this Section 2.2(i) or a Demand  Registration  Statement pursuant to Section 2.1
shall have been declared effective by the Commission; and provided further, that
no request  for a  registration  shall be made  unless the  minimum  anticipated
offering  price of the  Registrable  Securities  requested to be included in the
Shelf   Registration,   before  underwriting   discounts  and  commissions,   is
$25,000,000,  or more. Any request made pursuant to this Section 2.2(i) shall be
addressed to the attention of the Company Notice Parties,  and shall specify the
number of  Registrable  Securities  to be  registered,  the intended  methods of
disposition thereof and that the request is for a Shelf Registration pursuant to

more Holders (the "Demanding Takedown Holders") shall be entitled to request the

Supplement")  with respect thereto to effect a takedown for an offering of Notes
registered thereby; provided,  however, that after November 30, 2002, no request
may be made pursuant to this Section  2.2(ii) if within four (4) months prior to
the date of such  request the Company  has filed a Shelf  Prospectus  Supplement
pursuant to this Section 2.2(ii) or a Demand Registration  Statement pursuant to
Section 2.1 shall have been declared  effective by the Commission;  and provided
further,  that no  request  for a  takedown  shall be made  unless  the  minimum
anticipated  offering  price  of  the  Registrable  Securities  requested  to be
included in the Shelf Prospectus  Supplement,  before underwriting discounts and
commissions,  is $25,000,000, or more. Any request made pursuant to this Section
2.2(ii) shall be addressed to the attention of the Company Notice  Parties,  and
shall specify the number of Registrable  Securities to be offered,  the intended
methods of  disposition  thereof and that the request is for a Shelf  Prospectus
Supplement pursuant to this Section 2.2(ii).

     (iii) After  November 30, 2002,  the Company  shall be entitled to postpone
for up to 120 days the  filing of any  Shelf  Registration  Statement  otherwise
required to be prepared and filed pursuant to Section 2.2(i),  and the filing of
any  Shelf  Prospectus  Supplement  for a  takedown  thereunder  required  to be
prepared and filed pursuant to Section 2.2(ii), if the Company determines in its
reasonable  judgment  that such  registration  or  takedown  or the  Transfer of
Registrable  Securities  contemplated  thereby would  interfere with, or require
premature  disclosure of, any financing,  acquisition,  reorganization  or other
matter  involving the Company or any of its Affiliates and the Company  promptly
gives the Demanding  Shelf Holders or the Demanding  Takedown  Holders notice of
such  determination.  Notwithstanding  anything in this Section  2.2(iii) to the
contrary,  there  shall be no more than two delay  periods  pursuant  to Section
2.1(ii) and/or this Section  2.2(iii)  during any  consecutive  12-month  period

     2.3.  Following  receipt of a request for a Demand  Registration or a Shelf
Registration, the Company shall:

     (i) File the  registration  statement  with the  Commission  as promptly as
practicable, and shall use the Company's commercially reasonable efforts to have
the  registration  declared  effective  under  the  Securities  Act as  soon  as
reasonably  practicable,  in each  instance  giving  due  regard  to the need to
prepare current financial  statements,  conduct due diligence and complete other
actions that are reasonably necessary to effect a registered public offering.

     (ii) Use the Company's commercially reasonable efforts to keep the relevant
registration statement Continuously Effective (x) if a Demand Registration,  for
up to 90  days or  until  such  earlier  date as of  which  all the  Registrable
Securities under the Demand  Registration  statement shall have been disposed of
in the  manner  described  in the  Registration  Statement,  and  (y) if a Shelf
Registration,  for two years  and,  with  respect to any  takedown  from a Shelf
Registration  Statement,  the  Shelf  Prospectus  Supplement  relating  to  such
takedown shall be available for use for up to 90 days or until such earlier date
as  of  which  all  the  Registrable  Securities  under  such  Shelf  Prospectus
Supplement  shall  have  been  disposed  of in  the  manner  described  therein.
Notwithstanding  the  foregoing,  if  for  any  reason  the  effectiveness  of a
registration pursuant to this Section 2 is suspended or, in the case of a Demand
Registration,  postponed as permitted by Section  2.1(ii),  the foregoing period
shall  be  extended  by the  aggregate  number  of days of  such  suspension  or
postponement.

     2.4.  The  Company  shall be  obligated  to effect no more than two  Demand
Registrations  and  two  Shelf  Registrations.  For  purposes  of the  preceding
sentence,  registration  shall not be deemed to have been  effected (i) unless a
registration  statement  with  respect  thereto has become  effective or (ii) if
after such registration statement has become effective, such registration or the
related offer,  sale or  distribution  of Registrable  Securities  thereunder is
interfered  with by any stop order,  injunction or other order or requirement of
the  Commission  or other  governmental  agency  or  court  for any  reason  not
attributable  to the Selling  Holders and such  interference  is not  thereafter
eliminated.  If the Company shall have complied with its obligations  under this
Agreement,  a right to demand a registration pursuant to this Section 2 shall be
deemed to have been satisfied (i) if a Demand Registration,  upon the earlier of
(x) the date as of which  all of the  Registrable  Securities  included  therein
shall have been disposed of pursuant to the Registration Statement,  and (y) the
date as of which such Demand Registration shall have been Continuously Effective
for a period of 90 days,  and (ii) if a Shelf  Registration,  upon the effective
date of a Shelf  Registration,  provided  no stop  order or  similar  order,  or
proceedings for such an order, is thereafter entered or initiated.

     2.5. A registration  pursuant to Section 2.1 or 2.2 shall be on Form S-3 or
any successor form.

     2.6. If any  registration  pursuant  to Section 2 involves an  underwritten
offering (whether on a "firm",  "best efforts" or "all reasonable efforts" basis
or otherwise),  or an agented offering,  the Majority Selling Holders shall have
the right to select one or more Underwriters and  Underwriters'  Representatives
to administer such underwritten offering or the Agents for such agented offering
from the list of investment banking firms listed on Schedule 2.6 hereto, as such
schedule may be amended by the Holders that own an aggregate of 51% or more

                                       -7-


in aggregate principal amount of the Registrable Securities then outstanding, on
the one hand, and the Company,  on the other hand.  Each such Person so selected
shall be reasonably acceptable to the Company.

Parties in writing at least 20 days prior to the  commencement of such offering;
and  provided,  further,  that the Company  shall be  entitled  to require  such
Holders to postpone  any such  offering  for up to 120 days after the receipt of
such notice,  if the Company  determines  in its  reasonable  judgment that such
registration  or the Transfer of  Registrable  Securities  contemplated  thereby
would  interfere  with,  or require  premature  disclosure  of,  any  financing,
acquisition,  reorganization or other matter involving the Company or any of its
Affiliates  and  the  Company   promptly  gives  such  Holders  notice  of  such
determination.  Notwithstanding  anything to the contrary to this Agreement, the
Company  shall have no  obligation  to register  or assist in the  registration,
structuring or offering of or to pay any costs or expenses  related to any trust
securities or any other securities that are not Registrable Securities.

exchange,  the name  (including any variation) and logo of the Company or any of
its Affiliates may not be used without the express prior written  consent of the
Company or its applicable Affiliate;  provided, however, that such consent shall
not  be  required  in  connection  with  any  offering   pursuant  to  a  Demand
Registration Statement or Shelf Registration Statement filed with the Commission
pursuant to Section 2.1 or 2.2.



                                      -8-

     3.3. Holder hereby represents, warrants and covenants with the Company that
the Holder has made its own investment  decision and relied on the advice of its
own advisors  with  respect to all matters  relating to the  possibility  of any
pass-through  or similar  securities and that neither the Company nor any of its
officers,  employees, agents or other representatives has provided advice to the
Holder or any of its Members with respect to any such matters.

  Section 4.  Registration  Procedures.  Whenever  required  under  Section 2 or
Section 3 to effect the registration of any Registrable Securities,  the Company
shall, as expeditiously as practicable:

     4.1.  Prepare and file with the  Commission a  registration  statement with
respect  to such  Registrable  Securities  and use  the  Company's  commercially
reasonable  efforts to cause such  registration  statement to become  effective;
provided,  however, that before filing a registration statement or prospectus or
any amendments or  supplements  thereto,  including  documents  incorporated  by
reference  after the initial filing of the  registration  statement and prior to
effectiveness  thereof, the Company shall furnish to one firm of counsel for the
Selling  Holders  (selected  by  Majority  Selling  Holders)  copies of all such
documents in the form  substantially as proposed to be filed with the Commission
at least ten (10)  business  days prior to filing for review and comment by such
counsel, which opportunity to comment shall include an absolute right to control
or contest disclosure if the applicable Selling Holder reasonably  believes that
it may be subject to controlling  person liability under  applicable  securities
laws with respect thereto.

     4.2.  Prepare and file with the Commission  such amendments and supplements
to such  registration  statement and the prospectus used in connection with such
registration  statement as may be necessary to comply with the provisions of the
Securities  Act,  the  Exchange Act and rules and  regulations  thereunder  with
respect  to the  disposition  of all  securities  covered  by such  registration
statement  in  accordance  with the  method  of  disposition  set  forth in such
registration statement. If the registration is for an underwritten offering, the
Company  shall amend the  registration  statement or supplement  the  prospectus
whenever reasonably required by the terms of the underwriting  agreement entered
into pursuant to Section 5.2.  Subject to Rule 415 under the Securities  Act, if
the registration statement is a Shelf Registration,  the Company shall amend the
registration  statement  or  supplement  the  prospectus  so that it will remain
current and in compliance  with the  requirements  of the Securities Act for two
years after its effective  date. If any event or development  occurs as a result
of which a  registration  statement or  prospectus  with respect to  Registrable
Securities  contains  a  misstatement  of a  material  fact or  omits to state a
material fact required to be stated  therein or necessary to make the statements
therein not  misleading,  the Company shall promptly notify each Selling Holder,
amend the registration  statement or supplement the prospectus so that each will
thereafter  comply with the Securities Act and furnish to each Selling Holder of
Registrable Securities such amended or supplemented prospectus,  which each such
Selling Holder shall  thereafter  use in the Transfer of Registrable  Securities
covered by such  registration  statement.  Pending such amendment or supplement,
each such Selling  Holder shall cease making offers or Transfers of  Registrable
Securities  pursuant to the prior prospectus.  In the event that any Registrable
Securities included in a registration statement subject to, or required by, this
Agreement  remain  unsold at the end of the period  during  which the Company is
obligated  to  use  its   commercially   reasonable   efforts  to  maintain  the
effectiveness  of  such   registration   statement,

                                       -9-


the Company may file a post-effective  amendment to the  registration  statement
for the purpose of removing such securities from registered status.

     4.3. Furnish to each Selling Holder of Registrable  Securities such numbers
of copies of the registration  statement,  any  pre-effective or  post-effective
amendment thereto, the prospectus, including each preliminary prospectus and any
amendments  or  supplements  thereto,  in  each  case  in  conformity  with  the
requirements  of the  Securities  Act and the rules  thereunder,  and such other
related documents as any such Selling Holder may reasonably  request in order to
facilitate  the  disposition  of  Registrable  Securities  owned by such Selling
Holder.

     4.4. Use the Company's commercially  reasonable efforts (i) to register and
qualify the Registerable Securities covered by such registration statement under
such other  securities or Blue Sky laws of such states or U.S.  jurisdictions as
shall be reasonably  requested by the Underwriters'  Representative or Agent (as
applicable, or if inapplicable, the Majority Selling Holders), (ii) to keep such
registration  or  qualification  in  effect  for so long  as  such  registration
statement  remains in effect,  and (iii) to obtain the  withdrawal  of any order
suspending the effectiveness of a registration  statement, or the lifting of any
suspension of the qualification  (or exemption from  qualification) of the offer
and transfer of any of the Registrable  Securities in any  jurisdiction,  at the
earliest  possible  moment;  provided,  however,  that the Company  shall not be
required in  connection  therewith  or as a  condition  thereto to qualify to do
business  or to file a general  consent to service of process in any such states
or jurisdictions.

     4.5. In the event of any  underwritten or agented  offering,  in connection
any offering pursuant to a Demand  Registration  Statement or Shelf Registration
Statement  filed with the Commission  pursuant to Section 2.1 or 2.2, enter into
and perform the Company's  obligations under an underwriting or agency agreement
(including  indemnification  and  contribution  obligations of  underwriters  or
agents),  in  usual  and  customary  form,  with  the  managing  underwriter  or
underwriters of or agents for such offering,  and (i) make such  representations
and warranties to the Underwriters'  Representative or Agent with respect to the
business of the Company and its  subsidiaries,  the  registration  statement  or
prospectus,  in each case, in form,  substance and scope as are customarily made
by issuers to underwriters in underwritten offerings and confirm the same if and
when  requested  and (ii)  deliver such  documents  and  certificates  as may be
reasonably   requested  by  the  Selling  Holder,  its  counsel,   Underwriters'
Representative  or Agent,  if any, to  evidence  the  continued  validity of the
representations and warranties of the Company and its subsidiaries made pursuant
to clause (i) above and to evidence  compliance  with any  customary  conditions
contained in the underwriting agreement or similar agreement entered into by the
Company.  The foregoing  actions shall be taken in connection  with each closing
under such  underwriting  or  similar  agreement  as and to the extent  required
thereunder.  The Company shall also cooperate with the Majority  Selling Holders
and the Underwriters' Representative or Agent for such offering in the marketing
of the Registrable  Securities,  including making  available,  on a commercially
reasonable basis, the Company's officers, accountants,  counsel, premises, books
and records for such purpose, but the Company shall not be required to incur any
material out-of-pocket expense pursuant to this sentence.

                                      -10-


     4.6. In the event of any  underwritten or agented  offering,  in connection
with  any  offering  pursuant  to  a  Demand  Registration  Statement  or  Shelf
Registration Statement filed with the Commission pursuant to Section 2.1 or 2.2,
the  Company  and  members of its  management  (which  shall  include  the Chief
Executive  Officer and the Chief Financial  Officer or such other members of its
management  acceptable to the  Underwriters'  Representative  or Agent,  if any)
shall  participate  in  roadshows  and  other  similar  selling  efforts  as the
Underwriters'  Representative  or Agent,  if any,  shall  reasonably  deem to be
necessary;  provided,  however,  the Company and members of its management shall
not be obligated to participate in more than a total of three roadshows or other
similar selling efforts pursuant to this Section 4.6.

     4.7.  Promptly  notify  each  Selling  Holder of any stop  order  issued or
threatened  to be issued by the  Commission in  connection  therewith  (and take
commercially reasonable actions required to prevent the entry of such stop order
or to remove it if entered).

     4.8. Make generally  available to the Company's  security holders copies of
all periodic  reports,  proxy statements,  and other information  referred to in
Section 10.1 and an earnings  statement  satisfying  the  provisions  of Section
11(a) of the  Securities  Act no  later  than 90 days  following  the end of the
12-month  period  beginning  with the first month of the Company's  first fiscal
quarter commencing after the effective date of each registration statement filed
pursuant to this Agreement.

     4.9. Make available for inspection by any Selling  Holder,  any underwriter
participating  in such offering and the  representatives  of such Selling Holder
and Underwriter (but not more than one firm of counsel to such Selling Holders),
all financial and other  information  as shall be reasonably  requested by them,
and provide the Selling Holder,  any Underwriter  participating in such offering
and the  representatives of such Selling Holder and Underwriter the opportunity,
on a  commercially  reasonable  basis,  to discuss the  business  affairs of the
Company with appropriate  officers and independent  public  accountants who have
certified  the  audited  financial  statements  included  in  such  registration
statement,  in each case all as necessary  to enable them to exercise  their due
diligence  responsibility under the Securities Act; provided,  however, that any
records,  information  or  documents  that  are  designated  by the  Company  as
confidential  at the time of delivery of such records,  information or documents
shall be kept confidential by such Persons unless (i) such records,  information
or documents are in the public  domain or otherwise  publicly  available  (other
than by reason of breach of this confidentiality  provision), (ii) disclosure of
such records,  information  or documents is required by court or  administrative
order or is necessary to respond to inquires of regulatory authorities, or (iii)
disclosure of such records,  information or documents, in the reasonable opinion
of counsel to such Person, is otherwise required by law or regulation (including
without  limitation  pursuant  to  the  requirements  of the  Securities  Act or
regulations  promulgated  thereunder);  provided,  however,  that in the case of
subsections  (ii) and (iii) hereof,  prior to making such  disclosure the Holder
shall  consult  with the  Company and its  counsel as to the  necessity  of such
disclosure, the timing and content of such disclosure and the nature and wording
of such disclosure and shall use its reasonable  best efforts to obtain,  at the
Company's  expense,  confidential  treatment  of such  records,  information  or
documents,  or portions thereof. Also, to the extent possible, the Company shall
be given a reasonable opportunity to intervene with the appropriate  authorities
in order to prevent  disclosure of such records,  information  or documents,  or
portions thereof.

                                      -11-


     4.10.  Use the  Company's  commercially  reasonable  efforts  to  obtain  a
so-called  "comfort letter" from its independent public  accountants,  and legal
opinions  of  counsel  to the  Company  addressed  to the  Selling  Holders,  or
Underwriters'  Representative  or Agent,  as  applicable,  in customary form and
covering such matters of the type customarily covered by such letters,  and in a
form that  shall be  reasonably  satisfactory  to  Majority  Selling  Holders or
Underwriters'  Representative or Agent, as applicable. The Company shall furnish
to each Selling Holder a signed  counterpart of any such comfort letter or legal
opinion.  Delivery of any such opinion or comfort letter shall be subject to the
recipient  furnishing such written  representations or  acknowledgements  as are
customarily  provided by sellers of securities who receive such comfort  letters
or opinions.

     4.11. Provide and cause to be maintained  (including the payment of fees in
connection   therewith)  a  trustee,   transfer  agent  and  registrar  for  all
Registrable  Securities covered by such registration  statement from and after a
date not later than the effective date of such registration statement.

     4.12.  Use  commercially   reasonable  efforts  to  cause  the  Registrable
Securities  covered by such  registration  statement (i) to be listed on the New
York Stock Exchange or American  Stock Exchange for a reasonable  period of time
after the  offering,  and (ii) to be  registered  with or approved by such other
United States or state governmental  agencies or authorities as may be necessary
by virtue of the  business and  operations  of the Company to enable the Selling
Holders  of  Registrable  Securities  to  consummate  the  disposition  of  such
Registrable Securities.

     4.13. Use the Company's commercially  reasonable efforts to provide a CUSIP
number for the Registrable  Securities  prior to the effective date of the first
registration statement including Registrable Securities.

     4.14.  Use  commercially  reasonable  efforts  to  cause  the  Registerable
Securities covered by a registration  statement to be rated with the appropriate
rating agencies.

     4.15. Take such other actions as are  commercially  reasonably  required in
order to expedite or facilitate the  effectiveness  of the  registration  of the
Registrable Securities.

  Section 5.  Holders'  Obligations.  It shall be a condition  precedent  to the
obligations  of the Company to take any action  pursuant to this  Agreement with
respect to the  Registrable  Securities  of any  Selling  Holder of  Registrable
Securities that such Selling Holder shall:

     5.1. Furnish to the Company such information regarding such Selling Holder,
the number of the Registrable Securities owned by it, and the intended method of
disposition of such  securities as shall be required to effect the  registration
of such Selling  Holder's  Registrable  Securities,  and to  cooperate  with the
Company in preparing such registration; and

     5.2. Agree to sell their Registrable  Securities to the underwriters at the
same  price and on  substantially  the same  terms and  conditions  as the other
Persons on whose

                                      -12-


behalf the  registration  statement  was being  filed have  agreed to sell their
securities,  and to execute the underwriting agreement agreed to by the Majority
Selling Holders.

  Section 6. Expenses of  Registration.  The Selling  Holders shall bear and pay
all  expenses  incurred  in  connection  with  any   registration,   filing,  or
qualification of Registrable Securities with respect to any Demand Registrations
or Shelf  Registrations  for each Selling  Holder,  including all  registration,
filing and National  Association  of Securities  Dealers,  Inc. fees, all rating
agency fees,  stock  exchange  listing fees,  all fees and expenses of complying
with  securities or blue sky laws  (including  fees and expenses of underwriters
counsel), all word processing,  duplicating and printing expenses, messenger and
delivery  expenses,  the reasonable  fees and  disbursements  of counsel for the
Selling Holders, and of the Company's independent public accountants,  including
the  expenses  of  "cold  comfort"  letters  required  by or  incident  to  such
performance  and  compliance,   (the  "Registration  Expenses"),  any  fees  and
disbursements  of  underwriters,  and including all  underwriting  discounts and
commissions  relating to  Registrable  Securities  (which shall be paid on a pro
rata basis by the Selling  Holders),  including any expenses of any registration
proceeding  begun  pursuant  to Section 2 if the  registration  is  subsequently
withdrawn  at the request of the Majority  Selling  Holders;  provided  that the
Company shall pay all costs and expenses that the Company determines to incur on
its own behalf in its sole  discretion,  including  (i) the fees and expenses of
the  trustee  under the  indenture  pursuant  to which the Notes are  issued and
counsel  retained by such trustee,  (ii) any expenses of the Company incurred to
obtain confidential  treatment of records,  information or documents pursuant to
Section 4.9, and (iii) the fees and expenses of counsel to the Company.

  Section 7. Indemnification;  Contribution.  If any Registrable  Securities are
included in a registration statement under this Agreement:

     7.1. To the extent permitted by applicable law, the Company shall indemnify
and hold harmless each Selling  Holder,  each Person,  if any, who controls such
Selling  Holder  within the meaning of the  Securities  Act,  and each  officer,
director,  partner,  and  employee of such Selling  Holder and such  controlling
Person, against any and all losses, claims, damages,  liabilities and reasonable
expenses  (joint  or  several),   including   reasonable   attorneys'  fees  and
disbursements and expenses of investigation,  incurred by such party pursuant to
any actual or threatened action, suit, proceeding or investigation,  or to which
any of the foregoing  Persons may become subject under the  Securities  Act, the
Exchange Act or other  federal or state laws,  insofar as such  losses,  claims,
damages,  liabilities and reasonable expenses arise out of or are based upon any
of  the  following   statements,   omissions  or  violations   (collectively   a
"Violation"):

     (i) Any untrue  statement or alleged  untrue  statement of a material  fact
contained in such registration  statement,  including any preliminary prospectus
or final prospectus contained therein, or any amendments or supplements thereto;

     (ii) The  omission  or alleged  omission to state  therein a material  fact
required to be stated therein,  or necessary to make the statements  therein not
misleading; or


                                      -13-


     (iii) Any violation or alleged  violation by the Company of the  Securities
Act,  the Exchange  Act,  any  applicable  state  securities  law or any rule or
regulation  promulgated  under  the  Securities  Act,  the  Exchange  Act or any
applicable state securities law;

provided,  however, that the indemnification  required by this Section 7.1 shall
not  apply to  amounts  paid in  settlement  of any such  loss,  claim,  damage,
liability or expense if such  settlement is effected  without the consent of the
Company,  nor shall the  Company  be liable in any such case for any such  loss,
claim,  damage,  liability  or expense to the extent that it arises out of or is
based upon a Violation  which  occurs in reliance  upon and in  conformity  with
written information  furnished to the Company by the indemnified party expressly
for use in  connection  with  such  registration;  provided,  further,  that the
indemnity  agreement  contained  in  this  Section  7  shall  not  apply  to any
underwriter  to the  extent  that any such loss is based on or arises  out of an
untrue  statement or alleged untrue statement of a material fact, or an omission
or alleged  omission to state a material fact,  contained in or omitted from any
preliminary  prospectus  if the  final  prospectus  shall  correct  such  untrue
statement or alleged untrue statement, or such omission or alleged omission, and
a copy of the final  prospectus  has not been sent or given to such Person at or
prior to the  confirmation of sale to such Person if such  underwriter was under
an obligation to deliver such final  prospectus and failed to do so. The Company
shall also indemnify underwriters,  selling brokers, dealer managers and similar
securities  industry  professionals  participating  in the  distribution,  their
officers,  directors,  agents and  employees  and each Person who controls  such
Persons (within the meaning of Section 15 of the Securities Act or Section 20 of
the  Exchange  Act) to the same  extent as  provided  above with  respect to the
indemnification of the Selling Holders.

     7.2. To the extent  permitted by applicable  law, each Selling Holder shall
indemnify  and hold  harmless the Company,  each of its  directors,  each of its
officers who shall have signed the registration statement,  each Person, if any,
who controls  the Company  within the meaning of the  Securities  Act, any other
Selling Holder, any controlling Person of any such other Selling Holder and each
officer,  director,  partner, and employee of such other Selling Holder and such
controlling Person, against any and all losses, claims, damages, liabilities and
reasonable expenses (joint and several),  including  reasonable  attorneys' fees
and disbursements and expenses of investigation, incurred by such party pursuant
to any actual or threatened  action,  suit,  proceeding or investigation,  or to
which any of the  foregoing  Persons  may  otherwise  become  subject  under the
Securities Act, the Exchange Act or other federal or state laws, insofar as such
losses, claims, damages, liabilities and reasonable expenses arise out of or are
based upon any  Violation,  in each case to the extent  (and only to the extent)
that such  Violation  occurs in reliance  upon and in  conformity  with  written
information  furnished by such Selling  Holder  expressly  for use in connection
with such registration; provided, however, that (x) the indemnification required
by this  Section 7.2 shall not apply to amounts paid in  settlement  of any such
loss, claim, damage,  liability or expense if settlement is effected without the
consent of the relevant Selling Holder of Registrable Securities,  and (y) in no
event shall the amount of any  indemnity  under this  Section 7.2 exceed the net
proceeds from the applicable offering received by such Selling Holder.

     7.3. Promptly after receipt by an indemnified party under this Section 7 of
notice of the  commencement of any action,  suit,  proceeding,  investigation or
threat thereof made in writing for which such indemnified party may make a claim
under this Section 7, such


                                      -14-


indemnified  party shall deliver to the  indemnifying  party a written notice of
the  commencement  thereof  and the  indemnifying  party shall have the right to
participate in, and, to the extent the  indemnifying  party so desires,  jointly
with any other  indemnifying  party  similarly  noticed,  to assume the  defense
thereof with counsel mutually  satisfactory to the parties;  provided,  however,
that an indemnified  party shall have the right to retain its own counsel,  with
the fees and disbursements and expenses to be paid by the indemnifying party, if
representation  of  such  indemnified  party  by  the  counsel  retained  by the
indemnifying  party would be inappropriate due to actual or potential  differing
interests between such indemnified party and any other party represented by such
counsel  in such  proceeding.  The  failure  to  deliver  written  notice to the
indemnifying  party within a reasonable  time following the  commencement of any
such action, if prejudicial to its ability to defend such action,  shall relieve
such  indemnifying  party of any liability to the  indemnified  party under this
Section 7 but shall not relieve the indemnifying  party of any liability that it
may have to any indemnified party otherwise than pursuant to this Section 7. Any
fees and expenses  incurred by the  indemnified  party  (including  any fees and
expenses  incurred in connection with  investigating or preparing to defend such
action or  proceeding)  shall be paid to the  indemnified  party,  as  incurred,
within thirty (30) days of written  notice  thereof to the  indemnifying  party;
provided,  that such notice is  accompanied  by an  appropriate  undertaking  to
reimburse  the  indemnifying  party  if  it is  ultimately  determined  that  an
indemnified  party  is not  entitled  to  indemnification  hereunder.  Any  such
indemnified  party shall have the right to employ  separate  counsel in any such
action,  claim or proceeding and to participate in the defense thereof,  but the
fees and  expenses of such  counsel  shall be the  expenses of such  indemnified
party unless (i) the indemnifying party has agreed to pay such fees and expenses
or (ii) the indemnifying  party shall have failed to promptly assume the defense
of such  action,  claim or  proceeding  or (iii) the named  parties  to any such
action, claim or proceeding  (including any impleaded parties) include both such
indemnified  party and the indemnifying  party, and such indemnified party shall
have been  advised  by  counsel  that  there may be one or more  legal  defenses
available to it which are  different  from or in addition to those  available to
the  indemnifying  party and that the assertion of such defenses  would create a
conflict of interest such that counsel employed by the indemnifying  party could
not  faithfully  represent  the  indemnified  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  of such
action,  claim or  proceeding  on behalf  of such  indemnified  party,  it being
understood,  however,  that the indemnifying party shall not, in connection with
any one such action,  claim or proceeding or separate but substantially  similar
or related actions,  claims or proceedings in the same jurisdiction  arising out
of the same general  allegations or circumstances,  be liable for the reasonable
fees and expenses of more than one separate  firm of  attorneys  (together  with
appropriate local counsel) at any time for all such indemnified parties,  unless
in the reasonable  judgment of such indemnified party a conflict of interest may
exist between such indemnified  party and any other of such indemnified  parties
with  respect  to  such  action,  claim  or  proceeding,   in  which  event  the
indemnifying  party  shall be  obligated  to pay the fees and  expenses  of such
additional  counsel or counsels).  No  indemnifying  party shall be liable to an
indemnified party for any settlement of any action,  proceeding or claim without
the  written  consent of the  indemnifying  party,  which  consent  shall not be
unreasonably withheld.


                                      -15-


     7.4.  If  the   indemnification   required  by  this  Section  7  from  the
indemnifying  party is unavailable to an indemnified  party hereunder in respect
of any losses,  claims,  damages,  liabilities  or expenses  referred to in this
Section 7:

     (i) The 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  or  expenses  in such
proportion as is appropriate  to reflect the relative fault of the  indemnifying
party and  indemnified  parties in connection with the actions which resulted in
such losses,  claims,  damages,  liabilities  or expenses,  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 any Violation has been committed by, or relates to information  supplied
by, such indemnifying  party or indemnified  parties,  and the parties' relative
intent,  knowledge,  access to information and opportunity to correct or prevent
such Violation. The amount paid or payable by a party as a result of the losses,
claims,  damages,  liabilities and expenses referred to above shall be deemed to
include,  subject to the  limitations  set forth in Section 7.1 and Section 7.2,
any  legal  or other  fees or  expenses  reasonably  incurred  by such  party in
connection with any investigation or proceeding.

     (ii) The parties  hereto  agree that it would not be just and  equitable if
contribution pursuant to this Section 7.4 were determined by pro rata allocation
or by any other  method of  allocation  which  does not take  into  account  the
equitable  considerations  referred to in Section  7.4(i).  No Person  guilty of
fraudulent  misrepresentation  (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 misrepresentation.

     7.5. If indemnification is available under this Section 7, the indemnifying
parties shall  indemnify each  indemnified  party to the full extent provided in
this Section 7 without regard to the relative fault of such  indemnifying  party
or indemnified party or any other equitable consideration referred to in Section
7.4.

     7.6. The  obligations of the Company and the Selling Holders of Registrable
Securities  under this Section 7 shall survive the completion of any offering of
Registrable   Securities  pursuant  to  a  registration   statement  under  this
Agreement, and otherwise.

  Section 8. Transfer of Registration Rights. Rights with respect to Registrable
Securities may be  Transferred by a Holder to any Person in connection  with the
Transfer of Registrable Securities to such Person, in all cases, if (x) any such
Transferee  that is not a party  to  this  Agreement  shall  have  executed  and
delivered  to  the  Company  Notice  Parties  a  properly  completed   agreement
substantially  in the form of  Exhibit  A,  and (y) the  Transferor  shall  have
delivered to the Company  Notice  Parties,  no later than 15 days  following the
date of the Transfer,  written  notification of such Transfer  setting forth the
name of the Transferor,  name and address of the  Transferee,  and the number of
Registrable Securities which shall have been so Transferred.

  Section 9. Holdback.  Each Holder entitled  pursuant to this Agreement to have
Registrable Securities included in a registration statement prepared pursuant to
this Agreement, if so requested by the Underwriters'  Representative or Agent in
connection with an

                                      -16-


offering  of any  Registrable  Securities,  shall not effect any public  sale or
distribution of Registrable Securities, including a sale pursuant to Rule 144 or
Rule 144A  under the  Securities  Act  (except as part of such  underwritten  or
agented  registration),  during the five  business days prior to, and during the
90-day  period  beginning on, the date such  registration  statement is declared
effective under the Securities Act by the Commission,  provided that such Holder
is timely  notified  of such  effective  date in writing by the  Company or such
Underwriters'  Representative  or  Agent.  In order  to  enforce  the  foregoing
covenant,  the Company  shall be entitled to impose  stop-transfer  instructions
with respect to the Registrable  Securities of each Holder until the end of such
period.

  Section 10. Covenants of the Company.  The Company hereby agrees and covenants
as follows:

     10.1. The Company shall file as and when applicable, on a timely basis, all
reports required to be filed by it under the Exchange Act. If the Company is not
required to file reports  pursuant to the Exchange  Act, upon the request of any
Holder of Registrable Securities,  the Company shall make publicly available the
information  specified in subparagraph (c)(2) of Rule 144 of the Securities Act,
and take such further action as may be reasonably required from time to time and
as may be within the reasonable control of the Company, to enable the Holders to
Transfer  Registrable  Securities without  registration under the Securities Act
within the limitation of the exemptions provided by Rule 144 and Rule 144A under
the  Securities Act or any similar rule or regulation  hereafter  adopted by the
Commission.

     10.2.  The Company shall not,  directly or  indirectly,  (x) enter into any
merger,  consolidation or  reorganization  in which the Company shall not be the
surviving  corporation or (y) Transfer or agree to Transfer all or substantially
all  the  Company's  assets,   unless  prior  to  such  merger,   consolidation,
reorganization or asset Transfer,  the surviving  corporation or the Transferee,
respectively,  shall have  agreed in writing  to assume the  obligations  of the
Company  under this  Agreement,  and for that  purpose  references  hereunder to
"Registrable  Securities"  shall be deemed to include  the  securities,  if any,
which the  Holders of  Registrable  Securities  would be  entitled to receive in
exchange for Registrable  Securities pursuant to any such merger,  consolidation
or  reorganization.

     10.3. The Company shall use its  commercially  reasonable  efforts to cause
the Registrable  Securities covered by a registration statement to be rated with
the appropriate rating agencies.

  Section 11. Amendment, Modification and Waivers; Further Assurances.

     (i) This  Agreement  shall not be  amended  or  modified  except by written
instrument duly executed by each of the parties hereto which, in the case of the
Company,  shall  require the  signature  of the Chairman of the Company or other
person so authorized  by the Chairman of the Company or the  Company's  Board of
Directors.

     (ii) No waiver of any terms or conditions of this  Agreement  shall operate
as a waiver of any other breach of such terms and  conditions  or any other term
or condition, nor shall any failure to enforce any provision hereof operate as a
waiver of such

                                      -17-


provision or of any other provision hereof. No written waiver hereunder,  unless
it by its own terms explicitly  provides to the contrary,  shall be construed to
effect a continuing  waiver of the provisions being waived and no such waiver in
any instance  shall  constitute a waiver in any other  instance or for any other
purpose or impair the right of the party  against whom such waiver is claimed in
all other  instances or for all other purposes to require full  compliance  with
such provision.

     (iii) Each of the parties hereto shall execute all such further instruments
and  documents  and take all such  further  action as any other party hereto may
reasonably  require  in order to  effectuate  the  terms  and  purposes  of this
Agreement.

  Section 12.  Assignment;  Benefit.  This  Agreement and all of the  provisions
hereof  shall be binding  upon and shall  inure to the  benefit  of the  parties
hereto  and  their  respective  heirs,  assigns,  executors,  administrators  or
successors.  A Holder  may  Transfer  its rights  hereunder  to a  successor  in
interest to the Registrable  Securities owned by such assignor only as permitted
by Section 8.

  Section 13. Miscellaneous.

ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE,  WITHOUT GIVING REGARD TO THE
CONFLICT OF LAWS PRINCIPLES THEREOF.

the same counterpart.

     13.7. Severability.  If any provision of this Agreement shall be invalid or

negotiate in good faith as to appropriate amendments hereto.

Parties agrees that service of process by which any action is begun in any court
referred to in this  Section  13.8 shall be  effective if notice is delivered in
accordance with Section 13.2 and hereby irrevocably and  unconditionally  waives

in any other manner permitted by law.

further,  that this Agreement  shall  terminate with respect to any  Registrable
Securities  that  are  Transferred  to a  trust  or  other  entity  that  issues
pass-through or similar securities.

     13.10.  Attorneys' Fees. In any action or proceeding brought to enforce any
provision of this Agreement,  or where any provision  hereof is validly asserted
as a defense,  the  successful  party shall be  entitled  to recover  reasonable
attorneys'  fees  (including any fees incurred in any appeal) in addition to its
costs and expenses and any other available remedy.

     13.11. No Third Party Beneficiaries. Nothing herein expressed or implied is
