Basis of Presentation	Note 1 – Basis of Presentation: The accompanying unaudited interim consolidated financial statements (“interim statements”) have been prepared pursuant to the rules and regulations for reporting on Form 10-Q. Accordingly, certain information and disclosures required by generally accepted accounting principles for complete financial statements are not included herein. The interim statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s latest Annual Report on Form 10-K. The results for the three month period ended October 31, 2015 may not be indicative of the results for the entire year. Interim statements are subject to possible adjustments in connection with the annual audit of the Company’s accounts for fiscal year 2016. In the Company’s opinion, all adjustments necessary for a fair presentation of these interim statements have been included and are of a normal and recurring nature. The Company has a limited history of operations and limited revenue to date. The Company has several product candidates that are in various research or early stages of pre-clinical and clinical development. There can be no assurance that the Company will be successful in obtaining regulatory clearance for the sale of existing or any future products or that any of the Company’s products will be commercially viable. Going Concern The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The Company has experienced negative cash flows from operations since inception and has an accumulated deficit of approximately $374 million and a working capital deficiency of approximately $8.4 million at October 31, 2015. The Company has funded its activities to date almost exclusively from debt and equity financings, as well as the sale of non-essential real estate assets in fiscal 2012 through the first quarter of fiscal 2014. The Company will continue to require substantial funds to continue research and development, including pre-clinical studies and clinical trials of its product candidates, and to commence sales and marketing efforts, if the U.S. Food and Drug Administration or other regulatory approvals are obtained. Management’s plans in order to meet its operating cash flow requirements include financing activities such as private placements of its common stock, preferred stock offerings, issuances of debt and convertible debt instruments. Management is also actively pursuing financial and strategic alternatives, including strategic investments and divestitures, industry collaboration activities and strategic partners. Management has sold its non-essential real estate assets to augment its cash position. These factors raise substantial doubt regarding the Company’s ability to continue as a going concern. There are no assurances that such additional funding will be achieved and that the Company will succeed in its future operations. The interim statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts of liabilities that might be necessary should the Company be unable to continue in existence. The Company’s inability to obtain required funding in the near future or its inability to obtain funding on favorable terms will have a material adverse effect on its operations and strategic development plan for future growth. If the Company cannot successfully raise additional capital and implement its strategic development plan, its liquidity, financial condition and business prospects will be materially and adversely affected, and the Company may have to cease operations.

In the Company’s opinion, all adjustments necessary for a fair presentation of these interim statements have been included and are of a normal and recurring nature.

The Company has a limited history of operations and limited revenue to date.

There can be no assurance that the Company will be successful in obtaining regulatory clearance for the sale of existing or any future products or that any of the Company’s products will be commercially viable.

Going Concern

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The Company has experienced negative cash flows from operations since inception and has an accumulated deficit of approximately $374 million and a working capital deficiency of approximately $8.4 million at October 31, 2015. The Company has funded its activities to date almost exclusively from debt and equity financings, as well as the sale of non-essential real estate assets in fiscal 2012 through the first quarter of fiscal 2014.

The Company will continue to require substantial funds to continue research and development, including pre-clinical studies and clinical trials of its product candidates, and to commence sales and marketing efforts, if the U.S. Food and Drug Administration or other regulatory approvals are obtained. Management’s plans in order to meet its operating cash flow requirements include financing activities such as private placements of its common stock, preferred stock offerings, issuances of debt and convertible debt instruments. Management is also actively pursuing financial and strategic alternatives, including strategic investments and divestitures, industry collaboration activities and strategic partners. Management has sold its non-essential real estate assets to augment its cash position.

These factors raise substantial doubt regarding the Company’s ability to continue as a going concern. There are no assurances that such additional funding will be achieved and that the Company will succeed in its future operations. The interim statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts of liabilities that might be necessary should the Company be unable to continue in existence.
