to time direct the Trustee to  authenticate  and deliver,  on behalf of any such

Certificates,  the "Certificates").  The Trust also is issuing call options with
respect to $30,000,000 principal amount of Term Assets (the "Call Warrants").

evidence undivided  ownership  interests in the assets of the Trust,  subject to
the  liabilities  of the Trust and shall be  payable  solely  from  payments  or
property received by the Trustee on or in respect of the Term Assets.  The Class
A Certificates  will represent the entire beneficial  ownership  interest in the
principal and redemption premium, if any, of the Term Assets, and will represent
a  beneficial  ownership  interest in the  interest  received on the Term Assets
equal to the Class A Fixed Payments. The Class B Certificates will


                                        6



represent a beneficial  ownership  interest in the interest received on the Term
Assets equal to the Class B Fixed Payments. The Class A Certificates and Class B
Certificates  will rank pari passu with  respect  to its  respective  beneficial
ownership  interest in the  interest  payments on the Term Assets and will share
proportionately in such interest based upon the accrued and unpaid Class A Fixed
Payments and the accrued and unpaid Class B Fixed Payments.

     Section  4.  Date  of  the   Certificates.   The   Certificates   that  are
authenticated  and  delivered by the Trustee to or upon  Depositor  Order on the
Closing Date shall be dated the Closing Date.  All other  Certificates  that are
authenticated  after the Closing Date for any other  purpose under the Agreement
shall be dated the date of their authentication.

     Section 5. Class A Certificate Principal Balance and Denominations; Class B
Certificates;  Additional  Term Assets.  On the Closing Date,  1,200,000 Class A
Certificates  with a  Certificate  Principal  Balance  of  $30,000,000  shall be
authenticated  and  delivered  under the Base Trust  Agreement  and this  Series
Supplement.  In  addition,  on the Closing  Date,  Class B  Certificates  with a
Notional Amount of $30,000,000  shall be  authenticated  and delivered under the
Base Trust  Agreement  and this Series  Supplement.  The  Certificate  Principal
Balance  of the  Class A  Certificates  and the  Notional  Amount of the Class B
Certificates  shall each initially  equal the initial  principal  amount of Term
Assets  sold  to the  Trustee  and  deposited  in the  Trust.  Such  Certificate
Principal  Balance and Notional  Amount shall be  calculated  without  regard to
Class A Certificates and Class B Certificates,  respectively,  authenticated and
delivered upon  registration of, transfer of, or in exchange for, or in lieu of,
other Class A Certificates or Class B Certificates pursuant to Sections 5.3, 5.4
or 5.5 of the Base  Trust  Agreement.  The  Depositor  may  sell to the  Trustee
additional  Term Assets on any date  hereafter  upon at least five (5)  Business
Days  notice to the  Trustee  and upon (i)  satisfaction  of the  Rating  Agency
Condition and (ii) delivery of an Opinion of Counsel to the effect that the sale
of such additional Term Assets will not materially  increase the likelihood that
the Trust  would fail to qualify as a grantor  trust  under the Code and, in any
event,  that the Trust  will not fail to  qualify  as either a grantor  trust or
partnership (other than a publicly traded partnership  treated as a corporation)
under the Code.  Each  condition to be satisfied  with respect to a sale of Term
Assets on or prior to the Closing Date shall be satisfied with respect to a sale
of  additional  Term  Assets  no  later  than  the  date of sale  thereof,  each
representation and warranty set forth in the Agreement to be made on the Closing
Date  shall be made on such date of sale with  respect  to the  additional  Term
Assets,  and from and  after  such  date of sale,  all Term  Assets  held by the
Trustee  shall be held on the same terms and  conditions.  Upon such sale to the
Trustee,   the  Trustee  shall  deposit  such  additional  Term  Assets  in  the
Certificate Account, and shall authenticate and deliver to the Depositor, or its
order,  Class A  Certificates  in a  Certificate  Principal  Balance and Class B
Certificates  in a  Notional  Amount  equal  to the  principal  amount  of  such
additional  Term Assets.  Any such additional  Class A Certificates  and Class B
Certificates  authenticated and delivered shall rank pari passu with any Class A
Certificates  or  Class  B  Certificates,  respectively,  previously  issued  in
accordance with this Series Supplement.

     Section  6.  Currency  of  the  Certificates.   All  distributions  on  the
Certificates will be made in the Specified Currency.


                                        7



     Section 7. Form of  Securities.  The Trustee  shall execute and deliver the
Certificates  in the form of one or more global  certificates  registered in the
name of DTC or its nominee.

     Section 8. Call  Warrants.  (a)  Concurrently  with the  execution  of this
Series  Supplement,  the  Trustee,  on behalf of the Trust,  shall  execute  the
Warrant  Agent  Agreement  and one or more Call  Warrants,  dated as of the date
hereof and substantially in the form of Exhibit E 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.

     (b) The Trustee may not enter into any  amendment  or  modification  of the
Call Warrant except as provided in Section VI.4 of the Call Warrant.

     (c) The Trustee shall notify the Certificateholders and the Rating Agencies
upon receipt of any notice, pursuant to the provision of the Call Warrants, of a
Warrantholder's  intent to  exercise  its Call  Warrants.  Such  notice from the
Trustee shall state (i) the Warrant  Exercise  Date,  (ii) that such exercise of
the Call  Warrant is  conditional  upon  receipt by the  Trustee of the  Warrant
Exercise  Purchase Price with respect to such  exercise,  (iii) that the Trustee
will select by lot for  redemption  a principal  amount of Class A  Certificates
equal to the  principal  amount  of Term  Assets to be  purchased  and that such
redemption of the Class A Certificates  will occur on the Warrant  Exercise Date
at a price equal to $25 per Class A Certificate plus accrued and unpaid interest
to the date of redemption and (iv) that on the date of  redemption,  the Class B
Certificateholders  will be paid  accrued  and  unpaid  interest  on the Class B
Certificates  to the date of redemption  and that  following such payment on the
Class B Certificates  the Notional  Amount of the Class B  Certificates  will be
reduced by the  principal  amount of Term Assets  purchased.  A holder of a Call
Warrant may rescind its notice  given  pursuant to the terms of the Call Warrant
and any  rescission  of such  notice  or  failure  to pay the  Warrant  Exercise
Purchase  Price  pursuant to a rescinded  notice shall not adversely  affect the
right of a  Warrantholder  to deliver a notice  thereafter.  The  Trustee  shall
promptly notify  Certificateholders  of any rescission of such a notice and that
the  redemption  of  Certificates  in  connection  with  such  exercise  is also
rescinded.

     (d) Upon the exercise of any Call Warrant in  accordance  with the terms of
the Call Warrants,  the Trustee,  after receipt of the Warrant Exercise Purchase
Price  and the Call  Warrants  being  exercised,  shall  deliver  or cause to be
delivered  upon the written  direction of the Warrant  Agent,  by 1:00 p.m. (New
York  City  time) on the  related  Warrant  Exercise  Date,  the Term  Assets as
specified in the exercised Call Warrant by instructing  the Depositary to credit
such Term Assets to the account of the exercising  Warrantholder or its nominee,
provided  that the Trustee  shall have  received  notice of the exercise of such
Call Warrant  from the Warrant  Agent in  accordance  with the terms of the Call
Warrants  and  shall  have  received  from  the  Warrant  Agent  an  amount,  in
immediately  available funds in a form  acceptable to the Trustee,  equal to the
Warrant Exercise Purchase Price for such Term Assets by 1:00 p.m. (New York City
time) on the related Warrant  Exercise Date. If any Call Warrant is exercised in
connection with a partial  redemption of Term Assets,  the Trustee shall, to the
extent possible, deliver to the exercising Warrantholder,  Term Assets that have
been selected for redemption.

     (e) Upon receipt of the Warrant  Exercise  Purchase  Price pursuant to this
Section


                                       8



8 and the Call Warrants being exercised, the Trustee shall deposit the amount of
the Warrant Exercise Purchase Price in the Certificate  Account on or before the
related Warrant Exercise Date and pay to the Class A Certificateholders  and the
Class B  Certificateholders  the amount described in Section  8(c)(iii) and (iv)
above.  The Class A Certificates  to be redeemed will be selected by the Trustee
or DTC by lot  and  will be  paid  for on the  Warrant  Exercise  Date,  and the
Notional Amount of the Class B Certificates  will be reduced pro rata based upon
the Notional Amount of Class B Certificates held by a Class B Certificateholder.

     Section 9 Certain  Provisions of Base Trust Agreement Not  Applicable.  The
provisions of Sections 2.3, 3.2,  3.3,  3.4, 3.5, 3.6, 3.8,  3.10,  3.11,  3.12,
3.13,  5.16,  5.17,  6.1(c) through (e), 6.6 and 9.1 of the Base Trust Agreement
and any other provision of the Base Trust Agreement,  which imposes  obligations
on, or creates  rights in favor of, the Trustee or the  Certificateholders  as a
result of or in connection with an "Event of Default" or  "Administrative  Agent
Termination  Event" shall be inapplicable with respect to the  Certificates.  In
addition,   there  is  no  "Administrative  Agent"  specified  herein,  and  all
references  to  "Administrative  Agent" in the Base Trust  Agreement,  therefore
shall be inapplicable with respect to the Certificates.

     Section 10. Distributions.

     (a) On each Scheduled  Distribution  Date, the Trustee shall  distribute to
the Class A  Certificateholders  the  related  Class A Fixed  Payment  and shall
distribute to the Class B Certificateholders  the related Class B Fixed Payment,
to the extent of Interest Collections, and on the Maturity Date shall distribute
to  the  Class  A  Certificateholders  the  principal  balance  of the  Class  A
Certificates (in the amount of $30,000,000),  to the extent the principal of the
Term Assets is received by the Trustee on such date,  and shall  distribute  all
other  amounts  held in the  Trust  pursuant  to  Section  10(k) of this  Series
Supplement;  provided,  however,  if any such  payment  with respect to the Term
Assets is made to the Trustee  after the Term Assets  Payment Date on which such
payment  was due,  the Trustee  shall  distribute  such  amount  received on the
Business Day  following  such receipt.  In the event the Extension  Period is in
effect,  interest  distributions  on the Class A  Certificates  will continue to
accrue at a rate of 7.75% per annum and  interest  distributions  on the Class B
Certificates  will  continue to accrue at a rate of .455% per annum,  so long as
interest on the Junior Subordinated  Deferrable Interest Debentures continues to
so accrue,  but the Trustee shall not be required to make any  distributions  on
the Certificates until the next Scheduled Distribution Date following the end of
the Extension Period.

     (b) In the event of a Payment  Default,  the Trustee shall proceed  against
the Term Assets Issuer on behalf of the  Certificateholders  to enforce the Term
Assets or otherwise to protect the interests of the Certificateholders,  subject
to the receipt of indemnity in form and substance  satisfactory  to the Trustee;
provided that,  holders of the Class A  Certificates  representing a majority of
the Voting  Rights on the Class A  Certificates  will be  entitled to direct the
Trustee in any such  proceeding  or direct the Trustee to sell the Term  Assets,
subject to the Trustee's  receipt of satisfactory  indemnity.  If the Trustee is
directed to sell the Term Assets, the Trustee shall solicit bids for the sale of
the Term Assets 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 shall be deemed to qualify as leading dealers:  (1) Credit
Suisse First Boston Corporation,  (2) Goldman,  Sachs & Co., (3) Lehman Brothers
Inc., (4) Merrill Lynch,


                                       9



Pierce,  Fenner & Smith  Incorporated,  (5) UBS  Securities  LLC and (6) Salomon
Smith Barney Inc.; provided, however, that no bid from Salomon Smith Barney Inc.
or any affiliate  thereof shall be accepted unless such bid equals the then fair
market value of such Term Assets.  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 Term Assets 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
Acceleration and a corresponding  payment on the Term Assets,  the Trustee shall
distribute  the  proceeds to the Class A  Certificateholders  and, to the extent
such proceeds  represent  scheduled interest payments on the Term Assets, to the
Class B Certificateholders up to the amount of the accrued interest based on the
Notional  Amount,  no later  than two (2)  Business  Days  after the  receipt of
immediately available funds.

     (c) In the event  that the  Trustee  receives  money or other  property  in
respect of the Term Assets (other than a scheduled payment on or with respect to
an interest  payment  date) as a result of a Payment  Default on the Term Assets
(including  from the sale  thereof),  the Trustee will  promptly  give notice as
provided in Section 18(c) to the Depositary,  or for any Certificates  which are
not then held by DTC or any other depository, directly to the registered holders
of the Certificates  then outstanding and unpaid.  Such notice shall state that,
not later than 30 days after the receipt of such moneys or other  property,  the
Trustee  will  allocate  and  distribute  such  moneys or other  property to the
holders of Class A Certificates  pro rata by principal amount and, to the extent
such proceeds represent scheduled interest on the Term Assets, to the holders of
the  Class B  Certificates  up to the  accrued  interest  thereon,  pro  rata by
Notional Amount (after deducting the costs incurred in connection  therewith and
subject  to clause (l) of this  Section  10).  Property  other than cash will be
liquidated by the Trustee, and the proceeds thereof distributed in cash, only to
the extent necessary to avoid  distribution of fractional  securities to Class A
Certificateholders.  Other than as provided in clause (l) below,  no amount will
be distributed to the Depositor in respect of the Term Assets.

     (d) Distributions to the  Certificateholders on each Distribution Date will
be made to the Certificateholders of record on the Record Date.

     (e) All distributions  (other than  distributions  made pursuant to section
10(g)) to Class A Certificateholders shall be allocated pro rata among the Class
A Certificates  based on their  respective  principal  balances as of the Record
Date. All  distributions  to Class B  Certificateholders  shall be allocated pro
rata among the Class B Certificates based on their respective Notional Amount as
of the Record Date.

     (f) Notwithstanding any provision of the Agreement to the contrary,  to the
extent funds are  available,  the Trustee will initiate  payment in  immediately
available funds by 10:00 A.M. (New York City time) on each  Distribution Date of
all amounts  payable to each  Certificateholder  with respect to any Certificate
held by such  Certificateholder  or its nominee  (without the  necessity for any
presentation  or surrender  thereof or any notation of such payment  thereon) in
the manner and at the  address as each  Certificateholder  may from time to time
direct the Trustee in writing fifteen (15) days prior to such  Distribution Date
requesting that such payment will be so made and designating the bank account to
which such payments  shall be so made.  The Trustee shall be entitled to rely on
the last instruction delivered by the


                                       10



Certificateholder  pursuant to this Section  10(f) unless a new  instruction  is
delivered fifteen (15) days prior to a Distribution Date.

     (g) Upon  receipt by the  Trustee of a notice  that all or a portion of the
Term Assets are to be redeemed, the Trustee shall select by lot for redemption a
principal  amount of Class A Certificates  and reduce the Notional Amount of the
Class B  Certificates  equal to the  principal  amount of the Term  Assets to be
redeemed on the Term Assets  Redemption  Distribution  Date.  The Trustee  shall
promptly  give notice of such  redemption to the  Warrantholder.  Notice of such
redemption   shall   also  be   given   by  the   Trustee   to  the   registered
Certificateholders  not less than  fifteen  (15) days  prior to the Term  Assets
Redemption  Distribution  Date by mail to each registered  Certificateholder  at
such registered  Certificateholder's  last address on the register maintained by
the Trustee;  provided,  however, that the Trustee shall not be required to give
any  notice  of  redemption  prior to the third  business  day after the date it
receives notice of such redemption. Subject to the exercise of the Call Warrants
(in which case the  provisions  of  Section 8 of this  Series  Supplement  shall
apply), the redemption price for the Class A Certificates  redeemed shall be $25
per  Class A  Certificate  plus  accrued  and  unpaid  interest  to the  date of
redemption  plus a pro rata share of the redemption  premium,  if any,  received
from the Term Assets  Issuer.  In addition,  the Trustee will pay to the Class B
Certificateholders  accrued and unpaid  interest to the date of redemption,  but
solely to the extent of amounts  received  on the Term  Assets  which  represent
interest on the Term Assets,  and will reduce the Notional Amount of the Class B
Certificates,  pro rata based on the Notional Amount held, by an amount equal to
the principal amount of the Term Assets redeemed.

     (h) AON will have the right to prepay  the Junior  Subordinated  Deferrable
Interest  Debentures  in whole  but not in part,  within 90 days  following  the
occurrence of a Tax Event or an Investment  Company Event (together with the Tax
Event, a "Special  Event"),  and therefore  cause a mandatory  redemption of the
Term Assets.  The redemption  price in the case of a redemption  following a Tax
Event or an  Investment  Company Event will equal the greater of (i) 100% of the
principal amount of the Junior  Subordinated  Deferrable  Interest Debentures or
(ii) the sum of the present value of 100% of the principal  amount that would be
payable on  January  1, 2027,  together  with the  present  values of  scheduled
payments of interest from the  redemption  date to January 1, 2027, in each case
discounted to the redemption date on a semiannual basis (assuming a 360-day year
consisting  of twelve  30-day  months) at a certain  treasury rate plus 50 basis
points,  plus,  in  each  case,  accrued  interest  on the  Junior  Subordinated
Deferrable Interest Debentures to the date of redemption.

     (i) In the event the Junior Subordinated Deferrable Interest Debentures are
distributed  to the  Trust as a result  of the  liquidation  of the Term  Assets
Issuer,  such  distribution  will not cause  the  Certificates  to be  redeemed.
Instead,  the  Trust  will  hold the  Junior  Subordinated  Deferrable  Interest
Debentures for the  Certificateholders  in accordance  with the terms hereof and
the Base Trust Agreement.

     (j) In the event that  periodic  reports  required to be filed by AON under
the United States Securities  Exchange Act of 1934 are no longer being filed and
the Depositor determines in its sole discretion that under applicable securities
laws, rules or regulations the Trust must be liquidated,  then the Trustee shall
liquidate any remaining  Term Assets and distribute  any proceeds  thereof.  The
distribution will be allocated between the Class A


                                       11



Certificates and the Class B Certificates  such that the percentage  received by
the Class A  Certificateholders  of the total  distribution  equals  the Class A
Proportion  divided  by the  sum of the  Class A  Proportion  plus  the  Class B
Proportion and the percentage received by the Class B Certificateholders  of the
total distribution equals the Class B Proportion divided by the sum of the Class
A Proportion  plus the Class B Proportion.  The Trustee shall notify each Rating
Agency of any such  liquidation  of the Trust.  If the  Trustee is  required  to
liquidate the Term Assets  pursuant to Section 10(j),  the Trustee shall solicit
bids for the sale of the Term  Assets 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  shall be deemed to qualify as
leading dealers: (1) Credit Suisse First Boston Corporation,  (2) Goldman, Sachs
& Co., (3) Lehman  Brothers  Inc.,  (4) Merrill  Lynch,  Pierce,  Fenner & Smith
Incorporated,  (5) UBS  Securities  LLC  and  (6)  Salomon  Smith  Barney  Inc.;
provided,  however,  that no bid from Salomon Smith Barney Inc. or any affiliate
thereof  shall be accepted  unless such bid equals the then fair market value of
such Term Assets. 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 Term Assets 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.

     (k) The  rights  of the  Certificateholders  to  receive  distributions  in
respect of the Certificates, and all interests of the Certificateholders in such
distributions, shall be as set forth in this Series Supplement.  Notwithstanding
anything  in the  Agreement  to the  contrary,  to the extent  there  remains on
deposit monies or property in the Trust after (i) all accrued and unpaid Class A
Fixed Payments and the return of the Certificate  Principal  Balance are made on
the Class A Certificates  and (ii) all accrued and unpaid Class B Fixed Payments
are made on the Class B Certificates, such remaining monies or property shall be
distributed to the Class B  Certificateholders  on a pro rata basis based on the
Notional Amount of Class B Certificates held on the date the final Class B Fixed
Payment was made on the Class B  Certificates.  The  Trustee  shall in no way be
responsible or liable to the  Certificateholders nor shall any Certificateholder
in any way be responsible or liable to any other Certificateholder in respect of
amounts  previously  distributed on the  Certificates  based on their respective
principal balances or Notional Amounts, as the case may be.

     (l) On the  Closing  Date,  as partial  payment  for the Term  Assets,  the
Trustee  shall  deliver to, or at the  direction  of, the  Depositor  all of the
Certificates.  On July 1, 2002, as payment of the balance of the purchase  price
for the Term Assets,  the Trustee  shall pay to the  Depositor  from the Class A
Fixed Payment and the Class B Fixed Payment received on such date, the amount of
the  interest  accrued  on the  Term  Assets  from  January  1,  2002 to but not
including the Closing Date,  which amount  equals  $1,025,625.  In the event the
Class A Fixed  Payment  and the Class B Fixed  Payment  are not  received by the
Trustee on such date or otherwise are insufficient to pay such amount of accrued
interest  to the  Depositor,  the  Depositor  shall  have a claim for the unpaid
portion of such amount and shall share pari passu with the Certificateholders to
the extent of such claim (i) in the  proceeds  from the sale or  recovery of the
Term Assets,  in the case of the Class A Certificates and (ii) in the portion of
such proceeds which represent interest in the case of the Class B Certificates.

     (m)  Any  interest  that  accrues  on the  Junior  Subordinated  Deferrable
Interest  Debentures  during an Extension Period will be distributed on the date
of receipt by the Trustee to


                                       12




Class A Certificateholders  and the Class B  Certificateholders  on a pari passu
basis as follows: (i) to Class A  Certificateholders  all Class A Fixed Payments
which have not been paid during the Extension  Period plus interest on each such
Class A Fixed  Payment  calculated at the stated rate of interest on the Class A
Certificates from the respective Scheduled Distribution Date for each such Class
A Fixed Payment to the date of distribution by the Trustee and (ii) to the Class
B  Certificates  all Class B Fixed  Payments which have not been paid during the
Extension Period plus interest on each such Class B Fixed Payment  calculated at
the stated  rate of  interest on the Class B  Certificates  from the  respective
Scheduled  Distribution  Date for each such Class B Fixed Payment to the date of
distribution by the Trustee. Any monies which remain on deposit after taking the
actions  described  in clause (i) and (ii) shall be  distributed  to the Class B
Certificateholders.

     Section 11.  Termination of Trust.  (a) The Trust shall  terminate upon the
occurrence of any Trust Termination Event.

     (b) Except for any reports and other information required to be provided to
Certificateholders  hereunder  and under the Base Trust  Agreement and except as
otherwise  specified  herein and therein,  the  obligations  of the Trustee will
terminate upon the distribution to Certificateholders of all amounts required to
be  distributed  to them  and the  disposition  of all Term  Assets  held by the
Trustee.  The Trust shall thereupon  terminate,  except for surviving  rights of
indemnity.

     Section  12.  Limitation  of  Powers  and  Duties.  (a) The  Trustee  shall
administer  the Trust and the Term Assets solely as specified  herein and in the
Base Trust Agreement.

     (b) The Trust is  constituted  solely  for the  purpose  of  acquiring  and
holding  the Term  Assets.  The Trustee is not  authorized  to acquire any other
investments  or  engage  in  any  activities  not  authorized   herein  and,  in
particular,  unless  expressly  provided  in the  Agreement,  the Trustee is not
authorized (i) to sell, assign, transfer, exchange, pledge, set-off or otherwise
dispose  of any  of the  Term  Assets,  once  acquired,  or  interests  therein,
including to Certificateholders, (ii) to merge or consolidate the Trust with any
other  entity,  or (iii) to do  anything  that  would  materially  increase  the
likelihood  that the Trust will fail to  qualify  as a grantor  trust for United
States  federal  income tax purposes.  In addition,  the Trustee has no power to
create,  assume or incur  indebtedness  or other  liabilities in the name of the
Trust other than as contemplated herein and in the Base Trust Agreement.

     (c) The parties  acknowledge  that the  Trustee,  as the holder of the Term
Assets,  has the right to vote and give  consents  and waivers in respect of the
Term  Assets  and  enforce  the other  rights,  if any,  of a holder of the Term
Assets,  except as otherwise  limited by the Base Trust Agreement or this Series
Supplement.  In the event  that the  Trustee  receives  a request  from the Term
Assets  Trustee,  the Term Assets Issuer or, if applicable,  the Depositary with
respect  to the  Term  Assets,  for  the  Trustee's  consent  to any  amendment,
modification or waiver of the Term Assets, or any document relating thereto,  or
receives any other  solicitation for any action with respect to the Term Assets,
the Trustee  shall within two (2) Business  Days mail a notice of such  proposed
amendment,    modification,   waiver   or   solicitation   to   each   Class   A
Certificateholder,  Class B Certificateholder  and Warrantholder of record as of
the date of such request.  The Trustee shall request instructions from the Class
A Certificateholders as to what action to take in


                                       13




response  to such  request  and  shall be  protected  in  taking no action if no
direction is received.  Except as otherwise  provided herein,  the Trustee shall
consent or vote, or refrain from  consenting or voting,  in the same  proportion
(based on the  principal  balances of the Class A  Certificates)  as the Class A
Certificates  of the  Trust  were  actually  voted or not  voted by the  Holders
thereof as of the date  determined by the Trustee prior to the date such vote or
consent is required;  provided,  however, that,  notwithstanding anything to the
contrary  in the Base Trust  Agreement  or this Series  Supplement,  the Trustee
shall at no time vote in favor of or consent to any matter (i) which would alter
the  timing or amount of any  payment  on the Term  Assets  (including,  without
limitation, any demand to accelerate the Term Assets) or (ii) which would result
in the exchange or  substitution  of any Term Asset whether or not pursuant to a
plan for the refunding or  refinancing  of such Term Asset,  except in each case
with the unanimous consent of the  Certificateholders  and the unanimous consent
of the  Warrantholders,  and subject to the requirement that such vote would not
materially  increase  the  likelihood  that the Trust  will fail to qualify as a
grantor trust for federal income tax purposes, and, in any event, that the Trust
will not fail to qualify as either a grantor trust or partnership  (other than a
publicly  traded  partnership  treated as a  corporation)  under the Code,  such
determination  to be based  solely on an Opinion of Counsel.  The Trustee  shall
have no  liability  for any failure to act or to refrain  from acting  resulting
from the  Certificateholders'  late return of, or failure to return,  directions
requested by the Trustee from the Certificateholders.

     (d)  Notwithstanding  any provision of the  Agreement to the contrary,  the
Trustee may require  from the  Certificateholders  prior to taking any action at
the  direction  of  the   Certificateholders,   an  indemnity   agreement  of  a
Certificateholder  or any of its Affiliates to provide for security or indemnity
against the costs,  expenses and  liabilities the Trustee may incur by reason of
any such action. An unsecured indemnity agreement, if acceptable to the Trustee,
shall  be  deemed  to be  sufficient  to  satisfy  such  security  or  indemnity
requirement.

     (e)  Notwithstanding  any provision of the  Agreement to the contrary,  the
Trustee shall act as the sole Authenticating Agent, Paying Agent and Registrar.

     Section  13.  Compensation  of Trustee.  Each of the Trustee and U.S.  Bank
National  Association,  as co-trustee (the  "co-trustee"),  shall be entitled to
receive from the Depositor as compensation for its services hereunder, trustee's
fees pursuant to a separate agreement among the Trustee, the co-trustee, and the
Depositor,  and shall be reimbursed for all reasonable  expenses,  disbursements
and advances  incurred or made by it  (including  the  reasonable  compensation,
disbursements and expenses of its counsel and other persons not regularly in its
employ). The Depositor shall indemnify and hold harmless each of the Trustee and
the co-trustee, and its successors, assigns, agents and servants against any and
all loss,  liability or reasonable expense (including  attorneys' fees) incurred
by it in connection with the administration of this trust and the performance of
its duties thereunder. The Trustee and the co-trustee shall notify the Depositor
promptly of any claim for which they may seek indemnity.  Failure by the Trustee
or the co-trustee to so notify the Depositor  shall not relieve the Depositor of
its  obligations  hereunder.  The  Depositor  need not  reimburse any expense or
indemnify against any loss,  liability or expense incurred by the Trustee or the
co-trustee  through the Trustee's or the  co-trustee's  own willful  misconduct,
negligence  or bad faith.  The  indemnities  contained  in this Section 13 shall
survive the resignation or termination of the Trustee or the co-trustee,  or the
termination of this Agreement.


                                       14




     Failure by the Depositor to pay,  reimburse or indemnify the Trustee or the
co-trustee  shall not  entitle  the Trustee or the  co-trustee  to any  payment,
reimbursement or indemnification  from the Trust, nor shall such failure release
either the Trustee or the  co-trustee  from the duties it is required to perform
under this Series Supplement. Any unpaid,  unreimbursed or unindemnified amounts
shall not be borne by the Trust and shall not  constitute  a claim  against  the
Trust,  but  shall be borne by each of the  Trustee  and the  co-trustee  in its
individual  capacity,  and the Trustee and the co-trustee shall have no recourse
against the Trust with respect thereto.

     The  Trustee  hereby  agrees  that it  shall  not  receive  any  additional
compensation  for the  performance  of its  duties,  as warrant  agent under the
Warrant Agreement.

     Section 14. Modification or Amendment. The Trustee shall not enter into any
modification or amendment of the Base Trust Agreement or this Series  Supplement
unless such  modification or amendment is in accordance with Section 10.1 of the
Base Trust  Agreement.  Pursuant  to Section 5 of this  Series  Supplement,  the
Depositor  may sell to the  Trustee  additional  Term  Assets  from time to time
without violation or trigger of this Section 14. Notwithstanding anything to the
contrary  contained in Section 10.1 of the Base Trust Agreement,  the Base Trust
Agreement  or this  Series  Supplement  may not be amended or  modified  for the
purposes contained in items (v) through (viii) in Section 10.1 of the Base Trust
Agreement unless the Trustee has received written  confirmation from each Rating
Agency  that such  amendment  will not  cause  such  Rating  Agency to reduce or
withdraw the then current rating thereof.

     The Required Percentage--Amendment (as defined in the Base Trust Agreement)
referenced in the second proviso of Section  10.1(b) of the Base Trust Agreement
shall be 100%.

     Section  15.  Accounting.  Notwithstanding  Section  3.16 of the Base Trust
Agreement, no such accounting reports shall be required. Pursuant to Section 4.2
of the Base Trust  Agreement,  the  Trustee  shall  cause the  statements  to be
prepared and forwarded as provided therein.

     Section 16. No Investment of Amounts  Received on Term Assets.  All amounts
received on or with respect to the Term Assets shall be held  uninvested  by the
Trustee.

     Section  17. No Event of  Default.  There  shall be no  Events  of  Default
defined with respect to the Certificates.

     Section 18. Notices. (a) All directions,  demands and notices hereunder and
under the Base Trust  Agreement  shall be in writing and shall be deemed to have
been duly given when received if  personally  delivered or mailed by first class
mail,  postage  prepaid or by express  delivery  service or by  certified  mail,

York 10007;  or such other address as the Rating Agency may designate in writing
to the parties hereto.

     (c) In the event a Payment Default or an Acceleration  occurs,  the Trustee
shall promptly give notice to the Depositary or, for any Certificates  which are
not  then  held by the  Depositary  or any  other  depository,  directly  to the
registered holders of the Certificates  thereof. Such notice shall set forth (i)
the  identity  of the  issue of Term  Assets,  (ii) the date and  nature of such
Payment Default or  Acceleration,  (iii) the principal amount of the interest or
principal in default,  (iv) the Certificates  affected by the Payment Default or
Acceleration,  and  (v)  any  other  information  which  the  Trustee  may  deem
appropriate.

     (d)  Notwithstanding  any provisions of the Agreement to the contrary,  the
Trustee shall  deliver all notices or reports  required to be delivered to or by
the Trustee or the Depositor to the  Certificateholders  without  charge to such
Certificateholders.

     Section  19.  Access to  Certain  Documentation.  Access  to  documentation
regarding   the  Term   Assets   will  be   afforded   without   charge  to  any
Certificateholder  so  requesting  pursuant  to  Section  3.17 of the Base Trust
Agreement.  Additionally,  the  Trustee  shall  provide  at the  request  of any
Certificateholder  without charge to such Certificateholder the name and address
of  each   Certificateholder  of  Certificates  hereunder  as  recorded  in  the
Certificate  Register for purposes of  contacting  the other  Certificateholders
with  respect  to  their  rights  hereunder  or for the  purposes  of  effecting
purchases or sales of the Certificates, subject to the transfer restrictions set
forth herein.

     Section 20. Advances.  There is no  Administrative  Agent specified herein;
hence no person  (including the Trustee) shall be permitted or obligated to make
Advances as described in Section 4.3 of the Base Trust Agreement.

     Section 21.  Ratification  of Agreement.  With respect to the Series issued
hereby, the Base Trust Agreement  (including the grant of a security interest in
Section  10.8  of the  Agreement  with  respect  to  the  Term  Assets  conveyed
hereunder),  as  supplemented  by this  Series  Supplement,  is in all  respects
ratified and confirmed,  and the Base Trust Agreement as so supplemented by this
Series  Supplement  shall  be  read,  taken  and  construed  as one and the same
instrument.  To the extent there is any  inconsistency  between the terms of the
Base  Trust  Agreement  and this  Series  Supplement,  the terms of this  Series
Supplement shall govern.

     Section 22.  Counterparts.  This Series  Supplement  may be executed in any
number  of  counterparts,  each of which so  executed  shall be  deemed to be an
original, but all of such counterparts shall together constitute but one and the
same instrument.

     Section 23.  Governing  Law. This Series  Supplement  and each  Certificate
issued  hereunder shall be governed by and construed in accordance with the laws
of the  State of New York  applicable  to  agreements  made and to be  performed
entirely therein without reference


                                       16




to  such  State's  principles  of  conflicts  of  law  to the  extent  that  the
application of the laws of another  jurisdiction would be required thereby,  and
the  obligations,  rights  and  remedies  of  the  parties  hereunder  shall  be
determined in accordance with such laws.

     Section 24. [Reserved]

     Section 25.  Certificate of Compliance.  The Depositor shall deliver to the
Trustee on or prior to June 30 of each year prior to a Trust  Termination  Event
the Officer's  Certificate as to compliance as required by Section 6.1(b) of the
Base Trust Agreement.

     Section 26. Appointment of Co-Trustee. The Depositor and the Trustee hereby
appoint U.S. Bank  National  Association,  a national  banking  association,  as
co-trustee  under the Agreement.  Any action required to be taken by the Trustee
may be  taken  by  U.S.  Bank  National  Association,  as  co-trustee,  in  full
satisfaction of the obligations of the Trustee. By its acceptance of this Series
Supplement,  U.S. Bank National  Association  hereby accepts its  appointment as
co-trustee under the Agreement.

     Section 27. Rule 144A  Provisions  for Class B  Certificates  . The Class B
Certificates  shall be reoffered solely to "qualified  institutional  buyers" as
defined in Rule 144A of the  Securities Act of 1933. All purchasers of the Class
B Certificates, by their purchase, shall be deemed to have represented that they
constitute  "qualified  institutional  buyers"  as  defined  in Rule 144A of the
Securities  Act of 1933.  Further,  at any time when the Trust is not subject to
Section 13 or 15(d) of the United  States  Securities  Exchange Act of 1934,  as
amended,  upon the  request  of any Class B  Certificateholder,  the  Trustee on
behalf of the Trust shall promptly furnish to such Class B Certificateholder  or
to a prospective purchaser of any Class B Certificate designated by such Class B
Certificateholder,  as the case may be,  the  information  which  the  Depositor
determines to be required to be delivered  pursuant to Rule 144A(d)(4) under the
Securities Act ("Rule 144A  Information") in order to permit  compliance by such
Class B  Certificateholder  with Rule 144A in connection with the resale of such
Class B Certificate by such Class B Certificateholder;  provided,  however, that
the Trust shall not be required to provide  audited  financial  statements  more
than once a year or to furnish  Rule 144A  Information  in  connection  with any
request  made on or after the date  that is two years  from the later of (i) the
date such Class B  Certificate  (or any  predecessor  Class B  Certificate)  was
acquired  from  the  Trust or (ii) the date  such  Class B  Certificate  (or any
predecessor  Class B  Certificate)  was last acquired from an "affiliate" of the
Trust  within  the  meaning  of Rule  144,  in each  case as  determined  by the
Depositor.

     Section  28.  Reporting   Obligations.   The  Depositor  shall  advise  and
reasonably  cooperate  with  the  Trustee  as to what  information,  if any,  is
required by Rule  144A(d)(4) of the Securities Act of 1933, as amended,  and the
Trustee shall be entitled to rely on such advice of the Depositor.

     Section 29. Statement of Intent.  It is the intention of the parties hereto
that, for purposes of federal income taxes, state and local income and franchise
taxes and any other taxes imposed  upon,  measured by or based upon gross or net
income,  the Trust shall be treated as a grantor  trust,  but failing that, as a
partnership (other than a publicly traded partnership treated as a corporation).
The parties hereto agree that, unless otherwise required by appropriate tax


                                       17




authorities, the Trust shall file or cause to be filed annual or other necessary
returns, reports and other forms consistent with such intended characterization.
In the event that the Trust is characterized by appropriate tax authorities as a
partnership  for federal  income tax purposes,  each  Certificateholder,  by its
acceptance  of its  Certificate,  agrees to report its  respective  share of the
items of income,  deductions, and credits of the Trust on its respective returns
(making  such  elections  as to  individual  items  as  may be  appropriate)  in
accordance with Treasury Regulations Section 1.761-2 (the "761 Election") and in
a manner  consistent  with the  exclusion  of the  Trust  from  partnership  tax
accounting.  The terms of the Agreement  shall be  interpreted  to further these
intentions of the parties. In mutual consideration for each  Certificateholder's
purchase of a Certificate, each such Certificateholder is deemed to agree not to
delegate  (for a period of more than one year)  authority to  purchase,  sell to
exchange its Certificate to any person.

     Each  Certificateholder  (and each  beneficial  owner of a Certificate)  by
acceptance of its  Certificate  (or its  beneficial  interest  therein)  agrees,
unless otherwise  required by appropriate tax  authorities,  to file its own tax
returns and reports in a manner consistent with the  characterization  indicated
above.

     Section 30. Filing of Partnership  Returns.  In the event that the Trust is
characterized  (by  appropriate  tax  authorities)  as a partnership  for United
States federal  income tax purposes,  and the 761 Election is  ineffective,  the
Depositor  agrees to reimburse  the Trust for any expenses  associated  with the
filing of partnership returns (or returns related thereto).


                                       18




     IN WITNESS WHEREOF,  the parties hereto have caused this Series  Supplement

                                        tax events may occur with respect to the
                                        Term  Assets  Issuer  or AON,  or that a
                                        determination  is  made  that  the  Term
                                        Assets  Issuer is or will be  considered
                                        an   Investment    Company   under   the
                                        Investment   Company  Act  of  1940,  as
                                        amended.


Guarantee                               of AON: AON has  guaranteed  the payment
                                        of  distributions on the Term Assets but
                                        only to the extent  that the Term Assets
                                        Issuer has funds  legally  available for
                                        the  payment of such  distributions  and
                                        cash  sufficient to make such  payments.
                                        AON's   guarantee,    however,   is   an
                                        unsecured  obligation  of AON and  ranks
                                        subordinate  and  junior  to all  senior

evidencing an undivided  interest in the Trust, as defined below,  the assets of
which include Aon Capital A 8.205% Capital Securities, due January 1, 2027.

This Class A Certificate  does not represent an interest in or obligation of the
Depositor or any of its affiliates.

     THIS CERTIFIES THAT Cede & Co. is the registered  owner of a nonassessable,
fully-paid,  fractional undivided interest in CorTS(R) Trust III For Aon Capital
A  (the  "Trust")  formed  by  Structured  Products  Corp.,  as  depositor  (the
"Depositor").

     The Trust was  created  pursuant  to a Base  Trust  Agreement,  dated as of
December 15, 2000 (as amended and supplemented,  the  "Agreement"),  between 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 CorTS(R) Supplement 2002-6,  dated as of May
31, 2002 (the "Series  Supplement" and, together with the Agreement,  the "Trust
Agreement"),  between the  Depositor  and the Trustee.  This Class A Certificate
does not purport to summarize  the Trust  Agreement and reference is hereby made
to the Trust  Agreement for information  with respect to the interests,  rights,
benefits, obligations, proceeds and duties


                                       D-1




evidenced  hereby and the rights,  duties and  obligations  of the Trustee  with
respect  hereto.  A copy of the Trust Agreement may be obtained from the Trustee
by written  request sent to the Corporate Trust Office.  Capitalized  terms used
but not  defined  herein  have  the  meanings  assigned  to  them  in the  Trust
Agreement.

     This  Class  A  Certificate  is  one of the  duly  authorized  Certificates
designated  as  "CorTS(R)  Class A  Certificates"  (herein  called  the "Class A
Certificate"  or "Class A  Certificates").  This Class A  Certificate  is issued
under and is  subject  to the  terms,  provisions  and  conditions  of the Trust
Agreement,  to which Trust  Agreement the Holder of this Class A Certificate  by
virtue of the acceptance  hereof assents and by which such Holder is bound.  The
assets of the Trust include the Term Assets and all proceeds of the Term Assets.
Additional  Term  Assets  may be  sold to the  Trustee  and  additional  Class A
Certificates may be authenticated and delivered from time to time as provided in
the Trust Agreement, which additional Class A Certificates shall rank pari passu
with all  other  Class A  Certificates  issued  in  accordance  with the  Series
Supplement.

     Under  the  Trust  Agreement,  there  shall  be  distributed  on the  dates
specified in the Trust Agreement (a "Distribution Date"), to the person in whose
name this Class A  Certificate  is  registered  at the close of  business on the
related  Record  Date,  such Class A  Certificateholder's  fractional  undivided
interest in the amount of  distributions of the Term Assets to be distributed to
Class A Certificateholders on such Distribution Date. Unless an Extension Period
is in effect,  the Term Assets will pay interest on January 1 and July 1 of each
year, except that the final payment of interest will be on January 1, 2027, with
the next interest  payment date  occurring on July 1, 2002. The principal of the
Term Assets is scheduled to be paid on January 1, 2027.

     The  distributions  in respect of this Class A  Certificate  are payable in
such coin or currency of the United  States of America as at the time of payment
is legal  tender for  payment of public  and  private  debts as set forth in the
Series Trust Agreement.

     The  Term  Assets  held by the  Trust  are  subject  to the  rights  of the
Warrantholders,  as  provided  for in the  Series  Supplement,  and each Class A
Certificateholder,  by  accepting  its Class A  Certificate,  acknowledges  such
rights and the possibility of an early redemption of the Class A Certificates in
accordance with the terms of the Series Supplement.

     It is the intent of the Depositor,  the Class A Certificateholders  and the
Class B Certificateholders  that the Trust will be classified as a grantor trust
under subpart E, Part I of subchapter J of the Internal Revenue Code of 1986, as
amended,  and failing  that,  as a  partnership  (other  than a publicly  traded
partnership  treated  as  a  corporation).  In  the  event  that  the  Trust  is
characterized by appropriate tax authorities as a partnership for federal income
tax purposes,  each  Certificateholder,  by its  acceptance of its  Certificate,
agrees to report its respective  share of the items of income,  deductions,  and
credits of the Trust on its  respective  returns  (making  such  elections as to
individual items as may be appropriate) in accordance with Treasury  Regulations
Section 1.761-2(b) (i.e., in a manner consistent with the exclusion of the Trust
from   partnership   tax   accounting).   In  mutual   consideration   for  each
Certificateholder's  purchase of a Certificate,  each such  Certificateholder is
deemed to agree not to delegate  (for a period of more than one year)  authority
to purchase, sell or exchange its Certificate to any person. Except as otherwise
required by appropriate taxing  authorities,  the Depositor and the Trustee,  by
executing the Trust Agreement, and each Class A Certificateholder, by acceptance
of a Class A Certificate, agrees to


                                       D-2




treat,  and to  take  no  action  inconsistent  with  such  intentions  and  the
provisions  of the  Trust  Agreement  shall  be  interpreted  to  further  these
intentions of the parties.

     Each Class A Certificateholder, by its acceptance of a Class A Certificate,
covenants and agrees that such Class A Certificateholder shall not, prior to the
date which is one year and one day after the termination of the Trust Agreement,
acquiesce,  petition or  otherwise  invoke or cause the  Depositor to invoke the
process of any court or governmental  authority for the purpose of commencing or
sustaining a case against the Depositor  under any federal or state  bankruptcy,
insolvency,  reorganization or similar law or appointing a receiver, liquidator,
assignee,  trustee,  custodian,  sequestrator  or other similar  official of the
Depositor or any substantial part of its property, or ordering the winding up or
liquidation of the affairs of the Depositor.

     The  Trust   Agreement   permits   the   amendment   thereof,   in  certain
circumstances,  without  the  consent  of the  Holders  of any  of the  Class  A
Certificates.

     Unless the certificate of authentication hereon shall have been executed by
an  authorized  officer  of the  Trustee  by  manual  signature,  this  Class  A
Certificate  shall not entitle the Holder  hereof to any benefit under the Trust
Agreement or be valid for any purpose.

     A copy of the Trust  Agreement  is  available  upon  request and all of its
terms and  conditions  are  hereby  incorporated  by  reference  and made a part
hereof.

     THIS CLASS A CERTIFICATE  SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS,  AND
THE  OBLIGATIONS,  RIGHTS  AND  REMEDIES  OF  THE  PARTIES  HEREUNDER  SHALL  BE
DETERMINED IN ACCORDANCE WITH SUCH LAWS.

                                    Article I

                              Exercise of Warrants

     Section I.1 Manner of  Exercise.  (a) This Call Warrant may be exercised by
the holder hereof (each, a "Warrantholder"), in whole or in part, on any Warrant
Exercise  Date,  set forth in the prior written  notice to the Warrant Agent and
the Trustee delivered at any time on or before the Business Day that is at least
fifteen (15) days before such Warrant  Exercise  Date, by surrender of this Call
Warrant to the Warrant  Agent at its office set forth in Section  VI.3 hereof no
later than  11:00  a.m.  (New York City  time) on such  Warrant  Exercise  Date;
provided that such 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 applicable  Warrant  Exercise  Purchase  Price, in a manner
such that funds are available to the Warrant Agent no later than 11:00 a.m. (New
York City time) on such Warrant  Exercise Date, and such holder shall  thereupon
be entitled to  delivery  of the Term  Assets  equal to $1,000 per Call  Warrant
purchased hereunder in accordance with this Article I; provided further that the
Warrantholder  may  not  exercise  this  Call  Warrant  at any  time  when  such
Warrantholder  is insolvent,  and in connection  therewith,  such  Warrantholder
shall  be  required  to  certify  that it is  solvent  at the  time of  exercise
settlement, by completing the Form of Subscription attached to this Call Warrant
and delivering such completed Form of Subscription to the Trustee on or prior to
the Warrant Exercise Date.

     (b) The Warrant Agent shall notify the Trustee  immediately upon receipt by
the  Warrant  Agent of a notice  by the  holder of this  Call  Warrant  and upon
receipt of payment of the applicable  Warrant Exercise  Purchase Price from such
holder  pursuant to clause (a) of this  Section  I.1.  The  Warrant  Agent shall
transfer each payment made by the holder  hereof  pursuant to clause (a) of this
Section I.1 to the  Trustee in  immediately  available  funds,  for  application
pursuant to the Trust  Agreement no later than 1:00 p.m. (New York City time) on
the applicable  Warrant  Exercise Date (and,  pending such transfer,  shall hold
each such  payment for the benefit of the holder  hereof in a  segregated  trust
account).

     (c) A  notice  by  the  holder  of a  Call  Warrant  does  not  impose  any
obligations on a holder of a Call Warrant in any way to pay any Warrant Exercise
Purchase Price.  If, by 11:00 a.m. (New York City time) on the Warrant  Exercise
Date,  the holder of the Call Warrant  being  exercised has not paid the Warrant
Exercise Purchase Price, then such notice shall automatically expire and none of
the holder of such Call  Warrant,  the Warrant  Agent and the Trustee shall have
any obligations  with respect to such notice by the holder of such Call Warrant.
The  expiration  of a notice by the holder of this Call Warrant  shall in no way
affect a holder of a Call Warrant's right to subsequently deliver a notice which
satisfies the terms of the Trust Agreement.

     (d) In the event of a  partial  redemption  of the Term  Assets by the Term
Assets  Issuer,  if the holders of the Call Warrants fail to exercise their Call
Warrants  with respect to all Term Assets  redeemed in such partial  redemption,
the number of outstanding  Warrants held by each Warrantholder  shall be reduced
proportionately  so that the amount of Term Assets  callable by the  exercise of
Call  Warrants  equals the amount of Term  Assets  remaining  in the Trust.  The
Warrant Agent shall make such  adjustments  to its records as shall be necessary
to  reflect  such  reductions  and  shall  notify  each  Warrantholder  of  such
adjustments.


                                       E-2




     Section I.2 Transfer of Term Assets.  (a) As soon as practicable after each
surrender  of this Call  Warrant,  in whole or in part,  and no later than 11:00
a.m. (New York City time) on the Warrant Exercise Date and upon  satisfaction of
all other requirements  described in this Call Warrant,  the Warrant Agent shall
instruct  the  Trustee  to cause the Term  Assets  represented  by the number of
Warrants being exercised  hereunder to be registered on the book-entry system of
the related  depositary in the registered name or names furnished by the holder,
and, in case such  exercise is in part only,  a new Call  Warrant of like tenor,
representing  the  remaining  outstanding  Warrants  of  the  holder,  shall  be
delivered by the Warrant Agent to the holder hereof. The Trustee shall cause the
delivery  of such  portion of the Term  Assets to the  holder or its  nominee no
later than 1:00 p.m.  (New York City time) on the  applicable  Warrant  Exercise
Date in accordance with Section 8(d) of the Trust Agreement.

     (b)  If any  Call  Warrant  is  exercised  in  connection  with  a  partial
redemption of Term Assets, the Trustee shall, to the extent possible, deliver to
the  exercising   Warrantholder,   Term  Assets  that  have  been  selected  for
redemption.

     Section I.3 Cancellation and Destruction of Call Warrant. All Call Warrants
surrendered  to the Warrant  Agent for the  purpose of exercise  (in whole or in
part)  pursuant to Section  I.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 shall be issued in lieu  thereof.  The Warrant Agent
shall destroy all cancelled Call Warrants.

     Section I.4 No Rights as Holder of Term Assets  Conferred by  WarrantsPrior
to the exercise hereof, this Call Warrant shall not entitle the holder hereof to
any of the rights of a holder of the Term Assets, including, without limitation,
the right to  receive  the  payment  of any  amount on or in respect of the Term
Assets or to enforce any of the covenants of the Trust Agreement.

                                   Article II

                            Restrictions on Transfer

     Section II.1  Restrictive  Legends.  Except as otherwise  permitted by this
Article II,  each Call  Warrant  (including  each Call  Warrant  issued upon the
transfer of any Call Warrant) shall be issued with a legend in substantially the
following form:

     "This Call Warrant has not been, and the Warrants  represented  hereby have
not been,  registered under the Securities Act of 1933, as amended,  and may not
be transferred,  sold or otherwise disposed of except while a registration under
such Act is in effect or pursuant to an exemption therefrom under such Act. This
Call  Warrant  and any Warrant  represented  hereby may be  transferred  only in
compliance  with the  conditions  specified  in this Call Warrant and may not be
transferred to Salomon Smith Barney Inc. or Structured Products Corp."

     Section II.2 Notice of Proposed Transfer; Opinions of Counsel. Prior to any
transfer of any Call  Warrant or portion  thereof,  the holder  hereof will give
five (5) Business Days (or such lesser period  acceptable to the Warrant  Agent)
prior written  notice to the Warrant Agent of such holder's  intention to effect
such transfer and to comply in all other  respects with this Section II.2.  Each
transfer of a portion of a Call Warrant must be for a whole number of


                                       E-3




Warrants.  Each such notice (a) shall describe the manner and  circumstances  of
the proposed  transfer in sufficient  detail to enable counsel for the holder to
render the opinions  referred to below, and (b) shall designate  counsel for the
holder  giving  such  notice.  The holder  giving such notice will submit a copy
thereof to the counsel  designated in such notice. If (A) in the opinion of such
counsel  for  the  holder  the  proposed   transfer  may  be  effected   without
registration of such Call Warrant under the Securities Act (such opinion stating
the basis for such  determination) and (B) such opinion is in form and substance
reasonably  satisfactory  to the  Depositor and the Warrant  Agent,  such holder
shall thereupon be entitled to transfer such Call Warrant in accordance with the
terms  of the  notice  delivered  by such  holder  to the  Warrant  Agent.  Each
instrument  representing  such Call Warrant or portion thereof issued upon or in
connection  with such transfer  shall bear the  restrictive  legend  required by
Section II.1, unless the Warrant Agent shall have received an opinion of counsel
reasonably  satisfactory to the Warrant Agent and the Depositor that such legend
is no longer required to ensure compliance with the Securities Act.

                                   Article III

                Registration and Transfer of Call Warrants, etc.

     Section III.1 Warrant  Register;  Ownership of Call  Warrants.  The Warrant
Agent will keep a register  in which the  Warrant  Agent  will  provide  for the
registration of Call Warrants and the registration of transfers of Call Warrants
representing  whole  numbers of Warrants.  The Trustee and the Warrant Agent may
treat the Person in whose name any Call 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.

     Section III.2 Transfer and Exchange of Call Warrants. Upon surrender of any
Call Warrant for  registration of transfer or for exchange to the Warrant Agent,
the Warrant  Agent shall  (subject to  compliance  with  Article II) execute and
deliver,  and cause the Trustee, on behalf of the Trust, to execute and deliver,
in exchange  therefor,  a new Call  Warrant of like tenor and  evidencing a like
whole  number of  Warrants,  in the name of such holder or as such holder  (upon
payment by such holder of any applicable  transfer taxes or government  charges)
may direct.

     Section  III.3  Replacement  of Call  Warrants.  Upon  receipt of  evidence
reasonably satisfactory to the Warrant Agent of the loss, theft,  destruction or
mutilation  of any Call  Warrant  and,  in the case of any such  loss,  theft or
destruction  of any Call  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 Call 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
Call Warrant of like tenor bearing a number not contemporaneously outstanding.

     Section  III.4  Execution  and  Delivery of Call  Warrants  by  Trustee.The
Trustee,  on behalf of the Trust,  hereby  agrees  (subject to  compliance  with
Article II) to execute and deliver such new Call  Warrants  issued in accordance
with  Section  I.2 or this  Article III as the  Warrant  Agent shall  request in
accordance herewith.

(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 holder of a Call  Warrant,  then the  Warrant  Agent or
registered   holder  of  any  Warrant  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.

association,  not  in  its  individual  capacity  but  solely  as  Trustee  (the
"Trustee"),  as supplemented by the CorTS(R) Supplement 2002-6,  dated as of May
31, 2002 (the "Series  Supplement" and, together with the Agreement,  the "Trust
Agreement"),  between the  Depositor  and the Trustee.  This Class B Certificate
does not purport to summarize  the Trust  Agreement and reference is hereby made
to the Trust  Agreement for information  with respect to the interests,  rights,
benefits,  obligations,  proceeds  and duties  evidenced  hereby and the rights,
duties and obligations of the Trustee with respect  hereto.  A copy of the Trust
Agreement  may be  obtained  from the  Trustee  by written  request  sent to the
Corporate Trust Office.  Capitalized  terms used but not defined herein have the
meanings assigned to them in the Trust Agreement.

     This  Class  B  Certificate  is  one of the  duly  authorized  Certificates
designated  as  "CorTS(R)  Class B  Certificates"  (herein  called  the "Class B
Certificate"  or "Class B  Certificates").  This Class B  Certificate  is issued
under and is  subject  to the  terms,  provisions  and  conditions  of the Trust
Agreement,  to which Trust  Agreement the Holder of this Class B Certificate  by
virtue of the acceptance  hereof assents and by which such Holder is bound.  The
assets of the Trust include the Term Assets and all proceeds of the Term Assets.
Additional  Term  Assets  may be  sold to the  Trustee  and  additional  Class B
Certificates may be authenticated and delivered from time to time as provided in
the Trust Agreement, which additional Class B Certificates shall rank pari passu
with all  other  Class B  Certificates  issued  in  accordance  with the  Series
Supplement.

     Under  the  Trust  Agreement,  there  shall  be  distributed  on the  dates
specified in the Trust Agreement (a "Distribution Date"), to the person in whose
name this Class B  Certificate  is  registered  at the close of  business on the
related  Record  Date,  such Class B  Certificateholder's  fractional  undivided
interest  in the  amount  of  interest  distributions  of the Term  Assets to be
distributed to Class B  Certificateholders  on such Distribution Date. Unless an
Extension  Period is in effect,  the Term Assets will pay  interest on January 1
and July 1 of each year,  except that the final  payment of interest  will be on
January 1, 2027, with the next interest  payment date occurring on July 1, 2002.
The Class B Certificate  has no interest in any principal of, or premium on, the
Term Assets.

     The  distributions  in respect of this Class B  Certificate  are payable in
such coin or currency of the United  States of America as at the time of payment
is legal  tender for  payment of public  and  private  debts as set forth in the
Series Trust Agreement.

     The  Term   Assets  held  by  the  Trust  are  subject  to  rights  of  the
Warrantholders,  as  provided  for in the  Series  Supplement,  and each Class B
Certificateholder,  by  accepting  its Class B  Certificate,  acknowledges  such
rights and the possibility of an early redemption of the Class B Certificates in
accordance with the terms of the Series Supplement.


                                       F-2




     It is the intent of the Depositor,  the Class A Certificateholders  and the
Class B Certificateholders  that the Trust will be classified as a grantor trust
under subpart E, Part I of subchapter J of the Internal Revenue Code of 1986, as
amended,  and failing  that,  as a  partnership  (other  than a publicly  traded
partnership  treated  as  a  corporation).  In  the  event  that  the  Trust  is
characterized by appropriate tax authorities as a partnership for federal income
tax purposes,  each  Certificateholder,  by its  acceptance of its  Certificate,
agrees to report its respective  share of the items of income,  deductions,  and
credits of the Trust on its  respective  returns  (making  such  elections as to
individual items as may be appropriate) in accordance with Treasury  Regulations
Section 1.761-2(b) (i.e., in a manner consistent with the exclusion of the Trust
from   partnership   tax   accounting).   In  mutual   consideration   for  each
Certificateholder's  purchase of a Certificate,  each such  Certificateholder is
deemed to agree not to delegate  (for a period of more than one year)  authority
to purchase, sell or exchange its Certificate to any person. Except as otherwise
required by appropriate taxing  authorities,  the Depositor and the Trustee,  by
executing the Trust Agreement, and each Class B Certificateholder, by acceptance
of a Class B Certificate,  agrees to treat,  and to take no action  inconsistent
with  such  intentions  and the  provisions  of the  Trust  Agreement  shall  be
interpreted to further these intentions of the parties.

     Each Class B Certificateholder, by its acceptance of a Class B Certificate,
covenants and agrees that such Class B Certificateholder shall not, prior to the
date which is one year and one day after the termination of the Trust Agreement,
acquiesce,  petition or  otherwise  invoke or cause the  Depositor to invoke the
process of any court or governmental  authority for the purpose of commencing or
sustaining a case against the Depositor  under any federal or state  bankruptcy,
insolvency,  reorganization or similar law or appointing a receiver, liquidator,
assignee,  trustee,  custodian,  sequestrator  or other similar  official of the
Depositor or any substantial part of its property, or ordering the winding up or
liquidation of the affairs of the Depositor.

     The  Trust   Agreement   permits   the   amendment   thereof,   in  certain
circumstances,  without  the  consent  of the  Holders  of any  of the  Class  B
Certificates.

     Unless the certificate of authentication hereon shall have been executed by
an  authorized  officer  of the  Trustee  by  manual  signature,  this  Class  B
Certificate  shall not entitle the Holder  hereof to any benefit under the Trust
Agreement or be valid for any purpose.

     A copy of the Trust  Agreement  is  available  upon  request and all of its
terms and  conditions  are  hereby  incorporated  by  reference  and made a part
hereof.

     THIS CLASS B CERTIFICATE  SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF
THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS,  AND
THE  OBLIGATIONS,  RIGHTS  AND  REMEDIES  OF  THE  PARTIES  HEREUNDER  SHALL  BE
DETERMINED IN ACCORDANCE WITH SUCH LAWS.
