D. It is the desire of the Board of Directors of the Company, pursuant to its authority, to fix the rights, preferences, restrictions and other matters relating to the Undesignated Stock and the number of shares of Undesignated Stock. E. Pursuant to authority given by Article 6 of the Company's Articles of Incorporation, the Company's Board of Directors has adopted the following resolutions as of the 4th day of March, 1999; RESOLVED, that, pursuant to Article 6 of the Articles of Incorporation of WAM!NET Inc.

The number of shares constituting the 1999 Class A Preferred Stock shall be One Hundred Fifteen Thousand Two Hundred and Six (115,206). Each share of 1999 Class A Preferred Stock shall have a par value of Ten Dollars ($10.00) per share. The number of shares of 1999 Class A Preferred Stock may be increased or decreased by resolution of the Board of Directors; provided, that, no decrease shall reduce the number of shares of 1999 Class A Preferred Stock to a number less than the number of shares then outstanding, plus the number of shares of 1999 Class A Preferred Stock, if any, reserved for issuance upon the exercise of outstanding options, rights or warrants or upon the conversion of any outstanding securities issued by the Company convertible into 1999 Class A Preferred Stock. Section 2. Dividends and Distributions. --------------------------- (A) The holders of shares of 1999 Class A Preferred Stock, in preference to the holders of Common Stock of the Company, shall be entitled to receive, when, as and if declared by the Board of Directors of the Company (the "Directors"), a dividend (the "Quarterly Dividend") in the amount of Seventeen and One-half Cents ($.175) per share payable out of the net earnings of the Company constituting funds legally available for the purpose. The Quarterly Dividend shall begin to accrue on January 1, 1999, and shall be payable in cash on the first day of March, June, September and December in each year (each such date being referred to herein as a "Quarterly Dividend Payment Date"), commencing on the first Quarterly Dividend Payment Date after the first issuance of a share or fraction of a share of 1999 Class A Preferred Stock. If the net earnings in any year are not sufficient to pay the Quarterly Dividend, either in whole or in part, then any unpaid portion of such dividend will become a charge against the net earnings of the Company, and will be paid in full out of the net earnings of the Company in subsequent years before any dividends are paid on the Common Stock of the Company in those years. No dividends will be paid or set apart for payment on the Common Stock, no distribution will be made on the Common Stock, and no shares of Common Stock will be redeemed, retired or otherwise acquired for valuable consideration unless all theretofore unpaid Quarterly Dividends have been declared, and the Company has paid those dividends or has set aside a sum sufficient to pay them. (B) Dividends shall begin to accrue and accumulate on outstanding shares of 1999 Class A Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issue of such shares, in which case dividends on such shares shall begin to accrue from the date of issue of such shares, or (i) from such Quarterly Dividend Date if additional consideration, prorated for the number of elapsed days since such Quarterly Dividend Date, is paid upon issuance, (ii) unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of shares of 1999 Class A Preferred Stock entitled to receive Quarterly Dividends and before such Quarterly Dividend Payment Date, in either of which events such Quarterly Dividends shall begin to accrue and accumulate from such Quarterly Dividend Payment Date. Accrued but unpaid Quarterly Dividends shall not bear interest. Dividends paid on the shares of 1999 Class A Preferred Stock in an amount less than the total amount of Quarterly Dividends then accrued and payable shall be allocated pro rata on a share-by-share basis among all such shares of 1999 Class A Preferred Stock then outstanding. The Directors may fix a record date for the determination of holders of shares of 1999 Class A Preferred Stock entitled to receive payment of a dividend or distribution declared thereon, which record date shall be no more than sixty (60) days prior to the date fixed for the payment thereof. Section 3. Voting Rights.

The term of office of any person elected as a director by the holders of 1999 Class A Preferred Stock shall terminate on December 31, 2000. The vacancies created thereby may be filled by resolution of the remaining Directors who shall have been elected by a vote of the holders of the Common Stock of the Company. If the office of a director elected by the holders of 1999 Class A Preferred Stock is vacant prior to December 31, 2000, due to resignation, removal or death, the vacancy shall be filled by the majority vote of the directors then in office, even if less than a quorum, upon the recommendation of the remaining director or directors who were elected by the holders of the 1999 Class A Preferred Stock. If the office of a director who was elected by the holders of Common Stock is vacant prior to December 31, 2000, due to resignation, removal or death, the vacancy shall be filled by the majority vote of the directors then in office, even if less than a quorum, upon the recommendation of the remaining director or directors who were elected by the holders of the Common Stock. If the vacancy is not so filled within forty (40) days after the creation of the vacancy, a special meeting of the holders of Preferred Stock and/or Common Stock shall be called and the vacancy or vacancies shall be filled at that meeting.
