2.2 This Agreement and the put option created hereby shall remain in effect until the earlier to occur of the following:

(a) Ambac Assurance terminates this agreement by delivering a written notice to the Master Trust, on behalf of the Sub-Trust, stating that Ambac Assurance is terminating the Agreement on the next succeeding Auction Date that follows the notice by at least three (3) Business Days and indicating the Auction Date on which the termination shall become effective. Delivery of a termination notice by Ambac Assurance shall be irrevocable; and

(b) Ambac Assurance fails to make payment of the Put Option Premium or the Delayed Put Option Premium, if any, and such failure has not been cured within five (5) Business Days.

2.3 This Agreement shall terminate upon Ambac Assurance’s exercise of its rights under Section 3 and the payment of the Put Option Price under Section 4, provided, however, that Section 7.5 shall survive such termination.

Exercise of Put Option

3.1 The Master Trust, on behalf of the Sub-Trust, agrees that it shall, upon exercise of the option as provided in Section 3.2, purchase the Preferred Stock from Ambac Assurance for a purchase price equal to the Put Option Price, which Put Option Price shall be payable on the Put Option Payment Date in accordance with Section 4.

3.2 (a) Ambac Assurance may exercise the option at any time upon three (3) Business Days’ notice after the date hereof and prior to the termination of this Agreement by serving a Put Notice on the Master Trust, on behalf of the Sub-Trust, specifying a payment date (the “Put Option Payment Date”), which shall be the next Distribution Payment Date on or after the third Business Day after service of the Put Notice on the Master Trust, on behalf of the Sub-Trust. Any notice of exercise provided pursuant to this Section 3.2(a) shall be irrevocable.

(a) On the Put Option Payment Date, Ambac Assurance shall convey to the Master Trust, on behalf of the Sub-Trust, or its designee Preferred Stock with an aggregate liquidation preference equal to the aggregate face amount of the ABC Securities outstanding on the Put Option Payment Date. In addition, the number of shares of Preferred Stock delivered shall equal the number of ABC Securities outstanding on the Put Option Payment Date. The Preferred Stock shall be delivered free and clear of any defect in title, together with all transfer and registration documents (or all notices, instructions or other communications) as are necessary to convey title to the Preferred Stock to the Master Trust, on behalf of the Sub-Trust (or its nominee).

(b) For avoidance of doubt, (1) any cash received by the Master Trust, on behalf of the Sub-Trust, as interest or other payments earned on the principal amount of the Trust Property (net of fees and expenses and excluding any repayment of principal) and not distributed to Holders as of the Put Option Payment Date shall be distributed to Holders and shall not be used to purchase shares of Preferred Stock; and (2) the amount of Preferred Stock purchased from Ambac Assurance shall be reduced by the amount, if any, by which the aggregate face

amount of ABC Securities is reduced pursuant to principal or interest losses on Trust Property as a result of Defaults as required by the operation of Section 6.1(j) of the Declaration and Section 6(b) of the General Terms of the ABC Securities attached to the Declaration as Appendix A on or before the Put Option Payment Date.

Payments

4.1 Upon receipt of a Put Notice, the Master Trust will allow the then current assets of the Sub-Trust to mature, and will deliver the proceeds attributable to principal received upon maturity of the assets (after satisfying the Sub-Trust’s creditors, if any, and after any principal returned to holders of the ABC Securities pursuant to Section 6.1(j) of the Declaration and Section 6(b) of the General Terms of the ABC Securities attached to the Declaration as Appendix A) to Ambac Assurance on the Put Option Payment Date. The amount of such payment shall be referred to herein as the “Put Option Price.”

4.2 Payment by the Master Trust, on behalf of the Sub-Trust, of the Put Option Price shall be made on or prior to 3:00 p.m. on the Put Option Payment Date and to the account of Ambac Assurance specified in the Put Notice.

4.3 Payment of the Put Option Price by the Master Trust, on behalf of the Sub-Trust, shall be made as provided in Section 4.1 and Section 4.2 without setoff, claim, recoupment, deduction or counterclaim; provided, however, that if Ambac Assurance exercises its option under Section 3 hereof at any time that it has failed to pay all or a portion of the Put Option Premium or the Delayed Put Option Premium, if any, and such failure has not been cured on or before the Put Option Payment Date, the Master Trust, on behalf of the Sub-Trust, shall be entitled to set off against the Put Option Price such unpaid portion of the Put Option Premium or the Delayed Put Option Premium, as the case may be.

Put Option Premium

5.1 In consideration for the Master Trust’s agreement to purchase the Preferred Stock on behalf of the Sub-Trust in accordance with the terms of this Agreement, Ambac Assurance agrees to pay to the Master Trust, on behalf of the Sub-Trust, in US dollars, on each Distribution Payment Date, an amount equal to the product of (A) the Auction Rate on the ABC Securities for the respective Distribution Period less the Distribution Rate for such Distribution Period, (B) the aggregate face amount of the ABC Securities of the Sub-Trust outstanding at the time the Put Option Premium is calculated and (C) a fraction, the numerator of which will be the

number of calendar days in the respective Distribution Period, and the denominator of which will be 360 days.

The amount derived in accordance with such formula shall be known herein as the “Put Option Premium.”

If there is a Default during any Distribution Period, then Ambac Assurance agrees to pay to the Master Trust, on behalf of the Sub-Trust, in US dollars on each Distribution Payment Date following receipt of the Delayed Put Option Premium Certificate an amount, as determined by the Trustee, equal to the product of (A) the Delayed Auction Rate on the ABC Securities for the Delayed Auction Period less the Delayed Distribution Rate for such Distribution Period, (B) the aggregate face amount of the ABC Securities of the respective Sub-Trust outstanding at the time the Delayed Put Option Premium is calculated and (C) a fraction, the numerator of which will be the number of calendar days in the respective Delayed Auction Period, and the denominator of which will be 360 days.

The amount derived in accordance with such formula shall be known herein as the “Delayed Put Option Premium.”

5.2 The amount of the Put Option Premium shall be calculated by the Trustee and delivered in writing (the “Put Option Premium Certificate”), substantially in the form attached hereto as Annex B, to Ambac Assurance prior to 5:00 p.m. on each Auction Date. The amount of the Delayed Put Option Premium shall be calculated by the Trustee and delivered in writing (the “Delayed Put Option Premium Certificate”) to Ambac Assurance prior to 5:00 p.m. on the Delayed Auction Date. The Put Option Premium Certificate, and any Delayed Put Option Premium Certificate, also shall set forth the eligible assets held by the Sub-Trust, the anticipated yield earned on each such asset, any anticipated fees to be paid or incurred by the Trustee on behalf of the Trust and the computation of the Put Option Premium, or the Delayed Put Option Premium, as the case may be, in each case for the respective Distribution Period and the Delayed Auction Period, respectively, and shall be in the form attached hereto as Annex B.

5.3 If the Put Option Premium, or the Delayed Put Option Premium, if any, is not paid on the date on which it is due, interest shall accrue thereon at a rate equal to the maximum rate then in effect, during the five (5) day cure period set forth in Section 2.2(b) hereof until such Put Option Premium, or Delayed Put Option Premium, is paid.

Obligations Absolute

6.1 The Master Trust, on behalf of the Sub-Trust, acknowledges that, provided Ambac Assurance has complied with the terms of this Agreement, the obligations of the Master Trust, on behalf of the Sub-Trust, undertaken under this Agreement are absolute, irrevocable and unconditional irrespective of any circumstances whatsoever, including any defense otherwise available to the Master Trust, on behalf of the Sub-Trust, in equity or at law, including, without limitation, the defense of fraud, any defense based on the failure of Ambac Assurance to disclose any matter, whether or not material, to the Master Trust, on behalf of the Sub-Trust, or any other person, and any defense of breach of warranty or misrepresentation, and irrespective of any other circumstance which might otherwise constitute a legal or equitable discharge or defense of an insurer, surety or guarantor under any and all circumstances. The enforceability and effectiveness of this Agreement and the liability of the Master Trust, on behalf of the Sub-Trust, and the rights, remedies, powers and privileges of Ambac Assurance under this Agreement shall not be affected, limited, reduced, discharged or terminated, and the Master Trust, on behalf of the Sub-Trust, hereby expressly waives, to the fullest extent permitted by applicable law, any defense now or in the future arising by reason of:

(a) the illegality, invalidity or unenforceability of all or any part of the Declaration;

(b) any action taken by Ambac Assurance;

(c) any change in the direct or indirect ownership or control of Ambac Assurance or of any shares or ownership interests thereof;

(d) any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of or for the Master Trust, on behalf of the Sub-Trust;

provided, however, that notwithstanding the provisions of this Section 6.1, the Master Trust, on behalf of the Sub-Trust, shall have no further obligations under this Agreement after the termination of this Agreement. In addition, the breach of any covenant made in this Agreement by the Master Trust, on behalf of the Sub-Trust, shall not terminate this Agreement or limit the rights of Ambac Assurance hereunder.

6.2 For the avoidance of doubt, no failure or delay by Ambac Assurance in exercising its rights hereunder shall operate as a waiver of its rights hereunder (except as specifically provided in this Agreement, including, without limitation, in respect of the notice periods and payment dates set forth in Section 3.2(a)) and, subject to the termination of this Agreement not having occurred, Ambac Assurance may continue to exercise its rights hereunder at any time.

Covenants

7.1 Ambac Assurance hereby covenants and agrees that, at all times prior to the earlier of the termination of this Agreement or completion of the sale of the Preferred Stock to the Master Trust, on behalf of the Sub-Trust, pursuant to this Agreement, it shall not amend, restate, revise or otherwise alter the rights, terms and preferences of the Preferred Stock whether by operation of merger, reorganization or otherwise, without the prior consent of the Master Trust, on behalf of the Sub-Trust, and it will not register the Preferred Stock with the Securities and Exchange Commission under the Securities Act of 1933, as amended, on or before the Put Option Payment Date.

7.4 Ambac Assurance hereby covenants and agrees that if Ambac Assurance’s financial strength rating is ever lowered while this Agreement remains effective, Ambac Assurance shall provide written notice to the Trustee, on behalf of the Sub-Trust, of such lowered rating.

Such written assurance shall provide that the holders of the Preferred Stock shall be third party beneficiaries of, and entitled to enforce, the provisions of such assurance as if they were parties

Jurisdiction

16.1 Each of the parties hereto irrevocably submits to the non-exclusive jurisdiction of the courts of the State of New York in respect of any action or proceeding arising out of or in connection with this Agreement (“Proceedings”). Each of the parties hereto irrevocably waives, to the fullest extent permitted by applicable law, any objection that it may now or hereafter have to the laying of the venue of any such Proceedings in the courts of the State of New York and any claim that any Proceeding brought in any such court has been brought in an inconvenient forum. Each of the Master Trust, on behalf of the Sub-Trust, and Ambac Assurance agrees that it shall at all times have an authorized agent in the State of New York upon whom process may be served in connection with any Proceedings, and each of the Master Trust, on behalf of the Sub-Trust, and Ambac Assurance hereby authorizes and appoints the Trustee to accept service of all legal process arising out of or connected with this Agreement in the State of New York and service on such person (or substitute) shall be deemed to be service on the Master Trust, on behalf of the Sub-Trust, or Ambac Assurance, as the case may be. Except upon such a substitution, the Master Trust, on behalf of the Sub-Trust, and Ambac Assurance shall not revoke any such authority or appointment and shall at all times maintain an agent for service of process in the State of New York. If for any reason such person shall cease to act as agent for the service of process, the Master Trust, on behalf of the Sub-Trust, and Ambac Assurance shall promptly appoint another such agent, and shall forthwith notify each other of such appointment. The submission to jurisdiction reflected in this paragraph shall not (and shall not be construed so as to) limit the right of any person to take Proceedings in any court of competent jurisdiction, nor shall the taking of Proceedings in any one or more jurisdictions preclude the taking of Proceedings in any other jurisdiction (whether concurrently or not) if and to the extent permitted by law.

17.

Limitation of Liability

18.1 Ambac Assurance shall have the right to direct the Trustee to replace the Broker-Dealer at any time that Ambac Assurance believes, in the reasonable good faith exercise of its discretion, that the continued service of such Broker-Dealer could have an adverse impact on the rights and benefits conferred on Ambac Assurance pursuant to this Agreement.

18.2 In the event Ambac Assurance elects to exercise its right described in Section 18.1, Ambac Assurance shall propose to the Trustee a replacement Broker-Dealer. The Trustee shall enter into an agreement with such replacement Broker-Dealer, unless it has a reasonable basis for failing to do so, in which case the parties shall repeat such process until an acceptable Broker-Dealer is so selected.

IN WITNESS WHEREOF the parties hereto have caused this Put Option Agreement to be duly executed as of the day and year first above written.
