                                  AMENDMENT OF

                            EQUITY COMPENSATION PLAN

         THIS AMENDMENT is effective as of the 1st day of May 2000, by High
Speed Net Solutions, Inc., a Florida corporation (the "Company").

                                   WITNESSETH:

         WHEREAS, the Company has previously established and adopted the High
Speed Net Solutions, Inc. Equity Compensation Plan (the "Plan"), effective
January 31, 2000; and

         WHEREAS, pursuant to Section 13.1 of the Plan, the Board of Directors
may amend the Plan.

         NOW, THEREFORE, in consideration of the premises herein contained, the
Company hereby amends the Plan as follows:

         1.       A new Section 3.15 of the Plan is hereby added to read in its
entirety as follows:

         "In connection with any underwritten public offering by the Company of
         its equity securities pursuant to an effective registration statement
         filed under the Securities Act of 1933, including the Company's initial
         public offering, a Participant shall not sell, make any short sale of,
         loan, hypothecate, pledge, grant any option for the purchase of, or
         otherwise dispose or transfer for value or otherwise agree to engage in
         any of the foregoing transactions with respect to, any Stock acquired
         under the Plan without the prior written consent of the Company or its
         underwriters. Such restriction (the "Market Stand-Off") shall be in
         effect for such period of time from and after the effective date of the
         final prospectus for the offering as may be requested by the Company or
         such underwriters. In no event, however, shall such period exceed the
         period for which securities owned by the Chief Executive Officer of the
         Company are subject to the same restrictions. Any new, substituted or
         additional securities that are by reason of any recapitalization or
         reorganization distributed with respect to Stock acquired under the
         Plan shall be immediately subject to the Market Stand-Off, to the same
         extent the Stock acquired under the Plan is at such time covered by
         such provisions. In order to enforce the Market Stand-Off, the Company
         may impose stop-transfer restrictions with respect to the Stock
         acquired under the Plan until the end of the applicable stand-off
         period."

         2.       Appendix A is hereby added to the Plan and the new Appendix A
shall read in its entirety as provided in Exhibit I to this document.

<PAGE>   2

         3.       This Amendment does not supersede the terms and conditions of
the Plan, except to the extent expressly described herein. Terms not otherwise
defined in this Amendment will have the meanings ascribed to such terms in the
Plan.

         IN WITNESS WHEREOF, this Amendment is effective as of the 1st day of
May 2000.

                                   APPENDIX A

                         HIGH SPEED NET SOLUTIONS, INC.
                         1999 EQUITY COMPENSATION PLAN

                  PROVISIONS APPLICABLE TO CALIFORNIA RESIDENTS

Notwithstanding anything to the contrary specified elsewhere in the Plan, the
following provisions shall apply to any stock option granted under the High
Speed Net Solutions, Inc., 2000 Equity Compensation Plan (the "Plan") to a
resident of California:

-        The exercise price for an option granted to a California resident may
         not be less than 85% of the "fair value" (as defined by Rule 260.140.50
         under the California Code) of the Company's common stock at the time
         the option is granted. However, in the case of an option granted to a
         resident of California who owns stock possessing more than 10% of the
         total combined voting power of all classes of stock of the issuing
         corporation or its parent or subsidiary corporations at the time of
         grant, the exercise price shall be 110% of the "fair value."

-        The exercise period of a stock option granted to a California resident
         shall be no longer than 120 months from the date the option is granted.

-        An option granted to a California resident shall not be transferable,
         other than by will or the laws of descent and distribution.

-        An option granted to a California resident shall vest and become
         exercisable at the rate of at least 20% per year over 5 years from the
         date the option is granted, subject to reasonable conditions such as
         continued employment. However, in the case of an option granted to a
         California resident who is an officer, director, or consultant of the
         Company or any of its affiliates, the option may become fully
         exercisable, subject to reasonable conditions such as continued
         employment, at any time or during any period established by the
         Company.

-        Unless employment is terminated for cause as defined by applicable law,
         the terms of the stock option award agreement or a contract of
         employment, and in the event of termination of the optionee's
         employment (to the extent that the optionee is otherwise entitled to
         exercise on the date employment terminates) the right to exercise an
         option granted to a California resident must expire as follows:

-        At least 6 months from the date of termination if termination was
         caused by death or disability; or

                                       3
<PAGE>   4

-        At least 30 days from the date of termination if termination was caused
         not due to death or disability.

-        The plan shall terminate with respect to California residents on
         January 31, 2010.

-        The Plan shall be available to California residents only if the
         shareholders of the Company approve the plan within 12 months before or
         after the date the plan was adopted. Any option exercised by a
         California resident before such shareholder approval is obtained shall
         be rescinded if such shareholder approval is not obtained. Any such
         rescinded shares will not be counted in determining whether approval is
         obtained.

-        Each California resident who elects to participate in the Plan will be
         provided with a copy of the Company's financial statements annually.

-        At no time will the total number of shares of Company stock issuable
         under stock options granted under this Plan, under subscription
         agreements under any stock purchase plan maintained by the Company, and
         the total number of shares provided for under any stock bonus or
         similar plan of the Company exceed a number of shares which is equal to
         30% of the then outstanding shares of the issuer (convertible preferred
         shares are counted on an as if converted basis) as set forth in Rule
         260.140.45 under the California Code.

-        If an Option granted to a California resident provides the Company the
         right to repurchase securities upon the termination of employment, the
         repurchase price will be not less than the fair market value of the
         securities to be repurchased on the date of termination of employment,
         and the right to repurchase must be exercised for cash or cancellation
         of purchase money indebtedness within 90 days of termination of
         employment (or, in the case of securities issued upon exercise of
         options after the date of termination, within 90 days after the date of
         the exercise). The Company's repurchase right terminates when the
         Company's securities become publicly traded. In addition to the
         restrictions set forth above, the securities held by an officer,
         director or consultant of the issuer or an affiliate of the issuer may
         be subject to additional or greater restrictions.
