         Every certificate or opinion with respect to compliance with a
condition provided for in this Indenture shall include:

                  (a) a statement that each individual signing such certificate
         or opinion has read such condition and the definitions herein relating
         thereto;

                  (b) a brief statement as to the nature and scope of the
         examination or investigation upon which the statements or opinions
         contained in such certificate or opinion are based;

                  (c) a statement that, in the opinion of each such individual,
         he has made such examination or investigation as is necessary to enable
         him to express an informed opinion as to whether or not such condition
         has been complied with; and

                  (d) a statement as to whether, in the opinion of each such
         individual, such condition has been complied with.

         SECTION 1.3 Form of Documents Delivered to Trustee. In any case where

insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations

         SECTION 1.4 Acts of Holders: Record Dates. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided or
permitted by this Indenture to be given or taken by Holders may be embodied in
and evidenced by one or more instruments of substantially similar tenor signed
by such Holders in person or by an agent duly appointed in writing; and, except
as herein otherwise expressly provided, such action shall become effective when
such instrument or instruments are delivered to the Trustee and, where it is
hereby expressly required, to the Company. Such instrument or instruments (and
the action embodied therein and evidenced thereby) are herein sometimes referred
to as the "Act" of the Holders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall
be sufficient for any purpose of this Indenture and (subject to Section 6.1)
conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved by the affidavit of a witness of such
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 ownership of Notes shall be proved by the Note
Register.

                  (d) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Note shall bind every future
Holder of the same Note and the Holder of every Note 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 Note.

                                       -8-




                  (e) The Company may set any day as a record date for the
purpose of determining the Holders of Outstanding Notes entitled to give or take
any request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given or taken by Holders
of Notes; provided that the Company may not set a record date for, and the
provisions of this paragraph shall not apply with respect to, the giving or
making of any notice, declaration, request or direction referred to in the next
paragraph. If any record date is set pursuant to this paragraph, the Holders of
Outstanding Notes on such record date, and no other Holders, shall be entitled
to take the relevant action, whether or not such Holders remain Holders after
such record date; provided that no such action shall be effective hereunder
unless taken on or prior to the applicable Expiration Date by Holders of the
requisite principal amount of Outstanding Notes on such record date; and
provided, further, that for the purpose of determining whether Holders of the
requisite principal amount of such Notes have taken such action, no Note shall
be deemed to have been Outstanding on such record date unless it is also
Outstanding on the date such action is to become effective. Nothing in this
paragraph shall prevent the Company from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be canceled and of no effect), nor shall anything in
this paragraph be construed to render ineffective any action taken by Holders of
the requisite principal amount of Outstanding Notes on the date such action is
taken. Promptly after any record date is set pursuant to this paragraph, the
Company, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the
Trustee in writing and to each Holder of Notes in the manner set forth in
Section 1.6.

                  (f) The Trustee may set any day as a record date for the
purpose of determining the Holders of Outstanding Notes entitled to join in the
giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 5.2, (iii) any request to institute
proceedings referred to in Section 5.7(b) or (iv) any direction referred to in
Section 5.12. If any record date is set pursuant to this paragraph, the Holders
of Outstanding Notes on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Notes on such record date; and provided, further, that for the purpose of
determining whether Holders of the requisite principal amount of such Notes have
taken such action, no Note shall be deemed to have been Outstanding on such
record date unless it is also Outstanding on the date such action is to become
effective. Nothing in this paragraph shall be construed to prevent the Trustee
from setting a new record date for any action (whereupon the record date
previously set shall automatically and without any action by any Person be
canceled and of no effect), nor shall anything in this paragraph be construed to
render ineffective any action taken by Holders of the requisite principal amount
of Outstanding Notes on the date such action is taken. Promptly after any record
date is set pursuant to this paragraph, the Trustee, at the Company's expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Company in writing and to each
Holder of Notes in the manner set forth in Section 1.6.


                                       -9-




                  (g) With respect to any record date set pursuant to this
Section, the party hereto that sets such record date may designate any day as
the "Expiration Date" and from time to time may change the Expiration Date to
any earlier or later day, provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto in
writing, and to each Holder of Notes in the manner set forth in Section 1.6, at
least five (5) Business Days before the proposed new Expiration Date.
Notwithstanding the foregoing, no Expiration Date shall be later than the 180th
day after the applicable record date and, if an Expiration Date is not
designated with respect to any record date set pursuant to this Section, the
party hereto that set such record date shall be deemed to have designated the
180th day after such record date as the Expiration Date with respect thereto.

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

         SECTION 1.5 Notices 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,

                  (a) the Trustee by any Holder or by the Company shall be
         sufficiently given if made, given, furnished or filed in writing to or
         with the Trustee at its Corporate Trust Office, Attention: Corporate
         Trust Administration, or at any other address previously furnished in
         writing to the Company by the Trustee, or

                  (b) the Company by the Trustee or by any Holder shall be
         sufficiently given (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 instrument or at any other address previously
         furnished in writing to the Trustee by the Company.

         SECTION 1.6 Notice to Holders; Waiver. Where this Indenture provides
for notice to Holders of any event, such notice shall be sufficiently given
(unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at his
address as it appears in the Note Register, not later than the latest date (if
any), and not earlier than the earliest date (if any), prescribed for the giving
of such notice. In any case where notice to Holders is given by mail, neither
the failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders. 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 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.


                                      -10-





         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 by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder; provided, that
this paragraph shall not apply to any notice required by the Trust Indenture Act
to be transmitted by mail.

         SECTION 1.7 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 1.8 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 1.9 Separability Clause. In case any provision in this
Indenture or in the Notes 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 1.10 Benefits of Indenture. Nothing in this Indenture or in the
Notes, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, the holders of Senior Indebtedness and
the Holders of Notes, any benefit or any legal or equitable right, remedy or
claim under this Indenture.

         SECTION 1.11  Governing Law.  THIS INDENTURE AND THE NOTES SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.

         SECTION 1.12 Legal Holidays. In any case where any Interest Payment
Date, Redemption Date or Stated Maturity of any Note or the last date on which a
Holder has the right to convert his Notes shall not be a Business Day then
(notwithstanding any other provision of this Indenture or of the Notes) payment
of interest or principal (and premium, if any) or conversion of the Notes need
not be made on such date, but may be made on the next succeeding Business Day
with the same force and effect as if made on the Interest Payment Date,
Redemption Date or at the Stated Maturity, or on such last day for conversion,
provided that no interest shall accrue for the period from and after such
Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.

SENTENCE HEREOF.

         SECTION 2.3 Form of Reverse of Note. This Note is one of a duly
authorized issue of Notes of the Company designated as its ___% Callable
Convertible Subordinated Notes due 2008 (herein called the "Notes"), limited in
aggregate principal amount to U.S.$8,000,000, issued under an Indenture, dated
as of ______ __, 1998 (herein called the "Indenture"), between the Company and
_______________ ________________________, as Trustee for the Holders of Notes
issued under said Indenture (herein called the "Trustee", which term includes
any successor trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the

                                      -13-




Company, the Trustee, the holders of Senior Indebtedness and the Holders of the
Notes and of the terms upon which the Notes are, and are to be, authenticated
and delivered.

         Subject to and upon compliance with the provisions of the Indenture,
the Holder of this Note is entitled, at his option, at any time after ______ __,
2000, but on or before the close of business on the Business Day immediately
preceding ______ __, 2008, or in case this Note or a portion hereof is called
for redemption, then in respect of this Note or such portion hereof until and
including, but (unless the Company defaults in making the payment due upon
redemption) not after, the close of business on the Business Day immediately
preceding the Redemption Date, to convert this Note (or any portion of the
principal amount hereof), at the principal amount hereof, or of such portion,
into fully paid and non-assessable Common Shares of the Company at a conversion
price equal to U.S.$20.00 aggregate principal amount of Notes for each Common
Share (or at the current adjusted conversion price if an adjustment has been
made as provided in Article XIII of the Indenture) by surrender of this Note,
duly endorsed or assigned to the Company or in blank, to the Company at its
office accompanied by the conversion notice hereon executed by the Holder hereof
evidencing such Holder's election to convert this Note, or if less than the
entire principal amount hereof is to be converted, the portion hereof to be
converted, and, in case such surrender shall be made during the period from the
close of business on any Regular Record Date to the opening of business on the
corresponding Interest Payment Date (unless this Note or the portion hereof
being converted has been called for redemption on a Redemption Date within such
period between and including such Regular Record Date and such Interest Payment
Date), also accompanied by payment in funds acceptable to the Company of an
amount equal to the interest payable on such Interest Payment Date on the
principal amount of this Note then being converted. Subject to the aforesaid
requirement for payment of interest and, in the case of a conversion after the
close of business on any Regular Record Date and on or before the corresponding
Interest Payment Date, to the right of the Holder of this Note (or any
Predecessor Note) of record at such Regular Record Date to receive an
installment of interest (even if the Note has been called for redemption on a
Redemption Date within such period), no payment or adjustment is to be made on
conversion for interest accrued hereon or for dividends on the Common Shares
issued on conversion. Upon an Event of Default (as set forth in Sections 5.2 and
6.2 of the Indenture) or Change in Control (as defined in Section 8.1 of the
Indenture), the Holder of this Note shall, at his option, have the right to
convert this Note (or any portion of the principal amount hereof), pursuant to
the terms above, but in no event may the holder of this Note convert prior to
one year after the date of original issuance. No fractions of shares or scrip
representing fractions of shares will be issued on conversion, but instead of
any fractional interest the Company shall pay a cash adjustment or round up to
the next higher whole share as provided in Article XIII of the Indenture. The
conversion price is subject to adjustment as provided in Article XIII of the
Indenture. In addition, the Indenture provides that in case of certain
reclassifications, consolidations, mergers, sales or transfers of assets or
other transactions pursuant to which the Common Shares are converted into the
right to receive other securities, cash or other property, the Indenture shall
be amended, without the consent of any Holders of Notes, so that this Note, if
then outstanding, will be convertible thereafter, during the period this Note
shall be convertible as specified above, only into the kind and amount of
securities, cash and other property receivable upon the transaction by a holder
of the number of Common Shares into which this Note might have been converted
immediately prior to such transaction (assuming such holder of Common

                                      -14-




Shares failed to exercise any rights of election and received per share the kind
and amount received per share by a plurality of non-electing shares).

         The Company will furnish to any Holder, upon request and without
charge, copies of the Certificate of Incorporation and By-laws of the Company
then in effect. Any such request may be addressed to the Company or to the
Security Registrar.

         The Notes are subject to redemption, as a whole or from time to time in
part, at the option of the Company upon not less than twenty (30) days' or more
than sixty (60) days' notice by mail, at any time on or after ______ __, 2000,
through ______ __, 2008, at 100.00% of the principal amount, plus accrued and
unpaid interest on the Notes, or part thereof being redeemed, to the date of
redemption.

         The Notes do not have the benefit of any sinking fund.

         In the event of redemption or conversion of this Note in part only, a
new Note or Notes for the unredeemed, unconverted portion hereof will be issued
in the name of the Holder hereof upon the cancellation hereof.

         The indebtedness evidenced by this Note is, to the extent provided in
the Indenture, subordinate and subject in right of payment to the prior payment
in full of all Senior Indebtedness, and this Note is issued subject to the
provisions of the Indenture with respect thereto. Each Holder of this Note, by
accepting the same, (a) agrees to and shall be bound by such provisions, (b)
authorizes and directs the Trustee on his behalf to take such action as may be
necessary or appropriate to effectuate the subordination so provided and (c)
appoints the Trustee his attorney-in-fact for any and all such purposes.

         If an Event of Default shall occur and be continuing, the principal of
all the Notes may be declared due and payable in the manner and with the effect
provided in Article V of the Indenture.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Notes under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Notes at the time Outstanding. The
indenture also contains provisions permitting the Holders of a majority in
aggregate principal amount of the Notes at the time Outstanding, on behalf of
the Holders of all the Notes, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Note shall
be conclusive and binding upon such Holder and upon all future Holders of this
Note and of any Note issued upon the registration of transfer hereof or in
exchange hereof or in lieu hereof, whether or not notation of such consent or

delivered upon registration of transfer of, or in exchange for, or in lieu of,
other Notes of the series pursuant to Sections 3.4, 3.5, 9.5, 11.8 or 13.2 and
except for Notes which, pursuant to Section 3.3, are deemed never to have been

                                      -18-




         Payment of the principal of, premium, if any, and interest on this Note
will be made at the Corporate Trust Office, in such coin or currency of the
United States of America as at the time of payment is legal tender for payment

maintained with a bank in the states of New York, New Jersey, Maryland or
Pennsylvania.

         The Notes shall be redeemable by the Company as provided in Article XI.

         The Notes shall be subordinated in right of payment to the prior

         The Notes shall be convertible as provided in Article XIII.

         SECTION 3.2 Denominations. The Notes shall be issuable only in
registered form without coupons in any denomination. There shall be no minimum
denomination.

         SECTION 3.3 Execution, Authentication, Delivery and Dating. The Notes

President, under its corporate seal reproduced thereon and attested by its
Secretary. The signature of any of these officers on the Notes may be manual or
facsimile.

         Notes 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 Notes or did not hold
such offices at the date of such Notes.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Notes of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Notes; and the Trustee in accordance with
such Company Order shall authenticate and deliver such Notes as in this
Indenture provided and not otherwise.

         Each Note shall be dated the date of its authentication.

         No Note shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Note a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any Note
shall be conclusive evidence, and the only evidence, that such Note has been
duly authenticated and delivered hereunder.

         SECTION 3.4  Registration: Registration of Transfer and Exchange.

         (a) The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register (referred to as the "Note Register") in which, subject to
such reasonable regulations as it may prescribe, the Company shall provide for
the registration of Notes and of transfers and exchanges thereof. The Trustee is
hereby appointed "Note Registrar" for the purpose of registering Notes and

                                      -19-




transfers and exchanges thereof as herein provided. The Notes are only
transferable in accordance with the laws of descent and distribution or in
connection with a gift without consideration. Upon surrender for registration of
transfer or exchange of any Note at an office or agency of the Company
designated pursuant to Section 10.2 for such purpose, accompanied by a written
instrument of transfer or exchange in the form provided by the Company, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Notes of the
same series, of a like aggregate principal amount. The Company shall not
recognize or record on its Note Register a transfer of any Note other than in
accordance with the laws of descent and distribution or in connection with a
gift without consideration.

                  (i) Transfer and Exchange of Notes. When Notes are presented
         to the Note Registrar with a request:

                  (A) to register the transfer of such Notes; or

                  (B) to exchange such Notes for an equal principal amount of
Notes,

                  the Note Registrar shall register the transfer or make the
         exchange as requested if its reasonable requirements for such
         transaction are met; provided, however, that the Notes surrendered for
         transfer or exchange shall be duly endorsed or accompanied by a written
         instrument of transfer in form reasonably satisfactory to the Company
         and the Note Registrar, duly executed by the Holder thereof or his
         attorney duly authorized in writing.

         (b) Every Note shall be subject to the restrictions on transfer
provided in the legends required by Section 2.1. Whenever any Note is presented
or surrendered for registration of transfer or for exchange for a Note
registered in a name other than that of the Holder, such Note must be
accompanied by a certificate in substantially the form set forth in Section 2.6,
dated the date of such surrender and signed by the Holder of such Note, as to
compliance with such restrictions on transfer. The Note Registrar shall not be
required to accept for such registration of transfer or exchange any Note not so
accompanied by a properly completed certificate.

         (c) As used in the preceding two paragraphs of this Section 3.4, the
term "transfer" encompasses any sale, pledge, transfer, hypothecation or other
disposition of any Note.

         (d) No service charge shall be made for any registration of transfer or
exchange of Notes, 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 Notes, other than exchanges
pursuant to Section 9.5, 11.8, or 13.2 not involving any transfer.

         (e) Except as permitted by Section 11.9 and 13.1, the Company shall not
be required (i) to issue, register the transfer of or exchange any Note during a
period beginning at the opening of business fifteen (15) days before the day of
the mailing of a notice of redemption of Notes selected for redemption under
Section 11.4 and ending at the close of business on the day of such mailing, or
(ii) to register the transfer of or exchange any Note so selected for redemption
in whole or in part, except the unredeemed portion of any Note being redeemed in
part.

                                      -20-




         SECTION 3.5 Mutilated, Destroyed, Lost and Stolen Notes. If any
mutilated Note is surrendered to the Trustee, the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a new Note of like
tenor and principal amount and bearing a number not contemporaneously
outstanding.

         If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Note 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 Note 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 Note, a new Note of like
tenor and principal amount and bearing a number not contemporaneously
outstanding.

         In case any such mutilated, destroyed, lost or stolen Note has become
or is about to become due and payable, the Company in its discretion, but
subject to any conversion rights, may, instead of issuing a new Note, pay such
Note.

         Upon the issuance, authentication and delivery by the Trustee of any
new Note under this Section, the Company may require the 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 Note issued, authenticated and delivered by the Trustee
pursuant to this Section in lieu of any destroyed, lost or stolen Note shall
constitute an original additional contractual obligation of the Company, whether
or not the destroyed, lost or stolen Note shall be at any time enforceable by
anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Notes 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 Notes.

         SECTION 3.6 Payment of Interest: Interest Rights Preserved. Interest on
any Note which is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name that Note (or
one or more Predecessor Notes) is registered at the close of business on the
Regular Record Date for payment of such interest.

         If the Company shall be required by law to deduct any taxes from any
sum of interest payable hereunder to a Holder, (i) the Company shall make such
deductions and shall pay the full amount deducted to the relevant taxing
authority in accordance with applicable law and (ii) the amount of such
deduction shall be treated for purposes hereof as a payment of interest.

         Any interest on any Note 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

                                      -21-




to the Holder on the relevant Regular Record Date, and such Defaulted Interest
may be paid by the Company, at its election in each case, as provided in Clause
(a) or (b) below:

                  (a) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Notes (or their respective
         Predecessor Notes) 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
         Note 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 (a) provided. Thereupon,
         the Trustee shall fix a Special Record Date for the payment of such
         Defaulted Interest which shall be not more than fifteen (15) days and
         not less than ten (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 at his address as it
         appears in the Note Register, not less than ten (10) days prior to 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
         Notes (or their respective Predecessor Notes) are registered at the
         close of business on such Special Record Date and shall no longer be
         payable pursuant to the following Clause (b).

                  (b) The Company may make payment of any Defaulted Interest in
         any other lawful manner not inconsistent with the requirements of any
         securities exchange on which the Notes may be listed, and upon such
         notice as may be required by such exchange, if, after notice given by
         the Company to the Trustee of the proposed payment pursuant to this
         Clause (b), such manner of payment shall be deemed practicable by the
         Trustee.

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

         In the case of any Note which is converted after any Regular Record
Date and on or prior to the corresponding Interest Payment Date, interest on
such Note whose Stated Maturity is on such Interest Payment Date shall be deemed
to continue to accrue and shall be payable on such Interest Payment Date
notwithstanding such conversion and notwithstanding that such Note may have been
called for redemption on a Redemption Date within such period, and such interest
(whether or not punctually paid or duly provided for) shall be paid to the
Person in whose name that Note (or one or more Predecessor Notes) is registered
at the close of business on such Regular Record Date. Except as otherwise
expressly provided in the immediately preceding sentence, in the case of any
Note which is converted, interest whose Stated Maturity is after the date of
conversion of such Note

                                      -22-




shall not be payable (although such accrued and unpaid interest will be deemed
paid by the appropriate portion of the Common Shares received by the holders
upon such conversion).

         SECTION 3.7 Persons Deemed Owners. Prior to due presentment of a Note
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 Note is
registered as the owner of such Note for the purpose of receiving payment of
principal of, premium, if any, and (subject to Section 3.6) interest on such
Note and for all other purposes whatsoever, whether or not such Note 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.

         SECTION 3.8 Cancellation. All Notes surrendered for payment,
redemption, registration of transfer or exchange or conversion shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly canceled by it. The Company may at any time deliver to the
Trustee for cancellation any Notes previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and all
Notes so delivered shall be promptly canceled by the Trustee. No Notes shall be
authenticated in lieu of or in exchange for any Notes canceled as provided in
this Section, except as expressly permitted by this Indenture. All canceled
Notes held by the Trustee shall be disposed of as directed by a Company Order.

         SECTION 3.9 Computation of Interest. Interest on the Notes of each
series shall be computed on the basis of a 360-day year of twelve 30-day months.


                                   ARTICLE IV

                           Satisfaction and Discharge

         SECTION 4.1 Satisfaction and Discharge of Indenture. This Indenture
shall upon Company request cease to be of further effect (except as to any
surviving rights of conversion, registration of transfer or exchange of Notes
herein expressly provided for), and the Trustee, at the expense of the Company,
shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture, when

         (a)      either

                  (i)  all Notes theretofore authenticated and delivered (other
         than (A) Notes which have been destroyed, lost or stolen and which have
         been replaced or paid as provided in Section 3.5 and (B) Notes 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 10.3)
         have been delivered to the Trustee for cancellation; or

                  (ii) all such Notes not theretofore delivered to the Trustee
for cancellation:

                       (A) have become due and payable, or

                                      -23-




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

                       (C) 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 (A), (B) or (C) above, has
                  deposited or caused to be deposited irrevocably with the
                  Trustee as trust funds in trust for the benefit of Holders of
                  Outstanding Notes an amount sufficient to pay and discharge
                  the entire indebtedness on such Notes not theretofore
                  delivered to the Trustee for cancellation, for principal (and
                  premium, if any) and interest to the date of such deposit (in
                  the case of Notes which have become due and payable) or to the
                  Stated Maturity or Redemption Date, as the case may be;

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

         (c) the Company has delivered to the Trustee an Officers' Certificate
         and an Opinion of Counsel, each stating that (i) all conditions
         precedent herein provided for relating to the satisfaction and
         discharge of this Indenture have been complied with and (ii) such
         deposit will not result in any breach or violation of Article XII and
         the money so deposited with the Trustee is not subject to the
         provisions of Article XII in any respect; and

         (d) no Event of Default which, with notice or lapse of time, or both,
         would become an Event of Default with respect to the Notes shall have
         occurred and be continuing on the date of such deposit.

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.7, the obligations of
the Trustee to any Authenticating Agent under Section 6.14 and, if money shall
have been deposited with the Trustee pursuant to subclause (ii) of Clause (a) of
this Section, the obligations of the Trustee under Section 4.2 and the last
paragraph of Section 10.3 shall survive.

         SECTION 4.2 Application of Trust Money. Subject to the provisions of
the last paragraph of Section 10.3, all money deposited with the Trustee
pursuant to Section 4.1 shall be held in trust and applied by it, in accordance
with the provisions of the Notes 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 premium, if any) and interest for whose payment such money
has been deposited with or received by the Trustee. All moneys deposited with or
received by the Trustee pursuant to Section 4.1 (and held by it or any Paying
Agent) for the payment of Notes subsequently converted shall be returned to the
Company upon Company Request.

                                    Remedies

         SECTION 5.1 Events of Default. "Event of Default", wherever used
herein, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be occasioned by the provisions of Article
XII or be voluntary or involuntary or be effected by operation of law or
pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body):

                  (a) default in the payment of any interest upon any Note when
         it becomes due and payable, and continuance of such default for a
         period of thirty (30) days (whether or not such payment is prohibited
         by the provisions of Article XII); or

                  (b) default in the payment of the principal of (or premium, if
         any, on) any Note at its Maturity (whether or not such payment is
         prohibited by the provisions of Article XII); or

                  (c) 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), and continuance of such default
         or breach for a period of sixty (60) 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 50% in principal
         amount of the Outstanding Notes 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

                  (d) a default under any bonds, debentures, notes or other
         evidences of indebtedness for money borrowed by the Company under any
         mortgages, indentures or instruments under which there may be issued or
         by which there may be secured or evidenced any indebtedness for money
         borrowed by the Company, whether such indebtedness now exists or shall
         hereafter be created, which indebtedness, individually has an aggregate
         principal amount outstanding in excess of U.S.$30,000,000, which
         default shall constitute a failure to pay any portion of the principal
         or interest of such indebtedness when due and payable after the
         expiration of any applicable grace or cure period with respect thereto
         or shall have resulted in such indebtedness becoming or being declared
         due and payable prior to the date on which it would otherwise have
         become due and payable, without such indebtedness having been
         discharged, or such acceleration having been rescinded or annulled,
         within a period of three (3) days after there shall have 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 50% in principal
         amount of the Outstanding Notes a written notice specifying such
         default and requiring the Company to cause such indebtedness to be
         discharged or cause such acceleration to be rescinded or annulled and
         stating that such notice is a "Notice of Default" hereunder; or


                                      -25-





                  (e) 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
         involuntary case or proceeding under any applicable Federal or State

         decree or order adjudging the Company a 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 their respective
         properties, or ordering the winding up or liquidation of the affairs of
         the Company, 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 sixty (60) consecutive days; or

                  (f) the commencement by the Company of a voluntary case or
         proceeding under any applicable Federal or State bankruptcy,
         insolvency, reorganization or other similar law or of any other case or
         proceeding to be adjudicated a bankrupt or insolvent, or the consent by
         either the Company 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 to the commencement of any bankruptcy or
         insolvency case or proceeding against either the Company, or the filing
         by either the Company of a petition or answer or consent seeking
         reorganization or relief under any applicable Federal or State law, or
         the consent by either the Company to the filing of such petition or to
         the appointment of or taking possession by a custodian, receiver,
         liquidator, assignee, trustee, sequestrator or other similar official
         of the Company or of any substantial part of their respective
         properties, or the making by either the Company of an assignment for
         the benefit of creditors, or the admission by either the Company in
         writing of an inability to pay the debts of either the Company
         generally as they become due, or the taking of corporate action by the
         Company in furtherance of any such action; provided, however, that,
         subject to the provisions of Section 6.1 and 6.2, the Trustee shall not
         be deemed to have knowledge of any default under Section 5.1(d) unless
         either (A) a Responsible Officer of the Trustee in its Corporate Trust
         Department shall have actual knowledge of such default or (B) the
         Trustee shall have received written notice thereof from the Company,
         from any Holder, from the holder of any such indebtedness, or from the
         trustee under any such mortgage, indenture or other instrument.

         SECTION 5.2 Acceleration of Maturity, Rescission, Annulment and
Conversion.

         (a) If an Event of Default (other than an Event of Default specified in
Section 5.1(e) or 5.1(f)) occurs and is continuing, then in every such case the
Trustee or the Holders of not less than 50% in principal amount of the
Outstanding Notes may declare the principal of all the Notes 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 and any
accrued interest thereon shall become immediately due and payable. If an Event
of Default specified in Section 5.1(e) or 5.1(f) occurs, the principal of, and
accrued interest on, all the Notes shall automatically, and without any
declaration or other action on the part of the Trustee or any Holder, become
immediately due and payable.

                                      -26-




         (b) At any time after such a declaration of acceleration 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 V; provided, the Holders of a
majority in principal amount of the Outstanding Notes, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequences if:

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

                  (A) all overdue interest on all Notes,

                  (B) the principal of (and premium, if any, on) any Notes which
         have become due otherwise than by such declaration of acceleration and
         interest thereon at the rate borne by the Notes,

                  (C) to the extent that payment of such interest is lawful,
         interest upon overdue interest at the rate borne by the Notes, 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

         (ii) all Events of Default, other than the non-payment of the principal
of Notes which have become due solely by such declaration of acceleration, have
been cured or waived as provided in Section 5.13.

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

         (d) Notwithstanding anything else contained herein, the Holders of the
Notes shall have the right to exercise their rights of conversion pursuant to
Article XIII immediately upon an Event of Default; however, if an Event of
Default occurs prior to one year from the date of original issuance of the
Notes, any conversion of such Notes will not be permitted until one year from
the date of original issuance of the Notes, and then will only be permitted if
such Event of Default has not been cured prior to one year from the date of
original issuance of the Notes.

         (e) Upon the consolidation with or merger into any other Person by the
Company or, the sale, lease, transfer, spin-off, or other disposal or
distribution of all or substantially all of the Company's properties and assets
to any Person, the Company shall deliver to the Trustee an Officers' Certificate
and an Opinion of Counsel, each stating whether such consolidation, merger,
sale, lease, transfer, spin-off, or other disposal or distribution causes an
Event of Default.

         SECTION 5.3 Collection of Indebtedness and Suits for Enforcement by
Trustee. If


                                      -27-




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

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

the Trustee is authorized to recover judgment as trustee on behalf of the
Holders against the Company for the whole amount then due and payable on such
Notes for principal (and premium, if any) and interest, and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal (and premium, if any) and on any overdue interest, at the rate borne
by the Notes, 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 an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders 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 5.4 Trustee May File Proofs of Claim. In case of any judicial
proceeding relative to the Company (or any other obligor upon the Notes), its
property or its creditors, the Trustee shall be entitled and empowered, by
intervention in such proceeding or otherwise,

                  (a) to file and prove a claim for the whole amount of
         principal and interest owing and unpaid in respect of the Notes and to
         file such other papers or documents as may be necessary or advisable in
         order to have the claims of the Trustee (including any claim for the
         reasonable compensation, expenses, disbursements and advances of the
         Trustee, its agents and counsel) and of the Holders allowed in such
         judicial proceeding, and

                  (b) to collect and receive any moneys or other property
         payable or deliverable on any such claim and to distribute 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 6.7.

         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 Notes 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

                                      -28-




the Trustee may, on behalf of the Holders, vote for the election of a trustee in
bankruptcy or similar official and be a member of a creditors' or other similar
committee.

         SECTION 5.5 Trustee May Enforce Claims Without Possession of Notes. All
rights of action and claims under this Indenture or the Notes may be prosecuted
and enforced by the Trustee without the possession of any of the Notes 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 the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, be for the ratable benefit of the Holders
of the Notes in respect of which such judgment has been recovered.

         SECTION 5.6 Application of Money Collected. Any money collected by the
Trustee pursuant to this Article V 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 premium, if any) or interest, upon
presentation of the Notes 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 6.7;

                  SECOND: subject to Article XII to the payment of the amounts
         then due and unpaid for first, interest on, and, second, for principal
         of (and premium, if any, on) the Notes 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 Notes for interest and principal (and premium, if any)
         respectively; and

                  THIRD: the balance, if any, to the Person or Persons entitled
         thereto, as their interest may appear or as a court of competent
         jurisdiction shall direct.

         SECTION 5.7 Limitation on Suits. No Holder of any Note 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

                  (a) such Holder has previously given written notice to the
         Trustee of a continuing Event of Default;

                  (b) the Holders of not less than 50% in principal amount of
         the Outstanding Notes shall have made written request to the Trustee to
         institute proceedings in respect of such Event of Default as Trustee on
         behalf of the Holders;

                  (c) 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;

                  (d) the Trustee for thirty (30) days after its receipt of such
         notice, request and offer of indemnity has failed to institute any such
         proceeding; and

                                      -29-




                  (e) no direction inconsistent with such written request has
         been given to the Trustee during such 30-day period by the Holders of a
         majority in principal amount of the Outstanding Notes;

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 of such
Holders.

         SECTION 5.8 Unconditional Right of Holders to Receive Principal,
Premium and Interest and to Convert. Notwithstanding any other provision in this
Indenture, the Holder of any Note shall have the right, which is absolute and
unconditional, to receive payment of the principal of (and premium, if any) and
(subject to Section 3.6) interest on such Note on the respective Stated
Maturities expressed in such Note (or, in the case of redemption, on the
Redemption Date) and to convert such Note in accordance with Article XIII and to
institute suit for the enforcement of any such payment and right to convert, and
such rights shall not be impaired without the consent of such Holder.

         SECTION 5.9 Restoration of Rights and Remedies. If the Trustee or any
Holder 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 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 Notes in the last paragraph of Section 3.5, no right or remedy
herein conferred upon or reserved to the Trustee or to the Holders 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 Notes 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 V or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders, as the case may be.

         SECTION 5.12 Control by Holders. The Holders of a majority in principal
amount of the Outstanding Notes shall have the right to direct the time, method
and place of conducting any

                                      -30-




proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee; provided that:

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

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

         (c) the Trustee may refuse to follow any direction which, in the
opinion of counsel to the Trustee, is unduly prejudicial to other Holders or
would subject the Trustee to personal liability.

         SECTION 5.13 Waiver of Past Defaults. The Holders of not less than a
majority in principal amount of the Outstanding Notes may on behalf of the
Holders of all the Notes waive any past default hereunder and its consequences,
except a default

         (a) in the payment of the principal of (or premium, if any) or interest
on any Note, or

         (b) in respect of a covenant or provision hereof which under Article IX
cannot be modified or amended without the consent of the Holder of each
Outstanding Note 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, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
provided, that this Section 5.14 shall not be deemed to authorize any court to
require such an undertaking or to make such an assessment in any suit instituted
by the Company or in any suit for the enforcement of the right to convert any
Note in accordance with Article XIII.

         SECTION 5.15 Waiver of Usury, 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 or take the
benefit or advantage of, any usury, 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 VI


                                      -31-




                                   The Trustee

         SECTION 6.1 Certain Duties and Responsibilities.

         (a)      Except during the continuance of an Event of Default,

                  (i) the Trustee undertakes to perform such duties and only
         such duties as are specifically set forth in this Indenture, and no
         implied covenants or obligations shall be read into this Indenture
         against the Trustee; and

                  (ii) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture; but in the case of any such certificates or opinions
         which by any provision hereof are specifically required to be furnished
         to the Trustee, the Trustee shall be under a duty to examine the same
         to determine whether or not they conform to the requirements of this
         Indenture.

         (b) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
his or her own affairs.

         (c) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that:

                  (i) this paragraph (c) shall not be construed to limit the
         effect of paragraph (a) of this Section;

                  (ii) the Trustee shall not be liable for any error of judgment
         made in good faith by a Responsible Officer, unless it shall be proved
         that the Trustee was negligent in ascertaining the pertinent facts;

                  (iii) the Trustee shall not be liable with respect to any
         action taken or omitted to be taken by it in good faith in accordance
         with the direction of the Holders of a majority in principal amount of
         the Outstanding Notes relating to the time, method and place of
         conducting any proceeding for any remedy available to the Trustee, or
         exercising any trust or power conferred upon the Trustee, under this
         Indenture; and

                  (iv) 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.


                                      -32-




         (d) 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 (as Trustee, Paying Agent, Authenticating
Agent or Note Registrar) shall be subject to the provisions of this Section.

         SECTION 6.2 Notice of Change in Control, Defaults and Events of
Default. Within sixty (60) days after the occurrence of any Change in Control,
Event of Default or default hereunder, the Trustee shall give the Holders, in
the manner provided in Section 1.6, notice of such Change in Control, Event of
Default or default hereunder actually known to a Responsible Officer of the
Trustee; provided, however, that in the case of any default of the character
specified in Section 5.1(a), no such notice to Holders shall be given until at

Default or default unless (a) the Trustee has received written notice thereof

would become, an Event of Default.

         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the

         Officers' Certificate or Opinion of Counsel;

                  (d) the Trustee may consult with counsel and the written
         advice of such counsel or any Opinion of Counsel shall be full and

         indemnity against the costs, expenses and liabilities which might be
         incurred by it in compliance with such request or direction;

                  (f) the Trustee shall not be bound to make any investigation

         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

         as it may see fit;

                  (g) the Trustee may execute any of the trusts or powers

         appointed with due care by it hereunder; and

                  (h) the Trustee shall not be liable for any action it takes or
         omits to take in good faith which it believes to be authorized or
         within its rights or power; provided, however, that the Trustee's
         conduct does not constitute willful misconduct or negligence.

         SECTION 6.4 Not Responsible for Recitals or Issuance of Notes. The
recitals contained herein and in the Notes, except the Trustee's certificates of
authentication, shall be taken as the statements of the Company, and neither the
Trustee nor any Authenticating Agent assumes any responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Notes. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company of Notes or the proceeds thereof.

         SECTION 6.5 May Hold Notes. The Trustee, any Authenticating Agent, any
Paying Agent, any Note Registrar or any other agent of the Company, in its
individual or any other capacity, may become the owner or pledgee of Notes and,
subject to Section 6.8 and Section 6.13, may otherwise deal with the Company
with the same rights it would have if it were not Trustee, Authenticating Agent,
Paying Agent, Note Registrar or such other agent.

         SECTION 6.6 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 6.7  Compensation and Reimbursement.  The Company agrees:

                  (a) 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);

                  (b) except as otherwise expressly provided herein, to
         reimburse the 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

                                      -34-




         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

                  (c) to indemnify the Trustee for, and to hold it harmless
         against, any loss, liability or expense incurred without negligence,
         willful misconduct or bad faith on its part, arising out of or in
         connection with the acceptance or administration of this trust,
         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. The Trustee shall notify the Company of
         any claim asserted against it for which it may seek indemnity. Failure
         by the Trustee to so notify the Company shall not relieve the Company
         of its obligations hereunder. The Company shall defend the claim and
         the Trustee may have separate counsel, the reasonable fees and expenses
         of which shall be paid by the Company.

                  All indemnifications and releases from liability granted
         hereunder to the Trustee shall extend to its officers, directors,
         employees, agents, successors and assigns.

                  When the Trustee incurs expenses or renders services after the
         occurrence of any Event of Default specified in Section 5.1, the
         expenses and the compensation for the services are intended to
         constitute expenses of administration under any bankruptcy, insolvency
         or similar laws.

                  The obligations of the Company under this Section shall
         survive the satisfaction and discharge of this Indenture.

         SECTION 6.8 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 6.9 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, authorized under such laws to
exercise corporate trust powers, which shall have (or, in the case of a
corporation included in a bank holding company system, the related bank holding
company shall have) a combined capital and surplus of at least U.S.$50,000,000,
subject to supervision or examination by federal or state authority, in good
standing and having an established place of business or agency in the states of
New York, New Jersey, Maryland or Pennsylvania. If such corporation or related
bank holding company 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 or related bank holding company 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.

         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 6.11.

         (b) The Trustee may resign at any time by giving written notice thereof
to the Company. If the instrument of acceptance by a successor Trustee required
by Section 6.11 shall not have been delivered to the Trustee within thirty (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.

         (c) The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the Outstanding Notes, delivered to the Trustee
and to the Company.

         (d) If at any time:

             (i) the Trustee shall fail to comply with Section 6.8 after
         written request therefor by the Company or by any Holder who has been
         a bona fide Holder of a Note for at least six months, or

             (ii) the Trustee shall cease to be eligible under Section 6.9
         and shall fail to resign after written request therefor by the Company
         or by any such Holder, or

                  (iii) 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 any 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 such case,
         (i) the Company by a Board Resolution may remove the Trustee, or (ii)
         subject to Section 5.14, any Holder who has been a bona fide Holder of
         a Note 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 and the appointment of a successor Trustee.

         (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee. If,
within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of the
Holders of a majority in principal amount of the Outstanding Notes 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 6.11, become the successor Trustee and to
that extent supersede the successor Trustee appointed by the Company. If no
successor Trustee shall have been so appointed by the Company or the Holders and
accepted appointment in the manner required by Section 6.11, any Holder who has
been a bona fide Holder of a Note 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.

                                      -36-




         (f) The Company shall give notice of each resignation and each removal
of the Trustee and each appointment of a successor Trustee to all Holders in the
manner provided in Section 1.6. Each notice shall include the name of the
successor Trustee and the address of its Corporate Trust Office.

         SECTION 6.11 Acceptance of Appointment by Successor. Every successor
Trustee appointed hereunder 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 any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; 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. Upon request of any such 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.

         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 corporate trust business
of the Trustee (including the trust created by this Indenture) 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 Notes 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 Notes so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Notes.

         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 Notes), 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
appoint an Authenticating Agent or Agents which shall be authorized to act on
behalf of the Trustee to authenticate Notes issued upon original issue and upon
exchange, registration of transfer, partial conversion or partial redemption,
pursuant to Section 3.3, and Notes 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 Notes 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

                                      -37-




Authenticating Agent and a certificate of authentication executed 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, authorized under such laws
to act as Authenticating Agent, which shall have (or, in the case of a
corporation included in a bank holding company system, the related bank holding
company shall have) a combined capital and surplus of not less than
U.S.$50,000,000 and shall be subject to supervision or examination by Federal or
State authority. 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 or related bank holding company 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 an Authenticating Agent (including the
authenticating agency contemplated by this Indenture), 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 the Authenticating Agent.

         An Authenticating Agent may 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 a notice of
resignation or upon such a 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 as their
names and addresses appear in the Note 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 payments, subject to the
provisions of Section 6.7.

         If an appointment is made pursuant to this Section, the Notes may have
endorsed thereon, in addition to the Trustee's certificate of authentication, an
alternative certificate of authentication in the following form:

         which is required under such Trust Indenture Act to be a part of and
         govern this Indenture, in any case to the extent necessary to qualify
         this Indenture under the Trust Indenture Act, or to make any other
         provisions with respect to matters or questions arising under this
         Indenture which shall not be inconsistent with the provisions of this
         Indenture; provided that such action pursuant to this clause shall not
         adversely affect the interests or legal rights of the Holders in any
         material respect.

         SECTION 9.2 Supplemental Indentures with Consent of Holders. With the
consent of the Holders of not less than a majority in principal amount of the

manner the rights of the Holders under this Indenture; provided, however, that
no such supplemental indenture shall, without the consent of the Holder of each
Outstanding Note affected thereby,

                  (a) change the Stated Maturity of the principal of, or any
         installment of interest on, any Note, or reduce the principal amount
         thereof or the rate of interest thereon or any premium payable upon the
         redemption thereof, or change the place of payment where, or the coin
         or currency in which, any Note or any premium or interest thereon is
         payable, or impair the right to institute suit for the enforcement of
         any such payment on or after the Stated Maturity thereof (or, in the
         case of redemption, on or after the Redemption Date), or adversely
         affect the right to convert any Note as provided in Article XIII
         (except as permitted by Section 9.1(d)), or modify the provisions of
         this Indenture with respect to the subordination of the Notes in a

         manner adverse to the Holders, or

                  (b) modify any of the provisions of this Section 9.2, Section
         5.13 or Section 10.8, except to increase any such percentage or to

         modified or waived without the consent of the Holder of each
         Outstanding Note affected thereby, or

                  (c) modify the obligation of the Company to maintain an office
         or agency in the states of New York or Pennsylvania pursuant to Section

         Outstanding Notes, the consent of whose Holders is required for any
         such supplemental indenture, or the consent of whose Holders is
         required for any waiver (of compliance with certain provisions of this
         Indenture or certain defaults hereunder and their consequences)
         provided for in this Indenture.

         It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

         SECTION 9.3 Execution of Supplemental Indentures. In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article IX or the modifications thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and (subject to Section 6.1
and Section 6.3) shall be fully protected in relying upon, an Opinion of Counsel
stating that the execution of such supplemental indenture is authorized or
permitted by this Indenture, complies with its terms and will, upon the
execution and delivery thereof, be valid and binding upon the Company in
accordance with its terms. The Trustee may, but shall not be obligated to, enter
into any such supplemental indenture which affects the Trustee's own rights,
duties or immunities under this Indenture or otherwise.


                                      -44-




         SECTION 9.4 Effect of Supplemental Indentures. Upon the execution of
any supplemental indenture under this Article, this Indenture shall be modified

thereafter authenticated and delivered hereunder shall be bound thereby.

         SECTION 9.5 Reference in Notes to Supplemental Indentures. Notes
authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article may, and shall if required by the Trustee, bear a
notation in form approved by the Trustee as to any maker provided for in such
supplemental indenture. If the Company shall so determine, new Notes so modified
as to conform, in the judgment of the Trustee and the Company, to any such
supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee in exchange for Outstanding Notes.


                                    ARTICLE X

                                    Covenants

         SECTION 10.1 Payment of Principal, Premium and Interest. The Company
will duly and punctually pay the principal of (and premium, if any) and interest
on the Notes in accordance with the terms of the Notes and this Indenture.

         SECTION 10.2 Maintenance of Office or Agency. The Company will maintain
in the states of New York or Pennsylvania an office or agency where Notes may be
presented or surrendered for payment, where Notes may be surrendered for
registration of transfer or exchange, where Notes may be surrendered for
conversion and where notices and demands to or upon the Company in respect of
the Notes and this Indenture may be served. The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency. If at any time the Company shall fail to maintain any such
required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

         The Company may also from time to time designate one or more other
offices or agencies where the Notes 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 the states of New
York or Pennsylvania for such purposes. The Company will give prompt written
notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency.

         SECTION 10.3 Money for Note Payments to Be Held in Trust. If the
Company shall at any time act as its own Paying Agent, it will, on or before
each due date of the principal of (and

                                      -45-




premium, if any) or interest on any of the Notes, segregate and hold in trust
for the benefit of the Persons entitled thereto a sum sufficient to pay the
principal (and premium, if any) 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 so to act.

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

         The Company will cause each Paying Agent other than 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 10.3,
that such Paying Agent will

                  (a) hold all sums held by it for the payment of the principal
         of, premium, if any, or interest on Notes in trust for the benefit of
         the Persons entitled thereto until such sums shall be paid to such
         Persons or otherwise disposed of as herein provided;

                  (b) give the Trustee notice of any default by the Company (or
         any other obligor upon the Notes) in the making of any payment of
         principal, premium, if any, or interest; and

                  (c) at any time during the continuance of any such default,
         upon the written request of the Trustee, forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent.

         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 premium, if
any) or interest on any Note and remaining unclaimed for two years after such
principal (and premium, if any) or interest has become due and payable shall be
paid to the Company on Company Request, or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Note shall 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 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 a newspaper published in the English

                                      -46-




language, customarily published on each Business Day and of general circulation
in the Philadelphia, notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than thirty (30) days from the
date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

         SECTION 10.4 Statement by Officers as to Default. The Company will, so
long as any of the Notes are outstanding, deliver to the Trustee forthwith upon
any officer becoming aware of (i) any Default, Event of Default or default in
the performance of any covenant, agreement or condition contained in this
Indenture or (ii) any Event of Default under any other mortgage, indenture or
instrument as that term is used in Section 5.1(d), an Officer's Certificate
specifying such Default, Event of Default or default and what action the Company
is taking or proposes to take with respect thereto and the status thereof.

         SECTION 10.5 Existence. Subject to Article VIII, the Company will do or
cause to be done all things necessary to preserve and keep in full force and
effect its existence, rights (charter and statutory) and franchises; provided,
however, that the Company shall not be required to preserve any such right or
franchise if the Board of Trustees shall determine that the preservation thereof
is no longer desirable in the conduct of the business of the Company and that
the loss thereof is not disadvantageous in any material respect to the Holders.

         SECTION 10.6 Maintenance of Properties. The Company will cause all
properties used or useful in the conduct of its business or the business of any
Subsidiary to be maintained and kept in good condition, repair and working order
and supplied with all necessary equipment and will cause to be made all
necessary repairs, renewals, replacements, betterments and improvements thereof,
all as in the judgment of the Company may be necessary so that the business
carried on in connection therewith may be properly and advantageously conducted
at all times; provided, however, that nothing in this Section shall prevent the
Company from discontinuing the operation or maintenance of any of such
properties, or disposing of any of them, if such discontinuance or disposition
is, in the judgment of the Company, desirable in the conduct of its business or
the business of any Subsidiary and not disadvantageous in any material respect
to the Holders.

         SECTION 10.7 Payment of Taxes and Other Claims. The Company will pay or
discharge or cause to be paid or discharged, before the same shall become
delinquent, (a) all taxes, assessments and governmental charges levied or
imposed upon the Company or any Subsidiary or upon the income, profits or
property of the Company or any Subsidiary, and (b) all lawful claims for labor,
materials and supplies which, if unpaid, might by law become a lien upon the
property of the Company or any Subsidiary; provided, however, that the Company
shall not be required to pay or discharge or cause to be paid or discharged any
such tax, assessment, charge or claim whose amount, applicability or validity is
being contested in good faith by appropriate proceedings.

         SECTION 10.8 Waiver of Certain Covenants. The Company may omit in any
particular instance to comply with any covenant or condition set forth in
Sections 10.5 to 10.7, inclusive, if before the time for such compliance the
Holders of at least a majority in principal amount of the

                                      -47-




Outstanding Notes shall, by Act of such Holders, either waive such compliance in
such instance or generally waive compliance with such covenant or condition, but
no such waiver shall extend to or affect such covenant or condition except to
the extent so expressly waived, and, until such waiver shall become effective,
the obligations of the Company and the duties of the Trustee in respect of any
such covenant or condition shall remain in full force and effect.




                                      -48-




                                   ARTICLE XI

                               Redemption of Notes

election of the Company, as a whole or from time to time in part, at any time on

Note hereinbefore set forth, together with accrued interest to (but not
including) the Redemption Date.

         SECTION 11.2 Applicability of Article. Redemption of Notes at the
election of the Company or otherwise, as permitted or required by any provision
of this Indenture, shall be made in accordance with such provision and this
Article XI.

         SECTION 11.3 Election to Redeem: Notice to Trustee. The election of the
Company to redeem any Notes pursuant to Section 11.1 shall be evidenced by a
Board Resolution. In case of any redemption at the election of the Company, the
Company shall, at least forty-five (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 and of the principal amount of Notes
to be redeemed.

         SECTION 11.4 Selection by Trustee of Notes to Be Redeemed. If less than
all the Notes are to be redeemed, the particular Notes to be redeemed shall be
selected not less than ten (10) days or more than thirty (30) days prior to the
Redemption Date by the Trustee (unless a shorter time period shall be
satisfactory to the Trustee), from the Outstanding Notes not previously called
for redemption, by such method as the Trustee shall deem fair and appropriate in
the circumstances.

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

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

         SECTION 11.5 Notice of Redemption. Notice of redemption shall be given
by first-class mail, postage prepaid, mailed not less than thirty (30) nor more
than sixty (60) days prior to the Redemption Date, to each Holder of Notes to be
redeemed, at his address appearing in the Note Register.

         All notices of redemption shall state:

                  (a) the Redemption Date,


                                      -49-




                  (b) the Redemption Price,

                  (c) if less than all the Outstanding Notes are to be redeemed,
         the identification (and, in the case of partial redemption of any
         Notes, the principal amounts) of the particular Notes to be redeemed,

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

                  (e) the conversion price, the date on which the right to
         convert the Notes to be redeemed will terminate and the place or places
         where such Notes may be surrendered for conversion, and

                  (f) the place or places where such Notes are to be surrendered
         for payment of the Redemption Price.

         Notice of redemption of Notes 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, and shall be irrevocable.

         SECTION 11.6 Deposit of Redemption Price. 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 10.3) 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 Notes which are to be redeemed on that date other
than any Notes called for redemption on that date which have been converted
prior to the date of such deposit.

         If any Note called for redemption is converted, any money deposited
with the Trustee or with any Paying Agent or so segregated and held in trust for
the redemption of such Note shall (subject to any right of the Holder of such
Note or any Predecessor Note to receive interest as provided in the last
paragraph of Section 3.6) be paid to the Company upon Company Request or, if
then held by the Company, shall be released from such trust.

         SECTION 11.7 Notes Payable on Redemption Date. Notice of redemption
having been given as aforesaid, the Notes 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 Notes shall cease to
bear or accrue any interest. Upon surrender of any such Note for redemption in
accordance with said notice, such Note shall be paid by the Company at the
Redemption Price, together with accrued interest to (but not including) the
Redemption Date.


                                      -50-




         If any Note called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid,
bear and accrue interest from the Redemption Date at the rate borne by the Note.

         SECTION 11.8 Notes Redeemed in Part. Any Note which is to be redeemed
only in part shall be surrendered at an office or agency of the Company
designated for that purpose pursuant to Section 10.2 (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-in-fact duly authorized in writing), and the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Note without service charge, a new Note or Notes, as requested by such
Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal amount of the Note so surrendered.

         SECTION 11.9 Conversion Arrangement on Call for Redemption. The Holders
of Notes shall have the right to exercise their rights of conversion, pursuant
to Article XIII, prior to any redemption by the Company. In connection with any
redemption of Notes, the Company may arrange for the purchase and conversion of
any Notes by an agreement with one or more investment bankers or other
purchasers to purchase such Notes by paying to the Trustee in trust for the
Holders, on or before the Redemption Date, an amount not less than the
applicable Redemption Price, together with interest accrued to the Redemption
Date, of such Notes. Notwithstanding anything to the contrary contained in this
Article XI, the obligation of the Company to pay the Redemption Price of such
Notes, together with interest accrued to, but excluding, the date fixed for
redemption, shall be deemed to be satisfied and discharged to the extent such
amount is so paid by such purchasers. If such an agreement is entered into, a
copy of which will be filed with the Trustee prior to the Redemption Date, any
Notes not duly surrendered for conversion by the Holders thereof may, at the
option of the Company, be deemed, to the fullest extent permitted by law,
acquired by such purchasers from such Holders and (notwithstanding anything to
the contrary contained in Article XIII) surrendered by such purchasers for
conversion, all as of immediately prior to the close of business on the
Redemption Date (and the right to convert any such Notes shall be deemed to have
been extended through such time), subject to payment of the above amount as
aforesaid. At the direction of the Company, the Trustee shall hold and dispose
of any such amount paid to it in the same manner as it would monies deposited
with it by the Company for the redemption of Notes. Without the Trustee's prior
written consent, no arrangement between the Company and such purchasers for the
purchase and conversion of any Notes shall increase or otherwise affect any of
the powers, duties, responsibilities or obligations of the Trustee as set forth
in this Indenture, and the Company agrees to indemnify the Trustee from, and
hold it harmless against, any loss, liability or expense arising out of or in
connection with any such arrangement for the purchase and conversion of any
Notes between the Company and such purchasers to which the Trustee has not
consented in writing, including the costs and expenses incurred by the Trustee
in the defense of any claim or liability arising out of or in connection with
the exercise or performance of any of its powers, duties, responsibilities or
obligations under this Indenture. Nothing in the preceding sentence shall be
deemed to limit the rights and protections afforded to the Trustee in Article VI
hereof, including, but not limited to, the right to indemnification pursuant to
Section 6.7.


                                      -51-




                                   ARTICLE XII

                             Subordination of Notes

         SECTION 12.1 Notes Subordinate to Senior Indebtedness. The Company
covenants and agrees, and each Holder of a Note, by his acceptance thereof,
likewise covenants and agrees, that, to the extent and in the manner hereinafter
set forth in this Article XII, the indebtedness represented by the Notes and the
payment of the principal of (and premium, if any) and interest on each and all
of the Notes and all obligations of the Company under this Indenture are hereby
expressly made subordinate and subject in right of payment to the prior payment
in full of all Senior Indebtedness.

         SECTION 12.2 Payment over of Proceeds upon Dissolution. In the event of
(a) any insolvency or bankruptcy case or proceeding, or any receivership,
liquidation, reorganization or other similar case or proceeding in connection
therewith, relative to the Company or to its creditors, as such, or to its
assets, or (b) any liquidation, dissolution or other winding up of the Company,
whether voluntary or involuntary and whether or not involving insolvency or
bankruptcy, or (c) any assignment for the benefit of creditors or any other
marshaling of assets and liabilities of the Company, then and in any such event
the holders of Senior Indebtedness shall be entitled to receive payment in full
of all amounts due or to become due on or in respect of all Senior Indebtedness,
or provision shall be made for such payment in cash or cash equivalents or
otherwise in a manner satisfactory to the holders of Senior Indebtedness, before
the Holders of the Notes are entitled to receive any payment on account of
principal of (or premium, if any) or interest on the Notes, and to that end the
holders of Senior Indebtedness shall be entitled to receive, for application to
the payment thereof, any payment or distribution of any kind or character,
whether in cash, property or securities, which may be payable or deliverable in
respect of the Notes in any such case, proceeding, dissolution, liquidation or
other winding up or event.

         In the event that, notwithstanding the foregoing provisions of this
Section, the Trustee or the Holder of any Note shall have received any payment
or distribution of assets of the Company prohibited by the foregoing paragraph
of any kind or character, whether in cash, property or securities, before all
Senior Indebtedness is paid in full or payment thereof provided for, and if such
fact shall, at or prior to the time of such payment or distribution, have been
made actually known to a Responsible Officer of the Trustee or, as the case may
be, such Holder, then and in such event such payment or distribution shall be
paid over or delivered forthwith to the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee, agent or other Person making payment
or distribution of assets of the Company for application to the payment of all
Senior Indebtedness remaining unpaid, to the extent necessary to pay all Senior
Indebtedness in full, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Indebtedness.

                                      -52-




         For purposes of this Article XII only, the words "cash, property or
securities" shall not be deemed to include shares of capital stock of the
Company as reorganized or readjusted, or securities of the Company or any other
corporation provided for by a plan of reorganization or readjustment which in
either case are subordinated in right of payment to all Senior Indebtedness
which may at the time be outstanding to substantially the same extent as, or to
a greater extent than, the Notes are so subordinated as provided in this Article
XII. The consolidation of the Company with, or the merger of the Company into,
another Person or the liquidation or dissolution of the Company following the
conveyance or transfer of its properties and assets substantially as an entirety
to another Person upon the terms and conditions set forth in Article VIII shall
not be deemed a dissolution, winding up, liquidation, reorganization, assignment
for the benefit of creditors or marshaling of assets and liabilities of the
Company for the purposes of this Section 12.2 if the Person formed by such
consolidation or into which the Company is merged or which acquires by
conveyance or transfer such properties and assets substantially as an entirety,
as the case may be, shall, as a part of such consolidation, merger, conveyance
or transfer, comply with the conditions set forth in Article VIII.

         SECTION 12.3  No Payment When Senior Indebtedness in Default.

         (a) In the event and during the continuation of any default in the
payment of principal of (or premium, if any) or interest on any Senior
Indebtedness beyond any applicable grace period with respect thereto (unless and
until such payment default shall have been cured or waived in writing by the
holders of such Senior Indebtedness), or in the event any judicial proceeding
shall be pending with respect to any such default, then no payment shall be made
by the Company on account of principal of (or premium, if any) or interest on
the Notes or on account of the purchase or other acquisition of Notes (including
pursuant to Articles XI and XIII); and

         (b) In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of any Note prohibited by the
foregoing provisions of this Section 12.3, and if such fact shall, at or prior
to the time of such payment, have been made actually known to a Responsible
Officer of the Trustee or, as the case may be, such Holder, then and in such
event such payment shall be paid over and delivered forthwith to the Company.

         The provisions of this Section 12.3 shall not apply to any payment with
respect to which Section 12.2 would be applicable.

         SECTION 12.4 Payment Permitted If No Default. Nothing contained in this
Article XII or elsewhere in this Indenture or in any of the Notes shall prevent
(a) the Company, at any time except during the pendency of any case, proceeding,
dissolution, liquidation or other winding up, assignment for the benefit of
creditors or other marshaling of assets and liabilities of the Company referred
to in Section 12.2 or under the conditions described in Section 12.3, from
making payments at any time of principal of (and premium, if any) or interest on
the Notes, or (b) the application by the Trustee of any money deposited with it
hereunder to the payment of or on account of the principal of (and premium, if
any) or interest on the Notes or the retention of such payment by the Holders,
if, at the time of such application by the Trustee, a Responsible

                                      -53-




Officer of the Trustee did not have actual knowledge that such payment would
have been prohibited by the provisions of this Article XII.

         SECTION 12.5 Subrogation to Rights of Holders of Senior Indebtedness.
Subject to the payment in full of all Senior Indebtedness, and until the Notes
are paid in full, the Holders of the Notes shall be subrogated (equally and
ratably with the holders of all indebtedness of the Company which by its express
terms is subordinated to indebtedness of the Company to substantially the same
extent as the Notes are subordinated and is entitled to like rights of
subrogation) to the rights of the holders of such Senior Indebtedness to receive
payments and distributions of cash, property and securities applicable to the
Senior Indebtedness to the extent that payments and distributions otherwise
payable to Holders of Notes have been applied to the payment of Senior
Indebtedness as provided by this Article XII. For purposes of such subrogation,
no payments or distributions to the holders of the Senior Indebtedness of any
cash, property or securities to which the Holders of the Notes or the Trustee
would be entitled, except for the provisions of this Article XII, and no
payments over pursuant to the provisions of this Article XII to the holders of
Senior Indebtedness by Holders of the Notes or the Trustee, shall, as among the
Company, its creditors other than holders of Senior Indebtedness and the Holders
of the Notes, be deemed to be a payment or distribution by the Company to or on
account of the Senior Indebtedness.

         SECTION 12.6 Provisions Solely to Define Relative Rights. The
provisions of this Article XII are and are intended solely for the purpose of
defining the relative rights of the Holders of the Notes on the one hand and the
holders of Senior Indebtedness on the other hand. Nothing contained in this
Article XII or elsewhere in this Indenture or in the Notes is intended to or
shall (a) impair, as among the Company, its creditors other than holders of
Senior Indebtedness and the Holders of the Notes, the obligation of the Company,
which is absolute and unconditional (and which, subject to the rights under this
Article XII of the holders of Senior Indebtedness, is intended to rank equally
with all other general obligations of the Company), to pay to the Holders of the
Notes the principal of (and premium, if any) and interest on the Notes as and
when the same shall become due and payable in accordance with their terms; or
(b) affect the relative rights against the Company of the Holders of the Notes
and creditors of the Company other than the holders of Senior Indebtedness; or
(c) prevent the Trustee or the Holder of any Note from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture, subject
to the rights, if any, under this Article XII of the holders of Senior
Indebtedness to receive cash, property and securities otherwise payable or
deliverable to the Trustee or such Holder.

         SECTION 12.7 Trustee to Effectuate Subordination. Each holder of a Note
by his acceptance thereof authorizes and directs the Trustee on his behalf to
take such action as may be necessary or appropriate to effectuate the
subordination provided in this Article XII and appoints the Trustee his
attorney-in-fact for any and all such purposes.

         SECTION 12.8 No Waiver of Subordination Provisions. No right of any
present or future holder of any Senior Indebtedness to enforce subordination as
herein provided shall at any time in any way be prejudiced or impaired by any
act or failure to act on the part of the Company

                                      -54-




or by any act or failure to act, in good faith, by any such holder, or by any
non-compliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness may, at any time and from time to time,
without the consent of or notice to the Trustee or the Holders of the Notes,
without incurring responsibility to the Holders of the Notes and without
impairing or releasing the subordination provided in this Article XII or the
obligations hereunder of the Holders of the Notes to the holders of Senior
Indebtedness, do any one or more of the following: (a) change the manner, place
or terms of payment or extend the time of payment of, or renew or alter, Senior
Indebtedness, or otherwise amend or supplement in any manner Senior Indebtedness
or any instrument evidencing the same or any agreement under which Senior
Indebtedness is outstanding; (b) sell, exchange, release or otherwise deal with
any property pledged, mortgaged or otherwise securing Senior Indebtedness; (c)
release any Person liable in any manner for the collection of Senior
Indebtedness; (d) exercise or refrain from exercising any rights against the
Company and any other Person; (e) apply any and all sums received from time to
time to the Senior Indebtedness.

         SECTION 12.9 Notice to Trustee. The Company shall give prompt written
notice to the Trustee of any fact known to the Company which would prohibit the
making of any payment to or by the Trustee in respect of the Notes.
Notwithstanding the provisions of this Article XII or any other provision of
this Indenture, the Trustee shall not be charged with knowledge of the existence
of any facts which would prohibit the making of any payment to or by the Trustee
in respect of the Notes, unless and until the Trustee shall have received
written notice thereof from the Company or a holder of Senior Indebtedness or
from any trustee therefor; and, prior to the receipt of any such written notice,
the Trustee, subject to the provisions of Section 6.1, shall be entitled in all
respects to assume that no such facts exist; provided, however, that if the
Trustee shall not have received the notice provided for in this Section 12.9 at
least two (2) Business Days prior to the date upon which by the terms hereof any
money may become payable for any purpose (including, without limitation, the
payment of the principal of (and premium, if any) or interest on any Note),
then, anything herein contained to the contrary notwithstanding, the Trustee
shall have full power and authority to receive such money and to apply the same
to the purpose for which such money was received and shall not be affected by
any notice to the contrary which may be received by it within two (2) Business
Days prior to such date.

         Subject to the provisions of Section 6.1, the Trustee shall be entitled
to rely on the delivery to it of a written notice by a Person representing
himself to be a holder of Senior Indebtedness (or a trustee therefor) to
establish that such notice has been given by a holder of Senior Indebtedness (or
a trustee therefor). In the event that the Trustee determines in good faith that
further evidence is required with respect to the right of any Person as a holder
of Senior Indebtedness to participate in any payment or distribution pursuant to
this Article XII, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such Person under this Article XII, and if such evidence is not furnished, the
Trustee may defer

                                      -55-




any payment to such Person pending judicial determination as to the right of
such Person to receive such payment.

         SECTION 12.10 Reliance on Judicial Order or Certificate of Liquidating
Agent. Upon any payment or distribution of assets of the Company referred to in
this Article XII, the Trustee, subject to the provisions of Section 6.1, and the
Holders of the Notes shall be entitled to rely upon any order or decree entered
by any court of competent jurisdiction in which such insolvency, bankruptcy,
receivership, liquidation, reorganization, dissolution, winding up or similar
case or proceeding is pending, or a certificate of the trustee in bankruptcy,
receiver, liquidating trustee, custodian, assignee for the benefit of creditors,
agent or other Person making such payment or distribution, delivered to the
Trustee or to the Holders of Notes, for the purpose of ascertaining the Persons
entitled to participate in such payment or distribution, the holders of the
Senior Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article XII.

         SECTION 12.11 Trustee Not Fiduciary for Holders of Senior Indebtedness.
The Trustee shall not be deemed to owe any fiduciary duty to the holders of
Senior Indebtedness and shall not be liable to any such holders if it shall in
good faith mistakenly pay over or distribute to Holders of Notes or to the
Company or to any other Person cash, property or securities to which any holders
of Senior Indebtedness shall be entitled by virtue of this Article XII or
otherwise.

         SECTION 12.12 Rights of Trustee as Holder of Senior Indebtedness:
Preservation of Trustee's Rights. The Trustee in its individual capacity shall
be entitled to all the rights set forth in this Article XII with respect to any
Senior Indebtedness which may at any time be held by it, to the same extent as
any other holder of Senior Indebtedness, and nothing in this Indenture shall
deprive the Trustee of any of its rights as such holder.

         Nothing in this Article XII shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 6.7.

         SECTION 12.13 Article Applicable to Paying Agents. In case at any time
any Paying Agent other than the Trustee shall have been appointed by the Company
and be then acting hereunder, the term "Trustee" as used in this Article XII
shall in such case (unless the context otherwise requires) be construed as
extending to and including such Paying Agent within its meaning as fully for all
intents and purposes as if such Paying Agent were named in this Article XII in
addition to or in place of the Trustee; provided, however, that Section 12.12
shall not apply to the Company or any Affiliate of the Company if it or such
Affiliate acts as Paying Agent.

         SECTION 12.14 Certain Conversions Deemed Payment. For the purposes of
this Article XII only, (a) the issuance and delivery of junior securities upon
conversion of Notes in accordance with Article XIII shall not be deemed to
constitute a payment or distribution on account of the principal of or premium
or interest on Notes or on account of the purchase or other acquisition of
Notes, and (b) the payment, issuance or delivery of cash, property or securities

                                      -56-




(other than junior securities) upon conversion of a Note shall be deemed to
constitute payment on account of the principal of such Note. For the purposes of
this Section 12.14, the term "junior securities" means (x) shares of any stock
of any class of the Company and (y) securities of the Company which are
subordinated in right of payment to the prior payment in full of all Senior
Indebtedness which may be outstanding at the time of issuance or delivery of
such securities to substantially the same extent as, or to a greater extent
than, the Notes are so subordinated as provided in this Article XII. Nothing
contained in this Article XII or elsewhere in this Indenture or in the Notes is
intended to or shall impair, as among the Company, its creditors other than
holders of Senior Indebtedness and the Holders of the Notes, the right, which is
absolute and unconditional, of the Holder of any Note to convert such Note in
accordance with Article XIII.


                                  ARTICLE XIII

                               Conversion of Notes

         SECTION 13.1 Conversion Privilege and Conversion Price. Subject to and
upon compliance with the provisions of this Article XIII, at the option of the
Holder thereof, any Note or any portion of the principal amount thereof may be
converted at the principal amount thereof, or of such portion thereof, into
fully paid and nonassessable Common Shares of the Company at any time after two
(2) years following the date of original issuance of Notes at the conversion
price, determined as hereinafter provided, in effect at the time of conversion,
or earlier upon a Change in Control (as defined in Section 8.1) or an Event of
Default (as defined in Section 5.1) but in no event prior to one year after the
date of original issuance. Such conversion right shall expire at the close of
business on the Business Day immediately preceding ______ __, 2008. In case a
Note or portion thereof is called for redemption at the election of the Company,
such conversion right in respect of the Note or portion so called shall expire
at the close of business, Philadelphia time, on the Business Day immediately
preceding the corresponding Redemption Date, unless the Company defaults in
making the payment due upon redemption.

         The price at which Common Shares shall be delivered upon conversion
(herein called the "conversion price") shall be initially U.S.$20.00 per Common
Share. The conversion price shall be adjusted in certain instances as provided
in Section 13.4.

         SECTION 13.2 Exercise of Conversion Privilege. In order to exercise the
conversion privilege, the Holder of any Note to be converted shall surrender
such Note, duly endorsed or assigned to the Company or in blank, at any office
or agency maintained by the Company pursuant to Section 10.2, accompanied by
written notice (as set forth in Section 2.5 herein) to the Company at such
office or agency that the Holder elects to convert such Note or, if less than
the entire principal amount thereof is to be converted, the portion thereof to
be converted.

         Except as described in the last paragraph of Section 3.6, no Holder of
Notes will be entitled upon conversion thereof to any payment or adjustment on
account of accrued and unpaid interest thereon (although such accrued and unpaid
interest will be deemed paid by the appropriate portion of the Common Shares
received by the holders upon such conversion) or on

                                      -57-




account of dividends on the shares of Common Shares issued in connection
therewith. Notes surrendered for conversion during the period from the close of
business on any Regular Record Date to the opening of business on the
corresponding Interest Payment Date (except Notes called for redemption on a
Redemption Date within such period between and including such Regular Record
Date and such Interest Payment Date) must be accompanied by payment to the
Company in New York Clearing House Funds or other funds acceptable to the
Company of an amount equal to the interest payable on such Interest Payment Date
on the principal amount converted.

         Notes shall be deemed to have been converted immediately prior to the
close of business on the day of surrender of such Notes for conversion in
accordance with the foregoing provisions, and at such time the rights of the
Holders of such Notes as Holders shall cease, and the Person or Persons entitled
to receive the Common Shares issuable upon conversion shall be treated for all
purposes as the record holder or holders of such Common Shares at such time. As
promptly as practicable on or after the conversion date, the Company shall issue
and shall deliver at such office or agency a certificate or certificates for the
number of Common Shares issuable upon conversion, together with payment in lieu
of any fraction of a share as provided in Section 13.3.

         In the case of any Note which is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Note or
Notes in aggregate principal amount equal to the unconverted portion of the
principal amount of such Note.

         SECTION 13.3 Fractions of Shares. No fractional Common Shares shall be
issued upon conversion of Notes. If more than one Note shall be surrendered for
conversion at one time by the same Holder, the number of full shares which shall
be issuable upon conversion thereof shall be computed on the basis of the
aggregate principal amount of the Notes (or specified portions thereof) so
surrendered. Instead of any fractional Common Shares which would otherwise be
issuable upon conversion of any Note or Notes (or specified portions thereof),
the Company shall pay a cash adjustment in respect of such fraction in an amount
equal to the same fraction of the Closing Price per Common Share at the close of
business on the day of conversion (or, if such day is not a Business Day, on the
Business Day immediately preceding such day) or, alternatively, the Company
shall round up to the next higher whole share.

         SECTION 13.4 Adjustment of Conversion Price.

         (a) In case the Company shall pay or make a dividend or other
distribution on its Common Shares exclusively in Common Shares or shall pay or
make a dividend or other distribution on any other class of capital stock of the
Company which dividend or distribution includes Common Shares, the conversion
price in effect at the opening of business on the day next following the date
fixed for the determination of shareholders entitled to receive such dividend or
other distribution shall be reduced by multiplying such conversion price by a
fraction of which the numerator shall be the number of Common Shares outstanding
at the close of business on the date fixed for such determination and the
denominator shall be the sum of such number of shares and the total number of
shares constituting such dividend or other distribution,

                                      -58-




such reduction to become effective immediately after the opening of business on
the day next following the date fixed for such determination. For the purposes
of this paragraph (a), the number of Common Shares at any time outstanding shall
not include shares held in the treasury of the Company but shall include shares
issuable in respect of scrip certificates issued in lieu of fractions of Common
Shares. The Company shall not pay any dividend or make any distribution on
Common Shares held in the treasury of the Company.

         (b) In case the Company shall pay or make a dividend or other
distribution on its Common Shares consisting exclusively of, or shall otherwise
issue to all holders of its Common Shares, rights, warrants or options entitling
the holders thereof to subscribe for or purchase Common Shares at a price per
share less than the current market price per share (determined as provided at
the end of this paragraph (b) of this Section 13.4) of the Common Shares on the
date fixed for the determination of shareholders entitled to receive such
rights, warrants or options, the conversion price in effect at the opening of
business on the day following the date fixed for such determination shall be
reduced by multiplying such conversion price by a fraction of which the
numerator shall be the number of Common Shares outstanding at the close of
business on the date fixed for such determination plus the number of Common
Shares which the aggregate of the offering price of the total number of Common
Shares so offered for subscription or purchase would purchase at such current
market price and the denominator shall be the number of Common Shares
outstanding at the close of business on the date fixed for such determination
plus the number of Common Shares so offered for subscription or purchase, such
reduction to become effective immediately after the opening of business on the
day following the date fixed for such determination. For the purposes of this
paragraph (b), the number of Common Shares at any time outstanding shall not
include shares held in the treasury of the Company but shall include shares
issuable in respect of scrip certificates issued in lieu of fractions of Common
Shares. The Company shall not issue any rights, warrants or options in respect
of Common Shares held in the treasury of the Company. For the purpose of any
computation under paragraph (b) of this Section 13.4, the current market price
per Common Share on any date in question shall be deemed to be the average of
the daily Closing Prices for the five (5) consecutive Trading Days selected by
the Company commencing not more than twenty (20) Trading Days before, and ending
not later than, the date in question.

         (c) In case outstanding Common Shares shall be subdivided into a
greater number of Common Shares, the conversion price in effect at the opening
of business on the day following the day upon which such subdivision becomes
effective shall be proportionately reduced, and, conversely, in case outstanding
Common Shares shall each be combined into a smaller number of Common Shares, the
conversion price in effect at the opening of business on the day following the
day upon which such combination becomes effective shall be proportionately
increased, such reduction or increase, as the case may be, to become effective
immediately after the opening of business on the day following the day upon
which such subdivision or combination becomes effective.

         (d) The Company may make such reductions in the conversion price, in
addition to those required by paragraphs (a) and (b) of this Section, as it
considers to be advisable in order

                                      -59-




that any event treated for Federal income tax purposes as a dividend of stock or
stock rights shall not be taxable to the recipients.

         (e) No adjustment in the conversion price shall be required unless such
adjustment would require an increase or decrease of at least 1% in the
conversion price; provided, however, that any adjustments which by reason of
this paragraph (5) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment.

         (f) In the event that the Company distributes rights or warrants (other
than those referred to in paragraph (b) above) pro rata to holders of Common
Shares, so long as any such rights or warrants have not expired or been redeemed
by the Company, the Company shall make proper provision so that the Holder of
any Note surrendered for conversion will be entitled to receive upon such
conversion, in addition to the Conversion Shares, a number of rights and
warrants to be determined as follows: (i) if such conversion occurs on or prior
to the date for the distribution to the holders of rights or warrants of
separate certificates evidencing such rights or warrants (the "Distribution
Date"), the same number of rights or warrants to which a holder of a number of
Common Shares equal to the number of Conversion Shares is entitled at the time
of such conversion in accordance with the terms and provisions of and applicable
to the rights or warrants, and (ii) if such conversion occurs after such
Distribution Date, the same number of rights or warrants to which a holder of
the number of Common Shares into which the principal amount of such Note so
converted was convertible immediately prior to such Distribution Date would have
been entitled on such Distribution Date in accordance with the terms and
provisions of and applicable to the rights or warrants.

         SECTION 13.5 Notice of Adjustments of Conversion Price. Whenever the
conversion price is adjusted as herein provided:

                  (a) the Company shall compute the adjusted conversion price in
         accordance with Section 13.4 and deliver to the Trustee an Officers'
         Certificate setting forth the adjusted conversion price and showing in
         reasonable detail the facts upon which such adjustment is based, and
         such Officers' Certificate shall forthwith be filed at each office or
         agency maintained for the purpose of conversion of Notes pursuant to
         Section 10.2; and

                  (b) a notice stating that the conversion price has been
         adjusted and setting forth the adjusted conversion price shall be
         mailed by the Company to all Holders at their last addresses as they
         shall appear in the Note Register promptly after the conversion price
         has been adjusted. Unless and until a Responsible Officer of the
         Trustee shall have received an Officers' Certificate setting forth an
         adjustment of the conversion price or stating that an action described
         in Section 13.6 has occurred, the Trustee shall not be deemed to have
         knowledge of such adjustment or action and may assume without inquiry
         (i) that the conversion price has not been adjusted, (ii) that the last
         conversion price of which the Trustee had knowledge remains in effect,
         and (iii) that no action described in Section 13.6 has occurred.


                                      -60-




         SECTION 13.6  Notice of Certain Corporate Action.  In case:

                  (a) the Company shall declare a dividend (or any other
         distribution) on its Common Shares payable otherwise than exclusively
         in cash; or

                  (b) the Company shall authorize the granting to the holders of
         its Common Shares of rights, warrants or options to subscribe for or
         purchase any shares of capital stock of any class or of any other
         rights (excluding employee stock options); or

                  (c) of any reclassification of the Common Shares of the
         Company (other than a subdivision or combination of its outstanding
         Common Shares), or of any consolidation or merger to which the Company
         is a party and for which approval of any shareholders of the Company is
         required, or of the sale or transfer of all or substantially all of the
         assets of the Company; or

                  (d) of the voluntary or involuntary dissolution, liquidation
         or winding up of the Company;

                  (e) the Company or any Subsidiary of the Company shall
         commence a tender or exchange offer for all or a portion of the
         Company's outstanding Common Shares (or shall amend any such tender or
         exchange offer);

then the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of Notes pursuant to Section 10.2, and shall cause to
be mailed to all Holders at their last addresses as they shall appear in the
Note Register, at least twenty (20) days (or ten (10) days in any case specified
in clause (a) or (b) above) prior to the applicable record, effective or
expiration date hereinafter specified, a notice (which shall be in the form of
an Officers' Certificate in the case of the notice delivered to the Trustee)
stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution or granting of rights, warrants or options, or, if a
record is not to be taken, the date as of which the holders of Common Shares of
record to be entitled to such dividend, distribution, rights, warrants or
options are to be determined, or (y) the date on which such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding up is
expected to become effective, and the date as of which it is expected that
holders of Common Shares of record shall be entitled to exchange their Common
Shares for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up, or (z) the date on which such tender offer commenced,
the date on which such tender offer is scheduled to expire unless extended, the
consideration offered and the other material terms thereof (or the material
terms of any amendment thereto).

         SECTION 13.7 Company to Reserve Common Shares. The Company shall at all
times reserve and keep available, free from preemptive rights, out of its
authorized but unissued Common Shares, solely for the purpose of effecting the
conversion of Notes, the whole number of Common Shares then issuable upon the
conversion in full of all outstanding Notes.


                                      -61-




         SECTION 13.8 Taxes on Conversions. The Company will pay any and all
excise and transfer taxes that may be payable in respect of the issue or
delivery of Common Shares on conversion of Notes pursuant hereto. The Company
shall not, however, be required to pay any tax which may be payable in respect
of any transfer involved in the issuance and delivery of Common Shares in a name
other than that of the Holder of the Note or Notes to be converted, and no such
issue or delivery shall be made unless and until the Person requesting such
issue has paid to the Company the amount of any such tax, or has established to
the satisfaction of the Company that such tax has been paid.

         SECTION 13.9 Covenant as to Common Shares. The Company covenants that
all Common Shares which may be issued upon conversion of Notes will upon issue
be newly issued (and not treasury shares) and be duly authorized, validly
issued, fully paid and nonassessable and, except as provided in Section 13.8,
the Company will pay all taxes, liens and charges with respect to the issue
thereof.

         SECTION 13.10 Cancellation of Converted Notes. All Notes delivered for
conversion shall be delivered to the Trustee to be canceled by or at the
direction of the Trustee, which shall dispose of the same as provided in Section
3.8.

         SECTION 13.11 Provisions in Case of Reclassification, Consolidation,
Merger or Sale of Assets. Unless the Notes were previously converted, during the
period from the date the Company resolves to take any action that would
constitute a Change in Control (as defined in Section 8.1) until five days prior
to the consummation of such Change in Control Transaction, the Holders of the
Notes shall have the right to make an election to convert all or any Notes in
accordance with Section 13.1 conditional upon approval of such Change in Control
by the holders entitled to vote on such matter, in which case, if such Change in
Control is approved, conversion of such Notes as to which a conditional election
has been made shall occur upon the later of (a) immediately prior to such Change
in Control, or (b) the date one year after the date of original issuance of the
Notes. The Company or the person formed by such consolidation or resulting from
such merger or which acquired such assets or which acquired the Company's
shares, as the case may be, shall execute and deliver to the Trustee a
supplemental indenture establishing such rights. Such supplemental indenture
shall provide for adjustments which, for events subsequent to the effective date
of such supplemental indenture, shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article. The above
provisions of this Section 13.11 shall similarly apply to successive
transactions of the foregoing type.


                                   ARTICLE XIV

                       Defeasance and Covenant Defeasance

         SECTION 14.1 Company's Option to Effect Defeasance or Covenant
Defeasance. The Company may at its option by Board Resolution, at any time,
elect to have either Section 14.2 or

                                      -62-




Section 14.3 applied to the Outstanding Notes upon compliance with the
conditions set forth below in this Article XIV.

         SECTION 14.2 Defeasance and Discharge. Upon the Company's exercise of
the option provided in Section 14.1 applicable to this Section, the Company and
the Trustee shall be deemed to have been discharged from their obligations with
respect to the Outstanding Notes (other than those specified below), and the
provisions of Article XII hereof shall cease to be effective, 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 Notes, the
Company and the Trustee shall be deemed to have satisfied all their other
obligations under such Notes and this Indenture insofar as such Notes 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 such Notes to receive, solely from the trust fund described in
Section 14.4 and as more fully set forth in such Section, payments in respect of
the principal of, premium, if any and interest on such Notes when such payments
are due, (b) the Company's obligations with respect to such Notes under Sections
3.4, 3.5, 3.6, 10.2, 10.3 and Article XIII, (c) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (d) this Article XIV. Subject
to compliance with this Article XIV, the Company may exercise its option under
this Section 14.2 notwithstanding the prior exercise of its option under Section
14.3.

         SECTION 14.3 Covenant Defeasance. Upon the Company's exercise of the
option provided in Section 14.1 applicable to this Section, (a) the Company
shall be released from its obligations under Section 10.6 and Section 10.7, (b)
the occurrence of an event specified in Section 5.1(d) shall not be deemed to be
an Event of Default and (c) the provisions of Article XII hereof shall cease to
be effective on and after the date the conditions set forth below are satisfied
(hereinafter, "covenant defeasance"). 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
Article, whether directly or indirectly by reason of any reference elsewhere
herein to any such Section or Article or by reason of any reference in any such
Section or Article to any other provision herein or in any other document, but
the remainder of this Indenture and such Notes shall be unaffected thereby.

         SECTION 14.4 Conditions to Defeasance or Covenant Defeasance.

         The following shall be the conditions to application of either Section
14.2 or Section 14.3 to the then Outstanding Notes:

                  (a) The Company shall irrevocably have deposited or caused to
         be deposited with the Trustee (or another trustee satisfying the
         requirements of Section 6.9 who shall agree to comply with the
         provisions of this Article XIV 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 such Notes, (i) money in an amount, or (ii) U.S. Government
         Obligations which through the scheduled payment of

                                      -63-




         principal and interest in accordance with their terms will provide, not
         later than one day before the due date of any payment, money in an
         amount, or (iii) a combination thereof, sufficient, in the written
         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, premium, if any, and each installment of interest on the
         Notes on the Stated Maturity of such principal or installment of
         interest in accordance with the terms of this Indenture and of such
         Notes. For this purpose, "U.S. Government Obligations" means securities
         that are (x) direct obligations of the United States of America 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 of America the payment
         of which is unconditionally guaranteed as a full faith and credit
         obligation by the United States of America, 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) 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;

                  (b) In the case of an election under Section 14.2, the Company
         shall have delivered to the Trustee an Opinion of Counsel stating that
         (i) the Company has received from, or there has been published by, the
         Internal Revenue Service a ruling, or (ii) since the date of this
         Indenture there has been a change in the applicable Federal income tax
         law, in either case to the effect that, and based thereon such opinion
         shall confirm that, the Holders of the Outstanding Notes will not
         recognize gain or loss for Federal income tax purposes as a result of
         such deposit, defeasance and discharge and will be subject to 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, defeasance and discharge
         had not occurred;

                  (c) In the case of an election under Section 14.3, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that the Holders of the Outstanding Notes will not recognize gain or
         loss for Federal income tax purposes as a result of such deposit and
         covenant defeasance and will be subject to 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;

                  (d) The Company shall have delivered to the Trustee an
         Officers' Certificate to the effect that the Notes, if then listed on
         any securities exchange, will not be delisted as a result of such
         deposit;


                                      -64-




                  (e) Such defeasance or covenant defeasance shall not cause the
         Trustee to have a conflicting interest as defined in Section 6.8;

                  (f) At the time of such deposit: (i) no default in the payment
         of all or a portion of principal of (or premium, if any) or interest on
         or other obligations in respect of any Senior Indebtedness shall have
         occurred and be continuing, and no event of default with respect to any
         Senior Indebtedness shall have occurred and be continuing and shall
         have resulted in such Senior Indebtedness becoming or being declared
         due and payable prior to the date on which it would otherwise have
         become due and payable and (ii) no other event with respect to any
         Senior Indebtedness shall have occurred and be continuing permitting
         (after notice or the lapse of time, or both) the holders of such Senior
         Indebtedness (or a trustee on behalf of the holders thereof) to declare
         such Senior Indebtedness due and payable prior to the date on which it
         would otherwise have become due and payable, or, in the case of either
         Clause (a) or Clause (b) above, each such default or event of default
         shall have been cured or waived or shall have ceased to exist;

                  (g) No Event of Default or event which with notice or lapse of
         time or both would become an Event of Default shall have occurred and
         be continuing on the date of such deposit or, insofar as subsections
         5.1(e) and (f) 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);

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

                  (i) 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 14.2 or the covenant defeasance under Section 14.3 (as
         the case may be) have been complied with; and

                  (j) 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 14.5 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 10.3, 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 14.5, the "Trustee") pursuant
to Section 14.4 in respect of the Notes shall be held in trust and applied by
the Trustee, in accordance with the provisions of such Notes 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 such Notes, of all sums due and to become due

                                                       -65-




thereon in respect of principal, premium, if any, and interest. Money so held in
trust shall not be subject to the provisions of Article XII.

         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 14.4 or the principal and interest received other
than any such tax, fee or other charge which by law is for the account of the
Holders of the Outstanding Notes.

         Anything in this Article XIV 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 14.4 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 14.6 Reinstatement. If the Trustee or the Paying Agent is
unable to apply any money in accordance with Section 14.2 or 14.3 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 Notes shall be revived and reinstated
as though no deposit had occurred pursuant to this Article XIV until such time
as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 14.2 or 14.3; provided, however, that if the Company
makes any payment of principal of, premium, if any, or interest on any Note
following the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Notes to receive such payment from the
money held by the Trustee or the Paying Agent.


                                   ARTICLE XV

                                    Immunity

         SECTION 15.1 Personal Immunity of Incorporators, Shareholders,
Directors and Officers. No recourse for the payment of the principal of or
interest on the Notes, and no recourse under or upon any obligation, covenant or
agreement contained in this Indenture or in any indenture supplemental hereto,
or in the Notes, or because of any indebtedness evidenced thereby, shall be had
against any incorporator, or against any past, present or future shareholder,
officer, director, trustee, partner, member, as such, of the Company or any
successor entity, either directly or through the Company or any successor
entity, under any rule of law, statute or constitutional provision or by the
enforcement of any assessment or by any legal or equitable proceeding or
otherwise, all such liability being expressly waived and released by the
acceptance of the Notes by the Holders thereof and as part of the consideration
for the issue of the Notes. Each and every Holder of the Notes, by receiving and
holding the same, agrees to the provisions of this Section 15.1 and waives and
releases any and all such recourse, claim and liability.


                                      -66-




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



                                      -67-




         IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be
duly executed, and their respective corporate seals to be hereunto affixed, all
as of the day and year first above written.
