execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

         (c) The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining the
Holders of Registered Securities of any series entitled to give or take any
request, demand, authorization, direction, notice, consent, waiver or other
action, or to vote on any action, authorized or permitted to be given or taken
by Holders of Securities of such series. If not set by the Company prior to the
first solicitation of a Holder of Securities of such series made by any Person
in respect of any such action, or, in the case of any such vote, prior to such
vote, the record date for any such action or vote shall be the 30th day (or, if
later, the date of the most recent list of Holders required to be provided
pursuant to Section 701) prior to such first solicitation or vote, as the case
may be. With regard to any record date for action to be taken by the Holders of
one or more series of Securities, only the Holders of Securities of such series
on such date (or their duly designated proxies) shall be entitled to give or
take, or vote on, the relevant action.

         (d) The principal amount and serial numbers of Registered Securities
held by any Person, and the date of holding the same, shall be proved by the
Security Register.

         (e) The principal amount and serial numbers of Bearer Securities held
by any Person, and the date of holding the same, may be proved by the production
of such Bearer Securities or by a certificate executed, as depositary, by any
trust company, bank, banker or other depositary, wherever situated, if such
certificate shall be deemed by the Trustee to be satisfactory, showing that at
the date therein mentioned such Person had on deposit with such depositary, or
exhibited to it, the Bearer Securities therein described; or such facts may be
proved by the certificate or affidavit of the Person holding such Bearer
Securities, if such certificate or affidavit is deemed by the Trustee to be
satisfactory. The Trustee and the Company may assume that such ownership of any
Bearer Security continues until (1) another certificate or affidavit bearing a

                                     10

<PAGE>

later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding. The principal amount and
serial numbers of Bearer Securities held by any Person, and the date of holding
the same, may also be proved in any other manner which the Trustee deems
sufficient.

         (f) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made upon
such Security. Any Holder or subsequent Holder may revoke the request, demand,
authorization, direction, notice, consent, waiver or other Act as to his
Security or portion of his Security; provided, however, that such revocation
shall be effective only if the Trustee receives notice of such revocation before
the date the Act becomes effective.

         (g) Without limiting the foregoing, a Holder entitled hereunder to give
or take any action hereunder with regard to any particular Security may do so
with regard to all or any part of the principal amount of such Security or by
one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any different part of such principal amount.

         Section 1.05.    NOTICES, ETC., TO TRUSTEE AND COMPANY.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Company shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with the Trustee at its Corporate Trust Office,
         Attention: Corporate Trust Department, or

                  (2) the Company by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and mailed, first-class postage
         prepaid, to the Company addressed to it at the address of its principal
         office specified in the first paragraph of this Indenture, to the
         attention of its Treasurer, or at any other address previously
         furnished in writing to the Trustee by the Company; and in the case of
         Bearer Securities, at the address of an office or agency located
         outside the United States maintained by the Company in accordance with
         Section 1002.

         Section 1.06.    NOTICE TO HOLDERS OF SECURITIES; WAIVER.

         Except as otherwise expressly provided herein, where this Indenture
provides for notice to Holders of Securities of any event,

                  (1) such notice shall be sufficiently given to Holders of
         Registered Securities if in writing and mailed, first-class postage
         prepaid, to each Holder of a Registered Security affected by such
         event, at the address of such Holder as it appears in the Security

                                     11

<PAGE>

         Register, not later than the latest date, and not earlier than the
         earliest date, prescribed for the giving of such notice; and

                  (2) such notice shall be sufficiently given to Holders of
         Bearer Securities if published in an Authorized Newspaper in The City
         of New York and in such other city or cities as may be specified in
         such Securities on a Business Day at least twice, the first such
         publication to be not earlier than the earliest date, and not later
         than the latest date, prescribed for the giving of such notice.

         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice to
Holders of Registered Securities by mail, then such notification as shall be
made with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. In any case where notice to Holders of
Registered Securities is given by mail, neither the failure to mail such notice,
nor any defect in any notice so mailed, to any particular Holder of a Registered
Security shall affect the sufficiency of such notice with respect to other
Holders of Registered Securities or the sufficiency of any notice to Holders of
Bearer Securities given as provided herein.

         In case by the reason of the suspension of publication of any
Authorized Newspaper or Authorized Newspapers or by reason of any other cause it
shall be impracticable to publish any notice to Holders of Bearer Securities as
provided above, then such notification to Holders of Bearer Securities as shall
be given with the approval of the Trustee shall constitute sufficient notice to
such Holders for every purpose hereunder. Neither the failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice to Holders
of Registered Securities given as provided herein.

         Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders of Securities shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

         Section 1.07.    LANGUAGE OF NOTICES, ETC.

         Any request, demand, authorization, direction, notice, consent or
waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of the
country of publication.

         Section 1.08.    CONFLICT WITH TRUST INDENTURE ACT.

         If any provision hereof limits, qualifies or conflicts with a provision
of the Trust Indenture Act that is required under the Trust Indenture Act to be
a part of and govern this Indenture or any other provision of this Indenture
that is required to be in this Indenture by the Trust Indenture Act, such
required provision shall control. If any provision of this Indenture modifies or
excludes any provision of the Trust Indenture Act that may be so modified or
excluded, the latter provision shall be deemed to apply to this Indenture as so
modified or to be excluded, as the case may be.

         Section 1.09.    EFFECT OF HEADINGS AND TABLE OF CONTENTS.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

         Section 1.10.    SUCCESSORS AND ASSIGNS.

         All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

         Section 1.11.    SEPARABILITY CLAUSE.

         In case any provision in this Indenture or the Securities or coupons
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

         Section 1.12.    BENEFITS OF INDENTURE.

         Nothing in this Indenture or the Securities or coupons, express or
implied, shall give to any Person, other than the parties hereto, their
successors hereunder and the Holders of Securities and coupons, any benefit or
any legal or equitable right, remedy or claim under this Indenture.

         Section 1.13.    GOVERNING LAW.

         This Indenture and the Securities and coupons shall be governed by and
construed in accordance with the laws of the State of New York, without regard
to principles of conflicts of laws.

         Section 1.14.    LEGAL HOLIDAYS.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities
or coupons other than a provision in the Securities of any series which
specifically states that such provision shall apply in lieu of this Section)
payment of interest or principal (and premium, if any) need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on the
Interest Payment Date or Redemption Date, or at the Stated Maturity, PROVIDED
that no interest shall accrue on the amount so payable for the period from and
after such Interest Payment Date, Redemption Date or Stated Maturity, as the
case may be.

                                 SECURITY FORMS

         Section 2.01.    FORMS GENERALLY.

         The Registered Securities, if any, of each series and the Bearer
Securities, if any, of each series and related coupons shall be in substantially
the form (including temporary or permanent global form) as shall be established
by or pursuant to a Board Resolution of the Company or in one or more indentures
supplemental hereto, in each case with such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Indenture, and may have such letters, numbers or other marks of identification
and such legends or endorsements placed thereon as may be required to comply
with law, or with the rules of any securities exchange or to conform to general
usage, all as may, consistently herewith, be determined by the officers
executing such Securities or coupons, as evidenced by their execution of the
Securities or coupons. If temporary Securities of any series are issued in
global form as permitted by Section 304, the form thereof shall be established
as provided in the preceding sentence. A copy of the Board Resolution of the
Company establishing the forms of Securities or coupons of any series (or any
such temporary global Security) shall be certified by the Secretary or an
Assistant Secretary of the Company and delivered to the Trustee at or prior to
the delivery of the Company Order contemplated by Section 303 for the
authentication and delivery of such Securities (or any such temporary global
Security) or coupons.

         Unless otherwise specified as contemplated by Section 301, Securities
in bearer form shall have interest coupons attached.

         The definitive Securities and coupons, if any, shall be printed,
lithographed or engraved on steel engraved borders or may be produced in any
other manner, all as determined by the officers executing such Securities as
evidenced by their execution of such Securities or coupons.

         Section 2.02.    FORM OF TRUSTEE'S CERTIFICATE OF AUTHENTICATION.

         The Trustee's certificate of authentication shall be in substantially
the following form:

         "This is one of the Securities of the series designated therein
referred to in the within-mentioned Indenture.

                          BANK ONE TRUST COMPANY, NATIONAL ASSOCIATION,

<PAGE>

         Section 2.03.    SECURITIES IN GLOBAL FORM.

         If Securities of a series are issuable in global form, as contemplated
by Section 301, then, notwithstanding clause (10) of Section 301 and the
provisions of Section 302, any such Security shall represent such of the
Outstanding Securities of such series as shall be specified therein and may
provide that it shall represent the aggregate amount of Outstanding Securities
from time to time endorsed thereon and that the aggregate amount of Outstanding
Securities represented thereby may be reduced to reflect exchanges. Any
endorsement of a Security in global form to reflect the amount, or any increase
or decrease in the amount, of Outstanding Securities represented thereby shall
be made by the Trustee in such manner and upon instructions given by such Person
or Persons as shall be specified therein or in the Company Order to be delivered
to the Trustee pursuant to Section 303 or Section 304. Subject to the provisions
of Section 303 and, if applicable, Section 304, the Trustee shall deliver and
redeliver any Security in permanent global form in the manner and upon
instructions given by the Person or Persons specified therein or in the
applicable Company Order. If a Company Order pursuant to Section 303 or 304 has
been, or simultaneously is, delivered, any instructions by the Company with
respect to endorsement or delivery or redelivery of a Security in global form
shall be in writing but need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel.

         The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.

         Notwithstanding the provisions of Sections 201 and 307, unless
otherwise specified as contemplated by Section 301, payment of principal of and
any premium and interest on any Security in permanent global form shall be made
to the Person or Persons specified therein.

         Section 2.04.    FORM OF LEGEND FOR BOOK-ENTRY SECURITIES.

         Any Book-Entry Security authenticated and delivered hereunder shall
bear a legend in substantially the following form:

         "This Security is a Book-Entry Security within the meaning of the
Indenture hereinafter referred to and is registered in the name of a Depository
or a nominee of a Depository. This Security is exchangeable for Securities
registered in the name of a Person other than the Depository or its nominee only
in the limited circumstances described in the Indenture, and no transfer of this
Security (other than a transfer of this Security as a whole by the Depository to
a nominee of the Depository or by a nominee of the Depository to the Depository
or another nominee of the Depository) may be registered except in such limited
circumstances."

         and except for any Securities which, pursuant to Section 303, are
         deemed never to have been authenticated and delivered hereunder);

         occur, if other than in the manner provided in Section 305;

         of the series shall be payable, if other than the Person in whose name

the Securities may be manual or facsimile. Coupons shall bear the facsimile
signature of the Treasurer or any Assistant Treasurer of the Company.

                                     18

<PAGE>

         Securities and coupons bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities or coupons.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series, together with
any coupons appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities; PROVIDED, HOWEVER, that,
unless otherwise provided with respect to such series, in connection with its
original issuance, during the "restricted period" (as defined in Section
1.163-5(c)(2)(i)(D)(7) of the United States Treasury Regulations) (the
"restricted period") no Bearer Security shall be mailed or otherwise delivered
to any location in the United States; and PROVIDED, FURTHER, that, unless
otherwise provided with respect to such series, a Bearer Security may be
delivered in connection with its original issuance only if the Person entitled
to receive such Bearer Security shall have furnished a certificate in the form
set forth in Exhibit A to this Indenture, dated no earlier than the
Certification Date. If any Security shall be represented by a permanent global
Bearer Security, then, for purposes of this Section and Section 304, the
notation of a beneficial owner's interest therein upon original issuance of such
Security or upon exchange of a portion of a temporary global Security shall be
deemed to be delivery in connection with its original issuance during the
restricted period of such beneficial owner's interest in such permanent global
Security. Except as permitted by Section 306, the Trustee shall not authenticate
and deliver any Bearer Security unless all appurtenant coupons for interest then
matured have been detached and cancelled.

         In authenticating Securities, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating:

                  (a) that the forms of such Securities and coupons established
         by or pursuant to a Board Resolution of the Company as contemplated by
         Section 201 have been established in conformity with the provisions of
         this Indenture;

                  (b) if the terms of such Securities and any coupons have been
         established by or pursuant to a Board Resolution of the Company as
         permitted by Section 301, that such terms have been established in
         conformity with the provisions of this Indenture; and

                  (c) that such Securities, together with any coupons
         appertaining thereto, when authenticated and delivered by the Trustee
         and issued by the Company in the manner and subject to any conditions
         specified in such Opinion of Counsel, will constitute valid and legally
         binding obligations of the Company enforceable in accordance with their
         terms, subject to bankruptcy, insolvency, fraudulent transfer,
         reorganization and other laws of general applicability relating to or
         affecting creditors' rights and to general equity principles.

Such Opinion of Counsel shall also cover such other matters as the Trustee may
reasonably request.

                                     19

<PAGE>

         The Trustee shall not be required to authenticate such Securities the
forms or terms of which have been established by or pursuant to a Board
Resolution of the Company if the issue of such Securities pursuant to this
Indenture will affect the Trustee's own rights, duties or immunities under the
Securities and this Indenture or otherwise in a manner which is not reasonably
acceptable to the Trustee.

         Notwithstanding the provisions of Section 301 and of the two preceding
paragraphs, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraphs at or prior to the time
of authentication of each Security of such series if such documents are
delivered at or prior to the authentication upon issuance of the first Security
of such series to be issued.

         After the original issuance of the first Security of such series to be
issued, any separate request by the Company that the Trustee authenticate
Securities of such series for original issuance will be deemed to be a
certification by the Company (which, subject to Section 601, the Trustee shall
be fully protected in relying on) that it is in compliance with all conditions
precedent provided for in this Indenture relating to the authentication and
delivery of such Securities.

         Each Registered Security shall be dated the date of its authentication;
and each Bearer Security shall be dated as of the date of original issuance of
the first Security of such series to be issued.

         No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security, or the Security to which such coupon appertains, a certificate of
authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Security shall be
conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered hereunder. Notwithstanding the foregoing, if any
Security shall have been authenticated and delivered hereunder but never issued
and sold by the Company, and the Company shall deliver such Security to the
Trustee for cancellation as provided in Section 309 together with a written
statement (which need not comply with Section 102 and need not be accompanied by
an Opinion of Counsel) stating that such Security has never been issued and sold
by the Company, for all purposes of this Indenture such Security shall be deemed
never to have been authenticated and delivered hereunder and shall never be
entitled to the benefits of this Indenture.

         Section 3.04.    TEMPORARY SECURITIES.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten or
otherwise produced, in any authorized denomination, substantially of the tenor
of the definitive Securities in lieu of which they are issued, in registered
form or, if authorized, in bearer form with one or more coupons or without
coupons, and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities. In

                                     20

<PAGE>

the case of any series issuable as Bearer Securities, such temporary
Securities may be in global form. A temporary Bearer Security shall be
delivered only in compliance with the conditions set forth in Section 303.

         Except in the case of temporary Securities in global form (which shall
be exchanged in accordance with the provisions of the following paragraphs), if
temporary Securities of any series are issued, the Company will cause definitive
Securities of that series to be prepared without unreasonable delay. After the
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company maintained pursuant to Section 1002 in a Place of Payment for such
series for the purpose of exchanges of Securities of such series without charge
to the Holder. Upon surrender for cancellation of any one or more temporary
Securities of any series (accompanied by any unmatured coupons appertaining
thereto) the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like aggregate principal amount of definitive
Securities of the same series and of like tenor of authorized denominations;
PROVIDED, HOWEVER, that no definitive Bearer Security shall be issued in
exchange for a temporary Registered Security.

         If temporary Securities of any series are issued in global form, any
such temporary global Security shall, unless otherwise provided therein, be
delivered to the London office of a depositary or common depositary (the "Common
Depositary"), for the benefit of Euro-clear and CEDEL S.A., for credit to the
respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).

         Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security of a series (the "Exchange Date"), the Company shall deliver to the
Trustee definitive Securities of that series in aggregate principal amount equal
to the principal amount of such temporary global Security, executed by the
Company. On or after the Exchange Date such temporary global Security shall be
surrendered by the Common Depositary to the Trustee, as the Company's agent for
such purpose, to be exchanged, in whole or from time to time in part, for
definitive Securities of that series without charge and the Trustee shall
authenticate and deliver, in exchange for each portion of such temporary global
Security, a like aggregate principal amount of definitive Securities of the same
series of authorized denominations and of like tenor as the portion of such
temporary global Security to be exchanged; provided, however, that, unless
otherwise specified in such temporary global Security, upon such presentation by
the Common Depositary, such temporary global Security is accompanied by a
certificate dated the Exchange Date or a subsequent date and signed by
Euro-clear as to the portion of such temporary global Security held for its
account then to be exchanged and a certificate dated the Exchange Date or a
subsequent date and signed by CEDEL S.A. as to the portion of such temporary
global Security held for its account then to be exchanged, each in the form set
forth in Exhibit B to this Indenture. The definitive Securities to be delivered
in exchange for any such temporary global Security shall be in bearer form,
registered form, permanent global bearer form or permanent global registered
form, or any combination thereof, as specified as contemplated by Section 301,
and if any combination thereof is so specified, as requested by the beneficial
owner thereof; PROVIDED, HOWEVER, that no

                                     21

<PAGE>

definitive Bearer Security or permanent global Security shall be delivered in
exchange for a temporary Bearer Security except in compliance with the
conditions set forth in Section 303.

         Unless otherwise specified in the temporary global Security, the
interest of a beneficial owner of Securities of a series in a temporary global
Security shall be exchanged on the Exchange Date for definitive Securities (and
where the form of the definitive Securities is not specified by the Holder for
an interest in a permanent global Security) of the same series and of like tenor
unless, on or prior to the Exchange Date, such beneficial owner has not
delivered to Euro-clear or CEDEL S.A., as the case may be, a certificate in the
form set forth in Exhibit A to this Indenture dated no earlier than the
Certification Date, copies of which certificate shall be available from the
offices of Euro-clear and CEDEL S.A., the Trustee, any Authenticating Agent
appointed for such series of Securities and each Paying Agent and after the
Exchange Date, the interest of a beneficial owner of Securities of a series in a
temporary global Security shall be exchanged for definitive Securities (and
where the form of the definitive Securities is not specified by the Holder for
an interest in a permanent global Security) of the same series and of like tenor
following such beneficial owner's delivery to Euro-clear or CEDEL S.A., as the
case may be, of a certificate in the form set forth in Exhibit A to this
Indenture dated no earlier than the Certification Date. Unless otherwise
specified in such temporary global Security, any exchange shall be made free of
charge to the beneficial owners of such temporary global Security, except that a
Person receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like in the event that such Person does not take delivery
of such definitive Securities in person at the offices of Euro-clear or CEDEL
S.A. Definitive Securities in bearer form to be delivered in exchange for any
portion of a temporary global Security shall be delivered only outside the
United States.

         Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary global
Security on an Interest Payment Date for Securities of such series shall be
payable to Euro-clear and CEDEL S.A. on such Interest Payment Date upon delivery
by Euro-clear and CEDEL S.A. to the Trustee of a certificate or certificates in
the form set forth in Exhibit B to this Indenture, for credit without further
interest on or after such Interest Payment Date to the respective accounts of
the Persons who are the beneficial owners of such temporary global Security on
such Interest Payment Date and who have each delivered to Euro-clear or CEDEL
S.A., as the case may be, a certificate in the form set forth in Exhibit A to
this Indenture. Any interest so received by Euro-clear and CEDEL S.A. and not
paid as herein provided shall be returned to the Trustee immediately prior to
the expiration of two years after such Interest Payment Date in order to be
repaid to the Company in accordance with Section 1003.

         Section 3.05.    REGISTRATION, REGISTRATION OF TRANSFER AND
EXCHANGE.

         The Company shall cause to be kept at an office or agency to be
maintained by the Company in accordance with Section 1002 a register (being the
combined register of the Security Registrar and all transfer agents designated
pursuant to Section 1002 for the purpose of registration of transfer of
Securities and sometimes collectively referred to as the "Security Register") in
which, subject to such reasonable regulations as it may prescribe, the Company

                                     22

<PAGE>

shall provide for the registration of each series of Registered Securities and
the registration of transfers of such Registered Securities. The Company shall
serve initially as "Security Registrar" for the purpose of registering
Registered Securities and transfers of Registered Securities as herein provided.

         Upon surrender for registration of transfer of any Registered Security
of any series at the office or agency of the Company maintained pursuant to
Section 1002 for such purpose in a Place of Payment for such series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Registered Securities
of the same series of any authorized denominations and of a like aggregate
principal amount and tenor.

         At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount and tenor, upon surrender
of the Securities to be exchanged at any such office or agency. Whenever any
Securities are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive. Unless otherwise provided with respect to
any series of Securities, Bearer Securities may not be issued in exchange for
Registered Securities.

         At the option of the Holder, Bearer Securities of any series may be
exchanged for Registered Securities of the same series of any authorized
denominations and of a like aggregate principal amount and tenor, upon surrender
of the Bearer Securities to be exchanged at any such office or agency, with all
unmatured coupons and all matured coupons in default thereto appertaining. If
the Holder of a Bearer Security is unable to produce any such unmatured coupon
or coupons or matured coupon or coupons in default, such exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Company in an amount equal to the face amount of such missing coupon or
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Security shall surrender to any Paying Agent any
such missing coupon in respect of which such a payment shall have been made,
such Holder shall be entitled to receive the amount of such payment; provided,
however, that, except as otherwise provided in Section 1002, interest
represented by coupons shall be payable only upon presentation and surrender of
those coupons at an office or agency located outside the United States.
Notwithstanding the foregoing, in case a Bearer Security of any series is
surrendered at any such office or agency in exchange for a Registered Security
of the same series and like tenor after the close of business at such office or
agency on (i) any Regular Record Date and before the opening of business at such
office or agency on the relevant Interest Payment Date, or (ii) any Special
Record Date and before the opening of business at such office or agency on the
related proposed date for payment of Defaulted Interest, such Bearer Security
shall be surrendered without the coupon relating to such Interest Payment Date
or proposed date for payment, as the case may be, and interest or Defaulted
Interest, as the case may be, will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security but will be payable only to
the Holder of such coupon when due in accordance with the provisions of this
Indenture.

                                     23

<PAGE>

         Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive.

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent global Security shall be exchangeable
only as provided in this paragraph. If the beneficial owners of interests in a
permanent global Security are entitled to exchange such interests for Securities
of such series and of like tenor and principal amount of another authorized form
and denomination, as specified as contemplated by Section 301, then without
unnecessary delay but in any event not later than the earliest date on which
such interests may be so exchanged, the Company shall deliver to the Trustee
definitive Securities of that series in an aggregate principal amount equal to
the principal amount of such permanent global Security, executed by the Company.
On or after the earliest date on which such interests may be so exchanged, such
permanent global Security shall be surrendered from time to time in accordance
with instructions given to the Trustee and the Common Depositary (which
instructions shall be in writing but need not comply with Section 102 or be
accompanied by an Opinion of Counsel) by the Common Depositary or such other
depositary or Common Depositary as shall be specified in the Company Order with
respect thereto to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or in part, for definitive Securities of the same series
without charge and the Trustee shall authenticate and deliver, in exchange for
each portion of such permanent global Security, a like aggregate principal
amount of definitive Securities of the same series of authorized denominations
and of like tenor as the portion of such permanent global Security to be
exchanged which, unless the Securities of the series are not issuable both as
Bearer Securities and as Registered Securities, as specified as contemplated by
Section 301, shall be in the form of Bearer Securities or Registered Securities,
or any combination thereof, as shall be specified by the beneficial owner
thereof; PROVIDED, HOWEVER, that no such exchanges may occur during a period
beginning at the opening of business 15 days before any selection of Securities
of that series is to be redeemed and ending on the relevant Redemption Date; and
PROVIDED, FURTHER, that no Bearer Security delivered in exchange for a portion
of a permanent global Security shall be mailed or otherwise delivered to any
location in the United States. Promptly following any such exchange in part,
such permanent global Security shall be returned by the Trustee to the Common
Depositary or such other depositary or Common Depositary referred to above in
accordance with the instructions of the Company referred to above. If a
Registered Security is issued in exchange for any portion of a permanent global
Security after the close of business at the office or agency where such exchange
occurs on (i) any Regular Record Date and before the opening of business at such
office or agency on the relevant Interest Payment Date, or (ii) any Special
Record Date and before the opening of business at such office or agency on the
related proposed date for payment of Defaulted Interest, interest or Defaulted
Interest, as the case may be, will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of such Registered
Security, but will be payable on such Interest Payment Date or proposed date for
payment, as the case may be, only to the Person to whom interest in respect of
such portion of such permanent global Security is payable in accordance with
provisions of this Indenture.

         All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

                                     24
<PAGE>

         Every Registered Security presented or surrendered for registration of
transfer or exchange shall (if so required by the Company or the Trustee or any
transfer agent) be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar or any
transfer agent duly executed, by the Holder thereof or his attorney duly
authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

         The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before any selection of Securities of that series to be
redeemed and ending at the close of business on (A) if Securities of the series
are issuable only as Registered Securities, the day of the mailing of the
relevant notice of redemption and (B) if Securities of the series are issuable
as Bearer Securities, the day of the first publication of the relevant notice of
redemption, or if Securities of the series are also issuable as Registered
Securities and there is no publication, the mailing of the relevant notice of
redemption, or (ii) to register the transfer of or exchange any Registered
Security so selected for redemption, in whole or in part, except the unredeemed
portion of any Registered Security being redeemed in part, or (iii) to exchange
any Bearer Security so selected for redemption except that such a Bearer
Security may be exchanged for a Registered Security of that series and like
tenor, PROVIDED that such Registered Security shall be simultaneously
surrendered for redemption.

         Notwithstanding the foregoing and except as otherwise specified or
contemplated by Section 301, any Book-Entry Security shall be exchangeable
pursuant to this Section 305 or Sections 304, 906 and 1107 for Securities
registered in the name of, and a transfer of a Book-Entry Security of any series
may be registered to, any Person other than the Depository for such Security or
its nominee only if (i) such Depository notifies the Company that it is
unwilling or unable to continue as Depository for such Book-Entry Security or if
at any time such Depository ceases to be a clearing agency registered under the
Securities Exchange Act of 1934, as amended, (ii) the Company executes and
delivers to the Trustee a Company Order that such Book-Entry Security shall be
so exchangeable and the transfer thereof so registrable or (iii) there shall
have occurred and be continuing an Event of Default, with respect to the
Securities of such series. Upon the occurrence in respect of any Book-Entry
Security of any series of any one or more of the conditions specified in clause
(i), (ii) or (iii) of the preceding sentence or such other conditions as may be
specified, such Book-Entry Security may be exchanged for Securities registered
in the names of, and the transfer of such Book-Entry Security may be registered
to, such Persons (including Persons other than the Depository with respect to
such series and its nominees) as such Depository shall direct. Notwithstanding
any other provision of this Indenture, any Security authenticated and delivered
upon registration of transfer of, or in exchange for, or in lieu of, any
Book-Entry Security shall also be a Book-Entry Security and shall bear the
legend specified in Section 204 except for any Security authenticated and
delivered in exchange for, or upon registration of transfer of, a Book-Entry
Security pursuant to the preceding sentence.

         Section 3.06.    MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES
AND COUPONS.

         If any mutilated Security or a Security with a mutilated coupon
appertaining thereto is surrendered to the Trustee, the Company shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new
Security of the same series and of like tenor and principal amount and bearing a
number not contemporaneously outstanding, with coupons corresponding to the
coupons, if any, appertaining to the surrendered Security.

         If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security or
coupon and (ii) such security or indemnity as may be required by them to save
each of them and any agent of either of them harmless, then, in the absence of
notice to the Company or the Trustee that such Security or coupon has been
acquired by a bona fide purchaser, the Company shall execute and the Trustee
shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security or in exchange for the Security to which a destroyed, lost or stolen
coupon appertains (with all appurtenant coupons not destroyed, lost or stolen),
a new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding, with coupons corresponding
to the coupons, if any, appertaining to such destroyed, lost or stolen Security
or to the Security to which such destroyed, lost or stolen coupon appertains.

         In case any such mutilated, destroyed, lost or stolen Security or
coupon has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Security, pay such Security or coupon;
PROVIDED, HOWEVER, that the principal of and any premium and interest on Bearer
Securities shall, except as otherwise provided in Section 1002, be payable only
at an office or agency located outside the United States.

         Upon the issuance of any new Security under this Section, the Company
may require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

         Every new Security of any series with its coupons, if any, issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security or in
exchange for a Security to which a destroyed, lost or stolen coupon appertains,
shall constitute an original additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Security and its coupons, if any,
or the destroyed, lost or stolen coupon shall be at any time enforceable by
anyone, and any such new Security and coupons, if any, shall be entitled to all
the benefits of this Indenture equally and proportionately with any and all
other Securities of that series and their coupons, if any, duly issued
hereunder.

         The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities or coupons.

         Section 3.07.    PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

         Unless otherwise provided as contemplated by Section 301 with respect
to any series of Securities, interest on any Registered Security which is
payable, and is punctually paid or duly

                                     26

<PAGE>

provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest. Unless otherwise so provided, at the option of the Company, payment
of interest on any Registered Security may be made by check mailed on or
before the due date to the address of the Person entitled thereto as such
address shall appear in the Security Register.

         Any interest on any Registered Security of any series which is payable,
but is not punctually paid or duly provided for, on any Interest Payment Date
(herein called "Defaulted Interest") shall forthwith cease to be payable to the
Holder on the relevant Regular Record Date by virtue of having been such Holder,
and such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Registered Securities of
         such series (or their respective Predecessor Securities) are registered
         at the close of business on a Special Record Date for the payment of
         such Defaulted Interest, which shall be fixed in the following manner.
         The Company shall notify the Trustee in writing of the amount of
         Defaulted Interest proposed to be paid on each Registered Security of
         such series and the date of the proposed payment, and at the same time
         the Company shall deposit with the Trustee an amount of money equal to
         the aggregate amount proposed to be paid in respect of such Defaulted
         Interest or shall make arrangements satisfactory to the Trustee for
         such deposit prior to the date of the proposed payment, such money when
         deposited to be held in trust for the benefit of the Persons entitled
         to such Defaulted Interest as in this Clause provided. Thereupon the
         Trustee shall fix a Special Record Date for the payment of such
         Defaulted Interest which shall be not more than 15 days and not less
         than 10 days prior to the date of the proposed payment and not less
         than 10 days after the receipt by the Trustee of the notice of the
         proposed payment. The Trustee shall promptly notify the Company of such
         Special Record Date and, in the name and at the expense of the Company,
         shall cause notice of the proposed payment of such Defaulted Interest
         and the Special Record Date therefor to be mailed, first-class postage
         prepaid, to each Holder of Registered Securities of such series at the
         address of such Holder as it appears in the Security Register, not less
         than 10 days prior to such Special Record Date. The Trustee may, in its
         discretion, in the name and at the expense of the Company, cause a
         similar notice to be published at least once in an Authorized
         Newspaper, PROVIDED such publication shall not be a condition precedent
         to the establishment of such Special Record Date. Notice of the
         proposed payment of such Defaulted Interest and the Special Record Date
         therefor having been so mailed, such Defaulted Interest shall be paid
         to the Persons in whose names the Registered Securities of such series
         (or their respective Predecessor Securities) are registered at the
         close of business on such Special Record Date and shall no longer be
         payable pursuant to the following clause (2).

                  (2) The Company may make payment of any Defaulted Interest on
         the Registered Securities of any series in any other lawful manner not
         inconsistent with the requirements of any securities exchange on which
         such Securities may be then listed, and upon such notice as may be
         required by such exchange, if, after notice given by the

                                     27

<PAGE>

         Company to the Trustee of the proposed payment pursuant to this Clause,
         such manner of payment shall be deemed practicable by the Trustee.

         Subject to the foregoing provisions of this Section and Section 305,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

         Section 3.08.    PERSONS DEEMED OWNERS.

         Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Sections 305 and 307) any
interest on such Registered Security and for all other purposes whatsoever,
whether or not such Security be overdue, and none of the Company, the Trustee
nor any agent of the Company or the Trustee shall be affected by notice to the
contrary.

         Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. The Company, the Trustee and any agent of the Company or the
Trustee may treat the bearer of any Bearer Security and the bearer of any coupon
as the owner of such Bearer Security or coupon for the purpose of receiving
payment thereof or on account thereof and for all other purposes whatsoever,
whether or not such Security or coupon be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

         Notwithstanding the foregoing, with respect to any Book-Entry Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by a Depository or impair, as between a
Depository and holders of beneficial interests in any Book-Entry Security, the
operation of customary practices governing the exercise of the rights of the
Depository (or its nominee) as Holder of such Book-Entry Security.

         Section 3.09.    CANCELLATION.

         All Securities and coupons surrendered for payment, redemption,
registration of transfer or exchange or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee. All Registered Securities and matured coupons so delivered shall
be promptly cancelled by the Trustee. All Bearer Securities and unmatured
coupons so delivered shall be held by the Trustee and, upon instruction by a
Company Order, shall be cancelled or held for reissuance. Bearer Securities and
unmatured coupons held for reissuance may be reissued only in replacement of
mutilated, lost, stolen or destroyed Bearer Securities of the same series and
like tenor or the related coupons pursuant to Section 306. All Bearer Securities
and unmatured coupons held by the Trustee pending such cancellation or
reissuance shall be deemed to be delivered for all purposes of this Indenture
and the Securities. The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company may have

                                     28

<PAGE>

acquired in any manner whatsoever, and may deliver to the Trustee (or to any
other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly cancelled by the Trustee.
No Securities shall be authenticated in lieu of or in exchange for any
Securities cancelled as provided in this Section, except as expressly
permitted by this Indenture. All cancelled Securities and coupons held by the
Trustee shall be disposed of in accordance with its customary practice.

         Section 3.10.    COMPUTATION OF INTEREST.

         Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE

         Section 4.01.     SATISFACTION AND DISCHARGE OF INDENTURE.

         This Indenture shall upon Company Request cease to be of further effect
with respect to Securities of a Series (except as to any surviving rights of
registration of transfer or exchange of Securities herein expressly provided
for, and any right to receive additional amounts, as provided in Section 1004),
and the Trustee, at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture with respect to
Securities of a Series, when

                  (1) either

                  (A) all Securities of such Series theretofore authenticated
         and delivered and all coupons, if any, appertaining thereto (other than
         (i) coupons appertaining to Bearer Securities surrendered for exchange
         for Registered Securities and maturing after such exchange, whose
         surrender is not required or has been waived as provided in Section
         305, (ii) Securities and coupons which have been destroyed, lost or
         stolen and which have been replaced or paid as provided in Section 306,
         (iii) coupons appertaining to Securities called for redemption and
         maturing after the relevant Redemption Date, whose surrender has been
         waived as provided in Section 1106, and (iv) Securities and coupons for
         whose payment money has theretofore been deposited in trust or
         segregated and held in trust by the Company and thereafter repaid to
         the Company or discharged from such trust, as provided in Section 1003)
         have been delivered to the Trustee for cancellation; or

                  (B) with respect to all such Securities and, in the case of
         (i) or (ii) below, any coupons appertaining thereto not theretofore
         delivered to the Trustee for cancellation

                           (i)   have become due and payable, or

                           (ii)  will become due and payable at their Stated
                  Maturity within one year, or

                                     29

<PAGE>

                           (iii) are to be called for redemption within one year
                  under arrangements satisfactory to the Trustee for the giving
                  of notice of redemption by the Trustee in the name, and at the
                  expense, of the Company;

         and the Company, in the case of (i), (ii) or (iii) above, has deposited
or caused to be deposited with the Trustee as trust funds in trust for the
purpose an amount sufficient to pay and discharge the entire indebtedness on
such Securities and coupons not theretofore delivered to the Trustee for
cancellation, for principal (and premium, if any) and any interest to the date
of such deposit (in the case of Securities which have become due and payable) or
to the Stated Maturity or Redemption Date, as the case may be;

                  (2) the Company has paid or caused to be paid all other sums
         payable hereunder by the Company; and

                  (3) the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent herein provided for relating to the satisfaction and
         discharge of this Indenture have been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to clause (1)(B) of this Section,
the obligations of the Company under Sections 306, 610(e) and 701 and the
obligations of the Trustee under Section 402 and the last paragraph of Section
1003 shall survive.

         Section 4.02.    APPLICATION OF TRUST MONEY.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities, the
coupons and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal and any
premium and interest for whose payment such money has been deposited.

         Section 5.01.    EVENTS OF DEFAULT.

         "Event of Default," wherever used herein with respect to Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order, rule or
regulation of any administrative or governmental body), unless it is either

                  (5) default in the performance, or breach, of any covenant or
         warranty of the Company in this Indenture (other than a covenant or
         warranty a default in whose performance or whose breach is elsewhere in
         this Section specifically dealt with or which has expressly been
         included in this Indenture solely for the benefit of series of
         Securities other than that series), and continuance of such default or
         breach for a period of 90 days after there has been given, by
         registered or certified mail, to the Company by the Trustee or to the
         Company and the Trustee by the Holders of at least 25% in principal
         amount of the Outstanding Securities of that series a written notice
         specifying such default or breach and requiring it to be remedied and
         stating that such notice is a "Notice of Default" hereunder; or

                  (6) the entry by a court having jurisdiction in the premises
         of (A) a decree or order for relief in respect of the Company in an

         decree or order adjudging the Company as bankrupt or insolvent, or
         approving as properly filed a petition seeking reorganization,
         arrangement, adjustment or composition of or in respect of the Company
         under any applicable Federal or state law, or appointing a custodian,
         receiver, liquidator, assignee, trustee, sequestrator or other similar
         official of the Company or of any substantial part of the property of
         the Company, or ordering the winding up or liquidation of its affairs,
         and the continuance of any such decree or order for relief or any such
         other decree or order unstayed and in effect for a period of 90
         consecutive days; or

                  (7) the commencement by the Company of a voluntary case or

         it to the entry of a decree or order for relief in respect of the
         Company in an involuntary case or proceeding under any applicable
         Federal or state bankruptcy, insolvency, reorganization or other
         similar law or the commencement of any bankruptcy or insolvency case or
         proceeding against the Company, or the filing by the Company of a
         petition or answer or consent seeking reorganization or relief under

         the filing of such petition or to the appointment of or taking
         possession by a custodian, receiver, liquidator, assignee, trustee,
         sequestrator or similar official of the Company or of any substantial
         part of the property of the Company, or the making by the Company of an
         assignment for the benefit

                                     31

<PAGE>
         of creditors, or the admission by the Company in writing of its
         inability to pay its debts generally as they become due, or the
         taking of corporate action by the Company in furtherance of any
         such action; or

                  (8) any other Event of Default provided with respect to
         Securities of that series.

         Section 5.02.    ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount (or, if any of the
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified in the terms
thereof) of all of the Securities of that series to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders), and upon any such declaration such principal amount (or specified
amount) shall become immediately due and payable.

         At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if

                  (1)      the Company has paid or deposited with the Trustee a
         sum sufficient to pay

                           (A) all overdue interest on, and any additional
                  amounts payable as set forth in Section 1004 on, all
                  Securities of that series and any coupons appertaining
                  thereto,

                           (B) the principal of (and premium, if any, on) any
                  Securities of that series which have become due otherwise than
                  by such declaration of acceleration and any interest thereon
                  at the rate or rates prescribed therefor in such Securities,

                           (C) to the extent that payment of such interest is
                  lawful, interest upon overdue interest, and any additional
                  amounts payable as set forth in Section 1004 on, at the rate
                  or rates prescribed therefor in such Securities, and

                           (D) all sums paid or advanced by the Trustee
                  hereunder and the reasonable compensation, expenses,
                  disbursements and advances of the Trustee, its agents and
                  counsel;

         and

                  (2) all Events of Default with respect to Securities of that
         series, other than the non-payment of the principal of Securities of
         that series which have become due solely

                                     32

<PAGE>

         by such declaration of acceleration, have been cured or waived as
         provided in Section 513.

         No such rescission shall affect any subsequent default or impair any
right consequent thereon.

         Section 5.03.    COLLECTION OF INDEBTEDNESS AND SUITS FOR
                          ENFORCEMENT BY TRUSTEE.

         The Company covenants that if

                  (1) default is made in the payment of any interest on any
         Security when such interest becomes due and payable and such default
         continues for a period of 30 days, or

                  (2) default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities and coupons, the whole amount then due and payable on
such Securities and coupons for principal and any premium and interest and, to
the extent that payment of such interest shall be legally enforceable, interest
on any overdue principal and premium and on any overdue interest, at the rate or
rates prescribed therefor in such Securities (or, in the case of Original Issue
Discount Securities, the Securities' yield to maturity) and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever
situated.

         If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series
and any related coupons by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights, whether for
the specific enforcement of any covenant or agreement in this Indenture or in
aid of the exercise of any power granted herein, or to enforce any other proper
remedy.

         Section 5.04.    TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), or the property or the creditors of the
Company, the Trustee shall be entitled and empowered, by intervention in such
proceeding or otherwise, to take any and all actions authorized under the Trust
Indenture Act in order to have claims of the Holders and the Trustee allowed in
any such proceeding. In particular, the Trustee shall be authorized to collect
and receive any moneys or other property payable or deliverable on any such
claims and to distribute

                                     33

<PAGE>

the same; and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar official in any such judicial proceeding is
hereby authorized by each Holder to make such payments to the Trustee and, in
the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee under Section
607.

         No provision of this Indenture shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding; PROVIDED,
HOWEVER, that the Trustee may, on behalf of Holders, vote for the election of a
trustee of bankruptcy or similar official and be a member of a creditors' or
other similar committee.

         Section 5.05.    TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF
                          SECURITIES OR COUPONS.

         All rights of action and claims under this Indenture or the Securities
or coupons may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or coupons or the production thereof in any proceeding
relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of
judgment shall, after provision for the payment of reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Holders of the Securities and coupons in respect
of which such judgment has been recovered.

         Section 5.06.    APPLICATION OF MONEY COLLECTED.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal or any premium
or interest, upon presentation of the Securities or coupons, or both as the case
may be, and the notation thereon of the payment if only partially paid and upon
surrender thereof if fully paid:

                  FIRST: To the payment of all amounts due the Trustee under
         Section 607; and

                  SECOND: To the payment of the amounts then due and unpaid for
         principal of and any premium and interest on the Securities and coupons
         in respect of which or for the benefit of which such money has been
         collected, ratably, without preference or priority of any kind,
         according to the amounts due and payable on such Securities and coupons
         for principal and any premium and interest, respectively.

                  THIRD:  The balance, if any, to the Person or Persons entitled
         thereto.

         In any case in which Securities are Outstanding that are denominated in
more than one currency and the Trustee is directed to make ratable payments
under this Section to Holders of such Securities, unless otherwise provided with
respect to any series of Securities, the Trustee shall calculate the amount of
such payments as follows: (i) as of the day the Trustee collects

                                     34
<PAGE>

an amount under this Article, the Trustee shall, as to each Holder of a
Security to whom an amount is due and payable under this Section that is
denominated in a foreign currency, determine that amount in Dollars that
would be obtained for the amount owing such Holder, using the rate of
exchange at which in accordance with normal banking procedures the Trustee
could purchase in The City of New York Dollars with such amount owing; (ii)
calculate the sum of all Dollar amounts determined under (i) and add thereto
any amounts due and payable in Dollars; and (iii) using the individual
amounts determined in (i) or any individual amounts due and payable in
Dollars, as the case may be, as a numerator, and the sum calculated in (ii)
as a denominator, calculate as to each Holder of a Security to whom an amount
is owed under this Section the fraction of the amount collected under this
Article payable to such Holder. Any expenses incurred by the Trustee in
actually converting amounts owing Holders of Securities denominated in a
currency other than that in which any amount is collected under this Article
shall be likewise (in accordance with this paragraph) borne ratably by all
Holders of Securities to whom amounts are payable under this Section.

         To the fullest extent allowed under applicable law, if for the purpose
of obtaining judgment against the Company in any court it is necessary to
convert the sum due in respect of the principal of, or premium, if any, or
interest on, the Securities of any series (the "Required Currency") into a
currency in which a judgment will be rendered (the "Judgment Currency"), the
rate of exchange used shall be the rate at which in accordance with normal
banking procedures the Trustee could purchase in The City of New York the
Required Currency with the Judgment Currency on the Business Day in the City of
New York next preceding that on which final judgment is given. Neither the
Company nor the Trustee shall be liable for any shortfall nor shall it benefit
from any windfall in payments to Holders of Securities under this Section caused
by a change in exchange rates between the time the amount of a judgment against
the Company is calculated as above and the time the Trustee converts the
Judgment Currency into the Required Currency to make payments under this Section
to Holders of Securities, but payment of such judgment shall discharge all
amounts owed by the Company on the claim or claims underlying such judgment.

         Section 5.07.    LIMITATION ON SUITS.

         No Holder of any Security of any series or any related coupons shall
have any right to institute any proceeding, judicial or otherwise, with respect
to this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless:

                  (1) such Holder has previously given written notice to the
         Trustee of a continuing Event of Default with respect to the Securities
         of that series;

                  (2) the Holders of not less than 25% in principal amount of
         the Outstanding Securities of that series shall have made written
         request to the Trustee to institute proceedings in respect of such
         Event of Default in its own name as Trustee hereunder;

                  (3) such Holder or Holders have offered to the Trustee
         reasonable indemnity against the costs, expenses and liabilities to be
         incurred in compliance with such request;

<PAGE>

                  (4) the Trustee for 60 days after its receipt of such notice,
         request and offer of indemnity has failed to institute any such
         proceeding; and

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of the Outstanding Securities of that
         series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other of
such Holders, or to obtain or to seek to obtain priority or preference over any
other of such Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all such
Holders.

         Section 5.08.    UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE
                          PRINCIPAL, PREMIUM AND INTEREST.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security or coupon shall have the right, which is absolute and
unconditional, to receive payment of the principal of and any premium and
(subject to Sections 305 and 307) any interest on such Security or payment of
such coupon on the Stated Maturity or Maturities expressed in such Security or
coupon (or, in the case of redemption, on the Redemption Date) and to institute
suit for the enforcement of any such payment, and such rights shall not be
impaired without the consent of such Holder.

         Section 5.09.    RESTORATION OF RIGHTS AND REMEDIES.

         If the Trustee or any Holder of a Security or coupon has instituted any
proceeding to enforce any right or remedy under this Indenture and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case, subject to any determination in such proceeding, the Company, the Trustee
and the Holders of Securities and coupons shall be restored severally and
respectively to their former positions hereunder and thereafter all rights and
remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

         Section 5.10.    RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities or coupons in the last
paragraph of Section 306, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders of Securities or coupons is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

         Section 5.11.    DELAY OR OMISSION NOT WAIVER.

         No delay or omission of the Trustee or of any Holder of any Security or
coupon to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Trustee or to the Holders of Securities or coupons may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders of Securities or coupons, as the case may be.

         Section 5.12.    CONTROL BY HOLDERS OF SECURITIES.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee, with respect to the
Securities of such series, provided that

                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture;

                  (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction; and

                  (3) the Trustee shall not be obligated to take any action
         unduly prejudicial to Holders not joining in such direction or
         involving the Trustee in personal liability.

         Section 5.13.    WAIVER OF PAST DEFAULTS.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series may on behalf of the Holders of all the Securities of
such series waive any past default hereunder with respect to the Securities of
such series and its consequences, except a default

                  (1) in the payment of the principal of or any premium or
         interest on any Security of such series, or

                  (2) in respect of a covenant or provision hereof which under
         Article Nine cannot be modified or amended without the consent of the
         Holder of each Outstanding Security of such series affected.

         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

         Section 5.14.    UNDERTAKING FOR COSTS.

         In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess costs against
any such party litigant, in the manner and to the extent provided in the Trust

                                     37

<PAGE>

Indenture Act; PROVIDED that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to make
such an assessment in any suit instituted by the Company.

         Section 5.15.    WAIVER OF STAY OR EXTENSION LAWS.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
to take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                   ARTICLE SIX

                                   THE TRUSTEE

         Section 6.01.    CERTAIN DUTIES AND RESPONSIBILITIES.

         The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

         Section 6.02.    NOTICE OF DEFAULTS.

         If a default occurs hereunder with respect to Securities of any series,
the Trustee shall give the Holders of Securities of such series notice of such
default as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any default of the character specified in Section
501(5) with respect to Securities of such series, no such notice to Holders
shall be given until at least 30 days after the occurrence thereof. For the
purpose of this Section, the term "default" means any event which is, or after
notice or lapse of time or both would become, an Event of Default with respect
to Securities of such series.

         Section 6.03.    CERTAIN RIGHTS OF TRUSTEE.

         Subject to the provisions of Section 601:

                  (1) the Trustee may rely and shall be protected in acting or
         refraining from acting upon any resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, note, other evidence of indebtedness

                                     38
<PAGE>

         or other paper or document believed by it to be genuine and to have
         been signed or presented by the proper party or parties;

                  (2) any request or direction of the Company mentioned herein
         shall be sufficiently evidenced by a Company Request or Company Order
         and any resolution of the Board of Directors of the Company shall be
         sufficiently evidenced by a Board Resolution of the Company;

                  (3) whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, rely upon an Officers'
         Certificate;

                  (4) the Trustee may consult with counsel and the written
         advice of such counsel or any Opinion of Counsel shall be full and
         complete authorization and protection in respect of any action taken,
         suffered or omitted by it hereunder in good faith and in reliance
         thereon;

                  (5) the Trustee shall be under no obligation to exercise any
         of the rights or powers vested in it by this Indenture at the request
         or direction of any of the Holders pursuant to this Indenture, unless
         such Holders shall have offered to the Trustee reasonable security or
         indemnity against the costs, expenses and liabilities which might be
         incurred by it in compliance with such request or direction;

                  (6) the Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, direction,
         consent, order, bond, debenture, note, other evidence of indebtedness
         or other paper or document, but the Trustee, in its discretion, may
         make such further inquiry or investigation into such facts or matters
         as it may see fit, and, if the Trustee shall determine to make such
         further inquiry or investigation, it shall be entitled to examine the
         books, records and premises of the Company, personally or by agent or
         attorney; and

                  (7) the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents or attorneys and the Trustee shall not be responsible
         for any misconduct or negligence on the part of any agent or attorney
         appointed with due care by it hereunder.

         Section 6.04.   NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

         The recitals contained herein and in the Securities (except the
Trustee's certificates of authentication) and in any coupons shall be taken as
the statements of the Company and the Trustee or any Authenticating Agent
assumes no responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons. The Trustee or any Authenticating Agent shall not be
accountable for the use or application by the Company of Securities or the
proceeds thereof.

                                     39

<PAGE>

         Section 6.05.   MAY HOLD SECURITIES.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and coupons and, subject
to Sections 608 and 613, may otherwise deal with the Company with the same
rights it would have if it were not Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other agent.

         Section 6.06.    MONEY HELD IN TRUST.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed with the Company.

         Section 6.07.    COMPENSATION AND REIMBURSEMENT.

         The Company agrees

                  (1) to pay to the Trustee from time to time reasonable
         compensation for all services rendered by it hereunder (which
         compensation shall not be limited by any provision of law in regard to
         the compensation of a trustee of an express trust);

                  (2) except as otherwise expressly provided herein, to
         reimburse the Trustee and each predecessor Trustee upon its request for
         all reasonable expenses, disbursements and advances incurred or made by
         the Trustee in accordance with any provision of this Indenture
         (including the reasonable compensation and the expenses and
         disbursements of its agents and counsel), except any such expense,
         disbursement or advance as may be attributable to its negligence or bad
         faith; and

                  (3) to indemnify the Trustee and each predecessor Trustee for,
         and to hold it harmless against, any loss, liability or expense
         incurred without negligence or bad faith on its part, arising out of or
         in connection with the acceptance or administration of the trust or
         trusts hereunder, including the costs and expenses of defending itself
         against any claim or liability in connection with the exercise or
         performance of any of its powers or duties hereunder.

         As security for the performance of the obligations of the Company under
this Section the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the benefit of the Holders of particular Securities.

         Any expenses and compensation for any services rendered by the Trustee
after the occurrence of an Event of Default specified in clause (6) or (7) of
Section 501 shall constitute expenses and compensation for services of
administration under all applicable federal or state bankruptcy, insolvency,
reorganization or other similar laws.

         The provisions of this Section shall survive the termination of this
Indenture.

         Section 6.08.    DISQUALIFICATION; CONFLICTING INTERESTS.

         If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture.

         Section 6.09.    CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

         There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States,
any State thereof or the District of Columbia, authorized under such laws to
exercise corporate trust powers, having a combined capital and surplus of at
least $50,000,000, subject to supervision or examination by Federal or State
authority. If such corporation publishes reports of condition at least annually,
pursuant to law or to the requirements of said supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article. No obligor upon any Security
issued under this Indenture or a person directly or indirectly controlling,
controlled by or under common control with such obligor shall serve as Trustee
under this Indenture.

         Section 6.10.    RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

         (b) The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

         (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series delivered to the Trustee and to the
Company.

         (d)      If at any time:

                  (1) the Trustee shall fail to comply with Section 608 after
         written request therefor by the Company or by any Holder of a Security
         who has been a bona fide Holder of a Security for at least six months,
         or

                  (2) the Trustee shall cease to be eligible under Section 609
         and shall fail to resign after written request therefor by the Company
         or by any such Holder, or

                                     41

<PAGE>

                  (3) the Trustee shall become incapable of acting or shall be
         adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
         property shall be appointed or a public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,

then, in any case, (i) the Company by a Board Resolution may remove the Trustee
with respect to all Securities, or (ii) subject to Section 514, any Holder of a
Security who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the removal of the Trustee with respect to all
Securities and the appointment of a successor Trustee or Trustees.

         (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of the Trustee for any cause,
with respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all series and that at any time there shall be only one Trustee with respect
to the Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 611, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders of Securities of such series and accepted appointment in the manner
required by Section 611, any Holder of a Security who has been a bona fide
Holder of a Security of such series for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series. Such court may thereupon, after such notice, if any,
as it may deem proper, appoint a successor Trustee.

         (f) The Company shall give notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each appointment
of a successor Trustee with respect to the Securities of any series in the
manner provided in Section 106. Each notice shall include the name of the
successor Trustee with respect to the Securities of such series and the address
of its Corporate Trust Office.

         Section 6.11.    ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee, with like effect as
if originally named

                                     42

<PAGE>

Trustee hereunder; but on the request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute
and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder. Any Trustee ceasing to act shall,
nevertheless, retain a prior lien upon all property or funds held or
collected by such Trustee to secure any amounts then due it pursuant to the
provisions of Section 607.

         (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees as co-trustees of
the same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates.

         (c) Upon request of any successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to in
paragraph (a) or (b) of this Section, as the case may be.

         (d) No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

         Section 6.12.    MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION
                          TO BUSINESS.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the

                                     43

<PAGE>

corporate trust business of the Trustee, shall be the successor of the
Trustee hereunder, PROVIDED such corporation shall be otherwise qualified and
eligible under this Article, without the execution or filing of any paper or
any further act on the part of any of the parties hereto. In case any
Securities shall have been authenticated, but not delivered, by the Trustee
then in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the
Securities so authenticated with the same effect as if such successor Trustee
had itself authenticated such Securities.

         Section 6.13.    PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

         If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

         Section 6.14.    APPOINTMENT OF AUTHENTICATING AGENT.

         The Trustee may, by an instrument in writing, appoint an Authenticating
Agent or Agents with respect to one or more series of Securities which may be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon original issue or upon exchange, registration of transfer or
partial redemption thereof or pursuant to Section 306, and Securities so
authenticated shall be entitled to the benefits of this Indenture and shall be
valid and obligatory for all purposes as if authenticated by the Trustee
hereunder. Wherever reference is made in this Indenture to the authentication
and delivery of Securities by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business under the laws of the United
States, any State thereof or the District of Columbia (or, if Bearer Securities,
organized and doing business under the laws of the country in which the Bearer
Securities are eligible), authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority (or, if
Bearer Securities, an authority of the country in which the Bearer Securities
are eligible). If such Authenticating Agent publishes reports of condition at
least annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenticating Agent shall
resign immediately in the manner and with the effect specified in this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of such Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or such Authenticating Agent.

         An Authenticating Agent may, and if it shall cease to be eligible
shall, resign at any time by giving written notice thereof to the Trustee and to
the Company. The Trustee may at any time terminate the agency of an
Authenticating Agent by giving written notice thereof to such Authenticating
Agent and to the Company. Upon receiving such notice of resignation or upon such
termination, or in case at any time such Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, the Trustee may
appoint a successor Authenticating Agent which shall be acceptable to the
Company and shall mail written notice of such appointment by first-class mail,
postage prepaid, to all Holders of Registered Securities, if any, of the series
with respect to which such Authenticating Agent will serve, as their names and
addresses appear in the Security Register. Any successor Authenticating Agent
upon acceptance of its appointment hereunder shall become vested with all the
rights, powers, and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent. No successor Authenticating Agent
shall be appointed unless eligible under the provisions of this Section.

         The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payment, subject to the
provisions of Section 607.

          If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have been endorsed thereon,
in addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

original issuance, the Trustee, if so requested by the Company in writing (which
writing need not comply with Section 102 and need not be accompanied by an
Opinion of Counsel), shall appoint in accordance with this Section an
Authenticating Agent (which, if so requested by the Company, shall be such
Affiliate of the Company) having an office in a Place of Payment designated by
the Company with respect to such series of Securities.

additional amounts payable on Securities of such series pursuant to Section
1004) shall be made at the office of the Company's Paying Agent in the Borough
of Manhattan, The City of New York, if (but only if) payment in Dollars of the
full amount of such principal, premium, interest or additional amounts, as the
case may be, at all offices or agencies outside the United States maintained for
the purpose by the Company in accordance with this Indenture is illegal or
effectively precluded by exchange controls or other similar restrictions.

         The Company may also from time to time designate one or more other
offices or agencies where Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; PROVIDED, HOWEVER, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in accordance with the requirements set forth above for Securities of any series
for such purposes. The Company will give prompt written notice to the Trustee
and the

                                     52

Holders of any such designation or rescission and of any other change in
the location of any such other office or agency.

         Section 10.03.    MONEY FOR SECURITIES PAYMENTS TO BE HELD IN
                           TRUST.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities and any coupons appertaining thereto, it
will, on or before each due date of the principal of and any premium or interest
on any of the Securities of that series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum sufficient to pay the principal
and any premium or interest so becoming due until such sums shall be paid to
such Persons or otherwise disposed of as herein provided and will promptly
notify the Trustee of its action or failure to so act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
and any premium or interest on any Securities of that series, deposit with a
Paying Agent a sum sufficient to pay the principal and any premium or interest
so becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of its action or
failure to so act.

         The Company will cause each Paying Agent for any series of Securities
(other than the Company or the Trustee) to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will (i) comply with the
provisions of the Trust Indenture Act applicable to it as a Paying Agent and
(ii) during the continuance of any default by the Company (or any other obligor
upon the Securities of that series) in the making of any payment in respect of
the Securities of that series, and upon the written request of the Trustee,
forthwith pay to the Trustee all sums held in trust by such Paying Agent for
payment in respect of the Securities of that series.

         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of and any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal and any premium or interest has become due and payable
shall be paid to the Company on Company Request (unless otherwise required by
mandatory provisions of applicable escheat or abandoned or unclaimed property
law), or (if then held by the Company) shall be discharged from such trust; and
the Holder of such Security or any coupon appertaining thereto shall (unless
otherwise required by mandatory provisions of applicable escheat or abandoned or
unclaimed property law) thereafter, as an unsecured general creditor, look only
to the Company for payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability

                                     53

<PAGE>

of the Company as trustee thereof, shall thereupon cease; PROVIDED, HOWEVER,
that the Trustee or such Paying Agent, before being required to make any such
repayment, may at the expense of the Company cause to be published once, in
an Authorized Newspaper in each Place of Payment, notice that such money
remains unclaimed and that, after a date specified therein, which shall not
be less than 30 days from the date of such publication, any unclaimed balance
of such money then remaining will be repaid to the Company.

         Section 10.04.   ADDITIONAL AMOUNTS.

         If the Securities of a series provide for the payment of additional
amounts, the Company will pay to the Holder of any Security of such series or
any coupon appertaining thereto additional amounts as provided therein. Whenever
in this Indenture there is mentioned, in any context, the payment of the
principal of or any premium or interest on, or in respect of, any Security of
any series or payment of any related coupon or the net proceeds received on the
sale or exchange of any Security of any series, such mention shall be deemed to
include mention of the payment of additional amounts provided for in this
Section to the extent that, in such context, additional amounts are, were or
would be payable in respect thereof pursuant to the provisions of this Section
and express mention of the payment of additional amounts (if applicable) in any
provisio ns hereof shall not be construed as excluding additional amounts in
those provisions hereof where such express mention is not made.

         If the Securities of a series provide for the payment of additional
amounts, at least 10 days prior to the first Interest Payment Date with respect
to that series of Securities (or if the Securities of that series will not bear
interest prior to Maturity, the first day on which a payment of principal and
any premium is made), and at least 10 days prior to each date of payment of
principal and any premium or interest if there has been any change with respect
to the matters set forth in the below-mentioned Officers' Certificate, the
Company will furnish the Trustee and the Company's principal Paying Agent or
Paying Agents, if other than the Trustee, with an Officers' Certificate
instructing the Trustee and such Paying Agent or Paying Agents whether such
payment of principal of and any premium or interest on the Securities of that
series shall be made to Holders of Securities of that series or any related
coupons who are United States Aliens without withholding for or on account of
any tax, assessment or other governmental charge described in the Securities of
that series. If any such withholding shall be required, then such Officers'
Certificate shall specify by country the amount, if any, required to be withheld
on such payments to such Holders of Securities or coupons and the Company will
pay to the Trustee or such Paying Agent the additional amounts required by this
Section. The Company covenants to indemnify the Trustee and any Paying Agent
for, and to hold them harmless against, any loss, liability or expense
reasonably incurred without negligence or bad faith on their part arising out of
or in connection with actions taken or omitted by any of them in reliance on any
Officers' Certificate furnished pursuant to this Section.

         Section 10.05.   PURCHASE OF SECURITIES BY COMPANY OR SUBSIDIARY.

         If and so long as the Securities of a series are listed on The
International Stock Exchange of the United Kingdom and the Republic of Ireland
Limited and such stock exchange shall so require, the Company will not, and will
not permit any of its Subsidiaries to, purchase any Securities of that series by
private treaty at a price (exclusive of expenses and accrued interest)

                                     54
<PAGE>

which exceeds 120% of the mean of the nominal quotations of the Securities of
that series as shown in The Stock Exchange Daily Official List for the last
trading day preceding the date of purchase.

         Section 10.06.   LIMITATION ON LIENS.

         (a) The Company will not, nor will it permit any Principal Subsidiary
to, issue, assume or guarantee any indebtedness for money borrowed (hereinafter
in this Article Ten referred to as "Debt"), if such Debt is secured by a
mortgage, pledge, security interest or lien (any mortgage, pledge, security
interest or lien being hereinafter in this Article Ten referred to as a
"mortgage" or "mortgages") upon any Principal Property of the Company or any
Principal Subsidiary or upon any shares of stock or other equity interest or
indebtedness of any Principal Subsidiary (whether such Principal Property,
shares of stock or other equity interest or indebtedness is now owned or
hereafter acquired), without in any such case effectively providing,
concurrently with the issuance, assumption or guarantee of such Debt, that the
Securities (together with, if the Company shall so determine, any other
indebtedness of or guaranteed by the Company or such Principal Subsidiary
ranking equally with the Securities then outstanding and existing or thereafter
created) shall be secured equally and ratably with (or prior to) such Debt;
PROVIDED, HOWEVER, that the foregoing restriction shall not apply to:

                  (1) mortgages on property acquired, constructed or improved by
         the Company or any Principal Subsidiary after the date of this
         Indenture which are created or assumed contemporaneously with, or
         within 180 days after, such acquisition (or in the case of property
         constructed or improved, after the completion and commencement of
         commercial operation of such property, whichever is later) to secure or
         provide for the payment of any part of the purchase price of such
         property or the cost of such construction or improvement, it being
         understood that if a commitment for such a financing is obtained prior
         to or within such 180-day period, the applicable mortgage shall be
         deemed to be included in this clause (1) whether or not such mortgage
         is created within such 180-day period; provided that in the case of any
         such construction or improvement the mortgage shall not apply to any
         property theretofore owned by the Company or any Principal Subsidiary,
         other than any theretofore unimproved real property on which the
         property so constructed, or the improvement, is located;

                  (2) mortgages on any property existing at the time of
         acquisition thereof (including mortgages on any property acquired from
         a Person which is consolidated with or merged with or into the Company
         or a Subsidiary of the Company) and mortgages outstanding at the time
         any Person becomes a Subsidiary of the Company that are not incurred in
         connection with such entity becoming a Subsidiary of the Company;

                  (3) mortgages in favor of the Company or any Principal
         Subsidiary;

                  (4) mortgages in favor of the United States, any State, any
         foreign country or any department, agency or instrumentality or
         political subdivision of any such jurisdiction, to secure partial,
         progress, advance or other payments pursuant to any contract or statute
         or to secure any indebtedness incurred for the purpose of financing all
         or any part of the purchase price or the cost of constructing or
         improving the property

                                     55

<PAGE>

         subject to such mortgages, including, without limitation, mortgages to
         secure Debt of the pollution control or industrial revenue bond type;

                  (5) mortgages on any Principal Property held, leased or used
         by the Company or any Principal Subsidiary in connection with the
         exploration for, development of, or production of (but not the
         gathering, processing, transportation or marketing of) natural gas, oil
         or other minerals; and

                  (6) any extension, renewal or replacement (or successive
         extensions, renewals or replacements), in whole or in part, of any
         mortgage referred to in any of the foregoing clauses (1), (2), (3), (4)
         and (5); PROVIDED, HOWEVER, that the principal amount of Debt secured
         thereby shall not exceed the principal amount of Debt so secured at the
         time of such extension, renewal or replacement, and that such
         extension, renewal or replacement shall be limited to all or a part of
         the property which secured the mortgage so extended, renewed or
         replaced (plus improvements on such property).

         (b) Notwithstanding the provisions of subsection (a) of this Section
1006, the Company and any Principal Subsidiary may issue, assume or guarantee
secured Debt, which would otherwise be subject to the foregoing restrictions, in
an aggregate amount which, together with all other such Debt does not exceed 15%
of Net Tangible Assets, as shown on a consolidated balance sheet, as of a date
not more than 90 days prior to the proposed transaction, prepared by the Company
in accordance with generally accepted accounting principles.

         Section 10.07.    STATEMENT BY OFFICER AS TO DEFAULT.

         (a )The Company shall deliver to the Trustee, within 120 days after the
end of each fiscal year of the Company ending after the date hereof, a brief
certificate from the principal executive officer, principal financial officer or
principal accounting officer as to his or her knowledge of the Company's
compliance with all conditions and covenants under this Indenture. For purposes
of this Section 1007, such compliance shall be determined without regard to any
period of grace or requirement of notice under this Indenture. Such certificate
shall comply with Section 314(a)(4) of the Trust Indenture Act.

         (b) The Company shall, so long as any of the Securities are
outstanding, deliver to the Trustee forthwith upon any Officer becoming aware of
any Event of Default or event which, after notice or lapse of time or both,
would become an Event of Default, an Officers' Certificate specifying such Event
of Default or event and what action the Company proposes to take with respect
thereto.

         Section 10.08.    WAIVER OF CERTAIN COVENANTS.

         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Section 1005, 1006 or Article Fifteen
with respect to the Securities of any series if before the time for such
compliance the Holders of a majority in principal amount of the Outstanding
Securities of such series shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such term,
provision or condition, but no such waiver shall extend to or affect such term,
provision or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of

                                     56

<PAGE>

the Company and the duties of the Trustee in respect of any such term,
provision or condition shall remain in full force and effect.

                            REDEMPTION OF SECURITIES

         Section 11.01.    APPLICABILITY OF ARTICLE.

         Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 301 for Securities of any series)
in accordance with this Article.

         Section 11.02.    ELECTION TO REDEEM; NOTICE TO TRUSTEE.

         The election of the Company to redeem any Securities shall be evidenced
by a Board Resolution. In the case of any redemption at the election of the
Company of less than all the Securities of any series, the Company shall, at
least 45 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date, of the principal amount of Securities of such series to be
redeemed and, if applicable, of the tenor of the Securities of such series to be
redeemed. In the case of any redemption of Securities (i) prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture, or (ii) pursuant to an election of
the Company which is subject to a condition specified in the terms of such
Securities, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction or condition.

         Section 11.03.    SELECTION OF SECURITIES TO BE REDEEMED.

         If less than all the Securities of any series are to be redeemed
(unless all of the Securities of such series of a specified tenor are to be
redeemed) the particular Securities to be redeemed shall be selected not more
than 45 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series not previously called for redemption, by such method
as the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to the minimum authorized
denomination for Securities of that series or any integral multiple thereof) of
the principal amount of Registered Securities of such series of a denomination
larger than the minimum authorized denomination for Securities of that series or
of the principal amount of global Securities of such series. If less than all of
the Securities of such series and of a specified tenor are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 45 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series and specified tenor not previously called for redemption in
accordance with the preceding sentence.

         The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

                                     57

<PAGE>

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

         Section 11.04.    NOTICE OF REDEMPTION.

         Notice of redemption shall be given in the manner provided in Section
106 to the Holders of Securities to be redeemed not less than 30 nor more than
60 days prior to the Redemption Date.

         All notices of redemption shall state:

                  (1) the Redemption Date,

                  (2) the Redemption Price,

                  (3) if less than all the Outstanding Securities of any series
         are to be redeemed, the identification (and, in the case of partial
         redemption of any Securities, the principal amounts) of the particular
         Securities to be redeemed, and that on and after the Redemption Date,
         upon surrender of the Securities, new Securities of such series in
         principal amount equal to the unredeemed part thereof will be issued,

                  (4) that on the Redemption Date the Redemption Price will
         become due and payable upon each such Security to be redeemed and, if
         applicable, that interest thereon will cease to accrue on and after
         said date,

                  (5) the place or places where such Securities, together in the
         case of Bearer Securities with all coupons appertaining thereto, if
         any, maturing after the Redemption Date, are to be surrendered for
         payment of the Redemption Price, and

                  (6) that the redemption is for a sinking fund, if such is the
         case.

         A notice of redemption published as contemplated by Section 106 need
not identify particular Registered Securities to be redeemed.

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

         Section 11.05.    DEPOSIT OF REDEMPTION PRICE.

         On or prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.

                                     58

<PAGE>

         Section 11.06.    SECURITIES PAYABLE ON REDEMPTION DATE.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest and the coupons for such
interest appertaining to any Bearer Securities so to be redeemed, except to the
extent provided below, shall be void. Upon surrender of any such Security for
redemption in accordance with said notice, together with all coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price, together with accrued interest to
the Redemption Date; PROVIDED, HOWEVER, that installments of interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only at an office or agency located outside the United States (except as
otherwise provided in Section 1002) and, unless otherwise specified as
contemplated by Section 301, only upon presentation and surrender of coupons for
such interest, and PROVIDED, FURTHER, that, unless otherwise specified as
contemplated by Section 301, installments of interest on Registered Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307.

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to the Trustee or any Paying Agent any such missing coupon in
respect of which a deduction shall have been made from the Redemption Price,
such Holder shall be entitled to receive the amount so deducted; PROVIDED,
HOWEVER, that interest represented by coupons shall be payable only at an office
or agency located outside the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate prescribed therefor in
the Security or, in the case of Original Issue Discount Securities, the
Securities' yield to maturity.

         Section 11.07.    SECURITIES REDEEMED IN PART.

         Any Registered Security which is to be redeemed only in part shall be
surrendered at a Place of Payment thereof (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or his attorney duly authorized in writing), and the Company shall execute, and
the Trustee shall authenticate and deliver to the Holder of such Security
without service charge, a new Registered Security or Securities of the same
series and of like

                                     59

<PAGE>

tenor, of any authorized denomination as requested by such Holder, in
aggregate principal amount equal to and in exchange for the unredeemed
portion of the principal of the Security so surrendered.

                                 ARTICLE TWELVE

                                  SINKING FUNDS

         Section 12.01.    APPLICABILITY OF ARTICLE.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment," and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment." If provided for by the terms of Securities of any series,
the cash amount of any sinking fund payment may be subject to reduction as
provided in Section 1202. Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

         Section 12.02.    SATISFACTION OF SINKING FUND PAYMENTS WITH
                           SECURITIES.

         The Company (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption), together in the case of any Bearer
Securities of such series with all unmatured coupons appertaining thereto, and
(2) may apply as a credit Securities of a series which have been redeemed either
at the election of the Company pursuant to the terms of such Securities or
through the application of permitted optional sinking fund payments pursuant to
the terms of such Securities, in each case in satisfaction of all or any part of
any sinking fund payment with respect to the Securities of such series required
to be made pursuant to the terms of such Securities as provided for by the terms
of such series; PROVIDED that such Securities have not been previously so
credited. Such Securities shall be received and credited for such purpose by the
Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly.

         Section 12.03.    REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee a Company Order
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 1202 and will also deliver to the Trustee any Securities to be so
credited. Not less than 45 days before each such sinking fund payment date the
Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner

                                     60

<PAGE>

provided in Section 1104. Such notice having been duly given, the redemption
of such Securities shall be made upon the terms and in the manner stated in
Sections 1106 and 1107.

                                ARTICLE THIRTEEN

                           DEFEASANCE.

         The Company may at its option by Board Resolution, at any time, elect
to have either Section 1302 or Section 1303 applied to the Outstanding
Securities of any series upon compliance with the conditions set forth below in
this Article Thirteen.

         Section 13.02.    DEFEASANCE AND DISCHARGE.

         Upon the Company's exercise of the option provided in Section 1301
applicable to this Section, the Company shall be deemed to have been discharged
from its obligations with respect to the Outstanding Securities of any series on
the date the conditions set forth below are satisfied (hereinafter,
"defeasance"). For this purpose, such defeasance means that the Company shall be
deemed to have paid and discharged the entire indebtedness represented by the
Outstanding Securities of such series and to have satisfied all its other
obligations under the Securities of such series and this Indenture insofar as
the Securities of such series are concerned (and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging the same), except
for the following which shall survive until otherwise terminated or discharged
hereunder: (A) the rights of Holders of the Securities of such series to
receive, solely from the trust fund described in Section 1304 and as more fully
set forth in such Section, payments in respect of the principal of and any
premium and interest on the Securities of such series when such payments are
due, (B) the Company's obligations with respect to such Securities under
Sections 304, 305, 306, 1002, 1003 and 1004, (C) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (D) this Article Thirteen.
Subject to compliance with this Article Thirteen, the Company may exercise its
option under this Section 1302 notwithstanding the prior exercise of its option
under Section 1303.

         Section 13.03.    COVENANT DEFEASANCE.

         Upon the Company's exercise of the option provided in Section 1301
applicable to this Section, (i) the Company shall be released from its
obligations with respect to the Securities of such series under Sections 801,
1005 and 1006 and (ii) the occurrence of an event specified in Sections 501(3)
or (5) shall not be deemed to be an Event of Default on and after the date the
conditions set forth below are satisfied (hereinafter, "covenant defeasance"),
but the remainder of this Indenture and such Securities shall be unaffected
thereby. For this purpose, such covenant defeasance means that the Company may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such Section or clause whether directly
or indirectly by reason of any reference elsewhere herein to any such Section or
clause or by reason of any reference in any such Section or clause to any other
provision herein or in any such Section or clause to any other provision herein
or in any other document, but the remainder of this Indenture and such
Securities shall be unaffected thereby.

         Section 13.04.    CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

         The following shall be the conditions to application of either Section
1302 or Section 1303 to the then Outstanding Securities of any series:

                  (1) The Company shall irrevocably have deposited or caused to
         be deposited with the Trustee (or another trustee satisfying the
         requirements of Section 609 who shall agree to comply with the
         provisions of this Article Thirteen applicable to it) as trust funds in
         trust for the purpose of making the following payments specifically
         pledged as security for, and dedicated solely to, the benefit of the
         Holders of the Securities of such series, (A) money in an amount, or
         (B) U.S. Government Obligations which through the scheduled payment of
         principal and interest in respect thereof in accordance with their
         terms will provide, not later than one day before the due date of any
         payment, money in an amount, or (C) a combination thereof, sufficient,
         in the opinion of a nationally recognized firm of independent public
         accountants expressed in a written certification thereof delivered to
         the Trustee, to pay and discharge, and which shall be applied by the
         Trustee (or other qualifying trustee) to pay and discharge, the
         principal of (and premium, if any) and each installment of interest on
         the Securities and any coupons pertaining thereto on the Stated
         Maturity of such principal (and premium, if any) or installment of
         interest in accordance with the terms of this Indenture and of the
         Securities of such series. For this purpose, "U.S. Government
         Obligations" means securities that are (x) direct obligations of the
         United States for the payment of which its full faith and credit is
         pledged or (y) obligations of a Person controlled or supervised by and
         acting as an agency or instrumentality of the United States the payment
         of which is unconditionally guaranteed as a full faith and credit
         obligation by the United States, which, in either case, are not
         callable or redeemable at the option of the issuer thereof, and shall
         also include a depository receipt issued by a bank (as defined in
         Section 3(a)(2) of the Securities Act of 1933, as amended) as custodian
         with respect to any such U.S. Government Obligation or a specific
         payment of principal of or interest on any such U.S. Government
         Obligation held by such custodian for the account of the holder of such
         depository receipt, PROVIDED that (except as required by law) such
         custodian is not authorized to make any deduction from the amount
         payable to the holder of such depository receipt from any amount
         received by the custodian in respect of the U.S. Government Obligation
         or the specific payment of principal of or interest on the U.S.
         Government Obligation evidenced by such depository receipt.

                  (2) In the case of an election under Section 1302, the Company
         shall have delivered to the Trustee an Opinion of Counsel stating that
         (x) the Company has received from, or there has been published by, the
         Internal Revenue Service a ruling, or (y) since the date of this
         Indenture there has been a change in the applicable United States
         Federal income tax law, in either case to the effect that, and based
         thereon such opinion shall confirm that, the Holders of the Outstanding
         Securities of such series will not recognize income, gain or loss for
         United States Federal income tax purposes as a result of such deposit,
         defeasance and discharge and will be subject to United States Federal
         income tax on the same amounts, in the same manner and at the same
         times as would have been the case if such deposit, defeasance and
         discharge had not occurred.

                                     62

<PAGE>

                  (3) In the case of an election under Section 1303, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that the Holders of the Outstanding Securities of such series will not
         recognize gain or loss for United States Federal income tax purposes as
         a result of such deposit and covenant defeasance and will be subject to
         United States Federal income tax on the same amount, in the same manner
         and at the same times as would have been the case if such deposit and
         covenant defeasance had not occurred.

                  (4) No Event of Default or event which with notice or lapse of
         time or both would become an Event of Default with respect to the
         Securities of such series shall have occurred and be continuing on the
         date of such deposit or, insofar as subsections 501(6) and (7) are
         concerned, at any time during the period ending on the 121st day after
         the date of such deposit (it being understood that this condition shall
         not be deemed satisfied until the expiration of such period).

                  (5) Such defeasance or covenant defeasance shall not cause the
         Trustee to have a conflicting interest within the meaning of the Trust
         Indenture Act with respect to any securities of the Company.

                  (6) Such defeasance or covenant defeasance shall not result in
         a breach or violation of, or constitute a default under, any other
         agreement or instrument to which the Company is a party or by which it
         is bound.

                  (7) The Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that all
         conditions precedent provided for relating to either the defeasance
         under Section 1302 or the covenant defeasance under Section 1303 (as
         the case may be) have been complied with.

                  (8) Such defeasance or covenant defeasance shall not result in
         the trust arising from such deposit constituting an investment company
         as defined in the Investment Company Act of 1940, as amended, or such
         trust shall be qualified under such Act or exempt from regulation
         thereunder.

         Section 13.05.    DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS
                           TO BE HELD IN TRUST; OTHER MISCELLANEOUS PROVISIONS.

         Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee (or other qualifying trustee -- collectively, for purposes of
this Section 1305, the "Trustee") pursuant to Section 1304 in respect of the
Securities of such series shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities of such series and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of the Securities of such series, of all sums due and
to become due thereon in respect of principal (and premium, if any) and
interest, but such money need not be segregated from other funds except to the
extent required by law.

                                     63

<PAGE>

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1304 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the Outstanding Securities.

         Anything in this Article Thirteen to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 1304 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent defeasance or covenant
defeasance.

         Section 13.06.    REINSTATEMENT.

         If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 1302 or 1303 by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Company's obligations under this Indenture and the
Securities of such series shall be revived and reinstated as though no deposit
had occurred pursuant to this Article Thirteen until such time as the Trustee or
Paying Agent is permitted to apply all such money in accordance with Section
1302 or 1303; PROVIDED, HOWEVER, that if the Company makes any payment of
principal of or any premium or interest on any Security following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of the Securities of such series to receive such payment from the
money held by the Trustee or the Paying Agent.

                    MEETINGS OF HOLDERS OF BEARER SECURITIES

         Section 14.01.    PURPOSES FOR WHICH MEETINGS MAY BE CALLED.

         If Securities of a series are issuable as Bearer Securities, a meeting
of Holders of Securities of such series may be called at any time and from time
to time pursuant to this Article to make, give or take any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be made, given or taken by Holders of Securities of such

         (a) The Trustee may at any time call a meeting of Holders of Bearer
Securities of any series for any purpose specified in Section 1401, to be held

the Holders of at least 10% in aggregate principal amount of the Outstanding
Bearer Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 1401, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have made the
first publication of the notice of such meeting within 21 days after receipt of
such request or shall not thereafter proceed to cause the meeting to be held as

place in the Borough of Manhattan, The City of New York, or in London or such
other location as the Trustee shall determine for such meeting and may call such
meeting for such purposes by giving notice thereof as provided in subsection (a)
of this Section.

         Section 14.03.    PERSONS ENTITLED TO VOTE AT MEETINGS.

         To be entitled to vote at any meeting of Holders of Bearer Securities a
Person shall (a) be a Holder of one or more Bearer Securities or (b) be a Person
appointed by an instrument in writing as proxy by a Holder of one or more Bearer

meeting of Holders of Securities of such series. In the absence of a quorum
within 30 minutes of the time appointed for any such meeting, the meeting shall,
if convened at the request of Holders of Securities of such series, be
dissolved. In any other case the meeting may be adjourned for a period of not
less than 10 days as determined by the chairman of the meeting prior to the
adjournment of such meeting. In the absence of a quorum at any such adjourned
meeting, such adjourned meeting may be further adjourned for a period of not
less than 10 days as determined by the chairman of the meeting prior to the
adjournment of such adjourned meeting. Notice of the reconvening of any
adjourned meeting shall be given as provided in Section 1402(a), except that
such notice need be given only once not less than five days prior to the date on
which the meeting is scheduled to be reconvened. Notice of the reconvening of an
adjourned meeting shall state expressly the percentage, as provided above, of
the aggregate principal amount of the Outstanding Securities of such series
which shall constitute a quorum.

         Except as limited by Section 512 or the proviso to the first paragraph
of Section 902, any resolution presented to a meeting (or adjourned meeting duly
reconvened at which a quorum is present as aforesaid) may be adopted by the
affirmative vote of the Holders of a majority in principal amount of the
Outstanding Bearer Securities of that series; provided, however, that any
resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other action which this Indenture expressly provides
may be made, given or taken by the Holders of a specified percentage, which is
less than a majority, in aggregate principal amount of the Outstanding Bearer
Securities of a series may be adopted at a meeting (or an adjourned meeting duly
reconvened and at which a quorum is present as aforesaid) by the affirmative
vote

                                     65

<PAGE>

of the Holders of such specified percentage in principal amount of the
Outstanding Bearer Securities of that series.

         To the extent consistent with the terms of this Indenture, any
resolution passed or decision taken at any meeting of Holders of Bearer
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the related coupons,
whether or not present or represented at the meeting.

         SECTION 14.05.    DETERMINATION OF VOTING RIGHTS; CONDUCT AND
                           ADJOURNMENT OF MEETINGS.

         (a) Notwithstanding any other provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Bearer Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding
of Bearer Securities shall be proved in the manner specified in Section 104 and
the appointment of any proxy shall be proved in the manner specified in Section
104 or by having the signature of the Person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 104 to
certify to the holding of Bearer Securities. Such regulations may provide that
written instruments appointing proxies, regular on their face, may be presumed
valid and genuine without the proof specified in Section 104 or other proof.

         (b) The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Bearer Securities as provided in Section 1402(b), in
which case the Company or the Holders of Bearer Securities of the series calling
the meeting, as the case may be, shall in like manner appoint a temporary
chairman. A permanent chairman and a permanent secretary of the meeting shall be
elected by vote of the Persons entitled to vote a majority in aggregate
principal amount of the Outstanding Securities of such series represented at the
meeting.

         (c) At any meeting each Holder of a Security of such series or proxy
shall be entitled to one vote for each $1,000 principal amount of the
Outstanding Securities of such series held or represented by him; provided,
HOWEVER, that no vote shall be cast or counted at any meeting in respect of any
Bearer Security challenged as not Outstanding and ruled by the chairman of the
meeting to be not Outstanding. The chairman of the meeting shall have no right
to vote, except as a Holder of a Security of such series or proxy.

         (d) Any meeting of Holders of Bearer Securities of any series duly
called pursuant to Section 1402 at which a quorum is present may be adjourned
from time to time by Persons entitled to vote a majority in principal amount of
the Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

Bearer Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting. A record, at least in
duplicate, of the proceedings of each meeting of Holders of Bearer Securities of
any series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1402 and, if
applicable, Section 1404. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

                               (the "Securities")

         This is to certify that as of the date hereof, and except as set forth

         If the Securities are of the category contemplated in Section

                                  THE PREMISES

         2.01 Landlord, in consideration of the rents to be paid and the
covenants and agreements to be performed by Tenant, hereby leases to Tenant the
premises set forth in Section 1.01(e) (the "Premises") in the building(s) (the
"Building") described in Section 1.01(d), together with the right to use the
parking and common areas and facilities which may be furnished from time to time
by Landlord (collectively the "Common Areas"), including, without limitation,
all common elevators, hallways and stairwells located within the Building, and
all common parking facilities, driveways and sidewalks, in common with Landlord
and with the tenants and occupants of the Project, their agents, employees,
customers, clients and invitees. Tenant agrees that the Premises and the
Building shall be deemed to include the number of rentable square feet set forth
in Section 1.01(h) and in no event shall Tenant have the right to challenge,
demand, request or receive any change in the base rent or other sums due
hereunder as a result of any claimed or actual error or omission in the rentable
or usable square footage of the Premises, the Building or the Project. Landlord
reserves the right at any time and from time to time to make alterations or
additions to the Building or the Common Areas, and to demolish improvements on
and to build additional improvements on the land surrounding the Building during
which time Tenant shall continue to have access to the Building and the Premises
and Tenant's use of the Premises shall not be materially adversely affected and
to add or change the name of the Building from time to time, in its sole
discretion without the consent of Tenant and the same shall not be construed as
a breach of this Lease. The Building, the other buildings listed in Section
1.01(d), the Common Areas and the land surrounding the Building and the Common
Areas are hereinafter collectively referred to as the "Project". If Landlord
decides to change the name of the building Landlord will notify Tenant in
writing 60 days prior to such name change.

         2.02 Landlord agrees to construct the improvements to the Premises (the
"Tenant Improvements") in accordance with the space plan(s) (as it may be
amended by approved change orders, the "Plans"), attached as Exhibit "A". All
material changes from the Plans which Landlord determines are necessary during
construction shall be submitted to Tenant for Tenant's approval or rejection. If
Tenant fails to notify Landlord of Tenant's approval or rejection of such
changes within five (5) days of receipt thereof, Tenant shall be conclusively
deemed to have approved such changes. Landlord's approval of the Plans shall not
constitute a representation, warranty or agreement (and Landlord shall have no
responsibility or liability for) the completeness or design sufficiency of the
Plans or the Tenant Improvements, or the compliance of the Plans or Tenant
Improvements with any laws, rules or regulations of any governmental or other
authority.

         2.03 The provisions of Exhibit E, special provisions, shall govern the
cost of constructing Tenant Improvements.

         2.04 (a) Landlord, at its sole cost and expense, shall construct the
base building shell and core elements of the building described on Exhibit E
without reimbursement from the Tenant Improvement Allowance (as defined below).

Landlord intends to construct the Tenant Improvements with no fee for
construction management and deliver the Premises "ready for occupancy" (as
defined below) to Tenant on the Scheduled Occupancy Date set forth in Paragraph
1.01(f). The Premises will be conclusively deemed "ready for occupancy" on the
earlier to occur of when: (i) the work to be done under this Paragraph has been
substantially completed and after the issuance of a conditional or temporary
certificate of occupancy for the Premises by the appropriate government agency
within whose jurisdiction the Building is located, or (ii) when Tenant takes
possession of the Premises. The Premises will not be considered unready or
incomplete if only minor or insubstantial details of construction, decoration or
mechanical adjustments remain to be done within the Premises or Common Areas of
the Building, or if only landscaping or exterior trim remains to be done outside
the Premises, or if the delay in the availability of the Premises for Tenant's
occupancy is caused in whole or in material part by Tenant. By occupying the
Premises, Tenant will be deemed to have accepted the Premises and to have
acknowledged that they are in the condition called for in this Lease, subject
only to "punch list" items (as the term "punch list" is customarily used in the
construction industry in the area where the Project is located) identified by
Tenant by written notice delivered to Landlord within ten (10) days after the
date Landlord tenders possession of the Premises to Tenant. If in good faith
Landlord is delayed or hindered in construction by any labor dispute, strike,
lockout, fire, unavailability of material, severe weather, acts of God,
restrictive governmental laws or regulations, riots, insurrection, war or other
casualty or events of a similar nature beyond its reasonable control ("Force
Majeure"), the date for the delivery of the Premises to Tenant "ready for
occupancy" shall be extended for the period of delay caused by the Force
Majeure. If Landlord is delayed or hindered in construction as a result of
change orders or other requests by, or acts of, Tenant ("Tenant Delay") the date
for the delivery of the Premises to Tenant "ready for occupancy" shall be
extended by the number of days of delay caused by Tenant Delay. The Scheduled
Occupancy Date as extended as a result of the occurrence of a

                                       2
<PAGE>

Force Majeure or Tenant Delay or with the consent of Tenant, is herein referred
to as the Occupancy Date.

(b) Landlord shall construct the Tenant Improvements in accordance with the
space plans to be developed by Landlord and Tenant. Landlord intends to deliver
the Premises Ready for Occupancy to Tenant on or before March 1, 2001 (the
"Occupancy Date"). The Occupancy Date is predicated upon the strict adherence to
all of the following scheduling requirements (the "Time Schedule Items"): (i)
the construction of the Tenant Improvements shall not include any long lead
items for which the delivery of said item to the Premises exceeds fifteen (15)
business days following acknowledgment of order by vendor; and (ii) Tenant shall
have accepted final Space Plans not later than by December 1, 2000. In the event
Tenant shall not have accepted final Space Plans not later than by December 1,
2000, then Landlord anticipates that the Premises will not be "Ready for
Occupancy" until ninety (90) days after Tenant Accepts the Final Space Plans,
absent any additional Tenant Delay or Force Majeure, and in all events Base
Monthly Rent shall commence not later than March 1, 2001 regardless of whether
the Tenant Improvements are complete or Tenant occupies the space. Noncompliance
with any Time Schedule Items shall be deemed to be a Tenant Delay.

                                   SECTION 3.

                                    THE TERM

         3.01 The initial term of this Lease (the "Initial Term or "Term"") will
commence (the "Commencement Date") on the earlier of: (i) the date Tenant takes
possession of the Premises; or (ii) the Occupancy Date; (iii) the date the
Occupancy Date would have occurred in the absence of Tenant Delay. Unless sooner
terminated or extended in accordance with the terms hereof, the Lease will
terminate the number of Lease Years and Months set forth in Paragraph 1.01(f)
after the Commencement Date. If the Commencement Date is other than the first
day of a calendar month, the first Lease Year shall begin on the first day of
the first full calendar month following the Commencement Date. Upon request by
Landlord, Tenant will execute a written instrument confirming the Commencement
Date and the expiration date of the Initial Term.

                                   SECTION 4.

                                  THE BASE RENT

         4.01 From and after the Commencement Date, Tenant agrees to pay to
Landlord, as minimum net rental for the Initial Term and Option Terms of this
Lease, the sum(s) set forth in Paragraph 1.01(g) (the "Base Rent"). The term
"Lease Year" as used herein shall be defined to mean a period of twelve (12)
consecutive calendar months. The first Lease Year shall begin on the date
determined in accordance with Section 3.01. Each succeeding Lease Year shall
commence on the anniversary date of the first Lease Year.

         4.02 Base Rent and other sums due Landlord hereunder shall be paid by
Tenant to Landlord in equal monthly installments (except as otherwise provided
herein), in advance, without demand and without any setoffs or deductions
whatsoever, on the first day of each and every calendar month (the "Rent Day")
during the Initial Term and Option Terms, if any, at the office of Manager as
set forth in Section 1.01(c), or at such other place as Landlord from time to
time may designate in writing. In the event the Commencement Date is other than
the first day of a calendar month, the Base Rent for the partial first calendar
month of the Initial Term will be prorated on a daily basis based on the number
of days in the calendar month and will be paid in addition to the rent provided
in Paragraph 4.01 above. Base Rent for such partial calendar month and for the
first full calendar month of the first Lease Year shall be paid upon the
execution of this Lease by Tenant.

                                   SECTION 5.

                            LATE CHARGES AND INTEREST

         5.01 Any rent or other sums payable by Tenant to Landlord under this
Lease which are not paid within five (5) days after they are due and written
notice has been provided to Tenant (but if one notice has been given in any
twelve (12) month period, no further notice shall be required during such twelve
(12) month period), will be subject to a late charge of ten (10%) percent of the
amount due. Such late charges will be due and payable as additional rent on or
before the next Rent Day.

         5.02 Any rent, late charges or other sums payable by Tenant to Landlord
under this Lease not paid within ten (10) days after the same are due will bear
interest at a per annum rate equal to the lower of: (i) eighteen (18%) percent
per annum, or (ii) the highest rate permitted by law. Such interest will be due
and payable as additional rent on or before the next Rent Day, and will accrue
from the date that such

                                       3
<PAGE>

rent, late charges or other sums are payable under the provisions of this Lease
until actually paid by Tenant.

         5.03 Any default in the payment of rent, late charges or other sums
will not be considered cured unless and until the late charges and interest due
hereunder are paid by Tenant to Landlord. If Tenant defaults in paying such late
charges and/or interest, Landlord will have the same remedies as Landlord would
have if Tenant had defaulted in the payment of rent. The obligation hereunder to
pay late charges and interest will exist in addition to, and not in the place
of, the other default provisions of this Lease.

                                   SECTION 6.

                    OPERATING EXPENSES, UTILITIES, AND TAXES

         6.01 In the event that Operating Expenses for the Project, in any
calendar year, exceed the Operating Expenses for the Base Year (as defined in
Paragraph 1.01(l)), Tenant shall pay to Landlord, as additional rent, Tenant's
Proportionate Share (as defined in Paragraph 1.01(h)) of any such excess.
Tenant's obligations hereunder shall be pro-rated for any calendar year in which
Tenant is obligated to pay rent for only a portion thereof. For the purposes of
this Section, the term "Operating Expenses" shall mean and include those
expenses paid or incurred by Landlord for: maintaining, operating, owning, and

and applicable to the Project); painting, uniforms, management fees, supplies,

hospitalization, welfare or retirement plans, or any other similar or like
expenses incurred under the provisions of any collective bargaining agreement,

benefits for employees so engaged in the operation, maintenance and repair of
the Project; the charges of any independent contractor who, under contract with
Landlord or its representatives, does any of the work of operating, maintaining
or repairing the Project; capital expenditures required under any governmental
law or regulation; legal and accounting expenses including, but not limited to,
such expenses as relate to seeking or obtaining reductions in, and refunds of,
real estate taxes; or any other expenses or charges, whether or not hereinbefore
mentioned, which in accordance with generally accepted accounting and management
principles would be considered as an expense of maintaining, operating, owning
or repairing the Project.

The term "Operating Expenses" shall not include the following items:

                  (1) The cost of repairs and general maintenance due to
casualty or condemnation paid by proceeds of insurance, by Tenant or by other
third parties, and the cost of alterations attributable solely to tenants other

                  (2) Any ground lease rental or mortgage principal or interest;

                  (3) Costs, including permit, license and inspection costs,

are included in connection with the common areas) or to correct defects in the
construction of the Project;

                  (4) Depreciation and amortization, except on materials, tools,
supplies and vendor type equipment purchased by Landlord to enable Landlord to
supply services Landlord might otherwise contract for with a third party, where
such depreciation and amortization would otherwise have been included in the
charge for such third party's services, all as determined in accordance with
generally accepted accounting principles ("GAAP") consistently applied and
amortized over the reasonable useful life;

                  (5) Attorney's fees and accountants' fees incurred in
connection with disputes with present tenants or other occupants of the Project
(not including disputes, the resolution of which would directly benefit all
tenants in the Project);

                  (6) Except as otherwise set forth above, the costs of new (as
opposed to replacement) capital improvements; provided, the amortization of the
cost of capital improvements which are in replacement of existing capital
improvements shall be amortized over the reasonable useful life;

                                       4
<PAGE>

                  (7) Amounts paid or incurred by Landlord to affiliates in

or for supplies or materials at other first class office buildings in the area;

                  (8) Interest, principal, points and fees on debt or
amortization on any mortgage or mortgages or any other debt instrument
encumbering this lease or the Project;

                  (9) All items and services for which Tenant or any other
tenant of the Project reimburses Landlord, including costs of excess or
additional services provided to any tenant that are directly billed to such
tenant;

                  (10) Tax penalties incurred as a result of Landlord's
negligence or inability or unwillingness to make payments when due;

                  (11) Landlord's general corporate overhead and general
administrative expenses other than those permitted in this Lease;

                  (12) Any political or charitable contributions made by
Landlord;

                  (13) Any amount for which Landlord receives reimbursement from
others, including without limitation, from insurers;

                  (14) Tenant Improvements and leasing commission incurred in
leasing office or other space in the Project;

                  (15) Expenses incurred in connection with services above
Building Standards of the type that are not provided to Tenant but which are
provided to other tenant(s) of the Building of Project;

                  (16) Lights and power costs for individual tenant premises.

                  (17) Collector quality art work but Operating Expenses will
include reasonable and customary decorations.

         6.02 If the Project is not fully rented during all or a portion of any
year (including the Base Year), then Landlord shall elect to make an appropriate
adjustment of the Operating Expenses and Real Estate Taxes (as defined below)
for such year and for the Base Year employing sound accounting and management
principles, to determine the amount of Operating Expenses and Real Estate Taxes
that would have been paid or incurred by Landlord had the Project been fully
rented; and the amount so determined shall be deemed to have been the amount of
Operating Expenses and Real Estate Taxes for such year. If any expenses relating
to the Project, though paid in one year, relate to more than one calendar year,
at the option of Landlord such expense may be proportionately allocated among
such related calendar years. In addition, in the event any Operating Expense or
Real Estate Tax applies to only some portion of the Project or is partially
allocable to other buildings or projects, Landlord may allocate such expense
among such buildings and projects in accordance with sound accounting and
management principles to determine the amount of Operating Expenses and Real
Estate Taxes for the Project and the Building.

         6.03 In the event that Real Estate Taxes (as hereinafter defined) for
the Project, in any calendar year, exceed the Real Estate Taxes for the Base
Year, Tenant shall pay to Landlord, as additional rent, Tenant's Proportionate
Share of any such excess over and above the Base Real Estate Taxes (as
hereinafter defined). The "Base Real Estate Taxes" shall be the Real Estate
Taxes shown on the bills for which the "due date" occurs in the Base Year. "Real
Estate Taxes" as used herein shall mean real estate taxes, assessments (general,
special, ordinary or extraordinary) sewer rents, rates and charges, taxes based
upon the receipt of rent, and any other federal, state or local charge (general,
special, ordinary or extraordinary) which may now or hereafter be imposed,
levied or assessed against the Project or any part thereof, or on any building
or improvements at any time situated thereon. In the event the State of Michigan
or any political subdivision thereof having taxing authority shall modify,
repeal or abolish the ad valorem tax on real property, or impose a tax or
assessment of any kind or nature upon, against, or with respect to the Project
or the rents payable by Tenant or on the income derived from the Project, or
with respect to Landlord's ownership interest in the Project, which tax is
assessed or imposed by way of substitution for or in addition to all or any part
of the Real Estate Taxes, then such tax or assessment shall be included within
the definitions of "Real Estate Taxes"; provided, however, nothing herein
contained shall impose an obligation on Tenant to pay the general income tax or
Michigan Single Business Tax liabilities of Landlord, except to the extent such
a tax is being used to fund governmental functions presently or previously
funded by ad valorem taxes on real property.

         6.04 At any time and from time to time, Landlord may reasonably
estimate the amount by which current Real Estate Taxes and Operating Expenses
are expected to exceed the Real Estate Taxes

                                       5
<PAGE>

and Operating Expenses for the Base Year (the "Estimated Excess Expenses").
Tenant shall pay its Proportionate Share of the Estimated Excess Expenses by
depositing with Landlord on each Rent Day during the term hereof an amount
equal to one-twelfth (1/12) of its annual share of the Estimated Excess
Expenses. Landlord shall deliver to Tenant, within a reasonable period of
time after the close of each calendar year, an annual statement indicating
the amount by which the Real Estate Taxes and Operating Expenses actually
incurred in that calendar year exceed the Real Estate Taxes and Operating
Expenses for the Base Year (the "Actual Excess Expenses"). In the event that
the Actual Excess Expenses exceed the Estimated Excess Expenses, Tenant shall
pay Tenant's Proportionate Share of the difference to Landlord within fifteen
(15) days of delivery of the annual statement. In the event that Estimated
Excess Expenses exceed Actual Excess Expenses, then at Landlord's option
Tenant shall either be reimbursed to the extent that Tenant's payments toward
Tenant's share of the Estimated Excess Expenses exceed Tenant's Proportionate
Share of the Actual Excess Expenses, or Tenant shall be granted a
corresponding credit against the Base Rent or other sums next due Landlord
hereunder.

         6.05 Tenant shall be responsible for and pay before delinquent all
municipal, county, and state taxes assessed, levied or imposed during the term
of this Lease, and all extensions thereof, upon the leasehold interest and all
furniture, fixtures, machinery, equipment, apparatus, systems and all other
personal property of any kind whatsoever located at, placed in or used in
connection with the Premises.

         6.06 Landlord agrees with Tenant that Landlord will furnish heat and
air conditioning during normal business hours (8:00 a.m. to 6:00 p.m. Monday
through Friday and Saturday 9:00 a.m. to 2:00 p.m., excluding Building
holidays), usual and customary janitorial services, as set forth in Exhibit "C",
and provide water and sewer service to the Premises and hot and cold water for
ordinary lavatory purposes in the common area restrooms. However, if Tenant uses
or consumes water for any other purpose or in unusual quantities (of which fact
Landlord shall be the sole judge) Landlord may install a water meter at Tenant's
expense which Tenant shall thereafter maintain at Tenant's expense in good
working order and repair, to register such water consumption. Tenant shall pay
for the quantity of water shown on said meter, together with the sewer rents,
debt service and other charges made by the local utilities for water and sewer
service, as additional rent, at the secondary rate per gallon (general service
rate) established by the applicable governmental authority or the applicable
utility company providing the water. Whenever machines or equipment which
generate heat are used in the Premises which affect the temperature otherwise
maintained by the air-conditioning system, Landlord reserves the right to
install supplementary air-conditioning equipment in the Premises, and the cost
thereof, and the expense of operation and maintenance thereof, shall be paid by
Tenant to Landlord. Although Landlord will provide air-conditioning and/or heat
upon the prior request of Tenant in accordance with Building practices for hours
other than regular business hours, Tenant will pay Landlord's charges for
providing such service. Said charges shall include a cost equal to the cost to
operate the equipment for Tenant's expanded business hours and days, and
Landlord's maintenance, equipment amortization and other appropriate charges
which Landlord determines are attributable to operating the equipment for
periods in excess of the normal business hours described above.

         6.07 Tenant shall pay all charges made against the Premises for
electricity used upon or furnished to the Premises as and when due during the
continuance of this Lease. To the extent electricity is not separately metered
for the Premises, Landlord shall make a determination of Tenant's usage of
electricity supplied to the Building, and Tenant agrees to pay for such
electricity within thirty (30) days after request therefor from Landlord.
Whether or not metered, Tenant shall pay for the electricity at the secondary
rate (general service rate) established by the applicable governmental authority
or the applicable utility company providing the electricity. Tenant shall also
pay for fluorescent or other electric light bulbs or tubes and electric
equipment used in the leased Premises.

                                   SECTION 7.

                                 USE OF PREMISES

         7.01 Tenant shall occupy and use the Premises during the Term for the
purposes set forth in Section 1.01(m) only, and for no other purpose without the
prior written consent of Landlord. Tenant agrees that it will not use or permit
any person to use the Premises or any part thereof for any use or purpose in
violation of the laws of the United States, the laws, ordinances or other
regulations of the State or municipality in which the Premises are located, or
of any other lawful authorities, or any building and use restrictions, now or
hereafter affecting the Premises or any part thereof.

         7.02 Tenant will not do or permit any act or thing to be done in or to
the Premises or the Project which will invalidate or be in conflict with any
terms or conditions required to be contained in any property or casualty
insurance policy authorized to be issued in the State of Michigan or any term or
condition of the Insurance Services Office's (ISO) Commercial Property Insurance
and/or Commercial General Liability Insurance Conditions or any different or
additional terms and conditions of any insurance policy in effect on the
Premises or the Project from time to time (collectively the "Building
Insurance"), Nor shall Tenant do nor permit any other act or thing to be done in
or to the Premises or the Project which

                                       6
<PAGE>

shall or might subject Landlord to any liability or responsibility to any person
or for property damage, nor shall Tenant use the Premises or keep anything on or
in the Project except as now or hereafter permitted by the fire regulations, the
fire department or zoning, health, safety, land use or other regulations.
Tenant, at Tenant's sole cost and expense, shall comply with all requirements
and recommendations set forth by any property or casualty insurer or reinsurer
providing coverage for the Premises or the Project or by any person or entity
engaged by Landlord or Manager to perform any loss control, analysis or
assessment for the Premises or the Project. Tenant shall not do or permit
anything to be done in or upon the Premises or the Project or bring or keep
anything therein or use the Premises or the Project in a manner which increases
the rate of premium for any Building Insurance or any property or equipment
located therein over the rate in effect at the commencement of the Term of this
Lease. In addition, Tenant agrees to pay Landlord the amount of any increase in
premiums for insurance which may be charged during the term of this Lease
resulting from the act or omissions of Tenant or the character or nature of its
occupancy or use of the Project or the Premises, whether or not Landlord has
consented to the same. Any scheduled or "make-up" of any insurance rate for the
Premises, the Building or the Project issued by any insurance company
establishing insurance premium rates for the Premises, Building or the Project
shall be PRIMA FACIE evidence of the facts therein stated and of the several
items and charges in the insurance premium rates then applicable to the
Premises, the Building or the Project. Tenant shall give Landlord notice
promptly after Tenant learns of any accident, emergency, or occurrence for which
Landlord is or may be liable, or any fire or other casualty or damage or defects
to the Premises, the Building or the Project which Landlord is or may be
responsible or which constitutes the property of Landlord.

         7.03 Tenant shall not perform acts or carry on any activities or engage
in any practices which may injure the Premises or any portion of the Project or
which may be a nuisance or menace to other persons on or in the Project. Tenant
shall pay all costs, expenses, fines, penalties, or damages which may be imposed
upon Landlord by reason of Tenant's failure to comply with the provisions of
this Section.

         7.04 Tenant will not place any load upon any floor of the Premises
exceeding the floor load per square foot area which it was designed to carry and
which is allowed by law. Landlord reserves the right to prescribe the weight and
position of all safes, business machines and mechanical equipment. Such items
shall be placed and maintained by Tenant, at Tenant's expense, in settings
sufficient in Landlord's judgment, to absorb and prevent vibration, noise and
annoyance. If at any time any windows of the Premises are temporarily or
permanently closed, darkened or covered for any reason whatsoever, including
Landlord's own acts, Landlord shall not be liable for any damage Tenant may
sustain thereby, and the same shall not be considered a default under this Lease
and Tenant shall not be entitled to any compensation therefore nor abatement of
any Base Rent or any other sums due hereunder, nor shall the same release Tenant
from its obligations hereunder nor constitute an eviction, construction, actual
or otherwise.

         7.05 During the term hereof, and consistent with janitorial services
provided by Landlord, Tenant will keep the Premises in a clean and wholesome
condition, will use the same in a careful and proper manner, and generally will
comply with all laws, ordinances, orders and regulations affecting the Premises
and the cleanliness, safety, occupancy and use thereof. Tenant will not commit
waste in or on the Premises, and will use the Premises in accordance with the
Rules and Regulations of the Project, as set forth in Exhibit B, attached hereto
and made a part hereof.

         7.06 As between Landlord and Tenant, Tenant shall be responsible for
any alterations, changes or improvements to the Premises which may be necessary
in order for the Premises and Tenant's use thereof to be in compliance with the
Americans with Disabilities Act of 1990 and its state and local counterparts or
equivalents (the "Disabilities Act") during the term of this Lease. To the best
of Landlord's knowledge, but without any current investigation, the Common Areas
currently comply in all material respects with the Disabilities Act (subject,
however, to Landlord's right to challenge in court or through administrative
proceedings any regulations or rules implemented with respect to the
Disabilities Act).

         7.07 For the purposes of this Lease, the term "Hazardous Materials"
shall mean, collectively, (i) any biological materials, chemicals, materials,
substances or wastes which are now or hereafter become defined as or included in
the definition of "hazardous substances", "hazardous wastes", "hazardous
materials", "extremely hazardous wastes", "restricted hazardous wastes", "toxic
substances", "toxic pollutants", or words of similar import, under any
applicable Environmental Law (as defined below) and (ii) any petroleum or
petroleum products and asbestos in any form that is or could become friable.

         7.08 For the purposes of this Lease, the term "Environmental Laws"
shall mean all federal, state, and local laws, statutes, ordinances,
regulations, criteria, guidelines and rules of common law now or hereafter in
effect, and in each case as amended, and any judicial or administrative
interpretation thereof, including, without limitation, laws and regulations
relating to emissions, discharges, releases or threatened releases or Hazardous
Materials or otherwise related to the manufacture, processing, distribution,
use, treatment, storage, disposal, transport or handling of Hazardous Materials.

                                       7
<PAGE>

Environmental Laws include but are not limited to the Comprehensive
Environmental Response, Compensation, and Liability Act of 1980, as amended; the
Resource Conservation and Recovery Act, as amended; the Clean Air Act, as
amended; the Clean Water Act, as amended; and their state and local counterparts
or equivalents.

         7.09 Tenant shall not (either with or without negligence) cause or
permit the escape, disposal or release of any Hazardous Materials. Tenant shall
not allow the storage or use of such Hazardous Materials on the Premises or the
Project in any manner prohibited by the Environmental Laws or by the highest
standards prevailing in the industry for the storage and use of such Hazardous
Materials, nor allow to be brought into the Premises or the Project any such
Hazardous Materials except to use in the ordinary course of Tenant's business,
and then only after written notice is given to Landlord of the identity of such
Hazardous Materials and Landlord consents in writing to the use of such
materials. Landlord shall have the right at any times during the term of this
Lease to perform assessments of the environmental condition of the Premises and
of Tenant's compliance with this Section 7.09. In connection with any such
assessment, Landlord shall have the right to enter and inspect the Premises and
perform tests (including physically invasive tests), provided such tests are
performed in a manner that minimizes disruption to Tenant. Tenant will cooperate
with Landlord in connection with any such assessment by, among other things,
responding to inquires and providing relevant documentation and records. Tenant
will accept custody and arrange for the disposal of any Hazardous Materials that
are required to be disposed of as a result of those tests. Landlord shall have
no liability or responsibility to Tenant with respect to any such assessment or
test or with respect to results of any such assessment or test. If any lender or
governmental agency shall ever require testing to ascertain whether or not there
has been any release of Hazardous Materials, then the reasonable costs thereof
shall be reimbursed by Tenant to Landlord upon demand as additional charges if
such requirement applies to the Premises or Tenant's activities on the Project.
If any inspection indicates any (i) non-compliance with any Environmental Law or
the highest standards prevailing in the industry for the storage and use of
Hazardous Materials; (ii) damage; or (iii) contamination, Tenant shall, at its
cost and expense, remedy such non-compliance, damage or contamination. In
addition, Tenant shall execute affidavits, representations and the like from
time to time at Landlord's request concerning Tenant's best knowledge and belief
regarding the presence of Hazardous Materials on the Premises. Irrespective of
whether Landlord elects to inspect the Premises, if Hazardous Materials are
found on or about the Premises, Landlord shall have no responsibility, liability
or obligation whatsoever with respect to the existence, removal or
transportation of the Hazardous Material or the restoration and remediation of
the Premises. Tenant's obligations under this paragraph with respect to any
environmental condition shall not be applicable to the extent that such
environmental condition (a) exists prior to the commencement of the initial term
of the Lease, or (b) results from (i) the actions or omission of Landlord either
before the commencement of this Lease, during the term hereof or after the
termination of this Lease, or (ii) the actions or omissions of any preceding or
succeeding tenant or owner of the Premises, Further, Landlord shall have the
right to require Tenant to immediately terminate the conduct of any activity in
violation of the Environmental Law, the highest standards prevailing in the
industry for the storage and use of Hazardous Materials or, if none exist, the
standards determined by Landlord.

         7.10 Tenant further agrees that it will not, by either action or
inaction, invite or otherwise cause agents or representatives of any federal,
state or local governmental agency to enter onto the Premises or the Project
and/or investigate the Premises or the Project. This agreement does not allow
Tenant to obstruct any such entry or investigation and the mere fact of a
regulatory agency entry or investigation without Tenant's involvement either by
action or inaction shall not be deemed a breach of this lease. Nothing set forth
in this paragraph shall prohibit Tenant from reporting any fact or condition
which Tenant has been advised it has a legal obligation to report provided
Tenant first notifies Landlord of such fact or condition and Tenant's intention
to report the fact or condition.

         7.11 Tenant shall indemnify, hold harmless and defend Landlord, its
licensees, servants, agents, employees and contractors from any loss, damage,
claim, liability or expense (including reasonable attorney's fees) arising out
of the failure of the Premises or Tenant's use thereof to be in compliance with
Disabilities Act. Tenant shall not be required to indemnify, hold harmless or
defend Landlord for the failure, if any, of the common areas (including the
parking areas, ramps and walkways) to comply with the Disabilities Act. Tenant
shall indemnify, hold harmless and defend Landlord, its licensees, servants,
agents, employees and contractors for any loss, damage, claim, liability or
expense (including reasonable attorney's fees) arising out of any violation of
any Environmental Law(s) by Tenant or its responsible parties (as described in
Section 7.09 above) on the Premises or the Project which occurs after the date
hereof. Tenant shall notify Landlord as soon as possible after Tenant learns of
the existence of or potential for any such loss, damage, claim, liability or
expense arising out of any violation or suspected violation of any Environmental
Law(s) or the Disabilities Act. In the event Tenant refuses to address such
violation or suspected violation within five (5) days of such notice from
Landlord, and, thereafter, to investigate such violation or suspected violation,
and promptly commence and diligently pursue any action required to address such
violation or suspected violation, Landlord shall have the right, in addition to
every other right and remedy it may have hereunder, to terminate this Lease by
giving ten (10) days prior written notice thereof to Tenant, and upon the
expiration of such ten (10) days, this Lease

                                       8
<PAGE>

shall terminate. The covenants set forth herein shall survive the expiration or
earlier termination of this Lease.

                                   SECTION 8.

                                    INSURANCE

         8.01 Commencing on the Commencement Date, Tenant shall, during the Term
of this Lease, maintain in full force and effect policies of commercial general
liability insurance (including premises, operation, bodily injury, personal
injury, death, independent contractors, products and completed operations, broad
form contractual liability and broad form property damage coverage), in a
combined single limit amount of not less than Five Million Dollars ($5,000,000),
per occurrence (exclusive of defense costs), against all claims, demands or
actions with respect to damage, injury or death made by or on behalf of any
person or entity, arising from or relating to the conduct and operation of
Tenant's business in, on or about the Premises (which shall include Tenant's
signs, if any), or arising from or related to any act or omission of Tenant or
of Tenant's principals, officers, agents, contractors, servants, employees,
licensees and invitees. Whenever, in Landlord's reasonable judgment, good
business practice and changing conditions indicate a need for additional amounts
or different types of insurance coverage, Tenant shall, within ten (10) days
after Landlord's request, obtain such insurance coverage, at Tenant's sole cost
and expense.

         8.02 Commencing on the Commencement Date, Tenant shall obtain and
maintain policies of workers' compensation and employers' liability insurance
which shall provide for statutory workers' compensation benefits and employers'
liability limits of not less than that required by law.

         8.03 Commencing on the Commencement Date, Tenant shall obtain and
maintain insurance protecting and indemnifying Tenant against any and all damage
to or loss of any personal property, fixtures, leasehold improvements,
alterations, decorations, installations, repairs, additions, replacements or
other physical changes in or about the Premises, including but not limited to
the Tenant Improvements, and all claims and liabilities relating thereto, for
their full replacement value without deduction or depreciation. In addition, if
Tenant shall install or maintain one or more pressure vessels to serve Tenant's
operations on the Premises, Tenant shall, at Tenant's sole cost and expense,
obtain, maintain and keep in full force and effect appropriate boiler or other
insurance coverage therefore in an amount not less than One Million and No/100
Dollars ($1,000,000.00) (it being understood and agreed, however, that the
foregoing shall not be deemed a consent by Landlord to the installation and/or
maintenance of any such pressure vessels in the Premises, which installation
and/or maintenance shall at all times be subject to the prior written consent of
Landlord). All insurance policies required pursuant to this Paragraph 8.03 shall
be written on a so-called "all risk" form and shall be carried in sufficient
amount so as to avoid the imposition of any co-insurance penalty in the event of
a loss. Such insurance shall provide the broadest coverage then available,
including coverage for loss of profits or business income or reimbursement for
extra expense incurred as the result of damage or destruction to all or a part
of the Premises.

         8.04 All insurance policies which Tenant shall be required to maintain
pursuant to this Section 8 shall, in addition to any of the foregoing: be
written by insurers which have an A.M. Best & Company rating of "A", Class "X",
or better and who are authorized to write such business in the State of Michigan
and are otherwise satisfactory to Landlord; be written as "occurrence" policy;
be written as primary policy coverage and not contributing with or in excess of
any coverage which Landlord or any ground or building lessor may carry; name
Landlord, Teachers Insurance and Annuity Association and its subsidiaries, the
Manager, and Landlord's mortgagee and ground or building lessor, if any, as
additional insureds; be endorsed to provide that they shall not be cancelled,
failed to be renewed, diminished or materially altered for any reason except on
thirty (30) days prior written notice to Landlord and the other additional
insureds; and provide coverage to Landlord, Landlord's property management
company, and Landlord's mortgagee whether or not the event or occurrence giving
rise to the claim is alleged to have been caused in whole or in part by the acts
or negligence of Landlord, Landlord's property management company, or Landlord's
mortgagee. At Landlord's option, either the original policies or certified
duplicate copies of the original policies will be delivered by Tenant to
Landlord at least ten (10) days prior to their effective date thereof, together
with receipts evidencing payment of the premiums therefor. Tenant will deliver
certificates of renewal for such policies to Landlord not less than thirty (30)
days prior to the expiration dates thereof. No such policy shall contain a
deductible or self insured retention greater than $5,000.00 per claim, nor shall
any such policy be the subject of an indemnification or other arrangement by
which any insured is obligated to repay any insurer with respect to loss
occurring on the Premises.

         8.05 If Tenant fails to provide all or any of the insurance required by
this Section 8 or subsequently fails to maintain such insurance in accordance
with the requirements hereof, then after giving five (5) business days
written notice to Tenant, Landlord may (but will not be required to)

                                       9
<PAGE>

procure or renew such insurance to protect its own interests only, and any
amounts paid by Landlord for such insurance will be additional rental due and
payable on or before the next Rent Day, together with late charges and interest
as provided in Section 5 hereof. Landlord and Tenant agree that no insurance
acquired by Landlord pursuant hereto shall cover any interest or liability of
Tenant and any procurement by Landlord of any such insurance or the payment of
any such premiums shall not be deemed to waive or release the default of Tenant
with respect thereto.

                                   SECTION 9.

                        DAMAGE BY FIRE OR OTHER CASUALTY

         9.01 It is understood and agreed that if, during the Term hereof, the
Project and/or the Premises shall be damaged or destroyed in whole or in part by
fire or other casualty, without the fault or neglect of Tenant, Tenant's
servants, employees, agents, visitors, invitees or licensees, which damage is
covered by insurance carried pursuant to Section 8 above, unless Landlord elects
to terminate this Lease as provided in Paragraph 9.02 below, Landlord shall
cause the Project and/or the Premises to be repaired and restored to good,
tenantable condition with reasonable dispatch at its expense; provided, however,
Landlord shall not be obligated to expend for such repair or restoration an
amount in excess of insurance proceeds made available to Landlord for such
purpose, if any. Landlord's obligation hereunder shall be limited to repairing
or restoring the Project and/or the Premises to substantially the same condition
that existed prior to such damage or destruction.

         9.02 If (i) more than fifty (50%) percent of the floor area of the
Premises shall be damaged or destroyed, (ii) more than twenty-five (25%) percent
of the Project shall be damaged or destroyed, or (iii) any material damage or
destruction occurs to the Premises or the Project during the last twelve (12)
months of the Initial Term or Option Term, as the case may be, then Landlord may
elect to either terminate this Lease or repair and rebuild the Premises. In
order to terminate this lease pursuant to this Paragraph, Landlord must give
written notice to Tenant of its election to so terminate, such notice to be
given within ninety (90) days after the occurrence of damage or destruction
fitting the above description, and thereupon the term of this Lease shall expire
by lapse of time ten (10) days after such notice is given and Tenant shall
vacate the Premises and surrender the same to Landlord, without prejudice,
however, to Landlord's rights and remedies against Tenant under the Lease
provisions in effect prior to such termination, and any rent owing shall be paid
up to such date and any payments of rent made by Tenant which were on account of
any period subsequent to such date shall be returned to Tenant. Tenant
acknowledges that Landlord will not carry insurance on Tenant's furniture and/or
furnishings or any fixtures or equipment, improvements, or appurtenances
removable by Tenant and agrees that Landlord will not be obligated to repair any
damage thereto or replace the same.

         9.03 Tenant shall give immediate notice to Landlord in case of fire or
accident at the Premises. If Landlord repairs or restores the Premises as
provided in Paragraph 9.01 above, Tenant shall promptly repair or replace its
trade fixtures, furnishings, equipment, personal property and leasehold
improvements in a manner and to a condition equal to that existing prior to the
occurrence of such damage or destruction.

         9.04 If the casualty, or the repairing or rebuilding of the Premises
pursuant to Paragraphs 9.01 and 9.02 above shall render the Premises
untenantable, in whole or in part, a proportionate abatement of the rent due
hereunder shall be allowed from the date when the damage occurred until the date
Landlord completes the repairs on the Premises or, in the event Landlord elects
to terminate this Lease, until the date of termination. Such abatement shall be
computed on the basis of the ratio of the floor area of the Premises rendered
untenantable to the entire floor area of the Premises.

         9.05 Tenant shall not entrust any property to any employee, contractor,
licensee, or invitee of Landlord. Any person to whom any property is entrusted
by or on behalf of Tenant in violation of foregoing prohibition shall be deemed
to be acting as Tenant's agent with respect to such property and neither
Landlord nor its agents shall be liable for any damage to property of Tenant or
of others entrusted to employees of the Project, nor shall Landlord or its
agents be liable for any such damage caused by other tenants or persons in, upon
or about the Project or caused by operations or construction of any private,
public or quasi-public work.

         9.06 Within fifteen (15) days of any damage or destruction to the
Premises described in Section 9.01, Tenant shall provide written notice to
Landlord requesting an estimate of the time required to substantially repair or
restore the Premises. If Tenant fails to request said estimate by providing
written notice to Landlord within such time period, Tenant's right to terminate
this Lease under this paragraph shall be deemed waived. Within a reasonable time
of receipt of Tenant's notice, Landlord shall provide a written notice to Tenant
(the "Landlord Casualty Repair Estimate Notice") indicating the scheduled
completion date to repair or restore the Premises "ready for occupancy" as
defined in Section 2.04 to substantially the same condition it existed
immediately prior to the damage or destruction. If the scheduled completion date
in the Landlord Casualty Repair Estimate Notice is more than two-hundred

                                       10

<PAGE>

seventy (270) days after the date of the damage or destruction (the "Restoration
Period"), then Tenant may elect to terminate this Lease. In order to terminate
this Lease pursuant to this paragraph, Tenant must give written notice to
Landlord of its election to so terminate, such notice (the "Tenant Casualty
Termination Notice") shall be given within fifteen (15) days of the date the
Landlord Casualty Repair Estimate Notice and thereupon the Term of this Lease
shall expire by lapse of time thirty (30) days after Tenant Casualty Termination
Notice is given and Tenant shall vacate the Premises and surrender the same to
Landlord, without prejudice, however, to Landlord's rights and remedies against
Tenant under the Lease provisions in effect prior to such termination, and any
rent owing shall be paid up to such date and any payments of rent made by Tenant
which were on account of any period subsequent to such date shall be returned to
Tenant.

                                   SECTION 10.

                      REPAIRS, RENOVATIONS AND ALTERATIONS

         10.01 Tenant shall, at Tenant's sole expense, keep the interior of the
Premises and the fixtures therein in good condition, reasonable wear and tear
excepted, and will also repair all damage or injury to the Premises and fixtures
resulting from the carelessness, omission, neglect or other action or inaction
of Tenant, its servants, employees, agents, visitors, invitees or licensees.
Such damage shall be promptly repaired or damaged items replaced by Tenant, at
its sole expense, to the satisfaction of Landlord. If Tenant fails to make such
repairs or replacements, Landlord may do so and the cost thereof shall become
collectible as additional rent hereunder and shall be paid by Tenant within ten
(10) days after presentation of statement therefor. Landlord shall maintain, and
shall make all necessary repairs and replacements to, the Building, the heating,
air conditioning and electrical systems located therein, and the Common Areas,
provided that at Landlord's option, (i) Tenant shall make all repairs and
replacements arising from its act, neglect or default and that of its agents,
servants, employees, invitees and licensees, or (ii) Landlord may make such
repairs and replacements and the costs thereof shall become collectable as
additional rent hereunder and shall be paid by Tenant within five (5) days after
presentation of a statement therefore. Tenant shall keep and maintain the
Premises in a clean, sanitary and safe condition, and shall keep and maintain
the interior of the Premises in full compliance with the laws of the United
States and State of Michigan, all directions, rules and regulations of any
health officer, fire marshal, building inspector, or other proper official of
any governmental agency having jurisdiction over the Premises, and the
requirements of Landlord's mortgagee, all at Tenant's full cost and expense, and
Tenant shall comply with all requirements of law, ordinance and regulation
affecting the Premises. Tenant shall make all non-structural repairs to the
Premises as and when needed to preserve them in good order and condition. All
the aforesaid repairs shall be of quality or class equal to the original
construction. Tenant shall give Landlord prompt written notice of any defective
condition in any plumbing, heating system or electrical lines located in,
servicing or passing through the Premises and following such notice, Landlord
shall remedy the condition with due diligence but at the expense of Tenant if
repairs are necessitated by damage or injury attributable to Tenant, Tenant's
servants, agents, employees, invitees or licensees. There shall be no allowance
to Tenant for diminutions of rental value and no liability on the part of
Landlord by reason of inconvenience, annoyance or injury to business arising
from Landlord, Tenant, or others making or failing to make any repairs,
alterations, additions, or improvements in or to any portion of the Building or
the Premises or in and to the fixtures, appurtenances or equipment thereof. The
provisions of this Section 10 with respect to the making of repairs shall not
apply in the case of fire or other casualty which are dealt with in Section 9
hereof.

         10.02 Tenant shall not have the right to make any renovations,
alterations, additions or improvements to the Premises which impact or modify
the structural elements of the Project without first obtaining Landlord's prior
written consent, which consent may be granted or withheld in Landlord's sole and
absolute discretion. Tenant shall not have the right to make any renovations,
alterations, additions or improvements to the Premises which impact or modify on
the plumbing, electrical, mechanical or fire and safety systems of the Building
without obtaining Landlord's prior written consent, which consent shall not be
unreasonably withheld. All plans and specifications for such renovations,
alterations, additions or improvements shall be approved by Landlord prior to
commencement of any work. Landlord's approval of the plans, specifications and
working drawings for Tenant's alterations shall create no responsibility or
liability on the part of Landlord for their completeness, design sufficiency, or
compliance with laws, rules and regulations of governmental agencies or
authorities, including but not limited to the Americans with Disabilities Act,
as amended. All renovations, alterations, additions or improvements made by
Tenant upon the Premises, except for movable office furniture and movable trade
fixtures installed at the expense of Tenant, shall be and shall remain the
property of Landlord, and shall be surrendered with the Premises at the
termination of this Lease, without molestation or injury. In addition, Landlord
may designate by written notice to Tenant at the time of installation the
alterations, additions, improvements and fixtures made by or for Tenant, which
shall be removed by Tenant at the expiration or termination of the Lease and
Tenant shall promptly remove the same and repair any damage to the Premises
caused by such removal.

                                       11

<PAGE>

         10.03 Tenant agrees that all renovations, alterations, additions and
improvements made by it pursuant to Paragraph 10.02, notwithstanding Landlord's
approval thereof, shall be done in a good and workmanlike manner and in
conformity with all guidelines provided by Landlord and all laws, ordinances and
regulations of all public authorities having jurisdiction, that materials of
good quality shall be employed therein, that the structure of the Premises shall
not be impaired thereby, that the work shall be carried out and completed in an
orderly, clean and safe manner, and that, while the work is being performed,
Tenant shall maintain builder's risk insurance coverage with Landlord as a named
insured, which insurance coverage shall meet the criteria set forth in Section
8.

                                   SECTION 11.

                                      LIENS

         11.01 Tenant will keep the Premises free of liens of any sort and will
hold Landlord harmless from any liens which may be placed on the Premises except
those attributable to debts incurred by Landlord. In the event a construction or
other lien shall be filed against the Building, the Premises or Tenant's
interest therein as a result of any work undertaken by Tenant or its employees,
agents, contractors or subcontractors, or as a result of any repairs or
alterations made by or any other act of Tenant or its employees, agents,
contractors or subcontractors, Tenant shall, within two (2) days after receiving
notice of such lien, discharge such lien either by payment of the indebtedness
due the lien claimant or by filing a bond (as provided by statute) as security
for the discharge of such lien. In the event Tenant shall fail to discharge such
lien, Landlord shall have the right to procure such discharge by filing such
bond, and Tenant shall pay the cost of such bond to Landlord as additional rent
upon the next Rent Day in accordance with Section 5 hereof.

                                   SECTION 12.

                                 EMINENT DOMAIN

         12.01 If all of the Premises are condemned or taken in any manner
(including without limitation any conveyance in lieu thereof) for any public or
quasi-public use, the term of this Lease shall cease and terminate as of the
date title is vested in the condemning authority. If (i) more than fifty (50%)
percent of the floor area of the Premises shall be condemned or taken in any
manner, or (ii) more than twenty-five (25%) percent of the Building shall be
condemned or taken, or (iii) any material condemnation or taking occurs during
the last twelve (12) months of the Initial Term or Option Term, as the case may
be, or (iv) such a portion of the parking area on the Land is so condemned or
taken that the number of parking spaces remaining are less than the number
required by applicable zoning laws or other building code for the Building, then
Landlord may elect to terminate this Lease. In order to terminate this Lease
pursuant to this Paragraph, Landlord must give Tenant written notice of its
election to so terminate, such notice to be given not later than ninety (90)
days after the completion of such condemnation or taking, and thereupon the term
of this Lease shall expire on the date set forth in such notice, and Tenant
shall vacate the Premises and surrender the same to Landlord, without prejudice,
however, to Landlord's rights and remedies against Tenant under the Lease
provisions in effect prior to such termination, and any rent owing shall be paid
up to such date and any payments of rent made by Tenant which were on account of
any period subsequent to such date shall be returned to Tenant.

         12.02 If this Lease is not terminated following such a condemnation or
taking, Landlord, as soon as reasonably practicable after such condemnation or
taking and the determination and payment of Landlord's award on account thereof,
shall expend as much as may be necessary of the net amount which is awarded to
Landlord and released by Landlord's mortgagee, if any, in restoring, to the
extent originally constructed by Landlord (consistent, however, with zoning laws
and building codes then in existence), so much of the Building as was originally
constructed by Landlord to an architectural unit as nearly like its condition
prior to such taking as shall be practicable; provided, however, Landlord shall
not be obligated to expend for such restoration an amount in excess of
condemnation proceeds made available to Landlord, if any. Landlord's obligation
hereunder shall be limited to restoring the Building and/or the Premises to
substantially the same condition that existed prior to such condemnation or
taking.

         12.03 If this Lease is not terminated pursuant to Paragraph 12.01, the
Base Rent and other sums payable by Tenant hereunder, as adjusted as provided
herein, shall be reduced in proportion to the reduction in area of the Premises
by reason of the condemnation or taking. If this Lease is terminated pursuant to
Paragraph 12.01, the minimum net rental and other charges which are the
obligation of Tenant hereunder shall be apportioned and prorated accordingly as
of the date of termination.

         12.04 The whole of any award or compensation for any portion of the
Premises taken, condemned or conveyed in lieu of taking or condemnation,
including the value of Tenant's leasehold interest under the Lease, shall be
solely the property of and payable to Landlord. Nothing herein contained shall
be deemed to preclude Tenant from seeking, at its own cost and expense, an award
from the condemning authority for loss of its business, the value of any trade
fixtures or other personal property

                                       12
<PAGE>

of Tenant in the Premises or moving expenses, provided that the award for such
claim or claims shall not be in diminution of the award made to Landlord.

                                   SECTION 13.

                            ASSIGNMENT OR SUBLETTING

         13.01 Tenant agrees not to assign or in any manner transfer this Lease
or any interest in this Lease without the prior written consent of Landlord,
which consent shall not be unreasonably withheld or delayed, and not to sublet
the Premises or any part of the Premises or to allow anyone to use or to come
in, through or under the Premises without Landlord's consent, which consent
shall not be unreasonably withheld or delayed. Any attempted subletting or
assignment without Landlord's consent shall be voidable in Landlord's sole
discretion and, at Landlord's option, shall grant Landlord the right to
terminate this Lease or to exercise any of the other rights or remedies it may
have hereunder. If consented to, no assignment or subletting shall be binding
upon Landlord unless the sublessee or assignee shall deliver to Landlord an
instrument (in recordable form, if Landlord so requests) containing an agreement
of assumption of all of Tenant's obligations under this Lease. In no event may
Tenant assign, sublet or otherwise transfer this Lease or any interest in this
Lease at any time while an Event of Default exists hereunder. Landlord may, in
its sole discretion, refuse to give its consent to any proposed subletting or
assignment or exercise its other rights hereunder for any reason, including, but
not limited to, the financial condition, creditworthiness or business reputation
of the proposed sublessee or assignee, the prevailing market or quoted rental
rates for space in the Building or other comparable buildings, and the proposed
use of the Premises by, or business of, the proposed sublessee or assignee. One
consent by Landlord to a subletting or assignment will not be deemed a consent
to any subsequent assignment, subletting, occupation or use by any other person.
Neither the consent to any assignment or subletting nor the acceptance of rent
from an assignee, subtenant or occupant will constitute a release of Tenant from
the further performance of the obligations of Tenant contained in this Lease. A
dissolution, merger, consolidation, or other reorganization of Tenant and the
issuance or transfer of twenty (20%) percent or more of the voting capital of
Tenant to persons other than shareholders as of the beginning of such period
within any twelve (12) month period, shall each be deemed to be an assignment of
this Lease, and as such, prohibited without Landlord's prior written consent.
Notwithstanding anything in this paragraph to the contrary, Landlord shall allow
the occupancy of the Premises by Tenant's parent company or a subsidiary or an
affiliate which is wholly owned by Tenant (the "Related Entity"), or the
assignment of this Lease or the subletting of all or a portion of the Premises
to a Related Entity provided that: (i) Tenant shall give written notice to
Landlord at least sixty (60) days prior to said proposed occupancy, assignment
or subletting setting forth the terms thereof together with such financial and
other information Landlord may request; and (ii) any such occupancy, assignment
or subletting shall not constitute a release of Tenant from the further
performance of the obligations of Tenant contained in this Lease; and (iii) any
such occupancy, assignment or subletting shall be subject to Sections 13.03 and
13.04.

         13.02 In the event Tenant desires to sublet all or a portion of the
Premises or assign this Lease, Tenant shall give notice to Landlord setting
forth the terms of the proposed subletting or assignment together with such
financial and other information Landlord may reasonably request. Landlord shall
have the right, exercisable by written notice to Tenant within sixty (60) days
after receipt of Tenant's notice, (i) to consent or refuse to consent thereto in
accordance with Paragraph 13.01 above, or (ii) to terminate this Lease which
termination may, in Landlord's sole discretion, be conditioned upon Landlord and
the proposed subtenant/assignee entering into a new Lease. However, in the event
Landlord desires to elect to terminate this Lease, it shall first notify Tenant
of its desire whereupon Tenant may withdraw the request within ten (10) days
after Landlord's notice by the delivery of written withdrawal thereof to
Landlord whereupon Landlord shall withdraw its recapture option and Tenant shall
remain fully obligated under this Lease.

         13.03 Upon the occurrence of an Event of Default, as defined under
Section 18, if all or any part of the Premises are then sublet or assigned,
Landlord, in addition to any other remedies provided by this Lease or by law,
may, at its option, collect directly from the sublessee or assignee all rent
becoming due to Landlord by reason of the subletting or assignment. Any
collection by Landlord from the sublessee or assignee shall not be construed to
constitute a waiver or release of Tenant from the further performance of its
obligations under this Lease or the making of a new Lease with such sublessee or
assignee.

         13.04 In the event Tenant shall sublet all or a portion of the Premises
or assign this Lease, all of the sums of money or other economic consideration
received by Tenant or its affiliates, directly or indirectly, as a result of
such subletting or assignment, whether denominated as rent or otherwise, which
exceed in the aggregate the total sums which Tenant is obligated to pay Landlord
under this Lease (prorated to reflect obligations allocable to that portion of
the Premises subject to such sublease) shall be payable to Landlord as
additional rent under this Lease without effecting or reducing any other
obligation of Tenant hereunder.

                                   SECTION 14.

                             INSPECTION OF PREMISES

         14.01 Tenant agrees to permit Landlord to enter the Premises for the
purpose of inspecting the same and to show same to prospective purchasers,
tenants or mortgagees of the Project, and to make such repairs, alterations,
improvements or additions as Landlord may deem necessary or desirable, and
Landlord shall be allowed to take all material into and upon the Premises that
may be required therefor without the same constituting an eviction of Tenant in
whole or in part and the rent reserved shall in no way abate while said repairs,
alterations, improvements, or additions are being made, by reason of loss or
interruption of business of Tenant, or otherwise. Landlord will give Tenant
reasonable notice prior to an entry by Landlord pursuant to this Section 14.01,
except in the case of emergencies in which event no notice need be given.
Landlord shall use reasonable efforts not to materially disrupt or interfere
with the conduct of Tenant's business during such entry and Tenant may accompany
Landlord while in the Premises.

                                   SECTION 15.

                             FIXTURES AND EQUIPMENT

         15.01 All fixtures and equipment paid for by Landlord and all fixtures
and equipment which may be paid for and placed on the Premises by Tenant from
time to time but which are so incorporated and affixed to Premises that their
removal would involve damage or structural change to Premises will be and remain
the property of Landlord.

         15.02 All tenant furnishings, office equipment and tenant fixtures
(other than those specified in Sections 10.02 and 15.01), which are paid for and
placed on the Premises by Tenant from time to time (other than those which are
replacements for fixtures originally paid for by Landlord) will remain the
property of Tenant.

                                   SECTION 16.

                                  PARKING AREAS

         16.01 Tenant and its agents, employees, customers, licensees and
invitees shall have the non-exclusive right to use in common with Landlord and
all other tenants and occupants of the Building and their respective agents,
employees, customers, licensees and invitees, the Common Area parking and
loading dock facilities, if any, on the Land, and all driveways, entrances and
exits located within the Project necessary to provide a means of ingress and
egress to and from the Premises. Such use of parking facilities shall be subject
to, and consistent with, the Rules and Regulations of the Project (as set forth
in Exhibit B), together with such reasonable modifications and additions as may
be made thereto during the term of this Lease. Landlord shall designate the
number of parking spaces set forth in Paragraph 1.01(i) in the parking lot of
the Project for the exclusive use of Tenant (the "Tenant's Designated Parking
Spaces"). Tenant shall pay Landlord, as additional rent on each Rent Day, an
amount set forth in Section 1.01(i). Such sums may be increased by Landlord from
time to time by the delivery of thirty (30) days prior written notice to Tenant.
Within thirty (30) days of receipt of such notification, Tenant may: (i) accept
such increase; or (ii) reject such increase for all or any of its exclusive
spaces, in which event Tenant's exclusive parking rights for such spaces shall
terminate. If Tenant accepts such increase or fails to reject such increase
within the thirty (30) day period, then commencing with the next Rent Day
following Landlord's notice, the amount of additional rent payable hereunder
shall be increased accordingly. Notwithstanding anything contained herein to the
contrary, Landlord shall have the right to relocate Tenant's Designated Parking
Spaces within the parking lot of the Project, and Landlord shall have the right
to designate other parking spaces in the parking lot for the exclusive use of
others. Tenant agrees to be bound by parking regulations in effect at the
Project, together with reasonable modifications or additions as may be necessary
during the term of this Lease, as more fully described in Exhibit "B", attached
hereto and made part hereof. Landlord shall use reasonable efforts to enforce
said rules and regulations against other tenants if the violation of such rules
and regulations interferes with the operation of Tenant's business in the
Premises.

                                   SECTION 17.

                                NOTICE OR DEMANDS

         17.01 All bills, notices, requests, statements, communications, or
demands (collectively, "notices or demands") to or upon Landlord or Tenant
desired or required to be given under any of the provisions hereof must be in
writing. Any such notices or demands from Landlord to Tenant will be deemed to
have been duly and sufficiently given if a copy thereof has been personally
delivered, mailed

                                       14
<PAGE>

by United States certified mail, return receipt requested, postage prepaid, or
sent via overnight courier service to Tenant at the address of the Premises or
at such other address as Tenant may have last furnished in writing to Landlord
for such purpose. Any such notices or demands from Tenant to Landlord will be
deemed to have been duly and sufficiently given if delivered to Landlord in the
same manner as provided above at the address set forth at the heading of this
Lease or at the address last furnished by written notice from Landlord to
Tenant. The effective date and the delivery date of such notice or demand will
be deemed to be the time when it is personally delivered, three (3) days after
it is mailed or the day after it is sent via overnight courier as herein
provided.

                                   SECTION 18.

                          BREACH; INSOLVENCY; RE-ENTRY

         18.01 Each of the following shall constitute an Event of Default
under this Lease: (i) Tenant's failure to pay rent or any other sum payable
hereunder for more than five (5) business days after written notice of such
failure has been delivered to Tenant (but if one notice has been given in any
twelve (12) month period, no further notice shall be required during such
twelve (12) month period); (ii) Tenant's failure to perform any of the
non-monetary terms, conditions or covenants of this Lease to be observed or
performed by Tenant for more than seven (7) business days after written
notice of such failure shall have been delivered to Tenant except in
connection with a breach which cannot be remedied or cured within said seven
(7) business day period, in which event the time of Tenant within which to
cure such breach shall be extended for such time as shall be necessary to
cure the same, but only if Tenant, within such seven (7) business day period,
shall have commenced and diligently proceeded to remedy or cure such breach;
(iii) if Tenant is named as the debtor in any bankruptcy proceeding, or
similar debtor proceeding, and any such proceeding, if involuntary, is not
dismissed or set aside within sixty (60) days from the date thereof; (iv) if
Tenant makes an assignment for the benefit of creditors or petitions for or
enters into an arrangement with creditors or if a receiver of any property of
Tenant in or upon the Premises is appointed in any action, suit or proceeding
by or against Tenant, or if Tenant shall admit to any creditor or to Landlord
that it is insolvent, or if the interest of Tenant in the Premises shall be
sold under execution or other legal process; or (v) if Tenant shall suffer
this Lease to be taken under any writ of execution. Upon the occurrence of
any Event of Default, Landlord, in addition to any other rights and remedies
it may have hereunder or by law, shall have the immediate right of re-entry,
and may remove all persons and property from the Premises and it shall have
the right to abandon or otherwise dispose of such property in any way it may
deem fit which is not in contravention of applicable law. In addition,
Landlord shall have the right, but not the obligation, to store all or some
of the property which may have been removed in a public warehouse or
elsewhere at the cost of, and for the account of, Tenant, all without service
of notice or resort to legal process and all without being deemed guilty of
trespass or becoming liable for any loss or damage which may be occasioned
thereby.

         18.02 In the event Landlord shall elect to re-enter the Premises in
accordance with Paragraph 18.01, or should Landlord take possession of Premises
pursuant to legal proceedings or pursuant to any notice provided by law,
Landlord may either terminate this Lease or may from time to time without
terminating this Lease, make such alterations and repairs as Landlord may deem
necessary in order to relet the Premises, and relet the Premises or any part
thereof for any such term or terms (which may be for a term extended beyond the
term of this Lease) and at such rental or rentals, and upon such other terms and
conditions as Landlord may deem advisable.

         18.03 Upon the reletting of the Premises in accordance with Paragraph
18.02, all rentals received by Landlord from such reletting shall be applied in
the following order of priority: (a) to the payment of any additional rent
payable as provided in Section 5 hereof, including interest and late charges;
(b) to the payment of any other indebtedness other than rent due hereunder from
Tenant to Landlord; (c) to the payment of the actual costs and expenses of
obtaining possession, restoring and repairing the Premises and the actual costs
and expenses of reletting, including brokerage and attorneys' fees; and (d) to
the payment of any rent and other sums due and unpaid under this Lease. The
remainder, if any, shall be held by Landlord and applied in payment of future
rent as the same may become due and payable hereunder. If the rental received
from such reletting during any month is less than that to be paid during that
month by Tenant hereunder, Tenant shall pay any such deficiency to Landlord
monthly. No such re-entry or taking possession of the Premises or any part
thereof by Landlord shall be construed as an election on its part to terminate
this Lease unless a written notice of such intention is given to Tenant or
unless the termination thereof is decreed by a court of competent jurisdiction.

         18.04 Notwithstanding any reletting of the Premises without termination
in accordance with Paragraph 18.02, Landlord may at any time after the
occurrence of any Event of Default, terminate this Lease and, in addition to any
other remedies Landlord may have, Landlord may recover from Tenant all damages
it may incur by reason of Tenant's breach, including, without limitation, the
reasonable cost of recovering and reletting the Premises and reasonable
attorneys' fees incidental thereto and the worth at

                                       15
<PAGE>

the time of the termination of the amount of rent and other charges payable
hereunder for the remainder of the Term, all of which amounts shall be
immediately due and payable by Tenant to Landlord.

         18.05 In case suit shall be brought or an attorney otherwise consulted,
for recovery of possession of the leased premises, for the recovery of rent or
any other amount due under the provisions of this Lease, or because of the
breach of any other covenant herein contained on the part of Tenant to be kept
and performed, or any other action against Tenant by Landlord, or because of any
claimed breach of this Lease by Landlord or any other action against Landlord by
Tenant, (and Landlord shall be the prevailing party), Tenant shall pay to
Landlord all expenses incurred therefor, including a reasonable attorneys' fee.
In addition, Landlord and Tenant hereby waive trial by jury in any action,
proceeding or counterclaim brought by Landlord or Tenant against the other on
any matter whatsoever arising out of or in any way connected with this Lease,
the relationship of Landlord to Tenant, the use or occupancy of the Premises by
Tenant or any person claiming through or under Tenant, any claim of injury or
damage, and any emergency or other statutory remedies; provided, however, the
foregoing waiver shall not apply to any action for personal injury or property
damage.

                                   SECTION 19.

                      SURRENDER OF PREMISES ON TERMINATION

         19.01 At the expiration (or earlier termination) of the Term hereof,
Tenant will surrender the Premises broom clean and in as good condition and
repair as they were at the time Tenant took possession, reasonable wear and tear
and damage by fire or other casualty not caused by Tenant, its agents or
employees excepted, and promptly upon surrender will deliver all keys and
building security cards for the Premises to Landlord at the place then fixed for
the payment of rent. At the expiration of the Lease term, Tenant will, at its
own cost and expense, repair or pay the cost of restoration with respect to any
damage to the Premises arising from the removal of any trade fixtures or similar
items. Tenant shall have no rights of removal as to property affixed or
otherwise placed on or in the Premises by or at the expense of Landlord, its
predecessors, successors or assigns. All costs and expenses incurred by Landlord
in connection with repairing or restoring the Premises to the condition called
for herein, together with the costs, if any, of removing any property of Tenant
together with any property designated by Landlord pursuant to Section 10.02,
left on the Premises, shall be paid by Tenant on demand. Tenant shall remove all
property of Tenant and make all repairs necessitated thereby at its own cost, as
directed by Landlord. Tenant's obligation to observe or perform this covenant
shall survive the expiration or other termination of the Term of this Lease.

                                   SECTION 20.

               PERFORMANCE BY LANDLORD OF THE COVENANTS OF TENANT

         20.01 If Tenant fails to pay any sum of money, other than Base Rent,
required to be paid hereunder or fails to perform any act on its part to be
performed hereunder, including, but not limited to, the performance of all
covenants pertaining to the condition and repair of the Premises pursuant to
Section 10 above, and if such failure shall not otherwise be cured within the
time, if any, provided herein, then upon two (2) days notice Landlord may (but
shall not be required to), without waiving or releasing Tenant from any of
Tenant's obligations, make any such payment or perform any such other act. All
sums so paid or incurred by Landlord and all incidental costs, including, but
not limited to, the cost of repair, maintenance or restoration of the Premises,
shall be deemed additional rental and, together with interest thereon computed
at the rate set forth in Section 5 hereof from the date of payment by Landlord
until the date of repayment by Tenant to Landlord, shall be payable to Landlord
on demand. On default in such payment, Landlord shall have the same remedies as
on default in payment of rent. The rights and remedies granted to Landlord under
this Section 20 shall be in addition to, and not in lieu of, all other remedies,
if any, available to Landlord under this Lease or otherwise, and nothing
contained herein shall be construed to limit such other remedies of Landlord
with respect to any matters covered herein.

                                   SECTION 21.

                      SUBORDINATION; ESTOPPEL CERTIFICATES

         21.01 This Lease is subject and subordinate to all ground leases,
underlying leases, and mortgages, if any, now or hereafter made, which may now
or hereafter affect the Project and to all

                                       16
<PAGE>

renewals, modifications, consolidations, replacements and extensions of any such
ground leases, underlying leases and mortgages. This clause shall be
self-operative and no further instrument of subordination shall be necessary.
Notwithstanding the foregoing, Landlord reserves the right to declare this Lease
prior to the lien of any ground lease, underlying lease, or mortgage now or
hereinafter placed upon the real property of which the Premises are a part by
recording a written notice of such priority with the register of deeds. Tenant
covenants and agrees to execute and deliver, within ten (10) days after
requested by Landlord, such further instrument or instruments subordinating this
Lease (or declaring the Lease prior and superior) to any lease or proposed lease
or to the lien of any such mortgage or mortgages as shall reasonably be desired
by Landlord, any lessor or proposed lessor, and any mortgagees or proposed
mortgagees.

         21.02 In the event any proceedings are brought for foreclosure of, or
in the event of the conveyance by deed in lieu of foreclosure of, or in the
event of the exercise of the power of sale under, any mortgage made by Landlord
covering the Premises, Tenant hereby attorns to the new owner, and covenants and
agrees to execute any instrument in writing reasonably satisfactory to the new
owner, whereby Tenant attorns to such successor in interest and recognizes such
successor as Landlord under this Lease.

         21.03 Tenant, within ten (10) business days after request (at any time
or times) by Landlord, will execute and deliver to Landlord an estoppel
certificate, in form reasonably acceptable to Landlord, certifying: (i) to the
Commencement Date and expiration date of the Term; (ii) that this Lease is
unmodified and in full force and effect, or is in full force and effect as
modified, stating the modifications; (iii) that Tenant does not claim that
Landlord is in default in any way, or listing any such claimed defaults and that
Tenant does not claim any rights of setoff, or listing such rights of setoff;
(iv) to the amount of monthly rent and other sums due hereunder as of the date
of the certificate, the date to which the rent has been paid in advance, and the
amount of any security deposit or prepaid rent; (v) that Tenant agrees to
provide any mortgagee of Landlord with notice of any default by Landlord
hereunder and give such mortgagee the opportunity to cure such default within
sixty (60) days of such mortgagee's receipt of notice of such default; and (vi)
such other matters as may be reasonably requested by Landlord. Any such
certificate may be relied upon by any prospective purchaser, mortgagee or lessor
of the Premises or any part thereof.

                                   SECTION 22.

                                 QUIET ENJOYMENT

         22.01 Landlord agrees that at all times when no Event of Default exists
under this Lease, Tenant's quiet and peaceable enjoyment of the Premises, in
accordance with and subject to the terms of this Lease, will not be disturbed or
interfered with by Landlord or any person claiming by, through, or under
Landlord.

                                   SECTION 23.

                                  HOLDING OVER

         23.01 If Tenant remains in possession of the Premises after the
expiration of this Lease without executing a new lease, Landlord shall have the
right to deem Tenant to be occupying the Premises as a tenant from month to
month and the Base Rent for each month will be two hundred percent (200%) of the
greater of: (a) the regular monthly installment of Base Rent payable for the
last month of the Term of this Lease; or (b) the then prevailing market rates of
rent for the Project determined by Landlord in its sole and absolute discretion.
This provision shall not preclude Landlord from terminating the lease or
recovering any and all damages Landlord may incur as a result of Tenant's
failure to timely deliver possession of the Premises to Landlord or from
exercising any other right or remedy it may have hereunder.

                                   SECTION 24.

                         REMEDIES NOT EXCLUSIVE; WAIVER

         24.01 Each and every of the rights, remedies and benefits of Landlord
provided by this Lease are cumulative, and are not exclusive of any other of
said rights, remedies and benefits, or of any other rights, remedies and
benefits allowed by law.

         24.02 The failure of Landlord to seek redress for violation of, or to
insist upon the strict performance of, any covenant or condition of this Lease
or of any of the rules or regulations set forth or hereafter adopted by
Landlord, shall not prevent a subsequent act which would have originally
constituted a violation from having all the force and effect of an original
violation. The receipt by Landlord of rent with knowledge of the breach of any
covenant of this Lease shall not be deemed a waiver of such breach and no
provision of this Lease shall be deemed to have been waived by Landlord unless
such waiver be in writing signed by Landlord. One or more waivers of any
covenant or condition by either party shall not be

                                       17
<PAGE>

construed as a waiver of a further or subsequent breach of the same covenant or
condition, and the consent or approval by Landlord to or of any act by Tenant
requiring Landlord's consent or approval will not be deemed to waive or render
unnecessary Landlord's consent or approval to or of any subsequent similar act
by Tenant. No payment by Tenant or receipt by Landlord of a lesser amount than
the monthly rental herein stipulated shall be deemed to be other than on account
of the earliest stipulated rent, nor shall any endorsement or statement on any
check or any letter accompanying any check or payment as rent be deemed an
accord and satisfaction, and Landlord shall accept such check or payment without
prejudice to Landlord's right to recover the balance of such rent or pursue any
other remedy provided in this Lease.

                                  SECTION 25.

                              WAIVER OF SUBROGATION

         25.01 Anything to the contrary in this Lease notwithstanding to the
extent not prohibited by or violative of any policy of fire and extended
coverage or all-risk property insurance issued to Tenant, neither Landlord, nor
its officers, directors, employees, agents or invitees, shall be liable to
Tenant or to any insurance company (by way of subrogation or otherwise) insuring
Tenant for any loss or damage to any building, structure or other tangible
property, when such loss is caused by any of the perils which are or could be
insured against under this all-risk property policies required hereunder, or
losses under workers' compensation laws and benefits, even though such loss or
damage might have been occasioned by the negligence of Landlord, its agents or
employees. Tenant represents that its current insurance policies allow such
waiver and will immediately notify Landlord if such waiver becomes unavailable
or is not obtainable. In the absence of such notification, Tenant will be deemed
to have obtained such waiver of subrogation.

                                   SECTION 26.

                             RIGHT TO SHOW PREMISES

         26.01 Upon reasonable notice Landlord may show the Premises to
prospective tenants and brokers, and may display signs about the Project and
elsewhere advertising the availability of the Premises. Landlord shall use
reasonable efforts not to materially disrupt or interfere with the conduct of
Tenant's business during such entry and Tenant may accompany Landlord while in
the Premises.

                                   SECTION 27.

                                 INDEMNIFICATION

         27.01 Tenant, its successors and assigns shall indemnify and hold
harmless Landlord and all superior lessors or superior mortgagees and its and
their respective partners, directors, officers, agents and employees from and
against any and all third-party claims arising from or in connection with: (i)
the conduct or management of the Premises or of any business therein, or any
work or thing whatsoever done, or any condition created (even if due to
Landlord's negligence or breach of this Lease, except Landlord gross negligence
and/or Landlord willful and malicious acts) in or about the Premises, during the
term of this Lease; (ii) any act, omission or negligence of Tenant or any of its
subtenants or licensees or its or their partners, directors, officers, agents,
employees, invitees or contractors; (iii) any accident, injury or damage
whatever (even if caused by Landlord's negligence except Landlord gross
negligence and/or Landlord willful and malicious acts) occurring in, at or upon
the Premises; and (iv) any breach or default by Tenant in the full and prompt
payment and performance of Tenant's obligations under this Lease; together with
all costs, expenses and liabilities incurred or in connection with each such
claim or action or proceeding brought thereon, including, without limitation,
all attorneys' fees and expenses. If any case any action or proceeding is
brought against Landlord or any superior lessor or superior mortgagee or its or
their partners, directors, officers, agents or employees and such claim is a
claim for which Tenant is obligated to indemnify Landlord pursuant to this
Paragraph 27, Tenant upon notice from Landlord or such superior lessor or
superior mortgagee, shall resist and defend such action or proceeding (by
counsel reasonably satisfactory to Landlord). The obligation of Tenant under
this Paragraph 27 shall survive termination of this Lease.

                                   SECTION 28.

                  DEFINITION OF LANDLORD; LANDLORD'S LIABILITY

         28.01 The term "Landlord" as used in this Lease so far as covenants,
agreements, stipulations or obligations on the part of Landlord are concerned is
limited to mean and include only the owner or

                                       18
<PAGE>

owners of the Premises at the time in question, and in the event of any transfer
or transfers of the title to such fee Landlord herein named (and in case of any
subsequent transfers or conveyances the then grantor) will automatically be
freed and relieved from and after the date of such transfer or conveyance of all
personal liability for the performance of any covenants or obligations on the
part of Landlord contained in this Lease thereafter to be performed.

         28.02 This Lease and the obligation of Tenant to pay rent hereunder and
perform all of the other covenants and agreements hereunder on the part of
Tenant to be performed shall in no way be affected, impaired or excused because
Landlord is unable to fulfill any of its obligations under this Lease or is
unable to supply or is delayed in supplying any service expressly or implied to
be supplied or is unable to make, or is delayed in making any repairs,
additions, alterations or decorations or is unable to supply or is delayed in
supplying any equipment or fixtures if Landlord is prevented or delayed from so
doing by reasons of shortages of materials, acts of God, governmental
restrictions, strike or labor troubles or any cause beyond Landlord's reasonable
control including, but not limited to, government preemption in connection with
a national emergency or by reason of any rule, order or regulation of any
department or subdivision thereof of any government agency or by reason of the
conditions of supply and demand which have been or are affected by war or other
emergency.

                                   SECTION 29.

                     SECURITY DEPOSIT AND SECURITY INTEREST

         29.01 Upon execution hereof, Tenant shall deliver to Landlord a
Letter of Credit in the amount set forth in Section 1.01(j), above, and Exhibit
D, which Landlord is to retain as security for the faithful performance of all
the covenants, conditions and agreements of this Lease, but in no event shall
Landlord be obligated to apply the same upon rents or other charges in arrears
or upon damages for Tenant's failure to perform the said covenants, conditions,
and agreements; Landlord may so apply the security at its option, and Landlord's
right to the possession of the Premises for nonpayment of rent or for any other
reason shall not in any event be affected by reason of the fact that Landlord
holds this security. The said sum, if not applied toward the payment of rent in
arrears or toward the payment of damages suffered by Landlord by reason of
Tenant's breach of the covenants, conditions and agreements of this Lease, is to
be returned, without interest thereon, to Tenant when this Lease is terminated,
and fully performed by Tenant, according to these terms, and in no event is the
said security to be returned until Tenant has vacated the Premises and delivered
possession to Landlord.

         29.02 In the event that Landlord repossesses the Premises because of
Tenant's default or because of Tenant's failure to carry out the covenants,
conditions and agreements of this Lease, Landlord may apply the said security
upon all damages suffered to the date of said repossession and may retain the
said security to apply upon such damages as may be suffered or shall accrue
thereafter by reason of Tenant's default or breach. Landlord shall not be
obligated to keep the said security as a separate fund, but may mix the said
security with its own funds. In the event Landlord shall use any part of the
Security Deposit, Tenant shall, upon demand, deposit with Landlord the full
amount so used, in order that Landlord shall have the full Security Deposit on
hand at all times during the Term of this Lease. In the event of a sale or lease
of the Building and the transfer of the Security Deposit to the purchaser or
lessee, Landlord shall be released from all liability for the return of the
Security Deposit. Tenant shall have no legal power to assign or encumber the
Security Deposit herein described.

         29.03 To secure the faithful performance of all covenants, conditions
and agreements of this Lease to be performed and observed by Tenant and to
secure the payment of all rent and other sums which may be due Landlord under
this Lease, Tenant hereby grants Landlord a security interest in all property,
equipment, fixtures, chattels, inventory and general intangibles and the
proceeds thereof, whether now owned or hereafter acquired, which may at any time
be placed in or upon the Leased Premises or used or useable in connection with
Tenant's business (collectively the "Collateral"). Landlord agrees to execute
and deliver to Tenant after Tenant has executed such instrument subordinating
this Lease to the lien of the security interest in the form attached hereto as
Exhibit F. Upon the occurrence of an Event of Default, Landlord may exercise any
of its rights and remedies provided by the Uniform Commercial Code. The proceeds
of any such sale, after payment of Landlord's expenses, shall be applied to the
payment of Tenant's obligations hereunder and satisfaction of such Event of
Default. Enforcement of this security interest shall be in addition to and shall
not waive, alter, limit or affect in any manner any other remedies available to
Landlord. Tenant agrees that upon Landlord's request it shall execute and
deliver all such financing statements as may be necessary to perfect this
security interest. Provided no Event of Default exists under the terms of this
Lease, then within thirty (30) days after the expiration of the Term, Landlord
shall deliver all such termination statements as Tenant may reasonably request,
whereupon the security interest granted by this Section 29 shall terminate.

                                   SECTION 30.

                              RULES AND REGULATIONS

                                       19
<PAGE>

         30.01 Tenant shall faithfully abide by and observe the rules and
regulations for the Building, a copy of which is attached hereto as Exhibit B
and made a part hereof, and, after notice thereof, all reasonable additions
thereto and modifications thereof of uniform applicability from time to time
promulgated in writing by Landlord. Landlord shall use reasonable efforts to
enforce said rules and regulations against other tenants if the violation of
such rules and regulations interferes with the operation of Tenant's business in
the Premises.

                                   SECTION 31.

                              SIGNS AND ADVERTISING

         31.01 No signs, lighting, lettering, pictures, notices, advertisements,
shades, awnings or decorations will be displayed, used or installed by Tenant
except as approved in writing by Landlord. All such materials displayed in and
about the Premises will be such only as to advertise the business carried on
upon the Premises and Landlord will control the location, character and size
thereof. Tenant shall not cause or permit to be used any advertising materials
or methods which are reasonably objectionable to Landlord or to other tenants of
the Building, including without limiting the generality of the foregoing:
loudspeakers, mechanical or moving display devices, unusually bright or flashing
lights and similar devices the effect of which may be seen or heard from outside
the Premises. Tenant shall not solicit business, sell or display merchandise, or
distribute hand bills or other advertising matter in the parking area or other
Common Areas. Tenant shall receive at Landlord's expense, Building Standard
signage in the common corridor and elevator lobby.

                                   SECTION 32.

                                     GENERAL

         32.01 If, by reason of the occurrence of unavoidable delays due to acts
of God, governmental restrictions, strikes, labor disturbances, shortages of
materials or supplies or for any other cause or event beyond Landlord's
reasonable control, Landlord is unable to furnish or is delayed in furnishing
any service required by Landlord under the provisions of this Lease, or Landlord
is unable to perform or make or is delayed in performing or making any
installations, decorations, repairs, alterations, additions, or improvements,
required to be performed or made under this Lease, or is unable to fulfill or is
delayed in fulfilling any of Landlord's other obligations under this Lease, no
such inability or delay shall constitute an actual or constructive eviction in
whole or in part, or, except as otherwise expressly provided herein, entitle
Tenant to any abatement or diminution of rental or other charges due hereunder
or otherwise relieve Tenant from any of its obligations under this Lease, or
impose any liability upon Landlord or its agents by reason of inconvenience or
annoyance to Tenant, or injury to or interruption of Tenant's business, or
otherwise.

         32.02 This Lease is being entered into and executed in the State of
Michigan, and all questions with respect to the construction of this Agreement
and the rights and liabilities of the parties shall be determined in accordance
with the provisions of the laws of the State of Michigan.

         32.03 Many references in this Lease to persons, entities and items have
been generalized for ease of reading. Therefore, references to a single person,
entity or item will also mean more than one person, entity or thing whenever
such usage is appropriate (for example, "Tenant" may include, if appropriate, a
group of persons acting as a single entity, or as tenants-in-common). Similarly,
pronouns of any gender should be considered interchangeable with pronouns of
other genders.

         32.04 Section headings appearing in this Lease are for convenience
only. They do not define, limit or construe the contents of any paragraphs or
clauses contained herein.

         32.05 Landlord reserves the right should it become necessary to comply
with required laws and regulations, or to assure the health, safety and welfare
of Tenant or other occupants of the building to relocate Tenant in other
comparable space in the Building upon not less than sixty (60) days prior
written notice to Tenant. Landlord shall pay the cost of building and moving
Tenant to new space. Landlord shall use reasonable efforts to have the move take
place on a weekend and to be substantially completed by 8:00 a.m. Monday. If
Tenant does not wish to accept such relocation, Tenant may object thereto by
written

                                       20
<PAGE>

notice to Landlord within ten (10) days after the notice from Landlord.
In the event Tenant fails to object within such ten (10) day period, Tenant
shall be deemed to have accepted the relocation. In the event Tenant so objects,
Landlord may rescind the notice of intention to relocate Tenant or may reaffirm
said intention, in which event Tenant may terminate this Lease by written notice
to Landlord within five (5) days after the affirmation notice from Landlord. In
the event Tenant fails to notify Landlord of its termination within such five
(5) day period, it shall be deemed to have accepted the relocation. If Tenant
terminates this Lease pursuant this paragraph, Tenant must vacate the Premises
within thirty (30) days following Tenant's notice to Landlord of termination. As
to any relocation of Tenant to substitute space, such substitute space shall be
as suitable as the Premises for the conduct of Tenant's business, and such
substitute space and the Premises shall be concurrently available to Tenant as
necessary to provide for continuity in Tenant's business and to permit
relocation of Tenant's equipment and facilities with reasonable minimal
interruption in such business. The cost of relocation to be paid by Landlord
shall include the expense of the de-installation and installation of equipment,
facilities, and business communications facilities to such substitute space and
up to a six (6) month supply of stationary. All reimbursements to Tenant shall
be made within thirty (30) days of receipt of the invoice(s) therefor.

         32.06 The covenants, conditions and agreements contained in this Lease
shall bind and inure to the benefit of Landlord and Tenant and their respective
heirs, distributees, successors, administrators and executors provided, however,
that no assignment by, from, through, or under Tenant in violation of any of the
provisions hereof shall vest in the assigns any right, title, or interest
whatsoever. All provisions of this Lease are and will be binding on the
successors and permitted assigns of Landlord and Tenant.

         32.07 Time shall be and is of the essence in this Lease and with
respect to the performance of all obligations of Landlord and Tenant hereunder.

         32.08 Any services which Landlord is required to furnish pursuant to
the provisions of this Lease may, at Landlord's option, be furnished from time
to time, in whole or in part, by employees of Landlord or by the managing agent
of the Project or by one or more third persons.

         32.09 Landlord shall have the right at any time, and from time to time,
to unilaterally amend the provisions of this Lease if Landlord is advised by
counsel that all or any portion of the monies paid by Tenant to Landlord
hereunder are, or may be deemed to be, unrelated business income within the
meaning of the United States Internal Revenue Code or regulation issued
thereunder, and Tenant agrees that it will execute all documents or instruments
necessary to effect such amendment or amendments, provided that no such
amendment shall result in Tenant having to pay in the aggregate more money on
account of its occupancy of the Premises under the term of this Lease as so
amended and provided, further, that no such amendment or amendments shall result
in Tenant receiving under the provisions of this Lease less service than it is
entitled to receive, nor services of a lesser quality.

         32.10 Neither Landlord nor Landlord's agents have made any
representations or promises with respect to the physical condition of the
Building, the Land or the Premises, or with respect to the rents, leases,
expenses of operation or any other matter or thing affecting or related to the
Premises except as expressly set forth herein; and no rights, easements or
licenses are acquired by Tenant by implication or otherwise except as expressly
set forth in the provisions of this Lease.

         32.11 Annually and at any other time, Tenant shall promptly furnish
Landlord financial statements reflecting Tenant's and any Guarantor's current
financial condition. All such financial statements shall be in such form and
contain such detail as Landlord shall reasonably request.

         32.12 In case any provision of this Lease or any agreement or
instrument executed in connection herewith shall be invalid, illegal or
unenforceable, such provision shall be enforced to the fullest extent permitted
by applicable law, and the validity, legality and enforceability of the
remaining provisions hereof and thereof shall not in any way be affected or
impaired thereby. This Lease shall not be construed more strictly against one
party than against the other, merely by virtue of the fact that it may have been
prepared by counsel for one of the parties, it being recognized that both
Landlord and Tenant have contributed substantially and materially to the
preparation of this Lease.

         32.13 This Lease can be modified or amended only by a written agreement
signed by Landlord and Tenant. This Lease and the Exhibits attached hereto and
forming a part hereof set forth all of the covenants, agreements, stipulations,
promises, conditions and understandings between Landlord and Tenant concerning
the Premises, and there are no covenants, agreements, stipulations, promises,
conditions or understanding, either oral or written, between them other than set
forth herein or therein.

         32.14 Tenant will not record this Lease or a memorandum hereof, and
will not otherwise disclose the terms of this Lease to anyone other than its
attorneys, accountants or employees who need to know of its contents in order to
perform their duties for Tenant. Any other disclosure will be an Event of
Default under the Lease. Tenant agrees that Landlord shall have the right to
publish a "tombstone" or other promotional description of this Lease.

                                       21
<PAGE>

         32.15 Except as disclosed in writing to Landlord, Tenant represents and
warrants to Landlord that there are no claims for brokerage commissions or
finder's fees in connection with this Lease as a result of the contracts,
contacts or actions of Tenant, and Tenant agrees to indemnify Landlord and hold
it harmless from all liabilities arising from any such claim arising from an
alleged agreement or act by Tenant (including, without limitation, the cost of
counsel fees in connection therewith); such agreement to survive the termination
of this Lease.

         32.16 The matters set forth on Exhibit D, Special Provisions, if any,
are hereby accepted and agreed to between Landlord and Tenant and incorporated
herein by reference.

         IN WITNESS WHEREOF Landlord and Tenant have executed this Lease as of
the date and year first above written.

                       D1 EXCESS TENANT IMPROVEMENT COSTS.

         Landlord shall construct the Tenant Improvements up to a cost of Four
Hundred Sixty-Six Thousand Eight Hundred Twenty Dollars ($466,820.00) (the
"Tenant Improvement Allowance"). In the event the cost of completing the Tenant
Improvements is less than the Tenant Improvement Allowance, Landlord shall
retain the difference and Tenant shall have no claim for and not be entitled to
receive any such sums. In the event the estimated cost of completing the Tenant
Improvements in accordance with the Plans shall at anytime exceed one hundred
five percent (105%) of the Tenant Improvement Allowance, Tenant shall pay
Landlord, within ten (10) business days of request for such payment (which
request will come no more than twice monthly), the difference between the
estimated cost of completion and the Tenant Improvement Allowance on a
percentage of completion basis. If the estimated cost of completion of the
Tenant Improvements is less than one hundred five percent (105%) of the Tenant
Improvement Allowance, Tenant shall pay Landlord the difference between the
actual cost of completion and the Tenant Improvement Allowance when the Tenant
Improvements are substantially complete.

                                 D2 OPTION TERM.

Provided that no default exists under this Lease and provided no default shall
have existed which is uncured within a period of one (1) year prior to the
notification hereunder by Tenant shall have the right to extend the Initial Term
of this Lease for one (1) term of five (5) Lease Years (the "Option Term"),
provided that Tenant shall deliver to Landlord written notice of its election to
extend the Term of this Lease at least twelve (12) months prior to the
expiration date of the Initial Term of this Lease. The failure of Tenant to
exercise its right to extend the Lease for any Option Term shall void all
subsequent Option Terms. Terms, covenants and conditions applicable to the
Option term shall be as then promulgated by Landlord, except as hereinafter
specifically set forth. Except for the granting of this Option Term and except
as expressly otherwise provided herein this Lease, the rent shall be adjusted as
below. The Initial Term and the Option Term, if exercised, are sometimes
collectively referred to hereinafter as the "Term". Base Rent for the Option
Term shall be as follows: the rent for the Option Term shall be at then
prevailing market level for comparable renewal space at the Building but not, in
any event, less than the Base Rent payable at the end of the current Term.

                        D3 LETTER OF CREDIT AS SECURITY.

Upon the execution hereof by Tenant, Tenant shall deliver a letter of credit to
Landlord in the amount set forth in Section 1.01(j) as the security deposit
and/or as security for the performance of the Guaranty. The letter of credit
shall not decline during the term of the Lease. The bank issuing the letter of
credit shall provide that the letter of credit shall not be cancelled or changed
in any manner for any reason whatsoever except upon thirty (30) days prior
written notice to Landlord. In the event any such notice is sent to Landlord,
Landlord shall have the right, but not the obligation to draw the entire amount
of the letter of credit and hold and/or apply the cash as a security deposit
hereunder. The letter of credit shall have an expiration date of not less than
one (1) year from the Commencement Date and shall be renewed by Tenant each and
every year during the term of this Lease so that the letter of credit (and or
replacements thereof issued by the same bank or another banking institution
meeting all of the requirements described in this Section) may be drawn down
through and including the sixtieth (60th) day after the Expiration Date. The
letter of credit shall be renewed thirty (30) days before its expiration and
Tenant shall deliver to Landlord a renewed or new letter of credit not less than
thirty (30) days prior to the expiration date of the letter of credit and if the
renewed letter of credit has not been timely delivered, Landlord may draw the
entire amount of the letter of credit and/or apply the cash as a security
deposit hereunder. Tenant shall keep that letter of credit (and/or replacements
thereof issued by the same bank or another banking institution having offices in
Michigan) in force during the entire term of the Lease. In the event the letter
of credit provides that it shall expire prior to the end of the term of this
Lease, the letter of credit shall be renewed thirty (30) days before its
expiration and Tenant shall deliver to Landlord a renewed or new letter of
credit not less than thirty (30) days prior to the expiration date of the letter
of credit and if the renewed letter of credit has not been timely delivered,
Landlord may draw the entire amount of the letter of credit and hold and/or
apply the cash as a security deposit hereunder. The letter of credit shall be
(i) irrevocable, (ii) unconditional, (iii) issued by a bank or other financial
institution (A) with an office in the State of Michigan which is reasonably
acceptable to Landlord, (B) that is a member of the Federal Reserve, (C) that is
rated "B" or better by the Thompson Bank Watch, and (D) approved by Landlord,
(iv) able to be drawn upon and confirmed by a bank or other financial
institution located in New York City, New York which is reasonably acceptable to
Landlord, (v) assignable without charge and (vi) in form reasonably acceptable
to Landlord. The letter of credit shall permit Landlord to draw down either
partial draws or the entire amount thereof (which shall thereafter be held and
applied in accordance with

                                       29

the terms of this Lease and law applicable to security deposits) upon
presentation of a sight draft executed by an authorized agent of Landlord.

                           D4 RIGHT OF FIRST REFUSAL.

         the Protected Space is vacant as of the date of this Lease, all tenants
         who first occupy such space pursuant to, under or through a lease with
         Landlord.

                  (b) Provided (i) Tenant is the Tenant originally named herein,

this Lease Landlord shall receive an offer to lease all or any part of the
Protected Space from any person or entity other than an Initial Tenant (or their
affiliates) which Landlord may desire to accept, Landlord shall offer to Tenant
the right to lease the RFR Space (as defined below) by notifying Tenant in
writing (the "RFR Notice") of the basic terms of such offer. The RFR Notice
shall include the base rent, square footage and location of the space (which may
include all or only a portion of the Protected Space together with all or a
portion of any other space in the Project, all such described space being the
"RFR Space"), tenant improvement allowance, and term of the offer to lease. If
the space described in the offer to lease Landlord receives includes all or a
portion of the Protected Space plus other space in the Project, Landlord shall
have the right, in its sole and absolute discretion, to have the RFR Space
consist of all or the portion of the Protected Space with or without the other
space. If the space described in the offer to lease Landlord receives is for
only a portion of the Protected Space, Landlord shall have the right, in its
sole and absolute discretion, to have the RFR Space consist of all or the
portion of the Protected Space. In addition, if the term described in the offer
to lease Landlord receives extends beyond the Initial Term of this Lease,
Landlord shall have the right, in its sole and absolute discretion, to have the
RFR Notice state that the term for the RFR Space will be co-terminus with the
Initial Term (and in such case Landlord shall have the right to make an
appropriate adjustment to the base rent, tenant improvement allowance and other
terms before stating them in the RFR Notice), or to have the RFR Notice state
that the term for the RFR Space is the longer term.

D4.02 Tenant may accept the offer set forth in the RFR Notice by delivering to
Landlord an unconditional acceptance (hereinafter called the "Tenant
Acceptance") of such offer within ten (10) days after delivery by Landlord of
the RFR Notice to Tenant. Tenant shall only have the right to accept the RFR
Notice in its entirety, not in part, and only on the terms provided in the RFR
Notice. If Tenant timely delivers the Tenant Acceptance, the RFR Space shall be
added to and included in the Premises on the later to occur of (i) the day that
Landlord receives the Tenant Acceptance or (ii) the date such RFR Space shall
become available for Tenant's possession as set forth in the notice and if none
is set forth in the notice, then determined in accordance with Section D4.03
(hereinafter called the "RFR Space Inclusion Date"). If Tenant does not accept
the RFR Notice within the ten (10) day period set forth above, Landlord may (but
shall not be obligated to) proceed to lease all or any portion of Protected
Space or the RFR Space, and Tenant shall no longer have any rights with respect
to the Protected Space or the RFR Space whatsoever, whether all or any portion
of such space is leased as described in the RFR Notice or otherwise at any time,
to any person or entity and under any terms and conditions. Time shall be of the
essence with respect to the giving of the Tenant Acceptance.

Space in accordance with the terms of the RFR Notice and, if none are stated,
then otherwise in its condition and state of repair existing as of the RFR Space

the RFR Notice, Landlord shall not be required to perform any work, supply any
materials or incur any expense to prepare such space for Tenant's occupancy.
Within thirty (30) days after giving the Tenant Acceptance, Tenant shall execute
a lease amendment providing for the addition of the RFR Space to the Premises
and the modification of all lease terms affected by the addition of the RFR
Space to the Premises. Unless otherwise provided in the RFR Notice, the lease
amendment shall provide that the RFR Space shall become available for Tenant's
possession within ninety (90) days after the date of the RFR Notice and such
date shall be considered the "Scheduled Occupancy Date" described in Section
2.04 of this Lease and the provisions of Sections 2 and 3 shall apply to the
Plans for the Tenant Improvements, the construction of the Tenant Improvements,
the payment for the Tenant Improvements,

Inclusion Date and Commencement Date for the term for the RFR Space.

D4.04 Tenant must accept all RFR Space offered by Landlord at any one time if it
desires to accept any of such RFR Space. In the event Tenant shall accept any
RFR Space offered by Landlord in any RFR Notice, Tenant shall be deemed to have
irrevocably waived its right to lease any remaining portion of the Protected
Space. If Tenant at any time declines any RFR Space offered by Landlord, Tenant
shall be deemed to have irrevocably waived all further rights under this Section
D4.

D4.05 Notwithstanding the foregoing, Tenant's rights hereunder are subject and
subordinate, in each and every respect, to any rights of first refusal, options
or other rights, however designated, of any tenant of the Building under any
existing Building lease at the time of execution of this Lease. In no event
shall Landlord have any obligation to send an RFR Notice to Tenant for the lease
of any of the Protected Space under lease to any Initial Tenant (or their
affiliate), and upon the leasing of all or any portion of the Protected Space to
any Initial Tenant (or their Affiliate), Tenant shall have no further rights
under this Section D4 and shall have no further right to lease or be offered the
opportunity to lease all or any portion of the Protected Spaces.

D4.06 All rights under this Section D4 shall terminate upon the expiration of
the twenty-fourth (24th) month of the Initial Term of this Lease.

D4.07 Landlord shall use its best efforts to comply with the provisions of this
Section D4, but its failure to comply shall not constitute an event of default
under this Lease.

                               D5 NON-DISTURBANCE.

In the event of subordination of this Lease, the subordination shall be
conditioned upon the agreement of the mortgagee or lessor that in the event of
foreclosure or the assertion of any other rights under the mortgage or lease,
this Lease and the rights of Tenant hereunder shall continue in effect and shall
not be terminated or disturbed so long as Tenant continues to perform and no
Event of Default exists under this Lease.

                            D6 TENANT REVIEW RIGHT.

Provide no Event of Default exists under the Lease, Tenant shall have the right,
at its sole cost and expense, to review Landlord's records at the Manager's
office relating to Real Estate Taxes and Operating Expenses for the Base Year
and any subsequent year solely for the purpose of determining the amounts paid
by Tenant pursuant to Section 6 of this Lease. However, Tenant may only conduct
a review (i) upon reasonable notice to Landlord so as to allow Landlord
sufficient time to compile its records and make them available to Tenant at
Manager's office and upon reimbursement to Landlord for its costs and expenses
incurred in connection with such review; (ii) not more than sixty (60) days
after Tenant receives the Annual Statement of Real Estate Taxes and Operating
Expenses for the subject year, regardless of whether the year in question is the
Base Year or any subsequent year; (iii) not more than once during any Lease
Year; and (iv) by using an internal auditor or an independent certified public
accountant acceptable to Landlord in all respects which are not working for
Tenant on a contingency fee basis.

                           D7 TENANT'S RIGHT TO CURE.

If Landlord shall default in any of its obligations under this Lease, Tenant
shall give written notice of such default to Landlord. Landlord shall cure any
material default within thirty (30) days after the date of such notice or, in
the event that such default is of a character as to require more than thirty
(30) days to cure, Landlord shall commence curing such default within thirty
(30) days and shall diligently pursue such cure. If any material default relates
to a condition that is for the exclusive benefit of the Premises and as a result
thereof Tenant is denied the use of the Premises and Landlord fails to cure such
default in all material respects within the applicable time period, Tenant shall
have the right to cure such default in a good and workmanlike manner and
Landlord shall reimburse Tenant within thirty (30) days of demand for its
reasonable costs in performing such work.
