Exhibit 10(d)1

New Century Energies, Inc. Directors'
Voluntary Deferral Plan

Article 1. Establishment and Purpose of the Plan

      1.1  Establishment.  New Century Energies,  Inc., a Delaware  corporation,
(the  "Company"),  hereby  establishes,  as of the effective  date of the merger
between  Public  Service  Company of Colorado and  Southwestern  Public  Service
Company,  a deferred  compensation  plan for nonemployee  directors as described
herein,  which  shall be  known as the New  Century  Energies,  Inc.  Directors'
Voluntary  Deferral Plan (the "Plan").  The Plan shall assume the liabilities of
the  predecessor   companies  under  the  Public  Service  Company  of  Colorado
Directors'  Voluntary  Deferral Plan or the Southwestern  Public Service Company
Directors' Deferred  Compensation Plan with respect to any nonemployee  director
of either such  predecessor  company who becomes a  nonemployee  director of the
Company.

      1.2 Purpose.  The Plan is intended to provide a means whereby  nonemployee
directors  of the  Company  may  voluntarily  defer  all or a  portion  of their
compensation, subject the terms of the Plan.

Article 2. Administration

      The  Plan  shall  be  administered  by  the  Compensation  Committee  (the
"Committee")  of the  Board of  Directors  (the  "Board")  of the  Company.  The
Committee is authorized to interpret the Plan and may, from time to time,  adopt
such rules and  regulations,  consistent  with the provisions of the Plan, as it
may deem  advisable  to  carry  out the  Plan.  All  determinations  made by the
Committee shall be final.

      The Vice  President  of  Human  Resources  of the  Company  shall,  as the
delegatee of the Committee, be responsible for the day-to-day  administration of
the Plan,  including but not limited to, accepting  deferral  election forms and
accounting for deferrals and distributions under the Plan.

Article 3. Participation in the Plan

      3.1 Eligibility.  All nonemployee  directors of the Company  ("Directors")
shall be eligible to  participate in the Plan. A Director shall be considered to
be a Director  until the close of business on the day  preceding  the earlier of
(i) the first date the individual  becomes a common-law  employee of the Company
or any affiliate of the Company, or (ii) the first date the individual ceases to
be a member of the Board for any reason whatsoever.

      3.2 Election to  Participate.  An eligible  Director may elect to become a
participant in the Plan ("Participant") by electing to defer all or a portion of
his/her  annual  retainer and meeting  fees  ("Compensation").  A separate  such
election shall be allowed with respect to the cash portion of  Compensation  and
with respect to the equity portion of Compensation, with the deferral percentage
with respect to each portion being in such  increments as shall be prescribed by
the Committee. Any such






election  shall  apply to the  Participant's  Compensation  earned  on or after
January 1 of the following calendar year.

      Notwithstanding  the  foregoing,  with respect to an individual  who first
becomes a  Director  on a day other  than the first day of a  calendar  year and
elects  to  participate  in that  year,  any such  election  shall  apply to the
Participant's  Compensation  during  the  calendar  year in which  he/she  first
becomes a Director and subsequent years.

      3.3 Time and Manner of Making  Elections.  Any election as to Compensation
which may be made by a Participant  must be made on or before December 31 of the
year preceding the calendar year to which the election relates;  provided,  that
with respect to an individual  who first becomes a Director  after the beginning
of a calendar year, any such election with respect to the calendar year in which
he/she  first  becomes a Director  must be made  within  thirty  (30) days after
becoming a Director.  With respect to deferrals of  Compensation to be earned in
1997 after the effective date of the Plan,  elections must be made within thirty
(30) days after the effective date of the Plan.  All deferral  elections must be
made on such form as shall be prescribed for this purpose by the Committee.

      3.4 Nature of Elections. Any election as to Compensation which may be made
by a  Participant  with respect to any calendar year shall be  irrevocable  once
made; provided,  however,  that a Director may stop participation in the Plan or
change the  percentage  deferred by delivering  written notice to the Company by
December 31 in the year prior to the year in which Compensation is earned.  Such
written  notice of  termination  of  participation  or change in the  percentage
deferred must be made on such form as may be prescribed  for this purpose by the
Committee.

      Plan  provisions  to the  contrary  notwithstanding,  any  election  as to
Compensation  made by a Participant  with respect to any calendar  year,  unless
changed or revoked by the  Participant  prior to the  expiration of the time for
making such election with respect to each  subsequent  calendar  year,  shall be
deemed to have been made with respect to each subsequent calendar year.

Article 4. Deferred Compensation Account

      4.1  Directors'  Accounts.   The  Company  shall  establish  and  maintain
individual  bookkeeping  accounts  to reflect  deferrals  made by a  Participant
pursuant to this Plan and accounts  transferred  from the Public Service Company
of  Colorado  Directors'  Voluntary  Deferral  Plan or the  Southwestern  Public
Service  Company   Directors'   Deferred   Compensation   Plan.  Two  individual
bookkeeping  accounts shall be maintained with respect to each Participant to be
referred to as a "Cash Account" and a "Stock Account".

      The Participant  shall designate that deferrals made pursuant to this Plan
are to be  credited  to either the Cash  Account or the Stock  Account or that a
portion of such  deferrals,  in such  increments  as shall be  prescribed by the
Committee,  are to be  credited  to  either  of the Cash  Account  or the  Stock
Account.  Such designation shall be made on such form as shall be prescribed for
this purpose by the Company, and

                                   2






shall continue in effect with respect to all subsequent  deferrals until changed
effective as of any January 1 by the Participant.

      The  appropriate  account  shall be  credited  as of the  date the  amount
deferred otherwise would have become due and payable to the Participant.

      4.2  Additions to Cash  Accounts.  The balance of a Cash Account  shall be
reflected in United States Dollars.

      As of the first day of the month after the effective  date of the Plan, an
opening balance shall be credited to the Cash Account of each Participant  equal
to the balance  credited to the Participant  under the Public Service Company of
Colorado Director's Voluntary Deferral Plan, or the balance credited to the Cash
Account  of the  Participant  under  the  Southwestern  Public  Service  Company
Directors'  Deferred  Compensation  Plan, as appropriate,  as of the immediately
preceding day.

      The Cash Account  shall accrue  interest each year at the rate on 1 0-Year
Treasury Notes as of the last auction date of the prior year, or such other rate
as shall be determined by the Compensation  Committee.  Each  Participant's Cash
Account  shall be  credited  with  interest  on the last day of each  month.  An
interest rate, which when compounded  monthly equals the  pre-determined  annual
interest accrual, shall be applied to each month's beginning balance.

      4.3 Additions to Stock  Accounts.  The balance of a Stock Account shall be
reflected in "Stock Units".

      As of the effective date of the Plan, an opening balance shall be credited
to  the  Stock  Account  of  each  Participant  who  was a  participant  in  the
Southwestern Public Service Company Directors' Deferred  Compensation Plan equal
to the  number  of  shares  or  units  credited  to  the  Stock  Account  of the
Participant  under such plan as of the  immediately  preceding  day converted to
Stock  Units on such  basis as  shares of common  stock of  Southwestern  Public
Service  Company are  converted in the merger into shares of common stock of the
Company ("Company Stock").

      As of the date on which  Compensation  affected by a deferral election and
to be credited to a  Participant's  Stock Account would otherwise have been paid
to the  Participant,  the  Participant's  Stock Account shall be credited with a
number of Stock  Units equal to the number of shares of Company  Stock,  to four
decimal  places,  that could have been  purchased  with such  deferrals at a per
share price equal to the  arithmetic  mean between the highest and lowest quoted
selling  prices on the New York Stock  Exchange  Composite  Tape on the date the
Compensation would otherwise have been paid to the Participant (or, if there are
no sales on such date,  then such  arithmetic mean on the next succeeding day on
which there are sales will be used).

      As of the  payment  date of any cash  dividend  on  outstanding  shares of
Company Stock, each Participant's  Stock Account shall be credited with a number
of  additional  Stock Units equal to the number of shares of Company  Stock,  to
four decimal  places,  that could have been  purchased  with the base amount (as
defined  below) at a per share price equal to the  arithmetic  mean  between the
highest and lowest selling prices

                                        3






on the New  York  Stock  Exchange  Composite  Tape for the  payment  date of the
dividend (or, if there are no sales on that date,  then the  arithmetic  mean on
the next  succeeding  day on which  there  are sales  will be  used).  The "base
amount" for  purposes of this  calculation  means the dollar  amount of the cash
dividends  that  would have been paid with  respect  to a number of  outstanding
shares of Company Stock equal to the number of Stock Units (including fractions)
credited  to the  Participant's  Stock  Account  as of the  record  date of such
dividend  (assuming  that  fractional  shares  could be held of record  and that
dividends were paid with respect thereto).

      As of the  payment  date of any  stock  dividend,  stock  split  or  other
distribution on outstanding  shares of Company Stock, each  Participant's  Stock
Account shall be credited  with a number of additional  Stock Units equal to the
number of shares of Company Stock that would have been  distributed with respect
to a number of outstanding  shares of Company Stock equal to the number of Stock
Units (including  fractions)  credited to the Participant's  Stock Account as of
the record date of such  dividend,  split or other  distribution  (assuming that
fractional  shares  could be held of  record  and that  the  dividend,  split or
distribution  was paid with respect  thereto) or the number of shares of Company
Stock that  could  have been  purchased  with the cash  equivalent  of any other
distribution. In the case of a stock dividend, stock split or other distribution
where the  ex-date is after the record  date,  any Stock  Units  credited to the
Participant's  Stock  Account as of the record date of such  dividend,  split or
other distribution but with respect to which a distribution has been made to the
Participant  after the record date and prior to the ex-date will be  disregarded
for purposes of determining the additional credit under this paragraph.

      In the event that the Company  shall at any time be  consolidated  with or
merged with any other  corporation and the Company is not the surviving  entity,
the amounts credited to each  Participant's  Stock Account shall be a continuing
liability of the continuing entity and the number of Stock Units credited to the
Participant's  Stock Account  immediately  prior to the merger or  consolidation
(including  fractions) shall be converted to an equivalent number of Stock Units
based upon the common  stock of such  continuing  entity  (including  fractional
shares)  or other  consideration  on the same  basis as issued  and  outstanding
shares of  Company  Stock are  exchanged  for shares of such  continuing  entity
(assuming  fractional  shares could have been so exchanged  and that  fractional
shares of the continuing entity would have been issued) or other  consideration.
Alternatively,  each Participant may demand,  or the Compensation  Committee may
require,  that a payment be made as of the day preceding  the effective  date of
such consolidation or merger of a cash amount equal to the number of Stock Units
credited  to the  Participant's  Stock  Account  on such day  multiplied  by the
arithmetic  mean  between the highest  and lowest  selling  prices for shares of
Company Stock on the New York Stock Exchange  Composite Tape on such day (or, if
there are no sales on such day, such  arithmetic  mean on the next preceding day
on which there are such sales will be used). Such demand made by the Participant
shall be in writing and shall not be effective  unless filed with the  Secretary
of the  Company  not later than the day  preceding  the  effective  date of such
consolidation or merger.

      4.4 Charges  Against  Accounts.  Any  payments  made to a  Participant  or
his/her  beneficiary shall be charged against the Participant's  Cash Account or
Stock Account, as appropriate.

                                        4






      4.5  Designation  of  Beneficiary.  Each  Participant  shall  designate  a
beneficiary or beneficiaries who, upon the Participant's death, will receive the
amounts that otherwise would have been paid to the  Participant  under the Plan.
All  designations  shall be  signed  by the  Participant  and shall be made on a
"Beneficiary  Designation  Form." Each designation  shall be effective as of the
date delivered by the  Participant  to the Vice President of Human  Resources of
the Company.

      Participants may change their designations of beneficiary by execution and
delivery of a new  Beneficiary  Designation  Form to the Vice President of Human
Resources  of the  Company.  The  payment of amounts  under the Plan shall be in
accordance with the last unrevoked  Beneficiary  Designation  Form that has been
signed by the Participant and delivered by the Participant to the Vice President
of Human Resources prior to the Participant's death.

      In the event that all  beneficiaries  named by a  Participant  pursuant to
this Section 4.5 predecease  the  Participant,  the deferred  amounts that would
have been paid to the Participant or the  Participant's  beneficiaries  shall be
paid to the Participant's estate.

      In the event that a Participant  does not designate a beneficiary,  or for
any reason such  designation  is  ineffective,  in whole or in part, the amounts
that  otherwise  would have been paid to the  Participant  or the  Participant's
beneficiaries under the Plan shall be paid to the Participant's estate.

Article 5. Payment Generally

      5.1 Payment  Generally.  Payment of a Participant's  Cash Account shall be
made in a single lump-sum cash payment or in five (5) annual cash  installments,
as elected by the Participant, beginning as soon as administratively practicable
following  termination as an active member of the Board.  The Participant  shall
make his/her election at the time of his/her  deferral  election on such form as
shall be prescribed for this purpose by the Committee.

      Payment  of a  Participant's  Stock  Account  shall be made in  shares  of
Company  Stock  in  certificate  form,  with the  payment  to be made as soon as
administratively  practicable  following  termination as an active member of the
Board.  The number of shares paid will equal the number of Stock Units  credited
to the  Participant's  Stock Account on his/her last day of service as an active
member of the  Board  (with a cash  equivalent  paid for any  fraction).  If any
additional Stock Units will be credited to the Participant's Stock Account after
his/her  last day of service  as an active  member of the Board as a result of a
cash or stock  dividend  paid after such date,  then,  at the  discretion of the
Committee, the payment to the Participant or his/her beneficiary may be deferred
until after the payment date of such  dividend or an  additional  payment may be
made  consisting of an additional  number of shares equal to the number of Stock
Units credited as a result of such dividend.

      5.2 Hardship Withdrawals.  The Committee shall have the authority to alter
the timing or manner of payment of deferred amounts in the event the Participant
establishes, to the satisfaction of the Committee, severe financial hardship. In
such

                                        5






event,  the  Committee  may,  in its  sole  discretion,  take one or more of the
following actions:

     (i)  Authorize  the  cessation of deferrals by such  Participant  under the
          Plan.

     (ii) Provide  that all, or a portion,  of the balance of the  Participant's
          Cash Account and/or Stock Account shall  immediately be paid in a lump
          sum cash payment.

    (iii) Provide  that all, or a portion,  of the  installment  payable  over a
          period of time shall immediately be paid in a lump sum cash payment.

     (iv) Provide  for  such  other  installment   payment  schedule  as  deemed
          appropriate by the Committee under the circumstances.

      For purposes of this Section 5.2, "severe  financial  hardship" shall mean
any  financial   hardship   resulting  from   extraordinary   and  unforeseeable
circumstances  arising  as a result  of one or more  recent  events  beyond  the
control of the Participant.  In any event, payment may not be made to the extent
such emergency is or may be relieved:  (i) through reimbursement or compensation
by insurance or otherwise,  (ii) by liquidation of Participant's  assets, to the
extent the  liquidation  of such assets would not itself cause severe  financial
hardship;  and (iii) by cessation of deferrals  under the Plan.  Withdrawals  of
amounts  because of a severe  financial  hardship  may only be  permitted to the
extent  reasonably  necessary to satisfy the hardship.  Examples of what are not
considered  to be  severe  financial  hardships  include  the  need  to  send  a
Participant's   child  to  college  or  the  desire  to  purchase  a  home.  The
Participant's Cash Account and Stock Account will be adjusted in accordance with
the Plan up to the date of distribution.

      The severity of the financial  hardship  shall be judged by the Committee.
The Committee's  decision with respect to the severity of financial hardship and
the manner in which, if at all, the participant's future deferral  opportunities
shall  cease,  and/or the manner in which,  if at all,  the  payment of deferred
amounts  to the  Participant  shall be  altered  or  modified,  shall be  final,
conclusive, and not subject to appeal.

      5.3  Death or  Disability.  If a  Participant  dies or  becomes  disabled,
payment  of the entire  remaining  balance of  his/her  Cash  Account  and Stock
Account shall be made in a single  lump-sum  payment within thirty (30) calendar
days following death or termination as an active member of the Board.

      Payment  of the  Participant's  Cash  Account  (or the  remaining  portion
thereof) shall be made in cash.

      Payment  of a  Participant's  Stock  Account  shall be made in  shares  of
Company  Stock in  certificate  form.  The number of shares  paid will equal the
number of Stock Units  credited to the  Participant's  Stock  Account on his/her
last day of service  as an active  member of the Board  (with a cash  equivalent
paid for any fraction).  If any  additional  Stock Units will be credited to the
Participant's  Stock  Account  after  his/her  last day of  service as an active
member of the Board as a result of a cash or stock

                                        6






dividend paid after such date,  then, at the  discretion of the  Committee,  the
payment to the  Participant may be deferred until after the payment date of such
dividend or an additional payment may be made consisting of an additional number
of  shares  equal to the  number  of Stock  Units  credited  as a result of such
dividend.

      For purposes of this  section,  disability  shall mean total and permanent
disability  within the meaning of the pension plan sponsored by the Company,  as
determined in good faith by the Committee,  upon receipt of sufficient competent
medical advice from one or more individuals,  selected by the Committee, who are
qualified to give professional medical advice.

Article 6. Rights of Participants

      6.1 Contractual Obligation. The Plan shall create a contractual obligation
on  the  part  of the  Company  to  make  payments  to or  with  respect  to the
Participant when due under the terms of the Plan.  Payments shall be made out of
the general funds of the Company except as provided in Section 6.2.

      6.2 Unsecured  Interest. No  Participant or party  claiming an interest in
deferred amounts shall have any interest whatsoever in any specific asset of the
Company. To the extent that any party acquires a right to receive payments under
the  Plan,  such  right  shall be  equivalent  to that of an  unsecured  general
creditor of the Company.

      The Company may  establish  one or more  trusts,  with such trustee as the
Committee may approve,  for the purpose of providing for the payment of deferred
amounts.  Such  trust(s) may be  irrevocable,  but the assets  thereof  shall be
subject  to the claims of the  Company's  general  creditors.  To the extent any
deferred  amounts  under the Plan are  actually  paid from any such  trust,  the
Company shall have no further obligation with respect thereto, but to the extent
not so paid, such deferred amounts and contributions shall remain the obligation
of, and shall be paid by, the Company.

Article 7. Withholding of Taxes

      The Company hereby reserves the right to require  Participants to remit to
the  Company  an  amount  sufficient  to  satisfy  Federal,   state,  and  local
withholding  tax  requirements,  or to deduct from payments made pursuant to the
Plan, or from other  payments due from the Company to the  Participant,  amounts
sufficient to satisfy withholding tax requirements.

Article 8. Miscellaneous

      8.1  Nontransferability.  Participants'  rights to deferred  amounts,  and
interest  earned  thereon  under the Plan as well as other  compensation  earned
under the Plan may not be sold, transferred, assigned, or otherwise alienated or
hypothecated,  other than by will or by the laws of descent and distribution. In
no event shall the Company  make any payment  under the Plan to any  assignee or
creditor  of a  Participant.  Any funds so set aside or  acquired  shall  remain
subject to the claims of the creditors of the Company, present and future.

                                        7






      8.2  Severability.  In the event any  provision  of the Plan shall be held
illegal or invalid for any reason, the illegality or invalidity shall not affect
the remaining parts of the Plan, and the Plan shall be construed and enforced as
if the illegal or invalid provision had not been included.

      8.3 Amendment and  Termination.  The Company hereby  reserves the right to
amend, modify, or terminate the Plan or any part thereof,  from time to time, by
action of the  Committee  with  approval  by the  Board;  provided  that no such
amendment or  termination  shall in any  material  manner  adversely  affect any
Participant's rights to deferred amounts,  together with interest earned thereon
as well as other compensation  earned under the Plan, without the consent of the
Participant.

      8.4  Successors.  All  obligations  of the Company under the Plan shall be
binding on any successor to the Company, whether the existence of such successor
is the  result of a direct  or  indirect  purchase,  merger,  consolidation,  or
otherwise,  of all or  substantially  all of the business  and/or  assets of the
Company.  Upon the  occurrence of such an event,  the term  "Company" as used in
this Agreement  shall be deemed to refer to such successor or survivor entity or
entities.

      8.5 Laws  Governing.  This plan shall be construed in accordance  with and
governed by the laws of the State of Colorado.

      8.6 Costs of the Plan. All costs of  implementing  and  administering  the
Plan shall be borne by the Company.

      8.7 Gender and Number.  Except where  otherwise  indicated by the context,
any masculine term used herein shall also include the feminine; the plural shall
include the singular, and the singular shall include the plural.

                             NEW CENTURY ENERGIES
                    SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN

                                  ARTICLE I

                                   GENERAL

        Sec. 1.1  Name of Plan. The name of this plan is "New Century
Energies Supplemental Executive Retirement Plan" (referred to hereinafter as
the "Plan").

        Sec. 1.2 Purpose.  The Plan has been established to provide supplemental
retirement  benefits  and  certain  benefits  upon  disability  or death  before
retirement to certain select management or highly compensated  employees so that
such employees may be retained and their  productive  efforts  encouraged.  This
Plan is a  replacement  as of the  Effective  Date of the PSCo  SERP and the SPS
SERP. On and after the Effective  Date,  the benefits to which  individuals  are
entitled  under  said SERPs are  incorporated  in this Plan and they cease to be
eligible for any separate benefit under those SERPs.

     (a) If the  individual is a Participant in this Plan on or after January 1,
         1998, the benefit shall be determined  and paid solely  pursuant to the
         terms of this Plan, and the provisions of the PSCo SERP or the SPS SERP
         shall no longer apply except as expressly provided in this Plan. ,

     (b) If an individual who was a participant in the PSCo SERP or the SPS SERP
         is not a  Participant  in this Plan on or after  January 1,  1998,  the
         benefit shall be determined  and paid pursuant to the provisions of the
         PSCo SERP or the SPS SERP,  whichever was  applicable,  as in effect on
         December 31, 1997.

        Sec. 1.3  Effective Date. The "Effective Date" of the Plan is January
1, 1998.

        Sec. 1.4  Company. For purposes of this Plan, "Company" means New
Century Energies, Inc., a Delaware corporation, and any Successor Employer
thereof.

        Sec.  1.5  Participating  Employers.  The  Company  is a  "Participating
Employer"  in  the  Plan.   Any   subsidiary  of  the  Company  shall  become  a
Participating Employer in this Plan upon being so designated in a written action
by the  Committee,  effective  as of the date  specified by the  Committee.  Any
Successor  Employer to a  Participating  Employer shall also be a  Participating
Employer.  A  Participating  Employer shall cease to be such effective as of the
date  specified in a written action by the Committee;  provided,  however,  that
such action shall not cause  Participants  employed by such  employer to forfeit
vested benefits accrued prior to such date.

        Sec. 1.6  Construction and Applicable Law. The Plan is intended to be an
unfunded  plan  maintained  primarily  for the  purpose  of  providing  deferred
compensation for a select group of management or highly  compensated  employees,
within the meaning of Sections  201(2),  301(a)(3) and 401(a)(1) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA").  The Plan shall be
administered and construed  consistent with said intent. This Plan also shall be
governed and construed in  accordance  with the laws of the State of Colorado as
applied to contracts  executed and to be wholly  performed  within said state to
the extent that such laws are not  preempted by the laws of the United States of
America.

of employment with the Participating  Employers with a portion equal to 1/240 of

before the Effective Date for purposes of determining the Participant's  benefit
under the PSCo SERP or the SPS SERP. The Committee may, in its sole  discretion,

Participants who participated in the PSCo SERP or the SPS SERP on the day before

Sec. 5. 1) of whichever of the following benefits is applicable:

     (a) If the Participant retires or otherwise separates from service with the
         Participating  Employers  prior to May 1,  2000,  the  accrued  benefit
         determined  as of the date of  separation  from service  under the PSCo
         SERP  or  the  SPS  SERP  (whichever  covered  the  Participant  on the
         Effective Date).

     (b) If the Participant retires or otherwise separates from service with the
         Participating  Employers on or after May 1, 2000,  the accrued  benefit
         determined  under the PSCo SERP or the SPS SERP (whichever  covered the
         Participant  on the  Effective  Date),  determined by assuming that the
         Participant separated from service on May 1, 2000. However, whether the
         Participant  is vested in such benefit shall be determined  pursuant to
         Sec.  4.3  of  this  Plan  as of  the  date  the  Participant's  actual
         separation from service occurs.

Notwithstanding  the  foregoing,  the  Participant  shall  not be  vested in any
benefit  under  this  Plan and the  entire  benefit  shall be  forfeited  if the
Participant's  employment  is terminated  by his or her  Participating  Employer
because of the  Participant's  fraud or dishonesty  which has resulted in, or is
likely to result in, material  economic damage to a Participating  Employer,  as
determined in good faith by the Committee.  The  determination  of the Committee
with respect to the  Participant's  conduct shall be conclusive,  whether or not
there are  related  judicial  or other  proceedings  and  without  regard to the
outcome of any such  proceeding.  A  Participant  who is not  vested  under this
Section  on the date his or her  retirement  or other  separation  from  service
occurs shall not be eligible to receive any benefit under this Plan.

separation  from service  occurs and continue  each month  thereafter  until 240
monthly payments have been made.

        Sec. 5.2 Reduction for Early Retirement.  In the event the Participant's
retirement or other  separation  from service  (except for death or  disability)
from the  Participating  Employers  occurs prior to his or her attainment of age

the month following the, later of (i) the date the  Participant  attains age 55,
or  (ii)  the  date  the  separation  from  service  occurred,  unless  a  later
commencement  date is  elected  pursuant  to Sec.  5.3,  but shall in all events
commence by the first day of the month  coinciding  with or next  following  the
date the  Participant  attains age 62. The payments  shall  continue  each month
thereafter  until a total of 240 monthly  payments have been made. The amount of
the Participant's Normal Retirement Benefit shall be reduced by five-twelfths of

later than 12 months before the date payments are to commence under Sec. 5. 1 or

Actuarial  Equivalent  basis, in the form of a single lump sum or in the form of
any annuity option permitted under the Retirement Plan.

        Sec.  5.4  Commencement  Date. Retirement  benefits  shall  commence  in
accordance  with Sec. 5.1 and Sec. 5.2;  provided,  however,  that the Committee
may, in its discretion,  after receiving a Participant's lump sum election under
Sec.  5.3,  determine  that  payment  shall be made at a later  date  than  that
specified or requested by the Participant. In the event that all or a portion of
any  payment  under  this  Article  V shall  be  rendered  nondeductible  by the
Participating  Employers pursuant to Internal Revenue Code Section 162(m) or any
successor provision at the time of the Participant's  retirement or termination,
the Committee shall defer any such  nondeductible  portion to a time period when
such payment would otherwise be deductible by the Participating  Employers,  and
shall adjust the deferred  payment on an Actuarial  Equivalent  basis to reflect
the date payment is actually made.

        Sec.  5.5  Disability  Before  Retirement.   If,  while  employed  by  a
Participating  Employer, a Participant becomes totally and permanently disabled,

Participant  dies  while  employed  by a  Participating  Employer  (and prior to
commencement of a pension due to disability  under Sec. 5.5), the  Participant's
Beneficiary  shall receive,  beginning the first day of the month  following the
Participant's  death, a monthly payment equal to 50% of the Participant's Normal
Retirement  Benefit until a total of 240 monthly  payments have been made to the
Beneficiary.

     Sec. 5.7 Death After  Termination  of Employment.  If a vested  Participant
dies  after  leaving  the  employ of the  Participating  Employers  and prior to

         which  the   Participant  was  receiving   immediately   preceding  the
         Participant's  death,  (or would have been  entitled  to  receive  upon
         attaining age 62 if the Participant died prior to commencing to receive
         payments).

     (b) The  monthly  benefit  determined  under  subsection  (a) shall be paid
         beginning  the first  day of the  month  after the date of death if the

         Participant  would have attained age 62.  Payments shall cease when the

        Sec. 6.1 Administration by the Committee. The Committee shall administer
the Plan, establish,  adopt, or revise such rules and regulations as it may deem

otherwise.  No Participant or Beneficiary shall have any interest  whatsoever in
any  specific  asset of the  Participating  Employers.  To the  extent  that any
Participant or Beneficiary acquires a right to receive payments under this Plan,

accruals  (including  any  continuing  accruals under the provisions of the PSCo
SERP or the SPS SERP).

        Sec. 7.2  Termination  of Plan.  The Board may terminate the Plan at any
time. After such termination, no employee shall become a Participant, no further
benefits  shall accrue under the Plan,  and each  Participant  shall become 100%
vested  in  the  benefit  accrued  prior  to the  date  of  termination.  At the
discretion of the  Committee,  the benefits  accrued prior to termination of the
Plan may be either distributed to Participants (or Beneficiaries in the event of
death) in a lump sum on an Actuarial Equivalent basis as of a date determined by
the  Committee  which  is after  the  date of  termination,  or  distributed  in
accordance with Article V.

successively)  to  whom  any  benefit  under  the  Plan  otherwise  due  to  the
Participant may be paid in case of the Participant's  death before receiving any
or all of such  benefit.  Any  subsequent  designation  shall  revoke  all prior
designations by the same  Participant.  If the Participant  does not designate a
beneficiary,  or if none of those  designated  are alive or existing at the time
the  Beneficiary  is to be identified to receive a benefit under the Plan, or if
the  person  receiving  benefits  as the  beneficiary  hereunder  dies  with  no
contingent  beneficiary  designated,  the Beneficiary shall be the Participant's
estate.

     Sec. 8.2 Benefits May Not Be Assigned or  Alienated.  Neither a Participant
nor any Beneficiary shall have the right to sell, assign, transfer,  encumber or
otherwise  convey any right to receive  any  payment  hereunder.  No part of the

payment of any debts or judgments owed by a Participant or any other person.

hereof are for convenience of reference, shall not be considered a part of the

     Sec. 1.1 Name of Plan.  The name of this plan is the "New Century  Energies
Salary Deferral and Supplemental  Savings Plan for Executive Officers" (referred
to hereinafter as the "Plan").

      Sec.  1.2  Purpose  The Plan has been  established  to provide  additional
future income to certain select executive  officers through voluntary  deferrals
of Compensation and Company Credits related to matching  contributions under the
Savings Plan.  Those portions of the Prior PSCo Plan and the Prior SPS Plan that
covered  individuals  who are  Participants in this Plan as of July 1, 1998 were
merged into this Plan as of that date,  and the  benefits  of such  Participants
under the  applicable  Prior Plan shall  thereafter be provided  pursuant to the
provisions of this Plan.

     Sec. 1.3 Effective  Date. The "Effective  Date" of the Plan, the date as of
which the Plan was established, is July 1, 1998.

     Sec. 1.4 Company.  For purposes of this Plan,  "Company"  means New Century

Participating Employer in this Plan upon being so designated in a written action
by the  Committee,  effective  as of the date  specified by the  Committee.  Any
Successor  Employer to a  Participating  Employer shall also be a  Participating
Employer.  A  Participating  Employer shall cease to be such effective as of the
date  specified in a written action by the Committee;  provided,  however,  that
such action shall not cause  Participants  employed by such  employer to forfeit
benefits accrued prior to such date.

      Sec. 1.6  Construction  and Applicable  Law. The Plan is intended to be an
unfunded  plan  maintained  primarily  for the  purpose  of  providing  deferred

within the meaning of Sections  201(2),  301(a)(3) and  401(a)(1) of ERISA.  The
Plan is not intended to qualify  under Code Section  401(a) or 403(a).  The Plan
shall be administered and construed  consistent with said intent. This Plan also
shall be governed  and  construed  in  accordance  with the laws of the State of
Colorado as applied to contracts executed and to be wholly performed within said
state to the extent that such laws are not  preempted  by the laws of the United
States of America.

               elected to be deemed to have been invested in Common Shares.

               30, 1998, and the Participant's  Directable Stock Account will be
               credited with a number of Common Shares equal to the value of the
               Participant's  other  accounts  under  the Prior SPS Plan on that
               date,  in each case  divided  by the  average of the high and low

      (b)  An  employee  who is  designated  as a  Participant  before  the last
           calendar  quarter of a Plan Year may wait until the following year to
           make deferrals of Compensation or may elect to make deferrals for the
           partial Plan Year (for Compensation earned after the calendar quarter
           of the election to defer),  and in either case such Participant shall
           be eligible  for Company  Credits  under  Section 4.2 for the partial
           Plan Year, unless the Committee  determines otherwise at the time the
           employee is designated as a Participant.

     Sec. 3.2 Duration of  Participation.  An employee who becomes a Participant
shall  continue to be  eligible to make  elections  under Sec.  4.1  thereafter,
subject to the following:

      (a) The Participant's deferrals shall cease on the earliest of.

           (1) The  date  the  Participant   terminates   employment  with  the
               Participating Employers.

           (2) The date  specified in a written  notice  issued by the Committee
               revoking the individual's status as a Participant.

           (3) The date the  Participant  fails to meet the  requirements of any
               regulations  which may be issued by the  Department of Labor that
               define  the  phrase   "select   group  of  management  or  highly
               compensated employees" under ERISA.

                                       -4-





      (b)  An individual  shall continue to be a Participant for purposes of the
           provisions of the Plan other than Sec. 4.1 or Sec. 4.2 until the date
           all of his or her Accounts have been distributed.

      (c)  If an employee who has elected to make deferrals  under Sec. 4. 1 for
           a particular Plan Year is subsequently  determined not to be eligible
           to be a  Participant  for that Plan  Year,  the  employee's  deferral
           election  for that year will be canceled  and any  amounts  which may
           have already been deferred for that year will be promptly refunded to
           the employee.

     Sec.  3.3 No Guarantee of  Employment.  Participation  in the Plan does not
constitute  a  guarantee  or  contract  of  employment  with  the  Participating
Employers.  Such  participation  shall in no way  interfere  with any rights the
Participating  Employers  would  have in the  absence of such  participation  to
determine the duration of the employee's employment.

                                   ARTICLE IV

                  DEFERRED COMPENSATION AND CREDITS TO ACCOUNTS

      See. 4.1 Election to Defer Compensation. An eligible Participant may elect
to have  Compensation with respect to each Plan Year credited to his or her Cash
Account and/or Directable Stock Account rather than being paid in cash,  subject
to any limitations that may be imposed by the Committee. Elections shall be made
on forms  specified by the  Committee  for  purposes of this Plan,  and shall be
filed in the manner specified by the Committee. The Compensation for a Plan Year
of a Participant who elects deferrals under this section shall be reduced by the
percentage or amount so elected, subject to the following:

      (a)  Elections for each Plan Year must be filed during the election period
           specified by the Committee for that Plan Year,  which period must end
           on or prior to  December  31 of the  previous  year,  subject  to the
           following:

           (1) If an individual (other than a former  Participant) is designated
               as a Participant  during a Plan Year,  any election for that Plan
               Year must be filed within 30 days after the date the  Participant
               received  the  notice  of  participation,   and  deferrals  shall
               commence as of the first day of the  calendar  quarter  after the
               election  is received by the  Committee.  Such an election  shall
               apply to Base  Salary  payable  during that Plan Year for payroll
               periods  beginning  on or after the first day of said quarter and
               to any incentive compensation for that Plan Year which is subject
               to a requirement  that the individual  remain  employed to a date
               that is on or after the first day of said quarter.

           (2) A former Participant who is again designated as a Participant may
               not commence deferrals until January 1 of the Plan Year following
               the  designation of  participation,  and an election to defer for
               such Plan Year must be made prior to said January 1.

           (3) Except as provided in paragraph (4),  elections for the Plan Year
               commencing July 1, 1998 must be filed by June 30, 1998.

           (4) Notwithstanding  anything  in  this  Plan to the  contrary,  if a
               Participant was a participant in the Prior PSCo Plan or the Prior
               SPS Plan on June 30, 1998, any

                                       -5-





               election in effect under such Prior Plan shall continue in effect
               for  purposes  of this  Plan for the 1998 Plan  Year,  and no new
               election shall be allowed under this Plan for that Plan Year. Any
               such election under a Prior Plan shall not apply to  Compensation
               with respect to Plan Years commencing after 1998.

     (b)  The  Participant  may elect to defer either (i) any whole  percent (in
          10% increments) of Compensation payable with respect to the Plan Year,
          or (ii) any percent or dollar amount of  Compensation up to the amount
          required for the  Participant  to receive the maximum  Company  Credit
          under Sec. 4.2. However,  the total deferrals during any Plan Year may
          not reduce the  Participant's  Compensation  payable  during that Plan
          Year (after  deduction of the deferrals  under this Plan) to less than
          $100,000 (or the dollar amount in effect for that Plan Year under Code
          Section 414(q)(1)(B), if greater).

     (c)  The deferred  compensation  credited under this section on behalf of a
          Participant  shall be  allocated  to the  Participant's  Cash  Account
          and/or  Directable Stock Account (as elected by the Participant) as of
          the date that the  Compensation  would otherwise have been paid to the
          Participant  in cash. The amount of Common Shares to be allocated to a
          Directable Stock Account shall be determined by dividing the credit by
          the average of the high and low sales  prices of a Common Share on the
          New York Stock  Exchange on the business day  proceeding  the date the
          credit is made.

      (d)  The Participant must file a separate  deferral election for each Plan
           Year with respect to which  deferrals are to be made under this Plan.
           An election for a Plan Year shall become irrevocable on the first day
           of that year,  subject to subsection  (e).  Elections  will not carry
           over  into  subsequent  Plan  Years.   However,  an  election  for  a
           particular Plan Year shall apply to all Compensation  with respect to
           that Plan Year,  including  incentive bonuses or other amounts earned
           during that year but paid in subsequent Plan Years.

      (e) Notwithstanding the foregoing provisions of this section:

           (1) All deferrals by a Participant shall cease as of (i) the date the
               Participant  receives a hardship  withdrawal  under any qualified
               defined   contribution   plan  subject  to  Code  Section  401(k)
               maintained by the Company or any of its affiliates which requires
               that  deferrals  be  suspended  for  a  certain  period  of  time
               following  such  withdrawal,  or (ii) the  date  the  Participant
               receives  a  withdrawal  from  this  Plan  for  severe  financial
               hardship  due  to an  unforeseeable  emergency  under  Sec.  5.5.
               Deferrals  under this section may not recommence  until the first
               day of the second Plan Year  beginning  after the date  deferrals
               ceased  under the  previous  sentence,  and no further  deferrals
               shall be made from  Compensation with respect to Plan Years prior
               to said second Plan Year.

           (2) The Committee may in its sole  discretion  cancel a Participant's
               deferral election for the current Plan Year (and for Compensation
               not yet paid with  respect to any  previous  Plan Years) upon the
               request of a  Participant  if the  Committee  determines  that an
               event has occurred which would make the Participant  eligible for
               a   withdrawal   for  severe   financial   hardship   due  to  an
               unforeseeable  emergency  under Sec.  5.5.  Deferrals  under this
               section may not recommence until the first day of the second Plan
               Year beginning after the date deferrals ceased under the previous
               sentence,   and  no   further   deferrals   shall  be  made  from
               Compensation with respect to

                                       -6-





               Plan Years prior to said second Plan Year.  The  Participant  may
               request that deferrals cease under this paragraph  whether or not
               the Participant requests a withdrawal under Sec. 5.5.

     Sec.  4.2  Company  Credits.  Subject to the  Committee's  discretion,  the
Nondirectable  Stock Account of each eligible  Participant  will be credited for
each Plan Year with a Company  Credit  representing  a number of Common  Shares,
determined as follows:

      (a)  The  Company  Credit  for a Plan  Year  will be equal  to the  amount
           determined  under  paragraph  (1) minus the amount  determined  under
           paragraph (2), with the result divided by the amount determined under
           paragraph  (3),  and with the result  then  rounded  to four  decimal
           places, as follows:

           (1) A dollar amount equal to 50% of the smaller of (i) the sum of the
               amount of Base Salary the  Participant  deferred  under this Plan
               for the Plan Year and the Participant's  pre-tax contributions to
               the  Savings  Plan  for  the  Plan  Year,  or  (ii)  8 %  of  the
               Participant's  "compensation" for the Plan Year recognized by the
               Savings Plan for purposes of determining  matching  contributions
               under that Plan (but  disregarding the limit on such compensation
               under Code Section 401(a)(17)); minus

           (2) The dollar amount of matching  contributions actually made to the
               Savings Plan for the Participant for the Plan Year; divided by

           (3) The average of the high and low sale prices of a Common  Share on
               the New York Stock  Exchange on the  business day  preceding  the
               date the matching contribution is made to the Savings Plan.

      (b)  Notwithstanding  subsection  (a),  a  Participant  will  receive  the
           Company Credit for a Plan Year only if the  Participant  participates
           in the Savings  Plan and makes the maximum  dollar  amount of pre-tax
           contribution permitted by the Savings Plan for that year.

      (c)  The Company Credit for an eligible  Participant  for a Plan Year will
           be allocated to the Participant's  Nondirectable Stock Account on the
           date the  matching  contribution  for such Plan Year is (or would be)
           made under the Savings Plan.

      (d)  Each Participant's Nondirectable Stock Account shall also be credited
           with any Common Shares  deferred under any annual  incentive plan, or
           other plan that may be established  by the Company,  for that portion
           of the award which is otherwise payable in Common Shares. Such credit
           shall  occur as of the date such  shares  would  otherwise  have been
           distributed to the Participant.

      (e)  Notwithstanding  the  foregoing,  the Company  Credits for the period
           from July I to  December  31, 1998 under this  Section  will be based
           only on compensation and contributions during that period.

     Sec. 4.3 Investment Credits and Valuation of Accounts. The Accounts of each
Participant  will be adjusted as of each  Valuation  Date to reflect  Investment
Credits,  deferrals  allocated to the Account  under Sec. 4. 1, Company  Credits
allocated under Sec. 4.2, credits to Stock Accounts

                                       -7-





under Sec. 4.4,  adjustments of Stock Accounts under Sec. 4.5, and distributions
from Accounts under Article V, since the previous Valuation Date, subject to the
following:

      (a)  Investment  Credits  on  each  Cash  Account  will  be  based  on the
           investment  index or indexes  selected by the  Participant to measure
           the  deemed  rate of  investment  return on his or her  Account.  The
           investment  indexes will be the same as the investment  options under
           the  Savings  Plan  (except  the NCE  Stock  Fund),  and  such  other
           investment  options as the Committee  makes available under this Plan
           from time to time.

      (b)  A Participant may file separate investment elections for the existing
           Cash  Account  balance  and for future  amounts to be credited to the
           Participant's  Cash Account  and/or  Directable  Stock  Account.  The
           Participant may also elect to have amounts transferred between his or
           her Cash Account and Directable  Stock Account.  The amount of Common
           Shares to be credited upon a transfer into a Directable Stock Account
           shall be determined as provided in Sec. 4. 1 (c).

      (c)  All investment  elections  shall be in accordance with such rules and
           regulations  as the Committee may  establish  from time to time.  The
           Committee may also  establish  such  procedures  for the valuation of
           Accounts as the  Committee  determines  in its sole  discretion  will
           reasonably  reflect the period of time amounts were  credited to each
           Account.

      (d)  Notwithstanding the foregoing,  the Committee may modify or disregard
           an  investment  election  filed by a  Participant  to the  extent the
           Committee determines that such action is necessary to comply with the
           terms  of this  Plan or to  avoid  adverse  tax  consequences  to the
           Participant or the Participating Employers.

      (e)  Notwithstanding   anything   in  the  Plan  to  the   contrary,   the
           Participating  Employers shall be under no obligation to purchase any
           investments  used for determining  Investment  Credits or to purchase
           Common  Shares.  The  investment  indexes and Common  Shares are used
           solely for the recordkeeping purpose of measuring gains and losses on
           each Participant's  Accounts,  and the Participant's Accounts are not
           actually being invested in the indexes or in Common Shares.

     Sec. 4.4 Dividends on Common  Shares.  Each  Participant's  Stock  Accounts
shall be credited as of each  dividend  payment date for Common Shares with that
number of shares obtained by dividing:

      (a)  the  amount of any  dividends  that would be payable on the number of
           shares  (including  fractional  shares,  carried out to four  decimal
           places)  credited to each Stock Account of such Participant as of the
           record date for payment of such dividend, by

      (b)  the  average of the high and low sale price of a Common  Share on the
           New  York  Stock  Exchange  on the  day  preceding  the  date of such
           dividend payment.

      See. 4.5 Adjustment of Stock Accounts for Splits,  Dividends,  Etc. In the
event of any change in the outstanding Common Shares of the Company by reason of
any share dividend or split, recapitalization,  merger, consolidation, spin-off,
reorganization,  combination  or  exchange  of Common  Shares  or other  similar
corporate change, the Committee shall make appropriate  adjustment in the number
of the Common Shares in the Participants' Stock Accounts.

                            DISTRIBUTION OF ACCOUNTS

     Sec. 5.1 Time for Distribution. Except as provided in Sec. 5.5 and the last
paragraph of this Section,  all Account  balances  shall be  distributed  to the
Participant or Beneficiary within 30 days after the earliest to occur of:

      (a) The Participant's Retirement,

      (b) The  date the  Participant  is  determined  by the  Committee  to have
          incurred a Disability.

      (c) The date of the Participant's death.

      (d) Any  other  termination  of the  Participant's  employment  with  the
          Participating Employers.

However,  any Company  Credit for the final  partial Plan Year of  participation
shall  be  distributed  at  the  time  it  is  credited  to  the   Participant's
Nondirectable Stock Account.

     Sec. 5.2 Manner of Payment. The balance in a Participant's Cash Account and
the value of whole and  fractional  shares in the  Participant's  Stock Accounts
shall be paid in cash in a single lump sum payment.

      Sec.  5.3 Amount of  Payment.  The amount of cash to be  distributed  to a
Participant with respect to the Participant's  Cash Account shall be the balance
of such account as of the end of the month prior to the distribution. The amount
of cash to be  distributed  to a Participant  with respect to the  Participant's
Stock Accounts shall be the number of shares credited to such Accounts as of the
end of the month prior to the distribution multiplied by the average of the high
and low sales price of a Common Share on the New York Stock Exchange on the last
trading day of the month prior to the distribution.

      Sec. 5.4 Beneficiary Designation Each Participant shall have the right, at
any time, to designate any person or persons as Beneficiary or  Beneficiaries to
whom  payments  under this Plan shall be made in the event of the  Participant's
death prior to complete distribution of the amount credited to the Participant's
Accounts. Each Participant shall have the right to change his or her Beneficiary
designation at any time. Each  Beneficiary  designation  shall become  effective
only when filed in writing with the Committee during the Participant's life on a
form  prescribed  by the  Committee.  The  rights of each  Beneficiary  shall be
subject to the terms and  conditions  specified on the  designation  form to the
extent  consistent  with  the  terms  of the  Plan.  If a  Participant  fails to
designate a Beneficiary as provided  above,  or if all designated  Beneficiaries
predecease the  Participant,  then the  Beneficiary  shall be the  Participant's
estate.

     Sec. 5.5 Distributions for Severe Financial  Hardship.  Notwithstanding the
foregoing  sections of this Article V, the Committee in its sole  discretion may
approve a request  by a  Participant  for a  withdrawal  from the  Participant's
deferred amounts due to an unforeseeable emergency. An "unforeseeable emergency"
is severe  financial  hardship to the  Participant  resulting  from a sudden and
unexpected  illness or accident of the Participant or of a dependent (as defined
in Code Sec. 152(a) of the Participant,  loss of the Participant's  property due
to casualty, or other similar extraordinary and

                                       -9-





unforeseeable  circumstances  caused  by an  event  beyond  the  control  of the
Participant.  Unforeseeable  emergencies specifically do not include the need to
pay for the education of a Participant's child or the desire to purchase a home.
Any such early  withdrawal  approved by the  Committee may not exceed the amount
reasonably  necessary  to meet  the  emergency.  Payment  may not be made to the
extent that such hardship is or may be relieved by any of the following means:

      (a)  Through reimbursement or compensation by insurance or otherwise.

      (b)  By  liquidation  of  the  Participant's  assets,  to the  extent  the
           liquidation  of such assets would not itself  cause severe  financial
           hardship.

      (c) By cessation of deferrals under the Plan.

     Sec. 5.6 Modification of Elections for Tax Considerations.  Notwithstanding
anything to the contrary in the  foregoing  sections of this Article V or in any
election filed by a Participant:

      (a)  If the  Committee  determines,  based on advice of legal counsel or a
           final  determination  by the Internal  Revenue  Service or a court of
           competent jurisdiction, that a Participant or Beneficiary may be held
           to be in  constructive  receipt  of  benefits  under  this  Plan  and
           required to recognize such benefit  immediately or retroactively  for
           income tax purposes,  the Committee may in its sole  discretion  take
           either of the following actions:

           (1) Distribute  the entire  affected  benefit in a single lump sum as
               soon as administratively feasible.

           (2) Take written action modifying the  Participant's  election and/or
               the terms of the Plan  (retroactively,  if necessary) in a manner
               that win eliminate the allegation of  constructive  receipt while
               at the same time carrying out the  Participant's  original intent
               to the extent possible.

      (b)  The Committee may postpone any payment to be made to a Participant or
           Beneficiary  until a  subsequent  fiscal  year  of the  Participating
           Employers to the extent the  Committee  determines to be necessary in
           order to avoid the loss of an income tax deduction under Code Section
           162(m).

      Sec. 5.7 Withholding and Taxes. The benefits payable under this Plan shall
be subject to the  deduction  of any  federal,  state,  or local income taxes or
other taxes which are required to be withheld  from such  payments by applicable
laws and  regulations.  Any Social  Security (FICA) taxes which must be withheld
prior to the distribution of benefits to the Participant  shall be withheld from
the  amounts  deferred,  or  from  the  Participant's  other  compensation,   as
determined by the Committee.  The Participating  Employers provide no assurances
or guarantees  regarding the tax treatment of amounts  deferred or payments made
under this Plan.  Each  Participant  is solely  responsible  for any  applicable
income, excise and other taxes,  penalties or interest (including any excise tax
under Code Section 4999).

                                 ADMINISTRATION

      Sec. 6.1  Administration by the Committee.  The Committee shall administer
the Plan, shall establish, adopt, or revise such rules and regulations as it may

payment of any debts or judgments  owed by a  Participant  or any other  person.
However,  the Committee may offset the  obligations  to the  Participant  or the
Participant's  Beneficiary  hereunder by any amounts the Participant owes to the
Participating Employers,  provided that such amounts owed by the Participant are
not  related  in any way to the  benefits  payable  under this Plan and were not
incurred in  anticipation  of the benefits to which the  Participant  may become
entitled hereunder.

      Sec. 8.3  Incompetency.  Every person receiving or claiming benefits under
this Plan shall be conclusively presumed to be mentally competent until the date
on which the Committee receives a written notice in a form and manner acceptable
to  the  Committee  that  such  person  is  incompetent  and  that  a  guardian,
conservator  or other person  legally  vested with the care of his or her estate
has been appointed. In such event, the Committee may direct payments of benefits
to such  guardian,  conservator  or other person legally vested with the care of
the person's estate and any such payments so made shall be a complete  discharge
of the Participating Employers to the extent so made.

     Sec.  8.4  Notices.  Notices  required  by  this  Plan to be  given  to the
Committee or a  Participant  shall be in writing and shall be considered to have
been duly  given or  served if  personally  delivered,  or sent by first  class,

     Sec.  8.10 Construed  as a Whole.  The  provisions  of the Plan shall be
construed  as a whole in such manner as to carry out the  provisions  hereof and
shall not be construed separately without relation to the context.

     Sec. 1.1 Name of Plan.  The name of this plan is the "New Century  Energies
Salary  Deferral and  Supplemental  Savings Plan for Key Managers"  (referred to
hereinafter as the "Plan").

      Sec.  1.2 Purpose.  The Plan has been  established  to provide  additional
future  income  to  certain  key  managers   through   voluntary   deferrals  of
Compensation  and Company  Credits related to matching  contributions  under the
Savings  Plan.  The Prior  PSCo Plan and the  Prior  SPS  Plan,  other  than the
portions of those plans which covered  individuals  who are  participants in the
New Century Energies Salary Deferral and Supplemental Savings Plan for Executive
Officers  on July 1,  1998,  were  merged  into this Plan as of that  date.  The
benefits  of all  individuals  covered by the  portions of the Prior Plans which
were  merged  into  this Plan  shall  thereafter  be  provided  pursuant  to the
provisions of this Plan. If an  individual's  benefit from a Prior Plan has been
merged into this Plan but the  individual  is not  designated  as a  Participant
under  this  Plan,  the  individual  shall   nevertheless  be  deemed  to  be  a
"Participant"  under the  provisions  of this Plan (other  than  Article III and
Sections  4.1 and 4.2) until the  benefits  with  respect to the Prior Plan have
been distributed.

in the Plan. Any subsidiary of the Company shall become a Participating Employer
in this Plan upon being .so  designated  in a written  action by the  Committee,
effective as of the date specified by the Committee. Any Successor Employer to a
Participating  Employer shall also be a Participating  Employer. A Participating
Employer  shall cease to be such effective as of the date specified in a written
action by the  Committee;  provided,  however,  that such action shall not cause
Participants employed by such employer to forfeit benefits accrued prior to such
date.

      Sec. 1.6  Construction  and Applicable  Law. The Plan is intended to be an
unfunded  plan  maintained  primarily  for the  purpose  of  providing  deferred
compensation for a select group of management or highly  compensated  employees,
within the meaning of Sections  201(2),  301(a)(3) and  401(a)(1) of ERISA.  The
Plan is not intended to qualify  under Code Section  401(a) or 403(a).  The Plan
shall be administered and construed  consistent with said intent. This Plan also
shall be governed  and  construed  in  accordance  with the laws of the State of
Colorado as applied to contracts executed and to be wholly performed within said
state to the extent that such laws are not  preempted  by the laws of the United
States of America.

      (c)  If an employee who has elected to make deferrals under Sec. 4.1 for a
           particular Plan Year is subsequently determined not to be eligible to
           be a Participant for that Plan Year, the employee's deferral election

     Sec.  3.3 No Guarantee of  Employment.  Participation  in the Plan does not
constitute  a  guarantee  or  contract  of  employment  with  the  Participating
Employers.  Such  participation  shall in no way  interfere  with any rights the
Participating  Employers  would  have in the  absence of such  participation  to
determine the duration of the employee's employment.

                                   ARTICLE IV

                      DEFERRED COMPENSATION AND CREDITS TO ACCOUNTS

      Sec. 4.1 Election to Defer Compensation. An eligible Participant may elect
to have  Compensation with respect to each Plan Year credited to his or her Cash
Account and/or Directable Stock Account rather than being paid in cash,  subject
to any limitations that may be imposed by the Committee. Elections shall be made
on forms  specified by the  Committee  for  purposes of this Plan,  and shall be
filed in the manner specified by the Committee. The Compensation for a Plan Year
of a Participant who elects deferrals under this section shall be reduced by the
percentage or amount so elected, subject to the following:

      (a)  Elections for each Plan Year must be filed during the election period
           specified by the Committee for that Plan Year,  which period must end
           on or prior to  December  31 of the  previous  year,  subject  to the
           following:

          (1)  If an individual (other than a former  Participant) is designated
               as a Participant  during a Plan Year,  any election for that Plan
               Year must be filed within 30 days after the date the  Participant
               received  die  notice  of  participation,   and  deferrals  shall
               commence as of the first day of the  calendar  quarter  after the
               election  is received by the  Committee.  Such an election  shall
               apply to Base Salary payable during that Plan

                                       -5-





               Year for payroll  periods  beginning on or after the first day of
               said quarter and to any incentive compensation paid for that Plan
               Year which is subject to a requirement that the individual remain
               employed  to a date  that is on or after  the  first  day of said
               quarter.

           (2) A former Participant who is again designated as a Participant may
               not commence deferrals until January 1 of the Plan Year following
               the  designation of  participation,  and an election to defer for
               such Plan Year must be made prior to said January 1.

           (3) Except as provided in paragraph (4),  elections for the Plan Year
               commencing July 1, 1998 must be filed by June 30, 1998.

           (4) Notwithstanding  anything  in  this  Plan to the  contrary,  if a
               Participant was a participant in the Prior PSCo Plan or the Prior
               SPS Plan on June 30,  1998,  any  election  in effect  under such
               Prior Plan shall continue in effect for purposes of this Plan for
               the 1998 Plan Year,  and no new election  shall be allowed  under
               this Plan for that Plan  Year.  Any such  election  under a Prior
               Plan shall not apply to  Compensation  with respect to Plan Years
               commencing after 1998.

     (b)  The Participant may elect to defer either (i) any whole percent (in 10
          % increments) of  Compensation  payable with respect to the Plan Year,
          or (ii) any percent or dollar amount of  Compensation up to the amount
          required for the  Participant to receive the Company Credit under Sec.
          4.2. However,  the total deferrals during any Plan Year may not reduce
          the  Participant's  Compensation  payable during that Plan Year (after
          deduction  of the  deferrals  under this Plan) to less than the dollar
          amount in effect for that Plan Year under  Code  Section  414(q)(1)(B)
          ($80,000 for 1998).

     (c)  The deferred  compensation  credited under this section on behalf of a
          Participant  shall be  allocated  to the  Participant's  Cash  Account
          and/or  Directable Stock Account (as elected by the Participant) as of
          the date that the  Compensation  would otherwise have been paid to the
          Participant  in cash. Ile amount of Common Shares to be allocated to a
          Directable Stock Account shall be determined by dividing the credit by
          the average of the high and low sales prices of a Common  Share-on the
          New York Stock  Exchange on the business day  proceeding  the date the
          credit is made.

      (d)  The  Participant  must file  a  separate  deferral  election for each
           Plan Year with respect to which  deferrals  are to be made under this
           Plan.  An election  for a Plan Year shall become  irrevocable  on the
           first day of that year, subject to subsection (e). Elections will not
           carry over into  subsequent  Plan Years.  However,  an election for a
           particular Plan Year shall apply to all Compensation  with respect to
           that Plan Year,  including  incentive bonuses or other amounts earned
           during that year but paid in subsequent Plan Years.

      (e) Notwithstanding the foregoing provisions of this section:

           (1) All deferrals by a Participant shall cease as of (i) the date the
               Participant  receives a hardship  withdrawal  under any qualified
               defined   contribution   plan  subject  to  Code  Section  401(k)
               maintained by the Company or any of its affiliates which requires
               that  deferrals  be  suspended  for  a  certain  period  of  Lime
               following  such  withdrawal,  or (ii) the  date  the  Participant
               receives a withdrawal from this Plan for severe financial

                                           -6-


               hardship  due  to an  unforeseeable  emergency  under  Sec.  5.5.
               Deferrals  under this section may not recommence  until the first
               day of the second Plan Year  beginning  after the date  deferrals
               ceased  under the  previous  sentence,  and no further  deferrals
               shall be made from  Compensation with respect to Plan Years prior
               to said second Plan Year.

           (2) The Committee may in its sole  discretion  cancel a Participant's
               deferral election for the current Plan Year (and for Compensation
               not yet paid with  respect to any  previous  Plan Years) upon the
               request of a  Participant  if the  Committee  determines  that an
               event has occurred which would make the Participant  eligible for
               a   withdrawal   for  severe   financial   hardship   due  to  an
               unforeseeable  emergency  under Sec.  5.5.  Deferrals  under this
               section may not recommence until the first day of the second Plan
               Year beginning after the date deferrals ceased under the previous
               sentence,   and  no   further   deferrals   shall  be  made  from
               Compensation with respect to Plan Years prior to said second Plan
               Year. The Participant may request that deferrals cease under this
               paragraph  whether or not the  Participant  requests a withdrawal
               under Sec. 5.5.

     Sec.  4.2  Company  Credits.  Subject to the  Committee's  discretion,  the
Nondirectable  Stock Account of each eligible  Participant  will be credited for
each Plan Year with a Company  Credit  representing  a number of Common  Shares,
determined as follows:

      (a)  The  Company  Credit  for a Plan  Year  will be equal  to the  amount
           determined  under  paragraph  (1) minus the amount  determined  under
           paragraph (2), with the result divided by the amount determined under
           paragraph  (3),  and with the result  then  rounded  to four  decimal
           places, as follows:

           (1) A dollar  amount  equal to 50 % of the  smaller of (i) the sum of
               the amount of Base.  Salary the  Participant  deferred under this
               Plan  for  the   Plan   Year   and  the   Participant's   pre-tax
               contributions  to the Savings Plan for the Plan Year,  or (h) 8 %
               of the Participant's  "compensation" for the Plan Year recognized
               by  the  Savings  Plan  for  purposes  of  determining   matching
               contributions.  under  that Plan (but  disregarding  the limit on
               such compensation under Code Section 401(a)(17));

           (2) The dollar amount of matching  contributions actually made to the
               Savings Plan for the Participant for the Plan Year; divided by

           (3) The average of the high and low sale prices of a Common  Share on
               the New York Stock  Exchange on the  business day  preceding  the
               date the matching contribution is made to the Savings Plan.

      (b)  Notwithstanding  subsection  (a),  a  Participant  will  receive  the
           Company Credit for a Plan Year only if the  Participant  participates
           in the Savings  Plan and makes the maximum  dollar  amount of pre-tax
           contribution permitted by the Savings Plan for that year.

      (c)  The Company Credit for an eligible  Participant  for a Plan Year will
           be allocated to the Participant's  Nondirectable Stock Account on the
           date the  matching  contribution  for such Plan Year is (or would be)
           made under the Savings Plan.

                                           -7-





      (d)  Each Participant's Nondirectable Stock Account shall also be credited
           with any Common Shares  deferred under any annual  incentive plan, or
           other plan that may be established  by the Company,  for that portion
           of the award which is otherwise payable in Common Shares. Such credit
           shall  occur as of the date such  shares  would  otherwise  have been
           distributed to the Participant.

      (e)  Notwithstanding  the  foregoing,  the Company  Credits for the period
           from July I to  December  31, 1998 under this  Section  will be based
           only on compensation and contributions during that period.

Participant  will be adjusted as of each  Valuation  Date to reflect  Investment
Credits,  deferrals  allocated to the Account  under Sec. 4. 1, Company  Credits

of Stock Accounts under Sec. 4.5, and distributions  from Accounts under Article

      (a)  Investment  Credits  on  each  Cash  Account  will  be  based  on the
           investment  index or indexes  selected by the  Participant to measure
           the  deemed  rate of  investment  return  on his or her  Account  The
           investment  indexes will be the same as the investment  options under
           the  Savings  Plan  (except  the NCE  Stock  Fund),  and  such  other
           investment  options as the Committee  makes available under this Plan
           from time to time.

      (b)  A Participant may file separate investment elections for the existing
           Cash  Account  balance  and for future  amounts to be credited to the
           Participant's  Cash Account  and/or  Directable  Stock  Account.  The
           Participant may also elect to have amounts transferred between his or
           her Cash Account and Directable  Stock Account.  The amount of Common
           Shares to be credited upon a transfer into a Directable Stock Account
           shall be determined as provided in Sec. 4. 1 (c).

      (c)  All investment  elections  shall be in accordance with such rules and
           regulations  as the Committee may  establish  from time to time.  The

           Accounts as the  Committee  determines  in its sole  discretion  will
           reasonably  reflect the period of time amounts were  credited to each
           Account.

      (d)  Notwithstanding the foregoing,  the Committee may modify or disregard
           an  investment  election  filed by a  Participant  to the  extent the
           Committee determines that such action is necessary to comply with the
           terms  of this  Plan or to  avoid  adverse  tax  consequences  to the
           Participant or the Participating Employers.

      (e)  Notwithstanding   anything   in  the  Plan  to  the   contrary,   the
           Participating  Employers shall be under no obligation to purchase any
           investments  used for determining  Investment  Credits or to purchase
           Common  Shares.  The  investment  indexes and Common  Shares are used
           solely for the recordkeeping purpose of measuring gains and losses on
           each Participant's  Accounts,  and the Participant's Accounts are not
           actually being invested in the indexes or in Common Shares.

     Sec. 4.4 Dividends on Common  Shares.  Each  Participant's  Stock  Accounts
shall be credited as of each  dividend  payment date for Common Shares with that

           shares  (including  fractional  shares,  carried out to four  decimal
           places)  credited to each Stock Account of such Participant as of the
           record date for payment of such dividend, by

      (b)  the  average of the high and low sale price of a Common  Share on the
           New  York  Stock  Exchange  on the  day  preceding  the  date of such
           dividend payment.

      Sec. 4.5  Adjustment of Stock Accounts for Splits,  Dividends,  Etc In the
event of any change in the outstanding Common Shares of the Company by reason of
any share dividend or split, recapitalization,  merger, consolidation, spin-off,
reorganization,  combination  or  exchange  of Common  Shares  or other  similar
corporate change, the Committee shall make appropriate  adjustment in the number
of the Common Shares in the Participants' Stock Accounts.

Nondirectable Stock Account.

     Sec. 5.2 Manner of Payment. The balance in a Participant's Cash Account and
the value of whole and  fractional  shares in the  Participant's  Stock Accounts
shall be paid in cash in a single lump sum payment.

      Sec.  5.3 Amount of  Payment.  The amount of cash to be  distributed  to a
Participant with respect to the Participant's  Cash Account shall be the balance
of such account as of the end of the month prior to the distribution. The amount
of cash to be  distributed  to a Participant  with respect to the  Participant's
Stock Accounts shall be the number of shares credited to such Accounts as of the
end of the month prior to the distribution multiplied by the average of the high
and low sales price of a Common Share on the New York Stock Exchange on the last
trading day of the month prior to the distribution.

     Sec. 5.4 Beneficiary Designation. Each Participant shall have the right, at
any time, to designate any person or persons as Beneficiary or  Beneficiaries to

Accounts. Each Participant shall have the right to change his or her Beneficiary

designation at any time. Each  Beneficiary  designation  shall become effective
only when filed in writing with the Committee during the Participant's life on a
form  prescribed  by the  Committee.  The  rights of each  Beneficiary  shall be
subject to the terms and  conditions  specified on the  designation  form to the
extent  consistent  with  the  terms  of the  Plan.  If a  Participant  fails to
designate a Beneficiary as provided  above,  or if all designated  Beneficiaries
predecease the  Participant,  then the  Beneficiary  shall be the  Participant's
estate.

      Sec. 5.5 Distributions for Severe Financial Hardship.  Notwithstanding the
foregoing  sections of this Article V, the Committee in its sole  discretion may
approve a request  by a  Participant  for a  withdrawal  from the  Participant's
deferred amounts due to an unforeseeable emergency. An "unforeseeable emergency"
is severe  financial  hardship to the  Participant  resulting  from a sudden and
unexpected  illness or accident of the Participant or of a dependent (as defined
in Code Sec. 152(a) of the Participant,  loss of the Participant's  property due
to casualty,  or other similar  extraordinary  and  unforeseeable  circumstances
caused  by an  event  beyond  the  control  of  the  Participant.  Unforeseeable
emergencies  specifically  do not  include-  the need to pay for  education of a
Participant's  child or the desire to purchase a home. Any such early withdrawal
approved by the Committee may not exceed the amount reasonably necessary to meet
the  emergency.  Payment may not be made to the ixtent that such  hardship is or
may be relieved by any of the following means:

      (a)  Through reimbursement or compensation by insurance or otherwise.

      (b)  By  liquidation  of  the  Participant's  assets,  to the  extent  the
           liquidation  of such assets would not itself  cause severe  financial
           hardship.

      (c) By cessation of deferrals under the Plan.

     Sec. 5.6 Modification of Elections for Tax Considerations.  Notwithstanding
anything to the contrary in the  foregoing  sections of this Article V or in any
election filed by a Participant:

      (a)  If the  Committee  determines,  based on advice of legal counsel or a
           final  determination  by the Internal  Revenue  Service or a court of
           competent jurisdiction, that a Participant or Beneficiary may be held
           to be in  constructive  receipt  of  benefits  under  this  Plan  and
           required to recognize such, benefit  immediately or retroactively for
           income tax purposes,  the Committee may in its sole  discretion  take
           either of the following actions:

           (1) Distribute  the entire  affected  benefit in a single lump sum as
               soon as administratively feasible.

           (2) Take written action modifying the  Participant's  election and/or
               the terms of the Plan  (retroactively,  if necessary) in a manner
               that will eliminate the allegation of constructive  receipt while
               at the same time carrying out the  Participant's  original intent
               to the extent possible.

      (b)  The Committee may postpone any payment to be made to a Participant or
           Beneficiary  until a  subsequent  fiscal  year  of the  Participating
           Employers to the extent the  Committee  determines to be necessary in
           order to avoid the loss of an income tax deduction under Code Section
           162(m).

      Sec. 5.7 Withholding and Taxes. The benefits payable under this Plan shall

Participant's  Beneficiary  hereunder by any amounts the Participant owes to the
