ARTICLE 3 CONVERSION PRIVILEGE Page 96 3.1 Conversion into Common Shares ----------------------------- The holder of Series A Preferred Shares shall have the right, at such holder's option, at any time, to convert any or all of such shares into fully paid and non-assessable Common Shares at a Conversion Price of $2.60 per Common Share, such Conversion Price being subject to adjustment from time time as provided in Section 3.4. The number of Common Shares issuable upon conversion of any Series A Preferred Shares shall, subject to the exception as to fractions contained in Section 3.2, be computed by multiplying the number of Series A Preferred Shares to be converted by $2.60 and dividing the product by the Conversion Price. 3.2 Conversion Procedure -------------------- (1) The right to convert any Series A Preferred Shares into Common Shares may be exercised by surrendering, at any office of the Transfer Agent at which the Series A Preferred Shares are transferable, the certificate representing such shares and a notice in writing (which notice shall be and be deemed to be irrevocable) specifying the election to convert such Series A Preferred Shares, the number of Series A Preferred Shares desired to be converted and the name or names in which the Common Shares resulting from such conversion are to-be registered.

(3) Upon the conversion of any Series A Preferred Shares, there shall be no payment or adjustment by the Corporation or by the holder of such Series A Preferred Shares on account of any dividend either on the shares so converted or on the Common Shares resulting from such conversion. (4) The share certificates representing the Common Shares resulting from any conversion of Series A Preferred Shares shall be issued as promptly as practicable in the name of the holder of the Series A Preferred Shares so converted, or subject to payment by such holder of any stock transfer or other applicable taxes, in such name or names as such holder may direct Page 97 in writing (either in the notice referred to in Section 3.2(l) or otherwise). (5) The Conversion Privilege shall be deemed to have been exercised, and the holder of the Series A Preferred Shares so converted (or any person or persons in whose name or names such holder shall have directed certificates representing Common Shares to be issued) shall be deemed to become a holder of Common Shares of record for all purposes, on the date of surrender of the certificates representing the Series A Preferred Shares so converted accompanied by the notice referred to in Section 3.2(l), notwithstanding any delay in the delivery of the certificates representing the Common Shares into which such Series A Preferred Shares have been converted, provided, however, that in the event the share transfer registers for Common Shares shall be closed on such date, the surrender of the Series A Preferred Shares and the conversion thereof to Common Shares shall be effective on the next succeeding day on which such share transfer registers are open. 3.3 Avoidance of Fractional Shares ------------------------------ In any case where a fraction of a Common Share would otherwise be issuable upon conversion of one or more Series A Preferred Shares: (a) the Conversion Privilege shall be deemed to have been exercised only with respect to that number of Series A Preferred Shares as can be converted into a whole number of Common Shares; and (b) the Corporation shall adjust such fractional interest in a Common Share by the payment by cheque of an amount equal to the product of such fractional interest and the Conversion Price applicable to the conversion of such Series A Preferred Shares. 3.4 Adjustment of Conversion Privilege ---------------------------------- (1) Definitions ----------- In this Section 3.4: (a) "Additional Common Shares" mean all Common Shares issued by the ------------------------ Corporation after the Original Issue Date and all Common Shares issuable by the Corporation on the conversion of Convertible Securities after the Original issue Date, other than Common Shares issued or issuable: (i) upon conversion of any Series A Preferred Shares; Page 98 (ii) to officers, directors or employees of, or consultants to, the Corporation pursuant to a stock option or option plan or other employee stock incentive programs contemplated by the Corporation on the Original Issue Date; (iii) as consideration for the-purchase of intellectual property rights and technology pursuant to an agreement dated June 9, 1986 between Mr. Terence H. Matthews, Newbridge Communication Networks Corp. and the Corporation; and (iv) by way of stock dividend declared pursuant to Section 2.1; (b) "Convertible Securities" mean any evidences of indebtedness, shares or --------------------- other securities directly or indirectly convertible into or exchangeable for Common Shares; (c) "current market value" of the Common Shares at any date means a price -------------------- per share equal to the last board lot sale price on The Toronto Stock Exchange, on the trading day next preceding such date, or, if the Common Shares are not then listed on The Toronto Stock Exchange, on such other stock exchange on which such shares are listed as may be selected for such purpose by the Directors, or, the Common Shares are not listed on any stock exchange, the current market value as determined in good faith by the Directors; (d) "Original Issue date" means October 14, 1987; and (e) "Option" shall mean any right, option or warrant to subscribe for, ------ purchase or otherwise acquire either Common Shares or Convertible Securities. (2) Share Reorganization -------------------- If and whenever the Corporation shall: (i) subdivide the outstanding Common Shares into a greater number of shares; or (ii) consolidate the outstanding Common Shares into a smaller number of shares; (any of such event being herein called "Sharp Reorganization"), the conversion -------------------- Price shall be adjusted, effective immediately after the record date at which the holders of Common Shares are determined for the purposes of the Share Reorganization, or, if no record date is fixed the effective date of the Share Reorganization, by multiplying the Page 99 Conversion Price in effect on such record or effective date by a fraction of which: (A) the numerator shall be the number of Common Shares outstanding on such record or effective date; and (B) the denominator shall be the number of Common Shares outstanding after giving effect to such Share Reorganization, including, in the case of securities exchangeable for or convertible into Common Shares, the number of Common Shares that would have been outstanding if such securities had been exchanged for or converted into Common Shares on such record or effective date. (3) Capital Reorganization ---------------------- If and whenever there shall occur a reclassification or redesignation of the Common Shares or any change of the Common Shares into other shares, otherwise than in a Share Reorganization (any such event being herein called "Capital ------- Reorganization"), the holder of any Series A Preferred Shares who exercises the - -------------- Conversion Privilege after the effective date of Capital Reorganization shall be entitled to receive and shall accept, upon the exercise of such right, in lieu of the number of Common Shares to which such holder was theretofore entitled upon exercise of the Conversion Privilege , the aggregate number of shares Or other securities or property of the Corporation or of the body corporate resulting from such Capital Reorganization that such holder would have been entitled to receive as a result of such Capital Reorganization if, on the effective date thereof, such holder had been the holder of the number of Common Shares to which such holder was theretofore entitled upon conversion; provided, -------- however, that no Capital Reorganization shall bet carried into effect unless all necessary steps shall have been taken so that the holders of Series A Preferred Shares shall thereafter be entitled to receive such number of shares or other securities of the Corporation or of the body corporate resulting from such Capital Reorganization, subject to adjustment thereafter in accordance with the provisions of the same, as nearly as may be possible, as those contained in this Section 3.4 and Section 3.5. (4) Conversion Price Adjustment --------------------------- If and whenever the Corporation shall issue Additional Common Shares without consideration or for a consideration per share less than $2.60 or the market price of the Series A Preferred Shares, whichever is greater and if such issuance does not constitute a Share Reorganization or Special Distribution (any such event being herein called an "Additional Distribution"), the Conversion ----------------------- Price shall be adjusted concurrently with such issue or deemed issue by multiplying the Conversion Price by a fraction of which: (A) the numerator shall be the number of Common Shares outstanding Page 100 immediately prior to such issue excluding any Common Shares which were issued as a result of any exclusion enumerated in Section 3.4(l)(a) but including the number of Common Shares which could be purchased based on the aggregate consideration received by the Corporation for the total number of Additional Common Shares so issued at the then Conversion Price, and (B) the denominator shall be the number of Common Shares outstanding immediately prior to such issue excluding any Common Shares which were issued as a result of any exclusion enumerated in Section 3.4(l)(a) but including the number of such Additional Common Shares so issued. For purposes of this Section 3.4(4), the consideration received by the Corporation for the issue of any Additional Common Shares shall be computed as follows: (X) insofar as it consists of cash, be computed at the aggregate amount of cash received by the Corporation excluding amounts paid or payable for accrued interest or accrued dividends; (Y) insofar as it consists of property other than cash, be computed at the fair market value thereof at the time of such issue, as determined in good faith by the directors; and (Z) in the event Additional Common Shares are issued together with other shares or securities or other assets of the Corporation for consideration which covers both, be the proportion of such consideration so received for the Additional Common Shares, computed as provided in clauses (M) and (Y) above, as determined in good faith by the Directors. (5) Special Distribution -------------------- If and whenever the Corporation shall issue or distribute to holders of Common Shares: (a) shares of the Corporation of any class other than Common Shares; (b) Options or Convertible Securities; (c) evidences of indebtedness; or (d) any other assets (excluding cash dividends); for less than fair consideration (as determined by the Board of Directors) and if such issuance or distribution does not constitute a Share Reorganization (any such event being herein called "Special Distribution "), the Conversion Price -------------------- shall be adjusted, Page 101 effective immediately after the record date at which the holders of Common Shares are determined for purposes of the Special Distribution, by multiplying the Conversion Price in effect on such record date by a fraction of which: (i) the numerator shall be the difference between: (A) the product of the number of Common Shares outstanding on such record date and - the current market value of the Common Shares on such date; and (B) the fair market value to the holders of Common Shares, as determined by the Directors (whose determination shall be conclusive) of the shares, rights, options, warrants, evidences of indebtedness or other assets issued or distributed in the Special Distribution, and (ii) the denominator shall be the product of the number of Common Shares outstanding on such record date and the current market value of the Common Shares on such date. 3.5 Adjustment Rules ---------------- The following rules and procedures shall be applicable to adjustments of the Conversion Privilege made pursuant to Section 3.4: (a) no adjustment in the Conversion Price shall be required unless such adjustment would result in a change of at least $0.01 in the Conversion Price then in effect, provided, however, that any adjustments which, but for the provisions of this Section 3.5(a) would otherwise have been required to be made, shall be carried forward and taken into account in any subsequent adjustments; (b) no adjustment in the Conversion Price shall be made in respect of any event described in Section 3.4 (other than an event described in Section 3.4 (2) (i) or (ii) and in Section 3. 4 (3) ) if the holders of the Series A Preferred Shares are entitled to participate in such event on the same terms mutatis mutandis as if they had converted ---------------- their Series A Preferred Shares prior to the effective date of such event; (c) no adjustment in the Conversion Price shall be made pursuant to Section 3.4 in respect of the issue from time to time of Common Shares to holders of Common Shares who exercise an option to receive substantially equivalent dividends in Common Shares in lieu of receiving cash dividends or pursuant to any dividend reinvestment plan of the Page 102 Corporation; (d) if a dispute shall at any time arise with respect to any adjustment of the Conversion Privilege, such dispute shall be conclusively determined by the auditor of the Corporation or, if they are unable or unwilling to act, by a firm of independent chartered accountants selected by the Directors and in any such determination, shall be binding upon the Corporation and all transfer agents and shareholder's of the Corporation; and (e) forthwith after any adjustment of the Conversion Privilege pursuant to Section 3.4, the Corporation: (i) file with the Transfer Agent a certificate certifying as to the particulars of such adjustment and, in reasonable detail, the event requiring and the manner of determining such adjustment; and (ii) give written notice to the holders of Series A Preferred Shares of the Conversion Privilege following such adjustment. 3.6 Mandatory Conversion -------------------- After receiving a receipt for a final prospectus for and prior to the closing of an underwritten public offering of the Common Shares of the Corporation, the Corporation may at its option, by notice in writing to each of the holders, require the holders to convert all of the issued and outstanding Series A Preferred Shares held by such holders into Common Shares at the Conversion Price. A notice of conversion shall be given by the Corporation not less than 10 days prior to and shall be subject to the closing of the underwritten public offering of the Common Shares of the Corporation and shall specify therein the date fixed for closing such offering and the date upon which the Series A Preferred Shares will be deemed to be converted into Common Shares at the Conversion Price. 3.7 Cancellation ------------ All Series A Preferred Shares surrendered upon the exercise of the conversion right shall be cancelled by the Transfer Agent and the number thereof shall not be restored to the status of authorized but unissued shares. 3.8 Reservation of Common Shares ---------------------------- So long as any of the Series A Preferred Shares are outstanding and entitled to the Conversion Privilege and at any time that the authorized number of Common Shares is not unlimited, the Corporation shall reserve and at all times hold out of its Page 103 unissued Common Shares, against the Conversion Privilege herein conferred upon the holders of the Series A Preferred Shares, a sufficient number of unissued Common Shares to be converted upon the basis and upon the terms and conditions provided in this Article 3. 3.9 Compliance with Laws -------------------- If any Common Shares reserved or to be reserved for the purpose of conversion of the Series A Preferred Shares hereunder, require registration with or approval of any governmental authority under any Canadian or Provincial law before such shares may be validly issued upon conversion, the Corporation will take such action as may be necessary to secure such registration or approval, as the case may be. ARTICLE 4 VOTING RIGHTS 4.1 Voting Rights ------------- Each holder shall be entitled to receive notice of and to attend any annual or special meeting of the shareholders of the Corporation and shall be entitled to one vote for each Series A Preferred Share held by such holder. ARTICLE 5 LIQUIDATION 5.1 Liquidation ----------- In the event of the liquidation, dissolution or winding-up of the Corporation, whether voluntary or involuntary, or any other distribution of assets of the Corporation among its shareholders for the purpose of winding up its affairs, the holders of the Series A Preferred Shares shall be entitled to receive, before any distribution of any part of the assets of the Corporation among the holders of any other shares, an amount equal to $2.60 plus an amount equal to any dividends declared thereon and unpaid and no more. For the purposes of this Section 5.1, liquidation includes a disposition of substantially all of the assets of the Corporation whether by sale, merger or other reorganization. Upon payment of the amounts so payable to them, the holders of the Series A Preferred Shares shall not be entitled to share in any further distribution of assets of the Corporation. ARTICLE 6 PURCHASE 6.1 Purchase -------- Page 104 Subject to the provisions of applicable law, the Corporation may purchase at any time all or from time to time any number of the outstanding Series A Preferred Shares in the open market or pursuant to tenders received by the Corporation upon invitation for tenders addressed to all holders at the lowest price or prices which in the opinion of the Directors such shares are obtainable but not exceeding $2.60 per Series A Preferred Share. If upon any invitation for tenders, the Corporation receives tenders for Series A Preferred Shares at the same price in an aggregate number greater than the number for which the Corporation is prepared to accept tenders, the shares to be purchased shall be selected from the shares offered at such price as nearly as may be pro rata, disregarding fractions, according to the number of Series A Preferred Shares offered in each such tender, in such manner as the Directors in their sole discretion shall determine. ARTICLE 7 FURTHER SERIES OF PREFERRED SHARES 7.1 Further Series of Preferred Shares ---------------------------------- So long as the Series A Preferred Shares are outstanding, the Corporation shall not, without the approval of the holders of the Series A Preferred Shares, issue any further series of Preferred Shares.

On every poll taken at every such meeting or adjourned meeting every holder shall be entitled to one vote in respect of each Series A Preferred Share held by him. 8.3 Notices ------- Any notice required or permitted to be given to a holder shall be mailed by letter, postage prepaid, or delivered to such holder at his address as it appears on the records of the Corporation or in the event of the address of any such holder not so appearing then to the last known address of such holder.
