          Re: Amendment to the Amended and Restated Credit Agreements

Dear Sirs:

     Reference  is  made  to the Amended and Restated Credit Agreement, dated as
of  August  4,  1999, as amended on November 30, 1999, between FrontLine Capital
Group,  as Borrower (the "Borrower") and Reckson Operating Partnership, L.P., as
Lender   (the  "Lender")  relating  to  the  operations  of  the  Borrower  (the
"FrontLine  Facility"),  and the Amended and Restated Credit Agreement, dated as
of  August  4,  1999,  as amended on November 30, 1999, between the Borrower and
the  Lender relating to the operations of Reckson Strategic Venture Partners LLC
(the  "RSVP  Facility"  and,  together  with the FrontLine Facility, the "Credit
Facilities").  Capitalized  terms  used  herein  and not otherwise defined shall
have the meaning ascribed to such terms in the Credit Facilities.

     The  following  amendments  to  the  Credit  Facilities  are  being made in
response  to  recent  tax  legislation  in  order  to protect Reckson Associates
Realty  Corp.'s  status  as  a  real  estate investment trust under the Internal
Revenue Code of 1986, as amended.

     This  letter  will confirm that, effective as of the date hereof, we hereby
amend the Credit Facilities as follows:

     1. Article  I,  Section  1.1(b) is hereby amended by deleting the following
definition:

       "Adjusted  EBITDA"  shall  mean,  for any fiscal quarter, EBITDA less any
   amounts  payable  (i)  by  any  subsidiary  in respect of the Indebtedness of
   such  Subsidiary  (including,  but  not  limited  to,  Indebtedness of VANTAS
   Incorporated  and  the  Secured $75 million Loan) and (ii) by the Borrower in
   respect of the Secured $60 million Loan.

     2. Article  III,  Section  3.1 is  amended  and restated in its entirety as
follows:

       Section  3.1 Interest  Rate.  Each Loan shall bear interest from the date
   made   until   the  date  repaid,  payable  in  arrears,  on  the  Commitment
   Termination  Date,  at  a  rate per annum equal to the greater of (i) the sum
   of  (x)  2%  and  (y)  the  Prime Rate for the applicable Interest Period and
   (ii)  12%.  With  respect  to  each  Loan outstanding for one year or longer,
   such  12%  rate shall increase to 12.48%, 12.98%, 13.50% and 14.04% as of the
   anniversary  of  the  making  of such Loan, for the second, third, fourth and
   fifth  years  that such Loan is outstanding, respectively. Payments under the
   Notes  shall  be  applied  first to any fees, costs or expenses due under the
   Notes   or   hereunder,   then   to   interest,   and   then   to  principal.
   Notwithstanding  any  other  provision  of  this  Agreement,  all outstanding
   principal  and  interest of the Loan and all other amounts payable hereunder,
   if  not  sooner  paid, shall be due and payable on the Commitment Termination
   Date.

     3. Article XI is hereby amended by adding the following section:

       Section  11.12 Participations.  The Lender may transfer participations to
   one  or  more  of  its Affiliates in or to all or a portion of its rights and
   obligations  under  and in respect of any and all Loans and Letters of Credit
   under this Agreement (including, without limitation, all or a portion


                                       26

   of  any  or  all of its Commitment hereunder; provided, however, that (i) the
   Lender's  obligations  under  this  Agreement (including, without limitation,
   its  Commitment  hereunder)  shall  remain  unchanged,  (ii) the Lender shall
   remain  solely  responsible  to  the  Borrower  for  the  performance of such
   obligations,  (iii)  the  Borrower  and  the  Lender  shall  continue to deal
   solely  and  directly  with  each  other  in connection with the Lender's and
   Borrower's  rights  and  obligations  under  this  Agreement,  and  (iv) such
   participant's  rights  to  agree or to restrict the Lender's ability to agree
   to  the  modification,  waiver  or  release  of  any  of  the  terms  of  the
   Agreement,  to  consent  to  any action or failure to act by the Borrower, or
   to  exercise  or  refrain  from  exercising  any  powers  or rights which the
   Lender  may  have  under  the  Agreement,  shall  be  limited to the right to
   consent  to  (A)  an  increase  in  the  Commitment,  (B)  a reduction of the
   principal  of,  or  rate or amount of interest on the Loan(s) subject to such
   participation  (other  than  by  the  payment or prepayment thereof), and (C)
   postponement  of  any date fixed for any payment of principal of, or interest
   on, the Loan(s) subject to such participation.

       In addition, Article I, Section 1.1(b) of the RSVP Facility is amended by
   amending and restating the definition of "Commitment" as follows:

       "Commitment"  means  $110  million,  less (i) the amount of loans made by
   the  Lender  to  the  Borrower  for  the  funding of investments made by RSVP
   prior  to  the  spin-off  distribution  of  shares  of  common  stock  of the
   Borrower  by  Reckson  and  (ii)  the  amount  of any investments made by the
   Lender  in  joint  venture investments made with RSVP, and as such amount may
   be reduced from time to time pursuant to Section 2.3.

                                        Very truly yours,
                                        RECKSON OPERATING PARTNERSHIP, L.P.
