         7. Conversion.

                  (a) Conversion of Note. At any time, Holder shall have the
         right, at Holder's option, to convert the principal and accrued
         interest on this Note, in whole or in part, into common stock, par
         value $0.001, of Mid-Power Service Corporation ("Conversion Stock"), at
         a price of $1.50 per share, subject to adjustment as provided below
         ("Note Conversion Price"). Conversion under this section shall occur
         only upon surrender of this Note for conversion at the principal
         offices of Mid-Power Service Corporation, accompanied by a written
         notice of election to convert, provided, however, that pursuant to the
         limitations set forth in that certain promissory note in the aggregate
         principal amount of $10,000,000 dated as of June 13, 2002, made and
         delivered by Makers, as makers, to Edward Mike Davis ("Davis"), as
         payee (the "Davis Note"), as part of the merger consideration under
         that certain "Acquisition Agreement and Plan of Merger" dated as of
         June 14, 2002, by and between Makers, Red Star, Inc., a Nevada
         corporation, and for the limited purposes set forth therein, Davis, a
         copy of which has been delivered to Payee and to which this Note is
         subject, Holder shall not have any right to convert any principal of or
         interest accrued under the Note if, upon such conversion:

                  (i)      at any time before the Davis Note is paid in full,
                           Holder would have the right to receive any more than
                           3,666,667 shares of Conversion Stock hereunder;

                  (ii)     at any time after the Davis Note is paid in full and
                           before June 13, 2003, the issuance of such Conversion
                           Stock would cause the ownership of Davis to become
                           less than fifty-one percent (51%) of the ownership,
                           beneficial or legal, of Mid-Power Service
                           Corporation; or

                  (ii)     at any time after June 13, 2003, and before the close
                           of business on June 13, 2007, the issuance of such
                           Conversion Stock would cause the ownership of Davis
                           to become less than thirty-six percent (36%) of the
                           ownership, beneficial or legal, of Mid-Power Service
                           Corporation; save and except, in each case, such
                           conversion has been consented to in writing by Davis,
                           in his sole and absolute discretion.

                  (b) Conversion in the Event of Prepayment or Payment of Note.
         At such time that Makers have funds immediately available and elect to
         pay the entire principal balance and accrued interest (whether as a
         prepayment or payment at or after maturity of this Note), Holder shall
         have the option to convert the Note into Conversion Stock at the Note
         Conversion Price on or before 15 days from the receipt of notice of
         Makers' election to pay off the Note. Holder shall have no obligation
         to accept any payment less than the entire principal balance, plus
         accrued interest.

                  (c) Certain Transactions. Makers shall give written notice to
         Holder of any "Change of Control Transaction" at least 20 business days
         prior to the date on which such Change of Control Transaction shall
         take place. Prior to the closing of such Change of Control Transaction,
         Makers shall, at Holder's election, either repay all unpaid principal
         and interest under this Note or convert this Note into Conversion Stock
         at the Note Conversion Price, subject to the limitations set forth
         herein.

                  (d) Issuance of Conversion Stock. As soon as practicable after
         conversion of this Note, Mid-Power Service Corporation, at its expense,
         will cause to be issued in the name of and delivered to Holder of this
         Note, a certificate or certificates for the number of shares of
         Conversion Stock to which Holder shall be entitled upon such conversion
         (bearing such legends as may be required by applicable state and
         federal securities laws in the opinion of legal counsel of Mid-Power
         Service Corporation), together with any other securities and property
         to which Holder is entitled upon such conversion under the terms of
         this Note. Such conversion shall be deemed to have been made under this
         section 6 and immediately prior to the close of business on the date
         that the Note shall have been surrendered for conversion, accompanied
         by written notice of election to convert. No fractional shares will be
         issued upon conversion of this Note. If, upon any conversion of this
         Note, a fraction of a share would otherwise result, then, in lieu of
         such fractional share, Mid-Power Service Corporation will pay the cash
         value of that fractional share, calculated on the basis of the
         applicable Note Conversion Price.

                  (e) Adjustment of Number of Shares. The number and character
         of shares of Conversion Stock issuable upon conversion of this Note (or
         any shares of stock or other securities or property at the time
         receivable or issuable upon conversion of this Note) are subject to
         adjustment upon the occurrence of any of the following events:

                           (i)      Adjustment for Stock Splits, Stock

                                    shall fix a record date for the
                                    determination of holders of securities
                                    affected by any stock split, stock dividend,
                                    reclassification, recapitalization or other
                                    similar event that will, in the future,
                                    affect the number of outstanding shares of
                                    Mid-Power Service Corporation's capital
                                    stock, then, and in each such case, Holder,

                                    after Mid-Power Service Corporation shall
                                    fix the record date for such event, shall
                                    receive, in addition to the shares of

                                    the securities of Mid-Power Service
                                    Corporation to which Holder would have been
                                    entitled if Holder had converted this Note
                                    immediately prior to such record date (all
                                    subject to further adjustment as provided in

                                    In each such case, the terms of the Note
                                    shall be applicable to the shares of stock
                                    or other securities or property receivable

                                    need not be changed because of any
                                    adjustment in the number of shares of
                                    Conversion Stock issuable upon its
                                    conversion.

                           (vii)    Reservation of Stock. Mid-Power Service
                                    Corporation has taken all necessary
                                    corporate action and obtained all necessary
                                    government consents and approvals to
                                    authorize the issuance of this Note and,
                                    prior to the conversion hereof, the shares
                                    of Conversion Stock issuable upon conversion
                                    of this Note. If at any time the number of
                                    authorized but unissued common stock or
                                    other securities shall not be sufficient to
                                    effect the conversion of this Note, then
                                    Mid-Power Service Corporation will take such
                                    corporate action as may, in the opinion of
                                    its legal counsel, be necessary to increase
                                    its authorized but unissued common stock or
                                    other securities as shall be sufficient for
                                    such purpose.

                  (f) Fully Paid Shares. All shares of Conversion Stock issued
         upon the conversion of this Note shall be validly issued, fully paid,
         and nonassessable.

                  (g) No Rights or Liabilities as Stockholder. This Note does
         not by itself entitle Holder to any voting rights or other rights as a
         stockholder of Mid-Power Service Corporation. In the absence of
         conversion of this Note, no provisions of this Note, and no enumeration
         herein of the rights or privileges of Holder, shall cause Holder to be
         a stockholder of Mid-Power Service Corporation for any purpose.

                  (h) Corporate Action; No Impairment. Makers will not, by
         amendment of their articles of incorporation or bylaws, or through
         reorganization, consolidation, merger, dissolution, issuance or sale of
         securities, repurchase of securities, sale of assets or any other
         action, avoid or seek to avoid the observance or performance of any of
         the terms of this Note, but will at all times in good faith assist in
         the carrying out of all such terms and in the taking of all such action
         as may be necessary or appropriate, or as reasonably requested by
         Holder, in order to protect the rights of Holder under this Note
         against wrongful impairment.
