         3.4      REPORTS, FINANCIAL STATEMENTS AND OTHER DOCUMENTS

                  Phoenix has been provided with complete and correct copies of
         audited financial statements of Anawa and its Subsidiaries for the
         years ended December 31, 1994, 1995, 1996 and 1997, copies of which are
         attached hereto as Schedule 3.4A.

                  The financial statements of Anawa and the Subsidiaries
         referred to above have been prepared in accordance with Swiss GAAP and
         all such financial statements fairly present the financial condition of
         Anawa and the Subsidiaries at the dates thereof and the results of
         their operations for the periods covered thereby. Other than as set
         forth in Schedule 3.5, neither Anawa nor any of the Subsidiaries has
         material liabilities, contingent or otherwise, which are not referred
         to in the financial statements.

                  The financial statements for the year ended December 31, 1994,
         1995, 1996 and 1997, copies of which are attached hereto as Schedule
         3.4A have been properly approved by the annual general meetings of
         shareholders of the relevant entities in due form without reservation.

                  For purposes of financial presentation, Anawa recognizes net
         revenue from its contracts on a percentage of completion basis as work
         is performed. The percentage of completion, and consequently the
         revenue to be recorded, of each individual contract is determined
         through detailed analysis and discussion between all appropriate
         operational and financial department management. Although Anawa does
         not require collateral for unpaid balances, credit losses have
         consistently been within Management's expectations. Certain contracts
         contain provisions for price adjustment for cost overruns. Such
         adjusted amounts are included in service revenue when realization is
         assured and the amounts can be reasonably 




                                     - 11 -


         determined. In the period in which it is determined that a loss will
         result from the performance of a contract, the entire amount of the
         estimated ultimate loss is charged against income.

                  Since January 1, 1998, the business of Anawa and the
         Subsidiaries has been operated in the customary fashion and no revenues
         that would have been earned by Anawa or the Subsidiaries have been
         earned by any Person who is an Affiliate of any of the Vendors.

                  Notwithstanding anything else in this Agreement, including,
         without limitation, the provisions of this Section 3.4, the Vendors
         make no representation or warranty of any kind whatsoever with respect
         to future business, financial performance or future profitability of
         Anawa.

         3.5      OFF BALANCE SHEET OBLIGATIONS

                  Schedule 3.5 contains a complete list of the off-balance sheet
         obligations of Anawa and the Subsidiaries, including all guarantees and

         third parties.

                           (other than Compensation of its directors, officers
                           and employees in amounts in effect prior to January
                           1, 1998 or for bonuses accrued in accordance with
                           normal practice prior to January 1, 1998) to any of

                  3.6.3    INVENTORY AND WORK-IN-PROGRESS. The value of
                           inventory and work-in-progress reflected in the
                           financial statements of Anawa and the Subsidiaries
                           has been established in accordance with Swiss GAAP
                           and there has been no material change in the period
                           subsequent to December 31, 1997, other than in the
                           ordinary and usual courses of business.

                  3.6.4    REVENUES. The business of Anawa and the Subsidiaries
                           has been operated in the customary fashion and no
                           revenues that would have been earned by Anawa or the
                           Subsidiaries have been earned by any Person which is
                           an Affiliate of any of the Vendors.

                           risks to which each of Anawa and the Subsidiaries and
                           their respective property and assets are normally
                           exposed in the operation of their respective
                           businesses, including without limitation professional
                           liability. All policies, the absence of which,
                           individually or in the aggregate, would result in a
                           Material Adverse Effect, are in full force and
                           effect. There are no outstanding unpaid premiums
                           except in the ordinary course of business, and
                           neither Anawa nor any Subsidiary has received any
                           notice of cancellation or non-renewal of any such
                           policy. Neither Anawa nor any Subsidiary is aware of
                           any risks, situations, occurrences or other matters
                           which have been disclosed, or should have been
                           disclosed, to insurance carriers or brokers in
                           connection with any application for such insurance as
                           a result of which an insurance carrier would have a
                           right to cancel the corresponding insurance policy or
                           deny coverage with respect to any rights under any
                           such policies. There exists no event of default or
                           event, occurrence, condition or act (including the
                           transactions contemplated by this Agreement) which,
                           with the giving of notice, the lapse of time or the
                           happening of any further event or condition, would
                           become a default or occasion a material premium
                           increase under any such policy or give rise to, and
                           neither Anawa nor any Subsidiary has any anticipation
                           of, any termination or cancellation thereof or
                           material premium increase therefor.

                  3.8.5    DISPUTE. Neither Anawa nor any of the Subsidiaries
                           has received any notice from any supplier, vendor,
                           contractor, customer or client with which Anawa or
                           such Subsidiary has conducted business during the
                           one-year period ending on the date of this Agreement
                           confirming such Person's intention to reduce the
                           volume under, terminate or otherwise alter any
                           Contractual Obligation with Anawa or any Subsidiary,
                           the effect of which, individually or in the
                           aggregate, would result in a Material Adverse Effect.

         3.9      OPERATIONS IN CONFORMITY WITH LAW, ETC.

                  The operations of Anawa and the Subsidiaries as now conducted,
         and their properties, assets, equipments, buildings, immoveables and
         leased or occupied properties, are not, and have not been, in violation
         of, nor is Anawa or any of the Subsidiaries in default and no event has
         occurred which with notice or lapse of time or both would constitute a
         default under, any applicable Legal Requirements including, in
         particular, any applicable Environmental Laws or Legal Requirements
         regarding clinical research and experimentation on animals, except for
         such violations and defaults as do not and shall not, in the aggregate,
         have a Material Adverse Effect. Neither Anawa nor any of the
         Subsidiaries has received notice of any such violation or default and
         there are no basis on which the operations of Anawa or any of the
         Subsidiaries, when conducted as currently proposed to be conducted
         after the Completion Date, would be held so as to violate or to give
         rise to any such violation or default. Anawa and the Subsidiaries have
         all franchises, licenses, permits, certificates, authorizations,
         registrations or other authority presently necessary for the conduct of
         their business as now conducted, except for franchises, licences,
         permits, certificates, authorizations, registrations or other
         authority, the absence of which, individually or in the aggregate, does
         not and shall not result in a Material Adverse Effect. Based on the
         facts presently known to the Vendors and Management, all future
         expenditures on the part of Anawa and the Subsidiaries required to meet
         the provisions of any presently existing applicable Legal Requirements
         (including Legal Requirements relating to employment practices or to
         occupational or health standards or to environmental considerations)
         shall not, in the aggregate, have a Material Adverse Effect. Anawa and
         the Subsidiaries have complied and are in compliance with applicable
         competition regulations and have never infringed fair competition in
         the markets where they operate, either with or towards third companies
         or between themselves. Anawa and the Subsidiaries do not hold
         separately or together a dominant position on the markets involved and
         their market share and net aggregate turnover do not meet the European
         and Swiss thresholds which authorizes European or domestic competition
         authorities to control the operation and impede the completion of the
         transaction contemplated hereby.

         3.10     INTELLECTUAL PROPERTY

                  Schedule 3.10 contains a list of all the trade-marks, trade
         names and patents used by any of Anawa or the Subsidiaries
         (collectively "Used Intellectual Property"). The entity indicated in
         said Schedule as owner of Used Intellectual Property is the registered
         and beneficial owner of such Used Intellectual Property or the
         registration thereof, if applicable, (except as set forth in Schedule
         3.10), with good and marketable title, unencumbered (except for
         Permitted Liens), and with full right to sell, assign or otherwise
         transfer or license to others and subject to no pending challenge,
         refutation, expiry or termination other than as set forth in Schedule
         3.10. To the best of Vendors' knowledge, other than as set forth in
         Schedule 3.10, none of Anawa or the Subsidiaries uses any intellectual
         property not owned by it, other than software purchased "off the
         shelf", all of which each entity using said property has the right to
         use (collectively "Licenced Intellectual Property"). (Used Intellectual
         Property and Licensed Intellectual Property are sometimes hereinafter
         referred to collectively as "Intellectual Property"). None of Anawa or
         the Subsidiaries is required to pay royalties, fees or other
         consideration to any other person with respect to the use of any of the
         Intellectual Property or in connection with the conduct of its business
         or otherwise. To the best of Vendors' knowledge, none of Anawa or the
         Subsidiaries has infringed the intellectual or industrial property
         rights of any other person, nor has any of them used any intellectual
         or industrial property (including, without limitation, trade-marks,
         trade names, patents, models, designs and copyrights) which it does not
         own or have the right to use other than as set forth in Schedule 3.10.
         There are no outstanding claims asserted against any of Anawa or the
         Subsidiaries alleging the infringement or




                                     - 15 -


         the misappropriation by any of them of any intellectual or industrial
         property. None of Anawa or the Subsidiaries has granted any licences or
         sub-licences to third parties with respect to any of the Intellectual
         Property other than as set forth in Schedule 3.10 and neither the
         Vendors nor Management has any knowledge of any infringement or
         misappropriation by any other Person of any of the Intellectual
         Property. Neither the execution nor delivery of this Agreement will
         constitute a breach of or a default under any agreement relating to the
         Intellectual Property.

         3.11     ENVIRONMENTAL MATTERS

                  3.11.1   Anawa and the Subsidiaries, their employees, agents,
                           shareholders, directors and officers (acting in their
                           capacity of employees, agents, shareholders,
                           directors or officers of Anawa or of one of the
                           Subsidiaries) have never been declared guilty of
                           committing an offence for a violation of
                           Environmental Laws and have never been fined for such
                           an offence or have otherwise settled such a
                           prosecution in connection with the activities of
                           Anawa and the Subsidiaries;

                  3.11.2   There are no contaminants, waste or pollutants of any
                           kind whatsoever in, on or under the equipment,
                           buildings, immoveables or properties owned, leased or
                           occupied by Anawa or any of the Subsidiaries and
                           caused by Anawa, the Subsidiaries or their employees,
                           agents, shareholders, directors or officers (acting
                           in their capacity of employees, agents, shareholders,
                           directors or officers of Anawa or one of the
                           Subsidiaries), the presence of which constitutes a
                           violation of applicable Environmental Laws and the
                           presence of which, individually or in the aggregate,
                           constitutes a Material Adverse Effect;

                  3.11.3   Neither Anawa nor any of the Subsidiaries has
                           received any written notice or request for
                           information in the context of any national,
                           supra-national, provincial, regional, local or
                           municipal environmental investigation or inspection;

                  3.11.4   There are no PCBs, asbestos or urea formaldehyde
                           insolation in, on or under the equipment, buildings,
                           immoveables or properties owned, leased or occupied
                           by Anawa or the Subsidiaries;

                  3.11.5   There is no action, suit or proceeding pending in
                           relation to environmental matters against Anawa or
                           the Subsidiaries, its employees, agents,
                           shareholders, directors and officers (acting in their
                           capacity of employees, agents, shareholders,
                           directors or officers of Anawa or of one of the
                           Subsidiaries), or involving Anawa or the Subsidiaries
                           or its assets, before any judicial body, tribunal,
                           commission, agency or other governmental entity, and
                           to the Vendors' knowledge and to the knowledge of
                           Management, there is no threat of, or event or fact
                           based on which, such action, suit or proceeding may
                           be instituted;

                  3.11.6   To the knowledge of Management and the Vendors, Anawa
                           and the Subsidiaries are in compliance with all
                           applicable Environmental Laws.

         3.12     LABOUR AND EMPLOYMENT MATTERS

                  3.12.1   Without limiting the generality of Section 3.9, each
                           of Anawa and the Subsidiaries has complied with all
                           applicable laws relating to the employment of labour,
                           including provisions thereof relating to wages, hours
                           and collective bargaining rights.

                  3.12.2   There is no collective agreement by which Anawa or
                           any of the Subsidiaries is bound which relates to the
                           employees of Anawa or the Subsidiaries. To the best
                           knowledge of the Vendors and to the knowledge of
                           Management, there are no threatened or pending
                           attempts to organize or establish any labour union or
                           employee association in connection with the business
                           of Anawa or any of the Subsidiaries. To the best
                           knowledge of the Vendors and to the best knowledge of
                           Management, there is no pending or threatened labour
                           dispute, grievance, strike, or work stoppage
                           materially affecting the business of any of Anawa or
                           any of the Subsidiaries. Neither Anawa nor any of the

                           employment agreement, contract, arrangement,
                           management contract or service contract affecting
                           employees other than as set forth in Schedule 3.8.1,
                           nor are any such contracts, agreements, arrangements,
                           management contracts or service contracts being
                           currently negotiated or proposed other than in the
                           ordinary course of business.

                  3.12.3   There exist no retirement plans, profit sharing,
                           option or incentive plans, or other employee benefit
                           plans for employees of Anawa or any of the
                           Subsidiaries other than as set forth in Schedule
                           3.8.1 for which adequate arrangements have been made
                           since January 1, 1998 to set aside the requisite
                           amounts in the prescribed fashion, and neither Anawa
                           nor any of the Subsidiaries has promised or intends
                           to implement other such plans.

                  3.12.4   Neither Anawa nor any of the Subsidiaries has any
                           employee who cannot be dismissed without further
                           liability upon such notice period not exceeding what
                           it is required by the applicable Legal Requirement.

                  3.12.5   None of Anawa's or any of the Subsidiary's employees

         governmental charges upon Anawa and the Subsidiaries or upon any of
         their properties or income, including any tax in respect of value
         added, have been paid if and when due unless such payment is being
         contested in good faith and by appropriate proceedings and adequate
         reserves with respect thereto determined in accordance with applicable
         policies have been established by Anawa and the Subsidiaries. There is
         no tax revision threatened in writing against Anawa and any of the

         proceeding before, or investigation by, any foreign, national,
         supra-national or municipal, judicial, tax or customs tribunal or board

         pending or threatened (or does any basis exist therefor), against Anawa
         or the Subsidiaries or, to the Vendors' best knowledge or to the best
         knowledge of Management, any director or officer of Anawa or any of the
         Subsidiaries, which individually or in the aggregate could result in a
         Material Adverse Effect, or which seeks rescission of, seeks to enjoin
         the consummation of, or which questions the validity of, this Agreement
         or any of the transactions contemplated hereby. Neither Anawa nor the
         Subsidiaries has been charged, nor to the Vendors' knowledge or to the
         knowledge of Management, is it threatened to be charged, with
         infringement of any trademark, trade name, service mark, copyright,
         patent, patent right or other proprietary right of any Person.

         3.17     PRESS COVERAGE

                  Neither Anawa nor any of the Subsidiaries has been the object
         of any demonstrations, press campaigns or other attacks due to the

         constitute a default under any Contractual Obligation of Anawa or any
         of the Subsidiaries, (b) result in acceleration in the time for
         performance of any obligation of Anawa or the Subsidiaries under any
         such Contractual Obligation, (c) result in the creation of any Lien

5.       POOLING OF INTERESTS

         5.1      ACCOUNTING TREATMENT

                  Phoenix, Anawa and the Vendors intend and desire for the
         transactions contemplated by this Agreement to qualify for "pooling of
         interests" treatment for US GAAP purposes in accordance with Accounting
         Principles Board Opinion No. 16.

         5.2      SUCCESSFUL APPLICATION OF "POOLING OF INTERESTS"

                  The Vendors acknowledge that the successful application of
         "pooling of interests" accounting is one of the principal
         considerations in Phoenix purchasing the Shares. The Vendors represent
         that they have not taken any action listed in the letter attached
         hereto as Schedule 5.3 that would preclude the application of "pooling
         of interests" accounting nor will they agree or participate to any such
         action in the future.

         5.3      POOLING LETTER

                  On or prior to the Completion Date, Anawa shall cause to be
         executed and delivered to Phoenix a letter substantially in the form
         attached hereto as Schedule 5.3 dated the Completion Date from Anawa's
         management related to the compliance by Anawa with applicable "pooling
         of interests" criteria in form and substance reasonably satisfactory to
         Phoenix and its auditors.

         5.4      PLACEMENT AND STOCK TRANSFER RESTRICTIONS AND RELATED MATTERS

                  Each party to this Agreement agrees that from and after the
         date of this Agreement, such party shall not knowingly take any action,
         or knowingly fail to take any action, which action or failure is
         reasonably likely to disqualify the transactions contemplated by this
         Agreement from pooling of interests accounting treatment by Phoenix,
         and that such party shall take all reasonable actions necessary to
         cause the transactions contemplated by this Agreement to qualify as a
         pooling of interest, if such characterization shall be jeopardized by
         action taken by such party. Without limiting the foregoing, each Vendor
         who is a Pooling Affiliate of Anawa agrees that such Vendor shall not
         sell, transfer, pledge, or otherwise dispose of such Vendor's interests
         in or reduce such Vendor's risk relative to any of the Phoenix Shares
         until Phoenix shall have published financial results (including
         combined sales and net income) covering at least thirty (30) days of
         combined operations of Phoenix and Anawa after the Completion Date. No
         later than July 30, 1998, Phoenix shall prepare and publish such
         financial results for the first full month of operations following the
         Completion Date. Each of the Vendors and Anawa acknowledge and agree
         with Phoenix that none of the Vendors or Anawa is a party to any
         agreement or arrangement among themselves or with third parties
         regarding the transactions contemplated by this Agreement or the
         subject matter hereof.

8.       SPECIFIC CONTINGENCIES

         of the occurrence, in whole or in part, of any of the specific
         contingencies described below, each of which exists at the Completion
         Date and will only be finally resolved or determined at some time in
         the future. The provision for these contingencies is not made as an
         attempt to anticipate future events, but merely to provide for a
         reasonable period of time within which such contingencies may be
         resolved. Any indemnification pursuant to this Section shall be payable
         by all of the Vendors, pro rata to the number of common shares of
         Phoenix issuable to each of them pursuant to this Agreement.

                  In the event of the realization of any of the specific
         contingencies contemplated in this Section 8, the Vendors shall
         indemnify Phoenix by remitting to Phoenix for cancellation such number
         of Phoenix Shares as corresponds to the amount of indemnification owed
         (calculated on the basis of the Escrowed Share Price). Any obligation
         to remit common shares of Phoenix upon the occurrence of a specific
         contingency shall be satisfied by return of Escrowed Shares in
         accordance with the Escrow Agreement. In the event that there does not
         remain a sufficient number of Escrowed Shares or Proceeds (as defined
         in the Escrow Agreement) to satisfy an obligation under this Section,
         such shortfall always to be calculated on the basis of the Escrowed
         Share Price, the balance of such indemnification obligation shall be
         paid in cash. All dividends or other distributions received by a Vendor
         in respect of Phoenix Shares which are remitted to Phoenix in
         satisfaction of an indemnification obligation under this Section 8,
         shall also be repaid to Phoenix at the time of payment of
         indemnification.

         8.1 Any liability related to the cessation of employment of Fischer.
         The maximum amount payable in respect of this contingency is SFr220,000
         plus any interest due to the plaintiff(s) from the date of this
         Agreement to the final settlement of this specific contingency.
         Notwithstanding any other provision of this Agreement, the Vendors'
         indemnification obligation with respect to this contingency shall
         survive until any possible claims have been prescribed under applicable
         law.

         alliance (or similar matters) with Dr. Rondez AG. The maximum amount
         payable in respect of this contingency is SFr1,100,000 plus any
         interest due to the plaintiff(s) from the date of this Agreement to the
         final settlement of this specific contingency. Notwithstanding any
         other provision of this Agreement, the Vendors' indemnification
         obligation with respect to this contingency shall survive until any

                1.1.14  "VENDORS" means Vollenweider, Albers, Fischer, Innovent,
                        Hassler, Joller, Karabelnik and Wicki.

        1.2     Each capitalized term used in this Agreement but not defined
                herein as the meaning ascribed thereto in the Purchase
                Agreement.

        1.3     In the event of (i) any subdivision, consolidation or
                reclassification of the class of shares comprising the Escrowed
                Shares or (ii) any reorganization of the share capital of
                Phoenix affecting the Escrowed Shares or (iii) the amalgamation
                of Phoenix with any other company, the number of Escrowed Shares
                and Escrowed Share Price shall be adjusted, if required, so that
                none of the parties hereto shall be in a position less favorable
                to it than as provided in this Agreement as a result of any of
                the foregoing actions.

        1.4     For all purposes of this Agreement, the amount of any Claim in a
                currency other than Canadian dollars shall be converted to
                Canadian dollars at the exchange rate between Canadian and such
                currency shall be the "Spot Rate" of the alternate currency on
                the business day preceding the day as of which the conversion
                from one currency to the other is to be effected, as reported in
                the Financial Post of Canada on that day.

        1.5     In any calculation hereunder of the applicable number of
                Escrowed Shares results in fractional shares, the result shall
                be rounded up or down, as the case may be, to the nearest 




                                      -4-

                whole number and, if such result represents exactly one-half of
                a whole number, then such fraction shall be rounded up to the
                next whole number.

2.      ESTABLISHMENT OF ESCROW

        2.1     Phoenix hereby delivers in escrow to the Escrow Agent
                certificates representing an aggregate of 176,507 common shares
                of Phoenix registered in the name of the Escrow Agent, as escrow
                agent (the "Escrowed Shares"). The Vendors' interests in the
                Escrowed Shares are as set forth below:




                VENDOR                                            ESCROWED SHARES
                ------                                            ---------------
                                                                  
                Vollenweider                                      29,559
                Albers                                            27,653
                Fischer                                           14,844
                Innovent                                          30,595
                Hassler                                           2,059
                Joller                                            8,708
                Karabelnik                                        29,553
                Wicki                                             33,536



        2.2     The Escrow Agent hereby accepts delivery and acknowledges
                receipt of the Escrowed Shares and agrees to act as escrow agent
                and to hold, safeguard and release the Escrowed Shares in
                accordance with the provisions of this Agreement. The Escrowed
                Shares shall not be assigned, hypothecated, alienated, released
                from escrow, transferred within escrow or dealt with in any
                manner whatsoever except as provided in this Agreement.

        2.3     Notwithstanding the registration of the Escrowed Shares in the
                name of the Escrow Agent, the Vendors shall, subject to the
                provisions hereof, remain the owners thereof in the proportion
                contemplated by Section 2.1 hereof and be entitled to the
                exercise of all voting rights related thereto and to receive all
                dividends, income and other distributions in respect thereof
                (collectively, "Distributions"). In the event that any Escrowed
                Shares are remitted to Phoenix for cancellation pursuant to the
                provisions of Section 3 hereof, the Vendors shall repay to
                Phoenix any Distributions received in respect of such Escrowed
                Shares.

3.       INSTRUCTIONS TO ESCROW AGENT

        3.1     All communications made by the Vendors, including instructions
                to the Escrow Agent or Responses hereunder, shall be made by
                Wicki and Vollenweider jointly on behalf of the Vendors. All of
                the Vendors hereby authorize Wicki and Vollenweider jointly to
                duly represent them in accordance with all communications under
                this Agreement. Should the Vendors wish to withdraw this
                authorization and to designate new representatives they have 





                                      -5-


                to do so jointly and by notifying Phoenix and the Escrow Agent
                in accordance with Section 7 hereof.

        3.2     At any time while the Escrowed Shares are held by the Escrow
                Agent, a Non-Affiliate may instruct the Escrow Agent in writing
                to sell all or part of such Non-Affiliate's portion of the
                Escrowed Shares. Upon receipt of such written instruction, the
                Escrow Agent shall sell such Escrowed Shares on the open market
                and shall retain the proceeds of sale, less any expenses
                incurred in realizing such sale (the "Proceeds") as escrowed
                property for such Non-Affiliate. The Escrow Agent shall invest
                such Proceeds according to the written instructions of such
                Non-Affiliate for the duration of the escrow. The Escrow Agent
                shall keep complete records of any such sales of Escrowed
                Shares.

        3.3     At any time after receipt by the Escrow Agent of written notice
                by Phoenix of the release, in the format prescribed by the SEC,
                of at least 30 days of post-combination financial results of
                Phoenix and ANAWA Holding AG, and provided that the Escrowed
                Shares are not then subject to any restrictions on transfer
                imposed by any Regulatory Authority, an Affiliate may also
                instruct the Escrow Agent to sell all or part of their portion
                of the Escrowed Shares in the manner set forth in Section 3.2.
                In such event, the Escrow Agent shall proceed as set forth in
                Section 3.2.

        3.4     Whenever Phoenix has a Claim it shall promptly give a Notice of
                Claim in respect thereof to the Vendors and the Escrow Agent.
                Upon receipt of a Notice of Claim, the Escrow Agent shall
                immediately reserve for distribution in accordance with the
                provisions of Section 3.5 hereof (but shall not release from
                escrow except in accordance with the provisions hereof) that
                number of the Escrowed Shares which is equal in value to the
                amount provided for in the Notice of Claim, calculated on the
                basis of the Escrowed Share Price for such Claim.

        3.5     Within 15 days of receipt of a Notice of Claim, the Vendors (or
                any of them) shall give to Phoenix and the Escrow Agent a
                Response with respect to each Claim set forth therein. If:

                3.5.1   the Response indicates that the Vendors accept a Claim
                        set forth in the Notice of Claim, or if the Escrow Agent
                        does not receive a Response with respect to a Claim
                        within said 15 day period, the Vendors shall be deemed
                        to have irrevocably consented to each Claim so accepted
                        or in respect of which no Response is so received, as
                        made, and the Escrow Agent shall forthwith give written
                        notice thereof to Phoenix:

                3.5.1.1 setting forth the total amount of all Claims which have
                        been consented to and the number of shares from the
                        Escrowed Shares to be released from escrow for the
                        benefit of Phoenix (the "Released Shares"), being that
                        number of the Escrowed Shares which is equal in value to
                        the amount of the admitted Claims set forth in such
                        Notice of Claim, calculated on the basis of the Escrowed
                        Share Price for such Claim; and

                3.5.1.2 surrender for cancellation to Phoenix the share
                        certificate(s) in its possession representing the
                        Released Shares, duly endorsed for transfer, and the
                        Escrow Agent shall retain in its possession the other
                        share certificate(s) representing the balance of the
                        Escrowed Shares, if any, to be held by it in escrow and
                        dealt with in accordance with the terms hereof; or




                                      -6-


                3.5.2   the Response indicates that the Vendors (or any of them)
                        dispute a Claim set forth in the Notice of Claim
                        (whether or nor arbitration proceedings have been
                        instituted), the Escrow Agent shall retain in its
                        possession and continue to hold in escrow that number of
                        the Escrowed Shares which is equal in value to the
                        amount provided for in the disputed Claims, calculated
                        on the basis of the Escrowed Share Price for such Claim:

                        3.5.2.1 until the Escrow Agent receives a joint 
                                written notice from Phoenix and the Vendors 
                                directing the Escrow Agent as to the manner 
                                in which such Escrowed Shares and the share 
                                certificate(s) representing same are to be 
                                dealt with, in which case the Escrow Agent 
                                shall deal with same in accordance with such 
                                joint written instructions; or

                        3.5.2.2 in the absence of such a joint written notice 
                                within 10 business days of the Escrow Agent's 
                                receipt of the Response, the Escrow Agent 
                                shall deal with such Escrowed Shares and the 
                                share certificate(s) representing same in 
                                accordance with a final arbitration order in 
                                respect of such disputed Claim(s) pursuant to 
                                the arbitration contemplated by Section 12 
                                hereof. Any arbitration order shall be 
                                accompanied by a legal opinion by counsel for 
                                the presenting party satisfactory to the 
                                Escrow Agent to the effect that the said 
                                order is final and non-appealable.

        3.6     If, at the time of receipt by the Escrow Agent of any Notice of
                Claim as provided for in Section 3.4 hereof, the Escrowed Shares
                remaining in escrow for the account of any Vendor calculated on
                the basis of the Escrowed Share Price is insufficient to meet
                such Vendor's pro rata portion of the number of Released Shares
                to be remitted to Phoenix, the balance of such Vendor's pro rata
                portion of the admitted Claims shall be satisfied by payment in
                cash from the Proceeds of those Escrowed Shares sold by the
                Escrow Agent at the direction of such Vendor pursuant to Section
                3.2 or 3.3 hereof.

        3.7     On the earlier of (i) November 30, 1998, or (ii) the date at
                which the Escrow Agent receives a notice from Phoenix confirming
                that the audit of the combined financial statements of Phoenix
                and ANAWA Holding AG has been completed, the Escrow Agent will
                deliver the Escrowed Shares and all Distributions and Proceeds
                to the Vendors, pro rata to their respective interests in the
                Escrowed Shares, Distributions and Proceeds, if any, with the
                exception of such number of Escrowed Shares calculated on the
                basis of the Escrowed Share Price as may be necessary to satisfy
                any obligation to indemnify for a Specific Contingency which has
                not yet occurred. The notice from Phoenix referred to above
                shall indicate the maximum amount of Specific Contingencies
                which have not been prescribed or definitively settled and the
                number of Escrowed Shares, calculated on the basis of the
                Escrowed Share Price, which may not be released from the escrow
                for such Specific Contingencies. In calculating the maximum
                amount of Specific Contingencies which have not been prescribed
                or definitively settled and the number of Escrowed Shares which
                may be released, Phoenix and the Vendors acknowledge that the
                number of Escrowed Shares relating to the Specific Contingency
                referred to in Section 8.2 of the Purchase Agreement is
                calculated using the Escrowed Share Price provided in Section
                1.1.5 hereof and an amount of SFr220,000 as opposed to
                Sfr1,100,000. The number of Escrowed Shares relating to any
                other Specific Contingency is calculated using the amounts
                mentioned in 




                                      -7-


                Section 8 of the Purchase Agreement and the Escrowed Share Price
                provided in Section 1.1.5 hereof.

        3.8     Upon receipt by the Escrow Agent from Phoenix of a written
                notice instructing it to release, pro rata to the Vendors, such
                further number of Escrowed Shares as is no longer necessary to
                satisfy remaining indemnification obligations in respect of the
                maximum amount of remaining Specific Contingencies which have
                been prescribed or definitively settled, the Escrow Agent shall
                so release such number of Escrowed Shares to the Vendors, pro
                rata to their respective interests in the Escrowed Shares,
                Distributions and Proceeds, if any. It is agreed between Phoenix
                and the Vendors that the Specific Contingency referred to in
                Section 8.2 of the Purchase Agreement will be considered
                prescribed or definitively settled for the purposes hereof if on
                the third anniversary hereof no legal proceedings have been
                instituted against ANAWA Holding AG by Dr. Rondez AG. Phoenix
                hereby undertakes to notify the Escrow Agent promptly when a
                Specific Contingency becomes prescribed or definitively settled.

4.      VOTING RIGHTS

        4.1     The Escrow Agent shall provide to each of the Vendors a proxy
                entitling such Vendor to vote those of the Escrowed Shares which
                are owned by it, forthwith upon the Escrow Agent's receipt
                thereof in its capacity as registered shareholder of Phoenix, in
                order to allow each Vendor to vote its Escrowed Shares in the
                same manner as if it were the registered owner thereof.

5.      RIGHTS AND OBLIGATIONS OF THE ESCROW AGENT

        5.1     The Escrow Agent is not a party to, and is not bound by, any
                provisions which may be evidenced by, or arise out of, any
                agreement other than as therein set forth under the express
                provisions of this Agreement.

        5.2     The Escrow Agent acts hereunder as a depositary only and is not
                responsible or liable in any manner whatever for the
                sufficiency, correctness, genuineness or validity of any
                instrument deposited with it, or for the form of execution of
                such instrument or for the identity or authority or right of any
                person or party executing or depositing it.

        5.3     The Escrow Agent shall not be under any duty to give the
                Escrowed Shares, Distributions and Proceeds, if any, held by it
                hereunder any greater degree of care than it gives its own
                similar property and shall not be required to invest any funds
                held hereunder except as directed in this Agreement. Uninvested
                funds held hereunder shall not earn or accrue interest.

        5.4     The Escrow Agent shall not be liable, except for its own gross
                negligence or willful misconduct and, except with respect to
                claims based upon such gross negligence or willful misconduct
                that are successfully asserted against the Escrow Agent, the
                other parties hereto shall solidarily indemnify and hold
                harmless the Escrow Agent (and any successor Escrow Agent) from
                and against any and all losses, liabilities, claims, actions,
                damages and expenses, including reasonable attorney's fees and
                disbursements, arising out of and in connection with this
                Agreement. Without limiting the foregoing, the Escrow Agent
                shall in no event be liable in connection with its investment or
                reinvestment of any cash held by it hereunder in good faith, in
                accordance with the terms hereof.




                                      -8-


        5.5     The Escrow Agent shall be entitled to rely upon any order,
                judgment, certification, demand, notice, instrument or other
                writing delivered to it hereunder without being required to
                determine the authenticity or the correctness of any fact stated
                therein or the propriety or validity of the service thereof. The
                Escrow Agent may act in reliance upon any instrument or
                signature believed by it to be genuine and may assume that the
                person purporting to give receipt or advice or make any
                statement or execute any document in connection with the
                provisions hereof has been duly authorized to do so. The Escrow
                Agent may conclusively presume that the undersigned
                representative of any party hereto which is an entity other than
                a natural person has full power and authority to instruct the
                Escrow Agent on behalf of that party unless written notice to
                the contrary is delivered to the Escrow Agent.

        5.6     The Escrow Agent may act pursuant to the advice of counsel with
                respect to any matter relating to this Agreement and shall not
                be liable for any action taken or omitted by it in good faith in
                accordance with such advice.

        5.7     The Escrow Agent makes no representation as to the validity,
                value, genuineness or the collectability of any security or
                other document or instrument held by or delivered to it.

        5.8     The Escrow Agent shall not be called upon to advise any party as
                to the wisdom in selling or retaining or taking or refraining
                from any action with respect to any securities or other property
                deposited hereunder.

        5.9     The Escrow Agent (and any successor Escrow Agent) may at any
                time resign as such by delivering the Escrowed Shares,
                Distributions and Proceeds, if any, to any successor Escrow
                Agent jointly designated by the other parties hereto in writing,
                or to any court of competent jurisdiction, whereupon Escrow
                Agent shall be discharged of and from any and all further
                obligations arising in connection with this Agreement. The
                resignation of Escrow Agent will take effect on the earlier of
                (a) the appointment of a successor (including a court of
                competent jurisdiction) or (b) the day which is 30 days after
                the date of delivery of its written notice of resignation to the
                other parties hereto. If at that time Escrow Agent has not
                received a designation of a successor Escrow Agent, Escrow
                Agent's sole responsibility after that time shall be to retain
                and safeguard the Escrowed Shares and Proceeds, if any, until
                receipt of a designation of successor Escrow Agent or a joint
                written disposition instruction by the other parties hereto or a
                final non-appealable order of a court of competent jurisdiction.

        5.10    Phoenix and the Vendors shall pay Escrow Agent compensation (as
                payment in full) for the services to be rendered by Escrow Agent
                hereunder in the amount of $1,500 at the time of execution of
                this Agreement and agree to reimburse Escrow Agent for all
                reasonable expenses, disbursements and advances incurred or made
                by Escrow Agent in performance of its duties hereunder
                (including reasonable fees, expenses and disbursements of its
                counsel).




                                      -9-


6.      LIMITED RESPONSIBILITY

        This Agreement expressly sets forth all the duties of Escrow Agent with
        respect to any and all matters pertinent hereto. No implied duties or
        obligations shall be read into this Agreement against the Escrow Agent.
        The Escrow Agent shall not be bound by the provisions of any agreement
        among the other parties hereto except this Agreement. No trust is
        created by this Agreement and the Escrow Agent does not act in any
        capacity as a trustee. In the event of any disagreement between any of
        the parties to this Agreement, or between them or either of them and any
        other person, resulting in demands or adverse claims being made in
        connection with or for any asset involved herein or affected hereby, the
        Escrow Agent shall be entitled, at its discretion, to refuse to comply
        with any demands or claims on it, as long as such disagreement shall
        continue, and in so refusing the Escrow Agent may make no delivery or
        other disposition of any asset involved herein or affected hereby, and
        in so doing the Escrow Agent shall not be or become liable in any way or
        to any person or party for its failure or refusal to comply with such
        conflicting demands or adverse claims, and it shall be entitled to
        continue so to refrain from acting and so to refuse to act until the
        right of person or party shall have been finally settled as provided in
        Section 12 hereof, or all differences shall have been adjusted by
        agreement and the Escrow Agent shall have been notified thereof in
        writing signed by all persons and parties interested.

        (a) no claim or right arising out of this Agreement or the documents

        giving such notice or demand to take further action without notice or
        demand as provided in this Agreement or the documents referred to in
        this Agreement.
