  in each case as the holder thereof shall have elected or be deemed to have

Company Common Stock (the "Certificates") shall cease to have any rights with

          (c)  Each option granted under the Company's option plans held by
     employees and directors outstanding at the Effective Time to acquire a

     an amount in cash (the "Option Amount") equal to the Cash Consideration
                             -------------
     less the exercise price therefor. As promptly as practicable following the
     Effective Time, the Surviving Corporation shall pay to each holder of one
     or more options the applicable Option Amount (less any applicable
     withholding taxes). On the Closing Date, the Company shall deposit in a
     bank account not within the Company's control an amount of cash equal to
     the aggregate payments to be made pursuant to the prior sentence together

<PAGE>

     promptly distributed following the Effective Time to the holders of such
     options in accordance with this Section.

          (d)  Each issued and outstanding share of common stock, par value $100

     paid and nonassessable share of common stock of the Surviving Corporation.

          (e)  The calculations of the computations required by this Article II
     shall be prepared by Parent prior to the Closing Date and shall be set
     forth in a statement furnished to the Company showing in reasonable detail
     the manner of calculation.

          (f)  At the Effective Time, the stock transfer books of the Company
     shall be closed as to holders of the Company Common Stock immediately prior
     to the Effective Time and no transfer of the Company Common Stock by any
     such holder shall thereafter be made or recognized. If, after the Effective
     Time, Certificates are properly presented in accordance with this Article
     II to the Exchange Agent, such Certificates shall be canceled and exchanged
     for certificates representing the number of shares of Parent Common Stock,
     and/or a check representing the amount of cash, if any, into which the
     Company Common Stock represented thereby was converted in the Merger.

     Section 2.2.  Election Procedure. Each holder (or beneficial owner through
                   ------------------
appropriate and customary documentation and instructions) of shares of Company
Common Stock ("Shares") (other than holders of Shares to be canceled as set
               ------
forth in Section 2.1(a)) shall have the right to submit a request specifying the
number of Shares that such holder desires to have converted into shares of
Parent Common Stock in the Merger and the number of Shares that such holder
desires to have converted into the right to receive Cash Consideration in the
Merger in accordance with the following procedure:

          (a)  Subject to Section 2.3, each holder of Shares may specify in a
     request made in accordance with the provisions of this Section 2.2 (herein
     called an "Election") (i) the number of Shares owned by such holder that
                --------    -
     such holder desires to have converted into Parent Common Stock in the
     Merger (a "Stock Election") and (ii) the number of Shares owned by such
                --------------        --
     holder that such holder desires to have converted into the right to receive
     the Cash Consideration in the Merger (a "Cash Election") and (iii) the
                                              -------------        ---
     number of Shares owned by such holder as to which such holder has no
     preference as to the receipt of Cash Consideration or Parent Common Stock
     for such shares (a "Non-Election").
                         ------------

          (b)  An election form and other appropriate and customary transmittal
     materials (which shall specify that delivery shall be effected, and risk of
     loss and title to the Certificates shall pass, only upon proper delivery of
     such Certificates to the Exchange Agent) in such form as Parent and the
     Company shall mutually agree (the "Election Form") shall be mailed thirty
                                        -------------
     days prior to the anticipated Effective Time or on such other date as
     Parent and the Company shall mutually agree (the "Mailing Date") to each
                                                       ------------
     holder of record of Company Common Stock as of five business days prior to
     the Mailing Date.

                                       4
<PAGE>

          (c)  Any Election shall have been made properly only if the Exchange
     Agent shall have received, by 5:00 p.m. local time in the city in which the
     principal office of such Exchange Agent is located, on the fifth day prior
     to the anticipated Effective Time (or such other time and date as Parent
     and the Company shall mutually agree) (the "Election Deadline"), an
                                                 -----------------
     Election Form properly completed and signed and accompanied by Certificates
     for the Shares to which such Election Form relates (or customary affidavits
     and indemnification regarding the loss or destruction of such Certificate
     or Certificates or by an appropriate guarantee of delivery of such
     Certificates, as set forth in such Election Form, from a member of any
     registered national securities exchange or of the National Association of
     Securities Dealers, Inc. or a commercial bank or trust company in the
     United States provided such certificates are in fact delivered to the
     Exchange Agent by the time required in such guarantee of delivery).
     Failure to deliver Shares covered by such a guarantee of delivery within
     the time set forth on such guarantee shall be deemed to invalidate any
     otherwise properly made Election.

          (d)  Any Company stockholder may at any time prior to the Election
     Deadline revoke or change his or her Election by written notice received by
     the Exchange Agent prior to the Election Deadline accompanied by a properly
     completed and signed, revised Election Form or by withdrawal of his or her
     Certificates for Shares, or of the guarantee of delivery of such
     Certificates, previously deposited with the Exchange Agent.  In the event
     an Election Form is revoked prior to the Election Deadline, the Shares
     represented by such Election Form shall (except in the case of an All Cash
     Transaction) be promptly returned without charge to the person submitting
     the Election Form upon written request to that effect from the holder who
     submitted the Election Form.  The Exchange Agent shall have reasonable
     discretion to determine whether any election, revocation or change has been
     properly or timely made and to disregard immaterial defects in the Election
     Forms, and any good faith decisions of the Exchange Agent regarding such
     matters shall be binding and conclusive.  The Exchange Agent shall be under
     no obligation to notify any person of any defect in an Election Form.  All
     Elections shall be revoked automatically in the event of an All Cash
     Transaction or if the Exchange Agent is notified in writing by Parent or
     the Company that this Agreement has been terminated.

          (e)  Within fifteen calendar days after the Election Deadline, unless
     the Effective Time has not yet occurred, in which case as soon thereafter
     as practicable, Parent shall cause the Exchange Agent to effect the
     allocation among the holders of Company Common Stock of rights to receive
     Parent Common Stock or Cash Consideration in the Merger in accordance with
     Section 2.3.

     Section 2.3.  Issuance of Parent Common Stock and Payment of Cash
                   ---------------------------------------------------
Consideration; Proration.  The manner in which each Share (other than Shares to
- ------------------------
be canceled as set forth in Section 2.1(a) and Dissenting Shares) shall be
converted into Parent Common Stock or the right to receive the Cash
Consideration at the Effective Time shall be as set forth in this Section 2.3.
All references to "outstanding" Shares in this Section 2.3 shall mean (i) all
                                                                       -
Shares outstanding immediately prior to the Effective Time, less (ii) Shares to
                                                                  --
be cancelled as set forth in Section 2.1(a).

<PAGE>

          (a)  As is more fully set forth below, the number of Shares to be
     converted into the right to receive the Cash Consideration pursuant to the
     Merger shall be equal to 50% of all outstanding Shares less the sum of (i)
                                                                             -
     the number of Dissenting Shares, if any, which are not to be treated as
     Non-Electing Shares pursuant to Section 2.4 and (ii) the number of Shares
                                                      --
     to be exchanged for cash in lieu of fractional shares pursuant to Section
     2.5(e) (the "Cash Election Number").  The number of Shares to be converted
                  --------------------
     into the right to receive Parent Common Stock in the Merger shall be equal
     to 50% of all outstanding Shares (the "Stock Election Number").
                                            ---------------------

          (b)  If the aggregate number of Shares covered by Cash Elections (the
     "Cash Election Shares") exceeds the Cash Election Number, all Shares
      --------------------
     covered by Stock Elections (the "Stock Election Shares") and all Shares
                                      ---------------------
     covered by Non-Elections (the "Non-Electing Shares") shall be converted
                                    -------------------
     into the right to receive Parent Common Stock, and the Cash Election Shares
     shall be converted into the right to receive Parent Common Stock and cash
     in the following manner:

          each Cash Election Share shall be converted into the right to receive
          (i) an amount in cash, without interest, equal to the product of (x)
           -                                                                -
          the Cash Consideration and (y) a fraction (the "Cash Fraction"), the
                                      -                   -------------
          numerator of which shall be the Cash Election Number and the
          denominator of which shall be the total number of Cash Election
          Shares, and (ii) a number of shares of Parent Common Stock equal to
                       --
          the product of (x) the Common Stock Consideration and (y) a fraction
                          -                                      -
          equal to one minus the Cash Fraction.

          (c)  If the aggregate number of Stock Election Shares exceeds the
     Stock Election Number, all Cash Election Shares and all Non-Electing Shares
     shall be converted into the right to receive cash, and all Stock Election
     Shares shall be converted into the right to receive Parent Common Stock and
     cash in the following manner:

          each Stock Election Share shall be converted into the right to receive
          (i) a number of shares of Parent Common Stock equal to the product of
           -
          (x) the Common Stock Consideration and (y) a fraction (the "Stock
           -                                      -                   -----
          Fraction"), the numerator of which shall be the Stock Election Number
          --------
          and the denominator of which shall be the total number of Stock
          Election Shares, and (ii) an amount in cash, without interest, equal
                                --
          to the product of (x) the Cash Consideration and (y) a fraction equal
                             -                              -
          to one minus the Stock Fraction.

          (d)  For the purposes of this Section 2.3, outstanding Shares as to
     which an Election is not in effect at the Election Deadline shall be
     considered Non-Electing Shares.  If Parent and the Company shall determine
     that any Election is not properly made with respect to any Shares, such
     Election shall be deemed to be not in effect, and the Shares covered by
     such Election shall, for purposes hereof, be deemed to be Non-Electing
     Shares.

                                       6
<PAGE>

          (e)  Notwithstanding any provision of this Agreement to the contrary,
     all outstanding Shares shall be converted in the Merger into Cash
     Consideration (i) in the event that the Average Parent Price is less than
                    -
     $65.00 per Share, and Parent elects to pay the Cash Consideration for all
     outstanding Shares by delivering written notice to the Company of such
     election within two (2) business days following determination of the
     Average Parent Price; (ii) in the event that the Average Parent Price
                            --
     exceeds $75.00 per Share; and (iii) in the event that the closing price of
                                    ---
     Parent Common Stock on the NYSE on the Trading Day immediately preceding
     the Closing Date scheduled in accordance with Section 1.2 (without taking
     account the last sentence of this subsection) is less than the Average
     Parent Price, and as a result, the opinion required by either Section
     6.2(b) or Section 6.3(b) is not delivered (in any of the events described
     under this subsection (e), the Merger shall be an "All Cash Transaction").
                                                        --------------------
     In the event that the Merger is an All Cash Transaction because of clause
     (iii) above, the Closing Date shall be extended by two business days, but
     the Average Parent Price shall not be recalculated as a result of such
     extension.

          (f)  Notwithstanding any provision of this Agreement to the contrary,
     in the event that the Merger is an All Cash Transaction, then the
     transaction will be treated as an acquisition by Parent of all of the stock
     of the Company, and the structure of the Merger will change, such that the
     Merger Sub will merge with and into the Company, the separate existence of
     Merger Sub will cease and the Company will continue as the Surviving
     Corporation and the Certificate of Incorporation and By-laws of the Company
     will become the Certificate of Incorporation and By-laws of the Surviving
     Corporation.

     Section 2.4.  Appraisal Rights.  Notwithstanding any provision of this
                   ----------------
Agreement to the contrary, each outstanding share of Company Common Stock the
holder of which has not voted in favor of the Merger, has perfected such
holder's right to an appraisal of such holder's shares in accordance with the
applicable provisions of the DGCL and has not effectively withdrawn or lost such
right to appraisal (a "Dissenting Share") shall not be converted into or
                       ----------------
represent a right to receive the Merger Consideration, but the holder thereof
shall be entitled only to such rights as are granted by the applicable
provisions of the DGCL; provided, however, that any Dissenting Share held by a
                        --------  -------
person at the Effective Time who shall, after the Effective Time, withdraw the
demand for appraisal within 60 days after the Effective Time or shall lose the
right of appraisal, in either case pursuant to the DGCL, shall be treated as a
Non-Electing Share for purposes of Section 2.3.  The Company shall give Parent
(i) prompt notice of any written demands for appraisal, withdrawals of demands
 -
for appraisal and any other instruments served pursuant to the applicable
provisions of the DGCL relating to the appraisal process received by the Company
and (ii) the opportunity to direct all negotiations and proceedings with respect
     --
to demands for appraisal under the DGCL.  The Company will not voluntarily make
any payment with respect to any demands for appraisal and will not, except with
the prior written consent of Parent, settle or offer to settle any such demands.
Notwithstanding anything to the contrary in this Section 2.4, if (A) the Merger
                                                                  -
is rescinded or abandoned or (B) the stockholders of the Company revoke the
                              -
authority to effect the Merger, the right of any stockholder of the Company to
be paid the fair value of such stockholder's Dissenting Shares pursuant to the
DGCL shall cease.

     Section 2.5.  Exchange of Certificates.  (a)  Exchange Agent.  As of the
                   ------------------------        --------------
Effective Time, Parent shall enter into an agreement with First Union National
Bank or such other bank or trust

                                       7
<PAGE>

company as may be designated by Parent and as shall be reasonably satisfactory
to the Company (the "Exchange Agent"), which shall provide that Parent shall
                     --------------
deposit with the Exchange Agent as promptly as practicable following the
Effective Time, for the benefit of the holders of shares of Company Common
Stock, for exchange in accordance with this Article II, through the Exchange
Agent, the aggregate Merger Consideration plus additional cash for dividends and
fractional shares. The aggregate Merger Consideration (together with any
dividends or distributions with respect thereto with a record date after the
Effective Time) and any cash payable in lieu of any fractional shares of Parent
Common Stock are hereinafter referred to as the "Exchange Fund."
                                                 -------------

     (b)  Exchange Procedures.  Upon surrender of a Certificate for cancellation
          -------------------
to the Exchange Agent, the holder of such Certificate shall be entitled to
receive in exchange therefor the applicable Merger Consideration, certain
dividends or other distributions in accordance with Section 2.5(c) and cash in
lieu of any fractional share in accordance with Section 2.5(e), and the
Certificate so surrendered shall forthwith be cancelled.  In the event of a
transfer of ownership of Company Common Stock which is not registered in the
transfer records of the Company, the applicable Merger Consideration may be
issued to a person other than the person in whose name the Certificate so
surrendered is registered if such Certificate shall be properly endorsed or
otherwise be in proper form for transfer and the person requesting such issuance
shall pay any transfer or other non-income taxes required by reason of the
issuance of shares of Parent Common Stock to a person other than the registered
holder of such Certificate or establish to the satisfaction of Parent that any
such tax has been paid or is not applicable.  Parent or the Exchange Agent shall
be entitled to deduct and withhold from the consideration otherwise payable
pursuant to this Agreement to any holder of Company Common Stock such amounts as
Parent or the Exchange Agent are required to withhold or deduct under the Code
or any provision of state, local or foreign tax law with respect to the making
of such payment.  To the extent that amounts are so withheld by Parent or the
Exchange Agent, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the Company Common Stock in
respect of whom such deduction and withholding were made by Parent or the
Exchange Agent.  Until surrendered as contemplated by this Section 2.5, each
Certificate shall be deemed at any time after the Effective Time to represent
only the right to receive upon such surrender the applicable Merger
Consideration, certain dividends or other distributions in accordance with
Section 2.5(c) and cash in lieu of any fractional share in accordance with
Section 2.5(e).  No interest will be paid or will accrue on any cash payable to
holders of Certificates pursuant to the provisions of this Article II.

     (c)  Distributions with Respect to Unexchanged Shares.  No dividends or
          ------------------------------------------------
other distributions with respect to Parent Common Stock with a record date after
the Effective Time shall be paid to the holder of any unsurrendered Certificate
with respect to the shares of Parent Common Stock represented thereby, and no
cash payment in lieu of fractional shares shall be paid to any such holder
pursuant to Section 2.5(e), and all such dividends, other distributions and cash
in lieu of fractional shares of Parent Common Stock shall be paid by Parent to
the Exchange Agent and shall be included in the Exchange Fund, in each case
until the surrender of such Certificate in accordance with this Article II.
Subject to the effect of applicable escheat or similar laws and laws with
respect to the withholding of Taxes, following surrender of any such Certificate
there shall be paid to the holder of shares of Parent Common Stock issued in
exchange therefor, without interest, (i) at the time of such surrender, the
                                      -
amount of dividends or

                                       8
<PAGE>

other distributions with a record date after the Effective Time theretofore paid
with respect to such whole shares of Parent Common Stock and the amount of any
cash payable in lieu of a fractional share of Parent Common Stock to which such
holder is entitled pursuant to Section 2.2(e) and (ii) 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 with a payment date
subsequent to such surrender payable with respect to such whole shares of Parent
Common Stock. Parent shall make available to the Exchange Agent cash for these
purposes.

     (d)   No Further Ownership Rights in Company Common Stock.  The payment of
           ---------------------------------------------------
the applicable Merger Consideration upon the surrender for exchange of
Certificates in accordance with the terms of this Article II (including
distributions and dividends paid pursuant to Section 2.5(c) and any cash paid in
lieu of fractional shares pursuant to Section 2.5(e)) shall be deemed payment in
full satisfaction of all rights pertaining to the shares of Company Common Stock
theretofore represented by such Certificates, subject, however, to the Surviving
Corporation's obligation to pay any dividends or make any other distributions
with a record date prior to the Effective Time which may have been authorized or
made by the Company on such shares of Company Common Stock which remain unpaid
at the Effective Time.

     (e)   No Fractional Shares.  (i)  No certificates or scrip representing
           --------------------
fractional shares of Parent Common Stock shall be issued upon the surrender for
exchange of Certificates, no dividend or distribution of Parent shall relate to
such fractional share interests and such fractional share interests will not
entitle the owner thereof to vote or to any rights of a stockholder of Parent.

     (ii)  As promptly as practicable following the Effective Time, the
Surviving Company shall pay to each holder of Company Common Stock an amount in
cash, if any, equal to the product obtained by multiplying the fractional
interest in a share of Parent Common Stock to which such holder (after taking
into account all shares of Company Common Stock held at the Effective Time by
such holder) would otherwise be entitled by the Average Parent Price.

     (iii) As soon as practicable after the determination of the amount of cash,
if any, to be paid to holders of Company Common Stock with respect to any
fractional share interests, the Exchange Agent will make available such amounts
to such holders of Company Common Stock subject to the terms of Section 2.5(c).

     (f)   Termination of Exchange Fund.  Any portion of the Exchange Fund which
           ----------------------------
remains undistributed to the holders of the Certificates for six months after
the Effective Time shall be delivered to Parent upon demand, and any holders of
the Certificates who have not theretofore complied with this Article II shall
thereafter look only to Parent for payment of their claim for Merger
Consideration, any cash in lieu of fractional shares of Parent Common Stock and
any dividends or distributions with respect to Parent Common Stock.

     (g)   No Liability.  None of the Company, Parent, Merger Sub, the Surviving
           ------------
Corporation or the Exchange Agent shall be liable to any person in respect of
any shares of Parent Common Stock (or dividends or distributions with respect
thereto) or cash from the Exchange Fund in each case delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law.

                                       9
<PAGE>

     (h)  Investment of Exchange Fund.  The Exchange Agent shall invest all cash
          ---------------------------
included in the Exchange Fund, as directed by Parent.  Any interest and other
income resulting from such investments shall be paid to Parent.

     (i)  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 the
Surviving Corporation, the posting by such person of a bond in such reasonable
amount as the Surviving Corporation may direct as indemnity against any claim
that may be made against it with respect to such Certificate, the Exchange Agent
will issue in exchange for such lost, stolen or destroyed Certificate the Merger
Consideration and, if applicable, any cash in lieu of fractional shares, and
unpaid dividends and distributions on shares of Parent Common Stock deliverable
in respect thereof, pursuant to this Agreement.

     (j)  Adjustments. If at any time during the period between the date of this
          -----------
Agreement and the Effective Time any change in the outstanding shares of capital
stock of the Company or Parent shall occur as a result of any reclassification,
recapitalization, stock split (including a reverse stock split) or combination,
exchange or readjustment of shares or any stock dividend or stock distribution
with a record date during such period, the Merger Consideration shall be
equitably adjusted.

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     Except as specifically set forth, by reference to a particular section of
this Agreement, on the Disclosure Schedule delivered by the Company to Parent
prior to the execution of this Agreement (the "Company Disclosure Schedule"),
                                               ---------------------------
the Company represents and warrants to Parent and Merger Sub as follows:

     Section 3.1.  Organization, Qualification, Etc.  (a)  The Company is a

and is duly qualified to do business and is in good standing in each
jurisdiction in which the ownership of its properties or the conduct of its

aggregate, have a Material Adverse Effect (as hereinafter defined) on the
Company.  As used in this Agreement, any reference to any state of facts, event,
change or effect having a "Material Adverse Effect" on or with respect to the
                           -----------------------

                                              ---
     December 31, 1996, 1997 and 1998;

          (ii)  each definitive proxy statement filed by the Company with the
     SEC since December 31, 1996;

          (iii) each final prospectus filed by the Company with the SEC since
     December 31, 1996, except any final prospectus on Form S-8; and

          (iv)  all Current Reports on Form 8-K and Quarterly Reports on Form
     10-Q filed by the Company with the SEC since December 31, 1998.

     As of their respective dates, such reports, proxy statements and
prospectuses (collectively, the "Company SEC Reports") (i) complied as to form
                                 -------------------    -
in all material respects with the applicable requirements of the Securities Act,
the Exchange Act and the rules and regulations promulgated thereunder and (ii)
                                                                           --
did not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading.  The audited consolidated financial statements and unaudited
consolidated interim financial statements included in the Company SEC Reports
(including any related notes and schedules) fairly present the financial
position of the Company and its consolidated Subsidiaries as of the dates
thereof and the results of operations and cash flows for the periods or as of
the dates then ended (subject, in the case of the unaudited interim financial
statements, to normal recurring year-end adjustments), in each case in
accordance with generally accepted accounting principles in the United States
("GAAP") consistently applied during the periods involved (except as otherwise
  ----
disclosed in the notes thereto).  The Company has also previously furnished to
Parent all audit reports and letters to management regarding accounting controls
received since January 1, 1997 from the auditors of the Company and its
Subsidiaries and all responses thereto from the Company and its Subsidiaries.
Since December 31, 1996, the Company has timely filed all reports, registration
statements and other filings required to be filed by it with the SEC under the
rules and regulations of the SEC.  None of the Company's Subsidiaries is
required to file any forms, reports or other documents with the SEC.

     (b)  The Company has made available to Parent true and complete copies of
the annual and quarterly statements of each of the Company Insurance
Subsidiaries as filed with the applicable insurance regulatory authorities for
the years ended December 31, 1996, 1997 and 1998 and the quarterly periods ended
March 31, 1999 and June 30, 1999, including all exhibits, interrogatories,
notes, schedules and any actuarial opinions, affirmations or certifications or
other supporting documents filed in connection therewith (collectively, the
"Company SAP Statements").  The Company SAP Statements were prepared in
 ----------------------
conformity with statutory accounting practices prescribed or permitted by the
applicable insurance regulatory authority consistently applied for the periods
covered thereby and present fairly the statutory financial position of such
Company Insurance Subsidiaries as at the respective dates thereof and the

results of operations of such Subsidiaries for the respective periods then
ended. Section 3.4(b) of the Company Disclosure Schedules sets forth the
permitted exceptions from statutory accounting practices received from any
regulatory authorities. The Company SAP Statements complied in all material
respects with all applicable laws, rules and regulations when filed, and, to the
Knowledge of the Company, no material deficiency has been asserted with respect
to any Company SAP Statements by the applicable insurance regulatory body or any
other governmental agency or body. The annual statutory balance sheets and
income statements included in the Company SAP Statements have been audited by
KPMG Peat Marwick LLP, and the Company has made available to Parent true and
complete copies of all audit opinions related thereto. The Company has made
available to Parent true and complete copies of all examination reports of
insurance departments and any insurance regulatory agencies since January 1,
1996 relating to the Company Insurance Subsidiaries. To the Knowledge of the
Company, the amounts shown in the Company SAP Statements as reserves and
liabilities for past and future insurance policy benefits, losses, claims and
expenses under insurance policies as of the end of each such reporting period
were fairly stated in accordance with generally accepted actuarial principles
consistently applied, were based on actuarial assumptions which were in
accordance with those called for in the policy provisions and met the
requirements of the insurance laws of the applicable insurance authority, with
such exceptions as would not, individually or in the aggregate, reasonably be
likely to have a Material Adverse Effect. Such amounts shown on the Company SAP
Statements filed after the date hereof and on or prior to the Closing Date will
be so computed and based and will meet all such requirements.

Company).  All Taxes due and owing by the Company, any Subsidiary of the Company
or any Company Affiliated Group have been timely paid, or adequately reserved

in the aggregate, have a Material Adverse Effect on the Company.  All

of the Company Disclosure Schedule, the Company and each of its Subsidiaries
have complied in all material respects with all rules and regulations relating
to tax information reporting and the payment and withholding of Taxes, except to
the extent any such failure to comply would not, individually or in the

has not asserted in writing that any such policy fails to so qualify.  The
assets of any separate account are adequately diversified within the meaning of
Section 817(h) of the Code, and each Company Insurance Subsidiary is treated for

Company is in default (or with the giving of notice or lapse of time or both,
would be in default) under any license to use such Intellectual Property, such
Intellectual Property is not being infringed by any third party, and neither the
Company nor any Subsidiary of the Company is infringing any Intellectual

readiness, with respect to the year 2000 issue, of its vendors and its

                   --------------------------------
furnished or made available to the Company true and complete copies of:

           the years ended December 31, 1996 through 1998;

     (ii)  each definitive proxy statement filed by Parent with the SEC since

     (iv)  all Current Reports on Form 8-K filed by Parent with the SEC since
           December 31, 1998.

     As of their respective dates, such reports, proxy statements and
prospectuses (collectively, the "Parent SEC Reports") (i) complied as to form in
                                 ------------------    -
all material respects with the applicable requirements of the Securities Act,
the Exchange Act and the rules and regulations promulgated thereunder and (ii)
                                                                           --
did not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading.  The audited consolidated financial statements and unaudited
consolidated interim financial statements included in the Parent SEC Reports
(including any related notes and schedules) fairly present the financial
position of the Parent and its consolidated Subsidiaries as of the dates thereof
and the

                                       26
<PAGE>

results of operations and cash flows for the periods or as of the dates then
ended (subject, in the case of the unaudited interim financial statements, to
normal recurring year-end adjustments), in each case in accordance with GAAP
consistently applied during the periods involved (except as otherwise disclosed
in the notes thereto). Parent has also previously furnished to the Company all
audit reports and letters to management regarding accounting controls received
since January 1, 1997 from the auditors of Parent and its Subsidiaries and all
responses thereto from Parent and its Subsidiaries. Since December 31, 1996,
Parent has timely filed all reports, registration statements and other filings
required to be filed by it with the SEC under the rules and regulations of the
SEC.

     (b)  Parent has made available to the Company true and complete copies of
the annual and quarterly statements of each of Parent's Subsidiaries listed in
Section 4.4(b) of the Parent Disclosure Schedule ("Parent Insurance
                                                   ----------------
Subsidiaries") as filed with the applicable insurance regulatory authorities for
- ------------
the years ended December 31, 1996, 1997 and 1998 and the quarterly periods ended
March 31, 1999 and June 30, 1999, including all exhibits, interrogatories,
notes, schedules and any actuarial opinions, affirmations or certifications or
other supporting documents filed in connection therewith (collectively, the
"Parent SAP Statements").  The Parent SAP Statements were prepared in conformity
 ---------------------
with statutory accounting practices prescribed or permitted by the applicable
insurance regulatory authority consistently applied for the periods covered
thereby and present fairly the statutory financial position of such Parent
Insurance Subsidiaries as at the respective dates thereof and the results of
operations of such Subsidiaries for the respective periods then ended.  The
Parent SAP Statements complied in all material respects with all applicable
laws, rules and regulations when filed, and, to the Knowledge of Parent, no
material deficiency has been asserted with respect to any Parent SAP Statements
by the applicable insurance regulatory body or any other governmental agency or
body.  The annual statutory balance sheets and income statements included in the
1996 Parent SAP Statements have been audited by McGladrey & Pullen L.L.P. and
the annual statutory balance sheets and income statements included in the 1997
and 1998 Parent SAP Statements have been audited by Ernst & Young L.L.P., and
Parent has made available to the Company true and complete copies of all audit
opinions related thereto.  Parent has made available to the Company true and
complete copies of all examination reports of insurance departments and any
insurance regulatory agencies since January 1, 1996 relating to the Parent
Insurance Subsidiaries.  To the Knowledge of Parent, the amounts shown in the
Parent SAP Statements as reserves and liabilities for past and future insurance
policy benefits, losses, claims and expenses under insurance policies as of the
end of each such reporting period were fairly stated in accordance with
generally accepted actuarial principles consistently applied, were based on
actuarial assumptions which were in accordance with those called for in the
policy provisions and met the requirements of the insurance laws of the
applicable insurance authority, with such exceptions as would not, individually
or in the aggregate, reasonably be likely to have a Material Adverse Effect.
Such amounts shown on the Parent SAP Statements filed after the date hereof and
on or prior to the Closing Date will be so computed and based and will meet all
such requirements.

     Section 5.2.  Investigation.  Each of the Company and Parent shall afford
                   -------------
to one another and to one another's officers, employees, accountants, counsel
and other authorized representatives full and complete access during normal
business hours upon reasonable notice, throughout the period prior to the
earlier of the Effective Time or the Termination Date, to its and its
Subsidiaries' properties, contracts, commitments, books and records and any
report, schedule or other document filed or received by it pursuant to the
requirements of federal or state securities laws and shall use its reasonable
best efforts to cause its respective representatives to furnish promptly to
Parent such additional financial and operating data and other information as to
its and its Subsidiaries' businesses and properties as Parent or its duly
authorized representatives may from time to time reasonably request. The parties
hereby agree that each of them will treat any such information in accordance
with the Confidentiality Agreement, dated as of June 2, 1999, between the
Company and Parent (the "Confidentiality Agreement"). Notwithstanding any
                         -------------------------
provision of this Agreement to the contrary, no party shall be obligated to make
any disclosure in violation of applicable laws or regulations, including any
such laws or regulations pertaining to the treatment of classified information.

     Section 5.3.  Proxy Material; Registration Statement.  (a)  The Company and
                   --------------------------------------
Parent shall together, or pursuant to an allocation of responsibility to be
agreed upon between them:

          (i)  prepare and file with the SEC as soon as is reasonably
     practicable the Proxy Statement and a registration statement on Form S-4
     under the Securities Act with respect to the Parent Common Stock issuable
     in the Merger (the "Registration Statement"), and shall use their
                         ----------------------
     reasonable best efforts to have the Proxy Statement cleared by the SEC
     under the Exchange Act and the Registration Statement declared effective by
     the SEC under the Securities Act as promptly as practicable. No filing of,
     or amendment or supplement to, the Registration Statement or the Proxy
     Statement will be made by Parent or the Company without providing the other
     a reasonable opportunity to review and comment thereon. The Company will
     advise Parent, and Parent will advise the Company, promptly after it
     receives notice thereof, of any request by the SEC for amendment of the
     Proxy Statement or the Registration Statement or comments thereof or
     requests by the SEC for additional information. The Company and Parent
     shall each provide the other with copies of any communication received from
     or sent to the SEC in connection with the Proxy Statement or the
     Registration Statement and with a reasonable opportunity to review all
     responses to SEC comments or other requests prior to their being sent to
     the SEC. If at any time prior to the Effective Time any information
     relating to Parent or the Company, or any of their respective affiliates,
     officers or directors, should be discovered by Parent or the Company which
     should be set forth in an amendment or supplement to the Registration
     Statement or the Proxy Statement, so that any such documents would not
     include any misstatement of a material fact or omit to state any material
     fact required to be stated therein or necessary to make the statements
     therein, in light of the circumstances under which they were made, not
     misleading, the

                                       33
<PAGE>

     party which discovered such information shall promptly notify the other
     party hereto and an appropriate amendment or supplement describing such
     information shall be promptly filed with the SEC and, to the extent
     required by law, disseminated to the stockholders of the Company;

          (ii)   as soon as is reasonably practicable take all such action as
     may be required under state blue sky or securities laws in connection with
     the transactions contemplated by this Agreement;

          (iii)  promptly prepare and file with the NYSE and such other stock
     exchanges as shall be agreed upon listing applications covering the shares
     of Parent Common Stock issuable in the Merger and use their reasonable best
     efforts to obtain, prior to the Effective Time, approval for the listing of
     such Parent Common Stock, subject only to official notice of issuance;

          (iv)   cooperate with one another in order to lift any injunctions or
     remove any other impediment to the consummation of the transactions
     contemplated herein; and

          (v)    cooperate with one another in obtaining opinions of Kutak Rock,
     counsel to the Company, and King & Spalding, counsel to Parent, dated as of
     the Effective Time, to the effect that the Merger will qualify as a
     reorganization within the meaning of Section 368(a) of the Code. In
     connection therewith, each of the Company, Parent and Merger Sub shall
     deliver to Kutak Rock and King & Spalding, respectively, representation
     letters in form and substance reasonably satisfactory to such tax counsel.

     (b)  Subject to the limitations contained in Section 5.2, the Company and
Parent shall each furnish to one another and to one another's counsel all such
information as may be required in order to effect the foregoing actions.

     (c)  The Company and Parent shall cause the Proxy Statement to be mailed to
the Company's stockholders as promptly as practicable after the Registration
Statement is declared effective under the Securities Act.

     (d)  The Company shall duly call, give notice of, convene and hold a
meeting of its stockholders (the "Company Meeting") for the purpose of obtaining
                                  ---------------
the Company Stockholder Approval and shall, through its Board of Directors,
subject to Section 5.9(b), recommend to its stockholders the adoption of this
Agreement, the Merger and the other transactions contemplated hereby. Without
limiting the generality of the foregoing but subject to its rights to terminate
this Agreement pursuant to Section 7.1, the Company agrees that its obligations
pursuant to the first sentence of this Section 5.3(d) shall not be affected by
the commencement, public proposal, public disclosure or communication to the
Company of any Takeover Proposal (as defined in Section 5.9).

     Section 5.4.  Affiliate Agreements.  The Company shall, prior to the
                   --------------------
Effective Time, deliver to Parent a list (reasonably satisfactory to counsel for
Parent) setting forth the names and addresses of all persons who are, at the
time of the Company Meeting, in the Company's reasonable judgment, "affiliates"
of the Company for purposes of Rule 145 under the Securities Act. The Company
shall furnish such information and documents as Parent may reasonably

                                       34
<PAGE>

request for the purpose of reviewing such list. The Company shall use its
reasonable best efforts to cause each person who is identified as an "affiliate"
in the list furnished pursuant to this Section 5.4 to execute a written
agreement on or prior to the mailing of the Proxy Statement, substantially in
the form of Exhibit A hereto.

     Section 5.5.  Employee Incentive and Benefit Plans.  Simultaneously with
                   ------------------------------------
the Merger, Parent agrees to take, and cause the Company to take, the actions
described in Exhibit B hereto with respect to employee benefit plans.

     Section 5.6.  Filings; Other Action.  (a)  Subject to the terms and
                   ---------------------
conditions herein provided, the Company and Parent shall (i) promptly make their
                                                          -
respective filings and thereafter make any other required submissions under the
HSR Act, (ii) promptly make their respective filings and thereafter make any
          --
other required submissions with applicable insurance regulatory authorities,
including insurance regulatory authorities in the State of Nebraska and the
Commonwealth of Pennsylvania, (iii) use their reasonable best efforts to
                               ---
cooperate with one another in (x) determining whether any filings are required
                               -
to be made with, or consents, permits, authorizations or approvals are required
to be obtained from, any third party or other governmental or regulatory bodies
or authorities of federal, state, local and foreign jurisdictions in connection
with the execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby and (y) timely making all such filings and
                                      -
timely seeking all such consents, permits, authorizations or approvals, (iv) use
                                                                         --
their reasonable best efforts to take, or cause to be taken, all other actions
and do, or cause to be done, all other things necessary, proper or advisable to
consummate and make effective the transactions contemplated hereby, including,
without limitation, taking all such further action as reasonably may be
necessary to resolve such objections, if any, as the Federal Trade Commission,
the Antitrust Division of the Department of Justice, state antitrust enforcement
authorities or competition authorities of any other nation or other jurisdiction
or any other person may assert under relevant antitrust or competition laws with
respect to the transactions contemplated hereby.

     (b)  In furtherance and not in limitation of the covenants of the parties
contained in this Section 5.6, if any administrative or judicial action or
proceeding, including any proceeding by a private party, is instituted (or
threatened to be instituted) challenging any transaction contemplated by this
Agreement as violative of any Regulatory Law (as defined below), each of the
Company and Parent shall cooperate in all respects with each other and use its
respective reasonable best efforts to contest and resist any such action or
proceeding and to have vacated, lifted, reversed or overturned any decree,
judgment, injunction or other order, whether temporary, preliminary or
permanent, that is in effect and that prohibits, prevents or restricts
consummation of the transactions contemplated by this Agreement. Notwithstanding
the foregoing or any other provision of this Agreement, nothing in this Section
5.6 shall limit a party's right to terminate this Agreement pursuant to Section
7.1(b) or 7.1(c) so long as such party has up to then complied in all respects
with its obligations under this Section 5.6.

     (c)  If any objections are asserted with respect to the transactions
contemplated hereby under any Regulatory Law or if any suit is instituted by any
governmental body or authority or any private party challenging any of the
transactions contemplated hereby as violative of any Regulatory Law, each of the
Company and Parent shall use its reasonable best efforts to resolve any such
objections or challenge as such governmental body or authority or private party
may

                                       35
<PAGE>

have to such transactions under such Regulatory Law so as to permit consummation
of the transactions contemplated hereby. For purposes of this Agreement,
"Regulatory Law" means applicable state insurance laws and regulations, the
 --------------
Sherman Act, as amended, the Clayton Act, as amended, the HSR Act, the Federal
Trade Commission Act, as amended, and all other federal, state or foreign, if
any, statutes, rules, regulations, orders, decrees, administrative and judicial
doctrines and other laws that are designed or intended to prohibit, restrict or
regulate actions having the purpose or effect of monopolization or restraint of
trade or lessening competition, whether in the insurance industry or otherwise,
through merger or acquisition.

     Section 5.7.  Further Assurances.  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 of the Company and Parent shall take all
such necessary action.

     Section 5.8.  Takeover Statute.  If any "fair price," "moratorium,"
                   ----------------
"control share acquisition" or other form of antitakeover statute or regulation
shall become applicable to the transactions contemplated hereby, each of the
Company and Parent and the members of their respective Boards of Directors shall
grant such approvals and take such actions as are reasonably necessary so that
the transactions contemplated hereby may be consummated as promptly as
practicable on the terms contemplated hereby and otherwise act to eliminate or
minimize the effects of such statute or regulation on the transactions
contemplated hereby.

     Section 5.9.  No Solicitation.  (a)  The Company represents and warrants
                   ---------------
that it has terminated any discussions or negotiations with any party (other
than Parent) concerning any Takeover Proposal prior to the date hereof. From and
after the date hereof, the Company will not, and shall use its reasonable best
efforts not to permit, any of its officers, directors, employees, attorneys,
financial advisors, agents or other representatives or those of any of its
Subsidiaries (collectively, "Company Representatives") to, directly or
                             -----------------------
indirectly, solicit, initiate or knowingly encourage (including by way of
furnishing information) any Takeover Proposal from any persons or engage in or
continue discussions or negotiations relating thereto, or take any other action
to facilitate any inquiries or the making of any proposal that constitutes, or
may reasonably be expected to lead to, any Takeover Proposal, except that, so
long as the Company is in compliance with its obligations under this Section
5.9, the Company may, in response to a Takeover Proposal that the Board of
Directors determines is reasonably likely to constitute a Superior Proposal that
was not solicited by the Company or any of its Company Representatives, and that
did not otherwise result from a breach or a deemed breach of this Section, and
subject to providing prior written notice of its decision to take such action to
Parent, (x) furnish information with respect to the Company to any person making
         -
such a Takeover Proposal pursuant to a customary confidentiality agreement with
terms substantially similar to those of the agreement to which Parent is a party
with the Company, and (y) participate in discussions or negotiations regarding
                       -
such Takeover Proposal. Without limiting the foregoing, it is agreed that any
action that is in violation of the restrictions set forth in the preceding
sentence by any executive officer of the Company or any Subsidiary of the
Company, whether or not such person is purporting to act on behalf of the
Company or any of its Subsidiaries or otherwise, shall be deemed to be a breach
of this Section 5.9 by the Company. The Company will advise Parent orally
(within one business day) and in writing (as promptly as practicable) of the
receipt of any Takeover Proposal or inquiry or request for information with
respect to or which could reasonably be expected to lead to any Takeover
Proposal, including the material terms and conditions thereof (and any

                                       36
<PAGE>

change in the material terms and conditions thereof) and the identity of the
person making such Takeover Proposal, and will promptly (but in no case later
than 36 hours) notify Parent of any determination by the Company's Board of
Directors that a Superior Proposal has been made. As used in this Agreement, (i)
                                                                              -
"Takeover Proposal" shall mean any inquiry, proposal or offer from any person
 -----------------
relating to any direct or indirect acquisition or purchase of business that
constitutes 15% or more of the net revenues, net income or the assets of the
Company and its Subsidiaries taken as a whole, or 15% or more of any class of
equity securities of the Company or any of its Subsidiaries (other than PFG,
Inc. and its Subsidiaries), any tender offer or exchange offer that if
consummated would result in any person beneficially owning 15% or more of any
class of equity securities of the Company or any of its Subsidiaries (other than
PFG, Inc. and its Subsidiaries), or any merger, consolidation, business
combination, recapitalization, liquidation, dissolution or similar transaction
involving the Company or any of its Subsidiaries, other than the transactions
contemplated by this Agreement, and (ii) "Superior Proposal" shall mean any
                                     --   -----------------
proposal made by a third party to acquire, directly or indirectly, including
pursuant to a tender offer, exchange offer, merger, consolidation, business
combination, recapitalization, liquidation, dissolution or similar transaction,
for consideration consisting of cash and/or securities, more than 50% of the
combined voting power of the shares of the Company Common Stock then outstanding
or at least 50% of the assets of the Company and its Subsidiaries, taken
together, and (x) the proposal is otherwise on terms which the Board of
               -
Directors determines in its good faith judgment (based on the advice of a
financial advisor of nationally recognized reputation and such other matters as
the Board of Directors deems relevant) to be more favorable to the Company's
stockholders than the Merger and for which financing, to the extent required, is
then committed or which in the good faith judgment of the Board of Directors is
reasonably capable of being obtained by a third party and (y) the Board of
                                                           -
Directors, after considering such matters as the Board of Directors deems
relevant (including the advice of outside counsel), determines in good faith
that failing to furnish information to the third party, participate in
discussions or negotiations with respect to the Superior Proposal or withdraw,
or modify its recommendation or recommend a Superior Proposal, as applicable, or
terminate this Agreement, is reasonably likely to result in a breach by the
Board of Directors of the Company of its fiduciary duties to the Company and its
stockholders under applicable law.

     (b)  The Board of Directors of the Company shall not (i) withdraw or
                                                           -
modify, or propose to withdraw or modify, in a manner adverse to Parent or
Merger Sub, the approval or recommendation by such Board of Directors of this
Agreement or the Merger or (ii) approve or recommend, or propose to approve or
                            --
recommend, any Takeover Proposal, unless, in each case, the Company receives an
unsolicited Takeover Proposal that is a Superior Proposal. The Board of
Directors may not enter into an agreement with respect to a Takeover Proposal
except in connection with a termination of this Agreement as set forth in
Section 7.1(e). Nothing contained in this Section 5.9 shall prohibit the Company
from taking and disclosing to its stockholders a position contemplated by Rule
14e-2(a) promulgated under the Exchange Act or from making any disclosure to the
Company's stockholders which, in the good faith reasonable judgment of the Board
of Directors of the Company after consultation with outside counsel, is required
under applicable law, provided that, except as otherwise permitted in this
Section 5.9, the Company does not withdraw or modify, or propose to withdraw or
modify, its position with respect to the Merger or approve or recommend, or
propose to approve or recommend, a Takeover Proposal. Notwithstanding anything
contained in this Agreement to the contrary, any

                                       37
<PAGE>

action by the Board of Directors permitted by, and taken in accordance with,
this Section 5.9 shall not constitute a breach of this Agreement by the Company.

     Section 5.10.  Public Announcements.  The Company and Parent will consult
                    --------------------
with and provide each other the opportunity to review and comment upon any press
release or other public statement or comment prior to the issuance of such press
release or other public statement or comment relating to this Agreement or the
transactions contemplated herein and shall not issue any such press release or
other public statement or comment without the prior approval of the other party
(which approval will not be unreasonably withheld), except as may be required by
law.

     Section 5.11.  Indemnification and Insurance.  (a)  From and after the
                    -----------------------------
Effective Time, Parent shall, and shall cause the Surviving Corporation to,
indemnify and hold harmless each present and former director and officer of the
Company determined as of the Effective Time (the "Indemnified Parties"), against
                                                  -------------------
any costs or expenses (including reasonable attorneys' fees), judgments, fines,
losses, claims, damages or liabilities (collectively, "Costs") incurred in
                                                       -----
connection with any claim, action, suit, proceeding or investigation, whether
civil, criminal, administrative or investigative, arising out of or pertaining
to matters existing or occurring at or prior to the Effective Time (including
without limitation in connection with the transactions contemplated by this
Agreement), whether asserted or claimed prior to, at or after the Effective
Time, to the fullest extent permitted under DGCL (and the Surviving Corporation
shall also advance expenses as incurred to the fullest extent permitted under
applicable law, provided the Person to whom expenses are advanced provides an
undertaking to repay such advances if it is ultimately determined that such
Person is not entitled to indemnification).

     (b)  Any Indemnified Party wishing to claim indemnification under paragraph
(a) of this Section 5.11, upon learning of any such claim, action, suit,
proceeding or investigation, shall promptly notify the Surviving Corporation
thereof, but the failure to so notify shall not relieve the Surviving
Corporation of any liability it may have to such Indemnified Party if such
failure does not materially prejudice the Surviving Corporation. In the event of
any such claim, action, suit, proceeding or investigation (whether arising
before or after the Effective Time), the Surviving Corporation shall have the
right to assume the defense thereof and the Surviving Corporation shall not be
liable to such Indemnified Parties for any legal expenses of other counsel or
any other expenses subsequently incurred by such Indemnified Parties in
connection with the defense thereof, except that if the Surviving Corporation
elects not to assume such defense or counsel for the Indemnified Parties advises
that there are issues which raise conflicts of interest between the Surviving
Corporation and the Indemnified Parties, the Indemnified Parties may retain
counsel satisfactory to them, and the Surviving Corporation shall pay all
reasonable fees and expenses of such counsel for the Indemnified Parties
promptly as statements therefor are received.

     (c)  For a period of six years after the Effective Time, Parent shall cause
