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

                  On February 3, 1998 the Board of Directors of Philadelphia
Suburban Corporation (the "Company") declared a dividend distribution of one
right (a "Right") for each outstanding share of Common Stock, $.50 par value
(each, a "Common Share"), of the Company to stockholders of record at the close
of business on March 1, 1998. Each Right entitles the registered holder to
purchase from the Company a unit consisting of one one-thousandth of a share (a
"Unit") of the Series A Junior Participating Preferred Shares, par value $1.00
per share, of the Company (the "Preferred Shares"), or a combination of
securities and assets of equivalent value, at a Purchase Price of $90 per Unit,
subject to adjustment. The description and terms of the Rights are set forth in
a Rights Agreement (the "Rights Agreement") between the Company and ChaseMellon
Shareholder Services, L.L.C., as Rights Agent.

                  Initially, ownership of the Rights will be evidenced by the
Common Share certificates representing shares then outstanding, and no separate
Rights Certificates will be distributed. The Rights will separate from the
Common Shares and a distribution date will occur (the "Distribution Date") upon
the earlier of (i) ten (10) business days following a public announcement that a
person or group of affiliated or associated persons (an "Acquiring Person") has
acquired, or obtained the right to acquire, beneficial ownership of 20% or more
of the outstanding Common Shares (the "Stock Acquisition Date"), or (ii) within
ten (10) business days (or such later date as may be determined by the Board of
Directors prior to such time as any person or group of affiliated or associated
persons becomes an Acquiring Person) following the commencement of a tender
offer or exchange offer that would result in a person or group (excluding the
Company and its subsidiaries and benefit plans) beneficially owning 20% or more
of the outstanding Common Shares. Until the Distribution Date, the Rights will
be evidenced by the Common Share certificates and will be transferred with and
only with such Common Share certificates. Therefore, the surrender for transfer
of any certificates for Common Shares outstanding will also constitute the
transfer of the Rights associated with the Common Shares represented by such
certificate.

                  The Rights are not exercisable until the Distribution Date and
will expire at the close of business on March 1, 2008, unless earlier redeemed
by the Company as described below or unless a transaction under Section 13(d) of
the Rights Agreement has occurred.

         As soon as practicable after the Distribution Date, Rights Certificates
will be mailed to holders of record of the Common Shares as of the close of
business on the Distribution Date and thereafter, the separate Rights
Certificates alone will represent the Rights. Except as otherwise determined by
the Board of Directors, and except in connection with the exercise of employee
stock options or stock appreciation rights or under any other benefit plan for
employees or directors or in connection with the exercise of warrants or
conversion of convertible securities, only Common Shares issued after March 1,
1998 and prior to the Distribution Date will be issued with Rights.




<PAGE>



                  Except in the circumstances described below, after the
Distribution Date each Right will be exercisable into one one-thousandth of a
Preferred Share (a "Preferred Share Fraction"). Each Preferred Share Fraction
carries voting and dividend rights that are intended to produce the equivalent
of one Common Share. The voting and dividend rights of the Preferred Shares are
subject to adjustment in the event of dividends, subdivisions and combinations
with respect to the Common Shares of the Company. In lieu of issuing
certificates for Preferred Share Fractions which are less than an integral
multiple of one Preferred Share (i.e. 1,000 Preferred Share Fractions), the
Company may pay cash representing the current market value of the Preferred
Share Fractions.

                  In the event that at any time following the Stock Acquisition
Date, (i) the Company is the surviving corporation in a merger with an Acquiring
Person and its Common Shares remain outstanding, (ii) a person, including
affiliates and associates, becomes the beneficial owner of more than 20% of the
then outstanding Common Shares (unless such acquisition is made pursuant to a
tender or exchange offer for all outstanding Common Shares upon terms and
conditions determined by at least a majority of the Continuing Directors (as
defined below), after receiving advice from one or more nationally recognized
investment banking firms, to be in the best interests of the Company and its
stockholders (a "Qualifying Offer")), (iii) an Acquiring Person engages in one
or more "self-dealing" transactions, as set forth in the Rights Agreement or
(iv) during such time as there is an Acquiring Person an event occurs that
results in such Acquiring Person's ownership interest being increased by more
than one percent (1%) (e.g., a reverse stock split), each holder of a Right will
thereafter have the right to receive, upon exercise, Common Shares (or, in
certain circumstances, cash, property or other securities of the Company) having
a value equal to approximately two times the exercise price of the Right. In
lieu of requiring payment of the Purchase Price upon exercise of the Rights
following any such event, the Company, by action of a majority of the Continuing
Directors in office at the time, may permit the holders simply to surrender the
Rights, in which event they will be entitled to receive Common Shares (and other
property, as the case may be) with a value of 50% of what could be purchased by
payment of the full Purchase Price. Notwithstanding any of the foregoing,
following the occurrence of any of the events set forth in clauses (i), (ii),
(iii) or (iv) of this paragraph, all Rights that are, or (under certain
circumstances specified in the Rights Agreement) were, beneficially owned by any
Acquiring Person who was involved in the transaction giving rise to any such
event will be null and void. However, Rights are not exercisable following the
occurrence of any of the events set forth above until such time as the Rights
are no longer redeemable by the Company as set forth below.

                  For example, at an exercise price of $90 per Right, each Right
not otherwise voided following an event set forth in the preceding paragraph
would entitle its holder to purchase $180 worth of Common Shares (or other
consideration, as noted above) for $90. Assuming that the Common Shares had a
per share value of $30 at such time, the holder of each valid Right would be
entitled to purchase six Common Shares for $90. Alternatively, the Company could
permit the holder to surrender each Right in exchange for stock equivalent to



<PAGE>



three Common Shares (or cash or other securities with a value of $90) without
the payment of any consideration other than the surrender of the Right.

                  In the event that, at any time following the Stock Acquisition
Date, (i) the Company is acquired in a merger or other business combination
transaction in which the Company is not the surviving corporation (other than a
merger that follows a Qualifying Offer), or (ii) 50% or more of the Company's
assets or earning power is sold or transferred, each holder of a Right (except
Rights that previously have been voided as set forth above) shall thereafter
have the right to receive, upon exercise, common shares of the acquiring company
having a value equal to approximately two times the exercise price of the Right.
Again, provision is made to permit, at the option of the Company, surrender of
the Rights in exchange for one-half of the value otherwise purchasable. The
events set forth in this paragraph and in the second preceding paragraph are
referred to as the "Triggering Events."

                  The Purchase Price payable, and the number of Units of
Preferred Shares or other securities or property issuable upon exercise of the
Rights are subject to adjustment from time to time to prevent dilution (i) in
the event of a stock dividend on, or a subdivision, combination or
reclassification of, the Preferred Shares, (ii) if holders of the Preferred
Shares are granted certain rights or warrants to subscribe for Preferred Shares
or convertible securities at less than the current market price of the Preferred
Shares, or (iii) upon the distribution to holders of the Preferred Shares of
evidences of indebtedness or assets (excluding regular quarterly dividends) or
of subscription rights or warrants (other than those referred to above). Similar
dilution protection exists with respect to transactions affecting Common Shares
similar to those described in clauses (i) - (iii) above.

                  With certain exceptions, no adjustment in the Purchase Price
will be required until cumulative adjustments amount to at least 1% of the
Purchase Price. No fractional Units will be issued and, in lieu thereof, an
adjustment in cash will be made based on the market price of the Preferred
Shares on the last trading date prior to the date of exercise.

                  At any time until ten days following the Stock Acquisition
Date, the Company may redeem the Rights in whole, but not in part, at a price of
$.01 per Right. That ten day redemption period may be extended by the Board of
Directors so long as the Rights are still redeemable. Under certain
circumstances set forth in the Rights Agreement, the decision to redeem will
require the concurrence of a majority of the Continuing Directors (as defined
below). Immediately upon the action of the Board of Directors ordering
redemption of the Rights, with, where required, the concurrence of the
Continuing Directors, the Rights will terminate and the only right of the
holders of Rights will be to receive the $.01 redemption price.

                  The term "Continuing Directors" means any member of the Board
of Directors of the Company who was a member of the Board prior to the date of
the Rights Agreement, and any person who is subsequently elected to the Board if
such person's nomination for election to the Board is recommended or approved by
a majority of the Continuing Directors, but shall not



<PAGE>



include an Acquiring Person, or an affiliate or associate of an Acquiring
Person, or any representative of the foregoing entities.

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

                  Other than those provisions relating to certain principal
economic terms of the Right, any of the provisions of the Rights Agreement may
be amended by the Board of Directors of the Company prior to the Distribution
Date. After the Distribution Date, the provisions of the Rights Agreement may be
amended by the Board (in certain circumstances with the concurrence of a
majority of the Continuing Directors) in order to cure any ambiguity, to make
changes that do not adversely affect the interests of holders of Rights
(excluding the interests of any Acquiring Person), or to shorten or lengthen any
time period under the Rights Agreement; provided, however, that no amendment to
adjust the time period governing redemption shall be made at such time as the
Rights are not redeemable.

                  A copy of the Rights Agreement is being filed with the
Securities and Exchange Commission as an Exhibit to this Registration Statement
on Form 8-A. This summary description of the Rights does not purport to be
complete and is qualified in its entirety by reference to the Rights Agreement,
which is incorporated herein by reference.

                                RIGHTS AGREEMENT

                  RIGHTS AGREEMENT, dated as of March 1, 1998 (the "Agreement"),
between PHILADELPHIA SUBURBAN CORPORATION, a Pennsylvania corporation (the
"Company"), and CHASEMELLON SHAREHOLDER SERVICES, L.L.C., a New Jersey limited
liability company (the "Rights Agent").

                               W I T N E S S E T H

                  WHEREAS, on February 3, 1998 (the "Rights Dividend Declaration
Date"), the Board of Directors of the Company authorized and declared a dividend
distribution of one Right for each Common Share (as hereinafter defined) of the
Company outstanding at the close of business on March 1, 1998 (the "Record
Date") (which for these purposes shall include all Common Shares presently
entitled to receive dividends) and has authorized the issuance of one Right (as
such number may hereafter be adjusted pursuant to the provisions of Section
11(i) hereof) for each Common Share of the Company issued between the Record
Date (whether originally issued or delivered from the Company's treasury) and
the Distribution Date (as hereinafter defined), each Right initially
representing the right to purchase one one-thousandth of a Preferred Share (as
hereinafter defined) of the Company having the rights, powers and preferences
set forth in the form of the Resolution of the Board of Directors attached
hereto as Exhibit A, upon the terms and subject to the conditions hereinafter
set forth (the "Rights"); and

                  WHEREAS, the Rights will be held by the Rights Agent under
this Agreement as trustee for the shareholders of the Company until the
Distribution Date; and

                  WHEREAS, the Board of Directors of the Company has considered
whether approval of this Agreement and the distribution of the Rights is in the
best interests of the Company and all other pertinent factors; and

                  WHEREAS, the Board of Directors of the Company has concluded
that approval of this Agreement and the distribution of the Rights is in the
best interests of the Company because the existence of the Rights will help (i)
reduce the risk of coercive two-tiered, front-end loaded or partial offers that
may not offer fair value to all shareholders, (ii) mitigate against market
accumulators who through open market and/or private purchases may achieve a
position of substantial influence or control without paying to selling or
remaining shareholders a fair control premium, (iii) deter market accumulators
who are simply interested in putting the Company into "play," (iv) restrict
self-dealing by a substantial shareholder, and (v) preserve the Board of
Directors' bargaining power and flexibility to deal with third-party acquirors,
to pursue the business strategies of the Company and to otherwise seek to
maximize values for all shareholders.

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




                                       -1-




<PAGE>



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

                            (a) "Acquiring Person" shall mean any Person who or
which, together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of 20% or more of the Common Shares then outstanding, but shall
not include the Company, any Subsidiary of the Company, any employee benefit
plan of the Company or of any Subsidiary of the Company, or any Person or entity
organized, appointed or established by the Company for or pursuant to the terms
of any such plan. Notwithstanding the foregoing, no Person shall become an
"Acquiring Person" as the result of an acquisition of Common Shares by the
Company which, by reducing the number of Common Shares outstanding, increases
the proportionate number of Common Shares beneficially owned by such Person to
20% or more of the Common Shares then outstanding; provided, however, that if a
Person shall become the Beneficial Owner of 20% or more of the then outstanding
Common Shares by reason of Common Shares purchased by the Company and shall,
after such share purchases by the Company, become the Beneficial Owner of any
additional Common Shares, then such Person shall be deemed to be an "Acquiring
Person." Notwithstanding the foregoing, if a majority of the Continuing
Directors then in office determines in good faith that a Person who would
otherwise be an "Acquiring Person", as defined pursuant to the foregoing
provisions of this paragraph (a), has become such inadvertently, and such Person
divests as promptly as practicable a sufficient number of Common Shares so that
such Person would no longer be an Acquiring Person, as defined pursuant to the
foregoing provisions of this paragraph (a), then such Person shall not be deemed
to be an "Acquiring Person" for purposes of this Agreement.

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

         however, that a Person shall not be deemed the "Beneficial Owner" of,
         or to "beneficially own," any security under this subparagraph (ii) as
         a result of an oral or written agreement, arrangement or understanding
         to vote such security if such agreement, arrangement or understanding:

provided, however, that nothing in this paragraph (c) shall cause a person
engaged in business as an underwriter of securities to be the "Beneficial Owner"
of, or to "beneficially own," any securities acquired through such Person's
participation in good faith in a firm commitment underwriting until the
expiration of forty days after the date of such acquisition.

                  Section 3.  Issue of Rights Certificates.

                            (a) Until the earlier of (i) the Close of Business
on the tenth Business Day after a Stock Acquisition Date involving an Acquiring
Person that has become such in a transaction as to which the Board of Directors
has not made the determination referred to in Section 11(a)(ii)(B) hereof, or
(ii) within ten (10) Business Days (or such later date as may be determined by
action of the Board of Directors prior to such time any Person becomes an
Acquiring Person) after the date that a tender or exchange offer by any Person
(other than the Company, any Subsidiary of the Company, any employee benefit
plan of the Company or of any Subsidiary of the Company, or any Person or entity
organized, appointed or established by the Company for or pursuant to the terms
of any such plan) is first published or sent or given within the meaning of Rule
14d-2(a) of the General Rules and Regulations under the Exchange Act, if upon
consummation thereof, such Person would be the Beneficial Owner of 20% or more
of the Common Shares then outstanding (the earlier of (i) and (ii) being herein
referred to as the "Distribution Date"), (x) beneficial interests in the Rights
will be evidenced (subject to the provisions of paragraph (b) of this Section 3)
by the certificates for the Common Shares registered in the names of the holders
of the Common Shares (which certificates for Common Shares shall be deemed also
to be certificates for beneficial interests in the Rights) and not by separate
certificates, and (y) the Rights and beneficial interests therein will be
transferable only in connection with the transfer of the underlying Common
Shares (including a transfer to the Company). The Company must promptly notify
the Rights Agent of such Distribution Date and request that its transfer agent
provide the Rights Agent with a list of the record holders of the Company's
Common Shares as of the close of business on the Distribution Date. As soon as
practicable after the Rights Agent receives such notice and list, the Rights
Agent will send by first-class, postage prepaid mail, to each record holder of
the 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, one or more rights
certificates, in substantially the form of Exhibit B hereto (the "Rights
Certificates"), evidencing one Right for each Common Share so held, subject to
adjustment as provided herein. In the event that an adjustment in the number of
Rights per Common Share has been made pursuant to Section 11(p) hereof, at the
time of distribution of the Rights Certificates, the Company shall make the
necessary and appropriate rounding adjustments (in accordance with Section 14(a)
hereof) so that Rights Certificates representing only whole numbers of Rights
are distributed and cash is paid in lieu of any fractional Rights. As of and
after the Distribution Date, the Rights will be evidenced solely by such Rights
Certificates.

                            (b) With respect to certificates for the Common
Shares outstanding as of the Record Date, until the Distribution Date, the
registered holders of the Common Shares shall also be the registered holders of
the beneficial interests in the associated Rights. Until the earlier of the
Distribution Date or the Expiration Date (as such term is defined in Section 7
hereof), the

transfer of any certificates representing Common Shares in respect of which
Rights have been issued shall also constitute the transfer of the Rights
associated with such Common Shares. Certificates issued after the Record Date
upon the transfer of Common Shares outstanding on the Record Date shall bear the
legend set forth in subsection (c).

                            (c) Except as provided in Section 22 hereof, Rights
shall be issued in respect of all Common Shares that are issued (whether
originally issued or delivered from the Company's treasury) after the Record
Date but prior to the earlier of the Distribution Date or the Expiration Date.
Certificates representing such Common Shares shall also be deemed to be
certificates for beneficial interests in the associated Rights, and shall bear
the following legend:

                           "This certificate also evidences a beneficial
         interest in and entitles the holder hereof to certain Rights as set
         forth in the Rights Agreement between Philadelphia Suburban Corporation
         (the "Company") and ChaseMellon Shareholder Services, L.L.C. (the
         "Rights Agent") dated as of March 1, 1998 (the "Rights Agreement"), and
         as the same may be amended from time to time, the terms of which are
         hereby incorporated herein by reference and a copy of which is on file
         at the principal offices of the Company. Under certain circumstances,
         as set forth in the Rights Agreement, such Rights will be evidenced by
         separate certificates and beneficial interests therein will no longer
         be evidenced by this certificate. The Company will mail to the holder
         of this certificate a copy of the Rights Agreement, as in effect on the
         date of mailing, without charge promptly after receipt of a written
         request therefor. Under certain circumstances set forth in the Rights
         Agreement, Rights issued to, or held by, any Person who is, was or
         becomes an Acquiring Person or any Affiliate or Associate thereof (as
         such terms are defined in the Rights Agreement), whether currently held
         by or on behalf of such Person or by any subsequent holder, may become
         null and void."

With respect to such certificates containing the foregoing legend, until the
earlier of (i) the Distribution Date or (ii) the Expiration Date, beneficial
interests in the Rights associated with the Common Shares represented by such
certificates shall be evidenced by such certificates alone and registered
holders of Common Shares shall also be the registered holders of beneficial
interests in the associated Rights, and the transfer of any of such certificates
shall also constitute the transfer of beneficial interests in the Rights
associated with the Common Shares represented by such certificates.

                  Section 4.  Form of Rights Certificates.

                            (a) The Rights Certificates (and the forms of
election to purchase and of assignment to be printed on the reverse thereof)
shall each be substantially in the form set forth in Exhibit B hereto and may
have such marks of identification or designation and such legends, summaries or
endorsements printed thereon as the Company may deem appropriate (which do not
affect the duties or responsibilities of the Rights Agent) 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 the Nasdaq Stock
Market on which the Rights may from time to time be listed, or to conform to
usage. Subject to the provisions of Section 11 and Section 22 hereof, the Rights
Certificates, whenever distributed, shall entitle the holders thereof to
purchase such number of Preferred Share Fractions as shall be set forth therein
at the price set forth therein (such exercise price per Preferred Share
Fraction, the "Purchase Price"), but the amount and type of securities
purchasable upon the exercise of each Right and the Purchase Price thereof shall
be subject to adjustment as provided herein.

                            (b) Any Rights Certificate issued pursuant to
Section 3(a) or Section 22 hereof that represents Rights that the Company knows
are beneficially owned by: (i) an Acquiring Person or any Associate or Affiliate
of an Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such
Associate or Affiliate) who becomes a transferee after the Acquiring Person
becomes such, or (iii) a transferee of an Acquiring Person (or of any such
Associate or Affiliate) who becomes a transferee prior to or concurrently with
the Acquiring Person becoming such and receives such Rights pursuant to either
(A) a transfer (whether or not for consideration) from the Acquiring Person to
holders of equity interests in such Acquiring Person or to any Person with whom
such Acquiring Person has any continuing oral or written plan, agreement,
arrangement or understanding regarding the transferred Rights or (B) a transfer
that the Board of Directors of the Company has determined is part of an oral or
written plan, agreement, arrangement or understanding that has as a primary
purpose or effect avoidance of Section 7(e) hereof, and provided that the
Company shall have notified the Rights Agent that this Section 4(b) applies, any
Rights Certificate issued pursuant to Section 6 or Section 11 hereof upon
transfer, exchange, replacement or adjustment of any other Rights Certificate
referred to in this sentence, shall contain (to the extent feasible) the
following legend:

         "The Rights represented by this Rights Certificate are or were
         beneficially owned by a Person who was or became an Acquiring Person or
         an Affiliate or Associate of an Acquiring Person (as such terms are
         defined in the Rights Agreement). Accordingly, this Rights Certificate
         and the Rights represented hereby may



                                       -8-

         become null and void in the circumstances specified in Section 7(e) of 
         such Agreement."

                  Section 5.  Countersignature and Registration.

                            (a) The Rights Certificates shall be executed on
behalf of the Company by its Chairman of the Board, its President or any Vice
President, either manually or by facsimile signature, and shall have affixed
thereto the Company's seal or a facsimile thereof which 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 so countersigned.
In case any officer of the Company who shall have signed any of the 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 Certificates 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.

                            (b) Following the Distribution Date and upon receipt
by the Rights Agent of the notice and list of recordholders of the Rights
referred to in Section 3(a), the Rights Agent will keep or cause to be kept, at
its office or offices designated pursuant to Section 25 hereof, 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, the Certificate number 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.

                            (a) Subject to the provisions of Section 4(b),
Section 7(e) and 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
Expiration Date, any Rights Certificate or Certificates may be transferred,
split up, combined or exchanged for another Rights Certificate or Certificates,
entitling the registered holder to purchase a like number of Preferred Share
Fractions (or, following a Triggering Event, Common Shares or other securities,
cash or other assets, as the case may be), as the Rights Certificate or
Certificates surrendered then entitled such holder or

former holder in the case of a transfer to purchase. Any registered holder
desiring to transfer, split up, combine or exchange any Rights Certificate or
Certificates shall make such request in writing delivered to the Rights Agent,
and shall surrender the Rights Certificate or Certificates to be transferred,
split up, combined or exchanged at the office of the Rights Agent designated for
such purpose. Neither the Rights Agent nor the Company shall be obligated to
take any action whatsoever with respect to the transfer of any such surrendered
Rights Certificate or Certificates until the registered holder shall have
completed and signed the certificate contained in the form of assignment on the
reverse side of such Rights Certificate and shall have provided such additional
evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or
Affiliates or Associates thereof as the Company or the Rights Agent shall
reasonably request. Thereupon the Rights Agent shall, subject to Section 4(b),
Section 7(e) and Section 14 hereof, countersign and deliver to the Person
entitled thereto a Rights Certificate or Rights Certificates, as the case may
be, as so requested. The Rights Agent shall not be obligated to process the
transaction until it has received evidence that all taxes and charges arising
from the transaction have been paid. 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.

                            (b) 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 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 execute and deliver a new Rights Certificate of like
tenor to the Rights Agent for countersignature and delivery to the registered
owner in lieu of the Rights Certificate so lost, stolen, destroyed or mutilated.

                  Section 7. Exercise of Rights; Purchase Price; Expiration Date

Fraction pursuant to the exercise of a Right shall initially be $90, and shall

representing exercisable Rights, with the form of election to purchase and the
certificate duly executed, accompanied by payment, with respect to each Right so
exercised, of the Purchase Price per Preferred Share Fraction (or Common Shares,
other securities, cash or other assets, as the case may be) to be purchased as
set forth below and an amount equal to any applicable tax or governmental
charge, the Rights Agent shall, subject to Section 20(k) and Section 14(b)
hereof, thereupon promptly (i) (A) requisition from any transfer agent of the
Preferred Shares (or make available, if the Rights Agent is the transfer agent
for the Common Shares) certificates for the total number of Preferred Shares to
be purchased and the Company hereby irrevocably authorizes its transfer agent to
comply with all such requests, or (B) if the Company shall have elected to
deposit some or all of the total number of Preferred Shares issuable upon
exercise of the Rights hereunder with a depositary agent, requisition from the
depositary agent depositary receipts representing such number of Preferred Share
Fractions as are to be purchased (in which case certificates for the Preferred
Shares represented by such receipts shall be deposited by the transfer agent
with the depositary agent) and the Company will direct the depositary agent to
comply with such request, (ii) requisition from the Company the amount of cash,
if any, to be paid in lieu of fractional shares in accordance with Section 14
hereof, (iii) after receipt of such certificates or depositary receipts, cause

Rights Certificate, registered in such name or names as may be designated by
such holder, and (iv) after receipt thereof, deliver such cash, if any, to or
upon the order of the registered holder of such Rights Certificate. The payment
of the Purchase Price (as such amount may be reduced pursuant to Section
11(a)(iii) hereof) may be made, at the election of the holder of the Rights
Certificate, (x) in cash or by certified bank check or money order payable to
the order of the Company or (y) by delivery of Rights if and to the extent
authorized by Section 11(q) hereof. In the event that the Company is obligated
to issue other securities of the Company (including Common Shares) pay cash
and/or distribute other property pursuant to Section 11(a) hereof, the Company
will make all arrangements necessary so that such other securities, cash and/or
other property are available for distribution by the Rights Agent, if and when
necessary to comply with this agreement.

                            (d) In case the registered holder of any Rights
Certificate shall exercise less than all the Rights evidenced thereby, a new

unexercised shall be issued by the Rights Agent and delivered to, or upon the
order of, the registered holder of such Rights Certificate, registered in such
name or names as may be designated by such holder, subject to the provisions of
Section 6 and Section 14 hereof.

                            (e) Notwithstanding anything in this Agreement to
the contrary, from and after the first occurrence of a Section 11(a)(ii) Event,
any Rights beneficially owned by (i) an Acquiring Person or an Associate or
Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or
of any such Associate or Affiliate) who becomes a transferee after the Acquiring
Person becomes such, or (iii) a transferee of an Acquiring Person (or of any
such Associate or Affiliate) who becomes a transferee prior to or concurrently
with the Acquiring Person becoming such and receives such Rights pursuant to
either (A) a transfer (whether or not for consideration) from the Acquiring
Person to holders of equity interests in such Acquiring Person or to any Person
with whom the Acquiring Person has any continuing oral or written plan,
agreement, arrangement or understanding regarding the transferred Rights or (B)
a transfer which the Board of Directors of the Company has determined is part of
an oral or written plan, agreement, arrangement or understanding which has as a
primary purpose or effect the avoidance of this Section 7(e), shall become null
and void without any further action and no holder of such Rights shall have any
rights whatsoever with respect to such Rights, whether under any provision of
this Agreement or otherwise; provided, however, that the Rights held by an
Acquiring Person, an Affiliate or Associate of an Acquiring Person or the
transferees of such persons referred to above shall not be voided unless the
Acquiring Person in question or an Affiliate or Associate of such Acquiring
Person shall be involved in the transaction giving rise to the Section 11(a)(ii)
Event. The Company shall notify the Rights Agent when this Section 7(e) applies
and shall use all reasonable efforts to insure that the provisions of this
Section 7(e) and Section 4(b) hereof are complied with, but neither the Company
nor the Rights Agent shall have any liability to any holder of Rights
Certificates or other Person as a result of the Company's failure to make any
determinations with respect to an Acquiring Person or its Affiliates, Associates
or transferees hereunder.

                            (f) Notwithstanding anything in this Agreement to
the contrary, neither the Rights Agent nor the Company shall be obligated to
undertake any action with respect to a registered holder upon the occurrence of
any purported exercise as set forth in this Section 7 unless such registered
holder shall have (i) properly completed and signed the certificate contained in
the form of election to purchase set forth on the reverse side of the Rights
Certificate surrendered for such exercise, and (ii) provided such additional
evidence of the



                                                   -12-

identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Company shall or the Rights Agent reasonably request.

                  Section 8. Cancellation and Destruction of Rights
Certificates. All Rights Certificates surrendered for the purpose of exercise,
transfer, split up, combination or exchange shall, if surrendered to the Company
or any of its agents, be delivered to the Rights Agent for cancellation or in
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. Reservation and Availability of Capital Stock;
Registration of Securities.

                            (a) The Company covenants and agrees that it will
cause to be reserved and kept available for issuance upon the exercise of
outstanding Rights as many of its authorized and unissued Preferred Shares (and,
following the occurrence of a Triggering Event, out of its authorized and
unissued or treasury Common Shares and/or other securities) or out of its
authorized and issued shares held in its treasury, which together, shall at all
times after the Distribution Date be sufficient to permit the exercise in full
of all outstanding Rights.

                            (b) So long as the Preferred Shares (and, following
the occurrence of a Triggering Event, Common Shares or other securities)
issuable and deliverable upon the exercise of the Rights may be listed on any
stock exchange, or quoted on the Nasdaq Stock Market, the Company shall use its
best efforts to cause, from and after such time as the Rights become
exercisable, all shares and other securities reserved for such issuance to be
listed on such exchange upon official notice of issuance upon such exercise.

                            (c) The Company shall use its best efforts to (i)
file, as soon as practicable following the earliest date after the first
occurrence of a Section 11(a)(ii) Event on which the consideration to be
delivered by the Company upon exercise of the Rights has been determined in
accordance with Section 11(a)(iii) hereof, or as soon as is required by law
following the Distribution Date, as the case may be, a registration statement or
statements under the Securities Act of 1933, as amended (the "Act"), with
respect to the securities purchasable upon exercise of the Rights on an
appropriate form or forms, (ii) cause such registration statement or statements
to



                                      -13-




<PAGE>



become effective as soon as practicable after such filing, and (iii) cause such
registration statement or statements to remain effective (with a prospectus at
all times meeting the requirements of the Act) until the earlier of (A) the date
as of which the Rights are no longer exercisable for such securities, and (B)
the Expiration Date. The Company will also take such action as may be
appropriate under, or to ensure compliance with, the securities or "blue sky"
laws of the various states in connection with the exercisability of the Rights.
The Company may temporarily suspend, for a period of time not to exceed ninety
(90) days after the date set forth in clause (i) of the first sentence of this
subsection (c), the exercisability of the Rights in order to prepare and file
such registration statement and permit it to become effective. Upon any such
suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement at such time as the suspension is no longer in effect. In addition,
if the Company shall determine that a registration statement is required
following the Distribution Date, the Company may, by issuing a public
announcement, temporarily suspend the exercisability of the Rights until such
time as a registration statement has been declared effective. The Company shall
notify the Rights Agent whenever it makes a public announcement pursuant to this
subsection (c) and give the Rights Agent a copy of the announcement.
Notwithstanding any provision of this Agreement to the contrary, the Rights
shall not be exercisable in any jurisdiction unless the requisite qualification
in such jurisdiction shall have been obtained, nor shall the Rights be
exercisable if the exercise thereof shall not be permitted under applicable law
or a registration statement shall not have been declared effective.

                            (d) The Company covenants and agrees that it will
take all such action as may be necessary to ensure that all Preferred Shares
(and, following a Triggering Event, Common Shares or other securities) delivered
upon exercise of Rights shall, at the time of delivery of the certificates for
such shares or other securities (subject to payment of the Purchase Price), be
duly and validly authorized and issued and, with respect to Preferred Shares,
Common Shares or other shares of capital stock, fully paid and nonassessable.

                            (e) The Company further covenants and agrees that it
will pay when due and payable any and all taxes and governmental charges that
may be payable in respect of the issuance or delivery of the Rights Certificates
and of any certificates for a number of Preferred Share Fractions (or Common
Shares or other securities, as the case may be) upon the exercise of Rights. The
Company shall not, however, be required to pay any transfer tax that may be
payable in respect of any transfer or delivery of Rights Certificates to a
Person other than, or the issuance or delivery of a number of Preferred Share
Fractions (or Common Shares or other securities, as the case may be) in respect
of a name other than that of the registered holder of the Rights Certificates
evidencing Rights surrendered for exercise or to issue or deliver any
certificates for a number of Preferred Share Fractions (or Common Shares or
other securities, as



                                      -14-




<PAGE>



the case may be) in a name other than that of the registered holder upon the
exercise of any Rights until such tax shall have been paid (any such tax being
payable by the holder of such Rights Certificate at the time of surrender) or
until it has been established to the Company's satisfaction that no such tax is
due.

                  Section 10. Capital Stock Record Date. Each Person in whose
name any certificate for a number of Preferred Share Fractions (or Common Shares
or other securities, as the case may be) is issued upon the exercise of Rights
shall for all purposes be deemed to have become the holder of record of such
Preferred Share Fractions (or Common Shares or other securities, as the case may
be) 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 all applicable taxes and governmental
charges) was made; provided, however, that if the date of such surrender and
payment is a date upon which the applicable transfer books of the Company are
closed, such Person shall be deemed to have become the record holder of such
shares (fractional or otherwise) on, and such certificate shall be dated, the
next succeeding Business Day on which the applicable 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
shareholder of the Company with respect to shares for which the Rights shall be
exercisable, including, without limitation, the right to vote, to receive
dividends or other distributions or to exercise any preemptive rights, and shall
not be entitled to receive any notice of any proceedings of the Company, except
as provided herein.

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

                           (a) (i) In the event the Company shall at any time
         after the date of this Agreement (A) declare a dividend on any security
         of the Company payable in Preferred Shares, (B) subdivide the
         outstanding Preferred Shares, (C) combine the outstanding Preferred
         Shares into a smaller number of 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) and Section 7(e)
         hereof, 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 Preferred Shares or
         capital stock, as the case may be, issuable on such date, shall be
         proportionately adjusted so that the holder of any Right exercised
         after such time shall be entitled to receive, upon payment of the
         adjusted Purchase Price, the aggregate



                                      -15-




<PAGE>



         number and kind of Preferred Shares or capital stock, as the case may
         be, that, if such Right had been exercised immediately prior to such
         date and at a time when the Preferred Share transfer books were open,
         such holder would have owned upon such exercise and been entitled to
         receive by virtue of such dividend, subdivision, combination or
         reclassification. If an event occurs which would require an adjustment
         under both this Section 11(a)(i) and Section 11(a)(ii) hereof, the
         adjustment provided for in this Section 11(a)(i) shall be in addition
         to, and shall be made prior to, any adjustment required pursuant to
         Section 11(a)(ii) hereof.

                           (ii) In the event:

                                    (A) any Acquiring Person or any Associate or
                  Affiliate of any Acquiring Person, at any time after the Stock
                  Acquisition Date, directly or indirectly, (1) shall merge into
                  the Company or otherwise combine with the Company and the
                  Company shall be the continuing or surviving corporation of
                  such merger or combination and the Common Shares of the
                  Company or other equity securities of the Company shall remain
                  outstanding, (2) shall, in one transaction or a series of
                  transactions, transfer any assets to the Company or to any of
                  its Subsidiaries in exchange (in whole or in part) for Common
                  Shares, for shares of other equity securities of the Company,
                  or for securities exercisable for or convertible into shares
                  of equity securities of the Company (Common Shares or
                  otherwise) or otherwise obtain from the Company, with or
                  without consideration, any additional shares of such equity
                  securities or securities exercisable for or convertible into
                  shares of such equity securities (other than pursuant to a pro
                  rata distribution to all holders of Common Shares), (3) shall
                  sell, purchase, lease, exchange, mortgage, pledge, transfer or
                  otherwise acquire or dispose of assets in one transaction or a
                  series of transactions, to, from or with (as the case may be)
                  the Company or any of its Subsidiaries, on terms and
                  conditions less favorable to the Company than the Company
                  would be able to obtain in arm's-length negotiation with an
                  unaffiliated third party, other than pursuant to a Section 13
                  Event, (4) shall sell, purchase, lease, exchange, mortgage,
                  pledge, transfer or otherwise dispose of assets having an
                  aggregate fair market value of more than $5,000,000 in one
                  transaction or a series of transactions, to, from or with (as
                  the case may be) the Company or any of the Company's
                  Subsidiaries (other than incidental to the lines of business,
                  if any, engaged in as of the date hereof between the Company
                  and such Acquiring Person or Associate or Affiliate), other
                  than pursuant to a Section 13 Event, (5) shall receive any
                  compensation from the Company or any of the Company's
                  Subsidiaries other than compensation for full-time employment
                  as a regular employee at rates in accordance with the



                                      -16-




<PAGE>



                  Company's (or its Subsidiaries') past practices, or (6) shall
                  receive the benefit, directly or indirectly (except
                  proportionately as a shareholder and except if resulting from
                  a requirement of law or governmental regulation), of any
                  loans, advances, guarantees, pledges or other financial
                  assistance or any tax credits or other tax advantages provided
                  by the Company or any of its Subsidiaries; or

                                    (B) any Person (other than the Company, any
                  Subsidiary of the Company, any employee benefit plan of the
                  Company or of any Subsidiary of the Company, or any Person or
                  entity organized, appointed or established by the Company for
                  or pursuant to the terms of any such plan), alone or together
                  with its Affiliates and Associates, shall, at any time after
                  the Rights Dividend Declaration Date, become the Beneficial
                  Owner of 20% or more of the Common Shares then outstanding,
                  unless the event causing the 20% threshold to be crossed is a
                  Section 13 Event, or is an acquisition of Common Shares
                  pursuant to a tender offer or an exchange offer for all
                  outstanding Common Shares at a price and on terms determined
                  by at least a majority of the Continuing Directors, after
                  receiving advice from one or more nationally recognized
                  investment banking firms, to be in the best interests of the
                  Company and its shareholders (a "Qualifying Offer"), after
                  taking into consideration all factors that such members of the
                  Board of Directors deem relevant, including, without
                  limitation, the long-term prospects and value of the Company
                  and the prices and terms that such members of the Board of
                  Directors believe, in good faith, could reasonably be achieved
                  if the Company or its assets were sold on an orderly basis
                  designed to realize maximum value, or

                                    (C) during such time as there is an
                  Acquiring Person, there shall be any reclassification of
                  securities (including any reverse stock split), or
                  recapitalization of the Company, or any merger or
                  consolidation of the Company with any of its Subsidiaries or
                  any other transaction or series of transactions involving the
                  Company or any of its Subsidiaries, other than a Section 13
                  Event or series of such Section 13 Events (whether or not with
                  or into or otherwise involving an Acquiring Person) that 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 that is directly or indirectly beneficially owned
                  by any Acquiring Person or any Associate or Affiliate of any
                  Acquiring Person,

         then, promptly following the first occurrence of a Section 11(a)(ii)
         Event, proper provision shall be made so that each holder of a Right
         (except as provided below and in



                                      -17-




<PAGE>



         Section 7(e) hereof) shall thereafter have the right to receive, upon
         exercise thereof at the then current Purchase Price in accordance with
         the terms of this Agreement, in lieu of a number of Preferred Share
         Fractions, such number of Common Shares of the Company as shall equal
         the result obtained by (x) multiplying the then current Purchase Price
         by the then number of Preferred Share Fractions for which a Right was
         exercisable immediately prior to the first occurrence of a Section
         11(a)(ii) Event, and (y) dividing that product (which, following such
         first occurrence, shall thereafter be referred to as the "Purchase
         Price" for each Right and for all purposes of this Agreement) by 50% of
         the current market price (as defined in and determined pursuant to
         Section 11(d) hereof) per Common Share on the date of such first
         occurrence (such number of shares, the "Adjustment Shares").

                           (iii) In the event that the number of Common Shares
         that are authorized by the Company's Articles of Incorporation but not
         outstanding or reserved for issuance for purposes other than upon
         exercise of the Rights are not sufficient to permit the exercise in
         full of the Rights in accordance with the foregoing subparagraph (ii)
         of this Section 11(a), the Company shall: (A) determine the excess of
         the value of the Adjustment Shares issuable upon the exercise of a
         Right (the "Current Value") over the Purchase Price (such excess, the
         "Spread"), and (B) with respect to each Right, make adequate provision
         to substitute for the Adjustment Shares, upon payment of the applicable
         Purchase Price, (1) cash, (2) a reduction in the Purchase Price, (3)
         Common Shares of the same or a different class or other equity
         securities of the Company (including, without limitation, preferred
         shares or units of preferred shares that a majority of the Continuing
         Directors in office at the time has deemed (based, among other things,
         on the dividend and liquidation rights of such preferred shares) to
         have substantially the same economic value as Common Shares (such
         preferred shares, hereinafter referred to as "common share
         equivalents")), (4) debt securities of the Company, (5) other assets,
         or (6) any combination of the foregoing, having an aggregate value
         equal to the Current Value, where such aggregate value has been
         determined by a majority of the Continuing Directors in office at the
         time after considering the advice of a nationally recognized investment
         banking firm selected by the Board of Directors of the Company;
         provided, however, if the Company shall not have made adequate
         provision to deliver value pursuant to clause (B) above within thirty
         (30) days following the later of (x) the first occurrence of a Section
         11(a)(ii) Event and (y) the date on which the Company's right of
         redemption pursuant to Section 23(a) expires (the later of (x) and (y)
         being referred to herein as the "Section 11(a)(ii) Trigger Date"), 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 available) and then, if necessary,
         cash, which shares and/or cash have an aggregate value equal to the
         Spread. If the Board of Directors of the Company shall determine in
         good



                                      -18-




<PAGE>



         faith that it is likely that sufficient additional Common Shares could
         be authorized for issuance upon exercise in full of the Rights, the
         thirty (30) day period set forth above may be extended to the extent
         necessary, but not more than ninety (90) days after the Section
         11(a)(ii) Trigger Date, in order that the Company may seek shareholder
         approval for the authorization of such additional shares (such period,
         as it may be extended, the "Substitution Period"). To the extent that
         the Company determines that some action need be taken pursuant to the
         first and/or second sentences of this Section 11(a)(iii), the Company
         shall provide, subject to Section 7(e) hereof, that such action shall
         apply uniformly to all outstanding Rights, and 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. The Company
         shall make a public announcement when the exercisability of the Rights
         has been temporarily suspended, and again when such suspension is no
         longer in effect. The Company shall notify the Rights Agent of the
         suspension of the exercisability of the Rights, and provide the Rights
         Agent with a copy of such public announcement. For purposes of this
         Section 11(a)(iii), the value of the Common Shares shall be the current
         market price (as determined pursuant to Section 11(d) hereof) per
         Common Share on the Section 11(a)(ii) Trigger Date and the value of any
         "common share equivalent" shall be deemed to have the same value as the
         Common Shares on such date.

                            (b) In case the Company shall fix a record date for
the issuance of rights, options or warrants to holders of any security of the
Company entitling them to subscribe for or purchase (for a period expiring
within forty-five (45) calendar days after such record date) 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 per
equivalent preferred share (or having a conversion price per share, if a
security convertible into Preferred Shares or equivalent preferred shares) less
than the current market price (as determined pursuant to Section 11(d) hereof)
per Preferred Share 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 that 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



                                      -19-

may be paid by delivery of consideration part or all of which may be in a form
other than cash, the value of such consideration shall be as determined in good
faith by the Board of Directors of the Company, whose determination shall be
described in a statement filed with the Rights Agent and shall be binding on the
Company, the Rights Agent and the holders of the Rights. Preferred Shares owned
by or held for the account of the Company shall not be deemed outstanding for
the purpose of any such computation. Such adjustment shall be made successively
whenever such a record date is fixed, and in the event that such rights or
warrants are not so issued, the Purchase Price shall be adjusted to be the
Purchase Price that would then be in effect if such record date had not been
fixed.

                            (c) In case the Company shall fix a record date for
a distribution to all holders of Preferred Shares (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing corporation) of evidences of indebtedness, cash (other
than a regular quarterly dividend out of the earnings or retained earnings of
the Company), assets (other than a regular quarterly dividend referred to above
or dividend payable in Preferred Shares, but including any dividend payable in
stock other than 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 current market price (as determined pursuant to Section 11(d)
hereof) per Preferred Share on such record date, less the then 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 and
shall be conclusive for all purposes) of the portion of the cash, assets or
evidences of indebtedness so to be distributed or of such subscription rights or
warrants applicable to a Preferred Share and the denominator of which shall be
such current market price (as determined pursuant to Section 11(d) hereof) per
Preferred Share. Such adjustments shall be made successively whenever such a
record date is fixed, and in the event that such distribution is not so made,
the Purchase Price shall be adjusted to be the Purchase Price which would have
been in effect if such record date had not been fixed.

                           (d) (i) For the purpose of any computation hereunder,
         other than computations made pursuant to Section 11(a)(iii) hereof, the
         "current market price" per Common Share on any date shall be deemed to
         be the average of the daily closing prices per Common Share for the
         thirty (30) consecutive Trading Days (as such term is hereinafter
         defined) immediately prior to and not including such date, and for
         purposes of computations made pursuant to Section 11(a)(iii) hereof,
         the "current market price" per Common Share on any date shall be deemed
         to be the average of the daily closing prices per Common Share for the
         ten (10) consecutive Trading Days immediately following and not
         including such date; provided, however, that in the event that the
         current market price



                                      -20-




<PAGE>



         per Common Share is determined during a period following the
         announcement by the issuer of such Common Share of (A) a dividend or
         distribution on such Common Share payable in Common Shares or
         securities convertible into Common Shares (other than the Rights), or
         (B) any subdivision, combination or reclassification of such Common
         Shares, and prior to the expiration of the requisite thirty (30)
         Trading Day or ten (10) Trading Day period, as set forth above, 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 market price" shall be properly
         adjusted to take into account ex-dividend trading. The closing price
         for each Trading Day shall be the last sale price, regular way, or, in
         case no such sale takes place on such day, the average of the closing
         bid and asked prices, regular way, in either case as reported in the
         principal consolidated transaction reporting system with respect to
         securities listed or admitted to trading on the New York Stock Exchange
         or, if the Common Shares 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 Common Shares are
         listed or admitted to trading or, if the Common Shares are not listed
         or admitted to trading on any national securities exchange, the last
         quoted price or, if not so quoted, the average of the high bid and low
         asked prices in the over-the-counter market, as reported by the
         National Association of Securities Dealers, Inc. Automated Quotation
         System ("Nasdaq") or such other system then in use, or, if on any such
         date the Common Shares 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 Common Shares selected
         by the Board of Directors of the Company. If on any such date no market
         maker is making a market in the Common Shares, the fair value of such
         shares 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 Common Shares are listed or admitted to trading is open for the
         transaction of business or, if the Common Shares are not listed or
         admitted to trading on any national securities exchange, a Business
         Day. If the Common Shares are not publicly held or not so listed or
         traded, "current market price" per share shall mean the fair value per
         share as determined in good faith by the Board of Directors of the
         Company, whose determination shall be described in a statement filed
         with the Rights Agent and shall be conclusive for all purposes.

                           (ii) For the purpose of any computation hereunder,
         the "current market price" per Preferred Share shall be determined in
         the same manner as set forth above for the Common Shares in clause (i)
         of this Section 11(d) (other than the last sentence thereof). If the
         current market price per Preferred Share cannot be determined in the



                                      -21-




<PAGE>



         manner provided above or if the Preferred Shares are not publicly held
         or listed or traded in a manner described in clause (i) of this Section
         11(d), the "current market price" per Preferred Share shall be
         conclusively deemed to be an amount equal to one hundred (as such
         number may be appropriately adjusted for such events as stock splits,
         stock dividends and recapitalizations with respect to the Common Shares
         occurring after the date of this Agreement) multiplied by the current
         market price per Common Share. If neither the Common Shares nor the
         Preferred Shares are publicly held or so listed or traded, "current
         market price" per Preferred Share 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 and shall be conclusive for all purposes. For all purposes
         of this Agreement, the "current market price" of a Preferred Share
         Fraction shall be equal to the "current market price" of one Preferred
         Share divided by 1000.

                            (e) Anything herein to the contrary notwithstanding,
no adjustment in the Purchase Price shall be required unless such adjustment
would require an increase or decrease of at least one percent (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 ten-thousandth of a
Common Share or one millionth of a Preferred Share, as the case may be.
Notwithstanding the first sentence of this subsection (e), any adjustment
required by this Section 11 shall be made no later than the earlier of (i) three
(3) years from the date of the transaction that mandates such adjustment, or
(ii) the Expiration Date.

                            (f) If as a result of an adjustment made pursuant to
Section 11(a)(ii) or Section 13(a) hereof, the holder of any Right thereafter
exercised shall become entitled to receive any shares of capital stock other
than Preferred Shares, thereafter the number of such other shares so receivable
upon exercise of any Right and the Purchase Price thereof shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to the Preferred Shares contained in
Sections 11(a), (b), (c), (e), (g), (h), (i), (j), (k), (m) and (q), and the
provisions of Sections 7, 9, 10, 13 and 14 hereof 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 Preferred
Share Fractions purchasable from time to time hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

                            (h) Unless the Company shall have exercised its
election as provided in Section 11(i), upon each adjustment of the Purchase
Price as a result of the calculations made in subsections (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 Preferred Share Fractions (calculated to the nearest one-one millionth
of a Preferred Share) obtained by (i) multiplying (x) the number of Preferred
Share Fractions covered by a Right immediately prior to this adjustment, by (y)
the Purchase Price in effect immediately prior to such adjustment of the
Purchase Price, and (ii) dividing the product so obtained by the Purchase Price
in effect immediately after such adjustment of the Purchase Price.

                            (i) The Company may elect on or after the date of
any adjustment of the Purchase Price to adjust the number of Rights, in lieu of
any adjustment in the number of Preferred Share Fractions purchasable upon the
exercise of a Right. Each of the Rights outstanding after the adjustment in the
number of Rights shall be exercisable for the number of Preferred Share
Fractions 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
millionth of a Preferred Share) 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. The Company shall forward a copy of such
public announcement to the Rights Agent. The record date for the adjustment may
be the date on which the Purchase Price is adjusted or any day thereafter, but,
if the Rights Certificates have been issued, shall be at least ten (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 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 may bear, at the option of the Company, the adjusted Purchase
Price) and shall be registered in the names of the holders of record of Rights
Certificates on the record date specified in the public announcement.




                                                   -23-

                            (j) Irrespective of any adjustment or change in the
Purchase Price or the number of Preferred Share Fractions issuable upon the
exercise of the Rights, the Rights Certificates theretofore and thereafter
issued may continue to express the Purchase Price per Preferred Share Fraction
and the number of Preferred Share Fractions 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 the then stated or par value, if
any, of the number of Preferred Share Fractions issuable upon exercise of the
Rights, the Company shall take any corporate action that may, in the opinion of
its counsel, be necessary in order that the Company may validly and legally
issue such number of fully paid and nonassessable Preferred Share Fractions at
such adjusted Purchase Price.

                            (l) In any case in which this Section 11 shall
require that an adjustment in the Purchase Price be made effective as of a
record date for a specified event, the Company may elect to defer until the
occurrence of such event the issuance to the holder of any Right exercised after
such record date the number of Preferred Share Fractions and other capital stock
or securities of the Company, if any, issuable upon such exercise over and above
the number of Preferred Share Fractions 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 (fractional or
otherwise) or securities upon the occurrence of the event requiring such
adjustment, and the Company shall also deliver a copy of such bill or instrument
to the Rights Agent.

                            (m) Anything in this Section 11 to the contrary
notwithstanding, the Company shall be entitled to make such reductions in the
Purchase Price, in addition to those adjustments expressly required by this
Section 11, as and to the extent that in their good faith judgment the Board of
Directors of the Company shall determine to be advisable in order that any (i)
consolidation or subdivision of the Preferred Shares, (ii) issuance wholly for
cash of any Preferred Shares at less than the current market price, (iii)
issuance wholly for cash for Preferred Shares or securities which by their terms
are convertible into or exchangeable for Preferred Shares, (iv) stock dividends
or (v) issuance of rights, options or warrants referred to in this Section 11,
hereafter made by the Company to holders of its Preferred 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 any other
Person (other than a Subsidiary of the Company in a transaction which complies
with Section 11(o) hereof), (ii) merge with or into any



                                                   -24-




<PAGE>



other Person (other than a Subsidiary of the Company in a transaction which
complies with Section 11(o) hereof), or (iii) sell or transfer (or permit any
Subsidiary to sell or transfer), in one transaction, or a series of related
transactions, assets or earning power aggregating more than 50% of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to any
other person or persons (other than the Company and/or any of its Subsidiaries
in one or more transactions each of which complies with Section 11(o) hereof),
if (x) at the time of or immediately after such consolidation, merger or sale
there are any rights, warrants or other instruments or securities outstanding or
agreements in effect that would substantially diminish or otherwise eliminate
the benefits intended to be afforded by the Rights or (y) prior to,
simultaneously with or immediately after such consolidation, merger or sale, the
shareholders of the Person who constitutes, or would constitute, the "Principal
Party" for purposes of Section 13(a) hereof shall have received a distribution
of Rights previously owned by such Person or any of its Affiliates and
Associates.

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

                            (p) Anything in this Agreement to the contrary
notwithstanding, in the event that the Company shall at any time after the
Rights Dividend Declaration Date and prior to the Distribution Date (i) declare
a dividend on the outstanding Common Shares payable in Common Shares, (ii)
subdivide the outstanding Common Shares, or (iii) combine the outstanding Common
Shares into a smaller number of shares, the number of Rights associated with
each Common Share then outstanding, or issued or delivered thereafter but prior
to the Distribution Date, shall be proportionately adjusted so that the number
of Rights thereafter associated with each Common Share following any such event
shall equal the result obtained by multiplying the number of Rights associated
with each Common Share immediately prior to such event by a fraction the
numerator of which shall be the total number of Common Shares outstanding
immediately prior to the occurrence of the event and the denominator of which
shall be the total number of Common Shares outstanding immediately following the
occurrence of such event.

                            (q) In the event that the Rights become exercisable
following a Section 11(a)(ii) Event, the Company, by action of a majority of the
Continuing Directors in office at the time, may authorize that the Rights,
subject to Section 7(e) hereof, either (i) will only be, or (ii) may, at the
option of the holder entitled to exercise the Rights be, exercisable for, in
either case 50% of the Common Shares (or cash or other securities or assets to
be substituted for the Adjustment Shares pursuant to subsection (a)(iii)) that
would otherwise be purchasable under



                                                   -25-

subsection (a), in consideration of the surrender to the Company of the Rights
so exercised and without other payment of the Purchase Price. Rights exercised
under this subsection (q) shall be deemed to have been exercised in full and
shall be canceled.

                  Section 12. Certificate of Adjusted Purchase Price or Number
of Shares. Whenever an adjustment is made as provided in Section 11 or Section
13 hereof, the Company shall (a) promptly prepare a certificate setting forth
such adjustment and a brief, reasonably detailed statement of the facts and
computations accounting for such adjustment, (b) promptly file with the Rights
Agent, and with each transfer agent for the Preferred Shares and the Common
Shares, a copy of such certificate, and (c) mail a brief summary thereof to each
holder of a Rights Certificate (or, if prior to the Distribution Date, to each
holder of a certificate representing Common Shares) in accordance with Section
25 hereof. The Rights Agent shall be fully protected in relying on any such
certificate and on any adjustment therein contained and shall have no duty with
respect to and shall not be deemed to have knowledge of any such adjustment
unless and until it shall have received such a certificate.

                  Section 13. Consolidation, Merger or Sale or Transfer of
Assets or Earning Power.

                            (a) In the event that, following the Stock
Acquisition Date, directly or indirectly, (x) the Company shall consolidate
with, or merge with and into, any other Person (other than a Subsidiary of the
Company in a transaction which complies with Section 11(o) hereof), and the
Company shall not be the continuing or surviving corporation of such
consolidation or merger, (y) any person (other than a Subsidiary of the Company
in a transaction which complies with Section 11(o) hereof) shall consolidate
with, or merge with or into, the Company, and the Company shall be the
continuing or surviving corporation of such consolidation or merger and, in
connection with such consolidation or merger, all or part of the outstanding
Common Shares shall be changed into or exchanged for stock or other securities
of any other Person or cash or any other property, or (z) the Company shall sell
or otherwise transfer (or one or more of its Subsidiaries shall sell or
otherwise transfer), in one transaction or a series of related transactions,
assets or earning power aggregating more than 50% of the assets, operating
income, cash flow or earning power of the Company and its Subsidiaries (taken as
a whole) to any Person or Persons (other than the Company or any Subsidiary of
the Company in one or more transactions each of which complies with Section
11(o) hereof), then, and in each such case and except as contemplated by
subsection (d), proper provision shall be made so that:

                                    (i) each holder of a Right, except as
         provided in Section 7(e) hereof or subsection (e), shall thereafter
         have the right to receive, upon the exercise thereof at the then
         current Purchase Price in accordance with the terms of this Agreement,
         such number of validly authorized and issued, fully paid, non
         assessable and freely tradeable Common



                                                   -26-

         Shares of the Principal Party (as such term is hereinafter defined),
         not subject to any liens, encumbrances, rights of first refusal or
         other adverse claims, as shall be equal to the result obtained by (1)
         multiplying the then current Purchase Price by the number of Preferred
         Share Fractions for which a Right is exercisable immediately prior to
         the first occurrence of a Section 13 Event (or, if a Section 11(a)(ii)
         Event has occurred prior to the first occurrence of a Section 13 Event,
         multiplying the number of such shares for which a Right was exercisable
         immediately prior to the first occurrence of a Section 11(a)(ii) Event
         by the Purchase Price in effect immediately prior to such first
         occurrence), and (2) dividing that product (which, following the first
         occurrence of a Section 13 Event, shall be referred to as the "Purchase
         Price" for each Right and for all purposes of this Agreement) by 50% of
         the current market price (determined pursuant to Section 11(d)(i)
         hereof) per Common Share of such Principal Party on the date of
         consummation of such Section 13 Event;

                                    (ii) such Principal Party shall thereafter
         be liable for, and shall assume, by virtue of such Section 13 Event,
         all the obligations and duties of the Company pursuant to this
         Agreement;

                                    (iii) the term "Company" shall thereafter be
         deemed to refer to such Principal Party, it being specifically intended
         that the provisions of Section 11 hereof shall apply only to such
         Principal Party following the first occurrence of a Section 13 Event;

                                    (iv) such Principal Party shall take such
         steps (including, but not limited to, the reservation of a sufficient
         number of its Common Shares) in connection with the consummation of any
         such transaction as may be necessary to assure that the provisions
         hereof shall thereafter be applicable, as nearly as reasonably may be,
         in relation to its Common Shares thereafter deliverable upon the
         exercise of the Rights; and

                                    (v) the provisions of Section 11(a)(ii)
         hereof shall be of no effect following the first occurrence of any
         Section 13 Event.

                           (b)  "Principal Party" shall mean

                                    (i) in the case of any transaction described
         in clause (x) or (y) of the first sentence of subsection (a), the
         Person that is the issuer of any securities into which Common Shares of
         the Company are converted in such merger or consolidation, and if no
         securities are so issued, the Person that is the other party to such
         merger or consolidation; and

                                    (ii) in the case of any transaction
         described in clause (z) of the first sentence of subsection (a), the
         Person that is the party receiving the greatest portion of the assets
         or earning power transferred pursuant to such transaction or
         transactions;

provided, however, that in the case of either (i) or (ii) above, (1) if the
Common Shares of such Person are not at such time and have not been continuously
over the preceding twelve (12) month period registered under Section 12 of the
Exchange Act, and such Person is a direct or indirect Subsidiary of another
Person the Common Shares of which are and have been so registered, "Principal
Party" shall refer to such other Person, and (2) in case such Person is a
Subsidiary, directly or indirectly, of more than one Person, the Common Shares
of two or more of which are and have been so registered, "Principal Party" shall
refer to whichever of such Persons is the issuer of the Common Shares having the
greatest aggregate market value.

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

                                    (i) prepare and file a registration
         statement under the Act, with respect to the Rights and the securities
         purchasable upon exercise of the Rights on an appropriate form, and
         will use its best efforts to cause such registration statement to (A)
         become effective as soon as practicable after such filing and (B)
         remain effective (with a prospectus at all times meeting the
         requirements of the Act) until the Expiration Date;

                                    (ii) use its best efforts to qualify or
         register the Rights and the securities purchasable upon exercise of the
         Rights under blue sky laws of such jurisdiction, as may be necessary or
         appropriate; and

                                    (iii) deliver to holders of the Rights
         historical financial statements for the Principal Party and each of its
         Affiliates that comply in all respects with the requirements for
         registration on Form 10 under the Exchange Act.

The provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers. In the event that a Section 13 Event
shall occur at any time after the



                                                   -28-




<PAGE>



occurrence of a Section 11(a)(ii) Event, the Rights that have not theretofore
been exercised shall thereafter become exercisable solely in the manner
described in Section 13(a).

                            (d) Notwithstanding anything in this Agreement to
the contrary, Section 13 (other than this subsection (d)) shall not be
applicable to, and the term "Section 13 Event" shall not include, a transaction
described in subparagraphs (x) and (y) of Section 13(a) if (i) such transaction
is consummated with a Person, or Persons who acquired Common Shares pursuant to
a Qualifying Offer (or 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 offer 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 or exchange offer. Upon consummation of any such transaction
contemplated by this subsection (d), all Rights hereunder shall expire.

                            (e) In the event that the Rights become exercisable
under subsection (a) (except as provided in subsection (d)), the Company, by
action of a majority of the Continuing Directors in office at the time, may
authorize that the Rights either (i) will only be or (ii) may, at the option of
the Principal Party be, exercisable for, 50% of the Common Shares of the
Principal Party that would otherwise be purchasable under subsection (a), in
consideration of the surrender to the Principal Party, as the successor to the
Company under subsection (a) (ii), of the Rights so exercised and without other
payment of the Purchase Price. Rights exercised under this subsection (e) shall
be deemed to have been exercised in full and shall be canceled.

                  Section 14.  Fractional Rights and Fractional Shares.

                            (a) The Company shall not be required to issue
fractions of Rights, except prior to the Distribution Date as provided in
Section 11(p) hereof, or to distribute Rights Certificates that 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 purposes of this
subsection (a), the current market value of a whole Right shall be the closing
price of the Rights for the Trading Day immediately prior to the date on which
such fractional Rights would have been otherwise issuable. The closing price of
the Rights for any day shall be the last sale price, regular way, or, in case no
such sale takes place on such day, the average of the closing bid and asked
prices, regular way, in either case as reported in the principal consolidated
transaction reporting system with respect to securities listed or admitted to
trading on the 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



                                      -29-




<PAGE>



reporting system with respect to securities listed on the principal national
securities exchange on which the Rights are listed or admitted to trading, or if
the Rights are not listed or admitted to trading on any national securities
exchange, the last quoted price or, if not so quoted, the average of the high
bid and low asked prices in the over-the-counter market, as reported by Nasdaq
or such other system then in use or, if on any such date the Rights are not
quoted by any such organization, the average of the closing bid and asked prices
as furnished by a professional market maker making a market in the Rights
selected by the Board of Directors of the Company. If on any such date no such
market maker is making a market in the Rights the fair value of the Rights on
such date as determined in good faith by the Board of Directors of the Company
shall be used.

                            (b) The Company shall not be required to issue
fractions of Preferred Shares upon exercise of the Rights or to distribute
certificates which evidence fractional Preferred Shares, except in each case for
fractions which are integral multiples of Preferred Shares. In lieu of
fractional Preferred Shares that are not integral multiples of Preferred Shares,
the Company may pay to the registered holders of Rights Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market value of a Preferred Share. For purposes of this
subsection (b), the current market value of one Preferred Share shall be the
closing price of a Preferred Share (as determined pursuant to Section 11(d)(ii)
hereof) for the Trading Day immediately prior to the date of such exercise.

                            (c) Following the occurrence of a Triggering Event,
the Company shall not be required to issue fractions of Common Shares upon
exercise of the Rights or to distribute certificates that evidence fractional
Common Shares. In lieu of fractional Common Shares, the Company may pay to the
registered holders of Rights Certificates at the time such Rights are exercised
as herein provided an amount in cash equal to the same fraction of the current
market value of one Common Share. For purposes of this subsection (c), the
current market value of one Common Share shall be the closing price of one
Common Share (as determined pursuant to Section 11(d)(i) hereof) for the Trading
Day immediately prior to the date of such exercise.

                            (d) Whenever a payment for fractional Rights or
fractional shares is to be made by the Rights Agent, the Company shall (i)
promptly prepare and deliver to the Rights Agent a certificate setting forth in
reasonable detail the facts related to such payment and the process and/or
formulas utilized in calculating such payments, and (ii) provide sufficient
monies to the Rights Agent in the form of fully collected funds to make such
payments. The Rights Agent shall be fully protected in relying on such
certificate and shall have no duty with respect to and shall not be deemed to
have knowledge of any payment for fractional Rights or fractional shares under
this Section 4 unless and until it shall have received such a certificate and
sufficient monies.

                            (e) The holder of a Right or a beneficial interest
in a Right by the acceptance thereof expressly waives his right to receive any
fractional Rights or any fractional Common Shares upon exercise of a Right,
except as permitted by this Section 14.

                  Section 15. Rights of Action. All rights of action in respect
of this Agreement 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
Rights Agent or 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 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 or beneficial interests
therein, it is specifically acknowledged that the holders of Rights or
beneficial interests therein would not have an adequate remedy at law for any
breach of this Agreement and shall be entitled to specific performance of the
obligations hereunder and injunctive relief against actual or threatened
violations of the obligations hereunder of any Person subject to this Agreement.

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

                            (a) prior to the Distribution Date, beneficial
interests in the Rights will be transferable only in connection with the
transfer of 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 office of the Rights Agent designated for such purposes, duly
endorsed or accompanied by a proper instrument of transfer and with the
appropriate forms and certificates fully executed;

                            (c) subject to Section 6(a) and Section 7(f) hereof,
the Company and the Rights Agent may deem and treat the Person in whose name a
Rights Certificate (or, prior to the Distribution Date, the associated Common
Share 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 Share 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 required to be affected by any
notice to the contrary; and




                                                   -31-




<PAGE>



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

                  Section 17. Rights Certificate Holder Not Deemed a
Shareholder. No holder, as such, of any Rights Certificate shall be entitled to
vote, receive dividends or be deemed for any purpose the holder of the number of
Preferred Share Fractions or any other securities of the Company (including the
Common Shares) that may at any time be issuable on the exercise of the Rights
represented thereby, nor shall anything contained herein or in any Rights
Certificate be construed to confer upon the holder of any Rights Certificate, as
such, any of the rights of a 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 24 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.

                  Section 18.  Concerning the Rights Agent.

                            (a) The Company agrees to pay to the Rights Agent
reasonable compensation for all services rendered by it hereunder and, from time
to time, on demand of the Rights Agent, its reasonable expenses and counsel fees
and disbursements and other disbursements incurred in the preparation,
execution, delivery, amendment, administration and execution of this Agreement
and the exercise and performance of its duties hereunder. The Company also
agrees to indemnify the Rights Agent and its directors, officers, employees and
agents, for and to hold each of them harmless against, any loss, liability,
damage, judgment, fine, penalty, claim, demand, settlement, cost or expense,
incurred without gross negligence, bad faith or willful misconduct on the part
of the Rights Agent or any such indemnified party, for any action taken,
suffered or omitted by the Rights Agent in connection with the acceptance or
administration of this Agreement or the exercise of its duties hereunder,
including without limitation the costs and expenses of defending against any
claim of liability in the premises.

<PAGE>



                            (b) The Rights Agent shall be protected and shall
incur no liability for or in respect of any action taken, suffered or omitted by
it in connection with the acceptance and administration of this Agreement or in
the exercise of its duties hereunder in reliance upon any Rights Certificate or
certificate for 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.

                  Section 19.  Merger or Consolidation or Change of Name of
Rights Agent.

                            (a) Any Person into which the Rights Agent or any
successor Rights Agent may be merged or with which it may be consolidated, or
any Person resulting from any merger or consolidation to which the Rights Agent
or any successor Rights Agent shall be a party, or any Person succeeding to the
shareholder services or stock transfer 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, however, that such Person would be
eligible for appointment as a successor Rights Agent under the provisions of
Section 21 hereof.

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

                  Section 20. Duties of Rights Agent. The Rights Agent
undertakes the duties and obligations, and only the duties and obligations,
expressly imposed by this Agreement (and no implied duties or obligations) upon
the following terms and conditions, by all of which the Company and the holders
of Rights Certificates or beneficial interests in the Rights, 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 advice or written opinion of
such counsel shall be full and complete authorization and protection to the
Rights Agent, and the Rights Agent shall incur no liability for or in respect
of, any action taken, suffered or omitted by it in good faith and in accordance
with such advice or opinion.



                                                   -33-




<PAGE>



                            (b) Whenever in the performance of its duties under
this Agreement the Rights Agent shall deem it necessary or desirable that any
fact or matter (including, without limitation, the identity of any Acquiring
Person and the determination of "current market price") be proved or established
by the Company prior to taking, suffering or omitting 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 the Chairman of the Board, the President, any Vice
President, the Treasurer, any Assistant Treasurer, the Secretary or any
Assistant Secretary of the Company and delivered to the Rights Agent; and such
certificate shall be full authorization and protection to the Rights Agent and
the Rights Agent shall incur no liability for or in respect of any action taken,
suffered or omitted in good faith by it under the provisions of this Agreement
in reliance upon such certificate.

                            (c) The Rights Agent shall be liable hereunder only
for its own gross negligence, bad faith or willful misconduct; provided, however
that the Rights Agent shall not be liable for special, indirect, incidental or
consequential loss or damage of any kind whatsoever, even if the Rights Agent
has been advised of the likelihood of such loss or damage.

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

                            (e) The Rights Agent shall not be under any
liability or responsibility in respect of the validity of any provision 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
adjustment required under the provisions of this Agreement or responsible for
the manner, method or amount of any such adjustment or the ascertaining of the
existence of facts that would require any such adjustment (except with respect
to the exercise of Rights evidenced by Rights Certificates after actual notice
of any such adjustment); nor shall it by any act hereunder be deemed to make any
representation or warranty as to the authorization or reservation of any Common
Shares to be issued pursuant to this Agreement or any Rights Certificate or as
to whether any Common Shares or Preferred Shares will, when so issued, be
validly authorized and issued, fully paid and nonassessable.

                            (f) The Company agrees that it will perform,
execute, acknowledge and deliver or cause to be performed, executed,
acknowledged and delivered all such further and



                                      -34-




<PAGE>



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 President, any Vice
President, the Secretary, any Assistant Secretary, the Treasurer or any
Assistant Treasurer of the Company, and to apply to such officers for advice or
instructions in connection with its duties, and such instructions shall be full
authorization and protection for the Rights Agent and the Rights Agent shall
incur no liability for or in respect of any action taken, suffered or omitted to
be taken by it in good faith in accordance with instructions of any such
officer. The Rights Agent may conclusively rely on the most recent instructions
provided to it by any such officer.

                            (h) The Rights Agent and any shareholder, affiliate,
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 the Rights Agent under this Agreement and none of such
actions shall constitute a breach of trust. Nothing herein shall preclude the
Rights Agent from acting in any other capacity for the Company or for any other
Person or 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 or any other Person
resulting from any such act, default, neglect or misconduct, absent gross
negligence, bad faith or willful misconduct in the selection and continued
employment thereof.

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

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

                  Section 21. Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon thirty (30) days' prior written notice mailed to the Company and
to each transfer agent of the Common Shares and 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
thirty (30) days' prior written notice mailed to the Rights Agent or successor
Rights Agent, as the case may be, and to each transfer agent of the Common
Shares and 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 otherwise become incapable of acting, the Company shall
appoint a successor to the Rights Agent. If the Company shall fail to make such
appointment within a period of thirty (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 any registered holder of any Rights
Certificate may apply to any court of competent jurisdiction for the appointment
of a new Rights Agent. Any successor Rights Agent, whether appointed by the
Company or by such a court, shall be (a) a Person organized, doing business and
in good standing under the laws of the United States or of any state, having a
principal office in the State of New York or the Commonwealth of Pennsylvania,
that is authorized by law to exercise shareholder services and stock transfer
powers and is subject to supervision or examination by federal or state
authority and that has at the time of its appointment as Rights Agent a combined
capital and surplus of at least $50,000,000 or (b) an Affiliate of any such
Person. After appointment, the successor Rights Agent shall be vested with the
same powers, rights, duties and responsibilities as if it had been originally
named as Rights Agent without further act or deed; but the predecessor Rights
Agent shall deliver and transfer to the successor Rights Agent any property at
the time held by it hereunder, and execute and deliver any further assurance,
conveyance, act or deed necessary for the purpose. Not later than the effective
date of any such appointment, the Company shall file notice thereof in writing
with the predecessor Rights Agent and each transfer agent of the Common Shares
and Preferred Shares and mail a notice thereof in writing to the registered
holders of the Rights Certificates or, prior to the Distribution Date, to the
registered holders of the Common Shares. In case at the time such successor
Rights Agent shall succeed to the agency and trust created by this Agreement,
any of the Rights Certificates shall have been countersigned but not delivered,
any such successor Rights Agent may adopt the countersignature of a predecessor
Rights Agent and deliver such Rights Certificates so countersigned; and in case
at that time any of the Rights Certificates shall not have been countersigned,
any successor Rights Agent may countersign such Rights Certificates either in
the name of the predecessor or in the name of the successor Rights Agent; and in
all such cases such Rights Certificates shall have the full force provided in
the Rights Certificates and in this Agreement. Failure to give any notice
provided for in this Section 21, however, or any defect therein, shall not
affect the legality or



                                      -36-




<PAGE>



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. In
addition, in connection with the issuance, sale or delivery of Common Shares
following the Distribution Date and prior to the redemption or expiration of the
Rights, the Company (a) shall, with respect to Common Shares so issued, sold or
delivered pursuant to the exercise of stock options, stock appreciation rights,
grants or awards outstanding on the Distribution Date under any benefit plan or
arrangement for employees or directors, or upon the exercise, conversion or
exchange of securities outstanding on the Record Date or hereinafter issued by
the Company, and (b) may, in any other case, if deemed necessary or appropriate
by the Board of Directors of the Company, issue Rights Certificates representing
the appropriate number of Rights in connection with such issuance or sale;
provided, however, that (i) no such Rights Certificate shall be issued if, and
to the extent that, the Company shall be advised by counsel that such issuance
would create a significant risk of material adverse tax consequences to the
Company or the Person to whom such Rights Certificate would be issued, and (ii)
no such Rights Certificate shall be issued if, and to the extent that,
appropriate adjustment shall otherwise have been made in lieu of the issuance
thereof.

                  Section 23.  Redemption and Termination.

                            (a) The Board of Directors of the Company may, at
its option, at any time prior to the earlier of (i) the Close of Business on the
tenth day following a Stock Acquisition Date (or, if the Stock Acquisition Date
shall have occurred prior to the Record Date, the Close of Business on the tenth
day following the Record Date), or (ii) the Close of Business on the Final
Expiration Date, redeem all but not less than all the then outstanding Rights at
a redemption price of $.01 per Right, as such amount may be appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof (such redemption price being hereinafter
referred to as the "Redemption Price") and the Company may, at its option, pay
the Redemption Price either in Common Shares (based on the "current market
price", as defined in Section 11(d)(i) hereof, of the Common Shares at the time
of redemption) or cash; provided, however, if the Board of Directors of the
Company authorizes redemption of the Rights in either of the circumstances set
forth in clauses (i) and (ii) of this proviso, then there must be Continuing
Directors then in office and such authorization shall require the concurrence of
a majority of such



                                      -37-




<PAGE>



Continuing Directors; and provided further, however, that if, following the
occurrence of a Stock Acquisition Date and following the expiration of the right
of redemption hereunder but prior to any Triggering Event, (i) an Acquiring
Person shall have transferred or otherwise disposed of a number 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 a Triggering Event or the Company (with the approval of the
majority of Continuing Directors) shall have issued additional equity
securities, in either instance such that such Person is thereafter a Beneficial
Owner of 10% or less of the outstanding Common Shares, and (ii) there is no
other Acquiring Person immediately following the occurrence of the event
described in clause (i), then the right of redemption shall be reinstated and
thereafter be subject to the provisions of this Section 23. Notwithstanding
anything contained in this Agreement to the contrary, the Rights shall not be
exercisable after the first occurrence of a Section 11(a)(ii) Event until such
time as the Company's right of redemption hereunder has expired.

                            (b) Immediately upon the action of the Board of
Directors of the Company ordering the redemption of the Rights, without any
notice, or further action, the right to exercise the Rights will terminate and
the only right thereafter of the holders of Rights shall be to receive the
Redemption Price for each Right so held. Promptly after the action of the Board
of Directors ordering the redemption of the Rights, the Company shall give
notice of such redemption to the Rights Agent and the holders of the then
outstanding Rights by, in the case of notice to holders, mailing such notice to
all such holders at each holder's last address as it appears upon the registry
books of the Rights Agent or, prior to the Distribution Date, on the registry
books of the Transfer Agent for the Common Shares. Any notice that 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 null and void pursuant to the provisions of
Section 7(e) 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 Company's Board of Directors shall not be empowered to effect such exchange
at any time after any Person (other than the Company, any Subsidiary of the
Company, any employee benefit plan of the Company or any such Subsidiary, or any
Person organized, appointed or established by the Company for or pursuant to



                                      -38-




<PAGE>



the terms of any such plan), together with all Affiliates and Associates of such
Person, becomes the Beneficial Owner of fifty percent (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 the holders 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 shall
promptly notify the Rights Agent of any 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 7(e) hereof) held by each holder of Rights.

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

                            (d) 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, there shall
be paid 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 subsection (d), the current market value of a
whole Common Share shall be the closing price of a Common Share (as determined
pursuant to the second sentence of Section 11(d) hereof) for the Trading Day
immediately prior to the date of exchange pursuant to this Section 24.

                  Section 25.  Notice of Certain Events.

                            (a) In case the Company shall propose, at any time
after the Distribution Date, (i) to pay any dividend payable in stock of any
class to the holders of Preferred



                                                   -39-




<PAGE>



Shares or to make any other distribution to the holders of Preferred Shares
(other than a regular quarterly dividend out of earnings or retained earnings of
the Company), or (ii) to offer to the holders of 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, or
(iii) to effect any reclassification of its Preferred Shares (other than a
reclassification involving only the subdivision of outstanding Preferred
Shares), or (iv) to effect any consolidation or merger into or with any other
Person (other than a Subsidiary of the Company in a transaction which complies
with Section 11(o) hereof), 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 transaction or a series of related transactions, of more than 50% of the
assets or earning power of the Company and its Subsidiaries (taken as a whole)
to any other Person or Persons (other than the Company and/or any of its
Subsidiaries in one or more transactions each of which complies with Section
11(o) hereof), or (v) to effect the liquidation, dissolution or winding up of
the Company, then, in each such case, the Company shall give to the Rights Agent
and to each holder of a Rights Certificate, to the extent feasible and 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, 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 Preferred Shares, if any
such date is to be fixed, and such notice shall be so given in the case of any
action covered by clause (i) or (ii) above at least twenty (20) days prior to
the record date for determining holders of Preferred Shares for purposes of such
action, and in the case of any such other action, at least twenty (20) days
prior to the date of the taking of such proposed action or the date of
participation therein by the holders of Preferred Shares, whichever shall be the
earlier.

                            (b) Upon the occurrence of a Section 11(a)(ii)
Event, (i) the Company shall as soon as practicable thereafter give to each
holder of a Rights Certificate, to the extent feasible and in accordance with
Section 26 hereof, a notice of the occurrence of such event, which shall specify
the event and the consequences of the event to holders of Rights under Section
11(a)(ii) hereof, and (ii) all references in the preceding paragraph to
Preferred Shares shall be deemed thereafter to refer to Common Shares and/or, if
appropriate, other securities.

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

                           Attention: General Counsel

prepaid, addressed to such holder at the address of such holder as shown on the
registry books of the Company.

                  Section 27. Supplements and Amendments. Prior to the
Distribution Date and subject to the penultimate sentence of this Section 27,
the Company may and the Rights Agent shall, if the Company so directs,
supplement or amend any provision of this Agreement without the approval of any
holders of certificates representing Common Shares. From and after the

<PAGE>



Redemption Price, the Final Expiration Date, the Purchase Price or the number of
Preferred Share Fractions for which a Right is exercisable, (ii) any supplement
or amendment shall be effective only if there are Continuing Directors and shall
require the concurrence of a majority of such Continuing Directors if: (x) such
supplement or amendment occurs on or after the time a Person becomes an
Acquiring Person, or (y) such supplement or amendment occurs on or after the
date of a change (resulting from a proxy or consent solicitation) in a majority
of the directors in office at the commencement of such solicitation if any
Person who is a participant in such solicitation has stated (or, if upon the
commencement of such solicitation, a majority of the Board of Directors of the
Company has determined in good faith) that such Person (or any of its Affiliates
or Associates) intends to take, or may consider taking, any action that would
result in such Person becoming an Acquiring Person or that would cause the
occurrence of a Triggering Event unless, concurrent with such solicitation, such
Person (or one or more of its Affiliates or Associates) is making a cash tender
offer pursuant to a Schedule 14D-1 (or any successor form) filed with the
Securities and Exchange Commission for all outstanding Common Shares not
beneficially owned by such Person (or by its Affiliates or Associates), and
(iii) no supplement or amendment that changes or increases the obligations and
duties of the Rights Agent under this Agreement shall be effective without the
consent of the Rights Agent. Prior to the Distribution Date, the interests of
the beneficial owners of Rights shall be deemed coincident with the interests of
the holders of Common Shares.

                  Section 28. Successors. All the covenants and provisions of
this Agreement by or for the benefit of the Company or the Rights Agent shall
bind and inure to the benefit of their respective successors and assigns
hereunder.

                  Section 29. Determinations and Actions by the Board of
Directors, etc. For all purposes of this Agreement, any calculation of the
number of Common Shares outstanding at any particular time, including for
purposes of determining the particular percentage of such outstanding Common
Shares of which any Person is the Beneficial Owner, shall be made in accordance
with the last sentence of Rule 13d-3(d)(1)(i) of the General Rules and
Regulations under the Exchange Act. The Board of Directors of the Company (with,
where specifically provided for herein, the concurrence of the Continuing
Directors) shall have the exclusive power and authority to administer this
Agreement and to exercise all rights and powers specifically granted to the
Board (with, where specifically provided for herein, the concurrence of the
Continuing Directors) or to the Company, or as may be necessary or advisable in
the administration of this Agreement, including, without limitation, the right
and power to (i) interpret the provisions of this Agreement, and (ii) make all
determinations deemed necessary or advisable for the administration of this
Agreement (including a determination to redeem or not redeem the Rights or to
amend or supplement the Agreement). All such actions, calculations,
interpretations and determinations (including, for purposes of clause (y) below,
all omissions



                                                   -42-




<PAGE>



with respect to the foregoing) that are done or made by the Board (with, where
specifically provided for herein, the concurrence of the Continuing Directors)
in good faith, shall (x) be final, conclusive and binding on the Company, the
Rights Agent, the holders of the Rights and all other Persons, and (y) not
subject the Board or the Continuing Directors to any liability to the holders of
the Rights. For purposes of this Agreement, the Rights Agent shall be allowed to
assume that all such actions, calculations, interpretations and determinations
have been done or made by the Board in good faith.

                  Section 30. Benefits of this Agreement. Nothing in this
Agreement shall be construed to give to any Person other than the Company, the
Rights Agent and the registered holders of the Rights Certificates (and, prior
to the Distribution Date, registered holders of the Common Shares) any legal or
equitable right, remedy or claim under this Agreement; but this Agreement shall
be for the sole and exclusive benefit of the Company, the Rights Agent and the
registered holders of the Rights Certificates (and, prior to the Distribution
Date, registered holders of the Common Shares).

                  Section 31. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable for any purpose or under
any set of circumstances or as applied to any Person, such invalid, void or
unenforceable term, provision, covenant or restriction shall continue in effect
to the maximum extent possible for all other purposes, under all other
circumstances and as applied to all other Persons; and the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated;
provided, however, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board of
Directors of the Company determines in its good faith judgment that severing the
invalid language from this Agreement would adversely affect the purpose or
effect of this Agreement, the right of redemption set forth in Section 23 hereof
shall be reinstated and shall not expire until the Close of Business on the
tenth day following the date of such determination by the Board of Directors.
Without limiting the foregoing, if any provisions requiring that a determination
be made by less than the entire Board (or at a time or with the concurrence of a
group of directors consisting of less than the entire Board) is held by a court
of competent jurisdiction or other authority to be invalid, void or
unenforceable, such determination shall then be made by the Board in accordance
with applicable law and the Company's Certificate of Incorporation and by-laws.

                  Section 32. Governing Law. This Agreement, each Right and each
Rights Certificate issued hereunder shall be deemed to be a contract made under
the laws of the Commonwealth of Pennsylvania and for all purposes shall be
governed by and construed in



                                      -43-

accordance with the laws of such jurisdiction applicable to contracts made and
to be performed entirely within such jurisdiction; except that all provisions
regarding the rights, duties and obligations of the Rights Agent shall by
governed by and construed in accordance with the laws of the State of New York
applicable to contracts made and to be performed entirely within such
jurisdiction.

                  Section 33. Counterparts. This Agreement may be executed in
any number of counterparts and each of such counterparts shall for all purposes
be deemed to be an original, and all such counterparts shall together constitute
but one and the same instrument.
       

                  Section 34. Descriptive Headings. Descriptive headings of the
several Sections of this Agreement are inserted for convenience only and shall
not control or affect the meaning or construction of any of the provisions
hereof.

                     RESOLUTION OF THE BOARD OF DIRECTORS OF
                        PHILADELPHIA SUBURBAN CORPORATION
                          ESTABLISHING AND DESIGNATING
                 SERIES A JUNIOR PARTICIPATING PREFERRED SHARES
                       AS A SERIES OF THE PREFERRED STOCK


RESOLVED, that pursuant to the authority expressly vested in the Board of
Directors of Philadelphia Suburban Corporation (the "Corporation") by Article
FIFTH of the Articles of Incorporation of the Corporation, the Board of
Directors hereby fixes and determines the voting rights, designations,
preferences, qualifications, privileges, limitations, restrictions, options,
conversion rights and other special or relative rights of the first series of
the Series Preferred Stock, par value $1.00 per share, which shall consist of
100,000 shares and shall be designated as Series A Junior Participating
Preferred Shares (the "Series A Preferred Shares").

Special Terms of the Series A Preferred Shares

                  Section 1.  Dividends and Distributions.

                  (a) The rate of dividends payable per share of Series A
Preferred Shares on the first day of January, April, July and October in each
year or such other quarterly payment date as shall be specified by the Board of
Directors (each such date being referred to herein as a "Quarterly Dividend
Payment Date"), commencing on the first Quarterly Dividend Payment Date after
the first issuance of a share or fraction of a share of the Series A Preferred
Shares, shall be (rounded to the nearest cent) equal to the greater of (i)
$10.00 or (ii) subject to the provision for adjustment hereinafter set forth,
1,000 times the aggregate per share amount of all cash dividends, and 1,000
times the aggregate per share amount (payable in cash, based upon the fair
market value at the time the non-cash dividend or other distribution is declared
or paid as determined in good faith by the Board of Directors) of all non-cash
dividends or other distributions other than a dividend payable in shares of
Common Stock or a subdivision of the outstanding shares of Common Stock (by
reclassification or otherwise), declared on the Common Stock, $.50 par value per
share, of the Corporation since the immediately preceding Quarterly Dividend
Payment Date, or, with respect to the first Quarterly Dividend Payment Date,
since the first issuance of any share or fraction of a share of the Series A
Preferred Shares. Dividends on the Series A Preferred Shares shall be paid out
of funds legally available for such purpose. In the event the Corporation shall
at any time after March 1, 1998 (the "Rights Declaration Date") (i) declare any
dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding shares of Common Stock, or (iii) combine the outstanding shares of
Common Stock into a smaller number of shares, then in each such case the amounts
to which holders of Series A Preferred Shares were entitled immediately prior to
such event under clause (ii) of the preceding sentence shall be adjusted by
multiplying each such amount by a fraction the numerator of which


                                       A-1

<PAGE>



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) Dividends shall begin to accrue and be cumulative on
outstanding Series A Preferred Shares from the Quarterly Dividend Payment Date
next preceding the date of issue of such Series A Preferred Shares, unless the
date of issue of such shares is prior to the record date for the first Quarterly
Dividend Payment Date, in which case dividends on such shares shall begin to
accrue from the date of issue of such shares, or unless the date of issue is a
Quarterly Dividend Payment Date or is a date after the record date for the
determination of holders of Series A Preferred Shares entitled to receive a
quarterly dividend and before such Quarterly Dividend Payment Date, in either of
which events such dividends shall begin to accrue and be cumulative from such
quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear
interest. Dividends paid on the Series A Preferred Shares in an amount less than
the total amount of such dividends at the time accrued and payable on such
shares shall be allocated pro rata on a share-by-share basis among all such
shares at the time outstanding.

                  Section 2. Voting Rights. In addition to any other voting
rights required by law, the holders of Series A Preferred Shares shall have the
following voting rights:

                  (a) Subject to the provision for adjustment hereinafter set
forth, each Series A Preferred Share shall entitle the holder thereof to 1,000
votes on all matters submitted to a vote of the shareholders of the Corporation.
In the event the Corporation shall at any time after the Rights Declaration Date
(i) declare any dividend on Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding shares of Common Stock, or (iii) combine the
outstanding shares of Common Stock into a smaller number of shares, then in each
such case the number of votes per share to which holders of Series A Preferred
Shares were entitled immediately prior to such event shall be adjusted by
multiplying such number by a fraction the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

                  (b) In the event that dividends upon the Series A Preferred
Shares shall be in arrears to an amount equal to six full quarterly dividends
thereon, the holders of such Series A Preferred Shares shall become entitled to
the extent hereinafter provided to vote noncumulatively at all elections of
directors of the Corporation, and to receive notice of all shareholders'
meetings to be held for such purpose. At such meetings, to the extent that
directors are being elected, the holders of such Series A Preferred Shares
voting as a class shall be entitled solely to elect two members of the Board of
Directors of the Corporation; and all other directors of the Corporation shall
be elected by the other shareholders of the Corporation entitled to vote in the
election of directors. Such voting rights of the holders of such Series A
Preferred Shares shall continue until all accumulated and unpaid dividends
thereon shall have been paid or funds sufficient therefor set aside, whereupon
all such voting rights of the holders of shares of such series shall cease,


                                       A-2

<PAGE>



subject to being again revived from time to time upon the reoccurrence of the
conditions above described as giving rise thereto.

                  At any time when such right to elect directors separately as a
class shall have so vested, the Corporation may, and upon the written request of
the holders of record of not less than 20% of the then outstanding total number
of shares of all the Series A Preferred Shares having the right to elect
directors in such circumstances shall, call a special meeting of holders of such
Series A Preferred Shares for the election of directors. In the case of such a
written request, such special meeting shall be held within 90 days after the
delivery of such request, and, in either case, at the place and upon the notice
provided by law and in the By-laws of the Corporation; provided, that the
Corporation shall not be required to call such a special meeting if such request
is received less than 120 days before the date fixed for the next ensuing annual
or special meeting of shareholders of the Corporation. Upon the mailing of the
notice of such special meeting to the holders of such Series A Preferred Shares,
or, if no such meeting be held, then upon the mailing of the notice of the next
annual or special meeting of shareholders for the election of directors, the
number of directors of the Corporation shall, ipso facto, be increased to the
extent, but only to the extent, necessary to provide sufficient vacancies to
enable the holders of such Series A Preferred Shares to elect the two directors
hereinabove provided for, and all such vacancies shall be filled only by vote of
the holders of such Series A Preferred Shares as hereinabove provided. Whenever
the number of directors of the Corporation shall have been increased, the number
as so increased may thereafter be further increased or decreased in such manner
as may be permitted by the By-laws and without the vote of the holders of Series
A Preferred Shares, provided that no such action shall impair the right of the
holders of Series A Preferred Shares to elect and to be represented by two
directors as herein provided.

                  So long as the holders of Series A Preferred Shares are
entitled hereunder to voting rights, any vacancy in the Board of Directors
caused by the death or resignation of any director elected by the holders of
Series A Preferred Shares, shall, until the next meeting of shareholders for the
election of directors, in each case be filled by the remaining director elected
by the holders of Series A Preferred Shares having the right to elect directors
in such circumstances.

                  Upon termination of the voting rights of the holders of any
series of Series A Preferred Shares the terms of office of all persons who shall
have been elected directors of the Corporation by vote of the holders of Series
A Preferred Shares or by a director elected by such holders shall forthwith
terminate.

                  (c) Except as otherwise provided herein, in the Articles of
Incorporation of the Corporation or by law, the holders of Series A Preferred
Shares and the holders of Common Stock (and the holders of shares of any other
series or class entitled to vote thereon) shall vote together as one class on
all matters submitted to a vote of shareholders of the Corporation.

                  Section 3. Reacquired Shares. Any Series A Preferred Shares
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 Series
Preferred Stock and may be reissued as part of a new series of Series Preferred
Stock to be created by resolution or resolutions of the Board of Directors.

                  Section 4. Liquidation, Dissolution or Winding Up. In the
event of any voluntary or involuntary liquidation, dissolution or winding up of
the Corporation, the holders of Series A Preferred Shares shall be entitled to
receive the greater of (a) $100.00 per share, plus accrued dividends to the date
of distribution, whether or not earned or declared, or (b) an amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 1,000
times the aggregate amount to be distributed per share to holders of Common
Stock. In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding shares of Common Stock, or (iii)
combine the outstanding shares of Common Stock into a smaller number of shares,
then in each such case the amount to which holders of Series A Preferred Shares
were entitled immediately prior to such event pursuant to clause (b) of the
preceding sentence shall be adjusted by multiplying such amount by a fraction
the numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

                  Section 5. 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 the Series
A Preferred Shares shall at the same time be similarly exchanged or changed in
an amount per share (subject to the provision for adjustment hereinafter set
forth) equal to 1,000 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 after the Rights Declaration Date (i) declare any
dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding shares of Common Stock, or (iii) combine the outstanding shares of
Common Stock into a smaller number of shares, then in each such case the amount
set forth in the preceding sentence with respect to the exchange or change of
shares of Series A Preferred Shares shall be adjusted by multiplying such amount
by a fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

                  Section 6. No Redemption. The Series A Preferred Shares shall
not be redeemable.

                  Section 7. Ranking. The Series A Preferred Shares shall rank
junior to all other series of the Corporation's Series Preferred Stock as to the
payment of dividends and the distribution of assets, unless the terms of any
such series shall provide otherwise.

                  Section 8. Fractional Shares. Series A Preferred Shares 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 Series A Preferred Shares.

                               RIGHTS CERTIFICATE


                  This certifies that ___________________, or registered
assigns, is the registered owner of the number of Rights set forth above, each
of which entitles the owner thereof, subject to the terms, provisions and
conditions of the Rights Agreement, dated as of March 1, 1998 (the "Rights

corporation (the "Company"), and ChaseMellon Shareholder Services, L.L.C., a New
Jersey limited liability company (the "Rights Agent"), to purchase from the
Company at any time prior to 5:00 P.M. (Philadelphia time) on March 1, 2008 at
the office or offices of the Rights Agent designated for such purpose, or its
successors as Rights Agent, one one-thousandth of a fully paid, nonassessable
share of Series A Junior Participating Preferred Stock (the "Preferred Share")
of the Company, at a purchase price (the "Purchase Price") of $90 per one
one-thousandth of a Preferred Share (such fraction, a "Preferred Share
Fraction"), upon presentation and surrender of this Rights Certificate with the
Form of Election to Purchase and related Certificate duly executed. Except as
provided in Sections 11(q) and 13(e) of the Rights Agreement, the Purchase Price
shall be paid, at the option of the Company, in cash or Common Stock, of the
Company (the "Common Shares") having an equivalent value. The number of Rights
evidenced by this Rights Certificate (and the number of Preferred Share
Fractions that may be purchased upon exercise thereof) set forth above, and the
Purchase Price per Preferred Share Fraction set forth above, are the number and
Purchase Price as of March 1, 1998, based on the Preferred Shares as constituted
at such date.

                  Except as otherwise provided in the Rights Agreement, upon the
occurrence of any Section 11(a)(ii) Event (as such term is defined in the Rights
Agreement), if the Rights evidenced by this Rights Certificate are beneficially
owned by (i) an Acquiring Person or Associate or Affiliate or Associate of any
Acquiring Person (as such terms are defined in the Rights Agreement), (ii) a
transferee of any Acquiring Person (of any such Associate or Affiliate) who
becomes a transferee after the Acquiring Person becomes such, or (iii) under
certain circumstances specified in the Rights Agreement, a transferee of a
person who, after such transfer, became an Acquiring Person, or an Affiliate or
Associate of an Acquiring Person, such Rights shall become null and void and no
holder hereof shall have any right with respect to such Rights from and after
the occurrence of any such Section 11(a)(ii) Event.

                  As provided in the Rights Agreement, the Purchase Price and
the number and kind of Preferred Shares or other securities that may be
purchased upon the exercise of the Rights evidenced by this Rights Certificate
are subject to modification and adjustment upon the happening of certain events,
including Triggering Events and a Section 11 (a) (ii) Event.

                  This Rights Certificate is subject to all of the terms,
covenants and restrictions of the Rights Agreement, which terms, covenants and
restrictions are hereby incorporated herein by

reference and made a part hereof and to which Rights Agreement reference is
hereby made for a full description of the rights, limitations of rights,
obligations, duties and immunities hereunder of the Rights Agent, the Company
and the holders of the Rights Certificates, which limitations of rights include
the temporary suspension of the exercisability of such Rights under the specific
circumstances set forth in the Rights Agreement. Copies of the Rights Agreement
are on file at the above-mentioned office of the Rights Agent and are also
available upon written request to the Company.

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

                  Subject to the provisions of the Rights Agreement, the Rights
evidenced by this Certificate may be redeemed by the Company at its option at a
redemption price of $.01 per Right at any time prior to the earlier of the Close
of Business (as such term is defined in the Rights Agreement) on (i) the tenth
day following the Stock Acquisition Date (as such time period may be extended
pursuant to the Rights Agreement), and (ii) the Final Expiration Date. Under
certain circumstances set forth in the Rights Agreement, the decision to redeem
shall require the concurrence of a majority of the Continuing Directors.

                  No fractional Preferred Shares will be issued upon the
exercise of any Right or Rights evidenced hereby (other than fractions which are
integral multiples of a Preferred Share, which may, as the election of the
Company, be evidenced by depositary receipts), but in lieu thereof a cash
payment will be made, as provided in the Rights Agreement.

                  No holder of this Rights Certificate shall be entitled to vote
or receive dividends or be deemed for any purpose the holder of Preferred Shares
or of any other securities of the Company (including Common Shares) that may at
any time be issuable on the exercise hereof, nor shall anything contained in the
Rights Agreement or herein be construed to confer upon the holder hereof, as
such, any of the rights of a 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 the Rights Agreement), or to receive dividends or subscription
rights, or otherwise, until the Right or Rights evidenced by this Rights
Certificate shall have been exercised as provided in the Rights Agreement.

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