     Not applicable.

ITEM 5.   Interests of Named Experts and Counsel.

     Not applicable.

ITEM 6.   INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Sections 1741 and 1742 of the Pennsylvania Business Corporation Law of
1988, as amended (the "PBCL") provide that a business corporation may indemnify
directors and officers against liabilities they may incur as such provided that
the particular person acted in good faith and in a manner he or she reasonably
believed to be in, or not opposed to, the best interests of the corporation,
and, with respect to any criminal proceeding, had no reasonable cause to believe
his or her conduct was unlawful.  In general, the power to indemnify under these
sections does not exist in the case of actions against a director or officer by
or in the right of the corporation if the person otherwise entitled to
indemnification shall have been adjudged to be liable to the corporation unless
it is judicially determined that, despite the adjudication of liability but in
view of all the circumstances of the case, the person is fairly and reasonably
entitled to indemnification for specified expenses.  The corporation is required
to indemnify directors and officers against expenses they may incur in defending
actions against them in such capacities if they are successful on the merits or
otherwise in the defense of such actions.

     Section 1713 of the PBCL permits the shareholders to adopt a bylaw
provision relieving a director (but not an officer) of personal liability for
monetary damages except where (i) the director has breached the applicable
standard of care, and (ii) such conduct constitutes self-dealing, willful
misconduct or recklessness.  The statute provides that a director may not be
relieved of liability for the payment of taxes pursuant to any federal, state or
local law or responsibility under a criminal statute.

     Section 1746 of the PBCL grants a corporation broad authority to indemnify
its directors, officers and other agents for liabilities and expenses incurred
in such capacity, except in circumstances where the act or failure to act giving
rise to the claim for indemnification is determined by a court to have
constituted willful misconduct or recklessness.

     Section 3.01(b) of the Registrant's Bylaws provides that a director shall
not be personally liable for monetary damages for any action taken, or any
failure to take any action, unless the director has breached or failed to
perform the duties of his or her office and the breach or failure to perform
constitutes self-dealing, willful misconduct or recklessness.  These provisions
do not apply to the responsibility or liability of a director pursuant to any
criminal statute or the liability of a director for the payment of taxes
pursuant to local, state or federal law.

     Section 7.01 of the Registrant's Bylaws provides that the Registrant shall
indemnify directors and officers against any liability incurred in connection
with any proceeding in which the director or officer may be involved by reason
of the fact that such person was serving in an indemnified capacity, including
without limitation liabilities resulting from any actual or alleged breach or
neglect of duty, error, misstatement or misleading statement, negligence, gross
negligence or act giving rise to strict products liability, except where such
indemnification is expressly prohibited by applicable law or where the conduct
has been determined to constitute willful misconduct or recklessness.

     Section 7.04 of the Registrant's Bylaws provides that the Registrant may
maintain insurance or use any other arrangement to satisfy or secure its
indemnification obligations.

_________________

     (1)  In lieu of an opinion of counsel concerning compliance with the
          requirements of the Employee Retirement Income Security Act of 1974,
          as amended ("ERISA"), and an Internal Revenue Service ("IRS")
          determination letter that the Plan is qualified under Section 401 of
          the Internal Revenue Code of 1986, as amended, the Registrant hereby
          undertakes to submit the Plan and any amendments thereto to the IRS in
          a timely manner and will make all changes required by the IRS in order
          to qualify the Plan.

ITEM 9.   Undertakings.

     (a)  The undersigned registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement:

               (i)    To include any prospectus required by Section 10(a)(3) of
     the Securities Act of 1933;

               (ii)   To reflect in the prospectus any facts or events arising
     after the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement; and

               (iii)  To include any material information with respect to the
     plan of distribution not previously disclosed in the registration statement
     or any material change to such information in the registration statement;

                                     II-3
<PAGE>
 
          Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this
section do not apply if the information required to be included in a post-
effective amendment by those paragraphs is contained in periodic reports filed
by the Registrant pursuant to Section 13 or Section 15(d) of the Securities
Exchange Act of 1934 that are incorporated by reference in the registration
statement.

          (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

          (3)  To remove from registration by means of a post-effective
amendment any of the securities being registered that remain unsold at the
termination of the offering.

     (b)  The undersigned registrant hereby undertakes that, for the purpose of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and each filing of the Plan's respective annual
reports pursuant to Section 15(d) of the Securities Exchange Act of 1934) that
is incorporated by reference in this registration statement shall be deemed to
be a new registration statement relating to the securities offered therein and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

     (c)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

                              STATEMENT OF PURPOSE
                              --------------------


     Sec. 1.01  Background and Purpose.  SEI Corporation (the "Company")
                ----------------------                                  
established effective January 1, 1983 and has since maintained the SEI
Corporation Savings and Investment Plan (the "Plan").  The purposes of the Plan
have been to enable eligible employees of the Company to increase personal long-
term savings through the tax deferral opportunities offered under section 401(k)
of the Internal Revenue Code of 1986, as amended (the "Code"), from
contributions made by the Company and from the results generated by investment
of the assets of the Plan in the tax-sheltered environment offered by the Plan's
trust.

     Effective as of January 1, 1985, the SEI Profit Sharing Plan was merged
with and into this Plan.  Effective as of April 1, 1988, the assets and
liabilities of the SEI Corporation Tax Credit Employee Stock Ownership Plan (the
"ESOP") in the form of the participant account balances thereunder were
transferred directly to this Plan.  Effective as of January 1, 1989, the Plan
has been amended and restated in the form set forth herein (i) to liberalize the
eligibility requirements for Company matching contributions, (ii) to offer
additional investment options, (iii) to reflect the merger of the ESOP, and (iv)
to comply with the requirements of the Tax Reform Act of 1986 and other recent
changes in the law.  The Plan as so amended and restated has been renamed the
"SEI Corporation Capital Accumulation Plan."

     Effective as of January 1, 1990, the National FSI, Inc. 401(k) Savings Plan
(the "FSI Plan") is being merged into the Plan.  Employees of SEI Corporation
who were formerly employees of National FSI, Inc., and who were participants in
or eligible to participate in the FSI Plan immediately prior to the date of the
merger, shall automatically become Participants in the Plan as of such date.
Employees of SEI Corporation shall receive credit for all service with National
FSI, Inc. for purposes of eligibility to participate in this Plan.  Salary
Deferral Contributions made to the FSI Plan shall be allocated to a
Participant's Salary Deferral Account, Direct Employer Contributions made to the
FSI Plan shall be allocated to a Participant's Matching Contribution Account and
Non-Deductible Voluntary Contributions made to the FSI Plan shall be allocated
to a Participant's Voluntary Contribution Account under this Plan.

                                                       -------------------------

     In accordance with the provisions of Section 17.02, the Plan was amended,
effective as of April 1, 1993, to terminate the ESOP which was maintained as a
separate and distinct portion of the Plan since it was merged with and into the
Plan on April 1, 1988. Upon termination of the ESOP and at the election of ESOP
participants, ESOP accounts were (a) distributed in cash or Company Stock or (b)
directly transferred, in cash, to the remaining portion of the Plan and invested
at the direction of the participant in accordance with Article IX herein.

     Effective as of January 1, 1994, except to the extent designated otherwise,
the Plan was amended to (i) reduce the two-year service requirement for
eligibility to receive an allocation of a profit-sharing contribution to a one-
year service requirement, (ii) to clarify that profit-sharing contributions may
be designated as qualified non-elective contributions, as necessary to meet the
requirements of section 401(k)(3)(A) of the Code and may be allocated only to
non-highly compensated employees in such case and (iii) to eliminate the spousal
consent requirement to the extent possible for purposes of an in-service
withdrawal, hardship withdrawals or Plan loan.

     Effective as of January 1, 1992, except to the extent designated otherwise,
the Plan has been amended and restated in the form set forth herein (i) to
eliminate a participant's right to make after-tax contributions to the Plan as
of January 1, 1995 and (ii) to comply with applicable requirements of the
Omnibus Budget Reconciliation Act of 1993 and other recent changes in the law.

     Sec. 1.02  Qualification Under the Internal Revenue Code. It is intended
                ---------------------------------------------                
that the Plan continue to be a qualified plan within the meaning of section
401(a) of the Code, that the requirements of section 401(k) of the Code be
satisfied as to that portion of the Plan represented by contributions made
pursuant to participant salary deferral elections, and that the trust or other
funding vehicle associated with the Plan be exempt from federal income taxation
pursuant to the provisions of section 501(a) of the Code.  Subject to the
provisions of Article IV of the Plan the assets of the Plan shall be applied
exclusively for the purposes of providing benefits to participants and
beneficiaries under the Plan and for defraying expenses incurred in the
administration of the Plan and its corresponding trust or other funding vehicle.

     Sec. 1.03  Plan Documents.  The Plan consists of the Plan document as set
                --------------                                                
forth herein, and any amendment thereto.  Certain provisions relating to the
Plan and its operation are contained

in the corresponding Trust Agreement (or documents establishing any other
funding vehicle for the Plan), and any amendments, supplements, appendices and
riders to any of the foregoing. The benefits of participants who separated from
service with the Company prior to January 1, 1989 shall, unless otherwise
specified herein, be determined under the terms of the Plan as in effect at the
time of such separation from service. Descriptive material relating to the Plan
shall not be considered a part of the Plan, and in the event of any conflict
between such descriptive material and the Plan, the text of the Plan shall
govern.

at Title 29, Code of Federal Regulations, section 2530.200b-2, and shall mean
(a) each hour for which an employee is paid or entitled to payment for the
performance of duties for the Employer or an Affiliated Company during the Plan
Year, (b) each hour for which an employee is paid or entitled to payment by the
Employer or an Affiliated Company on account of a period of time during which no
duties are performed (irrespective of whether or not the employment relationship
has terminated) due to vacation, holiday, illness, incapacity (including
disability), layoff, jury or military duty, or leave of absence, and (c) each
hour for which back pay, irrespective of mitigation of damages, is either
awarded or agreed to by the Employer or an Affiliated Company. Hours of Service
shall be credited to the Plan Year in which earned, regardless of when
determined or awarded. Notwithstanding the foregoing, except as provided in the
following sentence, (i) not more than five hundred one (501) Hours of Service
shall be credited to an employee on account of any single continuous period
during which the employee performs no duties for the Employer or an Affiliated
Company; (ii) no credit shall be granted for any period with respect to which an
employee receives payment or is entitled to payment under a plan maintained
solely for the purpose of complying with applicable workmen's compensation or
disability insurance laws; and (iii) no credit shall be granted for a payment
which solely reimburses an employee for medical or medically related expenses
incurred by the employee. Each week of absence for military service in the armed
forces of the United States from which service the employee returns to the
Employer or an Affiliated Company within the period during which he has legally
protected reemployment rights shall count as a number of Hours of Service equal
to the number of Hours of Service that would have been credited to the employee
with respect to the employee's customary week of employment during the month
immediately preceding the date on which absence for military service commenced.
Service rendered at overtime or other premium rates shall be credited at the
rate of one (1) Hour of Service for each hour for which pay is earned,
regardless of the rate of compensation in effect with respect to such hour.

     For the purposes of this Section, the term "employee" means any person with
whom the Employer or an Affiliated Company maintains an employer-employee
relationship under general principles of law, or under the provisions of section
414(n) of the Code if section 414(n)(5) does not apply to negate the
applicability of section 414(n).

term, (ii) the services of the subject person are provided pursuant to an

or (b) the first day of the first payroll period beginning in the month
following his Employment Commencement Date.

     Sec. 3.02  Procedure for and Effect of Admission.  Each Employee who
                -------------------------------------

provisions of the Plan, the corresponding Trust Agreement, and to all amendments
to such instruments.

     Sec. 3.03  Changes in Status.  A Participant who ceases to be employed as

the Plan as an Active Participant until he again becomes an Employee at which
time he will immediately again become an Active Participant.

     Sec. 4.01  Employer Contributions.
                ---------------------- 

          (a)  Salary Deferral Contributions.  The Employer shall contribute to
               -----------------------------                                   
the Plan, with respect to each Plan Year, an amount equal to the aggregate
Salary Deferral Contributions of its Employees for such Plan Year, as determined
pursuant to Salary Deferral elections in force pursuant to Article VII.

          (b)  Matching Contributions.  Effective January 1, 1990, beginning
               ----------------------                                       
with the second January 1 following the Participant's Employment Commencement
Date, provided that the Participant has completed a Year of Service in the Plan
Year preceding such January 1, the Employer shall contribute to the Plan, an
amount equal to such percentage of the Salary Deferral Contributions of up to
four percent (4%) of the Compensation of each Active Participant, as the Board
of Directors, in its sole discretion, shall determine; provided, however, that
if a Participant is ineligible to make Salary Deferral Contributions for a
portion of the Plan Year because of the limitation imposed by section 402(g) or
401(k)(3)(A) of the Code, such Matching Contribution shall be computed as though
the Participant's Salary Deferral Contributions were made equally throughout the
Plan Year.  Notwithstanding the foregoing, a Participant who was employed before
December 31, 1989 shall become eligible for Matching Contributions no later than
the date on which he completes two Years of Service.  If a Participant fails to
complete 1,000 Hours of Service in the Plan Year preceding the January 1 as of
which he first becomes eligible for Matching Contributions, he shall become
eligible as of any succeeding January 1 following a Plan Year in which he meets
the 1,000 Hour of Service requirement.

          (c)  Profit-Sharing Contributions.  Effective January 1, 1989, for
               ----------------------------
each Plan Year, the Employer shall contribute to the Plan such amounts, if any,
as the Board of Directors, in its sole discretion, shall determine. The Board of
Directors shall designate all or a portion of such amount as a qualified
nonelective contribution (as defined in section 401(m)(4)(C) of the Code), if it
determines, in its sole discretion, that such a contribution is needed to meet
the requirements of section 401(k)(3)(A) of the Code.

          (d)  Timing of Contributions.
               ----------------------- 

               (1)  To the extent practicable, contributions made pursuant to
     Section 4.01(a) shall be made at least monthly and shall not be made later
     than the date referred to in paragraph (2) below, provided, however, that
     no Salary Deferral Contribution shall be held by the Employer without
     contributing the same to the Plan for a period longer than (i) sixty (60)
     days, or, (ii) if shorter, the longest period that is permissible under
     regulations published under section 401(k) of the Code, and, in any event,
     amounts contributed pursuant to Section 4.01(a) with respect to any Plan
     Year shall be deemed credited to the Participant's Salary Deferral Account
     not later than the last day of such Plan Year.

               (2)  All contributions made pursuant to this Section 4.01 shall
     be made not later than the date established for the filing of the
     Employer's federal income tax return for the fiscal year of the Employer
     ending with or within the Plan Year for which the contribution is made
     (including any extensions of such filing date).

     Sec. 4.02  Contingent Nature of Contributions.  Each contribution made by
                ----------------------------------                            
the Employer pursuant to the provisions of Section 4.01 is hereby made expressly
contingent on the deductibility thereof for federal income tax purposes for the
fiscal year with respect to which such contribution is made. Each such
contribution is further similarly contingent upon the maintenance of qualified
status by the Plan for the year with respect to which such contribution is made,
to the extent that the loss of qualified status would deprive the Employer of
the deduction taken for such contribution.

     Sec. 4.03  Exclusive Benefit; Refund of Contributions.  All contributions
                ------------------------------------------                    
made by the Employer are made for the exclusive benefit of the Participants and
their Beneficiaries, and such contributions shall not be used for, nor diverted,
to purposes other than for the exclusive benefit of the Participants and their
Beneficiaries (including the costs of maintaining and administering the Plan and
corresponding trust).  Notwithstanding the foregoing, to the extent that such
refunds do not, in themselves, deprive the Plan of its qualified status, refunds
of contributions shall be made to the Employer under the following circumstances
and subject to the following limitations:

                                                                 SEI CORPORATION

                                                       -------------------------

          (a)  Initial Nonqualification.  If the Plan is determined not to
               ------------------------                                   
satisfy the qualification requirements of section 401(a) of the Code, and if the
Company declines to amend the Plan to satisfy such qualification requirements of
section 401(a) of the Code, contributions made with respect to any period of
nonqualification and prior to the determination that the Plan has failed to
qualify shall be returned to the Employer.

          (b)  Disallowance of Deduction.  To the extent that a federal income
               -------------------------                                      
tax deduction is disallowed for any contribution made by an Employer, the
Trustee shall refund to the Employer the amount so disallowed within one (1)
year of the date of such disallowance.

          (c)  Mistake of Fact.  In the case of a contribution which is made in
               ---------------                                                 
whole or in part by reason of a mistake of fact (for example, incorrect
information as to the eligibility or compensation of an Employee, or a
mathematical error), so much of the Employer contribution as is attributable to
the mistake of fact shall be returnable to the Employer upon demand, upon
presentation of evidence of the mistake of fact to the Trustee and of
calculations as to the impact of such mistake.  Demand and repayment must be
effectuated within one (1) year after the payment of the contribution to which
the mistake applies.

     In the event that any refund is paid to the Employer hereunder, such refund
shall be made without interest and shall be deducted from among the Accounts of
the Participants. To the extent that the amount of the refund can be identified
to one or more specific Participants and Accounts of such Participants, it shall
be deducted directly from each such Account in the amount identifiable thereto.
To the extent any such refund is attributable to Salary Deferral Contributions
such refund, upon receipt by the Employer, shall be promptly paid over (net of
such taxes as must be withheld by law) to the Participant from whose Account
such amount was returned (or to the Participant's Beneficiary in the case of the
death of the Participant).

     Notwithstanding any other provision of this Section, no refund shall be
made to the Employer which is specifically chargeable to an Account of any
Participant in excess of one hundred percent (100%) of the amount in such
Account nor shall a refund be made by the Trustee of any funds, otherwise
subject to refund hereunder, which have been distributed to Participants, or
Beneficiaries. In the case that such distributions become refundable, the

               ----------------------------------------------------      
Voluntary Participant Contribution amounts set forth in any election to make
such contributions shall be tentative and shall become final only after the
Employer or the Plan Administrator has made such adjustments thereto as they (or
either of them) deem necessary to meet the requirements of Section 8.04.

          (b)  Distribution of Excess Amounts.  All amounts withheld or
               ------------------------------                          
contributed pursuant to an election to make Voluntary Participant Contributions
thereafter delivered to the Trustee shall be so delivered only if the Employer
in good faith believes that such amounts do not exceed the amounts permissible
pursuant to the limitations set forth in Section 8.04.  If any amount shall be
contributed or withheld from the Compensation of a Participant pursuant to an
election to make Voluntary Participant Contributions which exceeds the maximum
amount permissible pursuant to Section 8.04 for any Plan Year, then, prior to
the close of the following Plan Year, such excess amounts (and to the extent
required, any income allocable thereto) shall, in accordance with procedures to
be developed by the Plan Administrator, which procedures shall be consistent
with the requirements of section 401(m)(6) of the Code, be distributed to the
appropriate Participants, any other provision of the Plan to the contrary
notwithstanding.

     Sec. 5.06  Rollover Contributions.  With the approval of the Plan
                ----------------------                                
Administrator, the Plan shall accept on behalf of any Employee, whether or not
he has the requirements for participation in the Plan, the entire amount of cash
received (effective as of January 1, 1993 directly or indirectly) as a
distribution from, or payable by, another qualified trust forming a part of a
plan described in section 401(a) of the Code or from an individual retirement
program described in section 408 of the Code, but only if the deposit qualifies
as a tax-free rollover as defined in section 402 of the Code.  If the amount
received does not qualify as a tax-free rollover, the amount shall be refunded
to the Participant.  Rollover amounts shall be invested in accordance with the
provisions of Article IX.  Where necessary herein, rollover amounts shall be
treated as if an appropriate portion were credited to the Participant's Accounts
based upon the type of contribution or contributions giving rise to the amount
originally rolled over to this Plan.  An Employee who is not yet a Participant
shall be deemed a Participant only with respect to his rollover amount.

of a Participant pursuant to a Salary Deferral election which exceeds the
maximum amount permissible pursuant to Section 8.03(a) for any Plan Year, then,
prior to the close of the following Plan Year, such excess amounts (and to the
extent required any income allocable thereto) shall, in accordance with
procedures to be developed by the Plan Administrator, which procedures shall be
consistent with the requirements of section 401(k)(8) of the Code, either be
distributed to the appropriate Active Participants or, at the election of such
Participants, be treated as having been distributed and recontributed to the
Plan. Such distribution or distribution and recontribution may be made
notwithstanding any Plan provision to the contrary. Effective for Plan Years
beginning on or after January 1, 1993 or such later date as may be provided
under Treasury regulations, any Matching Contributions that such Participant has
received on account of his excess Salary Deferral Contributions shall be
forfeited and any such forfeited amounts shall be treated as a Matching
Contribution, made pursuant to Section 4.01(b), and reallocated, pursuant to
Section 6.02, to the Matching Contribution Accounts of Participants who are
eligible to share in Matching Contributions.

aggregate of all Salary Deferral Contributions are within the limitations of
said section 404(a) (after taking into account all other contributions made by
the Employer).

          (d)  The Dollar Limit.  Notwithstanding anything contained herein to

the contrary, no Participant shall be permitted to have Salary Deferral
Contributions made under this Plan together with elective deferrals (as defined

the limit imposed by section 402(g) of the Code for the calendar year in which
the deferrals occurred, the Plan Administrator shall notwithstanding any other
provision of the Plan distribute, by April 15 of the following calendar year,
the amount of Salary Deferral Contributions specified in the Participant's
claim, plus income thereon. The Participant's claim shall be in writing and
shall be submitted to the Plan Administrator no later than the March 1 following
the calendar year in which such deferrals occurred. Notwithstanding anything in
this Section 7.05(d) to the contrary, a Participant shall be deemed to have made
a claim for distribution of excess Salary Deferral Contributions from the Plan
to the extent that his Salary Deferral Contributions together with his elective
deferrals under any other plan or arrangement maintained by the Employer or an
Affiliated Company exceed the limit imposed by section 402(g) of the Code for
the calendar year. Effective for Plan Years beginning on or after January 1,
1993 or such later date as may be provided under Treasury regulations, any
Matching Contributions that such Participant has received on account of his
excess Salary Deferral Contributions shall be forfeited and any such forfeited
amounts shall be treated as a Matching Contribution, made pursuant to Section
4.01(b), and reallocated, pursuant to Section 6.02, to the Matching Contribution
Accounts of Participants who are eligible to share in Matching Contributions.

     Sec. 8.01  Definitions.  For purposes of this Article VIII, the following
                -----------                                                   
terms shall have the following definitions:

          (a)  "Actual Deferral Percentage" shall mean the ratio (expressed as a
percentage) of Salary Deferral Contributions (excluding any Salary Deferral
Contributions that are (1) taken into account in determining the Contribution

Contributions, made on behalf of the Employee for the Plan Year to the
Employee's Statutory Compensation for the Plan Year.  The Actual Deferral
Percentage of a Highly Compensated Employee who is a Participant under this Plan
and who has made elective deferrals under any other qualified cash or deferred
arrangement maintained by the Employer or an Affiliated Company pursuant to
section 401(k) of the Code shall be the sum of his deferral percentages under
all such plans (excluding plans that are not permitted to be aggregated under
Treas. Reg. (S)1.401(k)-1(b)(3)(ii)(B)).

          (b)  "Anniversary Date" shall mean the first day of the Plan Year.

          (c)  "Annual Addition" shall mean, for any Limitation Year, the sum

     (relating to post-retirement medical or life insurance benefit accounts for
     Key Employees) of the Code.

          For the purposes of this Section 8.01(c)(4), contributions to any
qualified defined contribution plan sponsored by the Employer or by an
Affiliated Company, and any forfeitures reallocated under any such plan, shall
be considered to be contributions or reallocable forfeitures, as the case may
be, under the Plan. Anything contained in this Section to the contrary
notwithstanding, a Participant's contributions pursuant to Section 5.05
(restoration contributions) or like contribution to any plan aggregated with the
Plan under the preceding sentence, or any contribution received by this Plan or
any such other plan that represents a rollover of a distribution received from
another plan shall not be considered a Participant contribution for the purposes
of this Section.

(expressed as a percentage) of the Contribution Percentages of Employees in a
group.

          (f)  "Contribution Percentage" shall mean the ratio (expressed as a

contributions constitute a matching contribution within the meaning of section
401(m)(4)(A) of the Code, and Voluntary Participant Contributions on behalf of

Plan Year.  For purposes of determining the Contribution Percentage, the
Employer or the Plan Administrator may take into account, in accordance with
Treasury regulations, Salary Deferral Contributions but only to the extent
necessary to satisfy the Average Contribution Percentage test, and only to the
extent that the Plan continues to satisfy the Average Actual Deferral Percentage
test without taking such Contributions into account.

          (g)  "Defined Benefit Fraction" shall be a fraction,

               (1)  the numerator of which is the sum of the projected
     annual benefits of the Participant under all defined benefit
     pension plans qualified under section 401(a) of the Code and
     sponsored by the Company and all

     multiplied by the dollar limitation in effect under section
     415(b)(1)(A) of the Code as to such Limitation Year, or (2) the
     product of (i) 1.4, multiplied by (ii) the amount which may be
     taken into account under subsection 415(b)(1)(B) of the Code with
     respect to such individual under the Plan for such Limitation
     Year.

               (3)  If the Plan is a Super Top-Heavy Plan, or if the
     Plan is a Top-Heavy Plan (but not a Super Top-Heavy Plan) and
     fails to meet the safe harbor rules in Section 13.04 of the Plan,
     "1.0" shall be substituted for "1.25" in Subsection (b) of this
     Section.

          (h)  "Defined Contribution Fraction" shall be a fraction,

               (1)  the numerator of which is the sum of the Annual
     Additions to the Participant's Account as of the close of the
     Limitation Period of reference, treating as an Annual Addition
     under the Plan all amounts which satisfy the definition of Annual
     Addition hereunder but which were accumulated under any other
     defined contribution plan qualified under section 401(a) of the
     Code and sponsored by the Company or any Affiliated Company, and

               (2)  the denominator of which is the sum of the
     denominator increments (as of the close of the Limitation Year)
     for all of the Participant's years of service with the Company or
     any Affiliated Company, where the denominator increment for each
     such year of service is the lesser of (1) the product determined
     by multiplying 1.25 by the dollar limitation in effect under
     section 415(c)(1)(A) of the Code for such year of service
     (determined without regard to subsection 415(c)(6) of the Code),
     or (2) the product determined by multiplying 1.4 by the amount
     which may be taken into account under subsection 415(c)(1)(B) of
     the Code (or subsections 415(c)(7), if applicable) with respect
     to such individual for such year.

               (2)  In the case of the Plan Year for which the
     relevant determination is being made, an employee not described

Defined Benefit Fraction, as such terms are defined in section 415 of the Code,
to exceed 1.0, or such other limitation as may be applicable under section 415
of the Code with respect to any combination of qualified plans without
disqualification of any such plan.

          (c)  Manner of Conformance.  In the event that the amount tentatively

Year exceeds the maximum amount permissible hereunder, there shall first be
returned to the Participant such portion of the Participant's contributions,
with income thereon, made during such Limitation Year to the Plan and any other
plan as is necessary to reduce the Annual Additions to his Account to the
maximum allowable hereunder.  If further reduction in the amount allocable to
the Participant's Account is required, the Participant's share of Employer
contributions for that Limitation Year shall be reduced to the extent necessary
to result in conformity to the limitations expressed herein.  To the extent a
Participant's Salary Deferral Contributions are reduced pursuant to this Section
8.02(c), such Salary Deferral Contributions, with income thereon, shall be
returned to the Participant as soon as administratively practicable.  The Plan
Administrator shall have full authority to take whatever corrective measures may
be necessary, including retroactive adjustment of Account balances, in order to
ensure compliance with the requirements of this Section and the underlying
requirements of section 415 of the Code.

     or such lesser amount as the Secretary of the Treasury shall prescribe to
     prevent the multiple use of this alternative limitation with respect to any
     Highly Compensated Employee.

          (b)  For purposes of determining the Actual Deferral Percentage of an
Employee who is a Highly Compensated Employee under Section 8.01(i)(1)(A) or
Section 8.01(i)(1)(C), the Salary Deferral Contributions and Statutory
Compensation of such a Highly Compensated Employee shall include the Salary
Deferral Contributions and Statutory Compensation of family members (as defined
in Section 8.01(i)(6)), and such family members shall be disregarded in
determining the Average Actual Deferral Percentage for Employees who are
Nonhighly Compensated Employees.

          (c)  The determination and treatment of the Salary Deferral
Contributions, and Actual Deferral Percentage of any Employee shall satisfy such
other requirements as may be prescribed by the Secretary of the Treasury.

          (d)  In the event that the Plan satisfies the requirements of section
410(b) of the Code (other than section 410(b)(2)(A)(ii) of the Code) only if
aggregated with one or more other plans of the Employer or an Affiliated
Company, or if one or more other plans of the Employer or an Affiliated Company
satisfy the requirements of section 410(b) of the Code only if aggregated with
the Plan, than Sections 8.03, 8.04 and 8.05 shall be applied as if all such
plans were a single plan.

     more than two (2) percentage points or such lesser amount as the Secretary
     of the Treasury shall prescribe to prevent the multiple use of this
     alternative limitation with respect to any Highly Compensated Employee.

          (b)  For purposes of this Article VIII, the Contribution Percentage
for any Employee who is a Highly Compensated Employee for the Plan Year and who
is eligible to have Matching Contributions, Participant Voluntary Contributions
or Salary Deferral Contributions allocated to his account under two or more
plans described in section 401(a) of the Code or arrangements described in
section 401(k) of the Code that are maintained by the Company or an Affiliated
Company shall be determined as if all Matching Contributions, Participant
Voluntary Contributions and Salary Deferral Contributions were made under a
single plan.

          (c)  In the event that the Plan satisfies the requirements of section
410(b) of the Code only if aggregated with one or more other plans, or if one or
more other plans satisfy the requirements of section 410(b) of the Code only if
aggregated with the Plan, then this Section shall be applied by determining the
Contribution Percentages of Employees as if all such plans were a single plan.

          (d)  For purposes of determining the Contribution Percentage of an
Employee who is Highly Compensated Employee under Section 8.01(i)(1)(A) or
Section 8.01(i)(1)(C), the Matching Contributions, Voluntary Participant
Contributions and Statutory Compensation of such a Highly Compensated Employee
shall include the Matching Contributions, Voluntary Contributions, and Statutory
Compensation of family members (as defined in Section 8.01(i)(6)), and such
family members shall be disregarded in determining the Average Contribution
Percentage for Employees who are Nonhighly Compensated Employees.

          (e)  In the event that the Average Contribution Percentage for
Employees who are Highly Compensated Employees exceeds the amount permissible
under Subsection (a) hereof, then, prior to the closing of the following Plan
Year, such excess amounts (and to the extent required any income allocable
thereto) shall, in accordance with procedures to be developed by the Plan
Administrator and consistent with the requirements of sections 401(m)(b) of the
Code, be distributed to the appropriate Participants, notwithstanding any other
provision herein.

any Employee shall satisfy such other requirements as may be prescribed by the
Secretary of the Treasury.

sum of the Average Actual Deferral Percentages and the Average Contribution
Percentage for all Participants who are Highly Compensated Employees shall not
exceed the sum of (a) and (b) where:

          (a)  is the product of 1.25 and the greater of (1) the Average Actual
Deferral Percentage for all Participants who are Non-Highly Compensated
Employees; or (2) the Average Contribution Percentage for all Participants who
are Non-Highly Compensated Employees; and

          (b)  is the product of 2.0 and the lesser of (1) or (2) above;
provided, however, that in no event shall this amount exceed the lesser of (1)
or (2) above by more than two percentage points.

     If the limitation in this Section is not met, the Average Actual Deferral
Percentage or the Average Contribution Percentage of Highly Compensated
Employees, as determined by the Committee, shall be reduced until such
limitation is met.

          (b)  Change of Election.  A Participant may change his investment

     Sec. 9.04  Individual Accounts.  There shall be maintained on the books of

Account.  As of April 1, 1993 the ESOP potion of the Plan shall be terminated.

     Sec. 9.05  Valuations.  The Trust Fund shall be valued by the Trustee, or
                ----------                                                    
such other person or person as the Trustee may select, at fair market value as

     Sec. 9.06  Adjustment of Individual Accounts.  The Accounts of each
                ---------------------------------                       
Participant shall be adjusted as of each Valuation Date by first (i) reducing
such Accounts by any payments made therefrom since the preceding Valuation Date,
and then (ii) increasing or reducing such Account by the Participant's allocable
share of the net amount of income, gains and losses (realized and unrealized)
and expenses of such applicable Investment Fund since the preceding Valuation
Date, and lastly (iii) crediting such Accounts with any contributions made
thereto since the preceding Valuation Date.

     Sec. 9.07  Accounts Pending Distribution.  Unless the Plan Administrator
                -----------------------------                                
expressly provides for the crediting of investment results up to the Benefit
Commencement Date (and then only if practicable under any investment contract or
other relevant funding vehicle where a distribution is to be made as of a
particular Valuation Date), there shall be no adjustment in the amount to be
distributed by reason of the passage of time or investment experience of the
Participants' Accounts between the Valuation Date as of which the amount of such
distribution is determined and the Benefit Commencement Date.  Therefore, the
balance in the Account of any Participant ordinarily shall not be adjusted to
reflect interest, dividends, investment gains or

                -------------------------------------------                  
maintained hereunder for a Participant shall be treated for all Plan purposes,
including investment direction, vesting and distribution rights, the same as a
Voluntary Participant Contribution Account.  Any ESOP Account maintained
hereunder for a Participant shall be treated for all Plan purposes, other than
investment direction, but including vesting and distribution rights, the same as
a Profit-Sharing Account. Any ESOP account shall be invested entirely 100% in
the Common Stock Fund.

     Sec. 9.09  Special ESOP Distribution and Payment Requirements.
                --------------------------------------------------

otherwise available under the Plan.

     (b)  Time of Distribution.  Notwithstanding any other provision of the
          --------------------                                             
Plan, other than such provisions as require the consent of the Participant and
the Participant's Spouse to a distribution with a present value in excess of
$3,500, a Participant may elect to have the portion of the Participant's ESOP
Account attributable to Employer Securities acquired by the Plan after December
31, 1986, distributed as follows:

          (1)  If the Participant separates from service by reason of the
     attainment of Normal Retirement Age, death, or disability, the distribution
     of such portion of the Participant's account balance will begin not later
     than one year after the close of the Plan Year in which such event occurs
     unless the Participant otherwise elects under the provisions of the Plan
     other than this Section 9.09.

          (2)  If the Participant separates from service for any reason other
     than those enumerated in paragraph (i) above, and is not reemployed by the
     Employer at the end of the fifth Plan Year following the Plan Year of such

                                                       -------------------------

          (3)  If the Participant separates from service for a reason other than
     those described in paragraph (i) above, and is employed by the Employer as
     of the last day of the fifth Plan Year following the Plan Year of such
     separation from service, distribution to the Participant, prior to any
     subsequent separation from service, shall be in accordance with terms of
     the Plan other than this Section 9.09.

This Section 9.09 shall not apply to any Company Stock held in the ESOP Account
acquired with the proceeds of a loan described in section 404(a)(9) of the Code

shall be made in substantially equal annual payments over a period of five years
unless the Participant otherwise elects under provisions of the Plan other than
this Section 9.09. In no event shall such distribution period exceed the period
permitted under section 401(a)(9) of the Code.

     (d)  Determination of Amount Subject to Special Distribution and Payment
          -------------------------------------------------------------------
Requirements.  The portion of a Participant's ESOP Account balance attributable

to Employer Securities which was acquired by the Plan after December 31, 1986,
shall be determined by multiplying the number of shares of such stock held in
the account by a fraction, the numerator of which is the number of shares
acquired by the Plan after December 31, 1986, and allocated to Participants'
ESOP Account (not to exceed the number of shares held by the Plan on the date of
distribution) and the denominator of which is the total number of such shares
held, in the Participant's ESOP Account at the date of the distribution.
 
     9.10  Put Option Requirements
           -----------------------

          (a)  In General.  This Section 9.10 shall apply to distributions of

Participant with a put option that complies with the requirements of section
409(h) of the Code.  Such put option shall provide that if a Participant
exercises the put option, the Employer, or

                                                       -------------------------

the Plan if the Plan so elects, shall repurchase such stock as follows:

               (1)  If the distribution constitutes a total distribution within
     the meaning of section 409(h)(5) of the Code, payment of the fair market
     value of a Participant's ESOP Account balance shall be made in five
     substantially equal annual payments.  The first installment shall be paid
     not later than 30 days after the Participant exercises the put option.  The
     Plan will pay a reasonable rate of interest and provide adequate security
     on amounts not paid after 30 days.

               (2)  If the distribution does not constitute a total distribution
     (as defined in (i) above), the Plan shall pay the Participant an amount
     equal to the fair market value of the Company Stock repurchased no later
     than 30 days after the Participant exercises the put option.

     9.11  Diversification of Investments
           ------------------------------

          (a)  Election By Qualified Participant.  Each Qualified Participant
               ---------------------------------

value of the Participant's account balance attributable to Company Stock held in
the ESOP Account which was acquired by the Plan after December 31, 1986, within

Election Period.  Within 90 days after the close of the last Plan Year in the
Participant's Qualified Election Period, a Qualified Participant may direct the
Plan as to the investment of 50 percent of the value of such account balance.

          (b)  Method of Directing Investment.  The Participant's direction
               ------------------------------                              
shall be provided to the Plan Administrator in writing; shall be effective no
later than 180 days after the close of the Plan Year to which the direction

          (c)  Investment Options.
               ------------------ 

               (1)  At the election of the Qualified Participant, the Plan shall
     distribute (notwithstanding section 409(d) of the Code) the portion of the

     Plan concerning put options as would otherwise apply to a distribution of
     Company Stock held in the ESOP Account from the Plan. This Section 9.11(c)
     shall apply notwithstanding any other provision of the Plan other than such
     provisions as require the consent of the Participant and the Participant's
     Spouse to a distribution with a present value in excess of $3,500. If the
     Participant and the Participant's Spouse do not consent, such amount shall
     be retained in this Plan.

               (2)  In lieu of distribution under Section 9.11, the Qualified
     Participant who has the right to receive a cash distribution under Section
     9.11 may direct the Plan to transfer the portion of the Participant's
     Account that is covered by the election to another qualified plan of the
     Employer which accepts such transfers, provided that such plan permits
     employee-directed investment and does not invest in Employer stock to a
     substantial degree.  Such transfer shall be made no later than ninety days
     after the last day of the period during which the election can be made.

               (3)  If the Plan is a TCESOP, any distribution or transfer under
     this Section 9.11(c) shall be made first from Employer Securities allocated
     to the Participant's account at least 84 months before the month in which
     the distribution or transfer occurs.

          (d)  Determination of Amount Subject to Diversification Requirements.
               ---------------------------------------------------------------  
The portion of a Participant's ESOP Account attributable to Company Stock which
was acquired by the Plan after December 31, 1986, shall be determined by
multiplying the number of shares of such stock held in the account by a
fraction, the numerator of which is the number of shares acquired by the Plan
after December 31, 1986, and allocated to Participants' ESOP Account (not to
exceed the number of shares held in the ESOP Account on the date the individual
becomes a Qualified Participant) and the denominator of which is the total
number of shares held by the Plan at the date the individual becomes a Qualified
Participant.

     9.12  Voting Rights of Participants.  Notwithstanding any other provision
           -----------------------------                                      
of the Plan, if the Plan has any class of securities which is not a
registration-type class of securities (as defined in section 409(e)(4) of the
Code), a Participant shall be entitled to direct the Trustee as to the manner in
which voting rights will be exercised with respect to any corporate matter which
involves the voting of such shares allocated to the

April 1, 1993, the ESOP was terminated and the foregoing provisions shall not
apply to the extent permitted by law.

     9.16  Fiduciary Responsibility.
           ------------------------ 

          (a) Effective as of January 1, 1994, this Plan is intended to
constitute a plan described in section 404(c) of ERISA, and Title 29 of the Code
of Federal Regulations (S)2550.404c-1.  Neither the Company, an Employer, the

any losses which are the result of investment instructions provided by any
Participant, Beneficiary or Alternate Payee.

          (b) The Plan Administrator is hereby designated as the fiduciary for
ensuring that (1) procedures are maintained by the Plan to safeguard the
confidentiality of information relating to the purchase, holding, and sale of
Company Stock and the exercise of voting, tender and similar rights with respect
to Company Stock by Participants, Beneficiaries and Alternate Payees, (2)

the procedures described in (1) are sufficient to maintain confidentiality,
except to the extent necessary to comply with federal law or state laws not
preempted by ERISA, and (3) an independent fiduciary is appointed to carry out
activities relating to any situations involving a potential for undue Employer
influence upon Participants, Beneficiaries, or Alternate Payees with regard to
the direct or indirect exercise of shareholder rights.

          (a)    Voluntary Participant Contribution Account.  A Participant may
                 ------------------------------------------                    
withdraw all or a portion of the balance of his Voluntary Participant

                                                       -------------------------

as soon as practicable thereafter. Hardship withdrawals shall, to the extent the
Plan Administrator determines necessary, be made effective and paid out sooner
and shall be based on such Participant's Account balance as of the most recent
Valuation Date in such manner as the Plan Administrator shall provide.

          (b)  A Participant may make no more than one (1) withdrawals pursuant
to Section 10.05 during any Plan Year; provided that (i) any withdrawals made
pursuant to Section 10.05(c) shall not be subject to such limitation, and (ii) a
simultaneous withdrawal of amounts pursuant to the various Subsections of
Section 10.05 shall be deemed to be a single withdrawal.

          (c)  All withdrawals shall be paid in a lump-sum cash payment.

          (d)  All withdrawals shall be deemed to be made from the Investment
Funds in which the affected Accounts of the Participant are then invested as
elected by the Participant.

          (e)  Any withdrawal by a Participant who has a spouse shall require
spousal consent in the same manner as is provided in Section 10.08(c).
Effective January 1, 1994, no spousal consent shall be required for any
withdrawal by a Participant, unless the Participant has a spouse and has elected
to receive benefits in a life annuity form (as described in Section
11.02(a),(b), or (c)) upon termination of employment.  Any such spousal consent
so required shall be made in the same manner as provided in Section 10.08(c).

     Sec. 10.07  Hardship Distribution Guidelines.  The Plan Administrator shall
                 --------------------------------                               
determine whether a distribution can be made on account of the financial
hardship of a Participant based on whether there is an immediate and heavy
financial need of the Participant and whether the distribution is necessary to
satisfy such financial need.

          (a)  In general, whether a financial need of a Participant requesting
a distribution on account of financial hardship is immediate and heavy will be
determined by the Plan Administrator on the basis of all relevant facts and
circumstances.  Notwithstanding the previous sentence, the Plan Administrator
shall always determine that a distribution is on account of an immediate and
heavy financial need of a Participant when the distribution is on account of:

               (1) expenses for medical care described in section 213(d) of the
     Code incurred by the Participant, the Participant's spouse, or any
     dependents of the Participant (as defined in section 152 of the Code) or
     necessary for such individuals to obtain the medical care described in
     section 213(d) of the Code;

               (2) costs directly related to the purchase (excluding mortgage
     payments) of a principal residence for the Participant;

               (3) the payment of tuition and related educational fees for the
     next twelve (12) months of post-secondary education for the Participant,
     the Participant's spouse, the Participant's children or any dependents of
     the Participant (as defined in section 152 of the Code); or

               (4) the need to prevent the eviction of the Participant from his
     principal residence or foreclosure on the mortgage of the employee's
     principal resident.

     This listing automatically shall be expanded, without the necessity of any
     amendment of this Subsection, to include additional situations upon
     publication by the Commissioner of Internal Revenue of revenue rulings,
     notices and other documents of general applicability expanding the listing
     in Treasury Regulation section 1.401(k)-1(d)(2)(i)(B) of situations deemed
     to be on account of immediate and heavy financial needs.

          (b)  In general, whether a distribution is necessary to satisfy the
financial need of a Participant will be determined by the Plan Administrator on
the basis of all relevant facts and circumstances.  However, the financial need
for which the Participant is requesting a distribution could not reasonably be
relieved through reimbursement or other compensation by insurance, reasonable
liquidation of the employee's assets, cessation of Salary Deferral Contributions
or Voluntary Participant Contributions, other distributions from the Plan or
other plans maintained by the Employer or any other employer or by borrowing
from other commercial sources on reasonable commercial grounds in an amount
sufficient to satisfy the need. A Participant's resources shall also include the
resources of the Participant's spouse and minor children, to the extent that
these resources are reasonably available to the Participant. Notwithstanding the
preceding three sentences, the Plan Administrator shall always determine that a
distribution is

necessary to satisfy an immediate and heavy financial need of a Participant when
all of the following requirements are satisfied:

               (1)  the distribution is not in excess of the amount of the
     immediate and heavy financial need of the Participant;

               (2)  the Participant has obtained all distributions, other than
     hardship distributions under the Plan, and all nontaxable loans currently
     available under all plans maintained by the Employer;

               (3)  the Plan and all other plans that are or may be maintained
     by the Employer provide that the Participant's elective deferral and
     employee contributions will be suspended for at least twelve (12) months
     after the receipt of the hardship distribution, after which time the
     Participant may elect to make a new Salary Deferral election which shall
     become effective as of the first payroll period ending after the Election
     Date specified in the Salary Deferral election; and

               (4)  for the taxable year immediately following the taxable year
     of the hardship distribution, the Plan and all other plans that are or may
     be maintained by the Employer provide that the Participant may not make
     salary reduction contributions in excess of the applicable limit under
     section 402(g) of the Code less the amount of the Participant's salary
     reduction contribution for the taxable year of the hardship distribution.

          (c)  The Plan Administrator, in making its determination as to whether
a Hardship Distribution shall be made, shall rely on the written representations
of the Participant, unless the Plan Administrator or the Employer has actual
knowledge to the contrary, and shall not be required to further investigate the
Participant's financial situation in order to determine whether to make the
distribution.

          (d)  Any withdrawal by a Participant who has a spouse shall require
spousal consent in the same manner as is provided in Section 10.08(c).
Effective January 1, 1994, no spousal consent shall be required for any hardship
withdrawal by a Participant, unless the Participant has a spouse and has elected
to receive benefits in a life annuity form (as described in Section
11.02(a),(b), or (c)) upon termination of employment.

becoming payable upon the Participant's death.  All Beneficiary designations
shall be in writing in form satisfactory to the Plan Administrator.  Each
Participant shall be entitled to change his Beneficiaries at any time and from
time to time.

          In the event that the Participant fails to designate a Beneficiary to
receive a benefit that becomes payable pursuant to the provisions of this
Article, or in the event that the Participant is predeceased by all designated
primary and secondary Beneficiaries, the death benefit shall be payable to the
following classes of takers, each class to take to the exclusion of all
subsequent classes, with all members of each class sharing equally:

               (1)  Spouse;

               (2)  lineal descendants (including adopted and step-children),
          per stirpes;

     public; and

     Sec. 10.09  Required Distribution Dates.  Anything contained in this
                 ---------------------------                             
Article X to the contrary notwithstanding, the Benefit Commencement Date for any
Participant shall not be later than the April 1 of the calendar year next
following the calendar year in which he attains age 70 1/2.

     Sec. 10.10  Domestic Relations Orders.
                 ------------------------- 

          (a)  Effect of Quadros.  All benefits provided under this Plan are
               -----------------                                            
subject to the provisions of any "qualified domestic relations order" within the
meaning of section 206(d)(3)(B) of ERISA (hereinafter referred to as a "Quadro")
in effect with respect to the Participant at the Participant's Benefit
Commencement Date, and are subject to diminution thereby. The person entitled to
receive payments of benefits under the Plan pursuant to a Quadro is hereinafter
referred to as an "Alternate Payee."

          (b)  Determination of Quadro Status.  Upon receipt of notification of
               ------------------------------                                  
any judgment, decree or order (including approval of a property settlement
agreement) which relates to the provision of child support, alimony payments, or
marital property rights of a spouse, former spouse, child, or other dependent of
a Participant and which is made pursuant to a state domestic relations law
(including a community property law) (herein referred to as a "domestic
relations order"), the Plan Administrator shall (a) notify the Participant and
any prospective Alternate Payee named in the order of the receipt and date of
receipt of such domestic relations order and of the Plan's procedures for
determining the status of the domestic relations order as a Quadro, and (b)
within a reasonable period after receipt of such order, determine whether it
constitutes a Quadro.

          (c)  Determination Period.  During any period in which the issue of
               --------------------                                          
whether a domestic relations order is a Quadro is being determined (by the Plan
Administrator, by a court of competent jurisdiction, or otherwise), the Plan
Administrator shall segregate in a separate account in the Plan or in an escrow
account held by a Trustee the amounts, if any which would have been payable to
the Alternate Payee during such period if the order had been determined to
constitute a Quadro, provided that,

                                                       CAPITAL ACCUMULATION PLAN
                                                       -------------------------

if no payments would otherwise be made under the Plan to the Alternate Payee or
to the Participant or a Beneficiary of the Participant while the status of the
order as a Quadro is being determined, no segregation into a separate or escrow
account shall be required. If a domestic relations order is determined to be a
Quadro within eighteen (18) months of the date of its receipt by the Plan
Administrator (or from the beginning of any other period during which the issue
of its being a Quadro is being determined by the Plan Administrator), the Plan
Administrator shall cause to be paid to the persons entitled thereto the
amounts, if any, held in the separate or escrow account referred to above. If a
domestic relations order is determined not to be a Quadro, or if the status of
the domestic relations order as a Quadro is not finally resolved within such
eighteen (18) month period, the Plan Administrator shall cause the separate or
escrow account balance, with interest thereon, to be returned to the
Participant's credit, or to be paid to the person or persons to whom such amount
would have been paid if there had been no such domestic relations order,
whichever is appropriate. Any subsequent determination that such domestic
relations order is a Quadro shall be prospective in effect only.

          (d)  Provisions Relating to Alternate Payees.
               --------------------------------------- 

               (1)  Benefits payable to an Alternate Payee shall not continue
     beyond the lifetime of the Alternate Payee.  In particular, no Alternate
     Payee shall have the right with respect to any benefit payable by reason of
     a Quadro to (A) designate a Beneficiary with respect to amounts becoming
     payable under the Plan, (B) elect a method of benefit distribution
     providing for benefits continuing beyond the Alternate Payee's lifetime,
     (C) provide survivorship benefits to a spouse or dependent of such
     Alternate Payee or to any other person, spouse, dependent or other person,
     or (D) transfer rights under the Quadro by will or by state law of
     intestacy.

               (2)  None of the payments, benefits or rights of any Alternate
     Payee shall be subject to any claim of any creditor, and, in particular, to
     the fullest extent permitted by law, all such payments, benefits and rights
     shall be free from attachment, garnishment, trustee's process, or any other
     legal or equitable process available to any creditor of such Alternate
     Payee.  No Alternate Payee shall have the right to alienate, anticipate,
     commute, pledge, encumber or assign any of the benefits or payments which
     he may

     expect to receive, contingently or otherwise, under the Plan.

               (3)  Alternate Payees shall not have any right to (A) borrow
     money under any Participant loan provisions under the Plan, (B) exercise
     any Participant investment direction rights or privileges under the Plan,
     (C) exercise any other election, privilege, option or direction rights of
     the Participant under the Plan except as specifically provided in the
     Quadro, or (D) receive communications with respect to the Plan except as
     specifically provided by law, regulation or the Quadro.

               (4)  Each Alternate Payee shall advise the Plan Administrator in
     writing of each change or his name, address or marital status, and of each
     change in the provisions of the Quadro or of any circumstance set forth
     therein which may be material to the Alternate Payee's entitlement to
     benefits thereunder or the amount thereof.  Until such written notice has
     been provided to the Plan Administrator, the Plan Administrator shall be
     (i) fully protected in not complying with, and in conducting the affairs of
     the Plan in a manner inconsistent with, the information set forth in
     notice, and (ii) required to act with respect to such notice prospectively
     only, and then only to the extent provided for in the Quadro.  The Plan
     Administrator shall not be required to modify or reverse any payment,
     transaction or application of funds occurring before the receipt of any
     notice that would have affected such payment, transaction or application of
     funds, nor shall the Plan Administrator or any other party be liable for
     any such payment, transaction or application of funds.

               (5)  Except as specifically provided for in the Quadro, an
     Alternate Payee shall have no right to interfere with the exercise by the
     Participant or by any Beneficiary of their respective rights, privileges
     and obligations under the Plan.

          (b)  A single life annuity provided for by the application of a

thirty (30) days and no more than ninety (90) days prior to the distribution or
direct rollover of an eligible rollover distribution, the Plan Administrator
shall provide the individual entitled to the distribution with a written

parties in interest, as that term is defined in section 3(14) of ERISA shall be
allowed if, and only if, the Participant from whose account the loan is

     Sec. 12.02  Loans as Trust Fund Investments.  All loans shall be considered
                 -------------------------------                                
as investments in the Investment Funds of the Trust Fund, on a pro rata basis.
Accordingly, the following conditions shall prevail with respect to each such
loan:

          (a)  Security.  All loans shall be secured by the pledge of the
               --------

Effective as of April 1, 1993, all loans shall be secured by the pledge of 50%
of the Participant's or Beneficiary's entire vested interest in the Trust Fund.

          (b)  Interest Rate.  Interest shall be charged at a rate to be fixed
               -------------                                                  
by the Plan Administrator and, in determining the interest rate, the Plan
Administrator shall take into consideration interest rates currently being
charged on similar commercial loans by persons in the business of lending money.
Interest shall be credited to the Investment Funds in the same manner as the
Participant directs for his current Plan Contributions.

          (c)  Loan Term.  Loans shall be for terms not less than one (1) year
               ---------

outstanding loan or loans may be deducted from any benefit which is or becomes
payable to the borrower or to his Beneficiary.  Any borrower, by taking a loan
under the Plan, consents to the deduction of any amount in default from any
remuneration due him or her by the Company or an Affiliated Company after the
occurrence of such default.

          (e)  Loan Statement.  Every Participant or Beneficiary receiving a

made, would constitute a prohibited transaction (within the meaning of section
406 of ERISA or

               ---------------                                             
shall require spousal consent in the same manner as is provided in Section
10.08(c).  Effective January 1, 1994, no spousal consent shall be required for
any loan to a Participant, unless the Participant has a spouse and has elected
to receive benefits in a life annuity form (as described in Section
11.02(a),(b), or (c)) upon termination of employment.  Any such spousal consent
so required shall be made in the same manner as provided in Section 10.08(c).

          (i)  Loan Fees.  Effective as of April 1, 1993, fees properly
               ---------

               (2)  Each Non-key Employee who is a Participant and who
     is covered under a qualified defined benefit plan sponsored by
     the Employer or an Affiliated Company (treating all such plans as
     a single plan) is entitled to (A) a minimum benefit accrual under
     such plan satisfying the requirements of section 416(c)(1) of the
     Code, but with "3 percent" substituted for "2 percent" and "30
     percent" substituted for "20 percent" at section 416(c)(1)(B), or
     (B) a minimum share of the Employer contribution allocation
     (including forfeiture reallocations, if any) under the Plan of
     seven and one-half percent (7-1/2%) of Statutory Compensation
     (treating the Participant's allocation under the Plan and all
     other defined contribution plans sponsored by the Employer or by
     an Affiliated Company as allocations under the Plan), or (C) and
     combination of defined benefit plan accruals as described in (A)
     hereof and defined contribution plan allocations as described in
     (B) hereof which, taken together, satisfy the requirements of
     this paragraph (2).

     Sec. 13.05  Top-Heavy Plan Minimum Allocation.  The allocation made under
                 ---------------------------------                            
Section 6.03 of the Plan to the Account of each Active Participant who is a Non-
key Employee for any Plan Year including a Plan Year in which the Plan is a Top-
Heavy Plan or a Super Top-Heavy Plan shall be not less than the lesser of:

          (a)  Three percent (3%) of the "compensation" (as defined in section
415 of the Code, but limited to the extent required under section 401(a)(17) of
the Code) of each such Participant for such Plan Year; or

          (b)  The percentage of compensation so allocated under said Section
6.03 to the Account of the Key Employee for whom such percentage is the highest
for such Accrual Plan Year.

If any person who is an Active Participant in the Plan is a Participant under
any defined benefit pension plan qualified under section 401(a) of the Code
sponsored by the Employer or an Affiliated Company, there shall be substituted
"Four percent (4%)" for "Three percent (3%)" in Subsection (a) of this Section.
For the purposes of determining whether or not the provisions of this Section
have been satisfied, (i) contributions or benefits under chapter 2 of the Code
(relating to tax on self-employment income), chapter 21 of the Code (relating to
Federal Insurance Contributions Act), title II of the Social Security Act, or
any other Federal or state law are disregarded; (ii) employer

contributions made to the Plan under any Deferral Agreement shall be
disregarded; and (iii) all defined contribution plans in the Aggregation Group
shall be treated as a single plan. For the purposes of determining whether or
not the requirements of this Section have been satisfied, contributions
allocable to the account of the Participant under any other qualified defined
contribution plan that is part of the Aggregation Group shall be deemed to be
contributions made under the Plan, and, to the extent thereof, no duplication of
such contributions shall be required hereunder solely by reason of this Section.
This Section shall not apply in any Accrual Plan Year in which the Plan is part
of an Aggregation Group containing a defined benefit pension plan (or a
combination of such defined benefit pension plans) if the Plan enables a defined
benefit pension plan required to be included in such Aggregation Group to
satisfy the requirements of either section 401(a)(4) or section 410 of the Code.

          (b)  Effect on Retired Persons, Etc. Termination of the Plan shall
               -------------------------------                              
have no effect upon payment of installments and benefits to former Participants,
their Beneficiaries and their estates, whose benefit payments commenced prior to
Plan termination.  The Trustee shall retain sufficient assets to complete any
such payments, and shall have the right, upon direction by the Company, to
purchase annuity contracts to assure the completion of such payments or to pay
the value of the remaining payments in a lump-sum distribution.

          (c)  Effect on Remaining Participants.  The Company shall instruct the
               --------------------------------                                 
Trustee either (1) to continue to manage and administer the assets of the Trust
for the benefit of the Participants and their beneficiaries pursuant to the
terms and provisions of the Trust Agreement, or (2) to pay over to each
Participant (and former Participant) the value of his vested interest, and to
thereupon dissolve the Trust Fund.

     Sec. 17.03 Complete Discontinuance of Contributions.  While it is the
                ----------------------------------------                  
Employer's intention to make substantial and recurrent contributions to the
Trust Fund pursuant to the provisions of one or more of Sections 4.01 of the
Plan, the right is, nevertheless, reserved to at any time completely discontinue
such Employer contributions.  Such complete discontinuance shall be established
by resolution of the Board of Directors and shall have the effect of a
termination of the Plan, as set forth in Section 17.02, except that the Trustee
shall not have the authority to dissolve the Fund except upon (a) adoption of a
further resolution by the Company to the effect that the Plan is terminated and
upon receipt from the Company of instructions to dissolve the Fund pursuant to
Section 17.02(c) hereof.  No such instruction shall be issued if the effect
thereof is a violation of section 401(k) of the Code.

     Sec. 17.04  Suspension of Contributions.  The Employers shall have the
                 ---------------------------                               
right at any time, and from time to time, to suspend Employer contributions to
the Fund pursuant to the Plan. Such suspension shall have no effect on the
operation of the Plan except as set forth below:

          (a)  If the Employer determines by resolution that such suspension
shall be permanent, a permanent discontinuance of contributions will be deemed
to have occurred as of the date of such resolution or such earlier date as is
therein specified.

          (b)  If such suspension becomes a plan termination, a complete
discontinuance of contributions will be imputed.  In such case, the permanent
discontinuance, with resultant full

earlier of:

               (1)  the date specified by resolution of the Employer or
     established as a matter of equity by the Plan Administrator, or

               (2)  the last day of the first Plan Year which meets both of the
     following criteria: (A) no Employer contributions were made for that, or
     for any subsequent Plan Year, and (B) there existed for such Considered Net
     Profits out of which the Employer contributions could have been made.

     Sec. 17.05  Mergers and Consolidations of Plans.  In the event of any
                 -----------------------------------                      
merger or consolidation with, or transfer of assets or liabilities to, any other
plan, each Participant shall have a normal retirement benefit in the surviving
or transferee plan (determined as if such plan were then terminated immediately
after such merger, consolidation or transfer) that is equal to or greater than
the normal retirement benefit he would have been entitled to receive immediately
before such merger, consolidation or transfer in the Plan in which he was then a
Participant (had such Plan been terminated at that time).  For the purposes
hereof, former Participants and Beneficiaries shall be considered Participants.

an order of a court of competent jurisdiction to the contrary, none of the
payments, benefits or rights of any Participant, Beneficiary or Alternate Payee
shall be subject to any claim of any creditor, and, in particular, to the

free from attachment, garnishment, trustee's process, or any other legal or
equitable process available to any creditor of such Participant, Beneficiary, or
Alternate Payee.  Except as provided in Section 18.01(b), no Participant,
Beneficiary or Alternate Payee shall have the right to alienate, anticipate,
commute, pledge, encumber or assign any of the benefits or payments which he

which pledge shall give the Trustee a first lien in such interest to the extent

Participant or Employee, or any person whomsoever, the right to be retained in
the service of the Company or any Affiliated Company, and all Participants and
other Employees shall remain subject to discharge to the same extent as if the
Plan had never been adopted.

                   SEI CORPORATION CAPITAL ACCUMULATION PLAN

          WHEREAS, SEI Corporation (the "Company") maintains the SEI Corporation
Capital Accumulation Plan (the "Plan") for the benefit of its eligible
employees;

          WHEREAS, effective January 1, 1992, the definition of "Employee"
provided in Section 2.14 of the Plan was revised to exclude from such definition
wholesale, retail and franchise sales personnel connected with a single bank or
other financial institution;

          WHEREAS, it was the Company's intention to exclude from the definition
of "Employee" provided in Section 2.14 of the Plan and in practice the Company
has excluded, only retail sales personnel connected with a single bank or other
financial institution;

          WHEREAS, the Company now wishes to make a corrective amendment to the
Plan so as to have the terms properly reflect the Company's intent in this

     from coverage under the Plan by the terms of any Adoption Agreement, (ii)
     any person whose terms and conditions of employment are determined through

     to participate in this Plan, (iii) any person who, as to the United States,
     is a non-resident alien with no U.S. source income from the Employer, and

                               AMENDMENT 1995-2
                                    TO THE
                   SEI CORPORATION CAPITAL ACCUMULATION PLAN


          WHEREAS, SEI Corporation (the "Company") maintains the SEI Corporation
Capital Accumulation Plan (the "Plan") for the benefit of its eligible
employees; and

          WHEREAS, the Company desires to makes certain changes to the Plan
requested by the Internal Revenue Service as a condition of the issuance of a
favorable determination letter on the Plan's qualification and certain other
similar changes.

          NOW, THEREFORE, in accordance with the foregoing, the Plan shall be
amended, effective as of January 1, 1992, as follows:

          1.   Section 7.05(b) of the Plan shall be amended to read, in its
entirety, as follows:

               "(b) Reduction in Excess Amounts.  All amounts withheld pursuant
                    ---------------------------                           
          to a Salary Deferral election and thereafter delivered to the Trustee
          shall be so delivered only if the Employer in good faith believes that
          such amounts do not exceed the amounts permissible pursuant to the
          limitations set forth in Section 8.03(a). If any amount shall be
          withheld from the Compensation of a Participant pursuant to a Salary
          Deferral election which exceeds the maximum amount permissible
          pursuant to Section 8.03(a) for any Plan Year, then, prior to the
          close of the following Plan Year, such excess amounts (and to the
          extent required any income allocable thereto), as determined below,
          shall, in accordance with procedures to be developed by the Plan
          Administrator, which procedures shall be consistent with the
          requirements of section 401(k)(8) of the Code, either be distributed
          to the appropriate Active Participants or, at the election of such
          Participants, be treated as having been distributed and recontributed
          to the Plan. Such distribution or distribution and recontribution may
          be made notwithstanding any Plan provision to the contrary. Such
          excess amounts shall be determined by reducing the Actual Deferral
          Percentage of the Highly Compensated Employee with the highest Actual
          Deferral Percentage until Subsection (a) is satisfied, or until the
          Actual Deferral Percentage of such Highly Compensated Employee is
          equal to the Actual Deferral Percentage of the Highly Compensated
          Employee with the next highest Actual Deferral Percentage. This
          process shall be repeated until Subsection (a) is satisfied. Effective
          for Plan Years beginning on or after January 1, 1993 or such later
          date as may be provided under Treasury regulations, any Matching
          Contributions that such
<PAGE>
 
          Participant has received on account of his excess Salary Deferral
          Contributions shall be forfeited and any such forfeited amounts shall
          be treated as a Matching Contribution, made pursuant to Section
          4.01(b), and reallocated, pursuant to Section 6.02, to the Matching
          Contribution Accounts of Participants who are eligible to share in
          Matching Contributions."

          2.   Section 8.04(e) of the Plan shall be amended to read, in its
entirety, as follows:

               "(e) In the event that the Average Contribution Percentage for
          Employees who are Highly Compensated Employees exceeds the amount
          permissible under Subsection (a) hereof, then, prior to the closing of
          the following Plan Year, such excess amounts (and to the extent
          required any income allocable thereto), as determined below, shall, in
          accordance with procedures to be developed by the Plan Administrator
          and consistent with the requirements of sections 401(m)(6) of the
          Code, be distributed to the appropriate Participants, notwithstanding
          any other provision herein. Such excess amounts shall be determined by
          reducing the Contribution Percentage of the Highly Compensated
          Employee with the highest Contribution Percentage until Subsection (a)
          is satisfied, or until the Contribution Percentage of such Highly
          Compensated Employee is equal to the Contribution Percentage of the
          Highly Compensated Employee with the next highest Contribution
          Percentage. This process shall be repeated until Subsection (a) is
          satisfied."
 
          IN WITNESS WHEREOF, SEI CORPORATION has caused this Amendment 1995-2
to the Plan to be duly executed this 22 day of December 1995, effective in
accordance with its terms.
