Item 5. OTHER EVENTS.

Amendment to Shareholder Rights Plan.

     On September 17, 1997, the Board of Directors of Neose Technologies, Inc.
(the "Company") declared a dividend distribution of one right (a "Right") for
each outstanding share of Common Stock, $.01 par value ("Common Share"), of the
Company to stockholders of record at the close of business on October 6, 1997.
Each Right entitles the registered holder to purchase from the Company a unit
consisting of one one-hundredth of a share (a "Unit") of the Series A Junior
Participating Preferred Stock, $.01 par value ("Preferred Share"), of the
Company, or a combination of securities and assets of equivalent value, at a
purchase price of $150.00 per Unit (the "Purchase Price"), subject to
adjustment. On December 3, 1998, the Board of Directors of the Company (the
"Board"), in accordance with the terms of the Rights Agreement dated as of
September 26, 1997 between the Company and American Stock Transfer & Trust
Company, as Rights Agent, approved the amendment and restatement of the Rights
Agreement effective as of December 3, 1998 (the "Rights Agreement"). The
description and terms of the Rights, as amended, are set forth in the Rights
Agreement.

     Initially, ownership of the Rights will be evidenced by the Common Share
certificates representing shares then outstanding, and no separate certificates
evidencing the Rights ("Rights Certificates") will be distributed. The Rights
will separate from the Common Shares and a Distribution Date will occur upon the
earlier of (i) 10 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 15% or more of the
outstanding Common Shares (the "Stock Acquisition Date"), or (ii) the close of
business on such date as may be fixed by the Board, which date shall not be more
than 65 days following the commencement of a tender offer or exchange offer that
would result in a person or group beneficially owning 15% or more of the
outstanding Common Shares. Until the Distribution Date, (i) the Rights will be
evidenced by the Common Share certificates and will be transferred with and only
with such Common Share certificates, (ii) new Common Share certificates issued
after October 6, 1997 will contain a notation incorporating the Rights Agreement
by reference and (iii) 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 certificates.

     The Rights are not exercisable until the Distribution Date and will expire
at the close of business on October 6, 2007, 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, 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 October 6, 1997 and
prior to the Distribution Date will be issued with Rights.

     Except in the circumstances described below, after the Distribution Date
each Right will be exercisable for one one-hundredth 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 that are less than an integral multiple of one Preferred Share
(i.e., 100 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 becomes the beneficial owner
of more than 15% of the then outstanding Common Shares other than pursuant to a
tender offer that provides fair value to all stockholders, (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


                                       2

<PAGE>


Acquiring Person's ownership interest being increased by more than 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 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 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 $150.00 per Right, each Right not
otherwise voided following an event set forth in the preceding paragraph would
entitle its holder to purchase $300.00 worth of Common Shares (or other
consideration, as noted above) for $150.00. Assuming that the Common Shares had
a per share value of $50.00 at such time, the holder of each valid Right would
be entitled to purchase six Common Shares for $150.00. Alternatively, the
Company could permit the holder to surrender each Right in exchange for stock or
cash equivalent to three Common Shares (with a value of $150.00) 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 is
described in, or that follows a tender offer or exchange offer described in, the
second preceding paragraph), 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 two times the exercise price of the Right. Again, provision is made to
permit 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 dividends out of retained earnings of the Company as specified
in Section 1(a) of the Certificate of Designations establishing and designating
the Preferred Shares) or of subscription rights or warrants (other than those
referred to above).

     With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments amount to at least 1% of the Purchase
Price. 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 so long as
the Rights are still redeemable. Immediately upon the action of the Board
ordering redemption of the Rights, the Rights will terminate and the only right
of the holders of Rights will be to receive the $.01 redemption price.

     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. Although 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 the principal economic terms of the
Rights, any of the provisions of the Rights Agreement may be amended by the
Board prior to the Distribution Date. After the Distribution Date, the


                                       3

<PAGE>


provisions of the Rights Agreement may be amended by the Board 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.

     The foregoing summary description of the Rights does not purport to be
complete and is qualified in its entirety by reference to the Rights Agreement.

                      AMENDED AND RESTATED RIGHTS AGREEMENT

     AMENDED AND RESTATED RIGHTS AGREEMENT, dated as of December 3, 1998 (the
"Agreement"), between NEOSE TECHNOLOGIES, a Delaware corporation (the
"Company"), and AMERICAN STOCK TRANSFER & TRUST COMPANY, a New York banking
corporation (the "Rights Agent"), amending and restating in its entirety the
RIGHTS AGREEMENT, dated as of September 26, 1997, between the Company and the
Rights Agent.

                               W I T N E S S E T H

     WHEREAS, on September 17, 1997 (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 October 6, 1997 (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(p) 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-hundredth 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 stockholders 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 stockholders, (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 stockholders 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
stockholder, and (v) preserve the Board of Directors' bargaining power and
flexibility to deal with third-party acquirors and to otherwise seek to maximize
values for all stockholders; and


<PAGE>


     WHEREAS, pursuant to Section 26 of the Agreement, the Company and the
Rights Agent may from time to time supplement or amend any provision of the
Agreement in accordance with the terms of such Section 26; and

     WHEREAS, on December 3, 1998, the Board of Directors of the Company
authorized and approved the amendment and restatement of this Agreement as set
forth herein, all acts and things necessary to amend and restate the Agreement
have been done and performed, and the execution and delivery of the Agreement by
the Company and the Rights Agent have been in all respects duly authorized by
the Company and the Rights Agent.

     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:

     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 15% 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.

          (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").

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

          (i) that such Person or any of such Person's Affiliates or Associates,
     directly or indirectly, has the right to acquire (whether such right is
     exercisable immediately or only after the passage of time) pursuant to any
     agreement, arrangement or understanding (whether or not in writing) or upon
     the exercise of conversion rights, exchange rights, rights, warrants or
     options, or otherwise; provided, however, that a Person shall not be deemed
     the "Beneficial Owner" of, or to "beneficially own", (A) securities
     tendered pursuant to a tender or exchange offer made by such Person or any
     of such Person's Affiliates or Associates until such tendered securities
     are accepted for payment, purchase or exchange, or (B) securities issuable
     upon exercise


                                       2

<PAGE>


     of Rights at any time prior to the occurrence of a Triggering Event, or (C)
     securities issuable upon exercise of Rights from and after the occurrence
     of a Triggering Event which Rights were acquired by such Person or any of
     such Person's Affiliates or Associates prior to the Distribution Date or
     pursuant to Section 3(a) or Section 22 hereof (the "Original Rights") or
     pursuant to Section 11(i) hereof in connection with an adjustment made with
     respect to any Original Rights;

          (ii) that such Person or any of such Person's Affiliates or
     Associates, directly or indirectly, has the right to vote or dispose of or

     General Rules and Regulations under the Exchange Act), including without
     limitation pursuant to any agreement, arrangement or understanding, whether
     or not in writing; provided, 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: (A) arises solely from a revocable proxy given in response
     to a public proxy or consent solicitation made pursuant to, and in
     accordance with, the applicable provisions of the General Rules and
     Regulations under the Exchange Act, and (B) is not also then reportable by
     such Person on Schedule 13D under the Exchange Act (or any comparable or
     successor report); or

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

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.

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


                                       3

<PAGE>


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

          (f) "Common Share" shall mean the shares of Common Stock, par value
$.01 per share, of the Company and, to the extent that there are not a
sufficient number of Common Shares authorized to permit the full exercise of the
Rights, shares of any other class or series of the Company designated for such
purpose containing terms substantially similar to the terms of the Common
Shares, except that "Common Share" when used with reference to any Person other
than the Company shall mean the shares of capital stock of such Person with the
greatest voting power, or the equity securities or other equity interest having
power to control or direct the management, of such Person.

          (g) [Intentionally deleted.]

          (h) "Distribution Date" shall have the meaning set forth in Section 3

     Section 2. Appointment of Rights Agent.

          (a) The Company hereby appoints the Rights Agent to act as agent for
the Company and trustee for the beneficial owners of the Rights (who, in
accordance with Section 3 hereof, shall prior to the Distribution Date also be
the holders of the Common Shares) in accordance with the terms and conditions
hereof, and the Rights Agent hereby accepts such appointment. The Company may

          (b) On the Record Date, the Company will deliver a Rights Certificate
to the Rights Agent, registered in the name of the Rights Agent as trustee for
the beneficial owners of the Rights represented thereby, for that number of

Date, and the Rights Agent shall hold the Rights represented thereby in trust
for the beneficial owners in accordance with the provisions of this Agreement.

          (a) Until the earlier of (i) the close of business on the tenth day

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,


                                       5

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 15% 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). As soon as practicable after the Distribution Date,
the Rights Agent will send by first-class, insured, postage prepaid mail, to
each record holder of 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. Upon the distribution of the
Rights Certificates as provided in this subsection (a), the trust created hereby
shall cease.

          (b) As promptly as practicable following the Record Date, the Company
will send a copy of a Summary of Rights, in substantially the form of Exhibit C
hereto (the "Summary of Rights"), by first-class, postage prepaid mail, to each
record holder of the Common Shares as of the close of business on the Record
Date, at the address of such holder shown on the records of the Company. With
respect to certificates for the Common Shares outstanding as of the Record Date,
until the Distribution Date, beneficial interests in the Rights will be
evidenced by such certificates for the Common Shares and 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


                                       6

<PAGE>


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 Amended and
     Restated Rights Agreement between Neose Technologies, Inc. (the "Company")
     and American Stock Transfer & Trust Company (the "Rights Agent") dated as
     of December 3, 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 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 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


                                       7

<PAGE>


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 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 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


                                       8

<PAGE>


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, the Rights Agent will keep or
cause to be kept, at its principal office or offices designated as the
appropriate place for surrender of Rights Certificates upon exercise or
transfer, books for registration and transfer of the Rights Certificates issued
hereunder. Such books shall show the 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 principal office or offices of the Rights Agent designated for such
purpose. Neither the Rights Agent nor the Company shall be obligated to take any
action whatsoever with respect to the transfer of any such surrendered Rights
Certificate until the registered holder shall have completed and 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 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 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 reasonably


                                       9

<PAGE>


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 of Rights.

          (a) Subject to subsection (e), the registered holder of any Rights
Certificate may exercise the Rights evidenced thereby (except as otherwise
provided herein including, without limitation, the restrictions on
exercisability set forth in Section 9(c), Section 11(a)(iii) and Section 23(a)
hereof) in whole or in part at any time after the Distribution Date upon
surrender of the Rights Certificate, with the form of election to purchase and
the certificate on the reverse side thereof duly executed, to the Rights Agent
at the principal office or offices of the Rights Agent designated for such
purpose, together with payment of the aggregate Purchase Price (except as
provided in Section 11(q) hereof) with respect to the total number of Preferred
Share Fractions (or Common Shares, other securities, cash or other assets, as
the case may be) as to which such surrendered Rights are then exercisable
(except as provided in Section 11(q) hereof), at or prior to the earliest of (i)
the close of business on October 6, 2007 (the "Final Expiration Date"), (ii) the
consummation of a transaction contemplated by Section 13(d) hereof, or (iii) the
time at which the Rights are redeemed or terminated as provided in Section 23
hereof (the earlier of (i), (ii) and (iii) being herein referred to as the
"Expiration Date").

          (b) The Purchase Price for each Preferred Share Fraction pursuant to
the exercise of a Right shall initially be $150.00, and shall be subject to
adjustment from time to time as provided in Sections 11 and 13(a) hereof and
shall be payable in accordance with subsection (c).

          (c) Upon receipt of a Rights Certificate representing exercisable
Rights, with the form of election to purchase and the certificate duly executed,
accompanied by payment, with respect to each Right so exercised, of the Purchase
Price 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 transfer tax, 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 such 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


                                       10

<PAGE>


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 the same to be delivered to or
upon the order of the registered holder of such Rights Certificate, registered
in such name or names as may be designated by such holder, and (iv) after
receipt thereof, deliver such cash, if any, to or upon the order of the
registered holder of such Rights Certificate. 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 appropriate.

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

          (e) Notwithstanding anything in this Agreement to the contrary, from
and after the first occurrence of 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)


                                       11

<PAGE>


Event. The Company shall use all reasonable efforts to insure that the
provisions of this Section 7(e) and Section 4(b) hereof are complied with, but
shall have no liability to any holder of Rights Certificates or other Person as
a result of its failure to make any determinations with respect to an Acquiring
Person or its Affiliates, Associates or transferees hereunder.

          (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) completed and signed the certificate contained in the form of election to
purchase set forth on the reverse side of the Rights Certificate surrendered for
such exercise, and (ii) provided such additional evidence of the identity of the
Beneficial Owner (or former Beneficial Owner) or Affiliates or Associates
thereof as the Company shall reasonably request.

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

     Section 9. Reservation and Availability of Capital Stock; 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 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 national securities
exchange, the Company shall use its best efforts to cause, from and after such
time as the Rights become exercisable,


                                       12

<PAGE>


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 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 date of the expiration of the
Rights. 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. 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.

          (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 federal and state transfer taxes and 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


                                       13

<PAGE>


Share Fractions (or Common Shares or other securities, as 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 transfer taxes) 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 stockholder 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 number and kind
     of Preferred Shares or capital stock, as the case may be, that, if such
     Right had


                                       14

<PAGE>


     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 acquire or 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 Company's (or its
          Subsidiaries') past practices, or (6) shall receive the benefit,
          directly or indirectly (except proportionately as a stockholder and
          except if resulting from a requirement of law or governmental
          regulation),


                                       15

<PAGE>


          of any loans, advances, guarantees, pledges or other financial
          assistance or any tax credits or other tax advantage 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 15% or more of the Common Shares then outstanding,
          unless the event causing the 15% 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 that provide fair value to all stockholders, as
          determined by at least a majority of the members of the Board of
          Directors of the Company, 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
          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 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


                                       16

<PAGE>


     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 (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 Second Amended and Restated Certificate of
     Incorporation, as amended, 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 members of the Board of Directors
     of the Company 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 members of the Board of Directors
     of the Company 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 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
     stockholder 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


                                       17

<PAGE>


     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. 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 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.


                                       18

<PAGE>


          (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 dividend out of
the earnings or retained earnings of the Company as specified in Section 1(a) of
the Certificate of Designation establishing and designating the Preferred Shares
(a "Regular Dividend")), assets (other than a Regular Dividend 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) 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 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 such date; provided, however, that in the event that the current
     market price 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


                                       19

     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 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
     100 (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
     100.


                                       20

<PAGE>


          (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-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


                                       21

<PAGE>


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
ten-thousandth 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 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.

          (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


                                       22

<PAGE>


effect prior to such adjustment; provided, however, that the Company shall
deliver to such holder a due bill or other appropriate instrument evidencing
such holder's right to receive such additional shares (fractional or otherwise)
or securities upon the occurrence of the event requiring such adjustment.

          (m) Anything in this Section 11 to the contrary notwithstanding, the
Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that in their good faith judgment 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 or 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
stockholders.

          (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 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 stockholders of the Person who
constitutes, or would constitute, the "Principal Party" for purposes of Section
13(a) hereof shall have received a distribution of Rights previously owned by
such Person or any of its Affiliates 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


                                       23

<PAGE>


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 members of
the Board of Directors of the Company, may permit the Rights, subject to Section
7(e) hereof, to be exercised for 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 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
cancelled.

     Section 12. Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an adjustment is made as provided in Section 11 and Section 13 hereof,
the Company shall (a) promptly prepare a certificate setting forth such
adjustment and a brief statement of the facts accounting for such adjustment,
(b) promptly file with the Rights Agent, and with each transfer agent for the
Preferred 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.

     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


                                       24

<PAGE>


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 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, nonassessable and freely tradeable Common 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 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
     (2) 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


                                       25

<PAGE>


          (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 any such case, (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; and


                                       26

<PAGE>


          (ii) will 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 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
tender offer or exchange offer for all outstanding Common Shares that complies
with the provisions of Section 11(a)(ii)(B) hereof (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 members of the Board of Directors of the Company, may agree with the
Principal Party that the Principal Party shall permit the Rights to be exercised
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 cancelled.

          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


                                       27

<PAGE>


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
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) 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.


                                       28

     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 principal office or offices 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, subject to the last sentence of
Section 7(e) hereof, shall be required to be affected by any notice to the
contrary; and

          (d) notwithstanding anything in this Agreement to the contrary,
neither the Company nor the Rights Agent shall have any liability to any holder
of a Right or 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 or ruling
issued by a court of competent jurisdiction or by


                                       29

<PAGE>


a governmental, regulatory or administrative agency or commission, or any
statute, rule, regulation or executive order promulgated or enacted by any
governmental authority, prohibiting or otherwise restraining performance of such
obligation; provided, however, the Company must use its best efforts to have any
such order, decree or ruling lifted or otherwise overturned as soon as possible.

     Section 17. Rights Certificate Holder Not Deemed a Stockholder. No holder,
as such, of any Rights Certificate shall be entitled to vote, receive dividends
or be deemed for any purpose the holder of the number of 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 stockholder of the Company or any right to vote for the election
of directors or upon any matter submitted to stockholders at any meeting
thereof, or to give or withhold consent to any corporate action, or to receive
notice of meetings or other actions affecting stockholders (except as provided
in 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 administration and
execution of this Agreement and the exercise and performance of its duties
hereunder. The Company also agrees to indemnify the Rights Agent, for and to
hold it harmless against, any loss, liability, or expense, incurred without
negligence, bad faith or willful misconduct on the part of the Rights Agent, for
anything done or omitted by the Rights Agent in connection with the acceptance
and administration of this Agreement, including the costs and expenses of
defending against any claim of liability in the premises.

          (b) The Rights Agent shall be protected and shall incur no liability
for or in respect of any action taken, suffered or omitted by it in connection
with its administration of this Agreement in reliance upon any 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 corporation into which the Rights Agent or any successor
Rights Agent may be merged or with which it may be consolidated, or any
corporation resulting from any merger or consolidation to which the Rights Agent
or any successor Rights Agent shall be a party, or any corporation succeeding to
the corporate trust or 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 corporation
would be eligible for appointment as a successor Rights Agent under the
provisions of Section 21 hereof. In case at the time such successor Rights Agent
shall succeed to the agency 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.

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

     Section 20. Duties of Rights Agent. The Rights Agent undertakes the duties
and obligations imposed by this Agreement upon the following terms and
conditions, by all of which the Company and the holders of Rights Certificates
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 written opinion of such counsel shall be full
and complete authorization and protection to the Rights Agent as to any action
taken or omitted by it in good faith and in accordance with such opinion.

          (b) Whenever in the performance of its duties under this Agreement the
Rights Agent shall deem it necessary or desirable that any fact or matter
(including, without limitation, the identity of any Acquiring Person and the
determination of "current market price") be proved or established by the Company
prior to taking or suffering any


                                       31

<PAGE>


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 to the Rights Agent for any action taken
or suffered in good faith by it under the provisions of this Agreement in
reliance upon such certificate.

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

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

          (e) The Rights Agent shall not be under any responsibility in respect
of the validity of this Agreement or the execution and delivery hereof (except
the due execution hereof by the Rights Agent) or in respect of the validity or
execution of any Rights Certificate (except its countersignature thereof); nor
shall it be responsible for any breach by the Company of any covenant or
condition contained in this Agreement or in any Rights Certificate; nor shall it
be responsible for any adjustment required under the provisions of Section 11 or
Section 13 hereof 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 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 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 it shall not be liable for any action


                                       32

<PAGE>


taken or suffered to be taken by it in good faith in accordance with
instructions of any such officer.

          (h) The Rights Agent and any stockholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the Company or become pecuniarily interested in any transaction in
which the Company may be interested, or contract with or lend money to the
Company 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 legal entity.

          (i) The Rights Agent may execute and exercise any of the rights or
powers hereby vested in it or perform any duty hereunder either itself or by or
through its attorneys or agents, and the Rights Agent shall not be answerable or
accountable for any act, default, neglect or misconduct of any such attorneys or
agents or for any loss to the Company resulting from any such act, default,
neglect or misconduct; provided, however, reasonable care was exercised 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
there shall be reasonable grounds for believing that repayment of such funds or
adequate indemnification against such risk or liability is not reasonably
assured to it.

          (k) If, with respect to any Rights Certificate surrendered to the
Rights Agent for exercise or transfer, the certificate attached to the form of
assignment or form of election to purchase, as the case may be, has either not
been completed 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


                                       33

<PAGE>


resignation or incapacity by the resigning or incapacitated Rights Agent or by
the holder of a Rights Certificate (who shall, with such notice, submit his
Rights Certificate for inspection by the Company), then any registered holder of
any Rights Certificate may apply to any court of competent jurisdiction for the
appointment of a new Rights Agent. Any successor Rights Agent, whether appointed
by the Company or by such a court, shall be (a) a corporation organized, 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 corporate trust 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 adequate in the judgment of a majority of the members of the
Board of Directors of the Company to assure the performance of its duties
hereunder and the protection of the interests of the Company and the holders of
Rights or beneficial interests therein, or (b) an Affiliate of a corporation
described in clause (a) of this sentence. 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. Failure to give any notice provided for in this Section 21, however, or
any defect therein, shall not affect the legality or validity of the resignation
or removal of the Rights Agent or the appointment of the successor Rights Agent,
as the case may be.

     Section 22. Issuance of New Rights Certificates. Notwithstanding any of the
provisions of this Agreement or of the Rights to the contrary, the Company may,
at its option, issue new Rights Certificates evidencing Rights in such form as
may be approved by its Board of Directors to reflect any adjustment or change in
the Purchase Price and the number or kind or class of shares or other securities
or property purchasable under the Rights Certificates made in accordance with
the provisions of this Agreement. 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


                                       34

<PAGE>


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 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, 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 the members of the Board of Directors of the
Company) 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, evidence of which shall have been
filed with the Rights Agent and without any further action and without any
notice, the right to exercise the Rights will terminate and the only right
thereafter of the holders of Rights shall be to receive the Redemption Price for
each Right so held. 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 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


                                       35

<PAGE>


such notice of redemption will state the method by which the payment of the
Redemption Price will be made.

          (c) In deciding whether or not to exercise the Company's right of
redemption hereunder, the directors of the Company shall act in good faith, in a
manner they reasonably believe to be in the best interests of the Company and
with such care, including reasonable inquiry, skill and diligence, as a person
of ordinary prudence would use under similar circumstances.

     Section 24. Notice of Certain Events.

          (a) In case the Company shall propose, at any time after the
Distribution Date, (i) to pay any dividend payable in stock of any class to the
holders of Preferred Shares or to make any other distribution to the holders of
Preferred Shares (other than a Regular Dividend), 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 each
holder of a Rights Certificate, to the extent feasible and in accordance with
Section 25 hereof, a notice of such proposed action, which shall specify the
record date for the purposes of such stock dividend, distribution of rights or
warrants, or the date on which such reclassification, consolidation, merger,
sale, transfer, liquidation, dissolution, or winding up is to take place and the
date of participation therein by the holders of 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 Right, to the
extent feasible and in accordance with Section 25 hereof, a notice of the
occurrence of such event, which shall specify the event and the consequences of
the event to holders of Rights under Section


                                       36

<PAGE>


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 25. 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 first-class
mail, postage prepaid, addressed (until another address is filed in writing with
the Rights Agent) as follows:

                   Attention: Corporate Secretary

Subject to the provisions of Section 21, any notice or demand authorized by this
Agreement to be given or made by the Company or by the holder of any Rights
Certificate to or on the Rights Agent shall be sufficiently given or made if
sent by first-class mail, postage prepaid, addressed (until another address is

                   New York, NY 10005
                   Attention: Corporate Trust Department

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

     Section 26. Supplements and Amendments.

          (a) Prior to the Distribution Date and subject to the penultimate
sentence of this Section 26, the Company and the Rights Agent shall, if the
Company so directs, supplement or amend any provision of this Agreement without
the approval of any holders of certificates representing Common Shares. From and
after the Distribution Date and subject to the penultimate sentence of this
Section 26, the Company and the Rights Agent shall, if the Company so directs,
supplement or amend this Agreement without the approval of any holders of Rights
Certificates in order (i) to cure any ambiguity, (ii) to correct or supplement
any provision contained herein which may be defective or inconsistent with any
other provisions herein, (iii) to shorten or lengthen any time period hereunder,
or (iv) to change or supplement the provisions hereunder in any manner that the
Company may deem necessary or desirable and that shall not adversely affect the
interests of the holders of Rights Certificates; provided, this Agreement may
not be supplemented or amended to


                                       37

<PAGE>


lengthen, pursuant to clause (iii) of this sentence, (A) a time period relating
to when the Rights may be redeemed at such time as the Rights are not then
redeemable, or (B) any other time period unless such lengthening is for the
purpose of protecting, enhancing or clarifying the rights of, and/or the
benefits to, the holders of Rights. Upon the delivery of a certificate from an
appropriate officer of the Company that states that the proposed supplement or
amendment is in compliance with the terms of this Section 26, the Rights Agent
shall execute such supplement or amendment. Notwithstanding anything contained
in this Agreement to the contrary, no supplement or amendment shall be made that
changes the Redemption Price, the Final Expiration Date, the Purchase Price or
the number of Preferred Share Fractions for which a Right is exercisable. 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.

          (b) In deciding whether or not to supplement or amend this Agreement,
the directors of the Company shall act in good faith, in a manner they
reasonably believe to be in the best interests of the Company and with such
care, including reasonable inquiry, skill and diligence, as a person of ordinary
prudence would use under similar circumstances, and they may consider the
effects of any action upon employees, suppliers and customers of the Company and
upon communities in which offices or other establishments of the Company are
located, and all other pertinent factors.

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

     Section 28. 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 shall have the exclusive power and authority
to administer this Agreement and to exercise all rights and powers specifically
granted to the Board 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 with respect to the foregoing) that are done or made by the Board
in good faith, shall (x) be final, conclusive and binding on the Company, the
Rights Agent, the holders of the Rights and all other parties, and (y) not
subject the Board to any liability to the holders of the Rights.


                                       38

     Section 29. Benefits of this Agreement. Nothing in this Agreement shall be
construed to give to any Person other than the Company, the Rights Agent and the
registered holders of the Rights Certificates (and, prior to the Distribution
Date, registered holders of 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 30. Severability. If any term, provision, covenant or restriction
of this Agreement is held by a court of competent jurisdiction or other
authority to be invalid, void or unenforceable 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 31. 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 State of Delaware and for all purposes shall be governed by and
construed in accordance with the laws of such jurisdiction applicable to
contracts made and to be performed entirely within such jurisdiction.

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

     Section 33. Descriptive Headings. Descriptive headings of the several
Sections of this Agreement are inserted for convenience only and shall not
control or affect the meaning or construction of any of the provisions hereof.

                     RESOLUTION OF THE BOARD OF DIRECTORS OF
                            NEOSE TECHNOLOGIES, INC.
                           ESTABLISHING & 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 Neose Technologies, Inc. (the "Corporation") by ARTICLE V of the
Second Amended and Restated Certificate 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 Preferred Stock, par value $.01 per share, which shall consist of 300,000
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) Dividends shall be payable on the Series A Preferred Shares on
such payment date as shall be specified by the Board of Directors (each such
date being referred to herein as a "Dividend Payment Date"), in an amount per
share (rounded to the nearest cent) equal to, subject to the provision for
adjustment hereinafter set forth, 100 times the aggregate per share amount of
all cash dividends, and 100 times the aggregate per share amount (payable in
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 of the Corporation since the immediately preceding Dividend Payment
Date, or, with respect to the first Dividend Payment Date, since the first
issuance of any share or fraction of a share of 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
October 6, 1997 (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 is the number
of shares of Common Stock outstanding


<PAGE>


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 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 Dividend Payment Date, in which
case dividends on such shares shall begin to accrue from the date of issue of
such shares, or unless the date of issue is a Dividend Payment Date or is a date
after the record date for the determination of holders of Series A Preferred
Shares entitled to receive a dividend and before such Dividend Payment Date, in
either of which events such dividends shall begin to accrue and be cumulative
from such 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 100 votes on
all matters submitted to a vote of the stockholders of the Corporation. In the
event the Corporation shall at any time after the Rights Declaration Date (i)
declare any dividend on 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 for two successive Dividend Payment Dates and such dividends
shall not have been paid by the 60th day after the second Dividend Payment Date,
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 stockholders'
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 stockholders 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


                                       2

<PAGE>


holders of shares of such series shall cease, 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 stockholders 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 stockholders 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 stockholders 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 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 Certificate 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)


                                       3

shall vote together as one class on all matters submitted to a vote of
stockholders 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 cancelled promptly after the acquisition thereof. All such shares
shall upon their cancellation become authorized but unissued Preferred Stock and
may be reissued as part of a new series of Preferred Stock to be created by
resolution or resolutions of the Board of Directors.

          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) $1.00 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 100
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 100 times the aggregate amount of stock, securities, cash and/or any
other property (payable in kind), as the case may be, into which or for which
each share of Common Stock is changed or exchanged. In the event the Corporation
shall at any time 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 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
Amended and Restated Rights Agreement, dated as of December 3, 1998 (the "Rights
Agreement"), between Neose Technologies, Inc., a Delaware corporation (the
"Company"), and American Stock Transfer & Trust Company, a New York banking
corporation (the "Rights Agent"), to purchase from the Company at any time prior
to 5:00 P.M. (New York, New York time) on October 6, 2007 at the office or
offices of the Rights Agent designated for such purpose, or its successors as
Rights Agent, one one-hundredth of a fully paid, nonassessable Series A Junior
Participating Preferred Share (the "Preferred Share") of the Company, at a
purchase price (the "Purchase Price") of $150.00 per one one-hundredth 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 in cash. 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 October 6, 1997, 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 an Affiliate or Associate of any such
Acquiring Person (as such terms are defined in the Rights Agreement), (ii) a
transferee of any such Acquiring Person, Associate or Affiliate, 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.

     This Rights Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated


<PAGE>


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 principal office or offices 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 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
members of the Board of Directors of the Company.

                  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 stockholder of the Company or any right to vote for
the election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action, or, to
receive notice of meetings or other actions affecting stockholders (except as
provided in the Rights Agreement), or to receive dividends 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.

                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES

     On September 17, 1997, the Board of Directors of Neose Technologies, Inc.
(the "Company") declared a dividend distribution of one Right for each
outstanding share of Common Stock, $.01 par value (each, a "Common Share"), of
the Company to stockholders of record at the close of business on October 6,
1997. Each Right entitles the registered holder to purchase from the Company a
unit consisting of one one-hundredth of a share (a "Unit") of the Series A
Junior Participating Preferred Shares, par value $.01 per share, of the Company
(the "Preferred Shares"), or a combination of securities and assets of
equivalent value, at a Purchase Price of $150.00 per Unit, subject to
adjustment. On December 3, 1998, the Board of Directors of the Company, in
accordance with the terms set forth in Section 26 of the Rights Agreement dated
as of September 26, 1997 between the Company and American Stock Transfer & Trust
Company, as Rights Agent, approved the amendment and restatement of the Rights
Agreement effective as of December 3, 1998 (as so amended and restated, the
"Rights Agreement"). The description and terms of the Rights are set forth in
the Rights Agreement.

     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 upon the earlier of (i) 10 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 15% or more of the outstanding Common Shares
(the "Stock Acquisition Date"), or (ii) the close of business on such date as
may be fixed by the Board of Directors, which date shall not be more than 65
days following the commencement of a tender offer or exchange offer that would
result in a person or group beneficially owning 15% or more of the outstanding
Common Shares. Until the Distribution Date, (i) the Rights will be evidenced by
the Common Share certificates and will be transferred with and only with such
Common Share certificates, (ii) new Common Share certificates issued after
October 6, 1997 will contain a notation incorporating the Rights Agreement by
reference and (iii) 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 October 6, 2007, 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


<PAGE>


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 October 6, 1997 and prior to the Distribution Date will be
issued with Rights.

     Except in the circumstances described below, after the Distribution Date
each Right will be exercisable for one one-hundredth 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., 100 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 becomes the beneficial owner
of more than 15% of the then outstanding Common Shares other than pursuant to a
tender offer that provides fair value to all stockholders, (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 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 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 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 $150.00 per Right, each Right not
otherwise voided following an event set forth in the preceding paragraph would
entitle its holder to purchase $300.00 worth of Common Shares (or other
consideration, as noted above) for $150.00. Assuming that the Common Shares had
a per share value of $50 at such time, the holder of each valid Right would be
entitled to purchase six Common Shares for $150.00. 


                                       2

<PAGE>


Alternatively, the Company could permit the holder to surrender each Right in
exchange for stock or cash equivalent to three Common Shares (with a value of
$150.00) 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 is
described in, or that follows a tender offer or exchange offer described in, the
second preceding paragraph), 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 two times the exercise price of the Right. Again, provision is made to
permit 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 Dividends) or of subscription rights or warrants
(other than those referred to above).

     With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments amount to at least 1% of the Purchase
Price. 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. Immediately upon the action of the
Board of Directors ordering redemption of the Rights, the Rights will terminate
and the only right of the holders of Rights will be to receive the $.01
redemption price.

     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


                                       3

<PAGE>


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 the principal economic terms of the
Rights, 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 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 a Current Report on Form 8-K. A copy of the
Rights Agreement is available free of charge from the Company. 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.
