      THIS STOCK OPTION AGREEMENT is effective as of the Grant Date stated

      WHEREAS, the options described in this Agreement have been granted
pursuant to, and are governed by, the Plan;

      NOW, THEREFORE, SEMCO Energy, Inc. and the Optionee hereby agree as
follows:

1. OPTION GRANT. Subject to the terms and conditions of this Agreement, the
Company hereby grants an option to the Optionee to purchase from the Company, at

Option.

2. VESTING.

      (a) REGULAR VESTING. Except as stated in Sections 2(b) and 2(c) of this
Agreement, the Optionee shall become vested in a percentage of the Total Shares
Under Option in accordance with the following schedule:

--------------------------------            -------------------

First anniversary of Grant Date                     33%
Second anniversary of Grant Date                    33%

</TABLE>

                                       1
<PAGE>

The number of shares granted to the Optionee under this Agreement which become
vested on a Vesting Date in accordance with the above schedule will be
determined by multiplying the Total Shares Under Option by the percentage
specified in the above schedule, and then rounding the resulting number up to
the nearest whole number, provided that the aggregate number of the Optionee's
vested shares under this Agreement shall not exceed the Total Shares Under
Option. Notwithstanding anything in this Agreement to the contrary, no Vesting
Date will occur following Optionee's termination of employment with the Company.

      (b) ACCELERATED VESTING. Notwithstanding the vesting schedule specified in
Section 2(a) of this Agreement, the Total Shares Under Option shall become 100%
vested upon the earliest to occur of the following Vesting Dates:

            (i)   the Optionee's Retirement Date;

            (ii)  the Optionee's Disability Retirement Date;

            (iii) the date of the Optionee's death prior to his termination of
                  employment from the Company; or

            (iv)  the date of a Change of Control;

If more than one of the accelerated vesting rules specified in this Section 2(b)
can apply to the Optionee, the Optionee will be deemed to have elected the
available accelerated vesting rule which provides the longest exercise period.

      (c) TERMINATION FOR CAUSE. Notwithstanding anything in this Agreement to
the contrary, if the Company terminates the Optionee's employment for Cause
prior to a Change of Control, this Agreement shall be terminated and all options
granted to the Optionee under this Agreement shall be forfeited, regardless of
whether a Vesting Date has occurred on or before such termination date, unless
and to the extent that the Committee determines that such forfeiture would
violate applicable law.

3. EXERCISE OF OPTIONS.

      (a) GENERAL. Except as otherwise specified by the Committee in accordance
with Sections 3(c) and 3(d), the Optionee (or his Representative, as the case
may be) may exercise the

                                       2
<PAGE>

options granted under the Agreement, in whole or in part, at any time on or
after the Vesting Date for such options and prior to their Expiration Date, by
complying with the procedures described in this Section 3. The Optionee shall
forfeit all rights to any option under this Agreement, whether or not then
vested, which is not exercised prior to its Expiration Date.

      (b) EXERCISE PROCEDURE. The Optionee or his Representative (if applicable)
may exercise all or a portion of his vested options under this Agreement by
delivering notice to the Company. The notice shall specify the number of shares
of Stock that the Optionee desires to purchase by exercise of his vested
options, and shall include payment for the Exercise Amount of such shares in one
of the following ways:

            (i)   The Optionee may tender payment of the Exercise Amount on the
                  date of exercise in the form of cash, certified check, bank
                  draft, or postal or express money order made payable to the
                  order of the Company and denominated in U.S. dollars; or

            (ii)  The Optionee may tender payment of the Exercise Amount on the
                  date of exercise in the form of shares of Stock having a Fair
                  Market Value on the date of exercise equal to the Exercise
                  Amount (if such shares were acquired upon exercise of an
                  option, they must have been held by the Optionee for at least
                  six months at the time of tender); or

            (iii) The Optionee may tender payment of the Exercise Amount on the
                  date of exercise in a combination of (A) shares of Stock
                  (subject to the holding period described in paragraph (ii)
                  above); and (B) cash, certified check, bank draft, or postal
                  or express money order made payable to the order of the
                  Company and denominated in U.S. dollars, equal to the
                  difference between the Exercise Amount and the Fair Market
                  Value of the tendered shares of Stock on the date of exercise;
                  or

            (iv)  The Optionee may initiate a cashless exercise in accordance
                  with procedures promulgated by the Committee, if any.

                                       3

Within 30 days after the date of such exercise, the Company shall make available
to the Optionee a certificate registered in the Optionee's name or a book entry
in a depository institution for the Optionee's account, representing the
aggregate number of shares of Stock purchased by the Optionee as a result of
such exercise.

      (c) EXERCISE OF OPTIONS DURING LEAVE OF ABSENCE. Notwithstanding any
provision of this Agreement to the contrary, if the Optionee is on a leave of
absence or is absent on military or government service at any time on or after
the Grant Date and prior to the Expiration Date, the Optionee may not exercise
any part of the Total Shares Under Option prior to the date the Optionee returns
to active employment with the Company, and vesting of any options under this
Agreement which would normally vest on a date during the absence shall be
postponed until the Optionee returns to active work at the end of the absence
(in which case, the date of return to active employment shall be a Vesting
Date). The provisions of this subsection (c) shall not affect any of Optionee's
rights in the event of his death, Disability, Retirement or in the event of a
Change of Control occurring during such an absence.

      (d) DEFERRAL OF EXERCISE OR DELIVERY OF SHARES. Notwithstanding any
provision in this Agreement to the contrary, if any law or regulation of any
governmental authority having jurisdiction in the matter requires the Company,
Committee, Optionee, or Representative to take any action or refrain from action
in connection with the exercise of any option under this Agreement or the
delivery of shares of Stock to the Optionee, or to delay such exercise or
delivery, then the exercise or delivery of such shares shall be deferred until
such action has been taken or such restriction on action has been removed.

4. RULES GOVERNING THE EXPIRATION DATE. The Expiration Date for options granted
to the Optionee under this Agreement shall be subject to the following rules:

 Performance Period             January 1,        through

</TABLE>

      THIS PERFORMANCE SHARE UNIT AGREEMENT is effective as of the Grant Date
stated above, by and between SEMCO Energy, Inc. and the Grantee.

      WHEREAS, the Performance Share Units described in this Agreement have been
granted pursuant to, and are governed by, the Plan;

      NOW, THEREFORE, the Company and the Grantee hereby agree as follows:

1. PERFORMANCE SHARE UNIT GRANT. Subject to the terms and conditions of this
Agreement, the Company hereby grants to Grantee a Target Grant of Performance
Share Units as specified above.

2. AWARD OF PERFORMANCE SHARE UNITS.

      (a) The Grantee will receive an award of a percentage of his Target Grant
of Performance Share Units as of the last day of the Performance Period if he
remains actively employed with the Company on such date and if the threshold
level of performance is met or exceeded with respect to at least one of the
performance goals established by the Committee for such Performance Period.

<PAGE>

      (b) Schedule A to this Agreement sets forth Grantee's performance goals,
the portion of the Target Grant that will be available for an award with respect
to each performance goal (the "Performance Target") and the percentage of that
Performance Target that will be awarded based upon the actual performance level
achieved with respect to such performance goal during the Performance Period.
The total Performance Share Units awarded pursuant to this Agreement shall equal
the sum of the Performance Share Units awarded with respect to each performance
goal.

3. AWARDS ON CERTAIN EVENTS. Notwithstanding the requirement in Section 2 of
this Agreement that a Grantee be actively employed on the last day of the
Performance Period, Performance Share Units shall be awarded at the end of the
Performance Period pursuant to Section 2 to any Grantee who terminates
employment during the Performance Period:

            (i)   on the Grantee's Retirement Date;

            (ii)  on the Grantee's Disability Retirement Date;

            (iii) on the date of the Grantee's death prior to his termination of
                  employment from the Corporation; or

            (iv)  as a result of a Change of Control.

The number of Performance Share Units awarded pursuant to this Section 3 shall
equal the product of the Performance Share Units that would otherwise be awarded
had the Grantee remained employed until the last day of the Performance Period
multiplied by (1) the number of days the Grantee was employed during the
Performance Period over (2) the number of days in the Performance Period.

4. DELIVERY OF SHARES. Upon certification by the Committee of the achieved
performance under the established performance goals for the Performance Period,
the Performance Share Units awarded pursuant to Section 2 shall be paid to the
Grantee in shares of Stock. Payment of such Shares shall in no event be made
later than the date which is 2 1/2 months after the end of the taxable year in
which the Performance Period ends. Certificates representing such shares of
Stock shall be delivered to the Grantee as soon as practicable after such
payment.

                                       2

5. OWNERSHIP RIGHTS. Upon certification by the Committee in accordance with
Section 4 above, the Grantee shall exercise all ownership rights (including,
without limitation, the right to vote and the right to receive dividends) with
respect to such shares, provided that voting and dividend rights with respect to
the shares will be exercisable only if the record date for determining
shareholders entitled to vote, or to receive dividends, falls on or after the
date of such certification.

6. DEFERRAL OF EXERCISE OR DELIVERY OF SHARES. Notwithstanding any provision in
this Agreement to the contrary, if any law or regulation of any governmental
authority having jurisdiction in the matter requires the Company, the Committee
or the Grantee to take any action or refrain from action in connection with the
award of or delivery of Performance Share Units or Stock under this Agreement,
or to delay such award or delivery, then the award or delivery of such shares
shall be deferred until such action has been taken or such restriction on action
has been removed.

granted to the Grantee shall be nontransferable and shall not be sold,
hypothecated or otherwise assigned or conveyed by the Grantee to any other
