                                PROXY STATEMENT

     The enclosed proxy is solicited by the Board of Directors of SEMCO Energy,
Inc. (the Company) for use at the Annual Meeting of Common Shareholders on
Tuesday, April 15, 2003, at 10:00 a.m. (EDT), to be held at the McMorran
Auditorium, 701 McMorran Boulevard, Port Huron, Michigan, and any adjournments
thereof. These proxy materials are being mailed to shareholders on or about
March 10, 2003.

     A Shareholder giving the enclosed proxy may revoke it any time before it
is voted by submitting a subsequent proxy (by telephone, internet or mail), by
written notice to the Corporate Secretary of the Company, or by voting in
person at the meeting.

     The Company will bear the cost of soliciting proxies, including charges
and expenses of brokerage firms and others for forwarding proxy material to
beneficial owners of stock. In addition to mailings, proxies may be solicited
by personal interview, telephone or otherwise by employees. The Company may
also retain outside organizations to assist in soliciting proxies.

     A copy of the Company's 2002 Annual Report is enclosed.


           ELECTRONIC DELIVERY OF PROXY STATEMENT AND ANNUAL REPORT

     This proxy statement and the 2002 annual report are available at
www.proxyvote.com. Most shareholders can elect to view future proxy statements
and annual reports over the Internet instead of receiving paper copies in the
mail.

     Shareholders of record (see question below: "What is the difference
between holding shares as a shareholder of record and as a beneficial owner?")
may choose this option to save the Company the cost of producing and mailing
these documents by:

     o following the instructions provided when you vote over the Internet; or
     o writing to:

          SEMCO Energy, Inc. Investor Relations
          28470 13 Mile Road, Suite 300
          Farmington Hills, MI 48334

     Shareholders of record who choose to view future proxy statements and
annual reports over the Internet will receive an e-mail message next year
containing the Internet address to use to access the Company's proxy statement
and annual report. The e-mail will also include instructions for voting over
the Internet. Electronic delivery instructions will remain in effect until
revoked in writing. It is not necessary to elect Internet access each year.


                                       3





     Beneficial owners (see question below: "What is the difference between
holding shares as a shareholder of record and as a beneficial owner?") should
refer to information provided by their broker, bank or nominee for instructions
on how to elect to view the Company's future proxy statements and annual
reports over the Internet if their broker or nominee participates in the
service. Beneficial owners who choose electronic delivery will receive an
e-mail message next year containing the Internet address to use to access the
Company's proxy statement and annual report.


                           HOUSEHOLDING INFORMATION

Q:   WHAT IS "HOUSEHOLDING"?
A:   We have adopted a procedure called "householding", which has been approved
     by the Securities and Exchange Commission. Under this procedure, a single
     copy of the annual report and proxy statement will be sent to any household
     at which two or more shareholders reside if they appear to be members of
     the same family, unless one of the shareholders at that address notifies us
     that they wish to receive individual copies. This procedure reduces our
     printing costs and fees.

     Shareholders who participate in householding will continue to receive
     separate proxy cards.

     Householding will not affect dividend check mailings in any way.

     In future years, if a single copy of the annual report and proxy statement
     is delivered to an address that you share with another stockholder, at
     your request, we will promptly deliver a separate copy.

Q:   HOW DO I WITHHOLD MY CONSENT TO THE HOUSEHOLDING PROGRAM?
A:   If you are a shareholder of record and share an address and last name with
     one or more other shareholders of record, and you wish to continue to
     receive separate annual reports, proxy statements and other disclosure
     documents, you must withhold your consent by checking the appropriate box
     on the enclosed proxy card and returning it by mail in the enclosed
     envelope. Even if you vote by telephone or Internet, the enclosed proxy
     card must be returned and marked appropriately to withhold your consent to
     householding.

     If you do not return the proxy card to withhold your consent to the
     householding program, you may revoke your consent at a future date. Please
     contact Automatic Data Processing, Inc. ("ADP"), either by calling toll
     free (800) 542-1061 or by writing to ADP, Householding Department, 51
     Mercedes Way, Edgewood, New York 11717. You will be removed from the
     householding program within 30 days of receipt of the revocation of your
     consent.

     If you are receiving multiple copies of annual reports and proxy
     statements at an address shared with another shareholder, you may also
     contact ADP to participate in the householding program.

     A number of brokerage firms have instituted householding. If you are a
     beneficial owner (see question below: "What is the difference between
     holding shares as a shareholder of record and as a beneficial owner?"),
     please contact your broker, bank or nominee to request information about
     householding.

                      STOCK OUTSTANDING AND VOTING RIGHTS

ANSWERS TO COMMONLY ASKED QUESTIONS
RELATING TO STOCK OUTSTANDING AND VOTING RIGHTS
- -----------------------------------------------

Q:   WHO IS ENTITLED TO VOTE?
A:   Only Common Shareholders of record at the close of business on February 18,
     2003 (the record date) may vote in person or by proxy at the meeting.

Q:   WHAT SHARES MAY I VOTE?
A.   You may vote all shares you owned as of the record date. These include (1)
     shares owned directly in your name as shareholder of record and (2) shares
     held for you as the beneficial owner through a stockbroker or bank or
     shares purchased through the SEMCO Energy, Inc. 401(k) plan ("401(k)
     Plan").

Q:   WHAT IS THE DIFFERENCE BETWEEN HOLDING SHARES AS A SHAREHOLDER OF RECORD
     AND AS A BENEFICIAL OWNER?
A:   Many shareholders of the Company hold their shares through a stockbroker,
     bank or other nominee rather than directly in their own name. As summarized
     below, there are some differences between shares held of record and those
     beneficially owned.

     Shareholders of Record. If your shares are registered directly in your
     ----------------------
          name with our transfer agent, Wells Fargo Bank Minnesota, NA, you are
          considered the shareholder of record with regard to those shares. As
          the shareholder of record, you have the right to grant your proxy
          directly to us to vote your shares on your behalf at the meeting or
          the right to vote in person at the meeting. A proxy card is enclosed
          for you to use to grant your proxy to us.

     Beneficial Owner. If your shares are held in a stock brokerage account or
     ----------------
          by a bank or other nominee, you are considered the beneficial owner of
          shares held in street name, and these materials are being forwarded to
          you by your broker or nominee, which is considered the shareholder of
          record with respect to those shares. As the beneficial owner, you have
          the right to direct your broker or nominee how to vote and are also
          invited to attend the annual meeting. However, since you are not the
          shareholder of record, you may not vote these shares in person at the
          meeting unless you obtain a signed proxy from the shareholder of
          record giving you the right to vote the shares. Your broker or nominee
          has enclosed or provided a voting instruction card for you to use to
          direct your broker or nominee how to vote these shares.

Q:   HOW CAN I VOTE MY SHARES IN PERSON AT THE ANNUAL MEETING?
A:   Shares held directly in your name as the shareholder of record may be voted
     in person at the annual meeting. If you choose to do so, please bring the
     enclosed proxy card or proof of identification. Even if you plan to attend
     the annual meeting, the Company recommends that you vote your shares in
     advance as described below so that your vote will be counted if you later
     decide not to attend the meeting.

     Shares held in street name (see beneficial owner explanation above) may be
     voted in person by you only if you obtain a signed proxy from the record
     holder giving you the right to vote the shares.

Q:   HOW CAN I VOTE MY SHARES WITHOUT ATTENDING THE ANNUAL MEETING?
A:   Whether you hold shares directly as the shareholder of record or
     beneficially in street name, you may direct your vote without attending the
     annual meeting by Internet, telephone or completing and mailing your proxy
     card or voting instruction card in the enclosed pre-paid envelope. Please
     refer to the enclosed materials for details.

Q:   WHAT DOES IT MEAN IF I RECEIVE MORE THAN ONE PROXY OR VOTING INSTRUCTION
     CARD?
A:   It means your shares are registered differently or are in more than one
     account. Please provide voting instructions for all proxy and voting
     instruction cards you receive.

Q:   CAN I CHANGE MY VOTE?
A:   You may change your proxy instructions at any time prior to the vote at the
     annual meeting. You may accomplish this by entering a new vote by Internet
     or telephone or by granting a new proxy card or new voting instruction card
     bearing a later date (which automatically revokes the earlier proxy
     instructions) or by attending the annual meeting and voting in person.
     Attendance at the annual meeting will not cause your previously granted
     proxy to be revoked unless you specifically so request.

Q:   HOW ARE VOTES COUNTED?
A:   In the election of directors, you may vote "FOR" all of the nominees or
     your vote may be "WITHHELD" with respect to one or more of the nominees. If
     you sign your proxy card or broker voting instruction card with no further
     instructions, your shares will be voted in accordance with the
     recommendations of the Board.


                                       5





Q:   WHAT IS THE VOTING REQUIREMENT TO ELECT DIRECTORS?
A:   In the election for directors, the four persons receiving the highest
     number of "FOR" votes will be elected.

Q:   WHAT IS THE QUORUM REQUIREMENT FOR THE ANNUAL MEETING?
A:   The Company had approximately 18,828,000 shares of Common Stock (Common
     Shares) outstanding on the record date. A majority of the Common Shares
     constitutes a quorum.

BENEFICIAL OWNERSHIP
- --------------------

     To the Company's knowledge, the following is the only person who owns
beneficially more than 5% of the Common Shares as of the record date.

amendment to update their holdings.

(1)  Each person has sole power to vote and sell Common Shares shown, except
     Shares held jointly with spouses or directly by spouses, minor children,

     Shares in this Account may not be voted by the individual directors, but
     may be voted by the full Board.

(4)  The directors, nominees and current executive officers as a group
     beneficially own 1.20% of outstanding Common Shares. Including options
     exercisable within 60 days of February 18, 2003, the same group
     beneficially owns 2.28% of outstanding Common Shares. Each individual
     holds less than one percent of outstanding Common Shares. In 1999, the
     Board established new stock ownership guidelines for directors. Within
     five years of adoption of the guidelines or within five years of joining
     the Company, whichever is later, each non-employee director is expected to
     own Common Shares equal in value to five times the director's annual
     retainer.


                         ITEM 1--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. Shareholders may vote
their shares cumulatively at the meeting by indicating on the ballot how the
votes are to be distributed among the directors.

     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 persons, each of whom
is currently a director of the Company:


                                John T. Ferris
                               Michael O. Frazer
                              Frederick S. Moore

     The Board does not expect that any nominee will become unavailable to
serve as a director. 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 to the extent not inconsistent with shareholder direction. As
shown on the proxy, shareholders may direct that their shares be voted for less
than all four of the above-named nominees.

(1)  No options were exercised in 2002 by the named executive officers.

(2)  Option values are based on the difference between the exercise price and
     the closing price for the Company's stock of $6.10 per share on December
     31, 2002. Because each exercise price was greater than $6.10 for each
     option, the option values are zero.


EMPLOYMENT AND RELATED AGREEMENTS

     Mr. Jackson's employment agreement, which is for a term of five years
ending May 31, 2006, provides for an annual base salary of at least $360,000, a
one-time cash signing bonus of $60,000, a guaranteed cash bonus for 2001 of
$100,000, and thereafter, eligibility for an annual cash incentive bonus with
an annual target of 60% of his annual base salary payable upon attainment of
specific targets. In addition, the agreement provides for options to purchase
200,000 Common Shares at the market value on June 1, 2001. Thereafter, Mr.
Jackson will have an annual target of 50,000 options, based on performance. The
agreement also provides for a severance payment if the Company terminates his
employment other than for "cause", "death" or "disability" or if Mr. Jackson
resigns due to a required relocation of personal residence or a demotion in
position, authority, etc. The severance amount will equal two times Mr.
Jackson's annual salary. The Company will also continue insurance and similar
benefit plans for 24 months, subject to certain limitations.

     In addition, Mr. Jackson's Employment Agreement provides for an early
retirement "Bridge", designed to compensate Mr. Jackson for the difference
between (a) his projected KCPL pension at the KCPL pension plan early
retirement date and (b) the KCPL pension projected at the KCPL pension plan
early retirement date based on employment termination at May 31, 2001. The
Agreement accordingly provides that the Company shall pay Mr. Jackson an
incremental monthly pension of $5,416.37 per month beginning the first day of
the month coincident with or next following the later of his 55th birthday or
the last day of his employment with the Company.

     Mr. Jackson's change-of-control employment agreement has parallel
provisions to his employment agreement except that the severance amount equals
2.99 times his annual base salary and average bonus. Ms. Bradley, Mr. Madigan
and Mr. Schneider have change-of-control employment agreements parallel to Mr.
Jackson's, but without the retirement "Bridge" discussed above. The agreements
also provide for the grossed-up payment of any Federal excise taxes due from
the executive officers as a result of any payments received under the
agreements and provide up to three years of continued participation in the
Company's benefit programs. Each of such agreements has an indefinite term. Mr.
Warsinske has a change in control agreement that provides for a severance
amount equal to one year's salary, computed as his highest annual W-2
compensation from the Company during the last three years. Mr. Warsinske's
change in control agreement expires April 1, 2003 unless extended by the Board
of Directors.

Mr. Cifolelli left the Company before his benefits vested in the Pension Plan.

     At age 65, a Pension Plan participant can receive an annual pension equal
to 1.4% of his average five-year adjusted compensation multiplied by his years
of service. Thus, after 25 years, the Pension Plan provides a benefit based on
35% of such average compensation. 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, 2003, years of service earned were as follows: Mr.
Jackson--1.6 years, Mr. Madigan--2.4 years, Mr. Schneider--4.6 years, Mr.
Warsinske--24.7 years, and Ms. Bradley--4.8 years. At the time of his
retirement, Mr. Kosht had 15.4 years of service earned.


SUPPLEMENTAL PENSION PLAN FOR EXECUTIVES

     Each named executive officer above, except for Mr. Cifolelli, is a party
to the Supplemental Executive Retirement Plan ("SERP"), which provides for
additional retirement benefits for fifteen years after five years of service.
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.

     The SERP also provides pension benefits which could not be provided by an
Employee Pension Plan because of the limit on compensation ($200,000 in 2002).
In addition, the SERP 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 vesting of benefits (under other circumstances) before age
55 and before 5 years of service.

     In an effort to reduce the Company's liability under the SERP, the Company
has offered "buy-outs", or is in the process of making offers, to certain
participants in the SERP. Messrs. Madigan and Warsinske have accepted buy-outs
in lieu of continued participation in the SERP.


TOTAL PENSION BENEFITS

     The following table sets forth the estimated annual benefits payable at
normal retirement age (65) under the Pension Plan and SERP combined. Benefits
under the SERP are paid for 15 years. Benefits under the Employee Pension Plan
last for the life of the executive.

* Final Base Salary means the base salary for the executive at time of
  retirement. The SERP benefit is based on final base salary. The smaller
  benefit from an Employee Pension Plan is based on five-year average
  compensation (salary plus bonus). This table assumes that an executive's
  final base salary will approximate his five-year average compensation.

DIRECTOR COMPENSATION

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

     For their services on the Board, non-employee directors are paid a
retainer of $1,000 per month. Board Committee Chairmen receive an additional
retainer of $400 per month. The Lead Director receives an additional retainer
of $1,700 per month.


  Meeting Fees
  ------------

     Each non-employee director received $1,000 for each Board meeting attended
and $800 for each Board Committee meeting attended by Committee members. Board
Committee Chairmen each received an additional meeting fee of $200 per
Committee meeting chaired. Directors are reimbursed for expenses incurred in
attending Board and Committee meetings.

     In addition to the Board and Committee meetings, the Board held 4 strategy
planning sessions during 2002 for which they were compensated as regular Board
meetings.


  Other Compensation
  ------------------

     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 may not participate in the medical program. Directors who do not
participate in the Company's medical program receive a grant of $3,850 worth of
Common Shares each year.

     In 2001, the Board adopted a Stock Grant Plan for Non-Employee Directors,
pursuant to which each non-employee director receives a grant of 500 Common
Shares each year while a member of the Board.

     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 the Deferred Compensation and Common Stock Purchase Plan for
Non-Employee Directors, directors' cash compensation may be deferred for each
upcoming year. If deferred, compensation accrues interest at the prime rate or
is invested in newly issued Common Shares with dividends reinvested through the
dividend reinvestment plan. Four directors deferred some or all cash
compensation for 2002, which was used to purchase Common Shares. Five directors
have chosen to purchase Common Shares by deferring some or all cash
compensation for 2003.


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

     Each non-employee director also receives an annual grant on each March 1
of non-qualified stock options exercisable at fair market value on date of
grant to acquire 1,000 Common Shares 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.

            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 five non-employee directors. The Committee intends to provide
salary and other non-incentive compensation for an executive comparable to that
paid to executives with similar experience, responsibilities and authority in
other comparably sized companies in the same line of business. Incentive plans
provide each executive with an opportunity for additional 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.

     Pursuant to the terms of Mr. Jackson's employment agreement, he has an
annual target bonus of up to 60% of base salary, based on performance.

     Bonuses under the Company's Short-Term Incentive Plan 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.

     Incentive awards in lieu of bonuses under the Short-Term Incentive Plan
may be granted by the Board 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.

     Pursuant to the terms of Mr. Jackson's employment, he has an annual target
of 50,000 stock options, based on performance. Such options are subject to the
provisions of the Company's Long-Term Incentive Plan (LTIP) and Stock Option
Plan of 2000 (SOP) and successor plans in effect at the date of grant.

     The LTIP was approved by the shareholders at the Annual Meeting held April
15, 1997. Awards to Mr. Jackson 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 under the LTIP range from 5,250 to 10,500 shares.

     The SOP allows stock options to be granted in excess of the LTIP maximum
number to the extent deemed appropriate by the Committee. However, no single
person may be issued SOP stock options relating to more than 1% of outstanding
stock at the time of grant and no more than 5% of outstanding stock may be
issued pursuant to exercises of options granted under any non-shareholder
approved option plan.

     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.

annual meeting, SEC rules will permit management to vote proxies in its
discretion if the Company: (1) receives notice of the proposal before the close
of business on January 29, 2004, and advises shareholders in the 2004 proxy
statement about the nature of the matter and how management intends to vote on
such matter; or (2) does not receive notice of the proposal prior to the close
of business on January 29, 2004.

     Management knows of no matters (other than those listed on page 1) which
are to be brought before the meeting. However, if any other matters are
presented for action, it is the intention of the persons named in the enclosed
proxy to vote in accordance with their judgment.

     It is important that proxies be returned promptly to avoid unnecessary
expenses. Therefore, all Common Shareholders (even those planning to attend the
meeting) are urged, regardless of the number of Common Shares owned, to sign,
date and return the enclosed proxy in the business-reply envelope, also
enclosed, or submit proxy voting instructions by telephone in accordance with
the instructions on the enclosed proxy card. Shareholders attending in person
may withdraw their proxies and vote in person.

                                    OF THE
                                AUDIT COMMITTEE


                                    PURPOSE

The primary purpose of the Audit Committee of SEMCO Energy, Inc. (the
"Company") is to assist the Board of Directors in fulfilling its responsibility
to oversee (i) management's conduct of the Company's financial reporting

public or other users thereof, (ii) the Company's systems of internal
accounting and financial controls, (iii) the annual independent audit of the
Company's financial statements and (iv) the Company's legal compliance and
ethics programs as established by management and the Board.

In discharging its oversight role, the Committee is empowered to investigate
any matter brought to its attention, with full access to all books, records,
facilities and personnel of the Company. The Board and the Committee are in
place to represent the Company's shareholders; accordingly, the Company's

                  of the Company's independent auditor, (c) former employees of

                  through (c) above; and

           (iv)   who are financially literate or who become financially

                                        A-1





    II.   COMMITTEE CHAIRPERSON

          Annually, the Committee will appoint one of the Committee's members as
          Chairperson. No Chairperson shall serve more than three consecutive
          years. The Chairperson presides over the meetings of the Committee and
          reports to the Board.


   III.   ADMINISTRATIVE SECRETARY

          of Directors may appoint a Director to fill such vacancy for the

     V.   RESPONSIBILITIES

          It is the responsibility of the Audit Committee to understand and
          assess the financial reporting and internal controls of the Company.
          The Committee's job is one of oversight. It recognizes that the
          Company's management is responsible for preparing the Company's
          financial statements and that the independent auditors are responsible
          for auditing those statements. Additionally, the Committee recognizes
          that financial management, as well as independent auditors, have more
          time, knowledge and more detailed information regarding the Company

          internal auditors. If the internal audit function is performed by
          employees of the Company, the Committee shall have the authority to
          evaluate the performance of the function as a whole and determine
          whether or not the function should be performed by employees or
          outsourced.

          auditor must be pre-approved by the Audit Committee.

          from independent legal, accounting or other advisors.

                     IMPORTANT NOTICE REGARDING DELIVERY OF
                              SHAREOWNER DOCUMENTS




March 10, 2003

Dear Shareowner,

The Securities and Exchange Commission has adopted a rule that allows us to send
a single copy of our annual reports, proxy statements, prospectuses and other
disclosure documents to two or more shareowners sharing the same address if they
consent to do so, subject to certain conditions. We believe this "Householding"
rule will provide greater convenience for our shareowners, as well as cost
savings for us by reducing the number of duplicate documents that are sent to
your home. PLEASE NOTE THAT IF YOU DO NOT RESPOND, YOU WILL BE DEEMED TO HAVE
CONSENTED, AND HOUSEHOLDING WILL START 60 DAYS AFTER THE MAILING OF THIS NOTICE.

The Householding election appears on the enclosed proxy card. If you wish to
participate in the Householding program, please mark "FOR" on the enclosed proxy
card and return it in the enclosed postage-paid envelope provided. Your
affirmative or implied consent will be perpetual unless you withhold it or
revoke it.

If you wish to continue to receive separate annual reports, proxy statements,
prospectuses and other disclosure documents for each account in your household,
you must withhold your consent to our Householding program by marking the
"AGAINST" box on the enclosed proxy card and returning it in the enclosed return
envelope. EVEN IF YOU VOTE BY TELEPHONE OR INTERNET, THE ENCLOSED PROXY CARD
MUST STILL BE RETURNED AND MARKED APPROPRIATELY IF YOU WISH TO WITHHOLD YOUR
CONSENT TO HOUSEHOLDING.

You may revoke your consent at any time by contacting ADP, either by calling
toll-free (800) 542-1061, or by writing to ADP, Householding Department, 51
Mercedes Way, Edgewood, New York 11717. If you revoke your consent, you will be
removed from the Householding program within 30 days of receipt of your
revocation and each shareowner at your address will receive individual copies of
our disclosure documents.

We strongly encourage your participation in the Householding program, and
believe that it will benefit both you and SEMCO. Not only will it reduce the
volume of duplicate information that you receive in your household, but it will
also reduce our printing and mailing costs.

Thank you.
