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

     On January 22, 1999, AeroCentury Corp. (the "Company") amended and restated
its Rights  Agreement,  dated as of April 8, 1998 (the "Rights  Agreement"),  to
eliminate  those  provisions that require that certain actions may only be taken
by "Independent  Directors." This Amended and Restated Rights Agreement was made
in response to the Delaware  Court of Chancery's  recent  decision in Carmody v.
Toll Brothers,  Inc. In the view of the Company's  Board of Directors,  based on
advice of  counsel,  the Toll  Brothers,  Inc.  decision  has cast  doubt on the
legality under Delaware law of so-called "dead-hand" provisions in many existing
shareholder rights plans. Although the opinion related to the denial of a motion
to dismiss an action  challenging the  "dead-hand"  provision and not an opinion
addressing the actual validity of the provision under Delaware law, the Delaware
court stated that a "dead-hand"  provision was open to challenge  under Delaware
law on both statutory and fiduciary grounds. A so-called  "dead-hand"  provision
is a provision  which provides that  outstanding  rights can only be redeemed by
"independent  directors,"  which is generally defined to mean directors who were
members of the board at the time the Rights  Agreement was adopted and any other
person  who  subsequently  becomes  a  member  of the  board  if  such  person's
nomination  for election to the board was  recommended or approved by a majority
of the independent directors.  While the Company's Rights Agreement differs from
the plan  considered in the Toll Brothers case,  particularly  as regards to the
"Independent  Directors" provisions thereof, the Board of Directors believes the
disputed  validity of these  provisions under the Toll Brothers opinion warrants
action to amend the Rights Agreement.  The Amended and Restated Rights Agreement
is attached hereto as an exhibit and is incorporated by reference herein.

                   FIRST AMENDED AND RESTATED RIGHTS AGREEMENT

     FIRST AMENDED AND RESTATED RIGHTS  AGREEMENT,  dated as of January __, 1998
(the  "Agreement"),  between  AeroCentury  Corp.,  a Delaware  corporation  (the
"Company"),  and  Continental  Stock  Transfer  &  Trust  Company,  a  New  York
corporation (the "Rights Agent+).

     WHEREAS,  effective April 8, 1998 (the "Rights Dividend Declaration Date"),
the Board of  Directors  of the Company (i)  authorized  and declared a dividend
distribution  of one Right for each share of Common  Stock,  par value $.001 per
share, of the Company (the "Company  Common Stock")  outstanding at the Close of
Business on April 23, 1998 (the "Record Date"), and (ii) authorized the issuance
of one Right (as such number may  hereinafter be adjusted  pursuant  hereto) for
each share of Company  Common  Stock  issued  between the Record  Date  (whether
originally  issued or delivered  from the  Company's  treasury)  and,  except as
otherwise  provided in Section 22, the  Distribution  Date, each Right initially
representing  the right to purchase upon the terms and subject to the conditions
hereinafter set forth one Unit of Series A Preferred Stock (the "Rights"); and

     WHEREAS,  the Board of  Directors  of the Company and the Rights Agent have
determined that it is in the best interest of the Company and the holders of the
Company  Common  Stock to amend the  Agreement  with  respect to the  provisions
governing supplements and amendments to the Agreement;

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

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

     (a)  "Acquiring  Person" shall mean any Person who or which,  together with
all Affiliates or Associates of such Person,  shall be the  Beneficial  Owner of
15%  or  more  of  the  shares  of  Company   Common  Stock  then   outstanding.
Notwithstanding the foregoing:  (i) an "Acquiring Person" shall not include: (A)
the Company;  (B) any Subsidiary of the Company;  (C) any employee  benefit plan
maintained  by the  Company  or any of its  Subsidiaries;  (D)  any  trustee  or
fiduciary with respect to such employee  benefit plan acting in such capacity or
a trustee or fiduciary holding shares of Company Common Stock for the purpose of
funding any such plan or employee  benefits;  (E) any Person who has reported or
is required to report such ownership on Schedule 13G  under the Exchange Act (or
any  comparable  or successor  report),  but only so long as (x) such  Person is
eligible to report such ownership on  Schedule 13(G)  under the Exchange Act (or
any comparable or successor report), (y) such Person has not reported and is not
required to report such ownership on  Schedule 13(D)  under the Exchange Act (or
any comparable or successor  report),  and (z) such Person does not beneficially
own 20% or more of the shares of Company Common Stock then outstanding;  (F) any
Person if the Board of  Directors of the Company  determines  in good faith that
such  Person  who  would   otherwise  be  an  "Acquiring   Person"  became  such
inadvertently  (including,  without  limitation,  because  (x) such  Person  was
unaware that it  beneficially  owned a percentage  of Company  Common Stock that
would otherwise cause such Person to be an "Acquiring Person" or (y) such Person
was aware of the extent of its Beneficial  Ownership of Company Common Stock but
had no actual knowledge of the  consequences of such Beneficial  Ownership under
this Agreement) and without any intention of changing or influencing  control of
the  Company,  and if such  Person does not  acquire  any  additional  shares of
Company Common Stock and as promptly as  practicable  divested or divests itself
of Beneficial Ownership of a sufficient number of shares of Company Common Stock
so that such Person would no longer be an "Acquiring  Person;" or (G) any Person
who becomes the Beneficial Owner of 15% or more of the then  outstanding  shares
of  Company  Common  Stock as a result of the  acquisition  of shares of Company
Common Stock directly from the Company in one or more transactions approved by a
majority  of the  Board of  Directors,  and (ii) no  Person  shall be  deemed an
"Acquiring  Person" as a result of the  acquisition  of shares of Company Common
Stock by the Company  which,  by reducing the number of shares of Company Common
Stock  outstanding,  increases the  proportional  number of shares  beneficially
owned by such Person;  provided,  however,  that if (A) a Person would become an
Acquiring  Person (but for the operation of this subclause  (ii)) as a result of
the  acquisition  of shares of Company Common Stock by the Company and (B) after
such share acquisition by the Company,  such Person becomes the Beneficial Owner
of any  additional  shares of Company  Common  Stock,  then such Person shall be
deemed an Acquiring  Person  unless upon becoming the  Beneficial  Owner of such
additional  shares such Person is the  Beneficial  Owner of less than 15% of the
then  outstanding  shares of Company  Common  Stock.  Each Person  identified in
subclauses  (A),  (B), (C) and (D) of this  Section  (1)(a) is  individually  an
"Exempt Person" and collectively "Exempt Persons."

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

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

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

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

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

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

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

     (f)  "Common  Stock" of any Person  other than the  Company  shall mean the
capital stock of such Person with the greatest voting power,  or, if such Person
shall have no capital  stock,  the equity  securities  or other equity  interest
having power to control or direct the management of such Person.

and (ii) the Close of Business on the tenth  Business Day (or such later date as
may be  determined  by action of a  majority  of the Board of  Directors  of the
Company  prior to the  occurrence of a Section  11(a)(ii)  Event) after the date
that a tender or exchange  offer by any Person (other than an Exempt  Person) is
first  published  or sent or given  within the meaning of  Rule 14d-4(a)  of the
Exchange Act  Regulations or any successor  rule, if upon  consummation  thereof
such Person would be an Acquiring Person (including,  in the case of both clause
(i) and (ii),  any such date which is after the date of this Agreement and prior
to the  issuance  of the  Rights)(the  earlier of (i) and (ii)  above  being the
"Distribution  Date"),  (x)  the  Rights  will  be  evidenced  (subject  to  the
provisions of paragraph (b) of this Section 3) by the certificates for shares of
Company Common Stock registered in the names of the holders of shares of Company
Common Stock as of and  subsequent  to the Record Date (which  certificates  for
shares of Company  Common  Stock  shall be deemed  also to be  certificates  for
Rights)  and  not  by  separate  certificates,   and  (y)  the  Rights  will  be
transferable  only in connection  with the transfer of the underlying  shares of
Company  Common Stock  including a transfer to the Company;  provided,  however,
that if a tender or exchange  offer is terminated  prior to the  occurrence of a
Distribution  Date,  then no  Distribution  Date shall occur as a result of such
tender or exchange offer. As soon as practicable  after the  Distribution  Date,
the Rights Agent will send by  first-class,  insured,  postage  prepaid mail, to
each record holder of shares of Company Common Stock as of the Close of Business
on the Distribution  Date, at the address of such holder shown on the records of
the  Company,  one or more rights  certificates,  in  substantially  the form of
Exhibit A hereto  (the  "Rights  Certificates"),  evidencing  one Right for each
share of Company Common Stock so held, subject to adjustment as provided herein.

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

     (b) As promptly as practicable  following the Record Date, the Company will
send a copy of a Summary of Rights to Purchase Preferred Stock, in substantially
the form attached hereto as Exhibit B (the "Summary of Rights"), by first-class,
postage prepaid mail, to each record holder of shares of Company Common Stock as
of the Close of Business on the Record Date, at the address of such holder shown
on the records of the Company.  With respect to certificates  for Company Common
Stock outstanding as of the Record Date, until the Distribution Date, the Rights
will be evidenced by such  certificates  registered  in the names of the holders
thereof together with the Summary of Rights. Until the Distribution Date (or, if
earlier,   the  Expiration  Date),  the  surrender  for  transfer  of  any  such
certificate for Company Common Stock  outstanding as of the Record Date, with or
without a copy of the Summary of Rights,  shall also  constitute the transfer of
the Rights associated with the Company Common Stock represented thereby.

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

     This  certificate  also evidences and entitles the holder hereof to certain
Rights as set forth in the  Rights  Agreement  between  AeroCentury  Corp.  (the
"Company") and  Continental  Stock Transfer & Trust Company (the "Rights Agent")
dated  as  of  April 8,  1998,  as  amended  from  time  to  time  (the  "Rights
Agreement"),  the terms of which are hereby incorporated herein by reference and
a copy of  which  is on file  at the  principal  office  of the  stock  transfer
administration office of the Rights Agent. Under certain  circumstances,  as set
forth in the  Rights  Agreement,  such  Rights  will be  evidenced  by  separate
certificates  and will no longer be evidenced by this  certificate.  The Company
will mail to the holder of this certificate a copy of the Rights  Agreement,  as
in effect on the date of mailing,  without  charge  promptly  after receipt of a
written request  therefor.  UNDER CERTAIN  CIRCUMSTANCES SET FORTH IN THE RIGHTS
AGREEMENT,  RIGHTS  ISSUED  TO, OR HELD BY, ANY PERSON WHO IS, WAS OR BECOMES AN
ACQUIRING  PERSON OR ANY  AFFILIATE  OR  ASSOCIATE  THEREOF  (AS SUCH  TERMS ARE
DEFINED IN THE RIGHTS AGREEMENT), WHETHER CURRENTLY HELD BY OR ON BEHALF OF SUCH
PERSON OR BY ANY SUBSEQUENT HOLDER, MAY BECOME NULL AND VOID.

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

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

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

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

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

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

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

     (b) The purchase price for each one one-hundredth of a share (each such one
one-hundredth  of a share being a "Unit") of  Preferred  Stock upon  exercise of
Rights shall be $66.00,  subject to adjustment  from time to time as provided in
Sections 11 and 13(a) hereof (such  purchase  price,  as so adjusted,  being the
"Purchase Price"), and shall be payable in accordance with paragraph (c) below.

     (c) As promptly as practicable following the occurrence of the Distribution
Date,  the Company shall deposit with the Rights Agent or other  corporation  in
good standing  organized under the laws of the United States or any State of the
United States,  which is authorized under such laws to exercise  corporate trust
or stock transfer powers and is subject to supervision or examination by federal
or state authority (such institution being the "Depositary Agent"), certificates
representing the shares of Preferred Stock that may be acquired upon exercise of
the Rights  and shall  cause such  Depositary  Agent to enter into an  agreement
pursuant  to which  the  Depositary  Agent  shall  issue  receipts  representing
interests  in the shares of  Preferred  Stock so  deposited.  Upon  receipt of a
Rights Certificate representing exercisable Rights, with the form of election to
purchase and the certificate duly executed, accompanied by payment, with respect
to each Right so  exercised,  of the  Purchase  Price for the Units of Preferred
Stock (or, following a Triggering Event, other securities, cash or other assets,
as the case may be) to be  purchased  thereby  as set forth  below and an amount
equal to any applicable transfer tax or evidence  satisfactory to the Company of
payment of such tax, the Rights Agent shall,  subject to Section  20(k)  hereof,
thereupon promptly (i) requisition from the Depositary Agent depositary receipts
representing  such number of Units of Preferred Stock as are to be purchased and
the Company will direct the Depositary  Agent to comply with such request,  (ii)
requisition  from the Company the amount of cash,  if any, to be paid in lieu of
fractional  shares in accordance with Section 14 hereof,  (iii) after receipt of
such depositary receipts, cause the same to be delivered to or upon the order of
the  registered  holder of such Rights  Certificate,  registered in such name or
names as may be  designated  by such  holder,  and (iv) after  receipt  thereof,
deliver such cash, if any, to or upon the order of the registered holder of such
Rights Certificate.  In the event that the Company is obligated to issue Company
Common Stock, other securities of the Company,  pay cash and/or distribute other
property   pursuant  to  Section  11(a)  hereof,   the  Company  will  make  all
arrangements necessary so that such Company Common Stock, other securities, cash
and/or other property are available for distribution by the Rights Agent, if and
when  appropriate.  The  payment of the  Purchase  Price (as such  amount may be
reduced  pursuant  to  Section  11(a)(iii)  hereof)  may be  made  in cash or by
certified or bank check or money order payable to the order of the Company.

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

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

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

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

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

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

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

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

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

     Section 10.  Preferred  Stock  Record  Date.  Each Person in whose name any
certificate or depositary  receipt for Units of Preferred  Stock (or,  following
the  occurrence  of a Triggering  Event,  other  securities)  is issued upon the
exercise of Rights shall for all purposes be deemed to have become the holder of
record of the Units of  Preferred  Stock  (or,  following  the  occurrence  of a
Triggering Event, other securities) represented thereby on, and such certificate
shall be dated,  the date upon  which the  Rights  Certificate  evidencing  such
Rights  was  duly  surrendered  and  payment  of the  Purchase  Price  (and  any
applicable transfer taxes) was made; provided, however, that if the date of such
surrender  and payment is a date upon which the Preferred  Stock (or,  following
the occurrence of a Triggering Event,  other  securities)  transfer books of the
Company are closed, such Person shall be deemed to have become the record holder
of such securities on, and such certificate  shall be dated, the next succeeding
Business Day on which the Preferred  Stock (or,  following  the  occurrence of a
Triggering Event, other securities)  transfer books of the Company are open and,
further  provided,  however,  that if  delivery of Units of  Preferred  Stock is
delayed  pursuant to Section 9(c) hereof,  such Persons  shall be deemed to have
become the record holders of such Units of Preferred  Stock only when such Units
first become deliverable. Prior to the exercise of the Rights evidenced thereby,
the  holder of a Rights  Certificate  shall not be  entitled  to any rights of a
stockholder of the Company with respect to securities for which the Rights shall
be exercisable,  including,  without  limitation,  the right to vote, to receive
dividends or other distributions or to exercise any preemptive rights, and shall
not be entitled to receive any notice of any proceedings of the Company,  except
as provided herein.

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

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

     (ii) In the event any Person shall become an Acquiring  Person,  other than
pursuant to any transaction set forth in Section 13(a) hereof, then, immediately
upon  the  occurrence  of such  event  (a "Section  11(a)(ii)  Event"),  proper
provision shall be made so that each holder of a Right (except as provided below
and in Section 7(e) hereof) shall, subject to Section 34 hereof, thereafter have
the right to receive,  upon exercise of such Right at the then current  Purchase
Price in accordance with the terms of this  Agreement,  in lieu of the number of
Units of Preferred Stock for which a Right was exercisable  immediately prior to
the first occurrence of a Section 11(a)(ii) Event (whether or not such Right was
then  exercisable),  such number of Units of Preferred  Stock as shall equal the
result obtained by (x)  multiplying the then current  Purchase Price by the then
number of Units of Preferred Stock for which a Right was exercisable immediately
prior to the first occurrence of a Section  11(a)(ii) Event (whether or not such
Right was then exercisable)  (such product thereafter being, for all purposes of
this Agreement,  other than Section 13 hereof,  the "Purchase  Price"),  and (y)
dividing  that  product  by 50% of the then  current  market  price  (determined
pursuant to Section  11(d)  hereof) per Unit of  Preferred  Stock on the date of
such first  occurrence  (such Units of  Preferred  Stock  being the  "Adjustment
Shares");  provided, however, that the Purchase Price and the number of Units of
Preferred  Stock so  receivable  upon  exercise of a Right shall,  following the
Section  11(a)(ii)  Event,  be subject to further  adjustment as  appropriate in
accordance  with Section 11 hereof.  Notwithstanding  the foregoing,  the Rights
shall not be  exercisable  pursuant  to this  Section  11(a)(ii)  until the time
period  during  which the Rights may be  redeemed  pursuant to Section 23 hereof
shall have expired.

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

     (b) In case the Company shall fix a record date for the issuance of rights,
options  or  warrants  to all  holders  of  Preferred  Stock  entitling  them to
subscribe for or purchase (for a period expiring within forty-five calendar days
after  such  record  date)  shares  of   Preferred   Stock  (or  shares   having
substantially the same rights, privileges and preferences as shares of Preferred
Stock ("Equivalent  Preferred Stock")) or securities  convertible into Preferred
Stock or Equivalent  Preferred  Stock at a price per share of Preferred Stock or
per share of Equivalent Preferred Stock (or having a conversion price per share,
if a security  convertible  into Preferred Stock or Equivalent  Preferred Stock)
less than the current  market  price (as  determined  pursuant to Section  l1(d)
hereof) per share of Preferred  Stock on such record date, the Purchase Price to
be in effect  after such  record date shall be  determined  by  multiplying  the
Purchase  Price in effect  immediately  prior to such record date by a fraction,
the  numerator  of which  shall be the sum of the number of shares of  Preferred
Stock  outstanding  on such record  date plus the number of shares of  Preferred
Stock  which  the  aggregate  offering  price of the  total  number of shares of
Preferred Stock and/or  Equivalent  Preferred Stock so to be offered (and/or the
aggregate  initial  conversion  price  of the  convertible  securities  so to be
offered)  would purchase at such current  market price,  and the  denominator of
which  shall be the  number of shares of  Preferred  Stock  outstanding  on such
record  date plus the number of  additional  shares of  Preferred  Stock  and/or
Equivalent  Preferred Stock to be offered for  subscription or purchase (or into
which the convertible securities so to be offered are initially convertible). In
case such  subscription  price may be paid by delivery of consideration  part or
all of which may be in a form other than cash,  the value of such  consideration
shall be as  determined  in good faith by a majority of the Board of  Directors,
whose  determination  shall be  described  in a statement  filed with the Rights
Agent and shall be binding on the Rights  Agent and the  holders of the  Rights.
Shares of Preferred Stock owned by or held for the account of the Company or any
Subsidiary  shall  not be  deemed  outstanding  for  the  purpose  of  any  such
computation.  Such adjustment shall be made successively  whenever such a record
date is fixed, and in the event that such rights, options or warrants are not so
issued,  the  Purchase  Price shall be adjusted to be the  Purchase  Price which
would then be in effect if such record date had not been fixed.

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

     (d) (i) For the purpose of any computation  hereunder,  the "current market
price" per share of Company  Common  Stock or Common  Stock on any date shall be
deemed to be the  average of the daily  closing  prices per share of such shares
for the ten  consecutive  Trading  Days (as such  term is  hereinafter  defined)
immediately prior to such date; provided, however, if prior to the expiration of
such requisite ten Trading Day period the issuer announces either (A) a dividend
or distribution on such shares payable in such shares or securities  convertible
into such shares (other than the Rights), or (B) any subdivision, combination or
reclassification of such shares,  then,  following the ex-dividend date for such
dividend   or  the   record   date  for   such   subdivision,   combination   or
reclassification,  as the case  may be,  the  "current  market  price"  shall be
properly  adjusted to take into account such event.  The closing  price for each
day shall be, if the shares are  listed  and  admitted  to trading on a national
securities  exchange,  as reported  in the  principal  consolidated  transaction
reporting  system with respect to securities  listed on the  principal  national
securities  exchange  on which such shares are listed or admitted to trading or,
if such shares are not listed or admitted to trading on any national  securities
exchange,  the last quoted  price or, if not so quoted,  the average of the high
bid and low asked  prices in the  over-the-counter  market,  as  reported by the
Nasdaq  National  Market  ("Nasdaq") or such other system then in use, or, if on
any such date such shares are not quoted by any such  organization,  the average
of the closing bid and asked prices as furnished by a professional  market maker
making a market in such shares selected by a majority of the Board of Directors.
If on any such date no market maker is making a market in such shares,  the fair
value of such shares on such date as  determined  in good faith by a majority of
the Board of Directors  shall be used.  If such shares are not publicly  held or
not so listed or traded,  "current  market  price" per share shall mean the fair
value  per  share as  determined  in good  faith by a  majority  of the Board of
Directors,  whose determination shall be described in a statement filed with the
Rights Agent and shall be conclusive  for all  purposes.  The term "Trading Day"
shall mean,  if such  shares are listed or  admitted to trading on any  national
securities  exchange,  a day on which the principal national securities exchange
on  which  such  shares  are  listed  or  admitted  to  trading  is open for the
transaction  of  business  or, if such shares are not so listed or  admitted,  a
Business Day.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

     Section 13. Consolidation,  Merger or Sale or Transfer of Assets or Earning
Power.  (a) In the  event  that,  following  the first  occurrence  of a Section
11(a)(ii)  Event,   directly  or  indirectly,   either  (x)  the  Company  shall
consolidate  with, or merge with and into, any other Person (other than a wholly
owned  Subsidiary  of the Company in a transaction  which  complies with Section
11(o)  hereof),  and  the  Company  shall  not be the  continuing  or  surviving
corporation of such consolidation or merger, (y) any Person (other than a wholly
owned  Subsidiary  of the Company in a transaction  which  compiles with Section
11(o) hereof) shall  consolidate  with, or merge with or into, the Company,  and
the  Company  shall  be  the   continuing  or  surviving   corporation  of  such
consolidation  or merger and, in connection with such  consolidation  or merger,
all or part of the  outstanding  shares of Company Common Stock shall be changed
into or  exchanged  for stock or other  securities  of the  Company or any other
Person or cash or any other property, or (z) the Company shall sell or otherwise
transfer (or one or more of its Subsidiaries  shall sell or otherwise  transfer)
to any  Person or Persons  (other  than the  Company or any of its wholly  owned
Subsidiaries  in one or more  transactions  each of which  complies with Section
11(o) hereof), in one or more transactions,  assets or earning power aggregating
50% or more of the assets or earning  power of the Company and its  Subsidiaries
(taken as a whole) (any such event being a "Section  13  Event"),  then,  and in
each such case,  proper  provision  shall be made so that:  (i) each holder of a
Right,  (other  than Rights  which have become void as provided in  Section 7(e)
hereof),  shall thereafter have the right to receive,  upon the exercise thereof
at the then current  Purchase  Price,  in accordance  with this Agreement and in
lieu of Units of Preferred Stock or shares of Company Common Stock,  such number
of  validly  authorized  and  issued,  fully  paid,  non-assessable  and  freely
tradeable  shares  of  Common  Stock of the  Principal  Party  (as such  term is
hereinafter  defined),   which  shares  shall  not  be  subject  to  any  liens,
encumbrances,  rights of call or first refusal,  transfer  restrictions or other
adverse claims, as shall be equal to the result obtained by (1) multiplying  the
then current  Purchase Price by the number of Units of Preferred Stock for which
a Right is exercisable immediately prior to the first occurrence of a Section 13
Event  (or,  if a  Section  11(a)(ii)  Event  has  occurred  prior to the  first
occurrence of a Section 13 Event, multiplying the number of such Units for which
a Right would be  exercisable  hereunder but for the  occurrence of such Section
11(a)(ii) Event by the Purchase Price which would be in effect hereunder but for
such first occurrence) and (2) dividing that product (which, following the first
occurrence of a Section 13 Event, shall be the "Purchase Price" for all purposes
of this  Agreement) by 50% of the current marke't price (determined  pursuant to
Section 11(d) hereof) per share of the Common Stock of such  Principal  Party on
the date of consummation of such Section 13 Event,  provided,  however, that the
Purchase Price (as  theretofore  adjusted in accordance  with Section  11(a)(ii)
hereof)  and the  number of shares of Common  Stock of such  Principal  Party so
receivable  upon  exercise of a Right shall be subject to further  adjustment as
appropriate  in  accordance  with  Section  11(f)  hereof to reflect  any events
occurring  in respect  of the Common  Stock of such  Principal  Party  after the
occurrence of such Section 13 Event;  (ii) such Principal Party shall thereafter
be liable for, and shall  assume,  by virtue of such  Section 13 Event,  all the
obligations and duties of the Company pursuant to this Agreement; (iii) the term
"Company"  shall  thereafter be deemed to refer to such  Principal  Party in all
respects;  (iv) such Principal Party shall take such steps  (including,  but not
limited to, the reservation of a sufficient number of shares of its Common Stock
in accordance with Section 9  hereof) in connection with the consummation of any
such  transaction  as may be  necessary  to assure that the  provisions  of this
Agreement  shall  thereafter be  applicable,  as nearly as reasonably may be, in
relation to its shares of Common Stock thereafter  deliverable upon the exercise
of the Rights, to its shares of Common Stock; provided,  however, that, upon the
subsequent occurrence of any merger, consolidation, sale of all or substantially
all of the assets, recapitalization,  reclassification of shares, reorganization
or other  extraordinary  transaction  in respect of such Principal  Party,  each
holder of a Right shall  thereupon  be entitled to receive,  upon  exercise of a
Right and payment of the Purchase Price, such cash, shares, rights, warrants and
other  property which such holder would have been entitled to receive had it, at
the time of such transaction,  owned the shares of Common Stock of the Principal
Party  purchasable  upon the exercise of a Right, and such Principal Party shall
take such steps (including,  but not limited to, reservation of shares of stock)
as may be  necessary  to  permit  the  subsequent  exercise  of  the  Rights  in
accordance  with the terms hereof for such cash,  shares,  rights,  warrants and
other property;  and (v) the provisions of Section  11(a)(ii) hereof shall be of
no further effect following the first occurrence of any Section 13 Event.

     (b) "Principal Party"shall mean:

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

     (ii) in the case of any  transaction  described  in clause (z) of the first
sentence of  Section 13(a)  hereof,  the Person that is the party  receiving the
largest  portion of the assets or earning  power  transferred  pursuant  to such
transaction  or  transactions,  or,  if each  Person  that  is a  party  to such
transaction or  transactions  receives the same portion of the assets or earning
power transferred  pursuant to such transaction or transactions or if the Person
receiving  the  largest  portion  of the  assets  or  earning  power  cannot  be
determined, whichever Person the Common Stock of which has the highest aggregate
current market price (determined  pursuant to Section 11(d)  hereof);  provided,
however, that in any such case, (1) if the Common Stock of such Person is not at
such time and has not been continuously over the preceding  twelve-month  period
registered under Section 12 of the Exchange Act ("Registered  Common Stock"), or
such  Person is not a  corporation,  and such  Person  is a direct  or  indirect
Subsidiary  of another  Person that has  Registered  Common  Stock  outstanding,
"Principal  Party" shall refer to such other Person;  (2) if the Common Stock of
such Person is not Registered  Common Stock or such Person is not a corporation,
and such Person is a direct or indirect  Subsidiary of another Person but is not
a direct or indirect  Subsidiary of another Person which has  Registered  Common
Stock  outstanding,  "Principal Party" shall refer to the ultimate parent entity
of such  first-mentioned  Person;  (3) if the Common Stock of such Person is not
Registered Common Stock or such Person is not a corporation,  and such Person is
directly or indirectly  controlled  by more than one Person,  and one or more of
such other Persons has Registered  Common Stock  outstanding,  "Principal Party"
shall refer to whichever of such other  Persons is the issuer of the  Registered
Common  Stock having the highest  aggregate  current  market  price  (determined
pursuant to Section 11(d) hereof); and (4) if the Common Stock of such Person is
not Registered Common Stock or such Person is not a corporation, and such Person
is directly or indirectly  controlled by more than one Person,  and none of such
other Persons have Registered Common Stock outstanding, "Principal Party" shall
refer to whichever ultimate parent entity is the corporation having the greatest
shareholders  equity or, if no such  ultimate  parent  entity is a  corporation,
shall  refer to  whichever  ultimate  parent  entity is the  entity  having  the
greatest net assets

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

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

     (ii) as soon as  practicable  following  the  execution of such  agreement,
deliver  to  holders  of the  Rights  historical  financial  statements  for the
Principal Party and each of its Affiliates which comply in all respects with the
requirements for registration on Form 10 under the Exchange Act.

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

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

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

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

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

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

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

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

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

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

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

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

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

     (b) The Rights Agent shall be protected and shall incur no liability for or
in respect of any action taken, suffered or omitted by it in connection with its
administration  of this  Agreement in reliance  upon any Rights  Certificate  or
certificate  for  Preferred  Stock  or for  other  securities  of  the  Company,
instrument of assignment or transfer, power of attorney, endorsement, affidavit,
letter, notice,  direction,  consent,  certificate,  statement or other paper or
document  believed by it to be genuine and to have been  signed,  executed  and,
where necessary, verified or acknowledged by the proper Person or Persons.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

     (k) If, with respect to any Rights  Certificate  surrendered  to the Rights
Agent  for  exercise  or  transfer,  the  certificate  attached  to the  form of
assignment  or form of election to purchase,  as the case may be, has either not
been  completed,  not signed or  indicates an  affirmative  response to clause 1
and/or 2 thereof,  the  Rights  Agent  shall not take any  further  action  with
respect to such requested exercise or transfer without first consulting with the
Company.  If such certificate has been completed and signed and shows a negative
response to clauses 1 and 2 of such certificate,  unless  previously  instructed
otherwise in writing by the Company (which instructions may impose on the Rights
Agent   additional   ministerial   responsibilities,    but   no   discretionary
responsibilities),  the Rights Agent may assume without further inquiry that the
Rights Certificate is not owned by a Person described in Section 7(e) hereof and
shall not be charged with any knowledge to the contrary.

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

     Section 22. Issuance of New Rights Certificates. Notwithstanding any of the
provisions of this Agreement or the Rights to the contrary,  the Company may, at
its option, issue new Rights Certificates  evidencing Rights in such form as may
be approved by a majority of the Board of Directors to reflect any adjustment or
change made in accordance  with the provisions of this Agreement in the Purchase
Price or the number or kind or class of shares or other  securities  or property
that may be acquired under the Rights Certificates.  In addition,  in connection
with the  issuance  or sale of shares of  Company  Common  Stock  following  the
Distribution  Date and prior to the Expiration Date, the Company (a) shall, with
respect  to shares of Company  Common  Stock so issued or sold  pursuant  to the
exercise of stock options or under any employee plan or arrangement, or upon the
exercise,  conversion  or  exchange  of  securities  hereinafter  issued  by the
Company, and (b) may, in any other case, if deemed necessary or appropriate by a
majority of the Board of Directors,  issue Rights Certificates  representing the
appropriate number of Rights in connection with such issuance or sale; provided,
however,  that (i) no such  Rights  Certificate  shall be issued  if, and to the
extent that,  the Company shall be advised by counsel that such  issuance  would
create a significant risk of material adverse tax consequences to the Company or
the Person to whom such  Rights  Certificate  would be issued,  and (ii) no such
Rights  Certificate  shall be issued  if, and to the  extent  that,  appropriate
adjustment shall otherwise have been made in lieu of the issuance thereof.

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

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

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

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

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

               AeroCentury Corp.
               1440 Chapin Avenue
               Suite 310
               Burlingame, CA 94010
               Attention: President

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

               Continental Stock Transfer & Trust Company
               Two Broadway
               New York, NY  10004
               Attention:  Compliance 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
shares of Company Common Stock) shall be  sufficiently  given or made if sent by
first-class  mail,  postage prepaid,  addressed to such holder at the address of
such holder as shown on the registry books of the Company.

     Section 26. Supplements and Amendments.  Prior to the Distribution Date and
subject to the  penultimate  sentence  of this  Section  26, the Company and the
Rights Agent shall, if the Company so directs, supplement or amend any provision
of this  Agreement  in any  respect  without  the  approval  of any  holders  of
certificates  representing  shares of Company  Common Stock.  From and after the
Distribution  Date and subject to the  penultimate  sentence of this Section 26,
the Company and the Rights Agent shall, if the Company so directs, supplement or
amend this Agreement without the approval of any holders of Rights  Certificates
in order (i) to cure any ambiguity,  (ii) to correct or supplement any provision
contained  herein  which  may  be  defective  or  inconsistent  with  any  other
provisions  herein,  (iii) to shorten or lengthen any time period hereunder,  or
(iv) to change or supplement  the  provisions  hereunder in any manner which the
Company may deem necessary or desirable and which shall not adversely affect the
interests of the holders of Rights  Certificates (other than an Acquiring Person
or an Affiliate or Associate of an Acquiring Person);  provided,  however,  that
this  Agreement  may not be  supplemented  or amended to  lengthen,  pursuant to
clause (iii) of this sentence,  (A) subject to Section 30 hereof,  a time period
relating  to when the Rights may be  redeemed at such time as the Rights are not
then redeemable, or (B) any other time period unless such lengthening is for the
purpose of  protecting,  enhancing  or  clarifying  the  rights  of,  and/or the
benefits to, the holders of Rights.  Upon the delivery of a certificate  from an
appropriate  officer of the  Company  or, so long as any Person is an  Acquiring
Person hereunder,  from the majority of the Board of Directors which states that
the proposed  supplement  or amendment is in  compliance  with the terms of this
Section  26, the Rights  Agent  shall  execute  such  supplement  or  amendment.
Notwithstanding  anything  contained  in  this  Agreement  to the  contrary,  no
supplement  or  amendment  shall be made  without  the  approval of the Board of
Directors.  Prior to the  Distribution  Date,  the  interests  of the holders of
Rights shall be deemed  coincident  with the interests of the holders of Company
Common Stock.

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

     Section 28. Determinations and Actions by the Board of Directors,  etc. For
all  purposes  of this  Agreement,  any  calculation  of the number of shares of
Company Common Stock outstanding at any particular time,  including for purposes
of determining the particular  percentage of such outstanding  shares of Company
Common  Stock of which any  Person  is the  Beneficial  Owner,  shall be made in
accordance  with the last  sentence of Rule  13d-3(d)(1)(i)  of the Exchange Act
Regulations  as in effect on the date hereof.  Except as otherwise  specifically
provided herein,  the Board of Directors of the Company shall have the exclusive
power and authority to administer  this Agreement and to exercise all rights and
powers  specifically  granted  to  the  Board  or to the  Company,  or as may be
necessary or  advisable  in the  administration  of this  Agreement,  including,
without limitation,  the right and power (i) to interpret the provisions of this
Agreement, and (ii) to make all determinations deemed necessary or advisable for
the   administration  of  this  Agreement.   All  such  actions,   calculations,
interpretations and determinations (including, for purposes of clause (y) below,
all omissions with respect to the foregoing) which 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 or any member  thereof to any  liability to the holders of the
Rights.

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

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

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

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

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

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

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

     (c) In the event  that the number of shares of  Preferred  Stock or Company
Common Stock, as the case may be, which are authorized by the Company's Restated
Certificate of  Incorporation  but not  outstanding or reserved for issuance for
purposes other than upon exercise of the Rights are not sufficient to permit any
exchange  of Rights as  contemplated  in  accordance  with this  Section 34, the
Company,  upon a resolution of a majority of the Board of Directors,  shall take
all such action as may be necessary to authorize  additional shares of Preferred
Stock or Company Common Stock, as the case may be, for issuance upon exchange of
the Rights or make adequate  provision to  substitute,  in whole or in part, (1)
cash,  (2) other equity  securities of the Company,  (3) debt  securities of the
Company,  (4) other assets,  or (5) any combination of the foregoing,  having an
aggregate  value for each Right to be  exchanged  equal to the per share  market
price of one Unit of Preferred  Stock or share of Company  Common Stock,  as the
case may be  (determined  pursuant to Section  11(d) hereof) as of the date of a
Section  11(a)(ii)  Event,  where such aggregate  value has been determined by a
majority of the Board of Directors.

     (d) The  Company  shall  not be  required  to issue  fractions  of Units of
Preferred  Stock or fractions of shares of Company Common Stock or to distribute
certificates  which evidence  fractional Units or fractional  shares. In lieu of
issuing  fractional  Units or  fractional  shares,  the  Company  may pay to the
registered holders of Rights  Certificates at the time such Rights are exchanged
as herein  provided an amount in cash equal to the same  fraction of the current
market



price  (determined  pursuant  to  Section  11(d)  hereof)  of one  Unit  of
Preferred Stock or one share of Company Common Stock, as the case may be, on the
Trading Day immediately  prior to the date of exchange  pursuant to this Section
34.



     IN WITNESS  WHEREOF,  the parties  hereto have caused this  Agreement to be
duly executed, all as of the date first above written.
