Item 2.     Acquisition of Assets of ASI Liquidating Trust

      On May 9, 1996, the Registrant closed an acquisition of all of the
incontinence assets of the ASI Liquidating Trust (the "Trust"), the successor to
Advanced Surgical Intervention, Inc., including all assets relating to the
Miniguard Patch(TM), an United States Food and Drug Administration cleared
prescription adhesive patch placed against the external uretheral opening to
help to block leakage of urine in women with mild to moderate stress
incontinence. In consideration for the assets acquired from the Trust, the
Registrant paid to the Trust the amount of $7,000,000 in cash, issued to the
Trust 1,868,021 shares of its common stock, no par value ("Common Stock"), and
committed to issue an additional 467,005 shares of Common Stock, for a total of
2,335,026 shares of Common Stock, if a resale registration statement on Form S-3
filed with respect to such shares is declared effective within a designated
period (not to exceed 45 days) of its filing. In the event that the registration
statement on Form S-3 is not declared effective within such period, the
Registrant will be required to issue to the Trust an additional number of shares
of Common Stock if the market value of the Common Stock declines during the
period between the end of the designated period after the filing of the
registration statement and the effective date, not to exceed a maximum
additional number of shares equal in value to $4,600,000 on the effective date.
If the market value of the Common Stock increases during the same period, the
Registrant will issue fewer than 467,005 additional shares of Common Stock, so
as to offset the increase in value of the original aggregate 2,335,026 shares of
Common Stock from the end of the designated period to the effective date,
subject to a maximum decrease in the number of shares equal to $4,600,000 in
value on the effective date.

      The Registrant entered into Non-Competition and Consulting Agreements with
the co-inventors of the Miniguard Patch and one other significant former
employee of Advanced Surgical Intervention, Inc. pursuant to which such persons
agreed to assist the Registrant with the transition of the purchased assets to
the Registrant's operations and to assume certain non-competition obligations
for a period of three years after the closing date.

      THIS ASSET PURCHASE AGREEMENT is dated as of May 9, 1996, by and between

                                    Article 4

by this Agreement (the "Closing") shall be held on a date and time as shall be
mutually agreed to by the Buyer and the Seller, at the offices of Bingham, Dana
& Gould, 150 Federal Street, Boston, MA 02110, it being understood and agreed
that time is of the essence of this Agreement. The date on which the Closing is
actually held hereunder is sometimes referred to herein as the "Closing Date".

      4.2.  Transactions at Closing.  At the Closing:

            (a) The Sellers shall duly execute and deliver to the Buyer or its
      nominee or nominees such deeds, bills of sale, certificates of title and
      other instruments of assignment or transfer with respect to the Acquired
      Assets as the Buyer may reasonably request and as may be necessary to vest
      in the Buyer or its nominee(s) good record and marketable title to all of
      the Acquired Assets, in each case subject to no Excluded Liability and no
      Encumbrance (as defined in Section 5.11) except for Permitted Encumbrances
      (as defined in Section 5.11); these transfer instruments will include one
      or more Bills of Sale and Patent Assignments in the forms of Exhibits A
      and B hereto (collectively, the "Bills of Sale").

            (b) the Buyer shall deliver the Initial Cash Purchase Price by the
      wire transfer of immediately available funds to an account of the Sellers
      that has been designated for such purpose by the Sellers (with the Sellers
      making such designation at least 24 hours prior to the Closing); and the
      Buyer shall issue to the Seller that number of shares of UroMed
      Corporation common stock, no par value per share ("UroMed Common Stock"),
      rounded to the nearest whole number of shares, as shall equal the product
      of (x) the quotient of $23,000,000 divided by the Reference Market Value
      (as defined below) of a share of UroMed Common Stock, expressed in
      dollars, on the Closing Date (with such quotient referred to hereinafter
      as the "Firm Base Share Number"), multiplied by (y) 0.80 (the "Firm
      Shares"); provided, that in no event shall the Buyer be required to issue
      in excess of that number of shares of UroMed Common Stock equal to the
      difference between the number of shares of UroMed Common Stock authorized
      by the Articles of Organization of the Buyer, as amended from time to time
      (the "Buyer Articles"), and the number of shares of UroMed Common Stock
      issued and outstanding on the Closing Date; and provided, further, that in
      the event that the Buyer is prohibited from issuing shares of UroMed
      Common Stock pursuant to this Section 4.2(b), the Buyer shall pay to the
      Sellers an amount equal to the product of the number of shares of UroMed
      Common Stock which the Seller is so prohibited from issuing multiplied by
      the 



<PAGE>
                                      -5-

      Reference Market Value of a share of UroMed Common Stock on the
      Closing Date. For purposes of this Agreement, the "Reference Market Value"
      of a share of UroMed Common Stock with respect to a particular date shall
      mean the average closing sale price (in thousandths of dollars) on the
      NASDAQ National Market as reported under Composite Transactions in The
      Wall Street Journal for the five (5) trading days immediately preceding
      the date with respect to which the Reference Market Value is determined.

            (c)   [Intentionally omitted]

            (d) The Buyer, the Sellers, and the Indemnifying Beneficiaries shall
      execute a Registration Rights Agreement in the form of Exhibit C hereto
      (the "Registration Rights Agreement").

            (e) The Buyer and Robert F. Rosenbluth shall enter into a Consulting
      and Non-Competition Agreement in the form of Exhibit D-1 hereto (the
      "Rosenbluth Agreement").

            (f) The Buyer and Robert Greene shall enter into a Consulting and
      Non-Competition Agreement in the form of Exhibit D-2 hereto (referred to
      hereinafter collectively with the Rosenbluth Agreement as the "Consulting
      Agreements").

            (g) The Sellers shall deliver to the Buyer the written opinions of
      Stradling, Yocca, Carlson & Rauth, corporate counsel to the Sellers, and
      Klein & Szekeres, patent counsel to the Sellers, addressed to the Buyer
      and dated the Closing Date, in the respective forms of Exhibits E-1 and
      E-2, hereto.

            (h) The Buyer shall deliver to the Sellers the written opinion of
      Bingham, Dana & Gould LLP, counsel to the Buyer, dated the Closing Date
      and addressed to the Sellers, in the form of Exhibit F hereto.

      4.3   Issuance of Additional Shares.

            (a) In the event that the Registration Statement (as defined in the
      Registration Rights Agreement) is declared effective by the Securities and
      Exchange Commission (the "Commission") on or prior to the forty-fifth
      (45th) day following the later of the date of delivery of the Shareholder
      List (as defined in the Registration Rights Agreement) or the Closing Date
      (with such date referred to hereinafter as the "Reference Date"), the
      Buyer shall issue to the Sellers that nearest whole number of shares of
      UroMed Corporation Common Stock equal to difference of the Firm Base Share
      Number minus the number of Firm Shares.

            (b) In the event that the Registration Statement is not declared
      effective by the Commission on or prior to the Reference Date, on the day
      following the date on which the Registration Statement is declared
      effective by the Commission (the 


<PAGE>
                                      -6-

      "Effective Date"), the Buyer shall issue to the Sellers that nearest 
      whole number of shares of UroMed Common Stock, if any, equal to a number 
      of shares of UroMed Common Stock (but not less than zero) equal to (i)
      the product of the Firm Base Share Number multiplied by 0.20 plus or 
      minus (ii) an adjustment factor determined as follows:

            (I)   Subtract (x) the Reference Market Value of a share of UroMed
                  Common Stock on the Effective Date from (y) the Reference
                  Market Value of a share of UroMed Common Stock on the
                  Reference Date;

            (II)  Determine an aggregate dollar price adjustment equal to the
                  lesser of (x) the product of (i) the Firm Base Share Number
                  multiplied by (ii) 0.20 multiplied by (iii) the Reference
                  Market Value of a share of UroMed Common Stock on the Closing
                  Date, or (y) the product of the amount determined in step (I)
                  above multiplied by the Firm Base Share Number; and

            (III) Determine the aggregate-number-of-shares adjustment factor by
                  dividing the amount determined in step (II) above by the
                  Reference Market Value of a share of UroMed Common Stock,
                  expressed in dollars, on the Effective Date;

      provided, that in lieu of issuing to the Seller the positive number of
      Shares of UroMed Common Stock, if any, determined in step (III) above, the
      Buyer shall have the right, in its sole discretion, to pay to the Seller
      an amount in cash equal to the lesser of (i) the dollar amount determined
      in step (II) above or (ii) the dollar amount equal to the product of (x)
      the Firm Base Share Number multiplied by 0.20, multiplied by (y) the
      Reference Market Value of a share of UroMed Common Stock, expressed in
      dollars, on the Effective Date.

            (c) Notwithstanding the provisions of paragraphs (a) and (b) of this
      Section 4.3, in no event shall the Buyer be required to issue in excess of
      that number of shares of UroMed Common Stock equal to the difference
      between the number of shares of UroMed Common Stock authorized by the
      Buyer Articles and the number of shares of UroMed Common Stock issued and
      outstanding on the date on which such shares are issued. In the event that
      the Buyer is prevented from issuing shares of UroMed Common Stock pursuant
      to paragraphs (a) and (b) of this Section 4.3, the Buyer shall pay to the
      Seller an amount equal to the product of the number of shares of UroMed
      Common Stock which the Buyer is so prevented from issuing multiplied by
      the Reference Market Value of a share of UroMed Common Stock on the
      Closing Date, in the case of any issuances required under paragraph (a)
      above, or the Effective Date, in the case of any issuances required under
      paragraph (b) above.

                                    Article 5

    Representations and Warranties of the Sellers and Indemnifying Beneficiaries

      The Sellers and the Indemnifying Beneficiaries represent and warrant to
the Buyer as follows:

      5.1.  Organization; Authority.

            (a) The Sellers have full power and authority to enter into this
      Agreement, the Bills of Sale and the Registration Rights Agreement
      (collectively, the "Seller Acquisition Documents") and to perform their
      obligations hereunder and thereunder. Each Indemnifying Beneficiary has
      full power and authority to enter into this Agreement and the Registration
      Rights Agreement. The Sellers have full power and authority to own and
      hold the Acquired Assets. The nature of the businesses of the Sellers have
      not required them to be qualified or licensed in any jurisdiction.

            (b) The Sellers acquired all of the assets of ASI prior to its
      dissolution in 1994 pursuant to the Liquidating Trust Agreement. All Taxes
      (as defined below) and penalties payable or accrued by ASI under the
      California Bank and Corporation Tax Law have been paid and all other debts
      and liabilities (other than the Assumed Contracts and the Personal
      Property Leases) of ASI have been paid.

      5.2. Binding Effect. This Agreement and the rest of the Seller Acquisition
Documents have been duly authorized by all necessary actions of the Trustees and
beneficiaries of the Trust and this Agreement has been duly executed and
delivered by the Sellers and each Indemnifying Beneficiary and constitutes the
legal, valid and binding obligations of the Sellers and each Indemnifying
Beneficiary enforceable against them in accordance with its terms. The rest of
the Seller Acquisition Documents, when executed and delivered by the Sellers and
the Indemnifying Beneficiaries at the Closing, will constitute legal, valid and
binding obligations of the Sellers and each Indemnifying Beneficiary which is a
party thereto, enforceable against them in accordance with their terms.

      5.3. Non-Contravention. Neither the execution and delivery of this
Agreement and the rest of the Seller Acquisition Documents by the Sellers and
the Indemnifying Beneficiaries nor the consummation by the Sellers or any
Indemnifying Beneficiary of the transactions contemplated hereby or thereby will
constitute a violation of, or be in conflict with, or constitute or create a
default under, or result in the creation or imposition of any Encumbrance upon

the Sellers and the Indemnifying Beneficiaries, investigation is pending or, to
the knowledge of the Sellers and the Indemnifying Beneficiaries, threatened,
relating to or affecting any of the Acquired Assets, or which questions the
validity of this Agreement or any of the other Seller Acquisition Documents or

basis for any such action, suit, proceeding or investigation.

      5.9. Conformity to Law. The Sellers, insofar as it relates to any of the
Acquired Assets, have complied with, and are in compliance with (a) all laws,
statutes, governmental regulations and all judicial or administrative or
tribunal orders, judgments, writs, injunctions, decrees or similar commands

ordinance) and (b) all unwaived terms and provisions of all contracts,
agreements and indentures to which any of the Sellers or ASI is a party, or by
which any of the Sellers or any of the Acquired Assets is subject in either case
except where non-compliance would not have a material adverse effect on the
Acquired Assets or the ability of the Buyer to utilize the Acquired Assets. The
Sellers and ASI have not committed, been charged with, or to the knowledge of
the Sellers and the Indemnifying Beneficiaries, been under investigation with
respect to, nor does there exist, any violation of any provision of any

in 


<PAGE>
                                      -10-

any registry of deeds in any jurisdiction or under the Uniform Commercial Code 
or similar statute in any jurisdiction showing any of the Sellers as debtor
or consignee or lessee which create or perfect or which purport to create or
perfect any Encumbrance or other right, title or interest in or on any of the
Acquired Assets. Except as expressly provided in this Agreement, at and as of
the Closing, the Sellers will convey the Acquired Assets to the Buyer by deeds,
bills of sale, certificates of title and instruments of assignment and transfer
effective to vest in the Buyer, and the Buyer will receive, good and valid
record and marketable title to all of the Acquired Assets, free and clear of all

      5.12. Contracts. Except for the contracts, agreements and other
arrangements listed or described on Schedule 5.12, the Sellers are not a party
to or otherwise bound by any contract or agreement (oral or written) of any type
relating to any of the Acquired Assets. The Sellers have delivered or caused to
be delivered to the Buyer correct and complete copies of each contract,
agreement or other arrangement listed in Schedule 5.12 hereto, as amended to
date (the "Listed Contracts"). Each Listed Contract and each Assumed Contract is
a valid, binding and enforceable obligation of the Sellers, and, to the
knowledge of the Sellers and the Indemnifying Beneficiaries, the other party or
parties thereto, and is in full force and effect in all material respects.
Neither Seller nor, to the knowledge of the Sellers and the Indemnifying
Beneficiaries, the other party or parties thereto, is in breach or
non-compliance, or is considered to be in breach or non-compliance by the other
party thereto, of any term of any Listed Contract or any Assumed Contract. Since
January 1, 1995 the Sellers have not received any default notice or written
threat thereof with respect to any Listed Contract or any Assumed Contract and
neither Seller nor any Indemnifying Beneficiary has any reasonable basis for
suspecting that such action will be forthcoming. Subject to obtaining any
necessary consents to assignment by the other party or parties to any Listed
Contract or any Assumed Contract, no Listed Contract or Assumed Contract
includes or incorporates any provision the effect of which may be to enlarge or
accelerate any obligations of the Sellers or give additional rights to any other
party thereto or will in any other way be affected by, or terminate or lapse by
reason of, the transactions contemplated by this Agreement.

      profit-sharing, deferred compensation, share appreciation right,
      severance, group or individual health, dental, medical, life insurance,
      survivor benefit, car allowance, or similar plan, policy or arrangement,
      whether formal or informal, for the benefit of any employee of any Seller
      which is or was a Defined Benefit Plan as defined in Title IV of the
      Employee Retirement Income Security Act of 1974, as amended ("ERISA"). The
      Trust and ASI have never been a party to, bound by, or subject to any
      multi-employer plan.

            (b) Absence of Certain Events and Arrangements. Except as set forth
      in Schedule 5.15(b) hereto, no liability (contingent or otherwise) to the
      Pension Benefit Guaranty Corporation ("PBGC") or any multi-employer plan
      has been incurred by the Seller or any affiliate of any Seller (other than
      insurance premiums satisfied in due course).

            (c) Definitions. For purposes of this Section 5.16, "multi-employer
      plan," has the same meaning assigned such terms under ERISA, and

Sellers nor ASI had or has any employees. Neither the Sellers nor ASI has any

Person formerly employed by any Seller or ASI.

      5.17. Trademarks, Patents, Etc.

            (a) Schedule 5.17(a) hereto sets forth a complete and accurate list
      of all United States and foreign patents, patent applications, trademarks,
      trade names, trademark registrations and copyrights owned by and
      registered in the name of any of the Sellers or ASI and used or proposed
      to be used by any of the Sellers in connection with the Products or any of
      the other Acquired Assets, and all applications therefor. The IP
      Agreements represent the only agreements relating to Intellectual Property
      which any of the Sellers has licensed or authorized for use by others or
      which has been licensed or authorized for use in connection with the
      Products or the Acquired Assets.

            (b) Except to the extent set forth in Schedule 5.17(b) hereto, the
      Sellers own and have the sole and exclusive right to use all Intellectual
      Property used or necessary for the manufacture, sale and use of the
      Products, and any other Intellectual Property relating to the treatment of
      male or female incontinence developed by any employee of the Sellers or
      ASI while employed by such person and the consummation of the transactions
      contemplated hereby will not alter or impair any such right and will vest
      all rights, title and interest therein and thereto in the Buyer. The
      Sellers have the sole and exclusive right to manufacture, use and sell the
      Products. Schedule 5.17(b) lists all material inventions (whether
      patentable or nonpatentable) and trade secrets used by the Sellers in



<PAGE>
                                      -12-

      connection with or necessary to the manufacture, sale and use of the
      Products, and for each such listed invention or trade secret also lists,
      to the knowledge of the Sellers, the name and title of the person or
      persons responsible for the creation of such invention or trade secret. To
      the knowledge of the Sellers, all of the inventors of the inventions
      covered by the patents included in the Acquired Assets are correctly
      listed as the inventors thereon. Except as set forth in Schedule 5.17(b),
      (i) no royalties are paid or payable by the Sellers on or with respect to
      any of the patents or patent applications, inventions or trade secrets
      listed in Schedule 5.17(b), and upon the consummation of the transactions
      contemplated hereby, no additional royalties shall be payable with respect
      to such Intellectual Property, and (ii) each of the inventions and trade
      secrets listed in Schedule 5.17(b) hereto has, through assignment,
      agreement, operation of law or otherwise, become and is the sole property
      of the Sellers.

            (c) None of the Sellers nor the other party or parties thereto, is
      in breach of any IP Agreement. The Sellers have complied with all of its
      obligations of confidentiality in respect of the Intellectual Property of
      others, and to the knowledge of the Sellers and the Indemnifying
      Beneficiaries there are no violations of such obligations of
      confidentiality as are owed to the Sellers. No employee, agent or
      consultant of the Trust is subject to confidentiality restrictions in
      favor of any third Person the breach of which could subject the Sellers to
      any material liability or which could adversely affect the Seller's access
      to Intellectual Property previously used by it. No claims have been
      asserted, and no claims are pending, by any Person regarding use of any
      such Intellectual Property, or challenging or questioning the validity or
      effectiveness of any license or agreement relating to Intellectual
      Property, and there is no basis for such claim. To the knowledge of the
      Sellers and the Indemnifying Beneficiaries, the use by the Sellers of the
      Intellectual Property listed in any part of Schedule 5.17 does not
      conflict with or infringe on the rights of any Person and neither any
      Seller nor ASI has received any claim or written notice from any Person to
      such effect. To the knowledge of the Sellers and the Indemnifying
      Beneficiaries, no third party is infringing, violating or otherwise using,
      in an unauthorized manner, any Intellectual Property of the Sellers.

            (d) Set forth on Schedule 5.17(d) hereto is a complete list of all
      persons (including any consultants to the Sellers or ASI) who participated
      in the development and manufacture of the Product and the preparation of
      the FDA Application. Except as set forth on Schedule 5.17(d), each of such
      persons is party to a Confidentiality Agreement and Inventions Assignment
      Agreement in the form attached to Schedule 5.17(d) with the Sellers.
      Except as set forth on Schedule 5.17(d), no former employee of the Sellers
      or ASI owes any non-competition, non-solicitation or similar obligation to
      the Sellers or ASI.

      5.18. [Section 5.18 is intentionally omitted.]

      5.19. Fair Consideration; No Fraudulent Conveyance. After due inquiry and
investigation, the sale and purchase of the Acquired Assets pursuant to this
Agreement is made in exchange for fair and equivalent consideration. The Sellers
are not now insolvent and will not be 


<PAGE>
                                      -13-

rendered insolvent by the sale, transfer and assignment of the Acquired Assets
pursuant to the terms of this Agreement. The Sellers are not entering into this
Agreement with the intent to defraud, delay or hinder its creditors and the
consummation of the transactions contemplated by this Agreement will not have
any such effect. Neither ASI nor any Seller has ever admitted in writing its
inability to pay its debts generally as they become due, filed or consented to
the filing against it of a petition in bankruptcy or a petition to take
advantage of any insolvency act, made an assignment for the benefit of
creditors, consented to the appointment of a receiver for itself or for the
whole or any substantial part of its property, or had a petition in bankruptcy
filed against it, been adjudicated a bankrupt, or filed a petition or answer
seeking reorganization or arrangement under the federal bankruptcy laws or any
other laws of the United States or any other jurisdiction.

      5.20. Tax Matters.

            (a) Except as set forth in Schedule 5.20, (i) the Sellers have filed
      all Tax Returns (as defined in Article 11) which are required to be filed
      with any foreign, federal, state or local governmental authority or
      agency, and have paid, or made adequate provision for the payment of, all
      assessments received and all Taxes (as defined in Article 11) which have
      or may become due under applicable foreign, federal, state or local
      governmental law or regulations with respect to the periods in respect of
      which such Tax Returns were filed. The Sellers and the Indemnifying
      Beneficiaries know of no additional assessments since the date of such
      returns and reports.

            (b)   Except as set forth in Schedule 5.20:

                  (i) Liens.There  are no liens for Taxes  (other  than  current
            Taxes not yet due and payable) on any of the Acquired Assets;

                  (ii) Withholding Taxes. The Sellers have withheld and paid all
            Taxes required to have been withheld and paid in connection with
            amounts paid or owing to any employee, creditor, independent 
            contractor or other third party;  and

                  (iii) Foreign Permanent Establishments and Branches. Insofar
            as it relates to the Acquired Assets or the Product, the Sellers
            have no permanent establishment in any foreign country, as defined
            in the relevant tax treaty between the United States of America and
            such foreign country, and does not otherwise operate or conduct
            business through any branch in any foreign country.

      5.21. Product Liability. The Sellers have no liability (and there is no
basis for any present or future charge, complaint, action, suit, proceeding,
hearing, investigation, claim, or demand against the Sellers giving rise to any
liability) arising out of any injury to persons or property as a result of the
ownership, possession, or use of any product manufactured, sold, leased, or
delivered by the Sellers or ASI.

as of July 31, 1992, between ASI and the Serenity Business Unit of McNeill-PPC,
Inc. (the "Original J&J Agreement"), (ii) all amendments and modifications to
and terminations of the Original J&J Agreement, and (iii) all correspondence and
communications (including written summaries of any oral communications) between
ASI or any of the Sellers and Johnson & Johnson, Inc. which could have the
effect of modifying the Original J&J Agreement or which are material to the
relationship of the Sellers and the Serenity Business Unit of McNeill-PPC, Inc.

such trials.

      5.24. Competition. Except as set forth on Schedule 5.24 hereto, to the 
knowledge of Robert F. Rosenbluth (after a discussion with Robert Greene 
undertaken by Mr. Rosenbluth in good faith), there are no products being sold

treatment of female incontinence.

      5.25. Solicitation of Interest in Other Property of the Sellers. Except as

other representatives for the sale of any of the assets of the Sellers. Set

manufacture the Miniguard Product in sufficient quantities to support
commercialization and all materials needed to assemble the Miniguard Product and
its components are generally available from multiple sources without restriction

Clemente, California 92673, and have been adequately packaged for transfer to
the Buyer upon the Closing.

      5.30. Securities Act Matters.

            (a) The Sellers are acquiring the shares of UroMed Common Stock to
      be acquired by the Sellers pursuant to the transactions contemplated
      hereby (the "Shares"), for the Sellers' own account for investment and not
      with a view to the public distribution thereof. The Sellers acknowledge
      that the Shares are not registered under the Securities Act of 1933, as
      amended (the "Securities Act"), and agree that the Sellers will not sell
      or otherwise dispose of all or any portion of the Shares, otherwise than
      pursuant to registration under the Securities Act or under Rule 144
      promulgated thereunder or other similar rule if then available, without
      first obtaining (i) a written opinion of counsel satisfactory to counsel
      for the Buyer and addressed to the Buyer to the effect that the
      contemplated sale or other disposition of Shares will not be in violation
      of the Securities Act, or (ii) a "no-action" or interpretive letter from
      the Staff of the Securities and Exchange Commission (the "Commission"), to
      the effect that such Staff will take no action in respect of the
      contemplated sale or other disposition (a copy of which shall be furnished
      to the Buyer prior to any transfer of the Shares in question). In
      conformity herewith, the Seller(s) agree that the certificate(s) for all
      Shares issued hereunder shall bear the following legend:

                  "These securities have not been registered under the
            Securities Act of 1933 and may not be sold or otherwise disposed of,
            in whole or in part, other than pursuant to registration under said
            Act or in conformity with the limitations of Rule 144 or other
            similar rule as then in effect, without first obtaining (i) a
            written opinion of counsel satisfactory to the Company's counsel to
            the effect that the contemplated sale or other disposition will not
            be in violation of said Act or (ii) a 'no-action' letter from the
            Staff of the Securities and Exchange Commission to the effect that
            such Staff will take no action in respect of the contemplated sale
            or other disposition."

            The Sellers acknowledge that the Sellers were informed by the Buyer
      that because the Shares are unregistered, they must be held, and the
      economic risk of the investment 


<PAGE>
                                      -16-

      must be borne, indefinitely unless and until the Shares are subsequently 
      registered under the Securities Act or an exemption from such 
      registration is available.

            (b) The Sellers acknowledge that neither the offering of shares of
      UroMed Common Stock nor any offering literature used in connection
      therewith has been reviewed by the Commission or by the securities
      administrator of any state.

            (c) The Sellers have received copies of the Buyer's Annual Report on
      Form 10-K for its fiscal year ended December 31, 1995, the Buyer's 1995

                   Transitional Matters and Additional Covenants

      7.1. Undisclosed Assets. If the Buyer learns that any Seller failed
(whether or not inadvertently) to list any asset of such Seller needed for the
development, manufacture or sale of the Product or otherwise relating to male or
female incontinence, then the Buyer shall have the right to treat such asset as
an Acquired Asset for all purposes under this Agreement and as having been
transferred pursuant to the applicable Bill of Sale.

      7.2. Johnson & Johnson. The Sellers shall use their reasonable best
efforts to cause J&J to return to the Sellers for delivery to the Buyer all of
those Acquired Assets and any information which may be deemed to be confidential
information of the Sellers which may be in the possession of J&J.

      7.3. Return of Proprietary Information and Acquired Assets; Consulting
Agreements. Each Seller agrees to use its reasonable best efforts to (i) collect
all information and materials relating to the Product and the Acquired Assets in
the possession of the former employees of and consultants to the Sellers and ASI

Sellers for delivery to the Buyer any of the Acquired Assets in the hands of any
third party, (iii) cause the other parties to each of the Consulting Agreements

any continuations-in-part prepared and reasonably requested by the Buyer.

UroMed Common Stock under any registration statement filed pursuant to the
Registration Rights Agreement other than through any of PaineWebber
Incorporated, Vector Securities International, Inc. or Volpe, Welty & Company,

respective usual and customary broker's commissions.


                                    Article 8

                      Non-Competition and Related Covenants

      8.1.  Non-Competition.

            (a) The Sellers agree that for a period of five years after the
      Closing Date (the "Restricted Period"), none of the Sellers, nor any
      corporation, partnership or trust controlled directly or indirectly by
      such Seller, whether individually or as a consultant, partner, owner or
      stockholder owning more than five percent of a corporation, will engage
      directly or indirectly, within or outside the United States, in the
      business of developing, manufacturing or selling the Products, products
      having the same or similar functions, or products directly or indirectly
      competitive with the Products, including specifically any products
      relating to male or female incontinence. In addition, at no time in the
      future will any Seller, or any corporation, partnership or trust
      controlled, directly or indirectly, by such Seller, represent to any
      person that such Seller still owns or operates the business of developing,
      manufacturing or selling the Products, or is the successor in interest of
      such business.

            (b) The Sellers acknowledge that their obligations under this
      Section 8.1 are essential to the protection of the value to the Buyer of
      the Acquired Assets. It is recognized by the parties hereto that damages
      for breaches of covenants of the nature contained in this Section 8.1 are
      difficult if not impossible precisely to prove; therefore, it is agreed
      that this Agreement not to compete shall be enforceable by mandatory
      injunction, in addition to any other remedy available to the Buyer under
      this Agreement or at law or equity. If any of the restrictions contained
      in this Section 8.1 shall be deemed to be unenforceable by reason of the
      extent, duration or geographical scope or other provisions hereof, then
      the parties hereto contemplate that the court shall reduce such extent,
      duration, geographical scope or other provision hereof and enforce this
      Section 8.1 in its reduced form for all purposes in the manner
      contemplated hereby to the maximum extent permissible.

            (c) The provisions of this Article 8 shall not apply to any direct
      or indirect beneficiary of the Trust subject, in the case of Robert F.
      Rosenbluth and Robert Greene, to the provisions of the respective
      Consulting Agreements.

                            Confidential Information

      9.1.  Confidential Information.

            (a) During and after the Restricted Period, each Seller and each of
      the Indemnifying Beneficiaries and any corporation, partnership or trust
      controlled directly or indirectly by any of them shall keep, and the
      Sellers or such Indemnifying Beneficiary shall endeavor by agreement or
      otherwise to cause its employees, agents and representatives to keep,
      secret and retain in strictest confidence, and shall not use for the
      benefit of itself or others, any information relating to the Acquired
      Assets (the "Confidential Information"); provided that this Section 9.1
      shall not restrict disclosure by such Seller or any Indemnifying
      Shareholder of any Confidential Information required by applicable
      statute, rule or regulation or any court of competent jurisdiction,
      provided that the Buyer is given adequate advance written notice and an
      adequate opportunity to contest such disclosure, and any disclosure on a
      confidential basis to such Seller's attorneys, accountants and investment
      bankers, and shall not restrict any disclosure of information which is
      available publicly as of the date of this Agreement or which subsequently
      becomes available without breach of this or any other confidentiality
      obligation.

            (b) The Sellers acknowledge that their obligations under this
      Section 9.1 are essential to the protection of the value to the Buyer of
      the Acquired Assets. It is recognized by the parties hereto that damages
      for breaches of covenants of the nature contained in this Section 9.1 are
      difficult if not impossible precisely to prove; therefore, it is agreed
      that this Agreement not to compete shall be enforceable by mandatory
      injunction, in addition to any other remedy available to the Buyer under
      this Agreement or at law or equity. If any of the restrictions contained
      in this Section 9.1 shall be deemed to be unenforceable by reason of the
      extent or duration or other provisions hereof, then the parties hereto
      contemplate that the court shall reduce such extent or duration or other
      provision hereof and enforce this Section 9.1 in its reduced form for all
      purposes in the manner contemplated hereby to the maximum extent
      permissible.

      undertaking made by such Seller or Indemnifying Beneficiary in this
      Agreement or any of the other Seller Acquisition Documents;

            (ii) Without duplication, whether or not the event, circumstance or
      fact giving rise to Losses also constitutes a breach of any of the
      representations or warranties or covenants of the Sellers or any
      Indemnifying Beneficiary, any and all claims, liabilities and obligations
      arising out of the use of the Acquired Assets in the operation of any

            any Environmental Law on or prior to the Closing Date or (y) the
            release, emission or discharge on or prior to the Closing Date of
            any hazardous substance, toxic pollutants or other chemical
            by-products onto, from or into any real property presently or

            warranty or similar claims arising out of defects in any product
            sold or services performed by any of the Sellers or Indemnifying
            Beneficiary on or prior to the Closing Date;

Beneficiaries under this Article 10 shall be limited to the aggregate amount of
the Purchase Price allocable to such Indemnifying Beneficiary. The liability of
each of the Indemnifying Beneficiaries under this Article 10 as to each
individual Loss shall be limited to such Indemnifying Beneficiary's pro rata
share thereof (as reflected in Schedule 5.10 hereto) (as to each Indemnifying
Beneficiary, the "Pro Rata Share"). For all purposes of this Section 10.3 (and
solely for purposes of this Section 10.3):

<PAGE>
                                      -23-

         Beneficiary shall equal the sum of (i) that Indemnifying Beneficiary's 
         Pro Rata Share of the Initial Cash Purchase Price plus (ii) that 
         Indemnifying Beneficiary's Pro Rata Share of the product of the 
         closing sale price (in thousandths of dollars) on the NASDAQ National 
         Market as reported under Composite Transactions in The Wall Street
         Journal on the Effective Date multiplied by the total number of shares
         of UroMed Common Stock issued as payment of the Purchase Price (as set 
         forth in Section 3.1); and

     (b) each Indemnifying Beneficiary shall be treated as having incurred as
         a liability (and as having paid) its Pro Rata Share of any amount
         paid by the Sellers under this Article 10.

      10.4. Claims.

            (a) Any party seeking indemnification hereunder (the "Indemnified
      Party") shall promptly notify the other party hereto obligated to provide
      indemnification hereunder (the "Indemnifying Party") of any action, suit,
      proceeding, demand or breach (a "Claim") with respect to which the
      Indemnified Party claims indemnification hereunder, provided that failure
      of the Indemnified Party to give such notice shall not relieve any
      Indemnifying Party of its obligations under this Article 10 except to the
      extent, if at all, that such Indemnifying Party shall have been prejudiced
      thereby. If such Claim relates to any action, suit, proceeding or demand
      instituted against the Indemnified Party by a third party (a "Third Party
      Claim"), upon receipt of such notice from the Indemnified Party, the
      Indemnifying Party shall be entitled to participate in the defense of such
      Third Party Claim, and if and only if each of the following conditions is
      satisfied, the Indemnifying Party may assume the defense of such Third
      Party Claim, and in the case of such an assumption the Indemnifying Party
      shall have the authority to negotiate, compromise and settle such Third
      Party Claim:

                  (i) the Indemnifying Party confirms in writing that it is
            obligated hereunder to indemnify the Indemnified Party with respect
            to such Third Party Claim;

                  (ii) the Indemnified Party does not give the Indemnifying
            Party written notice that it has determined, in the exercise of its
            reasonable discretion, that a conflict of interest make separate
            representation by the Indemnified Party's own counsel advisable; and

                  (iii) the Indemnifying Party establishes to the reasonable
            satisfaction of the Indemnified Party that the Indemnifying Party
            has (and will continue to have) adequate financial resources to
            satisfy and discharge such action or claim.

<PAGE>
                                      -24-

            The Indemnified Party shall retain the right to employ its own
      counsel and to participate in the defense of any Third Party Claim, the
      defense of which has been assumed by the Indemnifying Party pursuant
      hereto, but the Indemnified Party shall bear and shall be solely
      responsible for its own costs and expenses in connection with such
      participation.

            (b) Notwithstanding the foregoing provisions of this Section 10.4,
      (i) no Indemnifying Party shall be entitled to settle any Third Party
      Claim without the Indemnified Party's prior written consent unless as part
      of such settlement the Indemnified Party is released in writing from all
      liability with respect to such Third Party Claim and (ii) no Indemnified
      Party shall be entitled to settle any Third Party Claim without the
      Indemnifying Party's prior written consent unless as part of such
      settlement the Indemnifying Party is released in writing from all
      liability with respect to such Third Party Claim.

            (c) In the event one party hereunder should have a claim for
      indemnification that does not involve a Third-Party Claim, the party
      seeking indemnification shall promptly send notice of such Claim to the
      other party. If the latter disputes such Claim, such dispute shall be
      resolved by agreement of the parties or by arbitration pursuant to Section
      12.14.

      10.5. Materiality Standards; Dollar Thresholds.

            (a) Neither the Sellers and the Indemnifying Beneficiaries, on the
      one hand, nor the Buyer, on the other hand, shall be liable to the other
      for any Claims for a breach of any of the representations and warranties
      set forth in Sections 5.1, 5.2, 5.4, 5.5, 5.6, 5.7, 5.8, 5.9, 5.12, 5.14,
      5.16, 5.18, 5.21, 5.22, 5.28, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6 (each a
      "Specified Misrepresentation Claim") if the total Losses of the Buyer or
      the Sellers with respect to such Specified Misrepresentation Claim do not
      exceed $10,000.

            (b) The Sellers and the Indemnifying Beneficiaries shall not be
      liable to the Buyer for any Specified Misrepresentation Claims unless and
      until the total Losses suffered by the Buyer with respect to all Specified
      Misrepresentation Claims exceeds $100,000, but then for such first
      $100,000 and to the extent of such excess.

            (c) Except as specifically set forth in paragraphs (a) and (b) no
      claim for indemnification under Section 10.1 or Section 10.2, shall be
      subject to any threshold amount or deductible amount.

      10.6. Method and Manner of Paying Claims; Set-Off. Subject to the
Indemnifying Party's right pursuant to Section 10.4 to defend, negotiate,
compromise and settle a Third Party Claim, the amount of any Claim shall be paid
by the Indemnifying Party forthwith on demand. Any amounts owed by the Buyer
(whether under this Agreement or otherwise) to the Sellers may be set off in
satisfaction of amounts owed to the Buyer by any Seller (whether under this



<PAGE>
                                      -25-

Agreement or otherwise), provided, that, the Buyer shall not be permitted to
delay the delivery of any shares of UroMed Common Stock pursuant to Section 4.3
pursuant to this Section 10.6.

      10.7. Insurance Proceeds.

            (a) No Indemnified Party shall be obligated to pursue or collect
      from any insurer prior to making a claim for indemnification pursuant to
      this Article 10 and no Indemnifying Party shall be entitled to postpone
      performance of any indemnification obligation under this Article 10 while
      an insurance claim is pending. However, without limiting any of the
      provisions of Sections 10.1 through 10.6, in connection with any matter
      subject to indemnification under this Article 10, all parties shall
      cooperate with each other in giving notice of any claim to any insurer
      (including an insurer of an Indemnified Party) and shall provide
      reasonable assistance in the collection of any such claim; provided,
      however, that there is no duty to provide notice, cooperate or assist with
      respect to an Indemnified Party's insurance policies where the Indemnified
      Party determines in its sole discretion that such notice, cooperation or
      assistance could invalidate any portion of the coverage available under
      such policy or result in the imposition of retroactive premiums or
      prospective premium increases. In addition, if an Indemnified Party makes
      such a determination after it has notified its insurer, it shall be
      entitled to retract such notice.

            (b) If an Indemnified Party actually receives insurance proceeds,
      the amount for which such Indemnified Party is entitled to indemnification
      under this Article 10 shall be reduced appropriately. In the event an
      Indemnified Party receives insurance proceeds after being paid by the
      Indemnifying Party with respect to an indemnifiable matter under this
      Article 10, the Indemnified Party will remit such proceeds to the
      Indemnifying Party, up to the amount previously paid by the Indemnifying
      Party with respect to such matter. Nothing in this Section 10.7 shall be
      deemed to waive or limit the subrogation rights of any insurer.

      10.8. Scope of Indemnity. The Sellers, the Buyer and each of the
Indemnifying Beneficiaries hereby acknowledge and agree that, after the Closing
and except for equitable relief before or after the Closing, including specific
performance, their sole and exclusive remedies with respect to any and all
claims relating to the subject matter of this Agreement shall be pursuant to the
indemnification provisions set forth in this Article 10.

      3.    Registration Procedures.

      The Company agrees to use its reasonable best efforts to effect the
registration of the Registrable Securities in accordance with the intended
method of disposition thereof, and pursuant thereto the Company will as
expeditiously as possible:

            (i)   use its  reasonable  best  efforts to cause the  Registration
      Statement, once filed in accordance with Section 2, to become effective;

            (ii) prepare and file with the Commission such amendments and
      supplements to the Registration Statement and the prospectus used in
      connection therewith as may be necessary to keep such registration
      statement effective until the earlier of (i) the second anniversary of the
      latest date of which shares of the Common Stock covered by such
      Registration Statement are issued by the Company, (ii) such time as all of
      the Common Stock covered by the Registration Statement have been sold, or
      (iii) such time that all Registrable Securities may be sold without
      limitation under the Securities Act, and to comply with the provisions of
      the Securities Act with respect to the disposition of all securities
      covered by the Registration Statement during such effective period in
      accordance with the intended methods of disposition by the sellers thereof
      set forth in the Registration Statement;

            (iii) prepare and file with the Commission up to a maximum of five
      (5) amendments or supplements, the appropriate form of such to be
      determined in the sole discretion of the Company, to amend the list of
      Selling Stockholders contained in the prospectus used in connection with
      the Registration Statement in the event that the Trustees and the Trust
      deliver to the Company an amendment to the Shareholder List (setting forth
      all of the information required to be contained in the original of the
      Shareholder List) in connection with a permitted transfer by the Trust or
      any Beneficiaries of any shares of Common Stock registered under the
      Registration Statement, other than by means of such Registration
      Statement;

            (iv) furnish to the Beneficiaries such number of copies of the
      Registration Statement, each amendment and supplement thereto, the
      prospectus included in the Registration Statement (including each
      preliminary prospectus) and such other publicly-available documents as the
      Beneficiaries may reasonably request in order to facilitate the
      disposition of the Registrable Securities covered by the Registration
      Statement;

            (v) notify the Beneficiaries, at any time when a prospectus relating
      thereto is required to be delivered under the Securities Act, of the
      happening of any event (without being required to disclose the nature of
      such event) as a result of which the prospectus included in the
      Registration Statement contains an untrue statement of a material fact or
      omits any fact necessary to make the statements therein not misleading
      and, at the request of the Trustees, the Company will promptly prepare
      (and, when completed, give notice to each seller of Registrable
      Securities) a 



<PAGE>
                                      -4-

      supplement or amendment to such prospectus so that, as thereafter 
      delivered to the purchasers of such Registrable Securities, such 
      prospectus will not contain an untrue statement of a material fact or
      omit to state any fact necessary to make the statements therein not
      misleading; provided that upon such notification by the Company, the
      Trust, each Trustee and each Beneficiary agrees that it will not, and each
      Beneficiary agrees that it shall cause any transferees of any Registrable
      Securities distributed to such Beneficiary not to, offer or sell any
      Registrable Securities until the Company has notified the Seller
      Representative that it has prepared a supplement or amendment to such
      prospectus and delivered copies of such supplement or amendment to the
      Seller Representative;

            (vi) cause all the Registrable Securities to be listed on each
      securities exchange on which securities of the same class issued by the
      Company are then listed;

            (vii) provide  a  transfer  agent  and  registrar  for  all  of the
      Registrable   Securities  not  later  than  the  effective  date  of  the
      Registration Statement; and

            (viii) in the event of the issuance of any stop order suspending the
      effectiveness of the Registration Statement, or of any order suspending or
      preventing the use of any related prospectus or suspending the
      qualification of any Registrable Securities included in the Registration
      Statement for sale in any jurisdiction, the Company will use its
      reasonable best efforts promptly to obtain the withdrawal of such order.

      4.    Registration Expenses.

      All expenses incident to the Company's performance of or compliance with
this Agreement, including without limitation all registration and filing fees,
fees and expenses of compliance with securities or blue sky laws, any fees
payable in connection with listing shares of Common Stock on the Nasdaq Stock

any annual audit or quarterly review, the expense of any liability insurance for
the Company and its board of directors and the expenses and fees for listing the
securities to be registered on each securities exchange on which similar

called "Registration Expenses"), will be borne by the Company. Notwithstanding
the foregoing, in the event of any underwritten offering including the
Registrable Securities, the Registration Expenses shall not include any
underwriting compensation or discount or any filing fees required to be paid to

payable in connection with listing shares of Common Stock on the Nasdaq Stock

      5.    Indemnification.

            (a) The Company agrees to indemnify, to the extent permitted by law,
      each holder of Registrable Securities, its officers and directors and each
      Person who controls such holder (within the meaning of the Securities Act)
      against all losses, claims, damages and liabilities caused by any untrue
      or alleged untrue statement of material fact contained in the Registration
      Statement, prospectus or preliminary prospectus or any amendment thereof
      or supplement thereto or any omission or alleged omission of a material
      fact required to be stated therein or necessary to make the statements
      therein not misleading, except insofar as the same are (i) caused by or
      contained in any information furnished in writing to the Company by such
      holder or the any Beneficiary expressly for use therein including, without
      limitation, the Shareholder List, (ii) caused by such holder's failure to
      deliver a copy of the Registration Statement or prospectus or any
      amendments or supplements thereto after the Company has furnished such
      holder or the Beneficiary from whom such holder received a distribution of
      Registrable Securities with a sufficient number of copies of the same,
      (iii) caused by such holder's sale of Registrable Securities in violation
      of the proviso to Section 3(v) hereof, or (iv) caused by the inaccuracy of
      any of the representations or warranties made by the Trust or the
      Beneficiaries, or any other information contained, in the Asset Purchase
      Agreement or any document delivered by the Trust or any Beneficiary in
      connection with the consummation of the transactions contemplated thereby.

            (b) In connection with the Registration Statement, each holder of
      Registrable Securities will furnish to the Company in writing such
      information and affidavits as the Company reasonably requests for use in
      connection with any such registration statement or prospectus and, to the
      extent permitted by law, the Trust and any Beneficiary from which such
      holder received any Registrable Securities will indemnify the Company, its
      directors and officers and each Person who controls the Company (within
      the meaning of the Securities Act) against any losses, claims, damages and
      liabilities resulting from any untrue or alleged untrue statement of
      material fact contained in the Registration Statement, prospectus or
      preliminary prospectus or any amendment thereof or supplement thereto or
      any omission or alleged omission of a material fact required to be stated
      therein or necessary to make the statements therein not misleading, but
      only to the extent that such untrue statement or omission is contained in
      any information or affidavit so furnished in writing by such holder or any
      Beneficiary; provided that the obligation to indemnify will be individual
      to the Beneficiary from which such holder received any Registrable
      Securities and will be limited to the net amount of any proceeds received
      by such holder or Beneficiary from the sale of Registrable Securities
      pursuant to the Registration Statement.

            (c) Any Person entitled to indemnification hereunder will (i) give
      prompt written notice to the indemnifying party of any claim with respect
      to which it seeks indemnification and (ii) unless in such indemnified
      party's reasonable judgment a 


<PAGE>
                                      -6-

      conflict of interest between such indemnified and indemnifying parties 
      may exist with respect to such claim, permit such indemnifying party to 
      assume the defense of such claim. If such defense is assumed, the 
      indemnifying party will not be subject to any liability for any 
      settlement made by the indemnified party without its consent (but such 
      consent will not be unreasonably withheld or delayed). An indemnifying 
      party who is not entitled to, or elects not to, assume the defense of a 
      claim will not be obligated to pay the fees and expenses of more than one
      counsel for all parties indemnified by such indemnifying party with 
      respect to such claim, unless in the reasonable judgment of any
      indemnified party a conflict of interest may exist between such
      indemnified party and any other of such indemnified parties with respect
      to such claim.

            (d) The indemnification provided for under this Agreement will
      remain in full force and effect regardless of any investigation made by or
      on behalf of the indemnified party or any officer, director or controlling
      Person of such indemnified party and will survive the transfer of the
      Registrable Securities.

      6.    Securities Act Matters.

      Each Beneficiary hereby severally represents and warrants to, and agrees
with, the Company as follows:

            (a) In the event that such Beneficiary receives a distribution of
      shares of Common Stock from the Trust, such Beneficiary shall acquire such
      shares of Common Stock (the "Shares"), for the Beneficiary's own account
      for investment and not with a view to the distribution thereof. The
      Beneficiary acknowledges and agrees that unless and until the Shares are
      registered under the Securities Act, the Beneficiary will not sell or
      otherwise dispose of all or any portion of the Shares, otherwise than
      pursuant to registration under the Securities Act or under Rule 144
      promulgated thereunder or other similar rule or exemption if then
      available, without first obtaining (i) a written opinion of counsel
      satisfactory to counsel for the Company and addressed to the Company to
      the effect that the contemplated sale or other disposition of Shares will
      not be in violation of the Securities Act, or (ii) a "no-action" or
      interpretive letter from the staff of the Commission (the "Staff"), to the
      effect that such Staff will take no action in respect of the contemplated
      sale or other disposition (a copy of which shall be furnished to the
      Company prior to any transfer of the Shares in question). In conformity
      herewith, the Beneficiary agrees that the certificate(s) for all Shares
      which may be issued to the Beneficiary from the Trust shall bear the
      following legend:

                  "These securities have not been registered under the
            Securities Act of 1933 and may not be sold or otherwise disposed of,
            in whole or in part, other than pursuant to registration under said
            Act or in conformity with the limitations of Rule 144 or other
            similar rule or exemption as then in effect, without first obtaining
            (i) a written opinion of counsel 


<PAGE>
                                      -7-

            satisfactory to the Company's counsel to the effect that the 
            contemplated sale or other disposition will not be in violation of 
            said Act or (ii) a 'no-action' or interpretive letter from the
            Staff of the Securities and Exchange Commission to the effect that 
            such Staff will take no action in respect of the contemplated sale 
            or other disposition."

            The Beneficiary acknowledges that the Beneficiary was informed by
      the Company that unless and until such Shares are registered for sale by
      such Beneficiary under the Securities Act, they must be held, and the
      economic risk of the investment must be borne, unless an exemption from
      such registration is available.

            (b) Such Beneficiary acknowledges that neither the sale of shares of
      Common Stock to the Trust by the Company, nor any distribution of the
      Shares to such Beneficiary, nor any offering literature used in connection
      therewith has been or will be reviewed by the Commission or by the
      securities administrator of any state.

            (c) Such Beneficiary has received copies of the Company's Annual
      Report on Form 10-K for its fiscal year ended December 31, 1995, the
      Company's 1995 Annual Report distributed to the Shareholders of the
      Company, and the Current Report on Form 8-K of the Company dated March 28,
      1996 (collectively, the "SEC Material"), and has carefully reviewed the
      SEC Material in its entirety. The Company has made available to the
      Beneficiary the opportunity to ask questions of, and receive answers from,
      the Company or persons acting on its behalf concerning the terms and
      conditions of the transactions contemplated by the Asset Purchase
      Agreement and the business and financial condition of the Company.

            (d) Such Beneficiary (i) is either an "accredited investor" as
      defined in Rule 501 promulgated under the Securities Act, or (ii) has such
      knowledge and experience in financial and business matters so that such
      Beneficiary is capable of evaluating the merits and risks of an investment
      in the Common Stock.

      7.    Restrictions on Sale of Common Stock.

            (a) The Trust, each Trustee, each Beneficiary agrees that it shall
      not, and it shall cause any permitted transferees of Registrable
      Securities not to, sell any shares of Registrable Securities under any
      Registration Statement filed pursuant to this Agreement other than through
      any of PaineWebber Incorporated, Vector Securities International, Inc. or
      Volpe, Welty & Company, provided that such brokers do not demand for such
      transactions more than their respective usual and customary broker's
      commissions.

            (b) The Company may suspend the use of any prospectus contained in
      any Registration Statement for periods not to exceed seven business days
      in any three month period or four periods not to exceed an aggregate of 28
      business days in any 12 month period in the event that the Company
      determines, in the exercise


<PAGE>
                                      -8-

      of its reasonable discretion, that sales of Registrable Securities 
      thereunder could constitute violations of the Securities Act.

      8.    Miscellaneous.

            (a) Remedies. Any Person having rights under any provision of this
      Agreement will be entitled to enforce such rights specifically, to recover
      damages caused by reason of any breach of any provision of this Agreement
      and to exercise all other rights granted by law. The parties hereto agree
      and acknowledge that money damages may not be an adequate remedy for any
      breach of the provisions of this Agreement and that any party may in its
      sole discretion apply to any court of law or equity of competent
      jurisdiction (without posting any bond or other security) for specific
      performance and for other injunctive relief in order to enforce or prevent
      violation of the provisions of this Agreement.

            (b) Amendments and Waivers. Except as otherwise provided herein, the
      provisions of this Agreement may be amended or waived only upon the prior
      written consent of the Company and the holders of a majority of the
      Registrable Securities (if, and only to the extent that, the rights and
      obligations of such parties hereto are adversely affected).

            (c) Successors and Assigns. All covenants and agreements in this
      Agreement by or on behalf of any of the parties hereto will bind and inure
      to the benefit of the respective successors and permitted assigns of the
      parties hereto whether so expressed or not.

            (d) Severability. Whenever possible, each provision of this
      Agreement will be interpreted in such manner as to be effective and valid
      under applicable law, but if any provision of this Agreement is held to be
      prohibited by or invalid under applicable law, such provision will be
      ineffective only to the extent of such prohibition or invalidity, without
      invalidating the remainder of this Agreement.

            (e) Counterparts. This Agreement may be executed simultaneously in
      two or more counterparts, any one of which need not contain the signatures
      of more than one party, but all such counterparts taken together will
      constitute one and the same Agreement.

            (f) Descriptive  Headings. The descriptive headings of this
      Agreement are inserted for convenience only and do not constitute a
      part of this Agreement.

            (g) GOVERNING  LAW.   THIS   AGREEMENT   AND  THE  EXHIBITS  AND
      SCHEDULES  HERETO WILL BE GOVERNED BY AND  CONSTRUED IN  ACCORDANCE  WITH
      THE INTERNAL LAW, AND NOT THE LAW OF CONFLICTS,  OF THE  COMMONWEALTH  OF
      MASSACHUSETTS.

            (h) WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY
      IRREVOCABLY WAIVES ANY RIGHTS THAT IT MAY HAVE TO A TRIAL BY JURY IN
      RESPECT OF ANY LITIGATION BASED UPON, OR ARISING OUT OF, THIS AGREEMENT
      AND THE TRANSACTIONS CONTEMPLATED HEREBY OR ANY COURSE OF CONDUCT, COURSE
      OF DEALING, STATEMENTS OR ACTIONS OF ANY OF THEM RELATING HERETO OR
      THERETO.

            (i)   Attorney's  Fees.   Reasonable   attorney's  fees  and  costs
      shall be  awarded  to the  prevailing  party by the  court in  connection
      with any action taken to enforce rights under this Agreement.

            (j) Notices. All notices, demands or other communications to be
      given or delivered under or by reason of the provisions of this Agreement
      shall be in writing and shall be deemed to have been given (i) if mailed
      by certified or registered mail, postage prepaid, return receipt

                                                       Asset Purchase Agreement


                                 CONSULTING AND
                            NON-COMPETITION AGREEMENT



      The parties to this agreement, dated as of May 9, 1996, are UroMed
Corporation, a Massachusetts corporation with a principal place of business at
64 A Street, Needham, Massachusetts 02194 ("UroMed"), and Robert F. Rosenbluth,
an individual residing at 24161 Cherry Hills Place, Laguna Niguel, CA 92677
("Consultant").

      The parties are entering into this agreement in accordance with the Asset
Purchase Agreement dated as of May 9, 1996 between UroMed, The ASI Liquidating
Trust (the "Trust"), the Consultant, and certain other persons (the "Asset
Purchase Agreement").

      The Consultant irrevocably agrees and acknowledges as follows:

   (bullet) that his execution and delivery of this agreement and his
            performance of his obligations under this agreement are part of the
            consideration received and to be received by UroMed in exchange for
            its payments under the Asset Purchase Agreement;

   (bullet) that UroMed and the other parties to the Asset Purchase Agreement
            are relying on the Consultant's execution, delivery, and performance
            of this agreement in entering into the Asset Purchase Agreement and
            in carrying out their obligations under that agreement;

   (bullet) that the Consultant's execution and delivery of this agreement is a
            condition precedent to UroMed's obligations under the Asset Purchase
            Agreement;

   (bullet) that he is a beneficiary of the Trust and, as such, will directly
            benefit from the transactions contemplated by the Asset Purchase
            Agreement; and

   (bullet) that the foregoing, in addition to UroMed's agreements and
            obligations under this agreement, represent sufficient, full, fair,
            and adequate consideration for the Consultant's agreements under
            this agreement.


      1.    Consulting Relationship.

            (a) UroMed hereby retains Consultant as a consultant to UroMed, and
Consultant hereby accepts such consulting arrangement, for the period and upon
the terms and conditions set forth herein.

            (b) Subject to the general direction and control of UroMed,
Consultant shall use his best efforts, including the highest standards of
professional competence and integrity, in the consulting relationship
established hereby, on the terms set forth herein. Consultant's specific duties
shall be to provide such transitional, technological, manufacturing and business
advice and assistance as UroMed may request relating to the Product and the
Acquired Assets (as those terms are defined in the Asset Purchase Agreement),
and the establishment of UroMed's business relating thereto. UroMed and the
Consultant intend that it shall be the goals of the consulting relationship
created hereby to (i) advise on 


<PAGE>
                                      -2-

the efficacy and marketability of the Products, (ii) assist in the development
of UroMed's ability to manufacture in sufficient quantities Products utilizing
the Acquired Assets, (iii) assist UroMed in obtaining all necessary regulatory
approvals to market the Products in the United States and abroad, and (iv) , if
appropriate, assist UroMed in improving its intellectual property position with
respect to the Products and the Acquired Assets. The consulting services could
also include, at the request of UroMed, introducing representatives of UroMed to
certain suppliers, customers and other persons with whom the Consultant had
contact during his employment by or other affiliation with Advanced Surgical
Intervention, Inc. It is understood and agreed that Consultant shall provide
such services to UroMed as follows:

                  (i) solely at UroMed's request, five (5) complete days of
      full-time consulting services at UroMed's headquarters in Needham,
      Massachusetts during the five months following the date hereof, on such
      days as the Consultant and UroMed shall agree;

                  (ii) solely at UroMed's request, up to two (2) hours during
      each full or partial calendar week thereafter through and including the
      calendar week ending August 9, 1996;

                  (iii) solely at UroMed's request, up to one (1) hour during
      each calendar week thereafter through and including the calendar week
      ending November 14, 1997; and

                  (iv) at UroMed's request and upon the agreement of the
      Consultant, at such other times and for such periods as UroMed and the
      Consultant shall mutually agree.

The Consultant agrees, subject to reasonable delay on the basis of his existing
commitments (not to exceed four weeks in any event), to perform such services
when and where requested by UroMed. The services to be provided under clauses
(ii), (iii) and (iv) above may be provided by telephone call with one or more
authorized representatives of UroMed or in person at such location or locations
as the parties may mutually agree, and may be provided during regular business
hours (Eastern Standard Time or Eastern Daylight Time, as applicable) or at such
other times as the parties may mutually agree. If in any calendar week described
in clauses (ii) and (iii) above the Consultant provides more, or is requested to
provide less, than two (2) hours or one (1) hour of services (as applicable)
such excess or requested shortfall shall not reduce or increase the Consultant's
obligations in any subsequent calendar week. It is understood and agreed by the
Consultant and UroMed that UroMed is under no obligation to request any
consulting services from the Consultant.

            (c) UroMed and Consultant are not partners or joint venturers with
each other with respect to the matters subject to this agreement and nothing
herein shall be construed so as to make them such partners or joint venturers or
to impose any liability as such on either of them. Consultant is, and shall
remain at all times during the term of this agreement, an independent contractor
of UroMed with no power or authority to bind or contract for UroMed, to execute
any contract or other agreement, instrument, or document on behalf of UroMed, or
to make or suffer the creation of any lien, charge, pledge or hypothecation of
any property of UroMed, unless specifically granted such authority in writing.
Nothing contained herein shall cause Consultant by reason of the consulting
relationship obtained hereby to be deemed an employee, officer, or director of
UroMed. Accordingly, the parties hereto recognize that the outcome of
Consultant's activities, and not the method of performance of his obligations
hereunder, is subject to the control of UroMed.

      2. Reimbursement of Expenses. UroMed shall promptly reimburse Consultant
for all ordinary and necessary expenses incurred by the Consultant on behalf of
UroMed and authorized in 


<PAGE>
                                      -3-

advance by UroMed, upon the presentation of customary vouchers and reimbursement
slips. Consultant shall have no rights to any compensation or benefits except as
specifically set forth herein, and nothing set forth in this Section 2 shall
limit or restrict the rights of UroMed under Section 3 hereof.

      3. Term. This agreement shall take effect as of the date first above
written, and shall remain in effect until the end of the day on the date set
forth in Section 1(b)(iii). Notwithstanding anything else contained in this
agreement, however, the provisions of Sections 4 through 9 hereof shall survive
the termination of this agreement and of Consultant's consulting relationship
hereunder.

      4. Assignment of Rights to Proprietary Information and Inventions.
Consultant recognizes that UroMed possesses or will possess information that has
commercial value in UroMed's business ("Proprietary Information") including
without limitation, information created, discovered or developed directly or
indirectly by Consultant prior to the transactions contemplated by the Asset
Purchase Agreement or in connection with Consultant's services hereunder, or
made known to Consultant during the term hereof. Consultant acknowledges that
such Proprietary Information shall include, without limitation, the information
included in the Acquired Assets and Intellectual Property (as such terms are
defined in the Asset Purchase Agreement), inventions, product improvements,
financial, technical or sales strategies, forecasts, product ideas, formulas,
processes, copyrightable and/or patentable materials and/or concepts,
schematics, techniques, market research and/or customer lists which Consultant
may create or be exposed to from time to time relating to male or female
incontinence. Consultant expressly agrees that all Proprietary Information and
rights thereto shall be and remain the sole and exclusive property of UroMed,
and Consultant hereby without further consideration, unconditionally,
exclusively and irrevocably assigns to UroMed, royalty free, all of his right,
title and interest in such Proprietary Information. Notwithstanding the
foregoing, Consultant shall assist UroMed in every proper way to obtain for
UroMed's benefit patents and other Proprietary Information relating to the
Acquired Assets in the United States and in foreign countries, such assistance
to include executing and delivering such confirmatory instruments of this
assignment as UroMed may request including, without limitation, applications for
patent and/or copyright registration. Consultant agrees that the foregoing
assignments are a material term of his consulting relationship with UroMed and
that his consulting fee and the terms of the Asset Purchase Agreement include
sufficient consideration therefor.

      5. Confidentiality. At all times during the term of this agreement and
thereafter (including periods after the termination or expiration of
Consultant's consulting relationship with UroMed) Consultant shall keep in
strictest confidence and trust all Proprietary Information and will not use,
discuss or disclose any Proprietary Information without the prior written
consent of UroMed, except when done in the course of his consulting relationship
exclusively with other UroMed employees and consultants. The foregoing
restriction shall not apply to Proprietary Information that Consultant can
clearly demonstrate to have been in the public domain prior to the date hereof
or that comes into the public domain during the operation hereof through no
fault of Consultant. Consultant agrees that his consulting fee hereunder and the
benefits he will realize under the Asset Purchase Agreement include sufficient
consideration for the foregoing covenants.

      6. Return of Materials. Upon the termination or expiration of Consultant's
consulting relationship with UroMed, Consultant shall immediately deliver to the
President of UroMed all files, notes, lists, rolodex cards, credit cards,
computer disks, recordings, print-outs, and drawings (including, without
limitation, any materials reflecting or containing Proprietary Information) that
are under the control or in the possession of Consultant and relate to the
operation and business of UroMed. Consultant shall not be entitled to retain any
duplicates of the foregoing.

                                      -4-

      7.    Non-Competition; Assignment of Restricted Inventions.

            (a) Consultant agrees that for a period of three (3) years after the
Closing Date (as that term is defined in the Asset Purchase Agreement),
Consultant will not directly (as owner, partner, principal in any entity or
otherwise) or indirectly (as an employee, agent, contractor, advisor,
beneficiary or otherwise) engage in, or participate in any entity that engages
in, any activity involving the development, manufacturing or marketing of any
product, product concept, service or service concept in the area of non-surgical
male and female incontinence technology (including without limitation the
Products, as that term is defined in the Asset Purchase Agreement). Consultant
acknowledges that UroMed's business is global in nature and therefore agrees
that the foregoing restrictions apply both within and outside the United States.

            (b) Until the expiration of the period referred to in subsection (a)
above, Consultant shall provide UroMed with written notice (i) of any change of
Consultant's residential address or employment.

            (c) Until the expiration of the period referred to in subsection (a)
above, Consultant agrees not to seek to persuade any UroMed employee,
consultant, director, officer or advisory board member to discontinue
association with UroMed or become involved directly or indirectly in any
endeavor that Consultant is restricted from engaging in under subsection (a)
above.

            (d) Consultant agrees that he will promptly notify UroMed in writing
of any technology, invention, discovery, concept, and/or idea, whether or not
patentable or copyrightable, developed by Consultant prior to the expiration of
the period referred to in subsection (a) above that relates or may relate to any
endeavor that Consultant is restricted from engaging in under subsection (a)
above ("Restricted Inventions"). UroMed is hereby irrevocably granted the option
to take an unconditional, exclusive, irrevocable, royalty-free assignment of
such Restricted Invention(s) upon written notice mailed to Consultant within
thirty (30) days after UroMed's receipt of Consultant's initial notice. If
UroMed duly exercises such option, Consultant shall execute and deliver such
instruments of assignment therefor as UroMed may deem necessary or advisable
including, without limitations, applications for patent and/or copyright
registration.

            (e) Consultant represents and warrants for UroMed's reliance that
the foregoing covenants in subsections (a) through (d) above will not unduly
impair Consultant's ability to obtain gainful employment or consulting
relationships in Consultant's field during or subsequent to Consultant's
consulting relationship with UroMed. Consultant further agrees that his
consulting fee hereunder and the benefits he will realize under the Asset
Purchase Agreement include sufficient consideration for the restrictions imposed
by the foregoing covenants.

      8. Consultant Representations. Consultant represents and warrants for
UroMed's reliance that (i) this agreement does not conflict with any other
agreement, promise and/or commitment undertaken by Consultant that could
prohibit or impair the performance of Consultant's obligations hereunder; (ii)
Consultant has not and shall not disclose to UroMed, its officers, directors,
employees or agents any proprietary information of another individual or company
prohibiting such disclosure; (iii) Consultant's compliance with the
confidentiality, non-competition and other provisions of this agreement will not
materially impair Consultant's ability to earn a living outside of UroMed in his
field; and (iv) all information on Consultant's education, past work experience
and other qualifications presented to UroMed are accurate, complete and not
misleading.

                                      -5-

      9. Indemnification. UroMed agrees to indemnify and hold Consultant
harmless for any losses of Consultant caused by any injury resulting from the
use of the Acquired Assets (as defined in the Asset Purchase Agreement) or any
products or inventions or improvements thereto arising from this consulting
relationship designed by Consultant.

      10.   Miscellaneous.

            (a) Each of the Consultant and UroMed represents that he or it has
not used any employment counselor or other person who would be entitled to any
compensation for arranging or obtaining the consulting relationship hereby
obtained.

            (b) All notices and other communications hereunder shall be in
writing or by written telecommunication, and shall be deemed to have been duly
given if delivered personally or if mailed by certified mail, return receipt
requested, postage prepaid, or if sent by nationally recognized reputable
overnight courier (e.g., FedEx), or by facsimile confirmed by one of the other
methods of giving notice hereunder, to the relevant address set forth in the
preamble hereto, or to such other address as the recipient of such notice or
communication shall have specified to the other party hereto in accordance with
this Section 9(b). All such notices shall be deemed given upon receipt if
delivered personally or by facsimile confirmed as provided above, or five (5)
days after mailing if mailed by certified mail, or one (1) day after mailing if
sent by nationally recognized reputable overnight courier.

            (c) Consultant agrees that any breach of Section 4 through 7,
inclusive, will result in irreparable damage to UroMed and therefore consents
that in addition to any other remedies it may have (including without limitation
recovery of provable damages and reasonable attorneys' fees) UroMed will be
entitled to enjoin any such breach in any court of competent jurisdiction.

            (d) The parties acknowledge that this agreement constitutes the
complete agreement of the parties concerning the subject matter hereof and
concerning the Consultant's consulting relationship with UroMed and all offer
letters, negotiations and other agreements are superseded and extinguished
hereby. No modification or amendment hereof shall be valid or enforceable unless
it is in writing and executed and delivered by the parties. The waiver by any
party of a breach of any provision of this agreement shall not operate or be
construed as a waiver of any subsequent breach.

            (e) If any provision in this agreement is found unenforceable, it
shall not affect any other provisions hereof. If any provision in this agreement
is determined to be unenforceable, it shall be construed by limiting it so as to
be enforceable to the fullest extent compatible with applicable law and so as to
give effect to the fullest extent possible the agreement of the parties as
evidenced by this agreement.

            (f) This agreement shall bind and inure to the benefit of the
parties and any successor of UroMed by reorganization, merger, consolidation,
liquidation, sale or other assignment of UroMed's business or assets. The
Consultant may not assign any of his duties and obligations under this
agreement.

            (g) This agreement shall be governed by and construed in accordance
with the internal substantive laws of the Commonwealth of Massachusetts.

                                      -6-

            (h) This agreement may be executed in multiple counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

      IN WITNESS WHEREOF, and intending to be legally bound hereby, the parties
hereto have caused this agreement to be duly executed as of the date and year
first above written.

                            NON-COMPETITION AGREEMENT

      The parties are entering into this agreement in accordance with the Asset
Purchase Agreement dated as of May 9, 1996 between UroMed, The ASI Liquidating
Trust (the "Trust"), and certain other persons (the "Asset Purchase Agreement").
The Consultant acknowledges: that he is a beneficiary of the Trust and, as such,

      1.    Consulting Relationship.

            (a) UroMed hereby retains Consultant as a consultant to UroMed, and
Consultant hereby accepts such consulting arrangement, for the period and upon
the terms and conditions set forth herein.

            (b) Subject to the general direction and control of UroMed,
Consultant shall use the highest standards of professional competence and
integrity in the consulting relationship established hereby, on the terms set
forth herein. Consultant's specific duties shall be to provide such
transitional, technological, manufacturing and business advice and assistance as
UroMed may request relating to the Product and the Acquired Assets (as those
terms are defined in the Asset Purchase Agreement), and the establishment of
UroMed's business relating thereto. It shall be the goals of the consulting
relationship created hereby to (i) improve the efficacy and marketability of the
Products, (ii) assist in the development of UroMed's ability to manufacture in
sufficient quantities Products utilizing the Acquired Assets, (iii) assist
UroMed in obtaining all necessary regulatory approvals to market the Products in
the United States and abroad, and (iv), if appropriate, assist UroMed in
improving its intellectual property position with respect to the Products and
the Acquired Assets. The consulting services could also include, at the request
of UroMed, introducing representatives of UroMed to certain suppliers, customers
and other persons with whom the Consultant had contact during his affiliation
with Advanced Surgical Intervention, Inc. It is understood and agreed that
Consultant shall provide such services to UroMed as follows:

<PAGE>
                                      -2-

                  (iii) at UroMed's request and upon the agreement of the
      Consultant, at such other times and for such periods as UroMed and the
      Consultant shall mutually agree.

The services to be provided under clauses (ii) and (iii) above may be provided
by telephone call with one or more authorized representatives of UroMed or in
person at such location or locations and at such times as the parties may
mutually agree. If in any calendar week described in clause (ii) above the
Consultant provides more, or is requested to provide less, than two (2) hours of
services, such excess or requested shortfall shall not reduce or increase the
Consultant's obligations in any subsequent calendar week. It is understood and
agreed by the Consultant and UroMed that UroMed is under no obligation to
request any consulting services from the Consultant.

            (c) UroMed and Consultant are not partners or joint venturers with
each other with respect to the matters subject to this agreement and nothing
herein shall be construed so as to make them such partners or joint venturers or
to impose any liability as such on either of them. Consultant is, and shall
remain at all times during the term of this agreement, an independent contractor
of UroMed with no power or authority to bind or contract for UroMed, to execute
any contract or other agreement, instrument, or document on behalf of UroMed, or
to make or suffer the creation of any lien, charge, pledge or hypothecation of
any property of UroMed, unless specifically granted such authority in writing.
Nothing contained herein shall cause Consultant by reason of the consulting
relationship obtained hereby to be deemed an employee, officer, or director of
UroMed. Accordingly, the parties hereto recognize that the outcome of
Consultant's activities, and not the method of performance of his obligations
hereunder, is subject to the control of UroMed.

      2. Compensation. In return for his services hereunder, and in addition to
the benefits to be realized by the Consultant under the Asset Purchase
Agreement, Consultant shall be paid in arrears, in such manner as UroMed may
determine (but no less often than monthly), upon submission of appropriate
documentation to UroMed (as UroMed may reasonably determine), the amount of ONE
HUNDRED DOLLARS ($100.00) PER HOUR of services rendered hereunder (prorated for
partial hours of services and excluding commuting time, if any), without
deduction or withholding of any federal, state, or local taxes; Consultant shall
be solely responsible for all federal, state, and local taxes due in respect
thereof and all other deductions required by law. In addition, UroMed shall
promptly reimburse Consultant for all ordinary and necessary expenses incurred
by the Consultant on behalf of UroMed and authorized in advance by UroMed, upon
the presentation of customary vouchers and reimbursement slips. Consultant shall
have no rights to any compensation or benefits except as specifically set forth
herein, and nothing set forth in this Section shall limit or restrict the rights
of UroMed under Section 3 hereof.

      3. Term. This agreement shall take effect as of the date first above
written, and shall remain in effect until the end of the day on the date set
forth in Section 1(b)(ii). Notwithstanding anything else contained in this
agreement, however, the provisions of Sections 4 through 9 hereof shall survive
the termination of this agreement and of Consultant's consulting relationship
hereunder.

      4. Assignment of Rights to Proprietary Information and Inventions.
Consultant recognizes that UroMed possesses or will possess information that has
commercial value in UroMed's business ("Proprietary Information") including
without limitation, information created, discovered or developed directly or
indirectly by Consultant prior to the transactions contemplated by the Asset
Purchase Agreement or in connection with Consultant's services hereunder, or
made known to Consultant during the term hereof. Consultant acknowledges that
such Proprietary Information shall 


<PAGE>
                                      -3-

include, without limitation, the information included in the Acquired Assets and
Intellectual Property (as such terms are defined in the Asset Purchase
Agreement), inventions, product improvements, financial, technical or sales
strategies, forecasts, product ideas, formulas, processes, copyrightable and/or
patentable materials and/or concepts, schematics, techniques, market research
and/or customer lists which Consultant may create or be exposed to from time to
time, and which relate to the non-surgical treatment of male or female
incontinence. Consultant expressly agrees that all Proprietary Information and
rights thereto shall be and remain the sole and exclusive property of UroMed,
and Consultant hereby without further consideration, unconditionally,
exclusively and irrevocably assigns to UroMed, royalty free, all of his right,
title and interest in such Proprietary Information. Notwithstanding the
foregoing, Consultant shall assist UroMed in every proper way to obtain for
UroMed's benefit patents and other Proprietary Information relating to the
Acquired Assets in the United States and in foreign countries, such assistance
to include executing and delivering such confirmatory instruments of this
assignment as UroMed may request including, without limitation, applications for
patent and/or copyright registration. Consultant agrees that the foregoing
assignments are a material term of his consulting relationship with UroMed and
that his consulting fee and the terms of the Asset Purchase Agreement include
sufficient consideration therefor. Notwithstanding the foregoing, the
Proprietary Information shall not include the information set forth on Exhibit A
hereto.

      5. Confidentiality. At all times during the term of this agreement and for
three (3) years thereafter (including periods after the termination or
expiration of Consultant's consulting relationship with UroMed) Consultant shall
keep in strictest confidence and trust all Proprietary Information and will not
use, discuss or disclose any Proprietary Information without the prior written
consent of UroMed, except when done in the course of his consulting relationship
exclusively with other UroMed employees and consultants. The foregoing
restriction shall not apply to Proprietary Information that consultant can
clearly demonstrate to have been in the public domain prior to the date hereof
or that comes into the public domain during the operation hereof through no
fault of Consultant. Consultant agrees that his consulting fee hereunder and the
benefits he will realize under the Asset Purchase Agreement include sufficient
consideration for the foregoing covenants.

      6. Return of Materials. Upon the termination or expiration of Consultant's
consulting relationship with UroMed, Consultant shall immediately deliver to the
President of UroMed all files, notes, lists, rolodex cards, credit cards,
computer disks, recordings, print-outs, and drawings (including, without
limitation, any materials reflecting or containing Proprietary Information) that
are under the control or in the possession of Consultant and relate to the
operation and business of UroMed. Consultant shall not be entitled to retain any
duplicates of the foregoing.

      7.    Non-Competition; Assignment of Restricted Inventions.

            (a) Consultant agrees that for a period of three (3) years after the
Closing Date (as that term is defined in the Asset Purchase Agreement),
Consultant will not directly (as owner, partner, principal in any entity or
otherwise) or indirectly (as an employee, agent, contractor, advisor,
beneficiary or otherwise) engage in, or participate in any entity that engages
in, any activity involving the development, manufacturing or marketing of any
product, product concept, service or service concept in the area of non-surgical
male and female incontinence technology that is adhesive in nature or otherwise
contains an external portion that a user can manipulate (including without
limitation the Product, as that term is defined in the Asset Purchase
Agreement). Consultant acknowledges that UroMed's business is global in nature
and therefore agrees that the foregoing restrictions apply both within and
outside the United States.

<PAGE>
                                      -4-

            (b) Until the expiration of the period referred to in subsection (a)
above, Consultant shall provide UroMed with written notice (i) of any change of
Consultant's residential address; and (ii) stating the name, address and nature
of each subsequent employment or consulting activity. Any such notice of
subsequent employment or business activity shall include Consultant's
certification that such employment or consulting activity does not violate the
provisions of this agreement.

            (c) Until the expiration of the period referred to in subsection (a)
above, Consultant agrees not to seek to persuade any UroMed employee,
consultant, director, officer or advisory board member to discontinue
association with UroMed or become involved directly or indirectly in any
endeavor that Consultant is restricted from engaging in under subsection (a)
above.

            (d) Consultant agrees that he will promptly notify UroMed in writing
of any technology, invention, discovery, concept, and/or idea, whether or not
patentable copyrightable, developed by Consultant prior to the expiration of the
period referred to in subsection (a) above that relates or may relate to any
endeavor that Consultant is restricted from engaging in under subsection (a)
above ("Restricted Inventions"). UroMed is hereby irrevocably granted the option
to take an unconditional, exclusive, irrevocable, royalty-free assignment of
such Restricted Invention(s) upon written notice mailed to Consultant within
thirty (30) days after UroMed's receipt of Consultant's initial notice. If
UroMed duly exercises such option, Consultant shall execute and deliver such
instruments of assignment therefor as UroMed may deem necessary or advisable
including, without limitations, applications for patent and/or copyright
registration.

            (e) Consultant represents and warrants for UroMed's reliance that
the foregoing covenants in subsections (a) through (d) above will not unduly
impair Consultant's ability to obtain gainful employment or consulting
relationships in Consultant's field during or subsequent to Consultant's
consulting relationship with UroMed. Consultant further agrees that his
consulting fee hereunder and the benefits he will realize under the Asset
Purchase Agreement include sufficient consideration for the restrictions imposed
by the foregoing covenants.

      8. Consultant Representations. Consultant represents and warrants for
UroMed's reliance that (i) this agreement does not conflict with any other
agreement, promise and/or commitment undertaken by Consultant that could
prohibit or impair the performance of Consultant's obligations hereunder; (ii)
Consultant has not and shall not disclose to UroMed, its officers, directors,
employees or agents any proprietary information of another individual or company
prohibiting such disclosure; (iii) Consultant's compliance with the
confidentiality, non-competition and other provisions of this agreement will not
materially impair Consultant's ability to earn a living outside of UroMed in his
field; and (iv) all information on Consultant's education, past work experience
and other qualifications presented to UroMed are accurate, complete and not
misleading.

      9. Indemnification. UroMed agrees to indemnify and hold Consultant
harmless for any losses of Consultant caused by any injury resulting from the
use of the Acquired Assets (as defined in the Asset Purchase Agreement) or any
products or inventions or improvements thereto arising from this consulting
relationship designed by Consultant.

      10.   Miscellaneous.

            (a) Each of the Consultant and UroMed represents that he or it has
not used any employment counselor or other person who would be entitled to any
compensation for arranging or obtaining the consulting relationship hereby
obtained.

<PAGE>
                                      -5-

            (b) All notices and other communications hereunder shall be in
writing or by written telecommunication, and shall be deemed to have been duly
given if delivered personally or if mailed by certified mail, return receipt
requested, postage prepaid, or if sent by nationally recognized reputable
overnight courier (e.g., FedEx), or by facsimile confirmed by one of the other
methods of giving notice hereunder, to the relevant address set forth in the
preamble hereto, or to such other address as the recipient of such notice or
communication shall have specified to the other party hereto in accordance with
this Section 9(b). All such notices shall be deemed given upon receipt if
delivered personally or by facsimile confirmed as provided above, or five (5)
days after mailing if mailed by certified mail, or one (1) day after mailing if
sent by nationally recognized reputable overnight courier.

            (c) Consultant agrees that any breach of Section 4 through 7,
inclusive, will result in irreparable damage to UroMed and therefore consents
that in addition to any other remedies it may have (including without limitation
recovery of provable damages and reasonable attorneys' fees) UroMed will be
entitled to enjoin any such breach in any court of competent jurisdiction.

            (d) The parties acknowledge that this agreement constitutes the
complete agreement of the parties concerning the subject matter hereof and
concerning the Consultant's consulting relationship with UroMed and all offer
letters, negotiations and other agreements are superseded and extinguished
hereby. No modification or amendment hereof shall be valid or enforceable unless
it is in writing and executed and delivered by the parties. The waiver by any
party of a breach of any provision of this agreement shall not operate or be
construed as a waiver of any subsequent breach.

            (e) If any provision in this agreement is found unenforceable, it
shall not affect any other provisions hereof. If any provision in this agreement
is determined to be unenforceable, it shall be construed by limiting it so as to
be enforceable to the fullest extent compatible with applicable law and so as to
give effect to the fullest extent possible the agreement of the parties as
evidenced by this agreement.

            (f) This agreement shall bind and inure to the benefit of the
parties and any successor of UroMed by reorganization, merger, consolidation,

Needham, Massachusetts  02194

      Re:   The Advanced Surgical Intervention, Inc. Liquidating Trust -
            June 20, 1994

Ladies and Gentlemen:

      We have acted as counsel to the Advanced Surgical Intervention, Inc.
Liquidating Trust - June 20, 1994, a trust organized under the laws of the State
of California (the "Trust"), and those persons named as Indemnifying
Beneficiaries (the "Beneficiaries") on the signature pages to that certain Asset
Purchase Agreement dated as of May 9, 1996 (the "Asset Purchase Agreement")
between the Trust and the Beneficiaries, on the one hand, and UroMed
Corporation, a Massachusetts corporation (the "Buyer"), on the other hand, in
connection with the transactions contemplated by the Asset Purchase Agreement.
This opinion is being delivered pursuant to Section 4.2 of the Asset Purchase
Agreement. Unless specifically defined herein or the context requires otherwise,
capitalized terms used herein shall have the meanings ascribed to them in the
Asset Purchase Agreement.

      In connection with the preparation of this opinion, we have examined the
documents listed below (the "Acquisition Documents"):

      A.    The Asset Purchase Agreement;

      B.    The Bill of Sale executed by the Trust, dated May 9, 1996;

      C.    The Patent Assignment executed by the Trust, dated May 9, 1996;

      D.    The Assumption Agreement between the Trust and the Buyer, dated
            May 9, 1996; and

      E.    The Registration Rights Agreement, dated May 9, 1996  among the
            Trust, the Buyer and the Beneficiaries named on the signature pages
            thereto.

<PAGE>
                                      -2-

      In addition, we have examined such other documents and considered such
questions of law as we have deemed necessary or appropriate. We have assumed
that, except for the Acquisition Documents and the documents required or
contemplated thereby, there are no other documents or agreements among the
Trust, the Beneficiaries and the Buyer which would expand or otherwise modify
the respective rights and obligations of the Trust, the Beneficiaries and the
Buyer as set forth in the Acquisition Documents, and the documents required or
contemplated thereby.

      We have assumed the authenticity of all documents submitted to us as
originals, the conformity with originals of all documents submitted to us as
copies and the genuineness of all signatures. We have also assumed that the
Trust and the Beneficiaries have received the agreed-to consideration due and
payable at Closing, and that, with respect to all parties to agreements or
instruments relevant hereto other than the Trust and the Beneficiaries, such
parties had the requisite power and authority to execute, deliver and perform
such agreements or instruments, that such agreements or instruments have been
duly authorized by all requisite action, executed and delivered by such parties
and that such agreements or instruments are the valid, binding and enforceable
obligations of such parties.

      As to questions of fact material to our opinions, we have relied upon the
representations of each party made in the Acquisition Documents and the other
documents and certificates delivered in connection therewith, certificates of
the Trustee and certificates and advices of public officials.

      Whenever a statement herein is qualified by "known to us," "to our actual
knowledge," or similar phrase, it is intended to indicate that, during the
course of our representation of the Trust and the Beneficiaries, no information
that would give us actual knowledge of the inaccuracy of such statement has come
to the attention of those attorneys in this form who have rendered legal
services to the Trust or the Beneficiaries. However, except as otherwise
expressly indicated, we have not undertaken any independent investigation to
determine the accuracy of such statement, and any limited inquiry undertaken by
us during the preparation of this opinion letter should not be regarded as such
an investigation; no inference as to our knowledge of any matters bearing on the
accuracy of any such statement should be drawn from the fact of our
representation of the Trust and the Beneficiaries.

      Based upon the foregoing, and subject to the assumptions, exceptions,
qualifications and limitations set forth herein, we are of the opinion that:

      1. The Trust is a liquidating trust duly organized under the laws of the
State of California with full power and authority to enter into the Acquisition
Documents to which it is a party and to consummate the transactions contemplated
thereby.

      2. The Acquisition Documents have been duly authorized by all necessary
actions on the part of the Trustees and beneficiaries of the Trust. The
Acquisition Documents to which the 

<PAGE>
                                      -3-

Beneficiaries are parties have been authorized by all necessary corporate or
other actions on behalf of such Beneficiaries.

      3. When executed and delivered by the Trustees of the Trust and the
Beneficiaries, respectively, the Acquisition Documents will be legal, valid and
binding obligations of the Trust and the Beneficiaries enforceable against them
in accordance with their terms, except as the enforceability thereof may be
subject to or limited by (a) bankruptcy, insolvency, reorganization,
arrangement, moratorium, or other similar laws relating to or affecting rights
of creditors and (b) general equitable principles, regardless of whether the
issue of enforceability is considered in a proceeding in equity or at law.

      4. Neither the execution and delivery of the Acquisition Documents by the
Trust nor the consummation by the Trust of the transactions contemplated thereby
(a) will constitute a violation of, or be in conflict with, or constitute or
create a default under, or result in the creation or imposition of any
encumbrance upon an property of the Trust (including, without limitation, any of
the Acquired Assets) pursuant to, (i) the Liquidating Trust Agreement, or (ii)
to our actual knowledge, any judgment, order, decree, stipulation, injunction,
charge or other restriction of any court or other tribunal to which either the
Trust or any of its properties is subject, or (b) is prohibited by, or subjects
the Trust to a fine, penalty or other similar sanction, under any (i) statute or
regulation of the State of California, or (ii) any federal statute or
regulation.

      5. No consent, approval or authorization of, or designation, declaration
or filing with, any governmental authority is required in connection with the
valid execution, delivery and performance by the Trust or any Beneficiary of the
Acquisition Documents.

      6. Except as disclosed in the Asset Purchase Agreement or the exhibits and
schedules delivered in connection therewith, there is, to our actual knowledge,
no action, suit or proceeding by any governmental agency pending against the
Trust or its properties or any Beneficiary in any court or before any
governmental authority or agency, or arbitration board or tribunal which seeks
to restrain, enjoin, prevent the consummation of, or otherwise challenge the
Acquisition Documents or any of the transactions contemplated thereby.

      The foregoing opinion are subject to the following:

      We expressly do not comment upon or render any opinion with respect to any
documents referenced in the Asset Purchase Agreement, except for the other
Acquisition Documents or the Liquidating Trust Agreement.

      We call your attention to the fact that certain of the Acquisition
Documents state that they are governed by Massachusetts law and that we are not
rendering any opinion with respect to Massachusetts law. We have not examined
the question of what law would govern the interpretation or enforcement of the
Acquisition Documents and our opinion is based on the assumption that the
internal laws of the State of California and federal law would govern the
provisions of the Agreement and the transactions contemplated thereby. We
express no opinion regarding the enforceability of the choice of law provisions
of the Acquisition Documents.

<PAGE>
                                      -4-

      We express no opinion with respect to:

            (i)  the enforceability of the non-competition  provisions of
      Section 8.1 of the Asset Purchase Agreement;

            (ii) matters involving the federal Food, Drug and Cosmetic Act, as
      amended, or the rules and regulations thereunder, or California laws and
      regulations regarding drugs and medical devices; or

            (iii) patent, trademark and related matters.

      With respect to our opinion in paragraph 5 above, we have assumed that the
Buyer was not required to make a filing under the Hart-Scott-Rodino Antitrust
Improvements act of 1976. Except with respect to any filings required by the
Trust under such act, we express no opinion on antitrust matters.

      We are members of the Bar of the State of California and, accordingly, do
not purport to be experts on or to be qualified to express any opinion herein
concerning, nor do we express any opinion herein concerning, any laws other than
the laws of the State of California and federal law.

      The foregoing opinions are being furnished to you solely for your benefit
and may not be relied upon by any other person without our prior written
consent. This opinion is as of this date, and we expressly decline any
undertaking to advise you of any maters arising subsequent to the date hereof
which would cause us to amend any portion of the foregoing in whole or in part.

                                Very truly yours,

      Re:   The Advanced Surgical Intervention, Inc. Liquidating Trust -
            June 20, 1994

Ladies and Gentlemen:

      We are patent counsel to the Advanced Surgical Intervention, Inc.
Liquidating Trust - June 20, 1994, a trust organized under the laws of the State
of California (the "Seller"), and to Advanced Surgical Intervention, Inc., a
California corporation ("ASI"). This opinion is being furnished to you pursuant
to Section 4.2(g) of the Asset Purchase Agreement dated May _____, 1996 (the
"Agreement") between UroMed Corporation, a Massachusetts corporation ("UroMed"),
and the Seller; relating to the sale to UroMed by the Seller of all of the
assets of the Seller and ASI relating to male and female incontinence. Unless
otherwise defined in this letter, the definition of the capitalized terms used
in this opinion shall be the same as those in the Agreement.

      We are familiar with the technology of the Seller and ASI related to male
and female incontinence including without limitation the technology relating to
the so-called "MiniGuard" product, and we have filed and prosecuted the U.S. and
foreign patent applications and obtained the U.S. and foreign patents identified
on Schedule A to this opinion (the "Patent Rights") relating to male and female
incontinence.

      We are of the opinion that:

      (a) The Seller has full and clear record title to all of the Patent
Rights.

      (b) To the best of our knowledge, neither the Seller nor ASI has rights in
any U.S. or foreign patents or patent applications relating to male and female
incontinence other than the Patent Rights.

      (c) To the best of our knowledge, none of the U.S. or foreign patents in
the Patent Rights is unenforceable or invalid. We are not aware of any patent,
trade secret, or other 


<PAGE>
                                      -2-

intellectual property rights of others that are or would be infringed by
practicing the male or female incontinence technology described in the Patent
Rights.

      (d) We are not aware of anyone who has asserted that he or she is an
inventor of the Patent Rights and who has not been named as such an inventor in,
or of any third party who has asserted that he or she has an ownership interest
in any of the Patent Rights or other Intellectual Property of the Seller or ASI.

      (e) To the best of our knowledge, there are no pending legal or
governmental proceedings or litigation relating to the Patent Rights, other than
U.S. and foreign patent office review of pending patent applications, including
appeal proceedings, and, to the best of our knowledge, no such proceedings are
threatened or contemplated by governmental authorities or others.

      (f) We are not aware of any contracts or other documents material to the
Patent Rights or other Intellectual Property of the Seller or ASI other than
those identified in the Agreement or in the schedules thereof. In particular, to
the best of our knowledge, the Patent Rights are not subject to any license
rights of any third party.

                                Very truly yours,

Ladies and Gentlemen:

      We have acted as special counsel to UroMed Corporation, a Massachusetts
corporation (the "Company"), in connection with its purchase of the Acquired
Assets under and as defined in the Asset Purchase Agreement, dated as of May 9,
1996 (the "Asset Purchase Agreement") by and between the Company, on the one
hand, and the ASI Liquidating Trust (the "Seller"), and the Indemnifying
Beneficiaries named on Annex A thereto, on the other hand. This opinion is being
furnished to you pursuant to Section 4.2 of the Asset Purchase Agreement.
Capitalized terms used herein without definition shall have the meanings
assigned to them in the Asset Purchase Agreement.

      In connection with the rendering of this opinion, we have reviewed
originals or copies of each of the Asset Purchase Agreement, dated May 9, 1996,
delivered by the Company to the Seller, and the Registration Rights Agreement,
dated May 9, 1996, by and among the Company, the Seller and the Beneficiaries
named on the signature pages thereto (collectively, the "Acquisition
Documents"), copies, certified or otherwise identified to our satisfaction, of
the charter documents and by-laws of the Company, resolutions of the Board of
Directors of the Company authorizing the transactions contemplated by the Asset
Purchase Agreement, the certificates of public officials attached hereto as
Exhibit 1, and such other documents as we have deemed necessary or appropriate
for purposes of this opinion.

      As to all matters of fact (including, without limitation, factual
conclusions and characterizations and descriptions of purpose, intention or
other state of mind), we have relied entirely upon the written representations
made to us by officers of the Company and attached hereto as Exhibit 2 and the
representations set forth in Sections 5 and 6 of the Asset Purchase 


<PAGE>
                                      -2-

Agreement have assumed, without independent inquiry, the accuracy of such
representations. As to any opinion below relating to the existence,
qualification or standing of the Company in any jurisdiction, our opinion relies
entirely on and is limited by those certificates attached hereto as Exhibit 1.

      We have assumed the genuineness of all signatures, the conformity to the
originals of all documents reviewed by us as copies, the authenticity and
completeness of all original documents reviewed by us in original or copy form
and the legal competence of each individual executing any document.

      When an opinion set forth below is given to the best of our knowledge, or
to our knowledge, or with reference to matters of which we are aware or which
are known to us, or with another similar qualification, the relevant knowledge
or awareness is limited to the actual knowledge or awareness of the individual
lawyers in the firm who have participated directly in the specific transactions
to which this opinion relates and without any special or additional
investigation or search of court dockets undertaken for the purposes of this
opinion.

      Each opinion set forth below relating to the enforceability of any
agreement or instrument against the Company is subject to the following general
qualifications:

            (i) as to any instrument or agreement delivered by the Company we
      assume that the Company has received the agreed-to consideration therefor;

      With respect to our opinion in paragraphs 4 and 5 below, we have assumed
that the Seller was not required to make a filing under the Hart-Scott-Rodino

by the Company under such Act, we express no opinion on antitrust matters.

      Subject to the limitations set forth below, we have made such examination

limited solely to the internal substantive laws of The Commonwealth of
Massachusetts as applied by courts located in Massachusetts, and the Federal
laws of the United States of America (except with respect to matters involving
the Federal Food, Drug and Cosmetic Act, as amended, or the rules and
regulations thereunder, any matter relating to the United States Food and Drug
Administration, or any matter relating to patents, patent law, patent
applications or related matters), to the extent that the same may apply to or
govern such transactions. No opinion is given herein as to the choice of law or,
except as set forth above, the internal substantive rules of law that any
tribunal may apply to the transactions referred to herein.

      We understand that all of the foregoing assumptions, limitations and

standing under the laws of the Commonwealth of Massachusetts.

      2. The Acquisition Documents have been duly authorized by all necessary
corporate action of the Board of Directors and shareholders of the Company and

      3. The shares of UroMed Common Stock to be issued to the Seller pursuant
to the terms of the Asset Purchase Agreement have been duly authorized and, when
such shares are issued and delivered against payment therefor as provided in the
Asset Purchase Agreement, will be validly issued, fully paid and non-assessable.

      4. Neither the execution and delivery of the Acquisition Documents by the
Company nor the consummation by the Company of the transactions contemplated
thereby will constitute a violation of, or be in conflict with, or constitute or
create a default under, or result in the creation or imposition of any
encumbrance upon any property of the Company (including, without limitation, any
of the Acquired Assets) pursuant to, (a) the restated articles of organization
or By-laws of the Company, or (b) any provision of the laws or regulations of
Massachusetts or of Federal law or regulations, or (c) to the best of our

      6. To the best of our knowledge, there is no litigation by any
governmental agency pending against the Company which questions the legality,
validity or propriety of the Acquisition Documents or of any action taken or to
be taken by the Company pursuant to the Acquisition Documents.

                     UROMED CORPORATION ANNOUNCES ACQUISITION OF
                   MINIGUARD(TM) PATCH PRODUCT AND TECHNOLOGY

A Complementary Product to the Reliance(R) Insert, the Miniguard Patch Expands
           UroMed's Market Opportunities, Strengthens Patent Portfolio

      NEEDHAM, MA, May 10, 1996 -- UroMed Corporation (NASDAQ:URMD) today
announced that it has acquired from the Advanced Surgical Intervention (ASI)
Liquidating Trust all assets relating to the Miniguard Patch, a U.S. Food and
Drug Administration (FDA) cleared product, and other ASI-developed incontinence
technology. The Miniguard product is a small, disposable, prescription adhesive
patch placed externally against the urethral opening to help block leakage in
women with mild to moderate stress incontinence. Additionally, the acquisition
gives UroMed fundamental patents which the company believes broadly cover
incontinence barrier products that use adhesive technology.
      UroMed purchased the Miniguard Patch and its related technology for $30
million, consisting of $7 million in cash and $23 million in common stock. The
transaction will be acounted for as a purchased research and development charge,
which UroMed expects to take in the second quarter of 1996.
      Commenting on the acquisition, UroMed's chairman of the board and chief
executive officer John G. Simon said, "The Miniguard Patch is a complementary
product that furthers UroMed's leadership position in creating and marketing
effective options for improving the lifestyles of women with urinary
incontinence. Similar to pads and tampons in the case of menstruation, the
Miniguard and Reliance Insert devices form an exciting

combination, allowing UroMed to cover a broad range of needs for women suffering
from varying degrees of incontinence."
     "The Miniguard Patch was designed to provide a new option for women with
stress incontinence that is discreet, external, easy to apply, and comfortable,"
said Dr. Robert F. Rosenbluth, former chief executive officer of ASI and
co-inventor of the Miniguard Patch. "In a clinical study conducted at 12 centers
nationwide with 356 incontinent women followed for more than 1,000 patient
months of usage, patient dryness, quality of life, and ability to conduct
various daily activities were significantly improved through wearing the
Miniguard Patch. More than 100,000 devices were used by these women during the
study. In a patient survey, 46 percent of patients reported being completely dry
with the product."
      John Simon continued, "We are pleased that the FDA cleared the Miniguard
Patch 510(k) application for marketing in the United States on May 8, 1996. If
we successfully scale up manufacturing for commercial production of the
Miniguard Patch, and if we are successful with our market launch efforts, the
product should start to make a contribution to UroMed's growth as soon as late
1997. We believe that the Miniguard Patch is a very significant product that
fits with our stringent acquisition criteria."
      UroMed Corporation was founded to develop, manufacture and market products
for the management of urological and gynecological disorders. The company's
first two products, the Reliance Urinary Control Insert and the Miniguard Patch,
are intended for the management of certain types of female urinary incontinence.
According to company estimates, urinary incontinence (UI), the loss of bladder
control resulting in the involuntary leakage of urine, afflicts approximately 26
million women in the United States, Japan and selected countries in Europe.
UroMed's Reliance Insert and Miniguard Patch are designed for an estimated
target market in excess of six million of these women worldwide who suffer from
certain types of UI and seek to maintain their active lifestyles. UroMed has
designated the Reliance Insert in order to provide the appropriate UI patient,
who now typically wears diapers or pads, with similar lifestyle benefits to
those conferred by a tampon in the case of menstruation. UroMed's Miniguard
Patch is designed for a broader group of mild to moderate UI patients.
