Outsourced Product shall be entitled to be the exclusive supplier to Alliance of
such Product, subject to the following:

                              (A) with respect to courier services, Alliance
shall be entitled to offer its Customers any such services offered by Federal
Express, UPS, Airborne, DHL or the United States Postal Service;

                              (B) with respect to any particular geographic

an exclusive basis shall be able to meet the reasonable and actual demands of
Alliance for such Product (it being agreed and understood that the inability of
any RSI Entity to meet the reasonable and actual demands of Alliance for such
Product in any particular geographic market shall not affect such RSI Entity's
right to be the exclusive supplier in any other geographic market where it is
otherwise entitled to be the exclusive supplier);

                              (C) where an RSI Entity is acting as an exclusive
supplier of an RSI Reserved Outsourced Product, if from time to time such RSI
Entity is not able to timely meet the reasonable and actual demands of Alliance
with respect to such RSI Reserved Outsourced Product (after Alliance has given
the RSI Entity reasonable notice and the reasonable opportunity to supply the
Product in the specific instance, in each case, in light of the circumstances
with respect to such actual and reasonable demands, and, after such notice, the
RSI Entity is unable to timely do so), Alliance shall be entitled to utilize one
or more Third Parties to supplement the capabilities of the RSI Entity in
question when necessary;

                              (D) with respect to catering and food service,
Alliance shall be entitled to use local suppliers for incidental food service to

                              (E) with respect to concierge services, Alliance

                              (F) with respect to Financial Services, Alliance
shall be entitled to be a licensed broker, sales agent, associated person or
other licensed person for purposes of reoffering insurance or securities
brokerage services to Customers; provided, however, that if an RSI Entity is
then offering any such insurance or securities brokerage services, then, subject
to the other terms and conditions contained in this Section 2, Alliance shall
not reoffer to Customers any equivalent insurance or securities brokerage
services that are offered by a Third Party; and

                              (G) with respect to any particular RSI Reserved

Outsourced Product, if a Product Agreement has been entered into, (i) has not
been terminated by Alliance in accordance with the terms thereof (including,
without limitation, the dispute resolution procedures contained therein) as a
result of a breach by the RSI Entity in question, or (ii) provides as a remedy
for any breach thereof that RSI or the RSI Entity shall not be entitled to be
the exclusive supplier.

                        (iii) Except for courier services, the RSI Reserved
Outsourced Product shall be supplied on Most Favored Nation Terms.

                        (iv) The supply of the RSI Reserved Outsourced Product
shall be subject to the additional terms and conditions contained in Section 4
hereof.

                        (v) In the event of any Dispute regarding the
satisfaction of the RSI Reserved Outsourced Product Conditions or Most Favored
Nations Terms (if applicable), Alliance shall be prohibited from entering into
any agreement with a Third Party supplier for the supply of the RSI Reserved
Outsourced Product that is the subject of the Dispute until the earlier to occur
of (i) the expiration of the 45 day period commencing on the date that the Board
meeting relating to the resolution of such Dispute has been held, and (ii) the
final resolution of the Dispute in accordance with Section 3 hereof (if such
Dispute is finally resolved in favor of Alliance).

                        (vi) Nothing contained in this Agreement shall require
Alliance to terminate any agreement with any Third Party relating to the supply
of any product that is the same or similar Product as an RSI Reserved Outsourced
Product if the execution, delivery and performance of such agreement by Alliance
is not prohibited by this Agreement so long as the agreement with such Third
Party was entered into on customary and commercially reasonable terms.

                        (vii) Alliance shall keep RSI fully apprised on a
current basis of all of its current and planned needs for RSI Reserved
Outsourced Products, and shall notify RSI of its intention to enter into any
agreements with a Third Party for the provision of any RSI Reserved Outsourced
Product.

                  (b) Alliance shall keep RSI fully apprised on a current basis
of all of its current and planned General Outsourced Products and, in connection
therewith, shall promptly respond to RSI's reasonable inquiries related thereto.
An RSI Entity shall have the right, but not the obligation, to be a supplier to
Alliance of any General Outsourced Product for which the pricing and other terms
on which such RSI Entity is prepared to supply such General Outsourced Product
to Alliance, and the quality of such General Outsourced Product, satisfy the
General Outsourced Product Conditions, subject to the additional terms and
conditions contained in Section 4 hereof. During a period of 45 days commencing
on the earlier of (i) the date that an RSI Entity notifies Alliance in writing
that it desires to become a supplier of a specific General Outsourced Product,
or (ii) the date that Alliance notifies RSI in writing that it is seeking bids
from potential suppliers of a specific General Outsourced Product, such RSI
Entity and Alliance shall negotiate the pricing and other terms on which such
RSI Entity is prepared to supply such General Outsourced Product to Alliance,
and Alliance shall not enter into or renew any agreement with any Third Party
relating to the provision by such Third Party to Alliance of such General
Outsourced Product; provided, however, that Alliance shall not be prohibited
during such 45 day period from (x) entering into negotiations with a Third Party
with respect to the pricing and other terms on which such Third Party is
prepared to supply such General Outsourced Product to Alliance, or (y) procuring
such General Outsourced Product from a Third Party (who has the capacity and is
willing to deliver the General Outsourced Product in question and is reasonably
likely to provide the Product on the terms offered), whether pursuant to an
existing supply agreement or otherwise, if Alliance is then offering such
Product to its Customers. After the expiration of such 45 day period, Alliance
shall be entitled to enter into or renew an agreement with a Third Party (who
has the capacity and is willing to deliver the General Outsourced Product in
question and is reasonably likely to provide the Product on the terms offered)
for the supply of such General Outsourced Product, whether or not Alliance has
reached agreement with the RSI Entity for the supply of such General Outsourced
Product.

                  (c) If Alliance determines in its judgment (subject, in the
case of quality determinations, to the Reasonably Prudent Business Person
Standard) that the pricing and other terms on which an RSI Entity is prepared to
provide a General Outsourced Product or the quality of such Product do not
satisfy the General Outsourced Product Conditions, or that the pricing and other
terms on which an RSI Entity is prepared to provide an RSI Reserved Outsourced
Product or the quality of such Product do not satisfy the RSI Reserved
Outsourced Product Conditions or (if applicable) are not on Most Favored Nation
Terms, as the case may be, then Alliance shall promptly so notify RSI and
specify in reasonable detail the basis for such determination, including, if
applicable, identifying a bona fide Third Party supplier and its Product which
Alliance can obtain (and which such Third Party supplier has the capacity and is
willing to deliver the Product in question and is reasonably likely to provide
the Product on the terms offered) on more favorable pricing or other terms, or
with better quality, and a description of such more favorable pricing, other
terms or better quality. Such RSI Entity may then propose modifications to its
proposed provision of the Product and resubmit the Product proposal and, if such
RSI Entity and Alliance agree that such modified proposal would satisfy the
General Outsourced Product Conditions, or the RSI Reserved Outsourced Product
Conditions or Most Favored Nation Terms, as the case may be, then such RSI
Entity shall be a supplier for such Product in accordance with the terms hereof.
If the parties do not agree as to whether the General Outsourced Product
Conditions, or the RSI Reserved Outsourced Product Conditions or Most Favored
Nation Terms, as the case may be, are satisfied with respect to the Product,
then the provisions of Section 3 hereof shall be utilized to resolve such
Dispute.

                  (d) If an RSI Entity desires to supply to Alliance a Product,
other than a General Outsourced Product or an RSI Reserved Outsourced Product,
it shall notify Alliance and, thereafter, the parties shall enter into good
faith discussions with respect to the provision of such Product to Alliance. Any
such discussions shall include, without limitation, the terms and conditions on
which such RSI Entity would be willing to supply such Product to Alliance,
whether the anticipated financial and/or strategic benefits to Alliance from the
offer of such Product reasonably justifies such offer and whether such Product
is a Product that is generally sought in the marketplace by businesses.

                  (e) In the event of any termination of any Product Agreement,
whether pertaining to an RSI Reserved Outsourced Product or a General Outsourced
Product, in accordance with the terms thereof (including, without limitation,
the dispute resolution procedures contained therein) as a result of a breach by
the RSI Entity in question, then, no RSI Entity shall be entitled to be a
supplier to Alliance of the Product in question for the six-month period
commencing on the date of the termination of such Product Agreement. If Alliance
and an RSI Entity enter into a Product Agreement (a "Second Product Agreement")
with respect to any Product that was the subject of a Product Agreement that
previously was terminated by Alliance in the manner contemplated by the
immediately preceding sentence and the Second Product Agreement is terminated in
accordance with the terms thereof (including, without limitation, the dispute
resolution procedures contained therein) as a result of a breach by such RSI
Entity, then following termination of such Second Product Agreement (i) no RSI
Entity shall be entitled to be a supplier of the Product in question, and (ii)
if applicable, such Product shall no longer be an RSI Reserved Outsourced
Product for purposes of Section 5(a) hereof.

            3. Dispute Resolution.

                  (a) Any Dispute and the facts and circumstances related
thereto shall be presented to the Board. If a majority of the members of the
Board present and voting with respect to such Dispute shall agree with the RSI
Entity's position with respect to such Dispute, such determination shall be
final and binding on the parties. If less than a majority of the members of the
Board present and voting with respect to such Dispute agree with the RSI Entity
position with respect to such Dispute, then the parties shall submit such
Dispute, other than Disputes arising under Section 5, to binding arbitration in
accordance with Section 3(b) hereof. Notwithstanding anything to the contrary
contained herein, the Board shall not have the authority to award damages to any
party in connection with the resolution of any Dispute.

                  (b) Except for Disputes arising under Section 5, any (i)
Dispute which has not been resolved by the parties or by the Board and (ii) any
claim for breach of this Agreement and any damages related thereto shall be
settled by arbitration in accordance with the Expedited Procedures of the
Commercial Arbitration Rules of the American Arbitration Association (the "AAA")
then in effect except as modified below. The arbitration shall be held in New
York, New York. Any such Dispute or claim for breach shall be determined by a
panel of three arbitrators with each party to be provided a list of no less than
ten possible arbitrators and to be permitted no more than four strikes, and if
three arbitrators are not selected on the basis of the first list then provided,
another list of no less than ten possible arbitrators shall be provided for the
selection of any additional arbitrators needed, with each party again receiving
no more than four strikes, and this process shall continue until a full panel is
selected. The AAA shall be requested to include on its lists, to the extent it
finds reasonably possible, potential arbitrators with at least 5 years business
experience at a senior management level in outsourcing in the business services
sector or the closest equivalent experience. The decision of the arbitrators
shall be final and binding upon the parties. Judgment upon the award may be
entered in any court having jurisdiction. This Agreement and the rights and
obligations of the parties shall remain in full force and effect pending the
determination in any arbitration proceeding hereunder. The arbitrators shall (i)
award to the prevailing party, if any, all of its costs and fees, which shall
include all reasonable pre-determination expenses of the arbitration, including
the arbitrators' fees, administrative fees, travel expenses, out-of-pocket
expenses, court costs, and attorneys' fees and (ii) have the power to grant
injunctive relief.

                  (c) In the event that either party believes that any proposed
investment or business by any of the Persons subject to the restrictions set
forth in Section 5 would violate such restrictions, it shall so notify the other
party within six months after the date the party alleging such breach first
receives written notice from the other party of such investment or business. The
failure of a party to so notify the other party within such six-month period
shall constitute an irrevocable waiver by the party receiving notice of such
investment or business to contest such investment or business. Any Dispute
arising under Section 5 shall be resolved by a court of competent jurisdiction
located in the State of New York as set forth in Section 16 hereof.

                  (d) Except as provided in Section 3(c), the provisions of this
Section 3 shall be the exclusive means of resolving any controversy or claim
arising out of this Agreement or the transactions contemplated hereby.

            4. Terms and Conditions Regarding Provision of Products. The
provision of Products by an RSI Entity to Alliance and the offer of such
Products by Alliance to the Customers shall in all cases be subject to the
following additional terms and conditions:

Entity (whether a General Outsourced Product or an RSI Reserved Outsourced

execution plan for the sales, marketing and distribution of such Product to its
Customers, including the advertising and promotion of such Product to the
Customers, the timing of commencement of offering the Product and how it is
rolled out (e.g. distributed and marketed) through Alliance's executive office
suite centers, the pricing of the Product to Customers, and the content of any
marketing or advertising materials relating to the Product (it being agreed and
understood that in no event shall Alliance delay the production of an execution
plan for purposes of delaying the offering of any General Outsourced Product or
RSI Reserved Outsourced Product). In devising such execution plan, Alliance
shall consult with the RSI Entity that will be supplying such Product. All sales
of the Product by the RSI Entity shall be made in accordance with the execution
plan. If, with respect to any Product, Alliance advises the RSI Entity that
Alliance does not desire to control the marketing of the Product to the
Customers by means of an execution plan, the RSI Entity shall be entitled to
directly market such Product to the Customers and Alliance shall cooperate with
such RSI Entity's reasonable requests in connection therewith. In its marketing
efforts to its Customers, Alliance shall (i) use commercially reasonable efforts
to endorse and promote the Products that are the subject of any Product
Agreement, and will cooperate with the RSI Entity in co-marketing efforts,
solicitation of Customers, and providing to RSI marketing data (including the
identity of Customers) relevant to the Product in question, and (ii) subject to
clause (i) of this sentence, in the case of the same or substantially similar
Products that are supplied to Alliance by an RSI Entity and any other Third
Party supplier, Alliance shall endorse and promote the RSI Entity Product to the
same extent (or, in Alliance's sole discretion, to a greater extent) as it
endorses and promotes the Product of such Third Party supplier.

                  (b) Alliance and an RSI Entity shall enter into a mutually
satisfactory Product Agreement for the provision of each Product which such RSI
Entity will provide to Alliance pursuant to this Agreement. Each Product
Agreement shall contain the provisions set forth in Exhibit 1 hereto, as well as
such additional terms and conditions as the parties may negotiate. If, pending
the execution of any such Product Agreement, either such RSI Entity or Alliance
employs any printed form of purchase order or order confirmation with respect to
such Product, unless otherwise agreed by the parties in writing, the printed
terms and conditions thereof will not apply to the purchase and sale of any
Product during the term of this Agreement to the extent that any such term or
condition is in conflict with a provision of this Agreement.

                  (c) If (i) Alliance and an RSI Entity have agreed in any
Product Agreement that such RSI Entity shall be the exclusive supplier of any
Product (whether pursuant to Section 2(a) or otherwise) or (ii) any Product
provided by an RSI Entity to Alliance accounts for 75% or more of Alliance's
gross revenues from such Product in any trailing six month period, then the
Product Agreement relating to the Product in question (whether the initial
Product Agreement for a Product or, in the event that the test specified in
clause (ii) of this paragraph has been met, in the renewal or new Product
Agreement entered into after such test has been met) shall provide for Most
Favored Nation Terms. In connection with the execution or renewal of any Product
Agreement, the RSI Entities shall keep Alliance apprised of the terms and
conditions pursuant to which such RSI Entities are offering to any Third Party
the Product that is the subject of the Product Agreement and, in connection
therewith, shall promptly respond to Alliance's reasonable inquiries related
thereto.

                  (d) The RSI Entity in question shall be entitled to supply the
Product in question during the term of the Product Agreement, subject, in each
case, to the termination provisions contained therein. Without limiting the
provisions of Section 4(e) hereof and subject to the right of Alliance to
terminate any Product Agreement in accordance with the terms thereof, nothing
contained in this Agreement shall require any RSI Entity to modify the terms or
conditions of any Product Agreement during the term thereof in the event that
the General Outsourced Product Conditions or the RSI Reserved Outsourced Product
Conditions, as the case may be, shall fail to continue to be satisfied or in the
event that such terms or conditions are no longer Most Favored Nations Terms.
Alliance and RSI acknowledge and agree that for purposes of this Agreement (and
without limiting the provisions of any Product Agreement) the General Outsourced
Product Conditions, the RSI Reserved Outsourced Product Conditions and Most
Favored Nation Terms shall be measured only at the time of each initial
determination as to whether an RSI Entity shall be entitled to supply a Product
to Alliance and at the time of the expiration of any Product Agreement or during
any negotiations with respect to the renewal thereof.

                  (e) If, at the time of expiration of any Product Agreement or
at the time of negotiations with respect to the renewal thereof, Alliance
determines in its judgment (subject in the case of quality determinations, to
the Reasonably Prudent Business Person Standard) that the General Outsourced
Product Conditions, the RSI Reserved Outsourced Product Conditions, or Most
Favored Nation Terms, as the case may be, are not then met with respect to any
Product, then Alliance shall so notify the applicable RSI Entity and specify in
reasonable detail the basis for such determination, including, if applicable,
identifying a bona fide Third Party supplier and its Product which Alliance can
obtain (and which such Third Party supplier has the capacity and is willing to
deliver the Product in question and is reasonably likely to provide the Product
on the terms offered) on more favorable terms or conditions or with better
quality and a description of such more favorable pricing, other terms and better
quality. The RSI Entity may then propose modifications to its provision of the
Product in a manner that such RSI Entity and Alliance agree would result in the
satisfaction of the General Outsourced Product Conditions, the RSI Reserved
Outsourced Product Conditions, or Most Favored Nation Terms, as the case may be.
If the parties still do not agree as to whether the General Outsourced Product
Conditions, the RSI Reserved Outsourced Product Conditions, or Most Favored
Nation Terms, as the case may be, are satisfied with respect to the Product,
then the provisions of Section 3 hereof shall be utilized to resolve such
Dispute.

            5. Non-Competition.

                  (a) Alliance shall not, and shall cause its Controlled
Affiliates not to, directly or indirectly, (i) engage in the business of, or act
as a manager, managing member, general partner, director, officer, employee of
or consultant to any Person directly or indirectly engaged in the business of,
offering any RSI Reserved Outsourced Product other than through an RSI Entity
or, solely to the extent permitted pursuant to Section 2(a) hereof, a Third
Party, or (ii) knowingly own or control any voting securities or other
securities convertible into voting securities, interest in any Person that
offers any RSI Reserved Outsourced Product. Notwithstanding the foregoing,
Alliance and its Affiliates shall be permitted to make an investment in any
Person that offers any RSI Reserved Outsourced Product provided that within 9
months after the consummation of the investment, such Person ceases to offer any
RSI Reserved Outsourced Products. If such Person ceases to offer such RSI
Reserved Outsourced Products through the divestiture of any business lines,
Alliance shall use, and shall cause each of its Controlled Affiliates to use,
its reasonable good faith efforts to cause such Person to offer RSI the first
opportunity to acquire such business lines. The prohibitions set forth in this
Section 5(a) shall not apply to any existing or future investments made by
Cahill, Warnock Strategic Partners Fund, L.P., Strategic Associates, L.P.,
Cahill, Warnock & Company, LLC, Northwood Ventures LLC, Northwood Capital
Partners LLC, Paribas, any investment entity that is an Affiliate of any such
Persons, or to any other Non-Controlled Affiliate of Alliance. RSI shall be
entitled to injunctive relief as a remedy for any breach of the provisions of
this Section 5(a). Such remedy shall not be deemed to be the exclusive remedy in
the event of any such breach, but shall be in addition to all other remedies
that may be available to RSI at law or in equity.

                  (b) RSI shall not, and shall (x) cause each of its Controlled
Affiliates and (y) use reasonable good faith efforts to cause the Reckson
Affiliates, not to, directly or indirectly, (i) "Compete" with Alliance, or act
as a manager, managing member, general partner, director, officer, consultant
to, or as an employee of, any Person that directly or indirectly Competes with
Alliance, or (ii) knowingly own or control any voting securities or other
securities convertible into voting securities in any Person that Competes with
Alliance. A Person shall be deemed to "Compete" with Alliance, for purposes of
this Section 5(b), if a business conducted by such Person is materially
competitive with the Alliance Business. In determining whether a business
conducted by a Person is materially competitive with the Alliance Business, the
factors to be considered shall include, without limitation, the respective
customer base and distribution channels of such Person and the Alliance Business
with respect to the specific Products which compete with each other.
Notwithstanding the foregoing, a Person shall not be deemed to Compete with
Alliance if it offers for sale one or more Products which are part of the
Alliance Business so long as the provision of any such Products taken in the
aggregate are not materially competitive with the Alliance Business.

            Notwithstanding the foregoing, each of RSI, its Affiliates and the
Reckson Affiliates shall be permitted to make an investment in any Person whose
business Competes with Alliance, provided that within 9 months after the
consummation of such investment, such Person ceases to engage in the business
which Competes with Alliance provided, that if there is a Dispute with respect
to whether an investment Competes, then any required divestiture shall not be
required until nine (9) months after the date of final determination of such
Dispute adverse to RSI or any RSI Entity. If such Person ceases to engage in the
business which Competes with Alliance through the divestiture of the competing
business lines (including any divestiture following a final determination
described below), RSI shall (i) use and cause each of its Controlled Affiliates
to use and (ii) use reasonable good faith efforts to cause the Reckson
Affiliates to use, its reasonable good faith efforts to cause such Person to
offer Alliance the first opportunity to acquire such business lines which it is
divesting.

            Nothing in this Section 5(b) shall limit the right of any of RSI,
its Affiliates or the Reckson Affiliates to (i) offer any RSI Reserved
Outsourced Product, or (ii) own not more than 4.9% of the outstanding shares of
a corporation or other entity whose shares or other equity or debt interests are
listed on any United States national or regional securities exchange or reported
by NASDAQ or any successor thereto. The prohibitions set forth in this Section
5(b) shall not apply to a Person if such Person is both a Non-Controlled
Affiliate of RSI and is not a Reckson Affiliate. In the event of a final
determination by a court of competent jurisdiction that any of RSI, its
Controlled Affiliates or the Reckson Affiliates has breached the covenants in
this Section 5(b), then in addition to Alliance's right to recover the profits
(taking into account the consideration set forth in the last sentence of this
paragraph) to RSI and its Affiliates derived from the operations of the business
or investment that has been determined to Compete with Alliance for the period
commencing on the notification of a Dispute with respect to such business or
investment pursuant to Section 3(c) hereof and ending on the earlier to occur of
(i) the date of divestiture of the business line that Competes with Alliance or
(ii) the date of termination of this Agreement pursuant to this Section 5 (which
right to recover such profits (taking into account the consideration set forth
in the last sentence of this paragraph) shall be Alliance's sole and exclusive
remedy at law and in equity for such breach other than Alliance's right to
terminate this Agreement pursuant to this Section 5(b) and other than Alliance's
rights under the Stockholders' Agreement, dated as of _______, 1998, by and
among Alliance and certain of its Securityholders), this Agreement shall
automatically terminate on the 30th day following the final determination that
there has been a breach of this Section 5(b), provided, however, that this
Agreement shall not terminate if, during such 30-day period, RSI at its option,
delivers written notice to Alliance that the business line which Competes with
Alliance will be divested, and such divestiture is actually completed within
nine months after the date of such final determination. If a breach of the
covenant contained in this Section 5(b) arises out of an investment in an entity
that is not a wholly owned subsidiary of RSI or its Affiliates (an "Acquired
Competing Party"), then, for purposes of the immediately preceding sentence, the
profits referred to therein shall include only those profits that RSI or its
Affiliates (other than the Acquired Competing Party and its Controlled
Affiliates) shall have received and the portion of the profits of the Acquired
Competing Party as to which RSI or its Affiliates (other than the Acquired
Competing Party and its Controlled Affiliates) would be entitled by virtue of
their proportionate ownership in the Acquired Competing Party (whether or not
such profits have been distributed to RSI or its Affiliates).

            It is acknowledged and agreed that no provision of this Section 5(b)
shall require RSI, its Controlled Affiliates or any RSI Entity to divest or
refrain from conducting any investment or business (a "Pre-Existing Business")
which it acquired or developed prior to the time that, as a result of
developments of or modifications to the Alliance Business, such Pre-Existing
Business taken as a whole Competes with Alliance. However, the restrictions set
forth in Section 5(b) shall apply to such Pre-Existing Business if, as a result
of developments of or modifications to such Pre-Existing Business, such
Pre-Existing Business taken as a whole then Competes with Alliance.

            6. Term. Subject to earlier termination as provided in Section 7
hereof, the term of this Agreement shall commence on the date of this Agreement
and shall continue for a period of five (5) years thereafter. This Agreement
shall automatically be extended for an additional five (5) year term if, upon
expiration of the initial term referred to in the immediately preceding
sentence, RSI and its Controlled Affiliates "beneficially own" (as such term is
defined in Rule 13d-3 promulgated under the Exchange Act), in the aggregate, at
least 15% of the Adjusted Fully Diluted Capitalization. Except as may be
provided in any Product Agreement, any termination of this Agreement shall not
affect any Product Agreement then in effect, including, without limitation, any
provisions contained in such Product Agreement that may be incorporated by
reference from this Agreement.

            7. Termination. This Agreement may be terminated at any time:

                  (a) by the mutual written consent of Alliance and RSI;

                  (b) by Alliance, pursuant to Section 5(b);

                  (c) by Alliance, in the event that RSI and its Controlled
Affiliates fail to continue to "beneficially own," in the aggregate, at least
15% of the Adjusted Fully Diluted Capitalization; or

                  (d) by Alliance, in the event that any of (w) CarrAmerica, (x)
HQ Omni, or (y) Regus, so long as any of such Persons named in clauses (w), (x)
or (y) are then engaged in the executive suite business, or (z) any other Person
which owns or operates 50 or more executive office suite centers as its primary
business (any of the foregoing persons, a "Disqualified Transferee") acquires
Control of RSI (provided that for this purpose no presumption of Control shall
arise solely from ownership of any specific percentage of equity securities of
RSI); unless prior to or substantially contemporaneously with such acquisition,
beneficial ownership of the equity securities of Alliance held by RSI shall have
been transferred to a Person that is (1) Controlled by the executive officers of
RSI immediately prior to such acquisition and (2) not an Affiliate of RSI or the
Disqualified Transferee following such acquisition.

            8. Effect on Subsidiaries of Alliance. As used herein, the term
"Alliance" shall mean Alliance and each of its Subsidiaries. Alliance shall
cause each of such Subsidiaries, as applicable under the circumstances, to abide
by the provisions contained in this Agreement as if such Subsidiary were a party
hereto.

            9. Notices. All notices, requests, demands, acceptances and other
communications which are required or permitted under this Agreement shall be in
writing and shall be deemed to have been duly given (a) when delivered
personally, or (b) when sent by fax if sent on a business day prior to 5:00 P.M.
local time at the place of receipt, or on the following business day if sent
after 5:00 P.M. or on a non-business day, or (c) on the day following delivery

notice to the other, (a) extend the time for the performance of any of the
obligations or other actions of the other, (b) waive compliance with any of the
terms, conditions or covenants required to be complied with by the other
hereunder; and (c) waive or modify performance of any of the obligations of the
other hereunder. The waiver by any party hereto of a breach of any provision of
this Agreement shall not operate or be construed as a waiver of any other or
subsequent breach.

            11. Entire Agreement. This Agreement (together with any Product
Agreement with respect to a specific Product) constitutes the entire agreement
between the parties with respect to the subject matter hereof. No provision
hereof may be amended or modified except in writing, executed by all parties
hereto against which enforcement of such modification or amendment is sought.

            12. Binding Effect; Benefits. This Agreement shall inure to the
benefit of and be binding upon the parties hereto and their respective permitted
successors and assigns. Except as set forth in the following provisions of this
Section 12, nothing in this Agreement, express or implied, is intended to confer
on any person other than the parties hereto and the other RSI Entities or their
respective permitted successors and assigns, any rights, remedies, obligations
or liabilities. Subject to the terms and conditions of this Agreement, OnSite
shall be the exclusive supplier with respect to the provision to Alliance of

a third party beneficiary of this Agreement.

            13. Assignment. Neither this Agreement nor any of the rights,
interests or obligations hereunder shall be assigned or delegated by any party
hereto (whether by operation of law or otherwise) without the prior written
consent of the other party; provided, however, that RSI may assign its rights
and interest hereunder without the prior written consent of Alliance to any
Subsidiary or, if applicable, to any parent company of RSI, or to a Person
which, by reason of merger, consolidation, sale of stock or sale of assets,
succeeds to substantially all of the business of RSI. No such assignment shall
relieve RSI of any of its obligations hereunder.

            14. Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable.

            15. Governing Law. The interpretation and performance of this
Agreement shall be governed by and construed in accordance with the laws of the
State of New York without regard to such State's conflicts of laws principles.

            16. Jurisdiction. SUBJECT TO THE AGREEMENT OF THE PARTIES TO
ARBITRATE AS SET FORTH IN SECTION 3 HEREOF, EACH PARTY TO THIS AGREEMENT HEREBY
IRREVOCABLY AGREES THAT THE ANY LEGAL ACTION OR PROCEEDING ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (INCLUDING,
WITHOUT LIMITATION, ANY ACTION TO ENFORCE THE AWARD PURSUANT TO AN ARBITRATION
AS PROVIDED BY SECTION 3 HEREOF) MAY BE BROUGHT IN THE COURTS OF THE STATE OF
NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW
YORK AND HEREBY EXPRESSLY SUBMITS TO THE PERSONAL JURISDICTION AND VENUE OF SUCH
COURTS FOR THE PURPOSES THEREOF AND EXPRESSLY WAIVES ANY CLAIM OF IMPROPER VENUE
AND ANY CLAIM THAT SUCH COURTS ARE AN INCONVENIENT FORUM. EACH PARTY HEREBY
IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED
COURTS IN ANY SUCH SUIT, ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF
BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO ITS ADDRESS SET FORTH IN
SECTION 9, SUCH SERVICE TO BECOME EFFECTIVE 10 DAYS AFTER SUCH MAILING.

            17. Confidentiality. (a) All Confidential Information furnished by a
party to the other party pursuant hereto shall be treated as the sole property
of the furnishing party and each party receiving information shall promptly
return (and in any event no later than 10 business days after any request) to
the furnishing party all of such written information and all documents, notes,
summaries or other materials containing, reflecting or referring to, or derived
from, such information. Each party receiving Confidential Information shall keep
confidential all such information, and shall not directly or indirectly use such
information for any competitive or other commercial purpose, other than as
specifically contemplated by this Agreement.

                  (b) The obligation to keep Confidential information as such
shall not apply to (i) any information which (A) was already in the receiving
party's possession on a non-confidential basis prior to the disclosure thereof
by the furnishing party; (B) was then generally known to the public other than
as a result of disclosure by the receiving party in violation of the provisions
hereof; or (C) was disclosed to the receiving party by a third party not bound
by any obligation of confidentiality or (ii) disclosures made as required by
law. If the receiving party is requested or required (by oral question or
request for information or documents in legal proceedings, interrogatories,
subpoena, civil investigative demand or similar process) to disclose any
information concerning the receiving party, the receiving party will promptly
notify the furnishing party of such request or requirement so that the
furnishing party may seek an appropriate protective order and/or waive the
receiving party's compliance with the provisions or this Agreement. It is
further agreed that, if in the absence of a protective order or the receipt of a
waiver hereunder the receiving party is nonetheless, in the opinion of its
counsel, compelled to disclose information concerning the furnishing party to
any tribunal or governmental body or agency or else stand liable for contempt or
suffer other censure or penalty, the receiving party may disclose such
information to such tribunal or governmental body or agency to the extent
necessary to comply with such order as advised by counsel without liability
hereunder.

                  (c) Without limiting the foregoing, no receiving party shall
disclose any Confidential Information other than to senior officers of such
party who need to know such information. In the event any furnishing party is
required to provide any Confidential Information, such party will be deemed to
have satisfied its obligations by making such information available at its
principal executive offices during reasonable business hours. No receiving party
shall make any copies of any Confidential Information without the furnishing
party's written consent, which consent shall not be unreasonably withheld or
delayed.

                  (d) Each receiving party understands and agrees that the
furnishing party will suffer immediate, irreparable harm in the event such
receiving party fails to comply with any of its obligations of confidentiality
under this Agreement, that monetary damages will be inadequate to compensate the
furnishing party for such breach and that such furnishing party shall be
entitled to specific performance as a remedy for any such breach. Such remedy
shall not be deemed to be the exclusive remedy in the event of breach of this
Agreement by any receiving party, but shall be in addition to all other remedies
available to the furnishing party at law or in equity.

            18. Headings. Headings of the Sections in this Agreement are for
reference purposes only and shall not be deemed to have any substantive effect.

            19. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed an original, but all of which
together shall be deemed to be one and the same instrument.

            20. Facsimile Signatures. This Agreement may be signed by facsimile
copy and shall be valid and binding upon delivery of a signed copy by facsimile.

Agreements (as hereinafter defined).

                              W I T N E S S E T H :

            WHEREAS, each Employee is party to an agreement dated as of October
29, 1999 (collectively, the "Exchange Agreements" and each individually, an
"Exchange Agreement") with VANTAS and RSI; and

            WHEREAS, the parties to the Exchange Agreements desire enter into
this Agreement to resolve certain disagreements which have arisen under the
Exchange Agreements upon the terms and conditions set forth below;

            NOW, THEREFORE, in consideration of the premises and the covenants,
agreements and undertakings contained in this Agreement, and other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto agree as follows:

            1. Amount of Additional Compensation. The aggregate amount of the
Additional Compensation for all purposes of the Exchange Agreements is Ten
Million Eight Hundred Eighty-One Thousand Nine Hundred and Nine Dollars
($10,881,909.00). At the Exchange Closing, the Employees, in lieu of receiving
the checks contemplated by the last sentence of Section 2(b) of their Exchange
Agreements, shall, subject to the proviso contained in Section 3(a) and the
provisions of Section 3(c) of their Exchange Agreements, have withheld the
applicable taxes which need to be paid in connection with the Exchange Closing,
which amount for all Employees is acknowledged by the Employees to be Ten
Million Eight Hundred Eighty-One Thousand Nine Hundred and Nine Dollars
($10,881,909.00). Such amount shall be allocated to the Employees in the amount
set forth opposite their names (the "Employee's Tax Share") on Schedule I
attached hereto. With respect to each Employee, any tax liabilities of any kind
in connection with the Exchange Closing which exceed such Employee's Tax Share
shall be the sole responsibility of such Employee. Each of the Employees hereby
covenants and agrees to indemnify and hold harmless each of VANTAS and RSI from
and against any tax liability (including, without limitation, interest,
penalties and reasonable attorneys' fees and disbursements related thereto)
incurred by VANTAS or RSI or their respective affiliates relating to (i) the
Exchange Closing in excess of his or her Employee's Tax Share and (ii) any loans
made by VANTAS under the Program.

            2. Exchange Closing Deliveries. The Exchange Closing shall be held
at the offices of Herrick, Feinstein LLP, 2 Park Avenue, New York, New York at
11:00 a.m., (New York City time) on December 30, 1999. At the Exchange Closing,
each Employee shall deliver to RSI that number of Exchange Securities set forth
opposite his or her name on Schedule II attached hereto in exchange for that
number of RSI Shares set forth opposite his or her name on Schedule II attached
hereto. All Exchange Securities delivered by the Employees at the Exchange
Closing shall be Option Shares.

            3. Remaining Exchange Closing. Notwithstanding anything to the
contrary contained in the Exchange Agreements, with respect to the balance of
each Employee's VANTAS securities not delivered to RSI at the Exchange Closing,
which balances are set forth opposite such Employee's name on Schedule III
attached hereto (the "Remaining Closing Securities"), each Employee shall
exchange at the Remaining Exchange Closing (as hereinafter defined) his or her
Remaining Closing Securities for the number of RSI Shares not delivered at the
Exchange Closing (the "Remaining RSI Shares") in the amounts set forth opposite
his or her name on Schedule III attached hereto. The closing for such exchange
("Remaining Exchange Closing") shall be held at the offices of Herrick,
Feinstein LLP, 2 Park Avenue, New York, New York at the earlier of five (5)
business days of receipt by RSI of a written notice to close issued by all of
the Employees who have not yet engaged in a Remaining Exchange Closing (which
written notice shall in no event be delivered prior to January 1, 2000 nor later
than June 30, 2000) or five (5) business days after June 30, 2000 in which event
RSI will close with all Employees who have delivered notice to close and with
such other Employees as RSI shall determine; provided, however, that if at any
time during the period commencing on January 1, 2000 and terminating on June 30,
2000, any of four (4) or more of the Employees shall have delivered written
notice to RSI to close with such Employees, then RSI shall engage in a Remaining
Exchange Closing with such Employees no later than five (5) business days after
receipt of such notice. In the event that any Employee shall fail to engage in a
Remaining Exchange Closing by June 30, 2000, RSI shall have the right, but not
the obligation, upon five (5) business days' written notice to the Employee, to
require the Employee to make arrangements to pay the requisite taxes and to
exchange his or her Remaining Closing Securities for the Remaining RSI Shares
or, in the alternative, at any time after June 30, 2000, declare the Exchange
Agreement for such Employee and this Agreement as it relates to such Employee to
be deemed to have been fully performed on the part of VANTAS and RSI for all
purposes. Notwithstanding anything to the contrary contained in the Exchange
Agreements, the Remaining Closing Securities do not need to be Option Shares and
shall consist of Employee Securities selected by the Employee in his or her sole
discretion. Each Employee hereby covenants and agrees that, at or prior to the
effective time of his or her Remaining Exchange Closing, he or she shall have
paid the total dollar amount of the tax liability associated with his or her
exchange of Remaining Closing Securities for Remaining RSI Shares; provided,
however, that such obligation shall not extend to any capital gains tax
liability personal to such Employee and which the Employee covenants to pay when
due. RSI shall have no obligation to exchange the Remaining RSI Shares for the
Remaining Closing Securities of any Employee, unless such Employee shall have
made the payment contemplated by the immediately preceding sentence. Each of the
Employees hereby covenants and agrees to indemnify and hold harmless each of
VANTAS and RSI from and against any tax liability (including, without
limitation, interest, penalties and reasonable attorneys' fees and disbursements
related thereto) incurred by VANTAS or RSI or their respective affiliates
relating to the exchange of his or her Remaining Closing Securities for
Remaining RSI Shares.

            4. Remaining Exchange Closing Procedures. At each Remaining Exchange
Closing, (i) RSI shall deliver to the Employee participating therein the stock
certificates evidencing the Remaining RSI Shares registered in the name of such
Employee and (ii) the Employee participating therein shall deliver to RSI the
stock certificate(s) evidencing the Remaining Closing Securities, duly endorsed
in blank or accompanied by stock powers duly executed in blank in proper form
for transfer and with all required stock transfer stamps attached, free and
clear of any title defect, objection, security interest, pledge, encumbrance,
mortgage, lien, charge, claim, option, preferential arrangement or restriction
of any kind, including, but not limited to, any restriction on the use, voting,
transfer, receipt of income or other exercise of any attributes of ownership
(collectively, "Liens"), other than those Liens, if any, existing under the
Stockholders' Agreement.

            5. Non-Applicability of Preemptive Right. Each of the Employees
hereby irrevocably acknowledges and agrees that the preemptive right provisions
contained in Section 7.1 of the Stockholders' Agreement do not apply to the
financing transaction VANTAS will engage in to raise the Additional Compensation
amount covered by Section 1 hereof.

            6. Miscellaneous.

            (a) Each of the parties hereto hereby acknowledges and agrees that
the usage of the term "Exchange Closing" herein and in the Exchange Agreements
shall mean the closing referenced in Section 2 hereof as the "Exchange Closing"
occurring on December 30, 1999 and not the Remaining Exchange Closing.
Accordingly, and without limitation, the provisions contained in Sections 2(d)
and 2(f) of the Exchange Agreement to which David W. Beale is a signatory shall
become effective and otherwise operative immediately upon consummation of the
Exchange Closing. This Agreement and the Exchange Agreements contain, and are
intended as, a complete statement of all of the terms of the arrangements and
understandings among the parties with respect to the matters provided for herein
and therein, and supersede any previous agreements and understandings among the
parties with respect to those matters. No Employee has relied on any statement,
promise or understanding not expressly set forth in this Agreement, the Exchange
Agreements or the VANTAS Incorporated Employee Loan Plan. Except as expressly
modified by this Agreement, all of the terms and conditions of the Exchange
Agreement shall remain in full force and effect. As a result of this Agreement,
all parties hereto irrevocably acknowledge and agree that each Exchange
Agreement is being fully and duly performed in accordance with all of its terms
and conditions. In the event of any inconsistency between the terms of this
Agreement and the Exchange Agreements, this Agreement shall prevail.

            (b) This Agreement shall be governed by, and construed and enforced
in accordance with the laws of the State of New York without regard to its
principles of conflicts of law. All actions and proceedings arising out of, or
relating to, this Agreement shall be heard and determined in any state or
federal court sitting in New York, New York. In the event of any dispute as to
the terms of this Agreement, the prevailing party in any litigation or other
proceeding shall be entitled to its reasonable attorneys' fees, costs and
expenses in connection therewith.

            (c) All notices and other communications under this Agreement shall
be in writing and shall be hand delivered, mailed by registered or certified
mail, return receipt requested (with a copy simultaneously by ordinary mail), or
recognized overnight delivery service to the parties in the manner and with the
effect provided for in the Exchange Agreements.

            (d) No provision of this Agreement may be amended or modified except
by an instrument or instruments in writing signed by the parties hereto. The
failure of a party at any time or times to require performance of any provision
hereof shall in no manner be deemed to affect the party's right at a later time
to enforce the same. No waiver by any party of the breach of any term contained
in this Agreement, whether by conduct or otherwise, in any one or more
instances, shall be deemed to be or construed as a further or continuing waiver
of any such breach or of the breach of any other term or provision of this
Agreement.

            (e) This Agreement shall be binding on, and shall inure to the
benefit of, the parties hereto and their respective successors and permitted
assigns. The rights and obligations of any party hereto may not be assigned or
transferred without the prior written consent of the other parties hereto.

            (f) From and after the date hereof, each of the parties hereto
agrees to execute and deliver such further documents and instruments and to do
such other acts and things any of them, as the case may be, may reasonably
request in order to effectuate the transactions contemplated by this Agreement.

            (g) Any word or term used in this Agreement in any form shall be
masculine, feminine, neuter, singular or plural, as proper reading requires.

            (h) Time shall be of the essence with respect to all notices
required to be given, all payments and other deliveries required to be made and
all conditions required to be satisfied under this Agreement.

            (i) The obligations of the Employees hereunder are not joint but
rather are several as to themselves.

            IN WITNESS WHEREOF, the parties hereto have executed and delivered,
or caused the execution and delivery of, this Agreement on the date first
written above.
