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

ARTICLE IV
CONTRIBUTIONS AND ALLOCATIONS TO ACCOUNTS

        4.1    Accounts.    Each Participant's Account shall consist of the
value of the sum of (1) the Participant's DCRP Account Value determined as of
December 31, 2008, (2) the balance of the Participant's Company DCRP
Contributions Account determined as of December 31, 2008, (3) the Participant's
SERRP Contributions Account, (4) the Participant's SERRP Short-Term Incentive
Contributions Account, (5) the Participant's Supplemental SERRP Contributions
Account and (6) any additional Company contribution accounts that the Company
may, in its sole discretion, create for any purpose.

(a)SERRP Base Salary Contributions Account. The Company may make a contribution
to a SERRP Contributions Account on behalf of a Participant for a specified
amount of the Participant's Base Salary as set forth in a separate participation
notice provided by the Company to the Participant.

(b)SERRP Short-Term Incentive Contributions Account. The Company may make a
contribution to a SERRP Short-Term Incentive Contributions Account on behalf of
a Participant in an amount of the Participant's Short-Term Incentive set forth
in a separate participation notice provided by the Company to the Participant.

(c)Supplemental SERRP Contributions Account. The Company may make contributions
to a Supplemental SERRP Contributions Account on behalf of a Participant for
those Participants who have attained age 55 at the time of initial Plan
eligibility, such amounts to be set forth in a separate participation agreement
entered into between the Company and the Participant.

        4.2    Crediting of Earnings, Gain or Loss on Participant
Accounts.    The Participant's Account shall be credited with earnings, gain or
loss in accordance with the provisions of this Section.

        Trust Investments May Be Different Than Participant Accounts.    The
selection of investment vehicles shall be taken into account solely for the
purpose of crediting earnings, gain or loss on the Participant's Account.
Regardless of whether the trustee invests the Trust in Stock, a Participant's
hypothetical investment in Stock shall be treated as held directly by the
Participant solely for the purpose of determining whether the Participant has
exceeded the employee ownership limitations established by the Company and the
Board.

        Deemed Investments.    The Company shall select the investment vehicles
that are available for investment under the Plan. For the purpose of crediting
earnings, gain or loss on Company contributions, Company contributions shall be
deemed to be credited as of December 31 of the Plan Year. Earnings, gain or loss
shall continue to be credited until the balance in the Participant's Account is
eliminated.

        SERRP Short-Term Incentive Contributions Account Deemed Invested in
Stock.    For the proportion of SERRP Short-Term Incentive Contributions Account
deemed invested in Stock, the Committee shall accumulate the amount of such
Company contributions until the next Trade Date. From the December 31 of the
Plan Year until the next Trade Date, the Committee shall accumulate earnings on
the Company contributions by using the rate of return on a money market fund
selected by the Committee from time to time in its discretion. As of the next
Trade Date, the Committee shall, for bookkeeping purposes only, convert that
portion of the Company contributions plus accumulated earnings to a number of
whole and fractional shares of Stock (calculated to 3 decimal points) by
dividing the dollar value of that portion of the Participant's accumulated
amounts by the Fair Market Value of the Stock as of the Trade Date next
following the December 31 of the Plan Year. The accounting records for the
portion of the Participant's SERRP Short-Term Incentive Contributions Account
invested in Stock shall be maintained in shares rather than dollar values.

5

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

        Crediting of Earnings Based on Selected Investment
Vehicles.    Following the end of day the New York Stock Exchange is open for
business, the Participant's Account shall be credited with earnings, gain or
loss equal to the rate of return earned on investment vehicles with respect to
any portion of the Participant's Account not invested in Stock.

        Crediting of Earnings, Gain or Loss Based on a Stock
Investment.    Stock allocated to a Participant's Account shall be valued at
Fair Market Value. No dividends or other distributions which would be paid with
respect to Stock allocated to a Participant's Account shall be credited to the
Participant's Account.

        If there is any increase or decrease in the number of outstanding shares
of Stock or any change in the rights and privileges of shares of Stock (a) as a
result of the payment of a Stock dividend or any other distribution payable in
Stock, or (b) through a stock split, subdivision, consolidation, combination,
reclassification or recapitalization involving the Stock, the Stock portion of a
Participant's Account shall be adjusted accordingly.

        If the Plan Sponsor distributes assets or securities of persons other
than the Plan Sponsor with respect to the Stock, or if the Plan Sponsor grants
rights to subscribe pro rata for additional shares of Stock or for any other
securities of the Plan Sponsor to the holders of its Stock, or if there is any
other change in the number or kind of outstanding shares or of any stock or
other securities into which the Stock will be changed or for which it has been
exchanged, and if the Committee in its discretion determines that the event
equitably requires an adjustment to any Participant's Account, then such
adjustments shall be made, or other action shall be taken, by the Committee as
the Committee in its discretion deems appropriate.

        Changes in Investment Vehicle Selection.    If the Committee, in its
discretion, authorizes Participants to select the investment vehicle(s) in which
their Account is deemed invested, the Committee shall establish rules and
procedures for the timing and frequency of investment vehicle selection.

        4.3    Withholding Requirement.    The Company shall withhold any taxes
owed from other compensation payable to the Participant. All payments under the
Plan are subject to withholding of all taxes, government mandated social benefit
contributions, or other payments required to be withheld which are applicable to
the Participant.

        6.4    Designation of Beneficiary.    Each Participant may designate one

whom the Participant's Benefit is payable in the event of the Participant's
death. Each designation will automatically revoke any prior designations by the

Control.    Notwithstanding anything to the contrary in this Plan, if a
Participant's employment is terminated (including a termination of employment by
the Participant pursuant to a Constructive Termination) prior to a Change of
Control, and the Participant reasonably demonstrates that such termination was
at the request or suggestion of a third party who has indicated an intention or
taken steps reasonably calculated to effect a Change of Control and a Change of
Control involving such third party occurs, the Participant's entire Benefit
shall be 100% vested and payment of the Participant's entire Benefit shall be
made to the Participant in a lump sum regardless of the Participant's election

to the contrary in this Plan, if a Participant's employment is terminated for

the Company. The Committee may from time to time delegate its responsibilities
as it determines is necessary, in its sole discretion. The Committee may correct
any defect, supply any omission, reconcile any inconsistency in the Plan or in

ARTICLE IX
CLAIMS PROCEDURE

        9.1    Determination of Benefits.    The Company shall distribute
benefit statements reflecting the current amount of the Participant's Benefit to
the Participants on an annual basis.

        9.2    Denial of Claims.    The Committee shall make all determinations
as to the right of any person to a benefit or the amount of such benefit under
this Plan. The Committee shall provide adequate notice in writing to any
claimant whose claim for benefits under the Plan has been denied. The
Committee's claim denial notice shall set forth:

(a)the specific reason or reasons for the denial;

(b)specific references to pertinent Plan provisions on which the denial is
based;

(c)a description of any additional material and information needed for the
claimant to perfect the claim and an explanation of why the material or
information is needed; and

(d)an explanation of the Plan's claims review procedure describing the steps to
be taken by a Participant or Beneficiary who wishes to submit his or her claim
for review, including any applicable time limits, and a statement of the
Participant's or Beneficiary's right to bring a civil action under ERISA
§ 502(a) if the claim is denied on review.

        A Participant or Beneficiary who wishes to appeal the adverse
determination must request a review in writing to the Committee within 60 days
after the appealing Participant or Beneficiary received the denial of benefits.

12

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

        9.3    Appeal Procedure.    A Participant or Beneficiary may appeal a
denial of benefits. Appeals must be made in writing to the Committee within
60 days after the claimant receives the notice of denial. A Participant or
Beneficiary appealing a denial of benefits (or the authorized representative of
the Participant or Beneficiary) shall be entitled to:

(a)submit in writing any comments, documents, records and other information
relating to the claim and request a review;

(b)review pertinent Plan documents; and

(c)upon request and free of charge, reasonable access to, and copies of, all
documents, records and other information relevant to the claim. A document,
record, or other information shall be considered relevant to the claim if such
document, record, or other information (i) was relied upon in making the benefit
determination, (ii) was submitted, considered, or generated in the course of
making the benefit determination, without regard to whether such document,
record, or other information was relied upon in making the benefit
determination, or (iii) demonstrates compliance with the administrative
processes and safeguards designed to ensure and verify that benefit claim
determinations are made in accordance with the Plan and that, where appropriate,
the Plan provisions have been applied consistently with respect to similarly
situated Participants or Beneficiaries.

The Committee shall reexamine all facts related to the appeal and make a final
determination as to whether the denial of benefits is justified under the
circumstances.

        9.4    Decision on Review.    The decision on review of a denied claim
shall be made in the following manner:

(a)The decision on review shall be made by the Committee, who may in its
discretion hold a hearing on the denied claim. The Committee shall make its
decision solely on the basis of the written record, including documents and
written materials submitted by the Participant or Beneficiary (or the authorized
representative of the Participant or Beneficiary). The Administrator shall make
its decision promptly, which shall ordinarily be not later than 60 days after
the Plan's receipt of the request for review, unless special circumstances (such
as the need to hold a hearing) require an extension of time for processing. In
that case a decision shall be rendered as soon as possible, but not later than
120 days after receipt of the request for review. If an extension of time is
required due to special circumstances, the Committee will provide written notice
of the extension to the Participant or Beneficiary prior to the time the
extension commences, stating the special circumstances requiring the extension
and the date by which a final decision is expected.

(b)The decision on review shall be in writing, written in a manner calculated to
be understood by the Participant or Beneficiary. If the claim is denied, the
written notice shall include specific reasons for the decision, specific
references to the pertinent Plan provisions on which the decision is based, a
statement of the Participant's or Beneficiary's right to bring an action under
ERISA § 502(a), and a statement that the Participant or Beneficiary is entitled
to receive, upon request and free of charge, reasonable access to, and copies
of, all documents, records and other information relevant to the claimant's
claim for benefits. A document, record, or other information shall be considered
relevant to the claim if such document, record, or other information (i) was
relied upon in making the benefit determination, (ii) was submitted, considered,
or generated in the course of making the benefit determination, without regard
to whether such document, record, or other information was relied upon in making
the benefit determination, or (iii) demonstrates compliance with the
administrative processes and safeguards designed to ensure and verify that
benefit claim determinations are

13

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

made in accordance with the Plan and that, where appropriate, the Plan
provisions have been applied consistently with respect to similarly situated
claimants.

The Committee's decision on review shall be final. In the event the decision on
review is not provided to the Participant or Beneficiary within the time
required, the claim shall be deemed denied on review.

ARTICLE X
AMENDMENT, MODIFICATION AND TERMINATION

        The Plan Sponsor reserves the right to amend or terminate this Plan at
any time by action of the Board, directly or through delegation by the Board to
one of its committees. The Company may terminate further deferrals under the
Plan for any reason with respect to deferrals for Plan Years beginning after the
date of the Company's termination of the Plan. In the event of such cessation of
deferrals, all other rights and obligations shall continue until all
Participants' Benefits have been paid to all Participants under the terms of the
Plan. At any time following a Change of Control, the Company may terminate the
Plan. If the Company terminates the Plan following a Change in Control within

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.

        11.2    No Right to Continued Employment.    Nothing contained in the
Plan or in any Award granted under the Plan shall confer upon any Participant
any right with respect to the continuation of the Participant's employment by,
or consulting relationship with, the Company, or interfere in any way with the
right of the Company, subject to the terms of any separate employment agreement
or other contract to the contrary, at any time to terminate such services or to
increase or decrease the compensation of the Participant. Nothing in this Plan
shall limit or impair the Company's right to terminate the employment of any
employee. Whether an authorized leave of absence, or absence in military or
government service, shall constitute a termination of service shall be
determined by the Committee in its sole discretion. Participation in this Plan
is a matter entirely separate from any pension right or entitlement the
Participant may have and from the terms or conditions of the Participant's
employment. Participation in this Plan shall not affect in any way a
Participant's pension rights or entitlements or terms or conditions of
employment. Any Participant who leaves the employment of the Company shall not
be entitled to any compensation for any loss of any right or any benefit or
prospective right or benefit under this Plan which the Participant might
otherwise have enjoyed whether such compensation is claimed by way of damages
for wrongful dismissal or other breach of contract or by way of compensation for
loss of office or otherwise.

        11.3    Non-Assignability.    Neither a Participant nor a Beneficiary
may voluntarily or involuntarily anticipate, assign, or alienate (either at law
or in equity) any benefit under the Plan, and the Committee shall not recognize
any such anticipation, assignment, or alienation. Furthermore, a benefit under
the Plan shall not be subject to attachment, garnishment, levy, execution, or
other legal or equitable process. Any attempted sale, conveyance, transfer,
assignment, pledge or encumbrance of the rights, interests or benefits provided
pursuant to the terms of the Plan or the levy of any attachment or similar
process thereupon, shall by null and void and without effect.

        11.4    Participation in Other Plans.    Nothing in this Plan shall
affect any right which the Participant may otherwise have to participate in any
retirement plan or agreement which the Company or an Affiliated Company has
adopted or may adopt hereafter.

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

        11.5    Governing Law.    To the extent not preempted by federal law,
this Plan shall be construed in accordance with, and shall be governed by, the
laws of the State of Colorado.

        11.6    Entire Understanding.    This instrument contains the entire
understanding between the Company and the Employees participating in the Plan
relating to the Plan, and supersedes any prior agreement between the parties,
whether written or oral. Neither this Plan nor any provision of the Plan may be
waived, modified, amended, changed, discharged or terminated without action by
the Board.

        11.7    Provisions Severable.    To the extent that any one or more of
the provisions of the Plan shall be invalid, illegal or unenforceable in any
respect, the validity, legality and enforceability of the remaining provisions
shall not in any way be affected or impaired.

        11.8    Headings.    The article and section headings are for
convenience only and shall not be used in interpreting or construing the Plan.

        11.9    Successors, Mergers, or Consolidations.    Any Agreement under
the Plan shall inure to the benefit of and be binding upon (a) the Company and
its successors and assigns and upon any corporation into which the Company may
be merged or consolidated, and (b) the Participant, and his heirs, executors,
administrators and legal representatives.

        11.10    Section 409A.    Anything in this Plan to the contrary
notwithstanding, no payment to the Participant under this Plan shall be payable
prior to the date that is the earliest of (1) 6 months and 1 day after the
Participant's termination date, (2) the Participant's death or (3) such other
date as will cause such payment not to be subject to interest and additional tax
under Section 409A (with a catch-up payment equal to the sum of all amounts that
have been delayed to be made as of the date of the initial payment).

        For purposes of the Plan, a termination of employment shall be
considered to occur only upon a "separation from service" within the meaning of
Section 409A and the regulations issue pursuant to Section 409A.

        It is the intention of the Company and the Participant that payments or
benefits payable under this Plan not be subject to the additional tax imposed
pursuant to Section 409A. To the extent such potential payments or benefits
could become subject to such Section, the Company and Participant shall
cooperate to structure the payments with the goal of giving the Participant the
economic benefits described herein in a manner that does not result in such tax
being imposed.

        The Plan Sponsor hereby agrees to the provisions of the Plan and in
witness of its agreement, the Plan Sponsor by its duly authorized officer has
executed the Plan on the date written below.
