     notified  (orally  or  in  writing, whichever is earlier) by the Commission
     that  a Registration Statement will not be "reviewed," or is not subject to
     further review, or (iii) prior to the date when such Registration Statement

     Commission  that  such  amendment  is  required in order for a Registration
     Statement  to be declared effective, or (iv) a Registration Statement filed
     or  required  to  be  filed  hereunder  is  not  declared  effective by the
     Commission on or before the Effectiveness Date, or (v) after a Registration
     Statement  is first declared effective by the Commission, it ceases for any
     reason  to  remain  continuously effective as to all Registrable Securities

     or  15  day  period, as applicable, is exceeded being referred to as "Event
     Date"), then in addition to any other rights the Holders may have hereunder

     Holder  pursuant  to  the Purchase Agreement for any Registrable Securities
     then  held by such Holder; and (y) on 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

     of  the  aggregate  purchase  price  paid  by  such  Holder pursuant to the
     Purchase Agreement for any Registrable Securities then held by such Holder.

     Section  in full within seven days after the date payable, the Company will
     pay  interest  thereon  at  a rate of 15% per annum (or such lesser maximum
     amount  that  is  permitted  to  be  paid by applicable law) to the Holder,
     accruing  daily from the date such partial liquidated damages are due until
     such amounts, plus all such interest thereon, are paid in full. The partial
     liquidated  damages  pursuant  to

     provisions  of  the Securities Act and the Exchange Act with respect to the
     disposition  of  all  Registrable  Securities  covered  by the Registration
     Statement  during  the  applicable  period  in accordance with the intended
     methods of disposition by the Holders thereof set forth in the Registration

     authority  during the period of effectiveness of the Registration Statement
     for  amendments  or supplements to the 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 the 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  the Registration Statement

     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 the Registration Statement, Prospectus or other
     documents  so  that,  in  the  case  of  the  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  commercially reasonable efforts to avoid the issuance of,

     effectiveness  of the 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  the  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 requested by such
     Person,  and all exhibits to the extent 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 in connection with resales by the Holder of Registrable
     Securities.  Subject  to  the  terms  of this Agreement, 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,  except  after the giving on any notice
     pursuant  to  Section  3(c).

          (g)     Prior to any resale of Registrable Securities by a Holder, use
     its  commercially  reasonable  efforts  to register or qualify or cooperate
     with  the  selling

                                      --  5
<PAGE>
     Holders  in connection with the registration or qualification (or exemption
     from  the Registration or qualification) of such Registrable Securities for
     the  resale  by  the  Holder  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 to enable the disposition in such
     jurisdictions  of  the  Registrable  Securities covered by the 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)     If  requested  by  the  Holders, cooperate with the Holders to
     facilitate the timely preparation and delivery of certificates representing
     Registrable  Securities  to  be  delivered  to a transferee pursuant to the
     Registration  Statement,  which  certificates  shall be free, to the extent
     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  the  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 the
     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. If the Company
     notifies the Holders in accordance with clauses (ii) through (v) of Section
     3(c)  above  to  suspend  the  use  of  the use of any Prospectus until the
     requisite changes to such Prospectus have been made, then the Holders shall
     suspend  use  of  such Prospectus. The Company will use its best efforts to
     ensure  that  the  use  of  the Prospectus may be resumed as promptly as is
     practicable. The Company shall be entitled to exercise its right under this
     Section  3(i)  to  suspend the availability of a Registration Statement and
     Prospectus,  subject  to  the  payment  of  liquidated  damages pursuant to
     Section  2(b),  for  a  period  not  to  exceed  60 days (which need not be
     consecutive  days)  in  any  12  month  period.

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

     beneficially  owned  by such Holder and, if required by the Commission, the
     person  thereof  that  has  voting and dispositive control over the Shares.
     During  any  periods  that  the  Company  is unable to meet its obligations
     hereunder  with  respect  to the registration of the Registrable Securities
     solely  because  any  Holder fails to furnish such information within three
     Trading  Days  of  the  Company's  request, any liquidated damages that are
     accruing  at such time as to such Holder only shall be tolled and any Event
     that  may  otherwise  occur  solely

                                      --  6

     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 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  the  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  (i)  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

                                      --  7
<PAGE>
     Registrable  Securities  and  was  provided  to  the  Holder  for review in
     accordance  with  Section  3(a)  (it  being  understood that the Holder has
     approved  Annex  A  hereto  for  this  purpose)  or  (ii) 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(d). 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, to the extent 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 the
     Registration  Statement  or  such Prospectus or (ii) 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  provided  to  the  Holder  for review in
     accordance  with  Section  3(a)  (it  being  understood that the Holder has
     approved  Annex A hereto for this purpose), such Prospectus or such form of
     Prospectus  or in any 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(d).  In  no  event  shall the liability of any
     selling Holder hereunder be greater in amount than the dollar amount of the
     net  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

                                      --  8
<PAGE>
     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 reasonably believe that a material
     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.

          Subject  to  the  terms  of  this  Agreement,  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 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

                                      --  9
<PAGE>
     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 this
     Agreement,  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 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)     No  Piggyback  on  Registrations.  The  Company  may  include
                  --------------------------------
     securities  of  the  Company  in  a  Registration  Statement other than the
     Registrable  Securities,  provided  that  the  total  number  of securities
     included  may  not  be  in  excess  of  [130,000]  shares  of  Common Stock
     (including  any  shares  underlying  Common Stock Equivalents). The Company
     shall  not  file any other registration statement until after the Effective
     Date  except  for  registration  statements  on  Form  S-8  to register any
     currently  outstanding  stock  plans.

          (c)     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  the  Registration  Statement.

                                     --  10
<PAGE>
          (d)     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 the 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 will use its best
     efforts to ensure that the use of the Prospectus may be resumed as promptly
     as  it  practicable.  The  Company agrees and acknowledges that any periods
     during  which  the Holder is required to discontinue the disposition of the
     Registrable  Securities  hereunder  shall  be  subject to the provisions of
     Section  2(b).

          (e)     Piggy-Back  Registrations.  If  at  any  time  during  the
                  -------------------------
     Effectiveness  Period  there  is  not  an  effective Registration Statement
     covering  all of the Registrable Securities and the Company shall determine
     to  prepare  and file with the Commission a registration statement relating
     to  an  offering  for  its  own  account or the account of others under the
     Securities  Act  of any of its equity securities, other than on Form S-4 or
     Form  S-8  (each  as  promulgated  under  the Securities Act) or their then
     equivalents relating to equity securities to be issued solely in connection
     with  any  acquisition  of  any  entity  or  business  or equity securities
     issuable  in  connection  with  the  stock option or other employee benefit
     plans,  then the Company shall send to each Holder a written notice of such
     determination  and,  if  within fifteen days after the date of such notice,
     any  such  Holder shall so request in writing, the Company shall include in
     such  registration statement all or any part of such Registrable Securities
     such  Holder  requests  to  be registered, subject to customary underwriter
     cutbacks  applicable  to  all  holders  of  registration  rights.

          (f)     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 each Holder of the then outstanding Registrable Securities.

          (g)     Notices.  Any  and  all  notices  or  other  communications or
                  -------
     deliveries  required or permitted to be provided hereunder shall be made in
     accordance  with  the  provisions  of  the  Purchase  Agreement.

          (h)     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. Each Holder
     may  assign  their  respective  rights  hereunder  in the manner and to the
     Persons  as  permitted  under  the  Purchase  Agreement.

          (i)     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 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

                                     --  11
<PAGE>
     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.

          (j)     Governing  Law.  All  questions  concerning  the construction,
                  --------------
     validity,  enforcement  and  interpretation  of  this  Agreement  shall  be
     determined  with  the  provisions  of  the  Purchase  Agreement.

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

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

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

          (n)     Independent Nature of Purchasers' Obligations and Rights.  The
                  --------------------------------------------------------
     obligations  of  each  Holder  hereunder are several and not joint with the
     obligations  of  any  other  Holder  hereunder,  and  no  Holder  shall  be
     responsible  in any way for the performance of the obligations of any other
     Holder  hereunder.  Nothing  contained  herein or in any other agreement or
     document  delivered  at  any  closing,  and  no  action taken by any Holder
     pursuant  hereto or thereto, shall be deemed to constitute the Holders as a
     partnership,  an  association, a joint venture or any other kind of entity,
     or  create  a presumption that the Holders are in any way acting in concert
     with  respect  to such obligations or the transactions contemplated by this
     Agreement. Each Holder shall be entitled to protect and enforce its rights,
     including  without limitation the rights arising out of this Agreement, and
     it  shall  not  be  necessary  for  any  other  Holder  to  be joined as an
     additional  party  in  any  proceeding  for  such  purpose.

     The  Selling  Stockholders (the "Selling Stockholders") of the common stock
                                      --------------------
("Common  Stock")  of  eLinear,  Inc. (the "Company") 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:

               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;

               applicable  exchange;

          -    privately  negotiated  transactions;

          -    settlement  of  short  sales  entered into after the date of this
               prospectus;

          -    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;

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

          -    any  other  method  permitted  pursuant  to  applicable  law.

     The  Selling  Stockholders  may  also  sell shares under Rule 144 under the
Securities  Act of 1933, as amended (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.  Each  Selling  Stockholder  does  not  expect these commissions and
discounts  relating  to  its  sales of shares to exceed what is customary in the
types  of  transactions  involved.

                                     --  15

     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 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.  Each Selling Stockholder has
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 certain fees and expenses incurred by the
Company  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.

         2.  Piggyback Registrations.
             -----------------------

         (a) Right to Piggyback. Whenever the Company proposes to register any
of its securities under the Securities Act (other than pursuant to (i) a
registration in connection with the issuance of shares by the Company in
connection with a merger, consolidation, exchange offer or the acquisition of
all or substantially all of the assets of the Company or (ii) a registration
solely in connection with the issuance of shares pursuant to the Company's
employee benefit plans) and the registration form to be used may be used for the
registration of Registrable Securities (a "Piggyback Registration"), the Company
will give prompt written notice to all holders of Registrable Securities of its
intention to effect such a registration and will include in such registration
all Registrable Securities with respect to which the Company has received
written requests for inclusion therein within fifteen (15) days after the
receipt of the Company's notice.

         (b) Piggyback Expenses. The Registration Expenses of the holders of
Registrable Securities will be paid by the Company in all Piggyback
Registrations.

         (c) Priority on Primary Registrations. If a Piggyback Registration is
an underwritten primary registration on behalf of the Company, the Company will
include in such registration all Registrable Securities requested to be included
in such registration; provided, however, that if the managing underwriters
advise the Company in writing that in their opinion the number of securities
requested to be included in such registration exceeds the number which can be
sold in such offering without adversely affecting the marketability of the
offering, the Company will include in such registration (i) first, the
securities the Company proposes to sell, (ii) second, the Registrable Securities
(and other securities with pari passu registration rights) requested to be
included in such registration, pro rata among the holders of such Registrable
Securities (and other securities with pari passu registration rights) on the
basis of the number of shares of Registrable Securities (and other securities
with pari passu registration rights) owned by each holder of securities to be
registered in such offering and (iii) third, other securities, if any, requested
to be included in such registration.

         (d) Priority on Secondary Registrations. If a Piggyback Registration is
an underwritten secondary registration on behalf of holders of the Company's
securities, and the managing underwriters advise the Company in writing that in
their opinion the number of securities requested to be included in such
registration exceeds the number which can be sold in such offering without
adversely affecting the marketability of the offering, the Company will include
in such registration (i) first, the securities requested to be included in such
registration by the holders requesting such registration, (ii) second, the
Registrable Securities (and other securities with pari passu registration
rights) requested to be included in such registration, pro rata among the
holders of such Registrable Securities (and other securities with pari passu
registration rights) on the basis of the number of Registrable Securities (and
other securities with pari passu registration rights) owned by each holder of
securities to be registered in such offering, and (iii) third, other securities
requested to be included in such registration not covered by clause (i) above.

not to effect any public sale or distribution (including sales pursuant to Rule
144) of equity securities of the Company, or any securities convertible into or
exchangeable or exercisable for such securities, during the seven days prior to
and the one hundred eighty (180)-day period beginning on the effective date of
any underwritten registration (except as part of such underwritten
registration), unless the underwriters managing the registered public offering
otherwise agree. Each holder of Registrable Securities agrees to enter into an
agreement with the managing underwriters of any underwritten registration in
which Registrable Securities are included to the foregoing effect if required by
the managing underwriters.

                                        2

         4.  Registration Procedures. Whenever the holders of Registrable
Securities have requested that any Registrable Securities be registered pursuant
to this Agreement, the Company will use its best efforts to effect the
registration and the sale of such Registrable Securities in accordance with the
intended method of disposition thereof and pursuant thereto the Company will as
expeditiously as possible:

         (a) Prepare and file with the SEC a registration statement with respect
to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and notify the holders of the
Registrable Securities covered by such registration statement when such
registration statement has been declared effective by the SEC;

         (b) prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection therewith as
may be necessary to keep such registration statement effective for a period of
(x) not less than one hundred eighty (180) days, in the case of Long-Form
Registrations, and (y) two years, in the case of Short-Form Registrations, or
(z) until all Registrable Securities included in such registration statements
are sold, and comply with the provisions of the Securities Act with respect to

owned by such seller;

         (d) use its best efforts to register or qualify such Registrable
Securities under such other securities or blue sky laws of such jurisdictions,
if required in order to permit sale of such Registrable Securities in such
jurisdictions, as any seller reasonably requests and do any and all other acts
and things which may be reasonably necessary or advisable to enable such seller
to consummate the disposition in such jurisdictions of the Registrable
Securities owned by such seller; provided, however, that the Company will not be
required to (i) qualify generally to do business in any jurisdiction where it
would not otherwise be required to qualify but for this subparagraph, (ii)
subject itself to taxation in any such jurisdiction or (iii) consent to general
service of process (i.e., service of process which is not limited solely to
securities law violations) in any such jurisdiction);

         (e) notify each seller of such Registrable Securities, at any time when
a prospectus relating thereto is required to be delivered under the Securities
Act, of the happening of any event as a result of which the prospectus included
in such registration statement contains an untrue statement of a material fact
or omits any fact necessary to make the statements therein not misleading, and,
at the request of any such seller, the Company will promptly prepare a
supplement or amendment to such prospectus so that, as thereafter delivered to
the purchasers of such Registrable Securities, such prospectus will not contain
an untrue statement of a material fact or omit to state any fact necessary to
make the statements therein not misleading;

         (f) cause all such Registrable Securities to be listed on each
securities exchange or quoted or listed on any system operated by The NASDAQ
Stock Market, Inc. on which similar securities issued by the Company are then
quoted or listed, if any;

         (g) provide a transfer agent and registrar for all such Registrable
Securities not later than the effective date of such registration statement;

         (h) otherwise use its best efforts to comply with all applicable rules
and regulations of the SEC;

         (i) in the event of the issuance of any stop order suspending the
effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any common stock included in such registration statement for sale in any
jurisdiction, the Company will promptly notify the holders of Registrable
Securities and will use its reasonable best efforts promptly to obtain the
withdrawal of such order;

         (j) obtain a cold comfort letter from the Company's independent public
accountants in customary form and covering such matters of the type customarily
covered by cold comfort letters in such transactions; and

         (k) obtain a legal opinion from the Company's legal counsel in
customary form and covering such matters of the type customarily covered by
legal opinions given in such transactions.

performance of or compliance with this Agreement, including without limitation,
all registration and filing fees, fees and expenses of compliance with
securities or blue sky laws, printing expenses, messenger and delivery expenses,
and fees and disbursements of counsel for the Company and all independent
certified public accountants, underwriters (excluding discounts and commissions)
and other persons retained by the Company (all such expenses being herein called
"Registration Expenses"), will be borne as provided in this Agreement, and the
expenses and fees for listing the securities to be registered on each securities
exchange on which similar securities issued by the Company are then listed or
fees relating to listing or quotation on any system operated by The NASDAQ Stock
Market, Inc. The Company shall not be required to pay an underwriting discount
with respect to any shares being sold by any party other than the Company in
connection with an underwritten public offering of any of the Company's
securities pursuant to this Agreement.

         6.  Indemnification.
             ---------------

         (a) The Company agrees to indemnify, to the full extent permitted by
law, each holder of Registrable Securities, its partners, officers and directors
and each Person who controls such holder (within the meaning of the Securities
Act) against all losses, claims, damages, liabilities and expenses arising out
of or based upon any untrue or alleged untrue statement of material fact
contained in any registration statement, prospectus or preliminary prospectus or
any amendment thereof or supplement thereto or any omission or alleged omission
of a material fact required to be stated therein or necessary to make the
statements therein not misleading, and shall reimburse such holder, partner,
director, officer or controlling person for any legal or other expenses
reasonably incurred by such holder, partner, officer, director or controlling
person in connection with the investigation or defense of such loss, claim,
damage, liability or expense, except insofar as the same are caused by or
contained in any information furnished in writing to the Company by such holder
expressly for use therein or by such holder's failure to deliver a copy of the
registration statement or prospectus or any amendments or supplements thereto
after the Company has furnished such holder with a sufficient number of copies
of the same. In connection with an underwritten offering, the Company will
indemnify such underwriters, their officers and directors and each Person who
controls such underwriters (within the meaning of the Securities Act) to the
same extent as provided above with respect to the indemnification of the holders
of Registrable Securities.

         (b) In connection with any registration statement in which a holder of
Registrable Securities is participating, each such holder will furnish to the
Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such registration statement or
prospectus and, to the full extent permitted by law, will indemnify the Company,
its directors and officers and each Person who controls the Company (within the
meaning of the Securities Act) against any losses, claims, damages, liabilities
and expenses resulting from any untrue or alleged untrue statement of material
fact contained in the registration statement, prospectus or preliminary
prospectus or any amendment thereof or supplement thereto or any omission or
alleged omission of a material fact required to be stated therein or necessary
to make the statements therein not misleading, but only to the extent that such
untrue statement or omission is contained in any information or affidavit so
furnished by such holder for use in such registration statement or prospectus.

         (c) Any Person entitled to indemnification hereunder will (i) give
prompt written notice to the indemnifying party of any claim with respect to
which it seeks indemnification and (ii) unless in such indemnified party's
reasonable judgment a conflict of interest between such indemnified and
indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. If such defense is assumed, the
indemnifying party will not be subject to any liability for any settlement made
by the indemnified party without its consent (but such consent will not be
unreasonably withheld). An indemnifying party who is not entitled to, or elects
not to, assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable judgment
of any indemnified party a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
claim.

         (d) The indemnification provided for under this Agreement will remain
in full force and effect regardless of any investigation made by or on behalf of
the indemnified party or any officer, director or controlling Person of such
indemnified party and will survive the transfer of securities. The Company and
each holder of Registrable Securities also agree to make such provisions, as are
reasonably requested by any indemnified party, for contribution to such party in
the event that indemnification is unavailable for any reason.

         7.  Participation in Underwritten Registrations. No Person may
participate in any registration hereunder which is underwritten unless such
Person (a) agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Person or Persons entitled hereunder
to approve such arrangements and (b) completes and executes all customary

                                        4
<PAGE>

questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents required under the terms of such underwriting arrangements.

         8.  Rule 144 Reporting. With a view to making available to the holders
of Registrable Securities the benefits of certain rules and regulations of the
SEC which may permit the sale of the Registrable Securities to the public
without registration, the Company agrees to use its best efforts to:

         (a) make and keep current public information available, within the
meaning of Rule 144 or any similar or analogous rule promulgated under the
Securities Act, at all times while it is subject to the reporting requirements
of the Exchange Act;

         (b) file with the SEC, in a timely manner, all reports and other
documents required of the Company under the Securities Act and Exchange Act at
all times during which it is subject to such reporting requirements; and

         (c) so long as any party hereto owns any Registrable Securities,
furnish to such Person forthwith upon request, a written statement by the
Company as to its compliance with the reporting requirements of said Rule 144,
the Securities Act and the Exchange Act, a copy of the most recent annual or
quarterly report of the Company; and such other reports and documents as such
Person may reasonably request in availing itself of any rule or regulation of
the SEC allowing it to sell any such securities without registration.

         9.  Miscellaneous.
             -------------
