                                PROXY STATEMENT
 
                            ------------------------
 
                                     VOTING
 
    This Proxy Statement is furnished in connection with the solicitation by the
Board  of Directors of Zenith National  Insurance Corp. ("Zenith") of proxies to
be voted  at  the  Annual Meeting  of  Stockholders  of Zenith  to  be  held  on
Wednesday,  May 22,  1996, at  9:00 a.m., and  at any  adjournments thereof (the
"Annual Meeting"). Any proxy given pursuant to this solicitation may be  revoked
at  any time prior to its exercise by  written notice to Zenith, and the persons
executing the same, if in attendance at  the Annual Meeting, may vote in  person
instead  of by proxy. Unless authority therefor is withheld, all proxies will be
voted as  provided therein.  In addition  to solicitation  of proxies  by  mail,
officers  and regular employees of Zenith and its subsidiaries, who will receive
no additional compensation therefor, may solicit proxies by telephone,  telegram
or  personal interview. The subsidiaries of  Zenith are Zenith Insurance Company
("Zenith Insurance"), CalFarm  Insurance Company  ("CalFarm"), Cal-Ag  Insurance
Services,  Inc.,  CalFarm  Annuity Service  Company,  CalFarm  Insurance Agency,
CalFarm  Properties,  Inc.,  CalRehab  Services,  Inc.,  Perma-Bilt,  a   Nevada
Corporation,  Zenith Star  Insurance Company, ZIC  Lloyd's Underwriting Limited,
and ZNAT  Insurance Company.  The cost  of this  solicitation will  be borne  by
Zenith.   In  addition,  Zenith  will   reimburse  brokerage  houses  and  other
custodians,  nominees  and  fiduciaries  for  expenses  incurred  in  forwarding
solicitation materials to stockholders.
 
    The  approximate date on which this Proxy Statement and accompanying form of
proxy are first being sent to stockholders is March 29, 1996.
 
    Only stockholders of record at the close of business on March 27, 1996,  the
record  date for the Annual Meeting (the  "Record Date"), are entitled to notice
of and to vote at such meeting. On such date, Zenith had outstanding  17,657,004
shares  of Common Stock,  $1.00 par value  per share (the  "Common Stock"). Each
share of Common Stock entitles the record holder at such time to one vote on all
matters. With  respect  to  the  election  of  Directors  only,  however,  every
stockholder  may cumulate his votes with  respect to candidates whose names have
been placed in nomination prior to the vote if, but only if, any stockholder has
given notice at the Annual Meeting prior to voting of his intention to  cumulate
his  votes.  In  the  event  there  is  cumulative  voting  for  Directors, each
stockholder will be entitled to give one candidate the number of votes equal  to
the number of Directors to be elected multiplied by the number of votes to which
the  stockholder's shares are entitled,  or to distribute his  votes on the same
principle among as many candidates as such stockholder thinks fit. In the  event
the  election of Directors is  to proceed with cumulative  voting, the holder of
any proxy  given  pursuant to  this  solicitation  will have  the  authority  to
cumulate  the votes  to which shares  covered by  the proxy are  entitled and to
distribute the votes  among the  candidates for election  as the  holder of  the
proxy  sees fit. The presence, in person  or by proxy, of stockholders holding a
majority of the issued and outstanding  shares of common stock entitled to  vote
shall  constitute a quorom. Election of  Directors shall be decided by plurality
vote. Other matters submitted for  stockholder approval require the  affirmative
vote of
 
                                       1
<PAGE>
the  majority of shares present in person or represented by proxy at the meeting
and entitled to  vote on the  subject matter. Abstentions  and broker  non-votes
(except  on matters for which brokers lack discretionary authority to vote under
New York Stock Exchange rules) will be counted and will have the same effect  as
"no" votes.
 
    The Board of Directors knows of no matters to come before the Annual Meeting
other  than the matters  referred to in  this Proxy Statement.  If, however, any
matters properly come before  the meeting, it  is the intention  of each of  the
persons  named in the accompanying proxy to vote such proxies in accordance with
his best judgment thereon.

      COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT OF 1934
 
    Section  16(a) of the  Securities Exchange Act of  1934 (the "Exchange Act")
and the regulations of the Securities and Exchange Commission (the "Commission")
thereunder require Zenith's  Executive Officers and  Directors, and persons  who
own  more than ten percent of a  registered class of Zenith's equity securities,
to file reports of  ownership and changes in  ownership with the Commission  and
the  New York Stock Exchange and to furnish Zenith with copies of all such forms
they file.
 
    Based solely on its review  of the copies of such  forms received by it  and
written  representations from  certain reporting persons,  Zenith believes that,
during the year ended December 31,  1995, all filing requirements applicable  to
its  Executive  Officers, Directors,  and 10%  stockholders were  complied with,
except that due  to an  inadvertent error,  Mr. Silbert did  not file  a Form  4
reporting the sale of 7,500 shares of Common Stock by a family trust of which he
is trustee. Mr. Silbert has subsequently filed a Form 5 reporting the sale.
 
                             ELECTION OF DIRECTORS
                             (ITEM 1 ON PROXY CARD)
 
    It  is the  intention of  the persons  named in  the enclosed  proxy, unless
otherwise specifically instructed, to vote the proxies received by them for  the
election  of the nominees listed  in the table below  as Directors of Zenith. In
the event that there should be  cumulative voting in the election of  Directors,
as  set forth in this Proxy Statement  under "Voting" above, it is the intention
of such persons  to distribute the  votes represented by  each proxy among  such
nominees  in  such proportion  as they  see  fit, unless  otherwise specifically
instructed.
 
    All nominees have consented to being  named herein and have indicated  their
intention  to  serve if  elected. In  the  unanticipated event  that any  of the
nominees becomes unable to serve as a Director, the proxies will be voted for  a
substitute nominee in accordance with the best judgment of the person or persons
voting them.
 
    A  Director of Zenith  serves until the next  Annual Meeting of Stockholders
and until his successor is elected and qualified.
 
    The nominees  for Director  listed below  were designated  by the  Board  of
Directors of Zenith. The information with respect to each nominee is as supplied
or confirmed by such nominee.

    The  Board  of  Directors  communicated  frequently  during  the  year ended
December 31, 1995 and held five formal meetings. Zenith's Board of Directors has
a standing  Audit  Committee  and  a Performance  Bonus  Committee  but  has  no
nominating  committee or  any committee  performing similar  functions. The sole
member and  Chairman  of  the  Audit Committee  is  currently  Mr.  Ostrow.  The
functions  of the  Audit Committee  are to recommend  to the  Board of Directors
retention or change of Zenith's independent  auditors; to consider the range  of
audit  and non-audit fees; to  review the independence of  the auditors; to meet
with them  and Zenith's  internal  audit personnel  to  discuss and  review  the
results  of their respective examinations and  audit plans for the ensuing year;
to review the adequacy  of Zenith's system of  internal accounting controls  and
like  matters. This  Committee is  also authorized  to review  and discuss other
matters as it deems appropriate.  During 1995, the Audit Committee  communicated
frequently  with Zenith's financial and accounting and internal audit department
personnel  and  independent  auditors,  including  eight  formal  meetings.  The
Performance  Bonus Committee,  consisting of  Messrs. Ostrow,  Silbert, and Tsai
(Chairman),  is  responsible  for   performance-based  compensation  plans   for
Executive   Officers,  namely,  the   Executive  Officer  Bonus   Plan  and  the
Non-Qualified Stock Option Plan as it relates to grants thereunder to  Executive
Officers.   The  Board  of  Directors   retains  responsibility  for  all  other
compensation matters. The Performance Bonus Committee held one formal meeting in
1995, but  communicated frequently  and also  took action  by unanimous  written
consent.  Each Director, except Mr. Saul P.  Steinberg, attended at least 75% of
the aggregate of all meetings  of the Board of  Directors and of any  committees
thereof on which such Director served.
 
                            DIRECTORS' COMPENSATION
 
    Zenith  pays each Director  (other than Mr. Zax,  who receives no additional
compensation therefor) a fee of $50,000 per annum for serving as a member of the
Board of Directors.  Mr. Ostrow also  receives a  fee of $25,000  per annum  for
serving as the Chairman and sole member of Zenith's Audit Committee.

(1) Options  granted in 1995 are not exercisable during the first year following
    the date of grant. Each  option becomes exercisable as  to 25% of the  total
    number  of underlying shares in the second  year following the date of grant
    and as to an additional 25% in each of the next three years.
 
(2) All options were granted with an option  price equal to the market price  of
    Zenith  Common Stock on the date of grant  (based on the average of high and
    low prices on the New York Stock Exchange for such date).
 
(3) Options granted in 1995  expire on the  earlier to occur  of (a) five  years
    from  the date of grant,  (b) in the event  of termination of the optionee's
    employment, three months from  the date of such  termination, or (c) in  the
    event of the optionee's death, one year from the date thereof and, following
    termination of employment or death, may be exercised only to the extent they
    were  exercisable on the date of the optionee's termination of employment or
    death.
 
(4) The potential gains shown are  net of the option  exercise price and do  not
    include  the effect of any taxes associated with exercise. The amounts shown
    are  for  the  assumed  rates  of  appreciation  only,  do  not   constitute
    projections  of future stock  price performance, and  may not necessarily be
    realized. Actual gains,  if any,  on stock  option exercises  depend on  the
    future  performance  of Zenith  Common  Stock, continued  employment  of the
    optionee through the term of the option, and other factors.

              EMPLOYMENT AGREEMENTS AND TERMINATION OF EMPLOYMENT
                       AND CHANGE IN CONTROL ARRANGEMENTS
 
    Effective December  6, 1994,  Zenith entered  into an  amended and  restated
employment  agreement with  Mr. Zax,  which extends  the expiration  date of his
employment agreement from December  31, 1995 to December  31, 1998. The  amended
and  restated employment agreement provides for an annual base compensation plus
an annual bonus to  be determined under Zenith's  Executive Officer Bonus  Plan.
Under  the agreement,  Mr. Zax's base  compensation is  continued at $1,000,000,
subject to such  other increases as  the Board of  Directors may determine  from
time to time. Upon Mr. Zax's death, Zenith will continue to pay either his wife,
children or estate his base compensation and annual bonus for a period of twelve
months.  If Mr. Zax's  employment is terminated for  disability, he will receive
his base compensation and annual bonus for a period of six months. If Mr.  Zax's
employment is terminated for breach of his employment agreement, he will receive
his  base compensation  through the  end of the  month in  which the termination
occurs. If his employment is terminated for any reason other than for breach  of
his employment agreement, death, or disability, Zenith will pay Mr. Zax his base
compensation and annual bonus through the term of his employment agreement. Upon
a  Change in  Control (as  defined in the  employment agreement)  of Zenith, all
stock options and stock  appreciation rights granted to  Mr. Zax, to the  extent
not  exercisable at such  time, become immediately  exercisable. In addition, if
Mr. Zax's employment is terminated subsequent to any Change in Control either by
Mr. Zax within 180  days of the Change  in Control or by  Zenith for any  reason
other than disability or breach of his employment agreement, Mr. Zax is entitled
to receive Severance Payments (as defined below).
 
    Effective  December 6,  1994, Zenith  entered into  an amended  and restated
employment agreement with Ms. Taubitz, which extends the expiration date of  her
employment  agreement from October 1,  1995 to October 1,  1998. The amended and
restated employment agreement provides for  an annual base compensation plus  an
annual  bonus to be  determined under Zenith's Executive  Officer Bonus Plan and
certain additional benefits. The base compensation is $365,000, subject to  such
increases as the Board of Directors may determine from time to time.
 
    Effective  February 16,  1995, Zenith entered  into an  amended and restated
employment agreement with Mr. Tickner, which extends the expiration date of  his
employment  agreement from October 1,  1995 to October 1,  1998. The amended and
restated employment agreement provides for  an annual base compensation plus  an
annual bonus and certain additional benefits. The base compensation is $242,000,
subject  to such increases as the Board  of Directors may determine from time to
time.
 
    Zenith's employment agreements with Ms. Taubitz and Mr. Tickner provide that
if her  or his  employment  is terminated  by Zenith  other  than for  cause  or
disability,  the executive is entitled to  Severance Payments. In addition, each
of Ms. Taubitz and Mr. Tickner may  terminate her or his employment with  Zenith
and  receive Severance Payments should  (a) Mr. Zax cease,  for any reason other
than death  or  disability,  to be  the  full-time  Chairman of  the  Board  and
President  of  Zenith,  (b)  she  or  he  be  prohibited  or  restricted  in the
performance of her or his  duties, (c) any payment due  her or him under her  or
his agreement remain unpaid for more than 60 days, or (d) she or he give written
notice of termination of the employment agreement to Zenith within 180 days of a
Change in Control (as defined in the employment agreements) of Zenith.
 
                                       11
<PAGE>
    For  purposes of the  foregoing, "Severance Payments"  include the following
benefits: (1) in the case  of Mr. Tickner, all  salary payments that would  have
been  payable to the executive for the greater  of (a) the remaining term of the
employment agreement or (b) one year, plus a pro rata portion of any bonus  that
would  have  been  payable  to  the  executive  with  respect  to  the  year  of
termination; (2) in the case of Mr. Zax and Ms. Taubitz, a cash lump sum payment
equal to the greater of (a) twice  the sum of the executive's then current  base
compensation  and  the highest  annual bonus  paid or  payable during  the three
consecutive years immediately  preceding termination  of employment  or (b)  the
actuarial equivalent of the base compensation and annual bonuses that would have
been  payable  to  the executive  under  the  remaining term  of  the employment
agreement; (3)  continuation of  life, disability,  dental, accident  and  group
health  insurance benefits, plus an additional amount necessary to reimburse the
executive for any taxes attributable solely  to the executive's receipt of  such
benefits;  (4) in the case of Ms. Taubitz  and Mr. Tickner, vesting of all stock
option and  similar rights;  and (5)  an additional  payment, if  necessary,  to
assure  that none of the above benefits are  subject to net reduction due to the
imposition of excise taxes  under section 4999 of  the Internal Revenue Code  of
1986, as amended.
 
          COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    In  1995,  all  decisions  on  Executive  Officer  compensation,  other than
decisions related  to performance-based  compensation plans,  were made  by  the
Board of Directors. Mr. Zax, Chairman of the Board and President, is a member of
the  Board  of  Directors, and  except  with  respect to  his  own compensation,
participated  in  the   Board's  deliberations   concerning  Executive   Officer
compensation.
 
    The  Performance Bonus Committee, consisting of Messrs. Ostrow, Silbert, and
Tsai, determines matters  relating to performance-based  compensation plans  for
Executive  Officers. Mr. Silbert is of counsel to the law firm of Loeb and Loeb,
which performed  certain legal  services for  Zenith in  1995. Mr.  Tsai is  the
Chairman,  President,  Chief Executive  Officer, and  a  Director of  Delta Life
Corporation ("Delta Life"), as well as  being the beneficial owner of more  than
10%  of  its outstanding  common stock.  In March  1995, CalFarm  Life Insurance
Company ("CalFarm Life"), then a subsidiary of Zenith, purchased from Delta Life
75,000 shares of Convertible Preferred Stock of Delta Life for $3.75 Million and
75,000 shares  of Common  Stock Class  A of  Delta Life  for $3.75  Million.  In
December 1995, CalFarm Life transferred all of these shares to CalFarm.

                  BONUS COMMITTEE REPORT ON PERFORMANCE BASED
                   COMPENSATION PLANS FOR EXECUTIVE OFFICERS
 
    Zenith's  entire  Board of  Directors  made determinations  with  respect to
compensation of Executive  Officers in 1995,  except with respect  to Mr.  Zax's
compensation,  which is established in Board  actions from which Mr. Zax excuses
himself and in which he does not participate and except with respect to  matters
related  to  performance-based compensation  plans  for Executive  Officers. The
Performance  Bonus   Committee  made   determinations  under   performance-based
compensation  plans  for Executive  Officers.  The Board's  report  on Executive
Compensation and the Performance Bonus Committee's report on its  determinations
shall  not  be  deemed  to  be incorporated  by  reference  through  any general
statement incorporating by reference this proxy statement into any filings under
the Securities Act  of 1933 or  under the  Securities Exchange Act  of 1934  and

    The Board's report on Executive Compensation follows:
 
    EXECUTIVE OFFICERS
    The level of compensation for Executive Officers of Zenith is intended to be
competitive  (that  is,  "attractive") and  to  provide  appropriate incentives.
Executive Officers of Zenith are generally compensated through salary, grants of
stock options,  and  bonuses under  the  Executive Officer  Bonus  Plan  ("Bonus
Plan").  The Bonus  Plan, approved  by the  stockholders of  Zenith at  the 1994
Annual  Meeting,  is  administered  by  the  Performance  Bonus  Committee.  The
Performance  Bonus  Committee also  grants stock  options to  Executive Officers
under Zenith's Non-Qualified Stock  Option Plan. The  report of the  Performance
Bonus Committee follows this report.
 
    The  level of an Executive Officer's base compensation is generally based on
a combination  of (1)  the performance  of Zenith,  (2) the  performance of  the
insurance  subsidiary, if  any, to  which the  Executive Officer  is principally
assigned, and  (3)  a subjective  and  qualitative evaluation  of  the  personal
contribution  made by  the Executive Officer  to Zenith. Success  in these areas
does not translate mechanically  into compensation levels;  the manner in  which
these  factors are taken into account is discretionary with the Board and is not
based on any formulaic weighting.
 
    The performance of Zenith is generally measured by the combined ratio of its
property and casualty  insurance operations  and by  its overall  profitability.
Zenith  strives for and has achieved long  term average combined ratios that are
about 100%. Zenith also  strives for combined ratios  that compare favorably  in
both the short and long term with insurers primarily engaged in writing workers'
compensation  insurance. In addition, Zenith endeavors  to have loss ratios that
are among the lowest for the industry in any rolling previous five year  period.
The  performance of the  Zenith insurance subsidiaries  is generally measured by
the same factors, as applicable.
 
    With respect to the  subjective and qualitative  evaluation of an  Executive
Officer's  personal contribution to the business of Zenith, a variety of factors
are taken into account. These factors vary and include, but are not limited  to,
the  manner in which  the Executive Officer  favorably affects Zenith's combined
ratio and profitability. Equally, if not more, important is the manner in  which
the  Executive  Officer  performs  in  Zenith's  environment,  which  fosters an
entrepreneurial spirit, teamwork, and a commitment to education. Zenith believes
an entrepreneurial spirit  maximizes profits, promotes  sound execution of  good
business  fundamentals, and  maintains a pool  of executive  talent. Teamwork is
crucial to  the effective  and  efficient implementation  of Zenith's  goals.  A
commitment to education means a dedication to lifelong learning and training for
oneself  and creating conditions  so that the  workforce is similarly dedicated.
Such dedication is critical to Zenith's ability not only to meet change, but  to
use  it  to its  competitive advantage.  In such  an environment,  proactive and
innovative approaches are strongly encouraged and rewarded.
 
    On the  operational  side,  activities  that  demonstrate  an  opportunistic
outlook,  anticipation of  changing business  conditions and  the development of
postures to take  advantage of  opportunities to  increase short  and long  term
profits are rewarded. On the administrative side, efficiency, competence, strong
compliance   efforts,  anticipation  and  avoidance  of  problems,  as  well  as
innovation, are rewarded.
 
    Certain of the Executive Officers  are employed under employment  agreements
that provide for minimum base compensation and annual bonuses. Determinations as
to  salary  increases for  these Executive  Officers, as  well as  those without
employment agreements, are  discretionary and  are not made  on the  basis of  a
formulaic  weighting of the  factors described above.  Bonuses are determined in
accordance with the Bonus Plan.

    In 1995, the combined ratio of Zenith's property and casualty operations was
below the combined ratio for the industry as a whole. Given this performance and
taking into account  the subjective  and qualitative  evaluations of  individual
Executive  Officers,  the  level  of  an  individual  Executive  Officer's  base
compensation was  set  accordingly.  Please  see  the  separate  report  of  the
Performance  Bonus Committee for a discussion of the bonuses earned by Executive
Officers in 1995.
 
    STANLEY R. ZAX, CHIEF EXECUTIVE OFFICER
    Mr. Zax is  never present  when the Board  deliberates with  respect to  his
compensation  and, accordingly, does  not participate in  Board decisions on his
own compensation.
 
    Mr. Zax's base  salary for 1995  was set out  in his four  year amended  and
restated  employment agreement executed in 1994. Under the employment agreement,
increases to base compensation are at  the discretion of the Board of  Directors
and  are not based on formulaic weighting  of factors. In determining whether to
grant any salary  increase, the same  performance criteria that  are applied  to
Executive  Officers in general are  applied to Mr. Zax.  Also, as with Executive
Officers generally, bonuses  to Mr. Zax  are determined in  accordance with  the
Bonus Plan.
 
    Taking  the objective and subjective  criteria described above into account,
although  the  Board  was  otherwise  pleased  with  Mr.  Zax's  initiative  and
leadership  during 1995 in selling CalFarm Life Insurance Company, in continuing
Zenith's  expansion  into   other  states,  in   developing  new  products,   in
establishing and maintaining financially sound rates in California's open rating
environment and in increasing the performance of Zenith's investments, the Board
believes Mr. Zax's base compensation should remain at its current level and that
it  is appropriate for any further incentives  and rewards to be under the Bonus
Plan. Please see the  separate report of the  Performance Bonus Committee for  a
discussion of the bonus earned by Mr. Zax in 1995.
 
    SECTION 162(M) POLICY
    Section  162(m) of the  Internal Revenue Code of  1986, as amended ("Code"),
generally limits the federal income tax deduction that a public corporation  may
claim for annual compensation paid to certain executive officers. The limitation
with respect to each affected Executive Officer is $1,000,000 per year. However,
the limitation does not apply to compensation which is performance-based, earned
under a plan approved by Zenith's stockholders and which satisfies certain other
conditions  set forth  in Section 162(m)  and the  regulations thereunder. Stock
option grants awarded to Executive  Officers under Zenith's Non-Qualified  Stock
Option Plan and bonuses payable under the Bonus Plan are intended to comply with
Section  162(m). Accordingly, neither income accruing to Executive Officers upon
exercise of stock options nor the amount of any bonus payment made to  Executive
Officers  under the  Bonus Plan  should be  subject to  the $1,000,000  limit on
deductibility. The Board has determined that it will pay Mr. Zax's annual salary
even though  any portion  in excess  of $1,000,000  would not  be deductible  by
Zenith.

    The   Performance  Bonus   Committee's  report  on   its  determinations  on
performance-based compensation plans for Executive Officers follows:
 
    The  Performance   Bonus   Committee  ("Committee")   is   responsible   for
administering  the Executive Officer Bonus Plan  ("Bonus Plan") and for granting
stock options under the Non-Qualified  Stock Option Plan to Executive  Officers.
In so doing, the Committee implements and reinforces the compensation philosophy
of  the  Board  of  Directors, as  set  out  in the  Board  Report  on Executive
Compensation.
 
EXECUTIVE OFFICER BONUS PLAN
    The Bonus Plan was approved by  the stockholders at the 1994 Annual  Meeting
as  a performance-based compensation plan. It  provides for bonuses to Executive
Officers based upon attainment  by Zenith in any  fiscal year of an  objectively
measured  performance goal, namely a combined ratio that is below the industry's
combined ratio. The Bonus Plan provides for bonuses to Executive Officers up  to
an amount equal to:
 
    100% of his or her salary at the beginning of the fiscal year if the Company
    Combined Ratio for such fiscal year is at least three percentage points, but
    less than five percentage points, below the Industry Combined Ratio or
 
    150% of his or her salary at the beginning of the fiscal year if the Company
    Combined Ratio for such fiscal year is at least five percentage points below
    the Industry Combined Ratio;
 
provided,   however,  in  either  instance,  the  Committee  may,  in  its  sole
discretion, on a case by case basis, reduce such bonus by any amount.
 
    In 1995, Zenith's combined ratio was 103.0% before accrual for bonuses under
the Bonus Plan; the industry's 1995 combined ratio, as estimated and reported by
A.M. Best Company, was 107.2%. Accordingly, the objective performance goal under
the Bonus Plan was met, which the Committee hereby certifies in accordance  with
Section 162(m) of the Internal Revenue Code of 1986, as amended. Pursuant to the
terms  of the  Bonus Plan,  each Executive Officer  may receive  a maximum bonus
equal to 100% of his or her salary in effect as of January 1, 1995.
 
    EXECUTIVE OFFICERS
    The Committee  undertook  a subjective  and  qualitative evaluation  of  the
personal contribution made by each Executive Officer, other than Stanley R. Zax,
the   Chief  Executive  Officer.  This  subjective  and  qualitative  evaluation
considered  the  same  factors  set  out  in  the  Board  Report  on   Executive
Compensation. Based on these evaluations, the Committee exercised its discretion
with  respect to the bonus to be paid  to each Executive Officer and reduced the
amount payable in all cases. For  all Executive Officers, with the exception  of
Mr.  Zax, the total percentage of the bonuses paid was 51.7% of the maximum that
could have been paid.
 
    STANLEY R. ZAX, CHIEF EXECUTIVE OFFICER
    As it  had with  the other  Executive Officers,  the Committee  undertook  a
subjective  and qualitative evaluation of the  personal contribution made by Mr.
Zax. In so doing, the Committee elected not to exercise its discretion  relative
to  any reduction  in the amount  of bonus that  Mr. Zax is  entitled to receive
under the Bonus  Plan. Accordingly, Mr.  Zax's bonus  is 100% of  his salary  in
effect as of January 1, 1995.

STOCK OPTION GRANTS
    From  time to time, options  to purchase Common Stock  are granted under the
Non-Qualified Stock Option  Plan to  Executive Officers by  the Committee.  Such
options  are  considered  a  part  of  compensation  to  recognize  an Executive
Officer's contribution  and  to reinforce  that  Executive Officer's  long  term
commitment  to the  success of  Zenith. The  Committee's determination  to grant
options to an Executive Officer is  based on the recommendation of the  Chairman
of  the Board, subjective  measures and prior grants  to that Executive Officer.
Beyond these general  considerations, there is  no particular formula  governing
the number of shares awarded.
 
    In 1995, options to purchase Common Stock were granted to Executive Officers
as follows:

                         STOCK PRICE PERFORMANCE GRAPH
 
    The  Stock Price Performance Graph compares  the cumulative total returns of
Zenith Common Stock, the Standard and Poor's 500 Stock Index ("S&P 500") and the
Standard and Poor's 500 Property-Casualty Insurance Index ("S&P PC") for a  five
year  period.  The S&P  PC  was selected  by Zenith  to  replace the  Peer Group
previously used.  The change  was made  because the  number of  publicly  traded
companies  in the Peer Group has  been significantly reduced due to acquisitions
over the past two years. The  Commission's regulations require that in the  year
an  index is changed,  cumulative total returns  for the index  replaced also be
included. Accordingly, the  cumulative total returns  for the Peer  Group for  a
five  year period is also  shown on the Stock  Price Performance Graph. The Peer
Group consists  of  Argonaut  Group, Inc.,  Citation  Insurance  Group,  Fremont
General  Corporation and  Pacific Rim  Holding Corporation.  All of  the current
members of the Peer Group are  presently publicly traded. However, some of  them
were  not publicly traded during the entire  five years and the results of those
members are included only for those periods when they were publicly traded.  The
Peer  Group differs  from that  shown in Zenith's  1995 Proxy  Statement in that
public trading of the  common stock of CII  Financial Inc. and American  Premier
Underwriters, Inc. ceased in 1995. Consequently, they have been deleted from the
Peer  Group. Stock price performance  is based on historical  results and is not
necessarily indicative of  future stock price  performance. The following  graph
assumes  $100  is invested  at  the close  of trading  on  the last  trading day
preceding the first  day of  the fifth preceding  fiscal year  in Zenith  Common
Stock, the S&P 500, the S&P PC and the Peer Group. The calculation of cumulative
total  return  assumes  reinvestment of  dividends.  The graph  was  prepared by
Standard and Poor's  Compustat, which  obtained factual  materials from  sources

                            PROPOSAL TO APPROVE THE
                        1996 EMPLOYEE STOCK OPTION PLAN
                             (ITEM 2 ON PROXY CARD)
 
    The  Board of  Directors has adopted,  subject to  stockholder approval, the
Zenith National  Insurance Corp.  1996  Employee Stock  Option Plan  (the  "1996
Employee  Stock Option Plan"), which provides for the grant of stock options and
stock  appreciation  rights  to  officers  and  employees  of  Zenith  and   its
subsidiaries.  The  Non-Qualified  Stock  Option Plan  will  be  terminated upon
stockholder approval of the 1996 Employee Stock Option Plan, except with respect
to the administration of awards outstanding under the Non-Qualified Stock Option
Plan at the  time of  such termination.  The number  of shares  of Common  Stock
reserved  for issuance pursuant  to awards under the  1996 Employee Stock Option
Plan will be  equal to  2,000,000 plus  that number  of shares  of Common  Stock
remaining available for issuance but not subject to outstanding awards under the
Non-Qualified  Stock Option Plan  at the time  of its termination,  which is not
expected to exceed 176,000. The text of  the 1996 Employee Stock Option Plan  is
attached hereto as Annex A.
 
    The  Board of Directors has  adopted the 1996 Employee  Stock Option Plan as
part of its policy to reinforce the long term commitment to Zenith's success  of
those  officers  (including  officers who  are  directors of  Zenith)  and other
employees of Zenith and its subsidiaries who are or will be responsible for such
success; to  facilitate the  ownership of  Zenith's stock  by such  individuals,
thereby  reinforcing  the identity  of their  interests  with those  of Zenith's
stockholders; and  to assist  Zenith in  attracting and  retaining officers  and
other  employees  with  experience  and  ability.  The  Board  of  Directors has
determined that  the  approximately 176,000  shares  of Common  Stock  currently
remaining  available for issuance pursuant to new awards under the Non-Qualified
Stock  Option  Plan  are  insufficient  to  provide  for  the  continued  proper
compensation  and incentivization  of Zenith's  officers and  employees, and has
adopted the 1996 Employee Stock Option Plan in order to address this issue.  The
Board  of Directors believes  that the 1996 Employee  Stock Option Plan reflects
the best interests of Zenith and recommends its approval by stockholders.
 
    The summary that follows is subject to the actual terms of the 1996 Employee
Stock Option Plan.
 
THE 1996 EMPLOYEE STOCK OPTION PLAN
 
    The  1996  Employee  Stock  Option   Plan  provides  for  the  granting   of
nonqualified stock options ("NSOs") to purchase Common Stock, stock appreciation
rights  ("SARs") and limited  stock appreciation rights  ("LSARs"). NSOs granted
under the 1996 Employee Stock Option Plan  may be accompanied by SARs or  LSARs,
or  both ("rights"). Rights may also be  granted independently of NSOs. On March
25, 1996, the closing  market price of  the Common Stock on  the New York  Stock
Exchange was $24.25 per share.
 
PLAN ADMINISTRATION
 
    The  1996 Employee Stock Option Plan will be administered in two parts. With
respect to  employees other  than Executive  Officers of  Zenith, the  Board  of
Directors  will be  the plan administrator.  With respect  to Zenith's Executive
Officers, the  1996 Employee  Stock  Option Plan  will  be administered  by  the
Performance  Bonus  Committee,  or by  another  committee of  Zenith's  Board of
Directors (the  "Committee")  consisting  solely of  two  or  more  non-employee
directors  of Zenith who are "disinterested  persons" within the meaning of Rule
16b-3 promulgated under Section 16 of  the Exchange Act and "outside  directors"
within  the  meaning of  Section  162(m) of  the  Code. Directors  who  serve as
administrators of  the  1996 Employee  Stock  Option  Plan do  not  receive  any
remuneration in such capacity from the 1996 Employee Stock Option Plan. The 1996
Employee  Stock Option Plan provides that no member of the Board of Directors or
the Committee will be liable  for any action or  determination taken or made  in
good  faith with respect to the 1996 Employee Stock Option Plan or any option or
right granted thereunder.
 
                                       18
<PAGE>
    Subject to  the terms  of the  1996  Employee Stock  Option Plan,  the  plan
administrator  has  the right  to  grant awards  to  eligible recipients  and to
determine the terms and conditions of the award agreements evidencing the  grant
of  such awards, including the vesting schedule and option price of such awards,
and the effect, if any, of a change in control of Zenith on the  exercisability,
vesting and potential cash-out of such awards.
 
SECURITIES SUBJECT TO THE 1996 EMPLOYEE STOCK OPTION PLAN
 
    There  will be  reserved for issuance  under the 1996  Employee Stock Option
Plan a number of treasury or  authorized but unissued shares of Zenith's  Common
Stock  equal to 2,000,000 plus  that number of shares  of Common Stock remaining
available for issuance  but not  subject to  outstanding awards  under the  Non-
Qualified  Stock  Option Plan  at  the time  of  its termination,  which  is not
expected to exceed 176,000. The aggregate number of shares of Common Stock as to
which options and  rights may  be granted to  any single  individual during  any
calendar  year  may  not,  subject  to adjustment  as  set  forth  below, exceed
1,000,000.
 
    The 1996 Employee Stock Option Plan  provides that, in the event of  changes
in  the Common  Stock by reason  of a  merger, reorganization, recapitalization,
common stock dividend,  stock split  or similar change,  the plan  administrator
will  make appropriate adjustments  in the aggregate  number of shares available
for issuance under the 1996 Employee Stock  Option Plan and the option price  to
be  paid or the  number of shares  issuable upon the  exercise thereafter of any
option previously granted.
 
ELIGIBILITY
 
    Grants of  options and/or  rights  may be  made  to any  officer  (including
officers  who are directors)  or employee of  Zenith or its  direct and indirect
subsidiaries who is determined by the plan administrator to be in a position  to
contribute to the long-term success of Zenith.
 
EXERCISE OF OPTIONS
 
    Options will vest and become exercisable according to a schedule established
by  the plan administrator.  In the case of  options exercisable by installment,
options not  exercised during  any one  year may  be accumulated  and  exercised
during  the remaining years of  the option. Options will have  a term of no more
than ten  (10) years,  and  any options  that are  not  exercised prior  to  the
expiration of such term will expire without value.
 
    The  section entitled "Death -- Termination of Employment -- Restrictions on
Transfer" describes the  provisions that  relate to  the exercise  of an  option
following termination of employment.
 
    The purchase price of the Common Stock purchased pursuant to the exercise of
an  option will be as determined by the  plan administrator (but will not in any
event be less  than the fair  market value of  the Common Stock  on the date  of
grant)  and  may  be adjusted  in  accordance with  the  antidilution provisions
described in "Securities Subject to the  1996 Employee Stock Option Plan."  Upon
the  exercise of any option, the purchase price must be fully paid in cash, cash
equivalents, by delivery  of Common Stock  equal in market  value to the  option
price,  by means of a cashless exercise  procedure, or, in the discretion of the
plan administrator, with proceeds of a loan from Zenith, or by a combination  of
the foregoing.
 
STOCK APPRECIATION RIGHTS AND LIMITED STOCK APPRECIATION RIGHTS
 
    SARs  and LSARs may be  granted either alone ("Free  Standing Rights") or in
conjunction with all or part of an NSO ("Related Rights"). Upon the exercise  of
an  SAR, a  holder is  entitled to receive  cash, unrestricted  shares of Common
Stock or any combination thereof, as determined by the plan administrator, in an
amount equal to the excess of the fair market value of one share of Common Stock
over the option
 
                                       19
<PAGE>
price per share specified in the related NSO (or in the case of a Free  Standing
Right, the price per share specified in such right), multiplied by the number of
shares in respect of which the SAR is exercised. Upon the exercise of an LSAR, a
holder  is entitled to receive an amount in cash equal in value to the excess of
the Change in Control Price  (as defined by the  plan administrator in the  LSAR
award  agreement) of one share of Common Stock  on the date of exercise over the
option price per share specified in the related  NSO (or in the case of an  LSAR
which  is  a Free  Standing Right,  the price  per share  specified in  the Free
Standing Right) multiplied by the number of shares in respect of which the  LSAR
is exercised.
 
    With respect to SARs and LSARs that are Related Rights, which may be granted
concurrently  with or  after the grant  of an NSO,  each such SAR  and LSAR will
terminate upon  the termination  or exercise  of the  pertinent portion  of  the
related  NSO, and the pertinent  portion of the related  NSO will terminate upon
the exercise of any such  SAR or LSAR. Unless  otherwise determined by the  plan
administrator  at grant, if an SAR or LSAR  is granted with respect to less than
the full number of shares covered by a related NSO, the SAR or LSAR will only be
reduced if and to the extent that  the number of shares covered by the  exercise
or  termination of such NSO exceeds the number of shares not covered by such SAR
or LSAR. LSARs that are Related Rights  can only be exercised within the  30-day
period  following a Change in  Control (as defined by  the plan administrator in
the LSAR award agreement)  and only to  the extent that the  NSOs to which  they
relate  are exercisable. SARs  that are Related  Rights may be  exercised at any
time that the underlying NSO  is exercisable or, at  the discretion of the  plan
administrator,  in certain other limited circumstances. In the case of both SARs
and LSARs that  are Related  Rights, such Related  Rights may  not be  exercised
during  the  first  six months  after  grant except  in  the event  of  death or
disability of the recipient prior to the expiration of the six-month period.
 
    SARs that are Free Standing  Rights may be exercised  at such time or  times
and may be subject to such terms and conditions as may be determined by the plan
administrator at or after grant. LSARs that are Free Standing Rights can only be
exercised within the 30-day period following a Change in Control. In the case of
both SARs and LSARs that are Free Standing Rights, such Free Standing Rights may
not  be exercised during the first six months after grant thereof, except in the
event of death or  disability of the  recipient prior to  the expiration of  the
six-month period. The term of each Free Standing Right will be fixed by the plan
administrator but may not exceed ten years from the date of grant. The price per
share  for each Free  Standing Right will  be set by  the plan administrator but
will not be less than 100% of the  fair market value of a share of Common  Stock
on the date of grant.
 
DEATH -- TERMINATION OF EMPLOYMENT -- RESTRICTIONS ON TRANSFER
 
    If  an  optionee  should  die  while  employed  by  Zenith  or  any  of  its
subsidiaries or within three (3) months  of the termination of such  employment,
any  option held by such optionee may thereafter be exercised, to the extent the
optionee would  have  been entitled  to  do  so at  the  date of  death  or  the
termination  of employment (whichever first occurs) or on such accelerated basis
as the plan administrator may  determine at or after  grant. Such option may  be
exercised at any time within one (1) year from the date of such optionee's death
or  until the expiration of the stated  term of such option, whichever period is
shorter, by  the optionee's  executors or  administrators or  by any  person  or
persons  who shall  have acquired  the option  from the  optionee by  bequest or
inheritance.
 
    In the event  an optionee shall  cease to be  an employee of  Zenith or  its
subsidiaries  other than by reason of death, any option held by the optionee may
be exercised within three (3) months from the date of
 
                                       20
<PAGE>
termination of employment (or  until the expiration of  the stated term of  such
option,  if earlier) to the extent such option was exercisable as of the date of
such termination  of  employment  or  on such  accelerated  basis  as  the  plan
administrator may determine at or after grant.
 
    In  no event may any option be exercisable more than ten years from the date
it is granted.
 
    Except as otherwise determined by the plan administrator in accordance  with
Rule  16b-3, options and rights are  not transferable and are exercisable during
the recipient's lifetime only by the recipient.
 
AMENDMENT; TERMINATION
 
    Except as provided below, the 1996 Employee Stock Option Plan will terminate
ten (10) years  following its approval  by Zenith's stockholders.  The Board  of
Directors  may terminate  or amend  the 1996 Employee  Stock Option  Plan at any
time, except that  stockholder approval  is required  for any  amendment to  (i)
increase  the maximum number  of shares of  stock which may  be issued under the
1996 Employee Stock Option  Plan (except for adjustments  set forth in the  1996
Employee  Stock Option Plan),  (ii) change the class  of individuals eligible to
participate in the 1996 Employee Stock Option Plan, or (iii) extend the term  of
the  1996 Employee Stock  Option Plan or  the period during  which any option or
right may be granted or exercised, but only to the extent required by Rule 16b-3
and/or Section 162(m) of the Code with respect to the material amendment of  any
employee benefit plan maintained by Zenith. Termination or amendment of the 1996
Employee Stock Option Plan will not affect previously granted options or rights,
which will continue in effect in accordance with their terms.
 
PAYMENT OF TAXES
 
    Participants  are required, no later than the  date as of which the value of
an award first  becomes includible in  the gross income  of the participant  for
federal income tax purposes, to pay to Zenith, or make arrangements satisfactory
to  the plan  administrator regarding payment  of, any Federal,  state, or local
taxes of any kind required by law to be withheld with respect to the award.  The
obligations  of Zenith under the 1996 Employee Stock Option Plan are conditional
on the making of such payments or arrangements, and Zenith will have the  right,
to the extent permitted by law, to deduct any such taxes from any payment of any
kind otherwise due to the participant.
 
                       CERTAIN FEDERAL INCOME TAX EFFECTS
 
    Under  current Federal income tax laws, awards under the 1996 Employee Stock
Option Plan will generally have the following tax consequences:
 
NON-QUALIFIED STOCK OPTIONS
 
    A participant will generally not be taxed upon the grant of an NSO.  Rather,
at  the time of  exercise of such  NSO, the participant  will recognize ordinary
income for federal income tax purposes in  an amount equal to the excess of  the
fair  market value of  the shares purchased  over the option  price. Zenith will
generally be entitled to  a tax deduction  at such time and  in the same  amount
that the participant recognizes ordinary income.
 
    If shares acquired upon exercise of an NSO are later sold or exchanged, then
the  difference between the sales price and  the fair market value of such stock
on the  date that  ordinary  income was  recognized  with respect  thereto  will
generally  be taxable as  long-term or short-term  capital gain or  loss (if the
stock is a capital  asset of the participant)  depending upon whether the  stock
has been held for more than one year after such date.
 
                                       21
<PAGE>
    According  to  a  published  ruling  of  the  Internal  Revenue  Service,  a
participant who pays the option  price upon exercise of an  NSO, in whole or  in
part,  by delivering shares of Common Stock  already owned by him will recognize
no gain or loss for federal income  tax purposes on the shares surrendered,  but
otherwise  will be taxed according  to the rules described  above for NSOs. With
respect to shares acquired upon exercise which are equal in number to the shares
surrendered, the basis of such shares will  be equal to the basis of the  shares
surrendered,  and the  holding period  of the  shares acquired  will include the
holding period  of  the  shares  surrendered. The  basis  of  additional  shares
received  upon exercise will be equal to the fair market value of such shares on
the date which governs the  determination of the participant's ordinary  income,
and the holding period for such additional shares will commence on such date.
 
RIGHTS
 
    A  grant of SARs or LSARs has no federal income tax consequences at the time
of such grant. Upon the  exercise of SARs or LSARs  (other than a Free  Standing
LSAR),  the amount  of any  cash and  the fair  market value  as of  the date of
exercise of any shares of Common Stock received is taxable to the participant as
ordinary income. With  respect to  a Free  Standing LSAR,  however, a  recipient
should  be  required to  include as  taxable  ordinary income  on the  Change in
Control date an amount equal to the  amount of cash that could be received  upon
the  exercise  of the  LSAR, even  if the  LSAR  is not  exercised until  a date
subsequent to the Change in Control date. Zenith will generally be entitled to a
deduction at the same time and equal to the amount included in the participant's
income. Upon the sale of the shares  acquired by the exercise of SARs or  LSARs,
participants  will recognize capital gain or  loss (assuming such stock was held
as a capital  asset) in an  amount equal  to the difference  between the  amount
realized  upon such sale and the fair market value of the stock on the date that
governs the determination of ordinary income.
 
                               NEW PLAN BENEFITS
 
    The Performance Bonus Committee  has approved a grant  to Mr. Zax under  the
1996  Employee Stock  Option Plan  of options to  purchase a  total of 1,000,000
shares of Common Stock at an option price of $23.6250 per share, which is  equal
to  the average of the high  and low prices of the  Common Stock reported on the
New York Stock Exchange on March 15, 1996. This grant is subject to  stockholder
approval  of the 1996 Employee Stock Option  Plan. No other grants have yet been
made under the 1996 Employee Stock Option Plan.

extent necessary to maintain qualification of  the Plan under Rule 16b-3 of  the

other than Executive Officers  of Zenith and, with  respect to Participants  who
are  Executive Officers of Zenith, by  the Committee (initially, the Performance
Bonus Committee) which shall be appointed by the Board and which shall serve  at
the pleasure of the Board.
 
    Pursuant  to the terms of  the Plan, the Administrator  shall have the power
and authority  to grant  to Eligible  Employees: (a)  Stock Options,  (b)  Stock
Appreciation Rights or Limited Stock Appreciation Rights, or (c) any combination
of the foregoing.
 
    In particular, the Administrator shall have the authority:
 
        (a)  to select those  employees of the Company  and its subsidiaries who
    shall be Participants;
 
        (b) to  determine  whether  and  to what  extent  Stock  Options,  Stock

<PAGE>
        (d)  to determine  the terms and  conditions, not  inconsistent with the
    terms of the Plan, of any award granted hereunder, including the effect,  if

        (e)  to determine  the terms and  conditions, not  inconsistent with the
    terms of the Plan, which shall govern all written instruments evidencing the
    Stock Options, Stock Appreciation Rights, Limited Stock Appreciation  Rights
    or any combination of the foregoing.
 
    The  Administrator shall  have the authority,  in its  discretion, to adopt,
alter and repeal such administrative  rules, guidelines and practices  governing
the  Plan as it shall  from time to time deem  advisable; to interpret the terms
and provisions  of  the Plan  and  any award  issued  under the  Plan  (and  any
agreements  relating thereto); and to  otherwise supervise the administration of
the Plan.
 
    All decisions made by  the Administrator pursuant to  the provisions of  the
Plan  shall be final and  binding on all persons,  including the Company and the
Participants.
 
SECTION 3.  STOCK SUBJECT TO PLAN.
 
    The total number  of shares  of Stock  reserved and  available for  issuance
under  the  Plan shall  be 2,000,000  plus  that number  of shares  reserved and
available for grant pursuant to new  awards under the Zenith National  Insurance
Corp.  Non-Qualified Stock Option Plan (the "Old Stock Option Plan") immediately
prior to the time the  Old Stock Option Plan is  terminated, which time will  be
the  date the Company's stockholders approve  the Plan. Such shares may consist,
in whole or in part, of authorized  and unissued shares or treasury shares.  The
aggregate   number  of  shares  of  Stock  as  to  which  Stock  Options,  Stock
Appreciation Rights and Limited Stock Appreciation Rights may be granted to  any
single individual during any one calendar year may not, subject to adjustment as
provided in this Section 3, exceed 1,000,000.
 
    To the extent that a Stock Option expires or is otherwise terminated without
being exercised, such shares shall again be available for issuance in connection
with  future awards under the Plan. If any  shares of Stock have been pledged as
collateral for indebtedness  incurred by  a Participant in  connection with  the
exercise  of  a Stock  Option and  such shares  are returned  to the  Company in
satisfaction of  such indebtedness,  such shares  shall again  be available  for
issuance  in connection with  future awards under  the Plan. Notwithstanding the
foregoing provisions of this paragraph,  for purposes of determining the  number
of  shares of Stock available for issuance  to persons subject to Section 162(m)
of the Code, such shares shall not again be available for issuance in connection
with future awards to such persons.
 
    In the event of any merger, reorganization, consolidation, recapitalization,
stock dividend or  other change in  corporate structure affecting  the Stock,  a
substitution  or adjustment shall be made in  (i) the aggregate number of shares
reserved for issuance under the Plan and (ii) the kind, number and option  price
of  shares subject  to outstanding  Stock Options  granted under  the Plan. Such
other substitutions or  adjustments shall be  made as may  be determined by  the
Administrator,  in its sole  discretion. An adjusted option  price shall also be
used to determine the  amount payable by  the Company upon  the exercise of  any
Stock Appreciation Right or Limited Stock Appreciation Right associated with any
Stock  Option. In  connection with  any event  described in  this paragraph, the
Board may provide, in  its discretion, for the  cancellation of any  outstanding
awards and payment in cash or other property therefor.
 
SECTION 4.  ELIGIBILITY.
 
    Officers (including officers who are directors of the Company) and employees
of  the Company or any Subsidiary (the "Eligible Employees") who are responsible
for or are in a position to contribute  to the long term success of the  Company
shall  be eligible  to be  granted Stock  Options, Stock  Appreciation Rights or
 
                                      A-3
<PAGE>
Limited Stock Appreciation  Rights hereunder.  The Participants  under the  Plan
shall  be  selected  from  time  to  time  by  the  Administrator,  in  its sole
discretion,  from  among  the  Eligible  Employees  recommended  by  the  senior
management  of the Company,  and the Administrator shall  determine, in its sole
discretion, the number of shares covered by each award.
 
SECTION 5.  STOCK OPTIONS.
 
    Stock Options may be  granted alone or in  addition to other awards  granted
under the Plan. Any Stock Option granted under the Plan shall be in such form as
the  Administrator may from  time to time  approve, and the  provisions of Stock
Option awards need not be the same with respect to each optionee. Recipients  of
Stock  Options shall enter  into a subscription and/or  award agreement with the
Company, in  such form  as the  Administrator shall  determine, which  agreement
shall set forth, among other things, the option price of the option, the term of
the  option  and  provisions  regarding  exercisability  of  the  option granted
thereunder.
 
    The Stock  Options  granted under  the  Plan shall  be  Non-Qualified  Stock
Options.
 
    The  Administrator shall have  the authority to  grant any Eligible Employee
Non-Qualified Stock  Options  (with  or without  Stock  Appreciation  Rights  or
Limited  Stock Appreciation Rights). More than one  option may be granted to the
same optionee and be outstanding concurrently hereunder.
 
    Stock Options granted under the Plan shall be subject to the following terms
and conditions  and shall  contain  such additional  terms and  conditions,  not
inconsistent  with the terms of the Plan, as the Administrator in its discretion
shall deem appropriate:
 
        (1) OPTION PRICE. The option price per share of Stock purchasable  under
    a  Stock  Option  shall  be  determined by  the  Administrator  in  its sole
    discretion at the time of grant but  shall not be less than the Fair  Market
    Value of the Stock on the date such Stock Option is granted.
 
        (2)  OPTION TERM. The  term of each  Stock Option shall  be fixed by the
    Administrator, but no Stock Option shall  be exercisable more than ten  (10)
    years after the date such Stock Option is granted.
 
        (3)  EXERCISABILITY. Stock Options shall be  exercisable at such time or
    times and subject to such terms and conditions as shall be determined by the
    Administrator at  or after  grant.  The Administrator  may provide,  in  its
    discretion, that any Stock Option shall be exercisable only in installments,
    and  the Administrator may waive such installment exercise provisions at any
    time in whole  or in part  based on  such factors as  the Administrator  may
    determine, in its sole discretion.
 
        (4) METHOD OF EXERCISE. Subject to Section 5(3) above, Stock Options may
    be  exercised in whole or  in part at any time  during the option period, by
    giving written notice of  exercise to the Company  specifying the number  of
    shares  to be  purchased, accompanied  by payment  in full  of the aggregate
    option price by delivery of (i) cash or cash equivalents (as approved by the
    Administrator), (ii) previously  acquired shares  of Common  Stock having  a
    Fair  Market Value  on the  date of  payment equal  to the  aggregate option
    price, (iii)  an executed  irrevocable exercise  notice to  the Company  and
    irrevocable  instructions to a broker-dealer to sell a sufficient portion of
    the optioned shares to pay the  aggregate option price and deliver the  sale
    proceeds  directly to the Company (as  approved by the Administrator) or any
    other cashless exercise procedure approved by the Administrator, or (iv) any
    combination of (i),  (ii) and  (iii) such that  the sum  thereof equals  the
    aggregate  option  price. An  optionee shall  generally  have the  rights to
    dividends  and   any   other   rights  of   a   stockholder   with   respect
 
                                      A-4
<PAGE>
    to the Stock subject to the option only after the optionee has given written
    notice of exercise, has paid in full for such shares, and, if requested, has
    given the representation described in paragraph (1) of Section 9.
 
        The  Administrator  may  require the  voluntary  surrender of  all  or a
    portion of any Stock Option granted under the Plan as a condition  precedent
    to  the grant of a new Stock Option.  Subject to the provisions of the Plan,
    such new Stock Option shall be exercisable at the price, during such  period
    and on such other terms and conditions as are specified by the Administrator
    at  the time the new Stock Option  is granted; PROVIDED, HOWEVER, should the
    Administrator so require,  the number of  shares subject to  such new  Stock
    Option  shall  not be  greater  than the  number  of shares  subject  to the
    surrendered Stock  Option.  Upon their  surrender,  Stock Options  shall  be
    canceled  and the shares  previously subject to  such canceled Stock Options
    shall again  be available  for  grants of  Stock  Options and  other  awards
    hereunder,  except  as otherwise  provided  herein with  respect  to persons
    subject to Section 162(m) of the Code.
 
        (5) LOANS. The Company may make loans available to Stock Option  holders
    in  connection with  the exercise of  outstanding options  granted under the
    Plan, as the  Administrator, in  its discretion, may  determine. Such  loans
    shall  (i) be evidenced by promissory notes entered into by the Stock Option
    holders in favor of the Company, (ii) be subject to the terms and conditions
    set forth in  this Section  5(5) and such  other terms  and conditions,  not
    inconsistent with the Plan, as the Administrator shall determine, (iii) bear
    interest,  if any,  at such rate  as the Administrator  shall determine, and
    (iv) be subject to  Board approval (or to  approval by the Administrator  to
    the  extent the  Board may  delegate such  authority). In  no event  may the
    principal amount of any such loan exceed the sum of (x) the aggregate option
    price less the aggregate  par value of  the shares of  Stock covered by  the
    option,  or portion thereof,  exercised by the holder,  and (y) any Federal,
    state, and local income tax attributable to such exercise. The initial  term
    of  the loan, the schedule  of payments of principal  and interest under the
    loan, the extent to which the loan is to be with or without recourse against
    the holder with  respect to principal  or interest and  the conditions  upon
    which  the loan will become payable in the event of the holder's termination
    of  employment  shall  be  determined  by  the  Administrator.  Unless   the
    Administrator  determines otherwise,  when a loan  is made,  shares of Stock
    having a Fair Market  Value at least  equal to the  principal amount of  the
    loan  shall be pledged by the holder  to the Company as security for payment
    of the unpaid balance of the loan,  and such pledge shall be evidenced by  a
    pledge   agreement,  the  terms   of  which  shall   be  determined  by  the
    Administrator, in its  discretion; PROVIDED, HOWEVER,  that each loan  shall
    comply  with  all applicable  laws, regulations  and rules  of the  Board of
    Governors of the Federal  Reserve System and  any other governmental  agency
    having jurisdiction.
 
        (6)  NON-TRANSFERABILITY OF OPTIONS. Unless  otherwise determined by the
    Administrator subject to  the limitations  on transferability  set forth  in
    Rule  16b-3, no Stock Option shall be  transferable by the optionee, and all
    Stock Options shall be exercisable, during the optionee's lifetime, only  by
    the optionee.
 
        (7)  TERMINATION BY DEATH.  If an Optionee should  die while employed by
    the Company or any  of its subsidiaries  or within three  (3) months of  the
    termination  of such employment, any Stock  Option held by such optionee may
    thereafter be exercised, to the extent the optionee would have been entitled
    to do so at the  date of death or  the termination of employment  (whichever
    first  occurs)  or  on such  accelerated  basis as  the  Administrator shall
    determine at or after  grant. Such option  may be so  exercised at any  time
    within  one (1)  year from the  date of  such optionee's death  or until the
    expiration of the stated term of
 
                                      A-5
<PAGE>
    such Stock Option, whichever period is shorter, by the optionee's  executors
    or  administrators or by any  person or persons who  shall have acquired the
    Stock Option from the optionee by bequest, inheritance or otherwise.
 
        (8) TERMINATION OTHER  THAN BY  DEATH. In  the event  an optionee  shall
    cease  to be an employee  of the Company or  its subsidiaries for any reason
    other than death,  any Stock Option  held by the  optionee may be  exercised
    within three (3) months from the date of termination of employment (or until
    the  expiration of the stated term of  such Stock Option, if earlier) to the
    extent such Stock Option was exercisable as of the date of such  termination
    of  employment  or  on such  accelerated  basis as  the  Administrator shall
    determine at or after grant.
 
SECTION 6.  STOCK APPRECIATION RIGHTS AND LIMITED STOCK APPRECIATION RIGHTS.
 
    (1)   GRANT AND  EXERCISE.   Stock  Appreciation  Rights and  Limited  Stock
Appreciation  Rights may be granted either  alone ("Free Standing Rights") or in
conjunction with  all  or  part of  any  Stock  Option granted  under  the  Plan
("Related  Rights"). In the case of a Non-Qualified Stock Option, Related Rights
may be granted either at or after the time of the grant of such Stock Option.
 
    A Related Right or applicable portion thereof granted in conjunction with  a
given  Stock  Option  shall terminate  and  no  longer be  exercisable  upon the
termination or  exercise  of  the  related Stock  Option,  except  that,  unless
otherwise  provided by the Administrator  at the time of  grant, a Related Right
granted with respect to less than the full number of shares covered by a related
Stock Option shall  only be  reduced if  and to the  extent that  the number  of
shares  covered  by the  exercise  or termination  of  the related  Stock Option
exceeds the number of shares not covered by the Related Right.
 
    A Related  Right  may  be  exercised by  an  optionee,  in  accordance  with
paragraph  (2) of this Section 6, by  surrendering the applicable portion of the
related Stock Option. Upon  such exercise and surrender,  the optionee shall  be
entitled  to receive an amount determined  in the manner prescribed in paragraph
(2) of this Section 6. Stock Options which have been so surrendered, in whole or
in part, shall no longer  be exercisable to the  extent the Related Rights  have
been so exercised.
 
    (2)   TERMS AND CONDITIONS.   Stock Appreciation Rights  shall be subject to
such terms and conditions, not inconsistent with the provisions of the Plan,  as
shall  be  determined from  time  to time  by  the Administrator,  including the
following:
 
        (a) Stock Appreciation  Rights that are  Related Rights ("Related  Stock
    Appreciation Rights") shall be exercisable only at such time or times and to
    the  extent that the Stock Options to which they relate shall be exercisable
    in accordance with the  provisions of Section  5 and this  Section 6 of  the
    Plan;  PROVIDED, HOWEVER, that no Related  Stock Appreciation Right shall be
    exercisable during  the first  six  months of  its  term, except  that  this
    additional limitation shall not apply in the event of death or disability of
    the optionee prior to the expiration of such six-month period.
 
        (b) Upon the exercise of a Related Stock Appreciation Right, an optionee
    shall  be entitled to receive up to, but not more than, an amount in cash or
    that number of shares of Stock (or in some combination of cash and shares of
    Stock) equal in value to the excess of the Fair Market Value of one share of
    Stock as of the date of exercise  over the option price per share  specified
    in  the related Stock Option multiplied by  the number of shares of Stock in
    respect of which the  Related Stock Appreciation  Right is being  exercised,
    with the Administrator having the right to determine the form of payment.
 
                                      A-6
<PAGE>
        (c)   Related  Stock   Appreciation  Rights  shall   be  exercisable  or
    transferable only when and  to the extent that  the underlying Stock  Option
    would be exercisable or transferable under paragraphs (3) and (6) of Section
    5 of the Plan.
 
        (d)  Upon the exercise of a  Related Stock Appreciation Right, the Stock
    Option or part  thereof to which  such Related Stock  Appreciation Right  is
    related  shall  be deemed  to have  been  exercised for  the purpose  of the
    limitation set forth in  Section 3 of  the Plan on the  number of shares  of
    Stock  to be issued under the Plan,  provided, however, that with respect to
    grants made  to persons  not subject  to Section  162(m) of  the Code,  such
    exercise  shall be deemed to take place for such purposes only to the extent
    of the number of shares issued under the Related Stock Appreciation Right.
 
        (e) Stock  Appreciation  Rights that  are  Free Standing  Rights  ("Free
    Standing  Stock Appreciation Rights")  shall be exercisable  at such time or
    times and subject to such terms and conditions as shall be determined by the
    Administrator at or after  grant; PROVIDED, HOWEVER,  that no Free  Standing
    Stock Appreciation Right shall be exercisable during the first six months of
    its  term, except that this limitation shall not apply in the event of death
    or disability of the recipient of the Free Standing Stock Appreciation Right
    prior to the expiration of such six-month period.
 
        (f) The term  of each Free  Standing Stock Appreciation  Right shall  be
    fixed  by the Administrator,  but no Free  Standing Stock Appreciation Right
    shall be exercisable more than ten (10)  years after the date such right  is
    granted.
 
        (g)  Upon the  exercise of a  Free Standing Stock  Appreciation Right, a
    recipient shall be entitled to receive up  to, but not more than, an  amount
    in  cash or that  number of shares of  Stock (or any  combination of cash or
    shares of Stock) equal in  value to the excess of  the Fair Market Value  of
    one  share of  Stock as  of the date  of exercise  over the  price per share
    specified in the Free Standing  Stock Appreciation Right (which price  shall
    be  no less than 100% of  the Fair Market Value of  the Stock on the date of
    grant) multiplied by the number of shares  of Stock in respect to which  the
    right  is  being  exercised,  with the  Administrator  having  the  right to
    determine the form of payment.
 
        (h) Free  Standing Stock  Appreciation Rights  shall be  exercisable  or
    transferable  only  when and  to the  extent  that a  Stock Option  would be
    exercisable or transferable under paragraphs (3) and (6) of Section 5 of the
    Plan.
 
        (i) In the  event a  Participant who  has received  Free Standing  Stock
    Appreciation  Rights shall  cease to  be an employee  of the  Company or its
    subsidiaries for any reason,  such rights shall be  exercisable to the  same
    extent  that a Stock Option would have been exercisable in the event of such
    termination of employment as set forth in Sections 5(7) and 5(8).
 
        (j) Limited Stock Appreciation Rights  may only be exercised within  the
    30-day   period  following  a  "Change  in   Control"  (as  defined  by  the
    Administrator in the  agreement evidencing such  Limited Stock  Appreciation
    Right)  and,  with respect  to Limited  Stock  Appreciation Rights  that are
    Related Rights ("Related  Limited Stock Appreciation  Rights"), only to  the
    extent  that the Stock Options to which  they relate shall be exercisable in
    accordance with the provisions of Section 5 and this Section 6 of the  Plan;
    PROVIDED, HOWEVER, that no Related Limited Stock Appreciation Right shall be
    exercisable  during  the first  six  months of  its  term, except  that this
    additional limitation shall not apply in the event of death or disability of
    the optionee prior to the expiration of such six-month period.
 
        (k) Upon  the  exercise  of  a Limited  Stock  Appreciation  Right,  the
    recipient  shall be entitled to receive an  amount in cash equal in value to
    the  excess   of   the   "Change   in  Control   Price"   (as   defined   in
 
                                      A-7
<PAGE>
    the agreement evidencing such Limited Stock Appreciation Right) of one share
    of  Stock as  of the date  of exercise over  (A) the option  price per share
    specified in the related Stock Option, or (B) in the case of a Limited Stock
    Appreciation Right which is  a Free Standing  Stock Appreciation Right,  the
    price  per share  specified in the  Free Standing  Stock Appreciation Right,
    such excess to be multiplied by the number of shares in respect of which the
    Limited Stock Appreciation Right shall have been exercised.
 
SECTION 7.  AMENDMENT AND TERMINATION.
 
    The Board  may amend,  alter  or discontinue  the  Plan, but  no  amendment,
alteration,  or discontinuation shall be made that  would impair the rights of a
Participant under  any  award  theretofore granted  without  such  Participant's
consent,  or that without the approval  of the stockholders (as described below)
would:
 
        (1) except as provided in Section 3, increase the total number of shares
    of Stock reserved for the purpose of the Plan;
 
        (2) change the class of  officers and employees eligible to  participate
    in the Plan; or
 
        (3) extend the maximum option period under paragraph (2) of Section 5 of
    the Plan.
 
    Notwithstanding  the foregoing,  stockholder approval  under this  Section 8
shall only be required at such time and under such circumstances as  stockholder
approval  would be required under Rule 16b-3  of the Exchange Act and/or Section
162(m) of  the Code  with respect  to  any material  amendment to  any  employee
benefit plan of the Company.
 
    The  Administrator may  amend the  terms of  any award  theretofore granted,
prospectively or  retroactively,  but,  subject  to Section  3  above,  no  such
amendment shall impair the rights of any holder without his or her consent.
 
SECTION 8.  UNFUNDED STATUS OF PLAN.
 
    The  Plan  is  intended  to  constitute  an  "unfunded"  plan  for incentive
compensation. With respect to any payments not yet made to a Participant by  the
Company,  nothing contained  herein shall give  any such  Participant any rights
that are greater than those of a general creditor of the Company.
 
SECTION 9.  GENERAL PROVISIONS.
 
        (1) The Administrator may require each person purchasing shares pursuant
    to a Stock Option to represent to and agree with the Company in writing that
    such person is acquiring the shares without a view to distribution  thereof.
    The   certificates  for  such  shares  may  include  any  legend  which  the
    Administrator deems appropriate to reflect any restrictions on transfer. All
    certificates for shares of Stock delivered  under the Plan shall be  subject
    to  such stock-transfer orders  and other restrictions  as the Administrator
    may deem advisable under the  rules, regulations, and other requirements  of
    the  Commission, any stock exchange upon which the Stock is then listed, and
    any applicable federal or  state securities law,  and the Administrator  may
    cause  a legend  or legends to  be placed  on any such  certificates to make
    appropriate reference to such restrictions.
 
        (2) Nothing contained in the Plan shall prevent the Board from  adopting
    other  or  additional  compensation  arrangements,  subject  to  stockholder
    approval if such approval is required;  and such arrangements may be  either
    generally  applicable or applicable only in  specific cases. The adoption of
    the Plan shall not confer upon any officer or other employee of the  Company
    any  right to continued employment with the Company, as the case may be, nor
    shall it interfere in any way with the right of the Company to terminate the
    employment of any of its officers or employees at any time.
 
                                      A-8
<PAGE>
        (3) Each Participant shall, no later than the date as of which the value
    of an award first becomes includible in the gross income of the  Participant
    for  federal income tax  purposes, pay to the  Company, or make arrangements
    satisfactory to the Administrator regarding payment of, any federal,  state,
    or  local taxes of any  kind required by law to  be withheld with respect to
    the  award.  The  obligations  of  the  Company  under  the  Plan  shall  be
    conditional  on the making of such payments or arrangements, and the Company
    shall, to the extent  permitted by law,  have the right  to deduct any  such
    taxes from any payment of any kind otherwise due to the Participant.
 
        (4)  No member  of the  Board or the  Administrator, nor  any officer or
    employee of the Company acting on behalf of the Board or the  Administrator,
    shall  be personally liable for any action, determination, or interpretation
    taken or made in good faith with respect to the Plan, and all members of the
    Board or  the Administrator  and each  and any  officer or  employee of  the
    Company  acting on their  behalf shall, to  the extent permitted  by law, be
    fully indemnified  and protected  by  the Company  in  respect of  any  such
    action, determination or interpretation.
 
SECTION 10.  EFFECTIVE DATE OF PLAN.
 
    The  Plan became effective (the "Effective Date") on March 7, 1996, the date
the Board of Directors  formally approved the Plan,  as amended March 15,  1996,
subject  to the approval of the  stockholders of the Corporation, which approval
was obtained on [             ].
 
SECTION 11.  TERM OF PLAN.
 
    No Stock  Option, Stock  Appreciation Right  or Limited  Stock  Appreciation
Right shall be granted pursuant to the Plan on or after the tenth anniversary of
the  date on  which the stockholders  approved the Plan,  but awards theretofore
granted may extend beyond that date.
