                     15% SUBORDINATED CONVERTIBLE DEBENTURE
                              DUE OCTOBER 25, 2008

            THIS DEBENTURE is one of a series of duly  authorized and issued 15%
Subordinated  Convertible  Debentures of Galaxy Energy  Corporation,  a Colorado
corporation,  having a principal place of business at 1331 - 17th Street,  Suite
1050, Denver, Colorado 80202 (the "COMPANY"), designated as its 15% Subordinated
Convertible Debenture, due October 25, 2008 (the "DEBENTURES").

         FOR VALUE RECEIVED,  the Company promises to pay to ________________ or
its registered  assigns (the "HOLDER"),  the principal sum of $__________ on the
Maturity  Date (as  defined  herein),  and to pay  interest to the Holder on the
aggregate unconverted and then outstanding principal amount of this Debenture at
the rate of 15% per annum, payable on each


Debenture - page 1



Conversion  Date (as to that principal  amount then being  converted) and on the
Maturity  Date (except  that,  if any such date is not a Business Day, then such
payment shall be due on the next  succeeding  Business Day), in cash, so long as
such  payment  shall  not  violate  the  terms  of any  provisions  of the  debt
instruments  and  agreements  with the  holders of the  Company's  Senior  Debt.
Specifically,  if any part of this  Debenture  shall be  converted  prior to the
Maturity  Date no interest on this  Debenture  shall be paid until the  Maturity
Date,  which shall be  automatically  extended to the earliest  date on which no
Senior Debt is outstanding.

         In the event that any portion of this  Debenture is paid after the date
that is 30  months  from the  Original  Issue  Date,  the  Company  shall pay an
additional amount to the Holder equal to the product of (a) the principal amount
of the Debenture  being  retired  multiplied by (b) the sum of 25% plus .75% for
each  month (or part  thereof)  in excess of 30 months  that the  Debenture  has
remained outstanding.

         Interest  shall be  calculated on the basis of a 365-day year and shall
accrue daily  commencing on the Original Issue Date until payment in full of the
principal sum,  together with all accrued and unpaid  interest and other amounts
which may become due  hereunder,  has been made.  Interest shall cease to accrue
with respect to any  principal  amount  converted,  provided that the Company in
fact delivers the Underlying  Shares within the time period  required by Section
4(b)(i).  Interest  hereunder  will be paid to the  Person  in whose  name  this
Debenture is registered on the records of the Company regarding registration and
transfers of Debentures (the "DEBENTURE REGISTER").

         This Debenture is subject to the following additional provisions:

         SECTION  1.  This  Debenture  is  exchangeable  for an equal  aggregate
principal  amount  of  Debentures  of  different  authorized  denominations,  as
requested by the Holder  surrendering  the same. No service  charge will be made
for such registration of transfer or exchange.

         SECTION 2. This Debenture has been issued subject to certain investment
representations  of the original Holder set forth in the Purchase  Agreement and
may be transferred or exchanged only in compliance  with the Purchase  Agreement
and applicable  federal and state securities laws and regulations.  Prior to due
presentment to the Company for transfer of this  Debenture,  the Company and any
agent of the Company may treat the Person in whose name this  Debenture  is duly
registered  on the  Debenture  Register  as the owner  hereof for the purpose of
receiving payment as herein provided and for all other purposes,  whether or not
this  Debenture is overdue,  and neither the Company nor any such agent shall be
affected by notice to the contrary.

         the  following  events  (whatever  the reason  and  whether it shall be

         regulation of any administrative or governmental body):

                  thereof  suffers any  appointment of any custodian or the like

                  Company or any subsidiary  thereof makes a general  assignment

                  creditors with a view to arranging a  composition,  adjustment
                  or   restructuring  of  its  debts;  or  the  Company  or  any
                  subsidiary  thereof  shall  by  any  act  or  failure  to  act

                           (iv)  the  Company   shall  default  in  any  of  its
                  obligations under any other Debenture or any mortgage,  credit
                  agreement or other facility,  indenture  agreement,  factoring

Debenture - page 3


                  in  such  indebtedness  becoming  or  being  declared  due and
                  payable prior to the date on which it would  otherwise  become
                  due and payable; or

                           (v) an Event (as defined in the  Purchase  Agreement)
                  shall not have been  cured to the  satisfaction  of the Holder
                  prior to the expiration of thirty days from the Event Date (as
                  defined in the Purchase Agreement).

                  (b) If any Event of  Default  occurs  and is  continuing,  all
         amounts due under this  Debenture,  together  with  interest  and other
         amounts owing in respect  thereof,  to the date of  acceleration  shall
         become at the Holder's  election,  immediately due and payable in cash.
         Interest shall accrue on the amounts due from the day after such amount
         is due  (being  the date of an Event of  Default),  retroactive  to the
         Original  Issue Date through the date of  prepayment in full thereof in
         an amount equal to the 25% per annum, to accrue daily from the Original
         Issue Date through and  including the date of payment.  All  Debentures
         for which the full  prepayment  price hereunder shall have been paid in
         accordance  herewith shall promptly be surrendered to or as directed by
         the Company.  The Holder need not provide and the Company hereby waives
         any presentment,  demand,  protest or other notice of any kind, and the
         Holder may  immediately  and  without  expiration  of any grace  period
         enforce any and all of its rights and remedies  hereunder and all other
         remedies  available to it under applicable law. Such declaration may be
         rescinded and annulled by Holder at any time prior to payment hereunder
         and the Holder  shall have all rights as a Debenture  holder until such
         time,  if any, as the full payment  under this Section  shall have been
         received  by it. No such  rescission  or  annulment  shall  affect  any
         subsequent Event of Default or impair any right consequent thereon.

         SECTION 4.   CONVERSION.

                  a) (i) At any time  after the  Closing  Date,  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 (subject to the limitations on conversion set forth in
                  Section 4(a)(ii) hereof), so long as such conversion shall not
                  violate the terms of any  provisions  of the debt  instruments
                  and agreements with the holders of the Company's  Senior Debt.
                  The Holder  shall  effect  conversions  by  delivering  to the
                  Company the form of Notice of  Conversion  attached  hereto as
                  ANNEX A (a "NOTICE OF  CONVERSION"),  specifying  therein  the
                  principal amount of Debentures to be converted and the date on
                  which such conversion is to be effected (a "CONVERSION DATE").
                  If no Conversion  Date is specified in a Notice of Conversion,
                  the  Conversion  Date  shall be the date that  such  Notice of
                  Conversion  is  provided  hereunder.   To  effect  conversions
                  hereunder,  the Holder  shall not be  required  to  physically
                  surrender   Debentures  to  the  Company   unless  the  entire
                  principal amount of this Debenture plus all accrued and unpaid
                  interest thereon has been so converted.  Conversions hereunder
                  shall have the effect of lowering  the  outstanding  principal
                  amount of this  Debenture in an amount equal to the applicable
                  conversion.  The Holder and the Company shall maintain records
                  showing the  principal  amount  converted and the date of such
                  conversions.  The Company  shall  deliver any objection to any
                  Notice of Conversion  within 1




Debenture - page 4


                  Business Day of receipt of such  notice.  In the event  of any
                  dispute  or  discrepancy,  the  records of the Holder shall be
                  controlling  and  determinative  in  the  absence  of manifest
                  error.  The  Holder  and  any  assignee, by acceptance of this
                  Debenture,  acknowledge  and  agree  that,  by  reason  of the
                  provisions  of  this  paragraph,  following  conversion  of  a
                  portion  of   this   Debenture,  the  unpaid  and  unconverted
                  principal amount of this Debenture may be less than the amount
                  stated on the face hereof.

                           (ii)  CONVERSION  LIMITATION.  The Company  shall not
                  effect any conversion of this Debenture,  and the Holder shall
                  not have the right to convert any  portion of this  Debenture,
                  pursuant to Section  4(a)(i) or otherwise,  to the extent that
                  after giving effect to such  conversion,  the Holder (together
                  with the Holder's affiliates),  as set forth on the applicable
                  Notice  of  Conversion,  would  beneficially  own in excess of
                  4.99% of the number of shares of the Common Stock  outstanding
                  immediately  after  giving  effect  to  such  conversion.  For
                  purposes of the  foregoing  sentence,  the number of shares of
                  Common  Stock   beneficially  owned  by  the  Holder  and  its
                  affiliates  shall include the number of shares of Common Stock
                  issuable  upon  conversion of this  Debenture  with respect to
                  which the  determination  of such sentence is being made,  but
                  shall exclude the number of shares of Common Stock which would
                  be issuable upon (A) conversion of the remaining, nonconverted
                  portion of this Debenture  beneficially owned by the Holder or
                  any of its  affiliates  and (B) exercise or  conversion of the
                  unexercised or nonconverted portion of any other securities of
                  the  Company  (including,   without   limitation,   any  other
                  Debentures  or  the  Warrants)  subject  to  a  limitation  on
                  conversion or exercise  analogous to the limitation  contained
                  herein  beneficially  owned  by  the  Holder  or  any  of  its
                  affiliates. Except as set forth in the preceding sentence, for
                  purposes of this Section 4(a)(ii),  beneficial ownership shall
                  be calculated in accordance with Section 13(d) of the Exchange
                  Act.  To the  extent  that the  limitation  contained  in this
                  section applies,  the  determination of whether this Debenture
                  is convertible (in relation to other  securities  owned by the
                  Holder)  and  of  which  a  portion  of  this   Debenture   is
                  convertible shall be in the sole discretion of such Holder. To
                  ensure  compliance with this  restriction,  the Holder will be
                  deemed to  represent  to the  Company  each time it delivers a
                  Notice of Conversion  that such Notice of  Conversion  has not
                  violated the  restrictions set forth in this paragraph and the
                  Company  shall have no  obligation  to verify or  confirm  the
                  accuracy of such  determination.  For purposes of this Section
                  4(a)(ii),  in determining the number of outstanding  shares of
                  Common Stock, the Holder may rely on the number of outstanding
                  shares of Common Stock as reflected in (x) the Company's  most
                  recent Form 10-Q or Form 10-K,  as the case may be, (y) a more
                  recent  public  announcement  by the  Company or (z) any other
                  notice by the Company or the Company's  Transfer Agent setting
                  forth the number of shares of Common Stock  outstanding.  Upon
                  the written or oral request of the Holder,  the Company  shall
                  within two Trading Days  confirm  orally and in writing to the
                  Holder the number of shares of Common Stock then  outstanding.
                  In any case, the number of outstanding  shares of Common Stock
                  shall be determined  after giving effect to the  conversion or
                  exercise  of  securities  of  the  Company,   including   this



Debenture - page 5


                  Debenture,  by the Holder or its affiliates  since the date as
                  of which such number of outstanding shares of Common Stock was
                  reported.  The  provisions  of this  Section  4(a)(ii)  may be
                  waived by the Holder upon, at the election of the Holder,  not
                  less  than 61  days'  prior  notice  to the  Company,  and the
                  provisions of this Section  4(a)(iiii) shall continue to apply
                  until such 61st day (or such later date,  as determined by the
                  Holder, as may be specified in such notice of waiver).

                                    In  addition,  the Company  shall not effect
                  any  conversion  of this  Debenture,  and the Holder shall not
                  have the  right to  convert  any  portion  of this  Debenture,
                  pursuant to Section  4(a)(i) or otherwise,  to the extent that
                  after giving effect to such  conversion of this  Debenture and
                  any other Debentures issued under the Purchase Agreement,  and
                  the exercise of any of the Warrants  issued under the Purchase
                  Agreement,  the Company  will have  issued in the  aggregate a
                  number of shares of its  Common  Stock  that is 20% or more of
                  the number of shares of the Common Stock.

                           (iii)  UNDERLYING  SHARES ISSUABLE UPON CONVERSION OF
                  PRINCIPAL  AMOUNT.  The  number  of  shares  of  Common  Stock
                  issuable upon a conversion shall be determined by the quotient
                  obtained by dividing (x) the outstanding  principal  amount of
                  this Debenture to be converted by (y) the Set Price.

                  (b) (i) Not later than five Trading Days after any  Conversion
                  Date,  the Company will deliver to the Holder a certificate or
                  certificates representing the Underlying Shares which shall be
                  free of restrictive  legends and trading  restrictions  (other
                  than those  required by the Purchase  Agreement)  representing
                  the number of shares of Common Stock being  acquired  upon the
                  conversion of Debentures  (including,  if so timely elected by
                  the Company,  shares of Common Stock  representing the payment
                  of  accrued  interest)  and (B) a bank  check in the amount of
                  accrued and unpaid interest (if the Company is required to pay
                  accrued interest in cash). The Company shall, if available and
                  if allowed  under  applicable  securities  laws,  use its best
                  efforts to deliver any certificate or certificates required to
                  be delivered by the Company under this Section  electronically
                  through   the   Depository   Trust   Corporation   or  another
                  established clearing corporation performing similar functions.
                  If in the case of any Notice of Conversion such certificate or
                  certificates  are  not  delivered  to or as  directed  by  the
                  applicable  Holder by the fifth Trading Day after a Conversion
                  Date,  the Holder  shall be entitled by written  notice to the
                  Company  at  any  time  on  or  before  its  receipt  of  such
                  certificate  or  certificates  thereafter,   to  rescind  such
                  conversion,  in which  event  the  Company  shall  immediately
                  return the  certificates  representing the principal amount of
                  Debentures tendered for conversion.

                           (ii) If the  Company  fails for any reason to deliver
                  to the Holder such  certificate  or  certificates  pursuant to
                  Section  4(b)(i) by the fifth Trading Day after the Conversion
                  Date,  the  Company  shall  pay to such  Holder,  in cash,  as
                  liquidated  damages  and not as a penalty,  for each $5,000 of
                  principal  amount  being   converted,   $50  per  Trading  Day
                  (increasing to $100 per Trading Day after 3


Debenture - page 6


                  Trading Days after such damages begin to accrue and increasing
                  to $200 per Trading  Day 6 Trading  Days after such after such
                  damages begin to accrue) for each Trading Day after such fifth
                  Trading  Day  until  such  certificates  are  delivered.   The
                  Company's  obligations  to issue and  deliver  the  Underlying
                  Shares upon  conversion of this  Debenture in accordance  with
                  the terms hereof are absolute and unconditional,  irrespective
                  of any action or  inaction  by the Holder to enforce the same,
                  any waiver or consent  with respect to any  provision  hereof,
                  the recovery of any judgment  against any Person or any action
                  to enforce the same, or any setoff, counterclaim,  recoupment,
                  limitation or termination,  or any breach or alleged breach by
                  the  Holder  or any  other  Person  of any  obligation  to the
                  Company or any  violation  or alleged  violation of law by the
                  Holder  or any other  person,  and  irrespective  of any other
                  circumstance  which might  otherwise  limit such obligation of
                  the Company to the Holder in  connection  with the issuance of
                  such Underlying Shares; PROVIDED, HOWEVER, such delivery shall
                  not  operate as a waiver by the Company of any such action the
                  Company may have against the Holder.  In the event a Holder of
                  this  Debenture  shall  elect  to  convert  any  or all of the
                  outstanding  principal  amount  hereof,  the  Company  may not
                  refuse  conversion  based on any claim  that the Holder or any
                  one  associated  or  affiliated  with the  Holder  of has been
                  engaged in any  violation  of law,  agreement or for any other
                  reason,  unless,  an  injunction  from  a  court,  on  notice,
                  restraining and or enjoining conversion of all or part of this
                  Debenture  shall have been sought and obtained and the Company
                  posts a  surety  bond for the  benefit  of the  Holder  in the
                  amount  of  150% of the  principal  amount  of this  Debenture
                  outstanding,  which is subject to the  injunction,  which bond
                  shall   remain   in   effect   until   the    completion    of
                  arbitration/litigation  of the  dispute  and the  proceeds  of
                  which shall be payable to such Holder to the extent it obtains
                  judgment. In the absence of an injunction precluding the same,
                  the Company shall issue  Conversion  Shares or, if applicable,
                  cash, upon a properly noticed conversion. Nothing herein shall
                  limit a Holder's  right to pursue actual damages or declare an
                  Event  of  Default  pursuant  to  Section  3  herein  for  the
                  Company's  failure to  deliver  Conversion  Shares  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. The exercise of any such
                  rights  shall not prohibit the Holders from seeking to enforce
                  damages   pursuant  to  any  other  Section  hereof  or  under
                  applicable law.

                           (iii) In addition to any other  rights  available  to
                  the Holder,  if the Company fails for any reason to deliver to
                  the  Holder  such  certificate  or  certificates  pursuant  to
                  Section  4(b)(i) by the fifth Trading Day after the Conversion
                  Date,  and if after  such  fifth  Trading  Day the  Holder  is
                  required by its brokerage  firm to purchase (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  Company  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



Debenture - page 7


                  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
                  actual sale price of the Common  Stock at the time of the sale
                  (including brokerage commissions,  if any) giving rise to such
                  purchase  obligation  and  (B) at the  option  of the  Holder,
                  either  reissue  Debentures  in 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 Company timely  complied with its delivery
                  requirements under Section 4(b)(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 actual sale
                  price  of the  Underlying  Shares  at  the  time  of the  sale
                  (including brokerage commissions,  if any) giving rise to such
                  purchase obligation was a total of $10,000 under clause (A) 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.  Notwithstanding anything
                  contained  herein to the  contrary,  if a Holder  requires the
                  Company to make payment in respect of a Buy-In for the failure
                  to  timely  deliver  certificates  hereunder  and the  Company
                  timely pays in full such  payment,  the  Company  shall not be
                  required to pay such Holder  liquidated  damages under Section
                  4(b)(ii)  in respect  of the  certificates  resulting  in such
                  Buy-In.

                  (c) (i) The conversion  price in effect on any Conversion Date
                  shall be  equal  to  $1.56 (subject  to adjustment herein)(the
                  "SET PRICE").

                           (ii) If the Company, at any time while the Debentures
                  are  outstanding:  (A) shall 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  (which,  for  avoidance of
                  doubt,  shall not include any shares of Common Stock issued by
                  the Company pursuant to this Debenture,  including as interest
                  thereon),  (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  Company,  then the Set  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  at  any  time  while  the  Debentures  are
                  outstanding and during the period commencing from the Original
                  Issue Date of this  Debenture and ending upon the later of (A)
                  24 months from the Original  Issue Date or (B) the  completion

                  of new  financing  of at least  $25,000,000  at a stock  price
                  greater  than  200%  of  the  Set  Price  (the  "FULL  RATCHET
                  ADJUSTMENT  PERIOD"),  the Company  shall issue or sell, or in
                  accordance  with  Section  4(c)(iv)  hereof  is deemed to have
                  issued or sold, any shares of Common Stock by means of Capital
                  Shares  Equivalents  (as defined in the  Purchase  Agreement),
                  except  for   Excepted   Issuances   (as  defined  in  Section
                  4(c)(iv)(E) hereof), for an effective  consideration per share
                  of less than the then Set Price or for no consideration  (such
                  lower  price,  the  "BASE  SHARE  PRICE"  and  such  issuances
                  collectively,  a  "DILUTIVE  ISSUANCE"),  then,  the Set Price
                  shall  be  reduced  to  equal  the  Base  Share  Price.   Such
                  adjustment  shall be made whenever such shares of Common Stock
                  or Capital Shares  Equivalent are issued. If at any time while
                  the   Debentures  are   outstanding   and  during  the  period
                  commencing  after  the  Full  Ratchet  Adjustment  Period  the
                  Company  shall  issue  or sell,  or in  accordance  with  this
                  Section  4(c)(iv)  hereof is deemed to have  issued or sold by
                  shares of Common Stock by means of Capital Shares Equivalents,
                  except  for   Excepted   Issuances   (as  defined  in  Section
                  4(c)(iv)(E)  hereof),  for a consideration  less than the then
                  Set  Price  or  for no  consideration,  then,  and  thereafter
                  successively  upon each  such  issue,  the Set Price  shall be
                  reduced as follows:  (X) the number of shares of Common  Stock
                  outstanding   immediately   prior  to  such  issue   shall  be
                  multiplied  by the Set  Price  in  effect  at the time of such
                  issue  and  the  product  shall  be  added  to  the  aggregate
                  consideration, if any, received by the Company upon such issue
                  of  additional  shares  of  Common  Stock;  and (Y) the sum so
                  obtained  shall be  divided  by the number of shares of Common
                  Stock outstanding  immediately after such issue. The resulting
                  quotient  shall be the adjusted Set Price.  The Company  shall
                  notify the Holder in writing,  no later than the  business day
                  following the issuance of any Capital Shares or Capital Shares
                  Equivalent  subject to this  section,  indicating  therein the
                  adjusted Set Price.

                           (iv) For  purposes of  determining  the  adjusted Set
                  Price under Section  4(c)(iii)  hereof,  the following will be
                  applicable:

                                    (A)  ISSUANCE OF RIGHTS OR  OPTIONS.  If the
                           Company in any manner  issues or grants any warrants,
                           rights  or  options,   whether  or  not   immediately
                           exercisable,  to subscribe for or to purchase  Common
                           Stock or Capital Shares  Equivalent  (such  warrants,
                           rights  and  options  to  purchase  Common  Stock  or
                           Capital Shares Equivalent are hereinafter referred to
                           as "OPTIONS")  and the effective  price per share for
                           which Common  Stock is issuable  upon the exercise of
                           such Options is less than the Set Price  ("BELOW BASE
                           PRICE  OPTIONS"),  then the maximum  total  number of
                           shares of Common Stock  issuable upon the exercise of
                           all such  Below  Base Price  Options  (assuming  full
                           exercise,  conversion  or exchange of Capital  Shares
                           Equivalent,  if  applicable)  will, as of the date of
                           the  issuance  or  grant  of such  Below  Base  Price
                           Options, be deemed to be outstanding and to have been

                           share and the  maximum  consideration  payable to the
                           Company upon such exercise  (assuming  full exercise,

                           Company.   For  purposes  of  the preceding sentence,
                           the  "effective  price  per  share  for which  Common
                           Stock is issuable  upon the  exercise  of  such Below

                           the total amount,  if  any, received or receivable by
                           the  Company  as  consideration  for  the issuance or
                           granting of all such Below Base Price  Options,  plus
                           the   minimum    aggregate   amount   of   additional
                           consideration,  if any,  payable to the Company  upon
                           the  exercise  of all such Below Base Price  Options,
                           plus,  in  the  case  of  Capital  Shares  Equivalent
                           issuable  upon the  exercise of such Below Base Price
                           Options,  the minimum  aggregate amount of additional
                           consideration  payable upon the exercise,  conversion
                           or exchange  thereof at the time such Capital  Shares
                           Equivalent first become  exercisable,  convertible or
                           exchangeable,  by (ii) the  maximum  total  number of
                           shares of Common Stock  issuable upon the exercise of
                           all such  Below  Base Price  Options  (assuming  full
                           conversion   of   Capital   Shares   Equivalent,   if
                           applicable).  No further  adjustment to the Set Price
                           will be made upon the actual  issuance of such Common
                           Stock or Convertible  Securities upon the exercise of
                           such Below Base Price  Options or upon the  exercise,
                           conversion or exchange of Capital  Shares  Equivalent
                           issuable  upon  exercise  of such  Below  Base  Price
                           Options.

                                    (B) ISSUANCE OF CAPITAL  SHARES  EQUIVALENT.
                           If the  Company  in any  manner  issues  or sells any
                           Capital Shares Equivalent, whether or not immediately
                           convertible (other than where the same are treated as
                           Options or are issuable  upon the exercise of Options
                           under Section  4(c)(iv)(A))  and the effective  price
                           per share for which  Common  Stock is  issuable  upon
                           such  exercise,  conversion  or exchange is less than
                           the Set  Price,  then the  maximum  total  number  of
                           shares of Common Stock  issuable  upon the  exercise,
                           conversion  or  exchange of all such  Capital  Shares
                           Equivalent  will,  as of the date of the  issuance of
                           such  Capital  Shares  Equivalent,  be  deemed  to be
                           outstanding  and to have been  issued and sold by the
                           Company  for such  price per  share  and the  maximum
                           consideration   payable  to  the  Company  upon  such
                           exercise  (assuming  full  exercise,   conversion  or
                           exchange of Capital Shares Equivalent, if applicable)
                           will be deemed to have been  received by the Company.
                           For  the  purposes  of the  preceding  sentence,  the
                           "effective  price per share for which Common Stock is
                           issuable upon such exercise,  conversion or exchange"
                           is determined  by dividing (i) the total  amount,  if
                           any,   received  or  receivable  by  the  Company  as
                           consideration  for the  issuance  or sale of all such
                           Capital Shares Equivalent, plus the minimum aggregate
                           amount of additional  consideration,  if any, payable
                           to the  Company  upon  the  exercise,  conversion  or
                           exchange  thereof  at the time  such  Capital  Shares
                           Equivalent first become  exercisable,  convertible or
                           exchangeable,  by (ii) the  maximum  total  number of
                           shares of Common Stock  issuable  upon the  exercise,
                           conversion  or  exchange of all such  Capital  Shares
                           Equivalent.  No further  adjustment  to the Set Price
                           will be made upon the actual



Debenture - page 10



                           issuance  of  such  Common   Stock   upon   exercise,
                           conversion   or  exchange  of  such  Capital   Shares
                           Equivalent.

                                    (C)  CHANGE  IN OPTION  PRICE OR  CONVERSION
                           RATE.  If there  is a  change  at any time in (i) the
                           amount of  additional  consideration  payable  to the
                           Company upon the  exercise of any  Options;  (ii) the
                           amount of additional  consideration,  if any, payable
                           to the  Company  upon  the  exercise,  conversion  or
                           exchange of any Capital Shares  Equivalent;  or (iii)
                           the rate at which any Capital  Shares  Equivalent are
                           convertible into or exchangeable for Common Stock (in
                           each  such  case,  other  than  under or by reason of
                           provisions designed to protect against dilution), the
                           Set Price in effect at the time of such  change  will
                           be  readjusted to the Set Price which would have been
                           in effect at such time had such  Options  or  Capital
                           Shares Equivalent still outstanding provided for such
                           changed    additional    consideration   or   changed
                           conversion  rate,  as the  case  may be,  at the time
                           initially granted, issued or sold.

                                    (D) CALCULATION OF  CONSIDERATION  RECEIVED.
                           If  any  Common  Stock,  Options  or  Capital  Shares
                           Equivalent are issued,  granted or sold for cash, the
                           consideration  received therefor for purposes of this
                           Debenture will be the amount  received by the Company
                           therefor, before deduction of reasonable commissions,
                           underwriting   discounts  or   allowances   or  other
                           reasonable  expenses  paid or incurred by the Company
                           in connection  with such issuance,  grant or sale. In
                           case any Common  Stock,  Options  or  Capital  Shares
                           Equivalent  are  issued  or sold for a  consideration
                           part or all of which  shall be other than  cash,  the
                           amount of the consideration  other than cash received
                           by the Company  will be the fair market value of such
                           consideration,   except   where  such   consideration
                           consists of  securities,  in which case the amount of
                           consideration  received  by the  Company  will be the
                           fair market value  (closing  bid price,  if traded on
                           any  market)  thereof as of the date of  receipt.  In
                           case any Common  Stock,  Options  or  Capital  Shares
                           Equivalent  are issued in connection  with any merger
                           or   consolidation   in  which  the  Company  is  the
                           surviving  corporation,  the amount of  consideration
                           therefor  will be deemed to be the fair market  value
                           of such portion of the net assets and business of the
                           non-surviving  corporation as is attributable to such
                           Common Stock,  Options or Capital Shares  Equivalent,
                           as the case  may be.  The  fair  market  value of any
                           consideration  other than cash or securities  will be
                           determined in good faith by an  investment  banker or
                           other  appropriate  expert  of  national   reputation
                           selected by the Company and reasonably  acceptable to
                           the holder  hereof,  with the costs of such appraisal
                           to be borne by the Company.

                                    (E) EXCEPTED ISSUANCES.  Notwithstanding the
                           foregoing,  no  adjustment  will be made  under  this
                           Section  4(c)(iii)  in respect of (1) the granting or
                           exercise  of  options  to  employees,   officers  and
                           directors of the Company pursuant to any stock option
                           plan duly  adopted by a majority of



Debenture - page 11


                           the non-employee members of the Board of Directors of
                           the Company or a majority   of  the   members   of  a
                           committee   of non-employee directors established for
                           such purpose, (2) the conversion  of  the  Debentures
                           or  any  Debentures  of  this  series or of any other
                           series or the  conversion  or  exercise  of any other
                           security  issued by the  Company in  connection  with
                           the  offer  and  sale  of  the  Company's  securities
                           pursuant   to  the  Purchase   Agreement,   (3)   the
                           amendment,  exercise,  conversion  or  redemption  of
                           any Capital  Shares Equivalent or Options  issued and
                           outstanding  on  the  Original  Issue  Date,  (4) the
                           payment of interest on any  Senior  Debt in shares of
                           the  Company's  Common  Stock,  (5) the  issuance  of
                           any  shares or  Capital  Shares  Equivalent  pursuant
                           to  the  terms  of any convertible  securities issued
                           and outstanding on the Original Issue Date,   or  (6)
                           the   issuance  of  securities  in  connection   with
                           acquisitions  or strategic  investments,  the primary
                           purpose of which is not to raise capital.

                           (v) All  calculations  under this  Section 4 shall be
                  made to the nearest cent or the nearest 1/100th of a share, as
                  the case may be. For purposes of this Section 4, the number of
                  shares of Common Stock outstanding as of a given date shall be
                  the sum of the  number of shares  of Common  Stock  (excluding
                  treasury shares, if any) outstanding.

                           (vi)  Whenever the Set Price is adjusted  pursuant to
                  Section 4(c), the Company shall promptly mail to each Holder a
                  notice  setting forth the Set Price after such  adjustment and
                  setting forth a brief  statement of the facts  requiring  such
                  adjustment.  If the Company  issues a variable rate  security,
                  despite the prohibition thereon in the Purchase Agreement, the
                  Company  shall be  deemed  to have  issued  Capital  Shares or
                  Capital Shares  Equivalents at the lowest possible  conversion
                  or exercise price at which such securities may be converted or
                  exercised.

                           (vii) If (A) the Company shall declare a dividend (or
                  any other  distribution)  on the Common Stock; (B) the Company
                  shall  declare a special  nonrecurring  cash  dividend on or a
                  redemption  of  the  Common  Stock;   (C)  the  Company  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  Company  shall  be  required  in
                  connection with any  reclassification of the Common Stock, any
                  consolidation  or merger to which the Company is a party,  any
                  sale or transfer of all or substantially  all of the assets of
                  the Company,  of any  compulsory  share  exchange  whereby the
                  Common  Stock is  converted  into  other  securities,  cash or
                  property;  (E) the Company  shall  authorize  the voluntary or
                  involuntary  dissolution,  liquidation  or  winding  up of the
                  affairs of the Company;  then, in each case, the Company shall
                  cause to be filed at each office or agency  maintained for the
                  purpose of conversion of the Debentures, and shall cause to be
                  mailed to the  Holders at their last  addresses  as they shall
                  appear  upon  the  stock  books  of the  Company,  at least 10
                  Business Days prior to the applicable record or effective



Debenture - page 12


                  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.  Holders are entitled
                  to convert  Debentures during the 20-day period commencing the
                  date  of  such  notice  to the  effective  date  of the  event
                  triggering such notice.

                           (viii)  If,  at any  time  while  this  Debenture  is
                  outstanding,   (A)  the   Company   effects   any   merger  or
                  consolidation of the Company with or into another Person,  (B)
                  any tender offer or exchange  offer (whether by the Company or
                  another  Person) is  completed  pursuant  to which  holders of
                  Common Stock are permitted to tender or exchange  their shares
                  for other  securities,  cash or  property,  or (C) the Company
                  effects  any  reclassification  of  the  Common  Stock  or any
                  compulsory  share exchange  pursuant to which the Common Stock
                  is   effectively   converted   into  or  exchanged  for  other
                  securities, cash or property (in any such case, a "FUNDAMENTAL
                  TRANSACTION"),  then upon any  subsequent  conversion  of this
                  Debenture,  the Holder  shall have the right to  receive,  for
                  each Underlying  Share that would have been issuable upon such
                  conversion absent such Fundamental Transaction,  the same kind
                  and amount of  securities,  cash or  property as it would have
                  been   entitled  to  receive  upon  the   occurrence  of  such
                  Fundamental  Transaction if it had been,  immediately prior to
                  such  Fundamental  Transaction,  the  holder  of one  share of
                  Common Stock (the "ALTERNATE CONSIDERATION").  For purposes of
                  any such conversion,  the determination of the Set Price shall
                  be   appropriately   adjusted  to  apply  to  such   Alternate
                  Consideration  based on the amount of Alternate  Consideration
                  issuable  in  respect  of one  share of  Common  Stock in such
                  Fundamental  Transaction,  and the Company shall apportion the
                  Set Price among the  Alternate  Consideration  in a reasonable
                  manner   reflecting   the  relative  value  of  any  different
                  components  of the  Alternate  Consideration.  If  holders  of
                  Common Stock are given any choice as to the  securities,  cash
                  or property to be received in a Fundamental Transaction,  then
                  the Holder shall be given the same choice as to the  Alternate
                  Consideration   it  receives  upon  any   conversion  of  this
                  Debenture  following  such  Fundamental  Transaction.  To  the
                  extent necessary to effectuate the foregoing  provisions,  any
                  successor  to  the  Company  or   surviving   entity  in  such
                  Fundamental  Transaction  shall  issue  to  the  Holder  a new
                  debenture   consistent  with  the  foregoing   provisions  and
                  evidencing  the Holder's  right to convert such debenture into
                  Alternate  Consideration.  The terms of any agreement pursuant
                  to which a Fundamental  Transaction  is effected


Debenture - page 13




                  shall include terms  requiring any such successor or surviving
                  entity to comply with the provisions of this paragraph (c) and
                  insuring  that  this   Debenture  (or  any  such   replacement
                  security)  will be  similarly  adjusted  upon  any  subsequent
                  transaction  analogous to a  Fundamental  Transaction.  If any
                  Fundamental  Transaction constitutes or results in a Change of
                  Control  Transaction,  then  at  the  request  of  the  Holder
                  delivered   before  the  90th  day  after   such   Fundamental
                  Transaction,  the Company (or any such  successor or surviving
                  entity)  will  purchase  the  Debenture  from the Holder for a
                  purchase price, payable in cash within five Trading Days after
                  such  request  (or,  if later,  on the  effective  date of the
                  Fundamental  Transaction),  equal to the 105% of the remaining
                  unconverted  principal amount of this Debenture on the date of
                  such request,  plus all accrued and unpaid  interest  thereon,
                  plus all other accrued and unpaid amounts due hereunder.

                  (d) The Company  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 the
         Debentures  and payment of interest  on the  Debenture,  each as herein
         provided,  free from preemptive  rights or any other actual  contingent
         purchase  rights of persons other than the Holders,  not less than such
         number  of  shares  of  the  Common  Stock  as  shall  (subject  to any
         additional requirements of the Company as to reservation of such shares
         set forth in the Purchase  Agreement) be issuable  (taking into account
         the adjustments  and  restrictions of Section 4(b)) upon the conversion
         of the  outstanding  principal  amount of the Debentures and payment of
         interest  hereunder.  The Company  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 is then effective  under the Securities
         Act,  registered  for public sale in  accordance  with such  Underlying
         Shares Registration Statement.

                  (e) Upon a  conversion  hereunder  the  Company  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 VWAP
         at such time. If the Company  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.

                  (f) The  issuance  of  certificates  for  shares of the Common
         Stock on conversion of the  Debentures  shall be made without charge to
         the Holders 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 Company 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  Debentures  so  converted  and the  Company
         shall not be required to issue or deliver such  certificates  unless or
         until the person or persons  requesting the issuance thereof shall have
         paid to the Company the amount of such tax or shall have established to
         the satisfaction of the Company that such tax has been paid.

The Company  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

would  prohibit  or forgive  the  Company  from paying all or any portion of the
principal of or interest on the  Debentures  as  contemplated  herein,  wherever
enacted,  now or at any time  hereafter  in  force,  or  which  may  affect  the
covenants or the performance of this  indenture,  and the Company (to the extent
it may lawfully do so) hereby  expressly waives all benefits or advantage of any
such law,  and  covenants  that it will not, by resort to any such law,  hinder,
delay or impeded the  execution of any power herein  granted to the Holder,  but
will  suffer and permit  the  execution  of every such as though no such law has
been enacted.

      SECTION 12.  Whenever any payment or other  obligation  hereunder shall be
due on a day other than a Business  Day,  such payment shall be made on the next
succeeding Business Day.
