     5. OTHER EVENTS.

     On July 22, 1999, the Board of Directors of Tehama Bancorp (the "Company"),
declared a dividend payable on August 31, 1999 of one right (a "Right") for each
outstanding share of common stock, without par value ("Common Stock"), of the
Company held of record at the close of business on August 2, 1999 (the "Record
Time"), or issued thereafter and prior to the Separation Time (as hereinafter
defined) and thereafter pursuant to options and convertible securities
outstanding at the Separation Time. The Rights will be issued pursuant to a
Shareholder Protection Rights Agreement, dated as of July 23, 1999 (the "Rights
Agreement"), between the Company and U. S. Stock Transfer Corporation, as Rights
Agent (the "Rights Agent"). Each Right entitles its registered holder to
purchase from the Company, after the Separation Time, one one-hundredth of a
share of Participating Preferred Stock, without par value ("Participating
Preferred Stock"), for $55.00 (the "Exercise Price"), subject to adjustment.

     The Rights will be evidenced by the Common Stock certificates until the
close of business on the earlier of (either, the "Separation Time") (i) the
tenth business day (or such later date as the Board of Directors of the Company
may from time to time fix by resolution adopted prior to the Separation Time
that would otherwise have occurred) after the date on which any Person (as
defined in the Rights Agreement) commences a tender or exchange offer which, if
consummated, would result in such Person's becoming an Acquiring Person, as
defined below, and (ii) the tenth business day after the first date (the
"Flip-in Date") of public announcement by the Company or any Person that such
Person has become an Acquiring Person, other than as a result of a Flip-over
Transaction or Event (as defined below); provided, that if the foregoing results
in the Separation Time being prior to the Record Time, the Separation Time shall
be the Record Time; and provided further that if a tender or exchange offer
referred to in clause (i) is cancelled, terminated or otherwise withdrawn prior
to the Separation Time without the purchase of any shares of stock pursuant
thereto, such offer shall be deemed never to have been made.

     An Acquiring Person is any Person having Beneficial Ownership (as defined
in the Rights Agreement) of 10% or more of the outstanding shares of Common
Stock, which term shall not include (i) the Company, any wholly-owned subsidiary
of the Company, or any employee stock ownership or other employee benefit plan
of the Company or of any wholly-owned subsidiary of the Company; (ii) any person
who is the Beneficial Owner of 10% or more of the outstanding Common Stock as of
the date of the Rights Agreement or who shall become the Beneficial Owner of 10%
or more of the outstanding Common Stock solely as a result of an acquisition of
Common Stock by the Company, until such time as such Person acquires additional
Common Stock, other than through a dividend or stock split; (iii) any Person who
becomes an Acquiring Person without any plan or intent to seek or affect control
of the Company if such Person, upon notice by the Company, promptly divests
sufficient securities such that such 10% or greater Beneficial Ownership ceases;
or (iv) any Person who Beneficially Owns shares of Common Stock consisting
solely of (A) shares acquired pursuant to the grant or exercise of an option
granted by the Company in connection with an agreement to merge with, or
acquire, the Company at a time at which there is no Acquiring Person, (B) shares
owned by such Person and its Affiliates (as defined in the Rights Agreement) and
Associates (as defined in the


                                       -2-

<PAGE>

Rights Agreement) at the time of such grant and (C) shares, amounting to less
than 1% of the outstanding Common Stock, acquired by Affiliates and Associates
of such Person after the time of such grant.

     The Rights Agreement provides that, until the Separation Time, the Rights
will be transferred with and only with the Common Stock. Common Stock
certificates issued after the Record Time but prior to the Separation Time shall
evidence one Right for each share of Common Stock represented thereby and shall
contain a legend incorporating by reference the terms of the Rights Agreement
(as such may be amended from time to time). Notwithstanding the absence of the
aforementioned legend, certificates evidencing shares of Common Stock
outstanding at the Record Time shall also evidence one Right for each share of
Common Stock evidenced thereby. Promptly following the Separation Time, separate
certificates evidencing the Rights ("Rights Certificates") will be mailed to
holders of record of Common Stock at the Separation Time.

     The Rights will not be exercisable until the Separation Time. The Rights
will expire on the earliest of (i) the Exchange Time (as defined below); (ii)
the close of business on July 31, 2009; (iii) the date on which the Rights
are redeemed as described below; or (iv) the merger of the Company into
another corporation pursuant to an agreement entered into when there is no
Acquiring Person (in any such case, the "Expiration Time"). The Exercise
Price and the number of Rights outstanding, or in certain circumstances the
securities purchasable upon exercise of the Rights, are subject to adjustment
from time to time to prevent dilution in the event of a Common Stock dividend
on, or a subdivision or a combination into a smaller number of shares of,
Common Stock, or the issuance or distribution of any securities or assets in
respect of, in lieu of or in exchange for Common Stock.

     In the event that prior to the Expiration Time a Flip-in Date occurs, the
Company shall take such action as shall be necessary to ensure and provide, to
the extent permitted by applicable law, that each Right (other than Rights
Beneficially Owned by the Acquiring Person or any Affiliate or Associate
thereof, which Rights shall become void) shall constitute the right to purchase
from the Company, upon the exercise thereof in accordance with the terms of the
Rights Agreement, that number of shares of Common Stock of the Company having an
aggregate Market Price (as defined in the Rights Agreement), on the date of the
public announcement of an Acquiring Person's becoming such (the "Stock
Acquisition Date") that gave rise to the Flip-in Date, equal to twice the
Exercise Price for an amount in cash equal to the then current Exercise Price.
In addition, the Board of Directors of the Company may, at its option, at any
time after a Flip-in Date and prior to the time that an Acquiring Person becomes
the Beneficial Owner of more than 50% of the outstanding shares of Common Stock,
elect to exchange all (but not less than all) the then outstanding Rights (other
than Rights Beneficially Owned by the Acquiring Person or any Affiliate or
Associate thereof, which Rights become void) for shares of Common Stock at an
exchange ratio of one share of Common Stock per Right, appropriately adjusted to
reflect any stock split, stock dividend or similar transaction occurring after
the date of the Separation Time (the "Exchange Ratio"). Immediately upon such
action by the Board of Directors (the "Exchange


                                       -3-

<PAGE>

Time"), the right to exercise the Rights will terminate and each Right will
thereafter represent only the right to receive a number of shares of Common
Stock equal to the Exchange Ratio.

     Whenever the Company shall become obligated under the preceding paragraph
to issue shares of Common Stock upon exercise of or in exchange for Rights, the
Company, at its option, may substitute therefor shares of Participating
Preferred Stock, at a ratio of one one-hundredth of a share of Participating
Preferred Stock for each share of Common Stock so issuable.

     In the event that prior to the Expiration Time the Company enters into,
consummates or permits to occur a transaction or series of transactions after
the time an Acquiring Person has become such, in which directly or indirectly:

          (i) the Company shall consolidate or merge or participate in a binding
share exchange with any other Person if, at the time of the consolidation,
merger or share exchange or at the time the Company enters into an agreement
with respect to such consolidation, merger or share exchange, the Acquiring
Person controls the Board of Directors of the Company and either (A) any term of
or arrangement concerning the treatment of shares of capital stock in such
merger, consolidation or share exchange relating to the Acquiring Person is not
identical to the terms and arrangements relating to other holders of Common
Stock or (B) the Person with whom the transaction or series of transactions
occurs is the Acquiring Person or an Affiliate or Associate of the Acquiring
Person; or

(ii) the Company shall sell or otherwise transfer (or one or more of its
subsidiaries shall sell or otherwise transfer) assets (A) aggregating more than
50% of the assets (measured by either book value or fair market value) or (B)
generating more than 50% of the operating income or cash flow, 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) or to two or more such
Persons which are Affiliates or Associates or otherwise acting in concert, if,
at the time of such sale or transfer of assets or at the time the Company (or
any such subsidiary) enters into an agreement with respect to such sale or
transfer, the Acquiring Person controls the Board of Directors of the Company (a
"Flip-over Transaction or Event"),

the Company shall take such action as shall be necessary to ensure, and shall
not enter into, consummate or permit to occur such Flip-over Transaction or
Event until it shall have entered into a supplemental agreement with the Person
engaging in such Flip-over Transaction or Event or the parent corporation
thereof (the "Flip-over Entity"), for the benefit of the holders of the Rights,
providing that upon consummation or occurrence of the Flip-over Transaction or
Event (i) each Right shall thereafter constitute the right to purchase from the
Flip-over Entity, upon exercise thereof in accordance with the terms of the
Rights Agreement, that number of shares of common stock of the Flip-over Entity
having an aggregate Market Price on the date of consummation or occurrence of
such Flip-over Transaction or Event equal to twice the Exercise Price for an
amount in cash equal to the then current Exercise Price; and (ii) the Flip-over
Entity shall thereafter be liable for, and shall assume, by virtue of such
Flip-over Transaction or Event and such supplemental agreement, all the
obligations and duties of the Company pursuant to the Rights Agreement. For
purposes of the foregoing description, the term "Acquiring Person" shall


                                       -4-

<PAGE>

include any Acquiring Person and its Affiliates and Associates counted together
as a single Person.

     The Board of Directors of the Company may, at its option, at any time prior
to the close of business on the Flip-in Date, redeem all (but not less than all)
the then outstanding Rights at a price of $0.001 per Right (the "Redemption
Price"), as provided in the Rights Agreement. Immediately upon the action of the
Board of Directors of the Company electing to redeem the Rights, without any
further action and without any notice, the right to exercise the Rights will
terminate and each Right will thereafter represent only the right to receive the
Redemption Price in cash or securities, as determined by the Board, for each
Right so held. The holders of Rights will, solely by reason of their ownership
of Rights, have no rights as shareholders of the Company, including, without
limitation, the right to vote or to receive dividends.

     The Rights will not prevent a takeover of the Company. However, the Rights
may cause substantial dilution to a person or group that acquires 10% or more of
the Common Stock unless the Rights are first redeemed by the Board of Directors
of the Company. Nevertheless, the Rights should not interfere with a transaction
that is in the best interests of the Company and its shareholders because the
Rights can be redeemed on or prior to the close of business on the Flip-in Date,
before the consummation of such transaction.

     As of June 30, 1999 there were 1,705,658 shares of Common Stock issued and
outstanding and 544,230 shares reserved for issuance pursuant to certain stock
plans of the Company. As long as the Rights are attached to the Common Stock,
the Company will issue one Right with each new share of Common Stock so that all
such shares will have Rights attached. The Company's Board of Directors has
reserved for issuance upon exercise of the Rights 30,000 shares of Participating
Preferred Stock.

     The Rights Agreement (which includes as Exhibit A the forms of Rights
Certificate and Election to Exercise and as Exhibit B the form of Amendment to
the Articles of Incorporation of the Company) is attached hereto as an exhibit
and is incorporated herein by reference. The foregoing description of the Rights
is qualified in its entirety by reference to the Rights Agreement and such
exhibits thereto.

                     SHAREHOLDER PROTECTION RIGHTS AGREEMENT


     This Shareholder Protection Rights Agreement (the "Agreement"), dated as of
July 23, 1999, is made between Tehama Bancorp, a California corporation (the
"Company"), and U.S. Stock Transfer Corporation (the "Rights Agent").

     Pursuant to this Agreement, the Board of Directors of the Company has
authorized and declared a dividend of one preferred share purchase right (a
"Right") for each Common Share (as hereinafter defined) of the Company
outstanding on August 2, 1999 (the "Record Date"), each Right representing
the right to purchase one one-hundredth 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 with respect to each
Common Share 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).

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

                                   SECTION 1.
                                  DEFINITIONS

     For purposes of this Agreement, the following terms have the meanings
indicated:

     (a)  "Acquiring Person" shall mean any Person (as such term is hereinafter
defined) who or which, together with all Affiliates and Associates (as such
terms are hereinafter defined) of such Person, shall be the Beneficial Owner (as
such term is hereinafter defined) of 10% or more of the Common Shares of the
Company then outstanding, but shall not include the Company, any Subsidiary (as
such term is hereinafter defined) of the Company, any employee benefit plan of
the Company (including without limitation the Employee Plans) or of any
Subsidiary of the Company, or of any entity holding Common Shares for or
pursuant to the terms of any such plan, provided, however, that any Person who
first obtains the written approval of a majority of the Board of Directors of
the Company for the acquisition of 10% or more of the Common Shares of the
Company and therefore accumulates at least 10% of the Common Shares, within six
months of the date of such written approval shall not be an "Acquiring Person."

     Notwithstanding the preceding paragraph, 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 10% or more
of the Common Shares of the Company then outstanding; provided, however, that if
a Person shall become the Beneficial Owner of 10% or more of the Common Shares
of the Company then outstanding by reason of share purchases by the Company and
shall, after such share purchases by the Company, become the Beneficial Owner of
any additional Common Shares of the Company, then such Person shall be deemed to
be an "Acquiring Person".


                                       -1-

<PAGE>

     (b)  "Adjustment Shares" shall have the meaning set forth in Section
11(a)(ii) hereof.

     (c) "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.

     (d)  A Person shall be deemed the "BENEFICIAL OWNER" of and shall be deemed
to "beneficially own" any securities:

          (i)   Which such Person or any of such Person's Affiliates or
     Associates beneficially owns, directly or indirectly;

          (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 (other than
          these Rights), warrants or options, or otherwise; provided, however,
          that a Person shall not be deemed the Beneficial Owner of, or to
          beneficially own, 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 or exchange; 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 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

          (i)  After the Close of Business on the earlier of (A) the tenth day
     after the Shares Acquisition Date, or (B) the tenth Business Day (or such
     later date as may be determined by action of the Board of Directors prior
     to such time as any Person becomes an Acquiring Person) after the date when
     any Person (other than the Company, any Subsidiary of the Company, any
     employee benefit plan of the Company, including without limitation the
     Employee Plans, or of any Subsidiary of the Company or of any entity
     holding Common Shares for or pursuant to the terms of any such plan)
     commences, or first publicly announces an intention to commence, a tender
     or exchange offer which would result in such Person becoming the Beneficial
     Owner of Common Shares aggregating 10% or more of the then outstanding
     Common Shares (the earliest of such dates being herein referred to as the
     "Distribution Date"), the Company shall distribute Rights Certificates in
     accordance with subsection (ii). The provisions of this Section 3(a) shall
     control regardless of whether any Common Shares are actually purchased
     pursuant to such offer, and the Distribution Date may include any date
     which is after the date of this Agreement and prior to the issuance of the
     Rights.

          (ii) 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, insured, postage-prepaid mail, to each
     record holder of Common Shares as of the Close of Business on the
     Distribution Date, at the address of such holder shown on the records of
     the Company, a Rights Certificate, in substantially the form of Exhibit B
     hereto (a "Rights Certificate"), evidencing one Right for each Common Share
     so held. As of the Distribution Date, the Rights will be evidenced solely
     by such Rights Certificates.

     (b)  On the Record Date, or as soon as practicable thereafter, the Company
will send a copy of a Summary of Rights to Purchase Preferred Shares, in
substantially the form of Exhibit C hereto (the "Summary of Rights"), by first-
class, postage-prepaid mail, to each record holder of Common Shares as of the
Close of Business on the Record Date, at the address of such holder shown on the
records of the Company. With respect to certificates for 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
regardless of whether a copy of the Summary of Rights is attached thereto. 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, with or without a copy of the Summary of
Rights attached thereto, shall also constitute the transfer of the Rights
associated with the Common Shares represented thereby.

     (c)  Certificates for Common Shares (including, without limitation,
reacquired Common Shares referred to in the last sentence of this paragraph (c))
which become outstanding 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:


                                       -5-

<PAGE>

     This certificate also evidences and entitles the holder hereof to
     certain rights as set forth in an agreement between Tehama Bancorp and
     U.S. Stock Transfer Corporation dated as of July 23, 1999 (the "Rights
     Agreement"), the terms of which are incorporated herein by reference and
     a copy of which is on file at the principal executive offices of Tehama
     Bancorp. Under certain circumstances, as set forth in the Rights
     Agreement, such Rights will be evidenced by separate certificates and
     will no longer be evidenced by this certificate. Tehama Bancorp 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
     issued to any Person who becomes an Acquiring Person (as defined in the
     Rights Agreement) may become null and void.

     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 shall also constitute the
transfer of the Rights associated with the Common Shares represented thereby. In
the event that the Company purchases or acquires any Common Shares after the
Record Date but prior to the Distribution Date, the Company shall not be
entitled to exercise any Rights associated with such Common Shares while they
are not outstanding.

                                   SECTION 4.
                          FORM OF RIGHTS CERTIFICATES

     The Rights Certificates (and the forms of election to purchase Preferred
Shares and of assignment to be printed on the reverse thereof) shall be
substantially the same as 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 any stock exchange or other organization on which the
Rights may from time to time be listed or quoted, or to conform to usage.
Subject to the provisions of Section 22 hereof, the Rights 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-hundredth
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

     The Rights Certificates shall be executed on behalf of the Company by
its Chairman of the Board, its Chief Executive Officer, its President, or any of
its Executive Vice Presidents, either manually or by facsimile signature and
shall be attested by the Secretary or an Assistant Secretary of the Company,
either manually or by facsimile signature. The Rights 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


                                       -6-

<PAGE>


Rights Certificates shall cease to be such officer of the Company before
countersignature by the Rights Agent and issuance and delivery by the Company,
such Rights 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 Rights Certificates had not ceased to be such officer
of the Company; and any Rights Certificate may be signed on behalf of the
Company by any person who, at the actual date of the execution of such Rights
Certificate, shall be a proper officer of the Company to sign such Rights
Certificate, although at the date of the execution of this Agreement any such
person was not such an officer.

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

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

     Subject to the provisions of Section 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 Rights
Certificate or Rights Certificates, other than Rights 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 Rights Certificate or Rights Certificates,
entitling the registered holder to purchase a like number of one one-hundredths
of a Preferred Share as the Rights Certificate or Rights Certificates
surrendered then entitled such holder to purchase. Any registered holder
desiring to transfer, split up, combine or exchange any Rights Certificate or
Rights Certificates shall make such request in writing delivered to the Rights
Agent, and shall surrender the Rights Certificate or Rights Certificates to be
transferred, split up, combined or exchanged at the principal office of the
Rights Agent. Thereupon the Rights Agent shall countersign and deliver to the
person entitled thereto a Rights Certificate or Rights Certificates, as the case
may be, as so requested. The Company may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer, split up, combination or exchange of Rights Certificates.

     Upon receipt by the Company and the Rights Agent of evidence reasonably
satisfactory to them of the loss, theft, destruction or mutilation of a Rights
Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to them and 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 Rights Certificate if
mutilated, the Company will make and deliver a new Rights Certificate of like
tenor to the Rights Agent for delivery to the registered holder in lieu of the
Rights Certificate so lost, stolen, destroyed or mutilated.

                                   SECTION 7.
          EXERCISE OF RIGHTS; PURCHASE PRICE; EXPIRATION DATE OF RIGHTS

     (a)  The registered holder of any Rights Certificate may exercise the
Rights evidenced thereby (except as otherwise provided herein) in whole or in
part at any time after the Distribution Date upon surrender of the Rights
Certificate, with the form of election to purchase on the reverse side thereof
duly executed, to the Rights Agent at the principal office of the Rights Agent,
together with payment of the Purchase Price for each one one-hundredth of a
Preferred Share as to which the Rights are exercised, at or prior to the
earliest of (i) the Close of Business on July 31, 2009 (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 for each one one-hundredth of a Preferred Share
pursuant to the exercise of a Right shall initially be $55.00, 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) below.

     (c)  Upon receipt of a Rights Certificate representing exercisable Rights,
with the form of election to purchase duly executed, accompanied by payment of
the Purchase Price for the shares to be purchased and an amount equal to any
applicable transfer tax required to be paid by the holder of such Rights
Certificate in accordance with Section 9 hereof by cash, certified check,
cashier's check or money order payable to the order of the Company, the Rights
Agent shall thereupon promptly:

          (i)   Requisition (A) 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 of the Preferred
     Shares to comply with all such requests, or (B) from the depository agent,
     depository receipts representing 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 depository agent) and the Company hereby directs
     the depository 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) After receipt of such certificates or depository receipts, cause
     the same to be delivered to or upon the order of the registered holder of
     such Rights Certificate, registered in such name or names as may be
     designated by such holder; and

          (iv)  When appropriate, after receipt, deliver such cash to or upon
     the order of the registered holder of such Rights Certificate.


                                       -8-

<PAGE>

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

     (e)  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 in
accordance with this Section 7.

                                   SECTION 8.
              CANCELLATION AND DESTRUCTION OF RIGHTS CERTIFICATES

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

                                   SECTION 9.
                        AVAILABILITY OF PREFERRED SHARES

     The Company covenants and agrees that it will take all such action as may
be necessary to ensure that all Preferred Shares delivered upon exercise of
Rights shall, at the time of delivery of the certificates for such Preferred
Shares (subject to payment of the Purchase Price), be duly and validly
authorized and issued, fully paid and nonassessable.

     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 Rights Certificates or of
any Preferred Shares 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 Rights Certificates to a Person other than, or the
issuance or delivery of certificates or depository receipts for the Preferred
Shares in a name other than that of, the registered holder of the Rights
Certificate evidencing Rights surrendered for exercise or to issue or to deliver
any certificates or depository receipts for Preferred Shares upon the exercise
of any Rights until any such tax shall have been paid (any such tax being
payable by the holder of such Rights Certificate at the time of surrender) or
until it has been established to the Company's 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 Rights Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
(and any applicable transfer taxes) was made; provided, however, that if the
date of such surrender and payment is a date upon which the Preferred 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 Rights 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 rights to vote, to receive dividends or other
distributions or to exercise any preemptive rights, and shall not be entitled to
receive any notice of any proceedings of the Company, except as provided herein.

                                   SECTION 11.
                          ADJUSTMENT OF PURCHASE PRICE,
                      NUMBER OF SHARES OR NUMBER OF RIGHTS

     (a)  The Purchase Price, the number of Preferred Shares covered by each
Right and the number of Rights outstanding shall be subject to adjustment from
time to time as provided in this Section 11.

          (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 Rights


                                      -10-

<PAGE>

     exercised after such time shall be entitled to receive the aggregate number
     and kind of shares of capital stock which, if such Rights had been
     exercised immediately prior to such date and at a time when the Preferred
     Shares transfer books of the Company were open, such holder would have
     owned upon such exercise and been entitled to receive by virtue of such
     dividend, subdivision, combination or reclassification; provided, however,
     that in no event shall the consideration to be paid upon the exercise of
     one Right be less than the aggregate par value of the shares of capital
     stock of the Company issuable upon exercise of one Right.

          (ii) Subject to Section 24 of this Agreement, in the event:

               (A)  A Trigger Event shall have occurred (other than through an
          acquisition described in subparagraph (iii) of this paragraph (a)); or

               (B)  During such time as there is an Acquiring Person, there
          shall be any reclassification of securities (including any reverse
          stock split), or recapitalization or reorganization of the Company or
          other transaction or series of transactions involving the Company
          which has the effect, directly or indirectly, of increasing by more
          than 1% the proportionate share of the outstanding shares of any class
          of equity securities of the Company or any of its Subsidiaries
          beneficially owned by any Acquiring Person or any Affiliate or
          Associate thereof,

each holder of a Right shall thereafter have a right to receive, upon exercise
thereof at a price equal to the then current Purchase Price multiplied by the
number of one one-hundredths of a Preferred Share for which a Right is then
exercisable, in accordance with the terms of this Agreement and in lieu of
Preferred Shares, such number of Common Shares of the Company (such number of
shares being referred to herein as the "Adjustment Shares") as shall equal the
result obtained by (x) multiplying the then current Purchase Price by the number
of one one-hundredths of a Preferred Share for which a Right is then
exercisable, and dividing that product by (y) 50% of the then current per share
market price of the Company's Common Shares (determined pursuant to Section
11(d) hereof) on the date of the occurrence of the earliest of the events
described in clauses (A) and (B) above.

     From and after the occurrence of the earliest of the events described in
clauses (A) and (B) above, any Rights that are or were acquired or are or were
beneficially owned by any Acquiring Person (or any Associate or Affiliate of
such Acquiring Person) shall be void and any holder of such Rights (including
any subsequent transferee) shall thereafter have no right to exercise such
Rights under any provision of this Agreement. No Rights Certificate shall be
issued pursuant to Section 3 that represents Rights beneficially owned by an
Acquiring Person whose Rights would be void pursuant to the preceding sentence
or any Associate or Affiliate thereof; no Rights Certificate shall be issued at
any time upon the transfer of any Rights to an Acquiring Person whose Rights
would be void pursuant to the preceding sentence or any Associate or Affiliate
thereof or to any nominee of such Acquiring Person, Associate or Affiliate;

<PAGE>

and any Rights Certificate delivered to the Rights Agent for transfer to an
Acquiring Person whose Rights would be void pursuant to the preceding sentence
shall be canceled.

          (iii) The right to buy Common Shares of the Company pursuant to
     subparagraph (ii) of this paragraph (a) shall not arise as a result of any
     Person becoming an Acquiring Person through a purchase of Common Shares
     pursuant to a tender offer made in the manner prescribed by Section 14(d)
     of the Exchange Act and the rules and regulations promulgated thereunder;
     provided, however, that such tender offer shall provide for the acquisition
     of all of the outstanding Common Shares held by any Person other than such
     Acquiring Person and its Affiliates or Associates at a price and on terms
     determined by at least a majority of the members of the Board of Directors
     who are not officers of the Company and who are not representatives,
     nominees, Affiliates or Associates of an Acquiring Person, after receiving
     advice from one or more investment or financial advisers, to be (A) fair to
     shareholders, taking into account all factors which such members of the
     Board deem relevant including, without limitation, prices which could
     reasonably be achieved if the Company or its assets were sold on an orderly
     basis designed to realize maximum value, and (B) otherwise in the best
     interests of the Company and its shareholders, employees, customers and
     communities in which the Company does business.

          (iv)  In the event that there shall not be sufficient Common Shares
     authorized but unissued to permit the exercise in full of the Rights in
     accordance with the foregoing subparagraph (ii), the Company shall:

               (A)  Determine the excess of (1) the value of the Adjustment
          Shares issuable upon the exercise of a Right (the "Current Value"),
          over (2) the Purchase Price (such excess being hereinafter referred to
          as the "Spread"); and

               (B)  With respect to each Right, make adequate provision to
          substitute for such unavailable Adjustment Shares either (1) cash, (2)
          a reduction in the Purchase Price, (3) other equity securities of the
          Company, including without limitation, Preferred Shares, (4) debt
          securities of the Company, (5) other assets, or (6) any combination of
          the foregoing having, together with the Adjustment Shares issued upon
          exercise of such Right, an aggregate value equal to the Current Value,
          where such aggregate value has been determined by the Board of
          Directors of the Company based upon the advice of a reputable
          investment banking firm selected by the Board of Directors of the
          Company.

     Notwithstanding the provisions of the preceding paragraph, if, within 30
days following the date of the occurrence of the earliest of the events
described in clauses (A) and (B) of Section 11(a)(ii) above, the Company shall
have not made adequate provision to deliver value pursuant to clause (B) above,
then the Company shall be obligated to deliver, upon the surrender for exercise
of a Right and without requiring payment of the Purchase Price, Common Shares
(to the extent such shares are available) and then, if necessary, cash or
Preferred Shares, which shares and/or cash have an aggregate value equal to the
Spread. If the Board of Directors of the


                                      -12-

<PAGE>

Company shall determine in good faith that it is likely that sufficient
additional Common Shares could be authorized for issuance upon exercise in full
of the Rights, the 30-day period set forth above may be extended to the extent
necessary, but not more than 120 days following the date of the occurrence of
the earliest of the events described in clauses (A) and (B) of Section 11(a)(ii)
above, in order that the Company may seek shareholder approval for the
authorization of such additional shares (such period, as it may be extended,
hereinafter referred to as the "Substitution Period").

     To the extent that the Company determines that action needs be taken
pursuant to the first and/or second sentences of this Section 11(a)(iv), the
Company (x) shall provide, subject to Section 11(a)(ii) 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 first 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)(iv),
the value of the Common Shares shall be the current per share market price (as
determined pursuant to Section 11(d) hereof) per Common Share on the date of the
occurrence of the earliest of the events described in clauses (A) and (B) of
Section 11(a)(ii) above.

     (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 (as defined in Section 11(d)) 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 outstanding on such record date plus the number of Preferred
Shares which the aggregate offering price of the total number of Preferred
Shares and/or 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 Shares outstanding on such record date plus the number of
additional Preferred Shares and/or equivalent preferred shares to be offered for
subscription or purchase (or into which the convertible securities so to be
offered are initially convertible).

     In case such subscription price may be paid 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 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


                                      -13-

<PAGE>

be made successively whenever such 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 on such
record date, less the fair market value (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) 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 of the Preferred Shares. 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)  For the purpose of any computation hereunder:

          (i)  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 20 consecutive Trading Days (as such term is hereinafter
     defined) immediately prior to such date. In the event that the current per
     share market price of the Security is determined:

               (A)  During a period following the announcement by the issuer of
          such Security of:

                    (1)  A dividend or distribution on such Security payable in
               shares of such Security or securities convertible into such
               shares; or

                    (2)  Any subdivision, combination or reclassification of
               such Security, and

               (B)  Prior to the expiration of 20 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 or, in case no such sale takes place


                                      -14-

<PAGE>

     on such day, the average of the closing bid and asked prices in either case
     as reported in the principal consolidated transaction reporting system with
     respect to securities listed or admitted to trading on the New York Stock
     Exchange or, if the Security is not listed or admitted to trading on the
     New York Stock Exchange, 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 reported trade in the
     over-the-counter market, as reported by the Nasdaq National Market
     ("Nasdaq") or such other system then in use, or, if on any such date 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.
     If on any such date no such market maker is making a market in the
     Security, the fair value of the Security on such date as determined in good
     faith by the Board of Directors of the Company shall be used.

          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, 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, the "current per share market price" of the
     Preferred Shares shall be conclusively deemed to be the current per share
     market price of the Common Shares as determined pursuant to Section
     11(d)(i) (appropriately adjusted to reflect any stock split, stock dividend
     or similar transaction occurring after the date hereof), multiplied by one
     hundred. If neither the Common Shares nor the Preferred Shares are publicly
     held or so listed or traded, "current per share market price" shall mean
     the fair value per share 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.

     (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 one one-hundredth of any 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.


                                      -15-

<PAGE>

     (f)  If as a result of an adjustment made pursuant to Section 11(a) hereof,
the holder of any Rights 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
Rights 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 Section 11(a) through (c), inclusive, 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) below, 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 one-hundredth
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 this
adjustment by (y) the Purchase Price in effect immediately prior to such
adjustment of the Purchase Price and (ii) dividing the product so obtained by
the Purchase Price in effect immediately after such adjustment of the Purchase
Price.

     (i)  The Company may elect on or after the date of any adjustment of the
Purchase Price to adjust the number of Rights, in 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 one-hundredth) obtained by dividing the Purchase
Price in effect immediately prior to adjustment of the Purchase Price by the
Purchase Price in effect immediately after adjustment of the Purchase Price. The
Company shall make a public announcement of its election to adjust the number of
Rights, indicating the record date for the adjustment, and, if known at the
time, the amount of the adjustment to be made. This record date may be the date
on which the Purchase Price is adjusted or any day thereafter, but, if the
Rights Certificates have been issued, shall be at least 10 days later than the
date of the public announcement.

     If Rights Certificates have been issued, upon each adjustment of the number
of Rights pursuant to this Section 11(i), the Company shall, as promptly as
practicable, cause to be distributed to holders of record of Rights Certificates
on such record date Rights Certificates evidencing, subject to Section 14
hereof, the additional Rights to which such holders shall be entitled as a
result of such adjustment, or, at the option of the Company, shall cause to be
distributed to such holders of record in substitution and replacement for the
Rights Certificates held by such holders prior to the date of adjustment, and
upon surrender thereof, if required by


                                      -16-

<PAGE>

the Company, new Rights Certificates evidencing all the Rights to which such
holders shall be entitled after such adjustment. Rights 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
Rights Certificates on the record date specified in the public announcement.

     (j)  Irrespective of any adjustment or change in the Purchase Price or the
number of one one-hundredths of a Preferred Share issuable upon the exercise of
the Rights, the Rights Certificates previously and thereafter issued may
continue to express the Purchase Price and the number of one one-hundredths of a
Preferred Share that were expressed in the initial Rights Certificates issued
hereunder.

     (k)  Before taking any action that would cause an adjustment reducing the
Purchase Price below one one-hundredth of the then par value, if any, of the
Preferred Shares 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 at such adjusted Purchase Price.

     (1)  In any case in which this Section 11 shall require that an adjustment
in the Purchase Price be made effective as of a record date for a specified
event, the Company may elect to defer until the occurrence of such event the
issuing to the holder of any Rights 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 Shares, issuance
wholly for cash of any Preferred Shares at less than the current 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 shareholders.

     (n)  The Company covenants and agrees that it shall not, at any time after
the Distribution Date, (i) consolidate with, or merge with and into, any other
Person (other than a Subsidiary of the Company in a transaction that complies
with Section 11(o)), (ii) permit or cause any Person to consolidate with the
Company, or merge with and into the Company (other than a Subsidiary of the
Company in a transaction that complies with Section 11(o)), or (iii) sell or
otherwise transfer (or permit any Subsidiary to sell or transfer), in one or
more transactions, assets or earning power aggregating 50% or more of the assets
or earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person or Persons (other than the Company


                                       -17-

<PAGE>

and/or any of its Subsidiaries in one or more transactions each of which
complies with Section 11(o)), if at the time of or immediately after such
consolidation, merger or sale there are any rights, warrants or other
instruments or securities outstanding or agreements in effect that would
substantially diminish or otherwise eliminate the benefits intended to be
afforded by the Rights.

     (o)  The Company covenants and agrees that, after the Distribution Date, it
will not, except as permitted by Section 23, Section 24 or Section 27 hereof,
take (or permit any Subsidiary of the Company to take) any action if at the time
such action is taken it is reasonably foreseeable that such action will diminish
substantially or otherwise eliminate the benefits intended to be afforded by the
Rights.

     (p)  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 (A) the
number of one one-hundredths of a Preferred Share purchasable after such event
upon proper exercise of each Right shall be determined by multiplying the number
of one one-hundredths of a Preferred Share so purchasable immediately prior to
such event by a fraction, the numerator of which is the number of Common Shares
outstanding immediately before such event and the denominator of which is the
number of Common Shares outstanding immediately after such event, and (B) each
Common Share outstanding immediately after such event shall have issued with
respect to it that number of Rights which each Common Share outstanding
immediately prior to such event had issued with respect to it. The adjustments
provided for in this Section 11(p) shall be made successively whenever such a
dividend is declared or paid or such a subdivision, combination or consolidation
is effected.

                                   SECTION 12.
                             CERTIFICATE OF ADJUSTED
                       PURCHASE PRICE OR NUMBER OF SHARES

     Whenever an adjustment is made as provided in Sections 11 and 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,
(b) file with the Rights Agent and with each transfer agent for the Common
Shares or the Preferred Shares a copy of such certificate and (c) mail a brief
summary thereof to each holder of a Rights Certificate in accordance with
Section 25 hereof.

     (a)  If, following the Distribution Date, directly or indirectly:


                                      -19-
<PAGE>

          (i)   The Company shall consolidate with, or merge with and into, any
     other Person and the Company shall not be the continuing or surviving
     corporation of such consolidation or merger;

          (ii)  Any Person shall consolidate with the Company, or 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 the Company) or cash or any other
     property;

          (iii) Any Person shall acquire all or a majority of the Common Shares
     pursuant to a statutory plan of exchange; or

          (iv)  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 earning power aggregating 50% or more of the assets
     or earning 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, and in each such case, proper provision shall be made so that:

          (A)  Each holder of a Right (except as otherwise provided herein)
     shall thereafter have the right to receive, upon the exercise thereof at a
     price equal to the then current Purchase Price multiplied by the number of
     one one-hundredths of a Preferred Share for which a Right is then
     exercisable, in accordance with the terms of this Agreement and in lieu of
     Preferred Shares, such number of Common Shares of the Principal Party (as
     hereinafter defined), not subject to any liens, encumbrances, rights of
     first refusal or other adverse claims, as shall equal the result obtained
     by (1) multiplying the then current Purchase Price by the number of one
     one-hundredths of a Preferred Share for which a Right is then exercisable
     and dividing that product by (2) 50% of the then current per share market
     price of the Common Shares (determined pursuant to Section 11(d) hereof) of
     such Principal Party on the date of consummation 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 Agreement;

          (C)  The term "Company" shall thereafter be deemed to refer to such
     Principal Party, it being specifically intended that the provisions of
     Section 11 shall apply only to such Principal Party after the first
     occurrence of an event described in this Section 13(a);

          (D)  Such Principal Party shall take such steps (including, but not
     limited to, the reservation of a sufficient number of its Common Shares in
     accordance with Section 9 hereof) in connection with such consummation as
     may be necessary to assure that the


                                      -20-

<PAGE>

     provisions hereof shall thereafter be applicable, as nearly as reasonably
     may be, in relation to the Common Shares thereafter deliverable upon the
     exercise of the Rights; and

          (E)  The provisions of Section 11(a)(ii) shall be of no further effect
     following the first occurrence of any event described in this Section
     13(a).

     (b)  "Principal Party" shall mean:

          (i)  In the case of any transaction described in clause (i), (ii) or
     (iii) of Section 13(a):

               (A)  The Person that is the issuer of any securities into which
          Common Shares of the Company are converted in such merger,
          consolidation or for which they are exchanged in such statutory plan
          of exchange, or, if there is more than one such issuer, the issuer of
          Common Shares that has the highest aggregate current market price
          (determined in accordance with Section 11(d)); and

               (B)  If no securities are so issued, the Person that is the other
          party to such merger, consolidation or statutory plan of exchange, or,
          if there is more than one such Person, the Person whose Common Shares
          have the highest aggregate current market price (determined in
          accordance with Section 11(d)); and

          (ii) in the case of any transaction described in clause (iv) of
     Section 13(a), the Person that is the party receiving the largest portion
     of the assets or earning power transferred pursuant to such transaction or
     transactions, or, if each Person that is a party to such transaction or
     transactions receives the same portion of the assets or earning power
     transferred pursuant to such transaction or transactions or if the Person
     receiving the largest portion of the assets or earning power cannot be
     determined, whichever Person whose Common Shares have the highest aggregate
     current market price (determined in accordance with Section 11(d));
     provided, however, that in any such case:

               (A)  If the Common Shares of such Person are not at such time and
          have not been continuously over the preceding twelve-month period
          registered under Section 12 of the Exchange Act ("Registered Common
          Shares"), or such Person is not a corporation, and such Person is a
          direct or indirect Subsidiary of another Person that has Registered
          Common Shares outstanding, "Principal Party" shall refer to such other
          Person;

               (B)  If the Common Shares of such Person are not Registered
          Common Shares or such Person is not a corporation, and such Person is
          a direct or indirect Subsidiary of another Person but is not a direct
          or indirect Subsidiary of another Person which has Registered Common
          Shares outstanding, "Principal Party" shall refer to the ultimate
          parent entity of such first-mentioned Person;


                                      -21-

<PAGE>

               (C)  If the Common Shares of such Person are not Registered
          Common Shares or such Person is not a corporation, and such Person is
          directly or indirectly controlled by more than one Person, and one or
          more of such other Persons has Registered Common Shares outstanding,
          "Principal Party" shall refer to whichever of such other Persons is
          the issuer of the Registered Common Shares having the highest
          aggregate current market price (determined in accordance with Section
          11(d)); and

               (D)  If the Common Shares of such Person are not Registered
          Common Shares or such Person is not a corporation, and such Person is
          directly or indirectly controlled by more than one Person, and none of
          such other Persons have Registered Common Shares outstanding,
          "Principal Party" shall refer to whichever ultimate parent entity is
          the corporation having the greatest shareholders' equity or, if no
          such ultimate parent entity is a corporation, shall refer to whichever
          ultimate parent entity is the entity having the greatest net assets.

     (c)  The Company shall not consummate any such consolidation, merger,
statutory plan of exchange, sale or transfer unless prior thereto the Company
and the Principal Party shall have executed and delivered to the Rights Agent a
supplemental agreement confirming that:

          (i)   Such Principal Party shall, upon consummation of such
     consolidation, merger, statutory plan of exchange or sale or transfer of
     assets or earning power, assume this Agreement in accordance with Section
     13;

          (ii)  All rights of first refusal or preemptive rights in respect of
     the issuance of Common Shares of such Principal Party upon exercise of
     outstanding Rights have been waived;

          (iii) Any provision of the authorized securities of such Principal
     Party or of its charter, bylaws or other instruments governing its
     corporate affairs which would obligate such Principal Party to issue in
     connection with, or as a consequence of, the consummation of a transaction
     referred to in Section 13(a), Common Shares of such Principal Party at less
     than the then-current per share market price (determined in accordance with
     Section 11(d)(i)) or securities exercisable for, or convertible into, such
     Common Shares at less than such then- current per share market price (other
     than to the holders of Rights pursuant to this Section 13) have been waived
     or canceled; and

          (iv)  Such transaction shall not result in a default by such Principal
     Party under this Agreement, and further providing that, as soon as
     practicable after the date of any consolidation, merger, statutory plan of
     exchange or sale or transfer of assets or earning power referred to in
     Section 13(a), such Principal Party will:

               (A)  Prepare and file a registration statement under the
          Securities Act of 1933, as amended, with respect to the Rights and the
          securities purchasable upon


                                      -22-

<PAGE>

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

               (B)  Use its best efforts to list (or continue the listing of)
          the Rights and the securities purchasable upon exercise of the Rights
          or to meet the eligibility requirements for quotation of the Rights
          and such securities on Nasdaq or other system then in use; and

               (C)  Deliver to holders of the Rights historical financial
          statements for such Principal Party which comply in all respects with
          the requirements for registration on Form 10 (or any successor form)
          under the Exchange Act.

     In the event that at any time after the occurrence of an event described in
Section 11(a)(ii) hereof some or all of the Rights shall not have then been
exercised at the time of the occurrence of an event described in Section 13(a)
hereof, the Rights which have not theretofore been exercised shall thereafter be
exercisable in the manner described in Section 13(a) (without taking into
account any prior adjustment required by Section 11(a)(ii)).

     (d)  The provisions of this Section 13 shall similarly apply to successive
mergers or consolidations or sales or other transfers.

     (e)  Notwithstanding anything in this Agreement to the contrary, this
Section 13 shall not be applicable to a transaction described in Section
13(a)(i), (ii) or (iii) if: (i) such transaction is consummated with a Person or
Persons who acquired Common Shares pursuant to a tender offer described in
Section 11(a)(iii) (or with a wholly-owned Subsidiary of any such Person or
Persons), (ii) the price per Common Share offered in such transaction is not
less than the price per Common Share paid to all holders of Common Shares whose
shares were purchased pursuant to such tender or exchange offer, and (iii) the
form of consideration being offered to the remaining holders of Common Shares
pursuant to such transaction is the same as the form of consideration paid
pursuant to such tender offer. Upon consummation of any such transaction
contemplated by this Section 13(e), all Rights shall expire.

                                   SECTION 14.
                     FRACTIONAL RIGHTS AND FRACTIONAL SHARES

     (a)  The Company shall not be required to issue fractions of Rights or to
distribute Rights Certificates which evidence fractional Rights. In lieu of such
fractional Rights, there shall be paid to the registered holders of the Rights
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


                                      -23-

<PAGE>

the date on which such fractional Right would have been otherwise issuable. The
closing price for any day shall be the last sale price, or, in case no such sale
takes place on such day, the average of the closing bid and asked prices, in
either case as reported in the principal consolidated transaction reporting
system with respect to securities listed or admitted to trading on the New York
Stock Exchange or, if the Rights are not listed or admitted to trading on the
New York Stock Exchange, as reported in the principal consolidated transaction
reporting system with respect to securities listed on the principal national
securities exchange on which the Rights are listed or admitted to trading or, if
the Rights are not listed or admitted to trading on any national securities
exchange, the last reported trade 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.

     (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). 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 depository receipts,
pursuant to an appropriate agreement between the Company and a depository
selected by it; provided, that such agreement shall provide that the holders of
such depository receipts shall have all the rights, privileges and preferences
to which they are entitled as beneficial owners of the Preferred Shares
represented by such depository 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 Rights Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market 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)
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 Rights Certificates (and, prior to the
Distribution Date, the registered holders of the Common Shares); and any
registered holder of any Rights Certificate (or, prior to the Distribution Date,
of the Common Shares), without the consent of the holder of any other Rights
Certificate (or, prior to the Distribution Date, of the Common Shares), may, in
his own behalf and for his own benefit, 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 Rights


                                      -24-

<PAGE>

Certificate in the manner provided in such Rights Certificate and in this
Agreement. Without limiting the foregoing or any remedies available to the
holders of Rights, it is specifically acknowledged that the holders of Rights
would not have an adequate remedy at law for any breach of this Agreement and
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 RIGHTS HOLDERS

          Every holder of a Right, by accepting the same, consents and agrees
with the Company and with every other holder of a Right that:

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

     (b)  After the Distribution Date, the Rights Certificates are transferable
only on the registry books of the Rights Agent if surrendered at the principal
office of the Rights Agent, duly endorsed or accompanied by a proper instrument
of transfer; and

     (c)  The Company may deem and treat the person in whose name the Rights
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
Rights 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.
               RIGHTS CERTIFICATE HOLDER NOT DEEMED A SHAREHOLDER

     No holder of any Rights Certificate, by reason only of being a holder of
such Rights 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 contained herein or in any
Rights Certificate be construed to confer upon the holder of any Rights
Certificate, by reason only of being a holder of such Rights Certificate, any of
the rights of a shareholder of the Company or any right to vote for the election
of directors or upon any matter submitted to shareholders at any meeting
thereof, or to give or withhold consent to any corporate action, or to receive
notice of meetings or other actions affecting shareholders (except as provided
in Section 25 hereof), or to receive dividends or subscription rights, or
otherwise, until the Right or Rights evidenced by such Rights Certificate shall
have been exercised in accordance with the provisions hereof.

               FEES, EXPENSES AND LIABILITIES OF THE RIGHTS AGENT

     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 in the
premises.

     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 Rights Certificate or
certificate for the Preferred Shares or 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

     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 business 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 Rights 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 Rights
Certificates so countersigned; and in case at that time any of the Rights
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Rights Certificates either in the name of the predecessor
Rights Agent or in the name of the successor Rights Agent; and in all such cases
such Rights Certificates shall have the full force provided in the Rights
Certificates and in this Agreement.

     In case at any time the name of the Rights Agent shall be changed and at
such time any of the Rights Certificates shall have been countersigned but not
delivered, the Rights Agent may adopt the countersignature under its prior name
and deliver Rights Certificates so countersigned; and in case at that time any
of the Rights Certificates shall not have been countersigned, the


                                      -26-

<PAGE>

Rights Agent may countersign such Rights Certificates either in its prior name
or in its changed name; and in all such cases such Rights Certificates shall
have the full force provided in the Rights Certificates and in this Agreement.

                                   SECTION 20.
                             DUTIES OF RIGHTS AGENT

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

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

     (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, the
Chief Executive Officer, the President, any Executive Vice President, 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 willful misconduct.
Anything in this Agreement to the contrary notwithstanding, in no event shall
the Rights Agent be liable for special, indirect or consequential loss or damage
of any kind whatsoever (including, but not limited to, lost profits), even if
the Rights Agent has been advised of the likelihood of such loss or damage and
regardless of the form of action.

     (d)  The Rights Agent shall not be liable for or by reason of any of the
statements of fact or recitals contained in this Agreement or in the Rights
Certificates (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 Rights 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 Rights 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


                                      -27-

<PAGE>

the manner, method or amount thereof) provided for in Sections 3, 11, 13, 23 or
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
Rights Certificates after actual notice that such change or adjustment is
required); nor shall it 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 Rights
Certificate or as to whether any Preferred Shares will, when issued, be duly and
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
one of the Chairman of the Board, the Chief Executive Officer, the President,
any Executive Vice President, or the Secretary 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.

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

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

                                   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
Rights 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 Rights Certificates by first-class
mail. If the Rights Agent shall resign or be removed or shall


                                      -28-

<PAGE>

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 Rights Certificate (who shall,
with such notice, submit his Rights Certificate for inspection by the Company),
then the registered holder of any Rights Certificate may apply to any court of
competent jurisdiction for the appointment of a new Rights Agent.

     Any successor Rights Agent, whether appointed by the Company or by such
a court, shall be a corporation (or an affiliate of a corporation) organized
and doing business under the laws of the United States or any state of the
United States so long as such corporation is authorized to do business as a
banking institution, is authorized under such laws to exercise corporate
trust or stock transfer powers, is in good standing, and is subject to
supervision or examination by federal or state authority, and has at the time
of its appointment as Rights Agent a combined capital and surplus of at least
$50 million. 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 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 RIGHTS CERTIFICATES

     Notwithstanding any of the provisions of this Agreement or of the Rights to
the contrary, the Company may, at its option, issue new Rights Certificates
evidencing Rights in such form as may be approved by 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.

                                   SECTION 23.
                                   REDEMPTION

     (a)  The Board of Directors of the Company may, at its option, at any time
prior to such time as any Person becomes an Acquiring Person, redeem all but not
less than all the then outstanding Rights at a redemption price of $0.001 per
Right, appropriately adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof (such redemption price being
hereinafter referred to as the "Redemption Price"); provided, however,


                                      -29-

<PAGE>

that if, following the occurrence of a Shares Acquisition Date and following the
expiration of the right of redemption hereunder but prior to any event described
in clause (B) of Section 11(a)(ii) or clauses (i), (ii), (iii) or (iv) of
Section 13(a) hereof:

          (i)  A Person who is an Acquiring Person shall have transferred or
     otherwise disposed of a number of shares of Common Shares in one
     transaction or series of transactions, not directly or indirectly involving
     the Company or any of its Subsidiaries, which did not result in the
     occurrence of an event described in clause (B) of Section 11(a)(ii) or
     clauses (i), (ii), (iii) or (iv) of Section 13(a) hereof such that such
     Person is thereafter a Beneficial Owner of less than 10% of the outstanding
     Common Shares; and

          (ii) There are no other Persons, immediately following the occurrence
     of the event described in clause (i), who are Acquiring Persons,

then the right of redemption shall be reinstated and thereafter be subject to
the provisions of this Section 23. The redemption of the Rights by the Board of
Directors may be made effective at such time, on such basis and with such
conditions as the Board of Directors in its sole discretion may establish. The
Company may, in its discretion, round up the redemption price to be paid to any
holder of Rights to the nearest whole cent.

     (b)  Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights pursuant to paragraph (a) of
this Section 23, 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 the
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 will 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 any Person becomes an Acquiring Person, 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 Common
Shares at an exchange ratio of one Common Share per Right, appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof (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 the Company, any


                                      -30-

<PAGE>

Subsidiary of the Company, any employee benefit plan of the Company, including
without limitation the Employee Plans, or of any such Subsidiary, or of any
entity holding Common Shares for or pursuant to the terms of any such plan),
together with all Affiliates and Associates of such Person, becomes the
Beneficial Owner of 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 subsection (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 Common Shares
equal to the number of such Rights held by such holder multiplied by the
Exchange Ratio. The Company shall promptly give public notice of any such
exchange; provided, however, that the failure to give, or any defect in, such
notice shall not affect the validity of such exchange. The Company promptly
shall mail a notice of any such exchange to all of the holders of such Rights
at their last addresses as they appear upon the registry books of the Rights
Agent. Any notice which is mailed in the manner herein provided shall be
deemed given, whether or not the holder receives the notice. Each such notice
of exchange will state the method by which the exchange of the Common Shares
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 any exchange pursuant to this Section 24, the Company, at its
option, may substitute Preferred Shares (or equivalent preferred shares, as such
term is defined in Section 11(b) hereof) for Common Shares exchangeable for
Rights, at the initial rate of one one-hundredth of a Preferred Share (or
equivalent preferred share) for each Common Share, as appropriately adjusted to
reflect adjustments in the voting rights of the Preferred Shares pursuant to the
terms thereof, so that the fraction of a Preferred Share delivered in lieu of
each Common Share shall have the same voting rights as one Common Share.

     (d)  In the event that there shall not be sufficient Common Shares or
Preferred Shares issued but not outstanding or authorized but unissued to permit
any exchange of Rights as contemplated in accordance with this Section 24, the
Company shall use its best efforts to cause all such action to be taken as may
be necessary to authorize additional Common Shares or Preferred Shares for
issuance upon exchange of the Rights.

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

                            NOTICE OF CERTAIN EVENTS

     (a)  In case the Company shall propose to:

          (i)   Pay any dividend payable in stock of any class to the holders of
     its Preferred Shares or to make any other distribution to the holders of
     its Preferred Shares (other than a regular quarterly cash dividend);

          (ii)  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) Effect any reclassification of its Preferred Shares (other than
     a reclassification involving only the subdivision of outstanding Preferred
     Shares);

          (iv)  Effect any consolidation or merger into or with, or to effect
     any sale or other transfer (or to permit one or more of its Subsidiaries to
     effect any sale or other transfer), in one or more transactions, of 50% or
     more of the assets or earning power of the Company and its Subsidiaries
     (taken as a whole) to, any other Person;

          (v)   Effect the liquidation, dissolution or winding up of the
     Company; or

          (vi)  Declare or pay any dividend on the Common Shares payable in
     Common Shares or effect a subdivision, combination or consolidation of the
     Common Shares (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 Rights
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
reclassification, consolidation, merger, sale, transfer, liquidation,
dissolution, or winding up is to take place and the date of participation
therein by the holders of the Common Shares and/or Preferred Shares, if any such
date is to be fixed. 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 of the events set forth in Section 11(a)(ii) hereof shall
occur, then the Company shall as soon as practicable thereafter give to each
holder of a Rights Certificate, 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) hereof.

such time as the suspension is no longer in effect. Notwithstanding any

                                 TEHAMA BANCORP


     Pursuant to Section 401 of the California Corporations Code of the State of
California:

     We, William P. Ellison, President and Chief Executive Officer, and Raymond
C. Lieberenz, Secretary, of Tehama Bancorp, a corporation organized and existing
under the laws of California (hereinafter called the "Corporation"), do hereby
certify as follows:

     1.   On July 22, 1999, the Board of Directors of the Corporation adopted a
resolution designating 30,000 shares of Preferred Stock as Series A Junior
Participating Preferred Stock.

     2.   No shares of Series A Junior Participating Preferred Stock have been
issued.

     3.   Pursuant to the authority conferred upon the Board of Directors by the
Articles of Incorporation of the Corporation, the following resolution was duly
adopted by the Board of Directors on July 22, 1999, creating the series of
Preferred Stock designated as Series A Junior Participating Preferred Stock:

          RESOLVED FURTHER, That the Board of Directors, to implement the
     Rights, pursuant to the authority vested in the Board of Directors of this
     Corporation in accordance with the provisions of its Articles of
     Incorporation, a series of Preferred Stock of the Corporation be and hereby
     is created, and that the determination and amount thereof and the voting
     powers, preferences and relative, participating, optional and other special
     rights of the shares of such series, and the qualifications, limitations or
     restrictions thereof are as follows:

                 "SERIES A JUNIOR PARTICIPATING PREFERRED STOCK"

          Paragraph 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 Thirty Thousand (30,000) 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 Corporation convertible into
     Series A Preferred Stock.

          Paragraph 2. DIVIDENDS AND DISTRIBUTIONS.

          (A) Subject to the rights of the holders of any shares of any series
     of 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,
     no par value (the "Common Stock"), of the Corporation, and of any other
     junior stock, shall be entitled to receive, when, as and if declared by the
     Board of Directors out of funds legally available for the purpose,
     dividends payable in cash (each payment date determined by the Board of
     Directors 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 (subject to the provision for adjustment hereinafter set forth) equal
     to 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 or a subdivision of the outstanding shares of the Common
     Stock (by reclassification or otherwise), 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
     Corporation 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 to which holders of shares of Series A
     Preferred Stock were entitled immediately prior to such event under 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 Corporation shall declare a dividend or distribution on the
     Series A Preferred Stock as provided in paragraph (A) of this Paragraph 2
     immediately after it declares a dividend or distribution on the Common
     Stock (other than a dividend payable in shares of Common Stock).

          (C) 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.

          Paragraph 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,
     each share of Series A Preferred Stock shall entitle the holder thereof to
     100 votes on all matters submitted to a vote of the shareholders of the
     Corporation. In the event the Corporation 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


                                       A-2

<PAGE>

     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 an 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 any other Certificate of
     Amendment to the Articles of Incorporation or Certificate of Determination
     creating a series of Preferred Stock or any similar stock, or by law, the
     holders of shares of Series A Preferred Stock and the holders of shares of
     Common Stock and any other capital stock of the Corporation having general
     voting rights shall vote together as one class on all matters submitted to
     a vote of shareholders of the Corporation.

          (C)  Except as set forth herein, or as otherwise provided by law,
     holders of Series A Preferred Stock shall have no special voting rights and
     their consent shall not be required (except to the extent they are entitled
     to vote with holders of Common Stock as set forth herein) for taking any
     corporate action.

          Paragraph 4.   CERTAIN RESTRICTIONS.

          (A)  Whenever quarterly dividends or other dividends or distributions
     payable on the Series A Preferred Stock as provided in Paragraph 2 are in
     arrears, thereafter and until all accrued and unpaid dividends and
     distributions, whether or not declared, on shares of Series A Preferred
     Stock outstanding shall have been paid in full, the Corporation shall not:

               (i)   declare or pay dividends, or make any other distributions,
                     on any shares of stock ranking junior (either as to
                     dividends or upon liquidation, dissolution or winding up)
                     to the Series A Preferred Stock;

               (ii)  declare or pay dividends, or make any other distributions,
                     on any shares of stock ranking on a parity (either as to
                     dividends or upon liquidation, dissolution or winding up)
                     with the Series A Preferred Stock, except dividends paid
                     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 Corporation may
                     at any time redeem, purchase or otherwise acquire shares of
                     any such junior stock in exchange for shares of any stock

                     any shares of Series A Preferred Stock, or any shares of
                     stock ranking on a parity 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 Corporation shall not permit any subsidiary of the
     Corporation to purchase or otherwise acquire for consideration any shares
     of stock of the Corporation unless the Corporation could, under paragraph
     (A) of this Paragraph 4, purchase or otherwise acquire such shares at such
     time and in such manner.

          Paragraph 5.   REACQUIRED SHARES. Any shares of Series A Preferred
     Stock purchased or otherwise acquired by the Corporation in any manner
     whatsoever shall be retired and canceled promptly after the acquisition
     thereof. All such shares shall upon their cancellation become authorized
     but unissued shares of Preferred Stock and may be reissued as part of a new
     series of Preferred Stock subject to the conditions and restrictions on
     issuance set forth herein, in the Articles of Incorporation, or in any
     other Certificate of Amendment to the Articles of Incorporation or
     Certificate of Determination creating a series of Preferred Stock or any
     similar stock or as otherwise required by law.

          Paragraph 6.   LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any
     liquidation, dissolution or winding up of the Corporation, no distribution
     shall be made (1) to the holders of shares of stock ranking junior (either
     as to dividends or upon 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 a minimum of $100.00 per
     share, plus an amount equal to accrued and unpaid dividends and
     distributions thereon, whether or not declared, 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 (2) to the holders of shares of stock ranking on a parity (either
     as to dividends or 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 Corporation 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 aggregate amount to which holders of shares of
     Series A Preferred Stock were entitled immediately prior to such event
     under the


                                       A-4

<PAGE>



     proviso in clause (1) 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.

          Paragraph 7.   CONSOLIDATION, MERGER, ETC. In case the Corporation
     shall enter into any consolidation, merger, combination or other
     transaction in which the shares of Common Stock are exchanged for or
     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
     Corporation 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.

          Paragraph 8.   NO REDEMPTION. The shares of Series A Preferred Stock
     shall not be redeemable.

          Paragraph 9.   RANK. The Series A Preferred Stock shall rank, with
     respect to the payment of dividends and the distribution of assets, junior
     to all other series of the Corporation's Preferred Stock.

          Paragraph 10.  AMENDMENT. The Articles of Incorporation shall not be
     amended in any manner which would materially alter or change the powers,
     preferences or special rights of the Series A Preferred Stock so as to
     affect them adversely without, in addition to any other vote of
     shareholders required by law, the affirmative vote of the holders of at
     least a majority of the outstanding shares of Series A Preferred Stock,
     voting together as a single class.

          Paragraph 11.  FRACTIONAL SHARES. The Series A Preferred Stock may be
     issued in fractions of a share which shall entitle the holder, in
     proportion to such holder's fractional shares, to exercise voting rights,
     receive dividends, participate in distributions and to have the benefit of
     all other rights of holders of the Series A Preferred Stock."

                                    EXHIBIT C



Dear Shareholder of Tehama Bancorp:

     As part of its overall effort to enhance shareholder value, the Board of
Directors on July 22, 1999, adopted a shareholder rights plan set forth in a
Rights Agreement under which the Company's common shareholders as of the record
date of August 2, 1999, will receive Rights to purchase shares of preferred
stock. My purpose in writing this letter is to describe the Board's reasons for
adopting the Rights Agreement and to briefly explain how the Rights Agreement
works. Please note that this description of the Rights is only a summary and is
qualified in its entirety by reference to the Rights Agreement. A copy of the
Rights Agreement has been filed with the SEC and is available to shareholders
free of charge from the Company.

     The purpose of the Rights Agreement is to provide additional protections to
you as a shareholder of the Company in the event of an unsolicited attempt to
acquire the Company in a manner or on terms that the Board does not believe are
fair to you or in your best interests. The Board believes certain takeover
tactics are a serious potential problem and are not in the best interests of
shareholders. They could deprive the Board of any real opportunity to
participate in the determination of the Company's destiny. Many other companies
have adopted shareholder rights plans to protect shareholders against these
tactics.

     The Board was aware when it adopted the Rights Agreement of arguments that
securities of the sort being issued by the Company may deter legitimate
acquisition proposals. The Board has found no evidence that this has occurred.
The Rights Agreement is not intended to prevent an acquisition of the Company or
substantial investments on terms that are favorable and fair to all
shareholders, and will not do so. It will not interfere with a merger or other
business combination transaction approved by the Board. Its purpose is to
require that a potential acquiring company or person negotiate terms directly
with the Board of Directors.

     The Board did not adopt the Rights Agreement in response to any specific
proposal. However, the Board concluded that the Rights Agreement should be
adopted now so it would be in place to protect your interests in the future.
Issuance of the Rights does not in any way weaken the financial strength of the
Company and has no dilutive effect on the value of YOUR shares, although the
ultimate effect of the Rights, if they are exercised, would be to dilute
substantially the value of shares acquired by an unfriendly or hostile acquiror.
The Rights will only be exercisable if and when a situation arises which they
were created to address. The Rights work in the following manner.

     One Right will be distributed as a dividend on each outstanding share of
common stock to shareholders of record as of the record date of August 2,
1999. Each Right will entitle the registered holder, WHEN AND IF certain
specified takeover activity occurs, to purchase from the Company one
one-hundredth of a share of Series A Junior Participating Preferred Stock, no
par value (the"Preferred Shares"), at a price of $55.00. Under certain
circumstances, the holders of Rights shall have the right to receive common
shares, rather than Preferred Shares, upon the exercise of their Rights.
Generally, each one one-hundredth of a Preferred Share will have the same
economic and voting rights as one share of common stock.

<PAGE>

     Initially, no separate Rights Certificates will be issued. Instead, the
Rights will be attached to all outstanding common stock certificates, including
certificates issued after the record date of the distribution of the Rights,
regardless of whether any such certificate actually indicates that Rights are
attached. The Rights will separate from the common stock if a person or group of
persons acquires or announces that it intends to acquire 10 percent or more of
the outstanding common stock of the Company without Board approval. Such a
person or group of persons is called an "Acquiring Person." After and if any
person or group becomes an Acquiring Person, separate Rights Certificates will
be mailed to shareholders of record of the common stock. After that time, Right
certificates alone will evidence the Rights, and the Rights may be traded and
transferred independently.

     The Rights are not exercisable unless and until there is an Acquiring
Person. If there is an Acquiring Person, all shareholders OTHER THAN THE
ACQUIRING PERSON will have the right to receive upon exercise of a Right the
number of shares of common stock having a market value of two times the
exercise price of the Right. In other words, each Right will allow its holder
to purchase $110 worth of common stock (or equivalent securities) for $55,
unless the holder is an Acquiring Person. The Rights Agreement also has
provisions for forms of cashless exercise of Rights and (at the option of the
Board of Directors) for the direct exchange of Rights for common or preferred
shares at any time after there is an Acquiring Person (but not after any
person other than the Company and its affiliates becomes the owner of 50
percent or more of the Company's shares outstanding). Until exercised, a
Right confers no voting or other shareholder rights. The Rights will expire
on July 31, 2009. The Board may redeem the Rights before then at a price of
$0.001 per Right at any time before a person becomes an Acquiring Person.

     At present, there is no need for shareholders to exchange their share
certificates. Because the Rights are not currently exercisable and will not be
exercisable until there is an Acquiring Person, there is no need for
shareholders to make any decisions regarding the exercise of the Rights or take
other action at this time. Because of the dilutive effect this process would
have on the shares of an Acquiring Person, the Board does not expect that the
Rights will actually separate from the common stock or actually become
exercisable; their deterrent effect on aggressive investors is their primary
purpose.

     In adopting the Rights Agreement, we have expressed our confidence in the
Company's future and our determination that you, as a shareholder, be given
every opportunity to participate fully in that future.

                             /s/ John W. Koeberer

                    ADOPTS SHAREHOLDER PROTECTION RIGHTS PLAN

     Red Bluff, California, July 23, 1999 -- The Board of Directors of Tehama
Bancorp (the "Company") today announced its adoption of a Shareholder
Protection Rights Plan and declaration of a dividend of one Right on each
outstanding share of the Company's Common Stock. The dividend will be paid on
August 31, 1999 to shareholders of record on August 2, 1999.

     The Rights Plan was not adopted in response to any specific effort to
acquire control of the Company. Rather, it was adopted to deter abusive takeover
tactics that can be used to deprive shareholders of the full value of their
investment.

     Until it is announced that a person or group has acquired 10% or more of
the Company's Common Stock (an "Acquiring Person") or commences a tender offer
that will result in such person or group owning 10% or more of the Company's
Common Stock, the Rights will be evidenced by the Common Stock certificates,
will automatically trade with the Common Stock and will not be exercisable.
Thereafter, separate Rights certificates will be distributed and each Right will
entitle its holder to purchase Participating Preferred Stock having economic and
voting terms similar to those of one share of Common Stock for an exercise price
of $55.00.

     Upon announcement that any person or group has become an Acquiring Person,
then 10 days thereafter (or such earlier or later date as the Board may decide)
(the "Flip-in Date") each Right (other than Rights beneficially owned by any
Acquiring Person or transferees thereof, which Rights become void) will entitle
its holder to purchase, for the exercise price, a number of shares of the
Company's Common Stock or Participating Preferred Stock having a market value of
twice the exercise price.

     Also, if after an Acquiring Person controls the Company's Board of
Directors, the Company is involved in a merger or sells more than 50% of its
assets or earning power (or has entered an agreement to do any of the foregoing)
and, in the case of a merger, the Acquiring Person will receive different
treatment than all other shareholders or the Person with whom the merger occurs
is the Acquiring Person or a person affiliated or associated with the Acquiring
Person, each Right will entitle its holder to purchase, for the exercise price,
a number of shares of common stock of the Acquiring Person having a market value
of twice the exercise price. If any person or group acquires between 10% and 50%
of the Company's Common Stock, the Company's Board of Directors may, at its
option, exchange one share of the Company's Common Stock for each Right.

     The Rights may be redeemed by the Board of Directors for $0.001 per Right
prior to the Flip-in Date.

     William P. Ellison, President and Chief Executive Officer of the Company,
stated that "the Rights Plan is not intended to and will not prevent a takeover
of the Company at a full and fair price. However, the Rights may cause
substantial dilution to a person or group that acquires 10% or more of the
Common Stock unless the Rights are first redeemed by the Board of Directors of
the Company. Nevertheless, the Rights should not interfere with a

transaction that is in the best interests of the Company and its shareholders
because the Rights can be redeemed prior to a triggering event."

     "The Rights Plan does not in any way weaken the Company's financial
strength or interfere with its business plans. The issuance of the Rights has no
dilutive effect, will not affect reported earnings per share, is not taxable to
the Company or its shareholders and will not change the way in which the
Company's shares are traded."

     A letter regarding the Rights Plan, with a summary of its provisions, will
be mailed to shareholders.
