     This Loan And Security Agreement (as amended, modified or supplemented from
time to time, this "Agreement") is entered into as of December 20, 2002, by and
between Comerica Bank-California ("Bank") and Align Technology, Inc., a Delaware
corporation ("Borrower").

                                    RECITALS

     Borrower wishes to obtain credit from time to time from Bank, and Bank
desires to extend credit to Borrower. This Agreement sets forth the terms on
which Bank will advance credit to Borrower, and Borrower will repay the amounts
owing to Bank.

                                    AGREEMENT

     The parties agree as follows:

     1.   Definitions And Construction.

          1.1 Definitions. As used in this Agreement, the following terms shall
have the definitions set forth on Exhibit A.

          1.2 Accounting Terms. All accounting terms not specifically defined on
Exhibit A shall be construed in accordance with GAAP and all calculations shall
be made in accordance with GAAP. The term "financial statements" shall include
the accompanying notes and schedules.

     2.   Loans And Terms Of Payment.

          2.1 Credit Extensions. Borrower promises to pay to Bank, in lawful
money of the United States of America, the aggregate unpaid principal amount of
all Credit Extensions made by Bank to Borrower, together with interest on the
unpaid principal amount of such Credit Extensions at rates in accordance with
the terms hereof.

               (a)  Revolving Advances.

                    (i) Subject to and upon the terms and conditions of this
Agreement, Bank, agrees to make advances (each a "Revolving Advance" and
collectively, the "Revolving Advances") to Borrower, subject to Section
2.1(a)(ii), in an aggregate outstanding amount not to exceed the lesser of (A)
the Committed Revolving Line or (B) the Borrowing Base, minus, in each case, the
aggregate face amount of all Letters of Credit. Amounts borrowed pursuant to
this Section 2.1 (a) may be repaid and reborrowed at any time prior to the
earlier to occur of (i) the Revolving Maturity Date, at which time all Revolving
Advances under this Section 2.1 (a) shall be immediately due and payable or
(ii) the termination of Bank's obligation to advance money pursuant to Section
9.1(b).

                    (ii) Whenever Borrower desires a Revolving Advance, Borrower
shall notify Bank (which notice shall be irrevocable) by facsimile transmission
or telephone to he received no later than 3:00 p.m. Eastern Standard Time, on
the Business Day that the Revolving Advance is to be made. Each such
notification shall be promptly confirmed by a

                                       1.

<PAGE>

Payment/Advance Form in substantially the form of Exhibit C. The notice shall be
signed by a Responsible Officer or his or her designee. Bank is authorized to
make Revolving Advances under this Agreement, based upon instructions received
from a Responsible Officer or a designee of a Responsible Officer, or without
instructions if in Bank's discretion such Revolving Advances are necessary to
meet Obligations which have become due and remain unpaid. Bank shall be entitled
to rely on any telephonic notice given by a person who Bank reasonably believes
to be a Responsible Officer or a designee thereof, and Borrower shall indemnify
and hold Bank harmless for any damages or loss suffered by Bank as a result of
such reliance. Bank will credit the amount of Revolving Advances made under this
Section 2.1(a) to Borrower's deposit account maintained with Bank.

                    (iii) Borrower shall use Revolving Advances solely for
working capital and general corporate purposes.

               (b) Letter of Credit Usage. Subject to the availability under the
Committed Revolving Line and in reliance on the representations and warranties
of Borrower set forth herein, at any time and from time to time from the date
hereof through the Business Day immediately prior to the Revolving Maturity
Date, Bank shall issue for the account of Borrower such standby or commercial
letters of credit (each, a "Letter of Credit" and collectively, "Letters of
Credit") in an aggregate face amount not to exceed the least of (i) the
Committed Revolving Line minus the sum of (a) the aggregate principal amount of
the outstanding Revolving Advances at the time of issuance of such Letter of
Credit plus (b) the aggregate face amount of all outstanding Letters of Credit
at the time of issuance of such Letters of Credit, (ii) the Borrowing Base minus
the sum of (a) the aggregate principal amount of the outstanding Revolving
Advances at the time of issuance of such Letter of Credit plus (b) the aggregate
face amount of all outstanding Letters of Credit at the time of issuance of such
Letter of Credit and (iii) One Million Dollars ($1,000,000). The request for
such Letters of Credit shall be made by delivering to Bank a duly executed
letter of credit application on Bank's standard form. All Letters of Credit
shall be in form and substance acceptable to Bank in its sole discretion and
shall be subject to the terms and conditions of Bank's form application and
letter of credit agreement (the "Application"). Borrower will pay any standard
issuance and other fees that Bank notifies Borrower will be charged for issuing
and processing Letters of Credit for Borrower. On any drawn but unreimbursed
Letter of Credit, the unreimbursed amount shall be deemed a Revolving Advance
under Section 2.1(a). No Letter of Credit shall have an expiration date which is
later than the Revolving Maturity Date unless Borrower shall deposit with Bank
cash collateral in an amount equal to or greater than one hundred five percent
(105%) of the undrawn face amount of all such outstanding Letters of Credit.

                    (i) The obligation of Borrower to reimburse Bank for
drawings made under Letters of Credit shall be absolute, unconditional and
irrevocable, and shall be performed strictly in accordance with the terms of
this Agreement, the Application, and such Letters of Credit, under all
circumstances whatsoever. Borrower shall indemnify, defend, protect, and hold
Bank harmless from any loss, cost, expense or liability, including, without
limitation, reasonable attorneys' fees, arising out of or in connection with any
Letters of Credit, except for losses, costs, expenses or liabilities caused by
Bank's gross negligence or willful misconduct.

                                       2.

               (c)  Equipment Advances.

                    (i) Bank agrees to make an advance ("Equipment Advance") to
Borrower, in an aggregate outstanding amount not to exceed the Equipment Line.
The Equipment Advance shall not exceed (i) for new equipment with invoices dated
from September 20, 2002 through the Closing Date, one hundred percent (100%) of
the invoice amount, less taxes, freight, installation and other soft costs, (ii)
for equipment with invoices dated June 1, 2002 through September 20, 2002, one
hundred percent (100%) of the invoice amount, less taxes, freight, installation
and other soft costs, discounted for the number of months that such invoices are
dated prior to September 20, 2002, and (iii) for equipment purchased prior to
June 1, 2002, ninety percent (90%) of the forced sale value of such equipment as
determined by an appraiser approved by Bank. All such equipment invoices shall
be approved by Bank.

                    (ii) Borrower shall provide notice to Bank of the requested
Equipment Advance in substantially in the form of the Payment/Advance Form
attached hereto as Exhibit C. The notice shall be signed by a Responsible
Officer or his or her designee and include a copy of the invoice for any
Equipment to be financed, and shall include the serial numbers of such
equipment.

          2.2 Overadvances. If, at any time, (a) the aggregate amount of the
outstanding Revolving Advances exceeds the amounts permitted to be borrowed
under Section 2.1(a)(i); or (b) the aggregate amount of the outstanding
Equipment Advances exceeds the Equipment Line, Borrower shall immediately pay to
Bank, in cash, the amount of such excess.

          2.3  Principal Repayments.

               (a) Revolving Loans. All Revolving Advances shall be due and
payable on the Revolving Maturity Date.

               (b) Equipment Advances. The Equipment Advance shall be due and
payable in thirty-six (36) equal monthly installments of principal, beginning on
January 1, 2003 and continuing on the first day of each month thereafter through
the Equipment Maturity Date, at which time all amounts due in, connection with
Equipment Advances made under Section 2.1(c), along with accrued but unpaid
interest thereon, shall be immediately due and payable.

          2.4  Interest Rates, Payments, and Calculations.

               (a) Interest Rates.

                    (i) Revolving Advances. Except as set forth in Section
2.4(b), the Revolving Advances shall bear interest, on the outstanding daily
balance thereof, at a rate equal to One and Three Quarters of One Percent
(1.75%) above the Prime Rate.

                    (ii) Equipment Advances. Except as set forth in Section
2.4(b), the Equipment Advances shall bear interest, on the outstanding daily

<PAGE>

               (b) Late Fee; Default Rate. If any payment is not made within ten
(10) days after the date such payment is due, Borrower shall pay Bank a late fee
equal to the lesser of (i) five percent (5%) of the amount of such unpaid amount
or (ii) the maximum amount permitted to be charged under applicable law. All
Obligations shall bear interest, from and after the occurrence and during the
continuance of an Event of Default, at a rate, equal to five (5) percentage
points above the interest rate applicable immediately prior to the occurrence of
the Event of Default.

               (c) Payments. Interest on Revolving Advances and Equipment
Advances hereunder shall be due and payable in arrears on the first day of each
month during the term hereof. Bank may, at its option, charge such interest, all
Bank Expenses, and all Periodic Payments against any of Borrower's deposit
accounts or against the Committed Revolving Line, in which case those amounts
shall thereafter accrue interest at the rate then applicable hereunder. Any
interest not paid when due shall be compounded by becoming a part of the
Obligations, and such interest shall thereafter accrue interest at the rate then
applicable hereunder.

               (d) Computation. In the event the Prime Rate is changed from time
to time hereafter, the applicable rate of interest hereunder shall be increased
or decreased, effective as of the day the Prime Rate is changed, by an amount
equal to such change in the Prime Rate. All interest chargeable under the Loan
Documents shall be computed on the basis of a 360 day year for the actual number
of days elapsed.

          2.5 Crediting Payments. Prior to the occurrence of an Event of
Default, Bank shall credit a wire transfer of funds, check or other item of
payment to such deposit account or Obligation as Borrower specifies. After the
occurrence and during the continuance of an Event of Default, the receipt by
Bank of any wire transfer of funds, check, or other item of payment shall be
immediately applied to conditionally reduce Obligations, but shall not be
considered a payment on account unless such payment is of immediately available
federal funds or unless and until such check or other item of payment is honored
when presented for payment. Notwithstanding anything to the contrary contained
herein, any wire transfer or payment received by Bank after 12:00 noon Pacific
Standard Time shall be deemed to have been received by Bank as of the opening of
business on the immediately following Business Day. Whenever any payment to Bank
under the Loan Documents would otherwise be due (except by reason of
acceleration) on a date that is not a Business Day, such payment shall instead
be due on the next Business Day, and additional fees or interest, as the case
may be, shall accrue and be payable for the period of such extension.

          2.6 Fees. Borrower shall pay to Bank the following:

               (a) Revolving Commitment Fee. On the Closing Date, a Revolving
Commitment Fee equal to Fifty Thousand Dollars ($50,000).

Twenty Five Thousand Dollars ($25,000) per year, payable quarterly in advance,
which amount, once paid, is not refundable;

                                       4.

<PAGE>

               (c) Equipment Commitment Fee. On the Closing Date, an Equipment

               (d) Bank Expenses. On the Closing Date, all Bank Expenses
incurred through the Closing Date, including reasonable attorneys' fees and
expenses and, after the Closing Date, all Bank Expenses, including reasonable
attorneys' fees and expenses, as and when they become due.

          2.7 Term. This Agreement shall become effective on the Closing Date
and, subject to Section 12.7, shall continue in full force and effect for a
term ending on the Equipment Maturity Date.

          2.8 Prepayment; Reduction of Committed Revolving Line. Upon two (2)
Business Days prior written notice to Bank, Borrower may prepay the Credit
Extensions in whole or in part without premium or penalty. Any partial
prepayment must be in a principal amount of at least Fifty Thousand Dollars
($50,000) or an integral multiple of Ten Thousand Dollars ($10,000) in excess
thereof. Upon two (2) Business Days prior written notice to Bank, Borrower may
reduce or terminate the Committed Revolving Line to an amount not less than the
then outstanding principal amount of all Revolving Advances; provided, that any
partial reduction shall be in amount not less than Fifty Thousand Dollars
($50,000) or an integral multiple of Ten Thousand Dollars ($10,000) in excess
thereof. Once reduced in accordance with this section, the Committed Revolving

Payment/Advance Form and on the effective date of each Credit Extension as

occurred and be continuing, or would exist after giving effect to such Credit
Extension (provided, however, that those representations and warranties
expressly referring to another date shall be true and correct in all material
respects as of such date). The making of each Credit Extension shall be deemed
to be a representation and warranty by Borrower on the date of such Credit
Extension as to the accuracy of the facts referred to in this Section 3.2.

          4.1 Grant of Security Interest. Borrower grants and pledges to Bank a

arising Collateral to secure prompt repayment of any and all Obligations and to
secure prompt performance by Borrower of each of its covenants and duties under

Permitted Liens, such security interest constitutes a valid, first priority
security interest in the presently existing Collateral, and will constitute a
valid, first priority security interest in later-acquired Collateral.
Notwithstanding any termination, Bank's Lien on the Collateral shall remain in
effect for so long as any Obligations are outstanding.

          4.2 Delivery of Additional Documentation Required. Borrower shall from
time to time execute and deliver to Bank, at the request of Bank, all Negotiable

<PAGE>

     5.   Representations And Warranties.

          Borrower represents and warrants as follows:

          5.1 Due Organization and Qualification. Borrower and each Subsidiary
is a corporation duly existing under the laws of its jurisdiction of
incorporation and qualified and licensed to do business in any state in which
the conduct of its business or its ownership of property requires that it be so
qualified, except where the failure to do so could not reasonably be expected to
cause a Material Adverse Effect.

          5.2 Due Authorization; No Conflict. The execution, delivery, and
performance of the Loan Documents are within Borrower's corporate powers, have
been duly authorized by all necessary corporate actions on the part of Borrower,
and are not in conflict with nor constitute a breach of any provision contained
in Borrower's Certificate of Incorporation or Bylaws, nor will they constitute
an event of default under any material agreement by which Borrower is bound.
Borrower is not in default under any agreement by which it is bound, which
default could reasonably be expected to have a Material Adverse Effect.

          5.3 Collateral. Borrower has good title to the Collateral, free and
clear of Liens, except for Permitted Liens. The Eligible Accounts are bona fide
existing obligations. The property or services giving rise to such Eligible
Accounts has been delivered to the account debtor or its agent for immediate
shipment to and unconditional acceptance by the account debtor or have been
fully and completely performed. Borrower has not received notice of actual or
imminent Insolvency Proceeding of any account debtor whose accounts are included
in any Borrowing Base Certificate as an Eligible Account. All Inventory is in
all material respects of good and marketable. quality, free from all material
defects, except for Inventory for which adequate reserves have been made in
accordance with GAAP.

          5.4 Intellectual Property. Borrower is the sole owner of its
Intellectual Property, except for Licenses granted by Borrower to others in the
ordinary course of business and Permitted Liens. Each of the Copyrights,
Trademarks and Patents is valid and enforceable, and no part of the Borrower's
Intellectual Property has been judged invalid or unenforceable, in whole or in
part, and no claim has been made that any part of its Intellectual Property
violates the rights of any third party except to the extent such claim could not
reasonably be expected to cause a Material Adverse Effect. Except as set forth
in the Disclosure Letter, Borrower's rights as a licensee of intellectual
property do not give rise to more than five percent (5%) of its gross revenue in
any given month, including, without limitation, revenue derived from the sale,
licensing, rendering or disposition of any product or service.

          5.5 Name; Location of Chief Executive Office. Except as disclosed in
the Disclosure Letter, Borrower has not done business under any name other than
that specified on the signature page hereof. The chief executive office of
Borrower is located at the address indicated in Section 10 hereof.

          5.6 Litigation. Except as set forth in the Disclosure Letter, there
are no actions or proceedings pending by or against Borrower or any Subsidiary
before any court or administrative agency in which a likely adverse decision
could reasonably be expected to have a

                                       7.

<PAGE>

Material Adverse Effect, or a material adverse effect on Borrower's interest in
or Bank's security interest in the Collateral.

          5.7 No Material Adverse Change in Financial Statements. All
consolidated financial statements of the Borrower and its Subsidiaries that are
delivered by Borrower to Bank fairly present in all material respects Borrower's
consolidated financial condition as of the date thereof and Borrower's
consolidated results of operations for the period then ended. There has not been
a material adverse change in the consolidated financial condition of Borrower
since the date of the most recent of such financial statements submitted to
Bank.

          5.8 Solvency, Payment of Debts. Borrower is able to pay its debts
(including trade debts) as they mature; the fair saleable value of Borrower's
assets (including goodwill minus disposition costs) exceeds the fair value of
its liabilities; and Borrower is not left with unreasonably small capital after
the transactions contemplated by this Agreement.

          5.9 Compliance with Laws and Regulations. Borrower and each Subsidiary
have met the minimum funding requirements of ERISA with respect to any employee
benefit plans subject to ERISA. No event has occurred resulting from Borrower's
failure to comply with ERISA that is reasonably likely to result in Borrower's
incurring any liability that could have a Material Adverse Effect. Borrower is

becomes aware thereof; provided, however, that if the default cannot by its
nature be cured within the fifteen (15) day period or cannot after diligent

agency, and the same is not paid within ten (10) days if within the Unites
States or within thirty (30) days if outside of the United States, after
Borrower receives notice thereof, provided that none of the foregoing shall
constitute an Event of Default where

                                       15.

<PAGE>

such action or event is stayed or an adequate bond has been posted pending a

continuation statements and amendments thereto, relative to any of the

protect Bank from the exposure created by such failure; or (c) obtain and
maintain insurance policies of the type discussed in Section 6.5 of this

prudent. Any amounts so paid or deposited by Bank shall constitute Bank
Expenses, shall be immediately due and payable, and shall bear interest at the
then applicable rate hereinabove provided, and shall be secured by the
Collateral. Any payments made by Bank shall not constitute an agreement by Bank
to make similar payments in the future or a waiver by Bank of any Event of
Default under this Agreement.

Agreement, the Loan Documents, and all other agreements shall be cumulative.

provided under the UCC, by law, or in equity. No exercise by Bank of one right
or remedy shall be deemed an election, and no waiver by Bank of any Event of
Default on Borrower's part shall be deemed a continuing waiver. No delay by Bank
shall constitute a waiver, election, or acquiescence by it. No waiver by Bank
shall be effective unless made in a written document signed on behalf of Bank
and then shall be effective only in the specific instance and for the specific
purpose for which it was given.

                              STANDSTILL AGREEMENT

              This SECOND AMENDED AND RESTATED STANDSTILL AGREEMENT, dated as of
January 31st, 2003, by and among Atlantic Realty Trust, a Maryland real estate
investment trust ("ART") on the one hand and Kimco Realty Corporation, a
Maryland corporation ("KRC"), Kimco Realty Services, Inc., a Delaware
corporation ("KRS"), and Milton Cooper ("Cooper") on the other hand (each of
KRC, KRS and Cooper, are referred to herein, collectively, as "Kimco") (the
"Standstill Agreement").

                                    RECITALS:

              WHEREAS, Kimco has filed a Schedule 13D, as amended, under the
Securities Exchange Act of 1934, as amended (the "Exchange Act") with the
Securities and Exchange Commission, indicating Kimco's ownership of common
shares of beneficial interest, par value $.01 per share, of ART (the "Shares");

              WHEREAS, ART's charter limits the number of Shares that may be
owned, actually or constructively pursuant to the attribution rules set forth in
Section 544 of the Internal Revenue Code of 1986, as amended (the "Code"), as
such rules are modified by Section 856(h) of the Code or in Section 318(a) of
the Code as such rules are modified by Section 856(d)(5) of the Code
(constructive ownership of stock pursuant to such attribution rules is
hereinafter referred to as "Constructive Ownership," and the terms
"Constructively Own" and "Constructive Owner" shall have the correlative
meanings) by any person to 9.8% of the total number of Shares that are issued
and outstanding (the "Excess Share Provisions"). All Shares Constructively Owned
by any of KRC, KRS or Cooper in excess of 9.8% of the total number of Shares
that are issued and outstanding are referred to herein as "Excess Shares";

              WHEREAS, under the Charter, the Excess Shares are automatically
transferred to a charitable trust to be held for sale unless ART's board of
trustees, in accordance with the Excess Share Provisions, grants an exception to
such ownership limit provisions with respect to the Excess Shares (a "Waiver");

              WHEREAS, Kimco previously requested that ART, acting through its
Board of Trustees, grant Kimco a Waiver;

              WHEREAS, ART, acting through its Board of Trustees, agreed to
grant Kimco a Waiver and in connection therewith ART and Kimco entered into a
Standstill Agreement dated April 30, 1998 (the "Original Standstill Agreement")
pursuant to which Kimco and certain affiliates, agreed, among other things, not
to acquire more than 25% of the issued and outstanding shares of ART;

              WHEREAS, on June 21, 2000 Kimco requested that ART amend the
Original Standstill Agreement in order to permit Kimco and certain of its
affiliates to own up to 30% of the issued and outstanding shares of ART and,
accordingly, increase the size of the Excess Shares Waiver and whereas such
amendment went into effect on July 21, 2000;

<PAGE>

              WHEREAS, Kimco requested that ART amend the Amended and Restated
Standtill Agreement in order to permit Kimco and certain of its affiliates to
own up to 33% of the issued and outstanding shares of ART and, accordingly,
increase the size of the Excess Shares Waiver; and

              WHEREAS, ART, acting through its Board of Trustees, has agreed to
increase the size of the Waiver on the condition that Kimco enter into this
Second Amended and Restated Standstill Agreement and Kimco has agreed to comply
with this condition.

              NOW, THEREFORE, in consideration of the mutual covenants and
agreements set forth herein and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

              1.   STANDSTILL.

                   (a)  GENERAL STANDSTILL. Kimco hereby agrees that they shall
not, and they shall cause their Affiliated Persons (as defined below) not to
directly or indirectly through an Affiliated Person, unless specifically
requested in writing in advance by the ART board of trustees:

                       (i)   acquire, agree to acquire, or make a public offer
or proposal to acquire, in any manner, directly or indirectly through an
Affiliated Person, ownership or control of

                             (A)  any securities of ART ("Restricted
Securities") in excess of 33% of the total number of shares that are issued and
outstanding, or

                             (B)  any subsidiary or any assets or properties of
ART or any subsidiary or division thereof, including by way of any fundamental
transaction with ART, such as a tender offer, business combination, merger or
other consolidation,

                      (ii)   make any "solicitation" of "proxies" (as such terms
are used in the proxy rules of the Securities and Exchange Commission) to vote
any voting securities of ART,

                     (iii)   form or join a "group" (as defined in Section
13(d)(3) of the Exchange Act) in connection with any of the provisions of this
Section 1, other than a group consisting solely of two or more of KRC, KRS,
Cooper and any Affiliated Persons, and

                      (iv)   disclose any intention, plan or arrangement
inconsistent with the provisions of this Section 1.

The provisions of this Section 1 are referred to in this Standstill Agreement,
collectively, as "Restricted Activities". Notwithstanding the foregoing, nothing
in this Section 1 shall prohibit Kimco or its Affiliated Persons from making a
proposal to acquire any asset or property that ART announces an intention to
sell or is soliciting acquisition proposals from third parties.

                                       2

<PAGE>

                   (b)  VOTING RIGHTS. Subject to the terms of this Standstill
Agreement, Kimco may vote its shareholdings of ART in its sole and absolute
discretion; provided, however, Kimco shall vote any Excess Shares in accordance
with the recommendation of the ART board of trustees.

                   (c)  "Affiliated Person" shall mean, for the purposes of this
Standstill Agreement, (i) any corporation, limited liability company or
partnership of which Kimco Realty, Kimco Services or Mr. Cooper, individually or
in the aggregate, own a majority of the voting securities (or, in the case of a
limited liability company or partnership, a majority of the economic interest or
limited partnership interests, respectively) or serve as a managing member or
general partner and (ii) Mr. Cooper's spouse, and any relative of Mr. Cooper or
his spouse who has the same home as Mr. Cooper and any trust in which Mr. Cooper
or his spouse has a substantial beneficial interest or as to which Mr. Cooper
serves as trustee or in a similar fiduciary capacity.

                  2.   RELEASE.

                  (a) Kimco, on behalf of themselves and for each of their
heirs, executors, administrators, successors, and/or assigns (collectively, the
"Kimco Releasor"), hereby remises, releases, and forever discharges each of ART,
their direct and indirect subsidiaries, shareholders, affiliates, subdivisions,
predecessors, successors or assigns, and their present and former directors,
officers, employees, agents and attorneys and their heirs, executors,
administrators, successors, and assignees (collectively, the "ART Releasees"),
and each of them, of and from any and all claims, demands, or causes of action
whatsoever from the beginning of the world to the date present, whether
individual, class or derivative in nature, at law or in equity, whether based on
any federal, state, or foreign law or right of action, foreseen or unforeseen
matured or unmatured, know or unknown, accrued or not accrued, which the Kimco
Releasor has, had or have or can, shall, or may hereafter have against the ART
Releasees, or any of them, alleged or which could have been alleged or arising
out of or relating to the decision by ART's Board of Directors to approve, and
ART's execution and delivery of, the tax agreement dated May 10, 1996 by and
between Ramco-Gershenson Properties Trust (together with its subsidiaries,
"RPT") or any amounts paid by ART to RPT or to the Internal Revenue Service
pursuant to its obligations under such agreement; provided, however, that this
release shall be ineffective with respect to each ART Releasee if any person
whose vote was required to approve such decision received or stands to receive,
directly or indirectly, any benefit as a result thereof other than his or her
pro rata benefit as a securityholder of RPT. Kimco hereby acknowledges that all
amounts paid to Joel M. Pashcow, Herbert Liechtung, the members of the Special
Acquisition Committee and Wolf Block (as such terms are defined below) in
connection with the acquisition of substantially all the property and assets of
Ramco-Gershenson, Inc. and its affiliates by RPS Realty Trust ("RPS") as
described in RPS's Proxy Statement dated March 29, 1996 (the "Proxy Statement")
shall not be deemed to be a benefit for this purpose. Capitalized terms used but
not otherwise defined in this Section 2 shall have the meanings set forth in the
Proxy Statement.

                   3.  WAIVER. Kimco acknowledges its understanding that, as set
forth in the Recitals to this Standstill Agreement, ownership of the Shares is
subject to the Excess Share Provisions. Subject to the terms and conditions of
this Standstill Agreement, ART grants to Kimco a Waiver with respect to the
Excess Shares, but only with respect to Excess Shares that

                                       3

<PAGE>

do not exceed 23.2% of the total number of Shares that are currently issued and
outstanding. Kimco understands and agrees that ART's grant to Kimco of the
Waiver is conditioned upon the continuing accuracy of the representations and
warranties set forth in Section 4 of this Standstill Agreement and upon such
Waiver otherwise not causing ART to fail to qualify as a REIT for income tax
purposes, and Kimco further understands and agrees that, subject to the Waiver,
if any such Excess Share Provisions are hereafter violated by it or if any of
such representations and warranties cease to be true, the Excess Shares may be
automatically transferred to a trust for the benefit of a charitable beneficiary
(as set forth in the Excess Share Provisions) and that, if so transferred, the
applicable shareholder's ownership rights in such Excess Shares will be
terminated. ART agrees that the remedies provided in its charter shall be the
sole remedies available to ART in the event that any of the representations and
warranties of Kimco set forth in Section 4 of this Standstill Agreement ceased
to be true or the ownership of Shares by Kimco otherwise would violate any of
the restrictions set forth in the ART's charter.

                   4.  REPRESENTATIONS AND WARRANTIES OF KIMCO. Kimco hereby
jointly and severally represents and warrants to, and agrees with, ART as
follows:

                   (a) CAPACITY; ENFORCEABILITY. Each of the Kimco persons
executing this Standstill Agreement has full capacity and authority, and
corporate authority and capacity, as the case may be, to execute and deliver
this Standstill Agreement. This Standstill Agreement has been duly and validly
executed and delivered by and on behalf of each of them and constitutes a valid
obligation of each of them, enforceable in accordance with its terms, except to
the extent such enforceability may be limited by applicable insolvency,
bankruptcy, reorganization or similar laws affecting the enforcement of
creditors' rights generally and by general equity principles.

                   (b) NO CONFLICT. The performance of this Standstill
Agreement and the consummation of the transactions contemplated hereby will not
result in a breach or violation of any of the terms or provisions of, or
constitute a default under:

                       (i)   the certificate of incorporation of KRC or KRS,

                      (ii)   the by-laws of KRC or KRS,

                     (iii)   any contract or other agreement or instrument to
which Kimco is a party or by which Kimco is bound, the breach of which would
have a material adverse effect on ART or Kimco, or

                      (iv)   any law, order, rule, regulation, writ, injunction
or decree applicable to Kimco.

|                  (c) GOVERNMENTAL APPROVALS. No consent, authorization
or approval of, exemption by, or filing with, any domestic governmental or
administrative authority, or any court, is required to be obtained or made by
Kimco in connection with the execution, delivery and performance of this
Standstill Agreement or the consummation of the transactions contemplated
hereby.

                                       4

<PAGE>

                   (d) EXCESS OWNERSHIP. KRC and KRS are corporations and, to
the best of Kimco's knowledge (after due investigation), no person or entity
which would be treated as an individual for purposes of Section 542(a)(2) of the
Code, as modified by Section 856(h) of the Code, Constructively Owns in excess
of 9.8% of the value of the outstanding equity interest in KRC or KRS.

|                  (e) UPDATE OF REPRESENTATIONS. At the reasonable request of
ART from time to time, Kimco will update its representations to ART set forth in
Section 5(d).

                   (f) RELATED TENANTS RENT. ART has provided to Kimco an
accurate list of its and its subsidiaries current tenants and, to the knowledge
of Kimco, the amount of annualized rents payable to ART or to its subsidiaries
by all such tenants of ART or its subsidiaries in which Kimco owns 10 percent or
more of the stock or other ownership interest computed in accordance with the
attribution rules of Code Section 318(a), as modified by Code Section 856(d)(5)
("Related Tenants") (such as to exclude such rents from the term "rents from
real property" by reason of Section 856(d)(2)(B) of the Code) do not exceed
$25,000. At the reasonable request of ART from time to time and upon receipt by
Kimco of a current list of ART's and its subsidiaries tenants, Kimco will update
its representation with respect to its then ownership interests (if any) in such
tenants of ART or its subsidiaries and provide ART with such information
concerning rents payable by Related Tenants as ART may reasonably request in
connection with maintaining ART's status as a REIT.

                  5.   Representations and Warranties of ART. ART hereby
represents and warrants to, and agrees with, Kimco as follows:

                  (a) CAPACITY; ENFORCEABILITY. ART has full trust authority and
capacity to execute and deliver this Standstill Agreement. This Standstill
Agreement has been duly and validly executed and delivered by and on behalf of
ART and constitutes a valid obligation of ART, enforceable in accordance with
its terms, except to the extent such enforceability may be limited by applicable
insolvency, bankruptcy, reorganization or similar laws affecting the enforcement
of creditors' rights generally and by general equity principles.

                  (b)  NO CONFLICT. The performance of this Standstill Agreement

                   (i) SEVERABILITY. If and to the extent that any court of
competent jurisdiction holds any provision (or any part thereof) of this
Standstill Agreement to be invalid or unenforceable, such holding shall in no
way affect the validity of the remainder of this Standstill Agreement, including
any provision, in any other jurisdiction, it being intended that all rights and
obligations of the parities hereunder shall be enforceable to the fullest extent
permitted by law; provided, however, that if the Waiver is finally determined by

Agreement shall terminate.

                   (j)  EXECUTION. Facsimiles of executed copies of this

binding upon and inure to the benefit of the parties hereto and their respective
successors, legal representatives and assigns.

                   (m)  WAIVER OF COMPLIANCE. Any failure of any of the parties
to comply with any obligation, covenant, agreement, or condition herein may be
waived by the party or parties entitled to the benefits thereof only by a
written instrument signed by the party granting such waiver, but such a waiver
or failure to insist upon strict compliance with such obligation, covenant,
agreement or condition shall not operate as a waiver of, or estoppel with
respect to, any subsequent other failure.

                   (n) FURTHER ASSURANCES. The parties to this Standstill
Agreement, without further consideration, use all reasonable efforts to execute

may reasonably request to carry out the intent of this Standstill Agreement and
the transactions contemplated hereby.

                   (o) EQUITABLE PRINCIPLES. The parties acknowledge and agree
that irreparable damage would occur in the event any of the provisions of this
Standstill Agreement were not performed in accordance with their specific terms
or were otherwise breached. It is accordingly agreed that the parties shall be
entitled to seek an injunction to prevent any breach of the provisions of this
Standstill Agreement and to enforce specifically the terms and provisions hereof
in any court having jurisdiction, in addition to any other remedy to which they
may be entitled at law or in equity.
