The Trustee Fee shall be paid by the Depositor and not from Trust Property. The Trustee shall bear all Ordinary Expenses. Failure by the Depositor to pay such amount shall not entitle the Trustee to any payment or reimbursement from the Trust, nor shall such failure release the Trustee from the duties it is required to perform under the Trust Agreement. (b) Extraordinary Expenses shall not be paid out of the Trust Property unless all the holders of the Class A-1 Certificates and Class A-2 Certificates then outstanding have directed the Trustee to incur such Extraordinary Expenses. The Trustee may incur other Extraordinary Expenses if any lesser percentage of the Certificateholders requesting such action pursuant hereto reimburse the Trustee for the cost thereof from their own funds in advance. If Extraordinary Expenses are not approved unanimously as set forth in the first sentence of this Section 6(b), such Extraordinary Expenses shall not be an obligation of the Trust, and the Trustee shall not file any claim against the Trust therefor notwithstanding failure of Certificateholders to reimburse the Trustee. Section 7. Optional Call; Optional Exchange. (a) On (A) any Distribution Date, (B) any date on which a tender offer for some or all of the Underlying Securities is consummated or (C) any date on which the Underlying Securities are to be redeemed by the Underlying Securities Issuer, any holder of Class A-1 Certificates, 14 Class A-2 Certificates and the related Call Warrants, if Call Warrants related to such Certificates are outstanding, may exchange such Certificates and, if applicable, Call Warrants, for a distribution of Underlying Securities representing the same percentage of the Underlying Securities as such Certificates represent of all outstanding Certificates. On any Call Date, any Warrant Holder may exchange Called Certificates for a distribution of Underlying Securities representing the same percentage of Underlying Securities as such Called Certificates represent of all outstanding Certificates; provided that any such exchange shall either (x) result from an exercise of all Call Warrants owned by such Warrant Holder or (y) occur on a Call Date on which such Warrant Holder, alone or together with one or more other Warrant Holders, shall exchange Called Certificates relating to Underlying Securities having an aggregate principal amount equal to or in excess of the product of (i) 0.1 and (ii) the aggregate principal amount of the Underlying Securities deposited into the Trust on the Closing Date. (b) The following conditions shall apply to any Optional Exchange. (i) A notice specifying the number of Certificates being surrendered and the Optional Exchange Date shall be delivered to the Trustee no less than 5 days (or such shorter period acceptable to the Trustee) but not more than 30 days before the Optional Exchange Date; provided that for an Optional Exchange to occur on a Call Date, unless otherwise specified therein, the Call Notice shall be deemed to be the notice required hereunder. (ii) Certificates and, if applicable, the Call Warrants, shall be surrendered to the Trustee no later than 10:00 a.m. (New York City time) on the Optional Exchange Date; provided that for an Optional Exchange to occur on a Call Date, payment of the Call Price to the Warrant Agent pursuant to Section 1.1(a)(iii) of the Warrant Agent Agreement shall satisfy the requirement to surrender Certificates. (iii) Class A-1 Certificates and Class A-2 Certificates representing a like percentage of all Class A-1 Certificates and Class A-2 Certificates shall be surrendered. (iv) The Trustee shall have received an opinion of counsel stating that the Optional Exchange would not cause the Trust to be treated as an association or publicly traded partnership taxable as a corporation for federal income tax purposes. (v) If the Certificateholder is the Depositor or any Affiliate of the Depositor, (1) the Trustee shall have received a certification from the Certificateholder that any Certificates being surrendered have been held for at least six months, and (2) the Certificates being surrendered may represent no more than 5% (or 25% in the case of Certificates acquired by the Underwriters but never distributed to investors) of the then outstanding Certificates. (vi) The Trustee shall not be obligated to determine whether an Optional Exchange complies with the applicable provisions for exemption under Rule 3a-7 of the Investment Company Act of 1940, as amended, or the rules or regulations promulgated thereunder. 15 (vii) The provisions of Section 4.07 of the Standard Terms shall not apply to an Optional Exchange pursuant to this Section 7(b). This Section 7(b) shall not provide any person with a lien against, an interest in or a right to specific performance with respect to the Underlying Securities; provided that satisfaction of the conditions set forth in this Section 7(b) shall entitle the Certificateholder or Warrant Holder, as applicable, to a distribution thereof. (viii) The aggregate principal amount of Certificates exchanged in connection with any Optional Exchange pursuant to this Section shall be in an amount that will entitle the Certificateholders thereof to Underlying Securities in an even multiple of the minimum denomination of such Underlying Securities. (ix) In the event such Optional Exchange shall occur prior to the Distribution Date in August 2003, the Certificateholders shall have paid to the Trustee, for distribution to the Depositor, on the Optional Exchange Date an amount equal to the sum obtained by multiplying the amount of accrued interest on the Underlying Securities from February 11, 2003 through, but excluding, the Closing Date by a fraction, the numerator of which shall be the number of Certificates being exchanged on such Optional Exchange Date and the denominator of which shall be the total number of Certificates. (c) Concurrently with the execution of this Series Supplement, the Trustee, on behalf of the Trust, shall execute the Warrant Agent Agreement and the Call Warrants, dated as of the date hereof and substantially in the form of Exhibit B hereto, initially evidencing all of the Call Warrants. The Trustee shall perform the Trust's obligations under the Warrant Agent Agreement and the Call Warrants in accordance with their respective terms. (d) Call Warrants may be exercised by the Warrant Holder in whole or in part on any Call Date. In addition to the conditions set forth in Section 1.1 of the Warrant Agent Agreement, the following conditions shall apply to any Optional Call. (i) An opinion of counsel to the Warrant Holder shall have been delivered to the Rating Agencies, in form satisfactory to the Rating Agencies, indicating that payment of the Call Price shall not be recoverable as a preferential transfer or fraudulent conveyance under the United States Bankruptcy Code. Such opinion may contain customary assumptions and qualifications. (ii) The Warrant Holder shall have provided a certificate of solvency to the Trustee. (iii) Upon receipt of a Call Notice, the Trustee shall provide a conditional call notice to the Depository not less than 3 Business Days prior to the Call Date. (iv) Delivery of a Call Notice does not give rise to an obligation on the part of the Warrant Holder to pay the Call Price. If, by 10:00 a.m. (New York City time) on the Call Date, the Warrant Holder has not paid the Call Price, except in connection with a Call Notice relating to a tender offer for or redemption of the Underlying Securities, then the Call Notice shall automatically expire and none of the Warrant Holder, the Warrant Agent or the Trustee shall have any obligation with respect to the Call Notice. The 16 expiration of a Call Notice shall in no way affect the Warrant Holder's right to deliver a Call Notice at a later date. The Call Price for a call in connection with a tender offer or redemption shall be deducted from the proceeds of a tender offer or redemption by the Trust pursuant to Section 7(g)(iii) or Section 7(h)(iii), as applicable. (v) Subject to receipt of the Call Price, the Trustee shall pay the applicable portion of the Call Price to the Class A-1 and Class A-2 Certificateholders on the Call Date. The Call Price for each Class of Certificates in respect of partial calls shall be allocated pro rata to the Certificateholders of such Class. (vi) The Trustee shall not consent to any amendment or modification of this Agreement (including the Standard Terms) which would adversely affect the Warrant Holders (including, without limitation, any alteration of the timing or amount of any payment of the Call Price or any other provision of this Agreement in a manner adverse to the Warrant Holders) without the prior written consent of 100% of the Warrant Holders. For purposes of this clause, no amendment, modification or supplement required to provide for any purchase by the Trustee of additional Underlying Securities and authentication and delivery by the Trustee of additional Certificates and Call Warrants pursuant to Section 3(d) shall be deemed to adversely affect the Warrant Holders. (vii) The Trustee shall not be obligated to determine whether an Optional Call complies with the applicable provisions for exemption under Rule 3a-7 of the Investment Company Act of 1940, as amended, or the rules or regulations promulgated thereunder. (e) This Section 7 shall not provide the Warrant Holder with a lien against, an interest in or a right to specific performance with respect to the Underlying Securities; provided that satisfaction of the conditions set forth in Section 7(b) shall entitle the Certificateholders or the Warrant Holders, as applicable, to a distribution of the Underlying Securities. (f) The rights of the Certificateholders under the Trust Agreement and the Certificates are limited by the terms, provisions and conditions of the Trust Agreement, the Warrant Agent Agreement and the Call Warrants with respect to the exercise of the Call Warrants by the Warrant Holder. The Certificateholders, by their acceptance of Certificates, covenant and agree to tender any and all Called Certificates to the Trustee upon the Warrant Holder's exercise of Call Warrants and payment of the Call Price for such Certificates in accordance with the provisions hereof and of the Warrant Agent Agreement. (g) (i) If the Trustee receives notice of a tender offer for some or all of the Underlying Securities, the Trustee shall within one Business Day notify the Warrant Agent and forward to the Warrant Agent copies of all materials received by the Trustee in connection therewith. If the Trustee receives a Call Notice from any Warrant Holder no later than five Business Days prior to the expiration of the tender offer acceptance period that such Warrant Holder desires to exercise all or a portion of its Call Warrants in connection with the consummation of any such tender offer, then the Trustee shall tender, in compliance with the tender offer requirements, an amount of Underlying Securities equal to the amount of Underlying Securities that would be distributable to the Warrant Holder with respect to an Optional 17 Exchange of the Called Certificates called by such Warrant Holder; provided that any Optional Call or Optional Exchange undertaken in connection with any such tender offer shall be subject to the provisions of Section 7 hereof. (ii) The Call Date and Optional Exchange Date for any exercise of Call Warrants in connection with a tender offer shall be deemed to be the Business Day on which such Underlying Securities are accepted for payment and paid for. (iii) The Call Price shall be deducted from the tender offer proceeds and paid to Certificateholders in connection with Section 7(d)(v), and the excess of the tender offer proceeds over the Call Price shall be paid to the exercising Warrant Holders pro rata in respect to their proportionate exercises of Call Warrants or, if the Call Price exceeds the tender offer proceeds, the amount of such excess shall be paid by the exercising Warrant Holders pro rata in respect to their proportionate exercises of Call Warrants. (iv) If fewer than all tendered Underlying Securities are accepted for payment and paid for, (A) the amount of Call Warrants exercised shall be reduced to an amount that corresponds to a number of Certificates that could be exchanged in an Optional Exchange for the Underlying Securities accepted for payment and paid for (without regard to any restrictions on the amount to be exchanged, so long as such restrictions would have been satisfied had all tendered Underlying Securities been accepted for payment and paid for); (B) each Warrant Holder's exercise shall be reduced by its share (proportionate to the amount specified in its exercise notice) of the amount of Underlying Securities not accepted for payment and paid for; (C) the Call Price shall be determined after giving effect to the reduction specified in clause (B); (D) the Call Warrants that relate to the reduction specified in clause (B) shall remain outstanding; and (E) the excess of the tender offer proceeds over the Call Price shall be allocated in proportion to the amount of Call Warrants deemed exercised as set forth in clause (A) above or, if the Call Price exceeds the tender offer proceeds the amount of such excess shall be paid by the exercising Warrant Holders pro rata in respect to their proportionate exercises of Call Warrants. (v) If the tender offer is terminated by the Underlying Securities Issuer or any other tender offeror without consummation thereof or if all tenders by the Trust of Underlying Securities are otherwise rejected, then (1) the Call Notices will be of no further force and effect, and (2) any Call Warrants relating to such Call Notices will not be exercised and will remain outstanding. (h) (i) If the Trustee receives notice of a redemption by the Underlying Securities Issuer for some or all of the Underlying Securities, the Trustee shall, within three Business Days, notify the Warrant Agent and forward to the Warrant Agent copies of all materials received by the Trustee in connection therewith. Any Warrant Holder that desires to call Underlying Securities in connection with a redemption by the Underlying Securities Issuer shall send a Call Notice to the Trustee no later than seven Business Days prior to the date such Underlying Securities are to be redeemed. 18 (ii) The Call Date and Optional Exchange Date for any exercise of Call Warrants in connection with a redemption by the Underlying Securities Issuer shall be deemed to be the Business Day on which such Underlying Securities are redeemed by the Underlying Securities Issuer. (iii) The Call Price shall be deducted from the redemption proceeds and paid to the holders of the Class A-1 Certificates and Class A-2 Certificates pro rata in accordance with the provisions of Section 7(d)(v), and the excess of the redemption proceeds over the Call Price shall be paid to the exercising Warrant Holders pro rata in respect to their proportionate exercises of Call Warrants. (iv) If fewer than all Underlying Securities are redeemed by the Underlying Securities Issuer and the amount of Call Warrants exercised corresponds to a number of Class A-1 and Class A-2 Certificates that could be exchanged in an Optional Exchange for a principal amount of Underlying Securities that exceeds the principal amount of Underlying Securities actually redeemed, then, unless otherwise directed by any exercising Warrant Holder, (A) the amount of Call Warrants exercised shall be reduced to an amount that corresponds to a number of Class A-1 and Class A-2 Certificates that could be exchanged in an Optional Exchange for the principal amount of Underlying Securities redeemed by the Underlying Securities Issuer (without regard to any restrictions on the amount to be exchanged); (B) each Warrant Holder's exercise shall be reduced by its share (proportionate to the amount specified in its exercise notice) of the amount of such excess; (C) the Call Price shall be determined after giving effect to the reduction specified in clause (B); (D) the Call Warrants that relate to the reduction specified in clause (B) shall remain outstanding; and (E) the excess of the redemption proceeds over the Call Price shall be allocated in proportion to the amount of Call Warrants deemed exercised as set forth in clause (A) above. (v) If the Underlying Securities are not redeemed by the Underlying Securities Issuer for any reason, then (1) the Call Notices will be of no further force and effect, and (2) any Call Warrants relating to such Call Notices will not be exercised and will remain outstanding. Section 8. Notices of Events of Default. As promptly as practicable after, and in any event within 30 days after, the occurrence of any Event of Default actually known to the Trustee, the Trustee shall give notice of such Event of Default to the Depository, or, if any Certificates are not then held by DTC or any other depository, directly to the registered holders of such Certificates, and to the Warrant Agent. However, except in the case of an Event of Default relating to the payment of principal of or interest on any of the Underlying Securities, the Trustee will be protected in withholding such notice if in good faith it determines that the withholding of such notice is in the interest of the Certificateholders. 19 Section 9. Miscellaneous. (a) The provisions of Section 4.04, Advances, of the Standard Terms shall not apply to the Boeing Note-Backed Series 2003-7 Certificates. (b) The provisions of Section 4.07, Optional Exchange, of the Standard Terms shall not apply to the Boeing Note-Backed Series 2003-7 Certificates. (c) The Trustee shall simultaneously forward reports to Certificateholders pursuant to Section 4.03 of the Standard Terms and to the New York Stock Exchange. (d) Except as expressly provided herein, the Certificateholders shall not be entitled to terminate the Trust or cause the sale or other disposition of the Underlying Securities. (e) The provisions of Section 3.07(d) of the Standard Terms shall not apply to the Boeing Note-Backed Series 2003-7 Certificates. (f) If the Trustee has not received payment with respect to a Collection Period on the Underlying Securities on or prior to the related Distribution Date, such distribution will be made promptly upon receipt of such payment. No additional amounts shall accrue on the Certificates or be owed to Certificateholders as a result of such delay; provided, however, that any additional interest owed and paid by the Underlying Securities Issuer as a result of such delay shall be paid to the Class A-1 Certificateholders and Class A-2 Certificateholders pro rata in proportion to their respective entitlements to such delayed payments. (g) The outstanding principal balance of the Certificates shall not be reduced by the amount of any Realized Losses (as defined in the Standard Terms). (h) The Trust may not engage in any business or activities other than in connection with, or relating to, the holding, protecting and preserving of the Trust Property and the issuance of the Certificates and the Call Warrants, and other than those required or authorized by the Trust Agreement or incidental and necessary to accomplish such activities. The Trust may not issue or sell any certificates or other obligations other than the Certificates and the Call Warrants or otherwise incur, assume or guarantee any indebtedness for money borrowed. Notwithstanding Section 3.05 of the Standard Terms, funds on deposit in the Certificate Account shall not be invested. Section 2.01(f) of the Standard Terms shall be superseded by this provision. (i) Notwithstanding anything in the Trust Agreement to the contrary, the Trustee may be removed upon 60 days prior written notice delivered by the holders of Class A-1 Certificates and Class A-2 Certificates representing the Required Percentage--Removal. (j) In the event that the Internal Revenue Service challenges the characterization of the Trust as a grantor trust, the Trustee shall then file such forms as the Depositor may specify to establish the Trust's election pursuant to Section 761 of the Code to exclude the Trust from the application of Subchapter K of the Code and is hereby empowered to execute such forms on behalf of the Certificateholders. 20 (k) Notwithstanding anything in the Standard Terms to the contrary, the Trustee, upon written direction by the Depositor, will execute the Certificates. (l) In relation to Section 7.01(f) of the Standard Terms, any periodic reports filed by the Trustee pursuant to the Exchange Act in accordance with the customary practices of the Depositor, need not contain any independent reports. (m) Notwithstanding anything in the Trust Agreement to the contrary, the Trustee will have no recourse to the Underlying Securities. (n) A Plan fiduciary, whether or not a Certificateholder at such time, may request in writing that the Trustee provide such Plan fiduciary with such information as shall be necessary for it to determine whether any of the Call Warrant holders is (i) a "party in interest" (within the meaning of ERISA, Section 3(14)); or (ii) a "disqualified person" within the meaning of Internal Revenue Code ("Code") Section 4975(e)(2) with respect to any employee benefit plan or Plan identified to the Trustee by such Plan fiduciary at the time such request is made in order for the Plan fiduciary to determine whether an investment in the Certificates by such Plan is or would be permissible under ERISA or the Code. Any such written request of a Plan fiduciary shall be accompanied by a certification of the Plan fiduciary, opinion of counsel experienced in such issues, and such other documentation as the Trustee may require, in order to establish that such disclosure is necessary for the Plan fiduciary to determine compliance with ERISA and the Code, as well as a confidentiality agreement, whereby the Plan fiduciary agrees not to disclose the identity of any Call Warrant holders except to any legal or other experts as necessary to make such determination. The holder of a Call Warrant shall upon reasonable request of the Trustee, in order for the Trustee to satisfy its obligations to a Plan fiduciary, provide the Trustee with any one or more of the following, in the sole discretion of the Call Warrant holder: (i) a certificate that each of the Call Warrant holders is not (x) a "party in interest" (within the meaning of ERISA, Section 3(14)) with respect to any "employee benefit plan" as defined in ERISA, Section 3(3); or (y) a "disqualified person" within the meaning of Internal Revenue Code Section 4975(e)(2) with respect to a "Plan" as defined in Code Section 4975(e)(1) except in each case with respect to plans sponsored by the Call Warrant holder or its affiliates which cover employees of the Call Warrant holder and/or such affiliates; (ii) a certificate that each of the Call Warrant holders is not such a "party in interest" or "disqualified person" with respect to any employee benefit plan or Plan identified to the Trustee by such Plan fiduciary at the time such request is made; or (iii) a written consent to the limited disclosure of the respective Call Warrant holder's identity to a specific Plan fiduciary solely for purposes of allowing the Trustee to satisfy its obligations to a Plan fiduciary. (o) The Trust will not merge or consolidate with any other entity without confirmation from each Rating Agency that such merger or consolidation will not result in the qualification, reduction or withdrawal of its then-current rating on the Certificates. (p) All directions, demands and notices hereunder or under the Standard Terms shall be in writing and shall be delivered as set forth below (unless written notice is otherwise provided to the Trustee). 21 If to the Depositor, to: Lehman ABS Corporation 745 Seventh Avenue New York, New York 10019 Attention: Structured Credit Trading Telephone: (212) 526-6575 Facsimile: (201) 508-4621 If to the Trustee or the Warrant Agent, to: U.S. Bank Trust National Association 100 Wall Street New York, New York 10005 Attention: Corporate Trust Telephone: (646) 835-5500 Facsimile: (212) 809-5459 If to the Rating Agencies, to: Moody's Investors Service, Inc. 99 Church Street New York, New York 10007 Attention: CBO/CLO Monitoring Department Telephone: (212) 553-1494 Facsimile: (212) 553-0355 and to: Standard & Poor's Ratings Services 55 Water Street New York, New York 10041 Attention: Structured Finance Surveillance Group Telephone: (212) 438-2482 Facsimile: (212) 438-2664 If to the New York Stock Exchange, to: New York Stock Exchange, Inc. 20 Broad Street New York, New York 10005 Attention: Robin L.

Governing Law. THIS SERIES SUPPLEMENT AND THE TRANSACTIONS DESCRIBED HEREIN SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO THE CHOICE OF LAWS PROVISIONS THEREOF. Section 11. Counterparts. This Series Supplement may be executed in any number of counterparts, each of which shall be deemed to be an original, and all such counterparts shall constitute but one and the same instrument. Section 12. Termination of the Trust. The Trust shall terminate upon the earliest to occur of (i) the payment in full at maturity or sale by the Trust after a payment default or an acceleration or other early payment of the Underlying Securities and the distribution in full of all amounts due to the Class A-1 Certificateholders and Class A-2 Certificateholders; (ii) the exercise of all outstanding Call Warrants by the Warrant Holder; (iii) the Final Scheduled Distribution Date and (iv) the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the United States to the Court of St. James, living on the date hereof. Section 13. Sale of Underlying Securities; Optional Exchange. In the event of a sale of the Underlying Securities pursuant to Section 5(e) hereof or pursuant to the instructions of the Warrant Agent under Section 1.2 of the Warrant Agent Agreement, the Trustee shall solicit bids for the sale of the Underlying Securities with settlement thereof on or before the third (3rd) Business Day after such sale from three leading dealers in the relevant market. Any of the following dealers (or their successors) shall be deemed to qualify as leading dealers: (1) Credit Suisse First Boston Corporation, (2) Goldman, Sachs & Co., (3) Merrill Lynch, Pierce, Fenner & Smith Incorporated, (4) UBS Warburg LLC, (5) Salomon Smith Barney Inc., and (6) except in the case of a sale related to the exercise of Call Warrants by the Depositor or any Affiliate thereof, Lehman Brothers Inc. The Trustee shall not be responsible for the failure to obtain a bid so long as it has made reasonable efforts to obtain bids. If a bid for the sale of the Underlying Securities has been accepted by the Trustee but the sale has failed to settle on the proposed settlement date, the Trustee shall request new bids from such leading dealers. In the event of an Optional Exchange, the Trustee shall only deliver the Underlying Securities to the purchaser of 23 such Underlying Securities or sell the Underlying Securities pursuant to this Section 13, as the case may be, against payment in same day funds deposited into the Certificate Account. Section 14. Amendments. Notwithstanding anything in the Trust Agreement to the contrary, in addition to the other restrictions on modification and amendment contained therein, the Trustee shall not enter into any amendment or modification of the Trust Agreement which would adversely affect in any material respect the interests of the holders of any class of Certificates without the consent of the holders of 100% of such class of Certificates; provided, however, that no such amendment or modification will be permitted which would cause the Trust to be taxed as an association or publicly traded partnership taxable as a corporation for federal income tax purposes. Unless otherwise agreed, the Trustee shall provide five Business Days written notice to each Rating Agency before entering into any amendment or modification of the Trust Agreement pursuant to this Section 14. Section 15. Voting of Underlying Securities, Modification of Indenture. (a) The Trustee, as holder of the Underlying Securities, has the right to vote and give consents and waivers in respect of the Underlying Securities as permitted by the Depository and except as otherwise limited by the Trust Agreement. In the event that the Trustee receives a request from the Depository, the Underlying Securities Trustee or the Underlying Securities Issuer for its consent to any amendment, modification or waiver of the Underlying Securities, the Indenture or any other document thereunder or relating thereto, or receives any other solicitation for any action with respect to the Underlying Securities, the Trustee shall mail a notice of such proposed amendment, modification, waiver or solicitation to each Certificateholder of record as of such date. The Trustee shall request instructions from the Certificateholders as to whether or not to consent to or vote to accept such amendment, modification, waiver or solicitation. The Trustee shall consent or vote, or refrain from consenting or voting, in the same proportion (based on the relative outstanding Certificate Principal Balances of the Class A-1 Certificates) as the Certificates of the Trust were actually voted or not voted by the Certificateholders thereof as of a date determined by the Trustee prior to the date on which such consent or vote is required; provided, however, that, notwithstanding anything in the Trust Agreement to the contrary, the Trustee shall at no time vote on or consent to any matter (i) unless such vote or consent would not (based on an opinion of counsel) cause the Trust to be taxed as an association or publicly traded partnership taxable as a corporation under the Code, (ii) which would alter the timing or amount of any payment on the Underlying Securities, including, without limitation, any demand to accelerate the Underlying Securities, except in the event of a default under the Underlying Securities or an event which with the passage of time would become an event of default under the Underlying Securities and with the unanimous consent of holders of all outstanding Class A-1 Certificates, Class A-2 Certificates and all Warrant Holders, or (iii) which would result in the exchange or substitution of any of the outstanding Underlying Securities pursuant to a plan for the refunding or refinancing of such Underlying Securities except in the event of a default under the Indenture and only with the consent of Certificateholders representing 100% of the Class A-1 Certificates, 100% of the Class A-2 Certificates and 100% of the Warrant Holders. The Trustee shall have no liability for any failure to act resulting from Certificateholders' late return of, or failure to return, directions requested by the Trustee from the Certificateholders. 24 (b) In the event that an offer is made by the Underlying Securities Issuer to issue new obligations in exchange and substitution for any of the Underlying Securities, pursuant to a plan for the refunding or refinancing of the outstanding Underlying Securities or any other offer is made for the Underlying Securities, the Trustee shall notify the Class A-1 Certificateholders, Class A-2 Certificateholders and the Warrant Holders of such offer promptly. Subject to the rights of the Warrant Holders to exercise Call Warrants in connection with a tender offer for the Underlying Securities, the Trustee must reject any such offer unless an Underlying Securities event of default has occurred and the Trustee is directed by the affirmative vote of the holders of 100% of the Class A-1 Certificates, Class A-2 Certificates and Call Warrants to accept such offer and the Trustee has received the tax opinion described above. If pursuant to the preceding sentence, the Trustee accepts any such offer the Trustee shall promptly notify the Rating Agencies. (c) If an event of default under the Indenture occurs and is continuing, and if directed by a majority of the outstanding Class A-1 Certificateholders and Class A-2 Certificateholders, the Trustee shall vote the Underlying Securities in favor of directing, or take such other action as may be appropriate to direct, the Underlying Securities Trustee to declare the unpaid principal amount of the Underlying Securities and any accrued and unpaid interest thereon to be due and payable. Section 16. Additional Depositor Representation. It is the express intent of the parties hereto that the conveyance of the Underlying Securities by the Depositor to the Trustee be, and be construed as, a sale of the Underlying Securities by the Depositor and not a pledge of any Underlying Securities by the Depositor to secure a debt or other obligation of the Depositor. In the event that, notwithstanding the aforementioned intent of the parties, any Underlying Securities are held to be property of the Depositor, then, it is the express intent of the parties that such conveyance be deemed a pledge of such Underlying Securities and all proceeds thereof by the Depositor to the Trustee to secure a debt or other obligation of the Depositor, pursuant to Section 10.07 of the Standard Terms. In connection with any such grant of a security interest in the Underlying Securities and all proceeds thereof (including any such grant in connection with any sale of additional Underlying Securities pursuant to Section 3(d)), the Depositor hereby represents and warrants to Trustee as follows: (i) In the event the Underlying Securities are held to be property of the Depositor, then the Trust Agreement creates a valid and continuing security interest (as defined in the Uniform Commercial Code as in effect in the applicable jurisdiction (the "UCC")) in the Underlying Securities in favor of the Trustee which security interest is prior to all other liens, and is enforceable as such as against creditors of, and purchasers from, the Depositor. (ii) The Underlying Securities have been credited to a trust account (the "Securities Account") established in the name of the Trustee in accordance with Section 2.01 of the Standard Terms. U.S. Bank Trust National Association, as securities intermediary (the "Securities Intermediary") has established the Securities Account and has agreed to treat the Underlying Securities as "financial assets" within the meaning of the UCC. 25 (iii) Immediately prior to the transfer of the Underlying Securities to the Trust, the Depositor owned and had good and marketable title to the Underlying Securities free and clear of any lien, claim or encumbrance of any Person. (iv) The Depositor has received all consents and approvals required by the terms of the Underlying Securities to the transfer to the Trustee all of its interest and rights in the Underlying Securities as contemplated by the Trust Agreement. (v) The Depositor has taken all steps necessary to cause the Securities Intermediary to identify on its records that the Trustee is the Person owning the security entitlements credited to the Securities Account. (vi) Other than the security interest granted to the Trust pursuant to this Agreement, the Depositor has not assigned, pledged, sold, granted a security interest in or otherwise conveyed any interest in the Underlying Securities (or, if any such interest has been assigned, pledged or otherwise encumbered, it has been released). The Depositor has not authorized the filing of and is not aware of any financing statements against the Depositor that includes a description of the Underlying Securities other than any financing statement relating to the security interest granted to the Trust hereunder. The Depositor is not aware of any judgment or tax lien filings against the Depositor. (vii) The Securities Account is not in the name of any Person other than the Trustee. The Depositor has not consented to the compliance by the Securities Intermediary, with entitlement orders of any Person other than the Trustee. 26 IN WITNESS WHEREOF, the parties hereto have caused this Series Supplement to be duly executed by their respective authorized officers as of the date first written above.

W I T N E S S E T H: WHEREAS, the Depositor created Corporate Backed Trust Certificates, Boeing Note-Backed Series 2003-7 Trust (the "Trust"), a trust created under the laws of the State of New York pursuant to a Standard Terms for Trust Agreements, dated as of January 16, 2001 (the "Agreement"), between Lehman ABS Corporation (the "Depositor") and U.S. Bank Trust National Association, a national banking association, not in its individual capacity but solely as Trustee (the "Trustee"), as supplemented by the Series Supplement 2003-7, dated as of March 21, 2003 (the "Series Supplement" and, together with the Agreement, the "Trust Agreement"), between the Depositor and the Trustee; and WHEREAS, in connection with the creation of the Trust and the deposit therein of the Underlying Securities, it is desired to provide for the issuance of trust certificates (the "Certificates") evidencing undivided interests in the Trust and call warrants with respect to the Certificates ("Call Warrants"). NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants expressed herein, it is hereby agreed by and between the Depositor, the Warrant Agent and the Trustee that except as otherwise specified herein or as the context may otherwise require, capitalized terms used herein but not defined herein shall have the respective meanings set forth below in the Series Supplement, and as follows: ARTICLE I EXERCISE OF CALL WARRANTS Section 1.1 Manner of Exercise. (a) Call Warrants may be exercised by any holder thereof (each, a "Warrant Holder") in whole or in part on any Call Date. The following conditions shall apply to any exercise of Call Warrants: (i) A notice (each, a "Call Notice") specifying the number of Call Warrants being exercised and the Call Date shall be delivered to the Warrant Agent and the Trustee at least 5 Business Days before such Call Date. B-1 (ii) The Warrant Holder shall surrender the Call Warrants to the Warrant Agent at its office specified in Section 6.3 hereof no later than 10:00 a.m. (New York City time) on such Call Date. (iii) The Warrant Holder shall have made payment to the Warrant Agent, by wire transfer or other immediately available funds acceptable to the Warrant Agent, in the amount of the Call Price, no later than 10:00 a.m. (New York City time) on the Call Date. (iv) The Warrant Holder shall exercise Call Warrants relating to Class A-1 Certificates, Call Warrants relating to the Class A-2 Certificates which represent a like percentage of all Class A-1 Certificates and Class A-2 Certificates, respectively. (v) The Warrant Holder may not exercise the Call Warrants at any time when such Warrant Holder is insolvent, and such Warrant Holder shall be required to certify that it is solvent at the time of exercise, by completing the Form of Subscription attached to the Call Warrants and delivering such completed Form of Subscription to the Trustee on or prior to the Call Date and by delivering to the Trustee a form reasonably satisfactory to the Trustee of the solvency certificate required pursuant to Section 7(d)(ii) of the Series Supplement. (vi) The Warrant Holder shall have satisfied any other conditions to the exercise of Call Warrants set forth in Section 7(d) of the Series Supplement. (b) Upon exercise of Call Warrants, any Warrant Holder other than the Depositor or any Affiliate of the Depositor shall be entitled to delivery by the Trustee of the Called Certificates. The "Called Certificates" shall be, in the case of the Class A-1 Certificates, Class A-1 Certificates having a Certificate Principal Amount equal to $25 per Call Warrant, and in the case of the Class A-2 Certificates, Class A-2 Certificates having a notional balance equal to $100,000 per Call Warrant. Unless otherwise specified therein, such Call Notice shall be deemed to be notice of an Optional Exchange pursuant to Section 7(b) of the Series Supplement. Any Warrant Holder which is the Depositor or any Affiliate of the Depositor shall receive the proceeds of the sale of the Called Underlying Securities and shall not be entitled to receive the related Called Certificates or Called Underlying Securities. "Called Underlying Securities" are Underlying Securities which represent the same percentage of the Underlying Securities as the Called Certificates represent of the Class A-1 Certificates and the Class A-2 Certificates. (c) The Warrant Agent shall notify the Trustee immediately upon its receipt of a Call Notice and upon receipt of payment of the Call Price. The Warrant Agent shall transfer the amount of any paid Call Price to the Trustee in immediately available funds, for deposit in the Certificate Account and application pursuant to the Trust Agreement on the applicable Call Date (and, pending such transfer, shall hold such amount for the benefit of the Warrant Holder in a segregated trust account). B-2 (d) Delivery of a Call Notice does not give rise to an obligation on the part of the Warrant Holder to pay the Call Price. If, by 10:00 a.m. (New York City time) on the Call Date, the Warrant Holder has not paid the Call Price, except in connection with a Call Notice relating to a tender offer for or redemption of Underlying Securities, then the Call Notice shall automatically expire and none of the Warrant Holder, the Warrant Agent or the Trustee shall have any obligation with respect to the Call Notice. The expiration of a Call Notice shall in no way affect the Warrant Holder's right to deliver a Call Notice at a later date. The Call Price for a call in connection with a tender offer or redemption shall be deducted from the proceeds of a tender offer or a redemption by the Trust pursuant to Section 7(g)(iii) or Section 7(h)(iii), as applicable, of the Series Supplement. Section 1.2 Transfer of Certificates. As soon as practicable after each surrender of Call Warrants in whole or in part on the Call Date and upon satisfaction of all other requirements described in the Call Warrants and in Section 1.1 hereof, the Warrant Agent shall instruct the Trustee as follows: (a) if Call Warrants are being exercised by any Warrant Holder other than the Depositor or any Affiliate of the Depositor, to cause the Called Certificates to reflect the Warrant Holder's beneficial ownership of such Certificates and if such Call Notice is also deemed to be a notice of Optional Exchange, to cause a distribution of Underlying Securities to the Warrant Holder in accordance with Section 7(a) of the Series Supplement, provided, however, that if such a Call Notice and Optional Exchange is in connection with a tender offer or a redemption, the Warrant Agent shall instruct the Trustee to distribute to the exercising Warrant Holder the excess of the tender offer or redemption proceeds over the Call Price pursuant to Section 7(g)(iii) or Section 7(h)(iii), as applicable, of the Series Supplement, or (b) if the Call Warrants are being exercised by the Depositor or any Affiliate of the Depositor, to cause the Called Underlying Securities to be sold pursuant to Section 13 of the Series Supplement and to distribute the proceeds of such sale to the Warrant Holder. If such exercise is in part only, the Warrant Agent shall instruct the Trustee to authenticate new Call Warrants of like tenor, representing the outstanding Call Warrants of the Warrant Holder and the Warrant Agent shall deliver such Call Warrants to the Warrant Holder. In each case, the Trustee shall act in accordance with such instructions. Section 1.3 Cancellation and Destruction of Call Warrants. All Call Warrants surrendered to the Warrant Agent for the purpose of exercise (in whole or in part) pursuant to Section 1.1 and actually exercised, or for the purpose of transfer or exchange pursuant to Article III, shall be cancelled by the Warrant Agent, and no Call Warrant (other than that reflecting any such transfer or exchange) shall be issued in lieu thereof. The Warrant Agent shall destroy all cancelled Call Warrants. B-3 Section 1.4 No Rights as Holder of Certificates Conferred by Call Warrants.
