     NOW, THEREFORE, WITNESSETH:

     For and in  consideration  of the  premises  and  other  good and  valuable
consideration, the sufficiency and receipt of which are hereby acknowledged, and
the purchase of the Securities by the Holders  thereof,  it is mutually  agreed,
for the equal and  proportionate  benefit of all Holders of the  Securities,  as
follows:

                                   ARTICLE ONE
                       INCORPORATION OF PREVIOUS DOCUMENTS

                SECTION 101. Incorporation of Previous Documents.

     This Tenth  Supplemental  Indenture is a supplemental  indenture within the
meaning of the Indenture and shall be read  together  therewith,  and shall have
the same effect as though all the  provisions  thereof and hereof were contained
in one instrument.  Unless otherwise expressly  provided,  the provisions of the
Indenture are incorporated herein by reference.

     SECTION 102. Definitions.

     Unless  otherwise  provided  herein,  the terms used herein  shall have the
meanings ascribed to such terms in the Indenture.

     SECTION 103. Governing Law.

     This Tenth Supplemental  Indenture,  the Indenture and the Securities shall
be governed by and  construed  in  accordance  with the laws of the State of New
York.

     SECTION 104. Trustee.

     The Trustee makes no  representation  as to the validity or  sufficiency of
this Tenth Supplemental Indenture,  except as to the satisfaction of the Trustee
with the form hereof.  The recitals and statements herein are deemed to be those
of the parties hereto other than the Trustee.


                                   ARTICLE TWO
                                 TWNYH GUARANTY

     The TWNYH Guaranty  provided for in this Article Two shall become effective
upon execution and delivery of this Tenth Supplemental  Indenture by each of the
parties hereto.

     For value received,  TWNYH and, subject to the terms of the Indenture,  its
successors  and assigns,  hereby fully and  unconditionally  guarantees  to each
Holder  of

                                       3


Securities  Outstanding  as of the date  hereof  and any  Securities  heretofore
issued and  Outstanding  which  reference  the  applicability  of this  Guaranty
(collectively,  the "Guaranteed Securities"),  and to the Trustee for itself and
on behalf of each such Holder,  the due and punctual payment of the principal of
(and premium if any) and interest on such Guaranteed Securities, when and as the
same become due and payable,  whether at Stated  Maturity,  upon  redemption  or
repayment, upon declaration of acceleration or otherwise, according to the terms
of the Guaranteed Securities and of the Indenture. In case of the failure of TWE
or any  successor  thereto  to  punctually  pay any such  principal,  premium or
interest,  TWNYH hereby agrees to immediately  cause any such payment to be made
punctually when and as the same shall become due and payable,  whether at Stated
Maturity,  upon  redemption or repayment,  upon  declaration of  acceleration or
otherwise, as if such payment were made by TWE.

     TWNYH  hereby  agrees that as long as this  Article  Two is in effect,  its
obligations  hereunder  and  under  the  Indenture  shall be  unconditional  and
absolute,  irrespective  of the identity of TWE,  the  validity,  regularity  or
enforceability  of any such  Securities  or the  Indenture,  the  absence of any
action to enforce the same,  the granting of any waiver or consent by the Holder
of any such Securities with respect to any provisions  thereof,  the recovery of
any  judgment  against  TWE or any  action to  enforce  the  same,  or any other
circumstance which might otherwise  constitute a legal or equitable discharge or
defense of a guarantor.  TWNYH hereby waives diligence,  presentment,  demand of
payment,  filing of claims with a court in the event of insolvency or bankruptcy
of TWE,  any right to require that a proceeding  be brought  first  against TWE,
protest,  notice and all demands whatsoever,  and covenants that as long as this
Article Two is in effect,  this TWNYH Guaranty will not be discharged  except by
complete payment of the payment and other obligations contained in such Security
or in this Article Two.

     TWNYH  acknowledges  and agrees for the  benefit  of the  Trustee  and such
Holders  that the Trustee  and such  Holders (in the case of an Event of Default
under Section 501(1) or (2) of the  Indenture)  may directly and  simultaneously
proceed against TWNYH for the enforcement of this TWNYH Guaranty and against TWE
(as  Obligor).  The  obligations  of  TWNYH  hereunder  are  independent  of the
obligations  of TWE under the Guaranteed  Securities  and the  Indenture,  and a
separate action or actions may be brought and prosecuted against TWNYH hereunder
whether or not (i) an action or proceeding  is brought  against TWE, (ii) TWE is
joined in any such action or  proceeding  against  TWNYH or (iii) the Trustee or
such Holders have taken any action to collect or attempted to otherwise  collect
such obligations from TWE or any other Person liable therefor.

     Anything in this  Article Two to the contrary  notwithstanding,  this TWNYH
Guaranty is and shall be deemed to be a guaranty of payment,  and not a guaranty
of collection.

     If the Trustee or the Holder of any Guaranteed  Security is required by any
court or  otherwise  to return to TWE or any  custodian,  receiver,  liquidator,
trustee,

                                       4


sequestrator  or other  similar  official  acting in relation to TWE, any amount
paid to the Trustee or such Holder in respect of such Guaranteed Security,  this
TWNYH Guaranty,  to the extent  theretofore  discharged,  shall be reinstated in
full force and effect.  TWNYH further agrees,  to the fullest extent that it may
lawfully  do so,  that,  as  between  itself,  on the one hand,  and  Holders of
Guaranteed  Securities  and the Trustee,  on the other hand, the maturity of the
obligations  guaranteed  hereby may be  accelerated  to the extent  provided  in
Article  Five  of  the   Indenture   for   purposes  of  this  TWNYH   Guaranty,
notwithstanding  any stay,  injunction or other  prohibition  existing under any
applicable  bankruptcy  law  preventing  such  acceleration  in  respect  of the
obligations guaranteed hereby.

     No reference herein to the Indenture,  and no provision of this Article Two
or of the  Indenture,  shall  alter or  impair  this  TWNYH  Guaranty,  which is
absolute and unconditional,  as to the payment of the principal (and premium, if
any) and  interest  owing in respect of the  Securities  referring to this TWNYH
Guaranty.

                                  ARTICLE THREE
                  ADDITION OF TWNYH AS A PARTY TO THE INDENTURE

     By execution  of this Tenth  Supplemental  Indenture,  TWNYH agrees that it
shall be a party to,  and shall be  subject  to,  bound by and  entitled  to the
benefits of, the Indenture as supplemented by this Tenth Supplemental  Indenture
until such time, if any, as the TWNYH Guaranty  shall be terminated  pursuant to
Article Two hereof.

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

                                     * * * *

                                       5



     IN WITNESS WHEREOF,  the parties hereto have caused this Tenth Supplemental
Indenture to be duly executed by their  respective  officers or agents as of the
day and year first above written.
