PROSPECTUS
            Receipts on Corporate Securities Trust, Series NSC 1998-1

               Offer to Exchange Receipts on Corporate Securities,
         Series NSC 1998-1, Amortizing Class, which have been registered
                  under the Securities Act of 1933, as amended,
                for any and all outstanding Receipts on Corporate
          Securities, Series NSC 1998-1, Amortizing Class The Exchange
              Offer will expire at 5:00 p.m., New York City time, on
                       February , 1999, unless extended.

     The Receipts on Corporate Securities, Series NSC 1998-1, Amortizing Class
(the "New Certificates") issued by the Receipts on Corporate Securities Trust,
Series NSC 1998-1 (the "Trust"), which have been registered under the Securities
Act of 1933, as amended (the "Securities Act"), pursuant to a Registration
Statement of which this Prospectus is a part, are hereby offered, upon the terms
and subject to the conditions set forth in this Prospectus and the accompanying
letter of transmittal (the "Letter of Transmittal" and, together with this
Prospectus, the "Exchange Offer"), in exchange for an equal Certificate
Principal Balance of outstanding Receipts on Corporate Securities, Series NSC
1998-1, Amortizing Class (the "Old Certificates"), of which $68,089,189.08
aggregate Certificate Principal Balance is outstanding as of the date hereof.
The Trust was formed pursuant to a trust agreement dated as of August 28, 1997
as amended by Base Amendment No. 1 dated as of February 27, 1998, and as
supplemented by the Series NSC 1998-1 Supplement dated as of April 13, 1998
(together, the "Trust Agreement") between Prudential Securities Structured
Assets, Inc., as depositor ("PSSA") and The Bank of New York, a New York banking
corporation, as trustee (the "Trustee"). The property of the Trust will consist
solely of $80,000,000 aggregate principal amount of 7.90% Notes due May 15, 2097
(the "NSC Notes") issued by Norfolk Southern Corporation ("NSC"), having the
characteristics described in its prospectus dated May 14, 1997 and a supplement
thereto dated May 14, 1997 (together, the "NSC Notes Prospectus"). The NSC Notes
were issued and sold as part of an underwritten public offering of $350,000,000
aggregate principal amount of such securities.

     Any and all Old Certificates that are validly tendered and not withdrawn on
or prior to 5:00 P.M., New York City time, on the date the Exchange Offer
expires, which will be February , 1999, (30 calendar days following the
commencement of the Exchange Offer) unless the Exchange Offer is extended (such
date, including as extended, the "Expiration Date"), will be accepted for
exchange. Tenders of Old Certificates may be withdrawn at any time prior to 5:00
P.M., New York City time on the Expiration Date. The Exchange Offer is not
conditioned upon any minimum principal amount of Old Certificates being tendered
for exchange. However, the Exchange Offer is subject to certain customary
conditions, which may be waived by the Trust, and to the terms of the
Registration Rights Agreement, dated as of April 13, 1998 (the "Registration
Rights Agreement"), between PSSA and Prudential Securities Incorporated, as
initial purchaser ("Prudential Securities"). Old Certificates may be tendered
only in minimum denominations of $250,000 Certificate Principal Balance and
integral multiples of $1.00 in excess thereof. See "The Exchange Offer".

     The New Certificates will be entitled to the benefits of the same Trust
Agreement that governs the Old Certificates and will govern the New
Certificates. The form and terms of the New Certificates are the same in all
material respects as the form and terms of the Old Certificates, except the New
Certificates have been registered under the Securities Act and therefore will
not bear certain legends restricting the transfer thereof. The New Certificates
will be issued in fully registered, certificated form. See "The Exchange Offer"
and "Description of the New Certificates".

     The Trust issued the Receipts on Corporate Securities Series NSC 1998-1
(the "Trust Certificates") in two Series: the Amortizing Class and the Residual
Class, which collectively represent the entire beneficial ownership of the
Trust. Subject to the occurrence of an Optional Redemption, a Shortened Maturity
Redemption, or an In-Kind Distribution (each as defined herein), the Residual
Class Certificates evidence fractional undivided beneficial interests in all
principal payments on the NSC Notes, and in interest accrued and paid on the NSC
Notes after May 15, 2017 at a rate of 7.90% per annum, compounded semiannually.
Subject to such occurrences, the Amortizing Class Certificates evidence
fractional undivided beneficial interests in all payments of interest accrued
and paid on the NSC Notes on or before May 15, 2017. The Trust Certificates were
purchased at an original issue discount. Subject to the occurrence of an
Optional Redemption or a Shortened Maturity Redemption, no cash distributions
will be made on the Residual Class Certificates. Instead, the Residual Class
Certificates outstanding on May 15, 2017 will be terminated and deemed
involuntarily surrendered by the holders thereof in exchange for a principal
amount of the NSC Notes underlying such Residual Class Certificates equal to the
aggregate Certificate Principal Balance of such Residual Class Certificates.




     The NSC Notes may be redeemed prior to maturity, as a whole or in part, at
the option of NSC (an "Optional Redemption"), upon not less than 30 nor more
than 60 days' prior written notice, at any time, at a redemption price equal to
the greater of (i) 100% of the principal amount being redeemed and (ii) the sum
of the present values of the remaining scheduled payments of principal and
interest thereon discounted to the date of redemption (an "Optional Redemption
Date") on a semiannual basis at the Treasury Yield (as defined herein) plus 20
basis points, together with accrued interest to the date of redemption.

     Upon the occurrence of a Tax Event (as defined herein) with respect to the
NSC Notes, NSC has the right to shorten the maturity of the NSC Notes (i) to the
minimum extent required, in the opinion of nationally recognized independent tax
counsel to NSC, such that, after the shortening of the maturity, interest paid
on the NSC Notes will be deductible for U.S. federal income tax purposes or,
(ii) if such counsel is unable to opine definitively as to such minimum period,
the minimum extent so required as determined in good faith by the Board of
Directors of NSC after receipt of an opinion of such counsel regarding the
applicable legal standards. (Any such new maturity date is referred to herein as
the "Shortened Maturity Date," and the redemption of the NSC Notes effected on
such date is referred to as a "Shortened Maturity Redemption.")

     In the event of an Optional Redemption or a Shortened Maturity Redemption,
the Certificates will be redeemed on the Optional Redemption Date or the
Shortened Maturity Date. In such event, the Trustee will distribute the payment
received on the NSC Notes on the Optional Redemption Date or the Shortened
Maturity Date, as the case may be, to the holders of the Amortizing Class
Certificates and the Residual Class Certificates, respectively, in the same
ratio as (i) the present value of all originally scheduled future payments on
the Amortizing Class Certificates bears to (ii) the present value of all
originally scheduled future payments on the NSC Notes after May 15, 2017,
discounted semiannually in each case at a rate of 7.90% per annum to the
Optional Redemption Date or the Shortened Maturity Date. Such ratio will be
calculated by the Company, as calculation agent. In the case of an Optional
Redemption of less than all of the NSC Notes, the Trustee will distribute the
payment received on the NSC Notes on the Optional Redemption Date to the holders
of the Amortizing Class Certificates and the Residual Class Certificates on the
basis of the foregoing ratio as of the Optional Redemption Date on a pro rata
basis; such a distribution will result in a reduction (based on the percentage
of NSC Notes redeemed) of the Residual Class Certificates Certificate Principal
Balance and a recalculation of the Certificate Principal Balance of, and Fixed
Payments (as defined in the Trust Agreement) with respect to, the Amortizing
Class Certificates based on the remaining NSC Notes after such redemption.

     Losses realized on the NSC Notes will be borne by the holders of the Trust
Certificates in the manner described herein. See "Risk Factors--Events of
Default" herein.

     NSC did not participate in, and did not receive any proceeds in connection
with, the sale of the Trust Certificates.

     Based on interpretations by the staff of the Securities and Exchange
Commission (the "Commission"), as set forth in no-action letters issued to third
parties, including Exxon Capital Holdings Corporation, SEC No-Action Letter
(available April 13, 1989), Morgan Stanley & Co. Incorporated, SEC No-Action
Letter (available June 5, 1991) and Shearman & Sterling, SEC No-Action Letter
(available July 2, 1993) (collectively, the "Exchange Offer No-Action Letters"),
PSSA believes that the New Certificates issued pursuant to the Exchange Offer
may be offered for resale, resold or otherwise transferred by holders thereof
(other than a broker-dealer who acquires such New Certificates directly from the
Trust or PSSA for resale pursuant to Rule 144A under the Securities Act or any
other available exemption under the Securities Act or any holder that is an
"affiliate" of PSSA as defined in Rule 405 under the Securities Act), without
compliance with the registration and prospectus delivery provisions of the
Securities Act, provided that such New Certificates are acquired in the ordinary
course of such holders' business and such holders are not engaged in, and do not
intend to engage in, a distribution of such New Certificates and have no
arrangement with any person to participate in a distribution of such New
Certificates. By tendering the Old Certificates in exchange for New
Certificates, each holder, other than a broker-dealer, will represent to the
Trust that: (i) it is not an affiliate of PSSA (as defined in Rule 405 under the
Securities Act) or a broker-dealer tendering Old Certificates acquired directly
from PSSA for its own account; (ii) any New Certificates to be received by it
will be acquired in the ordinary course of its business; and (iii) it is not
engaged in, and does not intend to engage in, a distribution of such New
Certificates and has no arrangement or understanding to participate in a
distribution of the New Certificates. If a holder of Old Certificates is engaged
in or intends to engage in a distribution of the New Certificates or has any
arrangement or understanding with respect to the distribution of the New
Certificates to be acquired pursuant to the Exchange Offer, such holder may not
rely on the applicable interpretations of the staff of the Commission and must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any secondary resale transaction. Each
broker-dealer that receives New Certificates for its own account pursuant to the
Exchange Offer (a "Restricted Broker-Dealer") must acknowledge that it will
deliver a prospectus in connection with any resale of such New Certificates. The
Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a Restricted Broker-Dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a Restricted
Broker-Dealer in connection with resales of New Certificates received in
exchange for Old Certificates where such Old Certificates were acquired by such
Restricted Broker-Dealer as a result of market-making activities or other
trading activities. Pursuant to the Registration Rights Agreement, PSSA has
agreed that starting on the Expiration Date it will make this Prospectus
available to any Restricted Broker-Dealer for use in connection with any such
resale for one year. See "Plan of Distribution".

     Neither the Trust nor PSSA will receive any proceeds from this offering.
PSSA has agreed to pay the expenses of the Exchange Offer. No underwriter or
dealer-manager is being utilized in connection with the Exchange Offer.

     THE EXCHANGE OFFER IS NOT BEING MADE TO, NOR WILL THE TRUST ACCEPT
SURRENDERS FOR EXCHANGE FROM, HOLDERS OF OLD CERTIFICATES IN ANY JURISDICTION IN
WHICH THE EXCHANGE OFFER OR THE ACCEPTANCE THEREOF WOULD NOT BE IN COMPLIANCE
WITH THE SECURITIES AND BLUE SKY LAWS OF SUCH JURISDICTION.

     Prior to this Exchange Offer, there has been no public market for the New
Certificates. Neither PSSA nor the Trust intends to apply for listing of the New
Certificates on any securities exchange or for quotation of the New Certificates
on The Nasdaq Stock Market's National Market or otherwise. Prudential Securities
has previously made a market in the Old Certificates, and the Trust has been
advised that Prudential Securities currently intends to make a market in the New
Certificates, as permitted by applicable laws and regulations, after
consummation of the Exchange Offer. Prudential Securities is not obligated,
however, to make a market in the Old Certificates or the New Certificates and
any such market-making activity may be discontinued at any time without notice
at the sole discretion of Prudential Securities. There can be no assurance as to
the liquidity of the public market for the New Certificates or that any active
public market for the New Certificates will develop or continue. If an active
public market does not develop or continue, the market price and liquidity of
the New Certificates may be adversely affected. See "Risk Factors--Absence of a
Public Market for the New Certificates".

     For a discussion of material risks that should be considered by
participants in the Exchange Offer, see "Risk Factors" beginning on page 9 of

     THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED
UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE
CONTRARY IS A CRIMINAL OFFENSE. 

     THIS PROSPECTUS AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION. HOLDERS OF OLD CERTIFICATES ARE URGED TO READ THIS PROSPECTUS AND
THE RELATED LETTER OF TRANSMITTAL CAREFULLY BEFORE DECIDING WHETHER TO TENDER
THEIR OLD CERTIFICATES PURSUANT TO THE EXCHANGE OFFER.

                    AVAILABLE INFORMATION REGARDING THE TRUST

     PSSA on behalf of the Trust will be subject to the informational
requirements of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), and in accordance therewith will file reports and other information with
the Commission relating to the Trust. Such reports, proxy statements and other
information may be inspected and copied at the following public reference
facilities maintained by the Commission at Room 1024, Judiciary Plaza, 450 Fifth
Street, N.W., Washington, D.C. 20549; Seven World Trade Center, 13th Floor, New
York, New York 10048; and Citicorp Center, 500 West Madison Street, Suite 1400,
Chicago, Illinois 60661. Copies of such material may also be obtained from the
Public Reference Section of the Commission at Room 1024, Judiciary Plaza, 450
Fifth Street, N.W., Washington, D.C. 20549, upon payment of prescribed rates.
The Commission maintains a Web site at http://www.sec.gov containing reports,
proxy statements and other information regarding registrants that file
electronically with the Commission, including PSSA on behalf of the Trust.

     The reports to be filed by PSSA on behalf of the Trust will consist
primarily of distribution date statements relating to the distributions made on
the Trust Certificates and certain material events regarding the Trust, but not
other financial information or statements. The reports will also refer to the
periodic reports filed by NSC so long as NSC is a reporting company under the
Exchange Act. If NSC ceases to be a reporting company under the Exchange Act,
information regarding NSC and the NSC Notes will be limited to that received by
the Trustee, as the holder of the NSC Notes, from the NSC Notes Trustee as
required by the NSC Notes Indenture.

     This Prospectus constitutes a part of a registration statement on Form S-4
(together with all amendments and exhibits, the "Registration Statement") filed
by the Trust and PSSA on behalf of the Trust with the Commission, through the
Electronic Data Gathering, Analysis and Retrieval System ("EDGAR"), under the
Securities Act, with respect to the New Certificates offered hereby. This
Prospectus omits certain of the information contained in the Registration
Statement, and reference is hereby made to the Registration Statement for
further information with respect to the Trust and Holdings and the securities
offered hereby. Although statements concerning and summaries of certain
documents are included herein, reference is made to the copy of such document
filed as an exhibit to the Registration Statement or otherwise filed with the
Commission. These documents may be inspected without charge at the office of the
Commission at Judiciary Plaza, 450 Fifth Street, N.W., Washington, D.C. 20549,
and copies may be obtained at fees and charges prescribed by the Commission.

     No separate financial statements of the Trust have been included or
incorporated by reference herein. PSSA does not believe such financial
statements would be material to holders of the New Certificates because the sole
asset of the Trust consists of debt obligations of an unaffiliated issuer that
is a reporting company under the Exchange Act. See "Description of the Trust
Assets--NSC."

("PSGI"). On April 13, 1998, PSSA deposited $80,000,000 aggregate principal
amount of 7.90% Notes due May 15, 2097 (the "NSC Notes") issued by Norfolk
Southern Corporation ("NSC") with the Trustee in exchange for two classes of
Receipts on Corporate Securities, Series NSC 1998-1: the Amortizing Class
Certificates and the Residual Class Certificates (together the "Trust
Certificates"). The Old Certificates currently constitute, and the New
Certificates along with any Old Certificates not tendered in the Exchange Offer
will constitute, the entire Amortizing Class.

     The Corporate Trust Office of the Trustee is located at 101 Barclay Street,
12th Floor East, New York, New York 10286, Attention: Corporate
Trust--Administration and its number is (212) 815-5098.

                         Description of the Trust Assets

     The assets of the Trust consist solely of $80,000,000 aggregate principal
amount of 7.90% Notes due May 15, 2097 issued by NSC and having the
characteristics described in the NSC Notes Prospectus. The NSC Notes were
originally issued by NSC on or about May 19, 1997 as part of an underwritten
public offering of $350,000,000 aggregate principal amount of such securities
(CUSIP No. 655844AK4) pursuant to a registration statement on Form S-3 (File No.
333-24051) (together with all amendments and exhibits thereto, the "NSC Notes
Registration Statement"), filed by NSC with the Commission under the Securities
Act. Payments of interest are required to be made on the NSC Notes semiannually
on the fifteenth day of each May and November, commencing November 15, 1997, or
if such day is not a business day, on the next business day.

     The NSC Notes deposited in the Trust represent the sole assets of the Trust
that are available to make distributions in respect of the Trust Certificates.
Consequently, the ability of holders of New Certificates to receive cash
distributions in respect of the New Certificates in the event of an Optional
Redemption or a Shortened Maturity Redemption will depend on the Trust's receipt
of payments on, or in respect of, the NSC Notes.

                               The Exchange Offer

The Exchange Offer .........  New Certificates are being offered in exchange for
                              an equal Certificate Principal Balance of Old
                              Certificates. As of the date hereof, Old
                              Certificates with an aggregate Certificate
                              Principal Balance of $68,089,189.08 are
                              outstanding. Old Certificates may be tendered only
                              in minimum denominations of $250,000 and integral
                              multiples of $1.00 in excess thereof.

Registration Rights 
Agreement ................... The Old Certificates were sold on April 13, 1998
                              to Prudential Securities. Prudential Securities
                              placed the Old Certificates with institutional
                              investors in a transaction exempt from
                              registration under the Securities Act in reliance
                              on Rule 144A thereunder. In connection therewith,
                              PSSA and Prudential Securities entered into the
                              Registration Rights Agreement, providing, among
                              other things, for the Exchange Offer to occur. See
                              "The Exchange Offer--Terms of the Exchange Offer".

Resale of New 
Certificates ................ Based on interpretations by the staff of the
                              Commission, as set forth in no-action letters
                              issued to third parties, including the Exchange
                              Offer No-Action Letters, PSSA believes that the
                              New Certificates issued pursuant to the Exchange
                              Offer may be offered for resale, resold or
                              otherwise transferred by holders thereof (other
                              than a broker-dealer who acquires such New
                              Certificates directly from the Trust for resale
                              pursuant to Rule 144A under the Securities Act or
                              any other available exemption under the Securities
                              Act or any holder that is an "affiliate" of PSSA
                              as defined under Rule 405 of the Securities Act),
                              without compliance with the registration and
                              prospectus delivery provisions of the Securities
                              Act, provided that such New Certificates are
                              acquired in the ordinary course of such holders'
                              business and such holders are not engaged in, and
                              do not intend to engage in, a distribution of such
                              New Certificates and have no arrangement with any
                              person to participate in a distribution of such
                              New Certificates. By tendering the Old
                              Certificates in exchange for New Certificates,
                              each holder, other than a broker-dealer, will
                              represent to the Trust that: (i) it is not an
                              affiliate of PSSA (as defined in Rule 405 under
                              the Securities Act) or a broker-dealer tendering
                              Old Certificates acquired directly from PSSA for
                              its own account; (ii) any New Certificates to be
                              received by it were acquired in the ordinary
                              course of its business; and (iii) it is not
                              engaged in, and does not intend to engage in, a
                              distribution of such New Certificates and has no
                              arrangement or understanding to participate in a
                              distribution of the New Certificates. If a holder
                              of Old Certificates is engaged in or intends to
                              engage in a distribution of the New Certificates
                              or has any arrangement or understanding with
                              respect to the distribution of the New
                              Certificates to be acquired pursuant to the
                              Exchange Offer, such holder may not rely on the
                              applicable interpretations of the staff of the
                              Commission and must comply with the registration
                              and prospectus delivery requirements of the
                              Securities Act in connection with any secondary
                              resale transaction. Each Restricted Broker-Dealer
                              that receives New Certificates for its own account
                              pursuant to the Exchange Offer must acknowledge
                              that it will deliver a prospectus in connection
                              with any resale of such New Certificates. The
                              Letter of Transmittal states that by so
                              acknowledging and by delivering a prospectus, a
                              Restricted Broker-Dealer will not be deemed to
                              admit that it is an "underwriter" within the
                              meaning of the Securities Act. This Prospectus, as
                              it may be amended or supplemented from time to
                              time, may be used by a Restricted Broker-Dealer in
                              connection with resales of New Certificates
                              received in exchange for Old Certificates where
                              such Old Certificates were acquired by such
                              Restricted Broker-Dealer as a result of
                              market-making activities or other trading
                              activities. PSSA has agreed that it will make this
                              Prospectus available to any Restricted
                              Broker-Dealer for use in connection with any such
                              resale for one year. See "Plan of Distribution".
                              To comply with the securities laws of certain
                              jurisdictions, it may be necessary to qualify for
                              sale or register the New Certificates prior to
                              offering or selling such New Certificates. PSSA
                              has agreed, pursuant to the Registration Rights
                              Agreement and subject to certain specified
                              limitations therein, to cause the registration or
                              qualification of the New Certificates for offer or
                              sale under the securities or "blue sky" laws of
                              such jurisdictions as may be necessary to permit
                              the holders of New Certificates to trade the New
                              Certificates without any restrictions or
                              limitations under the securities laws of the
                              several states of the United States. 

Consequences of

                              to certain exceptions, holders of Old Certificates
                              who do not exchange their Old Certificates for New
                              Certificates in the Exchange Offer will no longer
                              be entitled to registration rights and will not be
                              able to offer or sell their Old Certificates,
                              unless such Old Certificates are subsequently
                              registered under the Securities Act (which,
                              subject to certain limited exceptions, neither
                              PSSA nor the Trust will have an obligation to do),
                              except pursuant to an exemption from, or in a
                              transaction not subject to, the Securities Act and
                              applicable state securities laws. See "Risk
                              Factors--Risk Factors Relating to the New
                              Certificates and the Exchange Offer--Consequences
                              of Failure to Exchange" and "The Exchange

                              extended, in which case the term "Expiration Date"
                              means the latest date and time to which the

                              the Trust or PSSA in connection with the Exchange

                              purposes. See "U.S. Federal Income Tax
                              Consequences--Exchange of Old Certificates for New
                              Certificates".

Exchange Agent .............. The Bank of New York is serving as exchange agent
                              (the "Exchange Agent") in connection with the
                              Exchange Offer. The Bank of New York is also the
                              Trustee.

Fees and Expenses ........... All expenses incident to the Trust's consummation
                              of the Exchange Offer and compliance with the
                              Registration Rights Agreement will be borne by
                              PSSA. See "The Exchange Offer--Fees and Expenses".

Use of Proceeds ............. There will be no cash proceeds payable to the
                              Trust or PSSA from the issuance of the New
                              Certificates pursuant to the Exchange Offer. The
                              proceeds from the sale of the Old Certificates
                              were applied to the purchase of the NSC Notes and

                              The New Certificates

     The Exchange Offer relates to the exchange of up to $68,089,189.08
aggregate Certificate Principal Balance of Old Certificates for up to an equal
aggregate Certificate Principal Balance of New Certificates. The New
Certificates will be entitled to the benefits of the same Trust Agreement that
governs the Old Certificates and will govern the New Certificates. The form and
terms of the New Certificates are the same in all material respects as the form
and terms of the Old Certificates, except that the New Certificates have been
registered under the Securities Act and therefore will not bear certain legends
restricting the transfer thereof. In addition, as a result of the rating
assigned to the New Certificates, the New Certificates will not be subject to
restrictions on transfer applicable to the Old Certificates pursuant to Rule

"Description of the New Certificates".

Trust Securities ............ The New Certificates (along with any Old
                              Certificates that are not tendered in the Exchange
                              Offer) will constitute the "Amortizing Class
                              Certificates," one of two classes of Trust
                              Certificates, which collectively represent the
                              entire undivided beneficial ownership of the
                              Trust. The current aggregate Certificate Principal
                              Balance of the Amortizing Class Certificates is
                              $68,089,189.08. The other class of Trust
                              Certificates, the Residual Class Certificates, has
                              an $80,000,000 aggregate Certificate Principal
                              Balance. Subject to the occurrence of an Optional
                              Redemption, a Shortened Maturity Redemption, or an
                              In-Kind Distribution, no cash distributions will
                              be made on the Residual Class Certificates.
                              Instead, except in certain circumstances of
                              non-payment by NSC, the Residual Class
                              Certificates outstanding on May 15, 2017 will be
                              terminated and deemed involuntarily surrendered by
                              the holders thereof in exchange for a principal
                              amount of the NSC Notes underlying such Residual
                              Class Certificates equal to the aggregate
                              Certificate Principal Balance of the Residual
                              Class Certificates. 

Scheduled Distributions 
on New Certificates. ........ Scheduled distributions on the Amortizing Class
                              Certificates will consist of equal semiannual
                              installments allocable to principal and interest
                              through May 15, 2017 (each, a "Fixed Payment").
                              Each Fixed Payment will be allocated between
                              interest accrued at a per annum rate equal to
                              6.375% compounded semiannually (the "Yield to
                              Amortizing Class Final Distribution Date") on the
                              then-outstanding Certificate Principal Balance of
                              the Amortizing Class Certificates, and the
                              repayment of principal. Although payments on the
                              Amortizing Class Certificates are denominated as
                              principal and interest, the Amortizing Class
                              Certificates generally represent indirect
                              beneficial ownership of solely the interest
                              payments on the NSC Notes on or before May 15,
                              2017 and will be paid solely from interest
                              payments on the NSC Notes; absent an Optional
                              Redemption, a Shortened Maturity Redemption, or an
                              In-Kind Distribution on or prior to May 15, 2017,
                              the Amortizing Class Certificateholders have no
                              right to any portion of the principal payments on
                              the NSC Notes. The Amortizing Class Certificates
                              are scheduled to be paid in full on May 15, 2017
                              (the "Amortizing Class Final Distribution Date").
                              The actual final payment date could occur later in
                              the event of a payment default on the NSC Notes,
                              and could occur earlier in the case of an Optional
                              Redemption, a Shortened Maturity Redemption, or an
                              In-Kind Distribution. 

Optional Redemption ......... The NSC Notes will be redeemable prior to
                              maturity, as a whole or in part, at the option of
                              NSC (an "Optional Redemption"), upon not less than
                              30 nor more than 60 days' prior written notice, at
                              any time, at a redemption price equal to the
                              greater of (i) 100% of the principal amount being
                              redeemed and (ii) the sum of the present values of
                              the remaining scheduled payments of principal and
                              interest thereon discounted to the date of
                              redemption (an "Optional Redemption Date") on a
                              semiannual basis at the Treasury Yield (as defined
                              herein) plus 20 basis points, together with
                              accrued interest to the date of redemption. In the
                              event of an Optional Redemption, the Trustee will
                              distribute the payment received on the NSC Notes
                              on the Optional Redemption Date to the holders of
                              the Amortizing Class Certificates and the Residual
                              Class Certificates, respectively, in the same
                              ratio as (i) the present value of all originally
                              scheduled future payments on the Amortizing Class
                              Certificates bears to (ii) the present value of
                              all originally scheduled future payments on the
                              NSC Notes after May 15, 2017, discounted
                              semiannually in each case at a rate of 7.90% per
                              annum (such ratio being the "Distribution Ratio")
                              to the Optional Redemption Date. Such ratio will
                              be calculated by the Company, as calculation agent
                              (the "Calculation Agent"). In the case of an
                              Optional Redemption of less than all of the NSC
                              Notes, the Trustee will distribute the payment
                              received on the NSC Notes on the Optional
                              Redemption Date to the holders of the Amortizing
                              Class Certificates and the Residual Class
                              Certificates on the basis of the Distribution
                              Ratio as of the Optional Redemption Date on a pro
                              rata basis; such a distribution will result in a
                              reduction (based on the percentage of NSC Notes
                              redeemed) of the Residual Class Certificates
                              Certificate Principal Balance and a recalculation
                              of the Certificate Principal Balance of, and Fixed
                              Payments with respect to, the Amortizing Class
                              Certificates based on the remaining NSC Notes
                              after such redemption.

Shortened Maturity 
Redemption .................. Upon the occurrence of a Tax Event (as defined
                              below) with respect to the NSC Notes, NSC has the
                              right to shorten the maturity of the NSC Notes (i)
                              to the minimum extent required, in the opinion of
                              nationally recognized independent tax counsel,
                              such that, after the shortening of the maturity,
                              interest paid on the NSC Notes will be
                              deductible for U.S. federal income tax purposes
                              or, (ii) if such counsel is unable to opine
                              definitively as to such minimum period, the
                              minimum extent so required as determined in good
                              faith by the Board of Directors of NSC after
                              receipt of an opinion of such counsel regarding
                              the applicable legal standards. (Any such new
                              maturity date is referred to herein as the
                              "Shortened Maturity Date.") If the Shortened
                              Maturity Date is on or prior to May 15, 2017, the
                              Amortizing Class Certificates and the Residual
                              Class Certificates will be redeemed on the
                              Shortened Maturity Date (a "Shortened Maturity
                              Redemption"). The Trustee will distribute the
                              payment received on the NSC Notes on the Shortened
                              Maturity Date to the holders of each class of
                              Certificates on the basis of the Distribution
                              Ratio as of the Shortened Maturity Date. Such
                              ratio will be calculated by the Calculation Agent.
                              After such a distribution, holders of Amortizing
                              Class Certificates and Residual Class Certificates
                              will receive no further distributions from the
                              Trust. A Shortened Maturity Redemption as a result
                              of a Tax Event may increase the amount of original
                              issue discount required to be included in a
                              holder's ordinary gross income. See "U.S. Federal
                              Income Tax Consequences--Purchase and Holding of
                              Trust Certificates."

                              A "Tax Event" means that NSC shall have received
                              an opinion of nationally recognized independent
                              tax counsel to the effect that, as a result of (a)
                              any amendment to, clarification of, or change
                              (including any announced prospective amendment,
                              clarification or change) in any law, or any
                              regulation thereunder, of the United States, (b)
                              any judicial decision, official administrative
                              pronouncement, ruling, regulatory procedure or
                              regulation, including any notice or announcement
                              of intent to adopt or promulgate any ruling,
                              regulatory procedure or regulation (any of the
                              foregoing, an "Administrative or Judicial
                              Action"), or (c) any amendment to, clarification
                              of, or change in any official position with
                              respect to, or any interpretation of, an
                              Administrative or Judicial Action or a law or
                              regulation of the United States that differs from
                              the theretofore generally accepted position or
                              interpretation, in each case, occurring on or
                              after May 19, 1997, there is more than an
                              insubstantial increase in the risk that interest
                              paid by NSC on the NSC Notes is not, or will not
                              be, deductible, in whole or in part, by NSC for
                              United States federal income tax purposes. See
                              "Description of the New Certificates--Shortened
                              Maturity Redemption".

In-Kind Distribution ........ Upon a Payment Default or an Acceleration of the
                              NSC Notes under the terms of the trust indenture
                              relating to the NSC Notes (the "NSC Notes
                              Indenture") on or before May 15, 2017, the Trustee
                              will make an In-Kind Distribution of the NSC Notes
                              to the holders of the Trust Certificates. Such
                              distribution will be made to the holders of the
                              Residual Class Certificates and the Amortizing
                              Class Certificates, respectively, in the same
                              ratio as (i) the present value of all originally
                              scheduled future payments on the NSC Notes after
                              May 15, 2017 bears to (ii) the present value of
                              all originally scheduled future payments on the
                              Amortizing Class Certificates, discounted
                              semiannually in each case at a rate of 7.90% per
                              annum to the date of such Payment Default or
                              Acceleration. Such ratio will be calculated by the
                              Calculation Agent. See "Description of New
                              Certificates--In-Kind Distribution". After such a
                              distribution, Holders of Amortizing Class
                              Certificates will receive no further distributions
                              from the Trust. An In-Kind Distribution may be
                              treated in whole or in part as equivalent to a
                              taxable sale or exchange. See "U.S. Federal Income
                              Tax Consequences--Distributions".

Certificateholder 
Exchange Right .............. Holders of both the Amortizing Class Certificates
                              and Residual Class Certificates will have the
                              right on any Scheduled Distribution Date other
                              than May 15, 2017, on not less than 30 and not
                              more than 45 days' prior written notice to the
                              Trustee, to exchange Certificates of both Classes
                              representing not less than 10 percent of the
                              Aggregate Certificate Principal Balance of all
                              Certificates of such Class for an equivalent
                              percentage of NSC Notes held in the Trust. See
                              "Description of New Certificates--Exchange of
                              Certificates for NSC Notes." 

Record Dates ................ The fifth day immediately preceding each
                              Distribution Date.

Denominations ............... The New Certificates will be denominated and
                              payable in U.S. dollars and will be issued in
                              definitive, fully-registered form in minimum
                              denominations of $250,000 Certificate Principal
                              Balance and integral multiples of $1.00 in excess
                              thereof.

Federal Income Tax 
Consequences ................ For U.S. federal income tax purposes, the Trust
                              will not be treated as an association taxable as a
                              corporation (or a publicly traded partnership
                              treated as an association). Although the
                              characterization of the Trust is not certain, the
                              Trust should be treated for U.S. federal income
                              tax purposes as a grantor trust, and the Trustee
                              intends to report income, gain, loss and
                              deductions to the Internal Revenue Service on that
                              basis. If the Trust were not classified as a
                              grantor trust, it would be classified as a
                              partnership. In either event, the Trust will not
                              be subject to U.S. federal income taxation.

                              Under the grantor trust characterization, each
                              holder of a Trust Certificate will be treated as
                              owning the rights to those payments on the NSC
                              Notes that are allocable to that Trust Certificate
                              and will be taxed under the "stripped bond" rules
                              of the Internal Revenue Code of 1986. Under those
                              rules, a holder of a Trust Certificate will be
                              required to include in ordinary gross income
                              original issue discount income based on the
                              holder's yield to maturity for the Trust
                              Certificate.

                              The exchange of New Certificates for Old
                              Certificates will not be a sale or exchange or
                              otherwise a taxable event for Federal income tax
                              purposes. See "U.S. Federal Income Tax
                              Consequences--Exchange of Old Certificates for New
                              Certificates".

Ratings ..................... The New Certificates will be rated "Baa1" by
                              Moody's Investors Service, Inc. and "BBB+" by
                              Standard & Poor's Ratings Services at issuance. A
                              security rating is not a recommendation to buy,
                              sell or hold securities and may be subject to
                              revision or withdrawal at any time by the
                              assigning rating organization.

                                  RISK FACTORS

     Prior to tendering Old Certificates in the Exchange Offer, holders of Old
Certificates should carefully review the information contained and incorporated
by reference in this Prospectus and should particularly consider the following
matters.

Limited Obligations and Interests

     The New Certificates will not represent an obligation of, or interest in,
PSSA or any of its affiliates. The New Certificates will not be insured or
guaranteed by any government agency or instrumentality, PSSA, any Person
affiliated with PSSA or the Trustee, or any other Person.

No Detailed Information About NSC or the NSC Notes

     This Prospectus provides limited information with respect to the NSC Notes
and NSC, any risk factors relating thereto, and any rights or obligations,
legal, financial or otherwise, arising under or related to the NSC Notes. See
"Description of the Trust Assets".

Events of Default

     If an event of default on the NSC Notes occurs, the risk of loss with
respect to the NSC Notes lies entirely with the holders of the Trust
Certificates. If a Payment Default or Acceleration occurs with respect to the
NSC Notes, the Trustee will distribute the NSC Notes to the holders of the Trust
Certificates in an In-Kind Distribution. In connection with an In-Kind
Distribution, a holder will recognize gain or loss on such exchange equal to the
difference between the portion of the amount realized on the exchange allocable
to the holder and the allocable portion of the holder's basis in the
Certificate. See "Description of the New Certificates--Distribution of the NSC
Notes on Payment Default or Acceleration" herein. An In-Kind Distribution may be
treated in whole or in part as equivalent to a taxable sale or exchange. See
"U.S. Federal Income Tax Consequences--Distributions".

Bankruptcy Risks

     The New Certificates are payable solely from payments made on the NSC Notes
by NSC. NSC is subject to laws permitting bankruptcy, moratorium, reorganization
or other actions which, in the event of financial difficulties of NSC, could
result in delays in distribution, partial distribution or non-distribution, on
the New Certificates. See "Description of the New Certificates--Distribution of
the NSC Notes on Payment Default or Acceleration" herein.

Maturity and Redemption Considerations

     The Amortizing Class Certificates are scheduled to receive semiannual
distributions as described in "Description of the New Certificates--Collections
and Distributions on New Certificates." Potentially, the maturity and yield of
the New Certificates could be affected by (i) a cash distribution to holders of
the Trust Certificates upon a Shortened Maturity Redemption or an Optional
Redemption of the NSC Notes or (ii) a distribution of the NSC Notes to such
holders upon an In-Kind Distribution. In the event of a cash distribution on a
Shortened Maturity Date or an Optional Redemption Date, holders of Trust
Certificates will receive their respective shares (determined pursuant to
formulas described in "Description of the New Certificates--Shortened Maturity
Redemption" and "Description of the New Certificates--Optional Redemption") of
the redemption price (which price will consist of principal and accrued and
unpaid interest, without premium); holders may then need to reinvest at the
then-prevailing market rates rather than receiving a fixed-rate coupon of 7.90
percent per annum for the period remaining prior to May 15, 2017. A Shortened
Maturity Redemption as a result of a Tax Event may increase the amount of
original issue discount required to be included in a holder's ordinary gross
income. See "U.S. Federal Income Tax Consequences--Purchase and Holding of Trust
Certificates." In the event of an In-Kind Distribution, holders of New
Certificates will receive their share of the NSC Notes (determined pursuant to a
formula described in "Description of the New Certificates--Distribution of the
NSC Notes on Payment Default or Acceleration") at the time of such distribution.
An In-Kind Distribution may be treated in whole or in part as equivalent to a
taxable sale or exchange. See "U.S. Federal Income Tax
Consequences--Distributions".

Passive Nature of the Trust

     The Trustee with respect to the Trust Certificates will hold the NSC Notes
for the benefit of the holders of the Trust Certificates. The Trust will
generally hold the NSC Notes to maturity and not dispose of them, regardless of
adverse events, financial or otherwise, which may affect NSC or the value of the
NSC Notes, except pursuant to an In-Kind Distribution to holders of the Trust
Certificates in exchange for their Trust Certificates.

Risk Factors Relating to the Certificates and the Exchange Offer

Consequences of Failure to Exchange

     Holders of Old Certificates who do not exchange their Old Certificates for
New Certificates pursuant to the Exchange Offer will continue to be subject to
the restrictions on transfer of such Old Certificates as set forth in the legend
thereon as a consequence of the issuance of the Old Certificates pursuant to
exemptions from, or in transactions not subject to, the registration
requirements of the Securities Act and applicable state securities laws. In
addition, the Old Certificates will remain subject to the transfer restrictions
described therein pursuant to Rule 3a-7. In general, the Old Certificates may
not be offered or sold, unless registered under the Securities Act, except
pursuant to an exemption from, or in a transaction not subject to, the
Securities Act and applicable state securities laws. PSSA does not currently
anticipate that it will register the Old Certificates under the Securities Act.
To the extent that Old Certificates are tendered and accepted in the Exchange
Offer, the trading market for Old Certificates could be adversely affected.

Absence of a Public Market for the New Certificates

     Prior to the Exchange Offer, there has been no public market for the New
Certificates and it is uncertain whether such a market will develop. Neither
PSSA nor the Trust intends to apply for listing of the New Certificates on any
securities exchange or for quotation of the New Certificates on The Nasdaq Stock
Market's National Market or otherwise. The Trust has been advised by Prudential
Securities that it currently intends to make a market in the New Certificates,
as permitted by applicable laws and regulations, after consummation of the
Exchange Offer. Prudential Securities is not obligated, however, to make a
market in the New Certificates, and any such market-making activity may be
discontinued at any time without notice at the sole discretion of Prudential
Securities. There can be no assurance as to the liquidity of the market for the
New Certificates or that any active market for the New Certificates will develop
or continue. If an active market does not develop or continue, the market price
and liquidity of the New Certificates may be adversely affected.

                                 USE OF PROCEEDS

     There will be no cash proceeds payable to PSSA or the Trust from the
issuance of the New Certificates pursuant to the Exchange Offer. PSSA sold the
Old Certificates to Prudential Securities, an affiliate of PSSA, as initial
purchaser. The proceeds from the sale of the Old Certificates were received by
PSSA and were applied to its purchase of the NSC Notes, which, after the
purchase thereof, were deposited by PSSA in the Trust. PSSA also paid the
issuance costs out of the proceeds from the sale of Old Certificates.

                             FORMATION OF THE TRUST

     Receipts on Corporate Securities Trust, Series NSC 1998-1 was formed under
New York law pursuant to the Trust Agreement dated as of August 28, 1997, as
amended by Base Amendment No. 1 dated as of February 27, 1998 and as
supplemented by the Series NSC 1998-1 Supplement dated as of April 13, 1998.
Concurrently with the execution and delivery of the Trust Certificates, PSSA
deposited the NSC Notes with the Trustee. The Trustee, on behalf of the Trust,
accepted the NSC Notes and delivered the Trust Certificates to PSSA. The Trustee
is holding the NSC Notes for the benefit of the holders of the Trust
Certificates.

                         DESCRIPTION OF THE TRUST ASSETS

     The assets of the Trust consist solely of $80,000,000 aggregate principal
amount of 7.90% Notes due May 15, 2097 issued by NSC and having the
characteristics described in the NSC Notes Prospectus. The NSC Notes were
originally issued by NSC on or about May 19, 1997 as part of an underwritten
public offering of $350,000,000 aggregate principal amount of such securities
(CUSIP No. 655844AK4) pursuant to a registration statement on Form S-3 (File No.
333-24051) (together with all amendments and exhibits thereto, the "NSC Notes
Registration Statement"), filed by NSC with the Commission under the Securities
Act. Payments of interest are required to be made on the NSC Notes semiannually
on the fifteenth day of each May and November, commencing November 15, 1997, or
if such day is not a business day, on the next business day.

     The NSC Notes deposited in the Trust represent the sole assets of the Trust
that are available to make distributions in respect of the Trust Certificates.
Consequently, the ability of holders of New Certificates to receive cash
distributions in respect of the New Certificates in the event of an Optional
Redemption or a Shortened Maturity Redemption will depend on the Trust's receipt
of payments on, or in respect of, the NSC Notes.

     Holders of New Certificates have no rights with respect to the NSC Notes
except in the event of an In-Kind Distribution.

     The NSC Notes Prospectus states that the NSC Notes rank pari passu with all
other unsecured and unsubordinated indebtedness of NSC. Under the NSC Notes
Indenture, the events of default are as follows: (a) failure to pay principal of
or any premium on any NSC Note when due; (b) failure to pay any interest on any
NSC Note when due, continued for 30 days; (c) failure to perform any other
covenant or warranty of NSC in the NSC Notes Indenture with respect to the NSC
Notes, continued for 90 days after written notice, as provided in the NSC Notes
Indenture; (d) acceleration of the NSC Notes or any other indebtedness for
borrowed money, in an aggregate principal amount exceeding $30,000,000, of NSC
or any Significant Subsidiary (within the meaning of the federal securities
laws) under the terms of the instrument or instruments under which such
indebtedness is issued or secured, if such acceleration is not annulled, or such
indebtedness is not discharged, or a sum of money sufficient to discharge in
full such indebtedness is not deposited in trust, within 10 days after written
notice as provided in the NSC Notes Indenture, and (e) certain events in
bankruptcy, insolvency or reorganization.

     The NSC Notes are not subject to a sinking fund. The NSC Notes may be
redeemed, in whole or in part, at any time at the option of NSC. See
"Description of the Trust Assets--Optional Redemption."

     The NSC Notes are denominated in United States dollars and issued in fully
registered form without coupons in denominations of $1,000 and any integral
multiples thereof. The NSC Notes were issued in book-entry form only and are
held through participants in the Depository Trust Company.

Optional Redemption

     The NSC Notes will be redeemable prior to maturity, as a whole or in part,
at the option of NSC (an "Optional Redemption"), upon not less than 30 nor more
than 60 days' prior written notice, at any time, at a redemption price equal to
the greater of (i) 100% of the principal amount being redeemed and (ii) the sum
of the present values of the remaining scheduled payments of principal and
interest thereon discounted to the date of redemption (an "Optional Redemption
Date") on a semiannual basis at the Treasury Yield (as defined below) plus 20
basis points, together with accrued interest to the date of redemption. In the
event of an Optional Redemption, the Trustee will distribute the payment
received on the NSC Notes on the Optional Redemption Date to the holders of the
Amortizing Class Certificates and the Residual Class Certificates, respectively,
in the same ratio as (i) the present value of all originally scheduled future
payments on the Amortizing Class Certificates bears to (ii) the present value of
all originally scheduled future payments on the NSC Notes after May 15, 2017,
discounted semiannually in each case at a rate of 7.90% per annum (such ratio
being the "Distribution Ratio") to the Optional Redemption Date. Such ratio will
be calculated by the Company, as calculation agent (the "Calculation Agent"). In
the case of such an Optional Redemption of less than all of the NSC Notes, the
Trustee will distribute the payment received on the NSC Notes on the Optional
Redemption Date to the holders of the Amortizing Class Certificates and the
Residual Class Certificates on the basis of the Distribution Ratio as of the
Optional Redemption Date on a pro rata basis; such a distribution will result in
a reduction (based on the percentage of NSC Notes redeemed) of the Residual
Class Certificates Certificate Principal Balance and a recalculation of the
Certificate Principal Balance of, and Fixed Payments with respect to, the
Amortizing Class Certificates based on the remaining NSC Notes after such
redemption.

     "Treasury Yield" means, with respect to any redemption date, the rate per
annum equal to the semi-annual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price of the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such redemption date.

     "Comparable Treasury Issue" means the United States Treasury security
selected by the Independent Investment Banker as having a maturity most
comparable to the remaining term of the NSC Notes, that would be utilized, at
the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of the NSC Notes.

     "Independent Investment Banker" means J.P. Morgan Securities Inc. or
Merrill Lynch, Pierce, Fenner & Smith Incorporated or, if either such firm is
unwilling or unable to select the Comparable Treasury Issue, an independent
investment banking institution of national standing in the United States
appointed by the Senior Trustee after consultation with the Corporation.

     "Comparable Treasury Price" means, with respect to any redemption date, (i)
the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
business day preceding such redemption date, as set forth in the daily
statistical release (or any successor release) published by the Federal Reserve
Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S.
Government Securities" or (ii) if such release (or any successor release) is not
published or does not contain such prices on such business day, the average of
the Reference Treasury Dealer Quotations for such redemption date. "Reference
Treasury Dealer Quotations" means, with respect to each Reference Treasury
Dealer and any redemption date, the average, as determined by the Trustee, of
the bid and asked prices for the Comparable Treasury Issue (expressed in each
case as a percentage of its principal amount) quoted in writing to the Trustee
by such Reference Treasury Dealer at 5:00 p.m., New York, New York time, on the
third business day preceding such redemption date.

     "Reference Treasury Dealer" means each of J.P. Morgan Securities Inc. and
Merrill Lynch Government Securities Inc. and their respective successors;
provided, however, that if one of the foregoing ceases to be a primary U.S.
Government securities dealer in New York, New York (a "Primary Treasury Dealer")
or otherwise fails to provide a Reference Treasury Dealer Quotation, NSC will
substitute therefor another Primary Treasury Dealer.

Shortened Maturity Redemption

     The NSC Notes Prospectus states as follows: NSC intends to deduct interest
paid on the NSC Notes for United States federal income tax purposes. The Clinton
Administration's budget proposal for Fiscal Year 1998, however, which was
released on February 6, 1997, contains a series of proposed tax law changes
that, if enacted, would prohibit an issuer from deducting interest payments on
debt instruments that have a maturity of more than 40 years, such as the NSC
Notes described herein. The Administration's proposal specifies that the changes
would be effective for debt instruments issued on or after the date of the first
Congressional Committee action. There can be no assurance that legislation
affecting NSC's ability to deduct interest paid on the NSC Notes will not be
enacted in the future or that any such legislation would not be effective
retroactively.

      The NSC Notes Prospectus states as follows: Upon the occurrence of a Tax
Event (as defined below), NSC will have the right, without the consent of the
holders of the NSC Notes, to shorten the maturity of the NSC Notes to the
minimum extent required, in the opinion of nationally recognized independent tax
counsel to NSC, such that, after the shortening of the maturity, interest paid
on the NSC Notes will be deductible for United States federal income tax
purposes or, if such counsel is unable to opine definitively as to such minimum
period, the minimum extent so required as determined in good faith by the Board
of Directors of NSC, after receipt of an opinion of such counsel regarding
applicable legal standards. There can be no assurance that the NSC would not
exercise its right to shorten the maturity of the NSC Notes upon the occurrence
of such a Tax Event and no assurance as to the period by which such maturity
would be shortened.

     The NSC Notes Prospectus states as follows: In the event that NSC elects to
exercise its right to shorten the maturity of NSC Notes upon the occurrence of a
Tax Event, NSC will mail a notice of shortened maturity to each holder of the
NSC Notes by first-class mail not more than 60 days after the occurrence of such
Tax Event, stating the new maturity date of the NSC Notes. Such notice shall be
effective immediately upon mailing.

     The NSC Notes Prospectus states as follows: NSC believes that the NSC Notes
should constitute indebtedness for United States federal income tax purposes
under current law and, in that case, an exercise of its right to shorten the
maturity of the NSC Notes would not be a taxable event to holders for such
purposes. Prospective investors should be aware, however, that NSC's exercise of
its right to shorten the maturity of the NSC Notes would be a taxable event to
holders for United States federal income tax purposes if the NSC Notes are
treated as equity for such purposes before the maturity is shortened and the NSC
Notes of shortened maturity are treated as debt for such purposes.

NSC Notes Indenture

     The NSC Notes were issued under the NSC Notes Indenture, dated January 15,
1991, as amended or supplemented, between NSC and First Trust of New York, N.A.,
as trustee.

Modification, Amendment and Waiver

     The NSC Notes Prospectus states as follows: Modifications and amendments of
the NSC Notes Indenture may be made by NSC and the NSC Notes Trustee with the
consent of the holders of a majority in aggregate principal amount of the debt
securities of each series affected by such modification amendment; provided,
however, that no such modification or amendment may, without the consent of the
holder of each debt security affected thereby, (1) change the stated maturity
date of the principal of, or any installment of principal of, premium, if any,
or interest, if any, on, any debt security, (2) reduce the principal, premium,
if any, and/or interest, if any, on, any debt security, (3) reduce the amount of
principal on an original issue discount debt security payable on acceleration of
the maturity thereof, (4) change the place or currency of payment of principal,
premium, if any, and/or interest, if any, on any debt security, (5) impair the
right to institute suit for the enforcement of any payment on or with respect to
any debt security, (6) reduce the percentage in principal amount of debt
securities of any series, the consent of the holders of which is required for
modification or amendment of the NSC Notes Indenture or for waiver of certain
defaults, (7) modify the conversion provisions applicable to convertible debt
securities in a manner adverse to the holders thereof or (8) modify the
subordination provisions applicable to any series of debt securities in a manner
adverse to the holders thereof.

     The NSC Notes Prospectus states as follows: The holders of a majority in
aggregate principal amount of the debt securities of each series may, on behalf
of all holders of debt securities of that series, waive, insofar as that series
is concerned, compliance by NSC with certain restrictive provisions of the NSC
Notes Indenture. The holders of a majority in aggregate principal amount of the
debt securities of each series may, on behalf of all holders of debt securities
of that series, waive any past default under the applicable NSC Notes Indenture
with respect to debt securities of that series, except (1) a default in the
payment of principal, premium, if any, and/or interest, if any, on any debt
security of such series and (2) in respect of a covenant or provision of the NSC
Notes Indenture which cannot be modified or amended without the consent of the
holder of each debt security of such series affected.

     The information under this caption is derived solely from the description
of the NSC Notes contained in the NSC Notes Prospectus. An investor may wish to
read this Prospectus in conjunction with (i) the NSC Notes Prospectus and (ii)
the NSC Notes Registration Statement, of which the NSC Notes Prospectus is a
part. This Prospectus relates only to New Certificates offered hereby and does
not relate to an offering of the NSC Notes. No representation is made by the
Trust, the Trustee or PSSA as to the accuracy or completeness of the information
contained in the NSC Notes Prospectus or the NSC Notes Registration Statement.

NSC

     This Prospectus does not provide information with respect to NSC. No
investigation has been made of the financial condition or creditworthiness of
NSC or any of its subsidiaries in connection with the issuance of the New
Certificates. PSSA is not an affiliate of NSC. Prospective purchasers of the New
Certificates should consider carefully NSC's financial condition and its ability
to make payments in respect of the NSC Notes. All information contained in this
Prospectus regarding NSC is derived from the NSC Notes Prospectus. Neither PSSA
nor the Trust nor any of their respective affiliates has participated in the
preparation of the NSC Notes Prospectus or the NSC Notes Registration Statement,
and takes no responsibility for the accuracy or completeness of the information
provided therein.

     NSC is presently subject to the informational requirements of the Exchange
Act, and in accordance therewith files reports and other information (including
financial information) with the Commission. Copies of such reports and other
information may be inspected and copied at the public reference facilities
maintained by the Commission at 450 Fifth Street, N.W., Room 1024, Washington,
D.C. 20549; Seven World Trade Center, Suite 1300, New York, New York 10048; and
Northwestern Atrium Center, 500 West Madison Street, Suite 1400, Chicago,
Illinois 60661, and may be obtained from the Public Reference Section of the
Commission at Washington, D.C. 20549, at prescribed rates. The Commission
maintains a Web site at http://www.sec.gov containing reports, proxy statements
and other information regarding registrants that file electronically with the
Commission. In addition, certain material described above and other information
will also be available for inspection at the offices of the New York Stock
Exchange at 20 Broad Street, New York, New York. Neither PSSA nor the Trust nor
any of their respective affiliates has participated in the preparation of any of
the foregoing reports or other information filed by NSC with the Commission or
the New York Stock Exchange or has made any investigation with respect to the
information contained therein.

     If NSC ceases to be a reporting company under the Exchange Act, information
regarding NSC or the NSC Notes will be limited to any information received by
the Trustee, as the holder of the NSC Notes, pursuant to the NSC Notes Indenture
from NSC or the trustee under the NSC Notes Indenture (the "NSC Notes Trustee").
The Trustee will furnish such information to registered holders of the Trust
Certificates promptly following receipt.

     The Trust will have no assets other than the NSC Notes from which to make
distributions of amounts due in respect of the Trust Certificates. Consequently,
the ability of holders of Trust Certificates to receive distributions and the
timeliness of such distributions in respect of the New Certificates will depend
on the Trust's receipt of payments on the NSC Notes from NSC.

Ratings

     The NSC Notes have been rated "Baa1" and "BBB+" by Moody's Investors
Service, Inc. and Standard & Poor's Ratings Services, respectively. The New
Certificates will be rated "Baa1" by Moody's Investors Service, Inc. and "BBB+"
by Standard & Poor's Ratings Services at issuance. Any rating of the NSC Notes
or the New Certificates is not a recommendation to purchase, hold or sell the
New Certificates, and there can be no assurance that a rating will remain for
any given period of time or that a rating will not be revised or withdrawn
entirely by a rating agency if in its judgment circumstances in the future so
warrant.

Prudential Securities and NSC

     From time to time, Prudential Securities may be engaged by NSC as an
underwriter or placement agent, in an advisory capacity or in other business
arrangements. In addition, Prudential Securities or another affiliate of PSSA
may make a market in other outstanding securities of NSC.

The Exchange Offer being made hereby, if commenced and consummated within the
time periods described in this paragraph, will satisfy those requirements under
the Registration Rights Agreement.

     Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal (which together constitute the Exchange Offer),
all Old Certificates validly tendered and not withdrawn prior to 5:00 p.m., New
York City time, on the Expiration Date will be accepted for exchange. New
Certificates of the same class will be issued in exchange for an equal principal
amount of outstanding Old Certificates accepted in the Exchange Offer. Old
Certificates may be tendered only in minimum denominations of $250,000
Certificate Principal Balance and integral multiples of $1.00 in excess thereof.
This Prospectus, together with the Letter of Transmittal, is being sent to all
registered holders as of January , 1999. The Exchange Offer is not conditioned
upon any minimum principal amount of Old Certificates being tendered in
exchange. However, the obligation to accept Old Certificates for exchange
pursuant to the Exchange Offer is subject to certain conditions as set forth
herein under "--Conditions".

     Old Certificates shall be deemed to have been accepted as validly tendered
when, as and if the Trustee has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
of Old Certificates for the purposes of receiving the New Certificates and
delivering New Certificates to such holders.

     Based on interpretations by the staff of the Commission, as set forth in
no-action letters issued to third parties, including the Exchange Offer
No-Action Letters, PSSA believes that the New Certificates issued pursuant to
the Exchange Offer may be offered for resale, resold or otherwise transferred by
holders thereof (other than a broker-dealer who acquires such New Certificates
directly from PSSA for resale pursuant to Rule 144A under the Securities Act or
any other available exemption under the Securities Act or any holder that is an
"affiliate" of PSSA as defined in Rule 405 under the Securities Act), without
compliance with the registration and prospectus delivery provisions of the
Securities Act, provided that such New Certificates are acquired in the ordinary
course of such holders' business and such holders are not engaged in, and do not
intend to engage in, a distribution of such New Certificates and have no
arrangement with any person to participate in a distribution of such New
Certificates. By tendering the Old Certificates in exchange for New
Certificates, each holder, other than a broker-dealer, will represent to the
Trust that (i) it is not an affiliate of PSSA (as defined in Rule 405 under the
Securities Act) or a broker-dealer tendering Old Certificates acquired directly
from the Trust or PSSA for its own account; (ii) any New Certificates to be
received by it will be acquired in the ordinary course of its business; and
(iii) it is not engaged in, and does not intend to engage in, a distribution of
such New Certificates and has no arrangement or understanding to participate in
a distribution of the New Certificates. If a holder of Old Certificates is
engaged in or intends to engage in a distribution of the New Certificates or has
any arrangement or understanding with respect to the distribution of the New
Certificates to be acquired pursuant to the Exchange Offer, such holder may not
rely on the applicable interpretations of the staff of the Commission and must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any secondary resale transaction. Each
Broker-Dealer that receives New Certificates for its own account ("Restricted
Broker-Dealer") pursuant to the Exchange Offer must acknowledge that it will
deliver a prospectus in connection with any resale of such New Certificates. The
Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a Restricted Broker-Dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a Restricted
Broker-Dealer in connection with resales of New Certificates received in
exchange for Old Certificates where such Old Certificates were acquired by such
Restricted Broker-Dealer as a result of market-making activities or other
trading activities. PSSA has agreed that for a period of one year it will cause
this Prospectus to be made available to any Restricted Broker-Dealer for use in
connection with any such resale. See "Plan of Distribution".

     If (i) PSSA is not required to file an Exchange Offer Registration
Statement with respect to the New Certificates because the Exchange Offer is not
permitted by applicable law or (ii) if any holder of Old Certificates shall
notify PSSA within 20 Business Days following the consummation of the Exchange
Offer that (A) such holder was prohibited by law or Commission policy from
participating in the Exchange Offer or (B) such holder may not resell the
Exchange Certificates acquired by it in the Exchange Offer to the public without
delivering a prospectus and the prospectus contained in the Exchange Offer
Registration Statement is not appropriate or available for such resales by such
holder or (C) such holder is a Broker-Dealer and holds Old Certificates acquired
directly from any of the Trust or PSSA or one of their respective Affiliates,
then PSSA shall (x) cause to be filed, on or prior to 60 days after the date on
which PSSA determines that it is not required to file the Exchange Offer
Registration Statement pursuant to clause (i) above, or 60 days after the date
on which PSSA receives the notice specified in clause (ii) above, a shelf
registration statement pursuant to Rule 415 under the Securities Act (which may
be an amendment to the Exchange Offer Registration Statement (in either event,
the "Shelf Registration Statement") relating to all Old Certificates the holders
of which shall have provided the information required by the Registration Rights
Agreement, and shall (y) use its best efforts to cause such Shelf Registration
Statement to become effective on or prior to 190 days after the date on which
PSSA becomes obligated to file such Shelf Registration Statement. PSSA shall use
its best efforts to keep the Shelf Registration Statement continuously
effective, supplemented and amended to the extent necessary to ensure that it is
available for sales of Old Certificates by the holders thereof entitled to the
benefit of the Shelf Registration Statement, and to ensure that it conforms with
the requirements of the Registration Rights Agreement, the Securities Act and
the policies, rules and regulations of the Commission as announced from time to
time, for a period of not more than one year following the date on which such
Shelf Registration Statement first becomes effective under the Securities Act or
such shorter period that will terminate when all the Old Certificates covered by
the Shelf Registration Statement have been sold pursuant to the Shelf
Registration Statement.

     Upon consummation of the Exchange Offer, subject to certain exceptions,
holders of Old Certificates who do not exchange their Old Certificates for New
Certificates in the Exchange Offer will no longer be entitled to registration
rights and will not be able to offer or sell their Old Certificates, unless such
Old Certificates are subsequently registered under the Securities Act (which,
subject to certain limited exceptions, PSSA will have no obligation to do),
except pursuant to an exemption from, or in a transaction not subject to, the
Securities Act and applicable state securities laws. See "Risk Factors--Risk
Factors Relating to the New Certificates and the Exchange Offer".

     NEITHER PSSA NOR THE TRUSTEE MAKES ANY RECOMMENDATION TO HOLDERS OF OLD
CERTIFICATES AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING ALL OR ANY
PORTION OF THEIR OLD CERTIFICATES PURSUANT TO THE EXCHANGE OFFER. IN ADDITION,
NO ONE HAS BEEN AUTHORIZED TO MAKE ANY SUCH RECOMMENDATION. HOLDERS OF OLD
CERTIFICATES MUST MAKE THEIR OWN DECISION WHETHER TO TENDER PURSUANT TO THE
EXCHANGE OFFER AND, IF SO, THE AGGREGATE AMOUNT OF OLD CERTIFICATES TO TENDER
AFTER READING THIS PROSPECTUS AND THE LETTER OF TRANSMITTAL AND CONSULTING WITH
THEIR ADVISERS, IF ANY, BASED ON THEIR OWN FINANCIAL POSITION AND REQUIREMENTS.

Expiration Date; Extensions; Amendments; Termination

     The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
February , 1999 (30 calendar days following the commencement of the Exchange
Offer), unless PSSA, in its sole discretion, instructs the Exchange Agent to
extend the Exchange Offer, in which case the term "Expiration Date" shall mean
the latest date to which the Exchange Offer is extended.

     In order to extend the Expiration Date, PSSA will notify the Exchange Agent
of any extension by oral or written notice and will cause the Exchange Agent to
notify the holders of the Old Certificates by means of a press release or other
public announcement prior to 9:00 A.M., New York City time, on the next business
day after the previously scheduled Expiration Date. Such announcement may state
that the Trust is extending the Exchange Offer for a specified period of time.

     PSSA reserves the right to cause the Trust and the Exchange Agent (i) to
delay acceptance of any Old Certificates, to extend the Exchange Offer or to
terminate the Exchange Offer and not permit acceptance of Old Certificates not
previously accepted if any of the conditions set forth herein under "--
Conditions" shall have occurred and shall not have been waived by PSSA, by
giving oral or written notice of such delay, extension or termination to the
Exchange Agent, or (ii) to cause the Trustee to amend the terms of the Exchange
Offer in any manner deemed by it to be advantageous to the holders of the Old
Certificates. Any such delay in acceptance, extension, termination or amendment
will be followed as promptly as practicable by oral or written notice thereof to
the Exchange Agent. If the Exchange Offer is amended in a manner determined by
PSSA to constitute a material change, PSSA will promptly cause such amendment to
be disclosed in a manner reasonably calculated to inform the holders of the Old
Certificates of such amendment.

     Without limiting the manner in which the Exchange Agent may choose to make
public announcement of any delay, extension, amendment or termination of the
Exchange Offer, the Exchange Agent shall have no obligation to publish,
advertise, or otherwise communicate any such public announcement, other than by
making a timely release to an appropriate news agency.

Procedures for Tendering

     To tender in the Exchange Offer, a holder must complete, sign and date the
Letter of Transmittal, or a facsimile thereof, have the signatures thereon
guaranteed if required by the Letter of Transmittal, and mail or otherwise
deliver such Letter of Transmittal or such facsimile, together with any other
required documents, to the Exchange Agent prior to 5:00 p.m., New York City
time, on the Expiration Date. In addition, either (i) certificates for such Old
Certificates must be received by the Exchange Agent along with the Letter of
Transmittal or (ii) the holder must comply with the guaranteed delivery
procedures described below. THE METHOD OF DELIVERY OF OLD CERTIFICATES, LETTERS
OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF
THE HOLDERS. IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED
MAIL, PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY. NO LETTERS OF
TRANSMITTAL OR OLD CERTIFICATES SHOULD BE SENT TO PSSA. Delivery of all
documents must be made to the Exchange Agent at its address set forth below.
Holders may also request their respective brokers, dealers, commercial banks,
trust companies or nominees to effect such tender for such holders.

     The tender by a holder of Old Certificates will constitute an agreement
between such holder and the Trust in accordance with the terms and subject to
the conditions set forth herein and in the Letter of Transmittal.

     Only a holder of Old Certificates may tender such Old Certificates in the
Exchange Offer. The term "holder" with respect to the Exchange Offer means any
person in whose name Old Certificates are registered on the books of the Trustee
or any other person who has obtained a properly completed bond power from the
registered holder.

     Any beneficial owner whose Old Certificates are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact such registered holder promptly and instruct such
registered holder to tender on his behalf. If such beneficial owner wishes to
tender on his own behalf, such beneficial owner must, prior to completing and
executing the Letter of Transmittal and delivering his Old Certificates, either
make appropriate arrangements to register ownership of the Old Certificates in
such owner's name or obtain a properly completed bond power from the registered
holder. The transfer of registered ownership may take considerable time.

     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by any member firm of a registered national
securities exchange or of the National Association of Securities Dealers, Inc.,
a commercial bank or trust company having an office or correspondent in the
United States or an "eligible guarantor" institution within the meaning of Rule
17Ad-15 under the Exchange Act (each an "Eligible Institution") unless the Old
Certificates tendered pursuant thereto are tendered (i) by a registered holder
who has not completed the box entitled "Special Issuance Instructions" or
"Special Delivery Instructions" on the Letter of Transmittal or (ii) for the
account of an Eligible Institution.

     If the Letter of Transmittal is signed by a person other than the
registered holder of any Old Certificates listed therein, such Old Certificates
must be endorsed or accompanied by bond powers and a proxy which authorizes such
person to tender the Old Certificates on behalf of the registered holder, in
each case as the name of the registered holder or holders appears on the Old
Certificates.

     If the Letter of Transmittal or any Old Certificates or bond powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and unless waived by the
Trustee, evidence satisfactory to the Trustee of their authority to so act must
be submitted with the Letter of Transmittal.

     All questions as to the validity, form, eligibility (including time of
receipt) and withdrawal of the tendered Old Certificates will be determined by
the Trustee in its sole discretion, which determination will be final and
binding. The Trustee reserves the absolute right to reject any and all Old
Certificates not properly tendered or any Old Certificates which, if accepted,
would, in the opinion of counsel for PSSA, be unlawful. The Trustee also
reserves the absolute right to waive any irregularities or conditions of tender
as to particular Old Certificates. The Trustee's interpretation of the terms and
conditions of the Exchange Offer (including the instructions in the Letter of
Transmittal) will be final and binding on all parties. Unless waived, any
defects or irregularities in connection with tenders of Old Certificates must be
cured within such time as the Trustee shall determine. Neither the Trustee nor
PSSA, nor the Exchange Agent nor any other person shall be under any duty to
give notification of defects or irregularities with respect to tenders of Old
Certificates, nor shall any of them incur any liability for failure to give such
notification. Tenders of Old Certificates will not be deemed to have been made
until such irregularities have been cured or waived. Any Old Certificates
received by the Exchange Agent that are not properly tendered and as to which
the defects or irregularities have not been cured or waived will be returned
without cost to such holder by the Exchange Agent to the tendering holders of
Old Certificates, unless otherwise provided in the Letter of Transmittal, as
soon as practicable following the Expiration Date.

     In addition, PSSA reserves the right in its sole discretion (i) to purchase
or make offers for any Old Certificates that remain outstanding subsequent to
the Expiration Date or, as set forth under "-- Conditions", to terminate the
Exchange Offer in accordance with the terms of the Registration Rights Agreement
and (ii) to the extent permitted by applicable law, to purchase Old Certificates
in the open market, in privately negotiated transactions or otherwise. The terms
of any such purchases or offers could differ from the terms of the Exchange
Offer.

Acceptance of Old Certificates for Exchange; Delivery of New Certificates

     Upon satisfaction or waiver of all of the conditions to the Exchange Offer,
all Old Certificates properly tendered will be accepted, promptly after the
Expiration Date, and the New Certificates will be issued promptly after
acceptance of the Old Certificates. For purposes of the Exchange Offer, Old
Certificates shall be deemed to have been accepted as validly tendered for
exchange when, as and if the Trustee has given oral or written notice thereof to
the Exchange Agent.

     In all cases, issuance of New Certificates for Old Certificates that are
accepted for exchange pursuant to the Exchange Offer will be made only after
timely receipt by the Exchange Agent of certificates for such Old Certificates,
a properly completed and duly executed Letter of Transmittal and all other
required documents. If any tendered Old Certificates are not accepted for any
reason set forth in the terms and conditions of the Exchange Offer or if Old
Certificates are submitted for a greater principal amount than the holder
desires to exchange, such unaccepted or nonexchanged Old Certificates will be
returned without expense to the tendering holder thereof as promptly as
practicable after the expiration or termination of the Exchange Offer.

Guaranteed Delivery Procedures

     If a registered holder of the Old Certificates desires to tender such Old
Certificates, and the Old Certificates are not immediately available, or time
will not permit such holder's Old Certificates or other required documents to
reach the Exchange Agent before the Expiration Date, a tender may be effected if
(i) the tender is made through an Eligible Institution, (ii) prior to the
Expiration Date, the Exchange Agent receives from such Eligible Institution a
properly completed and duly executed Letter of Transmittal (or a facsimile
thereof) and Notice of Guaranteed Delivery, substantially in the form provided
by PSSA (by facsimile transmission, mail or hand delivery), setting forth the
name and address of the holder of Old Certificates and the amount of Old
Certificates tendered, stating that the tender is being made thereby and
guaranteeing that within three New York Stock Exchange (the "NYSE") trading days
after the date of execution of the Notice of Guaranteed Delivery, the
certificates for all physically tendered Old Certificates, in proper form for
transfer, and any other documents required by the Letter of Transmittal will be
deposited by the Eligible Institution with the Exchange Agent and (iii) the
certificates for all physically tendered Old Certificates, in proper form for
transfer, and all other documents required by the Letter of Transmittal are
received by the Exchange Agent within three NYSE trading days after the date of
execution of the Notice of Guaranteed Delivery.

Withdrawal of Tenders

     Tenders of Old Certificates may be withdrawn at any time prior to 5:00
p.m., New York City time on the Expiration Date.

     For a withdrawal to be effective, a written notice of withdrawal must be
received by the Exchange Agent prior to 5:00 p.m., New York City time on the
Expiration Date at one of the addresses set forth below under "--Exchange
Agent". Any such notice of withdrawal must specify the name of the person having
tendered the Old Certificates to be withdrawn, identify the Old Certificates to
be withdrawn (including the principal amount of such Old Certificates) and
(where certificates for Old Certificates have been transmitted) specify the name
in which such Old Certificates are registered, if different from that of the
withdrawing holder. If certificates for Old Certificates have been delivered or
otherwise identified to the Exchange Agent, then, prior to the release of such
certificates, the withdrawing holder must also submit the serial numbers of the
particular certificates to be withdrawn and a signed notice of withdrawal with
signatures guaranteed by an Eligible Institution unless such holder is an
Eligible Institution. All questions as to the validity, form and eligibility
(including time of receipt) of such notices will be determined by the Trustee,
whose determination shall be final and binding on all parties. Any Old
Certificates so withdrawn will be deemed not to have been validly tendered for
exchange for purposes of the Exchange Offer. Any Old Certificates which have
been tendered for exchange but which are not exchanged for any reason will be
returned to the holder thereof without cost to such holder as soon as
practicable after withdrawal, rejection of tender or termination of the Exchange
Offer. Properly withdrawn Old Certificates may be retendered by following one of
the procedures described under "-- Procedures for Tendering" above at any time
on or prior to the Expiration Date.

Conditions

     Notwithstanding any other term of the Exchange Offer, Old Certificates will
not be required to be accepted for exchange, nor will New Certificates be issued
in exchange for any Old Certificates, and PSSA may cause the Trustee to
terminate or amend the Exchange Offer as provided herein before the acceptance
of such Old Certificates, if because of any change in law, or applicable
interpretations thereof by the Commission, PSSA determines that the Trust is not
permitted to effect the Exchange Offer. PSSA has no obligation to, and will not
knowingly, permit acceptance of tenders of Old Certificates by the Trust from
affiliates of PSSA (within the meaning of Rule 405 under the Securities Act) or
from any other holder or holders who are not eligible to participate in the
Exchange Offer under applicable law or interpretations thereof by the
Commission, or if the New Certificates to be received by such holder or holders
of Old Certificates in the Exchange Offer, upon receipt, will not be tradable by
such holder without restriction under the Securities Act and the Exchange Act
and without material restrictions under the "blue sky" or securities laws of
substantially all of the states of the United States.

Fees and Expenses

     The expenses of soliciting tenders pursuant to the Exchange Offer will be
borne by PSSA on behalf of the Trust pursuant to the Registration Rights
Agreement. The principal solicitation for tenders pursuant to the Exchange Offer
is being made by mail; however, additional solicitations may be made by
telegraph, telephone, telecopy or in person by officers and regular employees or
agents of PSSA on behalf of the Trust.

     PSSA will not make any payments to brokers, dealers or other persons
soliciting acceptances of the Exchange Offer. PSSA, however, will pay on behalf
of the Trust the Exchange Agent's reasonable and customary fees for its services
and will reimburse the Exchange Agent for its reasonable out-of-pocket expenses
in connection therewith. PSSA may also pay on behalf of the Trust, the
reasonable out-of-pocket expenses incurred by brokerage houses and other
custodians, nominees and fiduciaries in forwarding copies of the Prospectus and
related documents to the beneficial owners of the Old Certificates, and in
handling or forwarding tenders for exchange.

     The expenses to be incurred in connection with the Exchange Offer will be
paid by PSSA on behalf of the Trust, including fees and expenses of the Exchange
Agent and Trustee and accounting, legal, printing and related fees and expenses.

     PSSA will pay all transfer taxes, if any, applicable to the exchange of Old
Certificates pursuant to the Exchange Offer. If, however, certificates
representing New Certificates or Old Certificates for principal amounts not
tendered or accepted for exchange are to be delivered to, or are to be
registered or issued in the name of, any person other than the registered holder
of the Old Certificates tendered, or if tendered Old Certificates are registered
in the name of any person other than the person signing the Letter of
Transmittal, or if a transfer tax is imposed for any reason other than the
exchange of Old Certificates pursuant to the Exchange Offer, then the amount of
any such transfer taxes (whether imposed on the registered holder or any other
persons) will be payable by the tendering holder. If satisfactory evidence of
payment of such taxes or exemption therefrom is not submitted with the Letter of
Transmittal, the amount of such transfer taxes will be billed directly to such
tendering holder.

                       DESCRIPTION OF THE NEW CERTIFICATES

General

     The New Certificates will be denominated and distributions with respect
thereto will be payable in United States Dollars. The Trust Certificates
represent in the aggregate the entire beneficial ownership interest in the
Trust. The property of the Trust will consist of (i) the NSC Notes, (ii) all
payments on or collections in respect of the NSC Notes received on or after
April 13, 1998 together with any proceeds thereof, and (iii) all funds from time
to time deposited with the Trustee in accounts related to the Trust. The
property of the Trust will be held for the benefit of the holders of the Trust
Certificates by the Trustee. Holders of the New Certificates will receive
payments or distributions on each Distribution Date as described herein. See
"--Collections and Distributions."

     The Trust Certificates represent two classes of undivided fractional
beneficial interests in the assets of the Trust, and all distributions to
holders of the Trust Certificates will be made only from the property of the
Trust as described herein. The Trust Certificates are comprised of two classes
representing the entire undivided beneficial ownership of the Trust: the
Amortizing Class and the Residual Class (the Old Certificates currently
constitute, and the New Certificates along with any Old Certificates not
tendered in the Exchange Offer, will constitute the entire Amortizing Class).
The Amortizing Class has a current aggregate Certificate Principal Balance of
$68,089,189.08. The Residual Class has an aggregate Certificate Principal
Balance of $80,000,000. Subject to the occurrence of an Optional Redemption, a
Shortened Maturity Redemption, or an In-Kind Distribution, the Residual Class
Certificates evidence fractional undivided beneficial interests in all principal
payments on the NSC Notes and in interest accrued and paid on the NSC Notes
after May 15, 2017 at a rate of 7.90% per annum.

     Subject to the occurrence of an Optional Redemption, a Shortened Maturity
Redemption, or an In-Kind Distribution, distributions on the Amortizing Class
Certificates will be made semiannually on each Scheduled Distribution Date up to
and including May 15, 2017 in an amount equal to the amount of interest due and
received on the NSC Notes on such Distribution Date. The Trust Certificates do
not represent an interest in or obligation of PSSA, NSC, the NSC Notes Trustee
or the Trustee or any affiliate of any of the foregoing. The amount of interest
due on the NSC Notes on each Scheduled Distribution Date is the product of (i)
7.90%, (ii) 180 divided by 360, and (iii) $80,000,000 (less the principal amount
of any NSC Notes redeemed in part upon an Optional Redemption or exchanged for
Certificates as described herein).

     The aggregate "Certificate Principal Balance" of the Amortizing Class
Certificates was initially $69,048,275.30 and is currently $68,089,189.08. On
any Scheduled Distribution Date, the aggregate Certificate Principal Balance
will be reduced by the positive difference between (i) the semiannual Fixed
Payment made on such Scheduled Distribution Date and (ii) interest accrued on
the aggregate Certificate Principal Balance at the Yield to Amortizing Class
Final Distribution Date from the prior Scheduled Distribution Date (or, in the
case of the initial Scheduled Distribution Date of May 15, 1998, such interest
accrued from November 15, 1997). The Certificate Principal Balance of any
Amortizing Class Certificate will represent a pro rata portion of the
then-current aggregate Certificate Principal Balance of all outstanding
Amortizing Class Certificates. In the case of an Optional Redemption of less
than all of the NSC Notes, upon the distribution of the proceeds from such
Optional Redemption, the Certificate Principal Balance of each Amortizing Class
Certificate shall be reduced by the same percentage as the percentage of NSC
Notes redeemed.

     New Certificates may be transferred or exchanged for like Certificates of
the same Class at the corporate trust office or agency of the Trustee in the
City and State of New York, subject to the limitations provided in the Trust
Agreement, without the payment of any service charge, other than any tax or
governmental charge payable in connection therewith.

Form of the New Certificates

     The New Certificates will be issued in definitive registered form in
minimum denominations of $250,000 Certificate Principal Balance and integral
multiples of $1.00 in excess thereof.

Collections and Distributions on New Certificates

     Subject to the occurrence of an Optional Redemption or a Shortened Maturity
Redemption of the NSC Notes, scheduled distributions on the Amortizing Class
Certificates will consist of equal semiannual installments allocable to
principal and interest through May 15, 2017 (each, a "Fixed Payment"). Each
Fixed Payment will be allocated between interest accrued at a per annum rate
equal to 6.375% compounded semiannually (the "Yield to Amortizing Class Final
Distribution Date") on the then-outstanding Certificate Principal Balance of the
Amortizing Class Certificates, and the repayment of principal, as set forth in
Appendix B attached hereto. Although payments on the Amortizing Class
Certificates are denominated as principal and interest, the Amortizing Class
Certificates generally represent indirect beneficial ownership of solely the
interest payments on the NSC Notes on or before May 15, 2017 and will be paid
solely from interest payments on the NSC Notes; absent an Optional Redemption, a
Shortened Maturity Redemption, or an In-Kind Distribution, on or prior to May
15, 2017, the Amortizing Class Certificateholders have no right to any portion
of the principal payments on the NSC Notes. The Amortizing Class Certificates
are scheduled to be paid in full on May 15, 2017 (the "Amortizing Class Final
Distribution Date"). The actual final payment date could occur later in the
event of a payment default on the NSC Notes, and could occur earlier in the case
of an Optional Redemption, a Shortened Maturity Redemption, or an In-Kind
Distribution.

     Distributions with respect to New Certificates will be made at the
corporate trust office or agency of the Trustee in The City of New York

     Any cash distribution on the New Certificates, upon a liquidation of the
Trust as described below, will be made (i) in U.S. Dollars by or on behalf of
the Trustee on the date of the distribution and (ii) by check drawn on, or wire
transfer, of immediately available funds, but, with respect to the latter, only
if appropriate wire transfer instructions have been received in writing by the
Trustee not later than fifteen calendar days prior to the date of the
distribution. If a holder of New Certificates wishes to receive cash payments by
wire transfer, such holder shall provide appropriate wire transfer instructions
by delivery of a written notice to the Trustee not later than fifteen calendar
days prior to the date of the distribution, which will remain in effect until
revoked by written notice to such Trustee received not later than fifteen
calendar days prior to the date of the distribution. Any cash distribution by
the Trustee to the New Certificates shall be made, subject to timely receipt of
payments on the NSC Notes and solely to the extent of Available Funds. See
"--Shortened Maturity Redemption" and "--Optional Redemption." "Available Funds"
means, as of any date of the distribution, the aggregate amount received on or
with respect to the NSC Notes during the period from the preceding date of the
distribution up to and including such date of the distribution (each such
period, a "Collection Period"), and deposited in the Collection Account and
available for distribution on such date of the distribution.

     If a payment with respect to the NSC Notes is made to the Trustee after the
date on which such payment was due, the Trustee will distribute any such amounts
received on the Business Day thereafter as if such funds had constituted
Available Funds on the date of the distribution immediately preceding such
Business Day; provided, however, that the Record Date for such distribution
shall be fifteen days prior to such Business Day and no additional amounts will
accrue on the Trust Certificates or be owed to holders of Trust Certificates in
respect of such distribution.

     All amounts received on or with respect to the NSC Notes shall be held
uninvested by the Trustee. On May 15, 2017, the Trustee will distribute the NSC
Notes in kind to the holders of Residual Class Certificates, unless an Optional
Redemption, a Shortened Maturity Redemption, or an In-Kind Distribution has
occurred on or prior to such date.

     In the event that PSSA is required to repurchase the NSC Notes as a result
of a breach of its representation and warranty as to its title to the NSC Notes
immediately prior to the transfer thereof to the Trustee, the Trustee will
distribute the repurchase price received from PSSA to the holders of the
Residual Class Certificates and the Amortizing Class Certificates, respectively,
in the same ratio as (i) the present value of all originally scheduled future
payments on the NSC Notes after May 15, 2017 bears to (ii) the present value of
all originally scheduled future payments on the Amortizing Class Certificates,
discounted semiannually in each case at a rate of 7.90 percent per annum to the
date on which the repurchase price is distributed. Such ratio will be calculated
by PSSA, as calculation agent, and such distribution will be made fifteen days
after receipt of the repurchase price.

Optional Redemption

     The NSC Notes will be redeemable prior to maturity, as a whole or in part,
at the option of NSC (an "Optional Redemption"), upon not less than 30 nor more
than 60 days' prior written notice, at any time, at a redemption price equal to
the greater of (i) 100% of the principal amount being redeemed and (ii) the sum
of the present values of the remaining scheduled payments of principal and
interest thereon discounted to the date of redemption (an "Optional Redemption
Date") on a semiannual basis at the Treasury Yield (as defined herein) plus 20
basis points, together with accrued interest to the date of redemption. In the
event of an Optional Redemption, the Trustee will distribute the payment
received on the NSC Notes on the Optional Redemption Date to the holders of the
Amortizing Class Certificates and the Residual Class Certificates, respectively,
in the same ratio as (i) the present value of all originally scheduled future
payments on the Amortizing Class Certificates bears to (ii) the present value of
all originally scheduled future payments on the NSC Notes after May 15, 2017,
discounted semiannually in each case at a rate of 7.90% per annum (such ratio
being the "Distribution Ratio") to the Optional Redemption Date. Such ratio will
be calculated by the Company, as calculation agent (the "Calculation Agent"). In
the case of such an Optional Redemption of less than all of the NSC Notes, the
Trustee will distribute the payment received on the NSC Notes on the Optional
Redemption Date to the holders of the Amortizing Class Certificates and the
Residual Class Certificates on the basis of the Distribution Ratio as of the
Optional Redemption Date on a pro rata basis; such a distribution will result in
a reduction (based on the percentage of NSC Notes redeemed) of the Residual
Class Certificates Certificate Principal Balance and a recalculation of the
Certificate Principal Balance of, and Fixed Payments with respect to, the
Amortizing Class Certificates based on the remaining NSC Notes after such
redemption. A table showing the percentages of such distribution that would be
distributable to the Amortizing Class Certificates and the Residual Class
Certificates, respectively, assuming that such a distribution date occurs on a
Scheduled Distribution Date, is attached hereto as Appendix A.

Shortened Maturity Redemption

     Upon the occurrence of a Tax Event (as defined below) with respect to the
NSC Notes, NSC has the right to shorten the maturity of the NSC Notes (i) to the
minimum extent required, in the opinion of nationally recognized independent tax
counsel, such that, after the shortening of the maturity, interest paid on the
NSC Notes will be deductible for U.S. federal income tax purposes or, (ii) if
such counsel is unable to opine definitively as to such minimum period, the
minimum extent so required as determined in good faith by the Board of Directors
of NSC after receipt of an opinion of such counsel regarding the applicable
legal standards. (Any such new maturity date is referred to herein as the
"Shortened Maturity Date.") If the Shortened Maturity Date is on or prior to May
15, 2017, the Amortizing Class Certificates and the Residual Class Certificates
will be redeemed on the Shortened Maturity Date (a "Shortened Maturity
Redemption"). The Trustee will distribute the payment received on the NSC Notes
on the Shortened Maturity Date to the holders of each class of Certificates on
the basis of the Distribution Ratio as of the Shortened Maturity Date. Such
ratio will be calculated by the Calculation Agent. A Shortened Maturity
Redemption as a result of a Tax Event may increase the amount of original issue
discount required to be included in a holder's ordinary gross income. See "U.S.
Federal Income Tax Consequences--Purchase and Holding of Trust Certificates." A
table showing the percentages of such distribution that would be distributable
to the Amortizing Class Certificates and the Residual Class Certificates,
respectively, assuming that such a distribution date occurs on a Scheduled
Distribution Date, is attached hereto as Appendix A.

     A "Tax Event" means that NSC shall have received an opinion of nationally
recognized independent tax counsel to the effect that, as a result of (a) any
amendment to, clarification of, or change (including any announced prospective
amendment, clarification or change) in any law, or any regulation thereunder, of
the United States, (b) any judicial decision, official administrative
pronouncement, ruling, regulatory procedure or regulation, including any notice
or announcement of intent to adopt or promulgate any ruling, regulatory
procedure or regulation (any of the foregoing, an "Administrative or Judicial
Action"), or (c) any amendment to, clarification of, or change in any official
position with respect to, or any interpretation of, an Administrative or
Judicial Action or a law or regulation of the United States that differs from
the theretofore generally accepted position or interpretation, in each case,
occurring on or after May 19, 1997, there is more than an insubstantial increase
in the risk that interest paid by NSC on the NSC Notes is not, or will not be,
deductible, in whole or in part, by NSC for United States federal income tax
purposes.

Distribution of the NSC Notes on Payment Default or Acceleration

     If a Payment Default or an Acceleration with respect to the NSC Notes
occurs on or prior to May 15, 2017, the Trustee will make an in-kind
distribution (an "In-Kind Distribution") of the remaining NSC Notes to the
holders of the Residual Class Certificates and the Amortizing Class
Certificates. A "Payment Default" means a default in the payment of any amount
due on the NSC Notes from NSC after the same becomes due and payable (and the
expiration of any applicable grace period on the NSC Notes). An "Acceleration"
means the acceleration of the maturity of the NSC Notes following the occurrence
of any default on the NSC Notes other than a Payment Default, notwithstanding
any subsequent rescission and annulment of such Acceleration by the requisite
holders of the entire series of NSC Notes. The In-Kind Distribution will be made
to the holders of Amortizing Class Certificates and Residual Class Certificates
on the basis of the Distribution Ratio as of such Payment Default or
Acceleration. Such ratio will be calculated by the Calculation Agent. To the
extent necessary to avoid a distribution of NSC Notes in unauthorized
denominations, the Trustee will cause the liquidation in a commercially
reasonable manner of such NSC Notes as are necessary, and will distribute the
proceeds therefrom to the holders of Amortizing Class Certificates and Residual
Class Certificates based on their respective rights to NSC Notes in unauthorized
denominations. An In-Kind Distribution may be treated in whole or in part as
equivalent to a taxable sale or exchange. See "U.S. Federal Income Tax
Consequences--Distributions." A table showing the percentages of such
distribution that would be distributable to the Amortizing Class Certificates
and the Residual Class Certificates, respectively, assuming that such
distribution occurs on a Scheduled Distribution Date, is attached hereto as
Appendix A.

Exchange of Certificates for NSC Notes

     Any holder of both Amortizing Class Certificates and Residual Class
Certificates may, by delivery of a notice to the Trustee substantially in the
form of the Notice of Exchange attached to a Certificate (a "Notice of
Exchange") not less than 30 and not more than 45 days prior to any Scheduled
Distribution Date other than May 15, 2017, elect to exchange Certificates of
both Classes for the NSC Notes on such Scheduled Distribution Date (the
"Exchange Date"). In order to exercise such right, the holder shall tender to
the Trustee on the Exchange Date immediately succeeding such notice both (a)
Amortizing Class Certificates evidencing the percentage specified in the Notice
of Exchange (which shall not be less than 10%) of the aggregate Certificate
Principal Balance of all Amortizing Class Certificates then outstanding and (b)
Residual Class Certificates evidencing the same percentage of the aggregate
Certificate Principal Balance of all Residual Class Certificates then
outstanding as is represented by the Amortizing Class Certificates tendered by
such holder.

     Upon tender of such Certificates, duly endorsed by the holder to the
Trustee, the Trustee shall transfer to the holder (or its designee specified in
the Notice of Exchange) a principal amount of NSC Notes comprising the same
percentage of the NSC Notes then held in the Trust as the percentage of
Amortizing Class Certificates and Residual Class Certificates tendered by such
holder on such Scheduled Distribution Date, rounded down to the nearest
authorized denomination of NSC Notes. Upon such exchange, the Trustee shall
cancel the tendered Certificates, provided that if the amount of the NSC Notes
delivered to the holder or its designee was rounded down in accordance with the
preceding sentence, the Trustee shall issue to such holder new Certificates of
each Class evidencing percentage interests of such Class (regardless of whether
such interests would otherwise be authorized denominations) equal to the amount
of such Class in excess of the amount accepted for such exchange.

     The delivery of a Notice of Exchange shall be irrevocable; provided,
however, that if (i) the proceeds of an Optional Redemption, a Shortened
Maturity Redemption or an In-Kind Distribution are to be distributed on the
Exchange Date to which such Notice of Exchange relates or (ii) if prior to such
Exchange Date, the Trustee gives notice to holders that the proceeds of an
Optional Redemption, a Shortened Maturity Redemption or an In-Kind Distribution
are scheduled to be distributed on a date subsequent to such Exchange Date, such
Notice of Exchange shall be automatically deemed canceled and be of no further
force and effect.

     Any holder tendering Certificates in exchange for the NSC Notes on an
Exchange Date shall be entitled to receive cash distributions otherwise payable
on such Certificates on such Exchange Date.

     No Further Rule 3a-7 Limitation

     As a result of the rating assigned to the New Certificates at initial
issuance, they will not be subject to restrictions on transfer applicable to the
Old Certificates pursuant to Rule 3a-7.

                       DESCRIPTION OF THE TRUST AGREEMENT

General


     The following summary of certain provisions of the Trust Agreement and the
Trust Certificates does not purport to be complete and such summary is qualified
in its entirety by reference to the detailed provisions of the Trust Agreement
incorporated by reference hereto as described under "Incorporation of Certain
Documents by Reference." Article and section references in parentheses below are
to articles and sections in the Trust Agreement. Wherever particular sections or
defined terms of the Trust Agreement are referred to, such sections or defined
terms are incorporated herein by reference as part of the statement made, and
the statement is qualified in its entirety by such reference.

The Trustee

     The Bank of New York, a New York banking corporation, acts as trustee of
the Trust pursuant to the Trust Agreement. The Trustee's offices are located at
101 Barclay Street, 12th Floor East, New York, New York 10286, Attention:
Corporate Trust.

     The Trust Agreement provides that the Trustee and any director, officer,
employee or agent thereof will be indemnified by PSSA and held harmless against
any loss, liability or expense incurred in connection with any legal action
relating to the Trust Agreement or the Trust Certificates or the performance of
the Trustee's duties under the Trust Agreement, other than any loss, liability
or expense (i) that constitutes a specific liability of the Trustee under the
Trust Agreement or (ii) incurred by reason of willful misfeasance, bad faith or
negligence in the performance of the Trustee's duties under the Trust Agreement
or as a result of a breach, or by reason of reckless disregard, of the Trustee's
obligations and duties under the Trust Agreement. Pursuant to the Trust
Agreement, as compensation for the performance of its duties thereunder, the
Trustee is entitled to payment of trustee fees and reimbursement of expenses by
PSSA pursuant to a separate agreement with PSSA, but shall not have any claim
against the Trust with respect thereto.

     The Trustee makes no representations as to the validity or sufficiency of
the Trust Agreement, the New Certificates or the NSC Notes or any related
document. The Trustee is required to perform only those duties specifically
required under the Trust Agreement. However, upon receipt of the various
certificates, reports or other instruments required to be furnished to it, the
Trustee is required to examine such documents and to determine whether they
conform to the applicable requirements of the Trust Agreement.

     The Trustee is unaffiliated with, but may have normal banking relationships
with, PSSA and its affiliates.

     The Trust Agreement and, upon consummation of the Exchange Offer, the
provisions of the Trust Indenture Act of 1939, as amended, incorporated by
reference therein, contain limitations on the rights of the Trustee thereunder,
should it become a creditor of the Trust, to obtain payment of claims in certain
cases or to realize on certain property received by it in respect of any such
claims, as security or otherwise. The Trustee is permitted to engage in other
transactions; provided, however, that if it acquires any conflicting interest
(as defined) it must eliminate such conflict or resign.

Event of Default

     There are no events of default with respect to the Trust Certificates.

Voting Rights

     Voting rights will be allocated between the holders of Residual Class
Certificates, on the one hand, and the holders of Amortizing Class Certificates
on the other, respectively, at any date of determination in the same ratio as
(i) the present value of all originally scheduled future payments on the NSC
Notes after May 15, 2017 bears to (ii) the present value of all originally
scheduled future payments on the Amortizing Class Certificates, discounted
semiannually in each case at a rate of 7.90 percent per annum to the date of
determination. Such ratio will be calculated by the Calculation Agent. All
voting rights with respect to the Residual Class Certificates will be allocated
among all holders of Residual Class Certificates in proportion to the respective
Certificate Principal Balances of the then-outstanding Residual Class
Certificates held by such holders on any date of determination. All voting
rights with respect to the Amortizing Class Certificates will be allocated among
all holders of Amortizing Class Certificates in proportion to the respective
Notional Amounts of the then-outstanding Amortizing Class Certificates held by
such holders on any date of determination.

     The required percentage of Voting Rights of those Classes of Trust
Certificates that are materially adversely affected by any modification or
amendment of the Trust Agreement necessary to consent to such modification or
amendment is 100%.

Voting with Respect to the NSC Notes

     The Trustee, as the holder of the NSC Notes, has the right to vote and give
consents and waivers in respect of the NSC Notes as permitted by the NSC Notes
Indenture with respect thereto and except as otherwise limited by the Trust
Agreement. In the event that the Trustee receives a request from NSC for its
consent to any amendment, modification or waiver of the NSC Notes or any
document relating thereto, or receives any other solicitation for any action
with respect to the NSC Notes, 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 holders
of Amortizing Class Certificates and Residual Class Certificates 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 Voting Rights of the
Certificates) as the Certificates of the Trust were actually voted or not voted
by the holders of Amortizing Class Certificates and Residual Class Certificates
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
to the contrary herein, the Trustee shall at no time vote in favor of or consent
to any matter (i) which would alter the timing or amount of any payment on the
NSC Notes, including, without limitation, any demand to accelerate the NSC
Notes, (ii) which would result in the exchange or substitution of any NSC Note
pursuant to a plan for the refunding or refinancing of such NSC Note, (iii)
which would alter the currency in which any payment is required to be made on
the NSC Notes, (iv) which would change the voting rights granted to holders of
the NSC Notes under the NSC Notes Indenture, or (v) which would impair in any
material respect any rights of the Trustee or holders of the NSC Notes to
enforce remedies against NSC under the NSC Notes Indenture, except in each case
with the unanimous consent of the holders of Amortizing Class Certificates and
Residual Class Certificates, and subject to the requirement that such vote or
consent would not, based on an Opinion of Counsel, cause the Trust to fail to be
characterized as a grantor trust for U.S. federal income tax purposes or result
in a sale or exchange of any Certificate for federal income tax purpose. The
Trustee shall have no liability for any failure to act resulting from the
holders of Amortizing Class Certificates and Residual Class Certificates' late
return of, or failure to return, directions requested by the Trustee from the
holders of Amortizing Class Certificates and Residual Class Certificates.

Modification and Waiver

     The Trust Agreement may be amended by PSSA and the Trustee, without notice
to or consent of the holders of Trust Certificates, for certain purposes
including (i) to cure any ambiguity, (ii) to correct or supplement any provision
therein which may be inconsistent with any other provision therein, (iii) to add
or supplement any Credit Support (as defined in the Trust Agreement) for the
benefit of any holders of Trust Certificates, (iv) to add to the covenants,
restrictions or obligations of PSSA or the Trustee for the benefit of the
holders of Trust Certificates, (v) to add, change or eliminate any other
provisions with respect to matters or questions arising under such Trust
Agreement, or (vi) to comply with any requirements imposed by the Internal
Revenue Code of 1986 (the "Code"); provided that (x) any such amendment
described in (i) through (vi) will not, as evidenced by an Opinion of Counsel,
cause the Trust to fail to qualify as a grantor trust for federal income tax
purposes or result in a sale or exchange of any Certificate for tax purposes and
(y) the Trustee has received (1) a certificate of PSSA to the effect that such
amendment will not have a material adverse effect on any class of holders of
Trust Certificates and (2) written confirmation from each Rating Agency rating
such Trust Certificates, if any, that such amendment will not cause such Rating
Agency to reduce or withdraw the then current rating thereof. Without limiting
the generality of the foregoing, the Trust Agreement may also be modified or
amended from time to time by PSSA and the Trustee, with the consent of the
holders of Certificates of each class evidencing not less than the "Required
Percentage--Amendment" of the Voting Rights of those Trust Certificates of such
Classes that are affected by such modification or amendment for the purpose of
adding any provision to or changing in any manner or eliminating any provision
of the Trust Agreement or of modifying in any manner the rights of such holders
of Trust Certificates; provided that any such amendment shall not, as evidenced
by an Opinion of Counsel, cause the Trust to fail to qualify as a grantor trust
for federal income tax purposes.

     No such modification or amendment may, however, (i) reduce in any manner
the amount of or alter the timing of, distributions or payments which are
required to be made on any Certificate without the consent of the holder of such
Trust Certificate or (ii) reduce the aforesaid Required Percentage of Voting
Rights required for the consent to any such amendment without the consent of the
holders of all Certificates covered by the Trust Agreement then outstanding.

Reports to Holders of Trust Certificates; Notices

     Reports to Holders of Trust Certificates. With each distribution to holders
of Trust Certificates, the Trustee will forward or cause to be forwarded to each
such holder of Trust Certificates and to PSSA a statement setting forth: (i) the
amount of such distribution to holders of Trust Certificates of such Class
allocable to principal, if any, on the Trust Certificates of such Class; (ii)
the amount of compensation received by the Trustee for the period relating to
such Distribution Date, (iii) the aggregate stated principal amount or, if
applicable, notional principal amount of the NSC Notes and the current interest
rate thereon at the close of business on such Distribution Date; and (iv) the
aggregate Certificate Principal Balance or aggregate Notional Amount, if
applicable, of each Class of Trust Certificates at the close of business on such
Distribution Date, separately identifying any reduction in such aggregate
Certificate Principal Balance or aggregate Notional Amount due to the allocation
of any Realized Losses or otherwise. In the case of information furnished
pursuant to subclauses (i) and (ii) above, the amounts shall be expressed as a
U.S. dollar amount per minimum denomination of Trust Certificates or for such
other specified portion thereof. Subject to the occurrence of a Shortened
Maturity Redemption or an In-Kind Distribution, the holders of New Certificates
will receive no such reports until the distribution in-kind on May 15, 2017.
Within a reasonable period of time after the end of each calendar year, the
Trustee shall furnish to each person who at any time during the calendar year
was a holder of Trust Certificates a statement containing the information set
forth in subclauses (i) and (ii) above, aggregated for such calendar year or the
applicable portion thereof during which such person was a holder of Trust
Certificates. Such obligation of the Trustee shall be deemed to have been
satisfied to the extent that substantially comparable information shall be
provided by the Trustee pursuant to any requirements of the Code as are from
time to time in effect.

     Notices. Any notice required to be given to a holder of a Registered
Certificate will be mailed to the address of such holder set forth in the
applicable Certificate Register.

Replacement Certificates

     If a New Certificate is mutilated, destroyed, lost or stolen, it may be
replaced at the corporate trust office or agency of the applicable Trustee in
the City and State of New York, upon payment by the holder of such expenses as
may be incurred by the applicable Trustee in connection therewith and the
furnishing of such evidence and indemnity as such Trustee may require. Mutilated
Certificates must be surrendered before new Certificates will be issued.

Termination of the Trust

     The Trust shall terminate upon the earliest of (i) the distribution of the
NSC Notes on May 15, 2017, (ii) the date of any Optional Redemption or Shortened
Maturity Redemption or (iii) the date of an In-Kind Distribution.

     The final distribution will be made only upon surrender and cancellation of
the Trust Certificates at an office or agency appointed by the Trustee.

Governing Law

     The Trust Agreement and the Trust Certificates will be governed by, and
construed in accordance with, the laws of the State of New York without
reference to such State's principles of conflicts of law. Upon consummation of
the Exchange Offer, the Trust Agreement will be subject to the provisions of the
Trust Indenture Act of 1939, as amended, that are required to be part of the
Trust Agreement and will, to the extent applicable, be governed by such
provisions.

                      U.S. FEDERAL INCOME TAX CONSEQUENCES

     The following is a summary of U.S. federal income tax consequences material
to the purchase, ownership and disposition of Trust Certificates and the
exchange of Old Certificates for New Certificates (the "Exchange") pursuant to
the Exchange Offer. The summary does not purport to be a comprehensive
description of all of the tax consequences that may be relevant to a decision to
purchase Trust Certificates by any particular investor, including tax
consequences that arise from rules of general application to all taxpayers or to
certain classes of taxpayers or that are generally assumed to be known by
investors. Thus, for example, except where otherwise noted, the discussion below
is addressed to holders that are "U.S. persons" and that hold Trust Certificates
as capital assets. It does not discuss state, local or foreign tax consequences,
nor does it discuss all the tax consequences that may be relevant to a holder
subject to special rules, including dealers in securities or commodities, banks,
savings and loan associations and similar financial institutions, tax-exempt
organizations, insurance companies, taxpayers that hold Trust Certificates as
part of a hedged or integrated transaction (such as a "straddle" or "conversion
transaction") for U.S. federal income tax purposes, or taxpayers whose
functional currency is other than the U.S. dollar. It also does not discuss tax
consequences for individuals or entities taxed as individuals. The discussion
below is based on the Code and the regulations issued thereunder, and
interpretations of law, rulings and decisions currently in effect, all of which
are subject to change. Any such change may be applied retroactively, and may
adversely affect the U.S. federal income tax consequences described herein.

     The term "U.S. person" means a citizen or resident of the United States, a
corporation, partnership or other entity created or organized in or under the
laws of the United States or any political subdivision thereof, an estate the
income of which is subject to U.S. federal income taxation regardless of its
source, or a trust if (i) a U.S. court is able to exercise primary supervision
over the trust's administration and (ii) one or more U.S. persons have the
authority to control all of the trust's substantial decisions.

     PROSPECTIVE HOLDERS SHOULD CONSULT THEIR TAX ADVISORS AS TO THE U.S.
FEDERAL TAX CONSEQUENCES TO THEM OF THE EXCHANGE, AND OF ACQUIRING, HOLDING AND
DISPOSING OF TRUST CERTIFICATES, INCLUDING, IN PARTICULAR, THE APPLICATION IN
THEIR PARTICULAR CIRCUMSTANCES OF THE TAX CONSEQUENCES DISCUSSED BELOW, AS WELL
AS THE APPLICATION OF STATE, LOCAL, FOREIGN OR OTHER TAX LAWS.


Exchange of Old Certificates for New Certificates

     In the opinion of Cleary, Gottlieb, Steen & Hamilton, the Exchange will not
be a taxable event for U.S. federal income tax purposes. As a result, a holder
of an Old Certificate whose Old Certificate is accepted in the Exchange Offer
will not recognize gain on the Exchange. The New Certificates will have the same
"issue price" (and "adjusted issue price" immediately after the Exchange) as the
Old Certificates, and each tendering holder will have the same adjusted basis
and holding period in the New Certificates as it had in the Old Certificates
immediately before the Exchange.

Characterization of the Trust

     For U.S. federal income tax purposes, the Trust will not be treated as an
association taxable as a corporation (or a publicly traded partnership treated
as an association) in the opinion of Cleary, Gottlieb, Steen & Hamilton.
Although the characterization of the Trust is not certain, the Trust should be
treated for U.S. federal income tax purposes as a grantor trust, and the Trustee
intends to report income, gain, loss and deductions to the Internal Revenue
Service ("IRS") on that basis. If the Trust were not classified as a grantor
trust, it would be classified as a partnership.
As a consequence, the Trust will not be subject to U.S. federal income taxation.

     Prospective investors should be aware that no rulings have been or are
expected to be sought from the IRS with respect to the classification of the
Trust (or any of the other U.S. federal income tax consequences discussed in
this summary) and there can be no assurance that the IRS will agree with the
characterization of the Trust as a grantor trust (or with the other U.S. federal
income tax consequences discussed herein). See "--Alternative
Characterizations." Accordingly, prospective purchasers are urged to consult
their tax advisers regarding the U.S. federal income tax classification of the
Trust.

     Under the U.S. federal income tax rules applicable to grantor trusts, a
holder of a Trust Certificate will be treated as owning the rights to those
payments on the NSC Notes that are allocable to that Trust Certificate. The sale
of a Trust Certificate will be considered a sale of a holder's interest in those
payments. In addition, a holder may deduct its pro rata share of the fees and
other deductible expenses paid by the Trust, at the same time and to the same
extent as such items would be deducted by the holder if the holder paid directly
a pro rata portion of the amounts paid by the Trust.

     The NSC Notes Prospectus indicates that the NSC Notes underlying the Trust
Certificates were sold based on NSC's belief that they constitute indebtedness
of NSC for U.S. federal income tax purposes. The following discussion is based
on the assumption that the NSC Notes will constitute debt instruments in their
entirety. Except for the discussion under "--Alternative Characterizations," the
following also assumes that the Trust will be classified as a grantor trust.

Purchase and Holding of Trust Certificates

     A purchaser of a Trust Certificate will be treated as having acquired the
rights to those payments on the NSC Notes that are allocable to that Trust
Certificate and will be taxed under the "stripped bond" rules of the Code. The
holder will be treated as having purchased a newly issued, single debt
instrument providing for payments equal to the payments on the NSC Notes
allocable to the Trust Certificate, and having original issue discount ("OID")
equal to the excess of the sum of such payments over the holder's purchase price
for the Trust Certificate (which would be treated as the "issue price"). In
determining the purchase price for a Trust Certificate for this purpose, a
portion of the purchase price of the Trust Certificate may be separately
allocated to amounts held by the Trust pending distribution to holders (the
recovery of which amounts would not be taxable). Any such allocation would
reduce the amount paid for (and the amount payable on) such Trust Certificate.

     Under the OID rules, in general, each holder of a Trust Certificate,
whether such holder uses the cash or the accrual method of tax accounting, will
be required to include in ordinary gross income the sum of the "daily portions"
of OID on the Trust Certificate for all days during the taxable year that the
holder owns the Trust Certificate. The daily portions of OID on a Trust
Certificate are determined by allocating to each day in any accrual period a
ratable portion of the OID allocable to that accrual period. Accrual periods may
be any length and may vary in length over the term of a Trust Certificate,
provided that no accrual period is longer than one year and each scheduled
payment of principal or interest occurs on either the final day or the first day
of an accrual period. The amount of OID on a Trust Certificate allocable to each
accrual period is determined by multiplying the "adjusted issue price" of the
Trust Certificate at the beginning of the accrual period by the yield to
maturity of such Trust Certificate (appropriately adjusted to reflect the length
of the accrual period). The yield to maturity of a Trust Certificate is the
discount rate that causes the present value of all payments on the Trust
Certificate as of its issue date to equal the issue price of such Trust
Certificate. The "adjusted issue price" of a Trust Certificate at the beginning
of any accrual period will generally be the sum of its issue price and the
amount of OID allocable to all prior accrual periods, reduced by the amount of
all payments made with respect to such Trust Certificate in all prior accrual
periods.

     Because holders of Residual Class Certificates will not be receiving
current distributions, OID will be includible as income prior to the receipt of
cash attributable to such income and the amount of OID includible in income will
increase each year.

     It is not clear how the possibility of a Shortened Maturity Redemption or
an Optional Redemption, and the resulting distribution to Amortizing Class
Certificate holders of a portion of the payment received by the Trust on the
Shortened Maturity Date or Optional Redemption Date, as the case may be, should
be taken into account for purposes of determining the taxation of holders at,
and prior to, the Shortened Maturity Date or Optional Redemption Date
(including, but not limited to, the amount of OID required to be included by
holders in ordinary gross income). The Trustee intends to take the position that
the possibility of a Shortened Maturity Redemption or Optional Redemption should
not affect the U.S. federal income tax consequences to holders prior to the
Shortened Maturity Date or Optional Redemption Date. Under this treatment, if
the maturity of the NSC Notes was shortened as a result of a Shortened Maturity
Redemption, a holder would be treated, solely for OID purposes, as acquiring a
newly issued OID bond, and would be required to determine OID on the newly
issued bond taking into account the Shortened Maturity Date and the amount
required to be distributed to the holder on that date. The amount of OID
required to be included in the holder's ordinary gross income as a result of the
redetermination could be more or less than the amount determined without taking
into account the Shortened Maturity Redemption. In addition, under this
treatment, if the maturity of the NSC Notes was shortened as a result of an
Optional Redemption, a holder would be treated as disposing of the NSC Notes in
whole, in the case of an Optional Redemption of all of the NSC Notes, or in
part, in the case of an Optional Redemption of less than all of the NSC Notes,
on the Optional Redemption Date with the consequences described below under
"--Sale or Exchange of Certificates or NSC Notes." There can be no assurance,
however, that the IRS will not take a different position on the effect of a
potential Shortened Maturity Redemption or Optional Redemption, which position
may have less favorable tax consequences. See "-Alternative Characterizations."
Prospective purchasers should consult their tax advisers with respect to the
effect of a potential Shortened Maturity Redemption or Optional Redemption.

     The Trust currently intends, for information reporting purposes, to account
for OID reportable by holders of Trust Certificates by reference to the first
price at which a substantial amount of the Trust Certificates is sold to
purchasers (other than Prudential Securities), even though the amount of OID
will differ for subsequent purchasers. Such prospective purchasers should
consult their tax advisers regarding the proper calculation of OID.

Distributions

     Cash distributions on the Trust Certificates will not be subject to
additional taxation. An In-Kind Distribution may be treated in whole or in part
as equivalent to a sale or exchange.

Optional Exchange of Certificates for the NSC Notes

     The distribution of a principal amount of the NSC Notes comprising a
specified percentage of the NSC Notes then held in the Trust in exchange for the
same percentage of Amortizing Class Certificates and Residual Class
Certificates, and the issuance of new Certificates, if any, evidencing smaller
equal percentage interests of each such Class will not be subject to additional
taxation. The treatment of a holder that exchanges such Certificates for the NSC
Notes is unclear. The provisions of the Code and Treasury regulations relating
to stripped bonds do not specifically provide authority or a mechanism for
ceasing to apply the stripped bond rules under such circumstances. It therefore
appears likely that such a holder would be required to continue to report
income, gain or loss on the NSC Notes so acquired in the same manner as if it
still held the Certificates surrendered in exchange for the NSC Notes.

Sale or Exchange of Certificates or NSC Notes

     A Certificateholder's tax basis in a Certificate generally will equal the
cost of the Certificate increased by any amounts includible in income as OID,
and reduced by any payments made on the Certificate.

     Upon the sale or exchange of a Certificate, a holder generally will
recognize gain or loss equal to the difference between the amount realized on
the sale or exchange and the holder's tax basis in the Certificate. Gain or loss
recognized by a holder on the sale or exchange of a Certificate generally will
be capital gain or loss, and will be long-term capital gain or loss if the
holder is considered to have held the Certificate for more than one year at the
time of the disposition. Long-term capital gain recognized by an individual
holder generally will be subject to a maximum tax rate of 20 percent in respect
of Trust Certificates held for more than one year.

     A holder will recognize gain or loss on any sale by the Trust of the NSC
Notes, including in connection with an In-Kind Distribution or pursuant to an
Optional Redemption of all or part of the NSC Notes, equal to the difference
between the portion of the amount realized on the sale allocable to the holder
and the allocable portion of the holder's basis in the Certificate. In the event
of an Optional Redemption of less than all of the NSC Notes, a holder will
calculate gain or loss by assuming that the NSC Notes consist of two debt
instruments, one of which is retired and one of which remains outstanding. The
adjusted issue price, holder's adjusted basis and accrued but unpaid OID of the
NSC Notes, determined immediately before the partial Optional Redemption, will
be allocated between those two instruments based on the portion of the NSC Notes
that is treated as retired by the partial Optional Redemption.

Alternative Characterizations

     As noted above, there can be no assurance that the IRS will agree with the
characterization of the Trust as a grantor trust. It is possible that the IRS
could seek to classify the Trust as a partnership, although even if the IRS were
successful the Trust would not be subject to U.S. federal income tax. While not
certain, if the Trust is classified as a partnership, it should be eligible for
the election out of the partnership tax rules of subchapter K of the Code, under
Treasury Regulation Section 1.761-2. In mutual consideration for each holder's
purchase of a Trust Certificate, each holder of a Trust Certificate is deemed to
have consented to the making of such a protective election as of the date of
formation of the Trust. As a result of the election, each holder of a Trust
Certificate would be required to report its respective share of the items of
income, deductions and credits of the Trust on its respective U.S. federal
income tax return in a manner substantially similar to the U.S. federal income
tax reporting required under the grantor trust rules. However, if the Trust were
not eligible to make the election, the method of taxation of holders of Trust
Certificates could differ significantly from the treatment described in this
summary. Among those differences, (i) the Trust would be required to account for
its income and deductions at the Trust level, and to utilize a taxable year for
reporting purposes, (ii) income from the NSC Notes would be taxed under the
rules of the Code applicable to whole debt instruments rather than under the
"stripped bond" rules described above, and (iii) each holder would be required
to separately take into account such holder's distributive share of income and
deductions of the Trust. A holder would take into account its distributive share
of Trust income and deductions for each taxable year of the Trust in the
holder's taxable year which ends with or within the Trust's taxable year.
Prospective purchasers are urged to consult their tax advisers regarding the
U.S. federal income tax classification of the Trust.

     Adverse tax consequences might also result if the IRS takes a different
position than the position described above under "--Purchase and Holding of
Trust Certificates" with respect to the effect on holders of a potential
distribution to Amortizing Class Certificate holders of a portion of the payment
received by the Trust on an Optional Redemption Date or a Shortened Maturity
Date. For example, the IRS might treat the Amortizing Class Certificate as a
right to payments on the NSC Notes coupled with a separate agreement, in the
nature of a put option, between Amortizing Class Certificate holders, on the one
hand, and Residual Class Certificate holders, on the other hand. Under this
characterization, an Optional Redemption or Shortened Maturity Redemption would
be a taxable event. Moreover, the existence of a deemed put option might trigger
the Code's "straddle" rules, in which case, among other matters, gain or loss on
the sale of a Trust Certificate would be short-term capital gain or loss
regardless of the period during which the holder held the Trust Certificate.

Non-U.S. Holders

     A holder that is not a U.S. person and that is not subject to U.S. federal
income tax as a result of any direct or indirect connection to the United States
other than its ownership of a Trust Certificate will not be subject to United
States income or withholding tax, except as described below and under
"--Information Reporting and Backup Withholding," in respect of interest income
or gain on the NSC Notes if the holder provides an appropriate statement
(generally on IRS Form W-8), signed under penalties of perjury, identifying the
holder and stating, among other things, that the holder is not a U.S. person
(or, after December 31, 1999, if the holder satisfied applicable documentary
evidence requirements for establishing that it is not a U.S. person) and if the
holder is not a "10-percent shareholder" or related "controlled foreign
corporation" with respect to NSC. If these conditions are not met, a 30 percent
withholding tax will apply to interest income from the Trust Certificates,
unless an income tax treaty reduces or eliminates such tax or unless the
interest is effectively connected with the conduct of a trade or business within
the United States by such holder. In the latter case, such holder will be
subject to U.S. federal income tax with respect to all income from the NSC Notes
at regular rates applicable to U.S. taxpayers.

     A holder that is not a U.S. person may also be subject to U.S. federal
income taxation with respect to a Trust Certificate if it is a personal holding
company, a corporation that accumulates earnings to avoid U.S. taxes on
shareholders or a private foundation under the Code.

Information Reporting and Backup Withholding

     The Trustee will furnish or make available to each party registered during
such calendar year as a holder, such information as is required under the Code
or regulations under the Code to enable each holder to file its U.S. federal
income tax returns.

     Certain holders that are U.S. persons or that otherwise are subject to
United States federal income taxation on a net income basis in respect of the
Note ("U.S. holders") may be subject to a 31 percent backup withholding tax in
respect of distributions made on a Trust Certificate and proceeds from the sale
of a Trust Certificate to or through certain brokers if they do not provide
their taxpayer identification numbers (generally on IRS Form W-9). Persons who
are not U.S. holders may be required to comply with applicable certification
procedures to establish that they are not U.S. holders in order to avoid the
application of information reporting requirements and backup withholding tax.
Any amounts so withheld from distributions on the Trust Certificate would be
allowed as a credit against the holder's U.S. federal income tax liability, or
upon application by the holder to the IRS, would be refunded by the IRS to the
extent it exceeds such liability.

                              PLAN OF DISTRIBUTION

     Each broker or dealer that receives New Certificates for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such New Certificates. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker or dealer in connection with resales of New Certificates received in
exchange for Old Certificates where such Old Certificates were acquired as a
result of market-making activities or other trading activities. PSSA has agreed
that it will make this Prospectus, as amended or supplemented, available to any
broker or dealer for use in connection with any such resale for a period of one
year. In addition, until such date, all brokers or dealers effecting
transactions in the New Certificates may be required to deliver a prospectus.

     PSSA will not receive any proceeds from any sale of New Certificates by
brokers or dealers. New Certificates received by brokers or dealers for their
own account pursuant to the Exchange Offer may be sold from time to time in one
or more transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the New Certificates or a combination of such
methods of resale, at market prices prevailing at the time of resale, at prices
related to such prevailing market prices or negotiated prices. Any such resale
may be made directly to purchasers or to or through brokers or dealers who may
receive compensation in the form of commissions or concessions from any such
broker or dealer and/or the purchasers of any such New Certificates. Any broker
or dealer that resells New Certificates that were received by it for its own
account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such New Certificates may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit on any
such resale of New Certificates and any commissions or concessions received by
any such persons may be deemed to be underwriting compensation under the
Securities Act. The Letter of Transmittal states that by acknowledging that it
will deliver and by delivering a prospectus, a broker or dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act.

     Starting on the Expiration Date, PSSA will promptly send additional copies
of this Prospectus and any amendment or supplement to this Prospectus to any
broker or dealer that requests such documents in the Letter of Transmittal. PSSA
has agreed to pay all expenses incident to the Exchange Offer (including the
expenses of one counsel for the Holders of the Certificates) other than
commissions or concessions of any brokers or dealers and will indemnify the
Holders of the New Certificates (including any broker or dealers) against
certain liabilities, including liabilities under the Securities Act.

                                  LEGAL MATTERS

     The validity of the New Certificates and certain United States federal
income taxation matters will be passed upon for the Trust by Cleary, Gottlieb,
Steen & Hamilton, New York, New York.

                                     PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.  Indemnification of Directors and Officers.

     PSSA's Bylaws provide that PSSA shall indemnify each of its directors and
officers who was or is a party or is threatened to be made a party to any
threatened, pending or contemplated action, suit or proceeding, whether civil,
criminal, administrative or investigative by reason of the fact that he is or
was a director or officer of PSSA other than an action by or in the right of
PSSA (for which PSSA may indemnify such persons under certain circumstances).

     Section 145 of the Delaware General Corporation Law (the "GCL") provides as
follows:

     "(a) A corporation may indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

     (b) A corporation may indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the corporation to procure a judgment in its favor by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery or such other court
shall deem proper.

     (c) To the extent that a director, officer, employee or agent of a
corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in subsections (a) and (b) of this
section, or in defense of any claim, issue or matter therein, he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith.

     (d) Any indemnification under subsections (a) and (b) of this section
(unless ordered by a court) shall be made by the corporation only as authorized
in the specific case upon a determination that indemnification of the director,
officer, employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in subsections (a) and (b). Such
determination shall be made (1) by a majority vote of the board of directors who
are not parties to such action, suit or proceeding, even though less than a
quorum, or (2) if there are no such directors, or if such directors so direct,
by independent legal counsel in a written opinion, or (3) by the stockholders.

     (e) Expenses (including attorneys' fees) incurred by an officer or director
in defending any civil, criminal, administrative, or investigative action, suit
or proceeding may be paid by the corporation in advance of the final disposition
of such action, suit or proceeding upon receipt of undertaking by or on behalf
of such director or officer to repay such amount if it shall ultimately be
determined that he is not entitled to be indemnified by the corporation as
authorized in this section. Such expenses (including attorneys' fees) incurred
by other employees and agents may be so paid upon such terms and conditions, if
any, as the board of directors deems appropriate.

     (f) The indemnification and advancement of expenses provided by, or granted
pursuant to, the other subsections of this section shall not be deemed exclusive
of any other rights to which those seeking indemnification or advancement of
expenses may be entitled under any bylaw, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in another capacity while holding such office.

     (g) A corporation shall have power to purchase and maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against any liability asserted against him
and incurred by him in any such capacity, or arising out of his status as such,
whether or not the corporation would have the power to indemnify him against
such liability under this section.

     (h) For purposes of this section, references to "the corporation" shall
include, in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger which, if its separate existence had continued, would have had power and
authority to indemnify its directors, officers, and employees or agents, so that
any person who is or was a director, officer, employee or agent for such
constituent corporation, or is or was serving at the request of such constituent
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, shall stand in the same
position under this section with respect to the resulting or surviving
corporation as he would have with respect to such constituent corporation if its
separate existence had continued.

     (i) For purposes of this section, references to "other enterprises" shall
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the corporation" shall include any
service as a director, officer, employee or agent of the corporation which
imposes duties on, or involves services by, such director, officer, employee, or
agent with respect to an employee benefit plan, its participants, or
beneficiaries; and a person who acted in good faith and in a manner he
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan shall be deemed to have acted in a manner "not
opposed to the best interests of the corporation" as referred to in this
section.

     (j) The indemnification and advancement of expenses provided by, or granted
pursuant to, this section shall, unless otherwise provided when authorized or
ratified, continue as to a person who has ceased to be a director, officer,
employee or agent and shall inure to the benefit of the heirs, executors and
administrators of such a person.

     (k) The Court of Chancery is hereby vested with exclusive jurisdiction to
hear and determine all actions for advancement of expenses or indemnification
brought under this section or under any bylaw, agreement, vote of stockholders
or disinterested directors, or otherwise. The Court of Chancery may summarily
determine a corporation's obligation to advance expenses (including attorneys'
fees)."

     The Amended and Restated Certificate of Incorporation also limit the
personal liability of directors to PSSA and its stockholders for monetary
damages resulting from certain breaches of the directors' fiduciary duties. The
Amended and Restated Certificate of Incorporation of PSSA provide as follows:

     "No director of the Corporation shall be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director; provided that the provisions of this Article Eleventh shall
not eliminate or limit the liability of a director (a) for any breach of the
Director's duty of loyalty to the Corporation and to its stockholders, (b) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the General Corporation Law
of the State of Delaware or (iv) for any transaction from which such director
derived any improper personal benefit. If the GCL is amended after the filing of
this Amended and Restated Certificate of Incorporation so as to authorize
corporate action further eliminating or limiting the personal liability of
directors, then the liability of each director of the Corporation shall be
eliminated or limited to the fullest extent permitted by the law of the State of
Delaware as the same exists from time to time. Any repeal or modification of
this Article Eleventh by the stockholders of the Corporation shall not adversely
affect any elimination or limitation on the personal liability of a director
existing at the time of such repeal or modification."

                        l0(a)(3) of the Securities Act of 1933;

                  (ii)  To reflect in the prospectus any facts or events arising
                        after the effective date of the registration (or the
                        most recent post-effective amendment thereof) which,
                        individually or in the aggregate, represent a
                        fundamental change in the information set forth in the
                        registration statement. Notwithstanding the foregoing,
                        any increase or decrease in volume of securities offered
                        (if the total dollar value of securities offered would
                        not exceed that which was registered) and any deviation
                        from the low or high and of the estimated maximum
                        offering range may be reflected in the form of
                        prospectus filed with the Commission pursuant to Rule
                        424(b) if, in the aggregate, the changes in volume and
                        price represent no more than 20 percent change in the
                        maximum aggregate offering price set forth in the
                        "Calculation of Registration Fee" table in the 
                        effective registration statement;

                  (iii) To include any material information with respect to the
                        plan of distribution not previously disclosed in the
                        registration statement or any material change to such
                        information in the registration statement;

                        provided, however, that paragraphs (a)(1)(i) and
                        (a)(1)(ii) shall not apply if the registration 
                        statement is on Form S-3, Form S-8, or Form F-3 and the
                        information required to be included in a post-effective
                        amendment by those paragraphs is contained in periodic
                        reports filed by the registrants pursuant to section 13
                        or section 15(d) of the Securities Exchange Act of 1934
                        that are incorporated by reference in the registration
                        statement.


     (2) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.


     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.


     The undersigned registrants hereby undertake that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plans annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.


     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrants, pursuant to the foregoing provisions, or otherwise, the registrants
have been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrants of expenses incurred or paid by a director, officer or controlling
person of the registrants in the successful defense of any action, suit or
proceeding) is asserted by any such director, officer or controlling person in
connection with the securities being registered, the registrants will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question of whether or not
such indemnification is against public policy as expressed in the Securities Act
of 1933 and will be governed by the final adjudication of such issue.


     The undersigned registrants hereby undertake to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.


     The undersigned registrants hereby undertake to supply by means of a
post-effective amendment all information concerning a transaction, and PSSA
being acquired involved therein, that was not the subject of and included in the
registration statement when it became effective.


                                   SIGNATURES


                  Pursuant to the requirements of the Securities Act, the

Ladies and Gentlemen:

     Re:  Prudential Securities Structured Assets, Inc. and Receipts on
          Corporate Securities Trust, Series NSC 1998-1 Registration Statement
          on Form S-4 (File No. 333-60185)
          ---------------------------------------------------------------------


     We have acted as your counsel in connection with the above-referenced
Registration Statement on Form S-4, as amended (the "Registration Statement"),
initially filed on July 30, 1998 with the Securities and Exchange Commission
(the "Commission") pursuant to the Securities Act of 1933, as amended (the
"Act"), in respect of the Receipts of Corporate Securities, Series NSC 1998-1,
Amortizing Class Certificates (the "New Certificates"), to be offered in
exchange (the "Exchange") for all outstanding Receipts of Corporate Securities,
NSC 1998-1, Amortizing Class Certificates (the "Old Certificates") as described
in the form of prospectus contained therein (the "Prospectus"). The New
Certificates will be issued by Receipts on Corporate Securities Trust, Series
NSC 1998-1 (the "Trust"). The Trust was created pursuant to a Base Trust
Agreement dated as of August 28, 1997, as amended by Base Amendment No. 1 dated
as of February 27, 1998 and as supplemented by the Series NSC 1998-1 Supplement
dated as of April 13, 1998 (together, the "Trust Agreement") between Prudential
Securities Structured Assets, Inc., as depositor ("PSSA"), and The Bank of New
York, a New York banking corporation, as trustee (the "Trustee").

     In arriving at the opinions expressed below, we have reviewed the
Registration Statement as filed with the Commission and the exhibits thereto. In
addition, we have reviewed the originals or copies certified or otherwise
identified to our satisfaction of all such corporate records of PSSA, the Trust,
the Trustee and such other instruments and other certificates of public
officials, officers and representatives of PSSA and the Trustee, and such other
persons, and we have made such investigations of law, as we have deemed
appropriate as a basis for the opinions expressed below. In rendering the
opinions expressed below, we have assumed that the signatures on all documents
that we have reviewed are genuine, we have relied upon the facts stated in the
Prospectus, and we have assumed that the New Certificates will conform in all
material respects to the description thereof set forth in the Prospectus.

     Based upon and subject to the foregoing, and subject to the further
qualifications set forth below, it is our opinion that:

     1. When New Certificates, in the form filed as an exhibit to the
Registration Statement, have been duly executed and authenticated in accordance
with the Trust Agreement, and duly issued and delivered by the Trustee in
exchange for an equal Certificate Principal Balance of Old Certificates pursuant
to the terms of the Registration Rights Agreement in the form filed as an
exhibit to the Registration Statement, such New Certificates will be legal,
valid, binding and enforceable obligations of the Trust, entitled to the
benefits of the Trust Agreement, subject to applicable bankruptcy, insolvency
and similar laws affecting creditors' rights generally and to general principles
of equity.

     2. For U.S. federal income tax purposes, the Trust will not be treated as
an association taxable as a corporation (or a publicly traded partnership
treated as an association).

     3. The Exchange will not be a taxable event for U.S. federal income tax
purposes.

     The foregoing opinion in numbered paragraph 1 is limited to the law of the
State of New York. The foregoing opinions in numbered paragraphs 2 and 3 are
based on the Internal Revenue Code of 1986, as amended, U.S. Treasury
regulations promulgated thereunder, and administrative and judicial
interpretations thereof, all as of the date hereof and all of which are subject
to change, possibly on a retroactive basis. In rendering the opinions in
paragraphs 2 and 3, we are expressing our views only as to the federal income
tax laws of the United States of America.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to this firm under the heading
"Legal Matters" in the Prospectus included in the Registration Statement. In
giving such consent, we do not thereby admit that we are "experts" within the
meaning of the Act or the rules and regulations of the Securities and Exchange
Commission issued thereunder with respect to any part of the Registration
Statement, including this exhibit.

                                    Very truly yours,

                                    CLEARY, GOTTLIEB, STEEN & HAMILTON

               PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

     Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Trust the aggregate Certificate Principal
Balance of Old Certificates indicated above. Subject to, and effective upon, the
acceptance for exchange of the Old Certificates tendered hereby, the undersigned
hereby sells, assigns and transfers to, or upon the order of, the Trust all
right, title and interest in and to such Old Certificates as are being tendered
hereby.

     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Old
Certificates tendered hereby and that the Trust will acquire good and
unencumbered title thereto, free and clear of all liens, restrictions, charges
and encumbrances and not subject to any adverse claim when the same are accepted
by the Trust. The undersigned hereby further represents that any New
Certificates acquired in exchange for Old Certificates tendered hereby will have
been acquired in the ordinary course of business of the person receiving such
New Certificates, whether or not such person is the undersigned, that neither
the holder of such Old Certificates nor any such other person is engaged in, or
intends to engage in a distribution of such New Certificates, or has an
arrangement or understanding with any person to participate in the distribution
of such New Certificates, and that neither the holder of such Old Certificates
nor any such other person is an "affiliate," as defined in Rule 405 under the
Securities Act of 1933, as amended (the "Securities Act"), of the Company.

     The undersigned also acknowledges that this Exchange Offer is being made
based upon the understanding of the Company of an interpretation by the staff of
the Securities and Exchange Commission (the "Commission") as set forth in
no-action letters issued to third parties, including Exxon Capital Holdings
Corporation, SEC No-Action Letter (available April 13, 1989), Morgan Stanley &
Co. Incorporated, SEC No-Action Letter (available June 5, 1991) and Shearman &
Sterling, SEC No-Action Letter (available July 2, 1993), that the New
Certificates issued in exchange for the Old Certificates pursuant to the
Exchange Offer may be offered for resale, resold and otherwise transferred by
holders thereof (other than a broker-dealer who acquires such New Certificates
directly from the Trust or the Company for resale pursuant to Rule 144A under
the Securities Act or any other available exemption under the Securities Act or
any such holder that is an "affiliate" of the Company within the meaning of Rule
405 under the Securities Act), without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such New
Certificates are acquired in the ordinary course of such holders' business and
such holders are not engaged in, and do not intend to engage in, a distribution
of such New Certificates and have no arrangement with any person to participate
in the distribution of such New Certificates. If a holder of Old Certificates is
engaged in or intends to engage in a distribution of the New Certificates or has
any arrangement or understanding with respect to the distribution of the New
Certificates to be acquired pursuant to the Exchange Offer, such holder may not
rely on the applicable interpretations of the staff of the Commission and must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any secondary resale transaction. If the
undersigned is a broker-dealer that will receive New Certificates for its own
account in exchange for Old Certificates, it represents that the Old
Certificates to be exchanged for the New Certificates were acquired by it as a
result of market-making activities or other trading activities and acknowledges
that it will deliver a prospectus in connection with any resale of such New
Certificates; however, by so acknowledging and by delivering a prospectus, the
undersigned will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

     The undersigned will, upon request, execute and deliver any additional
documents deemed by the Trust to be necessary or desirable to complete the sale,
assignment and transfer of the Old Certificates tendered hereby. All authority
conferred or agreed to be conferred in this Letter and every obligation of the
undersigned hereunder shall be binding upon the successors, assigns, heirs,
executors, administrators, trustees in bankruptcy and legal representatives of
the undersigned and shall not be affected by, and shall survive, the death or
incapacity of the undersigned. This tender may be withdrawn only in accordance
with the procedures set forth in "The Exchange Offer--Withdrawal of Tenders"
section of the Prospectus.

     Unless otherwise indicated herein in the box entitled "Special Issuance
Instructions" below, please deliver the New Certificates (and, if applicable,
substitute certificates representing Old Certificates for any Old Certificates
not exchanged) in the name of the undersigned. Similarly, unless otherwise
indicated under the box entitled "Special Delivery Instructions" below, please
send the New Certificates (and, if applicable, substitute certificates
representing Old Certificates for any Old Certificates not exchanged) to the
undersigned at the address shown above in the box entitled "Description of Old
Certificates".

     THE UNDERSIGNED, BY COMPLETING THE BOX ENTITLED "DESCRIPTION OF OLD
CERTIFICATES" ABOVE AND SIGNING THIS LETTER, WILL BE DEEMED TO HAVE TENDERED THE
OLD CERTIFICATES AS SET FORTH IN SUCH BOX ABOVE.

                                  INSTRUCTIONS

        Forming Part of the Terms and Conditions of the Offer to Exchange
      Receipts of Corporate Securities, Series NSC 1998-1, Amortizing Class
    which have been registered under the Securities Act of 1933, as amended,
                           for any and all Outstanding
      Receipts of Corporate Securities, Series NSC 1998-1, Amortizing Class
          by Receipts on Corporate Securities Trust, Series NSC 1998-1

1.   Delivery of this Letter and Old Certificates; Guaranteed Delivery 
Procedures.

     This Letter is to be completed by holders of Old Certificates if
certificates are to be forwarded herewith. Certificates for all physically
tendered Old Certificates as well as a properly completed and duly executed
Letter of Transmittal (or facsimile thereof) and any other documents required by
this Letter, must be received by the Exchange Agent at the address set forth
herein on or prior to the Expiration Date, or the tendering holder must comply
with the guaranteed delivery procedures set forth below. Old Certificates
tendered hereby must be in denominations of Certificate Principal Balance of
$250,000 and integral multiples of $1.00 in excess thereof.

     Holders of Old Certificates whose certificates for Old Certificates are not
immediately available or who cannot deliver their certificates and all other
required documents to the Exchange Agent on or prior to the Expiration Date may
tender their Old Certificates pursuant to the guaranteed delivery procedures set
forth in "The Exchange Offer--Guaranteed Delivery Procedures" section of the
Prospectus. Pursuant to such procedures, (i) such tender must be made through an
Eligible Institution (as defined below), (ii) prior to the Expiration Date, the
Exchange Agent must receive from such Eligible Institution a properly completed
and duly executed Letter of Transmittal (or facsimile thereof) and Notice of
Guaranteed Delivery, substantially in the form provided by the Trust (by
facsimile transmission, mail or hand delivery), setting forth the name and
address of the holder of Old Certificates and the amount of Old Certificates
tendered, stating that the tender is being made thereby and guaranteeing that
within three New York Stock Exchange ("NYSE") trading days after the date of
execution of the Notice of Guaranteed Delivery, the certificates for all
physically tendered Old Certificates and any other documents required by this
letter will be deposited by the Eligible Institution with the Exchange Agent,
and (iii) the certificates for all physically tendered Old Certificates, in
proper form for transfer, and all other documents required by this Letter, are
received by the Exchange Agent within three NYSE trading days after the date of
execution of the Notice of Guaranteed Delivery.

     The method of delivery of this Letter, the Old Certificates and all other
required documents is at the election and risk of the tendering holders, but the
delivery will be deemed made only when actually received or confirmed by the
Exchange Agent. If Old Certificates are sent by mail, it is suggested that the
mailing be made sufficiently in advance of the Expiration Date to permit
delivery to the Exchange Agent prior to 5:00 p.m., New York City time, on the
Expiration Date.

     See "The Exchange Offer" section of the Prospectus.

2.   Partial Tenders.

     If less than all of the Old Certificates evidenced by a submitted
certificate are to be tendered, the tendering holder(s) should fill in the
aggregate principal amount of Old Certificates to be tendered in the box above
entitled "Description of Old Certificates--Principal Amount Tendered". A
reissued certificate representing the balance of nontendered Old Certificates
will be sent to such tendering holder, unless otherwise provided in the
appropriate box on this Letter, promptly after the Expiration Date. All of the
Old Certificates delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise indicated.

3.   Signatures of this Letter; Bond Powers and Endorsements; Guarantee of
Signatures.

     If this Letter is signed by the registered holder of the Old Certificates
tendered hereby, the signature must correspond exactly with the name as written
on the face of the certificates without any change whatsoever.

     If any tendered Old Certificates are owned of record by two or more joint
owners, all such owners must sign this Letter.

     If any tendered Old Certificates are registered in different names on
several certificates, it will be necessary to complete, sign and submit as many
separate copies of this Letter as there are different registrations of
certificates.

     When this Letter is signed by the registered holder of the Old Certificates
specified herein and tendered hereby, no endorsements of certificates or
separate bond powers are required. If, however, the New Certificates are to be
issued, or any untendered Old Certificates are to be reissued, to a person other
than the registered holder, then endorsements of any certificates transmitted
hereby or separate bond powers are required. Signatures on such certificates
must be guaranteed by an Eligible Institution.

     If this Letter is signed by a person other than the registered holder of
any certificates specified herein, such certificates must be endorsed or
accompanied by appropriate bond powers, in either case signed exactly as the
name of the registered holder appears on the certificates and the signatures on
such certificates must be guaranteed by an Eligible Institution.

     If this Letter or any certificates or bond powers are signed by trustees,
executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and, unless waived by the Trust, proper
evidence satisfactory to the Trust of their authority to so act must be
submitted.

     ENDORSEMENTS ON CERTIFICATES FOR OLD CERTIFICATES OR SIGNATURES ON BOND
POWERS REQUIRED BY THIS INSTRUCTION 3 MUST BE GUARANTEED BY A FIRM WHICH IS A
MEMBER OF A REGISTERED NATIONAL SECURITIES EXCHANGE OR A MEMBER OF THE NATIONAL
ASSOCIATION OF SECURITIES DEALERS, INC., BY A COMMERCIAL BANK OR TRUST COMPANY
HAVING AN OFFICE OR CORRESPONDENT IN THE UNITED STATES OR BY AN "ELIGIBLE
GUARANTOR" INSTITUTION WITHIN THE MEANING OF RULE 17AD-15 UNDER THE SECURITIES
EXCHANGE ACT OF 1934 (AN "ELIGIBLE INSTITUTION").

     SIGNATURES ON THIS LETTER NEED NOT BE GUARANTEED BY AN ELIGIBLE
INSTITUTION, PROVIDED THE OLD CERTIFICATES ARE TENDERED (I) BY A REGISTERED
HOLDER OF OLD CERTIFICATES WHO HAS NOT COMPLETED THE BOX ENTITLED "SPECIAL
ISSUANCE INSTRUCTIONS" OR "SPECIAL DELIVERY INSTRUCTIONS" ON THIS LETTER, OR
(II) FOR THE ACCOUNT OF AN ELIGIBLE INSTITUTION.

4.   Special Issuance and Delivery Instructions.

     Tendering holders of Old Certificates should indicate in the applicable box
the name and address to which New Certificates issued pursuant to the Exchange
Offer and/or substitute certificates evidencing Old Certificates not exchanged
are to be issued or sent, if different from the name or address of the person
signing this Letter. In the case of issuance in a different name, the employer
identification or social security number of the person named must also be
indicated. If no such instructions are given, such Old Certificates not
exchanged will be returned to the name or address of the person signing this
Letter.

5.   Tax Identification Number.

     Federal income tax law generally requires that a tendering holder whose Old
Certificates are accepted for exchange must provide the Trustee (as payor) with
such Holder's correct Taxpayer Identification Number ("TIN") on Substitute Form
W-9 below, which, in the case of a tendering holder who is an individual, is his
or her social security number. If the Trustee is not provided with the current
TIN or an adequate basis for an exemption, such tendering holder may be subject
to a $50 penalty imposed by the Internal Revenue Service. In addition, delivery
of New Certificates to such tendering holder may be subject to backup
withholding in an amount equal to 31% of all reportable payments made after the
exchange. If withholding results in an overpayment of taxes, a refund may be
obtained.

     Exempt holders of Old Certificates (including, among others, all
corporations and certain foreign individuals) are not subject to these backup
withholding and reporting requirements. See the enclosed Guidelines of
Certification of Taxpayer Identification Number on Substitute Form W-9 (the "W-9
Guidelines") for additional instructions.

     To prevent backup withholding, each tendering holder of Old Certificates
must provide its correct TIN by completing the "Substitute Form W-9" set forth
below, certifying that the TIN provided is correct (or that such holder is
awaiting a TIN) and that (i) the holder is exempt from backup withholding, (ii)
the holder has not been notified by the Internal Revenue Service that such
holder is subject to a backup withholding as a result of a failure to report all
interest or dividends or (iii) the Internal Revenue Service has notified the
holder that such holder is no longer subject to backup withholding. If the
tendering holder of Old Certificates is a nonresident alien or foreign entity
not subject to backup withholding, such holder must give the Trustee a completed
Form W-8, Certificate of Foreign Status. These forms may be obtained from the
Exchange Agent. If the Old Certificates are in more than one name or are not in
the name of the actual owner, such holder should consult the W-9 Guidelines for
information on which TIN to report. If such holder does not have a TIN, such
holder should consult the W-9 Guidelines for instructions on applying for a TIN,
check the box in Part 2 of the Substitute Form W-9 and write "applied for" in
lieu of its TIN. Note: checking this box and writing "applied for" on the form
means that such holder has already applied for a TIN or that such holder intends
to apply for one in the near future. If such holder does not provide its TIN to
the Trustee within 60 days, backup withholding will begin and continue until
such holder furnishes its TIN to the Trustee.

6.   Transfer Taxes.

     The Company will pay all transfer taxes, if any, applicable to the transfer
of Old Certificates to it or its order pursuant to the Exchange Offer. If,
however, New Certificates and/or substitute Old Certificates not exchanged are
to be delivered to, or are to be registered or issued in the name of, any person
other than the registered holder of the Old Certificates tendered hereby, or if
tendered Old Certificates are registered in the name of any person other than
the person signing this Letter, or if a transfer tax is imposed for any reason
other than the transfer of Old Certificates to the Trust or its order pursuant
to the Exchange Offer, the amount of any such transfer taxes (whether imposed on
the registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such taxes or exemption therefrom
is not submitted herewith, the amount of such transfer taxes will be billed
directly to such tendering holder.

     EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT IS NOT NECESSARY FOR TRANSFER
TAX STAMPS TO BE AFFIXED TO THE OLD CERTIFICATES SPECIFIED IN THIS LETTER.

7.   Waiver of Conditions.

     The Trust reserves the absolute right to waive satisfaction of any or all
conditions enumerated in the Prospectus.

8.   No Conditional Tenders.

     No alternative, conditional, irregular or contingent tenders will be
accepted. All tendering holders of Old Certificates, by execution of this
Letter, shall waive any right to receive notice of the acceptance of their Old
Certificates for exchange.

     None of the Trustee, the Exchange Agent, PSSA or any other person is
obligated to give notice of any defect or irregularity with respect to any
tender of Old Certificates nor shall any of them incur any liability for failure
to give any such notice.

9.   Mutilated, Lost, Stolen or Destroyed Old Certificates.

     Any holder whose Old Certificates have been mutilated, lost, stolen or
destroyed should contact the Exchange Agent at the address indicated above for
further instructions.

10.  Requests for Assistance or Additional Copies.

     Questions relating to the procedure for tendering, as well as requests for
additional copies of the Prospectus and this Letter, may be directed to the
Exchange Agent, at the address and telephone number indicated above.
