OFFICER'S INDEMNIFICATION AGREEMENT

THIS  AGREEMENT  is made and entered  into as of June 29,  1999,  by and between
MODIS PROFESSIONAL  SERVICES,  INC., a Florida corporation (the  "Corporation"),
and __________________ (the "Indemnitee").

WHEREAS, the Indemnitee is a member of the Board of Directors of the Corporation
and in such capacity is performing a valuable service to the Corporation; and

WHEREAS, Section 607.0850 of the Florida Business Corporation Act, as amended to
date (the "State  Statute")  specifically  contemplates  that  contracts  may be
entered into between the  Corporation and members of its Board of Directors with
respect to indemnification of such officers and directors; and

WHEREAS,  in order to provide to the Indemnitee  assurances  with respect to the
protection  provided against liabilities that he may incur in the performance of
his duties to the Corporation,  and to thereby induce the Indemnitee to continue
to serve as a member of its Board of Directors,  the  Corporation has determined
and agreed to enter into this Agreement with the Indemnitee;

NOW, THEREFORE,  in consideration of the premises and the Indemnitee's continued
service  or a  director  after  the date  hereof,  and other  good and  valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties agree as follows:

1.  Indemnification.  Subject  only to the  exclusions  set  forth in  Section 2
hereof,  and in addition to any other  indemnity to which the  Indemnitee may be
entitled  under the State Statute or any bylaw,  resolution,  or agreement  (but
without  duplication  of payments  with  respect to  indemnified  amounts),  the
Corporation  hereby agrees to hold harmless and indemnify the  Indemnitee to the
full extent that the State Statute,  or any amendment thereof or other statutory
provision adopted after the date hereof, authorizes,  including, but not limited
to,  holding  harmless  and  indemnifying  the  Indemnitee  against  any and all
expenses  (including  attorneys,  fees),  judgments,  fines and amounts  paid in
settlement actually and reasonably incurred by the Indemnitee in connection with
any  threatened,  pending,  or completed  action,  suit, or proceeding,  whether
civil, criminal,  administrative, or investigative (including an action by or in
the right of the  Corporation),  to which the Indemnitee is, was, or at any time
becomes a party, or is threatened to be made a party, by reason of the fact that
the Indemnitee is, was, or at any time becomes a director,  officer, employee or
agent of the  Corporation  or any  subsidiary of the  Corporation,  or is or was
serving or at any time serves at the request of the  Corporation  as a director,
officer, employee, or agent of another corporation,  partnership, joint venture,
trust, or other enterprise.  The indemnification hereunder shall be broader than
that provided for in the Articles of Incorporation  and Bylaws,  and in addition
to any rights granted thereunder.

2.  Limitations on Indemnity.  Indemnification  or advancement of expenses shall
not be made to or on behalf of the Indemnitee:

(a) If a judgment or other final adjudication  establishes that his actions,  or
omissions  to act,  were  material  to the cause of action  so  adjudicated  and
constitute:

(i) a violation of the criminal law, unless the Indemnitee had reasonable  cause
to believe  his  conduct  was lawful or had no  reasonable  cause to believe his
conduct was unlawful;

(ii) a  transaction  from  which the  Indemnitee  derived an  improper  personal
benefit;

(iii) a circumstance under which the liability provisions of Section 607.0834 of
the State Statute are applicable to the Indemnitee; or

(iv) willful  misconduct or a conscious  disregard for the best interests of the
Corporation  in a proceeding by or in the right of the  Corporation to procure a
judgment in its favor or in a proceeding by or in the right of a shareholder.

(b) With  respect to any suit in which final  judgment  is rendered  against the
Indemnitee  for an  accounting  of profits made from the purchase or sale by the
Indemnitee  of  securities  of the  Corporation,  pursuant to the  provisions of
Section 16(b) of the  Securities  Exchange Act of 1934 or similar  provisions of
any federal,  state, or local statutory law, or on account of any payment by the
Indemnitee to the Corporation in respect of any claim for such an accounting.

(c) If a final  decision  by a court  having  jurisdiction  in the matter  shall
determine that such indemnification is not lawful.

3.  Contribution.  If the  indemnification  provided for in Section 1 thereof is
unavailable  and may not be paid to the  Indemnitee  for any  reason  other than
those set forth in Section  2(b)  hereof,  then in  respect  of any  threatened,
pending,  or completed  action,  suit, or proceeding in which the Corporation is
jointly liable with the  Indemnitee (or would be if joined in such action,  suit
or  proceeding),  the  Corporation  shall  contribute,  to the  extent it is not
prohibited  from  doing so, to the  amount of  expenses  judgments,  fines,  and
settlements  paid  or  payable  by  the  Indemnitee  in  such  proportion  as is
appropriate to reflect (a) the relative  benefits received by the Corporation on
the one hand and the  Indemnitee  on the other  hand from the  transaction  from
which such action,  suit, or proceeding arose, and (b) the relative fault of the
Corporation  on the one hand and of the  Indemnitee  on the other in  connection
with the events which resulted in such expenses, judgments, fines, or settlement
amounts,  as well as any other relevant equitable  considerations.  The relative
fault of the  corporation  on the one hand and of the  Indemnitee  on the  other
shall be determined by reference to, among other things,  the parties,  relative
intent, knowledge, access to information,  and opportunity to correct or prevent
the circumstances  resulting in such expenses,  judgments,  fines, or settlement
amounts.  The  Corporation  agrees  that it would not be just and  equitable  if
contribution  pursuant to this Section 3 were  determined by pro rata allocation
or any other method of  allocation  that does not take account of the  foregoing
equitable considerations.

4.   Continuation  of  Obligations.   All  agreements  and  obligations  of  the
Corporation  contained herein shall continue during the period the Indemnitee is
a director, officer, employee, or agent of the Corporation (or is serving at the
request of the corporation as a director, officer, employee, or agent of another
corporation,  partnership,  joint venture, trust, or other enterprise) and shall
continue  thereafter  for so long as the  Indemnitee  shall  be  subject  to any
possible claim or threatened, pending, or completed action, suit, or proceeding,
whether  civil,  criminal,  or  investigative,  by  reason  of the fact that the
Indemnitee  was an officer or a director  of the  Corporation  or serving in any
other capacity referred to herein.

5. Notification and Defense of Claim.

(a) Promptly  after receipt by the Indemnitee of notice of the  commencement  of
any action,  suit, or  proceeding,  the  Indemnitee  will, if a claim in respect
thereof is to be made against the Corporation  under this Agreement,  notify the
Corporation  of the  commencement  thereof,  but the  omission  to so notify the
Corporation  will not relieve the  Corporation  from any liability  which it may
have to the Indemnitee otherwise than under this Agreement.

(b) With  respect  to any such  action,  suit,  or  proceeding  as to which  the
Indemnitee so notifies the Corporation:

(i) the Corporation will be entitled to participate  therein at its own expense;
and

(ii) subject to Section 6 hereof,  and if the Indemnitee shall have provided his
written affirmation of his good faith belief that his conduct did not constitute
behavior of the kind described in Section 2(a) hereof and that he is entitled to
indemnification hereunder, the Corporation may assume the defense thereof.

After notice from the Corporation to the Indemnitee of its election so to assume
such defense,  the corporation  will not be liable to the Indemnitee  under this
Agreement  for  any  legal  or  other  expenses  subsequently  incurred  by  the
Indemnitee in connection with the defense  thereof,  other than reasonable costs
of investigation  or as otherwise  provided below. The Indemnitee shall have the
right to employ its separate  counsel in such action,  suit, or proceeding,  but
the fees and expenses of such counsel incurred after notice from the Corporation
of its  assumption  of the  defense  thereof  shall  be at  the  expense  of the
Indemnitee  unless (iii) the  employment of counsel by the  Indemnitee  has been
authorized by the  Corporation,  (v) counsel  designated by the  Corporation  to
conduct such defense shall not be reasonably satisfactory to the Indemnitee,  or
(v) the  Corporation  shall  not in fact have  employed  counsel  to assume  the
defense of such  action,  in each of which  cases the fees and  expenses of such
counsel shall be at the expense of the  Corporation.  For the purposes of clause
(v) above, the Indemnitee shall be entitled to determine that counsel designated
by the Corporation is not reasonably  satisfactory if, among other reasons,  the
Indemnitee shall have been advised by qualified counsel that,  because of actual
or potential  conflicts of interest in the matter between the Indemnitee,  other
officers or  directors  similarly  indemnified  by the  Corporation,  and/or the
Corporation,  representation  of the  Indemnitee  by counsel  designated  by the
Corporation  is likely to  materially  and  adversely  affect  the  Indemnitee's
interest or would not be permissible under applicable canons of legal ethics.

(c) The Corporation  shall not be liable to indemnify the Indemnitee  under this
Agreement  for any amounts paid in  settlement  of any action or claim  effected
without the Corporation's  written consent. The Corporation shall not settle any
action or claim in any manner  which would impose any penalty or  limitation  on
the  Indemnitee   without  the  Indemnitee  Is  written  consent.   Neither  the
Corporation  nor  the  Indemnitee  will  unreasonably  withhold  consent  to any
proposed settlement.

6. Advancement and Repayment of Expenses.  Upon request therefor  accompanied by
reasonably  itemized  evidence of  expenses  incurred,  and by the  Indemnitee's
written  affirmation  of his good faith belief that his conduct met the standard
applicable  to  indemnification  pursuant  to  Section  1  hereof  and  did  not
constitute behavior of the kind described in Section 2(a) hereof, and that he is
entitled to  indemnification  hereunder,  the  Corporation  shall advance to the
Indemnitee  the  reasonable  expenses  (including  attorneys'  fees and costs of
investigation  and  defense  (including  the  fees of  expert  witnesses,  other
professional advisors, and private investigators))  incurred by him in defending
any civil or criminal  suit,  action,  or proceeding for which the Indemnitee is
entitled (assuming an applicable  standard of conduct is met) to indemnification
pursuant to this Agreement. In the alternative and in the Indemnitee's exclusive
discretion, the Corporation will assume direct responsibility for the payment of
all such  expenses  after the  Indemnitee  has provided the  Corporation  with a
written  request to assume direct  responsibility  for such payment and after he
has complied with the affirmation  requirements  provided above.  The Indemnitee
agrees to reimburse  the  Corporation  for all  reasonable  expenses paid by the
Corporation,  whether pursuant to this Section or Section 5 hereof, in defending
any action,  suit, or proceeding  against the Indemnitee in the event and to the
extent  that it  shall  ultimately  be  determined  that the  Indemnitee  is not
entitled to be  indemnified  by the  Corporation  for such  expenses  under this
Agreement.  Any  advances  and the  Indemnitee's  agreement  to  repay  shall be
unsecured and interest-free.

7. Agreement to Serve.  The  Indemnitee  hereby agrees to continue to serve as a
director of the Corporation faithfully and to the best of his ability so long as
he is duly elected and qualified in accordance with the provisions of the Bylaws
or until such time as he tenders his resignation in writing.

8.      Enforcement.

(a) The Corporation  expressly confirms and agrees that it has entered into this
Agreement  and assumed the  obligations  imposed on it hereby in order to induce
the  Indemnitee  to serve as an  officer or a director  of the  Corporation  and
acknowledges  that the  Indemnitee  will in the  future  be  relying  upon  this
Agreement in continuing to serve in such capacity.

(b) If the  Indemnitee  is required to bring any action to enforce  rights or to
collect  moneys due under this  Agreement and is successful in such action,  the
Corporation   shall  reimburse  the  Indemnitee  for  all  of  the  Indemnitee's
reasonable fees and expenses in bringing and pursuing such action.

9.  Separability.  Each of the  provisions  of this  Agreement is a separate and
distinct  agreement  and  independent  of the others,  so that if any  provision
hereof shall be held to be invalid or  unenforceable in whole or in part for any
reason,  such  invalidity or  unenforceability  shall not affect the validity or
enforceability of the other provisions hereof.

10.     Governing Law; Successors; Amendment and Termination.

(a) This Agreement shall be interpreted and enforced in accordance with the laws
of the State of Florida.

(b) This Agreement  shall be binding upon the Indemnitee and the Corporation and
its successors and assigns (including any transferee of all or substantially all
of its assets and any successor by merger or otherwise by operation of law), and
shall   inure  to  the   benefit  of  the   Indemnitee,   his  heirs,   personal
representatives,  and  assigns  and to the  benefit of the  Corporation  and its
successors and assigns.

(c) No amendment,  modification,  termination, or cancellation of this Agreement
shall be effective unless in writing signed by both parties hereto.

11. Counterparts.  This Agreement may be executed in counterparts, each of which
shall be deemed an original but all of which shall  constitute  one and the same
instrument.

12.  Notices.  All  notices,  requests  and  other  communications  required  or
permitted  hereunder  shall be in writing  and shall be deemed to have been duly
given and  received  when  delivered  in person,  when  delivered  by  overnight
delivery  service,  or three  business  days after being mailed by registered or
certified mail,  postage  prepaid,  return receipt  requested,  to the following

             Rights  Agreement,  dated  as of  September  19,  1991  (the
  "Agreement"),   between   Carrington  Laboratories,   Inc.,   a   Texas
  corporation   (the   "company"),  and   Ameritrust   Company   National
  Association (the "Rights Agent").

             The  Board of Directors  of the Company  has authorized  and
  declared a dividend of  one preferred share purchase right (a  "Right")
  for  each  Common  Share  (as  hereinafter  defined)  of  the   Company
  outstanding  on  October  15, 1991  (the  "Record  Date"),  each  Right
  representing  the right to  purchase one one-hundredth  of a  Preferred
  Share  (as hereinafter  defined), upon  the terms  and subject  to  the
  conditions herein  set forth, and has  further authorized and  directed
  the issuance of one Right with respect to each Common Share that  shall
  become  outstanding between the  Record Date  and the  earliest of  the
  Distribution Date,  the Redemption Date and  the Final Expiration  Date
  (as such terms are hereinafter defined).

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

  Agreement, the following terms have the meanings indicated:

       term  is hereinafter  defined)  who or  which, together  with  all

       hereinafter defined)  of 20% or more of  the Common Shares of  the
       Company then outstanding,  but shall not include the Company,  any
       Subsidiary (as such  term is hereinafter defined) of the  Company,
       any employee benefit plan of the Company or 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 become an  "Acquiring Person"  as the  result of  an
       acquisition  of Common Shares  by the Company  which, by  reducing
       the  number of  shares  outstanding, increases  the  proportionate
       number of shares beneficially owned by such Person to 20% or  more
       of the  Common Shares of the  Company then outstanding;  provided,
       however,  that if a  Person shall become  the Beneficial Owner  of
       20% 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".

  herein referred to as the "Distribution Date"), (x) the Rights will  be
  evidenced  (subject to the  provisions of Section  3(b) hereof) by  the
  certificates for Common Shares  registered in the names of the  holders
  thereof  (which  certificates   shall  also  be  deemed  to  be   Right
  Certificates)  and not  by  separate Right  Certificates, and  (y)  the
  right  to  receive Right  Certificates  will be  transferable  only  in
  connection with the transfer  of Common Shares. As soon as  practicable
  after the Distribution Date, the Company will prepare and execute,  the
  Rights Agent  will countersign, and the Company  will send or cause  to
  be  sent (and  the Rights  Agent will,  if requested,  send) by  first-
  class, postage-prepaid mail, to each record holder of Common Shares  as
  of the  close of business on the Distribution  Date, at the address  of
  such holder shown on  the records of the Company, a Right  Certificate,
  in substantially the form of Exhibit B hereto (a "Right  Certificate"),
  evidencing  one  Right  for  each Common  Share  so  held,  As  of  the
  Distribution Date,  the Rights will be  evidenced solely by such  Right

  thereafter,  the Company will  send a copy  of a Summary  of Rights  to
  Purchase  Preferred Shares,  in  substantially the  form of  Exhibit  C
  hereto  (the  "Summary of  Rights"),  by  first-class,  postage-prepaid
  mail,  to each  record  holder of  Common Shares  as  of the  close  of
  business on  the Record Date, at  the address of  such holder shown  on
  the  records of the  Company. With respect  to certificates for  Common
  Shares outstanding as of the Record Date, until the Distribution  Date,
  the  Rights will be  evidenced by such  certificates registered in  the
  names  of the  holders thereof.  Until the  Distribution Date  (or  the
  earlier  of the  Redemption Date  or the  Final Expiration  Date),  the
  surrender   for  transfer  of   any  certificate   for  Common   Shares
  outstanding on  the Record Date shall  also constitute the transfer  of
  the Rights associated with the Common Shares represented thereby.

              (c)  Certificates   for   Common   Shares   which    become
  outstanding  (including, without limitation,  reacquired Common  Shares

  certificate- Carrington Laboratories,  Inc. will mall to the holder  of
  this  certificate a eon  of the Rights  Agreement without charge  after
  receipt  of  a written  request  therefor  at the  principal  place  of

  becomes an  Acquiring Person (as defined  in the Rights Agreement)  may
  become null and void,

              With respect to such certificates containing the  foregoing
  legend,  until the Distribution  Date, the Rights  associated with  the
  Common Shares  represented by such certificates  shall be evidenced  by
  such  certificates alone, and  the surrender for  transfer of any  such
  certificate  shall   also  constitute  the   transfer  of  the   Rights
  associated  with the Common  Shares represented thereby.  In the  event
  that  the Company purchases  or acquires  any Common  Shares after  the
  Record Date but prior  to the Distribution Date, any Rights  associated
  with such  Common Shares shall be deemed  canceled and retired so  that
  the  Company shall not  be entitled to  exercise any Rights  associated
  with the Common Shares which are no longer outstanding,

  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

  Section  22 hereof, the  Right Certificates shall  entitle the  holders
  thereof to  purchase such number of  one one-hundredths of a  Preferred
  Share as shall be set forth therein at the price per one  one-hundredth
  of a Preferred Share set forth therein (the "Purchase Price"), but  the
  number  of  such  one  one-hundredths of  a  Preferred  Share  and  the

  same  force and  effect as  though  the person  who signed  such  Right
  Certificates had not ceased to be such officer of the Company; and  any
  Right Certificate may be signed on behalf of the Company by any  person
  who, at  the actual date  of the execution  of such Right  Certificate,

  Certificate,  although at  the date  of the  execution of  this  Rights
  Agreement any such person was not such an officer,

  certificate  of cancellation  thereof, as  may be  appropriate, to  the
  Company.

              Section 9. Reservation and Availability of Capital Stock.

              (a)  The Company covenants  and agrees that  it will  cause
  to be  reserved and kept available out  of its authorized and  unissued
  Preferred Shares (and, following the occurrence of a Triggering  Event,
  out  of  its  authorized  and  unissued  Common  Shares  and/or   other
  securities  or out  of its  authorized and  issued shares  held in  its
  treasury),  the   number  of  Preferred   Shares  (and  following   the
  occurrence  of   a  Triggering  Event,   Common  Shares  and/or   other
  securities)  that,  as provided  in  this Agreement  including  Section
  11(a)(iii) hereof,  will be sufficient to  permit the exercise in  full
  of all outstanding Rights.
<PAGE>
              (b)  So long as  the Preferred Shares  (and, following  the
  occurrence  of a  Triggering Event,  Common Shares  and/or  securities)
  issuable and deliverable upon the exercise of the Rights may be  listed
  on any  national securities exchange  or inter-dealer quotation  system
  of a registered national securities association on which the  Preferred
  Shares may from time  to time be listed, traded or quoted, the  Company
  shall use reasonable efforts to cause, from and after such time as  the
  Rights become exercisable, all shares reserved for such issuance to  be
  listed  on such exchange  or quotation system  upon official notice  of
  issuance upon such exercise.

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

              Section 10. Preferred  Shares Record Date.  Each person  in
  whose  name any  certificate  for Preferred  Shares (or  Common  Shares
  and/or  other  securities, as  the  case may  be)  is issued  upon  the
  exercise of Rights shall for all purposes be deemed to have become  the
  holder  of record  of the  Preferred Shares  (or Common  Shares  and/or
  other securities, as the case may be) represented thereby on, and  such
  certificate shall be dated,  the date upon which the Right  Certificate
  evidencing  such  Rights  was  duly  surrendered  and  payment  of  the
  Purchase Price (and any applicable transfer taxes) was made,  provided,
  however that if the  date of such surrender and payment is a date  upon
  which the Preferred  Shares (or Common Shares and/or other  securities,
  as  the case may  be) 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  (or  Common Shares  and/or  other
  securities,  as the  case may  be) transfer  books of  the Company  are
  open.  Prior to  the  exercise of  the  Rights evidenced  thereby,  the
  holder of a Right Certificate shall not be entitled to any rights of  a
  shareholder of Preferred Shares  of the Company with respect to  shares
  for  which   the  Rights  shall  be  exercisable,  including,   without
  limitation,  the  right   to  vote,  to  receive  dividends  or   other
  distributions or  to exercise any preemptive  rights, and shall not  be
  entitled  to receive  any notice  of any  proceedings of  the  Company,
  except as provided herein.

              Section II, Adjustment of  Purchase Price. Number and  Kind
  of Shares or Number of Rights. The Purchase Price, the number and  kind
  of shares  covered by each Right and  the number of Rights  outstanding
  are  subject  to adjustment  from  time to  time  as provided  in  this
  section 11.
<PAGE>
              (a)  (i) In the event the  Company shall at any time  after
  the  date of this  Agreement (A) declare  a dividend  on the  Preferred
  Shares  payable  in Preferred  Shares,  (B) subdivide  the  outstanding
  Preferred Shares, (C)  combine the outstanding Preferred Shares into  a
  smaller  number of Preferred  Shares, or (D)  issue any  shares of  its
  capital stock in a reclassification of the Preferred Shares  (including
  any such reclassification in connection with a consolidation or  merger
  in  which the  Company  is the  continuing or  surviving  corporation),
  except  as  otherwise  provided  in  this  Section  11(a)  hereof,  the
  Purchase  Price in  effect at  the time  of the  record date  for  such
  dividend or of the  effective date of such subdivision, combination  or
  reclassification, and  the number and kind  of shares of capital  stock
  issuable on  such date, shall be  proportionately adjusted so that  the
  holder  of any Right  exercised after such  time shall  be entitled  to
  receive,  upon  payment of  the  Purchase  Price then  in  effect,  the
  aggregate  number and kind  of Preferred  Shares or  shares of  capital
  stock  which, if such  right had  been exercised  immediately prior  to
  such date  and at a time  when the Preferred  Shares transfer books  of
  the Company were open, he would have owned upon such exercise and  been
  entitled  to   receive  by  virtue   of  such  dividend,   subdivision,
  combination  or  reclassification.  If  an  event  occurs  which  would
  require  an adjustment  under both  this Section  11(a)(i) and  Section
  11(a)(ii) hereof, the adjustment provided for in this Section  11(a)(i)
  shall be  in addition to, and  shall be made  prior to, any  adjustment
  required pursuant to Section 11(a)(ii)) hereof.

              (ii) (A) Subject to Sections 23 and  24 of this  Agreement,
  in  the  event  any  Person becomes  an  Acquiring  Person  other  than
  pursuant to a Flip-Over  Event at any time after September 19, 1991  (a
  "Flip-In Event"), each holder of a Right shall thereafter have a  right
  to receive, upon exercise thereof at a price equal to the then  current
  Purchase  Price multiplied by  the number  of one  one-hundredths of  a
  Preferred Share  for which a Right  is then exercisable, in  accordance
  with the terms of this Agreement and in lieu of Preferred Shares,  such
  number of  Common Shares of the Company  (such number of Common  Shares
  to  be referred to  hereinafter as  the "Adjustment  Shares") as  shall
  equal the result obtained by (x) multiplying the then current  Purchase
  Price  by the number  of one one-hundredths  of a  Preferred Share  for
  which a  Right is then  exercisable and dividing  that product by  (y))
  50% of the then current per share market price of the Company's  Common
  Shares  (determined pursuant to  Section 11(d) hereof)  on the date  of
  the  occurrence of  such event.  In  the event  that any  Person  shall
  become an  Acquiring Person and the  Rights shall then be  outstanding,
  the  Company  shall  not  take any  action  which  would  eliminate  or
  diminish the benefits intended to be afforded by the Rights.

                     (B) From and  after  the  occurrence  of  a  Flip-In
  Event, any Rights that  are or were acquired  or beneficially owned  by
  any Acquiring Person (or any Associate  or Affiliate of such  Acquiring
  Person) shall be void, and any  holder of such Rights shall  thereafter
  have no  right to  exercise such  Rights under  any provision  of  this
  Agreement. No Right Certificate shall be  issued pursuant to Section  3
  that represents Rights beneficially owned by an Acquiring Person  whose
  Rights would  be  void  pursuant  to  the  preceding  sentence  or  any
  Associate or Affiliate thereof; no Right Certificate shall be issued at
  any time upon the transfer of  any Rights to an Acquiring Person  whose
  Rights would  be  void  pursuant  to  the  preceding  sentence  or  any
<PAGE>
  Associate or  Affiliate thereof  or to  any nominee  of such  Acquiring
  Person, Associate or Affiliate; and any Right Certificate delivered  to
  the Rights Agent for transfer to an Acquiring Person whose Rights would
  be void pursuant to the preceding sentence shall be canceled.

               (iii) In the event that the number of Common Shares  which
  is authorized  by  the  Company's Articles  of  Incorporation  but  not
  outstanding or not reserved for issuance  for purposes other than  upon
  exercise of the Rights is not sufficient to permit the exercise in full
  of the Rights  in accordance with  the foregoing  subparagraph (ii)  of
  this Section  11(a), the  Company shall,  to  the extent  permitted  by
  applicable law  and regulation:  (A) determine  the excess  of (1)  the
  value of the Adjustment  Shares issuable upon the  exercise of a  Right
  (the "Current Value") over  (2) the Purchase Price  (such excess to  be
  referred to hereinafter as the "Spread"), and (B) with respect to  each
  Right, make adequate provision to substitute for the Adjustment Shares,
  upon payment  of  the  applicable  Purchase  Price,  (I)  cash,  (2)  a
  reduction in  the Purchase  Price, (3)  Common Shares  or other  equity
  securities of the  Company (including, without  limitation, shares,  or
  units of shares, of  preferred stock which the  Board of Directors  has
  deemed to have  the same  value as the  Common Shares  (such shares  of
  preferred stock, "common  share equivalents"), (4)  debt securities  of
  the Company. (5) other assets or (6) any combination of the  foregoing,
  having an  aggregate  value equal  to  the Current  Value,  where  such
  aggregate value has  been determined by  the Board  of Directors  based
  upon the advice of an investment banking firm selected by the Board  of
  Directors; provided,  however,  if  the Company  shall  not  have  made
  adequate provisions to deliver value pursuant  to clause  above  within
  30 days following the first occurrence of a Flip-In Event (the "Flip-in
  Trigger Date", then the Company shall be obligated to deliver, upon the
  surrender for exercise of a Right and without requiring payment of  the
  Purchase Price, Common Shares  (to the extent  available) and then,  if
  necessary, cash, which shares and/or cash have an aggregate value equal
  to the Spread. If the Board of Directors determines in good faith  that
  it  is  likely  that  sufficient  additional  Common  Shares  could  be
  authorized for issuance upon exercise in full of the Rights, the 30-day
  period set forth above may be extended to the extent necessary, but not
  more than 90  days after the  Flip-In Trigger Date,  in order that  the
  Company may seek  shareholder approval  for the  authorization of  such
  additional  shares  (such   period,  as   it  may   be  extended,   the
  "Substitution Period"). To the extent that the Company determines  that
  some action need be taken pursuant to the first and/or second sentences
  of this Section 11  (a)(iii), the Company (x)  shall provide that  such
  action shall apply  uniformly to all  outstanding Rights,  and (y)  may
  suspend the exercisability of  the Rights until  the expiration of  the
  Substitution Period in  order to seek  any authorization of  additional
  shares and/or to decide the appropriate form of distribution to be made
  pursuant to such first sentence and  to determine the value thereof  In
  the event of  any such  suspension, the  Company shall  issue a  public
  announcement stating that  the exercisability  of the  Rights has  been
  temporarily suspended, as well as a public announcement at such time as
  the suspension is  no longer in  effect. For purposes  of this  Section
  11(a)(iii), 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 Flip-In  Trigger Date, and  the value of  any
  common share equivalent shall be deemed  to have the same value as  the
  Common Shares on such date,
<PAGE>
                  (b)      In case the  Company shall fix  a record  date
  for the  issuance of  rights, options  or warrants  to all  holders  of
  Preferred Shares  entitling  them  (for a  period  expiring  within  45
  calendar days  after such  record date)  to subscribe  for or  purchase
  Preferred Shares  (or shares  having the  same rights,  privileges  and
  preferences as the Preferred Shares ("equivalent preferred shares")) or
  securities convertible into  Preferred Shares  or equivalent  preferred
  shares at a price per Preferred Share or equivalent preferred share (or
  having a conversion  price per share,  if a  security convertible  into
  Preferred Shares or  equivalent preferred  shares) less  than the  then
  current per share market price of  the Preferred Shares (as defined  in
  Section 11(d)) on such record date, the Purchase Price to be in  effect
  after such record date shall be determined by multiplying the  Purchase
  Price in effect immediately  prior to such record  date by a  fraction,
  the numerator  of  which  shall  be  the  number  of  Preferred  Shares
  outstanding on such  record date plus  the number  of Preferred  Shares
  which the aggregate  offering price of  the total  number of  Preferred
  Shares and/or equivalent preferred shares so to be offered (and/or  the
  aggregate initial conversion price of the convertible securities so  to
  be offered)  would  purchase  at such  current  market  price  and  the
  denominator  of  which  shall  be   the  number  of  Preferred   Shares
  outstanding on such record date plus the number of additional Preferred
  Shares  and/or   equivalent  preferred   shares  to   be  offered   for
  subscription or purchase (or into  which the convertible securities  so
  to be offered are initially convertible);  provided however that in  no
  event shall the consideration to be paid upon the exercise of one Right
  be less than the aggregate par value of the shares of capital stock  of
  the  Company  issuable  upon  exercise  of  one  Right.  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.  Preferred  Shares owned  by  or held  for  the
  account of the Company shall not be deemed outstanding for the  purpose
  of any such  computation. Such  adjustment shall  be made  successively
  whenever such  a record  date is  fixed;  and in  the event  that  such
  rights, options or warrants ate not so issued, the Purchase Price shall
  be adjusted to be the Purchase Price  which would then be in effect  if
  such record date had not been fixed.

            (c)    In case the Company  shall fix a  record date for  the
  making  of  a distribution  to  all  holders of  the  Preferred  Shares
  (including   any  such   distribution  made   in  connection   with   a
  consolidation  or merger  in which  the Company  is the  continuing  or
  surviving corporation)  of evidences of  indebtedness or assets  (other
  than  a  regular quarterly  cash  dividend  or a  dividend  payable  in
  Preferred Shares)  or subscription rights or warrants (excluding  those
  referred  to in  Section 11(b)  hereof), the  Purchase Price  to be  in
  effect after  such record date shall  be determined by multiplying  the
  Purchase Price  in effect immediately  prior to such  record date by  a
  fraction, the  numerator of which shall be  the then current per  share
  market  price of the  Preferred Shares on  such record  date, less  the
  fair  market  value (as  determined  in  good faith  by  the  Board  of
  Directors of the Company,  whose determination shall be described in  a
  statement filed with the Rights Agent) of the portion of the assets  or
  evidences of indebtedness so to be distributed or of such  subscription
  rights  or  warrants   applicable  to  one  Preferred  Share  and   the
<PAGE>
  denominator of  which shall be such current  per share market price  of
  the  Preferred Shares; 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
  to  be issued upon  exercise of one  Right. Such  adjustments shall  be
  made  successively whenever such  a record date  is fixed;  and in  the
  event that such distribution  is not so made, the Purchase Price  shall
  again  be adjusted to  be the  Purchase Price  which would  then be  in
  effect if such record date had not been fixed.

             (d)   (i) For  the  purpose of  any  computation  hereunder,
   other than computations  made pursuant to  Section 11(a)(iii)  hereof,
   the "current per  share market price"  of any  security (a  "Security"
   for the purpose of this Section  11(d)(i) on any date shall be  deemed
   to be  the average  of the  daily  closing prices  per share  of  such
   Security  for the  30  consecutive  Trading  Days  (as  such  term  is
   hereinafter defined) immediately prior to such date, and for  purposes
   of  computations made  pursuant  to  Section  11(a)(iii)  hereof,  the
   "current per share market  price" of a Security  on any date shall  be
   deemed to be  the average  of the daily  closing prices  per share  of
   such  Security  for  the  ten  consecutive  Trading  Days  immediately
   following 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
   (A) a dividend or distribution  on such Security payable in shares  of
   such Security or securities convertible  into shares of such  Security
   (other  than the  Rights),  or  (B) any  subdivision,  combination  or
   reclassification of such Security, and  the ex-dividend date for  such
   dividend or  distribution, or the  record date  for such  subdivision,
   combination or reclassification shall not  have occurred prior to  the
   commencement of  the requisite  thirty (30)  Trading Day  or ten  (10)
   Trading Day period, as set forth  above, then, and in each such  case,
   the "current per  share market price"  shall be  properly adjusted  to
   take into account ex-dividend trading. 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  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 quoted price or, if not  so
   quoted, the average of the high bid and low asked prices in the  over-
   the-counter  market,  as  reported  by  the  National  Association  of
   Securities Dealers,  Inc. Automated  Quotations System  ("NASDAQ")  or
   such other system then in  use, or, if on  any such date the  Security
   is not quoted  by any such  organization, the average  of the  closing
   bid and  asked prices  as  furnished by  a professional  market  maker
   making a market in the Security selected by the Board of Directors  of
   the company. The  term "Trading  Day" shall mean  a day  on which  the
   principal  national securities  exchange  on  which  the  Security  is
   listed or admitted to trading is open for the transaction of  business
   or, if  the Security  is not  listed  or admitted  to trading  on  any
   national securities exchange, a Business Day.

           (ii)  For  the  purpose  of  any  computation  hereunder,  the
  "current per  share market  price" of  the  Preferred Shares  shall  be
  determined in accordance with the method set forth in Section 11(d)(i).
  If the Preferred Shares are not publicly traded, the "current per share
  market price" of the Preferred Shares  shall be conclusively deemed  to
  be the  current  per  share  market  price  of  the  Common  Shares  as
  determined pursuant  to  Section  11(d)i)  (appropriately  adjusted  to
  reflect  any  stock  split,  stock  dividend  or  similar   transaction
  occurring after the  date hereof), multiplied  by 100.  If neither  the
  Common Shares nor the Preferred Shares  are publicly held or so  listed
  or traded, "current per share market  price" shall mean the fair  value
  per share as determined in good faith by the Board of Directors of  the
  Company, whose determination  shall be described  in a statement  filed
  with the Rights Agent and shall be conclusive for all purposes. For all
  purposes of this  Agreement, the "current  per share  market price"  of
  1/100 of a  Preferred Share shall  be equal to  the "current per  share
  market price" of one Preferred Share divided by 100.

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

             (f)    If  as  a  result  of  an  adjustment  made  pursuant
  to Section 11(a) hereof,  the holder of any Right thereafter  exercised
  shall become  entitled to receive  any shares of  capital stock of  the
  Companyother  than  Preferred Shares,  thereafter  the number  of  such
  other shares so receivable upon exercise of any Right shall be  subject
  to  adjustment from time  to time in  a manner and  on terms as  nearly
  equivalent  as  practicable  to the  provisions  with  respect  to  the
  Preferred  Shares contained in  Section 11(a)  through (c),  inclusive,
  and  the provisions of  Sections 7, 9,  10 and 13  with respect to  the
  Preferred Shares shall apply on like terms to any such other shares.

              (g)  All Rights originally issued by the Company subsequent
   to any adjustment made to the Purchase Price hereunder shall  evidence
   the right to purchase, at  the adjusted Purchase Price, the number  of
   one one-hundredths of a Preferred Share purchasable from time to  time
   hereunder  upon  exercise  of  the  Rights,  all  subject  to  further
   adjustment as provided herein.
<PAGE>
              (h)     Unless   the   Company  shall  have  exercised  its
   election as provided  in Section 11(i),  upon each  adjustment of  the
   Purchase Price as a result of the calculations made in Sections  11(b)
   and (c), each  Right outstanding immediately  prior to  the making  of
   such adjustment shall  thereafter evidence the  right to purchase,  at
   the adjusted Purchase  Price, that number of  one one-hundredths of  a
   Preferred Share  (calculated to  the nearest  one one-millionth  of  a
   Preferred Share) obtained  by (i) multiplying  (x) the  number of  one
   one-hundredths of  a share  covered by  a Right  immediately prior  to
   this adjustment by (y) the Purchase Price in effect immediately  prior
   to such  adjustment  of the  Purchase  Price, and  (ii)  dividing  the
   product so obtained by the Purchase Price in effect immediately  after
   such adjustment of the Purchase Price.

                   (i)     The Company may elect on or after the date  of
   any adjustment of the Purchase  Price to adjust the number of  Rights,
   in  substitution  for  any  adjustment  in  the  number  of  one  one-
   hundredths of a  Preferred Share purchasable  upon the  exercise of  a
   Right. Each of  the Rights outstanding  after such  adjustment of  the
   number of  Rights shall  be exercisable  for the  number of  one  one-
   hundredths of  a Preferred  Share for  which a  Right was  exercisable
   immediately prior to such adjustment. Each Right held of record  prior
   to such adjustment  of the number of  Rights shall become that  number
   of Rights (calculated to the  nearest one ten-thousandth) obtained  by
   dividing the Purchase Price in effect immediately prior to  adjustment
   of the  Purchase Price  by the  Purchase Price  in effect  immediately
   after adjustment  of the  Purchase  Price. The  Company shall  make  a
   public announcement of  its election to adjust  the number of  Rights,
   indicating the record  date for the adjustment,  and, if known at  the
   time, the amount of  the adjustment to be  made. This record date  may
   be the  date  on which  the  Purchase Price  is  adjusted or  any  day
   thereafter, but, if the Right Certificates have been issued, shall  be
   at least 10 days  later than the date  of the public announcement.  If
   Right 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 Right  Certificates on such  record date Right  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  Right
   Certificates held by  such holders prior  to the  date of  adjustment,
   and upon  surrender thereof,  if required  by the  Company, new  Right
   Certificates evidencing all the Rights to which such holders shall  be
   entitled  after  such   adjustment.  Right  Certificates   so  to   be
   distributed shall be issued, executed and countersigned In the  manner
   provided for  herein  and shall  be registered  in  the names  of  the
   holders of record of Right  Certificates on the record date  specified
   in the public announcement.

                   (j)     Irrespective of  any adjustment  or change  in
   the Purchase Price or the number of one one-hundredths of a  Preferred
   Share  issuable   upon  the  exercise   of  the   Rights,  the   Right
   Certificates  theretofore  and  thereafter  issued  may  continue   to
   express the Purchase Price and  the number of one one-hundredths of  a
   Preferred  Share   which   were  expressed   in  the   initial   Right
   Certificates issued hereunder.
<PAGE>
                   (k)     Before taking any action  that would cause  an
   adjustment reducing the Purchase Price below one one-hundredth of  the
   then  par value,  if  any,  of  the  Preferred  Shares  issuable  upon
   exercise of the  Rights, the Company shall  take any corporate  action
   which may, in the opinion of  its counsel, be necessary in order  that
   the  Company   may  validly   and  legally   issue  fully   paid   and
   nonassessable Preferred Shares at such adjusted Purchase Price.

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

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

                   (n)  Anything herein to the contrary notwithstanding,
   in  the  event  that  at  any   time   after   the   date   of   this
   Agreement and prior  to the Distribution Date,  the Company shall  (i)
   declare or pay  any dividend on  the Common Shares  payable in  Common
   Shares or (ii) effect a  subdivision, combination or consolidation  of
   the Common Shares  (by reclassification or  otherwise than by  payment
   of dividends  in Common Shares)  into a  greater or  lesser number  of
   Common Shares,  then in  any such  case  (A) the  number of  one  one-
   hundredths of  a Preferred  Share purchasable  after such  event  upon
   proper exercise of each Right  shall be determined by multiplying  the
   number of  one  one-hundredths of  a  Preferred Share  so  purchasable
   immediately prior to such event by a fraction, the numerator of  which
   is the  number of Common  Shares outstanding  immediately before  such
   event and  the denominator of  which is  the number  of Common  Shares
   outstanding immediately after  such event, and  (B) each Common  Share
   outstanding  immediately after  such  event  shall  have  issued  with
   respect  to  it  that  number  of  Rights  which  each  Common   Share
   outstanding immediately prior  to such event  had issued with  respect
   to it. The  adjustments provided for  in this Section  11(n) shall  be
   made successively  whenever such  a dividend  is declared  or paid  or
   such a subdivision, combination or consolidation is effected.
<PAGE>
                   Section 12. Certificate of Adjusted Purchase Price  or
   Number of  Shares.  Whenever an  adjustment  is made  as  provided  in
   Section 11  or  Section 13  hereof,  the Company  shall  promptly  (a)
   prepare a  certificate  setting forth  such  adjustment, and  a  brief
   statement of the facts accounting  for such adjustment, (b) file  with
   the Rights Agent  and with each transfer  agent for the Common  Shares
   or the Preferred  Shares a  copy of such  certificate and  (c) mail  a
   brief summary thereof  to each holder of  a Right Certificate (or,  if
   prior to  the  Distribution Date,  to  each holder  of  a  Certificate
   representing Common Shares) in accordance with Section 25 hereof.

                   Section 13. Consolidation. Merger or Sale or  Transfer
   of Assets or Earning Power. In the event that at any time on or  after
   the Distribution Date, directly or  indirectly, (a) the Company  shall
   consolidate with, or merge with and into, any other Person other  than
   a Subsidiary of  the Company, (b) any  Person other than a  Subsidiary
   of the Company shall consolidate  with the Company, or merge with  and
   into the Company and the Company shall be the continuing or  surviving
   corporation of such  merger and, in connection  with such merger,  all
   or part of the  Common Shares shall be  changed into or exchanged  for
   stock or  other securities of  any other  Person (or  the Company)  or
   cash  or any  other  property,  or  (c)  the  Company  shall  sell  or
   otherwise transfer (or one or  more of its Subsidiaries shall sell  or
   otherwise transfer), in  one or more  transactions, assets or  earning
   power aggregating 50% or  more of the assets  or earning power of  the
   Company and its  Subsidiaries (taken as a  whole) to any other  Person
   other  than  the   Company  or  one  or   more  of  its   wholly-owned
   Subsidiaries (any  such event  described in  clauses (a),  (b) or  (c)
   being referred to  herein as a "Flip-Over  Event"), then, and in  each
   such case, proper provision shall be  made so that (i) each holder  of
   a Right (except  as otherwise provided  herein) shall thereafter  have
   the right to receive,  upon the exercise thereof  at a price equal  to
   the then current Purchase Price  multiplied by the number of one  one-
   hundredths  of  a   Preferred  Share  for  which   a  Right  is   then
   exercisable, in accordance  with the terms  of this  Agreement and  in
   lieu of Preferred Shares, such  number of Common Shares of such  other
   Person  (including  the  Company  as  successor  thereto  or  as   the
   surviving corporation)  as  shall equal  the  result obtained  by  (A)
   multiplying the then current Purchase Price by the number of one  one-
   hundredths of a Preferred Share for which a Right is then  exercisable
   and dividing that  product by (B)  50% of the  then current per  share
   market price of  the Common Shares  of such  other Person  (determined
   pursuant to Section 11(d) hereof) on the date of consummation of  such
   consolidation, merger,  sale  or transfer;  (ii)  the issuer  of  such
   Common Shares shall  thereafter be liable  for, and  shall assume,  by
   virtue  of such  consolidation,  merger,  sale or  transfer.  all  the
   obligations and  duties of  the Company  pursuant to  this  Agreement;
   (iii) the term "Company" shall  thereafter be deemed to refer to  such
   issuer; and (iv)  such issuer shall  take such  steps (including,  but
   not limited to, the reservation  of a sufficient number of its  Common
   Shares in accordance  with Section 9 hereof)  in connection with  such
   consummation as may be necessary to assure that the provisions  hereof
   shall thereafter be  applicable, as nearly  as reasonably  may be,  in
   relation  to  the  Common  Shares  thereafter  deliverable  upon   the
   exercise of  the Rights.  The Company  shall not  consummate any  such
   consolidation, merger,  sale  or  transfer unless  prior  thereto  the
   Company and  such issuer  shall  have executed  and delivered  to  the
<PAGE>
   Rights Agent a supplemental agreement so providing. The Company  shall
   not enter  into  any transaction  of  the  kind referred  to  in  this
   Section 13 if at  the time of such  transaction there are any  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. 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  Right  Certificates   which
   evidence fractional Rights. In lieu  of such fractional Rights,  there
   shall be  paid to  the registered  holders of  the Right  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.
   The closing price for  any day shall be  the last sale price,  regular
   way. or, in case no such sale takes place on such day, the average  of
   the closing  bid and  asked prices,  regular way,  in either  case  as
   reported in the  principal consolidated  transaction reporting  system
   with respect to  securities listed or admitted  to trading on the  New
   York Stock Exchange or,  if the Rights are  not listed or admitted  to
   trading on the New York  Stock Exchange, as reported in the  principal
   consolidated transaction reporting  system with respect to  securities
   listed or  admitted to trading  on the  principal national  securities
   exchange on which the Rights are listed or admitted to trading or,  if
   the Rights  are not  listed or  admitted to  trading on  any  national
   securities exchange, the last quoted  price or, if not so quoted,  the
   average of the high bid  and low asked prices in the  over-the-counter
   market, as reported by NASDAQ or such other system then in use or,  if
   on any such date the Rights  are not quoted by any such  organization,
   the average of  the closing  bid and asked  prices as  furnished by  a
   professional market maker  making a market in  the Rights selected  by
   the Board of  Directors of the Company.  If on any  such date no  such
   market maker is making a market in  the Rights, the fair value of  the
   Rights on  such date  as determined  in  good faith  by the  Board  of
   Directors of the Company shall be used.

                   (b)     The Company  shall not  be required  to  issue
   fractions  of  Preferred  Shares  (other  than  fractions  which   are
   integral multiples  of one one-hundredth  of a  Preferred Share)  upon
   exercise of the  Rights or to  distribute certificates which  evidence
   fractional Preferred Shares (other  than fractions which are  integral
   multiples of  one one-hundredth of  a Preferred  Share). Fractions  of
   Preferred Shares  in  integral multiples  of  one one-hundredth  of  a
   Preferred Share may. at the  election of the Company, be evidenced  by
   depositary receipts, pursuant to an appropriate agreement between  the
   Company  and  a  depositary  selected  by  it;  provided,  that   such
   agreement shall provide that the  holders of such depositary  receipts
   shall have all  the rights, privileges and  preferences to which  they

<PAGE>
   that are not  integral multiples of one  one-hundredth of a  Preferred
   Share, the  Company  shall pay  to  the registered  holders  of  Right
   Certificates at the time such Rights are exercised as herein  provided
   an amount in  cash equal to  the same fraction  of the current  market
   value of one Preferred Share. For the purposes of this Section  14(b),
   the current market  value of a  Preferred Share shall  be the  closing
   price of  a Preferred  Share  (as determined  pursuant to  the  second
   sentence of Section 11(d)(ii) hereof) for the Trading Day  immediately
   prior to the date of such exercise.

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

             (d)  The holder  of a Right by  the acceptance of the  Right
   expressly waives his  right to receive  any fractional  Rights or  any
   fractional  shares upon  exercise  of  a  Right  (except  as  provided
   above).

        Section 15. Rights of Action. All rights of action in respect  of
   this Agreement, excepting  the rights of  action given  to the  Rights

   registered  holders of  the  Right  Certificates (and,  prior  to  the
   Distribution Date, the registered holders  of the Common  Shares); and
   any registered  holder of  any  Right 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  Right Certificate  (or,
   prior to the  Distribution Date, of  the Common Shares),  may,  in his
   own behalf and  for his own  benefit. enforce, and  may institute  and
   maintain  any suit,  action  or  proceeding  against  the  Company  to
   enforce, or otherwise  act in respect  of. his right  to exercise  the
   Rights evidenced by such Right  Certificate in the manner  provided in
   such Right  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  hereunder, and
   injunctive relief  against  actual  or threatened  violations  of  the
   obligations of any Person subject to, this Agreement.

        Section 16. Agreement of Right 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;
<PAGE>
             (b)  after  the Distribution  Date, the  Right  Certificates
   are transferable only  on the registry  books of the  Rights Agent  if
   surrendered  at  the  principal  office  of  the  Rights  Agent,  duly
   endorsed or accompanied  by a proper instrument  of transfer and  with
   the appropriate forms and certificates fully executed;

             (c)  the  Company and the  Rights Agent may  deem and  treat
   the person  in whose  name the  Right 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
   Right 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 obligations;  provided, however,  the
   Company must use reasonable efforts to have any such order, decree  or
   ruling lifted or otherwise overturned as soon as possible.

             Section   17.  Right   Certificate  Holder   Not  Deemed   a
   Shareholder. No holder,  as such, of  any Right  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
   Right Certificate be construed to confer upon the holder of any  Right
   Certificate, as  such,  any of  the rights  of  a shareholder  of  the
   Company or any  right to vote  for the election  of directors or  upon
   any matter submitted  to shareholders at  any meeting  thereof, or  to
   give or  withhold  consent to  any  corporate action,  or  to  receive
   notice of meetings or other actions affecting shareholders (except  as
   provided  in  Section   25  hereof),  or   to  receive  dividends   or
   subscription  rights,  or  otherwise,   until  the  Right  or   Rights

   adopt  the  countersignature  of  the  predecessor  Rights  Agent  and
   deliver such Right Certificates so countersigned; and in case at  that

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

   certificate signed by any one of the Chairman of the Board, the  Chief
   Executive Officer, the  President, any Vice  President, the  Treasurer

   manner, method or amount thereof)  provided for in Section 3, 11.  13,
   23 or 24,  or the ascertaining  of the existence  of facts that  would

   exercise  of Rights  evidenced  by  Right  Certificates  after  actual
   notice that such  change or adjustment is  required); nor shall it  by
   any act hereunder be deemed to make any representation or warranty  as

   issued pursuant to  this Agreement or any  Right Certificate or as  to
   whether any Preferred Shares will, when issued, be validly  authorized
   and issued, fully paid and nonassessable,

   acknowledge  and  deliver   or  cause  to   be  performed,   executed,

   securities or property purchasable  under the Right Certificates  made
   in accordance with the provisions of this Agreement

             Section 23 Redemption.

   option, at any time prior to the close of business on the seventh  day
   following a Shares Acquisition Date, redeem all but not less than  all
   the then outstanding Rights at  a redemption price of $.01 per  Right,
   appropriately adjusted to reflect any  stock spilt, stock dividend  or
   similar transaction occurring after  the date hereof (such  redemption
   price being hereinafter  referred to as  the "Redemption Price").  The
   redemption of the Rights by the Board of

             Directors may be made effective at such time. on such  basis
   and with  such  conditions as  the  Board  of Directors  in  its  sole
   discretion may establish.  Notwithstanding anything in this  Agreement
   to  the contrary,  the  Rights  shall not  be  exercisable  after  the
   occurrence of a Flip-In Event  until such time as the Company's  right
   of redemption hereunder has expired.

                  (b)   Immediately  upon the  action  of  the  Board  of
   Directors  of the  Company  ordering  the  redemption  of  the  Rights
   pursuant to paragraph (a) of this Section 23. and without any  further
   action and without any notice,  the right to exercise the Rights  will
   terminate and  the only  right  thereafter of  the holders  of  Rights
   shall be to receive the  Redemption Price, The Company shall  promptly
   give public notice of any  such redemption, provided however that  the
   failure to give, or  any defect in, any  such notice shall not  affect
   the validity of such redemption.  Within 10 days after such action  of
   the Board  of Directors  ordering the  redemption of  the Rights,  the
   Company shall mail a  notice of redemption to  all the holders of  the
   then outstanding Rights  at their last addresses  as they appear  upon
<PAGE>
   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 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) The Board of Directors of  the Company may, at  its
   option, at  any time  after any  Person becomes  an Acquiring  Person,
   exchange all or  part of the then  outstanding and exercisable  Rights
   (which shall not include Rights that have become void pursuant to  the
   provisions of  Section 11(a)(ii)(B) hereof)  for Common  Shares at  an
   exchange ratio of one Common  Share per Right, appropriately  adjusted
   to reflect  any stock  split, stock  dividend or  similar  transaction
   occurring  after   the  date   hereof  (such   exchange  ratio   being
   hereinafter referred to as the "Exchange Ratio"). Notwithstanding  the
   foregoing, the Board  of Directors shall  not be  empowered to  effect
   such exchange at  any time after any  Person (other than the  Company,
   any 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 of the Company ordering the exchange of any Rights  pursuant
   to paragraph (a)  of this Section  24 and without  any further  action
   and without  any  notice, the  right  to exercise  such  Rights  shall
   terminate and the  only right thereafter  of a holder  of such  Rights
   shall be to receive that number  of Common Shares equal to the  number
   of such Rights held by  such holder multiplied by the Exchange  Ratio.
   The Company shall  promptly give public notice  of any such  exchange;
   provided, however that  the failure to  give, or any  defect in,  such
   notice shall not  affect the validity  of such  exchange. The  Company
   promptly shall  mail a  notice of  any  such exchange  to all  of  the
   holders of such  Rights at their  last addresses as  they appear  upon
   the registry books of the Rights Agent. Any notice which is mailed  in
   the manner herein provided shall  be deemed given, whether or not  the
   holder receives the  notice. Each such notice  of exchange will  state
   the method by which the exchange of the Common Shares for Rights  will
   be effected and, in the event  of any partial exchange, the number  of
   Rights  which  will  be  exchanged.  Any  partial  exchange  shall  be
   effected pro rata  based on the  number of Rights  (other than  Rights
   which  have  become  void  pursuant  to  the  provisions  of   Section
   1l(a)(ii)(B) hereof) held by each holder of Rights.

                  (c)  In any exchange pursuant  to this Section 24.  the
   Company,  at  its   option,  may  substitute   Preferred  Shares   (or
   equivalent preferred shares, as such term is defined in Section  11(b)
   hereof) for  Common Shares  exchangeable for  Rights, at  the  initial
   rate  of  one  one-hundredth  of  a  Preferred  Share  (or  equivalent
<PAGE>
   preferred share) for each Common  Share, as appropriately adjusted  to
   reflect adjustments  in  the voting  rights  of the  Preferred  Shares
   pursuant to the  terms thereof, so  that the fraction  of a  Preferred
   Share delivered  in lieu  of each  Common Share  shall have  the  same
   voting rights as one Common Share.

                  (d) In the event that the number of Common or Preferred
   Shares  which   are   authorized   by  the   Company's   Articles   of
   Incorporation  but  not  outstanding  or  reserved  for  issuance  for
   purposes other than upon exercise of the Rights are not sufficient  to
   permit any exchange of Rights as contemplated in accordance with  this
   Section 24, the Company  may, at its option,  take all such action  as

        of the preceding sentence  shall be adjusted by multiplying  such
        amount by  a fraction  the numerator of  which is  the number  of
        shares of Common Stock  outstanding Immediately after such  event
        and the denominator  of which is the  number of shares of  Common

        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  Company shall  at any  time  declare or  pay  any
        dividend on the Common  Stock payable in shares of Common  Stock,
        or effect a  subdivision or combination  or consolidation of  the
        outstanding  shares  of  Common  Stock  (by  reclassification  or
        otherwise than  by payment  of  a dividend  in shares  of  Common
        Stock)  Into a  greater  or lesser  number  of shares  of  Common
        Stock,  then in  each  such ease  the  amount set  forth  in  the
        preceding sentence  with respect  to the  exchange or  change  of
        shares  of  Series  P  Preferred  Stock  shall  be  adjusted   by

                       SUMMARY OF RIGHTS TO PURCHASE

                             PREFERRED SHARES

             On September 19, 1991, the Board of Directors of  Carrington
        Laboratories, Inc.  (the "Company")  declared a  dividend of  one
        preferred share purchase right  (a "Right") for each  outstanding
        share of  common stock, par  value $0.01 per  share (the  "Common
        Shares"), of the Company. the dividend is payable on October  15,
        1991 (the "Record  Date") to the shareholders  of record on  that
        date. Each Right entitles the registered holder to purchase  from
        the Company one  one-hundredth of a share  of Series D  Preferred
        Stock, par value $100 per share (the "Preferred Shares"), of  the
        Company at a  price of $80 per  one one-hundredth of a  Preferred
        Share  (the  "Purchase   Price"),  subject  to  adjustment.   The
        description and  terms of the  Rights are set  forth in a  Rights
        Agreement  (the  "Rights  Agreement")  between  the  Company  and
        Ameritrust Company  National Association;  as Rights  Agent  (the
        "Rights Agent").

             Until  the earlier  to  occur of  (i)  10 days  following  a
        public  announcement that  a person  or  group of  affiliated  or
        associated   persons  (an   "Acquiring  Person")   has   acquired
        beneficial ownership  of 20% or  more of  the outstanding  Common
        Shares or (ii)  10 business days  (or such later  date as may  be
        determined by  action of  the hoard  of Directors  prior to  such
        time as  any person or  group of affiliated  persons becomes  all
        Acquiring Person) following the commencement of. or  announcement
        of an  intention to make.  * tender offer  or exchange offer  the
        consummation of  which would result  in the beneficial  ownership
        by a person  or group of  20% or more  of the outstanding  Common
        Shares (the earlier of such dates being called the  "Distribution
        Date"), the Rights will be evidenced, with respect to any of  the
        Common Share certificates outstanding  as of the Record Date,  by
        such Common Share certificate.

             The Rights Agreement  provides that, until the  Distribution
        Date (or  earlier redemption or  expiration of  the Rights),  the
        Rights will be transferred with and only with the Common  Shares.
        Until the Distribution Date (or earlier redemption or  expiration
        of the Rights),  new Common Share  certificates issued after  the
        Record Date upon transfer  or new issuance of Common Shares  will
        contain  a  notation   incorporating  the  Rights  Agreement   by
        reference. Until the Distribution Date (or earlier redemption  Or
        expiration of  the Rights),  the surrender  for transfer  of  any
        certificates  for Common  Shares  outstanding as  of  the  Record
        Date,  even  without such  notation,  will  also  constitute  the
        transfer  of  the  Rights  associated  with  the  Common   Shares
        represented  by   such  certificate.  As   soon  as   practicable
        following   the   Distribution   Date,   separate    certificates
        evidencing the  Rights ("Right Certificates")  will be mailed  to
        holders  of record  of  the Common  Shares  as of  the  close  of
        business  on  the Distribution  bate,  and  such  separate  Right
        Certificates alone will evidence the Rights.
<PAGE>
             The Rights are not exercisable until the Distribution  Date.
        The  Rights  will  expire   On  October  15,  2001  (the   "Final
        Expiration Date"), unless the  Final Expiration Date is  extended
        or unless  the Rights are  earlier redeemed or  exchanged by  the
        Company, in each case, as described below.

             The Purchase  Price  payable, and  the number  of  Preferred
        Shares or  other securities or  property issuable, upon  exercise
        of the  Rights are  subject to adjustment  from time  to time  to
        prevent dilution (I) in  the event of a  stock dividend on, or  a
        subdivision, combination  or reclassification  of, the  Preferred
        Shares, (ii) upon  the grant to holders  of the Preferred  Shares
        of  certain rights  or  warrants  to subscribe  for  or  purchase
        Preferred  Shares at  a  price, or  securities  convertible  into
        Preferred Shares  with a conversion  price, less  than the  then-
        current market price  of the Preferred Shares  or (iii) upon  the
        distribution to holders of  the Preferred Shares of evidences  of
        indebtedness   or  assets   (excluding  regular   periodic   cash
        dividends paid out of earnings or retained earnings or  dividends
        payable  in  Preferred  Shares)  or  of  subscription  rights  or
        warrants (other than those referred to above).

             The number of outstanding Rights and the number of one  one-
        hundredths of a  Preferred Share issuable  upon exercise of  each
        Right are  also subject  to adjustment in  the event  of a  stock
        split of  the Common  Shares or a  stock dividend  on the  Common
        Shares payable in  Common Shares or subdivisions,  consolidations
        or  combinations of  the Common  Shares  occurring, in  any  such
        case, prior to the Distribution Date.

             Preferred  Shares purchasable  upon exercise  of the  Rights
        will not be redeemable. Each Preferred Share will be entitled  to
        receive a dividend payable  in cash, stock or otherwise when,  as
        and  if declared  by the  Board of  Directors.  In the  event  of
        liquidation,  the  holders  of  the  Preferred  Shares  will   be
        entitled to  a minimum preferential  liquidation payment of  $100
        per share  but will be  entitled to an  aggregate payment of  100
        times the  payment made per  Common Share.  each Preferred  Share
        Will have  100 votes,  voting together  with the  Common  Shares.
        Finally,  in the  event of  any  merger, consolidation  Or  other
        transaction in which Common Shares are exchanged, each  Preferred
        Share will be entitled to receive 100 times. the amount  received
        per  Common  Share,  These  rights  are  protected  by  customary
        antidilution provisions.

             Because  of the nature  of the  Preferred Shares'  dividend,
        liquidation and  voting rights,  the value  of one  one-hundredth
        interest in a Preferred  Share purchasable upon exercise of  each
        Right should approximate the value of one Common Share.
<PAGE>
             In the  event that the  Company is acquired  in a merger  or
        other business  combination transaction  or 50%  or more  of  its
        consolidated  assets or  earning  power are  sold  (a  "Flip-Over
        Event"), proper provision will be  made so that each holder of  a
        Right  will  thereafter have  the  right  to  receive,  upon  the
        exercise  thereof at  the  then  current exercise  price  of  the
        Right, that  number of shares  of common stock  of the  acquiring
        company which at the time of such transaction will have a  market
        value of two times the exercise price of the Right. In the  event
        that any  person or  group of  affiliated or  associated  persons
        becomes an Acquiring  Person other than  pursuant to a  Flip-Over
        Event, proper provision  shall be made so  that each holder of  a
        Right, other  than  Rights beneficially  owned by  the  Acquiring
        Person (which will thereafter be void), will thereafter have  the
        right to receive upon exercise that number of Common Shares  (or,
        in certain circumstances, cash,  property or other securities  of
        the Company)  having a market  value of two  times, the  exercise
        price of the Right.

             At any  time after any  Person becomes  an Acquiring  Person
        and prior to the  acquisition by such person  or group of 50%  or
        more of the outstanding Common Shares, the hoard or Directors  of
        the Company may exchange  the Rights (other than Rights owned  by
        such person or  group which will have  become void). in whole  or
        in part, at an  exchange ratio of one  Common Share, or one  one-
        hundredth of  a Preferred  Share (or  of a  share of  a class  or
        series  of  the  Company's  preferred  stock  having   equivalent
        rights,  preferences  and  privileges),  per  Right  (subject  to
        adjustment).

             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. No  fractional
        Preferred Shares will be  issued (other than fractions which  are
        integral multiples  of one  one-hundredth of  a Preferred  Share,
        which  may, at  the  election of  the  Company, be  evidenced  by
        depositary receipts) and, in lieu thereof, an adjustment in  cash
        will be made  based on the market  price of the Preferred  Shares
        on the last trading day prior to the date of exercise.

             At any  time prior to  the dose of  business on the  Seventh
        day  following the  first  date  of public  announcement  that  a
        person  or  group  became  an  Acquiring  Person,  the  Board  of
        Directors of the Company may redeem the Rights in whole, but  not
        in part, at a price  of $0.01 per Right (the "Redemption  Print).
        The redemption of the Rights may be made effective at such  time,
        on such basis and with such conditions as the Board of  Directors
        in  its  sole discretion  may  establish.  Immediately  upon  any
        redemption of the Rights,  the right to exercise the Rights  will
        terminate, and the  only right of the  holders of Rights will  be
        to receive the Redemption Price.

             The terms  of the  Rights may  be amended  by the  Board  of
        Directors of the  Company without the consent  of the holders  of
        the Rights,  including an amendment  to tower certain  thresholds
        described above to not  less than the greater  of (i) the sum  of
        .001%  and  the largest  percentage  of  the  outstanding  Common
        Shares then known to the Company to be beneficially owned by  any
        person or  group of  affiliated or  associated persons  and  (ii)
        10%, except that from and after such time as any person or  group
        of affiliated or associated  persons becomes an Acquiring  Person
        no  such amendment  may adversely  affect  the interests  of  the
        holders of the Rights.

             Until  a Right is  exercised, the holder  thereof, as  such,
        will have no rights  as a shareholder of the Company,  including,
        without limitation, the right to vote or to receive dividends.

             A  copy of  the  Rights Agreement  has  been filed  with the
        Securities  and   Exchange  Commission   as  an   Exhibit  to   a
        Registration Statement on Form 8-A. dated September ___, 1991.  A
        copy of  the Rights Agreement  is available free  of charge  from
        the Company.  This summary  description of  the Rights  does  not
        purport  to be  complete  and is  qualified  in its  entirety  by
        reference to the Rights  Agreement, which is hereby  incorporated
        herein by reference.
