Item 8. Fairness of Transaction.

     In  addition  to the  following,  see  Section  II of the Proxy  Statement,
subsections  entitled  "Special Factors - Intention of Certain Persons;  Special
Factors - Fairness Opinion; and Special Factors - Reports, Opinions,  Appraisals
and Certain Negotiations."

(a)  The issuer believes that this transaction is fair to unaffiliated  security
     holders.  Although  Manfred F. Dyck,  Director of the Issuer and  Hydromer,
     absented  himself from  discussions of the  transaction  and abstained from
     participating  in  the  negotiation  of  the  transaction,  because  of his
     security holdings in both Biosearch and Hydromer,  he has reviewed both the
     fairness opinion of Wharton Valuation  Associates provided to Biosearch and
     the reports of Howard Lawson & Co. provided to the Board of Hydromer,  (see
     Item 9 below) and the deliberations of the Biosearch Board and the Hydromer
     Acquisition   Committee  and  believes,   based  upon  these  reports,  and
     deliberations,  that  this  transaction  is fair to  unaffiliated  security
     holders of Biosearch. Martin C. Dyck has reviewed both the fairness opinion
     of Wharton  Valuation  Associates  provided to Biosearch and the reports of
     Howard Lawson & Co. provided to the Board of Hydromer,  (see Item 9 below),
     and the  deliberations of the Biosearch Board and the Hydromer  Acquisition
     Committee and believes,  based upon these reports and  deliberations,  that
     this transaction is fair to unaffiliated security holders of Biosearch. The
     Board of Directors of Hydromer  has reviewed  both the fairness  opinion of
     Wharton  Valuation  Associates  provided  to  Biosearch  and the reports of
     Howard Lawson & Co. provided to the Board of Hydromer,  (see Item 9 below),
     and believes,  based upon these reports,


<PAGE>

     that this transaction is fair to unaffiliated security holders.

(b)  The exchange  price  represents a premium over the current  market price of
     the Common Stock for most of the last two years and a  substantial  premium
     over the book value of the  Issuer.  The Board of  Directors  of the Issuer
     engaged a  valuation  expert  who  reviewed  the  transaction  and gave his
     opinion that the  transaction  was fair to the  shareholders of the Issuer.
     See Section II of the Proxy Statement,  subsections entitled "Book Value of
     the Company," "Share Price of Company," and "Price of Securities Before And
     After  Public  Announcement  on May 13,  1999,"  incorporated  by reference
     herein.

(c)  The transaction does not require the approval of a majority of unaffiliated
     security holders but can be passed by a simple majority of all shareholders
     who vote.

(d)  No such representative was retained,  but each filing person considers that
     the experts who have been retained by each company adequately protected the
     interests of the unaffiliated  shareholders,  and in fact such experts were
     retained for that purpose.

(e)  The transaction was unanimously approved by the directors of the Issuer who
     are not employees of the Issuer.

(f)  Not applicable.

Item 9. Reports, Opinions, Appraisals, and Certain Negotiations.

          as Exhibit RRBB ONE.

<PAGE>


     2.   See proposal letter of WVA and representative  transactions annexed as
          Exhibit 1 to this Statement.

     3.   WVA was recommended by Biosearch's  auditors and interviewed  directly
          by the Board of Directors of the Issuer.  Biosearch  considered  other
          advisors,  but concluded  that WVA was well  qualified and  reasonably
          priced.

     4.   WVA has no material relationship to the issuer or its affiliates,  and
          no  compensation  is to be received  by WVA except for its  engagement
          fee.

     5.   The amount of  consideration  was  negotiated  by the Issuer  with the
          advice of WVA.

     6.   WVA reviewed and summarized  the balance sheets and income  statements
          of Biosearch for the years 1993 through 1998 and the balance sheet and
          income statement at the end of the first quarter of 1999. WVA also did
          a discounted  cash flow analysis of Biosearch  using discount rates of
          35%,  30% and 25%.  WVA also  performed a  comparable  public  company
          analysis,  and an  analysis  of market  value  ratios  from  sales and
          mergers of medical instrumentation companies.  Lastly, WVA performed a
          liquidating  value analysis.  A valuation recap of all analyses showed
          the median share value to be $0.195 per share and the mean share value
          to be $0.216. No instructions were delivered to WVA from the Issuer or
          any Affiliate,  other than as set forth in the WVA's proposal  letter,
          and no limitations were placed upon WVA.

          opening  unit of the fair  market  value both  though,  the stock both
          Biosearch Howard Lawson considered the following factors:

               1. The nature and history of Biosearch business

               2.  To 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 any goodwill or other  intangible
               value

               7. Past transactions in Biosearch common stock and

               8. The market price of the stock of  corporations  engaged in the

          based upon  forecasts  of future  earnings,  adjusted  to reflect  the
          probability of a range of possible outcomes.

          On the basis of an asset  purchase,  and  excluding  all  liabilities,
          Howard Lawson was of the opinion that the relevant range of values for
          Biosearch was $0.16 to $0.18 per share.

          further assuming that Biosearch  achieves  approximately 41 percent of
          its forecast,  and using a discount rate of 45 percent,  Howard Lawson
          found the equity value to be $0.15 per share.  Assuming that Biosearch
          achieved  approximately  55  percent of its  forecast,  using the same
          discount rate of 45 percent,  Howard Lawson found the resulting equity
          value to be $0.20 per share.

          On the basis of their  discussions  with  management  at all materials
          reviewed,  it is the  opinion to Howard  Lawson  that the fair  market
          value  for  Biosearch  shares  is  $0.18-$0.20  per  share  as of  the
          valuation date. No instructions were delivered to Howard Lawson except

WHARTON PROPOSAL-   Proposal letter and  representative  transactions of Wharton
                    Valuation Associates.

November 6, 1998

Mr. Robert C. Keller
Vice President Finance
Biosearch Medical Products Inc.
35A Industrial Parkway
Somerville, NJ 08876

Dear Mr. Keller

Thanks  very much for taking the time to meet with  Andrew  Shaiman  and me last
week.  As requested,  I am outlining  the terms and  conditions by which Wharton
Valuation  Associates,  Inc.("WVA")  would be willing to render an opinion  with
respect to the financial fairness of a proposed merger between Biosearch Medical
Products Inc.  ("BMPI") and Hydromer  Inc.("HYDI").  Our opinion would  rendered
from a financial point of view from the perspective of BMPI's shareholders.

Biosearch Medical Products, Inc. ("BMPI")

BMPI was  incorporated  in the State of New Jersey on September  17,  1975.  The
Company's  early  emphasis was on contract  research and  development of medical
devices  and  systems  for larger  medical  product  companies.  During 1982 the
Company successfully made its initial public offering of equity securities.  The
Company had  designed  and  successfully  marketed  under its own  Dobbhoff  (R)
trademark,  a small bore  feeding  catheter  which  quickly  became the  enteral
industry's feeding device standard. Related products followed.

The dominance of the enteral food market by larger medical product companies and
reimbursement  changes in the Federal  Government  Medicare  System prompted the
Company's decision to reassess its business objectives. The Company subsequently
curtailed  its selling  activities  in the  alternate  care market and in August
1989,  laid  off its  dietary  sales  force.  During  1994,  BMPI  entered  into
agreements  with  Sherwood  Medical  Company  which formed with them a strategic
business  alliance.  In 1997  sales of  contracted  manufactured  products  were
approximately 80 percent of total sales.

BMPI's revenues have declined from  approximately $20 million in the late 1980's
to under $2 million in 1997,  while  operating  losses  have been  reduced  from
($842,004) in 1995 to ($493,367) in 1997 through  vigorous cost cutting efforts.
The Company's balance sheet showed a total  shareholders'  equity of $940,146 at
December 31, 1997. There are currently discussions underway with a large medical
products company which could well lead to sharply higher sales and earnings over
the near term.

Wharton Valuation Associates, Inc. ("WVA")

WVA is a  consulting  firm  engaged  primarily  in  the  valuation  of  business
interests and also in providing advice in connection with mergers, acquisitions,
divestitures  and similar  capital  transactions.  Although the firm has been in
existence for eight years, its managing  directors have a combined total of more
than 60 years of  experience  performing  valuations  and  acting  as  financial
advisers to corporations and their shareholders. Our valuations are performed in
connection with a variety of planning and transactional applications, including:
mergers,  acquisitions and divestitures;  initial public  securities  offerings;
private  placement of debt and equity;  employee  stock  ownership and incentive


<PAGE>


stock option plans; bankruptcies,  reorganizations and recapitalization; estate,
gift and income tax planning and compliance;  litigation  involving business and
securities  valuation issues;  and general  corporate and shareholder  planning.
Neither  WVA  nor  any  of its  employees  has  any  interests  in the  Proposed
Transaction which would compromise its ability to render an opinion with respect
to the Proposed Transaction in a totally objective and disinterested fashion. In
this  connection,  the fee for our services would in no way be contingent on the
value  or  on a  favorable  opinion  regarding  the  fairness  of  the  Proposed
Transaction.

Proposal

We would be willing to render an opinion with respect to the financial  fairness
to BMPI's shareholders of the Proposed  Transaction for a fee of between $25,000
and $30,000,  plus actual out-of-pocket data acquisitions  expenses (if any). As
noted above, the fee for this service would be contingent on our conclusion with
respect to financial fairness. Our opinion would be transmitted in the form of a
letter,  although we would make ourselves available to discuss with BMPI's Board
of Directors the basis for our conclusion.

We appreciate  very much being given the opportunity to propose on this project.
If you have questions regarding any aspect of the foregoing, please let me know.
If the terms of this Proposal are acceptable,  please sign this letter below and
return to my attention.
Sincerely,

Jeffery Nelson s/s
Managing Director
Wharton Valuation Associates, Inc.

PROXY STATEMENT

     This Proxy Statement, which will be mailed commencing on or about September
13, 1999 to the persons  entitled to receive the  accompanying  Notice of Annual
Meeting of  Stockholders,  is provided in connection  with the  solicitation  of
Proxies on behalf of the Board of Directors of Biosearch Medical Products,  Inc.
("Biosearch" or the "Company"), for use at the Annual Meeting of Stockholders to
be held on October 20, 1999, and at any adjournment or adjournments thereof, for
the purposes set forth in such Notice. The Company's executive office is located
at 35A Industrial Parkway, Somerville, New Jersey 08876.

     At the close of business on  September  1, 1999,  the record date stated in
the accompanying Notice, the Company had outstanding  2,202,878 shares of common
stock (a quorum  will be  1,101,440  shares),  without  par value  (the  "Common
Stock"), each of which is entitled to one vote with respect to each matter to be
voted on at the Meeting. The Company has no class or series of stock outstanding
other than the Common Stock.

     On  September  1,  1999,  Manfred  F. Dyck,  C.E.O.  and a director  of the
Company,  beneficially owned approximately 21.8% of the outstanding Common Stock
of the  Company  and  his  son,  Martin  C.  Dyck,  President  of  the  Company,
beneficially  owned an additional  1.8% of the Common Stock.  Such ownership may
enable such stockholders to exercise a controlling  influence over the Company's
affairs.

     Also on September 1, 1999  Manfred F. Dyck owned  approximately  47% of the
outstanding stock of Hydromer, Inc. Mr. Dyck is C.E.O., President and a Director
of Hydromer.  This common ownership  causes  Hydromer,  Inc. to be an affiliated
entity  pursuant to the Rules  promulgated  by the United  States  Security  and
Exchange Commission.

     IMPORTANT NOTES:

VOTING:

The vote required to elect directors or act on other proposals are a majority of
the votes  case,  for/against,  at a meeting  containing  a quorum.  A quorum is
attained if 50% plus one shares  (1,101,440) of the total outstanding shares are
represented at the annual meeting in person or by proxy. An abstention  (send in
proxy with no vote) counts  towards the quorum  requirement  but NOT towards the
vote to pass any proposals.  In the event a  stockholder,  holds their shares in
street name then broker is required to obtain instructions from each stockholder
on how to  vote  these  shares.  The  Company  and/or  its  contractor  solicits
information  from all known  brokers  holding  stock for the  benefit of others.
["street  name"  stock].  If the broker  does not vote the shares held in street
name the  effect is that the shares are not  counted  towards  the quorum or the
vote to pass any proposal.

FORWARD-LOOKING STATEMENTS:

     Certain  information  contained  in  this  Proxy  Statement  as  to  future
financial  or  operating  performance  of  Biosearch  or any  other  entity  may
constitute a "forward looking  statement".  Forward looking  statements  include
statements containing plans,  objectives,  goals,  strategies,  future events or
performance,  and underlying  assumptions and other  statements  which are other
then  statements  of  historical  facts.   Forward  looking  statements  can  be
identified by, among other things,  the use of forward looking  terminology such
as  "believes",  "expects",  "may",  "will",  "should",  "seeks",  "pro  forma",
"anticipates",  "intends",  "thinks"  or the  negative  of any of these terms or
similar terms having the same variation or are comparable to these terms,  or by
discussion  of strategy or  intentions.  Forward  looking  statements  involve a
number of risks  and  uncertainties.  A number of  factors  could  cause  actual
results, performance,  predictions or achievements of Biosearch, the industry or
any other entity to be materially different from any future results, performance
or achievements, expressed or implied, by such forward looking statements. These
factors include but are not limited to, the regulatory  climate such a reduction
in Medicare and Medicaid,  changes in the laws affecting the insurance industry,
HMO's,  PPO's  and  health  care  groups,  changes  in the  medical  device  and
industrial  products  for which  Biosearch  manufactures  products  or  performs
services,  changes  in  the  European  market  place  or  regulations  affecting
Biosearch's  ISO 9001  registration  and the CE Marks on certain of its products
and national economic conditions,  demographic trends, employee availability and
cost increases.

decline to serve.  Certain  information  concerning the nominees for election as
directors  is set forth below.  Such  information  was  furnished by them to the
Company.  In the event  Proposal  II is approved  by the  stockholders,  it will

Committee to oversee the auditing  process and evaluate the  performance  of the
outside accountants.  The Audit Committee met on one occasion in 1998. The Board

No other executive qualifies for inclusion in this table.

Notes:

     1. On October  29, 1997 Mr.  Dyck was  granted  77,617  options to purchase
     company  stock at $0.19.  This  grant  was  vested  in full.  (see  Options
     granted.)

     2. On May 5, 1998 Mr. Martin C. Dyck was appointed President of the Company
     (Mr.  Manfred Dyck  retaining  the  position of Chairman  and CEO).  Martin
     Dyck's 1998 Salary was less then $100,000.

     3. The other  annual  compensation  is  premiums  paid on a life  insurance
     policy for amounts over $50,000.

     4. Mr.  Dyck's salary for 1998 was $95,000.  The above table  reflects only
     what was actually paid. The remaining moneys plus additional accrued salary
     was paid in March of 1999.  (See  "Certain  Agreements  with  Directors and
     Executive Officers")

     The Company has customary  medical and group life insurance  programs.  See
"Certain Employee Benefit Arrangements" below. See also "Certain Agreements with
Directors and Executive Officers" and "Other Information  Concerning  Directors,
Officers,  and  Stockholders"  below.  The Company  makes  certain  benefits not
described  elsewhere herein  available to its executive  officers with a view to
acquiring and retaining  qualified  personnel and  facilitating job performance.
The Company considers such benefits to be ordinary and incidental business costs
and expenses. The aggregate value of such benefits in the case of each executive
officer in the above table, which cannot be precisely  ascertained,  but is less
than the lesser of (a) 10% of the total salary and bonus paid to each  executive
officer or (b) $50,000 as the case may be, is not included in such table.

Option Granted


     On October 29, 1997 Stock Options to purchase  200,041 shares at $0.19 were
awarded  to 13  managerial  and key  employees  including  Manfred  F.  Dyck who
received 77,617.  These options  immediately  vested.  The options expire if the
employee resigns. It was the Company's opinion that such awards are necessary to
retain the companies  experienced  key  employees  who have not received  salary
increments for the past three years.

important employees.

Long-Term Stock Incentive Plan Awards

     The Company did not have such a plan in effect for the fiscal year 1998 and
has no present intention to establish such a plan.

Profit Sharing Retirement Plan

     The Company has a "401K" Plan in effect for all of its  employees.  Subject
to the discretion of the Company, exercised each year, it contributes 33 1/3% of
employee  contributions up to 6% to the plan. Effective May 1, 1991, the Company
has discontinued  the  contribution  subject to further action by the Board. The
full costs of  administering  the plan,  which includes  service fees paid to an
insurance  company for  administering  the plan and monies paid to the Company's
auditors to provide an audit report, will be borne by the Company.

Certain Agreements with Directors
and Executive Officers

     Mr. Dyck has an  employment  agreement  with the Company  which  provides a
minimum annual salary of $192,500, and a 6-month notice of termination. Mr. Dyck
was required to devote at least 90% of his  business  time to the affairs of the
Company.  On January 1, 1993 the  Company  and Mr.  Dyck  agreed that his annual
salary  would be reduced to $96,500  and he would be  required to work on a part
time  basis of three  days per  week.  On June 4,  1994 Mr.  Dyck's  salary  was
increased  to the full time amount (90% of his time) of  $193,000  per year.  In
December 1994 as part of a cost reduction plan, Mr. Dyck voluntarily agreed to a
salary  reduction to $150,000 per year.  On February 5, 1997 Mr. Dyck  presented
the Board with a cost  reduction  program  which  resulted  in his salary  being
voluntarily reduced to $95,000/year based on a three day work week. On 5/5/98 by
consent and  agreement,  Mr.  Dyck's  salary was amended to $95,000  accrued not
paid. He agreed to be removed as  President,  but retained the title of Chairman
and CEO. Mr. Martin C. Dyck, son of Mr. Dyck was appointed President.

     In June of 1998 the Board passed a resolution  providing  that in the event
of change of control to one  entity or more than one entity  acting in  concert,
key employees are to be  immediately  paid a percentage of their yearly  salary.
Mr.  Martin C. Dyck,  President is to be paid one years salary and Mr.  Keller a
Vice President and the treasurer is to be paid 25% of a years salary. Four other
key employees  are to be paid 25% of their salary.  The total payment if made on
12/31/98 would have been $136,000. On May 12, 1999 at a special board meeting to
consider  the offer made by  Hydromer,  Inc. to  exchange  $0.20 for each common
share of the Company,  Mr. Martin C. Dyck waived this change of control  payment
($72,000) in lieu of an offer by Hydromer of the position of Vice President at a
salary of $110,000 per year and an option to purchase  10,000 Hydromer shares at
a price equal to the last five day average market price on the day of closing of
the exchange transaction (see Proposal II.)

     On  December  30,  1998  the  Company  paid  Mr.  Martin  C.  Dyck $  8,492
representing  salary  earned but not paid and on March 4, 1999 the Company  paid
the Directors as a group $ 70,500  representing  directors'  fees earned but not
previously  paid.  On March 11,  1999 the amount of  $76,730  owed to Manfred F.
Dyck,  C.E.O. for salary


                                      -5-
<PAGE>


accrued  was paid.  On March 17,  1999 the Board  agreed to  continue  to accrue
directors'  fees,  and  Manfred  F. Dyck  agreed to a  continued  accrual of his
salary.  On July 21, 1999 the Directors  voted to pay all Directors fees owed to
date and continuing  paying  director's  fees as they become due. Mr. Manfred F.
Dyck agreed to allow the Company to continue accruing his salary.

     For services  rendered to the Company certain directors of the Company were
granted options to purchase Common Stock of the Company.  (See "Options Granted"
above.)

     Each  director of the Company is  entitled to receive  compensation  in the
amount of $750 for each  meeting of the Board of  Directors  attended  either in
person  or  telephonically,  and  $200  for  each  specially  called  telephonic
conference  meeting.  In March of 1999 and until further notice the Board agreed
to accrue, but not pay Directors fees.

Other Information Concerning Directors,
Officers and Stockholders


     The Company, during 1998 was a party to various transactions with Hydromer,
Inc., an affiliated  entity.  Hydromer  provides the Company with  chemicals and
analytical services.  In 1998 the Company purchased  approximately $35,000 worth
of goods and  services  from  Hydromer  and billed  Hydromer  for  approximately
$26,000  for  services  and out of pocket  expenses  incurred in its behalf (the
Company  provides  secretarial  services to  Hydromer  at $500 per  month).  The
Company  has  served as the a  subcontractor  of  Hydromer  to  provide  coating
services on various  products  using the chemicals made by Hydromer at prices it
would charge to any other  non-affiliated  party for like services.  The Company
paid  $38,900 to  Hydromer as  royalties  owed up to the date of  expiration  or
termination on patents that expired or were terminated in March of 1998.

     In 1997 the Company was a party to various transactions with Hydromer, Inc.
Hydromer  provides the Company with chemicals and analytical  services.  In 1997
the Company  purchased  approximately  $40,000  worth of goods and services from
Hydromer and billed  Hydromer for  approximately  $77,000 for  services,  out of
pocket  expenses  incurred  in its  behalf  (the  Company  provides  secretarial
services  to  Hydromer  at $500 per  month),  the  purchase of a curing oven for
$46,000 and rented some space at Biosearch  for $19,000.  This  arrangement  for
space was terminated in latter 1997 and the oven was removed and  reinstalled at
Hydromer's production facility. The Company paid Hydromer $29,000 representing a
minimum  royalty  fee for a  patent/know-how  license  concerning  the  Hydromer
coatings and accrued an  additional  $26,875 for  royalties due but not paid. In
late 1997 Hydromer and Biosearch  entered into a secrecy  agreement  whereby the
Officers of Hydromer were granted access to the non-public  records of Biosearch
to explore any possible  business  relationships or ventures.  On March 31, 1998
the Company and  Hydromer  entered  into a contract  of sale  whereby,  Hydromer
agreed to purchase the Company's  building and land at a price of $850,000 and a
three year  lease-back to the Company of 16,000  square feet (approx.  2/3rds of
the building). The parties valued the lease at $346,500.  Closing is expected to
take place with 60 days.

     From July 96 to June 98  Hydromer  purchased  an  aggregate  of  $46,500 of
furniture from Biosearch at terms Biosearch is of the opinion was fair and on no
less favorable terms available to a non-affiliated party.

     In late 1997  Hydromer  and  Biosearch  entered  into a  secrecy  agreement
whereby the Officers of Hydromer were granted access to the  non-public  records
of Biosearch to explore any possible business relationships or ventures.

     On March 31, 1998 the Company and Hydromer  entered into a contract of sale
whereby,  Hydromer agreed to purchase the Company's building and land at a price
of $850,000  and a three year  lease-back  to the Company of 16,000  square feet
(approx. 2/3rds of the building). The parties valued the lease at $346,500. The
transaction  was closed on June 12,  1998.  Since then the  parties  have shared
various  costs in  accordance  with the terms of the lease in the area of taxes,
utilities,  security,  cleaning,  and other  services  which are in common.  The
Company  believes  that the  terms  of the  foregoing  arrangement  are fair and
equitable  to both  parties  as prior to the  closing,  a  non-affiliated  party
canceled a  transaction  of  substantially  the same terms  (except the purchase
price was $50,000 higher then purchased by Hydromer),  due to their inability to
obtain  a  mortgage.  After  this  cancellation  and  prior to the  purchase  by
Hydromer,  Inc.,  Summit Bank, the holder of a $840,000 mortgage filed an action
seeking  foreclosure  against Biosearch and a court order to conduct a sheriff's
sale of Biosearch's  property.  If not for the sale to Hydromer,  Inc. it is the
opinion of Biosearch  that the sale price of the property at a forced sale would
have been substantially  less that the amount paid by Hydromer,  Inc. There were
no other potential buyers.

     As of April 20, 1998, as part of a cost reduction plan, the General Counsel
was  employed  by the  Company  on a part  time  basis  of 1 day per  week.  The
remaining 4 days are spent as the General Counsel of Hydromer. In the event of a
conflict between the Company and Hydromer, outside counsel is used.


                                      -7-

     In August of 1998, the Hydromer Board of Directors  considered  that it may
be  beneficial to Hydromer to acquire the stock of Biosearch  Medical  Products,
Inc.  Hydromer is a company  which is an affiliate of Biosearch by virtue of the
common stock  ownership  and control of both  companies by Manfred F. Dyck.  The
Hydromer  Board  considered  that  Hydromer  could  make  use of Food  and  Drug
Administration-  registered  manufacturing  facilities of Biosearch for coating,
and prototype development under GMP/ISO 9000 conditions, which the company needs
to  remain  competitive.  The  Hydromer  board  also  considered  that  a  stock
acquisition  would permit the possible use of tax loss carry forwards  ("NOL's")
which could improve  Hydromer's cash flow.  Because of the potential conflict of
interest,  Manfred  F. Dyck and  Ursula M. Dyck  excused  themselves  from these
deliberations and the Board  established its three independent  directors Robert
Bea, Dieter Heinemann and Dr. Maxwell Borow, to act as an Acquisition  Committee
with authority to evaluate and recommend a course of action for Hydromer in this
matter.

     The  Hydromer's  Acquisition  Committee  considered  external  reports from
Howard Lawson & Co. and a report from Hydromer's independent accountants.

     In  September of 1998,  Hydromer  qualified  its interest in acquiring  the
stock of the Company in a stock  exchange at the ratio of 6 shares of  Biosearch
stock for each one share of Hydromer and  conditioned on certain  liabilities of
Biosearch being eliminated.  The Board of Directors (Manfred F. Dyck, not taking
part in the  decision)  was of the opinion that the stated terms might not be in
the best interests of the  stockholders  as the assets of the Company were worth
more then the total value of the Hydromer shares that the Biosearch stockholders
would have  gotten.  In September  of 1998  Hydromer  shares were selling on the
"pink sheets" (OTC Bulletin Board) at prices fluctuating  between $0.62 to $0.95
(with  occasional  spikes over $1.00);  Biosearch  shares were selling at prices
ranging from $0.06 to $0.14.  At this time  Biosearch was  negotiating  an asset
sale and a technology license with C.R. Bard, Inc. and was unsure of the outcome
in respect to the value of the Company.  The Biosearch Board was optimistic that
such a transaction  could  increase the perceived  value of Biosearch to a third
party.  With respect to the price of the Company's  stock,  it is the opinion of
Biosearch  that the OTC  Bulletin  Board does not  reflect the true value of the
Company's stock due to small amount of transactions  and the wide fluctuation in
price that can occur because of a few small transactions.

     In March of 1999 the Biosearch directors sought the advice of an evaluation
expert  to render a  fairness  opinion.  (See  Exhibits  B and B1 of this  Proxy
Statement for a sumary of the report rendered by Wharton  Valuation  Associates,
Inc.)

     In April 1999, Hydromer expressed interest to exchange each Biosearch share
for a payment  of $0.15.  In  addition  there were  other  conditions  which the
Biosearch  board found to be burdensome on certain  employees (it required 5 key
employees to waive a total of $136,000 in  compensation,  due and payable upon a
change  of  control.  This  conditional  compensation  was given  because  these
employees  have not gotten raises in the past few years.) The Directors  were of
the  opinion  that  loss of these  key  employees  would be  detrimental  to the
operation of Biosearch.

     On May 10, 1999 Hydromer, Inc. revised its offer to $0.20 and the allowance
of part of the employee  change of control  payment and at a special  meeting of
the  Biosearch  Board of  Directors,  held on May 12, 1999 the  Biosearch  Board
approved the offer and directed that it be presented to the  stockholders  for a
vote. A PLAN OF EXCHANGE was  thereafter  approved at the regular  Board meeting
held on May 27, 1999 (see Proposal II).

     In the latter part of 1998 the Company and Hydromer formed a Y2K joint task
force to assess the effect the Y2K problem would have on the facilities, jointly
occupied.  The  companies  are  devising  a  plan  that  in the  opinion  of the
management  of the Company will be less  expensive  to  implement  then any plan
implemented alone by the Company.

     On February 25, 1999 the Company closed a transaction  with C.R. Bard, Inc.
which transferred the Company's process coating technology and a coating machine
pertaining to  intermittent  urinary  catheters for the sum of $650,000.  On the
same  date,  Hydromer  closed a  transaction  which  licensed  the  right to use
Hydromer's  coating  chemicals  on the same device.  Biosearch's  contract had a
condition  whereby,  the closing was  conditioned  on the  Hydromer  transaction
closing at the same time. Outside counsel was used to represent the interests of
Hydromer, because of a potential conflict.

     On June 28, 1999 the C.F.O.  of Biosearch  (Mr.  Robert  Keller)  agreed to
provide accounting services to Hydromer, Inc. on a part time basis in such a way
as it would not interfere  with his  responsibilities  at  Biosearch.  The total
amount of his compensation for 1999 is expected to be far less then $100,000.

     Manfred F. Dyck, C.E.O. of the Company and his wife Ursula M. Dyck are also
directors of Hydromer. Mr. Manfred Dyck is the President and CEO of Hydromer. In
total they hold 42% (on a fully diluted basis) of the


                                      -8-

capital  stock of  Hydromer.  Their son Martin C. Dyck,  who is President of the
Company, owns 46,152 shares or 1.1% of Hydromer stock.

                          II. SHARE EXCHANGE for $0.20
                                  (Proposal II)

SHOULD THE  SHAREHOLDERS  OF THE COMPANY  EXCHANGE (a form of sale) THEIR SHARES
FOR A PAYMENT OF $0.20 PER SHARE.  Upon the  affirmation  vote of a majority  of
votes cast at the meeting, all issued and outstanding shares of the Company will
be exchanged for $0.20 per share.

[The BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE YES TO THIS PROPOSAL II.]

Information about transaction:

     If approved by a majority  of the votes cast at a quorum  representing  50%
plus 1 of the  outstanding  shares  and  pursuant  to New  Jersey  Law  N.J.S.A.
14A:10-13 (Share Exchange) all the issued and outstanding shares of Common Stock
of the Company will be acquired by Hydromer,  Inc. a New Jersey Corporation as a
wholly owned,  non-public subsidiary by exchanging each share of the Company for
the right to  receive a payment  of $0.20  ("Share  Consideration").  Hydromer's
principal  place of business is 35  Industrial  Parkway,  Branchburg,  NJ 08876,
(908-  526-2828).  Hydromer is an  affiliate of the Company  because  Manfred F.
Dyck, CEO of both company's owns a substantial amount of stock in both companies
to exercise a controlling influence over the affairs of both companies.

     If a majority of the votes cast by holders of shares  which are entitled to
vote on the plan of exchange  approve  this plan then on the  effective  date of
exchange  the share  certificates  shall only  evidence the right to receive the
Share  Consideration  times the amount of the shares on the certificate  (orange
certificate).  In the  event a share  certificate  is blue in  color  the  Share
Consideration shall be divided by 5 (in 1996 there was a 1 for 5 reverse split),
as the blue certificates represents pre-split shares

Right of dissent/appraisal:

     Under the New Jersey Business Corporation Act, because the consideration is
cash,  shareholders  have no statutory  right of dissent or appraisal  [N.J.S.A.
14A:11-1(a)(i)(B)]

     The New  Jersey  Business  Corporation  Act  (the  "Act")  sets  forth  the
procedure for and authorizes the share exchange proposed herein.  However,  even
full  compliance  with the provisions of the Act does relieve the directors of a
corporation from their fiduciary obligations to all shareholders, and New Jersey
case law permits a shareholder  to bring an action to enjoin a transaction  such
as the one  proposed  herein if the  transaction  does not  conform to  accepted
concepts of fairness  and  equity.  The Boards of  Directors  of  Biosearch  and
Hydromer,  for the reasons set forth in this Proxy Statement,  believe that this
transaction conforms to such concepts.

Shareholders Protection Act:

     In New  Jersey  there  is a law  known  as  the  "New  Jersey  Shareholders
Protection Act" [N.J.S.A.  14A:10A-1 et seq. the "Protection  Act"].  One of its
purposes as stated is to discourage  takeovers of public  corporations  financed
largely  through  debt to be repaid  in  short-term  by the sale of  substantial
assets of the target  corporation.  These takeovers  prevent  shareholders  from
realizing the full value of their  holdings  through forced mergers and coercive
devices.

     The   Protection  Act  prevents  any  business   combinations   between  an
"interested  shareholder" as defined in the law, and the Company for a period of
five years unless the business combination is approved by the Board of Directors
prior to the  interested  stockholder's  stock  acquisition  date or unless  the
transaction  is  otherwise  exempt  from  the  law.  There  are two  "interested
shareholders" in this transaction.  Hydromer, Inc. which will acquire the shares
of the  Company  and Mr.  Manfred  F. Dyck who holds more then 10% of the voting
shares of both Hydromer and the Company.  The business  combination in this case
occurs when the Company  becomes a wholly owned  subsidiary  of  Hydromer,  Inc.
Prior to the  shareholders  vote on this  matter,  the  Board of  Directors  has
investigated  the  fairness  of  the  share  exchange,   hired  and  independent
evaluation  expert.  This expert was of the opinion  that the  exchange  rate of
$0.20  per share is fair.  (See  Fairness  Opinion,  Exhibit  B).  The Board has
approved  the   transaction   and  has  submitted  the  final  approval  to  the
shareholders.

     Hydromer's  acquisition  of  the  Company's  shares  is  permitted  by  the
Protection  Act  because the  Company's  Board of  Directors  has  approved  the
transaction  before  Hydromer has acquired any shares of the Company.

[N.J.S.A. 14A:10A-4 and 5a.]

     Although  Manfred F. Dyck is an "interested  shareholder"  by virtue of his
share ownership of Hydromer, Inc. [N.J.S.A. 14A:10A-3j(2)],  this transaction is
specifically  exempt  from the  Protection  Act  because  Manfred F. Dyck owns a
smaller  proportion of the voting power of the Company on the Effective  Date of
this transaction (21.8%) then he owned on the effective date (August 5, 1986) of
the Protection Act (41.2%) [N.J.S.A. 14A:10A-6b]

Reasons for this transaction:

     The Company has been struggling to increase sales by using direct mailings,
     Internet  solicitations,  phone solicitations and attending trade shows. In
     1999 it has  entered  into OEM  agreements  with  Wilson-Cook  and  Applied
     Medical  Resources.  However the lack of any capital for marketing programs
     has impeded the Company's ability to exist as a going concern.  It has been
     unable to obtain financing due to its financial history and to maintain its
     existing  operations  the  Company  has had to sell off some of its  assets
     (sold  its  real  property  in 1998 to  terminate  foreclosure  proceeding,
     executed  a stand  still  agreement  in 1998  for  $200,000,  sold  urinary
     catheter coating business in 1999 for $450,000). Some attempts at financing
     include:  internet solicitations for debt financing (no response);  private
     offerings through investment bankers and financial intermediaries (fees too
     high and results too speculative); direct private placements (price was far
     less the $0.20).

     The Company has rejected filing under the Bankruptcy  statutes as it was of
     the  opinion  that one  asset  which  would be lost was its "Net  Operating
     Losses". The NOL can be used to lower taxes under certain conditions. It is
     the  Company's  opinion  after  seeking  advice from its  experts  that the
     liquidation  value of  Biosearch  would be less then $0.15 per  share.  See
     summary  of the  Wharton  Presentation  to the Board of the  Company  which
     follows  Exhibit B (see also "Forward  Looking  Statements"in  the front of
     this proxy).

     Hydromer has the marketing and sales  organization  that would increase the
     sales volume of activities  within the Company's area of expertise which is
     the  manufacture  and  coating of medical  devices.  The Company has an FDA
     registered  facility  which also is  registered  under ISO 9001 (A standard
     used in Europe).  The Company is authorized to put the "CE Mark" on some of
     its  medical  products  such as stents,  biofeedback  devices  and  various
     catheters.

     As to  Hydromer,  Inc. it sees  benefits in the  Company's  operation.  The
     Company has used  Hydromer's  chemicals on most of its medical  devices and
     has developed  expertise in the use of  Hydromer's  Coatings in medical and
     commercial applications. At present, Hydromer does not have any engineering
     or  production  facilities to develop  prototype  uses for its coatings and
     other chemicals;  in addition it cannot provide coating services on medical
     devices as it is not registered as a medical device manufacturer. Biosearch
     will bring such  abilities and the  production  facilities to do production
     runs. Hydromer will, in addition be able to make use of the tax credits the
     Company  has  built up due to  losses  (Net  Operating  Losses  or  NOL's).
     Hydromer  values these NOL's at a maximum of $12,000 if Hydromer  continues
     to be profitable.  There is, of course, no assurance that the Net Operating
     Losses will be useful  unless they can be offset  against  income tax owed.
     The change of control limits the use of NOL's to approximately  $12,000. If
     the transaction was not done and Biosearch would be profitable the value of
     the NOL's could be as high as $250,000.  Use of NOL's is highly speculative
     and there is no assurance that Biosearch  could ever use them. It is likely
     that these NOL will be used to some extent by Hydromer.

     Biosearch is of the opinion  that the  structure  of this  transaction  was
     chosen by Hydromer to be easy for the  stockholders  to  comprehend  and to
     maintain the corporate  existence of Biosearch to take advantage of the FDA
     and ISO  9000  registrations  as well as the Net  Operating  Losses  in the
     future.  The  structure  was  independently  chosen by Hydromer  during the
     negotiation  between  the outside  Board  members of both  Companies.  (Mr.
     Manfred F. Dyck did not take part in the discussions).  The Biosearch Board
     exercising it business  judgement  originally felt the transaction could be
     consummated  in a  shorter  time  frame  then  a  share  exchange.  If  the
     transaction  required the exchange of Biosearch  stock for Hydromer  stock,
     the time and expense of  complying  with the  registration  procedures  for
     Hydromer stock would have resulted in undesirable delay and expense.

     In the opinion of the Company its shareholders will be given a premium over
     the past market price. The transaction is structured pursuant to New Jersey
     Law, whereby  majority vote is conclusive.  Neither the market or any third
     party has come forward to date and offered a better price/terms.  Biosearch
     has never paid any  dividends  either  because of its past loses or because
     past financing  covenants  precluded  payment.  It is the Company's opinion
     that there are no real  detriments  for the  Biosearch  stockholder.  Other
     structures of transactions  (like a share for share exchange) were rejected
     because of the  transaction  costs and the time  factors.  (Hydromer  stock
     would  have to be  registered.)  The  transaction  form was  chosen  as the
     simplest way to obtain a fair amount for the Company's  stock. If Biosearch
     stockholders desire to retain any equity in the combined Hydromer-Biosearch
     entity,  they can easily purchase  Hydromer stock on the public market (OTC
     "pink sheets").

     Hydromer's  Acquisition Committee considered an acquisition of Biosearch on
     a liquidation  basis, and net book value basis, but considered also that an
     acquisition  of assets on those bases would not bring to  Hydromer:  1. the
     Food and Drug Administration  registration for a manufacturing  facilities,
     2. the ISO 9000  approval  or 3. the tax loss carry  forwards,  which would
     remain with the corporate shell.

                                      -11-
<PAGE>


     Acquisition without these benefits was determined not to be in the interest
     of Hydromer  and since the  acquisition  of the  Biosearch  stock was for a
     price that is greater  then the price that  Biosearch's  stock is  publicly
     traded  (ignoring  unjustified  peaks from time to time) Hydromer is of the
     opinion that the $0.20 per share price is fair. For these  reasons,  Martin
     C. Dyck also  determined  that  Biosearch  was most valuable if the company
     were  acquired  in an  exchange  of stock  for cash,  rather  than an asset
     transaction.  Martin C. Dyck considers  this  transaction to be fair to the
     non-affiliated  stockholders because in his opinion the future of Biosearch
     as a going  concern  is not  certain.  As a  condition  of the  transaction
     closing  Mr.  Martin C. Dyck has waived  the  change of control  payment of
     $72,000  due him at the  closing.  He will be  offered a  position  of Vice
     President of  Manufacturing at Hydromer for an anual salary of $110,000 and
     10,000  stock  options  at a price  set by the 5 day  average  prior to the
     closing.

     Although  Manfred F. Dyck did not  participate  in the  negotiation  of the
     terms and conditions of this transaction, he concurs that the result of the
     transaction  after  reading  the  (reports  and  minutes  of  the  Hydromer
     Acquisition  Committee  and the  Biosearch  Board  minutes,  that  were not
     available  to him during  the  negotiation)  is fair to the  non-affiliated
     stockholders.

Intentions of certain persons:

     Mr. Manfred F. Dyck,  C.E.O.  of both companies will exchange his shares at
     the same price as all other  stockholders  of the Company ($0.20 per share)
     (see "Information Concerning Certain Stockholders"). He intends to vote YES
     on this Proposal II. He has not made any statements for or in opposition to
     this Proposal II and has abstained as a Director from any  consideration or
     vote on this matter. However as a member of the Board of Directors, they as
     a group have recommended  that the  stockholders  vote YES to this proposal
     II.

     Although  Manfred F. Dyck,  Director of the Issuer and  Hydromer,  absented
     himself  from   discussions   of  the   transaction   and  abstained   from
     participating  in  the  negotiation  of  the  transaction,  because  of his
     security  holdings in both  Biosearch  and  Hydromer,  he has  reviewed the
     fairness opinion of Wharton Valuation Associates provided to Biosearch, and
     the  deliberations  of the  Biosearch  Board and the  Hydromer  Acquisition
     Committee and believes,  based upon these items,  that this  transaction is
     fair to unaffiliated security holders. Martin C. Dyck has reviewed both the
     fairness opinion of Wharton Valuation Associates provided to Biosearch, and
     the  deliberations  of the  Biosearch  Board and the  Hydromer  Acquisition
     Committee and believes,  based upon these reports, that this transaction is
     fair to unaffiliated  security holders.  The Board of Directors of Hydromer
     has reviewed the fairness opinion of Wharton Valuation  Associates provided
     to  Biosearch,   and   believes,   based  upon  this  review  and  its  own
     deliberations and the outside reports of its experts, that this transaction
     is fair to  unaffiliated  security  holders.  Manfred F. Dyck and Martin C.
     Dyck intend to vote "YES" for Proposal II. Hydromer does not own any shares
     of Biosearch,  and cannot vote on the proposal. No information is available
     to any filing person as to the intentions or mental impressions of officers
     and  directors  of Biosearch  and  Hydromer  with respect to voting on this
     transaction.

Reports, Appraisals and Certain Negotiations

          by the Board of Directors of the Issuer.  Biosearch  considered  other
          advisors,  but concluded  that WVA was well  qualified and  reasonably
          priced.

     4.   WVA has no material relationship to the issuer or its affiliates,  and
          no  compensation  is to be received  by WVA except for its  engagement
          fee.

     5.   The amount of  consideration  was  negotiated  by the Issuer  with the
          advice of WVA.

     6.   WVA reviewed and summarized  the balance sheets and income  statements
          of Biosearch for the years 1993 through 1998 and the balance sheet and
          income statement at the end of the first quarter of 1999. WVA also did
          a discounted  cash flow analysis of Biosearch  using discount rates of
          35%,  30% and 25%.  WVA also  performed a  comparable  public  company
          analysis,  and an  analysis  of market  value  ratios  from  sales and
          mergers of medical instrumentation companies.  Lastly, WVA performed a
          liquidating  value analysis.  A valuation recap of all analyses showed
          the median share value to be $0.195 per share and the mean share value
          to be $0.216. No instructions were delivered to WVA from the Issuer or
          any Affiliate,  other than as set forth in the WVA's proposal  letter,
          and no limitations were placed upon WVA.

          the stock  both  Biosearch  Howard  Lawson  considered  the  following
          factors:

          1.   The nature and history of Biosearch business

          2.   To 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 any  goodwill or other  intangible
               value

          7.   Past transactions in Biosearch common stock and

          8.   The market price of the stock of corporations engaged in the same

     estimated  fair market values of Biosearch's  fixed and intangible  assets.
     Howard Lawson also  performed a discounted  cash flow  analysis  based upon
     forecasts  of future  earnings,  adjusted to reflect the  probability  of a
     range of possible outcomes.

     On the basis of an asset purchase,  and excluding all  liabilities,  Howard
     Lawson was of the opinion that the relevant  range of values for  Biosearch
     was $0.16 to $0.18 per share.

     Assuming that Biosearch can turn around its declining  revenues and further
     assuming that Biosearch achieves  approximately 41 percent of its forecast,
     and using a discount  rate of 45 percent,  Howard  Lawson  found the equity
     value to be $0.15 per share. Assuming that Biosearch achieved approximately
     55 percent of its  forecast,  using the same  discount  rate of 45 percent,
     Howard Lawson found the resulting equity value to be $0.20 per share.


     On the  basis  of  their  discussions  with  management  at  all  materials
     reviewed, it is the opinion to Howard Lawson that the fair market value for
     Biosearch  shares is  $0.18-$0.20  per share as of the  valuation  date. No
     instructions  were  delivered  to  Howard  Lawson  except to  describe  the
     valuation  services  needed,  and no  limitations  were  placed upon Howard

Business of Hydromer, Inc.:

     Hydromer,  Inc. is a  corporation  organized in April of 1980. In September
1982 it was spun off  from the  Company  to  exploit  certain  chemical  coating
technology (chemicals that become dry on a surface but become slippery when wet)
invented by the Company in the industrial/medical device market place. Presently
Hydromer  occupies 33% of the building  that the Company  leases from  Hydromer.
Hydromer manufactures chemicals and performs R&D in the polymer coating markets.
Hydromer's annual sales for the year ending 6/30/98 were $2,360,570.

     Hydromer intends to use the Company's  currently under utilized  facilities
to produce items that would  otherwise have to be  subcontracted.  Hydromer also
believes  that the Company's  medical  coating  expertise  will be a synergistic
addition to its own capabilities.

     Hydromer and Biosearch are related parties  (affiliated  entities)  because
Manfred F. Dyck holds a substantial amount of stock in both companies. A summary
of the  relationships  with the  numbers  computed  on the basis of  Biosearch's
fiscal  year  can be found  under  Proposal  I,  "Other  Information  Concerning
Directors, Officers and Stockholders"

     Hydromer  manufactures  chemicals  that  are used as  lubricous  (slippery)
coatings on medical products and on industrial surfaces for anti-fog properties.
Hydromer also  manufacturers  chemicals that form gels intended for medical uses
and cosmetic  components.  Biosearch is a medical device  manufacturer which has
developed  expertise in the process of applying  coating to various  substrates.
Hydromer does not have the  experience in applying its own coatings  outside the
laboratory  environment.  In  Hydromer's  opinion the  acquisition  of Biosearch
brings  with  it  this  commercial  technology  which  will  allow  Hydromer  to
immediately  expand the market for its patented  products  and related  services
using these  products to customers  in the medical  device  marketplace  because
Biosearch is registered with the FDA and has an ISO 9000 registration.

Summary of material features of this Exchange:

     a. The Board of Directors have proposed that each  stockholder vote for the
     exchange (sale) of each of their common shares of the Company for a payment
     of $0.20.  Once  approved by a majority  of the votes cast at the  meeting,
     Biosearch  stock  certificates  will be evidence to receive $0.20 times the
     number of shares held.

     b. Both Hydromer and Biosearch  represent to each other that they are valid
     companies  and they  can  enter  into  this  exchange  if  approved  by the
     Biosearch shareholders.

     c. Either  company can  terminate  the exchange if in the opinion of either
     Board of Directors there is a material change in the business of the other.
     One specific  requirements is that Biosearch's current debt, excluding debt
     to Hydromer cannot exceed $100,000.  In the opinion of Biosearch,  it feels
     this  condition  can be achieved if there is no further  material  delay in
     closing this transaction.

     d. In  addition,  the  President  of the  Company,  Martin C. Dyck has been
     offered  employment with Hydromer,  Inc. as the Vice President of Operation
     at a salary of $110,000 per year. He will also be given options to purchase
     10,000 shares of Hydromer,  Inc. at the 5 day rolling  average market price
     prior to the Effective Date. Mr. Martin C. Dyck will remain as President of
     Biosearch   Medical   Products,   Inc.  at  a  salary  of  $1.00/year.   In
     consideration,  Mr.  Martin C. Dyck  agreed to waive a "change of  control"
     payment  of  $72,000  which was


                                      -15-
<PAGE>


     awarded  in June of 1998.  Four  other key  employees  were also  awarded a
     "change of control payment", which Hydromer, Inc. has agreed to allow to be
     paid ($64,000)

     e. From time to time the Company has issued  options (there are no warrants
     outstanding)  to its key employees.  Hydromer will pay these  employees the
     difference  between  .20 and the option  price if under .20 time the shares
     represented  by the  option  certificate.  Mr.  Manfred  F. Dyck  holds the
     greatest amount of option for which he will receive $776. To the extent the
     option price is higher then $.20 they will be allowed to expire.

     f.  Manfred F. Dyck holds  480,004  shares of the Common Stock of Biosearch
     and will be paid a total of $96,000.80 in exchange for his shares. Martin C
     Dyck holds an aggregate of 39,041  shares of Common Stock of Biosearch  and
     will be paid an aggregate  of  $7,808.20  in exchange for his shares.  Both
     Manfred F. Dyck's and Martin C.  Dyck's  interest in the net book value and
     net earnings of Biosearch will be  proportional to their  respective  share
     holdings  in  Hydromer.  Manfred  F. Dyck  holds  approximately  47% of the
     outstanding  shares of  Hydromer,  and  Martin C. Dyck  holds less than one
     percent of the  outstanding  shares of  Hydromer.  As  Biosearch  will be a
     wholly-owned subsidiary of Hydromer,  Hydromer will have a 100% interest in
     the net book value and net earnings of Biosearch.

     g. It is anticipated that the duration  between the  stockholders  approval
     and the  closing  of the  exchange  (upon  filing in the N.J.  Division  of
     Commercial  Recording per New Jersey Law), will be less then two weeks). It
     is  further  anticipated  that  notices  to  shareholders  to send in their
     certificates  will be done within 4 weeks.  Shareholders will send in their
     certificates  and  a  form  requiring  their  social  security  number  and
     certification in the absence of backup withholding.  Payment in the form of
     a check will be sent as soon as possible.

Accounting Treatment:

     The proposed transaction is a business combination  accounted for under the
purchase  method,  effective  on the  date  of the  transaction.  Balance  sheet
elements of both  companies  will be combined on the effective  date. The monies
paid to the  stockholders  for their exchange of Biosearch  stock along with the
fees  and  costs  associated  with  the  acquisition  will be  accounted  for on
Hydromer's  balance sheet as an investment  in a  subsidiary.  The  consolidated
stockholders  equity  that  remains on the  effective  date will go to  Hydromer
(Biosearch's stockholders' equity will be eliminated upon consolidation). Assets
of Biosearch Medical Products, Inc. will be appraised and recorded at their fair
value on the consolidated  balance sheet. Any difference between the amount paid
to Biosearch  stockholders  (the Purchase Price) and the fair value of Biosearch
will result in good will.  This goodwill will be amortized  over 20 years.  This
amortization is not deductible for tax purposes.

     Fixed  assets will be recorded at fair value as of the close of business on
the effective date. Any balances between  Hydromer and Biosearch,  such as trade
payables and  receivables,  prepaid and deferred  rent,  will be  eliminated  in
consolidation.

Federal Income Tax Consequences:

     The exchange (form of sale) of Common Shares into the right to receive cash
pursuant  to the Plan of  Exchange  will be a taxable  transaction  for  federal
income tax purposes under the Internal Revenue Code as amended ("the CODE"), and
may also be a taxable  transaction under applicable  state,  local and other tax
laws.

     In  general,  a  stockholder  will  recognize  gain  or loss  equal  to the
difference  between the tax basis of his shares and the amount of cash  received
under this exchange. Such gain or loss will be treated as a capital gain or loss
if the shares are capital assets in the hands of the stockholder.

     The tax consequences  described in the preceding paragraph may not apply to
(i) shares acquired upon the exercise of incentive stock options or otherwise as
compensation,  (ii) certain  non-resident  aliens and foreign  corporations  and
stockholders  who are subject to special tax treatment under the Code, and (iii)
any  stockholder  who now intends to utilize  installment  sale  treatment  with
respect to applicable gain realized upon them of payments under this exchange.

     The  federal  income  tax  consequences  set forth  above  are for  general
information.  Each  stockholder  is  urged to  consult  his own tax  advisor  to
determine the particular tax consequence to them of this exchange, including the
applicability and effect of state, local and other tax laws.

Dividends:

     The Company has never paid dividends and no dividends are in arrears.

Exhibit B

Fairness opinion; Report of:

Jeffrey J. Nelson
Wharton Valuation Associates, Inc.
704 River Road
West Trenton, NJ 08628
Dated May 12, 1999

We have conducted an analysis of Biosearch Medical Products, Inc.("Biosearch" or
the "Company")  for the purpose of determining  the fair value of 100 percent of
the Company's  outstanding  stock. It is our understanding that our analysis may
be used by the Company's Board of Directors in assessing the financial  fairness
of an offer to purchase all the Company's outstanding common stock.

It is our  understanding  that an offer of $0.20 per  share of common  stock has
been made by Hydromer,  Inc. We  understand  further that Hydromer has agreed to
assume approximately  one-half of the "change of control" obligation (not booked
on the  Company's  balance  sheet).  We  consider  this  offer to be fair from a
financial  point of view from the  perspective of the  stockholders of Biosearch
Medical Products, Inc.

We base this conclusion upon an analysis of financial  projections for Biosearch
out over the next five years,  as well as the prices being paid for companies in
the medical instrument industry.  With respect to out valuation of the Company's
projections,  we  applied  a  discount  rate  which  reflects  the  considerable
uncertainty  that the actual  results will not  materialize  as projected.  With
respect to the prices being paid for similar companies, we valued the Company at
the lower end of the range of multiples  (of revenue)  prevailing  in the market
place, again reflecting  relatively poor operating  history.  We also considered
the Company's  relatively thin equity  capitalization and poor operating results
for the first three months of 1999.

I hope this brief summary is of help to you and urge you to call if there is any
questions regarding it.

/ss/  Jeffrey J. Nelson, Managing Director

Exhibit B1.

Summary  of report  given to the  Biosearch  Board on April 29,  1999 by Wharton
Valuation Associates, Inc. (See Forward Looking Statements).

     Exhibit A was the balance  sheets of Biosearch for the fiscal years 1993 to
     1998 and a balance  sheet for  3/31/99.  The  figures  were  taken from the
     Company's filings with the S.E.C.

     Exhibit  B was a recap  of the  Income  statements  for the  same  years as
     Exhibit A.

Three Models were used to determine  the fair value of  Biosearch:  1 Discounted
Cash Flow; Comparative Sales and Liquidation Value Analysis.

DISCOUNTED CASH FLOW:

     Exhibit 1 was an analysis of present value of free cash flows projected out
     for 4.5 years based on  projection  supplied by Biosearch  and then further
     projected  for 17 more years based on an  assumption  of a 10% growth.  The
     Biosearch  projections are based on the business judgement of Mr. Martin C.
     Dyck,  President  and Mr.  Robert  Keller,  CFO of the  Company.  Biosearch
     projection indicate:

              1999           2000           2001           2002           2003
Sales     $1,855,300     $2,696,000     $3,526,000     $4,201,000     $4,851,000
Net Income   (74,152)       140,301        128,813        421,988        718,138

Based on certain  assumption of Federal  Income  Tax=34%,  State Income  Tax=9%,
Present  Value  Interest  Factor of 35%,  the  Enterprise  value  calculated  to
$275,361 or $0.125 per share.

Exhibit 2  contained  the same  information  except the Present  Value  Interest
Factor was set to 30%. It indicated  that the  Enterprise  value was $503,554 or
$0.229 per share

Exhibit 3 changed  the  Present  Value  Interest  Factor to 25%  indicating  the
Present Enterprise value was $858,011 or $0.391 per share.

COMPARATIVE ANALYSIS-SALES, MERGERS and ACQUISITIONS:

Exhibits 4 and 5 contained data on over 40 Companies. Based on averages of Price
to Revenue ratios,  Wharton concluded that the value of the Company was $530,345
or  $0.242  per  share.  If  an  average  was  computed  based  on  Sales/Merger
transactions the value of the Company would be $353,004 or $0.161 per share.

Exhibits 6,7 & 8 were summaries of the information in Exhibits 4&5.

LIQUIDATION:

Exhibit 9 calculated the liquidation  value as of 3/31/99 based on the Company's
balance sheet.

                 III. RELATIONSHIP WITH INDEPENDENT ACCOUNTANTS

     The Board of Directors has selected Amper,  Politziner & Mattia to serve as
independent  accountants for the Company for the fiscal year ending December 31,
1998. The Board of Directors considers this firm to be eminently qualified.

     A  representative  of Amper,  Politzner  & Mattia  will be  present  at the
Meeting with the opportunity to make a statement, if such representative desires
to do so, and will be available to respond to appropriate questions.

                                IV. OTHER MATTERS

     The Board of Directors  of the Company  does not know of any other  matters
which may be brought  before  the  Meeting.  However,  if any such  matters  are
properly  presented  for action,  it is the intention of the person named in the
accompanying form of Proxy to vote the shares represented  thereby in accordance
with their judgment on such matters.

                                V. MISCELLANEOUS

     If the accompanying  form of Proxy is executed and returned,  the shares of
Common Stock  represented  thereby will be voted in accordance with the terms of
the Proxy, unless the Proxy is revoked.

IMPORTANT

If no directions  are indicated in such Proxy,  the shares  represented  thereby
will be  voted  in the  election  of  directors  (Proposal  I) IN  FAVOR  OF the
individual  propose  by the  Board of  Directors  and in favor  of  Proposal  II
(Exchange [form of sale] of stock for $0.20/share).  Any Proxy may be revoked at
any time  before it is  exercised.  The  casting of a ballot at the Meeting by a
stockholder,  who may have  already  given a Proxy,  will  have  the  effect  of
revoking the same. A  stockholder  may revoke a proxy by notifying the Secretary
of  Biosearch in writing in any form signed by the  stockholder,  that the prior
proxy is revoked.

     All costs  relating  to the  solicitation  of Proxies  will be borne by the
Company.  Proxies  will be  solicited by the Company by mail and the Company may
pay brokers and other persons holding shares of stock in their names or those of
their nominees for their reasonable  expenses in sending soliciting  material to
their principals.

     It is important that Proxies be returned promptly.  Stockholders who do not
expect to attend the  Meeting in person  are urged to mark,  sign,  and date the
accompanying  form of Proxy and mail it in the enclosed return  envelope,  which
requires no postage if mailed in the United  States,  so that their votes can be
recorded.

Stockholder Proposals

     Stockholder  proposals  intended to be presented at the 2000 Annual Meeting
of Stockholders of the Company must be received by the Company by April 20, 2000

Mr. Kenneth P. Brice
Vice President of Finance
Hydromer, Inc.

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.

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

     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.

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.

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.

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.

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.

Biosearch Medical Products, Inc.                        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.

IN THIS CASE, THE DIFFERENCE BETWEEN THE COST AND BV RESULTS IN AN EXCESS WHICH
IS FIRST ATTRIBUED TO THE FAIR VALUE OF THE ASSETS OF BIOSEARCH. IF AFTER THE
ASSETS ARE WRITTEN UP THERE IS STILL A DIFFERENCE, THAT DIFFERENCE IS RECORDED
AS GOODWILL AND AMORTIZED OVER A LIFE NOT TO EXCEED 40 YEARS. IN THE EXAMPLE
ABOVE, IT IS ASSUMED THAT $50,000 IS ATTRIBUTABLE TO A FIXED ASSET INCREASE AND
THE REMAINDER IS RECORDED AS GOODWILL.
