  AGREEMENT by and among Summus, Inc. (USA), a Florida corporation (the “Company”),
  and the holder of the Company’s Common Stock whose name is set forth on the
  signature page to this Agreement (“Selling Shareholder”).

  W I T N E S S E T H:

              WHEREAS,
  the Company has sold shares of its Common Stock to the Selling Shareholder
  under a Subscription Agreement dated [Enter date]
  (the “Subscription
  Agreement”); and

              WHEREAS,
  in connection with the Subscription Agreement and Warrant to Purchase Shares
  of Common Stock dated the date hereof (the “Warrant”), the Company intends
  to register certain shares of the Company’s Common Stock and the Selling
  Shareholder desires that the Company register certain shares, as set forth on
  Schedule 1 hereto, of the Company’s Common Stock held or to be held by
  Selling Shareholder (the “Shares”) in such registration; and

              NOW
  THEREFORE, in consideration of the premises and the mutual terms and
  provisions hereof, the parties hereto hereby agree as follows:

             
  1.         Definitions. 
  For purposes of this Agreement, the following terms shall have the following
  respective meanings:

             
  (a)        “Act” shall mean the
  Securities Act of 1933, as amended, or any similar federal statute enacted
  hereafter, and the rules and regulations of the Commission thereunder, all as
  the same shall be in effect from time to time.

             
  (b)        “Commission” shall mean the
  Securities and Exchange Commission or any other federal agency at the time
  administering the Act.

             
  (c)        The terms “register,” “registered”
  and “registration” refer to a registration effected by preparing and
  filing a registration statement in compliance with the Act and the declaration
  or ordering of effectiveness of such registration statement by the Commission.

             
  2.         Registration. 
  The Company shall register the Shares set forth on Schedule 1 pursuant to a
  registration statement on Form S-1 covering the resale of certain shares of
  the Company’s Common Stock and that the Company is in the process of filing.
  The Selling Shareholder acknowledges and understands that: (i) the Company
  shall register only the Shares as set forth on Schedule 1 hereto in
  fulfillment of its obligations to register the Selling Shareholder’s
  securities under this Agreement or any agreement; and (ii) the Company shall
  be under no additional obligation to register any other securities of the
  Company held by Selling Shareholder, including, without limitation, options or
  other rights of the Selling Shareholder to acquire securities of the Company.

   

  

  
     
  

             
  3.         Furnish Information. 
  The Selling Shareholder shall furnish to the Company such information
  regarding Selling Shareholder, Selling Shareholder’s officers, directors,
  shareholders, family members, and affiliates, as applicable, the Shares and
  the intended method of disposition of the Shares as the Company shall
  reasonably request and as shall be required in connection with the action to
  be taken by the Company. 

             
  4.         Suspension of
  Disposition of Shares.  Selling Shareholder agrees that, upon receipt
  of any notice from the Company, of (a) the happening of any event as a result
  of which the prospectus included in such registration statement contains an
  untrue statement of a material fact or omits any fact necessary to make the
  statements therein not misleading, (b) any requests by the Commission for
  amendments or supplements to the registration statement or the prospectus or
  for additional information, (c) the issuance of any stop order suspending the
  effectiveness of the registration statement, (d) the information in the
  registration statement no longer being sufficient to permit continued sales
  under the registration statement, or (e) the receipt by the Company of any
  notification with respect to the suspension of the qualification of the Shares
  for sale in any jurisdiction, Selling Shareholder will forthwith discontinue
  disposition of the Shares until the Company notifies the Selling Shareholder
  in writing that sales of Shares may continue.  If so directed by the
  Company, such Selling Shareholder will deliver to the Company (at the expense
  of the Company) all copies, other than permanent file copies then in such
  Selling Shareholder’s possession, of the prospectus covering such Shares
  current at the time of receipt of such notice.

             
  5.         Expenses of Registration. 
  All reasonable expenses, other than underwriting discounts and commissions,
  incurred in connection with registrations, filings or qualifications pursuant
  to Section 2, including, without limitation, all registration, listing and
  qualification fees, printers and accounting fees and the fees and
  disbursements of counsel for the Company shall be borne by the Company. 
  The Selling Shareholder shall bear the fees and disbursements of its own
  counsel.

             
  6.         Limitation of the
  Company’s Obligations.  The Company shall not be obligated under
  this Agreement to register or include in any registration Shares that Selling
  Shareholder has requested to be registered if the Company shall furnish
  Selling Shareholder with a written opinion of counsel reasonably satisfactory
  to Selling Shareholder, that all Shares that Selling Shareholder holds may be
  publicly offered, sold and distributed without registration under the Act
  pursuant to Rule 144 promulgated by the Commission under the Act without
  restriction as to the amount of securities that can be sold.

             
  7.         Indemnification.

                         
  (a)        Except in the case of a sale by
  Selling Shareholder in violation of Section 4 hereof, the Company agrees to
  indemnify and hold harmless Selling Shareholder, its directors, its officers
  and each person, if any, who controls any Selling Shareholder within the
  meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and
  against any and all losses, claims, damages, liabilities and judgments
  (including, without limitation, any reasonable legal or

  2

  

  
     
  

  other expenses
  incurred in connection with investigating or defending any matter, including
  any action, that could give rise to any such losses, claims, damages,
  liabilities or judgments) caused by any untrue statement or alleged untrue
  statement of a material fact contained in the registration statement filed by
  the Company pursuant to Section 2, including any preliminary prospectus or
  final prospectus contained therein (or any amendment thereto), 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, liabilities or judgments are
  caused by any such untrue statement or omission or alleged untrue statement or
  omission based upon information relating to any Selling Shareholder furnished
  in writing to the Company by such Selling Shareholder expressly for use
  therein.

                         
  (b)        Selling Shareholder agrees to
  indemnify and hold harmless the Company, its directors, its officers and each
  person, if any, who controls the Company within the meaning of Section 15 of
  the Act or Section 20 of the Exchange Act, from and against any and all
  losses, claims, damages, liabilities and judgments (including, without
  limitation, any legal or other expenses incurred in connection with
  investigating or defending any matter, including any action, that could give
  rise to any such losses, claims, damages, liabilities or judgments) caused by
  any untrue statement or alleged untrue statement of a material fact contained
  in the registration statement filed pursuant to Section 2, including any
  preliminary prospectus or final prospectus contained therein (or any amendment
  thereto), 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, but only with respect to losses, claims,
  damages, liabilities and judgments caused by an untrue statement or omission
  or alleged untrue statement or omission based on information relating to such
  Selling Shareholder furnished in by or on behalf of such Selling Shareholder
  expressly for use in the registration statement filed pursuant to Section 2,
  including any preliminary prospectus or final prospectus contained therein (or
  any amendment thereto).

                         
  (c)        In case any action shall be
  commenced involving any person in respect of which indemnity may be sought
  pursuant to Sections 7(a) and 7(b) (the “Indemnified Party”), the
  indemnified party shall promptly notify the person against whom such indemnity
  may be sought (the “Indemnifying Party”) in writing and the Indemnifying
  Party shall assume the defense of such action, including the employment of
  counsel reasonably satisfactory to the Indemnified Party and the payment of
  all reasonable fees and expenses of such counsel, as incurred.  Any
  Indemnified Party shall have the right to employ separate counsel in any such
  action and participate in the defense thereof, but the fees and expenses of
  such counsel shall be at the expense of the Indemnified Party unless (i) the
  employment of such counsel shall have been specifically authorized in writing
  by the Indemnifying Party, (ii) the Indemnifying Party shall have failed to
  assume the defense of such action or employ counsel reasonably satisfactory to
  the Indemnified Party or (iii) the named parties to any such action (including
  any impleaded parties) include both the Indemnified Party and the Indemnifying
  Party, and the Indemnified Party shall have been advised by such counsel that
  there may be one or more legal defenses available to it which are different
  from or additional to those available to the Indemnifying Party (in which case
  the Indemnifying Party shall not have the right to assume the defense of such
  action on behalf of the Indemnified Party).  In any such case, the
  Indemnifying Party shall not, in connection with any one action or separate
  but substantially similar or related actions in the same jurisdiction arising
  out of

  3

  

  
     
  

  the same general allegations or circumstances, be liable for (i) the
  reasonable fees and expenses of more than one separate firm of attorneys (in
  addition to any local counsel) for (x) the Company, its directors, its
  officers and all persons, if any, who control the Company within the meaning
  of either such Section, and (iii) the reasonable fees and expenses of more
  than one separate firm of attorneys (in addition to any local counsel) for the
  Selling Shareholders, and all such fees and expenses shall be reimbursed as
  they are incurred.  The Indemnifying Party shall indemnify and hold
  harmless the Indemnified Party from and against any and all losses, claims,
  damages, liabilities and judgments by reason of any settlement of any action (i)
  effected with its written consent or (ii) effected without its written consent
  if the settlement is entered into more than twenty business days after the
  Indemnifying Party shall have received a written request from the Indemnified
  Party for reimbursement for the fees and expenses of counsel (in any case
  where such fees and expenses are at the expense of the Indemnifying Party)
  and, prior to the date of such settlement, the Indemnifying Party shall have
  failed to comply with such reimbursement request. No Indemnifying Party shall,
  without the prior written consent of the Indemnified Party, effect any
  settlement or compromise of, or consent to the entry of judgment with respect
  to, any pending or threatened action in respect of which the Indemnified Party
  is or could have been a party and indemnity or contribution may be or could
  have been sought hereunder by the Indemnified Party, unless such settlement,
  compromise or judgment (i) includes an unconditional release of the
  Indemnified Party from all liability on claims that are or could have been the
  subject matter of such action and (ii) does not include a statement as to or
  an admission of fault, culpability or a failure to act, by or on behalf of the
  Indemnified Party.

                         
  (d)        To the extent the
  indemnification provided for in this Section 8 is unavailable (other than in
  accordance with the terms hereof) to an Indemnified Party or insufficient in
  respect of any losses, claims, damages, liabilities or judgments referred to
  therein, then each Indemnifying Party, in lieu of indemnifying such
  Indemnified Party, shall contribute to the amount paid or payable by such
  Indemnified Party as a result of such losses, claims, damages, liabilities and
  judgments (i) in such proportion as is appropriate to reflect the relative
  benefits received by the Indemnifying Party or parties on the one hand and the
  Indemnified Party or parties on the other hand from the offering of the Shares
  or (ii) if the allocation provided by clause 7(d)(i) above is not permitted by
  applicable law, in such proportion as is appropriate to reflect not only the
  relative benefits referred to in clause 7(d)(i) above but also the relative
  fault of the Indemnifying Party or parties on the one hand and the Indemnified
  Party or parties on the other hand in connection with the statements or
  omissions which resulted in such losses, claims, damages, liabilities or
  judgments, as well as any other relevant equitable considerations.  The
  relative fault of the Company and the Selling Shareholder shall be determined
  by reference to, among other things, whether the untrue or alleged untrue
  statement of a material fact or the omission or alleged omission to state a
  material fact relates to information supplied by the Company or the Selling
  Shareholder, and the parties’ relative intent, knowledge, access to
  information and opportunity to correct or prevent such statement or
  omission.  The amount paid or payable by an Indemnified Party as a result
  of the losses, claims, damages, liabilities or judgments referred to in the
  immediately preceding paragraph shall be deemed to include, subject to the
  limitations set forth above, any reasonable legal or other expenses incurred
  by such Indemnified Party in connection with investigating or defending any
  matter, including any action, that could have given rise to such losses,
  claims, damages, liabilities or judgments.  No person

  4

  

  
     
  

  guilty of
  fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
  shall be entitled to contribution from any person who was not guilty of such
  fraudulent misrepresentation. 

                         
  (e)        The remedies provided for in
  this Section 7 are not exclusive and shall not limit any rights or remedies
  which may otherwise be available to any Indemnified Party at law or in equity.

             
  8.         Agreements of the
  Selling Shareholder. Selling Shareholder agrees, whether or not the
  transactions contemplated in this Agreement are consummated or this Agreement
  is terminated, to pay or cause to be paid all reasonable expenses incident to
  the performance of the Selling Shareholder’s obligations under this
  Agreement, including: (i) the fees, disbursements and expenses of Selling
  Shareholder’s counsel in connection with the registration and delivery of
  the Shares under the Act, (ii) all costs and expenses related to the transfer
  and delivery of the Shares, including any transfer or other taxes payable
  thereon, and (iii) all other costs and expenses incident to the performance of
  the obligations of the Selling Shareholder hereunder for which provision is
  not otherwise made in this Section.  The provisions of this Section shall
  not supersede or otherwise affect any separate agreement that the Company and
  any Selling Shareholder may have for allocation of such expenses among
  themselves.

             
  9.         Amendments and Waivers.
  The provisions of this Agreement, including the provisions of this sentence,
  may be amended, modified or supplemented, and waivers or consents to
  departures from the provisions hereof may be given, by written consent of the
  Company and the Selling Shareholder.

  2.1       Dividends in Stock Adjustment. 
  In case, at any time or from time to time on or after the date hereof, the

  time receivable upon the exercise of this Warrant) shall have received, or, on
  or after the record date fixed for the determination of eligible stockholders,
  shall have become entitled to receive, without payment therefor, other or
  additional securities or other property (other than cash) of the Company by

  to the number of Warrant Shares receivable thereupon, and without payment of

  period from the date thereof to and including the date of such exercise,
  retained such shares and/or all other additional securities or other property
  receivable by it as aforesaid during such period, giving effect to all
  adjustments called for during such period by this subsection 2.1 and
  subsections 2.2 and 2.3 of this Section 2.

  would have been entitled upon such consummation if such holder had exercised
  this Warrant immediately prior thereto, all subject to further adjustment as
  provided in subsections 2.1 and 2.3 of this Section 2.

                         
  2.3       Stock Splits and Reverse Stock
  Splits.  If, at any time on or after the date hereof, the Company
  shall subdivide its outstanding shares of Common Stock into a greater number
  of shares, the Warrant Price in effect immediately prior to such subdivision
  shall thereby be proportionately reduced and the number of shares receivable
  upon exercise of this Warrant

  2

  

  
     
  

  shall thereby be proportionately increased; and,
  conversely, if, at any time on or after the date hereof, the outstanding
  number of shares of Common Stock shall be combined into a smaller number of
  shares, the Warrant Price in effect immediately prior to such combination
  shall thereby be proportionately increased and the number of shares receivable
  upon exercise of this Warrant shall thereby be proportionately decreased.

             
  3.         No Fractional Shares. 
  No fractional shares will be issued in connection with any exercise of this
  Warrant hereunder.  In lieu of any fractional shares that would otherwise
  be issuable, the Company shall pay cash equal to the product of such fraction
  multiplied by the Fair Market Value of one share issuable under the Warrant on
  the date of exercise, less the portion of the Exercise Price attributable to
  such fraction.

              For
  purposes hereof, the “Fair Market Value” of a share of Common Stock shall
  mean, as of any specific date of determination (the “Determination Date”):

             
  (a)        the price per share of such
  Common Stock equal to the average of the last sale price of such Common Stock
  on each of the ten trading days prior to the Determination Date on the
  principal national securities exchange on which the Common Stock may at the
  time be listed, or, if there shall have been no sales on such exchange on any
  such trading day, the average of the closing bid and asked prices on such
  exchange on such trading day;

             
  (b)        if the Common Stock is not
  listed on national securities exchange, the average of the closing sales
  prices as reported by Nasdaq at the end of each of the ten trading days prior
  to the Determination Date in the over-the-counter market; and

             
  (c)        in the absence of the listing of
  the Common Stock on any national securities exchange or an interdealer
  quotation system, an amount as reasonably determined in good faith by the
  Company’s Board of Directors upon a review of relevant factors and
  reflecting the unique characteristics of the Company.

             
  4.         No Stockholder Rights. 
  This Warrant shall not entitle its holder to any of the rights of a
  stockholder of the Company until the holder has exercised this Warrant in
  accordance with Section 6 hereof.

             
  5.         Reservation of Stock. 
  The Company covenants that during the period this Warrant is exercisable the
  Company will use its best efforts to reserve from its authorized and unissued
  shares of Common Stock a sufficient number of shares to provide for the
  issuance of Warrant shall constitute full authority to its officers who are
  charged with the duty of executing stock certificates to execute and issue the
  necessary certificates for Warrant Shares upon the exercise of this Warrant.

             
  6.         Exercise of Warrant. 
  The Warrant shall be exercisable by (i) delivery to the Company of the form of
  notice of exercise attached hereto as Exhibit A duly completed and
  signed by the Holder or by the duly appointed legal representative or duly
  authorized attorney thereof, and (ii) within five business days thereafter,
  depositing with the Company the certificate

  3

  

  
     
  

  evidencing the Warrant and paying
  the aggregate Warrant Price for the number of shares of Common Stock in
  respect of which the Warrant is being exercised; provided, that the Warrant
  Price must in any event be paid and the certificate representing the Warrant
  deposited with the Company prior to the close of business on the fifth
  business day following delivery of such notice.  Upon each partial
  exercise of the Warrant, a new Warrant evidencing the balance of the shares of
  Common Stock issuable hereunder will be issued to the Holder, as soon as
  reasonably practicable, on the same terms as the Warrant partially exercised.

             
  7.         Certificate of
  Adjustment.  Whenever the Warrant Price or number or type of
  securities issuable upon exercise of this Warrant is adjusted, as herein
  provided, the Company shall promptly deliver to the record holder of this
  Warrant a certificate of an officer of the Company setting forth the nature of
  such adjustment and a brief statement of the facts requiring such adjustment.

             
  8.         Notice of Proposed
  Transfers.  This Warrant is transferable by the Holder hereof subject
  to compliance with this Section 8.  Prior to any proposed transfer of
  this Warrant or the Warrant Shares received pursuant to the exercise of this
  Warrant (the “Securities”), unless there is in effect a registration
  statement under the Securities Act of 1933, as amended (the “Securities Act”),
  covering the proposed transfer, the Holder thereof shall (i) provide to the
  Company a letter of representation, addressed from the proposed transferee to
  the Company, acceptable to the Company and its counsel, and (ii) give written
  notice to the Company of such Holder’s intention to effect such
  transfer.  Each such notice shall describe the manner and circumstances
  of the proposed transfer in sufficient detail, and shall, if the Company so
  requests, be accompanied (except in transactions in compliance with Rule 144)
  by either (i) an unqualified written opinion of legal counsel who shall be
  reasonably satisfactory to the Company addressed to the Company and reasonably
  satisfactory in form and substance to the Company’s counsel, to the effect
  that the proposed transfer of the Securities may be effected without
  registration under the Securities Act, or (ii) a “no action” letter from
  the Securities and Exchange Commission (the “Commission”) to the effect
  that the transfer of such Securities without registration will not result in a
  recommendation by the staff of the Commission that enforcement action be taken
  with respect thereto, whereupon the Holder of the Securities shall be entitled
  to transfer the Securities in accordance with the terms of the notice
  delivered by the Holder to the Company; provided, however, no
  such registration statement or opinion of counsel shall be necessary for a
  transfer by a Holder to any affiliate of such Holder or a transfer by a Holder
  which is a partnership to a partner of such partnership or a retired partner
  of such partnership who retires after the date hereof, or to the estate of any
  such partner or retired partner or the transfer by gift, will or intestate
  succession of any partner to his spouse or lineal descendants or ancestors, if
  the transferee agrees in writing to be subject to the terms hereof to the same
  extent as if such transferee were the original Holder hereunder.  In
  connection with any transfer of this Warrant, the Holder shall provide the
  Company with funds sufficient to pay any applicable transfer taxes or evidence
  that any such transfer taxes have been paid or that no such transfer taxes are
  due.  Each certificate evidencing the Securities transferred as above
  provided shall bear the appropriate restrictive legend set forth above, except
  that such certificate shall not bear such restrictive legend if in the opinion
  of counsel for the Company such legend is not required in order to establish
  compliance with any provisions of the Securities Act.

  9.         Replacement of Warrants. 
  Upon receipt by the Company of evidence reasonably satisfactory to the Company
  of the loss, theft, destruction or mutilation of the Warrant, and in the case
  of any such loss, theft or destruction of the Warrant, on delivery of an
  indemnity agreement or security reasonably satisfactory in form and amount to
  the Company, and reimbursement to the Company of all reasonable expenses
  incidental thereto, and upon surrender and cancellation of the Warrant if
  mutilated, the Company will execute and deliver, in lieu thereof, a new
  Warrant of like tenor.

             
  10.       Dividends and Distributions. 
  For so long as any part of this Warrant remains outstanding and unexercised,
  the Company will, upon the declaration of a cash dividend upon its Common
  Stock or other distribution to the holders of its Common Stock and at least
  ten (10) days prior to the record date, notify the Holder hereof of such
  declaration, which notice will contain, at a minimum, the following
  information:  (i) the date of the declaration of the dividend or
  distribution, (ii) the amount of such dividend or distribution (iii) the
  record date of such dividend or distribution, and (iv) the payment date or
  distribution date of such dividend or distribution.  The Holder shall,
  upon the exercise hereof, be entitled to receive, in addition to the number of
  shares of Common Stock receivable thereupon, and without payment of any
  additional consideration therefor the amount of such other or additional
  securities or other property (other than cash) of the Company which such
  Holder would hold on the date of such exercise had it been the holder of
  record of such Common Stock on the date thereof and had thereafter, during the
  period from the date thereof to and including the date of such exercise,
  retained such shares and/or all other additional securities or other property
  receivable by it as aforesaid during such period, giving effect to all
  adjustments pursuant to Section 2.

             
  11.       Miscellaneous.  This
  Warrant shall be governed by the laws of the State of North Carolina. 
  The headings in this Warrant are for purposes of convenience of reference
  only, and shall not be deemed to constitute a part hereof.  The
  invalidity or unenforceability of any provision hereof shall in no way affect
  the validity or enforceability of any other provisions.  All notices and
  other communications from the Company to the holder of this Warrant shall be
  delivered personally or mailed by first class mail, postage prepaid, to the
  address furnished to the Company in writing by the last holder of this Warrant
  who shall have furnished an address to the Company in writing, and if mailed
  shall be deemed given three (3) days after deposit in the U.S. Mail.

             
  12.       Taxes.  The Company shall
  pay all issue taxes and other governmental charges (but not including any
  income taxes of a Holder) that may be imposed in respect of the issuance or
  delivery of the Warrant Shares or any portion thereof, unless any such tax or
  charge is imposed by law upon the Holder, in which case such tax or charge
  shall be paid by the Holder.  The Company shall not be required, however,
  to pay any tax or other charge imposed in connection with any transfer
  involved in the issuance of any certificate for shares of Common Stock in any
  name other than that of the Holder, and in such case the Company shall not be
  required to issue or deliver any stock certificate until such tax or other
  charge has been paid or if it has been established to the satisfaction of the
  Company that no such tax or other charge is due.

  5

  

  
     
  

             
  13.       Amendment.  Any tem of
  this Warrant may be amended with the written consent of the Company and the
  Holder.  Any amendment effected in accordance with this Section 13 shall
  be binding upon the Holder of this Warrant, each future holder of such
  Warrant, and the Company.

             
  14.       Remedies.  In the event of
  any default or threatened default by the Company in the performance of or
  observance with any of the terms of this Warrant, it is agreed that remedies
  at law are not and will not be adequate for the Holder and that such terms may
  be specifically enforced by a decree for the specific performance of any
  agreement contained herein or by an injunction against a violation of any of
  the terms hereof or otherwise.
