                          AGREEMENT AND PLAN OF MERGER

     AGREEMENT  AND PLAN OF MERGER,  dated as of  February  15,  1999,  among XL
CAPITAL LTD, a limited liability  company  organized and incorporated  under the
laws of the Cayman  Islands  ("Parent"),  DASHER  ACQUISITION  CORP., a Delaware
corporation and a direct wholly owned  subsidiary of Parent ("Sub"),  and NAC RE
CORP., a Delaware corporation (the "Company").

     WHEREAS,  the respective Boards of Directors of Parent, Sub and the Company
have  determined  that it is  advisable  and  would  be fair to and in the  best
interests of their respective  stockholders to consummate the merger of Sub with
and into  the  Company  (the  "Merger"),  upon  the  terms  and  subject  to the
conditions set forth herein;

     WHEREAS, concurrently with the execution and delivery of this Agreement and
as a  condition  and  inducement  to  Parent's  willingness  to enter  into this
Agreement, the Company has entered into a stock option agreement dated as of the
date of this  Agreement  and  attached  hereto as Exhibit A (the  "Stock  Option
Agreement"),  pursuant to which the Company granted Parent an option to purchase
shares of common stock, par value $0.10 per share, of the Company, together with
the associated  purchase rights (the "Company  Rights") under the Company Rights
Agreement (as defined in Section 3.24(a)) ("Company Common Stock") under certain
circumstances;

     WHEREAS,  Parent,  Sub and the Company  intend that the Merger be accounted
for as a  pooling-of-interests  for financial  statement  purposes  under United
States generally accepted accounting principles;

     WHEREAS,  Parent,  Sub and the Company intend that the Merger shall qualify
as a  tax-free  reorganization  within  the  meaning  of  Section  368(a) of the
Internal  Revenue  Code of 1986,  as  amended  (the  "Code"),  and the rules and
regulations promulgated thereunder;

     WHEREAS,   Parent,   Sub   and  the   Company   desire   to  make   certain
representations,  warranties,  covenants and  agreements in connection  with the
transactions contemplated hereby and also to prescribe various conditions to the
transactions contemplated hereby;

     WHEREAS,   the  Board  of   Directors  of  the  Company  has  approved  the
transactions  contemplated  by this Agreement and the Stock Option  Agreement in
accordance  with  the  provisions  of  Section  203  of  the  Delaware   General
Corporation Law (the "DGCL"); and

     WHEREAS,  certain  capitalized terms used but not defined herein shall have
the meanings set forth in Section 8.14.

     NOW,  THEREFORE,  in  consideration  of the  foregoing  and the  respective
representations,  warranties,  covenants and  agreements set forth herein and in
the Stock Option Agreement, the parties hereto agree as follows:

                                    ARTICLE I

                                   THE MERGER

     Section 1.1 The Merger.  Upon the terms and  subject to the  conditions  of
this  Agreement,  and in accordance  with the DGCL,  at the  Effective  Time (as
defined in Section  1.2),  Sub shall be merged with and into the  Company.  As a
result of the Merger,  the separate  corporate  existence of Sub shall cease and
the Company  shall  continue  as the  surviving  corporation  of the Merger (the
"Surviving Corporation").

     Section 1.2  Effective  Time.  Subject to the terms and  conditions of this
Agreement,  the  parties  hereto  shall  cause the Merger to be  consummated  by
filing, as soon as practicable after the Closing (as hereinafter defined),  this
Agreement or a  certificate  of merger (the  "Certificate  of Merger")  with the
Secretary  of State of the State of  Delaware,  in such form as required by, and
executed in accordance  with the relevant  provisions of, the DGCL. The date and
time of the filing of the  Certificate  of Merger with the Secretary of State of
the State of  Delaware  (or such  later time as shall be agreed to in writing by
the parties  hereto and  specified  in the  Certificate  of Merger)  will be the
"Effective  Time". The closing of the Merger (the "Closing") shall take place at
10:00  a.m.  (New  York  City  time)  on  the  second  business  day  after  the
Determination Date (as defined in Section 7.1(g)), unless the Board of Directors
of the Company shall have  delivered  notice to Parent of its  determination  to
exercise its termination  right as set forth therein,  in which case the Closing
shall take place on the tenth day following the Determination  Date (or, if such
day is not a business day, on the next  succeeding  business  day),  unless this
Agreement has been  theretofore  terminated in accordance with its terms, at the
offices of Simpson Thacher & Bartlett,  425 Lexington Avenue, New York, New York
10017, or such other time, date and place as the parties shall agree.

     Section 1.3 Effects of the  Merger.  The Merger  shall have the effects set
forth in the applicable  provisions of the DGCL. Without limiting the generality
of the foregoing,  and subject thereto,  at the Effective Time all the property,
rights,  privileges,  immunities,  powers and  franchises of the Company and Sub
shall vest in the Surviving Corporation,  and all debts,  liabilities and duties
of the Company  and Sub shall  become the debts,  liabilities  and duties of the
Surviving Corporation.

     Section 1.4  Certificate of  Incorporation;  By-laws.  (a) At the Effective
Time and  without  any  further  action on the part of the  Company or Sub,  the
certificate of  incorporation of the Company as in effect  immediately  prior to
the Effective Time shall be the  certificate of  incorporation  of the Surviving
Corporation  until  thereafter  amended as provided  therein and under the DGCL,
except that at the  Effective  Time such  certificate  of  incorporation  of the
Company shall be amended as follows: (i) Article FOURTH shall be amended to read
in its  entirety  as  follows:  "The total  number of shares of stock  which the
Corporation  shall  have  authority  to issue is 1,000  shares,  which  shall be
designated  Common  Stock with a par value of $0.10 per  share.";  (ii)  Article
FIFTH shall be deleted in its entirety; and (iii) Article TENTH shall be deleted
in its entirety.

     (b) At the Effective Time and without any further action on the part of the
Company  or Sub,  the  by-laws  of Sub  shall be the  by-laws  of the  Surviving
Corporation  and thereafter may be amended or repealed in accordance  with their
terms  or the  terms  of  the  certificate  of  incorporation  of the  Surviving
Corporation and as provided by law.

     Section 1.5 Directors and Officers.  The directors of Sub immediately prior
to the Effective Time,  together with any directors of the Company  specified by
Parent  prior to the  Effective  Time,  shall be the  initial  directors  of the
Surviving Corporation, each to hold office in accordance with the certificate of
incorporation and by-laws of the Surviving Corporation,  and the officers of the
Company immediately prior to the Effective Time shall be the initial officers of
the Surviving  Corporation,  in each case until their respective  successors are
duly elected or appointed (as the case may be) and qualified.

     Section 1.6 Effect on Capital Stock.  (a) At the Effective  Time, by virtue
of the Merger and without any action on the part of the  holders  thereof,  each
share of Company Common Stock issued and  outstanding  immediately  prior to the
Effective  Time shall be converted into the right to receive .915 (the "Exchange
Ratio")  of a Class A  Ordinary  Share,  par value  $0.01 per  share,  of Parent
("Parent Ordinary  Shares"),  together with the associated  purchase rights (the
"Parent  Rights") under the Parent Rights  Agreement (as defined in Section 4.2)
(which together with any cash in lieu of fractional  Parent Ordinary Shares paid
pursuant  to  Section  2.5  shall be the  "Merger  Consideration").  All  Parent
Ordinary Shares issued as Merger  Consideration  shall be validly issued,  fully
paid and non-assessable.  Subject to the terms and conditions of this Agreement,
Parent shall take such action as shall be necessary to issue the Parent Ordinary
Shares to be received as Merger Consideration and cause them to be registered on
its  share  register  in the  names  of the  holders  of  Company  Common  Stock
submitting  Certificates (as defined in Section 1.6(b)) in exchange  therefor in
accordance with the terms hereof.

     (b) As a result of the  Merger  and  without  any action on the part of the
holders thereof, at the Effective Time, all shares of Company Common Stock shall
cease to be  outstanding  and shall be  canceled  and retired and shall cease to
exist,  and  each  holder  (other  than  Parent,  Sub  and  the  Company  ) of a
certificate which, immediately prior to the Effective Time, represented any such
shares of Company Common Stock (a "Certificate")  shall thereafter cease to have
any rights with respect to such shares of Company Common Stock, except the right
to receive the applicable  Merger  Consideration  in accordance  with Article II
upon the surrender of such Certificate.

     (c) Each share of Company  Common Stock issued and owned or held by Parent,
Sub or the Company at the Effective Time shall,  by virtue of the Merger,  cease
to be  outstanding  and shall be canceled  and  retired  and no Parent  Ordinary
Shares or other consideration shall be delivered in exchange therefor.

     (d) Each share of common  stock,  par value  $0.01 per share,  of Sub ("Sub
Common Stock") issued and  outstanding  immediately  prior to the Effective Time
shall be  converted  into and shall  become one validly  issued,  fully paid and
nonassessable share of common stock, par value $0.01 per share, of the Surviving
Corporation ("Surviving Corporation Common Stock") as of the Effective Time, and
the  Surviving  Corporation  shall  become a wholly  owned  direct  or  indirect
subsidiary of Parent.

     (e) At the Effective Time, each  outstanding  option to purchase,  right to
receive or other equity  grant whose value is derived from Company  Common Stock
(a "Company Stock Option")  issued  pursuant to the (i) NAC Re Corp.  1989 Stock
Option Plan, (ii) NAC Re Corp.  1993 Stock Option Plan,  (iii) NAC Re Corp. 1997
Incentive and Capital  Accumulation Plan, (iv) Amended and Restated NAC Re Corp.
Employee  Stock  Purchase  Plan (the  "Stock  Purchase  Plan"),  (v) Amended and
Restated  Directors  Stock Option Plan and (vi) the NAC Re United Kingdom Option
Scheme  (collectively,  the "Company Stock Plans"),  whether vested or unvested,
shall be  deemed to  constitute  an option  to  acquire,  on the same  terms and
conditions  as were  applicable  under such Company  Stock  Option  (taking into
account any  acceleration of vesting as a result of the Merger),  that number of
Parent  Ordinary Shares which the holder of such Company Stock Option would have
been  entitled to receive  pursuant  to the Merger if such holder had  exercised
such  Company  Stock  Option in full  immediately  prior to the  Effective  Time
(rounded down to the nearest whole share),  at an exercise price per share equal
to (y) the  exercise  price per share for the  shares of  Company  Common  Stock
purchasable  pursuant to such Company  Stock Option  divided by (z) the Exchange
Ratio,  rounded  upwards  to the  nearest  whole  cent (a  "Converted  Option").
Notwithstanding the foregoing, in the case of any Company Stock Options to which
Section 421 of the Code applies by reason of their  qualification  under Section
422 or 423 of the Code, the option price,  the number of Parent  Ordinary Shares
purchasable  upon  exercise  of such  Company  Stock  Option  and the  terms and
conditions  of  exercise  thereof  shall be  determined  in order to comply with
Section 424(a) of the Code.  Parent shall take such actions as are necessary for
the  assumption of the Company Stock  Options  pursuant to this Section  1.6(e),
including the reservation, issuance and listing of Parent Ordinary Shares as are
necessary to effectuate the  transactions  contemplated  by this Section 1.6(e).
Parent  shall  promptly  prepare  and file  with  the  Securities  and  Exchange
Commission (the "SEC") a registration statement on Form S-8 or other appropriate
form with respect to Parent  Ordinary  Shares  subject to Company  Stock Options
issued  under such  Company  Stock Plans and shall use its best  efforts to have
such  registration   statement  declared  effective  immediately  following  the
Effective Time and to maintain the effectiveness of such registration  statement
or  registration  statements  covering the Parent  Ordinary Shares issuable upon
exercise of such Company Stock  Options (and maintain the current  status of the
prospectus or prospectuses  contained therein) for so long as such Company Stock
Options remain outstanding.


                                   ARTICLE II

                            EXCHANGE OF CERTIFICATES

     Section 2.1  Exchange  Fund.  Prior to the  Effective  Time,  Parent  shall
appoint a commercial bank or trust company reasonably acceptable to the Company,
having  net  capital of not less than  $100,000,000,  to act as  exchange  agent
hereunder   for  the  purpose  of   exchanging   Certificates   for  the  Merger
Consideration (the "Exchange Agent").  At or prior to the Effective Time, Parent
shall  deposit with the Exchange  Agent,  in trust for the benefit of holders of
shares of Company Common Stock,  certificates  representing  the Parent Ordinary
Shares (and the associated Parent Rights) issuable pursuant to Section 1.6(a) in
exchange for outstanding  shares of Company Common Stock.  Parent agrees to make
available to the Exchange Agent, from time to time as needed, cash sufficient to
pay cash in lieu of fractional  shares pursuant to Section 2.5 and any dividends
and other  distributions  pursuant  to Section  2.3.  Any cash and  certificates
representing Parent Ordinary Shares (and the associated Parent Rights) deposited
with the Exchange Agent shall hereinafter be referred to as the "Exchange Fund."

     Section 2.2 Exchange Procedures.  Promptly after the Effective Time, Parent
shall cause the  Exchange  Agent to mail to each holder of a  Certificate  (i) a
letter of transmittal  which shall specify that delivery shall be effected,  and
risk of loss and title to the Certificates shall pass, only upon due delivery of
the Certificates  and other required  documents to the Exchange Agent, and which
letter shall be in customary  form and have such other  provisions as Parent may
reasonably  specify (ii) and  instructions  for  effecting the surrender of such
Certificates in exchange for the applicable Merger Consideration. Upon surrender
of a Certificate to the Exchange Agent together with such letter of transmittal,
duly executed and completed in accordance  with the  instructions  thereto,  and
such other  documents as may reasonably be required by the Exchange  Agent,  the
holder of such Certificate shall be entitled to receive in exchange therefor (A)
a  certificate  representing  one  or  more  Parent  Ordinary  Shares  (and  the
associated Parent Rights)  representing,  in the aggregate,  the whole number of
shares  that such  holder has the right to receive  pursuant  to Section  1.6(a)
(after taking into account all shares of Company  Common Stock then held by such
holder) and (B) a check in the amount  (after  giving effect to any required tax
withholdings)  equal to the cash  that  such  holder  has the  right to  receive
pursuant to the  provisions  of this Article II,  including  cash in lieu of any
fractional  Parent  Ordinary  Shares  pursuant  to  Section  2.5 and any  unpaid
dividends and other  distributions to which such holder is entitled  pursuant to
Section 2.3, and the Certificate so surrendered shall forthwith be canceled.  No
interest will be paid or will accrue on any cash payable pursuant to Section 2.3
or Section 2.5. In the event of a transfer of ownership of Company  Common Stock
which is not  registered  in the  transfer  records of the Company  prior to the
Effective  Time, one or more  certificates  evidencing,  in the  aggregate,  the
proper number of Parent Ordinary Shares and a check in the proper amount of cash
in lieu of any fractional Parent Ordinary Shares pursuant to Section 2.5 and any
dividends or other  distributions  to which such holder is entitled  pursuant to
Section 2.3 may be issued with  respect to such  Company  Common Stock to such a
transferee if the Certificate  representing  such shares of Company Common Stock
is presented to the Exchange  Agent,  accompanied  by all documents  required to
evidence and effect such  transfer  and the  ownership of such shares of Company
Common  Stock by such  transferee  and to  evidence  that any  applicable  stock
transfer taxes have been paid.

     Section 2.3 Distributions  with Respect to Unexchanged  Stock. No dividends
or other  distributions  declared or made with respect to Parent Ordinary Shares
with a record date after the  Effective  Time shall be paid to the holder of any
unsurrendered  Certificate  with respect to the Parent Ordinary Shares that such
holder would be entitled to receive upon surrender of such Certificate  pursuant
to the Merger and no cash payment in lieu of fractional  Parent  Ordinary Shares
shall be paid to any such holder pursuant to Section 2.5 until such holder shall
surrender such Certificate in accordance with Section 2.2. Subject to the effect
of applicable law, following  surrender of any such Certificate,  there shall be
paid to such  holder,  without  interest,  (a)  promptly  after the time of such
surrender,  the amount of any cash payable in lieu of fractional Parent Ordinary
Shares to which such holder is  entitled  pursuant to Section 2.5 and the amount
of dividends or other  distributions with a record date after the Effective Time
theretofore paid with respect to such whole Parent Ordinary  Shares,  and (b) at
the  appropriate  payment date,  the amount of dividends or other  distributions
with a record date after the  Effective  Time but prior to such  surrender and a
payment date  subsequent to such  surrender  payable with respect to such Parent
Ordinary Shares.

     Section 2.4 No Further Ownership Rights in Company Common Stock. All Parent
Ordinary Shares issued and cash paid upon conversion of shares of Company Common
Stock in  accordance  with the terms of Article I and this Article II (including
any stock  dividends or cash paid  pursuant to Section 2.3 or cash paid pursuant
to  Section  2.5)  shall be issued or paid in full  satisfaction  of all  rights
pertaining to the shares of Company Common Stock.

     Section 2.5 No Fractional  Parent Ordinary  Shares.  (a) No certificates or
scrip  representing  fractional  Parent Ordinary Shares shall be issued upon the
surrender for exchange of Certificates  and such fractional share interests will
not  entitle  the  owner  thereof  to vote or to have any  rights of a holder of
Parent Ordinary Shares.

     (b) Notwithstanding  any other provision of this Agreement,  each holder of
shares of  Company  Common  Stock  exchanged  pursuant  to the  Merger who would
otherwise  have been entitled to receive a fraction of a Parent  Ordinary  Share
(after taking into account all  Certificates  delivered by such holder) shall be
entitled to receive, in lieu thereof, cash (without interest) in an amount equal
to the product of (i) such  fractional  part of a Parent Ordinary Share and (ii)
the average  closing price of the Parent  Ordinary  Shares on the New York Stock
Exchange,  Inc. (the "NYSE"),  as reported on the NYSE Composite Tape for the 20
trading days prior to and ending on the trading day  immediately  preceding  the
Closing  Date (the  "Average  Price").  As  promptly  as  practicable  after the
determination of the amount of cash, if any, to be paid to holders of fractional
interests,  the Exchange Agent shall so notify Parent,  and Parent shall deposit
such  amount  with the  Exchange  Agent and shall  cause the  Exchange  Agent to
forward  payments  to such  holders of  fractional  interests  subject to and in
accordance with the terms hereof.

     Section 2.6  Termination of Exchange Fund. Any portion of the Exchange Fund
which remains  undistributed  to the holders of Certificates for 12 months after
the Effective Time shall be delivered to Parent or otherwise on the  instruction
of Parent, and any holders of the Certificates who have not theretofore complied
with  this  Article  II shall  thereafter  look only to  Parent  for the  Merger
Consideration  with  respect  to the  shares of Company  Common  Stock  formerly
represented  thereby to which such holders are entitled  pursuant to Section 1.7
and Section 2.2, including any cash in lieu of fractional Parent Ordinary Shares
to which such holders are entitled pursuant to Section 2.5, and any dividends or
distributions  with respect to Parent  Ordinary Shares to which such holders are
entitled  pursuant to Section 2.3, in each case,  without any interest  thereon.
Any such portion of the Exchange Fund  remaining  unclaimed by holders of shares
of Company  Common Stock  immediately  prior to such time as such amounts  would
otherwise  escheat to or become property of any Governmental  Entity (as defined
in Section 3.4) shall,  to the extent  permitted by applicable  law,  become the
property  of Parent  free and  clear of any  claims or  interest  of any  person
previously entitled thereto.

     Section 2.7 No Liability.  None of Parent, Sub, the Company,  the Surviving
Corporation  or the  Exchange  Agent shall be liable to any person in respect of
any  Merger  Consideration  or  any  cash  in  respect  of  dividends  or  other
distributions  from the Exchange Fund delivered to a public official pursuant to
any applicable abandoned property, escheat or similar law.

     Section 2.8  Investment  of the Exchange  Fund.  The  Exchange  Agent shall
invest any cash  included in the Exchange  Fund as directed by Parent on a daily
basis.  Any interest  and other income  resulting  from such  investments  shall
promptly be paid to Parent.

     Section 2.9 Lost  Certificates.  If any  Certificate  shall have been lost,
stolen or destroyed,  upon the making of an affidavit of that fact by the person
claiming such  Certificate to be lost,  stolen or destroyed,  and if required by
Parent, the posting by such person of a bond in such reasonable amount as Parent
may  direct as  indemnity  against  any claim  that may be made  against it with
respect to such  Certificate,  the  Exchange  Agent will deliver in exchange for
such lost, stolen or destroyed Certificate the Merger Consideration with respect
to the shares of Company Common Stock formerly  represented  thereby  (including
any cash in lieu of fractional Parent Ordinary Shares), and any unpaid dividends
and  distributions  on Parent  Ordinary Shares  deliverable in respect  thereof,
pursuant to this Agreement.

     Section 2.10  Withholding  Rights.  Each of the Surviving  Corporation  and
Parent shall be entitled to deduct and withhold from the consideration otherwise
payable  pursuant to this  Agreement  to any holder of shares of Company  Common
Stock such amounts as it is required to deduct and withhold  with respect to the
making of such payment under the Code and the rules and regulations  promulgated
thereunder, or any other provision of applicable law. To the extent that amounts
are so withheld by the Surviving Corporation or Parent, as the case may be, such
withheld  amounts shall be treated for all purposes of this  Agreement as having
been paid to the  holder of the  shares of  Company  Common  Stock in respect of
which such deduction and  withholding  was made by the Surviving  Corporation or
Parent, as the case may be.

     Section 2.11  Further  Assurances.  At and after the  Effective  Time,  the
officers and  directors  of the  Surviving  Corporation  will be  authorized  to
execute and deliver, in the name and on behalf of the Company or Sub, any deeds,
bills of sale,  assignments or assurances and to take and do, in the name and on
behalf of the Company or Sub, any other  actions and things to vest,  perfect or
confirm of record or otherwise in Parent or in the Surviving Corporation any and
all right, title and interest in, to and under any of the rights,  properties or
assets  acquired or to be acquired by Parent or the Surviving  Corporation  as a
result of, or in connection with, the Merger.

     Section  2.12  Stock  Transfer  Books.  At the  Effective  Time,  the stock
transfer  books of the  Company  shall be closed  and there  shall be no further
registration  of transfers of shares of Company  Common Stock  thereafter on the
records  of the  Company.  From and after the  Effective  Time,  the  holders of
Certificates  shall  cease to have any  rights  with  respect  to the  shares of
Company Common Stock formerly represented  thereby,  except the right to receive
the Merger  Consideration and as otherwise provided herein.  Subject to Sections
2.6 and 2.7, on or after the Effective Time, any  Certificates  presented to the
Exchange  Agent or Parent  for any  reason  shall be  converted  into the Merger
Consideration  with  respect  to the  shares of Company  Common  Stock  formerly
represented  thereby  (including any cash in lieu of fractional  Parent Ordinary
Shares to which the holders  thereof are  entitled  pursuant to Section 2.5) and
shall represent the right to receive  dividends or other  distributions to which
the holders thereof are entitled pursuant to Section 2.3.

     Section 2.13 Certain  Adjustments.  If,  between the date of this Agreement
and the Effective Time, the  outstanding  Parent Ordinary Shares shall have been
changed into a different  number of shares or different class of stock by reason
of any reclassification, recapitalization, stock split, split-up, combination or
exchange  of  shares,  or a stock  dividend  or  dividend  payable  in any other
securities  shall be declared  with a record date  within  such  period,  or any
similar event shall have  occurred,  the Exchange  Ratio shall be  appropriately
adjusted  to  provide  the  holders of Company  Common  Stock the same  economic
effect,  voting rights and other terms and  designations as contemplated by this
Agreement prior to any such event.


                                   ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

           The Company hereby represents and warrants to Parent that:

     Section 3.1 Corporation; Organization.

     (a) Each of the  Company and its  subsidiaries  is a  corporation  or other
business  organization  duly  organized,  validly  existing and in good standing
under the laws of the jurisdiction of its incorporation or organization. Each of
the Company and its subsidiaries  (i) is qualified,  licensed or domesticated in
all jurisdictions where such qualification, license or domestication is required
to own and operate its  properties and conduct its business in the manner and at
the places presently  conducted;  (ii) holds all franchises,  grants,  licenses,
certificates,  permits,  consents and orders, all of which are valid and in full
force and effect,  from all  applicable  United  States and  foreign  regulatory
authorities  necessary  to own and  operate  its  properties  and to conduct its
business in the manner and at the places presently conducted; and (iii) has full
power and  authority  (corporate  and  other)  to own,  lease  and  operate  its
respective  properties  and assets  and to carry on its  business  as  presently
conducted  and as proposed to be  conducted,  except  where the failure to be so
qualified,  licensed  or  domesticated,  or to  hold  such  franchises,  grants,
licenses,  certificates,  permits, consents and orders or to have such power and
authority  would  not,  when  taken  together  with  all  other  such  failures,
reasonably  be expected to have a Material  Adverse  Effect with  respect to the
Company.  The Company has furnished to Parent complete and correct copies of its
certificate of incorporation  and by-laws as in effect on the date hereof.  Such
certificate  of  incorporation  and  by-laws are in full force and effect and no
other  organizational  documents are  applicable to or binding upon the Company.
When used in  connection  with any person or any of its  subsidiaries,  the term
"Material Adverse Effect" means any change or effect that,  either  individually
or in the aggregate with all other changes or effects, (i) is materially adverse
to  the  business,   operations,   assets,   liabilities  (including  contingent
liabilities),  financial  condition or results of  operations of such person and
its  subsidiaries  taken as a whole,  or (ii) could  reasonably  be  expected to
materially  impair the  ability of such person to  consummate  the Merger and to
perform its other obligations  hereunder and under the Stock Option Agreement on
a timely basis.

     (b) Section  3.1(b) of the letter,  dated as of the date  hereof,  from the
Company to Parent  regarding  certain  matters  related to this  Agreement  (the
"Company Disclosure Letter"), sets forth the name of each material subsidiary of
the  Company,  the  jurisdiction  of  its  incorporation  and  whether  it is an
insurance company (such insurance companies collectively, the "Company Insurance
Subsidiaries").  None of the  Company  Insurance  Subsidiaries  is  deemed to be
"commercially  domiciled"  in any  other  jurisdiction  other  than as set forth
therein.  Each of the Company  Insurance  Subsidiaries  is (i) duly  licensed or
authorized  as an  insurance  company or, where  applicable,  a reinsurer in its
jurisdiction of incorporation,  (ii) duly licensed or authorized as an insurance
company or, where applicable, a reinsurer in each other jurisdiction where it is
required to be so  licensed or  authorized  (which  jurisdictions  are listed in
Section 3.1(b) of the Company Disclosure  Letter),  and (iii) duly authorized in
its  jurisdiction of  incorporation  and each other  applicable  jurisdiction to
write each line of business  currently  written by it, except, in any such case,
where the failure to be so licensed or authorized would not,  individually or in
the  aggregate,  reasonably be expected to have a Material  Adverse  Effect with
respect to the  Company.  Except as set forth in Section  3.1(b) of the  Company
Disclosure  Letter,  there is no proceeding or investigation  pending or, to the
knowledge  of  the  Company,  threatened  which  would,  individually  or in the
aggregate, reasonably be expected to lead to the revocation,  amendment, failure
to renew, limitation,  suspension or restriction of any such license to transact
insurance  business.  The Company has made all required filings under applicable
insurance  holding  company  statutes  except where the failure to so file would
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect with respect to the Company.

     Section 3.2 Capital  Structure.  (a) The  authorized  capital  stock of the
Company  consists of  25,000,000  shares of Company  Common Stock and  1,000,000
shares of preferred stock, par value $1.00 per share ("Preferred  Stock"). As of
the date hereof,  (i) 18,417,966  shares of Company Common Stock were issued and
outstanding,  (ii)  3,617,064  shares of Company  Common  Stock were held in the
treasury of the  Company,  (iii)  options to acquire an  aggregate  of 2,619,515
shares of  Company  Common  Stock were  outstanding  pursuant  to Company  Stock
Options, including stock appreciation rights, performance units and stock units,
(iv) 49,703 shares of Company  Common Stock were reserved for issuance under the
Stock  Purchase  Plan,  (v)  no  shares  of  preferred  stock  were  issued  and
outstanding  and (vi)  277,500  shares of Series A Junior  Preferred  Stock were
authorized  and reserved for issuance  upon the exercise of the Company  Rights.
All the outstanding  shares of the Company's  capital stock are duly authorized,
validly issued,  fully paid and  non-assessable.  Except as set forth in Section
3.2(a) of the Company Disclosure Letter, there are no bonds,  debentures,  notes
or other indebtedness  having voting rights (or convertible or exchangeable into
securities  having  such  rights)  ("Voting  Debt") of the Company or any of its
subsidiaries  issued and outstanding.  Section 3.2(a) of the Company  Disclosure
Letter sets forth, with respect to each plan, arrangement or agreement set forth
in Section 3.8(a) of the Company  Disclosure Letter pursuant to which options or
stock  appreciation  rights may be granted or under which such  options or stock
appreciation  rights have been granted and are outstanding,  in the aggregate by
plan,  arrangement  or  agreement  the number of options and stock  appreciation
rights  outstanding,  their grant  price,  the date such  options or rights were
granted and the number of shares of Company  Common Stock  reserved for issuance
pursuant to the plan,  arrangement  or agreement  (such options and rights being
herein collectively referred to as the "Company Options"),  a description of the
exercise or purchase prices, vesting schedules,  expiration dates and numbers of
shares of Company  Common Stock  subject to each such Company  Option,  together
with a listing of all  Company  Options  which by their terms shall vest and the
time  at  which  they  will  vest  as a  result  of the  Merger  and  the  other
transactions  contemplated  hereby.  Except as set forth above,  as set forth in
Section 3.2(a) of the Company  Disclosure Letter, for the Company Rights and for
the transactions  contemplated by this Agreement and the Stock Option Agreement,
(i) there are no shares of capital  stock of the Company  authorized,  issued or
outstanding  and (ii)  there  are no  existing  (A)  options,  warrants,  calls,
preemptive  rights,  subscriptions or other rights,  convertible or exchangeable
securities,  agreements,  arrangements or commitments of any character, relating
to  the  issued  or  unissued  capital  stock  of  the  Company  or  any  of its
subsidiaries,  obligating  the  Company  or any of its  subsidiaries  to  issue,
transfer  or sell or cause to be  issued,  transferred  or sold  any  shares  of
capital stock or Voting Debt of, or other equity interest in, the Company or any
of its  subsidiaries,  (B) securities  convertible into or exchangeable for such
shares or equity  interests  or (C)  obligations  of the  Company  or any of its
subsidiaries  to grant,  extend or enter into any such  option,  warrant,  call,
preemptive right, subscription or other right, convertible security,  agreement,
arrangement or commitment.

     (b) Except as set forth in Section 3.2(b) of the Company Disclosure Letter,
all of the outstanding shares of capital stock of each of the Company's material
subsidiaries are beneficially owned by the Company, directly or indirectly,  and
all such shares have been  validly  issued and are fully paid and  nonassessable
and are owned by either Company or one of its subsidiaries free and clear of all
Liens.

     (c) There are no voting  trusts or other  agreements or  understandings  to
which the Company or any of its material subsidiaries is a party with respect to
the  voting  of the  capital  stock  of  the  Company  or  any  of its  material
subsidiaries. None of the Company or its material subsidiaries is a party to any
agreement or  obligation,  contingent  or  otherwise,  to redeem,  repurchase or
otherwise acquire or retire shares of capital stock of the Company or any of its
material subsidiaries,  whether as a result of the transactions  contemplated by
this Agreement or otherwise.

     (d) Except as described in Section 3.2(d) of the Company  Disclosure Letter
or as  specifically  described in this Agreement or the Stock Option  Agreement,
since  September  30,  1998,  the Company has not (i) made or agreed to make any
stock split or stock dividend, or issued or permitted to be issued any shares of
capital  stock,  or securities  exercisable  for or  convertible  into shares of
capital  stock,  of the  Company  other than  pursuant to and as required by the
terms of any Company Option;  (ii) repurchased,  redeemed or otherwise  acquired
any shares of capital  stock of the  Company;  or (iii)  other than its  regular
quarterly cash dividend of $0.09 per share, declared, set aside, made or paid to
the  stockholders  of  the  Company  dividends  or  other  distributions  on the
outstanding shares of capital stock of the Company.

     Section 3.3 Corporate Authorization; Validity of Agreement; Company Action.
(a) The Company has full  corporate  power and  authority to execute and deliver
this  Agreement  and the Stock Option  Agreement  and,  subject to obtaining the
necessary  approval of its  stockholders  as contemplated by Section 5.2(b) with
respect to the Merger,  to consummate the transactions  contemplated  hereby and
thereby.  The  execution,  delivery  and  performance  by the  Company  of  this
Agreement  and the Stock Option  Agreement,  and the  consummation  by it of the
transactions  contemplated  hereby  and  thereby,  have  been  duly and  validly
authorized by its Board of Directors  and,  except for obtaining the approval of
its  stockholders  as contemplated by Section 5.2(b) with respect to the Merger,
no  other  corporate  action  or  proceedings  on the  part of the  Company  are
necessary  to  authorize  the  execution  and  delivery  by the  Company of this
Agreement,  and the consummation by it of the transactions  contemplated  hereby
and  thereby.  This  Agreement  and the Stock  Option  Agreement  have been duly
executed and delivered by the Company and, assuming this Agreement and the Stock
Option Agreement  constitute valid and binding obligations of Parent and Sub, as
applicable,  constitute valid and binding obligations of the Company enforceable
against the Company in accordance with their respective  terms,  except that (i)
such enforcement may be subject to applicable bankruptcy, insolvency, fraudulent
conveyance,  moratorium  or other  similar  laws,  now or  hereafter  in effect,
affecting  creditors'  rights  generally,   and  (ii)  the  remedy  of  specific
performance and injunctive and other forms of equitable relief may be subject to
equitable  defenses  and to  the  discretion  of  the  court  before  which  any
proceeding therefor may be brought.

     (b) The Board of Directors of the Company has duly and validly approved and
taken all  corporate  action  required to be taken by the Board of Directors (in
each case by a unanimous  vote of all the  directors in office at such time) for
the  consummation  of the  transactions  contemplated  by this Agreement and the
Stock Option  Agreement,  including,  but not limited to, (i) having  determined
that  this  Agreement,   the  Stock  Option   Agreement  and  the   transactions
contemplated hereby and thereby,  taken together,  are advisable and are fair to
and in the best  interests  of the  stockholders  of the  Company,  (ii)  having
resolved to  recommend  that the holders of the shares of Company  Common  Stock
adopt this  Agreement  and approve the Merger and (iii) having taken all actions
necessary to render the  provisions of Section 203 of the DGCL  inapplicable  to
this Agreement and the Stock Option Agreement.  The affirmative vote in favor of
the  adoption  of this  Agreement  by  stockholders  holding a  majority  of the
outstanding shares of Company Common Stock (the "Company Stockholder  Approval")
is the only vote of the holders of any class or series of Company  capital stock
necessary to approve this Agreement and the Merger.  No vote of the stockholders
of the Company is required to approve the Stock Option Agreement.

     Section 3.4 Consents and Approvals;  No Violations.  Except as set forth in
Section  3.4 of the  Company  Disclosure  Letter and for all  filings,  permits,
authorizations,  consents and approvals as may be required under, and compliance
with other applicable  requirements of, the Securities  Exchange Act of 1934, as
amended (the "Exchange Act"), the Hart-Scott-Rodino  Antitrust  Improvements Act
of 1976, as amended (the "HSR Act"),  state securities or "blue sky" laws, state
takeover laws,  state and foreign  insurance  regulatory  laws and  commissions,
including  Lloyd's  of  London  and the U.K.  Treasury  Department,  and for the
approval of this  Agreement  by the  Company's  stockholders  and the filing and
recordation  of this  Agreement or the  Certificate of Merger as required by the
DGCL,  neither the  execution,  delivery or performance of this Agreement or the
Stock Option  Agreement nor the  consummation by the Company of the transactions
contemplated  hereby or thereby nor  compliance  by the Company  with any of the
provisions  hereof or thereof  will (i) result in any breach or violation of any
provision  of  the   certificate   of   incorporation   or  by-laws  or  similar
organizational  documents  of the  Company or of any of its  subsidiaries,  (ii)
require any filing with, or permit,  authorization,  consent or approval of, any
United States or foreign  court,  arbitral  tribunal,  administrative  agency or
commission or other governmental or other regulatory authority, body, commission
or agency,  including  the  Corporation  of Lloyd's (a  "Governmental  Entity"),
except  where the failure to obtain such  permits,  authorizations,  consents or
approvals or to make such filings would not have a Material  Adverse Effect with
respect to the Company,  (iii) result in a violation or breach of, or constitute
(with or without due notice or lapse of time or both) a default (or give rise to
any right of termination,  amendment, cancellation,  acceleration or increase in
the rate of interest) under,  any of the terms,  conditions or provisions of any
note,  bond,  mortgage,  indenture,  guarantee,  other evidence of indebtedness,
lease, license,  contract,  agreement or other instrument or obligation to which
the Company or any of its subsidiaries is a party or by which any of them or any
of their properties or assets may be bound (a "Company  Agreement") or result in
the  creation of a Lien upon any of the  properties  or assets of the Company or
any of its subsidiaries or (iv) violate any order, writ,  injunction,  judgment,
decree,  statute, rule, regulation or law ("Law") applicable to the Company, any
of its subsidiaries or any of their properties or assets,  except in the case of
clauses  (iii)  and  (iv) for  violations,  breaches,  defaults,  or  rights  of
termination,  amendment, cancellation or acceleration or Liens, which would not,
individually  or in the  aggregate,  reasonably  be  expected to have a Material
Adverse Effect with respect to the Company.

     Section 3.5 SEC Filings;  Financial  Statements.  (a) The Company has filed
all forms, reports,  statements,  schedules,  registration  statements and other
documents  required to be filed with the SEC since January 1, 1996 (the "Company
SEC  Documents"),  each of which  complied  in all  material  respects  with the
applicable requirements of the Securities Act of 1933 (the "Securities Act") and
the rules and regulations  promulgated  thereunder,  or the Exchange Act and the
rules and regulations promulgated  thereunder,  each as in effect on the date so
filed.  No  subsidiary  of the  Company is  required  to file any form,  report,
statement,  schedule,  registration statement or other document with the SEC. No
Company SEC Document, when filed (or, if amended or superseded by a filing prior
to the  Closing  Date,  then on the date of such  filing)  contained  any untrue
statement of a material  fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading.

     (b) Each of the audited and unaudited  consolidated financial statements of
the Company  (including any related notes  thereto)  included in the Company SEC
Documents filed prior to the date hereof and the audited consolidated  financial
statements of the Company  (including  any related notes thereto) to be included
in the Company's  Annual Report on Form 10-K for the fiscal year ended  December
31, 1998, have been prepared in accordance with United States generally accepted
accounting  principles,  (except,  in  the  case  of  unaudited  statements,  as
permitted  by Form 10-Q of the SEC)  applied on a  consistent  basis  during the
relevant periods (except as may be disclosed in the notes thereto),  and present
fairly  the  consolidated   financial  position  and  consolidated   results  of
operations and changes in cash flows of the Company and its  subsidiaries  as of
the respective dates or for the respective periods reflected therein, except, in
the case of the unaudited interim financial statements, for normal and recurring
year-end adjustments that are not material.

     (c) Except to the extent set forth on the consolidated balance sheet of the
Company and its  subsidiaries  at September 30, 1998 included in the Company SEC
Documents (the "Latest  Balance  Sheet"),  or in the notes thereto,  neither the
Company  nor any of its  subsidiaries  has any  liabilities,  debts,  claims  or
obligations  of any  nature  (whether  accrued,  absolute,  direct or  indirect,
contingent or  otherwise,  whether due or to become due) which would be required
to be reflected on a balance sheet or in the notes  thereto in  accordance  with
United States generally accepted accounting principles, and there is no existing
condition  or  set  of   circumstances   which  would  reasonably  be  expected,
individually  or in the  aggregate,  to result in such a  liability,  except for

consistent with past practice since September 30, 1998, and liabilities incurred
pursuant to the terms of or as contemplated by this Agreement,  the Stock Option

reasonably  be expected to have a Material  Adverse  Effect with  respect to the
Company.

     (d) Each  Company  Insurance  Subsidiary  has filed  during the three years
ended December 31, 1998, all annual and quarterly statements,  together with all

and to any other jurisdiction where required on forms prescribed or permitted by
such authority.  Each Annual Statement filed by any Company Insurance Subsidiary

with SAP, the statutory financial condition of such Company Insurance Subsidiary

surplus and cash flow of such  subsidiary for each of the periods then ended. No
deficiencies  or violations  have been asserted by any insurance  regulator with
respect  to the  foregoing  Company  Annual  Statements  and  Company  Quarterly
Statements  which have not been cured or otherwise  resolved to the satisfaction
of such insurance regulator.

     Section 3.6 Absence of Certain Changes. Since September 30, 1998, there has
not occurred any event, change, circumstance, condition or effect (including the
incurrence of any liabilities of any nature, whether or not accrued,  contingent
or otherwise) having or reasonably likely to have, in the aggregate,  a Material
Adverse  Effect with  respect to the Company.  Since  September  30,  1998,  the

Statement/Prospectus") will, at the date the Proxy Statement/Prospectus is first
mailed to the Company's stockholders or at the time of the Stockholders Meeting,
contain any untrue  statement  of a material  fact or omit to state any material
fact required to be stated  therein or necessary in order to make the statements
therein,  in the light of the  circumstances  under  which  they are  made,  not
misleading or contain any  statements  which at the time and in the light of the
circumstances under which it is made, is false or misleading with respect to any
material  fact,  omit to state any material fact  necessary in order to make the
statements therein not false or misleading or necessary to correct any statement
in any earlier communication with respect to the solicitation of a proxy for the
Stockholders Meeting which has become false or misleading. The Form S-4 will, as
of its effective  date,  and the  prospectus  contained  therein will, as of its
date,  comply as to form in all material  respects with the  requirements of the
Securities Act and the rules and regulations promulgated  thereunder.  The Proxy

qualified,  to the  knowledge  of the  Company,  and has  received  a  favorable
determination letter as to its qualification,  and nothing has occurred, whether

Company Plan; (vi) no Company Plan provides retiree welfare benefits and neither
the Company nor its  subsidiaries  have any  obligations  to provide any retiree

pursuant  to  Section  601 et seq.  of ERISA);  and (vii) except as set forth in
Section 3.8(d) of the Company Disclosure  Letter, all awards,  grants or bonuses

the Company or its subsidiaries of any money or other property or accelerate the
time of payment or vesting,  or (iii) increase the amount payable or provide any

subsidiaries  have and are in compliance with all licenses,  permits,  and other
authorizations,  domestic  or foreign,  necessary  to conduct  their  respective
businesses,  except  where the  failure  to have or comply  with such  licenses,

     (c) Subject to obtaining the consents referred to in Section 3.4 and except
as set forth in Section  3.8(f) of the Company  Disclosure  Letter,  neither the
Company  nor any of its  subsidiaries  is a party to or  bound by any  contract,
agreement  or  arrangement  which would cause the rights or  obligations  of any
party thereto to change upon the consummation of the Merger, except for any such
contract,  agreement or  arrangement  which would not  reasonably be expected to
have,  individually or in the aggregate,  a Material Adverse Effect with respect
to the Company.

     Section  3.11  Absence  of  Litigation.  There is no claim,  suit,  action,
proceeding  or  investigation  pending  or,  to the  knowledge  of the  Company,
threatened  against the Company or any of its  subsidiaries,  or any property or
asset of the Company or any of its subsidiaries, before any court, arbitrator or
administrative,  governmental  or  regulatory  authority  or body,  domestic  or

(including  interest and penalties)  whether or not shown to be due and owing on

Section  3.12 of the Company  Disclosure  Letter:  (i) no claim for any material
amount of unpaid Taxes has been  proposed in writing  against the Company or any
of its subsidiaries or, to the best knowledge of the Company,  has become a Lien
of any kind  against  the  property  of the  Company or any of its  subsidiaries
(except for  statutory  Liens for current  Taxes not yet due and  payable) or is
being asserted in writing against the Company or any of its subsidiaries  (other
than in each case claims or  assertions  for which  adequate  reserves have been
established  in the Latest  Balance Sheet and which are being  contested in good
faith);  (ii) as of the date hereof no audit of any  material  Tax Return of the
Company or any of its  subsidiaries is being conducted by any Tax authority,  no
material audit or other  proceeding by any Tax authority has formally  commenced
and there is no material claim or assessment  pending,  and, to the knowledge of
the  Company,  no  written  notice  has  been  given  to  the  Company  and  its

under, any material Tax sharing  agreement or similar contract or arrangement or
any agreement that obligates it to make any payment computed by reference to the
Taxes, taxable income or taxable losses of any other person; and (v) none of the
Company nor any of its  subsidiaries  has been a member of an  affiliated  group
(other than the group to which it is currently a member)  filing a  consolidated
federal income Tax Return. As used herein,  the term "Tax" or "Taxes" shall mean
any taxes of any kind,  including  but not limited to those on or measured by or
referred  to as  income,  gross  receipts,  capital,  sales,  use,  ad  valorem,
franchise,   profits,  license,   withholding,   payroll,  employment,   excise,
severance, stamp, occupation, premium, value added, property or windfall profits
taxes,  customs,  duties or  similar  fees,  assessments  or charges of any kind

additional amounts imposed by any governmental  authority,  domestic or foreign.
As used herein, "Tax Return" shall mean any return, report or statement required
to be filed with any Governmental Entity with respect to Taxes.

     Section  3.13  Title  to  Properties;  Leases.  The  Company  has  good and
marketable  title  to,  and is the  lawful  owner  of,  or has the  right to use
pursuant to a license or otherwise,  all of the tangible and intangible  assets,
properties  and rights  reflected in the Latest  Balance Sheet or acquired since
the date of the Latest Balance  Sheet,  free and clear of all Liens and material
defects in title,  in each case except  where the failure to have title,  be the
owner or have the right to use would not  reasonably be expected to interfere in
any  material  respect  with the  conduct  of the  business  of the  Company  as
currently conducted.  The Company has provided Parent with a copy or an accurate
summary  of the  material  terms of all  material  real  property  and  personal
property  leases  of the  Company.  All  such  leases  are  valid,  binding  and
enforceable  against the Company  (and,  to the  knowledge of the Company,  each
other party thereto) in accordance with their  respective  terms, and there does
not exist under any lease of real  property or personal  property  any  material
defect in title or any event which,  with notice or lapse of time or both, would
constitute  a  material  default  by the  Company  or, to the  knowledge  of the
Company, by any other party thereto.

     Section 3.14 Intellectual Property.  The Company owns or possesses,  or has
all necessary rights to use, all patents,  patent rights,  licenses,  inventions
(whether  or  not  patentable  or  reduced  to  practice),  copyrights  (whether
registered  or  unregistered),  know-how  (including  trade  secrets  and  other
unpatented and/or unpatentable proprietary or confidential information,  systems
or procedures),  registered and unregistered trademarks, service marks and trade
names  and  other  intellectual  property  rights  (collectively,  "Intellectual
Property")  necessary to conduct its  business as  conducted  and proposed to be
conducted  except to the extent  that the  failure of the Company to own or have
such rights and licenses in such  Intellectual  Property would not reasonably be
expected to have a Material  Adverse  Effect with  respect to the  Company.  The
Company  has not  received  any  notice  of,  and is not  aware  of any  fact or
circumstance  that would give any person a right to assert,  any infringement or
misappropriation  of, or conflict with,  asserted rights of others or invalidity
or  unenforceability  of any  Intellectual  Property  owned by the Company  with
respect to any of the foregoing which,  individually or in the aggregate,  would
reasonably  be expected to have a Material  Adverse  Effect with  respect to the
Company.  To the best  knowledge  of the Company,  the use of such  Intellectual
Property to conduct the business and  operations  of the Company as conducted or
proposed to be  conducted  does not  infringe on the rights of any person in any
case where such  infringement  would  reasonably  be expected to have a Material
Adverse Effect with respect to the Company.  To the knowledge of the Company, no
person is  challenging,  infringing  on or otherwise  violating any right of the
Company with respect to any  Intellectual  Property owned by and/or  licensed to
the  Company.  Except as set forth in  Section  3.13 of the  Company  Disclosure
Letter,  neither the execution of this  Agreement or the Stock Option  Agreement
nor the  consummation of the  transactions  contemplated  hereby or thereby will
result in a loss of or  limitation  in the rights and licenses of the Company to
use or enjoy the benefit of any Intellectual Property employed by the Company in
connection with its business as conducted or proposed to be conducted where such
loss or  limitation,  individually  or in the  aggregate,  would  reasonably  be
expected to have a Material Adverse Effect with respect to the Company.

     Section  3.15  Insurance  Matters.  (a)  Except  as  otherwise  would  not,
individually  or in the  aggregate,  be  reasonably  expected to have a Material
Adverse  Effect with  respect to the  Company,  all  policies,  binders,  slips,
treaties, certificates, annuity contracts and participation agreements and other
agreements of insurance or reinsurance,  whether  individual or group, in effect
as of the date hereof  (including all applications,  supplements,  endorsements,
riders and ancillary agreements in connection therewith) (the "General Insurance
Contracts")  that are issued by the Company or its  subsidiaries and any and all
marketing  materials are, to the extent required under  applicable Law, on forms
approved by applicable insurance or reinsurance  regulatory authorities or which
have been  filed and not  objected  to by such  authorities  within  the  period
provided for objection,  and such forms comply in all material respects with the
insurance or reinsurance statutes, regulations and rules applicable thereto and,
as to premium  rates  established  by the  Company or any  subsidiary  which are
required to be filed with or approved by  insurance  or  reinsurance  regulatory
authorities,  the rates have been so filed or  approved,  the  premiums  charged
conform  thereto  in all  material  respects  and such  premiums  comply  in all
material  respects with the insurance or reinsurance  statutes,  regulations and
rules applicable thereto.

     (b)  Each  reinsurance  and  coinsurance  treaty  or  agreement,  including
retrocessional  agreements, to which the Company or any of its subsidiaries is a
party,  under  which the  Company or any of its  subsidiaries  has any  existing
rights,  duties,  obligations or liabilities or which is otherwise applicable to
the  Company  or  any of  its  subsidiaries,  assuming  its  due  authorization,
execution  and  delivery  by the other  party or parties  thereto,  is valid and
binding in all  material  respects in  accordance  with its terms and is in full
force and effect, except for such treaties or agreements the failure to be valid
and binding or in full force and effect of which would not,  individually  or in
the  aggregate,  reasonably be expected to have a Material  Adverse  Effect with
respect  to the  Company.  No party to any such  treaty or  agreement  has given
notice to the Company or any of its subsidiaries that it intends to terminate or
cancel  any  such  treaty  or  agreement  as a  result  of  the  Merger  or  the
contemplated  operations of the Company or its subsidiaries  after the Merger is
consummated,  which  termination or cancellation  would have a Material  Adverse
Effect with respect to the Company. Any subsidiary of the Company that has ceded
reinsurance  pursuant to any such treaty or  agreement  is entitled to take full
credit in its  financial  statements  for all  amounts  recoverable  (net of any
reserve  for  collectibility  under such treaty or  agreement)  with such credit
accounted  for (i)  pursuant  to SAP,  as a  reduction  of such  Company's  loss
reserves  and (ii)  pursuant  to United  States  generally  accepted  accounting
principles, as a reinsurance recoverable asset. The Company has no unrecoverable
reinsurance  balances,  other than as fully reserved on the Latest Balance Sheet
or specified in Section 3.15 of the Company Disclosure Letter.

     (c) The Company has not  received  any  written  notice that the  financial
condition of any other party to any  reinsurance,  coinsurance  or other similar
agreement  with it or any of its  subsidiaries  is so impaired as to result in a
default  thereunder,  except to the extent that adequate  reserves in respect of
any such default are reflected on the Latest Balance Sheet.

     (d) Prior to the date hereof,  the Company has delivered or made  available
to  Parent  a true  and  complete  copy of any  actuarial  reports  prepared  by
actuaries,  independent or otherwise, with respect to the Company or any Company
Insurance  Subsidiary  since  January 1,  1998,  and all  attachments,  addenda,
supplements and modifications  thereto (the "Company Actuarial  Analyses").  The
information  and  data  furnished  by  the  Company  or  any  Company  Insurance
Subsidiary to its  independent  actuaries in connection  with the preparation of
the Company Actuarial Analyses were accurate in all material respects.

     (e) As of the date  hereof,  the Company has no reason to believe  that any
rating  presently held by the Company or any of its subsidiaries is likely to be
modified,  qualified,  lowered  or  placed  under  surveillance  for a  possible
downgrade for any reason other than as a result of the transactions contemplated
hereby.

     Section 3.16  Liabilities and Reserves.  (a) Except for instances where the
failure of any of the following  statements  to be true would not  reasonably be
expected, individually or in the aggregate, to have a Material Adverse Effect on
the Company,  (i) the reserves carried on the statutory financial  statements of
each Company Insurance Subsidiary for future insurance policy benefits,  losses,
claims and similar  purposes were, as of the respective  dates of such financial
statements,  in compliance with the requirements for reserves established by the
insurance  departments of the jurisdiction of domicile of such Company Insurance
Subsidiary and each other jurisdiction where it is regulated or (as the case may
be) by the  Corporation of Lloyd's,  were  determined in accordance with SAP and
with  generally  accepted  actuarial   standards,   assumptions  and  principles
consistently  applied, and were fairly stated in accordance with sound actuarial
and statutory accounting principles;  (ii) such reserves were, in the reasonable
judgment of the Company,  adequate in the aggregate to cover the total amount of
all reasonably anticipated liabilities of the Company and each Company Insurance
Subsidiary  under all outstanding  insurance,  reinsurance and other  applicable
agreements as of the respective  dates of such financial  statements;  and (iii)
the statutory surplus of each Company  Insurance  Subsidiary as determined under
applicable laws or under the Lloyd's regulations are in an amount at least equal
to the minimum amounts required by applicable laws or regulations.

     (b) Except for  regular  periodic  assessments  in the  ordinary  course of
business or assessments  based on  developments  which are publicly known within
the insurance and reinsurance industry, to the best knowledge of the Company and
its  subsidiaries,  no claim or assessment is pending or threatened  against any
subsidiary which is peculiar or unique to such subsidiary by any state insurance
guaranty  associations  in connection with such  association's  fund relating to
insolvent insurers which if determined adversely,  would, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect with respect
to the Company.

     Section 3.17  Environmental Laws . Except to the extent that any inaccuracy
in any of the following  representations,  individually or in the aggregate with
any other inaccuracy under the respective following  representations,  would not
reasonably  be expected to have a Material  Adverse  Effect with  respect to the
Company,  (a) each of the Company and each of its  subsidiaries is in compliance
with all Environmental  Laws applicable to the properties,  assets or businesses
of the Company and its  subsidiaries,  and  possesses  and complies with and has
possessed and complied with all Environmental  Permits required under such laws;
(b) none of the Company and its  subsidiaries  has  received  any  Environmental
Claim,  and none of the Company and its  subsidiaries is aware after  reasonable
inquiry of any  threatened  Environmental  Claim or of any  Environmental  Claim
pending or  threatened  against  any entity for which the  Company or any of its
subsidiaries  may be responsible;  (c) none of the Company and its  subsidiaries
has  assumed,   contractually  or  by  operation  of  law,  any  liabilities  or
obligations  under any  Environmental  Laws; (d) there are no present or, to the
best  knowledge  of  the  Company,  past  events,   conditions,   circumstances,
practices,  plans or legal  requirements  that would  reasonably  be expected to
result  in  liability  to  the  Company  or  any  of  its   subsidiaries   under
Environmental Laws, prevent, or reasonably be expected to increase the burden on
the Company or any of its subsidiaries of, complying with  Environmental Laws or
of obtaining,  renewing,  or complying with all  Environmental  Permits required
under such laws; (e) there are and, to the best knowledge of the Company,  there
have been no  Hazardous  Materials or other  conditions  at or from any property
owned,  operated or otherwise used by the Company or any of its subsidiaries now
or, to the best knowledge of the Company,  in the past that would  reasonably be
expected to give rise to  liability  of the  Company or any of its  subsidiaries
under any  Environmental  Law;  and (f) the Company  has  provided to Parent all
Environmental  Reports in the possession or control of the Company or any of its
subsidiaries. For purposes of this Agreement, the following terms shall have the
following meanings:

                                   ARTICLE IV

                REPRESENTATIONS AND WARRANTIES OF PARENT AND SUB

     Parent and Sub represent and warrant to the Company as follows:

     Section 4.1  Organization.  (a) Each of Parent and Sub is a corporation  or
other  business  organization  duly  organized,  validly  existing  and in  good
standing  under  the  laws  of  the   jurisdiction  of  its   incorporation   or
organization.  Each of Parent and its subsidiaries (i) is qualified, licensed or

and (iii) has full power and authority  (corporate  and other) to own, lease and
operate its  respective  properties  and assets and to carry on its  business as
presently conducted and as proposed to be conducted, except where the failure to
be so qualified, licensed or domesticated,  or to hold such franchises,  grants,
licenses,  certificates,  permits, consents and orders or to have such power and
authority  would  not,  when  taken  together  with  all  other  such  failures,
reasonably be expected to have a Material Adverse Effect with respect to Parent.
Parent  has  furnished  to  the  Company  complete  and  correct  copies  of its
memorandum and articles of association  and Sub's  certificate of  incorporation
and by-laws as in effect on the date hereof.  Such  documents  are in full force
and effect and no other  organizational  documents are  applicable to or binding
upon Parent or Sub.

     (b) Each  material  subsidiary  of Parent that is an  insurance  company (a
"Parent  Insurance  Subsidiary") has filed during the three years ended December
31, 1998,  all  financial  statements,  together with all exhibits and schedules
thereto,  required to be filed with or submitted to the  appropriate  regulatory
authorities  of the  jurisdiction  in which  it is  domiciled  and to any  other
jurisdiction  where required on forms prescribed or permitted by such authority.
Each  annual  statement  filed  by any  Parent  Insurance  Subsidiary  with  the
insurance  regulator in its  jurisdiction  of domicile for the three years ended
November 30, 1997 (each a "Parent Annual Statement"), together with all exhibits
and schedules thereto,  financial  statements relating thereto and any actuarial
opinion,  affirmation  or  certification  filed in connection  therewith and any

the extent  required by and in  conformity  with SAP,  the  statutory  financial
condition of such Parent Insurance  Subsidiary at their respective dates and the
results of  operations,  changes in capital  and  surplus  and cash flow of such
subsidiary  for each of the periods then ended.  No  deficiencies  or violations
have been  asserted by any  insurance  regulator  with respect to the  foregoing
Parent Annual  Statements and Parent  Quarterly  Statements  which have not been
cured or otherwise resolved to the satisfaction of such insurance regulator.

     Section 4.2 Capital  Structure.  (a) As of the date hereof,  the authorized
share capital of Parent is $9,999,900  comprised of 999,990,000  ordinary shares
with a par value of $0.01 per share.  As of  February 1, 1999,  (i)  109,013,614
Parent  Ordinary Shares were issued and  outstanding  (excluding  509,700 Parent
Ordinary  Shares held in treasury,  which for purposes of Cayman Islands law are
deemed to be cancelled),  (ii)  3,115,873  Non-Voting  Common Shares,  par value

distributed  to the  holders of Parent  Ordinary  Shares  pursuant to the Rights
Agreement dated as of December 1, 1996 (the "Parent Rights Agreement"),  between
Parent  and Mellon  Securities  Trust  Company.  All the  outstanding  shares of
Parent's  share  capital are duly  authorized,  validly  issued,  fully paid and
non-assessable.  The Parent  Ordinary  Shares to be issued in the  Merger,  when
issued in accordance  with the terms hereof,  will be duly  authorized,  validly

Action.  (a) Each of Parent and Sub has full  corporate  power and  authority to

of this  Agreement and the  consummation  by Parent and Sub of the  transactions
contemplated  hereby have been duly and validly  authorized by their  respective
boards of directors, and no other corporate action or proceedings on the part of
Parent or Sub are necessary to authorize the execution and delivery by Parent or
Sub of this Agreement and the consummation by Parent and Sub of the transactions
contemplated  hereby.  This  Agreement  has been duly  executed and delivered by
Parent and Sub,  and,  assuming this  Agreement  constitutes a valid and binding
obligation of the Company, constitutes a valid and binding obligation of each of
Parent and Sub,  enforceable  against each of them in accordance with its terms,

insolvency,  fraudulent  conveyance,  moratorium or other  similar laws,  now or
hereafter in effect,  affecting creditors' rights generally, and (ii) the remedy
of specific  performance and injunctive and other forms of equitable  relief may

Stock Option  Agreement and the  transactions  contemplated  hereby and thereby,
taken together,  are fair to and in the best interests of Parent. No vote of the

memorandum or articles of  association  or similar  organizational  documents of
Parent or any of its  subsidiaries,  (ii)  require any filing  with,  or permit,
authorization, consent or approval of, any Governmental Entity, except where the
failure to obtain such permits, authorizations, consents or approvals or to make

notice  or lapse  of time or  both) a  default  (or  give  rise to any  right of
termination,  amendment, cancellation or acceleration or increase in the rate of
interest) under,  any of the terms,  conditions or provisions of any note, bond,
mortgage, indenture, guarantee, other evidence of indebtedness,  lease, license,
contract,  agreement or other instrument or obligation to which Parent or any of
its subsidiaries is a party or by which or any of their properties or assets may

the properties or assets of Parent or (iv) violate any Law applicable to Parent,
any of its subsidiaries or any of their properties or assets, except in the case
of  clauses  (iii) and (iv) for  violations,  breaches,  defaults,  or rights of

promulgated thereunder, each as in effect on the date so filed. No subsidiary of
Parent is required to file any form, report, statement,  schedule,  registration

date of such  filing)  contained  any untrue  statement  of a  material  fact or
omitted to state a material fact  required to be stated  therein or necessary in
order to make the statements  therein, in light of the circumstances under which
they were made, not misleading.

     (b) Each of the audited and unaudited  consolidated financial statements of
Parent  (including  any  related  notes  thereto)  included  in the  Parent  SEC

to be reflected on a balance sheet or in the notes  thereto in  accordance  with
United States generally accepted accounting principles, and there is no existing
condition  or  set  of   circumstances   which  would  reasonably  be  expected,
individually  or in the  aggregate,  to result in such a  liability,  except for

consistent  with past practice since August 31, 1998, and  liabilities  incurred
pursuant to the terms of or as contemplated by this Agreement,  the Stock Option

document,  (ii) any Law  applicable to Parent or any of its  subsidiaries  or by
which any of their  respective  properties  or assets is bound or  affected,  or

reasonably be expected to have a Material Adverse Effect with respect to Parent.
Parent  and its  subsidiaries  have and are in  compliance  with  all  licenses,
permits,  and other  authorizations,  domestic or foreign,  necessary to conduct
their  respective  businesses,  except  where the failure to have or comply with

aggregate, reasonably be expected to have a Material Adverse Effect with respect
to Parent.

     Section  4.10  Absence  of  Litigation.  There is no claim,  suit,  action,
proceeding or investigation  pending or, to the knowledge of Parent,  threatened
against  Parent  or any of its  subsidiaries,  or any  property  or asset of the

reinsurance statutes, regulations and rules applicable thereto.

     (b)  Each  reinsurance  and  coinsurance  treaty  or  agreement,  including
retrocessional  agreements,  to which  Parent  or any of its  subsidiaries  is a
party,  under which Parent or any of its  subsidiaries  has any existing rights,
duties, obligations or liabilities or which is otherwise applicable to Parent or
any of its subsidiaries, assuming its due authorization,  execution and delivery
by the other  party or parties  thereto,  is valid and  binding in all  material
respects in  accordance  with its terms and is in full force and effect,  except
for such treaties or  agreements  the failure to be valid and binding or in full
force  and  effect  of  which  would  not,  individually  or in  the  aggregate,
reasonably be expected to have a Material Adverse Effect with respect to Parent.
No party to any such treaty or  agreement  has given  notice to Parent or any of
its  subsidiaries  that it intends  to  terminate  or cancel any such  treaty or
agreement as a result of the Merger or the contemplated  operations of Parent or
its  subsidiaries  after  the  Merger  is  consummated,   which  termination  or
cancellation  would have a Material  Adverse Effect with respect to Parent.  Any
subsidiary of Parent that has ceded  reinsurance  pursuant to any such treaty or
agreement is entitled to take full credit in its  financial  statements  for all
amounts recoverable (net of any reserve for collectibility  under such treaty or
agreement) with such credit accounted for (i) pursuant to SAP, as a reduction of
Parent's loss reserves and (ii)  pursuant to United  States  generally  accepted
accounting  principles,  as a  reinsurance  recoverable  asset.  Parent  has  no
unrecoverable   reinsurance  balances  which  would,   individually  or  in  the
aggregate, reasonably be expected to have a Material Adverse Effect with respect
to Parent, other than as fully reserved on the Latest Parent Balance Sheet.

     (c) Parent has not received any written notice that the financial condition
of any other party to any  reinsurance,  coinsurance or other similar  agreement
with it or any of its  subsidiaries  is so  impaired  as to  result in a default
thereunder,  except to the extent that adequate  reserves in respect of any such
default are reflected on the Latest Parent Balance Sheet.

     (d) Prior to the date hereof, Parent has delivered or made available to the
Company a true and complete copy of any actuarial reports prepared by actuaries,
independent  or  otherwise,  with respect to the Parent or any Parent  Insurance
Subsidiary since January 1, 1998, and all attachments,  addenda, supplements and
modifications  thereto (the "Parent  Actuarial  Analyses").  The information and
data furnished by Parent or any Parent  Insurance  Subsidiary to its independent
actuaries in connection  with the preparation of the Parent  Actuarial  Analyses
were accurate in all material respects.

     (e) As of the date hereof,  Parent has no reason to believe that any rating
presently  held by Parent or any of its  subsidiaries  is likely to be modified,
qualified, lowered or placed under surveillance for a possible downgrade for any
reason other than as a result of the transactions contemplated hereby.

     Section 4.16  Employee  Benefit  Plans.  (a) Section  4.16(a) of the Parent
Disclosure  Letter  contains a true and complete list of each "employee  benefit
plan"  (within the  meaning of Section  3(3) of ERISA) that is subject to ERISA.
All  such  plans,  agreements,  programs,  policies  and  arrangements  shall be
collectively referred to as the "Parent Plans".

     (b) (i) Each  Parent  Plan has been  established  and  administered  in all
material  respects  in  accordance  with its  terms,  and in  compliance  in all
material  respects  with  applicable  Law and (ii) no event has  occurred and no
condition exists that would subject Parent or its subsidiaries,  either directly
or by reason of their  affiliation with any member of their  "Controlled  Group"
(defined  as any  organization  which  is a  member  of a  controlled  group  of
organizations  within the meaning of  Sections  414(b),  (c),  (m) or (o) of the
Code), to any material tax, fine,  lien,  penalty or other liability  imposed by
applicable Law.

     Section 4.17  NYSE  Listing.  Parent  does not know of any  reason  why the
Parent  Ordinary  Shares to be issued in the  Merger  and upon the  exercise  of
Converted Stock Options would not be approved for listing on the NYSE.

     Section 4.18 Year 2000.  Parent is in the process of reviewing  its and its
subsidiaries'  software and hardware  systems that perform critical or important
accounting,  data processing, data storage, data transmission and report writing
functions for the purposes of evaluating its Y2K Readiness.  In connection  with
this  process,  Parent has  undertaken to obtain  assurances  from its principal
software suppliers and service firms as to the Y2K Readiness of certain critical
or important  systems obtained from these outside sources or utilized by them in
providing  critical  services to Parent.  Parent  reasonably  believes  that all
software,  hardware and equipment (including  microprocessors) that is owned by,
or  leased  or  licensed  by or to,  Parent  or any of its  subsidiaries  in the
operations of its or their respective  business will be capable, by December 31,
1999,  of accounting  for all  calculations  using a century and date  sensitive
algorithm  for the year  2000 and the fact that the year 2000 is a leap year and
to otherwise  continue to function without any material  interruption  caused by
the occurrence of the year 2000. In the event of a Y2K related  failure,  Parent
will have in place a business  contingency plan that will address the continuity
of critical business processes into the Year 2000.

Statement/Prospectus,  and Parent  shall  prepare and file with the SEC the Form
S-4, in which the Proxy  Statement/Prospectus  will be included.  Each of Parent
and the  Company  shall use its  reasonable  best  efforts  to have the Form S-4
declared  effective  under the Securities  Act as promptly as practicable  after
such  filing  and to keep the  Form S-4  effective  as long as is  necessary  to
consummate the Merger.  Parent shall also take any action (other than qualifying
to do business in any jurisdiction in which it is not now so qualified or filing
a  general  consent  to  service  of  process)  required  to be taken  under any
applicable  state  securities laws in connection with the issuance of the Parent
Ordinary  Shares in the Merger and the Company  shall  furnish  all  information
concerning  the  Company  and the  holders  of  Company  Common  Stock as may be
reasonably  requested  in  connection  with any such action.  The parties  shall
promptly provide copies,  consult with each other and prepare written  responses

Proxy  Statement/Prospectus  and the Form S-4 and advise one another of any oral
comments  with  respect  to the  Proxy  Statement/Prospectus  and the  Form  S-4
received  from the SEC. The parties will  cooperate in preparing and filing with
the SEC any necessary amendment or supplement to the Proxy  Statement/Prospectus
or the Form S-4. No amendment or  supplement  to the Proxy  Statement/Prospectus
shall be filed without the approval of both parties,  which  approvals shall not
be  unreasonably  withheld or delayed.  The Company will use its best efforts to
cause the Proxy  Statement/Prospectus to be mailed to the Company's stockholders
as promptly as practicable  after the Form S-4 is declared  effective  under the
Securities Act.

     (b) Whether or not the Board of  Directors  of the  Company  shall take any
action permitted by the third sentence of this 5.2(b), the Company shall cause a
meeting of its stockholders (the  "Stockholders  Meeting") to be duly called and
held as soon as practicable  after the date of this Agreement for the purpose of
voting on the adoption of this Agreement.  The Board of Directors of the Company
shall (i) include in the Proxy Statement/Prospectus the recommendation described
in Section  3.3(b)(ii)  (the  "Company  Board  Recommendation")  and the written
opinion of Morgan Stanley, dated the date of this Agreement, to the effect that,
as of the date hereof,  the Exchange  Ratio is fair,  from a financial  point of
view, to the holders of Company  Common Stock and (ii) use its  reasonable  best
efforts to obtain the necessary  vote in favor of the adoption of this Agreement
by its  stockholders.  The Board of Directors of the Company shall not withdraw,
amend,  modify or  qualify  in a manner  adverse  to Parent  the  Company  Board
Recommendation  (or announce publicly its intention to do so), except that prior
to the receipt of the Company  Stockholder  Approval,  the Board of Directors of
the Company shall be permitted to withdraw,  amend, modify or materially qualify
in a manner  adverse to Parent the Company  Board  Recommendation  (or  publicly
announce its  intention  to do so),  upon three  business  days' prior notice to
Parent,  but only if (i) the Company has  complied  with  Section  5.8,  (ii) an
unsolicited bona fide written  Transaction  Proposal with respect to the Company
shall have been made after the date of this  Agreement  by any person other than
Parent  or its  affiliates  and such  proposal  is  pending  at the time of such
action,  and (iii) the Board of Directors of the Company shall have concluded in
good  faith,  on the  basis of the  advice  of its  outside  financial  advisors
(confirmed in writing to the Board of Directors), that such Transaction Proposal
is a Superior  Proposal (as defined in Section 5.8), and, on the basis of advice
of its  outside  U.S.  legal  counsel  (confirmed  in  writing  to the  Board of
Directors), that the Board of Directors is required to withdraw, amend or modify
the  Company  Board  Recommendation  in order to prevent it from  breaching  its
fiduciary duties to the stockholders of the Company under the DGCL.

     Section 5.3 Access to  Information.  (a) The Company shall (and shall cause
each of its  subsidiaries  to) afford to the officers,  employees,  accountants,

Effective Time, to all of its and its subsidiaries' personnel, offices and other
facilities, books, contracts, commitments and records (including any Tax Returns

may  reasonably  request  (including  any  Tax  Returns  or  other  Tax  related
information  pertaining to the Company and its  subsidiaries).  Parent will hold
any such  information  which is nonpublic in confidence  in accordance  with the
provisions  of the existing  confidentiality  agreement  between the Company and
Parent, dated December 1, 1998 (the "Confidentiality Agreement").

     (b) Parent  shall (and shall cause each of its  subsidiaries  to) afford to
the officers, employees, accountants, counsel, actuaries, financial advisors and

subsidiaries' personnel,  offices and other facilities, and, during such period,
Parent shall (and shall cause each of its  subsidiaries  to) furnish promptly to

nonpublic in confidence in accordance with the provisions of the Confidentiality
Agreement.

     Section 5.4 Consents and Approvals. (a) Each of the Company, Parent and Sub
will  use its  reasonable  best  efforts  to  comply  promptly  with  all  legal

subsidiaries  to, take all reasonable  actions  necessary to obtain any consent,
authorization,  order or  approval  of, or any  exemption  by, any  Governmental
Entity or other public or private third party required to be obtained or made by
Parent,  Sub,  the  Company or any of their  subsidiaries  or  necessary  in the
reasonable  opinion of Parent,  Sub or the Company in connection with the Merger
or the taking of any action contemplated thereby or by this Agreement.

     (b) The Company and Parent will (i) take all actions  necessary to make the
filings  required of it or its affiliates  under the HSR Act with respect to the
transactions contemplated by this Agreement as promptly as practicable following
the  date of this  Agreement,  (ii)  comply  with  any  request  for  additional

parties hereto agrees to use its reasonable best efforts to take, or cause to be
taken, all actions and to do, or cause to be done, all things necessary,  proper
or advisable,  whether under applicable laws and regulations or otherwise, or to
remove any injunctions or other impediments or delays,  legal or otherwise,  (i)
to cause the  conditions  to closing  set forth in  Article VI to be  satisfied,
including  using its best efforts to satisfy the  condition set forth in Section
6.1(g),  and (ii)  otherwise to consummate and make effective the Merger and the
other transactions contemplated by this Agreement. In case at any time after the
Effective  Time any further  action is  necessary  or desirable to carry out the
purposes of this Agreement,  the proper officers and directors of Parent and the
Surviving  Corporation shall use all reasonable  efforts to take, or cause to be
taken, all such necessary actions.

     Section 5.5 Supplemental Information. Except where prohibited by applicable
statutes and  regulations,  each party shall promptly  provide the other (or its
counsel) with copies of all filings, material notices or material communications
made by such party with any Governmental  Entity  (including the SEC or NYSE) in
connection with this Agreement or the transactions contemplated hereby.

     Section 5.6 Employee Matters. (a) For a period of three years following the
Effective Time, Parent shall either continue the existing Company Plans or shall
provide, or cause the Surviving Corporation to provide, benefits to employees of
the Company and its subsidiaries under substitute plans or arrangements ("Parent
Benefit  Plans") that are no less  favorable in the aggregate to such  employees
than those provided under such existing Company Plans.

     (b) For purposes of determining  eligibility for  participation and vesting
under  any  Parent  Benefit  Plans  (but not to the  extent  it  results  in any
duplication of benefits),  employees of the Company and its  subsidiaries  shall
receive service credit for service with the Company and any of its  subsidiaries
to the same extent such service was granted under the Company Plans.

     (c) Parent shall cause the Surviving  Corporation to assume,  recognize and

reasonable  best  efforts to cause to be delivered to Parent a letter of Ernst &
Young LLP, the Company's independent public accountants, dated a date within two
business  days before the date on which the Form S-4 shall become  effective and
addressed to Parent, in form and substance reasonably satisfactory to Parent and
customary in scope and substance  for letters  delivered by  independent  public
accountants in connection with registration  statements similar to the Form S-4.
In connection with the Company's  efforts to obtain such letter, if requested by
Ernst & Young LLP, Parent shall provide a representation letter to Ernst & Young
LLP complying with SAS 72, if then required.

     (b) Parent shall use its  reasonable  best efforts to cause to be delivered

and substance reasonably  satisfactory to the Company and customary in scope and
substance for letters delivered by independent  public accountants in connection
with  registration  statements  similar  to the Form  S-4.  In  connection  with
Parent's efforts to obtain such letter,  if requested by  PricewaterhouseCoopers
LLP, the Company shall provide a representation letter to PricewaterhouseCoopers
LLP complying with SAS 72, if then required.

     Section 5.8 No  Solicitation.  From and after the date hereof,  neither the
Company  nor any of its  subsidiaries  shall  (whether  directly  or  indirectly
through its or their officers, directors, agents,  representatives,  advisors or
other intermediaries (collectively,  "Representatives")),  nor shall the Company
or  any  of  its   subsidiaries   authorize  or  permit  any  of  its  or  their
Representatives  to,  (a)  solicit,  initiate,  encourage  (including  by way of
furnishing   information)  or  take  any  action  knowingly  to  facilitate  the
submission  of any  inquiries,  proposals or offers  (whether or not in writing)
from any person  relating to, other than the  transactions  contemplated by this
Agreement and the Stock Option Agreement, (i) any acquisition or purchase of 15%

or  more  of  any  class  of  equity  securities  of the  Company  or any of its
subsidiaries,  (ii) any tender offer (including a self tender offer) or exchange

subsidiaries  (including  through the  ownership of  securities  convertible  or
exercisable  into or exchangeable for equity  securities of the Company),  (iii)
any merger,  consolidation,  business combination, sale of substantially all the
assets,  recapitalization,   liquidation,  dissolution  or  similar  transaction
involving the Company or any of its subsidiaries  whose assets,  individually or
in the  aggregate,  constitute  15% or more of the  consolidated  assets  of the
Company,  or (iv) any other transaction the consummation of which would or would
reasonably be expected to impede,  interfere with,  prevent or materially  delay
the Merger (any of the  foregoing,  a  "Transaction  Proposal"),  or agree to or
endorse  any  Transaction  Proposal,  or (b) enter  into or  participate  in any
discussions or  negotiations  regarding any of the foregoing,  or furnish to any
other person any information with respect to its business,  properties or assets
in connection with any of the foregoing, or otherwise cooperate in any way with,
or knowingly  assist or participate in,  facilitate or encourage,  any effort or
attempt  by any  other  person  to do or seek  any of the  foregoing;  provided,
however, that the foregoing shall not prohibit the Company, prior to the receipt
of the Company Stockholder Approval, (A) from complying with Rule 14e-2 and Rule
14d-9 under the Exchange Act with regard to a bona fide tender offer or exchange
offer  or  (B)  from  participating  in  negotiations  or  discussions  with  or
furnishing information to any person in connection with an unsolicited bona fide
Transaction  Proposal  which is submitted in writing by such person to the Board
of Directors of the Company  after the date of this  Agreement  and prior to the
Company  Stockholder  Approval;   provided  further,   however,  that  prior  to
participating  in  any  such  discussions  or  negotiations  or  furnishing  any
information,   (i)  the   Company   receives   from  such   person  an  executed
confidentiality  agreement  on terms not less  favorable to the Company than the
Confidentiality  Agreement,  a copy of which shall be provided for informational
purposes  only to Parent,  and (ii) the Board of Directors of the Company  shall
have  concluded  in good  faith,  based on the advice of its  outside  financial
advisors, that such Transaction Proposal is reasonably likely to be or to result
in a Superior  Proposal,  and based on the written  advice of its  outside  U.S.
legal  counsel,  that  participating  in such  negotiations  or  discussions  or
furnishing  such  information  is  required  in order to  prevent  the  Board of
Directors of the Company from breaching its fiduciary duties to its stockholders
under the DGCL;  and  provided,  further,  that the  Board of  Directors  of the
Company shall not take any of the foregoing  actions  unless it provides  Parent
with  contemporaneous  notice thereof.  If the Board of Directors of the Company
receives a Transaction  Proposal,  then the Company shall promptly inform Parent
in writing of the terms and  conditions of such proposal and the identity of the
person  making it. The Company  agrees that it will keep Parent  informed,  on a
current  basis,  of the terms of any such proposals or offers and, to the extent
disclosure is not prohibited by the terms of any confidentiality  agreement with
the party  making such  Transaction  Proposal,  the status of any such  material
discussions or negotiations.  The Company agrees to immediately  cease and cause
its  Representatives  to cease any and all existing  activities,  discussions or
negotiations  with any parties  conducted  heretofore with respect to any of the
foregoing,  and shall use its reasonable  best efforts to cause any such parties
in possession of confidential  information  about the Company that was furnished
by or on behalf of the Company to return or destroy all such  information in the
possession of any such party or in the possession of any agent or advisor of any
such party. The Company agrees not to release any third party from, or waive any
provisions of, any  confidentiality or standstill  agreement to which such party
or its  subsidiaries  is a party.  The Company  shall ensure that its  officers,
directors  and  employees  and any  investment  banker  or other  Representative
retained by it are aware of the  restrictions  described  in this  Section  5.8.
"Superior Proposal" means any of the transactions  described in clause (i), (ii)
or (iii) of the definition of Transaction  Proposal (with all of the percentages
included  in the  definition  of such term  raised to 51% for  purposes  of this
definition) with respect to which any required financing is committed or, in the
good faith  judgment  of the Board of  Directors  of the  Company,  based on the
written advice of its outside financial advisors, is reasonably capable of being
financed by the person making the proposal,  and with respect to which the Board
of Directors  of the Company  shall have  concluded in good faith,  based on the
written  advice  of  its  outside  legal  counsel  and  financial  advisors,  is
reasonably capable of being completed, taking into account all legal, financial,
regulatory and other aspects of the  Transaction  Proposal and the person making
the proposal, and would, if consummated,  result in a transaction more favorable
to the Company's  stockholders from a strategic and financial point of view than
the transactions contemplated by this Agreement.

     Section 5.9 Publicity.  So long as this Agreement is in effect, neither the
Company nor Parent nor their  affiliates shall issue or cause the publication of
any press release or other public statement or announcement with respect to this
Agreement or the transactions  contemplated hereby without prior approval of the
other party, except as may be required by law or by obligations  pursuant to any
listing agreement with a national  securities  exchange,  and in such case shall
use all reasonable efforts to consult with the other party prior to such release
or announcement being issued.

     Section 5.10 Notification of Certain Matters. The Company shall give prompt
notice to Parent, and Parent shall give prompt notice to the Company, of (a) the
occurrence or  non-occurrence  of any event the occurrence or  non-occurrence of
which  would cause any  representation  or warranty of the Company or Parent and
Sub, as the case may be,  contained in this Agreement to be untrue or inaccurate
in any material  respect at or prior to the Effective  Time and (b) any material
failure of the Company or Parent,  as the case may be, to comply with or satisfy
any  covenant,  condition or  agreement  to be complied  with or satisfied by it
hereunder;  provided,  however, that the delivery of any notice pursuant to this
Section  5.10  shall  not  limit or  otherwise  affect  the  remedies  available
hereunder to the party receiving such notice.

     Section 5.11 Directors' and Officers'  Insurance and  Indemnification.  (a)
The  Surviving   Corporation   shall,  and  Parent  shall  cause  the  Surviving
Corporation  to, (i) indemnify and hold  harmless,  and provide  advancement  of
expenses to, all past and present  directors and officers of the Company and its
subsidiaries  to the same extent such persons are  indemnified or have the right
to  advancement  of  expenses  as of the date of this  Agreement  by the Company
pursuant  to the  Company's  certificate  of  incorporation  and  by-laws  as in
existence on the date hereof for acts or omissions  occurring at or prior to the
Effective Time (including for acts or omissions occurring in connection with the
approval of this Agreement and the Stock Option  Agreement and the  consummation
of the  transactions  contemplated  hereby and thereby) and (ii) ensure that the
certificate of incorporation and by-laws of the Surviving  Corporation following
the Merger shall contain  provisions  identical  with respect to  elimination of
personal liability and  indemnification to those set forth in the certificate of
incorporation  and by-laws of the Company,  which  provisions  shall continue in
full force and effect and shall not (except as otherwise  required by applicable
law) be amended,  repealed or otherwise  modified for a period of six years from
the  Effective  Time in any  manner  that  would  adversely  affect  the  rights
thereunder of individuals who at or immediately prior to the Effective Time were
directors, officers, agents or employees of the Company.

     (b) Parent shall cause the Surviving  Corporation to maintain in effect for
four  years  from the  Effective  Time  policies  of  directors'  and  officers'
liability  insurance   containing  terms  and  conditions  which  are  not  less
advantageous in any material  respect  (including with respect to the payment of
reasonable  attorneys'  fees,  to the extent so  provided)  than those  policies
maintained by the Company at the date hereof,  with respect to matters occurring
prior to the  Effective  Time, to the extent  available,  and having the maximum
available  coverage  under the current  policies  of  directors'  and  officers'
liability insurance; provided that (i) Parent following the Effective Time shall
not be  required  to spend an amount in any year in excess of 150% of the annual
aggregate  premiums  currently  paid by the  Company  for  such  insurance;  and
provided, further, that if the annual premiums of such insurance coverage exceed
such amount,  Parent shall be obligated to cause the  Surviving  Corporation  to
obtain a policy with the best coverage available,  in the reasonable judgment of
the Board of Directors of Parent following the Merger,  for a cost not exceeding
such amount,  and (ii) in the sole discretion of Parent (x) such policies may be
one or more "tail" policies for all or any portion of the full four-year  period
or (y) Parent may cause  comparable  coverage in  accordance  with the foregoing
clauses  to be  provided  under any  policy  maintained  for the  benefit of the
directors and officers of Parent or any of its subsidiaries.

     (c) In the  event  that  any  action,  suit,  proceeding  or  investigation
relating  hereto  or to the  transactions  contemplated  by  this  Agreement  is
commenced,  whether before or after the Effective Time, the parties hereto agree
to cooperate  and use their  respective  reasonable  best efforts to  vigorously
defend against it and respond thereto.

     Section 5.12 Listing of Parent Ordinary  Shares.  Parent shall use its best
efforts to cause the Parent  Ordinary  Shares to be issued in the Merger and the
Parent  Ordinary  Shares  to be  reserved  for  issuance  upon  exercise  of the
Converted  Options to be approved  for listing on the NYSE,  subject to official
notice of issuance.

     Section 5.13 Rule 145 Affiliates;  Pooling  Letters.  No later than 30 days
following  the date of this  Agreement,  each of the  Company  and Parent  shall
deliver to one another letters identifying all other persons who are at the date
of this  Agreement  or who it is expected  that at the time of the  Stockholders
Meeting may be deemed to be "affiliates" of the Company for purposes of Rule 145
under the  Securities  Act (the "Rule 145  Affiliates").  The Company and Parent
shall  each  use its  reasonable  best  efforts  to  cause  each  person  who is
identified as a Rule 145 Affiliate in such list to deliver to the other party at
least 35 days prior to the Closing Date a written agreement in the form attached
hereto as Exhibit B or C as applicable.

     Section  5.14 Parent Board of  Directors.  The Board of Directors of Parent
shall take such corporate actions as are necessary to provide that, effective at
the Effective Time subject to satisfying the  qualifications of a Director under
Parent's  Articles of  Association,  Ronald L.  Bornhuetter  and another current
non-executive  director of the Company selected by Parent prior to the Effective
Time, after consultation with the Chief Executive Officer of the Company,  shall
become members of the Board of Directors of Parent.

     Section 5.15  Coordination of Dividends.  After the date of this Agreement,
Parent and the Company will coordinate with each other regarding the declaration
of dividends  in respect of the Parent  Ordinary  Shares and the Company  Common
Stock and the record  dates and payment  dates  relating  thereto,  it being the
intention of the parties that  holders of Parent  Ordinary  Shares and shares of
Company  Common  Stock will not  receive two  dividends,  or fail to receive one
dividend,  for any single  calendar  quarter  with  respect  to their  shares of
Company Common Stock and/or the Parent  Ordinary Shares any such holder receives
in exchange therefor in the Merger.

     Section 5.16 Pooling.  During the period from the date of this Agreement to
the Effective Time,  each of Parent,  Sub and the Company will not, and will not
permit any of their respective  subsidiaries to, take any action which (i) would
reasonably  be  expected  to prevent or impede the Merger  from  qualifying  for
pooling-of-interests accounting treatment under United States generally accepted
accounting  principles and  applicable  SEC rules and  regulations or (ii) would
reasonably be expected to prevent the Merger from qualifying as a reorganization
within  the  meaning  of Section  368(a) of the Code.  Nothing in the  foregoing
sentence shall preclude Parent from exercising its rights under the Stock Option
Agreement.


                                   ARTICLE VI

                                   CONDITIONS

     Section 6.1 Conditions to the Obligations of Each Party. The obligations of
the  Company,  on the one  hand,  and  Parent  and Sub,  on the other  hand,  to
consummate  the Merger are  subject to the  satisfaction  (or,  if  permissible,
waiver by the party for whose  benefit such  conditions  exist) of the following
conditions:

     (a) Company Stockholder  Approval.  The Company Stockholder  Approval shall
have been received.

     (b)  No  Injunctions  or  Restraints.   No  temporary   restraining  order,
preliminary  or  permanent  injunction  or other  order  issued  by any court of
competent jurisdiction or other Governmental Entity of competent jurisdiction or
other  legal   restraint  or  prohibition   preventing  or  making  illegal  the
consummation  of the Merger  shall be in  effect;  provided,  however,  that the
parties  hereto  shall  use  their  reasonable  best  efforts  to have  any such
injunction, order, restraint or prohibition vacated.

     (c) HSR and Other Approvals. Any waiting period (and any extension thereof)
or period for any  referral to any body  applicable  to the Merger under the HSR
Act or similar or equivalent  statute or statutes in other  jurisdictions  shall
have expired or been terminated.

     (d) Form S-4.  The Form S-4 shall have been  declared  effective  under the
Securities Act and no stop order suspending the  effectiveness  thereof shall be
in  effect  and no  procedures  for such  purpose  shall be  pending  before  or
threatened by the SEC.

     (e) NYSE Listing. The Parent Ordinary Shares to be issued in the Merger and
the Parent  Ordinary  Shares to be reserved  for  issuance  upon the exercise of
Converted  Stock  Options  shall  have been  approved  for  listing on the NYSE,
subject to official notice of issuance.

     (f) Governmental  and Regulatory  Approvals.  All regulatory  approvals and
other  actions or approvals by any  Governmental  Entity  required to permit the
consummation  of the Merger  (including  those which are not  compulsory but are
desirable to obtain in the  reasonable  opinion of Parent,  Sub and the Company)
(including the insurance regulatory approvals set forth in Section 6.1(f) of the
Company  Disclosure  Letter),  shall have been  obtained  (without  any terms or
conditions to such approvals which would impose material and adverse limitations
on  the  ability  of  Parent  and  its  subsidiaries  (including  the  Surviving
Corporation  following the Merger) to conduct their business after the Effective
Time,  which would require changes to the terms of this Agreement or which would
change the  consideration  payable to stockholders of the Company in the Merger)
and such approvals shall be in full force and effect.

     (g) Pooling.  The Company  shall have  received and delivered to Parent and
Parent's  independent  public  accountants a letter from its independent  public
accountants, dated as of the Closing Date, stating that the Company qualifies as
a "combining company" in accordance with the criteria set forth in Opinion 16 of
the Accounting  Principles  Board and accordingly is a poolable  entity.  Parent
shall have received and  delivered to the Company a letter from its  independent
public  accountants,  dated as of the Closing Date,  stating that accounting for
the  Merger  as a  pooling  of  interests  under  Opinion  16 of the  Accounting
Principles  Board and applicable SEC rules and regulations is appropriate if the
Merger  is  closed  and   consummated  as   contemplated   by  this   Agreement.
Notwithstanding the foregoing, the satisfaction of this Section 6.1(g) shall not
be a condition to the obligations of a party to effect the Merger if the failure
to satisfy this condition results from any action taken or agreed to be taken by
or on behalf of such party.

     Section  6.2  Conditions  to  the   Obligations  of  Parent  and  Sub.  The
obligations  of Parent  and Sub to  consummate  the  Merger  are  subject to the
satisfaction (or waiver by Parent) of the following further conditions:

     (a) Representations  and Warranties.  The representations and warranties of
the Company  qualified as to  materiality  shall be true and accurate (and those
not so qualified shall be true and accurate in all material  respects) as of the
Effective   Time  as  if  made  at  and  as  of  such  time  (except  for  those
representations and warranties that address matters only as of a particular date
or only with  respect to a  specific  period of time which need only be true and
accurate (or true and accurate in all material respects) as of such date or with
respect to such period.  Parent shall have received a  certificate  of the chief
executive  officer and the chief financial  officer of the Company to the effect
set forth in this paragraph.

     (b) Performance of Obligations. The Company and its subsidiaries shall have
performed or complied with all agreements and covenants required to be performed
or complied  with by them under this  Agreement  at or prior to the Closing Date
that are qualified as to materiality and shall have performed or complied in all
material  respects  with all  other  agreements  and  covenants  required  to be
performed by them under this  Agreement at or prior to the Closing Date that are
not so  qualified,  and Parent shall have  received a  certificate  of the chief
executive officer and the chief financial officer of the Company to such effect.

     (c) No Material  Adverse Change.  Since the date of this  Agreement,  there
shall not have  occurred any event,  change,  circumstance,  condition or effect
that shall  have  caused,  or shall be  reasonably  likely to cause,  a Material
Adverse Effect with respect to the Company.

     (d) Closing Documents.  Parent shall receive customary closing documents in
form and substance reasonably satisfactory to it.

     (e)  Consents,  etc.  Parent  shall  have  received  evidence,  in form and
substance reasonably satisfactory to it, that all licenses,  permits,  consents,
approvals, authorizations, qualifications and orders of all third parties listed
on Section 6.2(e) of the Company  Disclosure  Letter have been obtained without,
in the case of third parties, the payment or imposition of any material costs or
obligations.

     (f) No Trigger of Company Rights.  The Company Rights  Agreement shall have
been amended to cause the  expiration  of the Company  Rights at or prior to the
Effective  Time or the Company  Rights  shall have been  redeemed  or  otherwise
terminated, and no trigger event shall have occurred thereunder.

     (g) Tax Opinion.  Parent shall have received an opinion,  dated the Closing
Date, of Simpson Thacher & Bartlett,  counsel to Parent,  to the effect that the
Merger will be treated for U.S.  federal income tax purposes as a reorganization
within  the  meaning  of  Section  368(a) of the Code and that the  transfer  of
Company Common Stock by holders of Company Common Stock, other than holders that
are or will be "5%  transferee  shareholders"  within the  meaning  of  Treasury
regulations  Section  1.367(a)-3(c)(5)-(ii)  pursuant to the Merger will qualify
for an exception under Treasury regulations Section 1.367(a)-3 and, accordingly,
Parent will be treated as a corporation  for U.S.  federal  income tax purposes.
Each  party  agrees  to  make  all  reasonable   representations  and  covenants
reasonably requested in connection with the rendering of such opinion.

     Section 6.3 Conditions to the  Obligations of the Company.  The obligations
of the  Company to  consummate  the Merger are subject to the  satisfaction  (or
waiver by the Company) of the following further conditions:

     (a) Representations  and Warranties.  The representations and warranties of
Parent and Sub qualified as to materiality shall be true and accurate (and those
not so qualified shall be true and accurate in all material  respects) as of the
Effective   Time  as  if  made  at  and  as  of  such  time  (except  for  those
representations and warranties that address matters only as of a particular date
or only with  respect to a  specific  period of time which need only be true and
accurate (or true and accurate in all material respects) as of such date or with
respect to such period.  The Company shall have  received a  certificate  of the
chief executive  officer and the chief financial officer of Parent to the effect
set forth in this paragraph.

     (b)  Performance of  Obligations.  Parent and its  subsidiaries  shall have
performed or complied with all agreements and covenants required to be performed
or complied  with by them under this  Agreement  at or prior to the Closing Date
that are qualified as to materiality and shall have performed or complied in all
material  respects  with all  other  agreements  and  covenants  required  to be
performed by them under this  Agreement at or prior to the Closing Date that are
not so qualified, and the Company shall have received a certificate of the chief
executive officer and the chief financial officer of Parent to such effect.

     (c) No Material  Adverse Change.  Since the date of this  Agreement,  there
shall not have  occurred  and be  continuing  any event,  change,  circumstance,
condition or effect that shall have  caused,  or shall be  reasonably  likely to
cause, a Material Adverse Effect with respect to Parent.

     (d) Closing Documents.  Parent shall receive customary closing documents in
form and substance reasonably satisfactory to it.

     (e) Tax  Opinion.  The Company  shall have  received an opinion,  dated the
Closing Date, of Cadwalader,  Wickersham & Taft, counsel to the Company,  to the
effect that the Merger will be treated for U.S. federal income tax purposes as a
reorganization  within the  meaning  of Section  368(a) of the Code and that the
transfer of Company Common Stock by holders of Company Common Stock,  other than
Company shareholders that are or will be "5% transferee shareholders" within the
meaning of Treasury regulations Section  1.367(a)-3(c)(5)-(ii),  pursuant to the
Merger  will  qualify  for  an  exception  under  Treasury  regulations  Section
1.367(a)-3  and,  accordingly,  Parent will be treated as a corporation for U.S.
federal  income  tax  purposes.   Each  party  agrees  to  make  all  reasonable
representations  and  covenants  reasonably  requested  in  connection  with the
rendering of such opinion.

     Section 6.4 Adjustment of Terms in Certain  Circumstances.  Each of Parent,
Sub and the Company agrees that, in the event that the Merger is not consummated
as a result of the failure to have satisfied or waived any of the conditions set
forth in this Article VI (other than Section 6.1(a),  Section 6.2(a), (b) or (c)
or Section  6.3(a),  (b) or (c)) on the Closing Date, it will negotiate with the
other  parties to this  Agreement  in good  faith,  for a period of 30 days,  to
adjust the terms of this Agreement and the transactions  contemplated  hereby so
as to achieve as nearly as is practicable  the benefits  expected to be received
by each of them upon entering into this Agreement as of the date hereof.  In the
event that the parties are not able to reach an  agreement  with respect to such
an  adjustment,  this Agreement may be terminated by either party as provided in
Section 7.1(i),  unless the party seeking to terminate this Agreement shall have
breached a  representation,  warranty or covenant which breach (or the substance
thereof) shall be the cause of the failure to have satisfied such condition.


                                   ARTICLE VII

                                   TERMINATION

     Section 7.1  Termination.  Anything  herein or  elsewhere  to the  contrary
notwithstanding,  this Agreement may be terminated  and the Merger  contemplated
herein may be abandoned at any time prior to the Effective Time,  whether before
or after the Company Stockholder Approval shall have been received.

     (a) by the mutual written consent of Parent and the Company;

     (b) by either  Parent or the Company if any  Governmental  Entity (i) shall
have  issued an order,  decree or ruling or taken any other  action  permanently
restraining, enjoining or otherwise prohibiting the transactions contemplated by
this Agreement, and such order, decree, ruling or other action shall have become
final and  nonappealable or (ii) shall have failed to issue an order,  decree or
ruling or to take any other action, as applicable,  and such denial of a request
to issue such order, decree,  ruling or take such other action shall have become
final and nonappealable,  in the case of each of (i) and (ii) which is necessary
to fulfill the  conditions  set forth in Sections  6.1(b) and 6.1(f);  provided,
however,  that the right to terminate this  Agreement  under this Section 7.1(b)
shall not be available to any party whose failure to comply with Section 5.4 has
been the cause of such action or failure to act; or

     (c) by  either  Parent or the  Company  if the  Merger  shall not have been
consummated on or before December 31, 1999 (the "Termination  Date");  provided,
that the right to terminate this  Agreement  under this Section 7.1(c) shall not
be available to the party whose failure to fulfill any of its obligations  under
this Agreement has been the cause of or resulted in the failure of the Merger to
occur on or before such date; or

     (d) by Parent or the Company, if the Company Stockholder Approval shall not
have been obtained at a duly held meeting of  stockholders or at any adjournment
thereof; or

     (e) by  Parent,  if the  Company or its Board of  Directors  shall have (i)
withdrawn,   modified  or  amended  in  any   respect   adverse  to  Parent  its
recommendation  of the  adoption of this  Agreement,  (ii) failed as promptly as
practicable  after  the  Form  S-4 is  declared  effective  to  mail  the  Proxy
Statement/Prospectus to its stockholders,  unless such failure was caused by the
actions or inactions of Parent or its  representatives,  or failed to include in
such statement the Company Board Recommendation,  (iii) approved, recommended or
entered  into an  agreement  with respect to, or  consummated,  any  Transaction
Proposal from a person other than Parent or any of its affiliates, (iv) resolved
to do any of the foregoing or (v) in response to the  commencement of any tender
offer or exchange  offer for 10% or more of the  outstanding  the Company Common
Stock,  not recommended  rejection of such tender offer or exchange offer within
ten  business  days after the  commencement  thereof (as such term is defined in
Rule 14d-2 under the Exchange Act);

     (f) (i) by the  Company,  if Parent  breaches  any of its  representations,
covenants or  agreements  contained in this  Agreement and such breach (A) would
permit the Company not to consummate the Merger  pursuant to Sections  6.3(a) or
6.3(b),  and (B) either by its terms cannot be cured by the Closing Date or with
respect to any such breach that is  reasonably  capable of being  remedied,  the
breach is not  remedied  within 20 days after the Company has  furnished  Parent
with written notice of such breach;  or (ii) by Parent,  if the Company breaches
any of its representations,  covenants or agreements contained in this Agreement
and such breach (A) would permit Parent not to consummate the Merger pursuant to
Sections  6.2(a) or 6.2(b),  and (B) either by its terms  cannot be cured by the
Closing  Date or with respect to any such breach that is  reasonably  capable of
being  remedied,  is not remedied  within 20 days after Parent has furnished the
Company with written notice of such breach; or

     (g) By the Company,  if its Board of Directors  determines  at any time, by
the vote of a majority of the members of its entire  board,  during the five-day
period  commencing on the business day following the  Determination  Date,  that
both of the following conditions are satisfied:

          (i) the  Average  Closing  Price on the  Determination  Date of Parent
Ordinary  Shares shall be less than the product of the Starting  Price and 0.85;
and

          (ii) (A) the number  obtained by dividing the Average Closing Price on
the  Determination  Date by the  Starting  Price (such  number being the "Parent
Ratio") shall be less than (B) the number obtained by dividing the Average Index
Price on the Determination  Date by the Average Index Price on the Starting Date
and subtracting 0.15 from such quotient (such number being referred to herein as
the "Index Ratio");

subject,  however,  to the following  four  sentences:  If the Company elects to
exercise its termination right pursuant to the immediately  preceding  sentence,
it shall give prompt  written  notice to Parent which notice shall  specify that
the conditions set forth above have been satisfied; provided that such notice of
election to terminate  may be  withdrawn  at any time within the  aforementioned
five-day  period and the five-day  period  described in the following  sentence.
During the five-day period  commencing  with its receipt of such notice,  Parent
shall have the option of adjusting the Exchange Ratio to equal the lesser of (x)
a number equal to a quotient  (rounded to the nearest  one-ten-thousandth),  the
numerator of which is the product of 0.85,  the Starting  Price and the Exchange
Ratio (as then in effect) and the  denominator  of which is the Average  Closing
Price on the  Determination  Date, and (y) a number equal to a quotient (rounded
to the nearest  one-ten-thousandth),  the  numerator of which is the Index Ratio
multiplied  by the  Exchange  Ratio (as then in effect) and the  denominator  of
which is the Parent  Ratio.  If Parent  makes an  election  contemplated  by the
preceding  sentence  within such five-day  period,  it shall give prompt written
notice to the Company of such election and the revised Exchange Ratio, whereupon
no  termination  shall have  occurred  pursuant to this Section  7.1(g) and this
Agreement  shall remain in effect in  accordance  with its terms  (except as the
Exchange  Ratio  shall  have  been  so  modified),  and any  references  in this
Agreement  to  "Exchange  Ratio"  shall  thereafter  be  deemed  to refer to the
Exchange Ratio as adjusted pursuant to this Section 7.1(g).

     For  purposes of this Section  7.1(g),  the  following  term shall have the
following meanings:

     "Average Closing Price on the Determination  Date" means the average of the
daily closing  prices of Company  Common Stock as reported on the NYSE Composite
Tape (as  reported in The Wall Street  Journal or, if not reported  therein,  in
another mutually acceptable  authoritative  source) for the ten consecutive full
trading  days in which such shares are traded on the NYSE ending at the close of
trading on the Determination Date (the "Company Stock Measurement Period").

     "Average Index Price" means,  as of the Starting Date or the  Determination
Date,  the average of the  weighted  average  (weighted in  accordance  with the
market  capitalization  of such  companies  on the  Starting  Date) of the daily
closing  prices of the common stocks of the companies  composing the Index Group
as reported on the NYSE  Composite  Tape (as reported in The Wall Street Journal
or, if not reported therein,  in another  authoritative  source) on the Starting
Date or for the ten  consecutive  full  trading  days in which  such  shares are
traded on the NYSE ending at the close of trading on the Determination Date.

     "Determination  Date" means the trading day immediately  preceding the date
on which all the  conditions to Closing  (other than  conditions  that, by their
terms, cannot be satisfied until the Closing Date) set forth in Article VI shall
have been  satisfied  or waived,  subject to change as provided in this  Section
7.1(g).

     "Index Group" means the group of the ten companies listed in Section 7.1(g)
of the Company Disclosure Letter. In the event that the common stock of any such
company  ceases to be publicly  traded or a proposal shall be announced for such
company  to be  acquired  or for such  company  to  acquire  another  company or
companies in transactions  with a value  exceeding 25% of the acquiror's  market
capitalization  as of the Starting  Date,  such company will be removed from the
Index  Group,  and the  weights  (which  have  been  determined  based on market
capitalization)  redistributed  proportionately  for purposes of determining the
Average Index Price.

     "Starting  Date" means the first full trading day following the issuance of
a press release announcing the execution of this Agreement.

     "Starting  Price" shall mean the last sale price per Parent  Ordinary Share
on the Starting Date, as reported by the NYSE Composite Tape (as reported in The
Wall Street Journal or, if not reported therein, in another mutually agreed upon
authoritative source).

     If between  the date of this  Agreement  and the  Determination  Date,  the
outstanding  shares of any stock in the Index Group shall have been changed into
a  different   number  of  shares  or  a  different   class  by  reason  of  any
reclassification,   recapitalization,  stock  split,  split-up,  combination  or
exchange  of  shares  or a stock  dividend  or  dividend  payable  in any  other
securities or  extraordinary  cash dividend shall be declared with a record date
within such  period,  or any  similar  event  shall have  occurred,  appropriate
adjustments  shall be made to the Average  Index Price,  as the case may be, for
purposes of this Agreement; or

     (h)  By the  Company,  prior  to the  receipt  of the  Company  Stockholder
Approval,  if its Board of  Directors  approves a Superior  Proposal;  provided,
however,  that (i) the Company  shall have  complied  with Section 5.8, (ii) the
Board of Directors  of the Company  shall have  concluded in good faith,  on the
basis of the advice of its outside legal counsel and  financial  advisors,  that
such proposal is a Superior Proposal and (iii) the Board of Directors shall have
concluded  in good faith,  based upon the advice of its outside  legal  counsel,
that  approving  and  entering  into  an  agreement  in  connection   with,  and
consummating,  such  Superior  Proposal  would  likely be  required  in order to
prevent the Board of  Directors  of the Company  from  breaching  its  fiduciary
duties to the  stockholders of the Company under the DGCL;  provided,  that this
Agreement  may not be  terminated  pursuant to this  Section  7.1(h)  unless (A)
concurrently with, and as a condition to the effectiveness of, such termination,
the  Company  pays to Parent the  Termination  Fee and  Expenses  (as defined in
Sections 7.3(a) and 7.3(b)),  (B) concurrently with such termination the Company
enters  into a  definitive  agreement  with  respect  to, or  consummates,  such
Superior Proposal,  (C) the Company shall have given Parent three business days'
prior  written  notice of the terms and  identity  of the party  proposing  such
Superior  Proposal and of such proposed  termination,  and (D) during such three
business day period, the Company shall have negotiated in good faith with Parent
to permit Parent to make an equivalent  proposal,  which will be accepted by the
Company; or

     (i) By the Company or Parent in accordance  with the  provisions of Section
6.4 hereof.

     Section 7.2 Effect of Termination.  In the event of the termination of this
Agreement as provided in Section 7.1,  written notice thereof shall forthwith be
given to the other party or parties  specifying the provision hereof pursuant to
which such  termination is made, and this Agreement shall forthwith  become null
and void,  and there  shall be no  liability  on the part of Parent,  Sub or the
Company  except (a) for fraud or for willful breach of this  Agreement,  (b) for
the payment of the  Termination  Fee and Expenses in accordance with Section 7.3
and (c) as set forth in this Section 7.2, in Article VIII hereof and in the last
sentence of Section 5.3.

     Section 7.3  Termination  Fees and  Expenses.  (a) In addition to any other
amounts  which may be payable  pursuant to any other  paragraph  of this Section
7.3, the Company shall,  following the termination of this Agreement pursuant to
Sections 7.1(e) or 7.1(h), promptly, but in no event later than one business day
following   written  notice  thereof,   together  with   reasonable   supporting
documentation, reimburse Parent, in an aggregate amount of up to $8,000,000, for
all  out-of-pocket  expenses  and fees  (including  fees payable to all counsel,
accountants,  financial advisors,  financial printers, experts and consultants),
whether  incurred  prior to,  concurrently  with or after the  execution of this
Agreement,   in  connection  with  the  Merger  and  the   consummation  of  all
transactions  contemplated  by this  Agreement  and the Stock  Option  Agreement
(collectively, the "Expenses").

     (b) In the event that this  Agreement is terminated  by Parent  pursuant to
Sections  7.1(e) or 7.1(h),  the Company shall pay to Parent by wire transfer of
immediately  available  funds to an  account  designated  by  Parent on the next
business day following  such  termination  an amount equal to  $38,000,000  (the
"Termination Fee").

     (c) If all of the following events have occurred:

          (i) a Transaction Proposal is commenced,  publicly disclosed, publicly
proposed or  otherwise  communicated  to the Company at any time on or after the
date of this  Agreement  and prior to the  termination  hereof,  and  either (A)
Parent or the Company  terminates this Agreement  pursuant to Sections 7.1(c) or
7.1(d) or (B) Parent terminates this Agreement  pursuant to Section  7.1(f)(ii);
and

          (ii) thereafter, within 18 months of the date of such termination, the
Company enters into a definitive agreement with respect to, or consummates,  any
Transaction  Proposal  (whether or not such Transaction  Proposal was commenced,
publicly disclosed,  publicly proposed or otherwise  communicated to the Company
prior to such termination);

then, the Company shall pay to Parent an amount equal to the Termination Fee and
Expenses  concurrently  with the  earlier of the  execution  of such  definitive
agreement or the consummation of such Transaction Proposal.

     (d) In the event this  Agreement is terminated  by the Company  pursuant to
Section  7.1(i)  following  the failure of the  condition  contained  in Section
6.1(g) to be  satisfied  on the Closing Date (other than as a result of a breach
by the Company of its  representation  and warranty contained in Section 3.22 or
the  covenants  contained in Sections  5.4(c) or 5.16),  Parent shall pay to the
Company  by  wire  transfer  of  immediately  available  funds,  to  an  account
designated by the Company,  on the next  business day  following  notice of such
termination,  together with receipt of reasonable supporting documentation,  the
amount of $8 million as  reimbursement  of  expenses  incurred by the Company in
connection with this Agreement.

 HEREIN AND TO RESALE RESTRICTIONS UNDER THE SECURITIES ACT OF 1933, AS AMENDED


                             STOCK OPTION AGREEMENT


                  STOCK  OPTION  AGREEMENT,  dated as of February  15, 1999 (the
"Agreement"),  by and between NAC Re Corp., a Delaware  corporation  ("Issuer"),
and XL Capital Ltd, a limited liability company organized and incorporated under
the laws of the Cayman Islands ("Grantee").

                                    RECITALS

     A. The Merger Agreement.  Grantee,  Issuer and Dasher  Acquisition Corp., a
Delaware  corporation  ("Sub")  are  concurrently   herewith  entering  into  an
Agreement  and  Plan  of  Merger,  dated  as of the  date  hereof  (the  "Merger
Agreement"),  among Issuer,  Grantee and Sub, providing for, among other things,
the  merger  of Sub  with and into  Issuer,  with  Issuer  being  the  surviving
corporation.

     B.  Condition  to  Merger  Agreement.  As a  condition  and  inducement  to
Grantee's  and Sub's  execution  of the Merger  Agreement,  Grantee and Sub have
required that Issuer agree,  and Issuer has agreed,  to grant Grantee the Option
(as hereinafter defined).

     NOW,  THEREFORE,  in  consideration  of the  foregoing  and the  respective
representations,  warranties,  covenants and  agreements set forth herein and in
the Merger  Agreement,  and  intending to be legally  bound  hereby,  Issuer and
Grantee agree as follows:

     1. Defined Terms.  Capitalized  terms which are used but not defined herein
shall have the meanings ascribed to such terms in the Merger Agreement.

     2. Grant of Option.  Subject to the terms and  conditions set forth herein,
Issuer hereby grants to Grantee an irrevocable option (the "Option") to purchase
up to 1,860,215 shares (as adjusted as set forth herein, the "Option Shares") of
common stock, par value $0.10 per share, of Issuer ("Issuer Common Stock"), at a
purchase price per Option Share (as adjusted as set forth herein,  the "Purchase
Price") equal to $45.3125;  provided that in no event shall the number of Option
Shares  for which  this  Option is  exercisable  exceed  10.1% of the issued and
outstanding  shares of Issuer  Common  Stock.  Each  Option  Share  issued  upon
exercise of the Option shall be accompanied by the applicable  number of Company
Rights as provided in the Company Rights Agreement.

     3. Exercise of Option.

     (a) Holder may  exercise the Option,  in whole or in part,  at any time and
from time to time following the  occurrence of a Purchase Event (as  hereinafter
defined); provided that the Option shall terminate and be of no further force or
effect upon the earliest to occur of (A) the Effective  Time, (B) termination of
the  Merger  Agreement  in  accordance  with  the  terms  thereof  prior  to the
occurrence of a Purchase Event (as hereinafter  defined) or (C) the later of (1)
February 15, 2000 and (2) 6 months after a termination  of the Merger  Agreement
following the  occurrence of a Purchase  Event;  and provided,  further that any
purchase of shares upon  exercise of the Option  shall be subject to  compliance
with applicable law.  Notwithstanding the termination of the Option,  Grantee or
Holder,  as the case may be, shall be entitled to purchase  those Option  Shares
with respect to which it has exercised  the Option in accordance  with the terms
of this  Agreement  prior to the  termination  of the Option.  The term "Holder"
shall  mean the  holder  or  holders  of the  Option  from  time to time,  which
initially is Grantee.  The termination of the Option shall not affect any rights
hereunder which by their terms extend beyond the date of such termination.

     (b) As used herein, a "Purchase Event" means any of the following events:

          (i)  without  Grantee's  prior  written  consent,  Issuer  shall  have
     authorized,   recommended,  publicly  proposed  or  publicly  disclosed  an
     intention to authorize,  recommend or propose,  or entered into one or more
     agreements  with any  person  (other  than  Grantee  or any  subsidiary  of
     Grantee) to effect,  or effected,  in a single  transaction  or a series of
     related transactions, any Transaction Proposal; or

          (ii) any person  (other  than  Grantee or any  subsidiary  of Grantee)
     shall have acquired  beneficial  ownership (as such term is defined in Rule
     13d-3  promulgated  under  the  Exchange  Act) of or the  right to  acquire
     beneficial ownership of, or any "group" (as such term is defined in Section
     13(d)(3) of the Exchange  Act),  other than a group of which Grantee or any
     subsidiary   of  Grantee  is  a  member,   shall  have  been  formed  which
     beneficially owns or has the right to acquire  beneficial  ownership of 10%
     or more of the voting power of Issuer or any of its Subsidiaries; or

          (iii) any person  (other than  Grantee or any  subsidiary  of Grantee)
     shall have  commenced  (as such term is  defined  in Rule  14d-2  under the
     Exchange  Act),  or shall have  filed a  registration  statement  under the
     Securities  Act  with  respect  to, a tender  offer  or  exchange  offer to
     purchase any shares of Issuer Common Stock such that, upon  consummation of
     such  offer,  such  person  would  own or  control  10% or more of the then
     outstanding  shares of Issuer Common Stock (such an offer being referred to
     herein  as a "Tender  Offer"  or an  "Exchange  Offer,"  respectively);  or

          (iv) the Company Stockholder  Approval shall not have been received at
     a duly held meeting of stockholders or at any adjournment  thereof,  or the
     Stockholders  Meeting  shall not have been held or shall have been canceled
     prior to the  termination  of the Merger  Agreement,  in each case after it
     shall have been publicly  disclosed  that any person (other than Grantee or
     any  subsidiary of Grantee)  shall have (A) made, or disclosed an intention
     to make, a Transaction  Proposal,  or (B) filed an  application  or notice,
     whether in draft or final form, with a Governmental  Entity for approval or
     consent to make or consummate a Transaction Proposal; or

          (v) the Issuer or its Board of  Directors  shall  have (A)  withdrawn,
     modified or amended in any respect adverse to Grantee the recommendation of
     Issuer's  Board of  Directors  with  respect to the Merger  Agreement,  (B)
     failed as promptly as practicable after the Form S-4 is declared  effective
     to mail the Proxy Statement/  Prospectus to its  stockholders,  unless such
     failure  was  caused  by  the  actions  or  inactions  of  Grantee  or  its
     representatives,  or failed to include  in such Proxy  Statement/Prospectus
     the  Company  Board  Recommendation  or (C)  resolved  to  take  any of the
     foregoing actions; or

          (vi) the Merger  Agreement  shall have been  terminated  in accordance
     with its terms under any  circumstances in which the Termination Fee is or,
     upon the occurrence of the events specified  therein,  would become payable
     as provided in Section 7.3(b) or 7.3(c) of the Merger Agreement.

As used in this Agreement, "person" shall have the meaning specified in Sections
3(a)(9) and 13(d)(3) of the Exchange Act.

     (c) Issuer shall notify  Grantee  promptly in writing of the  occurrence of
any Purchase Event, it being understood that the giving of such notice by Issuer
shall not be a condition to the right of Holder to exercise the Option.

     (d) In the event  Holder  wishes to exercise  the Option,  it shall send to
Issuer a written  notice  (the date of which  being  herein  referred  to as the
"Notice  Date")  specifying  (i) the total number of Option Shares it intends to
purchase  pursuant to such  exercise  and (ii) a place and date not earlier than
three business days nor later than 60 business days from the Notice Date for the
closing (the "Closing") of such purchase (the "Closing Date");  provided that if
the Closing cannot be consummated by reason of any applicable Law or the need to
obtain any necessary approvals or consents of applicable  Governmental Entities,
the period of time that otherwise  would run pursuant to this sentence shall run
instead from the date on which such  restriction on consummation  has expired or
been terminated; and provided,  further, without limiting the foregoing, that if
prior  notification  or  application  to,  approval of or  authorization  by any
Governmental  Entity is required in connection with such purchase,  Issuer shall
use all reasonable  efforts to cooperate with the Holder in the prompt filing of
the  required  notice or  application  for  approval or  authorization,  and the
Closing shall occur immediately  following the date on which such approvals have
been obtained or any required  notification or waiting periods have expired. Any
exercise  of the  Option  shall be deemed to occur on the Notice  Date  relating
thereto.

     (e)  Notwithstanding  Section  3(d),  in no event shall any Closing Date be
more than 12 months after the related Notice Date, and if the Closing Date shall
not have  occurred  within 12 months  after the  related  Notice Date due to the
failure  to obtain  any such  required  approval,  the  exercise  of the  Option
effected  on the Notice Date shall be deemed to have  expired.  In the event (i)
Holder  receives  official  notice that an approval of any  Governmental  Entity
required for the purchase of Option Shares will not be issued or granted or (ii)
a Closing Date shall not have occurred within 12 months after the related Notice
Date due to the failure to obtain any such required  approval,  Grantee shall be
entitled to exercise the Option  (whether or not the Option would have otherwise
terminated)  in  connection  with the  resale  of Issuer  Common  Stock or other
securities  pursuant to a registration  statement as provided in Section 11. The
provisions  of this  Section  3 and  Section  4  shall  apply  with  appropriate
adjustments to any such exercise.

     4. Payment and Delivery of Certificates.

     (a) On each Closing Date,  Holder shall (i) pay to Issuer,  in  immediately
available  funds  by  wire  transfer  to a bank  account  designated  by  Issuer
(provided  that the  failure or refusal of Issuer to  designate  a bank  account
shall not preclude the Holder from  exercising  the Option),  an amount equal to
the Purchase Price  multiplied by the number of Option Shares to be purchased on
such Closing Date,  and (ii) present and surrender  this Agreement to the Issuer
at the address of the Issuer specified in Section 14(f).

     (b) At each  Closing,  simultaneously  with  the  delivery  of  immediately
available funds and surrender of this Agreement as provided in Section 4(a), (i)
Issuer shall deliver to Holder (A) a certificate  or  certificates  representing
the Option Shares to be purchased at such Closing,  which Option Shares shall be
free and clear of all Liens and subject to no preemptive  rights, and (B) if the
Option is exercised in part only, an executed new agreement  with the same terms
as this Agreement  evidencing the right to purchase the balance of the shares of
Issuer  Common Stock  purchasable  hereunder,  and (ii) Holder shall  deliver to
Issuer a letter  agreeing  that  Holder  shall  not  offer to sell or  otherwise
dispose of such Option Shares in violation of  applicable  federal and state law
or of the provisions of this Agreement.

     (c) In addition to any other  legend  that is required by  applicable  law,
certificates  for the Option Shares  delivered at each Closing shall be endorsed
with a restrictive legend which shall read substantially as follows:

     THE TRANSFER OF THE STOCK  REPRESENTED  BY THIS  CERTIFICATE  IS SUBJECT TO
     RESTRICTIONS  ARISING UNDER THE  SECURITIES  ACT OF 1933,  AS AMENDED,  AND
     PURSUANT TO THE TERMS OF A STOCK OPTION  AGREEMENT DATED AS OF FEBRUARY 15,
     1999.  A COPY OF SUCH  AGREEMENT  WILL BE  PROVIDED  TO THE  HOLDER  HEREOF
     WITHOUT  CHARGE UPON  RECEIPT BY THE  SECRETARY  OF THE ISSUER OF A WRITTEN
     REQUEST THEREFOR.

It is understood and agreed that (i) the portion of the above legend relating to
the  Securities  Act shall be removed by delivery of  substitute  certificate(s)
without such legend if such Option Shares have been  registered  pursuant to the
Securities  Act,  such  Option  Shares  have  been  sold in  reliance  on and in
accordance with Rule 144 under the Securities Act or Holder shall have delivered
to Issuer a copy of a letter from the staff of the SEC, or an opinion of counsel
in form and substance reasonably  satisfactory to Issuer and its counsel, to the
effect that such legend is not required for purposes of the Securities Act, (ii)
the  reference to  restrictions  pursuant to this  Agreement in the above legend
shall be removed by delivery of substitute certificate(s) without such reference
if the Option Shares evidenced by certificate(s)  containing such reference have
been sold or  transferred  in compliance  with the  provisions of this Agreement
under  circumstances  that do not require the  retention of such  reference  and
(iii) such  legend  shall be removed in its  entirety if the  conditions  in the
preceding clauses (i) and (ii) are both satisfied.

     (d) Upon the giving by Holder to Issuer of the  written  notice of exercise
of the Option  provided for under  Section  3(d),  the tender of the  applicable
Purchase Price in immediately  available  funds and the tender of this Agreement
to  Issuer,  Holder  shall be deemed to be the holder of record of the shares of
Issuer Common Stock issuable upon such exercise,  notwithstanding that the stock
transfer books of Issuer shall then be closed or that certificates  representing
such  shares of Issuer  Common  Stock shall not then be  actually  delivered  to
Holder. Issuer shall pay all expenses, and any and all federal,  foreign, state,
and local taxes and other  charges  that may be payable in  connection  with the
preparation, issuance and delivery of stock certificates under this Section 4(d)
in the name of Holder or its assignee, transferee, or designee.

     (e) Issuer agrees (i) that it shall at all times maintain,  free from Liens
and preemptive or similar rights, sufficient authorized but unissued or treasury
shares of Issuer Common Stock ("Available Authorized Shares") so that the Option
may be exercised without  additional  authorization of Issuer Common Stock after
giving effect to all other options,  warrants,  convertible securities and other
rights to purchase Issuer Common Stock then outstanding,  (ii) that it will not,
by charter amendment or through reorganization, recapitalization, consolidation,
merger,   dissolution,   liquidation,   spin-off,  sale  of  assets  or  similar
transaction,  or by any  other  voluntary  act,  avoid  or  seek  to  avoid  the
observance or performance of any of the covenants,  agreements,  stipulations or
conditions to be observed or performed  hereunder by Issuer,  (iii)  promptly to
take all action as may from time to time be required  (including  (A)  complying
with all premerger  notification,  reporting and waiting period requirements and
(B) in the event prior approval or  authorization of or notice or application to
any  Governmental  Entity is  necessary  before  the  Option  may be  exercised,
cooperating  fully with Holder in  preparing  such  applications  or notices and
providing  such  information to such  Governmental  Entity as it may require) in
order to permit Holder to exercise the Option and Issuer duly and effectively to
issue shares of the Issuer Common Stock  pursuant  hereto,  and (iv) promptly to
take all  action  provided  herein to  protect  the  rights  of  Holder  against
dilution. Notwithstanding the foregoing, it is understood that as of the date of
this Agreement,  Issuer does not have Available  Authorized Shares sufficient to
permit the exercise of the Option in full.  Issuer  covenants  and agrees to use
its best  efforts to cause its Board of Directors to  designate,  in  accordance
with its certificate of incorporation  and the DGCL, a series of preferred stock
of Issuer having terms such that each 1/100 of a share of such  preferred  stock
(a  "Preferred  Share")  shall have  voting,  dividend  and  liquidation  rights
equivalent to one share of Issuer  Common Stock.  In the event of an exercise of
the Option for a number of shares of Issuer Common Stock in excess of the number
of Available Authorized Shares (such excess, the "Excess Shares"), Grantee shall
be entitled to purchase a number of such Preferred Shares equal to the number of
Excess Shares at a price per 1/100th of a Preferred  Share equal to the Purchase
Price. Any such Preferred Shares so issued pursuant to the terms hereof shall be
"Option  Shares" and shares of "Issuer Common Stock" for all purposes under this
Agreement and all references herein to "Option Shares" and "Issuer Common Stock"
shall include the Preferred Shares.

     5.  Representations and Warranties of Issuer.  Issuer hereby represents and
warrants to Grantee (and Holder, if different than Grantee) as follows:

     (a)  Corporate  Authority.  Issuer has the  requisite  corporate  power and
authority  to  execute  and  deliver  this   Agreement  and  to  consummate  the
transactions  contemplated  hereby; the execution and delivery of this Agreement
and,  subject to  receiving  any  necessary  approvals  or  authorizations  from
Governmental Entities, the consummation of the transactions  contemplated hereby
have been duly and validly  authorized by the Board of Directors of Issuer,  and
no other corporate  proceedings on the part of Issuer are necessary to authorize
this Agreement or to consummate the transactions so contemplated; this Agreement
has been duly and validly  executed and  delivered by Issuer and  (assuming  due
authorization,  execution  and  delivery  by  Grantee)  constitutes  a valid and
binding obligation of Issuer,  enforceable against Issuer in accordance with its
terms, except that (i) such enforcement may be subject to applicable bankruptcy,
insolvency,  fraudulent  conveyance,  moratorium or other  similar laws,  now or
hereinafter  in effect,  affecting  creditors'  rights  generally,  and (ii) the
remedy of specific  performance  and  injunctive  and other  forms of  equitable
relief may be subject to equitable  defenses and to the  discretion of the court
before which any proceeding therefor may be brought.

     (b) Shares  Reserved  for  Issuance;  Capital  Stock.  Issuer has taken all
necessary  corporate action to authorize and reserve and permit it to issue, and
at all times from the date hereof  through the  termination of this Agreement in
accordance with its terms, will have reserved for issuance, upon the exercise of
the Option,  that number of shares of Issuer Common Stock  (including  Preferred
Shares)  equal to the maximum  number of shares of Issuer Common Stock and other
shares and  securities  which are at any time and from time to time  purchasable
upon exercise of the Option, and all such shares and other securities (including
Preferred  Shares),   upon  issuance  pursuant  to  the  Option,  will  be  duly
authorized, validly issued, fully paid and nonassessable,  and will be delivered
free and clear of all Liens (other than those created by this Agreement) and not
subject to any preemptive or other similar rights.

     (c)  No  Violations.  The  execution,  delivery  and  performance  of  this
Agreement  does not and will not, and the  consummation  by Issuer of any of the
transactions  contemplated hereby will not, constitute or result in (A) a breach
or  violation  of, or a default  under,  its  certificate  of  incorporation  or
by-laws, or the comparable governing instruments of any of its subsidiaries,  or
(B) a breach or violation of, or a default under, any Company Agreement (with or
without  the  giving of  notice,  the lapse of time or both) or under any Law or
governmental  or  non-governmental  permit or  license to which it or any of its
subsidiaries  is  subject,  that  would in any case  give any other  person  the
ability to prevent or enjoin  Issuer's  performance  under this Agreement in any
material respect.

     (d) Board  Action.  The Board of  Directors  of Issuer  has  approved  this
Agreement  and the  consummation  of the  transactions  contemplated  hereby  as
required under Section 203 of the DGCL and any other  applicable  state takeover
laws so that  any such  state  takeover  laws do not and will not  apply to this
Agreement or any of the transactions contemplated hereby (including the purchase
of shares of Issuer Common Stock pursuant to this Agreement).

     (e) Rights  Amendment.  The Company  Rights  Agreement  has been amended to
provide that neither  Grantee nor any Holder will become an  "Acquiring  Person"
and that no "Stock  Acquisition Date" or "Distribution  Date" (as such terms are
defined in the Company Rights Agreement) will occur as a result of the approval,
execution  or  delivery  of  this  Agreement  or  the  Merger  Agreement  or the
consummation of the transactions contemplated hereby and thereby,  including the
acquisition  of shares of Issuer  Common Stock by Grantee or Holder  pursuant to
this Agreement.

     6. Representations and Warranties of Grantee. Grantee hereby represents and
warrants to Issuer as follows:

     (a) Corporate Authority.  Grantee has full corporate power and authority to
enter into this Agreement and, subject to obtaining the approvals referred to in
this Agreement,  to consummate the transactions  contemplated by this Agreement;
the  execution  and  delivery  of this  Agreement  and the  consummation  of the
transactions  contemplated  hereby have been duly  authorized  by all  necessary
corporate  action  on the part of  Grantee;  and this  Agreement  has been  duly
executed and delivered by Grantee and (assuming due authorization, execution and
delivery by Issuer)  constitutes a valid and binding  obligation of the Grantee,
enforceable against the Grantee in accordance with its terms.

     (b) Purchase Not for  Distribution.  Any Option Shares or other  securities
acquired by Grantee or Holder upon exercise of the Option will not be taken with
a view to the  public  distribution  thereof  and  will  not be  transferred  or
otherwise  disposed  of  except  in a  transaction  registered  or  exempt  from
registration under the Securities Act.

     7. Adjustment upon Changes in Issuer Capitalization, Etc.

     (a) In the event of any change from time to time in Issuer Common Stock and
any  other  shares  or  securities  subject  to the  Option by reason of a stock
dividend,  subdivision,  spinoff, stock split, split-up, merger,  consolidation,
recapitalization, combination, exchange of shares, distribution on or in respect
of the  Issuer  Common  Stock that  would be  prohibited  under the terms of the
Merger  Agreement,  or  similar  transaction,  the type and  number of shares or
securities  subject to the Option,  and the Purchase  Price  therefor,  shall be
adjusted  appropriately,  and proper  provision  shall be made in the agreements
governing such transaction,  so that Holder shall receive,  upon exercise of the
Option, the economic benefits provided hereunder, including the number and class
of shares or other  securities  or property  that Holder would have  received in
respect of Issuer  Common  Stock if the Option  had been  exercised  immediately
prior  to such  event,  or the  record  date  therefor,  as  applicable.  If any
additional  shares  of  Issuer  Common  Stock are  issued  or  otherwise  become
outstanding  after the date of this  Agreement  (other than pursuant to an event
described in the first  sentence of this  Section  7(a) or upon  exercise of the
Option) the number of shares of Issuer  Common Stock subject to the Option shall
be adjusted so that, after such issuance, it, together with any shares of Issuer
Common Stock previously  issued pursuant  hereto,  equals 10.1% of the number of
shares of Issuer Common Stock then issued and outstanding, without giving effect
to any shares  subject to or issued  pursuant to the  Option.  In the event that
Issuer  issues or agrees to issue any shares of Issuer  Common Stock (other than
as  permitted  by the  Merger  Agreement)  at a price  per  share  less than the
Purchase Price (as theretofore adjusted pursuant to this Section 7) the Purchase
Price shall be reduced to equal such lesser price.  No provision of this Section
7 shall be deemed  to affect or  change,  or  constitute  authorization  for any
violation of, any of the covenants, agreements, representations or warranties in
the Merger Agreement.

     (b) Without limiting the parties'  relative rights,  remedies,  liabilities
and obligations under the Merger Agreement or this Agreement,  in the event that
Issuer shall enter into an agreement  (other than the Merger  Agreement)  (i) to
consolidate  with or merge into any  person,  other  than  Grantee or one of its
Subsidiaries,  and shall not be the continuing or surviving  corporation of such
consolidation or merger, (ii) to permit any person, other than Grantee or one of
its  Subsidiaries,  to merge into Issuer and Issuer shall be the  continuing  or
surviving corporation, but, in connection with such merger, the then outstanding
shares of Issuer  Common Stock shall be changed  into or  exchanged  for another
class or series of stock or other  securities  of Issuer or any other  person or
cash or any other  property or the  outstanding  shares of Issuer  Common  Stock
immediately prior to such merger shall,  after such merger,  represent less than
75% of the outstanding  shares and share equivalents having general voting power
of  the  merged  company,  or  (iii)  to  sell  or  otherwise  transfer  all  or
substantially  all of its  assets or the assets of its  subsidiaries  taken as a
whole,  in one transaction or a series of related  transactions,  to any person,
other than Grantee or one of its Subsidiaries,  then, and in each such case, the
agreement  governing such transaction  shall make proper  provisions so that the
Option shall,  upon the  consummation of any such transaction and upon the terms
and conditions set forth herein,  be converted into, or exchanged for, an option
(the  "Substitute  Option"),  at the  election  of  Holder,  of  either  (x) the
Acquiring Corporation (as hereinafter defined), (y) any person that controls the
Acquiring Corporation,  or (z) in the case of a merger described in clause (ii),
Issuer (such person being referred to as "Substitute Option Issuer").

     (c) The Substitute Option shall have the same terms as the Option, provided
that, if the terms of the Substitute  Option cannot,  for legal reasons,  be the
same as the Option,  such terms shall be as similar as possible  and in no event
less  advantageous to Holder,  and provided,  further that the Substitute Option
shall be  exercisable  immediately  upon  issuance  without the  occurrence of a
further  Purchase  Event.  Substitute  Option  Issuer  shall  also enter into an
agreement with Holder in  substantially  the same form as this Agreement,  which
shall be applicable to the Substitute Option.

     (d) The Substitute Option shall be exercisable for such number of shares of
Substitute  Common  Stock (as  hereinafter  defined) as is equal to the Assigned
Value (as  hereinafter  defined)  multiplied  by the  number of shares of Issuer
Common Stock for which the Option was  theretofore  exercisable,  divided by the
Average Price (as  hereinafter  defined).  The exercise  price of the Substitute
Option per share of  Substitute  Common Stock (the  "Substitute  Option  Price")
shall then be equal to the Purchase Price  multiplied by a fraction in which the
numerator  is the number of shares of Issuer  Common  Stock for which the Option
was  theretofore  exercisable  and the  denominator  is the  number of shares of
Substitute Common Stock for which the Substitute Option is exercisable.

     (e) The following terms have the meanings indicated:

          (i) "Acquiring Corporation" shall mean (x) the continuing or surviving
     corporation  of a  consolidation  or merger  with  Issuer  (if  other  than
     Issuer),  (y)  Issuer in a merger  in which  Issuer  is the  continuing  or
     surviving  person,  or (z) the  transferee of all or  substantially  all of
     Issuer's assets (or the assets of its subsidiaries taken as a whole).

          (ii)  "Assigned  Value"  shall  mean the  highest of (w) the price per
     share of Issuer  Common Stock at which a Tender Offer or an Exchange  Offer
     therefor has been made,  (x) the price per share of Issuer  Common Stock to
     be paid by any third party  pursuant to an agreement  with Issuer,  (y) the
     highest  closing  price for  shares  of  Issuer  Common  Stock  within  the
     six-month  period  immediately  preceding  the  date on which  the  merger,
     consolidation,  asset sale or other transaction in question is consummated,
     and (z) in the  event  of a sale of all or  substantially  all of  Issuer's
     assets (or of the assets of its subsidiaries as a whole) an amount equal to
     (I) the sum of the price paid in such sale for such  assets and the current
     market  value  of the  remaining  assets  of  Issuer,  as  determined  by a
     nationally recognized  investment banking firm selected by Holder,  divided
     by (II) the number of shares of Issuer  Common  Stock  outstanding  at such
     time. In calculating  the Assigned  Value, in the event that a Tender Offer
     or an Exchange  Offer is made for Issuer  Common  Stock or an  agreement is
     entered into for a merger or consolidation  involving  consideration  other
     than  cash,  the value of the  securities  or other  property  issuable  or
     deliverable  in exchange for Issuer  Common Stock shall be  determined by a
     nationally recognized investment banking firm selected by Holder.

          (iii) "Average  Price" shall mean the average closing price of a share
     of Substitute  Common Stock on the NYSE (or if such Substitute Common Stock
     is not  listed on the  NYSE,  the  average  closing  price on the  National
     Association of Securities  Dealers  Automated  Quotation  System or, if the
     shares of Substitute  Common Stock are not quoted thereon,  the highest bid
     price per share as quoted on the  principal  trading  market on which  such
     shares are traded as  reported  by a  recognized  source)  for the one year
     immediately preceding the date of consummation of the consolidation, merger
     or sale in question,  but in no event higher than the closing  price of the
     shares of Substitute Common Stock on the day preceding such  consolidation,
     merger or sale;  provided  that if Issuer is the  issuer of the  Substitute
     Option,  the Average  Price shall be  computed  with  respect to a share of
     common stock issued by Issuer,  by the person merging into Issuer or by any
     company which controls such person, as Holder may elect.

          (iv) "Substitute  Common Stock" shall mean the shares of capital stock
     (or similar equity  interest) with the greatest  voting power in respect of
     the  election  of  directors  (or  persons  similarly  responsible  for the
     direction of the business and affairs) of the Substitute Option Issuer.

     (f) In no event,  pursuant to any of the  foregoing  paragraphs,  shall the
Substitute  Option be  exercisable  for more than 10.1% of the  aggregate of the
shares  of  Substitute  Common  Stock  outstanding  prior  to  exercise  of  the
Substitute  Option. In the event that the Substitute Option would be exercisable
for more than 10.1% of the  aggregate of the shares of  Substitute  Common Stock
but for the  limitation in the first  sentence of this Section 7(f),  Substitute
Option Issuer shall make a cash payment to Holder equal to the excess of (i) the
value of the  Substitute  Option  without giving effect to the limitation in the
first sentence of this Section 7(f) over (ii) the value of the Substitute Option
after  giving  effect to the  limitation  in the first  sentence of this Section
7(f).  This  difference in value shall be determined by a  nationally-recognized
investment banking firm selected by Holder.

     (g) Issuer shall not enter into any  transaction  described in Section 7(b)
unless the  Acquiring  Corporation  and any person that  controls the  Acquiring
Corporation  assume in writing all the obligations of Issuer  hereunder and take
all other actions that may be necessary so that the provisions of this Section 7
are given full force and effect (including,  without limitation, any action that
may be  necessary so that the holders of the other shares of common stock issued
by Substitute Option Issuer are not entitled to exercise any rights by reason of
the issuance or exercise of the  Substitute  Option and the shares of Substitute
Common  Stock  are  otherwise  in no way  distinguishable  from or  have  lesser
economic value (other than any diminution in value  resulting from the fact that
the Substitute  Common Stock are restricted  securities,  as defined in Rule 144
under the Securities Act or any successor provision) than other shares of common
stock issued by Substitute Option Issuer).

     8. Repurchase at the Option of Holder.

     (a) At the  request  of  Holder at any time (i)  commencing  upon the first
occurrence  of a  Repurchase  Event (as  defined in Section  8(d)) and ending 18
months  immediately  thereafter  and (ii) for 30  business  days  following  the
occurrence  of either of the events set forth in clauses (i) and (ii) of Section
3(e) (but solely as to shares of Issuer  Common  Stock with respect to which the
required  approval was not received,  Issuer (or any successor) shall repurchase
from Holder (x) the Option and (y) all shares of Issuer  Common Stock  purchased
by Holder  pursuant  hereto with  respect to which  Holder  then has  beneficial
ownership. The date on which Holder exercises its rights under this Section 8 is
referred to as the  "Request  Date".  Such  repurchase  shall be at an aggregate
price (the "Section 8 Repurchase Consideration") equal to the sum of:

          (i) the  aggregate  Purchase  Price  paid by Holder  for any shares of
     Issuer Common Stock  acquired  pursuant to the Option with respect to which
     Holder then has beneficial ownership;

          (ii) the  excess,  if any,  of (x) the  Applicable  Price (as  defined
     below) for each share of Issuer  Common Stock over (y) the  Purchase  Price
     (subject to adjustment  pursuant to Section 7), multiplied by the number of
     shares of Issuer Common Stock with respect to which the Option has not been
     exercised; and

          (iii) the excess,  if any, of the  Applicable  Price over the Purchase
     Price  (subject to adjustment  pursuant to Section 7) paid (or, in the case
     of Option  Shares with respect to which the option has been  exercised  but
     the  Closing  Date has not  occurred,  payable) by Holder for each share of
     Issuer Common Stock with respect to which the Option has been exercised and
     with respect to which Holder then has beneficial  ownership,  multiplied by
     the number of such shares.

     (b) If Holder  exercises  its rights  under this  Section 8, Issuer  shall,
within 5 business  days after the Request  Date,  pay the  Section 8  Repurchase
Consideration to Holder in immediately  available  funds, and  contemporaneously
with  such  payment,  Holder  shall  surrender  to  Issuer  the  Option  and the
certificates  evidencing the shares of Issuer Common Stock purchased  thereunder
with respect to which  Holder then has  beneficial  ownership,  and Holder shall
warrant that it has sole record and beneficial  ownership of such shares and the
Option and that the same are then free and clear of all  Liens.  Notwithstanding
the  foregoing,  to the extent  that prior  notification  to or  approval of any
Governmental  Entity is  required in  connection  with the payment of all or any
portion of the Section 8 Repurchase Consideration, Holder shall have the ongoing
option to revoke its request for  repurchase  pursuant to Section 8, in whole or
in part, or to require that Issuer deliver from time to time that portion of the
Section 8 Repurchase Consideration that it is not then so prohibited from paying
and  promptly  file  the  required   notice  or  application  for  approval  and
expeditiously process the same (and each party shall cooperate with the other in
the  filing of any such  notice or  application  and the  obtaining  of any such
approval)  and the  period of time that  would  otherwise  run  pursuant  to the
preceding  sentence  for the payment of the portion of the Section 8  Repurchase
Consideration  shall run instead from the date on which, as the case may be, (i)
any required  notification  period has expired or been  terminated  or (ii) such
approval has been obtained and, in either event,  any requisite  waiting  period
shall  have  passed.  If any  Governmental  Entity  disapproves  of any  part of
Issuer's proposed  repurchase  pursuant to this Section 8, Issuer shall promptly
give notice of such fact to Holder.  If any  Governmental  Entity  prohibits the
repurchase (and Issuer hereby undertakes to use all reasonable efforts to obtain
all required approvals from Governmental Entities to accomplish such repurchase)
in part but not in whole,  then  Holder  shall  have the right (i) to revoke the
repurchase request or (ii) to the extent permitted by such Governmental  Entity,
determine whether the repurchase should apply to the Option and/or Option Shares
and to what  extent  to each,  and  Holder  shall  thereupon  have the  right to
exercise  the Option as to the number of Option  Shares for which the Option was
exercisable  at the Request Date less the sum of the number of shares covered by
the  Option in  respect  of which  payment  has been made  pursuant  to  Section
8(a)(ii) and the number of shares  covered by the portion of the Option (if any)
that has been repurchased;  whereupon,  in the case of clause (ii), Issuer shall
promptly  (x)  deliver to the Holder that  portion of the  Section 8  Repurchase
Consideration  Price  that  Issuer is not  prohibited  from  delivering  and (y)
deliver to the Holder, as appropriate, either (A) a new Agreement evidencing the
right of the Holder to  purchase  that number of shares of Issuer  Common  Stock
obtained  by  multiplying  the  number of  shares of Common  Stock for which the
surrendered  Agreement was  exercisable at the time of delivery of the notice of
repurchase  by a fraction,  the  numerator  of which is the Section 8 Repurchase
Consideration less the portion thereof  theretofore  delivered to the Holder and
the  denominator  of which is the Section 8 Repurchase  Consideration,  or (B) a
certificate  for the Option Shares it is then so prohibited  from  repurchasing;
provided,  that if the Option  shall have  terminated  prior to the date of such
notice or shall be scheduled to terminate at any time before the expiration of a
period  ending on the  thirtieth  business  day after  such date,  Holder  shall
nonetheless  have the right so to  exercise  the Option or  exercise  its rights
under Section 9 until the expiration of such period of 30 business days.  Holder
shall notify Issuer of its determination  under the preceding sentence within 10
business days of receipt of notice of disapproval of the repurchase.

     (c) For  purposes  of this  Agreement,  the  "Applicable  Price"  means the
highest of (i) the highest  price per share of Issuer  Common Stock paid for any
such share by the person or groups described in Section 8(d)(i),  (ii) the price
per share of Issuer  Common Stock  received by holders of Issuer Common Stock in
connection with any merger or other business combination  transaction  described
in Section 7(b)(i),  7(b)(ii) or 7(b)(iii),  and (iii) the highest closing sales
price per share of Issuer  Common Stock quoted on the NYSE (or if Issuer  Common
Stock is not listed on the NYSE,  the highest  closing price per share as quoted
on the Nasdaq  National  Market  System or, if the shares of Issuer Common Stock
are not  quoted  thereon,  the  highest  bid  price  per  share as quoted on the
principal  trading  market in which  such  shares are  traded as  reported  by a
recognized  source)  during the 40 business  days  preceding  the Request  Date;
provided,  however,  that in the  event of a sale of less  than all of  Issuer's
assets, the Applicable Price shall be the sum of the price paid in such sale for
such assets and the current  market value of the  remaining  assets of Issuer as
determined  by a  nationally  recognized  investment  banking  firm  selected by
Holder,  divided by the number of shares of the Issuer Common Stock  outstanding
at the time of such sale. If the  consideration to be offered,  paid or received
pursuant  to either of the  foregoing  clauses  (i) or (ii)  shall be other than
cash,  the value of such  consideration  shall be determined in good faith by an
independent  nationally  recognized  investment banking firm selected by Holder,
which determination shall be conclusive for all purposes of this Agreement.

     (d) As used  herein,  a  "Repurchase  Event"  shall occur if (i) any person
(other than Grantee or any subsidiary of Grantee) shall have acquired beneficial
ownership  of (as such  term is  defined  in Rule  13d-3  promulgated  under the
Exchange Act), or the right to acquire  beneficial  ownership of, or any "group"
(as such term is defined  under the  Exchange  Act) shall have been formed which
beneficially  owns or has the right to acquire  beneficial  ownership of, 35% or
more of the then  outstanding  shares of Issuer  Common  Stock,  (ii) any of the
transactions  described  in Section  7(b)(i),  7(b)(ii)  or  7(b)(iii)  has been
consummated or (iii) Issuer has entered into an agreement  pursuant to which any
of the transactions described in Section 7(b)(i), 7(b)(ii) or 7(b)(iii) could or
will be consummated.

     9. Repurchase of Substitute Option.

     (a) At the  request  of  Holder at any time (i)  commencing  upon the first
occurrence  of a Substitute  Repurchase  Event (as defined in Section  9(d)) and
ending 18 months immediately  thereafter and (ii) for 30 business days following
the  occurrence  of either of the events  set forth in  clauses  (i) and (ii) of
Section 3(e) (but solely as to shares of Substitute Common Stock with respect to
which the required approval was not received),  Substitute Option Issuer (or any
successor)  shall  repurchase  from  Holder (x) the Option and (y) all shares of
Substitute  Common  Stock  purchased by Holder  pursuant  hereto with respect to
which Holder then has beneficial  ownership.  The date on which Holder exercises
its rights under this Section 9 is referred to as the "Section 9 Request  Date".
Such  repurchase  shall be at an  aggregate  price (the  "Section  9  Repurchase
Consideration") equal to the sum of:

          (i) the  aggregate  Purchase  Price  paid by Holder  for any shares of
     Substitute  Common Stock acquired  pursuant to the  Substitute  Option with
     respect to which Holder then has beneficial ownership;

          (ii) the excess,  if any, of (x) the Substitute  Applicable  Price (as
     defined  below)  for each  share of  Substitute  Common  Stock over (y) the
     Purchase Price (subject to adjustment pursuant to Section 7), multiplied by
     the number of shares of  Substitute  Common Stock with respect to which the
     Substitute Option has not been exercised; and

          (iii) the excess, if any, of the Substitute  Applicable Price over the
     Purchase Price  (subject to adjustment  pursuant to Section 7) paid (or, in
     the case of Option  Shares (for purposes of this  Agreement,  Option Shares
     shall  include  shares of  Substitute  Common Stock and related  securities
     subject to the  Substitute  Option)  with  respect to which the  Substitute
     Option has been  exercised but the Closing Date has not occurred,  payable)
     by Holder for each share of  Substitute  Common Stock with respect to which
     the  Substitute  Option has been exercised and with respect to which Holder
     then has beneficial ownership, multiplied by the number of such shares.

     (b) If Holder exercises its rights under this Section 9, Substitute  Option
Issuer shall,  within 5 business days after the Section 9 Request Date,  pay the
Section 9 Repurchase Consideration to Holder in immediately available funds, and
contemporaneously with such payment, Holder shall surrender to Substitute Option
Issuer the  Substitute  Option  and the  certificates  evidencing  the shares of
Substitute  Common Stock purchased  thereunder with respect to which Holder then
has beneficial  ownership,  and Holder shall warrant that it has sole record and
beneficial  ownership of such shares and the Substitute Option and that the same
are then free and clear of all  Liens.  Notwithstanding  the  foregoing,  to the
extent that prior  notification  to or approval  of any  Governmental  Entity is
required in  connection  with the payment of all or any portion of the Section 9
Repurchase  Consideration,  Holder  shall have the ongoing  option to revoke its
request for repurchase pursuant to Section 9, in whole or in part, or to require
that  Substitute  Option  Issuer  deliver  from time to time that portion of the
Section 9 Repurchase Consideration that it is not then so prohibited from paying
and  promptly  file  the  required   notice  or  application  for  approval  and
expeditiously process the same (and each party shall cooperate with the other in
the  filing of any such  notice or  application  and the  obtaining  of any such
approval)  and the  period of time that  would  otherwise  run  pursuant  to the
preceding  sentence  for the payment of the portion of the Section 9  Repurchase
Consideration  shall run instead from the date on which, as the case may be, (i)
any required  notification  period has expired or been  terminated  or (ii) such
approval has been obtained and, in either event,  any requisite  waiting  period
shall  have  passed.  If any  Governmental  Entity  disapproves  of any  part of
Substitute  Option  Issuer's  proposed  repurchase  pursuant to this  Section 9,
Substitute Option Issuer shall promptly give notice of such fact to Holder (such
notice a "Notice of  Disapproval").  If any  Governmental  Entity  prohibits the
repurchase (and Substitute Option Issuer hereby undertakes to use all reasonable
efforts  to  obtain  all  required  approvals  from  Governmental   Entities  to
accomplish such repurchase) in part but not in whole, then Holder shall have the
right (i) to revoke the  repurchase  request or (ii) to the extent  permitted by
such Governmental  Entity,  determine whether the repurchase should apply to the
Substitute  Option and/or  Option Shares and to what extent to each,  and Holder
shall  thereupon  have the right to  exercise  the  Substitute  Option as to the
number of Option Shares for which the Substitute  Option was  exercisable at the
Section 9  Request  Date less the sum of the  number  of shares  covered  by the
Substitute  Option in respect of which payment has been made pursuant to Section
9(a)(ii)  and the  number of shares  covered by the  portion  of the  Substitute
Option  (if any)  that has been  repurchased;  whereupon,  in the case of clause
(ii),  Substitute  Option  Issuer shall  promptly (x) deliver to the Holder that
portion of the Section 9 Repurchase  Consideration  Price that Substitute Option
Issuer is not  prohibited  from  delivering  and (y) deliver to the  Holder,  as
appropriate, either (A) a new Stock Option Agreement evidencing the right of the
Holder to purchase that number of shares of Substitute  Common Stock obtained by
multiplying  the  number  of  shares of  Substitute  Common  Stock for which the
surrendered  Stock Option  Agreement was  exercisable at the time of delivery of
the notice of repurchase by a fraction,  the numerator of which is the Section 9
Repurchase  Consideration less the portion thereof theretofore  delivered to the
Holder and the denominator of which is the Section 9 Repurchase Consideration or
(B)  a  certificate  for  the  Option  Shares  it is  then  so  prohibited  from
repurchasing;  provided,  further,  that if the  Substitute  Option  shall  have
terminated  prior to the date of such notice or shall be  scheduled to terminate
at any time before the  expiration of a period ending on the thirtieth  business
day after such date, Grantee shall nonetheless have the right so to exercise the
Substitute Option or exercise its rights under Section 9 until the expiration of
such period of 30 business days. Holder shall notify Substitute Option Issuer of
its  determination  under the  preceding  sentence  within ten business  days of
receipt of Notice of Disapproval of the repurchase.

      (c) For purposes of this  Agreement,  the  "Substitute  Applicable  Price"
means the highest of (i) the highest price per share of Substitute  Common Stock
paid for any such share by the person or groups  described  in Section  9(d)(i),
(ii) the price per share of  Substitute  Common  Stock  received  by  holders of
Substitute  Common  Stock in  connection  with  any  merger  or  other  business
combination transaction described in Section 7(b)(i),  7(b)(ii) or 7(b)(iii), or
(iii) the highest  closing  sales  price per share of  Substitute  Common  Stock
quoted on the NYSE (or if the Substitute Common Stock is not listed on the NYSE,
the highest  closing  price per share as quoted the Nasdaq NMS or, if the shares
of Substitute Common Stock are not quoted thereon,  the highest bid price on the
principal trading market in which such shares are traded by a recognized source)
during the 40 business  days  preceding  the Section 9 Request  Date;  provided,
however,  that in the  event  of a sale of less  than all of  Substitute  Option
Issuer's assets,  the Substitute  Applicable Price shall be the sum of the price
paid in such sale for such assets and the current  market value of the remaining
assets of Substitute  Option  Issuer as  determined  by a nationally  recognized
investment  banking firm selected by Holder,  divided by the number of shares of
the  Substitute  Common  Stock  outstanding  at the  time of such  sale.  If the
consideration  to be  offered,  paid  or  received  pursuant  to  either  of the
foregoing  clauses  (i) or (ii) shall be other  than in cash,  the value of such
consideration  shall be  determined in good faith by an  independent  nationally
recognized investment banking firm selected by Holder, which determination shall
be conclusive for all purposes of this Agreement.

      (d) As used herein, a "Substitute Repurchase Event" shall occur if (i) any
person  (other than Grantee or any  subsidiary  of Grantee)  shall have acquired
beneficial ownership of (as such term is defined in Rule 13d-3 promulgated under
the  Exchange  Act),  or the right to acquire  beneficial  ownership  of, or any
"group" (as such term is defined  under the Exchange Act) shall have been formed
which beneficially owns or has the right to acquire beneficial ownership of, 35%
or more of the then outstanding  shares of Substitute  Common Stock, (ii) any of
the transactions  described in Section  7(b)(i),  7(b)(ii) or 7(b)(iii) has been
consummated  or (iii)  Substitute  Option  Issuer has entered  into an agreement
pursuant to which any of the transactions described in Section 7(b)(i), 7(b)(ii)
or 7(b)(iii) could or will be consummated.  If the  consideration  paid or to be
paid to holders of Substitute  Common Stock in the  transactions  referred to in
either of the foregoing  clauses (i) or (ii) shall be other than cash, the value
of such  consideration  shall be  determined  in good  faith  by an  independent
nationally   recognized  investment  banking  firm  selected  by  Holder,  which
determination shall be conclusive for all purposes of this Agreement.

     (e) All  references  to  "Issuer",  "Issuer  Common  Stock" and "Section 8"
contained  herein shall also be deemed to be  references to  "Substitute  Option
Issuer," "Substitute Common Stock" and "Section 9" respectively.

     10. Right of First Refusal. If, within one year after the Closing Date (but
not  thereafter),  Grantee proposes to sell all or any part of the Option Shares
in a transaction  not required to be registered  under the Securities Act (other
than in a  transfer  by  operation  of law  upon  consummation  of a  merger  or
consolidation,  in a tender or  exchange  offer or in a sale under Rule 144 or a
successor  provision  under  the  Securities  Act),  it shall  give  Issuer  the
opportunity, in the following manner, to purchase such Option Shares:

     (a)  Grantee  shall give  notice to Issuer in writing of its intent to sell
Option Shares (a "Disposition  Notice"),  specifying the number of Option Shares
to be sold, the price and the material terms of any agreement  relating thereto.
The Disposition Notice may be given at any time.

     (b) Issuer  shall have the right,  exercisable  by written  notice given to
Grantee  within 5  business  days  after  receipt of a  Disposition  Notice,  to
purchase  all,  but not less than all,  of the Option  Shares  specified  in the
Disposition  Notice at the price set  forth in the  Disposition  Notice.  If the
purchase price specified in the  Disposition  Notice includes any property other
than cash,  the  purchase  price to be paid by Issuer shall be an amount of cash
equal to the sum of (i) the cash  included in the  purchase  price plus (ii) the
fair market value of such other property at the date of the Disposition  Notice.
If such other property  consists of securities  with an existing  public trading
market,  the  average of the last sale  prices for such  securities  on the five
trading days ending five days prior to the date of the Disposition  Notice shall
be used as the  fair  market  value of such  property.  If such  other  property
consists of  something  other than cash or  securities  with an existing  public
trading  market and at the time of the  closing  referred  to in  paragraph  (c)
below,  agreement on the value of such other property has not been reached,  the
average of the closing prices for the Issuer's  common stock on the five trading
days ending five days prior to the date of the Disposition  Notice shall be used
as the per share  purchase  price;  provided,  however,  that promptly after the
closing,  Grantee and Issuer or its  designee,  as the case may be, shall settle
any additional  amounts to be paid or returned as a result of the  determination
of fair market  value of such other  property  made by a  nationally  recognized
investment  banking firm  selected by Issuer and  approved by Grantee  within 30
days of the  closing.  Such  determination  shall be final  and  binding  on all
parties hereto.

      (c) If Issuer exercises its right of first refusal hereunder,  the closing
of the  purchase of the Option  Shares with respect to which such right has been
exercised  shall take place within five  business  days after the notice of such
exercise;  provided,  however,  that at any  time  prior to the  closing  of the
purchase  of Option  Shares  hereunder,  Grantee may  determine  not to sell the
Option  Shares  and revoke  the  Disposition  Notice  and,  by so doing,  cancel
Issuer's right of first refusal with respect  thereto.  Issuer shall pay for the
Option Shares in immediately available funds.

     (d) If Issuer does not exercise its right of first refusal hereunder within
the  time  specified  for  such  exercise,  Grantee  shall  be free  for 90 days
following  the  expiration  of such time for  exercise  to sell or enter into an
agreement to sell the Option Shares specified in the Disposition  Notice, at the
price  specified in the  Disposition  Notice or any price in excess  thereof and
otherwise on substantially  the same terms set forth in the Disposition  Notice;
provided, that if such sale is not consummated within such 90-day period (unless
the approval or consent of a Governmental  Entity is required to consummate such
sale,  in which case the 90-day period shall not be deemed to have expired until
after such approval or consent shall have been granted),  then the provisions of
this Section 10 will again apply to the sale of such Option Shares.

     11. Registration Rights.

     (a) Demand Registration Rights.  Issuer shall, subject to the conditions of
Section  11(c)  below,  if requested  by any Holder,  including  Grantee and any
permitted  transferee  ("Selling  Stockholder"),  as  expeditiously  as possible
prepare, file and keep current a registration statement under the Securities Act
if such  registration  is  necessary  in  order  to  permit  the  sale or  other
disposition of any or all shares of Issuer Common Stock or other securities that
have been acquired by or are issuable to the Selling  Stockholder  upon exercise
of the  Option  in  accordance  with  the  intended  method  of  sale  or  other
disposition  stated  by the  Selling  Stockholder  in such  request,  including,
without limitation,  a "shelf"  registration  statement under Rule 415 under the
Securities Act or any successor provision, and Issuer shall use its best efforts
to qualify such shares or other  securities for sale under any applicable  state
securities laws.

      (b)  Piggyback  Registration  Rights.  If  Issuer  at any time  after  the
exercise of the Option  proposes to register  any shares of Issuer  Common Stock
under the Securities Act in connection with an  underwritten  public offering of
such Issuer  Common  Stock,  Issuer will  promptly  give  written  notice to the
Selling  Stockholders of its intention to do so and, upon the written request of
any Selling  Stockholder  given within 30 days after  receipt of any such notice
(which  request  shall  specify  the  number of shares  of Issuer  Common  Stock
intended  to be  included in such  underwritten  public  offering by the Selling
Stockholder),  Issuer will cause all such shares for which a Selling Stockholder
requests participation in such registration, to be so registered and included in
such underwritten public offering;  provided,  however, that Issuer may elect to
not cause such shares to be so registered  (i) if in the  reasonable  good faith
opinion of the underwriters for such offering,  the inclusion of all such shares
by the Selling Stockholder would materially interfere with the marketing of such
offering (in which case Issuer shall register as many shares as possible without
materially interfering with the marketing of the offering),  or (ii) in the case
of a registration solely to implement an employee benefit plan or a registration
filed on Form S-4 of the Securities  Act or any successor  Form. If some but not
all the shares of Issuer  Common  Stock with  respect to which Issuer shall have
received  requests  for  registration  pursuant to this  Section  11(b) shall be
excluded from such  registration,  Issuer shall make  appropriate  allocation of
shares to be  registered  among the  Selling  Stockholders  desiring to register
their shares pro rata in the proportion  that the number of shares  requested to
be  registered  by each such  Selling  Stockholder  bears to the total number of
shares requested to be registered by all such Selling Stockholders then desiring
to have Issuer Common Stock registered for sale.

     (c)  Conditions to Required  Registration.  Issuer shall use all reasonable
efforts to cause each registration  statement referred to in Section 11(a) above
to become effective and to obtain all consents or waivers of other parties which
are  required  therefor  and to  keep  such  registration  statement  effective;
provided,  however,  that  Issuer may delay any  registration  of Option  Shares
required  pursuant  to Section  11(a) above for a period not  exceeding  90 days
provided Issuer shall in good faith determine that any such  registration  would
adversely  affect an offering or  contemplated  offering of other  securities by
Issuer,  and Issuer  shall not be required to register  Option  Shares under the
Securities Act pursuant to Section 11(a) above:

          (i) prior to the earliest of (a)  termination of the Merger  Agreement
     pursuant  to  Article  VII  thereof,  (b)  failure  to obtain  the  Company
     Stockholder Approval, and (c) a Purchase Event;

          (ii) on more than two occasions during any calendar year;

          (iii)  within  90 days  after  the  effective  date of a  registration
     referred  to  in  Section  11(b)  above   pursuant  to  which  the  Selling
     Stockholder or Selling Stockholders concerned were afforded the opportunity
     to  register  such  shares  under the  Securities  Act and such shares were
     registered as requested;

          (iv)  unless  a  request   therefor  is  made  to  Issuer  by  Selling
     Stockholders  that  hold at least  25% or more of the  aggregate  number of
     Option Shares (including shares of Issuer Common Stock and other securities
     issuable upon exercise of the Option) then outstanding; and

          (v) after  such  date as all the  Option  Shares  may be resold in one
     transaction pursuant to Rule 144 of the Securities Act (or any successor or
     similar rule or act).

     In addition to the foregoing,  Issuer shall not be required to maintain the
effectiveness  of any  registration  statement  after the expiration of one year
from the effective  date of such  registration  statement.  Issuer shall use all
reasonable efforts to make any filings, and take all steps, under all applicable
state  securities  laws to the  extent  necessary  to  permit  the sale or other
disposition  of the Option Shares so registered in accordance  with the intended
method of distribution for such shares; provided, however, that Issuer shall not
be required to consent to general  jurisdiction or qualify to do business in any
state where it is not otherwise  required to so consent to such  jurisdiction or
to so qualify to do business. If requested by any such Holder in connection with
such  registration,  Issuer shall become a party to any  underwriting  agreement
relating to the sale of such shares, but only to the extent of obligating itself
in respect of  representations,  warranties,  indemnities  and other  agreements
customarily  included  in  secondary  offering  underwriting  agreements.   Upon
receiving  any request  under this Section 11 from any Holder,  Issuer agrees to
send a copy  thereof  to any other  person  known to Issuer  to be  entitled  to
registration  rights under this Section 11, in each case by promptly mailing the
same,  postage  prepaid,  to the  address of record of the  persons  entitled to
receive such copies.

     (d) Expenses.  Except where  applicable  state law prohibits such payments,
Issuer will pay all expenses (including, without limitation,  registration fees,
qualification  fees, blue sky fees and expenses (including the fees and expenses
of counsel), legal fees and expenses, including the reasonable fees and expenses
of one counsel to the holders whose Option Shares are being registered, printing
expenses and the costs of special audits or "cold comfort" letters,  expenses of
underwriters,  excluding  discounts  and  commissions  but  including  liability
insurance  if  Issuer  so  desires  or the  underwriters  so  require,  and  the
reasonable  fees and expenses of any  necessary  special  experts) in connection
with each  registration  pursuant to Section 11(a) or 11(b) above (including the
related  offerings  and  sales  by  holders  of  Option  Shares)  and all  other
qualifications,  notifications or exemptions  pursuant to Section 11(a) or 11(b)
above.

     (e)  Indemnification.  In connection  with any  registration  under Section
11(a) or 11(b) above Issuer hereby  indemnifies  the Selling  Stockholders,  and
each  underwriter  thereof,  including  each person,  if any, who controls  such
holder or underwriter  within the meaning of Section 15 of the  Securities  Act,
against all expenses,  losses,  claims,  damages and  liabilities  caused by any
untrue,  or alleged  untrue,  statement  of a  material  fact  contained  in any
registration  statement  or  prospectus  or  notification  or offering  circular
(including any amendments or supplements thereto) or any preliminary prospectus,
or caused by any omission, or alleged omission, to state therein a material fact
required to be stated  therein or necessary to make the  statements  therein not
misleading,  except  insofar  as  such  expenses,  losses,  claims,  damages  or
liabilities  of such  indemnified  party are caused by any untrue  statement  or
alleged untrue  statement  that was included by Issuer in any such  registration
statement or prospectus or  notification  or offering  circular  (including  any
amendments or  supplements  thereto) in reliance  upon and in  conformity  with,
information  furnished in writing to Issuer by such indemnified  party expressly
for use therein, and Issuer and each officer, director and controlling person of
Issuer  shall  be  indemnified  by each  such  Selling  Stockholder,  or by such
underwriter,  as the case may be, for all such expenses, losses, claims, damages
and liabilities  caused by any untrue,  or alleged untrue,  statement,  that was
included  by  Issuer  in  any  such  registration  statement  or  prospectus  or
notification  or offering  circular  (including  any  amendments or  supplements
thereto) in reliance  upon,  and in conformity  with,  information  furnished in
writing to Issuer by such Selling  Stockholder or such underwriter,  as the case
may be, expressly for such use.

     Promptly  upon receipt by a party  indemnified  under this Section 11(e) of
notice of the  commencement  of any action  against  such  indemnified  party in
respect  of  which  indemnity  or  reimbursement   may  be  sought  against  any
indemnifying party under this Section 11(e), such indemnified party shall notify
the indemnifying  party in writing of the  commencement of such action,  but the
failure  so to  notify  the  indemnifying  party  shall  not  relieve  it of any
liability  which it may  otherwise  have to any  indemnified  party  under  this
Section 11(e) unless the failure so to notify the  indemnified  party results in
substantial prejudice thereto. In case notice of commencement of any such action
shall be given to the  indemnifying  party as above provided,  the  indemnifying
party  shall be  entitled  to  participate  in and,  to the  extent it may wish,
jointly with any other  indemnifying  party  similarly  notified,  to assume the
defense  of such  action  at its own  expense,  with  counsel  chosen  by it and
satisfactory to such  indemnified  party.  The indemnified  party shall have the
right to employ  separate  counsel  in any such  action and  participate  in the
defense  thereof,  but the  fees  and  expenses  of  such  counsel  (other  than
reasonable costs of investigation) shall be paid by the indemnified party unless
(i) the indemnifying  party either agrees to pay the same, (ii) the indemnifying
party fails to assume the defense of such action with  counsel  satisfactory  to
the  indemnified  party,  or (iii) the  indemnified  party has been  advised  by
counsel that one or more legal  defenses  may be  available to the  indemnifying
party that may be contrary to the interest of the  indemnified  party,  in which
case the  indemnifying  party  shall be  entitled  to assume the defense of such
action notwithstanding its obligation to bear fees and expenses of such counsel.
No  indemnifying  party shall be liable for any settlement  entered into without
its consent, which consent may not be unreasonably withheld.

     If the indemnification provided for in this Section 11(e) is unavailable to
a party otherwise entitled to be indemnified in respect of any expenses, losses,
claims,  damages or liabilities referred to herein, then the indemnifying party,
in lieu of indemnifying such party otherwise  entitled to be indemnified,  shall
contribute  to the amount paid or payable by such party to be  indemnified  as a
result  of  such  expenses,  losses,  claims,  damages  or  liabilities  in such
proportion  as is  appropriate  to reflect  the  relative  benefits  received by
Issuer,  the Selling  Stockholders and the underwriters from the offering of the
securities and also the relative fault of Issuer,  the Selling  Stockholders and
the  underwriters  in connection with the statements or omissions which resulted
in such expenses,  losses, claims, damages or liabilities,  as well as any other
relevant  equitable  considerations.  The amount paid or payable by a party as a
result of the expenses,  losses,  claims,  damages and  liabilities  referred to
above shall be deemed to include any legal or other fees or expenses  reasonably
incurred by such party in connection with  investigating or defending any action
or claim;  provided,  however,  that in no case shall any Selling Stockholder be
responsible,  in the  aggregate,  for any  amount in excess of the net  offering
proceeds  attributable to its Option Shares included in the offering.  No person
guilty of fraudulent  misrepresentation  (within the meaning of Section 11(f) of
the Securities  Act) shall be entitled to  contribution  from any person who was
not guilty of such fraudulent misrepresentation. Any obligation by any holder to
indemnify shall be several and not joint with other holders.

     In  connection  with any  registration  pursuant to Section  11(a) or 11(b)
above, Issuer and each Selling Stockholder (other than Grantee) shall enter into
an agreement containing the indemnification provisions of this Section 11(e).

     (f)  Miscellaneous  Reporting.  Issuer  shall  comply  with  all  reporting
requirements and will do all such other things as may be necessary to permit the
expeditious  sale at any time of any Option  Shares by the Selling  Stockholders
thereof in accordance with and to the extent permitted by any rule or regulation
promulgated by the SEC from time to time,  including,  without limitation,  Rule
144.  Issuer  shall at its expense  provide the  Selling  Stockholders  with any
information  necessary  in  connection  with the  completion  and  filing of any
reports or forms  required to be filed by them under the  Securities  Act or the
Exchange Act, or required  pursuant to any state securities laws or the rules of
the NASD or any stock exchange.

     (g) Issue  Taxes.  Issuer will pay all stamp taxes in  connection  with the
issuance and the sale of the Option Shares and in  connection  with the exercise
of the  Option,  and  will  save  the  Selling  Stockholders  harmless,  without
limitation as to time,  against any and all liabilities with respect to all such
taxes.

     12. Quotation:  Listing.  If Issuer Common Stock or any other securities to
be acquired in  connection  with the exercise of the Option are then  authorized
for  quotation  or trading  or listing on the NYSE,  the Nasdaq NMS or any other
securities exchange or securities quotation system,  Issuer, upon the request of
Holder,  will  promptly  file an  application,  if required,  to  authorize  for
quotation  or trading or listing the shares of Issuer  Common Stock or any other
securities  (including  Preferred  Shares) to be acquired  upon  exercise of the
Option  on the  NYSE,  the  Nasdaq  NMS or such  other  securities  exchange  or
securities  quotation  system  and will use all  reasonable  efforts  to  obtain
approval, if required, of such quotation or listing as soon as practicable.

     13. Division of Option.  This Agreement (and the Option granted hereby) are
exchangeable,  without expense,  at the option of Holder,  upon presentation and
surrender  of this  Agreement  at the  principal  office  of  Issuer,  for other
Agreements providing for Options of different denominations entitling the holder
thereof to purchase in the  aggregate the same number of shares of Issuer Common
Stock purchasable  hereunder.  The terms "Agreement" and "Option" as used herein
include  any other Stock  Option  Agreement  and related  Options for which this
Agreement  (and the Option  granted  hereby) may be  exchanged.  Upon receipt by
Issuer of evidence reasonably satisfactory to it of the loss, theft, destruction
or mutilation of this Agreement, and (in the case of loss, theft or destruction)
of reasonably satisfactory indemnification,  and upon surrender and cancellation
of this Agreement, if mutilated, Issuer will execute and deliver a new Agreement
of like tenor and date.  Any such new  Agreement  executed and  delivered  shall
constitute an additional  contractual  obligation on the part of Issuer, whether
or not the Agreement so lost,  stolen,  destroyed or mutilated shall at any time
be enforceable by anyone.

     14. Limitation of Grantee Profit. (a)  Notwithstanding  any other provision
herein,  in no event shall  Grantee's  Total  Profit (as defined  below)  exceed
$38,000,000,  exclusive of any reimbursement of expenses pursuant to Section 7.3
of the Merger  Agreement  (the  "Maximum  Profit"),  and, if it otherwise  would
exceed such amount, Grantee, at its sole discretion, shall either (i) reduce the
number of shares subject to the Option (and any Substitute Option), (ii) deliver
to Issuer, or the Substitute Issuer, as the case may be, for cancellation shares
of Issuer Common Stock or Substitute  Common Stock, as the case may be (or other
securities into which such Option Shares are converted or exchanged),  (iii) pay
cash to  Issuer,  or the  Substitute  Issuer,  as the case  may be,  or (iv) any
combination of the foregoing,  so that Grantee's  actually realized Total Profit
shall not exceed the Maximum  Profit  after  taking into  account the  foregoing
actions.

     (b) For purposes of this  Agreement,  "Total  Profit"  shall mean:  (i) the
aggregate  amount of (A) the  excess  of (x) the net cash  amounts  received  by
Grantee  pursuant  to a sale of Option  Shares  (or  securities  into which such
shares are  converted or exchanged)  to any  unaffiliated  third party within 12
months  after the  exercise  of the  Option,  over (y) the  Grantee's  aggregate
purchase  price  for such  Option  Shares  (or other  securities),  plus (B) all
amounts received by Grantee on the transfer of the Option (including pursuant to
Section 8),  plus (C) all  equivalent  amounts  with  respect to the  Substitute
Option  (including  pursuant to Section  9),  plus (D) all  amounts  received by
Grantee   pursuant  to  Section  7.3  of  the  Merger   Agreement   (other  than
reimbursement in respect of Expenses), minus (ii) all amounts of cash previously
paid to Issuer  pursuant to this Section 14 plus the value of the Option  Shares
(or other securities)  previously delivered to Issuer for cancellation  pursuant
to this Section 14.

     (c) Notwithstanding any other provision of this Agreement,  nothing in this
Agreement shall affect the ability of Grantee to receive,  nor relieve  Issuer's
obligation  to pay,  any  payment  provided  for in  Section  7.3 of the  Merger
Agreement;  provided  that if and to the extent  the Total  Profit  received  by
Grantee  would  exceed the Maximum  Profit  following  receipt of such  payment,
Grantee  shall be obligated to comply with the terms of Section  14(a) within 30
days of the latest of (i) the date of receipt of such payment,  (ii) the date of
receipt of the net cash by  Grantee  pursuant  to the sale of Option  Shares (or
securities  into which such Option  Shares are  converted or  exchanged)  to any
unaffiliated  party  within 12 months  after the  exercise  of this  Option with
respect to such  Option  Shares,  (iii) the date of receipt of net cash from the
disposition of the Option or Substitute Option, as the case may be, and (iv) the
date of receipt of  equivalent  amounts  pursuant to the sale of the  Substitute
Option or shares of Substitute Common Stock (or other securities into which such
Substitute Common Stock is converted or exchanged).

     (d) For  purposes of paragraph  (a) of this  Section and clause  (b)(ii) of
this Section,  the value of any Option  Shares  delivered to Issuer shall be the
Assigned  Value of such  Option  Shares and the value of any  Substitute  Common
Stock delivered to Substitute Issuer shall be the Substitute Applicable Price of
such Substitute Common Stock.

     15. Miscellaneous.

     (a)  Expenses.  Except  as  otherwise  provided  herein  or in  the  Merger
Agreement,  each of the parties hereto shall bear and pay all costs and expenses
incurred by it or on its behalf in connection with the transactions contemplated
hereunder, including, without limitation, fees and expenses of its own financial
consultants, investment bankers, accountants and counsel.

     (b) Waiver and Amendment.  Any provision of this Agreement may be waived at
any time by the party that is entitled to the benefits of such  provision.  This
Agreement may not be modified,  amended, altered or supplemented except upon the
execution and delivery of a written  agreement  executed by the parties  hereto.
The  failure of any party to this  Agreement  to assert any of its rights  under
this  Agreement or otherwise  shall not  constitute a waiver of such rights.  No
single or partial exercise of any right,  remedy,  power or privilege  hereunder
shall  preclude  any other or further  exercise  thereof or the  exercise of any
other right, remedy,  power or privilege.  Any waiver shall be effective only in
the specific instance and for the specific purpose for which given and shall not
constitute a waiver to any  subsequent or other  exercise of any right,  remedy,
power or privilege hereunder.

     (c) Entire  Agreement:  No Third-Party  Beneficiaries;  Severability.  This
Agreement,  together  with the  Merger  Agreement  and the other  documents  and
instruments  referred  to herein and  therein,  between  Grantee  and Issuer (i)
constitutes  the  entire  agreement  and  supersedes  all prior  agreements  and
understandings,  both written and oral,  between the parties with respect to the
subject  matter  hereof and (ii) is not intended to confer upon any person other
than the parties hereto or their  respective  successors and assigns (other than
any  transferees  of the  Option  Shares  or any  permitted  transferee  of this
Agreement  pursuant  to Section  15(h)) any  rights,  remedies,  obligations  or
liabilities hereunder.  If any term, provision,  covenant or restriction of this
Agreement is held by a court of competent jurisdiction or Governmental Entity to
be invalid,  void or  unenforceable,  the  remainder  of the terms,  provisions,
covenants  and  restrictions  of this  Agreement  shall remain in full force and
effect  and shall in no way be  affected  impaired  or  invalidated.  If for any
reason such court or  Governmental  Entity  determines  that the Option does not
permit Holder to acquire,  or does not require  Issuer to  repurchase,  the full
number of shares of Issuer  Common  Stock as  provided  in  Section 2 (as may be
adjusted  herein),  it is the  express  intention  of Issuer to allow  Holder to
acquire or to require  Issuer to repurchase  such lesser number of shares as may
be permissible without any amendment or modification hereof.

     (d)  Governing  Law.  This  Agreement  shall be governed  and  construed in
accordance with the laws of the State of Delaware.

     (e) Descriptive Headings. The descriptive headings contained herein are for
convenience  of  reference  only and shall not affect in any way the  meaning or
interpretation of this Agreement.

     (f) Notices.  All notices and other  communications  hereunder  shall be in
writing and shall be deemed  given if  delivered  personally,  telecopied  (with
confirmation)  or  mailed  by  registered  or  certified  mail  (return  receipt
requested) to the parties at the addresses set forth in the Merger Agreement (or
at such other address for a party as shall be specified by like notice).

     (g) Counterparts.  This Agreement and any amendments hereto may be executed
in two  counterparts,  each of  which  shall  be  considered  one  and the  same
agreement and shall become effective when both counterparts have been signed, it
being understood that both parties need not sign the same counterpart.

     (h) Assignment.  Neither this Agreement nor any of the rights, interests or
obligations  hereunder  or under  the  Option  shall be  assigned  by any of the
parties  hereto  (whether by  operation of law or  otherwise)  without the prior
written consent of the other party, except that Holder may assign this Agreement
to a  wholly-owned  subsidiary  of Holder  and  Holder  may  assign  its  rights
hereunder in whole or in part after the occurrence of a Purchase Event.  Subject
to the preceding  sentence,  this Agreement shall be binding upon,  inure to the
benefit of and be enforceable by the parties and their respective successors and
assigns.

     (i) Further  Assurances.  In the event of any exercise of the Option by the
Holder,  Issuer and the Holder shall execute and deliver all other documents and
instruments and take all other action that may be reasonably  necessary in order
to consummate the transactions provided for by such exercise.

     (j) Specific Performance.  The parties hereto agree that this Agreement may
be enforced by either party through specific performance,  injunctive relief and
other equitable relief.  Both parties further agree to waive any requirement for
the securing or posting of any bond in connection with the obtaining of any such
equitable  relief  and that this  provision  is without  prejudice  to any other
rights  that the  parties  hereto  may  have for any  failure  to  perform  this
Agreement.

     (k) Rights Plan.  Until the Option has been exercised or terminated in full
and Grantee or Holder no longer holds any Option Shares, Issuer shall not amend,
modify or waive any provision of the Company Rights  Agreement or take any other
action which would cause Grantee or Holder to be an "Acquiring Person", or which
would cause a "Stock  Acquisition  Date" or  "Distribution  Date",  or any event
specified  in Section 11 or 13 of the Company  Rights  Agreement  or any similar
event with respect to the Company Rights to occur, by reason of the existence or
exercise  (in  whole or in part) of the  Option,  the  beneficial  ownership  by
Grantee or Holder or any of their respective "Affiliates" or "Associates" of any
of the Option Shares, or the consummation of the other transactions contemplated
hereby  (all  terms  in  quotes  are  used  as  defined  in the  Company  Rights
Agreement). This covenant shall also apply to any Substitute Option or shares of
Substitute  Common Stock issued in respect  thereof,  and to any securities into
which any Option Shares or Substitute Common Stock are converted or exchanged.

     (l) Consent to  Jurisdiction  and Service of Process.  Any suit,  action or
proceeding  seeking to enforce any provision of, or based on any matter  arising
out of or in connection with, this Agreement or the transactions contemplated by
this  Agreement  may be brought  against any of the parties in any federal court
located in the State of Delaware or any Delaware  state  court,  and each of the
parties hereto consents to the non-exclusive jurisdiction of such courts (and of
the  appropriate  appellate  courts  therefrom)  in any  such  suit,  action  or
proceeding  and waives any objection to venue laid therein.  Process in any such
suit, action or proceeding may be served on any party anywhere in the world and,
without limiting the generality of the foregoing,  each party hereto agrees that
service of process upon such party at the address  referred to in Section 8.4 of
the Merger Agreement, together with written notice of such service to such party
shall be deemed effective service of process upon such party.

                 XL CAPITAL LTD AND NAC RE CORPORATION ANNOUNCE
                               INTENTION TO MERGE

     NAC RE SHAREHOLDERS TO RECEIVE 0.915 SHARES OF XL CAPITAL IN ALL STOCK
                                  TRANSACTION

HAMILTON,  BERMUDA  AND  GREENWICH,  CT,  FEBRUARY  16,  1999 - XL  Capital  Ltd
(NYSE:XL)  ("XL") and NAC Re Corporation  (NYSE:NRC)  ("NAC Re") announced today
that the two companies have signed a definitive  agreement whereby XL and NAC Re
will merge in an all stock  transaction.  In addition,  all  outstanding  NAC Re
indebtedness will be assumed by XL.

Under the terms of the transaction, shareholders of NAC Re will receive 0.915 XL
shares  for each NAC Re share in a  tax-free  exchange  of  shares  that will be
accounted for as a pooling of interests under U.S. generally accepted accounting
principles  ("GAAP").  The  transaction is subject to the approval of the NAC Re
shareholders,   expiration   of  the   applicable   waiting   period  under  the
Hart-Scott-Rodino  Antitrust Improvements Act, receipt of insurance,  regulatory
approvals and other customary closing conditions. It is expected that the merger
will be completed by late second calendar quarter or early third quarter of this
year.  The Boards of Directors of NAC Re and XL have each voted  unanimously  to
approve the  transaction.  Based on XL's closing price of $60.50 on the New York
Stock Exchange on Friday,  February 12, 1999,  each NAC Re share would be valued
at $55.36.

"NAC Re is the premier  broker-market  reinsurer  in the United  States and will
be a major cornerstone of XL's business," stated Brian M. O'Hara,  President and
Chief Executive  Officer of XL Capital Ltd. "NAC Re will become our platform for
the United States,  the largest  insurance and reinsurance  market in the world.
Its  reinsurance   portfolio   complements  our  other   businesses  very  well,
particularly  XL Mid Ocean Re's  existing  property  and  specialty  reinsurance
operations.  In terms of capital,  on a combined  basis we will have the world's
largest  broker  market  reinsurance  activities.  Under the  leadership  of Ron
Bornhuetter  and Nick  Brown,  NAC Re has become one of the most  respected  and
successful   franchises  in  the   reinsurance   business  with  an  outstanding
professional staff. We expect this transaction to be not only accretive, but the
foundation upon which significant future growth in the U.S. can be built."

Nicholas  M.  Brown,  Jr.,  President  and  Chief  Executive  Officer  of NAC Re
Corporation  noted "We are very pleased with this new affiliation  with XL. They
are a highly  successful,  well-respected  and  innovative  player in the global
insurance and  reinsurance  markets.  The merger as structured will maintain the
strong NAC Re franchise and enable us to better serve our clients, providing new
and expanded  product  offerings and increasing our capacity.  This is clearly a
combination that will benefit both parties. I am looking forward to working with
Brian O'Hara and his team at XL."

Upon completion of the transaction,  Mr. Brown will serve as Chairman, President
and Chief Executive  Officer of NAC Re Corporation,  which will retain its name.
Ronald L. Bornhuetter,  current Chairman of NAC Re, along with another member of
the current NAC Re Board to be designated prior to the closing,  will be invited
to join the Board of  Directors  of XL Capital  Ltd.  Mr. Brown will also become
President and Chief Executive  Officer of XL America,  Inc. and will serve as an
Executive  Vice  President  of XL  Capital  Ltd with  responsibility  for  North
American operations.

On  a  pro-forma  basis  at  year-end  1998,  the  combined  XL  Capital/NAC  Re
organization  would have had assets of $13.3 billion,  $2.3 billion of revenues,
shareholders'   equity  of  $5.6   billion  and  a  market   capitalization   of
approximately $8 billion.

Donaldson,  Lufkin & Jenrette  Securities  Corporation and Wasserstein Perella &
Co. Inc.  acted as  financial  advisors  to XL Capital  Ltd and Morgan  Stanley,
Dean Witter & Co.  Incorporated,  CIBC Oppenheimer  Corp. and SBC Warburg Dillon
Read acted as financial advisors for NAC Re Corporation.

XL Capital Ltd,  through XL  Insurance  Ltd, XL Mid Ocean  Reinsurance  Ltd, The
Brockbank  Group plc and XL  Capital  Products  Ltd,  is a leading  provider  of
insurance and  reinsurance  coverages and financial  products  worldwide.  As of
November 30, 1998, XL Capital Ltd had assets of $10.1 billion and  shareholders'
equity of $4.8  billion.  XL Capital Ltd  changed its name from EXEL  Limited on
February 1, 1999.

NAC Re  Corporation  through  its A+ rated  subsidiaries  writes  insurance  and
reinsurance  throughout  the world.  As of December 31, 1998,  NAC Re Corp.  had
assets in  excess of $3.2  billion  and  shareholders'  equity in excess of $750
million.

Additional  information  on both XL Capital and NAC Re is  available  from their
respective web sites, `www.xl.bm' and "www.nacre.com."

This  presentation  contains forward looking  statements of management  beliefs,
estimates,  projections, and assumptions for the financial condition, results of
operations,  business and prospects of XL for NAC Re and the combined  XL/NAC Re
on a pro forma  basis,  including  statements  relating  to: (a) future  assets,
shareholders' equity,  market  capitalization and market position;  (b) the cost
savings,  synergies  and  accretion to reported and cash  earnings  that will be
realized  from the  merger;  and (c) the  restructuring  charges  expected to be
incurred in connection with the merger. These forward looking statements involve
certain risks and  uncertainties,  including those detailed from time to time in
XL's  and NAC  Re's  reports  and  filings  with  the  Securities  and  Exchange
Commission.  Factors that may cause  actual  results to differ  materially  from
those contemplated by such forward looking statements  including,  among others:
(1) expected cost savings and synergies from the merger cannot be fully realized
or realized  within the expected time frame;  (2) revenues  following the merger
are lower than expected or customer loss and business  disruption  following the
merger are greater than anticipated;  (3) competitive pressure among insurers or
reinsurers  increases  significantly;  (4) costs or difficulties  related to the
integration of the  businesses of XL and NAC Re are greater than  expected;  (5)
general economic  conditions are less favorable than expected;  (6) legislation,
tax or regulatory  changes adversely affect the businesses in which the combined
company would be engaged;  or (7) natural disasters or other catastrophic events
are more  prevalent  or  significant  than  expected,  or losses  have a greater
frequency   or  severity   than   anticipated   by  the   companies'   reserving
methodologies.
