During each year while any of the Certificates are outstanding and unpaid, the governing body of the Issuer shall compute and ascertain a rate and amount of ad valorem tax that will be sufficient to raise and produce the money required to pay the interest on the Certificates as such interest comes due, and to provide and maintain a sinking fund adequate to pay the principal of the Certificates as such principal matures(but never less than 2% of the original amount of the Certificates as a sinking fund each year); and said tax shall be based on the latest approved tax rolls of the Issuer, with full allowances being made for tax delinquencies and the cost of tax collection. Said rate and amount of ad valorem tax is hereby levied, and is hereby ordered to be levied, against all taxable property in the Issuer, for each year while any of the Certificates are outstanding and unpaid, and said tax shall be assessed and collected each such year and deposited to the credit of the aforesaid Interest and Sinking Fund. Said ad valorem taxes sufficient to provide for 12 the payment of the interest on and principal of the Certificates, as such interest comes due and such principal matures, are hereby pledged for such payment, within the limit prescribed by law. Section 6. SURPLUS REVENUES. The Certificates are additionally secured by and payable from a pledge of the revenues of the Issuer's combined Waterworks and Sewer Systems remaining after payment of all operation and maintenance expenses thereof, and all debt service, reserve and other requirements in connection with all of the Issuer's revenue obligations (now or hereafter outstanding) that are payable from all or part of the Net Revenues of the Issuer's Waterworks and Sewer Systems, constituting "Surplus Revenues." The Issuer shall deposit such Surplus Revenues to the credit of the Interest and Sinking Fund created pursuant to Section 5, to the extent necessary to pay the principal and interest on the Certificates. Notwithstanding the requirements of Section 5, if Surplus Revenues are actually on deposit in the Interest and Sinking Fund in advance of the time when ad valorem taxes are scheduled to be levied for any year, then the amount of taxes that otherwise would have been required to be levied pursuant to Section 5 may be reduced to the extent and by the amount of the Surplus Revenues then on deposit in the Interest and Sinking Fund. Section 7. DEFEASANCE OF CERTIFICATES. (a) Any Certificate and the interest thereon shall be deemed to be paid, retired and no longer outstanding (a "Defeased Certificate") within the meaning of this Ordinance, except to the extent provided in subsection(d) of this Section 7, when payment of the principal of such Certificate, plus interest thereon to the due date (whether such due date be by reason of maturity or otherwise) either(i) shall have been made or caused to be made in accordance with the terms thereof, or(ii) shall have been provided for on or before such due date by irrevocably depositing with or making available to the Paying Agent/Registrar in accordance with an escrow agreement or other instrument (the "Future Escrow Agreement") for such payment (1)lawful money of the United States of America sufficient to make such payment or(2)Defeasance Securities that mature as to principal and interest in such amounts and at such times as will insure the availability,without reinvestment, of sufficient money to provide for such payment,and when proper arrangements have been made by the Issuer with the Paying Agent/Registrar for the payment of its services until all Defeased Certificates shall have become due and payable. At such time as a Certificate shall be deemed to be a Defeased Certificate hereunder, as aforesaid, such Certificate and the interest thereon shall no longer be secured by, payable from, or entitled to the benefits of, the ad valorem taxes or revenues herein levied and pledged as provided in this Ordinance, and such principal and interest shall be payable solely from such money or Defeasance Securities. Notwithstanding any other provision of this Ordinance to the contrary, it is hereby provided that any determination not to redeem Defeased Certificates that is made in conjunction with the payment arrangements specified in subsection 7(a)(i) or(ii) shall not be irrevocable, provided that: (1) in the proceedings providing for such payment arrangements, the Issuer expressly reserves the right to call the Defeased Certificates for redemption; (2) gives notice of the reservation of that right to the owners of the Defeased Certificates immediately following the making of the payment arrangements;and(3)directs that notice of the reservation be included in any redemption notices that it authorizes. (b) Any moneys so deposited with the Paying Agent/Registrar may at the written direction of the Issuer be invested in Defeasance Securities,maturing in the amounts and times as hereinbefore set forth,and all income from such Defeasance Securities received by the Paying Agent/Registrar that 13 is not required for the payment of the Certificates and interest thereon, with respect to which such money has been so deposited, shall be turned over to the Issuer, or deposited as directed in writing by the Issuer. Any Future Escrow Agreement pursuant to which the money and/or Defeasance Securities are held for the payment of Defeased Certificates may contain provisions permitting the investment or reinvestment of such moneys in Defeasance Securities or the substitution of other Defeasance Securities upon the satisfaction of the requirements specified in subsection 7(a)(i)or(ii). All income from such Defeasance Securities received by the Paying Agent/Registrar that is not required for the payment of the Defeased Certificates, with respect to which such money has been so deposited, shall be remitted to the Issuer or deposited as directed in writing by the Issuer. (c) The term "Defeasance Securities" means (i) direct, noncallable obligations of the United States of America, including obligations that are unconditionally guaranteed by the United States of America, (ii) noncallable obligations of an agency or instrumentality of the United States of America, including obligations that are unconditionally guaranteed or insured by the agency or instrumentality and that, on the date of the purchase thereof are rated as to investment quality by a nationally recognized investment rating firm not less than AAA or its equivalent, and(iii)noncallable obligations of a state or an agency or a county, municipality, or other political subdivision of a state that have been refunded and that, on the date the governing body of the Issuer adopts or approves the proceedings authorizing the financial arrangements are rated as to investment quality by a nationally recognized investment rating firm not less than AAA or its equivalent. (d) Until all Defeased Certificates shall have become due and payable, the Paying Agent/Registrar shall perform the services of Paying Agent/Registrar for such Defeased Certificates the same as if they had not been defeased, and the Issuer shall make proper arrangements to provide and pay for such services as required by this Ordinance. (e) In the event that the Issuer elects to defease less than all of the principal amount of Certificates of a maturity, the Paying Agent/Registrar shall select, or cause to be selected, such amount of Certificates by such random method as it deems fair and appropriate. Section 8. DAMAGED, MUTILATED, LOST, STOLEN, OR DESTROYED CERTIFICATES. (a) Replacement Certificates. In the event any outstanding Certificate is damaged, mutilated, lost, stolen or destroyed, the Paying Agent/Registrar shall cause to be printed, executed and delivered, a new certificate of the same principal amount, maturity and interest rate, as the damaged, mutilated, lost, stolen or destroyed Certificate, in replacement for such Certificate in the manner hereinafter provided. (b) Application for Replacement Certificates. Application for replacement of damaged, mutilated, lost, stolen or destroyed Certificates shall be made by the registered owner thereof to the Paying Agent/Registrar. In every case of loss, theft or destruction of a Certificate, the registered owner applying for a replacement certificate shall furnish to the Issuer and to the Paying Agent/Registrar such security or indemnity as may be required by them to save each of them harmless from any loss or damage with respect thereto. Also, in every case of loss, theft or destruction of a Certificate, the registered owner shall furnish to the Issuer and to the Paying Agent/Registrar 14 evidence to their satisfaction of the loss, theft or destruction of such Certificate, as the case may be. In every case of damage or mutilation of a Certificate, the registered owner shall surrender to the Paying Agent/Registrar for cancellation the Certificate so damaged or mutilated. (c) No Default Occurred. Notwithstanding the foregoing provisions of this Section, in the event any such Certificate shall have matured, and no default has occurred that is then continuing in the payment of the principal of, redemption premium, if any, or interest on the Certificate, the Issuer may authorize the payment of the same (without surrender thereof except in the case of a damaged or mutilated Certificate) instead of issuing a replacement Certificate, provided security or indemnity is furnished as above provided in this Section. (d) Charge for Issuing Replacement Certificates. Prior to the issuance of any replacement certificate, the Paying Agent/Registrar shall charge the registered owner of such Certificate with all legal, printing, and other expenses in connection therewith. Every replacement certificate issued pursuant to the provisions of this Section by virtue of the fact that any Certificate is lost, stolen or destroyed shall constitute a contractual obligation of the Issuer whether or not the lost, stolen or destroyed Certificate shall be found at any time, or be enforceable by anyone, and shall be entitled to all the benefits of this Ordinance equally and proportionately with any and all other Certificates duly issued under this Ordinance. (e) Authority for Issuing Replacement Certificates. In accordance with Subchapter D of Chapter 1201, Government Code, this Section 8 of this Ordinance shall constitute authority for the issuance of any such replacement certificate without necessity of further action by the governing body of the Issuer or any other body or person, and the duty of the replacement of such certificates is hereby authorized and imposed upon the Paying Agent/Registrar, and the Paying Agent/Registrar shall authenticate and deliver such Certificates in the form and manner and with the effect, as provided in Section 3(a) of this Ordinance for Certificates issued in conversion and exchange for other Certificates.

In addition, if bond insurance is obtained, the Certificates may bear an appropriate legend as provided by the insurer. 15 (b) The obligation of the initial purchaser to accept delivery of the Certificates is subject to the initial purchaser being furnished with the final, approving opinion of McCall, Parkhurst & Horton L.L.P., bond counsel to the Issuer, which opinion shall be dated as of and delivered on the date of initial delivery of the Certificates to the initial purchaser.

The Issuer covenants to take any action necessary to assure, or refrain from any action that would adversely affect,the treatment of the Certificates as Obligation described in section 103 of the Code, the interest on which is not includable in the "gross income" of the holder for purposes of federal income taxation. In furtherance thereof, the Issuer covenants as follows: (a) to take any action to assure that no more than 10 percent of the proceeds of the Certificates (less amounts deposited to a reserve fund, if any) are used for any "private business use," as defined in section 141(b)(6) of the Code or, if more than 10 percent of the proceeds or the projects financed therewith are so used, such amounts, whether or not received by the Issuer, with respect to such private business use, do not, under the terms of this Ordinance or any underlying arrangement,directly or indirectly, secure or provide for the payment of more than 10 percent of the debt service on the Certificates, in contravention of section 141(b)(2) of the Code; (b) to take any action to assure that in the event that the "private business use" described in subsection(a)hereof exceeds 5 percent of the proceeds of the Certificates or the projects financed therewith (less amounts deposited into a reserve fund, if any) then the amount in excess of 5 percent is used for a "private business use" that is "related" and not "disproportionate,"within the meaning of section 141(b)(3)of the Code,to the governmental use; (c) to take any action to assure that no amount that is greater than the lesser of $5,000,000, or 5 percent of the proceeds of the Certificates (less amounts deposited into a 16 reserve fund, if any)is directly or indirectly used to finance loans to persons, other than state or local governmental units, in contravention of section 141(c) of the Code; (d) to refrain from taking any action that would otherwise result in the Certificates being treated as "private activity bonds" within the meaning of section 141(b) of the Code; (e) to refrain from taking any action that would result in the Certificates being "federally guaranteed" within the meaning of section 149(b) of the Code; (f) to refrain from using any portion of the proceeds of the Certificates, directly or indirectly, to acquire or to replace funds that were used, directly or indirectly, to acquire investment property(as defined in section 148(b)(2)of the Code)that produces a materially higher yield over the term of the Certificates, other than investment property acquired with-- (1) proceeds ofthe Certificates invested for a reasonable temporary period of 3 years or less or, in the case of a refunding bond, for a period of 30 days or less until such proceeds are needed for the purpose for which the bonds are issued, (2) amounts invested in a bona fide debt service fund,within the meaning of section 1.148-1(b) of the Treasury Regulations, and (3) amounts deposited in any reasonably required reserve or replacement fund to the extent such amounts do not exceed 10 percent of the proceeds of the Certificates; (g) to otherwise restrict the use of the proceeds of the Certificates or amounts treated as proceeds of the Certificates, as may be necessary, so that the Certificates do not otherwise contravene the requirements of section 148 of the Code(relating to arbitrage)and, to the extent applicable, section 149(d) of the Code (relating to advance refundings); and (h) to pay to the United States of America at least once during each five-year period (beginning on the date of delivery of the Certificates) an amount that is at least equal to 90 percent of the"Excess Earnings,"within the meaning of section 148(f)of the Code and to pay to the United States of America, not later than 60 days after the Certificates have been paid in full, 100 percent of the amount then required to be paid as a result of Excess Earnings under section 148(f) of the Code. In order to facilitate compliance with the above covenant (h), a "Rebate Fund" is hereby established by the Issuer for the sole benefit of the United States of America, and such Fund shall not be subject to the claim of any other person, including without limitation the certificateholders. The Rebate Fund is established for the additional purpose of compliance with section 148 of the Code. For purposes of the foregoing (a) and (b), the Issuer understands that the term "proceeds" includes "disposition proceeds" as defined in the Treasury Regulations and, in the case of refunding 17 bonds, transferred proceeds (if any) and proceeds of the refunded bonds expended prior to the date of issuance of the Certificates. It is the understanding of the Issuer that the covenants contained herein are intended to assure compliance with the Code and any regulations or rulings promulgated by the U.S. Department of the Treasury pursuant thereto. In the event that regulations or rulings are hereafter promulgated that modify or expand provisions ofthe Code, as applicable to the Certificates, the Issuer will not be required to comply with any covenant contained herein to the extent that such failure to comply, in the opinion of nationally recognized bond counsel, will not adversely affect the exemption from federal income taxation of interest on the Certificates under section 103 of the Code. In the event that regulations or rulings are hereafter promulgated that impose additional requirements applicable to the Certificates, the Issuer agrees to comply with the additional requirements to the extent necessary, in the opinion of nationally recognized bond counsel, to preserve the exemption from federal income taxation of interest on the Certificates under section 103 of the Code.

For purposes of the foregoing, the portion of the property comprising personal property and disposed in the ordinary course shall not be treated as a transaction resulting in the receipt of cash or other compensation. For purposes hereof, the Issuer shall not be obligated to comply with this covenant if it obtains a legal opinion that such failure to comply will not adversely affect the excludability for federal income tax proposes from gross income of the interest. Section 14. INTEREST EARNINGS ON CERTIFICATE PROCEEDS. Interest earnings derived from the investment of proceeds from the sale of the Certificates shall be used along with other certificate proceeds for the Project; provided that after completion of such purpose, if any of such interest earnings remain on hand, such interest earnings shall be deposited in the Interest and Sinking Fund. It is further provided, however,that any interest earnings on certificate proceeds that are required to be rebated to the United States of America pursuant to Section 10 hereof in order to prevent the Certificates from being arbitrage bonds shall be so rebated and not considered as interest earnings for the purposes of this Section.

(i) The Issuer shall be obligated to observe and perform the covenants specified in this Section for so long as, but only for so long as, the Issuer remains an"obligated person" with respect to the Certificates within the meaning of the Rule, except that the Issuer in any event will give the notice required by Subsection(b) hereof of any Certificate calls and defeasance that cause the Issuer to no longer be such an "obligated person".

(b) Except as provided in paragraph(a) above, the holders of Certificates aggregating in principal amount 51% of the aggregate principal amount of then outstanding Certificates which are the subject of a proposed amendment shall have the right from time to time to approve any amendment hereto which may be deemed necessary or desirable by the Issuer; provided, however, that without the consent of 100%of the holders in aggregate principal amount ofthe then outstanding Certificates, nothing herein contained shall permit or be construed to permit amendment of the terms and conditions of this Ordinance or in any of the Certificates so as to: (1) Make any change in the maturity of any of the outstanding Certificates; (2) Reduce the rate of interest borne by any of the outstanding Certificates; (3) Reduce the amount of the principal of,or redemption premium,if any, payable on any outstanding Certificates; 22 (4) Modify the terms of payment of principal or of interest or redemption premium on outstanding Certificates or any of them or impose any condition with respect to such payment; or (5) Change the minimum percentage of the principal amount of any series of Certificates necessary for consent to such amendment.

Such published notice shall briefly set forth the nature of the proposed amendment and shall state that a copy thereof is on file at the office of the Issuer for inspection by all holders of such Certificates. (d) Whenever at any time within one year from the date of publication of such notice the Issuer shall receive an instrument or instruments executed by the holders of at least 51%in aggregate principal amount of all of the Certificates then outstanding which are required for the amendment, which instrument or instruments shall refer to the proposed amendment and which shall specifically consent to and approve such amendment, the Issuer may adopt the amendment in substantially the same form. (e) Upon the adoption of any amendatory Ordinance pursuant to the provisions of this Section, this Ordinance shall be deemed to be modified and amended in accordance with such amendatory Ordinance, and the respective rights, duties, and obligations of the Issuer and all holders of such affected Certificates shall thereafter be determined, exercised, and enforced, subject in all respects to such amendment.

Chapter 1208, Government Code, applies to the issuance of the Certificates and the pledge of the ad valorem taxes granted by the Issuer under Section 5 of this Ordinance and the pledge of the Surplus Revenues under Section 6 of this Ordinance, and such pledge is therefore valid, effective, and perfected.

Box 307 Prosper, Texas 75078 Re: Town of Prosper,Texas Combination Tax and Revenue Certificates of Obligation, Series 2006 Ladies and Gentlemen: The purpose of this engagement letter is to set forth certain matters concerning the services we will perform as bond counsel to the Town of Prosper(the "Issuer") in connection with the issuance of the above-referenced Certificates of Obligation (the "Certificates"). We understand that the Certificates are being issued paying all or a portion of the Town's contractual obligations incurred in connection with(i)constructing and improving the Town's water system, including the construction of an elevated water storage tank and water distribution lines, (ii) acquiring, constructing and equipping municipal park improvements and open space (iii) constructing and improving roads and streets in the Town and related infrastructure,(iv) extending, constructing and improving the Town's sewer system, (v) acquiring land and interests in land as may be required in connection with the purposes described in clauses (i) through (iv), and (vi) paying legal, fiscal, engineering and architectural fees in connection with these projects. We further understand that the Certificates will be secured by a pledge of the receipts of an ad valorem tax levied by the Issuer within the limitation prescribed by law and additionally from the surplus net revenues ofthe Issuer's waterworks and sewer system. We understand that the Certificates will be issued in the amount of$12,000,000. We further understand that the Certificates will be sold by the Town Council of the Issuer(the"Town Council") by negotiated sale on or about August 22, 2006 (the "Sale Date"). A. THE FINANCING As Bond Counsel to the Issuer, we would like for the Town Council to understand how the issuance of the Certificates will be effected. I will briefly describe the procedures and certain applicable law that pertains to the issuance of the Certificates,below. However,you should feel free to call me at any time to discuss any questions that you or your staff may have. Page 1 of 6 (1) The first step in the issuance of the Certificates will be the adoption of a resolution expressing the Issuer's intention to issue the Certificates, providing for the intended use of the Certificate proceeds and describing the sources of payment. The resolution will include a notice that must be published in the local paper on two occasions, with the first publication to be at least 14 days prior to the adoption of the Certificate Ordinance, described below. The publication of the notice gives right to voters of the Issuer to present a petition calling for a referendum on the adoption of the Certificate Ordinance. If no such petition is received from at least five percent of the registered voters of the Issuer prior to the adoption of the Certificate Ordinance, then the Issuer may proceed with the issuance without holding an election. (2) The Certificates will be "ordered to be issued" when and if the Town Council approves an ordinance(the "Ordinance")on the Sale Date. The Ordinance provides for(i)the terms of the Certificates,including the principal amortization schedule and interest rates,(ii)the redemption right of the Issuer with respect to the Certificates, (iii)the Issuer's commitment to levy its debt service tax each year in an amount sufficient to pay the debt service on the Certificates to the extent that the other revenues are not on deposit in the Issuer's Interest and Sinking Fund for the Certificates in amounts sufficient to pay the debt service on the Certificates when the annual tax levy is set,(iv)the sale of the Certificates to the winning bidder, (v)the approval of a paying agent agreement to whom you will make semiannual payments sufficient to pay the debt service on the Certificates, (vi) certain other covenants of the Issuer that are designed to allow the Issuer to issue the Certificates as tax-exempt obligations and (vii)the Issuer's commitment to annually provide information to certain persons that describe the Issuer's financial condition, the status of the Certificates and certain other matters. As you can see, the Ordinance is an omnibus undertaking of the Issuer that is intended to provide for all actions and undertakings that are required for the issuance, sale and delivery of the Certificates. There will be other certificates and letters that will be required to be executed by officers of the Issuer on the Sale Date, but they all spring from, and are authorized by, the Ordinance. (3) As noted above, the Certificates will be sold to the winning bidder in accordance with the provisions of the Ordinance and, in addition, the winning bidder will require that the Issuer make certain representations to the underwriter to the effect that the Issuer is authorized to issue the Certificates and that it has made full disclosure to the Certificate holders of all material information. Therefore,if there are any unusual financial,legal or other circumstances affecting the Issuer which would make such representations or statements made by the Issuer untrue,you should let your Financial Advisor know about them as soon as possible. As a condition to the underwriter paying for the Certificates, they will require this firm to deliver our Bond Counsel opinion to them, through which we will opine that the Certificates are valid obligations of the Issuer and that, assuming ongoing compliance by the Issuer with the provisions of the Ordinance, the interest on the Certificates will be exempt from Federal income taxation. State law will also require the delivery of an opinion of the Texas Attorney General approving the Certificates. (4)The Issuer will offer the Certificates into the public debt markets prior to the time that the Town Council meets to accept the underwriter's offer for the Certificates. Through this process, the Certificates will be "priced," i.e., interest rates and premiums or discounts, if any, Page 2 of 6 for the Certificates will be established. Again, your financial advisor will assist you in the marketing of the Certificates to the underwriter. On the Sale Date, the Town Council will consider the terms offered to the Issuer by the winning bidder based upon the market conditions and other factors that determine interest rates and pricing information. The Issuer, working with its financial advisor and Bond Counsel, will prepare an offering document called an "Official Statement" that contains financial and operating data concerning the Issuer, and information that describes the Certificates. The Issuer is responsible for the information that is contained in the Official Statement to the extent that it describes the Certificates and the Issuer. B. SCOPE OF ENGAGEMENT In this engagement, we expect to perform the following duties: (1) Subject to the completion of proceedings to our satisfaction,render our legal opinion(the "Bond Opinion") regarding the validity and binding effect of the Certificates, the source of payment and security for the Certificates, and the excludability of interest on the Certificates from gross income for Federal income tax purposes. Our Bond Opinion will be delivered by us on the date the Certificates are exchanged for their purchase price (the "Closing"). The Issuer will be entitled to rely on our Bond Opinion. The Bond Opinion will be based on facts and law existing as of its date. In rendering our Bond Opinion, we will rely upon the certified proceedings and other certifications of public officials and other persons furnished to us without undertaking to verify the same by independent investigation, and we will assume continuing compliance by the Issuer with applicable laws relating to the Certificates. During the course of this engagement, we will rely on you to provide us with complete and timely information on all developments pertaining to any aspect of the Certificates and their security. We understand that you will direct members of your staff and other employees of the Issuer to cooperate with us in this regard. (2) Prepare and review documents necessary or appropriate to the authorization,issuance and delivery of the Certificates, coordinate the authorization and execution of such documents, and review enabling legislation. (3) Assist the Issuer in seeking from other governmental authorities such approvals, permissions and exemptions as we determine are necessary or appropriate in connection with the authorization, issuance and delivery of the Certificates, except that we will not be responsible for any required federal or state securities law filings. In this connection, we particularly undertake to assist the Issuer in having the Certificates approved by the Public Finance Division of the Office of the Texas Attorney General, and, following such approval, registered by the Texas Comptroller of Public Accounts. Page 3 of 6 (4) Review legal issues relating to the structure of the Certificate issue. (5) Review those sections of the official statement to be disseminated in connection with the sale of the Certificates that describe the Certificates,the Ordinance pursuant to which they will be issued and the tax-exempt treatment of the interest on the Certificates for purposes of federal income taxation. (6) If requested, assist the Issuer in presenting information to bond rating organizations and providers of credit enhancement relating to legal issues affecting the issuance of the Certificates. (7) Draft the continuing disclosure undertaking of the Issuer. Our duties in this engagement are limited to those expressly set forth above. Unless we are separately engaged in writing to perform other services, our duties do not include any other services, including the following: (1) Preparing requests for tax rulings from the Internal Revenue Service, or no action letters from the Certificates and Exchange Commission. (2) Preparing state securities law memoranda or investment surveys with respect to the Certificates. (3) Drafting state constitutional or legislative amendments. (4) Pursuing test cases or other litigation. (5) Expressing any view as to the creditworthiness of the Issuer or the Certificates. (6) Representing the Issuer in Internal Revenue Service examinations or inquiries, or Certificates and Exchange Commission investigations. (7) Except as described in paragraph(7)above, assisting in the preparation of,or opining on, a continuing disclosure undertaking pertaining to the Certificates or, after Closing, providing advice concerning any actions necessary to assure compliance with any continuing disclosure undertaking. (8) After Closing,providing continuing advice to the Issuer or any other party concerning any actions necessary to assure that interest paid on the Certificates will continue to be excludable from gross income for federal income tax purposes(e.g.,our engagement does not include rebate calculations for the Certificates). (9) Negotiating the terms of, or opining as to, any investment contract. Page 4 of 6 (10) Addressing any other matter not specifically set forth above that is not required to render our Bond Opinion or our disclosure opinion. C. ATTORNEY-CLIENT RELATIONSHIP Upon execution of this engagement letter, the Issuer will be our client and an attorney-client relationship will exist between us. We further assume that all other parties in this transaction understand that we represent only the Issuer in this transaction,we are not counsel to any other party, and we are not acting as an intermediary among the parties. Our services as bond counsel are limited to those contracted for in this letter; the Issuer's execution of this engagement letter will constitute an acknowledgment of those limitations. Our representation of the Issuer will not affect, however, our responsibility to render an objective Bond Opinion. Our representation of the Issuer and the attorney-client relationship created by this engagement letter will be concluded upon issuance of the Certificates. Nevertheless, subsequent to Closing, we will mail the appropriate Internal Revenue Service Form 8038, prepare and distribute to the participants in the transaction a transcript of the proceedings pertaining to the Certificates. D. CONFLICTS As you are aware,our firm represents many political subdivisions and investment banking firms, among others, who do business with political subdivisions. It is possible that during the time that we are representing the Issuer, one or more of our present or future clients will have transactions with the Issuer. It is also possible that we may be asked to represent, in an unrelated matter, one or more of the entities involved in the issuance of the Certificates. We do not believe such representation, if it occurs, will adversely affect our ability to represent you as provided in this letter, either because such matters will be sufficiently different from the issuance of the Certificates so as to make such representations not adverse to our representation of you, or because the potential for such adversity is remote or minor and outweighed by the consideration that it is unlikely that advice given to the other client will be relevant to any aspect of the issuance of the Certificates. Execution of this letter will signify the Issuer's consent to our representation of others consistent with the circumstances described in this paragraph. A CONFLICT OF INTEREST QUESTIONNAIRE COMPLETED IN THE FORM PRESCRIBED BY CHAPTER 176 OF THE TEXAS LOCAL GOVERNMENT CODE, AS AMENDED, WILL BE PROVIDED TO THE ISSUER E. FEES Based upon: (i) our current understanding of the terms, structure, size and schedule of the financing represented by the Certificates;(ii)the duties we will undertake pursuant to this engagement letter;(iii)the time we anticipate devoting to the financing;and(iv)the responsibilities we will assume in connection therewith, our fee for Bond Counsel services will be $5,000 plus .001 times the principal amount of the Bonds that is in excess of$1,000,000. In addition,we will be reimbursed for all travel costs, photocopying, deliveries,long distance telephone charges, telecopier charges and all other expenses. Our fee will be billed after the Closing. If the financing is not consummated, we understand and agree that we will not be paid. In accordance with the terms of the Certificate Page 5 of 6 Ordinance, the Issuer will provide the filing fee of the Texas Attorney General to Bond Counsel on a timely basis to permit the filing of the transcript of proceedings for the Certificates so that the Certificates may be approved by the Attorney General in time to meet the closing date of September 25, 2006. F. RECORDS At your request, papers and property furnished by you will be returned promptly upon receipt of payment for outstanding fees and client charges. Our own files, including lawyer work product, pertaining to the transaction will be retained by us.
