                                   ARTICLE IV
                            RESTRICTIONS ON TRANSFER

     4.1 GENERAL. Voting Stock may not be transferred by Purchaser or any
subsequent transferee, except to a transferee who agrees to comply with all
restrictions on transfer of Voting Stock provided for in this Agreement and the
certificates for Voting Stock and all other restrictions of this Agreement
applicable by their terms to transferees. Any purported transfer in violation of
the preceding sentence shall be void.

     4.2 SECURITIES LAW COMPLIANCE. The holder of Voting Stock shall not offer,
sell, transfer, pledge, or otherwise dispose of Voting Stock in violation of any
applicable securities or other laws of a governmental authority having
jurisdiction over such disposition.

     4.3 VOLUNTARY TRANSFERS. If Purchaser wishes to transfer any Voting Stock,
Purchaser must first offer to transfer the Voting Stock to Vinifera. The offer
shall be made by giving Vinifera written notice of the proposed transfer (the
"Proposed Transfer Notice"). The Proposed Transfer Notice must state (i) that
Purchaser intends to transfer the Voting Stock; (ii) the number of shares of
Voting Stock involved in the proposed transfer; (iii) the terms of the proposed
transfer, including the name and address of the proposed transferee; and (iv)
the price per share and the terms of payment. The Proposed Transfer Notice shall
constitute an offer to transfer the Voting Stock to Vinifera at the price and on
the terms of the proposed transfer.

     4.4 INVOLUNTARY TRANSFERS.

        (a) DEATH. If Purchaser is an individual, upon Purchaser's death,
     Purchaser (or Purchaser's personal representative, whether or not
     properly qualified) shall be deemed to have made an offer to sell to
     Vinifera all of Purchaser's Voting Stock for its fair market value as
     determined by Vinifera's board of directors; provided, however, that
     no such offer shall be deemed made if Purchaser's Voting Stock will be
     transferred solely to Purchaser's spouse or children as a result of
     Purchaser's death and such persons make the agreement required of
     transferees under Section 4.1.

        (b) INVOLUNTARY LIFETIME TRANSFER. If Purchaser (a) becomes a
     debtor under the United States Bankruptcy Code (voluntarily or
     involuntarily) or any similar foreign law; or (b) makes a general
     assignment for the benefit of creditors or permits any of Purchaser's
     Voting Stock to be attached or levied upon or to become subject to
     judicial sale or execution of judgment; or (c) would, but for this
     Agreement, be required to involuntarily transfer Voting Stock as a
     result of any other event; Purchaser shall be deemed, immediately
     before such event occurs, to have made an offer to sell to Vinifera
     all of the Voting Stock then owned by Purchaser for its fair market
     value as determined by Vinifera's board of directors.

<PAGE>

     4.5 ACCEPTANCE OF OPTION TO PURCHASE.

        (a) OPTION PERIOD. For 30 days after Vinifera receives a Proposed
     Transfer Notice or learns of an event giving rise to an option to
     purchase Voting Stock under Section 4.4 (the "Option Period"),
     Vinifera shall have the option to purchase some or all of the offered
     Voting Stock. The decision whether to exercise the option shall be
     made by Vinifera's board of directors or, if a disinterested quorum of
     the board of directors cannot be convened, at a special shareholders'
     meeting. If the decision is made at a special shareholders' meeting,
     Purchaser hereby grants an irrevocable proxy to the remaining
     shareholders to vote Purchaser's Voting Stock in accordance with the
     majority of the other votes cast, excluding Purchaser's Voting Stock.

        (b) ELECTION. Vinifera may elect to purchase any of the offered
     Voting Stock by giving written notice to Purchaser within the Option
     Period specifying the number of shares of Voting Stock that Vinifera
     is electing to purchase and the total purchase price of the shares.

     4.6 PAYMENT AND TRANSFER OF SHARES. Vinifera shall designate a transfer
date, which shall be within 30 days after the Option Period (the "Transfer
Date"). On the Transfer Date, the Purchaser or Purchaser's legal representative
must transfer and deliver the certificates for the Voting Stock, duly endorsed
for transfer, to Vinifera. On the Transfer Date, Vinifera must pay the purchase
price for the Voting Stock to Purchaser.

     4.7 POWER OF ATTORNEY. Purchaser irrevocably appoints each vice-president
of Vinifera as Purchaser's agent and attorney-in-fact, with full power of
substitution, for the limited purpose of effecting the transfer of Voting Stock
purchased by Vinifera under this Agreement. If, after tender to Purchaser on or
before the Transfer Date of the purchase price for the Voting Stock, Purchaser
does not deliver to Vinifera the Voting Stock to be transferred, any
vice-president, as Purchaser's agent and attorney-in-fact, may take all actions
and may execute all documents necessary to effect the transfer of the Voting
Stock to Vinifera. Upon the taking of such action and execution of such
documents, Purchaser shall have no further interest in the Voting Stock
transferred. Purchaser acknowledges and agrees that the granting of this power
of attorney is coupled with an interest and shall survive Purchaser's death or
disability, if Purchaser is an individual, and Purchaser's assignment of any
interest in the Voting Stock.

     4.8 REJECTION OF OFFER BY COMPANY. If Vinifera does not purchase Voting
Stock offered in a Proposed Transfer Notice, the Voting Stock may be transferred
to the proposed transferee within three months after the Option Period subject
to the following conditions: (i) the transferee must become a party to this
Agreement; (ii) the transferee and the transferor must certify to Vinifera the
terms of the transfer; and (iii) the transfer must be made at a price and on
terms and conditions no more favorable to Purchaser than those specified in the
Proposed Transfer Notice. If Vinifera does not purchase Voting Stock offered
pursuant to Section 4.4, the Voting Stock may be transferred within six months
after the Option Period in connection with the event giving rise to Vinifera's
purchase option, subject to the condition that the transferee must become a
party to this Agreement. If a transfer is not made within the applicable
three-

<PAGE>
month or six-month period, no transfer shall be made without again offering the
Voting Stock as provided above.

     4.9 LOCK-UP AGREEMENT. In the event of an underwritten public offering of
the capital stock of Vinifera, Purchaser shall not transfer any Shares except
pursuant to the registration statement filed with the Securities and Exchange
Commission for the offering for a period of 15 days prior to and 180 days after
the effective date of such registration statement without the underwriters'
consent, provided that Agritope and any Vinifera directors and executive
officers holding Voting Stock agree to similar transfer restrictions in
connection with the offering.

     4.10 CERTIFICATE LEGEND. Certificates for Purchaser's Voting Stock shall
bear substantially the following legend:

        THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO TRANSFER
        RESTRICTIONS SET FORTH IN A STOCK PURCHASE AGREEMENT AMONG AGRITOPE,
        INC., VINIFERA, INC., AND PURCHASER, DATED JUNE 1, 1999.


     4.11 PURCHASER'S RIGHT OF FIRST REFUSAL.

        (a) DURATION OF RIGHT. Agritope shall provide Purchaser with the
     rights set forth in this Section 4.11 for the period beginning on the
     day after the Initial Closing Date and ending on the earliest to occur
     of (i) the Third Anniversary Closing Date, (ii) the date on which
     shares of capital stock of Vinifera are publicly traded, and (iii) the
     date on which Agritope owns less than a majority of the Voting Stock
     of Vinifera.

        (b) RESTRICTION ON SALE OF SHARES. During the period described in
     Section 4.11(a), Agritope shall not sell any shares of Voting Stock
     for less than $2.50 per share to any party other than a current holder
     of Voting Stock, if as a result of such sale Agritope would own less
     than a majority of the Voting Stock, unless Agriope shall have first
     communicated to Purchaser, by written notice, a written offer
     ("Agritope's Offer") to sell an amount of such shares to Purchaser in
     proportion to the percentage of votes Purchaser is entitled to cast.
     The notice shall specify the consideration and general terms and
     conditions upon which Agritope is willing to sell such shares.

        (c) ACCEPTANCE OF OFFER. Purchaser shall have a period (the
     "Acceptance Period") of 30 days from the effective date of the notice
     of Agritope's Offer to give Agritope written notice of acceptance. If
     Agritope's Offer is accepted, the parties shall use their best efforts
     in good faith to negotiate and execute definitive agreements in
     accordance with the terms of Agritope's Offer by the date occurring 30
     days following acceptance or by such later date as may be specified in
     Agritope's Offer (the "Expiration Date").

<PAGE>


        (d) SALE TO THIRD PARTY. If Purchaser does not accept Agritope's
     Offer within the Acceptance Period, or if mutually acceptable
     definitive agreements have not been negotiated and executed by
     Purchaser by the Expiration Date, Agritope may sell the shares offered
     to Purchaser to any other party pursuant to an agreement executed
     within 180 days following the earlier of the expiration of the
     Acceptance Period or the effective date of any written notice of
     rejection of Agritope's Offer by Purchaser. The agreement shall
     contain the same price, terms, and conditions as those specified in
     Agritope's Offer (or terms and conditions more favorable to Agritope).
     Nothing in this Section 4.11 shall restrict the issuance and sale to a
     third party of shares not required to be offered to Purchaser pursuant
     to Section 4.11(b).

                                   ARTICLE V
