During 2001, BASi commenced construction to expand its preclinical facilities in Evansville, Indiana. Construction of these preclinical facilities is expected to be completed by the end of February, 2003, at a total cost of $3,500,000. During 2002, BASi began expanding its facilities in West Lafayette, Indiana. Construction on the West Lafayette facilities is expected to have a total cost of $4,000,000. BASi obtained bank financing for each of these construction projects.

On December 13, 2002, BASi acquired LC Resources, Inc. (“LCR”), a privately-held company based in Walnut Creek, California. BASi purchased all of the outstanding shares of LCR for $2,500,000, subject to adjustment for certain changes in net tangible assets of LCR. BASi is currently evaluating the changes in net tangible assets. BASi paid cash of $125,000 at closing, and the remainder of the purchase price will be paid through promissory notes issued by BASi, bearing interest at 10% per annum, and maturing on October 1, 2007. The holders of the notes will have the option to require BASi to repay up to 20% of the outstanding principal balance of the notes on each October 1 prior to maturity, commencing October 1, 2003. These notes are subordinated to senior bank debt.

On June 20, 2002, BASi and PharmaKinetics Laboratories, Inc. (“PKLB”) entered into a merger agreement that will result in PKLB becoming a wholly-owned subsidiary of BASi. In connection with the merger, BASi will issue 6% Subordinated Convertible Notes in an aggregate principal amount of approximately $4,000,000 to the holders of PKLB Class A Preferred shares. No principal payments will be due on these notes until 2008. No interest will be paid on the notes for one year after the date of issuance. The notes are convertible into BASi common shares at the option of the holder at any time after the first anniversary of the date of issuance at a price of $16.00 per share.

Between June and December, 2002, BASi loaned PKLB a total of $783,000 for working capital purposes. On November 14, 2002, PKLB executed a Secured Convertible Revolving Note in the principal amount of up to $925,000 payable to BASi to replace the existing notes payable to BASi and to allow PKLB to borrow additional amounts to cover short-term operating requirements. The note issued to BASi carries an annual interest rate of 8%, and all principal and accrued interest is due and payable on May 1, 2003. The outstanding principal amount of the note to BASi is convertible by BASi at any time into PKLB common stock at a price of $0.1585 per common share, which price represents the average of the closing prices for PKLB’s common shares as reported by NASDAQ for the twenty (20) trading days ended November 8, 2002. All PKLB common shares held by BASi as of the effective time of the merger will be cancelled. The note to BASi is secured by a security interest in favor of BASi in all of the assets of PKLB pursuant to a Security Agreement between PKLB, as debtor, and BASi, as secured party. PKLB Limited Partnership, a subsidiary of PKLB, guaranteed repayment of the note to BASi, pursuant to the terms of an Unconditional Guaranty dated as of November 14, 2002, and pledged certain real property located in Baltimore, Maryland to BASi as security for its guaranty pursuant to the terms of an Indemnity Deed of Trust.

One of BASi’s credit agreements (discussed below) limits the amount that can be loaned to PKLB prior to the closing of the merger to the amount of the Secured Convertible Revolving Note. If the merger is consummated, BASi expects to expend additional amounts to pay trade payables and other obligations of PKLB and to fund PKLB’s continuing operations. BASi intends to fund these expenses using cash from operations and borrowings under the line of credit. BASi’s credit agreement also requires BASi to sell the Baltimore, Maryland real property within 180 days following its acquisition of PKLB. BASi intends to use the net proceeds from the sale to pay down the line of credit. BASi management believes that the sale of the building will enable it to fund PKLB operations until such time as the cash flow generated from those operations becomes adequate to support the operations.

On October 29, 2002, BASi obtained new credit agreements with two different banks that completely refinanced and replaced all outstanding bank debt arrangements that were in place at September 30, 2002. These new credit agreements provide for a $6,000,000 revolving line of credit with a bank and a mortgage note and two construction term loans payable with another bank aggregating $10,000,000. Borrowings under these new credit agreements are collateralized by substantially all assets related to BASi’s operations, all common stock of BASi’s United States subsidiaries and 65% of the common stock of its non-United States subsidiaries, and the assignment of a life insurance policy on BASi’s Chairman and CEO. Under the terms of these credit agreements, BASi has agreed to restrict advances to foreign subsidiaries, limit additional indebtedness and capital expenditures as well as to comply with certain financial covenants outlined in the borrowing agreements. These financial covenants include: maintenance of a certain ratio of interest bearing indebtedness (not including subordinated debt) to earnings before income taxes, depreciation, amortization, and interest expense (“EBITDA”); maintenance of a certain ratio of total indebtedness to tangible net worth and subordinated debt; maintenance of a certain ratio of EBITDA to certain identified fixed charges; maintenance of a certain ratio of current assets to current liabilities; limits on the amount of capital expenditures that can be made using funds other than long-term indebtedness in a single fiscal year; and maintenance of a certain ratio of net cash flow to debt servicing requirements. These new credit agreements contain cross-default provisions. Details of each debt issue are discussed below.

–  11  –

BASi’s revolving line of credit expires September 30, 2005. The maximum amount available under the terms of the agreement is $6,000,000 with outstanding borrowings limited to the borrowing base as defined in the agreement. Interest accrues monthly on the outstanding balance at the bank’s prime rate to prime rate plus 125 basis points, or at the Eurodollar rate plus 200 to 350 basis points, as elected by BASi, depending upon the ratio of BASi’s interest bearing indebtedness (less subordinated debt) to EBITDA. BASi pays a fee equal to 25 to 50 basis points, depending upon the same financial ratio, on the unused portion of the line of credit.

BASi has a $5,410,000 commercial mortgage with a bank. The mortgage note requires 119 monthly principal payments of $22,542 plus interest, followed by a final payment for the unpaid principal amount of $2,727,502 due November 1, 2012. Interest is charged at the prime rate. BASi has a $2,250,000 construction loan with the same bank, which expires November 1, 2012. The loan requires interest payments only until completion of the project in West Lafayette, Indiana. Interest is charged at the prime rate. BASi also has another construction loan for $2,340,000 with the same bank, which expires May 1, 2008. This loan also requires interest payments only until completion of the project in Evansville, Indiana and interest is also charged at the prime rate. On November 15, 2002, BASi obtained a $1,500,000 lease line for equipment with a bank. At December 31, 2002, $1,090,000 was utilized under the terms of operating leases requiring 60 payments of $17,820.

To obtain the foregoing new credit agreements, BASi entered into an agreement with Periculum Capital Company, LLC (“Periculum”). Under the terms of the agreement, BASi paid $300,000 in fees to Periculum upon closing of the refinancing.

Liquidity
BASi is required to make cash payments in the future on debt and lease obligations. The following table summarizes BASi’s contractual term debt and lease obligations at December 31, 2002 (reflective of the issuance of notes payable to acquire LCR) and the effect such obligations are expected to have on its liquidity and cash flows in future periods (amounts in thousands).

                                    Payments due for fiscal years ending September 30:

BASi’s borrowings under its revolving line of credit for working capital needs, borrowings to fund capital expenditures using construction loans and the 6% subordinated notes payable that may be issued in connection with the merger with PKLB will each affect BASi’s liquidity and cash flows in future periods. These obligations are not reflected in the above schedule. The covenants in BASi’s credit agreement requiring the maintenance of certain ratios of interest bearing indebtedness (not including subordinated debt) to EBITDA and net cash flow to debt servicing requirements may restrict the amount BASi can borrow to fund future operations, acquisitions and capital expenditures.

During the first quarter, BASi borrowed additional funds to continue construction on its West Lafayette expansion project. In order to better assure compliance with the covenants in the credit agreement, construction on this project has been delayed and management does not expect to make significant borrowings in connection with this project until cash flow improves. BASi has formulated and begun to implement a plan to reduce debt and improve its cash flow to better enable it to satisfy the credit agreement covenants in the future. The plan includes, but is not limited to, headcount reductions and other cost-saving measures at its West Lafayette and McMinville, Oregon facilities, the sale of real estate assets in West Lafayette, and the delay of construction of its West Lafayette expansion project. Further, BASi believes compliance with loan covenants will be achieved and will take necessary action, including deferral of the PKLB acquisition, if deemed necessary, to remain compliant.

BASi intends to issue additional subordinated debt of approximately $4,000,000 in connection with the contemplated acquisition of PKLB. This indebtedness will not require any payments of principal or interest by BASi during the first year after it is issued, and will not affect BASi’s compliance with the leverage covenant in its credit agreement. However, as discussed above, BASi will use cash from operations and amounts available under its credit agreement to pay trade payables and other obligations of PKLB and to fund PKLB’s future operations. To offset these requirements, BASi intends to sell a building owned by PKLB, located in Baltimore, Maryland and to apply the net proceeds from the sale to reduce amounts outstanding under the credit agreement.

–  12  –

Based on its current business activities, BASi believes cash generated from its operations, amounts available under its existing bank line of credit and credit facility, and the proposed action plan will be sufficient to fund BASi’s short and long-term working capital and capital expenditure requirements for the foreseeable future and through September 30, 2003.

Please refer to the Notes of Consolidated Financial Statements for a discussion of recently issued accounting standards.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

BASi’s primary market risk exposure with regard to financial instruments is changes in interest rates. The credit agreement between BASi and The Provident Bank dated October 29, 2002 bears interest at a rate of either the bank’s prime rate plus 0 to 125 basis points, or at Eurodollar rate plus 200 to 350 basis points, depending in each case upon the ratio of BASi’s interest-bearing indebtedness (less subordinated debt) to EBITDA, at BASI’s option. BASi also has construction loans and a commercial mortgage which bear interest at the prime rate. Historically, BASi has not used derivative financial instruments to manage exposure to interest rate changes. BASi estimates that a hypothetical 10% adverse change in interest rates would not affect the consolidated operating results of BASi by a material amount.

BASi operates internationally and is, therefore, subject to potentially adverse movements in foreign currency rates change. The effect of movements in the exchange rates was not material to the consolidated operating results of BASi in fiscal years 2002 and 2001. BASi estimates that a hypothetical 10% adverse change in foreign currency exchange rates would not affect the consolidated operating results of BASi by a material amount.

ITEM 4.    CONTROLS AND PROCEDURES

Based on their most recent evaluation, which was completed within 90 days of the filing of this Form 10-Q, BASi’s Chief Executive Officer and Chief Financial Officer believe BASi’s disclosure controls and procedures (as defined in Exchange Act Rules 13a-14 and 15d-14) are effective in timely alerting BASi’s management to material information required to be included in this Form 10-Q and other Exchange Act filings. There were no significant changes in BASi’s internal controls or other factors that could significantly affect these controls subsequent to the date of their evaluation, and there were no significant deficiencies or material weaknesses which required corrective actions.
