  The Underwriters represent, warrant and covenant as of the Closing Date as

                  (a) Compliance With Laws. The Underwriters will comply in all
         material respects with all legal requirements in connection with offers
         and sales of the Notes and will make such offers and sales in the
         manner to be provided in the Offering Document.

                  (b) Offering Document. The Underwriters will not use, or
         distribute to other broker-dealers for use, any Offering Document in
         connection with the offer and sale of the Notes unless such Offering
         Document includes such information relating to the Insurer as has been
         furnished by the Insurer for inclusion therein and has been approved by
         the 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' Information"): the information contained under the
         heading "Underwriting" in the Offering Document.
   4
 .  The Insurer represents and warrants to the Underwriters as follows:

                  (a) Organization and Licensing. The 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 Insurer has the corporate power and
         authority to issue the Policy and execute this Indemnification
         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 Indemnification Agreement 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
         Indemnification Agreement will each constitute a legal, valid and
         binding obligation of the 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 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 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 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 Insurer
         that would materially and adversely affect its ability to perform its
         obligations under the Policy.
   5
                  (f) Insurer Information. The information in the Offering
         Document as of the date hereof under the caption "The Insurer and The
         Policy" (the "Insurer Information") is true and correct in all material
         respects and does not contain any untrue statement of a material fact.

                  (g) Rating. The 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 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 Insurer's knowledge,
         threatened against it at law or in equity or before or by any court,
         governmental agency, board or commission or any 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.



                  (a) The Underwriters hereby agree to pay, and to protect,
         indemnify and save harmless, the Insurer and its officers, directors,
         shareholders, employees, agents and each Person, if any, who controls
         the 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, warranties and covenants of the Underwriters contained
         in Section 3.

                  (b) The Insurer agrees to pay, and to protect, indemnify and
         save harmless, the Underwriters and their respective officers,
         directors, shareholders, employees, agents and each Person, if any, who
         controls either of the 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
   6
         in the Insurer Information or a breach of any of the representations
         and warranties of the 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 indemnification provided
         in this Section 5(a) or (b) may be sought from either of the
         Underwriters, on the one hand, or the 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 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
   7
         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 neither of the Underwriters
         shall be liable for any amount in excess of (i) the excess of the sales
         prices of the Notes 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, warranties or covenants set
         forth herein was 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.

                           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.

terminated only by written instrument or written instruments signed by the
parties hereto.
