                 ANNUALIZED THREE-YEAR TOTAL SHAREHOLDER RETURN
                                RELATIVE TO PEERS

THREE-YEAR AVERAGE RETURN ON CAPITAL (ROC) means the average of the Return on
Capital for the three fiscal years of the Performance Cycle.

RETURN ON CAPITAL means for any fiscal year, (i) the Company's Operating Profits
After Taxes divided by (ii) its Average Capital.

OPERATING PROFITS AFTER TAXES means, for the relevant fiscal year, the sum of
(i) Operating Income After Taxes and (ii) Qualified Tax Benefits.



OPERATING INCOME AFTER TAXES is the product of (a) the Company's operating
income minus short term interest expense and fees related to commercial paper
and lines of credit plus interest income and (b) one minus the Company's
marginal tax rate.

QUALIFIED TAX BENEFITS is identifiable tax credits that contribute to the
economic merits of a project or investment (e.g. wind power, oil and gas
production tax credits).

AVERAGE CAPITAL means, for the relevant fiscal year, the average of invested
capital (stockholders' equity plus long-term debt, including long-term debt
classified as short-term), determined by dividing (a) thirteen into (b) the sum
of (i) the invested capital balance at month end for each of the 12 months of
the relevant fiscal year and (ii) the month end balance of invested capital for
the month immediately preceding such fiscal year.

ANNUALIZED THREE-YEAR TOTAL SHAREHOLDER RETURN (TSR) means (a) taking the cubic
root of Total Shareholder Return and (b) subtracting one.

      Total Shareholder Return means the result of dividing (a) Ending Total
      Value by (b) Beginning Total Value.

      Ending Total Value means the product of (a) the Number of Shares On Ending
      Date multiplied by (b) the closing share price on the last Trading Day of
      the Performance Cycle.

      Beginning Total Value means the closing value of one share on the last
      Trading Day of the month immediately preceding the beginning date of the
      Performance Cycle.

      Number of Shares On Ending Date means the number of shares, inclusive of
      dividend reinvestment, on the last day of the Performance Cycle. Number of
      Shares on Ending Date is calculated assuming one share is owned at the
      beginning of the Performance Cycle, to which amount is added, in any month
      in which a dividend payment occurs (determined by the date a stock goes
      "ex-dividend"), the amount of additional shares that could be purchased by
      dividing (a) the ending month share price into (b) the product of (i) the
      amount of shares owned (inclusive of any prior dividend reinvestments) at
      the beginning of the month and (ii) the dividend rate per share. Share
      prices are determined by the closing price on the last Trading Day of the
      month.

      Trading Day means any day that the New York Stock Exchange is open for
      business.



ANNUALIZED THREE-YEAR TOTAL SHAREHOLDER RETURN RELATIVE TO PEERS will be Peoples
Energy's Annualized Three - Year Total Shareholder Return compared against the

Should a situation arise where it would no longer be possible to calculate Total
Shareholder Return for a Peer Group company (e.g. stock de-listing, acquisition)
then a suitable replacement firm will be added to the listing of Peer Group
companies, such replacement firm subject to approval of the Committee. In the
event no suitable replacement firm can be identified, then the
percentile-ranking table will be adjusted to reflect the remaining number of
firms in a manner consistent with current percentile-ranking table.

COMPUTATION OF FINAL PERCENT OF GRANT PAID: Since the matrix is not linear,
proration will occur in some cases. Base Value will be the pay-out box value
that corresponds to ROC and TSR levels immediately below those achieved.
Proration will occur when that base value is above zero. From the Base Value,
the ROC prorated value will be calculated by taking a proration between that ROC
level and the next higher ROC level. Then the TSR prorated value will be
computed in a like manner (starting from the Base Value). The two prorated
values will be added to the base value to get the percent of grant paid. If the
base value is zero, no proration will occur.
