In return for such surrender and cancellation, Chalone will issue to DBR a total of 1,769,143 shares of Chalone's no par value common stock ("Common Stock"). (ii) Third-Party Debentures. Chalone shall, no later than May 15, 1995, have extended an offer to each of the other four holders of its 5% Convertible Subordinated Debentures Due 1999, in aggregate face amount of $8,500,000, also to surrender their debentures to Chalone at the Closing, for conversion and cancellation, in exchange for Chalone's issuance of shares of Common Stock at the rate of one share for each $7.00 principal amount of debentures. (The DBR debentures discussed in subparagraph 1(a)(i) and the Third-Party Debentures discussed in this subparagraph 1(a)(ii) shall collectively herein be referred to as the "Debentures.") The acceptance or non-acceptance of this offer, by any one or more of the aforesaid Third-Party Debenture-holders, shall not in any way affect DBR's agreement to convert, as set forth in subparagraph 1(a)(i), immediately above, nor in any way affect any other provision of this Agreement. (iii) Interest. Interest on all of the aforesaid Debentures will continue to accrue and be payable, in cash, according to the terms of the Debentures, until conversion. Accrued interest to the date of the Closing will, for such Debentures as are surrendered for conversion hereunder, be paid at the Closing. The foregoing notwithstanding, DBR may at its election, upon giving five business days' prior notice to Chalone, elect to set off against the amount that it is required to pay at the Closing under subparagraph 1(b) hereof the amount that Chalone will be required to pay to DBR at the Closing, as accrued interest, pursuant to this subparagraph 1(a)(iii). b. Sale and Purchase of Stock and Warrants. At the Closing, and subject to the terms and conditions of this Agreement, Chalone shall sell and issue to each of DBR and Summus, and each of DBR and Summus agrees, severally and not jointly, to purchase a total of 416,667 Units of Chalone's securities, each Unit consisting of one share of Chalone's Common Stock and one Warrant (as identified below) for the purchase of one share of Common Stock at an exercise price of $8.00, for a per-Unit purchase price of $6.00 and an aggregate purchase price of $2,500,002, each. At the Closing, Chalone shall deliver to each of DBR and Summus a stock certificate registered in that party's name or the name of that party's nominee (as the party shall so direct) representing the said 416,667 shares of Common Stock and a Warrant, dated as of the Closing and substantially in the form attached hereto as Exhibit "A" ("Warrant"). Each of DBR and Summus shall either deliver to Chalone a certified or cashier's check payable to Chalone's order or a wire transfer of immediately available funds to Chalone's designated bank account, each in the sum of $2,500,002. c. Right to Purchase Additional Shares. (i) In the event Chalone shall, subsequent to the Closing, sell any of its Common Stock, or securities convertible into Common Stock, or grant options for the purchase of Common Stock (collectively, "Securities") (except for sales, grants or issuances pursuant to any of the Plans or other reservations described in subparagraph 7(b), hereafter, and except for Common Stock issued in exercise of previously-issued Warrants or issued to the holders of third-party Debentures converted subsequent to the Closing), each of DBR and Summus shall EXHIBIT 2 have the right to purchase that amount of the particular Securities then being issued, on the same terms and conditions as the remainder of the issuance, as will cause DBR's or Summus's (as applicable) voting power in Chalone immediately upon the completion of such issuance to be not less than such voting power immediately prior to the issuance. (ii) If an offering subject to this subsection is not to be registered under the U.S. Securities Act of 1933, Chalone shall notify DBR and Summus of the general terms and conditions of the offering, and each of DBR and Summus, each acting for itself, shall have 30 days thereafter in which to notify Chalone as to whether it desires to purchase all or part of the Securities that it has the right to purchase pursuant to this subsection. (iii) If an offering subject to this subsection is to be registered under the Securities Act of 1933, Chalone shall advise DBR and Summus that such offering is being contemplated at least 30 days before the initial filing of a registration statement, to obtain an initial expression of interest. Chalone shall further notify DBR and Summus not less than five days prior to the effective date of such registration statement of the anticipated terms and initial price range of the offering. Each of DBR and Summus, each acting for itself, shall have three days after such five-day notice within which to notify Chalone as to whether it will purchase the Securities to which it is entitled hereunder assuming they are sold at not more than the maximum price specified in the anticipated price range. If either DBR or Summus has so agreed to the purchase, prior to the effective date of such registration statement, but it is subsequently determined that the Securities can reasonably be expected to be sold at a price above the previously specified maximum price, Chalone shall notify such party (DBR and/or Summus, as applicable), at least three business days prior to any sale at such higher price, of the then anticipated maximum offering price; DBR and/or Summus, as applicable, shall have one business day after such notice within which to notify Chalone as to whether it will purchase the Securities to which it is entitled hereunder assuming they are sold at not more than the maximum of the new anticipated price range. 2.

The foregoing notwithstanding, DBR covenants and agrees that it will not, directly or indirectly, increase its total holding of Chalone Common Stock, including securities exercisable for or convertible into Common Stock, to more than 49.9%, on a fully diluted basis, through December 31, 1999; provided, however, that this limitation shall not be considered violated if DBR's percentage ownership is increased to more than 49.9% by reason of Chalone's repurchase or other acquisition of shares of its outstanding Common Stock, unaccompanied by any contemporaneous (or subsequent) purchase or other acquisition by DBR. Options to purchase shares of Common Stock, obtained and held by designees of DBR as members of Chalone's Board of Directors pursuant to Chalone's Non-Discretionary Stock Option Plan, and shares of Common Stock issued on exercise of such options, although in other respects the property of the individual holder, shall be counted for computational purposes of this paragraph 5 as a part of the holding of DBR. 6.

Chalone shall provide DBR and Summus with copies 3 of any shareholder communication prepared in connection with this paragraph 6 or otherwise prepared in connection with such meeting, reasonably in advance of the mailing date of such communication.

Compliance With Laws. Chalone and its business and operations, as currently conducted, have been and are being conducted in accordance with all applicable federal, state and local laws, rules and regulations, and with all necessary licenses, permits or other governmental authorizations, except where any failure so to comply would not have a material adverse effect on said business and operations taken as a whole. g.

SEC Documents. Chalone has furnished to DBR and Summus a true and complete copy of any statement, report, registration statement or definitive proxy statement filed by Chalone with the SEC since December 31, 1994 (the "Chalone SEC Documents").

No Actions Pending. No action, suit, arbitration or other proceeding or investigation has been filed or commenced (other than actions that may have been filed but without Chalone having been served or otherwise made aware of the filing or other commencement) against Chalone or involving any of its properties or interests or, to the best knowledge of Chalone, threatened (in writing to an officer of Chalone or orally communicated to its President or Chief Financial Officer) against Chalone or in respect of any of its properties or interests, at law or in equity, before any court, governmental department, commission, board or other federal, state, or other instrumentality, agency or authority, foreign or domestic, an adverse decision in which could reasonably be expected to affect adversely the power of Chalone to execute and deliver, or the ability of Chalone to perform its obligations under, this Agreement, or result in any material adverse change in Chalone's business, properties, assets, or condition (financial or otherwise), taken as a whole, or which questions the validity of this Agreement or the sale and issuance of the Securities. m.

Material Contracts. All contracts material to the business or financial condition of Chalone, taken as a whole, have been filed as exhibits to Chalone's Annual Reports on Form 10-K or incorporated therein by reference, and all of Chalone's material contracts currently in effect are listed as exhibits to Chalone's Annual Report on Form 10-K for 1994. A copy of the Exhibit Index from the 1994 Form 10-K is attached hereto as Schedule B. o. Absence of Undisclosed Liabilities. Except as set forth in its SEC-filed financial statements, Chalone does not have any obligations or liabilities that are material to Chalone, taken as a whole (whether accrued, absolute, contingent, unliquidated or otherwise, whether due or to become due and regardless of when asserted), other than liabilities and obligations that have arisen after March 31, 1995, in the ordinary course of business. 8.

Restricted Securities.

Each Purchasing Party also acknowledges that it understands that any sale of the Securities which might be made by it in reliance upon Rule 144 may be made only in limited amounts in accordance with the terms and conditions of that Rule. e.

Without in any way limiting the representations set forth above, each Purchasing Party agrees not to make any disposition of all or any portion of the Securities unless and until: (i) there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or (ii) such Purchasing Party shall have notified Chalone of the proposed disposition, shall have furnished Chalone with such information concerning the proposed disposition as Chalone may reasonably request, and either shall have furnished Chalone with an opinion of counsel, reasonably satisfactory in substance to Chalone, that such disposition will not require registration of the Securities under the Securities Act, or Chalone has reasonably determined that such disposition is in compliance with Rule 144. i.

Share Transfers. Chalone shall not be required to transfer on its books any Securities which shall have been sold or transferred in violation of any of the provisions in this Agreement or to treat as owner of such Securities or to accord the right to vote as such owner or to pay dividends to any transferee to whom such Securities shall have been so transferred. l.
