Delivery of a Call Notice does not give rise to an obligation on the part of the Warrantholder to pay the Call Price.  With respect to each Warrant exercised, if by 4 p.m. New York time on the Business Day prior to the Call Date the applicable Warrantholder has not paid the applicable Call Price for a Warrant to the Warrant Agent, except to the extent the Call Notice relates to a tender offer or redemption of Underlying Securities addressed in Section 1.1(i) below, then the exercise of the applicable Warrant shall be automatically rescinded, the applicable Warrant shall be reinstated, no Call Date with respect thereto shall be deemed to have occurred and no Call Notice deemed given, and the applicable Warrantholder shall be entitled to exercise such reinstated Warrants in the future.

| | (i) | Tender Offer and Redemption.
| | --- | ----------------------------

Each Warrantholder shall specify in its Call Notice if its exercise is in connection with a redemption or tender offer if the specified Call Date will occur on or after the First Regular Call Date.  Any Warrantholder giving a Call Notice with respect to a Call Date prior to the First Regular Call Date shall be deemed to specify that it is exercising its Warrants in connection with a tender offer or redemption.

A Warrantholder specifying or deemed to specify that it is exercising its Warrants in connection with a tender offer for or a redemption of the Underlying Securities shall be deemed to instruct the Trustee to tender the applicable Corresponding Underlying Security Amount in connection with such redemption or tender offer.

To the extent Underlying Securities corresponding to such a deemed instruction to tender are not accepted by the tender offeror or Underlying Security Issuer and paid for in accordance with the terms of the tender offer or redemption, a corresponding number of Warrants shall be reinstated, with exercise thereof rescinded, no Call Date with respect thereto shall be deemed to have occurred and no Call Notice deemed given, with the number of such reinstated Warrants to be allocated among the Warrantholders specifying or deemed to specify exercise in connection with such tender offer or redemption in proportion to the number of Warrants initially so exercised by each, and each such Warrantholder shall be entitled to exercise such reinstated Warrants in the future.  The Warrant Agent shall determine such allocation by notice to the applicable Warrantholders.





| | III-2 | 
| | ----- | 





---







A Warrantholder specifying or deemed to specify that it is exercising its Warrants in connection with a tender offer for or a redemption of the Underlying Securities, to the extent such exercise is not rescinded, shall be entitled to Trust Property in an amount equal to the proceeds of the tender offer or redemption allocable to the applicable Corresponding Underlying Security Amount in excess of the aggregate Call Price for the applicable number of Warrants.

If the Warrant Agent receives a Call Notice or Call Notices with respect to Warrants with an aggregate Corresponding Underlying Security Amount that is less than the aggregate principal amount of Underlying Securities held by the Trust subject to redemption, the Warrant Agent shall determine by notice to the applicable Warrantholders which Warrants are to be terminated in connection with such redemption by allocating the termination of Warrantsprorataamong remaining Warrantholders (including exercising Warrantholders holding unexercised Warrants) in proportion to their holdings of unexercised Warrants.  Warrants so terminated shall be entitled to the applicable Warrant Termination Payment.

If the Warrant Agent receives no Call Notices with respect to a redemption of Underlying Securities, a number of Warrants equal to the aggregate principal amount of Underlying Securities held by the Trust that are redeemed divided by the product of (x) the Security Factor and (y) $1,000, shall be terminated.  The Warrant Agent shall determine by notice to the applicable Warrantholders which Warrants are to be terminated by allocating such termination among Warrantholders in proportion to the number of Warrants held by each.  Warrants so terminated shall be entitled to the applicable Warrant Termination Payment.

Whenever the Warrant Agent is obligated to allocate the termination of Warrantsprorata, and this allocation would result in some Warrants being partially terminated, the Warrant Agent shall randomly re-allocate terminations to the extent necessary to ensure that only whole Warrants are terminated or such that only one Warrant is partially terminated.

| | (j) | Payment of Call Price.
| | --- | ----------------------

Except with respect to Warrants exercised or deemed exercised in connection with a redemption of or tender offer for the Underlying Securities, each exercising Warrantholder shall deposit the applicable Call Price for all Warrants exercised by it with the Warrant Agent no later than the Business Day prior to settlement of exercise.

The Warrant Agent shall notify the Trustee immediately upon its receipt of payment of the applicable 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 Unit Account and application pursuant to the other terms of this Trust Agreement no later than 4 p.m. New York time on the Business Day preceding the Call Date and, pending such transfer, shall hold such amount for the benefit of the Warrantholder in a segregated trust account.

| | (k) | Appointment of Warrant Agent.
| | --- | -----------------------------

The Depositor hereby appoints the Warrant Agent as agent to (i) receive for the benefit of the Warrantholders pending payment to the Trust in connection with exercise of the Warrants from time to time, the Call Price amounts paid to the Warrant Agent, (ii) receive for the benefit of the Warrantholders, in connection with exercise of the Warrants from time to time, the Units

deemed tendered to the Trust pursuant to Section 1.2, and the Trust Property received pursuant to the related Optional Exchange pending delivery thereof to the relevant Warrantholders and (iii) otherwise act on behalf of and for the benefit of the Trust, the Unitholders and the Warrantholders for purposes of this Agreement, and the Warrant Agent accepts such appointment for itself and its successors and assigns, subject to the terms and provisions hereof.

| | (l) | Alternative Exercise
| | --- | --------------------

Notwithstanding any other provision of this Trust Agreement, in connection with any exercise of Warrants, if the Warrantholder beneficially owns Class B Units on the date of such exercise, the portion of the Warrant exercise equal to an amount corresponding to the amount of the Class B Units the Warrantholder beneficially owns shall be designated as an Alternative Exercise.  With respect to any portion of an exercise required to be designated as an Alternative Exercise, the Warrantholder shall reduce the Call Price by the corresponding value of Class B Units it beneficially owns and such Class B Units shall be exchanged for Trust Property in connection with such Alternative Exercise.  No Class B Units will be deemed reissued to the Warrantholder or called in connection with such Alternative Exercise.

As with an exercise that is not an Alternative Exercise, the Callable Series provisions shall automatically cancel and re-issue Class A Units to the Warrantholder, the notice of exercise shall constitute a notice of exchange of the acquired Class A Units together with the applicable beneficially owned Class B Units subject to such Alternative Exercise for Trust Property under the Optional Exchange Under Warrants provisions, and any such notice of exchange may only be revoked or rescinded to the extent the exercise as to Class A Units is revoked or rescinded as specified in the Optional Exchange Under Warrants provisions.

All other provisions of this Trust Agreement shall be appropriately construed to give effect to the purposes of this subsection.

| | (m) | Amendment of Trust Agreement
| | --- | ----------------------------

The Units are currently subject to Call Options and Call Rights granted in favor of the Warrantholders.  Notwithstanding any other provision of this Trust Agreement, the Depositor and Trustee may agree to amend and restate this Trust Agreement from time to time regarding the Warrants, without the consent of the Warrantholders, to provide that Warrantholders shall be entitled to call and receive directly the underlying Trust Property corresponding to the Units that would have been redeemed following an exercise of Warrants, and not to call the Units.  For the avoidance of doubt, such amendment shall not affect the Call Price.  Similarly, nothing in the above should be understood as exempting such amendment from the application of Section 12.01(d) of the Standard Terms for Trust Agreements.

Section 1.2Delivery of Units.  As soon as practicable after each surrender of Warrants in whole or in part on the Call Date and upon satisfaction of all other requirements described in the Warrants and in Section 1.1 hereof, the Warrant Agent shall instruct the Trustee to confirm that the transfer specified under the Callable Series provisions of Schedule I has occurred and to cause a distribution of Trust Property to the Warrantholder as an Optional Exchange taking into account Section 1.1(i) above, if applicable.  A surrender of the Warrants shall be deemed to





| | III-4 | 
| | ----- | 





---





be a simultaneous surrender of the Class A Units and Class B Units acquired in exchange therefor.

If such exercise is in part only, the Warrant Agent shall instruct the Trustee to authenticate new Warrants of like tenor, representing the outstanding Warrants of the Warrantholder and the Warrant Agent shall deliver such Warrants to the Warrantholder.

In each case, the Trustee shall act in accordance with such instructions.

Section 1.3Cancellation and Destruction of Warrants.  All 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 Warrant (other than that reflecting any such transfer or exchange) shall be issued in lieu thereof. The Warrant Agent shall destroy all cancelled Warrants.

Section 1.4No Rights as Holder of Units Conferred by Warrants.  Each Warrantholder agrees that the Warrants do not represent an ownership interest in the Trust or its assets and that none of them shall treat the Warrants as an ownership interest in the Trust for any purpose.

ARTICLE II

RESTRICTIONS ON TRANSFER



Section 2.1Restrictive Legends.  Each Warrant (including each Warrant issued upon the transfer of any Warrant) shall be issued with a legend in substantially the form contained in Exhibit A hereto.

Section 2.2Notice of Proposed Transfer.  Prior to any transfer of any Warrant or portion thereof, the Warrantholder will give 5 Business Days (or such lesser period acceptable to the Warrant Agent) prior written notice to the Warrant Agent and the Depositor of such Warrantholders intention to effect such transfer.

ARTICLE III

REGISTRATION AND TRANSFER OF WARRANTS, ETC.



Section 3.1Warrant Register; Ownership of Warrants.  The Warrant Agent will keep a register in which the Warrant Agent will provide for the registration of Warrants and the registration of transfers of Warrants representing numbers of Warrants. The Trustee and the Warrant Agent may treat the Person in whose name any Warrant is registered on such register as the owner thereof for all purposes, and the Trustee and the Warrant Agent shall not be affected by any notice to the contrary.  The Warrant Agent shall make such adjustments to its records and the register as shall be necessary to reflect terminations and exercise of Warrants.

Section 3.2Transfer and Exchange of Warrants.  (a) No Warrant may be offered, resold, assigned or otherwise transferred (including by pledge or hypothecation) at any time except in accordance with this Section 3.2.





| | III-5 |

(1)Any purchaser or transferee of the Warrants shall represent that it is (A) a qualified institutional buyer as defined in Rule 144A under the Securities Act that (1) is not a broker-dealer that owns and invests on a discretionary basis less than $25 million in securities of issuers that are not affiliated persons of the dealer and (2) is not a plan referred to in paragraph (a)(1)(i)(D) or (a)(1)(i)(E) of Rule 144A or a trust fund referred to in paragraph (a)(1)(i)(F) of Rule 144A that holds the assets of such a plan, if investment decisions with respect to the plan are made by the beneficiaries of the plan, (B) aware that the sale or transfer of the Warrants to it may be made to it in reliance on the exemption from registration provided by Rule 144A under the Securities Act and
(C) acquiring the Warrants for its own account or for one or more accounts, each of which is a qualified institutional buyer, and as to each of which the purchaser or transferee exercises sole investment discretion, and in each case in accordance with any applicable securities laws of any state of the United States and other jurisdictions.

(2)Warrants may not be purchased, held by or transferred to any Person unless that Person is not a Plan, is not a governmental or other plan subject to restrictions substantially similar to Title I of ERISA or Section 4975 of the Code, and is not acquiring the Warrants with the assets of any such Plan or other plan.  Each Person who acquires any Warrant, and each fiduciary which causes any such Person to acquire any Warrant, in its individual as well as its fiduciary capacity, will be deemed by such purchase, holding or acquisition, on each date on which the Warrant is held by such person, to have represented that it is not a Plan or any governmental or other plan subject to requirements substantially similar to Title I of ERISA or Section 4975 of the Code and is not using the assets of
any such Plan to purchase those Warrants.  Each Person that acquires a Warrant, and each fiduciary who causes a person to acquire a Warrant, in its individual as well as its fiduciary capacity, agrees to indemnify and hold harmless the Depositor, the Trustee, the Warrant Agent, MS&Co., each Distribution Participant and their respective affiliates from any cost, damages, loss or expense, incurred by them as a result of the representations contained in this Section 3.2(a)(2) not being true.

(b)Upon surrender of any Warrant for registration of transfer or for exchange to the Warrant Agent, the Warrant Agent shall (subject to compliance with Section 3.2(a)) promptly execute and deliver, and cause the Trustee, on behalf of the Trust, to execute and deliver, in exchange therefor, a new Warrant of like tenor and evidencing a like number of Warrants, in the name of such Warrantholder or as such Warrantholder (upon payment by such Warrantholder of any applicable transfer taxes or government charges) may direct; provided that as a condition precedent for transferring the Warrants, the prospective transferee shall deliver to the Trustee and the Depositor an executed copy of the Transfer Letter in the form of Exhibit C hereto.

(c)Any purported transfer of the Warrants (or any interest therein) in violation of Section 3.2(a)(1) or Section 3.2(a)(2) hereof shall be voidab initioand the purported transferee in such transfer shall not be recognized by any Person as a holder of such Warrants for any purpose.  The Depositor and the Trustee shall each have the power to sell the Warrants (or any interest therein) of a purported Warrantholder (or owner of any interest therein) who acquired its interest in violation of Section 3.2(a)(1) or Section 3.2(a)(2) or who continues to hold Warrants in violation of Section 3.2(a)(2).

Section 3.3Replacement of Warrants.  Upon receipt of evidence reasonably satisfactory to the Warrant Agent of the loss, theft, destruction or mutilation of any Warrant and,





| | III-6 | 
| | ----- | 





---





in the case of any such loss, theft or destruction of any Warrant, upon delivery of an indemnity bond in such reasonable amount as the Warrant Agent may determine, or, in the case of any such mutilation, upon the surrender of such Warrant for cancellation to the Warrant Agent, the Warrant Agent shall execute and deliver, and cause the Trustee, on behalf of the Trust, to execute and deliver, in lieu thereof, a new Warrant of like tenor bearing a number not contemporaneously outstanding.

| | Section 3.4 | Execution and Delivery of Warrants by Trustee; Authentication.
| | ----------- | --------------------------------------------------------------

The Trustee agrees and acknowledges that it will, concurrently with the receipt by it of the Underlying Securities and the execution, authentication and delivery of Units, cause to be executed, authenticated and delivered to or upon the order of the Depositor, Warrants duly executed and authenticated by or on behalf of the Trustee.

The Trustee, on behalf of the Trust, hereby agrees (subject to compliance with Article II) to execute and deliver such new Warrants issued in accordance with Section 1.2 or this Article III as the Warrant Agent shall request in accordance herewith.

Upon surrender for registration of transfer of any Warrant at the office or agency of the Trustee, if the requirements of Section 8-401 of the Uniform Commercial Code are met to the Trustees satisfaction, and subject to the transfer restrictions set forth in this Schedule III, the Trustee shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Warrants.  All transfers of Warrants are subject to the approval of the Trustee and the Trustee shall not register any transfer of Warrants if such transfer would violate any provision of the Trust Agreement.

Section 3.5Federal Income Tax Matters.  Each Warrantholder agrees to treat each Warrant as a call option for federal income tax purposes.

ARTICLE IV

WARRANT AGENT



Section 4.1Limitation on Liability.  The Warrant Agent shall be protected and shall incur no liability for or in respect of any action taken, suffered or omitted by it in connection with its administration of the Warrants in reliance upon any instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement or other paper or document in good faith believed by it to be genuine and to be signed, executed and, where necessary, verified and acknowledged, by the proper Person or Persons.  The Warrant Agent and any director, officer, employee or agent of the Warrant Agent shall be indemnified by the Depositor to the same extent that the Trustee is indemnified by the Depositor pursuant to Section 10.05(b) of the
Standard Terms.

Section 4.2Duties of Warrant Agent.  The Warrant Agent undertakes only the specific duties and obligations imposed hereunder upon the following terms and conditions, by all of which the Depositor, the Trust, the Trustee and each Warrantholder shall be bound:

---







(a)The Warrant Agent may consult with legal counsel (who may be legal counsel for the Depositor), and the opinion of such counsel shall be full and complete authorization and protection to the Warrant Agent as to any action taken or omitted by it in good faith and in accordance with such opinion, provided the Warrant Agent shall have exercised reasonable care in the selection by it of such counsel.

(b)Whenever in the performance of its duties hereunder, the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Depositor or the Trustee prior to taking or suffering any action hereunder, such fact or matter may be deemed to be conclusively proved and established by a Depositor Order or a certificate signed by a Responsible Officer of the Trustee and delivered to the Warrant Agent; and such certificate shall be full authorization to the Warrant Agent for any action taken or suffered in good faith by it hereunder in reliance upon such certificate.

(c)The Warrant Agent shall be liable hereunder only for its own negligence, willful misconduct or bad faith.

(d)The Warrant Agent shall not be liable for or by reason of any of the statements of fact or recitals contained herein or be required to verify the same, but all such statements and recitals are and shall be deemed to have been made by the Trust and the Depositor only.

(e)The Warrant Agent shall not have any responsibility in respect of and makes no representation as to the validity of the Warrants or the execution and delivery thereof (except the due execution hereof by the Warrant Agent); nor shall it be responsible for any breach by the Trust of any covenant or condition contained in the Warrants; nor shall it by any act thereunder be deemed to make any representation or warranty as to the Units to be purchased thereunder.

(f)The Warrant Agent is hereby authorized and directed to accept instructions with respect to the performance of its duties hereunder from the Chairman of the Board, the Chief Executive Officer, Chief Financial Officer, Chief Operating Officer, President, a Vice President, a Senior Vice President, a Managing Director, its Treasurer, an Assistant Treasurer, its Secretary or an Assistant Secretary of the Depositor, and any Responsible Officer of the Trustee, and to apply to such officers for advice or instructions in connection with its duties, and it shall not be liable for any action taken or suffered to be taken by it in good faith in accordance with instructions of any such officer.

(g)The Warrant Agent and any shareholder, director, officer or employee of the Warrant Agent may buy, sell or deal in any of the Warrants or other securities of the Trust or otherwise act as fully and freely as though it were not Warrant Agent hereunder, so long as such persons do so in full compliance with all applicable laws. Nothing herein shall preclude the Warrant Agent from acting in any other capacity for the Trust, the Depositor or for any other legal entity.

(h)The Warrant Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys or agents.

(i)The Warrant Agent shall act solely as the agent of the Trust, the Unitholders and the Warrantholders hereunder as respectively set forth herein. The Warrant Agent shall not be





| | III-8 | 
| | ----- | 





---





liable except for the failure to perform such duties as are specifically set forth herein, and no implied covenants or obligations shall be read into the Warrants against the Warrant Agent, whose duties shall be determined solely by the express provisions thereof. The Warrant Agent shall not be deemed to be a fiduciary.

(j)The Warrant Agent shall not be responsible for any failure on the part of the Trustee to comply with any of its covenants and obligations contained herein.

(k)The Warrant Agent shall not be required to expend or risk its own funds or otherwise incur financial liability in the performance of its duties hereunder and shall not be under any obligation or duty to institute, appear in or defend any action, suit or legal proceeding in respect hereof, in each case unless first indemnified to its satisfaction, but this provision shall not affect the power of the Warrant Agent to take such action as the Warrant Agent may consider proper, whether with or without such indemnity. The Warrant Agent shall promptly notify the Depositor and the Trustee in writing of any claim made or action, suit or proceeding instituted against it arising out of or in connection with the Warrants.

(l)The Trustee will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further acts, instruments and assurances as may be required by the Warrant Agent in order to enable it to carry out or perform its duties hereunder.

The Warrant Agent may resign and be discharged from its duties hereunder upon thirty (30) days notice in writing mailed to the Depositor and the Trustee by registered or certified mail, and to the Warrantholders by first-class mail at the expense of the Depositor; provided that no such resignation or discharge shall become effective until a successor Warrant Agent shall have been appointed hereunder.

Warrant Agent shall have been appointed hereunder. If the Warrant Agent shall resign or be removed or shall otherwise become incapable of acting, the Depositor shall promptly appoint a successor to the Warrant Agent, which may be designated as an interim Warrant Agent. If an interim Warrant Agent is designated, the Depositor shall then appoint a permanent successor to the Warrant Agent, which may be the interim Warrant Agent. If the Depositor shall fail to make such appointment of a permanent successor within a period of thirty (30) days after such removal or within sixty (60) days after notification in writing of such resignation or incapacity by the resigning or incapacitated Warrant Agent or by the Warrantholder, then the Warrant Agent or registered Warrantholder may apply to any court of competent jurisdiction for the appointment of such a successor.

Any successor to the Warrant Agent appointed hereunder must be rated in one of the four highest rating categories by the Rating Agencies. Any entity which may be merged or consolidated with or which shall otherwise succeed to substantially all of the trust or agency business of the Warrant Agent shall be deemed to be the successor Warrant Agent without any further action.



Section 4.4Warrant Agent Transfer Fee. The Warrant Agent will assess a fee of $50.00 upon the issue of any new Warrant, such fee to be assessed upon the new Warrantholder.

Ladies and Gentlemen:

In connection with its proposed purchase of Warrants (the Warrants) which represent the right to call $______________ aggregate Unit Principal Balance of SATURNS 2006-1 Tribune Company Debenture Backed Class A Units and the Applicable Class B Equivalent Amount of SATURNS 2006-1 Tribune Company Debenture-Backed Class B Units, the undersigned transferee (the Transferee) confirms that:

1.The Transferee understands that substantial risks are involved in an investment in the Warrants. The Transferee represents that in making its investment decision to acquire the Warrants, the Transferee has not relied on representations, warranties, opinions, projections, financial or other information or analysis, if any, supplied to it by any person, including MS&Co., MS Structured Asset Corp., as depositor (the Depositor), or LaSalle Bank National Association, as trustee (the Trustee), or any of your or their affiliates, except as expressly contained in written information, if any. The Transferee has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Warrants,
and the Transferee is able to bear the substantial economic risks of such an investment. The Transferee has relied upon its own tax, legal and financial advisors in connection with its decision to purchase the Warrants.

2.Such Transferee (A) is a qualified institutional buyer (as defined in Rule 144A of the Securities Act) that (1) is not a broker-dealer that owns and invests on a discretionary basis less than $25 million in securities of issuers that are not affiliated persons of the dealer and (2) is not a plan referred to in paragraph (a)(1)(i)(D) or (a)(1)(i)(E) of Rule 144A or a trust fund referred to in paragraph (a)(1)(i)(F) of Rule 144A that holds the assets of such a plan, if investment decisions with respect to the plan are made by the beneficiaries of the plan, (B) is aware that the sale or transfer of the Warrants to it may be made to it in reliance on the exemption from registration provided by Rule 144A under the Securities Act and (C) is acquiring the Warrants for its
own account or for one or more accounts, each of which is a qualified institutional buyer, and as to each of which the Transferee exercises sole investment discretion, and in each case in accordance with any applicable securities laws of any state of the United States and other jurisdictions.

3.The Transferee understands that the Warrants have not been and will not be registered under the 1933 Act or under the securities or blue sky laws of any state, and that (i) if it decides to resell, pledge or otherwise transfer any Security, such resale, pledge or other transfer must comply with the provisions of the Trust Agreement relating to the Warrants and (ii) it will, and each subsequent holder will be required to, notify any purchaser of any Warrant from it of the resale restrictions in the Trust Agreement.

4.The Transferee understands that each of the Warrants will bear a legend substantially to the following effect, unless otherwise agreed by the Depositor and the Trustee:

EACH PURCHASER OR OTHER TRANSFEREE OF THIS WARRANT OR ANY INTEREST HEREIN OF THIS WARRANT, BY ITS ACCEPTANCE HEREOF, IS DEEMED TO REPRESENT AND WARRANT FOR THE BENEFIT OF THE TRUSTEE AND THE DEPOSITOR OF THE TRUST, AND EACH DISTRIBUTION PARTICIPANT AS DEFINED IN THE TRUST AGREEMENT THAT SUCH PURCHASER OR OTHER TRANSFEREE IS A QUALIFIED INSTITUTIONAL BUYER AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT.

THE HOLDER, AND EACH FIDUCIARY WHICH CAUSES ANY PERSON TO ACQUIRE ANY WARRANT, IN ITS INDIVIDUAL AS WELL AS ITS FIDUCIARY CAPACITY, WILL BE DEEMED BY SUCH PURCHASE, HOLDING OR ACQUISITION, ON EACH DATE ON WHICH THE WARRANT IS HELD BY SUCH PERSON, TO HAVE REPRESENTED THAT IT IS NOT A (I) EMPLOYEE BENEFIT PLAN (AS DEFINED IN SECTION 3(3) OF THE EMPLOYEE RETIREMENT INCOME SECURITY ACT OF 1974, AS AMENDED (ERISA)) SUBJECT TO THE FIDUCIARY RESPONSIBILITY PROVISIONS OF TITLE I OF ERISA, (II) PLAN DESCRIBED IN SECTION 4975(E)(1) OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE CODE) SUBJECT TO SECTION 4975 OF THE CODE, (III) ENTITY WHOSE UNDERLYING ASSETS INCLUDE PLAN ASSETS BY REASON OF A PLANS INVESTMENT IN SUCH ENTITY OR OTHERWISE OR (IV) GOVERNMENTAL OR OTHER PLAN SUBJECT TO REQUIREMENTS SUBSTANTIALLY SIMILAR TO TITLE I OF ERISA OR
SECTION 4975 OF THE INTERNAL REVENUE CODE.

EACH PERSON THAT ACQUIRES A WARRANT, AND EACH FIDUCIARY WHO CAUSES A PERSON TO ACQUIRE A WARRANT, IN ITS INDIVIDUAL AS WELL AS ITS FIDUCIARY CAPACITY, AGREES TO INDEMNIFY AND HOLD HARMLESS THE DEPOSITOR, THE TRUSTEE, THE WARRANT AGENT, MS&CO. AND THEIR RESPECTIVE AFFILIATES FROM ANY COST, DAMAGES, LOSS OR EXPENSE, INCURRED BY THEM AS A RESULT OF THE REPRESENTATIONS MADE BY SUCH PERSON OR FIDUCIARY IN THIS PARAGRAPH NOT BEING TRUE.

The Transferee and each such fiduciary understands that the representations made in this section 5 will be deemed made on each day from the date hereof through and including the date on which the Transferee disposes of the Warrants.  The Transferee and each fiduciary who causes the Transferee to acquire a Warrant, in its individual as well as its fiduciary capacity, agrees to
indemnify and hold harmless the Depositor, the Trustee, the Warrant Agent, MS&Co., each Distribution Participant and their respective affiliates from any cost, damages, loss or expense, incurred by them as a result of the representations made in this paragraph not being true.

6.The Transferee understands that no subsequent transfer of the Warrants is permitted unless such transfer is to a transferee who will own, after giving effect to such transfer and any other simultaneous transfers, at least 250 Warrants and the Transferee causes the proposed transferee to provide to the Depositor and the Trustee such documentation as may be required pursuant to Section 3.2 of the Warrant Agent Agreement, including, if required, a letter substantially in the form hereof, or such other written statement as the Depositor shall reasonably prescribe.
