reasonable in respect to the scope of activities, geographic area and in
duration, or otherwise, the parties understand and agree that if a Forum of
competent jurisdiction determines it necessary to reform the scope of this
PARAGRAPH 4.5 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.

                  (c)      The parties acknowledge that the Acquired Business is
international in scope, and that eighteen (18) months is a reasonable duration
for the provisions of PARAGRAPH


                                       8
<PAGE>   10

4.5 above in order for HSNS to commercialize and exploit the technology acquired
as part of the Acquired Assets.

         4.6      NONDISCLOSURE AGREEMENT. HSNS, Summus and each Stockholder
acknowledge and agree to abide by and be bound by each of the terms and
conditions contained in the nondisclosure agreement previously entered into by
certain of the parties hereto.

         4.7      CURRENT SUMMUS EMPLOYEES. Summus and the Stockholders shall
use their best efforts after the Closing to cause each of the persons employed
by Summus as of the Closing Date and set forth on SCHEDULE 4.7 to accept
employment by HSNS if offered by HSNS.

         4.8      EMPLOYEE OPTIONS. All Summus stock options will be cancelled
at Closing in accordance with the Summus stock option plan. HSNS shall issue
stock options to Summus option holders, to replace stock options in Summus stock
that are cancelled at Closing. The former Summus option holders will be given
options on the number of HSNS shares equal to 18.5629 times the number of Summus
shares covered by the cancelled options, including credit for vested options
that were not exercised prior to cancellation. The share purchase price will be
the lesser of the fair market value of HSNS Common Stock on the date of Closing
or on the date of this Agreement. Time to vesting shall not be longer than the
period provided in the cancelled Summus option agreements, and credit will be
given for time passed under the Summus agreements. Other terms shall be in
accordance with standard HSNS stock option agreements.

         4.9      CONFIDENTIAL INFORMATION. Summus and each Stockholder shall
use its or his best efforts to protect Confidential Information (as defined
below). Summus and each Stockholder will not use (other than for HSNS' benefit)
or disclose any of Summus' Confidential Information. For purposes of this
Agreement, "CONFIDENTIAL INFORMATION" shall mean information, without regard to
form, relating to Summus' customers, operation, finances, and business that
derives economic value, actual or potential, from not being generally known to
other persons, including, but not limited to, technical or nontechnical data,
formulas, patterns, compilations (including compilations of customer
information), programs, devices, methods, techniques, processes, financial data
or lists of actual or potential customers (including identifying information
about customers), whether or not in writing. Confidential Information includes
information disclosed to Summus or the Stockholders by third parties that Summus
is obligated to maintain as confidential. Confidential Information subject to
this Agreement may include information that is not a trade secret under
applicable law, but information not constituting a trade secret only shall be
treated as Confidential Information under this Agreement for a period of two (2)
years after the Closing.

         4.10     BOARD OF DIRECTORS & SENIOR MANAGEMENT.

                  (a)      Prior to the Closing, HSNS and Summus agree that each
party shall maintain its own Board of Directors having a majority of members who
are not "INSIDERS." Until the Closing, a Special Committee of the Summus Board
of Directors will set guidelines for Summus' expenditures and must approve any
proposed deviation from these guidelines before any such expenditure are made.
Immediately following the Closing, the size of the HSNS Board shall be increased
to ten, current members of the Board of Directors of HSNS (the "HSNS BOARD"),
Herman Rush, Richard Seifert, Cristine Wittress, Andrew Fox, and Bjorn Jawerth,
shall remain on the HSNS Board. Kenneth Marks, Stuart Diamond, Chris Gaertner,
Wendi


                                       9
<PAGE>   11

Tush, and a new CEO shall be elected to the HSNS Board. All directors must
stand for re-election after one year at the annual shareholder meeting as per
HSNS' by-laws.

                  (b)      The following provision shall terminate one hundred
twenty (120) days after the Closing: Two Directors from each of HSNS and Summus
(other than Andy Fox and Bjorn Jawerth (hereafter referred to as "INSIDERS")
shall be appointed as a committee to evaluate management changes and additions.
The current management as of the date of this Agreement shall remain in place,
unless a majority of the Members of the HSNS Board of Directors who are not
Insiders decide otherwise. Members of the HSNS Board of Directors who are not
Insiders must approve all proposed significant deviations from HSNS's business
strategy. Both HSNS directors (Rush, Siefert, Wittress, Fox) and Summus
directors (Jawerth, Diamond, Marks) must approve all contracts having a value in
excess of $50,000.

         4.11     FAIRNESS HEARING

                  (a)      As soon as reasonably practicable following the
execution of this Agreement, HSNS and Summus shall prepare, and the Stockholders
shall cause Summus to prepare, the necessary documents and HSNS shall apply to
obtain an order of approval (a "NORTH CAROLINA PERMIT") from the Secretary of
State of the State of North Carolina (after a hearing before such Secretary)
pursuant to Section 78A-30 of the North Carolina Securities Act. Summus and HSNS
will respond to, and the Stockholders will cause Summus to respond to, any
comments from the Secretary of State of North Carolina and use their
commercially reasonable efforts to have the North Carolina Permit granted as
soon as practicable after such filing, if applicable.

                  (b)      In the event the Secretary of State of the State of
North Carolina shall fail to grant a North Carolina Permit in a timely manner,
or the North Carolina Permit is not available prior to the Closing, HSNS in its
sole and absolute discretion may issue the Stock Purchase Price in a private
placement in accordance with applicable federal and state securities laws.

         4.12     RESTRICTIONS ON TRANSFER. All certificates representing HSNS
Common Stock deliverable to Summus and/or the Stockholders pursuant to this
Agreement and in connection with the transactions described herein and any
certificates subsequently issued with respect thereto or in substitution
therefor (including any shares issued or issuable in respect of any such shares
upon any stock split, stock dividend, recapitalization, or similar event) shall
bear any legend required by the Secretary of State of the State of North
Carolina or such as are required pursuant to any federal, state, local or
foreign law governing such securities.

         4.13     EMPLOYEE BENEFITS. Following the Closing, HSNS shall provide
to officers and employees of Summus employee benefits based on the positions
they hold with HSNS after the Closing under employee benefit plans on terms and
conditions which are substantially similar in the aggregate to those provided by
HSNS to their similarly situated officers and employees after the Closing. With
respect to any benefits plans of HSNS in which the officers and employees of
Summus participate after the Closing, HSNS shall use reasonable efforts to: (i)
waive any limitations as to pre-existing conditions, exclusions and waiting
periods with respect to participation and coverage requirements applicable to
such officers and employees under any welfare benefit plan in which such
employees may be eligible to participate after the Closing (provided, however,
that no such waiver shall apply to a pre-existing condition of any such


                                       10
<PAGE>   12

officer or employee who was, as of the Closing, excluded from participation in a
Summus benefit plan by nature of such pre-existing condition), (ii) provide each
such officer and employee with credit for any co-payments and deductibles paid
prior to the Closing during the year in which the Closing occurs in satisfying
any applicable deductible or out-of-pocket requirements under any welfare
benefit plan in which such employees may be eligible to participate after the
Closing, and (iii) other than with respect to vesting credit with respect to
HSNS options granted to such officers and employees, recognize all service of
such officers and employees with Summus for all purposes (including, without
limitation, purposes of eligibility to participate, vesting credit, entitlement
for benefits, and benefit accrual) in any benefit plan in which such employees
may be eligible to participate after the Closing, except to the extent such
treatment would result in duplicative accrual of benefits for the same period of
service.

         4.14     INTERIM FINANCING.

                  (a)      HSNS has previously provided to Summus a loan of
$500,000 (the "PRIOR LOAN") pursuant to a loan agreement dated August, 2000 (the
"LOAN AGREEMENT"). Under the Loan Agreement, Summus is required to provide
security for repayment, in the form of HSNS Common Stock owned by Summus, in
value at least 2.5 times the amount of the debt under the Loan Agreement.

                  (b)      HSNS agrees to provide to Summus, under the terms of
the Loan Agreement, an additional $235,000 on October 30, 2000, and every two
weeks thereafter (the "INTERIM FINANCING") until the earlier of (i) the Closing
Date or (ii) three months after the date of this Agreement. A condition to each
advance of Interim Financing by HSNS is the provision of adequate security to
HSNS, in the form of HSNS Common Stock, so that the total value of security held
by HSNS will be at least 2.5 times the total of the Prior Loan and the amount of
Interim Financing that will have been provided after that advance, plus any
accrued interest.

                  (c)      The sole and exclusive remedy for failure of HSNS to
make any advance of Interim Financing when scheduled shall be termination of
this Agreement. Acceptance by Summus of any advance shall be deemed a waiver of
any right to terminate that had previously arisen under this PARAGRAPH 4.14(C).

                  (d)      On the Closing Date, the Prior Loan and any interest
thereon shall be paid by cancellation of Common Stock held as security therefor,
having Market Value equal to the debt being repaid and the remaining Common
Stock serving as security for the Prior Loan, provided to HSNS prior to October
30, 2000, shall be returned to Summus.

                  (e)      If the Closing occurs, the debt represented by the
Interim Financing shall be cancelled, and Common Stock held as security therefor
shall be returned to Summus.

                  (f)      If the Closing does not occur within sixty (60) days
of the date of this Agreement, due to termination of this Agreement or
otherwise, the Interim Financing shall be paid by cancellation of Common Stock
held as security therefor, having Market Value equal to the debt being repaid.
Any remaining Common Stock held as security shall be returned to Summus.

         4.15     PIGGYBACK REGISTRATION.

                  (a)      Company Registration. If a North Carolina Permit is
not obtained as described above, and the Stock Purchase Price is provided by
private placement of Common Stock, and at any time or from time to time HSNS
shall determine to register any of its securities, either for its own account or
for the account of security holders, other than a registration relating solely
to employee benefit plans, a registration on Form S-4 relating solely to an SEC
Rule 145 transaction, or a demand registration by stockholders who may have
demand rights, HSNS will:

                           (i)      Promptly (but in any event within 10
business days) give to each Stockholder written notice thereof; and

                           (ii)     Include in such registration (and any
related qualification under state securities laws or other compliance), and in
any underwriting involved therein, all the Common Stock included in the Stock
Purchase Price specified in a written request or requests, made within 30 days
after receipt of such written notice from HSNS, by any Stockholder or
Stockholders, except as set forth in part (b) below.

         Such Common Stock shall only be included to the extent that inclusion
will not diminish the number of securities included by HSNS.

                  (b)      Underwriting. If the registration of which HSNS gives
notice is for a registered public offering involving an underwriting, HSNS shall
so advise the Stockholders as a part of the written notice given pursuant to
part (a)(i) above. In such event the right of any Stockholder to registration
pursuant to this PARAGRAPH 4.15 shall be conditioned upon such Stockholder's
participation in such underwriting and the inclusion of such Stockholder's
Common Stock in the underwriting to the extent provided herein.

         All Stockholders proposing to distribute their Common Stock through
such underwriting shall, together with HSNS and the other parties distributing
their securities through such underwriting, enter into an underwriting agreement
in customary form with the underwriter or underwriters selected for such
underwriting by HSNS. Notwithstanding any other provision of this PARAGRAPH
4.15, if the underwriter determines that marketing factors require a limitation
of the number of shares to be underwritten, the underwriter may limit the number
of Stockholder's Common Stock to be included in the registration and
underwriting, or may exclude Stockholder's Common Stock entirely from such
registration and underwriting subject to the terms of this Section 2.3. HSNS
shall so advise all holders of HSNS's securities that would otherwise be
registered and underwritten pursuant hereto, and the number of shares of such
securities, including Stockholder's Common Stock, that may be included in the
registration and underwriting shall be allocated in the following manner:
shares, other than Stockholder's Common Stock and other securities that have
contractual rights with respect to registration similar to those provided for in
this PARAGRAPH 4.15, requested to be included in such registration by
shareholders shall be excluded, and if a limitation on the number of shares is
still required, the number of Stockholder's Common Stock and other securities
that have contractual rights with respect to registration that may be included
shall be allocated among the holders thereof in proportion, as nearly as
practicable, to the amounts of Stockholder's Common Stock and such other
securities held by each such holder at the time of filing the Registration
Statement. For purposes of any such underwriter cutback, all Common Stock and
other securities held by any holder that is a partnership or corporation, shall
also include any


                                       12
<PAGE>   14

Stockholder's Common Stock and other securities held by the partners, retired
partners, shareholders or affiliated entities of such holder, or the estates and
family members of any such partners and retired partners and any trusts for the
benefit of any of the foregoing persons, and such holder and other persons shall
be deemed to be a single "selling holder," and any pro rata reduction with
respect to such "selling holder" shall be based upon the aggregate amount of
shares carrying registration rights owned by all entities and individuals
included in such "selling holder," as defined in this sentence. No securities
excluded from the underwriting by reason of the underwriter's marketing
limitation shall be included in such registration. Nothing in this SECTION
2.3(B) is intended to diminish the number of securities to be included by HSNS
in the underwriting.

         If any Stockholder disapproves of the terms of the underwriting, it may
elect to withdraw therefrom by written notice to HSNS and the underwriter. The
Stockholder's Common Stock so withdrawn shall also be withdrawn from
registration.

                  (c)      Right to Terminate Registration. HSNS shall have the
right to terminate or withdraw any registration initiated by it under this
PARAGRAPH 4.15 prior to the effectiveness of such registration whether or not
any Stockholder has elected to include securities in such registration.

         4.16     MARKET STAND-OFF AGREEMENT. Summus and each Stockholder agree
that none of the Common Stock included in the Share Purchase Price may be sold
in public market transactions during the twelve (12) months following the
Closing, provided that one and one-half percent (1.5%) of the shares included in
the Share Purchase Price (excluding those shares referred to in Paragraphs 9.12
and 9.13) may be sold or otherwise disposed of in each of the third through
twelfth months following Closing. Notwithstanding the foregoing, the sale
restriction shall not apply to Common Stock obtained through exercise of options
converted from agreements with Chris Gaertner for 2,500 Summus options, Stuart
Diamond for 10,000 Summus options, and Kenneth Marks for 5,000 Summus options.

         4.17     SALARIES RESERVE. HSNS agrees that for a period of twelve (12)
months following Closing, HSNS guarantees payment of the salaries of employees
acquired from Summus and listed on Schedule 3.2(b)(iv) so long as they remain
employed by HSNS. Throughout such twelve (12) month period, HSNS shall maintain
a reserve, in cash or cash equivalents, of at least $800,000 for the purpose of
paying such salaries.

         4.18     MODIFICATIONS TO SCHEDULES. Changes to Schedules may be made
by the parties prior to Closing by written agreement of the parties.

         4.19     RETIREMENT OF SHARES. Following Closing, HSNS shall retire the
8,239,360 shares of Common Stock purchased as part of the Acquired Assets, and
will retire the Common Stock (expected to be 3,111,293 shares) that HSNS
receives in distributions by Summus to its shareholders upon liquidation.

         4.20     CERTAIN OPTIONS. HSNS agrees that with regard to options on
Common Stock obtained through conversion of certain options on Summus stock held
by Chris Gaertner (2,500 Summus options), Stuart Diamond (10,000 Summus
options), and Kenneth Marks (5,000 Summus options), when the Company becomes
current on its reports required under the


                                       13
<PAGE>   15

Securities Exchange Act of 1934, and provided in each case that the person in
question is eligible to use such form, the Company shall file an Form S-8 with
regard to such options.

         STOCKHOLDERS AND SUMMUS

security agreement, loan agreement, guaranty, pledge, or other material
instrument, contract, agreement or commitment or any Order, to which Summus or
any Stockholder is a party or by


                                       15
<PAGE>   17

assets or properties, (x) the acceleration or creation of any Liability of
Summus, (y) the forfeiture of any right or privilege of Summus, or (z) the
forfeiture of any right or privilege of any Stockholder which may affect such
Stockholder's ability to perform under this Agreement, other than such Liens,
Liabilities or forfeitures that, individually or in the aggregate, would not
have a material adverse effect on the Acquired Business or prevent the
consummation of the transactions contemplated hereby.

         5.4      CONSENTS. Except as set forth in the Disclosure Memorandum,
the execution, delivery and performance by each Stockholder and Summus of this
Agreement and the Other Agreements to which he or it is a party, and the
consummation of the transactions contemplated herein and therein does not (a)
require the consent, approval or action of, or any filing with or notice to, any
Government or other Person by Summus or any Stockholder, or (b) impose any other
term, condition or restriction on HSNS pursuant to any business combination or
takeover Law, except where the failure to obtain such consent or the violation
of such restriction would not have a material adverse effect on the Acquired
Business.

         5.5      NO VIOLATION; COMPLIANCE WITH LAWS. Except as set forth in the
Disclosure Memorandum, Summus is not in default under or in violation of (a) its
articles of incorporation or bylaws or (b) any Order. Except as set forth in the
Disclosure Memorandum, the operations of Summus have been conducted in all
material respects in compliance with all applicable Laws. (For purposes of this
paragraph, any violation of applicable Law that could result in imposition of a
fine or other monetary penalty upon Summus in excess of $1,000 shall be deemed
to be a material non-compliance). Except as set forth in the Disclosure
Memorandum, neither Summus nor any Stockholder has received any notification of
any asserted past or present failure by Summus to comply with any applicable Law
other than any failure to comply that would not have a material adverse effect
on the Acquired Business.

         5.6      POSSESSION OF LICENSES. Except as set forth in the Disclosure
Memorandum, Summus possesses all franchises, certificates, licenses, permits and
other authorizations from Governments and all other Persons, that are necessary
for the ownership, maintenance and operation of its properties and assets and
the conduct of its business except where failure to have such franchises,
certificates, licenses, permits and other authorization would not have a
material adverse effect on the Acquired Business, and Summus is not in material
violation thereof.

         5.7      BOOKS AND RECORDS; FINANCIAL STATEMENTS, FINANCIAL CONDITION.
Prior to the date hereof, the Stockholders have delivered to HSNS copies of
Summus' financial statements and related documents, as amended, as identified in
the Disclosure Memorandum (collectively, the "FINANCIAL STATEMENTS"). The
Financial Statements include Summus' most recent Balance Sheet as of September
30, 2000, (the "REFERENCE DATE BALANCE SHEET"). The date of the Reference Date

         The Financial Statements (i) have been prepared from the books and
records of Summus in accordance with GAAP, (ii) reflect all Liabilities of the
Company required to be reflected therein on such basis as at the date thereof
and (iii) fairly present in all material respects the financial position of
Summus as of the respective dates of the balance sheets included in the
Financial Statements and the consolidated results of its operations for each of
the periods then ended. There has been no material adverse change since the
Balance Sheet Date in the amount


                                       16

machinery, equipment, vehicles, and other items of tangible personal property

         5.12     REAL PROPERTY.

                  (a)      Summus has good title to all of the real property
reflected on the Reference Date Balance Sheet as owned by Summus (collectively,
the "OWNED REAL PROPERTY"), free and clear from all defects and Liens, except as
may be set forth in the notes to the Reference Date Balance Sheet or in the
Disclosure Memorandum. The Disclosure Memorandum lists all Real Property,
whether or not owned by Summus, and provides the true and correct street address
and name of the owner or lessor of such Real Property.

                  (b)      Each parcel or tract of real property which is used
by Summus in its business and that is not Owned Real Property (the "LEASED REAL
PROPERTY," and collectively with the Owned Real Property, the "REAL PROPERTY")
is subject to a written lease or sublease to which Summus is a party as lessee
or sublessee (individually a "REAL PROPERTY LEASE"). All such Real Property
Leases are valid and in full force and effect in accordance with their terms.
The Stockholders have previously furnished HSNS with true, correct and complete
copies of all Real Property Leases. There is not, with respect to any Real
Property Lease (i) any material default by Summus, or any event of default or
event which with notice or lapse of time, or both, would constitute a material
default by Summus or (ii) to the knowledge of Summus, any existing material
default by any other party to any Real Property Lease, or event of default or
event which with notice or lapse of time, or both, would constitute a material
default by any other party to any Real Property Lease.

                  (c)      All of the Owned Real Property is free from
development, use or occupancy restrictions, except those imposed by applicable
Law, and from special taxes or assessments, except those generally applicable to
other properties in the tax districts in which the Owned Real Property is
located except where such restrictions or assessments would not have a material
adverse effect on the Acquired Business. No options have been granted to others
to purchase, lease or otherwise acquire any interest in the Owned Real Property.
Summus has the exclusive right of possession of each tract or parcel comprising
its Owned Real Property.

                  (d)      Except as set forth in the Disclosure Memorandum, the
present use, occupancy and operation of the Real Property, and all aspects of
the Improvements to the Real Property, are in material compliance with all Laws
and private restrictive covenants, and to Summus' knowledge there has not been
any proposed change thereto that would affect any of the Real Property or its
use, occupancy or operation. There exists no material conflict or dispute with
any Government or other Person relating to any Real Property or the activities
thereon. To the knowledge of Summus, no portion of the Real Property is subject
to any classification, designation or preliminary determination of any
Government or pursuant to any Law which would materially restrict its use,
development, occupancy or operation in connection with Summus' business. Except
as set forth in the Disclosure Memorandum, all Improvements are in good
condition and repair, and are suited for the operation of Summus' business.

                  (e)      Except as set forth in the Disclosure Memorandum,
neither Summus nor any other Person has caused any work or improvements to be
performed upon or made to any of the Real Property for which there remains
outstanding any payment obligation that would or might serve as the basis for
any Lien in favor of the Person who performed the work.

                  (f)      Except as set forth in the Disclosure Memorandum, all
requisite certificates of occupancy and other permits and approvals required
with respect to the Real Property or the Improvements and the use, occupancy and
operation thereof have been obtained and paid for and are currently in effect
and free of restrictions, except where the lack of such certificates or the
presence of such restrictions would not have a material adverse effect on the
Acquired Business.

                  (b)      The operation of the business of Summus as currently
conducted or as presently contemplated to be conducted and the use of Summus
Owned Intellectual Property and Summus Licensed Intellectual Property in
connection therewith do not infringe, misappropriate or otherwise violate the
Intellectual Property rights of any third party, and no Action is pending or, to
the knowledge of Summus, threatened alleging that the operation of such
business, or such use of Summus Owned Intellectual Property or Summus Licensed
Intellectual Property by Summus, does or may interfere with, conflict with,
infringe, misappropriate or otherwise violate the Intellectual Property rights
of any third party.

                  (c)      Except as set forth in the Disclosure Memorandum,
Summus is the sole and exclusive owner of the entire and unencumbered right,
title and interest in and to Summus Owned Intellectual Property and has the

                  (d)      Summus Owned Intellectual Property and Summus
Licensed Intellectual Property include all of the Intellectual Property used in
the ordinary course of the business of Summus, and there are no other items of
Intellectual Property that are material to such ordinary course of such
business. Summus Owned Intellectual Property and, to the knowledge of Summus,
any Intellectual Property licensed to Summus under Summus Licensed Intellectual
Property, are subsisting, valid and enforceable, and have not been adjudged
invalid or unenforceable in whole or in part.

                  (e)      No Actions have been asserted, are pending, or, to
the knowledge of Summus or the Stockholders, threatened against Summus (i) based
upon or challenging or seeking to deny or restrict the use by Summus of any of
Summus Owned Intellectual Property or Summus Licensed Intellectual Property,
(ii) alleging that any services provided by, processes used by, or products
manufactured or sold by Summus infringe or misappropriate any Intellectual

                  (f)      To the knowledge of Summus, no person is engaging in
any activity that infringes or misappropriates Summus Owned Intellectual
Property or Summus Licensed Intellectual Property. Except as set forth in the
Disclosure Memorandum, Summus has not granted any license or other right to any
third party with respect to Summus Owned Intellectual Property or Summus
Licensed Intellectual Property. The execution, delivery and performance of this
Agreement and the consummation of the transactions contemplated by this
Agreement by Summus will not breach, violate or conflict with any instrument or
agreement concerning Summus Owned Intellectual Property, except as set forth in
the Disclosure Memorandum, will not cause the forfeiture or termination or give
rise to a right of forfeiture or termination of any of Summus Licensed
Intellectual Property or impair the right of HSNS to make, use, sell, license or
dispose of, or to bring any action for the infringement of, any Summus Owned
Intellectual Property.

                  (g)      Summus has delivered or made available to HSNS
correct and complete copies of all the licenses of Summus Licensed Intellectual
Property. With respect to each such license:

                           (i)      To Summus' knowledge, such license is valid
and binding and in full force and effect and represents the entire agreement
between the respective licensor and Summus with respect to the subject matter of
such license;

                           (ii)     such license will not cease to be valid and
binding and in full force and effect on terms identical to those currently in
effect as a result of the consummation of the transactions contemplated by this
Agreement, nor will the consummation of the transactions contemplated by this
Agreement constitute a breach or default under such license or otherwise give
the licensor a right to terminate such license, except as set forth in the
Disclosure Memorandum;

                           (iii)    Summus has not (A) received any notice of
termination or cancellation under such license, (B) received any notice of
breach or default under such license,


                                       20
<PAGE>   22

which breach has not been cured, or (C) granted to any other third party any
rights, adverse or otherwise, under such license that would constitute a breach
of such license; and

                           (iv)     neither Summus, nor, to the knowledge of
Summus, any other party to such license is in material breach or default
thereof, and, to Summus' knowledge, no event has occurred that, with notice or
lapse of time, would constitute such a material breach or default or permit
termination, modification or acceleration under such license.

                  (h)      Summus Software intended for distribution to
customers is free of all viruses, worms, Trojan horses and other material known
contaminants, and to the knowledge of Summus does not contain any bugs, errors,
or problems of a material nature. Summus has obtained all approvals necessary
for exporting Summus Software outside the United States and importing Summus
Software into any country in which Summus Software is now sold or licensed for
use, and all such export and import approvals in the United States and
throughout the world are valid, current, outstanding and in full force and
effect, except where the failure to keep such approvals in effect would not have
a material adverse effect on Summus' business. Except as specified in the
Disclosure Memorandum, no rights in Summus Software have been transferred to any
third party except to the customers of Summus to whom Summus has licensed such
Summus Software in the ordinary course of business. Except as described in the
Disclosure Memorandum, none of Summus Software is licensed pursuant to an "open
source" or "GNU" license, or incorporates or is based on any Software that is
licensed pursuant to an "open source" or "GNU" license.

                  (i)      Summus has the right to use all software development

material and necessary to the business of Summus, or that is required to operate
or modify Summus Software.

                  (j)      Summus has taken reasonable steps in accordance with
normal industry practice to maintain the confidentiality of its trade secrets
and other confidential Intellectual Property. To the knowledge of Summus, (i)
there has been no misappropriation of any material trade secrets or other
material confidential Summus Owned Intellectual Property or Summus Licensed
Intellectual Property by any person; (ii) no employee, independent contractor or
agent of Summus has misappropriated any trade secrets of any other person in the
course of such performance as an employee, independent contractor or agent of
Summus; and (iii) no employee, independent contractor or agent of Summus is in
default or breach of any term of any employment agreement, non-disclosure
agreement, assignment of invention agreement or similar agreement or contract
relating in any way to the protection, ownership, development, use or transfer
of Summus Owned Intellectual Property or Summus Licensed Intellectual Property.

                  (k)      Summus Software, and every portion thereof, was
authored (i) by an employee or employees of Summus working within the scope of
their employment such that the contribution of such employee or employees to
Summus Software constitutes a "work made for hire" as that term is defined under
U.S. Copyright Law or (ii) by a person that has executed a written assignment
assigning all right, title, and interest in and to the portion of the software
authored by that person to Summus, and Summus has provided copies of all such
written assignments to HSNS. Summus has provided HSNS with (i) a complete
history of development of the source code of Summus Software, including all
versions thereof and modifications thereto, (ii) a list of all software tools,
library functions, and other software developed by Summus or by any third party
that is or was utilized in the development of Summus Software or that is
required


                                       21
<PAGE>   23

to operate or modify Summus Software and (iii) a description of the location and
custodian of all such source code, software tools, library functions, and other
software. All such source code, software tools, library functions, and other
software, is in the possession of Summus. Summus has the right to use such
source code, software tools, library functions, and other software to the extent
necessary to conduct and to continue to conduct the Business, and Summus has
provided HSNS with copies of all written agreements concerning the right to use
such source code, software tools, library functions, and other software.

                  (l)      SUMMUS AND THE STOCKHOLDERS MAKE NO REPRESENTATIONS,
EXPRESS OR IMPLIED, REGARDING THE PERFORMANCE OF THE SUMMUS SOFTWARE, SUMMUS
LICENSED INTELLECTUAL PROPERTY OR SUMMUS OWNED INTELLECTUAL PROPERTY INCLUDING,
WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE, AND HEREBY DISCLAIM SUCH WARRANTIES.

                  (m)      There have been no transfers of intellectual property
owned or developed by Summus since January 1, 2000, except licenses by Summus
included in the Acquired Contracts.

         5.14     CONTRACTS.

                  (a)      Except as set forth in the Disclosure Memorandum, all
Acquired Contracts have been entered into in the ordinary course of Summus'
business, are valid and enforceable in all material respects in accordance with
their terms, are in full force and effect, and will continue to be valid and
enforceable and in full force and effect on identical terms following the date
of the Closing. Assuming that each such Acquired Contract is completed by HSNS
in a manner that consistent with Summus' historical business practices, no
Acquired Contract is likely to result in a loss to Summus upon completion of
performance and all Acquired Contracts can be materially fulfilled or performed
by Summus in accordance with their respective terms without undue or unusual
expenditures of money or effort. All Acquired Contracts are listed on the
Disclosure Memorandum, and true, correct and complete copies of all Acquired

                  (b)      Except as set forth on the Disclosure Memorandum, to
the knowledge of Summus and the Stockholders, there are no existing material
defaults, events of default or events which, with the giving of notice or lapse
of time, or both, would constitute a material default by Summus under any
Acquired Contract. To the knowledge of Summus and the Stockholders, no event has
occurred which may hereafter give rise to any right of termination,
acceleration, damages or any other remedy under any Acquired Contract.

                  (c)      Except as set forth on the Disclosure Memorandum, to
Summus' and the Stockholders' knowledge, neither this Agreement, the Closing or
the relationship between Summus and HSNS has caused or is likely to cause the
termination or nonrenewal of any Acquired Contract.

         5.15     INSURANCE. Summus has obtained and maintains insurance
policies which it believes provide adequate coverage to insure its assets,
properties and business, and all such policies are in full force and effect.
Except as set forth on the Disclosure Memorandum, all premiums due on such

with respect thereto. Except for workers' compensation premiums that have not
yet


                                       22
<PAGE>   24

been determined, Summus has no Liability for premiums or for retrospective

Disclosure Memorandum, no Action is pending or, to the knowledge of the
Stockholders and Summus, threatened against, by or affecting Summus or the
Acquired Assets. There are no unsatisfied judgments or Orders against Summus to
which it or its assets and properties are subject.

         5.17     TAXES. Except as set forth in the Disclosure Memorandum,
Summus and any entity at any time eligible or required to file a consolidated or

federal, state, municipal, local and foreign, if any, Tax returns and reports
(including returns for estimated tax), and all reports and returns of all other
Governments having jurisdiction (collectively, "RETURNS") with respect to all

some or all of Summus and the Affiliated Entities); all such Tax returns and
reports show the correct and proper amount due; and the Taxes shown on all Tax
returns and reports and all Tax assessments received by Summus or any Affiliated
Entities have been paid to the extent that such Taxes or estimates are due.
Except as set forth in the Disclosure Memorandum, Summus has previously provided
to HSNS true, correct and complete copies of all Returns filed since inception.
Except as set forth on the Disclosure Memorandum, all Taxes imposed on Summus
and its Affiliated Entities by any Government (including all deposits in
connection therewith required by applicable Law, and all interest and penalties
thereon) which have become due and payable by Summus for all periods through the
date hereof have been paid in full, and adequate reserves for all other Taxes,
whether or not due and payable, and whether or not disputed, have been set up on
the books of Summus, and such reserves will be adequate to pay all Taxes of
Summus for all periods through the Closing. Except as set forth on the
Disclosure Memorandum, to the knowledge of Summus, there is not now any proposed
assessment against Summus or any Affiliated Entity of additional Taxes of any
kind. Summus is not a party to any Tax sharing or Tax allocation agreement,

which deals with wages, conditions of employment, benefits or other matters
affecting the employer/employee relationship with any union, labor organization

Stockholders' knowledge threatened, between Summus and any union, labor
organization or employee group representing, or seeking to represent, any of its
employees, and there has been no attempt by any union, labor organization or
employee group to organize any of Summus' employees at any time in the past five
years. Except as set forth in the Disclosure Memorandum, Summus has
substantially complied with all applicable Laws relating


                                       23
<PAGE>   25

to wages, hours, health and safety, payment of social security withholding and
other taxes, maintenance of workers' compensation insurance, labor and
employment relations and employment discrimination except where such failure
would not have a material adverse effect on the Acquired Business.

                  (c)      The Disclosure Memorandum lists all contracts,
agreements or arrangements (written or oral) concerning the employment of any
individual by Summus, including each such individual's title, compensation and
duties other than any contracts, agreements or arrangements (written or oral)
that are not, individually or in the aggregate, material in amount.

         5.19     EMPLOYEE BENEFIT MATTERS.

                  (a)      The Disclosure Memorandum lists all "employee benefit
plans" within the meaning of Section 3(3) of Employee Retirement Income Security
Act of 1974, as amended ("ERISA") to which Summus contributes or is required to
contribute (the "SUMMUS PLANS") and all other material practices, commitments,
arrangements and agreements pursuant to which Summus provides, directly or
indirectly, any benefits for employees. Summus is not required to contribute,
and has never been required to contribute, to any multi-employer plan within the

                  (b)      Each Summus Plan has been operated and administered
in all material respects in accordance with all applicable Laws, including,
without limitation, ERISA and the Code except where the failure to comply with
such Laws would not have a material adverse effect on the Acquired Business. To
the knowledge of Summus and the Stockholders after due inquiry, each Summus Plan
that is a group health plan within the meaning of Section 607(1) of ERISA and
Section 4980B of the Code has complied and is in compliance in all material
respects with the continuation coverage requirements of Section 601 of ERISA and
Section 4980B of the Code. There are no pending claims or, to Summus' and the
Stockholders' knowledge threatened claims, by or against any of Summus Plans by
any employee or beneficiary covered under such Summus Plan, or by any Government
or otherwise involving such Summus Plan or any of its fiduciaries (other than
for routine claims for benefits).

                  (c)      The Disclosure Memorandum separately identifies any
Summus Plan that is an "employee pension benefit plan" within the meaning of
Section 3(2) of ERISA ("SUMMUS PENSION PLAN") and also lists any "employee
pension benefit plan" within the meaning of Section 3(2) of ERISA formerly
sponsored by Summus which has been terminated during the last 5 years. All
Summus and employee contributions required to be made to each Summus Pension
Plan have been made in a timely manner.

to provide, and Summus does not provide, benefits, including, without
limitation, death, health or medical benefits (whether or not insured), with
respect to current or former employees of Summus beyond their retirement or

Law. Neither this Agreement nor any transaction contemplated hereby will entitle
any current or former employee, officer or director of Summus to severance pay,
unemployment


                                       24

other handling of Hazardous Materials from any Real Property, will subject
Summus to corrective or compliance action or any other Liability. There are no
presently pending, or to Summus' and the Stockholders' knowledge, threatened
Actions or Orders against or involving Summus (including any Person for whose
acts or omissions Summus is responsible) relating to any alleged, past or

foregoing being collectively referred to as the "SEC DOCUMENTS"). As of their
respective filing dates, the SEC Documents complied in all material respects
with the requirements of the Securities Exchange Act of 1934 (the "EXCHANGE
ACT"), and none of the SEC Documents contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements made therein, in light of the circumstances
in which they were made, not misleading, except to the extent corrected by a

principles consistently applied (except as may be indicated in the notes thereto
or, in the case of unaudited statements, as permitted by Form 10-Q of the SEC),
present fairly the consolidated financial position of HSNS at the dates thereof
and the consolidated results of its operations and cash flows for the periods
then ended (subject, in the case of unaudited statements, to normal audit
adjustments), and reflect all Liabilities of HSNS required to be reflected
therein in accordance with GAAP as at the date thereof. There has been no change
in HSNS accounting policies except as described in the notes to the HSNS
Financial Statements; provided, however, HSNS may have restated or may restate
one or more of the HSNS Financial Statements to reflect acquisitions entered
into subsequent to the respective dates thereof. Since the date of the HSNS
Financial Statements, there has not been a material increase in the Liabilities
of HSNS and there has been no material adverse change in the financial condition
of HSNS, other than expenditure of funds and incurring of debt in the normal
course of business.

         7.1      INDEMNIFICATION AND PAYMENT OF INDEMNIFIED LOSSES BY SUMMUS.

                  (a)      In accordance with and subject to the provisions of
this Article 7, Summus hereby agrees to indemnify and hold harmless HSNS, its
Affiliates, and the officers, directors, and agents of HSNS, and their
Affiliates (collectively, the "HSNS INDEMNITEES") from and against, and will pay
to the HSNS Indemnitees the amount of any loss, liability, claim, damage, cost
or expense (including reasonable costs of investigation and defense and
reasonable attorneys' and experts' fees and expenses and amounts paid in
settlement) or diminution of value, whether or not involving a third-party claim
(collectively, the "INDEMNIFIED LOSSES"), arising, directly or indirectly, from
or in connection with or incurred as a result of:

                           (i)      any breach of any representation or warranty
made by Summus or the Stockholders in this Agreement, the Disclosure Memorandum
or in any certificate delivered by Summus or the Stockholders pursuant to this
Agreement; or

                           (ii)     any breach by Summus or the Stockholders of
any covenant or obligation of Summus or the Stockholders in this Agreement; or

                           (iii)    any obligation of Summus that was not an
Assumed Liability.

                  (b)      Notwithstanding any provision herein to the contrary,
Summus (and not the Stockholders) shall be solely responsible for
indemnification under this Section 7.1. Furthermore, Summus shall not have any
obligation to indemnify the HSNS Indemnitees for any Indemnified Losses
resulting from the breach or breaches of any representation or warranty of
Summus or the Stockholders contained in this Agreement or in the Disclosure
Memorandum or in any certificate relating thereto and delivered by Summus or the
Stockholders pursuant to this Agreement: (i) until the HSNS Indemnitees have
suffered Indemnified Losses, by reason of such breach or breaches, in excess of
$25,000 in the aggregate (the "SUMMUS BASKET"); provided that once the HSNS
Indemnitees' aggregate Indemnified Losses exceed the Summus Basket, Summus shall
indemnify the HSNS Indemnitees for all such Indemnified Losses suffered, and
(ii) to the extent that the aggregate Indemnified Losses the HSNS Indemnitees
have suffered by reason of all such breaches of representations and warranties
of Summus and the Stockholders exceed the value of the Escrowed Shares (the
"SUMMUS CAP"), in the absence of fraud or


                                       30
<PAGE>   32

intentional misrepresentation, Summus and the Stockholders will have no
obligation to indemnify the HSNS Indemnitees for further Indemnified Losses in
excess of the Summus Cap. Such indemnification shall be payable by Summus
exclusively by relinquishing that number of the Escrowed Shares to HSNS equal to
the amount of such Indemnified Losses (subject to the Summus Cap) divided by the
Market Price of the Escrowed Shares.

         7.2      INDEMNIFICATION AND PAYMENT OF LOSSES BY HSNS.

                  (a)      In accordance with and subject to the provisions of
this Article 7, HSNS hereby agrees to indemnify and hold harmless Summus, its
Affiliates, and the officers, directors, and agents of Summus, and their
Affiliates (collectively, the "SUMMUS INDEMNITEES") from and against, and will
pay to the Summus Indemnitees the amount of any Indemnified Losses, arising,
directly or indirectly, from or in connection with or incurred as a result of:

                           (i)      any breach of any representation or warranty
made by HSNS in this Agreement, the Disclosure Memorandum or in any certificate
delivered by HSNS pursuant to this Agreement; and

                           (ii)     any breach by HSNS of any covenant or
obligation of HSNS in this Agreement.

                  (b)      Notwithstanding anything in this PARAGRAPH 7.2(B) to
the contrary, HSNS shall have no obligation to indemnify the Summus Indemnitees
for any Indemnified Losses resulting from the breach or breaches of any
representation or warranty of HSNS contained in this Agreement or in the
Disclosure Memorandum or in any certificate relating thereto and delivered by
Summus or the Stockholders pursuant to this Agreement: (i) until the Summus
Indemnitees have suffered Indemnified Losses, by reason of such breach or
breaches, in excess of $25,000 in the aggregate (the "HSNS BASKET"); provided
that once the Summus Indemnitees' aggregate Indemnified Losses exceed the HSNS
Basket, HSNS shall indemnify the Summus Indemnitees for all such Indemnified
Losses suffered, and (ii) to the extent that the aggregate Indemnified Losses
the Summus Indemnitees have suffered by reason of all such breaches of
representations and warranties of HSNS exceed the value of 2,000,000 shares of
Common Stock (the "HSNS CAP"), in the absence of fraud or intentional
misrepresentation, HSNS will have no obligation to indemnify the Summus
Indemnitees for further Indemnified Losses in excess of the HSNS Cap. Such
indemnification shall be payable by HSNS exclusively by issuing an additional
number of shares of Common Stock to Summus equal to the amount of such
Indemnified Losses (subject to the HSNS Cap) divided by the Market Price of the
Common Stock.

         7.3      SURVIVAL.

                  (a)      The representations and warranties of each
Stockholder and Summus contained in this Agreement, any Other Agreement, the
Disclosure Memorandum or in any certificate, instrument, agreement or other
writing delivered by or on behalf of any Stockholder or Summus pursuant to this
Agreement or in connection with the transactions contemplated herein are made as
of the date of this Agreement and shall survive the consummation of the
transactions contemplated herein and all such representations and warranties
shall be of no further force and effect after the expiration of one (1) year
from the date of the Closing (the "SURVIVAL PERIOD"); provided, however, that
the Survival Period shall not apply to the representations, warranties,
covenants, agreements and indemnifications set forth in PARAGRAPH


                                       31
<PAGE>   33

5.17, PARAGRAPH 5.19 and PARAGRAPH 5.20 hereof, which shall survive for the
applicable statute of limitations on claims by third parties.

                  (b)      The representations and warranties of HSNS contained
in this Agreement, any Other Agreement, or in any certificate, instrument,
agreement or other writing delivered by or on behalf of HSNS pursuant to this
Agreement or in connection with the transactions contemplated herein shall
survive any investigation heretofore or hereafter made by or on behalf of Summus
and the Stockholders and the consummation of the transactions contemplated
herein and all such representations and warranties shall be of no further force
and effect after the expiration the Survival Period.

                  (c)      Anything to the contrary notwithstanding, a claim for
indemnification which is made but not resolved prior to the expiration of either
the Survival Period, as applicable, may be pursued and resolved after such
expiration. Anything in this PARAGRAPH 7.5 to the contrary notwithstanding,
Summus shall remain liable, during the Survival Period and thereafter, for all
liabilities and obligations of Summus not assumed pursuant to PARAGRAPH 2.2,
including, without limitation, the Excluded Liabilities specified in PARAGRAPH
2.3.

         7.4      PROCEDURE FOR INDEMNIFICATION - THIRD-PARTY CLAIMS.

                  (a)      An indemnified party shall promptly give notice to
each indemnifying party after obtaining knowledge of any matter as to which
recovery may be sought against such indemnifying party because of the indemnity
set forth above, and, if such indemnity shall arise from the claim of a third
party, shall permit such indemnifying party to assume the defense of any such
claim or any Proceeding resulting from such claim; provided, however, that
failure to promptly give any such notice shall not affect the indemnification
provided under this PARAGRAPH 7 except to the extent such indemnifying party
shall have been actually and materially prejudiced as a result of such failure.
Notwithstanding the foregoing, an indemnifying party may not assume the defense
of any such third-party claim or Proceeding if it does not demonstrate to the
reasonable satisfaction of the indemnified party that it has adequate financial
resources to defend such claim or Proceeding and pay any and all damages that
may result therefrom, or if the claim or Proceeding (i) could result in
imprisonment of the indemnified party, (ii) could result in a criminal penalty
or fine against the indemnified party the consequences of which would be
reasonably likely to have a Material Adverse Effect on the indemnified party
unrelated to the size of such penalty or fine or (iii) could result in an
equitable remedy which would materially impair the indemnified party's ability
to exercise its rights under this Agreement, or impair HSNS's right or ability
to operate the Acquired Business. If an indemnifying party assumes the defense
of such third party claim or Proceeding, such indemnifying party shall agree
prior thereto, in writing, that it is liable under this PARAGRAPH 7 to indemnify
the indemnified party in accordance with the terms contained herein in respect
of such claim or Proceeding, shall conduct such defense diligently, shall have
full and complete control over the conduct of such claim or Proceeding on behalf
of the indemnified party and shall, in his or her or its sole discretion, have
the right to decide all matters of procedure, strategy, substance and settlement
relating to such claim or Proceeding; provided, however, that any counsel chosen
by such indemnifying party to conduct such defense shall be reasonably
satisfactory to the indemnified party. The indemnified party may participate in
such claim or Proceeding and retain separate co-counsel at its sole cost and
expense (except that the indemnifying party shall be responsible for the
reasonable fees and expenses of one separate co-counsel for the indemnified
party to the extent the indemnified party is advised by its counsel that the
counsel the


                                       32
<PAGE>   34

indemnifying party has selected has a conflict of interest) and the
indemnifying party will not without the written consent of the indemnified party
consent to the entry of any judgment or enter into any settlement with respect
to the matter which does not include a provision whereby the plaintiff or the
claimant in the matter releases the indemnified party from all liability with
respect thereto. Failure by an indemnifying party to notify the indemnified
party of its election to defend any such claim or Proceeding by a third party
within thirty (30) days after notice thereof shall have been given to such
indemnifying party by the indemnified party shall be deemed a waiver by such
indemnifying party of its right to defend such claim or Proceeding.

                  (b)      If no indemnifying party is permitted or elects to
assume the defense of any such claim or Proceeding by a third party, the
indemnified party shall diligently defend against such claim or Proceeding in
such manner as it may deem appropriate and, in such event, the indemnifying
party or parties shall promptly reimburse the indemnified party for all
reasonable out-of-pocket costs and expenses, legal or otherwise, incurred by the
indemnified party and its affiliates in connection with the defense against such
claim or Proceeding, a such costs and expenses are incurred. Any counsel chosen
by such indemnified party to conduct such defense must be reasonably
