4.  Plan Administration

  (a) Except as otherwise determined by the Board, the Plan shall be
administered by the Committee.  The Board, or the Committee to the extent
determined by the Board, shall periodically make determinations with respect to
the participation of Employees in the Plan and, except as otherwise required by
law or this Plan, the grant terms of Awards including vesting schedules, price,
length of relevant performance, restriction or option period, dividend rights,

5.  Stock Subject to the Provisions of this Plan

  (a) The stock subject to the provisions of this Plan shall be shares of
authorized but unissued Common Stock and shares of Common Stock held as treasury
stock, subject to adjustment in accordance with the provisions of Section 10,
and subject to Section 5(b) below, the total number of shares of Common Stock
available for grants of Awards in any Plan Year shall not exceed 2% of the
outstanding Common Stock as reported in the Corporation's Annual Report on Form
10-K for the fiscal year ending immediately prior to such Plan Year.

  (b) There shall be available for Awards under the Plan in any Plan Year, in
addition to shares available for grant under paragraph (a) of this Section 5,
all of the following:  (i) any unused portion of the limit set forth in
paragraph (a) of this Section 5 for any prior Plan Year; (ii) shares represented
by Awards which are cancelled, forfeited, surrendered, terminated, paid in cash
or expire unexercised; (iii) the excess amount of variable Awards which become
fixed at less than their maximum limitations; (iv) any shares of Common Stock
that are used to pay the purchase price or any withholding taxes associated
therewith upon the exercise of an option, to the extent such shares result in
the grant of a replacement option; provided, however, that the total number of
shares of Common Stock which may be available for Awards under the Plan Year may
not exceed 5% of the outstanding Common Stock as reported in the Corporation's
Annual Report on Form 10-K for the fiscal year ending immediately prior to the
applicable Plan Year.

  (c) The exercise of an option or stock appreciation right granted in tandem
therewith will reduce proportionately the amount of shares subject to the tandem
stock appreciation right or option.  In addition, any shares ceasing to be
subject to the related option or right because of such reduction shall not
increase the number of shares of Common Stock available for future Awards
granted under the Plan. The grant of a performance or restricted share unit
Award shall be deemed to be equal to the maximum number of shares which may be
issued under the Award.  Where the value of an Award is variable on the date it
is granted, the value shall be deemed to be the maximum limitation of the Award.
Awards payable solely in cash will not reduce the number of shares available for
Awards granted under the Plan.


6.  Awards Under this Plan

  As the Board or Committee may determine, the following types of Awards and
other Common Stock-based Awards may be granted under this Plan on a stand alone,
combination or tandem basis:

  (a) Stock Option.  A right to buy a specified number of shares of Common Stock
at a fixed exercise price during a specified time, all as the Committee may
determine; provided that the exercise price of any option shall not be less than
100% of the Fair Market Value of the Common Stock on the date of grant of such
Award; provided further that no more than 3,240,000 stock options and stock
appreciation rights in the aggregate (except that a stock option issued in
tandem with a stock appreciation right shall be counted as one stock option for
purposes of this maximum) may be granted to any Employee during any five-year
period.

  (b) Incentive Stock Option.  An Award in the form of a stock option which
shall comply with the requirements of Section 422 of the Code or any successor
Section of the Code as it may be amended from time to time.  Subject to
adjustment in accordance with the provisions of Section 10, the aggregate number
of shares which may be subject to incentive stock option Awards under this Plan
shall not exceed 16,200,000 shares, subject in any Plan Year to the limitations
of Section 5 of this Plan.

                                       4
<PAGE>

  (c) Stock Appreciation Right.  A right to receive the excess of the Fair
Market Value of a share of Common Stock on the date the stock appreciation right
is exercised over the Fair Market Value of a share of Common Stock on the date
the stock appreciation right was granted; provided that no more than 3,240,000
stock options and stock appreciation rights in the aggregate (except that a
stock appreciation right issued in tandem with a stock option shall be counted
as one stock option for purposes of this maximum) may be granted to any
Participant during any five-year period.

  (d) Restricted and Performance Share.  A transfer of Common Stock to a
Participant, subject to such restrictions on transfer or other incidents of
ownership, or subject to specified performance standards, for such periods of
time as the Committee may determine; provided that no more than 1,134,000
performance shares (determined based upon the maximum number of shares of Common
Stock that may be earned) may be granted to any Employee during any five-year
period.

  (e) Restricted and Performance Share Unit.  A fixed or variable share or
dollar-denominated unit subject to conditions of vesting, performance and time
of payment as the Committee may determine, which are valued at the Committee's
discretion in whole or in part by reference to, or otherwise based on, the Fair
Market Value of Common Stock and which may be paid in Common Stock, cash or a
combination of both.

  (f) Dividend or Equivalent Right.  A right to receive dividends or their
equivalent in value in Common Stock, cash or in a combination of both with
respect to any new or previously existing Award.

  (g) Stock Award.  An unrestricted transfer of ownership of Common Stock which
may only be made to Employees other than Employees who are officers or directors
of the Corporation for purposes of Section 16 of the Exchange Act.

  (h) Other Stock-Based Awards.  Other Common Stock-based Awards which are
related to or serve a similar function to those Awards set forth in this Section
6.

  No Common Stock shall be issued pursuant to any Award unless consideration at
least equal to the par value thereof has been received by the Corporation in the
form of cash, services rendered or property.

  The Committee may from time to time, establish performance criteria with
respect to an Award.  The performance criteria or standards may be based upon
(i) earnings per share, (ii) return on average assets or (iii) return on average
equity.  Performance standards shall be determined by the Committee in its sole
discretion and may be absolute in their terms or measured against or in
relationship to other companies comparably, similarly or otherwise situated and
may be based on or adjusted for any other objective goals, events, or
occurrences established by the Committee, including earnings, earnings growth,
revenues, expenses, stock price, market share, charge-offs, loan loss reserves,
reductions in non-performing assets, return on assets, return on equity or
return on investment, regulatory compliance, satisfactory internal or external
audits, improvement or financial ratings, achievement of balance sheet or income
statement objectives, extraordinary charges, losses from discontinued
operations, restatements and accounting changes and other unplanned special
charges such as restructuring expenses, acquisition expenses including goodwill,
unplanned stock offerings and strategic loan loss provisions.  Such performance
standards may be particular to a line of business, subsidiary or other unit or
may be based on the performance of the Corporation generally.

7.  Award Summaries

  Each Award under the Plan shall be evidenced by an Award Summary.  Delivery of
an Award Summary to each Participant shall constitute an agreement, subject to
Section 4(d) and Section 9 hereof, between the Corporation and the Participant
as to the terms and conditions of the Award.


8.  Other Terms and Conditions

  (a) Assignability.  Except to the extent permitted by Rule 16b-3 under the
Exchange Act, or Section 422 of the Code, and as otherwise provided in the Award
Summary, no Award shall be assignable or transferable except by will, by the
laws of descent and distribution or pursuant to a qualified domestic relations
order as defined by the Code, and during the lifetime of a Participant, the
Award shall be exercisable only by such Participant or such Participant's
guardian, legal representative, or assignee pursuant to a qualified domestic
relations order.  In the event that any Award is thereafter transferred as
permitted by the preceding sentence, the permitted transferee thereof shall be
deemed the Award recipient hereunder.  Stock options, incentive stock options
and stock appreciation rights shall be exercisable during the transferee's
lifetime only by the Award recipient or by the Award recipient's guardian, legal
representative or similar person.

  (b) Termination of Employment.  The Committee shall determine the disposition
of the grant of each Award in the event of the retirement, disability, death or
other termination of a Participant's employment.

  (c) Rights As A Stockholder.  A Participant shall have no rights as a
stockholder with respect to shares covered by an Award until the date the
Participant or his nominee, or guardian or legal representative is the holder of
record.  No adjustment will be made for dividends or other rights for which the
record date is prior to such date.

  (d) No Obligation To Exercise.  The grant of an Award shall impose no
obligation upon Participant to exercise the Award.

  (e) Payments By Participants.  The Committee may determine that Awards for
which a payment is due from a Participant may be payable: (i) in U.S. dollars by
personal check, bank draft or money order payable to the order of the
Corporation, by money transfers or direct account debits; (ii) through the
delivery or deemed delivery based on attestation to the ownership of shares of
Common Stock with a Fair Market Value equal to the total payment due from the
Participant; (iii) by a combination of the methods described in (i) and (ii)
above; or (iv) by such other methods as the Committee may deem appropriate.

  (f) Withholding.  Except as otherwise provided by the Committee, (i) the
deduction of withholding and any other taxes required by law will be made from
all amounts paid in cash and (ii) in the case of payments of Awards in shares of
Common Stock, the Participant shall be required to pay the amount of any taxes
required to be withheld prior to receipt of such stock, or alternatively, a
number of shares the Fair Market Value of which equals the amount required to be
withheld may be deducted from the payment.  The Committee may provide for shares
of Common Stock to be withheld for tax withholding purposes in excess of the
required minimum amount but not in excess of a Participant's maximum marginal
tax rate.

  (g) Restrictions on Sale and Exercise.  With respect to Employees who are
officers and directors for purposes of Section 16 of the Exchange Act, and if
required to comply with rules promulgated thereunder, (i) no Award providing for
exercise, a vesting period, a restriction period or the attainment of

                                       6
<PAGE>

performance standards shall permit unrestricted ownership of Common Stock by the
Participant for at least six months from the date of grant, and (ii) Common
Stock acquired pursuant to this Plan (other than Common Stock acquired as a
result of the granting of a "derivative security") may not be sold for at least
six months after acquisition.


9.  Amendments

  The Board may amend, suspend or discontinue the Plan at any time, and prior to
a Change of Control (as defined in Section 12(b)) amend any or all Award
Summaries granted under the Plan to the extent permitted by law.  Any such
action of the Board may be taken without the approval of the Corporation's
stockholders, but only to the extent that such stockholder approval is not
required by applicable law or regulation, including specifically Rule 16b-3 of
the Securities and Exchange Commission.


10. Recapitalization

  The aggregate number of shares of Common Stock as to which Awards may be
granted to Participants, the number of shares thereof covered by each
outstanding Award, and the price per share thereof in each such Award, shall all
be proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock resulting from a subdivision or consolidation of shares
or other capital adjustment, or the payment of a stock dividend or other
increase or decrease in such shares, effected without receipt of consideration
by the Corporation, or other change in corporate or capital structure; provided,
however, that any fractional shares resulting from any such adjustment shall be
eliminated.  The Committee may also make the foregoing changes and any other
changes, including changes in the classes of securities available, to the extent
it is deemed necessary or desirable to preserve the intended benefits of the
Plan for the Corporation and the Participants in the event of any other
reorganization, recapitalization, merger, consolidation, spinoff, extraordinary
dividend or other similar transaction.


11. No Right to Employment

  No person shall have any claim or right to be granted an Award, and the grant
of an Award shall not be construed as giving a Participant the right to be
retained in the employ of the Corporation or a Subsidiary.  Further, the
Corporation and each Subsidiary expressly reserve the right at any time to
dismiss a Participant free from any liability, or any claim under the Plan,
except as provided herein or in any Award Summary issued hereunder.


12. Change of Control

  (a) Notwithstanding anything contained in the Plan or any Award Summary to the
contrary, in the event of a Change of Control, as defined below, the following
shall occur with respect to any and all Awards outstanding as of such Change of
Control:

      (i) automatic maximization of performance standards, lapse of all
  restrictions and acceleration of any time periods relating to the exercise,
  realization or vesting of such Awards so that such Awards may be immediately
  exercised, realized or vested in full on or before the relevant date fixed in
  the Award Summary;

                                       7
<PAGE>

      (ii)  performance shares or performance units shall be paid entirely in
  cash; provided, however, that if any right granted pursuant to this Section
  12(a)(ii) would make a Change of Control transaction ineligible for pooling-
  of-interests accounting under APB No. 16 that but for the nature of such grant
  would otherwise be eligible for such accounting treatment, the Board or the
  officer or officers authorized by a resolution of the Board shall have the
  ability to substitute for the cash payable pursuant to such right Common Stock
  with a Fair Market Value equal to the cash that would otherwise be payable
  thereunder;

      (iii) if a Participant's employment terminates following a Change of
  Control, any Options held by the Participant may be exercised by the
  Participant until the earlier of three months after such termination of
  employment (or the later date following termination of employment specified in
  the relevant Award Summary), or the expiration date of such Options; and

      (iv)  all Awards become noncancellable.

  (b) A "Change of Control" of the Corporation shall be deemed to have occurred
upon the happening of any of the following events:

      (I)   The acquisition by any individual, entity or group (within the
meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) (a "Person") of
beneficial ownership (within the meaning of Rule 13d-3 promulgated under the
Exchange Act) of 20% or more of either (A) the then outstanding shares of Common
Stock of the Corporation (the "Outstanding Corporation Common Stock") or (B) the
combined voting power of the then outstanding voting securities of the
Corporation entitled to vote generally in the election of directors (the
"Outstanding Corporation Voting Securities"), provided, however, that for
purposes of this subsection (I), the following acquisitions shall not constitute
a Change of Control: (A) any acquisition directly from the Corporation, (B) any
acquisition by the Corporation, (C) any acquisition by any employee benefit plan
(or related trust) sponsored or maintained by the Corporation or any corporation
controlled by the Corporation or (D) any acquisition by any corporation pursuant
to a transaction which complies with clauses (A), (B) and (C) of subsection
(III) of this Section 12(b); or

      (II)  Individuals who, as of the date hereof, constitute the Board (the
"Incumbent Board") cease for any reason to constitute at least a majority of the
Board, provided, however, that any individual becoming a director subsequent to
the date hereof whose election, or nomination for election by the Corporation's
shareholders, was approved by a vote of at least a majority of the directors
then comprising the Incumbent Board shall be considered as though such
individual were a member of the Incumbent Board, but excluding, for this
purpose, any such individual whose initial assumption of office occurs as a
result of an actual or threatened election contest with respect to the election
or removal of directors or other actual or threatened solicitation of proxies or
consents by or on behalf of a Person other than the Board; or

      (III) Consummation of a reorganization, merger or consolidation or sale or
other disposition of all or substantially all of the assets of the Corporation
(a "Business Combination"), in each case, unless, following such Business
Combination, (A) all or substantially all of the individuals and entities who
were the beneficial owners, respectively, of the Outstanding Corporation Common
Stock and Outstanding Corporation Voting Securities immediately prior to such
Business Combination beneficially own, directly or indirectly, more than 50% of,
respectively, the then outstanding shares of common stock and the combined
voting power of the then outstanding voting securities entitled to vote
generally in the election of directors, as the case may be, of the corporation
resulting from such Business Combination (including, without limitation, a
corporation which as a result of such transaction owns the Corporation or all or
substantially all of the Corporation's assets either directly or through one or
more subsidiaries) in

                                       8
<PAGE>

substantially the same proportions as their ownership, immediately prior to such
Business Combination of the Outstanding Corporation Common Stock and Outstanding
Corporation Voting Securities, as the case may be, (B) no Person (excluding any
corporation resulting from such Business Combination or any employee benefit
plan (or related trust) of the Corporation or such corporation resulting from
such Business Combination) beneficially owns, directly or indirectly, 20% or
more of, the corporation resulting from such Business Combination or the
combined voting power of the then outstanding voting securities of such
corporation except to the extent that such ownership existed prior to the
Business Combination and (C) at least a majority of the members of the board of
directors of the corporation resulting from such Business Combination were
members of the Incumbent Board at the time of the execution of the initial
agreement, or of the action of the Board, providing for such Business
Combination; or

      (IV)  Approval by the shareholders of the Corporation of a complete
liquidation or dissolution of the Corporation.


13.  Governing Law

  To the extent that federal laws do not otherwise control, the Plan shall be
construed in accordance with and governed by the law of the State of Delaware.


14.  Supplemental Plans

  The Board shall have the authority to adopt plans, supplemental to this Plan,
covering Employees residing outside the United States, including but not limited
to the United Kingdom.


15.  Savings Clause

  This Plan is intended to comply in all aspects with applicable law and
regulation, including, with respect to those Employees who are officers or
directors for purposes of Section 16 of the Exchange Act, Rule 16b-3 of the
Securities and Exchange Commission.  In case any one or more of the provisions
of this Plan shall be held invalid, illegal or unenforceable in any respect
under applicable law and regulation (including Rule 16b-3), the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby and the invalid, illegal or unenforceable provision
shall be deemed null and void; however, to the extent permissible by law, any
provision which could be deemed null and void shall first be construed,
interpreted or revised retroactively to permit this Plan to be construed in
compliance with all applicable laws (including Rule 16b-3) so as to foster the
intent of this Plan.


16.  Effective Date and Term

  The effective date of this Plan is February 16, 1999.  The Plan shall remain
in effect until terminated by the Board.
