                                  ARTICLE II
                    MEMBERSHIP INTEREST CONTRIBUTION; CLOSING
     2.1 Contribution of the Membership Interests. On the terms and subject to
         ----------------------------------------
the conditions set forth in this Agreement, the LLC agrees to contribute and
deliver to the Operating Partnership, and the Operating Partnership agrees to
accept from the LLC (the "Acquisition"), in exchange for the consideration set
forth in Section 2.2 below, all of issued and outstanding membership interests
(the "Membership Interests") of each of the subsidiaries of the LLC as set forth
on Schedule 2.1 (the "Subsidiaries").
     2.2 Consideration. The consideration to be paid by the Operating
         -------------
Partnership to the LLC in connection with the Acquisition shall be the number of
Operating Partnership units (the "Operating Partnership Units") set forth in
Schedule 2.2 representing a limited partnership interest in the Operating
------------
Partnership with the rights and preferences as set forth in the Operating
Partnership Agreement, a copy of which is attached hereto as Exhibit A. The
Operating Partnership Units shall be granted and delivered to the LLC at
Closing. In addition to receiving the number of Operating Partnership Units as
set forth on Schedule 2.2, the LLC shall also receive a total cash payment of
$400,000.00.

         --------------------------
"Closing") shall take place on October 1, 2001 (effective September 30, 2001 at

     2.4 Contribution Adjustment.
         -----------------------
         (a)   Prior to the Closing, the Subsidiaries shall distribute to the
               LLC all of the cash assets of the Subsidiaries except the
               Subsidiaries shall retain sufficient cash to satisfy all accrued
               expenses and accounts payable accruable through the Closing. To
               the extent that the Subsidiaries do not have sufficient cash to
               satisfy all accrued expenses and accounts payable accruals, then
               the LLC shall contribute such deficit to the Operating
               Partnership. To the extent that the Subsidiaries have excess cash
               to satisfy all accrued expenses and accounts payable accruals,
               then the Subsidiaries shall refund such excess to the LLC. The
               deficit or excess, as the case may be, shall be referred to as
               the "Contribution Adjustment."
                                      -4-
         (b)   The Operating Partnership shall deliver its calculation of the
               Contribution Adjustment (the "Contribution Adjustment Notice") to
               the LLC within 30 days of Closing. The LLC may object to the
               Contribution Adjustment by delivery of a written statement of
               objections (stating the basis of the objections with reasonable
               specificity) to Operating Partnership within 10 days following
               delivery of the Contribution Adjustment Notice. If LLC makes such
               objection, the Operating Partnership and LLC shall seek in good
               faith to resolve such differences within 10 days following the
               delivery of such objections. If LLC does not so object to the
               Contribution Adjustment within such 10 day period, the
               Contribution Adjustment shall be considered final and binding
               upon the parties and the Contribution Adjustment shall be made
               within 45 days of Closing . If LLC and the Operating Partnership
               are unable to mutually resolve any disputes with respect to the
               Contribution Adjustment within the periods described above, the
               parties shall, within 10 days following the expiration of such
               periods, engage a mutually agreed upon Mediator (the "Mediator")
               to act as a Mediator and determine, in accordance with the
               provisions of this Section 2.4, the appropriate Contribution
               Adjustment.
         (c)   If the Mediator is engaged pursuant to this Section 2.4, then,
               within 10 days of the engagement, the Mediator shall be furnished
               with a copy of this Agreement, a letter from LLC describing LLC's
               position on the disputed amount and a letter from Operating
               Partnership describing Operating Partnership's position on the
               disputed amount. Neither party shall make any additional
               submission except pursuant to the Mediator's written request. The
               Mediator shall have 30 days to review such documents and such
               other information as the Mediator deems appropriate. Within such
               30-day period, the Mediator will furnish both parties with its
               written determination with respect to each of the unresolved
               issues in dispute. In arriving at its determination, the Mediator
               may select either the LLC's or the Operating Partnership's
               position, or make its own determination. The determination of the
               Mediator with respect to the Contribution Adjustment will be
               final and binding upon the parties and a judgment, based on the
               Mediator's determination, may be entered into a court of
               competent jurisdiction. The Contribution Adjustment shall be made
               within 5 days after the Mediator's determination. The fee of the
               Mediator shall be borne by the Operating Partnership, if the
               mediator accepts LLC's position, by the LLC, if the Mediator
               accepts the Operating Partnership's position, and by the
               Operating Partnership and LLC equally if the Mediator accepts
               neither the Operating Partnership's nor the LLC's position. In
               the process of preparing and reviewing the Contribution
               Adjustment and conducting of review by either party or the
               Mediator, each party will grant the other party all reasonable
               access to the records of the business and any workpapers,
               including auditor's workpapers, prepared with respect to the
               Contribution Adjustment.

               thereto, or events that with notice or lapse of time or both
               would constitute defaults thereunder by the LLC or the

               contract, lease or sublease has given or received a written

          (b)  All Real Property is appropriately zoned under the applicable
               zoning ordinances of the city, county and state in which such the

               legal requirements applicable to the Real Property or any part
               thereof, or any property adjacent to the Real Property, or any
               moratorium that could or would in any way impair the use of the

               consents and approvals required by any such Governmental
               Authority for the continued use, occupancy and operation of the
               Real Property have been obtained, except for those the failure to
               obtain would not have a Material Adverse Effect on the LLC or any
               of the Subsidiaries.
          (d)  All improvements located on the Real Property are in good working
               order and repair (ordinary wear and tear excepted), free from

               except as presented in the Rent Roll, no party has any right to
               rent-free occupancy or rent reductions or concessions. No tenant
               is in default under their lease (as to rent or otherwise), except
               for such defaults which would not individually or in the
               aggregate have a Material Adverse Effect on any of the

               in accordance with its terms, subject to applicable bankruptcy,

               pursuant to Rule 144(k) under the Securities Act. The LLC shall
               furnish to Cornerstone such information regarding itself and the
               distribution of the Registered Shares covered by the Registration
               Statement as Cornerstone may from time to time reasonably request
               in writing and as shall be required under the Securities Act.
          (b)  Cornerstone shall notify the LLC and confirm such advice in
               writing (i) when the filing of any post-effective amendment to
               the Registration Statement or supplement to the Prospectus is
               required, when the same is filed and, in the case of the
               Registration Statement and any post-effective amendment, when the
               same becomes effective, (ii) of any request by the Securities and
               Exchange Commission for any amendment of or supplement to the
               Registration Statement or the Prospectus or for additional
               information and (iii) of the entry of any stop order suspending
               the effectiveness of the Registration Statement or the initiation
               or threatening of any proceedings for that purpose, and, if such
               stop order shall be entered, Cornerstone shall use its best
               efforts promptly to obtain the lifting thereof.
          (c)  Cornerstone shall furnish to the LLC, at Cornerstone's expense,
               such number of copies of the final Prospectus and of each
               post-effective amendment or supplement thereto, as may reasonably
               be required in order to facilitate the disposition of the
               Registered Shares in conformity with the requirements of the
               Securities Act and the rules and regulations promulgated
               thereunder, but only while Cornerstone is required under the
               provisions hereof to cause the Registration Statement to remain
               effective.
          (d)  Cornerstone shall use its best efforts to register or qualify
               such shares under such other securities or "blue sky" laws of
               such jurisdictions as the LLC reasonably requests and do any and
               all other acts and things which may be reasonably necessary or
               advisable to enable the LLC to consummate the disposition in such
               jurisdictions of the Registered Shares (provided that Cornerstone
               shall not be required to (i) qualify generally to do business in
               any jurisdiction in which it would not otherwise be required to
               qualify but for this Section 6.9, (ii) subject itself to taxation
               in any such
                                      -23-
               jurisdiction, or (iii) consent to general service of process in
               any such jurisdiction).
          (e)  Cornerstone shall take all steps necessary to enable the LLC to
               avail itself of the prospectus delivery mechanism set forth in
               Rule 153 under the Securities Act or any successor thereto.
          (f)  If any event, fact or circumstance requiring an amendment to the
               Registration Statement or a supplement to the Prospectus shall
               exist, Cornerstone shall, upon becoming aware thereof, promptly
               so notify the LLC and prepare and furnish to the LLC, and file
               with the Securities and Exchange Commission, a post-effective
               amendment to the Registration Statement or a supplement to the
               Prospectus or any document incorporated by reference therein, or
               file any other required document, so that, as thereafter
               delivered to the purchasers of Registered Shares, the Prospectus
               will not contain an untrue statement of a material fact or omit
               to state any material fact required to be stated therein or
               necessary to make the statements therein, in the light of the
               circumstances under which they were made, not misleading.
     6.10 Indemnification and Contribution with Respect to the Registration
          -----------------------------------------------------------------
Statement.
---------
          (a)  By Cornerstone. In connection with the registration under the
               --------------
               Securities Act of the Registered Shares for resale pursuant to
               Section 6.9, Cornerstone shall indemnify and hold harmless the
               LLC against any losses, claims, damages or liabilities, joint or
               several (or actions or proceedings, whether commenced or
               threatened, in respect thereof) ("Losses"), to which it may
               become subject, under the Securities Act or otherwise, but only
               to the extent such Losses arise out of or are based upon (1) any
               untrue statement or alleged untrue statement of any material fact
               contained, on the effective date thereof, in the Registration
               Statement, in any preliminary Prospectus (if used prior to the
               effective date of the Registration Statement) or in any final
               Prospectus or in any post-effective amendment or supplement
               thereto (if used during the period Cornerstone is required to
               keep the Registration Statement effective) including any document
               incorporated therein by reference (the "Disclosure Documents"),
               or (2) any omission or alleged omission to state in any of the
               Disclosure Documents a material fact required to be stated
               therein or necessary to make the statements made therein not
               misleading, or (3) any violation of any federal or state
               securities laws or rules or regulations thereunder committed by
               Cornerstone in connection with the performance of its obligations
               under Section 6.9; and Cornerstone will reimburse the LLC for all
               legal and other expenses reasonably incurred by it in
               investigating or defending against any such claims, whether or
               not resulting in any liability, or in connection with any
               investigation or proceeding by any governmental agency or
               instrumentality with respect to any offering of Registered Shares
               for resale pursuant to Section 6.9,
                                      -24-
               including any amounts paid in settlement of any action, suit,
               arbitration, proceeding, litigation or investigation
               (collectively "Litigation"), commenced or threatened, provided,
               however, that Cornerstone shall not be liable to an indemnified
               party in any such case to the extent that any such Losses arise
               out of or are based upon (i) an untrue statement or omission or
               alleged omission made in any such Disclosure Documents in
               reliance upon and in conformity with written information
               furnished to Cornerstone by the LLC for use therein, or (ii) the
               use of any Prospectus after such time as Cornerstone has advised
               the LLC in writing that the filing of a post-effective amendment
               or supplement thereto is required, except the Prospectus as so
               amended or supplemented, or the use of any Prospectus after such
               time as the obligation of Cornerstone to keep the same current
               and effective has expired.
          (b)  By LLC. In connection with the registration under the Securities
               ------
               Act of the Registered Shares for resale pursuant to Section 6.9,
               the LLC shall indemnify and hold harmless Cornerstone, each of
               its directors, each of its officers who have signed the
               Registration Statement, and each other person, if any, who
               controls Cornerstone within the meaning of Section 15 of the
               Securities Act against any Losses to which such indemnified party
               may become subject under the Securities Act or otherwise, but
               only to the extent such Losses arise out of or are based upon (i)
               any untrue statement or alleged untrue statement of any material
               fact contained in any of the Disclosure Documents or any omission
               or alleged omission to state therein a material fact required to
               be stated therein or necessary to make the statements therein not
               misleading, if the statement or omission was made in reliance
               upon and in conformity with written information furnished to
               Cornerstone by or on behalf of the LLC for use therein; (ii) the
               use by or on behalf of the LLC of any Prospectus after such time
               as Cornerstone has advised the LLC in writing that the filing of
               a post-effective amendment or supplement thereto is required,
               except the Prospectus as so amended or supplemented, or after
               such time as the obligation of Cornerstone to keep the
               Registration Statement effective and current has expired, or
               (iii) any information given or representation made by or on
               behalf of the LLC in connection with the resale of Registered
               Shares which is not contained in and not in conformity with the
               Prospectus (as amended or supplemented at the time of the giving
               of such information or making of such representation); and the
               LLC shall reimburse each such indemnified party for all legal and
               other expenses reasonably incurred by such party in investigating
               or defending against any such claims, whether or not resulting in
               any liability, or in connection with any investigation or
               proceeding by any governmental agency or instrumentality relating
               to any such claims with respect to any offering of the Registered
               Shares pursuant to Section 6.9, including any amounts paid in
               settlement of any Litigation, commenced or threatened.
                                      -25-
          (c)  Notice. If a third party commences any action or proceeding
               ------
               against an indemnified party related to any of the matters
               subject to indemnification under Section 6.10(a) or (b) hereof,
               such indemnified party shall promptly give notice to the
               indemnifying party in writing of the commencement thereof, but
               failure so to give notice shall not relieve the indemnifying
               party from any liability which it may have hereunder unless the
               indemnifying party is prejudiced thereby.
          (d)  Control of Defense. The indemnifying party shall be entitled to
               ------------------
               control the defense or prosecution of such claim or demand in the
               name of the indemnified party, with counsel satisfactory to the
               indemnified party, if it notifies the indemnified party in
               writing of its intention to do so within 30 days of its receipt
               of the notice from the indemnified party, subject, however, to
               the right of the indemnified party to participate therein through
               counsel of its own choosing, which participation shall be at the
               indemnified party's expense; provided, however, that if (i) the
               indemnified party shall have reasonably concluded that there are
               likely to be defenses available to it that are different from or
               additional to those available to the indemnifying party, or (ii)
               the indemnifying party shall fail vigorously to defend or
               prosecute such claim or demand within a reasonable time then in
               either case the indemnifying party shall not have the right to
               direct the defense of such action on behalf of the indemnified
               party and the indemnified shall have the right to employ separate
               counsel at the indemnifying party's expense and to control its
               own defense of such action. Whether or not the indemnifying party
               chooses to defend or prosecute such claim, the parties hereto
               shall cooperate in the prosecution or defense of such claim and
               shall furnish such records, information and testimony and attend
               such conferences, discovery proceedings, hearings, trials and
               appeals as may be requested in connection therewith.
          (e)  Contribution. If the indemnification provided for in subsections
               ------------
               (a) or (b) of this Section 6.10 is unavailable to or insufficient
               to hold the indemnified party harmless under subsections (a) or
               (b) above in respect of any Losses referred to therein for any
               reason other than as specified therein, then the indemnifying
               party shall contribute to the amount paid or payable by such
               indemnified party as a result of such Losses in such proportion
               as is appropriate to reflect the relative fault of the
               indemnifying party on the one hand and such indemnified party on
               the other in connection with the statements or omissions which
               resulted in such Losses, as well as any other relevant equitable
               considerations. The relative fault shall be determined by
               reference to, among other things, whether the untrue or alleged
               untrue statement of a material fact or the omission or alleged
               omission to state a material fact relates to information supplied
               by (or omitted to be supplied by) Cornerstone or the LLC and the
               parties' relative intent, knowledge, access to information and
               opportunity to correct or prevent such statement or omission. The
               amount paid or payable by an indemnified party as a result of the
               Losses referred to above
                                      -26-
               in this subsection (d) shall be deemed to include any legal or
               other expenses reasonably incurred by such indemnified party in
               connection with investigation or defending any such action or
               claim. No person guilty of fraudulent misrepresentation (within
               the meaning of Section 11(f) of the Securities Act) shall be
               entitled to contribution from any person who was not guilty of
               such fraudulent misrepresentation.
          (f)  Limitation of Liability of the LLC. The indemnification
               ----------------------------------
               obligation under Section 6.10(b), and the contribution obligation
               under Section 6.10(d), of the LLC shall be limited to the amount
               of net proceeds received by the LLC upon the resale of Registered
               Shares under the Registration Statement.
          (g)  Application. The provisions of Article IX shall not be applicable
               -----------
               to Section 6.9 and this Section 6.10.
     6.11 Financial Information. LLC acknowledges that Cornerstone is a public
          ---------------------
entity and that it may be required to furnish financial statements to the
Securities and Exchange Commission in connection with the Acquisition. LLC
agrees to make the information available for Cornerstone to audit the last 12
months of operation of the Subsidiaries so that a report can be generated that
is in compliance with accounting Regulation S-X of the Securities and Exchange
Commission.

indemnify another party to this Agreement under the provisions of this Article
with respect to claims resulting from the assertion of liability by Persons not
parties to this Agreement (including governmental claims for penalties, fines
and assessments) shall be subject to the following terms and conditions:
          (a)  The indemnified party shall give prompt written notice to the
               indemnifying party of any assertion of liability by a third party
               which might give rise to a claim for indemnification, which
               notice shall state the nature and basis of the assertion and the
               amount thereof, to the extent known, provided, however, that no
               delay on the part of the indemnified party in giving notice shall
               relieve the indemnifying party of any obligation to indemnify
               unless (and then solely to the extent that) the indemnifying
               party is prejudiced by such delay.
          (b)  If any action, suit or proceeding (a "Legal Action") is brought
               against an indemnified party with respect to which the
               indemnifying party may have an obligation to indemnify, the Legal
               Action shall be defended by the indemnifying party and such
               defense shall include all proceedings and appeals which counsel
               for the indemnified party shall reasonably deem appropriate.
          (c)  Notwithstanding the provisions of the previous subsection of this
               Article, until the indemnifying party shall have assumed the
               defense of any such Legal Action, the defense shall be handled by
               the indemnified party. Furthermore, (i) if the indemnified party
               shall have reasonably concluded that there are likely to be
               defenses available to the indemnified party that are different
               from or in addition to those available to the indemnifying party;
               (ii) if the indemnifying party fails to provide the indemnified
               party with evidence reasonably acceptable to the indemnified
               party that the indemnifying party has sufficient financial
               resources to defend and fulfill its indemnification obligation
               with respect to the Legal Action; (iii if the Legal Action
               involves other than money damages and seeks injunctive or other
               equitable relief; or (iv) if a judgment against the indemnified
               party will, in the good faith opinion of the indemnified party,
               establish a custom or precedent which will be materially adverse
               to the best interests of its continuing business, the
               indemnifying party shall not be entitled to assume the defense of
               the Legal Action and the defense shall be handled by the
               indemnified party. If the defense of the Legal Action is handled
               by the
                                      -31-
               indemnified party under the provisions of this subsection, the
               indemnifying party shall pay all legal and other expenses
               reasonably incurred by the indemnified party in conducting such
               defense.
          (d)  In any Legal Action initiated by a third party and defended by
               the indemnifying party (i) the indemnified party shall have the
               right to be represented by advisory counsel and accountants, at
               its own expense, (ii) the indemnifying party shall keep the
               indemnified party fully informed as to the status of such Legal
               Action at all stages thereof, whether or not the indemnified
               party is represented by its own counsel, (iii) the indemnifying
               party shall make available to the indemnified party, and its
               attorneys, accountants and other representatives, all books and
               records of the indemnifying party relating to such Legal Action
               and (iv) the parties shall render to each other such assistance
               as may be reasonably required in order to ensure the proper and
               adequate defense of the Legal Action.
          (e)  In any Legal Action initiated by a third party and defended by
               the indemnifying party, the indemnifying party shall not make any
               settlement of any claim without the written consent of the
               indemnified party, which consent shall not be unreasonably
               withheld. Without limiting the generality of the foregoing, it
               shall not be deemed unreasonable to withhold consent to a
               settlement involving injunctive or other equitable relief against
               the indemnified party or its assets, employees or business, or
               relief which the indemnified party reasonably believes could
               establish a custom or precedent which will be adverse to the best
               interests of its continuing business.
     9.4 Limitation on Indemnities.
         -------------------------
          (a)  Any provision of this Agreement to the contrary notwithstanding,
               no claim for indemnification by an indemnified party against an
               indemnifying party pursuant to this Article IX for any inaccuracy
               or misrepresentation in, or breach of any representation or
               warranty shall be valid and capable of assertion unless and until
               the aggregate amount of all claims against the indemnifying party
               exceeds $100,000 (the "Basket Amount"), but then the indemnified
               party may seek indemnification for the full amount of such
               claims.
          (b)  Any provision of this Agreement to the contrary notwithstanding,
               the maximum amount for which an indemnifying party may be liable
               to the indemnified party hereunder for any inaccuracy or
               misrepresentation in, or breach of any representation or warranty
               shall not exceed, in the aggregate, the sum of $11,576,526 ("Cap
               Amount").
          (c)  Notwithstanding anything to the contrary herein, no indemnified
               party shall be subject to the Basket Amount or the Cap Amount in
               seeking
                                      -32-
               indemnification from an indemnifying party involving fraud or
               willful or intentional misrepresentations.
          (d)  In the event that the LLC is the indemnifying party hereunder,
               the LLC shall have the option of transferring Operating
               Partnership Units to the Operating Partnership in partial or
               complete satisfaction of claims. The parties shall seek to treat
               any such claim which is satisfied through the transfer of
               Operating Partnership Units as a unit adjustment rather than a
               separate independent taxable event.

         --------
Operating Partnership in Article III and the LLC in Articles IV and V hereof
