This Debenture is one of the 7.00% Equity Subordinated Debentures due December 31, 2006 in the aggregate original principal amount of $150,000,000 in lawful money of Canada which amount was thereafter reduced on February 5, 2002, issued under an Indenture dated as of February 15, 1999 and made between the Company and Montreal Trust Company of Canada, as Trustee, as amended by Supplemental Indenture dated as of February 5, 2002 and made between the Company, Montreal Trust Company of Canada and Computershare Trust Company of Canada (the Indenture and the Supplemental Indenture collectively referred to as (the Indenture).  Reference is hereby made to the Indenture for a description of the rights of the holders of the said Debentures, of the Company and of the Trustee and of the terms and conditions upon which the Debentures are issued and held, all to the same effect as if the provisions of the Indenture were herein set forth, to all of which provisions the holder of this Debenture, by acceptance hereof, assents. All terms not otherwise defined herein shall have the meanings ascribed thereto in the Indenture.

The Debentures are issuable as fully registered Debentures in denominations of $250 and integral multiples of $250 and in other authorized denominations. The Debentures of any authorized denomination may be exchanged, as provided in the Indenture, for Debentures in same aggregate principal amount in any other authorized denomination.

This Debenture and all other Debentures certified and issued under the Indenture rank pari passu in accordance to their tenor without discrimination, preference or priority. The payment of the principal and interest on the Debentures is subordinated to the prior payment in full of Senior Liabilities (as defined in the Indenture). The Indenture does not restrict the Company from incurring additional Indebtedness for borrowed money or from mortgaging, pledging or charging its properties to secure any Indebtedness.

Each Debenture is convertible at maturity, at the option of the holder into that number of Subordinate Voting Shares equal to the Conversion Number. The Conversion Number will be calculated as of the date of conversion as (i) the Conversion Value as of such date (being the Subordinate Voting Share Value) divided by (ii) 95% of the then Current Market Price of the Subordinate Voting Shares. The Subordinate Voting Share Value will be equal to 56.818182 multiplied by the Current Market Price of the Subordinate Voting Shares on the date of conversion. The Company has the option, upon at least 40 days and not more than 60 days prior notice, in lieu of delivering Subordinate Voting Shares on conversion, to pay the Conversion Value in cash for Debentures tendered for conversion. The Conversion Number is subject to adjustment upon the occurrence of certain events. The Debentures will be convertible at the option of the holder prior to the Maturity Date upon the occurrence of an Offer or an Event of Default. Upon a conversion of Debentures, the Company will pay interest accrued to the date of conversion in cash (except in the case of a conversion upon an Event of Default).

---





The Company will send to Debentureholders at least 40 days and not more than 60 days prior to the Maturity Date a maturity notice (the Maturity Notice) which will provide Debentureholders with the following options:

(a)

to convert Debentures only if the Subordinate Voting Share Value at the Maturity Date is greater than or equal to $250;

(b)

to convert Debentures whether or not the Subordinate Voting Share Value at maturity exceeds $250; or

(c)

to receive payment of the principal amount of the Debentures in cash, subject to exercise of the Share Repayment Right (as hereinafter defined);

it being understood, in each case, that the accrued interest, if any, shall be paid in cash.

Debentureholders who select option (a), (b) or (c) above will be required to deliver to the Trustee before the close of business on the third trading day prior to Maturity Date (the Determination Date) a duly completed exercise notice in prescribed form, together with the related Debentures. Debentureholders who do not deliver a duly completed exercise notice on or before the close of business on the Determination Date will be deemed to have selected option (a) and the Debentures held by such holders will automatically be converted if the Subordinate Voting Share Value at the Maturity Date is greater than or equal to $250. The Company shall specify in the Maturity Notice whether it will deliver Subordinate Voting Shares on conversion of the Debentures or elects to pay the Conversion Value in cash and whether, if a holder selects option (c), the Company will exercise its Share Repayment Right.

Provided that no Event of Default shall have occurred and be continuing, the Company may, at its option, elect to satisfy its obligation to repay on the Maturity Date the principal amount of all, but not less than all, of the Debentures outstanding and the interest accrued on such Debentures by delivering to holders that number of Freely Tradeable (as defined in the Indenture) Subordinate Voting Shares equal to the number obtained by dividing the principal amount of the Debentures by the greater of the Maturity Conversion Price and 95% of the then Current Market Price of the Subordinate Voting Shares on the Maturity Date (the Share Repayment Right). The Maturity Conversion Price is initially set at $1.00 and is subject adjustments upon the occurrence of certain events.

The Company will promptly deliver a notice in a form similar to the Maturity Notice to Debentureholders if and when an Offer or an Event of Default is made setting out the manner in which the conversion right may be exercised and specifying whether the Company elects, in lieu of delivering Subordinate Voting Shares, to pay the Conversion Value in cash for Debentures tendered for conversion.

Provided no Event of default has occurred and is continuing, the Company shall also have the right to purchase for cancellation the Debentures in the open market or by tender or by private contract at any price, subject to compliance with Applicable Securities Legislation. Debentures purchased by the Company shall be cancelled and shall not be reissued.

---



The principal hereof may become or be declared due before the stated maturity on the conditions, in the manner, with the effect and at the time set forth in the Indenture.

The Indenture contains provisions for the holding of meetings of Debentureholders and rendering resolutions passed at such meetings and instruments in writing signed by the holders of 66 2/3% of the Debentures outstanding binding upon all Debentureholders subject to the provisions of the Indenture.

This Debenture may only be transferred upon compliance with the conditions precedent in the Indenture on one of the registers to be kept at the offices of the Trustee in the Cities of Vancouver, Calgary, Toronto, Winnipeg and Montreal and at such other place or places, if any, and/or by such other registrar or registrars, if any, as the Company with the approval of the Trustee may designate, and may be exchanged at any such place, by the registered holder hereof or his executors or administrators or other legal representatives or his or their attorney duly appointed by an instrument in writing in form and execution satisfactory to the Trustee, and upon compliance with such reasonable requirements as the Trustee and/or other registrar may prescribe, and such transfer shall be duly noted thereon by the Trustee or other registrar.

This Debenture shall not become obligatory for any purpose until it shall have been certified by the Trustee for the time being under the Indenture.

The Holder of this Debenture, by receiving and holding same, hereby accepts and agrees to be bound by the terms, and to be entitled to the benefits of this Debenture and of the Indenture and confirms the appointment of the Trustee as fondé de pouvoir (holder of the power of attorney) of the Holder of the Debenture to the extent necessary for the purposes hereof and of the Indenture, the whole in accordance with and subject to the respective provisions thereof.

DUE 2006

MATURITY NOTICE

To:

Holders of 7.00% Equity Subordinated Debentures Due December 31, 2006 (the Debenture) of Telesystem International Wireless Inc. (the Company)

Notice is hereby given pursuant to Section 4.01 of the Indenture dated as of February 15, 1999 between the Company and Montreal Trust Company of Canada, as trustee (the Trustee) as amended, that the Debentures will become due and payable as of December 31, 2006 (the Maturity Date) and that each $250 in principal amount of Debentures will become convertible, at the option of the holder thereof, into the Conversion Number of Subordinate Voting Shares in effect as of the Maturity Date.  The Conversion Number of Subordinate Voting Shares as of the Maturity Date will be calculated as (a) the Subordinate Voting Shares Value divided by (b) 95% of the Weighted Average Trading Price of Subordinate Voting Shares on The Toronto Stock Exchange for the 20 consecutive Trading Days ending on or immediately prior to  [the fourth Trading Day prior to the Maturity Date] (the Current Market Price).  The Subordinate Voting Shares Value will be equal to the product of [250] (the Subordinate Voting Share Rate) and the Current Market Price. The Subordinate Voting Share Rate is subject to adjustment for the occurrence of certain events to the Maturity Date as set forth in the Indenture.  The Company will provide holders of the Debentures with notice of any such adjustment as soon as practicable after the occurrence thereof.

[Pursuant to Section 4.01(4) of the Indenture, the Company hereby irrevocably elects to pay, to holders of Debentures who have elected or are deemed to have elected to convert their Debentures in Subordinate Voting Shares, [the Conversion Number of Subordinate Voting Shares as of the Maturity Date] [an amount in cash equal to the Conversion Value of such Debentures in lieu of the conversion of such Debentures into Subordinate Voting Shares] [and irrevocably elects to deliver to holders of Debentures who have not elected or are deemed not to have elected to convert their Debentures into Subordinate Voting Shares (and cash in lieu of fractional Subordinate Voting Shares) that number of Freely Tradable Subordinate Voting Shares equal to the principal amount of such Debentures divided by the greater of the Maturity Conversion Price and 95% of the Current Market Price of Subordinate Voting Shares on the Maturity Date.]

Each holder of Debentures has the following options in respect of the maturity of the Debentures:

(a)

to convert Debentures only if the Subordinate Voting Shares Value as of the Maturity Date is greater than or equal to $250;

(b)

to convert Debentures whether or not the Subordinate Voting Shares Value as of the Maturity Date exceeds $250; or

(c)

to receive payment of the principal amount of the Debentures [in cash] [in Subordinate Voting Shares];

it being understood, in each case, that the accrued interest, if any, shall be paid in cash.

Holders who select option (b) may be acting contrary to their economic interests since, if the Subordinate Voting Shares Value as of the Maturity Date is less than $250, holders may receive greater consideration under option (c).

A holder who selects option (a), (b) or (c) will be required to deliver to [the Trustee/alternate conversion agent] at any of the following corporate trust offices:

[set out addresses of corporate trust offices in Toronto, Montreal, Calgary, Vancouver and Winnipeg]

before the close of business on December  , 2006 [third Trading Day prior to the Maturity Date] (the Determination Date) an exercise notice in the form annexed hereto duly completed and executed by such holder or his executors or administrators or other legal representatives or his or their attorney duly appointed by instrument in form and execution satisfactory to the Trustee, together with the Debentures to which such notice relates.  Holders who do not deliver duly completed exercise notices on or before the close of business on the Determination Date will be deemed to have selected option (a).  Debentures held by holders who are so deemed to have selected option (a) will automatically be converted if the Subordinate Voting Share Value as of the Maturity Date is greater than or equal to $250.

A holders selection of an option on the Determination Date should take into account the Current Market Price of Subordinate Voting Shares as of the Maturity Date which is defined as the 20 day Weighted Average Trading Price determined as of the fourth Trading Day ending on or immediately prior to the Maturity Date.  This amount may be more or less than the market price of a Subordinate Voting Shares on the Maturity Date.

NOTICE OF AN OFFER

To:

Holders of 7.00% Equity Subordinated Debentures Due December 31, 2006 (the Debentures) of Telesystem International Wireless Inc. (the Company)

Notice is hereby given pursuant to Section 4.02 of the Indenture dated as of February 15, 1999 between the Company and Montreal Trust Company of Canada, as trustee (the Trustee) as amended, that as a result of an Offer (as defined in the Indenture) having been made on  in respect to Subordinate Voting Shares each $250 in principal amount of Debentures will become convertible, at the option of the holder thereof, on  [Early Conversion Date] (the Early Conversion Date), for the sole purpose of allowing the holder to accept the Offer into the Conversion Number of Freely Tradeable Subordinate Voting Shares in effect on the Early Conversion Date, subject to the terms and conditions herein and in the Indenture.  The Conversion Number of Subordinate Voting Shares on the Early Conversion Date will be calculated as (a) the amount equal to the Conversion Value divided by (b) the Current Market Price.  The Current Market Price shall be equal to the aggregate of (a) the amount of cash received in respect of each Subordinate Voting Shares pursuant to the Offer and (b) an amount equal to the Fair Market Value as at the Early Conversion Date of securities or any other property received in respect of each Subordinate Voting Shares pursuant to the Offer, as certified by an Officers Certificate.

If the Offer is made for less than all of the outstanding Subordinate Voting Shares not held by the offeror and less than all of the Subordinate Voting Shares deposited pursuant to the Offer are taken up by the offeror, then each holder who tenders Debentures for conversion shall be deemed to have elected to convert, for the sole purposes of allowing the Holder to accept the Offer only that portion of his Debentures so tendered equal to the percentage which the Subordinate Voting Shares taken up by the offeror represents of all Subordinate Voting Shares deposited pursuant to the Offer (other than Subordinate Voting Shares converted).
