Item 5.           Other Events.

         Reckson  Service  Industries,  Inc.  ("RSI"  or  the  "Company")  and a
wholly-owned  subsidiary  have  entered  into a stock  purchase  agreement  (the
"Agreement")  with  Cahill,  Warnock  Strategic  Partners  Fund L.P.,  Strategic
Associates, L.P., and David L. Warnock (collectively, the "Sellers") to purchase
all of the 4,694,560  shares of Series A Convertible  Preferred  Stock,  626,202
shares of the Series B  Convertible  Preferred  Stock and 704,184  warrants  and
15,000  options  to  purchase  Class  A  Common  Stock  of  VANTAS  Incorporated
("VANTAS")  owned  by  the  Sellers  (the  "Shares").  In  connection  with  the
Agreement, the two director nominees of the Sellers on the Board of Directors of
VANTAS (the  "Board") were  replaced  with  individuals  designated by RSI. As a
result,  RSI  increased  its  representation  on the  Board  to  six  out of ten
directors.

         VANTAS is the largest  owner of executive  office  suites in the United
States, with 190 suites.

         Subject to certain adjustments contained in the Agreement, the purchase
price for each transferred share is (i) $5.60 in cash and (ii) 0.1263 of a share
of common stock, par value $0.01 per share ("RSI Common Stock"), of the Company.
The Sellers will also receive  registration  rights in respect of the RSI Common
Stock.

         The Sellers had previously  entered into a stockholders  agreement with
certain other holders of VANTAS securities (the "Tag Along Holders") under which
the Tag Along  Holders have (i) a right of first  refusal to acquire the Shares,
which right lapses on October 14, 1999 and (ii) "tag along" rights to sell their
VANTAS  securities  together  with,  and  generally  on the same  terms as,  the
Sellers.  The Company has  agreements in principle with certain of the Tag Along
Holders  (the   "Significant  Tag  Along  Holders"),   pursuant  to  which  such
Significant  Tag Along  Holders  will waive  their  rights of first  refusal and
exercise  their tag along  rights.  Under  certain  circumstances,  the  Sellers
receiving  RSI common  stock have the right to  receive  an  additional  payment
during the 13th month  subsequent  to the closing of the  transaction,  provided
that such right ceases to exist if the closing price of RSI common stock for any
consecutive 15 days is $19.00 per share or higher.

         It is  estimated  that  upon  consummation  of  the  transaction  RSI's
ownership will increase from approximately 35% to between  approximately 77% and
95%,  depending upon whether the Tag Along Holders exercise their rights to sell
their shares.  RSI's  additional  investment will range from $82 million of cash
and 2.0  million  shares of RSI  common  stock to $121  million  of cash and 3.0
million shares of RSI common stock,  depending on the level of  participation of
the Tag Along Holders.

         RSI,  through a  subsidiary,  has also  entered  into an  agreement  to
purchase an entity which indirectly owns shares of VANTAS,  membership interests
in OnSite Commerce and Content LLC ("OnSite  Commerce") and OnSite Access,  Inc.
("OnSite  Access")  from  certain  affiliates  of Jon L. Halpern in exchange for
2,452,570 shares of RSI Common Stock,  $15,129,272 in cash and a promissory note
in the amount of $5,307,200 payable on or before December 30, 1999.

         The  purchase  of the  shares  of OnSite  Access  will  increase  RSI's
ownership to approximately  42% and the purchase of the membership  interests of
OnSite Commerce increased RSI's ownership in OnSite Commerce to 100%. The shares
of VANTAS  owned by the  affiliate  of Mr.  Halpern  are  included  in the above
description of the Significant Tag Along Holders.

         OnSite Access is a building-centric  integrated communications provider
supplying high speed Internet access, digital voice, broadband data and enhanced
communications  services to the tenants of commercial office  buildings.  OnSite
Commerce  is a company  through  which RSI will seek to develop a portal for the
delivery of  Internet-based  business to business  outsourced  business services
offered by RSI or its partner companies.

                                   AGREEMENT


          AGREEMENT, dated as of August 19, 1999 (this "Agreement"), by and
among RECKSON SERVICE INDUSTRIES, INC., a Delaware corporation ("RSI"), RSI
I/O HOLDINGS, INC., a Delaware corporation (together with its affiliates, the
"Buyer"), and CAHILL, WARNOCK STRATEGIC PARTNERS FUND L.P., a Delaware limited
partnership ("CW"), STRATEGIC ASSOCIATES, L.P., a Delaware limited partnership
("SA"), and DAVID L. WARNOCK, an individual ("DW"; and together with CW and
SA, the "Sellers").

                                   RECITALS

          WHEREAS, each of the Sellers is the record and beneficial owner of
the number of Series A Convertible Preferred Stock, par value $0.01 per share
("Series A Stock"), Series B Convertible Preferred Stock, par value $0.01 per
share ("Series B Stock"), warrants ("Warrants") to purchase Class A Common
Stock, par value $0.01 per share ("Class A Common Stock"), and options
("Options") to purchase Class A Common Stock, of VANTAS Incorporated, a Nevada
corporation, f/k/a/ALLIANCE National Incorporated (the "Company"), set forth
opposite their respective name on Schedule A annexed hereto; and

          WHEREAS, a bona fide offer (a copy of which is attached hereto as
Exhibit A; the "Offer Notice") has been made by the Buyer to the Sellers to
purchase all of the Series A Stock, the Series B Stock, the Warrants and the
Options owned by each of the Sellers (collectively, the "Transferred Shares"),
and each of the Sellers desires to sell to the Buyer, and the Buyer desires to
purchase from each of the Sellers, the Transferred Shares, upon the terms and
subject to the conditions set forth herein;

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

                                  ARTICLE I
                               PURCHASE AND SALE

          SECTION 1.1 Purchase and Sale of the Transferred Shares. Upon the
terms and subject to the conditions set forth in this Agreement, the Buyer has
offered to purchase from the Sellers at the Closing (as defined below), the
Transferred Shares, 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 expressly created by the Fifth Amended and Restated
Stockholders' Agreement dated as of July 29, 1999 (the "Stockholders'
Agreement") by and among the Company and the Securityholders identified
therein, and the Sellers have agreed to accept such offer as provided in this
Agreement.

          SECTION 1.2 Purchase Price; Deposit; Exercise of Options and
Warrants.

          (a) The purchase price (the "Purchase Price") for each Transferred
Share shall be: (i) Five Dollars and sixty cents ($5.60) in cash and (ii)
0.1263 of a share (the "RSI Shares") of common stock, par value $.01 per
share, of Reckson Service Industries, Inc., a Delaware corporation ("RSI")
(which equates to a value of Nineteen Dollars ($19.00) per RSI Share) to each
Seller who is an "accredited investor," as that term is defined in Regulation
D under the Securities Act of 1933, as amended. If the Buyer does not deliver
to the Sellers an Exercise Notice (as defined in Section 1.2(c) below), the
cash portion of the Purchase Price shall be reduced by One Million Two Hundred
Twenty Eight Thousand Ninety Eight Dollars and sixty six cents
($1,228,098.66), which represents the aggregate exercise price of the Options
and Warrants.

          (b) Simultaneous with the execution and delivery of this Agreement,
the Buyer is delivering Five Million ($5,000,000.00) Dollars (the "Deposit")
to Herrick, Feinstein LLP, counsel to the Buyer, to be held in escrow for the
benefit of the Sellers as a down payment towards the Purchase Price pursuant
to the Escrow Agreement attached hereto as Exhibit B. Sellers agree that the
Buyer, in its sole discretion, can substitute the cash Deposit with an
irrevocable letter of credit, in form acceptable to the Sellers in their
reasonable judgment, in the amount of the Deposit for the benefit of the
Sellers. Upon termination of this Agreement as a result of the failure of any
of the conditions contained in Section 6.1 of this Agreement being satisfied,
the Deposit shall be immediately returned to the Buyer. Upon execution and
delivery of this Agreement, Herrick, Feinstein LLP shall provide written
confirmation to the Sellers that it has received the Deposit and that it is
holding the Deposit for the benefit of the Sellers in accordance with the
terms of this Section 1.2(b). If this Agreement is terminated or not performed
by the Buyer for any reason other than the failure of any of the conditions
contained in Section 6.1 of this Agreement being satisfied, the Deposit shall
be immediately delivered to the Sellers. Upon Closing, the Deposit shall be
delivered to the Sellers.

          (c) The Sellers agree that anytime after forty-five (45) days from
the date of this Agreement, the Buyer, in its sole discretion, can direct the
Sellers, upon notice (the "Exercise Notice") thereto, to exercise the Options
and Warrants. The Buyer, if it so determines, will deliver the Exercise Notice
with sufficient time to enable the Sellers to duly exercise the Options and
Warrants and obtain, prior to the Closing Date (as defined below), the stock
certificates evidencing the Class A Common Stock issued upon exercise of the
Options and Warrants. If the Sellers become the record and beneficial owners
of Class A Common Stock as a result of the exercise or conversion of the
Options and Warrants, all references in this Agreement to the Transferred
Shares shall be deemed to include such Class A Common Stock in lieu of the
Options and Warrants.

          (d) Upon the one-year anniversary date of the Closing and for thirty
days thereafter (time being of the essence), the Sellers who owned shares of
Series A Stock that were transferred to the Buyer and have been paid the
Purchase Price, in part, with RSI Shares, may request, by written notice to
RSI, that RSI pay such Sellers the difference between $19.00 per RSI Share
received as part of the Purchase Price and held by such Sellers on the date
such notice is given and the closing price (if lower than $19.00) of the RSI
Shares on the date such notice is given, provided, however, that (i) the right
to give such notice to RSI shall automatically and irrevocably expire if the
average of the volume weighted average closing price of RSI Shares for any
consecutive fifteen (15) days commencing from the date of this Agreement prior
to the giving of the aforesaid notice is $19.00 per share or higher and (ii)
the right to such payment at all times shall be adjusted to take into account
any additional shares of RSI stock or other securities that are acquired by or
issuable to the Sellers after the Closing by reason of stock rights or
options, warrants, stock splits, stock distributions, stock dividends or other
similar mechanisms or events by which additional shares of stock are conveyed
or will be conveyed to the Sellers by reason of their holding or having held
the RSI Shares as part of the Purchase Price.

          SECTION 1.3 Closing; Closing Date.

          (a) Subject to the terms and conditions of this Agreement, the sale
and purchase of the Transferred Shares contemplated hereby shall take place at
a closing (the "Closing") to be held at the offices of Herrick, Feinstein LLP,
2 Park Avenue, New York, New York 10016 at 10:00 A.M. local time, on the
ninetieth (90th) day following the delivery of the Offer Notice to the Company
and the Securityholder Offerees (as such term is defined in the Stockholders'
Agreement), or at such other time or on such other date as the Buyer and the
Sellers may mutually agree upon in writing. The day upon which the Closing
shall occur is herein called the "Closing Date". On a date that the Buyer and
the Sellers mutually agree upon, but in no event later than the seventh (7th)
day from the date this Agreement is executed, the Sellers shall deliver, in
accordance with Section 9.7 of the Stockholders' Agreement, (i) to the Company
(x) the Offer Notice, (y) the resignation letters in the form attached hereto
as Exhibit C executed by each of DW and G. Lee Bohs, and (z) a written consent
and action ("Stockholders' Consent"), in the form annexed as Exhibit D
electing Jason M. Barnett and Jeffrey D. Neumann as directors in place of DW
and G. Lee Bohs, executed by the Sellers and RSI, Buyer, Interoffice
Superholdings, LLC and Reckson Office Centers, Inc. and (ii) to each of the
Securityholder Offerees, the Offer Notice and the Stockholders Consent.

          (b) At the Closing, the Sellers shall deliver or cause to be
delivered to the Buyer the stock certificates evidencing all the Transferred
Shares, duly endorsed in blank or accompanied by stock powers duly executed in
blank, in proper form for transfer and with all required stock transfer tax
stamps affixed.

          (c) At the Closing, the Buyer shall deliver or cause to be delivered
to the Sellers the Purchase Price less the Deposit, as indicated on Schedule A
annexed hereto.

                                  ARTICLE II
                 REPRESENTATIONS AND WARRANTIES OF THE SELLERS

          The Sellers hereby jointly and severally represent and warrant to
the Buyer and RSI the following, which representations and warranties shall be
true and correct on the date of this Agreement and on the Closing Date:

          SECTION 2.1 Ownership of the Transferred Shares.

          (a) Each of the Sellers is the record and beneficial owner of the
number and type of Transferred Shares indicated opposite its or his respective
name on Schedule A annexed hereto and has good and marketable title to the
Transferred Shares, free and clear of all Liens, other than the restrictions
imposed by the Stockholders' Agreement, and neither CW, SA nor DW nor its or
his respective affiliates have any interest, directly or indirectly, in any
shares of capital stock, or other equity in the Company, or have any other
interest in any tangible or intangible property which the Company uses or has
used in the business conducted by the Company or otherwise, or have any
outstanding indebtedness to or from the Company. Upon consummation of the
transactions contemplated by this Agreement and payment of the Purchase Price,
(i) the Buyer shall be the lawful record and beneficial owner of the
Transferred Shares, including the Class A Common Stock issuable upon
conversion or exercise of the Transferred Shares in accordance with its
respective terms, free and clear of all Liens, other than the restrictions
imposed by the Stockholders' Agreement (except for the right of first refusal
pursuant to Section 4.3 thereof (the "Right of First Refusal") as such right
pertains to this Agreement), and (ii) the Transferred Shares, including the
Class A Common Stock issuable upon conversion or exercise of the Transferred
Shares in accordance with its respective terms, have been paid for by the
Sellers and the Sellers have received an opinion of the Company's counsel that
the shares of the Series A Stock were fully paid and nonassessable. Other than
the Stockholders' Agreement and as contemplated by this Agreement, there are
no stockholders' agreements, voting trusts, proxies, or other agreements or
understandings with respect to the Transferred Shares.

          (b) The Options and Warrants are transferable to the Buyer, and if
the Options and Warrants are sold to the Buyer in accordance with this
Agreement, the Buyer shall have all right, title and interest in the Options
and the Warrants, including, without limitation, the right to exercise the
Options and Warrants in accordance with their respective terms.

          SECTION 2.2 Authority. Each of CW and SA is duly organized and
validly existing under the laws of the state of its organization and is duly
registered and qualified to do business in each jurisdiction where such
registration or qualification is required and has been duly authorized by all
necessary and appropriate partnership action to enter this Agreement and
consummate the transactions contemplated herein, and the individuals executing
this Agreement on behalf of each of CW and SA have been duly authorized by all
necessary and appropriate action on behalf of CW and SA, respectively. Each of
the Sellers has the absolute and unrestricted right, power and authority to
execute and deliver this Agreement and all documents and instruments specified
herein, to carry out its or his obligations hereunder and to consummate the
transactions contemplated hereby. This Agreement has been duly executed and
delivered by each of the Sellers and, assuming due authorization, execution
and delivery by the Buyer, this Agreement constitutes a legal, valid and
binding obligation of the Sellers, enforceable against each of the Sellers in
accordance with its terms, subject to applicable bankruptcy, insolvency,
fraudulent conveyance, reorganization, moratorium and similar laws affecting
creditors' rights and remedies generally, and subject, as to enforceability,
to general principles of equity, including principles of commercial
reasonableness, good faith and fair dealing (regardless of whether enforcement
is sought in a proceeding at law or in equity).

          SECTION 2.3 Approval of Transaction; No Conflict. The execution and
delivery of this Agreement by the Sellers does not, and the performance of
this Agreement by the Sellers will not, require any consent, approval,
authorization or other action by, or filing with or notification to, any
person, entity, governmental authority or regulatory authority, other than
those required in connection with the Stockholders' Agreement. The General
Partner of each of CW and SA, and every partner whose consent is required, has
duly authorized the execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby, and such authorization
shall not have been amended, modified or withdrawn in any manner prior to the
Closing Date. Furthermore, the execution, delivery and performance of this
Agreement by each of the Sellers does not and will not (x) conflict with or
violate any agreement, law, rule, regulation, order, writ, judgement,
injunction, decree, determination or award to which any of the Sellers is a
party or (y) result in the creation of any Liens on the Transferred Shares.

          SECTION 2.4 Investment Intent. Each of the Sellers is acquiring the
RSI Shares for its or his own account, for investment purposes only and not
with a view to or for sale in connection with any distribution thereof. Each
of the Sellers is an "accredited investor", as that term is defined in
Regulation D under the Securities Act of 1933, as amended (the "Securities
Act"). Each of the Sellers has obtained all information it considers necessary
or appropriate for deciding whether to accept the RSI Shares. Each of the
Sellers acknowledges that it or he, as the case may be, is able to evaluate
and has such knowledge and experience in financial or business matters that it
or he, as the case may be, is capable of evaluating the merits and risks of
acquiring the RSI Shares, has the ability to protect its own interests in this
transaction and is financially capable of bearing the total loss of its
investment in the RSI Shares. Each of the Sellers understands that such Seller
must bear the economic risk of investment in the RSI Shares for an indefinite
period of time. Each Seller also understands that the RSI Shares have not been
registered under the Securities Act and, therefore, cannot be resold unless
they are registered under the Securities Act or unless an exemption from
registration is available. The Sellers will not transfer or otherwise dispose
of the RSI Shares except in accordance with applicable federal and state
securities laws or the rules and regulations promulgated thereunder.

          SECTION 2.5 No Material Facts Omitted. No representation or warranty
of any of the Sellers in this Agreement contains any untrue statement of a
material fact or omits to state a material fact necessary to make the
statements contained herein not misleading.

                                  ARTICLE III
              REPRESENTATIONS AND WARRANTIES OF THE BUYER AND RSI

          Buyer and RSI hereby jointly and severally represent and warrant to
the Sellers the following, which representations and warranties shall be true
and correct on the date of this Agreement and on the Closing Date:

          SECTION 3.1 Authority. Each of Buyer and RSI is a corporation duly
organized, validly existing and in good standing under the laws of the State
of Delaware. Each of Buyer and RSI has full corporate power and authority to
execute and deliver this Agreement and all documents and instruments specified
herein, to carry out its obligations hereunder and to consummate the
transactions contemplated hereby. This Agreement has been duly executed and
delivered by the Buyer and RSI, and assuming due authorization, execution and
delivery by the Sellers, constitutes a legal, valid and binding obligation of
the Buyer and RSI, enforceable against the Buyer and RSI in accordance with
its terms, subject to applicable bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium and similar laws affecting creditors'
rights and remedies generally, and subject, as to enforceability, to general
principles of equity, including principles of commercial reasonableness, good
faith and fair dealing (regardless of whether enforcement is sought in a
proceeding at law or in equity).

          SECTION 3.2 Approval of Transaction; No Default. The execution and
delivery of this Agreement by the Buyer and RSI does not, and the performance
of this Agreement by the Buyer and RSI will not, require any consent,
approval, authorization or other action by, or filing with or notification to,
any person, entity, governmental authority or regulatory authority, other than
those required in connection with the Stockholders' Agreement. The Board of
Directors of each of the Buyer and RSI has duly authorized the execution and
delivery of this Agreement and the consummation of the transactions
contemplated hereby, and such authorization shall not have been amended,
modified or withdrawn in any manner prior to the Closing Date. Furthermore,
the execution, delivery and performance of this Agreement by the Buyer and RSI
does not and will not conflict with or violate any agreement, law, rule,
regulation, order, writ, judgment, injunction, decree, determination or award
applicable to the Buyer or RSI.

          SECTION 3.3 Investment Intent. The Buyer is acquiring the
Transferred Shares for its own account, for investment purposes only and not
with a view to distribution of the Transferred Shares. The Buyer is an
"accredited investor", as that term is defined in Regulation D under the
Securities Act. The Buyer has requested all information it considers necessary
or appropriate for deciding whether to acquire the Transferred Shares. The
Buyer acknowledges that it is able to evaluate and has such knowledge and
experience in financial or business matters that it is capable of evaluating
the merits and risks of acquiring the Transferred Shares, has the ability to
protect its own interests in this transaction and is financially capable of
bearing the total loss of its investment in the Transferred Shares. The Buyer
will not transfer or otherwise dispose of the Transferred Shares except in
accordance with applicable federal and state securities laws or the rules and
regulations promulgated thereunder.

          SECTION 3.4 RSI Shares. The RSI Shares have been duly authorized
and, upon issuance therefor in accordance with the provisions of this
Agreement, will be validly issued, fully paid and non-assessable, and have
been issued in compliance with the registration requirements (or applicable
exemptions therefrom) of all applicable state and federal laws concerning the
issuance of securities.

          SECTION 3.5 SEC Documents. RSI has filed all required reports, forms
and other documents required to be filed under the Securities Exchange Act of
1934, as amended (the "Exchange Act"), with the Securities and Exchange
Commission ("SEC") since December 31, 1998 (the "RSI SEC Documents"). As of
their respective dates, the RSI SEC Documents complied in all material
respects with the requirements of the Exchange Act, and the rules and
regulations of the SEC promulgated thereunder applicable to such RSI SEC
Documents.

          SECTION 3.6 Independent Analysis. The Buyer and RSI recognize that
the Sellers have not made any representation or warranty upon which the Buyer
is relying in respect to the operations or prospects of the Company. The Buyer
and RSI are entering into this Agreement and Buyer and RSI are purchasing the
Transferred Shares solely based upon its independent analysis of the Company
and the representations and warranties set forth in Article II.

          SECTION 3.7 No Material Facts Omitted. No representation or warranty
of either the Buyer or RSI in this Agreement contains any untrue statement of
a material fact or omits to state a material fact necessary to make the
statements contained herein not misleading.

                                  ARTICLE IV
                              REGISTRATION RIGHTS

          SECTION 4.1. Demand Registration Rights. If RSI shall receive a
written request from the Sellers that RSI file a registration statement under
the Securities Act, then RSI shall, within ninety (90) days of the receipt
thereof, file a registration statement under the Securities Act for the RSI
Shares that the Sellers requested to be registered, PROVIDED, HOWEVER, that if
RSI completes an underwritten offering of its securities and in connection
therewith agrees with the underwriter(s) not to file a registration statement
with respect to the sale of its securities for a certain period subsequent to
the offering (the "Lock-Up Period"), RSI's obligation to file a registration
statement hereunder shall be deferred until the expiration of the Lock-Up
Period, which Period shall in no event exceed six (6) months. All expenses
incurred by RSI in complying with the request of the Sellers, including,
without limitation, all registration and filing fees, printing expenses, fees
and disbursements of counsel for RSI, shall be borne by RSI. All underwriting
discounts and selling commissions applicable to the sale of the RSI Shares
shall be borne by the Sellers pro rata on the basis of the number of RSI
Shares registered. All fees and disbursements of counsel for the Sellers, not
to exceed $20,000 in the aggregate, shall be borne by RSI. Sellers shall have
the right to two (2) requests for registration pursuant to this Section 4.1. A
holder of RSI Shares pursuant to this Agreement shall be entitled to the
registration rights granted hereunder so long as at the time the request for
registration is made, such request is made by the holders pursuant to this
Agreement of not less than 210,000 RSI Shares in the aggregate.

          SECTION 4.2 Indemnification. In the event any RSI Shares are
included in a registration statement, to the extent permitted by law, the
Sellers shall jointly and severally indemnify and hold harmless RSI, each of
its directors, officers and each person, if any, who controls RSI within the
meaning of the Securities Act, against any losses, claims, damages or
liabilities (joint or several), including, without limitation, reasonable
attorneys' fees and expenses (collectively, "Losses") to which RSI or any such
director, officer, or controlling person may become subject under the
Securities Act, the Securities Exchange Act of 1934, as amended (the "Exchange
Act") or other federal or state law, insofar as such Losses (or actions in
respect thereto) arise out of or are based upon any of the following
statements, omissions or violations (collectively, "Violations") by any of the
Sellers: (i) any untrue statement or alleged untrue statement of a material
fact contained in such registration statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the
statements therein not misleading, or (iii) any Violation or alleged Violation
by any of the Sellers of the Securities Act, the Exchange Act, any state
securities law or any rule or regulation promulgated under the Securities Act,
the Exchange Act or any state securities law in connection with the offering
covered by the registration statement. If the indemnification provided for
hereunder is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any Loss, the Sellers, in lieu of
indemnifying such indemnified party, shall to the extent permitted by
applicable law contribute to the amount paid or payable by such indemnified
party as a result of such Loss in such proportion as is appropriate to reflect
the relative fault of the Sellers on the one hand and the indemnified party on
the other in connection with the Violations that resulted in the Loss, as well
as any other relevant equitable considerations.

          SECTION 4.3 Termination of Registration Rights. The demand
registration rights granted hereunder shall terminate and be of no further
force and effect three (3) years from the Closing Date.

                                   ARTICLE V
      SELLERS' COVENANTS; BREAK-UP FEE; NO SOLICITATION; CONFIDENTIALITY

          SECTION 5.1 Waiver of Right of First Refusal. Each of the Sellers
hereby unconditionally and irrevocably waives its or his, as the case may be,
right to purchase all or any portion of the Transferred Shares pursuant to the
Right of First Refusal.

          SECTION 5.2 Voting with Respect to the Transferred Shares. Each of
the Sellers agrees that in each situation where it or he, as the case may be,
is entitled to vote at any meeting of stockholders of the Company (whether
annual or special and whether or not an adjourned or postponed meeting) or
consent in lieu of any such meeting or otherwise, the Seller shall not vote or
consent without first notifying the Buyer at least three business days prior
thereto as to how the Seller intends to vote. The Buyer shall have three
business days thereafter to notify the Seller of its objection, if any, to the
manner in which the Seller intends to vote or consent, and the failure of the
Buyer to notify the Seller within such period shall be deemed its approval of
the Seller's vote on such matter.

          SECTION 5.3 Replacement of Directors; Break-Up Fee.

          (a) The Sellers agree to cooperate with the Buyer and RSI in the
prompt election of Jason M. Barnett and Jeffrey D. Neumann to serve as members
of the board of directors of the Company (the "Successor Nominees") to replace
DW and G. Lee Bohs. The Sellers agree to take any and all actions necessary to
effectuate and continue the foregoing, including, without limitation, the
delivery of the resignation letters of DW and G. Lee Bohs to the Company
promptly after the date hereof, the nomination of the Successor Nominees and
to vote the Transferred Shares for the election of the Successor Nominees at
any special meeting or consent in lieu of a meeting called for the purpose
thereof.

          (b) In the event that prior to the time the Successor Nominees are
elected to the board of directors of the Company in accordance with Section
5.2(a) above, (x) the Company exercises its Right of First Refusal to purchase
any or all of the Transferred Shares (which means that DW and G. Lee Bohs vote
in favor of such purchase) and the majority of the four directors of the
Company who have been designated by RSI do not vote in favor of such purchase,
and (y) the transaction contemplated by this Agreement is not consummated as a
result of the failure of the condition contained in Section 6.1(a) of this
Agreement being satisfied, then the Sellers hereby covenant and agree to pay
to the Buyer, simultaneously with the payment by the Company and/or the
Securityholder Offerees to the Sellers, the amount which is equal to (i) the
amount received by each Seller which is in excess of $5.25 per Transferred
Share multiplied by (ii) the aggregate number of Transferred Shares sold by
the Sellers.

          SECTION 5.4 No Solicitation. Upon execution and delivery of this
Agreement until the Closing, none of the Sellers shall, directly or
indirectly, through any officer, director, partner, agent, employee,
representative or otherwise, except pursuant to Section 4.3 of the
Stockholders' Agreement, (i) solicit, initiate or encourage the submission of
any inquiries, proposals or offers from any person or entity relating to the
purchase of the Transferred Shares or any legal or interest therein or the
creation or imposition of any Lien thereon (collectively, a "Third Party
Purchase"); (ii) consider or accept any agreement, arrangement or
understanding with respect to a Third Party Purchase; (iii) participate in any
discussion, negotiations or other communications regarding any Third Party
Purchase; (iv) furnish to any person or entity other than the Buyer and its
representatives any information concerning the Transferred Shares; (v) grant,
issue or agree to grant or issue to any person or entity: (a) any direct or
indirect interest in CW or SA or (b) any right or option to acquire any such
interest; or (vi) cooperate in any way, assist or participate in, facilitate
or encourage any effort or attempt by any person or entity other than the
Buyer to seek to do any of the foregoing.

          SECTION 5.5 Confidentiality.

          (a) Each of the parties agrees, on behalf of themselves and himself,
as the case may be, and their respective affiliates and representatives, to
retain in strict confidence, and not to divulge, disseminate or disclose to
any third party (other than as may be required by the Stockholders' Agreement,
court order, law, rule or regulation) the existence of this Agreement or any
of the terms hereof, without the prior written consent of all the parties
hereto, which consent shall not be unreasonably withheld, conditioned or
delayed. The parties further agree to consult with each other prior to making
any public disclosure (other than as set forth herein) relating to the
transactions contemplated herein.

          (b) In addition to any and all other remedies available at law or
equity, in the event any or all of the Sellers shall breach or threaten to
breach any of the provisions of this Article V of this Agreement, each of the
Sellers agrees and acknowledges that damages would be difficult to ascertain,
the Buyer and its affiliates will suffer immediate, irreparable harm, and the
Buyer and its affiliates shall be entitled, in addition to any and all other
remedies, to an injunction issued by a court of competent jurisdiction
restraining the aforesaid violations of any or all of the Sellers, as the case
may be, without the necessity of posting a bond. Nothing contained in this
Section 5.5(b) is intended to limit in any way any of the rights or remedies
of any party to this Agreement in respect of any breach or threatened breach
of this Article V or any other provision of this Agreement.

                                  ARTICLE VI
                             CONDITIONS TO CLOSING

          SECTION 6.1 Conditions to the Obligation of the Buyer to Close. The
obligation of the Buyer to consummate the transactions contemplated by this
Agreement shall be subject to the fulfillment, as at the Closing Date, of each
of the following conditions, any one or more of which may be waived by the
Buyer:

          (a) Failure to Exercise the Right of First Refusal. The failure of
the Company and the Securityholder Offerees (i) to exercise their Right of
First Refusal to purchase the Transferred Shares or (ii) to close on such
purchase if exercised; upon occurrence of the first of such failures, there
shall be deemed an automatic acceptance by the Sellers of the offer contained
in this Agreement by operation of law.

          (b) Vote of Stockholders. None of the Sellers has voted or consented
to any matter to which the Buyer has objected pursuant to Section 5.2 of this
Agreement.

board of directors for a vote prior to the time that the Successor Nominees

nominated by CW and SA have voted in the same way on the matter presented as
has been voted by the majority of the directors nominated by RSI.

          (d) Performance of Covenants. Each of the Sellers shall have
performed and complied in all material respects with all covenants,

limited to, the transfer of all of the Transferred Shares to Buyer in the

deficiencies and penalties and interest thereon), and costs and expenses

                   Price and the Series B Proceeds credit to the Purchase
                   Price) if the only approval not obtained is HSR Act
                   approval, or (ii) terminate this Agreement and all of the
                   transactions contemplated hereby in their entirety.

                   (iii)the simultaneous closing under the Rabinowitz

                        fail to close under the Rabinowitz Acquisition
                        Agreement, then Buyer may, at its option, close on
                        behalf of Sellers); and

                   (iv) as an additional condition to the closing of the
                        Vantas Sale, HSR Act approval, if necessary (and the
                        parties agree that, in the event that such approval is

                        including reasonable attorney's fees of the attorneys
                        designated by Buyer to represent Buyer and the Sellers
                        in connection with preparing, filing and processing
                        the application under the HSR Act).

         5.   VANTAS SALE. JAH shall sell (the "Vantas Sale") to Buyer all of
              the JAH I/O Interests on the following terms:

              (a)  At the time this Agreement is executed and delivered, the
                   Buyer shall deposit into escrow with the Buyers' counsel,
                   Herrick, Feinstein LLP ("HF"), pursuant to an escrow
                   agreement in the form annexed hereto as Exhibit IV, a $2.3
                   million principal amount irrevocable standby letter of
                   credit in a form reasonably acceptable to Sellers, such
                   deposit representing part of the Vantas Sale purchase
                   price.

              (b)  The Vantas Sale shall close concurrently with the
                   consummation of the purchase (the "Cahill Sale") by Buyer
                   of the VANTAS Incorporated ("Vantas") securities (the
                   "Cahill Shares") of Warnock Strategic Partners Fund L.P.,
                   Strategic Associates, L.P. and David L. Warnock
                   (collectively, "Cahill") whether the Cahill Sale is
                   consummated in whole or in part; provided, however, that
                   JAH may elect to postpone the closing until any date up to
                   and including January 14, 2000, by giving a notice to Buyer
                   not later than five (5) business days after receipt by JAH
                   of written notice of the scheduled closing date of the
                   Cahill Sale. In the event the Cahill Sale is not
                   consummated, in whole or in part, prior to January 5, 2000,
                   then the Vantas Sale shall be consummated not later than
                   January 14, 2000.

              (c)  With respect to 345,241 shares of RSI Stock received upon
                   the closing of the Vantas Sale: upon the one-year
                   anniversary of the closing date and for thirty days
                   thereafter (time being of the essence), JAH (or, if
                   applicable, JAH's Permitted Successor) may request, by
                   written notice to Buyer, that Buyer pay to such party an
                   amount equal to (x) the difference between $19 per share of
                   RSI Stock and the closing price (if lower than $19) of RSI
                   Stock on the date such notice is given multiplied by (y)
                   the lesser of 345,241 and the number of shares of RSI Stock
                   Owned by such party on the date such notice is given,
                   provided, however, that (i) this right shall automatically
                   and irrevocably expire if the average of the volume
                   weighted average closing price (the "VWAP") of RSI Stock
                   for any consecutive fifteen day period (the "15 Day
                   Period") commencing from the date of this Agreement prior
                   to the giving of the aforesaid notice is $19 per share or
                   higher, and (ii) the right to such payment shall at all
                   times be adjusted for any stock dividend, stock split,
                   other distribution or reclassification of RSI Stock
                   applicable to all record holders of RSI Stock generally;
                   and provided further, however, that if the underwriter


<PAGE>


                   lock-up agreement referred to in Section 13(c) is in effect
                   and precludes Sellers from selling 345,241 shares of RSI
                   Stock during the effectiveness of such lock-up agreement,
                   then the RSI Stock closing price during such lock-up period
                   shall be excluded in calculating the VWAP, and the day
                   immediately preceding the effectiveness of such lock-up
                   period and the day immediately following the termination of
                   such lock-up period shall be deemed to be consecutive days
                   for purposes of calculating the 15 Day Period.

              (d)  With respect to 86,310 shares of RSI Stock received upon
                   the closing of the Vantas Sale: upon the one-year
                   anniversary of the closing date and for thirty days
                   thereafter (time being of the essence), JAH (or, if
                   applicable, JAH's Permitted Successor) may request, by
                   written notice to Buyer, that Buyer pay to such party an
                   amount equal to (x) the difference between $15 per share of
                   RSI Stock and the closing price (if lower than $15) of RSI
                   Stock on the date such notice is given multiplied by (y)
                   the lesser of 86,310 and the number of shares of RSI Stock
                   Owned by such party on the date such notice is given,
                   provided, however, that (i) this right shall automatically
                   and irrevocably expire if the average of the VWAP of RSI
                   Stock for any 15 Day Period prior to the giving of the
                   aforesaid notice is $15 per share or higher, and (ii) the
                   right to such payment shall at all times be adjusted for
                   any stock dividend, stock split, other distribution or
                   reclassification of RSI Stock applicable to all record
                   holders of RSI Stock generally; and provided further,
                   however, that if the underwriter lock-up agreement referred
                   to in Section 13(c) is in effect and precludes Sellers from
                   selling 86,310 shares of RSI Stock during the effectiveness
                   of such lock-up agreement, then the RSI Stock closing price
                   during such lock-up period shall be excluded in calculating
                   the VWAP, and the day immediately preceding the
                   effectiveness of such lock-up period and the day
                   immediately following the termination of such lock-up
                   period shall be deemed to be consecutive days for purposes
                   of calculating the 15 Day Period.

              (e)  Effective upon the closing of the Vantas Sale, JAH and its
                   partners, Affiliates, agents and representatives shall be
                   indemnified and held harmless by Buyer from all
                   liabilities, obligations, claims or damages brought or
                   asserted by third parties or otherwise arising out of, in
                   connection with or as a result of JAH I/O being or having
                   been a member of ISC for acts or omissions by the
                   indemnified party other than acts or omissions for which
                   Sellers are indemnifying Buyer. Effective upon the closing
                   of the Vantas Sale, Buyer and its Affiliates, agents and


<PAGE>


                   representatives shall be indemnified and held harmless by
                   Sellers, jointly and severally, from all liabilities,
                   obligations, claims or damages brought or asserted by third
                   parties or otherwise arising out of, in connection with or
                   as a result of wilful acts or wilful omissions or gross
                   negligence of JAH I/O in respect of ISC prior to the
                   closing date of the Vantas Sale.

                   release the other and their respective Affiliates, agents
                   and representatives from any and all claims arising prior
                   to the closing date of the Vantas Sale that they have or
                   may have with respect to ISC except for the obligations set
                   forth in this Agreement.

              (g)  For a period of three years after the closing date of the
                   Vantas Sale, RSI shall cause Jon Halpern to be elected a
                   director and named Vice Chairman of the Vantas board of
                   directors (the "Vantas Board"). As a director of Vantas,
                   Jon Halpern: (i) shall be subject to the laws of fiduciary
                   duty applicable to a director under the corporate law of
                   the jurisdiction where Vantas is then incorporated and
                   applicable securities laws and may be removed from the

                   director appointed by RSI has signed or has agreed to sign
                   the applicable registration statement; and (iii) may be
                   removed from the Vantas Board for any misappropriation of
                   any corporate opportunity of Vantas; provided, however that
                   Jon Halpern may not be removed from the Vantas Board
                   pursuant to this clause (iii) for engaging in any activity
                   which is then engaged in by RSI or its Affiliates other
                   than through Vantas.

              (h)  For a period of three years after the closing date of the
                   Vantas Sale, RSI shall cause Jon Halpern to be appointed to
                   the RSI Strategic Steering Committee. Notwithstanding the
                   foregoing, RSI may remove Jon Halpern from such appointment
                   for cause.

                   contrary, the parties agree that Sellers shall not be
                   liable for (i) any obligations paid or payable to the

                   LLC;. (ii) any obligations paid or payable to any holder of
                   options to purchase Class A Units in ISC pursuant to the
                   ISC LLC Agreement and/or any employment or option agreement
                   with such option holder and (iii) any obligations for which
                   ISC has indemnified Vantas at the time of the January, 1999

              below) and/or the ISC LLC Agreement; provided, however, that if
              the Vantas Sale does not close, then JAH I/O shall have the

              entitled to acquire if RSI, Reckson Office Centers LLC, RSI I/O
              Holdings, Inc. and ISC had each exercised in full all of their
              preemptive rights, as regards the Series D Stock and Series E
              Stock, and the right of first refusal rights of each such entity
              to all of the Cahill Shares (to the extent the Cahill Shares are
              actually purchased by any or all of RSI, Reckson Office Centers
              LLC, RSI I/O Holdings, Inc. and ISC and/or their respective

                   securities generally); and provided further, however, that
                   in the event that Code Section 856(d)(5) is altered,
                   amended or modified so that the reference therein to "10
                   percent" is increased, RSI shall endeavor to provide an
                   ownership limit exception that makes a corresponding
                   increase to the ownership limit with respect to the common
                   stock of RSI and capital stock of RSI for the Sellers upon
                   their request, to be effective not earlier than five years
                   after the closing date of the Acquisition (other than the
                   Vantas Sale). Notwithstanding the foregoing, no approval of
                   the RSI board of directors shall be required if any Seller
                   only acquires additional securities in RARC.

              (b)  Buyer shall use its commercially reasonable efforts (which
                   efforts shall not include the payment of money or granting
                   of other consideration) upon the closing of the Vantas Sale
                   to modify the Fifth and Amended and Restated Vantas
                   Stockholders' Agreement to remove the non-competition
                   covenants applicable to Sellers and, to the extent
                   applicable, their Affiliates.

              (c)  Any and all amounts payable to Buyer in respect of Series B
                   Proceeds shall be paid (or, if applicable, assigned) by
                   Sellers within two business days after receipt.

              (d)  In addition to any rights that Buyer may have arising from
                   or in connection with any breach by Sellers of a
                   representation, warranty or covenant set forth in this
                   Agreement, Buyer shall have the right to deduct and set-off
                   from any amounts payable to Sellers an amount equal to the
                   costs, liabilities, damages and expenses, including
                   attorneys' fees, resulting from such breach or which Buyer
                   in good faith reasonably anticipates will result from such
                   breach; provided, however, that prior to such deduction or
                   set-off Buyer (i) provides JAH with a notice describing the
                   alleged breach and the calculation of the amount of such
                   deduction and/or set-off, and (ii) provides a letter of
                   credit or other comparable security so that if Sellers
                   prevail in a litigation concerning such breach, Sellers can
                   be paid from such security. In any litigation pursuant to
                   this provision, the prevailing party shall recover all
                   legal fees and costs including, in the case of Buyer, all
                   costs of the letter of credit or other security. The
                   parties understand that this Section 9(d) contemplates that
                   each sale (i.e., the OCC Sale, the OnSite Sale and the
                   Vantas Sale) provides a separate right to set-off for
                   breaches of representations, warranties and covenants
                   relating exclusively to that particular sale and that a
                   breach claimed under one sale cannot give rise to a right
                   of set-off pertaining to another sale.

         10.  INDEMNIFICATION. Buyer and Sellers agree to indemnify each other
              from any and all costs, liabilities, damages and expenses,
              including attorneys' fees, resulting from breach of the
              representations and warranties and covenants set forth in this
              Agreement.

         11.  REGISTRATION RIGHTS. Effective on the closing date of the
              Acquisition (other than the Vantas Sale), the Sellers shall have
              the right to require that RSI register under the Securities Act
              of 1933, as amended, the shares of RSI Stock issued to the
              Sellers pursuant to this Agreement on such closing date, in
              accordance with the terms of the Registration Rights Agreement
              annexed hereto as Exhibit V (the "Registration Rights
              Agreement"), which agreement shall be executed and delivered in
              the form annexed hereto on the closing date. Effective on the
              closing date of the Vantas Sale, the Sellers shall have the
              right to include the RSI Stock issued to Sellers pursuant to the
              Vantas Sale in the registration statement contemplated by the
              Registration Rights Agreement.

         Subject to Section 13, nothing in this Section 11 shall affect the
rights, if any, of Sellers to sell shares of RSI Stock under Rule 144 under
the Securities Act of 1933, as amended, or any successor rule or regulation.

         12.  TERMINATION OF AGREEMENTS.

              (a)  Concurrently with the closing of the OCC Sale and the
                   OnSite Sale without any further action by Buyer or Sellers,
                   the following agreement is terminated and of no further
                   force or effect:

                   the letter agreement dated December 24, 1997 by and among
                   Reckson Associates Realty Corp., Jon L. Halpern and Martin
                   Rabinowitz; provided, however, that the termination of such
                   letter agreement shall not modify or otherwise effect that
                   letter's provisions set forth in Sections 1.c., 2.a., 2.b.
                   and 2.f., which provisions shall not be modified by this
                   Agreement and shall continue in full force and affect.

              (b)  Concurrently at the closing of the Vantas Sale and without
                   any further action by Buyer or Sellers, the following
                   agreements are terminated and of no further force or
                   effect:

                   (i)  the letter agreement dated November 9, 1998 (the "Side
                        Letter") among JAH I/O, Reckson Management Group,
                        Inc., Buyer, RSI I/O Holdings, Inc. and Reckson Office
                        Centers, LLC; and


<PAGE>



                   (ii) Interoffice/Jon Halpern Terms Sheet dated September
                        24, 1998 by and among Reckson Management Group, Inc.,
                        Reckson Service Industries, Inc. and JAH I/O LLC.

         13.  LOCK-UP AGREEMENTS

              (a)  Sellers agree that so long as the members of the senior
                   management of RSI on the date hereof and their respective
                   Affiliates (such persons and entities, collectively, being
                   the "Rechler Persons"), Own, in the aggregate, more than
                   fifty percent (50%) of the RSI Stock (as adjusted for any
                   stock dividend, stock split, other distribution or
                   reclassification of RSI Stock applicable to all record
                   holders of RSI Stock generally) Owned by them in the
                   aggregate on the date of this Agreement, they will not,
                   without the prior written consent of Buyer, directly or
                   indirectly, other than as provided herein, for a period of
                   twelve (12) months after the date of the issuance of the
                   RSI Stock to the Sellers, offer, sell, contract to sell or
                   otherwise dispose of or transfer any shares of RSI Stock
                   received pursuant to this Agreement other than the
                   aggregate of 431,551 shares of the RSI Stock (received
                   under the Vantas Sale). This lock-up agreement shall not
                   prohibit (i) the Sellers from transferring RSI Stock to any
                   Affiliate of the Sellers, to any charitable organization,
                   or to any other party in connection with any family or
                   estate planning by Sellers or their Affiliates or by gift,
                   will or the laws of descent and distribution, provided that
                   such transferee agrees in writing to the transfer
                   restrictions described herein or (ii) the Sellers from
                   transferring during any three month period an amount of
                   shares of RSI Stock that does not exceed 10% of the RSI
                   Stock Owned by Sellers pursuant to this Agreement;
                   provided, however, that in no event during the 12 month
                   lock-up period of this Section 13, shall the Sellers sell
                   an aggregate of more than 1,000,000 shares of RSI Stock
                   (whether such shares are registered or not registered under
                   the registration statement contemplated by the Registration
                   Rights Agreement), including the RSI Stock received by
                   Sellers pursuant to the Vantas Sale;

              (b)  Sellers agree that so long as: (i) the Rechler Persons Own,
                   in the aggregate, more than fifty percent (50%) of the RSI
                   Stock (as adjusted for any stock dividend, stock split,
                   other distribution or reclassification of RSI Stock
                   applicable to all record holders of RSI Stock generally)
                   Owned by them on the date of this Agreement, and (ii)
                   Sellers and/or their respective Affiliates Own five percent
                   (5%) or more of the issued and outstanding RSI Stock, in
                   the aggregate, then Sellers and their respective Affiliates
                   will vote such stock on "change of control" issues
                   pertaining to RSI only (i) in such manner as the majority
                   of the RSI board of directors recommends or (ii) by


<PAGE>


                   abstaining; provided, however, that nothing contained in
                   this Section 13(b) shall prevent (i) Sellers or their
                   respective Affiliates from selling such shares to any
                   person or entity making a tender offer, exchange offer or
                   similar transaction for RSI Stock whether or not such sale
                   is recommended by a majority of the RSI board of directors
                   or (ii) Sellers from voting on any other matter for which
                   RSI stockholders are entitled to vote generally. For
                   purposes of this Section 13, "change of control" issues
                   consist solely of the following: (1) any proposed merger or
                   consolidation of RSI with or into any person, or any
                   proposed sale, transfer or other conveyance, whether direct
                   or indirect, of all or substantially all of the assets of
                   RSI, in one transaction or a series of related
                   transactions, if, immediately after giving effect to such
                   transaction any "person" or "group" (as such terms are used
                   for purposes of Section 13(d) and 14(d) of the Securities
                   Exchange Act of 1934, as amended (the "Exchange Act"),
                   whether or not applicable), is or becomes the beneficial
                   owner, directly or indirectly, of more than thirty-five
                   percent (35%) of the shares of the total voting power of
                   RSI, (2) a proposal under which any "person" or "group" (as
                   such terms are used for purposes of Section 13(d) and 14(d)
                   of the Exchange Act, whether or not applicable) would
                   become the beneficial owner, directly or indirectly, of
                   more than thirty-five percent (35%) of the total voting
                   power of RSI, or (3) a proposal under which any party would
                   receive the right to elect a majority of the RSI board of
                   directors or to control, directly or indirectly, a majority
                   of the RSI board of directors; and

              (c)  Notwithstanding the provisions of Section 13(a) above, if
                   RSI sells common stock or securities convertible into
                   common stock through an underwritten public offering during
                   the 12 month lock-up period, the Sellers (including their
                   successors and assigns) shall agree to enter into standard
                   underwriter lock-up agreements providing that the Sellers
                   (and/or such successors and assigns) will not offer, sell,
                   contract to sell or otherwise dispose of or transfer any
                   shares of RSI Stock for the identical lock-up period
                   provided for in the underwriter lock-up agreements entered
                   into by members of RSI's senior management; provided, that
                   in no event shall such period exceed 120 days; provided
                   however that (i) the Sellers shall be permitted in any
                   event to make the transfers provided for in Section
                   13(a)(i) above and Section 14 below without restriction or
                   limitation, (ii) that the term of the Registration Rights
                   Agreement shall be extended by the number of days by which


<PAGE>


                   the Sellers are subject to the underwriter's lock-up in
                   excess of sixty (60) days and (iii) that after the
                   expiration of the underwriter's lock-up, the Sellers shall
                   be permitted to increase the number of shares which they
                   may transfer in the next three month period under Section
                   13(a)(ii) by the number of shares which Sellers could not
                   transfer during the prior three month period because of the
                   underwriter's lock-up.

         14.  PLEDGES AND MARGIN. The lock-up agreements referred to in
              Section 13 of this Agreement shall not prohibit the Sellers
              and/or their Affiliates and their permitted successors and
              assigns from pledging their RSI Stock to any nationally
              recognized financial institution as collateral for a bona fide
              third party loan or from using the RSI Stock as margin
              collateral with a nationally recognized financial institution or
              broker/dealer pursuant to a bona fide third party transaction,
              provided, however, that such financial institution or
              broker/dealer shall not be subject to the lock-up provisions of
              Section 13 of this Agreement if and only if the aggregate fair
              market value of the collateral securing such loan or
              indebtedness is, as of the first day of such pledge or use, not
              more than 2 times the amount of such loan or indebtedness.
              Provided that Sellers have complied with the foregoing, Buyer
              will cooperate with effectuating the purposes of this Section
              14, including at Sellers' request, Buyer will promptly complete
              and sign any certificate, instrument or other document or
              perform any other action or thing that is reasonably requested
              or desired by any lender, Seller or its Affiliates in connection
              with the use of RSI stock as collateral for a loan and otherwise
              promptly take all other actions to carry out the provisions
              under this Section 14, all at Sellers' sole cost and expense
              (including Buyer's reasonable attorneys fees).

         15.  RIGHTS TO CERTAIN INFORMATION. Subject to RSI's fiduciary duties
              and any confidentiality obligations it may have, Jon Halpern
              will have the right to receive any and all information, reports,
              analysis and other access relating to the business, operations
              and prospects of RSI and its Affiliates which would be afforded
              to any institutional investor of RSI without becoming an
              "insider".

         16.  TIME OF THE ESSENCE. Time shall be of the essence with respect
              to all notices required to be given, all payments required to be
              made and all conditions required to be satisfied under this
              Agreement.

         17.  BROKER. Each of the parties agrees that no finder's fee or
              broker's commission shall by reason of its actions be payable by
              any other party in connection with the transactions contemplated
              hereby and no party knows of any such fees payable by any party.

         18.  FEES AND EXPENSES. Sellers and Buyer hereby agree that they will
              pay their own (and their representatives') respective fees and
              advances incurred in connection with the negotiation,
              preparation, execution and delivery of this Agreement and any
              other agreements or documents contemplated hereby or thereby.

         19.  PUBLICITY. No press release or other public statement shall be
              issued, nor shall the terms of this Agreement be disclosed to
              third parties other than the representatives of the parties,
              without the mutual consent of Buyer and Sellers; provided,
              however, that nothing herein shall prohibit Buyer from making
              any public statement that, on the advice of counsel, is required
              or advisable to make in order to comply with its obligations
              under applicable securities laws or stock exchange agreements.

         20.  BINDING AGREEMENT. This Agreement constitutes a binding
              agreement among the parties hereto and supercedes all prior
              agreements or understandings, written or oral, concerning the
              subject matter of this Agreement.

         21.  REMEDIES. The parties agree that damages may not be an adequate
              remedy in the event of a breach or threatened breach of this
              Agreement and, accordingly, each agrees that either party, their
              agents, representatives or the Affiliates of any of them, as the
              case may be, shall be entitled to equitable relief, including
              injunction and specific performance, in the event of any breach
              or threatened breach of the provisions of this Agreement, in
              addition to all other remedies available at law or in equity.

         22.  SEVERABILITY. Wherever possible, each provision of this
              Agreement shall be interpreted in such a manner as to be
              effective and valid under applicable law, but if any provision
              of this Agreement shall be prohibited by or invalid under such
              law, such provision shall be ineffective to the extent of such
              prohibition or invalidity without invalidating the remainder of
              such provision or the remaining provisions of this Agreement.

         23.  FURTHER ASSURANCES. At any time, and from time to time after the
              date hereof, each party shall, without further consideration and
              at its own cost and expense, execute and deliver such additional
              agreements, instruments, documents or certificates and take such
              further action as shall reasonably be requested by any other
              party to this Agreement in order to carry out the provisions of
              this Agreement, including, without limitation, taking any and
              all necessary actions reasonably requested by any party hereto
              to satisfy any regulatory filing requirements whether under the

         The parties hereto, in exchange for good and valuable consideration,
the receipt and sufficiency of which is hereby acknowledged, agree that the
Letter Agreement is amended as provided herein.

         1.   Section 4(a) and Section 4(b) of the Letter Agreement are hereby
              deleted in their entirety and replaced with the following:

              "(a) The closing of the OCC Sale (as defined below) shall occur
                   on September 29, 1999, provided that simultaneous with the
                   closing of the OCC Sale the transactions set forth in the
                   Rabinowtiz Acquisition Agreement shall also close. The
                   closing of the OnSite Sale shall occur on October 15, 1999,
                   or such earlier date as the parties may agree.

              (b)  Intentionally omitted."

         2.   Section 5 of the Letter Agreement is hereby amended by inserting
              a new paragraph after paragraph (i) thereof, which shall state
              as follows:



<PAGE>



              "(j) As an additional condition to the closing of the Vantas
                   Sale, Hart-Scott- Rodino Antitrust Improvements Act of
                   1976, as amended (the "HSR Act") approval, if necessary
                   (and the parties agree that, in the event such approval is
                   necessary, Buyer shall pay all fees and costs, including
                   reasonable attorney's fees of the attorneys designated by
                   Buyer to represent Buyer and the Sellers, in connection
                   with preparing, filing and processing the application under
                   the HSR Act)."

         3.   Section 9(a) of the Letter Agreement is hereby amended by
              deleting the words "Acquisition (other than the Vantas Sale)"
              that appear twice in the first sentence thereof and replacing
              them with the words "OCC Sale" in each place.

         4.   Section 9 of the Letter Agreement is hereby amended by inserting
              a new paragraph after paragraph (d) thereof, which shall state
              as follows:

              "(e) The parties agree that in the event that Buyer determines
                   that HSR Act approval is necessary or such HSR Act approval
                   is otherwise required in connection with the OnSite Sale,
                   then Buyer shall pay all fees and costs, including
                   reasonable attorney's fees of the attorneys designated by
                   Buyer to represent Buyer and the Sellers, in connection
                   with preparing, filing and processing any application under
                   the HSR Act."

         5.   Section 11 of the Letter Agreement is hereby amended by deleting
              the words "Acquisition (other than the Vantas Sale)" in the
              first sentence thereof and replacing them with the words"OnSite
              Sale".

         6.   Section 12(a) of the Letter Agreement is hereby amended by
              deleting the words "Concurrently with the closing of the OCC
              Sale and the OnSite Sale" and replacing them with the words
              "Concurrently with the closing of the OnSite Sale".

         7.   Section 13 of the Letter Agreement is hereby amended by
              inserting a new paragraph after paragraph (c) thereof, which
              shall state as follows:

              "(d) Notwithstanding anything contained herein to the contrary,
                   in the event that the OnSite Sale shall not close on or
                   prior to October 15, 1999, then JAH shall be entitled to
                   dispose of the 260,000 shares of RSI Stock issued to JAH in
                   connection with the OCC Sale in accordance with law and
                   without restriction imposed under this Agreement."

         8.   Other than as specifically set forth in this Amendment, all of
              the terms and conditions of the Letter Agreement shall remain in
              full force and effect. All references to the Letter Agreement
              after the date hereof shall automatically be

                  and agreed that the defined term "Agreement" includes,
                  collectively, the Letter Agreement and this Amendment.

         9.   This Amendment shall be governed by and construed in accordance
              with the laws of the State of New York applicable to contracts
              made and to be performed entirely in the State of New York.

         10.  This Amendment may be executed in any number of counterparts and
              by the parties hereto in separate counterparts, each of which
              when so executed shall be deemed an original and all of which
              taken together shall constitute one and the same agreement. This
              Agreement may be executed and delivered via facsimile machine by
              the parties, which shall be deemed for all purposes as original.
