                  Fuller for Good Reason) after a written demand for substantial
                  performance is delivered to her by the Southern Board, which
                  demand specifically identifies the manner in which the
                  Southern Board believes that she has not substantially
                  performed her duties; or

                           (ii) The willful engaging by Ms. Fuller in conduct
                  that is demonstrably and materially injurious to the Company,
                  monetarily or otherwise, including, but not limited to any of

                           by the Company;

                                    (B) the willful carrying out of any activity
                           or the making of any statement which would materially
                           prejudice or impair the good name and standing of the
                           Company, Southern or any Southern Subsidiary or would
                           bring the Company, Southern or any other Southern
                           Subsidiary into contempt, ridicule or would
                           reasonably shock or offend any community in which the
                           Company, Southern or such Southern Subsidiary is
                           located;

                           intoxication or otherwise being found in possession
                           at her workplace of any prohibited drug or substance,
                           possession of which would amount to a criminal
                           offense;

                                    (D) violation of the Company's policies on
                           drug and alcohol usage, fitness for duty requirements
                           or similar policies as may exist from time to time as
                           adopted by the Company's safety officer;

                                    (E) assault or other act of violence against
                           any person during the course of employment; or

                                    (F) indictment of any felony or any
                           misdemeanor involving moral turpitude.

                  No act or failure to act by Ms. Fuller shall be deemed
         "willful" unless done, or omitted to be done, by Ms. Fuller not in good
         faith and without reasonable belief that her action or omission was in
         the best interest of the Company.

                  Notwithstanding the foregoing, Ms. Fuller shall not be deemed
         to have been terminated for Cause unless and until there shall have
         been delivered to her a copy of a resolution duly adopted by the
         affirmative vote of not less than three quarters of the entire
         membership of the Southern Board at a meeting of the Southern Board
         called and held for such purpose (after reasonable notice to Ms. Fuller
         and an opportunity for her, together with counsel, to be heard before
         the Southern Board), finding that, in the good faith opinion of the
         Southern Board, Ms. Fuller was guilty of conduct set forth above in
         clause (i) or (ii) of this Paragraph 1.(bb) and specifying the

                  (cc) "Termination Date" shall mean the date on which Ms.
         Fuller's employment with the Company is terminated; provided, however,
         that solely for purposes of Paragraph 2.(c) hereof, the Termination
         Date shall be the effective date of her retirement pursuant to the
         terms of the Pension Plan.

                  (dd) "Total Disability" shall mean Ms. Fuller's total
         disability within the meaning of the Pension Plan.

                  (ee) "Value Creation Plan" shall mean the Southern Energy
         Resources, Inc. Value Creation Plan or any replacement thereto, as such
         plans may be amended from time to time.

                  (ff) "Voting Securities" shall mean the outstanding voting
         securities of a corporation entitling the holder thereof to vote
         generally in the election of such corporation's directors.

         attached hereto as Exhibit B.

                  (hh) "Year of Service" shall mean Ms. Fuller's Months of
         Service divided by twelve (12) rounded to the nearest whole year,
         rounding up if the remaining number of months is seven (7) or greater
         and rounding down if the remaining number of months is less than seven
         (7). If Ms. Fuller has a break in her service with the Company, she
         will receive credit under this Agreement for service prior to the break
         in service only if the break in service is less than five years.

         2.       Severance Benefits.

                  (a) Eligibility. Except as otherwise provided in this
         Paragraph 2.(a), if Ms. Fuller's employment is involuntarily terminated
         by the Company at any time during the two year period following a
         Change in Control for reasons other than Cause, or if Ms. Fuller
         voluntarily terminates her employment with the Company for Good Reason
         at any time during the two year period following a Change in Control,
         Ms. Fuller shall be entitled to receive the benefits described in this
         Agreement upon the Company's receipt of an effective Waiver and
         Release. Notwithstanding anything to the contrary herein, Ms. Fuller
         shall not be eligible to receive benefits under this Agreement if Ms.
         Fuller:

                           (i) voluntarily terminates her employment with the
                  Company for other than Good Reason;

                           (ii) has her employment terminated by the Company for
                  Cause;

                           (iii) accepts the transfer of her employment to
                  Southern, any Southern Subsidiary or any employer that
                  succeeds to all or substantially all of the assets of the
                  Company, Southern or any Southern Subsidiary;

                           (iv) refuses an offer of continued employment with
                  the Company, any Southern Subsidiary, or any
                  employer that succeeds to all or substantially all of the
                  assets of the Company, Southern, or any Southern Subsidiary
                  under circumstances where such refusal would not amount to
                  Good Reason for voluntary termination of employment; or

                           (v) elects to receive the benefits of any other
                  voluntary or involuntary severance or separation program
                  maintained by the Company; provided however, that the receipt
                  of benefits under the terms of any retention plan or agreement
                  shall not be deemed to be the receipt of severance or
                  separation benefits for purposes of this Agreement.

                  (b) Severance Benefits. If Ms. Fuller meets the eligibility
         requirements of Paragraph 2.(a) hereof, she shall be entitled to a cash
         severance benefit in an amount equal to three times her Annual
         Compensation (the "Severance Amount"). If any portion of the Severance
         Amount constitutes an "excess parachute payment" (as such term is
         defined under Code Section 280G ("Excess Parachute Payment")), the
         Company shall pay to Ms. Fuller an additional amount calculated by
         determining the amount of tax under Code Section 4999 that she
         otherwise would have paid on any Excess Parachute Payment with respect
         to the Change in Control and dividing such amount by a decimal
         determined by adding the tax rate under Code Section 4999 ("Excise
         Tax"), the hospital insurance tax under Code Section 3101(b) ("HI Tax")
         and federal and state income tax measured at the highest marginal rates
         ("Income Tax") and subtracting such result from the number one (1) (the
         "280G Gross-up"); provided, however, that no 280G Gross-up shall be
         paid unless the Severance Amount plus all other "parachute payments" to
         Ms. Fuller under Code Section 280G exceeds three (3) times Ms. Fuller's
         "base amount" (as such term is defined under Code Section 280G ("Base
         Amount")) by ten percent (10%) or more; provided further, that if no
         280G Gross-up is paid, the Severance Amount shall be capped at three
         (3) times Ms. Fuller's Base Amount, less all other "parachute payments"
         (as such term is defined under Code Section 280G) received by Ms.
         Fuller, less one dollar (the "Capped Amount"), if the Capped Amount,
         reduced by HI Tax and Income Tax, exceeds what otherwise would have
         been the Severance Amount, reduced by HI Tax, Income Tax and Excise
         Tax.

                  For purposes of this Paragraph 2.(b), whether any amount would
         constitute an Excess Parachute Payment and any other calculations of
         tax, e.g., Excise Tax, HI Tax, Income Tax, etc., or other amounts,
         e.g., Base Amount, Capped Amount, etc., shall be determined by the tax
         department of the independent public accounting firm then responsible
         for preparing Southern's consolidated federal income tax return, and
         such calculations or determinations shall be binding upon the parties
         hereto.

                  (c) Welfare Benefits. If Ms. Fuller meets the eligibility
         requirements of Paragraph 2.(a) hereof and is not otherwise eligible to
         receive retiree medical and life insurance benefits provided to certain
         retirees pursuant to the terms of the Pension Plan, the Group Health
         Plan and the Group Life Insurance Plan, she shall be entitled to the
         benefits set forth in this Paragraph 2.(c).

                           (i) Ms. Fuller shall be eligible to participate in
                  the Company's Group Health Plan, upon payment of both the
                  Company's and her monthly premium under such plan, for a
                  period of six (6) months for each of Ms. Fuller's Years of
                  Service, not to exceed five (5) years. If Ms. Fuller elects to
                  receive this extended medical coverage, she shall also be
                  entitled to elect coverage under the Group Health Plan for her
                  dependents who were participating in the Group Health Plan on
                  Ms. Fuller's Termination Date (and for such other dependents
                  as may be entitled to coverage under the provisions of the
                  Health Insurance Portability and Accountability Act of 1996)
                  for the duration of Ms. Fuller's extended medical coverage
                  under this Paragraph 2.(c)(i) to the extent such dependents
                  remain eligible for dependent coverage under the terms of the
                  Group Health Plan.

                                    (A) The extended medical coverage afforded
                           to Ms. Fuller pursuant to Paragraph 2.(c)(i), as well
                           as the premiums to be paid by Ms. Fuller in
                           connection with such coverage shall be determined in
                           accordance with the terms of the Group Health Plan
                           and shall be subject to any changes in the terms and
                           conditions of the Group Health Plan as well as any
                           future increases in premiums under the Group Health
                           Plan. The premiums to be paid by Ms. Fuller in
                           connection with this extended coverage shall be due
                           on the first day of each month; provided, however,
                           that if she fails to pay her premium within thirty
                           (30) days of its due date, such extended coverage
                           shall be terminated.

                                    (B) Any Group Health Plan coverage provided
                           under Paragraph 2.(c)(i) shall be a part of and not
                           in addition to any COBRA Coverage which Ms. Fuller or
                           her dependent may elect. In the event that Ms. Fuller
                           or her dependent becomes eligible to be covered, by
                           virtue of re-employment or otherwise, by any
                           employer-sponsored group health plan or is eligible
                           for coverage under any government-sponsored health
                           plan during the above period, coverage under the
                           Company's Group Health Plan available to Ms. Fuller
                           or her dependent by virtue of the provisions of
                           Paragraph 2.(c)(i) shall terminate, except as may
                           otherwise be required by law, and shall not be
                           renewed.

                           (ii) Ms. Fuller shall be entitled to receive cash in
                  an amount equal to the Company's and Ms. Fuller's cost of
                  premiums for three (3) years of coverage under the Group
                  Health Plan and Group Life Insurance Plan in accordance with
                  the terms of such plans as of the date of the Change in
                  Control.

                  (d) Incentive Plans. If Ms. Fuller meets the eligibility
         requirements of Paragraph 2.(a) hereof she shall be
         entitled to the following benefits under the Company's incentive plans:

                           (i) Stock Option Plan.

                                    (A) Any of Ms. Fuller's Options and Stock
                           Appreciation Rights under the Performance Stock Plan
                           (the defined terms of which are incorporated in this
                           Paragraph 2.(d)(i) by reference) which are
                           outstanding as of the Termination Date and which are
                           not then exercisable and vested, shall become fully
                           exercisable and vested to the full extent of the
                           original grant; provided, that in the case of a Stock
                           Appreciation Right, if Ms. Fuller is subject to
                           Section 16(b) of the Exchange Act, such Stock
                           Appreciation Right shall not become fully vested and
                           exercisable at such time if such action would result
                           in liability to Ms. Fuller under Section 16(b) of the
                           Exchange Act, provided further, that any such actions
                           not taken as a result of the rules of Section 16(b)
                           of the Exchange Act shall be effective as of the
                           first date that such activity would no longer result
                           in liability under Section 16(b) of the Exchange Act.

                                    (B) The restrictions and deferral
                           limitations applicable to any of Ms. Fuller's
                           Restricted Stock as of the Termination Date shall
                           lapse, and such Restricted Stock shall become free of
                           all restrictions and limitations and become fully
                           vested and transferable to the full extent of the
                           original grant.

                                    (C) The restrictions and deferral
                           limitations and other conditions applicable to any
                           other Awards held by Ms. Fuller under the Performance
                           Stock Plan as of the Termination Date shall lapse,
                           and such other Awards shall become free of all
                           restrictions, limitations or conditions and become
                           fully vested and transferable to the full extent of
                           the original grant.

                           (ii) Performance Dividend Plan. Provided Ms. Fuller
                  is not entitled to benefits under the Performance Dividend
                  Plan (the defined terms of which are incorporated in this
                  Paragraph 2.(d)(ii) by reference), if the Performance Dividend
                  Plan is in place through Ms. Fuller's Termination Date and to
                  the extent Ms. Fuller is entitled to participate therein, Ms.
                  Fuller shall be entitled to receive cash for each Award held
                  by Ms. Fuller on her Termination Date, based on actual
                  performance under Section 4.1 of the Performance Dividend Plan
                  determined as of the most recently completed calendar quarter
                  of the Performance Period in which the Termination Date shall
                  have occurred, and the Annual Dividend declared prior to the
                  Termination Date.

                           (iii) Value Creation Plan. Any of Ms. Fuller's
                  Appreciation Rights or Indexed Rights under the Value Creation
                  Plan (the defined terms of which are incorporated in this
                  Paragraph 2.(d)(iii) by reference) which are outstanding as of
                  the Termination Date and which are not then exercisable and
                  vested, shall become fully exercisable and fully vested to the
                  full extent of the original grant. Notwithstanding anything in
                  the Value Creation Plan to the contrary, Share Value with
                  respect to any Appreciation Rights or Indexed Rights held by
                  Ms. Fuller following her Termination Date shall be no less
                  than the Share Value as of the date of the Change in Control
                  of Southern or the Company, as the case may be.

                           (iv) Other Short Term Incentive Plans. The provisions
                  of this Paragraph 2.(d)(i) shall apply if and to the extent
                  that Ms. Fuller is a participant in any other "short term
                  compensation plan" not otherwise previously referred to in
                  this Paragraph 2.(d). Provided Ms. Fuller is not otherwise
                  entitled to a plan payout under any change of control
                  provisions of such plans, if the "short term compensation
                  plan" is in place as of the Termination Date and to the extent
                  Ms. Fuller is entitled to participate therein, Ms. Fuller
                  shall receive cash in an amount equal to her award under the
                  Company's "short term incentive plan" for the annual
                  performance period in which the Termination Date shall have
                  occurred, at Ms. Fuller's target performance level and
                  prorated by the number of months which have passed since the
                  beginning of the annual performance period until her
                  Termination Date. For purposes of this Paragraph 2.(d)(iv) the
                  term "short term incentive compensation plan" shall mean any
                  incentive compensation plan or arrangement adopted in writing
                  by the Company which provides for annual, recurring
                  compensatory bonuses based upon articulated performance
                  criteria.

                           (v) DIC Plan. Provided Ms. Fuller is not entitled to
                  benefits under Article V of the DIC Plan (the defined terms of
                  which are incorporated into this Paragraph 2(d)(v) by
                  reference), if the DIC Plan is in place through Ms. Fuller's
                  Termination Date and to the extent that Ms. Fuller is entitled
                  to participate therein, any of Ms. Fuller's Awards as of the
                  Termination Date which are not then vested shall become fully
                  vested and Ms. Fuller shall be entitled to receive cash in the
                  amount equal to Ms. Fuller's Account as of her Termination
                  Date. Notwithstanding anything in the DIC Plan to the
                  contrary, the investment return on the Awards determined in
                  accordance with Section 3.1 of the DIC Plan for any Plan Year
                  following a Change in Control shall be no less than the
                  investment return determined in accordance with Section 3.1 of
                  the DIC Plan as of the date of such Change in Control with
                  respect to those Accounts which are outstanding as of the date
                  of such Change in Control.

                  (e) Payment of Benefits. Any amounts due under this Agreement
         shall be paid in one (1) lump sum payment as soon as administratively
         practicable following the later of: (i) Ms. Fuller's Termination Date,
         or (ii) upon Ms. Fuller's tender of an effective Waiver and Release to
         the Company in the form of Exhibit B attached hereto and the expiration
         of any applicable revocation period for such waiver. In the event of a
         dispute with respect to liability or amount of any benefit due
         hereunder, an effective Waiver and Release shall be tendered at the
         time of final resolution of any such dispute when payment is tendered
         by the Company.

                  (f) Benefits in the Event of Death. In the event of Ms.
         Fuller's death prior to the payment of all amounts due under this
         Agreement, Ms. Fuller's estate shall be entitled to receive as due any
         amounts not yet paid under this Agreement upon the tender by the
         executor or administrator of the estate of an effective Waiver and
         Release.

                  (g) Legal Fees. In the event of a dispute between Ms. Fuller
         and the Company with regard to any amounts due hereunder, if any
         material issue in such dispute is finally resolved in Ms. Fuller's
         favor, the Company shall reimburse Ms. Fuller's legal fees incurred
         with respect to all issues in such dispute in an amount not to exceed
         fifty thousand dollars ($50,000).

                  (h) Employee Outplacement Services. Ms. Fuller shall be
         eligible to participate in the Employee Outplacement Program, which
         program shall not be less than six (6) months duration measured from
         Ms. Fuller's Termination Date.

                  (i) Non-qualified Retirement and Deferred Compensation Plans.
         The Parties agree that subsequent to a Change in Control, any claims by
         Ms. Fuller for benefits under any of the Company's non-qualified
         retirement or deferred compensation plans shall be resolved through
         binding arbitration in accordance with the provisions and procedures
         set forth in Paragraph 5 hereof and if any material issue in such
         dispute is finally resolved in Ms. Fuller's favor, the Company shall
         reimburse Ms. Fuller's legal fees in the manner provided in Paragraph
         2.(g) hereof.

         3. Transfer of Employment. In the event that Ms. Fuller's employment by
the Company is terminated during the two year period following a Change in
Control and Ms. Fuller accepts employment by Southern, a Southern Subsidiary, or
any employer that succeeds to all or substantially all of the assets of the
Company, Southern or any Southern Subsidiary, the Company shall assign this
Agreement to Southern, such Southern Subsidiary, or successor employer, Southern
shall accept such assignment or cause such Southern Subsidiary or successor
employer to accept such assignment, and such assignee shall become the "Company"
for all purposes hereunder.

         4. No Mitigation. If Ms. Fuller is otherwise eligible to receive
benefits under Paragraph 2 of this Agreement, she shall have no duty or
obligation to seek other employment following her Termination Date and, except
as otherwise provided in Paragraph 2.(a)(iii) hereof, the amounts due Ms. Fuller
hereunder shall not be reduced or suspended if Ms. Fuller accepts such
subsequent employment.

         5. Arbitration.

                  (a) Any dispute, controversy or claim arising out of or
         relating to the Company's obligations to pay severance benefits under
         this Agreement, or the breach thereof, shall be settled and resolved
         solely by arbitration in accordance with the Commercial Arbitration
         Rules of the American Arbitration Association ("AAA") except as
         otherwise provided herein. The arbitration shall be the sole and
         exclusive forum for resolution of any such claim for severance benefits
         and the arbitrators' award shall be final and binding. The provisions
         of this Paragraph 5 are not intended to apply to any other disputes,
         claims or controversies arising out of or relating to Ms. Fuller's
         employment by the Company or the termination thereof.

                  (b) Arbitration shall be initiated by serving a written notice
         of demand for arbitration to Ms. Fuller, in the case of the Company, or
         to the Southern Board, in the case of Ms. Fuller.

                  (c) The arbitration shall be held in Atlanta, Georgia. The
         arbitrators shall apply the law of the State of Georgia, to the extent
         not preempted by federal law, excluding any law which would require the
         application of the law of another state.

                  (d) The parties shall appoint arbitrators within fifteen (15)
         business days following service of the demand for arbitration. The
         number of arbitrators shall be three. One arbitrator shall be appointed
         by Ms. Fuller, one arbitrator shall be appointed by the Company, and
         the two arbitrators shall appoint a third. If the arbitrators cannot
         agree on a third arbitrator within thirty (30) business days after the
         service of demand for arbitration, the third arbitrator shall be
         selected by the AAA.

                  (e) The arbitration filing fee shall be paid by Ms. Fuller.
         All other costs of arbitration shall be borne equally by Ms. Fuller and
         the Company, provided, however, that the Company shall reimburse such
         fees and costs in the event any material issue in such dispute is
         finally resolved in Ms. Fuller's favor and Ms. Fuller is reimbursed
         legal fees under Paragraph 2.(g) hereof.

                  (f) The parties agree that they will faithfully observe the
         rules that govern any arbitration between them, they will abide by and
         perform any award rendered by the arbitrators in any such arbitration,
         including any award of injunctive relief, and a judgment of a court
         having jurisdiction may be entered upon an award.

                  (g) The parties agree that nothing in this Paragraph 5 is
         intended to preclude any court having jurisdiction from issuing and
         enforcing in any lawful manner such temporary restraining orders,
         preliminary injunctions, and other interim measures of relief as may be
         necessary to prevent harm to a party's interests or as otherwise may be
         appropriate pending the conclusion of arbitration proceedings pursuant
         to this Agreement regardless of whether an arbitration proceeding under
         this Paragraph 5 has begun. The parties further agree that nothing
         herein shall prevent any court from entering and enforcing in any
         lawful manner such judgments for permanent equitable relief as may be
         necessary to prevent harm to a party's interests or as otherwise may be
         appropriate following the issuance of arbitral awards pursuant to this
         Agreement.

         6. Miscellaneous.

                  (a) Funding of Benefits. Unless the Board in its discretion
         shall determine otherwise, the benefits payable to Ms. Fuller under
         this Agreement shall not be funded in any manner and shall be paid by
         the Company out of its general assets, which assets are subject to the
         claims of the Company's creditors.

                  (b) Withholding. There shall be deducted from the payment of
         any benefit due under this Agreement the amount of any tax required by
         any governmental authority to be withheld and paid over by the Company
         to such governmental authority for the account of Ms. Fuller.

                  (c) Assignment. Ms. Fuller shall have no rights to sell,
         assign, transfer, encumber, or otherwise convey the right to receive
         the payment of any benefit due hereunder, which payment and the rights
         thereto are expressly declared to be nonassignable and nontransferable.
         Any attempt to do so shall be null and void and of no effect.

                  (d) Amendment and Termination. The Agreement may be amended or
         terminated only by a writing executed by the parties.

                  (e) Construction. This Agreement shall be construed in
         accordance with and governed by the laws of the State of Georgia, to
         the extent not preempted by federal law, disregarding any provision of
         law which would require the application of the law of another state.

                  (f) Pooling Accounting. Notwithstanding anything to the
         contrary herein, if, but for any provision of this Agreement, a Change
         in Control transaction would otherwise be accounted for as a
         pooling-of-interests under APB No.16 ("Pooling Accounting") (after
         giving effect to any and all other facts and circumstances affecting
         whether such Change in Control transaction would use Pooling
         Accounting,), such provision or provisions of this Agreement which
         would otherwise cause the Change in Control transaction to be
         ineligible for Pooling Accounting shall be void and ineffective in such
         a manner and to the extent that by eliminating such provision or
         provisions of this Agreement, Pooling Accounting would be required for
         such Change in Control transaction.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement

                           CHANGE IN CONTROL AGREEMENT

                               Waiver and Release

         I, S. Marce Fuller, understand that I am entitled to receive the
severance benefits described in Section 2 of the Change in Control Agreement
(the "Agreement") if I execute this Waiver and Release ("Waiver"). I understand
that the benefits I will receive under the Agreement are in excess of those I
would have received from The Southern Company and Southern Energy Resources,
Inc. (collectively, the "Company") if I had not elected to sign this Waiver.

         I recognize that I may have a claim against the Company under the Civil
Rights Act of 1964 and 1991, the Age Discrimination in Employment Act, the
Rehabilitation Act of 1973, the Energy Reorganization Act of 1974, as amended,
the Americans with Disabilities Act or other federal, state and local laws.

         In exchange for the benefits I elect to receive, I hereby irrevocably
waive and release all claims, of any kind whatsoever, whether known or unknown
in connection with any claim which I ever had, may have, or now have against The
Southern Company, Alabama Power Company, Georgia Power Company, Gulf Power
Company, Mississippi Power Company, Savannah Electric and Power Company,
Southern Communication Services, Inc., Southern Company Services, Inc., Southern
Energy Resources, Inc., Southern Company Energy Solutions, Inc., Southern
Nuclear Operating Company, Inc. and other direct or indirect subsidiaries of The
Southern Company and their past, present and future officers, directors,
employees, agents and attorneys. Nothing in this Waiver shall be construed to
release claims or causes of action under the Age Discrimination in Employment
Act or the Energy Reorganization Act of 1974, as amended, which arise out of
events occurring after the execution date of this Waiver.

         In further exchange for the benefits I elect to receive, I understand
and agree that I will respect the proprietary and confidential nature of any
information I have obtained in the course of my service with the Company or any
subsidiary or affiliate of The Southern Company. However, nothing in this Waiver
shall prohibit me from engaging in protected activities under applicable law or
from communicating, either voluntary or otherwise, with any governmental agency
concerning any potential violation of the law.

         In signing this Waiver, I am not releasing claims to benefits that I am
already entitled to under any workers' compensation laws or under any retirement
plan or welfare benefit plan within the meaning of the Employee Retirement
Income Security Act of 1974, as amended, which is sponsored by or adopted by the
Company and/or any of its direct or indirect subsidiaries; however, I understand
and acknowledge that nothing herein is intended to or shall be construed to
require the Company to institute or continue in effect any particular plan or
benefit sponsored by the Company and the Company hereby reserves the right to
amend or terminate any of its benefit programs at any time in accordance with
the procedures set forth in such plans.

         In signing this Waiver, I realize that I am waiving and releasing,
among other things, any claims to benefits under any and all bonus, severance,
workforce reduction, early retirement, outplacement, or any other similar type
plan sponsored by the Company.

         I have been encouraged and advised in writing to seek advice from
anyone of my choosing regarding this Waiver, including my attorney, and my
accountant or tax advisor. Prior to signing this Waiver, I have been given the
opportunity and sufficient time to seek such advice, and I fully understand the
meaning and contents of this Waiver.

         I understand that I may take up to twenty-one (21) calendar days to
consider whether or not I desire to enter this Waiver. I was not coerced,
threatened or otherwise forced to sign this Waiver. I have made my choice to
sign this Waiver voluntarily and of my own free will.

         I understand that I may revoke this Waiver at any time during the seven
(7) calendar day period after I sign and deliver this Waiver to the Company. If
I revoke this Waiver, I must do so in writing delivered to the Company. I
understand that this Waiver is not effective until the expiration of this seven
(7) calendar day revocation period. I understand that upon the expiration of
such seven (7) calendar day revocation period this entire Waiver will be binding
upon me and will be irrevocable.

         I understand that by signing this Waiver I am giving up rights I may
have.

         IN WITNESS WHEREOF, the undersigned hereby executes this Waiver this
____ day of ____________________, in the year _____.
