      5. PROTECTION OF CONFIDENTIAL INFORMATION: NON-COMPETITION.

previously established by the COMPANY the EMPLOYEE agrees:

                 5.1.1 That the following definitions shall apply:
                 a.  "Confidential Information" means any and all data and
information related to COMPANY projects, including, but not limited to
customer and contact lists, production contacts and pricing, marketing and
financial information, records, business plans, studies, reviews and projects.

               b.  "Directly or indirectly" shall include, without limitation,
acting as a sole proprietor, partner, joint venturer, beneficiary,
shareholder, director, officer, employee, independent contractor, consultant
or agent, by or through any friend, relative, trustee, intermediary, or other
agent, or in any other manner or capacity.

               c.  "Person" shall include, without limitation, an in the
singular as well as in the plural, natural persons, proprietorship,
partnerships, joint ventures, corporations, estates, trusts, fellowships,
clubs, societies, leagues, firms, groups, associations, agencies, enterprises,

                               -8-

<PAGE>

               d.  "Trade secret" means information, including a compilation,
program, device, method, technique or process that" (i) derives independent
economic value, actual or potential, from not being generally known to, and
not being readily ascertainable by proper means by other persons who can
obtain economic value from its disclosure or use, and (ii) is the subject of
efforts that are reasonable under the circumstances to maintain its secrecy.

            5.2 The parties acknowledge and recognize the highly competitive
nature of the COMPANY'S business and the competition between the COMPANY and
its competitors in the industry.  The parties further acknowledge that the
accounts for which EMPLOYEE will be responsible constitute confidential
information and proprietary information previously obtained by the COMPANY and
the sole property of the COMPANY and which the EMPLOYEE, but for his
employment with the COMPANY, would have no exposure or contact with.

            5.3 To deliver promptly to the COMPANY on termination of his
employment by the COMPANY, or at any time the COMPANY may so request, all
memoranda, notes, records, reports, manuals, drawings, blueprints and other
documents (and all copies thereof) relating to the COMPANY'S business and all
property associated therewith, which he may then possess or have under his
control.

            5.4 The parties agree that the compliance with the provisions of
this paragraph 5 are material considerations of this Agreement and that the
COMPANY would not have entered into this Agreement but for such provision.
The parties agree that any
                               -9-
<PAGE>

violation of this paragraph 5 will cause significant and irreparable harm to
the COMPANY for which it has no adequate remedy at law, regardless of the
outcome of any litigation between the parties or money damages awarded
therein.  The COMPANY, upon application to a court of competent jurisdiction
shall be entitled to obtain injunctive relief, including but not limited to a
temporary restraining order or temporary, preliminary, or permanent
injunction, without the necessity of a bond, to enforce the provisions of this
Agreement.  The COMPANY shall also be entitled to an accounting of and
constructive trust for all profits or other benefits arising out of or related
to any such violation.  The COMPANY does not waive its right to and shall be
entitled to any remedy available at law, including monetary remedies,
including the liquidated damages provided for herein for a violation of this
Agreement.  The EMPLOYEE agrees that the existence of any claims it has
against the COMPANY shall not constitute a defense to the enforcement of any
of the provisions of the Agreement.

            5.5 In addition to any other remedy set forth herein, the parties
acknowledge and agree that the EMPLOYEE shall pay to the COMPANY Twenty-Five
Thousand ($25,000) Dollars for each instance or event of a threatened or
material breach of any of the provisions of this paragraph 5.  This amount
shall be liquidated damages and not a penalty.  The parties recognize that
actual damages resulting to the COMPANY from such breach would be difficult or
impossible to measure due to the nature of the COMPANY'S business and that
this amount is a reasonable estimate of what such damages would be.

                               -10-

<PAGE>

            5.6 To deliver promptly to the COMPANY on termination of his
employment by the COMPANY, or at any time the COMPANY may so request, all
client lists, memoranda, notes, records, reports, manuals, drawings,
blueprints and other documents (and all copies thereof) relating to the
COMPANY'S business and all property associates therewith, which he may then
possess or have under his control

            5.7 Restrictive Covenants.  During the Term and for a period of
two (2) years following the termination of such period, the EMPLOYEE shall
not, directly or indirectly, enter the employ of, or render any services to,
any person, firm or corporation which is in the competition with the COMPANY
in any way in the capacity of CFO or related position; and he shall not become
interested in any such practice, directly or indirectly, as an individual,
partner, shareholder, director, officer, principal, agent, employee, trustee,
consultant, or any other relationship or capacity; provided, however, that
nothing contained in this Section 5.7 shall be deemed to prohibit the EMPLOYEE
from acquiring, solely as an investment, shares of capital stock of any public
corporation.  In the event a court of competent jurisdiction shall
subsequently ascertain that the geographic scope or duration of the within
Restrictive Covenant is unenforceable in any respect, then the parties agree
and consent to the reformation of this clause by such court to provide for the
maximum geographic area and duration then permissible.

                               -11-
<PAGE>

                The parties expressly recognize that the geographic scope of
this covenant is substantial in that the nature of the  COMPANY'S business is
done on a national level dealing with national accounts, even though
individual customers maybe local and distinct in nature.  The parties agree
that the COMPANY'S client lists, financial information, production
information, projections and business plans are an asset of substantial value
and that the COMPANY is entitled to protection of this unique asset.

            5.8 Specific Performances.  If the EMPLOYEE commits a breach, or
threatens to commit a breach, of any of the provisions of paragraph 5 the
COMPANY shall have the following rights and remedies:

                5.8.1 The right and remedy to have the provisions of this
Agreement specifically enforced by any court having equity jurisdiction, it
being acknowledged and agreed that any such breach or threatened breach will
cause irreparable injury to the COMPANY and that money damages will not
provide an adequate remedy to the COMPANY; and

                5.8.2 The right and remedy to require the EMPLOYEE, if
directed to do so by any court having equity jurisdiction, to account for and
pay over to the COMPANY all compensation, profits, monies, accruals,
increments or other benefits (collectively "Benefits") derived or received by
the EMPLOYEE as the result of any transactions constituting a breach of any of
the provisions of the preceding paragraph, and the EMPLOYEE hereby agrees to
account for any pay over such Benefits to the COMPANY.

                               -12-

<PAGE>

              Each of the rights and remedies enumerated above shall be
independent of the other, and shall be severally enforceable, and all such
rights and remedies shall be in addition to, and not in lieu of, any other
rights and remedies available to the COMPANY under law or in equity.

            5.9 Unenforceability.  If any of the covenants contained in
Paragraph 5 hereof, or any part thereof, is hereafter construed to be invalid
or unenforceable, the same shall not affect the remainder of the covenant or
covenants, which shall be given full effect, without regard to the invalid
portions.

            If any of the covenants contained in Paragraph 5 or any part
thereof, is held to be unenforceable because of the duration of such provision
or the area covered thereby, the parties agree that the court making such
determination shall have the power to reduce the duration and/or area of such
provision and, in its reduced form, said provision shall then be enforceable.

            5.10 Costs of Suit.  In the event that any action, suit or other
preceding in law or in equity is brought to enforce the covenants contained in
Paragraph 5 or any other provision of this Agreement or to obtain money
damages for the breach thereof, and such action results in the award of a
judgment for money damages or in the granting of any injunction in favor of
the COMPANY, all expenses (including reasonable attorneys fees) of the COMPANY
in such action, suit or other proceeding shall (on demand of the COMPANY) be
paid by EMPLOYEE.

                               -13-

            5.11 Acknowledgment of Proprietary Interest - Customers.  The
EMPLOYEE recognizes and agrees (i) that all existing client lists and client
contracts, production information and financial and business plans of the
COMPANY are and shall be the sole and exclusive property of the COMPANY, and
that the EMPLOYEE neither has nor shall have any right, title or interest
therein; (ii) that such lists and information are not readily accessible to

                      AMENDED AND RESTATED RIGHTS AGREEMENT

         AMENDED AND RESTATED RIGHTS AGREEMENT, dated as of November 16, 2001
(the "Agreement"), between Atrix Laboratories, Inc., a Delaware corporation (the
"Company"), and American Stock Transfer & Trust Company, a New York corporation
(the "Rights Agent").

         WHEREAS, the Company and the Rights Agent entered into a Rights
Agreement dated as of September 25, 1998; and

         WHEREAS, effective September 25, 1998 (the "Rights Dividend Declaration
Date"), the Board of Directors of the Company (i) authorized and declared a
dividend distribution of one Right for each share of the Company's common stock,
par value $.001 per share (the "Company Common Stock") outstanding at the Close
of Business on September 25, 1998 (the "Record Date"), and (ii) authorized the
issuance of one Right (as such number may hereinafter be adjusted pursuant
hereto) for each share of Company Common Stock issued between the Record Date
(whether originally issued or delivered from the Company's treasury) and, except
as otherwise provided in Section 22, the Distribution Date, each Right initially
representing the right to purchase upon the terms and subject to the conditions
hereinafter set forth one Unit of Series A Preferred Stock (the "Rights"); and

         WHEREAS, Section 26 of the Rights Agreement provides that prior to the
Distribution Date (as defined in the Rights Agreement), the Company may
supplement or amend the Rights Agreement in any respect without the approval of
the holders of the Rights; and

         WHEREAS, the Board of Directors of the Company has determined that it
is in the best interest of the Company and the holders of the Company Common
Stock to amend and restate the Rights Agreement as set forth herein, and in
connection therewith the Company is entering into this Amended and Restated
Rights Agreement and directing the Rights Agent to enter into this Amended and
Restated Rights Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

         Section 1. Certain Definitions. For purposes of this Agreement, the
following terms have the meanings indicated:

                  (a) "Acquiring Person" shall mean any Person who or which,
         together with all Affiliates or Associates of such Person, shall be the
         Beneficial Owner of 15% or more of the shares of Company Common Stock
         then outstanding. Notwithstanding the foregoing: (i) an "Acquiring
         Person" shall not include: (A) the Company; (B) any Subsidiary of the
         Company; (C) any employee benefit plan maintained by the Company or any
         of its Subsidiaries; (D) any trustee or fiduciary with respect to such
         employee benefit plan acting in such capacity or a trustee or fiduciary
         holding shares of Company Common Stock for the purpose of funding any
         such plan or employee benefits; (E) any Person if the Board of
         Directors of the Company determines in good faith that such Person who

                                       1
<PAGE>

         would otherwise be an "Acquiring Person" became such inadvertently
         (including, without limitation, because (x) such Person was unaware
         that it beneficially owned a percentage of Company Common Stock that
         would otherwise cause such Person to be an "Acquiring Person" or (y)
         such Person was aware of the extent of its Beneficial Ownership of
         Company Common Stock but had no actual knowledge of the consequences of
         such Beneficial Ownership under this Agreement) and without any
         intention of changing or influencing control of the Company, and if
         such Person does not acquire any additional shares of Company Common
         Stock and as promptly as practicable divested or divests itself of
         Beneficial Ownership of a sufficient number of shares of Company Common
         Stock so that such Person would no longer be an "Acquiring Person;" or
         (F) any Person who becomes the Beneficial Owner of 15% or more of the
         then outstanding shares of Company Common Stock as a result of the
         acquisition of shares of Company Common Stock directly from the Company
         in one or more transactions approved by a majority of the Board of
         Directors, and (ii) no Person shall be deemed an "Acquiring Person" as
         a result of the acquisition of shares of Company Common Stock by the
         Company which, by reducing the number of shares of Company Common Stock
         outstanding, increases the proportional number of shares beneficially
         owned by such Person; provided, however, that if (x) a Person would
         become an Acquiring Person (but for the operation of this subclause
         (ii)) as a result of the acquisition of shares of Company Common Stock
         by the Company and (y) after such share acquisition by the Company,
         such Person becomes the Beneficial Owner of any additional shares of
         Company Common Stock, then such Person shall be deemed an Acquiring
         Person unless, upon becoming the Beneficial Owner of such additional
         shares, such Person is the Beneficial Owner of less than 15% of the
         then outstanding shares of Company Common Stock. Each Person identified
         in subclauses (A), (B), (C) and (D) of this Section (1)(a) is
         individually an "Exempt Person" and collectively "Exempt Persons."

                  (b) "Affiliate" and "Associate" shall have the respective
         meanings ascribed to such terms in Rule 12b-2 of the General Rules and
         Regulations under the Securities Exchange Act of 1934, as amended (the
         "Exchange Act"), as in effect on the date hereof.

                  (c) A Person shall be deemed the "Beneficial Owner" of, and
         shall be deemed to have "Beneficial Ownership" of and to "beneficially
         own", any securities:

                           (i) of which such Person or any of such Person's
                  Affiliates or Associates is considered to be a "beneficial
                  owner" under Rule 13d-3 of the General Rules and Regulations
                  under the Exchange Act (the "Exchange Act Regulations") as in
                  effect on the date hereof; provided, however, that a Person
                  shall not be deemed the "Beneficial Owner" of, or to
                  "beneficially own", any securities under this subparagraph (i)
                  as a result of an agreement, arrangement or understanding to
                  vote such securities if such agreement, arrangement or
                  understanding (A) arises solely from a revocable proxy or
                  consent given in response to a public proxy or consent
                  solicitation made pursuant to, and in accordance with, the
                  applicable provisions of the Exchange Act and the Exchange Act
                  Regulations, and (B) is not reportable by such Person on
                  Schedule 13D under the Exchange Act (or any comparable or
                  successor report);

                                       2

                           (ii) which are beneficially owned, directly or
                  indirectly, by any other Person (or any Affiliate or Associate
                  of such other Person) with which such Person (or any of such
                  Person's Affiliates or Associates) has any agreement,
                  arrangement or understanding (whether or not in writing), for
                  the purpose of acquiring, holding, voting (except pursuant to
                  a revocable proxy or consent as described in the proviso to
                  subparagraph (i) of this paragraph (c)) or disposing of such
                  securities; or

                           (iii) which such Person or any of such Person's
                  Affiliates or Associates, directly or indirectly, has the
                  right to acquire (whether such right is exercisable
                  immediately or only after the passage of time or upon the
                  satisfaction of conditions) pursuant to any agreement,
                  arrangement or understanding (whether or not in writing) or
                  upon the exercise of conversion rights, exchange rights,
                  rights, warrants or options, or otherwise;

         provided, however, that under this paragraph (c) a Person shall not be
         deemed the "Beneficial Owner" of, to have "Beneficial Ownership" of, or
         to "beneficially own", (A) securities tendered pursuant to a tender or
         exchange offer made in accordance with Exchange Act Regulations by such
         Person or any of such Person's Affiliates or Associates until such
         tendered securities are accepted for purchase or exchange, (B)
         securities that may be issued upon exercise of Rights at any time prior
         to the occurrence of a Triggering Event, or (C) securities that may be
         issued upon exercise of Rights from and after the occurrence of a
         Triggering Event, which Rights were acquired by such Person or any of
         such Person's Affiliates or Associates prior to the Distribution Date
         or pursuant to Section 3(c) or Section 22 hereof (the "Original
         Rights") or pursuant to Section 11(i) hereof in connection with an
         adjustment made with respect to any Original Rights; and further
         provided, however, that (x) nothing in this paragraph (c) shall cause a
         Person engaged in business as an underwriter of securities to be the
         "Beneficial Owner" of, or to "beneficially own," any securities
         acquired through such Person's participation in good faith in a firm
         commitment underwriting until the expiration of forty days after the
         date of such acquisition, (y) no decision reached, or action taken, by
         the Board of Directors of the Company or any committee thereof shall
         cause any Person (or any Affiliate or Associate of such Person) who is
         a member of the Board of Directors of the Company or such committee to
         be deemed, for the purposes of this Agreement, to be a Beneficial Owner
         of any securities beneficially owned by any other Person (or any
         Affiliate or Associate of such Person) who is a member of the Board of
         Directors of the Company or any committee thereof solely by reason of
         such membership of the Board of Directors or any committee thereof or
         participation in the decisions or actions thereof on the part of either
         or both of such Persons and (z) no Person who is an officer, director
         or employee of an Exempt Person shall be deemed, solely by reason of
         such Person's status or authority as such, to be the "Beneficial Owner"
         of, to have "Beneficial Ownership" of or to "beneficially own" any
         securities that are "beneficially owned" (as defined in this paragraph
         (c)), including, without limitation, in a fiduciary capacity, by an
         Exempt Person or by any other such officer, director or employee of an
         Exempt Person.

         Section 2. Appointment of Rights Agent. The Company hereby appoints the
Rights Agent to act as agent for the Company in accordance with the terms and
conditions hereof, and the Rights Agent hereby accepts such appointment. With
the consent of the Rights Agent, the Company may from time to time appoint such

         Section 3. Issue of Rights Certificates. (a) Until the earlier of (i)
the Close of Business on the tenth Business Day after the Stock Acquisition
Date, and (ii) the Close of Business on the tenth Business Day (or such later
date as may be determined by action of a majority of the Board of Directors of
the Company prior to the occurrence of a Section 11(a)(ii) Event) after the date
that a tender or exchange offer by any Person (other than an Exempt Person) is
first published or sent or given within the meaning of Rule 14d-4(a) of the
Exchange Act Regulations or any successor rule, if upon consummation thereof
such Person would be an Acquiring Person (including, in the case of both clause

to the issuance of the Rights)(the earlier of (i) and (ii) above being the

provisions of paragraph (b) of this Section 3) by the certificates for shares of
Company Common Stock registered in the names of the holders of shares of Company

shares of Company Common Stock shall be deemed also to be certificates for
Rights) and not by separate certificates, and (y) the Rights will be
transferable only in connection with the transfer of the underlying shares of
Company Common Stock including a transfer to the Company; provided, however,
that if a tender or exchange offer is terminated prior to the occurrence of a
Distribution Date, then no Distribution Date shall occur as a result of such
tender or exchange offer. As soon as practicable after the Distribution Date,
the Rights Agent will send by first-class, insured, postage prepaid mail, to
each record holder of shares of Company Common Stock as of the Close of Business
on the Distribution Date, at the address of such holder shown on the records of
the Company, one or more rights certificates, in substantially the form of
Exhibit A hereto (the "Rights Certificates"), evidencing one Right for each
share of Company Common Stock so held, subject to adjustment as provided herein.

         In the event that an adjustment in the number of Rights per share of
Company Common Stock has been made pursuant to Section 11(p) hereof, at the time
of distribution of the Rights Certificates, the Company may make the necessary
and appropriate rounding adjustments (in accordance with Section 14(a) hereof)
so that Rights Certificates representing only whole numbers of Rights are
distributed and cash is paid in lieu of any fractional Rights. As of and after
the Distribution Date, the Rights will be evidenced solely by such Rights
Certificates.

                  (b) As promptly as practicable following the Record Date, the
Company will send a copy of a Summary of Rights to Purchase Preferred Stock, in
substantially the form attached hereto as Exhibit B (the "Summary of Rights"),
by first-class, postage prepaid mail, to each record holder of shares of Company
Common Stock as of the Close of Business on the Record Date, at the address of
such holder shown on the records of the Company. With respect to certificates
for Company Common Stock outstanding as of the Record Date, until the
Distribution Date, the Rights will be evidenced by such certificates registered
in the names of the holders thereof together with the Summary of Rights. Until
the Distribution Date (or, if earlier, the Expiration Date), the surrender for
transfer of any such certificate for Company Common

                                       6
<PAGE>

Stock outstanding as of the Record Date, with or without a copy of the Summary
of Rights, shall also constitute the transfer of the Rights associated with the
Company Common Stock represented thereby.

                  (c) Rights shall, without any further action, be issued in
respect of all shares of Company Common Stock which are issued (including any
shares of Company Common Stock held in treasury) after the Record Date but prior
to the earlier of the Distribution Date and the Expiration Date. Certificates,
representing such shares of Company Common Stock, issued after the Record Date
shall bear the following legend:

        This certificate also evidences and entitles the holder hereof to
        certain Rights as set forth in the Amended and Restated Rights Agreement
        between Atrix Laboratories, Inc. (the "Company") and American Stock
        Transfer & Trust Company (the "Rights Agent") dated as of November 16,
        2001, as amended from time to time (the "Rights Agreement"), the terms
        of which are hereby incorporated herein by reference and a copy of which
        is on file at the principal office of the stock transfer administration
        office of the Rights Agent. Under certain circumstances, as set forth in
        the Rights Agreement, such Rights will be evidenced by separate
        certificates and will no longer be evidenced by this certificate. The
        Company will mail to the holder of this certificate a copy of the Rights
        Agreement, as in effect on the date of mailing, without charge promptly
        after receipt of a written request therefor. UNDER CERTAIN CIRCUMSTANCES
        SET FORTH IN THE RIGHTS AGREEMENT, RIGHTS ISSUED TO, OR HELD BY, ANY
        PERSON WHO IS, WAS OR BECOMES AN ACQUIRING PERSON OR ANY AFFILIATE OR
        ASSOCIATE THEREOF (AS SUCH TERMS ARE DEFINED IN THE RIGHTS AGREEMENT),
        WHETHER CURRENTLY HELD BY OR ON BEHALF OF SUCH PERSON OR BY ANY
        SUBSEQUENT HOLDER, MAY BECOME NULL AND VOID.

With respect to certificates representing shares of Company Common Stock that
bear the foregoing legend until the earlier of the Distribution Date and the
Expiration Date, the Rights associated with the shares of Company Common Stock
represented by such certificates shall be evidenced by such certificates alone
and registered holders of the shares of Company Common Stock shall also be the
registered holders of the associated Rights, and the transfer of any of such
certificates shall also constitute the transfer of the Rights associated with
the shares of Company Common Stock represented by such certificates.

         Section 4. Form of Rights Certificates. The Rights Certificates (and
the forms of election to purchase, assignment and certificate to be printed on
the reverse thereof) shall each be substantially in the form set forth in
Exhibit A hereto and may have such marks of identification or designation and
such legends, summaries or endorsements printed thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Agreement,
or as may be required to comply with any applicable law or any rule or
regulation thereunder or with any rule or regulation of any stock exchange or
automated quotation system on which the Rights may from time to time be listed
or to conform to usage. Subject to the provisions of Section 11 and Section 22
hereof, the Rights Certificates, whenever distributed, shall be dated as of the
Record Date and on their face shall entitle the holders thereof to purchase such
number of Units of Preferred Stock as shall be set forth therein at the price
set forth therein, but the amount and

                                       7
<PAGE>

type of securities, cash or other assets that may be acquired upon the exercise
of each Right and the Purchase Price thereof shall be subject to adjustment as
provided herein.

         Section 5. Countersignature and Registration . (a) Rights Certificates
shall be executed on behalf of the Company by its Chairman, its President or one
of its Vice Presidents under its corporate seal reproduced thereon attested by
its Secretary, its Treasurer or one of its Assistant Secretaries. The signature
of any of these officers on the Rights Certificates may be manual or facsimile.
Rights Certificates bearing the manual or facsimile signatures of the
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the countersignature of such Rights Certificates or
did not hold such offices at the date of such Rights Certificates. No Rights
Certificate shall be entitled to any benefit under this Agreement or be valid
for any purpose unless there appears on such Rights Certificate a
countersignature duly executed by the Rights Agent by manual signature of an
authorized signatory, and such countersignature upon any Rights Certificate
shall be conclusive evidence, and the only evidence, that such Rights
Certificate has been duly countersigned as required hereunder.

                  (b) Following the Distribution Date, the Rights Agent will
keep or cause to be kept, at its office designated for surrender of Rights
Certificates upon exercise or transfer, books for registration and transfer of
the Rights Certificates issued hereunder. Such books shall show the name and
address of each holder of the Rights Certificates, the number of Rights
evidenced on its face by each Rights Certificate and the date of each Rights
Certificate.

         Section 6. Transfer, Split Up, Combination and Exchange of Rights
Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates. (a)
Subject to the provisions of Sections 4, 7(e) and 14 hereof, at any time after
the Close of Business on the Distribution Date, and at or prior to the Close of
Business on the Expiration Date, any Rights Certificate or Certificates may be
transferred, split up, combined or exchanged for another Rights Certificate or
Certificates, entitling the registered holder to purchase a like number of Units
of Preferred Stock (or, following a Triggering Event, other securities, cash or
other assets, as the case may be) as the Rights Certificate or Certificates
surrendered then entitled such holder to purchase. Any registered holder
desiring to transfer, split up, combine or exchange any Rights Certificate or
Certificates shall make such request in writing delivered to the Rights Agent,
and shall surrender the Rights Certificate or Certificates to be transferred,
split up, combined or exchanged at the office of the Rights Agent designated for
such purpose. Neither the Rights Agent nor the Company shall be obligated to
take any action whatsoever with respect to the transfer of any such surrendered
Rights Certificate until the registered holder shall have completed and executed
the certificate set forth in the form of assignment on the reverse side of such
Rights Certificate and shall have provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) of the Rights
represented by such Rights Certificate or Affiliates or Associates thereof as
the Company shall reasonably request; whereupon the Rights Agent shall, subject
to the provisions of Section 7(e) and Section 14 hereof, countersign and deliver
to the Person entitled thereto a Rights Certificate or Rights Certificates, as
the case may be, as so requested. The Company may require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer, split up, combination or exchange of Rights
Certificates.

                                       8

                  (b) Subject to Section 7(e) hereof, if a Rights Certificate
shall be mutilated, lost, stolen or destroyed, upon request by the registered
holder of the Rights represented thereby and upon payment to the Company and the
Rights Agent of all reasonable expenses incident thereto, there shall be issued,
in exchange for and upon cancellation of the mutilated Rights Certificate, or in
substitution for the lost, stolen or destroyed Rights Certificate, a new Rights
Certificate, in substantially the form of the prior Rights Certificate, of like
tenor and representing the equivalent number of Rights, but, in the case of
loss, theft or destruction, only upon receipt of evidence satisfactory to the
Company and the Rights Agent of such loss, theft or destruction of such Rights
Certificate and, if requested by the Company or the Rights Agent, indemnity also
satisfactory to it.

         Section 7. Exercise of Rights; Purchase Price; Expiration Date of
Rights. (a) Prior to the earlier of (i) the Close of Business on the tenth
anniversary hereof (the "Final Expiration Date"), (ii) the time at which the
Rights are redeemed as provided in Section 23 hereof and (iii) the time at which
the Rights are exchanged as provided in Section 34 hereof (the earlier of (i),
(ii) and (iii) being the "Expiration Date"), the registered holder of any Rights
Certificate may, subject to the provisions of Sections 7(e) and 9(c) hereof,
exercise the Rights evidenced thereby, in whole or in part, at any time after
the Distribution Date upon surrender of the Rights Certificate, with the form of
election to purchase and the certificate on the reverse side thereof duly
executed, to the Rights Agent at the office of the Rights Agent designated for
such purpose, together with payment of the aggregate Purchase Price (as
hereinafter defined) for the number of Units of Preferred Stock (or, following a
Triggering Event, other securities, cash or other assets, as the case may be)
for which such surrendered Rights are then exercisable.

                  (b) The purchase price for each one one-hundredth of a share
(each such one one-hundredth of a share being a "Unit") of Preferred Stock upon
exercise of Rights shall be $67.50, subject to adjustment from time to time as
provided in Sections 11 and 13(a) hereof (such purchase price, as so adjusted,
being the "Purchase Price"), and shall be payable in accordance with paragraph
(c) below.

                  (c) As promptly as practicable following the occurrence of the
Distribution Date, the Company shall deposit with the Rights Agent or other
corporation in good standing organized under the laws of the United States or
any State of the United States, which is authorized under such laws to exercise
corporate trust or stock transfer powers and is subject to supervision or
examination by federal or state authority (such institution being the
"Depositary Agent"), certificates representing the shares of Preferred Stock
that may be acquired upon exercise of the Rights and shall cause such Depositary
Agent to enter into an agreement pursuant to which the Depositary Agent shall
issue receipts representing interests in the shares of Preferred Stock so
deposited. Upon receipt of a Rights Certificate representing exercisable Rights,
with the form of election to purchase and the certificate duly executed,
accompanied by payment, with respect to each Right so exercised, of the Purchase
Price for the Units of Preferred Stock (or, following a Triggering Event, other
securities, cash or other assets, as the case may be) to be purchased thereby as
set forth below and an amount equal to any applicable transfer tax or evidence
satisfactory to the Company of payment of such tax, the Rights Agent shall,
subject to Section 20(k) hereof, thereupon promptly (i) requisition from the
Depositary Agent depositary receipts representing such number of Units of
Preferred Stock as are to be purchased and the Company

                                       9
<PAGE>

will direct the Depositary Agent to comply with such request, (ii) requisition
from the Company the amount of cash, if any, to be paid in lieu of fractional
shares in accordance with Section 14 hereof, (iii) after receipt of such
depositary receipts, cause the same to be delivered to or upon the order of the
registered holder of such Rights Certificate, registered in such name or names
as may be designated by such holder, and (iv) after receipt thereof, deliver
such cash, if any, to or upon the order of the registered holder of such Rights
Certificate. In the event that the Company is obligated to issue Company Common
Stock, other securities of the Company, pay cash and/or distribute other
property pursuant to Section 11(a) hereof, the Company will make all
arrangements necessary so that such Company Common Stock, other securities, cash
and/or other property are available for distribution by the Rights Agent, if and
when appropriate. The payment of the Purchase Price (as such amount may be
reduced pursuant to Section 11(a)(iii) hereof) may be made in cash or by
certified or bank check or money order payable to the order of the Company.

                  (d) In case the registered holder of any Rights Certificate
shall exercise less than all the Rights evidenced thereby, a new Rights
Certificate evidencing the Rights remaining unexercised shall be issued by the
Rights Agent and delivered to, or upon the order of, the registered holder of
such Rights Certificate, registered in such name or names as may be designated
by such holder, subject to the provisions of Section 14 hereof.

                  (e) Notwithstanding anything in this Agreement to the
contrary, from and after the first occurrence of any Section 11(a)(ii) Event,
any Rights beneficially owned by (i) an Acquiring Person or an Associate or
Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or
of any such Associate or Affiliate) which becomes a transferee after the
Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person (or
of any such Associate or Affiliate) which becomes a transferee prior to or
concurrently with the Acquiring Person becoming such and which receives such
Rights pursuant to either (A) a transfer (whether or not for consideration) from
the Acquiring Person (or any such Associate or Affiliate) to holders of equity
interests in such Acquiring Person (or any such Associate or Affiliate) or to
any Person with whom the Acquiring Person (or such Associate or Affiliate) has
any continuing agreement, arrangement or understanding regarding the transferred
Rights, shares of Company Common Stock or the Company or (B) a transfer which
the Board of Directors has determined to be part of a plan, arrangement or
understanding which has as a primary purpose or effect the avoidance of this
Section 7(e), shall be null and void without any further action, and no holder
of such Rights shall have any rights whatsoever with respect to such Rights,
whether under any provision of this Agreement or otherwise. The Company shall
use all reasonable efforts to ensure that the provisions of this Section 7(e)
hereof are complied with, but shall have no liability to any holder of Rights or
any other Person as a result of its failure to make any determination under this
Section 7(e) with respect to an Acquiring Person or its Affiliates, Associates
or transferees.

                  (f) Notwithstanding anything in this Agreement or any Rights
Certificate to the contrary, neither the Rights Agent nor the Company shall be
obligated to undertake any action with respect to a registered holder upon the
occurrence of any purported exercise by such registered holder unless such
registered holder shall have (i) completed and executed the certificate
following the form of election to purchase set forth on the reverse side of the
Rights Certificate surrendered for such exercise, and (ii) provided such
additional evidence of the

                                       10
<PAGE>

identity of the Beneficial Owner (or former Beneficial Owner) of the Rights
represented by such Rights Certificate or Affiliates or Associates thereof as
the Company shall reasonably request.

         Section 8. Cancellation and Destruction of Rights Certificates. All
Rights Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or any of its
agents, be delivered to the Rights Agent for cancellation or in cancelled form,
or, if surrendered to the Rights Agent, shall be cancelled by it, and no Rights
Certificates shall be issued in lieu thereof except as expressly permitted by
this Agreement. The Company shall deliver to the Rights Agent for cancellation
and retirement, and the Rights Agent shall so cancel and retire, any Rights
Certificates acquired by the Company otherwise than upon the exercise thereof.
The Rights Agent shall deliver all cancelled Rights Certificates to the Company,
or shall, at the written request of the Company, destroy such cancelled Rights
Certificates, and in such case shall deliver a certificate of destruction
thereof to the Company.

         Section 9. Reservation and Availability of Capital Stock. (a) The
Company shall at all times prior to the Expiration Date cause to be reserved and
kept available, out of its authorized and unissued shares of preferred stock,
the number of shares of Preferred Stock that, as provided in this Agreement,
will be sufficient to permit the exercise in full of all outstanding Rights.
Upon the occurrence of any events resulting in an increase in the aggregate
number of shares of Preferred Stock (or other equity securities of the Company)
issuable upon exercise of all outstanding Rights above the number then reserved,
the Company shall make appropriate increases in the number of shares so reserved
to the extent practicable.

                  (b) If the shares of Preferred Stock to be issued and
delivered upon the exercise of the Rights may be listed on any national
securities exchange or automated quotation system, the Company shall during the
period from the Distribution Date through the Expiration Date use its best
efforts to cause all securities reserved for such issuance to be listed on such
exchange upon official notice of issuance upon such exercise.

                  (c) The Company shall use its best efforts (i) as soon as
practicable following the occurrence of a Section 11(a)(ii) Event and a
determination by the Company in accordance with Section 11(a)(iii) hereof of the
consideration to be delivered by the Company upon exercise of the Rights or, if
so required by law, as soon as practicable following the Distribution Date (such
date being the "Registration Date"), to file a registration statement on an
appropriate form under the Securities Act of 1933, as amended (the "Securities
Act"), with respect to the securities that may be acquired upon exercise of the
Rights (the "Registration Statement"), (ii) to cause the Registration Statement
to become effective as soon as practicable after such filing, (iii) to cause the
Registration Statement to continue to be effective (and to include a prospectus
complying with the requirements of the Securities Act) until the earlier of (A)
the date as of which the Rights are no longer exercisable for the securities
covered by the Registration Statement, and (B) the Expiration Date, and (iv) to
take as soon as practicable following the Registration Date such action as may
be required to ensure that any acquisition of securities upon exercise of the
Rights complies with any applicable state securities or "blue sky" laws. The
Company may temporarily suspend, for a period of time not to exceed one hundred
twenty (120) days after the date set forth in clause (i) of the first sentence
of this Section 9(c), the exercisability of the Rights in order to

                                       11
<PAGE>

prepare and file such registration statement and permit it to become effective.
Upon any such suspension, the Company shall issue a public announcement stating
that the exercisability of the Rights has been temporarily suspended, as well as
a public announcement at such time as the suspension is no longer in effect. In
addition, if the Company shall determine that a registration statement is
required following the Distribution Date, the Company may temporarily suspend
the exercisability of the Rights until such time as a registration statement has
been declared effective. Notwithstanding any provision of this Agreement to the
contrary, the Rights shall not be exercisable in any jurisdiction if the
requisite qualification in such jurisdiction shall not have been obtained, the
exercise thereof shall not be permitted under applicable law or a registration
statement shall not have been declared effective.

                  (d) The Company shall take such action as may be necessary to
ensure that all shares of Preferred Stock (and, following the occurrence of a
Triggering Event, any other securities that may be delivered upon exercise of
Rights) shall be, at the time of delivery of the certificates or depositary
receipts for such securities (subject to payment of the Purchase Price), duly
and validly authorized and issued and fully paid and non-assessable.

                  (e) The Company shall pay any documentary, stamp or transfer
tax imposed in connection with the issuance or delivery of the Rights
Certificates or upon the exercise of Rights; provided, however, the Company
shall not be required to pay any such tax imposed in connection with the
issuance or delivery of Units of Preferred Stock, or any certificates or
depositary receipts for such Units of Preferred Stock (or, following the
occurrence of a Triggering Event, any other securities, cash or assets, as the
case may be) to any person other than the registered holder of the Rights
Certificates evidencing the Rights surrendered for exercise. The Company shall
not be required to issue or deliver any certificates or depositary receipts for
Units of Preferred Stock (or, following the occurrence of a Triggering Event,
any other securities, cash or assets, as the case may be) to, or in a name other
than that of, the registered holder upon the exercise of any Rights until any
such tax shall have been paid (any such tax being payable by the holder of such
Rights Certificate at the time of surrender) or until it has been established to
the Company's satisfaction that no such tax is due.

         Section 10. Preferred Stock Record Date. Each Person in whose name any
certificate or depositary receipt for Units of Preferred Stock (or, following
the occurrence of a Triggering Event, other securities) is issued upon the
exercise of Rights shall for all purposes be deemed to have become the holder of
record of the Units of Preferred Stock (or, following the occurrence of a
Triggering Event, other securities) represented thereby on, and such certificate
shall be dated, the date upon which the Rights Certificate evidencing such
Rights was duly surrendered and payment of the Purchase Price (and any
applicable transfer taxes) was made; provided, however, that if the date of such
surrender and payment is a date upon which the Preferred Stock (or, following
the occurrence of a Triggering Event, other securities) transfer books of the
Company are closed, such Person shall be deemed to have become the record holder
of such securities on, and such certificate shall be dated, the next succeeding
Business Day on which the Preferred Stock (or, following the occurrence of a
Triggering Event, other securities) transfer books of the Company are open and,
further provided, however, that if delivery of Units of Preferred Stock is
delayed pursuant to Section 9(c) hereof, such Persons shall be deemed to have
become the record holders of such Units of Preferred Stock only when such Units
first become deliverable. Prior to

                                       12
<PAGE>

the exercise of the Rights evidenced thereby, the holder of a Rights Certificate
shall not be entitled to any rights of a stockholder of the Company with respect
to securities for which the Rights shall be exercisable, including, without
limitation, the right to vote, to receive dividends or other distributions or to
exercise any preemptive rights, and shall not be entitled to receive any notice
of any proceedings of the Company, except as provided herein.

         Section 11. Adjustment of Purchase Price, Number and Kind of Shares or
Number of Rights. The Purchase Price, the number and kind of securities
purchasable upon exercise of each Right and the number of Rights outstanding are
subject to adjustment from time to time as provided in this Section 11.

                  (a) (i) In the event the Company shall at any time after the
         date of this Agreement (A) declare a dividend on the Preferred Stock
         payable in shares of Preferred Stock, (B) subdivide the outstanding
         Preferred Stock, (C) combine the outstanding Preferred Stock into a
         smaller number of shares, or (D) issue any shares of its capital stock
         in a reclassification of the Preferred Stock (including any such
         reclassification in connection with a consolidation or merger in which
         the Company is the continuing or surviving corporation), except as
         otherwise provided in this Section 11(a), the Purchase Price in effect
         at the time of the record date for such dividend or of the effective
         date of such subdivision, combination or reclassification, and the
         number and kind of shares of Preferred Stock or capital stock, as the
         case may be, issuable on such date upon exercise of the Rights, shall
         be proportionately adjusted so that the holder of any Right exercised
         after such time shall be entitled to receive, upon payment of the
         Purchase Price then in effect, the aggregate number and kind of shares
         of Preferred Stock or capital stock, as the case may be, which, if such
         Right had been exercised immediately prior to such date, such holder
         would have owned upon such exercise and been entitled to receive by
         virtue of such dividend, subdivision, combination or reclassification;
         provided, however, that in no event shall the consideration to be paid
         upon the exercise of one Right be less than the aggregate par value of
         the shares of capital stock of the Company issuable upon the exercise
         of one Right. If an event occurs which would require an adjustment
         under both this Section 11(a)(i) and Section 11(a)(ii) hereof, the
         adjustment provided for in this Section 11(a)(i) shall be in addition
         to, and shall be made prior to, any adjustment required pursuant to
         Section 11(a)(ii) hereof.

                  (ii) In the event any Person shall become an Acquiring Person,
         other than pursuant to any transaction set forth in Section 13(a)
         hereof, then, immediately upon the occurrence of such event (a "Section
         11(a)(ii) Event"), proper provision shall be made so that each holder
         of a Right (except as provided below and in Section 7(e) hereof) shall,
         subject to Section 34 hereof, thereafter have the right to receive,
         upon exercise of such Right at the then current Purchase Price in
         accordance with the terms of this Agreement, in lieu of the number of
         Units of Preferred Stock for which a Right was exercisable immediately
         prior to the first occurrence of a Section 11(a)(ii) Event (whether or
         not such Right was then exercisable), such number of Units of Preferred
         Stock as shall equal the result obtained by (x) multiplying the then
         current Purchase Price by the then number of Units of Preferred Stock
         for which a Right was exercisable immediately prior to the first
         occurrence of a Section 11(a)(ii) Event (whether or not such Right was
         then exercisable) (such product

                                       13
<PAGE>

         thereafter being, for all purposes of this Agreement, other than
         Section 13 hereof, the "Purchase Price"), and (y) dividing that product
         by 50% of the then current market price (determined pursuant to Section
         11(d) hereof) per Unit of Preferred Stock on the date of such first
         occurrence (such Units of Preferred Stock being the "Adjustment
         Shares"); provided, however, that the Purchase Price and the number of
         Units of Preferred Stock so receivable upon exercise of a Right shall,
         following the Section 11(a)(ii) Event, be subject to further adjustment
         as appropriate in accordance with Section 11 hereof. Notwithstanding
         the foregoing, the Rights shall not be exercisable pursuant to this
         Section 11(a)(ii) until the time period during which the Rights may be
         redeemed pursuant to Section 23 hereof shall have expired.

                  (iii) The Company, by the vote of a majority of the Board of
         Directors, may at its option substitute for a Unit of Preferred Stock
         issuable upon the exercise of Rights in accordance with the foregoing
         subparagraph (ii), shares of Company Common Stock or fractions thereof
         having a current market price (as determined by Section 11(d) hereof)
         equal to the current market price of a Unit of Preferred Stock on the
         date of the Section 11(a)(ii) Event. In the event that the number of
         shares of Preferred Stock which are authorized by the Company's Amended
         and Restated Certificate of Incorporation but not outstanding or
         reserved for issuance for purposes other than upon exercise of the
         Rights is not sufficient to permit the exercise in full of the Rights
         in accordance with the foregoing subparagraph (ii) of this Section
         11(a), the Company, by the vote of a majority of the Board of
         Directors, shall to the extent permitted by applicable law and any
         material agreements then in effect to which the Company is a party or
         by which it is bound: (A) determine the excess of (1) the value of the
         Adjustment Shares issuable upon the exercise of a Right (the "Current
         Value") over (2) the Purchase Price (such excess being the "Spread"),
         and (B) with respect to each Right (other than Rights which have become
         void pursuant to Section 7(e)), make adequate provision to substitute,
         in whole or in part, for such Adjustment Shares, upon exercise of a
         Right and payment of the applicable Purchase Price, (1) cash, (2) a
         reduction in the Purchase Price, (3) shares of Company Common Stock or
         other equity securities of the Company (including, without limitation,
         shares, or units of shares, of preferred stock (such other shares being
         "common stock equivalents")), (4) debt securities of the Company, (5)
         other assets, or (6) any combination of the foregoing, having an
         aggregate value which, when added to the value of the Units of
         Preferred Stock actually issued upon exercise of such Right, shall have
         an aggregate value equal to the Current Value (less the amount of any
         reduction in such Purchase Price), where such aggregate value has been
         determined by a majority of the Board of Directors, after receiving
         advice from a nationally recognized investment banking firm; provided,
         however, that if the Company shall not have made adequate provision to
         deliver value pursuant to clause (B) above within thirty days following
         the later of (x) the first occurrence of a Section 11(a)(ii) Event and
         (y) the date on which the Company's right of redemption pursuant to
         Section 23(a) expires (the later of (x) and (y) being referred to
         herein as the "Section 11(a)(iii) Trigger Date"), then, subject to
         Section 34 hereof, the Company shall be obligated (to the extent
         permitted by applicable law and any material agreements then in effect
         to which the Company is a party or by which it is bound) to deliver,
         upon the surrender for exercise of a Right and without requiring

                                       14
<PAGE>

         payment of the Purchase Price, Units of Preferred Stock (to the extent
         available) and then, if necessary, shares (or fractions of shares, at
         the discretion of the Board of Directors) of Company Common Stock, cash
         or a combination thereof, which Units of Preferred Stock, shares (or
         fractions of shares) of Company Common Stock and/or cash shall have an
         aggregate value equal to the Spread; further provided, however, that if
         the Company is unable to comply with the immediately foregoing
         provision within such thirty day period, then the Company shall (to the
         extent permitted by law) take all such action as may be necessary to
         comply with such provision, including the calling of a meeting of
         stockholders to authorize additional shares of Preferred Stock or
         Company Common Stock. To the extent that the Company determines that
         some action need be taken pursuant to the first sentence of this
         Section 11(a)(iii), the Company shall provide, subject to Section 7(e)
         hereof, that such action shall apply uniformly to all outstanding
         Rights. For purposes of this Section 11(a)(iii), the value of a Unit of
         Preferred Stock or share of Company Common Stock shall be the current
         market price (as determined pursuant to Section 11(d) hereof) per Unit
         of Preferred Stock or share of Company Common Stock, as the case may
         be, on the Section 11(a)(iii) Trigger Date and the value of any common
         stock equivalent shall be deemed to have the same value as the
         Preferred Stock on such date.

                  (b) In case the Company shall fix a record date for the
         issuance of rights, options or warrants to all holders of Preferred
         Stock entitling them to subscribe for or purchase (for a period
         expiring within forty-five calendar days after such record date) shares
         of Preferred Stock (or shares having substantially the same rights,
         privileges and preferences as shares of Preferred Stock ("Equivalent
         Preferred Stock")) or securities convertible into Preferred Stock or
         Equivalent Preferred Stock at a price per share of Preferred Stock or
         per share of Equivalent Preferred Stock (or having a conversion price
         per share, if a security convertible into Preferred Stock or Equivalent
         Preferred Stock) less than the current market price (as determined
         pursuant to Section 11(d) hereof) per share of Preferred Stock on such
         record date, the Purchase Price to be in effect after such record date
         shall be determined by multiplying the Purchase Price in effect
         immediately prior to such record date by a fraction, the numerator of
         which shall be the sum of the number of shares of Preferred Stock
         outstanding on such record date plus the number of shares of Preferred
         Stock which the aggregate offering price of the total number of shares
         of Preferred Stock and/or Equivalent Preferred Stock so to be offered
         (and/or the aggregate initial conversion price of the convertible
         securities so to be offered) would purchase at such current market
         price, and the denominator of which shall be the number of shares of
         Preferred Stock outstanding on such record date plus the number of
         additional shares of Preferred Stock and/or Equivalent Preferred Stock
         to be offered for subscription or purchase (or into which the
         convertible securities so to be offered are initially convertible). In
         case such subscription price may be paid by delivery of consideration
         part or all of which may be in a form other than cash, the value of
         such consideration shall be as determined in good faith by a majority
         of the Board of Directors, whose determination shall be described in a
         statement filed with the Rights Agent and shall be binding on the
         Rights Agent and the holders of the Rights. Shares of Preferred Stock
         owned by or held for the account of the Company or any Subsidiary shall
         not be deemed outstanding for the

                                       15
<PAGE>

         purpose of any such computation. Such adjustment shall be made
         successively whenever such a record date is fixed, and in the event
         that such rights, options or warrants are not so issued, the Purchase
         Price shall be adjusted to be the Purchase Price which would then be in
         effect if such record date had not been fixed.

                  (c) In case the Company shall fix a record date for a
         distribution to all holders of shares of Preferred Stock (including any
         such distribution made in connection with a consolidation or merger in
         which the Company is the continuing or surviving corporation) of
         evidences of indebtedness, cash (other than a regular quarterly cash
         dividend paid out of funds legally available therefor), assets (other
         than a dividend payable in shares of Preferred Stock, but including any
         dividend payable in stock other than Preferred Stock) or subscription
         rights, options or warrants (excluding those referred to in Section
         11(b) hereof), the Purchase Price to be in effect after such record
         date shall be determined by multiplying the Purchase Price in effect
         immediately prior to such record date by a fraction, the numerator of
         which shall be the current market price (as determined pursuant to
         Section 11(d) hereof) per share of Preferred Stock on such record date
         less the fair market value (as determined in good faith by a majority
         of the Board of Directors, whose determination shall be described in a
         statement filed with the Rights Agent and shall be binding on the
         Rights Agent and the holder of the Rights) of the cash, assets or
         evidences of indebtedness so to be distributed or of such subscription
         rights, options or warrants distributable in respect of a share of
         Preferred Stock and the denominator of which shall be such current
         market price (as determined pursuant to Section 11(d) hereof) per share
         of Preferred Stock. Such adjustments shall be made successively
         whenever such a record date is fixed, and in the event that such
         distribution is not so made, the Purchase Price shall be adjusted to be
         the Purchase Price which would have been in effect if such record date
         had not been fixed.

                  (d) (i) For the purpose of any computation hereunder, the
         "current market price" per share of Company Common Stock or Common
         Stock on any date shall be deemed to be the average of the daily
         closing prices per share of such shares for the ten consecutive Trading
         Days (as such term is hereinafter defined) immediately prior to such
         date; provided, however, if prior to the expiration of such requisite
         ten Trading Day period the issuer announces either (A) a dividend or
         distribution on such shares payable in such shares or securities
         convertible into such shares (other than the Rights), or (B) any
         subdivision, combination or reclassification of such shares, then,
         following the ex-dividend date for such dividend or the record date for
         such subdivision, combination or reclassification, as the case may be,
         the "current market price" shall be properly adjusted to take into
         account such event. The closing price for each day shall be, if the
         shares are listed and admitted to trading on a national securities
         exchange, as reported in the principal consolidated transaction
         reporting system with respect to securities listed on the principal
         national securities exchange on which such shares are listed or
         admitted to trading or, if such shares are not listed or admitted to
         trading on any national securities exchange, the last quoted price or,
         if not so quoted, the average of the high bid and low asked prices in
         the over-the-counter market, as reported by the Nasdaq National Market
         ("Nasdaq") or such other system then in use, or, if on any such date
         such shares are not quoted by any such organization, the average of the
         closing bid and asked prices as

                                       16
<PAGE>

         furnished by a professional market maker making a market in such shares
         selected by a majority of the Board of Directors. If on any such date
         no market maker is making a market in such shares, the fair value of
         such shares on such date as determined in good faith by a majority of
         the Board of Directors shall be used. If such shares are not publicly
         held or not so listed or traded, "current market price" per share shall
         mean the fair value per share as determined in good faith by a majority
         of the Board of Directors, whose determination shall be described in a
         statement filed with the Rights Agent and shall be conclusive for all
         purposes. The term "Trading Day" shall mean, if such shares are listed
         or admitted to trading on any national securities exchange, a day on
         which the principal national securities exchange on which such shares
         are listed or admitted to trading is open for the transaction of
         business or, if such shares are not so listed or admitted, a Business
         Day.

                           (ii) For the purpose of any computation hereunder,
         the "current market price" per share of Preferred Stock shall be
         determined in the same manner as set forth above for Company Common
         Stock in clause (i) of this Section 11(d) (other than the fourth
         sentence thereof). If the current market price per share of Preferred
         Stock cannot be determined in the manner provided above or if the
         Preferred Stock is not publicly held or listed or traded in a manner
         described in clause (i) of this Section 11(d), the "current market
         price" per share of Preferred Stock shall be conclusively deemed to be
         an amount equal to 100 (as such amount may be appropriately adjusted
         for such events as stock splits, stock dividends and recapitalizations
         with respect to Company Common Stock occurring after the date of this
         Agreement) multiplied by the current market price per share of Company
         Common Stock. If neither Company Common Stock nor Preferred Stock is
         publicly held or so listed or traded, "current market price" per share
         of the Preferred Stock shall mean the fair value per share as
         determined in good faith by a majority of the Board of Directors, whose
         determination shall be described in a statement filed with the Rights
         Agent and shall be binding on the Rights Agent and the holders of the
         Rights. For all purposes of this Agreement, the "current market price"
         of a Unit of Preferred Stock shall be equal to the "current market
         price" of one share of Preferred Stock divided by 100.

                  (e) Anything herein to the contrary notwithstanding, no
         adjustment in the Purchase Price shall be required unless such
         adjustment would require an increase or decrease of at least 1% in the
         Purchase Price; provided, however, that any adjustments which by reason
         of this Section 11(e) are not required to be made shall be carried
         forward and taken into account in any subsequent adjustment. All
         calculations under this Section 11 shall be made to the nearest cent or
         to the nearest one-hundredth of a share of Company Common Stock or
         Common Stock or other share or ten-thousandth of a share of Preferred
         Stock, as the case may be. Notwithstanding the first sentence of this
         Section 11(e), any adjustment required by this Section 11 shall be made
         no later than the earlier of (i) three years from the date of the
         transaction which mandates such adjustment and (ii) the Expiration
         Date.

                  (f) If as a result of an adjustment made pursuant to Section
         11(a)(ii) or 13(a) hereof, the holder of any Right thereafter exercised
         shall become entitled to receive any

                                       17
<PAGE>

         shares of capital stock other than Preferred Stock, thereafter the
         number of such other shares so receivable upon exercise of any Right
         and the Purchase Price thereof shall be subject to adjustment from time
         to time in a manner and on terms as nearly equivalent as practicable to
         the provisions with respect to the Preferred Stock contained in
         Sections 11(a), (b), (c), (d), (e), (g), (h), (i), (j), (k), (l) and
         (m), and the provisions of Sections 7, 9, 10, 13 and 14 hereof with
         respect to the Preferred Stock shall apply on like terms to any such
         other shares.

                  (g) All Rights originally issued by the Company subsequent to
         any adjustment made to the Purchase Price hereunder shall evidence the
         right to purchase, at the adjusted Purchase Price, the number of Units
         of Preferred Stock (or other securities or amount of cash or
         combination thereof) that may be acquired from time to time hereunder
         upon exercise of the Rights, all subject to further adjustment as
         provided herein.

                  (h) Unless the Company shall have exercised its election as
         provided in Section 11(i), upon each adjustment of the Purchase Price
         as a result of the calculations made in Sections 11(b) and (c), each
         Right outstanding immediately prior to the making of such adjustment
         shall thereafter evidence the right to purchase, at the adjusted
         Purchase Price, that number of Units of Preferred Stock (calculated to
         the nearest one ten-thousandth of a Unit) obtained by (i) multiplying
         (x) the number of Units of Preferred Stock covered by a Right
         immediately prior to this adjustment by (y) the Purchase Price in
         effect immediately prior to such adjustment of the Purchase Price and
         (ii) dividing the product so obtained by the Purchase Price in effect
         immediately after such adjustment of the Purchase Price.

                  (i) The Company may elect on or after the date of any
         adjustment of the Purchase Price to adjust the number of Rights, in
         lieu of any adjustment in the number of Units of Preferred Stock that
         may be acquired upon the exercise of a Right. Each of the Rights
         outstanding after the adjustment in the number of Rights shall be
         exercisable for the number of Units of Preferred Stock for which a
         Right was exercisable immediately prior to such adjustment. Each Right
         held of record prior to such adjustment of the number of Rights shall
         become that number of Rights (calculated to the nearest one
         ten-thousandth) obtained by dividing the Purchase Price in effect
         immediately prior to adjustment of the Purchase Price by the Purchase
         Price in effect immediately after adjustment of the Purchase Price. The
         Company shall make a public announcement of its election to adjust the
         number of Rights, indicating the record date for the adjustment, and,
         if known at the time, the amount of the adjustment to be made. This
         record date may be the date on which the Purchase Price is adjusted or
         any day thereafter, but, if the Rights Certificates have been issued,
         shall be at least ten days later than the date of such public
         announcement. If Rights Certificates have been issued, upon each
         adjustment of the number of Rights pursuant to this Section 11(i), the
         Company shall, as promptly as practicable, cause to be distributed to
         holders of record of Rights Certificates on such record date Rights
         Certificates evidencing, subject to Section 14 hereof, the additional
         Rights to which such holders shall be entitled as a result of such
         adjustment, or, at the option of the Company, shall cause to be
         distributed to such holders of record in substitution and replacement
         for the Rights Certificates held by such holders prior to the date of
         adjustment, and upon surrender thereof, if required by the Company, new
         Rights Certificates evidencing all the

                                       18
<PAGE>

         Rights to which such holders shall be entitled after such adjustment.
         Rights Certificates to be so distributed shall be issued, executed and
         countersigned in the manner provided for herein (and may bear, at the
         option of the Company, the adjusted Purchase Price) and shall be
         registered in the names of the holders of record of Rights Certificates
         on the record date specified in the public announcement.

                  (j) Irrespective of any adjustment or change in the Purchase
         Price or the number of Units of Preferred Stock issuable upon the
         exercise of the Rights, the Rights Certificates theretofore and
         thereafter issued may continue to express the Purchase Price per Unit
         and the number of Units of Preferred Stock which were expressed in the
         Initial Rights Certificates issued hereunder.

                  (k) Before taking any action that would cause an adjustment
         reducing the Purchase Price below the then par value of the number of
         Units of Preferred Stock issuable upon exercise of the Rights, the
         Company shall take any corporate action which may, in the opinion of
         its counsel, be necessary in order that the Company may validly and
         legally issue such fully paid and non-assessable number of Units of
         Preferred Stock at such adjusted Purchase Price.

                  (1) In any case in which this Section 11 shall require that an
         adjustment in the Purchase Price be made effective as of a record date
         for a specified event, the Company may elect to defer until the
         occurrence of such event the issuance to the holder of any Right
         exercised after such record date of that number of Units of Preferred
         Stock and shares of other capital stock or securities of the Company,
         if any, issuable upon such exercise over and above the number of Units
         of Preferred Stock and shares of other capital stock or securities of
         the Company, if any, issuable upon such exercise on the basis of the
         Purchase Price in effect prior to such adjustment; provided, however,
         that the Company shall deliver to such holder a due bill or other
         appropriate instrument evidencing such holder's right to receive such
         additional shares (fractional or otherwise) or securities upon the
         occurrence of the event requiring such adjustment.

                  (m) Anything in this Section 11 to the contrary
         notwithstanding, the Company shall be entitled to make such reductions
         in the Purchase Price, in addition to those adjustments expressly
         required by this Section 11, as and to the extent that in their good
         faith judgment a majority of the Board of Directors shall determine to
         be advisable in order that any (i) consolidation or subdivision of the
         Preferred Stock, (ii) issuance wholly for cash of any shares of
         Preferred Stock at less than the current market price, (iii) issuance
         wholly for cash of shares of Preferred Stock or securities which by
         their terms are convertible into or exchangeable for shares of
         Preferred Stock, (iv) stock dividends or (v) issuance of rights,
         options or warrants referred to in this Section 11, hereafter made by
         the Company to holders of its Preferred Stock, shall not be taxable to
         such holders or shall reduce the taxes payable by such holders.

                  (n) The Company shall not, at any time after the Distribution
         Date, (i) consolidate with any other Person (other than a wholly owned
         Subsidiary of the Company in a transaction which complies with Section
         11(o) hereof), (ii) merge with or into any other

                                       19
<PAGE>

         Person (other than a wholly owned Subsidiary of the Company in a
         transaction which complies with Section 11(o) hereof), or (iii) sell or
         transfer (or permit any Subsidiary to sell or transfer), in one
         transaction, or a series of transactions, assets or earning power
         aggregating more than 50% of the assets or earning power of the Company
         and its Subsidiaries (taken as a whole) to any other Person or Persons
         (other than the Company and/or any of its Subsidiaries in one or more
         transactions each of which complies with Section 11(o) hereof), if (x)
         at the time of or immediately after such consolidation, merger or sale
         there are any rights, warrants or other instruments or securities
         outstanding or agreements in effect which would substantially diminish
         or otherwise eliminate the benefits intended to be afforded by the
         Rights or (y) prior to, simultaneously with or immediately after such
         consolidation, merger or sale, the Person which constitutes, or would
         constitute, the "Principal Party" for purposes of Section 13(a) hereof
         shall have distributed or otherwise transferred to its shareholders or
         other persons holding an equity interest in such Person Rights
         previously owned by such Person or any of its Affiliates and
         Associates; provided, however, this Section 11(n) shall not affect the
         ability of any wholly owned Subsidiary of the Company to consolidate
         with, merge with or into, or sell or transfer assets or earning power
         to, any other wholly owned Subsidiary of the Company.

                  (o) After the Distribution Date, the Company shall not, except
         as permitted by Section 23, Section 26 or Section 34 hereof, take (or
         permit any Subsidiary to take) any action if at the time such action is
         taken it is reasonably foreseeable that such action will diminish
         substantially or otherwise eliminate the benefits intended to be
         afforded by the Rights.

                  (p) Anything in this Agreement to the contrary
         notwithstanding, in the event that the Company shall at any time after
         the Rights Dividend Declaration Date and prior to the Distribution Date
         (i) declare a dividend on the outstanding shares of Company Common
         Stock payable in shares of Company Common Stock, (ii) subdivide the
         outstanding shares of Company Common Stock, (iii) combine the
         outstanding shares of Company Common Stock into a smaller number of
         shares, or (iv) issue any shares of its capital stock in a
         reclassification of Company Common Stock (including any such
         reclassification in connection with a consolidation or merger in which
         the Company is the continuing or surviving corporation), the number of
         Rights associated with each share of Company Common Stock then
         outstanding, or issued or delivered thereafter prior to the
         Distribution Date or in accordance with Section 22 hereof, shall be
         proportionately adjusted so that the number of Rights thereafter
         associated with each share of Company Common Stock following any such
         event shall equal the result obtained by multiplying the number of
         Rights associated with each share of Company Common Stock immediately
         prior to such event by a fraction the numerator of which shall be the
         total number of shares of Company Common Stock outstanding immediately
         prior to the occurrence of the event and the denominator of which shall
         be the total number of shares of Company Common Stock outstanding
         immediately following the occurrence of such event.

         Section 12. Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an adjustment is made as provided in Section 11 or Section 13 hereof,
the Company shall (a) promptly prepare a certificate setting forth such
adjustment and a brief statement of the facts accounting for such adjustment,
(b) promptly file with the Rights Agent, and with each transfer agent for the
Preferred Stock and the Company Common Stock, a copy of such certificate, and
(c) mail a brief summary thereof to each holder of a Rights Certificate (or, if
prior to the Distribution Date, to each holder of a certificate representing
shares of Company Common Stock) in accordance with Section 25 hereof. The Rights
Agent shall be fully protected in relying on any such certificate and on any
adjustment therein contained and shall not be deemed to have knowledge of any
such adjustment unless and until it shall have received such certificate.

         Section 13. Consolidation, Merger or Sale or Transfer of Assets or
Earning Power. (a) In the event that, following the first occurrence of a
Section 11(a)(ii) Event, directly or indirectly, either (x) the Company shall
consolidate with, or merge with and into, any other Person (other than a wholly
owned Subsidiary of the Company in a transaction which complies with Section
11(o) hereof), and the Company shall not be the continuing or surviving
corporation of such consolidation or merger, (y) any Person (other than a wholly
owned Subsidiary of the Company in a transaction which complies with Section
11(o) hereof) shall consolidate with, or merge with or into, the Company, and
the Company shall be the continuing or surviving corporation of such
consolidation or merger and, in connection with such consolidation or merger,
all or part of the outstanding shares of Company Common Stock shall be changed
into or exchanged for stock or other securities of the Company or any other
Person or cash or any other property, or (z) the Company shall sell or otherwise
transfer (or one or more of its Subsidiaries shall sell or otherwise transfer)
to any Person or Persons (other than the Company or any of its wholly owned
Subsidiaries in one or more transactions each of which complies with Section
11(o) hereof), in one or more transactions, assets or earning power aggregating
50% or more of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) (any such event being a "Section 13 Event"), then, and in
each such case, proper provision shall be made so that: (i) each holder of a
Right, (other than Rights which have become void as provided in Section 7(e)
hereof), shall thereafter have the right to receive, upon the exercise thereof
at the then current Purchase Price, in accordance with this Agreement and in
lieu of Units of Preferred Stock or shares of Company Common Stock, such number
of validly authorized and issued, fully paid, non-assessable and freely tradable
shares of Common Stock of the Principal Party (as such term is hereinafter
defined), which shares shall not be subject to any liens, encumbrances, rights
of call or first refusal, transfer restrictions or other adverse claims, as
shall be equal to the result obtained by (1) multiplying the then current
Purchase Price by the number of Units of Preferred Stock for which a Right is
exercisable immediately prior to the first occurrence of a Section 13 Event (or,
if a Section 11(a)(ii) Event has occurred prior to the first occurrence of a
Section 13 Event, multiplying the number of such Units for which a Right would
be exercisable hereunder but for the occurrence of such Section 11(a)(ii) Event
by the Purchase Price which would be in effect hereunder but for such first
occurrence) and (2) dividing that product (which, following the first occurrence
of a Section 13 Event, shall be the "Purchase Price" for all purposes of this
Agreement) by 50% of the current market price (determined pursuant to Section
11(d) hereof) per share of the Common Stock of such Principal Party on the date
of consummation of such Section 13 Event, provided, however, that the Purchase
Price (as theretofore adjusted in

                                       21
<PAGE>

accordance with Section 11(a)(ii) hereof) and the number of shares of Common
Stock of such Principal Party so receivable upon exercise of a Right shall be
subject to further adjustment as appropriate in accordance with Section 11(f)
hereof to reflect any events occurring in respect of the Common Stock of such
Principal Party after the occurrence of such Section 13 Event; (ii) such
Principal Party shall thereafter be liable for, and shall assume, by virtue of
such Section 13 Event, all the obligations and duties of the Company pursuant to
this Agreement; (iii) the term "Company" shall thereafter be deemed to refer to
such Principal Party in all respects; (iv) such Principal Party shall take such
steps (including, but not limited to, the reservation of a sufficient number of
shares of its Common Stock in accordance with Section 9 hereof) in connection
with the consummation of any such transaction as may be necessary to assure that
the provisions of this Agreement shall thereafter be applicable, as nearly as
reasonably may be, in relation to its shares of Common Stock thereafter
deliverable upon the exercise of the Rights, to its shares of Common Stock;
provided, however, that, upon the subsequent occurrence of any merger,
consolidation, sale of all or substantially all of the assets, recapitalization,
reclassification of shares, reorganization or other extraordinary transaction in
respect of such Principal Party, each holder of a Right shall thereupon be
entitled to receive, upon exercise of a Right and payment of the Purchase Price,
such cash, shares, rights, warrants and other property which such holder would
have been entitled to receive had it, at the time of such transaction, owned the
shares of Common Stock of the Principal Party purchasable upon the exercise of a
Right, and such Principal Party shall take such steps (including, but not
limited to, reservation of shares of stock) as may be necessary to permit the
subsequent exercise of the Rights in accordance with the terms hereof for such
cash, shares, rights, warrants and other property; and (v) the provisions of
Section 11(a)(ii) hereof shall be of no further effect following the first
occurrence of any Section 13 Event.

                  (b)  "Principal Party" shall mean:

                                    (i) in the case of any transaction described
                  in clause (x) or (y) of the first sentence of Section 13(a),
                  (A) the Person that is the issuer of any securities into which
                  shares of Company Common Stock are converted in such merger or
                  consolidation, or, if there is more than one such issuer, the
                  issuer of Common Stock that has the highest aggregate current
                  market price (determined pursuant to Section 11(d) hereof) and
                  (B) if no securities are so issued, the Person that is the
                  other party to such merger or consolidation, or, if there is
                  more than one such Person, the Person the Common Stock of
                  which has the highest aggregate current market price
                  (determined pursuant to Section 11(d) hereof); and

                                    (ii) in the case of any transaction
                  described in clause (z) of the first sentence of Section 13(a)
                  hereof, the Person that is the party receiving the largest
                  portion of the assets or earning power transferred pursuant to
                  such transaction or transactions, or, if each Person that is a
                  party to such transaction or transactions receives the same
                  portion of the assets or earning power transferred pursuant to
                  such transaction or transactions or if the Person receiving
                  the largest portion of the assets or earning power cannot be
                  determined, whichever Person the Common Stock of which has the
                  highest aggregate current market price (determined pursuant to
                  Section 11(d) hereof); provided, however, that in any such
                  case, (1) if

                                       22
<PAGE>

                  the Common Stock of such Person is not at such time and has
                  not been continuously over the preceding twelve-month period
                  registered under Section 12 of the Exchange Act ("Registered
                  Common Stock"), or such Person is not a corporation, and such
                  Person is a direct or indirect Subsidiary of another Person
                  that has Registered Common Stock outstanding, "Principal
                  Party" shall refer to such other Person; (2) if the Common
                  Stock of such Person is not Registered Common Stock or such
                  Person is not a corporation, and such Person is a direct or
                  indirect Subsidiary of another Person but is not a direct or
                  indirect Subsidiary of another Person which has Registered
                  Common Stock outstanding, "Principal Party" shall refer to the
                  ultimate parent entity of such first-mentioned Person; (3) if
                  the Common Stock of such Person is not Registered Common Stock
                  or such Person is not a corporation, and such Person is
                  directly or indirectly controlled by more than one Person, and
                  one or more of such other Persons has Registered Common Stock
                  outstanding, "Principal Party" shall refer to whichever of
                  such other Persons is the issuer of the Registered Common
                  Stock having the highest aggregate current market price
                  (determined pursuant to Section 11(d) hereof); and (4) if the
                  Common Stock of such Person is not Registered Common Stock or
                  such Person is not a corporation, and such Person is directly
                  or indirectly controlled by more than one Person, and none of
                  such other Persons have Registered Common Stock outstanding,
                  "Principal Party" shall refer to whichever ultimate parent
                  entity is the corporation having the greatest shareholders
                  equity or, if no such ultimate parent entity is a corporation,
                  shall refer to whichever ultimate parent entity is the entity
                  having the greatest net assets.

                  (c) The Company shall not consummate any such consolidation,
         merger, sale or transfer unless the Principal Party shall have a
         sufficient number of authorized shares of its Common Stock which have
         not been issued or reserved for issuance to permit the exercise in full
         of the Rights in accordance with this Section 13, and unless prior
         thereto the Company and such Principal Party shall have executed and
         delivered to the Rights Agent a supplemental agreement providing for
         the terms set forth in paragraphs (a) and (b) of this Section 13 and
         further providing that the Principal Party, at its own expense, shall:

                           (i) (A) file on an appropriate form, as soon as
                  practicable following the execution of such agreement, a
                  registration statement under the Securities Act with respect
                  to the Common Stock that may be acquired upon exercise of the
                  Rights, (B) cause such registration statement to remain
                  effective (and to include a prospectus complying with the
                  requirements of the Securities Act) until the Expiration Date,
                  and (C) as soon as practicable following the execution of such
                  agreement, take such action as may be required to assure that
                  any acquisition of such Common Stock upon the exercise of the
                  Rights complies with any applicable state securities or "blue
                  sky" laws; and

                           (ii) as soon as practicable following the execution
                  of such agreement, deliver to holders of the Rights historical
                  financial statements for the Principal

                                       23
<PAGE>

                  Party and each of its Affiliates which comply in all respects
                  with the requirements for registration on Form 10 under the
                  Exchange Act.

                  (d) In case the Principal Party which is to be a party to a
         transaction referred to in this Section 13 has a provision in any of
         its authorized securities or in its Certificate of Incorporation or
         By-laws or other instrument governing its corporate affairs, which
         provision would have the effect of (i) causing such Principal Party to
         issue, in connection with, or as a consequence of, the consummation of
         a transaction referred to in this Section 13, shares of Common Stock of
         such Principal Party at less than the then current market price per
         share (determined pursuant to Section 11(d) hereof) or securities
         exercisable for, or convertible into, Common Stock of such Principal
         Party at less than such then current market price (other than to
         holders of Rights pursuant to this Section 13) or (ii) providing for
         any special payment, tax or similar provisions in connection with the
         issuance of the Common Stock of such Principal Party pursuant to the
         provisions of this Section 13; then, in such event, the Company shall
         not consummate any such transaction unless prior thereto the Company
         and such Principal Party shall have executed and delivered to the
         Rights Agent a supplemental agreement providing that the provision in
         question of such Principal Party shall have been cancelled, waived or
         amended, or that the authorized securities shall be redeemed, so that
         the applicable provision will have no effect in connection with, or as
         a consequence of, the consummation of the proposed transaction.

                  (e) The provisions of this Section 13 shall similarly apply to
         successive mergers or consolidations or sales or other transfers. In
         the event that a Section 13 Event shall occur at any time after the
         occurrence of a Section 11(a)(ii) Event, the Rights which have not
         theretofore been exercised shall thereafter become exercisable, in the
         manner and for the securities described in Section 13(a).

         Section 14. Fractional Rights and Fractional Shares. (a) The Company
shall not be required to issue fractions of Rights or to distribute Rights
Certificates which evidence fractional Rights. In lieu of issuing such
fractional Rights, there shall be paid to the Persons to which such fractional
Rights would otherwise be issuable, an amount in cash equal to such fraction of
the market value of a whole Right. For purposes of this Section 14(a), the
market value of a whole Right shall be the closing price of the Rights for the
Trading Day immediately prior to the date on which such fractional Rights would
have been otherwise issuable. The closing price of the Rights for any day shall
be, if the Rights are listed or admitted to trading on a national securities
exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national securities exchange
on which the Rights are listed or admitted to trading or, if the Rights are not
listed or admitted to trading on any national securities exchange, the last
quoted price or, if not so quoted, the average of the high bid and low asked
prices in the over-the-counter market, as reported by Nasdaq or such other
system then in use or, if on any such date the Rights are not quoted by any such
organization, the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Rights selected by a majority
of the Board of Directors. If on any such date no such market maker is making a
market in the Rights, the fair value of the Rights on such date as determined in
good faith by a majority of the Board of Directors shall be used and such
determination shall be described in a statement filed with the Rights Agent and
the holders of the Rights.

                                       24
<PAGE>

                  (b) The Company shall not be required to issue fractions of
shares of Preferred Stock (other than fractions which are integral multiples of
one one-hundredth of a share of Preferred Stock) upon exercise of the Rights or
to distribute certificates which evidence such fractional shares of Preferred
Stock (other than fractions which are integral multiples of one one-hundredth of
a share of Preferred Stock); provided, however, that in lieu of fractions of
shares of Preferred Stock which are integral multiples of one one-hundredth of a
share of Preferred Stock, the Company may provide for the issuance of depositary
receipts pursuant to Section 7(c) hereof. In lieu of such fractional shares of
Preferred Stock that are not integral multiples of one one-hundredth of a share,
the Company may pay to the registered holders of Rights Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the then current market price of a share of Preferred Stock on the
day of exercise, determined in accordance with Section 11(d) hereof.

                  (c) The holder of a Right by the acceptance of the Rights
expressly waives his right to receive any fractional Rights or any fractional
shares upon exercise of a Right, except as permitted by this Section 14.

         Section 15. Rights of Action. All rights of action in respect of this
Agreement, other than rights of action vested in the Rights Agent pursuant to
Section 18 hereof, are vested in the respective registered holders of the Rights
Certificates (and, prior to the Distribution Date, the registered holders of
certificates representing shares of Company Common Stock); and any registered
holder of a Rights Certificate (or, prior to the Distribution Date, of a
certificate representing shares of Company Common Stock), without the consent of
the Rights Agent or of the holder of any other Rights Certificate (or, prior to
the Distribution Date, of a certificate representing shares of Company Common
Stock), may, in his own behalf and for his own benefit, enforce, and may
institute and maintain any suit, action or proceeding against the Company or any
other Person to enforce, or otherwise act in respect of, his right to exercise
the Rights evidenced by such Rights Certificate in the manner provided in such
Rights Certificate and in this Agreement. Without limiting the foregoing or any
remedies available to the holders of Rights, it is specifically acknowledged
that the holders of Rights would not have an adequate remedy at law for any
breach of this Agreement and shall be entitled to specific performance of the
obligations hereunder and injunctive relief against actual or threatened
violations of the obligations hereunder of any Person subject to this Agreement.

         Section 16. Agreement of Rights Holders. Every holder of a Right by
accepting the same consents and agrees with the Company and the Rights Agent and
with every other holder of a Right that:

                  (a) prior to the Distribution Date, the Rights will be
         transferable only in connection with the transfer of Company Common
         Stock;

                  (b) after the Distribution Date, the Rights Certificates are
         transferable only on the registry books of the Rights Agent if
         surrendered at the office of the Rights Agent designated for such
         purposes, duly endorsed or accompanied by a proper instrument of
         transfer and with the appropriate forms and certificates duly executed;

                                       25
<PAGE>

                  (c) subject to Section 6(a) and Section 7(f) hereof, the
         Company and the Rights Agent may deem and treat the person in whose
         name a Rights Certificate (or, prior to the Distribution Date, the
         associated Company Common Stock certificate) is registered as the
         absolute owner thereof and of the Rights evidenced thereby
         (notwithstanding any notations of ownership or writing on the Rights
         Certificates or the associated Company Common Stock certificate made by
         anyone other than the Company or the Rights Agent) for all purposes
         whatsoever, and neither the Company nor the Rights Agent, subject to
         the last sentence of Section 7 (e) hereof, shall be affected by any
         notice to the contrary; and

                  (d) notwithstanding anything in this Agreement to the
         contrary, neither the Company nor the Rights Agent shall have any
         liability to any holder of a Right or any other Person as a result of
         its inability to perform any of its obligations under this Agreement by
         reason of any preliminary or permanent injunction or other order,
         decree or ruling issued by a court of competent jurisdiction or by a
         governmental, regulatory or administrative agency or commission, or any
         statute, rule, regulation or executive order promulgated or enacted by
         any governmental authority, prohibiting or otherwise restraining
         performance of such obligation; provided, however, the Company must use
         its best efforts to have any such order, decree or ruling lifted or
         otherwise overturned as promptly as practicable.

         Section 17. Rights Certificate Holder Not Deemed a Stockholder. No
holder, as such, of any Rights Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the number of shares of
Preferred Stock or any other securities of the Company which may at any time be
issuable on the exercise of the Rights represented thereby, nor shall anything
contained herein or in any Rights Certificate be construed to confer upon the
holder of any Rights Certificate, as such, any of the rights of a stockholder of
the Company or any right to vote for the election of directors or upon any
matter submitted to stockholders at any meeting thereof, or to give or withhold
consent to any corporate action, or, except as provided in Section 24 hereof, to
receive notice of meetings or other actions affecting stockholders, or to
receive dividends or subscription rights, or otherwise, until the Right or
Rights evidenced by such Rights Certificate shall have been exercised in
accordance with the provisions hereof. This Section 17 shall also apply to
holders, as such, of Rights prior to the issuance of Rights Certificates.

         Section 18. Concerning the Rights Agent. (a) The Company agrees to pay
to the Rights Agent reasonable compensation for all services rendered by it
hereunder and, from time to time, on demand of the Rights Agent, its reasonable
expenses, including reasonable fees and disbursements of its counsel, incurred
in connection with the execution and administration of this Agreement and the
exercise and performance of its duties hereunder. The Company shall indemnify
the Rights Agent for, and hold it harmless against, any loss, liability, or
expense, incurred without negligence, bad faith or willful misconduct on the
part of the Rights Agent, for anything done or omitted by the Rights Agent in
connection with the acceptance and administration of this Agreement, including
the reasonable costs and expenses of defending against any claim of liability
hereunder.

                  (b) The Rights Agent shall be protected and shall incur no
liability for or in respect of any action taken, suffered or omitted by it in
connection with its administration of this

                                       26
<PAGE>

Agreement in reliance upon any Rights Certificate or certificate for Preferred
Stock or for other securities of the Company, instrument of assignment or
transfer, power of attorney, endorsement, affidavit, letter, notice, direction,
consent, certificate, statement or other paper or document believed by it to be
genuine and to have been signed, executed and, where necessary, verified or
acknowledged by the proper Person or Persons.

                  (c) The indemnity provided herein shall survive the expiration
of the Rights and the termination of this Agreement. In no case will the Rights
Agent be liable for special, indirect, incidental or consequential loss or
damage of any kind whatsoever (including but not limited to lost profits), even
if the Rights Agent has been advised of the possibility of such loss or damage.

         Section 19. Merger or Consolidation or Change of Name of Rights Agent.
(a) Any corporation into which the Rights Agent or any successor Rights Agent
may be merged or with which it may be consolidated, or any corporation resulting
from any merger or consolidation to which the Rights Agent or any successor
Rights Agent shall be a party, or any corporation succeeding to the corporate
trust or shareholder services businesses of the Rights Agent or any successor
Rights Agent, shall be the successor to the Rights Agent under this Agreement
without the execution or filing of any document or any further act on the part
of any of the parties hereto; provided, however, that such corporation would be
eligible for appointment as a successor Rights Agent under the provisions of
Section 21 hereof. In case at the time such successor Rights Agent shall succeed
to the agency created by this Agreement, any of the Rights Certificates shall
have been countersigned but not delivered, any such successor Rights Agent may
adopt the countersignature of a predecessor Rights Agent and deliver such Rights
Certificates so countersigned; and in case at that time any of the Rights
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Rights Certificates either in the name of the predecessor or in
the name of the successor Rights Agent; and in all such cases such Rights
Certificates shall have the full force provided in the Rights Certificates and
in this Agreement.

                  (b) In case at any time the name of the Rights Agent shall be
changed and at such time any of the Rights Certificates shall have been
countersigned but not delivered, the Rights Agent may adopt the countersignature
under its prior name and deliver Rights Certificates so countersigned; and in
case at that time any of the Rights Certificates shall not have been
countersigned, the Rights Agent may countersign such Rights Certificates either
in its prior name or in its changed name; and in all such cases such Rights
Certificates shall have the full force provided in the Rights Certificates and
in this Agreement.

         Section 20. Duties of Rights Agent. The Rights Agent undertakes the
duties and obligations imposed by this Agreement upon the following terms and
conditions, by all of which the Company and the holders of Rights Certificates,
by their acceptance thereof, shall be bound:

                  (a) The Rights Agent may consult with legal counsel (who may
         be legal counsel for the Company), and the opinion of such counsel
         shall be full and complete authorization and protection to the Rights
         Agent as to any action taken or omitted by it in good faith and in
         accordance with such opinion.

                                       27
<PAGE>

                  (b) Whenever in the performance of its duties under this
         Agreement the Rights Agent shall deem it necessary or desirable that
         any fact or matter (including, without limitation, the identity of any
         Acquiring Person and the determination of "current market price") be
         proved or established by the Company prior to taking or suffering any
         action hereunder, such fact or matter (unless other evidence in respect
         thereof be specified herein) may be deemed to be conclusively proved
         and established by a certificate signed by the Chairman of the Board,
         the Chief Executive Officer, the President, any Vice President, the
         Treasurer, any Assistant Treasurer, the Secretary or any Assistant
         Secretary of the Company and delivered to the Rights Agent; provided,
         however, that so long as any Person is an Acquiring Person hereunder,
         such certificate shall be signed and delivered by a majority of the
         Board of Directors; and such certificate shall be full authorization to
         the Rights Agent for any action taken or suffered in good faith by it
         under the provisions of this Agreement in reliance upon such
         certificate.

                  (c) The Rights Agent shall be liable hereunder only for its
         own negligence, bad faith or willful misconduct.

                  (d) The Rights Agent shall not be liable for or by reason of
         any of the statements of fact or recitals contained in this Agreement
         or in the Rights Certificates or be required to verify the same (except
         as to its countersignature on such Rights Certificates), but all such
         statements and recitals are and shall be deemed to have been made by
         the Company only.

                  (e) The Rights Agent shall not have any responsibility for the
         validity of this Agreement or the execution and delivery hereof (except
         the due execution hereof by the Rights Agent) or for the validity or
         execution of any Rights Certificate (except its countersignature
         thereof); nor shall it be responsible for any breach by the Company of
         any covenant or failure by the Company to satisfy conditions contained
         in this Agreement or in any Rights Certificate; nor shall it be
         responsible for any adjustment required under the provisions of Section
         11 or Section 13 hereof or for the manner, method or amount of any such
         adjustment or the ascertaining of the existence of facts that would
         require any such adjustment (except with respect to the exercise of
         Rights evidenced by Rights Certificates after receipt by the Rights
         Agent of the certificate describing any such adjustment contemplated by
         Section 12); nor shall it by any act hereunder be deemed to make any
         representation or warranty as to the authorization or reservation of
         any shares of Preferred Stock or any other securities to be issued
         pursuant to this Agreement or any Rights Certificate or as to whether
         any shares of Preferred Stock or any other securities will, when so
         issued, be validly authorized and issued, fully paid and
         non-assessable.

                  (f) The Company shall perform, execute, acknowledge and
         deliver or cause to be performed, executed, acknowledged and delivered
         all such further acts, instruments and assurances as may reasonably be
         required by the Rights Agent for the performance by the Rights Agent of
         its duties under this Agreement.

                  (g) The Rights Agent is hereby authorized and directed to
         accept instructions with respect to the performance of its duties
         hereunder from the Chairman of the Board, the

                                       28
<PAGE>

         Chief Executive Officer, the President, any Vice President, the
         Secretary, any Assistant Secretary, the Treasurer or any Assistant
         Treasurer of the Company, and to apply to such officers for advice or
         instructions in connection with its duties, and it shall not be liable
         for any action taken or suffered to be taken by it in good faith in
         accordance with instructions of any such officer; provided, however,
         that so long as any Person is an Acquiring Person hereunder, the Rights
         Agent shall accept such instructions and advice only from a majority of
         the Board of Directors and shall not be liable for any action taken or
         suffered to be taken by it in good faith in accordance with such
         instructions of the majority of the Board of Directors. Any application
         by the Rights Agent for written instructions from the Company may, at
         the option of the Rights Agent, set forth in writing any action
         proposed to be taken or omitted by the Rights Agent under this Rights
         Agreement and the date on and/or after which such action shall be taken
         or such omission shall be effective. The Rights Agent shall not be
         liable for any action taken by, or omission of, the Rights Agent in
         accordance with a proposal included in any such application on or after
         the date specified in such application (which date shall not be less
         than five Business Days after the date any such officer of the Company
         actually receives such application, unless any such officer shall have
         consented in writing to an earlier date) unless, prior to taking any
         such action (or the effective date in the case of an omission), the
         Rights Agent shall have received written instructions in response to
         such application specifying the action to be taken or omitted.

                  (h) The Rights Agent and any shareholder, director, officer or
         employee of the Rights Agent may buy, sell or deal in any of the Rights
         or other securities of the Company or have a pecuniary interest in any
         transaction in which the Company may be interested, or contract with or
         lend money to the Company or otherwise act as fully and freely as
         though it were not Rights Agent under this Agreement. Nothing herein
         shall preclude the Rights Agent from acting in any other capacity for
         the Company or for any other legal entity.

                  (i) The Rights Agent may execute and exercise any of the
         rights or powers hereby vested in it or perform any duty hereunder
         either itself or by or through its attorneys or agents.

                  (j) No provision of this Agreement shall require the Rights
         Agent to expend or risk its own funds or otherwise incur any financial
         liability in the performance of any of its duties or in the exercise of
         its rights hereunder if the Rights Agent shall have reasonable grounds
         for believing that repayment of such funds or adequate indemnification
         against such risk or liability is not reasonably assured to it.

                  (k) If, with respect to any Rights Certificate surrendered to
         the Rights Agent for exercise or transfer, the certificate attached to
         the form of assignment or form of election to purchase, as the case may
         be, has either not been completed, not signed or indicates an
         affirmative response to clause 1 and/or 2 thereof, the Rights Agent
         shall not take any further action with respect to such requested
         exercise or transfer without first consulting with the Company. If such
         certificate has been completed and signed and shows a negative response
         to clauses 1 and 2 of such certificate, unless previously instructed

                                       29
<PAGE>

         otherwise in writing by the Company (which instructions may impose on
         the Rights Agent additional ministerial responsibilities, but no
         discretionary responsibilities), the Rights Agent may assume without
         further inquiry that the Rights Certificate is not owned by a Person
         described in Section 7(e) hereof and shall not be charged with any
         knowledge to the contrary.

         Section 21. Change of Rights Agent. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement
upon thirty days' prior notice in writing mailed to the Company, and to each
transfer agent of the Preferred Stock and the Company Common Stock, by
registered or certified mail, and to the holders of the Rights Certificates by
first-class mail. The Company may remove the Rights Agent or any successor
Rights Agent upon thirty days' prior notice in writing, mailed to the Rights
Agent or successor Rights Agent, as the case may be, and to each transfer agent
of the Preferred Stock and the Company Common Stock, by registered or certified
mail, and to the holders of the Rights Certificates by first-class mail. If the
Rights Agent shall resign or be removed or shall otherwise become incapable of
acting, the Company shall appoint a successor to the Rights Agent. If the
Company shall fail to make such appointment within a period of thirty days after
giving notice of such removal or after it has been notified in writing of such
resignation or incapacity by the resigning or incapacitated Rights Agent or by
the holder of a Rights Certificate (who shall, with such notice, submit his
Rights Certificate for inspection by the Company), then any registered holder of
any Rights Certificate may apply to any court of competent jurisdiction for the
appointment of a new Rights Agent. Any successor Rights Agent, whether appointed
by the Company or by such a court, shall be (a) a corporation organized and
doing business under the laws of the United States or any state of the United
States in good standing, shall be authorized under applicable laws to exercise
corporate trust or stock transfer powers and shall be subject to supervision or
examination by federal or state authorities or (b) an Affiliate of a corporation
described in clause (a). After appointment, the successor Rights Agent shall be
vested with the same powers, rights, duties and responsibilities as if it had
been originally named as Rights Agent without further act or deed; but the
predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment, the Company shall file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of
the Preferred Stock and the Company Common Stock, and mail a notice thereof in
writing to the registered holders of the Rights Certificates. Failure to give
any notice provided for in this Section 21, however, or any defect therein,
shall not affect the legality or validity of the resignation or removal of the
Rights Agent or the appointment of the successor Rights Agent.

         Section 22. Issuance of New Rights Certificates. Notwithstanding any of
the provisions of this Agreement or the Rights to the contrary, the Company may,
at its option, issue new Rights Certificates evidencing Rights in such form as
may be approved by a majority of the Board of Directors to reflect any
adjustment or change made in accordance with the provisions of this Agreement in
the Purchase Price or the number or kind or class of shares or other securities
or property that may be acquired under the Rights Certificates. In addition, in
connection with the issuance or sale of shares of Company Common Stock following
the Distribution Date and prior to the Expiration Date, the Company (a) shall,
with respect to shares of Company Common Stock

                                       30
<PAGE>

so issued or sold pursuant to the exercise of stock options or under any
employee plan or arrangement, or upon the exercise, conversion or exchange of
securities hereinafter issued by the Company, and (b) may, in any other case, if
deemed necessary or appropriate by a majority of the Board of Directors, issue
Rights Certificates representing the appropriate number of Rights in connection
with such issuance or sale; provided, however, that (i) no such Rights
Certificate shall be issued if, and to the extent that, the Company shall be
advised by counsel that such issuance would create a significant risk of
material adverse tax consequences to the Company or the Person to whom such
Rights Certificate would be issued, and (ii) no such Rights Certificate shall be
issued if, and to the extent that, appropriate adjustment shall otherwise have
been made in lieu of the issuance thereof.

         Section 23. Redemption and Termination. (a) Subject to Section 30
hereof, the Company may, at its option, by action of a majority of the Board of
Directors, at any time prior to the earlier of (i) the Close of Business on the
tenth Business Day following the Stock Acquisition Date or (ii) the Final
Expiration Date, redeem all but not less than all of the then outstanding Rights
at a redemption price of $.01 per Right, as such amount may be appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof (such redemption price being the "Redemption
Price"). The Company may, at its option, by action of a majority of the Board of
Directors, pay the Redemption Price either in shares of Company Common Stock
(based on the "current market price", as defined in Section 11(d) hereof, of the
shares of Company Common Stock at the time of redemption) or cash and the
redemption of the Rights shall be effective on the basis and with such
conditions as the Board of Directors may in its sole discretion establish.

                  (b) Immediately upon the action of a majority of the Board of
Directors ordering the redemption of the Rights, evidence of which shall be
filed with the Rights Agent, and without any further action and without any
notice, the right to exercise the Rights will terminate and the only right
thereafter of the holders of Rights shall be to receive the Redemption Price for
each Right so held. The Company shall promptly give public notice of any such
redemption; provided, however, that the failure to give, or any defect in, any
such notice shall not affect the validity of such redemption. Promptly after the
action of a majority of the Board of Directors ordering the redemption of the
Rights, the Company shall give notice of such redemption to the Rights Agent and
the holders of the then outstanding Rights by mailing such notice to all such
holders at each holder's last address as it appears upon the registry books of
the Rights Agent or, prior to the Distribution Date, on the registry books of
the transfer agent for the Company Common Stock. Any notice which is mailed in
the manner herein provided shall be deemed given, whether or not the holder
receives the notice. Each such notice of redemption will state the method by
which the payment of the Redemption Price will be made.

         Section 24. Notice of Certain Events. (a) In case the Company shall
propose, at any time after the Distribution Date, (i) to pay any dividend
payable in stock of any class to the holders of Preferred Stock or to make any
other distribution to the holders of Preferred Stock (other than a regular
quarterly cash dividend paid out of funds legally available therefor), (ii) to
offer to the holders of Preferred Stock rights or warrants to subscribe for or
to purchase any additional shares of Preferred Stock or shares of stock of any
class or any other securities, rights or options, (iii) to effect any
reclassification of its Preferred Stock (other than a reclassification involving
only the

                                       31
<PAGE>

subdivision of outstanding shares of Preferred Stock), (iv) to effect any
consolidation or merger into or with any other Person, or to effect any sale or
other transfer (or to permit one or more of its Subsidiaries to effect any sale
or other transfer), in one or more transactions, of more than 50% of the assets
or earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person or Persons (other than a transfer by the Company and/or any of its
wholly owned Subsidiaries in one or more transactions each of which complies
with Section 11(o) hereof), or (v) to effect the liquidation, dissolution or
winding up of the Company, then, in each such case, the Company shall give to
each holder of a Rights Certificate, to the extent feasible and in accordance
with Section 25 hereof, a notice of such proposed action, which shall specify
the record date for the purposes of such stock dividend, distribution of rights
or warrants, or the date on which such reclassification, consolidation, merger,
sale, transfer, liquidation, dissolution, or winding up is to take place and the
date of participation therein by the holders of the shares of Preferred Stock,
if any such date is to be fixed, and such notice shall be so given in the case
of any action covered by clause (i) or (ii) above at least twenty (20) days
prior to the record date for determining holders of the shares of Preferred
Stock for purposes of such action, and in the case of any such other action, at
least twenty (20) days prior to the date of the taking of such proposed action
or the date of participation therein by the holders of the shares of Preferred
Stock whichever shall be the earlier; provided, however, no such notice shall be
required pursuant to this Section 24, if any wholly owned Subsidiary of the
Company effects a consolidation or merger with or into, or effects a sale or
other transfer of assets or earnings power to, any other wholly owned Subsidiary
of the Company.

                  (b) In case any Triggering Event shall occur, then, in any
such case, (i) the Company shall as soon as practicable thereafter give to each
holder of a Rights Certificate, to the extent feasible and in accordance with
Section 25 hereof, a notice of the occurrence of such event, which shall specify
the event and the consequences of the event to holders of Rights under Section
11(a)(ii) or Section 13 hereof, as the case may be.

         Section 25. Notices. All notices and other communications provided for
hereunder shall, unless otherwise stated herein, be in writing (including by
telex, telegram or cable) and mailed or sent or delivered, if to the Company, at
its address at:

         Atrix Laboratories, Inc.
         2579 Midpoint Drive
         Fort Collins, Colorado 80525
         Attention: President

         and if to the Rights Agent, at its address at:

         American Stock Transfer & Trust Company
         6201 15th Avenue, Floor 3L
         Brooklyn, NY  11219
         Attention:  Relationship Manager

                                       32
<PAGE>

         Notices or demands authorized by this Agreement to be given or made by
the Company or the Rights Agent to the holder of any Rights Certificate (or, if
prior to the Distribution Date, to the holder of certificates representing
shares of Company Common Stock) shall be sufficiently given or made if sent by
first-class mail, postage prepaid, addressed to such holder at the address of
such holder as shown on the registry books of the Company.

         Section 26. Supplements and Amendments. Prior to the Distribution Date
and subject to the penultimate sentence of this Section 26, the Company may, in
its sole and absolute discretion, and the Rights Agent shall, if the Company so
directs, supplement or amend any provision of this Agreement in any respect
without the approval of any holders of certificates representing shares of
Company Common Stock. From and after the Distribution Date and subject to the
penultimate sentence of this Section 26, the Company and the Rights Agent shall,
if the Company so directs, supplement or amend this Agreement without the
approval of any holders of Rights Certificates in order (i) to cure any
ambiguity, (ii) to correct or supplement any provision contained herein which
may be defective or inconsistent with any other provisions herein, (iii) to
shorten or lengthen any time period hereunder, or (iv) to change or supplement
the provisions hereunder in any manner which the Company may deem necessary or
desirable and which shall not adversely affect the interests of the holders of
Rights Certificates (other than an Acquiring Person or an Affiliate or Associate
of an Acquiring Person); provided, however, that this Agreement may not be
supplemented or amended to lengthen, pursuant to clause (iii) of this sentence,
(A) subject to Section 30 hereof, a time period relating to when the Rights may
be redeemed at such time as the Rights are not then redeemable, or (B) any other
time period unless such lengthening is for the purpose of protecting, enhancing
or clarifying the rights of, and/or the benefits to, the holders of Rights.
Without limiting the foregoing, the Company may at any time prior to such time
as any Person becomes an Acquiring Person amend this Agreement to lower the
thresholds set forth in Section 1(a) to not less than the greater of (i) the sum
of .001% and the largest percentage of the outstanding shares of Company Common
Stock then known by the Company to be beneficially owned by any Person (other
than the Company, any Subsidiary of the Company, any employee benefit plan of
the Company or any Subsidiary of the Company, or any entity holding Company
Common Stock for or pursuant to the terms of any such plan), and (ii) 10%. Upon
the delivery of a certificate from an appropriate officer of the Company or, so
long as any Person is an Acquiring Person hereunder, from the majority of the
Board of Directors, which states that the proposed supplement or amendment is in
compliance with the terms of this Section 26, the Rights Agent shall execute
such supplement or amendment. Notwithstanding anything contained in this
Agreement to the contrary, (i) no supplement or amendment shall be made which
changes the Redemption Price, the Purchase Price, the Expiration Date or the
number of Units of Preferred Stock or other securities or assets for which a
Right is exercisable without the approval of a majority of the Board of
Directors, and (ii) following the occurrence of a Section 11(a)(ii) Event, no
supplement or amendment whatsoever shall be made without the approval of the
Board of Directors. Prior to the Distribution Date, the interests of the holders
of Rights shall be deemed coincident with the interests of the holders of
Company Common Stock.

         Section 27. Successors. All the covenants and provisions of this
Agreement by or for the benefit of the Company or the Rights Agent shall bind
and inure to the benefit of their respective successors and assigns hereunder.

                                       33

         Section 28. Determinations and Actions by the Board of Directors, etc.
For all purposes of this Agreement, any calculation of the number of shares of
Company Common Stock outstanding at any particular time, including for purposes
of determining the particular percentage of such outstanding shares of Company
Common Stock of which any Person is the Beneficial Owner, shall be made in
accordance with the last sentence of Rule 13d-3(d)(1)(i) of the Exchange Act
Regulations as in effect on the date hereof. Except as otherwise specifically
provided herein, the Board of Directors of the Company shall have the exclusive
power and authority to administer this Agreement and to exercise all rights and
powers specifically granted to the Board of Directors or to the Company, or as
may be necessary or advisable in the administration of this Agreement,
including, without limitation, the right and power (i) to interpret the
provisions of this Agreement, and (ii) to make all determinations deemed
necessary or advisable for the administration of this Agreement. All such
actions, calculations, interpretations and determinations which are done or made
by the Board of Directors in good faith shall (x) be final, conclusive and
binding on the Company, the Rights Agent, the holders of the Rights and all
other parties, and (y) not subject the Board of Directors or any member thereof
to any liability to the holders of the Rights.

         Section 29. Benefits of this Agreement. Nothing in this Agreement shall
be construed to give to any Person other than the Company, the Rights Agent and
the registered holders of the Rights Certificates (and, prior to the
Distribution Date, registered holders of shares of Company Common Stock) any
legal or equitable right, remedy or claim under this Agreement; but this
Agreement shall be for the sole and exclusive benefit of the Company, the Rights
Agent and the registered holders of the Rights Certificates (and, prior to the
Distribution Date, registered holders of shares of Company Common Stock).

         Section 30. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated;
provided, however, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and a majority of the
Board of Directors determines in its good faith judgment that severing the
invalid language from this Agreement would adversely affect the purpose or
effect of this Agreement and the Rights shall not then be redeemable, the right
of redemption set forth in Section 23 hereof shall be reinstated and shall not
expire until the Close of Business on the tenth Business Day following the date
of such determination by a majority of the Board of Directors.

         Section 31. Governing Law. This Agreement, each Right and each Rights
Certificate issued hereunder shall be governed by, and construed in accordance
with, the laws of the State of Delaware applicable to contracts executed in and
to be performed entirely in such State.

         Section 32. Counterparts. This Agreement may be executed (including by
facsimile) in one or more counterparts, and by the different parties hereto in
separate counterparts, each of which when executed shall be deemed to be an
original, but all of which taken together shall constitute one and the same
instrument.

         Section 33. Descriptive Headings. The headings contained in this
Agreement are for descriptive purposes only and shall not affect in any way the
meaning or interpretation of this Agreement.

         Section 34. Exchange. (a) The Company, upon resolution of a majority of
the Board of Directors may, at its option, at any time after the first
occurrence of a Section 11(a)(ii) Event, exchange all or part of the then
outstanding and exercisable Rights (which shall not include Rights that have
become void pursuant to Section 7(e) hereof) for Units of Preferred Stock or
shares of Company Common Stock (at the election of the Board of Directors) at an
exchange ratio of one Unit of Preferred Stock or one share of Company Common
Stock, as the case may be, per Right, as appropriately adjusted to reflect any
stock split, stock dividend or similar transaction occurring after the date
hereof (such exchange ratio being the "Exchange Ratio"). Notwithstanding the
foregoing, the Board of Directors shall not be empowered to effect such exchange
at any time after any Person (other than an Exempt Person), together with all
Affiliates and Associates of such Person, becomes the Beneficial Owner of shares
of Company Common Stock aggregating 50% or more of the shares of Company Common
Stock then outstanding. From and after the occurrence of a Section 13(a) Event,
any Rights that theretofore have not been exchanged pursuant to this Section
34(a) shall thereafter be exercisable only in accordance with Section 13 and may
not be exchanged pursuant to this Section 34(a). The exchange of the Rights by
the Board of Directors may be made effective at such time, on such basis and
with such conditions as the Board of Directors in its sole discretion may
establish.

                  (b) Immediately upon the action of a majority of the Board of
Directors ordering the exchange of any Rights pursuant to Section 34(a) and
without any further action and without any notice, the right to exercise such
Rights shall terminate and the only right thereafter of a holder of such Rights
shall be to receive that number of Units of Preferred Stock or shares of Company
Common Stock, as the case may be, equal to the number of such Rights held by
such holder multiplied by the Exchange Ratio. The Company shall promptly give
public notice of any such exchange; provided, however, that the failure to give,
or any defect in, such notice shall not affect the validity of such exchange.
The Company promptly shall mail a notice of any such exchange to all of the
holders of such Rights at their last addresses as they appear upon the registry
books of the Rights Agent. Any notice which is mailed in the manner herein
provided shall be deemed given, whether or not the holder receives the notice.
Each such notice of exchange shall state the method by which the exchange of
Units of Preferred Stock or shares of Company Common Stock, as the case may be,
for Rights will be effected and, in the event of any partial exchange, the
number of Rights which will be exchanged. Any partial exchange shall be effected
pro rata based on the number of Rights (other than Rights which have become void
pursuant to the provisions of Section 7(e) hereof) held by each holder of
Rights.

                  (c) In the event that the number of shares of Preferred Stock
or Company Common Stock, as the case may be, which are authorized by the
Company's Amended and Restated Certificate of Incorporation but not outstanding
or reserved for issuance for purposes other than upon exercise of the Rights are
not sufficient to permit any exchange of Rights as contemplated in accordance
with this Section 34, the Company, upon a resolution of a majority of the Board
of Directors, shall take all such action as may be necessary to authorize
additional shares of Preferred Stock or Company Common Stock, as the case may
be, for issuance upon exchange of

                                       35

the Rights or make adequate provision to substitute, in whole or in part, (1)
cash, (2) other equity securities of the Company, (3) debt securities of the
Company, (4) other assets, or (5) any combination of the foregoing, having an
aggregate value for each Right to be exchanged equal to the per share market
price of one Unit of Preferred Stock or share of Company Common Stock, as the
case may be (determined pursuant to Section 11(d) hereof) as of the date of a
Section 11(a)(ii) Event, where such aggregate value has been determined by a
majority of the Board of Directors.

                  (d) The Company shall not be required to issue fractions of
Units of Preferred Stock or fractions of shares of Company Common Stock or to
distribute certificates which evidence fractional Units or fractional shares. In
lieu of issuing fractional Units or fractional shares, the Company may pay to
the registered holders of Rights Certificates at the time such Rights are
exchanged as herein provided an amount in cash equal to the same fraction of the
current market price (determined pursuant to Section 11(d) hereof) of one Unit
of Preferred Stock or one share of Company Common Stock, as the case may be, on
the Trading Day immediately prior to the date of exchange pursuant to this
Section 34.

NOT EXERCISABLE AFTER THE EXPIRATION DATE (AS DEFINED IN THE RIGHTS AGREEMENT
REFERRED TO BELOW). THE RIGHTS ARE SUBJECT TO REDEMPTION OR EXCHANGE, AT THE
OPTION OF THE COMPANY, ON THE TERMS SET FORTH IN THE RIGHTS AGREEMENT. UNDER

                               Rights Certificate

                            ATRIX LABORATORIES, INC.

         This certifies that ______________________, or registered assigns, is
the registered holder of the number of Rights set forth above, each of which
entitles the registered holder thereof, subject to the terms and conditions of
the Amended and Restated Rights Agreement dated as of November 16, 2001, as
amended from time to time (the "Rights Agreement"; terms defined therein are
used herein with the same meaning unless otherwise defined herein) between Atrix
Laboratories, Inc., a Delaware corporation (the "Company"), and American Stock
Transfer & Trust Company, a New York corporation, as Rights Agent (which term
shall include any successor Rights Agent under the Rights Agreement), to
purchase from the Company at any time after the Distribution Date and prior to
the Expiration Date at the office of the Rights Agent, one one-hundredth of a
fully paid and nonassessable share of Series A Preferred Stock, par value $.001
per share (the "Preferred Stock"), of the Company at the Purchase Price
initially of $67.50 per one one-hundredth share of Preferred Stock (each such
one one-hundredth of a share being a "Unit"), upon presentation and surrender of
this Rights Certificate with the Election to Purchase and related certificate
duly executed. The number of Rights evidenced by this Rights Certificate (and
the number of shares which may be purchased upon exercise thereof) set forth
above, and the Purchase Price per Unit set forth above, and the Purchase Price
per share set forth above, are the number and Purchase Price as of September 25,
1998 based on the Preferred Stock as constituted at such date. The Company
reserves the right to require prior to the occurrence of a Triggering Event (as
such term is defined in the Rights Agreement) that a number of Rights be
exercised so that only whole shares of Preferred Stock will be issued.

         UPON THE OCCURRENCE OF A SECTION 11(a)(ii) EVENT, IF THE RIGHTS
EVIDENCED BY THIS RIGHTS CERTIFICATE ARE BENEFICIALLY OWNED BY AN ACQUIRING
PERSON OR AN AFFILIATE OR ASSOCIATE OF ANY SUCH ACQUIRING PERSON OR, UNDER
CERTAIN CIRCUMSTANCES DESCRIBED IN THE RIGHTS AGREEMENT, A TRANSFEREE OF ANY
SUCH ACQUIRING PERSON,

                                      A-1
<PAGE>

ASSOCIATE OR AFFILIATE, SUCH RIGHTS SHALL BECOME NULL AND VOID AND NO HOLDER
HEREOF SHALL HAVE ANY RIGHT WITH RESPECT TO SUCH RIGHTS FROM AND AFTER THE
OCCURRENCE OF SUCH SECTION 11(a)(ii) EVENT.

         In certain circumstances described in the Rights Agreement, the Rights
evidenced hereby may entitle the registered holder thereof to purchase capital
stock of an entity other than the Company or receive common stock, cash or other
assets, all as provided in the Rights Agreement.

         As provided in the Rights Agreement, the Purchase Price and the number
and kind of shares of Preferred Stock or other securities, which may be
purchased upon the exercise of the Rights evidenced by this Rights Certificate
are subject to modification and adjustment upon the happening of certain events,
including a Triggering Event.

         This Rights Certificate is subject to all of the terms and conditions
of the Rights Agreement, which terms and conditions are hereby incorporated
herein by reference and made a part hereof and to which Rights Agreement
reference is hereby made for a full description of the rights, limitations of
rights, obligations, duties and immunities hereunder of the Rights Agent, the
Company and the holders of the Rights Certificates, which limitations of rights
include the temporary suspension of the exercisability of such Rights under the
specific circumstances set forth in the Rights Agreement. Copies of the Rights
Agreement are on file at the principal office of the Rights Agent and are
available from the Rights Agent upon written request.

         This Rights Certificate, with or without other Rights Certificates,
upon surrender at the office of the Rights Agent designated for such purpose,
may be exchanged for another Rights Certificate or Rights Certificates of like
tenor and date evidencing an aggregate number of Rights equal to the aggregate
number of Rights evidenced by the Rights Certificate or Rights Certificates
surrendered. If this Rights Certificate shall be exercised in part, the
registered holder shall be entitled to receive, upon surrender hereof, another
Rights Certificate or Rights Certificates for the number of whole Rights not
exercised.

         Subject to the provisions of the Rights Agreement, the Rights evidenced
by this Certificate may be redeemed by the Company under certain circumstances
at its option at a redemption price of $.01 per Right, at any time prior to the
earlier of the close of business on (i) the tenth business day following the
Stock Acquisition Date (as such time period may be extended pursuant to the
Rights Agreement), and (ii) the Final Expiration Date. In addition, the Rights
may be exchanged, in whole or in part, for shares of the Company Common Stock or
Units of Preferred Stock. Immediately upon the action of the Board of Directors
of the Company authorizing any such exchange, and without any further action or
any notice, the Rights (other than Rights which are not subject to such
exchange) will terminate and the Rights will only enable holders to receive the
shares issuable upon such exchange.

                                      A-2
<PAGE>

         No fractional shares of Preferred Stock will be issued upon the
exercise of any Right or Rights evidenced hereby (other than fractions which are
integral multiples of one one-hundredth of a share of Preferred Stock or
depositary receipts representing such fractions), but in lieu thereof a cash
payment will be made, as provided in the Rights Agreement.

         No holder of this Rights Certificate, as such, shall be entitled to
vote or receive dividends or be deemed for any purpose the holder of Preferred
Stock or of any other securities which may at any time be issuable on the
exercise hereof, nor shall anything contained in the Rights Agreement or herein
be construed to confer upon the holder hereof, as such, any of the rights of a
stockholder of the Company or any right to vote for the election of directors or
upon any matter submitted to stockholders at any meeting thereof, or to give or
withhold consent to any corporate action, or to receive notice of meetings or
other actions affecting stockholders (except as provided in the Rights
Agreement), or to receive dividends of subscription rights, or otherwise, until
the Rights evidenced by this Rights Certificate shall have been exercised as
provided in the Rights Agreement.

         This Rights Certificate shall not be valid or obligatory for any
purpose until it shall have been countersigned by the Rights Agent.

         WITNESS the facsimile signature of the proper officers of the Company.

                           UNDER CERTAIN CIRCUMSTANCES
                      (SPECIFIED IN THE RIGHTS AGREEMENT),
                 RIGHTS BENEFICIALLY OWNED BY ACQUIRING PERSONS
                      (AS DEFINED IN THE RIGHTS AGREEMENT)
                     OR ANY SUBSEQUENT HOLDER OF SUCH RIGHTS
                            MAY BECOME NULL AND VOID.

                  SUMMARY OF RIGHTS TO PURCHASE PREFERRED STOCK

         On September 25, 1998 the Board of Directors of Atrix Laboratories,
Inc. (the "Company") authorized and declared a dividend distribution of one
Right for each outstanding share of its Common Stock, par value $.001 per share
(the "Company Common Stock"), to stockholders of record at the close of business
on September 25, 1998 (the "Record Date"), and authorized the issuance of one
Right with each share of Company Common Stock issued (including shares
distributed from Treasury) by the Company thereafter between the Record Date and
the Distribution Date (as defined below). Each Right entitles the registered
holder, subject to the terms of the Rights Agreement (as defined below), to
purchase from the Company one one-hundredth of a share (a "Unit") of Series A
Preferred Stock, par value $.001 per share (the "Preferred Stock"), at a
purchase price of $67.50 per Unit, subject to adjustment. The purchase price is
payable in cash or by certified or bank check or money order payable to the
order of the Company. The description and terms of the Rights are set forth in
the Amended and Restated Rights Agreement between the Company and American Stock
Transfer & Trust Company, as Rights Agent, dated as of November 16, 2001, as
amended from time to time (the "Rights Agreement").

         Copies of the Rights Agreement, including the Certificate of
Designation for the Preferred Stock, has been filed by the Company with the
Securities and Exchange Commission as an exhibit to the Company's Current Report
on Form 8-K dated November 16, 2001. Copies of the Rights Agreement and the
Certificate of Designation are available free of charge from the Company. This
summary description of the Rights and the Preferred Stock does not purport to be
complete and is qualified in its entirety by reference to all of the provisions
of the Rights Agreement and the Certificate of Designation, including the
definitions therein of certain terms, which Rights Agreement and Certificate of
Designation are incorporated herein by reference.

         The Rights Agreement

         Initially, the Rights will attach to all certificates representing
shares of outstanding Company Common Stock, and no separate Rights Certificates
will be distributed. The Rights will separate from the Company Common Stock and
the "Distribution Date" will occur upon the earlier of (i) ten business days
following a public announcement (the date of such announcement being the "Stock
Acquisition Date") that a person or group of affiliated or associated persons
has acquired or otherwise obtained beneficial ownership of 15% or more of the
then outstanding

                                      B-1
<PAGE>

shares of Company Common Stock (an "Acquiring Person"), and (ii) ten business
days (or such later date as may be determined by action of the Board of
Directors prior to such time as any person becomes an Acquiring Person)
following the commencement of a tender offer or exchange offer that would result
in a person or group beneficially owning 15% or more of the then outstanding
shares of Company Common Stock. Until the Distribution Date, (i) the Rights will
be evidenced by Company Common Stock certificates and will be transferred with
and only with such Company Common Stock certificates, (ii) new Company Common
Stock certificates issued after the Record Date (also including shares
distributed from Treasury) will contain a notation incorporating the Rights
Agreement by reference, and (iii) the surrender for transfer of any certificates
representing outstanding Company Common Stock will also constitute the transfer
of the Rights associated with the Company Common Stock represented by such
certificates.

         An "Acquiring Person" does not include (A) the Company; (B) any
Subsidiary of the Company; (C) any employee benefit plan maintained by the
Company or any of its Subsidiaries; (D) any trustee or fiduciary with respect to
such employee benefit plan acting in such capacity or a trustee or fiduciary
holding shares of Company Common Stock for the purpose of funding any such plan
or employee benefits; (E) any Person if the Board of Directors of the Company
determines in good faith that such Person who would otherwise be an "Acquiring
Person" became such inadvertently (including, without limitation, because (x)
such Person was unaware that it beneficially owned a percentage of Company
Common Stock that would otherwise cause such Person to be an "Acquiring Person"
or (y) such Person was aware of the extent of its Beneficial Ownership of
Company Common Stock but had no actual knowledge of the consequences of such
Beneficial Ownership under this Agreement) and without any intention of changing
or influencing control of the Company, and if such Person does not acquire any
additional shares of Company Common Stock and as promptly as practicable
divested or divests itself of Beneficial Ownership of a sufficient number of
shares of Company Common Stock so that such Person would no longer be an
"Acquiring Person;" or (F) any Person who becomes the Beneficial Owner of 15% or
more of the then outstanding shares of Company Common Stock as a result of the
acquisition of shares of Company Common Stock directly from the Company in one
or more transactions approved by a majority of the Board of Directors, and (ii)
no Person shall be deemed an "Acquiring Person" as a result of the acquisition
of shares of Company Common Stock by the Company which, by reducing the number
of shares of Company Common Stock outstanding, increases the proportional number
of shares beneficially owned by such Person; provided, however, that if (A) a
Person would become an Acquiring Person (but for the operation of this subclause
(ii)) as a result of the acquisition of shares of Company Common Stock by the
Company and (B) after such share acquisition by the Company, such Person becomes
the Beneficial Owner of any additional shares of Company Common Stock, then such
Person shall be deemed an Acquiring Person unless upon becoming the Beneficial
Owner of such additional shares such Person is the Beneficial Owner of less than
15% of the then outstanding shares of Company Common Stock.

         The Rights are not exercisable until the Distribution Date and will
expire at the close of business on the tenth anniversary of the Rights Agreement
unless earlier redeemed or exchanged by the Company as described below. Under
certain circumstances the exercisability of the Rights

                                      B-2
<PAGE>

may be suspended. In no event, however, will the Rights be exercisable prior to
the expiration of the period in which the Rights may be redeemed.

         As soon as practicable after the Distribution Date, Rights Certificates
will be mailed to holders of record of Company Common Stock as of the close of
business on the Distribution Date and, thereafter, the separate Rights
Certificates alone will represent the Rights.

         In the event that a person becomes an Acquiring Person, then, in such
case, each holder of a Right will thereafter have the right to receive, upon
exercise, shares of Company Common Stock (or, in certain circumstances, cash,
property or other securities of the Company) having a value equal to two times
the exercise price of the Right. The exercise price is the purchase price
multiplied by the number of Units of Preferred Stock issuable upon exercise of a
Right prior to the event described in this paragraph. Notwithstanding any of the
foregoing, following the occurrence of the event set forth in this paragraph,
all Rights that are, or (under certain circumstances specified in the Rights
Agreement) were, beneficially owned by any Acquiring Person will be null and
void.

         In the event that, at any time following the date that any person
becomes an Acquiring Person, (i) the Company is acquired in a merger or other
business combination transaction and the Company is not the surviving
corporation, (ii) any person merges with the Company and all or part of the
Company Common Stock is converted or exchanged for securities, cash or property
of the Company or any other person or (iii) 50% or more of the Company's assets
or earning power is sold or transferred, each holder of a Right (except Rights
which previously have been voided as described above) shall thereafter have the
right to receive, upon exercise, common stock of the Acquiring Person having a
value equal to two times the exercise price of the Right.

         The purchase price payable, and the number of Units of Preferred Stock
issuable, upon exercise of the Rights are subject to adjustment from time to
time to prevent dilution (i) in the event of a stock dividend on, or a
subdivision, combination or reclassification of, the Preferred Stock, (ii) if
holders of the Preferred Stock are granted certain rights or warrants to
subscribe for Preferred Stock or convertible securities at less than the current
market price of the Preferred Stock, or (iii) upon the distribution to the
holders of the Preferred Stock of evidences of indebtedness, cash or assets
(excluding regular quarterly cash dividends) or of subscription rights or
warrants (other than those referred to above).

         With certain exceptions, no adjustment in the purchase price will be
required until cumulative adjustments amount to at least 1% of the purchase
price. The Company is not required to issue fractional shares of Preferred Stock
(other than fractions which are integral multiples of one one-hundredth of a
share of Preferred Stock which may be evidenced by depositary receipts). In lieu
thereof, an adjustment in cash may be made based on the current market price of
a share of Preferred Stock on the day of exercise.

         At any time until ten business days following the Stock Acquisition
Date, a majority of the Board of Directors may redeem the Rights in whole, but
not in part, at a price of $.01 per Right (subject to adjustment in certain
events) (the "Redemption Price") payable, at the election of the majority of the
Board of Directors, in cash or shares of Company Common Stock.

                                      B-3
<PAGE>

Immediately upon the action of a majority of the Board of Directors ordering the
redemption of the Rights, the Rights will terminate and the only right of the
holders of Rights will be to receive the Redemption Price.

         The Company may at any time after there is an Acquiring Person, by
action of a majority of the Board of Directors, exchange all or part of the then
outstanding and exercisable Rights (other than Rights that shall have become
null and void) for shares of Company Common Stock pursuant to a one-for-one
exchange ratio, as adjusted.

         Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends. While the distribution of the Rights will not
be taxable to stockholders or to the Company, stockholders may, depending upon
the circumstances, recognize taxable income in the event that the Rights become
exercisable for Units of Preferred Stock (or other consideration).

         Any of the provisions of the Rights Agreement may be amended without
the approval of the holders of Company Common Stock at any time prior to the
Distribution Date, including an amendment to lower certain thresholds described
above to not less than the greater of (i) the sum of .001% and the largest
percentage of the outstanding shares of Company Common Stock then known to the
Company to be beneficially owned by any person or group of affiliated or
associated persons, and (ii) 10%. After the Distribution Date, the provisions of
the Rights Agreement may be amended in order to cure any ambiguity, defect or
inconsistency, to make changes which do not adversely affect the interests of
holders of Rights (excluding the interests of any Acquiring Person), or to
shorten or lengthen any time period under the Rights Agreement; provided,
however, that no amendment to adjust (i) the time period governing redemption
shall be made at such time as the Rights are not redeemable or (ii) any other
time period unless such lengthening is for the purpose of protecting, enhancing
or clarifying the Rights of and/or benefiting, the holders of Rights. In
addition, after a person becomes an Acquiring Person, no amendment or supplement
may be made without the approval of a majority of the Board of Directors.

         Description of Preferred Stock

         The Units of Preferred Stock that may be acquired upon exercise of the
Rights will be nonredeemable and subordinate to any other shares of preferred
stock that may be issued by the Company.

         Each Unit of Preferred Stock will have a minimum preferential quarterly
dividend of $.01 per Unit or any higher per share dividend declared on the
Company Common Stock.

         In the event of liquidation, the holder of a Unit of Preferred Stock
will receive a preferred liquidation payment equal to the greater of $.01 per
Unit and the per share amount paid in respect of a share of the Company Common
Stock.

         Each Unit of Preferred Stock will have one vote, voting together with
the Company Common Stock.

                                      B-4
<PAGE>

         In the event of any merger, consolidation or other transaction in which
shares of Company Common Stock are exchanged, each Unit of Preferred Stock will
be entitled to receive the per share amount paid in respect of each share of
Company Common Stock.

         The rights of holders of the Preferred Stock with respect to dividends,
liquidation and voting, and in the event of mergers and consolidations, are
protected by customary antidilution provisions.

         Because of the nature of the Preferred Stock's dividend, liquidation
and voting rights, the economic value of one Unit of Preferred Stock that may be
acquired upon the exercise of each Right should approximate the economic value
of one share of Company Common Stock.

                           CERTIFICATE OF DESIGNATION
                                     OF THE
                            SERIES A PREFERRED STOCK

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

 Pursuant to Section 151 of the General Corporation Law of the State of Delaware

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

         The undersigned officers of Atrix Laboratories, Inc., a corporation
organized and existing under the General Corporation Law of the State of
Delaware (the "Corporation"), in accordance with the provisions of Section 103
thereof, DO HEREBY CERTIFY:

         That, pursuant to the authority conferred upon the Board of Directors
of the Corporation by its Amended and Restated Certificate of Incorporation (the
"Certificate"), the said Board of Directors, at a duly called meeting held on
August 2, 1998, at which a quorum was present and acted throughout, adopted the
following resolution, which resolution remains in full force and effect on the
date hereof creating a series of Series A shares of preferred stock having a par
value of $.001 per share, designated as Series A Preferred Stock (the "Series A
Preferred Stock") out of the class of 5,000,000 shares of preferred stock, par
value $.001 per share (the "Preferred Stock"):

         RESOLVED, that pursuant to the authority vested in the Board of
Directors in accordance with the provisions of its Certificate, the Board of
Directors does hereby create, authorize and provide for the issuance of 200,000
shares of its authorized Preferred Stock to be designated and issued as the
Series A Preferred Stock, having the voting powers, designation, relative,
participating, optional and other special rights, preferences and
qualifications, limitations and restrictions that are set forth as follows:

         1. Dividends and Distributions. (A) Subject to the prior and superior
rights of the holders of any shares of any other series of Preferred Stock or
any other shares of stock of the Corporation ranking prior and superior to the
shares of Series A Preferred Stock with respect to dividends, each holder of one
one-hundredth (1/100) of a share (a "Unit") of Series A Preferred Stock shall be
entitled to receive, when, as and if declared by the Board of Directors out of
funds legally available for that purpose, (i) quarterly dividends payable in
cash on the first day of March, June, September and December in each year (each
such date being a "Quarterly Dividend Payment Date"), commencing on the first
Quarterly Dividend Payment Date after the first issuance of such Unit of Series
A Preferred Stock, in an amount per Unit (rounded to the nearest cent) equal to
the greater of (a) $.01 or (b) subject to the provision for adjustment
hereinafter set forth, the aggregate per share amount of all cash dividends
declared on shares of the Common Stock since the immediately preceding Quarterly
Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment
Date, since the first issuance of a Unit of Series A Preferred Stock, and (ii)
subject to the provision for adjustment hereinafter set forth, quarterly
distributions

                                      C-1
<PAGE>

(payable in kind) on each Quarterly Dividend Payment Date in an amount per Unit
equal to the aggregate per share amount of all non-cash dividends or other
distributions (other than a dividend payable in shares of Common Stock or a
subdivision of the outstanding shares of Common Stock, by reclassification or
otherwise) declared on shares of Common Stock since the immediately preceding
Quarterly Dividend Payment Date, or with respect to the first Quarterly Dividend
Payment Date, since the first issuance of a Unit of Series A Preferred Stock. In
the event that the Corporation shall at any time after September 25, 1998 (the
"Rights Declaration Date") (i) declare any dividend on outstanding shares of
Common Stock payable in shares of Common Stock, (ii) subdivide outstanding
shares of Common Stock or (iii) combine outstanding shares of Common Stock into
a smaller number of shares, then in each such case the amount to which the
holder of a Unit of Series A Preferred Stock was entitled immediately prior to
such event under clause (b) of the preceding sentence shall be adjusted by
multiplying such amount by a fraction the numerator of which shall be the number
of shares of Common Stock that are outstanding immediately after such event and
the denominator of which shall be the number of shares of Common Stock that were
outstanding immediately prior to such event.

         (B) The Corporation shall declare a dividend or distribution on Units
of Series A Preferred Stock as provided in paragraph (A) above immediately after
it declares a dividend or distribution on the shares of Common Stock (other than
a dividend payable in shares of Common Stock); provided, however, that, in the
event no dividend or distribution shall have been declared on the Common Stock
during the period between any Quarterly Dividend Payment Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $.01 per Unit on the
Series A Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

         (C) Dividends shall begin to accrue and shall be cumulative on each
outstanding Unit of Series A Preferred Stock from the Quarterly Dividend Payment
Date next preceding the date of issuance of such Unit of Series A Preferred
Stock, unless the date of issuance of such Unit is prior to the record date for
the first Quarterly Dividend Payment Date, in which case, dividends on such Unit
shall begin to accrue from the date of issuance of such Unit, or unless the date
of issuance is a Quarterly Dividend Payment Date or is a date after the record
date for the determination of holders of Units of Series A Preferred Stock
entitled to receive a quarterly dividend and before such Quarterly Dividend
Payment Date, in either of which events such dividends shall begin to accrue and
be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid
dividends shall not bear interest. Dividends paid on Units of Series A Preferred
Stock in an amount less than the aggregate amount of all such dividends at the
time accrued and payable on such Units shall be allocated pro rata on a
unit-by-unit basis among all Units of Series A Preferred Stock at the time
outstanding. The Board of Directors may fix a record date for the determination
of holders of Units of Series A Preferred Stock entitled to receive payment of a
dividend or distribution declared thereon, which record date shall be no more
than 30 days prior to the date fixed for the payment thereof.

         2. Voting Rights. The holders of Units of Series A Preferred Stock
shall have the following voting rights:

                                      C-2
<PAGE>

         (A) Subject to the provision for adjustment hereinafter set forth, each
Unit of Series A Preferred Stock shall entitle the holder thereof to one vote on
all matters submitted to a vote of the stockholders of the Corporation. In the
event the Corporation shall at any time after the Rights Declaration Date (i)
declare any dividend on outstanding shares of Common Stock payable in shares of
Common Stock, (ii) subdivide outstanding shares of Common Stock or (iii) combine
the outstanding shares of Common Stock into a smaller number of shares, then in
each such case the number of votes per Unit to which holders of Units of Series
A Preferred Stock were entitled immediately prior to such event shall be
adjusted by multiplying such number by a fraction the numerator of which shall
be the number of shares of Common Stock outstanding immediately after such event
and the denominator of which shall be the number of shares of Common Stock that
were outstanding immediately prior to such event; and

         (B) Except as otherwise provided herein, in the Certificate or the
Bylaws of the Corporation or as required by law, the holders of Units of Series
A Preferred Stock and the holders of shares of Common Stock shall vote together
as one class on all matters submitted to a vote of stockholders of the
Corporation, and such holders shall have no special voting rights and their
consents shall not be required for taking any corporate action.

         3. Certain Restrictions. (A) Whenever quarterly dividends or other
dividends or distributions payable on Units of Series A Preferred Stock as
provided herein are in arrears, thereafter and until all accrued and unpaid
dividends and distributions, whether or not declared, on outstanding Units of
Series A Preferred Stock shall have been paid in full, the Corporation shall not
(i) declare or pay dividends on, make any other distributions on, or redeem or
purchase or otherwise acquire for consideration any shares of junior stock; (ii)
declare or pay dividends on or make any other distributions on any shares of
parity stock, except dividends paid ratably on Units of Series A Preferred Stock
and shares of all such parity stock on which dividends are payable or in arrears
in proportion to the total amounts to which the holders of such Units and all
such shares are then entitled; (iii) redeem or purchase or otherwise acquire for
consideration shares of any parity stock, provided, however, that the
Corporation may at any time redeem, purchase or otherwise acquire shares of any
such parity stock in exchange for shares of any junior stock; (iv) purchase or
otherwise acquire for consideration any Units of Series A Preferred Stock,
except in accordance with a purchase offer made in writing or by publication (as
determined by the Board of Directors) to all holders of such Units.

         (B) The Corporation shall not permit any subsidiary of the Corporation
to purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (A) of this Section 3,
purchase or otherwise acquire such shares at such time and in such manner.

         4. Reacquired Shares. Any Units of Series A Preferred Stock purchased
or otherwise acquired by the Corporation in any manner whatsoever shall be
retired and cancelled promptly after the acquisition thereof. All such Units
shall, upon their cancellation, become authorized but unissued shares (or
fractions of shares) of Preferred Stock and may be reissued as part of a new
series of Preferred Stock to be created by resolution or resolutions of the
Board of Directors, subject to the conditions and restrictions on issuance set
forth herein.

                                      C-3
<PAGE>

         5. Liquidation, Dissolution or Winding Up. (A) Upon any voluntary or
involuntary liquidation, dissolution or winding up of the Corporation, no
distribution shall be made (i) to the holders of shares of junior stock unless
the holders of Units of Series A Preferred Stock shall have received, subject to
adjustment as hereinafter provided in paragraph (B), the greater of either (a)
$.01 per Unit plus an amount equal to accrued and unpaid dividends and
distributions thereon, whether or not earned or declared, to the date of such
payment, or (b) the amount equal to the aggregate per share amount to be
distributed to holders of shares of Common Stock, or (ii) to the holders of
shares of parity stock, unless simultaneously therewith distributions are made
ratably on Units of Series A Preferred Stock and all other shares of such parity
stock in proportion to the total amounts to which the holders of Units of Series
A Preferred Stock are entitled under clause (i)(a) of this sentence and to which
the holders of shares of such parity stock are entitled, in each case upon such
liquidation, dissolution or winding up.

         (B) In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on outstanding shares of Common Stock
payable in shares of Common Stock, (ii) subdivide outstanding shares of Common
Stock, or (iii) combine outstanding shares of Common Stock into a smaller number
of shares, then in each such case the aggregate amount to which holders of Units
of Series A Preferred Stock were entitled immediately prior to such event
pursuant to clause (i)(b) of paragraph (A) of this Section 5 shall be adjusted
by multiplying such amount by a fraction the numerator of which shall be the
number of shares of Common Stock that are outstanding immediately after such
event and the denominator of which shall be the number of shares of Common Stock
that were outstanding immediately prior to such event.

         6. Consolidation, Merger, etc. In case the Corporation shall enter into
any consolidation, merger, combination or other transaction in which the shares
of Common Stock are exchanged for or converted into other stock or securities,
cash and/or any other property, then in any such case Units of Series A
Preferred Stock shall at the same time be similarly exchanged for or converted
into an amount per Unit (subject to the provision for adjustment hereinafter set
forth) equal to the aggregate amount of stock, securities, cash and/or any other
property (payable in kind), as the case may be, into which or for which each
share of Common Stock is converted or exchanged. In the event the Corporation
shall at any time after the Rights Declaration Date (i) declare any dividend on
outstanding shares of Common Stock payable in shares of Common Stock, (ii)
subdivide outstanding shares of Common Stock, or (iii) combine outstanding
Common Stock into a smaller number of shares, then in each such case the amount
set forth in the immediately preceding sentence with respect to the exchange or
conversion of Units of Series A Preferred Stock shall be adjusted by multiplying
such amount by a fraction the numerator of which shall be the number of shares
of Common Stock that are outstanding immediately after such event and the
denominator of which shall be the number of shares of Common Stock that were
outstanding immediately prior to such event.

         7. Redemption. The Units of Series A Preferred Stock and shares of
Series A Preferred Stock shall not be redeemable.

         8. Ranking. The Units of Series A Preferred Stock and shares of Series
A Preferred Stock shall rank junior to all other series of the Preferred Stock
and to any other class of Preferred

                                      C-4
<PAGE>

Stock that hereafter may be issued by the Corporation as to the payment of
dividends and the distribution of assets, unless the terms of any such series or
class shall provide otherwise.

         9. Fractional Shares. The Series A Preferred Stock may be issued in
Units or other fractions of a share, which Units or fractions shall entitle the
holder, in proportion to such holder's units or fractional shares, to exercise
voting rights, receive dividends, participate in distributions and to have the
benefit of all other rights of holders of Series A Preferred Stock.

         10. Certain Definitions. As used in this resolution with respect to the
Series A Preferred Stock, the following terms shall have the following meanings:

         (A) The term "Common Stock" shall mean the class of stock designated as
the common stock, par value $.001 per share, of the Corporation at the date
hereof or any other class of stock resulting from successive changes or
reclassification of the common stock.

         (B) The term "junior stock" (i) as used in Section 3 shall mean the
Common Stock and any other class or series of capital stock of the Corporation
hereafter authorized or issued over which the Series A Preferred Stock has
preference or priority as to the payment of dividends and (ii) as used in
Section 5, shall mean the Common Stock and any other class or series of capital
stock of the Corporation over which the Series A Preferred Stock has preference
or priority in the distribution of assets on any liquidation, dissolution or
winding up of the Corporation.

         (C) The term "parity stock" (i) as used in Section 3 shall mean any
class or series of stock of the Corporation hereafter authorized or issued
ranking pari passu with the Series A Preferred Stock as to dividends and (ii) as
used in Section 5, shall mean any class or series of capital stock ranking pari
passu with the Series A Preferred Stock in the distribution of assets on any
liquidation, dissolution or winding up.

         IN WITNESS WHEREOF, Atrix Laboratories, Inc. has caused this
Certificate to be signed by its Assistant Secretary and Vice President, Finance
this 24th day of September, 1998.
