                          Secured Convertible Debenture


                                Due May 17, 2009

         This  Secured  Convertible  Debenture  (the  "Debenture")  is issued by
QUINTEK TECHNOLOGIES INC., a California corporation (the "Obligor"),  to CORNELL
CAPITAL  PARTNERS,  LP  (the  "Holder"),  pursuant  to that  certain  Securities
Purchase Agreement (the "Securities Purchase Agreement") of even date herewith.

         FOR VALUE RECEIVED, the Obligor hereby promises to pay to the Holder or
its  successors  and assigns the principal  sum of Seven Hundred Fifty  Thousand
Dollars  ($750,000)  together with accrued but unpaid  interest on or before May
17, 2009 (the "Maturity Date") in accordance with the following terms:

         Interest.  Interest shall accrue on the outstanding  principal  balance
hereof  at an  annual  rate  equal  to ten  percent  (10%).  Interest  shall  be
calculated on the basis of a 365-day year and the actual number of days elapsed,
to the extent  permitted by applicable law.  Interest  hereunder will be paid to
the  Holder  or its  assignee  (as  defined  in  Section  5) in whose  name this
Debenture is registered on the records of the Obligor regarding registration and
transfers of Debentures (the "Debenture Register").

         Right of  Redemption.  The Obligor at its option  shall have the right,
with three (3) business days advance written notice (the  "Redemption  Notice"),
to redeem a portion or all amounts outstanding under this Debenture prior to the
Maturity Date provided that the Closing Bid Price of the of the Obligor's Common
Stock, as reported by Bloomberg,  LP, is less than the Fixed Conversion Price at
the time of the Redemption  Notice. The Obligor shall pay an amount equal to the
principal amount being redeemed plus a redemption premium ("Redemption Premium")


                                      -1-
<PAGE>

equal to twenty  percent  (20%) of the  principal  amount  being  redeemed,  and
accrued interest,  (collectively  referred to as the "Redemption  Amount").  The
Obligor  shall  deliver to the Holder the  Redemption  Amount on the third (3rd)
business day after the Redemption Notice.

                  In the event the Obligor  exercises a redemption of either all
or a portion of the outstanding  principal amounts plus accrued interest due and
outstanding under this debenture as outlined herein,  the Holder shall receive a
warrant to purchase two hundred fifty thousand (250,000) shares of the Company's
Common Stock for every One Hundred Thousand  Dollars  ($100,000)  redeemed,  pro
rata.  (the  "Warrant") The Warrant shall be exercisable at an exercise price of
$0.0662. The Warrant shall survive for five (5) years from the issuance date and
the shares of the Company's  Common Stock  issuable upon exercise of the Warrant
shall have "piggy-back" and demand registration rights.

         Notwithstanding the foregoing in the event that the Obligor has elected
to redeem a portion of the  outstanding  principal  amount and accrued  interest
under this Debenture the Holder shall be permitted to convert all or any portion
of this Debenture during such three business day period.

         Security Agreements.  This Debenture is secured by a Security Agreement
of even  date  herewith  between  the  Obligor  and  the  Holder,  and  Security
Agreements of even date herewith between QSI and Sapphire  Consulting  Services,
both wholly owned subsidiaries of the Company, and the Holder (all such security
agreements shall be referred to as the "Security Agreement").

         Consent of Holder to Sell Capital Stock or Grant Security Interests. So
long as any of the principal amount or interest on this Debenture remains unpaid
and unconverted, the Obligor shall not, without the prior consent of the Holder,
(i)  issue  or sell any  shares  of  Common  Stock or  preferred  stock  without
consideration or for  consideration per share less than the Closing Bid Price of
the Common Stock  determined  immediately  prior to its issuance,  (ii) issue or
sell any preferred  stock,  warrant,  option,  right,  contract,  call, or other
security or instrument  granting the holder  thereof the right to acquire Common
Stock without consideration or for consideration per share less than the Closing
Bid Price of the Common  Stock  determined  immediately  prior to its  issuance,
(iii) enter into any security instrument granting the holder a security interest
in any of the assets of the Obligor, or (iv) file any registration statements on
Form S-8.  Notwithstanding the foregoing the Company shall be entitled to file a
registration   statement  on  Form  S-8   registering  up  to  fifteen   million
(15,000,000) issuable under the Company's bonafide employee stock option plan.

         Rights of First Refusal.  For a period of eighteen (18) months from the
date hereof, so long as any portion of this Debenture is outstanding  (including
principal  or accrued  interest),  if the  Obligor  intends to raise  additional
capital by the  issuance  or sale of  capital  stock of the  Obligor,  including
without  limitation  shares of any class of Common Stock, any class of preferred
stock, options, warrants or any other securities convertible or exercisable into
shares of Common  Stock  (whether  the  offering is  conducted  by the  Obligor,
underwriter,  placement agent or any third party) the Obligor shall be obligated
to offer to the Holder such issuance or sale of capital  stock,  by providing in
writing the  principal  amount of capital it intends to raise and outline of the
material  terms of such capital  raise,  prior to the offering  such issuance or

<PAGE>

         Section 3.        Conversion.

         (a) Conversion at Option of Holder.

                  (i) This Debenture shall be convertible  into shares of Common
Stock at the option of the Holder, in whole or in part at any time and from time
to time, after the Original Issue Date (as defined in Section 5) (subject to the
limitations  on  conversion  set forth in Section  3(b)  hereof).  The number of
shares of Common Stock issuable upon a conversion  hereunder equals the quotient
obtained  by  dividing  (x)  the  outstanding  amount  of this  Debenture  to be
converted  by (y) the  Conversion  Price (as  defined in Section  3(c)(i)).  The
Obligor shall deliver Common Stock certificates to the Holder prior to the Fifth
(5th) Trading Day after a Conversion Date.

                  (ii)  Notwithstanding   anything  to  the  contrary  contained
herein,  if on any Conversion  Date: (1) the number of shares of Common Stock at
the time  authorized,  unissued  and  unreserved  for all  purposes,  or held as
treasury  stock,  is  insufficient  to pay principal  and interest  hereunder in
shares of Common Stock; (2) the Common Stock is not listed or quoted for trading
on the OTC or on a  Subsequent  Market;  (3) the  Obligor  has  failed to timely
satisfy its conversion; or (4) the issuance of such shares of Common Stock would
result in a violation of Section 3(b),  then,  at the option of the Holder,  the
Obligor,  in lieu of  delivering  shares of Common  Stock  pursuant  to  Section
3(a)(i),  shall  deliver,  within  three  (3)  Trading  Days of each  applicable
Conversion  Date,  an amount in cash  equal to the  product  of the  outstanding
principal  amount to be converted  plus any interest due therein  divided by the
Conversion  Price,  chosen by the Holder,  and multiplied by the highest closing
price of the stock from date of the  conversion  notice  till the date that such
cash payment is made.

         Further,  if the  Obligor  shall  not  have  delivered  any cash due in
respect of conversion of this Debenture or as payment of interest thereon by the
fifth (5th) Trading Day after the Conversion  Date, the Holder may, by notice to
the Obligor,  require the Obligor to issue  shares of Common  Stock  pursuant to
Section  3(c),  except that for such  purpose the  Conversion  Price  applicable
thereto shall be the lesser of the Conversion  Price on the Conversion  Date and
the Conversion Price on the date of such Holder demand.  Any such shares will be
subject to the provisions of this Section.

                                      -5-
<PAGE>

                  (iii) The Holder shall effect conversions by delivering to the
Obligor  a  completed  notice  in the  form  attached  hereto  as  Exhibit  A (a
"Conversion Notice").  The date on which a Conversion Notice is delivered is the
"Conversion  Date." Unless the Holder is converting the entire  principal amount
outstanding  under this  Debenture,  the Holder is not  required  to  physically
surrender  this  Debenture  to the  Obligor  in  order  to  effect  conversions.
Conversions  hereunder  shall  have  the  effect  of  lowering  the  outstanding
principal  amount of this Debenture plus all accrued and unpaid interest thereon
in an amount  equal to the  applicable  conversion.  The Holder and the  Obligor
shall maintain  records showing the principal  amount  converted and the date of
such conversions. In the event of any dispute or discrepancy, the records of the
Holder shall be controlling and determinative in the absence of manifest error.

         (b) Certain Conversion Restrictions.

                  (i) A Holder may not convert this  Debenture or receive shares
of Common Stock as payment of interest  hereunder to the extent such  conversion
or receipt of such interest  payment  would result in the Holder,  together with
any affiliate  thereof,  beneficially  owning (as determined in accordance  with
Section  13(d) of the  Exchange  Act and the rules  promulgated  thereunder)  in
excess of 4.99% of the then  issued  and  outstanding  shares  of Common  Stock,
including  shares  issuable upon conversion of, and payment of interest on, this
Debenture  held by such Holder  after  application  of this  Section.  Since the
Holder  will not be  obligated  to report to the Obligor the number of shares of
Common  Stock it may  hold at the time of a  conversion  hereunder,  unless  the
conversion  at issue would  result in the  issuance of shares of Common Stock in
excess of 4.99% of the then outstanding shares of Common Stock without regard to
any other shares which may be  beneficially  owned by the Holder or an affiliate
thereof, the Holder shall have the authority and obligation to determine whether
the restriction  contained in this Section will limit any particular  conversion
hereunder  and to the extent  that the  Holder  determines  that the  limitation
contained in this Section  applies,  the  determination  of which portion of the
principal  amount of this Debenture is convertible  shall be the  responsibility
and  obligation of the Holder.  If the Holder has delivered a Conversion  Notice
for a  principal  amount of this  Debenture  that,  without  regard to any other
shares that the Holder or its affiliates may  beneficially  own, would result in
the issuance in excess of the  permitted  amount  hereunder,  the Obligor  shall
notify the Holder of this fact and shall  honor the  conversion  for the maximum
principal amount permitted to be converted on such Conversion Date in accordance
with the periods  described in Section 3(a)(i) and, at the option of the Holder,
either  retain any  principal  amount  tendered for  conversion in excess of the
permitted  amount  hereunder  for  future  conversions  or  return  such  excess
principal amount to the Holder.  The provisions of this Section may be waived by
a Holder (but only as to itself and not to any other  Holder) upon not less than
65 days prior notice to the Obligor.  Other  Holders  shall be unaffected by any
such waiver.

         (c) Conversion Price and Adjustments to Conversion Price.

         (i) The conversion  price in effect on any Conversion Date shall be, at
the sole  option  of the  Holder,  equal  to  either  (a)  $0.0662  (the  "Fixed
Conversion  Price")  or (b)  ninety  five  percent  (95%) of the  lowest  Volume
Weighted  Average  Price of the Common Stock during the thirty (30) trading days
immediately  preceding  the  Conversion  Date as  quoted by  Bloomberg,  LP (the
"Market Conversion Price"). The Fixed Conversion Price and the Market Conversion
Price are  collectively  referred to as the  "Conversion  Price." The Conversion


                                      -6-
<PAGE>

Price  may  be  adjusted   pursuant  to  the  other  terms  of  this  Debenture.
Notwithstanding the restriction set for the in Section 2(b)(ii) the Holder shall
have the  absolute  right to convert any or all of this  Debenture  at the Fixed
Conversion Price free of such restriction.

                   (ii) If the  Obligor,  at any time  while this  Debenture  is
outstanding,  shall (a) pay a stock dividend or otherwise make a distribution or
distributions  on  shares  of its  Common  Stock or any  other  equity or equity
equivalent   securities  payable  in  shares  of  Common  Stock,  (b)  subdivide
outstanding  shares of Common Stock into a larger number of shares,  (c) combine
(including  by way of reverse  stock split)  outstanding  shares of Common Stock
into a smaller number of shares, or (d) issue by  reclassification  of shares of
the  Common  Stock any shares of capital  stock of the  Obligor,  then the Fixed
Conversion  Price shall be multiplied by a fraction of which the numerator shall
be the number of shares of Common  Stock  (excluding  treasury  shares,  if any)
outstanding  before such event and of which the denominator  shall be the number
of shares of Common Stock  outstanding  after such event.  Any  adjustment  made
pursuant to this Section  shall become  effective  immediately  after the record
date for the determination of stockholders  entitled to receive such dividend or
distribution and shall become effective  immediately after the effective date in
the case of a subdivision, combination or re-classification.

                  (iii) If the  Obligor,  at any time  while this  Debenture  is
outstanding,  shall issue  rights,  options or warrants to all holders of Common
Stock (and not to the Holder) entitling them to subscribe for or purchase shares
of Common Stock at a price per share less than the Fixed Conversion  Price, then
the Fixed  Conversion  Price shall be  multiplied  by a  fraction,  of which the
denominator  shall be the  number  of  shares  of the  Common  Stock  (excluding
treasury  shares,  if any) outstanding on the date of issuance of such rights or
warrants  (plus the number of  additional  shares of Common  Stock  offered  for
subscription  or purchase),  and of which the  numerator  shall be the number of
shares of the Common Stock (excluding  treasury  shares,  if any) outstanding on
the date of issuance of such rights or warrants, plus the number of shares which
the  aggregate  offering  price of the total  number of shares so offered  would
purchase at the Fixed Conversion  Price.  Such adjustment shall be made whenever
such rights or warrants are issued, and shall become effective immediately after
the record date for the  determination of stockholders  entitled to receive such
rights,  options or warrants.  However,  upon the  expiration of any such right,
option or warrant to purchase  shares of the Common  Stock the issuance of which
resulted  in an  adjustment  in the  Fixed  Conversion  Price  pursuant  to this
Section,  if any such right,  option or warrant  shall expire and shall not have
been  exercised,   the  Fixed  Conversion  Price  shall  immediately  upon  such
expiration  be  recomputed  and effective  immediately  upon such  expiration be
increased  to the  price  which it would  have been  (but  reflecting  any other
adjustments  in the Fixed  Conversion  Price made pursuant to the  provisions of
this Section after the issuance of such rights or warrants)  had the  adjustment
of the Fixed Conversion Price made upon the issuance of such rights,  options or
warrants  been made on the basis of offering for  subscription  or purchase only
that number of shares of the Common Stock  actually  purchased upon the exercise
of such rights, options or warrants actually exercised.

                  (iv) If the Obligor or any subsidiary  thereof, as applicable,
at any time while this  Debenture is  outstanding,  shall issue shares of Common
Stock  or  rights,  warrants,  options  or  other  securities  or debt  that are
convertible  into or  exchangeable  for shares of Common  Stock  ("Common  Stock
Equivalents") entitling any Person to acquire shares of Common Stock, at a price
per share  less than the Fixed  Conversion  Price (if the  holder of the  Common
Stock or Common  Stock  Equivalent  so  issued  shall at any  time,  whether  by


                                      -7-
<PAGE>

operation of purchase price adjustments, reset provisions,  floating conversion,
exercise or exchange prices or otherwise, or due to warrants,  options or rights
per share  which is issued in  connection  with such  issuance,  be  entitled to
receive shares of Common Stock at a price per share which is less than the Fixed
Conversion  Price,  such issuance shall be deemed to have occurred for less than
the Fixed Conversion  Price),  then, at the sole option of the Holder, the Fixed
Conversion  Price  shall be  adjusted  to mirror  the  conversion,  exchange  or
purchase price for such Common Stock or Common Stock Equivalents  (including any
reset provisions  thereof) at issue. Such adjustment shall be made whenever such
Common Stock or Common Stock  Equivalents  are issued.  The Obligor shall notify
the Holder in writing, no later than one (1) business day following the issuance
of any  Common  Stock  or  Common  Stock  Equivalent  subject  to this  Section,
indicating therein the applicable  issuance price, or of applicable reset price,
exchange price,  conversion  price and other pricing terms. No adjustment  under
this Section  shall be made as a result of issuances and exercises of options to
purchase shares of Common Stock issued for compensatory purposes pursuant to any
of the Obligor's stock option or stock purchase plans.

                  (v) If the  Obligor,  at any  time  while  this  Debenture  is
outstanding,  shall  distribute  to all holders of Common  Stock (and not to the
Holder)  evidences  of its  indebtedness  or assets or  rights  or  warrants  to
subscribe  for or  purchase  any  security,  then in each  such  case the  Fixed
Conversion Price at which this Debenture shall  thereafter be convertible  shall
be determined by multiplying the Fixed  Conversion  Price in effect  immediately
prior to the record date fixed for  determination  of  stockholders  entitled to
receive such  distribution by a fraction of which the  denominator  shall be the
Closing Bid Price determined as of the record date mentioned above, and of which
the numerator  shall be such Closing Bid Price on such record date less the then
fair market  value at such record date of the portion of such assets or evidence
of indebtedness so distributed applicable to one outstanding share of the Common
Stock as determined by the Board of Directors in good faith.  In either case the
adjustments  shall be  described  in a  statement  provided to the Holder of the
portion  of  assets  or  evidences  of   indebtedness  so  distributed  or  such
subscription  rights  applicable to one share of Common Stock.  Such  adjustment
shall be made whenever any such  distribution is made and shall become effective
immediately after the record date mentioned above.

                  (vi) In case of any  reclassification  of the Common  Stock or
any compulsory  share  exchange  pursuant to which the Common Stock is converted
into  other  securities,  cash or  property,  the  Holder  shall  have the right
thereafter to, at its option, (A) convert the then outstanding principal amount,
together  with all accrued but unpaid  interest and any other amounts then owing
hereunder  in  respect  of this  Debenture  into the  shares  of stock and other
securities, cash and property receivable upon or deemed to be held by holders of
the Common Stock  following such  reclassification  or share  exchange,  and the
Holder of this  Debenture  shall be  entitled  upon such event to  receive  such
amount of securities,  cash or property as the shares of the Common Stock of the
Obligor into which the then  outstanding  principal  amount,  together  with all
accrued  but unpaid  interest  and any other  amounts  then owing  hereunder  in
respect of this Debenture  could have been converted  immediately  prior to such
reclassification or share exchange would have been entitled,  or (B) require the
Obligor to prepay the outstanding  principal amount of this Debenture,  plus all
interest and other amounts due and payable thereon.  The entire prepayment price
shall  be paid in cash.  This  provision  shall  similarly  apply to  successive
reclassifications or share exchanges.

                  (vii)  The  Obligor  shall  at  all  times  reserve  and  keep
available out of its authorized Common Stock the full number of shares of Common
Stock issuable upon conversion of all outstanding  amounts under this Debenture;
and within three (3)  Business  Days  following  the receipt by the Obligor of a
Holder's  notice  that  such  minimum  number  of  Underlying  Shares  is not so
reserved,  the Obligor shall promptly  reserve a sufficient  number of shares of
Common Stock to comply with such requirement.

                  (viii) All calculations  under this Section 3 shall be rounded
up to the nearest $0.01 or whole share.

                  (ix)  Whenever the  Conversion  Price is adjusted  pursuant to
Section 3 hereof, the Obligor shall promptly mail to the Holder a notice setting
forth the  Conversion  Price after such  adjustment  and  setting  forth a brief
statement of the facts requiring such adjustment.

                  (x) If (A) the Obligor  shall declare a dividend (or any other
distribution)  on the Common  Stock;  (B) the  Obligor  shall  declare a special
nonrecurring  cash  dividend on or a  redemption  of the Common  Stock;  (C) the
Obligor  shall  authorize the granting to all holders of the Common Stock rights
or warrants to  subscribe  for or  purchase  any shares of capital  stock of any
class or of any  rights;  (D) the  approval of any  stockholders  of the Obligor
shall be required in connection with any  reclassification  of the Common Stock,
any  consolidation  or  merger  to which  the  Obligor  is a party,  any sale or
transfer  of all or  substantially  all of the  assets  of the  Obligor,  of any
compulsory  share  exchange  whereby the Common  Stock is  converted  into other
securities,  cash or property;  or (E) the Obligor shall authorize the voluntary
or  involuntary  dissolution,  liquidation  or winding up of the  affairs of the
Obligor;  then, in each case, the Obligor shall cause to be filed at each office
or agency maintained for the purpose of conversion of this Debenture,  and shall
cause to be mailed to the Holder at its last address as it shall appear upon the
stock books of the  Obligor,  at least  twenty (20)  calendar  days prior to the
applicable record or effective date hereinafter  specified, a notice stating (x)
the date on which a record  is to be taken  for the  purpose  of such  dividend,
distribution, redemption, rights or warrants, or if a record is not to be taken,
the date as of which the holders of the Common Stock of record to be entitled to
such  dividend,  distributions,   redemption,  rights  or  warrants  are  to  be
determined  or (y)  the  date on  which  such  reclassification,  consolidation,
merger,  sale,  transfer or share  exchange is expected to become  effective  or
close,  and the date as of which it is expected that holders of the Common Stock
of record  shall be entitled to exchange  their  shares of the Common  Stock for
securities,  cash or other  property  deliverable  upon  such  reclassification,
consolidation,  merger,  sale,  transfer or share exchange,  provided,  that the
failure to mail such  notice or any defect  therein  or in the  mailing  thereof
shall not affect the validity of the corporate  action  required to be specified
in such  notice.  The Holder is entitled to convert  this  Debenture  during the
20-day calendar period  commencing the date of such notice to the effective date
of the event triggering such notice.

                  (xi) In case of any (1) merger or consolidation of the Obligor
or any subsidiary of the Obligor with or into another Person, or (2) sale by the
Obligor or any  subsidiary of the Obligor of more than one-half of the assets of
the Obligor in one or a series of related transactions,  a Holder shall have the
right to (A) exercise any rights under Section  2(b),  (B) convert the aggregate
amount of this  Debenture  then  outstanding  into the shares of stock and other
securities, cash and property receivable upon or deemed to be held by holders of
Common Stock following such merger, consolidation or sale, and such Holder shall


                                      -9-
<PAGE>

be entitled  upon such event or series of related  events to receive such amount
of  securities,  cash and property as the shares of Common Stock into which such
aggregate   principal  amount  of  this  Debenture  could  have  been  converted
immediately  prior to such  merger,  consolidation  or  sales  would  have  been
entitled, or (C) in the case of a merger or consolidation, require the surviving
entity to issue to the Holder a convertible  Debenture  with a principal  amount
equal to the  aggregate  principal  amount of this  Debenture  then held by such
Holder,  plus all accrued and unpaid  interest and other amounts owing  thereon,
which such  newly  issued  convertible  Debenture  shall  have  terms  identical
(including with respect to conversion) to the terms of this Debenture, and shall
be entitled to all of the rights and  privileges of the Holder of this Debenture
set forth  herein and the  agreements  pursuant  to which this  Debentures  were
issued. In the case of clause (C), the conversion price applicable for the newly
issued shares of convertible preferred stock or convertible  Debentures shall be
based upon the amount of securities, cash and property that each share of Common
Stock  would  receive in such  transaction  and the  Conversion  Price in effect
immediately prior to the effectiveness or closing date for such transaction. The
terms of any such merger,  sale or consolidation  shall include such terms so as
to  continue to give the Holder the right to receive  the  securities,  cash and
property set forth in this Section upon any  conversion or redemption  following
such event. This provision shall similarly apply to successive such events.

         (d)      Other Provisions.

                  (i) The Obligor  covenants  that it will at all times  reserve
and keep  available out of its  authorized  and unissued  shares of Common Stock
solely for the purpose of issuance upon conversion of this Debenture and payment
of interest on this  Debenture,  each as herein  provided,  free from preemptive
rights or any other actual contingent  purchase rights of persons other than the
Holder,  not less than  such  number  of  shares  of the  Common  Stock as shall
(subject to any additional requirements of the Obligor as to reservation of such
shares  set forth in this  Debenture)  be  issuable  (taking  into  account  the
adjustments  and  restrictions of Sections 2(b) and 3(c)) upon the conversion of
the  outstanding  principal  amount of this  Debenture  and  payment of interest
hereunder.  The Obligor  covenants that all shares of Common Stock that shall be
so issuable shall, upon issue, be duly and validly authorized,  issued and fully
paid,  nonassessable  and, if the Underlying Shares  Registration  Statement has
been declared effective under the Securities Act,  registered for public sale in
accordance with such Underlying Shares Registration Statement.

                  (ii) Upon a  conversion  hereunder  the  Obligor  shall not be
required to issue stock  certificates  representing  fractions  of shares of the
Common Stock, but may if otherwise permitted,  make a cash payment in respect of
any final  fraction of a share  based on the Closing Bid Price at such time.  If
the Obligor  elects not, or is unable,  to make such a cash payment,  the Holder
shall be  entitled  to receive,  in lieu of the final  fraction of a share,  one
whole share of Common Stock.

                  (iii) The  issuance of  certificates  for shares of the Common
Stock on conversion of this Debenture shall be made without charge to the Holder
thereof  for any  documentary  stamp or  similar  taxes  that may be  payable in
respect of the issue or delivery of such certificate,  provided that the Obligor
shall not be  required  to pay any tax that may be  payable  in  respect  of any
transfer  involved in the  issuance and  delivery of any such  certificate  upon
conversion  in a name  other  than  that  of the  Holder  of such  Debenture  so
converted  and the  Obligor  shall  not be  required  to issue or  deliver  such


                                      -10-
<PAGE>

certificates  unless or until the  person or  persons  requesting  the  issuance
thereof  shall  have paid to the  Obligor  the  amount of such tax or shall have
established to the satisfaction of the Obligor that such tax has been paid.

                  (iv)  Nothing  herein  shall limit a Holder's  right to pursue
actual  damages or declare an Event of Default  pursuant to Section 2 herein for
the  Obligor 's failure to deliver  certificates  representing  shares of Common
Stock upon conversion  within the period  specified herein and such Holder shall
have the  right to  pursue  all  remedies  available  to it at law or in  equity
including,   without  limitation,   a  decree  of  specific  performance  and/or
injunctive relief, in each case without the need to post a bond or provide other
security.  The  exercise of any such rights  shall not  prohibit the Holder from
seeking  to  enforce  damages  pursuant  to any  other  Section  hereof or under
applicable law.

                  (v) In addition to any other  rights  available to the Holder,
if the Obligor fails to deliver to the Holder such  certificate or  certificates
pursuant to Section  3(a)(i) by the fifth (5th) Trading Day after the Conversion
Date, and if after such fifth (5th) Trading Day the Holder purchases (in an open
market  transaction or otherwise)  Common Stock to deliver in  satisfaction of a
sale by such  Holder  of the  Underlying  Shares  which the  Holder  anticipated
receiving upon such  conversion (a "Buy-In"),  then the Obligor shall (A) pay in
cash to the Holder (in addition to any  remedies  available to or elected by the
Holder) the amount by which (x) the Holder's  total  purchase  price  (including
brokerage commissions, if any) for the Common Stock so purchased exceeds (y) the
product of (1) the  aggregate  number of shares of Common Stock that such Holder
anticipated  receiving from the conversion at issue multiplied by (2) the market
price of the Common  Stock at the time of the sale giving rise to such  purchase
obligation  and (B) at the option of the Holder,  either  reissue a Debenture in
the principal amount equal to the principal  amount of the attempted  conversion
or deliver  to the  Holder the number of shares of Common  Stock that would have
been issued had the Obligor timely complied with its delivery requirements under
Section  3(a)(i).  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
conversion  of  Debentures  with  respect  to  which  the  market  price  of the
Underlying  Shares on the date of conversion was a total of $10,000 under clause
(A) of the immediately preceding sentence,  the Obligor shall be required to pay
the  Holder  $1,000.  The  Holder  shall  provide  the  Obligor  written  notice
indicating the amounts payable to the Holder in respect of the Buy-In.

         Section  4.   Notices.   Any  notices,   consents,   waivers  or  other
communications  required or permitted to be given under the terms hereof must be
in writing and will be deemed to have been  delivered:  (i) upon  receipt,  when
delivered  personally;  (ii)  upon  receipt,  when sent by  facsimile  (provided
confirmation of transmission  is  mechanically or  electronically  generated and
kept on file by the sending  party);  or (iii) one (1) trading day after deposit

addressed to the party to receive the same. The addresses and facsimile  numbers

and hereby  waives,  to the maximum  extent  permitted  by law,  any  objection,
including  any  objection  based on forum non  conveniens to the bringing of any
such proceeding in such jurisdictions.

         Section 11. If the Obligor  fails to strictly  comply with the terms of
this  Debenture,  then the Obligor shall  reimburse the Holder  promptly for all
fees, costs and expenses,  including,  without  limitation,  attorneys' fees and
expenses incurred by the Holder in any action in connection with this Debenture,
including, without limitation, those incurred: (i) during any workout, attempted
workout,  and/or in  connection  with the  rendering  of legal  advice as to the
Holder's rights, remedies and obligations, (ii) collecting any sums which become

or enforcement of any rights or remedies of the Holder.

         Section  12. Any waiver by the Holder of a breach of any  provision  of
this Debenture  shall not operate as or be construed to be a waiver of any other
breach  of such  provision  or of any  breach  of any  other  provision  of this
Debenture. The failure of the Holder to insist upon strict adherence to any term
of this Debenture on one or more  occasions  shall not be considered a waiver or
deprive that party of the right  thereafter  to insist upon strict  adherence to
that term or any other term of this Debenture. Any waiver must be in writing.

         Section 13. If any provision of this  Debenture is invalid,  illegal or
unenforceable,  the balance of this Debenture shall remain in effect, and if any
provision is inapplicable to any person or circumstance,  it shall  nevertheless
remain applicable to all other persons and  circumstances.  If it shall be found
that any interest or other amount deemed  interest due  hereunder  shall violate
applicable laws governing  usury,  the applicable rate of interest due hereunder
shall  automatically be lowered to equal the maximum permitted rate of interest.
The Obligor  covenants  (to the extent that it may lawfully do so) that it shall
not at any time insist upon,  plead, or in any manner  whatsoever  claim or take
the benefit or advantage of, any stay, extension or usury law or other law which
would  prohibit  or forgive  the  Obligor  from paying all or any portion of the
principal of or interest on this  Debenture  as  contemplated  herein,  wherever
enacted,  now or at any time  hereafter  in  force,  or  which  may  affect  the
