Ladies and Gentlemen:

First Horizon Asset Securities Inc., a corporation organized and existing under the laws of the State of Delaware (the “Company”), may offer for sale to you and to each of the other several underwriters, if any, participating in an underwriting syndicate managed by you, from time to time its Mortgage Pass-Through Certificates evidencing interests in pools of mortgage loans (the “Certificates”). The Certificates may be issued in various series, and within each series, in one or more classes, in one or more offerings on terms determined at the time of sale (each such series, a “Series” and each such class, a “Class”). Each Series of the Certificates will be issued under a separate Pooling and Servicing Agreement (each, a “Pooling and Servicing Agreement”) to be dated as of the respective cut-off date (each, a “Cut-off Date”) among the Company, as depositor, First Horizon Home Loan Corporation, as master servicer, and The Bank of New York, as trustee (the “Trustee”). Capitalized terms used but not defined herein shall have the meanings given to them in the related Pooling and Servicing Agreement.

The Certificates issued under each Pooling and Servicing Agreement will represent the entire beneficial ownership interest in a trust fund (the “Trust Fund”) established by such Pooling and Servicing Agreement. The assets of each Trust Fund will consist primarily of (i) one or more pools of conventional, fixed rate, first lien, fully amortizing, one- to four-family residential mortgage loans (the “Mortgage Loans”) having the original terms to maturity specified in the related Terms Agreement referred to hereinbelow, (ii) mortgage pass-through securities issued or guaranteed by Xxxxxx Xxx, Xxxxxx Xxx or Xxxxxxx Mac, or (iii) private mortgage-backed securities backed by first lien mortgage loans secured by one- to four-family residential properties or participations therein. If so specified in the related Terms Agreement, one or more elections may be made to treat the assets of each Trust Fund as a real estate mortgage investment conduit (each, a “REMIC”) for federal income tax purposes.

Whenever the Company determines to make an offering of Certificates (each, a “Certificate Offering”) pursuant to this Agreement through you, it will enter into an agreement (the “Terms Agreement”) providing for the sale of specified Classes of Offered Certificates (as defined below) to, and the purchase and public offering thereof by, you and such other underwriters, if any, selected by you as have authorized you to enter into such Terms Agreement on their behalf (the underwriters in any such Terms Agreement being referred to herein as “Underwriters,” which term shall include you whether acting alone in the sale of any Series of Certificates or as a member of the underwriting syndicate). Each such Certificate Offering that the Company elects to make pursuant to this Agreement shall be governed by this Agreement, as

supplemented by the related Terms Agreement. Each Terms Agreement, which shall be substantially in the form of Exhibit A hereto, shall specify, among other things, the Classes of Certificates to be purchased by the Underwriters (the “Offered Certificates”), the names of the Underwriters participating in such offering (subject to substitution as provided in Section 16 hereof) and the principal amount of the Offered Certificates which each severally agrees to purchase, the names of such other Underwriters, if any, acting as co-managers with you in connection with each offering, the principal balance or balances of the Offered Certificates, each subject to any stated variance, and the price or prices at which such Offered Certificates are to be purchased by the Underwriters from the Company.

1. Representations and Warranties. The Company represents and warrants to and agrees with each Underwriter, as of the date of the related Terms Agreement, that:

(a) The registration statement specified in the related Terms Agreement, on Form S-3, including a prospectus, has been filed with the Securities and Exchange Commission (the “Commission”) for the registration under the Securities Act of 1933, as amended (the “Act”), of mortgage pass-through certificates issuable in series, which registration statement has been declared effective by the Commission. Such registration statement, as amended to the date of the related Terms Agreement, including any documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Act which were filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on or before the effective date of the Registration Statement, is hereinafter called the “Registration Statement,” and such prospectus, as such prospectus is supplemented by a prospectus supplement relating to the Offered Certificates of the related Series, each in the form first filed after the date of the related Terms Agreement pursuant to Rule 424(b) under the Act, including any documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Act which were filed under the Exchange Act on or before the date of such prospectus supplement (other than any such incorporated documents that relate to Collateral Term Sheets (as defined herein))(such prospectus supplement, including such incorporated documents (other than those that relate to Collateral Term Sheets), in the form first filed after the date of the related Terms Agreement pursuant to Rule 424(b) is hereinafter called the “Prospectus Supplement”), is hereinafter called the “Prospectus”. Any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Prospectus or the Prospectus Supplement shall be deemed to refer to and include the filing of any document under the Exchange Act after the effective date of the Registration Statement or the issue date of the Prospectus or Prospectus Supplement, as the case may be, deemed to be incorporated therein by reference pursuant to Item 12 of Form S-3 under the Act.

(b) The related Registration Statement, at the time it became effective, and the Prospectus contained therein, and any amendments thereof and supplements thereto filed prior to the date of the related Terms Agreement, conformed in all material respects to the requirements of the Act and the rules and regulations of the Commission thereunder; on the date of the related Terms Agreement and on each Closing Date (as defined in Section 3 below), the related Registration Statement and the related Prospectus, and any amendments thereof and supplements thereto, will conform in all material respects to the

requirements of the Act and the rules and regulations of the Commission thereunder; such Registration Statement, at the time it became effective, did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; such Prospectus, on the date of any filing pursuant to Rule 424(b) and on each Closing Date, will not include any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they are made, not misleading; and the detailed description (each, a “Detailed Description”) filed in connection with any Pre-Funding Arrangement referred to in such Prospectus, on each closing date relating to the purchase of the related Subsequent mortgage loans and the date of any filing thereof under cover of Form 8-K, will not include any untrue statement of a material fact or omit to state any information which such Prospectus states will be included in such Detailed Description; provided, however, that the Company makes no representations or warranties as to the information contained in or omitted from (A) such Registration Statement or such Prospectus (or any supplement thereto) in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter specifically for use in the preparation thereof or (B) any Current Report (as defined in Section 5(b) below), or in any amendment thereof or supplement thereto, incorporated by reference in such Registration Statement or such Prospectus (or any amendment thereof or supplement thereto).

(c) The Certificates of the related Series will conform to the description thereof contained in the related Prospectus; will each, if rated at the time of issuance in one of the two highest rating categories by a nationally recognized statistical rating organization, be when issued a “mortgage related security” as such term is defined in Section 3(a)(41) of the Exchange Act, and will each on the related Closing Date be duly and validly authorized, and, when validly executed, countersigned, issued and delivered in accordance with the related Pooling and Servicing Agreement and sold to the Underwriters as provided herein and in the related Terms Agreement, will each be validly issued and outstanding and entitled to the benefits of the related Pooling and Servicing Agreement.

(d) Neither the issuance nor sale of the Certificates of the related Series nor the consummation of any other of the transactions herein contemplated, nor the fulfillment of the terms hereof or of the related Terms Agreement, will conflict with any statute, order or regulation applicable to the Company of any court, regulatory body, administrative agency or governmental body having jurisdiction over the Company or with any organizational document of the Company or any instrument or any agreement under which the Company is bound or to which it is a party.

(e) This Agreement and the related Terms Agreement have been duly authorized, executed and delivered by the Company.

(f) At or prior to the related Closing Date, the Company will have entered into the related Pooling and Servicing Agreement and, assuming the due authorization, execution and delivery thereof by the other parties thereto, such Pooling and Servicing Agreement (on such Closing Date) will constitute the valid and binding agreement of the

Company enforceable in accordance with its terms, subject as to enforceability, to bankruptcy, insolvency, reorganization or other similar laws affecting creditors’ rights and to general principles of equity (regardless of whether the enforceability of such Pooling and Servicing Agreement is considered in a proceeding in equity or at law).

2. Purchase and Sale. Subject to the execution of the Terms Agreement for a particular Certificate Offering and subject to the terms and conditions and in reliance upon the representations and warranties set forth in this Agreement and such Terms Agreement, the Company agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Company, the respective original principal amounts of the Offered Certificates set forth in the applicable Terms Agreement opposite the name of such Underwriter, plus any additional original principal amount of Offered Certificates which such Underwriter may be obligated to purchase pursuant to Section 16 hereof at the purchase price therefor set forth in such Terms Agreement (the “Purchase Price”).

The parties hereto agree that settlement for all securities sold pursuant to this Agreement and the applicable Terms Agreement shall take place on the settlement date agreed upon at the time of the related transaction and set forth as the “Closing Date” in such Terms Agreement and not as set forth in Rule 15c6-1(a) of the Exchange Act.

3. Delivery and Payment. Delivery of and payment for the Offered Certificates of a Series shall be made at the offices of Xxxxxxx & Xxxxx L.L.P., Dallas, Texas, at 10:00 A.M., Dallas time, on the Closing Date specified in the related Terms Agreement, which date and time may be postponed by agreement between you and the Company (such date and time being herein called the “Closing Date”). Delivery of such Offered Certificates shall be made to you for the respective accounts of the Underwriters against payment of the Purchase Price thereof to or upon the order of the Company by wire transfer in federal or other immediately available funds or by check payable in federal funds, as the Company shall specify no later than five full business days prior to such Closing Date. Unless delivery is made through the facilities of The Depository Trust Company, the Offered Certificates shall be registered in such names and in such authorized denominations as you may request not less than two full business days in advance of each Closing Date.

The Company agrees to notify you at least two business days before each Closing Date of the exact principal balance evidenced by the Offered Certificates and to have such Offered Certificates available for inspection, checking and packaging in Dallas, Texas, no later than 12:00 noon on the business day prior to such Closing Date.

4. Offering by the Underwriter. It is understood that the Underwriters propose to offer the Offered Certificates of the related Series for sale to the public as set forth in the related Prospectus.

5. Agreements. The Company agrees with each Underwriter that:

(a) The Company will cause the Prospectus as supplemented by a Prospectus Supplement relating to the Offered Certificates to be filed pursuant to Rule 424 under the Act and will promptly advise you when such Prospectus as so supplemented has been so

filed, and prior to the termination of the Certificate Offering to which such Prospectus relates also will promptly advise you (i) when any amendment to the related Registration Statement specifically relating to such Offered Certificates shall have become effective or any further supplement to such Prospectus has been filed, (ii) of any request by the Commission for any amendment of such Registration Statement or Prospectus or for any additional information, (iii) of the issuance by the Commission of any stop order suspending the effectiveness of such Registration Statement or the institution or threatening of any proceeding for that purpose and (iv) of the receipt by the Company of any written notification with respect to the suspension of the qualification of such Offered Certificates for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose. The Company will not file any amendment of the related Registration Statement or supplement to the related Prospectus (other than any amendment or supplement specifically relating to one or more Series of mortgage pass-through certificates other than the Series that includes the related Offered Certificates or any Exchange Act filings other than Current Reports) unless the Company has furnished you and your counsel with a copy for your respective review prior to filing and you have consented to such filing. The Company will use its best efforts to prevent the issuance of any such stop order and, if issued, to obtain as soon as possible the withdrawal thereof.

(b) The Company will cause any Computational Materials and any Structural Term Sheets (each as defined in Section 8 below) with respect to the Offered Certificates of a Series that are delivered by any Underwriter to the Company pursuant to Section 8 to be filed with the Commission on a Current Report on Form 8-K (each such filing of such materials, a “Current Report”) pursuant to Rule 13a-11 under the Exchange Act on the business day immediately following the later of (i) the day on which such Computational Materials and Structural Term Sheets are delivered to counsel for the Company by such Underwriter, and (ii) the date on which this Agreement is executed and delivered. The Company will cause any Collateral Term Sheet (as defined in Section 9 below) with respect to the Offered Certificates of a Series that is delivered by any Underwriter to the Company in accordance with the provisions of Section 9 to be filed with the Commission on a Current Report pursuant to Rule 13a-11 under the Exchange Act on the business day immediately following the day on which such Collateral Term Sheet is delivered to counsel for the Company by such Underwriter. Each such Current Report shall be incorporated by reference in the related Prospectus and the related Registration Statement.

(c) If, at any time when a prospectus relating to the Offered Certificates of a Series is required to be delivered under the Act, any event occurs as a result of which the related Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in light of the circumstances under which they were made not misleading, or if it shall be necessary at any time to amend or supplement the related Prospectus to comply with the Act or the rules thereunder, the Company promptly shall prepare and file with the Commission, subject to the penultimate sentence of paragraph (a) of this Section 5, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance.

(d) The Company will furnish to each Underwriter and counsel for the Underwriters, without charge, as many signed copies of the related Registration Statement (including exhibits thereto) and, so long as delivery of a prospectus by such Underwriter or dealer may be required by the Act, as many copies of the related Prospectus and any amendments or supplements thereto as such Underwriter may reasonably request.

(e) The Company will furnish such information, execute such instruments and take such actions as may be reasonably requested by you to qualify the Offered Certificates of a Series for sale under the laws of such jurisdictions as the Underwriter may designate, to maintain such qualifications in effect so long as required for the distribution of such Offered Certificates and to determine the legality of such Offered Certificates for purchase by institutional investors; provided, however, that the Company shall not be required to qualify to do business in any jurisdiction where it is not qualified on the date of the related Terms Agreement or to take any action which would subject it to general or unlimited service of process in any jurisdiction in which it is not, on the date of the related Terms Agreement, subject to such service of process.

(f) So long as the Offered Certificates of a Series are outstanding, the Company will furnish to each Underwriter, upon request, copies of the annual independent public accountants’ servicing report furnished to the Trustee pursuant to the related Pooling and Servicing Agreement.

(v) such counsel confirms that the related Registration Statement is effective under the Act and, to the best of such counsel’s knowledge, no stop order with respect thereto has been issued, and no proceeding for that purpose has been instituted or threatened by the Commission; such Registration Statement (except the financial statements and schedules and other financial and statistical data included therein and the documents incorporated by reference therein, as to

which such counsel need express no view), at the time it became effective and the related Prospectus (except the financial statements and schedules, the other financial and statistical data included therein and the documents incorporated by reference therein), as of the date of the Prospectus Supplement conformed in all material respects to the requirements of the Act and the rules and regulations thereunder; and no information has come to the attention of such counsel that causes it to believe that (A) such Registration Statement (except the financial statements and schedules and the other financial and statistical data included therein and the documents incorporated by reference therein, as to which such counsel need express no view) at the time it became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or (B) such Prospectus or any amendment or supplement thereto (except the financial statements and schedules and the other financial and statistical data included therein), as of the date of the Prospectus Supplement, or at the related Closing Date, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(vi) the statements set forth under the heading “Description of the Certificates” in the related Prospectus, insofar as such statements purport to summarize certain provisions of the related Pooling and Servicing Agreement and the related Offered Certificates, provide a fair summary of such provisions;

7. Indemnification and Contribution.

(a) The Company and First Horizon Home Loan Corporation jointly and severally agree to indemnify and hold harmless each Underwriter and each person who controls any Underwriter within the meaning of the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act, or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement relating to the Offered Certificates of the applicable Series as it became effective or in any amendment or supplement thereof, or in such Registration Statement or the related Prospectus, or in any amendment or supplement thereof, or in any Detailed Description referred to in such Prospectus (or the related prospectus Supplement) or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agree to reimburse each such indemnified party for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that (i) neither the Company nor First Horizon Home Loan Corporation will be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein (A) in reliance upon and in conformity with written information furnished to the Company or First Horizon Home Loan Corporation, as the case may be, as herein stated by or on behalf of any Underwriter specifically for use in connection with the preparation thereof or (B) in any Current Report or any amendment or supplement thereof, except to the extent that any untrue statement or alleged untrue statement therein or omission therefrom results (or is alleged to have resulted) directly from an error (a “Mortgage Pool Error”) in the information concerning the characteristics of the Mortgage Loans furnished by the Company or First Horizon Home Loan Corporation, as the case may be, to any Underwriter in writing or by electronic transmission that was used in the preparation of either (x) any Computational Materials or ABS Term Sheets (or amendments or supplements thereof) included in such Current Report (or amendment or supplement thereof) or (y) any written or electronic materials furnished to prospective investors on which the Computational Materials or ABS Term Sheets (or amendments or supplements) were based and (ii) such indemnity with respect to any Corrected Statement (as defined below) in such Registration Statement or the related Prospectus (or any amendment or supplement thereto) shall not inure to the benefit of any Underwriter (or any person controlling such Underwriter) from whom the person asserting any loss, claim, damage or liability purchased the Certificates of the related Series that are the subject thereof if such person did not receive a copy of an amendment or supplement to such Registration Statement or the related Prospectus at or prior to the confirmation of the sale of such Certificates and the untrue statement or omission of a material fact contained in such Registration Statement or the related Prospectus (or any amendment or supplement thereto) was corrected (a “Corrected Statement”) in such other amendment or supplement and such amendment or supplement was furnished by the Company or First Horizon Home Loan Corporation, as the case may be, to such Underwriter prior to the

delivery of such confirmation. This indemnity agreement will be in addition to any liability that the Company and First Horizon Home Loan Corporation may otherwise have.

(b) Each Underwriter severally agrees to indemnify and hold harmless the Company, each of its directors, each of its officers, and each person or entity (including each of its directors and officers) who controls the Company within the meaning of the Act or the Exchange Act, to the same extent as the foregoing indemnities from the Company and First Horizon Home Loan Corporation to the Underwriter, but only with reference to (A) written information furnished to the Company by or on behalf of such Underwriter specifically for use in the preparation of the documents referred to in the foregoing indemnity with respect to the related Series, or (B) any Computational Materials or ABS Term Sheets (or amendments or supplements thereof) furnished to the Company by such Underwriter pursuant to Section 8 or Section 9 and incorporated by reference in such Registration Statement or the related Prospectus or any amendment or supplement thereof (except that no such indemnity shall be available for any losses, claims, damages or liabilities, or actions in respect thereof, resulting from any Mortgage Pool Error). This indemnity agreement will be in addition to any liability that the Underwriters may otherwise have. The Company acknowledges, unless otherwise specified in writing by an Underwriter, that the statements set forth in the first sentence of the last paragraph appearing on the cover page of the related Prospectus Supplement as such statements relate to such Offered Certificates and the second sentence of the first paragraph and the first sentence of the second paragraph in each case under the heading “Method of Distribution” in such Prospectus Supplement as such statements relate to such Offered Certificates constitute the only information furnished in writing by or on behalf of such Underwriter for inclusion in the related Prospectus (other than any Computational Materials or ABS Term Sheets (or amendments or supplements thereof) furnished to the Company by such Underwriter), and such Underwriter confirms that such statements are correct.

(c) Promptly after receipt by an indemnified party under Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under this Section 7, except to the extent that the omission to so notify the indemnifying party causes or exacerbates a loss. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and to the extent that it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof, with counsel satisfactory to such indemnified party; provided, however, that if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assert such

legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 7 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel approved by the indemnified party in the case of subparagraph (a) or (b), representing the indemnified parties under subparagraph (a) or (b), who are parties to such action), (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party; and except that, if clause (i) or (iii) is applicable, such liability shall be only in respect of the counsel referred to in such clause (i) or (iii).

(d) If the indemnification provided for in paragraph (a) or (b) of this Section 7 is due in accordance with its terms but is for any reason held by a court to be unavailable from the Company, First Horizon Home Loan Corporation or any Underwriter, on grounds of policy or otherwise, or if the indemnified party failed to give notice under paragraph (c) of this Section 7 in respect of a claim otherwise subject to indemnification in accordance with paragraph (a) or (b) of this Section 7, the Company, First Horizon Home Loan Corporation and such Underwriter shall contribute to the aggregate losses, claims, damages and liabilities (including legal and other expenses reasonably incurred in connection with investigating or defending same) to which the Company, First Horizon Home Loan Corporation and such Underwriter may be subject, as follows:

(i) in the case of any losses, claims, damages and liabilities (or actions in respect thereof) which do not arise out of or are not based upon any untrue statement or omission of a material fact in any Computational Materials or ABS Term Sheets (or any amendments or supplements thereof) or in any written or electronic materials distributed to prospective investors on which the Computational Materials are based, in such proportion so that such Underwriter is responsible for that portion represented by the difference between the proceeds to the Company in respect of the Offered Certificates appearing on the cover page of the Prospectus Supplement for the related Series and the total proceeds received by such Underwriter from the sale of such Offered Certificates (the “Underwriting Discount”), and the Company and First Horizon Home Loan Corporation are jointly and severally responsible for the balance; provided, however, that in no case shall such Underwriter be responsible under this subparagraph (i) for any amount in excess of such Underwriting Discount applicable to the Offered Certificates purchased by such Underwriter pursuant to this Agreement and the related Terms Agreement; and

(ii) in the case of any losses, claims, damages and liabilities (or actions in respect thereof) which arise out of or are based upon any untrue statement or omission of a material fact in any Computational Materials or ABS Term Sheets (or any amendments or supplements thereof) or in any written or electronic materials distributed to prospective investors on which the Computational Materials are based, in such proportion as is appropriate to reflect the relative fault of the Company or First Horizon Home Loan Corporation, as the case may be, on the one hand and such Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof) as well as any other relevant equitable considerations; provided, however, that in no case shall such Underwriter be responsible under this subparagraph (ii) for any amount in excess of the Underwriting Discount applicable to the Offered Certificates purchased by such Underwriter pursuant to this Agreement and the related Terms Agreement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact in such Computational Materials or ABS Term Sheets (or any amendments or supplements thereof or such written or electronic materials) results from information prepared by the Company or First Horizon Home Loan Corporation, as the case may be, on the one hand or such Underwriter on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

Notwithstanding anything to the contrary in this Section 7(d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act shall have the same rights to contribution as such Underwriter, and each person who controls the Company or First Horizon Home Loan Corporation, as the case may be, within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company or First Horizon Home Loan Corporation, as the case may be, shall have the same rights to contribution as the Company or First Horizon Home Loan Corporation, as the case may be, subject in each case to the immediately preceding sentence of this paragraph (d).

8. Computational Materials and Structural Term Sheets.

Each delivery of Computational Materials and Structural Term Sheets to the Company pursuant to this paragraph (a) shall be effected by delivering four copies of such materials to counsel for the Company on behalf of the Company at the address specified in Section 3 hereof and one copy of such materials to the Company.

(b) If, at any time when a prospectus relating to the Offered Certificates of a Series is required to be delivered under the Act, it shall be necessary to amend or supplement the related Prospectus as a result of an untrue statement of a material fact contained in any Computational Materials or Structural Term Sheets provided by any Underwriter pursuant to this Section 8 or the omission to state therein a material fact required, when considered in conjunction with the related Prospectus and Prospectus Supplement, to be stated therein or necessary to make the statements therein, when read in conjunction with the related Prospectus and Prospectus Supplement, not misleading, or if it shall be necessary to amend or supplement any Current Report relating to any Computational Materials or Structural Term Sheets to comply with the Act or the rules thereunder, such Underwriter shall prepare and furnish to the Company for filing with the Commission an amendment or supplement which will correct such statement or omission or an amendment or supplement which will effect such compliance.

(c) Each Underwriter shall cause Deloitte & Touche LLP to furnish to the Company a letter, dated as of the date on which you deliver any Computational Materials or Structural Term Sheets to the Company pursuant to Section 8(a), in form and substance satisfactory to the Company, stating in effect that they have verified the mathematical accuracy of any calculations performed by such Underwriter and set forth in such Computational Materials or Structural Term Sheets, as applicable.

9. Collateral Term Sheets.

(a) On the business day immediately following the date on which any Collateral Term Sheet (as defined in the PSA Letter) was first delivered to a prospective investor in such Offered Certificates, each Underwriter shall deliver to the Company five complete copies of all materials provided by such Underwriter to prospective investors in the Offered Certificates that constitute “Collateral Term Sheets.” Each delivery of a Collateral Term Sheet to the Company pursuant to this paragraph (a) shall be effected by delivering four copies of such materials to counsel for the Company on behalf of the Company at the address specified in Section 3 hereof and one copy of such materials to the Company. (Collateral Term Sheets and Structural Term Sheets are, together, referred to herein as “ABS Term Sheets.”)

(b) If, at any time when a prospectus relating to the Offered Certificates of a Series is required to be delivered under the Act, it shall be necessary to amend or

supplement the related Prospectus as a result of an untrue statement of a material fact contained in any Collateral Term Sheets provided by an Underwriter pursuant to this Section 9 or the omission to state therein a material fact required, when considered in conjunction with the related Prospectus and Prospectus Supplement, to be stated therein or necessary to make the statements therein, when read in conjunction with the related Prospectus and Prospectus Supplement, not misleading, or if it shall be necessary to amend or supplement any Current Report relating to any Collateral Term Sheets to comply with the Act or the rules thereunder, such Underwriter shall prepare and furnish to the Company for filing with the Commission an amendment or supplement which will correct such statement or omission or an amendment or supplement which will effect such compliance.

The agreements, representations, warranties, indemnities and other statements of the Company (or First Horizon Home Loan Corporation, as the case may be) or its officers and of each Underwriter set forth in or made pursuant to this Agreement and the related Terms Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company (or First Horizon Home Loan Corporation, as the case may be) or any of the officers, directors or controlling persons referred to in Section 7 hereof, and will survive delivery of and payment for the related Offered Certificates. The provisions of Section 7 hereof shall survive the termination or cancellation of this Agreement and the related Terms Agreement.
