Merger   Agreement  and  certain  of  the  Stock  Option   Agreements,   and  in

HOLDER are parties,  the parties hereto,  intending to be legally bound,  hereby
agree as follows:
                  1.  GRANT OF OPTION.
                  (a) Subject to the  receipt of all  regulatory  approvals  and
orders  required  by OPTION  GRANTOR as set forth in  Section  4.4(c) of the WPL
Disclosure Schedule to the Merger Agreement and by OPTION HOLDER as set forth in
Section 5.4(c) of the IES Disclosure  Schedule to the Merger  Agreement,  OPTION
GRANTOR hereby grants OPTION HOLDER an irrevocable  option (the "OPTION  GRANTOR
Option")  to  purchase up to that  number of shares,  subject to  adjustment  as
provided in Section 12 (the "OPTION GRANTOR Shares"), of common stock, par value
$.01 per share, of OPTION GRANTOR (the "OPTION GRANTOR Common Stock") equal to a
percentage (the "Option Shares  Percentage"),  which Option Shares Percentage is
equal to the  OPTION  HOLDER's  Participation  Percentage  as  defined  below in
subsection (e), of 6,123,944  shares of OPTION GRANTOR Common Stock (being 19.9%
of the number of shares of OPTION GRANTOR Common Stock issued and outstanding as
of November 10, 1995, the "Initial  Number") in the manner set forth below, at a
price (the "Exercise Price") per OPTION GRANTOR Share of $30.675 (which is equal
to the Fair Market Value (as defined  below) of a OPTION GRANTOR Share as of the
date hereof).
                  (b) The Exercise Price shall  be  payable,  at OPTION HOLDER's
option, as follows:
                           (i)   in cash, or
                           (ii)  subject to the receipt of all  approvals of any
         Governmental  Authority  required  for OPTION  GRANTOR to acquire,  and
         OPTION HOLDER to issue,  the OPTION  HOLDER  Shares (as defined  below)
         from OPTION HOLDER,  in shares of common stock, no par value, of OPTION
         HOLDER ("OPTION HOLDER Shares"),
in either case in accordance with Section 4 hereof.
                  (c) Notwithstanding  the  foregoing,  in no event  shall  the
number  of  OPTION  GRANTOR  Shares  for  which  the  OPTION  GRANTOR  Option is
exercisable  exceed the product of the Option Shares  Percentage and the Initial
Number, subject to adjustment as provided in Section 12.
                  (d) As used herein, the "Fair Market Value" of any share shall
be the average of the daily  closing  sales price for such share on the New York
Stock  Exchange (the "NYSE") during the ten NYSE trading days prior to the fifth
NYSE trading day preceding the date such Fair Market Value is to be determined.
                  (e) For  purposes of this  Agreement  the term  "Participation
Percentage"  shall have the same meaning as in Section  10.3(f)(i) of the Merger
Agreement,  except that the numerator and denominator  shall be calculated based
on the number of shares of WPL
                                     - 2 -
Common  Stock which would be issuable  (or, in the case of WPL,  retained by its
shareholders) on a fully diluted basis had the Effective Time occurred as of the
date on which the  Exercise  Notice is delivered  under  Section 2 hereof or the
date on which demand for the Trigger  Payment (as defined herein) is given under
Section 5 hereof,  as the case may be. Other  capitalized  terms used herein but
not defined herein shall have the meanings set forth in the Merger Agreement.
                  2.  EXERCISE OF OPTION.
                  (a) The  OPTION  GRANTOR  Option  may be  exercised  by OPTION
HOLDER,  in whole or in part,  at any time or from time to time after the Merger
Agreement becomes  terminable by OPTION HOLDER under  circumstances  which could
entitle OPTION HOLDER to a termination  fee under Section  10.3(a) of the Merger
Agreement  (provided that the events specified in Section  10.3(a)(ii)(A) of the
Merger  Agreement shall have occurred,  although the events specified in Section
10.3(a)(ii)(B) thereof need not have occurred), or Section 10.3(b) of the Merger
Agreement  (regardless of whether the Merger Agreement is actually terminated or
whether  there occurs a closing of any Business  Combination  involving a Target
Party or a closing by which a Target Party becomes a Subsidiary), any such event
by which the Merger  Agreement  becomes so  terminable  by OPTION  HOLDER  being
referred to herein as a "Trigger Event").
                  (b)      (i)  OPTION   GRANTOR  shall  notify  OPTION  HOLDER
         promptly in writing of the  occurrence of any Trigger  Event,  it being
         understood  that the giving of such notice by OPTION  GRANTOR shall not
         be a condition  to the right of OPTION  HOLDER to  exercise  the OPTION
         GRANTOR Option.
                           (ii) In the event  OPTION  HOLDER  wishes to exercise
         the  OPTION  GRANTOR  Option,  OPTION  HOLDER  shall  deliver to OPTION
         GRANTOR  written  notice (an "Exercise  Notice")  specifying  the total
         number of OPTION GRANTOR Shares it wishes to purchase.
                           (iii)  Upon the  giving  by  OPTION  HOLDER to OPTION
         GRANTOR  of the  Exercise  Notice  and  the  tender  of the  applicable
         aggregate Exercise Price, OPTION HOLDER, to the extent permitted by law
         and OPTION GRANTOR's  organizational  documents,  and provided that the
         conditions to OPTION  GRANTOR's  obligation to issue the OPTION GRANTOR
         Shares  to OPTION  HOLDER  hereunder  set forth in  Section 3 have been
         satisfied or waived,  shall be deemed to be the holder of record of the
         OPTION GRANTOR Shares issuable upon such exercise, notwithstanding that
         the stock transfer books of OPTION GRANTOR shall then be closed or that
         certificates  representing such OPTION GRANTOR Shares shall not then be
         actually delivered to OPTION HOLDER.
                           (iv) Each  closing  of a purchase  of OPTION  GRANTOR
         Shares (a "Closing")  shall occur at a place,  on a date, and at a time
         designated  by OPTION HOLDER in an Exercise  Notice  delivered at least
         two business days prior to the date of the Closing.
                                     - 3 -
                  (c) The  OPTION  GRANTOR  Option  shall  terminate  upon  the 
earliest to occur of:
                           (i)   the Effective Time of the Merger;
                           (ii)  the   termination  of  the  Merger   Agreement
         pursuant to Section 10.1 thereof,  other than under circumstances which
         also constitute a Trigger Event under this Agreement;
                           (iii) 180  days  following  any  termination  of the
         Merger  Agreement upon or during the continuance of a Trigger Event (or
         if, at the expiration of such 180 day period, the OPTION GRANTOR Option
         cannot  be  exercised  by reason of any  applicable  judgment,  decree,
         order,  law or regulation,  ten business days after such  impediment to
         exercise  shall have been  removed or shall have  become  final and not
         subject to appeal,  but in no event under this clause  (iii) later than
         May 10, 1998); and
                           (iv) payment by OPTION GRANTOR of the Trigger Payment
         set forth in Section 5 of this Agreement to OPTION HOLDER.
                  (d) Notwithstanding  the foregoing,  the OPTION GRANTOR Option
may not be  exercised if (i) OPTION  HOLDER is in material  breach of any of its
representations or warranties,  or in material breach of any of its covenants or
agreements,  contained in this Agreement or in the Merger  Agreement,  or (ii) a
Trigger  Payment has been paid pursuant to Section 5 of this Agreement or demand
therefor has been made and not withdrawn.

                  (c)  prior  to  any  delivery  of  OPTION   HOLDER  Shares  in
consideration of the purchase of OPTION GRANTOR Shares pursuant  hereto,  OPTION
HOLDER will have taken all necessary  corporate action to authorize for issuance
and to permit it to issue such OPTION HOLDER  Shares,  all of which,  upon their
issuance and delivery in accordance  with the terms of this  Agreement,  will be
duly authorized, validly issued, fully paid and nonassessable;
                  (d) upon any delivery of such OPTION  HOLDER  Shares to OPTION
GRANTOR in  consideration  of the  purchase of OPTION  GRANTOR  Shares  pursuant
hereto,  OPTION  GRANTOR will acquire the OPTION HOLDER Shares free and clear of
all claims,  liens,  charges,  encumbrances and security interests of any nature
whatsoever;
                  (e)  except  as  described  in  Section   5.4(b)  of  the  IES
Disclosure Schedule to the Merger Agreement,  the execution and delivery of this
Agreement by OPTION  HOLDER does not, and the  consummation  by OPTION HOLDER of
the transactions contemplated hereby will not, violate, conflict with, or result
in the breach of any  provision  of, or  constitute  a default  (with or without
notice or a lapse of time, or both) under,  or result in any Violation by OPTION
HOLDER or any of its Subsidiaries, pursuant to
                             (i) any provision of the Articles of  Incorporation
         or Bylaws of OPTION HOLDER,
                             (ii) any Material  Contract of OPTION HOLDER or any
         of its subsidiaries or to which any of them is a party, or
                             (iii) any judgment,  order, decree,  statute,  law,
         ordinance,  rule or  regulation  applicable  to  OPTION  HOLDER  or its
         properties or assets,
which  Violation,  in the case of each of clauses  (ii) or (iii),  would have an
OPTION HOLDER Material Adverse Effect;
                  (f)  except  as  described  in  Section   5.4(c)  of  the  IES
Disclosure  Schedule  to the  Merger  Agreement  or  Section 1 or 3 hereof,  the
execution  and  delivery of this  Agreement  by OPTION  HOLDER does not, and the
consummation by OPTION HOLDER of the transactions  contemplated hereby will not,
require  any  consent,  approval,  authorization  or permit of,  filing  with or
notification to, any Governmental Authority; and
                  (g) any OPTION  GRANTOR  Shares  acquired upon exercise of the
OPTION  GRANTOR  Option will be acquired for OPTION  HOLDER's  own account,  for
investment  purposes only and will not be, and the OPTION  GRANTOR Option is not
being, acquired by OPTION HOLDER with a view to the public distribution thereof,
in violation of any applicable provision of the Securities Act.
                  8.  CERTAIN REPURCHASES.
                  (a) OPTION  HOLDER "PUT".  At  the request of OPTION HOLDER by
written notice (x) at  any  time  during  which  the  OPTION  GRANTOR  Option is
exercisable
                                     - 9 -
pursuant  to  Section  2 (the  "Repurchase  Period"),  OPTION  GRANTOR  (or  any
successor  entity  thereof)  shall,  if permitted by applicable  law, the OPTION
GRANTOR Articles and Bylaws and OPTION GRANTOR's Material Contracts,  repurchase
from OPTION HOLDER all or any portion of the OPTION GRANTOR Option, at the price
set forth in subparagraph  (i) below,  or, (y) at any time prior to May 10, 1997
(provided  that  such  date  shall  be  extended  to  May  10,  1998  under  the
circumstances  where the date after which either party may  terminate the Merger
Agreement  pursuant to Section 10.1(b) of the Merger Agreement has been extended
to May 10, 1998),  OPTION GRANTOR (or any successor  entity  thereof)  shall, if
permitted by applicable  law, the OPTION GRANTOR  Articles and Bylaws and OPTION
GRANTOR's Material  Contracts,  repurchase from OPTION HOLDER all or any portion
of the OPTION GRANTOR Shares  purchased by OPTION HOLDER  pursuant to the OPTION
GRANTOR Option, at the price set forth in subparagraph (ii) below:
                         (i) (A) The difference between the "Market/Offer Price"
         (as defined  below) for shares of OPTION GRANTOR Common Stock as of the
         date OPTION  HOLDER  gives  notice of its intent to exercise its rights
         under this Section 8 and the Exercise  Price,  multiplied by the number
         of OPTION  GRANTOR  Shares  purchasable  pursuant to the OPTION GRANTOR
         Option (or  portion  thereof  with  respect to which  OPTION  HOLDER is
         exercising   its  rights  under  this  Section  8),  but  only  if  the
         Market/Offer Price is greater than the Exercise Price.
                             (B) for purposes  of  this Agreement, "Market/Offer
         Price")  shall  mean,  as of any date,  the higher of (I) the price per
         share offered as of such date pursuant to any tender or exchange  offer
         or other offer with respect to a Business Combination  involving OPTION
         GRANTOR as the Target  Party  which was made prior to such date and not
         terminated  or withdrawn as of such date and (II) the Fair Market Value
         of OPTION GRANTOR Common Stock as of such date.
                        (ii) (A) the product of (I) the sum of (a) the  Exercise
         Price paid by OPTION HOLDER per OPTION GRANTOR Share acquired  pursuant
         to the OPTION GRANTOR Option, and (b) the difference between the "Offer
         Price" (as defined below) and the Exercise Price, but only if the offer
         Price is greater that the Exercise Price, and (II) the number of OPTION
         GRANTOR Shares so to be repurchased pursuant to this Section 8.
                             (B) For  purposes  of  this clause (ii), the "Offer
         Price"  shall be the  highest  price per share  offered  pursuant  to a
         tender or exchange offer or other Business  Combination offer involving
         OPTION GRANTOR as the Target Party during the  Repurchase  Period prior
         to the delivery by OPTION HOLDER of a notice of repurchase.
                  (b) REDELIVERY OF OPTION HOLDER SHARES. If OPTION HOLDER shall
have  previously  elected to  purchase  OPTION  GRANTOR  Shares  pursuant to the
exercise of the OPTION  GRANTOR  Option by the  issuance  and delivery of OPTION
HOLDER Shares,  then OPTION GRANTOR shall, if so requested by OPTION HOLDER,  in
fulfillment of its obligation pursuant to Section 8(a)(y) (that is, with respect
to the  Exercise  Price only and without  limitation  to its  obligation  to pay
additional consideration under clause
                                     - 10 -
(b) of Section  8(a)(ii)(A)(I)),  redeliver  the  certificates  for such  OPTION
HOLDER Shares to OPTION HOLDER, free and clear of all liens, claims, charges and
encumbrances of any kind or nature whatsoever; provided, however, that if at any
time less than all of the OPTION  GRANTOR  Shares so purchased by OPTION  HOLDER
pursuant to the OPTION  GRANTOR  Option are to be  repurchased by OPTION GRANTOR
pursuant to Section  8(a)(y),  then (i) OPTION  GRANTOR  shall be  obligated  to
redeliver to OPTION  HOLDER the same  proportion of such OPTION HOLDER Shares as
the number of OPTION  GRANTOR  Shares that OPTION  GRANTOR is then  obligated to
repurchase  bears to the  number of OPTION  GRANTOR  Shares  acquired  by OPTION
HOLDER upon exercise of the OPTION  GRANTOR  Option and (ii) OPTION HOLDER shall
issue to OPTION GRANTOR new certificates representing those OPTION HOLDER Shares
which are not due to be  redelivered  to OPTION HOLDER  pursuant to this Section
8(b) to the  extent  that  excess  OPTION  HOLDER  Shares  are  included  in the
certificates redelivered to OPTION HOLDER by OPTION GRANTOR.
                  (c)  PAYMENT  AND  REDELIVERY  OF OPTION  GRANTOR  OPTIONS  OR
SHARES.  In the event OPTION  HOLDER  exercises its rights under this Section 8,
OPTION  GRANTOR  shall,  within ten business days  thereafter,  pay the required
amount to OPTION HOLDER in immediately  available  funds and OPTION HOLDER shall
surrender to OPTION  GRANTOR the OPTION  GRANTOR  Option or the  certificate  or
certificates  evidencing the OPTION  GRANTOR  Shares  purchased by OPTION HOLDER
pursuant hereto, and OPTION HOLDER shall warrant that it owns the OPTION GRANTOR
Option or such shares and that the OPTION GRANTOR Option or such shares are then
free and clear of all liens,  claims,  damages,  charges and encumbrances of any
kind or nature whatsoever.
                  (d) OPTION  HOLDER  "CALL".  If OPTION  HOLDER has  elected to
purchase  OPTION GRANTOR  Shares  pursuant to the exercise of the OPTION GRANTOR
Option by the  issuance and delivery of OPTION  HOLDER  Shares,  notwithstanding
that OPTION  HOLDER may no longer hold any such  OPTION  GRANTOR  Shares or that
OPTION  HOLDER  elects not to exercise  its other  rights  under this Section 8,
OPTION  HOLDER  may  require,  at any time or from time to time prior to May 10,
1997  (provided  that such date  shall be  extended  to May 10,  1998  under the
circumstances  where the date after which either party may  terminate the Merger
Agreement  pursuant to Section 10.1(b) of the Merger Agreement has been extended
to May 10, 1998), OPTION GRANTOR to sell to OPTION HOLDER any such OPTION HOLDER
Shares at the price  attributed to such OPTION HOLDER Shares pursuant to Section
4 plus  interest  at the rate of 8.75% per annum on such amount from the Closing
Date relating to the exchange of such OPTION HOLDER Shares pursuant to Section 4
to the Closing Date under this  Section  8(d) less any  dividends on such OPTION
HOLDER Shares paid during such period or declared and payable to stockholders of
record on a date during such period.
                  (e) REPURCHASE PRICE REDUCED AT OPTION HOLDER'S OPTION. In the
event the repurchase  price specified in Section 8(a) would subject the purchase
of the OPTION GRANTOR  Option or the OPTION  GRANTOR Shares  purchased by OPTION
HOLDER  pursuant to the OPTION GRANTOR Option to a vote of the  shareholders  of
OPTION GRANTOR pursuant to applicable law or the OPTION GRANTOR Articles, then
                                     - 11 -
OPTION HOLDER may, at its  election,  reduce the  repurchase  price to an amount
which would permit such repurchase  without the necessity for such a shareholder
vote.
                  9.  VOTING OF SHARES.  Following  the date hereof and prior to
the fifth  anniversary of the date hereof (the  "Expiration  Date"),  each party
shall vote any shares of capital stock of the other party acquired by such party
pursuant to this Agreement  ("Restricted  Shares"),  including any OPTION HOLDER
Shares issued pursuant to Section 1(b), or otherwise  beneficially owned (within
the meaning of Rule 13d-3 promulgated under the Securities Exchange Act of 1934,
as amended (the "Exchange  Act")),  by such party on each matter  submitted to a
vote of shareholders of such other party for and against such matter in the same
proportion as the vote of all other  shareholders  of such other party are voted
(whether by proxy or otherwise) for and against such matter.
                  10. RESTRICTIONS ON TRANSFER.
                  (a) RESTRICTIONS ON TRANSFER.  Prior to the Expiration  Date,
neither party shall,  directly or indirectly,  by operation of law or otherwise,
sell, assign,  pledge, or otherwise dispose of or transfer any Restricted Shares
beneficially  owned by such party, other than (i) pursuant to Section 8, or (ii)
in accordance with Section 10(b) or Section 11.
                  (b) PERMITTED  SALES.  Following the termination of the Merger
Agreement, a party shall be permitted to sell any Restricted Shares beneficially
owned by it if such sale is made pursuant to a tender or exchange offer that has
been approved or recommended,  or otherwise  determined to be fair to and in the
best  interests of the  shareholders  of the other  party,  by a majority of the
members of the Board of  Directors  of such other party,  which  majority  shall
include a majority of directors who were directors prior to the  announcement of
such tender or exchange offer.
                  11. REGISTRATION RIGHTS.
                  (a) Following the termination of the Merger Agreement,  either
party hereto that owns Restricted Shares (a "Designated  Holder") may by written
notice (the "Registration Notice") to the other party (the "Registrant") request
the  Registrant  to  register  under the  Securities  Act all or any part of the
Restricted Shares beneficially owned by such Designated Holder (the "Registrable
Securities")  pursuant  to a  bona  fide  firm  commitment  underwritten  public
offering,  in which the Designated  Holder and the underwriters  shall effect as
wide a distribution of such Registrable  Securities as is reasonably practicable
and shall use their best efforts to prevent any person  (including any Group (as
used in Rule 13d-5 under the Exchange Act)) and its affiliates  from  purchasing
through  such  offering  Restricted  Shares  representing  more  than  1% of the
outstanding shares of common stock of the Registrant on a fully diluted basis (a
"Permitted Offering").
                                     - 12 -
                  (b)  The  Registration  Notice  shall  include  a  certificate
executed by the Designated Holder and its proposed managing  underwriter,  which
underwriter  shall  be an  investment  banking  firm  of  nationally  recognized
standing (the "Manager"), stating that
                           (i) they  have a good  faith  intention  to  commence
         promptly a Permitted Offering, and
                           (ii) the manager in good faith believes  that,  based
         on the then-prevailing  market conditions,  it will be able to sell the
         Registrable  Securities  at a per share  price equal to at least 80% of
         the then Fair Market Value of such shares.
                  (c)  The  Registrant  (and/or  any  person  designated  by the
Registrant)  shall  thereupon  have the option  exercisable  by  written  notice
delivered to the Designated Holder within ten business days after the receipt of
the Registration Notice, irrevocably to agree to purchase all or any part of the
Registrable  Securities  proposed to be so sold for cash at a price (the "Option
Price") equal to the product of (i) the number of  Registrable  Securities to be
so  purchased  by the  Registrant  and (ii) the then Fair  Market  Value of such
shares.
                  (d) Any purchase of  Registrable  Securities by the Registrant
(or its  designee)  under Section 11(c) shall take place at a closing to be held
at the principal  executive  offices of the  Registrant or at the offices of its
counsel at any reasonable date and time designated by the Registrant and/or such
designee in such  notice  within  twenty  business  days after  delivery of such
notice,  and any  payment  for the  shares to be so  purchased  shall be made by
delivery at the time of such closing in immediately available funds.
                  (e) If the  Registrant  does not elect to exercise  its option
pursuant to this Section 11 with respect to all Registrable Securities, it shall
use its best efforts to effect,  as promptly as  practicable,  the  registration
under the Securities Act of the unpurchased  Registrable  Securities proposed to
be so sold; provided, however, that
                           (i)  neither  party  shall be entitled to demand more
         than an aggregate of two effective  registration  statements hereunder,
         and
                           (ii) the Registrant  will not be required to file any
         such registration statement during any period of time (not to exceed 40
         days after  such  request in the case of clause (A) below or 90 days in
         the case of clauses (B) and (C) below) when
                                (A) the  Registrant is in possession of material
                  non-public  information which it reasonably  believes would be
                  detrimental  to be  disclosed at such time and, in the opinion
                  of  counsel  to the  Registrant,  such  information  would  be
                  required to be  disclosed  if a  registration  statement  were
                  filed at that time;
                                (B)  the   Registrant  is  required   under  the
                  Securities Act to include audited financial statements for any
                  period  in such  registration  statement  and  such  financial
                  statements  are  not  yet  available  for  inclusion  in  such
                  registration statement; or
                                     - 13 -
                                (C) the Registrant determines, in its reasonable
                  judgment,  that such  registration  would  interfere  with any
                  financing, acquisition or other material transaction involving
                  the Registrant or any of its affiliates.
                  (f) The Registrant  shall use its  reasonable  best efforts to
cause any Registrable  Securities  registered  pursuant to this Section 11 to be
qualified for sale under the  securities or Blue Sky laws of such  jurisdictions
as the  Designated  Holder  may  reasonably  request  and  shall  continue  such
registration or qualification in effect in such jurisdiction; provided, however,
that the  Registrant  shall not be  required  to qualify to do  business  in, or
consent to general  service of process  in, any  jurisdiction  by reason of this
provision.
                  (g) The  registration  rights set forth in this Section 11 are
subject to the condition that the Designated Holder shall provide the Registrant
with such information with respect to such holder's Registrable Securities,  the
plans for the distribution  thereof,  and such other information with respect to
such holder as, in the  reasonable  judgment of counsel for the  Registrant,  is
necessary to enable the Registrant to include in such registration statement all
material  facts  required  to  be  disclosed  with  respect  to  a  registration
thereunder.
                  (h) A  registration  effected  under this  Section 11 shall be
effected at the  Registrant's  expense,  except for  underwriting  discounts and
commissions  and the fees and the expenses of counsel to the Designated  Holder,
and  the  Registrant  shall  provide  to  the  underwriters  such  documentation
(including  certificates,   opinions  of  counsel  and  "comfort"  letters  from
auditors) as is customary in connection with  underwritten  public  offerings as
such underwriters may reasonably require.
                  (i) In connection  with any  registration  effected under this
Section 11, the parties agree
                           (i) to indemnify each other and the  underwriters  in
         the customary manner,
                           (ii) to enter into an underwriting  agreement in form
         and substance  customary for transactions of such type with the Manager
         and the other underwriters participating in such offering, and
                          (iii)  to take  all  further  actions  which  shall be
         reasonably necessary to effect such registration and sale (including if
         the   Manager   deems  it   necessary,   participating   in   road-show
         presentations).
                  (j) The  Registrant  shall  be  entitled  to  include  (at its
expense)  additional  shares  of its  common  stock in a  registration  effected
pursuant  to this  Section 11 only if and to the extent the  Manager  determines
that such inclusion will not adversely  affect the prospects for success of such
offering.
                  12.  ADJUSTMENT  UPON  CHANGES  IN   CAPITALIZATION.   Without
limitation to any  restriction on OPTION GRANTOR  contained in this Agreement or
in the Merger  Agreement,  in the event of any change in OPTION  GRANTOR  Common
Stock by
                                     - 14 -
reason  of  stock  dividends,   splitups,   mergers  (other  than  the  Merger),
recapitalizations,  combinations,  exchange of shares or the like,  the type and
number of shares or securities  subject to the OPTION  GRANTOR  Option,  and the
purchase price per share provided in Section 1, shall be adjusted  appropriately
to  restore  to OPTION  HOLDER  its  rights  hereunder,  including  the right to
purchase from OPTION GRANTOR (or its successors) shares of OPTION GRANTOR Common
Stock (or such other shares or securities into which OPTION GRANTOR Common Stock
has been so changed)  representing  the Option Shares  Percentage of the Initial
Number of shares of OPTION GRANTOR Common Stock for the aggregate Exercise Price
calculated as of the date of this Agreement as provided in Section 1.
                  13. RESTRICTIVE LEGENDS. Each certificate  representing OPTION
GRANTOR Shares issued to OPTION HOLDER  hereunder,  and OPTION HOLDER Shares, if
any,  delivered  to  OPTION  GRANTOR  at a  Closing,  shall  include a legend in
substantially the following form:
         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED,  OR ANY STATE  SECURITIES
         OR BLUE SKY LAWS, AND MAY BE REOFFERED OR SOLD ONLY IF SO REGISTERED OR
         IF AN EXEMPTION FROM SUCH  REGISTRATION  IS AVAILABLE.  SUCH SECURITIES
         ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN
         THE OPTION HOLDER STOCK OPTION AND TRIGGER PAYMENT AGREEMENT,  DATED AS
         OF NOVEMBER 10,  1995, A COPY OF WHICH MAY BE OBTAINED  FROM THE ISSUER
         UPON REQUEST.
It is understood and agreed that:
                           (i) the reference to the resale  restrictions  of the
         Securities  Act and  state  securities  or Blue Sky  laws in the  above
         legend  shall be  removed  by  delivery  of  substitute  certificate(s)
         without such reference if OPTION HOLDER or OPTION GRANTOR,  as the case
         may be, shall have delivered to the other party a copy of a letter from
         the staff of the SEC, or an opinion of counsel,  in form and  substance
         satisfactory  to the other party, to the effect that such legend is not
         required for purposes of the Securities Act or such laws;
                           (ii)  the   reference  to  the   provisions  to  this
         Agreement  in  the  above  legend  shall  be  removed  by  delivery  of
         substitute  certificate(s)  without  such  reference if the shares have
         been sold or  transferred  in  compliance  with the  provisions of this
         Agreement and under  circumstances that do not require the retention of
         such reference; and
                           (iii) the legend  shall be removed in its entirety if
         the  conditions  in  the  preceding  clauses  (i)  and  (ii)  are  both
         satisfied.
                                     - 15 -
In addition, such certificates shall bear any other legend as may be required by
law.  Certificates  representing  shares sold in a  registered  public  offering
pursuant  to  Section 11 shall not be  required  to bear the legend set forth in
this Section 13.
                  14.   BINDING   EFFECT;   NO   ASSIGNMENT;   NO  THIRD   PARTY
BENEFICIARIES. (a) This Agreement shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and permitted assigns.
                  (b)  Except  as  expressly  provided  for in  this  Agreement,
neither this  Agreement nor the rights or obligations of either party hereto are
assignable, except by operation of law, or with the written consent of the other
party.
                  (c) Nothing  contained in this Agreement,  express or implied,
is intended to confer  upon any person  other than the parties  hereto and their
respective  permitted assigns any rights or remedies of any nature whatsoever by
reason of this Agreement.
                  (d) Any Restricted  Shares sold by a party in compliance  with
the provisions of Section 11 shall,  upon  consummation of such sale, be free of
the restrictions  imposed with respect to such shares by this Agreement,  unless
and until such party shall  repurchase or otherwise  become the beneficial owner
of such shares,  and any  transferee of such shares shall not be entitled to the
registration rights of such party.
                  15.  SPECIFIC  PERFORMANCE.  The  parties  hereto  agree  that
irreparable  harm would  occur in the event that any of the  provisions  of this
Agreement were not performed in accordance  with their  specified  terms or were
otherwise  breached.  It is accordingly  agreed that the parties hereto shall be
entitled to an injunction or injunctions  to prevent  breaches of this Agreement
and to enforce  specifically the terms and provisions hereof in any court of the
United  States or any state having  jurisdiction,  this being in addition to any
other remedy to which they are entitled at law or equity.
                  16. VALIDITY.  (a) The invalidity or  unenforceability  of any
provision of this Agreement shall not affect the validity or  enforceability  of
the other  provisions  of this  Agreement,  which shall remain in full force and
effect.
                  (b) In the event any court or other competent  authority holds
any provisions of this Agreement to be null, void or unenforceable,  the parties
hereto shall  negotiate in good faith the execution and delivery of an amendment
to this Agreement in order, as nearly as possible, to effectuate,  to the extent
permitted  by law,  the  intent  of the  parties  hereto  with  respect  to such
provision and the economic effects thereof.
                  (c)  Subject to Section 5, if for any reason any such court or

OPTION  GRANTOR is not permitted to  repurchase  pursuant to Section 8, the full
number of shares of OPTION GRANTOR Common Stock provided in Section 1 hereof (as
the same may be  adjusted),  it is the express  intention  of OPTION  GRANTOR to
allow OPTION HOLDER to acquire or to require OPTION  GRANTOR to repurchase  such
lesser  number  of  shares  as may  be  permissible  without  any  amendment  or
modification hereof.

competent  authority  hold any provision of this  Agreement or part hereof to be
null, void or unenforceable,  or order any party to take any action inconsistent
herewith,  or not take any action required herein,  the other party shall not be
entitled  to specific  performance  of such  provision  or part hereof or to any
other remedy,  including but not limited to money damages,  for breach hereof or
of any other  provision  of this  Agreement or part hereof as the result of such
holding or order.
