Exhibit 10.21 (b)


                            EQUITABLE RESOURCES, INC.

                               Board of Directors
                         Deferred Compensation Agreement



      THIS  AGREEMENT,  made and executed this 30th day of December,  1988, by
and between Equitable Resources,  Inc., herein designated as "Equitable",  and
Malcolm M. Prine Christiano, herein designated as the "Participant."


                                   WITNESSETH:

      WHEREAS, the Participant is currently a member of the Board of
Directors of Equitable as a Director or an Advisory Director; and

      WHEREAS,  Equitable and the Participant  desire to defer all of the fees
arising from the above-stated relationship.

      NOW, THEREFORE, the parties hereby agree as follows:


Section 1 - Account

      1.1) Effective January 1, 1989, the Participant  herein elects to defer,
under the terms of this Agreement, all compensation earned for his/her service
as a Director or an Advisory Director of Equitable for the calendar year 1989.

      1.2)  Equitable  shall  establish  a  bookkeeping  account,  hereinafter
referred to as the  "Account",  and shall credit to the Account the amounts of
the deferred fees.

      1.3)  Interest  shall be credited to the  Account  monthly.  The rate of
interest shall be the same as the yield for 30-day  Treasury Bills  applicable
to the first day of such month.

Section 2 - Payment

      2.1) All amounts  credited to the  Account on the  Participant's  behalf
shall  be  payable  in  one  lump  sum by  Equitable  to  the  Participant  on
_________________  (date  selected by the  Participant)  but in no event later
than  sixty  (60) days after the  Participant  ceases to be a  Director  or an
Advisory Director of Equitable.

      2.2) In the event of the death of the Participant, such payment shall be
made  to  the  Participant's  beneficiary.  For  purposes  of  the  Agreement,
"beneficiary"  means any person(s) or trust(s) or combination  of these,  last
designated  by  the  Participant  to  receive  benefits  provided  under  this
Agreement.  Such  designation  shall be in writing filed with the Compensation
Committee of the Board of Directors (the  "Committee")  and shall be revocable
at any time through written instrument  similarly filed without consent of any
beneficiary.  In the absence of any designation,  the beneficiary shall be the
Participant's spouse, if surviving,  otherwise,  all amounts payable hereunder
shall be delivered by Equitable to the  executors  and  administrators  of the
Participant's estate for administration as a part thereof.

      2.3) For financial  reasons,  the Participant may apply to the Committee
for  withdrawal  from the  Agreement  prior to the  Payment  Date.  Such early
withdrawal  shall lie within the absolute  discretion of the  Committee.  Upon
approval from the  Committee,  and within  fifteen (15) days  thereafter,  the
Participant  will be  deemed  to  have  withdrawn  from  the  Agreement  and a
distribution,  in the amount  necessary,  will be made in a one-time  payment.
Amounts  still  payable  to the  Participant  after  the  application  of this
Paragraph 2.3 shall be  distributed  pursuant to the  foregoing  Paragraphs of
this Section 2.

Section 3 - Miscellaneous Provisions

      3.1) Nothing contained in this Agreement and no action taken pursuant to
the  provisions  of this  Agreement  shall  create or be construed to create a
trust of any kind,  or a  fiduciary  relationship  between  Equitable  and the
Participant,  his/her  designated  beneficiary  or any other person.  Any fees
deferred  under  the  provisions  of this  Agreement  shall  continue  for all
purposes to be a part of the general  funds of  Equitable.  To the extent that
any person  acquires  a right to receive  payment  from  Equitable  under this
Agreement,  such  right  shall be no greater  than the right of any  unsecured
general creditor of Equitable.

     3.2) The right of the  Participant  or any other person to the payment of
deferred fees under this Agreement shall not be assigned, transferred, pledged
or encumbered except by will or by the laws of descent and distribution.

      3.3) If the Committee  shall find that any person to whom any payment is
payable under this Agreement is unable to care for his/her  affairs because of
illness or  accident,  or is a minor,  any  payment  due (unless a prior claim
therefor shall have been made by a duly appointed guardian, committee or other
legal representative) may be paid to the spouse, child, a parent, or a brother
or sister,  or to any person deemed by the Committee to have incurred  expense
for such person otherwise entitled to payment,  in such manner and proportions
as the Committee may determine. Any such payment shall be a complete discharge
of the liabilities of Equitable under this Agreement.

      3.4) Nothing  contained herein shall be construed as conferring upon the
Participant  the right to continue in the service of  Equitable as a member of
the Board of Directors.

      3.5) This  Agreement  shall be binding  upon and inure to the benefit of
Equitable,  its successors and assigns and the  Participant and his/her heirs,
executors, administrators and legal representatives.

      3.6)  Equitable  may  terminate  this  Plan  at  any  time.   Upon  such
termination, the Committee shall dispose of any benefits of the Participant as
provided in Section 2.

      Equitable  may also  amend  the  provisions  of this  Plan at any  time;
provided,   however,  that  no  amendment  shall  affect  the  rights  of  the
Participant,  or his/her beneficiaries,  to the receipt of payment of benefits
to the extent of any compensation deferred before the time of the amendment.

      This Agreement shall terminate when the payment due under this Agreement
is made.

      3.7) This Agreement  shall be construed in accordance  with and governed
by the laws of the Commonwealth of Pennsylvania.

Section 4 - Committee

      4.1) The Committee's  interpretation  and construction of the Agreement,
and the actions  thereunder,  including the amount or recipient of the payment
to be made  therefrom,  shall be binding and conclusive on all persons for all
purposes.  The  Committee  members  shall not be liable to any  person for any
action  taken  or  omitted  in   connection   with  the   interpretation   and
administration  of this  Agreement  unless  attributable  to his  own  willful
misconduct or lack of good faith.

      IN WITNESS  WHEREOF,  Equitable has caused this Agreement to be executed
by its duly  authorized  officers and the Participant has hereunto set his/her
hand as of the date first above written.
