Howard, Lawson & Co. Two Penn Center Plaza Investment Banking Philadelphia, PA 19102 Corporate Finance 215 988-0010 215 568-0029 FAX May 17, 1999 Mr. Kenneth P. Brice Vice President of Finance Hydromer, Inc. 35 Industrial Parkway Somerville, NJ 08876-3518 Dear Mr. Brice: You have asked us to provide a valuation of the common stock (the "Shares") of Biosearch Medical Products, Inc. ("Biosearch") to assist Hydromer, Inc. ("Hydromer") in evaluating a possible acquisition of Biosearch. The effective date of the valuation is as of the date of our letter (the "Valuation Date"). Definition of Fair Market Value Fair market value is the price at which an asset would change hands between a willing buyer and a willing seller when the former is not under any compulsion to buy and the latter is not under any compulsion to sell, and both parties are able, as well as willing, to trade and are well informed about the asset and the market for that asset. The Situation Biosearch develops, manufactures, and markets products designed for medical and surgical applications. Biosearch's manufacturing is largely focused on applying hydrophilic coatings to intermittent urinary catheters. Biosearch holds an exclusive, worldwide, license to apply Hydromer(R), a patented coating technology to certain medical devices. Revenues for Biosearch have declined from $3.6 million in 1994 to $1.3 million in 1998. In addition, Biosearch has experienced net losses in the aggregate of $3.1 million for the fiscal years 1995 through 1998. Revenues for the three months ended March 31, 1999 were $218,401 compared to $604,117 for the same period a year ago. In addition, operating losses for the three months ended March 31, 1999 amounted to $191,035 compared to operating losses of $28,004 for the three months ended March 31, 1998. Biosearch Medical Products, Inc. Opinion Letter - -------------------------------------------------------------------------------- The Situation (continued) Hydromer is a polymer research and development company that develops polymeric complexes for commercial markets in the medical and industrial fields Hydromer owns several process and application patents for Hydromer(R) which is a polymeric substance that becomes extremely lubricious when wet, and a technique of grafting or applying this substance onto surfaces which consist of a broad variety of materials, including other polymers such as polyurethane, polyvinyl chloride, and silicone elastomers, ceramics and metals. Hydromer is considering acquiring Biosearch, which would allow Hydromer to funnel its chemical production through Biosearch. Accordingly, you have asked us to provide a valuation of the common stock of Biosearch to assist you in evaluating a possible acquisition of Biosearch. Factors Considered In arriving at our opinion of the fair market value of common stock of Biosearch as of the Valuation Date, we have considered all factors we deemed relevant, including the following: (1) The nature and history of Biosearch's business; (2) The general economic outlook and the outlook for the medical equipment industry; (3) The book value of Biosearch and the financial condition of the company; (4) The results of operations of Biosearch; (5) The dividend-paying capacity of Biosearch; (6) Whether or not Biosearch has goodwill or other intangible value; (7) Past transactions in Biosearch's common stock; and, (8) The market price of the stocks of corporations (listed on exchanges, NASDAQ or trading over-the-counter) engaged in the same or similar lines of business as Biosearch, where such stock is traded in a free and open market. A determination of fair market value depends upon the circumstances in each case. In forming our opinion, we considered these factors and concluded that certain factors are more significant indicators of value than others, but have not assigned mathematical weights to any of them in determining fair market value. - -------------------------------------------------------------------------------- Howard, Lawson & Co. 2 Biosearch Medical Products, Inc. Opinion Letter - -------------------------------------------------------------------------------- Materials Reviewed In arriving at our opinion, we have considered, among other things, the following information: (1) Audited financial statements of Biosearch for the years ended December 30, 1994 through December 31, 1998; (2) Audited financial statements of Biosearch for three months ended March 31, 1998 and the three months ended March 31, 1999; (3) Forecasted financial statements of Biosearch for the years ending December 31, 1999 through December 31, 2003 provided by Biosearch; (4) Publicly available financial and market information regarding certain companies we deemed comparable to Biosearch; and, (5) Information regarding the business and its prospects obtained in discussions with the managements of Hydromer and Biosearch. Relevant Factors Considered In forming our opinion as to the fair market value of Biosearch as of the Valuation Date, we considered all recognized valuation methodologies, placing emphasis on those methods used to estimate fair market value under the assumption of the Biosearch continuing as a going concern. Activities Conducted In arriving at our opinion of the fair market value of Biosearch, we conducted the following activities: 1. We performed an asset purchase analysis of Biosearch based on estimated fair market values of Biosearch's fixed and intangible assets. The management of Hydromer estimates that Biosearch's fixed assets have a fair market value of $50,000 and the intangible assets have a fair market value of $50,000. 2. We performed a discounted cash flow ("DCF") analysis based on management's forecasts of future earnings, adjusted to reflect the probability of a range of possible outcomes. We employed different probabilities of Biosearch meeting its forecasts, much in the same manner that a venture capital investor would use to analyze an investment in a development stage company. This method is referred to as The First Chicago Method. - -------------------------------------------------------------------------------- Howard, Lawson & Co. 3 Biosearch Medical Products, Inc. Opinion Letter - -------------------------------------------------------------------------------- Limiting Conditions or Assumptions We have relied on management's representations concerning Biosearch and on financial statements of Biosearch in forming our opinion of value. We have assumed the accuracy of all financial information reviewed. See the Methodology and Background exhibit of our report for a full description of assumptions and limiting conditions to our valuation opinion. Discussion As mentioned in The Situation section of our report, revenues for Biosearch declined from $3.6 million in 1994 to $1.3 million in 1998. In addition, revenues for the three months ended March 31, 1999 were $218,401 compared to $604,117 for the same period a year ago. Biosearch experienced net losses in the aggregate of $3. l million for the fiscal years 1995 through 1998. In addition, operating losses for the three months ended March 31, 1999 amounted to $191,035 compared to operating losses of $28,004 for the same period a year ago. Furthermore, shareholders' equity as of March 31, 1999 was $489,561 compared to $3.2 million as of December 31, 1994. See Exhibits 1 and 2 for a summary balance sheet and income statement of Biosearch. Asset Purchase In arriving at our opinion of the fair market value of Biosearch, we considered an asset purchase analysis of Biosearch based on estimated fair market values of Biosearch's fixed and intangible assets as of the Valuation Date. The management of Hydromer estimates that Biosearch's fixed assets have a fair market value of $50,000 and the intangible assets have a fair market value of $50,000. Assuming that Biosearch's net operating loss carryfowards are available to a buyer, they would have an estimated value of $250,000 to $300,000. On the basis of an asset purchase and excluding all liabilities, we believe the relevant range of values for Biosearch is $350,000 to $400,000 in the aggregate, or $0.16 per share to $0.18 per share. Discounted Cash Flow We also performed a DCF analysis based on management's forecasts of future earnings, adjusted to reflect the probability of a range of possible outcomes. We employed different probabilities of Biosearch meeting its forecasts, much in the same manner that a venture capital investor would use to analyze an investment in a development stage company. This method is referred to as The First Chicago Method. In preparing the DCF analysis to determine the net present value of the expected future cash flows of Biosearch, we first calculated a cost of capital for Biosearch. Our DCF analysis was based on projections provided by Biosearch to Hydromer. - -------------------------------------------------------------------------------- Howard, Lawson & Co. 4 Biosearch Medical Products, Inc. Opinion Letter - -------------------------------------------------------------------------------- Discussion (continued) Discounted Cash Flow (continued) In order to determine the net present value of the estimated cash flows, we first calculated a weighted average cost of capital ("WACC") for Biosearch. The WACC serves as an estimate of the required rate of return for an investment of similar risk and capital structure. In calculating the cost of capital of Biosearch, we calculated the estimated implied cost of equity based on multiples reflected in the values of comparable publicly traded companies. See Exhibits 3 and 4 for the financial and market data of the publicly traded guideline companies, respectively. Also, see Exhibit 5 for a comparison of Biosearch to the public guideline companies. The guideline companies cost of equity is readily determined by the use of the Gordon Growth Model. According to this methodology, the rate of return (k) is a function of a company's projected net income (I), market value (MV), and expected five year growth rate (g). K= I/MV + g In our calculation of the implied cost of equity, we determined the ratio of price, or market value, to projected net income, as shown in Exhibit 6. The 1999 projected net income-to-market value ratio is the inverse of the price-to-projected net income ratio. The cost of equity is then determined by adding the expected five-year growth rate to the projected net income-to-market value ratio. Only one of the seven-selected guideline companies had analysts' consensus five-year forecasted growth rates available. Using this methodology results in implied costs of equity of 42%. Biosearch did not have any interest-bearing debt as of the Valuation Debt, and therefore we used the implied cost of equity rather than a WACC. Exhibit 7 illustrates the calculation of the present value of forecasted net after-tax free cash flows over the forecasted period and the calculation of the present value of a residual value for Biosearch at the end of the forecast period assuming that Biosearch achieves approximately 41% of its forecast. In Exhibit 7, all cash flows of Biosearch have been discounted at 45%. We assumed that the cash flow of Biosearch will grow at an average rate of 5% over the long-term following the forecast period. Using a discount rate of 45%, our calculations resulted in a present value of the estimated cash flows for the fiscal years 1999 through 2003 of approximately $161,000. The present value of the post-year 2003 cash flows received in perpetuity, or residual value, is approximately $119,000. When these two amounts are added together, the total present value of future cash flows, or enterprise value, is $280,000. In order to determine the equity value of Biosearch, we subtracted debt, net of any cash of $49,000. Using a WACC of 45%, the resulting equity value is $329,000, or $0.15 per share. - -------------------------------------------------------------------------------- Howard, Lawson & Co. 5 Biosearch Medical Products, Inc. Opinion Letter - -------------------------------------------------------------------------------- Discussion (continued) Discounted Cash Flow (continued) In addition, we performed a DCF analysis in which Biosearch achieved approximately 55% of its forecast, as illustrated in Exhibit 8. Using the same discount rate of 45%, the resulting equity value is $445,000, or $0.20 per share. As indicated above, Biosearch has experienced declining revenues and continued operating losses during the last five fiscal years. However, the forecasts provided by Biosearch assume a turnaround in both revenue growth and profitability beginning in 1999. In addition, both DCF analyses illustrated in Exhibits 7 and 8 assume a turnaround of Biosearch. If it becomes apparent that Biosearch will be unable to meet its forecasts, then the appropriate steps will need to be taken to cut expenses in order to stem further losses and achieve the level of profitability indicated in the forecasts provided by Biosearch. On the basis of our discussions with management and the materials reviewed, it is our opinion that the fair market value for the Shares is $0.18 to $0.20 per share as of the Valuation Date. Acknowledgment This report was prepared by Frank Spewock and Michael Hanzelik, both employees of Howard, Lawson & Co. and actively involved in the firm's extensive valuation practice. The appraisers have no present or contemplated future interest in Biosearch or any other interest that might tend to prevent their making a fair and unbiased appraisal. This report has been prepared in conformity with the Uniform Standards of Professional Appraisal Practice of The Appraisal Foundation and the Principles of Appraisal Practice and Code of Ethics of the American Society of Appraisers. A signed certification is contained in the Methodology and Background exhibit of our report. Opinion On the basis of our analysis and the materials reviewed as stated in this letter, it is our opinion that Biosearch had a fair market value of $0.18 to $0.20 per share as of the Valuation Date. /s/ Howard, Lawson & Co.

Methodology & Background - -------------------------------------------------------------------------------- Overview Howard, Lawson & Co. provides investment banking services to the senior management of private and public companies. Services include financial plans for corporations and their shareholders, valuations of securities and business interests, fairness opinions, debt and equity financing, litigation support, advice and negotiations dealing with changes in ownership, acquisitions and divestitures. In forming our opinion as to the value of Biosearch as of the Valuation Date, we considered all the factors which we deemed relevant and have described them in our report. We have interviewed the senior managements of Hydromer and Biosearch, and reviewed those documents which were necessary to form a sound opinion as to the value of Biosearch. In forming our opinion, we have followed the suggestion of Internal Revenue Service Revenue Ruling 59-60, which states in part: "Because valuations cannot be made on the basis of a prescribed formula, there is no means whereby the various applicable factors in a particular case can be assigned mathematical weights in deriving the fair market value. For this reason, no useful purpose is served by taking an average of several factors (for example, book value, capitalized earnings and capitalized dividends) and basing the valuation on the result. Such a process excludes active consideration of other pertinent factors, and the end result cannot be supported by a realistic application of significant facts in the case except by mere chance." In forming our opinion, we have also reviewed relevant court cases, treatises and articles dealing with valuation procedures. - -------------------------------------------------------------------------------- Howard, Lawson & Co.
