Exhibit 10.21

DIRECTORS’ COMPENSATION

The Corporate Governance Committee of the Board of Directors discharges the
Board’s responsibilities relating to compensation of directors.  Compensation of
directors is reviewed by the Corporate Governance Committee annually at its
April meeting and is approved by the Board.  No compensation is paid to employee
directors for their service as directors.

The Corporate Governance Committee has engaged Towers, Perrin, Forster & Crosby,
Inc. (“Towers Perrin”), an external human resources consulting firm, to conduct
an annual review of the total compensation for outside directors.  Specifically,
retainer fees, meeting fees, stock-based long-term incentives and insurance were
evaluated using, as the competitive benchmark, levels of total compensation paid
to directors of 30 energy companies (including the 29 companies constituting the
Long Term Incentive Peer Group), 20 general industry companies of comparable
revenue and equity capitalization size and 14 companies located in the company’s
geographic area or of other relevance.  Set forth below is the 2006 compensation
of the company’s non-employee directors.

CASH COMPENSATION

·      An annual cash retainer of $30,000 is paid on a quarterly basis.  The
level of retainer was increased in 2006 from $24,000 to be competitive with
market peers.

·      The cash meeting fee is $1,500 for each Board and committee meeting
attended in person.  If a director participates in a meeting by telephone, the
meeting fee is $750.  An additional $500 is paid to each committee chair ($1,500
for the Audit Committee Chair) for each meeting of his or her committee that the
chair attends.

EQUITY-BASED COMPENSATION

·      In 2003, the company began granting to each director stock units that
vested upon award and that are payable on a deferred basis under the directors’
deferred compensation plans.  In 2006, a grant of 2,000 deferred stock units was
awarded to each non-employee director.  The deferred stock units are awarded by
the Board annually at the April Board meeting upon the recommendation of the
Corporate Governance Committee.  Each deferred stock unit is equal in value to
one share of company common stock, but does not have voting rights.  Dividends
are credited quarterly in the form of additional stock units.  The value of the
stock units will be paid in cash on the earlier of the director’s death or
termination of service as a director.

·      The non-employee directors are subject to stock ownership guidelines
which require them to hold shares (or share equivalents, including deferred
stock units) with a value equal to at least two times the annual cash retainer. 
Under the guidelines, directors have up to two years to acquire a sufficient
number of shares (or share equivalents, including deferred stock units) to meet
this requirement.  All of the company’s non-employee directors meet this share
ownership requirement.

DEFERRED COMPENSATION

·      The company has a deferred compensation plan for non-employee directors. 
In addition to the automatic deferral of stock units awarded, non-employee
directors may elect to defer up to 100% of their annual retainer and fees into
the 2005 Directors’ Deferred Compensation Plan and receive an investment return
on the deferred funds as if the funds were invested in company stock or
permitted mutual funds.  Prior to the deferral, plan participants must
irrevocably elect to receive the deferred funds either in a lump sum or in equal
installments.  Distributions commence no earlier than 30 days following
termination of service as a director.  The directors’ deferred compensation
accounts are unsecured obligations of the company.  Ms. Jeremiah and Mr. Miles
deferred fees under the plan in 2006, and they and other directors have
participated in prior years.  The pre-existing Directors’ Deferred Compensation
Plan continues to operate for the sole purpose of administering amounts vested
under the plan on or prior to December 31, 2004.

Other

·      To further the company’s support for charitable giving, all directors are
eligible to participate in the Matching Gifts Program of the Equitable Resources
Foundation, Inc. (the “Equitable Foundation”) on the same terms as company
employees.  Under this program, the Equitable Foundation will match gifts of at
least $100 made by the director to eligible charities, up to an aggregate total
of $10,000 in any calendar year.

·      Non-employee directors who joined the Board prior to May 25, 1999 may
designate a civic, charitable or educational organization as beneficiary of a
$500,000 gift funded by a life insurance policy purchased by Equitable
Resources.  The directors do not receive any financial benefit from this program
because the charitable deductions accrue solely to the company.

·      The company reimburses directors for their travel and related expenses in
connection with attending Board meetings and Board-related activities.  The
company also provides non-employee directors with $20,000 of life insurance and
$250,000 of travel accident insurance while traveling on business for the
company.
