created hereby shall be known as the "Corporate Backed Trust Certificates,

interests therein shall be known as "Corporate Backed Trust Certificates, Series
2001-18." The Certificates shall consist of the Class A-1 Certificates and the
Class A-2 Certificates (together, the "Certificates"). The Trust is also issuing
call warrants with respect to the Certificates (the "Call Warrants").

                  (a) The Certificates shall be held through the Depository in
book-entry form and shall be substantially in the forms attached hereto as
Exhibits A-1 and A-2. The Class A-1 Certificates shall be issued in
denominations of $25. The Class A-2 Certificates shall be issued in minimum
notional denominations of $500,000 and in integral multiples of $1,000 in excess
thereof. One Class A-2 Certificate may be issued in a notional amount that is
not an integral multiple of the applicable minimum denomination. Except as
provided in the Standard Terms and in paragraph (d) in this Section, the Trust
shall not issue additional Certificates or incur any indebtedness.

                  (b) The Class A-1 Certificates have an initial aggregate
certificate principal amount ("Certificate Principal Amount") of $25,000,000.
The Class A-2 Certificates are interest-only Certificates, and have a notional
principal amount equal to the Certificate Principal Amount of the Class A-1
Certificates.

                  (c) The holders of the Class A-1 Certificates will be entitled
to receive on each Distribution Date the interest, if any, received on the
Underlying Securities, to the extent necessary to pay interest at a rate of
7.375% per annum on the outstanding Certificate Principal Amount of the Class
A-1 Certificates. The holders of the Class A-2 Certificates will be entitled to
receive on each Distribution Date the interest, if any, received on the

                                       8
<PAGE>

Underlying Securities, to the extent necessary to pay interest at a rate of
0.815% per annum on the outstanding notional principal amount of the Class A-2
Certificates. On February 1, 2001, the Trustee will pay to the Depositor the
amount of interest accrued on the Underlying Securities from August 1, 2000 to
but not including the Closing Date. If the Depositor is not paid such amount on
such date, it will have a claim for such amount. In satisfaction of that claim
the Depositor will receive its pro rata share, based on the ratio the amount
owed to the Depositor bears to all amounts owed on the Certificates in respect
of accrued interest, of any proceeds recovered in respect of the Underlying
Securities.

                  (d) The Depositor may sell to the Trustee additional
Underlying Securities on any date hereafter upon at least 3 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
Underlying Securities will not materially increase the likelihood that the Trust
would fail to qualify as a grantor trust under the Code. Upon such sale to the
Trustee, the Trustee shall deposit such additional Underlying Securities in the
Certificate Account, and shall authenticate and deliver to the Depositor, on its
order, Class A-1 Certificates and Class A-2 Certificates in the same proportion
that the original Class A-1 Certificates and Class A-2 Certificates bear to the
Underlying Securities. Any such additional Certificates authenticated and
delivered shall have the same terms and rank pari passu with the corresponding
classes of Certificates previously issued in accordance with this Series
Supplement.

                  (e) As a condition precedent for transferring the Call
Warrants, the prospective transferee shall be required to deliver to the Trustee
and the Depositor an executed copy of the Investment Letter in the form set
forth as Exhibit C hereto.

                  Section 4. Trust Certificates. The Trustee hereby acknowledges
receipt, on or prior to the Closing Date, of:

                  (i)      the Underlying Securities set forth on the Underlying
                           Securities Schedule; and

                  (ii)     all documents required to be delivered to the Trustee
                           pursuant to Section 2.01 of the Standard Terms.

                  Section 5. Distributions. (a) On each applicable Distribution
Date, the Trustee shall apply Available Funds in the Certificate Account as
follows (subject to Section 5(b) below) in the following order of priority:

                  (i)      the Trustee will pay the interest portion of
                           Available Funds:

                                    (a) first, to the Trustee, as reimbursement
                                    for any Extraordinary Trust Expenses
                                    incurred by the Trustee in accordance with
                                    Section 6(b) below and approved by 100% of
                                    the Certificateholders; and

                                       9
<PAGE>

                                    (b) second, to the holders of the Class A-1
                                    Certificates and the holders of the Class
                                    A-2 Certificates, interest accrued and
                                    unpaid on each such Class pro rata in
                                    proportion to their entitlements thereto
                                    (subject to Section 5(b) below); and

                                    (c) third, any remainder to the Depositor.

                  (ii)     the Trustee will pay the principal portion of
                           Available Funds:

                                    (a) first, to the Trustee, as reimbursement
                                    for any remaining Extraordinary Trust
                                    Expenses incurred by the Trustee in
                                    accordance with Section 6(b) below and
                                    approved by 100% of the Certificateholders;
                                    and

                                    (b) second, to the holders of the Class A-1
                                    Certificates, the outstanding principal
                                    amount of the Class A-1 Certificates.

                  (b) Distributions of interest on the Certificates may be
deferred as a result of the deferral of payment on the Underlying Securities.
Distributions on the Underlying Securities may be deferred pursuant to the
Underlying Securities Trust Agreement for up to ten consecutive semiannual
interest periods (each a "Deferral Period") provided that no Deferral Period may
extend beyond the Final Scheduled Distribution Date. During any Deferral Period,
interest on the Underlying Securities and consequently, the Certificates, will
continue to accrue at the applicable rate per annum compounded semi-annually.
Interest on deferred and compounded interest on the Certificates will be owing
only to the extent that such interest is actually received by the Trustee on the
Underlying Securities.

                  (c) Notwithstanding any other provision hereof, amounts
recovered in respect of the Underlying Securities prior to the Final Scheduled
Distribution Date following (i) an acceleration of the date of maturity of the
Underlying Securities, (ii) the redemption or other prepayment of the Underlying
Securities by the Underlying Securities Issuer or (iii) the sale of the
Underlying Securities by the Trust, shall be distributed pursuant to the
priorities specified in Section 5(d) hereof.

                  (d) Notwithstanding the foregoing, in the event that the
Underlying Securities are redeemed or prepaid in whole or in part for any reason
other than at their maturity (for instance, if the Underlying Securities are
paid early in connection with a liquidation of The Southern Company or in
connection with certain adverse tax events), Available Funds will be allocated
in the following order of priority: (1) to the Trustee, reimbursement for any
Extraordinary Expenses incurred by the Trustee in accordance with the Trust
Agreement pursuant to instructions of not less than 100% of the
Certificateholders, (2) to the holders of the Class A-1 Certificates, an amount
equal to the outstanding principal amount thereof plus accrued and unpaid
interest thereon, (3) to the holders of the Class A-2 Certificates, the present

                                       10
<PAGE>

value of all amounts that would otherwise have been payable on the Class A-2
Certificates for the period from the date of such redemption or prepayment to
the Final Scheduled Distribution Date using a discount rate of 7.375% per annum,
assuming no delinquencies, deferrals, redemptions or prepayments on the
Underlying Securities and (4) any remainder shall be allocated to the holders of
the Class A-1 Certificates and the Class A-2 Certificates in proportion to the
ratio of the Class A-1 Allocation to the Class A-2 Allocation. If the Underlying
Securities are redeemed, prepaid or liquidated in whole or in part due to the
occurrence of an Event of Default, Available Funds will be allocated to the
holders of the Class A-1 Certificates and the holders of the Class A-2
Certificates in proportion to the ratio of the Class A-1 Allocation to the Class
A-2 Allocation.

                  (e) Notwithstanding any other provision hereof, in the event
of the occurrence of an Event of Default, the Trustee shall proceed against the
Underlying Securities Issuer on behalf of the Certificateholders to enforce the
Underlying Securities or otherwise to protect the interests of the
Certificateholders, provided that, holders of the Certificates representing a
majority of the Voting Rights on the Certificates will be entitled to direct the
Trustee in any such proceeding or direct the Trustee to sell the Underlying
Securities. If the Trustee is directed to sell the Underlying Securities, the
Trustee shall solicit bids for the sale of the Underlying Securities with
settlement thereof on or before the third (3rd) Business Day after such sale
from three leading dealers in the relevant market. Any of the following dealers
(or their successors) shall be deemed to qualify as leading dealers: (1) Credit
Suisse First Boston Corporation, (2) Goldman, Sachs & Co., (3) Lehman Brothers
Inc., (4) Merrill Lynch, Pierce, Fenner & Smith Incorporated, (5) UBS Warburg
LLC and (6) Salomon Smith Barney Inc. The Trustee shall not be responsible for
the failure to obtain a bid so long as it has made reasonable efforts to obtain
bids. If a bid for the sale of the Underlying Securities has been accepted by
the Trustee but the sale has failed to settle on the proposed settlement date,
the Trustee shall request new bids from such leading dealers. In the event of
such sale or of an acceleration and a corresponding payment on the Underlying
Securities, the Trustee shall distribute the proceeds to the Certificateholders
no later than two Business Days after the receipt of immediately available funds
in accordance with Section 5(c) hereof.

                  (f) In the event that the Trustee receives non-cash property
in respect of the Underlying Securities as a result of a payment default on the
Underlying Securities (including from the sale thereof), the Trustee will
promptly give notice 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 property, the Trustee will allocate
and distribute such property to the holders of Class A-1 Certificates and Class
A-2 Certificates then outstanding and unpaid, (after deducting the costs
incurred in connection therewith) in accordance with Section 5 (a) hereof.
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 Certificateholders. In-kind distribution of such

                                       11
<PAGE>

property to Certificateholders will be deemed to reduce the principal amount of
Certificates on a dollar-for-dollar basis.

                  (g) Subject to Section 9(f) hereof, to the extent Available
Funds are insufficient to make any required distributions due to any class of
Certificates on any Distribution Date, any shortfall will be carried over and
will be distributed on the next Distribution Date (or date referred to in
Section 5(h) hereof) on which sufficient funds are available on the Available
Funds to pay such shortfall.

                  (h) If a payment with respect to the Underlying Securities is
made to the Trustee after the payment date of the Underlying Securities on which
such payment was due, then the Trustee will distribute any such amounts received
on the next occurring Business Day (a "Special Distribution Date") as if the
funds had constituted Available Funds on the Distribution Date immediately
preceding such Special Distribution Date; provided, however, that the Record
Date for such Special Distribution Date shall be five Business Days prior to the
day on which the related payment was received from the Underlying Securities
Trustee.

                  (i) In the event that the Junior Subordinated Notes are
distributed to the Trust in exchange for the Underlying Securities upon the
occurrence of a Special Event Redemption, such distribution will not cause the
Certificates to be redeemed. The Trust will hold the Junior Subordinated Notes
for the benefit of the Certificateholders in accordance with the terms of the
Trust Agreement.

                  Section 6. Trustee's Fees. (a) As compensation for its
services hereunder, the Trustee shall be entitled to the Trustee Fee. The
Trustee Fee shall be paid by the Depositor and not from Trust Property. The
Trustee shall bear all Ordinary Expenses. Failure by the Depositor to pay such
amount shall not entitle the Trustee to any payment or reimbursement from the
Trust, nor shall such failure release the Trustee from the duties it is required
to perform under the Trust Agreement.

                  (b) Extraordinary Expenses shall not be paid out of the Trust
Property unless all the Certificateholders of each of Class A-1 and Class A-2
Certificates then outstanding have voted to require the Trustee to incur such
Extraordinary Expenses. The Trustee may incur other Extraordinary Expenses if
any lesser percentage of the Certificateholders requesting such action pursuant
hereto reimburse the Trustee for the cost thereof from their own funds in
advance. If Extraordinary Expenses are not approved unanimously as set forth in
the first sentence of this Section 6(b), such Extraordinary Expenses shall not
be an obligation of the Trust, and the Trustee shall not file any claim against
the Trust therefor notwithstanding failure of Certificateholders to reimburse
the Trustee.

                  Section 7. Optional Exchange; Optional Call.

                  (a) (i) On each Distribution Date (or, if the Depositor or an
Affiliate of the Depositor holds all of the Certificates and the Call Warrants,
on any other date) the Depositor or any Affiliate of the Depositor, if it is

                                       12
<PAGE>

then the holder of Class A-1 Certificates of a certain principal amount and
Class A-2 Certificates of a certain notional principal amount which represent a
like percentage of all Class A-2 Certificates and (except to the extent such
Certificates were acquired through the exercise of Call Warrants) the holder of
Call Warrants related to the Class A-1 Certificates and Call Warrants related to
the Class A-2 Certificates which, in each case, represent a like percentage of
all such outstanding Call Warrants may tender such Class A-1 Certificates and
Class A-2 Certificates and such Call Warrants to the Trustee on such date and
receive a distribution of Underlying Securities representing a like percentage
of the Underlying Securities to the percentages of the Class A-1 Certificates,
Class A-2 Certificates and the related Call Warrants being tendered by the
Depositor or Affiliate to the Trustee; provided, however, that any right to
exchange shall be exercisable only (x) to the extent that the Depositor provides
upon the Trustee's request an opinion of counsel that such exchange would not
affect the characterization of the Trust as a "grantor trust" for federal income
tax purposes and (y) to the extent permitted under Section 7(a)(iv) hereof.

                  (i) Any such Affiliate of the Depositor must provide notice to
the Trustee (an "Exchange Request") no less than 5 days (or such shorter period
acceptable to the Trustee) but not more than 30 days prior to an Optional
Exchange Date that it requests an Optional Exchange of Certificates on such
Optional Exchange Date.

                  (ii) The Trustee shall not be obligated to determine whether
an Optional Exchange complies with the applicable provisions for exemption under
Rule 3a-7 of the Investment Company Act of 1940, as amended, or the rules or
regulations promulgated thereunder.

                  (iii) Any such Optional Exchange by any Affiliate of the
Depositor, will be subject to the following restrictions: (a) certification to
the Trustee that any Certificates to be exchanged have been held for a minimum
of six months and (b) each Optional Exchange is limited in amount to a maximum
of 5% (except for Certificates acquired by the Underwriter but never distributed
to investors, in which case 25%) of the then outstanding principal amount of the
Certificates; provided, however, that such restrictions shall not apply to the
exchange of Certificates that were acquired pursuant to Section 7(b).

                  (iv) The provisions of Section 4.07 of the Standard Terms
shall not apply to an Optional Exchange pursuant to this Section. This Section 7
shall not provide the Depositor with a lien against, an interest in or a right
to specific performance with respect to the Underlying Securities.

                  (b) (i) Concurrently with the execution of this Series
Supplement, the Trustee, on behalf of the Trust, shall execute the Warrant Agent
Agreement and the Call Warrants, dated as of the date hereof and substantially
in the form of Exhibit B hereto, initially evidencing all of the Call Warrants.
The Trustee shall perform the Trust's obligations under the Warrant Agent
Agreement and the Call Warrants in accordance with their respective terms. On
any Call Date, the Certificates may be called at the applicable Call Price, in

                                       13
<PAGE>

whole or in part, by the Warrant Holder, upon payment of such Call Price on or
prior to such Call Date.

                  (i) The Warrant Holder may provide notice to the Trustee (a
"Call Request") no less than 5 Business Days prior to any Call Date, that it is
exercising its Call Warrants with respect to the Certificates on such Call Date.
The Call Request shall be deemed to be notice of an Optional Exchange pursuant
to Section 7(a) hereof of the Certificates to be acquired on the Call Date. Upon
request of the Trustee, the Warrant Holder shall deliver the opinion specified
in Section 7(a)(i)(x) above as a condition to any Optional Call.

                  (ii) Upon receipt of a Call Request, the Trustee shall provide
a conditional call notice to the Depository not less than 3 Business Days prior
to the applicable Call Date.

                  (iii) As a condition to any Optional Call, an opinion of
counsel to the Warrant Holder shall be delivered to the Rating Agencies, in form
satisfactory to the Rating Agencies, indicating that payment of the Call Price
shall not be recoverable as a preferential transfer or fraudulent conveyance
under the United States Bankruptcy Code. Such opinion may contain customary
assumptions and qualifications. In addition, the Warrant Holder shall provide a
certificate of solvency to the Trustee.

                  (iv) Deliveries of the Certificates to the Warrant Holder (the
"Purchaser") will only be made against payment by the Purchaser of the Call
Price in immediately available funds. Such payment must occur no later than
10:00 a.m. New York City time on the Call Date. In the event that the Purchaser
fails to make such payment by such time (a "Purchase Default"), the sale shall
be voided and the Optional Call will be deemed not to be effective with respect
to such Distribution Date, and the Certificates and the Call Warrants shall
continue to remain outstanding. Subject to receipt of the Call Price as
aforesaid, the Trustee shall pay the Call Price to the Certificateholders on the
Call Date in accordance with the definition of "Call Price". The Call Price in
respect of partial calls shall be allocated to the Certificateholders within
each Class pro rata to the extent of their entitlements thereto.

                  (v) The Trustee shall not consent to any amendment or
modification of this Agreement (including the Standard Terms) which would alter
the timing or amount of any payment of the Call Price without the prior written
consent of 100% of the Warrant Holders.

                  (vi) The Trustee shall not be obligated to determine whether
an Optional Call complies with the applicable provisions for exemption under
Rule 3a-7 of the Investment Company Act of 1940, as amended, or the rules or
regulations promulgated thereunder.

                                       14
<PAGE>

                  (vii) This Section 7 shall not provide the Warrant Holder with
a lien against, an interest in or a right to specific performance with respect
to the Underlying Securities.

                  (viii) The Warrant Holder shall initially be the Depositor.

                  Section 8. Events of Default.

                  Within 30 days of the occurrence of an Event of Default in
respect of the Certificates, the Trustee will give notice to the
Certificateholders, transmitted by mail, of all such uncured or unwaived Events
of Default known to it. However, except in the case of an Event of Default
relating to the payment of principal of or interest on any of the Underlying
Securities, the Trustee will be protected in withholding such notice if in good
faith it determines that the withholding of such notice is in the interest of
the Certificateholders.

                  Section 9. Miscellaneous.

                  The provisions of Section 4.04, Advances, of the Standard
Terms shall not apply to the Series 2001-18 Certificates.

                  The provisions of Section 4.07, Optional Exchange, of the
Standard Terms shall not apply to the Series 2001-18 Certificates.

                  The Trustee shall simultaneously forward reports to
Certificateholders pursuant to Section 4.03 of the Standard Terms and to the New
York Stock Exchange.

                  Except as expressly provided herein, the Certificateholders
shall not be entitled to terminate the Trust or cause the sale or other
disposition of the Underlying Securities.

                  The provisions of Section 3.07(d) of the Standard Terms shall
not apply to the Series 2001-18 Certificates.

                  If the Trustee has not received payment with respect to a
Collection Period on the Underlying Securities on or prior to the related
Distribution Date, such distribution will be made promptly upon receipt of such
payment. No additional amounts shall accrue on the Certificates or be owed to
Certificateholders as a result of such delay; provided, however, that any
additional interest owed and paid by the Underlying Securities Issuer as a
result of such delay shall be paid to the Certificateholders, pro rata in
proportion to their respective entitlements to interest.

                  The outstanding principal balance of the Certificates shall
not be reduced by the amount of any Realized Losses (as defined in the Standard
Terms).

                  The Trust may not engage in any business or activities other
than in connection with, or relating to, the holding, protecting and preserving
of the Trust Property and the issuance of the Certificates, and other than those

                                       15
<PAGE>

required or authorized by the Trust Agreement or incidental and necessary to
accomplish such activities. The Trust may not issue or sell any certificates or
other obligations other than the Certificates or otherwise incur, assume or
guarantee any indebtedness for money borrowed.

                  Notwithstanding anything in the Trust Agreement to the
contrary, the Trustee may be removed upon 60 days prior written notice delivered
by the holders of Class A-1 and Class A-2 Certificates representing the Required
Percentage-Removal.

                  In the event that the Internal Revenue Service challenges the
characterization of the Trust as a grantor trust, the Trustee shall then file
such forms as the Depositor may specify to establish the Trust's election
pursuant to Section 761 of the Code to exclude the Trust from the application of
Subchapter K of the Code and is hereby empowered to execute such forms on behalf
of the Certificateholders.

                  Notwithstanding anything in the Standard Terms to the
contrary, the Trustee, upon written direction by the Depositor, will execute the
Certificates.

                  In relation to Section 7.01(f) of the Standard Terms, any
periodic reports filed by the Trustee pursuant to the Securities and Exchange
Act of 1934, as amended, and the rules and regulations promulgated thereunder,
in accordance with the customary practices of the Depositor, need not contain
any independent reports.

                  Notwithstanding anything in the Trust Agreement to the
contrary, the Trustee will have no recourse to the Underlying Securities.

                  The Trust will not merge or consolidate with any other entity
without confirmation from each Rating Agency that such merger or consolidation
will not result in the qualification, reduction or withdrawal of its
then-current rating on the Certificates.

                  Notices. All directions, demands and notices hereunder or
under the Standard Terms shall be in writing and shall be delivered as set forth

                  Section 12. Termination of the Trust. The Trust shall
terminate upon the earliest to occur of (i) the payment in full at maturity or
sale by the Trust after a payment default on or an acceleration or other early

                                       17

payment of the Underlying Securities and the distribution in full of all amounts
due to the Class A-1 and Class A-2 Certificateholders; (ii) the Final Scheduled
Distribution Date; (iii) the expiration of 21 years from the death of the last
survivor of the descendants of Joseph P. Kennedy, the late Ambassador of the
United States to the Court of St. James, living on the date hereof and (iv) all
of the outstanding Certificates are exchanged for all of the Underlying
Securities in accordance with Section 7(a) hereof.

                  Section 13. Sale of Underlying Securities. In the event of a
sale of the Underlying Securities pursuant to Section 5(e) hereof, the
Liquidation Proceeds, if any, shall be deposited into the Certificate Account
for distribution to the Class A-1 and Class A-2 Certificateholders. The Trustee
shall only deliver the Underlying Securities to the purchaser of such Underlying
Securities against payment in same day funds deposited into the Certificate
Account.

                  Section 14. Amendments. Notwithstanding anything in the Trust
Agreement to the contrary, in addition to the other restrictions on modification
and amendment contained therein, the Trustee shall not enter into any amendment
or modification of the Trust Agreement which would adversely affect in any
material respect the interests of the holders of any class of Certificates
without the consent of the holders of 100% of such class of Certificates;
provided, however, that no such amendment or modification will be permitted
which would alter the status of the Trust as a grantor trust for federal income
tax purposes. Further, no amendment shall be permitted which would adversely
affect in any material respect the interests of any class of Certificateholders
without confirmation by each Rating Agency that such amendment will not result
in a downgrading or withdrawal of its rating of such Certificates.

                  Section 15. Voting of Underlying Securities, Modification of
Underlying Securities Trust Agreement. The Trustee, as holder of the Underlying
Securities, has the right to vote and give consents and waivers in respect of
the Underlying Securities as permitted by the Depository and except as otherwise
limited by the Trust Agreement. In the event that the Trustee receives a request
from the Depository, the Underlying Securities Trustee or the Underlying
Securities Issuer for its consent to any amendment, modification or waiver of
the Underlying Securities, the Underlying Securities Trust Agreement or any
other document thereunder or relating thereto, or receives any other
solicitation for any action with respect to the Underlying Securities, the
Trustee shall mail a notice of such proposed amendment, modification, waiver or
solicitation to each Certificateholder of record as of such date. The Trustee
shall request instructions from the Certificateholders as to whether or not to
consent to or vote to accept such amendment, modification, waiver or
solicitation. The Trustee shall consent or vote, or refrain from consenting or
voting, in the same proportion (based on the relative outstanding principal
balances of the Certificates) as the Class A-1 Certificates of the Trust were
actually voted or not voted by the Certificateholders thereof as of a date
determined by the Trustee prior to the date on which such consent or vote is
required; provided, however, that, notwithstanding anything in the Trust
Agreement to the contrary, the Trustee shall at no time vote on or consent to
any matter (i) unless such vote or consent would not (based on an opinion of

                                       18
<PAGE>

counsel) alter the status of the Trust as a grantor trust for federal income tax
purposes or result in the imposition of tax upon the Certificateholders, (ii)
which would alter the timing or amount of any payment on the Underlying
Securities, including, without limitation, any demand to accelerate the
Underlying Securities, except in the event of a default under the Underlying
Securities or an event which with the passage of time would become an event of
default under the Underlying Securities and with the unanimous consent of all
outstanding Class A-1 Certificateholders and the Class A-2 Certificateholders,
or (iii) which would result in the exchange or substitution of any of the
outstanding Underlying Securities pursuant to a plan for the refunding or
refinancing of such Underlying Securities except in the event of a default under
the Underlying Securities Trust Agreement and only with the consent of
Certificateholders representing 100% of the Class A-2 Certificates and 100% of
the Class A-1 Certificates. The Trustee shall have no liability for any failure
to act resulting from Certificateholders' late return of, or failure to return,
directions requested by the Trustee from the Certificateholders.

                  In the event that an offer is made by the Underlying
Securities Issuer to issue new obligations in exchange and substitution for any
of the Underlying Securities, pursuant to a plan for the refunding or
refinancing of the outstanding Underlying Securities or any other offer is made
for the Underlying Securities, the Trustee shall notify the Class A-1 and Class
A-2 Certificateholders of such offer promptly. The Trustee must reject any such
offer unless the Trustee is directed by the affirmative vote of the holders of
100% of the Class A-1 and Class A-2 Certificates to accept such offer and the
Trustee has received the tax opinion described above. If pursuant to the
preceding sentence, the Trustee accepts any such offer, the Trustee shall
promptly notify the Rating Agencies.

                  If an event of default under the Underlying Securities Trust
Agreement occurs and is continuing, and if directed by a majority of the
outstanding Class A-1 and Class A-2 Certificateholders, the Trustee shall vote
the Underlying Securities in favor of directing, or take such other action as
may be appropriate to direct, the Underlying Securities Trustee to declare the
unpaid principal amount of the Underlying Securities and any accrued and unpaid
interest thereon to be due and payable.

                            Exercise of Call Warrants

Section 1.1 Manner of Exercise. (a) This Call Warrant may be exercised by the
holder hereof (each, a "Warrant Holder"), in whole or in part, on any Call Date,
set forth in a written notice delivered to the Warrant Agent and the Trustee at
any time on or before the Business Day that is at least 5 Business Days before
such Call Date, by surrender of this Call Warrant to the Warrant Agent at its
office set forth in Section 6.3 hereof no later than 10:00 a.m. (New York City
time) on such Call 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 Call Price, in
a manner such that funds are available to the Warrant Agent no later than 10:00
a.m. (New York City time) on such Call Date, and such holder shall thereupon be
entitled to delivery of the Class A-1 Certificates in a Certificate Principal
Amount equal to $[25] per Call Warrant and Class A-2 Certificates in a notional
principal amount equal to $[25] per Call Warrant (if exercised in whole);
provided further that the Warrant Holder may not exercise this Call Warrant at
any time when such Warrant Holder is insolvent, and in connection therewith,
such Warrant Holder 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 Call Date and deliver to the Trustee a form reasonably
satisfactory to the Trustee of the opinion and the solvency certificate required
pursuant to Section 7(b)(iv) of the Series Supplement. Such notice of the
exercise of a Call Warrant shall be deemed to be notice of an Optional Exchange
pursuant to Section 7(a) of the Series Supplement.

(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 Call Price from such holder pursuant to clause (a) of
this Section 1.1. The Warrant Agent shall transfer each payment made by the
holder hereof pursuant to clause (a) of this Section 1.1 to the Trustee in
immediately available funds, for application pursuant to the Trust Agreement on
the applicable Call 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 Call Price. If, by 10:00 a.m.
(New York City time) on the Call Date, the holder of the Call Warrant being
exercised has not paid the Call 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.

Section 1.2 Transfer of Certificates. As soon as practicable after each
surrender of this Call Warrant, in whole or in part on the Call Date and upon
satisfaction of all other requirements described in this Call Warrant, the

                                      B-2
<PAGE>

Warrant Agent shall instruct the Trustee to effect an exchange of the portion of
the Certificates called for Underlying Securities pursuant to Section 7(a) of
the Series Supplement, and, in case such exercise is in part only, a new Call
Warrant of like tenor, representing the remaining outstanding Call Warrants of
the holder, shall be delivered by the Warrant Agent to the holder hereof.

Section 1.3 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 1.1 and actually exercised, or for the purpose of
transfer or exchange pursuant to Article III, shall be cancelled by the Warrant
Agent, and no Call Warrant shall be issued in lieu thereof. The Warrant Agent
shall destroy all cancelled Call Warrants.

Section 1.4 No Rights as Holder of Certificates Conferred by Call Warrants.
Prior to the exercise hereof, this Call Warrant shall not entitle the holder
hereof to any of the rights of a holder of the Certificates, including, without
limitation, the right to receive the payment of any amount on or in respect of
the Certificates or to enforce any of the covenants of the Trust Agreement.

                                   ARTICLE II

                            Restrictions on Transfer

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 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 represented
hereby may be transferred only in compliance with the conditions specified in
this Call Warrant."

Section 2.2 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.

Section 3.1 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 Call Warrants. The Trustee and the Warrant Agent may treat the
Person in whose name any Call Warrant is registered on such register so the
owner thereof for all purposes, and the Trustee and the Warrant Agent shall not
be affected by any notice to the contrary.

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,

exchange therefor, a new Call Warrant of like tenor and evidencing a like whole
number of Call 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.

satisfactory to the Warrant Agent of the loss, theft, destruction or mutilation

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 3.4 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 1.2
or this Article III as the Warrant Agent shall request in accordance herewith.

of any state.

                  The Purchaser understands that the Call Warrants have not been

sky laws of any state, and that (i) if it decides to resell, pledge or otherwise
transfer any Call Warrant, such Call Warrant may be resold, pledged or
transferred without registration only to an entity that has delivered to the
Depositor and the Trustee a certification that it is a Qualified Institutional
Buyer that purchases (1) for its own account or (2) for the account of such a
Qualified Institutional Buyer, that is, in either case, aware that the resale,
pledge or transfer is being made in reliance on said Rule 144A and (ii) it will,
and each subsequent holder will be required to, notify any purchaser of any Call
Warrant from it of the resale restrictions referred to in clause (i) above.

                  The Purchaser understands that each of the Call Warrants will
bear a legend to the following effect, unless otherwise agreed by the Depositor
and the Trustee:

                  "THIS CALL WARRANT HAS 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
                  REPRESENTED HEREBY MAY BE TRANSFERRED ONLY IN COMPLIANCE WITH
                  THE CONDITIONS SPECIFIED IN THIS CALL WARRANT."

                  The Purchaser understands that no subsequent transfer of the
Call Warrants is permitted unless it causes its proposed transferee to provide
to the Depositor and the Initial Warrant Holder a letter substantially in the
form of Exhibit C to the Series Supplement, as applicable, or such other written
statement as the Depositor shall prescribe.

                  The Purchaser agrees that if at some time in the future it
wishes to transfer or exchange any of the Call Warrants, it will not transfer or
exchange any of the Call Warrants unless such transfer or exchange is in
accordance with Section 5.04 of the Trust Agreement. The Purchaser understands

         that meets applicable Federal Communications Commission ("FCC")
         specifications. NCTC will, and will require each Participating Member
         to, use its best efforts to maintain and transmit a video and audio
         signal of each Service which is equivalent to the quality of the signal
         as transmitted by Network, and which at a minimum meets the
         specifications of the FCC.

     d.  If Network changes its means of delivering any Service after the
         Commencement Date, it will give NCTC as much notice of the change as is
         reasonably practicable and if, as a result of the change, any
         Participating Member will incur material out-of-pocket costs to
         continue to receive the Service at any Participating Member (each an

         (i) lend to NCTC, for each Affected Participating Member, the equipment
         necessary for the Affected Participating Member's continued receipt of
         the Service; (ii) reimburse NCTC, who in turn will reimburse the
         applicable Participating Member Owner, for the Participating Member

         distribution capacity contained within the bandwidth of each Service,
         and audio subcarriers, including without limitation the vertical
         blanking interval (VBI). Participating Members will pass all portions
         of each Service through to all respective Service Subscribers,
         including those that are directly related to or enhance the Service,
         but only to the extent that such use does not produce separate revenue
         (i.e., Network does not charge a fee for such use).

     g.  Network has complete control of the programming and content of the
         Services, in its sole discretion.

                                                                             2

          distribute the applicable Service in either the Basic Package,
          Expanded Basic Package, Digital Basic or Digital Tier Package but each
          Participating Member may distribute the applicable Service to
          Commercial Subscribers on any level of carriage except pay-per-view or
          pay-per-day.

     b.  Except as otherwise expressly provided in this Agreement, NCTC will not
         withdraw, discontinue, or reduce, or permit the applicable
         Participating Member Owner to withdraw, discontinue, or reduce
         distribution of any Service over any Participating Member after the
         introduction of the applicable Service in that Participating Member
         (whether the introduction occurs before, on or after the Commencement
         Date) unless and until:

         i.    The Participating Member has entered into a separate agreement
               with Network, the Service owner or any other Network-authorized
               distributor to distribute the Service via the Participating
               Member;

         ii.   The agreement through which NCTC has granted the Participating
               Member the right to distribute the Service via the Participating
               Member terminates;

         iii.  This Agreement terminates; or

         iv.   The Participating Member no longer distributes video programming
               through any agreement or arrangement with NCTC.

     c.  Participating Member will distribute each applicable Service to Service
         Subscribers full time, on a designated channel and in its entirety.

     d.  Each Participating Member Owner will employ reasonable security
         practices and procedures to prevent unauthorized reception of its
         distribution of the Services.

     e.  If a Participating Member discontinues carriage of any Service under
         this Agreement for any period, NCTC may not thereafter distribute the
         Service to that Participating Member unless Network gives its written
         consent to NCTC's re-addition of that Participating Member to the
         Schedule of Participating Members as an authorized Participating
         Member.

     f.  During the Term, NCTC and Participating Members will be solely
         responsible for obtaining and maintaining in full force and effect, at
         their own cost, any and all licenses, permits, consents, registrations
         and authorizations from any and all relevant authorities in the
         Distribution Areas required to distribute each Service as contemplated
         by this Agreement.

     g.  Any member of NCTC which is a party to a separate, individual
         affiliation agreement with Network, and which is current in all
         payments to Network, shall have the right to terminate that individual
         agreement and be added to Exhibit A as a Participating Member and
         include in this Agreement all systems covered in such separate,
         individual affiliation agreement. Upon being added to Exhibit A, the
         obligations of the Participating Member shall be governed by this
         Agreement, and not under such separate, individual affiliation
         agreement.

6    AD TIME.

     a.  Subject to underlying programming restrictions (e.g., commercial
         advertising formats) and limitations in underlying programming
         agreements, Network will make available 4 minutes of advertising time
         in each hour of each Service to NCTC or to the Participating Member,
         for advertising insertion on each System at NCTC's or Participating
         Member's expense (the "AD TIME"), as positioned by Network in its sole
         discretion and to be allocated on a reasonably even basis among the
         advertising spots available to Network in each hour of each Service. In
         those Service programs where there are fewer than that number of
         minutes per hour of advertising time available to Network, Network will
         make available to NCTC or to the Participating Member as their Ad Time
         only that lesser amount of advertising time, if any, in those programs
         instead of number of minutes per hour otherwise required. As between
         Network and NCTC, NCTC or Participating

                                                                             3

         Member is responsible for all costs of, and NCTC or Participating
         Member is entitled to all proceeds from, NCTC's or any Participating
         Member Owner's sales of Ad Time.

     b.  Neither NCTC nor any Participating Member Owner is entitled to Ad Time
         in direct on-air sales or for infomercial programming. NCTC and/or
         Participating Member may only use the Ad Time in conformance with
         applicable laws, regulations, rules, restrictions, and standards
         established by Network and provided to NCTC. NCTC and/or Participating
         Member will not use any Ad Time to advertise or promote tobacco
         products, distilled liquor, any "900," "976," or similar telephone
         solicitations that are sexual or prurient in content or directed at
         children, or material which is obscene, indecent, lewd or pornographic
         in whole or in part.

     c.  From time to time Network may notify NCTC and Participating Members of
         restrictions and standards governing use of Ad Time (including without
         limitation restrictions due to exclusive advertising categories
         granted by Network or its Service providers, and restrictions on
         advertising unaffiliated competitive programming services). These
         restrictions and standards may restrict the types of products or
         services that NCTC or Participating Member Owner may insert in their
         ad time in certain programming events. All Ad Time sold or committed
         by NCTC or any Participating Member Owner after notice of those
         restrictions and standards will comply with those restrictions and
         standards.

7.   FEES AND REPORTS.

     a.  Within 45 days after the end of each calendar month during the Term,
         NCTC will pay Network, with respect to each Participating Member and
         each Service carried by that Participating Member, a monthly fee equal
         to the number of each Participating Member's Service Subscribers
         multiplied by the Participating Member's applicable Base Rate set forth
         on the attached Rate Card ("RATE CARD"), except that for each
         Commercial Subscriber, NCTC will instead pay Network the Commercial
         Subscriber Rate in subsection (g) below. NCTC will also provide Network
         a true and complete report for the prior calendar month signed by
         NCTC's chief financial officer or his authorized designee, specifying
         all information necessary for Network to compute the fees due for the
         month. NCTC will pay Network these fees for each Service Subscriber
         whether or not the Participating Member Owners receive payment from
         their respective Service Subscribers. NCTC shall have no liability for
         subscriber fees of any Participating Member which accrue after the end
         of the calendar month immediately following the date upon which Network
         is notified by NCTC that a particular Participating Member has failed
         to pay subscriber fees when due. In return for providing group billing
         and collection services to Network in respect of Participating Members,
         NCTC shall be paid a fee equal to two percent (2%) of each months'
         subscriber fees collected by NCTC, which amount may be paid by NCTC
         deducting same from its remittances to Network.

     b.   PAYMENTS. NCTC will pay the fees under this Agreement by delivering
          them to Network at the address given at the end of this Agreement (or
          any other location Network may designate in writing). Amounts past due
          from NCTC will accrue interest at the lesser of 1.5% per month or the
          maximum lawful rate from due date until paid. NCTC will reimburse
          Network for all of Network's reasonable costs and expenses of
          collecting overdue amounts, including court costs and attorneys' fees.

     c.   NCTC will maintain complete and accurate books and records relating to
          this Agreement, including accounts of billing. On reasonable notice
          and no more than twice in any 12-month period, Network and its agents
          may inspect, make copies of, and otherwise audit those books and
          records at NCTC's offices during business hours. Network's right to
          audit will survive for 24 months after termination of this Agreement.
          If an audit finds that there has been underpayment of 10% or more,
          then NCTC will promptly reimburse Network for the cost of the audit.
          NCTC will have the right to seek credits for any overpayments of fees
          it has made.

     d.  NCTC will require each Participating Member to maintain, during the
         Term and for 2 years after its end, complete and accurate books and
         records relating to the Participating Member's distribution of each
         Service. NCTC will require each Participating Member to allow Network,
         on reasonable notice to NCTC, to inspect, make copies of, and otherwise
         audit those books and records at the Participating Member's offices
         during business hours. Network's right to audit under this subsection
         (d) will survive for 24 months after termination or expiration of this
         Agreement. Network may not audit any Participating Member more than
         twice in any 12-month period. If an audit finds any underreporting of
         Service Subscribers by the

                                                                             4
<PAGE>

         Participating Member, NCTC will promptly pay Network the fees required
         under this Agreement for the unreported Service Subscribers, whether
         or not the Participating Member has paid NCTC for those Service
         Subscribers.

     e.  Neither party may commence any action to offset or recover any
         overpayment or underpayment of fees under this Agreement more than 2
         years after the fees were due.

     f.  NUMBER OF SERVICE SUBSCRIBERS. For purposes of calculating fees, the
         number of a Participating Member's Service Subscribers for the
         applicable Service for any calendar month is:

         i.       the number of its Service Subscribers in single-family homes
                  as of the last day of the month; PLUS

         ii.      the number of its Service Subscribers in Multi-Unit Facilities
                  as of the last day of the month, calculated on an "equivalent
                  subscriber" basis as described below ("EQUIVALENT
                  SUBSCRIBERS").

     g.  CALCULATION OF EQUIVALENT SUBSCRIBERS.

         i.   If a Participating Member serves subscribers in one or more
              Multi-Unit Facilities and subscribers in single-family homes, the
              number of its Equivalent Subscribers in a Multi-Unit Facility is
              calculated by dividing (A) the monthly charge for the Multi-Unit
              Facility for the programming package containing the applicable
              Service, by (B) the lowest monthly rate the Participating Member
              charges single-family home subscribers for the same or a
              substantially similar programming package.

         ii.  If a Participating Member serves subscribers in a Multi-Unit
              Facility only, the number of its Equivalent Subscribers for a
              Multi-Unit Facility is calculated by dividing (A) the monthly
              charge for the Multi-Unit Facility for the programming package
              containing the applicable Service, by (B) the National Cable
              Television Association's annually adjusted industry average
              cable television Participating Member retail rate for
              programming packages substantially similar to the package that
              contains the applicable Service.ii.

     h.  COMMERCIAL SUBSCRIBER RATE. NCTC will pay Network a monthly fee for
         each Commercial Subscriber equal to the greater of (i) twice the
         applicable Base Rate and (ii) 50% of the rate charged by the
         Participating Member Owner for the Commercial Subscriber.

    i.   MORE FAVORABLE FEES. Network agrees that if at any time during the Term
         Network provides the service to any other multi-channel video
         programming distributor having an equal or lesser number of Service
         Subscribers than the Participating Members in the aggregate (an `Equal
         Distributor') on the basis of a rate card which is more favorable than
         the rate card attached hereto, Network shall promptly notify NCTC in
         writing, and NCTC shall immediately be entitled to incorporate into
         this Agreement the rate card applicable to the Equal Distributor for
         the benefit of the Participating Members effective on the first day of
         the month following the date Network first allows such Equal
         Distributor to distribute the Service on the basis of such more
         favorable rate card.

     8.  COPYRIGHT AND TRADEMARK. NCTC and Participating Members recognize
         Network's exclusive right, title and interest in and to the copyright
         for the Services and programming, including the marks, names and logos
         of the programming used at any time during the Term. Neither NCTC nor
         Participating Members will authorize, cause, or permit any Service or
         other material furnished by Network to NCTC or Participating Members
         pursuant to this Agreement to be recorded, duplicated, rebroadcast or
         otherwise transmitted or used for any purpose other than distribution
         as permitted herein. NCTC and Participating Members recognize that the
         service marks, trademarks, trade names, logos and other material used
         for the distribution and promotion of the Services and their
         programming ("MARKS") are the exclusive property of Network and that
         neither NCTC nor Participating Members acquire any proprietary rights
         in the Marks by reason of this Agreement. Notwithstanding the
         foregoing, promotional materials provided by Network and uses of Marks
         in a factual manner in routine promotional materials such as program
         guides, program listings, and bill stuffers, if consistent with
         Network's prior uses, are deemed approved unless Network otherwise
         notifies NCTC or Participating Members.

9.   INDEMNITIES; DAMAGES.

                                                                             5
<PAGE>

     a.  Network will indemnify NCTC against all liabilities, claims, costs,
         damages and expenses (including reasonable attorneys' fees and court
         costs) (collectively "CLAIMS") relating to or arising out of Network's
         breach of this Agreement.

     b.  Network will indemnify NCTC against all Claims arising out of the use
         of or relating to the content of any Service furnished by Network to
         and distributed by NCTC in accordance with this Agreement, excluding
         the Claims of any music performing rights association (such as ASCAP,
         BMI) that a separate music performance rights license is required for
         any Participating Member's distribution of the Service from its headend
         to its Service Subscribers, and excluding any programming materials
         added to advertisements inserted into the Services by NCTC or a
         Participating Member pursuant to Section 7. Notwithstanding the
         preceding sentence, Network will use reasonable efforts to negotiate a
         single license fee (covering both Network's transmission of the Service
         to the Participating Members and the Participating Members'
         distribution of the Service to their Service Subscribers) for the
         transmission of copyrighted musical works in the Service.

     c.  NCTC will indemnify Network against all Claims relating to or arising
         out of any of the following:

         i.       NCTC's breach of this Agreement;

         ii       alteration of, delay of, insertion of material into, or
                  deletion of material from the Service by NCTC or any
                  Participating Member or Participating Member Owner;

         iii.     use of the Service by any of NCTC's clients or customers
                  (including any Participating Member or Participating Member
                  Owner) in violation of this Agreement;

         iv.      a dispute between or among NCTC and any Participating Member
                  or Participating Member Owner.

     d.  The party seeking indemnification will promptly notify the other party
         in writing of a Claim for which such indemnity applies. The
         indemnifying party may assume the defense of all Claims to which its
         indemnity applies. The indemnified party will cooperate fully with the
         indemnifying party (at the indemnifying party's expense) in defending
         and settling Claims. The indemnifying party will not have to provide
         indemnity if the party seeking indemnity settles a Claim without the
         indemnifying party's written consent. This Section will survive
         termination or expiration of this Agreement.

     e.  DAMAGES LIMITED. Notwithstanding the foregoing, Network will not be
         liable to NCTC or any person claiming through NCTC for any incidental
         or consequential damages or loss of revenues, whether foreseeable or
         not, caused by any breach of this Agreement by Network.

10.  LEGAL COMPLIANCE.

     a.  GENERAL. Each party will comply with all applicable laws, rules,
         regulations, and government requirements, including but not limited to
         those adopted under Section 713 of the Telecommunications Act of 1996.

     b.  COMPLIANCE WITH CHILDREN'S TELEVISION ACT. Network will comply in all
         respects with the limitations of the Children's Television Act of 1990
         and the regulations of the FCC promulgated thereunder as they apply to
         Network with respect to cable television Participating Members and
         cable operators. If Network provides children's programming, Network
         will provide all records and certifications that NCTC may reasonably
         request, demonstrating compliance under the Children's Television Act
         regulations as are necessary for NCTC to timely demonstrate its
         compliance with the cable recordkeeping requirements of the Children's
         Television Act regulations.

                                                                             6
<PAGE>

11.  FORCE MAJEURE. Neither Network nor NCTC will incur any liability to the
     other for any delay, preemption or other failure to perform when such
     delay, preemption or failures is due to any cause beyond the control of the
     party whose performance is so affected, including without limitation an act
     of God, fire, war, strike, riot, labor dispute, natural disaster, technical
     failure (including the failure of all or part of the equipment of others),
     failure of performance of any entity with which Network has a contract for
     the supply of programming, or any legal prohibition, decree, regulation or
     requirement of any governmental authority having jurisdiction ("FORCE
     MAJEURE"). But if Force Majeure prevents Network's delivery of any Service
     to any Participating Member for more than 12 hours in any month such that
     the Participating Member is prevented from delivering the Service to its
     Service Subscribers (although the change in the availability or scheduling
     of any particular Service programming will not be considered non-delivery
     of the Service so long as substitute programming replaces the unavailable
     or re-scheduled programming), then Network will reduce the Participating
     Member's monthly fee per Service Subscriber for that month and that Service
     by the lesser of (a) the same percentage, if any (not exceeding 100%), by
     which that Participating Member has reduced its monthly Service fees to its
     Service Subscribers due to the interruption, or (b) the percentage that the
     number of hours of interruption bears to the total number of hours of the
     Service that the Participating Member would otherwise have distributed.

12.  TERMINATION.

     a.  Besides its other rights at law or equity, Network may terminate this
         Agreement on notice to NCTC: (i) if NCTC or any Participating Member or
         Participating Member Owner breaches any material term of this
         Agreement; but if the breach is curable, then Network may not exercise
         its termination rights or other rights at law or in equity for that
         breach unless that breach is not fully cured within 30 days (10 days if
         a monetary breach) of the notice of breach; (ii) if NCTC becomes
         insolvent, files a petition in bankruptcy, or seeks relief under any
         similar law related to its financial condition; or (iii) if any person
         files an involuntary petition in bankruptcy against NCTC, or seeks
         relief under any similar law related to NCTC's financial condition,
         unless the involuntary petition is dismissed or relief is denied within
         30 days after it has been filed or sought. The termination of this
         agreement by Network in respect of any Participating Member or the
         termination of this agreement by any Participating Member in respect of
         Network shall have no effect upon this Agreement as among Network, NCTC
         and the other Participating Members.

     b.  Besides its other rights at law or in equity, NCTC may terminate this
         Agreement on notice to Network if: (i) Network breaches any material
         term of this Agreement, but if the breach is curable, then NCTC may not
         exercise its termination rights or other rights at law or in equity for
         that breach unless that breach is fully cured within 30 days of the
         notice of termination; or (ii) Network files a petition in bankruptcy,
         is insolvent, or seeks relief under any similar law related to its
         financial condition; or (iii) if any person files an involuntary
         petition in bankruptcy against Network, or seeks relief under any
         similar law related to Network's financial condition, unless the
         involuntary petition is dismissed or relief is denied within 30 days
         after it has been filed or sought.

     c.  This Agreement expires automatically with respect to any Service that
         Network discontinues.

13.  TAXES. All fees under this Agreement are net of taxes. NCTC or
     Participating Member is responsible for all taxes, franchise fees and
     similar charges (a) levied on NCTC or Participating Member, (b) related to
     any Participating Member or its sale or use of any Service, or (c) related
     to NCTC's distribution of any Service to any Participating Member. NCTC
     represents that it and each Participating Member are acquiring each Service
     for resale only.

14.  ASSIGNMENT; THIRD PARTIES.

     a.  This Agreement and its obligations and benefits will bind each party's
         respective transferees and successors, but NCTC may not assign or
         otherwise transfer this Agreement in whole or in part by operation of
         law or otherwise, without Network's prior written consent. No provision
         of this Agreement is intended to, and may not be construed to, provide
         or create any third-party beneficiary right or any other right of any
         kind in favor of any client, customer (including any Participating
         Member) , affiliate, shareholder, partner, officer, director, employee,
         or agent of NCTC. In the event of any valid assignment of this
         Agreement by Network, Network will be relieved of all obligations
         arising after such assignment and NCTC and Participating Members will
         look solely to the assignee for performance of such obligations.

                                                                             7
<PAGE>

     b.   NCTC will require each Participating Member to notify NCTC promptly of
          any sale of any of its Participating Members or change in control of
          the Participating Member, and NCTC will then notify Network promptly
          of any sale of any Participating Member or change in control of any
          Participating Member. If a sale or change in control is to a
          Participating Member with which Network has a then effective agreement
          to distribute any Service, Network may, by giving NCTC 30 days'
          notice, delete that Participating Member Participating Member(s) from
          that Service's listing on the Schedule of Participating Members, in
          which case NCTC will have no further right to distribute the Service
          to that Participating Member(s).

15.  CHOICE OF LAW.

     a.   This Agreement is subject to the Communications Act of 1934, as
          amended, the Cable Television Consumer Protection and Competition Act
          of 1992 and the rules promulgated by the FCC pursuant to the foregoing
          and all applicable federal, state and local statutes and laws.

     b.   THIS AGREEMENT AND ALL COLLATERAL MATTERS RELATING THERETO WILL BE
          CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS,
          APPLICABLE TO AGREEMENTS FULLY MADE AND TO BE PERFORMED ENTIRELY
          WITHIN SUCH STATE.

16.  PRIOR AFFILIATION AGREEMENTS. Effective the Commencement Date, this
     Agreement will supersede each affiliation agreement in existence on the
     Commencement Date between NCTC (or its predecessors in interest) and any
     owner of any Service covered by this Agreement (or the predecessors of any
     owner), for carriage of any Service covered by this Agreement.

17.  NOTICE. Unless this Agreement otherwise permits, a party's notice under
     this Agreement will be effective only if in writing and sent by overnight
     delivery or registered or certified U.S. mail to the party's address given
     below. Notice sent by overnight delivery will be effective on the next
     business day after timely delivery to the overnight courier. Notice sent by
     mail will be effective on the third day after posting. A party may change
     its address by giving the other party notice of its new address.

18.  COMPLETE UNDERSTANDING. This Agreement, including the Schedule of
     Participating Members, contains the entire understanding of the parties and
     supersedes all their prior or contemporaneous oral understandings and all
     their prior written understandings relating to the subject matter of this
     Agreement.

19.  WAIVER. No waiver of any right under, and no amendment to, this
     Agreement will be effective unless in writing and signed by both
     parties.

20.  DRAFTING. No provision of this Agreement may be interpreted against any
     party because that party or its legal representative drafted the
     provision.

21.  CONFIDENTIALITY. NCTC will not disclose the terms of this Agreement to any
     third party (other than to its respective employees, attorneys,
     accountants, members and prospective members that have signed a
     confidentiality agreement and other agents on a need-to-know basis in their
     capacity as such, requiring them to maintain the same non-disclosure)
     without Network's consent.

22.  RESERVATION OF RIGHTS. Network reserves, and may exercise as it
     chooses, all rights to the Service not specifically granted to NCTC
     under this Agreement.

23.  NO PERSONAL RECOURSE. Any recourse of either party against the other
     under or relating to this Agreement extends only to that party and not
     to any employee, owner, shareholder, partner, member, director,
     officer, or agent of that party.

24.  SEVERABILITY. The invalidity of any provision of this Agreement will not
     affect the validity of any other provision, except that the parties
     acknowledge that the carriage requirements in Section 5 of this Agreement
     comprise an essential element of the consideration to Network such that, if
     one or more of the carriage requirements were held to be invalid, illegal
     or unenforceable, Network may, in its sole discretion, terminate this
     Agreement with respect to some or all of NCTC's Participating Members upon
     60 days' written notice to NCTC.

                                                                             8
