ELECTION OF DIRECTORS

Common Shareholders are entitled to cumulative voting for directors. Each
Common Shareholder may cast a number of votes equal to the number of Common
Shares owned multiplied by the number of directors to be elected. Votes may be
cast for a single nominee or distributed among nominees.

The Articles of Incorporation provide for three classes of directors. The
term of office of each class is three years and the term of one class expires
each year. The Bylaws provide for a Board with eleven members. Approximately
one-third of the Board will be elected at each Annual Meeting of Shareholders.
A vacancy can be filled by a vote of the shareholders or by the Board.

Four directors are to be elected at this Annual Meeting. Each of the four
persons receiving the highest number of votes will be elected. Proxies are
being solicited to vote for the election of the following four persons:

John T. Ferris
Michael O. Frazer
Frederick S. Moore
Edith A. Stotler

The Board does not expect that any nominee will become unavailable. Should
that occur, however, proxies will be voted for another person selected by the
Board.

The persons named in the enclosed proxy reserve the right to vote proxies
cumulatively, but do not intend to do so unless other persons are nominated at
the meeting. As shown on the proxy, shareholders may direct that their shares
be voted for less than all four of the above-named nominees.

INCREASE IN NUMBER OF AUTHORIZED PREFERRED SHARES
AND CHANGE IN ARTICLES OF INCORPORATION

The Company proposes to amend its Articles of Incorporation in order to:

(1) increase the number of authorized shares of Preferred Stock ("Preferred
Shares") from the existing 500,000 authorized shares to 4,500,000 authorized
shares; and

(2) allow the Board of Directors to determine the relative rights and
preferences of each series of Preferred Shares.

The Company has embarked on a new strategic plan to more aggressively grow
its businesses through acquisitions. In recognition of this strategic plan, in
1999 Shareholders approved an increase in the number of authorized Common Shares
to 40,000,000. The Company believes that increasing the number of authorized
Preferred Shares will facilitate growing its business - especially through
acquisitions. For example, to finance an acquisition, the Company may deem it
appropriate to issue Preferred Shares possibly in conjunction with Common Shares
and/or debt.

In light of these circumstances, the Board of Directors believes it would
be in the best interest of the Company to increase the authorized number of
Preferred Shares, thereby assuring that an ample number of authorized shares
will be available for issuance in order to facilitate its strategic goals. The
---
Company currently has no definitive plans to issue Preferred Shares, but would
- --------------------------------------------------------------------------------
issue such shares in the future if it is financially advantageous to do so.
- -------------------------------------------------------------------------------

Currently, there are 500,000 Preferred Shares authorized, but none
outstanding. The Articles of Incorporation presently provide the Board of
Directors with discretion to determine the relative rights and preferences of
each series of Preferred Shares, except for certain items. These items limit:

(1) the timing of the payment of dividends (the Board currently has
discretion to establish the amount of dividends);

(2) the Company's ability to repurchase Common Shares in certain
circumstances;

(3) the Company's ability to repurchase or redeem some Preferred Shares
without repurchasing or redeeming all of them;

(4) the Company's ability to give preference on liquidation to any one
series of Preferred Shares over another series of Preferred Shares;

(5) the voting rights of Preferred Shares.

As a result of the proposed Amendment, these restrictions on Board
discretion will be removed to provide additional financial flexibility and
advantages to the Company. The authorized Preferred Shares would be issuable at
the Board's discretion, normally without further stockholder action, for any
proper corporate purposes.

The Company's Board of Directors and management have no definitive plans
for the issuance of any of the presently authorized and unissued Preferred
Shares or of the additional shares to be authorized. Rather, it is the
intention of the Board of Directors and management to hold such authorized and
unissued Preferred Shares in reserve for such corporate needs as may develop.
Thus, it is not possible to describe the specific terms of any series of
Preferred Shares at this time. If Common Shareholders approve the proposal, the
Board of Directors may determine all the terms of any series of Preferred Shares
including dividend rates, voting rights, prices for redemption by the Company,
conversion prices or rates, and similar matters.

No Shareholder of the Company has any preemptive rights to subscribe for or
to purchase any of the authorized and unissued Preferred Shares including the
additional shares to be authorized.

The financial statements of the Company as well as management's discussion
and analysis of financial condition and results of operations, included in the
1999 Annual Report to Shareholders, are incorporated by reference herein.

The affirmative vote of the holders of at least a majority of Common Shares
of the Company outstanding as of the Record Date (February 22, 2000), is
required to adopt the amendment.

THE BOARD OF DIRECTORS AND MANAGEMENT RECOMMEND THAT THE COMMON
SHAREHOLDERS VOTE FOR THE PROPOSAL TO INCREASE THE NUMBER OF AUTHORIZED
PREFERRED SHARES AND AMEND THE ARTICLES OF INCORPORATION.

EMPLOYMENT AND RELATED AGREEMENTS

Mr. Johnson's employment agreement, which is for a term of five years,
provides for a severance payment if the Company terminates his employment other
than for "cause" or "disability" or if Mr. Johnson resigns due to a required
relocation of personal residence or a demotion in position, authority, etc. The
severance amount will equal Mr. Johnson's annual salary. The Company will also
continue insurance and similar benefit plans for twelve months, subject to
certain limitations.

Mr. Johnson's change-of-control employment agreement has parallel
provisions to his employment agreement except severance amount equals 2.99 times
his annual base salary and average bonus. All named executive officers have
change-of-control employment agreements parallel to Mr. Johnson's. The
severance amount is subject to reduction to the extent required in order to
avoid unfavorable tax consequences to the Company and the executive officers.

PENSION PLAN

The following table sets forth the estimated annual benefits payable at
normal retirement age (65) under the Pension Plan based on the formula in effect
beginning January 1, 1999 described below. Only salary up to $160,000 is
counted for the Pension in 1999. This ceiling amount is set by law and will
increase over time.

At age 65, a participant can receive an annual pension equal to 1.75% of
his average annual base salary for any consecutive three years multiplied by
years of credited service after October 31, 1970 (but before 1999) plus 1.4% of
his average five-year adjusted compensation multiplied by years of credited
service after 1998. If greater, a participant will receive an annual pension
equal to 1.4% of his average five-year adjusted compensation multiplied by all
his credited years of service. Adjusted compensation includes salary and bonus,
but excludes fringe benefits, expense reimbursements, bonuses to pay taxes on
fringe benefits, and similar types of compensation. These benefits are not
subject to any deduction for Social Security or other offset.

As of January 1, 2000, credited service was as follows: Messrs. Johnson
and Porter each had 3 years, Mr. Hatches had 2 years, and Messrs. Cifolelli and
Coppola each had 1 year.

SUPPLEMENTAL PENSION

[Each named executive officer above is a party to an Executive Security
Agreement which provides for additional retirement benefits for 15 years. If
the executive officer retires at age 65, yearly payments will equal 50% of his
last base salary. An executive officer retiring before age 65, but after 55,
can receive from 30% (age 55) to 48% (age 64) of base salary.

This Executive Security Agreement, effective in the first quarter of 1998,
replaces certain benefits previously provided. These replaced benefits include
bonuses for a life insurance policy disclosed in the Bonus column of the above
Summary Compensation Table. Also replaced is the term life insurance reflected
in the All Other Compensation column of that Table.]

or if the Board approves changes:

This Executive Security Agreement, effective in the first quarter of 1998
and amended in the first quarter of 2000, replaced certain benefits previously
provided. These replaced benefits include bonuses for a life insurance policy
disclosed in the Bonus column of the above Summary Compensation Table. Also
replaced was the term life insurance reflected in the All Other Compensation
column of that Table. The amended Executive Security Agreement provides pension
benefits which could not be provided by the Pension Plan because of the limit on
compensation ($170,000 in 2000) which can be considered by the Pension Plan. In
addition, the amended Executive Security Agreement provides protection for the
named officers in the event of a Change in Control by requiring the funding of a
Rabbi Trust (under certain circumstances) and early vesting of benefits (under
other circumstances).]

DIRECTOR COMPENSATION

Annual Compensation
--------------------

A portion of Mr. Johnson's base compensation during 1999 was for service as
Chairman of the Board.

For their services on the Board, non-employee directors are paid a retainer
of $1,000 per month. The Chairmen of the Audit, Compensation, Finance, and
Nominating and Corporate Governance Committees each receive an additional
retainer of $200 per month. The Lead Director receives an additional retainer
$1,250 per month. Each non-employee director receives $700 per meeting
attended. The Chairmen of the Audit, Compensation, Finance, and Nominating and
Corporate Governance Committees each receive an additional $175 per meeting
chaired. Directors are reimbursed for expenses incurred in attending Board and
Committee meetings.

Non-employee directors who were members of the Board prior to 1996 may
participate in the Company's medical program. Directors who join the Board
after 1995 cannot participate in the medical program. Directors who do not
participate in the Company's medical program receive a grant of $3,500 worth of
Common Shares each year.

Non-employee directors also accrue $3,000 per year under a non-qualified
defined contribution plan, which is payable after leaving the Board. Interest
accrues at 8% per annum.

Deferred Compensation
----------------------

Under Deferred Compensation and Common Stock Purchase Agreements for
Outside Directors, directors' cash compensation may be deferred for each
upcoming year. If deferred, compensation accrues interest at the prime rate or
is invested in Common Shares with dividends reinvested through the dividend
reinvestment plan. Five directors deferred some or all cash compensation for
1999, which was used to purchase Common Shares. Six directors have chosen to
purchase Common Shares by deferring some or all cash compensation for 2000.

Stock Options
--------------

Each non-employee director also receives an annual grant of non-qualified
stock options exercisable at fair market value on date of grant to acquire 1,000
shares of Company Common Stock under the Long-Term Incentive Plan. Upon joining
the Board, new non-employee directors also receive such a grant. Thus, a
non-employee director joining the Board prior to the date options are granted to
all directors for the year will receive two grants within the same year.
However, no grant of stock options will be made to directors who are known to be
leaving the Board within six months after the grant date. Such stock options
become exercisable one-third each year for three years and expire ten years from
the date of grant.

Stock Ownership Guidelines
----------------------------

In 1999, the Board increased its stock ownership guidelines for
non-employee directors. Each non-employee director is expected to own, within
five years, Company Common Stock equal in value to five times the director's
annual retainer.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

Membership on the Compensation Committee ("Committee") for 1999 was as
follows: Ms. Stotler and Messrs. Ferris, Klein and Thomason. None of these
Committee members are Company officers or served on other Boards with Company
officers. None of the Company's executive officers served on a board of
directors of a company which had an employee serving on the Company's Board of
Directors.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

The Compensation Committee ("Committee") is responsible for recommending to
the full Board the compensation of Executive Officers. The Committee is
composed of four non-employee directors. The Committee intends to provide
salary and other non-incentive compensation for an executive, equal to the
average of that paid to executives with similar experience, responsibilities and
authority in a peer group including other utility companies (Peer Group).
Incentive plans provide each executive with an opportunity for above-average
total compensation, if financial targets or other performance goals are
exceeded.

All base salaries of officers, including those shown in the "Salary" column
of the above Compensation Table, were approved by the Committee.

Under the Company's Short-Term Incentive Plan, Mr. Johnson is eligible for
a cash bonus of up to 40% of his base salary if the Company meets target
earnings for the year. If the Company achieves 108% or more of target earnings,
Mr. Johnson is eligible for a cash bonus of up to a maximum of 72% of his base
salary. Bonuses for Mr. Johnson are based on the Company's performance (80%)
and on his individual performance (20%). Bonuses for other Executive Officers
range from 25% of base salary if the Company achieves target earnings to 63% of
base salary if the Company achieves at least 108% of target earnings. Bonuses
for other Executive Officers are based on the Company's performance, their
individual performance and a discretionary amount.

Also, the Board may make incentive awards in lieu of bonuses under the
Short-Term Incentive Plan in unusual circumstances. Only unusual circumstances
outside the control of executive officers are considered. Such circumstances
may include, for example, significantly warmer than normal weather.

In addition, under the Long-Term Incentive Plan, Mr. Johnson may be granted
stock options for up to 30,000 shares each year if the Company's performance and
his performance are outstanding. The Long-Term Incentive Plan was approved by
the shareholders at the Annual Meeting held April 15, 1997. Awards to Mr.
Johnson and other Executive Officers are based primarily on company performance.
However, business unit performance and individual performance are also
considered. Maximum awards of stock options to other Executive Officers range
from 5,250 to 10,500 shares.

Further detail regarding compensation is shown under "Compensation of
Directors and Executive Officers."

All decisions of the Committee regarding executive compensation are
reviewed by the full Board.
