                               PHANTOM EQUITY PLAN
                           (Effective January 1, 2000)

                                    SECTION 1
                                  INTRODUCTION

        1.1     Establishment. Whiting Petroleum Corporation (as defined in
subsection 2.1(i), the "Company") hereby adopts the Whiting Petroleum
Corporation Equity Plan (the "Plan"). The Plan permits the grant of Phantom
Shares (as defined in subsection 2.1(t)) to employees of the Company.

        1.2     Purposes. The purposes of the Plan are to provide the employees
selected for participation in the Plan with added incentives to continue in the
service of the Company and to create in such employees a more direct interest in
the future success of the operations of the Company by relating incentive
compensation to the achievement of long-term growth and financial performance.
The Plan is also designed to attract employees and to retain and motivate
employees by providing an opportunity to participate in the long-term growth,
profitability and performance of the Company, thus enhancing the value of the
Company.

        1.3     General Plan Description. Participants in the Plan will receive
Phantom Shares (as defined herein) in the Company. The Phantom Shares will
entitle the holders to a portion of the gain in economic value of the Company,
if any, upon a Triggering Event (as defined herein) as described in Section 8.
Except as otherwise provided in Sections 8.3 and 8.4, the Phantom Shares will
not, however, entitle the holders to acquire actual securities of the Company,
nor shall the holders of the Phantom Shares have actual ownership rights, such
as voting rights, in the Company.

                                    SECTION 2
                                   DEFINITIONS

        2.1     Definitions. The following terms shall have the meanings set
forth below:

                (a)     "Affiliated Corporation" means any corporation which is
affiliated with the Company through stock ownership or otherwise and is treated
as a common employer under the provisions of Sections 414(b) and (c) of the
Internal Revenue Code.

                (b)     "Agreement" or "Plan Agreement" means the written
agreement entered into between the Company and the Participant to carry out the
provisions of the Plan with respect to the Participant and in accordance with
the Plan's terms and conditions.

                (c)     "Award Value" or "Total Award Value" means such
percentage of not less than four percent (4%) nor more than seven percent (7%),
as determined by the Board, in its sole discretion, of the positive amount
resulting from the subtraction of the Beginning Company Value from the Ending
Company Value with respect to a Performance Cycle. If there is an existing
public market for the Company's common stock, the Award Value will be paid in
stock. If the Company is preparing for a common stock public offering ("Initial
Public Offering")

<PAGE>

within 120 days or less the Award Value will be paid in common stock at the date
of its issuance. If paid in stock, the amount of stock (percentage of the
company) paid out, which shall be the percentage of outstanding common stock
paid out under the Plan measured immediately after the payout of such stock, is
calculated as AV/EV. The calculation of Award Value will be as described above
in this Section 2.1(c) and as shown below. The following example assumes that
the Board has selected five percent (5%) as the applicable percentage to
determine Award Value.

                CALCULATION OF AWARD VALUE
                --------------------------
                Award Value (AV) = (EV less BV X 5%)

                Where:

                BV = Beginning Company Value
                EV  = Ending Company Value
                   For example, if:
                EV = $890 million
                BV = $190 million
                AV = $35.0 million ($890 million less $190 million X 5%)

                If paid in stock, the percentage of the Company stock paid out
                will be calculated as follows:

                AV/EV = 3.9% of the Company ($35 million/$890 million)

                (d)     "Award" means the Award Value amount payable to the
Participant in accordance with the terms and provisions of the Plan.

                (e)     "Beginning Company Value" means $190 million which was
the Company Corporate Consolidated SEC PV10% value at January 1, 2000.

                (f)     "Board" means the Board of Directors of the Company.

                (g)     "Cause" means willful misconduct, a willful failure to
perform the Eligible Employee's duties, insubordination, theft, dishonesty,
conviction of a felony or any other willful conduct that is materially
detrimental to the Eligible Employee's performance of his or her duties or is
materially detrimental to the Company or an Affiliated Corporation or such other
cause as the Board in good faith reasonably determines provides cause for the
discharge of an Eligible Employee.

                (h)     "Change of Control" shall be deemed to have occurred if
either (A) any individual, entity, or group (within the meaning of Section
13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act")), acquires beneficial ownership (within the meaning of Rule
13d-3 promulgated under the Exchange Act), directly or indirectly, of twenty
percent (20%) or more of either (i) the then-outstanding shares of common stock
of the Company, Alliant Energy Corporation ("Alliant Energy") or Alliant Energy
Resources, Inc. ("Alliant Resources") ("Outstanding Shares") or (ii) the
combined voting power of the then-outstanding voting securities of the Company,
Alliant Energy or Alliant Resources entitled to vote generally in the election
of directors ("Voting Power").

                                      - 2 -

<PAGE>

                (i)     "Company" means Whiting Petroleum Corporation, a
Delaware corporation, or any company which is a successor thereto as a result of
merger, consolidation, liquidation or other reorganization.

                (j)     "Corporate Consolidated SEC PV10% Value" means the total
proved reserve value at PV10% using constant year-end prices and costs. If the
end of the Measuring Period is not at a year-end, constant prices and costs at
the end of the Measuring Period will be used to calculate the Ending Company
Value.

                (k)     "Effective Date" means the effective date of the Plan,
January 1, 2000.

                (l)     "Eligible Employees" means those employees (including,
without limitation, officers and directors who are also employees) of the
Company or an Affiliated Corporation who are designated for participation in the
Plan pursuant to Section 4.

                (m)     "Ending Company Value" means the Company Corporate
Consolidated SEC PV10% value at the end of the Measuring Period, less the amount
of all "Payable to Parent Debt" on the Company's balance sheet resulting from
the period June 1, 2000 to the end of the Measuring Period (the "PPD"). The June
1, 2000 date reflects the commencement of the Company's parent's plan to
increase the size of the Company. In calculating the PPD the amount of Payable
to Parent Debt will be reduced by $106 million, which was the amount of debt on
the Company's balance sheet at June 1, 2000 after equity in the Company was
converted to debt by its parent. If the Company's common stock is traded on an
established securities market as of the time Ending Company Value is determined,
the Award Value shall be paid in shares of common stock. The number of shares
paid out will be determined by the percentage of stock derived in the Award
Value calculation, as provided in Section 2.1(c).

                (n)     "Internal Revenue Code" means the Internal Revenue Code
of 1986, as it may be amended from time to time.

                (o)     "Market Value" means the average of the mean between the
bid and the asked prices of the Company's equity security(ies), or the closing
price, as applicable, on the principal stock exchange, NASDAQ, or other market
on which such equity security is traded, over the 20 consecutive trading days
ending on the date of the Triggering Event.

                (p)     "Measuring Period" means the time period between the
date as of which Beginning Company Value is determined with respect to the grant
of a Phantom Share to a Participant and the date as of which Ending Company
Value is determined, which shall be the earlier of the date of a Triggering
Event or the end of the applicable Performance Cycle.

                (q)     "Participant" means an Eligible Employee who has been
selected for participation under the Plan pursuant to Section 4, who has
executed a Plan Agreement and who has outstanding grants of Phantom Shares under
the Plan.

                (r)     "Performance Cycle" means the period established by the
Board at the time of each grant of Phantom shares at the end of which Ending
Company Value is determined (unless a Triggering Event has occurred prior to the
end of the Performance Cycle) for purposes of calculating the value of such
Phantom Shares under the Plan. The Performance Cycle with

                                      - 3 -

<PAGE>

respect to each grant of Phantom Shares shall be determined by the Board at the
time of grant and shall be specified in the Plan Agreement with respect to such
grant of Phantom Shares.

                (s)     "Permanent Disability" means any physical or mental
condition which permanently prevents a Participant from performing the material
duties of his or her current employment. If a Participant makes application for
disability benefits under the Company's long-term disability program, as now in

shall be presumed to qualify as permanently disabled under this Plan.

                (t)     "Phantom Share" means a unit of value determined under
the provisions of Section 8 of the Plan.

                (u)     "Phantom Equity Committee (PEC)" means the Committee
established to administer the Plan pursuant to Section 3.1 herein and determine
the amount of Phantom Shares to be awarded to each Plan Participant.

                (v)     "Plan" means the Whiting Petroleum Corporation Phantom
Equity Plan as set forth in this document.

                (w)     "Retirement" means termination of employment with the
Company and all Affiliated Corporations on or after reaching the normal
retirement age of sixty-five, or other retirement age agreed to by the Eligible
Employee and the Company.

                (x)     "Termination Date" means the date of a Participant's
severance from employment with the Company and all Affiliated Corporations for
any reason, including but not limited to, death, Permanent Disability,
Retirement, resignation, voluntary or involuntary termination or otherwise.

                (y)     "Triggering Event" means the first to occur of the
following events that triggers the redemption of and payment for the Phantom

                                debt convertible into equity that represents, in
                                the aggregate, more than 50% of the then value
                                of the Company, as determined by the Board.

If one of the above described Triggering Events has not occurred on or before
December 31, 2010, this Plan will terminate and no payments will be made with
respect to the Phantom Shares.

                (aa)    "Vested" or "Vesting" means the portion of a
Participant's Award payable to the Participant in the case of termination of
employment with the Company and all Affiliated Corporations for reasons other
than Cause as provided in Section 7. A Participant shall forfeit any unvested
Phantom Shares on the date of termination of employment with the Company and all
Affiliated Corporations. The Participant shall become entitled to payment with
respect to

                                      - 4 -

<PAGE>

such Vested Phantom Shares as a result of a subsequent Triggering Event on or
before December 31, 2010.

        2.2     Gender and Number. Except when otherwise indicated by the
context, the masculine gender shall also include the feminine gender, and the
definition of any term herein in the singular shall also include the plural.

                                    SECTION 3
                               PLAN ADMINISTRATION

        3.1     Administration by the PEC. The Plan shall be administered by the
PEC. The PEC shall consist of the Company's Chief Executive Officer, the
President of Alliant Energy Investments, Inc. and a member of the Board who is
not also an employee of the Company. Subject to approval of its recommendations
by the Company's Board, the PEC shall have exclusive and final authority,
without modifying or changing the Plan, to interpret the Plan consistent with
the intent of the Plan, to prescribe, amend, and rescind rules and regulations
relating to the Plan, to delegate such responsibilities or duties as are
allowable under the Plan or by law and as it deems desirable, and if it so
determines, to cause an audit of the Plan's operations to be conducted by an
independent certified public accounting firm selected by the PEC, and to make
all other determinations necessary or advisable for the administration of the
Plan. In exercising its authority and discretion under the Plan, unless the
context clearly provides otherwise, all decisions of the PEC shall be made in
the sole and absolute discretion of the PEC.

        3.2     Adoption of Rules. The PEC may from time to time adopt such
rules and regulations for carrying out the purposes of the Plan as it may deem
proper and in the best interests of the Company. The PEC may correct any defect,
supply any omission or reconcile any inconsistency in the Plan or in any
agreement entered into hereunder in the manner and to the extent it shall deem
expedient and it shall be the sole and final judge of such expediency. The
determinations, interpretations and other actions of the PEC pursuant to the
provisions of the Plan shall be binding and conclusive for all purposes and on
all persons.

                                    SECTION 4
                            PARTICIPATION IN THE PLAN

        4.1     Eligibility for Participation. The PEC shall establish the
criteria for participation of Eligible Employees in the Plan, select the
Participants, determine the number of Phantom Shares to be granted to each
Participant, and the provisions applicable to such Phantom Shares, which may
include provisions in addition to or different than the provisions of the Plan.
As a general matter, Plan participation shall be extended to those Eligible
Employees of the Company and Affiliated Corporations who, in the opinion of the
PEC, have the opportunity to significantly impact the long-term financial
success of the Company. An Eligible Employee shall become a Participant in the
Plan upon designation as an Eligible Employee by the PEC, and the execution by
the Participant and the Company of a Plan Agreement.

        4.2     Plan Agreement. The Plan Agreement will specify the terms and
conditions of a grant of Phantom Shares to a Participant, including the number
of Phantom Shares granted, the

                                      - 5 -

<PAGE>

date as of which Beginning Company Value shall be calculated, and the amount of
Beginning Company Value, for purposes of calculating the value of the Phantom
Shares, the Performance Cycle associated with the Phantom Shares, the beginning
date for the Measuring Period with respect to the Phantom Shares, the Vesting
arrangement that shall apply to the Participant's Phantom Shares, and any other
provisions that shall apply to the Participant's Phantom Shares, which may
include provisions in addition to or different than the provisions of the Plan.
The Plan Agreement must be signed by the Participant and by an authorized
officer of the Company (other than the Participant).

                                    SECTION 5
                                PERFORMANCE CYCLE

        5.1     Determination of Performance Cycle. The PEC shall determine at
the time of each grant of Phantom Shares hereunder when the Performance Cycle
with respect to the grant of such Phantom Shares shall begin and end.

        5.2     Normal Performance Cycle. The normal Performance Cycle shall be
a five (5) year period, but the PEC may propose and the Board agree to shorter
or longer Performance Cycles. The beginning and ending of the Performance Cycle
will be specified for each grant of Phantom Shares in the Plan Agreement with
each Participant.

                                    SECTION 6
                              PHANTOM SHARE GRANTS

        6.1     Grants. Phantom Shares shall be granted to a Participant based
upon the PEC's assessment of the anticipated role and contribution of the
Participant over the applicable Performance Cycle. Phantom Shares may be granted
with respect to a Performance Cycle at any time during the Performance Cycle.

        6.2     Maximum Number of Phantom Shares and Initial Grant. The total
number of Phantom shares in the Company is set at ten million. The maximum
number of Phantom Shares available for grant during the first Performance Cycle
under the Plan is 500,000 or 5 percent of the total Phantom Shares. Of the
500,000 Phantom shares available for grant under the Plan's first Performance
Cycle, 200,000 shall be for grants to any and all Eligible Employees (excluding
current managers), 200,000 shall be for grants to current management, and
100,000 shall be reserved for future grants to Eligible Employees.

        Regardless of the number of Phantom Shares granted under the Plan with
respect to the first Performance Cycle, the total Vested Phantom Shares
outstanding on the applicable Valuation Date shall share in the allocation of
the Total Award Value in accordance with the provisions of Section 8.1. For
example, if the full 500,000 Phantom Shares are granted with respect to the
first Performance Cycle and were fully Vested, those 500,000 Phantom Shares
would share, in accordance with the provisions of Section 8.1, in the Total
Award Value with respect to such Performance Cycle. Based upon the example set
forth in Section 2.1(c), if a Triggering Event were to occur with respect to the
first Performance Cycle (and on or before December 31, 2010), and if the Total
Award Value is $35,000,000 with respect to the first

                                      - 6 -

<PAGE>

Performance Cycle, the Participants with respect to the first Performance Cycle
would share in the Total Award Value of $35,000,000.

        The PEC shall retain sole discretion to determine the total number of
Phantom Shares to be granted at the beginning of any subsequent Performance
Cycle and the number of Phantom Shares to be awarded to any specific
Participant. The Company anticipates that to promote retention of valued
employees, a disproportionate number of Phantom Shares may be granted in the
initial years of the Performance Cycle. However, as in the first Performance
Cycle, a number of Phantom Shares will be reserved for grants to new
Participants and for additional grants to Eligible Employees. If a Phantom Share
has been redeemed and an Award made to a Participant in accordance with the
provisions of Section 8, or if a Phantom Share has been forfeited or canceled
for any other reason, the Phantom Share shall again be available for grant under
the Plan.

        6.3     Establishment of Individual Phantom Share Accounts. The Company
shall establish, or shall cause to be established, individual accounts for each
Participant which will be unsecured and unfunded and will be maintained for each
grant of Phantom Shares to a Participant under the Plan. The account for each
Participant shall reflect the number of Phantom Shares granted and held by such
Participant and the Beginning Company Value of each such Phantom Share.

                                    SECTION 7
                            VESTING OF PHANTOM SHARES

        7.1     Normal Vesting Schedule. Phantom Shares granted under the Plan
shall Vest at the rate of 20% for each full year of employment with the Company
or an Affiliated Corporation (or as specified in the Plan Agreement for a
particular Participant) completed after the date specified by the PEC for the
beginning of the vesting computation period unless the Board specifies a
different Vesting arrangement with respect to the grant of Phantom Shares to a
particular Participant. The manner in which each Participant's Phantom Shares
shall Vest shall be set forth in the Plan Agreement with the Participant.
Different Vesting arrangements may apply with respect to the grant of Phantom
Shares to different Participants or to different grants of Phantom Shares to the
same Participants.

        7.2     Vesting in Other Circumstances. Except as provided in Section
7.3, a Participant shall become 100% Vested in all of his or her Phantom Shares
in the event of the Participant's death, Permanent Disability or Retirement. A
Participant who is employed by the Company shall also become 100% Vested in all
of his or her Phantom Shares upon the occurrence of a Triggering Event as
defined in Section 2.1(y). The end of a Performance Cycle shall not cause any
acceleration of Vesting for any Participant.

        7.3     Termination for Cause. If a Participant's employment is
terminated for Cause, he shall forfeit all of his or her Vested Phantom Shares
and shall not be entitled to any Award or payment under this Plan with respect
to any Phantom Shares previously granted to such Participant.

                                    SECTION 8
                            PAYMENTS TO PARTICIPANTS

        8.1     Value of Phantom Shares. The value of a Participant's Phantom
Shares will be calculated upon the earlier of a Triggering Event or the end of
the applicable Performance Cycle (the "Valuation Date"), according to the
following formula:

Number of the Participant's Phantom Shares vested at the Valuation Date/total
Vested Phantom Shares in the Plan on the Valuation Date X the Total Award Value.
Notwithstanding the foregoing, the PEC may provide, at the time of the grant of
Phantom Shares to a Participant, whether such Phantom Shares are granted as
different class Phantom Shares or not, that the portion of the Total Award Value
payable to such Participant shall be adjusted to reflect the amount of capital
expenses made at the time of the grant of such Phantom Shares as a percentage of
the total capital expenses budgeted for the Performance Cycle. For example, if a
Participant is awarded Phantom Shares at a time when the Company has expended
$400,000,000 of capital expenditures out of a budgeted $500,000,000 of capital
expenditures, the PEC may provide that the Participant's payment would be based
on the Participant's allocable share of the Total Award Value X 20%.

The Participant's individual Award may be paid in cash or common stock. Common
stock will be used pursuant to Sections 2.1(c), 2.1(m) and 8.4 of the Plan.

The value of each Participant's Phantom Shares shall be determined as soon as
practicable before or after the applicable Triggering Event, but in no event
later than ninety (90) days after the Triggering Event.

        8.2     Payments to Participants - In General. Except as otherwise
provided in this Section and Sections 2.1(c) and 2.1(m), a Participant in the
Plan shall receive payment for his or her Vested Phantom Shares that are
affected by the applicable Triggering Event within thirty (30) days following
the final determination of the Award Value. If a Triggering Event has not
occurred on or before December 31, 2010, the Plan shall terminate and no
payments shall be made to Participants under the Plan.

        8.3     Form of Payment. Payment shall be made to the Participant, if
the conditions of Section 8.4 are satisfied, in shares of the Company's common
stock subject to applicable withholding of income tax and other amounts, no
later than thirty (30) days after the final determination of the value of the
Phantom Shares, except as provided in Sections 2.1(c) and 2.1(m).

        8.4     Use of Common Stock for Payment. If the Company's common stock
is actively traded on an established securities market, payments of amounts due
under this Plan will be made in shares of the Company's common stock. If the
shares of the Company's common stock to be received by a Participant hereunder
may not be immediately sold by the Participant because of restrictions imposed
by federal or state securities laws, the Board shall permit the Participant to
elect to pay the applicable income and other taxes required to be withheld by
causing the Company to withhold from the shares otherwise issuable to the
Participant sufficient shares to

                                      - 8 -

<PAGE>

satisfy the withholding obligation. If the Company is preparing for an IPO
within 120 days or less payment may be made in common stock at the date of its
issuance.

                                    SECTION 9
                               RIGHTS OF EMPLOYEES

        Nothing contained in the Plan or in any Phantom Share granted under the
Plan shall confer upon any Participant any right with respect to the
continuation of his or her employment by the Company or Affiliated Corporation,
or interfere in any way with the right of the Company or Affiliated Corporation,
subject to the terms of any separate employment agreement to the contrary, at
any time to terminate such employment or to increase or decrease the
compensation of the Participant. Whether an authorized leave of absence, or
absence in military or government service, shall constitute a termination of
employment for any purpose of this Plan shall be determined by the Board,
subject to the requirements of applicable law, if any.

                                   SECTION 10
                          DESIGNATION OF BENEFICIARIES

        A Participant may designate a beneficiary or beneficiaries to receive
all or part of the amounts earned by the Participant under the Plan in case of
death. A designation of beneficiary may be replaced by a new designation or may
be revoked by the Participant at any time. A designation or revocation shall be
on a form to be provided by the Company for this purpose and shall be signed by
the Participant and delivered to the Company prior to the Participant's death.
In the case of the Participant's death, the amounts to be distributed to the
Participant under the Plan with respect to which a designation of beneficiary
has been made (to the extent it is valid and enforceable under applicable law)
shall be distributed in accordance with the Plan to the designated beneficiary
or beneficiaries. The amount distributable to a Participant upon death and not
subject to a valid beneficiary designation shall be distributed to the
Participant's estate. If there shall be any question as to the legal right of
any beneficiary to receive a distribution under the Plan, the amount in question
may be paid to the estate of the Participant, in which event the Company shall
have no further liability with respect to such amount.

                                   SECTION 11
                           CHANGES IN ACCOUNTING RULES

        Notwithstanding any other provision of the Plan to the contrary, if,
during the term of the Plan, any changes in the financial or tax accounting
rules applicable to Phantom Shares shall occur which, in the sole judgment of
the PEC, may have a material adverse effect on the reported earnings, assets or
liabilities of the Company, the PEC shall have the right and power to modify as
necessary any then outstanding Phantom Shares, provided, however, that no such
modification shall in any manner adversely affect any Phantom Shares theretofore
granted under the Plan without the consent of the Participant holding such
Phantom Shares.

                                   SECTION 12
                             OTHER EMPLOYEE BENEFITS

        The amount of any compensation deemed to be received by a Participant as
a result of the receipt of Phantom Shares shall not constitute "earnings" with
respect to which any other

                                      - 9 -

<PAGE>

employee benefits of such employee are determined, including without limitation
benefits under any pension, profit sharing, 401(k), life insurance or salary
continuation plan.

                                   SECTION 13
                  PLAN AMENDMENT, MODIFICATION AND TERMINATION

        The Board may at any time terminate, and from time to time may amend or
modify the Plan. The Plan shall terminate upon the sale of all or substantially
all of the assets of the Company, a distribution of all or substantially all of
the assets of the Company to its shareholders, or the merger or reorganization
of the Company if the Company is not the surviving entity. Upon termination of
the Plan, no further Phantom Shares shall be issued, but the provisions of the
Plan shall remain applicable to all Phantom Shares then outstanding at the time
of Plan termination. No amendment, modification or termination of the Plan shall
in any manner adversely affect any Phantom Shares theretofore granted under the
Plan, without the consent of the Participant holding such Phantom Shares.

                                   SECTION 14
                                     SETOFF

        All or part of any amount otherwise due and payable to a Participant
under the Plan may be setoff or applied by the Company against any liability or
reimbursement then due and payable by the Participant to the Company.

                                   SECTION 15
                                  PLAN FUNDING

        Obligations to Participants under the Plan will not be funded, trusteed,
insured or secured in any manner. The Participants under the Plan shall have no
security interest in any assets of the Company, shall have no interest or right
as a shareholder in the Company and shall be only general creditors of the
Company.

                                   SECTION 16
                           NON-ASSIGNABILITY OF RIGHTS

        Except as provided in the Plan, no grant, right, benefit or account of a
Participant under this Plan shall be subject to anticipation, alienation, sale,
assignment, pledge, encumbrance, or charge, and any attempt to anticipate,
alienate, sell, assign, pledge, encumber, or charge the same shall be void. No
right or benefit under the Plan shall in any manner be liable for or subject to
the debts, contracts, liabilities, or torts of the person entitled to such
benefits except as expressly provided herein. If any Participant should become
bankrupt or attempt to anticipate, alienate, sell, assign, pledge, encumber, or
charge any right or benefit hereunder, then such right or benefit shall, in the
discretion of the Company, cease, and in such event, the Company may hold or
apply the Participant's Phantom Shares or any part thereof for the benefit of
the Participant or the Participant's spouse, children, or other dependents, or
any of them in such manner and in such proportions as the PEC shall deem proper.

        The Company shall have the right to deduct from all amounts payable to a
Participant any taxes or other impositions required by law to be withheld upon
such payment.

payment of cash pursuant to the Plan shall be subject to all applicable laws,
rules and regulations.

construed in accordance with and governed by the laws of the State of Colorado.

                                  SEVERABILITY

unenforceable, the same shall not affect, in any respect whatsoever, the
validity of any other provision of the Plan.
