                  SENIOR SUBORDINATED SECURED CONVERTIBLE NOTE

Issuance Date:  May 26, 2005

Principal:  U.S. $2,000,000

FOR VALUE RECEIVED,  GSE Systems,  Inc., a Delaware corporation (the "Company"),
hereby  promises to pay to the order of Dolphin Direct Equity  Partners,  LP, or
its registered assigns  ("Holder"),  the amount set forth above as the Principal
(as adjusted, pursuant to the terms hereof pursuant to conversion, redemption or
otherwise, the "Principal") when due, whether upon the Maturity Date (as defined
below),  acceleration,  redemption or otherwise (in each case in accordance with
the terms hereof) and to pay interest  ("Interest") on any outstanding Principal
at a rate per annum equal to the Interest Rate (as defined below), from the date
set out above as the Issuance Date (the "Issuance  Date") until the same becomes
due and payable,  whether upon an Interest Date (as defined below), the Maturity
Date,  acceleration,  conversion,  redemption  or  otherwise  (in  each  case in
accordance  with  the  terms  hereof).  This  Convertible  Note  (including  all
Convertible  Notes  issued in exchange,  transfer or  replacement  hereof,  this
"Note")  is duly  authorized  and issued  pursuant  to the  Securities  Purchase
Agreement.  Certain  capitalized  terms are  defined in Section  26.  References
herein to the Note or the Warrant  mean all such Notes or Warrants to the extent
it,  any or all of them  are  reissued,  subdivided,  transferred,  substituted,
combined or  otherwise  restructured  in any way, and  references  to the Holder
include all holders of all outstanding such Notes.

(1) MATURITY.  On the Maturity Date, the Holder shall surrender this Note to the
Company and the Company  shall pay to the Holder an amount in cash  representing
all  outstanding  Principal,  accrued and unpaid  Interest.  The "Maturity Date"
shall be March 31,  2009,  as may be extended at the option of the Holder in the
event that, and for so long as, an Event of Default (as defined in Section 4(a))
shall have  occurred and be  continuing  or any event shall have occurred and be
continuing  which with the passage of time and the failure to cure would  result
in an Event of Default.

(2) INTEREST;  INTEREST RATE. Interest on this Note shall commence accruing at a
rate (the "Interest  Rate") equal to 8% per annum on the Issuance Date and shall
be computed on the basis of a 365-day  year and actual days elapsed and shall be
payable in arrears on the last day of each calendar  quarter and on the Maturity
Date  during  the  period  beginning  on the  Issuance  Date and  ending on, and
including,  the Maturity Date (each, an "Interest Date") with the first Interest
Date being June 30,  2005;  provided  however  that the  Interest  Rate for each
calendar  quarter  during which the  Registration  Statement  (as defined in the
Securities  Purchase  Agreement)  shall have been effective  during the entirety
thereof  shall be as  determined  above and  reduced  by the  product  of (x) 2%
multiplied by (y) the whole number quotient, regardless of remainder, of (A) the
quotient of (1) the  positive  amount by which the  average  Closing Bid for the
last ten  Trading  Days of the then most  recently  completed  calendar  quarter
exceeds the Co nversion Price (as defined below) as of such date, divided by (2)
such Conversion  Price,  divided by (B) .25. From and after the occurrence of an
Event of Default,  the Interest Rate shall be increased to  twenty-four  percent
(24%).  In the event  that such  Event of Default  is  subsequently  cured,  the
increase referred to in the preceding sentence shall cease to be effective as of
the  date of such  cure;  provided  that  the  Interest  as  calculated  at such
increased rate during the continuance of such Event of Default shall continue to
apply to the extent  relating to the days after the  occurrence of such Event of
Default through and including the date of cure of such Event of Default.

(3)  CONVERSION OF NOTE.  This Note shall be  convertible  into shares of common
stock of the  Company,  par value $.01 per share (the  "Common  Stock"),  on the
terms and conditions set forth in this Section 3.

     (a) Conversion  Right.  At any time or times on or after the Issuance Date,
until any time prior to the close of business on the  Business  Day prior to the
Maturity  Date,  the Holder  shall be  entitled  to convert  any  portion of the
outstanding  and unpaid  Conversion  Amount (as defined  below) in  multiples of
$1,000 principal amount into fully paid and nonassessable shares of Common Stock
in accordance with Section 3(c), at the Conversion Rate (as defined below).  The
Company  shall not  issue  any  fraction  of a share of  Common  Stock  upon any
conversion.  If the  issuance  would  result in the  issuance of a fraction of a
share of Common  Stock,  the  Company  shall  round such  fraction of a share of
Common Stock up to the nearest  whole  share,  or, at the option of the Company,
the  Company may pay cash to the Holder for the value of any  fractional  share,
based on the Closing Bid Price as of the applicable Conversion Date. The Company
shall pay any and all taxes that may be payable with respect to the issuance and
delivery of Common  Stock upon  conversion of any Conversion  Amount;  provided,
however,  that the  Company  shall not be  required  to pay any tax which may be
payable in respect of any  transfer  involved in the issue or delivery of shares
of Common  Stock in a name  other  than that of the  Holder and no such issue or
delivery  to a Person  other than the Holder  shall be made unless and until the
Person  requesting such issue and delivery has paid to the Company the amount of
any such tax or has established,  to the satisfaction of the Company,  that such
tax has been paid.

     (b)  Conversion  Rate.  The number of shares of Common Stock  issuable upon
conversion of any Conversion Amount pursuant to Section 3(a) shall be determined
by  dividing  (x)  such  Conversion  Amount  by (y) the  Conversion  Price  (the
"Conversion Rate").

          (i)  "Conversion  Amount"  means  the  sum of (A) the  portion  of the
     Principal to be converted, redeemed or otherwise with respect to which this
     determination  is being  made,  and (B) accrued  and unpaid  Interest  with
     respect to such Principal.

          (ii)  "Conversion  Price" means, as of any Conversion Date (as defined
     below)  or other  date of  determination,  and  subject  to  adjustment  as
     provided herein, $1.925, subject to adjustment as provided herein.

     (c) Mechanics of Conversion.

          (i) Optional Conversion.  To convert any Conversion Amount into shares
     of Common  Stock on any date (a  "Conversion  Date"),  the Holder shall (A)
     transmit by facsimile (or otherwise deliver) to the Company and the Company
     shall have received on or prior to 11:59 p.m., New York Time, on such date,
     a copy of an executed  notice of conversion in the form attached  hereto as
     Exhibit I (the  "Conversion  Notice") to the Company and (B) if required by
     Section  3(c)(iii),   surrender  this  Note  to  the  Company  as  soon  as
     practicable  on or following such date (or an  indemnification  undertaking
     with respect to this Note in the case of its loss,  theft or  destruction).
     On or before the second  Business  Day  following  the date of receipt of a
     Conversion  Notice (the "Share Delivery  Date"),  the Company shall execute
     and  deliver,  to the address as  specified  in the  Conversion  Notice,  a
     certificate,  registered in the name of the Holder or its designee, for the
     number of shares of Common Stock to which the Holder shall be entitled a nd
     bearing a legend  restricting  transfer without  compliance with applicable
     securities laws. If this Note is required to be physically  surrendered for
     conversion and the  outstanding  Principal of this Note is greater than the
     Principal  portion  of the  Conversion  Amount  being  converted,  then the
     Company shall execute and deliver,  at the Company's expense, to the Holder
     a new Note representing the outstanding Principal not converted. The Person
     or Persons  entitled to receive the shares of Common Stock  issuable upon a
     conversion  of this Note shall be treated  for all  purposes  as the record
     holder or holders of such shares of Common Stock on the Conversion Date.

          (ii) Company's Failure to Timely Convert. If the Company shall fail to
     issue a certificate  to the Holder for the number of shares of Common Stock
     to which the Holder is entitled upon conversion of any Conversion Amount on
     or prior to the date which is five Business Days after the Conversion  Date
     (a  "Conversion  Failure"),  then (A) the Company  shall pay damages to the
     Holder for each date of such Conversion  Failure in an amount equal to 1.0%
     of the  product of (I) the sum of the number of shares of Common  Stock not
     issued to the  Holder on or prior to the Share  Delivery  Date and to which
     the Holder is entitled, and (II) the Closing Sale Price of the Common Stock
     on the Share  Delivery Date and (B) the Holder,  upon written notice to the
     Company, may void its Conversion Notice with respect to, and retain or have
     returned,  as the case may be,  any  portion of this Note that has not been
     converted pursuant to such Conversion Notice;  provided that the voiding of
     a Conversion Notice shall not affect the Company's  obligations to make any
     payments  which have accrued  prior to the date of such notice  pursuant to
     this Section 3(c)(ii) or otherwise. In addition to the foregoing, if within
     three (3) Trading Days after the Company's receipt of the facsimile copy of
     a  Conversion  Notice  the  Company  shall fail to  execute  and  deliver a
     certificate for the number of shares of Common Stock to which the Holder is
     entitled upon such Holder's  conversion of any Conversion Amount, and if on
     or  after  such  Trading  Day  the  Holder  purchases  (in an  open  market
     transaction or otherwise) Common Stock to deliver in satisfaction of a sale
     by the Holder of Common Stock issuable upon such conversion that the Holder
     anticipated  receiving  from the  Company (a  "Buy-In"),  then the  Company
     shall,  within three  Business  Days after the Holder's  request and in the
     Holder's  discretion,  either (i) pay cash to the Holder in an amount equal
     to the Holder's total purchase price (including brokerage  commissions,  if
     any) for the shares of Common Stock so purchas ed (the "Buy-In Price"),  at
     which point the Company's  obligation to deliver such  certificate  (and to
     issue such  Common  Stock)  shall  terminate,  or (ii)  promptly  honor its
     obligation   to  issue  to  the  Holder  a  certificate   or   certificates
     representing  such  Common  Stock  and pay cash to the  Holder in an amount
     equal to the excess (if any) of the  Buy-In  Price over the  product of (A)
     such number of shares of Common  Stock,  times (B) the Closing Bid Price on
     the Conversion Date.

          (iii) Book-Entry.  Notwithstanding  anything to the contrary set forth
     herein,  upon conversion of any portion of this Note in accordance with the
     terms hereof, the Holder shall not be required to physically surrender this
     Note to the Company.  Following any such  conversion of any portion of this
     Note, the outstanding  Principal  represented by this Note may be less than
     the Principal stated on the face of this Note.

          (iv) Pro Rata  Conversion;  Disputes.  In the event  that the  Company
     receives  a  Conversion  Notice  from more than one holder of Notes for the
     same Conversion Date and the Company can convert some, but not all, of such
     portions of the Notes submitted for  conversion,  the Company shall convert
     from each holder of Notes  electing to have Notes  converted on such date a
     pro rata  amount  of such  holder's  portion  of its  Notes  submitted  for
     conversion  based on the principal amount of Notes submitted for conversion
     on such date by such holder relative to the aggregate  principal  amount of
     all Notes  submitted for conversion on such date. In the event of a dispute
     as to the  number  of  shares of Common  Stock  issuable  to the  Holder in
     connection  with a conversion of this Note,  the Company shall issue to the
     Holder the number of shares of Common Stock not in dispute and resolve such
     dispute in accordance with Section 19.

     (d)  Limitation  on  Conversion.  Until the 20-day  period  referred  to in
Section 4(c) of the Securities Purchase Agreement has elapsed with the result of
permitting the Company to give effect to the Conversion Share Limit  Termination
(as defined in the  Securities  Purchase  Agreement),  or the Company  otherwise
complies  with the Amex  Stockholder  Approval  Requirements  (as defined in the
Securities  Purchase  Agreement)  with  respect  to the  issuance  of this Note,
notwithstanding  any provision of this Note to the  contrary,  the Company shall
not effect any  conversion  of this Note,  and the Holder of this Note shall not
have the right to convert this Note pursuant to Section 3(a), to the extent that
giving effect to such conversion would result in the actual issuance of a number
of shares of Common Stock,  when  aggregated with the number of shares of Common
Stock actually issued or issuable upon the exercise of the Warrant, in excess of
19.99% of the number of shares of Common Stock outstanding  immediately prior to
the Subscription  Date;  provided that the calculation of such percentage at any
time shall be made  without  giving  effect to, and assuming the absence of, any
adjustment contemplated by Section 7(b) or (c) hereof.

(4) EVENT OF DEFAULT.

     (a) Each of the following events shall constitute an "Event of Default":

          (i) the  suspension  from trading or failure of the Common Stock to be
     listed on an Eligible Market for a period of five (5)  consecutive  days or

     holder of the Notes, including by way of public announcement,  at any time,

     into  shares of Common  Stock  that are  tendered  in  accordance  with the
     provisions of the Notes;

          (iii) at any time  following the tenth  consecutive  Business Day that

     receive  upon a  conversion  of the full  Conversion  Amount  of this  Note
     (without  regard to any limitations on conversion set forth in Section 3(d)
     or otherwise);

          (iv)  the  Company's  failure  to pay  to the  Holder  any  amount  of

     pay Interest when and as due,  that such failure  continues for a period of

     amount) in respect of any  Material  Indebtedness,  which  payment  failure
     individually or when aggregated with all other such payment failures within
     six months thereof shall be in the amount of at least $25,000,  when and as
     the  same  shall  become  due  and  payable  (after  giving  effect  to the
     expiration of any grace or cure period set forth  therein) or (B) any event
     or condition occurs that results in any Material  Indebtedness becoming due
     prior to its  scheduled  maturity or that enables or permits  (after giving
     effect to the expiration of any grace or cure period set forth therein) the
     holder or holders of any such Material Indebtedness or any trustee or agent
     on its or their behalf to cause any such  Material  Indebtedness  to become
     due, or to require the  prepayment,  repurchase,  redemption  or defeasance

          (ix) the Company  breaches  in any  material  respect any  covenant or
     other term or condition of any Transaction  Document (other than covenants,
     terms or conditions,  the breach of which constitutes an "Event of Default"

     months of the date thereof.

     (b) Redemption Right. Promptly after the occurrence of an Event of Default,

this Note the Holder is electing to redeem. Each portion of this Note subject to
redemption by the Company pursuant to this Section 4(b) shall be redeemed by the
Company  at a price  equal to the  greater  of (i) the  Conversion  Amount to be
redeemed  and (ii) the product of (A) the  Conversion  Rate with respect to such

accordance with the provisions of Section 8.

(5) RIGHTS UPON FUNDAMENTAL TRANSACTION.  The Company shall not enter into or be

writing all of the obligations of the Company under this Note in accordance with
the provisions of this Section 5 and each other Transaction Document (as defined
in the Securities Purchase Agreement) pursuant to written agreements in form and
substance  reasonably  satisfactory to the Majority Holders and approved as such
by the Majority  Holders  prior to such  Fundamental  Transaction,  and (ii) the
Successor Entity is a publicly traded  corporation  whose common stock is quoted
on or listed for  trading on an  Eligible  Market.  Upon the  occurrence  of any
Fundamental  Transaction,   the  Successor  Entity  shall  succeed  to,  and  be
substituted  for  (so  that  from  and  after  the  date  of  such   Fundamental
Transaction,  the provisions of this Note referring to the "Company" shall refer
instead to the Successor Entity), and may exercise every right and power of, the
Company an d shall assume all of the  obligations of the Company under this Note
with the same effect as if such  Successor  Entity had been named as the Company
herein. Upon consummation of the Fundamental  Transaction,  the Successor Entity
shall  deliver  to the  Holder  confirmation  that  there  shall be issued  upon
conversion of this Note at any time after the  consummation  of the  Fundamental
Transaction,  in lieu of the  shares  of the  Company's  Common  Stock (or other
securities,  cash, assets or other property)  purchasable upon the conversion of
the  Notes  prior  to  such  Fundamental  Transaction,  such  shares  of  stock,
securities, cash, assets or any other property whatsoever (including warrants or
other purchase or subscription rights) which the Holder would have been entitled
to receive upon the happening of such Fundamental Transaction had this Note been
converted  immediately  prior to such  Fundamental  Transaction,  as adjusted in
accordance  with the  provisions  of this Note.  The  provisions of this Section
shall apply similarly a nd equally to successive  Fundamental  Transactions  and
shall be applied  without regard to any  limitations,  including as set forth in
Section 3(d), on the conversion of this Note.

(6) RIGHTS UPON ISSUANCE OF PURCHASE RIGHTS.  If at any time the Company grants,
issues or sells any Options, Convertible Securities or rights to purchase stock,
warrants,  securities  or other  property pro rata to all record  holders of any
class of Common Stock (the "Purchase Rights"),  then the Holder will be entitled
to acquire,  upon the terms  applicable to such Purchase  Rights,  the aggregate
Purchase  Rights which the Holder could have acquired if the Holder had held the
number of shares of Common Stock  acquirable  upon  complete  conversion of this
Note  (without  taking  into  account any  limitations  or  restrictions  on the
convertibility  of this Note)  immediately  before the date on which a record is
taken for the grant,  issuance or sale of such Purchase  Rights,  or, if no such
record is taken,  the date as of which the record holders of Common Stock are to
be determined for the grant, issue or sale of such Purchase Rights.

(7) RIGHTS UPON ISSUANCE OF OTHER SECURITIES.

     (a)  Adjustment of Conversion  Price upon Issuance of Common Stock.  If and
whenever on or after the  Subscription  Date, the Company issues or sells, or in
accordance  with this Section 7(a) is deemed to have issued or sold,  except any
such  issuances or sales or deemed  issuances or sales to Dolphin  Direct Equity
Partners,  LP, any shares of Common  Stock  (including  the  issuance or sale of
shares of Common Stock owned or held by or for the account of the  Company,  but
excluding shares of Common Stock issued or sold or deemed to have been issued or
sold  by  the  Company  in  connection   with  any  Excluded   Security)  for  a
consideration per share (the "New Securities  Issuance Price") less than a price
(the  "Applicable  Price") equal to the Conversion  Price in effect  immediately
prior  to such  issue  or sale  (the  foregoing  a  "Dilutive  Issuance"),  then
immediately  after such Dilutive  Issuance,  the Conversion Price then in effect
shall be reduced to an amount equal to the New Securities  Issuance  Price.  For
purposes of deter mining the adjusted  Conversion Price under this Section 7(a),
the following shall be applicable:

          (i) Issuance of Options.  If the Company in any manner grants or sells
     any  Options  and the lowest  price per share for which one share of Common
     Stock is issuable  upon the exercise of any such Option or upon  conversion
     or  exchange  or  exercise  of any  Convertible  Securities  issuable  upon
     exercise of such Option is less than the Applicable  Price, then such share
     of Common Stock shall be deemed to be  outstanding  and to have been issued
     and sold by the Company at the time of the  granting or sale of such Option
     for such price per share. For purposes of this Section 7(a)(i), the "lowest
     price per share for which one share of Common  Stock is  issuable  upon the
     exercise of any such Option or upon  conversion  or exchange or exercise of
     any Convertible  Securities issuable upon exercise of such Option" shall be
     equal to the sum of the lowest amounts of  consideration  (if any) received
     or  receivable by the Company with respect to any one share of Common Stock
     upon granting or sale of the Option,  upon exercise of the Option and  upon
     conversion  or exchange or exercise of any  Convertible  Security  issuable
     upon exercise of such Option. No further adjustment of the Conversion Price
     shall be made upon the actual  issuance of such share of Common Stock or of
     such  Convertible  Securities upon the exercise of such Options or upon the
     actual  issuance  of such  Common  Stock upon  conversion  or  exchange  or
     exercise of such Convertible Securities.

          (ii) Issuance of Convertible Securities.  If the Company in any manner
     issues or sells any  Convertible  Securities and the lowest price per share
     for which one share of Common  Stock is issuable  upon such  conversion  or
     exchange or exercise thereof is less than the Applicable  Price,  then such
     share of Common  Stock shall be deemed to be  outstanding  and to have been
     issued and sold by the Company at the time of the  issuance of sale of such
     Convertible  Securities for such price per share.  For the purposes of this
     Section 7(a)(ii),  the "price per share for which one share of Common Stock
     is issuable upon such conversion or exchange or exercise" shall be equal to
     the sum of the  lowest  amounts  of  consideration  (if  any)  received  or
     receivable  by the Company  with  respect to any one share of Common  Stock
     upon  the  issuance  or sale  of the  Convertible  Security  and  upon  the
     conversion or exchange or exercise of such Convertible Security. No further
     adjustment of the Conversion  Price shall be made upon the actual iss uance
     of such share of Common  Stock upon  conversion  or exchange or exercise of
     such  Convertible  Securities,  and if any  such  issue  or  sale  of  such
     Convertible  Securities  is made upon  exercise  of any  Options  for which
     adjustment of the  Conversion  Price had been or are to be made pursuant to
     other  provisions  of this  Section  7(a),  no  further  adjustment  of the
     Conversion Price shall be made by reason of such issue or sale.

          (iii)  Change in Option Price or Rate of  Conversion.  If the purchase
     price provided for in any Options,  the additional  consideration,  if any,
     payable upon the issue, conversion, exchange or exercise of any Convertible
     Securities, or the rate at which any Convertible Securities are convertible
     into or  exchangeable  or exercisable  for Common Stock changes  (excluding
     circumstances   limited   to  where   such   purchase   price,   additional
     consideration  or rate is only subject to prospective  change) at any time,
     the Conversion Price in effect at the time of such change shall be adjusted
     to the  Conversion  Price  which would have been in effect at such time had
     such Options or Convertible  Securities  provided for such changed purchase
     price, additional consideration or changed conversion rate, as the case may
     be, at the time  initially  granted,  issued or sold.  For purposes of this
     Section 7(a)(iii),  if the terms of any Option or Convertible Security that
     was outstanding as of the Closing Date are changed in the manner de scribed
     in the  immediately  preceding  sentence,  then such Option or  Convertible
     Security and the Common Stock deemed issuable upon exercise,  conversion or
     exchange thereof shall be deemed to have been issued as of the date of such
     change.  No adjustment  shall be made if such adjustment would result in an
     increase of the Conversion Price then in effect.

          (iv)  Calculation  of  Consideration  Received.  In case any Option is
     issued  in  connection  with the issue or sale of other  securities  of the
     Company,  together  comprising  one  integrated  transaction  in  which  no
     specific consideration is allocated to such Options by the parties thereto,
     the Options will be deemed to have been issued for a consideration of $.01.
     If any Common Stock,  Options or Convertible  Securities are issued or sold
     or deemed to have been issued or sold for cash, the consideration  received
     therefor  will be  deemed  to be the net  amount  received  by the  Company
     therefor. If any Common Stock, Options or Convertible Securities are issued
     or  sold  for  a   consideration   other  than  cash,  the  amount  of  the
     consideration  other than cash  received  by the  Company  will be the fair
     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 Closing Sale Price of such  securities  on the date of
     receipt. If any Common Stock, Options or Convertible  Securities are issued
     to the owners of the non-surviving  entity in connection with any merger in
     which the  Company is the  surviving  entity,  the amount of  consideration
     therefor  will be deemed to be the fair  value of such  portion  of the net
     assets and business of the non-surviving  entity as is attributable to such
     Common Stock,  Options or Convertible  Securities,  as the case may be. The
     fair  value of any  consideration  other  than cash or  securities  will be
     determined jointly by the Company and the Majority Holders. If such parties
     are unable to reach agreement  within ten (10) days after the occurrence of
     an event  requiring  valuation (the "Valuation  Event"),  the fair value of
     such  consideration  will be determined within five (5) Business Days after
     the tenth day following the Valuation  Event by an  independent,  reputable
     appraiser  jointly  selected by the Company and the Majority  Holders.  The
     determination  of such  appraiser  shall be deemed binding upon all parties
     absent  manifest error and the fees and expenses of such appraiser shall be
     borne by the Company.

          (v)  Record  Date.  If the  Company  takes a record of the  holders of
     Common Stock for the purpose of entitling them (A) to receive a dividend or
     other  distribution  payable in Common  Stock,  Options  or in  Convertible
     Securities  or (B) to subscribe for or purchase  Common  Stock,  Options or
     Convertible Securities, then such record date will be deemed to be the date
     of the issue or sale of the Common Stock deemed to have been issued or sold
     upon  the  declaration  of  such  dividend  or the  making  of  such  other
     distribution  or the date of the granting of such right of  subscription or
     purchase, as the case may be.

     (b)  Adjustment of Conversion  Price upon  Subdivision  or  Combination  of
Common  Stock.  If the  Company  at any time on or after the  Subscription  Date
subdivides (by any stock split, stock dividend,  recapitalization  or otherwise)
one or more  classes of its  outstanding  shares of Common  Stock into a greater
number of  shares,  the  Conversion  Price in effect  immediately  prior to such
subdivision will be  proportionately  reduced.  If the Company at any time on or
after the  Subscription  Date combines (by  combination,  reverse stock split or
otherwise) one or more classes of its outstanding  shares of Common Stock into a
smaller number of shares,  the Conversion Price in effect  immediately  prior to
such combination will be proportionately increased.

     (c) Other  Events.  If any event  occurs  of the type  contemplated  by the
provisions of this Section 7 but not expressly  provided for by such  provisions
(including,  without  limitation,  the  granting of stock  appreciation  rights,
phantom stock rights or other rights with equity  features,  other than pursuant
to an Approved Stock Plan),  then the Company's  Board of Directors will make an
appropriate  adjustment in the  Conversion  Price so as to protect the rights of
the Holder under this Note;  provided that no such  adjustment will increase the
Conversion Price as otherwise determined pursuant to this Section 7.

     (d) This Note Deemed  Outstanding.  If during the period  beginning  on and
including the Subscription Date and ending on the date immediately preceding the
Issuance  Date,  the Company  entered into,  or in accordance  with Section 7(a)
would have been deemed to have entered into (had this Note been  outstanding  at
such  time),  any  Dilutive  Issuance  or  if  any  of  the  events  or  actions
contemplated  by  Sections  7(b) or (c) shall  have  occurred,  then  solely for
purposes of determining any adjustment  under this Section 7 as a result of such
Dilutive Issuance, deemed Dilutive Issuance, action or event, this Note shall be
deemed to have been  outstanding  at the time of each  such  Dilutive  Issuance,
deemed Dilutive Issuance, action or event.

     (e)  Security.  This Note is  secured  to the  extent and in the manner set
forth in the Security Agreement and the Pledge Agreements and is subordinated to
the extent and in the manner set forth in the Subordination Agreement.

     (f)  Non-circumvention.  The Company  hereby  covenants and agrees that the
Company will not, by amendment of its  Certificate of  Incorporation,  Bylaws or
through any reorganization, transfer of assets, consolidation, merger, scheme of
arrangement,  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
of  this  Note,  and  will  at all  times  in good  faith  carry  out all of the
provisions  of this Note and take all action as may be  required  to protect the
rights of the Holder of this Note.

     (g) Reservation of Authorized Shares.

          (i)  Reservation.  The  Company  initially  shall  reserve  out of its
     authorized and unissued Common Stock a number of shares of Common Stock for
     each of the Notes equal to 130% of the Conversion  Rate with respect to the
     Conversion Amount of each such Note as of the Issuance Date. So long as any
     of the Notes are  outstanding,  the Company shall take all action necessary
     to reserve and keep  available out of its  authorized  and unissued  Common
     Stock,  solely for the purpose of effecting  the  conversion  of the Notes,
     130% of the number of shares of Common  Stock as shall from time to time be
     necessary  to effect the  conversion  of all of the Notes then  outstanding
     (the  "Required  Reserve  Amount").  The initial number of shares of Common
     Stock reserved for conversions of the Notes and each increase in the number
     of shares so reserved  shall be allocated pro rata among the holders of the
     Notes based on the principal amount of the Notes held by each holder at the
     Closing (as defined in the Securities  Purchase  Agreement) or increase  in
     the number of reserved shares,  as the case may be (the  "Authorized  Share
     Allocation").  In the event that a holder shall sell or otherwise  transfer
     any of such holder's Notes,  each transferee  shall be allocated a pro rata
     portion of such holder's Authorized Share Allocation.  Any shares of Common
     Stock  reserved and  allocated to any Person which ceases to hold any Notes
     shall be allocated to the remaining holders of Notes, pro rata based on the
     principal amount of the Notes then held by such holders.

          (ii) Insufficient  Authorized  Shares. If at any time while any of the
     Notes remain  outstanding the Company does not have a sufficient  number of
     authorized and unreserved  shares of Common Stock to satisfy its obligation
     to reserve for issuance  upon  conversion of the Notes at least a number of
     shares of Common Stock equal to the Required Reserve Amount (an "Authorized
     Share  Failure"),  then the  Company  shall  immediately  take  all  action
     necessary to increase the Company's authorized shares of Common Stock to an
     amount  sufficient  to allow the  Company to reserve the  Required  Reserve
     Amount for the Notes then  outstanding.  Without limiting the generality of
     the  foregoing  sentence,  as soon as  practicable  after  the  date of the
     occurrence of an Authorized  Share  Failure,  but in no event later than 90
     days after the occurrence of such  Authorized  Share  Failure,  the Company
     shall hold a meeting of its shareholders for the approval of an increase in
     the number of authorized  shares of Common Stock.  In connection  with such
     meeting,  the Company shall provide each shareholder with a proxy statement
     and shall use its best  efforts to solicit  its  shareholders'  approval of
     such increase in  authorized  shares of Common Stock and to cause its board
     of  directors  to  recommend  to the  shareholders  that they  approve such
     proposal.

(8) HOLDER'S REDEMPTIONS.

     (a) Mechanics.  The Company shall deliver the  applicable  Event of Default
Redemption  Price to the Holder  within five  Business  Days after the Company's
receipt of the Holder's Event of Default  Redemption  Notice in accordance  with
the  terms  hereof.  In the  event  of any  redemption  of less  than all of the
Conversion  Amount of this Note,  the Company  shall  execute and deliver to the
Holder a new  Note  representing  the  outstanding  Principal  that has not been
redeemed. In the event that the Company does not pay the Redemption Price to the
Holder within the time period  required,  at any time  thereafter  and until the
Company  pays such unpaid  Redemption  Price in full,  the Holder shall have the
option, in lieu of redemption,  to require the Company to promptly return to the
Holder all or any portion of this Note  representing the Conversion  Amount that
was submitted for redemption and for which the applicable  Redemption  Price has
not been paid.  Upon the Company's  receipt of written notice of the exercise of
such opt ion, (x) the Event of Default  Redemption Notice shall be null and void
with respect to such Conversion Amount, (y) the Company shall immediately return
this Note, or shall execute and deliver,  a new Note to the Holder  representing
such  Conversion  Amount and (z) the  Conversion  Price of this Note or such new
Notes shall be adjusted to the lesser of (A) the  Conversion  Price as in effect
on the date on which the Event of  Default  Redemption  Notice is voided and (B)
the lowest  Closing Bid Price during the period  beginning on and  including the
date on which the Event of Default Redemption Notice is delivered to the Company
and ending on and  including  the date on which the Event of Default  Redemption
Notice is voided.

     (b) Redemption by Other Holders.  Upon the Company's receipt of notice from
any of the holders of the Other Notes for redemption or repayment as a result of
an event or  occurrence  substantially  similar  to the  events  or  occurrences
described in Sections 4(b) (each,  an "Other  Redemption  Notice"),  the Company
shall promptly forward to the Holder by facsimile a copy of such notice.  If the
Company  receives  an Event of Default  Redemption  Notice and one or more Other
Redemption Notices,  during the period beginning on and including the date which
is three  Business Days prior to the Company's  receipt of the Holder's Event of
Default  Redemption  Notice and ending on and  including the date which is three
Business  Days  after the  Company's  receipt of the  Holder's  Event of Default
Redemption  Notice and the Company is unable to redeem all  principal,  interest
and other amounts designated in such Event of Default Redemption Notice and such
Other Redemption Notices received during such seven Business Day period,  then t
he Company shall redeem a pro rata from each holder of the Notes  (including the
Holder) based on the  principal  amount of the Notes  submitted  for  redemption
pursuant to such Event of Default  Redemption  Notice and such Other  Redemption
Notices received by the Company during such seven Business Day period.

     (c)  Restriction On Redemption  and Dividends.  Until all of the Notes have
been converted,  redeemed or otherwise satisfied in accordance with their terms,
the Company shall not, and the Company shall not permit any of its  Subsidiaries
to,  directly  or  indirectly,  redeem,  repurchase  or  declare or pay any cash
dividend or  distribution on its capital stock without the prior express written
consent of the Majority Holders.

(9) VOTING RIGHTS.  The Holder shall have no voting rights as the holder of this
Note,  except as  required  by law,  including  but not  limited to the  General
Corporation  Law of the State of  Delaware,  and as  expressly  provided in this
Note.

(10) COVENANTS.

     (a) Rank.  Except as  expressly  provided  otherwise  in the  Subordination
Agreement,  all  payments due under this Note (a) shall rank pari passu with all
other Notes issued in exchange,  transfer or  replacement  of a Note,  (b) shall
rank junior to the Existing  Senior  Indebtedness,  and (c) shall rank senior to
all  other  Indebtedness  of  the  Company  and  its  subsidiaries,  except  (i)
capitalized  leases (A) as are included as such in accordance with United States
generally accepted accounting  principles,  consistently applied, on the balance
sheet of the Company  contained in its  Quarterly  Report for the quarter  ended
March 31, 2005 as  originally  filed with the SEC or (B) that do not require the
payment  in any  fiscal  year of the  Company  of an  aggregate  amount  for all
capitalized  leases  not  described  in clause (A) of more than  $50,000  and in
nature and other  circumstances  thereof  consistent with past practice and (ii)
contingent obligations.

     (b) Incurrence of  Indebtedness.  So long as this Note is outstanding,  the
Company shall not, and the Company shall not permit any Subsidiary to,  directly
or indirectly,  incur or guarantee,  assume or suffer to exist any  Indebtedness
senior  in right of  payment  to this  Note,  other  than  the  Existing  Senior
Indebtedness.

     (c) Existence of Liens.  So long as this Note is  outstanding,  the Company
shall not, and the Company shall not permit any of its Subsidiaries to, directly
or  indirectly,  allow or suffer to exist any mortgage,  lien,  pledge,  charge,
security  interest  or  other  encumbrance  upon or in any  property  or  assets
(including  accounts  and  contract  rights)  owned by the Company or any of its
Subsidiaries (collectively,  "Liens"), other than the security interest securing
the Existing Senior  Indebtedness  and Permitted Liens (as defined in the Senior
Credit Agreement as in effect on the date hereof).

(11) PARTICIPATION. The Holder, as the holder of this Note, shall be entitled to
such dividends paid and distributions made to the holders of Common Stock to the
same extent as if the Holder had converted  this Note into Common Stock (without
regard to any  limitations on conversion  herein or elsewhere) and had held such
shares of Common Stock on the record date for such dividends and  distributions.
Payments  under  the  preceding  sentence  shall be made  concurrently  with the
dividend or distribution to the holders of Common Stock.

(12) CHANGES OR AMENDMENTS TO NOTES.  The Notes shall only be changed or amended
upon the written consent of the Majority Holders.

(13)  TRANSFER.  Subject to the  provisions  of the legends on the first page of
this Note, this Note may be offered, sold, assigned or transferred by the Holder
without the consent of the Company, provided that the transferee delivers to the
Company an undertaking  to comply with the covenants  contained in Sections 7(n)
and (o) of the Securities Purchase Agreement.

(14) REISSUANCE OF THIS NOTE.

     (a) Transfer. If this Note is to be transferred, the Holder shall surrender
this Note to the Company, whereupon the Company will forthwith issue and deliver
upon the order of the  Holder a new Note (in  accordance  with  Section  14(d)),
registered as the Holder may request,  representing  the  outstanding  Principal
being  transferred  by the  Holder  and,  if less  then the  entire  outstanding
Principal is being transferred, a new Note (in accordance with Section 14(d)) to
the Holder  representing the outstanding  Principal not being  transferred.  The
Holder and any assignee, by acceptance of this Note, acknowledge and agree that,
by reason  of the  provisions  of  Section  3(c)(iii)  and this  Section  14(a),
following  conversion or redemption of any portion of this Note, the outstanding
Principal  represented by this Note may be less than the Principal stated on the
face of this Note.

     (b) Lost, Stolen or Mutilated Note. Upon receipt by the Company of evidence
reasonably  satisfactory  to the  Company  of the loss,  theft,  destruction  or
mutilation of this Note, and, in the case of loss, theft or destruction,  of any
indemnification undertaking by the Holder to the Company reasonably satisfactory
to the  Company  but in no event  requiring  the  posting of any bond or similar
security and, in the case of mutilation, upon surrender and cancellation of this
Note,  the  Company  shall  execute  and  deliver  to the  Holder a new Note (in
accordance with Section 14(d)) representing the outstanding Principal.

     (c)  Note   Exchangeable   for  Different   Denominations.   This  Note  is
exchangeable,  upon the surrender by the Holder at the  principal  office of the
Company,  for a new Note or Notes  (in  accordance  with  Section  14(d)  and in
principal   amounts  of  at  least  $50,000)   representing  the  aggregate  the
outstanding  Principal of this Note,  and each such new Note will represent such
portion of such outstanding Principal as is designated by the Holder at the time
of such surrender.

     (d) Issuance of New Notes.  Whenever the Company is required to issue a new
Note  pursuant  to the  terms of this  Note,  such new Note (i) shall be of like
tenor with this Note, (ii) shall represent, as indicated on the face of such new
Note, the Principal  remaining  outstanding  (or in the case of a new Note being
issued pursuant to Section 14(a) or Section 14(c),  the Principal  designated by
the Holder which, when added to the principal represented by the other new Notes
issued in connection with such issuance, does not exceed the Principal remaining
outstanding  under this Note  immediately  prior to such issuance of new Notes),
(iii) shall have an issuance  date,  as  indicated on the face of such new Note,
which is the same as the  Issuance  Date of this Note,  (iv) shall have the same
rights and conditions as this Note, and (v) shall represent  accrued Interest on
the Principal of this Note from the Issuance Date.

(15) REMEDIES,  CHARACTERIZATIONS,  OTHER  OBLIGATIONS,  BREACHES AND INJUNCTIVE
RELIEF.  The remedies  provided in this Note shall be cumulative and in addition
to all other  remedies  available  under  this  Note and the  other  Transaction
Documents at law or in equity (including a decree of specific performance and/or
other injunctive  relief),  and nothing herein shall limit the Holder's right to
pursue actual and consequential damages for any failure by the Company to comply
with the terms of this Note.  Amounts  set forth or  provided  for  herein  with
respect to payments, conversion and the like (and the computation thereof) shall
be the amounts to be received by the Holder and shall not, except as provided in
the Security Agreement or otherwise expressly provided herein, be subject to any
other  obligation  of the  Company  (or the  performance  thereof).  The Company
acknowledges  that  a  breach  by it of its  obligations  hereunder  will  cause
irreparable  harm to the Holder  and that the remedy at law for any such  breach
may be inadequate.  The Company therefore  agrees that, in the event of any such
breach or threatened  breach,  the Holder shall be entitled,  in addition to all
other available remedies, to an injunction  restraining any breach,  without the
necessity of showing  economic loss and without any bond or other security being
required.

(16) PAYMENT OF  COLLECTION,  ENFORCEMENT  AND OTHER  COSTS.  If (a) the Company
defaults  in any of its  obligations  under this Note and this Note is placed in
the hands of an attorney  for  collection  or  enforcement  or is  collected  or
enforced  through any legal  proceeding or the Holder  otherwise takes action to
collect amounts due under this Note or to enforce the provisions of this Note or
(b) there occurs any bankruptcy, reorganization,  receivership of the Company or
other  proceedings  affecting  Company  creditors'  rights and involving a claim
under this Note, then the Company shall pay the costs reasonably incurred by the
Holder for such  collection,  enforcement  or action or in connection  with such
bankruptcy, reorganization, receivership or other proceeding, including, but not
limited to, reasonable attorneys' fees and disbursements.

(17) CONSTRUCTION;  HEADINGS. This Note shall be deemed to be jointly drafted by
the Company and the Holder and shall not be construed  against any person as the
drafter  hereof.  The headings of this Note are for convenience of reference and
shall not form part of, or affect the interpretation of, this Note.

(18) FAILURE OR  INDULGENCE  NOT WAIVER.  No failure or delay on the part of the
Holder in the exercise of any power, right or privilege  hereunder shall operate
as a waiver thereof, nor shall any single or partial exercise of any such power,
right or privilege  preclude other or further  exercise  thereof or of any other
right, power or privilege.

(19)  DISPUTE  RESOLUTION.  If the  Majority  Holders  at any time  dispute  the
determination  of the Closing Bid Price,  the Closing Sale Price, the arithmetic
calculation of the Conversion Rate or the Event of Default Redemption Price, the
Majority Holders may give the Company written notice of such dispute (a "Dispute
Notice").  The  Company  shall  submit its  determinations,  related  arithmetic
calculations and other information  relating thereto to the Majority Holders via
facsimile  within one  Business  Day of receipt of the  Dispute  Notice.  If the
Majority Holders and the Company are unable to agree upon such  determination or
calculation within one Business Day of such disputed determination or arithmetic
calculation  being  submitted to the Majority  Holders,  then the Company shall,
within one Business Day submit via facsimile (a) the disputed  determination  of
the  Closing Bid Price or the Closing  Sale Price to an  independent,  reputable
investment bank selected by the Majority  Holders and subject to approval by the
Company or (b) the disputed  arithmetic  calculation  of the Conversion  Rate or
the Redemption Price to an independent  accounting firm selected by the Majority
Holders and subject to approval by the Company.  The Company,  at the  Company's
expense, shall cause the investment bank or the accountant,  as the case may be,
to perform the  determinations  or  calculations  and notify the Company and the
Majority  Holders of the results no later than five  Business Days from the time
it receives the disputed determinations or calculations.  Such investment bank's
or  accountant's  determination  or  calculation,  as the case may be,  shall be
binding upon all parties absent demonstrable error.

(20) NOTICES; PAYMENTS.

     (a)  Notices.  Whenever  notice is  required  to be given  under this Note,
unless otherwise provided herein,  such notice shall be given in accordance with
the Securities Purchase  Agreement.  The Company will give written notice to the
Holder (i) as soon as  practicable  and in no event later than two Business Days
following any  adjustment of the Conversion  Price,  setting forth in reasonable
detail, and certifying, the calculation of such adjustment and (ii) at least ten
Business Days prior to the date on which the Company closes its books or takes a
record (A) with respect to any dividend or  distribution  upon the Common Stock,
(B) with respect to any pro rata  subscription  offer to holders of Common Stock
or  (C)  for  determining  rights  to  vote  with  respect  to  any  Fundamental
Transaction,  dissolution  or  liquidation,  provided  in each  case  that  such
information  shall be made known to the public prior to or in  conjunction  with
such notice being provided to the Holder.

     (b) Payments.  Whenever any payment of cash is to be made by the Company to
any Person  pursuant to this Note, such payment shall be made in lawful money of
the United  States of America by a check drawn on the account of the Company and
sent via overnight  courier service to such Person at such address as previously
provided to the Company in writing  (which  address,  in the case of each of the
Purchasers,  shall  initially be as set forth on the Schedule of Buyers attached
to the  Securities  Purchase  Agreement);  provided that the Holder may elect to
receive a payment of cash via wire transfer of  immediately  available  funds by
providing the Company with prior written notice setting out such request and the
Holder's wire transfer instructions.  Whenever any amount expressed to be due by
the terms of this Note is due on any day which is not a Business  Day,  the same
shall instead be due on the next  succeeding day which is a Business Day and, in
the case of any Interest  Date which is not the date on which this Not e is paid
in full,  the  extension of the due date thereof shall not be taken into account
for purposes of determining the amount of Interest due on such date.

(21)  CANCELLATION.  After all Principal,  accrued Interest and other amounts at
any time owed on this Note has been paid in full, this Note shall  automatically
be deemed  canceled,  shall be surrendered to the Company for  cancellation  and
shall not be reissued.

(22) WAIVER OF NOTICE. To the extent permitted by law, the Company hereby waives
demand, notice, protest and all other demands and notices in connection with the
delivery, acceptance,  performance,  default or enforcement of this Note and the
Securities Purchase Agreement.

(23)  GOVERNING  LAW.  This Note shall be construed  and enforced in  accordance
with, and all questions  concerning the construction,  validity,  interpretation
and  performance  of this Note shall be governed  by, the  internal  laws of the
State of New York, without giving effect to any choice of law or conflict of law
provision or rule (whether of the State of New York or any other  jurisdictions)
that would cause the application of the laws of any jurisdictions other than the
State of New York.

(24) JURISDICTION.  The Company hereby  irrevocably  consents and submits to the
exclusive  jurisdiction  of the United  States  District  Court for the Southern
District of New York in connection  with any dispute  arising out of or relating
to this Note or the transactions contemplated hereby or by any other Transaction
Document,  waives any  objection  to venue in such  District  (unless such court
lacks  jurisdiction  with respect to such  dispute,  in which case,  the Company
irrevocably  consents to the jurisdiction of the courts of the State of New York
located  in New York  County in  connection  with such  dispute  and  waives any
objection  to venue in the County of New York),  and agrees that  service of any
summons,  complaint,  notice or other  process  relating to such  dispute may be
