     (a)  VOTING

          Holders of common shares shall be entitled to receive notice of and to

          have one vote for each common share held at all meetings of the
          shareholders of the Corporation, except meetings at which only holders

          to vote separately.

     (b)  DIVIDENDS

          Subject to the prior rights of the holders of preferred shares and any
          other shares ranking senior to the common shares with respect to
          priority in the payment of dividends, the holders of common shares
          shall be entitled to receive dividends and the Corporation shall pay
          dividends thereon, as and when declared by the board of directors of
          the Corporation out of moneys properly applicable to the payment of
          dividends, in such amount and in such form as the board of directors
          of the Corporation may from time to time determine and all dividends
          which the board of directors of the Corporation may declare on the
          common shares shall be declared and paid in equal amounts per share on
          all common shares at the time outstanding.

     (c)  PARTICIPATION IN ASSETS ON DISSOLUTION

          In the event of the dissolution, liquidation 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, subject to the prior rights of
          the holders of the preferred shares and any other shares ranking
          senior to the common shares with respect to priority in the
          distribution of assets upon dissolution, liquidation, winding-up or
          distribution for the purpose of winding-up, the holders of the common
          shares shall be entitled to receive the remaining property and assets
          of the Corporation.


2.   10,000,000 preferred shares which shall have attached thereto the following
     preferences, rights, conditions, restrictions, limitations, or
     prohibitions:

     (a) DIRECTORS' AUTHORITY TO ISSUE IN ONE OR MORE SERIES

         The board of directors of the Corporation may issue the preferred
         shares at any time and from time to time in one or more series before
         the first shares of any particular series are issued, and shall fix the
         number of preferred shares in such series and, determine, subject to
         the limitations in the Articles, the designation, rights, privileges,
         restrictions and conditions attached to the shares of such series
         including without limitation, the rate or rates, amount or method or
         methods of calculation of dividends thereon, the time and place of
         payment of dividends, whether cumulative or non-cumulative or partially
         cumulative and whether such rate, amount or method of calculation shall
         be subject to change or adjustment in the future, the currency or
         currencies of payment of dividends, the priorities thereof in relation
         to other shares or the priorities of other shares in relation thereto,
         if any, the consideration and the terms and conditions of any purchase
         for cancellation, retraction or redemption rights, if any, the
         conversion or exchange rights attached thereto, if any, the voting
         rights attached thereto, if any, and the terms and conditions of any
         share purchase plan or sinking fund with respect thereto. Before the
         issue of the first shares of a series, the board of directors of the
         Corporation shall send to the Registrar, as defined in the Yukon
         Business Corporations Act, Articles of Amendment containing the
         description of such series including the designation, rights,
         privileges, restrictions and conditions attached thereto as determined
         by the board of directors of the Corporation.

     (b) RANKING OF PREFERRED SHARES

         No rights, privileges, restrictions or conditions attached to a series
         of preferred shares shall confer upon a series a priority in respect of
         voting dividends or return of capital over any other series of
         preferred shares then outstanding. The preferred shares shall be
         entitled to priority over the common shares of the Corporation and over
         any other shares of the Corporation ranking junior to the preferred
         shares with respect to the payment of dividends and the distribution of
         assets in the event of the liquidation, dissolution or winding-up of
         the Corporation, whether voluntary or involuntary, or any other
         distribution of the assets of the Corporation among its shareholders
         for the purpose of winding-up its affairs. If any cumulative dividends
         or amounts payable on a return of capital in respect of a series of
         preferred shares are not paid in full the preferred shares of all
         series shall participate rateably in respect of such dividends,
         including accumulations, of any, in accordance with the sums


         that would be payable on such shares if all such dividends were
         declared and paid in full, and in respect of any repayment of capital
         in accordance with the sums that would be payable on such repayment of
         capital if all sums so payable were paid in full, provided however,
         that in the event of there being insufficient assets to satisfy in full
         all such claims to dividends and return of capital, the claims of the
         holders of the preferred shares with respect to repayment of capital
         shall first be paid and satisfied and any assets remaining thereafter
         shall be applied towards the payment and satisfaction of claims in
         respect of dividends. After payment to the holders of preferred shares
         of each series of the amounts of dividends and capital payable in
         accordance with these provisions and the rights, privileges and
         restrictions attached to each series of preferred shares, the holders
         of preferred shares shall not be entitled to share in any further
         distribution of the property and assets of the Corporation. The
         preferred shares of any series may also be given such other
         preferences, consistent with the Articles, over the common shares and
         over any other shares raking junior to the preferred shares as may be
         determined in the case of such series of preferred shares.

     (c)  APPROVAL OF HOLDERS OF PREFERRED SHARES

          The rights, privileges, restrictions and conditions attaching to the
          preferred shares as a class may be added to, changed or removed but
          only with the approval of the holders of the preferred shares given as
          hereinafter specified.

          The approval of the holders of preferred shares to add to, change or
          remove any rights, privilege, restriction or condition attaching to
          the preferred shares as a class or to any other matter requiring the
          consent of the holders of the preferred shares as a class may be given
          in such manner as may then be required by law, subject to a minimum
          requirement that such approval shall be given by resolution passed by
          the affirmative vote of at least two-thirds of the votes cast at a
          meeting of the holders of preferred shares duly called for that
          purpose.  The formalities to be observed in respect of the giving of
          notice of any such meeting or any adjourned meeting and the conduct
          thereof shall be those from time to time required by the Yukon
          Business Corporations Act (as from time to time amended, varied or
          replaced) and prescribed in the Bylaws of the Corporation with respect
          to meetings of shareholders.  On every poll taken at a meeting of
          holders of preferred shares as a class, each holder entitled to vote
          thereat shall have one vote in respect of each preferred share held by
          him.


                                  SCHEDULE "B"

                             ULTRA PETROLEUM CORP.

   additional Directors of the Corporation to serve until the next annual

   exceed one third of the number of Directors who held office at the expiration
   of the last annual general meeting of the Corporation, provided that the
   total number of directors shall not exceed the maximum number of directors
   fixed pursuant to the Articles.
