                  right to have the breach described in writing by Jawerth and
                  the same twenty (20) business day cure period.

                  or for Disability, he shall be entitled to a severance payment
                  equal to two years his then current base annual salary, to be
                  paid in a lump sum at the time of termination. All options
                  that Jawerth has shall immediately vest. He shall also be
                  entitled to receive for one year following termination the
                  health benefits he is then currently receiving from the
                  Company at no greater cost to him than the cost he paid for
                  such benefits immediately prior to his termination.

         (B)      In the event Jawerth terminates his employment for Good
                  Reason, he shall receive severance pay and benefits as if such
                  termination had been by the Company without Cause.

         (C)      In the event Jawerth terminates his employment without Good
                  Reason, he shall be entitled to receive an amount equal to two
                  (2) weeks of his then current salary for each year of service
                  under this Agreement. He shall also be entitled to a
                  continuation of his

                                       10
<PAGE>   11

                  health benefits for three (3) months at no greater cost to him
                  than the cost he paid for such benefits immediately prior to
                  his termination. In addition, if Jawerth terminates his
                  employment without Good Reason or he is terminated for cause
                  within one year of the Closing Date under the Asset Purchase
                  Agreement Jawerth shall return to the Company all options
                  granted under this Agreement.

         (D)      If the Company terminates Jawerth's employment for Cause, he
                  shall be entitled to receive two (2) weeks of his then current
                  salary as severance pay.

         (E)      If this Agreement is terminated due to Jawerth's death, the
                  termination shall be treated as a termination by Jawerth for
                  Good Reason, and any monies and other benefits due, so far as
                  such benefits can be monetized, shall be paid to Jawerth's
                  estate.

7.       HSNS PROPERTY.

         (A)      All intellectual property developed by Jawerth in connection
                  with his employment by the Company shall be the exclusive
                  property of HSNS. During the term of this Agreement and
                  thereafter, Jawerth shall cooperate with the Company to obtain
                  or confirm rights in the intellectual property developed by
                  Jawerth for HSNS, at the Company's expense. Such rights shall
                  include, but not be limited to, filing and prosecuting
                  applications for obtaining or registering patents, trademarks
                  and copyrights.

         (B)      All intellectual property developed by Jawerth entirely on his
                  own time without using any of the Company's equipment,
                  supplies, facilities, Confidential Information, or other
                  assets, and not related to the Business of the Company, shall
                  not be the property of the Company.

                                       11
<PAGE>   12

         (C)      HSNS hereby grants to Bjorn Jawerth, personally, a
                  non-exclusive, non-transferable, world-wide license, without
                  right to sublicense, to make and use New Technology, as such
                  term is defined in the HSNS Inventions Awards Plan, that is
                  developed during the twelve months following Closing under the
                  Asset Purchase Agreement. Any rights of Jawerth under this
                  license are subject to his fiduciary obligations as a director
                  and/or officer of the Company, and to his obligations under
                  Section 8 of this Agreement. Jawerth acknowledges that the
                  Company would not grant such license but for the obligations
                  of Jawerth set forth in Section 8. This license shall
                  terminate on the later of the date twelve months from the
                  Closing or such later date as may be set by the Board,
                  excluding Jawerth (either, the "License Termination Date"). If
                  HSNS ceases to be a Going Concern prior to the License
                  Termination Date, the license shall be perpetual and shall
                  include the rights to sell and offer to sell products and
                  services using the licensed New Technology, and the right to
                  sublicense.

8.       NON-COMPETITION.

         (A)      Jawerth agrees that, for the period of eighteen (18) months
                  immediately following termination of this Agreement for any
                  reason, he will not, without the prior written consent of
                  HSNS, for his own account or jointly with another, directly or
                  indirectly, for or on behalf of any person or entity, as
                  principal, agent or otherwise:

                  (i)      participate in the control or management of or assist
                           a business that develops, markets, licenses out or
                           sells digital media compression products or services

                                       12
<PAGE>   13

                           within the Territory (the "Business"), or assist such
                           a business in the development of digital media
                           compression products or services, or accept
                           employment as a consultant, director, officer or
                           manager by a business engaged in the Business, except
                           HSNS; or

                  (ii)     solicit or induce, or in any manner attempt to
                           solicit or induce, any person employed or engaged by
                           HSNS in any capacity (including, without limitation,
                           as an employee, distributor, independent contractor
                           or agent), to leave such employment or engagement,
                           whether or not such employment or engagement is
                           pursuant to a contract or is at will.

         (B)      Although the parties have, in good faith, used their best
                  efforts to make the provisions of part (a) above reasonable in
                  the scope of activities, geographic area and in duration, and
                  it is not anticipated, nor is it intended, by any of the
                  parties hereto that a Court of competent jurisdiction would
                  find it necessary to reform the provisions hereof to make it
                  reasonable in respect to the scope of activities, geographic
                  area and in duration, or otherwise, the parties understand and
                  agree that if a court of competent jurisdiction determines it
                  necessary to reform the scope of part (a) above in order to
                  make it reasonable in respect to the scope of activities,
                  geographic area or duration, or otherwise, damages, if any,
                  for a breach hereof, as so reformed, would be deemed to accrue
                  to HSNS as of and from the date of such a breach only insofar
                  as the damages for such breach relate to an action which
                  occurred within the scope of activities, geographic area and
                  duration as so reformed.

                                       13

         (C)      For purposes of the foregoing, the "Territory" shall mean the
                  United States of America, Canada, Mexico, the countries of the
                  European Union, East Asia, and India. "Digital media
                  compression products or services" shall include, but not be
                  limited to, products and services involving digital media
                  compression, where media can be audio, video, still images, or
                  animation files.

         (D)      Jawerth acknowledges that the business of the Company in rich
                  media products and services based on digital media compression
                  is international in scope, that eighteen (18) months of
                  restriction is appropriate given the importance of Jawerth's
                  position with the Company, and that Jawerth has received
                  substantial and adequate consideration for his covenants in
                  part (a) above.

9.       CONFIDENTIAL INFORMATION.

         (A)      During the term of this Agreement and for eighteen (18) months
                  following its termination, unless he has the Company's express
                  prior approval with respect to specific information, Jawerth
                  will keep confidential all Confidential Information he
                  receives from the Company, or which he generates during the
                  course of his employment, including technologies owned by the
                  Company. Confidential Information is defined as information
                  not publicly available or which Jawerth did not obtain from
                  non-Company sources that were obligated to keep such
                  information confidential, and information received from third
                  parties that the Company is obligated to keep confidential.
                  Jawerth may disclose Confidential Information, however, if
                  such

                                       14
<PAGE>   15

                  information becomes public through no act or omission of
                  Jawerth, or if Jawerth is ordered to disclose such information
                  by a court of competent jurisdiction.

         (B)      Jawerth agrees that Confidential Information is the sole and
                  exclusive property of the Company or the third parties that
                  provided the Confidential Information to the Company. Should
                  Jawerth leave the Company, he will return to the Company, upon
                  request, all Confidential Information in his possession.

10.      [RESERVED]

11.      WAIVER OF BREACH. A waiver by either party of a breach of any provision
         of this Agreement does not constitute a waiver of any other provision
         of this Agreement; nor does it constitute a continuing waiver of the
         same provision waived.

12.      ASSIGNMENT. Because of the professional services involved, the
         obligations or benefits of Jawerth cannot be assigned without the
         express prior written permission of HSNS, which shall not be
         unreasonably withheld. This Agreement cannot be assigned by HSNS
         without the express prior written approval of Jawerth, which may not be
         unreasonably withheld. This Agreement shall be binding on all
         successors and permitted assigns of HSNS.

13.      INDEMNIFICATION AND INSURANCE. Jawerth shall be entitled to the full
         corporate indemnity and defense protections otherwise provided by the
         Company to its senior officers, through bylaw

                                       15
<PAGE>   16

         provisions, corporate policy, applicable law, or otherwise. The
         indemnification shall also extend to HSNS liabilities before closing
         for actions in which Jawerth had no involvement. HSNS shall carry
         standard directors and officers insurance.

14.      GOVERNING LAW. This Agreement shall be governed by the laws of North
         Carolina. The venue for any dispute relating to or arising under this
         Agreement shall be Raleigh, North Carolina, unless the parties agree
         otherwise in advance. Before any litigation is instituted, the parties
         to any such dispute shall first pursue mediation, and if such mediation
         does not resolve the dispute, then binding Arbitration, under the rules
         of the American Arbitration Association. The parties hereby consent to
         jurisdiction in North Carolina for the purpose of any litigation
         relating to this Agreement and agree that any litigation by or
         involving them relating to this Agreement shall be conducted in the
         courts of Wake County, North Carolina or the federal courts of the
         United States for the Eastern District of North Carolina.

15.      PERFORMANCE. Jawerth agrees that he will perform his duties and conduct
         himself in accordance with applicable laws.

16.      THIRD PARTY BENEFICIARIES. Other than permitted successors and assigns,

         third parties, including without limitation the members of any

                             VOTING TRUST AGREEMENT

         THIS VOTING TRUST AGREEMENT (the "Agreement") is made and entered into
as of the 16th day of February, 2001, among Dr. Bjorn Jawerth ("Stockholder"),
High Speed Net Solutions, Inc., a Florida corporation, together with any of its
majority-owned subsidiaries (the "Company"), and Stuart Diamond (the "Trustee").

                              BACKGROUND STATEMENT

         The Stockholder is the owner and holder of the number of shares of the
Company (the "Shares") set forth opposite his name and signature below. The
Asset Purchase Agreement, as amended, dated as of October 30, 2000 (the
"Purchase Agreement") requires the Stockholder to execute and deliver this
Agreement as a condition to the issuance of Share Purchase Price under the
Purchase Agreement. The Company, the Stockholder and other stockholders desire
to provide for orderly governance of the Company.

         The term "Shares" in this Agreement shall mean shares of the Company
beneficially owned shares or owned and currently held shares or any shares
acquired by Stockholder in the future, except that any shares removed from the
coverage of this Agreement through the provisions of Section 4(b) or 4(c) shall
not be included. The term "beneficial" or "beneficially" or "beneficial owner"
shall have the meaning given in Exhibit A to this Agreement.

                             STATEMENT OF AGREEMENT

         1. NOW, THEREFORE, in consideration of the foregoing recitals and the
mutual covenants and agreements herein contained and the transactions
contemplated hereby and thereby, the parties hereby covenant and agree as
follows:

         2. Transfer. Stockholder hereby assigns to the Trustee the Shares, to
be held by the Trustee under the terms and conditions of this Agreement.
Stockholder hereby authorizes and directs the Company to transfer the Shares to
the Trustee on the books of the Company. The Company will issue to the Trustee,
as trustee, a new certificate representing the Shares and the parties hereby
agree to execute and deliver such documents as the Company may reasonably
request to effectuate such transaction. The parties hereto acknowledge that the
voting trust hereby created shall apply during its term to all securities of the
Company (or any successor company) received by Stockholder (or any transferee of
the Shares), whether by dividend, stock split, merger, share exchange,
liquidation or otherwise. The parties further agree that any cash or other
property (other than securities

<PAGE>   2

of the Company or successor company) received in any such exchange or otherwise
for the Shares shall be distributed by the Trustee to Stockholder as
appropriate.

         3. Voting Trust Certificates. The Trustee will issue to Stockholder a
Voting Trust Certificate evidencing his beneficial ownership of the Shares held
by the Trustee.

         4. Transfer of Voting Trust Certificates.

            (a) Except as provided in Section 4(b) and 4(c) below, Stockholder
         may not transfer his Voting Trust Certificates, his interest in the
         voting trust hereby created, or the Shares, without the prior written
         consent of the Trustee. Consent to transfer of Voting Trust
         Certificates shall not be withheld if the proposed transferee executes
         and delivers to the Trustee agreements in form and substance reasonably
         acceptable to the Trustee, whereby the proposed transferee agrees to be
         bound by this Agreement. To the extent permitted hereunder, any such
         transfer of Voting Trust Certificates and any subsequent transfers
         shall be made only on the books of the Trustee by the record holder
         thereof or by his legal representative, who shall furnish the Trustee
         with proper evidence of authority to transfer, or by his attorney
         thereunto authorized by power of attorney duly executed and filed with
         the Trustee, and on surrender for cancellation of the Voting Trust
         Certificate.

            (b) Each month commencing on the first month anniversary of this
         Agreement, one twelfth (1/12) of the Shares subject to this Agreement
         shall be released from the provisions of this Agreement until all
         Shares are no longer subject to this Agreement. Upon release of all of
         the Shares from this Agreement, this Agreement shall automatically
         terminate. All Shares released shall continue to be subject to the
         limitations of the Purchase Agreement regarding public sale.

            (c) Nothing in this Agreement shall prevent Stockholder from making
         a sale of Shares to a bona fide third party transferee, other than a
         relative, agent or affiliate of Stockholder, such that Stockholder will
         cease to be the beneficial owner of the Shares after the sale. Shares
         sold pursuant to this Section 4(c) shall be released from this
         Agreement.

         5. Term. This Agreement will terminate on the first of (a) mutual
agreement of the Company and Stockholder, or (b) the termination of this
Agreement pursuant to Section 4(b) above.

         6. Rights and Duties of Trustee. The Trustee will have full power to
vote, consent, and otherwise exercise all the voting rights in respect of the
Shares held by it hereunder as the Trustee, and the Trustee shall vote the
Shares as directed by a majority of the Board of Directors of the Company. The
Trustee will not be liable for any act or failure

                                       2

<PAGE>   3

to act arising hereunder. Trustee hereby agrees to vote the Shares as determined
by Trustee without consultation with or direction from Stockholder.

         7. Dividends. The holders of the Voting Trust Certificates will be
entitled to receive any dividends (other than dividends of securities of the
Company or any successor company) paid on the shares represented by their Voting
Trust Certificates. The Trustee shall direct the Company to make payment or
delivery of any such dividends directly to the holders of the Voting Trust
Certificates.

         8. Securities Dividends. If the Company pays a dividend by delivery to
the Trustee of securities of the Company or any successor company, the Trustee
shall retain and hold any such securities as Trustee pursuant to the terms of
this Agreement and will deliver to the holders of the Voting Trust Certificates
additional Voting Trust Certificates representing such securities.

         9. Successor Trustee. The Trustee may not be removed for any reason.
The Trustee may resign at any time by written notice to the registered holders
of Voting Trust Certificates. The Trustee may give any person or entity a proxy
to vote the Shares, which proxy shall terminate not later than termination of
this Agreement. Any such proxy must be in writing signed by the Trustee. Upon
the resignation, death or disability of the Trustee, the Company may select a
successor Trustee by action of its Board of Directors. The Trustee and his
successors as Trustee may act as Trustees hereunder whether or not they are also
stockholders of the Company, officers or directors of the Company, or holders of
Voting Trust Certificates hereunder. Except as set forth in this Section 9,
Stockholder may not assign his right under this Agreement to any other party
without the prior written consent of all parties hereto. The Company may assign
its rights under this Agreement to any majority owned subsidiary.

         10. Notices. Any and all notices, requests, demands or other
communications provided for hereunder shall be given in writing and shall be
deemed to have been given (a) when received, if delivered in person, (b) one
business day after deposit with an overnight delivery service, addressed as set
forth on the signature page hereof, or (c) three (3) business days following the

                                    EXHIBIT A

         The term "beneficially," when used in connection with the ownership of
securities, means (a) any interest in a security which entitles you to any of
the rights or benefits of ownership even though you may not be the owner of
record or (b) securities owned by you directly or indirectly, including those
held by you for your own benefit (regardless of how registered) and securities
held by others for your benefit (regardless of how registered), such as by
custodians, brokers, nominees, pledgees, etc., and including securities held by
an estate or trust in which you have an interest as legatee or beneficiary,
securities owned by a partnership of which you are a member (whether a general
or limited partner), securities held by a personal holding company of which you
are a stockholder, etc., and securities held in the name of your spouse or any
other member of your immediate family.

         A "beneficial owner" of a security includes any person who, directly or
indirectly, through any contract, arrangement, understanding, relationship or
otherwise has or shares:

                  (1)   voting power which includes the power to vote, or to
                  direct the voting of, such security; and/or

                  (2)   investment power which includes the power to dispose, or
                  to direct the disposition, of such security.

         In addition, you will be deemed to be the beneficial owner of any
security for which you have the right to acquire the voting or investment power
within 60 days, including any right to acquire such security (a) through the
exercise of any option, warrant or right, (b) through the conversion of a
security, (c) pursuant to the power to revoke a trust, discretionary account or
similar arrangement, or (d) pursuant to the automatic termination of a trust,
discretionary account or other similar arrangement.

         Any person who, directly or indirectly, creates or uses a trust, proxy,
power of attorney, pooling arrangement or any other contract, arrangement, or
device with the purpose or effect of divesting such person of beneficial
ownership of a security or preventing the vesting of such beneficial ownership
as part of a plan or scheme to evade the reporting requirements of Sections
13(d) or 13(g) of the Securities Exchange Act of 1934, as amended, shall be
deemed for purposes of such sections to be the beneficial owner of such
security.
