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

         Effective  as of  September  3, 1996,  the Board of Directors of Accom,
Inc. (the  "Company")  declared a dividend of one preferred share purchase right
(a "Right") for each  outstanding  share of Common Stock,  $0.001 par value (the
"Common Shares"),  of the Company. The dividend is payable on September 24, 1996
(the  "Record  Date") to  stockholders  of record as of the close of business on
that date.  Each Right  entitles  the  registered  holder to  purchase  from the
Company one one-thousandth of a share of Series A Participating Preferred Stock,
$0.001  par  value,  of  the  Company  (the  "Preferred  Shares"),   subject  to
adjustment,  at a price of $20 per one-thousandth of a preferred share,  subject
to adjustment  (the "Purchase  Price").  The description and terms of the Rights
are set forth in a Preferred  Shares Rights  Agreement (the "Rights  Agreement")
dated as of  September  13, 1996  between the  Company and U.S.  Stock  Transfer
Corporation, as Rights Agent (the "Rights Agent").

         The  following  is a general  description  only and is  subject  to the
detailed  terms and  conditions  of the Rights  Agreement.  A copy of the Rights
Agreement,  including  the  Certificate  of  Designation,  the  form  of  Rights
Certificate  and the  Summary of Rights to be provided  to  stockholders  of the
Company,  is  attached  as  Exhibit  1 to  this  Registration  Statement  and is
incorporated herein by reference. 

Rights Evidenced by Common Share Certificates

         The Rights will not be exercisable until the Distribution Date (defined
below).  Accordingly,  Common Share certificates  outstanding on the Record Date
will evidence the Rights related thereto,  and Common Share certificates  issued
after the Record Date will contain a notation incorporating the Rights Agreement
by reference.  Until the Distribution Date (or earlier  redemption,  exchange or
expiration  of the Rights),  the surrender or transfer of any  certificates  for
Common  Shares,  even without  notation or a copy of the Summary of Rights being
attached  thereto,  will also  constitute the transfer of the Rights  associated
with the Common Shares represented by such certificate.

                                      -2-
<PAGE>

Distribution Date

         The Rights will separate from the Common Shares,  certificates  for the
rights  ("Rights  Certificates")  will be  issued  and the  Rights  will  become
exercisable  upon the earlier of: (i) the close of business on the tenth day (or
such later date as may be  determined  by a majority of the Board of  Directors,
excluding directors  affiliated with the Acquiring Person, as defined below (the
"Continuing  Directors")) following a public announcement that a person or group
of  affiliated  or  associated  persons has  acquired,  or obtained the right to
acquire,  beneficial  ownership of 15% or more of the outstanding  Common Shares
(an "Acquiring  Person") or (ii) the close of business on the tenth day (or such
later date as may be  determined  by a  majority  of the  Continuing  Directors)
following the commencement of a tender offer or exchange offer, the consummation
of which would result in the beneficial ownership by a person or group of 15% or
more of the outstanding  Common Shares. The earlier of such dates is referred to
as the  "Distribution  Date".  

Issuance of Rights Certificates, Expiration of Rights

         As soon as practicable following the Distribution Date, separate Rights
Certificates  will be mailed to holders of record of the Common Shares as of the
close of business on the Distribution Date and such separate Rights Certificates
alone will  evidence  the Rights from and after the  Distribution  Date.  Unless
otherwise  determined by the Board of Directors,  all Common Shares issued prior
to the Distribution Date will be issued with Rights.  Common Shares issued after
the  Distribution  Date may be issued  with Rights if such shares are issued (i)
upon the exercise, conversion or exchange of securities issued after adoption of
the Rights  Agreement or (ii) pursuant to the exercise of stock options or under
any employee benefit plan or arrangement.  Except as otherwise determined by the
Board of Directors,  no other Common Shares issued after the  Distribution  Date
will be issued with  Rights.  In  addition,  no Common  Shares  issued after the
Distribution  Date will be issued with Rights if such  issuance  would result in
(or create a significant  risk) (i) of material  adverse tax consequences to the
Company or the person to whom such  Rights  Certificate  would be issued or (ii)
that such options or plans would not qualify for otherwise available special tax
treatment.  The Rights will expire on September  3, 2006 (the 



                                      -3-
<PAGE>

"Final Expiration Date"), unless the Final Expiration Date is extended or unless
the Rights are  earlier  redeemed  or  exchanged  by the  Company or expire upon
consummation of certain mergers, consolidations or sales of assets, as described
below.

Initial Exercise of the Rights

         Following the Distribution Date, and until the occurrence of one of the
subsequent  events  described  below,  holders of the Rights will be entitled to
receive,  upon exercise and the payment of $20 (the "Purchase Price") per Right,
one one-thousandth of a Preferred Share.

Exchange Provision

         At any time after an Acquiring  Person has become such and prior to the
Acquiring  Person  beneficially  owning  50% or more of the  outstanding  Common
Shares,  the Board of Directors  of the Company may  exchange the Rights  (other
than Rights owned by the  Acquiring  Person or its  affiliates),  in whole or in
part,  at  an  exchange  ratio  of  one  Common  Share  per  Right  (subject  to
adjustment). 

Right to Buy Common Shares at Half Price

         Unless the Rights are earlier redeemed or exchanged,  in the event that
an Acquiring Person becomes such, other than pursuant to a tender offer which is
made for all of the outstanding  Common Shares and approved by a majority of the
Continuing  Directors  after  determining  that the offer is both  adequate  and
otherwise  in the  best  interests  of  the  Company  and  its  stockholders  (a
"Permitted Offer"),  then proper provision will be made so that each holder of a
Right which has not theretofore been exercised  (other than Rights  beneficially
owned by the Acquiring  Person,  which will  thereafter be void) will thereafter
have the right to receive,  upon exercise of a Right,  a number of Common Shares
having a then current value equal to two times the Purchase  Price. In the event
that the Company does not have a sufficient  number of Common Shares  available,
or the Board  decides  that such  action is  necessary  or  appropriate  and not
contrary  to the  interests  of Rights  holders,  the Company  may,  among other
things,  instead  substitute  cash,  assets or other  securities  for the Common
Shares into which the Rights would have otherwise been exercisable. 



                                      -4-
<PAGE>

Right to Buy Acquiring Company Stock at Half Price

         Similarly,  unless the Rights are earlier redeemed or exchanged, in the
event  that,  after the Shares  Acquisition  Date (as  defined  below),  (i) the
Company  consolidates  with or merges into another  entity,  (ii) another entity
consolidates  with or merges  into the  Company  or (iii) the  Company  sells or
otherwise  transfers 50% or more of its  consolidated  assets or earning  power,
proper  provision  must be made so that  each  holder  of a Right  which has not
theretofore  been  exercised  (other  than  Rights  beneficially  owned  by  the
Acquiring Person,  which will thereafter be void) will thereafter have the right
to receive,  upon exercise,  a number of shares of common stock of the acquiring
company  having a then  current  value  equal to two  times the  Purchase  Price
(unless the transaction  satisfies certain  conditions and is consummated with a
person who  acquired  shares  pursuant to a Permitted  Offer,  in which case the
Rights will expire). 

Adjustments to Prevent Dilution

         The  Purchase  Price  payable,  the  number of Rights and the number of
Preferred  Shares,  Common Shares or other securities or property  issuable upon
exercise  of the Rights are subject to  adjustment  from time to time to prevent
dilution  as set forth in the Rights  Agreement.  With  certain  exceptions,  no
adjustment in the Purchase Price will be required until  cumulative  adjustments
require an adjustment of at least 1% in such Purchase Price.

Rights and Preferences of the Preferred Shares

         Preferred  Shares  purchasable  upon exercise of the Rights will not be
redeemable.  Each Preferred  Share will be entitled to an aggregate  dividend of
1,000 times the dividend declared per Common Share. In the event of liquidation,
the  holders  of  the  Preferred  Shares  will  be  entitled  to a  preferential
liquidation  payment equal to accrued but unpaid  dividends  plus the greater of
$1,000 per share or 1,000 times the aggregate per share amount to be distributed
to the holders of Common  Shares.  Each  Preferred  Share will have 1,000 votes,
voting together with the holders of Common Shares,  except as required by law or
the Certificate of Determination of Rights, Preferences and Privileges of Series
A Participating  Preferred  Stock. In the event of any merger,  


                                      -5-
<PAGE>

consolidation  or other  transaction  in which  Common  Shares  are  changed  or
exchanged,  each  Preferred  Share will be entitled  to receive  1,000 times the
amount  received  per Common  Share.  These  rights are  protected  by customary
anti-dilution provisions. Because of the nature of the dividend, liquidation and
voting  rights of the  Preferred  Shares,  the  value of the one  one-thousandth
interest in a Preferred  Share  purchasable  upon  exercise of each Right should
approximate the value of one Common Share.

Redemption

         At any time prior to the close of  business  on the  earlier of (i) the
tenth  day  following  the  date  (the  "Shares  Acquisition  Date")  of  public
announcement  that an Acquiring Person has become such or such later date as may
be determined by a majority of the Continuing  Directors and publicly  announced
by the Company or (ii) the Final Expiration Date of the Rights,  the Company may
redeem  the  Rights  in  whole,  but not in part,  at a price of $0.01 per Right
("Redemption Price"). 

No Stockholders' Rights Prior to Exercise

         Until a Right is exercised,  the holder thereof,  as such, will have no
rights as a stockholder  of the Company  (other than any rights  resulting  from
such holder's ownership of Common Shares),  including,  without limitation,  the
right to vote or to receive dividends. 

Amendment of Rights Agreement

         The provisions of the Rights  Agreement may be  supplemented or amended
by the Board of Directors in any manner prior to the  Distribution  Date without
the approval of Rights holders.  After the Distribution  Date, the provisions of
the Rights Agreement may be supplemented or amended by the Board in order to (i)
cure any  ambiguity,  defect or  inconsistency,  (ii) to make changes  which are
deemed  necessary  or advisable  and do not  adversely  affect the  interests of
holders of Rights (excluding the interests of any Acquiring Person), or (iii) to
shorten  or  lengthen  any time  period  under the Rights  Agreement;  provided,
however,  that no amendment to lengthen (A) the time period governing redemption
shall be made at such time as the  Rights are not  



                                      -6-
<PAGE>

redeemable,  or (B) any other  period  unless  for the  purpose  of  protecting,
enhancing  or  clarifying  the rights of,  and/or  benefits  to, the  holders of
Rights.

Certain Anti-takeover Effects

         The Rights  approved by the Board are  designed to protect and maximize
the value of the outstanding  equity interests in the Company in the event of an
unsolicited  attempt by an acquiror to take over the Company,  in a manner or on
terms not  approved  by the Board of  Directors.  Takeover  attempts  frequently
include coercive  tactics to deprive a corporation's  Board of Directors and its
stockholders   of  any  real   opportunity  to  determine  the  destiny  of  the
corporation.  The Rights have been  declared by the Board in order to deter such
tactics,  including a gradual accumulation of shares in the open market of a 15%
or greater  position to be followed by a merger or a partial or two-tier  tender
offer  that does not treat all  stockholders  equally.  These  tactics  unfairly
pressure stockholders,  squeeze them out of their investment without giving them
any real choice and deprive them of the full value of their shares.

         The Rights are not  intended  to prevent a takeover  of the Company and
will not do so.  The  Rights  are not  exercisable  in the event of a  Permitted
Offer,  as described  above.  The Rights may be redeemed by the Company at $0.01
per Right within ten days (or such later date as may be determined by a majority
of the  Continuing  Directors)  after  the  accumulation  of 15% or  more of the
Company's outstanding Common Shares by a single acquiror or group.  Accordingly,
the Rights  should not preclude any merger or business  combination  approved by
the Board of  Directors.  Issuance  of the Rights does not in any way weaken the
financial  strength of the Company or  interfere  with its business  plans.  The
issuance  of the  Rights  has no  immediate  dilutive  effect,  will not  affect
reported  earnings  per share,  should  not be taxable to the  Company or to its
stockholders  and will not  change  the way in which the  Company's  shares  are
presently  traded.  The  Company's  Board of Directors  believes that the Rights
represent a sound and  reasonable  means of  addressing  the  complex  issues of
corporate  policy  created by the current  takeover  environment.  However,  the
Rights  may have the effect of  rendering  more  difficult  or  discouraging  an
acquisition  of the Company deemed  undesirable  by the Board of Directors.  The


                                      -7-
<PAGE>

Rights may cause  substantial  dilution  to a person or group that  attempts  to
acquire the Company on terms or in a manner not approved by the Company's  Board
of  Directors,  except  pursuant  to an offer  conditioned  upon  the  negation,
purchase or redemption of the Rights.

                        PREFERRED SHARES RIGHTS AGREEMENT


         This Agreement is dated as of September 13, 1996, by and between Accom,
Inc.,  a Delaware  corporation  (the  "Company"),  and the U.S.  Stock  Transfer
Corporation, a California banking corporation (the "Rights Agent").

         Effective as of September  3, 1996 (the  "Rights  Dividend  Declaration
Date"), the Board of Directors of the Company authorized and declared a dividend
of one  Preferred  Share  purchase  right (a "Right")  for each Common Share (as
hereinafter  defined) of the Company outstanding as of the Close of Business (as
hereinafter  defined) on  September  24, 1996 (the  "Record  Date").  Each Right
represents  the right to  purchase  one  one-thousandth  (1/1000)  of a share of
Series A Participating  Preferred Stock (as such number may be adjusted pursuant
to the  provisions  of this  Agreement),  having  the  rights,  preferences  and
privileges  set  forth in the form of  Certificate  of  Designation  of  Rights,
Preferences  and Privileges of Series A  Participating  Preferred Stock attached
hereto as Exhibit A, subject to the terms and subject to the  conditions  herein
set forth. The Board of Directors of the Company further authorized and directed
the  issuance  of one Right (as such  number  may be  adjusted  pursuant  to the
provisions  of this  Agreement)  with  respect to each  Common  Share that shall
become  outstanding  between the Record Date and the earlier of the Distribution
Date and the Expiration  Date (as such terms are  hereinafter  defined),  and in
certain circumstances after the Distribution Date.

         NOW,  THEREFORE,  in  consideration  of the  promises  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  and  Associates  of such  Person,  shall be the
Beneficial Owner of 15% or more of the Common Shares then outstanding, but shall
not include the Company,  any Subsidiary of the Company or any employee  benefit
plan of the Company or of any  Subsidiary of the Company,  or any entity holding
Common Shares for or pursuant to the terms of any such plan. Notwithstanding the
foregoing,  no  Person  shall be deemed to be an  Acquiring  Person:  (i) as the
result of an acquisition of Common Shares by the Company which,  by reducing the
number of  shares  outstanding,  increases  the  proportionate  number of shares
beneficially  owned by such  Person to 15% or more of the  Common  Shares of the
Company then outstanding;  provided,  however, that if a Person shall become the
Beneficial  Owner  of 15% or more  of the  Common  Shares  of the  Company  then
outstanding  by reason of share  purchases by the Company and shall,  after such
share  purchases by the Company,  become the Beneficial  Owner of any additional
Common  Shares  of the  Company,  then  such  Person  shall be  deemed  to be an
Acquiring  Person,  , or (ii) if within  eight  days  after  such  Person  would
otherwise  become an  Acquiring  Person  (but for the  operation  of this clause
(ii)),  such  Person  notifies  the Board of  Directors  that such Person did so
inadvertently  and within two days after such  notification,  such Person is the
Beneficial Owner of less than 15% of the outstanding Common Shares. In addition,
neither El Dorado  Ventures nor Junaid Sheikh shall be deemed to be an Acquiring
Person so long as such Person,  together with all  


<PAGE>

Affiliates and Associates of such Person,  shall be the Beneficial  Owner of 30%
or less of the Common  Shares  then  outstanding  (including  all Common  Shares
beneficially owned by such Person as of September 3, 1996).

                  (b)  "Affiliate"  and  "Associate"  shall have the  respective
meanings  ascribed  to such  terms  in  Rule  12b-2  of the  General  Rules  and

comparable or successor law or regulation);

                           (ii)  which  such  Person  or  any of  such  Person's
Affiliates  or  Associates  has (A) the right to acquire  (whether such right is
exercisable  immediately  or only  after the  passage of time)  pursuant  to any
agreement,  arrangement or understanding  (other than customary  agreements with
and between  underwriters  and selling group members with respect to a bona fide
public  offering of  securities),  or upon the  exercise of  conversion  rights,
exchange  rights,  rights  (other than the  Rights),  warrants  or  options,  or
otherwise; provided, however, that a Person shall not be deemed pursuant to this
Section  l(c)(ii)(A)  the  Beneficial  Owner of,  or to  beneficially  own,  (1)
securities  tendered pursuant to a tender or exchange offer made by or on behalf
of such  Person or any of such  Person's  Affiliates  or  Associates  until such
tendered  securities  are accepted for purchase or exchange,  or (2)  securities
which a Person or any of such Person's Affiliates or Associates may be deemed to
have the right to acquire pursuant to any merger or other acquisition  agreement
between  the  Company  and  such  Person  (or one or more of its  Affiliates  or
Associates) if such agreement has been approved by the Board of Directors of the
Company  prior to there  being an  Acquiring  Person;  or (B) the  right to vote
pursuant to any agreement, arrangement or understanding; provided, however, that
a Person shall not be deemed the Beneficial  Owner of, or to  beneficially  own,
any security under this Section  l(c)(ii)(B)  if the  agreement,  arrangement or
understanding  to vote such security (1) arises solely from a revocable proxy or

solicitation  made pursuant to, and in accordance with, the applicable rules and
regulations of the Exchange Act and (2) is not also then  reportable on Schedule

customary  agreements  with and between  underwriters  and selling group members
with respect to a bona fide public  offering of  securities)  for the purpose of
acquiring,  holding, voting (except to the extent contemplated by the proviso to
Section  l(c)(ii)(B))  or disposing of any securities of the Company;  provided,
however,  that in no case shall an officer or  director of the Company be deemed
(x) the Beneficial Owner of any securities beneficially owned by another officer
or  director  of the  Company  solely by reason of  actions  undertaken  by such


                                      -2-

         Section 3.        Issuance of Rights Certificate.

                  (a)  Until  the  Distribution  Date,  (i) the  Rights  will be
evidenced  (subject to the  provisions  of Sections 3(b) and 3(c) hereof) by the
certificates  for Common Shares  registered in the names of the holders  thereof
(which  certificates shall also be deemed to be Rights  Certificates) and not by

Until the earlier of the Distribution Date or the Expiration Date, the surrender
for transfer of such  certificates  for Common Shares shall also  constitute the

represented  thereby.  As soon as practicable  after the Distribution  Date, the

Date,  at the address of such  holder  shown on the  records of the  Company,  a
Rights  Certificate,  in  substantially  the form of Exhibit B hereto (a "Rights
Certificate"),  evidencing  one Right for each Common Share so held,  subject to
adjustment as 



                                      -5-
<PAGE>

provided  herein.  In the event that an  adjustment  in the number of Rights per
Common  Share has been made  pursuant  to  Section  11(a)(i),  Section  11(i) or
Section  11(p)  hereof,   then  at  the  time  of  distribution  of  the  Rights
Certificates,  the Company  shall make the necessary  and  appropriate  rounding
adjustments   (in   accordance   with  Section  14(a)  hereof)  so  that  Rights
Certificates  representing only whole numbers of Rights are distributed and cash
is paid in lieu of any  fractional  Rights.  As of the  Distribution  Date,  the
Rights  will  be  evidenced  solely  by  such  Rights  Certificates  and  may be
transferred  by the transfer of the Rights  Certificates  as  permitted  hereby,
separately  and apart from any  transfer of one or more Common  Shares,  and the
holders of such Rights  Certificates  as listed in the records of the Company or
any  transfer  agent or  registrar  for the Rights  shall be the record  holders
thereof.

                  (b) On the Record Date or as soon as  practicable  thereafter,
the Company will send a copy of a Summary of Rights in substantially the form of
Exhibit C hereto (the  "Summary of  Rights"),  by  first-class,  postage-prepaid
mail,  to each record holder of Common Shares as of the close of business on the
Record Date, at the address of such holder shown on the records of the Company.

                  (c) Unless the Board of Directors by resolution  adopted at or
before the time of the  issuance  (including  pursuant to the exercise of rights
under  the  Company's  benefit  plans) of any  Common  Shares  specifies  to the
contrary, Rights shall be issued in respect of all Common Shares that are issued
after the Record Date but prior to the earlier of the  Distribution  Date or the
Expiration  Date or, in  certain  circumstances  provided  in Section 22 hereof,
after the Distribution Date. Certificates  representing such Common Shares shall
also be deemed to be  certificates  for  Rights,  and shall  bear the  following
legend:

         This  certificate  also  evidences  and entitles  the holder  hereof to
         certain  rights as set forth in a  Preferred  Shares  Rights  Agreement
         between  Accom,  Inc. and the U.S.  Stock  Transfer  Corporation as the
         Rights Agent, dated as of September 13, 1996 (the "Rights  Agreement"),
         the terms of which are hereby  incorporated  herein by reference  and a
         copy of which is on file at the principal  executive  offices of Accom,
         Inc. Under certain circumstances, as set forth in the Rights Agreement,
         such Rights will be  evidenced  by  separate  certificates  and will no
         longer be evidenced by this  certificate.  Accom, Inc. will mail to the
         holder  of this  certificate  a copy of the  Rights  Agreement  without
         charge  after  receipt of a written  request  therefor.  Under  certain
         circumstances set forth in the Rights  Agreement,  Rights issued to, or
         held by, any Person who is, was or becomes an  Acquiring  Person or any
         Affiliate or Associate thereof (as such terms are defined in the Rights
         Agreement), whether currently held by or on behalf of such Person or by
         any subsequent holder, may become null and void.

With respect to such  certificates  containing the foregoing  legend,  until the
earlier of (i) the  Distribution  Date or (ii) the  Expiration  Date, the Rights
associated  with the Common Shares  represented  by such  certificates  shall be
evidenced by such certificates alone, and the surrender for transfer of any such
certificate shall also constitute the transfer of the Rights associated with the
Common Shares  represented  thereby.  In the event that the Company purchases or
acquires any Common  Shares after the Record Date but prior to the  Distribution
Date, any Rights associated with such Common Shares shall be deemed canceled and
retired  so that the  Company  shall not be  



                                      -6-
<PAGE>

entitled to exercise any Rights  associated  with the Common Shares which are no
longer outstanding.

         Section 4.        Form of Rights Certificate.

                  (a) The  Rights  Certificates  (and the forms of  election  to
purchase  Common Shares and of assignment to be printed on the reverse  thereof)
shall be  substantially  in the form of Exhibit B hereto and may have such marks
of  identification  or designation  and such legends,  summaries or endorsements
printed thereon as the Company may deem  appropriate and as are not inconsistent
with the provisions of this Agreement,  or as may be required to comply with any
applicable law or with any rule or regulation made pursuant  thereto or with any
rule or  regulation  of any stock  exchange on which the Rights may from time to
time be listed, or to conform to usage.  Subject to the provisions of Section 11
and Section 22 hereof, the Rights Certificates,  whenever distributed,  shall be
dated as of the Record  Date (or in the case of Rights  issued  with  respect to
Common  Shares  issued by the Company  after the Record Date,  as of the date of
issuance of such Common Shares), shall show the date of countersignature, and on
their  face  shall  entitle  the  holders  thereof to  purchase  such  number of
one-thousandths  of a Preferred Share as shall be set forth therein at the price
set forth therein (such  exercise  price per one  one-thousandth  of a Preferred
Share being  hereinafter  referred to as the "Purchase  Price" and the aggregate
exercise price of all Preferred Shares issuable upon exercise of one Right being
hereinafter  referred to as the "Total Exercise Price"), but the number and type
of securities purchasable upon the exercise of each Right and the Purchase Price
shall be subject to adjustment as provided herein.

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

         The  Rights   represented  by  this  Rights  Certificate  are  or  were
         beneficially owned by a Person who was or became an Acquiring Person or
         an Affiliate  or  Associate  of an Acquiring  Person (as such terms are
         defined in the Rights Agreement).  Accordingly, this Rights Certificate
         and the  Rights  represented  hereby  may  become  null and void in the
         circumstances specified in Section 7(e) of the Rights Agreement.

In the event  that the  Rights  become  exercisable,  the  Rights  Agent and the
Company  will agree upon a procedure  for  determining  which  Rights will be so
legended.

         Section 5.        Countersignature and Registration.

                  (a) The Rights Certificates shall be executed on behalf of the
Company by its Chairman of the Board, its Chief Executive Officer, its President
or any Vice  President,  either manually or by facsimile  signature,  and by the
Secretary  or an  Assistant  Secretary  of the  Company,  either  manually or by
facsimile signature,  and shall have affixed thereto the Company's seal (if any)
or a facsimile thereof. The Rights Certificates shall be manually  countersigned
by an  authorized  signatory  of the Rights Agent and shall not be valid for any
purpose unless countersigned.  In case any officer of the Company who shall have
signed  any of the Rights  Certificates  shall  cease to be such  officer of the
Company before countersignature by the Rights Agent and issuance and delivery by
the Company, such Rights Certificates, nevertheless, may be countersigned by the
Rights  Agent and issued and  delivered  by the Company  with the same force and
effect as though the person who signed such Rights  Certificates  had not ceased
to be such officer of the Company;  and any Rights  Certificate may be signed on
behalf of the Company by any person who, at the actual date of the  execution of
such Rights  Certificate,  shall be a proper officer of the Company to sign such
Rights  Certificate,  although  at the  date of the  execution  of  this  Rights
Agreement any such person was not such an officer.

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

         Section 6.  Transfer,  Split Up,  Combination  and  Exchange  of Rights
Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates.

                  (a)  Subject to the  provisions  of Sections  7(e),  14 and 24
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 Rights  Certificates may be transferred,  split up, combined or exchanged for
another  Rights  Certificate  or Rights  Certificates,  entitling the registered
holder to purchase a like number of  one-thousandths  of a Preferred  Share (or,
following a Triggering  Event,  other  securities,  cash or other assets, as the
case may be) as the Rights Certificate or Rights  Certificates  surrendered then
entitled such holder to purchase.  Any registered  holder  desiring to transfer,
split up,  combine or exchange  any Rights  Certificate  or Rights  Certificates
shall make such  request in writing  delivered  to the Rights  Agent,  and shall
surrender the Rights Certificate or Rights Certificates to be transferred, split
up, combined or exchanged at the 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 signed the
certificate  contained  in the form of  assignment  on the reverse  side of such
Rights  Certificate  and shall have  provided  such  additional  evidence of the
identity of the Beneficial Owner (or former  Beneficial  Owner) or Affiliates or
Associates thereof as the Company shall reasonably request. Thereupon the Rights
Agent shall, subject to Sections 7(e), 14 and 24 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  


                                      -8-
<PAGE>

governmental  charge that may be imposed in connection with any transfer,  split
up, combination or exchange of Rights Certificates.

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

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

                  (a) Subject to Section 7(e) hereof,  the registered  holder of
any Rights  Certificate  may exercise the Rights  evidenced  thereby  (except as
otherwise  provided  herein)  in  whole  or  in  part  at  any  time  after  the
Distribution  Date upon  surrender of the Rights  Certificate,  with the form of
election to purchase on the reverse side thereof  duly  executed,  to the Rights
Agent at the office of the Rights Agent  designated  for such purpose,  together
with payment of the Purchase Price for each  one-thousandth of a Preferred Share
as to which the Rights are exercised, at or prior to the Expiration Date.

                  (b) The Purchase Price for each  one-thousandth of a Preferred
Share  issuable  pursuant to the exercise of a Right shall  initially be $20 and
shall be subject to adjustment  from time to time as provided in Sections 11 and
13 hereof and shall be payable in lawful  money of the United  States of America
in accordance with paragraph (c) below.

                  (c)  Upon  receipt  of  a  Rights   Certificate   representing
exercisable  Rights,  with the  form of  election  to  purchase  duly  executed,
accompanied by payment of the Purchase  Price for the number of  one-thousandths
of a Preferred Share (or other securities or property, as the case may be) to be
purchased and an amount equal to any applicable transfer tax required to be paid
by the holder of such Rights  Certificate in accordance with Section 9 hereof in
cash,  or by  certified  check or  cashier's  check  payable to the order of the
Company,  the Rights Agent shall,  subject to Section  20(k)  hereof,  thereupon
promptly (i) (A) requisition from any transfer agent of the Preferred Shares (or
make  available,  if the Rights  Agent is the transfer  agent for the  Preferred
Shares) a certificate or  certificates  for the number of  one-thousandths  of a
Preferred  Share to be purchased and the Company hereby  irrevocably  authorizes
its transfer  agent to comply with all such requests or (B) if the Company shall
have elected to deposit the total number of one-thousandths of a Preferred Share
issuable  upon  exercise  of  the  Rights  hereunder  with a  depository  agent,
requisition from the depository agent of depository  receipts  representing such
number of  one-thousandths of a Preferred Share as are to be purchased (in which
case certificates for the Preferred Shares represented by such receipts shall be
deposited  by the  transfer  agent with the  depository  agent) and the  Company
hereby  directs  the  depository  agent to comply with such  request,  (ii) when
appropriate,  requisition from the Company the amount of cash to be paid in lieu
of issuance of  fractional  shares in accordance  with Section 14 hereof,  (iii)
after receipt of such certificates or depository receipts,  cause the same to be
delivered  to or  upon  the  order  of the  



                                      -9-
<PAGE>

registered holder of such Rights  Certificate,  registered in such name or names
as may be  designated  by such holder and (iv) when  appropriate,  after receipt
thereof, deliver such cash to or upon the order of the registered holder of such
Rights  Certificate.  The payment of the  Purchase  Price (as such amount may be
reduced (including to zero) pursuant to Section 11(a)(iv) hereof) may be made in
cash or by  certified  check or  cashier's  check  payable  to the  order of the
Company. In the event that the Company is obligated to issue 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 other
securities,  cash and/or other  property are available for  distribution  by the
Rights Agent, if and when appropriate.

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

                  (e)   Notwithstanding   anything  in  this  Agreement  to  the
contrary, from and after the first occurrence of a Triggering Event or a Section
13  Event,  any  Rights  beneficially  owned by (i) an  Acquiring  Person  or an
Associate or Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring
Person (or of any such  Associate or Affiliate)  who becomes a transferee  after
the Acquiring Person becomes such (a "Post  Transferee"),  (iii) a transferee of
an  Acquiring  Person (or of any such  Associate  or  Affiliate)  who  becomes a
transferee prior to or concurrently  with the Acquiring Person becoming such and
receives  such  Rights  pursuant  to either (A) a transfer  (whether  or not for
consideration)  from the Acquiring Person to holders of equity interests in such
Acquiring  Person  or to any  Person  with  whom the  Acquiring  Person  has any
continuing  agreement,  arrangement or  understanding  regarding the transferred
Rights or (B) a  transfer  which  the  Board of  Directors  of the  Company  has
determined  is part of a  plan,  arrangement  or  understanding  which  has as a
primary  purpose  or  effect  the  avoidance  of this  Section  7(e)  (a  "Prior
Transferee") or (iv) any subsequent transferee receiving transferred Rights from
a Post Transferee or a Prior Transferee,  either directly or through one or more
intermediate transferees,  shall become null and void without any further action
and no holder of such Rights  shall have any rights  whatsoever  with respect to
such Rights,  whether  under any provision of this  Agreement or otherwise.  The
Company shall use all  reasonable  efforts to insure that the provisions of this
Section  7(e) and  Section  4(b)  hereof are  complied  with,  but shall have no
liability  to any  holder of  Rights  Certificates  or to any other  Person as a
result of its failure to make any  determinations  with  respect to an Acquiring
Person or any of such Acquiring Person's  Affiliates,  Associates or transferees
hereunder.

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


                                      -10-
<PAGE>

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

         Section 9. Reservation and Availability of Preferred Share.

                  (a) The Company covenants and agrees that it will use its best
efforts to cause to be reserved and kept  available  out of and to the extent of
its authorized and unissued  shares of Preferred  Stock not reserved for another
purpose  (and,  following  the  occurrence  of a  Triggering  Event,  out of its
authorized  and unissued  shares of Common Stock and/or other  securities),  the
number of Preferred  Shares (and,  following the  occurrence  of the  Triggering
Event,  Common Stock and/or other  securities) that will be sufficient to permit
the exercise in full of all outstanding Rights.

                  (b) If the Company shall  hereafter  list any of its Preferred
Shares on a national securities  exchange,  then so long as the Preferred Shares
(and, following the occurrence of a Triggering Event, Common Shares and/or other
securities)  issuable and deliverable  upon exercise of the Rights may be listed
on a national  securities  exchange,  the Company  shall use its best efforts to
cause,  from and after such time as the Rights become  exercisable  (but only to
the extent that it is reasonably likely that the Rights will be exercised),  all
shares  reserved for such  issuance to be listed on such  exchange upon official
notice of issuance upon such exercise.

                  (c) The  Company  shall use its best  efforts to (i) file,  as
soon as practicable  following the earliest date after the first occurrence of a
Triggering Event in which the  consideration to be delivered by the Company upon
exercise of the Rights has been determined in accordance with Section  11(a)(iv)
hereof, or as soon as is required by law following the Distribution Date, as the
case may be, a  registration  statement  under the  Securities  Act of 1933,  as
amended (the "Securities Act"), with respect to the securities  purchasable upon
exercise  of the Rights on an  appropriate  form,  (ii) cause such  registration
statement to become effective as soon as practicable after such filing and (iii)
cause such registration  statement to remain effective (with a prospectus at all
times meeting the  requirements  of the Securities Act) until the earlier of (A)
the date as of which the Rights are no longer  exercisable  for such  securities
and (B) the date of  expiration  of the  Rights.  The  Company  may  temporarily
suspend, for a period not to exceed ninety (90) 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,  and notify the Rights Agent, that the  exercisability of
the Rights has been temporarily suspended,  as well as a public announcement and
notification  to the Rights Agent at such time as the suspension



                                      -11-
<PAGE>

is no longer  in  effect.  The  Company  will  also  take such  action as may be
appropriate  under, or to ensure  compliance  with, the securities or "blue sky"
laws of the various states in connection with the  exercisability of the Rights.
Notwithstanding  any  provision of this  Agreement to the  contrary,  the Rights
shall not be exercisable in any jurisdiction, unless the requisite qualification
in such jurisdiction shall have been obtained,  or an exemption  therefrom shall
be available,  and until a registration  statement has been declared  effective.
The Company  will  notify the Rights  Agent in writing of the  jurisdictions  in
which Rights shall not be exercisable pursuant to the preceding sentence.

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

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

         Section 10. Preferred Shares Record Date. Each person in whose name any
certificate for a number of  one-thousandths of a Preferred Share is issued upon
the  exercise  of Rights  shall for all  purposes  be deemed to have  become the
holder  of  record  of  Preferred  Shares  represented   thereby  on,  and  such
certificate  shall  be  dated,  the  date  upon  which  the  Rights  Certificate
evidencing  such Rights was duly  surrendered  and payment of the Purchase Price
multiplied by the number of one-thousandths of a Preferred Share with respect to
which the Rights have been  exercised (and any  applicable  transfer  taxes) was
made;  provided,  however,  that if the date of such  surrender and payment is a
date upon which the Preferred  Shares  transfer books of the Company are closed,
such person shall be deemed to have become the record  holder of such shares on,
and such certificate  shall be dated, the next succeeding  Business Day on which
the  Preferred  Shares  transfer  books of the  Company  are open.  Prior to the
exercise of the Rights  evidenced  thereby,  the holder of a Rights  Certificate
shall not be  entitled to any rights of a holder of  Preferred  Shares for which
the Rights shall be exercisable,  including,  without  limitation,  the 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 of Shares or Number of
Right.  The  Purchase  Price,  the number  and kind of shares or other  property
covered  by each  Right and the  number of Rights  outstanding  are  subject  to
adjustment from time to time as provided in this Section 11.


                                      -12-

                  (a) (i) In the event the  Company  shall at any time after the
date of this  Agreement (A) declare a dividend on the Common  Shares  payable in
Common Shares,  (B) subdivide the  outstanding  Common  Shares,  (C) combine the
outstanding  Common Shares (by reverse stock split or otherwise)  into a smaller
number of Common  Shares,  or (D) issue  any  shares of its  capital  stock in a
reclassification  of the Common Shares (including any such  reclassification  in
connection with a consolidation or merger in which the Company is the continuing
or  surviving  corporation),  then,  in each such  event,  except  as  otherwise
provided in this Section  11(a) and Section 7(e) hereof:  (1) each of the Rights
outstanding  at the time of the record date for such  dividend or the  effective
date  of  such   subdivision,   combination   or   reclassification   shall   be
proportionately adjusted to that number of Rights (calculated to the nearest one
ten-thousandth  (1/10,000)  of a  Right)  equal  to a  fraction  (the  "Exchange
Ratio"),  the  numerator of which shall be the total number of Common  Shares or
shares of capital  stock issued in such  reclassification  of the Common  Shares
outstanding  immediately  following such time and the denominator of which shall
be the total number of Common Shares outstanding immediately prior to such time,
and the number of Rights that shall  thereafter  be issued with  respect to each
Common Share or share of such other capital stock that shall become  outstanding
thereafter prior to the Distribution  Date shall be equal to the total number of
outstanding  Rights  immediately  after such event (as adjusted pursuant to this
clause (1)) divided by the total number of  outstanding  Common Shares or shares
of such other capital  stock  immediately  after such event  (subject to further
adjustment pursuant to the provisions of this Agreement); (2) 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  shall be adjusted so
that the Purchase Price  thereafter  shall equal the result obtained by dividing
the  Purchase  Price in effect  immediately  prior to such time by the  Exchange
Ratio;  provided,  however,  that in no event shall the consideration to be paid
upon the  exercise  of one  Right be less  than the  aggregate  par value of the
shares of capital stock of the Company issuable upon exercise of such Right; and
(3) the  number  of  Preferred  Shares or shares  of such  other  capital  stock
issuable  upon the  exercise of each Right shall  remain  unchanged  immediately
after such event,  but, in the event of a  reclassification,  the kind of shares
issuable upon the exercise of each Right immediately after such reclassification
shall be adjusted to be the kind of shares of such other capital stock issued in
such  reclassification,  rather than Preferred  Shares. 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) Subject to Section 24 of this Agreement, in the event
a Triggering Event shall have occurred,  then promptly following such Triggering
Event,  proper provision shall be made so that each holder of a Right, except as
provided in Section 7(e) hereof,  shall thereafter have the right to receive for
each Right, upon exercise thereof in accordance with the terms of this Agreement
and payment of the  then-current  Total Exercise  Price,  in lieu of a number of
one-thousandths  of a  Preferred  Share,  such  number of  Common  Shares of the
Company as shall  equal the result  obtained  by  multiplying  the  then-current
Purchase Price by the then number of  one-thousandths  of a Preferred  Share for
which  a  Right  was  exercisable  (or  would  have  been   exercisable  if  the
Distribution  Date had occurred)  immediately prior to the first occurrence of a
Triggering  Event,  and  dividing  that  product by 50% of the current per share
market price (determined  pursuant to Section 11(d) hereof) for Common Shares on
the date of  occurrence  of 



                                      -13-
<PAGE>

the Triggering Event (such number of shares being hereinafter referred to as the
"Adjustment Shares").

                      (iii)  The  right  to buy  Common  Shares  of the  Company
pursuant to Section  11(a)(ii)  hereof shall not arise as a result of any Person
becoming an Acquiring Person through an acquisition of Common Shares pursuant to
a Permitted Offer.

                      (iv) In lieu of issuing  Common Shares in accordance  with
Section 11(a)(ii) hereof, the Company may, if the Board of Directors  determines
that such action is necessary or appropriate and not contrary to the interest of
holders of Rights (and,  in the event that the number of Common Shares which are
authorized by the Company's  Certificate of Incorporation but not outstanding or
reserved for issuance  for purposes  other than upon  exercise of the Rights are
not sufficient to permit the exercise in full of the Rights, or if any necessary
regulatory approval for such issuance has not been obtained by the Company,  the
Company  shall):  (A) determine the excess of (1) the value of the Common Shares
issuable  upon  the  exercise  of a Right  (the  "Current  Value")  over (2) the
Purchase  Price (such excess,  the "Spread") and (B) with respect to each Right,
make adequate  provision to substitute for such Common Shares,  upon exercise of
the Rights,  (1) cash, (2) a reduction in the Purchase  Price,  (3) other equity
securities of the Company  (including,  without  limitation,  shares or units of
shares of any series of  Preferred  Stock  which the Board of  Directors  of the
Company has deemed to have the same value as Common Shares (such shares or units
of shares of Preferred  Stock are herein called  "common  stock  equivalents")),
except to the extent that the Company has not obtained any necessary stockholder
or regulatory  approval for such issuance,  (4) debt  securities of the Company,
except to the extent that the Company has not obtained any necessary stockholder
or  regulatory  approval  for  such  issuance,  (5)  other  assets  or  (6)  any
combination  of the  foregoing,  having an aggregate  value equal to the Current
Value,  where such aggregate value has been determined by the Board of Directors
of the  Company  based upon the  advice of a  nationally  recognized  investment
banking  firm  selected  by the Board of  Directors  of the  Company;  provided,
however,  if the Company shall not have made adequate provision to deliver value
pursuant to clause (B) above within thirty (30) days  following the later of (x)
the  first  occurrence  of a  Triggering  Event  and (y) the date on  which  the
Company's  right of  redemption  pursuant to Section 23(a) expires (the later of
(x) and (y) being referred to herein as the "Section  11(a)(ii)  Trigger Date"),
then the Company shall be obligated to deliver,  upon the surrender for exercise
of a Right and without  requiring  payment of the Purchase Price,  Common Shares
(to the  extent  available),  except  to the  extent  that the  Company  has not
obtained any necessary stockholder or regulatory approval for such issuance, and
then, if necessary, cash, which shares and/or cash have an aggregate value equal
to the Spread.  If the Board of Directors of the Company shall determine in good
faith  that it is likely  that  sufficient  additional  Common  Shares  could be
authorized  for  issuance  upon  exercise  in full  of the  Rights  or that  any
necessary  regulatory  approval for such issuance  will be obtained,  the thirty
(30) day period set forth above may be extended to the extent necessary, but not
more than ninety (90) days after the Section  11(a)(ii)  Trigger  Date, in order
that the Company may seek  stockholder  approval for the  authorization  of such
additional  shares or take  action  to obtain  such  regulatory  approval  (such
period, as it may be extended,  the "Substitution  Period").  To the extent that
the Company  determines  that some  action  need be taken  pursuant to the first
and/or  second  sentences  of this  Section  11(a)(iv),  the  Company  (x) shall
provide,  subject to Section 7(e) hereof, 



                                      -14-
<PAGE>

that such action  shall apply  uniformly to all  outstanding  Rights and (y) may
suspend  the   exercisability   of  the  Rights  until  the  expiration  of  the
Substitution  Period in order to seek any authorization of additional shares, to
take any action to obtain any required  regulatory approval and/or to decide the
appropriate  form of distribution to be made pursuant to such first sentence and
to determine the value thereof. In the event of any such suspension, the Company
shall issue a public  announcement  stating,  and shall notify the Rights Agent,
that the exercisability of the Rights has been temporarily suspended, as well as
a public announcement,  and notification to the Right Agent, at such time as the
suspension is no longer in effect. For purposes of this Section  11(a)(iv),  the
value of the Common  Shares  shall be the  current  per share  market  price (as
determined pursuant to Section 11(d) hereof) of the Common Shares on the Section
11(a)(ii)  Trigger Date and the value of any "common stock  equivalent" shall be
deemed to have the same value as the Common Shares on such date.

                  (b) In case the Company  shall,  at any time after the date of
this  Agreement,  fix a record  date for the  issuance  of  rights,  options  or
warrants to all holders of Common Shares or of any class or series of Equivalent
Shares  entitling such holders (for a period  expiring  within  forty-five  (45)
calendar days after such record date) to subscribe for or purchase Common Shares
or Equivalent Shares or securities  convertible into Common Shares or Equivalent
Shares at a price  per  share (or  having a  conversion  price per  share,  if a
security convertible into Common Shares or Equivalent Shares) less than the then
current per share market  price of the Common  Shares or  Equivalent  Shares (as
defined in Section  11(d)) on such record  date,  then,  in each such case,  the
Purchase  Price to be in effect  after such record date shall be  determined  by
multiplying the Purchase Price in effect  immediately  prior to such record date
by a fraction,  the  numerator of which shall be the number of Common Shares and
Equivalent  Shares (if any)  outstanding on such record date, plus the number of
Common  Shares or  Equivalent  Shares,  as the case may be, which the  aggregate
offering price of the total number of Common Shares or Equivalent Shares, as the
case may be, 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 Common Shares
and Equivalent  Shares (if any) outstanding on such record date, plus the number
of  additional  Common Shares or  Equivalent  Shares,  as the case may be, to be
offered for  subscription or purchase (or into which the convertible  securities
so to be offered are initially convertible). In case such subscription price may
be paid in a  consideration  part or all of which  shall be in a form other than
cash,  the value of such  consideration  shall be as determined in good faith by
the Board of Directors of the Company, whose determination shall be described in
a statement filed with the Rights Agent and shall be binding on the Rights Agent
and the holders of the Rights.  Common Shares and Equivalent  Shares owned by or
held for the  account of the  Company  shall not be deemed  outstanding  for the
purpose of any such  computation.  Such  adjustment  shall be made  successively
whenever such a record date is fixed, and in the event that such rights, options
or warrants are not so issued,  the  Purchase  Price shall be adjusted to be the
Purchase  Price  which  would then be in effect if such record date had not been
fixed.

                  (c) In case the Company  shall,  at any time after the date of
this  Agreement,  fix a record  date for the  making  of a  distribution  to all
holders  of the  Common  Shares or of any class or series of  Equivalent  Shares
(including any such  distribution  made in connection  with a  consolidation  or
merger in which the  Company is the  continuing  or  surviving  corporation)  of
evidences  of  indebtedness  or  assets  (other  than a regular  quarterly  cash
dividend,  if any,  or a  dividend  


                                      -15-

payable in Common Shares) or subscription rights, options or warrants (excluding
those referred to in Section 11(b)), then, in each such case, 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) of a Common Share or an Equivalent Share on such record
date,  less the fair market value (as  determined  in good faith by the Board of
Directors of the Company,  whose determination shall be described in a statement
filed with the Rights Agent) of the portion of the cash,  assets or evidences of
indebtedness  so to be  distributed or of such  subscription  rights or warrants
applicable  to a Common Share or Equivalent  Share,  as the case may be, and the
denominator of which shall be such current market price (as determined  pursuant
to Section 11(d)  hereof) of a Common Share or  Equivalent  Share on such record
date. 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) For the purpose of any computation  hereunder,  other than
computations made pursuant to Section  11(a)(iv) hereof,  the "current per share
market  price" of any  security (a  "Security"  for the purpose of this  Section
11(d)) on any date shall be deemed to be the average of the daily closing prices
per share of such Security for the thirty (30) consecutive Trading Days (as such
term is hereinafter defined) immediately prior to such date, and for purposes of
computations made pursuant to Section  11(a)(iv) hereof,  the "current per share
market  price" of any  Security on any date shall be deemed to be the average of
the daily closing prices per share of such Security for the ten (10) consecutive
Trading Days  immediately  prior to such date;  provided,  however,  that in the
event that the  current per share  market  price of the  Security is  determined
during a period following the announcement by the issuer of such Security of (i)
a dividend or distribution  on such Security  payable in shares of such Security
or securities convertible into such shares or (ii) any subdivision,  combination
or  reclassification  of such  Security,  and  prior  to the  expiration  of the
requisite  thirty  (30)  Trading Day or ten (10)  Trading Day period,  after the
ex-dividend date for such dividend or distribution,  or the record date for such
subdivision,  combination or reclassification,  then, and in each such case, the
current per share  market price shall be  appropriately  adjusted to reflect the
current market price per share  equivalent of such  Security.  The closing price
for each day shall be the last sale price, regular way, or, in case no such sale
takes  place on such day,  the  average  of the  closing  bid and asked  prices,
regular  way,  in  either  case  as  reported  in  the  principal   consolidated
transaction  reporting  system with respect to securities  listed or admitted to
trading  on the New York Stock  Exchange  or, if the  Security  is not listed or
admitted to trading on the New York Stock Exchange, as reported in the principal
consolidated  transaction  reporting system with respect to securities listed on
the principal  national  securities  exchange on which the Security is listed or
admitted to trading or, if the  Security is not listed or admitted to trading on
any  national  securities  exchange,  the last sale  price or, if such last sale
price is not  reported,  the average of the high bid and low asked prices in the
over-the-counter  market, as reported by the National  Association of Securities
Dealers Automated Quotation  ("NASDAQ") system or such other system then in use,
or, if on any such date the Security is not quoted by any such organization, the
average of the  closing  bid and asked  prices as  furnished  by a  professional
market maker making a market in the Security  selected by the Board of Directors
of the  Company.  If on any such date no market  maker is making a market in the
Common Shares,  



                                      -16-
<PAGE>

the fair value of such  shares on such date as  determined  in good faith by the
Board of Directors of the Company  shall be used.  The term  "Trading Day" shall
mean a day on which the  principal  national  securities  exchange  on which the
Security  is  listed or  admitted  to  trading  is open for the  transaction  of
business  or, if the  Security  is not  listed or  admitted  to  trading  on any
national  securities  exchange,  a Business  Day.  If the Common  Shares are not
publicly  held or so listed or traded,  "current per share  market  price" shall
mean the fair  value  per  share as  determined  in good  faith by the  Board of
Directors of the Company,  whose determination shall be described in a statement
filed with the Rights Agent and shall be conclusive for all purposes.

                  (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  ten-thousandth  of a Common  Share or other
share  or one  hundred-thousandth  of a  Preferred  Share,  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
(3) years from the date of the  transaction  which  requires such  adjustment or
(ii) the Expiration Date.

                  (f) If as a result of an  adjustment  made pursuant to Section
11(a) or 13(a) hereof, the holder of any Right thereafter exercised shall become
entitled to receive any shares of capital  stock  other than  Preferred  Shares,
thereafter  the number of such other shares so  receivable  upon exercise of any
Right  and if  required,  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 Common Shares  contained in
Sections  11(a),  (b),  (c),  (e),  (h),  (i),  (j),  (k),  (1) and (m), and the
provisions of Sections 7, 9, 10, 13 and 14 with respect to the Preferred  Shares
shall apply on like terms to any such other shares.

                  (g) All Rights originally issued by the Company  subsequent to
any adjustment  made to the Purchase Price hereunder shall evidence the right to
purchase,  at the adjusted  Purchase Price, the number of  one-thousandths  of a
Preferred  Share  purchasable  from time to time  hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

                  (h) Unless the Company  shall have  exercised  its election as
provided in Section  11(i),  upon each  adjustment  of the  Purchase  Price as a
result  of the  calculations  made in  Section  11(b),  each  Right  outstanding
immediately prior to the making of such adjustment shall thereafter evidence the
right to purchase,  at the  adjusted  Purchase  Price,  that number of Preferred
Shares (calculated to the nearest one hundred-thousandth of a share) obtained by
(i)  multiplying  (x)  the  number  of  Preferred  Shares  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 as a result of the calculations made in Section
11(b) to adjust the number of 



                                      -17-
<PAGE>

Rights,  in  substitution  for any adjustment in the number of Preferred  Shares
purchasable upon the exercise of a Right.  Each of the Rights  outstanding after
such  adjustment of the number of Rights shall be exercisable  for the number of
one-thousandths  of  a  Preferred  Share  for  which  a  Right  was  exercisable
immediately  prior to such  adjustment.  Each Right held of record prior to such
adjustment  of  the  number  of  Rights  shall  become  that  number  of  Rights
(calculated  to the nearest  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,  and shall notify the Rights Agent, 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 (10) days later than the date of the  public  announcement.  If Rights
Certificates  have been  issued,  upon each  adjustment  of the number of Rights
pursuant to this Section 11(i),  the Company shall,  as promptly as practicable,
cause to be  distributed  to  holders of record of Rights  Certificates  on such
record date Rights  Certificates  evidencing,  subject to Section 14 hereof, the
additional  Rights to which such  holders  shall be entitled as a result of such
adjustment,  or, at the option of the Company,  shall cause to be distributed to
such  holders  of  record  in  substitution   and  replacement  for  the  Rights
Certificates  held by such  holders  prior to the date of  adjustment,  and upon
surrender  thereof,  if  required  by  the  Company,   new  Rights  Certificates
evidencing  all the Rights to which such  holders  shall be entitled  after such
adjustment.  Rights Certificates so to be distributed shall be issued,  executed
and countersigned in the manner provided for herein (and may bear, at the option
of the Company,  the adjusted  Purchase  Price) and shall be  registered  in the
names of the  holders  of record  of  Rights  Certificates  on the  record  date
specified in the public announcement.

                  (j)  Irrespective  of any adjustment or change in the Purchase
Price or the  number of  Preferred  Shares  issuable  upon the  exercise  of the
Rights, the Rights  Certificates  theretofore and thereafter issued may continue
to express the Purchase Price per one  one-thousandth  of a Preferred  Share and
the number of  one-thousandths  of a Preferred Share 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 par or stated value, if any, of the number
of  one-thousandths  of a Preferred  Share 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 as
fully  paid  and  nonassessable  shares  such  number  of  one-thousandths  of a
Preferred Share at such adjusted Purchase Price.

                  (1) In any case in which this Section 11 shall require that an
adjustment  in the  Purchase  Price be made  effective as of a record date for a
specified  event,  the Company may elect to defer until the  occurrence  of such
event the issuing to the holder of any Right exercised after such record date of
the number of  one-thousandths  of a Preferred  Share and other capital stock or
securities  of the Company,  if any,  issuable upon such exercise over and above
the number of  one-thousandths  of a Preferred  Share and other capital stock or
securities of the Company,  if any,  issuable upon such exercise on the basis of
the Purchase Price in effect prior to such adjustment;  provided,  however, that
the  Company  shall  deliver  to such  holder a due  bill or  other  appropriate


                                      -18-
<PAGE>

instrument  evidencing  such holder's  right to receive such  additional  shares
(fractional  or  otherwise)  upon the  occurrence  of the event  requiring  such
adjustment.

                  (m)   Anything   in   this   Section   11  to   the   contrary
notwithstanding,  prior to the Distribution  Date, the Company shall be entitled
to make such reductions in the Purchase Price, in addition to those  adjustments
expressly  required by this Section 11, as and to the extent that it in its sole
discretion  shall determine to be advisable in order that any (i)  consolidation
or subdivision of the Preferred or Common Shares,  (ii) issuance wholly for cash
of any Preferred or Common Shares at less than the current  market price,  (iii)
issuance  wholly for cash of Preferred or Common Shares or  securities  which by
their terms are convertible into or exchangeable for Preferred or Common Shares,
(iv) stock dividends or (v) issuance of rights,  options or warrants referred to
in this Section 11, hereafter made by the Company to holders of its Preferred or
Common Shares shall not be taxable to such stockholders.

                  (n) The Company covenants and agrees that it shall not, at any
time after the Distribution Date, effect or permit to occur any Triggering Event
or Section 13 Event,  if (i) at the time or  immediately  after such  Triggering
Event or Section 13 Event 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 (ii) prior to,  simultaneously  with or immediately after such Section
13 Event, the stockholders of the Person who constitutes,  or would  constitute,
the "Principal Party" for purposes of Section 13(b) hereof shall have received a
distribution of Rights  previously owned by such Person or any of its Affiliates
and Associates.

                  (o)  The  Company   covenants  and  agrees  that,   after  the
Distribution  Date,  it will not,  except as  permitted by Sections 23, 24 or 27
hereof,  take (or permit to be taken)  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 the  Company  shall at any time after the date of
this  Agreement  (A)  declare a  dividend  on the  Preferred  Shares  payable in
Preferred Shares,  (B) subdivide the outstanding  Preferred Shares,  (C) combine
the  outstanding  Preferred  Shares (by reverse stock split or otherwise) into a
smaller number of Preferred Shares, or (D) issue any shares of its capital stock
in  a   reclassification   of  the   Preferred   Shares   (including   any  such
reclassification  in  connection  with a  consolidation  or  merger in which the
Company is the continuing or surviving  corporation),  then, in each such event,
except as otherwise  provided in this  Section 11 and Section  7(e) hereof:  (1)
each of the Rights  outstanding at the time of the record date for such dividend
or the effective date of such subdivision, combination or reclassification shall
be proportionately  adjusted to that number of Rights (calculated to the nearest
one  ten-thousandth  (1/10,000) of a Right) equal to a fraction  (the  "Exchange
Fraction"), the numerator of which shall be the total number of Preferred Shares
or shares of capital  stock  issued in such  reclassification  of the  Preferred
Shares outstanding  immediately following such time and the denominator of which
shall be the total number of Preferred Shares  outstanding  immediately prior to
such time, and the number of Rights that shall thereafter be issued with respect
to each Common Share or share of other  capital  stock that shall be issued in a
reclassification  of the Common Shares prior to the  Distribution  Date shall be
equal to the 



                                      -19-
<PAGE>

total number of  outstanding  Rights  immediately  after such event (as adjusted
pursuant to this clause (1)) divided by the total number of  outstanding  Common
Shares or shares of such  other  capital  stock  immediately  after  such  event
(subject to further  adjustment  pursuant to the provisions of this  Agreement);
(2) 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  shall be adjusted so that the Purchase Price  thereafter shall
equal the result  obtained by dividing the Purchase Price in effect  immediately
prior to such time by the Exchange Fraction; provided, however, that in no event
shall the  consideration  to be paid upon the exercise of one Right be less than
the aggregate  par value of the shares of capital stock of the Company  issuable
upon  exercise  of such  Right;  and  (3) the  number  of  one-thousandths  of a
Preferred  Share or share of such other capital stock issuable upon the exercise
of each Right shall remain unchanged  immediately  after such event, but, in the
event of a  reclassification,  the kind of shares  issuable upon the exercise of
each Right immediately after such  reclassification  shall be adjusted to be the
kind of shares of such  other  capital  stock  issued in such  reclassification,
rather than Preferred Shares.

         Section 12. Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an  adjustment  is made as  provided in Sections 11 and 13 hereof,  the
Company shall promptly (a) prepare a certificate  setting forth such  adjustment
and a brief statement of the facts accounting for such adjustment, (b) file with
the Rights Agent and with each transfer agent for the Preferred Shares a copy of
such certificate and (c) mail a brief summary thereof to each holder of a Rights
Certificate in accordance with Section 26 hereof.  Notwithstanding the foregoing
sentence,  the  failure of the Company to make such  certification  or give such
notice shall not affect the validity of such  adjustment  or the force or effect
of the  requirement  for  such  adjustment.  The  Rights  Agent  shall  be fully
protected in relying on any such  certificate  and on any  adjustment  contained
therein and shall not be deemed to have knowledge of 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 Shares Acquisition Date,
directly or indirectly:

                           (i) the Company shall consolidate with, or merge with
and into,  any  other  Person  (other  than a  Subsidiary  of the  Company  in a
transaction  the  principal   purpose  of  which  is  to  change  the  state  of
incorporation of the Company or that complies with Section 11(o) hereof);

                           (ii)  any  Person  (other  than a  Subsidiary  of the
Company  in a  transaction  that  complies  with  Section  11(o)  hereof)  shall
consolidate with the Company, or merge with and into the Company and the Company
shall be the  continuing  or  surviving  corporation  of such  consolidation  or
merger; or

                           (iii) the Company  shall sell or  otherwise  transfer
(or one or more of its Subsidiaries shall sell or otherwise transfer), in one or
more transactions, assets or earning power aggregating 50% or more of the assets
or earning power of the Company and its  Subsidiaries  (taken as a whole) to any
other  Person or Persons  (other  than the  Company or one or more of its 


                                      -20-
<PAGE>

wholly owned  Subsidiaries in one or more  transactions,  each of which complies
with Section 11(o) hereof),

                                    then,   and  in  each  such   case,   proper
provision shall be made so that

                                    (A)  each  holder  of  a  Right  (except  as
otherwise provided herein) shall thereafter have the right to receive,  upon the
exercise thereof in accordance with the terms of this Agreement,  such number of
validly authorized and issued, fully paid and nonassessable Common Shares of the
Principal  Party (as  hereinafter  defined),  free of any  liens,  encumbrances,
rights of first refusal or other adverse claims, as shall be equal to the result
obtained by (1)  multiplying  the then current  Purchase  Price by the number of
one-thousandths  of  a  Preferred  Share  for  which  a  Right  was  exercisable
immediately  prior to the first  occurrence  of a  Section  13 Event  (or,  if a
Triggering  Event has  occurred  prior to the first  occurrence  of a Section 13
Event,  multiplying the number of such  one-thousandths of a Preferred Share for
which a Right was  exercisable  immediately  prior to the first  occurrence of a
Triggering Event by the Purchase Price in effect immediately prior to such first
occurrence) and (2) dividing that product (which, following the first occurrence
of a Section 13 Event,  shall be referred to as the "Total  Exercise  Price" for
each Right and for all  purposes  of this  Agreement)  by 50% of the current per
share market price  (determined  pursuant to Section 11(d) hereof) of the Common
Shares of such Principal  Party on the date of  consummation  of such Section 13
Event;

                                    (B) 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;

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

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

                  (b)  "Principal   Party"  shall  mean,  in  the  case  of  any
transaction  described in clause (i), (ii) or (iii) of Section 13(a), the Person
referred to therein or such Person's successor,  including,  if applicable,  the
Company, if it is the surviving  corporation),  provided,  however,  that in any
such case,  (i) if such  Person is a direct or  indirect  Subsidiary  of another
Person, "Principal Party" shall refer to such other Person and (ii) in case such
Person  is a  Subsidiary,  directly  or  indirectly,  of more  than one  Person,
"Principal  Party" shall refer to whichever of such Persons is the issuer of the
Common Shares having the greatest aggregate value, and provided,  further,  that
for purposes of transactions described in clause (iii) hereof, "Principal Party"
shall  refer to that  Person  receiving  the  greatest  portion of the assets or
earning power transferred pursuant to such transaction or transactions.


                                      -21-
<PAGE>

                  (c) If, for any reason,  the Rights  cannot be  exercised  for
Common Shares of such Principal  Party as provided in Section  13(a),  then each
holder of Rights  shall have the right to exchange its Rights for cash from such
Principal  Party in an amount equal to the number of Common Shares that it would
otherwise  be  entitled to  purchase  times 50% of the current per share  market
price, as determined  pursuant to Section 11(d) hereof, of such Common Shares of
such Principal Party. If, for any reason,  the foregoing  formulation  cannot be
applied to  determine  the cash amount  into which the Rights are  exchangeable,
then the Board of  Directors,  based upon the  advice of one or more  nationally
recognized  investment  banking  firms,  and based  upon the total  value of the
Company,  shall  determine  such  amount  reasonably  and with good faith to the
holders  of Rights.  Any such  determination  shall be final and  binding on the
Rights Agent.

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

                  (e) The  Company  shall not  consummate  any  Section 13 Event
unless the Principal Party shall have a sufficient  number of authorized  Common
Shares that have not been issued or reserved for issuance to permit the exercise
in full of the  Rights in  accordance  with this  Section  13 and  unless  prior
thereto the Company and such issuer  shall have  executed  and  delivered to the
Rights Agent a  supplemental  agreement  confirming  that such  Principal  Party
shall,  upon  consummation  of such Section 13 Event,  assume this  Agreement in
accordance with Sections 13(a) and (b) hereof,  that all rights of first refusal
or  preemptive  rights in  respect  of the  issuance  of  Common  Shares of such
Principal Party upon exercise of outstanding Rights have been waived, that there
are no rights, warrants, instruments or securities outstanding or any agreements
or  arrangements  which, as a result of the  consummation  of such  transaction,
would eliminate or substantially  diminish the benefits  intended to be afforded
by the  Rights and that such  transaction  shall not result in a default by such
Principal  Party under this  Agreement,  and further  providing that, as soon as
practicable after the date of such Section 13 Event, such Principal Party will:

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

                           (ii) use its best  efforts to list (or  continue  the
listing  of) the Rights and the  securities  purchasable  upon  exercise  of the
Rights on a national securities exchange or to meet the eligibility requirements
for quotation on NASDAQ; and

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

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

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

         Section 14. Fractional Rights and Fractional Shares.

                  (a) The Company  shall not be required to issue  fractions  of
Rights or to distribute Rights  Certificates that evidence fractional Rights. In
lieu of such fractional Rights, there shall be paid to the registered holders of
the Rights  Certificates  with  regard to which  such  fractional  Rights  would
otherwise  be  issuable,  an amount in cash  equal to the same  fraction  of the
current  market value of a whole Right.  For the purposes of this Section 14(a),
the current  market  value of a whole  Right  shall be the closing  price of the
Rights  for  the  Trading  Day  immediately  prior  to the  date on  which  such
fractional Rights would have been otherwise issuable,  as determined pursuant to
the second sentence of Section 11(d) hereof.

                  (b) The Company  shall not be required to issue  fractions  of
Preferred  Shares  (other than  fractions  that are  integral  multiples  of one
one-thousandth  of a  Preferred  Share)  upon  exercise  of  the  Rights  or  to
distribute  certificates which evidence fractional  Preferred Shares (other than
fractions  that are  integral  multiples  of one  one-thousandth  of a Preferred
Share). In lieu of fractional  Preferred Shares that are not integral  multiples
of one  one-thousandth  of a  Preferred  Share,  the  Company  shall  pay to the
registered holders of Rights  Certificates at the time such Rights are exercised
as herein  provided an amount in cash equal to the same  fraction of the current
market value of a Common Share.  For purposes of this Section 14(b), the current
market value of a Common Share shall be the closing  price of a Common Share (as
determined  pursuant  to the second  sentence of Section  11(d)  hereof) for the
Trading Day immediately prior to the date of such exercise.

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

         Section 15.  Rights of Action.  All rights of action in respect of this
Agreement,  excepting  the  rights of action  given to the  Rights  Agent  under
Section 18 hereof, are vested in the respective registered holders of the Rights
Certificates (and, prior to the Distribution Date, the 



                                      -23-
<PAGE>

registered  holders  of the Common  Shares);  and any  registered  holder of any
Rights  Certificate (or, prior to the Distribution  Date, of the Common Shares),
without  the  consent of the Rights  Agent or of the holder of any other  Rights
Certificate (or, prior to the Distribution Date, of the Common Shares),  may, in
his or her own behalf and for his or her own benefit, enforce, and may institute
and maintain any suit, action or proceeding  against the Company to enforce,  or
otherwise  act in respect of, his or her 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 will be entitled to  specific  performance  of the  obligations  under,  and
injunctive relief against actual or threatened violations of, the obligations of
any Person subject to this Agreement.

         Section 16.  Agreement of Rights  Holders.  Every holder of a Right, by
accepting  the same,  consents  and agrees with the Company and 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 the Common Shares;

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

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

         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 Preferred Shares or any
other  securities  of the  Company  which  may at any  time be  issuable  on the
exercise of the Rights represented  thereby, nor shall anything contained herein
or in any  Rights  Certificate  be  construed  to confer  upon the holder of any
Rights  Certificate,  as such, any of the rights of a stockholder of the Company
or any right to vote for the election of 



                                      -24-
<PAGE>

directors or upon any matter  submitted to stockholders at any meeting  thereof,
or to give or withhold consent to any corporate  action, or to receive notice of
meetings or other actions affecting  stockholders (except as provided in Section
25 hereof), or to receive dividends or subscription rights, or otherwise,  until
the  Right or  Rights  evidenced  by such  Rights  Certificate  shall  have been
exercised in accordance with the provisions hereof.

         Section 18. Concerning the Rights Agent.

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

                  (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 the Common Shares or for other securities
of the  Company,  instrument  of  assignment  or  transfer,  power of  attorney,
endorsement,   affidavit,  letter,  notice,  direction,   consent,  certificate,
statement  or other  paper or  document  believed  by it to be genuine and to be
signed and  executed  by the  proper  Person or Persons  and,  where  necessary,
verified or  acknowledged,  or otherwise upon the advice of counsel as set forth
in Section 20 hereof.

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

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


                                      -25-
<PAGE>

                  (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  expressly  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 of its
selection (who may be legal counsel for the Company),  and the opinion or advice
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 or advice.

                  (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 per share 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  herein  specifically
prescribed)  may be  deemed  to be  conclusively  proved  and  established  by a
certificate  signed by any one of the Chairman of the Board, the Chief Executive
Officer,  the President,  any Vice President,  the Chief Financial Officer,  the
Secretary or any Assistant  Secretary of the Company and delivered to the Rights
Agent; and such certificate shall be full  authorization to the Rights Agent for
any action  taken or suffered in good faith by it under the  provisions  of this
Agreement in reliance upon such certificate.

                  (c) The Rights Agent shall be liable  hereunder to the Company
and any  other  Person  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  (except  its  countersignature  thereof) or be required to
verify the same, but all such statements and recitals are and shall be deemed to
have been made by the Company only.

                  (e) The Rights Agent shall not be under any  responsibility in
respect of the validity of this  Agreement or the execution and delivery  hereof
(except  the due  execution  hereof by the  Rights  Agent) or in  respect of the
validity or execution  of any Rights  Certificate  (except its  countersignature
thereof);  nor shall it be  responsible  for any  breach by the  Company  of any
covenant or condition  contained in this Agreement or in any Rights Certificate;
nor shall it be responsible for any change in the  exercisability  of the Rights
or any adjustment in the terms of the Rights  (including  the manner,  method or
amount  thereof)  provided  for  in  Sections  3,  11,  13,  23 or  24,  or  the
ascertaining  of the  existence  of facts that would  require any such change or
adjustment  


                                      -26-
<PAGE>

(except with respect to the exercise of Rights evidenced by Rights  Certificates
after receipt by the Rights Agent of a certificate furnished pursuant to Section
12 describing such change or  adjustment);  nor shall it by any act hereunder be
deemed  to make  any  representation  or  warranty  as to the  authorization  or
reservation of any Preferred  Shares to be issued  pursuant to this Agreement or
any Rights  Certificate or as to whether any Preferred Shares will, when issued,
be validly authorized and issued, fully paid and nonassessable.

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

                  (g) The Rights  Agent is hereby  authorized  and  directed  to
accept instructions with respect to the performance of its duties hereunder from
any  one  of the  Chairman  of the  Board,  the  Chief  Executive  Officer,  the
President, any Vice President, the Chief Financial Officer, the Secretary or any
Assistant Secretary of the Company,  and to apply to such officers for advice or
instructions in connection  with its duties,  and it shall not be liable for any
action taken or suffered by it in good faith in accordance with  instructions of
any  such  officer  or  for  any  delay  in  acting  while   waiting  for  those
instructions.  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 (5) Business Days after the
date any 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 stockholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the Company or become pecuniarily interested in any transaction in
which the  Company  may be  interested,  or  contract  with or lend money to the
Company or otherwise  act as fully and freely as though it were not Rights Agent
under this Agreement. Nothing herein shall preclude the Rights Agent from acting
in any other capacity for the Company or for any other legal entity.

                  (i) The  Rights  Agent may  execute  and  exercise  any of the
rights or powers hereby vested in it or perform any duty hereunder either itself
or by or through  its  attorneys  or agents,  and the Rights  Agent shall not be
answerable or  accountable  for any act,  default,  neglect or misconduct of any
such attorneys or agents or for any loss to the Company  resulting from any such
act, default,  neglect or misconduct,  provided reasonable care was exercised in
the selection and continued employment thereof.

                  (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  


                                      -27-
<PAGE>

hereunder or in the exercise of its rights if there shall be reasonable  grounds
for believing that repayment of such funds or adequate  indemnification  against
such risk or liability is not reasonably assured to it.

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

         Section 21. Change of Rights  Agent.  The Rights Agent or any successor
Rights Agent may resign and be discharged  from its duties under this  Agreement
upon  thirty  (30) days'  notice in writing  mailed to the  Company  and to each
transfer  agent of the  Preferred  Shares and the Common Shares by registered or
certified mail. The Company may remove the Rights Agent or any successor  Rights
Agent upon thirty (30) days'  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  Shares and the Common Shares by registered or certified  mail. If the
Rights Agent shall resign or be removed or shall otherwise  become  incapable of
acting,  the Company  shall  appoint a  successor  to the Rights  Agent.  If the
Company shall fail to make such appointment  within a period of thirty (30) days
after giving  notice of such removal or after it has been notified in writing of
such resignation or incapacity by the resigning or incapacitated Rights Agent or
by the holder of a Rights  Certificate (who shall, with such notice,  submit his
or her Rights Certificate for inspection by the Company),  then the Rights Agent
or the  registered  holder of any Rights  Certificate  may apply to any court of
competent  jurisdiction for the appointment of a new Rights Agent. Any successor
Rights Agent,  whether  appointed by the Company or by such a court,  shall be a
corporation  organized and doing business under the laws of the United States or
of any state of the United States,  in good standing,  which is authorized under
such laws to exercise  corporate  trust or  stockholder  services  powers and is
subject to supervision  or  examination by federal or state  authority and which
has at the time of its  appointment  as  Rights  Agent a  combined  capital  and
surplus of at least $50 million.  After appointment,  the successor Rights Agent
shall be vested with the same powers,  rights, duties and responsibilities as if
it had been  originally  named as Rights Agent without  further act or deed; but
the predecessor  Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance,  conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such  appointment,  the Company shall file notice
thereof in writing with the predecessor  Rights Agent and each transfer agent of
the Preferred Shares and the Common Shares, and mail a notice thereof in writing
to the registered holders of the Rights Certificates. Failure to give any notice
provided  for in this  Section 21,  however,  or any defect  therein,  shall not
affect the  legality  or validity  of the  resignation  or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.

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


                                      -28-
<PAGE>

accordance  with the provisions of this  Agreement.  In addition,  in connection
with the issuance or sale of Common Shares following the  Distribution  Date and
prior to the redemption or expiration of the Rights, the Company (a) shall, with
respect to Common  Shares 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 the convertible subordinated debentures of the Company
outstanding  at the date hereof 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 the Board of Directors of the Company,  issue
Rights Certificates  representing the appropriate number of Rights in connection
with  such  issuance  or  sale;  provided,  however,  that  (i) no  such  Rights
Certificate  shall be issued and this sentence  shall be null and void ab initio
if, and to the extent  that,  such  issuance  or this  sentence  would  create a
significant  risk of or result  in  material  adverse  tax  consequences  to the
Company or the Person to whom such Rights  Certificate  would be issued or would
create a significant  risk of or result in such  options' or employee  plans' or
arrangements'  failing to qualify for otherwise  available special tax treatment
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.

                  (a) The Company  may,  at its option and with the  approval of
the  Board of  Directors,  at any time  prior to the  Close of  Business  on the
earlier of (i) the tenth day following the Shares Acquisition Date or such later
date as may be determined by action of a majority of Continuing  Directors  then
in office and  publicly  announced  by the Company or (ii) the Final  Expiration
Date,  redeem  all but not  less  than  all the  then  outstanding  Rights  at a
redemption price of $0.01 per Right, appropriately adjusted to reflect any stock
split,  stock dividend or similar  transaction  occurring  after the date hereof
(such redemption  price being herein referred to as the "Redemption  Price") and
the Company may, at its option, pay the Redemption Price either in Common Shares
(based on the current per share market price thereof (as determined  pursuant to
Section 11(d) hereof) at the time of redemption) or cash; provided,  however, if
the Board of Directors of the Company authorizes  redemption of the Rights on or
after  the time a  Person  becomes  an  Acquiring  Person,  then  there  must be
Continuing  Directors  then in office and such  authorization  shall require the
concurrence of a majority of such Continuing Directors.

                  (b)  Immediately  upon the action of the Board of Directors of
the Company ordering the redemption of the Rights,  evidence of which shall have
been filed with the Rights Agent, and without any further action and without any
notice,  the right to  exercise  the Rights  will  terminate  and the only right
thereafter  of the holders of Rights shall be to receive the  Redemption  Price.
Within  ten (10) days after the action of the Board of  Directors  ordering  the
redemption of the Rights,  the Company  shall give notice of such  redemption to
the Rights Agent and the holders of the then outstanding  Rights by mailing such
notice to all such  holders  at their last  addresses  as they  appear  upon the
registry  books of the Rights Agent or, prior to the  Distribution  Date, on the
registry books of the transfer agent for the Common Shares.  Any notice which is
mailed in the manner herein  provided shall be deemed given,  whether or not the
holder receives the notice. Each such notice of redemption will state the method
by which the payment of the Redemption  Price will be made.  Neither the Company
nor any of its  Affiliates  or  Associates  may redeem,  acquire or purchase for
value any Rights at any time in any  manner  other  than that  specifically  set

                                      -29-
<PAGE>

forth in this Section 23 or in Section 24 hereof,  and other than in  connection
with the purchase of Common Shares prior to the Distribution Date.

         Section 24. Exchange.

                  (a) Subject to applicable  laws,  rules and  regulations,  and
subject to  subsection  (c) below,  the Company may, at its option,  by majority
vote of the Board of Directors and a majority vote of the Continuing  Directors,
at any time after the occurrence of a Triggering Event,  exchange all or part of
the then outstanding and exercisable Rights (which shall not include Rights that
have become void  pursuant to the  provisions of Section 7(e) hereof) for Common
Shares  at an  exchange  ratio of one  Common  Share  per  Right,  appropriately
adjusted  to reflect any stock  split,  stock  dividend  or similar  transaction
occurring after the date hereof (such exchange ratio being hereinafter  referred
to as the "Ratio of  Exchange").  Notwithstanding  the  foregoing,  the Board of
Directors  shall not be empowered to effect such  exchange at any time after any
Person  (other than the Company,  any  Subsidiary  of the Company,  any employee
benefit plan of the Company or any such Subsidiary, or any entity holding Common
Shares  for or  pursuant  to the  terms of any  such  plan),  together  with all
Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or
more of the Common Shares then outstanding.

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

                  (c) In the event that  there  shall not be  sufficient  Common
Shares  issued but not  outstanding  or  authorized  but  unissued to permit any
exchange of Rights as contemplated in accordance with Section 24(a), the Company
shall either take such action as may be necessary to authorize additional Common
Shares for issuance upon exchange of the Rights or alternatively,  at the option
of a majority of the Board of Directors, with respect to each Right (i) pay cash
in an amount equal to the Current  Value (as  hereinafter  defined),  in lieu of
issuing  Common  Shares  in  exchange  therefor,  or (ii)  issue  debt or equity
securities or a combination thereof,  having a value equal to the Current Value,
in lieu of issuing  common  Shares in exchange  for each such  Right,  where the
value  of  such  securities  shall  be  determined  by a  nationally  recognized
investment  banking firm  selected by the Board of Directors by majority vote of
the Board of Directors,  or (iii)  deliver any  combination  of cash,  property,
Common Shares and/or other securities  having a 



                                      -30-
<PAGE>

value equal to the Current  Value in exchange  for each Right.  For  purposes of
this Section 24(c) only, the Current Value shall mean the product of the current
per share market price of Common Shares (determined pursuant to Section 11(d) on
the date of the occurrence of the event  described  above in  subparagraph  (a))
multiplied by the number of Common Shares for which the Right otherwise would be
exchangeable if there were sufficient shares  available.  To the extent that the
Company  determines that some action need be taken pursuant to clauses (i), (ii)
or (iii) of this Section 24(c),  the Board of Directors may temporarily  suspend
the exercisability of the Rights for a period of up to sixty (60) days following
the date on which the event  described in Section 24(a) shall have occurred,  in
order to seek any authorization of additional Common Shares and/or to decide the
appropriate  form of distribution to be made pursuant to the above provision and
to determine the value thereof. In the event of any such suspension, the Company
shall issue a public announcement, and shall send a written notice to the Rights
Agent,  stating  that the  exercisability  of the  Rights  has been  temporarily
suspended.

                  (d) The Company  shall not be required to issue  fractions  of
Common Shares or to distribute  certificates  that  evidence  fractional  Common
Shares.  In lieu of such  fractional  Common Shares,  there shall be paid to the
registered  holders  of the  Rights  Certificates  with  regard  to  which  such
fractional Common Shares would otherwise be issuable, an amount in cash equal to
the same  fraction of the current per share market value of a whole Common Share
(as determined pursuant to the second sentence of Section 11(d) hereof).

                  (e) The Company  may, at its option,  by majority  vote of the
Board of  Directors,  at any time  before any  Person  has  become an  Acquiring
Person,  exchange  all or part of the then  outstanding  Rights  for  rights  of
substantially  equivalent value, as determined reasonably and with good faith by
the  Board  of  Directors,  based  upon  the  advice  of one or more  nationally
recognized investment banking firms.

                  (f)  Immediately  upon the  action of the  Board of  Directors
ordering the exchange of any Rights  pursuant to subsection  (e) of this Section
24 and without any further action and without any notice,  the right to exercise
such Rights shall  terminate  and the only right  thereafter of a holder of such
Rights  shall be to receive  that number of rights in  exchange  therefor as has
been  determined by the Board of Directors in  accordance  with  subsection  (e)
above.  The Company shall give public  notice,  and written notice to the Rights
Agent, of any such exchange; provided, however, that the failure to give, or any
defect in,  such notice  shall not affect the  validity  of such  exchange.  The
Company  shall 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
transfer agent for the Common Shares of the Company.  Any notice which is mailed
in the manner herein  provided shall be deemed given,  whether or not the holder
receives the notice. Each such notice of exchange will state the method by which
the exchange of the Rights will be effected.

         Section 25. Notice of Certain Events.

                  (a) In case the Company  shall  propose to effect or permit to
occur any Section 13 Event, the Company shall give notice thereof to each holder
of Rights,  and to the Rights  Agent,  in  accordance  with Section 26 hereof at
least twenty (20) days prior to occurrence of such Section 13 Event.

                  (b) In case any  Triggering  Event or Section  13 Event  shall
occur,  then,  in any  such  case,  the  Company  shall  as soon as  practicable
thereafter give to each holder of a Rights Certificate, and to the Rights Agent,
in accordance with Section 26 hereof,  a notice of the occurrence of such event,
which shall  specify the event and the  consequences  of the event to holders of
Rights under Sections 11(a)(ii) and 13 hereof.

         Section 26. Notices. Notices or demands authorized by this Agreement to
be given or made by the Rights Agent or by the holder of any Rights  Certificate

         Section 27. Supplements and Amendments. Prior to the Distribution Date,
the Company may  supplement or amend this  Agreement in any respect  without the
approval of any holders of Rights and the Rights Agent shall,  if the Company so
directs,  execute such supplement or amendment.  From and after the Distribution
Date, the Company and the Rights Agent may from time to time supplement or amend
this  Agreement  without  the  approval of any holders of Rights in order to (i)
cure any ambiguity,  (ii) correct or supplement any provision  contained  herein

shorten or lengthen any time period hereunder (which  lengthening or shortening,
following the first  occurrence of an event set forth in clauses (i) and (ii) of
the  proviso to  Section  23(a)  hereof,  shall be  effective  only if there are
Continuing  Directors  and shall require the  concurrence  of a majority of such
Continuing  Directors) or (iv) to change or supplement the provisions  hereunder
in any manner that the Company may deem  necessary or  desirable  and that shall
not  adversely  affect the  interests  of the  holders of Rights  (other than an
Acquiring Person or an Affiliate or Associate of an Acquiring Person); provided,
this  Agreement  may not be  supplemented  or amended to  lengthen,  pursuant to
clause (iii) of this sentence, (A) a time period relating to when the Rights 



                                      -32-
<PAGE>

may be  redeemed at such time as the Rights are not then  redeemable  or (B) any
other time period  unless  such  lengthening  is for the purpose of  protecting,
enhancing or  clarifying  the rights of,  and/or the benefits to, the holders of
Rights.  Upon the delivery of a certificate  from an appropriate  officer of the
Company that states that the proposed  supplement  or amendment is in compliance
with  the  terms of this  Section  27,  the  Rights  Agent  shall  execute  such
supplement or amendment.  Prior to the  Distribution  Date, the interests of the
holders of Rights shall be deemed  coincident  with the interests of the holders
of Common Shares. Notwithstanding any other provision hereof, the Rights Agent's
consent must be obtained regarding any amendment or supplement  pursuant to this
Section 27 which alters the Rights Agent's rights or duties, which consent shall
not be unreasonably withheld.

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

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

         Section 30. Benefits of this Agreement.

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

         Section  31.  Severability.   If  any  term,  provision,   covenant  or
restriction  of this Agreement is held by a court of competent  jurisdiction  or
other  authority  to be invalid,  void or  unenforceable,  the  remainder of the
terms, provisions,  covenants and restrictions of this 



                                      -33-
<PAGE>

Agreement shall remain in full force and effect and shall in no way be affected,
impaired or invalidated;  provided,  however,  that notwithstanding  anything in
this  Agreement  to the  contrary,  if any such  term,  provision,  covenant  or
restriction  is  held  by  such  court  or  authority  to be  invalid,  void  or
unenforceable  and the Board of Directors of the Company  determines in its good
faith  judgment that severing the invalid  language  from this  Agreement  would
adversely  affect  the  purpose  or  effect  of this  Agreement,  the  right  of
redemption  set forth in Section  23 hereof  shall be  reinstated  and shall not
expire until the close of business on the tenth day  following  the date of such
determination by the Board of Directors.

         Section  32.  Governing  Law.  This  Agreement  and each Right and each
Rights  Certificate issued hereunder shall be deemed to be a contract made under
the laws of the State of Delaware and for all purposes  shall be governed by and
construed in accordance  with the laws of such State  applicable to contracts to
be made and performed entirely within such State.

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

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

         Pursuant to Section 151 and Section 103 of the General  Corporation Law
of the State of  Delaware,  we,  Junaid  Sheikh  and  William  W.  Ericson,  the
President  and the  Secretary,  respectively,  of  Accom,  Inc.,  a  corporation
organized  and  existing  under  the  General  Corporation  Law of the  State of
Delaware DO HEREBY CERTIFY:

         That pursuant to the authority conferred upon the Board of Directors by
the Amended and Restated  Certificate of Incorporation of the said  Corporation,
the said Board of Directors, on September 3, 1996, and effective as of September
3,  1996,  adopted  the  following  resolution  creating  a series  of shares of
Preferred Stock designated as Series A Participating Preferred Stock:

         "RESOLVED,  that  pursuant  to the  authority  vested  in the  Board of
Directors  of the  corporation  by  the  Amended  and  Restated  Certificate  of
Incorporation,  the Board of  Directors  does hereby  provide for the issue of a
series  of  Preferred  Shares,  $0.001  par  value,  of the  Corporation,  to be
designated  "Series A Participating  Preferred Stock",  initially  consisting of
Sixty Thousand (60,000) shares and to the extent that the designations,  powers,
preferences  and  relative  and other  special  rights  and the  qualifications,
limitations and  restrictions of the Series A Participating  Preferred Stock are
not  stated  and   expressed  in  the  Amended  and  Restated   Certificate   of
Incorporation,  does hereby fix and herein state and express such  designations,
powers,   preferences   and   relative   and  other   special   rights  and  the
qualifications, limitations and restrictions thereof, as follows (all terms used
herein   which  are  defined  in  the  Amended  and  Restated   Certificate   of
Incorporation shall be deemed to have the meanings provided therein):

         Section 1.  Designation and Amount.  The shares of such series shall be
designated as "Series A  Participating  Preferred  Stock",  par value $0.001 per
share, and the number of shares constituting such series shall be Sixty Thousand
(60,000).

         Section 2. Dividends and Distributions.

                  (A) Subject to the prior and superior  right of the holders of
any shares of any series of Preferred  Stock  ranking  prior and superior to the
shares of Series A Participating Preferred Stock with respect to dividends,  the
holders of shares of Series A Participating Preferred Stock shall be entitled to
receive  when, as and if declared by the Board of Directors out of funds legally
available for the purpose,  quarterly  dividends payable in cash on the last day
of  December,  March,  June and  September  in each year  (each  such date being
referred to herein as a "Quarterly  Dividend  Payment Date"),  commencing on the
first  Quarterly  Dividend  Payment 



                                      -2-
<PAGE>

Date  after the first  issuance  of a share or  fraction  of a share of Series A
Participating  Preferred  Stock,  in an amount per share (rounded to the nearest
cent) equal to, subject to the provision for adjustment  hereinafter  set forth,
1,000 times the  aggregate  per share  amount of all cash  dividends,  and 1,000
times the aggregate per share amount (payable in kind) of all non-cash dividends
or other  distributions  other than a dividend payable in shares of Common Stock
or a subdivision of the outstanding shares of Common Stock (by  reclassification
or  otherwise),  declared on the Common  Stock of the  Corporation  (the "Common
Stock") since the immediately  preceding  Quarterly  Dividend  Payment Date, or,
with  respect to the first  Quarterly  Dividend  Payment  Date,  since the first
issuance of any share or fraction of a share of Series A Participating Preferred
Stock.  In the event the  Corporation  shall at any time after September 3, 1996
(the "Rights Declaration Date") (i) declare any dividend on Common Stock payable
in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii)
combine the  outstanding  Common Stock into a smaller number of shares,  then in
each such case the amount to which  holders of shares of Series A  Participating
Preferred  Stock  were  entitled  immediately  prior  to such  event  under  the
preceding  sentence shall be adjusted by multiplying  such amount by a fraction,
the  numerator  of which is the  number of shares  of Common  Stock  outstanding
immediately  after  such  event and the  denominator  of which is the  number of
shares of Common Stock that were outstanding immediately prior to such event.

                  (B) The  Corporation  shall declare a dividend or distribution
on the Series A Participating Preferred Stock as provided in paragraph (A) above
immediately  after it declares a dividend or  distribution  on the Common  Stock
(other than a dividend payable in shares of Common Stock).

                  (C)  Dividends  shall  begin to accrue  and be  cumulative  on
outstanding shares of Series A Participating  Preferred Stock from the Quarterly
Dividend  Payment Date next preceding the date of issue of such shares of Series
A  Participating  Preferred  Stock,  unless the date of issue of such  shares is
prior to the record date for the first Quarterly Dividend Payment Date, in which
case  dividends  on such shares  shall begin to accrue from the date of issue of
such shares, or unless the date of issue is a Quarterly Dividend Payment Date or
is a date after the record  date for the  determination  of holders of shares of
Series A Participating  Preferred Stock entitled to receive a quarterly dividend
and before such Quarterly  Dividend Payment Date, in either of which events such
dividends shall begin to accrue and be cumulative  from such Quarterly  Dividend
Payment Date.  Accrued but unpaid  dividends shall not bear interest.  Dividends
paid on the shares of Series A  Participating  Preferred Stock in an amount less
than the total amount of such  dividends at the time accrued and payable on such
shares  shall be  allocated  pro rata on a  share-by-share  basis among all such
shares at the time outstanding. The Board of Directors may fix a record date for
the determination of holders of shares of Series A Participating Preferred Stock
entitled to receive  payment of a dividend  or  distribution  declared  thereon,
which  record date shall be no more than 30 days prior to the date fixed for the
payment thereof.

         Section  3.  Voting   Rights.   The  holders  of  shares  of  Series  A
Participating Preferred Stock shall have the following voting rights:

                  (A) Subject to the provision for  adjustment  hereinafter  set
forth,  each share of Series A  Participating  Preferred Stock shall entitle the
holder  thereof  to  1,000  votes  on all  matters



                                      -3-
<PAGE>

submitted to a vote of the  stockholders  of the  Corporation.  In the event the
Corporation shall at any time after the Rights  Declaration Date (i) declare any
dividend on Common Stock payable in shares of Common Stock,  (ii)  subdivide the
outstanding  Common Stock, or (iii) combine the outstanding  Common Stock into a
smaller  number of shares,  then in each such case the number of votes per share
to which  holders  of shares  of Series A  Participating  Preferred  Stock  were
entitled  immediately  prior to such event shall be adjusted by multiplying such
number by a fraction,  the  numerator of which is the number of shares of Common
Stock  outstanding  immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding  immediately prior to
such event.

                  (B) Except as otherwise provided herein or by law, the holders
of shares of Series A Participating Preferred Stock and the holders of shares of
Common Stock shall vote together as one class on all matters submitted to a vote
of stockholders of the Corporation.

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

         Section 4. Certain Restrictions.

                  (A) The  Corporation  shall not declare any  dividend on, make
any   distribution   on,  or  redeem  or  purchase  or  otherwise   acquire  for
consideration  any shares of Common Stock after the first issuance of a share or
fraction  of  a  share  of  Series  A   Participating   Preferred  Stock  unless
concurrently therewith it shall declare a dividend on the Series A Participating
Preferred Stock as required by Section 2 hereof.

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

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

                           (ii)  declare  or pay  dividends  on,  make any other
distributions on any shares of stock ranking on a parity (either as to dividends
or upon  liquidation,  dissolution  or winding up) with  Series A  Participating
Preferred  Stock,  except  dividends paid ratably on the Series A  Participating
Preferred  Stock and all such parity stock on which  dividends are payable or in
arrears in  proportion  to the total  amounts  to which the  holders of all such
shares are then entitled;


                                      -4-
<PAGE>

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

                           (iv) purchase or otherwise  acquire for consideration
any shares of Series A  Participating  Preferred  Stock,  or any shares of stock
ranking on a parity with the Series A Participating  Preferred Stock,  except in
accordance  with  a  purchase  offer  made  in  writing  or by  publication  (as
determined  by the Board of  Directors)  to all holders of such shares upon such
terms as the Board of Directors,  after  consideration of the respective  annual
dividend  rates and other  relative  rights and  preferences  of the  respective
series and  classes,  shall  determine  in good  faith  will  result in fair and
equitable treatment among the respective series or classes.

                  (C) The  Corporation  shall not permit any  subsidiary  of the
Corporation  to purchase or otherwise  acquire for  consideration  any shares of
stock of the Corporation  unless the Corporation  could,  under paragraph (A) of
this Section 4,  purchase or  otherwise  acquire such shares at such time and in
such manner.

         Section 5.  Reacquired  Shares.  Any  shares of Series A  Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled promptly after the acquisition thereof.
All such shares shall upon their  cancellation  become  authorized  but unissued
shares  of  Preferred  Stock  and may be  reissued  as part of a new  series  of
Preferred  Stock to be  created by  resolution  or  resolutions  of the Board of
Directors,  subject to the  conditions  and  restrictions  on issuance set forth
herein.

         Section 6. Liquidation, Dissolution or Winding Up.

                  (A) Upon any liquidation (voluntary or otherwise), dissolution
or winding up of the Corporation,  no distribution  shall be made to the holders
of shares of stock ranking junior  (either as to dividends or upon  liquidation,
dissolution or winding up) to the Series A Participating Preferred Stock unless,
prior thereto,  the holders of shares of Series A Participating  Preferred Stock
shall  have  received  an amount  equal to  accrued  and  unpaid  dividends  and
distributions  thereon,  whether or not  declared,  to the date of such payment,
plus an amount  equal to the greater of (1) $1,000 per share,  provided  that in
the event the Corporation does not have sufficient assets,  after payment of its
liabilities and  distribution to holders of Preferred Stock ranking prior to the
Series A Participating  Preferred Stock,  available to permit payment in full of
the $1,000 per share amount,  the amount  required to be paid under this Section
6(A)(1) shall,  subject to Section 6(B) hereof, equal the value of the amount of
available  assets  divided  by the  number  of  outstanding  shares  of Series A
Participating  Preferred  Stock or (2) subject to the  provisions for adjustment
hereinafter  set  forth,  1,000  times  the  aggregate  per  share  amount to be
distributed  to the  holders  of Common  Stock (the  greater of (1) or (2),  the
"Series A Liquidation  Preference").  In the event the Corporation  shall at any
time after the Rights  Declaration Date (i) declare any dividend on Common Stock
payable in shares of Common Stock, (ii) subdivide the outstanding  Common Stock,
or (iii) combine the  outstanding  Common Stock into a smaller 



                                      -5-
<PAGE>

number of shares,  then in each such case the amount to which  holders of shares
of Series A  Participating  Preferred Stock were entitled  immediately  prior to
such event  under  clause (2) of the  preceding  sentence  shall be  adjusted by
multiplying  such amount by a fraction  the  numerator of which is the number of
shares of Common Stock that were  outstanding  immediately  after such event and
the  denominator  of which is the  number of shares  of Common  Stock  that were
outstanding immediately prior to such event.

                  (B) In the  event,  however,  that  there  are not  sufficient
assets  available  to  permit  payment  in  full  of the  Series  A  Liquidation
Preference  and the  liquidation  preferences  of all other  series of Preferred
Stock, if any, which rank on a parity with the Series A Participating  Preferred
Stock, then such remaining assets shall be distributed ratably to the holders of
such parity shares in proportion to their respective liquidation preferences.

         Section 7.  Consolidation,  Merger,  etc. In case the Corporation shall
enter into any consolidation,  merger, combination or other transaction in which
the shares of Common  Stock are  exchanged  for or changed  into other  stock or
securities,  cash and/or any other property, then in any such case the shares of
Series A  Participating  Preferred  Stock  shall at the same  time be  similarly
exchanged  or changed  in an amount  per share  (subject  to the  provision  for
adjustment  hereinafter set forth) equal to 1,000 times the aggregate  amount of
stock, securities, cash and/or any other property (payable in kind), as the case
may be,  into  which or for which  each  share of  Common  Stock is  changed  or
exchanged.  In the  event the  Corporation  shall at any time  after the  Rights
Declaration  Date (i) declare any dividend on Common Stock  payable in shares of
Common Stock, (ii) subdivide the outstanding  Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the amount set forth in the  preceding  sentence with respect to the exchange or
change of shares of Series A Participating  Preferred Stock shall be adjusted by
multiplying  such amount by a fraction  the  numerator of which is the number of
shares  of  Common  Stock  outstanding  immediately  after  such  event  and the
denominator  of  which is the  number  of  shares  of  common  Stock  that  were
outstanding immediately prior to such event.

         Section  8.  No  Redemption.  The  shares  of  Series  A  Participating
Preferred Stock shall not be redeemable.

         Section 9. Ranking.  The Series A  Participating  Preferred Stock shall
rank junior to all other series of the  Corporation's  Preferred Stock as to the
payment of dividends  and the  distribution  of assets,  unless the terms of any
such series shall provide otherwise.

         Section  10.  Amendment.   The  Certificate  of  Incorporation  of  the
Corporation  shall not be further  amended in any manner which would  materially
alter or change  the  powers,  preference  or  special  rights  of the  Series A
Participating  Preferred  Stock  so as to  affect  them  adversely  without  the
affirmative vote of the holders of a majority or more of the outstanding  shares
of Series A Participating Preferred Stock, voting separately as a class.

         Section 11. Fractional Shares.  Series A Participating  Preferred Stock
may be issued in  fractions  of a share  which  shall  entitle  the  holder,  in
proportion  to such  holder's  fractional  shares,  



                                      -6-

Preferred Stock."

                                Summary of Rights

Distribution and               The Board of Directors has declared a dividend of
Transfer of Rights;            one  Right  for  each  share of  Common  Stock of
Rights Certificate:            Accom, Inc. (the "Company") outstanding. Prior to
                               the  Distribution  Date  referred  to below,  the
                               Rights  will be  evidenced  by and trade with the
                               certificates  for the  Common  Stock.  After  the
                               Distribution  Date,  the Company will mail Rights
                               certificates  to the Company's  stockholders  and
                               the Rights  will become  transferable  apart from
                               the Common Stock.                                

Distribution Date:             Rights will  separate  from the Common  Stock and
                               become  exercisable  following  the tenth day (or
                               such  later  date  as  may  be  determined  by  a

                               affiliated  with the  acquiring  person  or group
                               (the "Continuing  Directors"))  after a person or
                               group (a) acquires beneficial ownership of 15% or
                               more  of  the  Company's   Common  Stock  or  (b)

                               consummation  of which would  result in ownership
                               by a  person  or  group  of  15% or  more  of the
                               Company's Common Stock (the "Distribution Date").

Preferred Stock                After the  Distribution  Date,  each  Right  will
Purchasable Upon               entitle  the  holder  to  purchase,  for  $20,  a

Amendment of Terms             The terms of the Rights and the Rights  Agreement
of Rights:                     may be amended in any respect without the consent
                               of  the  Rights   holders  on  or  prior  to  the
                               Distribution Date;  thereafter,  the terms of the
                               Rights  and the Rights  Agreement  may be amended
                               without  the  consent  of the  Rights  holders in
                               order to cure any  ambiguities or to make changes
                               which do not  adversely  affect the  interests of
                               Rights holders (other than the Acquiring Person).

Voting Rights:                 Rights will not have any voting rights.

Anti-Dilution                  Rights will have the benefit of certain customary
Provisions:                    anti-dilution provisions.

Taxes:                         The Rights distribution should not be taxable for
                               federal income tax purposes.  However,  following
                               an event which renders the Rights  exercisable or
                               upon redemption of the Rights,  stockholders  may
                               recognize taxable income.                        

The foregoing is a summary of certain principal terms of the Stockholder  Rights
Plan only and is qualified in its entirety by reference to the detailed terms of
the Rights Agreement dated as of September 13, 1996, between the Company and the
Rights Agent.
