than  thirty  (30) days after the  Closing  Date (the  "Filing  Deadline"),  the
Company shall prepare and file with the SEC one  Registration  Statement on Form

registration  statement as is then available to effect a registration for resale

covering the resale of the Registrable Securities in an amount at least equal to

such  indeterminate  number of additional  shares of Common Stock resulting from
stock  splits,  stock  dividends  or similar  transactions  with  respect to the
Registrable  Securities.  The Company shall use its  reasonable  best efforts to
obtain from each person who now has  piggyback  registration  rights a waiver of
those  rights  with  respect to the  Registration  Statement.  The  Registration
Statement  (and each  amendment  or  supplement  thereto,  and each  request for
acceleration  of  effectiveness  thereof)  shall be provided in accordance  with
Section 3(c) to the  Investors  and their  counsel  prior to its filing or other
submission.  If a Registration  Statement covering the Registrable Securities is
not filed with the SEC on or prior to the Filing Deadline, the Company will make
pro rata payments to each Investor,  as liquidated damages and not as a penalty,
in an amount equal to 2.0% of the aggregate amount invested by such Investor for
each 30-day  period or pro rata for any  portion  thereof  following  the Filing
Deadline  for which no  Registration  Statement  is filed  with  respect  to the

Investors,  and shall not constitute the  Investors'  exclusive  remedy for such
events.  Such  payments  shall be made to each  Investor  in cash or  additional
shares  of Common  Stock,  as  determined  by each  Investor,  and shall be paid
monthly  within  three  (3)  Business  Days  after  the last  day of each  month
following the Filing Deadline.

          (ii) Additional Registrable Securities. Upon the written demand of any
Investor and upon any change in the  Exercise  Price (as defined in the Warrants
and the Placement Agent Warrants,  respectively)  such that additional shares of
Common Stock become issuable upon the exercise of the Warrants and/or  Placement
Agent  Warrants,  the  Company  shall  prepare and file with the SEC one or more
Registration  Statements on Form S-3 or amend the  Registration  Statement filed
pursuant to clause (i) above, if such Registration  Statement has not previously
been declared  effective  (or, if Form S-3 is not then available to the Company,
on  such  form of  registration  statement  as is then  available  to  effect  a
registration  for  resale  of  such  additional  shares  of  Common  Stock  (the
"Additional  Shares"),  subject to the Required Investors' consent) covering the
resale of the Additional  Shares,  but only to the extent the Additional  Shares
are  not at the  time  covered  by an  effective  Registration  Statement.  Such
Registration  Statement also shall cover, to the extent allowable under the 1933
Act  and  the  rules   promulgated   thereunder   (including   Rule  416),  such
indeterminate  number of additional  shares of Common Stock resulting from stock
splits,  stock dividends or similar  transactions with respect to the Additional
Shares.  The Company shall use its  reasonable  best efforts to obtain from each
person who now has piggyback  registration  rights a waiver of those rights with
respect to such  Registration  Statement.  The Registration  Statement (and each
amendment  or  supplement   thereto,   and  each  request  for  acceleration  of
effectiveness  thereof) shall be provided in accordance with Section 3(c) to the
Investors  and  their  counsel  prior to its  filing or other  submission.  If a
Registration  Statement  covering the Additional  Shares is required to be filed


under  this  Section  2(a)(ii)  and is not filed  with the SEC  within  five (5)
Business Days after the request of any Investor or the  occurrence of any of the
events specified in this Section 2(a)(ii) (the  "Additional  Shares  Deadline"),
the Company will make pro rata payments to each Investor,  as liquidated damages
and not as a  penalty,  in an  amount  equal  to 2.0%  of the  aggregate  amount
invested by such  Investor  for each  30-day  period or pro rata for any portion
thereof following the date by which such Registration Statement should have been
filed  for  which  no  Registration  Statement  is  filed  with  respect  to the
Additional  Shares.  Such  payments  shall  be in  partial  compensation  to the
Investors,  and shall not constitute the  Investors'  exclusive  remedy for such
events.  Such  payments  shall be made to each  Investor  in cash or  additional
shares  of Common  Stock,  as  determined  by each  Investor,  and shall be paid
monthly  within  three  (3)  Business  Days  after  the last  day of each  month
following the Additional Shares Deadline.

          (iii) S-3  Qualification.  If the  Company  is not  eligible  to use a
registration  statement on Form S-3 as provided in Sections 2(a)(i) and 2(a)(ii)
above, then, promptly following the date (the  "Qualification  Date") upon which
the Company  becomes  eligible to use a  registration  statement  on Form S-3 to
register the Registrable  Securities or Additional  Shares,  as applicable,  for
resale,  but in no event  more than ten (10) days after the  Qualification  Date
(the "Qualification  Deadline"), the Company shall file a registration statement
on Form S-3  covering  the  Registrable  Securities  or  Additional  Shares,  as
applicable  (or a  post-effective  amendment  on  Form  S-3 to the  registration
statement  on  Form  S-1) (a  "Shelf  Registration  Statement")  and  shall  use
commercially reasonable efforts to cause such Shelf Registration Statement to be
declared   effective  as  promptly  as  practicable   thereafter.   If  a  Shelf
Registration Statement covering the Registrable Securities is not filed with the
SEC on or prior to the  Qualification  Deadline,  the Company will make pro rata
payments to each  Investor,  as liquidated  damages and not as a penalty,  in an
amount equal to 2.0% of the aggregate  amount invested by such Investor for each
30-day  period or pro rata for any portion  thereof  following the date by which
such Shelf Registration Statement should have been filed for which no such Shelf
Registration  Statement is filed with respect to the  Registrable  Securities or
Additional Shares, as applicable. Such payments shall be in partial compensation
to the Investors,  and shall not constitute the Investors'  exclusive remedy for
such events.  Such payments shall be made to each Investor in cash or additional
shares  of Common  Stock,  as  determined  by each  Investor,  and shall be paid
monthly  within  three  (3)  Business  Days  after  the last  day of each  month
following the Qualification Deadline.

          (b) Expenses.  The Company will pay all expenses  associated with each
registration,  including  filing and printing  fees,  the Company's  counsel and
accounting  fees and expenses,  costs  associated  with clearing the Registrable
Securities for sale under applicable  state  securities laws,  listing fees, and
fees and expenses of one counsel to the Investors (not to exceed $7,500).  Other
than the above, the Investors shall bear their respective expenses in connection
with the registration,  including, without limitation,  discounts,  commissions,
fees of  underwriters,  selling brokers,  dealer managers or similar  securities
industry professionals with respect to the Registrable Securities being sold.


          (c) Effectiveness.

          (i) The Company shall use commercially  reasonable efforts to have the
Registration  Statement declared  effective as soon as practicable.  The Company
shall notify the  Investors  by facsimile or e-mail as promptly as  practicable,
and  in any  event,  within  twenty-four  (24)  hours,  after  any  Registration
Statement is declared effective and shall  simultaneously  provide the Investors
with copies of any related  Prospectus to be used in connection with the sale or
other  disposition of the securities  covered thereby.  If (A)(x) a Registration
Statement  covering the Registrable  Securities is not declared effective by the
SEC  prior to the  earlier  of (i)  five (5)  Business  Days  after  the SEC has
notified the Company that no review of the  Registration  Statement will be made
or (ii)  within  ninety  (90) days after the Closing  Date,  (y) a  Registration
Statement covering Additional Shares is not declared effective by the SEC within
ninety  (90)  days  after  the  Additional   Shares  Deadline  or  (z)  a  Shelf
Registration  Statement is not declared  effective by the SEC within ninety (90)
days after the Qualification Deadline, or (B) after a Registration Statement has
been  declared  effective  by the SEC,  sales  cannot be made  pursuant  to such
Registration Statement for any reason (including without limitation by reason of
a stop order, or the Company's  failure to update the  Registration  Statement),
but excluding the inability of any Investor to sell the  Registrable  Securities
covered  thereby  due to market  conditions  and except as excused  pursuant  to
subparagraph  (ii) below,  then the Company will make pro rata  payments to each
Investor, as liquidated damages and not as a penalty, in an amount equal to 2.0%
of the aggregate  amount invested by such Investor for each 30-day period or pro
rata for any  portion  thereof  following  the date by which  such  Registration
Statement  should have been  effective (the  "Blackout  Period").  Such payments
shall be in partial compensation to the Investors,  and shall not constitute the
Investors'  exclusive remedy for such events.  The amounts payable as liquidated
damages  pursuant  to this  paragraph  shall be paid  monthly  within  three (3)
Business Days after the last day of each month following the commencement of the
Blackout  Period until the  termination  of the Blackout  Period.  Such payments
shall be made to each Investor in cash or in  additional  shares of Common Stock
as determined by each Investor.

          (ii) For not more than twenty (20)  consecutive days or for a total of
not more than forty-five (45) days in any twelve (12) month period,  the Company
may delay the  disclosure  of material  non-public  information  concerning  the
Company,  by suspending the use of any Prospectus  included in any  registration
contemplated  by this Section  containing  such  information,  the disclosure of
which at the time is not, in the good faith opinion of the Company,  in the best
interests of the Company (an "Allowed Delay");  provided, that the Company shall
promptly  (a) notify the  Investors  and the  Placement  Agent in writing of the
existence of (but in no event,  without the prior written consent of an Investor
and the Placement Agent,  shall the Company disclose to such Investor any of the
facts or circumstances regarding) material non-public information giving rise to
an Allowed Delay, (b) advise the Investors and the Placement Agent in writing to
cease all sales under the  Registration  Statement  until the end of the Allowed
Delay and (c) use commercially  reasonable efforts to terminate an Allowed Delay
as promptly as practicable.

     3.  Company  Obligations.  The  Company  will use  commercially  reasonable
efforts to effect the  registration of the Registrable  Securities in accordance
with the terms hereof,  and pursuant  thereto the Company will, as expeditiously
as possible:

          (a) use  commercially  reasonable  efforts to cause such  Registration
Statement to become effective and to remain continuously  effective for a period
that will  terminate  upon the earlier of (i) the date on which all  Registrable
Securities covered by such Registration  Statement as amended from time to time,
have been sold, and (ii) the date on which all Registrable Securities covered by


such   Registration   Statement  may  be  sold  pursuant  to  Rule  144(k)  (the

Effectiveness Period has expired;

          (b) prepare and file with the SEC such  amendments and  post-effective

respect  to  the  distribution  of all of  the  Registrable  Securities  covered
thereby;

          (c) provide copies to and permit  counsel  designated by the Investors

          (d)  furnish to the  Investors  and their legal  counsel (i)  promptly
after the same is  prepared  and  publicly  distributed,  filed with the SEC, or

filing date,  receipt date or sending  date, as the case may be) one (1) copy of
any  Registration   Statement  and  any  amendment  thereto,   each  preliminary
prospectus and Prospectus  and each  amendment or supplement  thereto,  and each
letter  written  by or on behalf of the  Company  to the SEC or the staff of the
SEC,  and each item of  correspondence  from the SEC or the staff of the SEC, in
each case relating to such Registration Statement (other than any portion of any
thereof which contains information for which the Company has sought confidential
treatment),  and (ii)  such  number  of  copies  of a  Prospectus,  including  a
preliminary  prospectus,  and all  amendments and  supplements  thereto and such
other  documents as each Investor may reasonably  request in order to facilitate
the  disposition of the Registrable  Securities  owned by such Investor that are
covered by the related Registration Statement;

          (e) use commercially reasonable efforts to (i) prevent the issuance of
any stop order or other suspension of  effectiveness  and, (ii) if such order is

          (f)  prior to any  public  offering  of  Registrable  Securities,  use
commercially  reasonable  efforts to register or qualify or  cooperate  with the
Investors and their counsel in connection with the registration or qualification
of such  Registrable  Securities for offer and sale under the securities or blue
sky laws of such  jurisdictions  requested by the  Investors  and do any and all
other  commercially  reasonable acts or things  necessary or advisable to enable
the distribution in such jurisdictions of the Registrable  Securities covered by

exchange,  interdealer  quotation  system  or  other  market  on  which  similar
securities issued by the Company are then listed;


          (h)  immediately  notify the Investors,  at any time when a Prospectus
relating to  Registrable  Securities is required to be delivered  under the 1933
Act,  upon  discovery  that,  or upon the  happening of any event as a result of
which, the Prospectus included in a Registration  Statement,  as then in effect,
includes an untrue  statement of a material  fact or omits to state any material
fact required to be stated therein or necessary to make the  statements  therein
not misleading in light of the circumstances  then existing,  and at the request
of any such  holder,  promptly  prepare and furnish to such holder a  reasonable
number of copies of a supplement to or an amendment of such Prospectus as may be
necessary so that, as thereafter delivered to the purchasers of such Registrable
Securities,  such Prospectus shall not include an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein not misleading in light of the circumstances then
existing; and

          (i) otherwise use commercially  reasonable  efforts to comply with all

that may at any time permit the  Investors to sell shares of Common Stock to the
public without  registration,  the Company covenants and agrees to: (i) make and
keep public information available,  as those terms are understood and defined in
Rule 144,  until the  earlier  of (A) six  months  after such date as all of the
Registrable  Securities may be resold  pursuant to Rule 144(k) or any other rule
of similar effect or (B) such date as all of the  Registrable  Securities  shall
have been  resold;  (ii) file with the SEC in a timely  manner all  reports  and
other documents required of the Company under the 1934 Act; and (iii) furnish to

documents and  properties of the Company as may be reasonably  necessary for the
purpose  of such  review,  and  cause  the  Company's  officers,  directors  and

diligence  with  respect to the  Company and the  accuracy of such  Registration
Statement.

          The Company shall not disclose material  nonpublic  information to the
Investors,  or to advisors to or representatives of the Investors,  unless prior
to disclosure of such  information the Company  identifies  such  information as
being material nonpublic  information and provides the Investors,  such advisors
and  representatives  with the  opportunity  to accept or refuse to accept  such
material  nonpublic  information  for review and any Investor  wishing to obtain

to  have  any  of  the  Registrable  Securities  included  in  the  Registration
Statement.

agrees to cooperate  with the Company as reasonably  requested by the Company in
connection  with  the  preparation  and  filing  of  a  Registration   Statement

election to exclude all of its  Registrable  Securities  from such  Registration
Statement.

          (c) Each  Investor  agrees  that,  upon receipt of any notice from the
Company of either (i) the  commencement  of an Allowed Delay pursuant to Section
2(c)(ii) or (ii) the happening of an event pursuant to Section 3(h) hereof, such

pursuant to the Registration  Statement  covering such  Registrable  Securities,
until the  Investor's  receipt  of the  copies of the  supplemented  or  amended
prospectus filed with the SEC and until any related post-effective  amendment is
declared  effective  and, if so  directed by the  Company,  the  Investor  shall
deliver to the Company (at the expense of the  Company) or destroy  (and deliver

possession of the Prospectus covering the Registrable  Securities current at the
time of receipt of such notice.

Investor within the meaning of the 1933 Act, against any losses, claims, damages
or  liabilities,  joint or several,  to which they may become  subject under the
1933 Act or otherwise,  insofar as such losses,  claims,  damages or liabilities
(or actions in respect  thereof)  arise out of or are based upon: (i) any untrue


statement or alleged  untrue  statement of any  material  fact  contained in any
Registration Statement, any preliminary prospectus or final prospectus contained
therein, or any amendment or supplement  thereof;  (ii) any blue sky application
or other document executed by the Company specifically for that purpose or based
upon written  information  furnished by the Company  filed in any state or other
jurisdiction in order to qualify any or all of the Registrable  Securities under
the  securities  laws thereof  (any such  application,  document or  information
herein called a "Blue Sky Application");  (iii) the omission or alleged omission
to state therein a material  fact required to be stated  therein or necessary to
make the statements therein not misleading; (iv) any violation by the Company or
its agents of any rule or regulation  promulgated  under the 1933 Act applicable
to the Company or its agents and relating to action or inaction  required of the
Company in connection with such registration;  or (v) any failure to register or
qualify the  Registrable  Securities  included in any such  Registration  in any
state where the Company or its agents has affirmatively  undertaken or agreed in
writing that the Company will undertake such registration or qualification on an
Investor's  behalf and will  reimburse  such  Investor,  and each such  officer,
director  or member  and each  such  controlling  person  for any legal or other
expenses  reasonably  incurred  by  them in  connection  with  investigating  or
defending any such loss, claim, damage, liability or action; provided,  however,
that the  Company  will not be liable in any such case if and to the extent that
any such  loss,  claim,  damage or  liability  arises out of or is based upon an
untrue  statement or alleged untrue statement or omission or alleged omission so
made in  conformity  with  information  furnished  by such  Investor or any such
controlling  person  in  writing  specifically  for  use  in  such  Registration
Statement or Prospectus.

          (b) Indemnification by the Investors.  Each Investor agrees, severally
but not jointly, to indemnify and hold harmless, to the fullest extent permitted
by law, the Company, its directors,  officers, employees,  stockholders and each
person who controls the Company (within the meaning of the 1933 Act) against any
losses, claims, damages,  liabilities and expense (including reasonable attorney
fees) resulting from any untrue  statement of a material fact or any omission of
a  material  fact  required  to be  stated  in  the  Registration  Statement  or
Prospectus  or  preliminary  prospectus  or amendment or  supplement  thereto or
necessary to make the statements therein not misleading, to the extent, but only
to the extent  that such  untrue  statement  or  omission  is  contained  in any
information  furnished in writing by such  Investor to the Company  specifically
for  inclusion  in such  Registration  Statement or  Prospectus  or amendment or
supplement thereto. In no event shall the liability of an Investor be greater in
amount than the dollar  amount of the proceeds  (net of all expense paid by such
Investor in connection  with any claim relating to this Section 6 and the amount
of any damages such  Investor has  otherwise  been  required to pay by reason of
such untrue  statement or omission)  received by such  Investor upon the sale of
the Registrable Securities included in the Registration Statement giving rise to
such indemnification obligation.

          (c) Conduct of  Indemnification  Proceedings.  Any person  entitled to
indemnification hereunder shall (i) give prompt notice to the indemnifying party
of any claim with respect to which it seeks indemnification and (ii) permit such
indemnifying  party to assume the defense of such claim with counsel  reasonably
satisfactory to the  indemnified  party;  provided,  that any person entitled to
indemnification hereunder shall have the right to employ separate counsel and to
participate  in the  defense of such  claim,  but the fees and  expenses of such
counsel shall be at the expense of such person unless (a) the indemnifying party
has agreed to pay such fees or  expenses,  or (b) the  indemnifying  party shall
have  failed to assume the defense of such claim and employ  counsel  reasonably
satisfactory  to such  person  or (c) in the  reasonable  judgment  of any  such
person,  based upon written advice of its counsel, a conflict of interest exists
between such person and the  indemnifying  party with respect to such claims (in
which case, if the person notifies the  indemnifying  party in writing that such
person  elects to employ  separate  counsel at the  expense of the  indemnifying


party, the indemnifying  party shall not have the right to assume the defense of
such claim on behalf of such person); and provided, further, that the failure of
any  indemnified  party to give notice as provided  herein shall not relieve the
indemnifying party of its obligations hereunder,  except to the extent that such
failure to give notice shall materially  adversely affect the indemnifying party
in the  defense  of any such  claim or  litigation.  It is  understood  that the
indemnifying  party shall not, in  connection  with any  proceeding  in the same
jurisdiction,  be liable for fees or expenses of more than one separate  firm of
attorneys at any time for all such indemnified  parties.  No indemnifying  party
will, except with the consent of the indemnified party,  consent to entry of any
judgment or enter into any settlement that does not include as an  unconditional
term thereof the giving by the claimant or plaintiff to such  indemnified  party
of a release from all liability in respect of such claim or litigation.

          (d) Contribution.  If for any reason the indemnification  provided for
in the preceding  paragraphs (a) and (b) is unavailable to an indemnified  party
or insufficient to hold it harmless,  other than as expressly specified therein,
then the  indemnifying  party shall  contribute to the amount paid or payable by
the indemnified  party as a result of such loss,  claim,  damage or liability in
such  proportion  as is  appropriate  to  reflect  the  relative  fault  of  the
indemnified  party and the  indemnifying  party,  as well as any other  relevant
equitable  considerations.  No  person  guilty of  fraudulent  misrepresentation
within  the  meaning  of  Section  11(f) of the 1933 Act  shall be  entitled  to
contribution from any person not guilty of such fraudulent misrepresentation. In
no event shall the contribution obligation of a holder of Registrable Securities
be greater in amount than the dollar amount of the proceeds (net of all expenses
paid by such holder in connection  with any claim relating to this Section 6 and
the amount of any damages  such  holder has  otherwise  been  required to pay by
reason of such  untrue or  alleged  untrue  statement  or  omission  or  alleged
omission) received by it upon the sale of the Registrable Securities giving rise
to such contribution obligation.

                                  Title:  Director Corporate Finance

The Investors:  [Contained in Omnibus Signature Page in Subscription Agreement]


                                                                       Exhibit A

                              Plan of Distribution

     The selling stockholders (the "Selling Stockholders",  which as used herein
includes  donees,  pledgees,  transferees or other  successors-in-interest  of a
Selling  Stockholder  selling  shares of Common  Stock or interests in shares of
Common  Stock  received  after  the  date  of  this  prospectus  from a  Selling
Stockholder as a gift, pledge,  partnership distribution or other transfer) may,
from time to time,  sell,  transfer or otherwise  dispose of any or all of their
shares  of Common  Stock or  interests  in  shares of Common  Stock on any stock
exchange,  market or  trading  facility  on which the  shares  are  traded or in
private  transactions.  These dispositions may be at fixed prices, at prevailing
market prices at the time of sale, at prices  related to the  prevailing  market
price,  at  varying  prices  determined  at the time of sale,  or at  negotiated
prices.

     The Selling  Stockholders may use any one or more of the following  methods
when disposing of shares or interests therein:

     -  ordinary   brokerage   transactions   and   transactions  in  which  the
broker-dealer solicits purchasers;

     - block trades in which the  broker-dealer  will attempt to sell the shares
as agent,  but may  position  and resell a portion of the block as  principal to
facilitate the transaction;

     - purchases by a broker-dealer as principal and resale by the broker-dealer
for its account;

     - an exchange  distribution  in accordance with the rules of the applicable
exchange;

     - privately negotiated transactions;

     - short sales effected after the date the  registration  statement of which
this Prospectus is a part is declared effective by the SEC;

     -  through  the  writing  or   settlement   of  options  or  other  hedging
transactions, whether through an options exchange or otherwise;

     -  broker-dealers  may  agree  with  the  Selling  Stockholders  to  sell a
specified number of such shares at a stipulated price per share; and

     - a combination of any such methods of sale.

     The Selling Stockholders may, from time to time, pledge or grant a security
interest in some or all of the shares of Common Stock owned by them and, if they
default in the performance of their secured obligations, the pledgees or secured
parties may offer and sell the shares of Common Stock,  from time to time, under
this  Prospectus,  or under an amendment to this Prospectus under Rule 424(b)(3)
or other  applicable  provision  of the 1933 Act  amending  the list of  Selling
Stockholders to include the pledgee, transferee or other  successors-in-interest
as Selling Stockholders under this Prospectus. The Selling Stockholders also may
transfer  the shares of Common Stock in other  circumstances,  in which case the
transferees,  pledgees  or  other  successors-in-interest  will  be the  selling
beneficial owners for purposes of this Prospectus.


     Broker-dealers  engaged by the Selling  Stockholders  may arrange for other
brokers-dealers to participate in sales.  Broker-dealers may receive commissions
or discounts from the Selling  Stockholders  (or, if any  broker-dealer  acts as
agent  for the  purchaser  of  shares,  from the  purchaser)  in  amounts  to be
negotiated.  The  Selling  Stockholders  do not  expect  these  commissions  and
discounts to exceed what is customary in the types of transactions involved.

     National Securities Corporation ("NSC") has indicated to us its willingness
to act as  selling  agent on behalf  of the  Selling  Stockholders  named in the
Prospectus under "Selling  Security Holders" that purchased our privately placed
securities.  All shares sold, if any, on behalf of Selling  Stockholders  by NSC
would be in  transactions  executed  by NSC on an agency  basis and  commissions
charged to its customers in connection with each transaction  shall not exceed a
maximum of 5% of the gross proceeds. NSC does not have an underwriting agreement
with us and/or the Selling Stockholders and no Selling Stockholders are required
to execute transactions through NSC.

     In connection with the sale of our Common Stock or interests  therein,  the
Selling  Stockholders may enter into hedging transactions with broker-dealers or
other  financial  institutions,  which may in turn  engage in short sales of the
common stock in the course of hedging the  positions  they  assume.  The Selling
Stockholders  may also sell shares of our Common  Stock short and deliver  these
securities  to close out their  short  positions,  or loan or pledge  the Common
Stock to  broker-dealers  that in turn may sell these  securities.  The  Selling
Stockholders   may  also  enter   into   option  or  other   transactions   with
broker-dealers  or other  financial  institutions or the creation of one or more
derivative  securities which require the delivery to such broker-dealer or other
financial  institution of shares offered by this  Prospectus,  which shares such
broker-dealer  or  other  financial  institution  may  resell  pursuant  to this
Prospectus (as supplemented or amended to reflect such transaction).

     The Selling  Stockholders will receive the aggregate proceeds from the sale
of the Common  Stock  offered by them.  The  aggregate  proceeds  to the Selling
Stockholders  from the sale of the  Common  Stock  offered  by them  will be the
purchase price of the Common Stock less discounts or  commissions,  if any. Each
of the Selling  Stockholders  reserves  the right to accept and,  together  with
their  agents from time to time,  to reject,  in whole or in part,  any proposed
purchase  of Common  Stock to be made  directly or through  agents.  We will not
receive any of the proceeds from the sale of Common Stock in this  offering.  We
may receive  proceeds  from  holders who  exercise  their  warrants  and pay the
applicable cash exercise price in connection with those exercises.

     The Selling  Stockholders also may resell all or a portion of the shares in
open market  transactions  in reliance upon Rule 144 under the Securities Act of
1933,  provided that they meet the criteria and conform to the  requirements  of
that rule.

     The Selling  Stockholders and any  underwriters,  broker-dealers  or agents
that  participate  in the sale of the Common Stock or  interests  therein may be
"underwriters"  within  the  meaning  of  Section  2(11)  of the 1933  Act.  Any
discounts,  commissions,  concessions  or profit  they earn on any resale of the
shares may be underwriting discounts and commissions under the 1933 Act. Selling
Stockholders who are  "underwriters"  within the meaning of Section 2(11) of the
1933 Act will be subject to the  prospectus  delivery  requirements  of the 1933
Act.

     To the extent  required,  the shares of our  common  stock to be sold,  the
names of the Selling  Stockholders,  the respective  purchase  prices and public
offering prices, the names of any agent,  dealer or underwriter,  any applicable


commissions or discounts with respect to a particular offer will be set forth in
an  accompanying  prospectus  supplement or, if  appropriate,  a  post-effective
amendment to the registration statement that includes this Prospectus.

     In order to comply with the securities laws of some states,  if applicable,
the Common Stock may be sold in these  jurisdictions  only through registered or
licensed  brokers or dealers.  In addition,  in some states the Common Stock may
not be sold unless it has been  registered or qualified for sale or an exemption
from  registration  or  qualification  requirements is available and is complied
with.

     We have advised the Selling Stockholders that the  anti-manipulation  rules
of  Regulation  M under the 1934 Act may apply to sales of shares in the  market
and to the  activities  of the Selling  Stockholders  and their  affiliates.  In
addition,  we will make copies of this  Prospectus (as it may be supplemented or
amended from time to time) available to the Selling Stockholders for the purpose
of satisfying the prospectus delivery  requirements of the 1933 Act. The Selling
Stockholders may indemnify any  broker-dealer  that participates in transactions
involving  the sale of the shares of Common Stock against  certain  liabilities,
including liabilities arising under the 1933 Act.

     We  will  pay all of the  expenses  incident  to  registration  other  than
commissions, fees and discounts of underwriters, brokers, dealers and agents. We
will pay for offering expenses  including the SEC registration  fee,  accounting
fees, legal fees, printing expenses and other related miscellaneous expenses. We
have agreed to indemnify the Selling Stockholders against liabilities, including
liabilities  under  the 1933 Act and  state  securities  laws,  relating  to the
registration of the shares offered by this Prospectus.

     We have  agreed  with the  Selling  Stockholders  to keep the  registration
statement  of which  this  Prospectus  constitutes  a part  effective  until the
earlier of (1) such time as all of the shares  covered by this  Prospectus  have
been disposed of pursuant to and in accordance with the  registration  statement
or (2) the date on which the shares may be sold  pursuant  to Rule 144(k) of the
1933  Act.  Notwithstanding  anything  contained  herein  to  the  contrary,  an
aggregate of ________  shares of Common Stock issuable upon exercise of warrants
held by NSC and/or "associated  persons" of NSC are subject to a 180 day lock-up
agreement in accordance with the requirements of NASD Rule 2710(g)(1).
