                 -------------------------------------------------------
Security. Financial Security represents, warrants and agrees as follows:
--------

          (a)  Organization, Etc. Financial Security is a stock insurance
               -----------------
     company duly organized, validly existing and authorized to transact
     financial guaranty insurance business under the laws of the State of New
     York.

          (b)  Authorization, Etc. The Policy and the Financial Security
               ------------------
     Agreements have been duly authorized, executed and delivered by Financial
     Security.

          (c)  Validity, Etc. The Policy and the Financial Security Agreements
               -------------
     constitute valid and binding obligations of Financial Security, enforceable
     against Financial Security in accordance with their terms, subject, as to
     the enforcement of remedies, to bankruptcy, insolvency, reorganization,
     rehabilitation, moratorium and other similar laws affecting the
     enforceability of creditors' rights generally applicable in the event of
     the bankruptcy or insolvency of Financial Security and to the application
     of general principles of equity and subject, in the case of this Agreement,
     to principles of public policy limiting the right to enforce the
     indemnification provisions contained herein.

          (d)  Exemption From Registration. The Policy is exempt from
               ---------------------------
     registration under the Securities Act.

          (e)  No Conflicts. Neither the execution or delivery by Financial
               ------------
     Security of the Policy or the Financial Security Agreements, nor the
     performance by Financial Security of its obligations thereunder, will
     conflict with any provision of the certificate of incorporation or the
     bylaws of Financial Security nor result in a breach of, or constitute a
     default under, any material agreement or other instrument to which
     Financial Security is a party or by which any of its property is bound nor
     violate any judgment, order or decree applicable to Financial Security of
     any governmental or regulatory body, administrative agency, court or
     arbitrator having jurisdiction over Financial Security (except that, in the
     published opinion of the Securities and Exchange Commission, the
     indemnification provisions of this Agreement, insofar as they relate to
     indemnification for liabilities arising under the Securities Act, are
     against public policy as expressed in the Securities Act and are therefore
     unenforceable).

                                       3
<PAGE>

          (f)  Financial Information. The consolidated balance sheets of
               ---------------------
     Financial Security as of December 31, 1999 and December 31, 1998 and the
     related consolidated statements of income, changes in shareholder's equity
     and cash flows for the fiscal years then ended, and the interim
     consolidated balance sheet of Financial Security as of March 31, 2000, and
     the related statements of income, changes in shareholder equity and cash
     flows for the interim period then ended, which are incorporated by
     reference in the Prospectus, fairly present in all material respects the
     financial condition of Financial Security as of such dates and for such
     periods in accordance with generally accepted accounting principles
     consistently applied (subject as to interim statements to normal year-end
     adjustments) and since the date of the most current interim consolidated
     balance sheet referred to above there has been no change in the financial
     condition of Financial Security which would materially and adversely affect
     its ability to perform its obligations under the Policy.

          (g)  Financial Security Information. The information in the Prospectus
               ------------------------------
     Supplement set forth under the caption "The Insurer" (as revised from time
     to time in accordance with the provisions hereof, the "Financial Security
                                                            ------------------
     Information") is limited and does not purport to provide the scope of
     -----------
     disclosure required to be included in a prospectus with respect to a
     registrant in connection with the offer and sale of securities of such
     registrant registered under the Securities Act. Within such limited scope
     of disclosure, however, as of the date of the Prospectus Supplement and as
     of the date hereof, the Financial Security Information does not contain any
     untrue statement of a material fact, or omit to state a material fact
     necessary to make the statements contained therein, in the light of the
     circumstances under which they were made, not misleading.

          (h)  Additional Information.  Financial Security will furnish to the
               ----------------------
     Underwriters or the Seller, upon request of the Underwriters or the Seller,
     as the case may be, copies of Financial Security's most recent financial
     statements (annual or interim, as the case may be) which fairly present in
     all material respects the financial condition of Financial Security as of
     the dates and for the periods indicated, in accordance with generally
     accepted accounting principles consistently applied except as noted therein
     (subject, as to interim statements, to normal year-end adjustments).  In
     addition, if the delivery of a Prospectus relating to the Securities is
     required at any time prior to the expiration of nine months after the time
     of issue of the Prospectus in connection with the offering or sale of the
     Securities, the Seller or the Underwriters will notify Financial Security
     of such requirement to deliver a Prospectus and Financial Security will
     promptly provide the Underwriters and the Seller with any revisions to the
     Financial Security Information that are in the judgment of Financial
     Security necessary to prepare an amended Prospectus or a supplement to the
     Prospectus.

          (i)  Opinion of Counsel. Financial Security will furnish to the
               ------------------
     Underwriters and the Seller on the closing date for the sale of the
     Securities an opinion of its Assistant General Counsel, to the effect set
     forth in Exhibit A attached hereto, dated such closing date and addressed
     to the Seller and the Underwriters.

          (j)  Consents and Reports of Independent Accountants. Financial
               -----------------------------------------------
     Security will furnish to the Underwriters and the Seller, upon request, as
     comfort from its

                                       4
<PAGE>

     independent accountants in respect of its financial condition, (i) at the
     expense of the Person specified in the Insurance Agreement, a copy of the
     Prospectus, including either a manually signed consent or a manually signed
     report of Financial Security's independent accountants and (ii) the
     quarterly review letter by Financial Security's independent accountants in
     respect of the most recent interim financial statements of Financial
     Security.

Nothing in this Agreement shall be construed as a representation or warranty by
Financial Security concerning the rating of its insurance financial strength by
Moody's Investors Service, Inc., its insurer financial strength by Standard &
Poor's Ratings Services and Standard & Poor's (Australia) Pty. Ltd., its claims-
paying ability by Fitch IBCA, Inc. and Japan Rating and Investment Information,
Inc. or any other rating assigned by a rating agency (collectively, the "Rating
                                                                         ------
Agencies").  The Rating Agencies, in assigning such ratings, take into account
--------
facts and assumptions not described in the Prospectus and the facts and
assumptions which are considered by the Rating Agencies, and the ratings issued
thereby, are subject to change over time.

     Section 3. Representations, Warranties and Agreements of the Underwriters.
                --------------------------------------------------------------
Each of the Underwriters represents, warrants and agrees as follows:

          (a)  Compliance With Laws. Such Underwriter will comply in all
               --------------------
     material respects with all legal requirements in connection with offers and
     sales of the Securities and make such offers and sales in the manner
     provided in the Prospectus.

          (b)  Offering Document. Such Underwriter will not use, or distribute
               -----------------
     to other broker-dealers for use, any Offering Document in connection with
     the offer and sale of the Securities unless such Offering Document includes
     such information as has been furnished by Financial Security for inclusion
     therein and the information therein concerning Financial Security has been
     approved by Financial Security in writing. Financial Security hereby
     consents to the information in respect of Financial Security included in
     the Prospectus. Each Offering Document will include the following
     statement:

          "The Policy is not covered by the property/casualty
          insurance security fund specified in Article 76 of the New
          York Insurance Law".

     Each Offering Document including financial information with respect to
     Financial Security prepared in accordance with generally accepted
     accounting principles (but excluding any Offering Document in which such
     financial statements are incorporated by reference) will include the
     following statement immediately preceding such financial information:

          "The New York State Insurance Department recognizes only
          statutory accounting practices for determining and reporting
          the financial condition and results of operations of an
          insurance company, for determining its solvency under the
          New York Insurance Law, and for determining whether its
          financial condition

                                       5
<PAGE>

          warrants the payment of a dividend to its stockholders. No
          consideration is given by the New York State Insurance
          Department to financial statements prepared in accordance
          with generally accepted accounting principles in making such
          determinations."

          (c)  Underwriter Information. All material provided by the
               -----------------------
     Underwriters for inclusion in the Prospectus (as revised from time to time,
     the "Underwriter Information"), insofar as such information relates to the
          -----------------------
     Underwriters, is true and correct in all material respects. In respect of
     the Prospectus Supplement, the Underwriter Information is limited to the
     information set forth (i) on the cover page of the Prospectus Supplement in
     the table containing the price to the public, the underwriting discount and
     the proceeds to the Seller with respect to the Securities and (ii) in the
     paragraphs immediately following the tables under the caption
     "Underwriting".

     Section 4. Indemnification.
                ---------------

          (a)  Financial Security agrees, upon the terms and subject to the
     conditions provided herein, to indemnify, defend and hold harmless each
     Seller Party and each Underwriter Party against (i) any and all Losses
     incurred by them with respect to the offer and sale of the Securities and
     resulting from Financial Security's breach of any of its representations,
     warranties or agreements set forth in Section 2 hereof and (ii) any and all
     Losses to which any Seller Party or Underwriter Party may become subject,
     under the Securities Act or otherwise, insofar as such Losses arise out of
     or result from an untrue statement of a material fact contained in any
     Offering Document or the omission to state therein a material fact required
     to be stated therein or necessary to make the statements therein not
     misleading, in each case to the extent, but only to the extent, that such
     untrue statement or omission was made in the Financial Security Information
     included therein in accordance with the provisions hereof.

          (b)  Each of the Underwriters, agrees, upon the terms and subject to
     the conditions provided herein, to indemnify, defend and hold harmless each
     Financial Security Party and each Seller Party against (i) any and all
     Losses incurred by them with respect to the offer and sale of the
     Securities and resulting from the Underwriters' breach of any of its
     representations, warranties or agreements set forth in Section 3 hereof and
     (ii) any and all Losses to which any Financial Security Party or Seller
     Party may become subject, under the Securities Act or otherwise, insofar as
     such Losses arise out of or result from an untrue statement of a material
     fact contained in any Offering Document or the omission to state therein a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading, in each case to the extent, but only to
     the extent, that such untrue statement or omission was made in the
     Underwriter Information included therein.

          (c)  Upon the incurrence of any Losses for which a party is entitled
     to indemnification hereunder, the Indemnifying Party shall reimburse the
     Indemnified Party promptly upon establishment by the Indemnified Party to
     the Indemnifying Party of the Losses incurred.

                                       6
<PAGE>

     Section 5.  Indemnification Procedures. Except as provided below in Section
                 --------------------------
6 with respect to contribution, the indemnification provided herein by an
Indemnifying Party shall be the exclusive remedy of any and all Indemnified
Parties for the breach of a representation, warranty or agreement hereunder by
an Indemnifying Party; provided, however, that each Indemnified Party shall be
                       --------  -------
entitled to pursue any other remedy at law or in equity for any such breach so
long as the damages sought to be recovered shall not exceed the Losses incurred
thereby resulting from such breach. In the event that any action or regulatory
proceeding shall be commenced or claim asserted which may entitle an Indemnified
Party to be indemnified under this Agreement, such party shall give the
Indemnifying Party written or telegraphic notice of such action or claim
reasonably promptly after receipt of written notice thereof. The Indemnifying
Party shall be entitled to participate in and, upon notice to the Indemnified
Party, assume the defense of any such action or claim in reasonable cooperation
with, and with the reasonable cooperation of, the Indemnified Party. The
Indemnified Party will have the right to employ its own counsel in any such
action in addition to the counsel of the Indemnifying Party, but the fees and
expenses of such counsel will be at the expense of such Indemnified Party,
unless (a) the employment of counsel by the Indemnified Party at its expense has
been authorized in writing by the Indemnifying Party, (b) the Indemnifying Party
has not in fact employed counsel satisfactory to Financial Security to assume
the defense of such action within a reasonable time after receiving notice of
the commencement of the action, or (c) the named parties to any such action or
proceeding (including any impleaded parties) include both the Indemnifying Party
and one or more Indemnified Parties, and the Indemnified Parties shall have been
advised by counsel that (A) there may be one or more legal defenses available to
them which are different from or additional to those available to the
Indemnifying Party and (B) the representation of the Indemnifying Party and such
Indemnified Parties by the same counsel would be inappropriate or contrary to
prudent practice (in which case, if such Indemnified Parties notify the
Indemnifying Party in writing that they elect to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense of such action or proceeding on behalf of such
Indemnified Parties, it being understood, however, that the Indemnifying Party
shall not, in connection with any one such action or proceeding or separate but
substantially similar or related actions or proceedings in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys at any
time for all Seller Parties, one such firm for all Underwriter Parties and one
such firm for all Financial Security Parties, as the case may be, which firm
shall be designated in writing by the Seller in respect of the Seller Parties,
by the Underwriters in respect of the Underwriter Parties and by Financial
Security in respect of the Financial Security Parties), in each of which cases
the fees and expenses of counsel will be at the expense of the Indemnifying
Party and all such fees and expenses will be reimbursed promptly as they are
incurred. The Indemnifying Party shall not be liable for any settlement of any
such claim or action unless the Indemnifying Party shall have consented thereto
or be in default in its obligations hereunder. Any failure by an Indemnified
Party to comply with the provisions of this Section shall relieve the
Indemnifying Party of liability only if such failure is prejudicial to the
position of the Indemnifying Party and then only to the extent of such
prejudice.

     Section 6.  Contribution.
                 ------------

                                       7
<PAGE>

          (a)  To provide for just and equitable contribution if the
     indemnification provided by any Indemnifying Party is determined to be
     unavailable for any Indemnified Party (other than due to application of
     this Section), each Indemnifying Party shall contribute to the Losses
     arising from any breach of any of its representations, warranties or
     agreements contained in this Agreement on the basis of the relative fault
     of each of the parties as set forth in Section 6(b) below; provided,
                                                                --------
     however, that an Indemnifying Party shall in no event be required to
     -------
     contribute to all Indemnified Parties an aggregate amount in excess of the
     Losses incurred by such Indemnified Parties resulting from the breach of
     representations, warranties or agreements contained in this Agreement.

          (b)  The relative fault of each Indemnifying Party, on the one hand,
     and of each Indemnified Party, on the other, shall be determined by
     reference to, among other things, whether the breach of, or alleged breach
     of, any representations, warranties or agreements contained in this
     Agreement relates to information supplied by, or action within the control
     of, the Indemnifying Party or the Indemnified Party and the parties'
     relative intent, knowledge, access to information and opportunity to
     correct or prevent such breach.

          (c)  The parties agree that Financial Security shall be solely
     responsible for the Financial Security Information and the Underwriters
     shall be solely responsible for the Underwriter Information and that the
     balance of each Offering Document shall be the responsibility of the
     Seller.

          (d)  Notwithstanding anything in this Section 6 to the contrary, the
     Underwriters shall not be required to contribute an amount in excess of the
     amount by which the total price of the Securities underwritten by the
     Underwriters exceeds the amount of any damages that the Underwriters have
     otherwise been required to pay in respect of such untrue statement or
     omission.

          (e)  No person guilty of fraudulent misrepresentation (within the
     meaning of Section 11(f) of the Securities Act) shall be entitled to
     contribution from any person who was not guilty of such fraudulent
     misrepresentation.

          (f)  Upon the incurrence of any Losses entitled to contribution
     hereunder, the contributor shall reimburse the party entitled to
     contribution promptly upon establishment by the party entitled to
     contribution to the contributor of the Losses incurred.

                                   EXHIBIT A

                     OPINION OF ASSISTANT GENERAL COUNSEL

     Based upon the foregoing, I am of the opinion that:

     1.   Financial Security is a stock insurance company duly organized,
validly existing and authorized to transact financial guaranty insurance
business under the laws of the State of New York.

     2.   The Policy and the Financial Security Agreements have been duly
authorized, executed and delivered by Financial Security.

     3.   The Policy and the Financial Security Agreements constitute valid and
binding obligations of Financial Security, enforceable against Financial
Security in accordance with their terms, subject, as to the enforcement of
remedies, to bankruptcy, insolvency, reorganization, rehabilitation, moratorium
and other similar laws affecting the enforceability of creditors' rights
generally applicable in the event of the bankruptcy or insolvency of Financial
Security and to the application of general principles of equity and subject, in
the case of the Indemnification Agreement, to principles of public policy
limiting the right to enforce the indemnification provisions contained therein
insofar as they relate to indemnification for liabilities arising under
applicable securities laws.

     4.   The Policy is exempt from registration under the Securities Act of
1933, as amended (the "Act").
                       ---

     5.   Neither the execution or delivery by Financial Security of the Policy
or the Financial Security Agreements, nor the performance by Financial Security
of its obligations thereunder, will conflict with any provision of the
certificate of incorporation or the bylaws of Financial Security or violate any
law or regulation, which violation would impair the binding effect or
enforceability of the Policy or any of the Agreements or, to the best of my
knowledge, result in a breach of, or constitute a default under, any agreement
or other instrument to which Financial Security is a party or by which it or any
of its property is bound or, to the best of my knowledge, violate any judgment,
order or decree applicable to Financial Security of any governmental or
regulatory body, administrative agency, court or arbitrator having jurisdiction
over Financial Security (except that in the published opinion of the Securities
and Exchange Commission the indemnification provisions of the Indemnification
Agreement, insofar as they relate to indemnification for liabilities arising
under the Act, are against public policy as expressed in the Act and are
therefore unenforceable).

     In addition, please be advised that I have reviewed the description of
Financial Security under the caption "The Insurer" in the Prospectus (the
"Offering Document") of the Seller with respect to the Securities.  The
 -----------------
information provided in the Offering Document with respect to Financial Security
is limited and does not purport to provide the scope of disclosure required to
be included in a prospectus with respect to a registrant under the Act in
connection with the

                                      A-1
<PAGE>

public offer and sale of securities of such registrant. Within such limited
scope of disclosure, however, there has not come to my attention any information
which would cause me to believe that the description of Financial Security
referred to above, as of the date of the Offering Document or as of the date of
this opinion, contained or contains any untrue statement of a material fact or
omitted or omits to state a material fact necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading (except that I express no opinion with respect to any financial
statements or other financial information contained or referred to therein).
