Section 20 of the Exchange Act (each, a "Dealer Indemnified Person") against any
losses, claims, damages, liabilities or expenses, joint or several, as the same
are incurred, to which the Dealer Indemnified Person may become subject


                                      -15-

<PAGE>

insofar as such losses, claims, damages, liabilities or expenses (or actions in
respect thereof) (1) arise out of or are based upon an untrue statement or
alleged untrue statement of a material fact contained in the Offering Materials
or any amendment or supplement thereto or arise out of or are based upon the
omission or alleged omission to state in the Offering Materials a material fact
necessary to make the statements therein, in the light of the circumstances
under which they are made, not misleading, other than the Dealer Information
related to such Dealer or (2) are based upon a breach by either of the
Co-Issuers of any of its representations, warranties or agreements contained in
this Agreement, and shall periodically reimburse each Dealer for any and all
legal or other expenses reasonably incurred by such Dealer and each other Dealer
Indemnified Person in connection with investigating or defending, settling,
compromising or paying any such losses, claims, damages, liabilities, expenses
or actions as such expenses are incurred; provided, however, that the foregoing
indemnity with respect to any untrue statement contained in or any statement
omitted from any Offering Materials (as the same may be amended or supplemented)
shall not inure to the benefit of any Dealer (or any Person controlling such
Dealer), if (x) such loss, liability, claim, damage or expense resulted from the
fact that any Dealer sold or placed Notes to a Person to whom there was not sent
or given, at or prior to the written confirmation of such sale or placement, as
the case may be, a copy of the Offering Memorandum, as then amended or
supplemented, (y) the Issuer shall have previously and timely furnished
sufficient copies of the Offering Memorandum, as so amended or supplemented, to
the Dealer in accordance with this Agreement and (z) the Offering Memorandum, as
so amended or supplemented, would have corrected such untrue statement or
omission.

          (b) Each Dealer, severally and not jointly, shall indemnify and hold
harmless the Issuer and the Co-Issuer, each of their respective affiliates,
their respective officers, directors, managers and each person controlling the
Issuer and Co-Issuer within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act, against any losses, claims, damages, liabilities
or expenses, joint or several, as the same are incurred, to which the Issuer or
the Co-Issuer may become subject insofar as such losses, claims, damages,
liabilities or expenses (or actions in respect thereof) arise out of or are
based upon any untrue statement or alleged untrue statement of a material fact
contained in the statements set forth in the Dealer Information with respect to
such Dealer or acts or omissions thereof or arise out of or are based upon the
omission or alleged omission to state in such paragraphs a material fact
necessary with respect to such Dealer or acts or omissions thereof to make the
statements in such paragraphs, in the light of the circumstances under which
they are made, not misleading. For the avoidance of doubt, neither Dealer shall
have any obligation to verify or monitor, or have any liability for, any
statements set forth in the Dealer Information that has not been provided by
such Dealer and any liability of a Dealer arising hereunder shall not affect the
rights or obligations of the other Dealer.

          (c) Promptly after receipt by an indemnified party under Section 8(a)
or (b) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under such subsection, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve it from any liability which it may have to any indemnified party
otherwise under such subsection except to the extent it has been materially
prejudiced by such failure. In case any such action shall be brought against any
indemnified party and it shall notify the indemnifying party of the commencement
thereof, the indemnifying party shall be entitled to participate therein and, to
the extent that it may elect, jointly with any other


                                      -16-

<PAGE>

indemnifying party similarly notified, to assume the defense thereof, with
counsel reasonably satisfactory to such indemnified party; provided, however,
that if the defendants in any such action include both the indemnified party and
the indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party, the indemnified party or parties shall have the right to
select separate counsel to assert such legal defenses and to otherwise
participate in the defense of such action on behalf of such indemnified party or
parties. Upon receipt of notice from the indemnifying party to such indemnified
party of its election so to assume the defense of such action and approval of
counsel by the indemnified party, the indemnifying party shall not be liable to
such indemnified party under this Section 8 for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof unless (i) the indemnified party shall have employed separate counsel in
connection with the assertion of legal defenses in accordance with the proviso
to the immediately preceding sentence (it being understood, however, that the
indemnifying party shall not be liable for the expenses of more than one
separate counsel (in addition to local counsel) for the indemnified party), (ii)
the indemnifying party shall not have employed counsel satisfactory to the
indemnified party at the expense of the indemnifying party to represent the
indemnified party within a reasonable time after notice of commencement of the
action or (iii) the indemnifying party has authorized the employment of counsel
for the indemnified party at the expense of the indemnifying party; and except
that, if clause (i) or (iii) is applicable, such liability shall be only in
respect of the counsel referred to in such clause (i) or (iii).

          (d) If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
Section 8(a) or (b) above in respect of any losses, claims, damages, liabilities
or expenses (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as incurred as a result of such losses, claims, damages,
liabilities or expenses (or actions in respect thereof) in such proportion as is
appropriate to reflect the relative benefits received by the Co-Issuers on the
one hand and the related Dealer on the other from the offering of the Notes. If,
however, the allocation provided by the immediately preceding sentence is not
permitted by applicable law, then each indemnifying party shall contribute to
such amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Co-Issuers on the one hand and the related Dealer on the other in
connection with the statements or omissions or breaches of representations,
warranties or agreements which resulted in such losses, claims, damages,
liabilities or expenses (or actions in respect thereof), as well as any other
relevant equitable considerations. The relative benefits received by the
Co-Issuers on the one hand and by the related Dealer on the other shall be in
the same proportion as the total proceeds to the Co-Issuers from the sale of
Securities bears to, as applicable, the underwriting discounts and commissions
received by Wachovia Securities and Credit Suisse, respectively. The relative
fault shall be determined by reference to, among other things, whether the
indemnified party failed to give the notice required under Section 8(c) above,
including the consequences of such failure, and whether any such untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact relates to information supplied by the Co-Issuers on the
one hand or the related Dealer on the other and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement, omission or breach. The Co-


                                      -17-

<PAGE>

Issuers and each Dealer agree that it would not be just and equitable if
contribution pursuant to this Section 8(d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to above in this Section 8(d). The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages, liabilities or expenses (or actions in respect thereof) referred to
above in this Section 8(d) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim (which shall be limited as
provided in Section 8(c) above if the indemnifying party has assumed the defense
of any such action in accordance with the provisions thereof). Notwithstanding
the provisions of this Section 8(d), no Dealer shall be required to contribute
any amount in excess of the amount by which the amount of the discounts and
commissions received by it or fees paid to it, as applicable, exceeds the amount
of any damages which such Dealer has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation shall be entitled to a
contribution from any person who was not guilty of such fraudulent
misrepresentation.

          9. Duration, Termination and Assignment of this Agreement.

          (a) This Agreement shall become effective as of the date first written
above and shall remain in force until terminated as provided in this Section 9.

without the payment of any penalty by either Dealer, if there is a breach of any
of the representations, warranties, covenants or agreements of the Issuer or the
Co-Issuer hereunder or if any of the conditions set forth in Section 7 hereof
have not been satisfied.

          (c) This Agreement shall terminate in the event that on or after the
date hereof, there shall have occurred any of the following: (i) a suspension or
material limitation in trading in securities generally on the New York Stock
Exchange or in trading of the securities of the Collateral Manager or any
affiliate of the Collateral Manager on any exchange or over-the-counter market;
(ii) a general moratorium on commercial banking activities declared by either
federal or New York State authorities; or (iii) the outbreak or escalation of
hostilities involving the United States or the declaration by the United States
of a national emergency or war, or other calamity or crisis, if the effect of

          Any party hereto may change the address for receipt of communications
by giving written notice to the others.

          11. Consent to Jurisdiction. Each of the parties hereto (i) agrees
that any legal suit, action or proceeding brought by any party to enforce any
rights under or with respect to this Agreement or any other document or the
transactions contemplated hereby or thereby may be instituted in any federal
court in The City of New York, State of New York, U.S.A.; provided, however,
that if a federal court in the City of New York declines jurisdiction for any
reason, any legal suit, action or proceeding brought by any party to enforce any
rights under or with respect to this Agreement or any other document or the
transactions contemplated hereby or thereby may be instituted in any state court
in the City of New York, State of New York, U.S.A., (ii) irrevocably waives to
the fullest extent permitted by law any objection which it may now or hereafter
have to the laying of venue of any such suit, action or proceeding instituted in
the City of New York, State of New York, U.S.A., (iii) irrevocably waives to the
fullest extent permitted by law any claim that and agrees not to claim or plead
in any court that any such action, suit or proceeding brought in a court in the
City of New York, State of New York, U.S.A. has been brought in an inconvenient
forum and (iv) irrevocably submits to the non-exclusive jurisdiction of any such
court in any such suit, action or proceeding or for recognition and enforcement
of any judgment in respect thereof.

          Each of the Issuer and the Co-Issuer hereby irrevocably and
unconditionally designates and appoints CT Corporation System, 111 8th Avenue,
13th Floor, New York, New York 10011, U.S.A. (and any successor entity), as its
authorized agent to receive and forward on its behalf service of any and all
process which may be served in any such suit, action or proceeding in any such
court and agrees that service of process upon CT Corporation shall be deemed in
every respect effective service of process upon it in any such suit, action or
proceeding and shall be taken and held to be valid personal service upon it.
Said designation and appointment shall be irrevocable. Nothing in this Section
11 shall affect the rights of the Dealers, their respective affiliates or any
indemnified party to serve process in any manner permitted by law. Each of the
Issuer and the Co-Issuer further agrees to take any and all action, including
the execution and filing of any and all such documents and instruments, as may
be necessary to continue such designation and appointment of CT Corporation in
full force and effect so long as the Notes are outstanding but in no event for a
period longer than five years from the date of this Agreement. Each of the
Issuer and the Co-Issuer hereby irrevocably and unconditionally authorizes and
directs CT Corporation to accept such service on their behalf. If for any reason
CT Corporation ceases to be available to act as such, each of the Issuer and the
Co-Issuer agrees


                                      -20-

<PAGE>

to designate a new agent in New York City on the terms and for the purposes of
this provision reasonably satisfactory to the Dealers.

          To the extent that either the Issuer or the Co-Issuer has or hereafter
may acquire any immunity from jurisdiction of any court (including, without
limitation, any court in the United States, the State of New York, Cayman
Islands or any political subdivision thereof) or from any legal process (whether
through service of notice, attachment prior to judgment, attachment in aid of
execution, execution or otherwise) with respect to itself or its property or
assets, this Agreement, or any other documents or actions to enforce judgments
in respect of any thereof, it hereby irrevocably waives such immunity, and any
defense based on such immunity, in respect of its obligations under the
above-referenced documents and the transactions contemplated thereby, to the
extent permitted by law.

          12. Arms-Length Transaction. Each of the Co-Issuers acknowledges and
agrees that (i) Wachovia Securities is acting solely in the capacity of an arm's
length contractual counterparty to the Issuer and the Co-Issuer with respect to
the purchase, placement and sale of the Notes pursuant to this Agreement and not
as a financial advisor or a fiduciary to, or agent of, the Issuer or the
Co-Issuer or any other person, (ii) neither Dealer is advising the Issuer, the
Co-Issuer or any other person as to any legal, tax, investment, accounting or
regulatory matters in any jurisdiction, (iii) the Issuer and the Co-Issuer shall
consult with their own advisors concerning any such matter and shall be
responsible for making their own independent investigation and appraisal of any
transactions contemplated by this Agreement, and the Dealers shall have no
responsibility or liability to the Issuer or the Co-Issuer with respect thereto,
and (iv) any review by the Dealers of the Issuer, the Co-Issuer or any
transactions contemplated by this Agreement or any other matters relating
thereto will be performed solely for the benefit of the Dealers and shall not be
on behalf of the Issuer, the Co-Issuer or any other person.

          13. Judgment Currency. If, pursuant to a judgment or order being made
or registered against either the Issuer or the Co-Issuer, any payment under or
in connection with this Agreement to the Dealers is made or satisfied in a
currency (the "Judgment Currency") other than in United States Dollars then, to
the extent that the payment (when converted into United States Dollars at the
rate of exchange on the date of payment or, if it is not practicable for the
Dealers to purchase United States Dollars with the Judgment Currency on the date
of payment, at the rate of exchange as soon thereafter as it is practicable to
do so) actually received by the Dealers falls short of the amount due under the
terms of this Agreement, the Issuer or the Co-Issuer, as applicable, shall, to
the extent permitted by law, as a separate and independent obligation, indemnify
and hold harmless the Dealers against the amount of such short fall and such
indemnity shall continue in full force and effect notwithstanding any such
judgment or order as aforesaid. For the purpose of this Section 13, "rate of
exchange" means the rate at which the Dealers are able on the relevant date to
purchase United States Dollars with the Judgment Currency and shall take into
account any premium and other costs of exchange.

          14. Amendments to this Agreement. This Agreement may be amended by the
parties hereto only if such amendment is specifically approved in writing by the
Issuer, the Co-Issuer and the Dealers. The Co-Issuers must provide notice of any
amendment or modification of this Agreement to each Rating Agency rating the
Notes at the time of any such amendment or modification.

with the internal laws of the State of New York, without giving effect to the
choice of law principles thereof.

          17. Counterparts. This Agreement may be simultaneously executed in

expenses owed to the Dealers hereunder shall remain in full force and effect and
shall survive delivery of and payment for the Securities and any termination of
this Agreement.

          19. No Petition Agreement. Each Dealer agrees that, so long as any
Note is outstanding and for a period of one year plus one day or, if longer, the
applicable preference period then in effect after payment in full of all amounts
payable under or in respect of the Transaction Documents, it shall not institute
against or join or assist any other Person in instituting against, any of the
Issuer or the Co-Issuer any bankruptcy, reorganization, arrangement, insolvency
or liquidation proceedings, or other proceedings under any federal or state
bankruptcy or similar law of any jurisdiction. This Section 19 shall survive any
termination of this Agreement.

          20. Non-Recourse Agreement. Notwithstanding any other provision of
this Agreement, all obligations of the Issuer or the Co-Issuer arising hereunder
or in connection herewith are limited in recourse to the Pledged Obligations and
to the extent the proceeds of the Pledged Obligations, when applied in
accordance with the Priority of Payments, are insufficient to meet the
obligations of the Issuer or the Co-Issuer hereunder in full, the Issuer or the
Co-Issuer, as applicable, shall have no further liability in respect of any such
outstanding obligations and any claims against the Issuer or the Co-Issuer, as
applicable, shall be extinguished and shall not thereafter revive. The Dealers
hereby agree and acknowledge that the obligations of the Co-Issuers hereunder
are solely the corporate obligations of the Co-Issuer and that no recourse shall
be had against any officer, director, employee, shareholder, limited partner or
incorporator of the


                                      -22-

Indenture applicable to the Collateral Manager; the Collateral Manager has full
power and authority to execute, deliver and perform the Collateral Management
