perform each and every obligation under the Loan Documents, as specifically
modified by this Agreement, and any other loan documents executed on or about

specifically modified by this Agreement, remain in full force and effect and,
together with any New Loan Documents, represent legal, valid and binding
obligations of Buyer and New Principal, as applicable, enforceable against Buyer
and New Principal, as applicable, in accordance with their terms. Buyer and New
Principal agree that this Agreement does not diminish, impair, release or

the liens and security interests encumbering the Property granted Lender by the
Loan Documents and the New Loan Documents.

16. NONWAIVER. The parties hereto acknowledge and agree that (a) any
performance or non-performance of the Loan Documents prior to the date of this
Agreement does not affect or diminish Lender's ability to require future
compliance with the Loan Documents, and (b) in the future, Lender will require
strict compliance with and performance of the Loan Documents. Nothing contained
herein shall be construed as a waiver of any of Lender's rights or remedies with
respect to any default under this Agreement or any Loan Document.

17. BANKRUPTCY OF BUYER OR NEW PRINCIPAL. Buyer covenants and agrees that in the
event Buyer shall (i) file any petition with any bankruptcy court or be the
subject of any petition under the United States Bankruptcy Code (11 U.S.C.
Section 101 et seq., the "Code"), (ii) file or be the subject of any petition
seeking any reorganization, arrangement, composition, readjustment, liquidation,
dissolution, or similar relief under any present or future federal or state act
or law relating to bankruptcy, insolvency, or other relief for debtors, (iii)
have sought or consented to or acquiesced in the appointment of any trustee,
receiver, conservator, or liquidator, or (iv) be the subject of any order,
judgment, or decree entered by any


                                       10

<PAGE>

court of competent jurisdiction approving a petition filed against such party
for any reorganization, arrangement, composition, readjustment, liquidation,
dissolution, or similar relief under any present or future federal or state act
or law relating to bankruptcy, insolvency, or relief for debtors, Lender shall
thereupon be entitled, and Buyer irrevocably consents, to the entry of an order
by a bankruptcy court granting to Lender relief from any automatic stay imposed
by Section 362 of the Code, or otherwise, on or against the exercise of the
rights and remedies otherwise available to Lender as provided in the Loan
Documents, this Agreement or as otherwise provided by law or in equity, and
Buyer irrevocably waives its right to object to, attempt to enjoin or otherwise
interfere with such relief and the exercise and enforcement by Lender of its
rights and remedies following entry of such order. Without limiting the
generality of the immediately preceding sentence, Buyer agrees that Lender will
be entitled to and it consents to immediate relief from the automatic stay
imposed by the Code to allow Lender to take any and all actions necessary,
desirable or appropriate to enforce any rights Lender may have under the Loan
Documents, including, but not limited to, the right to possession of the
Property, collection of rents, and/or the commencement or continuation of an
action to foreclose Lender's liens and security interests. Buyer further agrees
that the filing of any petition for relief under the Code which postpones,
prevents, delays or otherwise hinders Lender's efforts to collect the amounts
due under the Note or to liquidate any of the collateral therefor shall be
deemed to have been filed in bad faith and, therefore, shall be subject to
prompt dismissal or conversion to a liquidation case under the Code upon motion
therefor by Lender. Further, Buyer agrees that it will not seek, apply for or
cause the entry of any order enjoining, staying, or otherwise prohibiting or
interfering with Lender's obtaining an order granting relief from the automatic
stay and enforcement of any rights which Lender may have under the Loan
Documents, including, but not limited to, Lender's right to possession of the
Property, collection of rents and/or the commencement or continuation of an
action to foreclose Lender's liens and security interests under the Loan
Documents.

     New Principal covenants and agrees that in the event New Principal shall
(i) file any petition with any bankruptcy court or be the subject of any
petition under the Code, (ii) file or be the subject of any petition seeking any
reorganization, arrangement, composition, readjustment, liquidation,
dissolution, or similar relief under any present or future federal or state act
or law relating to bankruptcy, insolvency, or other relief for debtors, (iii)
have sought or consented to or acquiesced in the appointment of any trustee,
receiver, conservator, or liquidator, or (iv) be the subject of any order,
judgment, or decree entered by any court of competent jurisdiction approving a
petition filed against such party for any reorganization, arrangement,
composition, readjustment, liquidation, dissolution, or similar relief under any
present or future federal or state act or law relating to bankruptcy,
insolvency, or relief for debtors, Lender shall thereupon be entitled, and New
Principal irrevocably consents, to the entry of an order by a bankruptcy court
granting to Lender relief from any automatic stay imposed by Section 362 of the
Code, or otherwise, on or against the exercise of the rights and remedies
otherwise available to Lender as provided in the Loan Documents, this Agreement
or as otherwise provided by law or in equity, and New Principal irrevocably
waives its right to object to, attempt to enjoin or otherwise interfere with
such relief and the exercise and enforcement by Lender of its rights and
remedies following entry of such order. Without limiting the generality of the
immediately preceding sentence, New Principal agrees that Lender will be
entitled to and it hereby consents to immediate relief from the automatic stay
imposed by the Code to allow Lender to take any and all actions necessary,
desirable or appropriate to enforce any rights Lender may have under the Loan
Documents, including, but not limited to, the right to possession of the
Property, collection of rents, and/or the commencement or continuation of an
action to foreclose Lender's liens and security interests. New Principal further
agrees that the filing of any petition for relief under the Code which
postpones, prevents, delays or otherwise hinders Lender's efforts to collect the
amounts due under the Note or to liquidate any of the collateral therefor shall
be deemed to have been filed in bad faith and, therefore, shall be subject to
prompt dismissal or conversion to a liquidation case under the Code upon motion
therefor by Lender. Further, New Principal agrees that it will not seek, apply
for or cause the entry of any order enjoining, staying, or otherwise prohibiting
or interfering with Lender's obtaining an order granting relief from the
automatic stay and enforcement of any rights which Lender may have


                                       11

<PAGE>

under the Loan Documents, including, but not limited to, Lender's right to
possession of the Property, collection of rents and/or the commencement or
continuation of an action to foreclose Lender's liens and security interests
under the Loan Documents.

18. COMPLIANCE WITH INTEREST LAW. It is the intention of the parties hereto to
conform strictly to any present or future law which has application to the
interest and other charges under the Loan Documents (the "Interest Law").
Accordingly, notwithstanding anything to the contrary in the Loan Documents, the
parties hereto agree that the aggregate amount of all interest or other charges
taken, reserved, contracted for, charged or received under the Loan Documents or
otherwise in connection with the Loan shall under no circumstances exceed the
maximum amount of interest allowed by the Interest Law. If any excess interest
is provided for in the Loan Documents, then any such excess shall be deemed a
mistake and canceled automatically and, if theretofore paid, shall be credited
against the indebtedness evidenced and secured by the Loan Document (the
"Indebtedness") (or if the Indebtedness shall have been paid in full, refunded
by Lender), and the effective rate of interest under the Loan Documents shall be
automatically reduced to the maximum effective contract rate of interest that
Lender may from time to time legally charge under the then applicable Interest
Law with respect to the Loan. To the extent permitted by the applicable Interest
Law, all sums paid or agreed to be paid to Lender for the use, forbearance or
detention of the Indebtedness shall be amortized, prorated, allocated and spread
throughout the full term of the Loan.

19. FURTHER ASSURANCES. The parties hereto agree to do any act or execute any
additional documents required by Lender, from time to time, to correct errors in
the documenting of the Transfer and Assumption, to effectuate the purposes of
this Agreement or to better assure, convey, assign, transfer, perfect or confirm
unto Lender the property and rights intended to be given it in the Loan
Documents and the New Loan Documents.

20. LIABILITY. If any party hereto consists of more than one person, the
obligations and liabilities of each such person hereunder shall be joint and
several. This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective heirs, legal representatives, successors and
assigns forever.

21. SEVERABILITY. If any term, covenant or condition of this Agreement is held
to be invalid, illegal or unenforceable in any respect, this Agreement shall be
construed without such term, covenant or condition and the validity or
enforceability of the remaining terms, covenants or conditions shall not in any
way be affected.

22. APPLICABLE LAW; JURISDICTION. This Agreement shall be governed and construed
in accordance with the laws of the state in which the Property is located. The
parties hereto submit to personal jurisdiction in the state courts located in
said state and the federal courts of the United States of America located in
said state for the enforcement of any obligations hereunder and waive any and
all personal rights under the law of any other state to object to jurisdiction
within such state for the purposes of any action, suit, proceeding or litigation
to enforce such obligations.

23. NO RESTRICTIONS ON PERFORMANCE. The execution and delivery of this Agreement
and compliance with the provisions hereof, will not conflict with, or constitute
a breach of or a default under any agreement or other instrument to which any
party hereto is a party or by which it is bound.

24. DEFINITIONS. Unless the context clearly indicates a contrary intent or
unless otherwise specifically provided herein, words used in this Agreement
(including pronouns) shall include the corresponding masculine, feminine or
neuter forms, and the singular form of such words shall include the plural and

deemed to be


                                       12

followed by the phrase, "without limitation." The words "herein", "hereby",
"hereof", and "hereunder" shall each be deemed to refer to this entire Agreement
and not to any particular paragraph, article or section hereof. Not withstanding
the foregoing, if any law is amended so as to broaden the meaning of any term
defined in it, such broader meaning shall apply subsequent to the effective date
of such amendment. Where a defined term derives its meaning from a statutory
reference, any regulatory definition is broader than the statutory reference and
any reference or citation to a statute or regulation shall be deemed to include
any amendments to that statute or regulation and judicial and administrative
interpretations of it.

25. SECURITIES ACT OF 1933. Neither Seller nor Buyer nor any agent acting for
any of them has offered the Note or any similar obligation for sale to or
solicited any offers to buy the Note or any similar obligation from any person
or party other than Lender, and neither Seller nor Buyer nor any agent acting
for any of them will take any action which would subject the sale of the Note to
the provisions of Section 5 of the Securities Act of 1933, as amended.

26. COMPLIANCE WITH ERISA. As of the date of this Agreement, neither Seller,
Buyer nor New Principal maintains any employee benefit plan which require
compliance with ERISA. If at any time Seller, Buyer or New Principal shall
institute any employee benefit plans, they shall at all times comply with the
requirements of ERISA.

27. SOLE DISCRETION OF LENDER. Wherever pursuant to this Agreement, Lender
exercises any right given to it to approve or disapprove, or any arrangement or
term is to be satisfactory to Lender, Lender's decision to approve or disapprove
or to decide that arrangements or terms are satisfactory or not satisfactory
shall be in the sole and absolute discretion of Lender and shall be final and
conclusive, except as may be otherwise expressly and specifically provided

Agreement are for convenience of reference only and are not to be construed as

each of which shall be deemed to be an original and all of which when taken
together shall constitute one and the same Agreement.

30. INTEGRATION, SURVIVAL. This Agreement, any New Loan Documents, and the Loan
Documents embody the entire agreement by and between the parties hereto with
respect to the Loan, and any and all prior correspondence, discussions or
negotiations are deemed merged therein. Except as otherwise specifically
provided herein, all obligations of any party contained in this Agreement, the
New Loan Documents or the Loan Documents shall survive the Closing, and Lender
hereby preserves all of its rights against all persons or entities and all
collateral securing the Loan, including, without limitation, the Property.

31. NO ORAL CHANGE. This Agreement, and any provisions hereof, may not be
modified, amended, waived, extended, changed, discharged or terminated orally or
by any act or failure to act on the part of any party hereto, but only by an
agreement in writing signed by the party against whom enforcement of any
modification, amendment, waiver, extension, change, discharge or termination is
sought. In addition, nothing contained in any document submitted for Lender's
review, including, without limitation any organizational documents of Buyer, New
Principal or any of their general partners, managers/members or officers, shall
modify, amend, waive, extend, change, discharge or terminate any term or
provision of the Loan Documents or constitute Lender's consent to any matter in
the Loan Documents requiring Lender's consent unless and until such time, if
any, as an agreement specifically


                                       13

<PAGE>

allowing such modification, amendment, waiver, extension, change discharge or
termination or consenting to such matter has been executed in writing by Lender.

or other communication required or permitted hereunder shall be in writing and

33. WAIVER OF JURY TRIAL. THE PARTIES HERETO KNOWINGLY, VOLUNTARILY AND
INTENTIONALLY WAIVE ANY RIGHT THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY
LITIGATION BASED ON THE LOAN OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS
AGREEMENT, THE NEW LOAN DOCUMENTS, OR THE LOAN DOCUMENTS, OR ANY COURSE OF
CONDUCT, COURSE OF DEALING, STATEMENT (WHETHER VERBAL OR WRITTEN) OR ACTION OF
ANY PARTY HERETO. THIS PROVISION IS A MATERIAL INDUCEMENT FOR LENDER'S CONSENT
TO THE TRANSFER AND ASSUMPTION.

34. INSURANCE. At all times Buyer shall comply with all terms of the Loan
Documents, including without limitation, the insurance requirements of the
Security Instrument. Although the Lender may accept certain evidence of
insurance for purposes of closing this Transfer and Assumption, Lender or its
servicer may at any time and from time to time request additional insurance
information from Buyer to ensure or monitor Buyer's compliance with the
insurance provisions of the Security Instrument and may request that Buyer
provide such coverages as Lender or its servicer may require consistent with the
terms of the Security Instrument. By entering into this Agreement, Lender
specifically does not waive or modify any of the insurance requirements under
the Security Instrument nor any of the remedies provided therein for failure to
secure such required insurance coverage.

the Property and the assumption of the Loan, including, without limiting the
generality of the foregoing, whether the acquisition of the Property and
assumption of the Loan will comply with the requirements of Section 1031 of the
Internal Revenue Code or whether the Buyer's and New Principal's investment in
the Property is suitable, but instead Buyer and New Principal have obtained such
tax, legal and investment advice as to the effect of Buyer's acquisition of the
Property and assumption of the Loan from their own legal and other financial
advisors.

     All of the membership interests of Buyer ("INTERESTS") are currently owned
by CDECRE, Inc., an Illinois corporation ("ACCOMMODATOR"), which is wholly owned
by Chicago Deferred Exchange Corporation. The Property has been indirectly
acquired by Accommodator, as exchange accommodation titleholder, to effect a
reverse like-kind exchange under Section 1031 of the Internal Revenue Code and
Rev. Proc. 2000-37, 2000-2 C.B. 308. This arrangement is described in a
Qualified Exchange Accommodation Agreement of even date herewith, between
Accommodator and New Principal. Following the disposition by New Principal of
certain relinquished property, Accommodator will transfer all of the Interests
to New Principal.

     In order to qualify for "like-kind" treatment under Revenue Procedure
2000-37, the disposition of the relinquished property and the transfer of the
Interests to New Principal must occur on or before 180 days following the
acquisition by Buyer of the Property. The Qualified Exchange Accommodation
Agreement also provides that the right to cause the Accommodator to complete the
transfer of the Interests to New Principal prior to the expiration of the 180
day period, and if New Principal does not exercise such right during the 180-day
exchange period, Accommodator will transfer the Interests to New Principal on or
before the expiration of the 180 days period.

     Also, as part of the exchange transaction, the acquisition of the Property
by Buyer has been financed using the proceeds of a loan made by New Principal to
Accommodator and Buyer ("ACQUISITION LOAN"). The obligations of Accommodator
under the Acquisition Loan are evidenced by a Promissory Note ("ACCOMMODATION
NOTE") made and given by Accommodator and Buyer of even date herewith in the
principal amount of the Acquisition Loan. The obligations of Accommodator and
Buyer under the Acquisition Loan are secured by an assignment to New Principal
by Accommodator of all of the Interests pursuant to that certain Pledge and
Security Agreement dated of even date herewith ("PLEDGE AGREEMENT"). The
Acquisition Loan will be repaid in full at the time the Interests are
transferred to New Principal. Prior to such transfer, all or substantially all
of the net revenue of the Property will be paid to New Principal as interest
under the Acquisition Loan.

     The failure by any one of Assuming Borrower, New Principal and/or
Accommodator to cause the transfer of Interests to occur within the 180 day
period shall constitute an Event of Default under the Loan Documents. Further,
any assignment or pledge or other transfer New Principal's interests under the
Accommodation Note or the Pledge Agreement shall constitute an Event of Default
under the Loan Documents. Buyer shall deliver written notice to Lender
acknowledging the date that such Exchange


                                       16

Transfer occurred ("EXCHANGE NOTICE"). Furthermore, Buyer shall include all
documents evidencing and documenting the transfer of Interests with the Exchange
Notice. Furthermore, in connection with the delivery of the Exchange Notice,
Buyer and New Principal shall deliver a certificate to Lender, in a form
acceptable to Lender in its reasonable discretion, whereby Buyer and New
Principal ratify and reaffirm all of their respective obligations under the Loan
Documents and upon receipt of the items referred to herein, the Lender will
consent to such transfer of Interests. Buyer shall pay, or cause to be paid at
closing, all Lender's costs and expenses of Lender including reasonable
attorneys fees for the transfer of Interests.

37. ACKNOWLEDGEMENT OF LIMITED LIABILITY OF ACCOMMODATOR. Notwithstanding any
provisions of these Loan Documents to the contrary ("ACCOMMODATOR"), is acting
as an exchange Accommodator titleholder in connection with a like-kind exchange
under IRC Section 1031 and Revenue Procedure 2000-37 for the benefit of the New
Principal. As an Accommodator party, the general credit of Accommodator is not
obligated or available for the payment of the indebtedness secured by the Loan
Documents. Lender will not look to Accommodator or Accommodator's directors,
officers, and employees with respect to the indebtedness evidenced by the Loan
Documents or any covenant, stipulation, promise, indemnity, agreement or
obligation contained herein. The Lender will not seek a deficiency or other
money judgment against Accommodator or Accommodator's member's, directors,
officers, and employees and will not institute any separate action against
Accommodator by reason of any default that may occur in the performance of any
of the terms and conditions of the Loan Documents between Buyer and Lender. This
agreement on the part of the Lender shall not be construed in any way so as to
effect or impair the lien of the Loan Documents or the Lender's right to
foreclose hereunder as provided by law or foreclosure proceedings or other
enforcement of payment of the indebtedness secured hereby out of and from the
security given therefore.

certified copies of such insurance policies and original certificates of
insurance signed by an authorized agent evidencing such insurance satisfactory
to Mortgagee. Mortgagor shall renew all such insurance and deliver to Mortgagee
certificates evidencing such renewals at least thirty (30) days before any such
insurance shall expire. Without limiting the required endorsements to insurance

or deliver and furnish to Mortgagee the policies of insurance required by this
Mortgage or evidence of their renewal as required herein, Mortgagee may, but
shall not be obligated to, procure such insurance and Mortgagor shall pay all

forfeiture or diminution of the Property or any part thereof or any interest of
Mortgagee therein, and (c) prior to the earlier of the commencement of such
contest or the delinquency date of the asserted tax or assessment, Mortgagor
deposits in the Impound Account (as hereinafter defined) an amount reasonably

assessment and a reasonable additional sum to cover possible interest, costs and

insurance premiums with respect to the Property at least one (1) month prior to

of the amount of the annual premiums that will next become due and payable on
insurance policies which Mortgagor is required to maintain. hereunder, each as

valuation, sale, forfeiture, tax lien or title or claim thereof. No interest on
funds contained in the Impound Account shall be paid by Mortgagee to Mortgagor

                    on the Impound Account shall be solely for the account of
Mortgagee. If the total funds in the Impound Account shall exceed the amount of
payments actually applied by Mortgagee for the purposes of the Impound Account,
such excess may be credited by Mortgagee on subsequent payments to be made
hereunder or, at the option of Mortgagee, refunded to Mortgagor. If, however,
the Impound Account shall, not contain sufficient funds to pay the sums required
when the same shall become due and payable, Mortgagor shall, within ten (1,0)

     1.8. Security Interest In Reserves. (a) As additional security for the
payment and performance by Mortgagor of all duties, responsibilities and
obligations under the Note and the other Loan Documents, Mortgagor hereby
unconditionally and irrevocably assigns, conveys, pledges, mortgages, transfers,
delivers, deposits, sets over and confirms unto. Mortgagee, and hereby grants to
Mortgagee a security interest in all sums on deposit or due under this Mortgage
and the other Loan Documents including, without limitation, (i) the Impound
Account, the TILC Reserve, and, to the extent set forth on Exhibit C attached
hereto, any Repair and Remediation Reserve, and any other reserve set forth on
Exhibit C attached hereto (collectively, the "Reserves"), (ii) the accounts into
which the Reserves have been deposited, (iii) all insurance on said accounts,
(iv) all accounts, contract rights and general intangibles or other rights and
interests pertaining thereto, (v). all sums now or hereafter therein or
represented thereby, (vi) all replacements, substitutions or proceeds thereof,
(vii) all instruments and documents now or hereafter evidencing the Reserves or
such accounts, (viii) all powers, options, rights, privileges and immunities
pertaining to the Reserves (including the right to make withdrawals therefrom),
and (ix) all proceeds of the foregoing. Mortgagor hereby authorizes and consents
to the account into which the Reserves have been deposited being held in
Mortgagee's name or the name of any entity servicing the Note for Mortgagee and
hereby acknowledges and agrees that Mortgagee, or at Mortgagee's election, such
servicing agent, shall have exclusive control over said account. Notice of the
assignment and security interest granted to Mortgagee herein may be delivered by
Mortgagee at any time to the financial institution wherein the Reserves have
been established, and Mortgagee, or such servicing entity, shall have possession
of all passbooks or other evidences of such accounts. Mortgagor hereby holds
Mortgagee harmless with respect to all risk of loss regarding amounts on deposit
in the Reserves, except to the extent that any such loss is caused by the gross
negligence or intentional misconduct of Mortgagee. Mortgagor hereby knowingly,
voluntarily and intentionally stipulates, acknowledges and agrees that the
advancement of the funds from the Reserves as set forth herein is at Mortgagor's
direction and is not the exercise by Mortgagee of any right of set off or other
remedy upon a default. If a default shall occur hereunder or under any other of
the Loan Documents which is not cured within any applicable grace or cure
period, then, for so long as such default is continuing, Mortgagee may, without
notice or demand on Mortgagor, at its option: (A) withdraw any or all of the
funds (including, without limitation, interest) then remaining in the Reserves
and apply the same, after deducting all costs and expenses of safekeeping,
collection and delivery (including, but not


                                      -18-

<PAGE>

limited to, attorneys fees, costs and expenses) to the indebtedness evidenced

in such manner or as Mortgagee shall deem appropriate in its sole discretion,
and the excess, if any, shall be paid to Mortgagor, (B) exercise any and all
rights and remedies of a secured party under any applicable Uniform Commercial
Code, or (C) exercise any other remedies available at law or in equity. No such
use or application of the funds contained in the Reserves shall be deemed to
cure any Event of Default hereunder.

          (b) The Reserves are solely for the protection of Mortgagee and entail
no responsibility on Mortgagee's part beyond the payment of the respective costs
and expenses in accordance with the terms thereof and beyond the allowing of due
credit for the sums actually received. Upon assignment of this Mortgage by
Mortgagee, any funds in the Reserves shall be turned over to the assignee and
any responsibility of Mortgagee, as assignor, with respect thereto shall
terminate. The Reserves shall not, unless otherwise explicitly required by
applicable law, be or be deemed to be escrow or trust funds, but, at Mortgagee's
option and in Mortgagee's discretion, may either be held in a separate account
or be commingled by Mortgagee with the general funds of Mortgagee. Upon full
payment of the indebtedness secured hereby in accordance with its terms (or if
earlier, the completion of the applicable conditions to release of each Reserve
to Mortgagee's satisfaction) or at such earlier time as Mortgagee may elect, the
balance in the Reserves then in Mortgagee's possession shall be paid over to
Mortgagor and no - other party shall have any right or claim thereto.

          (c) Any amounts received by Mortgagee from Mortgagor may be invested
by Mortgagee (or its servicer) for its benefit, and Mortgagee shall not be
obligated to pay, or credit, any interest earned thereon to Mortgagor except as
may be otherwise specifically provided in this Mortgage.

     1.9. Casualty and Condemnation Mortgagor shall give Mortgagee prompt
written notice of the occurrence of any casualty affecting, or the institution:
of any proceedings for eminent domain or for the condemnation of, the Property
or any portion thereof (collectively, an "Insured Event"). All insurance
proceeds on the Property, and all causes of action, claims, compensation, awards
and recoveries for any damage, condemnation or taking of all or any part of the
Property or for any damage or injury to it for any loss or diminution in value
of the Property, are hereby assigned-to and shall be paid to Mortgagee.
Mortgagee may participate in any suits or proceedings relating to any such
proceeds, causes of action, claims, compensation., awards or recoveries and
Mortgagee is hereby authorized, in its own name or in Mortgagor's name, to
adjust any loss covered by insurance or any condemnation claim or cause of
action, and to settle or compromise any claim or cause of action in connection
therewith, and Mortgagor shall from tune to time deliver to Mortgagee any
instruments required to permit such participation; provided, however, that
Mortgagee shall not have the right to participate in the adjustment of any loss
which is not in excess of the lesser of (i) ten percent (10%) of the then
outstanding principal balance of the Note, and (ii) $400,000.00. Provided no
default is then continuing hereunder or under any of the other Loan Documents
and no event has occurred which, with the giving of notice or the passage of
time or both, would constitute a default hereunder or under any of the other
Loan Documents, Mortgagee shall apply any sums received by it under this Section
first to the payment of all of its costs and expenses (including, but not


                                      -19-

<PAGE>

limited to reasonable legal fees and disbursements) incurred in obtaining those
sums, and then, as follows:

          (a) In the event that Mortgagee receives insurance proceeds or
condemnation awards upon the occurrence of an Insured Event in an amount excess
of the lesser of (i) ten percent 10%) of the then outstanding principal balance
of the Note, and (ii) $400.,000.00 (collectively, the "Threshold Amount"),
Mortgagor shall repair or restore the Property, and Mortgagee shall, to the
extent such insurance proceeds or condemnation awards are available for such
purpose under the provisions of this Section 1.09, disburse to Mortgagor the
amount paid or incurred by Mortgagor as a result of any such Insured Event for
costs and expenses incurred by Mortgagor to repair or restore the Property
(collectively the "Repairs") in accordance with, and satisfaction of, the terms
and conditions for disbursement relative to the Replacement Reserve as described
on Exhibit C hereto.

          (b) In the event any proceeds or awards from an Insured Event exceed
the Threshold Amount but less than fifty percent (50%) of the Improvements
located on the Real Estate have been taken or destroyed, then if

               (1) the Property can, in Mortgagee's reasonable judgment, with
     diligent restoration or repair, be returned to a condition at least equal
     to the condition thereof that existed prior to the casualty or partial
     taking causing the loss or damage by the earlier to occur of the following
     dates: (i) six (6) months after the receipt of insurance proceeds or
     condemnation awards by either Mortgagor or Mortgagee, and (ii) six (6)
     months prior to the stated maturity date of the Note, and

               (2) all necessary governmental approvals can be obtained to allow
     the rebuilding and reoccupancy of the Property as described in subsection
     (b)(1) above, and

               (3) there are sufficient sums available (through insurance
     proceeds or condemnation awards and contributions by Mortgagor, the fill,
     amount of which shall at Mortgagee's option have been deposited with
     Mortgagee) for such restoration or repair (including, without limitation,
     for, any reasonable costs and expenses of Mortgagee to incurred in
     administering said restoration or repair) and for payment of principal and
     interest to become due and payable under the Note during such restoration
     or repair, and

               (4) the economic feasibility of the Improvements after such
     restoration or repair will be such that income from their operation is
     reasonably anticipated to be sufficient to pay operating expenses of the
     Property and debt service on the indebtedness secured hereby in full with
     the same coverage ratio considered by Mortgagee in its determination to
     make the Loan, and

               (5) Mortgagor shall have delivered to Mortgagee, at Mortgagor's
     sole cost and expense, an appraisal report from an appraiser, in form and
     substance, satisfactory to Mortgagee appraising the value of the Property
     as proposed to be restored or repaired to be not less than the appraised
     value of the Property considered


                                      -20-

<PAGE>

     by Mortgagee in its determination to make the Loan, then, Mortgagee shall,
     solely for the purposes of such restoration or repair, advance so much of
     the remainder of such sums as may be required to facilitate such
     restoration or repair, and any funds deposited by Mortgagor therefor, to
     Mortgagor in the manner and upon such terms and conditions as would be
     required by a prudent interim construction lender, including, but not
     limited to, the prior approval by Mortgagee of plans and specifications,
     contractors and the form of construction contracts and the furnishing to
     Mortgagee of permits, bonds, lien waivers, invoices, receipts and
     affidavits from contractors and subcontractors in form and substance
     reasonably satisfactory to Mortgagee. Any remaining proceeds shall be
     applied by Mortgagee for payment of the indebtedness secured hereby
     (without prepayment penalty or premium) in whatever order as Mortgagee
     directs, or released to Mortgagor, in its absolute discretion. Mortgagor
     shall, in good faith, undertake reasonable efforts to cause the conditions
     described in this Section 1.9(b) to be fully satisfied (e.g., Mortgagor
     shall timely make applications for necessary governmental permits, shall
     order an appropriate appraisal report, etc.). If such conditions are
     satisfied, Mortgagor shall be obligated to undertake restoration and repair
     of the damaged improvements subject to the terms of this Section 1.9.

     Any disbursement pursuant to this clause (b) of sums by Mortgagee shall,
subject to Mortgagor's satisfaction of the provisions hereof, be in a manner to
promptly facilitate the restoration or repair of the Property. In the event
Mortgagor fails to meet the requirements of this clause (b), then Mortgagee may
elect in its absolute discretion and without regard to the adequacy of
Mortgagee's security, to accelerate the maturity date of the Note and declare
any. and all of the indebtedness secured hereby to be immediately due and
payable and apply the remainder of such sums to the payment of the secured
indebtedness (without prepayment penalty or premium) in whatever order Mortgagee
directs in its sole discretion, with any remainder being paid to Mortgagor.

          (c) In all other cases, namely, in the event That fifty percent (50%)
or more of the Improvements located on the Real Estate have been taken or
destroyed and/or the requirements of Section 1.09(b) are not all satisfied,
Mortgagee may elect, in Mortgagee's absolute discretion and without regard to
the adequacy of Mortgagee's security, to (1) accelerate the maturity date of the
Note and declare any and all indebtedness secured hereby to be immediately due
and payable and apply the remainder of such sums received pursuant to this
Section to the payment of the secured indebtedness in whatever order Mortgagee
directs in its absolute discretion (without prepayment penalty or premium), with
any remainder being paid to Mortgagor, or (ii) make insurance or condemnation
proceeds available to Mortgagor for repair or restoration if Mortgagor
establishes to the satisfaction of Mortgagee, in its sole discretion, that
Mortgagor otherwise satisfies the requirements of Section 1.9(b) above. Should
Mortgagee make the election described immediately above in item (ii) of this
Section 1.9(c), Mortgagor shall be obligated to undertake restoration and repair
of the damaged Improvements consistent with the provisions of this Section 1.9.

          (d) Any reduction in the indebtedness secured hereby resulting from
Mortgagee's application of any sums received by it hereunder shall take effect
only when Mortgagee actually receives such sums and elects to apply such sums to
the indebtedness secured hereby and, in any event, the unpaid portion of the
indebtedness secured hereby shall remain in


                                      -21-

<PAGE>

nearly as possible to its value, condition and character immediately prior to
such casualty or partial taking in accordance with the foregoing provisions and
Mortgagor shall pay to Mortgagee all costs and expenses of Mortgagee incurred in
administering said rebuilding, restoration or repair, provided that Mortgagee
makes such proceeds or award available for such purpose. Mortgagor agrees to
execute and deliver from time to time such further instruments as may be
requested by Mortgagee to confirm the foregoing assignment to Mortgagee of any
award, damage, insurance proceeds, payment or other compensation. Mortgagor
hereby irrevocably constitutes and appoints Mortgagee the attorney in- fact of

interest, shall survive the voluntary or involuntary dissolution of Mortgagor
and shall not be affected by any disability or incapacity suffered by Mortgagor
subsequent to the date hereof), with full power of substitution, subject to the
terms of this Section, to settle for, collect and receive any such awards,

therein would be in any danger of sale, loss or forfeiture as a result of such
proceeding or contest. In the event Mortgagor shall contest any such claim or
demand, Mortgagor shall promptly notify Mortgagee of such contest and thereafter

the occurrence of a default under this Mortgage which has not been cured within:
any applicable grace or cure period, Mortgagee shall be entitled to exercise any

     prior written approval of the Mortgagee, which approval shall not be
     unreasonably withheld. The request for approval of each such proposed
     Mortgage, failure to approve or disapprove such proposed lease within ten
     (10) business days is deemed approval and Mortgagor shall furnish to

     such proposed lease within ten (10) business days after receipt of such
     written request and all the documents and information required to be
     furnished to Mortgagee with such request shall be deemed approval, provided

manner which is consistent with sound and customary leasing and management
practices for similar properties in the community in which the Property is
located. Mortgagor shall not permit the prepayment of any rents under any of the
leases for more than one (1) month prior to the due date thereof.

     1.13. Alienation and Further Encumbrances.

principals of Mortgagor and their experience in owning and operating properties
similar to the Property in connection with the closing of - the Loan.

date of such acceleration. For the purposes of this Section, the sale,
conveyance, transfer, disposition, alienation, hypothecation, pledge or
encumbering (whether voluntarily or involuntarily) of all or any portion of the
ownership interest in (or, directly or indirectly through constituent parties,

     satisfactory to Mortgagee and shall be binding upon the Buyer;

          (8) Subject to the provisions of Section 4.23 hereof, such Sale is not

     agreement must provide for the continued existence of the Buyer in the
     event of the bankruptcy or dissolution of the sole member. The Buyer, if

     existence of the Buyer shall continue until the cancellation of the

     proposed transfer will not result in a re-qualification, reduction,
     downgrade or withdrawal of any rating initially assigned or to be assigned
     in a Secondary Market Transaction (as hereinafter defined) or, if no such
     rating has been issued, in Mortgagee's good faith judgment, such transfer
     shall not have an, adverse effect on the level of rating obtainable in

any kind (including, but not limited to, any bankruptcy, insolvency,
arrangement, reorganization or other debtor relief proceeding) is commenced
which might affect Mortgagee's interest in the Property or Mortgagee's right to
enforce its security, then Mortgagee may, at its option, with or without notice
to Mortgagor, make any appearances, disburse or advance any sums and take any
actions as may be necessary or desirable to protect or enforce the security of
this Mortgage or to remedy the failure of Mortgagor to perform its covenants and

for the purpose of performing or observing any such defaulted term, covenant or
condition without thereby becoming liable to Mortgagor or any person in
possession holding under Mortgagor. Mortgagor hereby acknowledges and agrees

Mortgagee, and any and all payments made or costs or expenses incurred by
Mortgagee in connection therewith shall be secured hereby and shall be, without
demand, immediately repaid by Mortgagor with interest thereon at the Default
Interest Rate (as defined in the Note), notwithstanding the fact that such
remedies were exercised and such payments made and costs incurred by Mortgagee
after the filing by Mortgagor of a voluntary case or the filing against
Mortgagor of an involuntary case pursuant to or within the meaning of the
Bankruptcy Reform Act of 1978, as amended (the "Act"), Title 11 U.S.C., or after
any similar action pursuant to any other debtor relief law (whether statutory,
common law, case law or otherwise) of any jurisdiction whatsoever, now or
hereafter in effect, which may be or become applicable to Mortgagor, Mortgagee,
any guarantor or indemnitor, the secured indebtedness or any of the Loan
Documents, This indemnity shall survive payment in full of the indebtedness
secured hereby. This Section 1.20(b) shall not be construed to require Mortgagee
to incur any expenses, make any appearances or take any actions.

create a security interest in, and Mortgagor hereby grants to Mortgagee a
security interest in, all Reserves (as hereinabove defined), fixtures, chattels,
accounts, equipment, inventory, contract rights, general intangibles and other
personal property included within the Property, all renewals, replacements of
any of the aforementioned items, or articles in substitution therefor or in
addition thereto or the proceeds thereof (said property is hereinafter referred
to collectively as the "Collateral"), whether or not the same shall be attached
to the Real Estate or the Improvements in any manner. It is hereby agreed that
to the extent permitted by law, all of the foregoing property is to be deemed
and held to be a part of and affixed to the Real Estate and the Improvements.
The foregoing security interest shall also cover Mortgagor's leasehold interest
in any of the foregoing property which is leased by Mortgagor. Notwithstanding

leasing or installment sales or other financing or title retention agreement in
connection therewith shall be permitted without the prior written approval of
Mortgagee. Mortgagor shall promptly replace all of the Collateral subject to the
lien or security interest of this Mortgage when worn out or obsolete with
Collateral comparable to the worn out or obsolete Collateral when new and will

interest of this Mortgage except such as is replaced by an article of equal
suitability and value as above provided, owned by Mortgagor free and clear of
any lien or security interest except that created by this Mortgage and the other
Loan Documents and except as otherwise expressly permitted by the terms of
Section 1.13 of this Mortgage. All of the Collateral shall be kept at the
location of the Real Estate except as otherwise required by the terms of the

Collateral in which Mortgagee is granted a security interest hereunder, and,

Mortgagee until actually paid by Mortgagor, shall be paid by Mortgagor on demand
and shall be secured by this Mortgage and by all of the other Loan Documents

required by law, Mortgagee shall give Mortgagor at least ten (10) days prior
written notice of the time and place of any public sale of such property or of
the time of or after which any private sale or any other intended disposition
thereof is to be made, and if such notice is sent to Mortgagor, as the same is
provided for the mailing of notices herein, it is hereby deemed that such notice
shall be and is reasonable notice to Mortgagor. No such notice is necessary for
any such property which is perishable, threatens to decline speedily in value or
is of a type customarily sold on a recognized market. Any sale made pursuant to
the provisions of this Section 1.22 shall be deemed to have been a public sale
conducted in a commercially reasonable manner if held contemporaneously with the

notice with respect to the sale of the property hereunder as is required under
said Section 3.1(e). Furthermore, to the extent permitted by law, in conjunction

option of Mortgagee, be sold as a whole; and

               It shall not be necessary that Mortgagee take possession of the
aforementioned Collateral, or any part thereof, prior to the time that any safe
pursuant to the provisions of this Section 1.22 is conducted and it shall not be
necessary that said Collateral, or any part thereof, be present at the location
of such sale; and

          (c) Mortgagee may appoint or delegate any one or more persons as agent
to perform any act or acts necessary or incident to any sale held by Mortgagee,
including the sending of notices and the conduct of the sale, but in the name
and on behalf of Mortgagee.

executive office set forth below, or change the state of its organization or
registration, or change its name, without in each instance the prior written
consent of Mortgagee, which consent shall not be unreasonably withheld, delayed
or conditioned. Mortgagee's consent will, however, be conditioned upon, among
other things, the execution and delivery(,) of additional- financing statements,
security agreements and other instruments which may be necessary to effectively

provision of this Mortgage or as an election of remedies to the exclusion of any
other remedy which may then or thereafter be available to Mortgagee. No delay or
failure by Mortgagee to exercise any right or remedy under this Mortgage shall
be construed to be a waiver of that right or remedy or of any default hereunder.

without regard to the adequacy of its security.

default, and may remedy any default by Mortgagor hereunder without waiving the
default remedied. Neither the failure or delay by Mortgagee in exercising, any
right, power or remedy upon any default by Mortgagor hereunder shall be

by Mortgagee of any right, power or remedy hereunder shall exhaust the same or
shall preclude any other or


                                      -60-

<PAGE>

Further exercise thereof, and every such right, power or remedy hereunder may be

Mortgagor in any case shall of itself entitle Mortgagor to any other or further
notice or demand in similar or other circumstances. Acceptance by Mortgagee of

way affect the existence of a default hereunder.

Mortgage are for convenience of reference only, are not to be considered a part
hereof and shall not limit or otherwise affect any of the terms hereof.

contract, or any one or more of the foregoing, in order to fully effectuate the
liens and security interests created hereby and the purposes and agreements

secured hereby and to increase the amount of the indebtedness secured hereby and
to waive or forebear the exercise of any of its rights and remedies hereunder or
under any of the other Loan Documents and to release any collateral or security

Mortgage.

observed, performed or fulfilled or to be given to Mortgagee pursuant to the
Loan Documents, including, but not limited to, any officer's certificate,

survey, appraisal or insurance policy, Mortgagee shall not be deemed to have
warranted, consented to, or affirmed the sufficiency, legality, effectiveness or
legal effect of the same, or of any term, provision or condition thereof, and
such acceptance of delivery thereof shall not be or constitute any warranty,
consent or affirmation with respect thereto by Mortgagee.


                                      -62-

     4.22. Counterparts. This Mortgage may be executed in any number of
counterparts, each of which shall be effective only upon delivery and thereafter
shall be deemed an original, and all of which shall be taken to be one and the
same instrument, for the same effect as if all parties hereto had signed the
same signature page.

     4.23. Personal Liability. Notwithstanding anything to the contrary
contained in this Mortgage, the liability of Mortgagor and its general partners
for the indebtedness secured hereby and for the performance of the other
agreements, covenants and obligations contained herein and in the Loan Documents
shall be limited as set forth in Section 1.05 of the Note; provided, however,
that nothing herein shall be deemed to be a waiver of any right which Mortgagee
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 indebtedness
secured hereby or to require that all collateral shall continue to secure all
indebtedness owing to Mortgagee in accordance with the Note, this Mortgage and
the other Loan Documents,

     4.24. Recording and Filing. Mortgagor will cause the Loan Documents and all
amendments and supplements thereto and substitutions therefor to be recorded,
filed, re-recorded and re-filed in such manner and in such places as Mortgagee
shall reasonably request, and will pay on demand all such recording, filing,
re-recording and re-filing taxes, fees and other charges. Mortgagor shall
reimburse Mortgagee, or its servicing agent, for the costs incurred in obtaining
a tax service company to verify the status of payment of taxes and assessments
on the Property.

     4.25. Entire Agreement and Modifications,. This Mortgage and the other Loan
Documents contain the entire agreements between the parties and supersede any
prior agreements (oral or written), and may not be amended, revised, waived,
discharged, released or terminated orally but only by a written instrument or
instruments executed by the party against which enforcement of the amendment,
revision, waiver, discharge, release or termination is asserted.

     4.26. Maximum Interest. The provisions of this Mortgage and of all
agreements between Mortgagor and Mortgagee, whether now existing or hereafter
arising and whether written or oral, are hereby expressly limited so that in no
contingency or event whatsoever, whether by reason of demand or acceleration of
the maturity of the Note or otherwise, shall the amount paid; or agreed to be
paid ("Interest"), to Mortgagee for the use, forbearance or retention of the
money loaned under the Note exceed the maximum amount permissible under
applicable law. If, from any circumstance whatsoever, performance or fulfillment
of any provision hereof or of any agreement between Mortgagor and Mortgagee
shall, at the time performance or fulfillment of such provision shall be due,
exceed the limit for Interest prescribed by law or otherwise transcend the limit
of validity prescribed by applicable law, then ipso facto the obligation to be
performed or fulfilled shall be reduced to such limit and if, from any
circumstance whatsoever, Mortgagee shall ever receive anything of value deemed
Interest by applicable law in excess of the maximum lawful amount, an amount
equal to any excessive Interest shall be applied to the reduction of the
principal balance owing under the Note in the inverse order of its maturity
(whether or not then due) or at the option of Mortgagee be paid over to
Mortgagor, and not to the payment of Interest. All Interest (including any
amounts or payments judicially or otherwise under law deemed to be Interest)
contracted for, charged, taken, reserved, paid or agreed to be paid to Mortgagee
shall, to the extent permitted by applicable law,


                                      -63-

<PAGE>

be, amortized, prorated, allocated and spread throughout the full term of the
Note, including any extensions and renewal thereof, until payment in full of the
principal balance of the Note so that the Interest thereon for such full term
will not at any time exceed the maximum amount permitted by applicable law. This
Section 4.26 will control all agreements between Mortgagor and Mortgagee.

     4.27. Application of Default Interest Rate Not a Waiver. Application of the
Default Interest Rate shall not be deemed to constitute a waiver of any default
or any rights or remedies of Mortgagee under this Mortgage, any other Loan
Document or applicable legal requirements, or a consent to any extension of time
for the payment or performance of any obligation with respect to which the
Default Interest Rate may be invoked.

     4.28. Interest Payable by Mortgagee. Mortgagee shall cause funds in the
Replacement Reserve and TIC Reserve (the "Funds") to be deposited into interest
bearing accounts of the type customarily maintained by Mortgagee or its
servicing agent for the investment of similar reserves, which accounts may not
yield the highest interest rate then available. The Funds shall be held in an
account in Mortgagee's name (or such other account name as Mortgagee may elect)
at a financial institution or other depository selected by Mortgagee (or its
servicer) in its sole discretion (collectively, the "Depository Institution").
Mortgagor shall earn no more than an amount of interest on the Funds equal to an
amount determined by applying to the average monthly balance of such Funds the
quoted interest rate for the Depository Institution's money market savings
account, as such rate is determined from time to time (such allocated amount
being referred to as "Mortgagor's Interest"). Mortgagee or its Depository
Institution shall be entitled to report under Mortgagor's Federal tax
identification number, Mortgagor's Interest on the Funds. If the Depository
Institution does not have an established money market savings account (or if an
interest rate for such account cannot otherwise be determined in connection with
the deposit of such Funds), a comparable interest rate quoted by the Depository
Institution and acceptable to Mortgagee (or its servicer) in its reasonable
discretion shall be used. The amount of Mortgagor's Interest allocated to Funds
shall be added to the balance in the applicable Reserve, and shall be disbursed
for payment of the items for which other Funds in the applicable Reserve axe to
be disbursed.

     4.29. Further Stipulations. The additional covenants, agreements and
provisions set forth in Exhibit. C attached hereto, if any, shall be a part of
this Mortgage and shall, in the event of any conflict between such further
stipulations and any of the other provisions of this Mortgage, be deemed to
control.

     4.30. Relationship of the Parties. The relationship between Mortgagor and
Mortgagee is that of a borrower and a lender only and neither of those parties
is, nor shall it hold itself out to be, the agent, employee, joint venturer or
partner of the other party.

     4.31. Fixture Filing. This Mortgage shall be effective from the date of its
recording as a financing statement filed as a fixture filing with respect to all
goods constituting part of the Property which are or are to become fixtures. The
mailing address of Mortgagor and the address of Mortgagee from which information
concerning the security interests may be obtained are set forth in Section 1.22
above.


                                      -64-

     4.32. Cooperation With Rating Agencies and Investors. Mortgagor covenants
and agrees that in the event Mortgagee decides to include the Loan as an asset
of a Secondary Market Transaction (as defined herein), Mortgagor shall (a) at
Mortgagee's request, meet with representatives of the Rating Agencies and/or
investors to discuss the business and operations of the Property, and (b) permit
Mortgagee or its representatives to provide related information to the Rating
Agencies and/or investors, and (c) cooperate with the reasonable requests of the
Rating Agencies and/or investors in connection with all of the foregoing. For
purposes hereof, a "Secondary Market Transaction" shall be (a) any sale or
assignment of this Mortgage, Note and other Loan Documents to one or more
investors as a whole loan; (b) a participation of the Loan to one or more
investors, (c) any deposit of this Mortgage, the Note and the other Loan
Documents with a trust or other entity which may sell certificates or other
instruments to investors evidencing an ownership interest in the assets of such
trust or other entity, or (d) any other sale, assignment or transfer of the Loan
or any interest therein to one or more investors. If at any time during which
the Loan is an asset of a securitization or is otherwise an asset of any rated
transaction, "Rating Agency" shall mean the rating agency or rating agencies
that from time to time rate the securities, certificates or other instruments
issued in connection with such securitization or other transaction.

     4.33. Pennsylvania Provisions. Pursuant to 42 Pa. C.S.A. Section 8144, this
Mortgage secures the unpaid balance of advances made, with respect to the
Property, for the payment of taxes, assessments, maintenance charges, insurance
premiums or costs incurred by Mortgagee for the protection of the Property or
the lien of this Mortgage, and expenses incurred by Mortgagee by reason of an
Event of Default, and the priority of the lien of such advances shall relate
back to the date of the recording of this Mortgage.

     C-1 Repair and Remediation Reserve. Prior to the execution of this
Mortgage, Mortgagee has caused the Property to be inspected and such inspection

remedial or corrective work. Contemporaneously with the execution hereof,
Mortgagor has established with the Mortgagee a reserve in the amount of
$6,875.00 (the "Repair and Remediation Reserve"), which amount represents 125%
of the estimated cost to complete such items of Deferred Maintenance (as defined
herein), by depositing such amount with Mortgagee. Mortgagor shall cause each of
the items described in that certain engineering report dated April 24, 2003 and
prepared by ComTech Services, Inc. ComTech Services, Inc. as reviewed and
commented on by a desktop review prepared by Certified Environments, Inc. dated
April 29, 2003 (all of the foregoing, the "Engineering Report"), relative to the
Property, a copy of which has been provided to, and receipt of which is hereby
acknowledged by, Mortgagor (the "Deferred Maintenance") to be completed,
performed, remediated and corrected to the satisfaction of Mortgagee and as
necessary to bring the Property into compliance with all applicable laws,
ordinances, rules and regulations on or before one year from the date hereof, as
such time period may be extended by Mortgagee in its sole discretion. So long as
no default hereunder or under the other Loan Documents has occurred and is
continuing (i) all sums in the Repair and Remediation Reserve shall be held by
Mortgagee in the Repair and Remediation Reserve to pay the costs and expenses of
completing the Deferred Maintenance, and (ii) Mortgagee shall, to the extent
funds are available for such purpose in the Repair and Remediation Reserve,
disburse to Mortgagor the amount paid or incurred by Mortgagor in completing,
performing, remediating or correcting the Deferred Maintenance upon (a) the
receipt by Mortgagee of a written request from Mortgagor for disbursement from
the Repair' and Remediation Reserve which shall include a certification by
Mortgagor that the applicable item of Deferred Maintenance has been completed in
accordance with the terms of this Mortgage, (b) delivery to Mortgagee of
invoices, receipts or other evidence satisfactory to Mortgagee verifying the

or other consultant reasonably acceptable to Mortgagee describing the completed
work, verifying the completion of the work and the value of the completed work
and, if applicable, certifying that the Property is, as a result of such work,
in compliance with all applicable laws, ordinances, rules and regulations
relating to the Deferred Maintenance so performed, and (d) delivery to Mortgagee

     THAT, WHEREAS, Borrower has executed a certain Promissory Note dated of
even date herewith (the "Note"), payable to the order of Lender in the stated
principal amount of TEN MILLION FIVE HUNDRED THOUSAND AND NO/100 DOLLARS
($10,500,000.00) (the "Loan"); and

     WHEREAS, the Note is secured by, among other things, that certain Mortgage
and Security Agreement dated of even date herewith (the "Security Instrument"),
from Borrower, as mortgagor, encumbering that certain real property situated in
the County of Philadelphia, Commonwealth of' Pennsylvania, as is more
particularly described on Exhibit A attached hereto and incorporated herein by
this reference, and together with all buildings and other improvements now or
hereafter located thereon (collectively, the 'Improvements) (said real property
and the Improvements are hereinafter sometimes collectively referred to as the
'Property'); and

     WHEREAS, Borrower is desirous of further securing to Lender the performance
of the terms, covenants and agreements hereof and of the Note, the Security
Instrument and each other document and agreement evidencing, securing,
guaranteeing or otherwise relating to the indebtedness evidenced by the Note
(the Note, the Security Instrument and such other documents and agreements, as
each of the foregoing may from time to time be amended, consolidated, renewed or

     NOW, THEREFORE, in consideration of the making of the Loan evidenced by the
Note by Lender to Borrower and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, Borrower does hereby
irrevocably, absolutely and unconditionally transfer, sell, assign, pledge and
convey to Lender, its successors and assigns, all of the right, title and
interest of Borrower in and to:

     (a) any and all leases, licenses, rental agreements and occupancy

collect and receive the same, whether now due or hereafter becoming due, and
together with all rights and claims of any kind that Borrower may have against
any tenant, lessee or licensee under the Leases or against any other occupant of
the Property (collectively, the "Rents").

     TO HAVE AND TO HOLD the same unto Lender, its successors and assigns.

     IT IS AGREED that, notwithstanding that this instrument is a present,
absolute and executed assignment of the Rents and of the Leases arid a present,
absolute and executed grant of the powers herein granted to Lender, Borrower is
hereby permitted, at the sufferance of Lender and at its discretion, and is
hereby granted a license by Lender, to retain possession of the Leases and to
collect and retain the Rents unless and until there shall be a default under the
terms of any of the Loan Documents, which default has not been cured within any
applicable grace or cure period. In the event of such uncured default, the
aforementioned license granted to Borrower shall automatically terminate without
notice to Borrower, and Lender may thereafter, without taking possession of the
Property, demand, collect (by suit or otherwise), receive and give valid and
sufficient receipts for any and all of the Rents or take possession of the
Leases, for which purpose Borrower does hereby irrevocably make, constitute and
appoint Lender its attorney in fact with full power to appoint substitutes or a
trustee to accomplish such purpose (which power of attorney shall be irrevocable
so long as any portion of the Loan is outstanding shall be deemed to be coupled
with an interest, shall survive the voluntary or involuntary dissolution of
Borrower and shall not be affected by any disability or incapacity suffered by
Borrower subsequent to the date hereof). Further, from and after such
termination, Borrower shall be the agent of Lender in collection of the Rents,
and any Rents so collected by Borrower shall be held in trust by Borrower for
the sole and exclusive benefit of Lender and Borrower shall, within one (I)
business thy after receipt of any Rents, pay the same to Lender to be applied by
Lender as hereinafter set forth. Further, from and after such uncured default
and termination of the aforementioned license, Lender shall have the right and
authority, without any notice whatsoever to Borrower and without regard to the
adequacy of the security therefore, to: (a) manage and operate the Property,
with full power to employ agents to manage the same; (b) demand, collect,
receive and sue for the Rents, including those past due and unpaid; and (c) do
all acts relating to such management of the Property, including, but not limited
to, negotiation of new Leases, making adjustments of existing Leases,
contracting and paying for repairs and replacements to the Improvements and to
the fixtures, equipment and personal property located in the Improvements or
used in any way in the operation, use and occupancy of the Property as in the
sole subjective judgment and discretion of Lender may be necessary to maintain
the same in a tenantable condition, purchasing and paying for such additional
furniture arid equipment as in the sole subjective judgment of Lender may be
necessary to maintain a proper rental income from the Property, employing
necessary managers and other employees, purchasing fuel, providing utilities and
paying for all other expenses incurred in the operation of the Property,
maintaining adequate insurance coverage over hazards customarily insured against
and paying the premiums therefore. Lender may apply the Rents received by Lender
from the Property, after deducting the

<PAGE>

costs of collection thereof, including, without limitation, attorneys' fees and
a management fee for any management agent so employed, against amounts expended
for repairs, upkeep, maintenance, service, fuel, utilities, taxes, assessments,
insurance premiums and such other expenses as Lender incurs in connection with
the operation of the Property and against interest, principal, required escrow
deposits and other sums which have or which may become due, from time to time,
under the terms of the Loan Documents, in such order or priority as to any of
the items so mentioned as Lender, in its sole subjective discretion, may
determine. The exercise by Lender of the rights granted Lender in this
paragraph, and the collection of the Rents and the application thereof as herein
provided, shall not be considered a waiver by Lender of any default under the
Loan Documents or prevent foreclosure of any liens on the Property nor shall
such exercise make Lender liable under any of the Leases, Lender hereby
expressly reserving all of its rights and privileges under the Security
Instrument and the other Loan Documents as fully as though this Assignment had
not been entered into.

     Without limiting the rights granted hereinabove, in the event Borrower
shall fall to make any payment or to perform any act required under the terms
hereof and such failure shall not be cured within any applicable grace or cure
period, then Lender may, but shall not be obligated to, without prior notice to
or demand on Borrower, and without releasing Borrower from any obligation
hereof, make or perform the same in such manner and to such extent as Lender may
deem necessary to protect the security hereof, including specifically, without
limitation, appearing in and defending any action or proceeding purporting to
affect the security hereof or the rights or powers of Lender, performing or
discharging any obligation, covenant or agreement of Borrower under any of the
Leases, and, in exercising any of such powers, paying all necessary costs and
expenses, employing counsel and incurring and paying attorneys' fees. Any sum
advanced or paid by Lender for any such purpose, including, without limitation,
attorneys' fees, together with interest thereon at the Default Interest Rate (as
defined in the Note) from the date paid or advanced by Lender until repaid by
Borrower, shall immediately be due and payable to Lender by Borrower on demand
and shall be secured by the Security Instrument and by all of the other Loan
Documents securing all or any part of the indebtedness evidenced by the Note.

     IT IS FURTHER AGREED that this Assignment is made upon the following terms,
covenants and conditions:

     I. This Assignment shall not operate to place responsibility for the
control, care, management or repair of the Property upon Lender, nor for the
performance of any of the terms and conditions of any of the Leases, nor shall
it operate to make Lender responsible or liable for any waste committed on the
Property by the tenants or any other party or for any dangerous or defective
condition of the Property or for any negligence in the management, upkeep,
repair or control of the Property. Lender shall not be liable for any loss
sustained by Borrower resulting from Lender's failure or inability to collect
Rents, proceeds or other payments, or to let the Property, or from any other act
or omission of Lender in managing the Property. BORROWER SHALL AND DOES HEREBY
INDEMNIFY AND HOLD LENDER HARMLESS FROM AND AGAINST ANY AND ALL LIABILITY, LOSS,
CLAIM, DEMAND OR DAMAGE WHICH MAY OR MIGHT BE INCURRED BY REASON OF THIS
ASSIGNMENT, INCLUDING, WITHOUT LIMITATION, CLAIMS OR DEMANDS FOR SECURITY

LIABILITY BY REASON OF THIS ASSIGNMENT OR IN DEFENSE OF ANY CLAIM OR DEMAND FOR
LOSS OR DAMAGE AS PROVIDED ABOVE, THE AMOUNT THEREOF, INCLUDING, WITHOUT
LIMITATION, COSTS, EXPENSES AND ATTORNEYS' FEES, TOGETHER WITH INTEREST THEREOF
AT THE DEFAULT INTEREST RATE FROM THE DATE PAID OR INCURRED BY LENDER UNTIL

UPON DEMAND AND SHALL BE SECURED BY THE SECURITY INSTRUMENT AND BY ALL OF THE
OTHER LOAN DOCUMENTS SECURING ALL OR ANY PART OF THE INDEBTEDNESS EVIDENCED BY
THE NOTE.

possession.

     3. Lender is obligated to account to Borrower only for such Rents as are
actually collected or received by Lender.

     4. Borrower hereby further presently and absolutely assigns to Lender
subject to the terms and provisions of this Assignment: (a) any award or other
payment which Borrower may hereafter become entitled to receive with respect to
any of the Leases as a result of or pursuant to any bankruptcy, insolvency or
reorganization or similar proceedings involving the tenants under such Leases;
and (b) any and all payments made by or on behalf of any tenant of any part of
the Property in lieu of Rent. Borrower hereby irrevocably appoints Lender as its
attorney- in fact to, from and after the occurrence of a default by Borrower
hereunder or under any of the other Loan Documents which has not been cured
within any applicable grace or cure period, appear in any such proceeding and to
collect any such award or payment, which power of attorney is coupled with an
interest by virtue of this Assignment and is irrevocable so long as any sums are
outstanding under the loan evidenced by the Note.

     5. Borrower represents, warrants and covenants to and for the benefit of
Lender: (a) that Borrower now is (or with respect to any Leases not yet in
existence, will be immediately upon the execution thereof) the absolute owner of
the landlord's interest in the Leases, with full right and title to assign the
same and the Rents due or to become due thereunder; (b) that, other than this
Assignment and those assignments if any, specifically permitted in the Security
Instrument, there are no outstanding pledges or assignments of the Leases or
Rents; (c) that no Rents have been anticipated, discounted, released, waived,
compromised or otherwise discharged except for prepayment of rent of not more
than one (1) month prior to the accrual thereof; (d) that there are no material
defaults now existing under any of the Leases by the landlord or tenant; and, to
the best of Borrowers knowledge, there exists no state of facts which, with the
giving of notice or lapse of time or both, would constitute a default under any
of the Leases by the landlord or tenant; except as disclosed in writing to
Lender; (e) that Borrower has and shall duly and punctually observe and perform
all covenants, conditions and agreements in the Leases on the part of the
landlord to be observed and performed thereunder; and (f) the Leases are in full
force

knowledge of Borrower, are the valid and binding obligations of the tenants
thereto.

written consent of Lender: (a) exclusive of security deposits, accept any
payment of Rent or installments of Rent for more than one (I) month in advance;
(b) enter into any Lease having a term of less than six (6) months or in excess

other than the lien of the Security Instrument provided, however, that Borrower
may take any of the actions described in subsection (c) or (e) above so long as
such actions are taken by Borrower in tie ordinary course of business and are
consistent with sound customary leasing and management practices for similar
properties.

     7. Borrower covenants and agrees that Borrower shall, at its sole cost and
expense, appear in and defend any action or proceeding arising under, growing
out of, or in any manner connected with the Leases or the obligations, duties or
liabilities of the landlord or tenant thereunder, and shall pay on demand all
costs and expenses, including, without limitation, attorneys' fees, which Lender
may incur in connection with Lender's appearance, voluntary or otherwise, in any
such action or proceeding, together with interest thereon at the Default
Interest Rate from the date incurred by Lender until repaid by Borrower.

     8. At any time, Lender may, at its option, notify any tenants or other
parties of the existence of this Assignment. Borrower does hereby specifically
authorize, instruct and direct each and every present and future tenant, lessee
and licensee of the whole or any part of the Property to pay all unpaid and
future Rents to Lender upon receipt of demand from Lender to so pay the sane and
Borrower hereby agrees that each such present and future tenant, lessee and
licensee may rely upon such written demand from Lender to so pay said Rents
without any inquiry into whether there exists a default hereunder or under the
other Loan Documents or whether Lender is otherwise entitled to said Rents,
Borrower hereby waives any right, claim or demand which Borrower may now or
hereafter have against any present or future tenant lessee or licensee by reason
of such payment of Rents to Lender, and any such payment shall discharge such
tenant's, lessee's or licensee's obligation to make such payment to Borrower.

     9. Lender may take or release any security for the indebtedness evidenced
by the Note, may release any party primarily or secondarily liable for the
indebtedness evidenced by the Note, may grant extensions, renewals or
indulgences with respect to the indebtedness evidenced by the Note and may apply

evidenced by the Note without prejudice to any of its rights hereunder.

<PAGE>

     10. The acceptance of this Assignment and the collection of the Rents in
the event Borrower's license is terminated, as referred to above, shall be
without prejudice to Lender. The rights of Lender hereunder are cumulative and
concurrent, may be pursued separately, successively or together and may be
exercised as often as occasion therefore shall arise, it being agreed by
Borrower that the exercise of any one or more of the rights provided for herein
shall not be construed as a waiver of any of the other rights or remedies of
Lender, at law or in equity or otherwise, so long as any obligation under the
Loan Documents remains unsatisfied.

     11. All rights of Lender hereunder shall inure to the benefit of its
successors and assigns, and all obligations of Borrower shall bind its
successors and assigns and any subsequent owner of the Property. All rights of
Lender in, to and under this Assignment shall pass to and may be exercised by
any assignee of such rights of Lender. Borrower hereby agrees that if Lender
gives notice to Borrower of an assignment of said rights, upon such notice the
liability of Borrower to the assignee of the Lender shall be immediate and
absolute. Borrower will not set up any claim against Lender or any intervening
assignee as a defense, counterclaim or set-off to any action brought by Lender
or any intervening assignee for any amounts due hereunder or for possession of
or the exercise of rights with respect to the Leases or the Rents.

     12. It shall be a default hereunder (a) if any representation or warranty
made herein by Borrower is determined by Lender to have been false or misleading
in any material respect at the time made, or (b) upon any failure by Borrower to
comply with the provisions of Paragraph 6 above or (c) upon any failure by
Borrower in the performance or observance of any other covenant or condition
hereof and, to the extent such failure described in this subsection (c) is
susceptible of being cured, the continuance of such failure for thirty (30) days
after written notice thereof from Lender to Borrower; provided, however, that if
such default is susceptible of cure but such cure cannot be accomplished with
reasonable diligence within said period of time, and if Borrower commences to
cure such default promptly after receipt of notice thereof from Lender, and
thereafter prosecutes the curing of such default with reasonable diligence, such
period of time shall be extended for such period of time as may be necessary to
cure such default with reasonable diligence, but not to exceed an additional
ninety (90) days. Any such default not so cured shall be a default under each of
the other Loan Documents, entitling Lender to exercise any or all rights and
remedies available to Lender under the terms hereof or of any or all of the
other Loan Documents, and any default under any other Loan Document which is not
cured within any applicable grace or cure period shall be deemed a default
hereunder subject to no grace or cure period, entitling Lender to exercise any
or all rights provided for herein, -

     13. Failure by Lender to exercise any right which it may have hereunder
shall not be deemed a waiver thereof unless so agreed in writing by Lender, and
the waiver by Lender of any default hereunder shall not constitute a continuing
waiver or a waiver of any other default or of the same default on any future
occasion, No collection by Lender of any Rents pursuant to this Assignment shall
constitute or result in a waiver of any default then existing hereunder or under
any of the other Loan Documents.

     14. If any provision under this Assignment or the application thereof to
any entity, person or circumstance shall be invalid, illegal or unenforceable to
any extent, the remainder of this Assignment and the application of the
provisions hereof to other entities, persons or

<PAGE>

circumstances shall not be affected thereby and shall be enforced to the fullest
extent permitted by law.

     15. This Assignment may not be amended, modified or otherwise changed
except by a written instrument duly executed by Borrower and Lender.

     16. This Assignment shall be in full force and effect continuously front
the date hereof to and until the Security Instrument shall be released of
record, and the release of the Security Instrument shall, for all purposes,
automatically terminate this Assignment and render this Assignment null and void
and of no effect whatsoever.

     17. All notices, demands, requests or other communications to be sent by
one party to the other hereunder or required by law shall be given and become
effective as provided in the Security Instrument.

     18. THIS ASSIGNMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE COMMONWEALTH OP PENNSYLVANIA, EXCEPT TO THE EXTENT THAT ANY OF
SUCH LAWS MAY NOW OR HEREAFTER BE PREEMPTED BY FEDERAL LAW, IN WHICH CASE SUCH
FEDERAL LAW SHALL SO GOVERN AND BE CONTROLLING; PROVIDED HOWEVER THAT THE LAWS
OF THE STATE IN WHICH THE REAL PROPERTY ON EXHIBIT A ATTACHED HERETO IS LOCATED
SHALL GOVERN AS TO THE CREATION, PRIORITY AND ENFORCEMENT OF LIENS AND SECURITY
INTERESTS IN PROPERTY LOCATED IN SUCH STATE.

     19. This Assignment may be executed in any number of counterparts, each of
which shall be effective only upon delivery and thereafter shall be deemed an
original, and all of which shall be taken to be one and the same instrument, for
the same effect as if all parties hereto had signed the same signature page. Any
signature page of this Assignment may be detached front any counterpart of this
Assignment without impairing the legal effect of any signatures thereon and may
be attached to another counterpart of this Assignment identical in form hereto
but having attached to it one or more additional signature pages.

     20. In addition to, but not in lieu of, any other rights hereunder, Lender
shall have the right to institute suit and obtain a protective or mandatory
injunction against Borrower to prevent a breach or default, or to enforce the
observance, of the agreements, covenants, terms and conditions contained herein,
as well as the right to damages occasioned by any breach or default This
Assignment shall continue and remain in full force and effect during any period
of foreclosure with respect to the Property.

     21. Borrower hereby covenants and agrees that Lender shall be entitled to
all of the rights, remedies and benefits available by statute, at law, in equity
or as a matter of practice for the enforcement and perfection of the intents and
purposes hereof. Lender shall, as a matter of absolute right, be entitled, upon
application to a court of applicable jurisdiction, to the appointment of a
receiver to obtain and secure the rights of Lender hereunder and the benefits
intended to be provided to Lender hereunder.

     22. Notwithstanding anything to the contrary contained in this Assignment,
the liability of Borrower and its general partners for the indebtedness secured
hereby and for the

<PAGE>

performance of the other agreements, covenants and obligations contained herein
and in the Loan Documents shall be limited as set forth in Section 1.05 of the

any right which Assignee 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 indebtedness secured hereby or to require that all collateral shall
continue to secure all indebtedness owing to Lender in accordance with the Note,
this Assignment and the other Loan Documents.
