4. Restrictions on Transfer of Stockholder Shares.

(a) Transfer of Stockholder Shares.

(i) No holder of Stockholder Shares shall sell, transfer, assign, pledge or otherwise dispose of (whether with or without consideration and whether voluntarily or involuntarily or by operation of law, including by way of merger or consolidation) any interest in its Stockholder Shares (a “Transfer”), except pursuant to the provisions of this Section 4 or Section 5 or pursuant to a Public Offering. No Stockholder shall consummate any Transfer (other than pursuant to a Sale of the Company or a Public Offering) until 30 days after the later of the delivery to the Company and the Offerees (as defined below) of such Stockholder’s Offer Notice or Sale Notice (if any), unless the parties to the Transfer have been finally determined pursuant to this Section 4 prior to the expiration of such 30-day period (the “Election Period”).

(ii) Without limiting the generality of Section 4(a)(i), no Employee shall Transfer any Stockholder Shares held by such Employee on the date hereof or hereafter acquired, except pursuant to a Sale of the Company or a Public Offering; provided that nothing contained in this Section 4(a)(ii) shall prohibit any Employee from transferring Stockholder Shares as permitted by Section 4(c) or 4(d).

(b) First Refusal Right. At least 30 days prior to making any Transfer of any Stockholder Shares (other than pursuant to a Sale of the Company or a Public Offering), the transferring Stockholder (the “Transferring Stockholder”) shall deliver a written notice (an “Offer Notice”) to the Company and to the holders of the Series B Preferred Stock (the “Offerees”). The Offer Notice shall disclose in reasonable detail the proposed type, class or series, and number of Stockholder Shares to be transferred, the proposed terms and conditions of the Transfer and the identity, background and ownership (if applicable) of the prospective transferee(s), and the Offer Notice shall constitute an irrevocable binding offer to sell the Stockholder Shares to the Offerees on such terms and conditions. Each Offeree may elect to purchase all or any portion of the Stockholder Shares specified in the Offer Notice at the price and on the terms specified therein by delivering written notice of such election to the Transferring Stockholder as soon as practical, but in any event within 20 days after delivery of the Offer Notice. If more than one Offeree has elected to purchase the Stockholder Shares specified in the Offer Notice, the number of Stockholder Shares subject to each such agreement shall be proportionate to such Offerees’ relative Pro Rata Share (but in no event will an Offeree be obligated to purchase more than the number of Stockholder Shares specified in its election notice), or on such other basis as such Offerees shall agree. If any one or more Offerees have elected to purchase any Stockholder Shares specified in the Offer Notice, the sale of such Stockholder Shares shall be consummated as soon as practical after the delivery of the election notice(s) to the Transferring Stockholder, but in any event within 45 days after the expiration of the Election Period, subject to any required regulatory approvals. To the extent that the Offerees have not elected to purchase all of the Stockholder Shares being offered, the Transferring Stockholder may, within 90 days after the expiration of the Election Period and subject to the provisions of Section 4(c) below, transfer such Stockholder Shares to the Person or group of Persons identified in the Offer Notice, at a price no less than the price per share specified in the Offer Notice and on other terms no more favorable to the transferees thereof than offered to the Offerees in the Offer Notice. Any Stockholder Shares not transferred within such 90-day period shall be reoffered to the Offerees under this Section 4(b) prior to any subsequent Transfer. The purchase price specified in any Offer Notice shall be payable solely in cash at the closing of the transaction or in installments over time, and no Stockholder Shares may be subject to a pledge. Each Stockholder’s “Pro Rata Share” shall be based upon such Stockholder’s proportionate ownership of all shares of Series B Preferred Stock owned by Stockholders other than the Transferring Stockholder.

(i) At least 30 days prior to any Transfer (other than pursuant to a Public Offering or a Transfer to the Offerees pursuant to Section 4(b)) of Stockholder Shares constituting more than 50 percent of the then outstanding Common Stock Equivalents, the Stockholder or group of Stockholders making such Transfer (the

“Section 4(c) Transferring Stockholder”) shall deliver a written notice (the “Sale Notice”) to the Company and the other Stockholders (the “Participating Stockholders”), specifying in reasonable detail the identity, background and ownership (if applicable) of the prospective transferee(s), the type, class or series, and number of shares to be transferred and the terms and conditions of the Transfer (which notice may be the same notice and given at the same time as the Offer Notice under Section 4(b)).

(ii) The Participating Stockholders may elect to participate in the contemplated Transfer at the same price per Common Stock Equivalent and on the same terms by delivering written notice to the Section 4(c) Transferring Stockholder within 20 days after delivery of the Sale Notice. If any Participating Stockholder has elected to participate in such Transfer, each of the Section 4(c) Transferring Stockholder and the Participating Stockholders will be entitled to include in the contemplated Transfer, subject to Section 4(c)(iii), the number of Common Stock Equivalents equal to the product of (i) the quotient determined by dividing (x) the number of Common Stock Equivalents held by such Person by (y) the aggregate number of Common Stock Equivalents held by such Section 4(c) Transferring Stockholder and the Participating Stockholders and (ii) the aggregate number of Common Stock Equivalents to be Transferred in the contemplated Transfer. Any of the Participating Stockholders may elect to sell in any Transfer contemplated under this Section 4(c) a lesser number of Common Stock Equivalents than such Participating Stockholder is entitled to sell hereunder, in which case the Section 4(c) Transferring Stockholder shall have the right to sell an additional number of Common Stock Equivalents in such Transfer equal to the number that such Participating Stockholder has elected not to sell.

(iii) If the Section 4(c) Transferring Stockholder contemplates Transferring Stockholder Shares (other than shares of Common Stock) for a price per share that is less than the conversion price then in effect for such Stockholder Shares, then no Participating Stockholder shall be entitled to include in the proposed Transfer any Stockholder Shares that are junior in right of payment to such Stockholder Shares.

(iv) Each Section 4(c) Transferring Stockholder shall use reasonable efforts to obtain the agreement of the prospective transferee(s) to the participation of the Participating Stockholders in any contemplated Transfer, and no Section 4(c) Transferring Stockholder shall transfer any of its Stockholder Shares to any prospective transferee if such prospective transferee(s) declines to allow the participation of the Participating Stockholders. Each Participating Stockholder shall pay its pro rata share (based upon the consideration received upon such Transfer) of the expenses incurred by the Stockholders in connection with such transfer and shall be obligated to join on a pro rata basis (based upon the consideration received upon such Transfer)

in any indemnification or other obligations that the Section 4(c) Transferring Stockholder agrees to provide in connection with such transfer (other than any such obligations that relate specifically to a particular Stockholder such as indemnification with respect to representations and warranties given by a Stockholder regarding such Stockholder’s title to and ownership of Stockholder Shares; provided that no holder shall be obligated in connection with such Transfer to agree to indemnify or hold harmless the transferees with respect to an amount in excess of the net cash proceeds paid to such holder in connection with such Transfer)

(d) Permitted Transfers. The restrictions set forth in this Section 4 shall not apply with respect to any Transfer of Stockholder Shares by any Stockholder (i) in the case of an Employee or an Other Holder that is a natural person, by will or pursuant to applicable laws of descent and distribution or among such Employee’s or Other Holder’s, as applicable, Family Group, (ii), in the case of BSMB or an Other Holder that is not a natural person, among its Affiliates, or (iii) in the case of Insurance Partners, L.P., Insurance Partners Offshore (Bermuda), L.P. and IP/MCLP, L.L.C.

Notwithstanding the foregoing, no party hereto shall avoid the provisions of this Agreement by making one or more transfers to one or more Permitted Transferees and then disposing of all or any portion of such party’s interest in any such Permitted Transferee.

(e) This Section 4 shall terminate and cease to be effective upon the earlier to occur of the consummation of (i) a Sale of the Company pursuant to Section 5 or (ii) a Qualified Public Offering.

(a) If the holders of a majority in voting power of the Series B Preferred Stock then outstanding approve a Sale of the Company and deliver written notice to the holders of Stockholders Shares invoking the provisions of this Section 5 (any such sale, an “Approved Sale”), the holders of Stockholders Shares shall consent to, vote in favor of and raise no objections against the Approved Sale; provided, however, that if the definitive sale agreement governing an Approved Sale is entered into prior to the 18-month anniversary of the date hereof, then, unless a majority of the Board approves such Approved Sale (prior to the removal of any director pursuant to the second proviso of Section 1(a)(vi)) or unless Standard & Poor’s Rating Group, a division of XxXxxx-Xxxx Companies (“S&P”), shall have downgraded the A financial strength, corporate credit or financial enhancement rating of ACA Financial Guaranty Corporation (or shall have ceased rating ACA Financial Guaranty Corporation), the aggregate price per Common Stock Equivalent received in such an Approved Sale shall be not less than the Company’s Book Value Per Share as at the end of the most recently completed fiscal quarter for which the Company’s financial statements have been completed at the time such sale or similar agreement is executed.

(b) If the Approved Sale is structured as (i) a merger or consolidation, each holder of Stockholder Shares shall vote or cause to be voted such holder’s Stockholder Shares to approve such merger or consolidation, whether by written consent or at a stockholders meeting (as requested by the holders of a majority in voting power of the outstanding Series B Preferred Stock) and waive all dissenter’s rights, appraisal rights and similar rights in connection with such merger or consolidation, (ii) a sale of stock, then each holder of Stockholder Shares shall agree to sell, and shall sell, all of such holder’s Stockholder Shares and rights to acquire Stockholder Shares on the terms and conditions so approved by the holders of a majority in voting power of the outstanding Series B Preferred Stock or (iii) a sale of assets, each holder of Stockholder Shares shall vote or cause to be voted its Stockholder Shares to approve such sale and any subsequent liquidation of the Company or other distribution of the proceeds therefrom, whether by written consent or at a stockholders meeting (as requested by the holders of a majority in, voting power of the outstanding Series B Preferred Stock).

(c) In furtherance of the foregoing, (i) each holder of Stockholder Shares shall take, with respect to such holder’s Stockholder Shares, all necessary or desirable actions reasonably requested by the holders of a majority in voting power of the outstanding Series B Preferred Stock in connection with the consummation of the Approved Sale and (ii) each holder of Stockholder Shares shall make the same representations, warranties, indemnities and agreements as each other holder, including, without limitation, voting to approve such transaction and executing the applicable purchase agreement and related documents, except that (A) each holder of Stockholder Shares shall be obligated only to (1) make representations and warranties with respect to such holder’s title to and ownership of the Stockholder Shares actually Transferred in such Approved Sale, authorization, execution and delivery of relevant documents by such Stockholder, enforceability of relevant agreements against such holder and other matters relating to such holder, (2) enter into covenants in respect of a Transfer of such holder’s Stockholder Shares in connection with such Approved Sale and (3) enter into indemnification obligations with respect to the foregoing, in each case, to the extent that each other holder is similarly obligated, but no Stockholder shall be obligated to enter into indemnification obligations with respect to any of the foregoing with respect to such other holder or such other holder’s Stockholder Shares, and (B) in no event shall any Stockholder be liable in respect of any indemnity obligations with respect to such holder and the Company and its Subsidiaries in general pursuant to any Approved Sale in an aggregate amount in excess of the total consideration payable to such holder in such Approved Sale.

(d) The obligations of the holders of Stockholder Shares with respect to an Approved Sale are subject to the satisfaction of the following conditions: (i) upon the consummation of the Approved Sale, each holder of Stockholder Shares, to the extent it is receiving any consideration, will receive the same form of consideration as each other holder of Stockholder Shares, and the aggregate consideration will be distributed, as between the different classes or series of Stockholder Shares, based on the rights and preferences set forth in the Company’s Certificate of Incorporation as in effect immediately prior to such Approved Sale, and as between holders of Stockholder Shares of a particular class or series, ratably based on the Stockholder Shares of such class or series actually Transferred in the Approved Sale; (ii) if any holders of a series or class of Stockholder Shares are given an option as to the form and amount of consideration to be received, each holder of such series or class of Stockholder Shares will be

given the same option; and (iii) each holder of then currently exercisable rights to acquire shares of a class of Stockholder Shares will be given an opportunity to exercise such rights prior to the consummation of the Approved Sale and participate in such sale as holders of such class of Stockholder Shares. Each Stockholder acknowledges that, depending upon the aggregate consideration to be distributed in connection with the Approved Sale, certain classes or series of Stockholder Shares may receive less consideration per Common Stock Equivalent than other classes or series of Stockholder Shares, and certain classes or series may receive no consideration in the Approved Sale.

(e) If the Company or the holders of the Company’s securities enter into any negotiation or transaction for which Rule 506 (or any similar rule then in effect) promulgated by the United States Securities and Exchange Commission may be available with respect to such negotiation or transaction (including a merger, consolidation or other reorganization), the holders of Stockholder Shares shall, at the request of the Company, appoint a “purchaser representative” (as such term is defined in Rule 501) reasonably acceptable to the Company.

(g) This Section 5 shall terminate and cease to be effective upon the earlier to occur of the consummation of (i) a Sale of the Company pursuant to this Section 5 or (ii) a Qualified Public Offering.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS

AND CONDITIONS ON TRANSFER, AS SET FORTH IN A STOCKHOLDERS AGREEMENT, DATED AS OF SEPTEMBER 30, 2004, BY AND AMONG THE ISSUER OF SUCH SECURITIES (THE “COMPANY”) AND CERTAIN OF THE COMPANY’S STOCKHOLDERS, AS MAY BE AMENDED, AND MODIFIED FROM TIME TO TIME.

(b) The Board may elect to purchase all or any portion of the Repurchase Shares by delivering written notice (the “Repurchase Notice”) to the holder or holders of the Repurchase Shares within 90 days after the date of Termination. The Repurchase Notice shall set forth the number of Repurchase Shares to be acquired from each holder of Repurchase Shares, the aggregate consideration to be paid for such number of Repurchase Shares and the time and place for the closing of the transaction. The number of Repurchase Shares to be repurchased by the Company shall first be satisfied to the extent possible from the Repurchase Shares held by the Employee at the time of delivery of the Repurchase Notice. If the number of Repurchase Shares then held by the Employee is less than the total number of Repurchase Shares the Company has elected to purchase, the Company shall purchase the remaining Repurchase Shares elected to be purchased from the other holder(s) of Repurchase Shares, pro rata according to the number of Repurchase Shares held by such other holder(s) at the time of delivery of such Repurchase Notice (determined as close as practicable to the nearest whole share).

(c) Except as set forth in Section 8(e), the purchase price for the Repurchase Shares shall be their Fair Market Value as of the end of the fiscal quarter immediately preceding

the date of Termination. The “Fair Market Value” of any Repurchase Share shall be equal to the amount which the holder thereof would receive if the Company were to (i) sell for cash all its assets at fair market value on the date of determination (as determined by the Board in good faith), (ii) satisfy all its liabilities and (iii) then liquidate.

Any notes issued by the Company pursuant to this Section 8(d) shall be subject to any restrictive covenants to which the Company is subject at the time of such purchase.

This AMENDMENT NO. 1, dated as of November 23, 2004 (this “Amendment No. 1”), to the STOCKHOLDERS AGREEMENT, dated as of September 30, 2004 (the “Stockholders Agreement”), is among ACA Capital Holdings, Inc., a Delaware corporation (the “Company”), and the stockholders of the Company listed on the signature pages hereto.

WHEREAS, pursuant to Section 12 of the Stockholders Agreement, the Stockholders Agreement may be amended if the amendment is approved in writing by the Company, the holders of at least a majority of the Stockholder Shares (voting together as a single class, on an as-converted basis) and the holders of a majority of the Series B Preferred Stock;

WHEREAS, the Company and the parties hereto wish to amend the Stockholders Agreement to provide that other stockholders of the Company may become parties to the Stockholders Agreement by executing a Joinder Agreement in the form attached as Exhibit B hereto;

NOW, THEREFORE, in consideration of the agreements and obligations set forth herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

“Section 24. Joinder Agreements. Any holder of capital stock of the Company may become a party to this Agreement by executing a Joinder Agreement in the form attached hereto as Exhibit B and delivering such Joinder Agreement to the Company, and by executing a Consent of Spouse, if applicable, in the form attached to this Agreement as Exhibit A and delivering such Consent of Spouse to the Company. Upon such execution and delivery such holder shall be considered a Stockholder for all purposes of this Agreement and, upon such execution and delivery, the Company shall amend the Schedule of Stockholders to reflect such holder becoming a party to this Agreement and distribute a copy of such amended Schedule to all other parties for this Agreement.”

(b) The Stockholders Agreement is hereby amended to add a new Exhibit B in the form attached hereto.

“(iv) the composition of any committee of the Board or any Sub Board shall not exceed five members and shall include at least one BSMB Director;”

(d) The last sentence of Section 8(c) of the Stockholders Agreement is hereby amended and restated in its entirety to read as follows:

“The Fair Market Value” of any Repurchase Share shall be equal to the amount which the holder thereof would receive if the Company were to (i) sell for cash all of its assets at fair market value on the date of determination (as determined by the Board in good faith; provided, however, that if the Repurchase Shares are shares of Series C Senior Convertible Preferred Stock, or shares of Series B Senior Convertible Preferred Stock or Common Stock into which such Series C Senior Convertible Preferred Stock have been converted (“Series C Related Repurchase Shares”), then any Employee, or group of Employees together, holding a minimum of $100,000 of such shares (calculated attributing a value of $62.29 per share) shall have the right to request that a valuation of the Company’s assets by an independent appraiser approved by the Board be conducted in which case the fair market value of the assets shall be the higher of the value determined by the Board and the value established therefore by the independent appraiser; provided, further, however, that (x) the Company shall not be required to obtain an independent appraisal more than once in any 12 month period, and (y) any Employees holding Series C Related Repurchase Shares within the 12 month period following an independent valuation shall be entitled to rely on such valuation, provided that such valuation shall be subject to good faith adjustments to the fair market value of the assets based on changes in circumstances of the Company subsequent to the date of such valuation), (ii) satisfy all of its liabilities and (iii) liquidate.”

2. Governing Law.

This Amendment No. 1 shall be governed in all respects by the laws of the State of Delaware, without reference to the conflict of laws principles thereof.

3. Counterparts.

This Amendment No. 1 may be executed in any number of counterparts, and each such counterpart hereof shall be deemed to be an original instrument, but all such counterparts together shall constitute but one agreement.
