                          PETERSBURG LONG DISTANCE INC.

                    9% CONVERTIBLE SUBORDINATED NOTE DUE 2006


         1.       Indenture.

                  This Note is one of a duly authorized issue of debt securities
of Petersburg Long Distance Inc., an Ontario corporation (such corporation, and
its successors and assigns under the Indenture hereinafter referred to, being
herein called the "Company"), designated as its "9% Convertible Subordinated
Notes due 2006" (herein called the "Notes") limited in aggregate principal
amount at Stated Maturity to $26,500,000, issued under an indenture dated as of
May 31, 1996 (as amended or supplemented from time to time, the "Indenture")
among the Company, the corporations acting as guarantors and named therein (the
"Guarantors") and The Bank of New York, as trustee (the "Trustee," which term
includes any successor Trustee under the Indenture), to which Indenture
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Guarantors, the
Trustee and each Holder of Notes and of the terms upon which the Notes are, and
are to be, authenticated and delivered. The summary of the terms of this Note
contained herein does not purport to be complete and is qualified by reference
to the Indenture. All terms used in this Note which are not defined herein shall
have the meanings assigned to them in the Indenture.

                  The Indenture imposes certain limitations on the ability of
the Company and its Restricted Subsidiaries to make Asset Sales. The Indenture
also imposes limitations on the ability of the Company to consolidate or merge
with or into any other Person or permit any other Person to merge with or into
the Company, or sell, convey, assign, transfer, lease or otherwise dispose of
all or substantially all of the Property of the Company to any other Person. The
Indenture does not contain any restrictions on the incurrence of indebtedness,
the creation of liens or the payment of dividends or the making of
distributions, investments or certain other restricted payments or any financial
covenants.


         2.       Principal and Interest.

                  The Company promises to pay the principal amount set forth on
Schedule A of this Note to the Holder hereof on June 1, 2006.

                  This Note will commence to accrue interest from the Issue Date
at a rate computed as if this Note had been issued bearing interest at the rate
of 9% per annum on May 31, 1996 (being the rate of 9.5858% per annum for the
period from the Issue Date through November 30, 1996), and this Note will bear
interest at the rate of 9% per annum from December 1, 1996. The Company shall
pay such interest from the Issue Date or from the most recent Interest Payment
Date thereafter to which interest has been paid or duly provided for
semi-annually on June 1 and December 1 of each year, commencing on December 1,
1996, in cash, to the Holder hereof until the principal amount hereof is paid or
made available for payment. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, subject to certain exceptions
provided in the Indenture, be paid to the Person in whose name this Note (or the
Note in exchange or substitution for which this Note was issued) is registered
at the close of business on the Record Date for interest payable on such
Interest Date. The Record Date 


                                      -4-
<PAGE>   5
for any Interest Payment Date is the close of business on May 15 or November 15,
as the case may be, whether or not a Business Day, immediately preceding the
Interest Payment Date on which such interest is payable. Any such interest not
so punctually paid or duly provided for ("Defaulted Interest") shall forthwith
cease to be payable to the Holder on such Record Date and shall be paid as
provided in Section 2.11 of the Indenture. Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

                  Each payment of interest in respect of an Interest Payment
Date will include interest (including Additional Amounts (as hereinafter
defined), if any, and Special Interest (as hereinafter defined), if any),
accrued through the day before such Interest Payment Date. If an Interest
Payment Date falls on a day that is not a Business Day, the interest payment to
be made on such Interest Payment Date will be made on the next succeeding
Business Day with the same force and effect as if made on such Interest Payment
Date, and no additional interest will accrue as a result of such delayed
payment.

                  To the extent lawful, the Company shall pay interest on (i)
any overdue principal of (and premium, if any, on) this Note, at the interest
rate borne on this Note, plus 1% per annum, and (ii) Defaulted Interest (without
regard to any applicable grace period), at the same rate. The Company's
obligation pursuant to the previous sentence shall apply whether such overdue
amount is due at its Stated Maturity, as a result of the Company's obligations
pursuant to Section 3.6, Section 4.7, Section 4.8 or Section 4.14 of the
Indenture, or otherwise.

         3.       Additional Amounts.

                  Except to the extent required by law, any and all payments of,
or in respect of, this Note shall be made free and clear of and without
deduction for or on account of any and all present or future taxes, levies,
imposts, deductions, charges or withholdings and all liabilities with respect
thereto imposed by Canada, the Russian Federation, Cyprus or any other
jurisdiction with which the Company or any Guarantor has some connection
(including any jurisdiction (other than the United States of America) from or
through which payments under the Notes are made) or any political subdivision of
or any taxing authority in any such jurisdiction ("Canadian Taxes," "Russian
Taxes," "Cypriot Taxes" or "Other Taxes," respectively). If the Company or any
Guarantor shall be required by law to withhold or deduct any Canadian Taxes,
Russian Taxes, Cypriot Taxes or Other Taxes from or in respect of any sum
payable under this Note or pursuant to a Guarantee, the sum payable by the
Company or such Guarantor, as the case may be, thereunder shall be increased by
the amount ("Additional Amounts") necessary so that after making all required
withholdings and deductions, the Holder of this Note shall receive an amount
equal to the sum that it would have received had no such withholdings and
deductions been made; provided that any such sum shall not be paid in respect of
any Canadian Taxes, Russian Taxes, Cypriot Taxes or Other Taxes to the Holder of
this Note (an "Excluded Holder") (i) resulting from the beneficial owner of this
Note carrying on business or being deemed to carry on business in or through a
permanent establishment or fixed base in the relevant taxing jurisdiction or any
political subdivision thereof or having any other connection with the relevant
taxing jurisdiction or any political subdivision thereof or any taxing authority
therein other than the mere holding or owning of this Note, being a beneficiary
of the Guarantees, the receipt of any income or payments in respect of this Note
or the Guarantees or the enforcement of this Note or the Guarantees, (ii)
resulting from the Company or any Guarantor not dealing at arm's length (within
the meaning of the Income Tax Act (Canada)), with the Holder of this Note at the
time of such payment or at the time the amount of such payment is deemed to have
been paid or credited or (iii) that would not have been imposed but for the
presentation (where presentation is required) of this Note for payment more than
180 days after the date such payment became due and payable or was duly provided


                                      -5-
<PAGE>   6
for, whichever occurs later. The Company or the Guarantors, as applicable, will
also (i) make such withholding or deduction and (ii) remit the full amount
deducted or withheld to the relevant authority in accordance with applicable
law, and, in any such case, the Company will furnish to each Holder on whose
behalf an amount was so remitted, within 30 calendar days after the date the
payment of any Canadian Taxes, Russian Taxes, Cypriot Taxes or Other Taxes is
due pursuant to applicable law, certified copies of tax receipts evidencing such
payment by the Company or the Guarantors, as applicable. The Company will, upon
written request of each Holder (other than an Excluded Holder), reimburse each
such Holder for the amount of (i) any Canadian Taxes, Russian Taxes, Cypriot
Taxes or Other Taxes so levied or imposed and paid by such Holder as a result of
payments made under or with respect to any Notes, and (ii) any Canadian Taxes,
Russian Taxes, Cypriot Taxes or Other Taxes so levied or imposed with respect to
any reimbursement under the foregoing clause (i) so that the net amount received
by such Holder (net of payments made under or with respect to such Notes or the
Guarantees) after such reimbursement will not be less than the net amount the
Holder hereof would have received if Canadian Taxes, Russian Taxes, Cypriot
Taxes or Other Taxes on such reimbursement had not been imposed.

                  In addition, the Company or the Guarantors will pay any stamp,
issue, registration, documentary or other similar taxes and duties, including
interest and penalties, in respect of the creation, issue and offering of the
Notes payable in Canada, the United States, the Russian Federation or Cyprus or
any political subdivision thereof or taxing authority of or in the foregoing.
The Company and the Guarantors will also pay and indemnify the Holders from and
against all court fees and taxes or other taxes and duties, including interest
and penalties, paid by any of them in any jurisdiction in connection with any
action permitted to be taken by the Trustee or the Holders to create the Liens
on the Collateral and to enforce the obligations of the Company or the
Guarantors under the Notes, the Indenture, the Guarantees, the Collateral
Documents or the Senior Note Collateral Documents.

         4.       Special Interest.

                  Special interest means such additional interest as is set
forth in subparagraphs (a) and (b) below.

                  (a) The Holder of this Note is entitled to the benefits of the
Registration Rights Agreement, dated as of May 31, 1996, between the Company and
the Initial Purchasers (the "Registration Agreement"), which agreement is
attached to the Indenture as Exhibit C thereto. In the event that either (a) the
Convertible Note Shelf Registration Statement (as such term is defined in the
Registration Agreement) is not filed with the Securities and Exchange Commission
(the "Commission") on or prior to the 45th day following the Issue Date, (b) the
Shelf Registration Statement is not declared effective by the Commission on or
prior to the 120th day following the Issue Date or (c) any such Shelf
Registration Statement is filed and declared effective but shall thereafter
cease to be effective or fail to be usable for its intended purposes, without
being succeeded by a post-effective amendment to such Shelf Registration
Statement that cures such failure and that is itself declared effective, for a
period of more than 30 consecutive days, interest shall accrue on this Note (in
addition to any accrual of stated interest on this Note) from and including the
next day following each of (i) such 45-day period in the case of clause (a)
above, (ii) such 120-day period in the case of clause (b) above, (iii) such
30-day period in the case of clause (c) above (each such event referred to in
clauses (i) through (iii), a "Registration Default"). In each case following the
occurrence of a Registration Default, such additional interest (the "Special
Interest") will be payable to the Holder hereof during the first 90-day period
immediately following the occurrence of such Registration Default in cash
semiannually in arrears on each Interest Payment Date, at a rate equal to $0.01
per week per $1,000 principal amount of this Note. The Special Interest payable


                                      -6-
<PAGE>   7
to the Holder of this Note shall increase by an additional $0.01 per week per
$1,000 principal amount of this Note for each 90-day period up to a maximum of
$0.50 per week per $1,000 of this Note. Upon (w) the filing of the Shelf
Registration Statement after the 45-day period described in clause (a) above,
(x) the effectiveness of a Shelf Registration Statement after the 120-day period
described in clause (b) above, or (y) the effectiveness of an applicable
Registration Statement after the 30-day period described in clause (c) above,
the Special Interest payable on this Note, with respect to such clause (a), (b)
or (c), as the case may be, from the date of such filing, effectiveness or
consummation, as the case may be, shall cease to accrue and all accrued and
unpaid Special Interest as of the occurrence of (w), (x) or (y) shall be paid to
the Holder hereof on the next Interest Payment Date with respect thereto.
Following the occurrence of (w), (x) and (y) above, the interest terms of this
Note shall revert to the original terms set forth above subject to paragraph (b)
below.

                  (b) In the event of the failure of the Company to procure, on
or before July 12, 1996, a recognized financial institution with capital of not
less than $10,000,000 organized under the laws of the Republic of Ireland which
the Trustee may lawfully appoint as a Qualified Foreign Collateral Agent (as
defined in Section 7.3 of the Indenture) (the "Procurement") with respect to
Technocom Preferred Stock, any payments thereon and any property substituted
therefor (the "Subject Collateral") pursuant to an agreement under which such
Qualified Foreign Collateral Agent will agree not to resign without the
contemporaneous appointment of a successor Qualified Foreign Collateral Agent
(the "Prescribed Agreement"), then, commencing on July 12, 1996, the Company
shall pay to each Holder of the Notes additional Special Interest in an amount
equal to 1% per annum on the principal amount of such Holder's Notes, accruing
for each day until the Procurement is made or Technocom or a successor is
reorganized under the laws of Cyprus and a successor Qualified Foreign
Collateral Agent has been appointed in respect of the Subject Collateral (the
"Reorganization") under a Prescribed Agreement. Such Special Interest shall be
payable in cash semi-annually in arrears at the times and in the manner provided
for in the Indenture. Such Special Interest shall cease to accrue upon the
Procurement or the Reorganization taking place and all accrued and unpaid
Special Interest shall be paid to each Holder of the Notes on the next Interest
Payment Date with respect thereto. Any Special Interest payable pursuant to this
paragraph 4(b) shall be in addition to any Special Interest that may be payable
pursuant to paragraph 4(a) above.

                  Except as expressly provided in this paragraph 4, Special
Interest shall be treated as interest and any date on which Special Interest is
due and payable shall be treated as Interest Payment Date, for all purposes
under this Note and the Indenture.

         5.       Method of Payment.

                  The Company, through the Paying Agent, shall pay interest on
this Note to the registered Holder of this Note, as provided above. The Holder
must surrender this Note to a Paying Agent to collect principal payments. The
Company will pay principal and interest in money of the United States of America
that at the time of payment is legal tender for payment of all debts public and
private. Principal and interest will be payable at the office of the Paying
Agent but, at the option of the Company, interest may be paid by check mailed to
the registered Holders at their registered addresses.


                                      -7-

         6.       Paying Agent and Registrar.

                  Initially, the Trustee will act as Paying Agent and Registrar
under the Indenture. The Company may, upon written notice to the Trustee,
appoint and change any Paying Agent or Registrar. The Company or any of its
subsidiaries may act as Paying Agent or Registrar.

         7.       Optional Redemption.

                  Except as set forth in the following paragraph, the Notes may
not be redeemed prior to June 1, 2000. During the period from June 1, 2000 to
May 31, 2002, the Company may redeem all but not less than all of the Notes if
the Closing Price (as defined in the Indenture) of the Common Stock (as defined
in the Indenture) equals or exceeds 150% of the conversion price of the Notes
for a period of 30 consecutive days, at a redemption price equal to 100% of the
principal thereof, plus accrued and unpaid interest, if any, Additional Amounts,
if any, and Special Interest, if any, to the applicable Redemption Date, and any
other amount due in respect thereof (but not including any amount on any Reset
Penalty (as defined below)). Thereafter, the Notes will be subject to redemption
at the option of the Company, in whole or in part, upon not less than 30
calendar days' nor more than 60 calendar days' notice, at a redemption price
equal to 100% of the principal amount thereof, plus accrued and unpaid interest
thereon (if any), Additional Amounts (if any) and Special Interest (if any) to
the applicable Redemption Date, and any other amounts due in respect thereof. No
amount shall be paid in respect of any Reset Penalty upon any redemption, offer
to purchase or other acquisition except in respect of a record date for the
Reset Penalty which has passed.

                  The Notes may be redeemed, at the option of the Company, in
whole but not in part, upon not less than 30 or more than 60 calendar days'
notice to the Holders in accordance with the terms of the Indenture, at a
redemption price equal to the principal amount thereof, plus accrued and unpaid
interest, if any (including Additional Amounts, if any, and Special Interest, if
any), to the applicable Redemption Date (subject to the right of Holders of
record on the relevant Record Date to receive interest (including Additional
Amounts, if any, and Special Interest, if any) due on the Interest Payment Date
that is on or prior to the Redemption Date) and any other amounts due if, as a
result of any change in or amendment to the laws or the regulations or rulings
promulgated thereunder of Canada, Cyprus, the Russian Federation or any other
jurisdiction with which the Company or any Guarantor has any connection (other
than a connection arising as a result of a continuance or a merger or
consolidation of the Company with or into a newly formed corporation solely for
the purpose of moving the Company's domicile out of Canada) or any political
subdivision thereof or any authority thereof or having power to tax therein, or
any change in the application or official interpretation of such laws or
regulations, or any change in administrative policy or assessing practice of the
applicable taxing authority, which change or amendment becomes effective on or
after May 24, 1996, the Company or the Guarantors (if the Guarantees are called)
are or would be required on the next succeeding Interest Payment Date to pay
Additional Amounts with respect to the Notes or the Guarantees and the payment
of such Additional Amounts cannot be avoided by the use of any reasonable
measures available to the Company or the Guarantors, as the case may be. The
Company will also pay to holders on the Redemption Date any Additional Amounts
payable in respect of the period ending on the Redemption Date. Prior to the
publication of any notice of redemption pursuant to this provision, which in no
event will be given earlier than 90 days prior to the earliest date on which the
Company or the Guarantors, as the case may be, would be required to pay such
Additional Amounts were a payment in respect of the Notes then due, the Company
shall deliver to the Trustee (i) an Officers' Certificate stating that the
obligation to pay such Additional Amounts cannot be avoided by the Company or
the Guarantors, as the case may be, taking 


                                      -8-
<PAGE>   9
reasonable measures and (ii) an Opinion of Counsel, independent of the Company
and the Guarantors and approved by the Trustee, to the effect that the Company
or the Guarantors have or will become obligated to pay such Additional Amounts
as a result of such change or amendment. Such notice, once delivered by the
Company to the Trustee, will be irrevocable. The Trustee shall accept such
Officers' Certificate and Opinion of Counsel as sufficient evidence of the
satisfaction of the condition precedent set forth in clauses (i) and (ii) above,
in which event it shall be conclusive and binding on the Holders.

         8.       Notice of Redemption.

                  At least 30 calendar days but not more than 60 calendar days
before a Redemption Date, the Company will send a notice of redemption, first
class mail, postage prepaid, to Holders of Notes to be redeemed at the addresses
of such Holders as they appear in the Note Register.

                  If less than all of the Notes are to be redeemed at any time,
the Notes to be redeemed will be chosen by the Trustee in accordance with the
Indenture. If any Note is redeemed subsequent to a Record Date with respect to
any Interest Payment Date specified above and on or prior to such Interest
Payment Date, then any accrued interest (including Additional Amounts, if any,
and Special Interest, if any) will be paid on such Interest Payment Date to the
Holder of the Note on such Record Date. If money in an amount sufficient to pay
the Redemption Price of all Notes (or portions thereof) to be redeemed on the
Redemption Date is deposited with the Paying Agent on or before the applicable
Redemption Date and certain other conditions are satisfied, interest (including
Additional Amounts, if any, and Special Interest, if any) on the Notes to be
redeemed on the applicable Redemption Date will cease to accrue.

                  The Notes are not subject to any sinking fund.

         9.       Repurchase at the Option of Holders upon Change of Control.

                  Upon the occurrence of a Change of Control, each Holder of
Notes shall have the right to require the Company to purchase such Holder's
Notes, in whole or in part in a principal amount that is an integral multiple of
$1,000, pursuant to a Change of Control Offer, at a purchase price in cash equal
to 101% of the principal amount thereof on any Change of Control Payment Date,
plus accrued and unpaid interest, if any, Additional Amounts, if any, and
Special Interest, if any, thereon to the Change of Control Payment Date.

                  Within 30 calendar days following any Change of Control, the
Company shall send, or cause to be sent, by first-class mail, postage prepaid, a
notice regarding the Change of Control Offer to each Holder of Notes. The holder
of this Note may elect to have this Note or a portion hereof in an authorized
denomination purchased by completing the form entitled "Option of Holder to
Require Purchase" appearing below and tendering this Note pursuant to the Change
of Control Offer. Unless the Company defaults in the payment of the Change of
Control Purchase Price with respect thereto, all Notes or portions thereof
accepted for payment pursuant to the Change of Control Offer will cease to
accrue interest and Additional Amounts, if any, and Special Interest, if any,
from and after the Change of Control Payment Date.

                  Subject to the limitations set forth in the following
paragraph and the Indenture, if at any time the Company or any Restricted
Subsidiary engages in any Asset Sale, as a result of which the aggregate amount
of Excess Proceeds exceeds $5,000,000, the Company shall, within 30 calendar
days of the date the amount of Excess Proceeds exceeds $5,000,000, use the
then-existing Excess Proceeds to make an offer to purchase from all Holders, on
a pro rata basis, Notes in an aggregate principal amount equal to the maximum
principal amount that may be purchased out of the then-existing Excess Proceeds,
at a purchase price in cash equal to 100% of the principal amount thereof on any
Asset Sale Payment Date, plus accrued and unpaid interest thereon, if any, and
Additional Amounts, if any, and Special Interest, if any, to the Asset Sale
Payment Date, provided that Excess Proceeds attributable to assets not
constituting Collateral (as defined in the Indenture) must be used first to make
an Asset Sale Offer pursuant to the Senior Note Indenture (as defined in the
Indenture) unless the Senior Notes are no longer outstanding and the Senior Note
Indenture has been satisfied and discharged, and then to make an Asset Sale
Offer for the Notes, if there remain Excess Proceeds after the Asset Sale Offer
for the Senior Notes has been completed. Upon completion of an Asset Sale Offer
(including payment of the Offer Purchase Price for accepted Notes), any surplus
Excess Proceeds that were the subject of such offer shall cease to be Excess
Proceeds, and the Company may then use such amounts for general corporate
purposes.

                  Notwithstanding the paragraph above, the Company will not be
obligated to repurchase Notes in connection with an Asset Sale Offer
representing in the aggregate more than 25% of the original aggregate principal
amount of the Notes (which original aggregate principal amount shall for these
purposes be $26,500,000, without any adjustment whatsoever) prior to the date
following the Five Year Date, and the original aggregate principal amount of
Notes repurchased in connection with any Asset Sale Offer having a purchase date
prior to the date following the Five Year Date shall represent no more than 25%
of the original aggregate principal amount of the Notes less the original
aggregate principal amount of Notes purchased pursuant to Asset Sale Offers
relating to all prior Asset Sales. To the extent that the amount of Excess
Proceeds exceeds the amount of Notes purchased because of the limitation imposed
by the immediately preceding sentence (the amount of such excess being the
"Aggregate Unused Proceeds"), such Aggregate Unused Proceeds shall constitute
Excess Proceeds for purposes of the first Asset Sale Offer that is made after
the Five Year Date and, in the event the amount of the Aggregate Unused Proceeds
exceeds $5,000,000, promptly after the Five Year Date, the Company shall
commence an Asset Sale Offer on a pro rata basis for an aggregate principal
amount of Notes equal to the Aggregate Unused Proceeds (and any other Excess
Proceeds that arise between the Five Year Date and such Asset Sale Offer) at a
purchase price equal to 100% of the principal amount of the Notes, plus accrued
interest, if any, Special Interest, if any, and Additional Amounts, if any, to
the date of purchase.

                  Within 30 calendar days of the date the amount of Excess
Proceeds exceeds $5,000,000, the Company shall send, or cause to be sent, by
first-class mail, postage prepaid, a notice regarding the Asset Sale Offer to
each Holder of Notes. The Holder of this Note may elect to have this Note or a
portion hereof in an authorized denomination purchased by completing the form
entitled "Option of Holder to Require Purchase" appearing below and tendering
this Note pursuant to the Asset Sale Offer. Unless the Company defaults in the
payment of the Offer Purchase Price with respect thereto, all Notes or portions
thereof selected for payment pursuant to the Asset Sale Offer will cease to
accrue interest and Additional Amounts, if any, and Special Interest, if any,
from and after the Asset Sale Payment Date.

         11.      Repurchase at the Option of Holders upon a Termination of
                  Trading.


                                      -10-
<PAGE>   11
                  In the event of any Termination of Trading (as defined in the
Indenture) occurring after the Issue Date and on or prior to Maturity, each
Holder of Notes will have the right commencing on the date following the Five
Year Date, at the Holder's option, to require the Company to repurchase all or
any part of such Holder's Notes on the date (the "Repurchase Date") that is 30
days after the date the Company gives notice of the Termination of Trading at a
price (the "Repurchase Price") equal to 100% of the principal amount thereof,
together with accrued and unpaid interest, if any, Additional Amounts, if any,
and Special Interest, if any, thereon to the Repurchase Date.

                  On or before the 15th day after the occurrence of a
Termination of Trading (unless such Termination of Trading occurs prior to the
Five Year Date, then on the 15th day following the Five Year Date), the Company
shall mail to all Holders of Notes a notice of the occurrence of such
Termination of Trading, the Repurchase Price and the procedures which the Holder
must follow to exercise the repurchase right. To exercise such right, the Holder
of this Note must deliver, on or before the close of business on the Repurchase
Date, irrevocable written notice to the Company (or an agent designated by the
Company for such purpose) and to the Trustee of the Holder's exercise of such
right, together with the certificates evidencing the Notes with respect to which
the right is being exercised, duly endorsed for transfer and with the form
entitled "Option of Holder to Require Purchase" appearing below completed. Such
written notice is irrevocable.


         12.      Mandatory Redemption.

                  Except as set forth in Sections 9, 10 and 11, the Company is
not required to make any mandatory redemption payments or sinking fund payments
with respect to the Notes.

         13.      The Global Note.

                  So long as this Global Note is registered in the name of the
Depositary or its nominee, members of, or participants in, the Depositary
("Agent Members") shall have no rights under the Indenture with respect to this
Global Note held on their behalf by the Depositary or the Trustee as its
custodian, and the Depositary may be treated by the Company, the Guarantors, the
Trustee and any agent of the Company, the Guarantors or the Trustee as the
absolute owner of this Global Note for all purposes. Notwithstanding the
foregoing, nothing herein shall (i) prevent the Company, the Guarantors, the
Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depositary
or (ii) impair, as between the Depositary and its Agent Members, the operation
of customary practices governing the exercise of the rights of a Holder of
Notes.

                  The Holder of this Global Note may grant proxies and otherwise
authorize any Person, including Agent Members and Persons that may hold
interests in this Global Note through Agent Members, to take any action which a
Holder of Notes is entitled to take under the Indenture or the Notes.

                  Whenever, as a result of an optional redemption of Notes by
the Company, a Change of Control Offer, an Asset Sale Offer, an offer to
purchase upon a Termination of Trading or an exchange for Certificated Notes,
this Global Note is redeemed, repurchased or exchanged in part, this Global Note
shall be surrendered by the Holder thereof to the Trustee who shall cause an
adjustment to be made to Schedule A hereof so that the principal amount of this
Global Note will be equal to the portion not redeemed, repurchased or exchanged
and shall thereafter return this Global Note to such Holder; provided that this
Global Note shall be in a principal amount of $1,000 or an integral multiple of
$1,000.

         14.      Transfer and Exchange.

                  By its acceptance of any Note represented by a certificate
bearing the Private Placement Legend, each Holder of, and beneficial owner of an
interest in, such Note acknowledges the restrictions on transfer of such Note
set forth on the face hereof, and agrees that it will transfer such a Note only
in accordance with the restrictions set forth on the face hereof and the
restrictions set forth under the heading "Transfer Restrictions" in the Final
Memorandum.

                  In connection with any transfer of a Note bearing the Private
Placement Legend, each Holder agrees to deliver to the Company such satisfactory
evidence, which may include an opinion of independent counsel licensed to
practice law in the State of New York, as reasonably may be requested by the
Company to confirm that such transfer is being made in accordance with the
limitations set forth in the Private Placement Legend. In the event the Company
determines that any such transfer is not in accordance with the Private
Placement Legend, the Company shall so inform the Registrar which shall not
register such transfer; provided that the Registrar shall not be required to
determine (but may rely on a determination made by the Company with respect to)
the sufficiency of any such evidence.

                  Upon the registration of transfer, exchange or replacement of
a Note not bearing the Private Placement Legend, the Trustee shall deliver a
Note that does not bear the Private Placement Legend. Upon the transfer,
exchange or replacement of a Note bearing the Private Placement Legend, the
Trustee shall deliver a Note bearing the Private Placement Legend, unless such
legend may be removed from such Note as provided in the next sentence. The
Private Placement Legend may be removed from a Note if there is delivered to the
Company such satisfactory evidence, which may include an opinion of independent
counsel licensed to practice law in the State of New York, as reasonably may be
requested by the Company to confirm that neither such legend nor the
restrictions on transfer set forth therein are required to ensure that transfers
of such Note will not violate the registration and prospectus delivery
requirements of the Securities Act and if the transferee is a resident of
Canada, the securities laws of the applicable province of Canada; provided that
the Trustee shall not be required to determine (but may rely on a determination
made by the Company with respect to) the sufficiency of any such evidence. Upon
provision of such evidence, the Trustee shall authenticate and deliver in
exchange for such Note, a Note or Notes (representing the same aggregate
principal amount of the Note being exchanged) without such legend. If the
Private Placement Legend has been removed from a Note, as provided above, no
other Note issued in exchange for all or any part of such Note shall bear such
legend, unless the Company has reasonable cause to believe that such other Note
represents a "restricted security" within the meaning of Rule 144 and instructs
the Trustee to cause a legend to appear thereon.

                  The Holder of this Global Note shall, by its acceptance of
this Global Note, agree that transfers of beneficial interests in this Global
Note may be effected only through a book entry system maintained by such Holder
(or its agent), and that ownership of a beneficial interest in the Notes
represented thereby shall be required to be reflected in book entry form.

                  Transfers of this Global Note shall be limited to transfers in
whole, and not in part, to the Depositary, its successors and their respective
nominees. Interests of beneficial owners in this Global Note may be transferred
in accordance with the rules and procedures of the Depositary (or its
successors).

                  This Global Note will be exchanged by the Company for one or
more Certificated Notes if (a) the Depositary (i) has notified the Company that
it is unwilling or unable to continue as, or ceases to be, a "Clearing Agency"
registered under Section 17A of the Exchange Act and (ii) a successor to the


                                      -12-
<PAGE>   13
Depositary registered as a "Clearing Agency" under Section 17A of the Exchange
Act is not appointed by the Company within 90 calendar days or (b) the
Depositary is at any time unwilling or unable to continue as Depositary and a
successor to the Depositary is not able to be appointed by the Company within 90
calendar days. If an Event of Default occurs and is continuing, the Company
shall, at the request of the Holder hereof, exchange all or part of this Global
Note for one or more Certificated Notes; provided that the principal amount of
each of such Certificated Notes and this Global Note, after such exchange, shall
be $1,000 or an integral multiple thereof. Whenever this Global Note is
exchanged as a whole for one or more Certificated Notes, it shall be surrendered
by the Holder to the Trustee for cancellation. Whenever this Global Note is
exchanged in part for one or more Certificated Notes, it shall be surrendered by
the Holder to the Trustee and the Trustee shall make the appropriate notations
thereon pursuant to Section 2.5(c) of the Indenture. All Certificated Notes
issued in exchange for this Global Note shall include the Private Placement
Legend except as set forth in Section 2.6(a)(iii) of the Indenture. Interests in
this Global Note may not be exchanged for Certificated Notes other than as
provided in this paragraph.

                  Prior to the effectiveness of a Shelf Registration Statement
or following the suspension or termination thereof, the Holder of this Note (or
holders of interests therein) and prospective purchasers designated by such
Holder (or such holders of interests therein) shall have the right to obtain
from the Company upon request by such Holder (or such holders of interests) or
prospective purchasers, during any period in which the Company is not subject to
Section 13 or 15(d) of the Exchange Act, or exempt from reporting pursuant to
12g3-2(b) under the Exchange Act, the information required by paragraph
(d)(4)(i) of Rule 144 in connection with any transfer or proposed transfer of
such Note or interest.

         15.      Denominations.

                  The Notes are issuable only in registered form without coupons
in denominations of $1,000 and integral multiples thereof of principal amount.

         16.      Unclaimed Money.

                  If money for the payment of principal or interest remains
unclaimed for two years, the Trustee or Paying Agent shall pay the money back to
the Company at its request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment unless such abandoned property
law designates another Person.

         17.      Discharge and Defeasance.

                  Subject to certain conditions, the Company at any time may
terminate some or all of its and the Guarantors' obligations under the Notes,
the Guarantees, the Indenture and the Collateral Documents if the Company
irrevocably deposits with the Trustee money or U.S. Government Obligations for
the payment of principal and interest on the Notes to redemption or maturity, as
the case may be.

         18.      Amendment, Waiver.

                  Subject to certain exceptions set forth in the Indenture, (i)
the Indenture, the Notes, the Collateral Documents and the Senior Note
Collateral Documents may be amended with the written consent of the Holders of
at least a majority in principal amount of the outstanding Notes and (ii) any
past Default and its consequences may be waived with the written consent of the
Holders of at least a majority in principal amount of the outstanding Notes.
Without the consent of any Holder of Notes, the Company, the Guarantors and the
Trustee may amend the Indenture, the Notes, the Collateral Documents and the
Senior Note Collateral Documents (i) to evidence the succession of another
Person to the Company or the Guarantors, as applicable, and the assumption by
such successor of the covenants of the Company or the Guarantors under the
Indenture, Collateral Documents and the Senior Note Collateral Documents; (ii)
to add additional covenants or to surrender rights and powers conferred on the
Company or the Guarantors by the Indenture, the Collateral Documents and the
Senior Note Collateral Documents; (iii) to add any additional Events of Default;
(iv) to provide for uncertificated Notes in addition to or in place of
Certificated Notes; (v) to evidence and provide for the acceptance of
appointment under the Indenture of a successor Trustee; (vi) to add additional
security for the Notes and the Guarantees; (vii) to cure any ambiguity in the
Indenture, the Collateral Documents or the Senior Note Collateral Documents, to
correct or supplement any provision in the Indenture, the Collateral Documents
or the Senior Note Collateral Documents which may be inconsistent with any other
provision therein or to add any other provisions with respect to matters or
questions arising under the Indenture, the Collateral Documents or the Senior
Note Collateral Documents, provided that such actions shall not adversely affect
the interests of the Holders in any material respect; (viii) to make provision
with respect to the conversion rights of the Holders of the Notes in the event
of a consolidation, merger or sale of assets involving the Company, as required
by the Indenture; or (ix) to comply with the requirements of the Commission in
order to effect or maintain the qualification of the Indenture under the Trust
Indenture Act.

         19.      Defaults and Remedies.

                  Events of Default under the Indenture include in summary form:
default in payment of interest, including Additional Amounts, if any, or Special
Interest, if any, on the Notes for 30 days; default in payment of principal on
the Notes; the occurrence and continuance of an Event of Default under the
Senior Note Indenture (as defined therein) for a period of 15 days after written
notice has been given to the Company by the Trustee or a Holder of the Notes;
failure to comply with certain of the covenants in the Indenture, including the
Change of Control covenant, the Asset Sale covenant and the Termination of
Trading covenant; failure by the Company to comply with certain of its other
agreements in the Indenture or the Notes or any Collateral Document or any
Senior Note Collateral Document or a breach of a representation or warranty in
any Collateral Document or any Senior Note Collateral Document and the
continuance of such default or breach for 45 days after notice; expropriation of
assets of the Company or any of its Restricted Subsidiaries having a book value,
less the book value of the expropriation proceeds, constituting more than 15% of
the book value, on a consolidated basis, of the Company's assets minus current
assets; defaults in the payment of certain other Indebtedness; or defaults,
other than such payment defaults, which result in the acceleration prior to
express maturity of certain other Indebtedness or which consist of the failure
to pay at maturity; certain final judgments which remain undischarged, unwaived,
if applicable, unbonded, unstayed or unsatisfied; certain events of bankruptcy
or insolvency; failure of a Guarantee, a Collateral Document or a Senior Note
Collateral Document to be in effect, the denial of obligations under a Guaranty,
a Collateral Document or a Senior Note Collateral Document or the Notes by the
Company or the Guarantors party thereto or the failure of the Notes and the
Guarantees to be secured by the theretofore perfected security interests in the
Collateral 


                                      -14-
<PAGE>   15
or the Senior Note Collateral (except as permitted by the Indenture, the
Collateral Documents or the Senior Note Collateral Documents), which in each
circumstance continues for 30 days after notice. If an Event of Default occurs
and is continuing, the Trustee or the Holders of at least 25% in principal
amount of the Notes, subject to certain limitations, may declare all the Notes
to be immediately due and payable. Certain events of bankruptcy or insolvency
are Events of Default and shall result in the Notes being immediately due and
payable upon the occurrence of such Events of Default without any further act of
the Trustee or any Holder.

                  Holders of Notes may not enforce the Indenture, the Notes, the
Guarantees, the Collateral Documents or the Senior Note Collateral Documents
except as provided in the Indenture. The Trustee may refuse to enforce the
Indenture, the Notes, the Guarantees, the Collateral Documents or the Senior
Note Collateral Documents unless it receives reasonable indemnity or security.
Subject to certain limitations, Holders of a majority in principal amount of the
Notes may direct the Trustee in its exercise of any trust or power under the
Indenture, the Collateral Documents and the Senior Note Collateral Documents.
The Holders of a majority in principal amount of the outstanding Notes, by
written notice to the Company and the Trustee, may rescind any declaration of
acceleration and its consequences if the rescission would not conflict with any
judgment or decree, and if all Events of Default have been cured or waived
except nonpayment of principal and interest that has become due solely because
of the acceleration.

         20.      Collateral Documents.

                  As provided in the Indenture, the Collateral Documents and the
Senior Note Collateral Documents, and subject to certain limitations set forth
therein, the obligations of the Company and the Guarantors under the Notes, the
Indenture and the Collateral Documents are secured by the Collateral as provided
in the Collateral Documents and the Senior Note Collateral as provided in the
Senior Note Collateral Documents. Each Holder, by accepting a Note, agrees to be
bound to all the terms and provisions of the Collateral Documents and the Senior
Note Collateral Documents, as the same may be amended from time to time. The
Liens created under the Collateral Documents and the Senior Note Collateral
Documents shall be released upon the terms and subject to the conditions set
forth in the Indenture, the Collateral Documents and the Senior Note Collateral
Documents.

         21.      Individual Rights of Trustee.

                  Subject to certain limitations imposed by the Trust Indenture
Act, the Trustee or any Paying Agent or Registrar, in its individual or any
other capacity, may become the owner or pledgee of Notes and may otherwise deal
with the Company, the Guarantors, its Restricted Subsidiaries or its Affiliates
with the same rights it would have if it were not Trustee, Paying Agent or
Registrar, as the case may be, under the Indenture.

         22.      No Recourse Against Certain Others.

                  No director, officer, employee, incorporator or stockholder of
the Company or the Guarantors, as such, shall have any liability for any
obligations of the Company or the Guarantors under the Notes, the Guarantees or
the Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation, solely by reason of his or her status as a
director, officer, employee, incorporator or stockholder of the Company or any
Guarantor. By accepting a Note, each Holder waives 


                                      -15-
<PAGE>   16
and releases all such liability (but only such liability) as part of the
consideration for issuance of such Note to such Holder.

         23.      Governing Law.

                  THE INDENTURE, THE GUARANTEES AND THIS NOTE SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE
TO AGREEMENTS MADE AND TO BE PERFORMED IN SAID STATE.

         24.      Abbreviations.

                  Customary abbreviations may be used in the name of a Holder or
an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the
entireties), JT TEN (= joint tenants with right of survivorship and not as
tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors
Act).

         25.      CUSIP Numbers.

                  Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures, the Company has caused CUSIP numbers
to be printed on the Notes and have directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Holders. No representation is made as
to the accuracy of such numbers either as printed on the Notes or as contained
in any notice of redemption and reliance may be placed only on the other
identification numbers placed thereon.

         26.      Subordination.

                  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.


         27.      Conversion Rights.

                  Subject to and upon compliance with the provisions of the
Indenture, the Holder of this Note is entitled, at his, her or its option, at
any time on or after 9:00 a.m. New York City time on July 30, 1996 and before
the close of business on the Business Day next preceding the Redemption Date, 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 next preceding the Redemption Date, to convert this
Note at the principal amount hereof, or of such portion, in to fully paid and
non-assessable shares (calculated as to each conversion to the nearest 1/100th
of a share) of Common Stock of the Company at a conversion price equal to $6.90
per share of such Common Stock (or in each case at the current adjusted
conversion price if an adjustment has been made as provided in the Indenture) by


                                      -16-
<PAGE>   17
surrender of this Note, duly endorsed or assigned to the Company or in blank, to
the Company at its office or agency maintained for that purpose pursuant to the
Indenture, accompanied by written notice to the Company in the form provided in
this Note (or such other notice as is acceptable to the Company) that the Holder
hereof elects to convert this Note and, in case such surrender shall be made
during the period from the close of business on any regular Record Date next
preceding any Interest Payment Date or the close of business on a record date
for the payment of a Reset Penalty to the close of business on such Interest
Payment Date or the Reset Penalty Payment Date, as applicable, (unless this Note
or the portion thereof being converted has been called for redemption on a
Redemption Date within such period), also accompanied by payment 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 of this Security then being converted and/or any Reset Penalty due.
Subject to the aforesaid requirement for payment and, in the case of a
conversion after the regular Record Date next preceding any Interest Payment
Date and on or before such Interest Payment Date, to the right of the Holder of
this Note (or any Predecessor Security) of record at such regular record date to
receive an installment of interest (with certain exceptions provided in the
Indenture), no payment or adjustment is to be made upon conversion on account of
any interest accrued hereon or on account of any dividends on the Common Stock
issued upon conversion. No fractional shares or scrip representing fractions of
shares will be issued on conversion, but instead of any fractional share the
Company shall pay a cash adjustment as provided in the Indenture.

         On December 1, 1996 (the "Reset Date"), the conversion price will be
adjusted (the "Conversion Reset") to equal (x) the product of (i) the average of
the high and low prices on the Nasdaq National Market, or the consolidated
transaction reporting tape in the event that the Common Stock of the Company is
not then traded on the Nasdaq National Market, and (ii) the amount of Common
Stock of the Company reported as being traded on that day, for each Trading Day
of the 30 calendar days preceding the Reset Date (the "Conversion Reset
Period"), divided by the total number of shares of Common Stock of the Company
traded over the Conversion Reset Period, then multiplied by (y) 115% (the
"Conversion Reset Price"), if such Conversion Reset Price shall be lower than
the conversion price before such calculation, provided that the Conversion Reset
Price shall never be adjusted to less than $4.30 per share, but the Company will
be required to pay to holders of Notes a quarterly reset penalty ("Reset
Penalty") attributable to the Company's inability to adjust the Conversion Reset
Price below $4.30 per share. In the event that the conversion price before such
calculation shall be equal to or less than the Conversion Reset Price, then no
adjustment to the conversion price shall be made. The quarterly Reset Penalty
payable to each Holder of Notes shall be an amount equal to $2.50 per Note held
by such Holder (which for the purposes of this Paragraph 27 will be determined
to be Certificated Notes, each in the denomination of $1,000) unless, but for
the proviso in the preceding sentence, the Conversion Reset Price would have
been less than $3.80 per share, in which case such quarterly Reset Penalty shall
be an amount equal to $5.00 per Note held by such Holder. The Reset Penalty
shall be payable on each March 1, June 1, September 1 and December 1 (each such
date being referred to herein as a "Reset Penalty Payment Date"), commencing on
March 1, 1997, the first such Reset Penalty Payment Date occurring after the
Reset Date, and shall be payable to holders of record of Notes on the February
15, May 15, August 15 and November 15 immediately preceding such Reset Penalty
Payment Date and shall not accrue. The Reset Penalty will cease to be payable
upon an conversion of a Note.
