Letter of Credit  Amount,  the  Series  2000-1  Letter of Credit  Provider  will

Credit,  a substitute  letter of credit  substantially  in the form of Exhibit A

Credit but in favor of such successor Trustee.

         (c) If the Lessees  wish to extend the Series  2000-1  Letter of Credit
Expiration  Date for purposes of this  Agreement and the Series 2000-1 Letter of
Credit,  DTAG (on behalf of the Lessees)  shall give the Series 2000-1 Letter of
Credit  Provider and the  Administrative  Agent written notice in the form of an
Issuance  Request (as defined in the Credit  Agreement)  to such effect not more
than 75 days and not less  than 45 days  prior to the date  that is three  years
from the Series  2000-1  Closing  Date (or if such day is not a Business Day (as
defined in the Credit  Agreement) then on the next  succeeding  Business Day (as
defined in the Credit  Agreement))  and thereafter not more than 75 days and not
less than 45 days  prior to each subsequent  one-year anniversary  of the Series

                                       -5-





2000-1 Closing Date, provided, however, that the  additional  term of the Series
2000-1 Letter of Credit may not extend beyond the earlier of (i) two years  from
its date of extension and  (ii) the Commitment  Termination  Date (as defined in
the Credit Agreement) in effect  at the time of  such  extension.  If the Series
2000-1 Letter of Credit Expiration Date is so extended, the Series 2000-1 Letter
of Credit  Provider shall either (i) issue to  the  Trustee in exchange  for and
upon receipt of the then outstanding Series 2000-1 Letter of Credit a substitute
letter of credit having terms identical to  the then  outstanding  Series 2000-1
Letter of Credit  but expiring on the Series  2000-1 Letter of Credit Expiration
Date, as so  extended,  or (ii) deliver  to the Trustee an amendment to the then
outstanding  Series  2000-1 Letter  of Credit to  reflect such  extension of the
Series 2000-1 Letter of Credit Expiration Date.

         (d) If the  conditions  to the extension of the Series 2000-1 Letter of
Credit  Expiration  Date  pursuant to paragraph (c) of this Section 2.1 that are
set  forth in  Section  6.2 of the  Credit  Agreement  and  Section  2.7 of this
Agreement are not satisfied (or waived) on the fortieth day preceding the Series
2000-1  Letter of Credit  Expiration  Date then in effect,  each of the  Lessees
shall use their best efforts to obtain a successor  institution to act as Series
2000-1 Letter of Credit  Provider or, in the  alternative,  to otherwise  credit
enhance the Master Lease payments to be made by the Lessees with (1) the funding
of the Series  2000-1  Cash  Collateral  Account  with cash in the amount of the
Series 2000-1 Letter of Credit Amount  immediately prior to any drawing referred
to in subsection (f) below (whether funded from an LOC Termination  Disbursement
or otherwise),  (2) other cash  collateral  accounts,  overcollateralization  or
subordinated  securities or (3) with the written consent of each Managing Agent,
a surety bond or other similar  arrangements;  provided,  however, that any such
successor institution or other form of substitute credit enhancement referred to
in the  foregoing  clauses  (2) and (3)  shall  be  subject  to (x) the  written
approval of each Managing  Agent if the ratings with respect to such  substitute
credit  enhancement,  if applicable,  are less than "A-1" or the equivalent from
S&P, "P-1" or the equivalent from Moody's;  provided further, however, that only
after all  amounts  then owing to the Series  2000-1  Letter of Credit  Provider
hereunder  have been  paid in full  shall  the  letter of credit  issued by such
successor  bank  or  banks  or  such  other  substitute  credit  enhancement  be
substituted  for the  Series  2000-1  Letter  of  Credit.  If  such a  successor
institution or such other substitute credit enhancement is obtained, each of the
Lessees  and, if  applicable,  such  successor  institution  shall (i) sign such
documents and  instruments  as shall be  appropriate  to evidence such successor
institution's issuance of a substitute letter of credit or such other substitute
credit enhancement, (ii) cause the Trustee to return to the Series 2000-1 Letter
of Credit Provider the then outstanding Series 2000-1 Letter of Credit and (iii)
deliver to the Trustee a substitute  letter of credit having terms  identical to
the then  outstanding  Series 2000-1 Letter of Credit but expiring on the Series
2000-1 Letter of Credit  Expiration  Date as so extended and with such successor
institution  as the  issuer  thereof or deliver  such  other  substitute  credit
enhancement.

         (e) If (i)  DTAG  (on  behalf  of the  Lessees)  does  not  request  an
extension  of the Series  2000-1  Letter of Credit  Expiration  Date or (ii) the
conditions  precedent  to the  extension of the Series  2000-1  Letter of Credit
Expiration  Date pursuant to paragraph (c) of this Section 2.1 are not satisfied
(or waived) and the Lessees do not obtain a successor  Series  2000-1  Letter of
Credit Provider or other substitute  credit  enhancement prior to the date which
is 30 days prior to the Series 2000-1  Letter of Credit  Expiration  Date,  then
DTAG (on behalf of the Lessees) shall immediately notify the Trustee in writing,

                                       -6-





and the Trustee, pursuant to Section  4.16  of  the  Series  2000-1  Supplement,
shall immediately  request a LOC  Termination  Disbursement  in accordance  with
Section 4.16  of the Series  2000-1 Supplement  no later  than one  Business Day
prior to such Series 2000-1 Letter of Credit  Expiration Date in an amount equal
to the Series 2000-1 Letter of Credit Amount.  The Trustee shall,  in accordance
with Sections 4.16 and 4.17 of the Series 2000-1 Supplement,  deposit the amount
of such LOC  Termination  Disbursement  in the  Series  2000-1  Cash  Collateral
Account and shall use such funds in the same manner as the Series  2000-1 Letter
of Credit would be used hereunder.

         (f) If (i) the  short-term  debt or deposit rating of the Series 2000-1
Letter of Credit Provider shall be downgraded  below "A-1" by S&P or below "P-1"
by Moody's or (ii) the Series 2000-1 Letter of Credit Provider has notified DTAG
(and has not retracted such  notification)  that its compliance  with any of its
obligations hereunder would be unlawful,  each of the Lessees shall use its best
efforts to obtain a  successor  institution  to act as Series  2000-1  Letter of
Credit Provider or, in the  alternative,  to otherwise credit enhance the Master
Lease  payments  to be made by the  Lessees  with (1) the  funding of the Series
2000-1  Cash  Collateral  Account  with cash in the amount of the Series  2000-1
Letter of Credit Amount (whether funded from an LOC Termination  Disbursement or
otherwise),  (2)  other  cash  collateral  accounts,   overcollateralization  or
subordinated securities or (3) with the consent of each Managing Agent, a surety
bond or  other  similar  arrangements;  provided,  however,  that  (x) any  such
successor institution or such other substitute credit enhancement referred to in
the foregoing  clauses (2) and (3) shall be approved by each Managing Agent, and
(y) only after all  amounts  then owing to the  Series  2000-1  Letter of Credit
Provider  hereunder  have been paid in full shall the letter of credit issued by
such  successor  bank or banks or such other  substitute  credit  enhancement be
substituted  for the  Series  2000-1  Letter of  Credit.  If the  Lessees do not
replace the Series  2000-1  Letter of Credit  Provider  within 60 days after the
occurrence  of any of the  events  specified  in  subclause  (i) or (ii) of this
clause (e),  then DTAG (on behalf of the  Lessees)  shall  notify the Trustee in
writing,  and  the  Trustee,  pursuant  to  Section  4.16 of the  Series  2000-1
Supplement,  shall  immediately  request  an  LOC  Termination  Disbursement  in
accordance with Sections 4.16 of the Series 2000-1 Supplement in an amount equal
to the Series 2000-1 Letter of Credit Amount.  The Trustee shall,  in accordance
with Sections 4.16 and 4.17 of the Series 2000-1 Supplement,  deposit the amount
of such LOC  Termination  Disbursement  into the Series  2000-1 Cash  Collateral
Account and shall use such funds in the same manner as the Series  2000-1 Letter
of Credit would be used hereunder.

         (g) In the event that (i) the Series 2000-1  Letter of Credit  Provider
shall have notified DTAG (and shall not have retracted such  notification)  that
its compliance with any of its obligations hereunder or under the related Series
2000-1  Letter of Credit would be  unlawful,  (ii) the Series  2000-1  Letter of
Credit  Provider  fails to extend its Series 2000-1 Letter of Credit  Expiration
Date  pursuant to Section  2.1(c),  (iii) any of the Lessees or DTAG is required
pursuant to Sections  5.1,  5.3, 5.5 or 5.6 of the Credit  Agreement to make any
payment to or on behalf of the Series 2000-1 Letter of Credit Provider (or would
be so  required  on or  prior  to the next  following  date on  which a  payment
hereunder  is  required to be made to or for any such  Series  2000-1  Letter of
Credit  Provider),  (iv) the Series 2000-1 Letter of Credit  Provider shall have
wrongfully failed to fund any LOC Credit  Disbursement when required  hereunder,
or (v) the  short-term  debt or deposit  rating of the Series  2000-1  Letter of
Credit  Provider  shall  be  downgraded  below "A-1"  by S&P  or below  "P-1" by

                                       -7-





Moody's, then the Lessees shall have the right at their own expense, upon notice
to the Series 2000-1 Letter of Credit Provider, and such Series 2000-1 Letter of
Credit  Provider hereby  agrees,  to transfer  and assign  without recourse  (in
accordance  with and subject to the  restrictions  contained in Section 4.9 with
respect to assignments) all the interests,  rights and obligations of the Series
2000-1 Letter of Credit Provider to a replacement Series 2000-1 Letter of Credit
Provider  (having a short-term  debt or deposit  rating of at least "A-1" by S&P
and "P-1" by  Moody's)  provided by DTAG (on behalf of the  Lessees);  provided,
however,  that (w) no such assignment to any replacement Series 2000-1 Letter of
Credit  Provider shall  conflict with any law, rule,  regulation or order of any
Governmental  Authority,  (x) such assignment to any  replacement  Series 2000-1
Letter of Credit Provider shall be without recourse, representation and warranty
and shall be on terms  and  conditions  reasonably  satisfactory  to the  Series
2000-1 Letter of Credit  Provider and such  replacement  Series 2000-1 Letter of
Credit Provider,  (y) the purchase price paid by such replacement  Series 2000-1
Letter of Credit Provider shall be in an amount equal to the aggregate amount of
the LOC Credit Disbursements owed by the Lessees or DTAG to such replaced Series
2000-1  Letter of Credit  Provider  under this  Agreement as of the date of such
assignment,  and (z) DTAG (on behalf of the Lessees) or such replacement  Series
2000-1 Letter of Credit Provider, as the case may be, shall pay to such replaced
Series  2000-1  Letter of Credit  Provider in same day funds on the date of such
assignment  the principal of and interest  accrued to the date of payment on the
LOC Credit  Disbursements or LOC Termination  Disbursement made by such replaced
Series 2000-1 Letter of Credit Provider  hereunder and all other amounts accrued
for such replaced Series 2000-1 Letter of Credit  Provider's  account or owed to
it  hereunder,  including  those  amounts  owed  pursuant to Section 2.4 of this
Agreement and Sections 5.1, 5.3, 5.5 and 5.6 of the Credit  Agreement (which are
incorporated  herein);  provided further,  however,  that only after all amounts
then  owing to the  Series  2000-1  Letter of  Credit  Provider  to be  replaced
hereunder have been paid in full shall the Series 2000-1 Letter of Credit issued
by the  replacement  Series 2000-1 Letter of Credit  Provider be substituted for
the Series 2000-1 Letter of Credit Provider's Series 2000-1 Letter of Credit. If
such a  replacement  Series  2000-1  Letter of Credit is  obtained,  each of the
Lessees  and,  if  applicable,  such  successor  institution,  shall  sign  such
documents and  instruments  as shall be  appropriate  to evidence such successor
institution's issuance of a substitute letter of credit or such other substitute
credit  enhancement.  If a replacement  Series 2000-1 Letter of Credit  Provider
succeeds the Series 2000-1 Letter of Credit Provider or other substitute  credit
enhancement is obtained to replace the Series 2000-1 Letter of Credit,  then the
Lessees and, if  applicable,  such  successor  institution,  shall (a) sign such
documents and  instruments  as shall be  appropriate  to evidence such successor
institution's issuance of a substitute letter of credit or such other substitute
credit  enhancement,  (b) cause the return to the Series 2000-1 Letter of Credit
Provider of the then outstanding Series 2000-1 Letter of Credit, and (c) deliver
to the Trustee a substitute  letter of credit having terms identical to the then
outstanding  Series 2000-1 Letter of Credit but with such successor  institution
as the issuer thereof or deliver such other substitute credit enhancement.  DTAG
shall provide prompt written notice to each Managing Agent of the appointment of
any such successor institution in accordance with the terms of this Agreement.

shall make an LOC Termination Disbursement at the time, in the manner and to the
account specified in the Series 2000-1 Letter of Credit.

         Section 2.3 Reimbursement.  (a) Each Lessee agrees to pay to the Series
2000-1 Letter of Credit  Provider on demand (which demand may be made on DTAG on
behalf of the Lessees) on and after each date on which the Series  2000-1 Letter
of Credit Provider shall pay any LOC Credit Disbursement under the Series 2000-1
Letter of Credit in respect of Series 2000-1 Lease Payment  Losses  allocated to

Provider),  plus (B) interest on any amount  remaining  unpaid by such Lessee to
the Series 2000-1 Letter of Credit  Provider  under clause (A) above,  from (and
including)  the date such amount is paid by the Series  2000-1  Letter of Credit

                           Disbursement that is allocable,  as determined by the
                           Trustee or, in the absence of such determination, the

                           due and payable by such Lessee under the Master Lease

                           which in the  aggregate for all such Lessees is equal
                           to 100%;

                           such Lessee  from the  date of  payment  of such  LOC
                           Termination Disbursement by the  Series 2000-1 Letter
                           of  Credit   Provider  until   payment  in   full  of
                           the Lessee  Termination  Reimbursement Share  by such
                           Lessee to the Series 2000-1 Letter of Credit Provider

made under  Section  2.1(e) or (f) and shall be entitled to receive the earnings
thereon when such earnings are realized (the term "earnings" to include interest
payable  by each  Lessee  on  amounts  withdrawn  from the  Series  2000-1  Cash
Collateral  Account)  from such  investments  from time to time from the  Series
2000-1 Cash Collateral  Account in accordance with the following  subsection (d)
and  Sections   4.17(c)  and  (d)  of  the  Series  2000-1   Supplement.   After

interests may appear),  may direct  investment in Permitted  Investments  of the
funds on deposit in the  Series  2000-1  Cash  Collateral  Account  and shall be

the extent accruing on the amount of an LOC Termination  Disbursement made under
Section  2.1(e) or (f) until the earlier of the date the Series 2000-1 Letter of
Credit  Provider is reimbursed  for such amount or the date  interest  begins to
accrue on the full amount of such LOC Termination  Disbursement  and then to the
related Lessee.  Any amounts (other than earnings on investments)  released from
the Series 2000-1 Cash Collateral  Account in accordance with Section 4.17(d) of
the Series 2000-1 Supplement shall be paid to the Series 2000-1 Letter of Credit
Provider to the extent the Series 2000-1 Letter of Credit  Provider has not been
fully  reimbursed  by the Lessees  under  clauses (a), (b) and (c) above for LOC
Credit  Disbursements or a LOC Termination  Disbursement.  Upon reimbursement in

clauses (a), (b) and (c) above,  amounts  released  from the Series  2000-1 Cash

reimbursed  to the Series  2000-1 Cash  Collateral  Account in  accordance  with
Section 4.7 of the Series 2000-1 Supplement.

the Series 2000-1 Letter of Credit  Provider in connection  with issuance of the
Series 2000-1 Letter of Credit including,  without limitation,  Sections 3.3 and

and expenses pursuant to and in the manner provided in the Credit Agreement.

         Section 2.5 No Liability of Series  2000-1  Letter of Credit  Provider.
Each of the Lessees and DTAG each  acknowledges that the Series 2000-1 Letter of
Credit  Provider is not  responsible  for any risks of acts or  omissions of the
Trustee and any other  beneficiary  or transferee of the Series 2000-1 Letter of
Credit with respect to its use of the Series  2000-1  Letter of Credit.  Neither
the Series 2000-1 Letter of Credit Provider nor any of its respective employees,
officers or directors shall be liable or responsible  for: (a) the use which may

documents  which do not  comply  with the terms of the Series  2000-1  Letter of

reference to the Series 2000-1 Letter of Credit; or (d) any other  circumstances
whatsoever  in making or failing to make payment  under the Series 2000-1 Letter
of Credit;  provided,  however, that the Series 2000-1 Letter of Credit Provider
shall be  liable to each  Lessee to the  extent of any  direct,  as  opposed  to
consequential,  damages  suffered  by such  Lessee  which were caused by (i) the
Series 2000-1 Letter of Credit Provider's willful misconduct or gross negligence
in determining  whether  documents  presented  under the Series 2000-1 Letter of
Credit  comply with the terms of the Series  2000-1 Letter of Credit or (ii) the
Series 2000-1 Letter of Credit Provider's gross negligence in failing to make or
willful  failure to make lawful payment under the Series 2000-1 Letter of Credit
after the  presentation  to the Series 2000-1  Letter of Credit  Provider by the
Trustee of a certificate strictly complying with the terms and conditions of the
Series  2000-1  Letter of Credit.  In  furtherance  and not in limitation of the
foregoing, the Series 2000-1 Letter of Credit Provider may accept documents that
appear  on  their  face  to be in  order,  without  responsibility  for  further
investigation.

         Section 2.6 Surrender of Series 2000-1 Letter of Credit.  Provided that
the Series  2000-1  Letter of Credit  Provider is not then in default  under the
Series  2000-1  Letter of Credit by reason of its  having  wrongfully  failed to
honor a demand  for  payment  previously  made by the  Trustee  under the Series
2000-1  Letter of Credit,  the Series  2000-1  Letter of Credit  Provider  shall
instruct  the Trustee to  surrender  the Series  2000-1  Letter of Credit to the
Series 2000-1 Letter of Credit Provider on the earliest of (i) the Series 2000-1
Letter of Credit  Expiration  Date,  (ii) the date on which  the  Series  2000-1
Letter of Credit Provider  honors a Certificate of  Termination Demand presented

                                      -11-





under the  Series 2000-1  Letter of Credit  to the extent  of the Series  2000-1
Letter of Credit  Amount as in effect on such date,  and (iii) the date on which

deemed to have been so paid or disbursed by the Series  2000-1  Letter of Credit
Provider  as if a demand  had been made by the  Series  2000-1  Letter of Credit
Provider to the Lessees  under Section 2.3 hereof and any amounts so received by

         Section 4.6 Waivers, etc. Neither any failure nor any delay on the part
of the Series 2000-1 Letter of Credit Provider in exercising any right, power or
privilege  hereunder  or under the Series  2000-1  Letter of Credit or any other
Related  Document  shall  operate  as a waiver  thereof,  nor  shall a single or

                                      -27-





         Section 4.7  Severability.  Any provisions of this Agreement  which are
prohibited or unenforceable in any jurisdiction  shall, as to such jurisdiction,
be ineffective to the extent of such  prohibition  or  unenforceability  without
invalidating  the  remaining  provisions  hereof  and any  such  prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable such provision in any other jurisdiction.

         Section 4.8 Term.  This Agreement shall remain in full force and effect
until the  reimbursement of all LOC Disbursements by the Lessees or DTAG, as the
case may be, and the payment by the Lessees or DTAG,  as the case may be, of all
other amounts payable hereunder,  notwithstanding the earlier termination of the
Series 2000-1 Letter of Credit.

         Section 4.9  Successors and Assigns.  This  Agreement  shall be binding
upon the Series 2000-1 Letter of Credit Provider and its successors and assigns,
each Lessee and its successors and assigns,  DTAG and its successors and assigns
and RCFC and its  successors  and assigns;  provided,  however,  that the Series
2000-1 Letter of Credit  Provider may at any time (i) assign all or a portion of
its  obligations  under the Series  2000-1 Letter of Credit and its rights under
this Agreement to an Eligible Credit Enhancer;  provided further,  however, that
(x) each of DTAG and each Managing Agent shall have consented in writing to such
assignment  (which  consent shall not be  unreasonably  withheld),  and (y) such
assignment  shall be for an amount at least equal to  $5,000,000,  or (ii) grant
participations  to any other Person, in all or part of its obligations under the
Series  2000-1  Letter of Credit and its rights under this  Agreement  (it being
understood  and agreed that the Lessees shall have no obligation to give notices
to any such participant,  that such participation will not in any way reduce the
Series 2000-1 Letter of Credit  Provider's  commitment to make LOC Disbursements
hereunder,  and that such  participation  (other than a participation  held by a
Revolving  Lender  pursuant  to the Credit  Agreement)  shall not  increase  the
obligations  (including  with  respect  to costs and  expenses)  of the  Lessees
hereunder);  provided that the Series 2000-1 Letter of Credit  Provider shall be
entitled  to  receive  any  increased  costs or  indemnities  payable  hereunder
incurred by the Series 2000-1 Letter of Credit  Provider or such  participant to
the  extent  not in  excess  of such  amounts  calculated  as if  there  were no
participation.  The Series 2000-1 Letter of Credit Provider hereby  acknowledges
and agrees that any such  disposition will not alter or affect the Series 2000-1
Letter of Credit Provider's direct obligations to the Trustee,  and that none of
the Lessees,  DTAG or RCFC shall have any obligations to have any  communication
or relationship with any participant in order to enforce such obligations of the
Series  2000-1 Letter of Credit  Provider  hereunder and under the Series 2000-1
Letter of Credit.  All  agreements,  representations  and warranties made herein
shall survive the execution and delivery of this Agreement.

         Section 4.10 Counterparts. This Agreement may be executed in any number
of  counterparts,  and by the different  parties  hereto on the same or separate
counterparts,  each of which counterparts, when so executed and delivered, shall
be deemed to be an original and all of which counterparts, taken together, shall
constitute one and the same agreement.

         Section 4.11 Further Assurances.  The Lessees, DTAG and RCFC each agree
to do such  further  acts and things and to  execute  and  deliver to the Series
2000-1 Letter of Credit Provider such additional assignments, agreements, powers
and instruments as are reasonably required by the Series 2000-1 Letter of Credit

                                      -28-




Provider to  carry into  effect  the purposes  of this  Agreement  and under the
Related Documents or to better assure and confirm to the Series 2000-1 Letter of
Credit Provider its rights,  powers and remedies hereunder and under the Related
Documents.

         Section  4.12  Survival  of   Representations   and   Warranties.   All
representations and warranties  contained herein or made in writing by DTAG, the
Lessees and RCFC in connection herewith shall survive the execution and delivery
of this  Agreement,  regardless of any  investigation  made by the Series 2000-1
Letter of Credit  Provider  or on its behalf and shall  continue  so long as and
until such time as all  obligations  hereunder shall have been paid in full. The
obligations  of the Lessees  under  Sections 2.5, 4.1, 4.2 and 4.3 shall in each
case  survive  any  termination  of this  Agreement,  the payment in full of all
obligations hereunder or under any other Related Document and the termination of
the Series 2000-1 Letter of Credit.

         Section 4.13  Obligation.  Each of the Series  2000-1  Letter of Credit
Provider and each of the Lessees  understands  and agrees that the Series 2000-1
Letter of Credit is irrevocable  and the obligations of the Series 2000-1 Letter
of  Credit  Provider  as  issuer  thereof  shall be  unaffected  by any  default
hereunder,  including, without limitation any failure to pay the amounts due and
payable to the Series  2000-1  Letter of Credit  Provider  under Section 2.4. No
failure of any of the  Lessees (or any person or  organization  acting on behalf
thereof)  or the  Trustee  to take any action  (whether  required  hereunder  or
otherwise),  nor any action taken by any of the Lessees shall be asserted by the
Series 2000-1 Letter of Credit Provider as a defense to payment under the Series
2000-1  Letter of Credit  (except  for the  failure of any  documents  presented
thereunder to comply with the terms of the Series 2000-1 Letter of Credit) or as
the basis of a right of set off by the Series 2000-1  Letter of Credit  Provider
against its obligations to make any such payment.

         Section 4.14 Headings.  Section headings in this Agreement are included
herein for convenience of reference only and shall not constitute a part of this
Agreement for any other purpose.

         Section  4.15  Confidentiality.  The  Series  2000-1  Letter  of Credit
Provider  agrees that it shall not disclose  any  Confidential  Information  (as
defined  below) to any Person  without the consent of DTAG, the Lessees or RCFC,
as applicable,  other than (a) to the Series 2000-1 Letter of Credit  Provider's
Affiliates and to the  Administrative  Agent and the Revolving Lenders and their
respective officers, directors,  employees, agents and advisors and to actual or

(b) as required by any law, rule or  regulation  or judicial  process and (c) as
requested  or required by any state,  federal or foreign  authority  or examiner
regulating banks or banking.

         "Confidential  Information" means information that DTAG, the Lessees or
RCFC furnishes to the Series 2000-1 Letter of Credit  Provider on a confidential
basis, but does not include any such  information  that is or becomes  generally

         Section 4.16 Additional Series 2000-1 Letter of Credit  Providers.  The
Series 2000-1 Letter of Credit Provider acknowledges and agrees that the Lessees
may obtain Series 2000-1 Letter of Credit Provider  commitments  from additional
Series  2000-1  Letter of Credit  Providers  from  time to time,  provided  such
commitments  are, unless the Series 2000-1 Letter of Credit  Provider  otherwise
consents,  on the same terms and  provisions  as this  Agreement and provide for
obligations that rank pari passu with each Lessee's obligations hereunder.

         Section  4.17  Additional  Subsidiary  Lessees.  Any direct or indirect
Subsidiary of DTAG (each a "DTAG  Subsidiary")  shall have the right to become a
"Lessee" under and pursuant to the terms of this Agreement by complying with the
provisions  of  Section  28.1 of the  Master  Lease and the  provisions  of this
Section 4.17. In the event a DTAG  Subsidiary  desires to become  "Lessee" under
this Agreement,  then the Guarantor and such DTAG  Subsidiary  shall execute and
deliver to the Series 2000-1 Letter of Credit Provider and the Trustee:

         (i) an Affiliate  Joinder in Enhancement  Letter of Credit  Application
and  Agreement in the form  attached  hereto as Exhibit B (each,  an  "Affiliate
Joinder in Enhancement Letter of Credit Application and Agreement");

         (ii) copies of the  documentation set forth  in clauses (a) through (j)
of Section 28.1 of the Master Lease;

         (iii) an Officers'  Certificate  and an opinion of counsel each stating
that the joinder described in clause (i) above by such DTAG Subsidiary  complies
with this Section 4.17 and that all  conditions  precedent  herein  provided for
relating to such transaction have been complied with; and

         (iv) any  additional  documentation  that the Series  2000-1  Letter of
Credit Provider or the Trustee may reasonably require to evidence the assumption
by such DTAG  Subsidiary of the  obligations  and  liabilities set forth in this
Agreement.

Upon satisfaction of the foregoing conditions and receipt by each of the Trustee
and the Series 2000-1 Letter of Credit  Provider of original  executed copies of
the applicable Affiliate Joinder in Enhancement Letter of Credit Application and
Agreement  executed  by such  DTAG  Subsidiary  and  the  Guarantor,  such  DTAG
Subsidiary  shall for all  purposes be deemed to be a "Lessee"  for  purposes of
this  Agreement  and  shall be  entitled  to the  benefits  and  subject  to the
liabilities and obligations of a Lessee hereunder.

         Section 4.18  Enhancement  Letter of Credit  Application and Agreement.
This  Agreement is a  Enhancement  Letter of Credit  Application  and  Agreement
executed pursuant to the Credit  Agreement.  In the event that, after construing
the terms of this Agreement and the Credit Agreement in a manner that would seek
to avoid any  purported  inconsistency  or  conflict  between  the terms of this
Agreement,  on the one hand, and the terms of the Credit Agreement, on the other
hand,  such  inconsistency  or  conflict  cannot be  avoided,  the terms of this
Agreement shall control.

         Section 4.19 Series  2000-1  Letter of Credit  Provider as  Enhancement
Provider and  Third-Party  Beneficiary.  The Lessees,  RCFC and DTAG each hereby
acknowledges  and agrees that the Series 2000-1 Letter of Credit Provider is (i)
an "Enhancement  Provider" (as such term is used in the Base Indenture) and (ii)
without  limiting  the  effect  of any  other  provision  contained  in the Base
Indenture or the Series  2000-1  Supplement,  a third-party  beneficiary  of the
provisions  set forth in Article 11 of the Base Indenture and Section 8.6 of the
Series 2000-1 Supplement.

         Section 4.20  No Recourse; No Petition.  (a) Each of the parties hereto
hereby covenants and agrees that:

                  (i) no  recourse  shall be had for the  payment  of any amount
         owing in respect of any  disbursement  made under this Agreement or the
         Series  2000-1 Letter of Credit or for the payment of any fee hereunder
         or thereunder or any other  obligation or claim arising out of or based
         upon this  Agreement or the Series 2000-1 Letter of Credit against RCFC
         or any stockholder, employee, officer, director or incorporator of RCFC
         based on their status as such or their actions in connection therewith;
         and

                  (ii) prior to the date which is one year and one day after the
         payment in full of any Series  2000-1 Notes issued by RCFC  pursuant to
         the Indenture,  such party will not institute against, or join with any
         other   Person  in   instituting   against,   RCFC,   any   bankruptcy,
         reorganization,  arrangement, insolvency or liquidation proceedings, or
         other proceedings under any Federal or state bankruptcy or similar law,
         all as more  particularly  set  forth  in  Section  12.16  of the  Base
         Indenture  and  subject to any  retained  rights set forth  therein (it
         being  agreed  and  understood  that  nothing  contained  herein  shall
         preclude participation by any such party in assertion or defense of its
         claims in any such proceeding involving RCFC);

provided,  however, that nothing in this clause (a) shall constitute a waiver of
any right to  indemnification,  reimbursement or other payment from RCFC to such
party pursuant to any Related Document (other than this Agreement) to which RCFC
is a party.

         (b) In the event  that any such  party  takes  action in  violation  of
clause  (a)(ii),  RCFC agrees  that it shall file an answer with the  bankruptcy
court or otherwise  properly contest the filing of such a petition by such party
against RCFC or the  commencement of such action and raise the defense that such
Person has agreed in writing not to take such action and should be estopped  and
precluded therefrom and such other defenses, if any, as its counsel advises that
it may assert.

         (c) The  provisions of this Section 4.20 shall survive the  termination
of this Agreement.

                                      -31-




         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be

                                       -1-





being the "Series  2000-1 Letter of  Credit Provider's  Office") on December 14,
2003 (or, if such date is not a Business Day (as defined below), the immediately
preceding Business Day) (the "Scheduled Letter of Credit Expiration  Date"). You
are referred to herein (and in each Annex hereto) as the Trustee.

         The Series 2000-1 Letter of Credit Provider irrevocably  authorizes you
to draw on it, in accordance  with the terms and  conditions  and subject to the
reductions in amount as  hereinafter  set forth,  (1) in one or more drawings by
one or more of the Trustee's  drafts,  each drawn on the Series 2000-1 Letter of
Credit Provider at the Series 2000-1 Letter of Credit Provider's Office, payable
at sight on a Business Day (as defined below),  and accompanied by the Trustee's
written  and  completed  certificate  purported  to be signed by the  Trustee in
substantially the form of Annex A attached hereto (any such draft accompanied by
such certificate being a "Credit Demand"), an amount equal to the face amount of
each such draft but in the  aggregate  amount not  exceeding  the Series  2000-1
Letter of Credit  Amount as in effect on such  Business  Day and (2) in a single
drawing by the  Trustee's  draft,  drawn on the Series  2000-1  Letter of Credit
Provider at the Series 2000-1  Letter of Credit  Provider's  Office,  payable at

may be made hereunder.  Any Credit Demand or Termination Demand may be delivered
by  facsimile  transmission  to the Series  2000-1  Letter of Credit  Provider's
Office. "Business Day" means any day other than a Saturday,  Sunday or other day
on which banks are required or authorized by law to close in New York City,  New
York.  Upon the Series  2000-1  Letter of Credit  Provider  honoring  any Credit
Demand  presented  hereunder,  the Series  2000-1  Letter of Credit Amount shall
automatically  be  decreased  by an amount  equal to the  amount of such  Credit
Demand.  In addition to the  foregoing  reduction,  the Series  2000-1 Letter of
Credit  Amount  shall  automatically  be reduced to zero and this Series  2000-1
Letter of Credit shall be  terminated  upon the Series  2000-1  Letter of Credit
Provider honoring any Termination Demand presented to it hereunder.

         The  Series  2000-1  Letter of  Credit  Amount  shall be  automatically
reinstated  with respect to  reimbursement  of any Credit Demand when and to the
extent,  but only when and to the extent,  that (i) the Series  2000-1 Letter of
Credit Provider is reimbursed by any of the Lessees or DTAG (on behalf of any of
