Item 1.     Description of Registrant's Securities to be Registered.

     On December 12, 1997, the Board of Directors of Rock Bottom Restaurants,
Inc. (the "Company") declared a dividend of one preferred stock purchase right
(a "Right") for each outstanding share of common stock, par value $.01 per
share, of the Company (the "Common Shares"). The Board of Directors of the
Company established that the dividend is payable on December 12, 1997 (the
"Record Date") to the stockholders of record on that date. Prior to the
Distribution Date (as defined below), the Rights will also be attached to all
future issuances of Common Shares. Each Right entitles the registered holder to
purchase from the Company one one-hundredth of a share of Series A Junior
Participating Preferred Stock, par value $.01 per share (the "Preferred
Shares"), of the Company at a price of $50 per one one-hundredth of a Preferred
Share (the "Purchase Price"), subject to adjustment. The description and terms
of the Rights are set forth in a Rights Agreement dated as of December 12, 1997
(the "Rights Agreement") by and between the Company and American Securities
Transfer & Trust, Incorporated, as Rights Agent (the "Rights Agent"). The
following description of the Rights and the Rights Agreement does not purport to
be complete and is qualified in its entirety by the form of Rights Agreement
attached as Exhibit 4.1, which is hereby incorporated herein by reference.

     The Rights will become exercisable on the date (the "Distribution Date")
that is the earlier of (i) 10 business days following a public announcement that
a person or group of affiliated or associated persons (an "Acquiring Person")
has acquired beneficial ownership of 15% or more of the outstanding Common
Shares (more than 50% in the case of the Company's Chairman of the Board, Frank
B. Day, his family and certain other entities to the extent that such entities
may be deemed to beneficially own Common Shares), (ii) 10 business days (or such
later date as may be determined by action of the Board of Directors prior to
such time as any person or group of affiliated persons becomes an Acquiring
Person) following the commencement or announcement of an intention to make a
tender offer or exchange offer the consummation of which would result in the
beneficial ownership by a person or group of 15% or more of the outstanding
Common Shares (more than 50% in the case of Mr. Day, his family and certain
other entities to the extent that such entities may be deemed to beneficially
own Common Shares), or (iii) 10 business days after a change in the composition
of the Board over a period of 18 consecutive months or less such that fifty
percent (50%) or more of the members of Board of Directors who were directors at
the beginning of such 18-month period cease to be directors during such period,
and are replaced by directors that have not been unanimously elected or
nominated by persons who were directors at the commencement of such 18-month
period or other directors so elected or nominated. The Rights will be evidenced,
with respect to any of the Common Share certificates outstanding as of the
Record Date, by such Common Share certificate.

     The Rights Agreement provides that, until the Distribution Date (or earlier
redemption or expiration of the Rights): (i) the Rights will be transferred with
and only with the Common Shares; (ii) new Common Share certificates issued after
the Record Date upon transfer or new issuances of Common Shares will contain a
notation incorporating the Rights Agreement by reference; and (iii) the
surrender for transfer of any certificates for Common Shares outstanding as of
the Record Date, even without such notation, will also constitute the transfer
of the Rights 




                                     -2-

<PAGE>



associated with the Common Shares represented by such certificate. As soon as
practicable following the Distribution Date, separate certificates evidencing
the Rights ("Right Certificates") will be mailed to holders of record of the
Common Shares as of the close of business on the Distribution Date and
thereafter such separate Right Certificates alone will evidence the Rights. The
Rights Agreement provides that anything therein or in the Rights to the contrary
notwithstanding, Rights may be issued subsequent to the Distribution Date under
certain circumstances as set forth in the Rights Agreement.

     The Rights are not exercisable until the Distribution Date. The Rights will
expire on December 12, 2007 (the "Final Expiration Date"), unless the Final
Expiration Date is extended or unless the Rights are earlier redeemed or
exchanged by the Company, in each case as described below.

     The Purchase Price payable, and the number of Preferred Shares or other
securities or property 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
Shares, (ii) upon the grant to holders of the Preferred Shares of certain rights
or warrants to subscribe for or purchase Preferred Shares at a price, or
securities convertible into Preferred Shares with a conversion price, less than
the then-current market price of the Preferred Shares or (iii) upon the
distribution to holders of the Preferred Shares of evidence of indebtedness or
assets (excluding regular periodic cash dividends paid out of earnings or
retained earnings or dividends payable in Preferred shares) or of subscription
rights or warrants (other than those referred to above).

     The number of outstanding Rights are also subject to adjustment in the
event of a stock split of the Common Shares or a stock dividend on the Common
Shares payable in Common Shares or subdivisions, consolidations or combinations
of the Common shares occurring, in any such case, prior to the Distribution
Date.

     Preferred Shares purchasable upon exercise of the Rights will not be
redeemable. Each Preferred Share will be entitled to a preferential semi-annual
dividend payment, when, as and if declared by the Company's Board of Directors,
of the greater of $1 per share or 100 times the dividend declared per Common
Share. In the event of liquidation, the holders of the Preferred Shares will be
entitled to a preferential liquidation payment of the greater of $100 per share
or 100 times the payment made per Common Share. Each Preferred Share will have
100 votes, voting together with the Common Shares. These rights are protected by
customary antidilution provisions.

     Because of the nature of the Preferred Shares' dividend, liquidation and
voting rights, the value of the one one-hundredth interest in a Preferred Share
purchasable upon exercise of each Right should approximate the value of one
Common Share.

     In the event that any person or group of affiliated or associated persons
becomes an Acquiring Person, each holder of a Right (other than Rights
beneficially owned by the Acquiring Person, which will become void), will
thereafter have the right to receive upon exercise that number 






                                     -3-

<PAGE>

of shares of Common Stock (or that number of one one-hundredths of a Preferred
Share or of a share of a class or series of the Company's preferred stock having
equivalent rights, preferences and privileges) having a market value of two
times the exercise price of the Right.

     In the event that, after a person or group has become an Acquiring Person,
the Company is acquired in a merger or other business combination transaction or
50% or more of its consolidated assets or earning power are sold, proper
provision will be made so that each holder of a Right (other than Rights
beneficially owned by an Acquiring Person which will have become void) will
thereafter have the right to receive, upon the exercise thereof at the then
current exercise price, that number of shares of common stock of the acquiring
company which at the time of such transaction will have a market value of two
times the exercise price of the Right.

     With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price. No fractional Preferred Shares will be issued (other than
fractions which are integral multiples of one one-hundredth of a Preferred
Share, which may, at the election of the Company, be evidenced by depositary
receipts) and in lieu thereof, an adjustment in cash will be made based on the
market price of the Preferred Shares on the last trading day prior to the date
of exercise.

     At any time prior to the time any person becomes an Acquiring Person, the
Board of Directors of the Company may redeem the Rights in whole, but not in
part, at a price of $.001 per Right (the "Redemption Price"). The redemption of
the Rights may be made effective at such time, on such basis an with such
conditions as the Board of Directors in its sole discretion may establish.
Immediately upon any redemption of the Rights, the right to exercise the Rights
will terminate and the only right of the holders of Rights will be to receive
the Redemption Price.

     At any time after any person or group becomes an Acquiring Person and prior
to the acquisition by such person or group of 50% or more of the outstanding
Common Shares, the Board of Directors of the Company may exchange the Rights
(other than Rights owned by such person or group which will have become void),
in whole or in part, at an exchange ratio of one share of Common Stock, or one
one-hundredth of a Preferred Share (or of a share of a class or series of the
Company's preferred stock having equivalent rights, preferences and privileges),
per Right (subject to adjustment).

     For so long as Rights are then redeemable, the Company may, except with
respect to the redemption price, amend the Rights in any manner. After the
Rights are no longer redeemable, the Company may amend the Rights in any manner
that does not adversely affect the interests of holders of the Rights or cause
the Rights again to become redeemable.

     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.

                               RIGHTS AGREEMENT

            Agreement, dated as of December 12, 1997, between Rock Bottom
Restaurants, Inc., a Delaware corporation (the "Company"), and American
Securities Transfer & Trust, Incorporated (the "Rights Agent").

            The Board of Directors of the Company has authorized and declared a
dividend of one preferred stock purchase right (a "Right") for each Common Share
(as hereinafter defined) of the Company outstanding as of the close of business
(as defined below) on December 12, 1997 (the "Record Date"), each Right
representing the right to purchase one one-hundredths (subject to adjustment) of
a Preferred Share (as hereinafter defined), upon the terms and subject to the
conditions herein set forth, and has further authorized and directed the
issuance of one Right (subject to adjustment as provided herein) with respect to
each Common Share (as defined below) that shall become outstanding between the
Record Date and the earliest of the Distribution Date, the Redemption Date and
the Final Expiration Date (as such terms are hereinafter defined); provided,
however, that Rights may be issued with respect to Common Shares that shall
become outstanding after the Distribution Date and prior to the Redemption Date
and the Final Expiration Date in accordance with Section 22.

            Accordingly, 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 meaning indicated:

                  (a) "Acquiring Person" shall mean any Person (as such term is
hereinafter defined) who or which, without the prior approval of the Company,
shall be the Beneficial Owner (as such term is hereinafter defined) of 15% or
more of the Common Shares then outstanding, but shall not include an Exempt
Person (as such term is hereinafter defined); provided, however, that if the
Board of Directors of the Company determines in good faith that a Person who
would otherwise be an "Acquiring Person," has become such inadvertently, and
such Person divests himself or itself as promptly as practicable of beneficial
ownership of a sufficient number of Common Shares so that such Person would no
longer be an Acquiring Person, then such Person shall not be deemed to be or
have become an "Acquiring Person" for any purposes of this Agreement.
Notwithstanding the foregoing, no Person shall become an "Acquiring Person" as
the result of an acquisition of Common Shares by the Company which, by reducing
the number of shares outstanding, increases the proportionate number of shares
beneficially owned by such Person to 15% or more of the Common Shares then
outstanding, provided, however, that if a Person shall become the Beneficial
Owner of 15% or more of the Common Shares then outstanding by reason of such
share acquisitions by the Company and thereafter become the Beneficial Owner of
any additional Common Shares, then such Person shall be deemed to be an
"Acquiring Person" unless upon the consummation of the acquisition of such
additional Common Shares such Person does not beneficially own 15% or more of
the Common Shares then outstanding. The phrase "then outstanding," when used
with reference to a Person's Beneficial Ownership of securities of the Company,
shall mean the number of such securities then issued and outstanding together
with the number of such securities not then





<PAGE>



actually issued and outstanding which such Person would be deemed to own
beneficially hereunder.

                  (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 of this Agreement.

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

                         (i) which such Person or any of such Person's
Affiliates or Associates is deemed to beneficially own, directly or indirectly
within the meaning of Rule 13d-3 of the General Rules and Regulations under the
Exchange Act as in effect on the date of this Rights Agreement;

                         (ii) which such Person or any of such Person's
Affiliates or Associates has (A) the right to acquire (whether such right is
exercisable immediately or only after the passage of time) pursuant to any
agreement, arrangement or understanding (other than customary agreements with
and between underwriters and selling group members with respect to a bona fide
public offering of securities), or upon the exercise of conversion rights,
exchange rights, rights, warrants or options, or otherwise; provided, however,
that a Person shall not be deemed the Beneficial Owner of, or to beneficially
own, (x) securities tendered pursuant to a tender or exchange offer made by or
on behalf of such Person or any of such Person's Affiliates or Associates until
such tendered securities are accepted for purchase, (y) securities which such
Person has a right to acquire on the exercise of Rights at any time prior to the
time a Person becomes an Acquiring Person or (z) securities issuable upon
exercise of Rights from and after the time a Person becomes an Acquiring Person
if such 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(b) or
Section 22 hereof ("Original Rights") or pursuant to Section 11(i) or Section
11(n) with respect to an adjustment to Original Rights; or (B) the right to vote
pursuant to any agreement, arrangement or understanding; provided, however, that
a Person shall not be deemed the Beneficial Owner of, or to beneficially own,
any security by reason of such agreement, arrangement or understanding if the
agreement, arrangement or understanding to vote such security (1) arises solely
from a revocable proxy or consent given to such Person in response to a public
proxy or consent solicitation made pursuant to, and in accordance with, the
applicable rules and regulations promulgated under the Exchange Act and (2) is
not also then reportable on Schedule 13D under the Exchange Act (or any
comparable or successor report); or

                        (iii) which are beneficially owned, directly or
indirectly, by any other Person with which such Person or any of such Person's
Affiliates or Associates has any agreement, arrangement or understanding (other
than customary agreements with and between underwriters and selling group
members with respect to a bona fide public offering of securities) for the
purpose of acquiring, holding, voting (except to the extent contemplated by the
proviso to Section 1(c)(ii)(B)) or disposing of shares of the Common Stock.

<PAGE>



                  (d) "Business Day" shall mean any day other than a Saturday, a
Sunday, or a day on which banking institutions in the State of Colorado are
authorized or obligated by law or executive order to close.

                  (e) "Close of Business" on any given date shall mean 5:00
P.M., Denver time, on such date; provided, however, that if such date is not a
Business Day it shall mean 5:00 P.M., Denver time, on the next succeeding
Business Day.

                  (f) "Common Shares" when used with reference to the Company
shall mean shares of Common Stock of the Company. "Common Shares" when used with
reference to any Person other than the Company shall mean the capital stock (or,
in the case of an unincorporated entity, the equivalent equity interest) with
the greatest voting power of such other Person or, if such other Person is a
subsidiary of another Person, the Person or Persons which ultimately control
such first-mentioned Person.

                  (g) "Common Stock" shall mean the common stock, presently par
value $.01 per share, of the Company.

                  (h) "Current Value" shall have the meaning set forth in
Section 11(a)(iii) hereof.

                  (i)   "Distribution Date" shall have the meaning set forth in
Section 3 hereof.

                  (j) "Exempt Person" shall mean the Company, any Subsidiary (as
such term is hereinafter defined) of the Company, any employee benefit plan of
the Company or of any Subsidiary of the Company, any entity or trustee holding
Common Shares for or pursuant to the terms of any such plan or for the purpose
of funding any such plan or funding other employee benefits for employees of the
Company or of any Subsidiary of the Company, any Grandfathered Person (as such
term is hereinafter defined); provided, however, that a Grandfathered Person
shall not be deemed to be Exempt Person if, without the prior approval of the
Company, such Grandfathered Person becomes the Beneficial Owner of 50% or more
of the Common Shares then outstanding. Notwithstanding the foregoing, no
Grandfathered Person shall cease to be deemed an Exempt Person as the result of
an acquisition of Common Shares by the Company which, by reducing the number of
shares outstanding, increases the proportionate number of shares beneficially
owned by such Grandfathered Person to 50% or more of the Common Shares then
outstanding; provided, however, that if any Grandfathered Person shall become
the Beneficial Owner of 50% or more of the Common Shares then outstanding by
reason of such share acquisitions by the Company and thereafter becomes the
Beneficial Owner of any additional Common Shares, then such Grandfathered Person
shall not be deemed to be an Exempt Person unless upon the consummation of the
acquisition of such additional Common Shares such Grandfathered Person does not
beneficially own 50% or more of the Common Shares then outstanding.

                  (k) "Final Expiration Date" shall have the meaning set forth
in Section 7 hereof.

                  (l)   "Flip In Event" shall have the meaning set forth in
Section 11(a)(ii) hereof.

                  (b) Until the Distribution Date (i) the Rights will be
evidenced (subject to the provisions of Section 3(c) hereof) by the certificates
for Common Shares registered in the names of the holders thereof and not by
separate Right Certificates, and (ii) the Rights will be transferable only in
connection with the transfer of the associated Common Shares. As soon as
practicable after the Distribution Date, the Company will prepare and execute,
the Rights Agent will countersign, and the Company will send or cause to be sent
(and the Rights Agent will, if requested, send) by first-class, postage-prepaid
mail, to each record holder of Common Shares as of the close of business on the
Distribution Date (other than any Acquiring Person or any Associate or Affiliate
of an Acquiring Person), at the address of such holder shown on the records of
the Company, a Right Certificate, in substantially the form of EXHIBIT B hereto
(a "Right Certificate"), evidencing one Right (subject to adjustment as provided
herein) for each Common Share so held. As of the Distribution Date, the Rights
will be evidenced solely by such Right Certificates.

                  (c) With respect to certificates for Common Shares 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. Until the
Distribution Date (or the earlier of the Redemption Date or the Final Expiration
Date), the surrender for transfer of any certificate for Common Shares
outstanding on the Record Date shall also constitute the transfer of the Rights
associated with the Common Shares represented thereby.

                  (d) Certificates issued for Common Shares (including, without
limitation, upon transfer of outstanding Common Shares, disposition of Common
Shares out of treasury stock or issuance or reissuance of Common Shares out of
authorized but unissued shares) after the Record Date but prior to the earliest
of the Distribution Date, the Redemption Date or the Final Expiration Date shall
have impressed on, printed on, written on or otherwise affixed to them the
following legend:

          This certificate also evidences and entitles the holder hereof to
          certain rights as set forth in a Rights Agreement between Rock Bottom
          Restaurants, Inc. and American Securities Transfer & Trust,
          Incorporated, dated as of December 12, 1997 (the "Rights Agreement")
          as the same may be amended from time to time, the terms of which are
          hereby incorporated herein by reference and a copy of which is on file
          at the principal executive offices of Rock Bottom Restaurants, Inc.
          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


                                    -6-

<PAGE>


          certificate. Rock Bottom Restaurants, Inc. will mail to the holder of
          this certificate a copy of the Rights Agreement without charge after
          receipt of a written request therefor. Under certain circumstances, as
          set forth in the Rights Agreement, Rights owned by or transferred to
          any Person who becomes an Acquiring Person (as defined in the Rights
          Agreement) and certain transferees thereof will become null and void
          and will no longer be transferable.

With respect to such certificates containing the foregoing legend, until the
Distribution Date, the Rights associated with the Common Shares represented by
such certificates shall be evidenced by such certificates alone, and the
surrender for transfer of any such certificate, except as otherwise provided
herein, shall also constitute the transfer of the Rights associated with the
Common Shares represented thereby. In the event that the Company purchases or
otherwise acquires any Common Shares after the Record Date but prior to the
Distribution Date, any Rights associated with such Common Shares shall be deemed
canceled and retired so that the Company shall not be entitled to exercise any
Rights associated with the Common Shares which are no longer outstanding.

            Notwithstanding this paragraph (d), the omission of a legend shall
not affect the enforceability of any part of this Rights Agreement or the rights
of any holder of the Rights.

            Section 4. FORM OF RIGHT CERTIFICATES. The Right Certificates (and
the forms of election to purchase Preferred Shares and of assignment to be
printed on the reverse thereof) shall be substantially in the form set forth in
EXHIBIT B 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 with any rule or
regulation made pursuant thereto or with any rule or regulation of the NASDAQ
Stock Market or of any stock exchange on which the Rights may from time to time
be listed, or to conform to usage. Subject to the provisions of Sections 11 and
22 hereof, the Right Certificates shall entitle the holders thereof to purchase
such number of one one-hundredths of a Preferred Share as shall be set forth
therein at the price per one one-hundredths of a Preferred Share set forth
therein (the "Purchase Price"), but the number of such one one-hundredths of a
Preferred Share and the Purchase Price shall be subject to adjustment as
provided herein.

            Section 5.  COUNTERSIGNATURE AND REGISTRATION.

                  (a) The Right Certificates shall be executed on behalf of the
Company by the Chairman of the Board of Directors, the Chief Executive Officer,
the President, any of the Vice Presidents, the Treasurer or the Controller of
the Company, either manually or by facsimile signature, shall have affixed
thereto the Company's seal or a facsimile thereof, and shall be attested by the
Secretary or an Assistant Secretary of the Company, either manually or by
facsimile signature. The Right Certificates shall be manually countersigned by
the Rights Agent and shall not be valid for any purpose unless countersigned. In
case any officer of the Company who shall have signed any of the Right
Certificates shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the 


                                    -7-

<PAGE>



Company, such Right Certificates, nevertheless, may be countersigned by the
Rights Agent and issued and delivered by the Company with the same force and
effect as though the Person who signed such Right Certificates had not ceased to
be such officer of the Company; and any Right Certificate may be signed on
behalf of the Company by any Person who, at the actual date of the execution of
such Right Certificate, shall be a proper officer of the Company to sign such
Right Certificate, although at the date of the execution of this Rights
Agreement any such Person was not such an officer.

                  (b) Following the Distribution Date, the Rights Agent will
keep or cause to be kept, at an office or agency designated for such purpose,
books for registration and transfer of the Right Certificates issued hereunder.
Such books shall show the names and addresses of the respective holders of the
Right Certificates, the number of Rights evidenced on its face by each of the
Right Certificates and the date of each of the Right Certificates.

            Section 6.  TRANSFER, SPLIT UP, COMBINATION AND EXCHANGE OF RIGHT
CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHT CERTIFICATES.

                  (a) Subject to the provisions of Sections 11(a)(ii) 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 earlier of the Redemption Date or the
Final Expiration Date, any Right Certificate or Right Certificates (other than
Right Certificates representing Rights that have become void pursuant to Section
11(a)(ii) hereof or that have been exchanged pursuant to Section 24 hereof) may
be transferred, split up, combined or exchanged for another Right Certificate or
Right Certificates, entitling the registered holder to purchase a like number of
one one-hundredths of a Preferred Share as the Right Certificate or Right
Certificates surrendered then entitled such holder to purchase. Any registered
holder desiring to transfer, split up, combine or exchange any Right Certificate
or Right Certificates shall make such request in writing delivered to the Rights
Agent, and shall surrender the Right Certificate or Right Certificates to be
transferred, split up, combined or exchanged at the office or agency of the
Rights Agent designated for such purpose. Thereupon the Rights Agent shall
countersign and deliver to the Person entitled thereto a Right Certificate or
Right 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
Right Certificates.

                  (b) Subject to the provisions of Section 11(a)(ii) hereof,
upon receipt by the Company and the Rights Agent of evidence reasonably
satisfactory to them of the loss, theft, destruction or mutilation of a Right
Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to them, and, at the Company's request,
reimbursement to the Company and the Rights Agent of all reasonable expenses
incidental thereto, and upon surrender to the Rights Agent and cancellation of
the Right Certificate if mutilated, the Company will make and deliver a new
Right Certificate of like tenor to the Rights Agent for delivery to the
registered holder in lieu of the Right Certificate so lost, stolen, destroyed or
mutilated.

            Section 7.  EXERCISE OF RIGHTS, PURCHASE PRICE; EXPIRATION DATE OF
RIGHTS.

                  (a) Except as otherwise provided herein, the Rights shall
become exercisable on the Distribution Date, and thereafter the registered
holder of any Right Certificate may exercise the Rights evidenced thereby
(except as otherwise provided herein) in whole or in part, upon surrender of the
Right Certificate, with the form of election to purchase on the reverse side
thereof duly executed, to the Rights Agent at the office or agency of the Rights
Agent designated for such purpose, together with payment of the Purchase Price
for each one one-hundredths of a Preferred Share as to which the Rights are
exercised, at any time which is both after the Distribution Date and prior to
the earliest of (i) 5:00 p.m., Denver time, on December 12, 2007 (the "Final
Expiration Date"), (ii) the time at which the Rights are redeemed as provided in
Section 23 hereof (the "Redemption Date") or (iii) the time at which such Rights
are exchanged as provided in Section 24 hereof.

                  (b) The Purchase Price shall be initially $50 for each one
one-hundredths of a Preferred Share purchasable upon the exercise of a Right.
The Purchase Price and the number of one one-hundredths of a Preferred Share or
other securities or property to be acquired upon exercise of a Right shall be
subject to adjustment from time to time as provided in Sections 11 and 13 hereof
and shall be payable in lawful money of the United States of America in
accordance with paragraph (c) of this Section 7.

                  (c) Except as otherwise provided herein, upon receipt of a
Right Certificate representing exercisable Rights, with the form of election to
purchase duly executed, accompanied by payment of the aggregate Purchase Price
for the Preferred Shares to be purchased and an amount equal to any applicable
transfer tax required to be paid by the holder of such Right Certificate in
accordance with Section 9 hereof, in cash or by certified check, cashier's check
or money order payable to the order of the Company, the Rights Agent shall
thereupon promptly (i) (A) requisition from any transfer agent of the Preferred
Shares certificates for the number of Preferred Shares to be purchased and the
Company hereby irrevocably authorizes its transfer agent to comply with all such
requests, or (B) requisition from the depositary agent depositary receipts
representing interests in such number of one one-hundredths of a Preferred Share
as are to be purchased (in which case certificates for the Preferred Shares
represented by such receipts shall be deposited by the transfer agent with the
depositary agent) and the Company hereby directs the depositary agent to comply
with such request, (ii) when appropriate, requisition from the Company the
amount of cash to be paid in lieu of issuance of fractional shares in accordance
with Section 14 hereof, (iii) promptly after receipt of such certificates or
depositary receipts, cause the same to be delivered to or upon the order of the
registered holder of such Right Certificate, registered in such name or names as
may be designated by such holder and (iv) when appropriate, after receipt,
promptly deliver cash to be paid in lieu of fractional shares to or upon the
order of the registered holder of such Right Certificate.

                  (d) Except as otherwise provided herein, in case the
registered holder of any Right Certificate shall exercise less than all the
Rights evidenced thereby, a new Right Certificate evidencing Rights equivalent
to the Rights remaining unexercised shall be issued by the Rights Agent to the
registered holder of such Right Certificate or to his duly authorized assigns,
subject to the provisions of Section 14 hereof.

                  (e) Notwithstanding anything in this Rights Agreement 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 as set forth in this Section 7 unless such registered
holder shall have (i) completed and signed the certificate contained in 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
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or 
Associates thereof as the Company shall reasonably request.

            Section 8. CANCELLATION AND DESTRUCTION OF RIGHT CERTIFICATES. All
Right Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or to 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 Right
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this Rights Agreement. The Company shall deliver to the
Rights Agent for cancellation and retirement, and the Rights Agent shall so
cancel and retire, any other Right Certificate purchased or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall deliver
all cancelled Right Certificates to the Company, or shall, at the written
request of the Company, destroy such cancelled Right Certificates, and in such
case shall deliver a certificate of destruction thereof to the Company.

            Section 9.  AVAILABILITY OF PREFERRED SHARES.

                  (a) The Company covenants and agrees that it will cause to be
reserved and kept available out of its authorized and unissued Preferred Shares
or any Preferred Shares held in its treasury, the number of Preferred Shares
that will be sufficient to permit the exercise in full of all outstanding
Rights.

                  (b) So long as the Preferred Shares (and, following the time
that a Person becomes an Acquiring Person, shares of Common Stock and other
securities) issuable upon the exercise of Rights may be listed or admitted to
trading on the NASDAQ Stock Market or listed on any national securities
exchange, the Company shall use its best efforts to cause, from and after such
time as the Rights become exercisable, all shares reserved for such issuance to
be listed or admitted to trading on the NASDAQ Stock Market or listed on such
exchange upon official notice of issuance upon such exercise.

                  (c) From and after such time as the Rights become exercisable,
the Company shall use its best efforts to, if then necessary to permit the
issuance of Preferred Shares (and following the time that a Person first becomes
an Acquiring Person, shares of Common Stock and other securities) upon the
exercise of Rights, register and qualify such Preferred Shares (and following
the time that a Person first becomes an Acquiring Person, shares of Common Stock
and other securities) under the Securities Act and any applicable state
securities or "Blue Sky" laws (to the extent exemptions therefrom are not
available), cause such registration statement and qualifications to become
effective as soon as possible after such filing, keep such registration and
qualifications effective until the earlier of the date as of which the Rights
are no longer exercisable for such securities and the Final Expiration Date, and
comply with any requirements of the NASDAQ Stock Market (or any national
securities exchange on 


                                    -10-

<PAGE>


which such securities may be listed for trading) applicable to the Company. The
Company may temporarily suspend, for a period of time not to exceed 90 days, the
exercisability of the Rights in order to prepare and file a registration
statement under the Securities Act and permit it to become effective, to comply
with any applicable state securities or "Blue Sky" laws, or to comply with any
requirements of the NASDAQ Stock Market applicable to the Company. 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.
Notwithstanding any provision of this Agreement to the contrary, the Rights
shall not be exercisable in any jurisdiction unless the requisite qualification
in such jurisdiction shall have been obtained and until a registration statement
under the Securities Act (if required) shall have been declared effective and
any requirements of the NASDAQ Stock Market (or any national securities exchange
on which such securities may be listed for trading) applicable to the Company
have been satisfied.

                  (d) The Company covenants and agrees that it will take all
such action as may be necessary to ensure that all Preferred Shares (and,
following the time that a Person becomes an Acquiring Person, shares of Common
Stock and other securities) delivered upon exercise of Rights shall, at the time
of delivery of the certificates therefor (subject to payment of the Purchase
Price), be duly and validly authorized and issued and fully paid and
nonassessable shares.

                  (e) The Company further covenants and agrees that it will pay
when due and payable any and all federal and state transfer taxes and charges
which may be payable in respect of the issuance or delivery of the Right
Certificates or of any Preferred Shares (or shares of Common Stock or other
securities) upon the exercise of Rights. The Company shall not, however, be
required to pay any transfer tax which may be payable in respect of any transfer
or delivery of Right Certificates to a Person other than, or the issuance or
delivery of certificates or depositary receipts for the Preferred Shares in a
name other than that of, the registered holder of the Right Certificate
evidencing Rights surrendered for exercise or to issue or deliver any
certificates or depositary receipts for Preferred Shares upon the exercise of
any Rights until any such tax shall have been paid (any such tax being payable
by that holder of such Right Certificate at the time of surrender) or until it
has been established to the Company's reasonable satisfaction that no such tax
is due.

            Section 10. PREFERRED SHARES RECORD DATE. Each Person in whose name
any certificate for Preferred Shares is issued upon the exercise of Rights shall
for all purposes be deemed to have become the holder of record of the Preferred
Shares represented thereby on, and such certificate shall be dated, the date
upon which the Right 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 Shares transfer books of the Company are closed, such Person
shall be deemed to have become the record holder of such shares on, and such
certificate shall be dated, the next succeeding Business Day on which the
Preferred Shares transfer books of the Company are open. Prior to the exercise
of the Rights evidenced thereby, the holder of a Right Certificate shall not be
entitled to any rights of a holder of Preferred Shares for which the Rights
shall be exercisable, including, without limitation, the right to vote, to
receive dividends or other

                                    -11-

<PAGE>

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 OF SHARES OR NUMBER
OF RIGHTS. The Purchase Price, the number of Preferred Shares or other
securities or property 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
            Shares payable in Preferred Shares, (B) subdivide the outstanding
            Preferred Shares, (C) combine the outstanding Preferred Shares into
            a smaller number of Preferred Shares or (D) issue any shares of its
            capital stock in a reclassification of the Preferred Shares
            (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 capital stock issuable on such date, shall be proportionately
            adjusted so that the holder of any Right exercised after such time
            shall be entitled to receive the aggregate number and kind of shares
            of capital stock which, if such Right had been exercised immediately
            prior to such date and at a time when the Preferred Shares transfer
            books of the Company were open, the 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 exercise of
            one Right.

                         (ii) Subject to Section 24 of this Agreement and except
            as otherwise provided in this Section 11(a)(ii), in the event any
            Person becomes an Acquiring Person (the first occurrence of such
            event being referred to as the "Flip In Event"), each holder of a
            Right, shall thereafter have the right to receive, upon exercise
            thereof at a price equal to the Purchase Price immediately prior to
            the Flip In Event multiplied by the number of one one-hundredths of
            a Preferred Share for which a Right was exercisable immediately
            prior to such event, whether or not such Right was then exercisable,
            in accordance with the terms of this Agreement and in lieu of
            Preferred Shares, such number of Common Shares (or at the option of
            the Company, such number of one one-hundredths of Preferred Shares)
            as shall equal the result obtained by (x) multiplying the Purchase
            Price immediately prior to the Flip

            In Event by the number of one one-hundredths of a Preferred Share
            for which a Right was exercisable immediately prior to such
            event, whether or not such Right was then exercisable, and (y)
            dividing that product by 50% of the then current per share market
            price of the Company's Common Stock (determined pursuant to
            Section 11(d) hereof) on the date of the occurrence of such
            event. Notwithstanding anything in this Rights Agreement to the
            contrary, however, from and after the Flip In Event, any Rights
            that are beneficially owned by (x) any Acquiring Person (or any
            Affiliate or Associate of any Acquiring Person), (y) a transferee
            of any Acquiring Person (or any such Affiliate or Associate) who
            becomes a transferee after the Flip In Event or (z) a transferee
            of any Acquiring Person (or any such Affiliate or Associate) who
            became a transferee prior to or concurrently with the Flip In
            Event pursuant to either (I) a transfer from the Acquiring Person
            to holders of its equity securities or to any Person with whom it
            has any continuing agreement, arrangement or understanding
            regarding the transferred Rights or (II) a transfer which the
            Board of Directors has determined is part of a plan, arrangement
            or understanding which has the purpose or effect of avoiding the
            provisions of this paragraph, and subsequent transferees of such
            Persons, shall be void without any further action and any holder
            of such Rights shall thereafter have no rights whatsoever with
            respect to such Rights under any provision of this Rights
            Agreement. The Company shall use all reasonable efforts to ensure
            that the provisions of this Section 11(a)(ii) are complied with,
            but shall have no liability to any holder of Right Certificates
            or other Person as a result of its failure to make any
            determinations with respect to an Acquiring Person or its
            Affiliates, Associates or transferees hereunder. From and after
            the Flip In Event, no Right Certificate shall be issued pursuant
            to Section 3 or Section 6 hereof that represents Rights that are
            or have become void pursuant to the provisions of this paragraph,
            and any Right Certificate delivered to the Rights Agent that
            represents Rights that are or have become void pursuant to the
            provisions of this paragraph shall be canceled. From and after
            the occurrence of an event specified in Section 13(a) hereof, any
            Rights that theretofore have not been exercised pursuant to this
            Section 11(a)(ii) shall thereafter be exercisable only in
            accordance with Section 13 and not pursuant to this Section
            11(a)(ii).

                        (iii) The Company may at its option substitute for a
            share of Common Stock issuable upon the exercise of Rights in
            accordance with the foregoing subparagraph (ii) such number of
            fractions of Preferred Shares having an aggregate current market
            value equal to the current per share market price of a share of
            Common Stock. In the event that there shall not be sufficient 

                                    -13-

<PAGE>


            shares of Common Stock issued but not outstanding or authorized but
            unissued to permit the exercise in full of the Rights in accordance
            with the foregoing subparagraph (ii), 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 (A)
            determine the excess of (1) the value of the shares of Common Stock
            issuable upon the exercise of a Right in accordance with the
            foregoing subparagraph (ii) (the "Current Value") over (2) the
            Purchase Price immediately prior to the Flip In Event multiplied by
            the number of one one-hundredths of Preferred Shares for which a
            Right was exercisable immediately prior to such event, whether or
            not such Right was then exercisable (such excess, the "Spread"), and
            (B) with respect to each Right (other than Rights which have become
            void pursuant to Section 11(a)(ii)), make adequate provision to
            substitute for the shares of Common Stock issuable in accordance
            with subparagraph (ii) upon exercise of the Right and payment of the
            applicable Purchase Price, (1) cash, (2) a reduction in the Purchase
            Price, (3) Preferred Shares or other equity securities of the
            Company (including, without limitation, shares or fractions of
            shares of preferred stock which, by virtue of having dividend,
            voting and liquidation rights substantially comparable to those of
            the shares of Common Stock, are deemed in good faith by the Board of
            Directors to have substantially the same value as the shares of
            Common Stock (such Preferred Shares and shares or fractions of
            shares of preferred stock are hereinafter referred to as "Common
            Share equivalents"), (4) debt securities of the Company, (5) other
            assets, or (6) any combination of the foregoing, having a value
            which, when added to the value of the shares of Common 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 the Purchase Price), where such aggregate value has been
            determined by the Board of Directors upon the advice of a nationally
            recognized investment banking firm selected in good faith by the
            Board of Directors; provided, however, if the Company shall not make
            adequate provision to deliver value pursuant to Clause (B) above
            within thirty (30) days following the Flip In Event (the "Section
            11(a)(ii) Trigger Date"), then the Company shall be obligated to
            deliver, to the extent permitted by applicable law and any material
            agreements then in effect to which the Company is a party, upon the
            surrender or exercise of a Right and without requiring payment of
            the Purchase Price, shares of Common Stock (to the extent
            available), and then, if necessary, such number or fractions of
            Preferred Shares (to the extent available) and then, if necessary,
            cash, which shares and/or cash have an aggregate value equal to the
            Spread. If, upon the occurrence of the Flip In Event, the Board of
            Directors shall determine in good faith that it is likely that
            

                                    -14-

<PAGE>


            sufficient additional shares of Common Stock could be authorized for
            issuance upon exercise in full of the Rights, then, if the Board of
            Directors so elects, the thirty (30) day period set forth above may
            be extended to the extent necessary, but not more than ninety (90)
            days after the Section 11(a)(ii) Trigger Date, in order that the
            Company may seek stockholder approval for the authorization of such
            additional shares (such thirty (30) day period, as it may be
            extended, is herein called the "Substitution Period"). To the extent
            that the Company determines that some action need be taken pursuant
            to the second and/or third sentence of this Section 11(a)(iii), the
            Company (x) shall provide, subject to Section 11(a)(ii) hereof and
            the last sentence of this Section 11(a)(iii) hereof, that such
            action shall apply uniformly to all outstanding Rights and (y) may
            suspend the exercisability of the Rights until the expiration of the
            Substitution Period in order to seek any authorization of additional
            shares and/or to decide the appropriate form of distribution to be
            made pursuant to such second sentence and to determine the value
            thereof. In the event of 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.
            For purposes of this Section 11(a)(iii), the value of the shares of
            Common Stock shall be the current per share market price (as
            determined pursuant to Section 11(d)(i)) on the Section 11(a)(ii)
            Trigger Date and the per share or fractional value of any "Common
            Share equivalent" shall be deemed to equal the current per share
            market price of the Common Shares. The Board of Directors of the
            Company may, but shall not be required to, establish procedures to
            allocate the right to receive shares of Common Stock upon the
            exercise of the Rights among holders of Rights pursuant to this
            Section 11(a)(iii).

                  (b) In case the Company shall fix a record date for the
issuance of rights, options or warrants to all holders of Preferred Shares
entitling them (for a period expiring within 45 calendar days after such record
date) to subscribe for or purchase Preferred Shares (or shares having the same
rights, privileges and preferences as the Preferred Shares ("equivalent
preferred shares")) or securities convertible into Preferred Shares or
equivalent preferred shares at a price per Preferred Share or equivalent
preferred share (or having a conversion price per share, if a security
convertible into Preferred Shares or equivalent preferred shares) less than the
then current per share market price of the Preferred Shares (determined pursuant
to Section 11(d) hereof 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 number of Preferred Shares and equivalent preferred shares
which the aggregate offering price of the total number of Preferred Shares
and/or the total number of equivalent preferred shares 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 Preferred 

                                    -15-

<PAGE>


Shares and equivalent preferred shares to be offered for subscription or
purchase (or into which the convertible securities so to be offered are
initially convertible); 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
exercise of one Right. In case such subscription price may be paid in a
consideration part or all of which shall be in a form other than cash, the value
of such consideration shall be as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent. Preferred Shares and equivalent preferred shares
owned by or held for the account of the Company shall not be deemed outstanding
for the 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 the making
of a distribution to all holders of the Preferred Shares (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
or assets (other than a regular quarterly cash dividend or a dividend payable in
Preferred Shares) or subscription rights 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 then current per share market price of the Preferred Shares
(determined pursuant to Section 11(d) hereof) on such record date, less the fair
market value (as determined in good faith by the Board of the Company whose
determination shall be described in a statement filed with the Rights Agent) of
the portion of the assets or evidences of indebtedness so to be distributed or
of such subscription rights or warrants applicable to one Preferred Share, and
the denominator of which shall be such current per share market price
(determined pursuant to Section 11(d) hereof) of a Preferred Share; 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 to be issued upon exercise of one Right. 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 again be adjusted to
be the Purchase Price which would then be in effect if such record date had not
been fixed.

                  (d) (i) Except as otherwise provided herein, for the purpose
            of any computation hereunder, the "current per share market price"
            of any security (a "Security" for the purpose of this Section
            11(d)(i)) on any date shall be deemed to be the average of the daily
            closing prices per share of such Security for the 30 consecutive
            Trading Days (as such term is hereinafter defined) immediately prior
            to such date; provided, however, that in the event that the current
            per share market price of the Security is determined during a period
            following the announcement by the issuer of such Security of (A) a
            dividend or distribution on such Security payable in shares of such
            Security or securities convertible into such shares, or (B) any
            subdivision, combination 


                                    -16-

<PAGE>


            or reclassification of such Security, and prior to the expiration
            of 30 Trading Days after the ex-dividend date for such dividend
            or distribution, or the record date for such subdivision,
            combination or reclassification, then, and in each such case, the
            current per share market price shall be appropriately adjusted to
            reflect the current market price per share equivalent of such
            Security. The closing price for each day shall be the last sale
            price, regular way, or, in case no such sale takes place on such
            day, the average of the closing bid and asked prices, regular
            way, in either case as reported by the principal consolidated
            transaction reporting system with respect to securities listed or
            admitted to trading on the NASDAQ Stock Market or, if the
            Security is not listed or admitted to trading on the NASDAQ Stock
            Market, as reported in the principal consolidated transaction
            reporting system with respect to securities listed on the
            principal national securities exchange on which the Security is
            listed or admitted to trading or, if the Security is 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 National Association of Securities Dealers, Inc.
            Automated Quotations System ("NASDAQ") or such other system then
            in use, or, if on any such date the Security is 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 Security selected by the Board of Directors of the
            Company. The term "Trading Day" shall mean a day on which the
            principal national securities exchange on which the Security is
            listed or admitted to trading is open for the transaction of
            business or, if the Security is not listed or admitted to trading
            on any national securities exchange, a Business Day.

                         (ii) For the purpose of any computation hereunder, if
            the Preferred Shares are publicly traded, the "current per share
            market price" of the Preferred Shares shall be determined in
            accordance with the method set forth in Section 11(d)(i). If the
            Preferred Shares are not publicly traded but the Common Stock is
            publicly traded, the "current per share market price" of the
            Preferred Shares shall be conclusively deemed to be the current per
            share market price of the shares of Common Stock as determined
            pursuant to Section 11(d)(i) multiplied by one hundred
            (appropriately adjusted to reflect any stock split, stock dividend
            or similar transaction occurring after the date hereof). If neither
            the Common Stock nor the Preferred Shares are publicly traded,
            "current per share market price" shall mean the fair value per share
            as determined in good faith by the Board of Directors of 

                                    -17-

<PAGE>


            the Company, whose determination shall be described in a statement 
            filed with the Rights Agent.

                  (e) 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
ten-thousandth of a Preferred Share or share of Common Stock or other share or
security 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 requires 
such adjustment or (ii) the date of the expiration of the right to exercise any 
Rights.

                  (f) If as a result of an adjustment made pursuant to Section
11(a) hereof, the holder of any Right thereafter exercised shall become entitled
to receive any shares of capital stock of the Company other than Preferred
Shares, thereafter the number of such other shares so receivable upon exercise
of any Right 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 Shares contained in Sections 11(a)(i), 11(b), 11(c) and 11(i), and the
provisions of Sections 7, 9, 10 and 13 with respect to the Preferred Shares
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 one one-hundredths of a
Preferred Share purchasable 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
one one-hundredths of a Preferred Share (calculated to the nearest one
ten-thousandth of a Preferred Share) obtained by (i) multiplying (x) the number
of one one-hundredths of a share covered by a Right immediately prior to such
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 substitution
for any adjustment in the number of one one-hundredths of a Preferred Share
purchasable upon the exercise of a Right. Each of the Rights outstanding after
such adjustment of the number of Rights shall be exercisable for the number of
one one-hundredths of a Preferred Share 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- 

                                    -18-

<PAGE>


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 Right Certificates have
been issued, shall be at least 10 days later than the date of the public
announcement. If Right Certificates have been issued, upon each adjustment of
the number of Rights pursuant to this Section 11(i), the Company may, as
promptly as practicable, cause to be distributed to holders of record of Right
Certificates on such record date Right 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
Right Certificates held by such holders prior to the date of adjustment, and
upon surrender thereof, if required by the Company, new Right Certificates
evidencing all the Rights to which such holders shall be entitled after such
adjustment Right Certificates so to be distributed shall be issued, executed and
countersigned in the manner provided for herein and shall be registered in the
names of the holders of record of Right 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 one one-hundredths of a Preferred Share issuable upon the
exercise of the Rights, the Right Certificates theretofore and thereafter issued
may continue to express the Purchase Price and the number of one one-hundredths
of a Preferred Share which were expressed in the initial Right Certificates
issued hereunder.

                  (k) Before taking any action that would cause an adjustment
reducing the Purchase Price below the then par value, if any, of the Preferred
Shares or other shares of capital 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
fully paid and nonassessable Preferred Shares or other such shares at such
adjusted Purchase Price.

                  (l) 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 issuing to the holder of any Right exercised after such record date of
the Preferred Shares and other capital stock or securities of the Company, if
any, issuable upon such exercise over and above the Preferred Shares and 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 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 it in its sole discretion shall determine
to be advisable in order that any consolidation or subdivision of the Preferred

market price, issuance wholly for cash of Preferred Shares or securities which
by their terms are convertible into or exchangeable for Preferred Shares,
dividends on Preferred Shares payable in Preferred Shares or issuance of rights,
options or warrants referred to hereinabove in Section 11(b), hereafter made by
the Company to holders of its Preferred Shares shall not be taxable to such
stockholders.

                  (n) Anything in this Rights Agreement to the contrary
notwithstanding, in the event that at any time after the date of this Agreement
and prior to the Distribution Date, the Company shall (i) declare or pay any
dividend on the Common Shares payable in Common Shares or (ii) effect a
subdivision, combination or consolidation of the Common Shares (by 
reclassification or otherwise than by payment of dividends in Common Shares)
into a greater or lesser number of Common Shares, then in any such case, the
number of Rights associated with each Common Share then outstanding, or issued
or delivered thereafter shall be proportionately adjusted so that the number of
Rights thereafter associated with each Common Share following any such event
shall equal the result obtained by multiplying the number of Rights associated
with each Common Share immediately prior to such event by a fraction the
numerator of which shall be the total number of Common Shares outstanding
immediately prior to the occurrence of the event and the denominator of which
shall be the total number of Common Shares 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 13 hereof,
the Company shall promptly (a) prepare a certificate setting forth such
adjustment, and a brief statement of the facts accounting for such adjustment
and (b) file with the Rights Agent and with each transfer agent for the Common
Shares or the Preferred Shares a copy of such certificate. 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
EARNINGS POWER.

                  (a) In the event, directly or indirectly, at any time after
the Flip In Event, (i) the Company shall merge with and into any other Person,
(ii) any Person shall consolidate with the Company, or any Person shall merge
with and into the Company and the Company shall be the continuing or surviving
corporation of such merger and, in connection with such merger, all or part of
the Common Shares shall be changed into or exchanged for stock or other
securities of any other Person (or of the Company) or cash or any other
property, or (iii) the Company shall sell or otherwise transfer (or one or more
of its Subsidiaries shall sell or otherwise transfer), in one or more
transactions, assets or earnings power aggregating 50% or more of the assets or
earnings power of the Company and its Subsidiaries (taken as a whole) to any
other Person (other than the Company or one or more of its wholly-owned
Subsidiaries), then upon the first occurrence of such event, proper provision
shall be made so that: (A) each holder of record of a Right (other than Rights
which have become void pursuant to Section 11(a)(ii)) shall thereafter have the
right to receive, upon the exercise thereof at a price equal to the Purchase
Price immediately prior to the Flip In Event multiplied by the number of one
one-hundredths of a Preferred Share for which a Right was exercisable
immediately prior 

                                    -20-

<PAGE>



to such event, whether or not such Right was then exercisable (as subsequently
adjusted thereafter pursuant to Sections 11(a)(i), 11(b), 11(c) and 11(i)), in
accordance with the terms of this Agreement and in lieu of Preferred Shares,
such number of validly issued, fully-paid and non-assessable and freely
tradeable Common Shares of the Principal Party (as defined herein) not subject
to any liens, encumbrances, rights of first refusal or other adverse claims, as
shall be equal to the result obtained by (1) multiplying the Purchase Price
immediately prior to the Flip In Event by the number of one one-hundredths of a
Preferred Share for which a Right was exercisable immediately prior to such
event, whether or not such Right was then exercisable (as subsequently adjusted
thereafter pursuant to Sections 11(a)(i), 11(b), 11(c) and 11(i)), and (2)
dividing that product by 50% of the then current per share market price of the
Common Shares of such Principal Party (determined pursuant to Section 11(d)(i)
hereof) on the date of consummation of such consolidation, merger, sale or
transfer; provided that the Purchase Price and the number of Common Shares of
such Principal Party issuable upon exercise of each Right shall be further
adjusted as provided in Section 11(f) of this Rights Agreement to reflect any
events occurring in respect of such Principal Party after the date of such
consolidation, merger, sale or transfer; (B) such Principal Party shall
thereafter be liable for, and shall assume, by virtue of such consolidation,
merger, sale or transfer, all the obligations and duties of the Company pursuant
to this Rights Agreement; (C) the term "Company" shall thereafter be deemed to
refer to such Principal Party; and (D) such Principal Party shall take such
steps (including, but not limited to, the reservation of a sufficient number of
its shares of Common Stock in accordance with Section 9 hereof) in connection
with such consummation of any such transaction as may be necessary to assure
that the provisions hereof shall thereafter be applicable, as nearly as
reasonably may be, in relation to the shares of Common Stock thereafter
deliverable upon the exercise of the Rights; provided that, upon the subsequent
occurrence of any consolidation, merger, sale or transfer of assets 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 as provided in this Section 13(a), such cash,
shares, rights, warrants and other property which such holder would have been
entitled to receive had such holder, at the time of such transaction, owned the
Common Shares of the Principal Party purchasable upon the exercise of a Right
pursuant to this Section 13(a), 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.

                  (b)   "Principal Party" shall mean

                          (i) in the case of any transaction described in (i) or
            (ii) of the first sentence of Section 13(a) hereof, (A) the Person
            that is the issuer of the securities into which Common Shares are
            converted in such merger or consolidation, or, if there is more than
            one such issuer, the issuer the Common Shares of which has the
            greatest aggregate market value of shares outstanding or (B) if no
            securities are so issued, (x) the Person that is the other party to
            the merger, if such Person survives said merger, or, if there is
            more than one such Person, the Person the Common Shares of which has
            the greatest aggregate market value of shares outstanding or (y) if
            the Person that is the other party to the 



                                    -21-

<PAGE>

            merger does not survive the merger, the Person that does survive
            the merger (including the Company if it survives) or (z) the
            Person resulting from the consolidation; and

                         (ii) in the case of any transaction described in (iii)
            of the first sentence in Section 13(a) hereof, the Person that is
            the party receiving the greatest 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 so
            transferred or if the Person receiving the greatest portion of the
            assets or earning power cannot be determined, whichever of such
            Persons as is the issuer of Common Shares having the greatest
            aggregate market value of shares outstanding;

provided, however, that in any such case described in the foregoing clause
(b)(i) or (b)(ii), (1) if the Common Shares of such Person are not at such time
or have not been continuously over the preceding 12-month period registered
under Section 12 of the Exchange Act, and if such Person is a direct or indirect
Subsidiary of another Person the Common Shares of which are and have been so
registered, the term "Principal Party" shall refer to such other Person, or (2)
if such Person is a Subsidiary, directly or indirectly, of more than one Person,
the Common Shares of all of which are and have been so registered, the term
"Principal Party" shall refer to whichever of such Persons is the issuer of the
Common Shares having the greatest aggregate market value of shares outstanding,
or (3) if such Person is owned, directly or indirectly, by a joint venture
formed by two or more Persons that are not owned, directly or indirectly, by the
same Person, the rules set forth in clauses (1) and (2) above shall apply to
each of the owners having an interest in the venture as if the Person owned by
the joint venture was a Subsidiary of both or all of such joint venturers, and
the Principal Party in each such case shall bear the obligations set forth in
this Section 13 in the same ratio as its interest in such Person bears to the
total of such interests.

                  (c) The Company shall not consummate any consolidation,
merger, sale or transfer referred to in Section 13(a) hereof unless prior
thereto the Company and the Principal Party involved therein shall have executed
and delivered to the Rights Agent an agreement confirming that the requirements
of Sections 13(a) and (b) hereof shall promptly be performed in accordance with
their terms and that such consolidation, merger, sale or transfer of assets
shall not result in a default by the Principal Party under this Rights Agreement
as the same shall have been assumed by the Principal Party pursuant to Sections
13(a) and (b) hereof and providing that, as soon as practicable after executing
such agreement pursuant to this Section 13, the Principal Party will:

                          (i) prepare and file a registration statement under
            the Securities Act, if necessary, with respect to the Rights and the
            securities purchasable upon exercise of the Rights on an appropriate
            form, use its best efforts to cause such registration statement to
            become effective as soon as practicable after such filing and use
            its best efforts to cause such registration statement 


                                    -22-

<PAGE>

            to remain effective (with a prospectus at all times meeting the 
            requirements of the Securities Act) until the Expiration Date, and 
            similarly comply with applicable state securities laws;

                         (ii) use its best efforts, if the Common Shares of the
            Principal Party shall be listed or admitted to trading on the NASDAQ
            Stock Market or on a national securities exchange, to list or admit
            to trading (or continue the listing of) the Rights and the
            securities purchasable upon exercise of the Rights on the NASDAQ
            Stock Market or such securities exchange and, if the Common Shares
            of the Principal Party shall not be listed or admitted to trading on
            the NASDAQ Stock Market or a national securities exchange, to cause
            the Rights and the securities purchasable upon exercise of the
            Rights to be reported by such other system then in use;

                        (iii) deliver to holders of the Rights historical
            financial statements for the Principal Party which comply in all
            respects with the requirements for registration on Form 10 (or any
            successor form) under the Exchange Act; and

                         (iv) obtain waivers of any rights of first refusal or
            preemptive rights in respect of the Common Shares of the Principal
            Party subject to purchase upon exercise of outstanding Rights.

                  (d) Furthermore, in case the Principal Party which is to be a
party to a transaction referred to in this Section 13 has 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 (other than to holders of
Rights pursuant to this Section 13), in connection with, or as a consequence of,
the consummation of a transaction referred to in this Section 13, Common Shares
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 Shares of such Principal Party at less than such then
current market price, or (ii) providing for any special payment, tax or similar
provisions in connection with the issuance of the Common Shares of such
Principal Party pursuant to the provisions of Section 13, then, in such event,
the Company hereby agrees with each holder of Rights that it 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 canceled, 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 Company covenants and agrees that it shall not, at any
time after the Flip In Event, enter into any transaction of the type
contemplated by (i)-(iii) of Section 13(a) hereof if (x) at the time of or
immediately after such consolidation, merger, sale, 


                                    -23-

<PAGE>



transfer or other transaction 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, (y) prior to, simultaneously with or immediately after
such consolidation, merger, sale, transfer of other transaction, the
stockholders of the Person who constitutes, or would constitute, the "Principal
Party" for purposes of Section 13(a) hereof shall have received a distribution
of Rights previously owned by such Person or any of its Affiliates or Associates
or (z) the form or nature of organization of the Principal Party would preclude
or limit the exercisability of the Rights.

            Section 14. FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

                  (a) The Company shall not be required to issue fractions of
Rights or to distribute Right Certificates which evidence fractional Rights. In
lieu of such fractional Rights, there shall be paid to the registered holders of
the Right Certificates with regard to which such fractional Rights would
otherwise be issuable, an amount in cash equal to the same fraction of the
current market value of a whole Right. For the purposes of this Section 14(a),
the current 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 for any
day shall be the last sale price, regular way, or, in case no such sale takes
place on such day, the average of the closing bid and asked prices, regular way,
in either case as reported in the principal consolidated transaction reporting
system with respect to securities listed or admitted to trading on the NASDAQ
Stock Market or, if the Rights are not listed or admitted to trading on the
NASDAQ Stock Market, 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 the Board of Directors of the Company. 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 the Board of Directors of the Company
shall be used.

                  (b) The Company shall not be required to issue fractions of
Preferred Shares (other than fractions which are integral multiples of one
one-hundredth of a Preferred Share) upon exercise of the Rights or to distribute
certificates which evidence fractional Preferred Shares (other than fractions
which are integral multiples of one one-hundredth of a Preferred Share).
Interests in fractions of Preferred Shares in integral multiples of one
one-hundredth of a Preferred Share may, at the election of the Company, be
evidenced by depositary receipts, pursuant to an appropriate agreement between
the Company and a depositary selected by it; provided, that such agreement shall
provide that the holders of such depositary receipts shall have all the rights,
privileges and preferences to which they are entitled as beneficial owners of
the Preferred Shares represented by such depositary receipts. In lieu of
fractional Preferred Shares that are not integral multiples of one one-hundredth
of a Preferred Share, the Company shall pay to the registered holders of Right
Certificates at the time such Rights are exercised as herein provided an amount
in cash equal to the same fraction of the current market 

                                    -24-

<PAGE>

value of one Preferred Share. For the purposes of this Section 14(b), the
current market value of a Preferred Share shall be the closing price of a
Preferred Share (as determined pursuant to Section 11(d)(i) hereof) for the
Trading Day immediately prior to the date of such exercise.

                  (c) The holder of a Right by the acceptance of the Right
expressly waives his right to receive any fractional Rights or any fractional
shares upon exercise of a Right (except as provided above).

            Section 15. RIGHTS OF ACTION. All rights of action in respect of
this Agreement, excepting the rights of action given to the Rights Agent under
Section 18 hereof, are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares); and any registered holder of any Right Certificate (or, prior to
the Distribution Date, of the Common Shares), without the consent of the Rights
Agent or of the holder of any other Right Certificate (or, prior to the
Distribution Date, of the Common Shares), on his own behalf and for his own
benefit, may enforce, and may institute and maintain any suit, action or
proceeding against the Company to enforce, or otherwise act in respect of, his
right to exercise the Rights evidenced by such Right Certificate in the manner
provided in such Right 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 will be entitled to specific performance of
the obligations under, and injunctive relief against actual or threatened
violations of, the obligations of any Person subject to this Agreement.

            Section 16. AGREEMENT OF RIGHT HOLDERS. Every holder of a Right, by
accepting the same, consents and agrees with the Company and the Rights Agent
and with every holder of a Right that:

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

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

                  (c) the Company and the Rights Agent may deem and treat the
Person in whose name the Right Certificate (or, prior to the Distribution Date,
the associated Common Shares certificate) is registered as the absolute owner
thereof and of the Rights evidenced thereby (notwithstanding any notations of
ownership or writing on the Right Certificates or the associated Common Shares
certificate made by anyone other than the Company or the Rights Agent) for all
purposes whatsoever, and neither the Company nor the Rights Agent shall be
affected by any notice to the contrary.

            Section 17. RIGHT CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER. No
holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the Preferred Shares 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 

                                    -25-

<PAGE>


contained herein or in any Right Certificate be construed to confer upon the
holder of any Right 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 to receive notice of meetings or other
actions affecting stockholders (except as provided in this Agreement), or to
receive dividends or subscription rights, or otherwise, until the Rights
evidenced by such Right Certificate shall have been exercised in accordance with
the provisions hereof.

            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 and counsel fees and
other disbursements incurred in the administration and execution of this
Agreement and the exercise and performance of its duties hereunder. The Company
also agrees to indemnify the Rights Agent for, and to 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 costs and expenses of defending against any claim of
liability arising therefrom, directly or indirectly.

                  (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 Agreement in reliance upon any Right
Certificate or certificate for the Preferred Shares, Common Shares 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 be signed, executed and where necessary, verified or acknowledged, by the
proper Person or Persons, or otherwise upon the advice of counsel as set forth
in Section 20 hereof.

            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 stock transfer or corporate trust powers 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 paper or any further act
on the part of any of the parties hereto; provided, 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 Right Certificates shall
have been countersigned but not delivered, any such successor Rights Agent may
adopt the countersignature of the predecessor Rights Agent and deliver such
Right Certificates so countersigned; and in case at that time any of the Right
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Right Certificates either in the name of the predecessor Rights
Agent or in the name of the successor Rights Agent; and in all such cases such
Right Certificates shall have the full force provided in the Right Certificates
and in this Agreement.



                                    -26-

<PAGE>



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

                  (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 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 herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by any one of the Chairman of the Board of
Directors, the President, any Vice President, the Treasurer, the Controller or
the Secretary of the Company and delivered to the Rights Agent; 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 to the Company
and any other Person only for its own negligence, bad faith or wilful
misconduct.

                  (d) The Rights Agent shall not be liable for or by reason of
any of the statements of facts or recitals contained in this Agreement or in the
Right Certificates (except its countersignature thereof) or be required to
verify the same, 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 be under any responsibility in
respect of the validity of this Agreement or the execution and delivery hereof
(except the due execution hereof by the Rights Agent) or in respect of the
validity or execution of any Right Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Agreement or in any Right Certificate;
nor shall it be responsible for any change in the exercisability of the Rights
(including the Rights becoming void pursuant to Section 11(a)(ii) hereof) or any
adjustment in the terms of the Rights (including the manner, method or amount
thereof) provided for in Sections 3, 11, 13, 23 and 24, or the ascertaining of
the existence of facts that would require any such change or adjustment (except
with respect to the exercise of Rights evidenced by Right Certificates after
receipt of a certificate furnished pursuant to Section 12, describing such
change or adjustment); nor shall it

                                    -27-

<PAGE>



by any act hereunder be deemed to make any representation or warranty as to the
authorization or reservation of any Preferred Shares to be issued pursuant to
this Agreement or any Right Certificate or as to whether any Preferred Shares
will, when issued, be validly authorized and issued, fully paid and
nonassessable.

                  (f) The Company agrees that it will perform, execute,
acknowledge and deliver or cause to be performed, executed, acknowledged and
delivered all such further and other acts, instruments and assurances as may
reasonably be required by the Rights Agent for the carrying out or performing by
the Rights Agent of the provisions of this Agreement.

                  (g) The Rights Agent is hereby authorized and directed to
accept instructions with respect to the performance of its duties hereunder from
any person reasonably believed by the Rights Agent to be one of the Chairman of
the Board of Directors, the President, any Vice President, the Secretary, the
Controller or the 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 by it in good faith in accordance with
instructions of any such officer or for any delay in acting while waiting for
those instructions. 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 officer of the Company actually received 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 stockholder, 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 become pecuniarily interested in any transaction in
which the Company may be interested, or contract with or lend money to the
Company. 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, and the Rights Agent shall not be
answerable or accountable for any act, default, neglect or misconduct of any
such attorneys or agents or for any loss to the Company resulting from any such
act, default, neglect or misconduct, provided reasonable care was exercised in
the selection and continued employment thereof.

                  (j) If, with respect to any Rights Certificate surrendered to
the Right Agent for exercise or transfer, the certificate contained in the form
of assignment or the form of election to purchase set forth on the reverse
thereof, as the case may be, has not been completed to certify the holder is not
an Acquiring Person (or an Affiliate or Associate thereof), 


                                    -28-

<PAGE>


the Rights Agent shall not take any further action with respect to such
requested exercise of transfer without first consulting with the Company.

            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 30 days' prior notice in writing mailed to the Company and to
each transfer agent of the Common Shares or Preferred Shares by registered or
certified mail, and to the holders of the Right Certificates by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
30 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 Common Shares or
Preferred Shares by registered or certified mail, and to the holders of the
Right 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 30 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 Right Certificate
(who shall, with such notice, submit his Right Certificate for inspection by the
Company), then the registered holder of any Right 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 corporation organized and doing business under the laws of the United
States or the State of New York (or of any other state of the United States so
long as such corporation is authorized to do business as a banking institution
in the State of New York), in good standing, having an office in the State of
New York, 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. 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 Common Shares or Preferred Shares, 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, as the case may be.

            Section 22. ISSUANCE OF NEW RIGHT CERTIFICATES. Notwithstanding any
of the provisions of this Agreement or of the Rights to the contrary, the
Company may, at its option, issue new Right Certificates evidencing Rights in
such forms as may be approved by its Board of Directors to reflect any
adjustment or change in the Purchase Price and the number or kind or class of
shares or other securities or property purchasable under the Rights Certificates
made in accordance with the provisions of this Agreement. In addition, in
connection with the issuance or sale of Common Shares following the Distribution
Date and prior to the earlier of the Redemption Date and the Expiration Date,
the Company may with respect to Common Shares so issued or sold pursuant to (i)
the exercise of stock options, (ii) under any employee plan or arrangement,
(iii) upon the exercise, conversion or exchange of securities, notes or
debentures issued by the Company or (iv) a contractual obligation of the
Company, in each case 

                                    -29-

<PAGE>

existing prior to the Distribution Date, issue Rights Certificates representing
the appropriate number of Rights in connection with such issuance or sale.

            Section 23. REDEMPTION.

                  (a) The Board of Directors of the Company may, at any time
prior to the Flip In Event, redeem all but not less than all the then
outstanding Rights at a redemption price of $.001 per Right, appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof (the redemption price being hereinafter referred
to as the "Redemption Price"). The redemption of the Rights 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 the Board of Directors
ordering the redemption of the Rights pursuant to paragraph (a) of this Section
23 (or at such later time as the Board of Directors may establish for the
effectiveness of such redemption), 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.
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. Within 10 days after such action of the
Board of Directors ordering the redemption of the Rights, the Company shall mail
a notice of redemption to all the holders of the then outstanding Rights at
their last addresses as they appear upon the registry books of the Rights Agent
or, prior to the Distribution Date, on the registry books of each transfer agent
for the Common Shares. 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 shall state the method by which the payment of the
Redemption Price will be made.

            Section 24. EXCHANGE.

                  (a) The Board of Directors of the Company may, at its option,
at any time after the Flip In Event, exchange all or part of the then
outstanding and exercisable Rights (which shall not include Rights that have
become void pursuant to the provisions of Section 11(a)(ii) hereof) for shares
of Common Stock at an exchange ratio of one share of Common Stock per Right,
(such exchange ratio being hereinafter referred to as 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 Common Shares aggregating 50% or more of the Common Shares
then outstanding.

                  (b) Immediately upon the action of the Board of Directors of
the Company ordering the exchange of any Rights pursuant to paragraph (a) of
this Section 24 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 shares of Common Stock
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 


                                    -30-

<PAGE>



validity of such exchange. The Company shall promptly mail a notice of any such
exchange to all of the holders of the Rights so exchanged at their last
addresses as they appear upon the registry books of the Rights Agent. Any notice
which is mailed in the manner herein providedshall be deemed given, whether or
not the holder receives the notice. Each such notice of exchange will state the
method by which the exchange of the shares of Common Stock 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 11(a)(ii) hereof) held by each holder of Rights.

                  (c) In the event that there shall not be sufficient shares of
Common Stock issued but not outstanding or authorized but unissued to permit any
exchange of Rights as contemplated in accordance with this Section 24, the
Company may, in its discretion, take such action as may be necessary to
authorize additional shares of Common Stock for issuance upon exchange of the
Rights. In the event that the Company shall determine not to take such action or
shall, after good faith effort, be unable to take such action as may be
necessary to authorize such additional shares of Common Stock, the Company shall
substitute, to the extent of such insufficiency, for each share of Common Stock
that would otherwise be issuable upon exchange of a Right, a number of Preferred
Shares or fractions thereof (or equivalent preferred shares as such term is
defined in Section 11(b)), having an aggregate value equal to the current per
share market price of one share of Common Stock (determined pursuant to Section
11(d) hereof) as of the date of issuance of such Preferred Shares or fractions
thereof (or equivalent preferred shares).

                  (d) The Company shall not, in connection with any exchange
pursuant to this Section 24, be required to issue fractions of shares of Common
Stock or to distribute certificates which evidence fractional shares of Common
Stock. In lieu of such fractional shares of Common Stock, the Company shall pay
to the registered holders of the Right Certificates with regard to which such
fractional shares of Common Stock would otherwise be issuable an amount in cash
equal to the same fraction of the current market value of a whole share of
Common Stock. For the purposes of this paragraph (d), the current market value
of a whole share of Common Stock shall be the closing price of a share of Common
Stock (as determined pursuant to the second sentence of Section 11(d)(i) hereof)
for the Trading Day immediately prior to the date of exchange pursuant to this
Section 24.

            Section 25. NOTICE OF CERTAIN EVENTS.

                  (a) In case the Company shall at any time after the earlier of
the Distribution Date or the Shares Acquisition Date propose (i) to pay any
dividend payable in stock of any class to the holders of its Preferred Shares or
to make any other distribution to the holder of its Preferred Shares (other than
a regular quarterly cash dividend), (ii) to offer to the holders of its
Preferred Shares rights or warrants to subscribe for or to purchase any
additional Preferred Shares or shares of stock of any class or any other
securities, rights or options, (iii) to effect any reclassification of its
Preferred Shares (other than a reclassification involving only the subdivision
of outstanding Preferred Shares), (iv) to effect the liquidation, dissolution or
winding up of the Company, or (v) to declare or pay any dividend on the Common
Shares payable in Common Shares or to effect a subdivision, combination or
consolidation of the Common Shares 


                                    -31-

<PAGE>



(by reclassification or otherwise than by payment of dividends in Common Shares)
then, in each such case, the Company shall give to each holder of a Right
Certificate, in accordance with Section 26 hereof, a notice of such proposed
action, which shall specify the record date for the purposes of such stock
dividend, or distribution of rights or warrants, or the date on which such
liquidation, dissolution or winding up is to take place and the date of
participation therein by the holders of the Common Shares and/or Preferred
Shares, 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 10 days
prior to the record date for determining holders of the Preferred Shares for
purposes of such action, and in the case of any such other action, at least 10
days prior to the date of the taking of such proposed action or the date of
participation therein by the holders of the Common Shares and/or Preferred
Shares, whichever shall be the earlier.

                  (b) In case any event described in Section 11(a)(ii) or
Section 13 shall occur then the Company shall as soon as practicable thereafter
give to each holder of a Right Certificate (or if occurring prior to the
Distribution Date, the holders of Common Shares) in accordance with Section 26
hereof, a notice of the occurrence of such event, which notice shall describe
such event and the consequences of such event to holders of Rights under Section
11(a)(ii) and Section 13 hereof.

            Section 26. NOTICES. Notices or demands authorized by this Agreement
to be given or made by the Rights Agent or by the holder of any Right
Certificate to or on the Company shall be sufficiently given or made if sent by

                  Attention: Gregory D. Tubbs

books of the Company.

            Section 27. SUPPLEMENTS AND AMENDMENTS. Except as provided in the
penultimate sentence of this Section 27, for so long as the Rights are then
redeemable, the Company may in its sole and absolute discretion, and the Rights
Agent shall if the Company so 

                                    -32-

<PAGE>



directs, supplement or amend any provision of this Rights Agreement in any
respect without the approval of any holders of the Rights. At any time when the
Rights are no longer redeemable, except as provided in the penultimate sentence
of this Section 27, the Company may, and the Rights Agent shall, if the Company
so directs, supplement or amend this Rights Agreement without the approval of
any holders of Rights Certificates in order to (i) cure any ambiguity, (ii)
correct or supplement any provision contained herein which may be defective or
inconsistent with any other provisions herein, (iii) shorten or lengthen any
time period hereunder, or (iv) change or supplement the provisions hereunder in
any manner which the Company may deem necessary or desirable; provided that no
such supplement or amendment shall adversely affect the interests of the holders
of Rights as such (other than an Acquiring Person or an Affiliate or Associate
of an Acquiring Person), and no such amendment may cause the rights again to
become redeemable or cause the Agreement again to become amendable other than in
accordance with this sentence. Notwithstanding anything contained in this Rights
Agreement to the contrary, no supplement or amendment shall be made which
changes the Redemption Price. Upon the delivery of a certificate from an
appropriate officer of the Company which states that the proposed supplement or
amendment is in compliance with the terms of this Section 27, the Rights Agent
shall execute such supplement or amendment.

            Section 28. 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.

            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 Right Certificates (and, prior to the
Distribution Date, the Common Shares) 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 Right Certificates (and, prior to the Distribution Date, the Common Shares).

            Section 30. SEVERABILITY. If any term, provision, covenant or
restriction of this Agreement or applicable to 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.

            Section 31. GOVERNING LAW. This Agreement and each Right Certificate
issued hereunder shall be deemed to be a contract made under the laws of the
State of Delaware and for all purposes shall be governed by and construed in
accordance with the laws of such State applicable to contracts to be made and
performed entirely within such State.

            Section 32. COUNTERPARTS.  This Agreement may be executed in any
number of counterparts and each of such counterparts shall for all purposes be
deemed to be an original, and all such counterparts shall together constitute
but one and the same instrument.

            Section 33. DESCRIPTIVE HEADINGS.  Descriptive headings of the
several Sections of this Agreement are inserted for convenience only and shall

                        (Pursuant to Section 151 of the
                       Delaware General Corporation Law)

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


          Rock Bottom Restaurants, Inc., a corporation organized and existing
under the General Corporation Law of the State of Delaware (hereinafter called
the "Company"), hereby certifies that the following resolution was adopted by
the Board of Directors of the Company as required by Section 151 of the General
Corporation Law at a meeting duly called and held on December 12, 1997:

          RESOLVED, that pursuant to the authority granted to and vested in the
Board of Directors of the Company (hereinafter called the "Board of Directors"
or the "Board") in accordance with the provisions of the Certificate of
Incorporation, as amended to date (hereinafter called the "Certificate of
Incorporation"), the Board of Directors hereby creates a series of preferred
stock, par value $.01 per share, of the Company and hereby states the
designation and number of shares, and fixes the relative rights, preferences,
and limitations thereof as follows:

            Section 1. DESIGNATION AND AMOUNT. The shares of such series shall
be designated as "Series A Junior Participating Preferred Stock" (the "Series A
Preferred Stock") and the number of shares constituting the Series A Preferred
Stock shall be 300,000. Such number of shares may be increased or decreased by
resolution of the Board of Directors; provided, that no decrease shall reduce
the number of shares of Series A Preferred Stock to a number less than the
number of shares then outstanding plus the number of shares reserved for
issuance upon the exercise of outstanding options, rights or warrants or upon
the conversion of any outstanding securities issued by the Company convertible
into Series A Preferred Stock.



                                    A-1

<PAGE>




            Section 2.  DIVIDENDS AND DISTRIBUTIONS.

            (A) Subject to the rights of the holders of any shares of any series
of preferred stock of the Company (the "Preferred Stock") (or any similar stock)
ranking prior and superior to the Series A Preferred Stock with respect to
dividends, the holders of shares of Series A Preferred Stock, in preference to
the holders of Common Stock, par value $.01 per share of the Company (the
"Common Stock"), and of any other stock of the Company ranking junior to the
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 the purpose,
semi-annual dividends payable in cash on the first day of June and December in
each year (each such date being referred to herein as a "Dividend Payment
Date"), commencing on the first Dividend Payment Date after the first issuance
of a share or fraction of a share of Series A Preferred Stock, in an amount per
share (rounded to the nearest cent) equal to the greater of (a) $1 or (b)
subject to the provision for adjustment hereinafter set forth, 100 times the
aggregate per share amount of all cash dividends, and 100 times the aggregate
per share amount (payable in kind) of all non-cash dividends or other
distributions other than a dividend payable in shares of Common Stock, declared
on the Common Stock since the immediately preceding Dividend Payment Date or,
with respect to the first Dividend Payment Date, since the first issuance of any
share or fraction of a share of Series A Preferred Stock. In the event the
Company shall at any time declare or pay any dividend on the Common Stock
payable in shares of Common Stock, or effect a subdivision or combination or
consolidation of the outstanding shares of Common Stock (by the classification
or otherwise than by payment of a dividend in shares of Common Stock) into a
greater or lesser number of shares of Common Stock, then in each such case the
amount to which holders of shares of Series A Preferred Stock were 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 is
the number of shares of Common Stock outstanding immediately after such event
and the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

            (B) The Company shall declare a dividend or distribution on the
Series A Preferred Stock as provided in paragraph (A) of this Section
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock); provided that, in the
event no dividend or distribution shall have been declared on the Common Stock
during the period between any Dividend Payment Date and the next subsequent
Dividend Payment Date, a dividend of $1 per share on the Series A Preferred
Stock shall nevertheless be payable on such subsequent Dividend Payment Date.

            (C) Dividends shall begin to accrue and be cumulative on outstanding
shares of Series A Preferred Stock from the Dividend Payment Date next preceding
the date of issue of such shares, unless the date of issue of such shares is
prior to the record date for the first Dividend Payment Date, in which case
dividends on such shares shall begin to accrue from the date of issue of such
shares, or unless the date of issue is a Dividend Payment Date or is a date
after the record date for the determination of holders of shares of Series A
Preferred Stock entitled to receive a quarterly dividend and before such
Dividend Payment Date, in either of which events such dividends shall begin to
accrue and be cumulative from such Dividend


                                    A-2

<PAGE>



Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends
paid on the shares of Series A Preferred Stock in an amount less than the total
amount of such dividends at the time accrued and payable on such shares shall be
allocated pro rata on a share-by-share basis among all such shares at the time
outstanding. The Board of Directors may fix a record date for the determination
of holders of shares of Series A Preferred Stock entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be not more
than 60 days prior to the date fixed for the payment thereof.

            Section 3.  VOTING RIGHTS.  The holders of shares of Series A
Preferred Stock shall have the following voting rights:

            (A) Subject to the provision for adjustment hereinafter set forth
and except as otherwise provided in the Certificate of Incorporation or required
by law, each share of Series A Preferred Stock shall entitle the holder thereof
to 100 votes on all matters upon which the holders of the Company are entitled
to vote. In the event the Company shall at any time declare or pay any dividend
on the Common Stock payable in shares of Common Stock, or effect a subdivision
or combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the number of votes per share to which holders of shares 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 is the number
of shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

            (B) Except as otherwise provided herein, in the Certificate of
Incorporation or in any other Certificate of Designations creating a series of
Preferred Stock or any similar stock, and except as otherwise required by law,
the holders of shares of Series A Preferred Stock and the holders of shares of

                          (i) declare or pay dividends, or make any other

                         (ii) declare or pay dividends, or make any other

            ratably on the Series A Preferred Stock and all such parity stock on
            which dividends are payable or in arrears in proportion to the total
            amounts to which the holders of all such shares are then entitled;

                        (iii) redeem or purchase or otherwise acquire for
            consideration shares of any stock ranking junior (either as to
            dividends or upon liquidation, dissolution or winding up) to the
            Series A Preferred Stock, provided that the Company may at any time
            redeem, purchase or otherwise acquire shares of any such junior
            stock in exchange for shares of any stock of the Company ranking
            junior (as to dividends and upon dissolution, liquidation or winding
            up) to the Series A Preferred Stock;

                         (iv) redeem or purchase or otherwise acquire for
            consideration any shares of Series A Preferred Stock, or any shares
            of stock ranking on a parity (either as to dividends or upon
            liquidation, dissolution (either as to dividends or upon
            liquidation, dissolution or winding up) with the 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 shares upon such terms as the Board of Directors,
            after consideration of the respective annual dividend rates and
            other relative rights and preferences of the respective series and
            classes, shall determine in good faith will result in fair and
            equitable treatment among the respective series or classes.

            (B) The Company shall not permit any subsidiary of the Company to

liquidation, dissolution or winding up to the Series A Preferred Stock unless,
prior thereto, the holders of shares of Series A Preferred Stock shall have
received $100 per share, plus an amount equal to accrued and unpaid dividends
and distributions thereon, to the date of such payment, provided that the
holders of shares of Series A Preferred Stock shall be entitled to receive an
aggregate amount per share, subject to the provision for adjustment hereinafter
set forth, equal to 100 times the aggregate amount to be distributed per share
to holders of shares of Common Stock, or (B) to the holders of shares of stock
ranking on a parity upon liquidation, dissolution or winding up with the Series
A Preferred Stock, except distributions made ratably on the Series A Preferred
Stock and all such parity stock in proportion to the total amounts to which the
holders of all such shares are entitled upon such liquidation, dissolution or
winding up. In the event the Company shall at any time declare or pay any
dividend on the Common Stock (by reclassification or otherwise than by payment
of a dividend in shares of Common Stock) into a greater or lesser number of
shares of Common Stock, then in each such case the aggregate amount to which
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event under the proviso in clause (A) of the preceding sentence shall be
adjusted by multiplying such amount by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

            Section 7. CONSOLIDATION, MERGER, ETC. In case the Company shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Series A Preferred Stock shall at the same time be similarly exchanged or
changed into an amount per share (subject to the provision for adjustment
hereinafter set forth) equal to 100 times 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 changed or exchanged.
In the event the Company shall at any time declare or pay any dividend on the
Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series A Preferred Stock shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

            Section 8.  NO REDEMPTION.  The shares of Series A Preferred Stock
shall not be redeemable from any holder.

            Section 9. RANK. The Series A Preferred Stock shall rank, with
respect to the payment of dividends and the distribution of assets upon
liquidation, dissolution or winding up of the Company, junior to all series of
any other class of Preferred Stock and senior to the Common Stock.

then the holders of the Series A Preferred Stock shall be entitled to vote
separately as a class upon such amendment, and the affirmative vote of
two-thirds of the outstanding shares of the Series A Preferred Stock, voting

upon surrender at the office or agency of the Rights Agent designated for such
purpose, may be exchanged for another Right Certificate or Right Certificates of
like tenor and date evidencing Rights entitling the holder to purchase a like
aggregate number of Preferred Shares as the Rights evidenced by the Right
Certificate or Right Certificates surrendered shall have entitled such holder to

be entitled to receive upon surrender hereof another Right Certificate or Right
Certificates for the number of whole Rights not exercised.

            Subject to the provisions of the Rights Agreement, the Rights

vote or receive dividends or be deemed for any purpose the holder of the
Preferred Shares or of any other securities of the Company which may at any time
be issuable on the exercise hereof, nor shall anything contained in the Rights

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 or subscription
rights, or otherwise, until the Right or Rights evidenced by this Right
certificate shall have been exercised as provided in the Rights Agreement. This
Right Certificate shall not be valid or obligatory for any purpose until it
