         2. Piggyback Registration Rights.

         (a) Right to Piggyback. Subject to the last sentence of this subsection
    (a),  whenever the Company  proposes to register  any Shares (or  securities
    convertible  into or  exchangeable  or  exercisable  for  Shares)  under the
    Securities Act for its own account or for the account of Persons  exercising
    demand  registration  rights other than  pursuant to Section 3 below,  other
    than under a Registration  Statement on Form S-4, Form S-8  or any successor
    form or  filed in  connection  with an  exchange  offer  or an  offering  of
    securities solely to the Company's  existing employees or securityholders (a
    "Piggyback  Registration"),  the Company will give prompt  written notice to
    all Holders of its intention to effect such a Registration  and will use its
    best efforts,  subject to Section 2(b) below,  to include in such  Piggyback
    Registration  all  Registrable  Securities with respect to which the Company
    has received written requests for inclusion  therein within 15 Business Days
    after receipt of the Company's  notice.  Except as may otherwise be provided
    in this Agreement, Registrable Securities with respect to which such request
    for  Registration  has been  received  will be registered by the Company and
    offered to the public on the same terms and  subject to the same  conditions
    applicable to the Piggyback Registration to be sold by the Company or by the
    other Persons selling under such Piggyback Registration. Notwithstanding the
    foregoing,  the Company  shall have the right to  postpone  or withdraw  any
    Registration effected pursuant to this Section 2(a).

         (b) Priority on Piggyback  Registrations.  If a Piggyback  Registration
    relates  to  an  underwritten  offering  and  the  managing  underwriter  or
    underwriters  advise the Company in writing that in its or their opinion the
    number of securities proposed to be sold in a Piggyback Registration exceeds
    the number which can be sold in such offering within a price range

                                       3


    acceptable   to  the  Company  or  the  other  Persons   exercising   demand
    registration rights, the Company will include in such Piggyback Registration
    the  number of  securities  which,  in the  opinion of such  underwriter  or
    underwriters, can be sold within such price range, which securities shall be
    allocated as follows: (x) first, the securities proposed to be sold by other
    Persons  exercising  demand  registration  rights granted on or prior to the
    Closing Date, (y) second,  Registrable  Securities  held by Holders who have
    made requests to be included in such Piggyback  Registration (pro rata among
    the Holders who have requested their  Registrable  Securities to be included
    therein),  together  with any other  securities  requested to be included in
    such Piggyback  Registration by other holders, pro rata among the Holders of
    Registerable Securities to be included therein and the other holders of such
    other  securities  requested to be included in such Piggyback  Registration,
    and (z) third, the securities the Company proposes to sell.

         (c)  Underwriting.  If a Piggyback  Registration  for which the Company
    gives notice is for a registered public offering  involving an underwriting,
    the  Company  shall so advise the  Holders in the notice  given  pursuant to
    Section  2(a),   which  notice  shall  include  the  name  of  the  managing
    underwriter  or  underwriters.  In such  event,  the right of any  Holder to
    Piggyback  Registration pursuant to this Section 2 shall be conditional upon
    such Holder's  participation in such underwriting with respect to all of its
    securities included in such Piggyback Registration.

         3. Demand Registration Rights.

         (a) Right to Demand.  At any time before the  expiration  of five years
    from the date of  original  issuance  of the  Registrable  Securities,  each
    Holder may make one written  request and both  Holders may jointly  make one
    written request (provided in each case no Holder has registered  Registrable
    Securities  pursuant  to  Section  2 above  within  120  days  prior to such
    request) to the Company for  registration  with the Commission  under and in
    accordance with the provisions of the Securities Act of not less than 50% of
    the Registrable  Securities (a "Demand  Registration").  Notwithstanding any
    thing to the contrary contained herein, the Company shall not be required to
    effect more than three  Demand  Registrations  hereunder.  Unless  expressly
    agreed to by the  Holders,  no  securities  of the  Company  or of any other
    Person  other than  Registrable  Securities  shall be  included  in a Demand
    Registration.

         (b) Priority on Demand  Registrations.  If the managing  underwriter or
    underwriters  of  a  Demand  Registration  (or  in  the  case  of  a  Demand
    Registration not being underwritten, the

                                       4


    Holders)  advise the  Company in writing  that in its or their  opinion  the
    number  of  Registrable  Securities  proposed  to be  sold  in  such  Demand
    Registration  exceeds  the number  which can be sold in such  offering,  the
    Company  will  include  in such  Demand  Registration  only  the  number  of
    Registrable  Securities  which,  in  the  opinion  of  such  underwriter  or
    underwriters  (or the  Holders,  as the case  may  be),  can be sold in such
    offering on a pro rata basis.

         (c)  Selection   of  Underwriters.  If any Demand  Registration  is  an
    underwritten  offering,  the Holders will select a managing  underwriter  or
    underwriters  to  administer  the offering  which  managing  underwriter  or
    underwriters  shall  be of  nationally  recognized  standing  and  shall  be
    reasonably acceptable to the Company.

         4.  Registration  Procedures.  With respect to  any  Registration,  the
Company will (subject to Section 11 below) promptly:

         (a) prepare and file with the  Commission a  Registration  Statement (a
    "Registration  Statement") which includes the Registrable Securities and use
    its best efforts to cause such Registration Statement to become effective as
    promptly  as  practicable;   provided  that  before  filing  a  Registration
    Statement  or any  amendments  thereto of any  Prospectus,  the Company will
    furnish to one counsel selected by the Holders of the Registrable Securities
    covered by such Registration  Statement and the underwriters,  if any, draft
    copies of all such  documents  proposed to be filed at least 5 Business Days
    prior thereto,  which documents will be subject to the reasonable  review of
    such  counsel  and   underwriters,   and  the  Company  will  not  file  any
    Registration  Statement  or  amendment  thereto or any  Prospectus  to which
    Holders  of a majority  of the  Registrable  Securities  covered by a Demand
    Registration,  shall  reasonably  object (provided that nothing herein shall
    prevent the Company from making a timely filing of any report required to be
    filed by it pursuant to the  Exchange Act in such form as it  determines  is
    appropriate)  and will notify each Holder of the  Registrable  Securities of
    any  stop  order  issued  or  threatened  by the  Commission  in  connection
    therewith and take all reasonable  actions  required to prevent the entry of
    such stop order or to remove it if entered;

         (b)  prepare  and  file  with  the  Commission   such   amendments  and
    post-effective  amendments to the Registration Statement as may be necessary
    to keep the Registration  Statement  effective for a period of not less than
    four  months  (or  such  shorter   period  which  will  terminate  when  all
    Registrable Securities covered by such Registration Statement have been sold
    or  withdrawn,  but not prior to the  expiration  of any  applicable  period
    referred to in Section 4(3) of the Securities  Act and Rule 174  thereunder,
    if applicable); cause the Prospectus to

                                       5


    be  supplemented  by  any  required   Prospectus   supplement,   and  as  so
    supplemented  to be filed pursuant to Rule 424 under the Securities Act; and
    comply with the  provisions  of the Securities  Act  applicable  to  it with
    respect to the  disposition of all securities  covered by such  Registration
    Statement  during the  applicable  period in  accordance  with the  intended
    methods of disposition by the sellers thereof set forth in such Registration
    Statement or Prospectus supplement;

         (c) furnish to any Holder holding  Registrable  Securities  included in
    such Registration Statement and the underwriter or underwriters,  if any, at
    least one signed copy of the Registration Statement and  any  post-effective
    amendment thereto, upon request, and such number of conformed copies thereof
    and such  number of copies of the  Prospectus  (including  each  preliminary
    Prospectus),  and any documents  incorporated by reference therein,  as such
    Holder or  underwriter  may reasonably  request  in order to facilitate  the
    disposition  of the  Registrable  Securities  being sold by such  Holder (it
    being  understood that the Company  consents to the use of the Prospectus by
    each  Holder  holding  Registrable  Securities  covered by the  Registration
    Statement and the  underwriter or  underwriters,  if any, in connection with
    the  offering  and  sale  of  the  Registrable  Securities  covered  by  the
    Prospectus);

         (d) notify each Holder holding Registrable  Securities included in such
    Registration  Statement,  at any time when a Prospectus  relating thereto is
    required to be delivered  under the Securities Act, when the Company becomes
    aware of the  happening  of any event as a result  of which  the  Prospectus
    included in such  Registration  Statement  (as then in effect)  contains any
    untrue  statement  of a  material  fact or omits to  state a  material  fact
    necessary to make the  statements  therein (in the case of the Prospectus or
    any preliminary  Prospectus,  in light of the circumstances under which they
    were made) not  misleading  and,  as  promptly  as  practicable  thereafter,
    prepare and file with the  Commission  and make  available a  supplement  or
    amendment  to such  Prospectus  so  that,  as  thereafter  delivered  to the
    purchasers of such Registrable Securities,  such Prospectus will not contain
    any untrue  statement  of a  material  fact or omit to state  material  fact
    necessary  to make the  statements  therein,  in light of the  circumstances
    under which they were made, not misleading;

         (e) use its best  efforts  to cause all  Registrable  Securities  to be
    listed,  by the date such  Registrable  Securities  cease to be  Registrable
    Securities  as a result of  Registration  or otherwise,  on each  securities
    exchange on which the Shares are then  listed or  proposed to be listed,  if
    any;


                                       6


         (f) make  generally  available  to its  security  holders  an  earnings
    statement  satisfying  the provisions of Section 11(a) of the Securities Act
    no later than 45 days after the end of the 12-month  period  beginning  with
    the first day of the Company's  first fiscal  quarter  commencing  after the
    effective date of the Registration Statement, which earnings statement shall
    cover said 12-month period;  provided,  however,  that in the event that the
    first  day of the  Company's  first  fiscal  quarter  commencing  after  the
    effective date of the Registration  Statement  shall  also  be the first day
    of the  Company's  fiscal  year,  such  earnings  statement  shall  be  made
    generally  available  no later than 90 days  after the end of such  12-month
    period;

         (g)  use its  best  efforts  to  obtain  the  withdrawal  of any  order
    suspending the  effectiveness of the Registration  Statement at the earliest
    possible moment;

         (h) if requested by the managing  underwriter  or underwriters  or  any
    Holder holding Registrable  Securities covered by the Registration Statement
    promptly incorporate in a Prospectus supplement or post-effective  amendment
    such information as the managing  underwriter or underwriters or such Holder
    requests to be included  therein with  respect to the number of  Registrable
    Securities  being sold by such Holder to such  underwriter or  underwriters,
    the purchase price being paid therefor by such  underwriter or  underwriters
    and with  respect to any other  terms of the  underwritten  offering  of the
    Registrable  Securities to be sold in such  offering;  and promptly make all
    required filings of such Prospectus supplement or post-effective amendment;

         (i) as promptly as practicable  after filing with the Commission of any
    document which is incorporated  by reference into a Registration  Statement,
    deliver  a  copy  of  such  document  to  each  Holder  holding  Registrable
    Securities covered by such Registration Statement;

         (j) on or  prior to the date on which  the  Registration  Statement  is
    declared  effective,  use its best  efforts  to  register  or  qualify,  and
    cooperate with the Holders holding  Registrable  Securities included in such
    Registration Statement,  the  underwriter or underwriters, if any, and their
    counsel,  in  connection  with  the  registration  or  qualification  of the
    Registrable  Securities covered by the Registration  Statement for offer and
    sale  under  the  securities  or  blue  sky  laws of each  state  and  other
    jurisdiction  of  the  United  States  as any  such  Holder  or  underwriter
    reasonably  requests in writing,  to use its best  efforts to keep each such
    registration  or  qualification effective, including through new filings, or
    amendments  or renewals,  during the period such  Registration  Statement is
    required to be kept effective

                                       7


    pursuant  to Section  4(b) hereof and to do any and all other acts or things
    necessary or advisable to permit the disposition in  all  such jurisdictions
    of  the  Registrable  Securities  covered  by  the  applicable  Registration
    Statement;

         (k) cooperate with the Holders holding  Registrable  Securities covered
    by the Registration  Statement and the managing underwriter or underwriters,
    if any, to facilitate the timely  preparation  and delivery of  certificates
    (not bearing any restrictive legends) representing Registrable Securities to
    be sold under the Registration Statement and enable such securities to be in
    such denominations and registered in such names as the managing  underwriter
    or underwriters, if any, or Holders may request;

         (l) use its best efforts to cause the Registrable Securities covered by
    the  Registration  Statement to be registered with or approved by such other
    governmental  agencies  or  authorities  within the United  States as may be
    necessary  to enable  the  Selling  Holders  thereof or the  underwriter  or
    underwriters,  if any, to consummate  the  disposition  of such  Registrable
    Securities;

         (m) enter into such  customary  agreements  (including an  underwriting
    agreement in customary  form) and take all such other actions as the Holders
    of a majority of the Registrable  Securities  being sold or the underwriters
    retained by Holders  participating in an underwritten  public  offering,  if
    any,  reasonably  request in order to expedite or facilitate the disposition
    of such Registrable Securities;

         (n)  make  available  for  inspection  by  any  Holder  of  Registrable
    Securities  included  in  such  Registration  Statement,   any   underwriter
    participating in any disposition  pursuant to such  Registration  Statement,
    and any attorney,  accountant or other agent  retained by any such seller or
    underwriter  (collectively,  the  "Inspectors"),  all  financial  and  other
    records,  pertinent  corporate documents and properties  of  the Company and
    its direct and indirect  subsidiaries  (collectively the "Records") as shall
    be  reasonably  necessary  to enable  them to exercise  their due  diligence
    reasonably,  and cause the  Company's  officers,  directors and employees to
    supply  all  information  reasonably  requested  by any such  Inspectors  in
    connection  with such  Registration  Statement;  provided,  that the Records
    which the Company determines, in good faith, to be confidential and which it
    notifies  the  Inspectors  are  confidential  shall not be  disclosed to the
    Inspectors  unless (x) the  disclosure of such Records is necessary to avoid
    or correct a misstatement or omission in the  Registration  Statement or (y)
    the release of such Records is ordered pursuant to a subpoena or other order
    from a court of competent jurisdiction; provided, however, that any

                                       8


    decision  not to disclose  information  pursuant to clause (x) shall be made
    after  consultation  with  counsel  for the  Company,  and  each  Holder  of
    Registrable  Securities included in such Registration  Statement agrees that
    it will,  upon learning that disclosure of such Records is sought in a court
    of competent jurisdiction, give notice to the Company and allow the Company,
    at the  Company's  expense,  to  undertake  appropriate  action  to  prevent
    disclosure of the Records deemed confidential; and

         (o) use its best  efforts  to  obtain a cold  comfort  letter  from the
    Company's  independent  public accountants and an opinion of outside counsel
    to the Company, each in customary form and covering such matters of the type
    customarily  covered by cold comfort letters or opinions of counsel,  as the
    case may be, as the  Holders of a  majority  of the  Registrable  Securities
    being sold reasonably request.

         Each  Holder,  upon  receipt  of any  notice  from the  Company  of the
happening of any event of the kind  described in Section  4(d),  will  forthwith
discontinue  disposition  of the  Registrable  Securities  until  such  Holders'
receipt of the copies of the supplemented or amended Prospectus  contemplated by
Section  4(d) or until it is advised in writing  (the  "Advice")  by the Company
that the use of the  Prospectus may be resumed,  and has received  copies of any
additional or  supplemental  filings which are  incorporated by reference in the
Prospectus,  and, if so  directed by the  Company,  such  Holder  will,  or will
request the  managing  underwriter  or  underwriters,  if any, to deliver to the
Company  all copies,  other than  permanent  file  copies then in such  Holder's
possession,  of the Prospectus covering such Registrable  Securities at the time
of receipt of such notice.  In the event the Company shall give any such notice,
the time  period  mentioned  in Section  4(b) shall be extended by the number of
Business  Days  during the period from and  including  the date of the giving of
such notice to and including the date when each Selling  Holder  covered by such
Registration  Statement  shall have received the copies of the  supplemented  or
amended Prospectus contemplated by Section 4(d) or the Advice.

         Each Holder shall furnish to the Company such information regarding the
Registrable Securities held by it and the intended method of disposition thereof
and other  information  concerning  the Holder as the Company  shall  reasonably
request and as shall be required in connection with the  Registration  Statement
to be filed by the Company.

         5. Holdback Arrangements.

         (a) Restrictions on Public Sale by Holder of Registrable Securities. To
    the  extent  not  inconsistent   with  applicable  law,  each  Holder  whose
    Registrable  Securities are included in an underwritten  Registration agrees
    not to effect any public

                                       9


    sale  or  distribution  of the  securities  being  registered  or a  similar
    security of the Company, or any securities  convertible into or exchangeable
    or exercisable for such securities, including a sale pursuant to Rule 144 or
    Rule 144A under the Securities  Act, during the 14 days prior to, and during
    and not  exceeding  90 days after the  effective  date of such  Registration
    Statement as may be  reasonably  requested by the  managing  underwriter  or
    underwriters, except as part of such Registration Statement.

         (b) Restrictions on Public Sale by the Company.  The Company agrees (x)
    not to effect any public sale or distribution  of  any securities similar to
    those being registered,  or any securities  convertible into or exchangeable
    or exercisable for such securities (other than any such sale or distribution
    of such  securities  in  connection  with  any   merger   or   consolidation
    involving  the Company or a  subsidiary  thereof or the  acquisition  by the
    Company or a subsidiary  thereof of the capital equity or substantially  all
    of the assets of any other Person or with respect to any employee benefit or
    stock  plan),  during  the 14 days  prior to,  and  during  such  period not
    exceeding 90 days after the  effective  date of any  Registration  Statement
    except as part of such  Registration  Statement;  and (y) that any agreement
    entered into after the date of this Agreement  pursuant to which the Company
    issues or agrees to issue any privately placed  securities (which securities
    shall be  subject  to the  provisions  of  Section  2(b))  shall  contain  a
    provision  under which  holders of such  securities  agree not to effect any
    public  sale or  distribution  of any  such  securities  during  the  period
    described in (x) above, in each case including a sale pursuant to  Rule  144
    or  Rule  144A  under  the  Securities  Act  (except  as  part  of any  such
    registration,  if permitted);  provided, however, that the provision of this
    Section 5(b) shall not prevent the  conversion or exchange of any securities
    pursuant  to their  terms as in  effect  prior to the  commencement  of such
    period into or for other securities.

         (c)  Other  Registrations.  If  the  Company  has  previously  filed  a
    Registration Statement with respect to Registrable  Securities,  and if such
    previous registration has not been withdrawn or abandoned,  the Company will
    not file or cause  to be  effective  any  other  registration  of any of the
    Shares (or securities  convertible  into or  exchangeable or exercisable for
    the  Shares)  under the  Securities  Act  (except on Form S-4 or S-8 or  any
    successor forms or filed in connection with an exchange after or an offering
    of  securities  solely  to the  Company's  existing  employees  or  security
    holders),  whether on its own or at the  request of any holder or holders of
    the Shares (or securities  convertible  into or  exchangeable or exercisable
    for the  Shares),  until a period of at least 120 days has elapsed  from the
    effective date of such previous registration (provided that in the case of a
    Demand

                                       10


    Registration  such  period  shall  commence on the date the Company is first
    served the notice of demand  registration  and shall continue until at least
    ninety  (90)  days  have  elapsed  from the  effective  date of such  Demand
    Registration).

         6. Indemnification; Contribution.

         (a) Indemnification by the Company. The Company agrees to indemnify and
    hold harmless each Selling Holder of Registrable Securities,  its  officers,
    directors  and agents and each  Person,  if any,  who  controls  such Holder
    within the meaning of Section 15 of the  Securities Act or Section 20 of the
    Exchange  Act (each an  "Indemnitee")  from and  against any and all losses,
    claims,  damages,  liabilities and expenses (including reasonable attorneys'
    fees and costs of  investigation)  arising  out of or based  upon any untrue
    statement or alleged  untrue  statement of a material fact  contained in any
    Registration  Statement or  Prospectus,  or arising out of or based upon any
    omission or alleged omission to state therein a material fact required to be
    stated therein or necessary to make the statements  therein not  misleading,
    except  insofar as such losses,  claims,  damages,  liabilities  or expenses
    arise out of or are based upon  information  with respect to such Indemnitee
    furnished  in writing to the Company by such  Indemnitee  expressly  for use
    therein. It is agreed that the indemnification  agreement  contained in this
    Section 6(a) shall not apply to amounts paid in settlement of any such loss,
    claim,  damage or  liability  if such  settlement  is  effected  without the
    consent of the Company  (which consent has not  been unreasonably  withheld.
    The Company also agrees to indemnify any underwriters on  substantially  the
    same basis as that of the indemnification of the Selling Holders provided in
    this Section 6(a).

         (b) Conduct of Indemnification Proceedings. If any action or proceeding
    (including any  governmental  investigation)  shall  be  brought or asserted
    against any Selling  Holder (or its  officers,  directors  or agents) or any
    Person  controlling  any  such Selling Holder in respect of which  indemnity
    may be sought from the Company, the Company shall be permitted to assume the
    defense of such claim,  unless in the reasonable judgment of such Indemnitee
    a conflict of interest  may exist  between such  Indemnitee  and the Company
    with  respect to such  claim or  differing  or  additional  defenses  may be
    available  to such  Indemnitee.  If  defense  of a claim is  assumed  by the
    Company,  Indemnitees  shall not be liable for any settlement of such action
    or proceedings  effected  without their prior written  consent.  The Company
    will not consent to entry of any judgment or enter into any settlement which
    does not include as an unconditional term thereof the giving by the claimant
    or plaintiff to such  Indemnitee  of a release from all liability in respect
    of such claim or litigation. If the Company is not

                                       11


    entitled to, or elects not to, assume the defense of a claim, it will not be
    obligated  to pay the fees and  expenses  of more than one  counsel  for the
    Indemnitees  as a group with respect to such claim in each  jurisdiction  in
    which  a  claim  is  brought,  unless  in  the  reasonable  judgment  of any
    Indemnitee a conflict of interest may exist between such  Indemnitee and any
    other  Indemnitee  with  respect to such claim or  differing  or  additional
    defense  may be  available  to such  Indemnitee,  in which event the Company
    shall be obligated to pay the fees and expenses of such  additional  counsel
    or counsels. Any Selling Holder entitled to indemnification hereunder agrees
    to give  prompt  written  notice to the  Company  after the  receipt by such
    Selling  Holder of any  written  notice of the  commencement  of any action,
    suit,  proceedings  or  investigation  or threat thereof made in writing for
    which such Selling Holder may claim indemnification or contribution pursuant
    to this Agreement; provided, however, that failure to give such notice shall
    not  limit  the  Indemnitee's   right  to  indemnification  or  contribution
    hereunder  unless and to the extent that the Company did not otherwise learn
    of  such  action  and  such  failure  results  in  the  forfeiture  by it of
    substantial rights and defenses.

         (c) Indemnification by Holders of Registrable Securities.  Each Selling
    Holder  agrees to indemnify  and hold  harmless  the Company,  and the other
    Selling Holders and each of their respective directors,  officers and agents
    and each  Person,  if any,  who  controls  the Company or any other  Selling
    Holder  within the meaning of either  Section 15 of the  Securities  Act  or
    Section 20 of the Exchange Act to the same extent as the foregoing indemnity
    from the Company to such Selling Holder but only with respect to information
    furnished  in writing by such  Selling  Holder with  respect to such Selling
    Holder  which  contained  a material  misstatement  of fact or omission of a
    material  fact  expressly  for use in any Registration   Statement   or  any
    amendment thereto or any Prospectus,  or any preliminary Prospectus relating
    to the  Registrable  Securities.  In case any action or proceeding  shall be
    brought  against  the  Company,  any  other  Selling  Holder or any of their
    respective directors, officers or agents, or any such controlling Person, in
    respect of which indemnity may be sought against such Selling  Holder,  such
    Selling  Holder shall have the rights and duties  given to the Company,  and
    the  Company,  each  other  Selling  Holder  or  each  of  their  respective
    directors,  officers,  or agents or such  controlling  Person shall have the
    rights and duties given to such Selling Holder, by Section 6(b).

         (d) Contribution. If the indemnification provided for in this Section 6
    is unavailable to the Company,  the Selling  Holders or the  underwriters in
    respect to any losses, claims, damages, liabilities or judgments referred to
    herein, then

                                       12


    each such  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, claims, damages, liabilities and judgments
    in such  proportion as is  appropriate  to reflect the relative fault of the
    indemnifying  parties  and  indemnified  parties  in  connection  with  such
    statements  or  omissions  which  resulted in the losses,  claims,  damages,
    liabilities  or  judgments,   as  well  as  any  other  relevant   equitable
    considerations.   The  relative  fault  of  such   indemnifying   party  and
    indemnified parties shall be determined by reference to, among other things,
    whether the untrue or alleged  untrue  statement  of a material  fact or the
    omission  of  alleged   omissions  to  state  a  material  fact  relates  to
    information  supplied  by such  party,  and the  parties'  relative  intent,
    knowledge,  access to  information  and opportunity  to  correct  or prevent
    such statement or omission.

         The Company and the Selling Holders agree that it would not be just and
    equitable if  contribution  pursuant to this Section 6(d) were determined by
    pro rata allocation or by any other method of allocation which does not take
    account  of the  equitable  considerations  referred  to in the  immediately
    preceding paragraph. The amount paid or payable by an indemnified party as a
    result of the losses, claims, damages, liabilities, or judgments referred to
    in the immediately  preceding paragraph shall be deemed to include,  subject
    to the  limitation set forth above,  any legal or other expenses  reasonably
    incurred by such  indemnified  party in  connection  with  investigating  or
    defending  any  such  action  or  claim.  No  Person  guilty  of  fraudulent
    misrepresentations  (within the meaning of Section  11(f) of the  Securities
    Act) shall be entitled to contribution from any Person who was not guilty of
    such fraudulent  misrepresentations.  For the purposes of this Section 6(d),
    each  director of the  Company,  each  officer  who signed the  Registration
    Statement  and each Person,  if any,  who  controls  the Company  within the
    meaning of Section 15 of the  Securities  Act shall have the same  rights to
    contribution as the Company.

         7.   Participation  in  Underwritten   Registrations.   No  Holder  may
participate in any underwritten Registration hereunder (which shall be conducted
in accordance  with the  provisions of Section 2(b) or 3) unless such Holder (i)
agrees to sell such Holder's Registrable Securities on the basis provided in any
underwriting  arrangements  (approved  by the  applicable  Holders  as  provided
herein) and (ii) completes and executes all questionnaires, powers of attorneys,
underwriting  agreements and other documents reasonably required under the terms
of such underwriting arrangements and these registration rights.

         8. Rule  144.  The  Company  covenants  that it will  file any  reports
required to be filed by it under the Securities Act and

                                       13


the  Exchange  Act and the  rules  and  regulations  adopted  by the  Commission
thereunder  (or, if the Company is not required to file such  reports,  it will,
upon the request of the Holders,  make publicly  available other  information so
long as necessary to permit sales under Rule 144 under the Securities Act), that
it will take such further action as the Holders may reasonably  request,  all to
the extent  required  from time to time to enable  Holders  to sell  Registrable
Securities without  registration under the Securities Act within the limitations
of the  exemptions  provided by (i) Rule 144 under the  Securities  Act, as such
rule may be amended form time to time,  or (ii) any similar  rule or  regulation
hereafter adopted by the Commission. Upon the request of any Holder, the Company
will  deliver to such Holder a written  statement  as to whether it has complied
with the requirements of this Section 8.

         9. Other Registration Rights. Except for registration rights granted to
other  Persons on or prior to the Closing  Date,  the Company will not grant any
Person any demand or  piggyback  registration  rights with respect to the Shares
(or securities convertible into or exchangeable or exercisable for Shares) other
than registration  rights ("new rights") that (i) would not be inconsistent with
the terms of this  Section 9 and (ii) do not  provide  that the  Holders  have a
piggyback  right upon the  exercise  of such new rights and shall be included in
the  registration  statement  and on an equal  basis with the  securities  being
registered pursuant to the exercise of the new rights.

         10.  Registration  Expenses.  The Registration  Expenses related to any
Demand  Registration  or  Piggyback  Registration  shall be borne  solely by the
Company.

         11. Stand-Off and Special Audit.

         (a) Stand-Off.  If at the time of any request for a Demand Registration
    pursuant  to Section  3, the  Company  (i) is engaged or has fixed  plans to
    engage,  within 30 days of the time of the request,  in a registered  public
    offering as to which the  Holders  may,  pursuant to Section 2,  include all
    Registrable  Securities  proposed  to be sold by  them,  and  which  in fact
    becomes  effective  within 90 days after the request,  or (ii) is engaged in
    any other activity which, in the good faith  determination  of the Company's
    board of directors,  would be adversely affected by the Demand  Registration
    to the material detriment of the Company, then the Company may at its option
    direct  that such  request be delayed  for a period not to exceed six months
    from the effective date of such offering or the date of commencement of such
    other material activity, as the case may be.

         (b) Provisions for Special Audit.  In the event that a special audit of
    the  Company's   financial   statements   would  be  required  to  effect  a
    Registration pursuant to Section 3, the

                                       14


    Company shall promptly notify the Holders  requesting  Registration  that  a
    special  audit is required.  In such event,  the Holders who  initiated  the
    Demand Registration shall have the right to either (i) withdraw such request
    for  Registration,  in which  case the  request  shall not count as a Demand
    Registration  to  which  the Holders are  entitled  under this  Agreement or
    (ii) pay the expenses of conducting the special audit.

         12. Public Trading  Market.  Until the earlier of (a) three years after
the date  hereof or (b) the date on which there are no  Registrable  Securities,
the Company shall use its best efforts to maintain a public  trading  market for
its Shares.

         13.  Restriction  on Resale.  Unless  otherwise  agreed by the Company,
until the  earlier of (a) three  years  after the date hereof or (b) the date on
which there are no  Registrable  Securities,  the  Holders  will  not resell the
Registrable Securities without registration under the Securities Act, compliance
with Rule 144,  or an opinion  of  counsel  for such  holder,  addressed  to the
Company, to the effect that no such registration is required.

         14. Miscellaneous.

         (a) Amendments and Waivers.  This Agreement may not be amended  without
    the written consent of the parties hereto.

         (b)  Successors  and  Assigns.  The Holder  shall not assign any of its
    rights or obligations  under this  Agreement  except to (i) an Affiliate (as
    such term is defined in Section 1.01 of the Credit  Agreement) of the Holder
    or (ii) anyone who purchases at least 40,000 of the  Registrable  Securities
    from the Holder prior to the filing of a Registration  Statement pursuant to
    Section 2 or 3 hereof.  This Agreement shall be binding upon and shall inure
    to the benefit of the parties  hereto and their  respective  successors  and
    permitted assigns. No other person shall acquire or have any rights under or
    by virtue of this Agreement.

         (c)  Notices.  All  notices  and  other  communications   provided  for
    hereunder  shall be given and shall be  effective  as provided in the Credit
    Agreement.

         (d)  Descriptive  Headings.  The  headings  in this Agreement  are  for
    convenience  of reference  only and shall not limit or otherwise  effect the
    meaning of terms contained herein.

         (e) Severability.  In the event that any one or more of the provisions,
    paragraphs,  words,  clauses,  phrases or sentences contained herein, or the
    application  thereof  in any  circumstances,  is held  invalid,  illegal  or
    unenforceable  in any respect for any reason,  the  validity,  legality  and
    enforceability of such provision, paragraph, word, clause,

                                      15


    phrase or sentence in every other respect and of the  remaining  provisions,
    paragraphs,  words, clauses, phrases or sentences hereof shall not be in any
    way impaired,  it being  intended that all rights,  powers and privileges of
    the parties hereto shall be  enforceable to the fullest extent  permitted by
    law.

         (f)  Counterparts.  This  Agreement  may be  executed  in  two or  more
    counterparts,  each of which shall be deemed an  original,  but all of which
    shall constitute one and the same instrument,  and it shall not be necessary
    in making  proof of this  Agreement  to produce or account for more than one
    such counterpart.

         (g) Governing  Law. This  Agreement  shall be governed by and construed
    and enforced in accordance with the laws of the State of New York.

         (h) Remedies.  The Company  acknowledges that monetary damages will not
    be adequate  compensation  for any loss incurred by reason of a breach by it
    of the provisions hereof and agrees, to the fullest extent permitted by law,
    to waive the  defense  of  adequacy  of legal  remedies  in any  action  for
    specific performance hereof.

         (i) Merger,  etc. If,  directly or  indirectly,  (i) the Company  shall
    merge with and into, or consolidate with, any other Person,  (ii) any Person
    shall merge with and into, or consolidate  with, the Company and the Company
    shall be the surviving  corporation of such merger or consolidation  and, in
    connection with such merger or consolidation, all or part of the Registrable
    Securities  shall be changed into or exchanged for stock or other securities
    of any other Person, then, in each such case, proper provision shall be made
    so that such Person shall be bound by the  provisions of this  Agreement and
    the term "Company" shall thereafter be deemed to refer to such Person.

         (j) Other  Agreements.  The Company  shall not enter into any agreement
    inconsistent with any of the provisions hereof.

         IN WITNESS  WHEREOF,  each of the undersigned has caused this Agreement
to be executed on its behalf as of the date first written above.
