         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 Underwriter will not use, or
         distribute to other broker-dealers for use, any Offering Document in

         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) Underwriter Information. All material provided by the
         Underwriter for inclusion in the Offering Document (as revised from
         time to time), is true and correct in all material respects, it being
         understood and agreed that the only such information furnished by the
         Underwriter consists of the following information (collectively, the
         "Underwriter Information"): the information contained in the fifth
         paragraph under the caption "Underwriting" in the Offering Document.

         Section 4. Representations and Warranties of the Insurer. The Insurer
represents and warrants to the Underwriter 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 or are not material to the
         enforceability of the Policy.

                                       2

                  (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
         September 30, 1999 and for the periods ending September 30, 1999 and
         September 30, 1998 included in the Quarterly Report on Form 10-Q of
         Ambac Financial Group, Inc. for the period ended September 30, 1999
         (which was filed with the Commission on November 12, 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
         September 30, 1999, there has been no change in the financial condition
         of the Insurer that would materially and adversely affect its ability
         to perform its obligations under the Policy.

                  (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 rating 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, this Indemnification Agreement or the Insurance and
         Indemnity Agreement.

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

         Section 5. Indemnification.

                  (a) The Underwriter hereby agrees to pay, and to protect,
         indemnify and hold 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 Underwriter Information or a breach of any of the
         representations and warranties of the Underwriter contained in Section
         3.

                  (b) The Insurer agrees to pay, and to protect, indemnify and
         hold harmless, the Underwriter and its respective officers, directors,
         shareholders, employees, agents and each Person, if any, who controls
         such Underwriter 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 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 indemnity provided in
         this Section 5(a) or (b) may be sought from the Underwriter, 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 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

                                       4
<PAGE>

         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
         the Underwriter shall not be liable for any amount in excess of (i) the
         excess of the sales prices of the Offered Notes to the public over the
         prices paid therefor by the Underwriter over (ii) the aggregate amount
         of any damages which the Underwriter has 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 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.

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

         Section 7. Notices. All demands, notices and other communications to be
given hereunder shall be in writing (except as otherwise specifically provided
herein) and shall be mailed by registered mail or personally delivered and
