                                       8

transfer of the Shares,  Warrants and Warrant  Shares unless they are registered
or such  registration  is not  required  in the  opinion  of counsel in form and
substance satisfactory to the Company.

      (f)  FOREIGN  INVESTOR  REPRESENTATION.  If the  Investor  is not a  "U.S.
person"  (as such term is defined in Rule  902(k) of  Regulation  S  promulgated
under the Securities Act), such Investor hereby represents that it has satisfied
itself as to the full  observance of the laws of its  jurisdiction in connection
with any  invitation to subscribe for the Shares and Warrants or any use of this
Agreement,  including (i) the legal requirements within its jurisdiction for the
purchase  of the Shares and  Warrants,  (ii) any foreign  exchange  restrictions
applicable to such purchase,  (iii) any  governmental or other consents that may
need to be obtained, and (iv) the income tax and other tax consequences, if any,
that may be relevant to the purchase,  holding,  redemption, sale or transfer of
the Shares and Warrants.  Such Investor's  subscription and payment for, and its
continued beneficial ownership of the Shares and Warrants,  will not violate any
applicable securities or other laws of its jurisdiction.

      (g) DOMICILE.  The Investor is a bona fide resident and domiciliary (not a
temporary or transient resident) of the state indicated on Schedule 1 hereto and
he, she or it has no present intention of becoming a resident of any other state
or jurisdiction.

      (h) NO NEED FOR LIQUIDITY.  The Investor's aggregate holding of securities
that are  "restricted  securities"  or otherwise  not readily  marketable is not
excessive in view of the  Investor's net worth and financial  circumstances  and
the purchase of the Shares and Warrants will not cause such commitment to become
excessive.

      (i) INDEPENDENT  ADVICE.  The Investor  understands that the Company urges
the Investor to seek independent  advice from professional  advisors relating to
the  suitability for the Investor of an investment in the Company in view of the
Investor's   overall   financial  needs  and  with  respect  to  legal  and  tax
implications of such an investment.

5.    RELIANCE.  The  Investor understands  that  the Company  may  rely  on the
representations and warranties in Section 4 in determining whether to permit the
Investor  to  purchase  the  Shares  and   Warrants.   If  for  any  reason  any
representations  and  warranties  are no longer true and  accurate  prior to the
Closing Date,  the Investor will give the Company  prompt  written notice of the
inaccuracy. By signing below, the Investor represents that the Investor has read
and confirmed  the truth and accuracy of each of the  foregoing  representations
and warranties.

6.    ADDITIONAL COVENANTS OF THE PARTIES.

      (a) INDEMNIFICATION.  Each party agrees to indemnify and hold harmless the
other parties hereto and each of its directors,  officers, agents and affiliates
(as applicable) from and against any and all loss, damage or liability due to or
arising out of a breach of any representation, warranty or covenant of contained
in this Agreement and made by the indemnifying  party,  provided  however,  that
this  Section  6 shall  not be  construed  to  require  any  Investor  (i) to so
indemnify and hold harmless any other  Investor or (ii) to so indemnify and hold
harmless the Company for any such breach by any other Investor. The liability of
any  Investor to provide  indemnification  pursuant  to this  Section 6 shall be
limited to the amount such Investor paid to the Company for the purchase of such
Investor's Shares and Warrants.

                                       9

      (b) PLEDGE OF  SECURITIES.  The Company  acknowledges  and agrees that the
Shares,  Warrants and Warrant Shares may be pledged by an Investor in connection
with a bona fide margin agreement or other loan or financing arrangement that is
secured by the Shares  Warrants  or Warrant  Shares.  The pledge of the  Shares,
Warrants  or  Warrant  Shares  shall  not be deemed  to be a  transfer,  sale or
assignment of the Shares, Warrants or Warrant Shares hereunder,  and no Investor
effecting a pledge of Shares,  Warrants or Warrant  Shares  shall be required to
provide the Company with any notice  thereof or  otherwise  make any delivery to
the Company pursuant to this Agreement or any other Transaction  Agreement.  The
Company hereby agrees to execute and deliver such  documentation as a pledgee of
the Shares, Warrants or Warrant Shares may reasonably request in connection with
a pledge of the thereof to such pledgee by an Investor.

      (c) SECURITIES  LAWS  DISCLOSURE;  PUBLICITY.  The Company shall (i) on or
promptly  after  the  Closing  Date,  issue a press  release  acceptable  to SDS
disclosing the  transactions  contemplated  hereby,  and (ii) promptly after the
Closing  Date,  file with the  Commission  a Report on Form 8-K  disclosing  the
transactions  contemplated hereby. Except as provided in the preceding sentence,
neither  the  Company nor the  Investors  shall make any press  release or other
publicity  about the terms of this  Agreement or the  transactions  contemplated
hereby without the prior approval of the other unless otherwise required by law,
regulation or the rules of the Commission.  In addition, the Company agrees that
it shall not  disclose,  and shall not  include  in any  public  filing or other
announcement, the name of any Investor, unless expressly agreed to in writing by
such Investor or unless and until such disclosure is, in the reasonable  opinion
of counsel to the Company,  required by law or applicable  regulation,  and then
only to the extent of such requirement.

      (d) LISTING.  The Company shall promptly  secure the listing of the Shares
and  Warrant  Shares  (and  any  Registrable   Securities  (as  defined  in  the
Registration Rights Agreement) that may from time to time be issued or issuable)
upon each national securities exchange or automated quotation system or bulletin
board,  if any,  upon which shares of Common  Stock are then listed  (subject to
official  notice of issuance)  and, so long as any of the Investors  owns any of
the Registrable  Securities (as defined in the Registration  Rights  Agreement),
shall maintain,  so long as any other shares of Common Stock shall be so listed,
such listing of all Shares issued  pursuant to this Agreement and Warrant Shares
issuable  upon  exercise  of or  otherwise  pursuant  to the  Warrants,  and any
Registrable  Securities (as defined in the Registration  Rights  Agreement) that
may from time to time be issued or issuable. To the extent that any Common Stock
is so listed,  the Company will obtain and, so long as the Investor  owns any of
the Registrable  Securities (as defined in the Registration  Rights  Agreement),
maintain the listing and trading of its Common Stock on the Nasdaq SmallCap, the
Nasdaq  National  Market,  the New York Stock  Exchange,  or the American  Stock
Exchange and will comply in all respects  with the Company's  reporting,  filing
and other  obligations  under the bylaws or rules of any  exchanges or automated
quotation systems on which the Common Stock is then listed.

7.    RESTRICTIVE LEGENDS AND STOP-TRANSFER ORDERS.

      (a) LEGEND.  The  instruments  representing  the Shares,  Warrants and, if
applicable, Warrant Shares shall bear the following legend or similar legend (as
well as any legends  required by  applicable  state and  federal  corporate  and
securities laws):

          THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
          UNDER THE  SECURITIES  ACT OF 1933 (THE "ACT") AND MAY NOT
          BE  OFFERED,  SOLD OR  OTHERWISE  TRANSFERRED,  PLEDGED OR
          HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR,
          IN  THE   OPINION  OF   COUNSEL  IN  FORM  AND   SUBSTANCE
          SATISFACTORY  TO THE  ISSUER  OF  THESE  SECURITIES,  SUCH
          OFFER,  SALE OR TRANSFER,  PLEDGE OR  HYPOTHECATION  IS IN
          COMPLIANCE THEREWITH.

      (b) REMOVAL OF LEGEND AND TRANSFER RESTRICTIONS.  Any legend endorsed on a
certificate  pursuant to this Section 7 shall be removed,  and the Company shall
issue a certificate  without such legend to the holder of such Shares or Warrant
Shares  if  (i)  such  Shares  or  Warrant  Shares  are  resold  pursuant  to  a
registration  statement under the Securities  Act, and a prospectus  meeting the
requirements  of  Section  11 of the  Securities  Act  is  delivered  or  deemed
delivered to the purchaser of such Shares or Warrant Shares, (ii) if such holder
satisfies the  requirements  of Rule 144(k) or (iii) if such holder provides the
Company  with an  opinion of  counsel  for such  holder of the Shares or Warrant
Shares,  reasonably  satisfactory  to the  Company,  to the effect  that a sale,
transfer  or  assignment  of such Shares or Warrant  Shares may be made  without
registration.

8.    PRICE  PROTECTION. If the Company issues or sells any shares of its Common
Stock or Common Stock  Equivalents,  other than Excluded Shares (as that term is
defined  below)  ("ADDITIONAL  SHARES") at any time after the  Closing  Date and
prior to June 30, 2004 (the "ADJUSTMENT  PERIOD") for a consideration  per share
(the  "DILUTIVE  PRICE")  (a) less than the Share Price (as  adjusted  for stock
splits,  stock  dividends and the like) and (b) if  Additional  Shares have been
previously issued during the Adjustment Period with respect to which the Company
has fully complied with this Section 8, then also less than the lowest  Dilutive
Price (as adjusted for stock splits, stock dividends and the like) at which such
Additional Shares have been previously issued during the Adjustment Period, then
the Company  will issue to each  Investor a number of shares,  if  positive,  of
Common Stock to such Investor determined by the following formula:

                         X  =  (A * B / C) -  (A + D)

          Where:   X    =   the number of shares of Common Stock to be issued to
                            the  Investor, rounded to the nearest whole number;

                   A    =   the number of Shares (as  adjusted for stock splits,
                            stock dividends and the like) then held by such
                            Investor;

                                       11
<PAGE>

                   B    =   the Share Price (as adjusted for stock splits, stock
                            dividends and the like);

                   C    =   the applicable Dilutive Price; and

                   D    =   the  aggregate  number of shares of Common Stock (as
                            adjusted  for  stock splits, stock dividends and the
                            like) issued  to  the  Investor  pursuant  to   this
                            Section  8 prior to the date  of such determination.

For purposes of this Agreement,  the term "EXCLUDED SHARES" means: (i) shares of
Common Stock  issuable or issued after the Closing Date to officers,  employees,
consultants  or  directors  of the  Company  directly  or  pursuant  to a  stock
purchase,  stock option,  restricted stock or other written compensation plan or
agreement approved by the Board of Directors of the Company (the "BOARD");  (ii)
shares of Common Stock issued or issuable after the Closing Date,  primarily for
non-equity  financing  purposes  and as  approved  by the  Board,  to  financial
institutions  or lessors in  connection  with  commercial  credit  arrangements,
equipment  financings or similar transactions or to vendors of goods or services
or  customers;  (iii)  shares of Common  Stock  issuable  upon (a)  exercise  of
warrants,  options,  notes or other rights to acquire securities of the Company,
in each case,  outstanding  on the date of this  Agreement,  (b)  conversion  of
shares of the Company's  Preferred Stock, par value $0.01 per share  outstanding
on the date of this Agreement or (c) exchange of promissory  notes issued by the
Company  outstanding  on the  date of this  Agreement;  (iv)  capital  stock  or
warrants or options to purchase  capital  stock issued in  connection  with bona
fide  acquisitions,  mergers  or  similar  transactions,  the terms of which are
approved  by the  Board;  (v)  shares of Common  Stock  issued  or  issuable  to
licensors of technology  of the Company to pay expenses,  royalties or milestone
payments  for which the  Company is  obligated  under any  licensing  or related
agreement;  (vi) shares of Common  Stock  issuable  or issued  pursuant to stock
splits,  stock dividends and the like, or (vii) shares of Common Stock issued or
issuable by way of dividend or other distribution on Excluded Shares.

If the Company shall issue or sell any warrants or other rights to subscribe for
or purchase any additional shares of Common Stock or any securities  convertible
into shares of Common Stock  (collectively,  "COMMON STOCK EQUIVALENTS")  during
the  Adjustment  Period,  whether  or not the  rights  to  exchange  or  convert
thereunder are  immediately  exercisable,  and the effective price per share for
which Common Stock is issuable upon the exercise, exchange or conversion of such
Common Stock Equivalents shall be less than (i) the Share Price (as adjusted for
stock splits,  stock dividends and the like) and (ii) if Additional  Shares have
been  previously  issued during the Adjustment  Period with respect to which the
Company has fully  complied  with this Section 8, then also less than the lowest
Dilutive Price (as adjusted for stock splits,  stock  dividends and the like) at
which such Additional  Shares have been previously  issued during the Adjustment
Period,  then the Company  shall issue to the Investor  that number of shares of
Common Stock that would be issuable pursuant to this Section 8 on the basis that
the maximum number of additional shares of Common Stock issuable pursuant to all
such  Common  Stock  Equivalents  shall  be  deemed  to  have  been  issued  and
outstanding and the Company shall have received all of the consideration payable
therefor,  if any, as of the date of the actual  issuance  of such Common  Stock
Equivalents.  No further  issuances  shall be made under this Section 8 upon the
actual issue of such Common Stock upon the  exercise,  conversion or exchange of
such  Common  Stock  Equivalents,  unless  such  actual  issue is at a per share
consideration  lower than the  Dilutive  Price used for  purposes of the initial
adjustment pursuant to this Section 8.

9.    PARTICIPATION RIGHTS.

      (a) Subject to the terms and  conditions  specified in this Section 9, the
Company  hereby  grants to each  Investor a right of first offer with respect to
sales by the  Company of  Additional  Shares,  which in no event  shall  include
Excluded  Shares,  on the same terms and conditions as offered by the Company to
the other purchasers of such Additional Shares. If the Company proposes to offer
any  Additional  Shares for sale at any time after June 30,  2004 and before the
first  anniversary  of the Closing  Date,  the Company shall make an offering of
such  Additional  Shares  to each  Investor  in  accordance  with the  following
provisions:

          (i) The Company shall deliver a notice (the "ISSUANCE NOTICE") to each
          Investor  stating (A) its bona fide intention to offer such Additional
          Shares,  (B) the number of such Additional  Shares to be offered,  (C)
          the price and  terms,  if any,  upon which it  proposes  to offer such
          Additional Shares, and (D) the anticipated closing date of the sale of
          such Additional Shares.

          (ii) By written  notification  received  by the  Company,  within five
          trading  days  after  giving of the  Issuance  Notice  (the  "RESPONSE
          PERIOD"),  any Investor may elect to purchase or obtain,  at the price
          and on the terms specified in the Issuance Notice,  up to its Pro Rata
          Amount (as defined  below) of such  Additional  Shares.  The "PRO RATA
          AMOUNT"  for any  given  Investor  shall  equal  that  portion  of the
          Additional  Securities  the  price  of  which  is  equal to 50% of the
          aggregate  purchase  price that such Investor paid to the Company upon
          the Closing under this Agreement,  and in such event the Company shall
          be obligated to sell such number of Additional Securities to each such
          Investor, even if the aggregate Pro Rata Amount for all such Investors
          exceeds the aggregate amount of Additional Securities that the Company
          had initially  proposed to offer. Any such purchase shall be completed
          at the same  closing as that of any third  party  purchasers  or at an
          additional closing thereunder.

          (iii)  The  Company  may,  during  the  75-day  period  following  the
          expiration of the Response  Period,  offer the remaining  unsubscribed
          portion  of  such  Additional  Shares  to any  person  or  persons  on
          substantially similar terms to those specified in the Issuance Notice.
          If the Company does not consummate the sale of such Additional  Shares
          within such period or if such  Additional  Shares are offered on terms
          not  substantially  similar to the terms of the offer specified in the
          Issuance  Notice,  the right provided  hereunder shall be deemed to be
          revived and such Additional Shares shall not be offered or sold unless
          first reoffered to the Investors in accordance herewith.

      (b)  The  participation  right  set  forth  in this  Section  9 may not be
assigned or  transferred,  except that such right is assignable by each Investor
to any  wholly-owned  subsidiary or parent of, or to any  corporation  or entity
that is, within the meaning of the Securities Act, controlling, controlled by or
under common control with,  any such  Investor,  provided in any event that such
assignee  is an  "accredited  investor"  as such term is defined in Rule  501(a)
promulgated under the Securities Act.

      (e)  AMENDMENTS  AND WAIVERS.  Any term of this  Agreement may be amended,
waived or  departed  from only with the  written  consent of the Company and the
holders of a majority of the Shares then held by  Investors.  Any  amendment  or
waiver effected in accordance with this Section 10(e) shall be binding upon each
party to this Agreement,  whether or not such party has signed such amendment or
waiver.  No such waiver or consent  shall be deemed to be or shall  constitute a
waiver  or  consent  with  respect  to any  other  terms or  provisions  of this
Agreement,  whether  or not  similar.  Each  such  waiver  or  consent  shall be
effective  only in the  specific  instance  and for the purpose for which it was
given,  and  shall not  constitute  a  continuing  waiver  or  consent.  No such
amendment  shall be  effective to the extent that it applies to less than all of
the Investors or their Shares, Warrants and Warrant Shares then outstanding.  No
consideration  shall be  offered  or paid to any person to amend or consent to a
waiver or  modification  of any provision of this  Agreement,  the  Registration
Rights Agreement or the Warrants unless the same  consideration  also is offered
to all the parties to this  Agreement or the  Registration  Rights  Agreement or
holders of the  Warrants,  as the case may be.  The  Company  shall give  prompt
written notice to an Investor of any amendment  hereof or waiver  hereunder that
was effected without the Investor's written consent.

      (f)  SUCCESSORS  AND  ASSIGNS.  This  Agreement is personal to each of the
parties  and may not be  assigned  without  the  written  consent  of the  other
parties;  provided,  however,  that any of the  Investors  shall be permitted to
assign this  Agreement to any person to whom it assigns or transfers  securities
issued or issuable  pursuant to this  Agreement in  compliance  with  applicable
securities  laws  and  this  Agreement.  Any  assignee  must  be an  "accredited
investor" as defined in Rule 501(a) promulgated under the Securities Act.

      (g)  SEVERABILITY.  In the event that any court of competent  jurisdiction
shall determine that any provision,  or any portion  thereof,  contained in this
Agreement shall be  unenforceable  in any respect,  then such provision shall be
deemed  limited to the extent  that such court deems it  enforceable,  and as so
limited  shall  remain in full  force and  effect.  In the event that such court
shall deem any such provision,  or portion thereof,  wholly  unenforceable,  the
remaining  provisions of this Agreement shall nevertheless  remain in full force
and effect.

      (h)  INTERPRETATION.  The parties hereto  acknowledge  and agree that: (i)
each party and such party's  counsel has reviewed  the terms and  provisions  of
this Agreement; (ii) the rule of construction to the effect that any ambiguities
are  resolved   against  the  drafting  party  shall  not  be  employed  in  the
interpretation  of this  Agreement;  and (iii) the terms and  provisions of this
Agreement shall be construed fairly as to the parties hereto and not in favor of
or against any party,  regardless of which party was generally  responsible  for

                                       15

the  preparation of this  Agreement.  Whenever used herein,  the singular number
shall include the plural, the plural shall include the singular,  the use of any
gender shall include all persons.

      (i)  HEADINGS  AND  CAPTIONS.  The  headings  and  captions of the various
subdivisions  of this Agreement are for  convenience of reference only and shall
in no way modify,  or affect the meaning or  construction of any of the terms or
provisions hereof.

      (j) NO WAIVER OF  RIGHTS,  POWERS AND  REMEDIES.  No failure or delay by a
party hereto in exercising any right, power or remedy under this Agreement,  and
no course of dealing  between the parties  hereto,  shall operate as a waiver of
any such right,  power or remedy of the party. No single or partial  exercise of
any right,  power or remedy  under this  Agreement  by a party  hereto,  nor any
abandonment  or  discontinuance  of steps to enforce  any such  right,  power or
remedy,  shall preclude such party from any other or further exercise thereof or
the exercise of any other right, power or remedy hereunder.  The election of any
remedy  by a party  hereto  shall not  constitute  a waiver of the right of such
party to pursue other available remedies.  No notice to or demand on a party not
expressly  required under this Agreement  shall entitle the party receiving such
notice or demand to any other or  further  notice or demand in  similar or other
circumstances  or  constitute  a waiver of the rights of the party  giving  such
notice or demand to any other or  further  action in any  circumstances  without
such notice or demand.

      (k) SURVIVAL OF REPRESENTATIONS  AND WARRANTIES.  All  representations and
warranties made by the parties hereto in this  Agreement,  shall survive (i) the
execution and delivery hereof,  (ii) any investigations  made by or on behalf of
the parties and (iii) the closing of the transaction contemplated hereby.

      (l)  EXPENSES.  Except as  otherwise  provided  in any  other  Transaction
Agreement,  the  Company and each  Investor  shall each be  responsible  for the
payment  of  and  bear  their  own  expenses  and  legal  fees  relating  to the
preparation and negotiation of the Transaction  Agreements and the  consummation
of the  Transactions,  provided,  however,  that in the event of the  successful
consummation of the  transactions  contemplated  by this Agreement,  the Company
shall pay the  reasonable  legal  fees and  other  third-party  expenses,  up to
$45,000,  of SDS incurred with respect to the preparation and negotiation of the
Transaction Agreements and the consummation of the transactions hereunder.

      (m) COUNTERPARTS AND FACSIMILE DELIVERY. This Agreement may be executed in
counterparts,  each of  which  shall be  deemed  an  original,  but all of which
together  shall  constitute  one and the same  instrument.  Any  signature  page
delivered by facsimile or other electronic image  transmission  shall be binding
to the same extent as an original  signature  page, with regard to any agreement
subject to the terms  hereof or any  amendment  thereto.  Any party who delivers
such a signature  page agrees to later  deliver an original  counterpart  to any
party who requests it.

      (n) SECURITIES LAW COMPLIANCE.

          (i) SECURITIES ACT. The Company shall timely prepare and file with the
          Commission  the form of notice of the sale of  securities  pursuant to

                                       16
<PAGE>

          the  requirements of Regulation D regarding the sale of the Shares and
          Warrants under this Agreement.

          (ii) STATE SECURITIES LAW COMPLIANCE -- SALE. The Company shall timely
          prepare  and file such  applications,  consents  to service of process
          (but not  including  a general  consent  to service  of  process)  and
          similar  documents  and take such other steps and perform such further
          acts as shall be required by the state  securities law requirements of
          each jurisdiction where an Investor resides,  as indicated on Schedule
          1, with  respect  to the sale of the Shares  and  Warrants  under this
          Agreement.

          (iii) STATE  SECURITIES  LAW COMPLIANCE  --RESALE.  Beginning no later
          than June 30, 2004 and continuing  until (i) the purchasers  have sold
          all of their  Registrable  Securities  under a Registration  Statement
          pursuant  to  Section 8 or (ii) the  Common  Stock  becomes a "covered
          security" under Section 18(b)(1)(A) of the Securities Act, the Company
          shall maintain within either Moody's Industrial Manual or Standard and
          Poor's Standard  Corporation  Descriptions (or any successors to these
          manuals  which  are  similarly  qualified  as  "recognized  securities
          manuals" under state Blue Sky laws) an updated listing  containing (i)
          the names of the officers and directors of the Company, (ii) a balance
          sheet  of the  Company  as of a date  that  is at no time  older  than
          eighteen  months and (iii) a profit and loss  statement of the Company
          for  either  the  preceding  fiscal  year or the most  recent  year of
          operations. Capitalized terms used in this Section 10(n)(iii), but not
          otherwise defined in this Agreement,  shall have the meanings assigned
          in the Registration Rights Agreement.

      (o)  INDEPENDENT   NATURE  OF  INVESTORS'   OBLIGATIONS  AND  RIGHTS.  The
obligations  of each Investor under the  Transaction  Agreements are several and
not joint with the obligations of any other  Investor,  and no Investor shall be
responsible  in any way for the  performance  of the  obligations  of any  other
Investor  under  any  such  agreement.  Nothing  contained  in  any  Transaction
Agreement, and no action taken by any Investor pursuant thereto, shall be deemed
to constitute the Investors as a partnership, an association, a joint venture or
any other kind of entity,  or create a presumption that the Investors are in any
way  acting in concert or as a group  with  respect to such  obligations  or the
Transactions.  Each  Investor  shall be  entitled to  independently  protect and
enforce its rights, including without limitation,  the rights arising out of the
Transaction Agreements,  and it shall not be necessary for any other Investor to
be  joined as an  additional  party in any  proceeding  for such  purpose.  Each
Investor  represents  that it has been  represented  by its own  separate  legal
counsel in its review and negotiation of the Transaction Agreements. For reasons
of  administrative  convenience  only, the Investors  acknowledge and agree that
they and their  respective  counsel have chosen to communicate  with the Company
and its counsel  through  Wiggin,  but neither Wiggin nor the Company's  counsel
represent  any  of  the  Investors  in  this  transaction,  except  that  Wiggin
represents SDS.

case of the issuance of the Warrant Shares) duly  authorized,  and no additional
corporate or stockholder action is required for the approval thereof. The shares
issuable upon  exercise of the Warrants  (the  "WARRANT  SHARES") have been duly
reserved for issuance by the Company.  The Transaction  Agreements have been or,

or  necessary  in  order  to  make  the  statements  therein,  in  light  of the
circumstances under which they were made, not misleading. A correct and complete
copy of each of the SEC Documents for any period ending on or after December 31,
2002 (the  "RECENT  REPORTS")  is  currently  available  to the  Investor at the

balance  sheet and related  consolidated  statements  of income,  cash flows and
changes in stockholders'  equity (including the related notes) as of and for the

its business so as to comply with all laws,  rules and  regulations,  judgments,
decrees or orders of any court,  administrative agency,  commission,  regulatory
authority  or other  governmental  authority  or  instrumentality,  domestic  or
foreign,  applicable  to its  operations,  the  violation of which would cause a
Material Adverse Affect. There are no judgments or orders, injunctions, decrees,
stipulations or awards (whether rendered by a court or administrative  agency or
by  arbitration),  including  any such actions  relating to  affirmative  action
claims or claims of  discrimination,  against  the Company or against any of its
properties or businesses.

conducted its business  only in the ordinary  course and there has not occurred,

knowledge, (i) the Company does not have any material liabilities or obligations

the balance sheet of the Company as at December 31, 2003.

as of the Agreement Date, (i) there are no outstanding options, warrants, scrip,
rights to subscribe  for,  puts,  calls,  rights of first  refusal,  agreements,
understandings,   claims  or  other  commitments  or  rights  of  any  character
whatsoever relating to, or securities or rights convertible into or exchangeable

duly issued or obtained and are in full force and effect,  and the Company is in

for any fees or commissions.

      (l) SECURITIES LAWS. Neither the Company nor any agent acting on behalf of
the Company  has taken any action (or will take any  action,  in the case of the
Warrant  Shares) which might cause this  Agreement or the Shares or Warrants (or
the Warrant  Shares,  as the case may be) to violate the  Securities  Act or the
Exchange Act or any rules or regulations promulgated thereunder, as in effect on
the Closing Date. Assuming that all of the representations and warranties of the
Investor  set  forth in  Section 4 are true and  correct,  the  offer,  sale and
issuance  of the  Shares  and  Warrants  in  conformity  with the  terms of this
Agreement are (and,  assuming there is no material change in the securities laws
of the United States,  the issuance of the Warrant Shares in conformity with the
terms of the  Warrants  will be) exempt from the  registration  requirements  of
Section  5 of the  Securities  Act and from the  qualification  or  registration
requirements of applicable "blue sky" laws.

internal accounting controls sufficient,  in the judgment of the Company's board
of directors, to provide reasonable assurance that (i) transactions are executed
in  accordance  with  management's  general  or  specific  authorizations,  (ii)
transactions  are  recorded as  necessary  to permit  preparation  of  financial
statements in conformity with generally  accepted  accounting  principles and to
maintain  asset  accountability,  (iii)  access to assets is  permitted  only in
accordance  with  management's  general or specific  authorization  and (iv) the

      (o) NO INVESTMENT  COMPANY.  The Company is not, and upon the issuance and
sale of the Shares and Warrants as  contemplated  by this Agreement will not be,

Sarbanes-Oxley Act, and the rules and regulations promulgated  thereunder,  upon
the effectiveness of such provisions.

      (q) INDEPENDENT NATURE OF THE INVESTOR.  The Company acknowledges that the
obligations of the Investor under the Transaction Agreements are several and not
joint with the obligations of any other third party  purchasers of the Company's
securities,  and  the  Investor  shall  not be  responsible  in any  way for the
performance  of the  obligations  of any other  third  party  purchasers  of the
Company's  securities.   Each  of  the  Investor  and  the  Company  agrees  and
acknowledges  that (i) the  decision of the  Investor to purchase the Shares and
the Warrants  pursuant to this  Agreement has been made (and the decision of the
Investor to purchase  the  Warrant  Shares  pursuant to the terms of the Warrant
will be made) by the Investor  independently of any other third party purchasers
of the  Company's  securities  and (ii) no other third party  purchasers  of the
Company's securities have acted as agent for the Investor in connection with the
Investor  making its  investment  hereunder  and that no such other  third party
purchasers will be acting as agent of the Investor in connection with monitoring
its investment  hereunder.  Nothing contained herein or in any other Transaction
Agreement  or any  agreement  of any such other  third party  purchaser,  and no
action taken by the Investor  pursuant hereto or any other third party purchaser
pursuant  thereto,  shall be deemed to constitute the Investor or any such other

                                       7
<PAGE>

third party purchasers as a partnership,  an association, a joint venture or any
other kind of entity,  or create a  presumption  that the  Investor  or any such
other third party purchasers are in any way acting in concert or as a group with
respect to any matters. The Investor shall be entitled to independently  protect
and enforce its rights, including without limitation,  the rights arising out of
this Agreement or out of any of the other Transaction  Agreements,  and it shall
not be necessary  for any such other third party  purchasers  to be joined as an
additional party in any proceeding for such purpose. To the extent that any such
other third party  purchasers  purchase  the same or similar  securities  as the
Investor hereunder or on the same or similar terms and conditions or pursuant to
the same or similar documents, all such matters are solely in the control of the
Company,  not the action or decision of the  Investor  and are not done with the
knowledge of the Investor hereunder,  and would be solely for the convenience of
the  Company  and not  because  it was  required  or  requested  to do so by the
Investor or any such other third party purchaser.

4.  REPRESENTATIONS  AND  WARRANTIES  OF  THE  INVESTOR.   The  Investor  hereby
represents and warrants to the Company as follows:

      (a) EXEMPT  TRANSACTION;  UNREGISTERED  SHARES AND WARRANTS.  The Investor
understands  that the Shares and Warrants are being offered and sold in reliance
on one or more  exemptions from  registration  provided for under the Securities
Act, and that the Company's  reliance upon such  exemptions  is  predicated,  in
part,  upon the  Investor's  representations  and  warranties  set forth in this
Agreement.  The  Investor  acknowledges  that it is  purchasing  the  Shares and
Warrants  without  being  offered  or  furnished  any  offering   literature  or
prospectus.  The  Investor  understands  that  neither the  Commission,  nor any
governmental  agency charged with the  administration  of the securities laws of
any jurisdiction nor any other  governmental  agency has passed upon or reviewed
the merits or  qualifications  of, or recommended or approved the offer and sale
of the Shares and Warrants pursuant to the terms of this Agreement.

      (b) INVESTMENT INTENT; ACCREDITATION; AUTHORITY. The Investor is acquiring
the Shares and Warrants for investment  for the  Investor's own account,  not as
nominee  or  agent,  for  investment  and not with a view to,  or for  resale in
connection  with, any distribution or public offering thereof within the meaning
of the Securities Act;  provided,  however,  that by making the  representations
herein,  the Investor  reserves the right to dispose of the Shares,  Warrants or
Warrant Shares at any time in accordance with this Agreement or the Warrant,  as
applicable, and in accordance with or pursuant to a registration statement or an
exemption  from  registration  under the  Securities  Act.  The  Investor  is an
"accredited investor" within the meaning of the Securities Act. The Investor has
the full right,  power,  authority  and  capacity to enter into and perform this
Agreement,  the terms of this Agreement constitute valid and binding obligations
of the Investor  enforceable in accordance with their terms,  except as the same
may  be  limited  by  equitable   principles  and  by  bankruptcy,   insolvency,
moratorium,  and other laws of general application  affecting the enforcement of
creditors' rights.

      (c)  KNOWLEDGE  AND  EXPERIENCE.  The Investor (i) has such  knowledge and
experience in financial and business  matters as to be capable of evaluating the
merits  and risks of the  Investor's  prospective  investment  in the Shares and
Warrants;  (ii) has the  ability to bear the  economic  risks of the  Investor's

                                       8
<PAGE>

prospective investment; (iii) has been furnished with and has had access to such
information as the Investor has considered  necessary to make a determination as
to the  purchase  of the  Shares  and  Warrants  together  with such  additional
information as is necessary to verify the accuracy of the information  supplied;
and  (iv)  has  had  all  questions  which  have  been  asked  by  the  Investor
satisfactorily answered by the Company.

      (d) RESTRICTED  SECURITIES.  The Investor  understands that the Shares and
Warrants  are  "restricted  securities"  as such term is  defined in Rule 144 of
Regulation D promulgated  under the Securities Act ("RULE 144") and must be held
indefinitely  unless  they  are  subsequently   registered  or  qualified  under
applicable  state  and  federal  securities  laws  or  an  exemption  from  such
registration  or  qualification  is  available.  Except as  contemplated  by the
Registration Rights Agreement,  the Investor  understands that it may resell the
Shares and Warrant Shares  pursuant to Rule 144 only after the  satisfaction  of
certain  requirements,  including the  requirement  that the Shares and Warrants
Shares be held for at least one year prior to resale.

      (e) NO  OBLIGATION  TO REGISTER.  The Investor  further  acknowledges  and
understands that, except as provided in the Registration  Rights Agreement,  the
Company is under no  obligation  to  register  the  Shares,  Warrants or Warrant
Shares.  The Investor  understands  that the certificate  evidencing the Shares,
Warrants and Warrant Shares will be imprinted with a legend which  prohibits the
transfer of the Shares,  Warrants and Warrant  Shares unless they are registered
or such  registration  is not  required  in the  opinion  of counsel in form and
substance satisfactory to the Company.

      (f) FOREIGN INVESTOR  REPRESENTATION.  The Investor is not a "U.S. person"
(as such term is defined in Rule 902(k) of  Regulation S  promulgated  under the
Securities Act), and the Investor hereby represents that it has satisfied itself
as to the full observance of the laws of its jurisdiction in connection with any
invitation  to  subscribe  for  the  Shares  and  Warrants  or any  use of  this
Agreement,  including (i) the legal requirements within its jurisdiction for the
purchase  of the Shares and  Warrants,  (ii) any foreign  exchange  restrictions
applicable to such purchase,  (iii) any  governmental or other consents that may
need to be obtained, and (iv) the income tax and other tax consequences, if any,
that may be relevant to the purchase,  holding,  redemption, sale or transfer of
the Shares and Warrants.  The Investor's  subscription  and payment for, and its
continued beneficial ownership of the Shares and Warrants,  will not violate any
applicable securities or other laws of its jurisdiction.

      (g)  DOMICILE.  The Investor is a Cayman  Islands  corporation  and has no
offices located in the United States.

      (h) NO NEED FOR LIQUIDITY.  The Investor's aggregate holding of securities
that are  "restricted  securities"  or otherwise  not readily  marketable is not
excessive in view of the  Investor's net worth and financial  circumstances  and
the purchase of the Shares and Warrants will not cause such commitment to become
excessive.

      (i) INDEPENDENT  ADVICE.  The Investor  understands that the Company urges
the Investor to seek independent  advice from professional  advisors relating to
the  suitability for the Investor of an investment in the Company in view of the

                                       9
<PAGE>

Investor's   overall   financial  needs  and  with  respect  to  legal  and  tax
implications of such an investment.

5.  RELIANCE.  The  Investor  understands  that  the  Company  may  rely  on the
representations and warranties in Section 4 in determining whether to permit the
Investor  to  purchase  the  Shares  and   Warrants.   If  for  any  reason  any
representations  and  warranties  are no longer true and  accurate  prior to the
Closing Date,  the Investor will give the Company  prompt  written notice of the
inaccuracy. By signing below, the Investor represents that the Investor has read
and confirmed  the truth and accuracy of each of the  foregoing  representations
and warranties.

6. ADDITIONAL COVENANTS OF THE PARTIES.

      (a)  INDEMNIFICATION.  Each  party  (an  "indemnifying  party")  agrees to
indemnify  and hold  harmless the other party hereto and each of its  directors,
officers,  members,  managers,  agents and affiliates (as  applicable)  from and
against any and all loss,  damage or liability due to or arising out of a breach
by such indemnifying party of any representation, warranty or covenant contained
in this  Agreement  and made by such  indemnifying  party.  The liability of the
Investor to provide indemnification  pursuant to this Section 6 shall be limited
in the aggregate to $375,000.

      (b) PLEDGE OF  SECURITIES.  The Company  acknowledges  and agrees that the
Shares, Warrants and Warrant Shares may be pledged by the Investor in connection
with a bona fide margin agreement or other loan or financing arrangement that is
secured by the Shares  Warrants  or Warrant  Shares.  The pledge of the  Shares,
Warrants  or  Warrant  Shares  shall  not be deemed  to be a  transfer,  sale or
assignment of the Shares, Warrants or Warrant Shares hereunder, and the Investor
shall not be  required  to  provide  the  Company  with any  notice  thereof  or
otherwise  make any  delivery to the Company  pursuant to this  Agreement or any
other  Transaction  Agreement.  The Company hereby agrees to execute and deliver
such  documentation  as a pledgee of the Shares,  Warrants or Warrant Shares may
reasonably request in connection with a pledge of the thereof to such pledgee by
the Investor.

transactions  contemplated hereby. Except as provided in the preceding sentence,
neither  the  Company  nor the  Investor  shall make any press  release or other
publicity  about the terms of this  Agreement or the  transactions  contemplated
hereby without the prior approval of the other unless otherwise required by law,
regulation or the rules of the Commission.  In addition, the Company agrees that
it shall not  disclose,  and shall not  include  in any  public  filing or other
announcement, the name of the Investor, unless expressly agreed to in writing by
the Investor or unless and until such  disclosure is, in the reasonable  opinion
of counsel to the Company,  required by law or applicable  regulation,  and then
only to the extent of such requirement.

      (d) LISTING.  The Company shall promptly  secure the listing of the Shares
and  Warrant  Shares  (and  any  Registrable   Securities  (as  defined  in  the

maintain the listing and trading of its Common Stock on the Nasdaq SmallCap, the
Nasdaq  National  Market,  the New York Stock  Exchange,  or the American  Stock
Exchange and will comply in all respects  with the Company's  reporting,  filing
and other  obligations  under the bylaws or rules of any  exchanges or automated

7. RESTRICTIVE LEGENDS AND STOP-TRANSFER ORDERS.

      (a) LEGEND.  The  instruments  representing  the Shares,  Warrants and, if
applicable, Warrant Shares shall bear the following legend or similar legend (as
well as any legends  required by applicable  corporate law and state and federal
securities laws):

          UNDER THE  SECURITIES  ACT OF 1933 (THE "ACT") AND MAY NOT
          BE  OFFERED,  SOLD OR  OTHERWISE  TRANSFERRED,  PLEDGED OR
          HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR,
          IN  THE   OPINION  OF   COUNSEL  IN  FORM  AND   SUBSTANCE
          SATISFACTORY  TO THE  ISSUER  OF  THESE  SECURITIES,  SUCH
          OFFER,  SALE OR TRANSFER,  PLEDGE OR  HYPOTHECATION  IS IN
          COMPLIANCE THEREWITH.

      (b) REMOVAL OF LEGEND AND  TRANSFER  RESTRICTIONS.  Any legend
endorsed  on a  certificate  pursuant  to this  Section  7 shall  be
removed,  and the Company  shall issue a  certificate  without  such

Warrant  Shares,  reasonably  satisfactory  to the  Company,  to the
effect that a sale, transfer or assignment of such Shares,  Warrants
or Warrant Shares may be made without registration.

8. PRICE  PROTECTION.  If the Company  issues or sells any shares of
its Common Stock or Common Stock  Equivalents,  other than  Excluded
Shares (as that term is defined below) ("ADDITIONAL  SHARES") at any
time  after  the  Closing  Date  and  prior to June  30,  2004  (the
"ADJUSTMENT  PERIOD") for a consideration  per share (as to any such
issuance,  the  "DILUTIVE  PRICE") (a) less than the Share Price (as
adjusted for stock splits,  stock dividends and the like) and (b) if

                                 11
<PAGE>

Additional  Shares have been previously issued during the Adjustment
Period with  respect to which the Company  has fully  complied  with
this  Section 8, then also less than the lowest  Dilutive  Price (as
adjusted for stock  splits,  stock  dividends and the like) at which
such  Additional  Shares  have been  previously  issued  during  the
Adjustment  Period,  then the Company will issue to each  Investor a
number of shares,  if  positive,  of Common  Stock to such  Investor
determined by the following formula:

                               X  =     (A * B / C) -  (A + D)

                  Where:       X  =     the number of shares of Common  Stock to
                                        be issued to the  Investor,  rounded  to
                                        the nearest whole number;

                                A  =    the  number of Shares (as  adjusted  for
                                        stock  splits,  stock  dividends and the
                                        like) then held by the Investor;

                                B  =    the Share Price (as  adjusted  for stock
                                        splits, stock dividends and the like);

                                C  =    the applicable Dilutive Price; and

                                D  =    the aggregate number of shares of Common
                                        Stock (as  adjusted  for  stock  splits,
                                        stock  dividends and the like) issued to
                                        the Investor  pursuant to this Section 8
                                        prior to the date of such determination.

For purposes of this Agreement,  the term "EXCLUDED SHARES" means: (i) shares of
Common Stock  issuable or issued after the Closing Date to officers,  employees,
consultants  or  directors  of the  Company  directly  or  pursuant  to a  stock
purchase,  stock option,  restricted stock or other written compensation plan or
agreement approved by the Board of Directors of the Company (the "BOARD");  (ii)
shares of Common Stock issued or issuable after the Closing Date,  primarily for
non-equity  financing  purposes  and as  approved  by the  Board,  to  financial
institutions  or lessors in  connection  with  commercial  credit  arrangements,
equipment  financings or similar transactions or to vendors of goods or services
or  customers;  (iii)  shares of Common  Stock  issuable  upon (a)  exercise  of
warrants,  options,  notes or other rights to acquire securities of the Company,
in each case, outstanding on the Agreement Date, (b) conversion of shares of the
Company's  Preferred  Stock,  par  value  $0.01  per  share  outstanding  on the

above.

                                       12
<PAGE>

If the Company shall issue or sell any warrants or other rights to subscribe for
or purchase any additional shares of Common Stock or any securities  convertible
into shares of Common Stock  (collectively,  "COMMON STOCK EQUIVALENTS")  during
the  Adjustment  Period,  whether  or not the  rights  to  exchange  or  convert
thereunder are  immediately  exercisable,  and the effective price per share for
which Common Stock is issuable upon the exercise, exchange or conversion of such
Common Stock Equivalents shall be less than (i) the Share Price (as adjusted for
stock splits,  stock dividends and the like) and (ii) if Additional  Shares have
been  previously  issued during the Adjustment  Period with respect to which the
Company has fully  complied  with this Section 8, then also less than the lowest
Dilutive Price (as adjusted for stock splits,  stock  dividends and the like) at
which such Additional  Shares have been previously  issued during the Adjustment
Period,  then the Company  shall issue to the Investor  that number of shares of
Common Stock that would be issuable pursuant to this Section 8 on the basis that
the maximum number of additional shares of Common Stock issuable pursuant to all
such  Common  Stock  Equivalents  shall  be  deemed  to  have  been  issued  and
outstanding and the Company shall have received all of the consideration payable
therefor,  if any, as of the date of the actual  issuance  of such Common  Stock
Equivalents.  No further  issuances  shall be made under this Section 8 upon the
actual issue of such Common Stock upon the  exercise,  conversion or exchange of
such  Common  Stock  Equivalents,  unless  such  actual  issue is at a per share
consideration  lower than the  Dilutive  Price used for  purposes of the initial
adjustment pursuant to this Section 8.

      (e)  AMENDMENTS  AND WAIVERS.  Any term of this  Agreement may be amended,
waived or  departed  from only with the  written  consent of the Company and the
Investor.  No such waiver or consent shall be deemed to be or shall constitute a
waiver  or  consent  with  respect  to any  other  terms or  provisions  of this
Agreement,  whether  or not  similar.  Each  such  waiver  or  consent  shall be
effective  only in the  specific  instance  and for the purpose for which it was
given, and shall not constitute a continuing waiver or consent.

      (f)  SUCCESSORS  AND  ASSIGNS.  This  Agreement is personal to each of the
parties and may not be assigned  without the written consent of the other party;
provided, however, that the Investor shall be permitted to assign this Agreement

                                       14
<PAGE>

to any person to whom it  assigns or  transfers  securities  issued or  issuable
pursuant to this Agreement in compliance  with  applicable  securities  laws and
this Agreement. Any assignee must be an "accredited investor" as defined in Rule
501(a) promulgated under the Securities Act.

      (g)  SEVERABILITY.  In the event that any court of competent  jurisdiction
shall determine that any provision,  or any portion  thereof,  contained in this
Agreement shall be  unenforceable  in any respect,  then such provision shall be
deemed  limited to the extent  that such court deems it  enforceable,  and as so
limited  shall  remain in full  force and  effect.  In the event that such court
shall deem any such provision,  or portion thereof,  wholly  unenforceable,  the
remaining  provisions of this Agreement shall nevertheless  remain in full force
and effect.

      (h)  INTERPRETATION.  The parties hereto  acknowledge  and agree that: (i)
each party and such party's  counsel has reviewed  the terms and  provisions  of
this Agreement; (ii) the rule of construction to the effect that any ambiguities
are  resolved   against  the  drafting  party  shall  not  be  employed  in  the
interpretation  of this  Agreement;  and (iii) the terms and  provisions of this
Agreement shall be construed fairly as to the parties hereto and not in favor of
or against any party,  regardless of which party was generally  responsible  for
the  preparation of this  Agreement.  Whenever used herein,  the singular number
shall include the plural, the plural shall include the singular,  the use of any
gender shall include all persons.

      (i)  HEADINGS  AND  CAPTIONS.  The  headings  and  captions of the various
subdivisions  of this Agreement are for  convenience of reference only and shall
in no way modify,  or affect the meaning or  construction of any of the terms or
provisions hereof.

      (j) NO WAIVER OF  RIGHTS,  POWERS AND  REMEDIES.  No failure or delay by a
party hereto in exercising any right, power or remedy under this Agreement,  and
no course of dealing  between the parties  hereto,  shall operate as a waiver of
any such right,  power or remedy of the party. No single or partial  exercise of
any right,  power or remedy  under this  Agreement  by a party  hereto,  nor any
abandonment  or  discontinuance  of steps to enforce  any such  right,  power or
remedy,  shall preclude such party from any other or further exercise thereof or
the exercise of any other right, power or remedy hereunder.  The election of any
remedy  by a party  hereto  shall not  constitute  a waiver of the right of such
party to pursue other available remedies.  No notice to or demand on a party not
expressly  required under this Agreement  shall entitle the party receiving such
notice or demand to any other or  further  notice or demand in  similar or other
circumstances  or  constitute  a waiver of the rights of the party  giving  such
notice or demand to any other or  further  action in any  circumstances  without
such notice or demand.

      (k) SURVIVAL OF REPRESENTATIONS  AND WARRANTIES.  All  representations and
warranties made by the parties hereto in this  Agreement,  shall survive (i) the
execution and delivery hereof,  (ii) any investigations  made by or on behalf of
the parties and (iii) the closing of the transaction contemplated hereby.

      (l)  EXPENSES.  Except as  otherwise  provided  in any  other  Transaction
Agreement,  the  Company  and the  Investor  shall each be  responsible  for the
payment  of  and  bear  their  own  expenses  and  legal  fees  relating  to the
preparation and negotiation of the Transaction  Agreements and the  consummation
of the Transactions.

      (m) COUNTERPARTS AND FACSIMILE DELIVERY. This Agreement may be executed in
counterparts,  each of  which  shall be  deemed  an  original,  but all of which
together  shall  constitute  one and the same  instrument.  Any  signature  page
delivered by facsimile or other electronic image  transmission  shall be binding
to the same extent as an original  signature  page, with regard to any agreement
subject to the terms  hereof or any  amendment  thereto.  Any party who delivers
such a signature  page agrees to later  deliver an original  counterpart  to any
party who requests it.

      (n) SECURITIES LAW COMPLIANCE.

          (i) SECURITIES ACT. The Company shall timely prepare and file with the
          Commission  the form of notice of the sale of  securities  pursuant to
          the  requirements of Regulation D regarding the sale of the Shares and
          Warrants under this Agreement.

          (ii) STATE SECURITIES LAW COMPLIANCE -- SALE. The Company shall timely
          prepare  and file such  applications,  consents  to service of process
          (but not  including  a general  consent  to service  of  process)  and
          similar  documents  and take such other steps and perform such further
          acts as shall be required by the State of  Illinois,  with  respect to
          the sale of the Shares and Warrants under this Agreement.

          (iii) STATE  SECURITIES  LAW COMPLIANCE  --RESALE.  Beginning no later
          than June 30, 2004 and continuing  until (i) the Investor has sold all
          of its Registrable  Securities under a Registration  Statement or (ii)
          the  Common  Stock   becomes  a  "covered   security"   under  Section
          18(b)(1)(A) of the Securities  Act, the Company shall maintain  within
          either  Moody's  Industrial  Manual or  Standard  and Poor's  Standard
          Corporation Descriptions (or any successors to these manuals which are
          similarly  qualified as  "recognized  securities  manuals" under state
          Blue Sky  laws) an  updated  listing  containing  (i) the names of the
          officers and  directors of the  Company,  (ii) a balance  sheet of the
          Company as of a date that is at no time older than eighteen months and
          (iii) a profit  and loss  statement  of the  Company  for  either  the
          preceding   fiscal  year  or  the  most  recent  year  of  operations.
          Capitalized terms used in this Section  10(n)(iii),  but not otherwise
          defined in this  Agreement,  shall have the  meanings  assigned in the
          Registration Rights Agreement.

      (o)  INDEPENDENT  NATURE OF THE  INVESTOR'S  OBLIGATIONS  AND RIGHTS.  The
obligations of the Investor under the Transaction Agreements are several and not
joint with the  obligations of any other third party  purchaser of the Company's
securities,  and  the  Investor  shall  not be  responsible  in any  way for the
performance of the obligations of any other third party  purchaser.  Each of the
Investor and the Company  agrees and  acknowledges  that (i) the decision of the
Investor to purchase  securities pursuant to this Agreement has been made by the
Investor  independently  of any other third party  purchasers  of the  Company's
securities and (ii) no other third party purchasers of the Company's  securities
have acted as agent for the Investor in connection  with the Investor making its
investment  hereunder  and that no such other  third  party  purchasers  will be

                                       16
<PAGE>

acting as agent of the Investor in connection  with  monitoring  its  investment
hereunder.  Nothing  contained  herein or in any  Transaction  Agreement  or any
agreement  of any such other third party  purchaser,  and no action taken by the
Investor  pursuant hereto or any other third party purchaser  pursuant  thereto,
shall be deemed to constitute  the Investor or any other third party  purchasers
as a partnership,  an association,  a joint venture or any other kind of entity,
or create a  presumption  that the Investor and any other third party  purchaser
are in any way acting in concert or as a group with respect to any matters.  The
Investor  shall be  entitled  to  independently  protect and enforce its rights,
including  without  limitation,  the  rights  arising  out  of  the  Transaction
Agreements, and it shall not be necessary for any other third party purchaser to
be joined as an additional  party in any  proceeding  for such  purpose.  To the
extent that any such other third party  purchasers  purchase the same or similar
securities  as the  Investor  hereunder  or on the  same or  similar  terms  and
conditions  or pursuant to the same or similar  documents,  all such matters are
solely in the control of the Company, not the action or decision of the Investor
and are not done with the  knowledge  of the  Investor  hereunder,  and would be
solely for the  convenience  of the Company  and not because it was  required or
requested to do so by the Investor or any such other third party purchaser.

                            [Signature page follows.]
