FLOWS

     Historically, we have generated positive cash flows from operations to fund
distributions  to our  shareholders  and have  funded  our  expansion  primarily
through  equity  offerings  and  mortgage  debt  financing.   Historically,  the
Predecessor's   principal   sources  of  funding  for   operations  and  capital
expenditures were from mortgage debt financing.

     We had  consolidated  net cash  provided by operating  activities  of $53.5
million  for the year  ended  December  31,  1998.  We and the  Predecessor  had
consolidated  and combined net cash  provided by  operating  activities  of $2.5
million for the year ended  December 31, 1997 and the  Predecessor  had combined
net cash  used in  operating  activities  of $2.5  million  for the  year  ended
December 31, 1996. The $51.0 million  increase in net cash provided by operating
activities for the year ended December 31, 1998 from the year ended December 31,
1997 was primarily due to a $67.2 million  decrease in  extraordinary  items,  a
$9.4 million increase in income allocated to minority interests, a $11.7 million
increase in  depreciation  and  amortization,  a $4.6 million  increase in other
liabilities,  a $3.8  million  increase  in accrued  real estate  taxes,  a $2.5
million  increase in accrued  interest  payable,  and a $0.3 million decrease in
gain of sale of real estate, offset by a $18.2 million decrease in net income, a
$11.7  million  increase in other  assets,  a $9.8 million  decrease in interest
added to principal on mortgage note payable  affiliate,  a $3.1 million decrease
in accounts  payable and accrued  expenses,  a $2.5  million  increase in tenant
receivables, a $1.9 million decrease in deferred rent receivable, a $1.0 million
increase in interest income and developer fees added to mortgage note receivable
principal  and a $0.5 million  decrease in standby loan  fee-affiliate  added to
principal on mortgage note payable  affiliate.  The $4.9 million increase in net
cash provided by operating  activities for the year ended December 31, 1997 from
the year ended  December 31, 1996 was primarily due to a $68.9 million  increase
in net income,  a $1.3 million decrease in deferred tenant  receivables,  a $0.6
million  decrease in gain on sale of real  estate,  a $1.3  million  increase in
depreciation and amortization expense, a $0.9 million decrease in loss allocated


                                      -23-
<PAGE>
to minority interest, a $7.7 million increase in accrued real estate taxes and a
$9.3 million increase in accounts payable and accrued expenses, offset by a $0.2
million decrease in interest added to principal,  a $3.1 million decrease in the
write-off of deferred  tenant costs, a $66.0 million  increase in  extraordinary
gain, a $2.9 million increase in tenant receivables, a $10.1 million increase in
other  assets,  a $1.6 million  decrease in accrued  interest and a $1.1 million
decrease in other liabilities.

     We had consolidated net cash used in investing activities of $361.4 million
for the year ended December 31, 1998. We and the  Predecessor  had  consolidated
and combined net cash used in investing  activities of ($357.8  million) for the
year ended December 31, 1997 and the  Predecessor had combined net cash provided
by investing  activities  of $0.4 million for the year ended  December 31, 1996.
The $3.6 million increase in net cash used in investing  activities for the year
ended  December 31, 1998 from the year ended December 31, 1997 was primarily due
to a $46.2  million  decrease in advances on mortgage  note  receivable,  a $1.6
million decrease in expenditures  for real estate and equipment,  a $1.2 million
decrease in due from affiliates and a $0.4 million  decrease in cash contributed
to the Services  Company,  offset by a $50.7 million increase in restricted cash
escrows,  a $1.3  million  increase in deferred  leasing  costs,  a $0.6 million
increase in loans provided to the Service Company and a $0.3 million decrease in
proceeds from sale of real estate.  The $358.2 million increase in net cash used
in investing activities for the year ended December 31, 1997 from the year ended
December 31, 1996 was primarily due to a $1.8 million  decrease in proceeds from
the sale of real estate, a $298.8 million increase in real estate  expenditures,
a $51.2 million purchase of a mortgage note receivable,  a $0.8 million increase
in deferred costs, a $5.2 million  increase in amounts due from affiliates and a
$0.4 million cash contribution to the Services Company.

     We had  consolidated  net cash  provided by financing  activities of $342.4
million  for the year  ended  December  31,  1998.  We and the  Predecessor  had
consolidated  and combined net cash  provided by financing  activities of $361.7
million for the year ended December 31,1997 and the Predecessor had combined net
cash  provided  by  financing  activities  of $5.7  million  for the year  ended
December 31, 1996. The $19.3 million  decrease in net cash provided by financing
activities for the year ended December 31, 1998 from the year ended December 31,
1997 was primarily due to a $215.7 million net decrease in the net proceeds from
the sale of our preferred and common shares and operating  partnership  units, a
$7.3 million  increase in cash used to  repurchase  our common  shares,  a $43.3
million increase in the repayment of mortgage notes payable and net repayment of
credit  facilities,  a $35.2 million  increase in distributions to our preferred
and common shareholders and the operating  partnership's  minority interest unit
holders,  a $19.1 million increase in financings  costs, a $5.6 million decrease
in proceeds from mortgage note payable affiliates,  and a $44.3 million decrease
in contributions  from predecessor  partners offset by a $305.4 million increase
in proceeds from mortgage notes payable and net proceeds from credit facilities,
a $42.3  million  decrease in the  repayment  of  mortgage  notes  payable  from
affiliates,  a $0.7  million  decrease in due from  affiliates,  a $1.0  million
contribution  from minority interest - other and a $1.7 million decrease in debt
termination  fees. The $356.0 million increase in net cash provided by financing
activities for the year ended December 31, 1997 from the year ended December 31,
1996 was primarily due to $272.0 million in net proceeds from our initial public
offering,   private  placement,   $85.0  million  from  the  sale  of  operating
partnership  units,  a $242.4  million  increase in proceeds from mortgage notes
payable,  and  a  $44.3  million  increase  in  contributions  from  Predecessor
partners, offset by a $236.6 million increase in the repayment of mortgage notes
payable,  a $45.1 million  increase in the  repayment of mortgage  notes payable
affiliates,  the payment of $5.0  million of deferred  financing  costs and debt
termination fees and a $0.5 million decrease in due to affiliates.

FUNDS FROM OPERATIONS

     Industry analysts generally  consider Funds from Operations,  as defined by
NAREIT,  an alternative  measure of  performance  of an equity REIT.  Funds from
Operations  is  defined  by  NAREIT  to mean net  income  (loss)  determined  in
accordance with GAAP,  excluding gains (or losses) from debt  restructuring  and
sales of property,  plus depreciation and amortization  (other than amortization
of deferred  financing  costs and  depreciation  of non-real  estate assets) and
after adjustment for unconsolidated  partnerships and joint ventures. We believe
that in order to facilitate a clear understanding of our consolidated historical
operating results and the Predecessor's  combined historical  operating results,
Funds from Operations  should be examined in conjunction  with net income (loss)
as presented in audited  combined  financial  statements and selected  financial
data included  elsewhere in this Form 10-K. We compute Funds from  Operations in
accordance with standards established by the Board of Governors of NAREIT in its



                                      -24-
<PAGE>
March 1995 White Paper (with the exception  that we report rental  revenues on a
cash basis (based on contractual lease terms),  rather than a straight-line GAAP
basis,  which we believe  results in a more accurate  presentation of our actual
operating  activities),  which may differ from the  methodology  for calculating
Funds  from  Operations  used  by  other  REITs  and,  accordingly,  may  not be
comparable to such other REITs. As a result of our reporting  rental revenues on
a cash basis for Funds from  Operations,  contractual  rent increases will cause
reported Funds from Operations to increase.  Further, Funds from Operations does
not represent  amounts  available for management's  discretionary use because of
needed capital replacement or expansion,  debt repayment  obligations,  or other
commitments and uncertainties. Funds from Operations should not be considered as
an alternative to net income (loss),  as an indication of our  performance or to
cash flows as a measure of  liquidity  or the ability to pay  dividends  or make
distributions.

     The  following  is  our  consolidated   quarterly  summary  of  Funds  From
Operations.

YEAR 2000

     The year 2000 ("Y2K") issue refers generally to computer applications using
only the last two digits to refer to a year  rather than all four  digits.  As a
result,  these  applications  could  fail or create  erroneous  results  if they
recognize  "00" as the year 1900  rather  than the year 2000.  We have taken Y2K
initiatives in the following three general areas:

     INFORMATION TECHNOLOGY

     We have focused our efforts on the high-risk areas of the corporate  office
computer hardware,  operating systems and software  applications.  The principal
risks  relating to our  information  technology  are failure to  correctly  bill
tenants and pay  invoices.  Our  assessment  and  testing of existing  equipment
revealed that our hardware,  network operating  systems,  secondary  information
systems  and  desktop  software  applications  are Y2K  compliant.  However,  we
currently have four accounting and property  management systems that are not Y2K
compliant.  We initiated a  comprehensive  corporation  wide plan in mid-1998 to



                                      -25-
<PAGE>
completely  replace our financial and operational  systems by the fourth quarter
of 1999 in order to  facilitate  our future  growth  and to improve  operational
controls.  We  anticipate  the total cost of this effort will be $3.5 million to
$4.0 million and will have the  additional  benefit of making our  financial and
operational  systems Y2K  compliant.  Of the total  project  costs,  we estimate
approximately  $3.2 million to $3.7 million is  attributable to the purchase and
implementation  of new software and equipment  which will be capitalized and the
remainder  related to the  assessment,  modifications  to existing  hardware and
software,  and training which will be expensed as incurred. We also believe that
some of our telecommunication systems may not be Y2K compliant. We are currently
assessing these systems and, where material,  plan to replace, modify or upgrade
these systems, as appropriate, by the end of the second quarter of 1999.

     NON-INFORMATION TECHNOLOGY

     Non-information technology consists mainly of facilities management systems
such as telephone,  utility,  and security  systems for the corporate office and
owned  properties.   Based  on  our  current  efforts,  the  corporate  office's
non-information  technology is expected to be Y2K compliant by mid-1999.  We are
in the  process of  identifying  date  sensitive  systems and  equipment  at our
properties.  To date, we have not identified any critical non-compliant systems.
Assessment  and  testing of  non-information  technology  at our  properties  is
expected to be competed by mid-1999.

     THIRD PARTIES

     We have third-party relationships with tenants,  suppliers and contractors.
Many of these third  parties are  publicly  traded  corporations  and subject to
disclosure  requirements.  We have begun  assessment of major third parties' Y2K
readiness  including  tenants,  key suppliers of outsourced  services  including
stock transfer, debt servicing, banking collection and disbursement, payroll and
benefits,  while  simultaneously  responding  to their  inquiries  regarding our
readiness. The principal risks to us in our relationships with third parties are
the failure of third-party  systems used to conduct business such as (i) tenants
being unable to efficiently  conduct their business,  (ii) banks being unable to
process receipts and disbursements,  (iii) vendors being unable to supply needed
materials  and services to the  properties,  and (iv)  processing  of outsourced
payroll. Based on Y2K compliance work done to date, we have no reason to believe
that key tenants,  banks and suppliers will not be Y2K compliant in all material
respects or cannot be replaced within an acceptable time frame. Additionally, we
have obtained or are in the process of obtaining  compliance  certification from
suppliers of key services.

     We do not believe  that the impact of the Y2K problem  will have a material
adverse effect on our financial condition and results of operations. Such belief
is based on our  analysis  of our risks  related to both our own  potential  Y2K
problems  discussed above and our assessment of the Y2K problems of our vendors,
suppliers and customers. However, the description of our Y2K compliance is based
upon information obtained by management through evaluations of internal business
systems  from  inquiries  of key  tenants  and major  vendors  concerning  their
compliance  efforts.  If key tenants or major  vendors  with whom we do business
fail to adequately  address their Y2K issues,  our financial position or results
from operations could be materially adversely affected.

     We  currently  do not  have a  contingency  plan  in  place.  Once  we have
proceeded  further in the completion of steps outlined above,  contingency plans
will be developed.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

     In June 1998, the FASB issued Statement No. 133,  Accounting for Derivative
Instruments  and  Hedging  Activities,  which is required to be adopted in years
beginning  after June 15, 1999.  The Statement  permits early adoption as of the
beginning of any fiscal  quarter after its issuance.  We expect to adopt the new
Statement  effective January 1, 2000. The Statement will require us to recognize
all  derivatives  on the balance sheet at fair value.  Derivatives  that are not
hedges must be adjusted  to fair value  through  income.  If a  derivative  is a
hedge, changes in the fair value of the derivative will either be offset against
the change in fair  value of the hedged  asset,  liability,  or firm  commitment
through earnings,  or recognized in other comprehensive  income until the hedged
item is recognized in earnings. The ineffective portion of a derivative's change
in fair value will be immediately  recognized in earnings.  We do not anticipate
that the  adoption  of this  Statement  will  have a  significant  effect on our
results of operations or financial position.




                                      -26-
<PAGE>
INFLATION

     Substantially  all of our office and industrial  leases require  tenants to
pay, as  additional  rent,  a portion of any  increases in real estate taxes and
operating  expenses  over a base  amount.  In  addition,  many of the office and
industrial   leases  provide  for  fixed  increases  in  base  rent  or  indexed
escalations  (based on the Consumer Price Index or other  measures).  We believe
that inflationary  increases in expenses will be offset, in part, by the expense
reimbursements and contractual rent increases described above.

     As of December 31, 1998,  approximately  $310.6 million of our  outstanding
indebtedness  (including  our Credit  Facilities)  was  subject to  interest  at
floating  rates and future  indebtedness  may also be subject to  floating  rate
interest. Inflation, and its impact on floating interest rates, could affect the
amount of interest payments due on such indebtedness.

ITEM 7A. QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

     The following  table provides  information  about our derivative  financial
instruments  and other  financial  instruments  that are sensitive to changes in
interest  rates.  For our mortgage note  receivable,  mortgage notes payable and
bonds  payable (no amounts were drawn on our Credit  Facilities  at December 31,
1998),  the table  presents  principal  cash flows and related  weighted-average
interest rates by expected  maturity dates.  For treasury lock  agreements,  the
table   presents   notional   amounts  to  be  entered   into  and  the  related
weighted-average lock rate by the maturity dates.

     31,  1998 were  6.62% and 3.92%,  respectively.  If  interest  rates on our
     variable rate debt increased by one percentage  point,  our annual interest

(4)  At December 31, 1998, we made deposits  totaling  $14.6 million  related to
     treasury lock agreements of $170.0 million and $160.0  million,  which were
     to expire  in 1999.  The  average  lock rate  reflected  is based  upon the
     agreements in effect as of December 31, 1998 (5.364% for the $170.0 million
     agreement and 4.732% for the $160.0 million  agreement).  During the period
     from January 1, 1999  through  March 25,  1999,  we have  received net cash
     settlements  of  approximately  9.2 million  ($1.0  million  related to the
     $170.0  million  agreement,  $8.2  million  related to the  $160.0  million
     agreement).  On March 1, 1999, we terminated  the $160.0  million  treasury
     lock  agreement  due to the change in the terms and timing of the IBM Plaza
     purchase  as  a  result  of  the  amended   purchase   agreement   (we  had
     approximately  $0.6 million on deposit  related to this  agreement that was
     forfeited the time of the termination).

                         Report of Independent Auditors

Board of Trustees
Prime Group Realty Trust

     We have audited the accompanying consolidated balance sheets of Prime Group
Realty  Trust as of  December  31, 1998 and 1997,  and the related  consolidated
statements of operations, shareholders' equity and cash flows for the year ended
December 31, 1998 and for the period from  November 17, 1997 (date of formation)
through  December  31,  1997.  We have also  audited the  accompanying  combined
statements of operations,  changes in predecessors'  deficit,  and cash flows of
the  Predecessor  for the period from January 1, 1997 through  November 16, 1997
and for the year ended  December 31, 1996.  These  financial  statements are the
responsibility of Prime Group Realty Trust's and Predecessor's  management.  Our
responsibility  is to express an opinion on these financial  statements 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 Prime Group
Realty Trust at December 31, 1998 and 1997, and the consolidated  results of its
operations  and its cash flows for the year ended  December 31, 1998 and for the
period from November 17, 1997 through  December 31, 1997, and the  Predecessor's
combined results of operations and its cash flows for the period from January 1,
1997  through  November 16, 1997 and for the year ended  December  31, 1996,  in
conformity with generally accepted accounting principles.

                                                           /s/ ERNST & YOUNG LLP

                  PRIME GROUP REALTY TRUST AND THE PREDECESSOR

             NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS

        (Dollars in thousands, except for per share and per unit amounts)

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

FORMATION AND ORGANIZATION OF THE COMPANY

     Prime Group Realty Trust (the  "Company") was organized in Maryland on July
21, 1997 to continue the  business of The Prime  Group,  Inc. and certain of its
affiliates  (collectively  "PGI").  The  Company  qualified  as  a  real  estate
investment  trust  ("REIT")  beginning  with the period ended December 31, 1997,
under the Internal  Revenue  Code of 1986,  as amended,  for Federal  income tax
purposes.  On November  17,  1997,  the  Company  completed  its initial  public
offering with the sale of 12,380,000 of its common shares of beneficial interest
at $20.00 per share and the private  placement  of  2,000,000  of the  Company's
Series  A-cumulative  convertible  preferred  shares of  beneficial  interest at
$20.00 per share.  The Company  contributed  the initial net  proceeds  from the
offering  and private  placement  in exchange  for  12,380,000  common  units of
partnership  interest and 2,000,000  preferred units of partnership  interest in
Prime Group  Realty,  L.P.  (the  "Operating  Partnership").  Subsequent  to the
initial  public  offering,  the Company  issued an  additional  3,204,994 of its
common shares (sold 600,000 common shares in 1997, sold 2,579,994  common shares
in 1998  and  granted  25,000  shares  in  1998)  and  4,000,000  of its  Series
B-cumulative redeemable preferred shares and contributed the net proceeds to the
Operating  Partnership  in  exchange  for the same  number of  common  units and
preferred units of partnership interest.  In addition,  during 1998, the Company
repurchased  474,200 of its common  shares for an  aggregate  purchase  price of
$7,267, pursuant to a common share repurchase program the Company established in
September  1998.  (Repurchase  the lesser of  1,550,000  common  shares or spend
$7,500 with share prices not to exceed $20.00 per common share.)

     The Company is the managing  general  partner of the Operating  Partnership
and owns all of the  preferred  units and 59.4%  and 55.9% of the  common  units
issued at December 31, 1998 and 1997,  respectively.  Each common unit  entitles
the  Company  to  receive   distributions   from  the   Operating   Partnership.
Distributions  declared or paid to holders of common shares and preferred shares
are based upon such  distributions  the  Company  receives  with  respect to its
common units and preferred units.

     In conjunction  with the Company's  initial  contribution  to the Operating
Partnership,  PGI contributed its interest in 23 partnerships that owned various
office and industrial  properties  (represents the Predecessor's  operations) to
the  Operating   Partnership  in  exchange  for  3,465,000   common  units  (PGI
contributed  3,375,000 of these common units to Primestone  Investment  Partners
L.P. described below) and received approximately $6,487 for the reimbursement of
the Company's  formation  costs advanced by PGI. The Operating  Partnership  was
required  to  acquire  a  third-party  ownership  interest  in  certain  of  the
Predecessor's properties for $1,797, resulting in a step-up in the basis of real
estate  of  $3,227.  Certain  other  individuals   contributed  their  ownership
interests in various  properties,  including  the related debt, to the Operating
Partnership in exchange for cash of  approximately  $15,761 and 1,849,417 common
units  valued  at  $20.00  per unit  (total  value  of  $36,988).  In  addition,
Primestone  Investment Partners L.P., an entity in which PGI has a 60% ownership
interest,  acquired  4,569,893  common units from the Operating  Partnership for
$85,000  (PGI  directly  or  indirectly  owns  31.6% and 34.7% of the  Operating
Partnership  at December  31,  1998 and 1997,  respectively.)  These  properties
(including the Predecessor's properties),  along with other acquired properties,
are controlled by the Operating  Partnership.  PGI, the other  contributors  and
Primestone  Investment  Partners L.P. have been reflected as minority interest -
Operating Partnership in the consolidated financial statements.

BASIS OF PRESENTATION

     The  Company's   consolidated  financial  statements  include  all  of  its
accounts,  including,  the Operating Partnership and the other entities in which
the Company has control.  The combined  financial  statements of the Predecessor
include the accounts of the  partnerships  in which the Predecessor had majority
interest,  control or  managed.  The  preparation  of  financial  statements  in
conformity with generally accepted accounting  principles requires management to
make estimates and  assumptions  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 period. Actual results could differ from those estimates.

     Investments in corporations  and partnerships in which the Company does not
have operational  control or a majority interest are accounted for on the equity
method of accounting.

     Significant  intercompany accounts and transactions have been eliminated in
consolidation and combination.

     Certain  amounts in the prior period  consolidated  and combined  financial
statements have been reclassified to conform to the current period presentation,
with no effect  on the  Company's  consolidated  or the  Predecessor's  combined
financial position or results of operations.

     On  December  15,  1997,  the  Company  acquired  the first  mortgage  note
encumbering an office property known as Continental Towers for $108,870,  with a
face value of $157,161. On May 15, 1998, the Company sold $75,000 of the note to
a third-party bank and the note became  subordinate to the third-party note. The
note  has a base  interest  rate  of  6.5%  per  annum  payable  monthly,  and a
contingent interest rate of 6.5% per annum,  payable from available cash flow as
defined.  All unpaid  interest is added to principal.  The note matures  January
2013. The Company will receive all of the economic benefits from its interest in
the property and therefore, has consolidated the operations of the property from
the acquisition date.

     On November 17, 1997,  the  Operating  Partnership  acquired the assets and
business of two property  management and realty services  companies from a third
party and contributed  these entities and certain other assets to a newly formed
corporation,  Prime Group Realty  Services,  Inc. (the "Services  Company").  In
exchange for its contribution,  the Operating  Partnership  received 100% of the
non-voting  preferred stock of the Services Company and a note receivable in the
amount of $4,800 (See Note 10). Certain members of the Company's  management own
100% of the voting common stock.  The Services  Company was formed  primarily to
operate our business lines that are not directly  associated with the collection
of rents. The Services Company is subject to federal, state and local taxes. The
Company records its ownership in the Services Company using the equity method of
accounting.

REAL ESTATE

     Depreciation is calculated on the  straight-line  method over the estimated
useful lives of assets, which are as follows:

     Building and improvements                        40 years
     Tenant improvements                              Term of related leases
     Furniture and equipment                          3-7 years

     Development  costs,  which include land acquisition  costs,  fees and other
costs incurred in developing new properties,  are capitalized as incurred.  Upon
completion  of  construction,  development  costs are included in buildings  and
improvements  and are  depreciated  over  the  useful  lives  of the  respective
properties on a straight-line basis. Interest,  financing costs and other direct
costs incurred during development  periods are capitalized as a component of the
building costs.

     Real  estate is carried at  depreciated  cost.  Expenditures  for  ordinary
maintenance  and repairs are expensed to  operations  as  incurred.  Significant
renovations and improvements  which improve and/or extend the useful life of the
asset are capitalized and depreciated over their estimated useful life.

CASH EQUIVALENTS

     The Company  considers  highly liquid  investments with a maturity of three
months or less when purchased to be cash equivalents.

DEFERRED COSTS

     Costs  incurred  in  connection  with  financings,   refinancings  or  debt
modifications  are capitalized as deferred  financing costs and are amortized on
the  straight-line   method  over  the  lives  of  the  related  loans.  Leasing
commissions  and other leasing costs directly  attributable to tenant leases are
capitalized  as deferred  leasing costs and are  amortized on the  straight-line
method over the terms of the related lease agreements.

LEASES ASSUMED

     In  connection  with  certain  tenant  leases,  the Company has assumed the
liability  for the  remaining  terms of the  tenants'  existing  leases in their
previous  location.  The Company has  recorded a  liability  for the  difference

                                      F-11
<PAGE>
between total remaining costs for leases assumed and the expected  benefits from
subleases of the assumed lease  properties.  The related incentive to lessee has
been  capitalized as a deferred  charge and is being amortized to rental revenue
over the life of the respective lease. The deferred charge and related liability
are adjusted for changes in the expected  benefits  from  subleases.  During the
year ended  December  31,  1998,  the Company  assumed  additional  liability of
$1,357. During the period from January 1, 1997 through November 16, 1997 and for
the year ended December 31, 1996, the  Predecessor  wrote off $1,049 and $3,893,
respectively,  of deferred  charges and  reduced  the related  liability  due to
changes in the estimated  benefits from  subleases.  No amounts were written off
during the year ended  December 31, 1998 or during the period from  November 17,
1997 through December 31, 1997.

RENTAL REVENUE

     Rental  revenue is recorded on the  straight-line  method over the terms of
the related lease  agreements.  Differences  between  rental  revenue earned and
amounts due per the  respective  lease  agreements  are credited or charged,  as
applicable, to deferred rent receivable. Rental payments received prior to their
recognition as income are classified as rent received in advance.

TREASURY LOCK AGREEMENTS

     The Company uses  treasury  lock  agreements  to  synthetically  manage the
interest rate  characteristics of its outstanding debt to a more desirable fixed
or variable  rate basis or to limit the  Company's  exposure to rising  interest
rates.  Interest  rate  differentials  to be paid or  received  as a  result  of
treasury lock agreements are accrued and recognized as an adjustment of interest
expense  related  to the  designated  debt.  The fair  values of  treasury  lock
agreements are not recognized in the financial statements.

     Amounts  related  to  treasury  lock  agreement  deposits  (See Note 4) are
deferred and amortized as an  adjustment to interest  expense over the period of
interest  exposure,   provided  the  related  designated   long-term  borrowings
liability  continues  to  exist  or  is  probable  of  occurring.  Realized  and
unrealized  changes in fair value of treasury lock  agreements  designated  with
long-term borrowings that no longer exist or are no longer probable of occurring
are recorded as a component of the gain or loss arising from the  disposition of
the designated long-term borrowings.

EARNINGS PER SHARE

     Basic  earnings  per share  ("EPS") is  calculated  by dividing  net income
available  to  common  shareholders  by the  weighted  average  number of shares
outstanding  during the period.  Diluted EPS includes the  potentially  dilutive
effect,  if any, which would occur if outstanding  (i) common stock options were
exercised,  (ii) common units were converted into shares of common share,  (iii)
share  grants were  fully-vested,  and (iv)  convertible  preferred  shares were
converted into common shares.

STOCK BASED COMPENSATION

     The Company  accounts for share option grants in accordance with Accounting
Principles  Board  Opinion No. 25,  "Accounting  for Stock Issued to  Employees"
("APB 25").  Under APB 25, no  compensation  expense is recognized for the share
option grants  because the exercise price of the options equals the market price
of the underlying share at the date of grant.

INCOME TAXES

     Commencing  with the period ended December 31, 1997, the Company elected to
be taxed as a REIT under the  Internal  Revenue Code of 1986,  as amended.  As a
REIT,  the Company  generally  will not be subject to federal  income tax to the
extent  that it  distributes  at least  95% of its REIT  taxable  income  to its
shareholders.  REITs are subject to a number of  organizational  and operational
requirements. If the Company fails to qualify as a REIT in any taxable year, the
Company  will be  subject  to  federal  income  tax  (including  any  applicable
alternative minimum tax) on its taxable income at regular corporate tax rates.

     As of December 31, 1998, for income tax purposes, the Company's real estate
had a gross and net basis of $751,142 and $735,283 respectively,  mortgage notes
receivable had a basis of $172,149,  deferred costs had a gross and net basis of
$37,920 and $33,614 respectively, and deferred rent receivable had no tax basis.

     The  Predecessor  paid no  income  taxes,  and the  income or loss from its
partnerships   is  included  on  the  respective   income  tax  returns  of  the
Predecessor's partners.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

     In June 1998, the FASB issued Statement of Financial  Accounting  Standards
("SFAS") No. 133, Accounting for Derivative  Instruments and Hedging Activities.
The Company  expects to adopt the new Statement  effective  January 1, 2000. The
Statement  will require the Company to recognize all  derivatives on the balance
sheet at fair value.  The Company does not anticipate  that the adoption of this
Statement  will  have a  significant  effect on its  results  of  operations  or
financial position.

2.   MORTGAGE NOTE RECEIVABLE

     On December 16, 1997,  the Company  acquired for  approximately  $51,163 in
cash and $5,100 in common units,  the first mortgage note encumbering the office
property known as 180 North LaSalle Street, which is a 39-story office building,
located in Chicago, Illinois,  (containing 728,860 square feet of rentable space
and is  approximately  73.7% leased at December  31,  1998).  During  1998,  the
Company made additional advances of $4,943, which were used to fund improvements
to the  building and pay various  operating  expenses.  The Company  anticipates
providing additional advances of $11,600 to complete the building  improvements.
The note requires  principal  payments due at maturity on January 15, 2004.  The
note has a face value of $69,277  and  $62,518 at  December  31,  1998 and 1997,
respectively.

     The note provides for interest at an accrual rate of 9.64% per annum, and a
minimum  pay rate at the  lower of 8.25%  per  annum,  or  $2,400  annually,  as
defined,  payable  monthly.  During 1998, the Company  received  interest income
payments of $5,373.  No payments were  received  during the period from November
17, 1997 through December 31, 1997.  During the year ended December 31, 1998 and
the period from  November  17, 1997 through  December  31, 1997,  $258 and $248,
respectively, of interest income was added to the principal balance.

     Included in the purchase was a  non-refundable  option,  exercisable  until
July 30, 2000, to acquire the existing  $85,000 second  mortgage on the property
for  $4,400 in common  units  (annually  $1,200)  of the  Operating  Partnership
(amount  included in  minority  interest-operating  partnership),  valued at the
lower of $20.00 per unit or the Company's  common share price at the date issued
(5,000  common units if the  Company's  common share market value is equal to or
greater than $20.00 per share or $100 in common units per month if the Company's
common share market  value is below $20.00 per share;  67,018  common units were
issued during the year ended December 31, 1998), subject to certain adjustments,
as defined.  At December 31, 1998, $1,300 is included in other assets related to
the  options.  In  addition,  the Company  has an option to purchase  the equity
ownership  of the  property  during the period from January 15, 2004 to February
15,  2004 for a price  equal to the  greater  of the  fair  market  value of the
interest or $2,000.

     During 1998, the Company provided construction  management services of $752
to the property,  which have been added to the principal  balance.  The Services
Company  provides  property  management  and leasing  services  for the property
pursuant to a 10-year management and leasing contract.

(A)  The above  mortgage  notes  payable  and credit  facilities  are subject to
     various  operating  and  financial  covenants,  which  the  Company  is  in
     compliance with at December 31, 1998.

(B)  The majority of the  Company's  real estate  assets and its  mortgage  note
     receivable  have been pledged as collateral for its mortgage notes payable,
     credit facilities and bonds payable. In addition, the Company had a $12,000
     cash collateral account (amount included in restricted cash at December 31,
     1998) on  deposit  with a  financial  institution  related  to the  $80,000
     line-of-credit.  Subsequent  to December  31,  1998,  the Company  provided
     replacement collateral in the form of mortgages on two office buildings and
     the cash collateral account was released.

                                      F-14
<PAGE>

(C)  Permanent  financing for the development of certain  industrial  properties
     has been provided by $48,150 of tax exempt industrial  development  revenue
     bonds that mature on June 1, 2022.  On December  13,  1995,  and on May 20,
     1996,  the  bonds  were  acquired  by  independent  third  party  financial
     institutions from an affiliate of PGI.

     Under  the  terms  of  the  bond  loan   agreements,   the  Company   makes
     interest-only payments monthly, calculated using a floating rate determined
     by the remarketing agent of the bonds. The rates ranged from 2.97% to 4.50%
     during 1998, 3.35% to 4.75% during 1997 and 2.85% to 4.40% during 1996. The
     rate at December 31, 1998 was 4.13%.

     The  maximum  annual  interest  rate on the  bonds  is 13%.  Under  certain
     conditions, the interest rate on the bonds may be converted to a fixed rate
     at the Company's request.

     Beginning February 1998, the bonds were collateralized by letters of credit
     totaling  $48,800 from a financial  institution  which expire February 2002
     (the  bonds  become  due on this  date  unless  replacement  collateral  is
     obtained.)  The letters of credit are  collateralized  by  mortgages on the
     related industrial facilities and a $5,000 cash collateral account and have
     an annual fee of 1.4% of the letters of credit face amounts.  From November
     17, 1997 through February 1998, the bonds were collateralized by letters of
     credit totaling $48,000 from our $80,000  line-of-credit.  From May 1996 to
     November 16, 1997, the bonds were  collateralized by letters of credit that
     required the  Predecessor  to pay financing  fees of 1.75% per annum of the
     face amount, payable quarterly in advance.

     The  bondholders  may tender  bonds on any business day during the variable
     interest rate period  discussed above and receive  principal,  plus accrued
     interest through the tender date. Upon tender,  the remarketing  agent will
     immediately remarket the bonds. In the event the remarketing agent fails to
     remarket any bonds,  the Company is obligated to purchase those bonds.  The
     remarketing  agent  receives  a fee of 0.11% per  annum of the  outstanding
     bonds balance, payable quarterly in advance.

(D)  Permanent  financing for the  development of certain office  properties has
     been provided by $26,300 of tax-exempt  industrial revenue bonds. The bonds
     mature on December  1, 2014.  Under the terms of the bond  agreements,  the
     Company makes interest-only  payments monthly,  calculated using a floating
     rate  determined by the  remarketing  agent of the bonds.  The rates ranged
     from 3.40% to 4.00% during 1998,  3.35% to 3.85% during 1997,  and 3.40% to
     4.05% during 1996. The rate at December 31, 1998 was 3.55%.

     Under certain conditions,  the interest rates on the bonds may be converted
     to a fixed rate at the Company's request.

     The bonds are collateralized by letters of credit totaling $26,930 from our
     $80,000 line-of-credit,  which are subject to an annual fee of 2.25% of the
     amount outstanding.

     Under the terms of the bond agreements,  the bondholders have the option to
     require the  Company to purchase  any of their bonds on the 15th day of any
     month  while  the  bonds  are   outstanding.   Upon  the  exercise  of  the
     bondholders'  option to  purchase  the bonds,  the  remarketing  agent will
     immediately remarket the bonds. In the event the remarketing agent fails to
     remarket the bonds,  the Company is obligated to purchase those bonds.  The
     remarketing  agent  receives  a fee of 0.10% per  annum of the  outstanding
     bonds balance, payable quarterly in advance.

     During the year ended December 31, 1998, the Company wrote-off net deferred
     financing costs of $900, net of accumulated amortization of $32, related to
     mortgage notes and bonds payable that were repaid or refinanced  during the
     year,  $1,140,  net of accumulated  amortization  of $321, and $91 of other
     fees related to the  reduction in the maximum  balance that can be drawn on
     the $80,000 line-of-credit  (reduced from $235,000 to $80,000 during 1998).
     The total of these write-offs has been reflected as an  extraordinary  loss
     in the 1998 statement of operations,  net of amounts  allocated to minority
     interests of $878.


     The  Predecessor  had  entered  into  a  mortgage  note  agreement  with  a
consortium  of  commercial   lenders   providing  a  maximum  loan  of  $230,000
collateralized  by a first  mortgage on the 77 West Wacker Drive  building.  The
loan was repaid with proceeds from the initial public offering.  Under the terms
of the loan, the Predecessor  made monthly  interest-only  payments,  calculated

                                      F-15
<PAGE>
using  certain  variable  rate  indices,  as  defined.  To reduce  the impact of
increases in interest rates,  the Predecessor also entered into an interest rate
swap agreement with affiliates of one of 77 West Wacker Drive  building's  third
party owners  (Counterparties) for the outstanding loan principal balance. Under
the  terms  of the  interest  rate  swap  agreement,  the  Predecessor  paid the
Counterparties  interest  monthly  at  a  fixed  rate  of  10%  per  annum.  The
Predecessor was to receive monthly interest payments from the  Counterparties at
the  variable  rate and was then  responsible  for making the  monthly  interest
payments required under the terms of the loan. The Predecessor  incurred $692 of
fees  to  terminate  the  swap  agreement,  which  have  been  reflected  in the
extraordinary  item  extinguishment  of debt in the period from  January 1, 1997
through November 16, 1997.

     Total interest paid on the mortgage notes  payable,  credit  facilities and
bonds  payable was $32,204 and $1,855,  $25,731,  and $25,643 for the year ended
December 31, 1998, the period from November 17, 1997 through  December 31, 1997,
the period from  January 1, 1997 through  November  16,  1997,  and for the year
ended December 31, 1996, respectively.  During the year ended December 31, 1998,
the Company incurred interest expense of $33,399 of which $2,498 was capitalized
related to  development  projects (no interest was  capitalized  in the previous
periods.)

     On August 21, 1998, the Company into two treasury lock  agreements with two
financial  institutions to lock certain debt instruments at the interest rate on
ten-year  Treasury  Notes  effective  on the date of the  agreements  to provide
interest rate protection on future debt financings.  One of these agreements was
entered into in  anticipation of a planned future  securitization  of a $170,000
loan  related  to the 77 West  Wacker  Drive  building,  and had a lock  rate of
5.364%. The other agreement was entered into in anticipation of $160,000 in debt
related to the  acquisition  of IBM Plaza,  had a lock rate of 4.732% and was to
expire  on March  19,  1999.  The  Company  made  deposits  as  required  by the
agreements,  totaling approximately $14,641 at December 31, 1998 ($5,922 related
to the $170,000 agreement and $8,719 related to the $160,000  agreement),  which
are  included in other  assets in the  consolidated  financial  statements.  The
deposits  are  exclusive  of a $2,000  credit  threshold  described  below.  The
$170,000 agreement was to expire on February 18, 1999, but was extended to April
15,  1999.  At that time,  the lock rate was  modified  to 5.016% and the credit
threshold  reduced from $2,000 to $500. If the market rate on ten-year  Treasury
Notes falls below the locked rate and the  difference  between  $170,000 and the
calculated  notional amount is in excess of the credit threshold,  cash deposits
are required.  On March 1, 1999, the Company  terminated  the $160,000  treasury
lock  agreement due to the change in terms and timing of the IBM Plaza  purchase
as a result of the amended purchase agreement. Approximately $557 on deposit was
forfeited at the time of termination.  During the period January 1, 1999 through
March 24, 1999,  the Company  received  net cash  settlements  of  approximately
$9,215  ($1,053  related to the $170,000  agreement,  and $8,162  related to the
$160,000  agreement)  related to both treasury lock agreements.  If the yield on
U.S.  ten-year  Treasury Notes at settlement is less than the locked yield,  the
difference between $170,000 and the calculated notional amount will be amortized
over the terms of the future  debt  instruments  as an  adjustment  to  interest
expense.  The  Company  intends to  consummate  debt  transactions  equal to the
notional value of the remaining agreement.

     The following  represents the Company's future minimum  principal  payments
due  on  its  mortgage  notes  payable,  credit  facilities  and  bonds  payable
outstanding at December 31, 1998:

     The Predecessor had an 11% subordinate  loan agreement with affiliates of a
former  third  party owner of the 77 West Wacker  Drive  building  for a maximum
disbursement  amount of $60,000.  A portion of the loan was repaid ($4,895) with
proceeds of the initial public  offering,  and a portion was  considered  repaid
from  the swap  agreement  between  PGI and a third  party  related  to the loan
described  in Note 4 ($42,584  was  recorded as a  contribution  from PGI in the
period from January 1, 1997 through  November  17, 1997) and the  remainder  was
forgiven  ($67,847),  as of November 16, 1997 and included in the  extraordinary
item-extinguishment  of debt in the period from January 1, 1997 through November
16, 1997. The third party owner had provided a guarantee of 77 West Wacker Drive
building's  first  mortgage  note payable and charged the  Predecessor a standby
loan fee, as defined,  which was  included as a component  of interest  expense.
Standby  loan fees  incurred  were $460 for the period  from  January 1, 1997 to
November  16,  1997 and  $522 for the year  ended  December  31,  1996,  (unpaid
interest  expense is  included  in general  and  administrative  expenses in the
Predecessor's  combined  statements  of  operations).  Under  the  terms  of the
subordinate  loan  agreement,  the  Predecessor  was not  required  to make  any
periodic  principal or interest payments prior to the date of stabilization,  as
defined; unpaid interest was added to the principal balance monthly. Included in
the extraordinary item-extinguishment of debt in the period from January 1, 1997
through  November  16,  1997 is  $1,000  in  loan  termination  fees  paid to an
affiliate  of the third party owner and the  write-off of  unamortized  deferred
financing fees of $165.

     Permanent  financing for the development of certain  industrial  properties
has been  provided by $12,000 of taxable  debt  industrial  development  revenue
bonds and held by an  affiliate  of PGI.  The bonds  mature on June 1, 2022.  On
November 17, 1997, PGI contributed  the related bond  receivables as part of its
contribution  to  us.  The  bonds  payable  and  related  receivable  have  been
eliminated in the Company's  consolidated  financial statements.  The bonds have
the same terms as the bonds described in letter (C) of Note 4.

     Total  interest  paid on the mortgage  notes  payable and bonds  payable to
affiliates was $33, $32 and $1,256 for the year ended December 31, 1998, for the
period from  January 1, 1997  through  November  16, 1997 and for the year ended
December  31,  1996,  respectively.  No  interest  was paid for the period  from
November 17, 1997 to December 31, 1997.

6.   FUTURE MINIMUM LEASE INCOME AND PAYMENTS

     The Company has entered into lease agreements with tenants with lease terms
ranging from one year to twenty years. The leases generally  provide for tenants
to share in increases  in operating  expenses and real estate taxes in excess of
specified base amounts.

     Approximately  16%, 39%, 57%, and 60%, of rental revenue for the year ended
December 31, 1998, the period from November 17, 1997 through  December 31, 1997,
the period from  January 1, 1997 through  November  16,  1997,  and for the year
ended  December 31, 1996,  respectively,  was received  from four tenants  (only
three of these  tenants for the year ended  December 31, 1998 and for the period
from November 17, 1997 through December 31, 1997).

     The total future  minimum  rentals to be received by the Company under such
noncancelable  operating  leases in effect at December  31,  1998,  exclusive of
tenant reimbursements and contingent rentals, are as follows:

     Future minimum  rentals include amounts to be received from PGI and certain
affiliates totaling $4,738.

     In  addition,  as a part of lease  agreements  entered  into  with  certain
tenants, the Company assumed the tenants' leases at their previous locations and
subsequently  executed subleases for certain of the assumed lease space.  Future
minimum rental payments to be paid by the Company under leases  assumed,  net of
subleases executed through December 31, 1998, are as follows:

</TABLE>

     During the year ended  December  31,  1998,  the Company  recognized  lease
termination income of $4,124, which is included in rental revenue.

     During  1995,  a tenant of the 77 West Wacker  Drive  building  experienced
financial difficulties and in 1997 defaulted on certain 1997 rental payments. As
a result of the default,  the  Predecessor  as of December  31, 1996,  wrote-off
$3,081 of deferred tenant costs, representing $940 of tenant receivables related
to straight-lining of the tenant's rental revenue and $2,141 of deferred leasing
costs.  In early November 1997,  the  Predecessor  reached an agreement with the
tenant to  terminate  the lease.  During the period from January 1, 1997 through
November 16, 1997, the Predecessor  recognized  revenue from this tenant only to
the extent cash was received.

7.   PREFERRED SHARES

     The Company is authorized to issue up to 30,000,000 of non-voting preferred
shares of  beneficial  interest in one or more series.  At December 31, 1998 and
1997, the Company had 2,000,000 Series A-Cumulative Convertible Preferred Shares
of beneficial  interest  ("Series A - preferred  shares") with a $0.01 par value
designated,  issued and outstanding.  On June 5, 1998, the Company completed the
sale of 4,000,000 Series B-Cumulative  Redeemable Preferred Shares of beneficial
interest  ("Series B -  preferred  shares")  with a $0.01 par value,  which were
designated issued and outstanding at December 31, 1998.

     Distributions on the Series  B-preferred shares are payable quarterly on or
about the last day of January, April, July and October of each year, at the rate
of 9% (equivalent to $2.25 per annum per Series  B-preferred  share). The Series
B-preferred  shares  rank  senior to the  Company's  common  shares and Series A
preferred  shares as to the payment of dividends and as to the  distribution  of
assets. On and after June 5, 2003, the Series B-preferred shares may be redeemed
at the Company's  option at a redemption  price of $25.00 per share plus accrued
and unpaid  distributions.  The  redemption  price is payable  solely out of the
proceeds from the sale of other Company capital shares of beneficial interest.





                                      F-18
<PAGE>
     Distributions on the Series  A-preferred shares are payable quarterly on or
about the last day of March,  June,  September  and December of each year,  at a
rate of 7.5%  (Equivalent  of $1.50  per  annum  per  Series  A-preferred  share
starting November 17, 1998, prior to November 17, 1998,  equivalent of $1.40 per
annum per Series A -  preferred  share.).  The Series  A-preferred  shares  rank
senior to the  Company's  common shares as to the payment of dividends and as to
the distribution of assets.  Series  A-preferred  shareholders can convert their
preferred shares into the Company's  common shares based on a conversion  price,
as defined.  The Company has the option to redeem the Series  A-preferred shares
beginning on and after  November 17, 2007,  in cash equal to the original  issue
price ($20.00) plus any accrued and unpaid dividends.  The holders of the Series
A-preferred  shares  have the  right  to elect  two  additional  members  to the
Company's Board of Directors if the equivalent of two quarterly dividends are in
arrears.  Each of such two directors  will be elected to serve until the earlier
of: (1) the election and qualification of such directors' successor,  or (2) the
payment of the dividend arrearage.

9.   EMPLOYEE BENEFIT PLANS

     On November 17, 1997, the Company  established a Share  Incentive Plan (the
"Plan") which permits the grant of stock  options,  stock  appreciation  rights,
restricted  stock,  restricted units and performance units to officers and other
key  employees  and to officers and  employees of  subsidiaries,  the  Operating
Partnership,  the Services Company and other-owned  partnerships.  The Plan also
permits the grant of stock options to non-employee Trustees.

     Under the Plan,  up to  1,850,000  of the  Company's  common  shares may be
issued or transferred to  participants.  The maximum  aggregate number of common
shares and share  equivalent  units that may be subject to awards granted during
any calendar year to any one participant under the Plan,  regardless of the type
of  awards,  is  200,000.   This  limit  applies   regardless  of  whether  such
compensation is paid in common shares or share equivalent units.

     Under the Plan, each of the seven Trustees as of November 17, 1997 received
options to acquire 5,000 of the Company's common shares at $20.00 per share (the
closing price on the day of the grant of the options).  Stock options granted to
the  Trustees  have a term of 10 years and will vest and be  exercisable  at the
rate of 33.3% per year over three years  commencing on the first  anniversary of
their date of grant.

     The Company's Board of Directors (the "Board") administers the Plan and has
the  authority  to  determine,  among  other  things,  subject  to the terms and
conditions of the Plan,  the  individuals  to be granted  options,  the exercise
price at which shares may be acquired,  the number of shares subject to options,
the vesting  requirements  and the exercise period of each option.  The Board is
granted  discretion to determine the term of each option  granted under the Plan
to employees,  executives and Trustees, but in no event will the term exceed ten
years and one day from the date of the  grant.  The Board has  delegated  to the
Compensation Committee of the Board the authority take to such actions on behalf
of the full Board. On November 17, 1997, the Board granted options to purchase a
total of 1,160,500 of the Company's common shares  (including the 75,000 options
granted to Board  members  described  below) at an exercise  price of $20.00 per
share to various executives and employees of the Company. During 1998, the Board
granted options to purchase a total of 132,000  (exclusive of options  described
below as part of the Company's  annual incentive award program) of the Company's
common  shares at exercise  prices  ranging from $14.00 to $21.00 per share (the
closing  price on the day before the grant of the options) to various  employees
and  executives  of the Company  hired  during 1998.  In addition,  during 1998,
117,500  options  expired  as the result of  employees  or  executive,  who held
options,  resigning  from the Company  (exercise  prices  ranging from $20.00 to
$20.44 per share). Options for these shares granted under the plan to executives
and  employees  have a term of 10  years  and  will be  exercisable  and vest in
installments  as follows:  (i) 33.3% of the number of shares  commencing  in the
first  anniversary of the date of grant; (ii) an additional 33.3% for the shares
commencing  on the second  anniversary  of the date of the grant;  and (iii) the
remainder  of the  shares  commencing  on the third  anniversary  of the date of
grant.

     Under a  consulting  agreement  with one of the  members of the Board,  the
Board granted on November 17, 1997,  options to purchase 75,000 of the Company's
common  shares  at an  exercise  price of  $20.00  per  share.  Pursuant  to the
agreement,  the options  granted have a term of 10 years and will be exercisable
and vest at the rate of 33.3% per year over three years  commencing on the first
anniversary of their date of grant.

     During 1998,  the Company issued a total of 22,500 common shares granted to
two of its officers and 2,500 common shares  granted to one of its Board members
pursuant to their employment agreements or consulting agreement,  as applicable,
valued at the market price of the Company's  common shares at the date of grant,
totaling $458.

     As part of an annual  incentive  award  program,  on December 17, 1998, the
Board granted certain  executives  25,694 shares of the Company's  common shares
and options to purchase  538,889 of the  Company's  common shares at an exercise

                                      F-20

price of $14.00 per share.  The common share grants vest 50% on January 15, 1999
and 50% on January  15, 2000 and the options  vested on January  15,  1999.  The
Board  also  granted  certain  executives  options  to  purchase  254,000 of the
Company's common shares,  at an exercise price of $14.00 per share, as part of a
long-term  incentive  program.  These options vest at the rate of 25.0% per year
over four years  commencing on January 15, 1999. As the total options granted to
date exceed that  authorized  under the plan,  the excess options are subject to
the Company's shareholders' approval.

     The unaudited pro forma  information  regarding net income and earnings per
share is required by SFAS No. 123,  "Accounting for  Stock-Based  Compensation",
and has been  determined  as if the Company had  accounted for its options under
the fair value  method of that  statement.  The fair value for the  options  was
estimated at the date of grant using a  Black-Scholes  option pricing model with
the following weighted average assumptions for 1998 and 1997; respectively, risk
free interest rate of 5.01% in 1998 and 5.41% in 1997,  expected  dividend yield
of 6.7%;  volatility  factor of the expected market price of our common stock of
0.339 in 1998 and 0.156 in 1997;  and a  weighted-average  expected  life of the
options of three years for both  periods.  The unaudited pro forma expense would
be $1,174 ($0.08 per basic and diluted common share) for the year ended December
31, 1998 and $69 ($0.01 per basic and diluted  common share) for the period from
November 17, 1997 through  December 31, 1997. The effects on unaudited pro forma
net income and pro forma  earnings per common share for the year ended  December
31, 1998 and for the period  from  November  17,  1997 to  December  31, 1997 of
amortizing  to  expense  the  estimated  fair  value  of stock  options  are not
necessarily representative of the effects on net income to be reported in future
years due to such things as the  vesting  period of the stock  options,  and the
potential for issuance of additional stock options in future years. For purposes
of pro forma  disclosures,  the estimated fair value of the options is amortized
to expense over the options' vesting period.

     The  Black-Scholes  options  valuation  model  was  developed  for  use  in
estimating the fair value of traded  options which have no vesting  restrictions
and are fully  transferable.  In addition,  option  valuation models require the
input of highly  subjective  assumptions  including  the  expected  stock  price
volatility.  Because changes in the subjective input  assumptions can materially
affect the fair value estimate, in the Company's management opinion the existing
models do not necessarily provide a reliable single measure of the fair value of
the options granted under the plan.

     The  following is a summary of the  Company's  stock option  activity,  and
related information for the year ended December 31, 1998 and for the period from
November 17, 1997 through December 31, 1997 follows:

11.  FAIR VALUES OF FINANCIAL INSTRUMENTS

     SFAS No. 107,  "Disclosures About Fair Value of Financial  Instruments" and
SFAS No. 119, "Disclosure about Derivative Financial  Instruments and Fair Value
of Financial Instruments" require disclosure of the fair value of certain on-and
off-balance sheet financial instruments for which it is practicable to estimate.
Fair value is  defined  by SFAS No.  107 as the  amount at which the  instrument
could be exchanged in a current transaction between willing parties,  other than
in a forced or liquidation sale.

     The Company used the following  methods and  assumptions  in estimating the
fair value disclosures for financial instruments.

CASH AND CASH EQUIVALENTS AND RESTRICTED CASH ESCROWS

     The  carrying  amount  of cash and cash  equivalents  and  restricted  cash
escrows reported in the  consolidated  and combined balance sheets  approximates
their fair value.

     The Company  maintains its cash and cash  equivalents  and restricted  cash
escrows at various financial institutions. The combined account balances at each
institution  periodically exceed FDIC insurance coverage, and as a result, there
is a  concentration  of credit  risk  related to amounts on deposit in excess of
FDIC insurance coverage. The Company believes that the risk is not significant.




                                      F-23
<PAGE>
MORTGAGE NOTES PAYABLE, CREDIT FACILITIES AND BONDS PAYABLE

     The carrying  amount of the  Company's  variable and fixed rate  borrowings
(including  accrued  interest)  approximates  fair  value  based on the  current
borrowing rate for similar types of borrowing arrangements.

12.  COMMITMENTS AND CONTINGENCIES

     The  Company is a  defendant  in legal  actions  arising  during the normal
course of business.  The Company  believes  that the  ultimate  outcome of those
actions will not materially affect its consolidated financial position.

     All  of the  Company's  properties  were  subject  to  Phase  I or  similar
environmental  assessment by independent  environmental  consultants  which were
intended to discover  information  regarding,  and to evaluate the environmental
condition of, the surveyed property and surrounding  properties.  The Company is
aware of contamination at certain of the industrial  properties  included in the
Predecessor  properties,  which are already in remediation programs sponsored by
the state in which  they are  located.  The Phase I  assessments  estimate  that
remedial action plans will have a probable cost of approximately  $3,205. During
1997, PGI initiated  lawsuits  against a former  environmental  consultant and a
former  tenant of one of these  properties  for damages to cover the cost of the
remedial  action plans.  During 1997,  the  Predecessor  recorded a liability of
$3,205  (included in accounts  payable and accrued expenses at December 31, 1998
and 1997).  PGI has  contractually  agreed to  indemnify  the  Company  from any
environmental  liabilities  the Company may incur.  On February  20,  1998,  PGI
reached an agreement  with the former  tenant and  received a $1,822  settlement
payment. The Company is also aware of contamination at two other properties; one
of the  properties the tenant has provided the Company with an indemnity for all
the cost associated with the environmental  remediation,  the second property is
in the remediation  program sponsored by the state in which it is located with a
remedial  action plan and the  previous  owner has  provided the Company with an
escrow  account of $760  (maximum  cost the  previous  owner has agreed to pay),
which the Company will use in the clean-up of the property.

     On July 22,  1998,  the Company  entered  into a purchase  agreement,  with
affiliates of a limited partner of the Operting  Partnership (the "Sellers"), to
acquire two office buildings, IBM Plaza (a 1,354,354 square foot office building
located in the Chicago  central  business  district) and National City Center (a
766,965  square  foot  office  building  located  in  Cleveland,  Ohio),  for an
aggregate purchase price of approximately  $357,000.  On September 15, 1998, the
Company  terminated the purchase  agreement in accordance  with the terms of the
agreement,  because  the Sellers were  unable to  satisfy a  material  condition
precedent  to the closing of these  acquisitions.  On September  21,  1998,  the
Sellers notified the Company in writing that they believed they were entitled to
the $20,000  (amount  included in restricted  cash at December 31, 1998) earnest
money  provided for by the  agreement,  and  instructed the earnest money escrow
agent to draw the full amount  under two  earnest  money  letters-of-credit  the
Company provided under one of the Credit Facilities,  and also filed a complaint
against the Company alleging that it breached the contract. On October 30, 1998,
the  Company  filed its answer to the above  complaint  and denied all  material
allegations of the complaint.  The Company also filed a counterclaim against the
Sellers alleging that the Sellers breached the contract and sought the return of
the above  mentioned  earnest money and other damages.  On February 5, 1999, the
Company entered into an amended purchase  agreement and an option agreement with
the Seller with the following terms:

     -    Both the  original  lawsuit  filed  by the  Sellers and the  Company's
          counterclaim were dismissed.

     -    The Company  purchased  National City Center on February 5, 1999 for a
          contract price of $100,000.

     -    The $20,000  earnest money escrow was released and the Company used it
          to  fund  the   purchase  of  National   City  Center  and  an  $8,000
          nonrefundable payment for the option to purchase IBM Plaza. The option
          provides  the Company with the  opportunity  to purchase IBM Plaza for
          $230,000 (exclusive of the $8,000  nonrefundable  deposit) and expires
          October 31,  1999.  If the option is  exercised,  the  purchase of the
          property must be completed no later than December 20, 1999.

     The  Company has  contracts  to acquire  parcels of land and an  industrial
property from  affiliates of a member of the Board for a total purchase price of
approximately  $20,856,  $12,284 of which is payable  in  Operating  Partnership
common units.  The contracts  require the Company to acquire minimum portions of
the land on an annual basis until all of the parcels are acquired by 2002.


                                      F-24
<PAGE>
     During 1998, the Company entered into contracts to acquire three parcels of
land totaling 233.5 acres,  of which 100.8 acres was purchased in June 1998. The
remaining 132.7 acres must be purchased,  at the Company's discretion,  over the
next three to five years for approximately  $11,224.  The Company is required to

15.  SEGMENT REPORTING

     The  Company  adopted  SFAS No.  131,  "Disclosures  about  Segments  of an
Enterprise and Related Information", during the fourth quarter of 1998. SFAS No.
131 established  standards for reporting information about operating segments in
annual financial  statements and requires  selected  information about operating
segments in interim financial reports issued to shareholders. Operating segments
are  defined as  components  of an  enterprise  about which  separate  financial
information  is  available  that is evaluated  regularly by the chief  operating
decision maker, or decision making group, in deciding how to allocate  resources
and in assessing  performance.  The Company's  chief  operating  decision makers
manage  its  operating  segments   separately  because  each  operating  segment
represents  a  strategic  business  unit  that has  different  issues  and serve
different  markets.  The Company's  reportable  operating  segments  include its
office division and industrial division,  with properties principally located in
the mid-western  portion of the United States.  The Company evaluates its office
and industrial divisions operations principally on their contribution to overall
net income and funds from operations.

     The following summarizes the Company's historical segment operating results
for the year ended  December 31, 1998 and for the period from  November 17, 1997
through December 31, 1997:

(1)  The  Company  funded a portion of the  acquisition  costs  with  $30,000 in
     advances from its credit facilities (See Note 4).

(2)  Acquisition  costs and mortgage  debt  include  $2,044 to adjust an assumed
     above mortgage rate mortgage note payable to a current market rate.

(3)  These  properties were acquired from minority  interest unit holders of the
     Operating Partnership or their affiliates.

On February  8, 1999,  the Company  signed a contract  with a buyer  pursuant to
which it will  construct  an  approximately  1,018 space  parking  garage,  with
approximately 4,000 square feet of retail space, on approximately  22,000 square
feet of land that the  Company  has  under  option to  purchase  in the  Chicago
central business district,  and sell the completed parking garage to such buyer.
The sales price is  approximately  $34,600,  plus the value of any of the retail
space  leased by the  Company at the time of sale up to a maximum of $4,000.  In
addition,  the Company is entitled  to an  additional  $1,000 from the buyer if,
within 15 years after the sale of the parking  garage to the buyer,  the Company
substantially  completes an office  building  containing at least 800,000 square
feet of  office  space,  which is  occupied  by at least one  tenant  who is not
affiliated with the Company.  The Company has acquired this land with the intent
to construct an office  building which the Company will own for lease.  The land
parcel for the office building could not be obtained without  obtaining the land
for the parking  garage and in order to  construct an office  building,  parking
must be provided pursuant to zoning requirements.

       SCHEDULE III - REAL ESTATE AND ACCUMULATED DEPRECIATION (CONTINUED)
                             AS OF DECEMBER 31, 1998
                             (Dollars in Thousands)

(1)  The Company has a $20,000 mortgage note payable that is collateralized by a
     mortgage  note  receivable  and a $13,500  mortgage  note  payable  that is
     collateralized by property under  development.  See Note 4 to the Company's
     consolidated  financial  statements for a description of its mortgage notes
     payable, credit facilities and bonds payable.

(2)  Depreciation is calculated on the  straight-line  method over the estimated
     useful lives of assets, which are as follows:
         Building  and  improvements                  40 years
         Tenant improvements                          Term of related leases
         Furniture and equipment (included in
            buildings and improvements)               3-7 years

(3)  These  properties  are  collateral  for $90,500 in various  mortgage  notes
     payable.

(4)  These properties are collateral for a $80,000 line-of-credit,  which had no
     amount drawn at December 31, 1998.

(5)  These properties are collateral for letters-of-credit  that support certain
     industrial revenue bonds on other properties reflected in this table.

(6)  This  property is  collateral  for a $15,000  line-of-credit,  which had no
     amount drawn at December 31, 1998.


     The aggregate  gross cost of the  properties  included  above,  for federal
income tax purposes,  approximated $751,142 as of December 31, 1998. The Company
has $51,376 in property under development at December 31, 1998, all of which was
added during 1998 (same basis for federal income tax purposes).

     The  following  table  reconciles  our  historical  cost for the year ended
December 31, 1998 and for the period from November 17, 1997 through December 31,
1997.

elapsed  in the  period  for  which  the  calculation  is being  made by (b) the

outstanding principal balance.

     2.2.3 DETERMINATION OF INTEREST RATE.

     (a) Subject to the terms and  conditions  of this  Section  2.2.3  Borrower
shall pay interest on the outstanding principal amount of the Loan at LIBOR plus
one hundred  (100) basis points for each Interest  Period  following the initial
Interest Period.  Each  determination by Lender of the Applicable  Interest Rate

     (b)  If  any   requirement   of  law  or  any  change  therein  or  in  the

<PAGE>
contemplated hereunder and such unlawfulness cannot be avoided by Lender through
reasonable  efforts,  Lender shall, by notice to Borrower  ("Lender's  Notice"),
offer to establish an interest rate at Lender's then  customary  spread,  taking
into account the size of the Loan,  the Net  Operating  Income from the Property
and the creditworthiness of Borrower,  above a published index used for variable
rate loans as  reasonably  determined  by Lender  (the  "Substitute  Rate").  By
written notice to Lender within thirty (30) days of receipt of Lender's  Notice,
Borrower may accept such offer in which case the Applicable  Interest Rate shall
be a rate equal to the  Substitute  Rate in effect  from time to time until such
illegality  or  condition   shall  cease  to  exist,   in  Lender's  good  faith
determination.  If Borrower  does not timely accept such offer,  interest  shall
accrue at the  Substitute  Rate and Borrower  shall,  within ninety (90) days of
Lender's  Notice,  pay to  Lender  on a  Payment  Date  the  entire  outstanding
principal of the Loan,  the accrued and unpaid  interest  and all other  amounts
then due and payable under the Loan.

     (c) In the event that Lender  shall have  determined  (which  determination
shall be conclusive and binding upon Borrower absent manifest error) that (a) by
reason of circumstances  affecting the interbank eurodollar market, adequate and
reasonable means do not exist for ascertaining the LIBOR rate, and (b) the LIBOR
rate  determined  pursuant to the terms and provisions of this Agreement for the
Interest  Period  does not  accurately  reflect  the cost to Lender of making or
maintaining the amount of the Loan, then Lender shall by a Lender's Notice offer
a  Substitute  Rate.  By written  notice to Lender  within  thirty  (30) days of
receipt of  Lender's  Notice,  Borrower  may accept such offer in which case the
Libor Rate shall be a rate equal to the  Substitute  Rate in effect from time to
time until such  circumstances  shall  cease to exist,  in  Lender's  good faith
determination.  If Borrower  does not timely accept such offer,  interest  shall
accrue at the  Substitute  Rate and Borrower  shall,  within ninety (90) days of
Lender's  Notice,  pay to  Lender  on a  Payment  Date  the  entire  outstanding
principal of the Loan,  the accrued and unpaid  interest  and all other  amounts
then due and payable under the Loan.

     (d) Borrower  agrees to indemnify  Lender and to hold Lender  harmless from
any loss or expense which Lender  sustains or incurs as a consequence of (i) any
default by  Borrower  in payment of the  principal  of or  interest at the LIBOR
rate,  including,  without  limitation,  any such loss or expense  arising  from
interest or fees  payable by Lender to lenders of funds  obtained by it in order
to maintain the Loan at the LIBOR rate, (ii) any prepayment  (whether  voluntary
or mandatory) of the Loan on a day that (A) is not the Payment Date  immediately
following the last day of an Interest  Period with respect thereto or (B) is the
Payment  Date  immediately  following  the last day of an  Interest  Period with
respect  thereto  if  Borrower  did not give the  prior  written  notice of such
prepayment required pursuant to the terms of this Agreement,  including, without
limitation, such loss or expense arising from interest or fees payable by Lender
to lenders of funds obtained by it in order to maintain the LIBOR rate hereunder
and (iii) the  conversion  (for any  reason  whatsoever,  whether  voluntary  or
involuntary) of the Applicable Interest Rate to the Substitute Rate,  including,
without limitation,  such loss or expenses arising from interest or fees payable
by Lender to lenders of funds  obtained by it in order to  maintain  the Loan at
the LIBOR  rate (the  amounts  referred  to in clauses  (i),  (ii) and (iii) are
herein  referred to  collectively  as "Breakage  Costs").  This provision  shall
survive  payment  of the  Note  in  full  and  the  satisfaction  of  all  other
obligations of Borrower under this Agreement and the other Loan Documents.

     2.2.4  PAYMENTS OF INTEREST.  Borrower shall pay to Lender (a) on the first
Payment Date following the Closing Date, an amount equal to interest only on the
outstanding  principal  balance of the Loan from the Closing  Date up to but not
including  such Payment Date and (b) on each Payment Date  thereafter  up to but
not  including  the  Maturity  Date,  an amount  equal to  interest  only on the
outstanding  principal balance of the Loan from the prior Payment Date up to but
not including such Payment Date, in each case  calculated in accordance with the
provisions of this Section 2.2.

     2.2.5  PAYMENT  ON  MATURITY  DATE.  Borrower  shall  pay to  Lender on the

continuance of an Event of Default,  (a) interest on the  outstanding  principal
balance of the Loan and, to the extent  permitted by law,  overdue  interest and
other  amounts due in respect of the Loan,  shall  accrue at the  Default  Rate,
calculated  from the date such  payment was due  without  regard to any grace or




                                      -8-
<PAGE>
cure  periods  contained  herein and (b) Lender shall be entitled to receive and
Borrower  shall pay to Lender on each  Payment  Date an amount  equal to the Net
Cash Flow After Debt Service for the prior  month,  such amount to be applied by
Lender to the payment of the Debt in such order as Lender shall determine in its
sole discretion, including, without limitation, alternating applications thereof
between  interest and principal.  Interest at the Default Rate and Net Cash Flow
After Debt Service  shall both be computed  from the  occurrence of the Event of
Default  until the actual  receipt and  collection  of the Debt (or that portion
thereof that is then due). To the extent  permitted by applicable law,  interest
at the Default Rate shall be added to the Debt,  shall itself accrue interest at
the same rate as the Loan and shall be secured by the Mortgage.  This  paragraph
shall not be  construed  as an  agreement or privilege to extend the date of the
payment of the Debt,  nor as a waiver of any other  right or remedy  accruing to
Lender by reason of the  occurrence of any Event of Default;  the  acceptance of
any payment of Net Cash Flow After Debt  Service  shall not be deemed to cure or
constitute a waiver of any Event of Default; and Lender retains its rights under
this Note to accelerate  and to continue to demand  payment of the Debt upon the
happening  of any Event of  Default,  despite any payment of Net Cash Flow After
Debt Service.

     2.2.7 LATE PAYMENT CHARGE. If any principal, interest or any other sums due
under the Loan Documents is not paid by Borrower on the date on which it is due,
Borrower  shall pay to Lender upon demand an amount  equal to the lesser of five
percent (5%) of such unpaid sum or the maximum  amount  permitted by  applicable
law in order to defray the expense incurred by Lender in handling and processing
such delinquent payment and to compensate Lender for the loss of the use of such
delinquent  payment.  Any such amount  shall be secured by the  Mortgage and the
other Loan Documents to the extent permitted by applicable law.

     2.2.8 USURY SAVINGS. This Agreement and the Note are subject to the express
condition  that at no time  shall  Borrower  be  obligated  or  required  to pay
interest  on the  principal  balance of the Loan at a rate which  could  subject
Lender to either  civil or criminal  liability as a result of being in excess of
the Maximum  Legal Rate.  If, by the terms of this  Agreement  or the other Loan
Documents,  Borrower is at any time required or obligated to pay interest on the
principal  balance due  hereunder at a rate in excess of the Maximum Legal Rate,
the  Applicable  Interest Rate or the Default Rate, as the case may be, shall be
deemed to be  immediately  reduced to the  Maximum  Legal Rate and all  previous
payments  in  excess  of the  Maximum  Legal  Rate  shall be deemed to have been
payments  in  reduction  of  principal  and not on account of the  interest  due
hereunder.  All  sums  paid  or  agreed  to be  paid  to  Lender  for  the  use,
forbearance,  or detention of the sums due under the Loan,  shall, to the extent
permitted by  applicable  law, be  amortized,  prorated,  allocated,  and spread
throughout  the full stated  term of the Loan until  payment in full so that the
rate or amount of  interest  on account of the Loan does not exceed the  Maximum
Legal Rate of interest  from time to time in effect and  applicable  to the Loan
for so long as the Loan is outstanding.

     Section 2.3 PREPAYMENTS.

     2.3.1 VOLUNTARY PREPAYMENTS.  Borrower may, at its option and upon ten (10)
Business Days prior written  notice from Borrower to Lender,  prepay in whole or
in part the Debt without  payment of any  prepayment  premium or  consideration.
Such payment,  if not paid on a Payment Date,  shall include interest that would
have accrued on such prepayment through the next Payment Date and any applicable
Breakage Costs.

     2.3.2  MANDATORY  PREPAYMENTS.  On each  date on  which  Borrower  actually

(b) there  exists no  structural  or other  material  defects  or damages in the
Property,  whether latent or otherwise, and (c) Borrower has not received notice
from any insurance  company or bonding company of any defects or inadequacies in
the Property, or any part thereof, which would adversely affect the insurability
of the same or cause the imposition of extraordinary premiums or charges thereon
or of any  termination  or threatened  termination of any policy of insurance or
bond.

     4.1.25  BOUNDARIES.  As evidenced by the Survey (a) all of the improvements
which were  included in  determining  the  appraised  value of the  Property lie
wholly within the boundaries and building restriction lines of the Property, and
no improvements on adjoining  properties encroach upon the Property,  and (b) no
easements  or other  encumbrances  upon the  Property  encroach  upon any of the

those which are insured against by title insurance.

     4.1.26  LEASES.  The  Property is not subject to any Leases  other than the
Leases described in Schedule I attached hereto and made a part hereof. No Person
has any  possessory  interest in the Property or right to occupy the same except
under and pursuant to the  provisions of the Leases.  The current  Leases are in
full force and effect and,  to the best of  Borrower's  knowledge,  there are no
defaults  thereunder  by either party  except as  disclosed  to Lender.  No Rent
(including  security  deposits) has been paid more than one (1) month in advance
of its due date.  All work to be performed by Borrower under each Lease has been
performed as required and has been accepted by the  applicable  tenant,  and any
payments,  free rent,  partial rent, rebate of rent or other payments,  credits,
allowances  or  abatements  required  to be given by  Borrower to any tenant has
already been  received by such tenant,  except as set forth on Schedule I. There
has been no prior sale,  transfer or assignment,  hypothecation or pledge of any
Lease or of the Rents  received  therein.  Except as set  forth on  Schedule  I,
Borrower has not  consented to any  assignment by any tenant of its Lease or any
sublease of all or any portion of the premises demised  thereby,  no such tenant
holds its leased premises under  assignment or sublease,  nor does anyone except
such tenant and its employees occupy such leased  premises.  No tenant under any
Lease has a right or option  pursuant to such Lease or otherwise to purchase all
or any part of the leased  premises or the building of which the leased premises
are a part.  No tenant  under any Lease has any right or option  for  additional
space in the  Improvements  except  as set  forth in the  Lease.  To the best of
Borrower's  knowledge,  no hazardous wastes or toxic  substances,  as defined by
applicable federal,  state or local statutes,  rules and regulations,  have been
disposed, stored or treated by any tenant under any Lease on or about the leased
premises in violation of  applicable  environmental  laws nor does Borrower have
any  knowledge  of any  tenant's  intention  to use its leased  premises for any

activity which, directly or indirectly, involves the use, generation, treatment,
storage,  disposal or  transportation  of any petroleum  product or any toxic or
hazardous  chemical,  material,  substance or waste in  violation of  applicable
Environmental Laws.

therein).

name and from its own office, shall not identify itself or any of its Affiliates
as a division  or part of the other and shall  maintain  and  utilize a separate
telephone  number and separate  stationery,  invoices and checks;  provided that

its contemplated business operations.

asset is its interest in Borrower  and such SPC Party will at all times  comply,
and will cause Borrower to comply, with each of the representations, warranties,
and  covenants  contained  in this  Section  4.1.30  as if such  representation,
warranty or covenant was made directly by such SPC Party. Upon the withdrawal or

its Affiliates  (except as an independent  director on the board of directors of
Finance and certain other  corporations,  each a single purpose  entity);  (iii)
Finance,  the Partnership or any of their  Affiliates  (except as an independent
director on the board of  directors of Finance and certain  other  corporations,
each a single  purpose  entity  (collectively,  the  "Prime  Entities");  (iv) a

controlled  by, or under  common  control  with any such  stockholder,  partner,
customer,  supplier or other Person; or (vi) a member of the immediate family of
any Person  described in clauses (i), (ii) or (iii).  (As used herein,  the term
"control" means the possession,  directly or indirectly,  of the power to direct
or cause the  direction  of  management,  policies  or  activities  of a Person,
whether through ownership of voting securities, by contract or otherwise.)

     (q)  Borrower  shall not cause or permit the board of  directors  of an SPC
Party  to  take  any  action  which,  under  the  terms  of any  certificate  of
incorporation,  by-laws or any voting trust agreement with respect to any common
stock,  requires  the vote of any SPC Party  unless  at the time of such  action
there shall be at least one member who is an Independent Director.

     (r) Borrower  shall allocate  fairly and  reasonably any overhead  expenses

from its own funds.

     (u) Borrower shall conduct its business so that the  assumptions  made with
respect to Borrower in the  Insolvency  Opinion shall be true and correct in all
respects.

     4.1.31 MANAGEMENT AGREEMENT.  The Management Agreement is in full force and
effect and, to the best of Borrower's  knowledge there is no default  thereunder
by any party  thereto and no event has occurred  that,  with the passage of time
and/or the giving of notice would constitute a default thereunder.

     4.1.32 GROUND LEASE.  Borrower hereby represents and warrants to Lender the
following with respect to the Ground Lease:

     (a) Recording; Modification. A memorandum of the Ground Lease has been duly
recorded.  The Ground Lease permits the interest of Borrower to be encumbered by
a mortgage or the ground lessor has approved and consented to the encumbrance of
the Property by the Mortgage. There have not been amendments or modifications to
the terms of the Ground  Lease  since its  recordation,  with the  exception  of
written  instruments  which  have been  recorded.  The  Ground  Lease may not be
canceled,  terminated,  surrendered  or amended by  Borrower  without  the prior
written consent of Lender.

     (b) No Liens. Except for the Permitted Encumbrances, Borrower's interest in
the Ground Lease is not subject to any Liens or encumbrances  superior to, or of
equal priority with,  the Mortgage  other than the ground  lessor's  related fee
interest and the existing mortgage on the ground lessor's fee interest.

     (c) Ground  Lease  Assignable.  Borrower's  interest in the Ground Lease is
assignable  to Lender  upon  notice to, but  without  the consent of, the ground
lessor (or, if any such consent is required,  it has been obtained  prior to the
Closing  Date).  The Ground Lease  contains no  restrictions  on  assignment  by
Lender, its successors and assigns.

     (d) Default.  As of the date hereof,  the Ground Lease is in full force and
effect and no default has  occurred  under the Ground  Lease and, to the best of
Borrower's knowledge,  there is no existing condition which, but for the passage
of time or the giving of notice,  could  result in a default  under the terms of
the Ground Lease.
                                      -18-
<PAGE>
     (e) Notice.  The Ground Lease  requires the ground lessor to give notice of
any  default by  Borrower  to Lender.  The Ground  Lease,  or  estoppel  letters
received  by Lender  from the ground  lessor,  further  provides  that notice of
termination  given under the Ground Lease is not effective against Lender unless
a copy of the notice has been delivered to Lender in the manner described in the
Ground Lease.

     (f) Cure. Lender is permitted the opportunity to cure any default under the
Ground Lease, which is curable after the receipt of notice of any of the default
before the ground lessor thereunder may terminate the Ground Lease in accordance
with Article XI of the Ground Lease.

     (g) Term.  The Ground Lease has a term which extends not less than ten (10)
years beyond the Maturity Date.

     (h) New Lease.  The Ground Lease  (together with an estoppel  received from
the ground lessor)  provides,  in accordance  with Article XI thereof,  that the
ground lessor shall enter into a new lease upon  termination of the Ground Lease
for  any  reason,  including  rejection  of the  Ground  Lease  in a  bankruptcy
proceeding.

     (i)  Insurance  Proceeds.  Under  the  terms of the  Ground  Lease  and the
Mortgage,  taken together,  any related insurance and condemnation proceeds will
be applied  either to the repair or  restoration of all or part of the Property,
with  Lender  having  the right to hold and  disburse  the  proceeds  payable to
Borrower  in  accordance  with  Article XI thereof as the repair or  restoration
progresses,  or to the payment of the outstanding  principal balance of the Loan
together with any accrued interest thereon.

     (j)  Subleasing.  Subject to the provisions of Articles XXI and XXXI of the
Ground Lease, Borrower may enter into subleases from time to time for all or any
portion of the property demised thereby.

     4.1.33 ILLEGAL ACTIVITY.  To the best of Borrower's knowledge no portion of
the  Property  has  been or will  be  purchased  with  proceeds  of any  illegal
activity.

     4.1.34  NO  CHANGE IN FACTS OR  CIRCUMSTANCES;  DISCLOSURE.  To the best of
Borrower's knowledge, all information submitted by Borrower to Lender and in all
financial  statements,  rent rolls,  reports,  certificates  and other documents
submitted in connection  with the Loan or in  satisfaction  of the terms thereof
and all  statements  of fact made by Borrower in this  Agreement or in any other
Loan  Document,  are  accurate,  complete and correct in all material  respects.
There has been no material adverse change in any condition,  fact,  circumstance
or event  that  would  make  any  such  information  inaccurate,  incomplete  or
otherwise  misleading in any material  respect or that otherwise  materially and
adversely  affects or might  materially and adversely affect the Property or the
business  operations  or the  financial  condition  of  Borrower.  Borrower  has
disclosed  to Lender  all  material  facts and has not  failed to  disclose  any
material fact that could cause any  representation or warranty made herein to be
materially misleading.

     Section 4.2 SURVIVAL OF REPRESENTATIONS.

     Borrower agrees that all of the  representations and warranties of Borrower
set forth in Section 4.1 and  elsewhere in this  Agreement and in the other Loan
Documents  shall survive for so long as any amount remains owing to Lender under
this   Agreement  or  any  of  the  other  Loan   Documents  by  Borrower.   All
representations,  warranties, covenants and agreements made in this Agreement or
in the other Loan Documents by Borrower shall be deemed to have been relied upon
by Lender  notwithstanding  any  investigation  heretofore or hereafter  made by
Lender or on its behalf.

     V. BORROWER COVENANTS

     Section 5.1 AFFIRMATIVE COVENANTS.

     From the date  hereof  and until  payment  and  performance  in full of all
obligations of Borrower  under the Loan Documents or the earlier  release of the
Lien of the Mortgage (and all related  obligations) in accordance with the terms
of this Agreement and the other Loan Documents,  Borrower  hereby  covenants and
agrees with Lender that:

     5.1.1 EXISTENCE;  COMPLIANCE WITH LEGAL REQUIREMENTs;  INSURANCE.  Borrower
shall do or cause to be done all things necessary to preserve, renew and keep in
full force and effect its existence,  rights,  licenses,  permits and franchises


                                      -19-
<PAGE>
and comply with all Legal Requirements applicable to it and the Property.  There
shall never be  committed  by Borrower or any other  person in  occupancy  of or
involved with the operation or use of the Property any act or omission affording
the federal  government or any state or local government the right of forfeiture
as against the Property or any part thereof or any monies paid in performance of
Borrower's  obligations  under  any  of  the  Loan  Documents.  Borrower  hereby
covenants  and  agrees  not to  commit,  permit  or  suffer  to exist any act or
omission  affording  such  right of  forfeiture.  Borrower  shall  at all  times
maintain,  preserve and protect all  franchises and trade names and preserve all
the  remainder of its property used or useful in the conduct of its business and
shall keep the Property in good working order and repair,  and from time to time
make,  or  cause  to  be  made,  all  reasonably  necessary  repairs,  renewals,
replacements,  betterments and improvements  thereto, all as more fully provided
in the  Mortgage.  Borrower  shall  keep the  Property  insured  at all times by
financially sound and reputable insurers, to such extent and against such risks,
and maintain  liability and such other  insurance,  as is more fully provided in
this Agreement.

     5.1.2  TAXES  AND  OTHER  CHARGES.  Borrower  shall pay all Taxes and Other
Charges now or hereafter  levied or assessed or imposed  against the Property or
any  part  thereof  as the  same  become  due and  payable;  provided,  however,
Borrower's  obligation  to directly pay Taxes shall be suspended  for so long as
Borrower complies with the terms and provisions of Section 7.2 hereof.  Borrower
will deliver to Lender  receipts for payment or other evidence  satisfactory  to
Lender  that the  Taxes  and  Other  Charges  have  been so paid or are not then
delinquent  no later  than ten (10)  days  prior to the date on which  the Taxes
and/or Other Charges would  otherwise be delinquent if not paid.  Borrower shall
furnish to Lender  receipts  for the payment of the Taxes and the Other  Charges
prior to the date the same shall  become  delinquent  (provided,  however,  that
Borrower is not  required to furnish  such  receipts for payment of Taxes in the
event that such Taxes have been paid by Lender  pursuant to Section 7.2 hereof).
Borrower shall not suffer and shall promptly cause to be paid and discharged any
Lien or charge  whatsoever  which may be or become a Lien or charge  against the
Property,  and shall  promptly  pay for all  utility  services  provided  to the
Property.  After prior written notice to Lender,  Borrower,  at its own expense,
may contest by appropriate legal proceeding, promptly initiated and conducted in
good faith and with due  diligence,  the amount or  validity or  application  in
whole or in part of any  Taxes,  Liens or Other  Charges,  provided  that (i) no
Event of Default has occurred and remains uncured; (ii) Borrower is permitted to
do so under the  provisions of any mortgage or deed of trust superior in lien to
the Mortgage; (iii) such proceeding shall be permitted under and be conducted in
accordance  with the  provisions of any other  instrument  to which  Borrower is
subject and shall not constitute a default  thereunder and such proceeding shall
be conducted in accordance  with all applicable  statutes,  laws and ordinances;
(iv) neither the  Property  nor any part thereof or interest  therein will be in
danger of being sold,  forfeited,  terminated,  canceled or lost;  (v)  Borrower
shall  promptly  upon  final  determination  thereof  pay the amount of any such
Taxes, Liens, or Other Charges,  together with all costs, interest and penalties
which may be payable in connection therewith; (vi) such proceeding shall suspend
the collection of such contested  Taxes or Other Charges from the Property;  and
(vii) Borrower shall furnish such security as may be required in the proceeding,
or as may be  requested  by Lender,  to insure the  payment of any such Taxes or
Other Charges,  together with all interest and penalties thereon. Lender may pay
over any such cash  deposit  or part  thereof  held by  Lender  to the  claimant
entitled thereto at any time when, in the judgment of Lender, the entitlement of
such claimant is established.

     5.1.3  LITIGATION.  Borrower  shall give prompt written notice to Lender of
any  litigation  or  governmental  proceedings  pending  or  threatened  against
Borrower which might materially adversely affect Borrower's condition (financial
or otherwise) or business or the Property.

     5.1.4 ACCESS TO PROPERTY. Borrower shall permit agents, representatives and
employees of Lender to inspect the  Property or any part  thereof at  reasonable
hours upon reasonable advance notice.

     5.1.5  NOTICE OF DEFAULT.  Borrower  shall  promptly  advise  Lender of any
material adverse change in Borrower's condition,  financial or otherwise,  or of
the occurrence of any Event of Default of which Borrower has knowledge.

     5.1.6 COOPERATE IN LEGAL  PROCEEDINGS.  Borrower shall cooperate fully with
Lender  with  respect  to any  proceedings  before  any  court,  board  or other
Governmental  Authority  which  may in any  way  affect  the  rights  of  Lender
hereunder or any rights obtained by Lender under any of the other Loan Documents
and, in connection therewith,  permit Lender, at its election, to participate in
any such proceedings.

     5.1.7 PERFORM LOAN  DOCUMENTS.  Subject to the limitations on liability set
forth in Section 9.4 hereof, Borrower shall observe, perform and satisfy all the
terms,  provisions,  covenants  and  conditions  of,  and shall pay when due all
costs,  fees and  expenses  to the  extent  required  under  the Loan  Documents
executed and delivered by, or applicable to, Borrower.

     5.1.8 INSURANCE BENEFITS. Borrower shall cooperate with Lender in obtaining
for Lender the benefits of any Insurance  Proceeds lawfully or equitably payable
in  connection  with  the  Property,  and  Lender  shall be  reimbursed  for any
reasonable  expenses  incurred in  connection  therewith  (including  reasonable
attorneys' fees and disbursements, and the payment by Borrower of the expense of
an appraisal on behalf of Lender in case of a fire or other  casualty  affecting
the Property or any part thereof) out of such Insurance Proceeds.

     5.1.9 FURTHER  ASSURANCES.  Borrower  shall,  at  Borrower's  sole cost and
expense:

     (a)   execute  and   deliver  to  Lender   such   documents,   instruments,
certificates,  assignments and other writings,  and do such other acts necessary
or desirable,  to evidence,  preserve  and/or protect the collateral at any time
securing  or  intended  to secure the  obligations  of  Borrower  under the Loan
Documents, as Lender may reasonably require; and

     (b) do and  execute  all and  such  further  lawful  and  reasonable  acts,
conveyances and assurances for the better and more effective carrying out of the
intents and purposes of this Agreement and the other Loan  Documents,  as Lender
shall reasonably require from time to time.

     5.1.10 MORTGAGE TAXES. As of the date hereof,  Borrower  represents that it
has paid all state,  county and municipal  recording and all other taxes imposed
upon the execution and recordation of the Mortgage.

     5.1.11 FINANCIAL REPORTING.

     (a) Borrower will keep and maintain or will cause to be kept and maintained
on a Fiscal Year basis, in accordance with GAAP (or such other  accounting basis
acceptable  to  Lender),   proper  and  accurate  books,  records  and  accounts
reflecting all of the financial  affairs of Borrower and all items of income and
expense in connection with the operation of the Property.  Lender shall have the
right  from  time  to  time at all  times  during  normal  business  hours  upon
reasonable  notice to examine such books,  records and accounts at the office of
Borrower or other  Person  maintaining  such books,  records and accounts and to
make  such  copies  or  extracts  thereof  as  Lender  shall  desire.  After the
occurrence  of an Event of Default,  Borrower  shall pay any costs and  expenses
incurred by Lender to examine Borrower's  accounting records with respect to the
Property,  as Lender  shall  determine to be  necessary  or  appropriate  in the
protection of Lender's interest.

     (b)  Borrower  will  furnish to Lender  annually  within  ninety  (90) days
following the end of each Fiscal Year of Borrower, a complete copy of Borrower's
annual  financial  statements  audited by a "Big Five"  accounting firm or other
independent  certified public accountant  acceptable to Lender (Ernst & Young is
hereby  approved)  in  accordance  with  GAAP (or such  other  accounting  basis
acceptable to Lender)  covering the Property for such Fiscal Year and containing
statements  of operations  for Borrower and a balance  sheet for Borrower.  Such
statements shall set forth the financial condition and the results of operations
for the Property for such Fiscal Year.  Borrower's  annual financial  statements
shall be accompanied by (i) a comparison of the budgeted income and expenses and
the actual  income and expenses for the prior  Fiscal Year,  (ii) a  certificate
executed by the chief financial officer of Borrower or the general partner of or
the general partner of the general partner of Borrower,  as applicable,  stating
that  each  such  annual  financial  statement  presents  fairly  the  financial
condition  and the results of  operations  of Borrower  and the  Property  being
reported  upon  and has been  prepared  in  accordance  with  GAAP and  (iii) an
unqualified  opinion on Borrower's  annual financial  statements of a "Big Five"

a commercially  reasonable manner to preserve and protect the Property provided,
however,  that no such  termination or surrender of any Lease covering more than

(iii)  shall not  collect  any of the rents  more than one (1) month in  advance
(other than security  deposits);  (iv) shall not execute any other assignment of

the Net Operating Income.  Notwithstanding the foregoing, Lender's consent shall
not be required in connection with any alterations that will not have a material
adverse effect on Borrower's financial  condition,  the value of the Property or

with (a) tenant  improvement  work performed  pursuant to the terms of any Lease
executed on or before the date hereof,  (b) tenant  improvement  work  performed

the Property after the occurrence of a casualty in accordance with the terms and
provisions of this  Agreement.  If the total unpaid amounts due and payable with





                                      -23-
<PAGE>
respect to  alterations  to the  Improvements  at the Property  (other than such
amounts to be paid or  reimbursed by tenants under the Leases) shall at any time
exceed Seven Million Two Hundred Thousand and 00/100 Dollars  ($7,200,000)  (the
"Threshold  Amount"),  Borrower shall promptly deliver to Lender as security for
the  payment  of  such  amounts  and  as  additional   security  for  Borrower's
obligations  under the Loan Documents any of the  following:  (A) cash, (B) U.S.
Obligations,  (C) other securities having a rating acceptable to Lender and that
the  applicable  Rating  Agencies have  confirmed in writing will not, in and of
itself,  result in a downgrade,  withdrawal or qualification of the initial, or,
if higher,  then current ratings assigned in connection with any Securitization,
or (D) a completion  bond or letter of credit issued by a financial  institution
having a rating by Standard & Poor's  Ratings Group of not less than A-1+ if the
term of such bond or letter of credit is no longer  than three (3) months or, if
such term is in excess of three (3) months,  issued by a  financial  institution
having a rating  that is  acceptable  to Lender and that the  applicable  Rating
Agencies  have  confirmed  in writing  will not,  in and of itself,  result in a
downgrade,  withdrawal  or  qualification  of the initial,  or, if higher,  then
current ratings  assigned in connection with any  Securitization.  Such security
shall be in an  amount  equal to the  excess of the total  unpaid  amounts  with
respect to  alterations  to the  Improvements  on the Property  (other than such
amounts to be paid or reimbursed by tenants under the Leases) over the Threshold
Amount  and  applied  from time to time at the  option of Lender to Pay for such
alterations or to terminate any of the  alterations  and restore the Property to
the extent  necessary to prevent any material adverse effect on the value of the
Property.

exemption) prohibited transaction under ERISA.

period. All proceeds payable to Lender pursuant to this subsection shall be held
by Lender and shall be applied to the obligations  secured by the Loan Documents
from time to time due and  payable  hereunder  and  under  the  Note;  provided,
however,  that nothing herein  contained shall be deemed to relieve  Borrower of

insurance  and in such  reasonable  amounts  as  Lender  from  time to time  may
reasonably  request against such other  insurable  hazards which at the time are

around the region in which the Property is located.

     (b) All insurance  provided for in Section  6.1(a) shall be obtained  under
valid and enforceable policies (collectively, the "Policies" or in the singular,
the "Policy") and shall be subject to approval of lender as to deductibles.  The

Property the amount of coverage from time to time  required  hereunder and shall
otherwise  provide the same  protection as would a separate Policy insuring only
the Property in compliance with the provisions of Section 6.1(a).
 
     (d) All  Policies of  insurance  provided  for or  contemplated  by Section
6.1(a),  except  for the Policy  referenced  in  Section  6.1(a)(v),  shall name
Borrower,  as the insured and Lender as the additional insured, as its interests
may appear, and in the case of property damage, boiler and machinery,  flood and
earthquake insurance, shall contain a standard non-contributing mortgagee clause
in favor of  Lender  providing  that the loss  thereunder  shall be  payable  to
Lender.

     (e) All  Policies of  insurance  provided  for in Section  6.1(a)(v)  shall
contain clauses or endorsements to the effect that:

          (i) no act or negligence  of Borrower,  or anyone acting for Borrower,
or of any Tenant or other occupant,  or failure to comply with the provisions of
any Policy, which might otherwise result in a forfeiture of the insurance or any
part  thereof,  shall in any way affect the  validity or  enforceability  of the
insurance insofar as Lender is concerned;

          (ii)  the  Policy  shall  not be  materially  changed  (other  than to
increase the coverage provided thereby) or canceled without at least thirty (30)
days'  written  notice  to  Lender  and any  other  party  named  therein  as an
additional insured;

          (iii) the issuers  thereof shall give written  notice to Lender if the
Policy has not been renewed fifteen (15) days prior to its expiration; and

          (iv) Lender shall not be liable for any Insurance  Premiums thereon or
subject to any assessments thereunder.



                                      -27-

     (f) If at any time  Lender is not in receipt of written  evidence  that all
insurance required hereunder is in full force and effect,  Lender shall have the
right, without notice to Borrower, to take such action as Lender deems necessary
to protect its interest in the  Property,  including,  without  limitation,  the
obtaining  of such  insurance  coverage as Lender in its sole  discretion  deems
appropriate.  All premiums  incurred by Lender in connection with such action or
in obtaining  such  insurance and keeping it in effect shall be paid by Borrower
to Lender upon demand and,  until  paid,  shall be secured by the  Mortgage  and
shall bear interest at the Default Rate.

     Section 6.2 CASUALTY.  If the Property  shall be damaged or  destroyed,  in
whole or in part, by fire or other casualty (a "Casualty"),  Borrower shall give
prompt  notice of such damage to Lender and,  provided that the Net Proceeds are
made available for restoration, shall promptly commence and diligently prosecute
the  completion  of the  repair and  restoration  of the  Property  as nearly as
possible to the condition the Property was in immediately  prior to such fire or
other casualty, with such alterations as may be reasonably approved by Lender (a
"Restoration")  and otherwise in accordance with Section 6.4. Borrower shall pay
all  costs  of such  Restoration  whether  or not  such  costs  are  covered  by
insurance.  Lender may,  but shall not be obligated to make proof of loss if not
made  promptly  by  Borrower.  If Lender  should  elect to apply  the  insurance
proceeds  it  receives  to the  payment of the Debt  without  first  making such
insurance  proceeds  available for the full  restoration  of the Property,  then
notwithstanding  anything to the contrary  contained  herein,  Borrower shall be
excused  from any  obligation  to  restore  the  Property  following  an insured
casualty and such failure to restore shall not  constitute a default or an Event
of Default.

     Section 6.3 CONDEMNATION. Borrower shall promptly give Lender notice of the
actual or threatened  commencement of any proceeding for the Condemnation of the
Property  and shall  deliver to Lender  copies of any and all  papers  served in
connection   with  such   proceedings.   Lender  may  participate  in  any  such
proceedings,  and  Borrower  shall  from  time to time  deliver  to  Lender  all
instruments  reasonably  requested by it to permit such participation.  Borrower
shall,  at its expense,  diligently  prosecute any such  proceedings,  and shall
consult with Lender,  its attorneys and experts,  and cooperate with them in the
carrying on or defense of any such  proceedings.  Notwithstanding  any taking by
any  public  or  quasi-public   authority  through   Condemnation  or  otherwise
(including but not limited to any transfer made in lieu of or in anticipation of
the exercise of such  taking),  Borrower  shall  continue to pay the Debt at the
time  and in the  manner  provided  for  its  payment  in the  Note  and in this
Agreement  and the Debt  shall not be  reduced  until any Award  shall have been
actually  received  and applied by Lender,  after the  deduction  of expenses of
collection,  to the  reduction  or  discharge  of the Debt.  Lender shall not be
limited to the interest paid on the Award by the condemning  authority but shall
be entitled to receive out of the Award  interest at the rate or rates  provided
herein or in the Note.  If the  Property  or any  portion  thereof is taken by a
condemning  authority,  Borrower  shall,  provided  the Net  Proceeds  are  made
available  for  Restoration,  promptly  commence and  diligently  prosecute  the
Restoration of the Property and otherwise  comply with the provisions of Section
6.4. If the Property is sold,  through  foreclosure  or otherwise,  prior to the
receipt by Lender of the Award,  Lender  shall have the right,  whether or not a
deficiency judgment on the Note shall have been sought,  recovered or denied, to
receive the Award, or a portion thereof sufficient to pay the Debt.

     Section 6.4 RESTORATION. The following provisions shall apply in connection
with the Restoration of the Property:

     (a) If the Net  Proceeds  shall  be less  than  Two  Million  Five  Hundred
Thousand  and  No/100  Dollars  ($2,500,000)  and the  costs of  completing  the
Restoration  shall be less than Two Million  Five  Hundred  Thousand  and No/100
Dollars  ($2,500,000),  the Net Proceeds will be disbursed by Lender to Borrower
upon receipt, provided that all of the conditions set forth in Section 6.4(b)(i)
are met and Borrower  delivers to Lender a written  undertaking to expeditiously
commence and to  satisfactorily  complete with due diligence the  Restoration in
accordance with the terms of this Agreement.

     (b) If the Net  Proceeds  are equal to or  greater  than Two  Million  Five
Hundred Thousand and No/100 Dollars  ($2,500,000) or the costs of completing the
Restoration is equal to or greater than Five Hundred Thousand and No/100 Dollars
($500,000)  Lender shall make the Net Proceeds  available for the Restoration in
accordance  with the provisions of this Section 6.4. The term "Net Proceeds" for
purposes of this  Section 6.4 shall  mean:  (i) the net amount of all  insurance
proceeds received by Lender pursuant to Section 6.1 (a)(i),  (iv), (vi) and (ix)
as a result of such damage or  destruction,  after  deduction of its  reasonable
costs and expenses (including,  but not limited to, reasonable counsel fees), if


                                      -28-
<PAGE>
any, in collecting same  ("Insurance  Proceeds"),  or (ii) the net amount of the
Award, after deduction of its reasonable costs and expenses (including,  but not
limited to, reasonable counsel fees), if any, in collecting same  ("Condemnation
Proceeds"), whichever the case may be.

          (i)  The  Net  Proceeds  shall  be  made  available  to  Borrower  for
     Restoration provided that each of the following conditions are met:

               (A) no Event of Default shall have occurred and be continuing;

               (B) (1) in the event the Net  Proceeds  are  Insurance  Proceeds,
          less than  twenty-five  percent  (25%) of the total  floor area of the
          Improvements  on the Property has been damaged,  destroyed or rendered
          unusable  as a result  of such  fire or other  casualty  or (2) in the
          event  the Net  Proceeds  are  Condemnation  Proceeds,  less  than ten
          percent (10%) of the land constituting the Property is taken, and such
          land is located along the perimeter or periphery of the Property,  and
          no material portion of the Improvements is located on such land;

                    (C) Leases  demising in the  aggregate a  percentage  amount
               equal to or greater than the  Rentable  Space  Percentage  of the
               total rentable space in the Property which has been demised under
               executed  and  delivered  Leases  in effect as of the date of the
               occurrence  of such fire or other  casualty or taking,  whichever
               the case may be, shall remain in full force and effect during and
               after the completion of the Restoration. The term "Rentable Space
               Percentage"  shall mean a percentage amount equal to seventy-five
               percent (75%);

                    (D)  Borrower  shall  commence  the  Restoration  as soon as
               reasonably  practicable  (but in no event  later  than sixty (60)
               days after such damage or  destruction  or taking,  whichever the
               case may be,  occurs)  and shall  diligently  pursue  the same to
               satisfactory completion;

                    (E) Lender shall be satisfied  that any operating  deficits,
               including all scheduled  payments of principal and interest under
               the Note,  which will be incurred with respect to the Property as
               a result of the  occurrence of any such fire or other casualty or
               taking, whichever the case may be, will be covered out of (1) the
               Net Proceeds,  (2) the insurance  coverage referred to in Section
               6.1(a)(iii), if applicable, or (3) by other funds of Borrower;

                    (F) Lender shall be satisfied that the  Restoration  will be
               completed  on or before the earliest to occur of (1) the Maturity
               Date,  (2) the earliest date required for such  completion  under
               the terms of any Major  Leases,  (3) such time as may be required
               under  applicable  zoning law,  ordinance,  rule or regulation in
               order to repair and restore the Property to the  condition it was
               in  immediately  prior to such  fire or other  casualty  or to as
               nearly as possible the condition it was in  immediately  prior to
               such taking, as applicable or (4) the expiration of the insurance
               coverage referred to in Section 6.1(a)(iii);

                    (G) the Property and the use thereof  after the  Restoration
               will be in  compliance  with and permitted  under all  applicable
               zoning laws, ordinances, rules and regulations;

                    (H) the Restoration  shall be done and completed by Borrower
               in a  diligent  fashion  and in  compliance  with all  applicable
               governmental  laws,  rules and  regulations  (including,  without
               limitation, all applicable environmental laws); and

                    (I) such fire or other  casualty or taking,  as  applicable,
               does not  result  in the loss of access  to the  Property  or the
               related Improvements; and

                    (J) the Casualty  Consultant  shall have determined that the
               Net Proceeds are sufficient to fully pay for the Restoration.

          (ii) The Net Proceeds  shall be held by Lender in an  interest-bearing
     account and,  until  disbursed in  accordance  with the  provisions of this
     Section 6.4(b), shall constitute additional security for the Debt and other
     obligations  under the Loan Documents.  The Net Proceeds shall be disbursed
     by Lender to, or as  directed  by,  Borrower  from time to time  during the
     course of the Restoration,  upon receipt of evidence satisfactory to Lender


                                      -29-
<PAGE>
     that (A) all materials  installed and work and labor  performed  (except to
     the extent that they are to be paid for out of the requested  disbursement)
     in  connection  with the  Restoration  have been paid for in full,  and (B)
     there  exist  no  notices  of   pendency,   stop  orders,   mechanic's   or
     materialman's  liens or notices  of  intention  to file same,  or any other
     liens or encumbrances  of any nature  whatsoever on the Property which have
     not either been fully bonded to the  satisfaction  of Lender and discharged
     of record or in the alternative fully insured to the satisfaction of Lender
     by the title company issuing the Title Insurance Policy.

          (iii) All plans and  specifications  required in  connection  with the
     Restoration shall be subject to prior review and acceptance in all respects
     by Lender and by an independent consulting engineer selected by Lender (the
     "Casualty  Consultant").  Lender  shall  have  the  use  of the  plans  and
     specifications and all permits, licenses and approvals required or obtained
     in  connection  with the  Restoration.  The  identity  of the  contractors,
     subcontractors and materialmen  engaged in the Restoration,  as well as the
     contracts  under  which they have been  engaged,  shall be subject to prior
     review and acceptance by Lender and the Casualty Consultant. All reasonable
     costs and  expenses  incurred by Lender in  connection  with making the Net
     Proceeds  available  for the  Restoration  including,  without  limitation,
     reasonable  counsel fees and  disbursements  and the Casualty  Consultant's
     fees, shall be paid by Borrower.

          (iv) In no event shall Lender be obligated  to make  disbursements  of
     the Net  Proceeds  in  excess  of an  amount  equal to the  costs  actually
     incurred from time to time for work in place as part of the Restoration, as
     certified by the Casualty  Consultant,  minus the Casualty  Retainage.  The
     term "Casualty  Retainage"  shall mean an amount equal to ten percent (10%)
     (with release of retainage for subcontract  where work is completed) of the
     costs actually  incurred for work in place as part of the  Restoration,  as
     certified  by the  Casualty  Consultant,  until  the  Restoration  has been
     completed.  The Casualty  Retainage shall in no event, and  notwithstanding
     anything to the contrary set forth above in this  Section  6.4(b),  be less
     than  the  amount   actually  held  back  by  Borrower  from   contractors,
     subcontractors  and materialmen  engaged in the  Restoration.  The Casualty
     Retainage shall not be released until the Casualty Consultant  certifies to
     Lender that the  Restoration  has been  completed  in  accordance  with the
     provisions of this Section 6.4(b) and that all approvals  necessary for the
     re-occupancy   and  use  of  the  Property  have  been  obtained  from  all
     appropriate  governmental and  quasi-governmental  authorities,  and Lender
     receives evidence  satisfactory to Lender that the costs of the Restoration
     have  been  paid in full  or  will  be  paid  in full  out of the  Casualty
     Retainage;  provided,  however, that Lender will release the portion of the
     Casualty Retainage being held with respect to any contractor, subcontractor
     or  materialman  engaged in the  Restoration  as of the date upon which the
     Casualty Consultant certifies to Lender that the contractor,  subcontractor
     or materialman has  satisfactorily  completed all work and has supplied all
     materials  in  accordance   with  the   provisions  of  the   contractor's,
     subcontractor's or materialman's contract, the contractor, subcontractor or
     materialman  delivers  the lien  waivers and evidence of payment in full of
     all sums due to the  contractor,  subcontractor  or  materialman  as may be
     reasonably  requested by Lender or by the title  company  issuing the Title
     Insurance Policy, and Lender receives an endorsement to the Title Insurance
     Policy  insuring  the  continued  priority of the lien of the  Mortgage and
     evidence  of  payment  of any  premium  payable  for such  endorsement.  If
     required  by  Lender,  the  release  of any such  portion  of the  Casualty
     Retainage shall be approved by the surety company, if any, which has issued
     a payment or performance bond with respect to the contractor, subcontractor
     or materialman.

          (v) Lender  shall not be obligated  to make  disbursements  of the Net
     Proceeds more frequently than once every calendar month.

          (vi)  If at any  time  the Net  Proceeds  or the  undisbursed  balance
     thereof  shall  not,  in the  opinion  of Lender in  consultation  with the
     Casualty Consultant,  be sufficient to pay in full the balance of the costs
     which are estimated by the Casualty Consultant to be incurred in connection
     with the completion of the Restoration,  no further  disbursements shall be
     made until such time as such deficiency shall no longer exist.

          (vii) The excess,  if any, of the Net Proceeds  deposited  with Lender
     after the Casualty Consultant  certifies to Lender that the Restoration has
     been completed in accordance  with the  provisions of this Section  6.4(b),
     and the receipt by Lender of evidence satisfactory to Lender that all costs



                                      -30-
<PAGE>
     incurred in connection with the Restoration  have been paid in full,  shall
     be remitted by Lender to Borrower,  provided no Event of Default shall have
     occurred and shall be continuing  under the Note,  this Agreement or any of
     the other Loan Documents.

     (c)  All  Net  Proceeds  not  required  (i) to be  made  available  for the
Restoration  or (ii) to be returned to Borrower as excess Net Proceeds  pursuant
to Section  6.4(b)(vii) may be retained and applied by Lender toward the payment
of the Debt  whether or not then due and  payable in such  order,  priority  and
proportions  as Lender in its sole  discretion  shall  deem  proper,  or, at the
discretion  of  Lender,  the same may be paid,  either  in whole or in part,  to
Borrower for such purposes as Lender shall designate, in its discretion.

     (d) In the  event  of  foreclosure  of the  Mortgage  with  respect  to the
Property,  or other transfer of title to the Property in extinguishment in whole
or in part of the Debt all right,  title and  interest of Borrower in and to the
Policies that are not blanket Policies then in force concerning the Property and
all proceeds  payable  thereunder  shall thereupon vest in the purchaser at such
foreclosure or Lender or other transferee in the event of such other transfer of
title.

     VII. RESERVE FUNDS

     Section 7.1 INTENTIONALLY OMITTED.

     Section 7.2 TAX ESCROW FUND.

     On each Payment Date,  Borrower shall deposit with Agent in accordance with
the Cash Management Agreement (a) one-twelfth of the Taxes that Lender estimates
will be  payable  during  the  next  ensuing  twelve  (12)  months  in  order to
accumulate  with Lender  sufficient  funds to pay all such Taxes at least thirty
(30) days prior to their  respective due dates (said amounts in (a)  hereinafter
called the "Tax Escrow Fund"). Lender will apply the Tax Escrow Fund to payments
of Taxes  required to be made by Borrower  pursuant to Section  5.1.2 hereof and
under the  Mortgage.  In making any  payment  relating  to the Tax Escrow  Fund,
Lender may do so according to any bill,  statement or estimate procured from the
appropriate  public  office (with  respect to Taxes),  without  inquiry into the
accuracy of such bill,  statement  or estimate or into the  validity of any tax,
assessment,  sale, forfeiture, tax lien or title or claim thereof. If the amount
of the Tax  Escrow  Fund shall  exceed the  amounts  due for Taxes  pursuant  to
Section 5.1.2 hereof, Lender shall, in its sole discretion, return any excess to
Borrower  or credit such excess  against  future  payments to be made to the Tax
Escrow Fund. Any amount remaining in the Tax Escrow Fund after the Debt has been
paid in full shall be returned to Borrower.  In allocating  such excess,  Lender
may deal with the Person  shown on the  records of Lender to be the Owner of the
Property.  If at any time Lender reasonably  determines that the Tax Escrow Fund
is not or will not be  sufficient  to pay Taxes and  Insurance  Premiums  by the
dates set forth in (a) and (b)  above,  Lender  shall  notify  Borrower  of such
determination  and Borrower shall increase its monthly payments to Lender by the
amount that Lender  estimates is sufficient  to make up the  deficiency at least
thirty (30) days prior to delinquency of the Taxes and/or thirty (30) days prior
to expiration of the Policies, as the case may be.

     Section 7.3 INTENTIONALLY DELETED.

     Section 7.4 TERMINATION ACCOUNT.

     In the event that any termination  payments are paid pursuant to Section 35
of the Everen Lease, all such amounts shall be delivered to Lender and deposited
into a segregated  account with Agent (the "Termination  Account").  All amounts
deposited  into the  Termination  Account shall be invested in  accordance  with
Section 35 of the Lease and shall constitute  additional security for payment of
the Debt;  provided,  however,  that if an Event of Default shall occur,  Lender
shall not apply such amounts to the payment of the Debt until the  occurrence of
the Early Termination Date (as defined in the Everen Lease).

     Section 7.5 RESERVE FUNDS, GENERALLY.

     7.5.1  Borrower  grants  to  Lender  a  first-priority  perfected  security
interest  in each of the Reserve  Funds and any and all monies now or  hereafter
deposited in each Reserve Fund as  additional  security for payment of the Debt.
Until  expended  or applied in  accordance  herewith,  the  Reserve  Funds shall
constitute additional security for the Debt.





                                      -31-
<PAGE>
     7.5.2 Upon the  occurrence of an Event of Default,  Lender may, in addition
to any and all other  rights and remedies  available  to Lender,  apply any sums
then  present in any or all of the  Reserve  Funds to the payment of the Debt in
any order in its sole discretion.

     7.5.3 Borrower shall not,  without  obtaining the prior written  consent of
Lender,  further  pledge,  assign or grant any security  interest in any Reserve
Fund or the monies deposited therein or permit any lien or encumbrance to attach
thereto,  or any levy to be made  thereon,  or any UCC-1  Financing  Statements,
except  those  naming  Lender as the  secured  party,  to be filed with  respect
thereto.

     7.5.4 Lender shall not be liable for any loss  sustained on the  investment
of any funds constituting the Reserve Funds.

     VIII. DEFAULTS

     Section 8.1 EVENT OF DEFAULT.

     (a) Each of the  following  events  shall  constitute  an event of  default
hereunder (an "Event of Default"):

          (i) if any portion of the Debt is not paid when due;

          (ii) if any of the Taxes or Other  Charges  are not paid when the same
are due and payable  unless  sufficient  escrows are  deposited  for the payment
thereof in accordance with the provisions of Article VII and the Cash Management
Agreement;

          (iii) if the  Policies  are not kept in full force and  effect,  or if
certified  copies of the  Policies are not  delivered to Lender  within ten (10)
days after request;

          (iv) if Borrower  transfers or  encumbers  any portion of the Property
without  Lender's prior written consent or otherwise  violates the provisions of
Article 6 of the Mortgage;

          (v) if any  representation  or warranty made by Borrower  herein or in
any other Loan Document, or in any report,  certificate,  financial statement or
other  instrument,  agreement  or document  furnished  to Lender shall have been
false or misleading in any material respect as of the date the representation or
warranty was made;

          (vi)  if  Borrower  shall  make  an  assignment  for  the  benefit  of
creditors;

          (vii) if a receiver,  liquidator  or trustee  shall be  appointed  for
Borrower  shall be  adjudicated a bankrupt or insolvent,  or if any petition for
bankruptcy, reorganization or arrangement pursuant to federal bankruptcy law, or
any similar federal or state law, shall be filed by or against, consented to, or
acquiesced  in by,  Borrower or such  guarantor,  or if any  proceeding  for the
dissolution or  liquidation  of Borrower or such guarantor  shall be instituted;
provided, however, if such appointment, adjudication, petition or proceeding was
involuntary  and not consented to by Borrower or such  guarantor,  upon the same
not being discharged, stayed or dismissed within sixty (60) days;

contravention of the Loan Documents;

          (ix) if Borrower  breaches any of its  respective  negative  covenants

          (x) with respect to any term,  covenant or provision  set forth herein
which  specifically  contains a notice  requirement or grace period, if Borrower
shall be in default under such term,  covenant or condition  after the giving of
such notice or the expiration of such grace period;

          (xi) if  Borrower  shall  continue  to be in Default  under any of the
other  terms,  covenants  or  conditions  of this  Agreement  not  specified  in

Lender, in the case of any Default which can be cured by the payment of a sum of
money, or for thirty (30) days after notice from Lender in the case of any other
Default; provided,  however, that if such non-monetary Default is susceptible of
cure but cannot  reasonably  be cured  within  such 30-day  period and  provided
further that  Borrower  shall have  commenced  to cure such Default  within such


                                      -32-
<PAGE>
30-day period and thereafter  diligently and expeditiously  proceeds to cure the
same,  such  30-day  period  shall be  extended  for such time as is  reasonably
necessary  for Borrower in the exercise of due  diligence to cure such  Default,
such additional period not to exceed sixty (60) days; or

          (xii) if there shall be default under any of the other Loan  Documents
beyond any applicable cure periods  contained in such  documents,  whether as to
Borrower or the  Property,  or if any other such event shall occur or  condition
shall  exist,  if the effect of such event or  condition  is to  accelerate  the
maturity  of any  portion  of the Debt or to  permit  Lender to  accelerate  the
maturity of all or any portion of the Debt.

     (b) Upon the  occurrence  of an Event of  Default  (other  than an Event of
Default  described  in  clauses  (vi),  (vii) or (viii)  above)  and at any time
thereafter Lender may, in addition to any other rights or remedies  available to
it  pursuant  to this  Agreement  and the other Loan  Documents  or at law or in
equity, Lender may take such action, without notice or demand, that Lender deems
advisable  to  protect  and  enforce  its  rights  against  Borrower  and in the
Property,  including,  without limitation,  declaring the Debt to be immediately
due and payable,  and Lender may enforce or avail itself of any or all rights or
remedies  provided in the Loan  Documents  against  Borrower  and the  Property,
including,  without  limitation,  all rights or remedies  available at law or in
equity; and upon any Event of Default described in clauses (vi), (vii) or (viii)
above,  the Debt and all other  obligations of Borrower  hereunder and under the
other Loan Documents shall immediately and automatically become due and payable,
without notice or demand,  and Borrower hereby  expressly waives any such notice
or  demand,  anything  contained  herein or in any other  Loan  Document  to the
contrary notwithstanding.

     Section 8.2 REMEDIES.

     (a) Upon the  occurrence of an Event of Default,  all or any one or more of
the rights,  powers,  privileges and other remedies  available to Lender against
Borrower under this  Agreement or any of the other Loan  Documents  executed and
delivered by, or applicable to, Borrower or at law or in equity may be exercised
by Lender at any time and from  time to time,  whether  or not all or any of the
Debt shall be declared  due and  payable,  and whether or not Lender  shall have
commenced any foreclosure  proceeding or other action for the enforcement of its
rights  and  remedies  under  any of the  Loan  Documents  with  respect  to the
Property.  Any such actions taken by Lender shall be cumulative  and  concurrent
and may be pursued independently,  singly, successively,  together or otherwise,
at such time and in such order as Lender may  determine in its sole  discretion,
to the fullest extent permitted by law, without impairing or otherwise affecting
the other rights and remedies of Lender  permitted by law, equity or contract or
as set  forth  herein or in the  other  Loan  Documents.  Without  limiting  the
generality  of the  foregoing,  Borrower  agrees  that if an Event of Default is
continuing  (i)  Lender is not  subject  to any "one  action"  or  "election  of
remedies"  law or  rule,  and (ii) all  liens  and  other  rights,  remedies  or
privileges provided to Lender shall remain in full force and effect until Lender
has exhausted all of its remedies against the Property and the Mortgage has been
foreclosed,  sold and/or otherwise  realized upon in satisfaction of the Debt or
the Debt has been paid in full.

     (b) Lender  shall have the right from time to time to  partially  foreclose
the Mortgage in any manner and for any amounts  secured by the Mortgage then due
and payable as determined by Lender in its sole  discretion  including,  without
limitation,  the following  circumstances:  (i) in the event  Borrower  defaults
beyond any  applicable  grace  period in the  payment  of one or more  scheduled
payments of principal and interest, Lender may foreclose the Mortgage to recover
such delinquent payments,  or (ii) in the event Lender elects to accelerate less
than the entire outstanding  principal balance of the Loan, Lender may foreclose
the Mortgage to recover so much of the  principal  balance of the Loan as Lender
may  accelerate and such other sums secured by the Mortgage as Lender may elect.
Notwithstanding  one or more partial  foreclosures,  the  Property  shall remain
subject to the  Mortgage to secure  payment of sums  secured by the Mortgage and
not previously recovered.

     (c) Lender shall have the right from time to time to sever the Note and the
other  Loan  Documents  into one or more  separate  notes,  mortgages  and other
security  documents  (the "Severed Loan  Documents")  in such  denominations  as
Lender shall  determine in its sole  discretion  for purposes of evidencing  and
enforcing its rights and remedies provided hereunder. Borrower shall execute and
deliver to Lender from time to time,  promptly  after the  request of Lender,  a
severance agreement and such other documents as Lender shall request in order to
effect  the  severance  described  in the  preceding  sentence,  all in form and



                                      -33-
<PAGE>
substance reasonably satisfactory to Lender. After the occurrence of an Event of
Default,  Borrower hereby absolutely and irrevocably appoints Lender as its true
and lawful attorney, coupled with an interest, in its name and stead to make and
execute all documents necessary or desirable to effect the aforesaid  severance,
Borrower  ratifying  all that  its said  attorney  shall do by  virtue  thereof;
provided,  however,  Lender shall not make or execute any such  documents  under
such power  until  three (3) days after  notice  has been given to  Borrower  by
Lender of Lender's intent to exercise its rights under such power. Except as may
be required in connection with a securitization  pursuant to Section 9.1 hereof,
(i) Borrower  shall not be  obligated  to pay any costs or expenses  incurred in
connection with the preparation,  execution,  recording or filing of the Severed
Loan  Documents,  and (ii) the  Severed  Loan  Documents  shall not  contain any
representations, warranties or covenants not contained in the Loan Documents and
any such  representations and warranties contained in the Severed Loan Documents
will be given by Borrower only as of the Closing Date.

     Section 8.3 REMEDIES CUMULATIVE; WAIVERS.

     The rights,  powers and  remedies of Lender under this  Agreement  shall be
cumulative  and not  exclusive of any other right,  power or remedy which Lender
may  have  against  Borrower  pursuant  to  this  Agreement  or the  other  Loan
Documents, or existing at law or in equity or otherwise. Lender's rights, powers
and remedies may be pursued singly,  concurrently or otherwise, at such time and
in such order as Lender may determine in Lender's sole  discretion.  No delay or
omission  to  exercise  any  remedy,  right or power  accruing  upon an Event of
Default shall impair any such remedy,  right or power or shall be construed as a
waiver thereof,  but any such remedy,  right or power may be exercised from time
to time and as often as may be  deemed  expedient.  A waiver of one  Default  or
Event of Default with respect to Borrower  shall not be construed to be a waiver
of any  subsequent  Default  or Event of Default  by  Borrower  or to impair any
remedy, right or power consequent thereon.

     IX. SPECIAL PROVISIONS

     Section 9.1 SALE OF NOTES AND SECURITIZATION.

     At the  request  of the holder of the Note and,  to the extent not  already
required to be provided by Borrower  under this  Agreement,  Borrower  shall use
reasonable  efforts to satisfy the market  standards  to which the holder of the
Note customarily  adheres or which may be reasonably required in the marketplace
or by  the  Rating  Agencies  in  connection  with  the  sale  of  the  Note  or
participations therein or the first successful  securitization (such sale and/or
securitization,  the "Securitization") of rated single or multi-class securities
(the "Securities")  secured by or evidencing ownership interests in the Note and

     (a) (i) provide such  financial and other  information  with respect to the
Property,  Borrower and the Manager which is customarily maintained by Borrower,
(ii) provide budgets relating to the Property which is customarily maintained by

engineering reports and other due diligence  investigations of the Property,  as
may be reasonably  requested by the holder of the Note or the Rating Agencies or
as may be necessary or appropriate in connection  with the  Securitization  (the
"Provided Information"),  together, if customary,  with appropriate verification
and/or  consents  of the  Provided  Information  through  letters of auditors or
opinions of counsel of independent attorneys acceptable to Lender and the Rating
Agencies;

     (b) at Lender's  expense,  cause counsel to render  opinions,  which may be
relied upon by the holder of the Note, the Rating Agencies and their  respective
counsel,  agents  and  representatives,  as  to  non-consolidation,   fraudulent
conveyance,  and true  sale  and/or  lease or any  other  opinion  customary  in
securitization  transactions,  which  counsel and opinions  shall be  reasonably
satisfactory to the holder of the Note and the Rating Agencies;

     (c) update such  representations  and warranties made in the Loan Documents
as of the  closing  date of the  Securitization  with  respect to the  Property,
Borrower,  and the Loan Documents as are customarily  provided in securitization
transactions and as may be reasonably requested by the holder of the Note or the
Rating Agencies; and

     (d)  execute  such  amendments  to the Loan  Documents  and  organizational
documents, enter into a lockbox or similar arrangement with respect to the Rents
as may be  requested  by the  holder  of the  Note  or the  Rating  Agencies  or


                                      -34-
<PAGE>
otherwise to effect the Securitization;  provided,  however, that Borrower shall
not be required to modify or amend any Loan  Document  if such  modification  or
amendment  would (i) change  the  interest  rate,  the  stated  maturity  or the
amortization  of  principal  set forth in the Note,  or (ii) modify or amend any
other material  economic term of the Loan or materially  increase any liability,
indemnity or other obligation.

     (e) If  requested  by  Lender,  Borrower  shall  provide  Lender  with  the
following  financial  statements (it being  understood that Lender shall request
such  financial  statements if it anticipates  that the principal  amount of the
Loan at the time of  Securitization  may, or if the principal amount of the Loan
at any time during which the Loan is included in a Securitization  does,  equals
or exceeds 20% of the aggregate  principal amount of all mortgage loans included
in the  Securitization),  and  summaries  of such  financial  statements  if the
principal  amount of the Loan at any such time  equals  or  exceeds  10% of such
aggregate principal amount:

          (i) As of the  Closing  Date,  a balance  sheet  with  respect  to the
     Property for the two most recent fiscal years,  meeting the requirements of
     Section  210.3-01  of  Regulation  S-X of the  Securities  Act of 1933,  as
     amended, and statements of income and statements of cash flows with respect
     to the  Property  for the three  most  recent  fiscal  years,  meeting  the
     requirements of Section 210.3-02 of Regulation S-X, and, to the extent that
     such  balance  sheet is more  than 135  days  old as of the  Closing  Date,
     interim  financial  statements of the Property  meeting the requirements of
     Section  210.3-01 and  210.3-02 of  Regulation  S-X (all of such  financial
     statements,  collectively,  the "Standard Statements");  provided, however,
     that if the Property  would be deemed to constitute a business and not real
     estate  under  Regulation  S-X that has been  acquired by Borrower  from an
     unaffiliated  third party (an "Acquired  Property"),  as to which the other
     conditions set forth in Section 210.3-05 of Regulation S-X for provision of
     financial statements in accordance with such Section have been met, in lieu
     of the Standard Statements  otherwise required by this paragraph,  Borrower
     shall  instead  provide the financial  statements  acquired by such Section
     210.3-05 of Regulation S-X ("Acquired Property Statements").

          (ii) Not  later  than  thirty-eight  (38)  days  after the end of each
     fiscal quarter  following the Closing Date, a balance sheet of the Property
     as of the end of such fiscal quarter,  meeting the  requirements of Section
     210.3-01 of Regulation S-X, and statements of income and statements of cash
     flows of the Property for the period  commencing  following the last day of
     the most recent  fiscal year and ending on the date of such  balance  sheet
     and for the  corresponding  period of the most recent fiscal year,  meeting
     the requirements of Section  210.3-02 of Regulation S-X (provided,  that if
     for such  corresponding  period of the most  recent  fiscal  year  Acquired
     Property  Statements  were permitted to be provided  hereunder  pursuant to
     Section  9.1(e)(i) above,  Borrower shall instead provide Acquired Property
     Statements for such corresponding period). If requested by Lender, Borrower
     shall  also  provide  "summarized  financial  information,"  as  defined in
     Section  210.1-02(bb)  of Regulation  S-X,  with respect to such  quarterly
     financial statements.

          (iii)  Not later  than  eighty-three  (83) days  after the end of each
     fiscal year  following the Closing Date, a balance sheet of the Property as
     of the end of  such  fiscal  year,  meeting  the  requirements  of  Section
     210.3-01 of Regulation S-X, and statements of income and statements of cash
     flows of the  Property for such fiscal year,  meeting the  requirements  of
     Section 210.3-02 of Regulation S-X. If requested by Lender,  Borrower shall
     provide  summarized  financial  information  with  respect  to such  annual
     financial statements.

          (iv)  Within  ten (10)  Business  Days  after  notice  from  Lender in
     connection with the Securitization of this Loan, such additional  financial
     statements, such that, as of the date (each an "Offering Document Date") of
     each prospectus,  private placement memorandum,  offering circular or other
     offering document for such  Securitization  (each an "Offering  Document"),
     Borrower  shall have  provided  Lender  with all  financial  statements  as
     described in Section  9.1(e)(i)  above;  provided  that the fiscal year and
     interim periods for which such financial statements shall be provided shall
     be determined as of such Offering Document Date.

          (v)  In  the  event   Lender   determines,   in   connection   with  a
     Securitization,  that the financial  statements required in order to comply
     with  Regulation  S-X or Legal  Requirements  are  other  than as  provided
     herein,  then  notwithstanding  the provisions of this Section,  Lender may
     request, and Borrower shall promptly provide,  such combination of Acquired
     Property Statements and/or Standard Statements as may be necessary for such
     compliance.
                                      -35-
<PAGE>
          (vi) Any  other or  additional  financial  statements,  or  financial,
     statistical  or  operating  information,  as shall be required  pursuant to
     Regulation S-X or other Legal  Requirements in connection with any Offering
     Document or any filing under or pursuant to the Securities  Exchange Act in
     connection with or relating to a  Securitization  (hereinafter an "Exchange
     Act  Filing") or as shall  otherwise be  reasonably  requested by Lender to
     meet disclosure, rating agency or marketing requirements.

          (vii) All financial statements provided by Borrower hereunder shall be
     prepared in accordance with generally accepted accounting  principles,  and
     shall meet the  requirements of Regulation S-X and other  applicable  Legal
     Requirements.  All financial  statements relating to a fiscal year shall be
     audited  by  the  independent  accountants  in  accordance  with  generally
     accepted auditing standards,  Regulation S-X and all other applicable Legal
     Requirements,  shall be accompanied by the manually  executed report of the
     independent  accountants thereon,  which report shall meet the requirements
     of Regulation S-X and all other applicable Legal Requirements, and shall be
     further   accompanied  by  a  manually  executed  written  consent  of  the
     independent accountants, in form and substance acceptable to Lender, to the
     inclusion of such  financial  statements  in any offering  document and any
     Exchange  Act  Filing  and to  the  use of the  name  of  such  independent
     accountants and the reference to such independent  accountants as "experts"
     in any offering  document  and  Exchange Act Filing,  all of which shall be
     provided at the same time as the related financial  statements are required
     to be  provided,  provided  however  that  Lender  timely  provides to such
     accountants  such  information as is required by such accountants to render
     such  consent.  All  other  quarterly  financial  statements  which are not
     certified  by  Ernst & Young  shall be  certified  by the  chief  financial
     officer of Borrower,  which  certification  shall state that such financial
     statements to such person's  knowledge meet the  requirements  set forth in
     the first sentence of this paragraph.

Borrower  shall not be  obligated  to pay any third  party  costs or expenses in
connection  with  a  Securitization   other  than  (i)  costs  relating  to  the
indemnification  obligations  set forth herein and (ii) costs  relating to items
already required to be provided by Borrower under this Agreement.

     Section 9.2 SECURITIZATION INDEMNIFICATION.

     (a) In connection with a  Securitization,  Borrower agrees (i) to indemnify
Lender  and its  Affiliates  for any  losses,  claims,  damages  or  liabilities
(collectively,  the  "Liabilities") to which Lender or its Affiliates may become
subject  insofar  as the  Liabilities  arise out of or are based upon any untrue
statement  or alleged  untrue  statement  of any  material  fact in the Provided
Information  or arise out of or are based upon the omission or alleged  omission
to state in the Provided  Information  a material  fact required to be stated in
the  Provided  Information  necessary  in order to make  the  statements  in the
Provided  Information,  in light of the circumstances under which they were made
not misleading and (ii) to reimburse  Lender and its Affiliates for any legal or
other  expenses  reasonably  incurred by Lender or its  Affiliates in connection
with defending or investigating the Liabilities.

     (b) The  liabilities and obligations of both Borrower and Lender under this
Section 9.2 shall survive the termination of this Agreement and the satisfaction
and discharge of the Debt.

     Section 9.3 INTENTIONALLY OMITTED.

     Section 9.4 EXCULPATION.

     Subject to the qualifications below, Lender shall not enforce the liability
and obligation of Borrower to perform and observe the  obligations  contained in
the Note, this Agreement, the Mortgage or the other Loan Documents by any action
or proceeding  wherein a money judgment shall be sought  against  Borrower,  its
partners, officers,  directors,  employees or agents (the "Exculpated Parties"),
except  that  Lender may bring a  foreclosure  action,  an action  for  specific
performance  or any other  appropriate  action or proceeding to enable Lender to
enforce  and realize  upon its  interest  under the Note,  this  Agreement,  the
Mortgage and the other Loan  Documents,  or in the Property,  the Rents,  or any
other  collateral  given to Lender  pursuant  to the Loan  Documents;  provided,
however,  that, except as specifically provided herein, any judgment in any such
action or proceeding shall be enforceable against Borrower only to the extent of
Borrower's  interest in the Property,  in the Rents and in any other  collateral
given to Lender, and Lender, by accepting the Note, this Agreement, the Mortgage
and the other Loan  Documents,  agrees that it shall not sue for, seek or demand
any deficiency  judgment  against the  Exculpated  Parties in any such action or
proceeding  under or by reason of or under or in connection  with the Note, this

                                      -36-
<PAGE>
Agreement,  the Mortgage or the other Loan  Documents.  The  provisions  of this
section shall not,  however,  (a) constitute a waiver,  release or impairment of
any obligation evidenced or secured by any of the Loan Documents; (b) impair the
right of Lender to name Borrower as a party  defendant in any action or suit for
foreclosure  and sale under any of the Mortgage;  (c) impair the right of Lender
to obtain the  appointment  of a  receiver;  (d) impair the  enforcement  of the
Assignment of Leases;  (e)  constitute a prohibition  against Lender to commence
any other  appropriate  action or proceeding in order for Lender to exercise its
remedies  against the Property (y) as set forth in the Loan  Documents or (z) as
are available  under  applicable law; or (f) constitute a waiver of the right of
Lender to enforce the liability and obligation of Borrower, by money judgment or
otherwise,  to the extent of any actual loss, damage, cost, expense,  liability,
claim or other  obligation  incurred by Lender  (including  attorneys'  fees and
costs reasonably incurred) arising out of or in connection with the following:

     (i)  fraud or intentional misrepresentation by Borrower or any guarantor in
          connection  with the Loan which has a material  adverse  effect of the
          Borrower;

     (ii) the gross negligence or willful misconduct of Borrower;

     (iii)the  breach  of  any  covenant  or  indemnification  provision  in the
          Environmental  Indemnity or in the Mortgage  concerning  environmental
          laws,  hazardous  substances and asbestos and any  indemnification  of
          Lender with respect thereto in either document;

     (iv) the removal or disposal by Borrower or its  affiliates  of any portion
          of the Property after an Event of Default;

     (v)  the  misapplication  or  conversion  by Borrower of (A) any  insurance
          proceeds  paid by  reason of any loss,  damage or  destruction  to the
          Property,  (B) any awards or other amounts received in connection with
          the condemnation of all or a portion of the Property, or (C) any Rents
          following an Event of Default;

     (vi) failure to pay charges for labor or  materials  or other  charges that
          can create liens on any portion of the Property;

     (vii)any  security  deposits,   advance  deposits  or  any  other  deposits
          collected  with  respect to the  Property  which are not  delivered to
          Lender upon a  foreclosure  of the Property or action in lieu thereof,
          except to the  extent  any such  security  deposits  were  applied  in
          accordance with the terms and conditions of any of the Leases prior to
          the  occurrence  of the  Event  of  Default  that  gave  rise  to such
          foreclosure or action in lieu thereof; and

   (viii) Borrower's  indemnifications  of Lender  set forth in  Section  9.2
          hereof.

     Notwithstanding anything to the contrary in this Agreement, the Note or any
of the Loan  Documents,  (A) Lender shall not be deemed to have waived any right
which  Lender  may have  under  Section  506(a),  506(b),  1111(b)  or any other
provisions  of the U.S.  Bankruptcy  Code to file a claim for the full amount of
the Debt  secured  by the  Mortgage  or to  require  that all  collateral  shall
continue to secure all of the Debt owing to Lender in  accordance  with the Loan
Documents,  and (B) the Debt shall be fully  recourse  to  Borrower in the event
that:  (i)  Borrower  fails to obtain  Lender's  prior  written  consent  to any
subordinate  financing or other voluntary Lien encumbering the Property; or (ii)
Borrower  fails to obtain  Lender's  prior  written  consent to any  assignment,
transfer,  or conveyance of the Property or any interest  therein as required by
the Mortgage or hereunder.

     Section 9.5 TERMINATION OF MANAGER.

     If (a) the Manager shall default after  applicable  notice and cure periods
have expired under the Management  Agreement,  (b) the amounts  evidenced by the
Note have  been  accelerated  pursuant  to  Section  8.1(b)  hereof,  (c) at the
Maturity  Date,  the Debt is not repaid in full, or (d) the Manager shall become
insolvent,  Borrower shall,  at the request of Lender,  terminate the Management
Agreement and replace the Manager with a manager approved by Lender on terms and
conditions  reasonably  satisfactory to Lender,  it being  understood and agreed
that the  management  fee for such  replacement  manager  shall not exceed  then
prevailing market rates.

     (A) THE LOAN WAS MADE BY LENDER AND  ACCEPTED  BY  BORROWER IN THE STATE OF
NEW YORK, AND THE PROCEEDS OF THE NOTE DELIVERED  PURSUANT HERETO WERE DISBURSED
FROM THE STATE OF NEW YORK,  WHICH  STATE THE  PARTIES  AGREE HAS A  SUBSTANTIAL

STATE OF NEW YORK SHALL GOVERN THE CONSTRUCTION,  VALIDITY AND ENFORCEABILITY OF
ALL LOAN DOCUMENTS AND ALL OF THE OBLIGATIONS  ARISING  HEREUNDER OR THEREUNDER.
TO THE FULLEST EXTENT  PERMITTED BY LAW,  BORROWER  HEREBY  UNCONDITIONALLY  AND
IRREVOCABLY  WAIVES ANY CLAIM TO ASSERT  THAT THE LAW OF ANY OTHER  JURISDICTION

PURSUANT TO SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW.

     (B) ANY LEGAL SUIT, ACTION OR PROCEEDING AGAINST LENDER OR BORROWER ARISING

in the  specific  instance,  and for the  purpose,  for which  given.  Except as
otherwise expressly provided herein, no notice to, or demand on Borrower,  shall
entitle Borrower to any other or future notice or demand in the same, similar or
other circumstances.

     Section 10.5 DELAY NOT A WAIVER.

     Neither any failure nor any delay on the part of Lender in  insisting  upon
strict performance of any term, condition,  covenant or agreement, or exercising
any right, power, remedy or privilege hereunder,  or under the Note or under any
other Loan Document,  or any other instrument given as security therefor,  shall
operate  as or  constitute  a waiver  thereof,  nor  shall a single  or  partial
exercise  thereof  preclude  any other future  exercise,  or the exercise of any
other  right,  power,  remedy or  privilege.  In  particular,  and not by way of
limitation,  by accepting payment after the due date of any amount payable under
this Agreement, the Note or any other Loan Document,  Lender shall not be deemed
to have waived any right either to require  prompt payment when due of all other
amounts due under this Agreement,  the Note or the other Loan  Documents,  or to
declare a default for failure to effect prompt payment of any such other amount.

     Section 10.7 TRIAL BY JURY.

     BORROWER HEREBY AGREES NOT TO ELECT A TRIAL BY JURY OF ANY ISSUE TRIABLE OF
RIGHT BY JURY,  AND WAIVES  ANY RIGHT TO TRIAL BY JURY FULLY TO THE EXTENT  THAT
ANY SUCH RIGHT SHALL NOW OR HEREAFTER  EXIST WITH REGARD TO THE LOAN  DOCUMENTS,
OR ANY CLAIM, COUNTERCLAIM OR OTHER ACTION ARISING IN CONNECTION THEREWITH. THIS
WAIVER OF RIGHT TO TRIAL BY JURY IS GIVEN KNOWINGLY AND VOLUNTARILY BY BORROWER,

     Section 10.8 HEADINGS.

     The  Article  and/or  Section  headings  and the Table of  Contents in this
Agreement are included  herein for  convenience  of reference only and shall not
constitute a part of this Agreement for any other purpose.

     Section 10.9 SEVERABILITY.

     Wherever possible, each provision of this Agreement shall be interpreted in
such  manner as to be  effective  and valid  under  applicable  law,  but if any
provision of this Agreement  shall be prohibited by or invalid under  applicable
law, such provision  shall be  ineffective to the extent of such  prohibition or
invalidity,  without  invalidating  the  remainder  of  such  provision  or  the
remaining provisions of this Agreement.

     Section 10.10 PREFERENCES.

     Lender shall have the  continuing  and exclusive  right to apply or reverse
and reapply any and all  payments by Borrower to any portion of the  obligations
of Borrower  hereunder.  To the extent  Borrower  makes a payment or payments to
Lender,  which  payment  or  proceeds  or  any  part  thereof  are  subsequently
invalidated, declared to be fraudulent or preferential, set aside or required to
be repaid to a trustee,  receiver or any other party under any  bankruptcy  law,
state or federal law, common law or equitable cause, then, to the extent of such
payment or proceeds received, the obligations hereunder or part thereof intended
to be satisfied  shall be revived and  continue in full force and effect,  as if
such payment or proceeds had not been received by Lender.

     Section 10.11 WAIVER OF NOTICE.

     Borrower shall not be entitled to any notices of any nature whatsoever from
Lender except with respect to matters for which this Agreement or the other Loan
Documents  specifically and expressly provide for the giving of notice by Lender
to  Borrower  and except  with  respect to matters  for which  Borrower  is not,
pursuant to  applicable  Legal  Requirements,  permitted  to waive the giving of
notice.  Borrower hereby  expressly  waives the right to receive any notice from
Lender  with  respect to any matter for which this  Agreement  or the other Loan
Documents do not specifically and expressly  provide for the giving of notice by
Lender to Borrower.

     Section 10.12 REMEDIES OF BORROWER.

     In the event that a claim or adjudication is made that Lender or its agents
have acted unreasonably or unreasonably  delayed acting in any case where by law
or under this Agreement or the other Loan  Documents,  Lender or such agent,  as
the case may be, has an  obligation  to act  reasonably  or  promptly,  Borrower
agrees  that  neither  Lender  nor its agents  shall be liable for any  monetary
damages,  and Borrower's  sole remedies shall be limited to commencing an action
seeking injunctive relief or declaratory judgment. The parties hereto agree that
any action or proceeding to determine  whether Lender has acted reasonably shall
be determined by an action seeking declaratory judgment.

     Section 10.13 EXPENSES; INDEMNITY.

     (a) Borrower  covenants and agrees to pay or, if Borrower  fails to pay, to
reimburse,  Lender upon receipt of written notice from Lender for all reasonable
costs and expenses  (including  reasonable  attorneys'  fees and  disbursements)
incurred  by  Lender  in  connection  with  (i)  the  preparation,  negotiation,
execution and delivery of this  Agreement  and the other Loan  Documents and the
consummation  of the  transactions  contemplated  hereby and thereby and all the
costs of  furnishing  all  opinions by counsel for Borrower  (including  without
limitation any opinions  reasonably  requested by Lender as to any legal matters
arising  under this  Agreement or the other Loan  Documents  with respect to the
Property); (ii) Borrower's ongoing performance of and compliance with Borrower's
respective  agreements  and covenants  contained in this Agreement and the other
Loan  Documents on its part to be  performed or complied  with after the Closing
Date; (iv) the negotiation,  preparation, execution, delivery and administration
of any consents,  amendments,  waivers or other  modifications to this Agreement
and the other Loan  Documents  and any other  documents or matters  requested by
Lender;  (v) securing  Borrower's  compliance with any requests made pursuant to
the  provisions  of this  Agreement;  (vi) the  filing  and  recording  fees and
expenses,  title  insurance  and  reasonable  fees and  expenses  of counsel for
providing to Lender all required  legal  opinions,  and other  similar  expenses
incurred in creating and perfecting the Lien in favor of Lender pursuant to this
Agreement  and the other Loan  Documents;  (vii)  enforcing  or  preserving  any
rights, in response to third party claims or the prosecuting or defending of any


                                      -40-
<PAGE>
action  or  proceeding  or other  litigation,  in each  case  against,  under or
affecting Borrower, this Agreement,  the other Loan Documents,  the Property, or
any other security given for the Loan; and (viii)  enforcing any  obligations of
or collecting  any payments due from Borrower  under this  Agreement,  the other
Loan  Documents  or with  respect  to the  Property  or in  connection  with any
refinancing  or  restructuring  of the credit  arrangements  provided under this
Agreement  in the nature of a  "work-out"  or of any  insolvency  or  bankruptcy
proceedings;  provided,  however,  that  Borrower  shall not be  liable  for the
payment of any such costs and expenses to the extent the same arise by reason of
the gross negligence,  illegal acts, fraud or willful  misconduct of Lender. Any
cost and  expenses due and payable to Lender may be paid from any amounts in the
Lockbox Account.

     (b) Borrower  shall  indemnify,  defend and hold  harmless  Lender from and
against any and all other liabilities,  obligations, losses, damages, penalties,
actions, judgments, suits, claims, costs, expenses and disbursements of any kind
or nature whatsoever  (including,  without  limitation,  the reasonable fees and
disbursements  of  counsel  for  Lender in  connection  with any  investigative,
administrative or judicial  proceeding  commenced or threatened,  whether or not
Lender shall be designated a party  thereto),  that may be imposed on,  incurred
by, or asserted  against Lender in any manner  relating to or arising out of (i)
any  breach  by   Borrower   of  its   obligations   under,   or  any   material
misrepresentation  by Borrower  contained  in, this  Agreement or the other Loan
Documents,  or  (ii)  the  use  or  intended  use of the  proceeds  of the  Loan
(collectively, the "Indemnified Liabilities");  provided, however, that Borrower
shall  not have any  obligation  to Lender  hereunder  to the  extent  that such
Indemnified Liabilities arise from the gross negligence,  illegal acts, fraud or
willful  misconduct of Lender.  To the extent that the undertaking to indemnify,
defend  and  hold  harmless  set  forth  in  the   preceding   sentence  may  be
unenforceable  because it violates any law or public policy,  Borrower shall pay
the maximum portion that it is permitted to pay and satisfy under applicable law
to the payment  and  satisfaction  of all  Indemnified  Liabilities  incurred by
Lender.

     Section 10.14 SCHEDULES INCORPORATED.

     The Schedules  annexed hereto are hereby  incorporated  herein as a part of
this Agreement with the same effect as if set forth in the body hereof.

     Section 10.15 OFFSETS, COUNTERCLAIMS AND DEFENSES.

     Any assignee of Lender's  interest in and to this  Agreement,  the Note and
the other  Loan  Documents  shall  take the same free and clear of all  offsets,
counterclaims  or defenses which are unrelated to such documents  which Borrower
may otherwise have against any assignor of such documents, and no such unrelated
counterclaim  or defense  shall be  interposed  or  asserted  by Borrower in any
action or proceeding  brought by any such  assignee upon such  documents and any
such right to interpose or assert any such  unrelated  offset,  counterclaim  or
defense in any such action or proceeding is hereby expressly waived by Borrower.

     Section   10.16  NO  JOINT   VENTURE  OR   PARTNERSHIP;   NO  THIRD   PARTY
BENEFICIARIES.

     (a) Borrower and Lender intend that the relationships created hereunder and
under the other Loan  Documents be solely that of borrower  and lender.  Nothing
herein  or  therein  is  intended  to  create  a  joint  venture,   partnership,
tenancy-in-common, or joint tenancy relationship between Borrower and Lender nor
to grant  Lender any  interest  in the  Property  other than that of  mortgagee,
beneficiary or lender.

     (b) This  Agreement and the other Loan Documents are solely for the benefit
of Lender and Borrower and nothing contained in this Agreement or the other Loan
Documents  shall be deemed to confer upon anyone  other than Lender and Borrower
any right to insist upon or to enforce the  performance  or observance of any of
the obligations  contained herein or therein.  All conditions to the obligations
of Lender to make the Loan hereunder are imposed solely and  exclusively for the
benefit  of  Lender  and  no  other  Person  shall  have   standing  to  require
satisfaction of such conditions in accordance with their terms or be entitled to
assume  that  Lender  will  refuse  to make the Loan in the  absence  of  strict
compliance  with  any or all  thereof  and  no  other  Person  shall  under  any
circumstances  be deemed to be a beneficiary of such  conditions,  any or all of
which may be freely  waived in whole or in part by Lender if, in  Lender's  sole
discretion, Lender deems it advisable or desirable to do so.





                                      -41-
<PAGE>
     Section 10.17 PUBLICITY.

     All news releases, publicity or advertising by Borrower or their Affiliates
through any media  intended to reach the general public which refers to the Loan
Documents or the financing  evidenced by the Loan Documents,  to Lender,  Lehman
Brothers Holdings Inc., or any of their Affiliates shall be subject to the prior
review and approval of Lender, such approval not to be unreasonably withheld.

     Section 10.18 WAIVER OF MARSHALLING OF ASSETS.

     To the  fullest  extent  permitted  by law,  Borrower,  for  itself and its
successors  and  assigns,  waives all rights to a  marshalling  of the assets of
Borrower,  Borrower's partners and others with interests in Borrower, and of the
Property,  and agrees not to assert any right under any laws  pertaining  to the
marshalling  of  assets,  the sale in  inverse  order of  alienation,  homestead
exemption,  the  administration  of estates of  decedents,  or any other matters
whatsoever  to  defeat,  reduce  or affect  the  right of Lender  under the Loan
Documents to a sale of the Property for the  collection  of the Debt without any
prior or  different  resort  for  collection  or of the  right of  Lender to the
payment of the Debt out of the net  proceeds of the  Property in  preference  to
every other claimant whatsoever.

     Section 10.19 WAIVER OF COUNTERCLAIM.

     Borrower  hereby  waives the right to assert a  counterclaim,  other than a
compulsory  counterclaim,  in any  action or  proceeding  brought  against it by
Lender or its agents.

     SECTION 10.20 CONFLICT; CONSTRUCTION OF DOCUMENTS; RELIANCE.

     In the event of any conflict  between the provisions of this Loan Agreement
and any of the other Loan Documents, the provisions of this Loan Agreement shall
control.  The parties hereto acknowledge that they were represented by competent
counsel in connection with the  negotiation,  drafting and execution of the Loan
Documents and that such Loan Documents  shall not be subject to the principle of
construing  their  meaning  against  the  party  which  drafted  same.  Borrower
acknowledges  that, with respect to the Loan,  Borrower shall rely solely on its
own  judgment  and  advisors in entering  into the Loan  without  relying in any
manner on any statements,  representations  or  recommendations of Lender or any
parent,  subsidiary  or Affiliate of Lender.  Lender shall not be subject to any
limitation  whatsoever in the exercise of any rights or remedies available to it
under any of the Loan  Documents or any other  agreements or  instruments  which
govern the Loan by virtue of the  ownership by it or any parent,  subsidiary  or
Affiliate of Lender of any equity  interest any of them may acquire in Borrower,
and Borrower  hereby  irrevocably  waives the right to raise any defense or take
any action on the basis of the  foregoing  with respect to Lender's  exercise of
any such rights or remedies.  Borrower  acknowledges  that Lender engages in the
business  of real  estate  financings  and other real  estate  transactions  and
investments  which may be viewed as adverse to or competitive  with the business
of Borrower or its Affiliates.

     Section 10.21 BROKERS AND FINANCIAL ADVISORs.

     Borrower hereby  represents  that it has dealt with no financial  advisors,
brokers,  underwriters,  placement agents,  agents or finders in connection with
the  transactions  contemplated  by this  Agreement.  Borrower  hereby agrees to
indemnify,  defend and hold Lender harmless from and against any and all claims,
liabilities,  costs and expenses of any kind (including Lender's attorneys' fees
and  expenses) in any way relating to or arising from a claim by any Person that
such  Person  acted on behalf of Borrower in  connection  with the  transactions
contemplated  herein.  The  provisions  of this Section  10.21 shall survive the
expiration and termination of this Agreement and the payment of the Debt.

     Section 10.22 PRIOR AGREEMENTS.

     This Agreement and the other Loan Documents contain the entire agreement of
the  parties  hereto and  thereto in  respect of the  transactions  contemplated
hereby and thereby,  and all prior  agreements  among or between  such  parties,
whether oral or written, between Borrower and Lender are superseded by the terms
of this Agreement and the other Loan Documents.

2.2 BORROWING PROCEDURES.

     Lender shall have received,  on or before 11:00 a.m.  Chicago time, one (1)
Business Day prior to the date a Loan is to be made,  if a Reference  Rate Loan,
or  three  (3)  Business  Days  prior  to the  date a Loan is to be  made,  if a

designation  whether the Loan is to be a  Eurodollar  Loan or a  Reference  Rate
Loan,  and if such  Loan is to be a  Eurodollar  Loan,  the  Interest  Period or

which the Borrower is required to deliver to Lender  hereunder.  If such request

Eurodollar  Loan in such notice,  then Borrower shall be deemed to have selected

     (b)  After the occurrence of an Event of Default  resulting from failure to
          pay any Obligations hereunder,  Lender may (but shall not be obligated
          to) debit the  amount  of any such  payment  which is not made by such
          time to any ordinary deposit account of Borrower with Lender and shall
          give notice thereof to the Borrower, provided the failure to give such
          notice does not affect the validity of such debit.

     (c)  Borrower  shall,  at the  time  of  making  such  payment  under  this
          Agreement  or the  Note,  specify  to the  Lender  the  Loans or other

          applied.  Absent receipt of such notice from the Borrower,  the Lender
          may apply any  payments  received  from the  Borrower  in any order or
          priority determined by the Lender in its sole discretion.

          successive Business Day, at the office of the Lender.

     (e)  Except as otherwise provided in Section 2.10 hereof, any prepayment of
          the Obligations by Borrower shall be without premium or penalty, other
          than the imposition of the Default Rate of interest, where applicable.

          Borrower  to  the  Lender,  including  statements  of  all  principal,
          interest,  and Out-of-Pocket Fees and Costs owing, and such statements

          constitute  an account  stated  between  the  Borrower  and the Lender
          unless, within thirty (30) days after receipt thereof by the Borrower,
          the Borrower  shall  deliver to the Lender,  at the Lender's  place of
          business  indicated in Section 14 hereof,  written  objection  thereto

          Borrower's  account,  and less any  other  sums due to the  Lender  as
          provided in this Agreement, shall be remitted to the Borrower when all
          Obligations owed by the Borrower to the Lender have been paid in full.

     2.4 INTENTIONALLY DELETED.

     2.5 INTEREST.

     (a)  All Obligations  owed by the Borrower to Lender (except for Eurodollar
          Loans and those Obligations  evidenced by a promissory note other than
          the Note, or covered by any other  Section of this  Agreement or other
          agreement which specifically provides for a rate of interest different
          from that  provided  for herein)  shall bear  interest,  on the unpaid
          principal balance thereof,  at a rate per annum (computed on the basis
          of the actual number of days elapsed over a 360 day year) (the "Rate")
          equal to the Reference  Rate,  payable monthly in arrears on the first
          Business Day of each calendar month.

          Each  Eurodollar  Loan shall  bear  interest  on the unpaid  principal
          balance  thereof  at a rate per  annum  (computed  on the basis of the
          actual  number of days elapsed over a 360-day year) equal to the Libor
          Rate for the  Interest  Period in effect  for such Loan,  plus  1.95%.
          Interest  on  Eurodollar  Loans  shall be  payable  in  arrears on the
          earlier of (i) last day of each calendar  month during the  applicable
          Interest Period, or (ii) on the last day of such Interest Period.

          In addition to  calculations  of the Rate as  provided  above,  in the
          event  that  the  Reference  Rate  announced  is,  from  time  to time
          hereafter,  changed,  adjustment  in the  Rate  shall  be  made on the
          effective  date of such change in the  Reference  Rate.  The Rate,  as
          adjusted,  shall apply to all  Obligations  (except as provided  above


                                      -8-
<PAGE>
          with  respect  to  Eurodollar  Loans or where  otherwise  specifically
          provided)  owed on the date following the date on which the adjustment
          is made and shall  continue to apply to such  Obligations  owed during
          succeeding  months until the Reference Rate is adjusted again.  Lender
          shall use reasonable  efforts to notify Borrower of each change in the
          Reference Rate as soon as  practicable,  but Borrower's  obligation to
          pay all  interest  at the Rate and  Default  Rate as  provided in this
          Agreement  shall  not be  affected  by,  nor  shall  Lender  have  any
          liability for, any failure to so notify Borrower.

     (b)  Notwithstanding  the foregoing,  the Obligations  shall bear interest,
          from and after the  occurrence  of an Event of Default and for so long
          as an Event  of  Default  shall  be an  Uncured  Default  and  without
          constituting  a waiver of any such Event of Default,  on the  balances
          owing  from  time to  time,  at a rate  per  annum  equal  to four (4)
          percentage  points  above the Rate (the  "Default  Rate"),  payable on
          demand.  In  addition,  the  Borrower  shall pay to the  Lender a late
          charge  equal to three (3) percent of any amount of  principal  and/or
          interest and/or charges on the Loans which is not paid within ten (10)
          days of the date when due.

     (c)  It is the  intention of Lender and Borrower to comply with the laws of
          the  State of  Illinois,  and  notwithstanding  any  provision  to the
          contrary  contained  herein or in the other Loan  Documents,  Borrower
          shall not be required to pay,  and Lender  shall not be  permitted  to
          collect,  any  amount  in  excess of the  maximum  amount of  interest
          permitted  by  applicable  law  ("Excess  Interest").  If  any  Excess
          Interest is provided for or  determined to have been provided for by a
          court of  competent  jurisdiction  in this  Agreement or in any of the
          other Loan  Documents,  then in such event (i) the  provisions of this
          Section shall govern and control; (ii) Borrower shall not be obligated
          to pay any Excess Interest;  (iii) any Excess Interest that Lender may
          have received hereunder shall be, at Lender's option, (A) applied as a
          credit against either the outstanding  principal  balance of the Loans
          or accrued  and unpaid  interest  hereon,  (B)  refunded  to the payor
          thereof,  or (C) any  combination of the foregoing;  (iv) the interest
          rate(s)  provided  for herein  shall be  automatically  reduced to the
          maximum rate allowed under  applicable law, and this Agreement and the
          other  Loan  Documents  shall be  deemed to have  been,  and shall be,
          reformed  and  modified to reflect  such  reduction;  and (v) Borrower
          shall not have any action against  Lender for any damages  arising out
          of the payment or collection of any Excess  Interest.  Notwithstanding
          the foregoing,  if any interest payment or other charge or fee payable
          hereunder or under any of the other Loan Documents exceeds the maximum
          amount then permitted by applicable law, then to the extent  permitted
          by law,  Borrower  shall be obligated  to pay the maximum  amount then
          permitted by  applicable  law and Borrower  shall  continue to pay the
          maximum amount from time to time permitted by applicable law until all
          such  interest  payments  and other  charges  and fees  otherwise  due
          hereunder or under any of the other Loan  Documents (in the absence of
          such restraint imposed by applicable law) have been paid in full.

     (d)  Lender  may,  upon  notice to  Borrower,  at its  option,  charge  any
          interest  and fees  payable  hereunder  or under any of the other Loan
          Documents to Borrower's Loan Account, and any amounts so charged shall
          thereupon constitute Obligations hereunder and shall thereafter accrue
          interest as provided for in this Agreement.

     2.6 FEES.

     In consideration of Lender' establishing the Maximum Facility hereunder and
making of the Loans hereunder,  Borrower shall pay to the Lender,  the following

          same or a different  type from Lender,  subject to the  conditions and
          limitations  set forth  herein and  elsewhere in this  Agreement.  Any
          Eurodollar  Loan or part  thereof  so  renewed  shall be  deemed to be
          repaid in  accordance  with this  Section 2 with the proceeds of a new
          borrowing  hereunder  and the proceeds of the new Loan,  to the extent
          such  proceeds do not exceed the  principal  amount of the  Eurodollar
          Loan  being  renewed,  shall not be paid by the  Lender  to  Borrower.
          Nothing in this Section  2.9(a)  shall be deemed a  limitation  on the

     (b)  The  Borrower  shall  have the right at any time,  upon  notice to the
          Lender  given  in the  manner  and  at the  times  specified  in  this
          Agreement  with  respect  to  the  Loans  into  which   conversion  or
          continuation  is to be made,  to  convert  its  Eurodollar  Loans into
          Reference  Rate  Loans,  to  convert  its  Reference  Rate  Loans into
          Eurodollar  Loans  (specifying  the Interest  Period to be  applicable
          thereto),  to convert the  Interest  Period  applicable  to any of its
          Eurodollar  Loans  to  another  permissible  Interest  Period,  and to
          continue any of its Eurodollar Loans into a subsequent Interest Period
          of any  permissible  duration,  subject to the terms and conditions of
          this Agreement, and to the following:

          (i)  each  conversion  shall be  effected  by Lender by  applying  the
               proceeds of the new Reference  Rate Loan or  Eurodollar  Loan, as
               the case may be, to the Reference  Rate Loan or  Eurodollar  Loan
               (or portion thereof) being converted;  accrued interest on a Loan
               (or portion  thereof) being  converted or continued shall be paid
               by the Borrower at the time of conversion or continuation; and

          (ii) If any  Eurodollar  Loan is  converted at any time other than the
               end of an Interest Period applicable thereto,  the Borrower shall
               make such payments associated  therewith as are required pursuant
               to  Section  2.10 at the  time  such  Eurodollar  Loan  shall  be
               converted to a Reference Rate Loan.

The  Interest  Period  applicable  to  any  Eurodollar  Loan  resulting  from  a
conversion or  continuation  shall be specified by the Borrower in the notice of
conversion or continuation delivered pursuant to this provided, however, that if
no such Interest Period shall be specified, the Borrower shall be deemed to have

     2.10 INDEMNITY.

     The Borrower  shall  indemnify  the Lender  against any loss,  fee,  claim,
damage,  liability  or  expense  which  the  Lender  may  sustain  or incur as a
consequence  of (i) any  failure by the  Borrower  to fulfill on the date of any
borrowing of a Eurodollar Loan hereunder the applicable  conditions set forth in
this  Agreement,  (ii) any  failure by the  Borrower to borrow  hereunder  after
notice  of  borrowing  pursuant  to this  Agreement  has been  given,  (iii) any
payment, prepayment or conversion of a Eurodollar Loan required by any provision
of this  Agreement,  or otherwise  made on a date other than the last day of the
applicable  Interest  Period,  or (iv) the  occurrence  of any Event of Default,
including,  but not limited to, any loss or expense  sustained or incurred or to
be sustained or incurred in liquidating or employing deposits from third parties
acquired to effect or  maintain  such Loan or any part  thereof as a  Eurodollar
Loan. Such loss or expense shall include, without limitation, an amount equal to
the  excess,  if any,  as  reasonably  determined  by the  Lender of its cost of
obtaining the funds for the Eurodollar Loan being paid,  prepaid or converted or
not borrowed  (based on the Libor Rate  applicable  thereto) for the period from
the date of such  payment,  prepayment or conversion or failure to borrow to the
last day of the Interest  Period for such  Eurodollar Loan (or, in the case of a
failure to borrow, the Interest Period for such Eurodollar Loan which would have
commenced on the date of such failure to borrow) over the amount of interest (as
reasonably  determined  by the  Lender)  that could be realized by the Lender in
re-employing  during such period the funds so paid,  prepaid or converted or not
borrowed.  A certificate of the Lender setting forth any amount or amounts which
the  Lender is  entitled  to  receive  pursuant  to this  Section  2.10 shall be
conclusive absent manifest error.

     2.11 CHANGE IN LEGALITY.

     (a)  Notwithstanding  anything to the  contrary  herein  contained,  if any
          change in any law or  regulation or in the  interpretation  thereof by
          any  governmental   authority  charged  with  the   administration  or
          interpretation  thereof  shall make it unlawful for the Lender to make
          or maintain any Eurodollar  Loan or to give effect to its  obligations
          as contemplated hereby (an "Illegality"),  or if the Lender determines
          that  maintenance  of  Eurodollar  Loans  would  cause  the  Lender to
          implement  or modify any reserve,  special  deposit or  assessment  or
          other  requirement,  or  impose  any  other  condition  on the  Lender
          affecting  the Loans  (each of the  foregoing  circumstances  called a
          "Regulatory  Action"),  then, by written  notice to the Borrower,  the
          Lender shall:

          (i)  declare that Eurodollar  Loans will not thereafter be made by the
               Lender hereunder, whereupon the Borrower shall be prohibited from
               requesting Eurodollar Loans from the Lender hereunder unless such
               declaration is subsequently withdrawn; provided, however, that if
               after  the date of any such  declaration  there  shall  occur any
               change in law or regulation or in the  interpretation  thereof by
               any  government  authority  charged  with the  administration  or
               interpretation thereof that shall eliminate such Illegality,  the
               Lender  shall as promptly as  reasonably  practicable  notify the
               Borrower of such occurrence and withdraw such declaration; and

          (ii) require that all outstanding  Eurodollar Loans made by the Lender
               be converted to Reference Rate Loans, in which event (1) all such
               Eurodollar  Loans shall be  automatically  converted to Reference
               Rate Loans as of the effective date of such notice as provided in
               paragraph  (b) below and,  (2) all payments  and  prepayments  of
               principal  which would  otherwise  have been applied to repay the
               converted  Eurodollar Loans shall instead be applied to repay the
               Reference  Rate  Loans  resulting  from  the  conversion  of such
               Eurodollar Loans.

     (b)  for  purposes  of this  Section  2.11 a notice to the  Borrower by the
          Lender  pursuant to paragraph (a) above shall be effective on the date
          of receipt by the Borrower.

     2.12 UNAVAILABILITY OF DEPOSITS OR INABILITY TO ASCERTAIN, OR INADEQUACY OF
LIBOR RATE.

     If on or prior to the first day of any Interest Period for any Borrowing of
Eurodollar Loans, the Lender advises the Borrower that deposits in United States
Dollars (in the applicable amounts) are not being offered to it in the off-shore
U.S.  Dollar  interbank  market for such Interest  Period,  whereupon  until the
Lender  notifies  the  Borrower  that  the  circumstances  giving  rise  to such


                                      -11-
<PAGE>
suspension no longer exist,  the  obligations  of the Lender to make  Eurodollar
Loans shall be suspended without liability to the Lender.

     2.13 INCREASED COST AND REDUCED RETURN.

     (a)  If on or after the date hereof,  the adoption of any  applicable  law,
          rule or  regulation,  or any  change  therein,  or any  change  in the
          interpretation   or   administration   thereof  by  any   governmental
          authority,   central  bank  or  comparable  agency  charged  with  the
          interpretation or administration  thereof, or compliance by the Lender
          with any request or directive (whether or not having the force of law)
          of any such authority, central bank or comparable agency:

          (i)  shall  subject the Lender to any tax,  duty or other  charge with
               respect to its  Eurodollar  Loans,  its Note or its obligation to
               make  Eurodollar  Loans, or shall change the basis of taxation of
               payments  to the Lender of the  principal  of or  interest on its
               Eurodollar Loans or any other amounts due under this Agreement in
               respect  of its  Eurodollar  Loans  or  its  obligation  to  make
               Eurodollar  Loans  (except  for changes in the rate of tax on the
               overall net income of the Lender imposed by the  jurisdiction  in
               which the Lender's principal executive office is located);

          (ii) shall  impose,  modify or deem  applicable  any reserve,  special
               deposit or similar  requirement  (including,  without limitation,
               any such  requirement  imposed by the Board of  Governors  of the
               Federal Reserve  System,  against assets of, deposits with or for
               the account of, or credit extended by, the Lender or shall impose
               on the  Lender or on the  interbank  market  any other  condition
               affecting its  Eurodollar  Loans,  its Note or its  obligation to
               make Eurodollar Loans; or

          (iii)shall  impose on the Lender  any other  condition  affecting  the
               Loans;

and the result of any of the  foregoing is to increase the cost to the Lender of
making or maintaining  any  Eurodollar  Loan, or to reduce the amount of any sum
received or receivable by the Lender under this Agreement or under its Note with
respect thereto,  by an amount deemed reasonably and in good faith by the Lender
to be material,  then,  Borrower shall, within fifteen (15) days after demand by
the Lender,  be obligated to pay the Lender such additional amount or amounts as
will  compensate  the  Lender for such  increased  cost or  reduction  (computed
commencing  on the effective  date of any event  mentioned  herein).  The Lender
agrees to use its best efforts to give the Borrower  notice of the occurrence of
any event  mentioned  herein.  In addition,  the Lender may,  upon notice to the
Borrower, elect to increase the interest rate applicable to all Eurodollar Loans
made  subsequent  thereto,  to compensate  the Lender for such increased cost or
reduced yield.

     2.14 DISCRETION OF THE LENDER AS TO MANNER OF FUNDING.

     Notwithstanding any other provision of this Agreement,  the Lender shall be
entitled to fund and maintain its funding of all or any part of its Loans in any
manner it sees fit, it being understood,  however, that for the purposes of this
Agreement  all  determinations  hereunder  shall  be made as if the  Lender  had
actually  funded and  maintained  each  Eurodollar  Loan through the purchase of
deposits  in the  interbank  market  having  a  maturity  corresponding  to such
Eurodollar  Loan's  Interest  Period and bearing an  interest  rate equal to the
Libor Rate for such Interest Period.

          Default,  the  Lender  may,  in  accordance  with  Section  11 of this

          terminate automatically upon an Event of Default under Section 10.5 or

remedies not inconsistent herewith as provided by law, or in equity. No exercise
by the Lender of one right or remedy shall be deemed an election,  and no waiver

therefor,  and the Borrower shall promptly  reimburse the Lender.  All such sums
shall become additional  Obligations owing to the Lender and shall bear interest
at the  Default  Rate  hereunder.  Any  payments  made by the  Lender  shall not
constitute:  (i) agreement by the Lender to make similar payments in the future,
or (ii) a waiver by the Lender of any Event of Default under this Agreement. the
Lender need not inquire as to, or contest the validity of, any such expense, tax
or Lien and the receipt of the usual  official  notice for the  payment  thereof
shall be conclusive  evidence  that the same was validly due and owing,  and the
receipt of any other notice with respect to all other such monies due  hereunder
shall be prima facia evidence that the same was validly due and owing.

     13. CERTAIN WAIVERS.

delivered  personally  or otherwise  actually  received,  (ii) sent by overnight
delivery  service,  (iii) mailed by  first-class  United  States  mail,  postage
prepaid,  registered or certified,  with return receipt requested,  or (iv) sent
via  telecopy  machine  with a  duplicate  signed  copy  sent on the same day as
provided in clause (ii) above.  Notice  mailed as provided in clause (iii) above
shall be effective  upon the  expiration  of three (3)  Business  Days after its

delivery  thereof is refused by such  addressee,  such notice shall be effective
upon such tender unless expressly set forth in such notice.

     15. CHOICE OF LAW AND VENUE.

     This  Agreement and each of the other Loan  Documents  (except as otherwise
specifically provided therein) shall be deemed to have been made in the State of
Illinois and the validity of this Agreement and the other Loan Documents,  their
construction,   interpretation  and  enforcement,  shall  be  determined  under,
governed by and construed in accordance  with the laws of the State of Illinois.
The parties agree that all actions or  proceedings  arising in  connection  with
this  Agreement  and each of the  other  Loan  Documents  (except  as  otherwise
specifically  provided  therein)  shall be tried and litigated only in the state
and  federal  courts  located  in the  County of Cook,  State of  Illinois.  The
Borrower  waives  any  right it may have to  assert  the  doctrine  of forum non
conveniens  or to object to such venue and hereby  consents to any court ordered
relief.  The  Borrower  consents  that all service of process upon it be made by
registered mail or messenger  directed to it at the address set forth in Section
14 above and that  service  so made  shall be deemed  to be  completed  upon the
earlier of actual  receipt or three (3) Business  Days after the same shall have
been  posted to the  Borrower's  address  by the  Borrower's  agent as set forth
below. Nothing contained in this Section 15 shall affect the right of the Lender
to serve legal process in any other manner  permitted by law or affect the right
of the Lender to bring any action or proceeding against the Borrower, Company or
any  Guarantor  Subsidiaries  or  their  property  in the  courts  of any  other
jurisdiction.  Without  limiting  the  foregoing,  in  addition to the state and
federal courts of Illinois,  the Lender may bring action(s) for enforcement on a
non-exclusive  basis in the state or federal  courts of Indiana  with respect to
the  Security  Documents,  and the  Borrower  consents  (on behalf of itself and
Mortgagor) to the  non-exclusive  jurisdiction of such courts and the service of
process  in any  such  suit  being  made  upon the  Mortgagor  and  Borrower  by
registered mail or messenger at the address specified in Section 14 above.

     16. INDEMNITY.

     Borrower  shall  indemnify,  hold  harmless  and  defend the Lender and its
directors,  officers, agents, counsel and employees ("Indemnified Persons") from
and  against  all losses,  claims,  damages,  costs,  expenses  and  liabilities
("Losses"),  whether  such  Losses  arise or notice  thereof is  received by the
Lender during the term of this Agreement or after termination of this Agreement,
incurred  by  any  of  them  arising  principally  out of or  relating  to  this
Agreement,  the  Loans,  the  other  Loan  Documents  or any  other  transaction
contemplated  hereby or thereby,  other than  arising  out of any  intercreditor
relationship  between the Lender and any Participant or subordinated debt holder
and  except  for any such  losses  caused by the  gross  negligence  or  willful
misconduct of such Indemnified  Persons, and shall reimburse the Lender and each
other  Indemnified  Person for any  expenses  including in  connection  with the
investigation of,  preparation for or defense of any actual or threatened claim,
action or proceeding  arising therefrom  (including any such costs of responding
to  discovery  requests or  subpoenas),  regardless  of whether any  Indemnified
Person is a party thereto.  Except as set forth below,  each Indemnified  Person
may select its own  counsel  with  respect to any  Losses,  in  addition  to any
Borrower's counsel, and shall be indemnified therefor hereunder.  In litigation,
or the preparation therefor, the Indemnified Persons shall be entitled to select
their own separate counsel to the extent that their  representation  by the same
counsel  would  present such  counsel  with a conflict of interest,  or would be
inappropriate  due to the actual or  potential  differing  interests  or because
there may be defenses  available to the other Persons to be  represented by such
counsel and, in addition to the foregoing indemnity,  the Borrower agrees to pay
promptly the reasonable fees and expenses of such counsel. In the event that any
Indemnified Persons are made a party to any litigation against the Borrower, the
Company or any  Guarantor  Subsidiary  relating to or arising from the Formation
Transactions,  the Borrower,  the Company or any Guarantor Subsidiary may, or if
requested by such Indemnified Persons shall,  assume primary  responsibility for
the defense thereof with counsel  reasonably  satisfactory  to such  Indemnified
Persons, subject to the right of such Indemnified Persons to separate counsel to
the extent provided in the preceding sentence. The provisions of this Section 16
shall  survive  the  termination  of  this  Agreement  and/or  repayment  of the
Obligations.

     17. GENERAL PROVISIONS.

     17.1 ACCEPTANCE.

     This Agreement  shall be binding and deemed  effective when executed by the
Borrower and Company and accepted and executed by the Lender.

     17.2 BINDING AGREEMENT.

     This  Agreement  shall  bind and  inure to the  benefit  of the  respective
successors  and  assigns of each of the  parties;  provided,  however,  that the
Borrower  and  Company  may not assign this  Agreement  or any rights  hereunder
without the Lender's prior written consent and any prohibited  assignment  shall
be absolutely  void. No consent to an assignment by the Lender shall release the
Borrower  or the  Company  from  their  obligations  to the  Lender.  Except  as
otherwise  provided herein,  the Lender may assign this Agreement and its rights
and duties  hereunder,  and the Borrower and Company  shall  execute and deliver
such documents in connection  with such  assignment as they or such assignee may
reasonably  request.  Except as otherwise  provided  herein,  Lender reserve the
right to sell, assign, transfer, negotiate or grant participations in all or any
part of, or any  interest  in their  rights and  benefits  hereunder;  provided,
however,  the Lender shall not assign all of its interest hereunder to any other
Person  without  the prior  consent  of the  Borrower,  which  consent  will not
unreasonably  be  withheld,  provided  further  that  the  Lender  shall  not be
restricted in making  partial  assignments or granting  participation  interests
hereunder.  Notwithstanding  anything to the contrary in this Agreement,  Lender
shall not assign, transfer or grant any participation in its rights and benefits
hereunder to any assignee,  transferee, or Participant which is not domiciled in
the United States, and no such participation  shall require Borrower to give any
notice,  deliver any report or  certificate,  obtain any  consent,  or otherwise
treat any  Participant  as a Lender  hereunder or pay any amount,  including any
amount under Sections 2.13 or 16 of this Agreement in excess of the amount which
would have been payable by Borrower to Lender  hereunder had such  participation
not occurred. In connection therewith, the Lender may disclose all documents and
information  which the Lender now or hereafter may have relating to the Borrower
or the Borrower's business,  but shall use all reasonable efforts to ensure that
the  recipient  of  such  information  maintains  the  confidentiality  of  such
information.

Company and the Lender.

     17.7 NO FIDUCIARY RELATIONSHIP OR JOINT VENTURE.

     No provision  herein or in any of the other Loan Documents and no course of

or joint venture between the Lender and the Borrower.

     17.8 PUBLICITY.

     Borrower hereby consents to the issuance or  dissemination by Lender to the

continue to be valid and enforceable and shall not be impaired or limited by the
execution or effectiveness of this Agreement.  Every reference  contained in the
Loan  Documents  to the Loan  Agreement  shall mean and be a  reference  to this
Agreement  and  as  the  Loan  Agreement  may  be  further  amended.  Except  as
specifically  amended by this Agreement each of the Loan Documents  shall remain
in full force and effect and are hereby ratified and confirmed.

18.      WAIVER OF JURY TRIAL.

             BORROWER  AND THE LENDER  ACKNOWLEDGE  THAT THE RIGHT TO A TRIAL BY
JURY IS A CONSTITUTIONAL  RIGHT, BUT THAT THE RIGHT MAY BE WAIVED.  THE BORROWER
AND THE LENDER EACH KNOWINGLY,  VOLUNTARILY,  IRREVOCABLY AND WITHOUT  COERCION,


                                      -28-
<PAGE>
WAIVE ALL RIGHTS TO TRIAL BY JURY OF ALL  DISPUTES  BETWEEN  THEM.  NEITHER  THE
LENDER NOR THE  BORROWER  SHALL BE DEEMED TO HAVE  GIVEN UP THIS  WAIVER OF JURY

WRITTEN  INSTRUMENT  SIGNED BY THE OTHER PARTY STATING THAT THIS WAIVER HAS BEEN
GIVEN UP.

     19. PARTNER LIABILITY.

     19.1 LIMITED RECOURSE TO COMPANY.

     Notwithstanding  anything  expressed or implied to the  contrary  contained
herein,  the  Company  shall not be  liable  hereunder  or under the  Subsidiary
Guaranty or under any legal or equitable proceeding or by virtue of any statute,
regulation or other  applicable law for (i) any payment of principal or interest
on, or any other amounts due under, any of the Loans, or (ii) to repay any other
indebtedness of Borrower or any Guarantor  Subsidiary,  provided,  however, that
nothing herein shall be construed to prevent the Lender from recovering from the
Company,  or limit the  Lender's  recourse  against  the Company for any losses,
damages or costs  (including  without  limitation,  reasonable  legal expenses),
incurred by the Lender in connection with the Company's  breach of the Company's
own covenants and agreements  herein, or in connection with the Company's fraud,
misappropriation  of funds  (whether due to the Company's  failure to contribute
Net Offering  Proceeds to the Borrowers,  as required by Section 7.17 hereof, or
its  receipt of  Distributions  from the  Borrower in  violation  of Section 6.8
hereof,  or  otherwise)  or any  misrepresentation  made by or on  behalf of the
Company hereunder or in connection with the transactions contemplated hereby.

     19.2 LIMITED RECOURSE TO PARTNERS OF BORROWER OTHER THAN THE COMPANY.

     With  respect to all partners of the  Borrower  other than the Company,  no
personal deficiency judgment or any other judgment shall be asserted or enforced
against any such partner for payment of any amount  hereunder or for  observance
or  performance  of any of the  obligations  of the Borrower  contained  herein,
except as  expressly  set forth in this  Agreement  or any  other  agreement  or
instrument or document as an  obligation of such partner in connection  herewith
(including  without limitation the Subsidiary  Guaranty),  and provided that the
foregoing  shall not affect the liability  which any of such other  partners may
have for any fraud,  misappropriation of funds or intentional  misrepresentation
made  hereunder  by or on  behalf  of the  Borrower  or in  connection  with the
transactions contemplated hereby.

     IN WITNESS  WHEREOF,  the Borrower and Company have  executed and delivered
this Agreement.

                       FIFTH AMENDMENT TO CREDIT AGREEMENT
                       -----------------------------------

     This  Fifth  Amendment  to  Credit  Agreement  is made as of the 1st day of
October,  1998 by and  among  PRIME  GROUP  REALTY,  L.P.,  a  Delaware  limited

"Company") and BANKBOSTON,  N.A., a national banking association ("BankBoston"),
PRUDENTIAL SECURITIES CREDIT CORPORATION, a Delaware corporation ("Prudential"),
the other lending institutions which are from time to time listed on Schedule 1,
(collectively,  with BankBoston and  Prudential,  the "Lenders") and BANKBOSTON,
N.A., as agent for itself and such other lending institutions (the "Agent").

     WHEREAS,  the parties hereto are parties to that certain  Credit  Agreement
dated as of November 17, 1997 as amended by First Amendment to Credit  Agreement
dated as of December 15, 1997 and by Second  Amendment to Credit Agreement dated
as of March 16,  1998,  as amended  and  restated by Third  Amendment  to Credit
Agreement  dated as of March 30,  1998 and as  amended  by Fourth  Amendment  to
Credit Agreement dated as of April 24, 1998 (the "Existing Agreement"); and

     WHEREAS,  the Borrower has requested that the Agent release the West Wacker
Drive  Property  from the lien of the Security  Documents but such release would
not be  permitted by Section 5.5 because  certain  Defaults or Events of Default
would  arise  therefrom  or from  the new  Indebtedness  to be  incurred  by the
Borrower secured by the West Wacker Drive Property; and

     WHEREAS,  the parties have agreed to amend the Existing  Agreement so as to
permit the  requested  release of the West Wacker  Drive  Property and to effect
certain other changes in the Existing Agreement.

     NOW, THEREFORE, the parties hereby agree that effective upon the
Effective  Date  hereof  (as  determined  pursuant  to  Paragraph  18 below) the
Existing Agreement is amended as follows:

     1. DECREASE IN TOTAL  COMMITMENT.  The Total Commitment is hereby decreased
to  $80,000,000  and each Lender hereby  decreases its  Commitment to the amount
shown on the revised Schedule 1.2 attached hereto.  As of the Effective Date the
Commitment Percentages of the Lenders shall be adjusted as shown on said revised
Schedule  1.2. The parties  shown on such revised  Schedule 1.2 as having a zero
Commitment  and 0% Commitment  Percentage  shall no longer be Lenders  hereunder
after the Effective Date.

     2. DEFINITIONS: Section 1.1 of the Existing Agreement is amended to provide
that the following  terms shall have the  following  meanings and, to the extent
that any of the following terms are already  defined in the Existing  Agreement,
such  definitions  shall be deemed to be amended and  restated by the  following
definitions:

amount of all cash and other investments held in the Collateral Account.

     EBITDA. The Borrower's  earnings before interest,  taxes,  depreciation and
amortization, as determined on a consolidated basis in accordance with Generally
Accepted  Accounting  Principles,  except that rental income shall be determined
based on contractual  lease terms (to the extent that the  applicable  tenant is
actually paying rent in accordance with such terms).

         Permitted  Company   Subsidiaries.   Corporations,   limited  liability
companies or other entities,  each of which is a wholly owned  Subsidiary of the
Company and whose only asset is a  partnership  interest in a  partnership  or a
membership  interest  in a  limited  liability  company  provided  that (i) such
Company Subsidiary's ownership interest in such partnership or limited liability
company does not exceed one percent (1%); (ii) the remaining 99% or more of such
partnership  or limited  liability  company is owned by the Borrower;  and (iii)
such partnership or limited  liability company owns a Property which is financed

<PAGE>
or to be financed with or through a securitized or securitizable  loan structure
and the  applicable  lender  requires  that the borrower  entity be  "bankruptcy
remote" by having a certain  percentage  of the  borrower  entity  owned by such
corporation  and,  if such  required  percentage  is less than 1%,  the  Company
Subsidiary's  ownership  interest  shall not exceed the level  required  by such
lender.

     Pro Forma  Principal  Amount.  (a) With respect to Compliance  Certificates
delivered pursuant to Section 7.4(e), the maximum  Outstanding  Principal Amount
at any time during the applicable  fiscal  quarter minus the Collateral  Account
Balance  on the  last  day of such  quarter;  (b)  with  respect  to  Compliance
Certificates  delivered  pursuant to Section 2.5,  2.9(b) or Section  11.1,  the
Outstanding  Principal  Amount after giving effect to the requested  Loan or the
issuance of the requested Letter of Credit minus the Collateral  Account Balance
on the Borrowing Date or the date of issuance of such Letter of Credit; (c) with
respect to Compliance  Certificates  delivered  pursuant to Section 5.5, Section
5.6 or Section  8.4(b),  the Outstanding  Principal  Amount minus the Collateral
Account  Balance after giving effect to any proposed sale or transfer  including

financial  statements have been provided  pursuant to Section 7.4(b),  times (b)
two, divided by (c) 0.0975. EBITDA used to compute Total Adjusted Assets will be
computed on a pro forma basis as though the assets reflected on the consolidated
balance  sheet of  Borrower  prepared  in  accordance  with  Generally  Accepted
Accounting  Principles as of the date of determination  had been owned since the
first day of the  applicable  period of two  fiscal  quarters  and as though all
assets disposed of prior to the date of determination had been disposed of prior
to the first day of the applicable period of two fiscal quarters.

     Total Liabilities. The sum of the following (without duplication):  (i) all
liabilities  of  the  Borrower  and  the  Related  Companies   consolidated  and
determined in accordance with Generally Accepted Accounting Principles excluding
the dividends  payable and accounts  payable and accrued  expenses line items as
shown on the balance  sheet  included in the  Company's  Form 10-K and Form 10-Q
statements  filed with the SEC (but not excluding the accrued  interest  payable
and accrued real estate taxes line items as shown on such balance  sheet),  (ii)
all  Indebtedness  of the Borrower and the Related  Companies  whether or not so
classified,  including,  without  limitation,  all outstanding  Loans under this

issued for the account of the  Borrower or any of the  Related  Companies.  When
compliance with Section 9.3 is being computed as of a date other than the end of
a fiscal quarter,  Total  Liabilities will be adjusted to reflect all changes in
the items described in clauses (ii) and (iii) of this  definition  since the end
of the last fiscal  quarter for which  financial  statements  have been provided
pursuant  to  Section  7.4(b)  but it  shall be  presumed  that  other  types of

     Section  5.6.  Collateral  Account.  If  Borrower  desires the release of a
Mortgaged  Property from the lien of the Security  Documents  pursuant to Sectio

deposit in the Collateral Account established pursuant to the Collateral Account
Agreement  such amount as may be required to  increase  the  Collateral  Account

under Section 9.1 or Section 9.2. In the event of any subsequent increase in the

this  Agreement  and the Borrower  delivers to the Agent a pro-forma  Compliance

contribution with respect to the Company's general  partnership  interest in the
Borrower.

     8. AMENDMENTS TO SECTION 6.19.  Section 6.19 is hereby amended and restated

Indebtedness  (and  proposed  indebtedness  for which  Borrower  has  accepted a

Mortgaged Properties.

     Section 9.2.  Minimum Debt Service  Coverage.  The Borrower will not at any
time permit the  Outstanding  Principal  Amount  (minus the  Collateral  Account

Income  for all of the  Mortgaged  Properties,  divided  by (b) Pro  Forma  Debt
Service  Charges  for the  Mortgaged  Properties  would be less than 1.5 for any
fiscal quarter of Borrower. For purposes of the foregoing, any Real Estate Asset

treated as though it were a Mortgaged  Property  for the entire  quarter and any
Real Estate Asset which is released by Agent during such fiscal quarter shall be
excluded for the entire quarter.

     Section 9.3. Total Liabilities to Total Adjusted Assets.  The Borrower will

                          Compliance Certificate under
           Credit Agreement dated as of November 17, 1997, as amended

     The undersigned, a Responsible Officer of Prime Group Realty Trust, general
partner of Prime Group Realty, L.P. (the "Borrower"), hereby certifies on behalf
of the Borrower as of the date hereof the following:

     1. NO  DEFAULTS.  I have read a copy of the  Credit  Agreement  dated as of
November  17,  1997 as amended  (the  "Credit  Agreement")  among the  Borrower,
BankBoston,  N.A., the other lending institutions party thereto, and BankBoston,
N.A., as Agent.  Terms used herein and not otherwise  defined  herein shall have
the  meanings  set forth in Section 1.1 of the Credit  Agreement.  No Default is
continuing in the  performance or observance of any of the  covenants,  terms or
provisions of the Credit  Agreement or any of the other Loan Documents.  Without
limiting  the  foregoing,  the  Borrower  has not  taken any  actions  which are
prohibited  by the  negative  covenants  set forth in  Section  8 of the  Credit
Agreement. Attached hereto as Appendix I are all relevant calculations needed to
determine  whether the Borrower is in compliance with Section 9, Section 8.3(e),
(g) and (h) and  Section 8.7 of the Credit  Agreement  as of the end of the most
recently  completed  fiscal  quarter  (except  that in the  case  of  Compliance
Certificates  delivered pursuant to Section 2.5, Section 2.9(b),  Section 2.9(d)
Section  11.1,  Section  5.5 or Section  8.4(b),  the  calculations  determining
compliance  with  Section  9.1,  Section 9.2 and  Section 9.3 are  computed on a
pro-forma  basis as of the date of such  certificate  and after giving effect to
the  proposed  transaction,  if  any,  with  respect  to  which  the  Compliance
Certificate is being  delivered),  and is in compliance  with Section 8.7 of the
Credit Agreement for the most recently completed fiscal year.

     2. NO MATERIAL  CHANGES,  ETC.  Except as  disclosed on Appendix II hereto,
since the [date of most recent financial  statements  furnished to the Agent and
the Lenders], there have occurred no materially adverse changes in the financial
condition  or business of the  Borrower as shown on or  reflected in the balance
sheet of the  Borrower  as at such date other than (a)  changes in the  ordinary
course  of  business  that have not had any  materially  adverse  effect  either
individually  or in the aggregate on the business or financial  condition of the
Borrower  and (b)  changes  resulting  from  the  making  of the  Loans  and the
transactions contemplated by the Credit Agreement.

     3. NO  MATERIALLY  ADVERSE  CONTRACTS,  ETC.  Neither the  Borrower nor the
Company is subject to any charter,  corporate, trust, partnership or other legal
restriction,  or any judgment,  decree, order, rule or regulation that has or is
expected, in the reasonable judgment of the Company's officers, in the future to
have a  Materially  Adverse  Effect.  Neither the  Borrower nor the Company is a
party to any contract or agreement  that has or is expected,  in the  reasonable
judgment of the Company's officers, to have a Materially Adverse Effect.

     Section 2.2 INTEREST; MONTHLY PAYMENTS.

     2.2.1 GENERALLY.

     (a) From the date hereof through but not including the Optional  Prepayment
Date,  Borrower shall pay interest on the outstanding  principal  balance of the
Loan at the Interest Rate.

     (b) On the date hereof, Borrower shall pay interest at the Interest Rate on
the  outstanding  principal  balance of the Loan from the Closing  Date  through
November 10, 1998.  Commencing with the Payment Date on December 11, 1998 and on
each and every Payment Date thereafter  through and including the Maturity Date,
the principal amount of the Loan and interest thereon at the Interest Rate shall
be payable in equal  monthly  installments  of  $86,544.68  (the  "Monthly  Debt
Service Payment  Amount");  such Monthly Debt Service Payment Amount being based
on the Interest  Rate and a 312-month  amortization  schedule.  The Monthly Debt
Service  Payment  Amount due on any  Payment  Date shall first be applied to the
payment of interest  accrued from the eleventh (11th) day of the month preceding
the Payment  Date through the tenth (10th) day of the month in which the Payment
Date  occurs,  notwithstanding  that the  Payment  Date may have  been  deferred
because  the  eleventh  (11th)  day of such  month is not a  Business  Day.  The
remainder of such Monthly  Debt Service  Payment  Amount shall be applied to the
reduction of the outstanding principal balance of the Note.

     (c) From and after the Optional Prepayment Date, interest on the Loan shall
accrue at the Revised Interest Rate and shall be payable as provided in Sections
2.2.2 and 2.2.3.

     2.2.2 ACCRUED  INTEREST.  From and after the Optional  Prepayment Date, all
interest  accruing  in  respect  of the  Note in  excess  of the  Interest  Rate
("Accrued Interest") shall be deferred,  be added to the Debt and, to the extent
permitted by  applicable  law,  accrue  interest at the Revised  Interest  Rate,
compounded monthly.  All Accrued Interest and interest on Accrued Interest shall
be due and payable on the Maturity Date.

     2.2.3 PROPERTY CASH FLOW  ALLOCATION  AFTER THE OPTIONAL  PREPAYMENT  DATE.
Commencing on the Optional  Prepayment  Date and continuing on each Payment Date
thereafter until the entire Debt has been paid in full, any Rents deposited into
the Cash  Collateral  Account (or  otherwise  received by  Borrower)  during the
immediately  preceding  calendar  month  shall  be  applied  as  follows  in the
following order of priority unless an Event of Default exists:

     (a)  First, to make required payments to the Tax and Insurance Escrow Fund;

     (b)  Second,  to Lender to pay the  Monthly  Debt  Service  Payment  Amount
          (plus, if applicable, interest at the Default Rate);

     (c)  Third, payments for Approved Operating Expenses;

                                      -11-

     (g)  Seventh, payments to Lender to be applied against Accrued Interest and
          interest accrued thereon; and

     (h)  Lastly, payments to Borrower of any excess amounts.

Notwithstanding anything herein to the contrary, the failure of Borrower to make
all of the payments  required under clauses (a) through (d) above in full on the
Optional  Prepayment Date and on each Payment Date thereafter shall constitute a
Default under this Agreement.  However, the failure of Borrower to pay principal
amounts  due under  clause (e) and any  Accrued  Interest or interest on Accrued
Interest on a Payment  Date as a result of  insufficient  Rents for such payment
shall not constitute a Default  hereunder.  All Accrued  Interest or interest on
Accrued Interest shall nonetheless be due and payable on the Maturity Date.

     2.2.4 DEFAULT RATE.  After the occurrence and during the  continuance of an
Event of Default,  the entire  outstanding  principal  balance of the Loan shall
bear interest at the Default Rate, and shall be payable upon demand from time to
time, to the extent  permitted by applicable  law.  Payment or acceptance of the
increased rates provided for in this  subsection is not a permitted  alternative
to timely  payment and shall not  constitute a waiver of any Default or Event of
Default or an amendment to this  Agreement or any other Loan  Document and shall
not otherwise prejudice or limit any rights or remedies of Lender.

     Section 2.3 LOAN REPAYMENT AND DEFEASANCE.

Prepayment"),  in the manner and to the extent set forth in  Sections  7.1.2 and

     (a) Subject to the terms and  conditions  set forth in this Section  2.3.3,
Borrower  may  defease  all or any  portion  of the Loan  evidenced  by the Note

          principal amount of the Note to be defeased.

     (ii) Borrower  shall pay to Lender all accrued  and unpaid  interest on the
          principal  balance  of the Note to but not  including  the  Defeasance
          Date.  If for any reason the  Defeasance  Date is not a Payment  Date,
          Borrower  shall also pay interest  that would have accrued on the Note
          to but not including the next Payment Date.

     (iii)Borrower shall pay to Lender all other sums,  not including  scheduled
          interest  or  principal  payments,  then  due  under  the  Note,  this

<PAGE>
     (vi) In the event only a portion of the Loan  evidenced  by the Note is the
          subject of the  Defeasance,  Borrower  shall  execute  and deliver all
          necessary  documents  to amend  and  restate  the Note and  issue  two
          substitute notes: one having a principal balance equal to the defeased
          portion of the original Note (the "Defeased Note") and one note having
          a principal  balance equal to the  undefeased  portion of the original
          Note (the  "Undefeased  Note").  The Defeased Note and Undefeased Note
          shall  have  identical  terms as the Note,  except  for the  principal
          balance.  A  Defeased  Note  cannot  be the  subject  of  any  further
          Defeasance.

     (vii)Borrower shall execute and deliver a security  agreement,  in form and
          substance  satisfactory  to Lender,  creating a first priority lien on
          the  Defeasance  Deposit and the U.S.  Obligations  purchased with the
          Defeasance  Deposit in accordance  with this provision of this Section
          2.3.3 (the "Security Agreement").

     (viii) Borrower  shall  deliver an opinion of counsel for  Borrower in form
          reasonably  satisfactory to Lender stating,  among other things,  that
          (A) Lender has a perfected  first  priority  security  interest in the
          Defeasance Deposit and the U.S. Obligations  delivered by Borrower and
          (B) said U.S.  Obligations  have been  validly  assigned  to the REMIC
          Trust.

     (ix) Lender shall receive  evidence in writing from the  applicable  Rating
          Agencies  to the  effect  that such  Defeasance  will not  result in a
          reduction,  withdrawal  or  requalification  of the  ratings in effect
          immediately  prior to such  Defeasance  for the  Securities  issued in
          connection with the Securitization which are then outstanding.

     (x)  If required by the  applicable  Rating  Agencies,  Borrower shall also
          deliver or cause to be  delivered  a  non-consolidation  opinion  with

          to Lender and the applicable Rating Agencies.

     (xi) Borrower shall deliver an Officer's  Certificate  certifying  that the

          instruments as Lender may reasonably request.

     (xiii)  Borrower  shall pay all  reasonable  costs and  expenses  of Lender
          incurred  in  the   Defeasance,   including  any  costs  and  expenses
          associated  with a release of Lien as  provided  in Section 2.4 hereof
          and reasonable attorney's fees and expenses.

     (b) In connection  with each  Defeasance of all or any portion of the Note,
Borrower  hereby  appoints  Lender  as its agent  and  attorney-in-fact  for the
purpose of using the  Defeasance  Deposit to purchase  U.S.  Obligations  (which
purchases, if made by Lender, shall be made by Lender on an arms-length basis at
then  prevailing  market  rates) which  provide  payments on or prior to, but as
close as possible to, all successive Payment Dates after the Defeasance Date, in
the case of a Defeasance  for the entire  outstanding  principal  balance of the
Note, or the Defeased  Note,  in the case of a Defeasance  for only a portion of
the outstanding principal balance of the Loan, as applicable (including,  on the
Optional  Prepayment Date, the outstanding  principal balance of either the Note
or the Defeased  Note),  and in amounts equal to the  scheduled  payments due on
such dates under the Note or the Defeased  Note, as applicable  (the  "Scheduled
Defeasance  Payments").  Borrower,  pursuant to the Security  Agreement or other
appropriate  document,  shall irrevocably authorize and direct that the payments
received from the U.S. Obligations may be made directly to Lender and applied to

applicable.  Any  portion  of the  Defeasance  Deposit  in excess of the  amount
necessary to purchase the U.S.  Obligations  required by this Section 2.3(a) and
satisfy  Borrower's  obligations  under  Sections  2.3 or 2.4 shall be  remitted
promptly to Borrower. Any amounts received in respect of the U.S. Obligations in
excess of the amounts necessary to make monthly payments pursuant to Section 2.2
shall be remitted promptly to Borrower.  Semi-annual payments in respect of U.S.
Obligations shall be applied to payments under the Note or the Defeased Note, as
applicable, as the same become due thereunder.

     (c) CCA shall  establish  or designate a successor  entity (the  "Successor
Borrower") and Borrower shall  transfer and assign all  obligations,  rights and
duties under and to the Note or the Defeased Note, as applicable,  together with
the pledged U.S.  Obligations to such Successor Borrower.  The obligation of CCA
to  establish  or  designate  a  Successor  Borrower  shall be  retained  by CCA


                                      -13-
<PAGE>
notwithstanding the sale or transfer of this Agreement unless such obligation is
specifically assumed by the transferee. Such Successor Borrower shall assume the
obligations under the Note or the Defeased Note, as applicable, and the Security
Agreement  and  Borrower  shall  be  relieved  of  its  obligations  thereunder,
hereunder  and  under the  other  Loan  Documents  (except  for those  which are
expressly  stated to survive).  Borrower  shall pay $1,000 to any such Successor
Borrower as  consideration  for assuming the  obligations  under the Note or the
Defeased  Note,  as  applicable,  and the  Security  Agreement.  Notwithstanding
anything in this  Agreement to the contrary,  no other  assumption  fee shall be
payable upon a transfer of the Note or the Defeased Note in accordance with this
Section 2.3.3, but Borrower shall pay all costs and expenses incurred by Lender,
including  Lender's  reasonable  attorneys'  fees  and  expenses,   incurred  in
connection therewith.

     Section 2.4 RELEASE OF  PROPERTY.  Except as set forth in this Section 2.4,
no  repayment,  prepayment or defeasance of all or any portion of the Note shall
cause,  give rise to a right to require,  or otherwise result in, the release of
the Lien of the Mortgage on the Property.

     2.4.1 RELEASE OF THE PROPERTY.

     (a) If Borrower  has elected to defease the Note in its  entirety,  and the
requirements of Section 2.3 have been satisfied,  the Property shall be released
from  the  Lien of the  Mortgage  and the  other  Loan  Documents  and the  U.S.
Obligations,  pledged  pursuant  to the  Security  Agreement,  shall be the sole
source of collateral securing the Note.

     (b) In connection  with the release of the Lien,  Borrower  shall submit to
Lender,  not less than twenty (20) days prior to the Defeasance  Date, a release
of Lien (and related Loan  Documents) for the Property (for execution by Lender)
in a form  appropriate in the State  reasonably  satisfactory  to Lender and all
other  documentation  Lender  requires to be delivered by Borrower in connection
with such release,  together with an Officer's Certificate  certifying that such
documentation  (i) is in compliance with all Legal  Requirements,  and (ii) will
effect such release in accordance with the terms of this Agreement.

     2.4.2 RELEASE ON PAYMENT IN FULL.  Lender shall,  upon the written  request
and at the  expense  of  Borrower,  upon  payment in full of all  principal  and
interest  on the Loan and all  other  amounts  due and  payable  under  the Loan
Documents in accordance with the terms thereof, release the Lien of the Mortgage
and the other Loan Documents if not theretofore released.

deposit to such account as Lender may  designate by written  notice to Borrower.
Whenever any payment  hereunder or under the Note shall be stated to be due on a
day  which is not a  Business  Day,  such  payment  shall  be made on the  first
Business Day thereafter.

     2.5.2  COMPUTATIONS.  Interest  payable  hereunder  or  under  the  Note by

under the Loan Documents is not paid by Borrower on the date on which it is due,
Borrower  shall pay to Lender upon demand an amount  equal to the lesser of five
percent (5%) of such unpaid sum or the maximum  amount  permitted by  applicable
law in order to defray the expense incurred by Lender in handling and processing
such delinquent payment and to compensate Lender for the loss of the use of such
delinquent  payment.  Any such amount  shall be secured by the  Mortgage and the
other Loan Documents.

     Section 2.6 CASH MANAGEMENT ARRANGEMENTS.

     (a) All Rents (other than security  deposits) will be transmitted  directly
into an  account  maintained  by  Borrower  but  controlled  by Lender at a bank
selected by Borrower (the "Collection Account Bank").  Borrower will establish a
separate "A" account  (the "A"  Account) and "B" Account (the "B" Account)  with
the Collection Account Bank.  Borrower shall cause all Rents to be sent directly
to the Collection  Account Bank by tenants (where  practicable) for deposit into
the "A" Account.  All other income or revenue received by Borrower or Manager in
connection  with the Property will be deposited into the "A" Account on the date


                                      -14-
<PAGE>
of receipt.  Until the earlier to occur of (i) the Optional  Prepayment  Date or
(ii) an Event of Default  (either such  occurrence,  a "Cash Trap  Event"),  the
Collection Account Bank will transfer deposits that are cleared on a daily basis
from the "A" Account to the "B" Account which shall be an account not subject to
any restrictions and under the sole control of Borrower.  Upon the occurrence of
a Cash Trap Event, the Collection  Account Bank will transfer  property receipts
that  are  cleared  on a daily  basis to the Cash  Collateral  Account  Bank for
deposit into the Cash Collateral  Account.  The duties of the Collection Account
Bank and the  application  and  disbursement  of all  funds  deposited  with the
Collection Account Bank shall be governed by the terms of this Agreement and the
Collection Account Agreement.  Any amounts so deposited into the Cash Collateral
Account  shall be  applied  and  disbursed  in  accordance  with the  terms  and
provisions of this Agreement and the Cash Collateral Account Agreement.

     (b) Lender  shall have a senior  security  interest  in the  aforementioned
accounts  and  all  subaccounts  established  thereunder  (other  than  the  "B"
Account).  The upfront and ongoing  expenses of  maintaining  such  accounts and
subaccounts, and any other accounts and reserves maintained pursuant to the Loan
Documents,  shall be the responsibility of Borrower. Funds in each account shall
be invested for the benefit of Borrower in Permitted Investments.

     (c) Anything  hereinabove in this Section to the contrary  notwithstanding,
from and after the occurrence and during the continuance of an Event of Default,
100% of all Rents and other sums deposited  into the  Collection  Account in any
month  which  remain in the Cash  Collateral  Account  shall be  applied  to the
payment of Debt Service on the Loan (including,  if applicable,  interest at the
Default Rate),  required reserves and Approved  Operating Expenses and/or to the
payment  of the  principal  amount of the Note,  in such  order as Lender  shall
determine in its sole discretion.

authority to own its  properties  and to transact the  businesses in which it is
now engaged.  Borrower is duly  qualified to do business and is in good standing
in each jurisdiction  where it is required to be so qualified in connection with
its  properties,  businesses  and  operations.  Borrower  possesses  all rights,
licenses,  permits and authorizations,  governmental or otherwise,  necessary to
entitle it to own its  properties  and to transact the businesses in which it is
now engaged  (other than those which the failure to have would not reasonably be
expected to have a material adverse effect on the Borrower,  the Property or the
Loan),  and the sole  business  of  Borrower is the  ownership,  management  and
operation of the Property.

     (b)  Proceedings.  Borrower has taken all necessary action to authorize the
execution,  delivery  and  performance  of this  Agreement  and the  other  Loan
Documents.  This Agreement and such other Loan Documents have been duly executed
and  delivered  by or on behalf of  Borrower  and  constitute  legal,  valid and
binding obligations of Borrower  enforceable against Borrower in accordance with
their respective terms, subject to applicable bankruptcy, insolvency and similar
laws affecting rights of creditors generally, and subject, as to enforceability,
to general principles of equity (regardless of whether  enforcement is sought in
a proceeding in equity or at law).

     (c) No Conflicts. The execution, delivery and performance of this Agreement
and the other Loan  Documents by Borrower  will not conflict with or result in a
breach of any of the terms or provisions of, or constitute a default  under,  or
result in the creation or imposition of any lien,  charge or encumbrance  (other
than  pursuant  to the Loan  Documents)  upon any of the  property  or assets of
Borrower pursuant to the terms of any indenture,  mortgage,  deed of trust, loan
agreement,  partnership  agreement  or other  agreement or  instrument  to which
Borrower is a party or by which  Borrower's  property or assets is subject,  nor
will such action result in any violation of the provisions of any statute or any
order,  rule or  regulation of any court or  governmental  agency or body having
jurisdiction  over Borrower or any of its  properties or assets (other than such
actions  described  herein  which  would not  reasonably  be  expected to have a
material  adverse effect on the Borrower,  the Property,  or the Loan),  and any
consent,  approval,  authorization,  order,  registration or qualification of or
with any court or any such regulatory  authority or other governmental agency or
body required for the  execution,  delivery and  performance  by any Borrower of
this  Agreement  or any other Loan  Documents  has been  obtained and is in full
force and effect.

     (d)  Litigation.  There are no actions,  suits or  proceedings at law or in
equity by or before any  Governmental  Authority  or other agency now pending or
threatened against or affecting Borrower or the Property,  which actions,  suits
or proceedings, if determined against Borrower or the Property, might materially
adversely affect the condition  (financial or otherwise) or business of Borrower
or the condition or ownership of the Property.

     (e)  Agreements.  Borrower is not a party to any agreement or instrument or
subject to any  restriction  which would  reasonably  be expected to  materially
adversely affect Borrower or the Property, or Borrower's business, properties or
assets,  operations  or condition,  financial or  otherwise.  Borrower is not in
default in any material respect in the performance, observance or fulfillment of
any of the  obligations,  covenants or  conditions  contained  in any  Permitted
Encumbrance  or any other  agreement or  instrument to which it is a party or by
which it or the Property is bound.

     (f)  Title.  Borrower  has  good  and  insurable  title  in fee to the real
property  comprising part of the Property,  and good title to the balance of the
Property,   free  and  clear  of  all  Liens  whatsoever  except  the  Permitted
Encumbrances,  such other Liens as are permitted  pursuant to the Loan Documents
and the Liens created by the Loan Documents. The Mortgage when properly recorded
in the appropriate records,  together with any Uniform Commercial Code financing


                                      -17-
<PAGE>
statements  required  to be filed in  connection  therewith,  will  create (i) a
valid, perfected first priority lien on the Property,  subject only to Permitted
Encumbrances  and the Liens  created by the Loan  Documents  and (ii)  perfected
security  interests  in and to, and  perfected  collateral  assignments  of, all
personalty  (including the Leases), all in accordance with the terms thereof, in
each case  subject only to any  applicable  Permitted  Encumbrances,  such other
Liens as are permitted  pursuant to the Loan  Documents and the Liens created or
permitted by the Loan  Documents.  The Permitted  Encumbrances do not materially
adversely  affect the value or use of the  Property,  or  Borrower's  ability to
repay the Loan.  There are no claims for  payment for work,  labor or  materials
affecting  the  Property  which are or may  become a lien  prior to, or of equal
priority with, the Liens created by the Loan Documents.

of a petition by it under any state or federal  bankruptcy or insolvency laws or
the  liquidation  of all or a major  portion  of its  assets  or  property,  and
Borrower  has no knowledge  of any Person  contemplating  the filing of any such
petition against it.

     (h) Full and Accurate Disclosure.  No statement of fact made by Borrower in
this  Agreement  or in any of the  other  Loan  Documents  contains  any  untrue
statement of a material  fact or omits to state any material  fact  necessary to
make statements contained herein or therein not misleading. There is no material
fact  presently  known to Borrower  which has not been disclosed to Lender which
adversely affects,  nor as far as Borrower can foresee,  might adversely affect,
the Property or the business,  operations or condition  (financial or otherwise)
of Borrower.

     (i) No Plan Assets.  Borrower is not an "employee benefit plan," as defined
in Section 3(3) of ERISA, subject to Title I of ERISA, and none of the assets of
Borrower  constitutes or will constitute "plan assets" of one or more such plans
within the meaning of 29 C.F.R. Section 2510.3-101.

     (j)  Compliance.  To the best of  Borrower's  knowledge,  Borrower  and the
Property and the use thereof comply in all material respects with all applicable
Legal Requirements, including building and zoning ordinances and codes. Borrower
has not  received  notice  of any  default  or  violation  of any  order,  writ,
injunction,  decree or demand of any  Governmental  Authority,  the violation of
which is likely to  materially  adversely  affect the  condition  (financial  or
otherwise)  or  business  of  Borrower.  There has not been and  shall  never be
committed by Borrower or, to Borrower's  actual  knowledge,  any other person in
occupancy  of or involved  with the  operation or use of the Property any act or
omission  affording the federal  government or any state or local government the
right of  forfeiture  as against the  Property or any part thereof or any monies
paid in performance of Borrower's  obligations  under any of the Loan Documents.
Borrower hereby covenants and agrees not to commit or permit,  and shall use its
commercially  reasonable  efforts to  prevent  any other  person or entity  from
committing, any act or omission affording such right of forfeiture.

     (k)  Contracts.  Except as set forth on  Schedule  1, there are no material
contracts  affecting the Property which are not terminable on one month's notice
or less without cause and without  penalty or premium.  All contracts  affecting
the Property  (except for the  Management  Agreement)  have been entered into at
arms-length  in the ordinary  course of  Borrower's  business and all  contracts
affecting the Property  (including  the  Management  Agreement)  provide for the
payment of fees in amounts and upon terms comparable to existing market rates.

     (l) Financial Information.  All financial data, including the statements of
cash flow and income and operating  expense,  that have been delivered to Lender
by Borrower in respect of the Property (i) are true, complete and correct in all
material  respects,  (ii)  accurately  represent the financial  condition of the
Property as of the date of such  reports and (iii) to the extent  prepared by an
independent  certified public  accounting firm, have been prepared in accordance
with  GAAP  consistently  applied  throughout  the  periods  covered,  except as
disclosed  therein.  Borrower has no  contingent  liabilities,  liabilities  for
taxes,  unusual  forward or long-term  commitments  or unrealized or anticipated
losses  from  any  unfavorable  commitments  that  are  known  to  Borrower  and
reasonably  likely to have a  materially  adverse  effect on the Property or the
operation  thereof,  except  as  referred  to or  reflected  in  said  financial
statements.  Since  the date of such  financial  statements,  there  has been no
materially adverse change in the financial condition,  operations or business of
Borrower from that set forth in said financial statements.

     (m)  Condemnation.  No Condemnation or other  proceeding has been commenced
or, to Borrower's  best knowledge,  is  contemplated  with respect to all or any
portion of the Property or for the  relocation of roadways  providing  access to
the Property.

                                      -18-

     (n) Federal Reserve  Regulations.  No part of the proceeds of the Loan will
be used for the purpose of purchasing or acquiring any "margin stock" within the
meaning of Regulation U of the Board of Governors of the Federal  Reserve System
or for any other purpose which would be  inconsistent  with such Regulation U or
any other Regulations of such Board of Governors, or for any purposes prohibited
by Legal  Requirements  or by the terms and  conditions of this Agreement or the
other Loan Documents.

     (o)  Utilities  and Public  Access.  The  Property  has rights of access to
public  ways and is served  by  water,  sewer,  sanitary  sewer and storm  drain
facilities  adequate to service the Property for its  respective  intended uses.
All public utilities necessary to the full use and enjoyment of the Property are
located in the public right-of-way  abutting the Property.  To Borrower's actual
knowledge,  all roads  necessary  for the use of the Property for their  current
respective purposes have been completed and dedicated to public use and accepted
by all Governmental Authorities.

     (p) Not a Foreign  Person.  Borrower is not a "foreign  person"  within the
meaning ofss.1445(f)(3) of the Code.

     (q)  Separate  Lots.  The  Property is comprised of one (1) or more parcels
which  constitutes  a separate tax lot and does not  constitute a portion of any
other tax lot not a part of the Property.

     (r) Assessments.  To the best of Borrower's knowledge, there are no pending
or proposed  special or other  assessments for public  improvements or otherwise
affecting  the  Property,  nor are there any  contemplated  improvements  to the
Property that may result in such special or other assessments.

     (s)  Enforceability.  The Loan  Documents  are not  subject to any right of
rescission,  set-off, counterclaim or defense by Borrower, including the defense
of usury,  nor would the exercise of any of the terms of the Loan Documents,  or
the exercise of any right thereunder,  render the Loan Documents  unenforceable,
and Borrower has not asserted any right of rescission,  set-off, counterclaim or
defense with respect thereto.

     (t) No Prior  Assignment.  There are no  assignments  of the  Leases or any
portion  of the Rents due and  payable or to become  due and  payable  which are
presently outstanding.

     (u) Insurance.  Borrower has obtained and has delivered to Lender insurance
certificates reflecting the insurance coverages,  amounts and other requirements
set forth in this Agreement.

     (v) Use of Property. The Property is used exclusively as an office building
and other appurtenant and related uses.

     (w)  Certificate  of  Occupancy;  Licenses.  All  material  certifications,
permits,  licenses and  approvals,  including  certificates  of  completion  and
occupancy permits and any applicable liquor licenses required for the legal use,
occupancy and operation of the Property  (collectively,  the  "Licenses"),  have
been obtained and are in full force and effect. Borrower shall keep and maintain
all licenses necessary for the operation of the Property.  The use being made of
the Property is in conformity with the  certificate of occupancy  issued for the
Property.

     (x) Flood Zone. To Borrower's actual knowledge, none of the Improvements on
the  Property  are  located  in an  area  identified  by the  Federal  Emergency
Management Agency as an area having special flood hazards.

     (y) Physical  Condition.  To  Borrower's  actual  knowledge,  the Property,
including all buildings,  improvements,  parking  facilities,  sidewalks,  storm
drainage  systems,  roofs,  plumbing  systems,  HVAC  systems,  fire  protection
systems, electrical systems, equipment,  elevators,  exterior sidings and doors,
landscaping,  irrigation  systems  and all  structural  components,  are in good
condition,  order  and  repair in all  material  respects;  and  there  exist no
structural or other material defects or damages in the Property,  whether latent
or otherwise.  Borrower has not received  notice from any  insurance  company or
bonding  company of any defects or  inadequacies  in the  Property,  or any part
thereof,  which would adversely affect the insurability of the same or cause the
imposition of extraordinary premiums or charges thereon or of any termination or
threatened termination of any policy of insurance or bond.

     (z)  Appraised  Value.  To  Borrower's   actual   knowledge,   all  of  the
improvements  which were  included in  determining  the  appraised  value of the
Property lie wholly within the boundaries and building  restriction lines of the


                                      -19-
<PAGE>
Property,  and  no  improvements  on  adjoining  properties  encroach  upon  the
Property, and no easements or other encumbrances upon the Property encroach upon
any of the  improvements,  so as to  affect  the value or  marketability  of the
Property except those which are insured against by title insurance.

     (aa) Leases. Attached hereto as Schedule 2 is a rent roll (the "Rent Roll")
for the  Property.  The Rent Roll is true,  correct and complete in all material
respects with respect to the subject matter thereof.  The only Leases  affecting
the  Property  are those  reflected in the Rent Roll.  To  Borrower's  knowledge
following inquiry as a duly diligent property purchaser,  except as set forth in
Schedule  1: (i) each Lease is in full force and  effect;  (ii) except for those
Leases with terms that have not yet commenced, the tenants under the Leases have
accepted  possession of and are in occupancy of all of their respective  demised
premises  (unless  such  demised  premises  or  portions   thereof,   have  been
subleased),  have  commenced the payment of rent under such Leases and there are
no offsets,  claims or defenses to the enforcement thereof;  (iii) all rents due
and payable under the Leases have been paid and no portion thereof has been paid
for any period  more than thirty  (30) days in  advance;  (iv) the rent  payable
under  each Lease is the amount set forth in the Rent Roll and there is no claim
or basis for a claim by the tenant thereunder for an adjustment to the rent; (v)
no tenant has made any claim against the landlord under the Leases which remains
outstanding  and there are no  defaults  on the part of the  landlord  under any
Lease and no event has occurred  which,  with the giving of notice or passage of
time,  or both,  would  constitute  such  default;  and (vi) there is no present
material default by any tenant under any Lease.  None of the Leases contains any
option to purchase or right of first  refusal to  purchase  the  Property or any
part thereof. The Leases have not been assigned or pledged except to Lender, and
no  other  person  whatsoever  has  any  interest  therein  except  the  tenants
thereunder.

     (bb) Survey. To Borrower's  actual  knowledge,  the survey for the Property
delivered to Lender in connection  with this  Agreement does not fail to reflect
any material matter affecting the Property or the title thereto.

     (cc)  Filing  and  Recording  Taxes.  All  transfer  taxes,   deed  stamps,
intangible taxes or other amounts in the nature of transfer taxes required to be
paid by any Person under  applicable Legal  Requirements  currently in effect in
connection  with the  transfer of the Property to Borrower  have been paid.  All
mortgage, mortgage recording, stamp, intangible or other similar tax required to
be paid by any Person under applicable Legal Requirements currently in effect in
connection  with the execution,  delivery,  recordation,  filing,  registration,
perfection or enforcement of any of the Loan Documents,  including the Mortgage,
have  been  paid  and,  under  current  Legal  Requirements,   the  Mortgage  is
enforceable  against  Borrower in accordance with its respective terms by Lender
(or any subsequent holder thereof), except as such enforceability may be limited
by  insolvency,  bankruptcy,  moratorium  or  other  laws  affecting  creditor's
remedies in general and principles of equity.

     (dd)  Single-Purpose.  Borrower  hereby  represents  and  warrants  to, and
covenants  with,  Lender that,  as of the date hereof and until such time as the
Debt shall be paid in full:

     (i)  Borrower  does not and will not own any asset or  property  other than
          (A) the Property and (B) incidental  personal  property  necessary for
          the ownership or operation of the Property.

     (ii) Borrower  will not engage in any  business  other than the  ownership,
          management  and  operation  of the  Property  and will in all material
          respects  conduct and operate its business as presently  conducted and
          operated.

     (iii)Borrower  will not enter into any  contract or  agreement  with any of
          its affiliates or constituent  parties,  any guarantor (a "Guarantor")
          of the Debt or any part thereof or any  affiliate  of any  constituent
          party  or  Guarantor,  except  upon  terms  and  conditions  that  are
          intrinsically  fair and  substantially  similar to those that would be
          available on an  arms-length  basis with third  parties other than any
          such party.

     (iv) Borrower  has  not  incurred,   and  Borrower  will  not  incur,   any
          indebtedness,  secured or unsecured,  direct or indirect,  absolute or
          contingent  (including  guaranteeing any  obligation),  other than the
          Permitted  Indebtedness.  Except  as  set  forth  in  the  immediately
          preceding sentence, no indebtedness other than the Debt may be secured
          (subordinate or pari passu) by the Property.



                                      -20-
<PAGE>
     (v)  Borrower  has not made and will not make any loans or  advances to any
          third  party  (including  any  affiliate  or  constituent  party,  any
          Guarantor or any  affiliate of any  constituent  party or  Guarantor),
          other than  immaterial  advances for tenant  improvements  pursuant to
          Leases executed in accordance with this Agreement.

     (vi) Borrower  is and  will  remain  solvent  and will  pay its  debts  and
          liabilities  (including  employment  and overhead  expenses)  from its
          assets as the same shall become due.

     (vii)Borrower  has  done or  caused  to be  done  and  will  do all  things
          necessary  to observe  corporate,  partnership,  or limited  liability
          company formalities, as the case may be, and preserve its existence.

     (viii) Borrower  will not permit any  constituent  party or  Guarantor  to,
          amend,  modify  or  otherwise  change  the  partnership   certificate,
          partnership  agreement,  articles of incorporation and bylaws,  trust,
          operating agreement or other  organizational  documents of Borrower or
          such constituent  party or Guarantor in a manner which would adversely
          affect Borrower's existence as a single purpose entity.

     (ix) Borrower  will maintain  books and records and bank accounts  separate
          from those of its  affiliates and any  constituent  party and Borrower
          will file its own tax returns.

     (x)  Borrower  will be, and at all times will hold itself out to the public
          as,  a legal  entity  separate  and  distinct  from any  other  entity
          (including any affiliate,  any constituent party, any Guarantor or any
          affiliate  of any  constituent  party  or  Guarantor),  shall  conduct
          business  in its own name and  shall  maintain  and  utilize  separate
          stationery, invoices and checks.

     (xi) Borrower will  maintain  adequate  capital for the normal  obligations
          reasonably  foreseeable in a business of its size and character and in
          light of its contemplated business operations.

     (xii)Neither  Borrower nor any constituent  party will seek the dissolution
          or winding up, in whole or in part, of Borrower.

     (xiii) Borrower will not commingle its funds and other assets with those of
          any affiliate or constituent party, any Guarantor, or any affiliate of
          any constituent party or Guarantor, or any other person.

     (xiv)Borrower  has and will  maintain  its assets in such a manner  that it
          will not be costly or  difficult to  segregate,  ascertain or identify
          its  individual  assets  from those of any  affiliate  or  constituent
          party,  any Guarantor,  or any affiliate of any  constituent  party or
          Guarantor, or any other person.

     (xv) Borrower does not and will not hold itself out to be  responsible  for
          the debts or obligations of any other person.

     (xvi)Borrower  shall at all times have one member (the "SPE Member") who is
          a "single  purpose  entity" and shall at all times comply with each of
          the  representations,  warranties,  and  covenants  contained  in this
          Section 4.1 as if such  representation,  warranty or covenant was made
          directly by such SPE Member.

     (xvii) The  charter of the SPE Member  shall at all times have at least one
          duly  appointed  member of its  board of  directors  (an  "Independent
          Director")  reasonably  satisfactory to Lender who shall not have been
          at the time of such individual's appointment, and may not have been at
          any time  during the  preceding  five (5) years (i) a member of, or an
          officer or employee of,  Borrower or any of its members,  subsidiaries
          or  Affiliates  (except  as an  Independent  Director  on any of their
          boards of  directors),  (ii) a customer or supplier  who derives  more
          than  ten  percent  (10%)  of  its  purchases  or  revenues  from  its
          activities  with  Borrower  or  any of its  members,  subsidiaries  or
          Affiliates  (except as an Independent  Director on any of their boards
          of  directors),  (iii) a person or other entity  controlling  any such
          member,  supplier or customer or (iv) a member of the immediate family
          of any such member, officer, employee,  supplier or customer or of any
          other director of the SPE Member.  As used herein,  the term "control"
          means the possession,  directly or indirectly,  of the power to direct
          or cause the direction of the  management  and policies of a person or
          entity, whether through ownership of voting securities, by contract or
          otherwise.

                                      -21-
<PAGE>
     (xviii) The board of  directors of the SPE Member shall not take any action
          which, under the terms of any certificate of incorporation,  bylaws or
          any voting trust agreement with respect to any common stock,  requires
          the vote of the board of  directors  of the SPE  Member  unless at the
          time of such  action  there  shall be at least  one  member  who is an
          Independent Director.

     (xix)Borrower shall conduct its business so that the assumptions  made with
          respect to Borrower in that  certain  opinion  letter  dated as of the
          Closing Date  delivered by Borrower's  counsel in connection  with the
          Loan shall be true and correct in all respects.

     (ee) Investment Company Act. Borrower is not (i) an "investment company" or
a company  "controlled"  by an "investment  company,"  within the meaning of the
Investment  Company  Act of 1940,  as  amended;  (ii) a "holding  company"  or a
"subsidiary  company"  of a  "holding  company"  or an  "affiliate"  of either a
"holding  company" or a  "subsidiary  company"  within the meaning of the Public
Utility Holding  Company Act of 1935, as amended;  or (iii) subject to any other
federal or state law or  regulation  which  purports to restrict or regulate its
ability to borrow money.

     (ff)  Fraudulent  Transfer.  Borrower  has not entered into the Loan or any
Loan Document with the actual intent to hinder,  delay, or defraud any creditor,
and  Borrower  has  received  reasonably  equivalent  value in exchange  for its
obligations  under  the  Loan  Documents.  Giving  effect  to  the  transactions
contemplated by the Loan Documents, the fair saleable value of Borrower's assets
exceeds and will,  immediately  following the execution and delivery of the Loan
Documents,   exceed  Borrower's  total  liabilities,   including   subordinated,
unliquidated,  disputed or contingent  liabilities.  The fair saleable  value of
Borrower's assets is and will,  immediately following the execution and delivery
of  the  Loan  Documents,  be  greater  than  Borrower's  probable  liabilities,
including the maximum amount of its contingent  liabilities or its debts as such
debts become  absolute and matured.  Borrower's  assets do not and,  immediately
following the execution and delivery of the Loan Documents will not,  constitute
unreasonably small capital to carry out its business as conducted or as proposed
to be conducted. Borrower does not intend to, and does not believe that it will,
incur  debts  and  liabilities   (including  contingent  liabilities  and  other
commitments)  beyond its ability to pay such debts as they mature  (taking  into
account the timing and amounts to be payable on or in respect of  obligations of
Borrower).

     (gg) Management  Agreement.  The Management  Agreement is in full force and
effect and there is no default,  breach or violation existing  thereunder by any
party  thereto and no event has  occurred  (other than  payments due but not yet
delinquent)  that,  with the  passage of time or the giving of notice,  or both,
would constitute a default, breach or violation by any party thereunder. Neither
the  execution  and  delivery  of the  Loan  Documents,  Borrower's  performance
thereunder, the recordation of the Mortgage, nor the exercise of any remedies by
Lender, will adversely affect Borrower's rights under the Management Agreement.

     Section 4.2 SURVIVAL OF  REPRESENTATIONS.  Borrower  agrees that all of the
representations  and  warranties  of  Borrower  set  forth  in  Section  4.1 and
elsewhere in this Agreement and in the other Loan Documents shall survive for so
long as any amount  remains  owing to Lender under this  Agreement or any of the
other Loan Documents by Borrower. All representations, warranties, covenants and
agreements  made in this  Agreement  or in the other Loan  Documents by Borrower
shall  be  deemed  to have  been  relied  upon  by  Lender  notwithstanding  any
investigation heretofore or hereafter made by Lender or on its behalf.

V.   AFFIRMATIVE COVENANTS

     Section 5.1 BORROWER COVENANTS.  From the date hereof and until payment and
performance  in full of all  obligations of Borrower under the Loan Documents or
the earlier release of the Lien of the Mortgage (and all related obligations) in
accordance  with the  terms of this  Agreement  and the  other  Loan  Documents,
Borrower hereby covenants and agrees with Lender that:

     (a) Existence;  Compliance  with Legal  Requirements;  Insurance.  Borrower
shall do or cause to be done all things necessary to preserve, renew and keep in
full force and effect its existence,  rights,  licenses,  permits and franchises
and  comply  with all  Legal  Requirements  applicable  to it and the  Property.
Borrower  shall at all times  maintain,  preserve and protect all franchises and
trade names and preserve all the remainder of its property used or useful in the
conduct of its business  and shall keep the  Property in good working  order and
repair,  and  from  time to time  make,  or cause  to be  made,  all  reasonably
necessary repairs, renewals, replacements, betterments and improvements thereto,
all as more fully provided in the Mortgage.

                                      -22-
<PAGE>
     (b) Taxes and Other Charges. Borrower shall pay all Taxes and Other Charges
now or hereafter  levied or assessed or imposed against the Property or any part
thereof  as the same  become  due and  payable,  other  than  those  which it is
protesting  in good  faith by  appropriate  proceedings  diligently  pursued  in
accordance  with this  Section.  Borrower  will  deliver to Lender  receipts for
payment  or other  evidence  satisfactory  to  Lender  that the  Taxes and Other
Charges have been so paid or are not then  delinquent  no later than thirty (30)
days prior to the date on which the Taxes and/or Other Charges  would  otherwise
be delinquent if not paid (provided,  however,  that Borrower is not required to
furnish  such  receipts for payment of Taxes in the event that such Taxes are to
be paid by Lender pursuant to Section 7.3 hereof if Borrower furnishes a request
by such date for a disbursement from the Tax and Insurance Escrow Fund and there
are sufficient funds therein to make the payment). Borrower shall not suffer and
when due shall  cause to be paid and  discharged  any lien or charge  whatsoever
which may be or become a lien or charge  against the Property  (other than those
liens or charges  which  Borrower  is  protesting  in good faith by  appropriate
proceedings,  diligently  pursued),  and  when  due  shall  pay for all  utility
services  provided  to the  Property.  After  prior  written  notice to  Lender,
Borrower,  at its own  expense,  may contest by  appropriate  legal  proceeding,
promptly  initiated  and  conducted  in good faith and with due  diligence,  the
amount  or  validity  or  application  in whole or in part of any Taxes or Other
Charges,  provided  that (i) no  Default or Event of Default  has  occurred  and
remains uncured,  (ii) such proceeding shall suspend the collection of the Taxes
or Other Charges from the  Property,  (iii) such  proceeding  shall be permitted
under and be conducted in accordance with the provisions of any other instrument
to which Borrower is subject and shall not constitute a default thereunder, (iv)
neither the Property nor any part thereof or interest  therein will be in danger
of being sold, forfeited,  terminated, canceled or lost, (v) Borrower shall have
furnished  such  security  as may be required  in the  proceeding,  or as may be
reasonably requested by Lender, to insure the payment of any such Taxes or Other
Charges,  together  with all interest and  penalties  thereon and (vi)  Borrower
shall promptly upon final determination thereof pay the amount of any such Taxes
or Other Charges,  together with all costs,  interest and penalties which may be
payable in  connection  therewith  subject to payment  pursuant to Section  7.3.
Lender may,  following prior written notice to Borrower,  pay over any such cash
deposit or part thereof held by Lender to the claimant  entitled  thereto at any
time when,  in the  judgment  of Lender,  the  entitlement  of such  claimant is
established.

     (c) Litigation.  Borrower shall give prompt written notice to Lender of any
litigation or governmental  proceedings  pending or threatened  against Borrower
which might  materially  adversely  affect  Borrower's  condition  (financial or
otherwise) or business or the Property.

     (d) Premises.  Borrower shall permit agents,  representatives and employees
of Lender to inspect the Property or any part thereof at  reasonable  hours upon
reasonable advance notice.

     (e)  Notice  of  Default.  Borrower  shall  promptly  advise  Lender of any
material adverse change in Borrower's condition,  financial or otherwise,  or of
the  occurrence  of any  Default  or Event of  Default  of  which  Borrower  has
knowledge.

     (f) Cooperate in Legal  Proceedings.  Borrower shall  cooperate  fully with
Lender  with  respect  to any  proceedings  before  any  court,  board  or other
Governmental  Authority  which may in any way  materially  adversely  affect the
rights of Lender  hereunder  or any rights  obtained by Lender  under any of the
other Loan  Documents  and,  in  connection  therewith,  permit  Lender,  at its
election, to participate in any such proceedings.

     (g) Perform Loan Documents. Borrower shall observe, perform and satisfy all
the terms,  provisions,  covenants and conditions of, and shall pay when due all
costs,  fees and  expenses  to the  extent  required  under  the Loan  Documents
executed and delivered by Borrower.

     (h) Insurance  Benefits.  Borrower shall cooperate with Lender in obtaining
for Lender the benefits of any Insurance  Proceeds lawfully or equitably payable
in  accordance  with Section 7.1 hereof in  connection  with the  Property,  and
Lender shall be reimbursed  for any expenses  incurred in  connection  therewith
(including attorneys' fees and disbursements, and the expense of an appraisal on
behalf of Lender in case of a fire or other  casualty  affecting the Property or
any part thereof) out of such Insurance Proceeds.

     (i)  Further  Assurances.  Borrower  shall,  at  Borrower's  sole  cost and
expense:



                                      -23-
<PAGE>
          (A) furnish to Lender all instruments,  documents,  boundary  surveys,
footing  or  foundation   surveys,   certificates,   plans  and  specifications,
appraisals, title and other insurance reports and agreements, and each and every
other document,  certificate,  agreement and instrument required to be furnished
by it pursuant to the terms of the Loan  Documents  or  reasonably  requested by
Lender in connection therewith;

          (B)  execute  and  deliver  to  Lender  such  documents,  instruments,
certificates,  assignments and other writings,  and do such other acts necessary
or desirable,  to evidence,  preserve  and/or protect the collateral at any time
securing or  intended to secure its  obligations  under the Loan  Documents,  as
Lender may reasonably require, so long as Borrower's liability is not materially
increased thereby; and

          (C) do and execute all and such further  lawful and  reasonable  acts,
conveyances and assurances for the better and more effective carrying out of the
intents and purposes of this Agreement and the other Loan  Documents,  as Lender
shall reasonably  require from time to time, so long as Borrower's  liability is
not materially increased thereby.

     (j)  Supplemental  Mortgage  Affidavits.  If at any time Lender  reasonably
determines,  based on  applicable  law,  that Lender is not being  afforded  the
maximum  amount of security  available from the Property as a direct or indirect
result of  applicable  taxes not having been paid with respect to the  Property,
Borrower  agrees that Borrower will execute,  acknowledge and deliver to Lender,
immediately upon Lender's request, supplemental affidavits increasing the amount
of the Debt  attributable to the Property to the amount of the Debt and Borrower
shall, on demand, pay any additional taxes.

     (k) Financial Reporting.

          (i)  Borrower  will  keep and  maintain  or will  cause to be kept and
maintained on a Fiscal Year basis,  in accordance with GAAP or another method of
preparation approved by Lender,  proper and accurate books, records and accounts
reflecting all of the financial  affairs of Borrower and all items of income and
expense in connection  with the operation of the Property and in connection with
any services, equipment or furnishings provided in connection with the operation
of the  Property,  whether  such income or expense be realized by Borrower or by
any other Person  whatsoever,  excepting  lessees  unrelated to and unaffiliated
with  Borrower  who have leased from  Borrower  portions of the Property for the
purpose of occupying the same.  Lender shall have the right from time to time at
all times during normal  business hours upon  reasonable  notice to examine such
books,  records  and  accounts  at  the  office  of  Borrower  or  other  Person
maintaining such books, records and accounts and to make such copies or extracts
thereof as Lender shall desire.  After the occurrence and during the continuance
of an Event of Default,  Borrower  shall pay any costs and expenses  incurred by
Lender to examine Borrower's accounting records with respect to the Property, as
Lender  shall  determine to be necessary or  appropriate  in the  protection  of
Lender's interest.

          (ii) Borrower will furnish to Lender  annually,  (A) within forty (40)
days  following  the end of each Fiscal Year of  Borrower,  unaudited  financial

accountant  reasonably acceptable to Lender in accordance with GAAP covering the
Property  for  such  Fiscal  Year  and (z)  financial  statements  of  Borrower,
unaudited but certified by an independent certified public accountant reasonably
acceptable to Lender,  containing  balance  sheets and  statements of profit and
loss for  Borrower  and the  Property  in such  detail as Lender may  reasonably
request.  Such statements shall set forth the financial condition and the income
and  expenses  for the  Property for the  immediately  preceding  calendar  year
including statements of annual net operating income. Borrower's annual financial
statements shall be accompanied by an Officer's Certificate  certifying that, to
the best of such  officer's  knowledge,  each such  annual  financial  statement
presents fairly the financial condition of the Property and has been prepared in
accordance with GAAP.  Together with  Borrower's  annual  financial  statements,
Borrower shall furnish to Lender an Officer's  Certificate  certifying as of the
date thereof  whether,  to the best of its  knowledge,  there exists an event or
circumstance  which  constitutes  a Default or Event of  Default  under the Loan
Documents  executed and  delivered by Borrower,  and if such Default or Event of
Default exists,  the nature  thereof,  the period of time it has existed and the
action then being taken to remedy the same.

          (i) After  request  by  Lender,  Borrower  shall  within ten (10) days
furnish Lender with a statement, duly acknowledged and certified,  setting forth
(A) the unpaid  principal amount of the Note, (B) the Interest Rate of the Note,
(C) the date  installments of interest and/or  principal were last paid, (D) any
offsets or defenses  to the  payment of the Debt,  if any and (E) that the Note,
this Agreement,  the Mortgage and the other Loan Documents are valid,  legal and
binding  obligations  and  have  not  been  modified  or  if  modified,   giving
particulars of such modification.

          (ii) After request by Lender (but no more  frequently than once in any
year),  Borrower  shall within ten (10) days furnish  Lender with a  certificate
reaffirming all  representations and warranties of Borrower set forth herein and
in the other Loan Documents as of the date requested by Lender or, to the extent
of any  changes to any such  representations  and  warranties,  so stating  such
changes.

other  modification  of any Loan  Document  executed  and  delivered by Borrower
without the prior written consent of Lender.

     (r) Annual  Budget.  Borrower  shall  prepare  and  submit (or shall  cause
Manager to prepare  and  submit) to Lender by December 1 of each year during the
Term, a proposed pro forma  budget for the  Property for the  succeeding  fiscal
year  commencing  January 1 and ending  December 31 (the "Annual  Budget")  and,
promptly after  preparation  thereof,  any  subsequent  revisions to such Annual
Budget.  After the  occurrence of a Cash Trap Event,  the Annual Budget shall be
subject to Lender's  approval which approval shall not be unreasonably  withheld
or  delayed.  Lender's  failure  to  approve or  disapprove  any  Annual  Budget
requiring  Lender's  approval  within  thirty (30) days after  Lender's  receipt
thereof  shall be deemed to constitute  Lender's  approval  thereof.  The Annual
Budget shall consist of (i) an operating expense budget (the "Operating Budget")
showing, on a month-by-month  basis, in reasonable detail, each line item of the
Borrower's anticipated income and Operating Expenses (on a cash modified basis),

Governmental  Authorities  in all  relevant  jurisdictions  indicating  the good

joint assessment of the Property (i) with any other real property constituting a
tax lot  separate  from the  Property  and (ii) with any portion of the Property
which may be deemed to  constitute  personal  property,  or any other  procedure
whereby the lien of any taxes which may be levied against such personal property
shall be assessed or levied or charged to the Property.

     (u) Leasing  Matters.  Borrower shall not,  without  Lender's prior written
consent,  enter  into,  modify,  amend or renew any Lease (x) for 10,000 or more
square feet while an Event of Default is not occurring or (y) for any size while
an Event of Default is  continuing.  Any Lease for less than 10,000  square feet
that is entered into, modified,  amended or renewed during a period of time when


                                      -26-
<PAGE>
no Event of Default  exists shall be deemed  approved by Lender  (such Lease,  a
"Deemed  Approved  Lease").  If Lender  does not approve or  disapprove  a Lease
(other than a Deemed  Approved  Lease) within ten (10) Business Days of Lender's
receipt of such Lease and all information  relating thereto reasonably requested
by Lender,  such Lease shall be deemed  approved.  Upon request,  Borrower shall
furnish  Lender with executed  copies of all Leases.  All renewals of Leases and
all proposed  Leases shall  provide for rental rates that are at or greater than
existing local market rates for space at properties similar to the Property. All
proposed Leases shall be on commercially  reasonable terms and shall not contain
any terms which would materially adversely affect Lender's rights under the Loan
Documents.  All Leases shall provide that they are  subordinate  to the Mortgage
encumbering  the Property  and that the lessee  agrees to attorn to Lender if it
succeeds to the interest of Borrower in the Property. Borrower (i) shall observe
and perform the obligations imposed upon the lessor under the Leases, other than
immaterial  obligations  the failure of which to perform is not likely to have a
material adverse effect on the Property or the applicable Lease(s);  (ii) shall,
in the exercise of its prudent business judgment,  enforce the terms,  covenants
and conditions contained in the Leases upon the part of the lessee thereunder to
be observed or performed; (iii) shall not collect any of the rents more than one
(1) month in advance (other than security deposits);  (iv) shall not execute any
other  assignment  of lessor's  interest  in the Leases or the Rents  (except as
contemplated by the Loan Documents);  (v) shall not alter,  modify or change the
terms of the Leases in a manner  inconsistent  within the provisions of the Loan
Documents;  and (vi) shall execute and deliver at the request of Lender all such
further assurances,  confirmations and assignments in connection with the Leases
as Lender shall from time to time reasonably require.

pursuant the Management Agreement. Borrower shall:

          (i)  promptly   perform  and/or  observe  all  of  the  covenants  and
agreements  required to be  performed  and  observed by it under the  Management
Agreement  and do all things  necessary to preserve and to keep  unimpaired  its
material rights thereunder;

          (ii)  promptly  notify  Lender of any  default  under  the  Management
Agreement of which it is aware;

          (iii)  promptly,  upon Lender's  request,  deliver to Lender a copy of
each financial  statement,  business plan, capital  expenditures plan,  property
improvement plan and any other notice,  report and estimate received by it under
the Management Agreement; and

          (iv) promptly  enforce the  performance  and  observance of all of the
covenants and agreements required to be performed and/or observed by the Manager

following:

     (a)  Operation of Property.  Borrower  shall not,  without  Lender's  prior

with or consolidate into another Person.

     (d) Change In Business.  Borrower shall not enter into any line of business
other than the ownership  and  operation of the  Property,  or make any material
change  in  the  scope  or  nature  of  its  business  objectives,  purposes  or
operations, or undertake or participate in activities other than the continuance
of its present business.

     (e) Debt  Cancellation.  Borrower shall not cancel or otherwise  forgive or
release any claim or debt owed to Borrower  by any Person,  except for  adequate
consideration  and  in  the  ordinary  course  of  Borrower's  business  in  its
reasonable judgment.

     (f) Affiliate  Transactions.  Borrower  shall not enter into, or be a party
to, any  transaction  with an  Affiliate  of  Borrower  or any of the members of
Borrower  except in the ordinary course of business and on terms which are fully
disclosed  to Lender in advance  and are no less  favorable  to Borrower or such
Affiliate than would be obtained in a comparable arms-length transaction with an
unrelated third party.

     (g)  Zoning.   Borrower  shall  not  initiate  or  consent  to  any  zoning
reclassification  of any  portion of any of the  Property  or seek any  variance
under any existing  zoning  ordinance or use or permit the use of any portion of
any of the  Property  in any  manner  that could  result in such use  becoming a
non-conforming  use under any zoning  ordinance or any other applicable land use
law, rule or regulation, without the prior consent of Lender.

     (h) Assets.  Borrower shall not purchase or own any real  properties  other
than the Property.

     (i) Debt.  Borrower shall not create,  incur or assume any debt  (including

benefit of such Person, Borrower or the Property.

     (j)  Transfers.  Borrower shall not,  without the prior written  consent of
Lender,  suffer  or permit  the  sale,  assignment  or  transfer  (collectively,
"Transfer")  of (i) all or any  part of the  Property  (except  pursuant  to any
Lease)  other  than in  connection  with a  Special  Transfer,  (ii) any  direct
interest in  Borrower or (iii) any direct or indirect  interest in any member of
Borrower  other than (A) the  issuance or transfer of  beneficial  interests  in
Prime Group Realty Trust, a Maryland real estate  investment  trust,  so long as
such  issuance or transfer does not result in a change in Control of Prime Group
Realty  Trust and so long as such  issuance  or  transfer  does not  affect  the
non-consolidation  opinion  delivered  by  Borrower,  and  (B) the  issuance  or
transfer of limited  partner  interests  in Prime Group  Realty L.P., a Delaware
limited  partnership,  or a  conversion  of a one  percent  general  partnership
interest owned  beneficially  by The Nardi Group,  L.L.C.  in Prime Group Realty
L.P. into a limited partnership  interest in Prime Group Realty L.P., so long as
such  issuance or transfer does not result in a change in Control of Prime Group
Realty  L.P.  and so long as such  issuance  or  transfer  does not  affect  the
non-consolidation  opinion  delivered  by  Borrower;   provided,  however,  that
Borrower may grant the easements  and other rights in the Property  specifically
permitted under Section 8(f) of the Mortgage. No Transfer consented to by Lender
pursuant to clause (ii) or (iii) above shall be  permitted  unless  Lender shall
have received (a) evidence in writing from the applicable Rating Agencies to the
effect that such a Transfer  will not result in a  qualification,  withdrawal or
downgrading of the ratings in effect  immediately prior to such Transfer for the
Securities  issued  in  connection  with  the  Securitization   which  are  then
outstanding and (b) a non-consolidation  opinion satisfactory to Lender from the
transferee's  counsel.  On or  before  the  completion  of  any  such  permitted
Transfer,  Borrower  will pay all  reasonable  expenses  of Lender  incurred  in
connection therewith. Notwithstanding anything to the contrary contained in this
clause (j),  holders of  interests  in Borrower  (or holders of interests in any
entity  directly or  indirectly  holding an interest in Borrower) as of the date
hereof (the "Interest  Holders") shall have the right to transfer their interest
in  Borrower  (or any entity  directly  or  indirectly  holding an  interest  in
Borrower) to another  Person who is not an Interest  Holder,  including  without
limitation  immediate  family  members  for estate  planning  purposes,  without
Lender's consent; provided, however, that:

          (i) after  taking into  account any prior  transfers  pursuant to this
sentence,  whether to the proposed transferee or otherwise, no such transfer (or
series of transfers) shall result in (A) the proposed transferee,  together with


                                      -28-
<PAGE>
all members of his/her immediate family or any affiliates thereof, owning in the
aggregate (directly,  indirectly or beneficially) more than 20% of the interests
in  Borrower  (or any entity  directly  or  indirectly  holding an  interest  in
Borrower) or (B) a transfer in the  aggregate of more than 20% of the  interests
in Borrower as of the date hereof;

          (ii) no such transfer of interest  shall result in a change of control
of Borrower or the day-to-day operations of the Property;

          (iii) Borrower shall give Lender notice of such transfer together with
copies of all  instruments  effecting  such transfer not less than ten (10) days
prior to the date of such transfer;

          (iv) no Event of Default has occurred and remains uncured; and

          (v) the legal and financial  structure of Borrower after such transfer
and its members  and the single  purpose  nature and  bankruptcy  remoteness  of
Borrower  and its  shareholders,  partners or members  satisfies  Lender's  then
current  applicable  underwriting  criteria and requirements,  including without
limitation  the  requirement  at  the  request  of  Lender  to  deliver  written
confirmations from the Rating Agencies that such transfer or series of transfers
will  not  result  in a  qualification,  downgrade  or  withdrawal  of the  then
applicable ratings.

For  purposes of this clause (j),  (A) a change of control of Borrower  shall be
deemed to have occurred if there is any change in the identity of the individual
or entities or group of individuals or entities who have the right, by virtue of
any  partnership  agreement,  articles  of  incorporation,  bylaws,  articles of
organization, operating agreement or any other agreement, with or without taking
any  formative  action,  to cause  Borrower  to take some  action or to prevent,
restrict or impede  Borrower  from taking some  action  which,  in either  case,
Borrower  could take or could  refrain from taking were it not for the rights of
such individuals;  and (B) an "immediate family member" shall mean a spouse or a
child of any Interest Holder.

          (iii) Rental loss and/or business interruption  insurance in an amount
equal to the greater of (A) the estimated  gross revenues from the operations of
the  Property  for the next  succeeding  eighteen  (18) month  period or (B) the
projected  operating  expenses  (including Debt Service) for the maintenance and
operation of the Property for the next  succeeding  eighteen  (18) month period.
The amount of such  insurance  shall be  increased  from time to time during the
Term as and when the Rents  increase or the  estimate  of (or the actual)  gross
revenue, as may be applicable, increases.

          (iv)  Insurance  against  loss or damage from (A) leakage of sprinkler
systems and (B) explosion of steam boilers,  air  conditioning  equipment,  high
pressure piping, machinery and equipment,  pressure vessels or similar apparatus
now or hereafter  installed in any of the  Improvements  (without  exclusion for
explosions), in an amount at least equal to $2,000,000 for the Property.

          (v) Worker's  compensation  insurance with respect to any employees of
Borrower, as required by any governmental authority or legal requirement.

          (vi) During any period of repair or restoration,  builder's "all risk"

of the  Improvements  to agreed  limits)  as  Lender  may  request,  in form and
substance acceptable to Lender.

          (vii)  Coverage  to  compensate  for the  cost of  demolition  and the
increased cost of  construction  for the Property in an amount  satisfactory  to
Lender.

          (viii)  Such other  insurance  as may from time to time be  reasonably
required by Lender in order to protect its interests.

     (c) All policies of insurance (the "Policies") required pursuant to Section
7.1.1(b) shall be issued by companies reasonably approved by Lender and licensed
to do  business  in the State,  with a claims  paying  ability  rating of "A" or
better by  Standard & Poor's  Ratings  Group;  (ii)  shall  name  Lender and its
successors  and/or assigns as their interest may appear as the mortgagee;  (iii)
shall  contain a  Non-Contributory  Standard  Lender  Clause and a Lender's Loss
Payable Endorsement, or their equivalents,  naming Lender as the person to which
all payments made by such insurance  company shall be paid; (iv) shall contain a
waiver of subrogation  against  Lender;  (v) shall be maintained  throughout the

Borrower,  Lender nor any other party shall be a co-insurer  under said Policies
and that Lender shall receive at least thirty (30) days prior written  notice of
any modification,  reduction or cancellation of any of the Policies;  and (viii)
shall be  satisfactory  in form and substance to Lender and shall be approved by
Lender  as to  amounts,  form,  risk  coverage,  deductibles,  loss  payees  and
insureds.  Borrower  shall pay the premiums for such  Policies  (the  "Insurance
Premiums")  as the same  become  due and  payable  and shall  furnish  to Lender
evidence of the renewal of each of the Policies with receipts for the payment of
the Insurance Premiums or other evidence of such payment reasonably satisfactory
to Lender  (provided,  however,  that  Borrower is not  required to furnish such
evidence  of  payment  to Lender if such  Insurance  Premiums  have been paid by
Lender  pursuant  to Section 7.3  hereof).  If  Borrower  does not furnish  such
evidence  and  receipts  at least ten (10) days prior to the  expiration  of any
expiring Policy, then Lender may procure, but shall not be obligated to procure,
such insurance and pay the Insurance Premiums  therefor,  and Borrower agrees to
reimburse  Lender for the cost of such  Insurance  Premiums  promptly on demand.
Within  thirty (30) days after  request by Lender,  Borrower  shall  obtain such
increases in the amounts of coverage  required  hereunder  as may be  reasonably
requested  by Lender,  taking into  consideration  changes in the value of money
over time,  changes in  liability  laws,  and  changes  in prudent  customs  and
practices.

     (d) If any Property is damaged or  destroyed,  in whole or in part, by fire
or other  casualty (an "Insured  Casualty"),  Borrower  shall give prompt notice
thereof to Lender.  Following the occurrence of an Insured Casualty,  unless the
Loan is repaid in full,  Borrower  shall  promptly  proceed to restore,  repair,
replace  or  rebuild  the  Property  to  be of  at  least  equal  value  and  of
substantially the same character as prior to such damage or destruction,  all to
be effected in  accordance  with Legal  Requirements.  The expenses  incurred by
Lender in the adjustment and collection of insurance  proceeds shall become part
of the Debt and be secured  hereby and shall be reimbursed by Borrower to Lender
upon demand.

     7.1.2 CASUALTY AND APPLICATION OF PROCEEDS.

     (a) In  case  of  loss  or  damages  covered  by any of the  Policies,  the
following provisions shall apply:

          (i) If an Insured  Casualty  does not exceed  $200,000,  Borrower  may
settle and adjust any claim  without the consent of Lender;  provided  that such
adjustment  is  carried  out in a  competent  and timely  manner.  In such case,
Borrower is hereby  authorized  to collect  and  receipt for any such  insurance
proceeds.

          (ii) If an Insured Casualty shall equal or exceed $200,000, Lender may
settle and adjust any claim  without the consent of Borrower  and agree with the
insurance  company or  companies  on the amount to be paid on the loss,  and the
proceeds of any such policy  shall be due and payable  solely to Lender and held
in escrow by Lender in accordance with the terms hereof.

     (b) In the event of an Insured  Casualty  where the loss is in an aggregate
amount less than $2,000,000,  and if, in the reasonable  judgment of Lender, the
Property  can be  restored  within  six (6)  months  and  prior to the  Optional
Prepayment  Date to an economic  unit not less valuable and not less useful than
the same was prior to the  Insured  Casualty,  and after such  restoration  will
adequately  secure the Debt,  then, if no Default or Event of Default shall have
occurred and be then continuing,  the proceeds of insurance (after reimbursement
of any expenses  incurred by Lender) shall be applied to reimburse  Borrower for
the cost of restoring,  repairing,  replacing or rebuilding the Property or part
thereof subject to the Insured Casualty (the  "Restoration"),  in the manner set
forth herein.  Borrower  hereby  covenants and agrees to commence and diligently
prosecute such Restoration;  provided that (i) Borrower shall pay all costs (and
if required by Lender,  Borrower  shall deposit the total thereof with Lender in
advance) of such  Restoration  in excess of the net proceeds of  insurance  made
available  pursuant to the terms hereof;  (ii) the Restoration  shall be done in
compliance  with all Legal  Requirements;  and (iii) Lender shall have  received
evidence  reasonably   satisfactory  to  it  that,  during  the  period  of  the
Restoration,  the sum of (A) income  derived from the  Property,  as  reasonably
determined  by Lender,  plus (B)  proceeds  of rent loss  insurance  or business
interruption  insurance,  if any, to be paid will equal or exceed the sum of (I)
expenses in  connection  with the  operation  of the  Property and (II) the Debt
Service under the Loan.

     (c) Except as provided above, the proceeds of insurance  collected upon any
Insured  Casualty  shall,  at the  option of Lender in its sole  discretion,  be
applied to the payment of the Debt or applied to reimburse Borrower for the cost
of any  Restoration,  in the manner set forth below. Any such application to the
Debt shall be without any  prepayment  consideration  except that if an Event of
Default has occurred and is continuing  at the time the  insurance  proceeds are
received,  then Borrower  shall pay to Lender an additional  amount equal to the
Yield  Maintenance  Premium,  if any, that would be required under Section 2.3.3
hereof if a Defeasance Deposit was to be made by Borrower.  Any such application
to the Debt shall be applied to those  payments of principal  and interest  last
due under  the Note but shall not  postpone  or reduce  any  payments  otherwise
required pursuant to the Note other than such last due payments.

     (d) If Borrower is entitled to reimbursement out of insurance proceeds held
by   Lender,   such   proceeds   shall  be   deposited   by   Lender   into  the
Casualty/Condemnation Subaccount (as described in the Cash Collateral Agreement)
and disbursed from time to time from the  Casualty/Condemnation  Subaccount upon
Lender being  furnished  with (i) evidence  satisfactory  to it of the estimated
cost of  completion  of the  Restoration,  (ii)  funds or, at  Lender's  option,
assurances  satisfactory to Lender that such funds are available,  sufficient in
addition to the proceeds of  insurance  to complete  the  proposed  Restoration,
(iii)  such  architect's  certificates,  waivers  of  lien,  contractor's  sworn
statements, title insurance endorsements,  bonds, plats of survey and such other
evidences of cost,  payment and performance as Lender may reasonably require and
approve and (iv) all plans and specifications  for such Restoration,  such plans
and  specifications  to be approved by Lender prior to commencement of any work.
In addition,  no payment made prior to the final  completion of the  Restoration
shall exceed ninety  percent (90%) of the value of the work  performed from time
to time;  funds other than  proceeds of insurance  shall be  disbursed  prior to
disbursement of such proceeds; and at all times, the undisbursed balance of such
proceeds  remaining in the hands of Lender,  together  with funds  deposited for
that purpose or  irrevocably  committed to the  satisfaction  of Lender by or on
behalf  of  Borrower  for that  purpose,  shall be at  least  sufficient  in the
reasonable  judgment  of  Lender  to pay  for  the  cost  of  completion  of the
Restoration,  free and clear of all liens or claims for lien.  Any surplus which
may remain out of insurance  proceeds held by Lender after payment of such costs
of Restoration shall be paid to Borrower.

                                      -31-

     7.1.3 CONDEMNATION.

     (a) Borrower  shall  promptly give Lender  written  notice of the actual or
threatened  commencement  of  any  condemnation  or  eminent  domain  proceeding
affecting the Property (a "Condemnation")  and shall deliver to Lender copies of
any and all papers served in connection  with such  Condemnation.  Following the
occurrence  of a  Condemnation,  Borrower,  regardless  of  whether  an Award is
available,  shall promptly  proceed to restore,  repair,  replace or rebuild the
Property  to  the  extent  practicable  to be of at  least  equal  value  and of
substantially  the  same  character  as prior  to such  Condemnation,  all to be
effected in accordance with Legal Requirements.

     (b) Lender is hereby irrevocably appointed as Borrower's  attorney-in-fact,
coupled with an interest,  with exclusive  power to collect,  receive and retain
any award or payment in respect of a  Condemnation  (an "Award") and to make any
compromise or settlement in connection  with such  Condemnation,  subject to the
provisions of this Section.  Notwithstanding  any  Condemnation by any public or
quasi-public   authority   (including  any  transfer  made  in  lieu  of  or  in
anticipation of such a Condemnation), Borrower shall continue to pay the Debt at
the time and in the manner  provided for in the Note, in this  Agreement and the
other Loan  Documents  and the Debt  shall not be  reduced  unless and until any
Award  shall have been  actually  received  and applied by Lender to expenses of
collecting  the Award and to discharge of the Debt.  Lender shall not be limited
to the  interest  paid on the  Award by the  condemning  authority  but shall be
entitled to receive out of the Award  interest at the rate or rates  provided in
the Note.  Borrower shall cause any Award that is payable to Borrower to be paid
directly to Lender.

     (c) In the event of any  Condemnation  where  the Award is in an  aggregate
amount less than $2,000,000,  and if, in the reasonable  judgment of Lender, the
Property  can be  restored  within  six (6)  months  and  prior to the  Optional
Prepayment  Date to an economic  unit not less valuable and not less useful than
the  same  was  prior to the  Condemnation,  and  after  such  restoration  will
adequately  secure the Debt,  then, if no Default or Event of Default shall have
occurred and be then continuing,  the proceeds of the Award (after reimbursement
of any expenses  incurred by Lender) shall be applied to reimburse  Borrower for
the cost of restoring,  repairing,  replacing or rebuilding the Property or part
thereof subject to Condemnation (the  "Condemnation  Restoration") in the manner
set forth below. Borrower hereby covenants and agrees to commence and diligently
to prosecute such Condemnation Restoration; provided that (i) Borrower shall pay
all costs (and if required by Lender,  Borrower  shall deposit the total thereof
with Lender in advance) of such Condemnation  Restoration in excess of the Award
made available pursuant to the terms hereof;  (ii) the Condemnation  Restoration
shall be done in compliance with all Legal Requirements;  and (iii) Lender shall
have received evidence reasonably  satisfactory to it that, during the period of
the Condemnation  Restoration,  the sum of (A) income derived from the Property,
as reasonably  determined by Lender, plus (B) proceeds of rent loss insurance or
business interruption insurance, if any, to be paid will equal or exceed the sum
of (I) expenses in  connection  with the  operation of the Property and (II) the
Debt Service under the Loan.

     (d) Except as provided  above,  the Award  collected upon any  Condemnation
shall, at the option of Lender in its sole discretion, be applied to the payment
of the Debt or applied to reimburse  Borrower  for the cost of the  Condemnation
Restoration  in the manner set forth  below.  Any such  application  to the Debt
shall be without any prepayment consideration except that if an Event of Default
has occurred and is continuing at the time the Award is received,  then Borrower
shall pay to Lender an additional amount equal to the Yield Maintenance Premium,
if any,  that would be  required  under  Section  2.3.3  hereof if a  Defeasance
Deposit was to be made by Borrower.  Any such  application  to the Debt shall be
applied to those  payments of principal and interest last due under the Note but
shall not postpone or reduce any  payments  otherwise  required  pursuant to the
Note  other  than such  last due  payments.  If the  Property  is sold,  through
foreclosure or otherwise,  prior to the receipt by Lender of such Award,  Lender
shall have the right,  whether or not a deficiency judgment on the Note shall be
recoverable or shall have been sought,  recovered or denied, to receive all or a
portion of said Award sufficient to pay the Debt.

     (e) In the event  Borrower is entitled  to  reimbursement  out of the Award
received by Lender,  such  proceeds  shall be  disbursed  from time to time upon
Lender being  furnished  with (i) evidence  satisfactory  to it of the estimated
cost of completion of the Condemnation  Restoration,  (ii) funds or, at Lender's
option,  assurances  satisfactory  to  Lender  that such  funds  are  available,
sufficient in addition to the proceeds of the Award to complete the Condemnation
Restoration, (iii) such architect's certificates,  waivers of lien, contractor's
sworn statements, title insurance endorsements,  bonds, plats of survey and such


                                      -32-
<PAGE>
other  evidences  of costs,  payment and  performance  as Lender may  reasonably
require and approve; and (iv) all plans and specifications for such Condemnation
Restoration,  such plans and  specifications  to be approved by Lender  prior to
commencement of work. In addition, no payment made prior to the final completion
of the  restoration,  repair,  replacement  and  rebuilding  shall exceed ninety
percent (90%) of the value of the work  performed  from time to time;  (y) funds
other than  proceeds of the Award shall be disbursed  prior to  disbursement  of
such proceeds;  and (z) at all times,  the undisbursed  balance of such proceeds
remaining in the hands of Lender, together with funds deposited for that purpose
or  irrevocably  committed  to the  satisfaction  of  Lender  by or on behalf of
Borrower  for  that  purpose,  shall be at least  sufficient  in the  reasonable
judgment  of  Lender  to pay for the  costs of  completion  of the  Condemnation
Restoration  free and clear of all liens or claims for lien.  Any surplus  which
may remain out of the Award  received by Lender  after  payment of such costs of
restoration,  repair,  replacement or rebuilding shall, in the sole and absolute
discretion of Lender, be retained by Lender and applied to payment of the Debt.

     Section 7.2 REQUIRED REPAIR; REQUIRED REPAIR FUNDS.

Property  set forth on  Schedule  3 annexed  hereto  (the  "Required  Repairs").
Borrower shall  complete each of the Required  Repairs on or before the deadline
for same set forth on Schedule 3. On the Closing  Date,  Borrower  shall deposit
with Lender the amount set forth on  Schedule 3 hereto to perform  the  Required

Lender's  name  at a  financial  institution  selected  by  Lender  in its  sole
discretion and shall be invested in Permitted Investments.

     7.2.2 GRANT OF SECURITY  INTEREST.  Borrower  hereby  pledges,  assigns and
grants a security interest to Lender, as security for payment of all sums due in
respect  of the Loan and the  performance  of all other  terms,  conditions  and
covenants of the Loan Documents and this Agreement on Borrower's part to be paid
and  performed,  all of  Borrower's  right,  title  and  interest  in and to the
Required  Repair  Fund and the  Required  Repair  Account.  Borrower  shall not,
without obtaining the prior written consent of Lender, further pledge, assign or
grant any security  interest in the Required  Repair Fund or the Required Repair
Account or permit any lien or encumbrance to attach  thereto,  or any levy to be
made thereon, or any UCC-l Financing  Statements,  except those naming Lender as
the secured party, to be filed with respect thereto.

     7.2.3 RELEASE OF REQUIRED  REPAIR FUNDS.  Lender shall disburse to Borrower
all Required  Repair Funds in the Required  Repair Account upon  satisfaction by
Borrower  of each of the  following  conditions:  (a)  Borrower  shall  submit a
written  request  for  payment to Lender at least  thirty (30) days prior to the
date on which  Borrower  requests such payment be made (except in the case of an
emergency repair which requires immediate attention, in which event Borrower may
submit such payment request within ten (10) days),  (b) on the date such request
is  received by Lender and on the date such  payment is to be made,  no Event of
Default  shall  exist and remain  uncured,  (c) Lender  shall have  received  an
Officer's  Certificate from Borrower certifying that all Required Repairs at the
Property for which  disbursement has been requested have been completed (i) in a
good and  workmanlike  manner and (ii) in accordance  with all applicable  Legal
Requirements,  such  certificate  to be  accompanied  by a copy of each license,
permit or other approval  required by any Governmental  Authority for the use or
occupancy  of  the  Property,  (d)  Lender  shall  have  received  an  Officer's
Certificate from Borrower (i) identifying each Person that supplied materials or
labor in connection with the Required  Repairs for which  disbursement  has been
requested  (ii)  stating  that each such Person has been paid in full or will be
paid in full with the funds  disbursed,  such certificate to be accompanied by a
copy of appropriate  lien waivers or other evidence of payment  satisfactory  to
Lender, (e) at Lender's option, a title search for the Property  indicating that
the  Property  is free  from  all  liens,  claims  and  other  encumbrances  not
previously  approved  by Lender and (f) Lender  shall have  received  such other
evidence as Lender shall  reasonably  request  that the Required  Repairs at the
Property have been  completed and paid for or will be paid for with the proceeds
of such  disbursement.  Lender  shall be required to make only one  disbursement
from the Required Repair Account during a month and such  disbursement  shall be
made only upon  satisfaction of each condition  contained in this Section 7.2.3.
Upon  completion of all Required  Repairs in  accordance  with the terms hereof,
Lender shall  disburse to Borrower  any amounts  then  remaining in the Required
Repair Account.

     7.2.4 FAILURE TO PERFORM REQUIRED REPAIRS. It shall be a Default under this
Agreement if (a) Borrower does not complete the Required Repairs at the Property
by the  required  deadline  for each  repair as set forth on  Schedule  3 or (b)
Borrower does not satisfy each condition contained in Section 7.2.3 hereof. Upon
the occurrence of an Event of Default,  Lender, at its option,  may withdraw all
Required Repair Funds from the Required Repair Account and Lender may apply such
funds either to  completion  of the  Required  Repairs at the Property or toward
payment  of the Debt in such  order,  proportion  and  priority  as  Lender  may
determine in its sole discretion.  Lender's right to withdraw and apply Required
Repair Funds shall be in addition to all other  rights and remedies  provided to
Lender under this Agreement and the other Loan Documents.

     Section 7.3 TAX AND INSURANCE ESCROW FUND.

     7.3.1 TAX AND INSURANCE  ESCROW FUND.  Borrower  shall pay to Lender (a) on
each Payment Date, (i)  one-twelfth  (1/12) of the Taxes that Lender  reasonably
estimates will be payable during the next ensuing twelve (12) months in order to
accumulate  with Lender  sufficient  funds to pay all such Taxes at least thirty
(30) days prior to their respective due dates and (ii) one-twelfth (1/12) of the
Insurance  Premiums that Lender estimates will be payable for the renewal of the
coverage  afforded  by the  Policies  upon the  expiration  thereof  in order to
accumulate with Lender  sufficient  funds to pay all such Insurance  Premiums at
least  thirty (30) days prior to the  expiration  of the Policies and (b) on the
Closing Date, an amount which, when combined with the monthly deposits described
in (a) above,  shall be sufficient to pay the next  installment of Taxes and the
next  required  payment of  Insurance  Premiums on the due date  therefor  (said
amounts in (a) and (b) above  hereinafter  called the "Tax and Insurance  Escrow
Fund").  The Tax and  Insurance  Escrow  Fund,  and the  payments of interest or
principal or both,  payable  pursuant to the Note,  shall be added  together and
shall be paid as an aggregate  sum by Borrower to Lender.  Lender will apply the
Tax and  Insurance  Escrow  Fund to  payments  of Taxes and  Insurance  Premiums
required  to be made by  Borrower  pursuant  to Section 5.1 hereof and under the
Mortgage,  or to  reimburse  Borrower  for such  amounts  upon  presentation  of
evidence  of  payment  and  an  Officer's  Certificate  in  form  and  substance
satisfactory to Lender;  subject,  however, to Borrower's right to contest Taxes
in accordance with Section 5.1(b) hereof.  In making any payment relating to the
Tax and Insurance Escrow Fund, Lender may do so according to any bill, statement
or estimate procured from the appropriate  public office (with respect to Taxes)
or insurer or agent (with respect to Insurance  Premiums),  without inquiry into
the  accuracy of such bill,  statement  or estimate or into the  validity of any
tax, assessment,  sale,  forfeiture,  tax lien or title or claim thereof. If the
amount of the Tax and  Insurance  Escrow  Fund shall  exceed the amounts due for
Taxes and Insurance Premiums pursuant to Section 5.1 hereof, Lender shall return
any excess to Borrower or credit such excess against future  payments to be made
to the Tax and Insurance Escrow Fund. In allocating such excess, Lender may deal
with the Person shown on the records of Lender to be the owner of the  Property.
If at any time Lender  determines that the Tax and Insurance  Escrow Fund is not
or will not be  sufficient  to pay the  items  set  forth in (a) and (b)  above,
Lender shall notify Borrower of such  determination  and Borrower shall increase
its monthly payments to Lender by the amount that Lender reasonably estimates is
sufficient  to make up the  deficiency  at  least  thirty  (30)  days  prior  to
delinquency of the Taxes and/or expiration of the Policies, as the case may be.

     7.3.2 GRANT OF SECURITY  INTEREST.  Borrower  hereby  pledges,  assigns and
grants a security  interest to Lender,  as security  for payment of all sums due
under the Loan and the performance of all other terms, conditions and provisions
of the Loan  Documents  and this  Agreement  on  Borrower's  part to be paid and
performed,  of all  Borrower's  right,  title and interest in and to the Tax and
Insurance Escrow Fund.  Borrower shall not, without  obtaining the prior written
consent of Lender,  further pledge, assign or grant any security interest in the
Tax and  Insurance  Escrow  Fund,  or permit any lien or  encumbrance  to attach
thereto,  or any levy to be made  thereon,  or any UCC-1  Financing  Statements,
except  those  naming  Lender as the  secured  party,  to be filed with  respect
thereto.

     7.3.3 APPLICATION OF TAX AND INSURANCE ESCROW FUND. Upon the occurrence and
during the  continuance  of an Event of Default,  Lender may apply any sums then
present in the Tax and  Insurance  Escrow Fund to the  payment of the  following
items in any order in its sole  discretion:  (a) Taxes  and Other  Charges;  (b)
Insurance  Premiums;  (c) interest on the unpaid principal  balance of the Note;
(d) amortization of the unpaid  principal  balance of the Note; or (e) all other
sums payable  pursuant to this Agreement and the other Loan  Documents.  The Tax
and  Insurance  Escrow  Fund  shall  not  constitute  a  trust  fund  and may be
commingled  with  other  monies  held by Lender.  Sums in the Tax and  Insurance
Escrow  Fund  shall  be held by  Lender  in an  account  in  Lender's  name at a
financial  institution  selected by Lender in its sole  discretion  and shall be


                                      -34-
<PAGE>
invested in Permitted  Investments.  Earnings or interest, if any, thereon shall
be retained as part of such funds and applied in  accordance  with this  Section
7.3.  Lender shall not be liable for any loss sustained on the investment of any
funds constituting the Tax and Insurance Escrow Fund.

     Section 7.4 CAPITAL RESERVE FUND.

     7.4.1 CAPITAL  RESERVE FUND.  Borrower  shall pay to Lender on each Payment
Date an  amount  equal  to  one-twelfth  (1/12th)  of the  product  obtained  by
multiplying  $0.55 by the aggregate  amount of square feet of rentable  space in
the Property  (said  amounts  hereinafter  called the "Capital  Reserve  Fund").
Lender  will apply the  Capital  Reserve  Fund to payment  of  Approved  Capital
Expenses pursuant to the terms hereof; provided, however, if the Loan shall have
been  accelerated or if there is an Event of Default which is  continuing,  then
Lender may credit such Capital  Reserve  Fund against the Debt in such  priority
and proportions as Lender in its sole and absolute discretion shall deem proper.
If the amount of the  Capital  Reserve  Fund shall  exceed the  amounts  due for
Approved  Capital  Expenses  pursuant to the terms hereof,  Lender shall, in its
discretion,  return any excess to Borrower  or, if future  Capital  Reserve Fund
payments are then  required,  credit such excess  against such future  payments;
provided,  however,  if the Loan shall have been  accelerated  or if there is an
Event of Default which is continuing, then Lender may credit such excess against
the Debt in such  priority  and  proportions  as Lender in its sole and absolute
discretion shall deem proper.

     7.4.2 GRANT OF SECURITY  INTEREST.  Borrower  hereby pledges and assigns to
Lender,  and grants to Lender a security interest in all Borrower's right, title
and interest in and to the Capital  Reserve Fund, as security for payment of all
sums due under the Loan and the  performance of all other terms,  conditions and
provisions  of the Loan  Documents and this  Agreement on Borrower's  part to be
paid and  performed.  Borrower  shall not,  without  obtaining the prior written
consent of Lender,  further pledge, assign or grant any security interest in the
Capital  Reserve Fund, or permit any lien or encumbrance to attach  thereto,  or
any levy to be made thereon,  or any UCC-1  Financing  Statements,  except those
naming  Lender as the secured  party,  to be filed with  respect  thereto.  This
Agreement  is,  among  other  things,  intended  by the parties to be a security
agreement for purposes of the Illinois Uniform Commercial Code.

         Tenant  extends the term of the Tribune Lease such that the  expiration
         date of the  Tribune  Lease is no  earlier  than March 31,  2008,  then

         Prime Group Guaranty (as defined below);

                  (iii)  Borrower  shall not be  required  to make any  Rollover
         Payments if, as determined by Lender as of January 1, 2001,  the Leases
         that expire  during a single  calendar year at no time  represent  more
         than twenty  percent (20%) of the gross  leasable area of the Property;
         and

                  (iv)  Borrower  shall  not be  required  to make any  Rollover
         Payments if Borrower  delivers to Lender, on or before January 1, 2001,
         an irrevocable  letter of credit in the amount of $643,160.00 in a form
         and issued by a bank reasonably  acceptable to Lender, and Lender shall
         have the right to draw upon and apply the proceeds  from such letter of
         credit at the times and in the manner  provided in this Section 7.5 for
         application of funds deposited in the Rollover Reserve Fund.

         Realty,  L.P.  unconditionally  guarantees the payment of all costs and
         expenses, up to a maximum amount of $643,160.00, incurred in connection
         with Approved Leasing Expenses.  Lender shall have the right to enforce
         the Prime Group  Guaranty and apply the  proceeds  from the Prime Group
         Guaranty at the times and in the manner  provided  in this  Section 7.5
         for application of funds deposited in the Rollover Reserve Fund.

     (b) Lender will apply the Rollover  Reserve Fund to the payment of Approved
Leasing Expenses pursuant to the terms of this Section 7.5;  provided,  however,
if there is an Event of Default which is continuing, then Lender may credit such
Rollover  Reserve Fund  against the Debt in such  priority  and  proportions  as
Lender in its sole and absolute  discretion shall deem proper.  If the amount of
the Rollover  Reserve  Fund shall  exceed the amounts due for  Approved  Leasing
Expenses  pursuant  to  the  terms  hereof,  Lender  shall,  in  its  reasonable
discretion,  return any excess to Borrower;  provided,  however,  if there is an
Event of Default which is continuing, then Lender may credit such excess against
the Debt in such  priority  and  proportions  as Lender in its sole and absolute
discretion shall deem proper.

     7.5.2 GRANT OF SECURITY  INTEREST.  Borrower  hereby pledges and assigns to
Lender,  and grants to Lender a security  interest in, all of Borrower's  right,
title and interest in and to the Rollover  Reserve Fund, as security for payment
of all  sums  due  under  the  Loan  and the  performance  of all  other  terms,
conditions and provisions of the Loan Documents and this Agreement on Borrower's
part to be paid and performed.  Borrower shall not, without  obtaining the prior
written consent of Lender, further pledge, assign or grant any security interest

thereto,  or any levy to be made  thereon,  or any UCC-1  Financing  Statements,
except  those  naming  Lender as the  secured  party,  to be filed with  respect
thereto. This Agreement is, among other things,  intended by the parties to be a
security agreement for purposes of the Illinois Uniform Commercial Code.

unpaid  principal  balance of the Note; (c) amortization of the unpaid principal
balance of the Note;  or (d) all other sums payable  pursuant to this  Agreement

(a) no  Event  of  Default  shall  have  occurred  and be  continuing;  (b) such
expenditure  is for an  Approved  Leasing  Expense;  and  (c)  the  request  for

extent that Borrower is entitled to request funds and receive disbursements from
the  Rollover  Reserve  Fund  pursuant to this  Section  7.5.4,  Lender shall be
entitled to make partial draw  requests on said letter of credit for the amounts
so requested by Borrower and shall disburse such amounts in accordance  with the
terms of this Section; provided,  however, that if partial draw requests are not
permitted under said letter of credit then,  upon  Borrower's  first request for
disbursement of Rollover Reserve Fund sums, Lender shall make a draw request for
the full  amount  of the  letter  of credit  and  shall  hold such  funds in the
Rollover  Reserve Fund and disburse such funds in  accordance  with this Section
7.5.

     Section  7.6  PAYMENT OF  APPROVED  OPERATING  EXPENSES.  After a Cash Trap
Event,  Funds  held in the Cash  Collateral  Account  may be used  for  Approved
Operating Expenses, provided that such use shall be in Lender's discretion if an
Event of Default has occurred and remains uncured.  Provided an Event of Default
has not occurred, Borrower may from time to time send a request for disbursement
of funds in the Cash  Collateral  Account  for  payment  of  Approved  Operating
Expenses,  but not more than one (1) time per  month.  To the  extent  there are
funds available in the Cash Collateral Account in excess of the amounts required
to fund the Tax and Insurance  Escrow Fund, the Capital  Reserve Fund and to pay

previous disbursement and (E) that all previous  disbursements have been or will
be used to pay the previously  identified Approved Operating Expenses,  and (ii)

receives  from the Borrower a valid  request for a  disbursement  for payment of
Approved  Operating  Expenses  for the then  Current  Month  at  least  five (5)
Business Days prior to the Payment Date  occurring in such Current  Month,  then
the disbursement in respect of such Approved Operating Expenses shall be made to
Borrower on such Payment Date. If the Borrower  shall fail to validly  request a
disbursement  for payment of Approved  Operating  Expenses  for the then Current
Month at least five (5) Business  Days prior to the Payment Date in such Current
Month,  then the Lender shall  retain in the Deposit  Account an amount equal to


                                      -37-

the  anticipated  Operating  Expenses for the then Current Month as set forth in
the approved  Operating Budget for such month, and the Lender shall,  subject to
satisfaction of the preceding conditions, disburse same to the Borrower five (5)
Business  Days  after the  Lender  receives a valid  request  therefor.  Amounts
disbursed to the  Borrower  under this Section 7.6 shall be used by the Borrower
to pay  current  Approved  Operating  Expenses  and for no  other  purpose.  The

such 30-day period and thereafter diligently and expeditiously  proceeds to cure
the same, such 30-day period shall be extended for an additional  period of time

equity, take such action,  without notice or demand, that Lender deems advisable
to protect and enforce its rights  against  Borrower and in and to the Property,
including  declaring the Debt to be immediately due and payable,  and Lender may
enforce or avail  itself of any or all rights or  remedies  provided in the Loan
Documents  against  Borrower and the Property,  including all rights or remedies

clauses  (vi),  (vii) or (viii)  above,  the Debt and all other  obligations  of
Borrower  hereunder and under the other Loan  Documents  shall  immediately  and
automatically  become due and payable,  without  notice or demand,  and Borrower
hereby expressly waives any such notice or demand,  anything contained herein or
in any other Loan Document to the contrary notwithstanding.

     Section 8.2 REMEDIES.

     (a) Upon the  occurrence of an Event of Default,  all or any one or more of
the rights,  powers,  privileges and other remedies  available to Lender against
Borrower under this  Agreement or any of the other Loan  Documents  executed and
delivered  by Borrower or at law or in equity may be  exercised by Lender at any
time  and  from  time to time,  whether  or not all or any of the Debt  shall be
declared due and payable,  and whether or not Lender  shall have  commenced  any
foreclosure  proceeding  or other action for the  enforcement  of its rights and
remedies under any of the Loan Documents with respect to the Property.  Any such
actions taken by Lender shall be cumulative  and  concurrent  and may be pursued
independently,  singly, successively, together or otherwise, at such time and in
such order as Lender may determine in its sole discretion, to the fullest extent
permitted by law, without impairing or otherwise  affecting the other rights and
remedies of Lender  permitted by law,  equity or contract or as set forth herein
or in  the  other  Loan  Documents.  Without  limiting  the  generality  of  the
foregoing,  Borrower agrees that if an Event of Default is continuing (i) Lender
is not subject to any "one action" or  "election  of  remedies"  law or rule and
(ii) all liens and other rights, remedies or privileges provided to Lender shall
remain in full force and effect until Lender has  exhausted  all of its remedies
against the Property and the Mortgage has been foreclosed, sold and/or otherwise
realized upon in satisfaction of the Debt or the Debt has been paid in full.

     (b) Lender  shall have the right from time to time to  partially  foreclose
the Mortgage in any manner and for any amounts  secured by the Mortgage then due
and payable as determined by Lender in its sole  discretion  including,  without
limitation,  the following circumstances:  (i) in the event Borrower defaults in
the payment of one or more scheduled payments of principal and interest,  Lender
may  foreclose the Mortgage to recover such  delinquent  payments or (ii) in the
event Lender elects to  accelerate  less than the entire  outstanding  principal
balance of the Loan, Lender may foreclose the Mortgage to recover so much of the
principal balance of the Loan as Lender may accelerate.  Notwithstanding  one or
more partial foreclosures,  the Property shall remain subject to the Mortgage to
secure payment of sums secured by the Mortgage and not previously recovered.

     (c) Lender shall have the right from time to time to sever the Note and the
other  Loan  Documents  into one or more  separate  notes,  mortgages  and other
security  documents in such  denominations as Lender shall determine in its sole
discretion  for purposes of  evidencing  and  enforcing  its rights and remedies
provided  hereunder.  Borrower  shall execute and deliver to Lender from time to
time, promptly after the request of Lender, a severance agreement and such other
documents as Lender shall request in order to effect the severance  described in
the preceding  sentence,  all in form and substance  reasonably  satisfactory to
Lender.  Borrower hereby absolutely and irrevocably  appoints Lender as its true
and lawful attorney, coupled with an interest, in its name and stead to make and
execute all documents necessary or desirable to effect the aforesaid  severance,
Borrower ratifying all that its said attorney shall do by virtue thereof.


                                      -39-
<PAGE>
     Section 8.3 REMEDIES CUMULATIVE.  The rights, powers and remedies of Lender
under this  Agreement  shall be cumulative and not exclusive of any other right,
power  or  remedy  which  Lender  may have  against  Borrower  pursuant  to this
Agreement  or the  other  Loan  Documents,  or  existing  at law or in equity or
otherwise.   Lender's  rights,  powers  and  remedies  may  be  pursued  singly,
concurrently  or  otherwise,  at such  time  and in such  order  as  Lender  may
determine  in Lender's  sole  discretion.  No delay or omission to exercise  any
remedy,  right or power  accruing upon an Event of Default shall impair any such
remedy,  right or power or shall be construed as a waiver thereof,  but any such
remedy, right or power may be exercised from time to time and as often as may be
deemed  expedient.  A waiver of one Default or Event of Default  with respect to
Borrower  shall not be  construed  to be a waiver of any  subsequent  Default or
Event of Default by Borrower or to impair any remedy,  right or power consequent
thereon.

IX.  SPECIAL PROVISIONS

non-consolidation,  fraudulent  conveyance,  true sale and true contribution and

Property,  Borrower and its  Affiliates,  which  counsel and  opinions  shall be
reasonably satisfactory to Lender and the Rating Agencies;

          (c) make such representations and warranties as of the closing date of
any Secondary Market Transaction with respect to the Property,  Borrower and the
Loan Documents as are customarily  provided in such  transactions  and as may be
reasonably  requested by Lender or the Rating  Agencies and consistent  with the
facts covered by such  representations  and warranties as they exist on the date
thereof,   including  the  representations  and  warranties  made  in  the  Loan
Documents;

          (d) provide current  crtificates  of good standing and  qualification

requested  by Lender or the Rating  Agencies or  otherwise to effect a Secondary
Market Transaction, provided that nothing contained in this subsection (e) shall
result in a material economic change in the transaction.

Borrower  shall pay all  reasonable  third party costs and expenses  incurred by
Lender in connection with a Secondary Market Transaction

the Provided  Information and the Required Records may be included in disclosure
documents  in  connection  with a  Secondary  Market  Transaction,  including  a
prospectus or private placement  memorandum (each, a "Disclosure  Document") and
may also be included in filings  with the  Securities  and  Exchange  Commission
pursuant to the Securities Act of 1933, as amended (the  "Securities  Act"),  or
the  Securities and Exchange Act of 1934, as amended (the  "Exchange  Act"),  or
provided  or  made  available  to  investors  or  prospective  investors  in the
Securities, the Rating Agencies, and service providers or other parties relating
to the Secondary Market  Transaction.  In the event that the Disclosure Document
is required to be revised,  Borrower shall cooperate with Lender in updating the
Provided  Information  or  Required  Records  for  inclusion  or  summary in the
Disclosure  Document or for other use reasonably  required in connection  with a
Secondary Market Transaction by providing all current information  pertaining to
Borrower,  Manager and the Property  necessary to keep the  Disclosure  Document
accurate  and complete in all material  respects  with respect to such  matters.
Such  disclosure  may  include  the  opinion or  judgment  of Lender or Servicer
concerning  the Provided  Information  or other matters  disclosed,  and despite
reasonable good faith efforts by Lender and/or  Servicer,  the disclosure may be
erroneous  or  incomplete.   Borrower  hereby  consents  to  any  and  all  such
disclosures of such information.

     9.1.3 BORROWER OBLIGATIONS  REGARDING DISCLOSURE  DOCUMENTS.  In connection
with a Disclosure Document, Borrower shall:

          (a) if  requested  by Lender,  certify in writing  that  Borrower  has
carefully  examined those portions of such  Disclosure  Document,  pertaining to
Borrower,  the Property, the Manager and the Loan, including applicable portions
of  the  sections  entitled  "Special   Considerations",   "Description  of  the
Mortgages",  "Description  of the Mortgage Loans and Mortgaged  Property",  "The
Manager",  "The Borrower" and "Certain Legal Aspects of the Mortgage Loan",  and
such  portions  (and  portions of any other  sections  reasonably  requested and
pertaining to Borrower,  the  Property,  the Manager or the Loan) do not contain
any  untrue  statement  of a  material  fact or omit to  state a  material  fact
necessary  in  order  to  make  the  statements   made,  in  the  light  of  the
circumstances under which they were made, not misleading;

          (b) indemnify (i) any underwriter, syndicate member or placement agent
(collectively,  the  "Underwriters")  retained by Lender or its issuing  company
affiliate (the "Issuer") in connection with a Secondary Market Transaction, (ii)
Lender  and  (iii)  the  Issuer  that is named  in the  Disclosure  Document  or
registration   statement   relating  to  a  Secondary  Market  Transaction  (the
"Registration  Statement"),  and  each of the  Issuer's  directors,  each of its
officers who have signed the  Registration  Statement  and each person or entity
who  controls  the Issuer or the Lender  within the meaning of Section 15 of the
Securities Act or Section 30 of the Exchange Act (collectively within (iii), the
"CCA Group"), and each of its directors and each person who controls each of the
Underwriters, within the meaning of Section 15 of the Securities Act and Section
20 of the Exchange Act (collectively,  the "Underwriter  Group") for any losses,
claims,  damages or liabilities  (the  "Liabilities")  to which Lender,  the CCA
Group or the Underwriter Group may become subject (including  reimbursing all of
them for any  legal or other  expenses  actually  incurred  in  connection  with
investigating or defending the Liabilities) insofar as the Liabilities arise out
of or are based upon any untrue  statement  or alleged  untrue  statement of any
material  fact  contained  in  any  of  the  Required  Records  or in any of the
applicable  portions of such sections of the Disclosure  Document  applicable to
Borrower,  Manager,  the Property or the Loan, or arise out of or are based upon
the omission or alleged omission to state therein a material fact required to be
stated in the applicable portions of such sections or necessary in order to make
the  statements  in the  applicable  portions  of such  sections in light of the
circumstances  under which they were made, not  misleading,  provided,  however,
that  Borrower  shall not be required to  indemnify  Lender for any  Liabilities
relating to untrue  statements or omissions which Borrower  identified to Lender
in writing at the time of Borrower's  examination of such  Disclosure  Document;
and

          (c)  reimburse  any  member  of the CCA  Group  for any legal or other
expenses  reasonably incurred by such member in connection with investigating or
defending the Liabilities.

Borrower's  Liability  under  clause  (a) or  (b)  above  shall  be  limited  to
Liabilities  arising out of or based upon any such untrue  statement or omission
made therein in reliance upon and in conformity  with  information  furnished to
Lender by or on behalf of Borrower in connection  with the  preparation of those
portions  of the  Disclosure  Document  pertaining  to  Borrower,  Manager,  the
Property  or the  Loan or in  connection  with  the  underwriting  of the  debt,


                                      -41-
<PAGE>
including financial statements of Borrower, operating statements, rent rolls and
other  Required  Records,  environmental  site  assessment  reports and property
condition reports with respect to the Property.  The foregoing indemnity will be
in addition to any liability which Borrower may otherwise have.

     9.1.4 BORROWER  INDEMNITY  REGARDING  FILINGS.  In connection  with filings
under the Exchange Act, Borrower shall (i) indemnify  Lender,  the CCA Group and
the Underwriter Group for any Liabilities to which Lender,  the CCA Group or the
Underwriter  Group may become subject insofar as the Liabilities arise out of or
are  based  upon the  omission  or  alleged  omission  to state in the  Provided
Information  or Required  Records a material  fact  required to be stated in the
Provided  Information or Required Records in order to make the statements in the
Provided  Information or Required Records,  in light of the circumstances  under
which they were made not misleading and (ii) reimburse Lender,  the CCA Group or
the  Underwriter  Group for any legal or other  expenses  actually  incurred  by
Lender,  CCA Group or the  Underwriter  Group in  connection  with  defending or
investigating the Liabilities.

     9.1.5 INDEMNIFICATION  PROCEDURE.  Promptly after receipt by an indemnified
party under Section 9.1.3 or 9.1.4 of notice of the  commencement  of any action
for which a claim  for  indemnification  is to be made  against  Borrower,  such
indemnified party shall notify Borrower in writing of such commencement, but the
omission to so notify the Borrower will not relieve  Borrower from any liability
that it may have to any indemnified  party  hereunder  except to the extent that
failure to notify causes prejudice to Borrower.  In the event that any action is
brought  against  any  indemnified  party,  and  it  notifies  Borrower  of  the
commencement  thereof,  Borrower  will  be  entitled,  jointly  with  any  other
indemnifying  party, to participate therein and, to the extent that it (or they)
may elect by written notice  delivered to the  indemnified  party promptly after
receiving the aforesaid  notice of  commencement,  to assume the defense thereof
with counsel  satisfactory to such  indemnified  party in its discretion.  After
notice  from  Borrower  to such  indemnified  party  under this  Section  9.1.5,
Borrower shall not be responsible  for any legal or other expenses  subsequently
incurred by such indemnified  party in connection with the defense thereof other
than reasonable costs of investigation;  provided, however, if the defendants in
any  such  action  include  both  Borrower  and an  indemnified  party,  and any
indemnified  party  shall  have  reasonably  concluded  that there are any legal
defenses  available to it and/or other  indemnified  parties that are  different
from or additional to those available to Borrower, then the indemnified party or
parties  shall have the right to select  separate  counsel to assert  such legal
defenses and to otherwise participate in the defense of such action on behalf of
such indemnified party or parties. Borrower shall not be liable for the expenses
of more than one separate  counsel unless there are legal defenses  available to
it  that  are  different  from or  additional  to  those  available  to  another
indemnified party.

     9.1.6 CONTRIBUTION. In order to provide for just and equitable contribution
in circumstances in which the indemnity  agreement provided for in Section 9.1.3
or 9.1.4 is for any reason held to be unenforceable  by an indemnified  party in
respect of any  Liabilities (or action in respect  thereof)  referred to therein
which would otherwise be  indemnifiable  under Section 9.1.3 or 9.1.4,  Borrower
shall  contribute  to the amount paid or payable by the  indemnified  party as a
result of such Liabilities (or action in respect  thereof);  provided,  however,
that no Person  guilty of  fraudulent  misrepresentation  (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution  from any
Person not  guilty of such  fraudulent  misrepresentation.  In  determining  the
amount of  contribution  to which  the  respective  parties  are  entitled,  the
following  factors  shall be  considered:  (i) the CCA  Group's  and  Borrower's
relative knowledge and access to information  concerning the matter with respect
to which the claim was asserted; (ii) the opportunity to correct and prevent any
statement or omission; and (iii) any other equitable considerations  appropriate
in the  circumstances.  Lender  and  Borrower  hereby  agree  that it may not be
equitable if the amount of such  contribution were determined by pro rata or per
capita allocation.

     9.1.7  RATING  SURVEILLANCE.  Lender  will  retain the Rating  Agencies  to
provide rating  surveillance  services on  Securities.  The pro rata expenses of
such  surveillance  will  be  paid  for by  Borrower  based  on  the  applicable
percentage  of  such  expenses  determined  by  dividing  the  then  outstanding
Principal by the then  aggregate  outstanding  amount of the pool created in the
Secondary Market Transaction which includes the Loan.

     Section 9.4 EXCULPATION.  Subject to the qualifications below, Lender shall
not enforce the liability and  obligation of Borrower to perform and observe the
obligations  contained in the Note,  this  Agreement,  the Mortgage or the other
Loan  Documents by any action or proceeding  wherein a money  judgment  shall be
sought against Borrower,  except that Lender may bring a foreclosure  action, an
action for specific performance or any other appropriate action or proceeding to
enable  Lender to enforce and realize  upon its  interest  under the Note,  this
Agreement,  the Mortgage and the other Loan Documents,  or in the Property,  the
Rents, or any other  collateral  given to Lender pursuant to the Loan Documents;
provided, however, that, except as specifically provided herein, any judgment in
any such action or proceeding shall be enforceable  against Borrower only to the
extent of  Borrower's  interest in the  Property,  in the Rents and in any other
collateral given to Lender,  and Lender,  by accepting the Note, this Agreement,
the  Mortgage  and the other Loan  Documents,  agrees that it shall not sue for,
seek or demand any deficiency  judgment  against  Borrower in any such action or
proceeding  under or by reason of or under or in connection  with the Note, this
Agreement,  the Mortgage or the other Loan  Documents.  The  provisions  of this
section shall not,  however,  (a) constitute a waiver,  release or impairment of
any obligation evidenced or secured by any of the Loan Documents; (b) impair the
right of Lender to name Borrower as a party  defendant in any action or suit for
foreclosure   and  sale  under  the   Mortgage;   (c)  affect  the  validity  or
enforceability of or any guaranty made in connection with the Loan or any of the
rights  and  remedies  of Lender  thereunder;  (d) impair the right of Lender to
obtain the  appointment of a receiver;  (e) impair the enforcement of any of the
Assignments of Leases;  (f) constitute a prohibition  against Lender  commencing
any other appropriate  action or proceeding in order for Lender to fully realize
the security  granted by the  Mortgage or to exercise  its remedies  against the
Property;  or (g)  constitute  a waiver of the right of  Lender to  enforce  the
liability and  obligation of Borrower,  by money  judgment or otherwise,  to the
extent of any loss, damage, cost, expense,  liability, claim or other obligation
incurred by Lender  (including  attorneys' fees and costs  reasonably  incurred)
arising out of or in connection with the following:

     (i) fraud or intentional  misrepresentation by Borrower or any guarantor in
connection with the Loan;

     (ii) the gross negligence or willful misconduct of Borrower;

     (iii)  the  breach  of any  provision  in that  certain  Environmental  and
Hazardous  Substance  Indemnification  Agreement of even date herewith  given by
Borrower to Lender or in the Mortgage concerning  environmental laws,  hazardous
substances and asbestos and any  indemnification  of Lender with respect thereto
in either document;

     (iv)  physical  waste of the  Property,  or the  removal or disposal of any
portion of the Property;

     (v) the  misapplication  or  conversion  by Borrower  of (A) any  insurance
proceeds paid by reason of any loss, damage or destruction to the Property,  (B)
any awards or other amounts  received in connection with the condemnation of all
or a portion of the Property, or (C) any Rents following an Event of Default;

     (vi) failure to pay charges for labor or  materials  or other  charges that
can create  liens on any portion of the  Property  unless  such  charges are the
subject of a bona fide  dispute in which  Borrower is  contesting  the amount or
validity thereof;

     (vii) any security  deposits  collected  with respect to the Property which
are not delivered to Lender upon a foreclosure of the Property or action in lieu
thereof,  except to the  extent  any such  security  deposits  were  applied  in
accordance  with the  terms and  conditions  of any of the  Leases  prior to the
occurrence of the Event of Default that gave rise to such  foreclosure or action
in lieu thereof; and

     (viii) Borrower's indemnification of Lender set forth in Section 9.2.

Notwithstanding  anything to the  contrary in this  Agreement or any of the Loan
Documents,  (x) Lender shall not be deemed to have waived any right which Lender
may have under Sections 506(a),  506(b),  1111(b) or any other provisions of the
U.S.  Bankruptcy Code to file a claim for the full amount of the Debt secured by
the Mortgage or to require that all  collateral  shall continue to secure all of
the Debt owing to Lender in accordance with the Loan Documents, and (y) the Debt
shall be fully  recourse  to  Borrower  in the event  that:  (aa) the first full
monthly  payment of principal and interest  under the Note is not paid when due;
(bb) Borrower  fails to permit  on-site  inspections  of the Property,  fails to
provide financial information,  fails to maintain its status as a single purpose


                                      -43-
<PAGE>
entity or fails to appoint a new  property  manager  upon the  request of Lender
after an Event of Default, each as required by, and in accordance with the terms
and  provisions  of, this Loan Agreement and the Mortgage (cc) Borrower fails to
obtain  Lender's  prior written  consent to any  subordinate  financing or other
voluntary lien encumbering the Property other than a Permitted  Encumbrance;  or
(dd) Borrower fails to obtain  Lender's prior written consent to any assignment,
transfer,  or conveyance of the Property or any interest  therein as required by
the Mortgage.

     Section 9.5  TERMINATION OF MANAGER.  If an Event of Default is continuing,
Borrower shall, at the request of Lender, terminate the Management Agreement and
replace the Manager  with a manager  approved by Lender on terms and  conditions
satisfactory  to  Lender.  In  the  event  that  Borrower  does  not  propose  a
replacement manager to Lender for its approval within fifteen (15) business days
after the Lender's  request that  Borrower do so, Lender may propose two or more
such property managers for Borrower's  consideration.  If Borrower then fails to
select and retain one of such  property  managers  within  fifteen (15) business
days  thereafter,  Lender shall have the right to select a property  manager for
the Property,  and to enter into a management agreement with such manager in the
name of Borrower.  Borrower hereby appoints Lender its  attorney-in-fact,  which
appointment  is coupled with an interest,  for the purpose of entering into such
management agreement. The management agreement entered into between Borrower and
any Manager shall be in form and substance reasonably acceptable to Lender.

     Section 9.6 RETENTION OF SERVICER.  Lender reserves the right to retain the
Servicer  to act as its agent  hereunder  with such  powers as are  specifically
delegated  to the  Servicer  by Lender,  whether  pursuant  to the terms of this
Agreement,  the Pooling and Servicing  Agreement or the Cash Collateral  Account
Agreement  or  otherwise,  together  with such  other  powers as are  reasonably
incidental  thereto.  Borrower shall pay any reasonable fees and expenses of the
Servicer in  connection  with a  Defeasance  of the Note,  release of  Property,
assumption or modification of the Loan or enforcement of the Loan Documents.

     Section 10.7 WAIVER OF TRIAL BY JURY.  BORROWER AND LENDER HEREBY AGREE NOT
TO ELECT A TRIAL BY JURY OF ANY ISSUE  TRIABLE  OF RIGHT BY JURY,  AND WAIVE ANY
RIGHT TO TRIAL BY JURY  FULLY TO THE  EXTENT  THAT ANY SUCH  RIGHT  SHALL NOW OR
HEREAFTER EXIST WITH REGARD TO THE LOAN DOCUMENTS, OR ANY CLAIM, COUNTERCLAIM OR
OTHER ACTION ARISING IN CONNECTION  THEREWITH.  THIS WAIVER OF RIGHT TO TRIAL BY
JURY IS GIVEN KNOWINGLY AND VOLUNTARILY BY BORROWER AND LENDER,  AND IS INTENDED
TO ENCOMPASS  INDIVIDUALLY EACH INSTANCE AND EACH ISSUE AS TO WHICH THE RIGHT TO
A TRIAL BY JURY WOULD  OTHERWISE  ACCRUE.  LENDER AND  BORROWER  ARE EACH HEREBY
AUTHORIZED  TO FILE A COPY OF THIS  PARAGRAPH IN ANY  PROCEEDING  AS  CONCLUSIVE
EVIDENCE OF THIS WAIVER.

     Section 10.8 HEADINGS. The Article and/or Section headings and the Table of
Contents in this Agreement are included herein for convenience of reference only
and shall not constitute a part of this Agreement for any other purpose.

     Section  10.9  SEVERABILITY.  Wherever  possible,  each  provision  of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid under  applicable law, such provision shall be ineffective to the extent
of such  prohibition or invalidity,  without  invalidating the remainder of such
provision or the remaining provisions of this Agreement.

     Section 10.10  PREFERENCES.  Lender shall have the continuing and exclusive
right to apply or reverse and  reapply  any and all  payments by Borrower to any
portion of the obligations of Borrower hereunder. To the extent Borrower makes a
payment or payments to Lender, which payment or proceeds or any part thereof are
subsequently invalidated,  declared to be fraudulent or preferential,  set aside
or  required  to be repaid to a trustee,  receiver  or any other party under any
bankruptcy  law, state or federal law, common law or equitable  cause,  then, to
the extent of such payment or proceeds  received,  the obligations  hereunder or
part  thereof  intended to be  satisfied  shall be revived and  continue in full
force and  effect,  as if such  payment or  proceeds  had not been  received  by
Lender.

     Section  10.11  WAIVER OF NOTICE.  Borrower  shall not be  entitled  to any
notices of any nature  whatsoever from Lender except with respect to matters for
which this  Agreement or the other Loan  Documents  specifically  and  expressly
provide for the giving of notice by Lender to Borrower  and except with  respect
to matters for which Borrower is not, pursuant to applicable Legal Requirements,
permitted  to waive the  giving  of  notice.  To the  extent  permitted  by law,
Borrower  hereby  expressly  waives the right to receive  any notice from Lender
with respect to any matter for which this  Agreement or the other Loan Documents
do not specifically and expressly  provide for the giving of notice by Lender to
Borrower.

     Section  10.12  REMEDIES  OF  BORROWER.  In  the  event  that  a  claim  or
adjudication is made that Lender or its agents,  including Servicer,  have acted
unreasonably  or  unreasonably  delayed acting in any case where by law or under
this Agreement or the other Loan  Documents,  Lender or such agent,  as the case
may be, has an obligation to act  reasonably or promptly,  Borrower  agrees that
neither  Lender  nor its  agents,  including  Servicer,  shall be liable for any
monetary damages, and Borrower's sole remedies shall be limited to commencing an
action seeking  injunctive  relief or declaratory  judgment.  The parties hereto
agree  that any  action or  proceeding  to  determine  whether  Lender has acted
reasonably shall be determined by an action seeking declaratory judgment.

     Section 10.13 EXPENSES; INDEMNITY.

     (a) Borrower covenants and agrees to reimburse Lender (or the holder of the
Loan,  as  applicable)  upon receipt of written  notice from such holder for all
reasonable  costs  and  expenses  (including   reasonable  attorneys'  fees  and
disbursements)  incurred  by  Lender  in  connection  with (i) the  preparation,
negotiation,  execution  and  delivery  of this  Agreement  and the  other  Loan
Documents  and the  consummation  of the  transactions  contemplated  hereby and
thereby and all the costs of  furnishing  all  opinions by counsel for  Borrower
(including  any  opinions  requested by Lender as to any legal  matters  arising
under this  Agreement or the other Loan Documents with respect to the Property);
(ii) Borrower's ongoing performance of and compliance with Borrower's respective
agreements  and  covenants  contained  in  this  Agreement  and the  other  Loan
Documents on its part to be performed or complied  with after the Closing  Date,
including confirming  compliance with environmental and insurance  requirements;
(iii)  Lender's  ongoing  performance  and  compliance  with all  agreements and
conditions  contained in this Agreement and the other Loan Documents on its part
to be performed or complied with after the Closing Date;  (iv) the  negotiation,
preparation, execution, delivery and administration of any consents, amendments,
waivers or other  modifications  to this  Agreement and the other Loan Documents
and any other documents or matters requested by Lender;  (v) Borrower  complying
with  any  requests  made  pursuant  to  Section  9.1  hereof  (subject  to  the
limitations  contained in such section);  (vi) the filing and recording fees and
expenses,  title  insurance  and  reasonable  fees and  expenses  of counsel for
providing to Lender all required  legal  opinions,  and other  similar  expenses
incurred in creating  and  perfecting  the Liens in favor of Lender  pursuant to
this Agreement and the other Loan  Documents;  (vii) enforcing or preserving any
rights, in response to third party claims or the prosecuting or defending of any
action  or  proceeding  or other  litigation,  in each  case  against,  under or
affecting Borrower, this Agreement,  the other Loan Documents,  the Property, or
any other security given for the Loan; and (viii)  enforcing any  obligations of
or collecting  any payments due from Borrower  under this  Agreement,  the other
Loan  Documents  or with  respect  to the  Property  or in  connection  with any
refinancing  or  restructuring  of the credit  arrangements  provided under this
Agreement  in the nature of a  "work-out"  or of any  insolvency  or  bankruptcy
proceedings;  provided,  however,  that  Borrower  shall not be  liable  for the
payment of any such costs and expenses to the extent the same arise by reason of
the gross negligence,  illegal acts, fraud or willful  misconduct of Lender. Any
costs and  expenses  due and payable to Lender  hereunder  which are not paid by
Borrower  within ten (10) days after  demand may be paid from any amounts in the
Cash Collateral Account, with notice thereof to Borrower.

     (b) Borrower shall  indemnify and hold harmless Lender from and against any
and all other liabilities,  obligations,  losses, damages,  penalties,  actions,
judgments,  suits,  claims,  costs,  expenses and  disbursements  of any kind or
nature  whatsoever  (including the reasonable fees and  disbursements of counsel
for Lender in  connection  with any  investigative,  administrative  or judicial
proceeding commenced or threatened,  whether or not Lender shall be designated a
party thereto),  that may be imposed on, incurred by, or asserted against Lender
in any manner  relating  to or arising  out of (i) any breach by Borrower of its
obligations  under, or any material  misrepresentation  by Borrower contained in
this Agreement or the other Loan Documents,  (ii) the use or intended use of the
proceeds of the Loan or (iii) any information provided by Borrower, or contained
in any  documentation  approved  by  Borrower  and in any  way  relating  to the
issuance,  offering and sale of the Securities  (collectively,  the "Indemnified
Liabilities"); provided, however, that Borrower shall not have any obligation to
Lender hereunder to the extent that such Indemnified  Liabilities arise from the
gross  negligence,  illegal acts, fraud or willful  misconduct of Lender. To the
extent that the  undertaking  to  indemnify  and hold  harmless set forth in the
preceding  sentence may be  unenforceable  because it violates any law or public
policy,  Borrower shall  contribute the maximum  portion that it is permitted to
pay and satisfy  under  applicable  law to the payment and  satisfaction  of all
Indemnified Liabilities incurred by Lender.

     Section 10.14 EXHIBITS INCORPORATED. The Exhibits annexed hereto are hereby

     Section 10.15 OFFSETS, COUNTERCLAIMS AND DEFENSES. Any assignee of Lender's
interest in and to this  Agreement,  the Note and the other Loan Documents shall
take the same free and clear of all offsets, counterclaims or defenses which are
unrelated  to such  documents  which  Borrower  may  otherwise  have against any
assignor of such documents,  and no such unrelated counterclaim or defense shall
be interposed or asserted by Borrower in any action or proceeding brought by any
such assignee upon such  documents and any such right to interpose or assert any
such unrelated offset,  counterclaim or defense in any such action or proceeding
is hereby expressly waived by Borrower.

     Section 10.16 NO JOINT VENTURE OR  PARTNERSHIP.  Borrower and Lender intend
that the  relationships  created hereunder and under the other Loan Documents be
solely that of borrower  and  lender.  Nothing  herein or therein is intended to

relationship between Borrower and Lender nor to grant Lender any interest in the
Property other than that of mortgagee or lender.

     Section 10.17  PUBLICITY.  All news  releases,  publicity or advertising by

Borrower,  and of  Borrower's  properties,  or to a sale  in  inverse  order  of
alienation in the event of  foreclosure  of the interests  hereby  created,  and
agrees not to assert any right under any laws  pertaining to the  marshalling of
assets,  the sale in  inverse  order of  alienation,  homestead  exemption,  the
administration  of estates of  decedents,  or any other  matters  whatsoever  to
defeat,  reduce or affect the right of Lender under the Loan Documents to a sale
of the Property for the collection of the related indebtedness without any prior
or different resort for collection,  of the right of Lender or any deed of trust
trustee to the payment of the related  indebtedness  out of the net  proceeds of
the Property in preference to every other claimant whatsoever.

     Section 10.19 WAIVER OF  COUNTERCLAIM.  Borrower hereby waives the right to
assert a counterclaim,  other than a compulsory  counterclaim,  in any action or
proceeding brought against it by Lender or its agents, including Servicer.

     Section 10.20  CONFLICT;  CONSTRUCTION  OF  DOCUMENTS.  In the event of any
conflict  between the  provisions  of this  Agreement  and any of the other Loan
Documents,  the provisions of this Agreement  shall control.  The parties hereto
acknowledge  that  they were  represented  by  counsel  in  connection  with the
negotiation  and  drafting of the Loan  Documents  and that such Loan  Documents
shall not be subject to the  principle of construing  their meaning  against the
party which drafted same.

     Section 10.21 BROKERS AND FINANCIAL  ADVISORS.  Borrower hereby  represents
that it has dealt with no financial advisors, brokers,  underwriters,  placement
agents,  agents or finders in connection with the  transactions  contemplated by
this Agreement. Borrower and Lender hereby agree to indemnify and hold the other
harmless from and against any and all claims, liabilities, costs and expenses of
any kind in any way  relating to or arising from a claim by any Person that such
Person  acted  on  behalf  of the  indemnifying  party  in  connection  with the
transactions  contemplated  herein.  The  provisions of this Section 10.21 shall
survive the  expiration  and  termination of this Agreement and the repayment of
the Debt.

     Section 10.22 NO THIRD PARTY  BENEFICIARIES.  This  Agreement and the other
Loan  Documents  are solely for the benefit of Lender and  Borrower  and nothing
contained  in this  Agreement  or the other  Loan  Documents  shall be deemed to
confer upon anyone other than Lender and Borrower any right to insist upon or to
enforce the performance or observance of any of the obligations contained herein
or  therein.  All  conditions  to the  obligations  of  Lender  to make the Loan
hereunder are imposed  solely and  exclusively  for the benefit of Lender and no
other Person shall have standing to require  satisfaction  of such conditions in
accordance  with their terms or be entitled to assume that Lender will refuse to
make the Loan in the absence of strict compliance with any or all thereof and no
other Person shall under any circumstances be deemed to be a beneficiary of such
conditions,  any or all of which  may be  freely  waived  in whole or in part by
Lender if, in Lender's sole  discretion,  Lender deems it advisable or desirable
to do so.

     Section 2.1 THE LOAN.

     2.1.1  COMMITMENT.  Subject to and upon the terms and  conditions set forth
herein,  including the  conditions  precedent  set forth in Section 3.1,  Lender
hereby agrees to make the Loan to Borrower on the Closing Date, in the aggregate
original  principal  amount set forth in the Note and which Loan shall mature on
the  Stated  Maturity  Date.  Borrower  hereby  agrees to accept the Loan on the
Closing Date, subject to and upon the terms and conditions set forth herein.

     2.1.2  DISBURSEMENT TO BORROWER.  Borrower may request and receive only one
borrowing hereunder in respect of the Loan. Borrower shall receive the Loan upon
the Closing, subject to the direction given by Borrower as to the application of
Loan proceeds for the uses set forth in Section 2.1.4.  Any amount  borrowed and
repaid hereunder in respect of the Loan may not be reborrowed.

     2.1.3 THE NOTE.  The Loan shall be evidenced by the Note,  in the aggregate
original  principal amount of the Loan. The Note shall bear interest as provided
therein.  The Note shall be subject to  repayment  as provided  in Section  2.3,
shall be entitled to the benefits of this  Agreement and shall be secured by the
Mortgage and the other Loan Documents.

     2.1.4 USE OF PROCEEDS OF LOAN.  Borrower shall use the proceeds of the Loan
(i) to finance the Property and to pay costs and expenses incurred in connection
with the Closing of the Loan, as approved by Lender and (ii) with respect to the
remainder, if any, as Borrower directs.

     Section 2.2 INTEREST; MONTHLY PAYMENTS.

     2.2.1 GENERALLY.

     (a) From the date hereof through but not including the Optional  Prepayment
Date,  Borrower shall pay interest on the outstanding  principal  balance of the
Loan at the Interest Rate.

     (b) On the date hereof, Borrower shall pay interest at the Interest Rate on
the  outstanding  principal  balance of the Loan from the Closing  Date  through
November 10, 1998.  Commencing with the Payment Date on December 11, 1998 and on
each and every Payment Date thereafter  through and including the Maturity Date,
the principal amount of the Loan and interest thereon at the Interest Rate shall
be payable in equal  monthly  installments  of  $147,847.15  (the  "Monthly Debt
Service Payment  Amount");  such Monthly Debt Service Payment Amount being based
on the Interest  Rate and a 360-month  amortization  schedule.  The Monthly Debt
Service  Payment  Amount due on any  Payment  Date shall first be applied to the
payment of interest  accrued from the eleventh (11th) day of the month preceding
the Payment  Date through the tenth (10th) day of the month in which the Payment
Date  occurs,  notwithstanding  that the  Payment  Date may have  been  deferred
because  the  eleventh  (11th)  day of such  month is not a  Business  Day.  The
remainder of such Monthly  Debt Service  Payment  Amount shall be applied to the
reduction of the outstanding principal balance of the Note.

     (c) From and after the Optional Prepayment Date, interest on the Loan shall
accrue at the Revised Interest Rate and shall be payable as provided in Sections
2.2.2 and 2.2.3.

     2.2.2 ACCRUED  INTEREST.  From and after the Optional  Prepayment Date, all
interest  accruing  in  respect  of the  Note in  excess  of the  Interest  Rate
("Accrued Interest") shall be deferred,  be added to the Debt and, to the extent
permitted by  applicable  law,  accrue  interest at the Revised  Interest  Rate,
compounded monthly.  All Accrued Interest and interest on Accrued Interest shall
be due and payable on the Maturity Date.

     2.2.3 PROPERTY CASH FLOW  ALLOCATION  AFTER THE OPTIONAL  PREPAYMENT  DATE.
Commencing on the Optional  Prepayment  Date and continuing on each Payment Date
thereafter until the entire Debt has been paid in full, any Rents deposited into
the Cash  Collateral  Account (or  otherwise  received by  Borrower)  during the
immediately  preceding  calendar  month  shall  be  applied  as  follows  in the
following order of priority unless an Event of Default exists:

     (a)  First, to make required payments to the Tax and Insurance Escrow Fund;


                                      -11-
<PAGE>
     (b)  Second,  to Lender to pay the  Monthly  Debt  Service  Payment  Amount
          (plus, if applicable, interest at the Default Rate);

     (c)  Third, payments for Approved Operating Expenses;

     (d) Fourth, to make required payments to the Capital Reserve Fund;

     (g) Fifth, to make required payments to the Rollover Reserve Fund;

     (f)  Sixth,  payments to Lender to prepay the outstanding principal balance
          under the Note until paid in full;

     (g)  Seventh, payments to Lender to be applied against Accrued Interest and
          interest accrued thereon; and

     (h)  Lastly, payments to Borrower of any excess amounts.

Notwithstanding anything herein to the contrary, the failure of Borrower to make
all of the payments  required under clauses (a) through (d) above in full on the
Optional  Prepayment Date and on each Payment Date thereafter shall constitute a
Default under this Agreement.  However, the failure of Borrower to pay principal
amounts  due under  clause (e) and any  Accrued  Interest or interest on Accrued
Interest on a Payment  Date as a result of  insufficient  Rents for such payment
shall not constitute a Default  hereunder.  All Accrued  Interest or interest on
Accrued Interest shall nonetheless be due and payable on the Maturity Date.

     2.2.4 DEFAULT RATE.  After the occurrence and during the  continuance of an
Event of Default,  the entire  outstanding  principal  balance of the Loan shall
bear interest at the Default Rate, and shall be payable upon demand from time to
time, to the extent  permitted by applicable  law.  Payment or acceptance of the
increased rates provided for in this  subsection is not a permitted  alternative
to timely  payment and shall not  constitute a waiver of any Default or Event of
Default or an amendment to this  Agreement or any other Loan  Document and shall
not otherwise prejudice or limit any rights or remedies of Lender.

     Section 2.3 LOAN REPAYMENT AND DEFEASANCE.

     2.3.1   REPAYMENT.   Borrower   shall  repay  any   outstanding   principal
indebtedness of the Loan in full on the Maturity Date of the Loan, together with
interest  thereon to (but  excluding)  the date of repayment.  Other than as set
forth in Section 2.3.2 below,  Borrower shall have no right to prepay all or any
portion of Loan  during the period  commencing  on the  Closing  Date to but not
including the Optional  Prepayment Date. From and after the Optional  Prepayment
Date,  the Loan may be prepaid in whole or in part  without  penalty or premium,
including without limitation the Yield Maintenance Premium.

     2.3.2 MANDATORY  PREPAYMENTS.  The Loan is subject to mandatory prepayment,
without  premium or penalty  except as  provided  in Section  7.1.2,  in certain
instances of Insured  Casualty or  Condemnation  (each a  "Casualty/Condemnation
Prepayment"),  in the manner and to the extent set forth in  Sections  7.1.2 and
Section 7.1.3 hereof. Each  Casualty/Condemnation  Prepayment shall be made on a
Payment Date and include all accrued and unpaid  interest on the amount  prepaid
up to but not  including  such Payment  Date or, if not paid on a Payment  Date,
include  interest  that  would have  accrued  on the  amount  prepaid to but not
including the next Payment Date.

     2.3.3 VOLUNTARY DEFEASANCE OF THE NOTE.

     (a) Subject to the terms and  conditions  set forth in this Section  2.3.3,
Borrower  may  defease  all or any  portion  of the Loan  evidenced  by the Note
(hereinafter, a "Defeasance"); provided, that no such Defeasance may occur prior
to the Release  Date.  Each  Defeasance  shall be subject,  in each case, to the
satisfaction of the following conditions precedent:

     (i)  Borrower  shall  provide not less than thirty (30) days prior  written
          notice to Lender specifying a Payment Date (the "Defeasance  Date") on

          principal amount of the Note to be defeased.

     (ii) Borrower  shall pay to Lender all accrued  and unpaid  interest on the
          principal  balance  of the Note to but not  including  the  Defeasance
          Date.  If for any reason the  Defeasance  Date is not a Payment  Date,
          Borrower  shall also pay interest  that would have accrued on the Note
          to but not including the next Payment Date.

     (iii)Borrower shall pay to Lender all other sums,  not including  scheduled
          interest  or  principal  payments,  then  due  under  the  Note,  this
          Agreement, the Mortgage and the other Loan Documents.

     (v)  Borrower shall pay to Lender the required  Defeasance  Deposit for the
          Defeasance.

     (vi) In the event only a portion of the Loan  evidenced  by the Note is the
          subject of the  Defeasance,  Borrower  shall  execute  and deliver all
          necessary  documents  to amend  and  restate  the Note and  issue  two
          substitute notes: one having a principal balance equal to the defeased
          portion of the original Note (the "Defeased Note") and one note having
          a principal  balance equal to the  undefeased  portion of the original
          Note (the  "Undefeased  Note").  The Defeased Note and Undefeased Note
          shall  have  identical  terms as the Note,  except  for the  principal
          balance.  A  Defeased  Note  cannot  be the  subject  of  any  further
          Defeasance.

     (vii)Borrower shall execute and deliver a security  agreement,  in form and
          substance  satisfactory  to Lender,  creating a first priority lien on
          the  Defeasance  Deposit and the U.S.  Obligations  purchased with the
          Defeasance  Deposit in accordance  with this provision of this Section
          2.3.3 (the "Security Agreement").

     (viii) Borrower  shall  deliver an opinion of counsel for  Borrower in form
          reasonably  satisfactory to Lender stating,  among other things,  that
          (A) Lender has a perfected  first  priority  security  interest in the
          Defeasance Deposit and the U.S. Obligations  delivered by Borrower and
          (B) said U.S.  Obligations  have been  validly  assigned  to the REMIC
          Trust.

     (ix) Lender shall receive  evidence in writing from the  applicable  Rating
          Agencies  to the  effect  that such  Defeasance  will not  result in a
          reduction,  withdrawal  or  requalification  of the  ratings in effect
          immediately  prior to such  Defeasance  for the  Securities  issued in
          connection with the Securitization which are then outstanding.

     (x)  If required by the  applicable  Rating  Agencies,  Borrower shall also
          deliver or cause to be  delivered  a  non-consolidation  opinion  with

          to Lender and the applicable Rating Agencies.

     (xi) Borrower shall deliver an Officer's  Certificate  certifying  that the
          requirements set forth in this Section 2.3.3(a) have been satisfied.

     (xii)Borrower   shall  deliver  such  other   certificates,   documents  or

          associated  with a release of Lien as  provided  in Section 2.4 hereof
          and reasonable attorney's fees and expenses.

     (b) In connection  with each  Defeasance of all or any portion of the Note,
Borrower  hereby  appoints  Lender  as its agent  and  attorney-in-fact  for the
purpose of using the  Defeasance  Deposit to purchase  U.S.  Obligations  (which
purchases, if made by Lender, shall be made by Lender on an arms-length basis at
then  prevailing  market  rates) which  provide  payments on or prior to, but as
close as possible to, all successive Payment Dates after the Defeasance Date, in
the case of a Defeasance  for the entire  outstanding  principal  balance of the
Note, or the Defeased  Note,  in the case of a Defeasance  for only a portion of
the outstanding principal balance of the Loan, as applicable (including,  on the
Optional  Prepayment Date, the outstanding  principal balance of either the Note
or the Defeased  Note),  and in amounts equal to the  scheduled  payments due on
such dates under the Note or the Defeased  Note, as applicable  (the  "Scheduled
Defeasance  Payments").  Borrower,  pursuant to the Security  Agreement or other
appropriate  document,  shall irrevocably authorize and direct that the payments
received from the U.S. Obligations may be made directly to Lender and applied to
satisfy the  obligations  of Borrower  under the Note or the Defeased  Note,  as
applicable.  Any  portion  of the  Defeasance  Deposit  in excess of the  amount
necessary to purchase the U.S.  Obligations  required by this Section 2.3(a) and

Obligations shall be applied to payments under the Note or the Defeased Note, as

Borrower") and Borrower shall  transfer and assign all  obligations,  rights and
duties under and to the Note or the Defeased Note, as applicable,  together with
the pledged U.S.  Obligations to such Successor Borrower.  The obligation of CCA
to  establish  or  designate  a  Successor  Borrower  shall be  retained  by CCA
notwithstanding the sale or transfer of this Agreement unless such obligation is
specifically assumed by the transferee. Such Successor Borrower shall assume the
obligations under the Note or the Defeased Note, as applicable, and the Security
Agreement  and  Borrower  shall  be  relieved  of  its  obligations  thereunder,
hereunder  and  under the  other  Loan  Documents  (except  for those  which are
expressly  stated to survive).  Borrower  shall pay $1,000 to any such Successor
Borrower as  consideration  for assuming the  obligations  under the Note or the
Defeased  Note,  as  applicable,  and the  Security  Agreement.  Notwithstanding
anything in this  Agreement to the contrary,  no other  assumption  fee shall be
payable upon a transfer of the Note or the Defeased Note in accordance with this
Section 2.3.3, but Borrower shall pay all costs and expenses incurred by Lender,
including  Lender's  reasonable  attorneys'  fees  and  expenses,   incurred  in
connection therewith.

the Lien of the Mortgage on the Property.

     2.4.1 RELEASE OF THE PROPERTY.

     (a) If Borrower  has elected to defease the Note in its  entirety,  and the
requirements of Section 2.3 have been satisfied,  the Property shall be released
from  the  Lien of the  Mortgage  and the  other  Loan  Documents  and the  U.S.
Obligations,  pledged  pursuant  to the  Security  Agreement,  shall be the sole
source of collateral securing the Note.

     (b) In connection  with the release of the Lien,  Borrower  shall submit to
Lender,  not less than twenty (20) days prior to the Defeasance  Date, a release
of Lien (and related Loan  Documents) for the Property (for execution by Lender)
in a form  appropriate in the State  reasonably  satisfactory  to Lender and all
other  documentation  Lender  requires to be delivered by Borrower in connection
with such release,  together with an Officer's Certificate  certifying that such
documentation  (i) is in compliance with all Legal  Requirements,  and (ii) will
effect such release in accordance with the terms of this Agreement.

Business Day thereafter.

     2.5.2  COMPUTATIONS.  Interest  payable  hereunder  or  under  the  Note by

under the Loan Documents is not paid by Borrower on the date on which it is due,
Borrower  shall pay to Lender upon demand an amount  equal to the lesser of five
percent (5%) of such unpaid sum or the maximum  amount  permitted by  applicable
law in order to defray the expense incurred by Lender in handling and processing
such delinquent payment and to compensate Lender for the loss of the use of such
delinquent  payment.  Any such amount  shall be secured by the  Mortgage and the
other Loan Documents.

     Section 2.6 CASH MANAGEMENT ARRANGEMENTS.

     (a) All Rents (other than security  deposits) will be transmitted  directly
into an  account  maintained  by  Borrower  but  controlled  by Lender at a bank

                                      -14-
<PAGE>
separate "A" account  (the "A"  Account) and "B" Account (the "B" Account)  with
the Collection Account Bank.  Borrower shall cause all Rents to be sent directly
to the Collection  Account Bank by tenants (where  practicable) for deposit into
the "A" Account.  All other income or revenue received by Borrower or Manager in

of receipt.  Until the earlier to occur of (i) the Optional  Prepayment  Date or
(ii) an Event of Default  (either such  occurrence,  a "Cash Trap  Event"),  the
Collection Account Bank will transfer deposits that are cleared on a daily basis
from the "A" Account to the "B" Account which shall be an account not subject to
any restrictions and under the sole control of Borrower.  Upon the occurrence of
a Cash Trap Event, the Collection  Account Bank will transfer  property receipts
that  are  cleared  on a daily  basis to the Cash  Collateral  Account  Bank for
deposit into the Cash Collateral  Account.  The duties of the Collection Account
Bank and the  application  and  disbursement  of all  funds  deposited  with the
Collection Account Bank shall be governed by the terms of this Agreement and the
Collection Account Agreement.  Any amounts so deposited into the Cash Collateral
Account  shall be  applied  and  disbursed  in  accordance  with the  terms  and
provisions of this Agreement and the Cash Collateral Account Agreement.

     (b) Lender  shall have a senior  security  interest  in the  aforementioned
accounts  and  all  subaccounts  established  thereunder  (other  than  the  "B"
Account).  The upfront and ongoing  expenses of  maintaining  such  accounts and
subaccounts, and any other accounts and reserves maintained pursuant to the Loan
Documents,  shall be the responsibility of Borrower. Funds in each account shall
be invested for the benefit of Borrower in Permitted Investments.

     (c) Anything  hereinabove in this Section to the contrary  notwithstanding,
from and after the occurrence and during the continuance of an Event of Default,
100% of all Rents and other sums deposited  into the  Collection  Account in any
month  which  remain in the Cash  Collateral  Account  shall be  applied  to the
payment of Debt Service on the Loan (including,  if applicable,  interest at the
Default Rate),  required reserves and Approved  Operating Expenses and/or to the
payment  of the  principal  amount of the Note,  in such  order as Lender  shall
determine in its sole discretion.

IV.  REPRESENTATIONS AND WARRANTIES
     ------------------------------

     Section 4.1 BORROWER  REPRESENTATIONS.  Borrower represents and warrants as
of the date hereof and as of the Closing Date that:

     (a) Organization.  Borrower has been duly organized and is validly existing
and in  good  standing  with  requisite  limited  liability  company  power  and
authority to own its  properties  and to transact the  businesses in which it is
now engaged.  Borrower is duly  qualified to do business and is in good standing
in each jurisdiction  where it is required to be so qualified in connection with
its  properties,  businesses  and  operations.  Borrower  possesses  all rights,
licenses,  permits and authorizations,  governmental or otherwise,  necessary to
entitle it to own its  properties  and to transact the businesses in which it is
now engaged  (other than those which the failure to have would not reasonably be
expected to have a material adverse effect on the Borrower,  the Property or the
Loan),  and the sole  business  of  Borrower is the  ownership,  management  and
operation of the Property.

     (b)  Proceedings.  Borrower has taken all necessary action to authorize the
execution,  delivery  and  performance  of this  Agreement  and the  other  Loan
Documents.  This Agreement and such other Loan Documents have been duly executed
and  delivered  by or on behalf of  Borrower  and  constitute  legal,  valid and
binding obligations of Borrower  enforceable against Borrower in accordance with
their respective terms, subject to applicable bankruptcy, insolvency and similar
laws affecting rights of creditors generally, and subject, as to enforceability,
to general principles of equity (regardless of whether  enforcement is sought in
a proceeding in equity or at law).

     (c) No Conflicts. The execution, delivery and performance of this Agreement
and the other Loan  Documents by Borrower  will not conflict with or result in a
breach of any of the terms or provisions of, or constitute a default  under,  or
result in the creation or imposition of any lien,  charge or encumbrance  (other
than  pursuant  to the Loan  Documents)  upon any of the  property  or assets of
Borrower pursuant to the terms of any indenture,  mortgage,  deed of trust, loan
agreement,  partnership  agreement  or other  agreement or  instrument  to which
Borrower is a party or by which  Borrower's  property or assets is subject,  nor
will such action result in any violation of the provisions of any statute or any
order,  rule or  regulation of any court or  governmental  agency or body having
jurisdiction  over Borrower or any of its  properties or assets (other than such
actions  described  herein  which  would not  reasonably  be  expected to have a
material  adverse effect on the Borrower,  the Property,  or the Loan),  and any
consent,  approval,  authorization,  order,  registration or qualification of or
with any court or any such regulatory  authority or other governmental agency or
body required for the  execution,  delivery and  performance  by any Borrower of
this  Agreement  or any other Loan  Documents  has been  obtained and is in full
force and effect.

     (d)  Litigation.  There are no actions,  suits or  proceedings at law or in
equity by or before any  Governmental  Authority  or other agency now pending or
threatened against or affecting Borrower or the Property,  which actions,  suits
or proceedings, if determined against Borrower or the Property, might materially
adversely affect the condition  (financial or otherwise) or business of Borrower
or the condition or ownership of the Property.

     (e)  Agreements.  Borrower is not a party to any agreement or instrument or
subject to any  restriction  which would  reasonably  be expected to  materially
adversely affect Borrower or the Property, or Borrower's business, properties or
assets,  operations  or condition,  financial or  otherwise.  Borrower is not in
default in any material respect in the performance, observance or fulfillment of
any of the  obligations,  covenants or  conditions  contained  in any  Permitted
Encumbrance  or any other  agreement or  instrument to which it is a party or by
which it or the Property is bound.

     (f)  Title.  Borrower  has  good  and  insurable  title  in fee to the real
property  comprising part of the Property,  and good title to the balance of the
Property,   free  and  clear  of  all  Liens  whatsoever  except  the  Permitted

                                      -17-

<PAGE>
Encumbrances,  such other Liens as are permitted  pursuant to the Loan Documents
and the Liens created by the Loan Documents. The Mortgage when properly recorded
in the appropriate records,  together with any Uniform Commercial Code financing
statements  required  to be filed in  connection  therewith,  will  create (i) a
valid, perfected first priority lien on the Property,  subject only to Permitted
Encumbrances  and the Liens  created by the Loan  Documents  and (ii)  perfected
security  interests  in and to, and  perfected  collateral  assignments  of, all
personalty  (including the Leases), all in accordance with the terms thereof, in
each case  subject only to any  applicable  Permitted  Encumbrances,  such other
Liens as are permitted  pursuant to the Loan  Documents and the Liens created or
permitted by the Loan  Documents.  The Permitted  Encumbrances do not materially
adversely  affect the value or use of the  Property,  or  Borrower's  ability to
repay the Loan.  There are no claims for  payment for work,  labor or  materials
affecting  the  Property  which are or may  become a lien  prior to, or of equal
priority with, the Liens created by the Loan Documents.

     (g) No Bankruptcy Filing.  Borrower is not contemplating  either the filing
of a petition by it under any state or federal  bankruptcy or insolvency laws or
the  liquidation  of all or a major  portion  of its  assets  or  property,  and
Borrower  has no knowledge  of any Person  contemplating  the filing of any such
petition against it.

     (h) Full and Accurate Disclosure.  No statement of fact made by Borrower in
this  Agreement  or in any of the  other  Loan  Documents  contains  any  untrue
statement of a material  fact or omits to state any material  fact  necessary to
make statements contained herein or therein not misleading. There is no material
fact  presently  known to Borrower  which has not been disclosed to Lender which
adversely affects,  nor as far as Borrower can foresee,  might adversely affect,
the Property or the business,  operations or condition  (financial or otherwise)
of Borrower.

     (i) No Plan Assets.  Borrower is not an "employee benefit plan," as defined
in Section 3(3) of ERISA, subject to Title I of ERISA, and none of the assets of
Borrower  constitutes or will constitute "plan assets" of one or more such plans
within the meaning of 29 C.F.R. Section 2510.3-101.

     (j)  Compliance.  To the best of  Borrower's  knowledge,  Borrower  and the
Property and the use thereof comply in all material respects with all applicable
Legal Requirements, including building and zoning ordinances and codes. Borrower
has not  received  notice  of any  default  or  violation  of any  order,  writ,
injunction,  decree or demand of any  Governmental  Authority,  the violation of
which is likely to  materially  adversely  affect the  condition  (financial  or
otherwise)  or  business  of  Borrower.  There has not been and  shall  never be
committed by Borrower or, to Borrower's  actual  knowledge,  any other person in
occupancy  of or involved  with the  operation or use of the Property any act or
omission  affording the federal  government or any state or local government the
right of  forfeiture  as against the  Property or any part thereof or any monies
paid in performance of Borrower's  obligations  under any of the Loan Documents.
Borrower hereby covenants and agrees not to commit or permit,  and shall use its
commercially  reasonable  efforts to  prevent  any other  person or entity  from
committing, any act or omission affording such right of forfeiture.

     (k)  Contracts.  Except as set forth on  Schedule  1, there are no material
contracts  affecting the Property which are not terminable on one month's notice
or less without cause and without  penalty or premium.  All contracts  affecting
the Property  (except for the  Management  Agreement)  have been entered into at
arms-length  in the ordinary  course of  Borrower's  business and all  contracts
affecting the Property  (including  the  Management  Agreement)  provide for the
payment of fees in amounts and upon terms comparable to existing market rates.

     (l) Financial Information.  All financial data, including the statements of
cash flow and income and operating  expense,  that have been delivered to Lender
by Borrower in respect of the Property (i) are true, complete and correct in all
material  respects,  (ii)  accurately  represent the financial  condition of the
Property as of the date of such  reports and (iii) to the extent  prepared by an
independent  certified public  accounting firm, have been prepared in accordance
with  GAAP  consistently  applied  throughout  the  periods  covered,  except as
disclosed  therein.  Borrower has no  contingent  liabilities,  liabilities  for
taxes,  unusual  forward or long-term  commitments  or unrealized or anticipated
losses  from  any  unfavorable  commitments  that  are  known  to  Borrower  and
reasonably  likely to have a  materially  adverse  effect on the Property or the
operation  thereof,  except  as  referred  to or  reflected  in  said  financial
statements.  Since  the date of such  financial  statements,  there  has been no
materially adverse change in the financial condition,  operations or business of
Borrower from that set forth in said financial statements.



                                      -18-
<PAGE>
     (m)  Condemnation.  No Condemnation or other  proceeding has been commenced
or, to Borrower's  best knowledge,  is  contemplated  with respect to all or any
portion of the Property or for the  relocation of roadways  providing  access to
the Property.

     (n) Federal Reserve  Regulations.  No part of the proceeds of the Loan will
be used for the purpose of purchasing or acquiring any "margin stock" within the
meaning of Regulation U of the Board of Governors of the Federal  Reserve System
or for any other purpose which would be  inconsistent  with such Regulation U or
any other Regulations of such Board of Governors, or for any purposes prohibited
by Legal  Requirements  or by the terms and  conditions of this Agreement or the
other Loan Documents.

     (o)  Utilities  and Public  Access.  The  Property  has rights of access to
public  ways and is served  by  water,  sewer,  sanitary  sewer and storm  drain
facilities  adequate to service the Property for its  respective  intended uses.
All public utilities necessary to the full use and enjoyment of the Property are
located in the public right-of-way  abutting the Property.  To Borrower's actual
knowledge,  all roads  necessary  for the use of the Property for their  current
respective purposes have been completed and dedicated to public use and accepted
by all Governmental Authorities.

     (p) Not a Foreign  Person.  Borrower is not a "foreign  person"  within the
meaning ofss.1445(f)(3) of the Code.

     (q)  Separate  Lots.  The  Property is comprised of one (1) or more parcels
which  constitutes  a separate tax lot and does not  constitute a portion of any
other tax lot not a part of the Property.

     (r) Assessments.  To the best of Borrower's knowledge, there are no pending
or proposed  special or other  assessments for public  improvements or otherwise
affecting  the  Property,  nor are there any  contemplated  improvements  to the
Property that may result in such special or other assessments.

     (s)  Enforceability.  The Loan  Documents  are not  subject to any right of
rescission,  set-off, counterclaim or defense by Borrower, including the defense
of usury,  nor would the exercise of any of the terms of the Loan Documents,  or
the exercise of any right thereunder,  render the Loan Documents  unenforceable,
and Borrower has not asserted any right of rescission,  set-off, counterclaim or
defense with respect thereto.

     (t) No Prior  Assignment.  There are no  assignments  of the  Leases or any
portion  of the Rents due and  payable or to become  due and  payable  which are
presently outstanding.

     (u) Insurance.  Borrower has obtained and has delivered to Lender insurance
certificates reflecting the insurance coverages,  amounts and other requirements
set forth in this Agreement.

     (v) Use of Property. The Property is used exclusively as an office building
and other appurtenant and related uses.

     (w)  Certificate  of  Occupancy;  Licenses.  All  material  certifications,
permits,  licenses and  approvals,  including  certificates  of  completion  and
occupancy permits and any applicable liquor licenses required for the legal use,
occupancy and operation of the Property  (collectively,  the  "Licenses"),  have
been obtained and are in full force and effect. Borrower shall keep and maintain
all licenses necessary for the operation of the Property.  The use being made of
the Property is in conformity with the  certificate of occupancy  issued for the
Property.

     (x) Flood Zone. To Borrower's actual knowledge, none of the Improvements on
the  Property  are  located  in an  area  identified  by the  Federal  Emergency
Management Agency as an area having special flood hazards.

     (y) Physical  Condition.  To  Borrower's  actual  knowledge,  the Property,
including all buildings,  improvements,  parking  facilities,  sidewalks,  storm
drainage  systems,  roofs,  plumbing  systems,  HVAC  systems,  fire  protection
systems, electrical systems, equipment,  elevators,  exterior sidings and doors,
landscaping,  irrigation  systems  and all  structural  components,  are in good
condition,  order  and  repair in all  material  respects;  and  there  exist no
structural or other material defects or damages in the Property,  whether latent
or otherwise.  Borrower has not received  notice from any  insurance  company or
bonding  company of any defects or  inadequacies  in the  Property,  or any part
thereof,  which would adversely affect the insurability of the same or cause the
imposition of extraordinary premiums or charges thereon or of any termination or
threatened termination of any policy of insurance or bond.

                                      -19-
<PAGE>
     (z)  Appraised  Value.  To  Borrower's   actual   knowledge,   all  of  the
improvements  which were  included in  determining  the  appraised  value of the
Property lie wholly within the boundaries and building  restriction lines of the
Property,  and  no  improvements  on  adjoining  properties  encroach  upon  the
Property, and no easements or other encumbrances upon the Property encroach upon
any of the  improvements,  so as to  affect  the value or  marketability  of the
Property except those which are insured against by title insurance.

     (aa) Leases. Attached hereto as Schedule 2 is a rent roll (the "Rent Roll")
for the  Property.  The Rent Roll is true,  correct and complete in all material
respects with respect to the subject matter thereof.  The only Leases  affecting
the  Property  are those  reflected in the Rent Roll.  To  Borrower's  knowledge
following inquiry as a duly diligent property purchaser,  except as set forth in
Schedule  1: (i) each Lease is in full force and  effect;  (ii) except for those
Leases with terms that have not yet commenced, the tenants under the Leases have
accepted  possession of and are in occupancy of all of their respective  demised
premises  (unless  such  demised  premises  or  portions   thereof,   have  been
subleased),  have  commenced the payment of rent under such Leases and there are
no offsets,  claims or defenses to the enforcement thereof;  (iii) all rents due
and payable under the Leases have been paid and no portion thereof has been paid
for any period  more than thirty  (30) days in  advance;  (iv) the rent  payable
under  each Lease is the amount set forth in the Rent Roll and there is no claim
or basis for a claim by the tenant thereunder for an adjustment to the rent; (v)
no tenant has made any claim against the landlord under the Leases which remains
outstanding  and there are no  defaults  on the part of the  landlord  under any
Lease and no event has occurred  which,  with the giving of notice or passage of
time,  or both,  would  constitute  such  default;  and (vi) there is no present
material default by any tenant under any Lease.  None of the Leases contains any
option to purchase or right of first  refusal to  purchase  the  Property or any
part thereof. The Leases have not been assigned or pledged except to Lender, and
no  other  person  whatsoever  has  any  interest  therein  except  the  tenants
thereunder.

     (bb) Survey. To Borrower's  actual  knowledge,  the survey for the Property
delivered to Lender in connection  with this  Agreement does not fail to reflect
any material matter affecting the Property or the title thereto.

     (cc)  Filing  and  Recording  Taxes.  All  transfer  taxes,   deed  stamps,
intangible taxes or other amounts in the nature of transfer taxes required to be
paid by any Person under  applicable Legal  Requirements  currently in effect in
connection  with the  transfer of the Property to Borrower  have been paid.  All
mortgage, mortgage recording, stamp, intangible or other similar tax required to
be paid by any Person under applicable Legal Requirements currently in effect in
connection  with the execution,  delivery,  recordation,  filing,  registration,
perfection or enforcement of any of the Loan Documents,  including the Mortgage,
have  been  paid  and,  under  current  Legal  Requirements,   the  Mortgage  is
enforceable  against  Borrower in accordance with its respective terms by Lender
(or any subsequent holder thereof), except as such enforceability may be limited
by  insolvency,  bankruptcy,  moratorium  or  other  laws  affecting  creditor's
remedies in general and principles of equity.

     (dd)  Single-Purpose.  Borrower  hereby  represents  and  warrants  to, and
covenants  with,  Lender that,  as of the date hereof and until such time as the

          party  or  Guarantor,  except  upon  terms  and  conditions  that  are
          intrinsically  fair and  substantially  similar to those that would be
          available on an  arms-length  basis with third  parties other than any
          such party.

     (iv) Borrower  has  not  incurred,   and  Borrower  will  not  incur,   any
          indebtedness,  secured or unsecured,  direct or indirect,  absolute or
          contingent  (including  guaranteeing any  obligation),  other than the
          Permitted  Indebtedness.  Except  as  set  forth  in  the  immediately
          preceding sentence, no indebtedness other than the Debt may be secured
          (subordinate or pari passu) by the Property.

          company formalities, as the case may be, and preserve its existence.

     (viii) Borrower  will not permit any  constituent  party or  Guarantor  to,
          amend,  modify  or  otherwise  change  the  partnership   certificate,

          operating agreement or other  organizational  documents of Borrower or

          stationery, invoices and checks.

     (ee) Investment Company Act. Borrower is not (i) an "investment company" or
a company  "controlled"  by an "investment  company,"  within the meaning of the
Investment  Company  Act of 1940,  as  amended;  (ii) a "holding  company"  or a
"subsidiary  company"  of a  "holding  company"  or an  "affiliate"  of either a
"holding  company" or a  "subsidiary  company"  within the meaning of the Public
Utility Holding  Company Act of 1935, as amended;  or (iii) subject to any other
federal or state law or  regulation  which  purports to restrict or regulate its
ability to borrow money.

     (ff)  Fraudulent  Transfer.  Borrower  has not entered into the Loan or any
Loan Document with the actual intent to hinder,  delay, or defraud any creditor,
and  Borrower  has  received  reasonably  equivalent  value in exchange  for its
obligations  under  the  Loan  Documents.  Giving  effect  to  the  transactions
contemplated by the Loan Documents, the fair saleable value of Borrower's assets
exceeds and will,  immediately  following the execution and delivery of the Loan
Documents,   exceed  Borrower's  total  liabilities,   including   subordinated,
unliquidated,  disputed or contingent  liabilities.  The fair saleable  value of
Borrower's assets is and will,  immediately following the execution and delivery
of  the  Loan  Documents,  be  greater  than  Borrower's  probable  liabilities,
including the maximum amount of its contingent  liabilities or its debts as such
debts become  absolute and matured.  Borrower's  assets do not and,  immediately
following the execution and delivery of the Loan Documents will not,  constitute
unreasonably small capital to carry out its business as conducted or as proposed
to be conducted. Borrower does not intend to, and does not believe that it will,
incur  debts  and  liabilities   (including  contingent  liabilities  and  other
commitments)  beyond its ability to pay such debts as they mature  (taking  into
account the timing and amounts to be payable on or in respect of  obligations of
Borrower).

     (gg) Management  Agreement.  The Management  Agreement is in full force and
effect and there is no default,  breach or violation existing  thereunder by any
party  thereto and no event has  occurred  (other than  payments due but not yet
delinquent)  that,  with the  passage of time or the giving of notice,  or both,
would constitute a default, breach or violation by any party thereunder. Neither
the  execution  and  delivery  of the  Loan  Documents,  Borrower's  performance
thereunder, the recordation of the Mortgage, nor the exercise of any remedies by
Lender, will adversely affect Borrower's rights under the Management Agreement.

     Section 4.2 SURVIVAL OF  REPRESENTATIONS.  Borrower  agrees that all of the
representations  and  warranties  of  Borrower  set  forth  in  Section  4.1 and
elsewhere in this Agreement and in the other Loan Documents shall survive for so
long as any amount  remains  owing to Lender under this  Agreement or any of the
other Loan Documents by Borrower. All representations, warranties, covenants and
agreements  made in this  Agreement  or in the other Loan  Documents by Borrower
shall  be  deemed  to have  been  relied  upon  by  Lender  notwithstanding  any
investigation heretofore or hereafter made by Lender or on its behalf.

V.   AFFIRMATIVE COVENANTS
     ---------------------

     Section 5.1 BORROWER COVENANTS.  From the date hereof and until payment and
performance  in full of all  obligations of Borrower under the Loan Documents or
the earlier release of the Lien of the Mortgage (and all related obligations) in
accordance  with the  terms of this  Agreement  and the  other  Loan  Documents,
Borrower hereby covenants and agrees with Lender that:

     (a) Existence;  Compliance  with Legal  Requirements;  Insurance.  Borrower
shall do or cause to be done all things necessary to preserve, renew and keep in
full force and effect its existence,  rights,  licenses,  permits and franchises
and  comply  with all  Legal  Requirements  applicable  to it and the  Property.
Borrower  shall at all times  maintain,  preserve and protect all franchises and
trade names and preserve all the remainder of its property used or useful in the
conduct of its business  and shall keep the  Property in good working  order and
repair,  and  from  time to time  make,  or cause  to be  made,  all  reasonably
necessary repairs, renewals, replacements, betterments and improvements thereto,
all as more fully provided in the Mortgage.
                                      -22-
<PAGE>
     (b) Taxes and Other Charges. Borrower shall pay all Taxes and Other Charges
now or hereafter  levied or assessed or imposed against the Property or any part
thereof  as the same  become  due and  payable,  other  than  those  which it is
protesting  in good  faith by  appropriate  proceedings  diligently  pursued  in
accordance  with this  Section.  Borrower  will  deliver to Lender  receipts for
payment  or other  evidence  satisfactory  to  Lender  that the  Taxes and Other
Charges have been so paid or are not then  delinquent  no later than thirty (30)
days prior to the date on which the Taxes and/or Other Charges  would  otherwise
be delinquent if not paid (provided,  however,  that Borrower is not required to
furnish  such  receipts for payment of Taxes in the event that such Taxes are to
be paid by Lender pursuant to Section 7.3 hereof if Borrower furnishes a request
by such date for a disbursement from the Tax and Insurance Escrow Fund and there
are sufficient funds therein to make the payment). Borrower shall not suffer and
when due shall  cause to be paid and  discharged  any lien or charge  whatsoever
which may be or become a lien or charge  against the Property  (other than those
liens or charges  which  Borrower  is  protesting  in good faith by  appropriate
proceedings,  diligently  pursued),  and  when  due  shall  pay for all  utility
services  provided  to the  Property.  After  prior  written  notice to  Lender,
Borrower,  at its own  expense,  may contest by  appropriate  legal  proceeding,
promptly  initiated  and  conducted  in good faith and with due  diligence,  the
amount  or  validity  or  application  in whole or in part of any Taxes or Other
Charges,  provided  that (i) no  Default or Event of Default  has  occurred  and
remains uncured,  (ii) such proceeding shall suspend the collection of the Taxes
or Other Charges from the  Property,  (iii) such  proceeding  shall be permitted
under and be conducted in accordance with the provisions of any other instrument
to which Borrower is subject and shall not constitute a default thereunder, (iv)
neither the Property nor any part thereof or interest  therein will be in danger
of being sold, forfeited,  terminated, canceled or lost, (v) Borrower shall have
furnished  such  security  as may be required  in the  proceeding,  or as may be
reasonably requested by Lender, to insure the payment of any such Taxes or Other
Charges,  together  with all interest and  penalties  thereon and (vi)  Borrower
shall promptly upon final determination thereof pay the amount of any such Taxes
or Other Charges,  together with all costs,  interest and penalties which may be
payable in  connection  therewith  subject to payment  pursuant to Section  7.3.
Lender may,  following prior written notice to Borrower,  pay over any such cash
deposit or part thereof held by Lender to the claimant  entitled  thereto at any
time when,  in the  judgment  of Lender,  the  entitlement  of such  claimant is
established.

     (c) Litigation.  Borrower shall give prompt written notice to Lender of any
litigation or governmental  proceedings  pending or threatened  against Borrower
which might  materially  adversely  affect  Borrower's  condition  (financial or
otherwise) or business or the Property.

     (d) Premises.  Borrower shall permit agents,  representatives and employees
of Lender to inspect the Property or any part thereof at  reasonable  hours upon
reasonable advance notice.

     (e)  Notice  of  Default.  Borrower  shall  promptly  advise  Lender of any
material adverse change in Borrower's condition,  financial or otherwise,  or of
the  occurrence  of any  Default  or Event of  Default  of  which  Borrower  has
knowledge.

     (f) Cooperate in Legal  Proceedings.  Borrower shall  cooperate  fully with
Lender  with  respect  to any  proceedings  before  any  court,  board  or other
Governmental  Authority  which may in any way  materially  adversely  affect the
rights of Lender  hereunder  or any rights  obtained by Lender  under any of the
other Loan  Documents  and,  in  connection  therewith,  permit  Lender,  at its
election, to participate in any such proceedings.

     (g) Perform Loan Documents. Borrower shall observe, perform and satisfy all
the terms,  provisions,  covenants and conditions of, and shall pay when due all
costs,  fees and  expenses  to the  extent  required  under  the Loan  Documents
executed and delivered by Borrower.

     (h) Insurance  Benefits.  Borrower shall cooperate with Lender in obtaining
for Lender the benefits of any Insurance  Proceeds lawfully or equitably payable
in  accordance  with Section 7.1 hereof in  connection  with the  Property,  and
Lender shall be reimbursed  for any expenses  incurred in  connection  therewith
(including attorneys' fees and disbursements, and the expense of an appraisal on
behalf of Lender in case of a fire or other  casualty  affecting the Property or
any part thereof) out of such Insurance Proceeds.

     (i)  Further  Assurances.  Borrower  shall,  at  Borrower's  sole  cost and
expense:



                                      -23-
<PAGE>
          (A) furnish to Lender all instruments,  documents,  boundary  surveys,
footing  or  foundation   surveys,   certificates,   plans  and  specifications,
appraisals, title and other insurance reports and agreements, and each and every
other document,  certificate,  agreement and instrument required to be furnished
by it pursuant to the terms of the Loan  Documents  or  reasonably  requested by
Lender in connection therewith;

          (B)  execute  and  deliver  to  Lender  such  documents,  instruments,
certificates,  assignments and other writings,  and do such other acts necessary
or desirable,  to evidence,  preserve  and/or protect the collateral at any time
securing or  intended to secure its  obligations  under the Loan  Documents,  as
Lender may reasonably require, so long as Borrower's liability is not materially
increased thereby; and

          (C) do and execute all and such further  lawful and  reasonable  acts,
conveyances and assurances for the better and more effective carrying out of the
intents and purposes of this Agreement and the other Loan  Documents,  as Lender
shall reasonably  require from time to time, so long as Borrower's  liability is
not materially increased thereby.

     (j)  Supplemental  Mortgage  Affidavits.  If at any time Lender  reasonably
determines,  based on  applicable  law,  that Lender is not being  afforded  the
maximum  amount of security  available from the Property as a direct or indirect
result of  applicable  taxes not having been paid with respect to the  Property,
Borrower  agrees that Borrower will execute,  acknowledge and deliver to Lender,
immediately upon Lender's request, supplemental affidavits increasing the amount
of the Debt  attributable to the Property to the amount of the Debt and Borrower
shall, on demand, pay any additional taxes.

     (k) Financial Reporting.

          (i)  Borrower  will  keep and  maintain  or will  cause to be kept and
maintained on a Fiscal Year basis,  in accordance with GAAP or another method of
preparation approved by Lender,  proper and accurate books, records and accounts
reflecting all of the financial  affairs of Borrower and all items of income and
expense in connection  with the operation of the Property and in connection with
any services, equipment or furnishings provided in connection with the operation
of the  Property,  whether  such income or expense be realized by Borrower or by
any other Person  whatsoever,  excepting  lessees  unrelated to and unaffiliated
with  Borrower  who have leased from  Borrower  portions of the Property for the
purpose of occupying the same.  Lender shall have the right from time to time at
all times during normal  business hours upon  reasonable  notice to examine such
books,  records  and  accounts  at  the  office  of  Borrower  or  other  Person
maintaining such books, records and accounts and to make such copies or extracts
thereof as Lender shall desire.  After the occurrence and during the continuance
of an Event of Default,  Borrower  shall pay any costs and expenses  incurred by
Lender to examine Borrower's accounting records with respect to the Property, as
Lender  shall  determine to be necessary or  appropriate  in the  protection  of
Lender's interest.

          (ii) Borrower will furnish to Lender  annually,  (A) within forty (40)
days  following  the end of each Fiscal Year of  Borrower,  unaudited  financial
statements  of Borrower,  and (B) within  ninety (90) days  following the end of
each  Fiscal  Year  of  Borrower,   (y)  a  complete  copy  of  the  unqualified
consolidated annual financial statements of Prime Group Realty Trust, audited by
a "big six" accounting firm (as such accounting firm may have been  consolidated
with another "big six" accounting firm) or another independent  certified public
accountant  reasonably acceptable to Lender in accordance with GAAP covering the
Property  for  such  Fiscal  Year  and (z)  financial  statements  of  Borrower,
unaudited but certified by an independent certified public accountant reasonably
acceptable to Lender,  containing  balance  sheets and  statements of profit and
loss for  Borrower  and the  Property  in such  detail as Lender may  reasonably
request.  Such statements shall set forth the financial condition and the income
and  expenses  for the  Property for the  immediately  preceding  calendar  year
including statements of annual net operating income. Borrower's annual financial
statements  (unaudited  and  audited)  shall  be  accompanied  by  an  Officer's
Certificate certifying that, to the best of such officer's knowledge,  each such
annual  financial  statement  presents  fairly the  financial  condition  of the
Property and has been prepared in accordance with GAAP. Together with Borrower's
annual  financial  statements,  Borrower  shall  furnish to Lender an  Officer's
Certificate  certifying  as of the  date  thereof  whether,  to the  best of its
knowledge,  there exists an event or circumstance which constitutes a Default or
Event of Default  under the Loan  Documents  executed and delivered by Borrower,
and if such Default or Event of Default exists,  the nature thereof,  the period
of time it has existed and the action then being taken to remedy the same.



                                      -24-

          (iii) Borrower will furnish, or cause to be furnished, to Lender on or
before  thirty  (30) days  after the end of each  calendar  month the  following
items, in a format reasonably acceptable to Lender,  accompanied by an Officer's

are true,  correct,  accurate,  and  complete and fairly  present the  financial
condition  and  results  of the  operations  of  Borrower  and the  Property  in
accordance  with GAAP or a method of preparation  approved by Lender (subject to
normal  year  end  adjustments)  as  applicable:  (A)  monthly  and year to date
operating  statements  prepared for each  calendar  month,  noting net operating
income and other  information  necessary and sufficient to fairly  represent the
results of operation of the Property  during such  calendar  month,  all in form
reasonably  satisfactory to Lender; (B) a balance sheet for each such month; (C)
a  comparison  of the budgeted  income and  expenses  and the actual  income and
expenses  for  each  month  and year to date for the  Property  together  with a
detailed  explanation  of any  variances  of ten percent  (10%) or more  between
budgeted and actual amounts for such period and year to date; (D) a statement of
the actual capital expenditures made by Borrower during each calendar quarter as
of the last day of such  calendar  quarter;  (E) a  calculation  reflecting  the

certificate.

          (iv)  Borrower will  furnish,  or cause to be furnished,  to Lender as
soon as available  and in any event on or before  thirty (30) days after the end
of each calendar  month  occupancy  rates,  rent rolls  (identifying  the leased
premises,  names of all  tenants,  units  leased,  monthly  rental and all other
charges  payable under each lease,  date to which paid,  term of lease,  date of
occupancy,  date  of  expiration,  any and  every  material  special  provision,
concession or inducement granted to tenants during such month) and a delinquency
report for the Property and such other relevant  information with respect to the
Property as requested by the Lender,  in each case  accompanied  by an Officer's
Certificate  certifying  that  such  items  are  true,  correct,  accurate,  and
complete.

          (v) Borrower  shall  furnish to Lender,  within ten (10) Business Days
after request,  such further detailed  information with respect to the operation
of the  Property  and the  financial  affairs of Borrower  as may be  reasonably
requested  by Lender or any  applicable  Rating  Agency.  If  Borrower  fails to
provide to Lender or its designee any of the financial statements, certificates,
reports or information (the "Required  Records") required by this Section 5.1(k)
within thirty (30) days after the date upon which such  Required  Record is due,
Borrower shall pay to Lender, at Lender's option and in its sole discretion,  an
amount equal to $5,000 for each Required Record that is not delivered;  provided
that,  Lender  has given at least  fifteen  (15) days  prior  written  notice to
Borrower of such failure by Borrower to timely  submit the  applicable  Required
Record.

     (l)  Business  and  Operations.  Borrower  will  continue  to engage in the
businesses presently conducted by it as and to the extent the same are necessary
for the  ownership,  maintenance,  management  and  operation  of the  Property.

laws of each  jurisdiction  as and to the extent the same are  required  for the
ownership, maintenance, management and operation of the Property.

     (m) Title to the  Property.  Borrower will warrant and defend (i) the title

the Loan Documents (including Permitted  Encumbrances) and (ii) the validity and
priority of the Lien of the Mortgage,  subject only to Liens permitted under the
Loan  Documents  (including  Permitted  Encumbrances),  in each case against the
claims of all  Persons  whomsoever.  Borrower  shall  reimburse  Lender  for any
losses,  costs,  damages or expenses (including  reasonable  attorneys' fees and
court costs)  incurred by Lender if an interest in the  Property,  other than as
permitted hereunder, is claimed by another Person.

     (n) Costs of Enforcement.  In the event (i) that the Mortgage is foreclosed
in  whole or in part or is put into the  hands of an  attorney  for  collection,
suit, action or foreclosure, (ii) of the foreclosure of any mortgage prior to or
subsequent to the Mortgage  encumbering the Property in which proceeding  Lender
is made a party or (iii) of the bankruptcy, insolvency,  rehabilitation or other
similar  proceeding  in respect of Borrower or an assignment by Borrower for the
benefit  of its  creditors,  Borrower,  its  successors  or  assigns,  shall  be
chargeable with and agrees to pay all costs of collection and defense, including
reasonable  attorneys'  fees in connection  therewith and in connection with any
appellate  proceeding or post-judgment  action involved therein,  which shall be

     (o) Estoppel Statement.
                                      -25-
<PAGE>
          (i) After  request  by  Lender,  Borrower  shall  within ten (10) days
furnish Lender with a statement, duly acknowledged and certified,  setting forth
(A) the unpaid  principal amount of the Note, (B) the Interest Rate of the Note,
(C) the date  installments of interest and/or  principal were last paid, (D) any
offsets or defenses  to the  payment of the Debt,  if any and (E) that the Note,
this Agreement,  the Mortgage and the other Loan Documents are valid,  legal and
binding  obligations  and  have  not  been  modified  or  if  modified,   giving
particulars of such modification.

          (ii) After request by Lender (but no more  frequently than once in any
year),  Borrower  shall within ten (10) days furnish  Lender with a  certificate
reaffirming all  representations and warranties of Borrower set forth herein and
in the other Loan Documents as of the date requested by Lender or, to the extent
of any  changes to any such  representations  and  warranties,  so stating  such
changes.

          (iii) Borrower shall deliver to Lender upon request,  tenant  estoppel
certificates  from each tenant at the Property in form and substance  reasonably
satisfactory  to Lender  provided that Borrower shall not be required to deliver
such certificates more frequently than one (1) time in any calendar year.

     (p) Loan Proceeds.  Borrower shall use the proceeds of the Loan received by
it on the Closing Date only for the purposes set forth in Section 2.1.4.

     (q)  Performance by Borrower.  Borrower  shall in a timely manner  observe,
perform and fulfill  each and every  covenant,  term and  provision of each Loan
Document  executed  and  delivered  by  Borrower,  and shall  not enter  into or
otherwise  suffer or permit any amendment,  waiver,  supplement,  termination or
other  modification  of any Loan  Document  executed  and  delivered by Borrower
without the prior written consent of Lender.

     (r) Annual  Budget.  Borrower  shall  prepare  and  submit (or shall  cause
Manager to prepare  and  submit) to Lender by December 1 of each year during the
Term, a proposed pro forma  budget for the  Property for the  succeeding  fiscal
year  commencing  January 1 and ending  December 31 (the "Annual  Budget")  and,
promptly after  preparation  thereof,  any  subsequent  revisions to such Annual
Budget.  After the  occurrence of a Cash Trap Event,  the Annual Budget shall be
subject to Lender's  approval which approval shall not be unreasonably  withheld
or  delayed.  Lender's  failure  to  approve or  disapprove  any  Annual  Budget
requiring  Lender's  approval  within  thirty (30) days after  Lender's  receipt
thereof  shall be deemed to constitute  Lender's  approval  thereof.  The Annual
Budget shall consist of (i) an operating expense budget (the "Operating Budget")
showing, on a month-by-month  basis, in reasonable detail, each line item of the
Borrower's anticipated income and Operating Expenses (on a cash modified basis),
including amounts required to establish, maintain and/or increase reserves, (ii)
a Capital Expense Budget (the "Capital  Budget")  showing,  on a  month-by-month
basis, in reasonable detail, each line item of anticipated  Capital Expenses.  A
copy of the Budget for the period  commencing  on the date  hereof and ending on
December  31,  1998  shall  be  delivered  to  Lender  for its  approval  within
forty-five (45) days after the date hereof.

     (s) Confirmation of  Representations.  In addition to and not in limitation
of the covenants and agreements of Borrower  contained in Section 9.1,  Borrower
shall  deliver,  in  connection  with  any  Secondary  Market  Transaction,  (i)
Officer's Certificates certifying as to the accuracy of all representations made
by Borrower in the Loan Documents (with changes made to such  representations as
necessary  to render them  factually  accurate) as of the date of the closing of
such  Secondary  Market  Transaction  and  (ii)  certificates  of  the  relevant
Governmental  Authorities  in all  relevant  jurisdictions  indicating  the good
standing and  qualification  of Borrower as of the date of the Secondary  Market
Transaction.

     (t) No Joint Assessment.  Borrower shall not suffer, permit or initiate the
joint assessment of the Property (i) with any other real property constituting a
tax lot  separate  from the  Property  and (ii) with any portion of the Property
which may be deemed to  constitute  personal  property,  or any other  procedure
whereby the lien of any taxes which may be levied against such personal property
shall be assessed or levied or charged to the Property.

     (u) Leasing  Matters.  Borrower shall not,  without  Lender's prior written
consent,  enter  into,  modify,  amend or renew any Lease (x) for 10,000 or more
square feet while an Event of Default is not occurring or (y) for any size while
an Event of Default is  continuing.  Any Lease for less than 10,000  square feet
that is entered into, modified,  amended or renewed during a period of time when
no Event of Default  exists shall be deemed  approved by Lender  (such Lease,  a
"Deemed  Approved  Lease").  If Lender  does not approve or  disapprove  a Lease


                                      -26-
<PAGE>
(other than a Deemed  Approved  Lease) within ten (10) Business Days of Lender's
receipt of such Lease and all information  relating thereto reasonably requested
by Lender,  such Lease shall be deemed  approved.  Upon request,  Borrower shall
furnish  Lender with executed  copies of all Leases.  All renewals of Leases and
all proposed  Leases shall  provide for rental rates that are at or greater than
existing local market rates for space at properties similar to the Property. All
proposed Leases shall be on commercially  reasonable terms and shall not contain
any terms which would materially adversely affect Lender's rights under the Loan
Documents.  All Leases shall provide that they are  subordinate  to the Mortgage
encumbering  the Property  and that the lessee  agrees to attorn to Lender if it
succeeds to the interest of Borrower in the Property. Borrower (i) shall observe
and perform the obligations imposed upon the lessor under the Leases, other than
immaterial  obligations  the failure of which to perform is not likely to have a
material adverse effect on the Property or the applicable Lease(s);  (ii) shall,
in the exercise of its prudent business judgment,  enforce the terms,  covenants
and conditions contained in the Leases upon the part of the lessee thereunder to
be observed or performed; (iii) shall not collect any of the rents more than one
(1) month in advance (other than security deposits);  (iv) shall not execute any
other  assignment  of lessor's  interest  in the Leases or the Rents  (except as
contemplated by the Loan Documents);  (v) shall not alter,  modify or change the
terms of the Leases in a manner  inconsistent  within the provisions of the Loan
Documents;  and (vi) shall execute and deliver at the request of Lender all such
further assurances,  confirmations and assignments in connection with the Leases
as Lender shall from time to time reasonably require.

     (v) Principal  Place of Business.  Borrower  shall not change its principal
place of business set forth on the first page of this  Agreement  without  first
giving Lender thirty (30) days prior written notice.

     (w) Management Agreement.  Borrower shall cause the Property to be operated
pursuant the Management Agreement. Borrower shall:

          (i)  promptly   perform  and/or  observe  all  of  the  covenants  and
agreements  required to be  performed  and  observed by it under the  Management
Agreement  and do all things  necessary to preserve and to keep  unimpaired  its
material rights thereunder;

          (ii)  promptly  notify  Lender of any  default  under  the  Management
Agreement of which it is aware;

          (iii)  promptly,  upon Lender's  request,  deliver to Lender a copy of
each financial  statement,  business plan, capital  expenditures plan,  property
improvement plan and any other notice,  report and estimate received by it under
the Management Agreement; and

          (iv) promptly  enforce the  performance  and  observance of all of the
covenants and agreements required to be performed and/or observed by the Manager
under the Management Agreement.

VI.      NEGATIVE COVENANTS
        ------------------

     Section 6.1  BORROWER'S  NEGATIVE  COVENANTS.  From the date  hereof  until
payment and  performance  in full of all  obligations of Borrower under the Loan
Documents or the earlier  release of the Lien of the Mortgage in accordance with
the terms of this Agreement and the other Loan Documents, Borrower covenants and
agrees  with  Lender that it will not do,  directly  or  indirectly,  any of the
following:

     (a)  Operation of Property.  Borrower  shall not,  without  Lender's  prior
consent:  (i)  surrender,  terminate  or  cancel  the  Management  Agreement  or
otherwise replace the Manager of the Property or enter into any other management
agreements with respect to the Property  (except  pursuant to Section 9.5); (ii)
reduce or  consent to the  reduction  of the term of the  Management  Agreement;
(iii) increase or consent to the increase of the amount of any charges under the
Management Agreement;  or (iv) otherwise modify,  change,  supplement,  alter or
amend,  or waive or release any of its rights and remedies  under the Management
Agreement in any material respect.

     (b) Liens. Borrower shall not, without the prior written consent of Lender,
create, incur, assume or suffer to exist any Lien on any portion of the Property
or permit any such action to be taken, except (i) Permitted  Encumbrances,  (ii)
Liens created by or permitted pursuant to the Loan Documents and (iii) Liens for
Taxes or Other Charges not yet due.

     (d) Change In Business.  Borrower shall not enter into any line of business
other than the ownership  and  operation of the  Property,  or make any material
change  in  the  scope  or  nature  of  its  business  objectives,  purposes  or
operations, or undertake or participate in activities other than the continuance
of its present business.

     (e) Debt  Cancellation.  Borrower shall not cancel or otherwise  forgive or
release any claim or debt owed to Borrower  by any Person,  except for  adequate
consideration  and  in  the  ordinary  course  of  Borrower's  business  in  its
reasonable judgment.

     (f) Affiliate  Transactions.  Borrower  shall not enter into, or be a party
to, any  transaction  with an  Affiliate  of  Borrower  or any of the members of
Borrower  except in the ordinary course of business and on terms which are fully
disclosed  to Lender in advance  and are no less  favorable  to Borrower or such
Affiliate than would be obtained in a comparable arms-length transaction with an
unrelated third party.

     (g)  Zoning.   Borrower  shall  not  initiate  or  consent  to  any  zoning
reclassification  of any  portion of any of the  Property  or seek any  variance
under any existing  zoning  ordinance or use or permit the use of any portion of
any of the  Property  in any  manner  that could  result in such use  becoming a
non-conforming  use under any zoning  ordinance or any other applicable land use
law, rule or regulation, without the prior consent of Lender.

     (h) Assets.  Borrower shall not purchase or own any real  properties  other
than the Property.

     (i) Debt.  Borrower shall not create,  incur or assume any debt  (including
subordinate debt) other than the Debt and other than Permitted Indebtedness.  In
addition,  no Person owning any interest in Borrower  shall pledge,  transfer or
otherwise  dispose of its interest in Borrower to secure any  financing  for the
benefit of such Person, Borrower or the Property.

     (j)  Transfers.  Borrower shall not,  without the prior written  consent of
Lender,  suffer  or permit  the  sale,  assignment  or  transfer  (collectively,
"Transfer")  of (i) all or any  part of the  Property  (except  pursuant  to any
Lease)  other  than in  connection  with a  Special  Transfer,  (ii) any  direct
interest in  Borrower or (iii) any direct or indirect  interest in any member of
Borrower  other than (A) the  issuance or transfer of  beneficial  interests  in
Prime Group Realty Trust, a Maryland real estate  investment  trust,  so long as
such  issuance or transfer does not result in a change in Control of Prime Group
Realty  Trust and so long as such  issuance  or  transfer  does not  affect  the
non-consolidation  opinion  delivered  by  Borrower,  and  (B) the  issuance  or
transfer of limited  partner  interests  in Prime Group  Realty L.P., a Delaware
limited  partnership,  or a  conversion  of a one  percent  general  partnership
interest owned  beneficially  by The Nardi Group,  L.L.C.  in Prime Group Realty
L.P. into a limited partnership  interest in Prime Group Realty L.P., so long as
such  issuance or transfer does not result in a change in Control of Prime Group
Realty  L.P.  and so long as such  issuance  or  transfer  does not  affect  the
non-consolidation  opinion  delivered  by  Borrower;   provided,  however,  that
Borrower may grant the easements  and other rights in the Property  specifically
permitted under Section 8(f) of the Mortgage. No Transfer consented to by Lender
pursuant to clause (ii) or (iii) above shall be  permitted  unless  Lender shall
have received (a) evidence in writing from the applicable Rating Agencies to the
effect that such a Transfer  will not result in a  qualification,  withdrawal or
downgrading of the ratings in effect  immediately prior to such Transfer for the
Securities  issued  in  connection  with  the  Securitization   which  are  then
outstanding and (b) a non-consolidation  opinion satisfactory to Lender from the
transferee's  counsel.  On or  before  the  completion  of  any  such  permitted
Transfer,  Borrower  will pay all  reasonable  expenses  of Lender  incurred  in
connection therewith. Notwithstanding anything to the contrary contained in this
clause (j),  holders of  interests  in Borrower  (or holders of interests in any
entity  directly or  indirectly  holding an interest in Borrower) as of the date
hereof (the "Interest  Holders") shall have the right to transfer their interest
in  Borrower  (or any entity  directly  or  indirectly  holding an  interest  in
Borrower) to another  Person who is not an Interest  Holder,  including  without
limitation  immediate  family  members  for estate  planning  purposes,  without
Lender's consent; provided, however, that:

          (i) after  taking into  account any prior  transfers  pursuant to this
sentence,  whether to the proposed transferee or otherwise, no such transfer (or
series of transfers) shall result in (A) the proposed transferee,  together with
all members of his/her immediate family or any affiliates thereof, owning in the
aggregate (directly,  indirectly or beneficially) more than 20% of the interests
in  Borrower  (or any entity  directly  or  indirectly  holding an  interest  in
Borrower) or (B) a transfer in the  aggregate of more than 20% of the  interests
in Borrower as of the date hereof;
                                      -28-
<PAGE>
          (ii) no such transfer of interest  shall result in a change of control
of Borrower or the day-to-day operations of the Property;

          (iii) Borrower shall give Lender notice of such transfer together with
copies of all  instruments  effecting  such transfer not less than ten (10) days
prior to the date of such transfer;

          (iv) no Event of Default has occurred and remains uncured; and

          (v) the legal and financial  structure of Borrower after such transfer
and its members  and the single  purpose  nature and  bankruptcy  remoteness  of
Borrower  and its  shareholders,  partners or members  satisfies  Lender's  then
current  applicable  underwriting  criteria and requirements,  including without
limitation  the  requirement  at  the  request  of  Lender  to  deliver  written
confirmations from the Rating Agencies that such transfer or series of transfers
will  not  result  in a  qualification,  downgrade  or  withdrawal  of the  then
applicable ratings.

For  purposes of this clause (j),  (A) a change of control of Borrower  shall be
deemed to have occurred if there is any change in the identity of the individual
or entities or group of individuals or entities who have the right, by virtue of
any  partnership  agreement,  articles  of  incorporation,  bylaws,  articles of
organization, operating agreement or any other agreement, with or without taking
any  formative  action,  to cause  Borrower  to take some  action or to prevent,
restrict or impede  Borrower  from taking some  action  which,  in either  case,
Borrower  could take or could  refrain from taking were it not for the rights of
such individuals;  and (B) an "immediate family member" shall mean a spouse or a
child of any Interest Holder.

     Section 7.1 INSURANCE; CASUALTY AND CONDEMNATION.

     7.1.1 INSURANCE.

     (a)  Borrower,  at its sole cost and  expense,  for the  mutual  benefit of
Borrower  and Lender,  shall keep the  Property  insured and obtain and maintain
during  the Term  policies  of  insurance  insuring  against  loss or  damage by
standard,  "all-risk" perils.  Such insurance (i) shall be in an amount equal to
the  greatest  of (A) the then full  replacement  cost of the  Property  without
deduction for physical  depreciation,  (B) the outstanding  principal balance of
the  Loan  and (C) such  amount  that the  insurer  would  not deem  Borrower  a
co-insurer  under said policies and (ii) and shall have  deductibles  no greater

premiums  for such  policies  of  insurance  carried  in  accordance  with  this
paragraph  shall be paid  annually in advance and shall  contain a  "Replacement
Cost Endorsement" with a waiver of depreciation.

     (b)  Borrower,  at its sole cost and  expense,  for the  mutual  benefit of
Borrower  and  Lender,  shall  also  obtain  and  maintain  during  the Term the
following policies of insurance:

          (i) Flood  insurance if any part of the Property is located in an area
identified by the Federal Emergency  Management Agency as an area having special
flood  hazards and in which flood  insurance has been made  available  under the
National Flood Insurance  Program in an amount at least equal to the Debt or the
maximum  limit of coverage  available  with respect to the  Property  under said
program, whichever is less.

          (ii)  Commercial  general  liability  insurance,  including broad form
property  damage,  blanket  contractual and personal  injuries  (including death
resulting  therefrom)  coverages and containing minimum limits per occurrence of

least $10,000,000 excess and/or umbrella  liability  insurance shall be obtained

upon  Borrower and all court costs and  attorneys'  fees  incurred in connection
with the ownership, operation and maintenance of the Property.

          (iii) Rental loss and/or business interruption  insurance in an amount
equal to the greater of (A) the estimated  gross revenues from the operations of
the  Property  for the next  succeeding  eighteen  (18) month  period or (B) the
projected  operating  expenses  (including Debt Service) for the maintenance and
operation of the Property for the next  succeeding  eighteen  (18) month period.
The amount of such  insurance  shall be  increased  from time to time during the
Term as and when the Rents  increase or the  estimate  of (or the actual)  gross
revenue, as may be applicable, increases.

                                      -29-
<PAGE>
          (iv)  Insurance  against  loss or damage from (A) leakage of sprinkler
systems and (B) explosion of steam boilers,  air  conditioning  equipment,  high
pressure piping, machinery and equipment,  pressure vessels or similar apparatus

explosions), in an amount at least equal to $2,000,000 for the Property.

          (v) Worker's  compensation  insurance with respect to any employees of
Borrower, as required by any governmental authority or legal requirement.

          (vi) During any period of repair or restoration,  builder's "all risk"
insurance  in an amount equal to not less than the full  insurable  value of the
Property against such risks  (including fire and extended  coverage and collapse
of the  Improvements  to agreed  limits)  as  Lender  may  request,  in form and
substance acceptable to Lender.

          (vii)  Coverage  to  compensate  for the  cost of  demolition  and the
increased cost of  construction  for the Property in an amount  satisfactory  to
Lender.

          (viii)  Such other  insurance  as may from time to time be  reasonably
required by Lender in order to protect its interests.

     (c) All policies of insurance (the "Policies") required pursuant to Section
7.1.1(b) shall be issued by companies reasonably approved by Lender and licensed
to do  business  in the State,  with a claims  paying  ability  rating of "A" or
better by  Standard & Poor's  Ratings  Group;  (ii)  shall  name  Lender and its
successors  and/or assigns as their interest may appear as the mortgagee;  (iii)
shall  contain a  Non-Contributory  Standard  Lender  Clause and a Lender's Loss
Payable Endorsement, or their equivalents,  naming Lender as the person to which
all payments made by such insurance  company shall be paid; (iv) shall contain a
waiver of subrogation  against  Lender;  (v) shall be maintained  throughout the
Term without cost to Lender; (vi) shall be assigned and the certificates thereof
delivered to Lender; and (vii) shall contain endorsements providing that neither
Borrower,  Lender nor any other party shall be a co-insurer  under said Policies
and that Lender shall receive at least thirty (30) days prior written  notice of
any modification,  reduction or cancellation of any of the Policies;  and (viii)
shall be  satisfactory  in form and substance to Lender and shall be approved by
Lender  as to  amounts,  form,  risk  coverage,  deductibles,  loss  payees  and
insureds.  Borrower  shall pay the premiums for such  Policies  (the  "Insurance
Premiums")  as the same  become  due and  payable  and shall  furnish  to Lender
evidence of the renewal of each of the Policies with receipts for the payment of
the Insurance Premiums or other evidence of such payment reasonably satisfactory
to Lender  (provided,  however,  that  Borrower is not  required to furnish such
evidence  of  payment  to Lender if such  Insurance  Premiums  have been paid by
Lender  pursuant  to Section 7.3  hereof).  If  Borrower  does not furnish  such
evidence  and  receipts  at least ten (10) days prior to the  expiration  of any
expiring Policy, then Lender may procure, but shall not be obligated to procure,
such insurance and pay the Insurance Premiums  therefor,  and Borrower agrees to
reimburse  Lender for the cost of such  Insurance  Premiums  promptly on demand.
Within  thirty (30) days after  request by Lender,  Borrower  shall  obtain such
increases in the amounts of coverage  required  hereunder  as may be  reasonably
requested  by Lender,  taking into  consideration  changes in the value of money
over time,  changes in  liability  laws,  and  changes  in prudent  customs  and
practices.

     (d) If any Property is damaged or  destroyed,  in whole or in part, by fire
or other  casualty (an "Insured  Casualty"),  Borrower  shall give prompt notice
thereof to Lender.  Following the occurrence of an Insured Casualty,  unless the
Loan is repaid in full,  Borrower  shall  promptly  proceed to restore,  repair,
replace  or  rebuild  the  Property  to  be of  at  least  equal  value  and  of
substantially the same character as prior to such damage or destruction,  all to
be effected in  accordance  with Legal  Requirements.  The expenses  incurred by
Lender in the adjustment and collection of insurance  proceeds shall become part
of the Debt and be secured  hereby and shall be reimbursed by Borrower to Lender
upon demand.

     7.1.2 CASUALTY AND APPLICATION OF PROCEEDS.

     (a) In  case  of  loss  or  damages  covered  by any of the  Policies,  the
following provisions shall apply:

          (i) If an Insured  Casualty  does not exceed  $200,000,  Borrower  may
settle and adjust any claim  without the consent of Lender;  provided  that such
adjustment  is  carried  out in a  competent  and timely  manner.  In such case,
Borrower is hereby  authorized  to collect  and  receipt for any such  insurance
proceeds.


                                      -30-
<PAGE>
          (ii) If an Insured Casualty shall equal or exceed $200,000, Lender may
settle and adjust any claim  without the consent of Borrower  and agree with the
insurance  company or  companies  on the amount to be paid on the loss,  and the
proceeds of any such policy  shall be due and payable  solely to Lender and held
in escrow by Lender in accordance with the terms hereof.

     (b) In the event of an Insured  Casualty  where the loss is in an aggregate
amount less than $2,000,000,  and if, in the reasonable  judgment of Lender, the
Property  can be  restored  within  six (6)  months  and  prior to the  Optional
Prepayment  Date to an economic  unit not less valuable and not less useful than
the same was prior to the  Insured  Casualty,  and after such  restoration  will
adequately  secure the Debt,  then, if no Default or Event of Default shall have
occurred and be then continuing,  the proceeds of insurance (after reimbursement
of any expenses  incurred by Lender) shall be applied to reimburse  Borrower for
the cost of restoring,  repairing,  replacing or rebuilding the Property or part
thereof subject to the Insured Casualty (the  "Restoration"),  in the manner set
forth herein.  Borrower  hereby  covenants and agrees to commence and diligently
prosecute such Restoration;  provided that (i) Borrower shall pay all costs (and
if required by Lender,  Borrower  shall deposit the total thereof with Lender in
advance) of such  Restoration  in excess of the net proceeds of  insurance  made
available  pursuant to the terms hereof;  (ii) the Restoration  shall be done in
compliance  with all Legal  Requirements;  and (iii) Lender shall have  received
evidence  reasonably   satisfactory  to  it  that,  during  the  period  of  the
Restoration,  the sum of (A) income  derived from the  Property,  as  reasonably
determined  by Lender,  plus (B)  proceeds  of rent loss  insurance  or business
interruption  insurance,  if any, to be paid will equal or exceed the sum of (I)
expenses in  connection  with the  operation  of the  Property and (II) the Debt
Service under the Loan.

     (c) Except as provided above, the proceeds of insurance  collected upon any
Insured  Casualty  shall,  at the  option of Lender in its sole  discretion,  be
applied to the payment of the Debt or applied to reimburse Borrower for the cost
of any  Restoration,  in the manner set forth below. Any such application to the
Debt shall be without any  prepayment  consideration  except that if an Event of
Default has occurred and is continuing  at the time the  insurance  proceeds are
received,  then Borrower  shall pay to Lender an additional  amount equal to the
Yield  Maintenance  Premium,  if any, that would be required under Section 2.3.3
hereof if a Defeasance Deposit was to be made by Borrower.  Any such application
to the Debt shall be applied to those  payments of principal  and interest  last
due under  the Note but shall not  postpone  or reduce  any  payments  otherwise
required pursuant to the Note other than such last due payments.

     (d) If Borrower is entitled to reimbursement out of insurance proceeds held
by   Lender,   such   proceeds   shall  be   deposited   by   Lender   into  the
Casualty/Condemnation Subaccount (as described in the Cash Collateral Agreement)
and disbursed from time to time from the  Casualty/Condemnation  Subaccount upon
Lender being  furnished  with (i) evidence  satisfactory  to it of the estimated
cost of  completion  of the  Restoration,  (ii)  funds or, at  Lender's  option,
assurances  satisfactory to Lender that such funds are available,  sufficient in
addition to the proceeds of  insurance  to complete  the  proposed  Restoration,
(iii)  such  architect's  certificates,  waivers  of  lien,  contractor's  sworn
statements, title insurance endorsements,  bonds, plats of survey and such other
evidences of cost,  payment and performance as Lender may reasonably require and
approve and (iv) all plans and specifications  for such Restoration,  such plans
and  specifications  to be approved by Lender prior to commencement of any work.
In addition,  no payment made prior to the final  completion of the  Restoration
shall exceed ninety  percent (90%) of the value of the work  performed from time
to time;  funds other than  proceeds of insurance  shall be  disbursed  prior to
disbursement of such proceeds; and at all times, the undisbursed balance of such
proceeds  remaining in the hands of Lender,  together  with funds  deposited for
that purpose or  irrevocably  committed to the  satisfaction  of Lender by or on
behalf  of  Borrower  for that  purpose,  shall be at  least  sufficient  in the
reasonable  judgment  of  Lender  to pay  for  the  cost  of  completion  of the
Restoration,  free and clear of all liens or claims for lien.  Any surplus which
may remain out of insurance  proceeds held by Lender after payment of such costs
of Restoration shall be paid to Borrower.

     7.1.3 Condemnation.

     (a) Borrower  shall  promptly give Lender  written  notice of the actual or
threatened  commencement  of  any  condemnation  or  eminent  domain  proceeding
affecting the Property (a "Condemnation")  and shall deliver to Lender copies of
any and all papers served in connection  with such  Condemnation.  Following the
occurrence  of a  Condemnation,  Borrower,  regardless  of  whether  an Award is
available,  shall promptly  proceed to restore,  repair,  replace or rebuild the
Property  to  the  extent  practicable  to be of at  least  equal  value  and of
substantially  the  same  character  as prior  to such  Condemnation,  all to be
effected in accordance with Legal Requirements.
                                      -31-
<PAGE>
     (b) Lender is hereby irrevocably appointed as Borrower's  attorney-in-fact,
coupled with an interest,  with exclusive  power to collect,  receive and retain
any award or payment in respect of a  Condemnation  (an "Award") and to make any
compromise or settlement in connection  with such  Condemnation,  subject to the
provisions of this Section.  Notwithstanding  any  Condemnation by any public or
quasi-public   authority   (including  any  transfer  made  in  lieu  of  or  in
anticipation of such a Condemnation), Borrower shall continue to pay the Debt at
the time and in the manner  provided for in the Note, in this  Agreement and the
other Loan  Documents  and the Debt  shall not be  reduced  unless and until any
Award  shall have been  actually  received  and applied by Lender to expenses of
collecting  the Award and to discharge of the Debt.  Lender shall not be limited
to the  interest  paid on the  Award by the  condemning  authority  but shall be
entitled to receive out of the Award  interest at the rate or rates  provided in
the Note.  Borrower shall cause any Award that is payable to Borrower to be paid
directly to Lender.

     (c) In the event of any  Condemnation  where  the Award is in an  aggregate
amount less than $2,000,000,  and if, in the reasonable  judgment of Lender, the
Property  can be  restored  within  six (6)  months  and  prior to the  Optional
Prepayment  Date to an economic  unit not less valuable and not less useful than
the  same  was  prior to the  Condemnation,  and  after  such  restoration  will
adequately  secure the Debt,  then, if no Default or Event of Default shall have
occurred and be then continuing,  the proceeds of the Award (after reimbursement
of any expenses  incurred by Lender) shall be applied to reimburse  Borrower for
the cost of restoring,  repairing,  replacing or rebuilding the Property or part
thereof subject to Condemnation (the  "Condemnation  Restoration") in the manner
set forth below. Borrower hereby covenants and agrees to commence and diligently
to prosecute such Condemnation Restoration; provided that (i) Borrower shall pay
all costs (and if required by Lender,  Borrower  shall deposit the total thereof
with Lender in advance) of such Condemnation  Restoration in excess of the Award
made available pursuant to the terms hereof;  (ii) the Condemnation  Restoration
shall be done in compliance with all Legal Requirements;  and (iii) Lender shall
have received evidence reasonably  satisfactory to it that, during the period of
the Condemnation  Restoration,  the sum of (A) income derived from the Property,
as reasonably  determined by Lender, plus (B) proceeds of rent loss insurance or
business interruption insurance, if any, to be paid will equal or exceed the sum
of (I) expenses in  connection  with the  operation of the Property and (II) the
Debt Service under the Loan.

     (d) Except as provided  above,  the Award  collected upon any  Condemnation
shall, at the option of Lender in its sole discretion, be applied to the payment
of the Debt or applied to reimburse  Borrower  for the cost of the  Condemnation
Restoration  in the manner set forth  below.  Any such  application  to the Debt
shall be without any prepayment consideration except that if an Event of Default
has occurred and is continuing at the time the Award is received,  then Borrower
shall pay to Lender an additional amount equal to the Yield Maintenance Premium,
if any,  that would be  required  under  Section  2.3.3  hereof if a  Defeasance
Deposit was to be made by Borrower.  Any such  application  to the Debt shall be
applied to those  payments of principal and interest last due under the Note but
shall not postpone or reduce any  payments  otherwise  required  pursuant to the
Note  other  than such  last due  payments.  If the  Property  is sold,  through
foreclosure or otherwise,  prior to the receipt by Lender of such Award,  Lender
shall have the right,  whether or not a deficiency judgment on the Note shall be
recoverable or shall have been sought,  recovered or denied, to receive all or a
portion of said Award sufficient to pay the Debt.

     (e) In the event  Borrower is entitled  to  reimbursement  out of the Award
received by Lender,  such  proceeds  shall be  disbursed  from time to time upon
Lender being  furnished  with (i) evidence  satisfactory  to it of the estimated
cost of completion of the Condemnation  Restoration,  (ii) funds or, at Lender's
option,  assurances  satisfactory  to  Lender  that such  funds  are  available,
sufficient in addition to the proceeds of the Award to complete the Condemnation
Restoration, (iii) such architect's certificates,  waivers of lien, contractor's
sworn statements, title insurance endorsements,  bonds, plats of survey and such
other  evidences  of costs,  payment and  performance  as Lender may  reasonably
require and approve; and (iv) all plans and specifications for such Condemnation
Restoration,  such plans and  specifications  to be approved by Lender  prior to
commencement of work. In addition, no payment made prior to the final completion
of the  restoration,  repair,  replacement  and  rebuilding  shall exceed ninety
percent (90%) of the value of the work  performed  from time to time;  (y) funds
other than  proceeds of the Award shall be disbursed  prior to  disbursement  of
such proceeds;  and (z) at all times,  the undisbursed  balance of such proceeds
remaining in the hands of Lender, together with funds deposited for that purpose
or  irrevocably  committed  to the  satisfaction  of  Lender  by or on behalf of
Borrower  for  that  purpose,  shall be at least  sufficient  in the  reasonable
judgment  of  Lender  to pay for the  costs of  completion  of the  Condemnation


                                      -32-
<PAGE>
Restoration  free and clear of all liens or claims for lien.  Any surplus  which
may remain out of the Award  received by Lender  after  payment of such costs of
restoration,  repair,  replacement or rebuilding shall, in the sole and absolute
discretion of Lender, be retained by Lender and applied to payment of the Debt.

     Section 7.2 REQUIRED REPAIR; REQUIRED REPAIR FUNDS.

     7.2.1 REQUIRED REPAIRS: DEPOSITS. Borrower shall perform the repairs at the
Property  set forth on  Schedule  3 annexed  hereto  (the  "Required  Repairs").
Borrower shall  complete each of the Required  Repairs on or before the deadline
for same set forth on Schedule 3. On the Closing  Date,  Borrower  shall deposit
with Lender the amount set forth on  Schedule 3 hereto to perform  the  Required
Repairs for the Property. Amounts so deposited with Lender (the "Required Repair
Fund") shall be held by Lender in an account (the "Required  Repair Account") in
Lender's  name  at a  financial  institution  selected  by  Lender  in its  sole
discretion and shall be invested in Permitted Investments.

     7.2.2 GRANT OF SECURITY  INTEREST.  Borrower  hereby  pledges,  assigns and
grants a security interest to Lender, as security for payment of all sums due in
respect  of the Loan and the  performance  of all other  terms,  conditions  and
covenants of the Loan Documents and this Agreement on Borrower's part to be paid
and  performed,  all of  Borrower's  right,  title  and  interest  in and to the
Required  Repair  Fund and the  Required  Repair  Account.  Borrower  shall not,
without obtaining the prior written consent of Lender, further pledge, assign or
grant any security  interest in the Required  Repair Fund or the Required Repair
Account or permit any lien or encumbrance to attach  thereto,  or any levy to be
made thereon, or any UCC-l Financing  Statements,  except those naming Lender as
the secured party, to be filed with respect thereto.

     7.2.3 RELEASE OF REQUIRED  REPAIR FUNDS.  Lender shall disburse to Borrower
all Required  Repair Funds in the Required  Repair Account upon  satisfaction by
Borrower  of each of the  following  conditions:  (a)  Borrower  shall  submit a
written  request  for  payment to Lender at least  thirty (30) days prior to the
date on which  Borrower  requests such payment be made (except in the case of an
emergency repair which requires immediate attention, in which event Borrower may
submit such payment request within ten (10) days),  (b) on the date such request
is  received by Lender and on the date such  payment is to be made,  no Event of
Default  shall  exist and remain  uncured,  (c) Lender  shall have  received  an
Officer's  Certificate from Borrower certifying that all Required Repairs at the
Property for which  disbursement has been requested have been completed (i) in a

<PAGE>
     7.3.1 TAX AND INSURANCE  ESCROW FUND.  Borrower  shall pay to Lender (a) on
each Payment Date, (i)  one-twelfth  (1/12) of the Taxes that Lender  reasonably
estimates will be payable during the next ensuing twelve (12) months in order to
accumulate  with Lender  sufficient  funds to pay all such Taxes at least thirty
(30) days prior to their respective due dates and (ii) one-twelfth (1/12) of the
Insurance  Premiums that Lender estimates will be payable for the renewal of the
coverage  afforded  by the  Policies  upon the  expiration  thereof  in order to
accumulate with Lender  sufficient  funds to pay all such Insurance  Premiums at
least  thirty (30) days prior to the  expiration  of the Policies and (b) on the
Closing Date, an amount which, when combined with the monthly deposits described
in (a) above,  shall be sufficient to pay the next  installment of Taxes and the
next  required  payment of  Insurance  Premiums on the due date  therefor  (said
amounts in (a) and (b) above  hereinafter  called the "Tax and Insurance  Escrow
Fund").  The Tax and  Insurance  Escrow  Fund,  and the  payments of interest or
principal or both,  payable  pursuant to the Note,  shall be added  together and
shall be paid as an aggregate  sum by Borrower to Lender.  Lender will apply the
Tax and  Insurance  Escrow  Fund to  payments  of Taxes and  Insurance  Premiums
required  to be made by  Borrower  pursuant  to Section 5.1 hereof and under the
Mortgage,  or to  reimburse  Borrower  for such  amounts  upon  presentation  of
evidence  of  payment  and  an  Officer's  Certificate  in  form  and  substance
satisfactory to Lender;  subject,  however, to Borrower's right to contest Taxes
in accordance with Section 5.1(b) hereof.  In making any payment relating to the
Tax and Insurance Escrow Fund, Lender may do so according to any bill, statement
or estimate procured from the appropriate  public office (with respect to Taxes)
or insurer or agent (with respect to Insurance  Premiums),  without inquiry into
the  accuracy of such bill,  statement  or estimate or into the  validity of any
tax, assessment,  sale,  forfeiture,  tax lien or title or claim thereof. If the
amount of the Tax and  Insurance  Escrow  Fund shall  exceed the amounts due for
Taxes and Insurance Premiums pursuant to Section 5.1 hereof, Lender shall return
any excess to Borrower or credit such excess against future  payments to be made
to the Tax and Insurance Escrow Fund. In allocating such excess, Lender may deal
with the Person shown on the records of Lender to be the owner of the  Property.
If at any time Lender  determines that the Tax and Insurance  Escrow Fund is not
or will not be  sufficient  to pay the  items  set  forth in (a) and (b)  above,
Lender shall notify Borrower of such  determination  and Borrower shall increase
its monthly payments to Lender by the amount that Lender reasonably estimates is
sufficient  to make up the  deficiency  at  least  thirty  (30)  days  prior  to
delinquency of the Taxes and/or expiration of the Policies, as the case may be.

     7.3.2 GRANT OF SECURITY  INTEREST.  Borrower  hereby  pledges,  assigns and
grants a security  interest to Lender,  as security  for payment of all sums due
under the Loan and the performance of all other terms, conditions and provisions
of the Loan  Documents  and this  Agreement  on  Borrower's  part to be paid and
performed,  of all  Borrower's  right,  title and interest in and to the Tax and
Insurance Escrow Fund.  Borrower shall not, without  obtaining the prior written
consent of Lender,  further pledge, assign or grant any security interest in the
Tax and  Insurance  Escrow  Fund,  or permit any lien or  encumbrance  to attach
thereto,  or any levy to be made  thereon,  or any UCC-1  Financing  Statements,
except  those  naming  Lender as the  secured  party,  to be filed with  respect
thereto.

     7.3.3 APPLICATION OF TAX AND INSURANCE ESCROW FUND. Upon the occurrence and
during the  continuance  of an Event of Default,  Lender may apply any sums then
present in the Tax and  Insurance  Escrow Fund to the  payment of the  following
items in any order in its sole  discretion:  (a) Taxes  and Other  Charges;  (b)
Insurance  Premiums;  (c) interest on the unpaid principal  balance of the Note;
(d) amortization of the unpaid  principal  balance of the Note; or (e) all other
sums payable  pursuant to this Agreement and the other Loan  Documents.  The Tax
and  Insurance  Escrow  Fund  shall  not  constitute  a  trust  fund  and may be
commingled  with  other  monies  held by Lender.  Sums in the Tax and  Insurance
Escrow  Fund  shall  be held by  Lender  in an  account  in  Lender's  name at a
financial  institution  selected by Lender in its sole  discretion  and shall be
invested in Permitted  Investments.  Earnings or interest, if any, thereon shall
be retained as part of such funds and applied in  accordance  with this  Section
7.3.  Lender shall not be liable for any loss sustained on the investment of any
funds constituting the Tax and Insurance Escrow Fund.

     Section 7.4 CAPITAL RESERVE FUND.

     7.4.1 CAPITAL  RESERVE FUND.  Borrower  shall pay to Lender on each Payment
Date an  amount  equal  to  one-twelfth  (1/12th)  of the  product  obtained  by
multiplying  $0.27 by the aggregate  amount of square feet of rentable  space in
the Property  (said  amounts  hereinafter  called the "Capital  Reserve  Fund").
Lender  will apply the  Capital  Reserve  Fund to payment  of  Approved  Capital
Expenses pursuant to the terms hereof; provided, however, if the Loan shall have
been  accelerated or if there is an Event of Default which is  continuing,  then


                                      -34-
<PAGE>
Lender may credit such Capital  Reserve  Fund against the Debt in such  priority
and proportions as Lender in its sole and absolute discretion shall deem proper.
If the amount of the  Capital  Reserve  Fund shall  exceed the  amounts  due for
Approved  Capital  Expenses  pursuant to the terms hereof,  Lender shall, in its
discretion,  return any excess to Borrower  or, if future  Capital  Reserve Fund
payments are then  required,  credit such excess  against such future  payments;
provided,  however,  if the Loan shall have been  accelerated  or if there is an
Event of Default which is continuing, then Lender may credit such excess against
the Debt in such  priority  and  proportions  as Lender in its sole and absolute
discretion shall deem proper.

     7.4.2 GRANT OF SECURITY  INTEREST.  Borrower  hereby pledges and assigns to
Lender,  and grants to Lender a security interest in all Borrower's right, title
and interest in and to the Capital  Reserve Fund, as security for payment of all
sums due under the Loan and the  performance of all other terms,  conditions and
provisions  of the Loan  Documents and this  Agreement on Borrower's  part to be
paid and  performed.  Borrower  shall not,  without  obtaining the prior written
consent of Lender,  further pledge, assign or grant any security interest in the
Capital  Reserve Fund, or permit any lien or encumbrance to attach  thereto,  or
any levy to be made thereon,  or any UCC-1  Financing  Statements,  except those
naming  Lender as the secured  party,  to be filed with  respect  thereto.  This
Agreement  is,  among  other  things,  intended  by the parties to be a security
agreement for purposes of the Illinois Uniform Commercial Code.

     7.4.3  APPLICATION OF CAPITAL  RESERVE FUND. Upon the occurrence and during
the  continuance of an Event of Default,  Lender may apply any sums then present

principal  balance of the Note; (c) amortization of the unpaid principal balance
of the Note;  or (d) all other sums payable  pursuant to this  Agreement and the
other Loan Documents. The Capital Reserve Fund shall not constitute a trust fund
and may be  commingled  with other  monies  held by Lender.  Sums in the Capital
Reserve  Fund  shall be held by  Lender  in an  account  in  Lender's  name at a
financial  institution  selected by Lender in its sole  discretion  and shall be
invested in Permitted  Investments.  Earnings or interest, if any, thereon shall
be retained as part of such funds and applied in  accordance  with this  Section
7.4.  Lender shall not be liable for any loss sustained on the investment of any
funds constituting the Capital Reserve Fund.

     7.4.4 PAYMENT OF CAPITAL  EXPENSES.  Funds held in the Capital Reserve Fund
may be used for Approved Capital Expenses.  From time to time, Borrower may send
a request for  disbursement  of funds in the Capital  Reserve Fund, but not more
than one (1) time per  month  and,  to the  extent  there are  sufficient  funds
available  in the Capital  Reserve  Fund,  such  disbursements  shall be made by
Lender so long as (a) no Event of Default shall have occurred and be continuing;
(b) such expenditure is for an Approved Capital Expense; and (c) the request for
disbursement is accompanied by (i) an Officer's  Certificate  certifying (A) the
amount  of  funds  to be  disbursed,  (B) that  such  funds  will be used to pay
Approved Capital Expenses and a description  thereof,  (C) that the same has not

     Section 7.5 ROLLOVER RESERVE FUND.

     7.5.1 ROLLOVER RESERVE FUND.

     (a) Borrower shall pay to Lender on each Payment Date commencing January 1,

                  (i) if the unsecured  debt rating of Prime Group Realty Trust,

         Prime Group Guaranty (as defined below);

                  (ii)  Borrower  shall  not be  required  to make any  Rollover

         and

                                      -35-

                  (iii)  Borrower  shall not be  required  to make any  Rollover
         Payments if Borrower  delivers to Lender, on or before January 1, 2000,
         an irrevocable  letter of credit in the amount of $429,799.00 in a form
         and issued by a bank reasonably  acceptable to Lender, and Lender shall

         Lender from Prime  Group  Realty,  L.P.,  pursuant to which Prime Group
         Realty,  L.P.  unconditionally  guarantees the payment of all costs and
         expenses, up to a maximum amount of $429,799.00, incurred in connection
         with Approved Leasing Expenses.  Lender shall have the right to enforce

         for application of funds deposited in the Rollover Reserve Fund.

     (b) Lender will apply the Rollover  Reserve Fund to the payment of Approved
Leasing Expenses pursuant to the terms of this Section 7.5;  provided,  however,
if there is an Event of Default which is continuing, then Lender may credit such
Rollover  Reserve Fund  against the Debt in such  priority  and  proportions  as
Lender in its sole and absolute  discretion shall deem proper.  If the amount of
the Rollover  Reserve  Fund shall  exceed the amounts due for  Approved  Leasing
Expenses  pursuant  to  the  terms  hereof,  Lender  shall,  in  its  reasonable
discretion,  return any excess to Borrower;  provided,  however,  if there is an

entitled to make partial draw  requests on said letter of credit for the amounts
so requested by Borrower and shall disburse such amounts in accordance  with the

permitted under said letter of credit then,  upon  Borrower's  first request for
disbursement of Rollover Reserve Fund sums, Lender shall make a draw request for
the full  amount  of the  letter  of credit  and  shall  hold such  funds in the
Rollover  Reserve Fund and disburse such funds in  accordance  with this Section
7.5.

     Section  7.6  PAYMENT OF  APPROVED  OPERATING  EXPENSES.  After a Cash Trap
Event,  Funds  held in the Cash  Collateral  Account  may be used  for  Approved
Operating Expenses, provided that such use shall be in Lender's discretion if an

has not occurred, Borrower may from time to time send a request for disbursement
of funds in the Cash  Collateral  Account  for  payment  of  Approved  Operating
Expenses,  but not more than one (1) time per  month.  To the  extent  there are
funds available in the Cash Collateral Account in excess of the amounts required
to fund the Tax and Insurance  Escrow Fund, the Capital  Reserve Fund and to pay
the Monthly Debt Service  Payment  Amount due in respect of the Loan on the next
Payment Date, such  disbursements for Approved  Operating Expenses shall be made

previous disbursement and (E) that all previous  disbursements have been or will

receives  from the Borrower a valid  request for a  disbursement  for payment of
Approved  Operating  Expenses  for the then  Current  Month  at  least  five (5)
Business Days prior to the Payment Date  occurring in such Current  Month,  then
the disbursement in respect of such Approved Operating Expenses shall be made to
Borrower on such Payment Date. If the Borrower  shall fail to validly  request a
disbursement  for payment of Approved  Operating  Expenses  for the then Current
Month at least five (5) Business  Days prior to the Payment Date in such Current
Month,  then the Lender shall  retain in the Deposit  Account an amount equal to
the  anticipated  Operating  Expenses for the then Current Month as set forth in
the approved  Operating Budget for such month, and the Lender shall,  subject to
satisfaction of the preceding conditions, disburse same to the Borrower five (5)
Business  Days  after the  Lender  receives a valid  request  therefor.  Amounts
disbursed to the  Borrower  under this Section 7.6 shall be used by the Borrower
to pay  current  Approved  Operating  Expenses  and for no  other  purpose.  The
Borrower  shall furnish the Lender with copies of bills,  statements,  invoices,

     (a) Upon the  occurrence of an Event of Default,  all or any one or more of
the rights,  powers,  privileges and other remedies  available to Lender against
Borrower under this  Agreement or any of the other Loan  Documents  executed and

                                      -38-
<PAGE>
delivered  by Borrower or at law or in equity may be  exercised by Lender at any
time  and  from  time to time,  whether  or not all or any of the Debt  shall be
declared due and payable,  and whether or not Lender  shall have  commenced  any
foreclosure  proceeding  or other action for the  enforcement  of its rights and
remedies under any of the Loan Documents with respect to the Property.  Any such
actions taken by Lender shall be cumulative  and  concurrent  and may be pursued
independently,  singly, successively, together or otherwise, at such time and in
such order as Lender may determine in its sole discretion, to the fullest extent
permitted by law, without impairing or otherwise  affecting the other rights and
remedies of Lender  permitted by law,  equity or contract or as set forth herein
or in  the  other  Loan  Documents.  Without  limiting  the  generality  of  the
foregoing,  Borrower agrees that if an Event of Default is continuing (i) Lender
is not subject to any "one action" or  "election  of  remedies"  law or rule and
(ii) all liens and other rights, remedies or privileges provided to Lender shall
remain in full force and effect until Lender has  exhausted  all of its remedies
against the Property and the Mortgage has been foreclosed, sold and/or otherwise
realized upon in satisfaction of the Debt or the Debt has been paid in full.

     (b) Lender  shall have the right from time to time to  partially  foreclose
the Mortgage in any manner and for any amounts  secured by the Mortgage then due
and payable as determined by Lender in its sole  discretion  including,  without
limitation,  the following circumstances:  (i) in the event Borrower defaults in
the payment of one or more scheduled payments of principal and interest,  Lender
may  foreclose the Mortgage to recover such  delinquent  payments or (ii) in the
event Lender elects to  accelerate  less than the entire  outstanding  principal
balance of the Loan, Lender may foreclose the Mortgage to recover so much of the
principal balance of the Loan as Lender may accelerate.  Notwithstanding  one or
more partial foreclosures,  the Property shall remain subject to the Mortgage to
secure payment of sums secured by the Mortgage and not previously recovered.

     (c) Lender shall have the right from time to time to sever the Note and the
other  Loan  Documents  into one or more  separate  notes,  mortgages  and other
security  documents in such  denominations as Lender shall determine in its sole
discretion  for purposes of  evidencing  and  enforcing  its rights and remedies
provided  hereunder.  Borrower  shall execute and deliver to Lender from time to
time, promptly after the request of Lender, a severance agreement and such other
documents as Lender shall request in order to effect the severance  described in
the preceding  sentence,  all in form and substance  reasonably  satisfactory to
Lender.  Borrower hereby absolutely and irrevocably  appoints Lender as its true
and lawful attorney, coupled with an interest, in its name and stead to make and
execute all documents necessary or desirable to effect the aforesaid  severance,
Borrower ratifying all that its said attorney shall do by virtue thereof.

     Section 8.3 REMEDIES CUMULATIVE.  The rights, powers and remedies of Lender
under this  Agreement  shall be cumulative and not exclusive of any other right,
power  or  remedy  which  Lender  may have  against  Borrower  pursuant  to this
Agreement  or the  other  Loan  Documents,  or  existing  at law or in equity or
otherwise.   Lender's  rights,  powers  and  remedies  may  be  pursued  singly,
concurrently  or  otherwise,  at such  time  and in such  order  as  Lender  may
determine  in Lender's  sole  discretion.  No delay or omission to exercise  any
remedy,  right or power  accruing upon an Event of Default shall impair any such
remedy,  right or power or shall be construed as a waiver thereof,  but any such
remedy, right or power may be exercised from time to time and as often as may be
deemed  expedient.  A waiver of one Default or Event of Default  with respect to
Borrower  shall not be  construed  to be a waiver of any  subsequent  Default or
Event of Default by Borrower or to impair any remedy,  right or power consequent
thereon.

IX.  SPECIAL PROVISIONS
     ------------------

     Section 9.1 SALE OF NOTE AND SECONDARY MARKET TRANSACTION.

     9.1.1 COOPERATION.  At Lender's request (to the extent not already required
to be provided by Borrower under this Agreement),  Borrower shall use reasonable
efforts to satisfy the market standards to which Lender  customarily  adheres or
which may be reasonably required in the marketplace or by the Rating Agencies in
connection  with one or more sales or assignments of the Note or  participations
therein  or  securitizations  of rated  single  or  multiclass  securities  (the
"Securities")  secured by or evidencing  ownership interests in the Note and the
Mortgage (each such sale,  assignment,  participation and/or  securitization,  a
"Secondary  Market  Transaction").   Without  limiting  the  generality  of  the
foregoing,  Borrower  shall,  at the  request of Lender in  connection  with any
Secondary Market Transaction, and so long as the Loan is still outstanding:




                                      -39-

     (a) (i) provide such  financial and other  information  with respect to the
Property, Borrower and its Affiliates,  Manager and any tenants of the Property,
(ii)  provide  business  plans and budgets  relating to the  Property  and (iii)
perform or permit or cause to be performed or  permitted  such site  inspection,
appraisals,  surveys,  market studies,  environmental reviews and reports (Phase
I's and,  if  appropriate,  Phase  II's),  engineering  reports  and  other  due
diligence  investigations of the Property,  as may be reasonably  requested from
time to  time  by  Lender  or the  Rating  Agencies  or as may be  necessary  or
appropriate in connection  with a Secondary  Market  Transaction or Exchange Act
requirements  (the items provided to Lender pursuant to this paragraph (a) being
called the "Provided  Information"),  together,  if customary,  with appropriate
verification of and/or consents to the Provided  Information  through letters of
auditors or opinions of counsel of  independent  attorneys  acceptable to Lender
and the Rating Agencies;

     (b)  at  Borrower's  expense,  cause  counsel  to  render  opinions  as  to
non-consolidation,  fraudulent  conveyance,  true sale and true contribution and
any other opinion customary in  securitization  transactions with respect to the
Property,  Borrower and its  Affiliates,  which  counsel and  opinions  shall be
reasonably satisfactory to Lender and the Rating Agencies;

     (c) make such  representations and warranties as of the closing date of any
Secondary Market Transaction with respect to the Property, Borrower and the Loan
Documents  as  are  customarily  provided  in  such  transactions  and as may be
reasonably  requested by Lender or the Rating  Agencies and consistent  with the
facts covered by such  representations  and warranties as they exist on the date
thereof,   including  the  representations  and  warranties  made  in  the  Loan
Documents;

     (d) provide current  certificates of good standing and  qualification  with
respect to Borrower from appropriate Governmental Authorities; and

     (e)  execute  such   amendments  to  the  Loan   Documents  and  Borrower's
organizational  documents,  enter into a lock-box  or similar  arrangement  with
respect  to the  Rents and  establish  and fund such  reserve  funds  (including
reserve  funds for  deferred  maintenance  and capital  improvements)  as may be
requested  by Lender or the Rating  Agencies or  otherwise to effect a Secondary
Market Transaction, provided that nothing contained in this subsection (e) shall
result in a material economic change in the transaction.

Borrower  shall pay all  reasonable  third party costs and expenses  incurred by
Lender in connection with a Secondary Market Transaction

     9.1.2 USE OF INFORMATION.  Borrower  understands that all or any portion of
the Provided  Information and the Required Records may be included in disclosure
documents  in  connection  with a  Secondary  Market  Transaction,  including  a
prospectus or private placement  memorandum (each, a "Disclosure  Document") and
may also be included in filings  with the  Securities  and  Exchange  Commission
pursuant to the Securities Act of 1933, as amended (the  "Securities  Act"),  or
the  Securities and Exchange Act of 1934, as amended (the  "Exchange  Act"),  or
provided  or  made  available  to  investors  or  prospective  investors  in the
Securities, the Rating Agencies, and service providers or other parties relating
to the Secondary Market  Transaction.  In the event that the Disclosure Document
is required to be revised,  Borrower shall cooperate with Lender in updating the
Provided  Information  or  Required  Records  for  inclusion  or  summary in the
Disclosure  Document or for other use reasonably  required in connection  with a
Secondary Market Transaction by providing all current information  pertaining to
Borrower,  Manager and the Property  necessary to keep the  Disclosure  Document
accurate  and complete in all material  respects  with respect to such  matters.
Such  disclosure  may  include  the  opinion or  judgment  of Lender or Servicer
concerning  the Provided  Information  or other matters  disclosed,  and despite
reasonable good faith efforts by Lender and/or  Servicer,  the disclosure may be
erroneous  or  incomplete.   Borrower  hereby  consents  to  any  and  all  such
disclosures of such information.

     9.1.3 BORROWER OBLIGATIONS  REGARDING DISCLOSURE  DOCUMENTS.  In connection
with a Disclosure Document, Borrower shall:

     (a) if requested by Lender,  certify in writing that Borrower has carefully
examined those portions of such Disclosure Document, pertaining to Borrower, the
Property,  the  Manager  and the  Loan,  including  applicable  portions  of the
sections  entitled  "Special  Considerations",  "Description  of the Mortgages",
"Description of the Mortgage Loans and Mortgaged Property",  "The Manager", "The
Borrower" and "Certain  Legal Aspects of the Mortgage  Loan",  and such portions
(and  portions of any other  sections  reasonably  requested  and  pertaining to
Borrower,  the  Property,  the  Manager or the Loan) do not  contain  any untrue


                                      -40-
<PAGE>
statement of a material fact or omit to state a material fact necessary in order
to make the statements made, in the light of the circumstances  under which they
were made, not misleading;

     (b)  indemnify (i) any  underwriter,  syndicate  member or placement  agent
(collectively,  the  "Underwriters")  retained by Lender or its issuing  company
affiliate (the "Issuer") in connection with a Secondary Market Transaction, (ii)
Lender  and  (iii)  the  Issuer  that is named  in the  Disclosure  Document  or
registration   statement   relating  to  a  Secondary  Market  Transaction  (the
"Registration  Statement"),  and  each of the  Issuer's  directors,  each of its
officers who have signed the  Registration  Statement  and each person or entity
who  controls  the Issuer or the Lender  within the meaning of Section 15 of the
Securities Act or Section 30 of the Exchange Act (collectively within (iii), the
"CCA Group"), and each of its directors and each person who controls each of the
Underwriters, within the meaning of Section 15 of the Securities Act and Section
20 of the Exchange Act (collectively,  the "Underwriter  Group") for any losses,
claims,  damages or liabilities  (the  "Liabilities")  to which Lender,  the CCA
Group or the Underwriter Group may become subject (including  reimbursing all of
them for any  legal or other  expenses  actually  incurred  in  connection  with
investigating or defending the Liabilities) insofar as the Liabilities arise out
of or are based upon any untrue  statement  or alleged  untrue  statement of any
material  fact  contained  in  any  of  the  Required  Records  or in any of the
applicable  portions of such sections of the Disclosure  Document  applicable to
Borrower,  Manager,  the Property or the Loan, or arise out of or are based upon
the omission or alleged omission to state therein a material fact required to be
stated in the applicable portions of such sections or necessary in order to make
the  statements  in the  applicable  portions  of such  sections in light of the
circumstances  under which they were made, not  misleading,  provided,  however,
that  Borrower  shall not be required to  indemnify  Lender for any  Liabilities
relating to untrue  statements or omissions which Borrower  identified to Lender
in writing at the time of Borrower's  examination of such  Disclosure  Document;
and

     (c) reimburse  any member of the CCA Group for any legal or other  expenses
reasonably incurred by such member in connection with investigating or defending
the  Liabilities.  Borrower's  Liability  under clause (a) or (b) above shall be
limited to Liabilities arising out of or based upon any such untrue statement or
omission  made  therein in  reliance  upon and in  conformity  with  information
furnished  to  Lender  by or on  behalf  of  Borrower  in  connection  with  the
preparation of those portions of the Disclosure Document pertaining to Borrower,
Manager,  the Property or the Loan or in connection with the underwriting of the
debt, including financial  statements of Borrower,  operating  statements,  rent
rolls and other Required  Records,  environmental  site  assessment  reports and
property condition reports with respect to the Property. The foregoing indemnity
will be in addition to any liability which Borrower may otherwise have.

     9.1.4 BORROWER  INDEMNITY  REGARDING  FILINGS.  In connection  with filings
under the Exchange Act, Borrower shall (i) indemnify  Lender,  the CCA Group and
the Underwriter Group for any Liabilities to which Lender,  the CCA Group or the
Underwriter  Group may become subject insofar as the Liabilities arise out of or
are  based  upon the  omission  or  alleged  omission  to state in the  Provided
Information  or Required  Records a material  fact  required to be stated in the
Provided  Information or Required Records in order to make the statements in the
Provided  Information or Required Records,  in light of the circumstances  under
which they were made not misleading and (ii) reimburse Lender,  the CCA Group or
the  Underwriter  Group for any legal or other  expenses  actually  incurred  by
Lender,  CCA Group or the  Underwriter  Group in  connection  with  defending or
investigating the Liabilities.

     9.1.5 INDEMNIFICATION  PROCEDURE.  Promptly after receipt by an indemnified
party under Section 9.1.3 or 9.1.4 of notice of the  commencement  of any action
for which a claim  for  indemnification  is to be made  against  Borrower,  such
indemnified party shall notify Borrower in writing of such commencement, but the
omission to so notify the Borrower will not relieve  Borrower from any liability
that it may have to any indemnified  party  hereunder  except to the extent that
failure to notify causes prejudice to Borrower.  In the event that any action is
brought  against  any  indemnified  party,  and  it  notifies  Borrower  of  the
commencement  thereof,  Borrower  will  be  entitled,  jointly  with  any  other
indemnifying  party, to participate therein and, to the extent that it (or they)
may elect by written notice  delivered to the  indemnified  party promptly after
receiving the aforesaid  notice of  commencement,  to assume the defense thereof
with counsel  satisfactory to such  indemnified  party in its discretion.  After
notice  from  Borrower  to such  indemnified  party  under this  Section  9.1.5,
Borrower shall not be responsible  for any legal or other expenses  subsequently
incurred by such indemnified  party in connection with the defense thereof other
than reasonable costs of investigation;  provided, however, if the defendants in


                                      -41-
<PAGE>
any  such  action  include  both  Borrower  and an  indemnified  party,  and any
indemnified  party  shall  have  reasonably  concluded  that there are any legal
defenses  available to it and/or other  indemnified  parties that are  different
from or additional to those available to Borrower, then the indemnified party or
parties  shall have the right to select  separate  counsel to assert  such legal
defenses and to otherwise participate in the defense of such action on behalf of
such indemnified party or parties. Borrower shall not be liable for the expenses
of more than one separate  counsel unless there are legal defenses  available to
it  that  are  different  from or  additional  to  those  available  to  another
indemnified party.

     9.1.6 CONTRIBUTION. In order to provide for just and equitable contribution
in circumstances in which the indemnity  agreement provided for in Section 9.1.3
or 9.1.4 is for any reason held to be unenforceable  by an indemnified  party in
respect of any  Liabilities (or action in respect  thereof)  referred to therein
which would otherwise be  indemnifiable  under Section 9.1.3 or 9.1.4,  Borrower
shall  contribute  to the amount paid or payable by the  indemnified  party as a
result of such Liabilities (or action in respect  thereof);  provided,  however,
that no Person  guilty of  fraudulent  misrepresentation  (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution  from any
Person not  guilty of such  fraudulent  misrepresentation.  In  determining  the
amount of  contribution  to which  the  respective  parties  are  entitled,  the
following  factors  shall be  considered:  (i) the CCA  Group's  and  Borrower's
relative knowledge and access to information  concerning the matter with respect
to which the claim was asserted; (ii) the opportunity to correct and prevent any
statement or omission; and (iii) any other equitable considerations  appropriate
in the  circumstances.  Lender  and  Borrower  hereby  agree  that it may not be
equitable if the amount of such  contribution were determined by pro rata or per
capita allocation.

     9.1.7  RATING  SURVEILLANCE.  Lender  will  retain the Rating  Agencies  to
provide rating  surveillance  services on  Securities.  The pro rata expenses of
such  surveillance  will  be  paid  for by  Borrower  based  on  the  applicable
percentage  of  such  expenses  determined  by  dividing  the  then  outstanding
Principal by the then  aggregate  outstanding  amount of the pool created in the
Secondary Market Transaction which includes the Loan.

     Section 9.2 RESERVED

     Section 9.3 RESERVED.

     Section 9.4 EXCULPATION.  Subject to the qualifications below, Lender shall
not enforce the liability and  obligation of Borrower to perform and observe the
obligations  contained in the Note,  this  Agreement,  the Mortgage or the other
Loan  Documents by any action or proceeding  wherein a money  judgment  shall be
sought against Borrower,  except that Lender may bring a foreclosure  action, an
action for specific performance or any other appropriate action or proceeding to
enable  Lender to enforce and realize  upon its  interest  under the Note,  this
Agreement,  the Mortgage and the other Loan Documents,  or in the Property,  the
Rents, or any other  collateral  given to Lender pursuant to the Loan Documents;
provided, however, that, except as specifically provided herein, any judgment in
any such action or proceeding shall be enforceable  against Borrower only to the
extent of  Borrower's  interest in the  Property,  in the Rents and in any other
collateral given to Lender,  and Lender,  by accepting the Note, this Agreement,
the  Mortgage  and the other Loan  Documents,  agrees that it shall not sue for,
seek or demand any deficiency  judgment  against  Borrower in any such action or
proceeding  under or by reason of or under or in connection  with the Note, this
Agreement,  the Mortgage or the other Loan  Documents.  The  provisions  of this
section shall not,  however,  (a) constitute a waiver,  release or impairment of
any obligation evidenced or secured by any of the Loan Documents; (b) impair the
right of Lender to name Borrower as a party  defendant in any action or suit for
foreclosure   and  sale  under  the   Mortgage;   (c)  affect  the  validity  or
enforceability of or any guaranty made in connection with the Loan or any of the
rights  and  remedies  of Lender  thereunder;  (d) impair the right of Lender to
obtain the  appointment of a receiver;  (e) impair the enforcement of any of the
Assignments of Leases;  (f) constitute a prohibition  against Lender  commencing
any other appropriate  action or proceeding in order for Lender to fully realize
the security  granted by the  Mortgage or to exercise  its remedies  against the
Property;  or (g)  constitute  a waiver of the right of  Lender to  enforce  the
liability and  obligation of Borrower,  by money  judgment or otherwise,  to the
extent of any loss, damage, cost, expense,  liability, claim or other obligation
incurred by Lender  (including  attorneys' fees and costs  reasonably  incurred)
arising out of or in connection with the following:

     (i) fraud or intentional  misrepresentation by Borrower or any guarantor in
connection with the Loan;

     (ii) the gross negligence or willful misconduct of Borrower;
                                      -42-
<PAGE>
     (iii)  the  breach  of any  provision  in that  certain  Environmental  and
Hazardous  Substance  Indemnification  Agreement of even date herewith  given by
Borrower to Lender or in the Mortgage concerning  environmental laws,  hazardous
substances and asbestos and any  indemnification  of Lender with respect thereto
in either document;

     (iv)  physical  waste of the  Property,  or the  removal or disposal of any
portion of the Property;

     (v) the  misapplication  or  conversion  by Borrower  of (A) any  insurance
proceeds paid by reason of any loss, damage or destruction to the Property,  (B)
any awards or other amounts  received in connection with the condemnation of all
or a portion of the Property, or (C) any Rents following an Event of Default;

     (vi) failure to pay charges for labor or  materials  or other  charges that
can create  liens on any portion of the  Property  unless  such  charges are the
subject of a bona fide  dispute in which  Borrower is  contesting  the amount or
validity thereof;

     (vii) any security  deposits  collected  with respect to the Property which
are not delivered to Lender upon a foreclosure of the Property or action in lieu
thereof,  except to the  extent  any such  security  deposits  were  applied  in
accordance  with the  terms and  conditions  of any of the  Leases  prior to the
occurrence of the Event of Default that gave rise to such  foreclosure or action
in lieu thereof; and

     (viii) Borrower's indemnification of Lender set forth in Section 9.2.

Notwithstanding  anything to the  contrary in this  Agreement or any of the Loan
Documents,  (x) Lender shall not be deemed to have waived any right which Lender
may have under Sections 506(a),  506(b),  1111(b) or any other provisions of the
U.S.  Bankruptcy Code to file a claim for the full amount of the Debt secured by
the Mortgage or to require that all  collateral  shall continue to secure all of
the Debt owing to Lender in accordance with the Loan Documents, and (y) the Debt
shall be fully  recourse  to  Borrower  in the event  that:  (aa) the first full
monthly  payment of principal and interest  under the Note is not paid when due;
(bb) Borrower  fails to permit  on-site  inspections  of the Property,  fails to
provide financial information,  fails to maintain its status as a single purpose
entity or fails to appoint a new  property  manager  upon the  request of Lender
after an Event of Default, each as required by, and in accordance with the terms
and  provisions  of, this Loan Agreement and the Mortgage (cc) Borrower fails to
obtain  Lender's  prior written  consent to any  subordinate  financing or other
voluntary lien encumbering the Property other than a Permitted  Encumbrance;  or
(dd) Borrower fails to obtain  Lender's prior written consent to any assignment,
transfer,  or conveyance of the Property or any interest  therein as required by
the Mortgage.

     Section 9.5  TERMINATION OF MANAGER.  If an Event of Default is continuing,
Borrower shall, at the request of Lender, terminate the Management Agreement and
replace the Manager  with a manager  approved by Lender on terms and  conditions
satisfactory  to  Lender.  In  the  event  that  Borrower  does  not  propose  a
replacement manager to Lender for its approval within fifteen (15) business days
after the Lender's  request that  Borrower do so, Lender may propose two or more
such property managers for Borrower's  consideration.  If Borrower then fails to
select and retain one of such  property  managers  within  fifteen (15) business
days  thereafter,  Lender shall have the right to select a property  manager for
the Property,  and to enter into a management agreement with such manager in the
name of Borrower.  Borrower hereby appoints Lender its  attorney-in-fact,  which
appointment  is coupled with an interest,  for the purpose of entering into such
management agreement. The management agreement entered into between Borrower and
any Manager shall be in form and substance reasonably acceptable to Lender.

     Section 9.6 RETENTION OF SERVICER.  Lender reserves the right to retain the
Servicer  to act as its agent  hereunder  with such  powers as are  specifically
delegated  to the  Servicer  by Lender,  whether  pursuant  to the terms of this
Agreement,  the Pooling and Servicing  Agreement or the Cash Collateral  Account
Agreement  or  otherwise,  together  with such  other  powers as are  reasonably
incidental  thereto.  Borrower shall pay any reasonable fees and expenses of the
Servicer in  connection  with a  Defeasance  of the Note,  release of  Property,
assumption or modification of the Loan or enforcement of the Loan Documents.

approve  or  disapprove  or  to  decide  whether   arrangements   or  terms  are
satisfactory  or not  satisfactory  shall  (except as is otherwise  specifically
herein  provided)  be in the sole  discretion  of Lender  and shall be final and

     Section 10.4 MODIFICATION,  WAIVER IN WRITING. No modification,  amendment,
extension, discharge,  termination or waiver of any provision of this Agreement,
or of the Note, or of any other Loan  Document,  nor consent to any departure by
Borrower therefrom,  shall in any event be effective unless the same shall be in
a writing signed by the party against whom enforcement is sought,  and then such
waiver or consent shall be effective only in the specific instance,  and for the
purpose,  for which given.  Except as otherwise  expressly  provided herein,  no

notice or demand in the same, similar or other circumstances.
     Section  10.5 DELAY NOT A WAIVER.  Neither any failure nor any delay on the
part of Lender in  insisting  upon strict  performance  of any term,  condition,
covenant or  agreement,  or  exercising  any right,  power,  remedy or privilege

instrument given as security  therefor,  shall operate as or constitute a waiver

future exercise, or the exercise of any other right, power, remedy or privilege.
In particular,  and not by way of limitation, by accepting payment after the due
date of any  amount  payable  under this  Agreement,  the Note or any other Loan
Document,  Lender shall not be deemed to have waived any right either to require
prompt payment when due of all other amounts due under this Agreement,  the Note
or the other  Loan  Documents,  or to  declare a default  for  failure to effect
prompt payment of any such other amount.

     Section 10.7 WAIVER OF TRIAL BY JURY.  BORROWER AND LENDER HEREBY AGREE NOT
TO ELECT A TRIAL BY JURY OF ANY ISSUE  TRIABLE  OF RIGHT BY JURY,  AND WAIVE ANY
RIGHT TO TRIAL BY JURY  FULLY TO THE  EXTENT  THAT ANY SUCH  RIGHT  SHALL NOW OR
HEREAFTER EXIST WITH REGARD TO THE LOAN DOCUMENTS, OR ANY CLAIM, COUNTERCLAIM OR
OTHER ACTION ARISING IN CONNECTION  THEREWITH.  THIS WAIVER OF RIGHT TO TRIAL BY


                                      -45-
<PAGE>
JURY IS GIVEN KNOWINGLY AND VOLUNTARILY BY BORROWER AND LENDER,  AND IS INTENDED
TO ENCOMPASS  INDIVIDUALLY EACH INSTANCE AND EACH ISSUE AS TO WHICH THE RIGHT TO
A TRIAL BY JURY WOULD  OTHERWISE  ACCRUE.  LENDER AND  BORROWER  ARE EACH HEREBY
AUTHORIZED  TO FILE A COPY OF THIS  PARAGRAPH IN ANY  PROCEEDING  AS  CONCLUSIVE
EVIDENCE OF THIS WAIVER.

     Section 10.8 HEADINGS. The Article and/or Section headings and the Table of
Contents in this Agreement are included herein for convenience of reference only
and shall not constitute a part of this Agreement for any other purpose.

     Section  10.9  SEVERABILITY.  Wherever  possible,  each  provision  of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid under  applicable law, such provision shall be ineffective to the extent
of such  prohibition or invalidity,  without  invalidating the remainder of such
provision or the remaining provisions of this Agreement.

     Section 10.10  PREFERENCES.  Lender shall have the continuing and exclusive
right to apply or reverse and  reapply  any and all  payments by Borrower to any
portion of the obligations of Borrower hereunder. To the extent Borrower makes a
payment or payments to Lender, which payment or proceeds or any part thereof are
subsequently invalidated,  declared to be fraudulent or preferential,  set aside
or  required  to be repaid to a trustee,  receiver  or any other party under any
bankruptcy  law, state or federal law, common law or equitable  cause,  then, to
the extent of such payment or proceeds  received,  the obligations  hereunder or
part  thereof  intended to be  satisfied  shall be revived and  continue in full
force and  effect,  as if such  payment or  proceeds  had not been  received  by
Lender.

     Section  10.11  WAIVER OF NOTICE.  Borrower  shall not be  entitled  to any
notices of any nature  whatsoever from Lender except with respect to matters for
which this  Agreement or the other Loan  Documents  specifically  and  expressly
provide for the giving of notice by Lender to Borrower  and except with  respect
to matters for which Borrower is not, pursuant to applicable Legal Requirements,
permitted  to waive the  giving  of  notice.  To the  extent  permitted  by law,
Borrower  hereby  expressly  waives the right to receive  any notice from Lender
with respect to any matter for which this  Agreement or the other Loan Documents
do not specifically and expressly  provide for the giving of notice by Lender to
Borrower.

     Section  10.12  REMEDIES  OF  BORROWER.  In  the  event  that  a  claim  or
adjudication is made that Lender or its agents,  including Servicer,  have acted
unreasonably  or  unreasonably  delayed acting in any case where by law or under
this Agreement or the other Loan  Documents,  Lender or such agent,  as the case
may be, has an obligation to act  reasonably or promptly,  Borrower  agrees that
neither  Lender  nor its  agents,  including  Servicer,  shall be liable for any
monetary damages, and Borrower's sole remedies shall be limited to commencing an
action seeking  injunctive  relief or declaratory  judgment.  The parties hereto
agree  that any  action or  proceeding  to  determine  whether  Lender has acted
reasonably shall be determined by an action seeking declaratory judgment.

     Section 10.13 EXPENSES; INDEMNITY.

     (a) Borrower covenants and agrees to reimburse Lender (or the holder of the
Loan,  as  applicable)  upon receipt of written  notice from such holder for all
reasonable  costs  and  expenses  (including   reasonable  attorneys'  fees  and
disbursements)  incurred  by  Lender  in  connection  with (i) the  preparation,
negotiation,  execution  and  delivery  of this  Agreement  and the  other  Loan
Documents  and the  consummation  of the  transactions  contemplated  hereby and
thereby and all the costs of  furnishing  all  opinions by counsel for  Borrower
(including  any  opinions  requested by Lender as to any legal  matters  arising
under this  Agreement or the other Loan Documents with respect to the Property);
(ii) Borrower's ongoing performance of and compliance with Borrower's respective
agreements  and  covenants  contained  in  this  Agreement  and the  other  Loan
Documents on its part to be performed or complied  with after the Closing  Date,
including confirming  compliance with environmental and insurance  requirements;
(iii)  Lender's  ongoing  performance  and  compliance  with all  agreements and
conditions  contained in this Agreement and the other Loan Documents on its part
to be performed or complied with after the Closing Date;  (iv) the  negotiation,
preparation, execution, delivery and administration of any consents, amendments,
waivers or other  modifications  to this  Agreement and the other Loan Documents
and any other documents or matters requested by Lender;  (v) Borrower  complying
with  any  requests  made  pursuant  to  Section  9.1  hereof  (subject  to  the
limitations  contained in such section);  (vi) the filing and recording fees and
expenses,  title  insurance  and  reasonable  fees and  expenses  of counsel for
providing to Lender all required  legal  opinions,  and other  similar  expenses


                                      -46-
<PAGE>
incurred in creating  and  perfecting  the Liens in favor of Lender  pursuant to
this Agreement and the other Loan  Documents;  (vii) enforcing or preserving any
rights, in response to third party claims or the prosecuting or defending of any
action  or  proceeding  or other  litigation,  in each  case  against,  under or
affecting Borrower, this Agreement,  the other Loan Documents,  the Property, or
any other security given for the Loan; and (viii)  enforcing any  obligations of
or collecting  any payments due from Borrower  under this  Agreement,  the other
Loan  Documents  or with  respect  to the  Property  or in  connection  with any
refinancing  or  restructuring  of the credit  arrangements  provided under this
Agreement  in the nature of a  "work-out"  or of any  insolvency  or  bankruptcy
proceedings;  provided,  however,  that  Borrower  shall not be  liable  for the
payment of any such costs and expenses to the extent the same arise by reason of
the gross negligence,  illegal acts, fraud or willful  misconduct of Lender. Any
costs and  expenses  due and payable to Lender  hereunder  which are not paid by
Borrower  within ten (10) days after  demand may be paid from any amounts in the
Cash Collateral Account, with notice thereof to Borrower.

     (b) Borrower shall  indemnify and hold harmless Lender from and against any
and all other liabilities,  obligations,  losses, damages,  penalties,  actions,
judgments,  suits,  claims,  costs,  expenses and  disbursements  of any kind or
nature  whatsoever  (including the reasonable fees and  disbursements of counsel
for Lender in  connection  with any  investigative,  administrative  or judicial
proceeding commenced or threatened,  whether or not Lender shall be designated a
party thereto),  that may be imposed on, incurred by, or asserted against Lender
in any manner  relating  to or arising  out of (i) any breach by Borrower of its
obligations  under, or any material  misrepresentation  by Borrower contained in
this Agreement or the other Loan Documents,  (ii) the use or intended use of the
proceeds of the Loan or (iii) any information provided by Borrower, or contained
in any  documentation  approved  by  Borrower  and in any  way  relating  to the
issuance,  offering and sale of the Securities  (collectively,  the "Indemnified
Liabilities"); provided, however, that Borrower shall not have any obligation to
Lender hereunder to the extent that such Indemnified  Liabilities arise from the
gross  negligence,  illegal acts, fraud or willful  misconduct of Lender. To the
extent that the  undertaking  to  indemnify  and hold  harmless set forth in the
preceding  sentence may be  unenforceable  because it violates any law or public
policy,  Borrower shall  contribute the maximum  portion that it is permitted to
pay and satisfy  under  applicable  law to the payment and  satisfaction  of all
Indemnified Liabilities incurred by Lender.

     Section 10.14 EXHIBITS INCORPORATED. The Exhibits annexed hereto are hereby
incorporated  herein as a part of this  Agreement with the same effect as if set
forth in the body hereof.

     Section 10.15 OFFSETS, COUNTERCLAIMS AND DEFENSES. Any assignee of Lender's
interest in and to this  Agreement,  the Note and the other Loan Documents shall
take the same free and clear of all offsets, counterclaims or defenses which are
unrelated  to such  documents  which  Borrower  may  otherwise  have against any
assignor of such documents,  and no such unrelated counterclaim or defense shall
be interposed or asserted by Borrower in any action or proceeding brought by any
such assignee upon such  documents and any such right to interpose or assert any
such unrelated offset,  counterclaim or defense in any such action or proceeding
is hereby expressly waived by Borrower.

     Section 10.16 NO JOINT VENTURE OR  PARTNERSHIP.  Borrower and Lender intend
that the  relationships  created hereunder and under the other Loan Documents be
solely that of borrower  and  lender.  Nothing  herein or therein is intended to
create  a  joint  venture,  partnership,  tenancy-in-common,  or  joint  tenancy
relationship between Borrower and Lender nor to grant Lender any interest in the
Property other than that of mortgagee or lender.

     Section 10.17  PUBLICITY.  All news  releases,  publicity or advertising by
Borrower or their  Affiliates  through  any media  intended to reach the general
public which refers to the Loan Documents or the financing evidenced by the Loan
Documents, to Lender, CCA Group, the Loan purchaser, the Servicer or the trustee
in a Securitization shall be subject to the prior written approval of Lender.

                  Section 10.18 WAIVER OF MARSHALLING OF ASSETS.  To the fullest
extent  Borrower may legally do so,  Borrower waives all rights to a marshalling
of the  assets  of  Borrower,  Borrower's  partners,  if any,  and  others  with
interests in Borrower,  and of  Borrower's  properties,  or to a sale in inverse
order of alienation in the event of foreclosure of the interests hereby created,
and agrees not to assert any right under any laws  pertaining to the marshalling
of assets,  the sale in inverse order of alienation,  homestead  exemption,  the
administration  of estates of  decedents,  or any other  matters  whatsoever  to
defeat,  reduce or affect the right of Lender under the Loan Documents to a sale
of the Property for the collection of the related indebtedness without any prior


                                      -47-
<PAGE>
or different resort for collection,  of the right of Lender or any deed of trust
trustee to the payment of the related  indebtedness  out of the net  proceeds of
the Property in preference to every other claimant whatsoever.

     Section 10.19 WAIVER OF  COUNTERCLAIM.  Borrower hereby waives the right to
assert a counterclaim,  other than a compulsory  counterclaim,  in any action or
proceeding brought against it by Lender or its agents, including Servicer.

     Section 10.20  CONFLICT;  CONSTRUCTION  OF  DOCUMENTS.  In the event of any
conflict  between the  provisions  of this  Agreement  and any of the other Loan
Documents,  the provisions of this Agreement  shall control.  The parties hereto
acknowledge  that  they were  represented  by  counsel  in  connection  with the
negotiation  and  drafting of the Loan  Documents  and that such Loan  Documents
shall not be subject to the  principle of construing  their meaning  against the
party which drafted same.

     Section 10.21 BROKERS AND FINANCIAL  ADVISORS.  Borrower hereby  represents
that it has dealt with no financial advisors, brokers,  underwriters,  placement
agents,  agents or finders in connection with the  transactions  contemplated by
this Agreement. Borrower and Lender hereby agree to indemnify and hold the other
harmless from and against any and all claims, liabilities, costs and expenses of
any kind in any way  relating to or arising from a claim by any Person that such
Person  acted  on  behalf  of the  indemnifying  party  in  connection  with the
transactions  contemplated  herein.  The  provisions of this Section 10.21 shall
survive the  expiration  and  termination of this Agreement and the repayment of
the Debt.

     Section 10.22 NO THIRD PARTY  BENEFICIARIES.  This  Agreement and the other
Loan  Documents  are solely for the benefit of Lender and  Borrower  and nothing
contained  in this  Agreement  or the other  Loan  Documents  shall be deemed to
confer upon anyone other than Lender and Borrower any right to insist upon or to
enforce the performance or observance of any of the obligations contained herein
or  therein.  All  conditions  to the  obligations  of  Lender  to make the Loan
hereunder are imposed  solely and  exclusively  for the benefit of Lender and no
other Person shall have standing to require  satisfaction  of such conditions in
accordance  with their terms or be entitled to assume that Lender will refuse to
make the Loan in the absence of strict compliance with any or all thereof and no
other Person shall under any circumstances be deemed to be a beneficiary of such
conditions,  any or all of which  may be  freely  waived  in whole or in part by
Lender if, in Lender's sole  discretion,  Lender deems it advisable or desirable
to do so.

     Section 10.23 PRIOR AGREEMENTS. This Agreement and the other Loan Documents
contain the entire agreement of the parties hereto and thereto in respect of the
transactions  contemplated hereby and thereby, and all prior agreements among or
between such parties,  whether oral or written,  are  superseded by the terms of
this Agreement and the other Loan Documents.

     Section 10.24 INTERPRETATION.  Notwithstanding  anything to the contrary in
this  Agreement  or the  other  Loan  Documents,  all  references  in this  Loan
Agreement  and the  other  Loan  Documents  to "the  continuance  of an Event of
Default  until  cured" or  analogous  language  shall  specifically  require the
acceptance  by Lender,  in its sole  discretion,  of such cure for such Event of
Default to be deemed cured.

     (i) Financial Information.  All financial data, including the statements of
cash flow and income and operating  expense,  that have been delivered to Lender
by Borrower in respect of the Property (i) are true, complete and correct in all
material  respects,  (ii)  accurately  represent the financial  condition of the
Property as of the date of such  reports and (iii) to the extent  prepared by an
independent  certified public  accounting firm, have been prepared in accordance
with  GAAP  consistently  applied  throughout  the  periods  covered,  except as
disclosed  therein.  Borrower has no  contingent  liabilities,  liabilities  for
taxes,  unusual  forward or long-term  commitments  or unrealized or anticipated
losses  from  any  unfavorable  commitments  that  are  known  to  Borrower  and
reasonably  likely to have a  materially  adverse  effect on the Property or the
operation  thereof,  except  as  referred  to or  reflected  in  said  financial
statements.  Since  the date of such  financial  statements,  there  has been no
materially adverse change in the financial condition,  operations or business of
Borrower from that set forth in said financial statements.

     (j) Federal Reserve  Regulations.  No part of the proceeds of the Loan will
be used for the purpose of purchasing or acquiring any "margin stock" within the
meaning of Regulation U of the Board of Governors of the Federal  Reserve System
or for any other purpose which would be  inconsistent  with such Regulation U or
any other Regulations of such Board of Governors, or for any purposes prohibited
by Legal  Requirements  or by the terms and  conditions of this Agreement or the
other Loan Documents.

     (k) Not a Foreign  Person.  Borrower is not a "foreign  person"  within the
meaning ofss.1445(f)(3) of the Code.

     (l)  Enforceability.  The Loan  Documents  are not  subject to any right of
rescission,  set-off, counterclaim or defense by Borrower, including the defense
of usury,  nor would the exercise of any of the terms of the Loan Documents,  or
the exercise of any right thereunder,  render the Loan Documents  unenforceable,
and Borrower has not asserted any right of rescission,  set-off, counterclaim or
defense with respect thereto.

     (m)  Single-Purpose.  Borrower  hereby  represents  and  warrants  to,  and
covenants  with,  Lender that,  as of the date hereof and until such time as the
Debt shall be paid in full:

          (i)  Borrower  does not and will not own any asset or  property  other
than (A) the Property Loan and (B) incidental  personal  property  necessary for
the ownership or operation of the Property Loan.

          (ii) Borrower will not engage in any business other than the ownership
of the Property Loan and will in all material  respects  conduct and operate its
business as presently conducted and operated.

          (iii)  Borrower will not enter into any contract or agreement with any
of its  Affiliates  or  constituent  parties,  Guarantor or any Affiliate of any
constituent  party or  Guarantor,  except  upon  terms and  conditions  that are
intrinsically fair and substantially similar to those that would be available on
an arms-length basis with third parties other than any such party.

          (iv)  Borrower  has not  incurred,  and Borrower  will not incur,  any
indebtedness,  secured or unsecured,  direct or indirect, absolute or contingent
(including guaranteeing any obligation),  other than the Permitted Indebtedness.
Except as set forth in the immediately preceding sentence, no indebtedness other
than the Debt may be secured (subordinate or pari passu) by the Property Loan.

          (v)  Borrower  has not made and will not make any loans or advances to
any third party (including any Affiliate or constituent party,  Guarantor or any
Affiliate of any constituent  party or Guarantor),  except for advances approved
by Lender to pay  redevelopment  costs in connection  with the Property that are
secured by the Property Loan Documents.

          (vi)  Borrower is and will  remain  solvent and will pay its debts and
liabilities  (including employment and overhead expenses) from its assets as the
same shall become due.

          (vii)  Borrower  has done or caused to be done and will do all  things
necessary  to  observe  corporate,  partnership,  or limited  liability  company
formalities, as the case may be, and preserve its existence.


                                      -15-
<PAGE>
          (viii) Borrower will not permit any constituent party or Guarantor to,
amend,  modify or  otherwise  change the  partnership  certificate,  partnership
agreement,  articles of incorporation and bylaws, trust,  operating agreement or
other  organizational  documents  of  Borrower  or  such  constituent  party  or
Guarantor in a manner which would  adversely  affect  Borrower's  existence as a
single purpose entity.

          (ix)  Borrower  will  maintain  books and  records  and bank  accounts
separate from those of its  Affiliates  and any  constituent  party and Borrower
will file its own tax returns.

          (x)  Borrower  will be, and at all times  will hold  itself out to the
public as, a legal entity separate and distinct from any other entity (including
any  Affiliate,  any  constituent  party,  Guarantor  or  any  Affiliate  of any
constituent  party or  Guarantor),  shall  conduct  business in its own name and
shall maintain and utilize separate stationery, invoices and checks.

          (xi)  Borrower  will   maintain   adequate   capital  for  the  normal
obligations  reasonably  foreseeable in a business of its size and character and
in light of its contemplated business operations.

          (xii)  Neither  Borrower  nor any  constituent  party  will  seek  the
dissolution or winding up, in whole or in part, of Borrower.

          (xiii)  Borrower  will not  commingle  its funds and other assets with
those of any Affiliate or constituent party,  Guarantor, or any Affiliate of any
constituent party or Guarantor, or any other person.

          (xiv)  Borrower has and will maintain its assets in such a manner that
it will not be costly or  difficult  to  segregate,  ascertain  or identify  its
individual assets from those of any Affiliate or constituent  party,  Guarantor,
or any Affiliate of any constituent party or Guarantor, or any other Person.

          (xv) Borrower does not and will not hold itself out to be  responsible
for the debts or obligations of any other Person.

          (xvi)  Borrower  shall at all times have one member (the "SPE Member")
who is a "single  purpose entity" and shall at all times comply with each of the
representations,  warranties,  and covenants contained in this Section 4.1 as if
such representation, warranty or covenant was made directly by such SPE Member.

          (xvii) The charter of the SPE Member shall at all times  have at least
one duly appointed member of its board of directors (an "Independent  Director")
reasonably  satisfactory  to Lender  who shall not have been at the time of such
individual's appointment, and may not have been at any time during the preceding
five (5) years (i) a member of, or an officer or employee of, Borrower or any of
its shareholders,  subsidiaries or Affiliates (except as an Independent Director
on any of their boards of directors),  (ii) a customer, or supplier, Borrower or
any of  its  members,  subsidiaries  or  Affiliates  (except  as an  Independent
Director on any of their  boards of  directors),  (iii) a person or other entity
controlling  any such  member,  supplier  or  customer  or (iv) a member  of the
immediate  family  of any  such  shareholder,  officer,  employee,  supplier  or
customer  of any other  director  of the SPE Member.  As used  herein,  the term
"control" means the possession,  directly or indirectly,  of the power to direct
or cause the  direction  of the  management  and policies of a person or entity,
whether through ownership of voting securities, by contract or otherwise.

          (xviii) The board of  directors  of the SPE Member  shall not take any
action which, under the terms of any certificate of incorporation, bylaws or any
voting trust  agreement  with respect to any common stock,  requires the vote of
the board of directors of the SPE Member unless at the time of such action there
shall be at least one member who is an Independent Director.

          (xix) Borrower shall conduct its business so that the assumptions made
with respect to Borrower in that certain  opinion letter dated as of the Closing
Date delivered by Borrower's  counsel in connection  with the Loan shall be true
and correct in all respects.

     (n) Investment Company Act. Borrower is not (i) an "investment  company" or
a company  "controlled"  by an "investment  company,"  within the meaning of the
Investment  Company  Act of 1940,  as  amended;  (ii) a "holding  company"  or a
"subsidiary  company"  of a  "holding  company"  or an  "affiliate"  of either a
"holding  company" or a  "subsidiary  company"  within the meaning of the Public
Utility Holding  Company Act of 1935, as amended;  or (iii) subject to any other
federal or state law or  regulation  which  purports to restrict or regulate its
ability to borrow money.


                                      -16-
<PAGE>
     (o) Fraudulent Transfer. Borrower has not entered into the Loan or any Loan
Document with the actual intent to hinder,  delay, or defraud any creditor,  and
Borrower  has  received   reasonably   equivalent  value  in  exchange  for  its
obligations  under  the  Loan  Documents.  Giving  effect  to  the  transactions
contemplated by the Loan Documents, the fair saleable value of Borrower's assets
exceeds and will,  immediately  following the execution and delivery of the Loan
Documents,   exceed  Borrower's  total  liabilities,   including   subordinated,
unliquidated,  disputed or contingent  liabilities.  The fair saleable  value of
Borrower's assets is and will,  immediately following the execution and delivery
of  the  Loan  Documents,  be  greater  than  Borrower's  probable  liabilities,
including the maximum amount of its contingent  liabilities or its debts as such
debts become  absolute and matured.  Borrower's  assets do not and,  immediately
following the execution and delivery of the Loan Documents will not,  constitute
unreasonably small capital to carry out its business as conducted or as proposed
to be conducted. Borrower does not intend to, and does not believe that it will,
incur  debts  and  liabilities   (including  contingent  liabilities  and  other
commitments)  beyond its ability to pay such debts as they mature  (taking  into
account the timing and amounts to be payable on or in respect of  obligations of
Borrower).

     Section 4.2 BORROWER REPRESENTATIONS  CONCERNING PROPERTY AND PROPERTY LOAN
DOCUMENTS.  Borrower represents and warrants as of the date hereof and as of the
Closing Date.

     (a) The Property Loan Documents are not subject to an assignment or pledge,

Property Loan Documents, free and clear of any loan participations,  third party
claims or other Liens.

     (b) The Borrower has full right and authority to sell,  assign and transfer
the Property  Loan and the  collateral  assignment  to the Lender  constitutes a
legal, valid and binding assignment of the Property Loan.

     (c) The Borrower is pledging  the  Property  Loan free and clear of any and
all liens, pledges,  charges or security interests of any nature encumbering the
Property Loan.

     (d) The Property Loan Documents are legal, valid and binding obligations of
the Owner,  enforceable  in accordance  with their terms,  and there is no valid
defense,  counterclaim,  right of  rescission  or right of set-off or  abatement
available to the Owner with respect to such Property Loan Documents.

     (e) The  Property  Loan  Documents  create  a  valid,  collateral  or first
priority  assignment of, or a valid first priority security interest in, certain
rights  under the  Leases,  subject  only to a license  granted  to the Owner to
exercise  certain rights and to perform certain  obligations of the lessor under
such leases,  including the right to operate the Property,  no Person other than
the Owner  owns any  interest  in any  payments  due under such  leases  that is
superior to or of equal priority with the Borrower's interest therein.

     (f) The Property Loan has not been waived,  modified,  altered,  satisfied,
canceled,  subordinated or rescinded and the Property has not been released from
the lien of the Property Loan  Documents in any manner except as provided in the

     (g) The Property Loan Documents  create a valid and enforceable  first lien
on the  Property,  and the  Property,  is free and clear of any  mechanic's  and
materialmen's  liens  which are prior to or equal with the lien of the  Property
Loan  Documents,  except  those  which are insured  against by a lender's  title
insurance policy (as described below).

     (h) The Borrower has not taken any action, nor has knowledge that the Owner
has taken any action,  that would cause the  representations and warranties made
by the Owner with respect to the Property Loan not to be true.

     (i) The Borrower has no knowledge  that the  representations  an warranties
made by the Owner with respect to the Property Loan are not true in any material
respect.

     (j) The lien created by the Property  Loan  Documents is insured by an ALTA

jurisdiction  issued  by one  or  more  nationally  recognized  title  insurance
companies,  insuring the Borrower as to a valid and first  priority  lien of the
Mortgage in at least the original principal amount of such Loan, subject only to
(a) the lien of current real property taxes, ground rents, water charges,  sewer
rents and  assessments  not yet due and payable,  (b) covenants,  conditions and


                                      -17-

restrictions,  rights of way,  easements  and other matters of public record set
forth in the Title  Policy,  none of which,  individually  or in the  aggregate,
materially  interferes  with the current use or operation of the Property or the
security intended to be provided by such Mortgage or with the Owner's ability to
pay its obligations  when they become due or the value,  use or operation of the
related  Mortgaged  Property and (c) the  exceptions  (general and specific) set
forth in such insurance policy, none of which, individually or in the aggregate,
materially interferes with the security intended to be provided by such Mortgage
or with the Owner's ability to pay its  obligations  when they become due or the
value, use or operation of the Property; the Borrower and Lender, its successors
or assigns are the sole named  insureds of such  policy as their  interests  may
appear; no claims have been made under such policy and the Borrower has not done
anything (by act or omission),  and the Borrower has no knowledge of any matter,
which would  impair or  diminish  the  coverage  of such policy in any  material
respect.

     (k) The  current  outstanding  principal  balance of the  Property  Loan is
$62,518,231.47. Borrower has no obligation to make any additional advances under
the Property Loan Documents.

     (l) No building or other  improvement  on the Property has been affected in
any material manner or suffered any material loss as a result of any fire, wind,
explosion,  accident or other cause and the  Property is free of any damage that

the Property Loan and is in good repair;  there is no proceeding pending for the
total or partial condemnation of the Property.

and authorizations are valid and in full force and effect.

     (n) (i) The  Property is insured by a fire and  extended  perils  insurance

an amount not less than the replacement  cost and the amount  necessary to avoid

          (ii) The Property is covered by business  interruption  insurance (for
at least 18  months  of rent  interruptions)  and the  Property  is  covered  by

          (iii)All premiums on any insurance  policies required to be paid as of
the Closing Date have been paid;

          (iv) The insurance  policies  require at least 30 days prior notice to
the  insured  of  termination  or  cancellation,  and no such  notice  has  been
received; and

          (v) The  Property  Loan  Documents  obligate the Owner to maintain all
such insurance and, at such Owner's failure to do so,  authorize the Borrower to
maintain   such   insurance  at  the  Owner's  cost  and  expense  and  to  seek
reimbursement therefor from such Owner.

     (o)  There is no  default,  breach,  violation  or  event  of  acceleration
existing under the Property Loan Documents and, to the Borrower's knowledge,  no
event that,  with the passage of time or with notice and the  expiration  of any
grace or cure period, would and does constitute a default,  breach, violation or
event of  acceleration  and the  Borrower  has not waived any  default,  breach,
violation or event of acceleration.

     (p) To the best of Borrower's  knowledge,  Owner is not a debtor in a state
or  federal  bankruptcy  or  insolvency  preceding.  To the  best of  Borrower's
knowledge,  the Property, is in material compliance with all applicable federal,
state and local  laws  pertaining  to  environmental  hazards,  and no notice of
violation of such laws has been issued by any governmental  agency or authority;
the Borrower has not taken any action that would cause the Property not to be in
material  compliance  with all  federal,  state and  local  laws  pertaining  to
environmental hazards.

     (q) To Borrower's knowledge the Property is in compliance,  in all material
respects,  with all applicable laws,  zoning  ordinances,  rules,  covenants and

certificates of occupancy (if applicable), whether by law, ordinance, regulation
or insurance  standards to be made or issued with respect to the Property,  have
been obtained and are in full force and effect.

limiting the right or ability of the Borrower to assign, transfer and convey the
Property Loan Documents to any other Person.

     (v) Attached  hereto as Schedule 2 is a rent roll (the "Rent Roll") for the
Property.  The Rent Roll is true,  correct and complete in all material respects
with  respect to the  subject  matter  thereof.  The only Leases  affecting  the
Property are those reflected in the Rent Roll. To Borrower's knowledge following
inquiry as a duly diligent  lender,  except as set forth in Schedule 1: (i) each
Lease is in full force and effect;  (ii) except for those Leases with terms that
have not yet commenced, the tenants under the Leases have accepted possession of

payment of rent under such Leases and there are no  offsets,  claims or defenses
to the  enforcement  thereof;  (iii) all rents due and payable  under the Leases
have been paid and no portion  thereof  has been paid for any  period  more than
thirty  (30) days in  advance;  (iv) the rent  payable  under  each Lease is the

constitute such default;  and (vi) there is no present  material  default by any
tenant  under any Lease.  None of the Leases  contains any option to purchase or
right of first refusal to purchase the Property or any part thereof.  The Leases
have not been assigned or pledged  except to Lender and  Borrower,  and no other
person  whatsoever  has any  interest  therein  except the tenants and  Landlord
thereunder pursuant to the Leases.

     (w) To Borrower's actual knowledge,  the survey for the Property  delivered
to Lender  in  connection  with  this  Agreement  does not fail to  reflect  any
material matter affecting the Property or the title thereto.

     Section 4.3 SURVIVAL OF  REPRESENTATIONS.  Borrower  agrees that all of the
representations  and  warranties  of  Borrower  set  forth  in  Section  4.1 and
elsewhere in this Agreement and in the other Loan Documents shall survive for so

other Loan Documents by Borrower. All representations, warranties, covenants and
agreements  made in this  Agreement  or in the other Loan  Documents by Borrower

investigation heretofore or hereafter made by Lender or on its behalf.

     (f) Cooperate in Legal  Proceedings.  Borrower shall  cooperate  fully with

     (j) Financial Reporting.

          (i)  Borrower  will cause Owner to keep and  maintain on a Fiscal Year
basis,  in accordance  with GAAP or another  method of  preparation  approved by

during  normal  business  hours upon  reasonable  notice to examine  such books,
records and accounts at the office of Borrower or other Person  maintaining such
books,  records and  accounts  and to make such  copies or  extracts  thereof as
Lender shall desire. After the occurrence and during the continuance of an Event
of  Default,  Borrower  shall pay any costs and  expenses  incurred by Lender to
examine  accounting  records  with  respect  to the  Property,  as Lender  shall
determine to be necessary or appropriate in the protection of Lender's interest.

          (ii)  Borrower  will  furnish  to Lender  promptly  upon  receipt  all
financial reports and other  information and documentation  provided to Borrower
under the Property Loan Documents.  Borrower shall also cause Manager to provide
such  information  regarding the Property as may be requested  from time to time
provided such information is customarily maintained by Borrower.

     (k)  Business  and  Operations.  Borrower  will  continue  to engage in the
business  presently  conducted by it.  Borrower  will qualify to do business and
will remain in good standing under the laws of each  jurisdiction  as and to the
extent the same are required for the conduct of its business.

     (l) Title to the Property  Loan.  Borrower  will warrant and defend (i) the
title to the Property Loan and (ii) the validity and priority of the Lien of the
Assignment  of Loan  Documents,  in each case  against the claims of all Persons
whomsoever.  Borrower shall reimburse Lender for any losses,  costs,  damages or
expenses  (including  reasonable  attorneys'  fees and court costs)  incurred by
Lender if an interest in the Property Loan,  other than as permitted  hereunder,
is claimed by another Person.

     (m) Costs of Enforcement.  In the event (i) that the Loan Documents are put
into the hands of an attorney for collection,  suit,  action or foreclosure,  or
(ii) of the bankruptcy,  insolvency,  rehabilitation or other similar proceeding
in respect of  Borrower or Owner or an  assignment  by Borrower or Owner for the
benefit  of its  creditors,  Borrower,  its  successors  or  assigns,  shall  be
chargeable with and agrees to pay all costs of collection and defense, including
reasonable  attorneys'  fees in connection  therewith and in connection with any
appellate  proceeding or post-judgment  action involved therein,  which shall be
due and payable together with all required service or use taxes.

     (n) Estoppel Statement.

          (i) After  request  by  Lender,  Borrower  shall  within ten (10) days
furnish Lender with a statement, duly acknowledged and certified,  setting forth
(A) the  unpaid  principal  amount of the Note and the  Property  Loan,  (B) the
Interest  Rate of the  Note,  (C)  the  date  installments  of  interest  and/or
principal  were last paid on the Note and  Property  Loan,  (D) any  offsets  or
defenses  to the  payment  of the  Debt,  if any and (E)  that  the  Note,  this
Agreement,  the  Mortgage  and the other Loan  Documents  are  valid,  legal and
binding  obligations  and  have  not  been  modified  or  if  modified,   giving
particulars of such modification.

          (ii) After request by Lender (but no more  frequently than once in any
year),  Borrower  shall within ten (10) days furnish  Lender with a  certificate
reaffirming all  representations and warranties of Borrower set forth herein and
in the other Loan Documents as of the date requested by Lender or, to the extent
of any  changes to any such  representations  and  warranties,  so stating  such
changes.

     (o) Loan Proceeds.  Borrower shall use the proceeds of the Loan received by
it on the Closing Date only for the purposes set forth in Section 2.1.4.

     (p)  Amendments  by  Borrower.  Borrower  shall not enter into or otherwise
suffer  or  permit  any  amendment,  waiver,  supplement,  termination  or other
modification of any Loan Document executed and delivered by Borrower without the
prior written consent of Lender.



                                      -21-
<PAGE>
     (q) Confirmation of  Representations.  In addition to and not in limitation
of the covenants and agreements of Borrower  contained in Section 9.1,  Borrower
shall  deliver,  in  connection  with  any  Secondary  Market  Transaction,  (i)
Officer's Certificates certifying as to the accuracy of all representations made
by  Borrower  in the  Loan  Documents  as of the  date  of the  closing  of such
Secondary  Market  Transaction  (with  such  modification  thereto  to make such
representation  factually  accurate)  and  (ii)  certificates  of  the  relevant
Governmental  Authorities  in all  relevant  jurisdictions  indicating  the good
standing and  qualification  of Borrower as of the date of the Secondary  Market
Transaction.

     (r) Budgets.  Borrower  shall  furnish to Lender  promptly upon receipt all
budgets and other  information  received by Borrower under the terms of the Cash
Collateral Account Agreement or Management Agreement. Borrower shall not approve
any budget or consent to any  disbursement  requiring  its approval  without the
prior consent of Lender.

     (s) No Joint Assessment.  Borrower shall not suffer, permit or initiate the
joint assessment of the Property (i) with any other real property constituting a
tax lot  separate  from the  Property  and (ii) with any portion of the Property
which may be deemed to  constitute  personal  property,  or any other  procedure
whereby the lien of any taxes which may be levied against such personal property
shall be assessed or levied or charged to the Property.

     (t) Principal  Place of Business.  Borrower  shall not change its principal
place of business set forth on the first page of this  Agreement  without  first
giving Lender thirty (30) days prior written notice.

     (u)  Interest  Rate  Protection.  Attached  hereto as Exhibit D is Lender's
standard form of forward rate lock  agreement (the "Rate Lock  Agreement").  The
defined terms used in this Section 5.1(x) and not otherwise defined herein shall
have the  meanings set forth in the Rate Lock  Agreement.  If at any time during
the term of the Loan the  hypothetical  loan  constant  determined  by using the
Benchmark  Treasury  Rate,  a loan spread of 200 basis  points,  and  assuming a
thirty year  amortization  schedule  would exceed  9.23%,  then Borrower will be
required  to  immediately  lock an  interest  rate  pursuant  to the  Rate  Lock
Agreement for an Anticipated Loan Amount equal to the outstanding balance of the
Loan, for an effective term of ten years, and for a Rate Lock Period expiring no
earlier  than the Stated  Maturity  Date.  The  "number of months  forward"  for
purposes of the Rate Lock Agreement  shall be the number of months from the time
of the rate lock to the Stated Maturity Date. Borrowers agree to enter execute a
Rate Lock  Agreement  reflecting  the terms of the rate  lock upon  notice  from
Lender but all  references  to a Rate Lock  Deposit  shall be deleted.  Borrower
hereby irrevocably  designates Capital America as its  attorney-in-fact  to lock
its interest rate in accordance  with the foregoing and do all things  necessary
and required in order to effectuate  and  consummate the rate lock and such rate
lock shall be  governed  by the terms of the Rate Lock  Agreement  with the same
effect as if Borrower  and Capital  America had  actually  executed it. Any such
agreement shall be considered a Loan Document  hereunder and shall be secured by
all the Loan  Documents  and  covered  by the  terms of the  Guaranty.  Borrower
acknowledges and agrees that although Lender has the right to unilaterally  lock
the rate at any time the  hypothetical  debt  service  constant  exceeds  9.23%,
Lender  shall have no  liability to Borrower if it does not lock such rate or if
it does not lock the rate at the  lowest  possible  rate  provided  that  Lender
agrees  to act in good  faith to lock the rate at a market  rate at the time the
rate lock occurs. Borrower further acknowledges that the rate locked will affect
the pricing on any  permanent  financing  that may be  available  from Lender in
order to repay this  Facility.  If Borrower  obtains  permanent  financing  from
Lender the hedge  position  pursuant to the Rate Lock  Agreement  can be used in
connection with such permanent  financing.  If Borrower repays the Loan and does
not obtain permanent financing from Lender, then Borrower  acknowledges that the
corresponding  hedge  positions in connection  with the Rate Lock Agreement will
need to be unwound and that any losses incurred shall be the  responsibility  of
Borrower.  If any gains are realized in  connection  with the  unwinding of such
hedge  position,  then such  gains  will be  applied  by  Lender  to reduce  the
outstanding balance of the Loan.

     Section 5.2 SPECIAL COVENANTS REGARDING THE PROPERTY LOAN.

     (a) Notice of  Defaults.  Promptly  upon  becoming  aware of the same,  the
Borrower  shall notify the Lender of any default or event of default  (howsoever
denominated)  under any  Property  Loan  Document  which  continues  beyond  any
applicable  notice or grace  period.  The Borrower  shall deliver to the Lender,
promptly  after  receipt  thereof,  copies  of all  material  notices  and other
material correspondence from Owner.



                                      -22-
<PAGE>
     (b)  Enforcement.  Subject  to the Loan  Documents,  Borrower  shall,  with
Lender's  prior written  consent  (which shall not be  unreasonably  withheld or
delayed),  enforce all of the material  terms,  conditions and provisions of the
Property  Loan  Documents;   provided,  however,  Borrower  will  not  take  any
enforcement  or other  action that could  adversely  affect the  priority of the
Property Loan  Documents.  If an event of default  (however  denominated)  shall
occur under the Property Loan, Borrower shall, at Lender's direction,  take such
lawful  and  appropriate   enforcement  or  other  remedial  actions  as  deemed
reasonably necessary by Lender subject to the Loan Documents. If Lender consents
to Borrower  foreclosing the Mortgage or acquiring the Property by conveyance in
lieu of foreclosure,  then Borrower shall take all steps reasonably necessary so
that upon such foreclosure, Lender shall simultaneously receive a first mortgage
on the  Property  to  secure  the  Loan and such  related  collateral  as may be
customary for Lender to receive in connection with similar first mortgage loans.

     (c)  Subordinate  Loan.  Borrower shall not consent to any  modification or
amendment  of, or waive any of the terms and  conditions  of, the  Subordination
Agreement or any of the documents  evidencing or securing the Subordinate  Loan,
Borrower  shall not consent to the  granting of any  additional  security or any
guaranty for all or any part of the Subordinate Loan.

     (d)  Application  of Funds.  Any funds received or collected by Borrower in
respect of the  Property  Loan in any  manner  whatsoever,  whether by  payment,
prepayment,  foreclosure or otherwise, shall be received and held by Borrower in
accordance  with and subject to the  provisions of this  Agreement and the other
Loan  Documents  and the same shall be paid to such escrow or other  accounts or
over to Lender as required under this Agreement and the other Loan Documents. If
Borrower  receives any  prepayment of principal,  Borrower  shall be required to
prepay a like amount of the outstanding  balance of the Loan. Borrower shall not
modify or attempt to modify the instructions to the Cash Collateral Account Bank
and any such  attempted  modification  shall be  deemed  null and void and of no
force and effect.

     (e) Notice of Casualty or  Condemnation.  Borrower  shall  promptly  notify
Lender of any casualty or the commencement of any condemnation proceedings which
affect any portion of the Property.

     (f) Release or  Amendment.  The Borrower  shall not release any  collateral
securing,  or any Person  liable for, the payment or  performance  of all or any
part of the Property Loan or amend or modify any of the Property Loan  Documents
without the prior  written  consent of Lender.  Without  limiting the  foregoing
Borrower  shall not accept a conveyance  of the Property in lieu of  foreclosure
with Lender's prior written consent.

     (g)  Performance.  Borrower  shall perform all of its material  obligations
under the Property Loan Documents.

     (h)  Management  Agreement.  The Borrower  shall not consent to any waiver,
termination,  amendment or cancellation of any management agreement, without the
Lender's prior written consent.

     (i) Leases. If, under the terms of any of the Property Documents,  Owner is
obligated  to obtain  Borrower's  consent  to any new  Lease or other  occupancy
arrangement  relating to the Property,  or any  amendment to an existing  Lease,
then, prior to granting such consent,  Borrower shall be obligated to provide to
Lender any information provided to Borrower by Owner regarding such Lease and to
obtain Lender's prior written approval of Borrower  granting such consent (which
approval  shall not be  unreasonably  withheld or  delayed)  and shall be deemed
given unless Lender  affirmatively  denies such request within ten (10) Business
Days.

     (j) Consents and Waivers.  Borrower shall not grant any consents or waivers
under the terms of the Property Loan Documents without the prior written consent
of Lender.

VI.  NEGATIVE COVENANTS
     ------------------

     Section 6.1  Borrower's  Negative  Covenants.  From the date  hereof  until
payment and  performance  in full of all  obligations of Borrower under the Loan
Documents,  Borrower  covenants  and  agrees  with  Lender  that it will not do,
directly or indirectly, any of the following:

          (a) Dissolution.  Borrower shall not dissolve,  terminate,  liquidate,
merge with or consolidate into another Person.



                                      -23-
<PAGE>
          (b)  Change In  Business.  Borrower  shall not enter  into any line of
 business other than the ownership and operation of the Property Loan.

          (c) Debt Cancellation.  Borrower shall not cancel or otherwise forgive
or release any claim or debt owed to Borrower by any Person, except for adequate
consideration  and  in  the  ordinary  course  of  Borrower's  business  in  its
reasonable judgment.

          (d)  Affiliate  Transactions.  Borrower  shall not enter into, or be a
party to, any transaction with an Affiliate of Borrower or any of the members of
Borrower  except in the ordinary course of business and on terms which are fully
disclosed  to Lender in advance  and are no less  favorable  to Borrower or such
Affiliate than would be obtained in a comparable arms-length transaction with an
unrelated third party.

          (e)  Zoning.  Borrower  shall not  initiate  or  consent to any zoning
reclassification  of any  portion of any of the  Property  or seek any  variance
under any existing  zoning  ordinance or permit the use of any portion of any of
the   Property  in  any  manner  that  could  result  in  such  use  becoming  a
non-conforming  use under any zoning  ordinance or any other applicable land use
law, rule or regulation, without the prior consent of Lender.

          (f)  Debt.  Borrower  shall  not  create,  incur  or  assume  any debt
(including  subordinate debt) other than the Debt. In addition, no Person owning
any interest in Borrower  shall  pledge,  transfer or  otherwise  dispose of its
interest  in Borrower to secure any  financing  for the benefit of such  Person,
Borrower or the Property.

          (g) Transfers.  Borrower shall not,  without the prior written consent
of Lender,  suffer or permit the sale,  assignment  or  transfer  (collectively,
"Transfer")  of (i) all or any  part  of the  Property  Loan,  (ii)  any  direct
interest in  Borrower or (iii) any direct or indirect  interest in any member of
Borrower  other than (A) the  issuance or transfer of  beneficial  interests  in
Prime Group Realty Trust, a Maryland real estate  investment  trust,  so long as
such  issuance or transfer does not result in a change in Control of Prime Group
Realty  Trust and so long as such  issuance  or  transfer  does not  affect  the
non-consolidation  opinion  delivered  by  Borrower,  and  (B) the  issuance  or
transfer of limited  partner  interests  in Prime Group  Realty L.P., a Delaware
limited  partnership,  or a  conversion  of a one  percent  general  partnership
interest owned  beneficially  by The Nardi Group,  L.L.C.  in Prime Group Realty
L.P. into a limited partnership  interest in Prime Group Realty L.P., so long as
such  issuance or transfer does not result in a change in Control of Prime Group
Realty  L.P.  and so long as such  issuance  or  transfer  does not  affect  the
non-consolidation  opinion  delivered by Borrower.  No Transfer  consented to by
Lender  pursuant to clause (ii) or (iii) above shall be permitted  unless Lender
shall have received (a) evidence in writing from the applicable  Rating Agencies
to  the  effect  that  such a  Transfer  will  not  result  in a  qualification,
withdrawal or  downgrading  of the ratings in effect  immediately  prior to such
Transfer for the Securities issued in connection with the  Securitization  which
are then outstanding and (b) a non-consolidation  opinion satisfactory to Lender
from the transferee's counsel. On or before the completion of any such permitted
Transfer,  Borrower  will pay all  reasonable  expenses  of Lender  incurred  in
connection therewith. Notwithstanding anything to the contrary contained in this
clause (j),  holders of  interests  in Borrower  (or holders of interests in any
entity  directly or  indirectly  holding an interest in Borrower) as of the date
hereof (the "Interest  Holders") shall have the right to transfer their interest
in  Borrower  (or any entity  directly  or  indirectly  holding an  interest  in
Borrower) to another  Person who is not an Interest  Holder,  including  without
limitation  immediate  family  members  for estate  planning  purposes,  without
Lender's consent; provided, however, that:

               (i) after  taking into  account any prior  transfers  pursuant to
this sentence, whether to the proposed transferee or otherwise, no such transfer
(or series of transfers) shall result in (A) the proposed  transferee,  together
with all members of his/her immediate family or any affiliates  thereof,  owning
in the aggregate  (directly,  indirectly or  beneficially)  more than 20% of the
interests in Borrower (or any entity directly or indirectly  holding an interest
in  Borrower)  or (B) a  transfer  in the  aggregate  of  more  than  20% of the
interests in Borrower as of the date hereof;

               (ii) no such  transfer  of interest  shall  result in a change of
control of Borrower;

               (iii) Borrower shall give Lender notice of such transfer together
with copies of all  instruments  effecting  such transfer not less than ten (10)
days prior to the date of such transfer;

               (iv) no Event of Default has occurred and remains uncured; and
                                      -24-
<PAGE>
               (v) the legal and  financial  structure  of  Borrower  after such
transfer and its members and the single purpose nature and bankruptcy remoteness
of Borrower and its shareholders,  partners or members  satisfies  Lender's then
current  applicable  underwriting  criteria and requirements,  including without
limitation  the  requirement  at  the  request  of  Lender  to  deliver  written
confirmations from the Rating Agencies that such transfer or series of transfers
will  not  result  in a  qualification,  downgrade  or  withdrawal  of the  then
applicable ratings.

For  purposes of this clause (j),  (A) a change of control of Borrower  shall be
deemed to have occurred if there is any change in the identity of the individual
or entities or group of individuals or entities who have the right, by virtue of
any  partnership  agreement,  articles  of  incorporation,  bylaws,  articles of
organization, operating agreement or any other agreement, with or without taking
any  formative  action,  to cause  Borrower  to take some  action or to prevent,
restrict or impede  Borrower  from taking some  action  which,  in either  case,
Borrower  could take or could  refrain from taking were it not for the rights of
such individuals;  and (B) an "immediate family member" shall mean a spouse or a
child of any Interest Holder.

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

     Section 7.1 INSURANCE; CASUALTY AND CONDEMNATION.

     7.1.1 INSURANCE.

     (a) Borrower,  at no cost to Lender, for the mutual benefit of Borrower and
Lender,  shall cause Owner to keep the Property  insured and obtain and maintain
during  the Term  policies  of  insurance  insuring  against  loss or  damage by
standard, "all-risk" perils in accordance with the Property Loan Documents. Such
insurance  (i) shall be in an amount  equal to the greatest of (A) the then full
replacement  cost of the Property without  deduction for physical  depreciation,
(B) the outstanding  principal  balance of the Loan and (C) such amount that the
insurer  would not deem  Borrower a co-insurer  under said policies and (ii) and
shall have deductibles no greater than five percent (5%) of the full replacement
cost of the  Property.  The premiums for such  policies of insurance  carried in
accordance  with this  paragraph  shall be paid  annually  in advance  and shall
contain a "Replacement Cost Endorsement" with a waiver of depreciation.

     (b) Borrower,  at no cost to Lender, for the mutual benefit of Borrower and
Lender,  shall  also  cause  Owner to obtain  and  maintain  during the Term the
following policies of insurance:

          (i) Flood  insurance if any part of the Property is located in an area
identified by the Federal Emergency  Management Agency as an area having special
flood  hazards and in which flood  insurance has been made  available  under the
National Flood Insurance  Program in an amount at least equal to the Debt or the
maximum  limit of coverage  available  with respect to the  Property  under said
program, whichever is less.

          (ii)  Commercial  general  liability  insurance,  including broad form
property  damage,  blanket  contractual and personal  injuries  (including death
resulting  therefrom)  coverages and containing minimum limits per occurrence of
$1,000,000 and $2,000,000 in the aggregate for any policy year. In addition,  at
least $10,000,000 excess and/or umbrella  liability  insurance shall be obtained

upon  Borrower and all court costs and  attorneys'  fees  incurred in connection
with the ownership, operation and maintenance of the Property.

          (iii) Rental loss and/or business interruption  insurance in an amount
equal to the greater of (A) the estimated  gross revenues from the operations of
the  Property  for the next  succeeding  eighteen  (18) month  period or (B) the
projected  operating  expenses  (including Debt Service) for the maintenance and
operation of the Property for the next  succeeding  eighteen  (18) month period.
The amount of such  insurance  shall be  increased  from time to time during the
Term as and when the Rents  increase or the  estimate  of (or the actual)  gross
revenue, as may be applicable, increases.

          (iv)  Insurance  against  loss or damage from (A) leakage of sprinkler
systems and (B) explosion of steam boilers,  air  conditioning  equipment,  high
pressure piping, machinery and equipment,  pressure vessels or similar apparatus

explosions), in an amount at least equal to $2,000,000 for the Property.

          (v) Worker's  compensation  insurance with respect to any employees of
Borrower, as required by any governmental authority or legal requirement.

                                      -25-
<PAGE>
          (vi) During any period of repair or restoration,  builder's "all risk"
insurance  in an amount equal to not less than the full  insurable  value of the
Property against such risks  (including fire and extended  coverage and collapse
of the  Improvements  to agreed  limits)  as  Lender  may  request,  in form and
substance acceptable to Lender.

          (vii)  Coverage  to  compensate  for the  cost of  demolition  and the
increased cost of  construction  for the Property in an amount  satisfactory  to
Lender.

          (viii)  Such other  insurance  as may from time to time be  reasonably
required by Lender in order to protect its interests.

     (c) All policies of insurance (the "Policies") required pursuant to Section
7.1.1(b) shall be issued by companies reasonably approved by Lender and licensed
to do  business  in the State,  with a claims  paying  ability  rating of "A" or
better by Standard & Poor's  Ratings  Group;  (ii) shall name  Borrower  and its
successors  and/or assigns as their interest may appear as the mortgagee;  (iii)
shall  contain a  Non-Contributory  Standard  Lender  Clause and a Lender's Loss
Payable  Endorsement,  or their  equivalents,  naming  Borrower as the person to
which all payments  made by such  insurance  company  shall be paid;  (iv) shall
contain  a waiver  of  subrogation  against  Lender;  (v)  shall  be  maintained
throughout  the Term  without  cost to Lender;  (vi) shall be  assigned  and the
certificates  thereof delivered to Lender; and (vii) shall contain  endorsements
providing  that  neither  Borrower,  Lender  nor  any  other  party  shall  be a
co-insurer  under said  Policies and that Lender  shall  receive at least thirty
(30) days prior written notice of any modification, reduction or cancellation of
any of the Policies;  and (viii) shall be  satisfactory in form and substance to
Lender and shall be  approved  by Lender as to  amounts,  form,  risk  coverage,
deductibles,  loss payees and insureds.  Borrower shall require Owner to pay the
premiums for such Policies (the "Insurance Premiums") as the same become due and
payable  and shall  furnish  to Lender  evidence  of the  renewal of each of the
Policies  with  receipts  for the  payment of the  Insurance  Premiums  or other
evidence of such payment reasonably satisfactory to Lender. If Borrower does not
furnish  such  evidence  and  receipts  at  least  ten  (10)  days  prior to the
expiration  of any expiring  Policy,  then Lender may procure,  but shall not be
obligated to procure,  such insurance and pay the Insurance  Premiums  therefor,
and Borrower agrees to reimburse Lender for the cost of such Insurance  Premiums
promptly on demand.  Within thirty (30) days after  request by Lender,  Borrower
shall  require Owner to obtain,  provided  Borrower has the right to do so under
the Property Loan Documents,  such increases in the amounts of coverage required
hereunder as may be reasonably  requested by Lender,  taking into  consideration
changes in the value of money over time,  changes in liability laws, and changes
in prudent customs and practices.

     (d) If any Property is damaged or  destroyed,  in whole or in part, by fire
or other  casualty (an "Insured  Casualty"),  Borrower  shall give prompt notice
thereof to Lender.  Following the occurrence of an Insured Casualty,  unless the
Loan is repaid in full,  Borrower  shall  cause  Owner to  promptly  proceed  to
restore,  repair,  replace or rebuild the Property to be of at least equal value
and of substantially  the same character as prior to such damage or destruction,
all to be effected in accordance with Legal Requirements.  The expenses incurred
by Lender in the adjustment  and  collection of insurance  proceeds shall become
part of the Debt and be secured  hereby and shall be  reimbursed  by Borrower to
Lender upon demand.

     7.1.2 CASUALTY AND APPLICATION OF PROCEEDS.

     (a) In  case  of  loss  or  damages  covered  by any of the  Policies,  the
following provisions shall apply subject to the terms, provisions and conditions
of the Property Loan Documents:

          (i) If an Insured  Casualty  does not exceed  $200,000,  Borrower  may
settle and adjust (or allow Owner to settle and  adjust)  any claim  without the
consent of Lender;  provided that such  adjustment is carried out in a competent
and timely manner.  In such case,  Borrower is hereby  authorized to collect and
receipt for any such insurance proceeds.

          (ii) If an Insured Casualty shall equal or exceed  $200,000,  Borrower
may settle and adjust (or allow  Owner to settle and  adjust) any claim but only
with the consent of Lender and agree with the insurance  company or companies on
the amount to be paid on the loss,  and the proceeds of any such policy shall be
due and payable  solely to Borrower,  as mortgagee,  but in accordance  with the
terms  hereof  held in escrow  by  Lender  (to the  extent  permitted  under the
Property Loan Documents) and otherwise  pursuant to the Cash Collateral  Account
Agreement and Custody Agreement.


                                      -26-
<PAGE>
     (b) In the event of an Insured  Casualty  where the loss is in an aggregate
amount less than $2,000,000,  and if, in the reasonable  judgment of Lender, the
Property  can be  restored  within six (6) months to an  economic  unit not less
valuable  and not less useful  than the same was prior to the Insured  Casualty,
and after such restoration will adequately  secure the Debt, then, if no Default
or Event of Default shall have occurred and be then continuing,  the proceeds of
insurance  (after  reimbursement  of any expenses  incurred by Lender)  shall be
applied to reimburse  Owner for the cost of restoring,  repairing,  replacing or
rebuilding  the Property or part thereof  subject to the Insured  Casualty  (the
"Restoration"),  in the manner set forth herein.  Borrower hereby  covenants and
agrees to cause Owner to commence and  diligently  prosecute  such  Restoration;
provided  that (i)  Borrower  shall pay all costs  (and if  required  by Lender,
Borrower  shall  deposit  the total  thereof  with  Lender in  advance)  of such
Restoration in excess of the net proceeds of insurance  made available  pursuant
to the terms hereof;  (ii) the Restoration  shall be done in compliance with all
Legal  Requirements;  and (iii) Lender shall have received  evidence  reasonably
satisfactory to it that,  during the period of the  Restoration,  the sum of (A)
income derived from the Property,  as reasonably  determined by Lender, plus (B)
proceeds of rent loss insurance or business interruption  insurance,  if any, to
be paid will  equal or exceed the sum of (I)  expenses  in  connection  with the
operation of the Property and (II) the Debt Service under the Loan.

     (c) Except as provided above, the proceeds of insurance  collected upon any
Insured  Casualty  shall,  at the  option of Lender in its sole  discretion,  be
applied to the  payment of the Debt or applied to allow  Borrower  to  reimburse
Owner for the cost of any  Restoration,  in the manner set forth below.  If such
proceeds are applied to the Debit, no fee pursuant to Section 2.3.1 shall be due
in connection with such payment.

     (d) If Borrower is entitled to reimbursement out of insurance proceeds held
by Lender,  such proceeds shall be disbursed from time to time upon Lender being
furnished  with  (i)  evidence  satisfactory  to it of  the  estimated  cost  of
completion of the  Restoration,  (ii) funds or, at Lender's  option,  assurances
satisfactory to Lender that such funds are available,  sufficient in addition to
the  proceeds of insurance  to complete  the  proposed  Restoration,  (iii) such
architect's certificates,  waivers of lien, contractor's sworn statements, title
insurance endorsements, bonds, plats of survey and such other evidences of cost,
payment and  performance as Lender may  reasonably  require and approve and (iv)
all plans and specifications for such Restoration, such plans and specifications
to be approved by Lender prior to  commencement  of any work.  In  addition,  no
payment  made prior to the final  completion  of the  Restoration  shall  exceed
ninety percent (90%) of the value of the work performed from time to time; funds
other than proceeds of insurance  shall be disbursed  prior to  disbursement  of
such  proceeds;  and at all times,  the  undisbursed  balance  of such  proceeds
remaining in the hands of Lender, together with funds deposited for that purpose
or  irrevocably  committed  to the  satisfaction  of  Lender  by or on behalf of
Borrower  for  that  purpose,  shall be at least  sufficient  in the  reasonable
judgment of Lender to pay for the cost of  completion of the  Restoration,  free
and clear of all liens or claims for lien.  Any surplus  which may remain out of
insurance  proceeds  held by Lender after  payment of such costs of  Restoration
shall be paid to Borrower.

     7.1.3 CONDEMNATION.

     (a) Borrower  shall  promptly give Lender  written  notice of the actual or
threatened  commencement  of  any  condemnation  or  eminent  domain  proceeding
affecting the Property (a "Condemnation")  and shall deliver to Lender copies of
any and all papers served in connection  with such  Condemnation.  Following the
occurrence  of a  Condemnation,  Borrower,  regardless  of  whether  an Award is
available,  shall promptly cause Owner to proceed to restore, repair, replace or
rebuild the Property to the extent practicable to be of at least equal value and
of  substantially  the same character as prior to such  Condemnation,  all to be
effected in accordance with Legal Requirements.

     (b) Lender is hereby irrevocably appointed as Borrower's  attorney-in-fact,
coupled with an interest,  with  exclusive  power to exercise all of  Borrower's
rights to  collect,  receive  and  retain  any award or  payment in respect of a
Condemnation (an "Award") and to make any compromise or settlement in connection
with such  Condemnation,  subject  to the  provisions  of this  Section  and the
Property  Loan  Documents.  Notwithstanding  any  Condemnation  by any public or
quasi-public   authority   (including  any  transfer  made  in  lieu  of  or  in
anticipation of such a Condemnation), Borrower shall continue to pay the Debt at
the time and in the manner  provided for in the Note, in this  Agreement and the
other Loan  Documents  and the Debt  shall not be  reduced  unless and until any
Award  shall have been  actually  received  and applied by Lender to expenses of
collecting  the Award and to discharge of the Debt.  Lender shall not be limited


                                      -27-
<PAGE>
to the  interest  paid on the  Award by the  condemning  authority  but shall be
entitled to receive out of the Award  interest at the rate or rates  provided in
the Note.  Borrower shall cause any Award that is payable to Borrower to be paid
directly to Lender.

     (c) In the event of any  Condemnation  where  the Award is in an  aggregate
amount less than $2,000,000,  and if, in the reasonable  judgment of Lender, the
Property  can be  restored  within six (6) months to an  economic  unit not less
valuable  and not less useful than the same was prior to the  Condemnation,  and
after such restoration  will adequately  secure the Debt, then, if no Default or
Event of Default shall have occurred and be then continuing, the proceeds of the
Award (after  reimbursement of any expenses incurred by Lender) shall be applied
to reimburse Owner for the cost of restoring, repairing, replacing or rebuilding
the  Property  or  part  thereof  subject  to  Condemnation  (the  "Condemnation
Restoration")  in the manner  set forth  below.  Subject to the Loan  Documents,
Borrower  hereby  covenants and agrees to cause Owner to commence and diligently
to prosecute  such  Condemnation  Restoration;  provided that (i) Borrower shall
cause Owner to pay all costs (and if required by Lender,  Borrower shall deposit
the total thereof with Lender in advance) of such  Condemnation  Restoration  in
excess of the Award  made  available  pursuant  to the  terms  hereof;  (ii) the
Condemnation   Restoration   shall  be  done  in   compliance   with  all  Legal
Requirements;   and  (iii)  Lender  shall  have  received  evidence   reasonably
satisfactory to it that, during the period of the Condemnation Restoration,  the
sum of (A) income derived from the Property, as reasonably determined by Lender,
plus (B) proceeds of rent loss insurance or business interruption  insurance, if
any, to be paid will equal or exceed the sum of (I) expenses in connection  with
the operation of the Property and (II) the Debt Service under the Loan.

     (d) Except as provided  above,  the Award  collected upon any  Condemnation
shall, at the option of Lender in its sole discretion, be applied to the payment
of the Debt or applied to allow Borrower to reimburse  Owner for the cost of the
Condemnation  Restoration in the manner set forth below. If the Award is applied
to the Debt, no fee pursuant to Section  2.3.1 shall be due in  connection  with
such payment.

     (e) In the event  Borrower is entitled  to  reimbursement  out of the Award
received by Lender,  such  proceeds  shall be  disbursed  from time to time upon
Lender being  furnished  with (i) evidence  satisfactory  to it of the estimated
cost of completion of the Condemnation  Restoration,  (ii) funds or, at Lender's
option,  assurances  satisfactory  to  Lender  that such  funds  are  available,
sufficient in addition to the proceeds of the Award to complete the Condemnation
Restoration, (iii) such architect's certificates,  waivers of lien, contractor's
sworn statements, title insurance endorsements,  bonds, plats of survey and such
other  evidences  of costs,  payment and  performance  as Lender may  reasonably
require and approve; and (iv) all plans and specifications for such Condemnation
Restoration,  such plans and  specifications  to be approved by Lender  prior to
commencement of work. In addition, no payment made prior to the final completion
of the  restoration,  repair,  replacement  and  rebuilding  shall exceed ninety
percent (90%) of the value of the work  performed  from time to time;  (y) funds
other than  proceeds of the Award shall be disbursed  prior to  disbursement  of
such proceeds;  and (z) at all times,  the undisbursed  balance of such proceeds
remaining in the hands of Lender, together with funds deposited for that purpose
or  irrevocably  committed  to the  satisfaction  of  Lender  by or on behalf of
Borrower  for  that  purpose,  shall be at least  sufficient  in the  reasonable
judgment  of  Lender  to pay for the  costs of  completion  of the  Condemnation
Restoration  free and clear of all liens or claims for lien.  Any surplus  which
may remain out of the Award  received by Lender  after  payment of such costs of
restoration,  repair,  replacement or rebuilding shall, in the sole and absolute
discretion of Lender, be retained by Lender and applied to payment of the Debt.

covenants of the Loan Documents and this Agreement on Borrower's part to be paid
and  performed,  all of  Borrower's  right,  title  and  interest  in and to the
Required  Repair  Fund and the  Required  Repair  Account.  Borrower  shall not,
without obtaining the prior written consent of Lender, further pledge, assign or
grant any security  interest in the Required  Repair Fund or the Required Repair
Account or permit any lien or encumbrance to attach  thereto,  or any levy to be
made thereon, or any UCC-l Financing  Statements,  except those naming Lender as

date on which  Borrower  requests such payment be made (except in the case of an
emergency repair which requires immediate attention, in which event Borrower may
submit such payment request within ten (10) days),  (b) on the date such request
is  received by Lender and on the date such  payment is to be made,  no Event of
Default  shall  exist and remain  uncured,  (c) Lender  shall have  received  an
Officer's  Certificate from Borrower certifying that all Required Repairs at the
Property for which  disbursement has been requested have been completed (i) in a
good and  workmanlike  manner and (ii) in accordance  with all applicable  Legal

use or occupancy of the  Property,  (d) Lender shall have  received an Officer's
Certificate from Borrower (i) identifying each Person that supplied materials or
labor in connection with the Required  Repairs for which  disbursement  has been
requested  (ii)  stating  that each such Person has been paid in full or will be
paid in full with the funds  disbursed,  such certificate to be accompanied by a
copy of appropriate  lien waivers or other evidence of payment  satisfactory  to
Lender, (e) at Lender's option, a title search for the Property  indicating that
the  Property  is free  from  all  liens,  claims  and  other  encumbrances  not
previously  approved  by Lender and (f) Lender  shall have  received  such other

of such  disbursement.  Lender  shall be required to make only one  disbursement
from the Required Repair Account during a month and such  disbursement  shall be
made only upon  satisfaction of each condition  contained in this Section 7.2.3.
Upon  completion of all Required  Repairs in  accordance  with the terms hereof,
Lender shall  disburse to Borrower  any amounts  then  remaining in the Required
Repair Account.

     7.2.4 FAILURE TO PERFORM REQUIRED REPAIRS.  It shall be an Event of Default
under this  Agreement if (a) Borrower does not complete the Required  Repairs at
the Property by the required deadline for each repair as set forth on Schedule 3
or (b) Borrower  does not satisfy  each  condition  contained  in Section  7.2.3
hereof.  Upon the occurrence of an Event of Default,  Lender, at its option, may
withdraw all Required  Repair Funds from the Required  Repair Account and Lender
may apply  such  funds  either to  completion  of the  Required  Repairs  at the
Property or toward payment of the Debt in such order, proportion and priority as
Lender may  determine  in its sole  discretion.  Lender's  right to withdraw and
apply  Required  Repair  Funds  shall be in  addition  to all other  rights  and
remedies provided to Lender under this Agreement and the other Loan Documents.

be payable  during the next  ensuing  twelve (12) months in order to  accumulate
with  Lender  sufficient  funds to pay all such Taxes at least  thirty (30) days
prior to their respective due dates and (ii) one-twelfth (1/12) of the Insurance
Premiums that Lender  estimates  will be payable for the renewal of the coverage
afforded by the Policies upon the expiration thereof in order to accumulate with
Lender sufficient funds to pay all such Insurance  Premiums at least thirty (30)
days prior to the  expiration  of the Policies and (b) on the Closing  Date,  an
amount which,  when combined with the monthly  deposits  described in (a) above,
shall be sufficient to pay the next  installment  of Taxes and the next required
payment of Insurance  Premiums on the due date therefor (said amounts in (a) and
(b) above hereinafter  called the "Tax and Insurance Escrow Fund").  The Tax and
Insurance  Escrow  Fund,  and the  payments of interest  or  principal  or both,

aggregate  sum by Borrower to Lender.  Lender will permit the Tax and  Insurance
Escrow Fund to be applied to payments of Taxes and Insurance  Premiums  required
to be made by Borrower  pursuant to Section 5.1 hereof or to reimburse  Borrower
for such  amounts  upon  presentation  of evidence  of payment and an  Officer's
Certificate in form and substance satisfactory to Lender;  subject,  however, to

may do so  according  to any  bill,  statement  or  estimate  procured  from the
appropriate  public  office  (with  respect to Taxes) or insurer or agent  (with
respect to Insurance Premiums),  without inquiry into the accuracy of such bill,
statement  or  estimate  or into  the  validity  of any tax,  assessment,  sale,
forfeiture, tax lien or title or claim thereof. If at any time Lender determines
that the Tax and  Insurance  Escrow Fund is not or will not be sufficient to pay
the items set forth in (a) and (b) above,  Lender shall notify  Borrower of such
determination  and Borrower shall increase its monthly payments to Lender by the
amount that Lender reasonably  estimates is sufficient to make up the deficiency
at least thirty (30) days prior to delinquency of the Taxes and/or expiration of
the Policies, as the case may be.

     7.3.2 GRANT OF SECURITY  INTEREST.  Borrower  hereby  pledges,  assigns and
grants a security  interest to Lender,  as security  for payment of all sums due

subaccount  under the terms of the Custody  Agreement  on each  Payment  Date an
amount equal to one-twelfth (1/12th) of the product obtained by multiplying $.25
by the aggregate  amount of square feet of rentable  space in the Property (said
amounts  hereinafter called the "Capital Reserve Fund").  Lender will consent to
the application the Capital Reserve Fund to payment of Approved Capital Expenses
pursuant to the terms  hereof;  provided,  however,  if the Loan shall have been
accelerated or if there is an Event of Default which is continuing,  then Lender
may direct that such Capital  Reserve  Fund be applied  against the Debt in such
priority and  proportions  as Lender in its sole and absolute  discretion  shall
deem  proper.

be  cumulative  and  concurrent  and  may  be  pursued  independently,   singly,
successively,  together or  otherwise,  at such time and in such order as Lender
may determine in its sole  discretion,  to the fullest extent  permitted by law,
without impairing or otherwise affecting the other rights and remedies of Lender
permitted by law, equity or contract or as set forth herein or in the other Loan
Documents.  Without  limiting the generality of the foregoing,  Borrower  agrees
that if an Event of Default is continuing  (i) Lender is not subject to any "one
action"  or  "election  of  remedies"  law or rule and (ii) all  liens and other
rights, remedies or privileges provided to Lender shall remain in full force and
effect until Lender has exhausted all of its remedies.

     (c) Subject to the  Property  Loan  Documents,  Lender shall have the right
from  time to time to sever the Note and the other  Loan  Documents  into one or
more  separate   notes,   mortgages  and  other   security   documents  in  such
denominations  as Lender shall  determine in its sole discretion for purposes of
evidencing and enforcing its rights and remedies  provided  hereunder.  Borrower
shall  execute  and  deliver  to Lender  from time to time,  promptly  after the
request of Lender,  a severance  agreement  and such other  documents  as Lender
shall  request  in order to effect  the  severance  described  in the  preceding


                                      -32-
<PAGE>
sentence,  all in form and substance  reasonably  satisfactory to Lender. In the
event Borrower fails to execute within five (5) days, Borrower hereby absolutely
and irrevocably appoints Lender as its true and lawful attorney, coupled with an
interest,  in its name and stead to make and execute all documents  necessary or
desirable to effect the  aforesaid  severance,  Borrower  ratifying all that its
said attorney shall do by virtue thereof.

     Section 8.3 REMEDIES CUMULATIVE.  The rights, powers and remedies of Lender
under this  Agreement  shall be cumulative and not exclusive of any other right,
power  or  remedy  which  Lender  may have  against  Borrower  pursuant  to this
Agreement  or the  other  Loan  Documents,  or  existing  at law or in equity or
otherwise.   Lender's  rights,  powers  and  remedies  may  be  pursued  singly,
concurrently  or  otherwise,  at such  time  and in such  order  as  Lender  may
determine  in Lender's  sole  discretion.  No delay or omission to exercise  any
remedy,  right or power  accruing upon an Event of Default shall impair any such
remedy,  right or power or shall be construed as a waiver thereof,  but any such
remedy, right or power may be exercised from time to time and as often as may be
deemed  expedient.  A waiver of one Default or Event of Default  with respect to
Borrower  shall not be  construed  to be a waiver of any  subsequent  Default or
Event of Default by Borrower or to impair any remedy,  right or power consequent
thereon.

IX.  SPECIAL PROVISIONS
     ------------------

     Section 9.1 SALE OF NOTE AND SECONDARY MARKET TRANSACTION.

     9.1.1 COOPERATION.  At Lender's request (to the extent not already required
to be provided  by  Borrower  under this  Agreement),  Borrower,  at no cost and
expense  to  Borrower,  shall use  reasonable  efforts  to  satisfy  the  market
standards  to  which  Lender  customarily  adheres  or which  may be  reasonably
required in the  marketplace or by the Rating Agencies in connection with one or
more  sales  or   assignments   of  the  Note  or   participations   therein  or
securitizations  of rated single or  multiclass  securities  (the  "Securities")
secured by or evidencing  ownership interests in the Note and the Mortgage (each
such sale, assignment,  participation and/or securitization, a "Secondary Market
Transaction"). Without limiting the generality of the foregoing, Borrower shall,
at the request of Lender in connection with any Secondary Market Transaction, at
no cost and expense to Borrower and so long as the Loan is still outstanding:

     (a) (i) provide such  financial and other  information  with respect to the
Property,  Borrower and its Affiliates,  Manager and any tenants of the Property
in Borrower's  possession,  (ii) provide  business plans and budgets relating to
the Property and (iii) subject to the Property Loan Documents  perform or permit
or cause to be performed or permitted such site inspection, appraisals, surveys,
market   studies,   environmental   reviews  and  reports  (Phase  I's  and,  if
appropriate,   Phase  II's),   engineering   reports  and  other  due  diligence
investigations of the Property, as may be reasonably requested from time to time
by Lender or the  Rating  Agencies  or as may be  necessary  or  appropriate  in
connection with a Secondary Market Transaction or Exchange Act requirements (the
items  provided  to Lender  pursuant  to this  paragraph  (a) being  called  the
"Provided Information"),  together, if customary,  with appropriate verification
of and/or  consents to the Provided  Information  through letters of auditors or
opinions of counsel of independent attorneys acceptable to Lender and the Rating
Agencies;

     (b)  at  Borrower's  expense,  cause  counsel  to  render  opinions  as  to
non-consolidation,  fraudulent  conveyance,  true sale and true contribution and
any other opinion customary in  securitization  transactions with respect to the
Property,  Borrower and its  Affiliates,  which  counsel and  opinions  shall be
reasonably satisfactory to Lender and the Rating Agencies;

     (c) make such  representations and warranties as of the closing date of any
Secondary Market Transaction with respect to the Property, Borrower and the Loan
Documents  as  are  customarily  provided  in  such  transactions  and as may be
reasonably  requested by Lender or the Rating  Agencies and consistent  with the
facts covered by such  representations  and warranties as they exist on the date
thereof,   including  the  representations  and  warranties  made  in  the  Loan
Documents;

     (d) provide current  certificates of good standing and  qualification  with
respect to Borrower from appropriate Governmental Authorities; and

     (e)  execute  such   amendments  to  the  Loan   Documents  and  Borrower's
organizational  documents,  enter into a lock-box  or similar  arrangement  with
respect  to the  Rents and  establish  and fund such  reserve  funds  (including
reserve  funds for  deferred  maintenance  and capital  improvements)  as may be

                                      -33-
<PAGE>
requested  by Lender or the Rating  Agencies or  otherwise to effect a Secondary
Market Transaction, provided that nothing contained in this subsection (e) shall
result in a material economic change in the transaction.

Lender  shall pay all  reasonable  third  party costs and  expenses  incurred by
Lender in connection with a Secondary Market Transaction

     9.1.2 USE OF INFORMATION.  Borrower  understands that all or any portion of
the Provided  Information and the Required Records may be included in disclosure
documents  in  connection  with a  Secondary  Market  Transaction,  including  a
prospectus or private placement  memorandum (each, a "Disclosure  Document") and
may also be included in filings  with the  Securities  and  Exchange  Commission
pursuant to the Securities Act of 1933, as amended (the  "Securities  Act"),  or
the  Securities and Exchange Act of 1934, as amended (the  "Exchange  Act"),  or
provided  or  made  available  to  investors  or  prospective  investors  in the
Securities, the Rating Agencies, and service providers or other parties relating
to the Secondary Market  Transaction.  In the event that the Disclosure Document
is required to be revised,  Borrower shall cooperate with Lender in updating the
Provided  Information  or  Required  Records  for  inclusion  or  summary in the
Disclosure  Document or for other use reasonably  required in connection  with a
Secondary Market Transaction by providing all current information  pertaining to
Borrower,  Manager and the Property  necessary to keep the  Disclosure  Document
accurate  and complete in all material  respects  with respect to such  matters.
Such  disclosure  may  include  the  opinion or  judgment  of Lender or Servicer
concerning  the Provided  Information  or other matters  disclosed,  and despite
reasonable good faith efforts by Lender and/or  Servicer,  the disclosure may be
erroneous  or  incomplete.   Borrower  hereby  consents  to  any  and  all  such
disclosures of such information.

     9.1.3 BORROWER OBLIGATIONS  REGARDING DISCLOSURE  DOCUMENTS.  In connection
with a Disclosure Document, Borrower shall:

     (a) if requested by Lender,  certify in writing that Borrower has carefully
examined those portions of such Disclosure Document, pertaining to Borrower, the
Property,  the  Manager  and the  Loan,  including  applicable  portions  of the
sections  entitled  "Special  Considerations",  "Description  of the Mortgages",
"Description of the Mortgage Loans and Mortgaged Property",  "The Manager", "The
Borrower" and "Certain  Legal Aspects of the Mortgage  Loan",  and such portions
(and  portions of any other  sections  reasonably  requested  and  pertaining to
Borrower,  the  Property,  the  Manager or the Loan) do not  contain  any untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements made, in the light of the circumstances  under which they
were made, not misleading;

     (b)  indemnify (i) any  underwriter,  syndicate  member or placement  agent
(collectively,  the  "Underwriters")  retained by Lender or its issuing  company
affiliate (the "Issuer") in connection with a Secondary Market Transaction, (ii)
Lender  and  (iii)  the  Issuer  that is named  in the  Disclosure  Document  or
registration   statement   relating  to  a  Secondary  Market  Transaction  (the
"Registration  Statement"),  and  each of the  Issuer's  directors,  each of its
officers who have signed the  Registration  Statement  and each person or entity
who  controls  the Issuer or the Lender  within the meaning of Section 15 of the
Securities Act or Section 30 of the Exchange Act (collectively within (iii), the
"CCA Group"), and each of its directors and each person who controls each of the
Underwriters, within the meaning of Section 15 of the Securities Act and Section
20 of the Exchange Act (collectively,  the "Underwriter  Group") for any losses,
claims,  damages or liabilities  (the  "Liabilities")  to which Lender,  the CCA
Group or the Underwriter Group may become subject (including  reimbursing all of
them for any  legal or other  expenses  actually  incurred  in  connection  with
investigating or defending the Liabilities) insofar as the Liabilities arise out
of or are based upon any untrue  statement  or alleged  untrue  statement of any
material  fact  contained  in  any  of  the  Required  Records  or in any of the
applicable  portions of such sections of the Disclosure  Document  applicable to
Borrower,  Manager,  the Property  (but only to the extent such  information  is
supplied  by  Borrower)  or the  Loan,  or arise  out of or are  based  upon the
Borrower's  omission  or  alleged  omission  to state  therein a  material  fact
required to be stated in the  applicable  portions of such sections or necessary
in order to make the statements in the  applicable  portions of such sections in
light  of  the  circumstances   under  which  they  were  made,  not  materially
misleading,  provided, however, that Borrower shall not be required to indemnify
Lender for any  Liabilities  relating to untrue  statements  or omissions  which
Borrower  identified to Lender in writing at the time of Borrower's  examination
of such Disclosure Document; and

     (c) reimburse  any member of the CCA Group for any legal or other  expenses
reasonably incurred by such member in connection with investigating or defending
the Liabilities.

                                      -34-
<PAGE>
Borrower's  Liability  under  clause  (a) or  (b)  above  shall  be  limited  to
Liabilities arising out of or based upon any such materially untrue statement or
omission  made  therein in  reliance  upon and in  conformity  with  information
furnished  to  Lender  by or on  behalf  of  Borrower  in  connection  with  the
preparation of those portions of the Disclosure Document pertaining to Borrower,
Manager,  the Property (but only to the extent such  information  is supplied by
Borrower)  or the Loan or in  connection  with  the  underwriting  of the  debt,
including financial statements of Borrower, operating statements, rent rolls and
other  Required  Records,  environmental  site  assessment  reports and property
condition reports with respect to the Property.  The foregoing indemnity will be
in addition to any liability which Borrower may otherwise have.

     9.1.4 BORROWER  INDEMNITY  REGARDING  FILINGS.  In connection  with filings
under the Exchange Act, Borrower shall (i) indemnify  Lender,  the CCA Group and
the Underwriter Group for any Liabilities to which Lender,  the CCA Group or the
Underwriter  Group may become subject insofar as the Liabilities arise out of or
are based  upon the  Borrower's  omission  or alleged  omission  to state in the
Provided  Information or Required  Records a material fact required to be stated
by Borrower in the Provided Information or Required Records in order to make the
statements  in the Provided  Information  or Required  Records,  in light of the
circumstances  under  which  they were made not  misleading  and (ii)  reimburse
Lender,  the CCA Group or the Underwriter  Group for any legal or other expenses
actually  incurred by Lender,  CCA Group or the Underwriter  Group in connection
with defending or investigating the Liabilities.

     9.1.5 INDEMNIFICATION  PROCEDURE.  Promptly after receipt by an indemnified
party under Section 9.1.3 or 9.1.4 of notice of the  commencement  of any action
for which a claim  for  indemnification  is to be made  against  Borrower,  such
indemnified party shall notify Borrower in writing of such commencement, but the
omission to so notify the Borrower will not relieve  Borrower from any liability
that it may have to any indemnified  party  hereunder  except to the extent that
failure to notify causes prejudice to Borrower.  In the event that any action is
brought  against  any  indemnified  party,  and  it  notifies  Borrower  of  the
commencement  thereof,  Borrower  will  be  entitled,  jointly  with  any  other
indemnifying  party, to participate therein and, to the extent that it (or they)
may elect by written notice  delivered to the  indemnified  party promptly after
receiving the aforesaid  notice of  commencement,  to assume the defense thereof
with counsel  satisfactory to such  indemnified  party in its discretion.  After
notice  from  Borrower  to such  indemnified  party  under this  Section  9.1.5,
Borrower shall not be responsible  for any legal or other expenses  subsequently
incurred by such indemnified  party in connection with the defense thereof other
than reasonable costs of investigation;  provided, however, if the defendants in
any  such  action  include  both  Borrower  and an  indemnified  party,  and any
indemnified  party  shall  have  reasonably  concluded  that there are any legal
defenses  available to it and/or other  indemnified  parties that are  different
from or additional to those available to Borrower, then the indemnified party or
parties  shall have the right to select  separate  counsel to assert  such legal
defenses and to otherwise participate in the defense of such action on behalf of
such indemnified party or parties. Borrower shall not be liable for the expenses
of more than one separate  counsel unless there are legal defenses  available to
it  that  are  different  from or  additional  to  those  available  to  another
indemnified party.

     9.1.6 CONTRIBUTION. In order to provide for just and equitable contribution
in circumstances in which the indemnity  agreement provided for in Section 9.1.3
or 9.1.4 is for any reason held to be unenforceable  by an indemnified  party in
respect of any  Liabilities (or action in respect  thereof)  referred to therein
which would otherwise be  indemnifiable  under Section 9.1.3 or 9.1.4,  Borrower
shall  contribute  to the amount paid or payable by the  indemnified  party as a
result of such Liabilities (or action in respect  thereof);  provided,  however,
that no Person  guilty of  fraudulent  misrepresentation  (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution  from any
Person not  guilty of such  fraudulent  misrepresentation.  In  determining  the
amount of  contribution  to which  the  respective  parties  are  entitled,  the
following  factors  shall be  considered:  (i) the CCA  Group's  and  Borrower's
relative knowledge and access to information  concerning the matter with respect
to which the claim was asserted; (ii) the opportunity to correct and prevent any
statement or omission; and (iii) any other equitable considerations  appropriate
in the  circumstances.  Lender  and  Borrower  hereby  agree  that it may not be
equitable if the amount of such  contribution were determined by pro rata or per
capita allocation.

     9.1.7  RATING  SURVEILLANCE.  Lender  will  retain the Rating  Agencies  to
provide rating  surveillance  services on  Securities.  The pro rata expenses of
such  surveillance  will  be  paid  for by  Borrower  based  on  the  applicable
percentage  of  such  expenses  determined  by  dividing  the  then  outstanding
Principal by the then  aggregate  outstanding  amount of the pool created in the
Secondary Market Transaction which includes the Loan.

     Section 9.2 RESERVED.

     Section 9.3 RESERVED.

     Section 9.4 EXCULPATION.  Subject to the qualifications below, Lender shall
not enforce the liability and  obligation of Borrower to perform and observe the
obligations contained in the Note, this Agreement or the other Loan Documents by
any  action or  proceeding  wherein  a money  judgment  shall be sought  against
Borrower,  except that subject to the provisions of the Loan Documents governing
remedies,  Lender  may  bring a  foreclosure  action,  an  action  for  specific
performance  or any other  appropriate  action or proceeding to enable Lender to
enforce and realize upon its interest  under the Note,  this  Agreement  and the
other Loan Documents,  or any other  collateral  given to Lender pursuant to the
Loan Documents; provided, however, that, except as specifically provided herein,
any  judgment  in any such action or  proceeding  shall be  enforceable  against
Borrower only to the extent of  Borrower's  interest in the Property  Loan,  the
Property,  in the Rents and in any other collateral given to Lender, and Lender,
by accepting the Note, the Mortgage and the other Loan Documents, agrees that it
shall not sue for, seek or demand any deficiency  judgment  against  Borrower in
any such action or  proceeding  under or by reason of or under or in  connection
with the Note,  this  Agreement or the other Loan  Documents.  The provisions of
this section shall not, however, (a) constitute a waiver,  release or impairment
of any obligation evidenced or secured by any of the Loan Documents;  (b) impair
the right of Lender to name Borrower as a party  defendant in any action or suit
for foreclosure  and sale under the Loan  Documents;  (c) affect the validity or
enforceability of or any guaranty made in connection with the Loan or any of the
rights and remedies of Lender thereunder;  (d) constitute a prohibition  against
Lender commencing any other appropriate action or proceeding in order for Lender
to fully  realize  the  security  granted by the  Mortgage  or to  exercise  its
remedies against the Property; or (e) constitute a waiver of the right of Lender
to enforce the  liability  and  obligation  of  Borrower,  by money  judgment or
otherwise, to the extent of any loss, damage, cost, expense, liability, claim or
other  obligation  incurred  by  Lender  (including  attorneys'  fees and  costs
reasonably incurred) arising out of or in connection with the following:

     (i) fraud or intentional  misrepresentation by Borrower or any guarantor in
connection with the Loan;

     (ii) the gross negligence or willful misconduct of Borrower;

     (iii) the  misapplication  or  conversion  by Borrower of (A) any insurance
proceeds paid by reason of any loss, damage or destruction to the Property,  (B)
any awards or other amounts  received in connection with the condemnation of all
or a portion of the  Property,  or (C) any Rents  following an Event of Default;
and

     (iv) Borrower's indemnification of Lender set forth in Section 9.2.

Notwithstanding  anything to the  contrary in this  Agreement or any of the Loan
Documents,  (x) Lender shall not be deemed to have waived any right which Lender
may have under Sections 506(a),  506(b),  1111(b) or any other provisions of the
U.S.  Bankruptcy Code to file a claim for the full amount of the Debt secured by
the Mortgage or to require that all  collateral  shall continue to secure all of
the Debt owing to Lender in accordance with the Loan Documents, and (y) the Debt
shall be fully  recourse  to  Borrower  in the event  that:  (aa) the first full
monthly  payment of principal and interest  under the Note is not paid when due;
(bb) Borrower  fails to permit on site  inspections  of the  Property,  fails to
provide financial information,  fails to maintain its status as a single purpose
entity or fails to appoint a new  property  manager  upon the  request of Lender
after an Event of Default, each as required by, and in accordance with the terms
and provisions of, this Loan  Agreement;  (cc) Borrower fails to obtain Lender's
prior  written  consent to any  subordinate  financing or other  voluntary  lien
encumbering  the Property Loan; or (dd) Borrower fails to obtain  Lender's prior
written consent to any assignment,  transfer, or conveyance of the Property Loan
or any interest therein.

     Section 9.5  TERMINATION OF MANAGER.  If an Event of Default is continuing,
Borrower  shall,  at the request of Lender,  use good faith efforts to cause the
termination of the Management  Agreement and the replacement of the Manager with
a manager approved by Lender on terms and conditions satisfactory to Lender.

     Section 9.6 RETENTION OF SERVICER.  Lender reserves the right to retain the
Servicer  to act as its agent  hereunder  with such  powers as are  specifically
delegated  to the  Servicer  by Lender,  whether  pursuant  to the terms of this
Agreement,  the Pooling and Servicing  Agreement or the Cash Collateral  Account
Agreement  or  otherwise,  together  with such  other  powers as are  reasonably


                                      -36-

incidental  thereto.  Borrower shall pay any reasonable fees and expenses of the
Servicer  in  connection  with an  assumption  or  modification  of the  Loan or
enforcement of the Loan Documents.

approve  or  disapprove  or  to  decide  whether   arrangements   or  terms  are
satisfactory  or not  satisfactory  shall  (except as is otherwise  specifically
herein  provided)  be in the sole  discretion  of Lender  and shall be final and
conclusive.

TO ELECT A TRIAL BY JURY OF ANY ISSUE  TRIABLE  OF RIGHT BY JURY,  AND WAIVE ANY
RIGHT TO TRIAL BY JURY  FULLY TO THE  EXTENT  THAT ANY SUCH  RIGHT  SHALL NOW OR
HEREAFTER EXIST WITH REGARD TO THE LOAN DOCUMENTS, OR ANY CLAIM, COUNTERCLAIM OR
OTHER ACTION ARISING IN CONNECTION  THEREWITH.  THIS WAIVER OF RIGHT TO TRIAL BY
JURY IS GIVEN KNOWINGLY AND VOLUNTARILY BY BORROWER AND LENDER,  AND IS INTENDED
TO ENCOMPASS  INDIVIDUALLY EACH INSTANCE AND EACH ISSUE AS TO WHICH THE RIGHT TO
A TRIAL BY JURY WOULD  OTHERWISE  ACCRUE.  LENDER AND  BORROWER  ARE EACH HEREBY
AUTHORIZED  TO FILE A COPY OF THIS  PARAGRAPH IN ANY  PROCEEDING  AS  CONCLUSIVE
EVIDENCE OF THIS WAIVER.

     Section 10.8 HEADINGS. The Article and/or Section headings and the Table of
Contents in this Agreement are included herein for convenience of reference only
and shall not constitute a part of this Agreement for any other purpose.

     Section  10.9  SEVERABILITY.  Wherever  possible,  each  provision  of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid under  applicable law, such provision shall be ineffective to the extent
of such  prohibition or invalidity,  without  invalidating the remainder of such
provision or the remaining provisions of this Agreement.

     Section 10.10  PREFERENCES.  Lender shall have the continuing and exclusive
right to apply or reverse and  reapply  any and all  payments by Borrower to any
portion of the obligations of Borrower hereunder. To the extent Borrower makes a
payment or payments to Lender, which payment or proceeds or any part thereof are
subsequently invalidated,  declared to be fraudulent or preferential,  set aside
or  required  to be repaid to a trustee,  receiver  or any other party under any
bankruptcy  law, state or federal law, common law or equitable  cause,  then, to
the extent of such payment or proceeds  received,  the obligations  hereunder or
part  thereof  intended to be  satisfied  shall be revived and  continue in full
force and  effect,  as if such  payment or  proceeds  had not been  received  by
Lender.

     Section  10.11  WAIVER OF NOTICE.  Borrower  shall not be  entitled  to any
notices of any nature  whatsoever from Lender except with respect to matters for
which this  Agreement or the other Loan  Documents  specifically  and  expressly
provide for the giving of notice by Lender to Borrower  and except with  respect
to matters for which Borrower is not, pursuant to applicable Legal Requirements,
permitted  to waive the  giving  of  notice.  To the  extent  permitted  by law,
Borrower  hereby  expressly  waives the right to receive  any notice from Lender
with respect to any matter for which this  Agreement or the other Loan Documents
do not specifically and expressly  provide for the giving of notice by Lender to
Borrower.

     Section  10.12  REMEDIES  OF  BORROWER.  In  the  event  that  a  claim  or
adjudication is made that Lender or its agents,  including Servicer,  have acted
unreasonably  or  unreasonably  delayed acting in any case where by law or under
this Agreement or the other Loan  Documents,  Lender or such agent,  as the case
may be, has an obligation to act  reasonably or promptly,  Borrower  agrees that
neither  Lender  nor its  agents,  including  Servicer,  shall be liable for any
monetary damages, and Borrower's sole remedies shall be limited to commencing an
action seeking  injunctive  relief or declaratory  judgment.  The parties hereto
agree  that any  action or  proceeding  to  determine  whether  Lender has acted
reasonably shall be determined by an action seeking declaratory judgment.

     Section 10.13 EXPENSES; INDEMNITY.

     (a) Except as otherwise provided in this Agreement,  Borrower covenants and
agrees to  reimburse  Lender (or the  holder of the Loan,  as  applicable)  upon
receipt of written notice from such holder for all reasonable costs and expenses
(including reasonable  attorneys' fees and disbursements)  incurred by Lender in
connection with (i) the preparation, negotiation, execution and delivery of this
Agreement and the other Loan Documents and the  consummation of the transactions
contemplated  hereby and thereby and all the costs of furnishing all opinions by
counsel for Borrower (including any opinions requested by Lender as to any legal
matters arising under this Agreement or the other Loan Documents with respect to
the Property);  (ii)  Borrower's  ongoing  performance  of and  compliance  with
Borrower's  respective  agreements and covenants contained in this Agreement and


                                      -39-
<PAGE>
the other Loan  Documents on its part to be performed or complied with after the
Closing Date, including  confirming  compliance with environmental and insurance
requirements;  (iii)  Lender's  ongoing  performance  and  compliance  with  all
agreements  and  conditions  contained  in this  Agreement  and the  other  Loan
Documents on its part to be performed or complied  with after the Closing  Date;
(iv) the negotiation, preparation, execution, delivery and administration of any
consents,  amendments,  waivers or other modifications to this Agreement and the
other Loan Documents and any other documents or matters requested by Lender; (v)
Borrower  complying  with any  requests  made  pursuant  to  Section  9.1 hereof
(subject to the  limitations  contained  in such  section);  (vi) the filing and
recording fees and expenses, title insurance and reasonable fees and expenses of
counsel for providing to Lender all required legal  opinions,  and other similar
expenses  incurred  in  creating  and  perfecting  the  Liens in favor of Lender
pursuant to this  Agreement  and the other Loan  Documents;  (vii)  enforcing or
preserving any rights,  in response to third party claims or the  prosecuting or
defending of any action or proceeding or other litigation, in each case against,
under or affecting  Borrower,  this  Agreement,  the other Loan  Documents,  the
Property,  or any other security  given for the Loan;  and (viii)  enforcing any
obligations  of  or  collecting  any  payments  due  from  Borrower  under  this
Agreement,  the other  Loan  Documents  or with  respect to the  Property  or in
connection  with any  refinancing or  restructuring  of the credit  arrangements
provided under this Agreement in the nature of a "work-out" or of any insolvency
or bankruptcy proceedings;  provided, however, that Borrower shall not be liable
for the  payment of any such costs and  expenses to the extent the same arise by
reason of the gross  negligence,  illegal acts,  fraud or willful  misconduct of
Lender. Any costs and expenses due and payable to Lender hereunder which are not
paid by Borrower  within ten (10) days after demand may be paid from any amounts
in the Cash Collateral Account, with notice thereof to Borrower.

     (b) Borrower shall  indemnify and hold harmless Lender from and against any
and all other liabilities,  obligations,  losses, damages,  penalties,  actions,
judgments,  suits,  claims,  costs,  expenses and  disbursements  of any kind or
nature  whatsoever  (including the reasonable fees and  disbursements of counsel
for Lender in  connection  with any  investigative,  administrative  or judicial
proceeding commenced or threatened,  whether or not Lender shall be designated a
party thereto),  that may be imposed on, incurred by, or asserted against Lender
in any manner  relating  to or arising  out of (i) any breach by Borrower of its
obligations  under, or any material  misrepresentation  by Borrower contained in
this Agreement or the other Loan Documents,  (ii) the use or intended use of the
proceeds of the Loan or (iii) any information provided by Borrower, or contained
in any  documentation  approved  by  Borrower  and in any  way  relating  to the
issuance,  offering and sale of the Securities  (collectively,  the "Indemnified
Liabilities"); provided, however, that Borrower shall not have any obligation to
Lender hereunder to the extent that such Indemnified  Liabilities arise from the
gross  negligence,  illegal acts, fraud or willful  misconduct of Lender. To the
extent that the  undertaking  to  indemnify  and hold  harmless set forth in the
preceding  sentence may be  unenforceable  because it violates any law or public
policy,  Borrower shall  contribute the maximum  portion that it is permitted to
pay and satisfy  under  applicable  law to the payment and  satisfaction  of all
Indemnified Liabilities incurred by Lender.

     Section 10.14 EXHIBITS INCORPORATED. The Exhibits annexed hereto are hereby
incorporated  herein as a part of this  Agreement with the same effect as if set
forth in the body hereof.

     Section 10.15 OFFSETS, COUNTERCLAIMS AND DEFENSES. Any assignee of Lender's
interest in and to this  Agreement,  the Note and the other Loan Documents shall
take the same free and clear of all offsets, counterclaims or defenses which are
unrelated  to such  documents  which  Borrower  may  otherwise  have against any
assignor of such documents,  and no such unrelated counterclaim or defense shall
be interposed or asserted by Borrower in any action or proceeding brought by any
such assignee upon such  documents and any such right to interpose or assert any
such unrelated offset,  counterclaim or defense in any such action or proceeding
is hereby expressly waived by Borrower.

     Section 10.16 NO JOINT VENTURE OR  PARTNERSHIP.  Borrower and Lender intend
that the  relationships  created hereunder and under the other Loan Documents be
solely that of borrower  and  lender.  Nothing  herein or therein is intended to

relationship between Borrower and Lender nor to grant Lender any interest in the
Property other than that of mortgagee or lender.

Borrower or their  Affiliates  through  any media  intended to reach the general
public which refers to the Loan Documents or the financing evidenced by the Loan

     Section  10.18  WAIVER OF  MARSHALLING  OF ASSETS.  To the  fullest  extent
Borrower may legally do so,  Borrower  waives all rights to a marshalling of the
assets of Borrower,  Borrower's  partners,  if any, and others with interests in
Borrower,  and of  Borrower's  properties,  or to a sale  in  inverse  order  of

assets,  the sale in  inverse  order of  alienation,  homestead  exemption,  the
administration  of estates of  decedents,  or any other  matters  whatsoever  to
defeat,  reduce or affect the right of Lender under the Loan Documents to a sale
of the Property for the collection of the related indebtedness without any prior
or different resort for collection,  of the right of Lender or any deed of trust
trustee to the payment of the related  indebtedness  out of the net  proceeds of
the Property in preference to every other claimant whatsoever.

     Section 10.19 WAIVER OF  COUNTERCLAIM.  Borrower hereby waives the right to
assert a counterclaim,  other than a compulsory  counterclaim,  in any action or
proceeding brought against it by Lender or its agents, including Servicer.

     Section 10.20  CONFLICT;  CONSTRUCTION  OF  DOCUMENTS.  In the event of any
conflict  between the  provisions  of this  Agreement  and any of the other Loan
Documents,  the provisions of this Agreement  shall control.  The parties hereto
acknowledge  that  they were  represented  by  counsel  in  connection  with the

shall not be subject to the  principle of construing  their meaning  against the
party which drafted same.

     Section 10.21 BROKERS AND  FINANCIAL  ADVISORS.  Borrower and Lender hereby

arising  from a claim by any  Person  that  such  Person  acted on behalf of the
indemnifying party in connection with the transactions  contemplated herein. The
provisions of this Section 10.21 shall survive the expiration and termination of
this Agreement and the repayment of the Debt.

     Section 10.22 NO THIRD PARTY  BENEFICIARIES.  This  Agreement and the other
Loan  Documents  are solely for the benefit of Lender and  Borrower  and nothing
contained  in this  Agreement  or the other  Loan  Documents  shall be deemed to
confer upon anyone other than Lender and Borrower any right to insist upon or to
enforce the performance or observance of any of the obligations contained herein
or  therein.  All  conditions  to the  obligations  of  Lender  to make the Loan
hereunder are imposed  solely and  exclusively  for the benefit of Lender and no
other Person shall have standing to require  satisfaction  of such conditions in
accordance  with their terms or be entitled to assume that Lender will refuse to
make the Loan in the absence of strict compliance with any or all thereof and no
other Person shall under any circumstances be deemed to be a beneficiary of such
conditions,  any or all of which  may be  freely  waived  in whole or in part by
Lender if, in Lender's sole  discretion,  Lender deems it advisable or desirable
to do so.

     Section 10.23 PRIOR AGREEMENTS. This Agreement and the other Loan Documents
contain the entire agreement of the parties hereto and thereto in respect of the
transactions  contemplated hereby and thereby, and all prior agreements among or

acceptance  by Lender,  in its sole  discretion,  of such cure for such Event of
Default to be deemed cured.

                  Re:  Interest Rate Lock Agreement
                       ----------------------------

Gentlemen:

     BorSponsor  ("Borrower's  Sponsor") and The Capital  Company of America LLC
("Lender")  have entered into a Commitment  Letter dated as of  CmtLtrDate  (the
"Commitment Letter") whereby Lender intends, subject to the conditions set forth
therein,  to make a fixed rate permanent mortgage loan (the "Loan") to a special
purpose entity (the  "Borrower") in the  anticipated  principal  amount of up to
$PermLoanAmt  (the  "Anticipated  Loan Amount") secured by the real property and
other  assets  (the  "Property")  set  forth in the  Commitment  Letter  with an
effective  maturity  of  EffTerm  years.  Prior  to the  closing  of  the  Loan,
Borrower's Sponsor has requested Lender to rate lock (the "Rate Lock") an amount
equal to the  Anticipated  Loan Amount and to lock an interest rate (the "Locked
Loan Rate") for the Loan prior to Lender's  completion  of due  diligence on the
Property and prior to the  satisfaction of other conditions to closing set forth
in the  Commitment  Letter.  In  order to grant  Borrower's  Sponsor's  request,
Borrower's Sponsor and Lender agree as follows:

1.   Terms not otherwise defined herein or on Annex A attached hereto shall have
     the meaning set forth in the Commitment Letter.

2.   Borrower's Sponsor shall deposit with Lender an amount equal to two percent
     (2%) of the  Anticipated  Loan Amount (the  "Initial  Rate Lock  Deposit").
     Hereinafter,  the term "Rate Lock Deposit" shall mean the Initial Rate Lock
     Deposit  and any  Additional  Rate Lock  Deposit  as  hereinafter  defined.
     Subject to the  conditions  set forth  below,  the Locked  Loan Rate on the
     Anticipated  Loan Amount shall be set at (i) LoanSpread% the (" Loan Spread
     ") plus (ii) the "Benchmark  Treasury Rate". The "Benchmark  Treasury Rate"
     shall be equal to the Benchmark  Swap Rate minus the Benchmark Swap Spread.
     The "Benchmark  Swap Spread" shall be the then  prevailing bid side forward
     swap spread for EffTerm year interest rate swaps MonthsFwd  months forward.
     The  "Benchmark  Swap Rate"  shall be the then  prevailing  offer rate on a
     forward  interest  rate  swap  beginning   onExpClosDate  and  maturing  on
     EffMaturDate versus 3 month LIBOR assuming  semi-annual payments calculated
     on a 30/360  basis.  The Rate Lock shall be  executed  upon (i)  Borrower's
     Sponsor's  deposit of the Initial  Rate Lock Deposit and (ii) a request via
     telephone by  Borrower's  Sponsor to Lender  requesting  Lender to lock the
     interest rate in accordance with the terms of this Agreement.  Lender shall
     within three  business  days confirm in writing to  Borrower's  Sponsor the
     Locked Loan Rate, the Benchmark  Treasury Rate, the Benchmark Swap Rate and
     the Benchmark  Swap Spread.  The Locked Loan Rate shall be applicable  with
     respect to the  Anticipated  Loan  Amount only if the Loan is funded at any
     time from the date hereof  through the earlier of (i) 12:00 p.m.  (New York
     Time)  ExpClosDate or (ii) the  termination  of the Commitment  Letter (the
     "Rate  Lock  Period").  In  addition,  during  the term of this  Agreement,
     Borrower's Sponsor shall pay Lender in advance, a fee each month equal to 8
     basis points multiplied by the Anticipated Loan Amount.

3.   (a) If, in the good faith  opinion of Lender,  at any time  during the Rate
     Lock Period,  Lender determines that there are Losses hereunder equal to or
     greater  than 50% of the Rate  Lock  Deposit,  Borrower's  Sponsor  will be
     required,  no later  than 1:00 p.m.  (New York  Time) on the  business  day
     following  notice of any such Losses (the "Losses Payment Date") to deposit
     with Lender (by wire transfer of immediately available funds) the amount of
     such  Losses  which  amount  shall  be known as an  "Additional  Rate  Lock
     Deposit".  Borrower's  Sponsor's  failure to pay Lender the Additional Rate
     Lock Deposit by 1:00 p.m.  (New York Time) on the Losses  Payment Date will
     result in a default  hereunder and under the  Commitment  Letter and Lender
     may, at its sole  discretion,  at any time  thereafter  fully or  partially
     terminate the Rate Lock.

                  (b) If, in the good faith  opinion of Lender,  at any time, it
appears  that the  actual  principal  amount  of the Loan  will be less than the
Anticipated Loan Amount (such reduced amount, the "Revised Loan Amount"), Lender
may break the Rate Lock with respect to the difference  between the  Anticipated
Loan Amount and the Revised  Loan  Amount.  In such event,  the Locked Loan Rate
will not be applicable  to such amount,  and, in the event that there are Losses
on account of such  breakage,  Borrower's  Sponsor shall pay to Lender  Lender's
Expenses,  if any, via wire transfer within two business days following delivery
of notice by Lender of such Losses.  Failure of  Borrower's  Sponsor to pay such
Lender's  Expenses will result in a default  hereunder and under the  Commitment
Letter and/or the Loan Documents.

4.   In the event  that the Loan is  funded  in an amount at least  equal to the
     Anticipated  Loan  Amount  on or prior to the  expiration  of the Rate Lock
     Period,  neither  Borrower,  Borrower's  Sponsor  nor Lender  will have any
     obligation to the other with respect to the Rate Lock,  other than Lender's
     obligation to either return the Rate Lock Deposit to Borrower's  Sponsor or
     apply it to pay fees and expenses  associated with the closing of the Loan.
     In the event  that the Loan is  funded in an amount  which is less than the
     Anticipated  Loan  Amount,  Lender may break the Rate Lock with  respect to
     such Breakage Principal and shall apply the Rate Lock Deposit to Losses, if
     any,  which may result  therefrom and then to fees and expenses  associated
     with  closing  the Loan.  In the event  that (i) the Rate Lock  Period  has
     expired  and Lender has not yet funded the Loan or (ii) there shall exist a
     default  hereunder,  under  the  Commitment  Letter  and/or  under the Loan
     Documents,  Lender  may  break  the  entire  Rate  Lock and  Lender's  only
     obligation to Borrower's  Sponsor  and/or  Borrower  shall be to return the
     Rate Lock Deposit  after  setting off Lender's  Expenses.  If the Rate Lock
     Deposit is not sufficient to pay Lender's  Expenses  hereunder,  Borrower's
     Sponsor shall pay Lender the difference  within two business days following
     termination  of the  Rate  Lock.  Lender's  right  to  fully  or  partially
     terminate  the Rate Lock pursuant to the terms of the Agreement is absolute
     and is not  conditioned  upon the  giving  of any  notice  to  Borrower  or
     Borrower's Sponsor.

     In the event that the Loan is funded in an amount which is greater than the
Anticipated  Loan Amount,  the Locked Loan Rate will not be  applicable  to such
excess amount and the final  interest rate on the Loan will be determined as set
forth in the Commitment Letter and/or Loan Documents.

5.   Borrower's  Sponsor  acknowledges  that Losses,  if any,  sustained  due to
     breaking the Rate Lock will be related,  to a large extent, to movements in
     the Breakage  Benchmark  Treasury Rate, as well as general movements in the
     U.S. Treasury and related swap markets and any related changes to the yield
     curve.  Changes in the Breakage  Benchmark Treasury Rate will be subject to
     the then prevailing conditions of the U.S. Treasury market and related swap
     markets   which  is  subject  to   potentially   rapid  and  extreme  price
     fluctuations and varying levels of liquidity.  Therefore,  any action taken
     by Lender with  respect to breaking  the Rate Lock shall be taken by Lender
     as  promptly  as   practicable   after   taking  into   consideration   the
     circumstances  surrounding the break of the Rate Lock,  including,  but not
     limited to, the then prevailing  conditions in the U.S. Treasury market and
     the related swap markets. Because of the potentially volatile nature of the
     U.S. Treasury market and the related swap markets,  Lender has been granted
     rights to act (or not act) in its sole discretion.  Borrower's  Sponsor and
     Borrower  acknowledge  and accept Lender's right to act (or not act) in its
     sole  discretion as provided herein and waives any potential claim or cause
     of action Borrower and/or  Borrower's  Sponsor may have against Lender with
     respect  to any  action  taken (or not  taken) by  Lender  pursuant  to the
     provisions  set forth  herein.  Borrower's  Sponsor  and  Borrower  further
     acknowledge  that based upon market  conditions,  there can be no degree of
     certainty as to the rate of the Breakage  Benchmark  Treasury  Rate used to
     calculate Losses until the Rate Lock is actually  terminated by Lender.  In
     addition,  Borrower's Sponsor and Borrower acknowledge that the Anticipated
     Loan Amount is not a commitment  by Lender  regarding the final size of the
     Loan.  Such  amount  will  be  determined  according  to the  terms  of the
     Commitment Letter and/or Loan Documents.

6.   The obligations of Borrower's Sponsor and Lender pursuant to this Agreement
     are  independent of their  obligations  pursuant to the Commitment  Letter,
     even in the event of a termination of the Rate Lock.  This Agreement  shall
     in no way be  construed to be a  commitment  by Lender or any  affiliate to
     fund the Loan or purchase  or sell any  securities  on behalf of  Borrower,
     Borrower's  Sponsor  and/or any third party.  In addition,  this  Agreement
     shall in no way be construed to reduce Borrower's Sponsor and/or Borrower's
     obligations pursuant to the Commitment Letter.

7.   This  Agreement  shall  terminate upon the earlier of (i) the expiration or
     termination of the Rate Lock Period,  (ii) any event which causes  Lender's
     commitment  to fund the Loan to terminate,  as set forth in the  Commitment
     Letter,  (iii) any event which causes  Lender to terminate the Rate Lock or
     (iv) upon notice to Borrower  and/or  Borrower's  Sponsor by Lender that it
     does not  intend to proceed  with the Loan;  provided,  however,  that this
     Agreement  shall survive until all  obligations  of the parties hereto have
     been fully satisfied.

8.   This  Agreement  shall be construed in accordance  with and governed by the
     laws of the  State  of New York  applicable  to  agreements  made and to be
     performed therein, notwithstanding any choice-of-law rules to the contrary.
     The  parties  hereto  hereby  waive any and all right to a trial by jury in
     connection with any and all matters relating hereto.

9.   This Agreement may be executed in any number or counterparts, each of which
     when so  executed  shall  be  deemed  to be an  original,  but all of which
     together shall constitute one and the same instrument.

10.  Borrower's  Sponsor and Borrower may not, without the prior written consent
     of Lender,  assign,  transfer or set over to another,  in whole or in part,
     all  or  any  part  of  their  benefits,  rights,  duties  and  obligations
     hereunder.

11.  This Agreement may be amended,  changed or modified by Borrower's  Sponsor,
     Borrower  and Lender only by an  instrument  in writing  setting  forth the
     terms of such change, modification or amendment, and signed by each party.

12.  All  notices,  demands,  consents or requests  that are either  required or
     desired to be given or furnished hereunder shall be in writing and shall be
     sent to the appropriate party at the following address:  (i) if to Borrower
     and/or  Borrower's  Sponsor,  at the  address  set forth on the first  page
     hereof, Attention:   Name   and (ii) if to Lender, at the address set forth
     on the first page hereof, Attention:   Banker  with a copy of such notice
     to the same address,  Attention:  Barry M. Funt, Esq., General Counsel. Any
     such notice sent by means of telecopy shall be deemed to be received on the
     day such telecopy is sent once orally confirmed by sender by telephone.

13.  This  Agreement   constitutes  the  entire  and  final  agreement   between
     Borrower's  Sponsor and/or  Borrower and Lender with respect to the subject
     matter  hereof,   and  there  are  no  other  agreements,   understandings,
     undertakings,  representations  or warranties among the parties hereto with
     respect to the subject matter hereof except as set forth herein.

14.  Each of Borrower's Sponsor and Borrower agrees to indemnify and hold Lender
     and each of its affiliates  (including its officers,  directors,  partners,
     employees and agents) harmless against any and all losses,  claims damages,
     costs,  expenses or liabilities in connection with,  arising out of or as a
     result of the  transactions and matters referred to or contemplated by this
     Agreement,  except to the extent that it is finally  judicially  determined
     that any such loss,  claim,  damage,  cost,  expense or  liability  results
     primarily from the gross negligence or bad faith of such indemnified  party
     or any of its agents or representatives.

     If the foregoing is in accordance with your understanding of our Agreement,
please sign and return to the undersigned a counterpart  hereof,  whereupon this
Agreement and your acceptance  shall represent a binding  agreement by and among
Borrower's Sponsor, Borrower and Lender.
