In order to allow Treasure Mountain to be governed by the corporate laws of a state whose corporate laws are well-defined and well understood by investors, Treasure Mountain has organized Delaware Subsidiary for the purpose of effecting the merger of Treasure Mountain with and into Delaware Subsidiary (the "Reincorporation Merger") pursuant to the terms and subject to the conditions set forth herein. Delaware Subsidiary, a Delaware corporation, will survive the Reincorporation Merger. D. The parties to this Plan of Merger desire to merge into a single corporation pursuant to Section 253 of the General Corporation Law of Delaware (the "DGCL") and Section 92A.100 of the Nevada General Corporation Law (the "NGCL"). E. On September 29, 2004, Treasure Mountain consummated the transactions contemplated by the Merger Agreement and Plan of Reorganization, dated as of July 8, 2004, as amended (the "First Merger Agreement"), by and among Treasure Mountain, a wholly-owned subsidiary of Treasure Mountain ("Vyteris Mergerco"), and Vyteris, Inc., a Delaware corporation (the "Company"). Pursuant to the First Merger Agreement: (i) Vyteris Mergerco merged with and into the Company (the "First Merger"); (ii) the Company became a wholly-owned subsidiary of Treasure Mountain; (iii) each share of the Company' common stock, par value $.0001 per share ("Company Common Stock"), was automatically converted into the right to receive 4.19 (the "Conversion Number") shares of Treasure Mountain's common stock, par value $.001 per share ("Treasure Mountain Common Stock"); (iv) each share of the Company's Series C Convertible Preferred Stock, par value $.0001 per share ("Company Series C Preferred Stock"), was automatically converted into the right to receive one share of Treasure Mountain's Series B Convertible Preferred Stock, par value $.001 per share ("Treasure Mountain Series B Preferred Stock"), each such share of Treasure Mountain Series B Preferred Stock being convertible into a number of shares of Treasure Mountain Common Stock equal to (a) the number of shares of Company Common Stock into which one share of Company Series C Preferred Stock was convertible immediately prior to the effective time of the First Merger (the "First Effective Time") multiplied by (b) the Conversion Number; (v) each warrant theretofore granted by the Company entitling its holder to purchase shares of Company Common Stock (an "Existing Warrant") was converted into the right to receive a warrant to purchase shares of Treasure Mountain Common Stock (a "New Warrant"), the terms of such New Warrant being identical to the terms of the corresponding Existing Warrant, except that (a) the number of shares of Treasure Mountain Common Stock covered by the New Warrant equals the number of shares of Company Common Stock covered by the Existing Warrant multiplied by the Conversion Number and (b) the exercise price of the New Warrant equals the exercise price set forth in the corresponding Existing Warrant divided by the Conversion Number; and (vi) each option theretofore granted by the Company entitling its holder to purchase shares of Company Common Stock (an "Existing Option") was converted into the right to receive an option to purchase shares of Treasure Mountain Common Stock (a "New Option"), the terms of such New Option being identical to the terms of the corresponding Existing Option, except that (a) the number of shares of Treasure Mountain Common Stock covered by the New Option equals the number of shares of Company Common Stock covered by the Existing Option multiplied by the Conversion Number and (b) the exercise price of the New Option equals the exercise price set forth in the corresponding Existing Option divided by the Conversion Number. F. As recognized in the First Merger Agreement, as of the First Effective Time, Treasure Mountain did not have a sufficient number of authorized but unissued shares of Treasure Mountain Common Stock to cover the number of shares of Treasure Mountain Common issuable pursuant to the First Merger and did not have any authorized shares of preferred stock. The First Merger Agreement provided that: (i) to the extent that a stockholder of the Company was entitled to receive shares of Treasure Mountain Common Stock upon consummation of the First Merger but there were not sufficient shares of authorized Treasure Mountain Common Stock to deliver to such stockholder (the number of shares of Treasure Mountain Common Stock which such stockholder was entitled to receive, but did not receive, being referred to herein as the "Shortfall Number"), such stockholder would receive a rights certificate (a "Common Rights Certificate") entitling such stockholder to receive, upon consummation of the Reincorporation Merger, a number of shares of Delaware Subsidiary common stock, par value $.0001 per share ("Delaware Subsidiary Common Stock") equal to ten percent of the Common Shortfall Number; and (ii) to the extent that a stockholder of the Company was entitled to receive shares of Treasure Mountain Series B Preferred Stock upon consummation of the First Merger, such stockholder would receive a rights certificate (a "Series B Rights Certificate" and together with the Common Rights Certificate, the "Rights Certificates") entitling such stockholder to receive, upon consummation of the Reincorporation Merger, a number of shares of Delaware Subsidiary Series B Convertible Preferred Stock, par value $.0001 per share ("Delaware Subsidiary Series B Preferred Stock"), equal to the number of shares of Company Series C Preferred Stock held by such stockholder immediately prior to the First Effective Time, each such share of Delaware Subsidiary Series B Preferred Stock being convertible into a number of shares of Delaware Subsidiary Common Stock equal to ten percent of the number of shares of Company Common Stock into which one share of Company Series C Preferred Stock was convertible immediately prior to the First Effective Time multiplied by the Conversion Number.

Delaware Subsidiary shall be the surviving corporation (herein as such called the "Surviving Corporation"). 2. SECOND EFFECTIVE TIME.

STOCKHOLDER APPROVAL. Subsequent to the approval of this Plan of Merger by the Board of Directors of Treasure Mountain, Treasure Mountain shall submit the Reincorporation Merger to its stockholders for their approval pursuant to Section 92A.120 of the NGCL. Treasure Mountain, as the sole shareholder of Delaware Subsidiary, has approved this Plan of Merger and the Reincorporation Merger. 4. TERMS AND CONDITIONS.

CONVERSION OF STOCK AND RIGHTS CERTIFICATES. At the Second Effective Time: (a) Each share of Treasure Mountain Common Stock issued and outstanding immediately prior to the Effective Time shall, without any action on the part of the holder thereof, become and be converted into one tenth of a share of Delaware Subsidiary Common Stock. The shares of Treasure Mountain Common Stock so converted shall cease to exist as such, and shall exist only as shares of Delaware Subsidiary Common Stock.

In lieu of the issuance of any such fractional share, Delaware Subsidiary shall pay to each former holder of Treasure Mountain Common Stock who otherwise would be entitled to receive a fractional share of Delaware Subsidiary Common Stock pursuant to the Reincorporation Merger (aggregating first all shares owned of record by such holder) an amount in cash representing $3.00 multiplied by such fraction.

STATUS OF SECURITIES AFTER THE EFFECTIVE TIME. No exchange of certificates representing shares of Treasure Mountain Common Stock converted pursuant to Section 6 shall be required. From and after the Second Effective Time and until certificates representing such Treasure Mountain Common Stock are presented for exchange or registration of transfer, all such certificates shall be deemed for all purposes to represent the number of shares of Delaware Subsidiary Common Stock into which they were so converted. After the Second Effective Time, whenever certificates which formerly represented shares of Treasure Mountain Common Stock are presented for exchange or registration of transfer, the Surviving Corporation shall cause to be issued in respect thereof, certificates representing a number of shares of Delaware Subsidiary Common Stock equal to ten percent of the number of shares of Treasure Mountain Common Stock represented by the certificate so presented, together with cash in lieu of fractional shares. 8.
