OxyADF(tm)Tablets Development Update

The Company's lead product candidate, OxyADF(tm) tablets (formerly referred to by the Company as Product Candidate #2) is an immediate release tablet under development pursuant to an active IND on file with the U.S. Food and Drug Administration ("FDA"). During the first quarter of 2006, as a routine part of the development process for OxyADF(tm) tablets, at the Company's written request, the Company and the FDA convened a face-to-face End of Phase 2 meeting ("EOP2 Meeting") for OxyADF(tm) tablets. As part of the EOP2 Meeting, the Company and the FDA discussed, among other things, the laboratory and clinical studies completed by the Company to date relating to OxyADF(tm) tablets and the remaining laboratory and clinical studies anticipated to be completed prior to the submission of a 505(b)(2) NDA for OxyADF(tm) tablets. The Company believes the guidance provided by FDA at the EOP2 Meeting clarifies the remaining development requirements relating to the Company's proposed indication and contemplated labeling for OxyADF(tm) tablets. The FDA has confirmed in written correspondence to the Company that OxyADF(tm) is an appropriate product candidate for submission as a 505(b)(2) NDA.

To date the Company, in concert with its contract research organizations ("CROs") has completed one phase I clinical study and one phase II clinical study relating to development of OxyADF(tm) tablets. The results from the phase I clinical study were used, among other things, to guide the formulation of the OxyADF(tm) tablets used in the phase II clinical study. Results from the phase II clinical study suggest that at the anticipated recommended therapeutic doses in normal subjects, OxyADF(tm) tablets will provide a side effects profile similar to the same opioid active ingredient formulated in a tablet without the Company's Aversion(r) Technology. The Company intends to use the data from such clinical studies in its 505(b)(2) NDA submission for OxyADF(tm) tablets.

The Company, in concert with an independent clinical CRO, has completed a pilot and a pivotal bioequivalence study for OxyADF(tm) tablets. The pivotal bioequivalence study used tablets from batches manufactured by the Company at a scale of sufficient size to fulfill the FDA's requirements for a 505(b)(2) NDA submission. The final report from the CRO for the pivotal bioequivalence study confirms that OxyADF(tm) tablets are bioequivalent to the applicable reference listed drug. The Company intends to use such data in its 505(b)(2) NDA submission for OxyADF(tm) tablets.

In addition, the Company, in concert with an independent laboratory CRO, completed a pivotal study to assess certain physical/chemical properties of OxyADF(tm) using tablets from batches manufactured by the Company at a scale of sufficient size to fulfill the FDA's requirements for a 505(b)(2) NDA submission. The final report from this pivotal laboratory study confirms that extracting the active opioid ingredient from OxyADF(tm) tablets in a form which may be administered via intravenous injection is substantially more difficult than extracting the active opioid ingredient from several currently marketed opioid-based commercial products. The Company intends to utilize the data from this pivotal laboratory study in its 505(b)(2) NDA submission for OxyADF(tm).

To receive marketing authorization for commercial distribution in the United States, OxyADF(tm) tablets and any drug product formulated with the Aversion(r) Technology will require the development, compilation, submission and filing of a NDA and approval of such application by the FDA. Estimating the dates of completion of laboratory and clinical development, and the costs to complete development, of the Company's product candidates, including OxyADF(tm) tablets, would be highly speculative, subjective and potentially misleading. Pharmaceutical products require significant time to research, develop and commercialize. The Company expects to reassess its future research and development plans based on the review of data received from current research and development activities and future guidance from the FDA. The cost and pace of future research and development activities are linked and subject to change. At this stage there can be no assurance that any of the Company's research and development efforts, including those for OxyADF(tm), will lead to a 505(b)(2) NDA submission or that if NDA submissions are made with the FDA, that any such submission will be approved by the FDA.

Commercial Strategy Update

To generate revenue, the Company plans to enter into development and commercialization agreements with strategically focused pharmaceutical company partners (the "Partners") providing that such Partners license OxyADF(tm) tablets and other product candidates utilizing the Aversion(r) Technology and further develop, register and commercialize multiple formulations and strengths of such product candidates. The Company expects to receive milestone payments and a share of profits and/or royalty payments derived from the Partners' sale of products incorporating the Aversion(r) Technology. Future revenue, if any, would be derived from licensing fees, milestone payments and a share of profits and/or royalty payments relating to our Partners' sale of products incorporating the Aversion(r) Technology. To date, the Company does not have any executed collaborative agreements with Partners nor can there be any assurance that the Company will successfully enter into such collaborative agreements in the future.

Cash Reserves Update

As of February 1, 2006, the Company had cash and cash equivalents of approximately $647,000. The Company estimates its current cash reserves will be sufficient to fund the development of OxyADF(tm) tablets and related operating expenses through mid-to-late March, 2006. To continue operating thereafter, the Company must raise additional financing or enter into appropriate collaboration agreements with third parties providing for cash payments to the Company. No assurance can be given that the Company will be successful in obtaining any such financing or in securing collaborative agreements with third parties on acceptable terms, if at all, or if secured, that such financing or collaborative agreements will provide for payments to the Company sufficient to continue funding operations. In the absence of such financing or third-party collaborative agreements, the Company will be required to scale back or terminate operations and/or seek protection under applicable bankruptcy laws.
