Item 3.	Source and Amount of Funds or Other Consideration

	In acquiring $4,388,158 Common Shares owned by Composite, Composite expended approximately $138,182,745 (excluding commissions) of its working capital. In acquiring 2,974,800 Common Shares owned by Valence, Valence expended approximately $98,014,838 (excluding commissions) of its working capital. In acquiring listed call options exercisable for 25,000 Common Shares, Valence expended approximately $117,500 (excluding commissions) of its working capital. In acquiring 819 Common Shares owned by Synoptic, Synoptic expended approximately $27,477 (excluding commissions) of its working capital.

Item 4.	Purpose of Transaction

	Composite, Valence, and Synoptic made the purchases noted in Item 3 above for investment purposes. Composite, Valence, and Synoptic will review their investments in the Common Shares from time to time, and, subject to applicable law and regulation and depending upon certain factors, including, without limitation, the financial performance of the Issuer, the availability and price of the Common Shares or other securities related to the Issuer, and other general market and investment conditions, Composite, Valence, and Synoptic may determine to:

	●	acquire additional Common Shares through open market purchases or otherwise;

	●	sell, trade, engage in short selling of, hedge, or enter into any similar transactions with respect to the Common Shares through the open market or otherwise; or

	●	otherwise engage or participate in a transaction with the purpose or effect of changing or influencing the control of the Issuer.

	Such transactions may take place at any time and without prior notice. There can be no assurance, however, that any Reporting Person will take any such actions.

	As part of Composite’s, Valence’s, and Synoptic’s ongoing review of their investments in the Common Shares, Composite, Valence, and Synoptic will from time to time hold talks or discussions with, write letters to and respond to inquiries from various parties, including, without limitation, the Issuer’s Board of Directors, management or representatives, other shareholders and other persons or entities, regarding the Issuer’s affairs and strategic alternatives.

	Without limiting the generality of the foregoing, Composite has sent a letter to Mr. Peter Lankau, the Chief Executive Officer of the Issuer, dated July 27, 2007 (the “Issuer Letter”), expressing certain concerns with respect to the current share price of the Common Shares. The Reporting Persons believe that the true value of the Common Shares is being discounted due to (a) an inefficient capital structure at the Issuer, in the form of net cash on hand retained for a potential strategic acquisition transaction, (b) the Issuer’s publicly stated intention to diversify away from pain management through a strategic acquisition transaction, and (c) the perceived risk of genericization of the Issuer’s drug Lidoderm. The Reporting Persons believe that more effectively deploying the Issuer’s net cash position in the near-term could substantially improve its present and future valuation with no risk of impairing the ability to pursue a future acquisition transaction. The Reporting Persons believe the company should consider strategic alternatives prior to pursuing a transaction to diversify beyond pain management. The Reporting Persons also believe that the risk of genericization to Lidoderm’s business is overstated.

	The Reporting Persons have attached the Issuer Letter to this Schedule 13D as Exhibit 4.

	Based on the above-referenced Issuer Letter and other discussions or inquiries that Composite, Valence, and Synoptic may undertake from time to time, and subject to applicable law and regulation and depending upon certain factors, including, without limitation, the financial performance of the Issuer, the availability and price of the Common Shares or other securities related to the Issuer, and other general market investment conditions, Composite, Valence, and Synoptic may determine to pursue various strategic alternatives in respect of their investments in the Issuer. Such actions may include, without limitation, direct or indirect participation in the following:

	●		forming and conducting potential strategic developments and plans related to the Issuer;

	●		seeking representation on the Board of Directors of the Issuer;

	●		making recommendations to the Issuer’s Board of Directors and management of the Issuer concerning various business strategies, mergers, acquisitions, dispositions, dividend policy, capital structure, the provisions of the Issuer’s Articles of Incorporation or Bylaws or other matters;

	●		seeking to acquire control of the Issuer through a merger, proxy solicitation, tender offer, exchange offer or otherwise;

	●		restructuring and effecting other significant transactions with respect to the Issuer;

	●		participating in a “going-private” transaction;

	●		taking any other actions that could have the purpose or effect of directly or indirectly changing or influencing control of the Issuer; or

	●		providing financing for any of the foregoing.

	Such transactions may take place at any time and without prior notice. There can be no assurance, however, that the possible courses of action expressed in the immediately preceding sentence will be pursued or, if pursued, will be consummated by Composite, Valence, and Synoptic or any other Reporting Person.
