Other Events. On March 29, 1995, Circa Pharmaceuticals, Inc. (the "Registrant") entered into a definitive Agreement and Plan of Merger, dated as of March 29, 1995, by and among Watson Pharmaceuticals, Inc. ("Watson"), Gum Acquisition Corp., a wholly-owned subsidiary of Watson ("Watson Sub") and the Registrant (the "Merger Agreement"), pursuant to which Watson Sub will merge (the "Merger") with and into the Registrant, with the Registrant being the surviving corporation in the Merger. As a result of the Merger, Circa will become a wholly-owned subsidiary of Watson. It is intended that the Merger will qualify as a "pooling of interests" for accounting purposes and that the Merger will constitute a tax free reorganization for federal income tax purposes. Pursuant to the terms and conditions of the Merger Agreement, at the effective time of the Merger, each share of common stock, par value $.01 per share, of the Registrant (the "Registrant Common Stock") will be converted into the right to receive .86 of a share (the "Exchange Ratio") of the common stock, par value $.0033 per share, of Watson (the "Watson Common Stock"). If, during a measurement period prior to the date scheduled for the Registrant's stockholders' vote on the Merger, the average price of Watson Common Stock is less than $25.00, the Registrant may terminate the Merger Agreement unless Watson agrees to a specified upward adjustment in the Exchange Ratio. Consummation of the Merger is subject to the satisfaction of certain conditions, including approval by the Registrant's stockholders of the Merger Agreement, receipt of regulatory approvals and treatment of the Merger as a "pooling of interests" for accounting purposes. In the event of termination under specified conditions, one party to the Merger Agreement may be entitled to receive a fee of up to $15 million from the other and payment of its expenses. A copy of the Merger Agreement is attached as Exhibit 10.1 and is hereby incorporated by reference.

WHEREAS, the Board of Directors of each of Watson and CIRCA have determined that a business combination between Watson and CIRCA is in the best interests of their respective companies and stockholders and presents an opportunity for their respective companies to achieve long-term strategic and financial benefits, and, accordingly, have approved and adopted this Agreement and the transactions contemplated hereby and recommend approval thereof by their respective stockholders; and WHEREAS, the respective Boards of Directors of Watson and CIRCA have determined that the merger provided for herein is fair to their respective stockholders; and WHEREAS, it is the intention of the parties to this Agreement that for federal income tax purposes, the merger provided for herein shall qualify as a "reorganization" within the meaning of Section 368 of the Internal Revenue Code of 1986, as amended (the "Code"); and WHEREAS, for accounting purposes, it is intended that the Merger shall be accounted for as a "pooling of interests;" and WHEREAS, Watson has delivered to CIRCA voting agreements executed by the holders of more than 17% of Watson's outstanding voting stock; NOW, THEREFORE, in consideration of the premises and of the representations, warranties, covenants and agreements set forth herein, the parties hereto hereby agree as follows: ARTICLE I THE MERGER Section 1.1 The Merger. Upon the terms and subject to the conditions of this Agreement, at the Effective Time (as defined in Section 1.3 of this Agreement), Merger Sub shall be merged with and into CIRCA in accordance with the laws of the States of Nevada and New York and the terms of this Agreement (the "Merger"), whereupon the separate corporate existence of Merger Sub shall cease, and CIRCA shall be the surviving corporation of the Merger (sometimes referred to herein as the "Surviving Corporation"). Section 1.2 Closing. Subject to the terms and conditions of this Agreement, the closing of the Merger (the "Closing") shall take place (a) at the offices of D'Ancona & Pflaum, 30 North LaSalle Street, Suite 2900, Chicago, Illinois 60602 at 10:00 a.m. on the second business day after all the conditions set forth in Article VI of this Agreement (other than those that are waived by the party or parties for whose benefit such conditions exist) are satisfied; or (b) at such other place, time, and/or date as the parties hereto may otherwise agree. The date upon which the Closing shall occur is referred to herein as the "Closing Date." Section 1.3 Effective Time. As soon as practical after all the conditions to the Merger set forth in Article VI of this Agreement have been fulfilled or waived and this Agreement shall not have been terminated as provided in Article VII hereof, the parties hereto shall cause certificates of merger to be properly executed and filed in accordance with the laws of the States of Nevada and New York and the terms of this Agreement. The parties hereto shall also take such further actions as may be required under the laws of the States of Nevada and New York in connection with the consummation of the Merger. The Merger shall become effective at such time as the certificates of merger are duly filed with the Secretary of State of the States of Nevada and New York or at such later time as is specified in the certificates of merger (the "Effective Time"). From and after the Effective Time, the Surviving Corporation shall possess all the rights, privileges, powers and franchises and be subject to all of the restrictions, disabilities, liabilities and duties of CIRCA and Merger Sub, all as provided under applicable law. Section 1.4 Conversion of Shares. (a) At the Effective Time: (i) each share of Common Stock, par value $.01 per share, of Merger Sub outstanding immediately prior to the Effective Time shall be converted into and exchanged for one share of Common Stock, par value $.01 per share, of the Surviving Corporation; and (ii) each share of Common Stock, par value $0.01 per share (the "CIRCA Common Stock"), of CIRCA outstanding immediately prior to the Effective Time plus the associated rights described in Section 5.13 hereof (the "CIRCA Rights"), by virtue of the Merger and without any action on the part of the holder thereof, except as otherwise provided in Sections 1.4(c) or 1.8 hereof, shall be converted into the right to receive 0.86 of a share of Common Stock, par value $0.0033 per share (the "Watson Common Stock"), of Watson (such ratio, as adjusted as contemplated pursuant to Section 1.7 and 7.3(g), being referred to herein as the "Exchange Ratio"). The Exchange Ratio shall be rounded to the nearest ten-thousandth of a share. To the extent such plan is adopted on or prior to the Effective Time, each 2 share of Watson Common Stock issued to holders of CIRCA Common Stock in the Merger shall be issued together with one associated stock purchase right (a "Right") in accordance with a Rights Agreement to be entered into by Watson. References herein to the shares of Watson Common Stock issuable in the Merger shall be deemed to include the associated Rights, if so issued; and references herein to shares of CIRCA Common Stock to be cancelled pursuant to the Merger shall be deemed to include the associated CIRCA Rights. (b) As a result of the Merger and without any action on the part of the holder thereof, at the Effective Time, all shares of CIRCA Common Stock shall cease to be outstanding and shall be cancelled and retired and shall cease to exist, and each holder of shares of CIRCA Common Stock shall thereafter cease to have any rights with respect to such shares of CIRCA Common Stock, except for the right to receive (except as otherwise provided in Section 1.8 hereof), without interest, the Watson Common Stock and cash for fractional shares of Watson Common Stock in accordance with Section 1.6 of this Agreement upon the surrender of a certificate (each, a "Certificate") representing such shares of CIRCA Common Stock in accordance with the provisions of this Article I. (c) Each share of CIRCA Common Stock held by CIRCA as treasury stock or owned by Watson or any Subsidiary (as defined in Section 1.4(d) of this Agreement) of Watson immediately prior to the Effective Time shall be canceled, and no payment shall be made with respect thereto. (d) For purposes of this Agreement, (i) the term "Average Closing Price" shall mean the average of the per share daily closing price of Watson Common Stock as quoted on the NASDAQ National Market System ("NASDAQ") (and as reported by The Wall Street Journal or, if not reported thereby, by another authoritative source) during the twenty (20) consecutive trading days ending on the Determination Date (as defined in Section 7.3); (ii) the word "Subsidiary" when used with respect to any Person means any corporation or other organization, whether incorporated or unincorporated, of which (A) at least 15% of the securities or other interests having by their terms ordinary voting power to elect a majority of the board of directors or others performing similar functions with respect to such corporation or other organization is directly or indirectly owned or controlled by such Person or by any one or more of its Subsidiaries or (B) such Person or any other Subsidiary of such Person is a general partner, it being understood that representations and warranties of a Person concerning any former Subsidiary of such Person shall be deemed to relate only to the periods during which such former Subsidiary was a Subsidiary of such Person, provided, however, that "Subsidiary" shall not include any non-wholly owned entity of such Person if (a) such Person has, in the aggregate, invested or committed to invest less than $1,000,000 and (b) such entity generated less than 3 $10,000,000 of net revenues in such entity's last fiscal year; (iii) the word "Person" means an individual, a corporation, a partnership, an association, a trust or any other entity or organization, including a government or political subdivision or any agency or instrumentality thereof, or any affiliate (as that term is defined in the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (the "Exchange Act")) of any of the foregoing; (iv) the term "executive officers of Watson" (and similar formulations) shall mean those persons identified as such in the Watson Disclosure Letter (as hereinafter defined); and (v) the term "executive officers of CIRCA" (and similar formulations) shall mean those persons identified as such in the CIRCA Disclosure Letter (as hereinafter defined). Section 1.5 Stock Options; Restricted Stock. (a) All options (individually, a "CIRCA Option" and collectively, the "CIRCA Options") outstanding at the Effective Time under any CIRCA Stock Option Plan or Purchase Plan (the "CIRCA Stock Option Plans") shall remain outstanding following the Effective Time. At the Effective Time, such CIRCA Options shall, by virtue of the Merger and without any further action on the part of CIRCA or the holder of such CIRCA Options, be assumed by Watson in such manner that Watson (a) is a corporation (or a parent or a subsidiary corporation of such corporation) "assuming a stock option in a transaction to which Section 424(a) applied" within the meaning of Section 424 of the Code; or (b) to the extent that Section 424 of the Code does not apply to any such CIRCA Options, would be such a corporation (or a parent or a subsidiary corporation of such corporation) were Section 424 applicable to such option. At the Effective Time, (i) all references in the CIRCA Stock Option Plans to CIRCA shall be deemed to refer to Watson and (ii) Watson shall issue to each holder of a CIRCA Option a document evidencing the assumption of such option by Watson in accordance herewith. Each CIRCA Option assumed by Watson (as assumed, the "Watson Options") shall be exercisable upon the same terms and conditions including, without limitation, vesting (other than those options the vesting of which is accelerated by virtue of the Merger, as described in the CIRCA Disclosure Letter), as under the applicable CIRCA Stock Option Plan and the applicable option agreement issued thereunder, except that (x) each such CIRCA Option shall be exercisable for that whole number of shares of Watson Common Stock (to the nearest whole share) into which the number of shares of CIRCA Common Stock subject to such CIRCA Option immediately prior to the Effective Time would be converted under Section 1.4 of this Agreement; and (y) the option price per share of Watson Common Stock shall be an amount equal to the option price per share of CIRCA Common Stock subject to such CIRCA Option in effect immediately prior to the Effective Time divided by the Exchange Ratio (the option price per share, as so determined, being rounded upward to the nearest full cent). The date of grant of each Watson Option shall be the date on which the corresponding 4 CIRCA Option was granted. No payment shall be made for fractional interests. From and after the date of this Agreement, except as provided in Section 5.2(vi) of this Agreement, no additional options shall be granted by CIRCA or its Subsidiaries under the CIRCA Stock Option Plans or otherwise. Watson shall take all corporate actions necessary to reserve for issuance such number of shares of Watson Common Stock as will be necessary to satisfy exercises in full of all CIRCA Options after the Effective Time. (b) All shares of restricted CIRCA Common Stock issued as described in a schedule to the CIRCA Disclosure Letter shall, upon their conversion to Watson Common Stock pursuant to Section 1.4(a), be subject to the same terms and conditions (including, without limitation, vesting) to which such shares are currently subject, provided that all references to CIRCA in any agreement relating to such stock shall be deemed references to Watson. Section 1.6 Exchange of Certificates Representing CIRCA Common Stock. (a) As of the Effective Time, Watson shall deposit, or shall cause to be deposited, with an exchange agent selected by Watson, which shall be Watson's Transfer Agent or such other party reasonably satisfactory to CIRCA (the "Exchange Agent"), for the benefit of the holders of shares of CIRCA Common Stock, for exchange in accordance with this Section 1.6, certificates representing the shares of Watson Common Stock (such certificates for shares of Watson Common Stock, together with any dividends or distributions with respect thereto (relating to record dates for such dividends or distributions after the Effective Time), being hereinafter referred to as the "Exchange Fund") to be issued pursuant to Section 1.4 and paid pursuant to this Section 1.6 in exchange for outstanding shares of CIRCA Common Stock. The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Watson Common Stock contemplated to be issued pursuant hereto out of the Exchange Fund. Except as contemplated by Section 1.6(e) hereof, the Exchange Fund shall not be used for any other purpose. (b) Promptly after the Effective Time, Watson shall cause the Exchange Agent to mail to each holder of record of shares of CIRCA Common Stock immediately prior to the Effective Time (i) a letter of transmittal which shall specify that delivery shall be effected, and risk of loss and title to such shares of CIRCA Common Stock shall pass, only upon delivery of the Certificates representing such shares to the Exchange Agent and which shall be in customary form, and (ii) instructions for use in effecting the surrender of such Certificates in exchange for certificates representing shares of Watson Common Stock and cash in lieu of fractional shares. Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed and completed in accordance with the instructions thereto, the holder of the Certificate shall be entitled to receive in exchange 5 therefor (i) a certificate representing that number of whole shares of Watson Common Stock which such holder has the right to receive in respect of the shares of CIRCA Common Stock formerly represented by such Certificate (after taking into account all shares of CIRCA Common Stock then held by such holder); and (ii) a check representing the amount of cash in lieu of fractional shares, if any, and unpaid dividends and distributions after giving effect to any required withholding tax, if any, which such holder has the right to receive in respect of the Certificate surrendered pursuant to the provisions of this Section 1.6, and the shares represented by the Certificate so surrendered shall forthwith be cancelled. No interest will be paid or accrued on the cash in lieu of fractional shares and unpaid dividends and distributions, if any, payable to holders of shares of CIRCA Common Stock. In the event of a transfer of ownership of CIRCA Common Stock which is not registered in the transfer records of CIRCA, a certificate representing the proper number of shares of Watson Common Stock, together with a check for the cash to be paid in lieu of fractional shares, if any, and unpaid dividends and distributions, if any, may be issued to such a transferee if the Certificate representing such CIRCA Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid. (c) Notwithstanding anything to the contrary contained herein, no dividends or other distributions declared after the Effective Time on Watson Common Stock shall be paid with respect to any shares of CIRCA Common Stock represented by a Certificate until such Certificate is surrendered for exchange as provided herein. Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be paid to the holder of the certificates representing whole shares of Watson Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to such whole shares of Watson Common Stock and not paid, less the amount of any withholding taxes which may be required thereon; and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of Watson Common Stock, less the amount of any withholding taxes which may be required thereon. (d) At or after the Effective Time, there shall be no transfers on the stock transfer books of CIRCA of the shares of CIRCA Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation, they shall be cancelled and exchanged for certificates for shares of Watson Common Stock and cash in lieu of fractional shares, if any, deliverable in respect thereof pursuant to this Agreement in accordance with the 6 procedures set forth in this Section 1.6. Certificates surrendered for exchange by any person constituting an "affiliate" of CIRCA for purposes of Rule 145(c) under the Securities Act of 1933, as amended (the "Securities Act"), shall not be exchanged until Watson has received a written agreement from such person as provided in Section 5.9. (e) (i) No fractional shares of Watson Common Stock shall be issued pursuant hereto. In lieu of the issuance of any fractional share of Watson Common Stock pursuant to Section 1.4(b), cash adjustments will be paid as set forth herein. (ii) As promptly as practicable following the Effective Time, the Exchange Agent shall determine the excess of (x) the number of full shares of Watson Common Stock delivered to the Exchange Agent by Watson pursuant to Section 1.6(a) over (y) the aggregate number of full shares of Watson Common Stock to be distributed to holders of CIRCA Common Stock pursuant to Section 1.6(b) (such excess being herein called the "Excess Shares"). As soon after the Effective Time as practicable, the Exchange Agent, as agent for such holders of CIRCA Common Stock, shall sell the Excess Shares at then prevailing prices on the NASDAQ, all in the manner provided in paragraph (iii) of this Section. (iii) The sale of the Excess Shares by the Exchange Agent shall be executed on the NASDAQ through one or more member firms of the National Association of Securities Dealers, Inc. (the "NASD") and shall be executed in round lots to the extent practicable. Until the net proceeds of such sale or sales have been distributed to such holders of CIRCA Common Stock, the Exchange Agent will hold such proceeds in trust for such holders of CIRCA Common Stock (the "Trust"). Watson shall pay all commissions, transfer taxes and other out-of-pocket transaction costs of the Exchange Agent incurred in connection with such sale of Excess Shares.

To the knowledge of the executive officers of Watson, there are no pending or anticipated material claims against or otherwise involving any of the Watson Benefit Plans and no suit, action or other litigation (excluding claims for benefits incurred in the ordinary course of Watson Benefit Plan activities) has been brought against or with respect to any such Watson Benefit Plan, except for any of the foregoing which would not have a Watson Material Adverse Effect. All contributions required to be made as of the date 20 hereof to the Watson Benefit Plans have been made or provided for. Since September 25, 1980, neither Watson nor any ERISA Affiliate of Watson (during the period of its affiliated status and prior thereto, to its knowledge) has contributed to, or been required to contribute to, any "multiemployer plan" (as defined in Sections 3(37) and 4001(a)(3) of ERISA). Watson does not maintain or contribute to any plan or arrangement which provides or has any liability to provide life insurance or medical or other employee welfare benefits to any employee or former employee upon his retirement or termination of employment, and Watson has never represented, promised or contracted (whether in oral or written form) to any employee or former employee that such benefits would be provided. The execution of, and performance of the transactions contemplated in, this Agreement will not (either alone or upon the occurrence of any additional or subsequent events) constitute an event under any benefit plan, policy, arrangement or agreement or any trust or loan that will or may result in any payment (whether of severance pay or otherwise), acceleration, forgiveness of indebtedness, vesting, distribution, increase in benefits or obligation to fund benefits with respect to any employee. No Watson Benefit Plan which is an "employee pension plan" within the meaning of Section 3(3) of ERISA has been completely or partially terminated. None of the Watson Benefit Plans has any material unfunded liabilities which are not reflected in the Watson Reports. For purposes of this Agreement "ERISA Affiliate" means any business or entity which is a member of the same "controlled group of corporations," under "common control" or an "affiliated service group" with an entity within the meanings of Sections 414(b), (c) or (m) of the Code, or required to be aggregated with the entity under Section 414(o) of the Code, or is under "common control" with the entity, within the meaning of Section 4001(a)(14) of ERISA, or any regulations promulgated or proposed under any of the foregoing Sections. Section 3.20 Labor Matters. Neither Watson nor any of its Subsidiaries is a party to, or bound by, any collective bargaining agreement, contract or other agreement or understanding with a labor union or labor organization. There is no unfair labor practice or labor arbitration proceeding pending or, to the knowledge of the executive officers of Watson, threatened against Watson or its Subsidiaries relating to their business, except for any such proceeding which would not have a Watson Material Adverse Effect. To the knowledge of the executive officers of Watson, there are no organizational efforts with respect to the formation of a collective bargaining unit presently being made or threatened involving employees of Watson or any of its Subsidiaries. There is no labor strike, dispute, slowdown or work stoppage pending or threatened against Watson or any of its Subsidiaries nor have they experienced any of the same during the last three years. All employees of Watson or any of its Subsidiaries are employed at will. A list of Watson's employees who earned in excess of 21 $100,000 during calendar year 1994 or who Watson reasonably expects will earn in excess of such amount during calendar year 1995, together with such employee's current job title and salary history during the last three years, is described in the Watson Disclosure Letter. Section 3.21. Environmental Matters. There are no Environmental Liabilities of Watson that, individually or in the aggregate, have had or would reasonably be expected to have a Watson Material Adverse Effect. As used in this Agreement, "Environmental Laws" means any and all federal, state, local and foreign statutes, laws, judicial decisions, regulations, ordinances, rules, judgments, orders, decrees, codes, plans, injunctions, permits, concessions, grants, franchises, licenses, agreements and governmental restrictions, whether now or hereafter in effect, relating to human health, the environment or to emissions, discharges or releases of pollutants, contaminants, Hazardous Substances or wastes into the environment, including without limitation, ambient air, surface water, ground water or land, or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of pollutants, contaminants, Hazardous Substances or wastes or the clean-up or other remediation thereof. "Environmental Liabilities" with respect to any Person means any and all liabilities of or relating to such Person or any of its Subsidiaries (including any entity which is, in whole or in part, a predecessor of such Person or any of its Subsidiaries), whether vested or unvested, contingent or fixed, actual or potential, known or unknown, which (a) arise under or relate to matters covered by Environmental Laws; and (b) relate to actions occurring or conditions existing on or prior to the Closing Date. "Hazardous Substances" means any toxic, radioactive, caustic or otherwise hazardous substance, including petroleum, its derivatives, by- products and other hydrocarbons, or any substance having any constituent elements displaying any of the foregoing characteristics, including, without limitation, any substance regulated under Environmental Laws. Section 3.22. Absence of Indemnifiable Claims, etc. There are no losses, claims, damages, costs, expenses, liabilities or judgements which would entitle any director, officer or employee of Watson or any of its Subsidiaries to indemnification by Watson under applicable law, the articles of incorporation or by-laws of Watson or any of its Subsidiaries or any insurance policy maintained by Watson or any of its Subsidiaries. Section 3.23 No Brokers. Watson has not entered into any contract, arrangement or understanding with any person or firm which may result in the obligation of CIRCA or Watson to pay any finder's fee, brokerage or agent's commissions or other like payments in connection with the negotiations leading to this Agreement or the consummation of the transactions contemplated 22 hereby, except that Watson has retained DLJ as its financial advisor, the arrangements with which have been disclosed in writing to CIRCA prior to the date hereof. Other than the foregoing arrangements, Watson is not aware of any claim for payment of any finder's fees, brokerage or agent's commission or other like payments in connection with the negotiations leading to this Agreement or the consummation of the transaction contemplated hereby. Section 3.24 Opinion of Financial Advisor. Watson has received the opinion of Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ"), to the effect that, as of the date hereof, the number of shares of Watson Common Stock to be issued by Watson in the Merger in exchange for each share of CIRCA Common Stock is fair to Watson's stockholders from a financial point of view. Section 3.25 CIRCA Stock Ownership. Neither Watson nor any of its Subsidiaries owns any shares of CIRCA Common Stock or other securities convertible into shares of CIRCA Common Stock. Section 3.26 Watson Common Stock. The issuance and delivery by Watson of shares of Watson Common Stock in connection with the Merger and this Agreement have been duly and validly authorized by all necessary corporate action on the part of Watson. The shares of Watson Common Stock to be issued in connection with the Merger and this Agreement, when issued in accordance with the terms of this Agreement, will be validly issued, fully paid and nonassessable and not subject to preemptive rights of any sort and will, when issued, be registered under the Securities Act, the Exchange Act and registered or exempt from registration under applicable "blue sky laws". Section 3.27 Convertible Securities. Watson has no outstanding options, warrants or other securities exercisable for, or convertible into, shares of Watson Common Stock, the terms of which would require any anti-dilution adjustments by reason of the consummation of the transactions contemplated hereby. Section 3.28 Pooling of Interests, Tax Reorganization. To the knowledge of the executive officers of Watson, neither Watson nor any of its Affiliates has taken or failed to take any action which would prevent the accounting for the Merger as a pooling of interests in accordance with Accounting Principles Board Opinion No. 16, the interpretative releases issued pursuant thereto, and the pronouncements of the SEC. Neither Watson nor any of its Affiliates has taken or failed to take any action which would prevent the Merger from constituting a reorganization within the meaning of section 368(a) of the Code. Section 3.29 Takeover Statutes. No "fair price", "moratorium", "control share acquisition" or other similar antitakeover statute or regulation enacted under state or federal 23 laws in the United States (each a "Takeover Statute"), applicable to Watson or any of its Subsidiaries is applicable to the Merger or the other transactions contemplated hereby.

CIRCA and each of its Subsidiaries (a) have timely filed all material federal, state and foreign tax returns required to be filed by any of them for tax years ended prior to the date of this Agreement or requests for extensions have been timely filed and any such request shall have been granted and not expired, and all such returns are complete and accurate in all material respects; (b) have paid or accrued all taxes shown to be due and payable on such returns; (c) have properly accrued all such taxes for such periods subsequent to the periods covered by such returns; and (d) have "open" years for federal income tax returns only as set forth in the CIRCA Disclosure Letter. Section 4.19 Employee Benefit Plans. All employee benefit plans and other benefit arrangements covering employees of CIRCA and the CIRCA Subsidiaries (the "CIRCA Benefit Plans") and all employee agreements providing compensation, severance or other benefits to any employee or former employee of CIRCA or any of the CIRCA Subsidiaries are set forth in the CIRCA Disclosure Letter. True and complete copies of all CIRCA Benefit Plans, including any related trust or funding vehicles, policies or contracts, have been made available to Watson. To the extent applicable, the CIRCA Benefit Plans comply, in all material respects, with the requirements of ERISA and the Code, and any CIRCA Benefit Plan intended to be qualified under Section 401(a) of the Code has been determined by the IRS to be so qualified and has been timely amended and filed with the IRS with respect to changes required by the Tax Reform Act of 1986 and subsequent legislation. Neither CIRCA nor any ERISA Affiliate of CIRCA (during the period of its affiliated status and prior thereto, to its knowledge) maintains, contributes to or has in the past maintained or contributed to any 33 benefit plan which is covered by Title IV of ERISA or Section 412 of the Code. CIRCA or any CIRCA Benefit Plan have not incurred any liability or penalty under, and the executive officers of CIRCA do not know of any instance that CIRCA or any CIRCA Benefit Plan may incur any liability or penalty under, Section 4975 of the Code or Section 502(i) of ERISA. Each CIRCA Benefit Plan has been maintained and administered in all material respects in compliance with its terms and with ERISA and the Code to the extent applicable thereto. To the knowledge of the executive officers of CIRCA, there are no pending or anticipated material claims against or otherwise involving any of the CIRCA Benefit Plans and no suit, action or other litigation (excluding claims for benefits incurred in the ordinary course of CIRCA Benefit Plan activities) has been brought against or with respect to any such CIRCA Benefit Plan, except for any of the foregoing which would not have a CIRCA Material Adverse Effect. All contributions required to be made as of the date hereof to the CIRCA Benefit Plans have been made or provided for. Since September 25, 1980, neither CIRCA nor any ERISA Affiliate of CIRCA (during the period of its affiliated status and prior thereto, to its knowledge) has contributed to, or been required to contribute to, any "multiemployer plan" (as defined in Sections 3(37) and 4001(a)(3) of ERISA). CIRCA does not maintain or contribute to any plan or arrangement which provides or has any liability to provide life insurance or medical or other employee welfare benefits to any employee or former employee upon his retirement or termination of employment, and CIRCA has never represented, promised or contracted (whether in oral or written form) to any employee or former employee that such benefits would be provided. The execution of, and performance of the transactions contemplated in, this Agreement will not (either alone or upon the occurrence of any additional or subsequent events) constitute an event under any benefit plan, policy, arrangement or agreement or any trust or loan that will or may result in any payment (whether of severance pay or otherwise), acceleration, forgiveness of indebtedness, vesting, distribution, increase in benefits or obligation to fund benefits with respect to any employee. No CIRCA Benefit Plan which is an "employee pension plan" within the meaning of Section 3(3) of ERISA has been completely or partially terminated. None of the CIRCA Benefit Plans has any material unfunded liabilities which are not reflected in the CIRCA Reports. Section 4.20 Labor Matters. Neither CIRCA nor any of its Subsidiaries is a party to, or bound by, any collective bargaining agreement, contract or other agreement or understanding with a labor union or labor organization. There is no unfair labor practice or labor arbitration proceeding pending or, to the knowledge of the executive officers of CIRCA, threatened against CIRCA or its Subsidiaries relating to their business, except for any such proceeding which would not have a CIRCA Material Adverse Effect. To the knowledge of the executive officers of CIRCA, there are no organizational efforts with respect to the formation of a collective bargaining unit presently being made or threatened 34 involving employees of CIRCA or any of its Subsidiaries. There is no labor strike, dispute, slowdown or work stoppage pending or threatened against CIRCA or any of its Subsidiaries nor have they experienced any of the same during the last three years. All employees of CIRCA or any of its Subsidiaries are employed at will. A list of CIRCA's employees who earned in excess of $100,000 during calendar year 1994 or who CIRCA reasonably expects will earn in excess of such amount during calendar year 1995, together with such employee's current job title and salary history during the last three years, is described in the CIRCA Disclosure Letter. Section 4.21 Environmental Matters. There are no Environmental Liabilities of CIRCA that, individually or in the aggregate, have had or would reasonably be expected to have a CIRCA Material Adverse Effect. Section 4.22 Takeover Statutes. No Takeover Statute applicable to CIRCA or any of its Subsidiaries is applicable to the Merger or the other transactions contemplated hereby. Section 4.23 Absence of Indemnifiable Claims, etc. There are no losses, claims, damages, costs, expenses, liabilities or judgements which would entitle any director, officer or employee of CIRCA or any of its Subsidiaries to indemnification by CIRCA under applicable law, the articles of incorporation or by-laws of CIRCA or any of its Subsidiaries or any insurance policy maintained by CIRCA or any of its Subsidiaries. Section 4.24 No Brokers. CIRCA has not entered into any contract, arrangement or understanding with any person or firm which may result in the obligation of CIRCA or Watson to pay any finder's fee, brokerage or agent's commissions or other like payments in connection with the negotiations leading to this Agreement or the consummation of the transactions contemplated hereby, except that CIRCA has retained Bear Stearns & Co. Inc. ("Bear Stearns") and Wertheim Schroder & Co. Incorporated ("Wertheim Schroder") as its financial advisors, the arrangements with which have been disclosed in writing to Watson prior to the date hereof. Other than the foregoing arrangements, CIRCA is not aware of any claim for payment of any finder's fees, brokerage or agent's commission or other like payments in connection with the negotiations leading to this Agreement or the consummation of the transaction contemplated hereby. Section 4.25 Opinion of Financial Advisors. CIRCA has received the opinions of Bear Stearns and Wertheim Schroder to the effect that, as of the date hereof, the Merger or the Exchange Ratio, as the case may be, is fair to the holders of CIRCA Common Stock from a financial point of view. 35 Section 4.26 Watson Stock Ownership. Neither CIRCA nor any of its Subsidiaries owns any shares of Watson Common Stock or other securities convertible into Watson Common Stock. Section 4.27 Pooling of Interests, Tax Reorganization. To the knowledge of the executive officers of CIRCA, neither CIRCA nor any of its Affiliates has taken or failed to take any action which would prevent the accounting for the Merger as a pooling of interests in accordance with Accounting Principles Board Opinion No. 16, the interpretative releases issued pursuant thereto, and the pronouncements of the SEC. Neither CIRCA nor any of its Affiliates has not taken or failed to take any action which would prevent the Merger from constituting a reorganization within the meaning of section 368(a) of the Code. ARTICLE V COVENANTS Section 5.1 Alternative Proposals. Prior to the Effective Time, Watson and CIRCA each agree (a) that neither it nor any of its Subsidiaries shall, and it shall direct and cause its officers, directors, employees, agents and representatives (including, without limitation, any investment banker, attorney or accountant retained by it or any of its Subsidiaries) not to, initiate, solicit or encourage, directly or indirectly, any inquiries or the making or implementation of any proposal or offer (including, without limitation, any proposal or offer to its stockholders) with respect to a merger, acquisition, consolidation or similar transaction involving, or any purchase of all or any significant portion of the assets or any equity securities of, Watson or CIRCA, as the case may be, or any of its respective Subsidiaries (any such proposal or offer being hereinafter referred to as an "Alternative Proposal") or engage in any negotiations concerning, or provide any confidential information or data to, or have any discussions with, any person relating to an Alternative Proposal, or otherwise facilitate any effort or attempt to make or implement an Alternative Proposal; (b) that it will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any parties conducted heretofore with respect to any of the foregoing, and it will take the necessary steps to inform the individuals or entities referred to above of the obligations undertaken in this Section 5.1; and (c) that it will notify the other immediately if any such inquiries or proposals are received by, any such information is requested from, or any such negotiations or discussions are sought to be initiated or continued with, it; provided, however, that nothing contained in this Section 5.1 shall prohibit the Board of Directors of CIRCA or Watson, as the case may be, from (A) furnishing information to or entering into discussions or negotiations with, any person or entity that makes an unsolicited bona fide proposal to acquire CIRCA or Watson, 36 as the case may be, pursuant to a merger, consolidation, share exchange, purchase of a substantial portion of assets, business combination or other similar transaction, if, and only to the extent that, (i) the Board of Directors of CIRCA or Watson, as the case may be, determines in good faith that such action is required for the Board of Directors to comply with its fiduciary duties to stockholders imposed by law; (ii) prior to furnishing such information to, or entering into discussions or negotiations with, such person or entity, CIRCA or Watson, as the case may be, provides written notice to the other to the effect that it is furnishing information to, or entering into discussions or negotiations with, such person or entity; and (iii) subject to any confidentiality agreement with such person or entity (which CIRCA or Watson, as the case may be, determined in good faith was required to be executed in order for its Board of Directors to comply with its fiduciary duties to stockholders imposed by law), CIRCA or Watson, as the case may be, keeps the other informed of the status of any such discussions or negotiations; and (B) to the extent applicable, complying with Rule 14e-2 promulgated under the Exchange Act with regard to an Alternative Proposal. Nothing in this Section 5.1 shall (x) permit CIRCA or Watson to terminate this Agreement (except as specifically provided in Article 7 hereof); (y) permit CIRCA to enter into any agreement with respect to an Alternative Proposal during the term of this Agreement (it being agreed that during the term of this Agreement, CIRCA shall not enter into any agreement with any person that provides for, or in any way facilitates, an Alternative Proposal (other than a confidentiality agreement in customary form)); or (z) affect any other obligation of CIRCA or Watson under this Agreement. Section 5.2 Interim Operations. Prior to the Effective Time, except as set forth in the their respective Disclosure Letters or as contemplated by any other provision of this Agreement, unless the other party has consented in writing thereto, each of CIRCA and Watson: (i) Shall, and shall cause each of its Subsidiaries to, conduct its operations according to their usual, regular and ordinary course in substantially the same manner as heretofore conducted;

Section 5.3 Meetings of Stockholders. Each of Watson and CIRCA will take all action necessary in accordance with applicable law and their respective Certificates of Incorporation and Bylaws to convene a meeting of their respective stockholders as promptly as practicable to consider and vote upon (a) in the case of Watson, (i) the approval of the Merger, this Agreement and the transactions 39 contemplated hereby (to the extent required by applicable law) and the issuance of the shares of Watson Common Stock pursuant to the Merger contemplated hereby; and (ii) the approval of an amendment to Watson's Certificate of Incorporation to (A) increase the maximum number of authorized shares of Watson Common Stock and (B) create three classes of directors consisting of three persons in each class; and (b) in the case of CIRCA, the approval of the Merger, this Agreement and the transactions contemplated hereby. Each such meeting shall be held on the same day. The Board of Directors of each of Watson and CIRCA shall recommend such approval and Watson and CIRCA shall each take all lawful action to solicit such approval, including, without limitation, timely mailing the Proxy Statement to their respective stockholders; provided, however, that such recommendation or solicitation is subject to any action (including any withdrawal or change of its recommendation) taken by, or upon authority of, the Board of Directors of Watson or CIRCA, as the case may be, in the exercise of its good faith judgment as to its fiduciary duties to its stockholders imposed by law. It shall be a condition to the mailing of the Proxy Statement that (x) Watson shall have received a "comfort" letter from Coopers & Lybrand, independent public accountants for CIRCA, dated the date of the Proxy Statement, with respect to the financial statements of CIRCA included in the Proxy Statement, substantially in the form described in Section 6.3(e) and CIRCA shall use its reasonable best efforts to obtain such letter; and (y) CIRCA shall have received a "comfort" letter from Price Waterhouse, independent public accountants for Watson, dated the date of the Proxy Statement, with respect to the financial statements of Watson included in the Proxy Statement, substantially in the form described in Section 6.2(e) and Watson shall use its reasonable best efforts to obtain such letter. Section 5\C Filings; Other Action. (a) Subject to the terms and conditions herein provided, CIRCA and Watson shall: (a) promptly make their respective filings and thereafter make any other required submissions under the HSR Act with respect to the Merger; (b) use all reasonable efforts to cooperate with one another in (i) determining which filings are required to be made prior to the Effective Time with, and which consents, approvals, permits or authorizations are required to be obtained prior to the Effective Time from, governmental or regulatory authorities of the United States, the several states and foreign jurisdictions in connection with the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby; and (ii) timely making all such filings and timely seeking all such consents, approvals, permits or authorizations; and (c) use all reasonable efforts to take, or cause to be taken, all other action and do, or cause to be done, all other things necessary, proper or appropriate to consummate and make effective the transactions contemplated by this Agreement. If, at any time after the Effective Time, any further reasonable 40 action is necessary or desirable to carry out the purpose of this Agreement, the proper officers and directors of Watson and CIRCA shall take all such necessary action. (b) (i) CIRCA and Watson shall give any notices to third parties, and use all reasonable efforts to obtain any third party consents, (A) necessary, proper or advisable to consummate the transactions contemplated in this Agreement or (B) disclosed or required to be disclosed in the Watson Disclosure Letter or the CIRCA Disclosure Letter, as the case may be. (ii) In the event that either party shall fail to obtain any third party consent described in subsection (b)(i) above, such party shall use all reasonable efforts, and shall take any such actions reasonably requested by the other party hereto, to minimize any adverse effect upon CIRCA and Watson, their respective Subsidiaries, and their respective businesses resulting, or which could reasonably be expected to result after the Effective Time, from the failure to obtain such consent. (c) From the date of this Agreement until the Effective Time, Watson and CIRCA shall each promptly notify the other in writing of any pending or, to its knowledge, threatened action, proceeding or investigation by any governmental entity or any other person (i) challenging or seeking material damages in connection with the Merger or (ii) seeking to restrain or prohibit the consummation of the Merger, which in either case is reasonably likely to have a Watson Material Adverse Effect or a CIRCA Material Adverse Effect. (d) From and after the date of this Agreement until the Effective Time, each party hereto shall promptly notify the other of (i) the occurrence, or non-occurrence, of any event the occurrence, or non-occurrence, of which would be likely to cause any condition to the obligations of any party to effect the Merger and the other transactions contemplated by this Agreement not to be satisfied, or (ii) the failure of Watson or CIRCA, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it pursuant to this Agreement which would be likely to result in any condition to the obligations of any party to effect the Merger and the other transactions contemplated by this Agreement not to be satisfied; provided, however, that the delivery of any notice pursuant hereto shall not cure any breach of any representation or warranty requiring disclosure of such matter prior to the date of this Agreement or otherwise limit or affect the remedies available hereunder to the party receiving such notice. Section 5.5 Inspection of Records. From the date hereof to the Effective Time, each of CIRCA and Watson shall (a) allow all designated officers, attorneys, accountants and other representatives of the other reasonable access at all reasonable times to the offices, records and files, correspondence, audits and 41 properties, as well as to all information relating to commitments, contracts, titles and financial position, or otherwise pertaining to the business and affairs, of CIRCA and Watson and their respective Subsidiaries, as the case may be; (b) furnish to the other, the other's counsel, financial advisors, auditors and other authorized representatives such financial and operating data and other information as such persons may reasonably request; and (c) instruct the employees, counsel and financial advisors of CIRCA or Watson, as the case may be, to cooperate with the other in the other's investigation of the business of it and its Subsidiaries. All information disclosed by a party hereto to the other party hereto and their respective representatives shall be subject to the terms of that certain Non-Disclosure Agreement (the "Confidentiality Agreement") dated as of February 16, 1995 between Watson and CIRCA. Notwithstanding the foregoing, Watson shall not have access to the proprietary scientific data of the Subsidiary of CIRCA listed in Section 5.5 of the CIRCA Disclosure Letter. Section 5.6 Publicity. Neither party hereto shall make any press release or public announcement with respect to this Agreement, the Merger or the transaction contemplated hereby without the prior written consent of the other party hereto (which consent shall not be unreasonably withheld); provided, however, that each party hereto may make any disclosure or announcement which such party, in the opinion of its legal counsel, is obligated to make pursuant to applicable law or regulation of any national securities exchange, in which case, the party desiring to make the disclosure shall consult with the other party hereto prior to making such disclosure or announcement. Section 5.7 Registration Statement. Watson and CIRCA shall cooperate and promptly prepare and Watson shall file with the SEC as soon as practicable a Registration Statement on Form S-4 (the "Form S-4") under the Securities Act, with respect to the Watson Common Stock issuable in the Merger, a portion of which Registration Statement shall also serve as the Proxy Statement. The respective parties will cause the Proxy Statement and the Form S-4 to comply as to form in all material respects with the applicable provisions of the Securities Act, the Exchange Act and the rules and regulations promulgated thereunder. Watson shall use all reasonable efforts, and CIRCA will cooperate with Watson, to have the Form S-4 declared effective by the SEC as promptly as practicable. Watson shall use its best efforts to obtain, prior to the effective date of the Form S-4, all necessary state securities law or "Blue Sky" permits or approvals required to carry out the transactions contemplated by this Agreement and will pay all expenses incident thereto. No amendment or supplement to the Proxy Statement will be made by Watson or CIRCA without the approval of the other party. Watson will advise CIRCA, promptly after it receives notice thereof, of the time when the Form S-4 has become effective or any supplement or amendment has been filed, the issuance of any stop order, the suspension of the qualification of 42 the Watson Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction, or any request by the SEC for amendment of the Proxy Statement or the Form S-4 or comments thereon and responses thereto or requests by the SEC for additional information. Section 5.8 Further Action. Each party hereto shall, subject to the fulfillment at or before the Effective Time of each of the conditions of performance set forth herein or the waiver thereof, perform such further acts and execute such documents as may be reasonably required to effect the Merger. Section 5.9 Affiliate Letters. At least 30 days prior to the Closing Date, CIRCA shall deliver to Watson a list of names and addresses of those persons who were, in CIRCA's reasonable judgment, at the record date for its stockholders' meeting to approve the Merger, "affiliates" (each such person, an "Affiliate") of CIRCA within the meaning of Rule 145 of the rules and regulations promulgated under the Securities Act. CIRCA shall provide Watson such information and documents as Watson shall reasonably request for purposes of reviewing such list. CIRCA shall deliver or cause to be delivered to Watson, prior to the Closing Date, from each of the Affiliates of CIRCA identified in the foregoing list, an Affiliate Letter in the form attached hereto as Exhibit A. Watson shall be entitled to place legends as specified in such Affiliate Letters on the certificates evidencing any Watson Common Stock to be received by such Affiliates pursuant to the terms of this Agreement, and to issue appropriate stop transfer instructions to the transfer agent for the Watson Common Stock, consistent with the terms of such Affiliate Letters. Section 5.10 Expenses. Whether or not the Merger is consummated, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such expenses except as expressly provided herein and except that (a) the filing fee in connection with the HSR Act filing; (b) the filing fee in connection with the filing of the Form S-4 or Proxy Statement with the SEC; (c) the filing fees in connection with "blue sky" compliance; and (d) the expenses incurred in connection with preparing, printing and mailing the Form S-4 and the Proxy Statement, shall be shared equally by CIRCA and Watson. Section 5.11 Insurance; Indemnity. (a) From the Effective Time through the six year anniversary of the Effective Time, Watson shall indemnify, defend and hold harmless, to the fullest extent permitted under applicable law, each person who is now, or has been at any time prior to the date hereof, an officer, director, employee, trustee or agent of CIRCA (or any Subsidiary or division thereof), including, without limitation, each person controlling any of the foregoing persons (individually, an "Indemnified Party" and collectively, the "Indemnified Parties"), against all losses, 43 claims, damages, liabilities, costs or expenses (including attorneys' fees), judgments, fines, penalties and amounts paid in settlement in connection with any claim, action, suit, proceeding or investigation arising out of or pertaining to acts or omissions, or alleged acts or omissions, by them in their capacities as such, whether commenced, asserted or claimed before or after the Effective Time and including, without limitation, liabilities arising under the Securities Act, the Exchange Act and state corporation laws in connection with the Merger. In the event of any such claim, action, suit, proceeding or investigation (an "Action"), (i) Watson shall pay the reasonable fees and expenses of counsel selected by the Indemnified Party, which counsel shall be reasonably acceptable to Watson, in advance of the final disposition of any such Action to the full extent permitted by applicable law; provided, however, that Watson shall have no obligation under this clause (i) unless Watson has received an undertaking from the Indemnified Party to promptly return any amounts paid by Watson or its Subsidiaries in the event that it shall ultimately have been determined by a court of competent jurisdiction not subject to further appeal that the Indemnified Party is not entitled to be indemnified under applicable law; and (ii) Watson and the Surviving Corporation will cooperate in the defense of any such matter; provided, however, that Watson shall not be liable for any settlement effected without its written consent (which consent shall not be unreasonably withheld) and provided, further, that Watson shall not be obligated pursuant to this Section to pay the fees and disbursements of more than one counsel for all Indemnified Parties in any single Action except to the extent that, in the opinion of counsel for the Indemnified Parties, two or more of such Indemnified Parties have conflicting interests in the outcome of such action. All rights to indemnification in respect of any Action made or asserted prior to the sixth anniversary of the Effective Time shall continue until final disposition of such Action. (b) Watson shall cause the Surviving Corporation to keep in effect provisions in its Certificate of Incorporation and Bylaws providing for exculpation of director and officer liability and its indemnification of the Indemnified Parties to the fullest extent permitted under applicable law, which provisions shall not be amended except as required by applicable law or except to make changes permitted by law that would enlarge the Indemnified Parties' right of indemnification. (c) Without in any way limiting any of Watson's other obligations under this Section 5.11 or any other rights to indemnity available, Watson shall use its best efforts to cause to be maintained in effect for not less than two years after the Effective Time, the current policies of directors' and officers' liability insurance and fiduciary liability insurance maintained by CIRCA with respect to matters occurring prior to the Effective Time; provided, however, that (i) Watson may substitute therefor 44 policies of substantially the same coverage containing terms and conditions which are substantially the same for the Indemnified Parties to the extent reasonably available and (ii) Watson shall not be required to pay an annual premium for such insurance in excess of 150% of the last annual premium paid prior to the date hereof, but in such case shall purchase as much coverage as possible for such amount. Section 5.12 Restructuring of Merger. Upon the mutual agreement of Watson and CIRCA, the Merger shall be restructured in the form of a forward subsidiary merger of CIRCA into Merger Sub, with Merger Sub being the surviving corporation, or as a merger of CIRCA into Watson, with Watson being the surviving corporation. In such event, this Agreement shall be deemed appropriately modified to reflect such form of merger and CIRCA and Watson may each update their respective Disclosure Letters to reflect any breach of a representation or warranty resulting from such restructuring. Section 5.13 Rights Agreement. CIRCA shall take all necessary action prior to the Effective Time to cause the dilution provisions of that certain Stockholder Protection Rights Agreement dated as of November 1, 1991, between CIRCA and American Stock Transfer & Trust Company, as Rights Agent, to be inapplicable to the Merger, without any payment to holders of rights issued pursuant to such Rights Agreement. Section 5.14 Governance. (a) Watson shall take such action as may be necessary (including, to the extent necessary, obtaining resignations of its directors) so that the persons listed on Schedule 5.14 of the Watson Disclosure Letter constitute the entire board of directors of Watson at the Effective Time, with terms expiring as stated on such Schedule. If, prior to the Effective Time, any of such persons shall decline or be unable to serve, a replacement shall be designated in accordance with such Schedule. (b) Dr. Allen Chao shall continue to be Chief Executive Officer of Watson at the Effective Time and Dr. Alec Keith shall continue to be Chairman of Watson at the Effective Time. The Board of Directors of Watson shall take all necessary action to cause Dr. Mel Sharoky to be elected as President of Watson at the Effective Time. Section 5.15 Pooling; Reorganization. From and after the date hereof and until the Effective Time, neither Watson nor CIRCA nor any of their respective Subsidiaries or other affiliates shall (a) knowingly take any action, or knowingly fail to take any action, that would jeopardize the treatment of the Merger as a "pooling of interests" for accounting purposes; (b) knowingly take any action, or knowingly fail to take any action, that would jeopardize qualification of the Merger as a reorganization within the meaning of Section 368(a) of the Code; or (c) enter into any contract, agreement, commitment or arrangement with respect to 45 either of the foregoing. Following the Effective Time, Watson shall use its best efforts to conduct its business in a manner that would not jeopardize the characterization of the Merger as a "pooling of interests" for accounting purposes and as a reorganization within the meaning of Section 368(a) of the Code. Section 5.16 Employee Benefit Plans. As soon as practicable after the Closing Date but in no event later than January 1, 1996, Watson shall provide benefits to employees of CIRCA and its Subsidiaries which are substantially similar to the benefits provided to similarly situated employees of Watson and its Subsidiaries. The date(s) on which employees of CIRCA and its Subsidiaries are provided benefits pursuant to the preceding sentence shall be referred to as the "Benefit Plan Transition Dates." Subject to the requirements of applicable law, after the Closing Date, Watson shall cause the Surviving Corporation to maintain the CIRCA Benefit Plans in substantially the same form as in effect on the date of this Agreement until the applicable Benefit Plan Transition Date. Subject to the requirements of applicable law, after the Effective Time, Watson shall provide benefits to employees of CIRCA and its Subsidiaries which are substantially similar to the benefits provided to similarly situated employees of Watson and its Subsidiaries.

Watson acknowledges that the agreements contained in this Section 7.5(b) are an integral part of the transactions contemplated by 53 this Agreement, and that, without these agreements, CIRCA would not enter into this Agreement. Accordingly, if Watson fails to promptly pay the amount due pursuant to this Section 7.5(b), and, in order to obtain such payment, CIRCA commences a suit which results in a final, non-appealable judgment against Watson for the fee set forth in this Section 7.5(b), Watson shall pay to CIRCA its costs and expenses (including attorneys' fees) incurred by CIRCA in connection with such suit, together with interest on the amount of the fee at the rate of 12% per annum.

(Nasdaq: WATS) and Circa Pharmaceuticals Inc. (AMEX: RXC) today announced that they have entered into a definitive merger agreement under which Circa will merge with a wholly owned subsidiary of Watson through an exchange of 0.86 shares of Watson for each share of Circa. Watson Pharmaceuticals will become the parent company of Circa following the merger. The merger is expected to be accretive to Watson's 1995 per share earnings. Allen Chao, Ph.D., president and chief executive officer of Watson Pharmaceuticals stated, "Watson has a balanced strategy of focusing on the development, production and marketing of off- patent pharmaceutical products and proprietary drugs. This merger with Circa is an important step in furthering this strategy and positions the company for continued strong growth. "The merged companies will provide a revenue stream and product pipeline including niche off-patent pharmaceutical products, proprietary products, OTC products, income for the 50 percent ownership of Somerset Pharmaceuticals and royalty income from Dilacor XR. Our revenue stream and product pipeline immediately will become more diversified and proprietary," continued Dr. Chao. "Dr. Sharoky, with his experience in new drug development, will enhance the company's capabilities in expediting our development programs for proprietary products. We also gain critical mass through a combined cash balance of approximately $100 million and a virtually debt free balance sheet," concluded Dr. Chao. Melvin Sharoky, M.D., chief executive officer of Circa, added, "Our combination with Watson allows Circa's shareholders to immediately benefit from Watson's established presence in off- patent pharmaceuticals. The two companies complement each other technologically in the area of drug delivery systems with Watson's polymer-based drug delivery technology and Circa's gum technology." In 1994, Watson generated $87.1 million in revenue and $18.7 million in net income, or $1.05 per share. Circa's 1994 earnings were $17.3 million, or $0.79 per share. Currently, Watson manufactures a total of 62 dosage strengths representing 20 ethical drugs. Additionally, Watson has a total of seven Abbreviated New Drug Applications (ANDAs) pending at the Food and Drug Administration (FDA). Circa has a 50 percent interest in Somerset Pharmaceuticals which markets Eldepryl(R), used in the treatment of Parkinson's disease. Eldepryl(R) sales were $125 million in 1994. The Somerset pipeline includes an Eldepryl(R) transdermal patch in development for several neurological indications, as well as ipriflavone which is indicated for the treatment of osteoporosis. Circa receives a 20 percent royalty on the sales of Dilacor(TM) XR, marketed by Rhone-Poulenc Rorer Inc. for hypertension and angina. Dilacor(TM) XR sales were $128 million in 1994. The company's 20 percent royalty for 1995 and 1996 increases to 22 percent in 1997 through the year 2000. In addition, Circa has focused on sustained release and gum delivery systems, as well as proprietary product development. Under the proposed agreement, following the merger the Watson Pharmaceuticals board will be comprised of nine members including five current Watson board members, three current Circa board members and one member to be selected by Circa and approved by Watson. Dr. Sharoky will become the president of Watson, with responsibility for research and development, business development and the acquisition of new products. Dr. Chao will remain chief executive officer. The boards of directors of both companies have approved the transaction. The proposed transaction is subject to shareholder approval of both companies and may be terminated under certain circumstances including the trading of Watson common stock below an average price of $25 per share for the 20 business days ending prior to the 13th business day before the Shareholders' meetings, subject to Watson's right to increase the exchange ration. The merger is expected to be tax-free and will be accounted for as a pooling of interests. Circa has 21.7 million shares outstanding and Watson has 17.8 million shares outstanding. Circa Pharmaceuticals Inc., headquartered in Copiague, N.Y., manufactures and sells solid dosage prescription and over-the counter pharmaceuticals. Watson Pharmaceuticals Inc., headquartered in Corona, is engaged in the manufacture and sale of off-patent medications and the development of advanced drug delivery systems.
