happening of any contingency).

         h.       Summus Stock: 250,000 shares of common stock of Summus
Technologies, Inc. a Florida corporation;

         2.       EXCHANGE OF SHARES.

         a.       Dunavant agrees to sell and the Company agrees to purchase the
Summus Stock, now owned by him, the consideration for which purchase and sale
shall be as set forth in Section 2(b), and which purchase and sale shall be
contingent on the full completion of the Company's responsibilities under this
Agreement.

         b.       In exchange for Dunavant's Summus Stock, the Company agrees as
follows:

                  i.       Simultaneously with the execution of this Agreement

         respect to the Registrable Shares pursuant to Section 3 hereof has not
         become effective for any reason on or before 120 days from the date of
         the execution of this Agreement, then, 135 days from the date of
         execution of this Agreement, duly-authorized certificates for 25,000
         shares of Registrable Securities, bearing a legend referring to the
         Registration Rights conferred hereby; and each 30 days thereafter at
         which point a Registration Statement filed with the SEC with respect to
         the Registrable Shares pursuant to Section 3 hereof has not become
         effective for any reason, an additional 25,000 shares of Registrable
         Securities.

         a.       As expeditiously as possible, but in no event later than 60
days after the date hereof, the Company shall file a registration statement with
the SEC on Form S-1, or such other form as the Commission may prescribe for the
sale of the Registrable Securities, so as to permit the sale or other
disposition of the Registrable Shares promptly upon the effectiveness of such
registration. The registration statement shall cover that number of Registrable
Shares to which, at the time of the effectiveness of the registration statement,
Dunavant shall be entitled pursuant to this Agreement. The registration process
with respect to Registrable Securities pursuant to this Section 3 shall be
referred to herein as "Demand Registration".

         b.       The Company shall thereafter diligently, conscientiously and
actively pursue the processing of such registration statement through the
Commission's Division of Corporation Finance, and shall use its best efforts to
have the registration declared effective by the Company as soon as practicable.

         c.       The Company shall maintain the effectiveness of such
registration statement and, if necessary, amend the registration statement and
supplement the prospectus included therein for a period of no less than two (2)
years from the effective date of such registration statement, or such sooner
time as counsel for the Company shall render his written unqualified legal
opinion, in a form reasonably satisfactory to Dunavant and the Company's
Transfer Agent, that Dunavant is legally permitted to sell all such Registrable
Securities held by Dunavant without volume restrictions under Rule 144
promulgated under the Securities Act.

         4.       EXPENSES OF REGISTRATION. The Company shall be responsible for
and shall pay all expenses (including, without limitation, registration fees,
filing fees, qualification fees, Blue Sky fees and expenses, Company legal fees
and expenses, printing expenses and costs of special

                                       4
<PAGE>   5

audits or "cold comfort" letters, underwriting discounts and commissions
incident to the Demand Registration.

         5.       INDEMNIFICATION. In connection with any registration,
qualification, notification, or exemption of Registrable Securities hereunder,
the Company and each of its undersigned officers and directors shall indemnify
Dunavant against all losses, claims, damages and liabilities caused by any
untrue, or alleged untrue, statement of a material fact contained in any
registration statement or prospectus or notification or offering circular (and
as amended or supplemented if the Company shall have furnished any amendments or
supplements thereto) or any preliminary prospectus or caused by any omission, or
alleged omission, to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, except insofar as
such losses, claims, damages or liabilities are caused by any untrue statement
or alleged untrue statement or omission based upon information furnished in
writing to the Company by Dunavant, and the Company, the underwriter for the
Company and each person who controls the Company within the meaning of Section
15 of the Securities Act shall be indemnified by Dunavant for all such losses,
claims, damages and liabilities caused by any untrue, or alleged untrue,
statement or any omission or alleged omission, based upon information furnished
in writing to the Company by Dunavant for any such use.

         6.       REGISTRATION PROCEDURES AND COVENANTS. The Company shall
periodically keep Dunavant advised, in writing, as to the initiation progress
and effective date of the Demand Registration, and, at the expense of the
Company, the Company shall:

         a.       unless the Registrable Securities are exempt by law from the
blue sky laws of any jurisdiction, use its best efforts to register or qualify
such Registrable Securities under such other securities or blue sky laws of such
jurisdictions as Dunavant reasonably requests and do any and

                                       5
<PAGE>   6

all other acts and things which may be reasonably necessary or advisable to
enable such Holder to consummate the disposition in such jurisdictions of the
Registrable Securities owned by such Holder (provided that the Company will not
be required to: (i) qualify generally to do business in any jurisdiction where
it would not otherwise be required to qualify but for this Section hereof; (ii)
subject itself to taxation in any such jurisdiction; or (iii) consent to general
service of process in any such jurisdiction);

         b.       cause to be filed any and all notifications to any
governmental authority under any federal or state securities law to be sent and
any and all listings with any securities exchange or Nasdaq to be obtained, as
may be reasonably necessary or advisable to enable Dunavant to consummate the
disposition of their Registrable Securities pursuant to the registration;

         c.       notify Dunavant at any time when a prospectus relating thereto
is required to be delivered under the Securities Act of the occurrence of any
event as a result of which the prospectus included in such registration
statement contained an untrue statement, and

         d.       notify Dunavant of a material fact or omission to state any
fact necessary to make the statements therein not misleading, and promptly
prepare a supplement or amendment to such prospectus so that, as thereafter
delivered to the purchasers of such Registrable Securities, such prospectus
shall not contain an untrue statement of a material fact or omit to state any
fact necessary to make the statements therein not misleading;

         e.       provide a transfer agent and registrar for all such
Registrable Securities not later than the effective date of such registration
statement.

         7.       RULE 144 REPORTING AND SALES. With a view to making available
to Dunavant the benefits of certain regulations of the SEC which may permit the
sale of the Registrable Securities

                                       6
<PAGE>   7

to the public without registration, the Company agrees that, so long as Dunavant
owns any Registrable Securities, the Company shall:

         a.       make and keep available "public information," as that term is
defined in SEC Rule 144 or its successor, and as may be applicable to the
Company at the time;

         b.       timely file with the SEC all reports and other documents
required to be filed under the Securities Act and the Exchange Act, if during
such time, the Company shall be required to do so;

         c.       comply with all rules and regulations of the SEC applicable in
connection with the use of Rule 144; and

         d.       take such other actions and furnish Dunavant with such other
information as he may reasonably request in order to avail him of the benefits
of any rule or regulation of the SEC allowing him to sell any Registrable
Securities without registration. The Company also agrees to furnish to Dunavant
promptly upon request a written statement by the Company as to its compliance
for a period of at least ninety (90) days prior to the date of the certificate
with the reporting requirements of the Securities Act and the Exchange Act and a
copy of the most recent annual or quarterly report of the Company.

         e.       Nothing in this Section 7 or elsewhere in this Agreement shall
be construed to limit the Company's obligations with respect to the registration
of the Registrable Securities. Dunavant's rights under Rule 144 shall be
supplementary to and independent of his rights with respect to the registration
of the Registrable Securities, and he may choose, in his sole option and
discretion, to avail himself of the benefits under Rule 144.

         8.       SUCCESSORS, ASSIGNS AND TRANSFEREES. This Agreement shall be
binding upon and shall inure to the benefit of the parties hereto and their
respective heirs, personal representatives,

                                       7
<PAGE>   8

successors and assigns. In addition, and whether or not any express assignment
shall have been made, the provisions of this Registration Rights Agreement which
are for the benefit of Dunavant shall also be for the benefit of and enforceable
by any subsequent Holder of any Registrable Securities, subject to the
provisions and obligations hereof.

         9.       ENTIRE AGREEMENT AND MODIFICATIONS. This Agreement constitutes
the entire understanding between the parties and supersedes all other
agreements, whether written or oral, with respect to the transactions
contemplated by this Agreement. The Agreement may not be amended or modified by
either party unless such amendment or modification is memorialized in a writing
signed by each of the parties hereto. Any such amendment or modification of this
Agreement shall be binding upon and inure to the benefit of all Holders of
Registrable Securities.

         10.      WAIVER. Any waiver by either party of any breach of any term
or condition in this Agreement shall not operate as a waiver of any other breach
of such term or condition or of any other term or condition, nor shall any
failure to enforce any provision hereof operate as a waiver of such provision or
of any other provision hereof or constitute or be deemed a waiver or release of
any other rights, in law or in equity.

         11.      GOVERNING LAW. All issues concerning this Agreement will be
governed by and construed in accordance with the laws of the State of Florida,
without giving effect to any choice of law or conflict of law provision or rule
(whether of the State of Florida or any other jurisdiction) that would cause the
application of the law of any other jurisdiction. The parties hereto agree that
any action to enforce this Agreement may be properly brought in any court within
the State of Florida.

         12.      SEVERABILITY. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision

                                       8
<PAGE>   9

of this Agreement is held to be invalid, illegal or unenforceable in any respect
under any applicable law or rule in any jurisdiction, such invalidity,
illegality or unenforceability shall not affect any other provision or the
effectiveness or validity of any provision in any other jurisdiction, and this
Agreement will be reformed, construed and enforced in such jurisdiction as if
such invalid, illegal or unenforceable provision had never been contained
herein.

         13.      ADDITIONAL STEPS AND PROCEDURES. From time to time after the
execution of this Agreement, each of the parties hereto hereby agrees to use all
reasonable efforts to take, or cause to be taken, all action and to do, or cause
to be done, all things necessary, proper and advisable under applicable laws,
rules and regulations to consummate and make effective the transactions
contemplated by this Agreement, including using its best efforts to obtain all
necessary waivers, consents and approvals. In case at any time after the
execution of this Agreement further action is necessary or desirable to carry
out the purposes of this Agreement, the proper officers and directors of each of
the parties shall take all such necessary action.

         14.      NOTICES. All notices and other communications which are
required or may be given under this Agreement shall be in writing and shall be

Registrable Shares, unencumbered with any restrictions, covenants, loans,
mortgages, security interests or

                                       2
<PAGE>   3

other devices or conditions; provided, however, that Dunavant acknowledges that
these 150,000 Registrable Shares will be issued to Dunavant as Restricted
Securities under the federal securities laws.

         B.       HSNS shall also deliver additional Registrable Shares,
unencumbered with any restrictions, covenants, loans, mortgages, security
interests or other devices or conditions (except that Dunavant acknowledges that
these shares will be issued to Dunavant as Restricted Securities under the
federal securities laws), commencing with a first delivery of stock on the
Execution Date, and continuing each month thereafter on the monthly anniversary
of the Execution Date, in such amount of shares each month as described in
paragraphs II.B(i) and II.B(ii) below. HSNS' obligation to deliver shares under
this paragraph II.B shall terminate upon HSNS fulfilling its obligation under
paragraph II.C to cause an effective registration statement to be available for
the Registrable Shares of HSNS stock that enables Dunavant to sell the
Registrable Shares.

                  (i)      During the period commencing on the Execution Date
and ending on the day before the first monthly anniversary following January 1,
2001, the number of additional Registrable Shares delivered to Dunavant per
month under this paragraph II.B shall be 25,000.

                  (ii)     During the period commencing on the first monthly
anniversary following January 1, 2001, and continuing thereafter, the number of
additional Registrable Shares delivered to Dunavant per month under this
paragraph II.B shall be 50,000 shares. The number of additional Registrable
Shares delivered to Dunavant per month under this paragraph II.B shall remain at
the amount of 50,000 shares until HSNS has delivered an effective registration
statement for the Registrable Shares.

         C.       On or before July 1, 2000, HSNS shall file a registration
statement with the SEC for all Registrable Shares owned by, or due and owing to,
Dunavant, and shall thereafter use all reasonable efforts and dispatch,
including but not limited to responding to SEC comments and filing amendments to
the registration statement, to enable the SEC to declare the registration
statement effective at the earliest possible date. All costs and expenses of the
registration process, including but not limited to professional fees for
preparing the registration statement and assisting HSNS during the registration
process, shall be borne by HSNS.

         D.       If on the effective date of the registration statement, the
ten-day moving average closing price for HSNS stock is less than $23 per share,
then HSNS shall increase the number of

                                       3
<PAGE>   4

Registrable Shares covered by the registration statement to make up the
difference between (a) the product obtained by multiplying $23 by the sum of
400,000 plus any additional shares delivered pursuant to paragraph II.B., and
(b) the product obtained by multiplying the ten-day moving average closing price
for HSNS stock as of the effective date of the registration statement by the sum
of 450,000 plus any additional shares delivered pursuant to paragraph II.B
(hereinafter, the "Difference"). The number of Registrable Shares to be included
to make up the Difference shall be computed by dividing the Difference by the
ten-day moving average closing price for HSNS stock as of the effective date of
the registration statement. HSNS shall deliver this number of additional shares
to Dunavant on the effective date of the registration statement.

         E.       It shall be deemed a material breach of this Agreement by HSNS
if for any reason the registration statement has not been declared effective by
the SEC by January 1, 2001. In that event, Dunavant shall have the right but not
the obligation immediately to commence arbitration proceedings, as hereunder
described, against HSNS, provided that no delay by Dunavant in commencing such
proceedings shall be deemed a waiver of any rights that Dunavant has under this
Agreement.

         F.       To the extent permitted by law, Dunavant shall be free, but
not obligated, to sell any Registrable Shares of HSNS common stock under SEC
Rule 144. Any such shares sold by Dunavant under SEC Rule 144 shall be
subtracted from the calculation of Registrable Shares as prescribed above.

         G.       HSNS shall pay Dunavant Twelve Thousand Seven Hundred Fifty
Dollars ($12,750) on the Effective Date of this Agreement.

         H.       HSNS shall pay Dunavant Twelve Thousand Seven Hundred Fifty
Dollars ($12,750) each month on or before the monthly anniversary of the
Effective Date during the period commencing on the first monthly anniversary
after the Execution Date and ending on the last day of the month in which the
registration statement for the Registrable Shares is declared effective by the
SEC.

         I.       The parties agree that the provisions of paragraphs II.B, II.
G, and II.H are not a penalty and that they represent a reasonable attempt to
remedy the economic harm accruing to Dunavant from delays in resolving the
controversies surrounding HSNS' compliance with the August 13, 1999 Agreement.

         J.       HSNS shall require Alan Kleinmaier to sign a non-compete
agreement whereby he is unable to compete with HSNS through, and including, the
effective date of the registration statement for the Registrable Shares.

                                       4
<PAGE>   5

         K.       Dunavant shall not allow any HSNS stock owned by him to be
shorted on or before the effective date of a registration statement.

         L.       Dunavant shall have "piggyback" registration rights should the
shares of any entity be registered under the Securities Act by HSNS prior to the
effective date of the registration statement for the Registrable Shares.

III.     SATISFACTION OF JUDGMENT OR DISMISSAL OF THE LITIGATION

         A.       Dunavant shall contemporaneously with the execution of this
Agreement execute either the Satisfaction of Judgment (attached as Exhibit A and
incorporated by this reference) or the Stipulation of Dismissal (attached as
Exhibit B and incorporated by this reference) as necessary.

IV.      RELEASE OF CLAIMS

         A.       Release by Dunavant

                  Dunavant hereby releases HSNS, together with each of its
officers, directors, agents, employees, attorneys, and representatives, for any
and all claims, actions, causes of action, or liabilities of any sort or
character, whether known or unknown, arising from the beginning of time to the
Execution Date of this Agreement which were asserted in the Litigation or could
have been asserted in the Litigation.

         B.       Release by HSNS

                  HSNS, together with its officers, directors, agents,
employees, attorneys, and representatives, hereby releases Dunavant for any and
all claims, actions, causes of action, or liabilities of any sort or character,
whether known or unknown, arising from the beginning of time to the Execution
Date of this Agreement which were asserted in the Litigation or could have been
asserted in the Litigation.

         C.       No Release of Obligations under this Agreement

                  Nothing herein shall constitute a release by any party of any
person of his or its obligations under this Agreement.

confidential by the parties, and shall not be disclosed to any third party

otherwise provided herein. This Agreement may be provided to a party's attorney,
accountant, or financial advisor, subject to such party's agreement to maintain
the confidentiality of the agreement and its terms and conditions. This
Agreement may also be provided to a governmental authority or the public when
there is a legal obligation to provide the document to such authority. Except as
required by law, the parties shall make no comment to any third party, including
but not limited to any press release, about the settlement of the Litigation
other than stating that the claims in the Litigation have been dismissed with
prejudice and that the dispute has been settled to the mutual satisfaction of
all parties.

         B.       Third-Party Requests

                  In the event that the terms or conditions of this Agreement
shall be requested by a third party in a legal proceeding, by subpoena, document
request, or otherwise, the party receiving the request shall provide notice to
the other party pursuant to the notice provisions of this Agreement in
sufficient time to allow the other party the opportunity to intervene and limit
or prevent the disclosure in that legal proceeding. In any case, the producing
party shall make all reasonable efforts to obtain confidential treatment of the
Agreement or its terms and conditions in any legal proceeding.

VI.      ARBITRATION

         A.       Controversies to be Arbitrated

                  Any dispute, controversy, or claim under this Agreement shall
be finally resolved by arbitration in Miami, Florida, in accordance with the
Commercial Arbitration Rules of the American Arbitration Association and
enforced by a single arbitrator who shall be an attorney experienced in
securities law matters and selected by the parties. If the parties are unable to
agree upon an attorney, an attorney experienced in securities law matters shall
be appointed by the American Arbitration Association in accordance with its
rules.

VIII.    ACKNOWLEDGMENTS

         The parties previously entered into a Settlement Agreement, dated May
4, 2000 (the "Original Settlement Agreement"). The parties have agreed to amend
and restate the Original Settlement Agreement because certain provisions of the
Original Settlement Agreement became impossible to perform due to the discovery
of a published SEC interpretation regarding an issue about which HSNS was
required to deliver a legal opinion. Without the legal opinion the original
Settlement Agreement could not be fully performed and the parties have therefore
negotiated new terms and conditions as expressed in this Agreement.

         The parties acknowledge and agree that: (i) no stock or consideration
was issued by HSNS to Dunavant under the Original Settlement Agreement; (ii) any
transfers of possession or ownership of any HSNS shares owned by Michael Cimino
in partial performance of the Original Settlement Agreement are rescinded and
Dunavant shall use his best efforts to unwind, rescind, and reconvey such
transferred shares; and (iii) that this Agreement replaces entirely the Original
Settlement Agreement and the parties shall have no obligations whatsoever
arising from the Original Settlement Agreement.

         Cimino is a party to this Agreement solely for the purposes of this
Section VIII. Cimino agrees, acknowledges and affirms that the Original
Settlement Agreement is rescinded and is null and void. Cimino agrees,
acknowledges and affirms that the letter agreement dated May 2, 2000 between
Cimino and HSNS is rescinded and is null and void. Cimino warrants and
represents that there are no understandings or agreements of any kind or nature
between Cimino and HSNS or between Cimino and Dunavant arising from or relating
to the Litigation or the Original Settlement Agreement.

         This Agreement supersedes in full any and all previous conversations,
understandings, tentative agreements or actual agreements resolving or
attempting to resolve the Litigation.

IX.      MISCELLANEOUS

         A.       Binding Nature of Agreement

                  This Agreement shall be binding on HSNS (as defined above),
Dunavant (as defined above), and Cimino (as defined above) and their respective
successors and assigns.

         B.       Application of Florida Law

                  This Agreement shall be construed in accordance with the laws
of the State of Florida without giving effect to principles of conflict of laws.

         C.       No Admission of Liability

                  This Agreement constitutes a compromise of disputed claims,
and is entered into to avoid the costs and uncertainties of litigation. By
entering into this Agreement, no party hereto admits any liability whatsoever,
and any such liability is expressly denied.

         D.       Severability

                  Whenever possible, each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Agreement is held to be invalid, illegal or
unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or the effectiveness or validity of any provision in any
other jurisdiction, and this Agreement will be reformed, construed and enforced
in such jurisdiction as if such invalid, illegal or unenforceable provision had
never been contained herein.

         E.       Entire Agreement

                  This Agreement and its exhibits hereto contain the entire
agreement of the parties. They are intended to supersede and replace any prior
or contemporaneous agreement of the parties with respect to the subject matter
of this Agreement and its exhibits, which includes, but is not necessarily
limited to, the settlement of the Litigation. No party has relied on any oral
representations whatsoever in entering into this Agreement or its exhibits, and
the only written representations that are or have been relied on are those
expressly made in this Agreement. This Agreement and its exhibits shall be
modified only in a writing executed by all parties thereto which specifically
and expressly refer to this Agreement.

         F.       Neutral Construction

                  This Agreement has been drafted with the cooperation and
participation of all parties and their attorneys. Accordingly, no part of this
Agreement shall be construed in favor of or against any party.

         G.       Additional Steps and Procedures

                  From time to time after the execution of this Agreement, each
of the parties hereto hereby agrees to use all reasonable efforts to take, or
cause to be taken, all action and to do, or cause to be done, all things
necessary, proper and advisable under applicable laws, rules and regulations to
consummate and make effective the transactions contemplated by this Agreement,
including using its best efforts to obtain all necessary waivers, consents and
approvals. In case at any time after the execution of this Agreement further
action is necessary or desirable to carry out the purposes of this Agreement,
the proper officers and directors of each of the parties shall take all such
necessary action.

         H.       Warranty of HSNS

                  HSNS warrants that, prior to the execution of this Agreement
by Dunavant, it has made public disclosure, by a disseminated press release, of
all material information concerning the status and terms of any negotiations and
discussions between HSNS and any other person or representative of any other
person concerning any merger, share exchange, or sale of all or substantially
all of HSNS's assets.

         I.       Execution in Counterparts

                  This Agreement may be executed in multiple counterparts, each
constituting an original document for all purposes for which an original
document may be required.
