                                                                Right to

                       STOCK PURCHASE WARRANT (D WARRANT)

         THIS  CERTIFIES  THAT,  for  value  received,   ________________   (the
"Holder") or its registered assigns, is entitled to purchase from Summus,  Inc.,
a Delaware corporation (the "Company"),  at any time or from time to time during
the period specified in Section 2 hereof,  ___________________________  (______)
fully paid and  nonassessable  shares of the Company's  common stock,  par value
$.001 per share (the "Common  Stock"),  at an exercise  price per share equal to
$.001 (the "Exercise Price"). The term "Warrant Shares," as used herein,  refers
to the shares of Common Stock purchasable hereunder.  The Warrant Shares and the
Exercise  Price are subject to adjustment  as provided in Section 4 hereof.  The
term  "Warrants"  means this Warrant and the other warrants issued to the Holder

by the Company pursuant to Article II.A.2 of that certain 6% Secured Convertible
Debenture issued by the Company to the Holder on November 18, 2005.

         This  Warrant  is  subject  to the  following  terms,  provisions,  and
conditions:

        1.   MANNER OF EXERCISE; ISSUANCE OF CERTIFICATES; PAYMENT FOR SHARES.

            (a) Subject to the provisions hereof,  this Warrant may be exercised
by the Holder,  in whole or in part, by the surrender of this Warrant,  together
with a completed  exercise  agreement in the form attached hereto (the "Exercise
Agreement"),  to the Company during normal business hours on any business day at
the Company's principal executive offices (or such other office or agency of the
Company as it may  designate by notice to the  Holder),  and upon (i) payment to
the Company in cash, by certified or official bank check or by wire transfer for
the  account  of the  Company  of the  Exercise  Price  for the  Warrant  Shares
specified  in the  Exercise  Agreement  or (ii)  on or  after  the one (1)  year
anniversary of the date of issuance of this Warrant (the "Issue  Date"),  if the
resale of the Warrant Shares by the Holder is not then registered pursuant to an
effective  registration  statement under the Securities Act of 1933, as amended,
delivery to the Company of a written notice of an election to effect a "Cashless
Exercise" (as defined in Section 10(c) below) for the Warrant  Shares  specified
in the Exercise Agreement. The Warrant Shares so purchased shall be deemed to be
issued to the Holder or such  holder's  designee,  as the  record  owner of such
shares, as of the close of business on the date on which this Warrant shall have
been surrendered,  the completed  Exercise  Agreement shall have been delivered,
and  payment  shall have been made for such  shares (or an  election to effect a
Cashless  Exercise  has  been  made) as set  forth  above.  In the  event of any
exercise  of the  rights  represented  by this  Warrant in  accordance  with and
subject to the terms and  conditions  hereof,  either (i)  certificates  for the
Warrant  Shares shall be dated the date of such  exercise  and  delivered to the
Holder hereof within a reasonable time, not exceeding two (2) trading days after
such exercise or, (ii) if the Company's  transfer  agent is a participant in the
Deposit Withdrawal Agent Commission ("DWAC") system, the Warrant Shares shall be
issued and delivered to the  Depository  Trust  Company  account on the Holder's
behalf via the DWAC system  within a  reasonable  time,  not  exceeding  two (2)
trading days after such exercise  (the date of delivery  pursuant to (i) or (ii)
above being referred to herein as the "Warrant Share  Delivery  Date"),  and the
Holder  hereof  shall be deemed for all purposes to be the holder of the Warrant
Shares  so  purchased  as of the  date of such  exercise.  The  certificates  so
delivered shall be in such  denominations  as may be requested by the Holder and
shall be  registered  in the name of the Holder.  In the event that this Warrant
shall have been exercised only in part,  then,  unless this Warrant has expired,
the Company shall, at its expense, at the time of delivery of such certificates,
deliver  to the holder a new  Warrant  representing  the  number of shares  with
respect to which this Warrant shall not then have been exercised.

            (b) In addition to any other rights available to the Holder,  if the
Company  fails  to  deliver  to  the  Holder  a  certificate   or   certificates
representing  the Warrant  Shares  pursuant to an exercise by the Warrant  Share
Delivery  Date,  and if after such day the Holder is  required  by its broker to
purchase (in an open market  transaction or otherwise) shares of Common Stock to
deliver in  satisfaction of a sale by the Holder of the Warrant Shares which the
Holder anticipated  receiving upon such exercise (a "Buy-In"),  then the Company
shall (1) pay in cash to the Holder the amount by which (x) the  Holder's  total
purchase  price  (including  brokerage  commissions,  if any) for the  shares of
Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the
number of Warrant  Shares that the Company was required to deliver to the Holder
in  connection  with the exercise at issue times (B) the price at which the sell
order  giving



                                      2
<PAGE>

rise to such  purchase  obligation  was  executed,  and (2) at the option of the
Holder,  either  reinstate the portion of the Warrant and  equivalent  number of
Warrant  Shares for which such exercise was not honored or deliver to the Holder
the number of shares of Common Stock that would have been issued had the Company
timely  complied  with its  exercise  and delivery  obligations  hereunder.  For
example,  if the Holder  purchases Common Stock having a total purchase price of
$11,000 to cover a Buy-In  with  respect to an  attempted  exercise of shares of
Common  Stock  with an  aggregate  sale  price  giving  rise  to  such  purchase
obligation of $10,000,  under clause (1) of the immediately  preceding  sentence
the Company shall be required to pay the Holder $1,000. The Holder shall provide
the Company  written  notice  indicating  the  amounts  payable to the Holder in
respect of the Buy-In, together with applicable confirmations and other evidence
reasonably requested by the Company. Nothing herein shall limit a Holder's right
to pursue any other  remedies  available  to it  hereunder,  at law or in equity
including,   without  limitation,   a  decree  of  specific  performance  and/or
injunctive  relief  with  respect to the  Company's  failure  to timely  deliver
certificates representing shares of Common Stock upon exercise of the Warrant as
required  pursuant  to the terms  hereof.  In  addition  to all other  available
remedies at law or in equity,  if the Company fails to deliver  certificates for
the  Warrant  Shares  within  three (3)  business  days  after  this  Warrant is
exercised,  then the  Company  shall pay to the  holder  in cash a penalty  (the
"Delivery  Payment") equal to 2% of the number of Warrant Shares that the holder
is entitled to multiplied by the Market Price (as hereinafter  defined) for each
day that the Company fails to deliver  certificates for the Warrant Shares.  For
example,  if the holder is  entitled  to 100,000  Warrant  Shares and the Market
Price is $2.00,  then the  Company  shall pay to the holder  $4,000 for each day
that the  Company  fails to deliver  certificates  for the Warrant  Shares.  The
Delivery  Payment  shall be paid to the  holder  by the  fifth  day of the month
following the month in which it has accrued.

            (c) Notwithstanding  anything in this Warrant to the contrary, in no
event  shall the Holder of this  Warrant  be  entitled  to  exercise a number of
Warrants (or portions  thereof) in excess of the number of Warrants (or portions
thereof)  upon  exercise  of which the sum of (i) the number of shares of Common
Stock  beneficially owned by the Holder and its affiliates (other than shares of
Common Stock  which,  but for this  proviso,  may be deemed  beneficially  owned
through  the  ownership  of the  unexercised  Warrants  and the  unexercised  or
unconverted  portion  of any  other  securities  of  the  Company  subject  to a
limitation  on  conversion  or exercise  analogous to the  limitation  contained
herein) and (ii) the number of shares of Common Stock  issuable upon exercise of
the  Warrants  (or portions  thereof)  with  respect to which the  determination
described  herein is being made,  would  result in  beneficial  ownership by the
Holder and its affiliates of more than 9.9% of the outstanding  shares of Common
Stock,  provided,  however,  that upon the Holder of this Warrant  providing the
Company with  sixty-one  (61) days notice (the "Waiver  Notice") that the Holder
would like to waive this Section 1(c) with regard to any or all shares of Common
Stock  issuable upon  exercise of this Warrant,  this Section 1(c) will be of no
force or effect with regard to all or a portion of the Warrant referenced in the
Waiver Notice;  provided,  further,  that this provision  shall be of no further
force or effect  during  the  sixty-one  (61)  days  immediately  preceding  the
expiration  of the  term  of  this  Warrant.  For  purposes  of the  immediately
preceding sentence,  beneficial ownership shall be determined in accordance with
Section  13(d)  of  the  Securities  Exchange  Act  of  1934,  as  amended,  and
Regulations 13D-G thereunder, except as otherwise provided in clause (i) hereof.
Notwithstanding  anything in this Warrant to the contrary,  the  restrictions on
exercise of this Warrant set forth in this section shall not be amended  without
(i) the written  consent of the



                                       3
<PAGE>

Holder and the Company and (ii) the approval of the holders of a majority of the
Common Stock present,  or represented by proxy, and voting at any meeting called
to vote on the amendment of such restriction.

        2. PERIOD OF EXERCISE.  This Warrant is  exercisable at any time or from
time to time on or after the Issue  Date and  before  5:00  p.m.,  New York City
time,  on the fifth  (5th)  anniversary  of the Issue Date;  provided  that such
period  shall be extended in the event that the Holder is not  permitted to sell
the Warrant Shares pursuant to the  registration  statement to be filed pursuant
to the  Registration  Right  Agreement  (as  defined in Section  7(a)  below) or
otherwise without  restriction as to the number of Warrant Shares acquired as of
a particular  date that can be sold,  in which case the exercise  period will be
extended until the Holder is able to sell the Warrant Shares either  pursuant to
the registration  statement or otherwise as specified above,  plus an additional
period of ten (10) Trading Days (the "Exercise Period").

        3.   CERTAIN AGREEMENTS OF THE COMPANY. The Company hereby covenants and
agrees as follows:

            (a) SHARES TO BE FULLY PAID. All Warrant Shares will,  upon issuance
in accordance with the terms of this Warrant, be validly issued, fully paid, and
nonassessable  and free from all taxes,  liens,  and charges with respect to the
issue thereof.

            (b) RESERVATION OF SHARES.  During the Exercise Period,  the Company
shall at all times have  authorized,  and  reserved  for the purpose of issuance
upon exercise of this Warrant,  a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant,  in accordance with Section 4.7 of the
Purchase Agreement.

            (c) LISTING.  The Company shall  promptly  secure the listing of the
shares of Common Stock  issuable upon exercise of the Warrant upon each national
securities  exchange or automated quotation system, if any, upon which shares of
Common  Stock are then  listed  (subject to  official  notice of  issuance  upon
exercise of this  Warrant)  and shall  maintain,  so long as any other shares of
Common Stock shall be so listed, such listing of all shares of Common Stock from
time to time issuable  upon the exercise of this Warrant;  and the Company shall
so list on each national  securities  exchange or automated quotation system, as
the case may be, and shall maintain such listing of, any other shares of capital
stock of the Company  issuable  upon the exercise of this Warrant if and so long
as any  shares of the same  class  shall be listed on such  national  securities
exchange or automated quotation system.

            (d) CERTAIN ACTIONS  PROHIBITED.  The Company will not, by amendment
of its charter or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action,
avoid or seek to avoid the  observance or  performance of any of the terms to be
observed  or  performed  by it  hereunder,  but will at all times in good  faith
assist in the  carrying  out of all the  provisions  of this  Warrant and in the
taking of all such action as may  reasonably  be requested by the holder of this
Warrant in order to protect the exercise privilege of the holder of this Warrant
against dilution or other  impairment,  consistent with the tenor and purpose of
this Warrant.  Without limiting the generality of the foregoing, the Company (i)
will not increase the par value of any shares of Common  Stock  receivable  upon
the exercise of this Warrant above the Exercise  Price then in effect,  and (ii)
will take all such actions



                                       4
<PAGE>

as may be  necessary  or  appropriate  in order that the Company may validly and
legally  issue  fully  paid and  nonassessable  shares of Common  Stock upon the
exercise of this Warrant.

            (e)  SUCCESSORS  AND ASSIGNS.  This Warrant will be binding upon any
entity succeeding to the Company by merger, consolidation, or acquisition of all
or substantially all the Company's assets.

        4.  ANTIDILUTION  PROVISIONS.  During the Exercise Period,  the Exercise
Price and the number of Warrant Shares shall be subject to adjustment  from time
to time as provided in this Section 4. In the event that any  adjustment  of the
Exercise Price as required herein results in a fraction of a cent, such Exercise
Price shall be rounded up to the nearest cent.

            (a)  SUBDIVISION OR  COMBINATION OF COMMON STOCK.  If the Company at
any time  subdivides  (by any stock  split,  stock  dividend,  recapitalization,
reorganization,  reclassification  or  otherwise)  the  shares of  Common  Stock
acquirable  hereunder into a greater number of shares,  then,  after the date of
record for effecting such subdivision,  the Exercise Price in effect immediately
prior to such subdivision will be proportionately reduced. If the Company at any
time  combines  (by  reverse  stock  split,  recapitalization,   reorganization,
reclassification  or otherwise) the shares of Common Stock acquirable  hereunder
into a smaller  number of shares,  then,  after the date of record for effecting
such  combination,  the  Exercise  Price  in  effect  immediately  prior to such
combination will be proportionately increased.

            (b)  ADJUSTMENT  IN NUMBER OF SHARES.  Upon each  adjustment  of the
Exercise  Price  pursuant  to the  provisions  of this  Section 4, the number of
shares of Common Stock  issuable upon exercise of this Warrant shall be adjusted
by multiplying a number equal to the Exercise Price in effect  immediately prior
to such  adjustment  by the  number  of shares of  Common  Stock  issuable  upon
exercise of this Warrant  immediately  prior to such adjustment and dividing the
product so obtained by the adjusted Exercise Price.

            (c) CONSOLIDATION, MERGER OR SALE. If, at any time when this Warrant
is  outstanding,  there shall be any merger  (other than a merger solely for the
purpose of reincorporating in another jurisdiction),  consolidation, exchange of
shares, recapitalization, reorganization, or other similar event, as a result of
which shares of Common Stock of the Company  shall be changed into the same or a
different number of shares of another class or classes of stock or securities of
the Company or another  entity,  or in case of any sale or  conveyance of all or
substantially  all of the assets of the Company other than in connection  with a
plan of  complete  liquidation  of the  Company  (each,  a  "Change  of  Control
Transaction"),  then  Holder  shall  thereafter  have the right to receive  upon
exercise  of this  Warrant  upon the basis  and upon the  terms  and  conditions
specified  herein  and in  lieu  of  the  shares  of  Common  Stock  immediately
theretofore  issuable upon such exercise such stock,  securities or assets which
Holder would have been entitled to receive in such  transaction had this Warrant
been exercised in full immediately prior to such transaction  (without regard to
any limitations on exercise contained  herein),  including any rights (including
election  rights) that Holder would have had if Holder were a stockholder at any
time prior to the consummation of the Change of Control Transaction,  and in any
such case  appropriate  provisions  shall be made with respect to the rights and
interests of Holder to the end that the provisions  hereof  (including,  without
limitation, provisions for adjustment of the Exercise Price and of the number of
shares  of  Common  Stock



                                       5
<PAGE>

issuable upon  conversion of this Warrant) shall  thereafter be  applicable,  as
nearly as may be practicable in relation to any securities or assets  thereafter
deliverable  upon the  conversion of this Warrant.  The Company shall not effect
any transaction described in this subparagraph (e) unless (i) it first gives, to
the extent  practical,  thirty (30) days' prior written notice (but in any event
at least fifteen (15) business days prior written  notice) of the record date of
the special meeting of  stockholders  to approve,  or if there is no such record
date, the consummation of, such Change of Control Transaction (during which time
Holder shall be entitled to Exercise this Warrant),  which notice shall be given
concurrently with the first public  announcement of such  transaction,  and (ii)
the  resulting  successor  or acquiring  entity (if not the Company)  and, if an
entity  different  from the  successor  or  acquiring  entity,  the entity whose
capital  stock or assets the holders of the Common Stock are entitled to receive
as a result of such Change of Control Transaction, assumes by written instrument
the  obligations  of the  Borrower  under  this  Warrant  (including  under this
subparagraph  (c)). The above  provisions  shall  similarly  apply to successive
consolidations, mergers, sales, transfers or share exchanges.

            (d)  DISTRIBUTION  OF ASSETS.  In case the Company  shall declare or
make any distribution of its assets  (including cash) to holders of Common Stock
as a partial  liquidating  dividend,  by way of return of capital or  otherwise,
then,  after the date of record for  determining  stockholders  entitled to such
distribution,  but prior to the date of distribution, the holder of this Warrant
shall be entitled  upon  exercise of this Warrant for the purchase of any or all
of the shares of Common  Stock  subject  hereto,  to receive  the amount of such
assets  which  would have been  payable to the holder had such  holder  been the
holder of such shares of Common  Stock on the record date for the  determination
of stockholders entitled to such distribution.

            (e) NOTICE OF  ADJUSTMENT.  Upon the  occurrence  of any event which
requires any adjustment of the Exercise Price,  then, and in each such case, the
Company shall give notice  thereof to the holder of this  Warrant,  which notice
shall state the Exercise Price  resulting from such  adjustment and the increase
or  decrease  in the number of  Warrant  Shares  purchasable  at such price upon
exercise,  setting forth in reasonable  detail the method of calculation and the
facts upon which such calculation is based.  Such calculation shall be certified
by the chief financial officer of the Company.

            (f) MINIMUM  ADJUSTMENT  OF EXERCISE  PRICE.  No  adjustment  of the
Exercise  Price shall be made in an amount of less than 1% of the Exercise Price
in effect at the time such adjustment is otherwise  required to be made, but any
such lesser  adjustment  shall be carried  forward and shall be made at the time
and  together  with the next  subsequent  adjustment  which,  together  with any
adjustments  so  carried  forward,  shall  amount  to not  less  than 1% of such
Exercise Price.

            (g) NO FRACTIONAL  SHARES.  No fractional shares of Common Stock are
to be issued upon the exercise of this Warrant.  If the exercise of this Warrant
would result in a fractional share of Common Stock,  such fractional share shall
be  disregarded  and the number of shares of Common Stock issuable upon exercise
of the Warrant shall be the next higher number of shares.

            (h) OTHER NOTICES. In case at any time:


                                       6
<PAGE>

                        (i) the  Company  shall  declare any  dividend  upon the
            Common  Stock  payable  in  shares of stock of any class or make any
            other distribution  (including dividends or distributions payable in
            cash out of retained earnings) to the holders of the Common Stock;

                        (ii) the Company shall offer for  subscription  pro rata
            to the holders of the Common Stock any additional shares of stock of
            any class or other rights;

                        (iii) there shall be any capital  reorganization  of the
            Company,  or  reclassification of the Common Stock, or consolidation
            or  merger  of  the  Company  with  or  into,  or  sale  of  all  or
            substantially all its assets to, another corporation or entity; or

                        (iv)  there   shall  be  a  voluntary   or   involuntary
            dissolution, liquidation or winding-up of the Company;

then,  in each such case,  the Company  shall give to the holder of this Warrant
(a) notice of the date on which the books of the Company shall close or a record
shall be taken for  determining  the holders of Common Stock entitled to receive
any such dividend,  distribution,  or subscription rights or for determining the
holders of Common Stock entitled to vote in respect of any such  reorganization,
reclassification,  consolidation,  merger,  sale,  dissolution,  liquidation  or
winding-up  and (b) in the  case of any such  reorganization,  reclassification,
consolidation,  merger, sale, dissolution,  liquidation or winding-up, notice of
the date (or,  if not then  known,  a  reasonable  approximation  thereof by the
Company) when the same shall take place. Such notice shall also specify the date
on which the holders of Common Stock shall be entitled to receive such dividend,
distribution, or subscription rights or to exchange their Common Stock for stock
or  other  securities  or  property   deliverable   upon  such   reorganization,
reclassification,  consolidation,  merger, sale,  dissolution,  liquidation,  or
winding-up,  as the case  may be.  Such  notice  shall be given at least 30 days
prior to the record date or the date on which the Company's  books are closed in
respect thereto. Failure to give any such notice or any defect therein shall not
affect the validity of the proceedings  referred to in clauses (i), (ii),  (iii)
and (iv) above.

            (i) CERTAIN EVENTS.  If any event occurs of the type contemplated by
the  adjustment  provisions of this Section 4 but not expressly  provided for by
such  provisions,  the  Company  will give  notice of such event as  provided in
Section  4(e)  hereof,  and  the  Company's  Board  of  Directors  will  make an
appropriate  adjustment in the Exercise Price and the number of shares of Common
Stock  acquirable upon exercise of this Warrant so that the rights of the Holder
shall be neither enhanced nor diminished by such event.

            (j) CERTAIN DEFINITIONS.

                        (i) "COMMON  STOCK  DEEMED  OUTSTANDING"  shall mean the
            number of shares of Common Stock actually outstanding (not including
            shares of Common  Stock held in the treasury of the  Company),  plus
            (x) pursuant to Paragraph  4(b)(i) hereof,  the maximum total number
            of shares of Common Stock issuable upon the exercise of Options,  as
            of the date of such issuance



                                       7
<PAGE>

            or grant of such  Options,  if any,  and (y)  pursuant to  Paragraph
            4(b)(ii) hereof,  the maximum total number of shares of Common Stock
            issuable upon conversion or exchange of Convertible  Securities,  as
            of the date of issuance of such Convertible Securities, if any.

                        (ii)  "MARKET  PRICE,"  as of any  date,  (i)  means the
            average of the last  reported  sale  prices for the shares of Common
            Stock  on the  OTCBB  for the  five  (5)  trading  days  immediately
            preceding such date as reported by Bloomberg Financial Markets or an
            equivalent  reliable  reporting  service mutually  acceptable to and
            hereafter  designated  by the holder of this Warrant and the Company
            ("Bloomberg"),  or (ii) if the  OTCBB is not the  principal  trading
            market  for the  shares of Common  Stock,  the  average  of the last
            reported sale prices on the principal  trading market for the Common
            Stock during the same period as reported by  Bloomberg,  or (iii) if
            market  value  cannot  be  calculated  as of such date on any of the
            foregoing  bases, the Market Price shall be the fair market value as
            reasonably determined in good faith by (a) the Board of Directors of
            the  Company  or,  at the  option of a  majority-in-interest  of the
            holders of the outstanding Warrants by (b) an independent investment
            bank  of  nationally   recognized   standing  in  the  valuation  of
            businesses  similar to the  business of the  Company.  The manner of
            determining  the Market  Price of the Common  Stock set forth in the
            foregoing  definition shall apply with respect to any other security
            in respect of which a determination  as to market value must be made
            hereunder.

                        (iii)  "COMMON  STOCK," for  purposes of this Section 4,
            includes  the  Common  Stock,  par value  $.001 per  share,  and any
            additional  class of stock of the Company having no preference as to
            dividends or distributions on liquidation,  provided that the shares
            purchasable  pursuant to this Warrant  shall  include only shares of
            Common  Stock,  par value $.001 per share,  in respect of which this
            Warrant is exercisable,  or shares resulting from any subdivision or
            combination   of  such  Common   Stock,   or  in  the  case  of  any
            reorganization, reclassification,  consolidation, merger, or sale of
            the character referred to in Section 4(e) hereof, the stock or other
            securities or property provided for in such section.

        5.   ISSUE TAX. The issuance of certificates for Warrant Shares upon the
exercise  of this  Warrant  shall be made  without  charge to the holder of this
Warrant or such shares for any issuance  tax or other costs in respect  thereof,
provided  that the  Company  shall not be  required  to pay any tax which may be
payable in respect of any transfer  involved in the issuance and delivery of any
certificate in a name other than the holder of this Warrant.

        6.   NO RIGHTS OR LIABILITIES  AS A  SHAREHOLDER. This Warrant shall not
entitle the Holder to any voting rights or other rights as a shareholder  of the
Company.  No provision of this Warrant,  in the absence of affirmative action by
the Holder to purchase  Warrant Shares,  and no mere  enumeration  herein of the
rights or  privileges  of the Holder,  shall give rise to any  liability of such
holder for the Exercise Price or as a shareholder  of the Company,  whether such
liability is asserted by the Company or by creditors of the Company.

        7.   TRANSFER, EXCHANGE, AND REPLACEMENT OF WARRANT.

representing  in the  aggregate  the right to  purchase  the number of shares of
Common  Stock which may be  purchased  hereunder,  each of such new  Warrants to
represent  the right to purchase such number of shares as shall be designated by
the Holder at the time of such surrender.

            (c)  REPLACEMENT  OF WARRANT.  Upon  receipt of evidence  reasonably
satisfactory to the Company of the loss,  theft,  destruction,  or mutilation of
this  Warrant and, in the case of any such loss,  theft,  or  destruction,  upon
delivery of an indemnity agreement reasonably satisfactory in form and amount to
the  Company,  or,  in the  case of any  such  mutilation,  upon  surrender  and
cancellation  of this  Warrant,  the Company,  at its expense,  will execute and

Warrant in connection with any transfer, exchange, or replacement as provided in
this Section 7, this  Warrant  shall be promptly  canceled by the  Company.  The

        10.  MISCELLANEOUS.

            (a)  AMENDMENTS.  This Warrant and any provision  hereof may only be
amended by an instrument in writing signed by the Company and the Holder.


                                       10
<PAGE>

            (b) DESCRIPTIVE  HEADINGS.  The descriptive  headings of the several
sections of this Warrant are inserted for purposes of reference  only, and shall
not affect the meaning or construction of any of the provisions hereof.

            (c)  CASHLESS  EXERCISE.  Notwithstanding  anything to the  contrary
contained in this Warrant, on or after the one (1) year anniversary of the Issue
Date, if the resale of the Warrant  Shares by the holder is not then  registered
pursuant to an effective  registration  statement  under the  Securities  Act of
1933, as amended, this Warrant may be exercised by presentation and surrender of
this Warrant to the Company at its  principal  executive  offices with a written
notice of the  holder's  intention  to effect a cashless  exercise,  including a
calculation  of the  number of shares  of  Common  Stock to be issued  upon such
exercise in  accordance  with the terms hereof (a "Cashless  Exercise").  In the
event of a  Cashless  Exercise,  the  Holder  shall be  entitled  to  receive  a
certificate  for the number of Warrant Shares equal to the quotient  obtained by
dividing [(A-B) (X)] by (A), where:

            (A) = the Closing Price on the Trading Day immediately preceding the
            date of such election;

            (B) = the Exercise Price of this Warrant, as adjusted; and

            (X) = the number of Warrant  Shares  issuable  upon exercise of this
            Warrant in  accordance  with the terms of this Warrant by means of a
            cash exercise rather than a cashless exercise.

            (d) REMEDIES.  The Company  acknowledges  that a breach by it of its
obligations  hereunder will cause irreparable harm to the holder of this Warrant
by vitiating  the intent and purpose of the  transactions  contemplated  hereby.
Accordingly, the Company acknowledges that the remedy at law for a breach of its
obligations  under this Warrant will be inadequate and agrees, in the event of a
breach or  threatened  breach by the Company of the  provisions of this Warrant,
that the holder of this  Warrant  shall be  entitled,  in  addition to all other
available  remedies in law or in equity,  to an  injunction  or  injunctions  to
prevent or cure any breaches of the  provisions of this Agreement and to enforce
specifically the terms and provisions of this Warrant,  without the necessity of
showing economic loss and without any bond or other security being required.
