Item 5.  Other Events.
         -------------

         On December 24, 1996 Watson Pharmaceuticals, Inc. (the "Registrant")
entered into a definitive Agreement and Plan of Merger by and among Royce
Laboratories, Inc. ("Royce"), Dolphins Acquisition Corp., a wholly-owned
subsidiary of the Registrant ("Dolphins"), and the Registrant (the "Merger
Agreement"), pursuant to which Dolphins will merge (the "Merger") with and into
Royce, with Royce being the surviving corporation in the Merger.  Immediately
after the Merger, Royce will become the wholly-owned subsidiary of the
Registrant.  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, Royce shareholders will receive common shares of
Watson worth the equivalent of $7.25 for each share of Royce, subject to a
collar on Watson's stock price of $38 to $47 per share.  
    

   

         The Registrant has been advised that due to pooling of interest
considerations, it will not be possible for the holders of small numbers of
shares of Royce Common Stock to receive cash in lieu of shares of Watson Common
Stock in connection with the Merger. Therefore, the only cash that will be paid
to Royce shareholders in connection with the Merger will be cash in lieu of
fractional shares. The Registrant and Royce are having discussions with their
respective accountants regarding the possibility of paying cash to holders of
small numbers of shares of Royce Common Stock in lieu of shares of Watson Common
Stock while retaining the pooling of interest treatment for the Merger. No
assurance can be given that the Registrant and Royce will be successful in this
regard.

    

         Consummation of the Merger is subject to the satisfaction of certain
conditions, including, without limitation, approval by Royce's stockholders of
the Merger Agreement, regulatory approvals and treatment of the Merger as a
"pooling of interests" for accounting purposes.  A copy of the Merger Agreement
is attached as Exhibit 10.1 and is hereby incorporated by reference.

         A copy of the joint press release of the Registrant and Royce, dated
December 26, 1996, is attached as Exhibit 10.2 and is hereby incorporated by
reference.

                                  Exhibit 10.1

                          AGREEMENT AND PLAN OF MERGER

         THIS AGREEMENT AND PLAN OF MERGER is dated as of December 24, 1996
(the "Agreement") by and among Watson Pharmaceuticals, Inc., a Nevada
corporation ("Watson"), Dolphins Acquisition Corp., a Florida corporation and
the wholly-owned subsidiary of Watson ("Watson Sub"), and Royce Laboratories,
Inc., a Florida corporation (the "Company").

         WHEREAS, the Board of Directors of each of Watson and the Company have
determined that a business combination between Watson and the Company merging
their respective pharmaceutical businesses is in the best interests of their
respective companies and stockholders and accordingly have agreed to effect the
merger provided for herein upon the terms and subject to the conditions set
forth herein; and

         WHEREAS, it is the intention of the parties to this Agreement that (a)
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 (b) for accounting purposes, the
merger provided for herein shall qualify as a "pooling of interests"; and

         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

         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), Watson Sub shall be merged with and into the Company in accordance
with the laws of the State of Florida and the terms of this Agreement (the
"Merger"), whereupon the separate corporate existence of Watson Sub shall
cease, and the Company shall be the surviving corporation of the Merger (the
Company, as the surviving corporation after the Merger is sometimes referred to
herein as the "Surviving Corporation").

         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, Chicago, Illinois 60602 at 10:00
a.m. three business days 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."





                                       5
<PAGE>   2
         1.3. Effective Time.  If 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 a certificate of merger (the "Certificate of Merger")
to be properly executed and filed in accordance with the laws of the State of
Florida and the terms of this Agreement on or before the Closing Date.  The
parties hereto shall also take such further actions as may be required under the
laws of the State of Florida in connection with the consummation of the Merger.
The Merger shall become effective at such time as the Certificate of Merger is
duly filed with the Secretary of State of Florida or at such later time as is
specified in the Certificate 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 and duties of the Company and Watson Sub, all as provided under
applicable law.

         1.4. Conversion of Shares.

         (a)       At the Effective Time:

                   (i) each share of Common Stock, par value $0.01 per share, 
              of Watson Sub outstanding at the Effective Time, by virtue of the
              Merger and without any action on the part of the holders thereof,
              shall be converted into and exchanged for one share of Common
              Stock, par value $0.01 per share, of the Surviving Corporation;
              and

                   (ii) each share of Common Stock, $0.005 par value per 
              share, of the Company (the "Company Common Stock") outstanding at
              the Effective Time, by virtue of the Merger and without any action
              on the part of the holders thereof, except as otherwise provided
              in Sections 1.4(c) and 1.4(e) hereof, shall be converted into the
              right to receive the number of shares of Watson Common Stock equal
              to the following: $7.25 divided by the Average Closing Price (as
              defined herein) (the "Exchange Ratio").

              (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 Company Common
Stock shall cease to be outstanding and shall be canceled and retired and shall
cease to exist, and each holder of shares of Company Common Stock shall
thereafter cease to have any rights with respect to such shares of Company
Common Stock, except for the right to receive, without interest, the
consideration set forth in this Section 1.4 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
Company Common Stock in accordance with the provisions of this Article I.

              (c)   Each share of Company Common Stock and each share of Series 
A, B, C, D or E Preferred Stock of the Company (collectively, the "Preferred
Stock") held by the Company as treasury stock or owned by Watson or any
Subsidiary (as defined in Section 1.4(d) of this Agreement) of Watson at the
Effective Time shall be canceled, and no payment shall be made with respect
thereto.





                                       6

<PAGE>   3
         (d)   For purposes of this Agreement, (i) the term "Average Closing
Price" shall mean the average of the per share last daily closing price of
Watson Common Stock as quoted on the Nasdaq National Market ("Nasdaq") (and as
reported by The Wall Street Journal or, if not reported thereby, by another
authoritative source) during the ten (10) consecutive trading days ending on the
trading day immediately preceding the Closing Date; provided, however, that (A)
if the Average Closing Price is greater than $47, for purposes of this
Agreement, the Average Closing Price shall be deemed to be equal to $47; and (B)
if the Average Closing Price is less than $38, for purposes of this Agreement,
the Average Closing Price shall be deemed to be equal to $38; (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
fifty percent (50%) 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; and (iii) the word "Person" means an individual, a
corporation, a limited liability company, 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.

         (e)   As soon as practicable after the date hereof, the parties
hereto will negotiate in good faith to enter into an agreement to allow Watson
to pay cash to certain holders of small numbers of shares of Company Common
Stock in lieu of the consideration to be received by such holders of Company
Common Stock pursuant to Section 1.4(a) hereof; provided, however, that the
aggregate cash consideration to be paid to such holders may not exceed 9.9% of
the aggregate consideration to be paid to all holders of Company Common Stock
upon consummation of the transactions contemplated hereby.

         1.5.  Stock Options.  All options and warrants to acquire Company
Common Stock (individually, a "Company Option" and collectively, the "Company
Options") outstanding at the Effective Time under the Company's 1992 Stock
Option Plan, the Company's 1995 Stock Option Plan or otherwise (the "Company
Stock Option Plans") shall remain outstanding following the Effective Time.  At
the Effective Time, such Company Options, by virtue of the Merger and without
any further action on the part of the Company or the holder of such Company
Options, shall 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 Company Options, would be such a
corporation (or a parent or a subsidiary corporation of such corporation) were
Section 424 applicable to such option.  Each Company Option assumed by Watson
shall be exercisable upon





                                       7

<PAGE>   4
the same terms and conditions as under the applicable Company Stock Option Plan
and the applicable option agreement issued thereunder, except that (x) the
unexercised portion of each such Company Option shall be exercisable for that
whole number of shares of Watson Common Stock (rounded to the nearest whole
share, with 0.5 rounded upward) equal to the number of shares of Company Common
Stock subject to the unexercised portion of such Company Option multiplied by
the Exchange Ratio; and (y) the option exercise price per share of Watson
Common Stock shall be an amount equal to the option exercise price per share of
Company Common Stock subject to such Company Option in effect at the Effective
Time divided by the Exchange Ratio (the option price per share, as so
determined, being rounded to the nearest full cent, with $0.005 rounded
upward).  No payment shall be made for fractional interests.  The term,
exercisability, vesting schedule, status as an "incentive stock option" under
Section 422 of the Code, if applicable, and all of the other terms of the
Company Options shall otherwise remain unchanged unless modified by or as a
result of the transaction contemplated by this Agreement.  As soon as
practicable after the Effective Time, Watson shall deliver to the holders of
Company Options appropriate notices setting forth such holders' rights pursuant
to such Company Options, as amended by this Section 1.5 as well as notice of
Watson's assumption of the Company's obligations with respect thereto (which
occurs by virtue of this Agreement).  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 Company Options after
the Effective Time.

         1.6.  Exchange of Certificates Representing Company Common Stock.

         (a)   American Stock Transfer & Trust Company shall act as exchange
agent (the "Exchange Agent") in the Merger.

         (b)   As of the Effective Time and in any event, no later than five
(5) business days after the Effective Time, Watson shall deposit or cause to be
deposited with the Exchange Agent for exchange in accordance with this Article
I, the shares of Watson Common Stock issuable pursuant to Section 1.4 in
exchange for shares of Company Common Stock outstanding at the Effective Time
and a sufficient amount of cash to satisfy the cash payments to be made by
Watson to certain holders of Company Common Stock pursuant to Sections 1.4(e)
and 1.6(f) hereof.

         (c)   On or promptly after the Effective Time, Watson shall cause
the Exchange Agent to  mail to each holder of record of shares of Company
Common Stock (i) a letter of transmittal which shall specify that delivery
shall be effected, and risk of loss and title to such shares of Company Common
Stock shall pass, only upon delivery of the Certificates representing such
shares to Watson; and (ii) instructions for use in effecting the surrender of
such Certificates in exchange for the consideration to be received by such
holder pursuant to Sections 1.4 and 1.6 hereof.  Upon surrender of a
Certificate representing shares of Company Common Stock for cancellation to
Watson, together with such letter of transmittal, duly executed and completed
in accordance with the instructions thereto, the holder of the shares
represented by such Certificate





                                       8

<PAGE>   5
shall be entitled to receive in exchange therefor either (i) cash in accordance
with Section 1.4(e) hereof; or (ii)(A) a certificate representing that number
of whole shares of Watson Common Stock; and (B) a check representing the amount
of cash in lieu of fractional shares, if any, and unpaid dividends and
distributions, 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, in
each case, after giving effect to any required withholding tax, and the shares
represented by the Certificate so surrendered shall forthwith be canceled.  No
interest will be paid or accrued on the cash payable pursuant to Section 1.4(e)
hereof, the cash in lieu of fractional shares and unpaid dividends and
distributions, if any, payable to holders of shares of Company Common Stock who
receive shares of Watson Common Stock pursuant to Section 1.4 hereof.  In the
event of a transfer of ownership of Company Common Stock which is not
registered in the transfer records of the Company, the consideration to be paid
to such holder of Company Common Stock pursuant to Sections 1.4 and 1.6 hereof
may be issued to such a transferee if the Certificate representing such Company
Common Stock is presented to Watson, accompanied by all documents required to
evidence and effect such transfer and to evidence that any applicable stock
transfer taxes have been paid or, alternatively, payments of such transfer tax
to the Exchange Agent.  Until so surrendered, each Certificate that, at the
Effective Time, represented shares of Company Common Stock will be deemed from
and after the Effective Time, for all corporate purposes other than the payment
of dividends (except to the extent provided in Section 1.6(d) below), to
evidence the consideration to be received by the holders of Company Common
Stock pursuant to Sections 1.4 and 1.6 hereof.

         (d)     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 Company Common Stock
entitled to be converted into shares of Watson 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.

         (e)     At or after the Effective Time, there shall be no transfers on
the stock transfer books of the Company of the shares of Company Common Stock
which were outstanding at the Effective Time.  If, after the Effective Time,
Certificates are presented to the Surviving Corporation, they shall be canceled
and exchanged for the consideration set forth in this Article I deliverable in
respect thereof pursuant to this Agreement in accordance with the procedures
set forth in this Section 1.6.  Certificates surrendered for exchange by any
person constituting an





                                       9

<PAGE>   6
"affiliate" of the Company 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 an Affiliate Letter (as defined herein) from such person as
provided in Section 5.9.

         (f)     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, cash adjustments will be paid to holders
in respect of any fractional share of Watson Common Stock that would otherwise
be issuable, and the amount of such cash adjustment shall be equal to such
fractional proportion of the Average Closing Price of a share of Watson Common
Stock.

         (g)     All former stockholders of the Company (each, a "Stockholder"
and collectively the "Stockholders") shall look only to Watson for payment of
cash (if a Stockholder is to receive cash pursuant to Section 1.4(e) hereof),
shares of Watson Common Stock, cash in lieu of fractional shares and unpaid
dividends and distributions on the Watson Common Stock, as the case may be,
deliverable in respect of each share of Company Common Stock such stockholder
holds as determined pursuant to this Agreement, in each case, without any
interest thereon.

         (h)     None of Watson, Watson Sub, the Company, the Surviving
Corporation or any other person shall be liable to any former holder of shares
of Company Common Stock for any amount properly delivered to a public official
pursuant to applicable abandoned property, escheat or similar laws.

         (i)     In the event any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed and, if required by the
Surviving Corporation, the posting by such person of a bond in such reasonable
amount as the Surviving Corporation may direct as indemnity against any claim
that may be made against it with respect to such Certificate, Watson will issue
in exchange for such lost, stolen or destroyed Certificate, the consideration
to be received by the holder of such Certificate pursuant to Sections 1.4 and
1.6 hereof.

         (j)     Any portion of the property delivered to the Exchange Agent in
accordance with this Section 1.6 that remains unclaimed by the Stockholders one
year after the Effective Time shall be delivered to Watson.  Any Stockholders
who have not theretofore complied with this Section 1.6 shall thereafter look
only to Watson for payment of their consideration to be received by such
Stockholder pursuant to Sections 1.4 and 1.6 hereof deliverable in respect of
each share of the Company Common Stock such Stockholder holds as determined
pursuant to this Agreement, in each case, without any interest thereon.

         1.7.    Adjustment of Exchange Ratio.  In the event that, subsequent to
the date of this Agreement but prior to the Effective Time, the outstanding
shares of Watson Common Stock or  Company Common Stock shall have been changed
into a different number of shares or a different class as a result of a stock
split, reverse stock split, stock dividend, subdivision,





                                       10

<PAGE>   7
reclassification, split, combination, exchange, recapitalization or other
similar transaction, the Exchange Ratio and the Average Closing Price shall be
appropriately adjusted.

         1.8.  Tax Consequences and Accounting Treatment.  It is intended by
the parties hereto that the Merger shall constitute a reorganization within the
meaning of Section 368 of the Code and that the transaction be accounted for as
a pooling of interests.

         1.9.  Taking of Necessary Action; Further Action.  If, at any time
after the Effective Time, any further action is necessary or desirable to carry
out the purposes of this Agreement and to vest the Surviving Corporation with

                                  ARTICLE III

            REPRESENTATIONS AND WARRANTIES OF WATSON AND WATSON SUB

         Watson and Watson Sub represent and warrant to the Company that the
statements contained in this Article III are true and correct, except as set
forth in the disclosure statement delivered by Watson and Watson Sub to the
Company concurrently herewith and identified as the "Watson Disclosure
Statement."  All exceptions noted in the Watson Disclosure Statement shall be
numbered to correspond to the applicable sections to which such exception
refers; provided, however that any disclosure set forth on any particular
schedule shall be deemed disclosed in reference to all applicable schedules.

         3.1  Existence, Good Standing, Corporate Authority.  Each of Watson and
Watson Sub (i) is a corporation duly incorporated, validly existing and in good
standing under the laws of its respective jurisdiction of incorporation; (ii)
has all requisite power and authority to own or lease, and operate its
properties and assets, and to carry on its business as now conducted and as
currently proposed to be conducted, except where the failure to have such power
and authority would not have a Watson Material Adverse Effect (as defined
herein) and to consummate the transactions contemplated hereby; (iii) is duly
qualified or licensed to do business and is in good standing in all
jurisdictions in which it owns or leases property or in which the conduct of
its business requires it to so qualify or be licensed, except where the failure
to so qualify, individually or in the aggregate, would not have a Watson
Material Adverse Effect; and (iv) has obtained all licenses, permits,
franchises and other governmental authorizations necessary to the ownership or
operation of its properties or the conduct of its business, except where the
failure to have obtained such licenses, permits, franchises or authorizations
would not have a Watson Material Adverse Effect.  The copies of Watson's and
Watson Sub's Articles or Certificate of Incorporation and By-Laws as in effect

made available for the Company's review and are true and correct.  For purposes
of this Agreement, a "Material Adverse Effect" when used with respect to any
entity means (a) a material adverse effect on the business, results of
operations, financial condition or prospects of such entity and its
subsidiaries, taken as a whole, or (b) a material impairment in the ability of
such entity or its subsidiaries to perform any of their obligations under this

delivery of this Agreement and the other documents executed or to be executed
in connection herewith to which Watson or Watson Sub is a party (collectively,
the "Watson Ancillary Documents"), have been duly authorized by the Board of
Directors of Watson and Watson Sub and no other proceedings on the part of
Watson or Watson Sub or their stockholders are necessary to authorize the
execution, delivery or performance of this Agreement or any Watson Ancillary
Document.  This Agreement is, and, as of the Closing Date, each of the Watson
Ancillary Documents will be, a valid and binding obligation of Watson and/or
Watson Sub, as the case may be, enforceable against Watson and/or Watson Sub,





                                       12

<PAGE>   9
as the case may be, in accordance with its terms, except to the extent that
enforcement thereof may be limited by bankruptcy, insolvency; reorganization,
moratorium, fraudulent conveyance or other similar laws affecting enforcement
of creditors' rights generally, and by general principles of equity (regardless
of whether enforcement is considered in a proceeding at law or in equity).

         3.3  No Violation.  Neither the execution and delivery by Watson and
Watson Sub of this Agreement or the Watson Ancillary Agreements, nor the
consummation by Watson and Watson Sub of the transactions contemplated hereby
and thereby in accordance with their respective terms, will (a) conflict with
or result in a breach of any provisions of the Articles or Certificate of
Incorporation or By-Laws of Watson or Watson Sub; (b) result in a breach or

result in the creation of any lien, security interest, charge or encumbrance
upon any of the material properties of Watson or Watson Sub under, or result in
being declared void, voidable, or without further binding effect, any of the
terms, conditions or provisions of any note, bond, mortgage, indenture, deed of
trust or any material license, franchise, permit, lease, contract, agreement or
other instrument, commitment or obligation to which Watson or Watson Sub is a
party, or by which Watson or Watson Sub or any of their respective properties
is bound or affected, except for any of the foregoing matters which would not
have a Watson Material Adverse Effect; (d) contravene or conflict with or
constitute a violation of any provision of any law, regulation, judgement,
injunction, order or decree binding upon or applicable to Watson or Watson Sub,
except for any of the foregoing matters which would not have a Watson Material
Adverse Effect; or (e) other than the filings provided for in Sections 1.3 and
5.7, filings required under the Hart-Scott-Rodino Antitrust Improvements Act
of 1976 (the "HSR Act"), the Exchange Act, the Securities Act, or applicable
state securities and "Blue Sky" laws or filings in connection with the
maintenance of qualification to do business in other jurisdictions
(collectively, the "Regulatory Filings"), require any material consent,
approval or authorization of, or declaration of, or filing or registration
with, any domestic governmental or regulatory authority, the failure to obtain
or make which would have a Watson Material Adverse Effect.

         3.4  SEC Documents.  Watson has delivered or made available to the
Company each registration statement, report, proxy statement or information
statement (as defined in Regulation 14C under the Exchange Act) prepared by it
since January 1, 1994, which reports constitute all of the documents required
to be filed by Watson with the Securities and Exchange Commission ("SEC") since
such date, each in the form (including exhibits and any amendments thereto)
filed with the SEC (collectively, the "Watson Reports").  As of their
respective dates, the Watson Reports and any Watson Reports filed after the
date hereof and prior to the Effective Time (a) complied as to form in all
material respects with the applicable requirements of the Securities Act or the
Exchange Act, as the case may be, and the rules and regulations thereunder; and
(b) did not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein





                                       13

<PAGE>   10
or necessary to make the statements made therein, in the light of the
circumstances under which they were made, not misleading.  Watson has timely
filed with the SEC all reports required to be filed under Sections 13, 14 and
15(d) of the Exchange Act since January 1, 1994.  Each of the consolidated
balance sheets of Watson included in or incorporated by reference into the
Watson Reports (including the related notes and schedules) fairly present in
all material respects the consolidated financial position of Watson and the
Watson Subsidiaries as of its date (subject, in the case of unaudited
statements, to normal year-end audit adjustments which would not be material in
amount or effect), and each of the consolidated statements of income, retained
earnings and cash flows of Watson included in or incorporated by reference into
the Watson Reports (including any related notes and schedules) fairly present
in all material respects the results of operations, retained earnings or cash
flows, as the case may be, of Watson and the Watson Subsidiaries for the
periods set forth therein (subject, in the case of unaudited statements, to
normal year-end audit adjustments which would not be material in amount or
effect).  The financial statements of Watson, including the notes thereto,
included in or incorporated by reference into the Watson Reports comply as to
form in all material respects with applicable accounting requirements and with
the published rules and regulations of the SEC with respect thereto, and have
been prepared in accordance with generally accepted accounting principles
consistently applied ("GAAP") (except as may be indicated in the notes
thereto).  Since January 1, 1994, there has been no material change in Watson's
accounting methods or principles except as described in the notes to such
Watson financial statements.  All transactions entered into by Watson or its
Subsidiaries with Related Parties (as defined herein) that are required to be
disclosed in the Watson Reports have been properly disclosed, in all material
respects.

         3.5  No Brokers.  Watson has not entered into any contract, arrangement
or understanding with any person or firm which may result in the obligation of
the Company or Watson, Watson Sub or their respective Subsidiaries 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 Watson has retained Bear
Stearns & Co. Inc. as its financial advisor, the arrangements with which have
been disclosed in writing to the Company prior to the date hereof.

         3.6  Opinion of Financial Advisor.  Watson has received the opinion of
Bear Stearns & Co.  Inc., to the effect that, as of the date of such opinion,
the consideration to be paid by Watson pursuant to the Merger is fair to Watson
from a financial point of view.

         3.7  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 free
of preemptive rights.

         3.8  Capitalization





                                       14

<PAGE>   11
                (a)   The total authorized capital stock of Watson consists
of (i) 500,000,000 shares of Watson Common Stock, 36,818,957 shares of which
are issued and outstanding as of December 1, 1996 and (ii) 2,500,000 shares of
Preferred Stock, none of which are issued and outstanding as of the date of
this Agreement.  The authorized capital stock of Watson Sub consists of 1,000
shares of Common Stock, $0.01 par value per share, 100 shares of which, as of
the date hereof, are issued and outstanding and are held by Watson.  There are
no shares of capital stock of Watson or Watson Sub of any other class
authorized, issued or outstanding.  Except as set forth in the Watson
Disclosure Statement, Watson has not issued any shares of Watson Common Stock
or Preferred Stock since December 1, 1996.  All of such outstanding shares of
Watson Common Stock have been validly issued, are fully paid and nonassessable
and were issued in compliance with all preemptive rights.

                (b)   Except as set forth in the Watson Disclosure Statement, 
there are currently no outstanding, and as of the Closing; there will be no 
outstanding (i) securities convertible into or exchangeable for any capital 
stock of Watson or any of the Watson Significant Subsidiaries (as defined 
below), (ii) options, warrants or other rights to purchase or subscribe to 
capital stock of Watson or any of the Watson Significant Subsidiaries or
securities convertible into or exchangeable for capital stock of Watson or any
of the Watson Significant Subsidiaries, or (iii) contracts, commitments,
agreements, understandings, arrangements, calls or claims of any kind relating
to the issuance of any capital stock of Watson or any of the Watson Significant
Subsidiaries. For purposes of this Agreement, a "Watson Significant Subsidiary"
shall mean each Subsidiary of Watson which has total assets or total revenues
for the previous fiscal year in excess of $10,000,000.

           3.9  Material Adverse Change.  Since September 30, 1996 to the date
of this Agreement, Watson, Watson Sub and their Subsidiaries, taken as a whole,
have not suffered any change in their businesses, operations, assets,
liabilities, financial condition or prospects which would reasonably have a
Watson Material Adverse Effect; provided, that a Watson Material Adverse Effect
will not be deemed to have occurred solely as a result of fluctuations in the
value of Watson Common Stock due to or arising from any public disclosures by
Watson (including its 50% Subsidiary, Somerset Pharmaceuticals, Inc.),
including, without limitation, disclosures relating to Watson's entering into
any other transactions (including, without limitation, transactions relating to
the acquisition of assets, stock or merger transactions).  Since September 30,
1996 to the date of this Agreement, (a) Watson, Watson Sub and their
Subsidiaries have not entered into any transaction outside the ordinary course
of business which will be required to be disclosed in Watson's Form 10-K for
the year ended December 31, 1996; (b) Watson has not (i) declared, set aside or
paid any dividend or made any other distribution or payment with respect to any
shares of its capital stock or other ownership interests; or (ii) directly or
indirectly, redeemed, purchased or otherwise acquired any shares of its capital
stock, or made any commitment for any such action; or (c) neither Watson nor
any Watson Significant Subsidiary has voluntarily elected to alter the manner
of keeping its books, accounts or records, or changed in any manner the
accounting practices therein reflected, except for (i) changes that would not
have a Watson Material Adverse Effect; or (ii) changes in accounting laws which
effect all pharmaceutical companies generally.





                                       15

<PAGE>   12
         3.10    Litigation.  There is no litigation or proceeding, in law or
in equity, and there are no proceedings or governmental investigations before
any commission or other administrative authority, pending or, to Watson's
knowledge, threatened against Watson, any of the Watson Significant
Subsidiaries or any of Watson's or the Watson Significant Subsidiaries'
respective officers, directors or affiliates, with respect to or affecting
Watson's or any of the Watson Significant Subsidiaries' operations, business,
products, sales practices or financial condition, or related to the
consummation of the transactions contemplated hereby, or by the Watson
Ancillary Documents or the Ancillary Documents which, in each case, if
conducted with results unfavorable to Watson or any of the Watson Significant
Subsidiaries, would have a Watson Material Adverse Effect.  There are no facts
known to Watson which, if known by a potential claimant or governmental
authority, would reasonably give rise to a claim or proceeding which, if
asserted or conducted with results unfavorable to Watson or any of the Watson
Significant Subsidiaries, would have a Watson Material Adverse Effect.

         3.11    Disclosure Documents.  The Proxy Statement/Prospectus to be
delivered to the Stockholders in connection with the approval of the
transactions contemplated by this Agreement, or any amendment or supplement
thereto (the "Proxy Statement") at the time of mailing thereof and at the time
of the meeting of Stockholders, or, in the case of the Form S-4 (as defined in
Section 5.7 of this Agreement) and each amendment or supplement thereto, at the
time it is filed or becomes effective under the Securities Act, will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading;
provided, however, that the foregoing shall not apply to the extent that any
such untrue statement of a material fact or omission to state a material fact
was made by Watson in reliance upon and in conformity with written information
concerning the Company furnished to Watson by the Company specifically for use
in the Proxy Statement.

         3.12    Tax Reorganization; Accounting Matters.  Neither Watson nor
any of its Subsidiaries has taken or failed to take any action which would
prevent the Merger from (a) constituting a reorganization within the meaning of
section 368(a) of the Code; or (b) being treated as a "pooling or interests" in
accordance with Accounting Principles Board Opinion No. 16, the interpretative
releases issued pursuant thereto, and the pronouncements of the SEC.

         3.13    Compliance with Laws--General.  Watson and each of the Watson
Significant Subsidiaries are in substantial compliance with all foreign,
federal, state or local laws, ordinances or regulations of any court, arbitral,
tribunal, administrative agency or commissioner or other governmental or other
regulatory authority or agency ("Governmental Entities") (including, but not
limited to, those related to occupational health and safety, controlled
substances, Environmental Laws (as defined herein), Tax (as defined herein)
laws, labor, ERISA (as defined herein), the Foreign Corrupt Practices Act,
employment and employment practices or EEOC matters) that are applicable to
Watson and each Watson Significant Subsidiary or affect or relate to this
Agreement or the transactions contemplated hereby, except for any such
noncompliance that would not, individually or in the aggregate, have a Watson
Material Adverse Effect. To Watson's knowledge, there has been





                                       16

<PAGE>   13
no storage, treatment, generation, transportation or Release (as defined
herein) of any Materials of Environmental Concern (as defined herein) by
Watson, any Watson Significant Subsidiary or by any other person or entity for
which Watson or any Watson Significant Subsidiary is or may be held
responsible, at any Facility (as herein defined) or any Offsite Facility (as
herein defined) in violation of, or which could give rise to any material
obligation under, Environmental Laws, where such liability or obligation would
be reasonably likely to have a Watson Material Averse Effect.

         3.14    Compliance with Laws--FDA.

         (a)     Watson and each Watson Significant Subsidiary are in
substantial compliance with all Federal and state laws applicable to the
manufacture, processing, packing, testing and sale of pharmaceutical products
to the extent such laws are applicable to them, all rules and regulations of
the Food and Drug Administration ("FDA") and the U.S. Drug Enforcement Agency
(the "DEA"),  to the extent such rules and regulations are applicable to them,
each new drug application ("NDA") and abbreviated new drug application ("ANDA")
and each of its establishment license applications ("ELA") and/or product
license applications ("PLA") in which Watson or any of the Watson Significant
Subsidiaries have sold any product on or after July 17, 1995, except where the
failure to be in such compliance would not have a Watson Material Adverse
Effect.

         (b)     At any time after July 17, 1995, neither Watson, the Watson
Significant Subsidiaries nor, to the knowledge of Watson, their respective
officers, employees, or agents have made an untrue statement of material fact
or fraudulent statement to the FDA or the DEA, failed to disclose a material
fact required to be disclosed to the FDA or the DEA, or committed an act, made
a statement, or failed to make a statement that could reasonably be expected to
provide a basis for the FDA to invoke its policy respecting "Fraud, Untrue
Statements of Material Facts, Bribery, and Illegal Gratuities," set forth in 56
Fed. Reg 46191 (September 10, 1991).

         (c)     At any time after July 17, 1995, neither Watson nor any of the
Watson Significant Subsidiaries have received any written notice that the FDA
or the DEA has commenced, or threatened to initiate, any judicial action
against or to withdraw its approval or request the recall of any product of
Watson or any of the Watson Significant Subsidiaries, where such product
withdrawal or recall would have a Watson Material Adverse Effect, or commenced
or threatened to initiate, any action to enjoin production at any facility
owned or used by Watson or any of the Watson Significant Subsidiaries or any
other facility at which any of Watson's or any of the Watson Significant
Subsidiaries' products are manufactured, processed, packaged, labeled, stored,
distributed, tested or otherwise handled (the "Manufacturing Locations"), where
such action would have a Watson Material Adverse Effect.

         (d)     Watson has made available to the Company copies of any and all
material reports of inspection observations, establishment inspection reports,
warning letters and any other material documents received from or issued by the
FDA or the DEA since January 1, 1995 that indicate or suggest a lack of
material compliance with the FDA or the DEA regulatory requirements by Watson
or by any Watson Significant Subsidiary.

and ordinary manner, in accordance with GAAP and with respect to Watson and the
Watson Significant Subsidiaries other than Circa Pharmaceuticals, Inc.

1995, all material transactions to which Watson or any Watson Significant
Subsidiary is or has been a party, taken as a whole, are properly reflected
therein.

with the lapse of time, the giving of notice, or both, or the happening of any
further event or condition, would become a default of a material provision
under any such agreement, lease, sublease or other instrument by the Company or
its Subsidiaries, or, to the knowledge of the Company, the other contracting
party.  Neither the Company nor any of its Subsidiaries has released or waived
any material right under any such agreement, lease, sublease or other
instrument other than in the ordinary course of business consistent with past
practices.

         (c) Immediately after the Closing, except as contemplated by this
Agreement, neither the Company nor any of its Subsidiaries will be bound by the
terms of any stock option agreement, registration rights agreement,
stockholders agreement, management agreement, consulting agreement or any other
agreement relating to the equity or management of the Company or its
Subsidiaries.

         (d) Neither the Company nor any of its Subsidiaries is a party to, or
bound by, any unexpired, undischarged or unsatisfied written or oral contract,
agreement, indenture, mortgage, debenture, note or other instrument under the
terms of which performance by the Company or its Subsidiaries according to the
terms of this Agreement will be a default of a material provision under or an
event of acceleration, or grounds for termination, or whereby timely
performance by the Company of this Agreement may be prohibited, prevented or
delayed.

         4.19.  Insurance.  The Disclosure Statement contains a true and
correct list of all insurance policies which are owned by the Company or its
Subsidiaries or which name the Company or any of its Subsidiaries as an insured
(or loss payee), including without limitation those which pertain to the
Company's or its Subsidiaries' assets, employees or operations.  All such
insurance policies are in full force and effect and neither the Company nor any
of its Subsidiaries have received notice of cancellation of any such insurance
policies.  In the two (2) year period ending on the date hereof, neither the
Company nor any of its Subsidiaries have received any written notice from, or
on behalf of, any insurance carrier relating to or involving an annual increase
by over 10% in insurance rates (except to the extent that insurance risks may
be increased for all similarly situated risks) or non-renewal of a policy, or
requiring or suggesting material alteration of any of the Company's or its
Subsidiaries' assets, purchase of additional equipment, or material
modification of any of the Company's or its Subsidiaries' methods of doing
business.  Neither the Company nor any of its Subsidiaries made any claim for
reimbursement from its insurance carriers since June 30, 1993.

         4.20.  Litigation.  Except as set forth in the Disclosure Schedule or
matters which are immaterial to the Company or its Subsidiaries, there is no
litigation or proceeding, in law or in





                                       29

<PAGE>   26
equity, and there are no proceedings or governmental investigations before any
commission or other administrative authority, pending or, to the Company's
knowledge, threatened against the Company or any of its Subsidiaries, or any of
the Company's or its Subsidiaries' respective officers, directors or
affiliates, with respect to or affecting the Company's or its Subsidiaries'
respective operations, businesses, products, sales practices or financial
condition, or related to the consummation of the transactions contemplated
hereby or by the Watson Ancillary Documents or the Ancillary Documents.  There
are no facts known to the Company which, if known by a potential claimant or
governmental authority, would reasonably give rise to a claim or proceeding
which, if asserted or conducted with results unfavorable to the Company or its
Subsidiaries, would have a Company Material Adverse Effect.

         4.21.  Warranties. To the Company's knowledge, neither the Company nor
any of its Subsidiaries has made any oral or written warranties with respect to
the quality or absence of defects of its products or services which they have
sold or performed which are in force as of the date hereof except as are
described in the Disclosure Statement.  There are no material claims pending
or, to the knowledge of the Company, threatened against the Company or any of
its Subsidiaries with respect to the quality of or absence of defects in such
products or services nor are there any facts known to the Company relating to
the quality of or absence of defects in such products or services which, if
known by a potential claimant or governmental authority, would reasonably give
rise to a material claim or proceeding.  The Disclosure Statement sets forth a
summary, which is accurate in all material respects, of all returns of products
during the period beginning January 1, 1995 and ending on the date hereof, and
all credits and allowances for returned products given to customers during said
period to the extent that such returns, credits and allowances with respect to
any one product exceeds $50,000 in the aggregate, and said summary contains a
description of any reoccurring product defects (other than returns due to date
expirations).  The Company has no knowledge of or reason to believe that the
percentage of warranty claims or product returns for products sold by the
Company and its Subsidiaries prior to the Closing Date will exceed historical
levels.

         4.22. Products Liability. Neither the Company nor any of its
Subsidiaries have received any written notice relating to, nor does the Company
have knowledge of any facts or circumstances which could reasonably give rise
to, any claim involving any product manufactured, produced, distributed or sold
by or on behalf of the Company or its Subsidiaries resulting from an alleged
defect in design, manufacture, materials or workmanship, or any alleged failure
to warn, or from any breach of implied warranties or representations, other
than notices or claims that have been settled or resolved by the Company or its
Subsidiaries prior to the date of this Agreement.

         4.23.  Arbitration.  Neither the Company nor any of its Subsidiaries
is a party to, or bound by, any decree, order or arbitration award (or
agreement entered into in any administrative, judicial or arbitration
proceeding with any governmental authority) with respect to or affecting the
properties, assets, personnel or business activities of the Company or its
Subsidiaries.

         4.24.  Taxes.
                ------

         (a) As used in this Agreement, (i) the term "Taxes" means all federal,
state, local, foreign and other net income, gross income, gross receipts, sales,
use, ad valorem, transfer, franchise, profits, license, lease, service, service
use, withholding, payroll, employment, excise, severance, stamp, occupation,
premium, property, windfall profits, customs, duties or other taxes, fees,
assessments or charges of any kind whatever of a nature similar to taxes,
together with any interest and any penalties, additions to tax or additional
amounts with respect thereto, and the term "Tax" means any one of the foregoing
Taxes; and (ii) the term "Returns" means all returns, declarations, reports,
statements and other documents required to be filed in respect of Taxes, and the
term "Return" means any one of the foregoing Returns.

         (b) There have been properly completed and filed on a timely basis and
in correct form all material Returns required to be filed by the Company or any
of its Subsidiaries.  As of the time of filing, the foregoing Returns were
correct and complete in all material respects.  An extension of time within
which to file any Return which has not been filed has not been requested or
granted.

         (c) With respect to all amounts in respect of Taxes imposed upon the
Company or any of its Subsidiaries, or for which the Company or any of its
Subsidiaries is or could be liable, whether to taxing authorities (as, for
example, under law) or to other persons or entities (as, for example, under tax
allocation agreements), with respect to all taxable periods or portions of
periods ending on or before September 30, 1996, (i) all applicable tax laws and
agreements have been complied with in all material respects, and (ii) all
amounts required to be paid by the Company or its Subsidiaries, to taxing
authorities or others, on or before the date hereof have been paid or
adequately reserved for on the financial statements contained in the Company
Reports, and any Taxes accrued but not due and payable as of September 30, 1996
have been accrued or otherwise reserved for in financial statements contained
in the most recent Company Report.  No Taxes have been (or will prior to the
Closing Date be) recorded by the Company or any of its Subsidiaries other than
in the ordinary course of business.  There are no Liens filed against any asset
of the Company or any of its Subsidiaries resulting from the failure to pay any
Tax when due.

         (d) To the Company's knowledge, no issues have been raised (and are
currently pending) by any taxing authority in connection with any of the
Returns.  No waivers of statutes of limitation with respect to the Returns have
been given by the Company or any of its Subsidiaries (or with respect to any
Return which a taxing authority has asserted should have been filed by the
Company or any of its Subsidiaries) which waivers are still in effect.  The
Disclosure Statement sets forth those years for which examinations have been
completed, those years for which examinations are presently being conducted,
and those years for which Returns will be required but are not yet due to be
filed and have not yet been filed.  All deficiencies asserted or assessments
made as a result of any examinations have been fully paid, or are fully
reflected as a liability in the financial statements contained in the Company
Report, or are being contested and an adequate reserve therefor has been
established and is fully reflected as a liability in the financial statements
contained in the most recent Company Report.





                                       31
<PAGE>   28
         (e) The unpaid Taxes of the Company or any of its Subsidiaries do not
materially exceed the reserve for tax liability (excluding any reserve for
deferred Taxes established to reflect timing differences between book and tax
income) set forth or included in the financial statements included in the most
recent Company Report, as adjusted for the passage of time through the Closing.

         (f) Neither the Company nor any of its Subsidiaries is or at any time
has been a party to or bound by (nor will the Company or any of its
Subsidiaries become a party to or bound by) any tax indemnity, tax sharing or
tax allocation agreement.

         (g) Neither the Company nor any of its Subsidiaries has ever been a
member of an affiliated group of corporations, within the meaning of section
1504 of the Code.

         (h) All material elections with respect to Taxes affecting the Company
or any of its Subsidiaries that are currently effective as of the date hereof
that are not reflected in the Company's Returns are set forth in the Disclosure
Statement.

         4.25.  ERISA.  The Disclosure Schedule contains a list and brief
description of all "employee pension benefit plans" (as defined in Section 3(2)
of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"))
(sometimes referred to herein as "Pension Plans"), "employee welfare benefit
plans" (as defined in Section 3(1) of ERISA and referred to herein as a
"Welfare Plan") and all other Benefit Plans (defined herein as any Pension
Plan, Welfare Plan and any other plan, fund, program, arrangement or agreement
to provide employees, directors, independent contractors, officers or agents of
any Commonly Controlled Entity with medical, health, life, bonus, stock
(option, ownership or purchase), deferred compensation, severance, salary
continuation, vacation, sick leave, fringe, incentive insurance or other
benefits) maintained, or contributed to, or required to be contributed to, by
the Company or any of its subsidiaries or any other Person that, together with
the Company at any time during the last six years, is or was treated as a
single employer under Section 414(b), (c), (m) or (o) of the Code (the Company
and each such other Person, a "Commonly Controlled Entity") for the benefit of
any current or former employees, officers or directors of any Commonly
Controlled Entity. The Company has delivered or made available to Watson true,
complete and correct copies of (i) each Benefit Plan (or, in the case of any

with respect to each Benefit Plan (if any such report was required), (iii) the

summary plan description is required, (iv) each trust agreement and group
annuity contract relating to any Benefit Plan; and (v) a list of all assets and
liabilities of, allocated to or accounted for separately with respect to every
Benefit Plan (including insurance contracts associated with every Benefit Plan
regardless of whether any current cash value exists).  Each Benefit Plan has
been established, funded, maintained and administered in all material respects
in accordance with its terms and is in compliance with the applicable
provisions of ERISA, the Code, all other applicable laws and all applicable
collective bargaining agreements except where the failure to comply would not
be reasonably expected to result in a Company Material Adverse Effect.

                 (b)      All Pension Plans have been the subject of favorable
and up-to-date (through any applicable remedial amendment period) determination
letters from the Internal Revenue Service, or have filed a timely application
therefor, to the effect that such Pension Plans are qualified and exempt from
federal income taxes under Section 401(a) and 501(a), respectively, of the
Code, and no such determination letter has been revoked nor has any such

letter or application therefor in any respect that would adversely affect its
qualification or materially increase its costs.

                 (c)      No Commonly Controlled Entity has adopted or been
obligated to contribute to any "defined benefit pension plan" as defined in
Section 3(35) of ERISA subject to Title IV of ERISA in the five years preceding

any time within the five calendar years preceding the date hereof or is
required currently to contribute to any "multiemployer plan" (as defined in
Section 4001(a)(3) of ERISA ) or has withdrawn from any multiemployer plan
where such withdrawal has either: (i) resulted or would result in any
"withdrawal liability" (within the meaning of Section 4201 of ERISA) that has
not been fully paid; or (ii) engaged in a transaction that might have resulted
in withdrawal liability but for the application of Section 4204 of ERISA.

                 (e)      With respect to any Welfare Plan, (i) no such Welfare
Plan is funded through a "welfare benefits fund", as such term is defined in
Section 419(e) of the Code, (ii) no such Welfare Plan is self-insured, and
(iii) each such Welfare Plan that is a "group health plan", as such term is
defined in Section 5000(b)(1) of the Code, complies with the applicable
requirements of Section 4980B(f) of the Code.

                 (f)      Except as set forth in the Disclosure Schedule,
neither the Company or any Commonly Controlled Entity nor any Person acting on
behalf of the Company or any Commonly Controlled Entity has, in contemplation
of any corporate transaction involving Watson, issued any written communication
to, or otherwise made or entered into any legally binding commitment with, any
employees of the Company or of any Commonly Controlled Entity to the effect
that, following the date hereof, (i) any benefits or compensation provided to
such employees under existing Benefit Plans or under any other plan or
arrangement will be enhanced, (ii) any new plans or arrangements providing
benefits or compensation will be adopted, (iii) any Benefit Plans will be
continued for any period of time or cannot be amended or terminated at any time
or for any reason, or (iv) any plans or arrangements provided by Watson will be

                 (g)      No Commonly Controlled Entity has ever promised or
been obligated to provide former employees with coverage or benefits under
Benefit Plans, other than as required by Section 4980B of the Code.

                 (h)      All contributions or premiums owed by Commonly
Controlled Entities with respect to Benefit Plans under law, contract or
otherwise have been made in full and on a timely basis and Commonly Controlled
Entities are not obligated to contribute with respect to any Benefit





                                       33
<PAGE>   30
Plan that involves a retroactive contribution, assessment or funding waiver
arrangement.  All administrative costs attributable to Benefit Plans have been
paid when due.

                 (i)      To the Company's knowledge, no Pension Plan or
Welfare Plan or any "fiduciary" or "party-in-interest" (as such terms are
respectively defined by Sections 3(21) and 3(14) of ERISA) thereto has engaged
in a transaction prohibited by Section 406 of ERISA or 4975 of the Code for
which a valid exception is not available.

                 (j)      There are no pending or, to the Company's knowledge,
threatened likely claims, lawsuits, arbitrations or audits asserted or
instituted against any Benefit Plan, any fiduciary (as defined by Section 3(21)
of ERISA thereto, any Commonly Controlled Entity or any employee or
administrator thereof in connection with the existence, operation or
administration of a Benefit Plan, other than routine claims for benefits.

                 (k)      Nothing in this Agreement or the transaction
contemplated hereunder will: (i) cause the termination or repricing of any
insurance contract to which a Commonly Controlled Entity or Benefit Plan is a
party to the purposes of providing employee benefits; (ii) trigger a right of
any employee of any Commonly Controlled Entity to severance, deferred
compensation or retirement benefits; or (iii) cause any early withdrawal or
premature termination penalty with respect to any asset held in connection with
any Benefit Plan.

                 (l)      No Commonly Controlled Entity maintains any unfunded
plan of deferred compensation.

         4.33.  Absence of Indemnifiable Claims, etc.  There are no pending
claims and, to the knowledge of the Company, no facts that would reasonably

employees are terminated, such employees who remain employees of the Surviving
Corporation shall be entitled to participate in all benefit plans and
arrangements that are available and subsequently become available to Watson's
employees on the same basis as Watson's employees in similar positions are
eligible to participate.  For purposes of satisfying the terms and conditions
of such plans, Watson shall give full credit for eligibility, vesting or
benefit accrual for each participant's period of service with the Company prior
to the Effective Time.   To the extent Watson's benefit plans provide medical
or dental welfare benefits after the Closing Date, Watson shall cause all
pre-existing condition exclusions and actively at work requirements to be
waived and Watson shall provide that any expenses incurred on or before the
Closing Date shall be taken into account under Watson's benefit plans for
purposes of satisfying the applicable deductible, coinsurance and maximum
out-of-pocket provisions for such employees and their covered dependents.

         5.13  Company Options.  Immediately after the Effective Time, but in
any event, no later than three business days after the Closing Date, Watson
shall register the shares of Watson Common Stock issuable upon exercise of such
Company Options with the SEC on Form S-8, to the extent that such Company
Options may be registered on such form.  To the extent that all or any portion
of the





                                       47
<PAGE>   44
Company Options may not be registered on Form S-8 (the "Non-Employee Options"),
Watson and the Company shall cooperate and promptly prepare and Watson shall
file with the SEC as soon as practicable a Registration Statement on Form S-3
(the "Form S-3") under the Securities Act, with respect to the Watson Common
Stock issuable upon exercise of the Non-Employee Options.  Watson shall use all
reasonable efforts, and the Company will cooperate with Watson, to have the
Form S-3 declared effective by the SEC on or prior to the Effective Date.
Watson will advise holders of such Non-Employee Options, promptly after it
receives notice thereof, of the time when the Form S-3 has become effective,
the issuance of any stop order or the suspension of the qualification of the
Watson Common Stock issuable in connection with the exercise of the
Non-Employee Options for offering or sale in any jurisdiction and Watson shall
use its best efforts to promptly resolve any such stop order, suspension or
qualification.

               --------------------------------------------------------

         (a)   From and after the Effective Time of the Merger, Watson agrees
to indemnify and hold harmless, and to cause the Surviving Corporation to honor
its separate indemnification to, each person who is an officer or director of
the Company or its Subsidiaries on the date of this Agreement (an "Indemnified
Person") from and against all damages, liabilities, judgments and claims (and
related expenses including, but not limited to, attorney's fees and amounts
paid in settlement) based upon or arising from his or her capacity as an
officer or director of the Company or its Subsidiaries, to the same extent he
or she would have been indemnified under the Articles of Incorporation or
By-laws of Watson as such documents were in effect on the date of this
Agreement and to the extent permitted under applicable law.  Subject to an
Indemnified Person's obligation to refund any advances in accordance with the
Florida Business Corporation Act, Watson shall advance all litigation costs
reasonably incurred by such Indemnified Person in accordance with applicable
law.

         (b)   The rights granted to the Indemnified Persons hereby shall be
contractual rights inuring to the benefit of all Indemnified Persons and shall
survive this Agreement and any merger consolidation or reorganization of
Watson.

         (c)   The rights to indemnification granted by this Section 5.14 are
subject to the following limitations: (i) amounts otherwise required to be paid
by Watson to an Indemnified Person pursuant to this Section 5.14 shall be
reduced by any amounts that such Indemnified Person has recovered by virtue of
the claim for which indemnification is sought and Watson shall be reimbursed
for any amounts paid by Watson that such Indemnified Person subsequently
recovers by virtue of such claim; (ii) any claim for indemnification pursuant
to this Section 5.14 must be submitted in writing to the Chief Executive
Officer or Chairman of Watson promptly upon such Indemnified Person becoming
aware of such claim, provided that any such failure to advise promptly will not
cause a loss of indemnity unless it has a prejudicial effect on Watson; and
(iii) an Indemnified Person shall not settle any claim for which
indemnification is provided herein without the prior written consent of Watson,
which consent shall not be unreasonably withheld.

reasonable best efforts to cause financial results covering at least thirty

quarterly financial statements as soon as practicable after such information is
required to be filed with the SEC.

         5.16  Agreement with respect to Products under Development.  As soon
as practicable after the date hereof, but in any event within ten (10) business
days after the date hereof, Watson and the Company shall negotiate in good
faith and shall use their best efforts to enter into an agreement with respect
to the development and sale of all of the Company's products under development.

of the Merger pursuant to this Article 7, all obligations of the parties hereto
shall terminate, except the obligations of the parties pursuant to this Section
7.5 and the provisions of Sections 5.6 and 5.10, which obligations shall

inaccuracies in the representations and warranties made to such party contained
herein or in any document delivered pursuant hereto; and (c) waive compliance
with any of the agreements or conditions for the benefit of such party

FOR IMMEDIATE RELEASE
- ---------------------

              WATSON PHARMACEUTICALS TO ACQUIRE ROYCE LABORATORIES
           ACQUISITION TO COMPLEMENT WATSON'S OFF-PATENT PRODUCT LINE

CORONA, CA -- (December 26, 1996) -- Watson Pharmaceuticals, Inc. (Nasdaq:
WATS) and Royce Laboratories, Inc. (Nasdaq: RLAB) ("Royce"), jointly announced
that their respective boards of directors unanimously approved, and both
companies have signed, a definitive agreement for Watson Pharmaceuticals to
acquire Royce in a stock-for-stock merger transaction to be accounted for as a
"pooling of interests."  Royce will become a wholly-owned subsidiary of Watson
through an exchange of Watson shares worth the equivalent of $7.25 for each
share of Royce, with the exception that small shareholders of Royce shares will
be cashed out for $7.25.  The acquisition is expected to be accretive to
Watson's 1997 per share earnings, and to be completed by late February, 1997.

         Royce Laboratories, headquartered in Miami, Florida, manufactures and
markets off-patent prescription drugs in solid dosage form.  Royce presently
manufactures and markets 19 off-patent prescription drugs in 40 dosage
strengths.  Additionally, Royce has abbreviated new drug applications pending
for 11 additional off-patent prescription drugs and is engaged in the
development of approximately 15 off-patent prescription drugs.

         Dr. Allen Chao, Chairman and Chief Executive Officer of Watson
commented, "Royce was particularly attractive to us from an acquisition
standpoint as their business complements our existing business.  This
acquisition fits perfectly with our current strategy of focusing on the
development, production and marketing of difficult-to-produce niche
pharmaceuticals."

         Patrick J. McEnany, Chairman and Chief Executive Officer of Royce
added, "We are very excited to join a leader in specialty and off- patent
pharmaceuticals, and view this transaction as a tremendous opportunity for
Royce.  With Watson's expertise and resources, we will dramatically enhance our
ability to realize the potential of our business plans in both the
manufacturing and marketing of off-patent pharmaceutical products."

         Under the terms of the definitive agreement signed by both companies,
Royce will become a wholly-owned subsidiary of Watson, and Patrick McEnany will
become President of the wholly-owned subsidiary, Royce Laboratories, Inc., as
well as Vice President of Corporate Development for Watson Pharmaceuticals,
Inc., reporting to Dr. Chao.

         The proposed transaction is subject to approval of Royce's
stockholders, the expiration of the waiting period under the Hart-Scott- Rodino
Antitrust Improvement Act and other customary conditions to closing.  The
exchange ratio will be based on the price of Watson shares for the 10 days
preceding the day prior to the closing, subject to a collar on Watson's stock
price of $38 to $47 per share.  Royce presently has approximately 13.5 million
shares outstanding and Watson has approximately 36.8 million shares
outstanding.

         The following important factors may affect Watson's and Royce's actual
results and could cause such results to differ materially from forward-looking
statements made by or on behalf of Watson and/or Royce.  Such factors include,
but are not limited to, changing market conditions, the availability and cost
of raw materials, the impact of competitive products and pricing, the timely
development, FDA approval and market acceptance of Watson's and Royce's
products, the timely implementation of certain cost saving measures and other
risks detailed herein and from time to time in Watson's and Royce's Securities
and Exchange Commission filings.

         Royce Laboratories, Inc., headquartered in Miami, FL, manufactures and
markets off-patent prescription drugs in solid dosage form.

         Watson Pharmaceuticals, Inc., headquartered in Corona, CA, is engaged
in the manufacture and sale of off-patent medications and the development of
proprietary pharmaceutical products.
