(a) The FTPS Unit Servicing Agent shall perform all of the duties with respect to recordkeeping of FTPS Units and FTPS Unit holders, distributions, redemption of FTPS Units and communications to and with FTPS Unit holders listed below. (1) The FTPS Unit Servicing Agent shall keep proper books of record and account of all of the transactions in the FTPS Units of each Trust under this Indenture at its corporate office, including a record of the name and address of, and the FTPS Units issued by each Trust and held by, every FTPS Unit holder, and such books and records of each Trust shall be made available to the Trustee and the Depositor promptly upon request and open to inspection by any FTPS Unit holder of such Trust, with respect to such FTPS Unit holders transactions, at all reasonable times during usual business hours. Without limiting the foregoing, the FTPS Unit Servicing Agent shall make any records or documents described in Reg. 270.31(a)-1 under the Investment Company Act of 1940 available promptly to the Trustee and the Depositor upon request during usual business hours and will preserve such records and documents for the periods prescribed in Reg. 270.31(a)-2 thereunder.

(3) In connection with such distributions set forth above, the FTPS Unit Servicing Agent shall furnish a Distribution Statement to FTPS Unit holders of record on its books. The content and frequency of such Distribution Statements shall in no respect be less detailed or frequent than that specified in Section 3.06 of the Standard Terms and Conditions of Trust. (4) The FTPS Unit Servicing Agent shall transmit to each FTPS Unit holder of record any notice or other communication received from the Trustee and shall be solely responsible for soliciting and transmitting to the Trustee any notice required from FTPS Unit holders. (5) For purposes of permitting FTPS Unit holders to satisfy any reporting requirements of applicable federal or state tax law, the FTPS Unit Servicing Agent shall provide the Trustee with the name, address, number of FTPS Units held by, and such other information as requested by the Trustee, for every FTPS Unit holder so that the Trustee can transmit to any FTPS Unit holder of record on the FTPS Unit Servicing Agents books any reports required to be distributed pursuant to Section 4.02 of the Standard Terms and Conditions of Trust. The Trustee may rely on the accuracy and completeness of the information (including any records or documents made available) provided to it by the FTPS Unit Servicing Agent and may accept such information without inquiry. Each of the Depositor and the FTPS Unit Servicing Agent hereby agree, jointly and severally, to indemnify the Trustee and hold Trustee harmless from and against any and all costs, expenses, penalties, damages, liabilities or claims including attorneys' and accountants' fees sustained or incurred by or asserted against the Trustee by reason of or as a result of any of the information provided to the Trustee by the FTPS Unit Servicing Agent being inaccurate or incomplete. This indemnity shall be a continuing obligation of each of the Depositor and the FTPS Unit Servicing Agent, and their successors and assigns, notwithstanding the termination of this Trust Agreement. (6) The FTPS Unit Servicing Agent shall distribute to redeeming FTPS Unit holders of record on its books redemption proceeds it receives pursuant to Section 5.02 of the Standard Terms and Conditions of Trust from the Trustee as the sole record owner of FTPS Units on the Trustees books.

The content of such Final Distribution Statements shall in no respect be less detailed than that specified in Section 8.02 of the Standard Terms and Conditions of Trust. (9) As requested by the Depositor and/or the Trustee, the FTPS Unit Servicing Agent shall perform such other functions which, from time to time, are agreed upon by the parties hereto and which may give rise to additional fees. (b) As compensation for providing the services set forth herein, of a character described in Section 26(a)(2)(C) of the Investment Company Act of 1940, and to the extent that such services are in addition to, and do not duplicate, the services to be performed by the Trustee, FTP Services LLC shall receive, in arrears, against a statement or statements therefore submitted to the Trustee monthly or annually an aggregate annual fee in the per Unit amount set forth in Part II of the Trust Agreement for the Trust, calculated based on the largest number of Units outstanding during the calendar year, except during the initial offering period as determined in Section 4.01 of the Standard Terms and Conditions of Trust, in which case the fee is calculated based on the largest number of Units outstanding during the period for which the compensation is paid (such annual fee to be pro rated for any calendar year in which FTP Services LLC provides services described herein during less than the whole of such year). Such fee may exceed the actual cost of providing such services for the Trust, but at no time will the total amount received by FTP Services LLC for rendering the services described in this Section 3.16 and First Trust Advisors, L.P. for rendering the services described in Section 4.03 to unit investment trusts of which the Depositor is the sponsor in any calendar year exceed the aggregate cost to FTP Services LLC and First Trust Advisors, L.P. of supplying such services in such year. Such compensation may, from time to time, be adjusted by the Depositor provided that the total adjustment upward does not, at the time of such adjustment, exceed the percentage of the total increase, after the date hereof, in consumer prices for services as measured by the United States Department of Labor Consumer Price Index entitled "All Services Less Rent of Shelter" or similar index, if such index should no longer be published. The consent or concurrence of any Unit holder hereunder shall not be required for any such adjustment or increase. Such compensation shall be paid by the Trustee, upon receipt of an invoice therefore from FTP Services LLC, which shall constitute the representation by FTP Services LLC that the bookkeeping and administrative services for which compensation is claimed are properly compensable hereunder and that the aggregate cost incurred by FTP Services LLC of providing FTPS Unit shareholder servicing hereunder was not less than the compensation claimed, upon which representation the Trustee may conclusively rely. Such compensation shall be charged against the Income and/or Capital Accounts, in accordance with Section 3.05 of the Standard Terms and Conditions of Trust. If the cash balance in the Income and Capital Accounts shall be insufficient to provide for amounts payable pursuant to this Section 3.16, the Trustee shall have the power to sell (i) Securities from the current list of Securities designated to be sold pursuant to Section 5.02 hereof, or (ii) if no such Securities have been so designated, such Securities as the Trustee may see fit to sell in its own discretion, and to apply the proceeds of any such sale in payment of the amounts payable pursuant to this Section 3.16. All moneys payable to the FTPS Unit Servicing Agent pursuant to this Section 3.16 shall be secured by a lien on the Trust prior to the interest of Unit holders, but no such lien shall be prior to any lien in favor of the Trustee under the provisions of Section 6.04 of the Standard Terms and Conditions of Trust. (c) The FTPS Unit Servicing Agent shall be under no liability for any action taken in good faith on any appraisal, paper, order, list, demand, request, consent, affidavit, notice, opinion, direction, evaluation, endorsement, assignment, resolution, draft or other document, whether or not of the same kind, prima facie properly executed, or for the disposition of moneys, pursuant to this Indenture, except by reason of its own negligence, lack of good faith or willful misconduct, provided that the FTPS Unit Servicing Agent shall not in any event be liable or responsible for any evaluation made by the Evaluator. (d) Except as the context otherwise requires, the FTPS Unit Servicing Agent shall be subject to the provisions of Section 4.05 herein in the same manner as it would if it were the Evaluator. (e) The FTPS Unit Servicing Agent shall be indemnified ratably by the affected Trust and held harmless against any loss or liability accruing to it without negligence, bad faith or willful misconduct on its part, arising out of or in connection with the operations of the Trust, including the costs and expenses (including counsel fees) of defending itself against any claim of liability in the premises, including without limitation any loss, liability or expense incurred in acting pursuant to written directions to the FTPS Unit Servicing Agent given by the Trustee or Depositor from time to time in accordance with the provisions of this Indenture or in undertaking actions from time to time which the FTPS Unit Servicing Agent deems necessary in its discretion to protect the Trust and the rights and interests of the FTPS Unit holders pursuant to the terms of this Indenture. (f) The FTPS Unit Servicing Agent shall conduct its operations in a manner that is compatible with the current operational procedures and requirements of the Trustee (including, without limiting the foregoing, the provision and receipt of data in such format and meeting such technical requirements as the Trustee may specify) and shall exercise its best efforts to accommodate any changes in the operational procedures and requirements which the Trustee may make upon prior notice to the FTPS Unit Servicing Agent. The Depositor acknowledges and agrees that the default of the FTPS Unit Servicing Agent in its obligations under this paragraph, or the performance by the FTPS Unit Servicing Agent of its obligations in a manner which shall adversely affect the Trustees performance of its duties, shall be a sufficient grounds for the Trustee to remove the FTPS Unit Servicing Agent pursuant to Section 3.16(d) and Section 4.05. (g) As used in this Section 3.16, "FTPS Unit holder," when referring to the records of the Trustee, shall mean the FTPS Unit Servicing Agent and, when referring to the records to be maintained by the FTPS Unit Servicing Agent, shall mean each owner of a FTPS Unit identified on the records of the FTPS Unit Servicing Agent." J. Section 4.01(a) and (b) of the Standard Terms and Conditions of Trust shall be amended to include the FTPS Unit Servicing Agent among the parties who are furnished information concerning the Evaluation of each issue of Securities deposited in the Trust and the Trust Fund Evaluation. K. The second sentence of the first paragraph of Section 4.03 shall be replaced with the following: Such fee may exceed the actual cost of providing such services for the Trust, but at no time will the total amount received by First Trust Advisors, L.P. for rendering the services described in this Section 4.03 and FTP Services LLC for rendering the services described in Section 3.16 to unit investment trusts of which the Depositor is the sponsor in any calendar year exceed the aggregate cost to FTP Services LLC and First Trust Advisors, L.P. of supplying such services in such year. L. Section 4.04 of the Standard Terms and Conditions of Trust shall be replaced in its entirety by the following: "Section 4.04. Liability of Evaluator. The Trustee, FTPS Unit Servicing Agent, Depositor and the Unit holders may rely on any Evaluation furnished by First Trust Advisors, L.P., acting in its capacity as Evaluator, and shall have no responsibility for the accuracy thereof. The determinations made by the Evaluator hereunder shall be made in good faith upon the basis of the best information available to it. The Evaluator shall be under no liability to the Trustee, FTPS Unit Servicing Agent, Depositor or the Unit holders for errors in judgment; provided, however, that this provision shall not protect the Evaluator against any liability to which it would otherwise be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties hereunder." M. The second sentence of the first paragraph of Section 5.01 shall be amended to delete subsection (ii) of such sentence and replace it in its entirety with the following: "(ii) amounts representing estimated accrued expenses of such Trust including but not limited to unpaid fees and expenses of the Trustee, the Evaluator, the Portfolio Supervisor, the FTPS Unit Servicing Agent, the Depositor and its counsel, in each case as reported by the Trustee to the Depositor on or prior to the date of Evaluation," N. Section 6.01(c) of the Standard Terms and Conditions of Trust shall be replaced in its entirety with the following: "(c) The Trustee shall not be responsible for or in respect of the recitals herein, the validity or sufficiency of this Indenture or for the due execution hereof by the Depositor, the Portfolio Supervisor, the Evaluator, or the FTPS Unit Servicing Agent, or for the form, character, genuineness, sufficiency, value or validity of any of the Securities (except that the Trustee shall be responsible for the exercise of due care in determining the genuineness of Securities delivered to it pursuant to contracts for the purchase of such Securities) or for or in respect of the validity or sufficiency of the Units or of the Certificates (except for the due execution thereof by the Trustee) or for the due execution thereof by the Depositor, and the Trustee shall in no event assume or incur any liability, duty or obligation to any Unit holder, the FTPS Unit Servicing Agent or the Depositor other than as expressly provided for herein. The Trustee shall not be responsible for or in respect of the validity of any signature by or on behalf of the Depositor, the Portfolio Supervisor, the Evaluator or the FTPS Unit Servicing Agent;" O. Section 8.02(b) of the Standard Terms and Conditions of Trust shall be replaced in its entirety with the following: "(b) deduct from the Income Account of such Trust or, to the extent that funds are not available in such Account, from the Capital Account of such Trust, and pay accrued and unpaid fees of the Evaluator, the Portfolio Supervisor, the FTPS Unit Servicing Agent, the Depositor and counsel in connection with such Trust, if any;" P. Section 8.05 of the Standard Terms and Conditions of Trust shall be amended to add the following paragraph immediately preceding the last paragraph of such section: "Any notice, demand, direction or instruction to be given to the FTPS Unit Servicing Agent shall be in writing and shall be duly given if mailed or delivered to the FTPS Unit Servicing Agent at 1001 Warrenville Road, Lisle, Illinois 60532, or at such other address as shall be specified by the FTPS Unit Servicing Agent to the other parties hereto in writing. Q. Notwithstanding anything to the contrary in the Standard Terms and Conditions of Trust, the second paragraph in Section 8.02 shall be amended to read as follows: In the event of any termination of the Trust prior to the Mandatory Termination Date, the Trustee shall proceed to liquidate the Securities then held and make the payments and distributions provided for hereinafter in this Section 8.02, except that in such event, the distribution to each Unit holder shall be made in cash and shall be such Unit holders pro rata interest in the balance of the principal and income accounts after the deductions herein provided. In the event that the Trust shall terminate on or after the Mandatory Termination Date, the Trustee shall, at least thirty days prior to the Mandatory Termination Date, send a written notice to all Unit holders of record. If such Unit holder owns at least the minimum number of Units of Trust set forth in Part II of the Trust Agreement, such notice shall further indicate that such Unit holder may elect to receive an in- kind distribution of their pro rata share of the Securities, to the extent of whole shares. The Trustee will honor duly executed requests for in-kind distributions received (accompanied by the electing Unit holders Certificate, if issued) by the close of business ten business days prior to the Mandatory Termination Date. Unit holders who do not effectively request an in-kind distribution shall receive their distribution upon termination in cash. Unit holders shall receive their distribution upon termination in cash. R. Section 6.01 shall be amended to add the following as paragraph (n): "(n) The Trustee may act, and may engage any corporation, partnership or other entity affiliated with The Bank of New York (an "Affiliated Entity") to act, as broker or dealer to execute transactions, including the purchase or sale of any securities currently distributed, underwritten or issued by any Affiliated Entity, and receive, or pay to the Affiliated Entity, as applicable, compensation for such services at standard commission rates, markups or concessions." S. Section 3.02 shall be amended to read in its entirety as follows: Section 3.02 Income Account. The Trustee shall collect the dividends and other cash distributions on the Securities in each Trust which would be treated as dividend (other than capital gain dividends) or interest income under the Internal Revenue Code as such become payable (including all monies which would be so treated representing penalties for the failure to make timely payments on the Securities, or as liquidated damages for default or breach of any condition or term of the Securities or of the underlying instrument relating to any Securities and other income attributable to a Failed Contract Obligation for which no Replacement Security has been obtained pursuant to Section 3.12 hereof) and credit such income to a separate account for each Trust to be known as the "Income Account." Any non-cash distributions received by a Trust shall be sold to the extent they would be treated as dividend or interest income under the Internal Revenue Code and the proceeds shall be credited to the Income Account. Except as provided in the preceding sentence, non-cash distributions received by a Trust (other than a non-taxable distribution of the shares of the distributing corporation which shall be retained by a Trust) shall be dealt with in the manner described in Section 3.11, herein, and shall be retained or disposed of by such Trust according to those provisions and the proceeds thereof shall be credited to the Capital (Principal) Account. Neither the Trustee nor the Depositor shall be liable or responsible in any way for depreciation or loss incurred by reason of any such sale. All other distributions received by a Trust shall be credited to the Capital (Principal) Account. T. Notwithstanding anything to the contrary in the Standard Terms and Conditions of Trust, the first paragraph of Section 3.05.(II)(a) shall be amended to provide as follows: On each Distribution Date, the Trustee shall distribute to each Unit holder of record at the close of business on the Record Date immediately preceding such Distribution Date an amount per Unit equal to such Unit holder's Income Distribution (as defined below), plus such Unit holder's pro rata share of the balance of the Capital Account (except for monies on deposit therein required to purchase Contract Obligations and monies constituting proceeds of pro-rata sales of Trust assets to effect redemptions, which proceeds shall be retained for payment of redemptions) computed as of the close of business on such Record Date after deduction of any amounts provided in Subsection I, provided, however, that the Trustee shall not be required to make a distribution from the Capital Account unless the balance available for distribution is equal to or greater than $1.00 per 100 Units, except that, notwithstanding any provision of the Standard Terms and Conditions of Trust or this Trust Agreement to the contrary, the Trustee shall on any Distribution Date distribute the cash available for distribution in the Income and Capital Accounts within the meaning of Treas. Reg. 1.671-5(b)(5) if the aggregate amount of such cash available for distribution is equal to or greater than .1% of the net asset value of the Trust on the related Record Date. This provision is intended to comply with Treas. Reg. 1.671-5(c)(2)(v)(C) and shall be interpreted consistent therewith and with any successor regulations. U. Notwithstanding anything to the contrary in the Standard Terms and Conditions of Trust, the ninth paragraph of Section 5.02 of the Standard Terms shall be amended to read in its entirety as follows: "For the purpose of funding the Principal Account for payment of the Redemption Value with respect to each tender of a Unit or Units for redemption, the Depositor may direct the trustee to sell and, in the absence of contrary direction from the Depositor, the Trustee may sell, the pro rata amount of each Security allocable to the tendered Units as soon as reasonably practicable following such tender. In determining such pro rata amount, the Trustee may apply the calendar month aggregation method provided in Treas. Reg. 1.671- 5(c)(2)(iv)(G)(3)(i). If the proceeds of such pro rata sales are insufficient, the Trustee may (i) sell additional Securities as directed by the Sponsor or, in the absence of direction, sell Securities in amounts which are reasonably pro rata as determined by the Trustee or (ii) advance funds required to pay the Redemption Value, provided that the Trustee shall have no obligation to advance funds if the unreimbursed amount advanced to the Trust for this purpose then equals at least $15,000. When directed by the Depositor or determined by the Trustee, but in all events as promptly as reasonably practicable whenever the unreimbursed amount advanced by the Trustee equals or exceeds $15,000, the Trustee shall sell additional Securities in the manner provided in clause (i) of the preceding sentence and shall reimburse itself the amount of the advance, provided that the Trustee's right to reimbursement shall not be affected by any delay in sale or reimbursement. The Trustee's right to reimbursement shall be secured by a lien on the Trust prior to the interest of the Unit holders. The net proceeds of any sale of Securities representing income shall be credited to the Income Account and then disbursed therefrom for payment of expenses and payments to Unit holders as otherwise provided in this Indenture. The balance of such net proceeds shall be credited to the Principal Account. The Depositor and the Trustee shall use their reasonable efforts to conduct pro rata sales of Securities qualifying for exception from tax reporting as described in Treas. Reg. 1.671-5(c)(2)(iv)(G) and, during the final calendar year of the trust, qualifying for the exception from tax reporting described in Treas. Reg. 1.671-5(c)(2)(iv)(F). Notwithstanding the foregoing, neither the Trustee nor the Depositor shall be liable to any person in the event sales proceeds for any calendar year exceed the general de minimis test of Treas. Reg. 1.671-5(c)(2)(iv)(D)(1) (whether or not due to a failure to sell Securities pro rata) or otherwise require reporting under Treas. Reg. 1.671- 5." V. Notwithstanding anything to the contrary in the Standard Terms and Conditions of Trust, Section 6.02 of the Standard Terms is amended to read in its entirety as follows: "Section 6.02. Books, Records and Reports. (a) General. The Trustee shall keep proper books of record and account of all the transactions of each Trust under this Indenture at its corporate trust office, including a record of the name and address of, and the Units issued by each Trust and held by, every Unit holder, and such books and records of each Trust shall be open to inspection by any Unit holder of such Trust at all reasonable times during the usual business hours. The Trustee shall make such annual or other reports as may from time to time be required under any applicable state or federal statute or rule or regulations thereunder. (b) Audit of trust accounts. Unless the Depositor determines that such an audit is not required, the accounts of the Trust shall be audited not less than annually by independent public accountants designated from time to time by the Depositor and the Trustee and the reports of such accountants shall be furnished upon request to Unit holders. So long as the Depositor is making a secondary market for Units, the Depositor shall bear the cost of such annual audits to the extent such cost exceeds $.50 per 100 Units. (c) Costs of updating of registration statement. If provided for in the Prospectus for a Trust, the Trustee shall pay, or reimburse to the Depositor, the expenses related to the updating of the Trust's registration statement, to the extent of legal fees, typesetting fees, electronic filing expenses and regulatory filing fees. Such expenses shall be paid from the Income Account, or to the extent funds are not available in such Account, from the Capital Account, against an invoice or invoices therefor presented to the Trustee by the Depositor. By presenting such invoice or invoices, the Depositor shall be deemed to certify, upon which certification the Trustee is authorized conclusively to rely, that the amounts claimed therein are properly payable pursuant to this paragraph. The Depositor shall provide the Trustee, from time to time as requested, an estimate of the amount of such expenses, which the Trustee shall use for the purpose of estimating the accrual of Trust expenses. The amount paid by the Trust pursuant to this paragraph in each year shall be separately identified in the annual statement provided to Unit holders. The Depositor shall assure that the Prospectus for the Trust contains such disclosure as shall be necessary to permit payment by the Trust of the expenses contemplated by this paragraph under applicable laws and regulations. The provisions of this paragraph shall not limit the authority of the Trustee to pay, or reimburse to the Depositor or others, such other or additional expenses as may be determined to be payable from the Trust as provided in this Section 6.02. (d) Tax reporting for grantor trusts. With respect to any Trust which is a widely held fixed investment trust as defined in Treas. Reg. 1.671- 5(b)(22), the Depositor and the Trustee agree that the Trust meets the requirements of Treas. Reg. 1.671- 5(f)(1)(i), and the Trustee is authorized: (i) to report in accordance with any of the safe harbor methods described in Treas. Reg. 1.671- 5(f); (ii) to report sales proceeds, whenever permitted, as provided in Treas. Reg. 1.671- 5(f)(1)(iv)(B); (iii) to report proceeds of sales and dispositions described in Treas. Reg. 1.671- 5(c)(2)(iv)(D)(4)(ii) as provided in Treas. Reg. 1.671- 5(c)(2)(iv)(D)(4)(i); and (iv) to use the measuring date, as defined in Treas. Reg. 1.671-5(c)(2)(iv)(D)(1), in lieu of the start-up date, wherever permitted. For purposes of Treas. Reg. 1.671-5(f)(1)(iv)(A)(2), the date of the last deposit under 2.01(b) prior to the expiration of the initial offering period, as certified to the Trustee by the Depositor, shall be considered the 'start-up date' of the Trust." W. Notwithstanding anything to the contrary in the Standard Terms and Conditions of the Trust, the eighth paragraph of Section 5.02 of the Standard Terms shall be amended to read in its entirety as follows: Notwithstanding the foregoing provisions of this Section 5.02, the Trustee (or the FTPS Unit Servicing Agent in the case of FTPS Units) is hereby irrevocably authorized in its discretion, in the event that the Depositor does not purchase any Units tendered to the Trustee (or the FTPS Unit Servicing Agent in the case of FTPS Units) for redemption, or in the event that a Unit is being tendered by the Depositor for redemption, in lieu of redeeming Units, to sell Units in the over-the-counter market through any broker-dealer of its choice for the account of the tendering Unit holder at prices which will return to the Unit holder an amount in cash, net after deducting brokerage commissions, transfer taxes and other charges, equal to or in excess of the Redemption Value which such Unit holder would otherwise be entitled to receive on redemption pursuant to this Section 5.02. The Trustee (or the FTPS Unit Servicing Agent in the case of FTPS Units) shall pay to the Unit holder the net proceeds of any such sale on the day on which such Unit holder would otherwise be entitled to receive payment of the Redemption Value hereunder. X. Notwithstanding anything to the contrary in the Standard Terms and Conditions of Trust, Section 6.01(l) shall be replaced in its entirety with the following: The Trust may include (I) a letter or letters of credit meeting the requirements of Section 2.05 for the purchase of Securities or Contract Obligations issued by the Trustee in its individual capacity for the account of the Depositor or (II) Securities issued by the Trustee, its parent, or affiliates, and the Trustee may otherwise deal with the Depositor and the Trust with the same rights and powers as if it were not the Trustee hereunder; and Y. Notwithstanding anything to the contrary in the Standard Terms and Conditions of Trust, Section 3.07 shall be amended to add the following immediately after Section 3.07(i): (j) that as a result of the ownership of the Security, the Trust or its Unit holders would be a direct or indirect shareholder of a passive foreign investment company as defined in section 1297(a) of the Internal Revenue Code.
