[insert investor name] (the "Holder"),  is entitled,  upon the terms and subject
to the limitations on exercise and the conditions  hereinafter set forth, at any
time on or after July 10, 2003 (the "Initial  Exercise Date") and on or prior to

purchase  price of one share of Common Stock (the  "Exercise  Price") under this
Warrant shall be $12.80 subject to adjustment hereunder.  The Exercise Price and
the number of  Warrant  Shares for which the  Warrant  is  exercisable  shall be
subject  to  adjustment  as  provided  herein.  CAPITALIZED  TERMS  USED AND NOT
OTHERWISE  DEFINED  HEREIN  SHALL HAVE THE  MEANINGS  SET FORTH IN THAT  CERTAIN
SECURITIES PURCHASE AGREEMENT (THE "PURCHASE  AGREEMENT"),  DATED JULY 10, 2003,
BETWEEN THE COMPANY AND THE PURCHASERS SIGNATORY THERETO.

     1.  Title  to  Warrant.  Prior  to the  Termination  Date  and  subject  to
compliance with applicable laws and Section 7 of this Warrant,  this Warrant and
all rights hereunder are  transferable,  in whole but not in part, at the office
or agency of the Company by the Holder in person or by duly authorized attorney,
upon surrender of this Warrant  together with the Assignment Form annexed hereto
properly  endorsed.  The transferee shall sign an investment  letter in form and
substance reasonably satisfactory to the Company.

     2.  Authorization of Shares.  The Company covenants that all Warrant Shares
which may be issued upon the exercise of the purchase rights represented by this
Warrant will, upon exercise of the purchase rights  represented by this Warrant,
be duly authorized, validly

<PAGE>

issued,  fully paid and nonassessable and free from all taxes, liens and charges
in respect of the issue  thereof  (other  than taxes in respect of any  transfer
occurring contemporaneously with such issue).

     3. Exercise of Warrant.

          (a) Except as provided in Section 4 herein,  exercise of the  purchase
     rights  represented by this Warrant may be made at any time on or after the
     Initial  Exercise Date and on or before the Termination Date for all of the
     Warrant Shares  purchasable  hereunder by the surrender of this Warrant and
     the Notice of Exercise Form annexed hereto duly executed,  at the office of
     the  Company  (or such  other  office or agency  of the  Company  as it may
     designate by notice in writing to the  registered  Holder at the address of
     such Holder  appearing on the books of the Company) and upon payment of the
     Exercise Price of all of the shares  thereby  purchased by wire transfer or
     cashier's check drawn on a United States bank, the Holder shall be entitled
     to receive a  certificate  for the number of Warrant  Shares so  purchased.
     Certificates  for shares  purchased  hereunder  shall be  delivered  to the
     Holder  within  seven (7) Trading Days after the date on which this Warrant
     shall have been  exercised as  aforesaid.  This Warrant  shall be deemed to
     have been exercised and such certificate or certificates shall be deemed to
     have been issued,  and Holder or any other person so designated to be named
     therein  shall be deemed to have  become a holder of record of such  shares
     for all purposes,  as of the date the Warrant has been exercised by payment
     to the Company of the Exercise  Price and all taxes  required to be paid by
     the Holder,  if any,  pursuant  to Section 5 prior to the  issuance of such
     shares,  have been paid.  Nothing  herein  shall limit a Holder's  right to
     pursue any other  remedies  available to it hereunder,  at law or in equity
     including,  without  limitation,  a decree of specific  performance  and/or
     injunctive  relief with respect to the Company's  failure to timely deliver
     certificates  representing  shares of Common  Stock  upon  exercise  of the
     Warrant as required pursuant to the terms hereof.

          (b) In the event that (i) the closing  price of the  Company's  Common
     Stock  (or in case no sales are  reported  on any given  Trading  Day,  the
     average of the closing bid and asked prices of the  Company's  Common Stock
     on the  Trading  Market  for  such  Trading  Day) is at  least  130% of the
     Exercise Price then in effect for 30 consecutive Trading Days, and (ii) the
     Registration Statement has been declared effective by the Commission,  this
     Warrant  shall be  automatically  exercised  in full.  In such  case,  upon
     receipt of written notice form the Company of such automatic exercise,  the
     Holder  shall  deliver to the Company the Notice of Exercise  Form  annexed
     hereto and shall pay to the Company an amount equal to the  Exercise  Price
     times all Warrant Shares  purchasable  hereunder (the  "Aggregate  Exercise
     Price")  within 10 Trading  Days of receipt of such  notice to effect  such
     automatic  exercise.  As  promptly  as  practicable  after  receipt  of the
     Aggregate  Exercise Price,  the Company shall deliver to the Holder a stock
     certificate or certificates representing such Warrant Shares.

          (c) This  Warrant  shall  only be  exercised  for the full  amount  of
     Warrant  Shares that are  issuable  hereunder.  The Holder may not effect a
     partial exercise of this Warrant.

     4.  No  Fractional   Shares  or  Scrip.  No  fractional   shares  or  scrip
representing  fractional  shares  shall  be  issued  upon the  exercise  of this
Warrant.  As to any fraction of a share which Holder would otherwise be entitled
to purchase  upon such  exercise,  the Company  shall pay a cash  adjustment  in
respect of such final fraction in an amount equal to such fraction multiplied by
the Exercise Price.

                                       2
<PAGE>

     5. Charges, Taxes and Expenses. Issuance of certificates for Warrant Shares
shall be made  without  charge to the  Holder for any issue or  transfer  tax or
other incidental expense in respect of the issuance of such certificate,  all of
which taxes and  expenses  shall be paid by the Company,  and such  certificates
shall be  issued  in the name of the  Holder  or in such name or names as may be
directed by the Holder;  provided,  however,  that in the event certificates for
Warrant  Shares are to be issued in a name  other  than the name of the  Holder,
this  Warrant  when  surrendered  for  exercise  shall  be  accompanied  by  the
Assignment Form attached hereto duly executed by the Holder; and the Company may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

     6. Closing of Books.  The Company will not close its  stockholder  books or
records in any  manner  which  prevents  the timely  exercise  of this  Warrant,
pursuant to the terms hereof.

     7. Transfer, Division and Combination.

          (a) Subject to compliance with any applicable  securities laws and the
     conditions set forth in Sections 1 and 7(d) hereof and to the provisions of
     Section  4.1 of  the  Purchase  Agreement,  this  Warrant  and  all  rights
     hereunder are  transferable,  in whole but not in part,  upon  surrender of
     this  Warrant  at the  principal  office of the  Company,  together  with a
     written  assignment  of this  Warrant  substantially  in the form  attached
     hereto  duly  executed  by the  Holder or its agent or  attorney  and funds
     sufficient  to pay any  transfer  taxes  payable  upon the  making  of such
     transfer.  Upon such surrender and, if required,  such payment, the Company
     shall  execute and deliver a new Warrant in the name of the assignee and in
     the  denomination  specified in such  instrument of  assignment,  and shall
     issue to the  assignor a new Warrant  and this  Warrant  shall  promptly be
     cancelled.  A Warrant,  if properly  assigned,  may be  exercised  by a new
     holder for the  purchase  of Warrant  Shares  without  having a new Warrant
     issued.

          (b) The Company  shall  prepare,  issue and deliver at its own expense
     (other than transfer  taxes) the new Warrant or Warrants under this Section
     7.

          (c) The Company agrees to maintain, at its aforesaid office, books for
     the registration and the registration of transfer of the Warrants.

          (d) If, at the time of the  surrender  of this  Warrant in  connection
     with any transfer of this  Warrant,  the transfer of this Warrant shall not
     be registered  pursuant to an effective  registration  statement  under the
     Securities Act and under  applicable state securities or blue sky laws, the
     Company may require,  as a condition of allowing such transfer (i) that the
     Holder or transferee of this  Warrant,  as the case may be,  furnish to the
     Company a written  opinion  of  counsel  (which  opinion  shall be in form,
     substance  and scope  customary  for  opinions  of  counsel  in  comparable
     transactions)  to  the  effect  that  such  transfer  may be  made  without
     registration under the Securities Act and under applicable state securities
     or blue sky laws, (ii) that the holder or transferee execute and deliver to
     the Company an investment  letter in form and  substance  acceptable to the
     Company  and (iii)  that the  transferee  be an  "accredited  investor"  as
     defined in Rule 501(a) promulgated under the Securities Act.

     8. No Rights as Stockholder  until Exercise.  This Warrant does not entitle
the Holder to any voting rights or other rights as a stockholder  of the Company
prior to the exercise hereof. Upon the surrender of this Warrant and the payment
of the aggregate Exercise Price, the

                                       3
<PAGE>

Warrant  Shares so purchased  shall be and be deemed to be issued to such Holder
as the record  owner of such  shares as of the close of business on the later of
the date of such surrender or payment.

     9. Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants
that upon receipt by the Company of evidence  reasonably  satisfactory  to it of
the  loss,  theft,  destruction  or  mutilation  of this  Warrant  or any  stock
certificate  relating  to the  Warrant  Shares,  and in case of  loss,  theft or
destruction,  of indemnity or security reasonably  satisfactory to it (which, in
the case of the  Warrant,  shall not include the posting of any bond),  and upon
surrender and cancellation of such Warrant or stock  certificate,  if mutilated,
the Company  will make and deliver a new  Warrant or stock  certificate  of like
tenor  and  dated  as of such  cancellation,  in lieu of such  Warrant  or stock
certificate.

     10. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the
taking of any action or the  expiration of any right  required or granted herein
shall be a Saturday, Sunday or a legal holiday, then such action may be taken or
such right may be exercised on the next succeeding day not a Saturday, Sunday or
legal holiday.

     11.  Adjustments  of  Exercise  Price and Number of Warrant  Shares;  Stock
Splits, etc. The number and kind of securities  purchasable upon the exercise of
this Warrant and the Exercise Price shall be subject to adjustment  from time to
time upon the happening of any of the  following.  In case the Company shall (i)
pay a dividend  in shares of Common  Stock or make a  distribution  in shares of
Common Stock to holders of its  outstanding  Common  Stock,  (ii)  subdivide its
outstanding  shares  of Common  Stock  into a greater  number of  shares,  (iii)
combine its  outstanding  shares of Common Stock into a smaller number of shares
of  Common  Stock,  or  (iv)  issue  any  shares  of  its  capital  stock  in  a
reclassification  of the  Common  Stock,  then  the  number  of  Warrant  Shares
purchasable  upon  exercise of this Warrant  immediately  prior thereto shall be
adjusted so that the Holder  shall be entitled to receive the kind and number of
Warrant  Shares or other  securities of the Company which it would have owned or
have been  entitled  to  receive  had such  Warrant  been  exercised  in advance
thereof.  Upon each such  adjustment of the kind and number of Warrant Shares or
other  securities of the Company  which are  purchasable  hereunder,  the Holder
shall  thereafter be entitled to purchase the number of Warrant  Shares or other
securities resulting from such adjustment at an Exercise Price per Warrant Share
or  other  security  obtained  by  multiplying  the  Exercise  Price  in  effect
immediately prior to such adjustment by the number of Warrant Shares purchasable
pursuant hereto  immediately prior to such adjustment and dividing by the number
of  Warrant  Shares  or other  securities  of the  Company  resulting  from such
adjustment. An adjustment made pursuant to this paragraph shall become effective
immediately  after the effective  date of such event  retroactive  to the record
date, if any, for such event.

     12. Reorganization,  Reclassification, Merger, Consolidation or Disposition
of Assets.  In case the Company shall  reorganize  its capital,  reclassify  its
capital stock,  consolidate or merge with or into another corporation (where the
Company  is not the  surviving  corporation  or where  there  is a change  in or
distribution with respect to the Common Stock of the Company), or sell, transfer
or  otherwise  dispose  of all or  substantially  all its  property,  assets  or
business   to  another   corporation   and,   pursuant  to  the  terms  of  such
reorganization,   reclassification,  merger,  consolidation  or  disposition  of
assets, shares of common stock of the successor or acquiring corporation, or any
cash,  shares of stock or other securities or property of any nature  whatsoever
(including  warrants or other subscription or purchase rights) in addition to or
in lieu of common

                                       4
<PAGE>

stock of the successor or acquiring  corporation ("Other  Property"),  are to be
received by or distributed  to the holders of Common Stock of the Company,  then
the Holder  shall have the right  thereafter  to  receive,  at the option of the
Holder,  upon exercise of this Warrant,  the number of shares of Common Stock of
the successor or acquiring corporation or of the Company, if it is the surviving
corporation,  and  Other  Property  receivable  upon  or  as a  result  of  such
reorganization, reclassification, merger, consolidation or disposition of assets
by a Holder of the number of shares of Common  Stock for which  this  Warrant is
exercisable immediately prior to such event. In case of any such reorganization,
reclassification,  merger, consolidation or disposition of assets, the successor
or acquiring  corporation (if other than the Company) shall expressly assume the
due and  punctual  observance  and  performance  of each and every  covenant and
condition of this  Warrant to be  performed  and observed by the Company and all
the obligations and liabilities hereunder,  subject to such modifications as may
be deemed appropriate (as determined in good faith by resolution of the Board of
Directors of the Company) in order to provide for  adjustments of Warrant Shares
for which this Warrant is  exercisable  which shall be as nearly  equivalent  as
practicable to the adjustments  provided for in this Section 12. For purposes of
this Section 12, "common stock of the successor or acquiring  corporation" shall
include  stock of such  corporation  of any class which is not  preferred  as to
dividends or assets over any other class of stock of such  corporation and which
is  not  subject  to  redemption   and  shall  also  include  any  evidences  of
indebtedness,  shares of stock or other securities which are convertible into or
exchangeable  for any such stock,  either  immediately  or upon the arrival of a
specified  date or the happening of a specified  event and any warrants or other
rights to subscribe for or purchase any such stock. The foregoing  provisions of
this  Section  12  shall   similarly   apply  to   successive   reorganizations,
reclassifications, mergers, consolidations or disposition of assets.

     13. Voluntary Adjustment by the Company. The Company, subject to compliance
with its Bylaws, may at any time during the term of this Warrant reduce the then
current  Exercise  Price  to any  amount  and for  any  period  of  time  deemed
appropriate by the Board of Directors of the Company.

     14. Notice of  Adjustment.  Whenever the number of Warrant Shares or number
or kind of securities or other  property  purchasable  upon the exercise of this
Warrant or the Exercise Price is adjusted, as herein provided, the Company shall
give  notice  thereof to the  Holder,  which  notice  shall  state the number of
Warrant Shares (and other securities or property)  purchasable upon the exercise
of this  Warrant  and the  Exercise  Price of such  Warrant  Shares  (and  other
securities or property) after such  adjustment,  setting forth a brief statement
of the facts  requiring  such  adjustment  and setting forth the  computation by
which such adjustment was made.

     15. Notice of Corporate Action. If at any time:

          (a) the Company shall take a record of the holders of its Common Stock
     for  the  purpose  of  entitling  them  to  receive  a  dividend  or  other
     distribution,  or any right to subscribe  for or purchase any  evidences of
     its indebtedness,  any shares of stock of any class or any other securities
     or property, or to receive any other right, or

          (b) there  shall be any capital  reorganization  of the  Company,  any
     reclassification or recapitalization of the capital stock of the Company or
     any  consolidation or merger of the Company with, or any sale,  transfer or
     other  disposition  of all or  substantially  all the  property,  assets or
     business of the Company to, another corporation, or

                                       5
<PAGE>

          (c) there shall be a voluntary or involuntary dissolution, liquidation
     or winding up of the Company;

then, in any one or more of such cases,  the Company shall give to Holder (i) at
least 20 days prior  written  notice of the date on which a record date shall be
selected for such dividend,  distribution or right or for determining  rights to
vote  in  respect  of  any  such   reorganization,   reclassification,   merger,
consolidation, sale, transfer, disposition,  liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 20
days  prior  written  notice of the date when the same shall  take  place.  Such
notice in accordance  with the foregoing  clause also shall specify (i) the date
on which  any such  record  is to be taken  for the  purpose  of such  dividend,
distribution  or right,  the date on which the holders of Common  Stock shall be
entitled  to any such  dividend,  distribution  or  right,  and the  amount  and
character  thereof,  and  (ii)  the  date  on  which  any  such  reorganization,
reclassification,    merger,   consolidation,   sale,   transfer,   disposition,
dissolution,  liquidation  or winding  up is to take place and the time,  if any
such  time is to be fixed,  as of which the  holders  of Common  Stock  shall be
entitled to exchange  their  Warrant  Shares for  securities  or other  property
deliverable upon such disposition,  dissolution, liquidation or winding up. Each
such written  notice shall be  sufficiently  given if addressed to Holder at the
last address of Holder  appearing  on the books of the Company and  delivered in
accordance with Section 17(d).

     16.  Authorized  Shares.  The Company  covenants that during the period the
Warrant is outstanding,  it will reserve from its authorized and unissued Common
Stock a  sufficient  number of shares to provide for the issuance of the Warrant
Shares upon the exercise of any purchase rights under this Warrant.  The Company
further  covenants  that its  issuance of this  Warrant  shall  constitute  full
authority  to its  officers  who are charged  with the duty of  executing  stock
certificates  to execute and issue the  necessary  certificates  for the Warrant
Shares upon the exercise of the purchase rights under this Warrant.  The Company
will take all such  reasonable  action as may be  necessary  to assure that such
Warrant  Shares  may be issued  as  provided  herein  without  violation  of any
applicable law or regulation,  or of any requirements of the Trading Market upon
which the Common Stock may be listed.

          Except and to the extent as waived or consented to by the Holder,  the
     Company shall not by any action,  including,  without limitation,  amending
     its certificate of incorporation or through any reorganization, transfer of
     assets, consolidation,  merger, dissolution, issue or sale of securities or
     any  other  voluntary  action,  avoid or seek to avoid  the  observance  or
     performance  of any of the terms of this Warrant,  but will at all times in
     good faith  assist in the  carrying out of all such terms and in the taking
     of all such  actions as may be  necessary  or  appropriate  to protect  the
     rights of Holder as set forth in this Warrant against  impairment.  Without
     limiting the generality of the foregoing, the Company will (a) not increase
     the par value of any Warrant Shares above the amount payable  therefor upon
     such exercise immediately prior to such increase in par value, (b) take all
     such action as may be  necessary or  appropriate  in order that the Company
     may validly and legally issue fully paid and  nonassessable  Warrant Shares
     upon the  exercise of this  Warrant,  and (c) use  commercially  reasonable
     efforts to obtain all such authorizations,  exemptions or consents from any
     public regulatory body having  jurisdiction  thereof as may be necessary to
     enable the Company to perform its obligations under this Warrant.

                                       6
<PAGE>

          Before  taking any action which would result in an  adjustment  in the
     number of Warrant  Shares for which this Warrant is  exercisable  or in the
     Exercise  Price,  the  Company  shall  obtain  all such  authorizations  or
     exemptions  thereof,  or consents  thereto,  as may be  necessary  from any
     public regulatory body or bodies having jurisdiction thereof.

          17. Miscellaneous.

               (a) Jurisdiction.  This Warrant shall constitute a contract under
          the  laws  of  Delaware,  without  regard  to  its  conflict  of  law,
          principles or rules.

               (b) Restrictions. The Holder acknowledges that the Warrant Shares
          acquired upon the exercise of this Warrant,  if not  registered,  will
          have restrictions upon resale imposed by state and federal  securities
          laws.

               (c) Nonwaiver and Expenses.  No course of dealing or any delay or
          failure to exercise  any right  hereunder  on the part of Holder shall
          operate  as a waiver of such  right or  otherwise  prejudice  Holder's
          rights,  powers or  remedies,  notwithstanding  all  rights  hereunder
          terminate  on the  Termination  Date.  If the  Company  willfully  and
          knowingly  fails to comply with any provision of this  Warrant,  which
          results in any material  damages to the Holder,  the Company shall pay
          to Holder such amounts as shall be  sufficient  to cover any costs and
          expenses  including,  but not limited to, reasonable  attorneys' fees,
          including  those of  appellate  proceedings,  incurred  by  Holder  in
          collecting any amounts due pursuant  hereto or in otherwise  enforcing
          any of its rights, powers or remedies hereunder.

               (d) Notices.  Any notice,  request or other document  required or
          permitted to be given or delivered to the Holder by the Company  shall
          be delivered in accordance with the notice  provisions of the Purchase
          Agreement.

               (e) Limitation of Liability.  No provision hereof, in the absence
          of any  affirmative  action by  Holder to  exercise  this  Warrant  or
          purchase  Warrant Shares,  and no enumeration  herein of the rights or
          privileges  of Holder,  shall give rise to any liability of Holder for
          the  purchase  price of any Common  Stock or as a  stockholder  of the
          Company,  whether  such  liability  is  asserted  by the Company or by
          creditors of the Company.

               (f) Remedies.  Holder,  in addition to being entitled to exercise
          all rights  granted by law,  including  recovery of  damages,  will be
          entitled to specific performance of its rights under this Warrant. The
          Company   agrees  that   monetary   damages   would  not  be  adequate
          compensation  for any loss incurred by reason of a breach by it of the
          provisions  of this Warrant and hereby  agrees to waive the defense in
          any  action  for  specific  performance  that a remedy at law would be
          adequate.

               (g)  Successors  and Assigns.  Subject to  applicable  securities
          laws,  this Warrant and the rights and  obligations  evidenced  hereby
          shall inure to the benefit of and be binding  upon the  successors  of
          the Company and the  successors and permitted  assigns of Holder.  The
          provisions  of this  Warrant are intended to be for the benefit of all
          Holders from time to time of this Warrant and shall be  enforceable by
          any such Holder or holder of Warrant Shares.

               (h)  Amendment.  This  Warrant  may be modified or amended or the
          provisions  hereof waived with the written  consent of the Company and
          the Holder.

                                       7
<PAGE>

               (i)  Severability.  Wherever  possible,  each  provision  of this
          Warrant  shall be  interpreted  in such manner as to be effective  and

<PAGE>

          hereunder shall contain (except if otherwise  directed by the Holders)

          shall cause such Registration Statement to become effective and remain

          reasonable efforts to cause each Registration Statement to be declared
          effective  under the  Securities Act as promptly as possible after the
          filing  thereof,  but in any event not  later  than the  Effectiveness
          Date, and shall use its commercially  reasonable  efforts to keep such
          Registration Statement continuously effective under the Securities Act
          until  the  date  which  is  two  years   after  the  date  that  such
          Registration Statement is declared effective by the Commission or such
          earlier  date  when  all  Registrable   Securities   covered  by  such
          Registration  Statement  have been sold or may be sold without  volume
          restrictions  pursuant to Rule 144(k) as  determined by the counsel to
          the  Company  pursuant  to a written  opinion  letter to such  effect,
          addressed  and  acceptable  to the  Company's  transfer  agent and the
          affected Holders (the "Effectiveness Period").

               (b) If a  Registration  Statement  filed or  required to be filed
          hereunder is not declared effective by the Commission on or before the
          Effectiveness Date (any such failure or breach to be referred to as an
          "Event")  then in  addition  to any other  rights the Holders may have
          hereunder  or under  applicable  law: (x) on the seventh day after the
          date of such Event (the "Event  Date"),  the Company shall pay to each
          Holder an amount in cash or shares of the  Company's  Common Stock (at
          the Company's  option),  as  liquidated  damages and not as a penalty,
          equal to 1.5% of the  aggregate  purchase  price  paid by such  Holder
          pursuant to the Purchase Agreement for any Registrable Securities then
          held  by  such  Holder;  and  (y)  on  seventh  day  of  each  monthly
          anniversary of each such Event Date (if the applicable Event shall not
          have been cured by such date) until the applicable Event is cured, the
          Company  shall  pay to each  Holder an amount in cash or shares of the
          Company's  Common  Stock  (at the  Company's  option),  as  liquidated
          damages and not as a penalty,  equal to 1.5% of the aggregate purchase
          price paid by such Holder  pursuant to the Purchase  Agreement for any
          Registrable Securities then held by such Holder.

               (c) If during the Effectiveness Period, the number of Registrable
          Securities  at any time exceeds 100% of the number of shares of Common
          Stock then  registered in a Registration  Statement,  then the Company
          shall file as soon as reasonably  practicable but in any case prior to
          the  applicable  Filing Date,  an  additional  Registration  Statement
          covering  the  resale of by the  Holders  of not less than 100% of the
          number of such Registrable Securities.

     3. Registration Procedures

               In  connection  with  the  Company's   registration   obligations

          copies of all such documents proposed to be filed (including documents
          incorporated  or  deemed  incorporated  by  reference  to  the  extent
          requested  by such  Person)  which  documents  will be  subject to the
          review of such

          Holders,  and (ii)  cause its  officers  and  directors,  counsel  and
          independent  certified public accountants to respond to such inquiries
          as shall be necessary, in the reasonable opinion of respective counsel

          Securities Act. The Company shall not file a Registration Statement or
          any such Prospectus or any amendments or supplements  thereto to which
          the  Holders  of  a  majority  of  the  Registrable  Securities  shall
          reasonably object.

               (b) (i) Prepare  and file with the  Commission  such  amendments,
          including post-effective  amendments,  to a Registration Statement and

          keep  a  Registration  Statement  continuously  effective  as  to  the
          applicable  Registrable  Securities for the  Effectiveness  Period and
          prepare  and file with the  Commission  such  additional  Registration
          Statements  in order to register for resale under the  Securities  Act
          all of the Registrable  Securities;  (ii) cause the related Prospectus
          to be amended or supplemented by any required  Prospectus  supplement,
          and as so  supplemented  or amended to be filed  pursuant to Rule 424;
          (iii)  respond as promptly as  reasonably  possible,  and in any event
          within fifteen days, to any comments received from the Commission with
          respect to a Registration  Statement or any amendment  thereto and, as
          promptly as reasonably  possible,  upon  request,  provide the Holders
          true  and  complete  copies  of  all  correspondence  from  and to the
          Commission relating to such Registration Statement; and (iv) comply in
          all material  respects with the  provisions of the  Securities Act and
          the Exchange Act with respect to the  disposition  of all  Registrable
          Securities  covered by a Registration  Statement during the applicable
          period in accordance  with the intended  methods of disposition by the
          Holders thereof set forth in a Registration Statement as so amended or
          in such Prospectus as so supplemented.

               (c) Notify the Holders of  Registrable  Securities  to be sold as
          promptly as reasonably possible (and, in the case of (i)(A) below, not
          less than three  Trading Days prior to such filing) and (if  requested
          by any such Person) confirm such notice in writing promptly  following
          the day (i)(A)  when a  Prospectus  or any  Prospectus  supplement  or
          post-effective amendment to a Registration Statement is proposed to be
          filed; (B) when the Commission notifies the Company whether there will
          be a "review" of a Registration  Statement and whenever the Commission
          comments in writing on such Registration  Statement (the Company shall
          upon request  provide true and complete copies thereof and all written
          responses  thereto to each of the Holders);  and (C) with respect to a
          Registration Statement or any post-effective  amendment, when the same
          has become  effective;  (ii) of any request by the  Commission  or any
          other  Federal or state  governmental  authority  during the period of
          effectiveness   of  a   Registration   Statement  for   amendments  or
          supplements  to  a   Registration   Statement  or  Prospectus  or  for
          additional information; (iii) of the issuance by the Commission or any
          other  federal  or state  governmental  authority  of any  stop  order
          suspending the effectiveness of a Registration  Statement covering any
          or  all  of  the  Registrable  Securities  or  the  initiation  of any
          Proceedings  for that  purpose;  (iv) of the receipt by the Company of
          any notification  with respect to the suspension of the  qualification
          or exemption from  qualification of any of the Registrable  Securities
          for sale in any jurisdiction,  or the initiation or threatening of any
          Proceeding for such purpose; and (v) of the occurrence of any event or
          passage  of time that makes the  financial  statements  included  in a
          Registration   Statement  ineligible

                                       4
<PAGE>

          for  inclusion  therein  or any  statement  made in such  Registration
          Statement or Prospectus or any document  incorporated  or deemed to be
          incorporated  therein by reference  untrue in any material  respect or
          that requires any revisions to such Registration Statement, Prospectus
          or other documents so that, in the case of a Registration Statement or
          the  Prospectus,  as the case may be, it will not  contain  any untrue
          statement  of a  material  fact or omit to  state  any  material  fact
          required  to be stated  therein or  necessary  to make the  statements
          therein, in light of the circumstances under which they were made, not
          misleading.

               (d) Use its commercially reasonable efforts to avoid the issuance
          of, or, if issued,  obtain the withdrawal of (i) any order  suspending
          the effectiveness of a Registration  Statement, or (ii) any suspension
          of the qualification  (or exemption from  qualification) of any of the
          Registrable  Securities for sale in any jurisdiction,  at the earliest
          practicable moment.

               (e)  Furnish  to  each  Holder,  without  charge,  at  least  one
          conformed  copy of each  Registration  Statement  and  each  amendment
          thereto,  including financial statements and schedules,  all documents
          incorporated or deemed to be incorporated  therein by reference to the
          extent  reasonably  requested by such Person,  and all exhibits to the
          extent reasonably requested by such Person (including those previously
          furnished or incorporated  by reference)  promptly after the filing of
          such documents with the Commission.

               (f) Promptly  deliver to each  Holder,  without  charge,  as many
          copies  of the  Prospectus  or  Prospectuses  (including  each form of
          prospectus)  and each amendment or supplement  thereto as such Persons
          may reasonably request. The Company hereby consents to the use of such
          Prospectus  and each  amendment or  supplement  thereto by each of the
          selling  Holders  in  connection  with  the  offering  and sale of the
          Registrable Securities covered by such Prospectus and any amendment or
          supplement thereto.

               (g) Prior to any public offering of Registrable  Securities,  use
          its  commercially   reasonable  efforts  to  register  or  qualify  or
          cooperate with the selling Holders in connection with the registration
          or   qualification   (or   exemption   from   such   registration   or
          qualification) of such Registrable Securities for offer and sale under
          the  securities  or Blue Sky  laws of such  jurisdictions  within  the
          United States as any Holder  reasonably  requests in writing,  to keep
          each such  registration  or  qualification  (or  exemption  therefrom)
          effective during the Effectiveness  Period and to do any and all other
          acts or  things  reasonably  necessary  or  advisable  to  enable  the
          disposition  in  such  jurisdictions  of  the  Registrable  Securities
          covered by a Registration Statement;  provided, that the Company shall
          not  be  required  to  qualify   generally   to  do  business  in  any
          jurisdiction where it is not then so qualified, subject the Company to
          any  material  tax in any  such  jurisdiction  where it is not then so
          subject  or file a general  consent  to service of process in any such
          jurisdiction.

               (h)  Cooperate   with  the  Holders  to  facilitate   the  timely
          preparation  and  delivery of  certificates  representing  Registrable
          Securities to be delivered to a transferee  pursuant to a Registration
          Statement,  which  certificates shall be free, to the extent

                                       5
<PAGE>

          permitted by the Purchase Agreement,  of all restrictive  legends, and
          to enable such Registrable  Securities to be in such denominations and
          registered in such names as any such Holders may request.

               (i) Upon the  occurrence  of any event  contemplated  by  Section
          3(c)(v), as promptly as reasonably  possible,  prepare a supplement or
          amendment,  including a  post-effective  amendment,  to a Registration
          Statement or a supplement  to the related  Prospectus  or any document
          incorporated  or deemed to be incorporated  therein by reference,  and
          file any other  required  document so that, as  thereafter  delivered,
          neither such  Registration  Statement nor such Prospectus will contain
          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, in light of the circumstances under which they were made, not
          misleading.

               (j)  Comply  with all  applicable  rules and  regulations  of the
          Commission.

               (k) The Company may require each selling Holder to furnish to the
          Company a  certified  statement  as to the  number of shares of Common
          Stock  beneficially  owned by such  Holder and,  if  requested  by the
          Commission, the controlling person thereof.

     4. Registration Expenses. All fees and expenses incident to the performance
     of or compliance  with this  Agreement by the Company shall be borne by the
     Company  whether or not any  Registrable  Securities are sold pursuant to a
     Registration Statement.  The fees and expenses referred to in the foregoing
     sentence shall include, without limitation, (i) all registration and filing
     fees (including,  without limitation, fees and expenses (A) with respect to
     filings  required  to be made with the  Trading  Market on which the Common
     Stock is then listed for trading,  and (B) in  compliance  with  applicable
     state  securities  or Blue Sky laws),  (ii) printing  expenses  (including,
     without  limitation,  expenses of  printing  certificates  for  Registrable
     Securities and of printing  prospectuses if the printing of prospectuses is
     reasonably  requested  by the  holders  of a  majority  of the  Registrable
     Securities  included  in  a  Registration   Statement),   (iii)  messenger,
     telephone and delivery expenses, (iv) fees and disbursements of counsel for
     the Company,  (v)  Securities  Act liability  insurance,  if the Company so
     desires such  insurance,  and (vi) fees and  expenses of all other  Persons
     retained  by  the  Company  in  connection  with  the  consummation  of the
     transactions contemplated by this Agreement. In addition, the Company shall
     be responsible for all of its internal expenses incurred in connection with
     the  consummation  of  the  transactions  contemplated  by  this  Agreement
     (including,  without limitation,  all salaries and expenses of its officers
     and employees  performing legal or accounting  duties),  the expense of any
     annual  audit and the fees and  expenses  incurred in  connection  with the
     listing  of the  Registrable  Securities  on  any  securities  exchange  as
     required hereunder.

     5. Indemnification

          (a) Indemnification by the Company. The Company shall, notwithstanding
     any termination of this Agreement, indemnify and hold harmless each Holder,
     the officers,  directors, agents and employees of each of them, each Person
     who  controls  any

                                       6
<PAGE>

     such  Holder  (within the  meaning of Section 15 of the  Securities  Act or
     Section 20 of the Exchange  Act) and the  officers,  directors,  agents and
     employees of each such controlling  Person, to the fullest extent permitted
     by applicable  law, from and against any and all losses,  claims,  damages,
     liabilities,  costs (including,  without limitation,  reasonable attorneys'
     fees) and expenses (collectively, "Losses"), as incurred, arising out of or
     relating  to any  untrue or alleged  untrue  statement  of a material  fact
     contained  in a  Registration  Statement,  any  Prospectus  or any  form of
     prospectus or in any amendment or supplement  thereto or in any preliminary
     prospectus,  or  arising  out of or  relating  to any  omission  or alleged
     omission of a material fact  required to be stated  therein or necessary to
     make  the  statements  therein  (in the case of any  Prospectus  or form of
     prospectus or supplement thereto, in light of the circumstances under which
     they were  made) not  misleading,  except  to the  extent,  but only to the
     extent,  that (1) such untrue statements or omissions are based solely upon
     information  regarding  such Holder  furnished in writing to the Company by
     such  Holder  expressly  for  use  therein,  or to  the  extent  that  such
     information  relates to such  Holder or such  Holder's  proposed  method of
     distribution  of  Registrable  Securities  and was reviewed  and  expressly
     approved  in writing by such  Holder  expressly  for use in a  Registration
     Statement,  such  Prospectus or such form of Prospectus or in any amendment
     or  supplement  thereto (it being  understood  that the Holder has approved
     Annex A hereto for this  purpose) or (2) in the case of an occurrence of an
     event of the type specified in Section 3(c)(ii)-(v), the use by such Holder
     of an outdated or defective  Prospectus after the Company has notified such
     Holder in writing that the Prospectus is outdated or defective and prior to
     the receipt by such Holder of the Advice  contemplated in Section 6(c). The
     Company  shall notify the Holders  promptly of the  institution,  threat or
     assertion  of any  Proceeding  of which the Company is aware in  connection
     with the transactions contemplated by this Agreement.

          (b) Indemnification by Holders.  Each Holder shall,  severally and not
     jointly, indemnify and hold harmless the Company, its directors,  officers,
     agents and  employees,  each Person who  controls  the Company  (within the
     meaning of Section 15 of the  Securities Act and Section 20 of the Exchange
     Act), and the directors,  officers, agents or employees of such controlling
     Persons,  to the fullest  extent  permitted  by  applicable  law,  from and
     against all Losses,  as incurred,  arising out of or based solely upon: (x)
     such Holder's failure to comply with the prospectus  delivery  requirements
     of the Securities  Act or (y) any untrue or alleged  untrue  statement of a
     material fact contained in any Registration Statement,  any Prospectus,  or
     any form of prospectus, or in any amendment or supplement thereto or in any
     preliminary  prospectus,  or arising out of or relating to any  omission or
     alleged  omission  of a  material  fact  required  to be stated  therein or
     necessary to make the statements  therein not misleading (i) to the extent,
     but only to the extent, that such untrue statement or omission is contained
     in any  information  so  furnished in writing by such Holder to the Company
     specifically  for  inclusion  in  such   Registration   Statement  or  such
     Prospectus  or (ii) to the  extent  that  (1)  such  untrue  statements  or
     omissions are based upon  information  regarding  such Holder  furnished in
     writing to the Company by such Holder expressly for use therein,  or to the
     extent  that such  information  relates  to such  Holder  or such  Holder's
     proposed method of distribution of Registrable  Securities and was reviewed
     and  expressly  approved in writing by such Holder  expressly  for use in a
     Registration  Statement (it being  understood  that the Holder has approved
     Annex  A  hereto  for  this  purpose),  such  Prospectus  or  such  form of
     Prospectus or in any

                                       7
<PAGE>

     amendment or  supplement  thereto or (2) in the case of an occurrence of an
     event of the type specified in Section 3(c)(ii)-(v), the use by such Holder
     of an outdated or defective  Prospectus after the Company has notified such
     Holder in writing that the Prospectus is outdated or defective and prior to
     the receipt by such Holder of the Advice  contemplated  in Section 6(c). In
     no event shall the liability of any selling Holder  hereunder be greater in
     amount than the dollar amount of the gross proceeds received by such Holder
     upon  the  sale  of  the  Registrable   Securities   giving  rise  to  such
     indemnification obligation.

          (c) Conduct of Indemnification Proceedings. If any Proceeding shall be
     brought or asserted against any Person entitled to indemnity  hereunder (an
     "Indemnified  Party"),  such  Indemnified  Party shall promptly  notify the
     Person from whom indemnity is sought (the "Indemnifying Party") in writing,
     and the  Indemnifying  Party  shall  have the right to assume  the  defense
     thereof, including the employment of counsel reasonably satisfactory to the
     Indemnified  Party and the  payment of all fees and  expenses  incurred  in
     connection  with  defense  thereof;  provided,  that  the  failure  of  any
     Indemnified  Party to give such notice  shall not relieve the  Indemnifying
     Party of its obligations or liabilities pursuant to this Agreement,  except
     (and only) to the extent that it shall be finally  determined by a court of
     competent  jurisdiction  (which  determination  is not subject to appeal or
     further  review) that such failure shall have  prejudiced the  Indemnifying
     Party.

          An Indemnified  Party shall have the right to employ separate  counsel
     in any such Proceeding and to participate in the defense  thereof,  but the
     fees  and  expenses  of  such  counsel  shall  be at the  expense  of  such
     Indemnified Party or Parties unless:  (1) the Indemnifying Party has agreed
     in writing to pay such fees and expenses;  (2) the Indemnifying Party shall
     have failed promptly to assume the defense of such Proceeding and to employ
     counsel  reasonably  satisfactory  to such  Indemnified  Party  in any such
     Proceeding;  or (3) the named parties to any such Proceeding (including any
     impleaded parties) include both such Indemnified Party and the Indemnifying
     Party, and such Indemnified Party shall have been advised by counsel that a
     conflict  of  interest  is  likely  to exist if the  same  counsel  were to
     represent such Indemnified Party and the Indemnifying Party (in which case,
     if such Indemnified  Party notifies the Indemnifying  Party in writing that
     it elects to employ  separate  counsel at the  expense of the  Indemnifying
     Party,  the  Indemnifying  Party  shall not have the  right to  assume  the
     defense  thereof  and the  reasonable  fees and  expenses  of one  separate
     counsel  shall  be  at  the  expense  of  the  Indemnifying   Party).   The
     Indemnifying  Party  shall not be  liable  for any  settlement  of any such
     Proceeding effected without its written consent, which consent shall not be
     unreasonably  withheld.  No  Indemnifying  Party  shall,  without the prior
     written  consent of the  Indemnified  Party,  effect any  settlement of any
     pending  Proceeding in respect of which any  Indemnified  Party is a party,
     unless  such  settlement   includes  an   unconditional   release  of  such
     Indemnified  Party from all liability on claims that are the subject matter
     of such Proceeding.

          All reasonable fees and expenses of the Indemnified  Party  (including
     reasonable  fees and  expenses to the extent  incurred in  connection  with
     investigating  or  preparing  to defend  such  Proceeding  in a manner  not
     inconsistent with this Section) shall be paid to the Indemnified  Party, as
     incurred,  within  ten  Trading  Days  of  written  notice  thereof  to the
     Indemnifying  Party;  provided,  that the Indemnified  Party shall promptly
     reimburse

                                       8
<PAGE>

     the  Indemnifying  Party  for  that  portion  of  such  fees  and  expenses
     applicable to such actions for which such Indemnified Party is not entitled
     to indemnification hereunder,  determined based upon the relative faults of
     the parties.

          (d) Contribution. If a claim for indemnification under Section 5(a) or
     5(b) is unavailable to an Indemnified  Party (by reason of public policy or
     otherwise),  then each  Indemnifying  Party, in lieu of  indemnifying  such
     Indemnified  Party,  shall contribute to the amount paid or payable by such
     Indemnified  Party as a result of such  Losses,  in such  proportion  as is
     appropriate  to reflect the relative  fault of the  Indemnifying  Party and
     Indemnified  Party in connection with the actions,  statements or omissions
     that  resulted  in such  Losses  as well as any  other  relevant  equitable
     considerations.   The  relative  fault  of  such  Indemnifying   Party  and
     Indemnified  Party shall be determined by reference to, among other things,
     whether  any action in  question,  including  any untrue or alleged  untrue
     statement of a material fact or omission or alleged  omission of a material
     fact,  has been taken or made by, or relates to  information  supplied  by,
     such  Indemnifying  Party or Indemnified  Party, and the parties'  relative
     intent,  knowledge,  access to  information  and  opportunity to correct or
     prevent such action, statement or omission. The amount paid or payable by a
     party as a result of any Losses shall be deemed to include,  subject to the
     limitations  set forth in Section 5(c), any reasonable  attorneys' or other
     reasonable  fees or expenses  incurred by such party in connection with any
     Proceeding  to the extent such party would have been  indemnified  for such
     fees or expenses if the  indemnification  provided  for in this Section was
     available to such party in accordance with its terms.

          The parties  hereto  agree that it would not be just and  equitable if
     contribution  pursuant to this  Section  5(d) were  determined  by pro rata
     allocation  or by any other  method of  allocation  that does not take into
     account  the  equitable  considerations  referred  to  in  the  immediately
     preceding  paragraph.  Notwithstanding the provisions of this Section 5(d),
     no Holder shall be required to contribute,  in the aggregate, any amount in
     excess of the amount by which the proceeds actually received by such Holder
     from the  sale of the  Registrable  Securities  subject  to the  Proceeding
     exceeds  the amount of any  damages  that such  Holder has  otherwise  been
     required to pay by reason of such  untrue or alleged  untrue  statement  or
     omission or alleged omission, except in the case of fraud by such Holder.

          The indemnity and  contribution  agreements  contained in this Section
     are in addition to any liability that the Indemnifying  Parties may have to
     the Indemnified Parties.

          6. Miscellaneous

          (a) Remedies.  In the event of a breach by the Company or by a Holder,
     of any of their  obligations  under  this  Agreement,  each  Holder  or the
     Company,  as the case may be, in addition to being entitled to exercise all
     rights  granted  by law and under this  Agreement,  including  recovery  of
     damages,  will be entitled to specific performance of its rights under this
     Agreement.  The Company and each Holder agree that  monetary  damages would
     not provide  adequate  compensation  for any losses incurred by reason of a
     breach by it of any of the  provisions of this Agreement and hereby further
     agrees that, in

                                       9
<PAGE>

     the event of any action for specific performance in respect of such breach,
     it shall waive the defense that a remedy at law would be adequate.

          (b) Compliance.  Each Holder  covenants and agrees that it will comply
     with  the  prospectus  delivery  requirements  of  the  Securities  Act  as
     applicable  to  it in  connection  with  sales  of  Registrable  Securities
     pursuant to a Registration Statement.

          (c) Discontinued Disposition. Each Holder agrees by its acquisition of
     such Registrable Securities that, upon receipt of a notice from the Company
     of the occurrence of any event of the kind described in Section 3(c),  such
     Holder  will  forthwith   discontinue   disposition  of  such   Registrable
     Securities  under a Registration  Statement until such Holder's  receipt of
     the  copies of the  supplemented  Prospectus  and/or  amended  Registration
     Statement or until it is advised in writing  (the  "Advice") by the Company
     that the use of the applicable  Prospectus  may be resumed,  and, in either
     case, has received  copies of any additional or  supplemental  filings that
     are  incorporated  or  deemed  to be  incorporated  by  reference  in  such
     Prospectus or Registration  Statement.  The Company may provide appropriate
     stop orders to enforce the provisions of this paragraph.

          (d)  Amendments  and  Waivers.   The  provisions  of  this  Agreement,
     including the provisions of this sentence, may not be amended,  modified or
     supplemented,  and waivers or consents to  departures  from the  provisions
     hereof may not be given,  unless the same shall be in writing and signed by
     the  Company  and  Holders  holding  at least  50% of the then  outstanding
     Registrable Securities.

          (e) Notices. Any and all notices or other communications or deliveries
     required  or  permitted  to be provided  hereunder  shall be in writing and
     shall be deemed  given and  effective  on the  earliest  of (i) the date of
     transmission, if such notice or communication is delivered via facsimile at
     the facsimile  number  provided for below prior to 6:30 p.m. (New York City
     time)  on  a  Trading  Day,   (ii)  the  Trading  Day  after  the  date  of
     transmission, if such notice or communication is delivered via facsimile at
     the facsimile number provided for below later than 6:30 p.m. (New York City
     time) on any date and earlier than 11:59 p.m.  (New York City time) on such
     date,  (iii) the Trading  Day  following  the date of  mailing,  if sent by
     nationally  recognized  overnight  courier  service,  or (iv)  upon  actual
     receipt  by the party to whom  such  notice is  required  to be given.  The
     address  for  such  notices  and  communications  shall  be  delivered  and
     addressed as set forth in the Purchase Agreement.

          (f) Successors and Assigns.  This Agreement shall inure to the benefit
     of and be binding upon the successors and permitted  assigns of each of the
     parties  and  shall  inure to the  benefit  of each  Holder.  Except to its
     successors,  the Company may not assign its rights or obligations hereunder
     without the prior  written  consent of each Holder.  Each Holder may assign
     their  respective  rights  hereunder  in the manner  and to the  Persons as
     permitted under the Purchase Agreement.

          (g) Execution and Counterparts.  This Agreement may be executed in any
     number of  counterparts,  each of which when so executed shall be deemed to
     be an

                                       10
<PAGE>

     original and, all of which taken together shall constitute one and the same
     Agreement.  In the event  that any  signature  is  delivered  by  facsimile
     transmission, such signature shall create a valid binding obligation of the
     party  executing  (or on whose behalf such  signature is executed) the same
     with the same  force and  effect as if such  facsimile  signature  were the
     original thereof.

          (h)  Governing  Law.  All  questions   concerning  the   construction,
     validity,  enforcement  and  interpretation  of  this  Agreement  shall  be
     governed by and construed and enforced in accordance with the internal laws
     of the State of Delaware,  without regard to the principles of conflicts of
     law thereof.  Each party agrees that all legal  proceedings  concerning the
     interpretations,  enforcement and defense of the transactions  contemplated
     by this Agreement (whether brought against a party hereto or its respective
     affiliates,  directors, officers, shareholders,  employees or agents) shall
     be commenced  exclusively  in the state and federal  courts  sitting in the
     State of Delaware.  Each party  hereto  hereby  irrevocably  submits to the
     exclusive jurisdiction of the state and federal courts sitting in the State
     of Delaware for the adjudication of any dispute  hereunder or in connection
     herewith or with any transaction  contemplated  hereby or discussed  herein
     (including with respect to the  enforcement of the any of this  Agreement),
     and hereby irrevocably waives, and agrees not to assert in any suit, action
     or  proceeding,  any  claim  that  it is  not  personally  subject  to  the
     jurisdiction  of any such court,  that such suit,  action or  proceeding is
     improper.  Each party hereto hereby  irrevocably waives personal service of
     process and consents to process  being  served in any such suit,  action or
     proceeding by mailing a copy thereof via  registered  or certified  mail or
     overnight delivery (with evidence of delivery) to such party at the address
     in effect  for  notices  to it under this  Agreement  and agrees  that such
     service shall constitute good and sufficient  service of process and notice
     thereof.  Nothing  contained herein shall be deemed to limit in any way any
     right to serve  process in any manner  permitted by law.  Each party hereto
     hereby  irrevocably  waives,  to the fullest extent permitted by applicable
     law, any and all right to trial by jury in any legal proceeding arising out
     of or relating to this Agreement or the transactions  contemplated  hereby.
     If either  party  shall  commence  an action or  proceeding  to enforce any
     provisions of this Agreement,  then the prevailing  party in such action or
     proceeding  shall be reimbursed  by the other party for its attorneys  fees
     and other costs and expenses incurred with the  investigation,  preparation
     and prosecution of such action or proceeding.

          (i) Cumulative  Remedies.  The remedies provided herein are cumulative
     and not exclusive of any remedies provided by law.

          (j) Severability.  If any term, provision,  covenant or restriction of
     this Agreement is held by a court of competent  jurisdiction to be invalid,
     illegal,  void or  unenforceable,  the remainder of the terms,  provisions,
     covenants and  restrictions set forth herein shall remain in full force and
     effect and shall in no way be affected,  impaired or  invalidated,  and the
     parties hereto shall use their commercially  reasonable efforts to find and
     employ an alternative  means to achieve the same or substantially  the same
     result  as  that  contemplated  by  such  term,   provision,   covenant  or
     restriction.  It is hereby  stipulated  and declared to be the intention of
     the parties that they would have executed the

                                       11
<PAGE>

     remaining terms,  provisions,  covenants and restrictions without including
     any of such  that  may be  hereafter  declared  invalid,  illegal,  void or
     unenforceable.

          (k) Headings.  The headings in this  Agreement are for  convenience of
     reference only and shall not limit or otherwise affect the meaning hereof.

          (l)  Independent  Nature of Purchasers'  Obligations  and Rights.  The
     obligations of each  Purchaser  hereunder is several and not joint with the
     obligations of any other  Purchaser  hereunder,  and no Purchaser  shall be
     responsible in any way for the  performance of the obligations of any other
     Purchaser hereunder.  Nothing contained herein or in any other agreement or

                              Plan of Distribution
                              --------------------

     The  Selling  Stockholders  and  any  of  their  pledgees,   assignees  and
successors-in-interest  may, from time to time,  sell any or all of their shares
of Common Stock on any stock exchange,  market or trading  facility on which the
shares  are traded or in private  transactions.  These  sales may be at fixed or
negotiated  prices.  The  Selling  Stockholders  may  use any one or more of the
following methods when selling shares:

          -    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;

          -    settlement of short sales;

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

          -    a combination of any such methods of sale; and

          -    any other method permitted pursuant to applicable law.

     The  Selling  Stockholders  may also sell  shares  under Rule 144 under the
Securities Act, if available, rather than under 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.

     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 Securities Act of 1933

<PAGE>

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 and any broker-dealers or agents that are involved
in selling the shares may be deemed to be  "underwriters"  within the meaning of
the Securities Act in connection with such sales. In such event, any commissions
received  by such  broker-dealers  or agents and any profit on the resale of the
shares  purchased  by them  may be  deemed  to be  underwriting  commissions  or
discounts under the Securities Act. The Selling  Stockholders  have informed the
Company  that it does not have  any  agreement  or  understanding,  directly  or
indirectly, with any person to distribute the Common Stock.

     The  Company  is  required  to pay all fees and  expenses  incident  to the
registration  of the shares.  The Company  has agreed to  indemnify  the Selling
Stockholders against certain losses, claims, damages and liabilities,  including
liabilities under the Securities Act.
