BIOANALYTICAL SYSTEMS, INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Amounts in thousands, except per share data)
(Unaudited)

1. Description of the Business and Basis of Presentation

Bioanalytical Systems, Inc. and its subsidiaries (the “Company” or “BASi”) engage in laboratory services and other services related to pharmaceutical development. We also manufacture scientific instruments for medical research, which we sell with related software for use in industrial, governmental and academic laboratories. Our customers are located throughout the world.

We have prepared the accompanying unaudited interim condensedconsolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States (“GAAP”), and therefore should be read in conjunction with our audited consolidated financial statements, and the notes thereto, included in our Form 10-K for the year ended September 30, 2006. In the opinion of management, the condensed consolidated financial statements for the three months ended December 31, 2006 and 2005 include all adjustments which are necessary for a fair presentation of the results of the interim periods and of our financial position at December 31, 2006. The results of operations for the three months ended December 31, 2006 are not necessarily indicative of the results to be expected for the year ending September 30, 2007.

All amounts in the condensed consolidated financial statements and the notes thereto are presented in thousands, except for share and per share data or where otherwise noted.

2. Stock Based Compensation

At December 31, 2006, we had stock-based employee and outside director compensation plans, which are described more fully in Note 8 in the Notes to the Consolidated Financial Statements in our Form 10-K for the year ended September 30, 2006. All options granted under these plans had an exercise price equal to or greater than the market value of the underlying common stock on the date of grant. Effective October 1, 2005, we began expensing the estimated fair value of stock options over the vesting periods of the grants, in accordance with Financial Accounting Standard 123 (Revised). Utilizing Modified Prospective Application, we expensed that portion of the estimated fair value of awards at grant date related to the outstanding options that vested during the period. The assumptions used are detailed in Note 1(f) to our financial statements in our Annual Report on Form 10-K for the year ended September 30, 2006. This resulted in compensation expense of $43 with no tax benefit in the quarter ended December 31, 2006, and compensation expense of $67 and a related deferred tax benefit of $23 in the quarter ended December 31, 2005.

There were no options granted in the fiscal year ended September 30, 2006. The assumptions used in computing our stock based compensation expense for options granted in the three months ended December 31, 2006 were as  follows:

Risk-free interest rate	4.65%
Dividend yield	0.00%
Volatility factor of the expected market
price of the Company’s common stock	0.623
Expected life of the options (years)	6.9 — 7.7

3. Income (loss) per share

We compute basic income/(loss) per share using the weighted average number of common shares outstanding. We compute diluted income per share using the weighted average number of common and potential common shares outstanding. Potential common shares include the dilutive effect of shares issuable upon exercise of options to purchase common shares. Shares issuable upon conversion of convertible subordinated debt have not been included

6

as they were not dilutive. No shares issuable upon exercise of options or conversion of debt are included in the computation of loss per share in 2005 as they are anti-dilutive.

The following table reconciles our computation of basic income/(loss) per share to diluted income/(loss) per share:

	Three Months Ended December 31,
	2006		2005

5. Segment Information

We operate in two principal segments - research Services and research Products. Our Services segment provides research and development support on a contract basis directly to pharmaceutical companies. Our Products segment provides liquid chromatography, electrochemical and physiological monitoring products to pharmaceutical companies, universities, government research centers and medical research institutions. Our accounting policies in these segments are the same as those described in the summary of significant accounting policies found in Note 1 to Consolidated Financial Statements in our annual report on Form 10-K for the year ended September 30, 2006.

Corporate expenses		(226	)		(256	)
Income (loss) before income taxes	$	503		$	(1,169	)

6. Income Taxes

We have provided income tax benefits on our domestic losses based on our expected annual effective rate of taxes for the fiscal year. In the three months ended December 31, 2006 we did not provide income taxes on foreign earnings due to the availability of net operating loss carryforwards to offset our taxable income, which have not previously been recognized for financial statement purposes.

7. Stock Option Plans

The Company established an Employee Stock Option Plan whereby options to purchase the Company’s common shares at fair market value at date of grant can be granted to our employees. Options granted become exercisable in four equal annual installments beginning two years after the date of grant. This plan terminates in fiscal 2008.

The Company also established an Outside Director Stock Option Plan whereby options to purchase the Company’s common shares at fair market value at date of grant can be granted to outside directors. Options granted become exercisable in four equal annual installments beginning two years after the date of grant. This plan terminates in fiscal 2008.

Options in both plans expire the earlier of ten years from grant date or termination of employment.

A summary of our stock option activity and related information for the three months ended December 31, 2006 is as follows:

	Options		Weighted average exercise price
Outstanding - beginning of period	403,878		$	4.98
Exercised	(17,000	)		4.58
Granted	20,000			5.19
Terminated	(29,500	)		4.79
Outstanding - end of period	377,378		$	5.04
Weighted grant date fair values			$	3.44

8

The intrinsic values of options exercised in the three months ended December 31, 2006 were $10. We received $76 from their exercise, for which no tax benefit was recognized. The options on the 377,378 shares outstanding at December 31, 2006 had an aggregate intrinsic value of $226 and a weighted average contract term of 6.4 years.

A summary of non-vested options for the three months ended December 31, 2006 is as follows:

	Number		Weighted Average Grant Date Fair Value
Non-vested options, beginning of period	278,378		$	3.75
Granted	20,000			5.19
Vested	(17,500	)		3.54
Forfeited	(22,500	)		3.54
Non-vested options, end of year	258,378		$	3.43

At December 31, 2006, there were 119,000 shares vested, all of which were exercisable. The weighted average exercise price for these shares was $5.29 per share; the aggregate intrinsic value of these shares was $72 and the weighted average remaining term was 6.0 years.

At December 31, 2006, there are 309,875 shares available for grants under the two plans.

The following applies to options outstanding at December 31, 2006:

Range of exercise prices		Number outstanding at December 31, 2006		Weighted average remaining contractual life (years)			Weighted average exercise price			Number exercisable at December 31, 2006		Weighted average exercise price

$	4.96 - 5.74		200,378		8	.28		5	.33		37,500		5	.69
$	7.18 - 8.00		17,000		0	.90		8	.00		17,000		8	.00

At December 31, 2006, we had $437 of compensation expense to be recognized for non-vested options with a weighted average vesting period of 3.03 years.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Form 10-Q may contain “forward-looking statements,” within the meaning of Section 27A of the Securities Act of 1933, as amended, and/or Section 21E of the Securities Exchange Act of 1934, as amended. Those statements may include, but are not limited to, discussions regarding BASi’s intent, belief or current expectations with respect to (i) BASi’s strategic plans; (ii) BASi’s future profitability; (iii) BASi’s capital requirements; (iv) industry trends affecting the Company’s financial condition or results of operations; (v) the Company’s sales or marketing plans; or (vi) BASi’s growth strategy. Investors in BASi’s Common Shares are cautioned that reliance on any forward-looking statement involves risks and uncertainties, including the risk factors contained in BASi’s annual report on Form 10-K for the year ended September 30, 2006. Although the Company believes that the assumptions on which the forward-looking statements contained herein are based are reasonable, any of those assumptions could prove to be inaccurate, and as a result, the forward-looking statements based upon those assumptions also could be incorrect. In light of the uncertainties inherent in any forward-looking statement, the inclusion of a forward-looking statement herein should not be regarded as a representation by the Company that BASi’s plans and objectives will be achieved.

All dollar amounts presented in this discussion and analysis are presented in thousands, except per share data.

GENERAL

The business of Bioanalytical Systems, Inc. is very much dependent on the level of pharmaceutical and biotech companies’ efforts in new drug discovery and approval. Our Services segment is the direct beneficiary of these efforts, through outsourcing of laboratory and analytical needs, and our Products segment is the indirect beneficiary, as increased drug development leads to capital expansion, providing opportunities to sell the equipment we produce and the consumable supplies we provide that support our products.

In our Annual Report on Form 10-K for the year ended September 30, 2006, we commented on the impacts and anticipated impacts developments in the pharmaceutical industry have on our businesses, as well as some of the potential risks. Those comments are still applicable, and are found under “General” in Part I, Item 2 of that report.

(a) Percentage of service and product revenues, respectively.

Three Months Ended December 31, 2006 Compared to Three Months Ended December 31, 2005

Service and Product Revenues

We increased our revenues in our first fiscal quarter of the current year by $1,040, or 11% over the comparable quarter last year. In our Service segment, revenue from our bioanalytical services increased $1.0 million (a 25% increase), toxicology revenues increased $0.6 million (a 32% increase), offset by a decrease of $0.5 million in our Baltimore clinical research unit (a 33% decrease). The decline in our Baltimore clinical research unit was due to the loss of a significant customer in our second fiscal quarter of 2006. This facility also had a strong quarter in the comparable period in the last fiscal year, which impacts the comparison of comparable periods. The improvements in our bioanalytical services and toxicology operations reflect a continued healthy market for those services, as well as successful sales efforts. Product segment revenues had a decline of $29, or 1%, from the comparable period last year. Our Culex automated pharmacology systems had improved sales compared to the first quarter of fiscal 2006, offset by declines in our more mature products.

Cost of Revenues

Our cost of Service revenues as a percentage of Service revenues decreased to 76.9% in the current quarter, compared to 77.8% for the same period last year. A substantial portion of our cost of productive capacity (personnel, facilities and laboratory equipment) is relatively fixed, resulting in a declining cost of services as a percentage of sales as we increase revenues. As announced in September 2006, we reduced the number of personnel throughout our organization in order to reduce costs. As a result, Service revenues increased $1,069, our related costs of Service revenues increased $758, improving our margin as a percentage of sales. Included in our cost of service revenue in the quarter ended December 31, 2006 is a cost accrual of $325 for costs to be incurred for repeating a study, without which we would have had further margin improvement. Our cost of Product revenue as a percentage of Product revenue is predominately determined by production volume. Although sales of Product in the current quarter were similar to the first quarter of the prior year, manufacturing activity was reduced, resulting in larger unabsorbed manufacturing costs, which were charged to cost of Product revenue, resulting in an increase in cost as a percentage of Product revenue, 38.5% this quarter compared to 36.3% in the same quarter last year.

11

Operating Expenses

Our selling expenses decreased by $54 (7%) in our first fiscal quarter compared to the same quarter in the prior year, which was the result of decreased travel and trade show expenses. Research and development expenses decreased by $84 (19%) in the first fiscal quarter compared to the comparable period last year as a result of our reduction in personnel in September 2006. General and administrative expenses for the three months ended December 31, 2006 decreased 44% to $1,622 from $2,887 for the three months ended December 31, 2005. This decrease was the result of several factors: 1) our September 2006 reduction in personnel, 2) the reduction in amortization expense in the current period due to the impairment charge for our Baltimore clinic recorded in the third quarter of fiscal 2006, 3) a change to heavier reliance on “as needed” personnel in our Baltimore clinic reduced the excess costs that were absorbed in general and administrative expenses, and 4) our efforts to contain all other costs in the current quarter. This reduction occurred while we increased our salary costs for our new Chief Executive Officer, who began with us at the beginning of the current quarter.

Other Expense

Our interest expense decreased $17 (7%) to $241 in the current fiscal quarter from $258 in the comparable quarter of the prior year. The decrease is attributable to lower levels of borrowing in the current year. Although our revolving credit facility has a floating interest rate which has increased since last year, we had no outstanding borrowings in the current quarter. Our long-term debt and capital leases were at the same interest rates in the comparable periods.

Income Taxes

As a result of our loss in our Baltimore clinic, we experienced an overall loss on domestic operations in the three months ended December 31, 2006. We computed our tax benefit using an overall effective tax rate of 41.5% on domestic losses, which is our estimate of our combined federal and local tax rates for the current year. We were able to utilize tax loss carryforwards available on our foreign earnings and therefore provided no related income tax expense.

Net Income (Loss)

As a result of the above factors, we had earnings of $556 ($.11 per share both basic and diluted) in the quarter ended December 31, 2006, compared to a loss of $716 ($.15 loss per share, both basic and diluted) in the same period last year. The computation of average outstanding shares in the current period included dilutive options, whereas options were not included in the computation of diluted earnings in the similar period last year as they were anti-dilutive. The effect of conversion of our outstanding convertible subordinated debentures was anti-dilutive in both years.

LIQUIDITY AND CAPITAL RESOURCES

Comparative Cash Flow Analysis

Since its inception, BASi’s principal sources of cash have been cash flow generated from operations and funds received from bank borrowings and other financings. At December 31, 2006, we had cash and cash equivalents of $1,863 compared to cash and cash equivalents of $1,647 at September 30, 2006. Approximately 14% of our cash balances were in the U.K. We monitor our U.K. cash needs to avoid currency conversion costs, which in the current interest rate environment can exceed interest.

Our net cash generated by operating activities was $1,157 for the three months ended December 31, 2006. This was the result of the earnings for the quarter to which is added our non-cash charges for depreciation and amortization, plus good collections on our receivables during the period. The impact on cash flow of other changes in operating assets and liabilities, net, was not material.

Net cash used by investing activities increased to $268 for the three months ended December 31, 2006 from $146 for the three months ended December 31, 2005 as a result of equipment purchases. We paid $563 of principal on our long-term debt and capital leases in the current quarter.

12

Capital Resources

We have a $6,000 revolving credit agreement with a commercial bank which extends until December 31, 2007. We may utilize up to that amount based upon our qualifying inventory and accounts receivable.

We have an outstanding letter of credit securing our lease on our Baltimore facility for $2,000. This letter of credit was reduced under its terms to $1,000 in January 2007, and expires in January 2008. This letter of credit reduces our amounts available under our revolving credit facility by the balance outstanding.

We expect our total capital additions in fiscal 2007 to be in the range of $1,000 to $1,200, which we expect to fund from operating cash flow.

Liquidity

We do not foresee the need to borrow extensively under our revolving credit agreement to finance current operations, unless we experience rapid growth of new business, which may necessitate borrowings to finance the buildup of receivables and inventory.

At December 31, 2006, we had $1,863 in cash, and $1,760 of available borrowings under our revolving credit facility.

Our revolving line of credit expires December 31, 2007. The maximum amount available under the terms of the agreement is $6,000 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 plus 50 basis points, or at the LIBOR rate plus 325 basis points, at our election. We pay a fee equal to 37.5 basis points on the unused portion of the line of credit. We have certain financial ratio covenants in our loan agreement, all of which were met in the quarter ended December 31, 2006.

13

We are required to make cash payments in the future on debt and lease obligations. The following table summarizes BASi’s contractual term debt, lease obligations and other commitments at December 31, 2006 and the effect such obligations are expected to have on our liquidity and cash flows in the periods ending September 30:

For further details on our indebtedness, see Note 6 to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended September 30, 2006.

The covenants in the Company’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 the Company can borrow to fund future operations, acquisitions and capital expenditures. Based on our current business activities, we believe cash generated from our operations and amounts available under our existing credit facilities and cash on hand, will be sufficient to fund the Company’s working capital and capital expenditure requirements for the foreseeable future. In January, 2008 our subordinated notes of $3,999 from a 2003 acquisition become due. We are exploring various alternatives to fund that obligation.

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. Borrowings under the Revolving Credit Agreement between BASi and National City Bank dated January 4, 2005 bear interest at a rate of either the bank’s prime rate plus 50 basis points, or at the LIBOR rate plus 325, at BASi’s option. We have fixed our interest rate on our mortgage debt through May, 2007.

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 exchange rates. The effect of movements in the exchange rates was not material to the consolidated operating results of BASi in fiscal years 2006 and 2005. 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, the Company’s Chief Executive Officer and Chief Financial Officer believe that the Company’s disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) were effective as of December 31, 2006 to ensure that information required to be disclosed by the Company in this Form 10-Q was recorded, processed, summarized and reported within the time periods specified by the Securities and Exchange Commission’s rules and forms.

There were no significant changes in the Company’s internal controls or other factors that could significantly affect those controls subsequent to the date of their evaluation, which was completed as of September 30, 2006.

ARTICLEI.

Records Pertaining to Share Ownership

Section 1.1. Recognition of Shareholders.  Bioanalytical Systems, Inc. (the “Corporation”) is entitled to recognize a person registered on its books as the owner of shares of the Corporation as having the exclusive right to receive dividends and to vote those shares, notwithstanding any other person’s equitable or other claim to, or interest in, those shares.

Section 1.2. Transfer of Shares.  Shares are transferable only on the books of the Corporation, subject to any transfer restrictions imposed by the Articles of Incorporation, these Bylaws, or an agreement among shareholders and the Corporation.  Shares may be so transferred upon presentation of the certificate representing the shares, endorsed by the appropriate person or persons, and accompanied by (a) reasonable assurance that those endorsements are genuine and effective, and (b) a request to register the transfer.  Transfers of shares are otherwise subject to the provisions of the Indiana Business Corporation Law (the “Act”), Article 8 of the Indiana Uniform Commercial Code and federal securities laws.

Section 1.3. Certificates.  Each shareholder is entitled to a certificate signed (manually or in facsimile) by the President or a Vice President and the Secretary or an Assistant Secretary, setting forth (a) the name of the Corporation and that it was organized under Indiana law, (b) the name of the person to whom issued, (c) the number, class, and series of shares represented, and (d) a conspicuous statement that the Corporation will furnish to the holder of the certificate on request, in writing, and without charge, a summary of the designations, relative rights, preferences, and limitations applicable to each such class of shares, and the variations in rights, preferences, and limitations determined for each series within a class (and the authority of the Board of Directors to determine variations for future series).  The Board of Directors shall prescribe the form of the certificate.

Section 1.4. Lost or Destroyed Certificates.  A new certificate may be issued to replace a lost or destroyed certificate.  Unless waived by the Board of Directors, the shareholder in whose name the certificate was issued shall make an affidavit or affirmation of the fact that the certificate is lost or destroyed, shall advertise the loss or destruction in such manner as the Board of Directors may require, and shall give the Corporation a bond of indemnity in the amount and form which the Board of Directors may prescribe.

ARTICLEII.

Meetings of the Shareholders

Section 2.1. Annual Meetings.  Annual meetings of the shareholders shall be held on the second Monday in February of each year, or on such other date as may be designated by the Board of Directors.

Section 2.2. Special Meetings.  Special meetings of the shareholders may be called by the President or by the Board of Directors.  Special meetings of the shareholders shall be called upon delivery to the Secretary of the Corporation of one or more written demands for a special meeting of the shareholders describing the purposes of that meeting and signed and dated by the holders of at least 25% of all the votes entitled to be cast on any issue proposed to be considered at that meeting.

Section 2.3. Notice of Meetings.  The Corporation shall deliver or mail written notice stating the date, time, and place of any shareholders’ meeting and, in the case of a special shareholders’ meeting or when otherwise required by law, a description of the purposes for which the meeting is called, to each shareholder of record entitled to vote at the meeting, at such address as appears in the records of the Corporation and at least 10, but no more than 60, days before the date of the meeting.  A shareholders’ meeting shall be held at such place, either in or out of the State of Indiana, as may be specified by the Board of Directors in the respective notice for such meeting.

Section 2.4. Waiver of Notice.  A shareholder may waive notice of any meeting, before or after the date and time of the meeting as stated in the notice, by delivering a signed waiver to the Corporation for inclusion in the minutes.  A shareholder’s attendance at any meeting, in person or by proxy (a) waives objection to lack of notice or defective notice of the meeting, unless the shareholder at the beginning of the meeting objects to holding the meeting or transacting business at the meeting, and (b) waives objection to consideration of a particular matter at the meeting that is not within the purposes described in the meeting notice, unless the shareholder objects to considering the matter when it is presented.

Section 2.5. Record Date.  The Board of Directors may fix a record date, which may be a future date, for the purpose of determining the shareholders entitled to notice of a shareholders’ meeting, to demand a special meeting, to vote, or to take any other action.  A record date shall be at least 10, but not more than 70, days before the meeting or action requiring a determination of shareholders.  If the Board of Directors does not fix a-record date, the record date shall be the 10th day prior to the date of the meeting or other action.

Section 2.6. Voting by Proxy.  A shareholder may appoint a proxy to vote or otherwise act for the shareholder pursuant to a written appointment form executed by the shareholder or the shareholder’s duly authorized attorney-in-fact.  An appointment of a proxy is effective when received by the Secretary or other officer or agent of the Corporation authorized to tabulate votes.  The general proxy of a fiduciary is given the same effect as the general proxy of any other shareholder.  A proxy appointment is valid for 11 months unless otherwise expressly stated in the appointment form.

2

Section 2.7. Voting Lists.  Following the record date for a shareholders’ meeting, the Secretary shall prepare an alphabetical list of all shareholders entitled to notice of the meeting, arranged by voting group and within each voting group by class and series, and showing the address and number of shares held by each shareholder.  The list shall be kept on file at the principal office of the Corporation or at a place identified in the meeting notice in the city where the meeting will be held.  The list shall be available for inspection and copying by any shareholder entitled to vote at the meeting, or by the shareholder’s agent or attorney authorized in writing, at any time during regular business hours, beginning 5 business days before the date of the meeting through the meeting.  The list shall also be made available to any shareholder, or to the shareholder’s agent or attorney authorized in writing, at the meeting and any adjournment thereof.  Failure to prepare or make available a voting list with respect to any shareholder’s meeting shall not affect the validity of any action taken at such meeting.

Section 2.8. Quorum; Approval.  At any meeting of shareholders, a majority of the votes entitled to be cast on a matter by a voting group at the meeting constitutes a quorum of that voting group.  If a quorum of a voting group is present when a vote is taken, action on a matter is approved by that voting group if the votes cast in favor of the action exceed the votes cast in opposition to the action, unless a greater number is required by law, the Articles of Incorporation, or these Bylaws.  If more than one voting group is entitled to vote on a matter, approval by each voting group is required for the matter to be approved by the shareholders as a whole.
