Holder: Myer Bentob

Date: August 7, 2003

                                     WARRANT

To subscribe for and purchase shares of Common Stock, par value US$0.001, of

                           UNITY WIRELESS CORPORATION

Reference is made to a Subscription Agreement (the "Agreement") dated August 7,
2003 between Holder and the Company. Capitalized terms used herein have the
meanings attributed thereto in the Agreement unless otherwise set forth herein.

THIS CERTIFIES that, for value received, Holder or its registered successors and
assigns, is entitled to purchase from UNITY WIRELESS CORPORATION, a Delaware
corporation (herein called the "Company"), 416,667 shares of Common Stock of the
Company (individually a "Common Share", and collectively the "Common Shares") at
the initial exercise price of CDN$0.36 (US$0.26) per Common Share (the "Exercise
Price") at any time until 5:00 p.m. (Montreal time) on August 7, 2005. The
number of Common Shares to be received upon the exercise of the Warrant and the
Exercise Price are subject to adjustment from time to time as hereinafter set
forth.

<PAGE>

1.    Exercise of Warrant.

(a)   This Warrant may be from time to time exercised by the Holder, in whole or
      in part, by the surrender of this Warrant, duly endorsed, accompanied by a
      duly completed Form of Exercise, in the form attached hereto, and payment
      in full of the Exercise Price for the Common Shares acquired at the
      principal office of the Company. Payment of the Exercise Price shall be
      made in cash or by certified or official bank check or checks payable to
      the order of the Company. The certificate(s) for such Common Shares shall
      be delivered to the Holder within a reasonable time, not exceeding five
      days, after the Warrant evidenced hereby shall have been so exercised and
      a new Warrant evidencing the number of Common Shares remaining to be
      issued upon exercise of the Warrant shall also be issued to the Holder
      within such time unless such Warrant shall have expired.

2.    Anti-Dilution Provisions.

(b)   General. The Exercise Price per Common Share shall be subject to
      adjustment from time to time as hereinafter provided. Upon each adjustment
      of the Exercise Price, the Holder shall thereafter be entitled to
      purchase, at the Exercise Price resulting from such adjustment, the number
      of Common Shares obtained by multiplying the number of Common Shares
      immediately theretofore subject to this Warrant by the Exercise Price in
      effect immediately prior to such adjustment, and dividing such amount by
      the Exercise Price resulting from such adjustment.

(c)   Stock Splits and Reverse Splits. In the event the Company subdivides its
      outstanding Common Shares into a greater number of shares, the Exercise
      Price in effect immediately prior to the subdivision shall be
      proportionately reduced, and conversely, in the event that the outstanding
      Common Shares of the Company are combined into a smaller number of shares,
      the Exercise Price in effect immediately prior to the combination shall be
      proportionately increased.

(d)   Reorganizations and Asset Sales. Upon any consolidation or merger of the
      Company with another corporation, or the sale of all or substantially all
      of its assets to another corporation (other than a consolidation or merger
      in which the Company is the continuing corporation) (each, a
      "Combination"), the Company shall enter into an agreement with the
      surviving or acquiring Person (the "Successor Company") in such
      Combination confirming the Holder's rights pursuant to this Warrant and
      providing for the continuation after such Combination of the adjustments
      provided for in this Warrant, to the end that the Warrant shall
      effectively be converted into a Warrant of the Successor Company on the
      terms set forth herein. Following a Combination, the Warrant shall be
      exercisable for such number of shares of stock or other securities or
      property (including cash) to which the Common Shares issuable upon the
      exercise of the Warrant (at the time of such Combination) would have been
      exchanged pursuant to such Combination had such Common Shares been
      outstanding. For example, if the Company is acquired in a transaction in
      which each of its Common Shares is converted into the right to receive two
      shares of the common stock of the Successor Company and this Warrant,
      after giving effect to any other adjustments hereunder (including, without
      limitation, adjustments under any of the other provisions of this Section
      2, whether in respect of such Combination or otherwise), is then
      exercisable for 1,000 shares of common stock of the Successor Company, the
      Company would enter into an agreement with the Successor Company providing
      that the Warrant would be exercisable for 2,000 shares of the Successor
      Company's common stock, which agreement would include the adjustment
      provisions provided in this Agreement, effectively converting the Warrant
      into warrants of the Successor Company. The provisions of this Section
      shall similarly apply to successive Combinations involving any Successor
      Company.

3.    Dividends and Distributions. If, after the date hereof and prior to the
      exercise of this Warrant, the Company shall pay any dividends or make any
      other distributions to the holders of its Common Shares, upon the exercise
      of this Warrant the Company shall pay to the Holder the amount of such
      dividend or distribution which the Company would have paid to the Holder
      had it exercised this Warrant in full immediately prior to the record date
      for such dividend or distribution.

4.    Notices. If at any time prior to the expiration of the Warrants:

(a)   The Company shall declare any dividend or distribution on the Common
      Shares payable in shares of capital stock of the Company, cash or other
      property;

(b)   The Company shall authorize the issue of any options, warrants or rights
      pro rata to all holders of its Common Shares entitling them to subscribe
      for or purchase any shares of stock of the Company or to receive any other
      rights;

(c)   The Company shall authorize the distribution pro rata to all holders of
      its Common Shares of evidences of its indebtedness or assets (excluding
      cash dividends or cash distributions paid out of retained earnings or
      retained surplus);

(d)   There shall occur any reclassification of the Common Shares, or any
      Combination (other than a Combination that does not result in a
      reclassification of the Common Shares); or

(e)   There shall occur the voluntary or involuntary liquidation, dissolution or
      winding up of the affairs of the Company;

      then, and in each of such cases, the Company shall deliver to the Holder
      at its last address appearing on the books of the Company, as promptly as
      practicable but in any event not less than 60 days prior to the applicable
      record date (or determination date) mentioned below, a notice stating, to
      the extent that such information is available: (i) the date on which a
      record is to be taken for the purpose of such dividend, distribution or
      rights, 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 or rights are to be determined, or (ii) the date on which
      such reclassification, Combination, liquidation, dissolution or winding up
      is expected to become effective; and (iii) 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 or other property deliverable
      upon such reclassification, Combination, liquidation, dissolution or
      winding up.

5.    Valid Issuance, Etc. The Company covenants and agrees that all of the
      Common Shares that may be issued upon the exercise of this Warrant will be
      duly authorized, validly issued and fully paid and nonassessable and free
      from all taxes, liens and charges with respect to the issue thereof to the
      Holder. The Company further covenants and agrees that during the period
      within which this Warrant may be exercised, the Company will at all times
      reserve such number of Common Shares as may be sufficient to permit the
      exercise in full of this Warrant.

6.    Registered Holder. Except as otherwise set forth herein, the Holder shall
      not be entitled by virtue of ownership of this Warrant to any rights
      whatsoever as a shareholder of the Company.

7.    Transfer. As set forth in the Agreement, the Company is not obligated to
      register this Warrant or the Common Shares issuable hereunder. This
      Warrant may not be sold, pledged, hypothecated or transferred at any time
      unless the Company shall have received an opinion of counsel to the effect
      that such transfer would not result in a violation of the provisions of
      the Securities Act or

<PAGE>

      applicable Canadian provincial securities laws. Any transfer of this
      Warrant to a transferee, in whole or in part, shall be effected upon
      surrender of this Warrant, duly endorsed (unless endorsement is waived by
      the Company), at the principal office or agency of the Company. If this
      Warrant is being sold, pledged, hypothecated or otherwise transferred, the
      Company shall issue a new Warrant registered in the name of the designated
      transferee(s). If the right to acquire less than all of the Common Shares
      issuable upon the exercise hereof is being sold, pledged, hypothecated or
      otherwise transferred, the Company shall issue a new Warrant, in each case
      for the appropriate number of Common Shares, registered in the name of the
      Holder and the designated transferee(s), as applicable. Common Shares of
      the Company issued upon the exercise hereof may not be sold, pledged,
      hypothecated or otherwise transferred at any time unless the Company shall
      have received an opinion of counsel to the effect that such transfer would
      not result in a violation of the Securities Act or applicable Canadian
      provincial securities laws.

8.    Confirmatory Notices; Restatements. The Company will promptly, upon
      Holder's request from time to time, confirm to Holder in writing the
      number of Common Shares that it is then entitled to purchase upon the
      exercise of this Warrant and the Exercise Price then in effect. In
      addition, the Company will on Holder's request and against delivery of
      this Warrant from time to time issue to Holder an amended and restated
      Warrant to reflect any adjustments theretofore made in the number of
      Common Shares then subject hereto and the Exercise Price.
