      manner to be provided in the Offering Document.

            (b) Offering Document. Such Underwriter will not use, or distribute
      to other broker-dealers for use, any Offering Document in connection with

      furnished by the Certificate Insurer for inclusion therein and has been
      approved by the Certificate Insurer.

            (c) Underwriters' Information. All material provided by the
      Underwriters for inclusion in the Offering Document (as revised from time
      to time), shall be true and correct in all material respects, it being
      understood and agreed that the only such information furnished by the
      Underwriters consists of the following information (collectively, the
      "Underwriters' Information"): the information regarding the Underwriters
      contained under the heading "Underwriting" in the Offering Document.

      Section 4. Representations and Warranties of the Certificate Insurer. The
Certificate Insurer represents and warrants to each Underwriter as follows:

            (a) Organization and Licensing. The Certificate Insurer is a duly
      organized and licensed and validly existing Wisconsin stock insurance
      company duly qualified to conduct an insurance business in the State of
      New York.

            (b) Corporate Power. The Certificate Insurer has the corporate power
      and authority to issue the Policy and execute this Indemnity Agreement and
      to perform all of its obligations hereunder and thereunder.

            (c) Authorization; Approvals. Proceedings legally required for the
      issuance of the Policy and the execution, delivery and performance of this
      Indemnity Agreement
   7
      have been taken and all material licenses, orders, consents or other
      authorizations or approvals of any governmental boards or bodies legally
      required for the enforceability of the Policy have been obtained; any
      proceedings not taken and any licenses, authorizations or approvals not
      obtained are not material to the enforceability of the Policy.

            (d) Enforceability. The Policy, when issued, and this Indemnity
      Agreement will each constitute a legal, valid and binding obligation of
      the Certificate Insurer, enforceable in accordance with its terms, subject
      to insolvency, reorganization, moratorium, receivership and other similar
      laws affecting creditors' rights generally and by general principles of
      equity and subject to principles of public policy limiting the right to
      enforce the indemnification provisions contained therein and herein,
      insofar as such provisions relate to indemnification for liabilities
      arising under federal securities laws.

            (e) Financial Information. The consolidated financial statements of
      the Certificate Insurer and subsidiaries as of December 31, 1998 and
      December 31, 1997, and for each of the years in the three-year period
      ended December 31, 1998, prepared in accordance with generally accepted
      accounting principles, included in the Annual Report on Form 10-K of Ambac
      Financial Group, Inc. (which was filed with the Commission on March 30,
      1999; Commission File Number 1-10777) and the unaudited consolidated
      financial statements of the Certificate Insurer and subsidiaries as of
      June 30, 1999 and for the periods ending June 30, 1999 and June 30, 1998
      included in the Quarterly Report on Form 10-Q of Ambac Financial Group,
      Inc. for the period ended June 30, 1999 (which was filed with the
      Commission on August 13, 1999), which are incorporated by reference in the
      Offering Document, fairly present in all material respects the financial
      condition of the Certificate Insurer as of such dates and for the periods
      covered by such statements in accordance with generally accepted
      accounting principles consistently applied. Since June 30, 1999, there has
      been no material change in such financial condition of the Certificate
      Insurer that would materially and adversely affect its ability to perform
      its obligations under the Policy.

            (f) Certificate Insurer Information. The information in the Offering
      Document as of the date hereof under the captions "The Certificate
      Insurer" and "The Certificate Insurance Policy" (together, the
      "Certificate Insurer Information") is true and correct in all material
      respects and does not contain any untrue statement of a material fact.

            (g) Rating. The Certificate Insurer is not aware of any facts that
      if disclosed to Moody's or S&P would be reasonably expected to result in a
      downgrade of the rating of the financial strength of the Certificate
      Insurer by either of such Rating Agencies.

            (h) No Litigation. There are no actions, suits, proceedings or
      investigations pending or, to the best of the Certificate Insurer's
      knowledge, threatened against it at law or in equity or before or by any
      court, governmental agency, board or commission or any
   8
      arbitrator which, if decided adversely, would result in a Material Adverse
      Change or would materially and adversely affect its ability to perform its
      obligations under the Policy or this Indemnification Agreement.

            (i) 1933 Act Registration. The Policy is exempt from registration
      under the Securities Act.

      Section 5. Indemnification.

            (a) The Underwriters hereby severally agree to pay, and to protect,
      indemnify and save harmless, the Certificate Insurer and its officers,
      directors, shareholders, employees, agents and each Person, if any, who
      controls the Certificate Insurer within the meaning of either Section 15
      of the Securities Act or Section 20 of the Securities Exchange Act from
      and against, any and all claims, losses, liabilities (including
      penalties), actions, suits, judgments, demands, damages, costs or expenses
      (including reasonable fees and expenses of attorneys, consultants and
      auditors and reasonable costs of investigations) of any nature arising out
      of or by reason of any untrue statement of a material fact or an omission
      to state a material fact necessary in order to make the statements therein
      in light of the circumstances in which they were made not misleading,
      contained in the Underwriters' Information or a breach of any of the
      representations and warranties of the Underwriters contained in Section 3.

            (b) The Certificate Insurer agrees to pay, and to protect, indemnify
      and save harmless, each Underwriters and their respective officers,
      directors, shareholders, employees, agents and each Person, if any, who
      controls such Underwriters within the meaning of either Section 15 of the
      Securities Act or Section 20 of the Securities Exchange Act from and
      against, any and all claims, losses, liabilities (including penalties),
      actions, suits, judgments, demands, damages, costs or expenses (including
      reasonable fees and expenses of attorneys, consultants and auditors and
      reasonable costs of investigations) of any nature arising out of or by
      reason of any untrue statement of a material fact or an omission to state
      a material fact necessary in order to make the statements therein in light
      of the circumstances in which they were made not misleading, contained in
      the Certificate Insurer Information or a breach of any of the
      representations and warranties of the Certificate Insurer contained in
      Section 4.

            (c) If any action or proceeding (including any governmental
      investigation) shall be brought or asserted against any Person
      (individually, an "Indemnified Party" and, collectively, the "Indemnified
      Parties") in respect of which the indemnity provided in this Section 5(a)
      or (b) may be sought from any of the Underwriters, on the one hand, or the
      Certificate Insurer, on the other (each, an "Indemnifying Party")
      hereunder, each such Indemnified Party shall promptly notify the
      Indemnifying Party in writing, and the Indemnifying Party shall assume the
      defense thereof, including the employment of counsel reasonably
      satisfactory to the Indemnified Party and the payment of all expenses. The
      Indemnified Party shall have the right to employ separate counsel in any
      such action


   9
      and to participate in the defense thereof at the expense of the
      Indemnified Party; provided, however, that the fees and expenses of such
      separate counsel shall be at the expense of the Indemnifying Party if (i)
      the Indemnifying Party has agreed to pay such fees and expenses, (ii) the
      Indemnifying Party shall have failed to assume the defense of such action
      or proceeding and employ counsel reasonably satisfactory to the
      Indemnified Party in any such action or proceeding or (iii) the named
      parties to any such action or proceeding (including any impleaded parties)
      include both the Indemnified Party and the Indemnifying Party, and the
      Indemnified Party shall have been advised by counsel that there may be one
      or more legal defenses available to it which are different from or
      additional to those available to the Indemnifying Party (in which case, if
      the Indemnified Party notifies the Indemnifying Party in writing that it
      elects 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 Party,
      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 the Indemnified Parties, which firm
      shall be designated in writing by the Indemnified Party). The Indemnifying
      Party shall not be liable for any settlement of any such action or
      proceeding effected without its written consent to the extent that any
      such settlement shall be prejudicial to the Indemnifying Party, but, if
      settled with its written consent, or if there is a final judgment for the
      plaintiff in any such action or proceeding with respect to which the
      Indemnifying Party shall have received notice in accordance with this
      subsection (c), the Indemnifying Party agrees to indemnify and hold the
      Indemnified Parties harmless from and against any loss or liability by
      reason of such settlement or judgment.

            (d) To provide for just and equitable contribution if the
      indemnification provided by the Indemnifying Party is determined to be
      unavailable or insufficient to hold harmless any Indemnified Party (other
      than due to application of this Section), each Indemnifying Party shall
      contribute to the losses incurred by the Indemnified Party on the basis of
      the relative fault of the Indemnifying Party, on the one hand, and the
      Indemnified Party, on the other hand provided, that no Underwriter shall
      be liable for any amount in excess of (i) the excess of the sales prices
      of the Certificates to the public over the prices paid therefor by the
      Underwriters over (ii) the aggregate amount of any damages which the
      Underwriters have otherwise been required to pay in respect of the same or
      any substantially similar claim.

                  The relative fault of each Indemnifying Party, on the one
      hand, and each Indemnified Party, on the other, shall be determined by
      reference to, among other things, whether the breach of, or alleged breach
      of, any of its representations and warranties set forth 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
   10
      prevent such breach.

                  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.

      Section 6. Amendments, Etc. This Indemnity Agreement may be amended,
modified, supplemented or terminated only by written instrument or written
instruments signed by the parties hereto.
