PLAN OF DISTRIBUTION

         The shares being offered by the selling stockholders were issued by us in our acquisition of Pacific Broadband Communications, Inc. pursuant to an Agreement and Plan of Reorganization dated November 11, 2001. The shares of common stock were issued pursuant to an exemption from the registration provisions of the Securities Act. The selling stockholders represented to us that they were acquiring the shares for investment and with no present intention of distributing the shares.

         We will not receive any proceeds from the sale of the shares. Each of the selling stockholders may sell its shares directly or through broker-dealers or underwriters who may act solely as agents or who may acquire shares as principals. The distribution of the shares may be effected in one or more transactions that may take place through the Nasdaq National Market, including block trades or ordinary broker’s transactions, or through privately negotiated transactions, or through a combination of any such methods of sale, at market prices prevailing at the time of sale, at prices related to such prevailing market prices or negotiated prices. Usual and customary or specifically negotiated brokerage fees or commissions may be paid by the selling stockholders in connection with such sales.

         The aggregate proceeds to the selling stockholders from the sale of the shares will be the purchase price of the common stock sold less the aggregate agents’ commissions if any, and other expenses of issuance and distribution not borne by us. The selling stockholders and any dealers or agents that participate in the distribution of the shares may be deemed to be “underwriters” within the meaning of the Securities Act, and any profit on the sale of such shares by them and any commissions received by any such dealers or agents might be deemed to be underwriting discounts and commissions under the Securities Act.

         The selling stockholders may effect transactions by selling shares directly or through broker-dealers acting either as principal or as agent, and such broker-dealers may receive compensation in the form of usual and customary or specifically negotiated underwriting discounts, concessions, or commissions from the selling stockholders.

         To the extent required, the specific shares of common stock to be sold, the names of the selling stockholders, purchase price, public offering price, the names of any such agent, dealer or underwriter, and any applicable commission or discount with respect to a particular offering will be set forth in an accompanying prospectus supplement.
