     THIRD LOAN MODIFICATION AND EXTENSION AGREEMENT


     THIS THIRD LOAN MODIFICATION AND EXTENSION AGREEMENT (this "Agreement") 
is made this 12th day of November, 1997, but shall be effective as of the 
15th day of January, 1998, by and among ST. BARNABAS LIMITED PARTNERSHIP, a 
Maryland limited partnership, (hereinafter referred to as the "Borrower"); 
CONSTELLATION PROPERTIES, INC., a Maryland corporation, (hereinafter referred 
to as the "Guarantor"); and NATIONSBANK, N.A., a national banking association 
and successor-by-merger to Maryland National Bank, (hereinafter referred to 
as the "Lender").

     INTRODUCTORY STATEMENT

     A.   On August 31, 1988, the Lender extended to the Borrower a credit 
facility in the original principal amount of $30,245,000 (hereinafter 
referred to as the "Loan") to finance the development by the Borrower of 
approximately 25.03 acres of land located on Oxen Hill Road in Prince 
George's County, Maryland and known generally as "Constellation Center".  The 
terms of the Loan have previously been modified pursuant to the terms of, 
among other things, a Loan Modification Agreement and Amendment dated May 28, 
1993 executed by and between the Borrower and the Lender and a Second Loan 
Modification Agreement and Amendment dated January 14, 1995 executed by and 
among the Borrower, the Guarantor and the Lender (hereinafter referred to as 
the "Modification Agreements").

     B.   The Loan is currently evidenced by (i) an Amended and Restated 
Promissory Note dated January 12, 1995 executed by the Borrower, as maker, in 
favor of the Lender, as payee, in the principal amount of $12,024,849.58 
(such Amended and Restated Promissory Note, together with all modifications 
thereto, extensions or renewals thereof and substitutions therefor being 
hereinafter referred to as the "Office Project Note") and (ii) an Amended and 
Restated Promissory Note dated January 12, 1995 executed by the Borrower, as 
maker, in favor of the Lender, as payee, in the principal amount of 
$568,388.86 (such Amended and Restated Promissory Note, together with all 
modifications thereto, extensions or renewals thereof and substitutions 
therefor being hereinafter referred to as the "Bank Facility Note"; the 
Office Project Note and the Bank Facility Note being hereinafter sometimes 
referred to individually as a "Note" and collectively as the "Notes"). 

     C.   The Loan is currently secured by, among other things, the lien of a 
Deed of Trust dated December 31, 1986 executed by the Borrower, as grantor, 
in favor of Mark A. Merino and Joseph V. Prado, as trustees, for the benefit 
of the Lender covering the Borrower's interest in the real property known as 
"Constellation Center" and duly recorded among the Land Records of Prince 
George's County, Maryland in Liber 6596, Folio 884, as amended (i) by a First 
Amendment to Deed of Trust dated April 20, 1987 executed by and between, 
among others, the Borrower and the Lender and duly recorded among the Land 
Records of Prince George's County, Maryland in Liber 6655, folio 206, (ii) by 
a Second Amendment to Deed of Trust dated August 31, 1988 executed by and 
between, among others, the Borrower and the Lender and duly recorded among 
the Land Records of Prince George's County, Maryland in Liber 7077, folio 
586, (iii) by a Third Amendment to Deed of Trust dated September 27, 1991 
executed by and between, among others, the Borrower and the Lender and duly 
recorded among the Land Records of Prince George's County, Maryland in Liber 
8080, folio 912, and (iv) by a Fourth Amendment to Deed of Trust dated 
January 12, 1995 executed by and between, among others, the Borrower and the 
Lender and duly recorded among the Land Records of Prince George's County, 
Maryland in Liber 10013, folio 313 (such Deed of Trust, 



together with all modifications thereto, extensions or renewals thereof and 
substitutions therefor being hereinafter referred to as the "Deed of Trust"; 
all real and personal property currently remaining subject to the lien of the 
Deed of Trust being hereinafter collectively referred to as the "Property"). 

     D.   The payment and performance of all of the obligations of the Borrower
to the Lender under the Loan were unconditionally and irrevocably guaranteed by
the Guarantor pursuant to the terms of a certain Guaranty dated September 27,
1991 executed by the Guarantor in favor of the Lender (such Guaranty, together
with all modifications thereto, extensions or renewals thereof and substitutions
therefor being hereinafter referred to as the "Guaranty"). 

     E.   On this date the Borrower continues to be the owner of the Property
and the Borrower and the Guarantor acknowledge and agree that the Deed of Trust
constitutes a valid and subsisting first lien on the Borrower's fee simple
interest in the Property for the aggregate outstanding principal balance of the
Notes and interest thereon, all in accordance with the terms, covenants,
conditions and warranties of the Deed of Trust and the Notes secured thereby,
and that all of the other provisions of the same are in full force and effect. 

     F.   Pursuant to the terms of the Notes, the Loan is scheduled to mature on
January 15, 1998, and the Borrower has requested that the Lender extend the
maturity thereof. 

     G.   In order to induce the Lender to agree to the Borrower's request
hereinabove set forth, and upon the express condition that the lien of the Deed
of Trust remains a valid and subsisting first lien on the Property and that the
execution and delivery of this Agreement shall not impair the lien thereof, the
parties hereto have agreed to execute and deliver this Agreement to modify the
terms of repayment of the Loan as hereinafter more particularly set forth.

     3.   Confirmation of Lien.  The Borrower and the Guarantor hereby 
acknowledge and agree that the Property is and shall remain in all respects 
subject to the lien, charge and encumbrance of the Deed of Trust, and nothing 
herein contained, and nothing done pursuant hereto, shall adversely affect or 
be construed to adversely affect the lien, charge or encumbrance of, or 
warranty of title in, or conveyance effected by the Deed of Trust, or the 
priority thereof over other liens, charges, encumbrances or conveyances, or 
to release or adversely affect the liability of any party or parties 
whomsoever who may now or hereafter be liable under or on account of the Loan

evidence of the indebtedness evidenced and secured thereby.

     4.   Continuation of Loan Terms.  Except as otherwise expressly set 
forth below, the outstanding principal balance of the Notes shall continue to 
bear interest and to be repaid on the terms and subject to the conditions set 
forth in the Notes and the other documents evidencing and securing the Loan 
(this Agreement, the Notes, the Deed of Trust, the Guaranty, the Modification 
Agreements and all such other documents, whether currently existing or 
hereafter executed, and all modifications thereto, extensions or renewals 
thereof and substitutions therefor being hereinafter collectively referred to 
as the "Loan Documents").  All capitalized terms used but not defined in this 
Agreement shall have the meaning given to such terms in the Loan Documents.

     5.   Interest.  Except as otherwise expressly set forth below, interest 
shall continue to accrue and be payable on the Loan at the rate or rates set 
forth in the Notes.  Notwithstanding the foregoing, provided that no default 
or event of default shall have occurred hereunder or under any of the other 
Loan Documents, upon the satisfaction by the Borrower of each of the 
conditions hereinafter set forth, as determined by the Lender in its sole but 
reasonable discretion, in the event that the Borrower exercises its option to 
further extend the maturity of the Loan in accordance with the terms of 
Paragraph 7 below, and satisfies each of the conditions precedent thereto as 
more particularly set forth in Paragraph 7 hereof, the Borrower's option to 
elect to fix the interest rate under the Notes at the "Fixed LIBOR Rate" (as 
described and defined in the Notes) shall be reduced to the Adjusted LIBOR 
Rate (as defined in the Notes) plus two hundred (200) basis points per annum.:

          (a)  The Borrower shall have furnished to the Lender a current 
certified rent roll covering the Property, along with executed copies of each 
and every lease referenced therein, which shall demonstrate that not less 
than ninety percent (90%) of all of the leaseable space within the Property 
shall then be leased to, and occupied by, bona fide, third-party tenants 
acceptable to the Lender in all respects and who or which shall have 
commenced the payment of rent under such leases (hereinafter referred to 
collectively as "Qualified Leases"); and

          (b)  The Borrower shall have achieved a ratio of Projected Net 
Operating Income to Debt Service (both as hereinafter defined), on an 
annualized basis, equal to not less than 1.25 to 1.0.  For the purposes 
hereof, the term "Projected Net Operating Income" shall mean (i) the sum of 
(1) gross rental income estimated by the Lender to be realized by the 
Borrower over the twelve (12) month period immediately following the date 
when tested by the Lender from Qualified Leases of the Property (with no 
credit for any free rent and with such further adjustment as the Lender may 
require to reflect extraordinary tenant concessions) for the period in 
question, (2) common area maintenance charges estimated by the Lender to be 
received by the Borrower during the period in question by the tenants under 
such Qualified Leases, and (3) tenant reimbursements of Projected Operating 
Expenses (as hereinafter defined) estimated by the Lender to be received by 
the Borrower during such period, less (ii) Projected Operating Expenses 
estimated by the Lender to be incurred by the Borrower during the period in 
question.  In determining Projected Net Operating Income, no deduction or 
adjustment will be made for depreciation, depletion or amortization of 
assets.  The term "Projected Operating Expenses" shall mean all costs and 
expenses estimated by the Lender to be incurred by the Borrower in connection 
with the Property for such period, including without limitation, a management 
fee for the Property equal to not less than three percent (3%) of gross 
rents, plus an adjustment, if determined to be necessary by the Lender, to 
reflect costs and expenses not historically paid by the Borrower but which 
would customarily be paid by owners of similar properties in like locations.  
The term "Debt Service" shall mean the annual principal and interest payments 
required to fully amortize the Loan in equal monthly installments of 
principal and interest based on a 20 year mortgage amortization schedule 
computed at a hypothetical fixed interest rate equal to the greater of (i) 
250 basis points per annum in excess of the then current rate on 7 year 
United States Treasury Notes, as reported in the Federal Reserve Statistical 
Release H.15(519) (the "Release") for December 31, 1998 or if such day is not 
a business day, then for the first immediately preceding day for 

                                       3


which the Release reports such rate, or (ii) nine percent (9%) per annum.  

     6.   Amortization and Maturity.  Principal and interest shall be due and
payable under the Loan as follows:

          (a)  Commencing on the first day of February, 1998 and continuing 
on the same day of each and every month thereafter to maturity (as the same 
may be further extended in accordance with the terms of Paragraph 7 below), 
(i) principal shall continue to be due and payable under the Office Project 
Note in equal monthly installments of $33,053, together with accrued and 
unpaid interest on the outstanding principal balance of the Office Project 
Note, and (ii) principal shall continue to be due and payable under the Bank 
Facility Note in equal monthly installments of $2,200, together with accrued 
and unpaid interest on the outstanding principal balance of the Bank Facility 
Note; and

          (b)  Unless the maturity of the Loan shall be further extended or 
unless sooner paid, the Loan shall mature and the entire principal balance of 
the Notes, together with all accrued and unpaid interest thereon, shall be 
due and payable on January 15, 1999.  

     7.   Extension Option. The Borrower shall have one (1) option to further 
extend the maturity of the Loan, for a period of twelve (12) additional 
months, upon the express condition for the exercise of such extension option 
that each and all of the following conditions precedent shall have been 
fulfilled or complied with to the complete satisfaction of the Lender in its 
sole and absolute discretion:

          (a)  The Borrower shall have given the Lender at least thirty (30) 
days prior written notice of its intention to extend;

          (b)  The Borrower shall have paid to the Lender, at the time the 
notice required by subparagraph (a) above is given, an extension fee in an 
amount equal to one-quarter of one percent (1/4%) of the sum of (i) the then 
outstanding principal balance of the Office Project Note, and (ii) the then 
outstanding principal balance of the Bank Facility Note; 

          (c)  No default or event of default shall have occurred hereunder 
or under any of the other Loan Documents; 

          (d)  The Borrower shall have furnished to the Lender a current 
certified rent roll covering the Property dated not more than thirty (30) 
days prior to the commencement of such extension term, along with executed 
copies of each and every lease referenced therein, which shall demonstrate 
that, at the time of the exercise by the Borrower of such extension option, 
not less than ninety percent (90%) of all of the leaseable space within the 
Property shall then be leased to, and occupied by, bona fide, third-party 
tenants acceptable to the Lender in all respects under Qualified Leases and 
who or which shall have commenced the payment of rent thereunder such leases 
(hereinafter referred to collectively as "Qualified Leases"); and

          (e)  At the time of the exercise by the Borrower of such extension 
option, the Borrower shall have achieved a ratio of Projected Net Operating 
Income to Debt Service (both as hereinafter defined), on an annualized basis, 
equal to not less than 1.25 to 1.0, which shall be measured as of December 
31, 1998 on an historical basis based upon the preceding twelve (12) month 
results.  For the purposes hereof, the term "Net Operating Income" shall mean 
(i) the sum of (1) gross rental income from Qualified Leases of the Property 
(with no credit for any free rent and with such further adjustment as the 
Lender may require to reflect extraordinary tenant concessions) for the 
period in question, (2) common area maintenance charges actually paid to the 
Borrower during the period in question by the tenants under such Qualified 
Leases, and (3) tenant reimbursements of Operating Expenses (as hereinafter 
defined) actually received by the Borrower during such period, less (ii) 
Operating Expenses 

                                       4


for the period in question.  In determining Net Operating Income, no 
deduction or adjustment will be made for depreciation, depletion or 
amortization of assets.  The term "Operating Expenses" shall mean all costs 
and expenses incurred in connection with the Property for such period, 
including without limitation, a management fee for the Property equal to not 
less than three percent (3%) of gross rents, plus an adjustment, if 
determined to be necessary by the Lender, to reflect costs and expenses not 
paid by the Borrower but which would customarily be paid by owners of similar 
properties in like locations.  The term "Debt Service" shall mean the annual 
principal and interest payments required to fully amortize the Loan in equal 
monthly installments of principal and interest based on a 20 year mortgage 
amortization schedule computed at a hypothetical fixed interest rate equal to 
the greater of (i) 250 basis points per annum in excess of the then current 
rate on 7 year United States Treasury Notes, as reported in the Federal 
Reserve Statistical Release H.15(519) (the "Release") for December 31, 1998 
or if such day is not a business day, then for the first immediately 
preceding day for which the Release reports such rate, or (ii) nine percent 
(9%) per annum.  

     8.   Late Charges and Default Interest.  In the event that any payment 
due under the Loan is not received by the Lender within fifteen (15) days 
after the date such payment is due (inclusive of the date when due), the 
Borrower shall pay to the Lender on demand a late charge equal to four 
percent (4%) of such payment.  Moreover, upon the occurrence of an event of 
default hereunder, under the Notes or under any of the other Loan Documents 
(beyond any applicable period to cure), the unpaid principal balance of the 
Notes shall bear interest thereafter until such event of default is cured at 
a rate which is at all times equal to four percent (4%) per annum in excess 
of the rate or rates of interest otherwise payable under the Loan.

     9.   Prepayment.  The Borrower shall have the right to prepay the Loan 
in full or in part, at any time and from time to time, upon ten (10) days 
prior written notice to the Lender.  With respect to any portion of the Loan 
that is bearing interest at a Floating Rate (as defined in the Notes), such 
portion of the Loan may be prepaid in full or in part without premium or 
penalty.  If any portion of the Loan bearing interest at a Fixed Rate (as 
defined in the Notes) is prepaid in full or in part for any reason 
whatsoever, other than as a result of the application of insurance or 
condemnation proceeds in accordance with the terms of the Deed of Trust, the 
Borrower shall pay to the Lender a prepayment fee calculated in accordance 
with the terms of the Notes.  All payments made on account of the Loan shall 
be applied first to any late charges then due hereunder, second to the 
payment of any prepayment penalty then due in accordance with the terms of 
the Notes, third to the payment of all accrued and unpaid interest then due 
under the Loan and the remainder, if any, shall be applied to the unpaid 
principal balance of the Loan, with application first made to all principal 
installments then due under the Loan, next to the outstanding principal 
balance due at maturity and thereafter to the unpaid principal installments 
in the inverse order of maturity.  

         10.   Extension Fees and Expenses.  In consideration of the Lender's 
agreement to modify and extend the Loan and in addition to the payments of 
principal and interest required above, the Borrower shall pay to the Lender 
upon the execution and delivery of this Agreement a non-refundable extension 
fee in the amount of $28,249.91.  In addition, the Borrower and the Guarantor 
covenant and agree to pay all other fees, costs, charges and expenses 
incurred by the Lender in connection with the preparation of this Agreement 
and the modification of the Loan, including without limitation, the Lender's 
reasonable attorneys' fees and all recording costs.         

         11.   Additional Events of Default.  In addition to those events of 
default specifically enumerated in the Notes, the Deed of Trust, and/or any 
of the other Loan Documents, the failure of the Borrower or the Guarantor to 
comply with the terms of any covenant or agreement contained herein shall 
constitute an event of default and shall entitle the Lender to exercise all 
rights and remedies provided in the Notes and the Deed of Trust, as well as 
all other rights and remedies provided to the Lender under the terms of any 
of the other Loan Documents as a result of the occurrence of the same.

         12.   Release of Claims.  The Borrower and the Guarantor, for 
themselves and for each of their 

                                       5


respective successors and assigns, hereby release and waive all claims and/or 
defenses they now or hereafter may have against the Lender and its successors 
and assigns on account of any occurrence relating to the Loan, the Loan 
Documents and/or the Property which accrued prior to the date hereof, 
including, but not limited to, any claim that the Lender (a) breached any 
obligation to the Borrower and/or the Guarantor in connection with the Loan, 
(b) was or is in any way involved with the Borrower and/or the Guarantor as a 
partner, joint venturer, or in any other capacity whatsoever other than as a 
lender, (c) failed to fund any portion of the Loan or any other sums as 
required under any document or agreement in reference thereto, or (d) failed 
to timely respond to any offers to cure any defaults under any document or 
agreement executed by the Borrower, the Guarantor or any third party or 
parties in favor of the Lender.  This release and waiver shall be effective 
as of the date of this Agreement and shall be binding upon the Borrower and 
the Guarantor and each of their respective successors and assigns, and shall 
inure to the benefit of the Lender and its successors and assigns.  The term 
"Lender" as used herein shall include, but shall not be limited to, its 
present and former officers, directors, employees, agents and attorneys. 

         13.   Ratification of Guaranty.  The Guarantor hereby covenants and 
agrees with the Lender that the execution of this Agreement does not and 
shall not in any manner affect its obligations and liabilities under the 
Guaranty and that the Guaranty remains in full force and effect.  The 
Guarantor hereby unconditionally and irrevocably guarantees to the Lender the 
due and punctual payment and performance of all obligations of the Borrower 
arising out of or connected with this Agreement as if the same were set forth 
fully in the Guaranty at the time of the execution thereof.

hereby, the parties hereto ratify and confirm each and every provision of the 
Notes, the Deed of Trust, the Guaranty and each of the other Loan Documents

conditions in the Notes or in any of the other Loan Documents conflict in any 
way with the terms and provisions hereof, the terms and provisions hereof 
shall prevail.  The parties hereto covenant and agree that the execution of 
this Agreement is not intended to and shall not cause or result in a novation 
with regard to the Notes, the Deed of Trust, the Guaranty and/or the other 
Loan Documents and that the existing indebtedness of the Borrower to the 
Lender evidenced by the Notes is continuing, without interruption, and has 
not been discharged by a new agreement.  

         15.   Entire Agreement.  NO STATEMENTS, AGREEMENTS OR 
REPRESENTATIONS, ORAL OR WRITTEN, WHICH MAY HAVE BEEN MADE TO THE BORROWER OR 
THE GUARANTOR OR TO ANY EMPLOYEE OR AGENT OF THE BORROWER OR THE GUARANTOR,

LENDER'S BEHALF, WITH RESPECT TO THE MODIFICATION AND EXTENSION OF THE LOAN, 
SHALL BE OF ANY FORCE OR EFFECT, EXCEPT TO THE EXTENT STATED IN THIS 
AGREEMENT, AND ALL PRIOR AGREEMENTS AND REPRESENTATIONS WITH RESPECT TO THE 
MODIFICATION AND EXTENSION OF THE LOAN ARE MERGED HEREIN.
