Date: March 3, 1998

                            FOCUS ENHANCEMENTS, INC.
                             STOCK PURCHASE WARRANT

         THIS CERTIFIES THAT, for value received, ____________________________,
or its  registered  assigns,  is entitled to purchase  from FOCUS  ENHANCEMENTS,
INC.,  a  corporation  organized  under the laws of the State of  Delaware  (the
"Company"),  at any time or from time to time  during  the period  specified  in
Section 2 hereof,  Fifteen Thousand (15,000) fully paid and nonassessable shares
of the Company's common stock, par value $.01 per share (the "Common Stock"), at
an exercise price per share (the "Exercise Price") determined in accordance with
Section 1 hereof.  The number of shares of Common  Stock  purchasable  hereunder
(the  "Warrant  Shares") and the  Exercise  Price are subject to  adjustment  as
provided in Section 5 hereof.




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

         1.  Determination of Exercise Price. The Exercise Price shall initially
equal 115% of the Market  Price (as defined in Section 5(j) hereof) in effect on
the date of initial  issuance of this  Warrant  (the "Issue  Date") and shall be
subject to adjustment as provided in Section 5 hereof.

         2. Period of Exercise.  This Warrant shall be  exercisable  at any time
and 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 (the  "Exercise
Period").

         3. Manner of Exercise;  Issuance of  Certificates;  Payment for Shares.
Subject to the provisions hereof, including, without limitation, the limitations
contained  in Section 8 hereof,  this  Warrant  may be  exercised  by the holder
hereof,  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
during the Exercise Period 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  hereof),  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) if the holder is  effectuating  a Cashless  Exercise (as defined in Section
12(c) hereof)  pursuant to Section  12(c)  hereof,  delivery to the Company of a
written  notice of an  election  to effect a Cashless  Exercise  for the Warrant
Shares  specified in the  Exercise  Agreement.  The Warrant  Shares so purchased
shall be deemed to be issued to the holder hereof 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 as
set forth above or, if such date is not a business date, on the next  succeeding
business  date.  The Warrant  Shares so  purchased,  representing  the aggregate
number of shares specified in the Exercise Agreement,  shall be delivered to the
holder hereof  within a reasonable  time,  not exceeding two (2) business  days,
after this Warrant shall have been so exercised in accordance with the foregoing
(the "Delivery Period"). If the Company's transfer agent is participating in the
Depository Trust Company ("DTC") Fast Automated Securities Transfer program, and
so long as the certificates  therefor do not bear a legend and the holder is not
obligated to return such certificate for the placement of a legend thereon,  the
Company shall cause its transfer  agent to  electronically  transmit the Warrant
Shares so purchased to the holder by crediting  the account of the holder or its
nominee with DTC through its Deposit  Withdrawal Agent  Commission  system ("DTC
Transfer").  If  the  aforementioned  conditions  to  a  DTC  Transfer  are  not
satisfied,  the  Company  shall  deliver  to the  holder  physical  certificates
representing the Warrant Shares so purchased.  Further,  the holder may instruct
the  Company to deliver to the holder  physical  certificates  representing  the
Warrant  Shares so  purchased  in lieu of  delivering  such shares by way of DTC
Transfer. Any certificates so delivered shall be in such denominations as may be
reasonably  requested by the holder  hereof,  shall be registered in the name of
such  holder or such  other  name as shall be  designated  by such  holder  and,
following the date on which the Warrant  Shares have been  registered  under the
Securities  Act or  otherwise  may be sold by the  holder  pursuant  to Rule 144
promulgated  under the Securities Act (or a successor rule),  shall not bear any
restrictive  legend.  If 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

                                        2




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.

         If, at any time, a holder of this  Warrant  submits  this  Warrant,  an
Exercise  Agreement and payment to the Company of the Exercise Price for each of
the Warrant Shares specified in the Exercise Agreement  (including pursuant to a
Cashless Exercise), and the Company fails for any reason to deliver, on or prior
to the fourth  business day following the expiration of the Delivery  Period for
such  exercise,  the  number of shares  of Common  Stock to which the  holder is
entitled upon such exercise (an "Exercise Default"),  then the Company shall pay
to the holder payments  ("Exercise Default Payments") for an Exercise Default in
an amount  equal to One Hundred  Fifty  Dollars  ($150.00)  per day for each day
after the expiration of the Delivery  Period through and until the date on which
the Company issues and delivers  certificates  for the shares of Common Stock to
which the holder is entitled upon such exercise.  The accrued  Exercise  Default
Payment for each  calendar  month shall be paid in cash or shall be  convertible
into Common Stock, at the holder's option, as follows:

                  (a) In the event  holder  elects to take such payment in cash,
cash  payment  shall be made to  holder  by the  fifth  (5th)  day of the  month
following the month in which it has accrued; and

                  (b) In the event holder  elects to take such payment in Common
Stock, the holder may convert such payment amount into Common Stock at the lower
of the Exercise  Price or the Market  Price (as defined in Section  5(j)) (as in
effect at the time of  conversion)  at any time after the fifth (5th) day of the
month following the month in which it has accrued.

         Nothing  herein shall limit the holder's right to pursue actual damages
for the Company's  failure to maintain a sufficient  number of authorized shares
of Common  Stock as required  pursuant to the terms of Section 4(b) hereof or to
otherwise  issue  shares  of Common  Stock  upon  exercise  of this  Warrant  in
accordance with the terms hereof,  and the holder shall have the right to pursue
all  remedies  available  at law or in equity  (including  a decree of  specific
performance and/or injunctive relief).

         4. 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, claims and encumbrances.

                  (b) Reservation of Shares. 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 in full of this Warrant  (without  giving effect to the  limitations on
exercise set forth in Section 8(g) hereof).

                  (c) Listing.  The Company shall promptly secure the listing of
the shares of Common  Stock  issuable  upon  exercise of this  Warrant upon each
national securities exchange or


                                        3


automated  quotation  system, if any, upon which shares of Common Stock are then
listed or become 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 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 of the Company's assets.

                  (f) Blue Sky Laws. The Company shall, on or before the date of
issuance  of  any  Warrant  Shares,  take  such  actions  as the  Company  shall
reasonably  determine are necessary to qualify the Warrant Shares for, or obtain
exemption  for the Warrant  Shares for,  sale to the holder of this Warrant upon
the exercise hereof under applicable securities or "blue sky" laws of the states
of the United States,  and shall provide evidence of any such action so taken to
the holder of this  Warrant  prior to such  date;  provided,  however,  that the
Company  shall not be  required  to qualify as a foreign  corporation  or file a
general consent to service of process in any such jurisdiction.

         5.  Antidilution  Provisions.  The  Exercise  Price  and the  number of
Warrant Shares  issuable  hereunder  shall be subject to adjustment from time to
time as provided in this Section 5.

         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
or down to the nearest cent.

                  (a)  Subdivision  or  Combination  of  Common  Stock.  If  the
Company, at any time after the Issue Date, subdivides (by any stock split, stock
dividend, recapitalization,  reorganization,  reclassification or otherwise) its
shares of Common Stock 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  after  the  Issue   Date,   combines   (by   reverse   stock   split,
recapitalization, reorganization, reclassification or otherwise) its


                                        4





shares of Common Stock 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 5, the number of
shares of Common Stock issuable upon exercise of this Warrant and for which this
Warrant is or may become  exercisable  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 or for which this  Warrant is or
may become exercisable (as applicable) 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.   In  case  of  any
consolidation  of the  Company  with,  or merger of the  Company  into any other
corporation, 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 at any time after the Issue Date, then as a condition
of such consolidation,  merger or sale or conveyance, adequate provision will be
made  whereby  the holder of this  Warrant  will have the right to  acquire  and
receive  upon  exercise  of this  Warrant in lieu of the shares of Common  Stock
immediately  theretofore  acquirable  upon the  exercise of this  Warrant,  such
shares of stock,  securities,  cash or assets as may be issued or  payable  with
respect to or in exchange for the number of shares of Common  Stock  immediately
theretofore  acquirable  and  receivable  upon exercise of this Warrant had such
consolidation,  merger or sale or conveyance not taken place.  In any such case,
the Company will make  appropriate  provision to insure that the  provisions  of
this Section 5 will  thereafter be applicable as nearly as may be in relation to
any shares of stock or securities  thereafter  deliverable  upon the exercise of
this Warrant.  The Company will not effect any consolidation,  merger or sale or
conveyance unless prior to the consummation  thereof, the successor  corporation
(if other than the Company) assumes by written  instrument the obligations under
this Warrant and the  obligations  to deliver to the holder of this Warrant such
shares of stock,  securities  or assets  as, in  accordance  with the  foregoing
provisions, the holder may be entitled to acquire.

                  (d) Distribution of Assets.  In case the Company shall declare
or make any  distribution  of its assets (or  rights to acquire  its  assets) to
holders of Common Stock as a partial liquidating  dividend,  stock repurchase by
way of return of capital or otherwise (including any dividend or distribution to
the Company's  shareholders  of cash or shares (or rights to acquire  shares) of
capital stock of a subsidiary) (a  "Distribution"),  at any time after the Issue
Date,  then 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 (or rights)  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 shareholders  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


                                        5





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,  but the Company shall pay a
cash  adjustment  in respect of any  fractional  share which would  otherwise be
issuable in an amount equal to the same  fraction of the Market Price of a share
of Common Stock on the date of such exercise.

                  (h)      Other Notices.  In case at any time:

                      (i) the Company shall declare any dividend upon the Common
Stock  payable  in shares  of stock of any class or make any other  distribution
(other than dividends or distributions  payable in cash out of retained earnings
consistent with the Company's past practices with respect to declaring dividends
and making distributions) 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 of 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  estimate  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 seventy-five
(75) 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.


                                        6





                  (i) Certain Events.  If, at any time after the Issue Date, any
event  occurs of the type  contemplated  by the  adjustment  provisions  of this
Section 5 but not expressly  provided for by such  provisions,  the Company will
give notice of such event as provided in Section 5(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) "Closing  Bid Price"  means,  as of any date,  (i) the
closing  bid price for the  shares of Common  Stock as  reported  on the  Nasdaq
SmallCap Market by Bloomberg Financial Markets or a comparable reporting service
of national reputation selected by the Company and reasonably  acceptable to the
holder hereof if Bloomberg  Financial  Markets is not then reporting closing bid
prices for the Common Stock (collectively,  "Bloomberg"),  or (ii) if the Nasdaq
SmallCap  Market is not the  principal  trading  market for the shares of Common
Stock,  the last  reported  sale price  reported by Bloomberg  on the  principal
trading market for the Common Stock, or, if there is no sale price reported, the
last bid price  reported by  Bloomberg,  or (iii) if the foregoing do not apply,
the last sale price of such security in the over-the-counter  market on the pink
sheets or bulletin  board for such security as reported by  Bloomberg,  or if no
sale price is so reported for such security, the last bid price of such security
as reported by Bloomberg,  or (iv) if the Closing Bid Price cannot be calculated
as of such date on any of the  foregoing  bases,  the  Closing  Bid Price of the
Common  Stock  on such  date  shall  be the  fair  market  value  as  reasonably
determined by an investment  banking firm selected by the Company and reasonably
acceptable  to the holder,  with the costs of the  appraisal  to be borne by the
Company. The manner of determining the Closing Bid 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.

                      (ii)  "Common  Stock,"  for  purposes  of this  Section 5,
includes  the  Common  Stock 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 Common
Stock 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 5(c) hereof,  the stock or other securities or
property provided for in such Section.

                      (iii) "Market Price" means, as of any date, the average of
the Closing Bid Prices for the Common Stock for the five (5) consecutive trading
days ending on the trading day immediately  preceding such date of determination
(subject  to  equitable  adjustment  for  any  stock  splits,  stock  dividends,
reclassifications  or similar events  occurring during such five (5) trading day
period).

         6. 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.


                                        7





         7. No Rights or Liabilities  as a  Shareholder.  This Warrant shall not
entitle the holder  hereof 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 hereof to purchase Warrant Shares,  and no mere enumeration
herein of the rights or privileges of the holder hereof,  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.

         8.       Transfer, Exchange, Redemption and Replacement of Warrant.

                  (a)  Restriction  on  Transfer.  This  Warrant  and the rights
granted  to the  holder  hereof  are  transferable,  in whole  or in part,  upon
surrender of this Warrant,  together with a properly executed  assignment in the
form  attached  hereto,  at the office or agency of the  Company  referred to in
Section 8(e) below; provided,  however, that any transfer or assignment shall be
subject to the conditions  set forth in Sections 8(f) and (g) hereof.  Until due
presentment  for  registration  of  transfer  on the books of the  Company,  the
Company may treat the  registered  holder  hereof as the owner and holder hereof
for all  purposes,  and the  Company  shall not be affected by any notice to the
contrary.


                  (b) Warrant  Exchangeable  for Different  Denominations.  This
Warrant is  exchangeable,  upon the surrender hereof by the holder hereof at the
office or agency of the  Company  referred  to in Section  8(e)  below,  for new
Warrants of like tenor of different denominations  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 hereof 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 deliver, in lieu thereof, a new Warrant of like tenor.

                  (d) Cancellation;  Payment of Expenses.  Upon the surrender of
this Warrant in  connection  with any  transfer,  exchange,  or  replacement  as
provided  in this  Section 8, this  Warrant  shall be  promptly  canceled by the
Company.  The Company shall pay all taxes (other than securities transfer taxes)
and all other  expenses  (other  than legal  expenses,  if any,  incurred by the
holder or transferees)  and charges payable in connection with the  preparation,
execution,  and  delivery  of Warrants  pursuant to this  Section 8. The Company
shall  indemnify  and  reimburse  the holder of this  Warrant  for all costs and
expenses  (including  legal fees) incurred by such holder in connection with the
enforcement of its rights hereunder.

                  (e) Warrant  Register.  The  Company  shall  maintain,  at its
principal executive offices (or such other office or agency of the Company as it
may designate by notice to the holder hereof),  a register for this Warrant,  in
which the Company  shall record the name and address of the person in whose name
this Warrant has been issued, as well as the name and address of each transferee
and each prior owner of this Warrant.

                  (f) Exercise or Transfer Without Registration. If, at the time
of the surrender of this Warrant in connection with any exercise,  transfer,  or
exchange of this  Warrant,  this Warrant (or, in the case of any  exercise,  the
Warrant Shares issuable hereunder), shall not be registered under the Securities
Act and under  applicable  state  securities  or blue sky laws,  the Company may
require, as a condition of allowing such exercise,  transfer,  or exchange,  (i)
that the holder or transferee of this  Warrant,  as the case may be,  furnish to
the  Company a written  opinion  of  counsel  (which  opinion  shall be in form,
substance and scope customary for opinions of counsel in comparable transactions
and  reasonably  acceptable  to counsel to the  Company) to the effect that such
exercise,  transfer,  or exchange  may be made  without  registration  under the
Securities Act and under  applicable state securities or blue sky laws (the cost
of which shall be borne by the Company if the Company's  counsel renders such an
opinion  and up to $250 of such  cost  shall  be  borne  by the  Company  if the
holder's  counsel is requested to render such opinion),  (ii) that the holder or
transferee  execute and deliver to the Company an investment  letter in form and
substance  acceptable  to the  Company  and  (iii)  that  the  transferee  be an
"accredited investor" as defined in Rule 501(a) promulgated under the Securities
Act;  provided  that  no such  opinion,  letter,  or  status  as an  "accredited
investor" shall be required in connection  with a transfer  pursuant to Rule 144
under the Securities Act.

                  (g)   Additional   Restrictions   on  Exercise  or   Transfer.
Notwithstanding  anything  contained  herein to the contrary,  unless the holder
hereof  delivers a waiver in  accordance  with the last sentence of this Section
8(g),  this Warrant  shall not be  exercisable  by a holder hereof to the extent
(but  only to the  extent)  that  (a) the  number  of  shares  of  Common  Stock
beneficially  owned by such  holder and its  affiliates  (other  than  shares of
Common Stock which may be deemed beneficially owned through the ownership of the
unexercised portion of this Warrant or 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 (b) the number of
shares of Common  Stock  issuable  upon  exercise  of the  Warrant  (or  portion
thereof) with respect to which the determination described herein is being made,
would result in beneficial  ownership by such holder and its  affiliates of more
than 4.99% of the  outstanding  shares of Common Stock.  To the extent the above
limitation applies, the determination of whether and to what extent this Warrant
shall be exercisable vis-a-vis other securities owned by such holder shall be in
the sole  discretion  of the holder and  submission  of this Warrant for full or
partial exercise shall be deemed to be the holder's determination of whether and
the extent to which this  Warrant is  exercisable,  in each case subject to such
aggregate  percentage  limitation.  No prior  inability  to exercise the Warrant
pursuant  to this  Section  shall  have any effect on the  applicability  of the
provisions  of this  Section  with respect to any  subsequent  determination  of
exerciseability.  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 Regulation  13D-G  thereunder,  except as
otherwise  provided in clause (a) hereof.  Except as provided in the immediately
succeeding sentence,  the restrictions contained in this Section 8(g) may not be
amended  without the consent of the holder of this  Warrant and the holders of a
majority of the Company's then  outstanding  Common Stock.  Notwithstanding  the
foregoing,  the  holder  hereof  may  waive the  restrictions  set forth in this
Section 8(g) by written  notice to the Company upon not less than sixty-one (61)
days prior notice (with such waiver  taking  effect only upon the  expiration of
such sixty-one (61) day notice period).

         9.  Registration  Rights.  The  initial  holder  of this  Warrant  (and
assignees  thereof)  shall be entitled to have the resale of the Warrant  Shares
issuable upon exercise of or otherwise pursuant


                                        9

other signatories thereto.

receipt  requested)  or  delivered  personally  or by  courier  or by  confirmed
telecopy,  and shall be effective  five days after being placed in the mail,  if
mailed,  or upon receipt or refusal of receipt,  if delivered  personally  or by

contracts  made and to be  performed  in the  State  of  Delaware.  The  Company
irrevocably consents to the jurisdiction of the United States federal courts and
state courts located in the State of Delaware in any suit or proceeding based on
or arising under this Warrant and irrevocably  agrees that all claims in respect
of such  suit or  proceeding  may be  determined  in such  courts.  The  Company
irrevocably  waives any  objection  to the laying of venue and the defense of an
inconvenient  forum to the  maintenance of such suit or proceeding.  The Company
further  agrees that service of process upon the Company  mailed by certified or
registered  mail shall be deemed in every respect  effective  service of process
upon the Company in any such suit or proceeding. Nothing herein shall affect the
holder's  right to serve  process  in any other  manner  permitted  by law.  The
Company  agrees  that a  final  non-appealable  judgment  in any  such  suit  or
proceeding  shall be conclusive  and may be enforced in other  jurisdictions  by
suit on such judgment or in any other lawful manner.



                                       10





         12.      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
hereof.

                  (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,  if the resale of the Warrant Shares by the
holder is not then registered  pursuant to an effective  registration  statement
under the  Securities  Act,  this Warrant may be exercised at any time after the
first  anniversary  of the Issue Date until the end of the Exercise  Period,  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, in lieu of paying the
Exercise Price in cash, the holder shall  surrender this Warrant for that number
of shares of Common Stock determined by multiplying the number of Warrant Shares
to which it would  otherwise be entitled by a fraction,  the  numerator of which
shall be the difference  between the then current Market Price of a share of the
Common Stock on the date of exercise and the Exercise Price, and the denominator
of which shall be the then current Market Price per share of Common Stock.

                  (d)  Business  Day.  For  purposes of this  Warrant,  the term
"business  day" means any day, other than a Saturday or Sunday or a day on which
banking  institutions  in the State of New York are  authorized  or obligated by
law, regulation or executive order to close.
