     (c) The holders of the Class A-1  Certificates  will be entitled to receive

               Certificateholders  representing  100% of the Voting  Rights with
               respect thereto; and

                    (2)  second,  to the  holders of the Class A-1  Certificates
               until the Certificate  Principal  Amount thereof has been reduced

& Co.  Inc.,  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(b) hereof.

     (d) 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

                                       8
<PAGE>

than 30 days after the receipt of such moneys or other property, the Trustee
will allocate and distribute such property to the holders of Class A-1
Certificates then outstanding and unpaid, (after deducting the costs incurred in
connection therewith) in accordance with the priorities of distribution
established pursuant to 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 property to Certificateholders
will be deemed to reduce the principal amount of Certificates on a
dollar-for-dollar basis.

     (e)  Subject to Section  9(f)  hereof,  to the extent  Available  Funds are
insufficient  to  make  any  required   distributions   due  to  the  Class  A-1
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(f) hereof) on which  sufficient  funds are  available on the Available
Funds to pay such shortfall.

     (f) 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.

     (g) [Reserved].

     (h)  Notwithstanding  Section 3.12 of the Standard Terms, if the Underlying
Securities  Guarantor  ceases to file  periodic  reports as  required  under the
Exchange Act, the Depositor shall within 5 Business Days instruct the Trustee to
sell the  Underlying  Securities and distribute the proceeds of such sale to the
Certificateholders in accordance with the order of priority set forth in Section
5(a)  provided,  however,  the  Depositor  shall not  instruct  the  Trustee  to
distribute or sell the Underlying  Securities pursuant to this clause unless the
Underlying Securities Guarantor has either (x) stated in writing that it intends
permanently  to cease  filing  reports  required  under the  Exchange Act or (y)
failed to file any required reports for one full calendar year.

     Section 6. Trustee's Fees. (a) As compensation for its services  hereunder,
the Trustee  shall be entitled to the Trustee Fee as agreed to  separately  in a
fee agreement among the Depositor and the Trustee. 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  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

                                       9
<PAGE>

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. Redemption Upon Exercise of Call Warrants.

     (a) [Reserved].

     (b) On any Call Date, Class A-1 Certificates  shall be redeemed at par plus
accrued and unpaid  interest on the Class A-1  Certificates  upon receipt by the
Trustee  of the Call  Price on or prior to such Call  Date.  On any Call Date on
which one or more of the Rights Holders duly exercises less than all of the Call
Warrants then outstanding,  the Class A-1 Certificates shall be redeemed in part
and the Class A-1 Certificates to be redeemed will be selected by the Trustee or
DTC by lot and will be paid for on the Call Date.

          (i)  Any Rights Holder, in order for it to exercise its Call Rights in
               whole or in part,  shall  provide  notice to the Trustee (a "Call
               Request")  no more than 60 or less than 35 days prior to any Call
               Date,  that it is  exercising  its Call Rights on such Call Date,
               indicating  the principal  amount of Underlying  Securities as to
               which such call will be exercised.

          (ii) Deliveries  of the  Underlying  Securities  purchased on any Call
               Date by a  Rights  Holder  (the  "Purchaser")  will  only be made
               against  payment by the  Purchaser of the Call Price with respect
               to such  Underlying  Securities 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  exercise  of Call  Rights will be deemed
               not to be  effective  with  respect  to such Call  Date,  and the
               Certificates  and  the  Call  Rights  shall  continue  to  remain
               outstanding. Subject to receipt of the Call Price as aforesaid on
               any Call Date, the Trustee shall pay the corresponding redemption
               price  set  forth  in  clause  (b),   above,  to  the  Class  A-1
               Certificateholders on such Call Date.

          (iii)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 the Rights Holders.

          (iv) The  Trustee  shall not be  obligated  to  determine  whether  an
               exercise of Call Rights  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.

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

                                       10
<PAGE>

          (vi) The Rights Holder shall  initially be the Depositor and such Call
               Rights may be  transferred to one or more holders.  However,  the
               Trustee  is  under no  obligation  to  recognize  any  notice  of
               transfer   unless  it  is  signed  by  the   transferor  and  the
               transferee.

         (vii) Any  exercise  of Call  Rights  by a Rights  Holder  must be in a
               minimum  principal  amount  of  Underlying  Securities  equal  to
               $500,000 and integral multiples of $500,000 in excess thereof.

        (viii) Any  exercise of Call Rights by a Rights  Holder must include a
               certification  by the Rights  Holder that it is solvent as of the
               Call Date.

     Section 8. Events of Default.

     Within 30 days of the  occurrence of an Event of Default  actually known to
the  Trustee,  the Trustee  will give notice to the  Certificateholders  and the
Rating Agency,  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  from  the
Certificateholders  if in good faith it determines  that the withholding of such
notice is in the interest of the Certificateholders.

     Section 9. Miscellaneous.

     (a) The provisions of Section 4.04,  Advances,  of the Standard Terms shall
not apply to the Series 2001-4 Certificates.

     (b) The  provisions of Section  4.07,  Optional  Exchange,  of the Standard
Terms shall not apply to the Series 2001-4 Certificates.

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

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

     (e) The provisions of Section 3.07(d) of the Standard Terms shall not apply
to the Series 2001-4 Certificates.

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

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

                                       11
<PAGE>

     (h) The Trust may not engage in any  business or  activities  other than in
connection  with, or relating to, the holding,  protecting and preserving of the
Trust  Property  and the  issuance  of the  Certificates,  and other  than those
required or  authorized by the Trust  Agreement or  incidental  and necessary to
accomplish such activities.  The Trust may not issue or sell any certificates or
other  obligations  other than the  Certificates or otherwise  incur,  assume or
guarantee any indebtedness for money borrowed.

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

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

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

     (l) In relation to Section  7.01(f) of the  Standard  Terms,  any  periodic
reports  filed by the Trustee  pursuant to the  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.

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

     (n) 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.

     (o) All  directions,  demands and notices  hereunder  or under the Standard
Terms shall be in writing  and shall be  delivered  as set forth  below  (unless
written notice is otherwise provided to the Trustee).

     Section 10.  Governing Law. THIS SERIES SUPPLEMENT AND THE TRANSACTIONS
DESCRIBED HEREIN SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND PERFORMED WITHIN
THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO THE CHOICE OF LAWS PROVISIONS
THEREOF.

     Section 11.  Counterparts.  This Series  Supplement  may be executed in any
number of counterparts, each of which shall be deemed to be an original, and all
such counterparts shall constitute but one and the same instrument.

     Section 12.  Termination of the Trust.  The Trust shall  terminate upon the
earliest  to occur of (i) the  payment in full at  maturity or sale by the Trust
after a payment  default on or an  acceleration  or other  early  payment of the
Underlying  Securities  and the  distribution  in full of all amounts due to the
Class  A-1  Certificateholders;  (ii)  the  payment  in  full of the  Class  A-1
Certificates  upon exercise of all of the issued Call Rights under Section 7(b);
and (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.

     Section 13. Sale of  Underlying  Securities.  In the event of a sale of the
Underlying Securities pursuant to Section 5(d) hereof, the Liquidation Proceeds,
if any, shall be deposited into the Certificate  Account for distribution to the
Class A-1  Certificateholders  pursuant to Section 5(a).  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 the Class A-1  Certificateholders  unless the Rating
Agency Condition is satisfied with respect to such amendment.

     Section 15. Voting of Underlying Securities, Modification of Indenture. The
Trustee, as holder of the Underlying Securities,  has the right to vote and give
consents and waivers in respect of the Underlying Securities as permitted by the
Depository and except as otherwise limited by the Trust Agreement.  In the event
that the  Trustee  receives  a  request  from  the  Depository,  the  Underlying
Securities  Trustee or the Underlying  Securities  Issuer for its consent to any
amendment, modification or waiver of the Underlying Securities, the Indenture or
any other  document  thereunder  or  relating  thereto,  or  receives  any other
solicitation  for any action  with  respect to the  Underlying  Securities,  the
Trustee shall mail a notice of such proposed amendment,  modification, waiver or
solicitation  to each  Certificateholder  of record as of such date. The Trustee
shall request instructions from the  Certificateholders  as to whether or not to
consent  to  or  vote  to  accept  such  amendment,   modification,   waiver  or
solicitation.  The Trustee

                                       14
<PAGE>

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 Certificates 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, after weighing the votes of the
Certificateholders; provided, however, that, notwithstanding anything in the
Trust Agreement to the contrary, the Trustee shall at no time vote on or consent
to any matter (i) unless such vote or consent would not (based on an opinion of
counsel) 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, or (iii) which would result in the
exchange or substitution of any of the outstanding Underlying Securities
pursuant to a plan for the refunding or refinancing of such Underlying
Securities except in the event of a default under the Indenture and only with
the consent of Certificateholders representing 100% of the Voting Rights with
respect thereto. 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  Certificateholders  of such
offer  promptly.  The Trustee  must reject any such offer  unless the Trustee is
directed by the affirmative vote of the Certificateholders  representing 100% of
the Voting Rights with respect  thereto to accept such offer and the Trustee has
received the tax opinion described above.

     If an event of default under the Indenture occurs and is continuing, and if
directed by Class A-1 Certificateholders  representing 51% or more of the Voting
Rights with respect thereto, 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.

                                       15

Depositor and the Trustee and the rights of the Certificateholders under the
Trust Agreement at any time by the Depositor and the Trustee with the consent of
the holders of Class A-1 Certificates in the manner set forth in the Series

governmental charge that may be imposed in connection with any transfer or
exchange of Certificates.

The Depositor and the Trustee and any agent of the Depositor or the Trustee may
treat the Person in whose name this Certificate is registered as the owner

agent shall be affected by any notice to the contrary.

It is the intention of the parties to the Trust Agreement that the Trust created
thereunder shall constitute a fixed investment trust for federal income tax
purposes under Treasury Regulation Section 301.7701-4, and the Certificateholder
agrees to treat the Trust, any distributions therefrom and its beneficial
interest in the Certificates consistently with such characterization.

Trust Agreement with respect to the Certificates shall terminate upon the
earliest to occur of (i) the payment in full at maturity or sale by the Trust
after a payment default or an acceleration or other early payment of the
Underlying Securities and the distribution in full of all amounts due to the
Class A-1 Certificateholders; (ii) the payment in full of the Class A-1
Certificates upon exercise of all of

to provide certain employees with benefits which they would otherwise lose under
The Thomas & Betts Pension Plan (the "Pension Plan") as a result of (i) certain
Internal Revenue Code limitations on benefits which may be provided under the
Pension Plan or (ii) elective deferrals of compensation under The Thomas & Betts
Supplemental Executive Investment Plan (the "SEIP");

     WHEREAS, the Company intends that the Plan be unfunded and be maintained
"primarily for the purpose of providing deferred compensation for a select group
of management or highly compensated employees," within the meaning of sections
201(2), 301(a)(3) and 401(a)(1) of the Employee Retirement Income Security Act
of 1974, as amended; and

     WHEREAS, the Company wishes to amend the Plan to permit benefits, the
present value of which exceeds $25,000, to be paid in a lump sum at the sole
discretion of the Retirement Plans Committee;

     NOW, THEREFORE, effective December 31, 2000, the Company hereby amends and
restates the Thomas & Betts Pension Restoration Plan as follows:

actuarial equivalent present value of the Pension Restoration Benefit to which a
Participant is entitled exceeds $25,000, the Retirement Plans Committee may, in

survivor annuity is payable from the Pension Plan to his surviving spouse, a
Surviving Spouse Benefit shall be payable from this Plan. The

                                      -5-

amount of such Surviving Spouse Benefit shall be equal to the monthly

          (b) the Participant had not elected to defer any of his Compensation

Section 4.2, if the actuarial equivalent present value of the Surviving Spouse
Benefit to which a surviving spouse is entitled does not exceed $25,000, such

actuarial equivalent present value of the Surviving Spouse Benefit to which a
surviving spouse is entitled exceeds $25,000, the Retirement Plans Committee
may, in its sole discretion, require that the present value be distributed to
the surviving spouse in a lump sum. For purposes of this Section 4.3, the
actuarial equivalent present value of a surviving spouse's Surviving Spouse
Benefit shall be determined as of February 1 of the calendar year following the
calendar year in which the Participant dies, using the interest and mortality
assumptions which would be used under the Pension Plan for purposes of
determining lump sum present values as of

                                      -6-

such determination date. Any lump sum benefit payable under this Section 4.3
shall be paid within 60 days following the applicable determination date.

having the care and custody of the minor, incompetent or incapable person. The
Committee or its appointed representative may require proof of incompetency,

distribution of the amount. The distribution shall completely discharge the
Committee and its appointed representative and the Employer from all liability
with respect to the amount distributed.

payable under this Plan.

     Section 5.5 NONALIENATION OF BENEFITS. Except as provided in Section 5.4
with respect to certain domestic relations orders, none of the benefits or

the claim of any creditor. In particular, to the fullest extent permitted by
law, all such benefits and rights shall be free from attachment, garnishment or
any other legal or equitable process available to any creditor of the
Participant or his Beneficiary. Neither the Participant nor his Beneficiary
shall have the right to alienate, anticipate, commute, pledge, encumber or
assign any of the payments which he may expect to receive, contingently or
otherwise, under this Plan.

asset which may be set aside, earmarked or identified as being intended for the
provision of benefits under this Plan, shall remain an asset of the Employer and
shall be subject to the claims of its general creditors. Each Participant and
Beneficiary shall be a general creditor of the Employer to the extent of the
value of his benefit accrued hereunder, and he shall have no right, title or
interest in any specific

                                      -8-

asset that the Employer may set aside or designate as intended to be applied to

representative shall keep a record of its proceedings and actions and shall

under the Plan, against any and all claims, losses, damages, expenses and
liabilities arising from their carrying out of their responsibilities in

     Section 7.5 CLAIMS PROCEDURE. The procedure for presenting claims under the

     appointed representative.

          (b) NOTICE OF DENIAL OF CLAIM. In the event of a denial of any benefit
     requested by any claimant, the claimant shall be given a written
     notification containing specific reasons for the denial. The written
     notification shall contain specific reference to the pertinent Plan
     provisions on which the denial is based. In addition, it shall contain a
     description of any additional material or information necessary for the
     claimant to perfect a claim and an explanation of why such material or
     information is necessary. The notification shall also provide appropriate
     information as to the steps to be taken if the claimant wishes to submit
     his claim for review.

          The written notification shall be given to the claimant within 90 days
     after receipt of his claim by the Committee or its appointed representative
     unless special circumstances require an extension of time for processing,
     in which case written notice of the extension shall be furnished to the
     claimant prior to the termination of the original 90-day period, and such
     notice shall indicate the special circumstances which make the extension

     in writing. In addition, the claimant may make a written request for a
     review of his claim and its denial by the Committee or its appointed

     of written notification of the denial of the claim.

          appointed representative within 60 days after the receipt of the
          request for review. However, where special circumstances make a longer
          period for decision necessary or appropriate, the decision of the
          Committee or its appointed representative may be postponed on written
          notice to the claimant (prior to the expiration of the initial 60-day
          period) for an additional 60 days. In no event shall the decision of
          the Committee or its appointed representative be rendered more than
          120 days after the receipt of the request for review.

               (2) Any decision by the Committee or its appointed representative
          shall be furnished to the claimant in writing in a manner calculated
          to be understood by the claimant and shall set forth the specific
          reason(s) for the decision and the specific Plan provision(s) on which
          the decision is based.
